QUESTIONS & ANSWERS
ABOUT THE MERGER

Q: Why are the two companies proposing the merger?

A: The Internet and telecommunications industries continue to change dramatically as a result of developments in technology, consumer needs and the range of product offerings made possible by these changes. We believe that companies that offer a full range of software products for communications service providers will be the most effective competitors in a market created by the rapid development and convergence of these two industries. We believe that our merger will create a global leader that will provide a broad range of carrier-class software to wireless and wireline carriers, portal operators and Internet service providers. When the merger is completed, we expect the combined company to be a leading provider of highly scalable infrastructure and application software enabling the delivery of e-mail, voicemail, unified messaging, directory, and wireless Internet access for IP-based networks.

To review the reasons for the merger in greater detail, see pages 47 through 50.

Q: What is the proposed merger?

A: In the proposed merger, Software.com will merge with a wholly-owned subsidiary of Phone.com. Software.com will survive the merger as a wholly- owned subsidiary of Phone.com. The merger agreement is attached to this joint proxy statement/prospectus as Annex A. You are encouraged to read it carefully.

Q: What will I receive in the merger?

A: Phone.com stockholders:

Following the merger, each share of Phone.com common stock and each option to purchase Phone.com common stock will remain outstanding.

Software.com stockholders:

Following the merger:

. Software.com common stockholders will receive, in exchange for each of their Software.com shares, 1.6105 shares of Phone.com common stock.

. Instead of fractional shares of Phone.com common stock, Software.com stockholders will receive cash in an amount equal to such fraction multiplied by the average of the closing prices reported on the Nasdaq National Market for Phone.com common stock for the ten trading days immediately preceding the effective date of the merger.

. Each option or warrant to purchase Software.com common stock outstanding immediately before the completion of the merger will automatically become an option or warrant to purchase shares of Phone.com common stock. The number of shares of Phone.com common stock which may be purchased under such option or warrant will be equal to the product of the number of Software.com shares that were purchasable before the merger multiplied by 1.6105. The exercise price per share will be the pre-merger exercise price divided by 1.6105.

Q: What are the United States federal income tax consequences of the merger?

A: We expect that, in general, Phone.com stockholders, Software.com and Software.com stockholders will not recognize gain or loss for United States federal income tax purposes as a result of the merger, except for gain or loss attributable to cash received by Software.com stockholders instead of fractional shares. It is a condition to the merger that both Phone.com and Software.com receive legal opinions to the effect that the merger will constitute a "reorganization" within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended.

The tax consequences of the merger to you will depend on your own situation. You should consult your tax advisors for a full understanding of these tax consequences.

Q: What do I need to do to get my Phone.com shares?

A: Phone.com stockholders will keep their existing certificates. After the merger is completed Phone.com will send Software.com stockholders written instructions for exchanging their stock certificates. Software.com stockholders should not send in their stock certificates now.

1

Q: When do you expect to complete the merger?

A: We expect to complete the merger in the fourth calendar quarter of 2000. We are working toward completing the merger as quickly as possible and expect to do so shortly after the stockholder meetings, provided that we have obtained the regulatory clearances and approvals necessary for the merger.

Q: What do I need to do now?

A: First, carefully read this document. There are several ways your shares can be represented at the special meeting. You can indicate on the enclosed proxy card how you want to vote and then sign and mail the proxy card in the enclosed return envelope as soon as possible. You can also cast your vote electronically by telephone by calling the number on your proxy card or over the Internet by going to the web site designated on your proxy card.

If you do not include instructions on how to vote your properly signed proxy card, your common stock will be voted "FOR" approval of the proposals discussed in this joint proxy statement/prospectus. If you do not send in your signed proxy card, or fail to vote by telephone or the Internet, your common stock will not be voted at the meetings and will not be counted for purposes of establishing a quorum.

Your vote is important regardless of the number of shares that you own.

Q: If my broker holds my shares in "street name," will my broker vote my shares?

A: Your broker will not vote your shares unless you follow the directions your broker provides to you regarding how to vote your shares. For Software.com stockholders, if you fail to provide your broker with instructions, it will have the same effect as a vote against the merger. For Phone.com stockholders, if you fail to provide your broker with instructions, it will have no effect in determining the number of votes for or against the proposed share issuance and will have the same effect as a vote against the other proposals to be considered at the meeting of Phone.com's stockholders.

Q: What do I do if I want to change my vote?

A: You can change your vote by sending in a written notice of revocation or a later-dated, signed proxy card to your company's secretary before your stockholders meeting or by attending the meeting in person and voting. You also can change your vote by voting by telephone or over the Internet at a later time.

Q: Who should I call with questions?

A: Phone.com stockholders:

If you have any questions, please call Doug Solomon, Associate General Counsel, at (650) 817-7161.

Software.com stockholders:

If you have any questions, please call Craig Shelburne, Senior Vice President and General Counsel, at (805) 882-2470.

What You Will Receive in the Merger (Page 66)

Phone.com stockholders:

After the merger, each share of Phone.com common stock will remain outstanding and each option to purchase Phone.com common stock will also remain outstanding.

Software.com stockholders:

In the merger, each Software.com share will be exchanged for 1.6105 shares of Phone.com common stock.

Instead of fractional shares of Phone.com common stock, Software.com stockholders will receive cash in an amount equal to such fraction multiplied by the average of the closing prices reported on the Nasdaq National Market for Phone.com common stock for the ten trading days immediately preceding the effective date of the merger.

Each option or warrant to purchase Software.com common stock outstanding immediately before the completion of the merger will automatically become an option or warrant to purchase shares of Phone.com common stock. The number of shares of Phone.com common stock which may be purchased under such option or warrant will be equal to the product of the number of Software.com shares that were purchasable before the merger multiplied by 1.6105. The exercise price per share will be the pre-merger exercise price divided by 1.6105.

Ownership of Phone.com After the Merger

We estimate that the number of shares of Phone.com common stock issued to Software.com stockholders in the merger will constitute approximately 50% of the outstanding common stock of the combined company after the merger.

Record Date for Voting; Required Votes

Phone.com stockholders:

Each holder of record, as of , 2000, of Phone.com common stock is entitled to cast one vote per share. The affirmative vote, in person or by proxy, of at least a majority of the votes properly cast, is required to approve the issuance of shares of Phone.com common stock in the merger. In addition, the affirmative vote, in person or by proxy, of a majority of the shares outstanding as of the record date is required to approve and adopt the amendment to Phone.com's certificate of incorporation to change the name of Phone.com to and to increase the number of authorized shares of Phone.com common stock.

Stockholders representing approximately 13.0% of the voting power of Phone.com, as of July 31, 2000, have entered into voting agreements with Software.com in which they agreed to vote in favor of the share issuance and the name change amendment. We have attached a copy of the form of Phone.com voting agreement as Annex D to this document. You should read it in its entirety.

Software.com stockholders:

Each holder of record, as of , 2000, of Software.com common stock is entitled to cast one vote per share.

The completion of the merger depends on the satisfaction or waiver of a number of conditions, including, but not limited to, the following:

4

Phone.com's certificate of incorporation to change the name of Phone.com;

. expiration or termination of the waiting period applicable to the merger under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, which waiting period terminated on August 30, 2000;

. absence of any stop order suspending the effectiveness of the registration statement relating to the shares of Phone.com common stock to be issued in the merger and approval of those shares for trading on the Nasdaq National Market; and

. receipt of legal opinions that the merger will be treated as a "reorganization" within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended.

Termination of the Merger Agreement (Page 73)

1. Phone.com and Software.com may mutually agree to terminate the merger agreement if the board of directors of each determines to do so by a vote of a majority of the entire board of directors.

2. Either Phone.com or Software.com may terminate the merger agreement if:

. the merger is not completed by March 31, 2001, or June 30, 2001 under certain circumstances, so long as the party seeking to terminate did not prevent the consummation of the merger by failing to perform any of its obligations under the merger agreement;

. Phone.com stockholders do not approve the issuance of shares of Phone.com common stock in the merger and the amendment to Phone.com's certificate of incorporation to change the name of Phone.com;

. Software.com stockholders do not approve the adoption of the merger agreement and the transactions contemplated thereby;

. any governmental entity issues a nonappealable final order that has a material adverse effect on Phone.com or the effective operation of the combined company following the merger, or a required regulatory approval is denied;

. the other party materially breaches or fails to perform any of its representations, warranties, covenants or other agreements in the merger agreement, which breach is incurable or is not cured within 15 business days of written notice thereof; or

. prior to the Phone.com or Software.com special meeting, as the case may be, the other party's board of directors withdraws, modifies, qualifies or fails to reconfirm its recommendations discussed below under "Board Recommendations," or the other party materially breaches its obligations not to solicit alternative transactions.

Termination Fees and Stock Option Agreements (Pages 73-81)

If either Phone.com or Software.com terminates the merger agreement because of a failure to obtain stockholder approval and there was a publicly announced proposal for an alternative transaction involving acquisition of at least 50 percent of its stock, it will have to pay to the other party all of its expenses incurred in connection with the merger agreement. In addition, in certain cases in which the merger agreement is terminated, either party may have to pay a termination fee of $195 million, less any expenses already paid.

Both Phone.com and Software.com have entered into stock option agreements under which each has granted to the other party an option to purchase up to 19.9% of its shares. The exercise price of the option for Phone.com shares is $78.0625 per share and the exercise price for the option for Software.com shares is $125.7197 per share. The stock option agreements are attached as Annexes B and C. The options are exercisable by a party when such party is entitled to receive a termination fee upon the termination of the merger agreement.

The termination fees and stock options could discourage other companies from trying or proposing

5

to combine with either Software.com or Phone.com. The total termination fees, expenses and profit realizable under a stock option agreement by either Phone.com or Software.com is limited to $230,454,545.

Our Reasons for the Merger (Pages 47-50)

Our boards of directors have unanimously approved the merger agreement and the transactions associated with it, and have determined that the merger and the transactions associated with it are in the best interests of our respective stockholders. In reaching their respective decisions, our boards of directors considered that the combination of the companies will likely offer customers a broad range of carrier-class software.

Board Recommendations (Pages 47-50)

Phone.com stockholders:

The Phone.com board of directors believes that the merger is in your best interests and unanimously recommends that Phone.com stockholders vote FOR approval of the issuance of shares of Phone.com common stock pursuant to the merger agreement and an amendment to Phone.com's certificate of incorporation to change the name of Phone.com. In addition, the Phone.com board of directors recommends a vote for the increase in share capital.

Software.com stockholders:

The Software.com board of directors believes that the merger is in your best interests and unanimously recommends that Software.com stockholders vote "FOR" adoption of the merger agreement.

Opinions of Financial Advisors (Pages 51-62)

In deciding to approve the merger, each of our boards of directors considered opinions from our respective financial advisors.

Phone.com's financial advisor, Credit Suisse First Boston Corporation, has delivered a written opinion to the Phone.com board of directors as to the fairness, from a financial point of view, to Phone.com of the exchange ratio provided for in the merger. The full text of Credit Suisse First Boston's written opinion, dated August 8, 2000, is attached to this document as Annex J. Phone.com encourages you to read this opinion carefully in its entirety for a description of the procedures followed, assumptions made, matters considered and limitations on the review undertaken. Credit Suisse First Boston's opinion is directed to the Phone.com board of directors and does not constitute a recommendation to any stockholder as to any matter relating to the merger.

In deciding to approve the merger, the Software.com board of directors considered the opinion of its financial advisor, Morgan Stanley & Co. Incorporated, that, as of the date of its opinion, and subject to and based on the considerations referred to in its opinion, the exchange ratio pursuant to the merger agreement was fair, from a financial point of view, to the holders of shares of Software.com common stock. The full text of this opinion is attached as Annex K. Software.com urges its stockholders to read the opinion of Morgan Stanley carefully and in its entirety. Morgan Stanley's opinion is directed to the Software.com board of directors and does not constitute a recommendation to any stockholder as to any matter relating to the merger.

Certain United States Federal Income Tax Considerations (Pages 62-63)

The exchange of Software.com common stock for Phone.com common stock, other than cash paid for fractional shares, is intended to be tax-free to Software.com stockholders for United States federal income tax purposes. Tax matters are very complicated and the tax consequences of the merger to you will depend on your own personal circumstances. You should consult your tax advisors for a full understanding of all of the tax consequences of the merger to you.

Anticipated Accounting Treatment (Pages 63-64)

We expect that the merger will be accounted for as a pooling of interests. However, pooling-of- interests accounting treatment is not a condition to the consummation of the merger.

Interests of Directors and Officers in the Merger (Pages 64-65)

When considering the recommendations of Software.com's and Phone.com's boards of directors, you should be aware that certain Software.com and Phone.com directors, officers and stockholders have interests in the merger that are different from, or are in addition to, yours. These interests include the potential acceleration of stock options held by some of Phone.com's and Software.com's officers upon completion of the merger, the post-merger membership of three current Software.com directors and three current Phone.com directors on the board of directors of the combined company and the indemnification of directors and officers of Software.com against certain liabilities both before and after the merger. In addition, Donald J. Listwin, currently a member of Software.com's board of directors, is expected to resign from the Software.com board and join Phone.com as President and Chief Executive Officer. Mr. Listwin has also been designated by both Phone.com and Software.com to serve as President and Chief Executive Officer and as a member of the board of directors of the combined company.

Regulatory Clearances and Approvals (Page 65)

Comparative Per Share Data

The following tables set forth certain historical per share data of Phone.com and Software.com and combined per share data on an unaudited pro forma basis after giving effect to the merger on a pooling of interests accounting basis assuming the issuance of 1.6105 shares of Phone.com common stock in exchange for each share of Software.com common stock. The data is derived from and should be read in conjunction with "Phone.com Selected Historical Consolidated Financial Data," "Software.com Selected Historical Consolidated Financial Data," "Selected Unaudited Pro Forma Combined Condensed Financial Data" and the historical consolidated financial statements of Phone.com and Software.com included in this joint proxy statement/prospectus. The unaudited pro forma combined financial data are not necessarily indicative of the operating results that would have been achieved had the transaction been in effect as of the beginning of the periods presented and should not be construed as representative of future operations. Neither Phone.com nor Software.com declared any cash dividends related to their respective common stock during the periods presented.

The historical book value per share is computed by dividing stockholders' equity by the number of shares of common stock outstanding at the end of each period. The pro forma combined net loss per share for the years ended June 30, 1998, 1999 and 2000 includes Phone.com's net loss per share for the years ended June 30, 1998, 1999 and 2000, combined with Software.com's net loss per share for the years ended December 31, 1998 and 1999 and the year ended June 30, 2000, respectively. The Software.com equivalent pro forma combined net loss per share amounts are calculated by multiplying the pro forma combined per share amounts by the exchange ratio of 1.6105 shares of Phone.com common stock for each share of Software.com common stock. The pro forma combined book value per share is computed by dividing pro forma stockholders' equity by the pro forma number of shares of common stock outstanding at the end of the period. The Software.com equivalent pro forma combined book value per share amount is calculated by multiplying the pro forma combined per share amount by the exchange rates of 1.6105 shares of Phone.com common stock for each share of Software.com common stock.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

Any statements in this document about our expectations, beliefs, plans, objectives, assumptions or future events or performance are not historical facts and are forward-looking statements. These statements are often, but not always, made through the use of words or phrases such as "believe," "will likely result," "expect," "will continue," "anticipate," "estimate," "intend," "plan," "projection," "would" and "outlook." Accordingly, these statements involve estimates, assumptions and uncertainties which could cause actual results to differ materially from those expressed in them. Any forward-looking statements are qualified in their entirety by reference to the factors discussed throughout this document. The following cautionary statements identify important factors that could cause our actual results to differ materially from those projected in the forward-looking statements made in this document. Among the key factors that have a direct bearing on our results of operations are:

. general economic and business conditions; the existence or absence of adverse publicity; changes in marketing and technology; changes in political, social and economic conditions;

. competition in the Internet and wireless and wireline telecommunications sectors; general risks of the wireless and wireline telecommunications and Internet sectors;

. success of acquisitions and operating initiatives; changes in business strategy or development plans; management of growth;

. dependence on senior management; business abilities and judgment of personnel; availability of qualified personnel; labor and employee benefit costs;

. our ability to integrate effectively the two companies' technology, operations and personnel in a timely and efficient manner;

. ability of the combined company to retain and hire key executives, technical personnel and other employees;

. ability of the combined company to manage its growth and the difficulty of successfully managing a larger, more geographically dispersed organization;

. ability of the combined company to successfully manage its changing relationships with customers, suppliers, value added resellers, and strategic partners;

. ability of the combined company's customers to accept new product offerings; and

. the timing of, and regulatory and other conditions associated with, the completion of the merger and the ability of the combined company to combine operations and obtain revenue enhancements following the merger.

These factors and the risk factors referred to below could cause actual results or outcomes to differ materially from those expressed in any forward- looking statements made by us, and you should not place undue reliance on any such forward-looking statements. Further, any forward-looking statement speaks only as of the date on which it is made and we undertake no obligation to update any forward-looking statement or statements to reflect events or circumstances after the date on which such statement is made or to reflect the occurrence of unanticipated events. New factors emerge from time to time, and it is not possible for us to predict which will arise. In addition, we cannot assess the impact of each factor on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements.

RISK FACTORS

Stockholders of Phone.com and Software.com should consider the following factors, in addition to the other information contained in this document. By voting in favor of the merger, current Software.com stockholders will be choosing to invest in Phone.com common stock and current Phone.com stockholders will face dilution of their ownership interest in Phone.com.

Risks Relating to the Proposed Merger

Phone.com and Software.com may not achieve the benefits they expect from the merger which may have a material adverse effect on the combined company's business, financial and operating results.

Phone.com and Software.com entered into the merger agreement with the expectation that the merger will result in benefits to the combined company arising out of the creation of a global provider of a broad range of carrier- class software to wireless and wireline carriers, portal operators and Internet service providers. To realize any benefits or synergies from the merger, the combined company will face the following post merger challenges:

. combining product and service offerings effectively and quickly;

. retaining and assimilating the management and employees of each company;

. offering the existing products of each company to the other company's customers;

. retaining existing customers, strategic partners and suppliers of each company;

. developing new products that utilize the assets and resources of both companies; and

. developing and maintaining uniform standards, controls, procedures, policies and information systems.

If the combined company is not successful in addressing these and other challenges, then the benefits of the merger will not be realized and, as a result, the combined company's operating results and the market price of the combined company's common stock may be adversely affected. Further, neither Phone.com nor Software.com can assure you that the growth rate of the combined company will equal the historical growth rates experienced by Phone.com and Software.com.

Software.com stockholders will receive 1.6105 shares of Phone.com common stock for each share of Software.com common stock despite changes in the market value of Software.com common stock or Phone.com common stock.

Each share of Software.com common stock will be exchanged for 1.6105 shares of Phone.com common stock upon completion of the merger. This exchange ratio is a fixed number and will not be adjusted for changes in the market price of either Software.com common stock or Phone.com common stock. Neither party is permitted to terminate the merger agreement solely because of changes in the market price of Phone.com or Software.com common stock. Consequently, the specific dollar value of Phone.com common stock to be received by Software.com stockholders will depend on the market value of Phone.com at the time of completion of the merger and may decrease from the date that you submit your proxy. You are urged to obtain recent market quotations for Phone.com common stock and Software.com common stock. Phone.com cannot predict or give any assurances as to the market price of Phone.com common stock at any time before or after the merger. The prices of Phone.com common stock and Software.com common stock may vary because of factors such as:

. changes in the business, operating results or prospects of Phone.com or Software.com;

. actual or anticipated variations in quarterly results of operations;

. market assessments of the likelihood that the merger will be completed;

. the timing of the completion of the merger;

. sales of Phone.com common stock or Software.com common stock;

13

. additions or departures of key personnel;

. announcements of significant acquisitions, strategic partnerships, joint ventures or capital commitments;

. conditions or trends in the Internet and telecommunications industries;

. announcements of technological innovations, new products or services by Phone.com, Software.com or their competitors;

. changes in market valuations of other Internet software companies;

. the prospects of post-merger operations;

. regulatory considerations; and

. general market and economic conditions.

If the merger is successfully completed, holders of Software.com common stock will become holders of Phone.com common stock. Phone.com's business differs from Software.com's business, and Phone.com's results of operations, as well as the price of Phone.com common stock, may be affected by factors different than those affecting Software.com's results of operations and the price of Software.com common stock. In particular, Phone.com's business is not operationally profitable and it is not certain that it will achieve profitability in the foreseeable future.

The market price of the combined company's common stock may decline as a result of the merger.

The market price of the combined company's common stock may decline as a result of the merger for a number of reasons including if:

. the integration of Phone.com and Software.com is not completed in a timely and efficient manner;

. the combined company does not achieve the perceived benefits of the merger as rapidly or to the extent anticipated by financial or industry analysts;

. the effect of the merger on the combined company's financial results is not consistent with the expectations of financial or industry analysts; or

. significant stockholders of Phone.com and Software.com decide to dispose of their shares following completion of the merger.

Phone.com's and Software.com's officers and directors have conflicts of interest that may influence them to support or approve the merger.

The directors and officers of Phone.com and Software.com participate in arrangements and have continuing indemnification against liabilities that provide them with interests in the merger that are different from, or in addition to, yours including the following:

. Phone.com has agreed to cause the surviving corporation in the merger to indemnify each present and former Software.com officer and director against liabilities arising out of such person's services as an officer or director;

. Phone.com will cause the surviving corporation to maintain officers' and directors' liability insurance to cover any such liabilities for the next six years;

. Phone.com and Software.com have agreed that Software.com shall be entitled to designate three individuals currently on Software.com's board to the combined company's board of directors, and Phone.com shall be entitled to designate three of the six current Phone.com directors to continue on the board of directors of the combined company following the merger;

. Phone.com and Software.com have agreed that Donald J. Listwin, a member of Software.com's board, will serve as the combined company's President and Chief Executive Officer. Phone.com and Software.com also agreed that Alain Rossmann, Phone.com's current Chief Executive Officer, will serve

14

as the combined company's Executive Vice President and Chairman of the Board of Directors, that John L. MacFarlane, Software.com's current Chief Executive Officer, will serve as the combined company's Executive Vice President and that Alan Black, Phone.com's current Chief Financial Officer and Vice President of Finance and Administration, will serve as Chief Financial Officer for the combined company following the merger;

. the merger may result in a change of control of Software.com and Software.com's officers and key employees have entered into change of control agreements that provide for one-half of the unvested portion of any stock option held by the officer or employee to accelerate and become exercisable in the event that the officer or employee is involuntarily terminated or assigned a position of lesser responsibility or compensation following a change of control; and

. the merger may result in a change of control of Phone.com and Phone.com's officers and key employees have entered into change of control agreements that provide for all of the unvested portion of any stock option or restricted stock held by the officer or employee to accelerate and become exercisable in the event that the officer or employee is terminated other than for cause or assigned a position of lesser responsibility or compensation within 18 months following a change of control transaction.

For the above reasons, the directors and officers of Phone.com and Software.com may have been more likely to vote to approve the merger agreement than if they did not hold these interests. Phone.com stockholders and Software.com stockholders should consider whether these interests may have influenced these directors and officers to support or recommend the merger. You should read more about these interests under "The Merger--Interests of Directors and Officers in the Merger."

Failure to complete the merger could negatively impact Phone.com's and/or Software.com's stock price, future business and operations.

If the merger is not completed for any reason, Phone.com and Software.com may be subject to a number of material risks, including the following:

. Phone.com may be required under certain circumstances to pay Software.com, and Software.com may be required under certain circumstances to pay Phone.com, a substantial termination fee;

. benefits that the combined company expects to realize from the merger, such as the potentially enhanced financial and competitive position of the combined company, would not be realized;

. Phone.com stockholders may experience dilution to their stock ownership because the stock option granted to Software.com by Phone.com may become exercisable and Software.com stockholders may experience dilution of their stock ownership because the stock option granted to Phone.com by Software.com may become exercisable;

. Phone.com and Software.com may no longer qualify as an entity that may be a party to a business combination for which pooling-of-interests accounting would be available;

. the price of Phone.com and/or Software.com common stock may decline to the extent that the relevant current market price reflects a market assumption that the merger will be completed and that Donald J. Listwin will assume the role of President and Chief Executive Officer of the combined company;

. costs related to the merger, such as legal, accounting and financial printing fees, as well as a portion of the investment banking fees, must be paid even if the merger is not completed; and

. the diversion of management attention from the day-to-day business of each company and the unavoidable disruption to its employees and its relationships with customers and suppliers, during the period before consummation of the merger may make it difficult for each company to regain its financial and market position if the merger does not occur.

15

Uncertainty regarding the merger and the effects of the merger could cause each company's customers strategic partners or key employees to delay or defer decisions.

Phone.com's and/or Software.com's customers and strategic partners, in response to the announcement of the merger, may delay or defer decisions, which could have a material adverse effect on the business of the relevant company, regardless of whether the merger is ultimately completed. Similarly, current and prospective Phone.com and/or Software.com employees may experience uncertainty about their future roles with the combined company. This may adversely affect Phone.com's and/or Software.com's ability to attract and retain key management, sales, marketing and technical personnel. Further, if the merger is terminated and either company's board of directors determines to seek another merger or business combination, there can be no assurance that it will be able to find a partner on terms similar to those provided for in this merger agreement. In addition, while the merger agreement is in effect and subject to very narrowly defined exceptions, each party is prohibited from soliciting, initiating or encouraging or entering into certain extraordinary transactions, such as a merger, sale of assets or other business combination, with any third party.

The costs of the proposed merger could adversely affect combined financial results.

Phone.com and Software.com expect to incur direct transaction costs of approximately $100.0 million in connection with the merger. If the benefits of the merger do not exceed the costs associated with the merger, including any dilution to the stockholders of both companies resulting from the issuance of shares in connection with the merger, the combined company's financial results, including earnings per share, could be adversely affected.

Failure to qualify for pooling-of-interests accounting treatment may impact reported operating results.

While the merger is expected to qualify for pooling-of-interests accounting treatment, pooling treatment is not a condition to the merger. If the merger does not qualify for pooling-of-interests accounting treatment, the purchase method of accounting will apply. Under the purchase method, the fair value of the shares of Phone.com common stock issued in the merger would be recorded as the cost of acquiring the business of Software.com. That cost would be allocated to the individual assets acquired and liabilities assumed according to their respective estimated fair values, with the excess of the fair value of shares of Phone.com common stock over the estimated fair value of net assets acquired recorded as goodwill, to be amortized over a period of 3 to 7 years.

Purchase accounting treatment would have a material adverse effect on the reported operating results of the combined company as compared to pooling-of- interests accounting treatment because of potential charges to the combined company's earnings for in-process research and development and amortization of goodwill and other intangible assets required by purchase accounting treatment which would result in the combined company reporting a net loss for a longer period of time.

Phone.com and Software.com may not be able to obtain the required regulatory approvals for completion of the merger.

Phone.com and Software.com cannot complete the merger until they give notification and furnish information to the Federal Trade Commission and the Antitrust Division of the Department of Justice and observe a statutory waiting period requirement. Phone.com and Software.com filed the required notification and report forms with the Federal Trade Commission and the Antitrust Division and the waiting period was terminated on August 30, 2000. At any time before or after the effective time of the merger, and notwithstanding that the waiting period has terminated or the merger may have been consummated, the Federal Trade Commission, the Antitrust Division or any state could take any action under the applicable antitrust or competition laws as it deems necessary or desirable. This action could include seeking to enjoin the completion of the merger. Private parties may also institute legal actions under the antitrust laws under some circumstances.

Risks Relating to the Business and Operations of Phone.com

Phone.com's future profitability is uncertain because it has a limited operating history.

Because Phone.com commenced operations in December 1994 and commercially released its first products in June 1996, Phone.com has only a limited operating history on which you can base your evaluation of its business. In addition, until its 1999 fiscal year, Phone.com has had less than $2.25 million in annual revenue, which represents a small percentage of its future anticipated annual revenues.

Phone.com may not continue to grow or achieve profitability.

Phone.com faces a number of risks encountered by early stage companies in the wireless telecommunications and Internet software industries, including:

. its need for network operators to launch and maintain commercial services utilizing its products;

. the uncertainty of market acceptance of commercial services utilizing its products;

. its substantial dependence on products with only limited market acceptance to date;

. its need to introduce reliable and robust products that meet the demanding needs of network operators and wireless telephone manufacturers;

. its need to expand its marketing, sales, consulting, and support organizations, as well as its distribution channels;

. its ability to anticipate and respond to market competition;

. its need to manage expanding operations; and

. its dependence upon key personnel.

Phone.com's business strategy may not be successful, and it may not successfully address these risks.

Phone.com may not achieve or sustain revenue or profit goals.

Because Phone.com expects to continue to incur significant product development, sales and marketing, and administrative expenses, Phone.com will need to generate significant revenues to become profitable and sustain profitability on a quarterly or annual basis. Phone.com may not achieve or sustain its revenue or profit goals, and Phone.com's ability to do so depends on a number of factors outside of its control, including the extent to which:

. there is market acceptance of commercial services utilizing Phone.com's products;

. Phone.com's competitors announce and develop, or lower the prices of, competing products; and

. Phone.com's strategic partners dedicate resources selling Phone.com's products and services.

As a result, Phone.com may not be able to increase revenue or achieve profitability on a quarterly or annual basis.

Phone.com's quarterly operating results are subject to significant fluctuations, and its stock price may decline if it does not meet expectations of investors and analysts.

Phone.com's quarterly revenues and operating results are difficult to predict and may fluctuate significantly from quarter to quarter due to a number of factors, some of which are outside of our control. These factors include, but are not limited to:

. delays in market acceptance or implementation by Phone.com's customers of its products and services;

. changes in demand by Phone.com's customers for additional products and services;

. Phone.com's lengthy sales cycle;

. Phone.com's concentrated target market and the potentially substantial effect on total revenues that may result from the gain or loss of business from each incremental network operator customer;

17

. introduction of new products or services by Phone.com or its competitors;

. delays in developing and introducing new products and services;

. changes in Phone.com's pricing policies or those of its competitors or customers;

. changes in Phone.com's mix of domestic and international sales;

. risks inherent in international operations;

. changes in Phone.com's mix of license, consulting and maintenance and support services revenues; and

. changes in accounting standards, including standards relating to revenue recognition, business combinations and stock-based compensation.

Most of Phone.com's expenses, such as employee compensation and lease payments for facilities and equipment, are relatively fixed and growing. In addition, Phone.com's expense levels are based, in part, on its expectations regarding future revenues. As a result, any shortfall in revenues relative to Phone.com's expectations could cause significant changes in its operating results from quarter to quarter. Due to the foregoing factors, Phone.com believes period to period comparisons of its revenue levels and operating results are not meaningful. You should not rely on Phone.com's quarterly revenues and operating results to predict its future performance.

Phone.com may be unable to successfully integrate acquired companies into its business or achieve the expected benefits of the acquisitions.

Phone.com's acquisitions of AtMotion and Paragon, which were completed in February 2000 and March 2000, respectively, and its acquisition of Onebox, which was completed in April 2000, will require further integration of the products, business and operations of these companies with Phone.com. Phone.com may not be able to successfully assimilate the personnel, operations and customers of these companies into its business. Additionally, Phone.com may fail to achieve the anticipated synergies from the acquisitions, including product integration, marketing, product development, distribution and other operational synergies.

The integration process may further strain Phone.com's existing financial and managerial controls and reporting systems and procedures. This may result in the diversion of management and financial resources from Phone.com's core business objectives. In addition, Phone.com is relatively inexperienced in managing significant facilities or operations in geographically distant areas. Finally, Phone.com cannot be certain that it will be able to retain these companies' key employees.

Any future merger or acquisition of companies or technologies may result in disruptions to Phone.com's business and/or the distraction of its management.

In addition to our pending merger with Software.com, Phone.com may merge with or acquire technologies or companies in the future. Entering into any business combination entails many risks, any of which could materially harm its business, including:

. diversion of management's attention from other business concerns;

. failure to assimilate the merged or acquired company with Phone.com's pre-existing businesses;

. potential loss of key employees from either Phone.com's pre-existing business or the merged or acquired business;

. dilution of Phone.com's existing stockholders as a result of issuing equity securities; and

. assumption of liabilities of the merged or acquired company.

To date, Phone.com has completed acquisitions of seven companies or their assets, consisting of APiON, Angelica Wireless, AtMotion, Paragon, Onebox, Velos and MyAble and has pending its merger with Software.com. Phone.com may merge with or acquire other complementary businesses and technologies in the future. Phone.com may not be able to identify other future suitable merger or acquisition candidates, and even if

18

it does identify suitable candidates, it may not be able to make these transactions on commercially acceptable terms, or at all. If Phone.com does merge with or acquire other companies, it may not be able to realize the benefits it expected to achieve at the time of entering into the transaction. In any future merger or acquisition,
Phone.com will likely face the same risks as discussed above. Further, Phone.com may have to incur debt or issue equity securities to pay for any future merger or acquisition, the issuance of which could be dilutive to its existing stockholders.

Phone.com may not be successful in making strategic investments.

In the future, Phone.com may make strategic investments in other companies. Some of these investments may be made in immature businesses with unproven track records and technologies, and have a high degree of risk, with the possibility that Phone.com may lose the total amount of its investments. Phone.com may not be able to identify suitable investment candidates, and even if it does, it may not be able to make those investments on acceptable terms, or at all. In addition, even if Phone.com makes investments, it may not gain strategic benefits from those investments.

Phone.com's sales cycle is long, and its stock price could decline if sales are delayed or cancelled.

Quarterly fluctuations in Phone.com's operating performance are exacerbated by its sales cycle, which is lengthy, typically between six and twelve months, and unpredictable. Many factors outside Phone.com's control add to the lengthy education and customer approval process for its products. For example, many of Phone.com's prospective customers have neither budgeted expenses for the provision of Internet-based services to wireless subscribers nor specifically dedicated personnel for the procurement and implementation of its products and services. As a result, Phone.com spends a substantial amount of time educating customers regarding the use and benefits of its products and they in turn spend a substantial amount of time performing internal reviews and obtaining capital expenditure approvals before purchasing Phone.com's products. Further, the emerging and evolving nature of the market for Internet-based services via wireless telephones may lead prospective customers to postpone their purchasing decisions. Any delay in sales of Phone.com's products could cause Phone.com's quarterly operating results to vary significantly from projected results, which could cause Phone.com's stock price to decline.

Phone.com's success depends on acceptance of its products and services by network operators and their subscribers.

From inception through June 30, 2000, Phone.com has generated a significant portion of its total cumulative revenues from fees paid to it by wireless telephone manufacturers that embed its browser in their wireless telephones. However, Phone.com's future success depends on its ability to increase revenues from sales of its UP.Link Server Suite and related server-based software and services to new and existing network operator customers and on market acceptance of new products and services, including its MyPhone wireless Internet portal framework and related server-based communications applications software products, and Phone.com may not be able to achieve widespread adoption of these products and services by these customers. This dependence is exacerbated by the relatively small number of network operators worldwide. To date, only a limited number of network operators have implemented and deployed services based on Phone.com's products. Phone.com cannot assure you that network operators will widely deploy or successfully market services based on its products, or that large numbers of subscribers will use these services.

The market for the delivery of Internet-based services through wireless telephones is rapidly evolving, and Phone.com may not be able to adequately address this market.

The market for the delivery of Internet-based services through wireless telephones is rapidly evolving and is characterized by an increasing number of market entrants who have introduced or developed, or are in the process of introducing or developing, products that facilitate the delivery of Internet- based services through wireless telephones. As a result, the life cycle of Phone.com's products is difficult to estimate. Phone.com may not be able to develop and introduce new products, services and enhancements that respond to technological changes or evolving industry standards on a timely basis, in which case its business would suffer. In addition,

19

Phone.com cannot predict the rate of adoption by wireless subscribers of these services or the price they will be willing to pay for these services. As a result, it is extremely difficult to predict the pricing of these services and the future size and growth rate of this market.

Phone.com's network operator customers face implementation and support challenges in introducing Internet-based services via wireless telephones, which may slow their rate of adoption or implementation of the services Phone.com's products enable. Historically, network operators have been relatively slow to implement new complex services such as Internet-based services. In addition, network operators may encounter greater customer service demands to support Internet-based services via wireless telephones than they do for their traditional voice services. Phone.com has limited or no control over the pace at which network operators implement these new services. The failure of network operators to introduce and support services utilizing Phone.com's products in a timely and effective manner could harm its business.

Until recently, Phone.com has relied on sales to a small number of customers, and the failure to retain these customers or add new customers may harm its business.

To date, a significant portion of Phone.com's revenues in any particular period has been attributable to a limited number of customers, comprised primarily of network operators and wireless telephone manufacturers. Phone.com believes that it will continue to depend upon a limited number of customers for a significant portion of its revenues for each quarter for the foreseeable future. Any failure by Phone.com to capture a significant share of those customers could materially harm its business. For example, during the fiscal year ended June 30, 1999, AT&T Wireless Services accounted for approximately 17% of our total revenues, and DDI Corporation accounted for approximately 14% of our total revenues. For the year ended June 30, 2000 AT&T Wireless Services and DDI Corporation accounted for 6% and 18%, respectively, of our total revenues. The foregoing calculations are based on revenues derived from direct and indirect sales to these customers.

If wireless telephones are not widely adopted for mobile delivery of Internet- based services, Phone.com's business could suffer.

Phone.com has focused its efforts on mass-market wireless telephones as the principal means of delivery of Internet-based services using its products. If wireless telephones are not widely adopted for mobile delivery of Internet- based services, Phone.com's business would suffer materially. Mobile individuals currently use many competing products, such as portable computers, to remotely access the Internet and e-mail. These products generally are designed for the visual presentation of data, while wireless telephones historically have been limited in this regard. In addition, the development and proliferation of many types of competing products capable of the mobile delivery of Internet-based services in a rapidly evolving industry represents a significant risk to adoption of wireless telephones as the dominant mobile device for accessing Internet-based services. If mobile individuals do not adopt wireless telephones as a means of accessing Internet-based services, Phone.com's business would suffer.

If widespread integration of browser technology does not occur in wireless telephones, Phone.com's business could suffer.

Because Phone.com's current UP.Link Server Suite and related server-based software offers enhanced features and functionality that are not currently covered by the specifications promulgated by the WAP Forum, subscribers currently must use UP.Browser-enabled wireless telephones in order to fully utilize these features and functionality. Additionally, Phone.com expects that future versions of its UP.Link Server Suite and related server-based software will offer features and functionality that are compatible with the specifications promulgated by the WAP Forum. Phone.com's business could suffer materially if widespread integration of UP.Browser or WAP-compliant third- party browser software in wireless telephones does not occur. All of Phone.com's agreements with wireless telephone manufacturers are nonexclusive, so they may choose to embed a browser other than Phone.com's in their wireless telephones. Phone.com may not succeed in maintaining and developing relationships with telephone manufacturers, and any arrangements may be terminated early or not renewed at

20

expiration. In addition, wireless telephone manufacturers may not produce products using UP.Browser in a timely manner and in sufficient quantities, if at all.

Phone.com's strategy for the MyPhone business model is subject to uncertainties, and Phone.com may not be able to generate sufficient revenues to achieve profitability.

In September 1999, Phone.com announced its MyPhone service. Phone.com offers MyPhone as an OEM service to enable network operators to create branded mobile Internet portals for their subscribers, and Phone.com does not currently intend to develop its own branded portal site. Phone.com also offers MyPhone as software products that network operators can license from Phone.com and host themselves. Phone.com has limited experience in developing mobile internet portals, and it may not be successful in executing its business strategy for the MyPhone service and products. The success of MyPhone will depend on a number of factors, including the successful transition from offering MyPhone as a hosted service to also offering MyPhone products, the adoption of MyPhone network operators, Phone.com's ability to provide compelling applications and services through MyPhone, and the acceptance by end users of the MyPhone service from network operators. Developing these capabilities and commercializing the product offering will require Phone.com to incur significant additional expenses, including costs relating to operating the portal, as well as sales and marketing and research and development expenses. Phone.com expects to incur these costs and expenses in advance of generating revenues from the services and products. Furthermore, Phone.com's business model for MyPhone is new and evolving. Even if Phone.com is successful in executing this strategy, it cannot be certain that its business model for the MyPhone service and products will result in sufficient revenue to achieve profitability.

The market for Phone.com's products and services is highly competitive.

The market for Phone.com's products and services is becoming increasingly competitive. The widespread adoption of open industry standards such as the WAP specifications may make it easier for new market entrants and existing competitors to introduce products that compete with Phone.com's software products. In addition, a number of Phone.com's competitors, including Nokia, have announced or are expected to announce enhanced features and functionality as proprietary extensions to the WAP protocol. Furthermore, some of Phone.com's competitors, such as NTT, have introduced or may introduce services based on proprietary wireless protocols that are not compliant with the WAP specifications.

Phone.com expects that it will compete primarily on the basis of price, time to market, functionality, quality and breadth of product and service offerings. Phone.com's current and potential competitors include the following:

. Wireless equipment manufacturers, such as Ericsson and Nokia;

. Microsoft;

. Wireless Knowledge, a joint venture of Microsoft and Qualcomm, as well as a similar European joint venture of Microsoft and Ericsson;

. Systems integrators, such as CMG plc, and software companies, such as Oracle Corporation and iPlanet, a Sun/Netscape alliance;

. Wireless network operators, such as NTT DoCoMo;

. providers of Internet software applications and content, electronic messaging applications and personal information management software solutions; and

. providers of unified messaging products and services, such as Comverse and Critical Path.

In particular, Microsoft Corporation has announced its intention to introduce products and services that may compete directly with Phone.com's UP.Link, UP.Browser and UP.Application products. In addition, Microsoft has announced that it intends to enable its Windows CE operating system to run on wireless handheld devices, including wireless telephones. Microsoft has announced its own browser, called Mobile Explorer, for these

21

devices. Furthermore, Nokia is marketing a WAP server to corporate customers and content providers. This WAP server is designed to enable wireless telephone subscribers to directly access applications and services provided by these customers, rather than through gateways provided by network operators' WAP servers. If Nokia's WAP server is widely adopted by corporate customers and content providers, it could undermine the need for network operators to purchase WAP servers. Many of Phone.com's existing competitors, as well as potential competitors, have substantially greater financial, technical, marketing and distribution resources than Phone.com does.

As Phone.com enters new markets and introduces new services, such as the MyPhone products and services, it will face additional competitors. As Phone.com enters the unified messaging market, it will face competition from established voicemail providers such as Comverse, and Internet-based unified messaging providers such as Critical Path. In the Portal Framework market, a number of companies have introduced products and services relating to mobile portals that compete with Phone.com's MyPhone service. These existing and potential competitors may include telecommunications companies such as Lucent Technologies, traditional Internet portals, Internet infrastructure software companies and several private mobile Internet portal companies. Phone.com's FoneSync synchronization product will face competition from Motorola's TrueSync product, and product from Puma, as well as from emerging synchronization companies such as Fusion One.

Phone.com's software products may contain defects or errors, and shipments of Phone.com's software may be delayed.

The software Phone.com develops is complex and must meet the stringent technical requirements of its customers. Phone.com must develop its products quickly to keep pace with the rapidly changing Internet software and telecommunications markets. Software products and services as complex as Phone.com's are likely to contain undetected errors or defects, especially when first introduced or when new versions are released. Phone.com has in the past experienced delays in releasing some versions of its products until software problems were corrected. Phone.com's products may not be free from errors or defects after commercial shipments have begun, which could result in the rejection of its products and damage to its reputation, as well as lost revenues, diverted development resources, and increased service and warranty costs, any of which could harm Phone.com's business.

Phone.com depends on recruiting and retaining key management and technical personnel with telecommunications and Internet software experience.

Because of the technical nature of Phone.com's products and the dynamic market in which Phone.com competes, its performance depends on attracting and retaining key employees. In particular, Phone.com's future success depends in part on the continued services of each of its executive officers. Competition for qualified personnel in the telecommunications and Internet software industries is intense, and finding qualified personnel with experience in both industries is even more difficult. Phone.com believes that there are only a limited number of persons with the requisite skills to serve in many key positions, and it is becoming increasingly difficult to hire and retain these persons. Competitors and others have in the past, and may in the future, attempt to recruit Phone.com's employees.

Phone.com may fail to support its anticipated growth in operations.

To succeed in the implementation of its business strategy, Phone.com must rapidly execute its sales strategy and further develop products and expand service capabilities, while managing anticipated growth by implementing effective planning and operating processes. If Phone.com fails to manage its growth effectively, its business could suffer materially. To manage anticipated growth, Phone.com must:

. continue to implement and improve its operational, financial and management information systems; for example, Phone.com is currently in the process of implementing Oracle financial software;

. hire, train and retain additional qualified personnel;

. continue to expand and upgrade core technologies;

22

. effectively manage multiple relationships with various network operators, wireless telephone manufacturers, content providers, applications developers and other third parties; and

. successfully integrate the businesses of its acquired companies.

Phone.com's systems, procedures and controls may not be adequate to support its operations, and its management may not be able to achieve the rapid execution necessary to exploit the market for its products and services.

Phone.com's success, particularly in international markets, depends in part on its ability to maintain and expand its distribution channels.

Phone.com's success depends in part on its ability to increase sales of its products and services through value-added resellers and systems integrators and to expand its indirect distribution channels. If Phone.com is unable to maintain the relationships that it has with its existing distribution partners, increase revenues derived from sales through its indirect distribution channels, or increase the number of distribution partners with whom it has relationships, then Phone.com may not be able to increase its revenues or achieve profitability.

Phone.com expects that many network operators in international markets will require that Phone.com's products and support services be supplied through value-added resellers and systems integrators. Thus, Phone.com expects that a significant portion of international sales will be made through value-added resellers and systems integrators, and the success of its international operations will depend on its ability to maintain productive relationships with value-added resellers and systems integrators.

In addition, Phone.com's agreements with its distribution partners generally do not restrict the sale by them of products and services that are competitive with Phone.com's products and services, and each of Phone.com's partners generally can cease marketing our products and services at their option and, in some circumstances, with little or no notice or penalty.

Phone.com depends on others to provide content and develop applications for wireless telephones.

In order to increase the value to customers of Phone.com's product platform and encourage subscriber demand for Internet-based services via wireless telephones, Phone.com must successfully promote the development of Internet- based applications and content for this market. If content providers and application developers fail to create sufficient applications and content for Internet-based services via wireless telephones, its business could suffer materially. Phone.com's success in motivating content providers and application developers to create and support content and applications that subscribers find useful and compelling will depend, in part, on its ability to develop a customer base of network operators and wireless telephone manufacturers large enough to justify significant and continued investments in these endeavors.

If Phone.com is unable to integrate its products with third-party technology, such as network operators' systems, its business may suffer.

Phone.com products are integrated with network operators' systems and wireless telephones. If Phone.com is unable to integrate its platform products with these third-party technologies, its business could suffer materially. For example, if, as a result of technology enhancements or upgrades of these systems or telephones, Phone.com is unable to integrate its products with these systems or telephones, Phone.com could be required to redesign its software products. Moreover, many network operators use legacy, or custom- made, systems for their general network management software. Legacy systems and certain custom-made systems are typically very difficult to integrate with new server software such as Phone.com's UP.Link Server Suite. Phone.com may not be able to redesign its products or develop redesigned products that achieve market acceptance.

An interruption in the supply of software that Phone.com licenses from third parties could cause a decline in product sales.

Phone.com licenses technology that is incorporated into its products from third parties, such as RSA Data Security, Inc. and other companies. Any significant interruption in the supply of any licensed software could cause a decline in product sales, unless and until Phone.com is able to replace the functionality provided by this licensed software. Phone.com also depends on these third parties to deliver and support reliable products, enhance their current products, develop new products on a timely and cost-effective basis, and respond to emerging industry standards and other technological changes. The failure of these third parties to meet these criteria could materially harm Phone.com's business.

Phone.com may be unable to adequately protect its proprietary rights.

Phone.com's success depends significantly on its ability to protect its proprietary rights to the technologies used in Phone.com's products. If Phone.com is not adequately protected, its competitors could use the intellectual property that Phone.com has developed to enhance their products and services, which could harm Phone.com's business. Phone.com relies on patent protection, as well as a combination of copyright and trademark laws, trade secrets, confidentiality provisions and other contractual provisions, to protect its proprietary rights, but these legal means afford only limited protection.

Phone.com may be sued by third parties for infringement of their proprietary rights.

The telecommunications and Internet software industries are characterized by the existence of a large number of patents and frequent litigation based on allegations of patent infringement or other violations of intellectual property rights. As the number of entrants into Phone.com's market increases, the possibility of an intellectual property claim against Phone.com grows. Any intellectual property claims, with or without merit, could be time-consuming and expensive to litigate or settle and could divert management attention from administering Phone.com's core business.

In April 2000, Phone.com filed a lawsuit against Geoworks Corporation in the U.S. District Court in San Francisco, California, alleging, and seeking a court order declaring, that U.S. Patent No. 5,327,529, assigned to Geoworks is not infringed by Phone.com and that the patent is also invalid and unenforceable. Phone.com took this action in response to Geoworks' attempt to require industry participants to obtain licenses under the Geoworks patent. On June 15, 2000, Geoworks filed an answer to Phone.com's complaint and asserted a counterclaim against Phone.com alleging that Phone.com infringes the patent and seeking various forms of relief. Phone.com denies Geoworks' allegations and while Phone.com intends to pursue its position vigorously, the outcome of any litigation is uncertain, and Phone.com may not prevail. Additionally, we may incur substantial expenses in defending against this claim. Should Phone.com be found to infringe the Geoworks patent, Phone.com may be liable for potential monetary damages, and could be required to obtain a license from Geoworks. If Phone.com was unable to obtain a license on commercially reasonable terms, it may not be able to proceed with development and sale of some of its products.

International sales of products is an important part of Phone.com's strategy, and this expansion carries specific risks.

International sales of products and services accounted for 73% of Phone.com's total revenues for the year ended June 30, 2000. Phone.com expects international sales to continue to account for a significant portion of its revenues, although the percentage of Phone.com's total revenues derived from international sales may vary. Risks inherent in Phone.com's international business activities include business, economic, political and legal risks. See "Phone.com's Management's Discussion and Analysis of Financial Condition and Results of Operations-Overview."

24

Undetected Year 2000 problems could potentially harm Phone.com's business.

Although the date is now past January 1, 2000 and Phone.com has not experienced any material adverse impact from the transition to the Year 2000, Phone.com cannot provide assurance that its suppliers and customers have not been affected in a manner that is not yet apparent. In addition, certain computer programs that were date sensitive to the Year 2000 may experience difficulties with future dates even though they have not experienced difficulties to date.

Phone.com's stock price, like that of many companies in the Internet and telecommunications software industries, may be volatile.

Since Phone.com's initial public offering in June 1999, its stock price has experienced significant volatility. Phone.com expects that the market price of its common stock also will fluctuate in the future as a result of variations in its quarterly operating results. These fluctuations may be exaggerated if the trading volume of Phone.com's common stock is low. In addition, due to the technology-intensive and emerging nature of Phone.com's business, the market price of its common stock may rise and fall in response to:

. announcements of technological or competitive developments;

. acquisitions or strategic alliances by Phone.com or its competitors;

. the gain or loss of a significant customer or order; and

. changes in estimates of Phone.com's financial performance or changes in recommendations by securities analysts.

Additionally, the market price of Software.com is subject to many of the same risks listed above. Because of Phone.com's pending merger with of Software.com, fluctuations in Software.com's stock price can increase the volatility in the market price of Phone.com's common stock.

Phone.com's stock price may be volatile, exposing it to expensive and time- consuming securities class action litigation.

The stock market in general, and the stock prices of Internet-related companies in particular, have recently experienced extreme volatility, which has often been unrelated to the operating performance of any particular company or companies. If market or industry-based fluctuations continue, Phone.com's stock price could decline below current levels or the initial public offering price regardless of its actual operating performance. Furthermore, the historical trading volume of Phone.com's stock is not indicative of any future trading volume of Phone.com's stock because a substantial portion of shares were not eligible for sale until recently. Therefore, if a large number of shares of Phone.com's stock are sold in a short period of time, Phone.com's stock price will decline. In the past, securities class action litigation has often been brought against companies following periods of volatility in their stock prices. Phone.com may in the future be the target of similar litigation. Securities litigation could result in substantial costs and divert Phone.com's management's time and resources, which could harm its business, financial condition, and operating results.

Phone.com's certificate of incorporation, bylaws, rights agreement and Delaware law contain provisions that could discourage a takeover.

On August 8, 2000, in connection with Phone.com's pending merger with Software.com, Phone.com's board of directors declared a dividend distribution of one right for each share of Phone.com's common stock outstanding on August 18, 2000. The rights are exercisable for a series of Phone.com's preferred stock under certain circumstances as specified in Phone.com's rights agreement dated August 8, 2000. The potential exercise of rights under the rights agreement could discourage, delay or prevent a merger or acquisition that a stockholder may consider favorable. Additionally, provisions of Phone.com's certificate of incorporation and bylaws and Delaware law may discourage, delay or prevent a merger. These provisions include the following:

. establishing a classified board in which only a portion of the total board members will be elected at each annual meeting;

25

. authorizing the board to issue preferred stock;

. prohibiting cumulative voting in the election of directors;

. limiting the persons who may call special meetings of stockholders;

. prohibiting stockholder action by written consent; and

. establishing advance notice requirements for nominations for election of the board of directors or for proposing matters that can be acted on by stockholders at stockholder meetings.

Risks Relating to the Business and Operations of Software.com

Software.com's future revenues are unpredictable and it expects its quarterly operating results to fluctuate.

Software.com may fail to accurately forecast its revenues in any given period as a result of its limited operating history, the emerging nature of the markets in which it competes and its reliance on a small number of products and large customers. Software.com's revenues could fall short of its expectations if it experiences delays in signing new customer accounts or cancellation of one or more current or new customer accounts. A number of factors are likely to cause fluctuations in Software.com's operating results, including:

. the volume and timing of mailbox activation by Software.com's InterMail Mx customers;

. the length of Software.com's sales and product deployment cycles for Software.com's InterMail products;

. Software.com's ability to attract and retain customers in new markets, including Europe and Asia;

. Software.com's continuing dependence on the InterMail line of products and related services for substantially all of its revenues;

. Software.com's dependence on a small number of large customers;

. Software.com's dependence on continued growth of the service provider market;

. any delays in Software.com's introduction of new products or enhancements;

. the amount and timing of operating costs and capital expenditures relating to expansion of Software.com's operations;

. the announcement or introduction of new or enhanced products or services by Software.com's competitors;

. adverse customer reaction to technical difficulties or "bugs" in Software.com's software;

. the growth rate and performance of the Internet in general and of Internet communications in particular;

. the growth rate and performance of wireless networks in general and of wireless communications in particular;

. the volume of sales by Software.com's distribution partners and resellers;

. Software.com's pricing policies and those of its competitors; and

. the increase in Software.com's cost to resell, or its customers' cost to buy or the unavailability of, the Oracle 8i database which is currently necessary to use Software.com's InterMail Mx product and any related price concessions on Software.com's InterMail Mx product that its customers demand as a result.

Due to the foregoing factors, Software.com's quarterly operating results have fluctuated significantly and it expects that future operating results will be subject to similar fluctuations. Software.com's revenue from large- scale installations of its software depends heavily on the customers' timing of deployment of its software, the migration of their installed base of users to its software platform, and the rate of growth of their customer base. Accordingly, a delay in a deployment past the end of a particular quarter could negatively impact Software.com's results of operations for that quarter. It is possible that in future quarters Software.com's operating results could fall below the expectations of public market analysts or investors. In this event, the price of Software.com's common stock may fall.

26

Software.com plans to significantly increase its operating expenses to expand its international sales and marketing operations and fund greater levels of research and development. Software.com's operating expenses, which include sales and marketing, research and development, and general and administrative expenses, are based on expectations of future revenues and are relatively fixed in the short term. If revenues fall below Software.com's expectations and it is not able to quickly reduce its spending in response, its business, financial condition, and operating results will suffer. Accordingly, period-to-period comparisons of Software.com's operating results are not a good indication of its future performance. It is possible that Software.com's operating results in some quarters will not meet the expectations of stock market analysts and investors.

Variations in the time it takes to sell, deploy and activate mailboxes using Software.com's InterMail Mx product may cause fluctuations in Software.com's operating results.

Variations in the length of Software.com's sales and deployment cycles for InterMail Mx could cause its revenue, and thus its business, financial condition and operating results, to fluctuate widely from period to period. Software.com's customers generally take a long time to evaluate its InterMail Mx product, and many people are involved in the evaluation process. Software.com expends significant resources educating and providing information to its prospective customers regarding the use and benefits of InterMail Mx. Additionally, at present, in order to deploy Software.com's InterMail Mx product, a customer must have a license to use an Oracle 8i database. Software.com's customers' cost for purchasing an Oracle 8i database, whether from Software.com or directly from Oracle, has increased and may cause potential customers to decide not to buy Software.com's InterMail Mx product. If this happens, Software.com may be forced to absorb some of the costs of the increase in order to sell the InterMail Mx product. In either case, unless Software.com is able to identify and implement a suitable alternative to the Oracle database, Software.com's revenues from its InterMail Mx product would decrease. Although Software.com is actively evaluating alternative databases, there can be no assurance that it will be able to substitute a new database for Oracle in a timely and cost-effective manner. Even if a customer decides to purchase Software.com's InterMail Mx product, Software.com's customers tend to integrate InterMail Mx into their existing systems slowly and deliberately. The timing of the deployment depends upon:

. the efforts of Software.com's professional services staff;

. the geographic disbursement of the customer's hardware;

. the complexity of the customer's network and the resulting degree of hardware configuration necessary to deploy InterMail Mx on their system;

. the internal technical capabilities of the customer;

. the customer's budgetary constraints; and

. the stability and sophistication of the customer's current messaging system.

Because of the number of factors influencing the sales and deployment processes, the period between Software.com's initial contact with a new customer and the time when Software.com begins to recognize revenue from that customer varies widely in length. Software.com's sales cycles for InterMail Mx typically range from six months to a year, and its software deployment cycles typically range from three to six months thereafter, although occasionally these cycles can be much longer. During these cycles, Software.com typically commits substantial resources in advance of receiving any software license revenue.

In addition, the amount of software license revenue that Software.com is able to recognize in any given period depends on how quickly Software.com's customers activate new mailboxes and report the activation of those new mailboxes to Software.com. Under Software.com's InterMail Mx license agreements, Software.com's customers typically pay it a fee for each new user account, or "mailbox," they activate using InterMail Mx. Software.com recognizes software license revenue from these agreements when its customer reports mailbox activations to it or Software.com otherwise learns of such activations. Customers typically report activations on a quarterly basis after they have completed a deployment of InterMail Mx. Because Software.com charges its customers only for activating "new" mailboxes, a customer can reassign a lost subscriber's mailbox to a new subscriber without having to pay Software.com a fee. Software.com cannot control how quickly its customers

27

activate new mailboxes. The primary factors affecting the timing are the ability of Software.com's customers to retain subscribers and grow their subscriber bases by attracting end users to their online services, and their willingness to promote InterMail Mx messaging services with their subscribers. Mailbox activations and the associated revenue may be concentrated in a particular quarter and, as a result, Software.com's revenue for a particular quarter is not a good indication of its future revenue. Software.com's revenues may fluctuate widely from period to period depending on the timing of its customers' activation of new mailboxes, and any delay in or failure by its customers to activate new mailboxes will harm its business, financial condition, and operating results.

In addition, Software.com bases its quarterly revenue projections, in part, upon its expectations of how many mailboxes its InterMail Mx customers will activate in that quarter. Because the timing of mailbox activation is outside of Software.com's control, it is often difficult for Software.com to make accurate forecasts. If Software.com's expectations, and thus its revenue projections, are not accurate for a particular quarter, its actual operating results for that quarter could fall below the expectations of analysts and investors.

Because Software.com has a limited operating history, it may be difficult for you to evaluate Software.com's business and prospects.

Software.com has only a limited operating history, which makes it difficult for investors to predict its future operating performance. You should consider the risks, expenses, and difficulties that Software.com may encounter as a young company in a rapidly evolving market. These risks include Software.com's ability to:

. expand its sales and marketing activities;

. expand its customer base;

. develop and introduce new products and services;

. identify and integrate acquisitions; and

. compete effectively.

Software.com cannot be certain that its business strategy will be successful or that it will successfully address these risks.

Software.com has a history of losses and it may not be able to achieve or sustain profitability in the future.

Software.com has a history of losses and may not be able to achieve or sustain profitability in the future. Software.com has historically invested heavily in its sales and marketing efforts and in technology research and development. Software.com expects to continue to spend substantial resources on developing and introducing new software products and on expanding its sales and marketing activities, particularly in Europe, Japan and Asia Pacific. As a result, Software.com needs to generate significant revenues to achieve and maintain profitability. Software.com expects that its sales and marketing expenses, research and development expenses, and general and administrative expenses will continue to increase in absolute dollars and may increase as percentages of revenues. In addition, any amortization of goodwill or other intangible assets, or other charges resulting from the costs of acquisitions could significantly impact its business, financial condition, and operating results.

As of June 30, 2000, Software.com had an accumulated deficit of approximately $60.1 million. Although Software.com's revenues have grown significantly in recent quarters, it may not be able to sustain these growth rates or obtain sufficient revenues to achieve or maintain profitability.

Software.com depends on a small number of customers for most of its revenues, and its business, financial condition, and operating results could be harmed by a decline or delay in revenue from these customers.

Software.com has generated a significant portion of its revenues from a limited number of customers. Software.com expects that a small number of customers will continue to account for a significant portion of

28

revenues for the foreseeable future. Software.com's target market is made up only of service providers, which constitute only a small portion of all users of messaging and directory solutions. As a result, if Software.com loses a major customer, or if there is a decline in usage, or if there is a downturn in the service provider industry, Software.com's business, financial condition, and operating results will suffer. Software.com cannot be certain that customers that have accounted for significant revenues in past periods, individually or as a group, will continue to generate revenues for Software.com in any future period.

Software.com must overcome significant and increasing competition in order to continue its growth.

The market for Internet standards-based messaging and infrastructure products and services is intensely competitive, and Software.com expects it to become increasingly so in the future. Software.com competes in its core service provider market with many software providers and, in some instances, with outsourced messaging providers who have either internally developed or acquired their own messaging software. Software.com also competes, principally on the basis of performance, features and price, against messaging solutions based on public domain software code that is developed and enhanced internally by service providers. Software.com competes to a more limited extent with providers of messaging applications designed for the enterprise market.

Software.com's current software competitors in the service provider market include iPlanet E-Commerce Solutions (a Sun/Netscape Alliance) and Isocor, which was recently acquired by Critical Path. Software.com also indirectly competes with Critical Path when it offers outsourced messaging to the service provider market and with Microsoft, whose current messaging product was developed for the enterprise market but is sold to some service providers. In addition, with Software.com's release of a highly scalable LDAP directory with InterMail Mx, Software.com has become more direct competitors with Novell's NDS technology and Microsoft's Active Directory product, to the extent that these products are marketed to service providers. Software.com believes that competition will intensify as its current competitors increase the sophistication of their offerings and as new market participants, including additional providers of outsourced messaging services enter the market. Many of Software.com's current and future competitors have longer operating histories, larger installed customer bases, greater brand recognition, and significantly greater financial, marketing and other resources than Software.com does. In addition, these competitors may benefit from existing strategic and other relationships with each other or with Software.com's current customers. Software.com must respond quickly and effectively to the new products, services, and enhancements offered by its competitors in order to continue its growth.

Microsoft and other competitors possess many competitive advantages over Software.com that present risks to the sales of Software.com's products.

Microsoft, among other software providers, is well positioned to become increasingly competitive in Software.com's service provider messaging market. Software.com believes that Microsoft is currently in the process of developing electronic messaging software to compete more directly in its core service provider market. Because of its dominance in other software markets, Microsoft has many competitive advantages over Software.com. For example, Microsoft could incorporate electronic messaging technology into its Web browser software, its client operating system or email interface, or its server software offerings, possibly at no additional cost to service providers or end users. In addition, Microsoft may promote technologies and standards that are not compatible with Software.com's technology, or that are less compatible with Software.com's technology than competitive products offered by Microsoft. Software.com believes that Microsoft's increasing presence in the electronic messaging software industry will dramatically increase competitive pressure in the market, leading to increased pricing pressure and longer sales cycles. These competitive pressures may force Software.com to reduce the prices of its products, and may also materially reduce its market share.

In addition to the existing competitors listed above, voicemail solutions providers could be formidable competitors in the unified communications infrastructure software and Internet voicemail markets because of their existing presences in service providers and ownership of technologies for the conversion of voice to data. If Software.com is unable to compete effectively with Microsoft, existing voicemail solution providers, or its other existing or emerging competitors, its business, financial condition, and operating results will suffer.

29

Software.com's InterMail Kx product may interfere with sales of its other products.

Competition from InterMail Kx has had a negative effect on Software.com's sales of Post.Office and could have a negative impact on its sales of InterMail Mx, or the prices it could charge for these products. Software.com's InterMail Kx product was introduced in March of 1999 and overlaps to some extent with its Post.Office product as both products are targeted at small and medium size service providers worldwide. Software.com currently has several licenses for its Post.Office product with service providers that have more than 25,000 subscribers and Software.com has licensed its InterMail Mx product to service providers with fewer than 250,000 subscribers. Accordingly, InterMail Kx may compete to some extent with Software.com's other products. Software.com may also divert sales and marketing resources from Post.Office in order to successfully promote and develop InterMail Kx. This diversion of resources could have a further negative effect on Software.com's sales of Post.Office. If Software.com's revenues from InterMail Kx are not sufficient to compensate for the effect of any decrease in sales or prices of its other products, its business, financial condition, and operating results will suffer.

Software.com's acquisition strategy could cause financial or operational problems.

Software.com's success depends on its ability to continually enhance and broaden its product offerings in response to changing technologies, customer demands, and competitive pressures. To this end, Software.com may acquire new and complementary businesses, products, or technologies, instead of developing them itself. Software.com does not know if it will be able to complete any acquisitions or that it will be able to successfully integrate any acquired business, operate them profitably, or retain their key employees. For example, Software.com completed the acquisitions of Mobility.Net Corporation, in April 1999, of Telarc, in October 1999, and of bCandid, in June 2000, and continue to integrate these companies' products and personnel into Software.com's organization. Software.com completed the acquisition of AtMobile in April 2000. AtMobile is a substantially larger organization than either Mobility.Net or Telarc and therefore will present greater challenges in terms of integration of products and employees. Integrating AtMobile or any other newly acquired business, product or technology could be expensive and time- consuming, could disrupt Software.com's ongoing business, and could distract Software.com's management. Software.com may face competition for acquisition targets from larger and more established companies with greater financial resources. In addition, in order to finance any acquisitions, Software.com might need to raise additional funds through public or private financings. In that event, Software.com could be forced to obtain equity or debt financing on terms that are not favorable to it and, in the case of equity financing, that results in dilution to Software.com's stockholders. If Software.com is unable to integrate AtMobile or any other newly acquired entities or technologies effectively, Software.com's business, financial condition, and operating results would suffer. In addition, any amortization of goodwill or other assets, or other charges resulting from the costs of acquisitions could harm Software.com's business, financial condition, and operating results.

Software.com's expanding international operations are subject to significant uncertainties in addition to those it faces in domestic markets.

Revenues attributable to customers outside of North America accounted for approximately 45% of Software.com's total revenues for the three months ended June 30, 2000. If Software.com's revenues from international operations, and particularly from its operations in the countries and regions on which Software.com has focused its spending, do not exceed the expense of establishing and maintaining these operations, its business, financial condition, and operating results will suffer. Software.com continues to invest significant financial and managerial resources to expand its sales and marketing operations in international markets, and it must continue to do so for the foreseeable future in order to succeed in these markets. In particular, Software.com is making significant expenditures on expansion in Europe and Asia, including the translation of its products for use in these regions, and it expects these expenditures to continue or increase. Software.com is expending the most resources in the countries and regions that it thinks will be the most receptive markets for its products. Software.com has only limited experience in international operations, and it may not be able to capitalize on its

30

investment in these markets. In this regard, Software.com faces certain risks inherent in conducting business internationally, including:

. fluctuations in currency exchange rates;

. problems caused by the ongoing conversion of various European currencies into a single currency, the Euro;

. any imposition of currency exchange controls;

. unexpected changes in regulatory requirements applicable to the Internet or Software.com's business;

. difficulties and costs of staffing and managing international operations;

. differing technology standards;

. difficulties in collecting accounts receivable and longer collection periods;

. seasonal variations in customer buying patterns or electronic messaging usage;

. political instability or economic downturns;

. potentially adverse tax consequences; and

. reduced protection for intellectual property rights in certain countries.

Any of these factors could harm Software.com's international operations and, consequently, its business, financial condition, and operating results.

The loss of any of Software.com's senior management or key personnel could harm its business, financial condition, and operating results.

Software.com's success depends on the skills, experience and performance of its senior management and certain other key personnel, some of whom have worked together for only a short period of time. With the exception of certain key personnel who have joined Software.com in connection with acquisitions, Software.com does not have employment agreements with any of its senior management, and their employment is at will. The loss of the services of any of Software.com's senior management or other key personnel could harm its business, financial condition, and operating results.

If Software.com is unable to attract and retain highly skilled employees, its financial and operational results may suffer.

Software.com's success depends on its ability to recruit, integrate, retain, and motivate highly skilled sales and marketing, engineering, and quality assurance personnel. In particular, Software.com's ability to attract and retain qualified sales management personnel is critical to the success of its planned expansion in Europe and Asia. Competition for these people in the Internet messaging industry is intense, and Software.com may not be able to successfully recruit, train, or retain qualified personnel. If Software.com fails to retain and recruit necessary sales and marketing, engineering, and quality assurance personnel, its ability to obtain new customers, develop new products and provide acceptable levels of customer service could suffer, and this could harm its business, financial condition, and operating results.

Software.com must adapt to rapid changes in technology and customer preferences in order to remain competitive.

The Internet messaging industry is characterized by rapidly changing technology, changes in customer and end user requirements and preferences, and evolving industry standards and practices that could render its software products obsolete. Software.com's success depends on its ability to enhance its existing messaging and directory platform and products on a timely basis and to develop new products that address the increasingly sophisticated and varied needs of its customers and their end users. Software.com must accurately forecast the features and functionality required by its target customers and end users in order to continually improve its products. For example, in response to customer and end user demand, Software.com has recently developed for

31

some of its products a voicemail feature based on Internet standards that govern data transmission and receipt, known as Internet Protocol or "IP." In addition, in response to the rapid development of opportunities in the wireless sector, Software.com is aggressively pursuing the development and/or acquisition of key technologies required by service providers in the wireless sector. The development of proprietary technology and product enhancements has required, and will continue to require, substantial expenditures and lead- time, and Software.com may not always be able to keep pace with the latest technological developments. If Software.com cannot, for technical, legal, financial, or other reasons, adapt its products to changing customer or end user requirements or industry standards in a cost-effective and timely fashion, or if any new product, enhancement, or feature, including IP voicemail or the wireless messaging products and technologies acquired in the Telarc acquisition and the AtMobile.com acquisition is not favorably received and accepted by customers and end users, Software.com's business, financial condition, and operating results will suffer.

Software.com's software products may have unknown defects, which could harm its reputation or impede market acceptance of its products.

Despite testing by Software.com, defects have in the past and may in the future occur in its software. Complex software like Software.com's is difficult to integrate with customers' existing systems and often contains errors or defects, particularly when first introduced or when new versions or enhancements are released. Although Software.com conducts extensive testing, it may not discover software defects that affect its current or new products, including new releases or editions of its InterMail products, the wireless messaging products acquired in the Telarc acquisition or the wireless products intended to be developed as a result of the AtMobile acquisition, until after they are sold. Software.com also experiences difficulty in deploying software at Software.com's customer's sites due to its complex nature. Any defect in other software or hardware with which Software.com's software interacts could be mistakenly attributed to Software.com's software by its customers or their end users. These defects or perceptions of defects could cause Software.com's customers and their end users to experience service interruptions. Because Software.com's customers depend on its software to provide critical services to their end users, any service interruptions could damage Software.com's reputation or increase its product development costs, divert its product development resources, cause it to lose revenue, or delay market acceptance of its products, any of which could harm its business, financial condition, and operating results.

The rapid growth of Software.com's operations could strain its resources and harm its business, financial condition, and operating results.

Software.com's recent growth has placed and will continue to place a significant strain on its management systems, infrastructure, and resources. Software.com is increasing the scope of its operations and its customer base domestically and internationally, and it has recently increased its headcount substantially. From December 31, 1997 to July 31, 2000 Software.com's total number of employees increased from 144 to 516. Software.com expects that it will need to continue to improve its financial and managerial controls and reporting systems and procedures, and will need to continue to expand, train, and manage its workforce worldwide. Software.com expects that it will be required to manage an increasing number of relationships with various customers and other third parties. Software.com's ability to successfully offer products and services and implement its business plan in a rapidly evolving market requires an effective planning and management process. Any failure to expand any of the foregoing areas efficiently and effectively could harm Software.com's business, financial condition and operating results. In addition, there can be no assurance that Software.com's business will continue to grow at historical rates.

Software.com's business depends on continued growth in use and improvement of the Internet and its customers' ability to operate their systems effectively.

The infrastructure, products, and services necessary to maintain and expand the Internet may not be developed, and the Internet may not continue to be a viable medium for secure and reliable personal and business communication, in which case its business, financial condition, and operating results would be harmed. Because Software.com is in the business of providing Internet infrastructure applications, its future success depends on

32

the continued expansion of, and reliance of consumers and businesses on, the Internet for communications and other services. The Internet may not be able to support an increased number of users or an increase in the volume of data transmitted over it. As a result, the performance or reliability of the Internet in response to increased demands will require timely improvement of the high speed modems and other communications equipment that form the Internet's infrastructure. The Internet has already experienced temporary outages and delays as a result of damage to portions of its infrastructure. The effectiveness of the Internet may also decline due to delays in the development or adoption of new technical standards and protocols designed to support increased levels of activity and due to the transmission of computer viruses.

In addition to problems that may affect the Internet as a whole, Software.com's customers have in the past experienced some interruptions in providing their Internet-related services, including services related to Software.com's software products. Software.com believes that these interruptions will continue to occur from time to time. Software.com's revenues depend substantially upon the number of end-users who use the services provided by its customers. Software.com's business may suffer if its customers experience frequent or long system interruptions that result in the unavailability or reduced performance of their systems or networks or reduce their ability to provide services to their end users.

The market for wireless communications and the delivery of Internet-based services through wireless technology is rapidly evolving, and Software.com may not be able to adequately address this market.

The market for wireless communications and the delivery of Internet-based services through wireless technology is rapidly evolving and is characterized by an increasing number of market entrants that have introduced or developed, or are in the process of introducing or developing, products that facilitate wireless communication and the delivery of Internet-based services through wireless devices. Software.com intends to devote significant efforts and resources on developing and marketing infrastructure applications for wireless communications and the wireless delivery of Internet-based content and services. Software.com's acquisitions of Telarc and AtMobile and Software.com's proposed merger with Phone.com were undertaken in part to address opportunities in that market. If wireless devices are not widely adopted for data communications or mobile delivery of Internet-based services, Software.com would not realize expected benefits from these acquisitions and proposed merger and its business would suffer.

In addition, the emerging nature of the market for wireless communications and Internet-based services via wireless devices may lead prospective customers to postpone adopting wireless devices or using wireless technology. As a result, the life cycle of Software.com's wireless products is difficult to estimate. Software.com may not be able to develop and introduce new products, services and enhancements that respond to technological changes or evolving industry standards on a timely basis, in which case Software.com's business would suffer. In addition, Software.com cannot predict the rate of adoption by wireless subscribers of these services or the price they will be willing to pay for these services. As a result, it is extremely difficult to predict the pricing of these services and the future size and growth rate of the wireless market.

Software.com's service provider customers face implementation and support challenges in expanding wireless communications and introducing Internet-based services via wireless devices, which may slow their rate of adoption or implementation of the services Software.com's wireless messaging products enable. Historically, service providers have been relatively slow to implement new complex services such as wireless messaging services and wireless delivery of Internet content. In addition, service providers may encounter greater customer service demands to support Internet-based services via wireless devices than they do for their traditional Internet services. Software.com has limited or no control over the pace at which service providers implement these new services. The failure of service providers to introduce and support services utilizing Software.com's products in a timely and effective manner could harm its business.

Software.com's intellectual property or proprietary rights could be misappropriated, which could force Software.com to become involved in expensive and time-consuming litigation.

Software.com's ability to compete and continue to provide technological innovation is substantially dependent upon internally developed technology, including the entire InterMail product line. Software.com relies on a combination of copyright, trade secret, and trademark law to protect its technology, although it believes that other factors such as the technological and creative skills of its personnel, new product developments, frequent product and feature enhancements, and reliable product support and maintenance are more essential to maintaining a technology leadership position. As a result of the AtMobile acquisition, Software.com acquired one patent and a number of patent applications, specifically for wireless subject matter.

Software.com generally enters into confidentiality and nondisclosure agreements with its employees, consultants, prospective customers, licensees, and corporate partners. In addition, Software.com control access to and distribution of its software, documentation, and other proprietary information. Except for certain limited escrow arrangements, Software.com does not provide third parties with access to the source code for Software.com's products. Despite Software.com's efforts to protect its intellectual property and proprietary rights, unauthorized parties may attempt to copy or otherwise obtain and use Software.com's products or technology. Effectively policing the unauthorized use of Software.com's products is time consuming and costly, and there can be no assurance that the steps taken by Software.com will prevent misappropriation of Software.com's technology, particularly in foreign countries where in many instances the local laws or legal systems do not offer the same level of protection as in the United States.

If others claim that Software.com's products infringe their intellectual property rights, Software.com may be forced to seek expensive licenses, reengineer its products, engage in expensive and time-consuming litigation, or stop marketing its products.

Software.com attempts to avoid infringing known proprietary rights of third parties in its product development efforts. However, Software.com does not regularly conduct comprehensive patent searches to determine whether the technology used in its products infringes patents held by third parties. There are many issued patents as well as patent applications in the electronic messaging field. Because patent applications in the United States are not publicly disclosed until the patent is issued, applications may have been filed which relate to Software.com's software products. In addition, Software.com's competitors and other companies as well as research and academic institutions have conducted research for many years in the electronic messaging field, and this research could lead to the filing of further patent applications. If Software.com were to discover that its products violated or potentially violated third party proprietary rights, it might not be able to obtain licenses to continue offering those products without substantial reengineering. Any reengineering effort may not be successful, nor can Software.com be certain that any licenses would be available on commercially reasonable terms.

Substantial litigation regarding intellectual property rights exists in the software industry, and Software.com expects that software products may be increasingly subject to third-party infringement claims as the number of competitors in its industry segments grows and the functionality of software products in different industry segments overlaps. Any third-party infringement claims could be time-consuming to defend, result in costly litigation, divert management's attention and resources, cause product and service delays or require Software.com to enter into royalty or licensing agreements. Any royalty or licensing arrangements, if required, may not be available on terms acceptable to Software.com, if at all. A successful claim of infringement against Software.com and its failure or inability to license the infringed or similar technology could have a material adverse effect on its business, financial condition, and results of operations.

The geographic disbursement of Software.com's senior management could impede their ability to communicate effectively.

Software.com's senior management and key personnel are based in several different offices, which makes coordination of projects more difficult. For example, John MacFarlane, Software.com's Chief Executive Officer,

34

and Amy Staas, Software.com's Chief Financial Officer, are based at Software.com's headquarters in Santa Barbara, California, while Valdur Koha, Software.com's President, and John Poulack, Software.com's Senior Vice President, Operations, are based at Software.com's office in Lexington, Massachusetts. In addition, acquisitions and Software.com's proposed merger with Phone.com may have the effect of increasing geographic disbursement of senior management and key personnel. The geographic disbursement of Software.com's senior management team and key personnel could impede their ability to communicate effectively or work together efficiently, either of which could harm Software.com's business, financial condition, and operating results.

The security provided by Software.com's messaging products could be breached, in which case Software.com's reputation, business, financial condition, and operating results could suffer.

The occurrence or perception of security breaches could harm Software.com's business, financial condition, and operating results. A fundamental requirement for online communications is the secure transmission of confidential information over the Internet. Third parties may attempt to breach the security provided by Software.com's messaging products, or the security of its customers' internal systems. If they are successful, they could obtain confidential information about Software.com's customers' end users, including their passwords, financial account information, credit card numbers, or other personal information. Software.com's customers or their end users may file suits against it for any breach in security. Even if Software.com is not held liable, a security breach could harm Software.com's reputation, and even the perception of security risks, whether or not valid, could inhibit market acceptance of Software.com's products. Despite Software.com's implementation of security measures, its software is vulnerable to computer viruses, electronic break-ins and similar disruptions, which could lead to interruptions, delays, or loss of data. Software.com may be required to expend significant capital and other resources to license encryption or other technologies to protect against security breaches or to alleviate problems caused by these breaches. In addition, Software.com's customers might decide to stop using Software.com's software if their end users experience security breaches.

Future governmental regulation of the Internet could limit Software.com's ability to conduct its business.

Although there are currently few laws and regulations directly applicable to the Internet and commercial messaging, a number of laws have been proposed involving the Internet, including laws addressing user privacy, pricing, content, copyrights, distribution, antitrust, and characteristics and quality of products and services. Further, the growth and development of the market for online messaging may prompt calls for more stringent consumer protection laws that may impose additional burdens on those companies, including Software.com, that conduct business online. The adoption of any additional laws or regulations may impair the growth of the Internet or commercial online services, which would decrease the demand for Software.com's services and could increase its cost of doing business or otherwise harm Software.com's business, financial condition, and operating results. Moreover, the applicability of existing laws governing property ownership, sales and other taxes, libel, and personal privacy to the Internet is uncertain and may take years to resolve.

Software.com's stock price may be volatile, exposing it to expensive and time- consuming securities class action litigation.

The stock market in general, and the stock prices of Internet-related companies in particular, have recently experienced extreme volatility, which has often been unrelated to the operating performance of any particular company or companies. If market or industry-based fluctuations continue, Software.com's stock price could decline below current levels regardless of its actual operating performance. Furthermore, the historical trading volume of Software.com's stock is not indicative of any future trading volume of Software.com's stock because a substantial portion of shares were not eligible for sale until recently. Therefore, if a large number of shares of Software.com's stock are sold in a short period of time, Software.com's stock price will decline. In the past, securities class action litigation has often been brought against companies following periods of volatility in their stock prices. Software.com may in the future be the target of similar litigation. Securities litigation could result in substantial costs and divert Software.com's management's time and resources, which could harm its business, financial condition, and operating results.

THE MERGER

This section of the joint proxy statement/prospectus describes the proposed merger. Although Phone.com and Software.com believe that the description in this section covers the material terms of the merger and the related transactions, this summary may not contain all of the information that is important to you. You should carefully read the entire joint proxy statement/prospectus for a more complete understanding of the merger.

General

The merger agreement provides that, at the effective time of the merger, Silver Merger Sub, a wholly-owned subsidiary of Phone.com, will merge with and into Software.com, with Software.com continuing in existence as the surviving corporation. Each share of Software.com common stock issued and outstanding at the effective time of the merger will be converted into 1.6105 shares of Phone.com common stock. Upon completion of the merger, Software.com will be a wholly-owned subsidiary of Phone.com and market trading of Software.com common stock will cease.

Background of the Merger

In light of the rapid changes in the wireless and wireline telecommunications and Internet industries, it had become a regular practice of the board of directors of both Phone.com and Software.com to review periodically with senior management the relative position of each company in these industries, changes in the competitive landscape and technology as well as strategic alternatives available to each company in order to remain competitive and enhance stockholder value. In connection with this ongoing review of long-term strategic plans, each company had been considering a wide range of strategic options, including internal growth strategies, growth through various strategic alliances, investments, acquisitions or business combinations. In furtherance of these objectives, from time to time each company has had contact with various parties to explore on a preliminary basis several of these alternatives, including some discussions with one or more parties during the time periods described below.

During the fourth quarter of calendar year 1999, Phone.com evaluated products from various developers of electronic mail software, including from Software.com, for the purpose of adding electronic mail applications to its product line.

On January 14, 2000, Jeff Damir, Vice President of Phone.com, and Obie Oberoi, Director of Business Development of Phone.com, met with Tom Cullen, Senior Vice President of World Wide Sales of Software.com, and other representatives of Software.com for the purpose of discussing a potential customer/supplier relationship between the two companies. At this meeting, the representatives of Phone.com stated that Phone.com was interested in incorporating Software.com's InterMail Mx product into Phone.com's product line. The representatives of both companies discussed Phone.com's use of the InterMail Mx product, but were unable to reach an agreement.

On January 21, 2000, Alain Rossmann, Chairman and Chief Executive Officer of Phone.com, met with John L. MacFarlane, Chief Executive Officer of Software.com, to discuss Software.com's electronic mail software and the possibility of including that software in Phone.com's products. Mr. Rossmann and Mr. MacFarlane discussed a potential customer/supplier relationship between the two companies but were unable to reach any agreement. Mr. Rossmann also explained at this meeting that Phone.com, as part of its growth strategies, periodically explores acquisitions, business combinations and other strategic transactions. Mr. Rossmann then discussed with Mr. MacFarlane whether Software.com would be interested in exploring the possibility of a strategic transaction with Phone.com, including a business combination. Mr. MacFarlane indicated that Software.com was presently focused on other types of growth strategies and that Software.com was not interested in exploring a possible strategic transaction with Phone.com.

In connection with Phone.com's acquisition of Onebox.com, Inc., or Onebox, Phone.com learned during its due diligence investigation of Onebox that Software.com was an important supplier of software to Onebox.

42

On April 4, 2000, Mr. Rossmann, Ross Bott, former Chief Executive Officer of Onebox and current Chief Operating Officer of Phone.com, and Mike Mulica Vice President of Worldwide Sales, Consulting and Support for Phone.com, met with Mr. McFarlane, Mr. Cullen and Adarbad Master, Chief Technology Officer of Software.com. At this meeting, the participants discussed Software.com's future customer/supplier relationship with Onebox following its pending acquisition by Phone.com, including a proposed amendment to the existing agreement. At this meeting, Mr. Rossmann again raised with Mr. MacFarlane the possibility of Phone.com and Software.com exploring a strategic transaction including a business combination. Mr. MacFarlane declined to pursue discussions concerning a potential business combination but instead indicated a desire to expand the existing customer/supplier relationship.

At its regularly scheduled board meeting on April 12, 2000, Mr. Rossmann briefed the board of directors of Phone.com on recent discussions with various entities, including Software.com.

On April 13, 2000, Software.com and Onebox entered into an amendment to their existing contract. On April 14, 2000, Phone.com completed its acquisition of Onebox.

During the remainder of April 2000 and May 2000, there were several telephone discussions among representatives of Phone.com and Software.com regarding expansion of their customer/supplier relationship, possible strategic relationships and transactions and the strategic objectives that could be achieved through such relationships and transactions.

On June 1, 2000, Mr. MacFarlane advised the Software.com board of directors that discussions had been held between Phone.com and Software.com regarding expanding the customer/supplier relationship with Phone.com, including the possibility of developing a strategic relationship with Phone.com.

On June 6, 2000, Mr. Rossmann called Mr. MacFarlane and suggested that they meet again to discuss the potential benefits of expanding the customer/supplier relationship between the two companies and the benefits of a strategic transaction including a possible business combination between Phone.com and Software.com. Mr. MacFarlane agreed to meet with Mr. Rossmann on June 13, 2000. During their June 13, 2000 meeting, Mr. Rossmann and Mr. MacFarlane discussed certain potential strategic transactions including a business combination of Phone.com and Software.com, although no agreement was reached on how to proceed.

On June 15, 2000, Mr. MacFarlane telephoned Mr. Rossmann and stated that Software.com would agree to explore with Phone.com in more detail the possibility of a business combination transaction. During this discussion, Mr. MacFarlane stated that, given the relatively comparable market capitalization of the two companies, any possible business combination transaction should be structured as a "merger of equals," after which the shareholders of Phone.com and Software.com would each, collectively, own approximately 50 percent of the resulting company. Mr. Rossmann and Mr. MacFarlane agreed to discuss such a potential business combination with their respective boards of directors and management.

On June 16, 2000, Mr. Rossmann and Kennen Hagen, Vice President of Corporate Development of Phone.com, met with representatives of Credit Suisse First Boston. Credit Suisse First Boston had previously acted as financial advisor to Phone.com in connection with its initial public offering and other transactions, including its acquisition of Onebox. At this meeting the representatives of Phone.com discussed certain potential strategic transactions with the representatives of Credit Suisse First Boston including a possible business combination transaction with Software.com.

On June 18, 2000, in a status update to the board of directors on several business items, Mr. MacFarlane briefed the Software.com board of directors on recent discussions with Phone.com regarding a potential strategic relationship.

On June 22, 2000, representatives of Phone.com and Credit Suisse First Boston again met to discuss strategic transactions including a possible business combination transaction between Phone.com and Software.com.

43

Also on June 22, 2000, Mr. Mulica met with Mr. Cullen to discuss the synergies and potential impact on product sales of a possible business combination transaction between Phone.com and Software.com. At this meeting, Mr. Mulica and Mr. Cullen agreed that the potential synergies from such a business combination could potentially have a strong positive impact on the product sales of both companies. Mr. Mulica so advised members of his senior management.

On June 26, 2000, Mr. MacFarlane met with other members of the Software.com's senior management for the purpose of informing them of the need to evaluate a potential business combination transaction with Phone.com. Mr. Cullen advised members of his management team of his June 22, 2000, meeting with Mr. Mulica. Also on June 26, 2000, Mr. Rossmann telephoned Mr. MacFarlane to discuss the potential business combination transaction between Phone.com and Software.com and agreed to meet with Mr. MacFarlane on June 28, 2000.

On June 28, 2000, Mr. Rossmann met with Mr. MacFarlane to discuss a potential "merger of equals" business combination transaction between Phone.com and Software.com, including possible transaction structures and proposed management of the combined company.

On July 5, 2000, Mr. Rossmann and Alan Black, Chief Financial Officer, Vice President of Finance and Administration and Treasurer of Phone.com, met with Mr. MacFarlane and other members of Software.com's senior management.

The Phone.com board has approved the merger agreement and has deemed the merger advisable and has determined that the terms of the merger agreement are fair and in the best interests of Phone.com and its stockholders.

. the potential revenue synergies including cross-selling opportunities for the products of both companies;

. the terms of the merger agreement, including the benefits to be received by Phone.com and the dilution to Phone.com's stockholders in the merger and a comparison of comparable merger transactions;

. Credit Suisse First Boston's opinion to the Phone.com board of directors that the exchange ratio in the merger is fair to Phone.com from a financial point of view; and

The Phone.com board of directors also identified and considered a number of potentially negative factors in its deliberations concerning the merger, including but not limited to:

. the challenges of integrating the management teams, strategies, cultures and organizations of the companies;

. the risk that despite the efforts of the combined company, key management and other personnel might not remain employed by the combined company;

. the risk that certain key employees of both Phone.com and Software.com that are parties to change of control agreements will leave the combined company upon any triggering of such change of control agreements, and the costs resulting from such departures;

. risks associated with fluctuations in Software.com's stock price and Phone.com's stock price prior to closing of the merger;

. the risk of disruption of sales momentum as a result of uncertainties created by the announcement of the merger;

. the possibility that the merger might not be consummated, even if approved by each company's stockholders including the possible effect of the termination fee and the Phone.com stock option agreement;

. the effect of the public announcement of the merger and the possibility that the merger might not be consummated on (a) demand for Phone.com's products and services, Phone.com's relationships with strategic partners, Phone.com's operating results and Phone.com's stock price and (b) Phone.com's ability to attract and retain key management and marketing, sales, technical and other personnel;

. the substantial charges to be incurred in connection with the merger, including costs of integrating the businesses and transaction expenses arising from the merger; and

. other applicable risks described in the section of this joint proxy statement/prospectus entitled "Risk Factors" on page .

The Phone.com board of directors believed that these risks were outweighed by the potential benefits of the merger.

The foregoing discussion is not exhaustive of all factors considered by the Phone.com board of directors. Each member of Phone.com's board may have considered different factors, and the Phone.com board of directors evaluated these factors as a whole and did not quantify or otherwise assign relative weights to factors considered. In addition, the Phone.com board of directors did not reach any specific conclusion with respect to each of the factors considered, or any aspect of any particular factor. Instead, the Phone.com board conducted an overall analysis of the factors described above.

Recommendation of the Phone.com Board of Directors. After due consideration, the Phone.com board of directors approved the merger by unanimous vote, deemed the merger advisable and determined that the merger is fair to and in the best interests of Phone.com and its stockholders.

Opinion of Phone.com's Financial Advisor

Credit Suisse First Boston has acted as Phone.com's financial advisor in connection with the merger. Phone.com selected Credit Suisse First Boston based on Credit Suisse First Boston's experience, expertise and reputation, and familiarity with Phone.com's business. Credit Suisse First Boston is an internationally recognized investment banking firm and is regularly engaged in the valuation of businesses and securities in connection with mergers and acquisitions, leveraged buyouts, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes.

In connection with Credit Suisse First Boston's engagement, Phone.com requested that Credit Suisse First Boston evaluate the fairness, from a financial point of view, to Phone.com of the exchange ratio provided for in the merger. On August 8, 2000, at a meeting of the Phone.com board of directors held to evaluate the merger, Credit Suisse First Boston rendered to the Phone.com board of directors an oral opinion, which opinion was confirmed by delivery of a written opinion dated August 8, 2000, to the effect that, as of that date and based on and subject to the matters described in its opinion, the exchange ratio provided for in the merger was fair, from a financial point of view, to Phone.com.

The full text of Credit Suisse First Boston's written opinion, dated August 8, 2000, to the Phone.com board of directors, which sets forth, among other things, the procedures followed, assumptions made, matters considered and limitations on the review undertaken, is attached as Annex J and is incorporated into this document by reference. Holders of Phone.com common stock are urged to, and should, read this opinion carefully and in its entirety. Credit Suisse First Boston's opinion is addressed to the Phone.com board of directors and relates only to the fairness of the exchange ratio from a financial point of view, does not address any other aspect of the proposed merger or any related transaction and does not constitute a recommendation to any stockholder as to any matter relating to the merger. The summary of Credit Suisse First Boston's opinion in this document is qualified in its entirety by reference to the full text of the opinion.

In arriving at its opinion, Credit Suisse First Boston reviewed the merger agreement and related documents, as well as publicly available business and financial information relating to Phone.com and Software.com. Credit Suisse First Boston also reviewed other information relating to Phone.com and Software.com, including publicly available financial forecasts, that were provided to or discussed with Credit Suisse First Boston by Phone.com and Software.com. Credit Suisse First Boston also met with the managements of Phone.com and Software.com to discuss the businesses and prospects of Phone.com and Software.com and potential synergies that might be achieved in the merger. Credit Suisse First Boston considered financial and stock market data of Phone.com and Software.com, and compared those data with similar data for publicly held companies in businesses similar to those of Phone.com and Software.com. Credit Suisse First Boston considered, to the extent publicly available, the financial terms of other business combinations and other transactions which have recently been effected. Credit Suisse First Boston also considered other information, financial studies, analyses and investigations and financial, economic and market criteria which it deemed relevant.

In connection with its review, Credit Suisse First Boston did not assume any responsibility for independent verification of any of the foregoing information and relied on such information being complete and accurate in all material respects. With respect to the financial forecasts for Phone.com and Software.com, Credit Suisse First Boston assumed, with the consent of the managements of Phone.com and Software.com, that the forecasts represented reasonable estimates and judgments as to the future financial performance of Phone.com and Software.com. In addition, Credit Suisse First Boston relied on, without independent verification, the assessment of the managements of Phone.com and Software.com as to the strategic benefits anticipated to result from the merger, the existing and future technology and products of Phone.com and Software.com and the risks associated with the future technology and products, Phone.com's and Software.com's ability to integrate the businesses of Phone.com and Software.com, and Phone.com's and Software.com's ability to retain key employees of Phone.com and Software.com. Credit Suisse First Boston also assumed, with the consent of the Phone.com board of directors, that the merger would be treated as a tax-free reorganization for federal income tax purposes. In

51

addition, Credit Suisse First Boston was not requested to make, and did not make, an independent evaluation or appraisal of the assets or liabilities, contingent or otherwise, of Phone.com and Software.com, nor was Credit Suisse First Boston furnished with any evaluations or appraisals.

Credit Suisse First Boston's opinion is necessarily based upon information available to it, and financial, economic, market and other conditions as they existed and could be evaluated, on the date of the Credit Suisse First Boston opinion. Credit Suisse First Boston did not express any opinion as to what the value of the Phone.com common stock actually would be when issued in the merger or the prices at which the Phone.com common stock would trade after the merger. Although Credit Suisse First Boston evaluated the exchange ratio in the merger from a financial point of view, Credit Suisse First Boston was not requested to, and did not, recommend the specific consideration payable in the merger, which consideration was determined between Phone.com and Software.com. No other limitations were imposed on Credit Suisse First Boston with respect to the investigations made or procedures followed in rendering its opinion.

In preparing its opinion to the Phone.com board of directors, Credit Suisse First Boston performed a variety of financial and comparative analyses, including those described below. The summary of Credit Suisse First Boston's analyses described below is not a complete description of the analyses underlying Credit Suisse First Boston's opinion. The preparation of a fairness opinion is a complex process involving various determinations as to the most appropriate and relevant methods of financial analyses and the application of those methods to the particular circumstances and, therefore, a fairness opinion is not readily susceptible to partial analysis or summary description. In arriving at its opinion, Credit Suisse First Boston made qualitative judgments as to the significance and relevance of each analysis and factor that it considered. Accordingly, Credit Suisse First Boston believes that its analyses must be considered as a whole and that selecting portions of its analyses and factors or focusing on information presented in tabular format, without considering all analyses and factors or the narrative description of the analyses, could create a misleading or incomplete view of the processes underlying its analyses and opinion.

In its analysis, Credit Suisse First Boston considered industry performance, regulatory, general business, economic, market and financial conditions and other matters, many of which are beyond the control of Phone.com and Software.com. No company, transaction or business used in Credit Suisse First Boston's analyses as a comparison is identical to Phone.com and Software.com or the proposed merger, and an evaluation of the results of those analyses is not entirely mathematical. Rather, the analyses involve complex considerations and judgments concerning financial and operating characteristics and other factors that could affect the acquisition, public trading or other values of the companies, business segments or transactions being analyzed. The estimates contained in Credit Suisse First Boston's analyses and the ranges of valuations resulting from any particular analysis are not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than those suggested by the analyses. In addition, analyses relating to the value of businesses or securities do not purport to be appraisals or to reflect the prices at which businesses or securities actually may be sold. Accordingly, Credit Suisse First Boston's analyses and estimates are inherently subject to substantial uncertainty.

Credit Suisse First Boston's opinion and financial analyses were only one of many factors considered by the Phone.com board of directors in its evaluation of the proposed merger and should not be viewed as determinative of the views of the Phone.com board of directors or management with respect to the merger or the exchange ratio.

The following is a summary of the material financial analyses performed by Credit Suisse First Boston in connection with the preparation of its opinion and reviewed with the Phone.com board of directors at a meeting of the Phone.com board of directors held on August 8, 2000. The financial analyses summarized below include information presented in tabular format. In order to fully understand Credit Suisse First Boston's financial analyses, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses. Considering the data in the tables below without

52

considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of Credit Suisse First Boston's financial analyses.

Precedent Merger-of-Equals Transactions Analysis. Credit Suisse First Boston reviewed 70 precedent merger-of-equals transactions across a wide range of industries in order to determine the median and mean premium paid to the stockholders of the effective target in each transaction one trading day and 30 trading days prior to announcement of each transaction. Credit Suisse First Boston identified the acquiror and target in each transaction by considering the party issuing shares in the transaction, relative ownership and control of the combined entity and location of the combined entity's headquarters. Credit Suisse First Boston compared the results of this review to the premium to be paid to Software.com's stockholders in the merger utilizing closing prices for Phone.com common stock on August 7, 2000 at the exchange ratio in the merger. The results of this analysis are as follows:

                                                     Premium to Stock Price

No transaction utilized as a comparison in the precedent transactions analysis or precedent merger-of-equals transactions analysis is identical to the merger. In evaluating the business combination, Credit Suisse First Boston made judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of Phone.com and Software.com, such as the impact of competition on the businesses of Phone.com and Software.com and the industry generally, industry growth and the absence of any adverse material change in the financial condition and prospects of Phone.com, Software.com or the industry or in the financial markets in general. Mathematical analysis, such as determining the average or median, is not in itself a meaningful method of using comparable transaction data.

Analysis of Pro Forma Impact of the Merger. Credit Suisse First Boston also conducted an analysis of the potential pro forma impact of the merger on the estimated quarterly revenues, gross profit, operating income and net income of Phone.com through December 31, 2001 based on estimates prepared by securities research analysts. Credit Suisse First Boston noted that, assuming no synergies, the transaction would be dilutive to Phone.com's revenue per share during estimated calendar year 2001. Credit Suisse First Boston also noted that

55

the combined company would have a higher gross profit margin than would Phone.com on a stand-alone basis and that, assuming no synergies, the combined company would achieve profitability sooner than would Phone.com on a stand- alone basis.

Other Factors. In the course of preparing its opinion, Credit Suisse First Boston also reviewed and considered other information and data, including the potential pro forma effect of the merger on near term and one-year forward prices for Phone.com common stock.

Miscellaneous. Phone.com has agreed to pay Credit Suisse First Boston for its financial advisory services customary fees based on the aggregate value of the business combination. Phone.com also has agreed to reimburse Credit Suisse First Boston for all out-of-pocket expenses, including fees and reasonable expenses of legal counsel, and to indemnify Credit Suisse First Boston and related parties against liabilities, including liabilities under the federal securities laws, arising out of its engagement. Credit Suisse First Boston and its affiliates have in the past provided financial services to Phone.com and Software.com, and may in the future provide financial services to Phone.com, unrelated to the proposed merger, for which services Credit Suisse First Boston and its affiliates have received and will receive compensation. In the ordinary course of business, Credit Suisse First Boston and its affiliates may actively trade the debt and equity securities of Phone.com and Software.com for their own accounts and for the accounts of customers and, accordingly, may at any time hold long or short positions in those securities.

Opinion of Software.com's Financial Advisor

Under an engagement letter dated July 28, 2000, Software.com retained Morgan Stanley to provide it with financial advisory services and a financial fairness opinion in connection with the merger. Software.com's board of directors selected Morgan Stanley to act as its financial advisor based on Morgan Stanley's qualifications, expertise and reputation and its knowledge of the business and affairs of Software.com. At the meeting of the Software.com board of directors on August 8, 2000, Morgan Stanley rendered its oral opinion, subsequently confirmed in writing, that as of August 8, 2000, based upon and subject to the various considerations set forth in the opinion, the exchange ratio pursuant to the merger agreement was fair from a financial point of view to holders of shares of Software.com common stock.

The full text of the written opinion of Morgan Stanley, dated as of August 8, 2000, is attached as Annex K to this document. The opinion sets forth, among other things, the assumptions made, procedures followed, matters considered and limitations on the scope of the review undertaken by Morgan Stanley in rendering its opinion. We urge you to read the entire opinion carefully. Morgan Stanley's opinion is directed to Software.com's board of directors and addresses only the fairness from a financial point of view of the exchange ratio pursuant to the merger agreement to holders of shares of Software.com common stock as of the date of the opinion. It does not address any other aspects of the merger and does not constitute a recommendation to any holder of Software.com common stock as to how to vote at the Software.com special meeting. The summary of the opinion of Morgan Stanley set forth in this document is qualified in its entirety by reference to the full text of the opinion.

Morgan Stanley assumed and relied upon, without independent verification, the accuracy and completeness of the information reviewed by it for the purposes of its opinion. With respect to the financial projections and information relating to the strategic, financial and operational benefits anticipated from the merger, Morgan Stanley has assumed that they were reasonably prepared on bases reflecting the best currently available estimates and judgements of the future financial performance of Software.com and Phone.com, respectively. In addition, Morgan Stanley has assumed that the merger will be consummated in accordance with the terms set forth in the merger Agreement and will be treated as a tax- free reorganization pursuant to Section 368(a) of the Internal Revenue Code of 1986. Morgan Stanley's opinion is necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to Morgan Stanley as of, the date of its opinion.

Morgan Stanley relied upon the assessment by the managements of Software.com and Phone.com of their ability to retain key employees of Software.com and Phone.com, respectively. Morgan Stanley also relied upon, without independent verification, the assessment by the managements of Software.com and Phone.com of: (1) the strategic, financial and other benefits expected to result from the merger; (2) the timing and risks associated with the integration of Software.com and Phone.com; and (3) the validity of, and risks associated with, Software.com's and Phone.com's existing and future technologies, services or business models. Morgan Stanley has not made any independent valuation or appraisal of the assets or liabilities or technology of Software.com and Phone.com, nor has Morgan Stanley been furnished with any such appraisals.

In arriving at its opinion, Morgan Stanley was not authorized to solicit, and did not solicit, interest from any party with respect to an acquisition, business combination or other extraordinary transaction involving Software.com.

The following is a brief summary of the material analyses performed by Morgan Stanley in connection with its oral opinion and the preparation of its written opinion letter dated August 8, 2000. Some of these summaries of financial analyses include information presented in tabular format. In order to fully understand the financial analyses used by Morgan Stanley, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses.

On August 8, 2000, Software.com and Phone.com entered into the merger agreement whereby each holder of Software.com common stock would receive 1.6105 shares of Phone.com common stock. As a result, Software.com's shareholders would own approximately 50% of the combined company on a pro forma basis.

Exchange Ratio Premium Analysis. Morgan Stanley reviewed the ratios of the closing prices of Software.com common stock divided by the corresponding closing prices of Phone.com common shares over

57

various periods ending August 8, 2000. The ratios are referred to as average exchange ratios. Morgan Stanley examined the premiums represented by the exchange ratio set forth in the merger agreement over the averages of these period average exchange ratios, and found them to be as follows:

                                                         Transaction Exchange

Last twelve months.......................     0.881              82.8

Morgan Stanley noted that the transaction exchange ratio was higher than the average exchange ratio of the closing prices for all periods. Morgan Stanley also noted that the exchange ratio ranged from a low of 0.527x to a high of 1.994x over the 180-day period ending August 8, 2000. Morgan Stanley noted that the transaction exchange ratio was at the high-end of this relative trading range.

Morgan Stanley observed that the Software.com and Phone.com revenue multiples were in the middle of their respective peer groups. Further, Software.com's and Phone.com's valuation multiples were closer to each other than they were to certain other companies in the respective comparable company groups.

Morgan Stanley also noted that both Software.com and Phone.com were on the high end of their respective peer group(s) in terms of projected growth rates. For example, Phone.com had the highest growth rate when compared to the other companies in the Wireless Software and Services Index; however, its valuation multiple was in the middle of this range when compared to these comparable companies.

No company utilized in the peer group(s) comparison analysis is identical to Software.com or Phone.com. In evaluating the peer groups, Morgan Stanley made judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of Software.com and Phone.com, such as the impact of competition on the businesses of Software.com and Phone.com and the industry generally, industry growth and the absence of any adverse material change in the financial condition and prospects of Software.com and Phone.com or the industry or in the financial markets in general. Mathematical analysis, such as determining the average or median, is not in itself a meaningful method of using peer group data.

Morgan Stanley reviewed and analyzed future public market trading price targets for Software.com and Phone.com common stock prepared and published by securities research analysts during the period between July 21, 2000 and July 27, 2000 for each of the companies. These targets reflect each analyst's estimate of the future public market trading price of Software.com and Phone.com

common stock at the end of the twelve month period beginning the date of each of the respective research reports. The range of the price targets are set forth below:

                                                            Price Target
                                                      -------------------------
                                                      Low  High Average  Median
                                                      ---- ---- -------  ------
Software.com common stock............................ $140 $180 $  165   $  175
Phone.com common stock...............................  125  200    151      139

Transaction exchange ratio premium to ratio..........               47%      27%

Morgan Stanley compared the transaction exchange ratio to the ratio implied by the respective average and median price targets published by such analysts for Phone.com and Software.com, respectively. Morgan Stanley noted that the transaction exchange ratio reflected a 47% and 27% premium to the ratio of such average and median price targets. Morgan Stanley also noted that the range of exchange ratios resulting from comparing these ranges of price targets of Software.com and Phone.com was from 0.700 to 1.440. The transaction exchange ratio of 1.6105x was above this range.

Morgan Stanley noted that the public market trading price targets published by the securities research analysts do not necessarily reflect current market trading prices for Software.com and Phone.com common stock and these estimates are subject to uncertainties, including the future financial performance of Software.com and Phone.com and future financial market conditions.

Relative Contribution Analysis. Morgan Stanley compared Software.com and Phone.com stockholders' respective percentage ownership of the combined company to Software.com's and Phone.com's respective percentage contribution (and the implied ownership based on such contribution) to the combined company using revenues and gross profit based on equity research analysts' estimates.

Morgan Stanley noted that the implied pro forma Software.com ownership of the combined company was approximately 50% based on the transaction exchange ratio of 1.6105x. Morgan Stanley also noted that the 50% ownership position was higher than Software.com's contribution to the combined company in future periods, based on the revenue and gross profit projections used.

Morgan Stanley also noted that Software.com was already profitable, as of the second quarter of 2000 on an operating income basis, excluding one-time charges while Phone.com had negative operating income, excluding one-time charges. As a result, the contribution analysis based on operating income was not meaningful.

Analysis of Stock Price Premiums Paid. Morgan Stanley also compared publicly available statistics for merger transactions involving mergers of equals of public companies for 27 transactions, between January 1997 to August 8, 2000, where the target company's ownership of the newly formed entity exceeded 35%. Morgan Stanley reviewed the premiums to the unaffected stock price of the target company 1-day and 30-days prior to announcement for each of these transactions.

Based on these analyses, Morgan Stanley applied a 0% to 25% premium to the current exchange ratio of Software.com common stock to Phone.com common stock and calculated a reference exchange ratio range of 1.380x to 1.725x. Morgan Stanley noted that the transaction exchange ratio was within this range.

No company or transaction utilized in the analysis of stock price premiums paid is identical to Software.com or Phone.com or the merger. In evaluating the precedent acquisition transactions, Morgan Stanley made judgments and assumptions with regard to general business, market and financial conditions and other matters, which are beyond the control of Software.com and Phone.com, such as the impact of competition on the business of Software.com, Phone.com, or the industry generally, industry growth and the absence of any adverse material change in financial condition of Software.com, Phone.com or the industry or in the financial markets in general, which could affect the public trading value of the companies and the aggregate value of the transactions to which they are being compared.

Accretion/Dilution Analysis: Morgan Stanley analyzed the impact on revenues per share based on the transaction exchange ratio for the Software.com shareholders. Morgan Stanley utilized equity research analyst estimates to determine the revenues in Calendar Year 2000 and Calendar Year 2001.

                                                   Accretion/Dilution to

Based on equity research analysts' revenue estimates for Calendar Year 2001 for both Software.com and Phone.com and assuming no synergies, Morgan Stanley calculated that this transaction would be 16% accretive to Software.com shareholders on a revenue per share basis. Assuming $75 million in synergies for Calendar Year 2001, the accretion would be approximately 34%.

In connection with the review of the merger by Software.com's board of directors, Morgan Stanley performed a variety of financial and comparative analyses for purposes of rendering its opinion. The preparation of a fairness opinion is a complex process and is not necessarily susceptible to a partial analysis or summary description. In arriving at its opinion, Morgan Stanley considered the results of all of its analyses as a whole and did not attribute any particular weight to any analysis or factor it considered. Morgan Stanley believes that selecting any portion of its analyses, without considering all analyses as a whole, would create an incomplete view of the process underlying its analyses and opinion. In addition, Morgan Stanley may have given various analyses and factors more or less weight than other analyses and factors, and may have deemed various assumptions more or less probable than other assumptions. As a result, the ranges of valuations resulting from any particular analysis described above should not be taken to be Morgan Stanley's view of the actual value of Software.com or Phone.com. In performing its analyses, Morgan Stanley made numerous assumptions with respect to industry performance, general business and economic conditions and other matters. Many of these assumptions are beyond the control of Software.com or Phone.com. Any estimates contained in Morgan Stanley's analyses are not necessarily indicative of future results or actual values, which may be significantly more or less favorable than those suggested by such estimates.

Morgan Stanley conducted the analyses described above solely as part of its analysis of the fairness of the exchange ratio pursuant to the merger agreement from a financial point of view to holders of shares of Software.com common stock and in connection with the delivery of its opinion to Software.com's board of directors. These analyses do not purport to be appraisals or to reflect the prices at which shares of common stock of Software.com or Phone.com might actually trade.

61

The exchange ratio pursuant to the merger agreement was determined through arm's-length negotiations between Software.com and Phone.com and was approved by Software.com's board of directors. Morgan Stanley provided advice to Software.com during these negotiations. Morgan Stanley did not however, recommend any specific exchange ratio to Software.com or that any specific exchange ratio constituted the only appropriate exchange ratio for the merger.

In addition, Morgan Stanley's opinion and its presentation to Software.com's board of directors was one of many factors taken into consideration by Software.com's board of directors in deciding to approve the merger. Consequently, the analyses as described above should not be viewed as determinative of the opinion of Software.com's board of directors with respect to the exchange ratio or of whether Software.com's board of directors would have been willing to agree to a different exchange ratio.

Software.com's board of directors retained Morgan Stanley based upon Morgan Stanley's qualifications, experience and expertise. Morgan Stanley is an internationally recognized investment banking and advisory firm. Morgan Stanley, as part of its investment banking and financial advisory business, is continuously engaged in the valuation of businesses and securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and valuations for corporate, estate and other purposes. In the ordinary course of Morgan Stanley's trading and brokerage activities, Morgan Stanley or its affiliates may at any time hold long or short positions, may trade or otherwise effect transactions, for its own account or for the account of customers in the equity and other securities of Software.com, Phone.com or any other parties involved in the merger.

Under the engagement letter, Morgan Stanley provided financial advisory services and a financial fairness opinion in connection with the merger, and Software.com agreed to pay Morgan Stanley a customary fee for providing financial advisory services and a financial fairness opinion in connection with the merger. Software.com has also agreed to reimburse Morgan Stanley for its expenses incurred in performing its services. In addition, Software.com has agreed to indemnify Morgan Stanley and its affiliates, their respective directors, officers, agents and employees and each person, if any, controlling Morgan Stanley or any of its affiliates against certain liabilities and expenses, including certain liabilities under the federal securities laws, related to or arising out of Morgan Stanley's engagement.

Certain United States Federal Income Tax Considerations

The following is a summary of certain federal income tax considerations of the merger to the holders of Software.com common stock that exchange such stock for Phone.com common stock pursuant to the merger. This summary addresses only such stockholders who hold their Software.com common stock as a capital asset and will hold Phone.com common stock received in exchange therefor as a capital asset. This summary does not address all United States federal income tax considerations that may be relevant to particular stockholders in light of their individual circumstances or to stockholders that are subject to special rules, such as financial institutions, tax-exempt organizations, insurance companies, dealers in securities, foreign stockholders, stockholders who hold Software.com common stock as part of a straddle, hedge, or conversion transaction, and stockholders who acquired their Software.com common stock pursuant to the exercise of employee stock options or otherwise as compensation. The following summary is based upon the provisions of the Internal Revenue Code of 1986, as amended, applicable Treasury regulations thereunder, judicial decisions and current administrative rulings, as of the date hereof, all of which are subject to change, possibly on a retroactive basis. Tax considerations under state, local, foreign, and other laws are not addressed herein. Accordingly, each stockholder is advised to consult his or her tax advisor as to the particular facts and circumstances which may be unique to such stockholder and also as to any estate, gift, state, local, foreign, or federal tax considerations arising out of the merger.

No rulings have been or will be requested from the Internal Revenue Service with respect to any of the matters discussed herein. There can be no assurance that future legislation, regulations, administrative rulings or court decisions would not alter the tax considerations set forth below. It is a condition to the obligation of Phone.com to consummate the merger that Phone.com receive an opinion from its counsel, Skadden, Arps, Slate,

62

Meagher & Flom LLP, and it is a condition to the obligation of Software.com to consummate the merger that Software.com receive an opinion from its counsel, Wilson Sonsini Goodrich & Rosati, Professional Corporation, in both cases substantially to the effect that, based upon certain facts, representations, and assumptions, the merger will constitute a "reorganization" within the meaning of section 368(a) of the Internal Revenue Code of 1986, as amended. The issuance of such opinions is conditioned, among other things, on the receipt by Skadden, Arps, Slate, Meagher & Flom LLP and Wilson Sonsini Goodrich & Rosati, Professional Corporation, of representation letters from each of Phone.com, Silver Merger Sub and Software.com, in each case, in form and substance reasonably satisfactory to Skadden, Arps, Slate, Meagher & Flom LLP and Wilson Sonsini Goodrich & Rosati, Professional Corporation. The following summary assumes that the merger will be consummated as described in the merger agreement and this joint proxy statement/prospectus and that the merger will constitute a "reorganization" within the meaning of section 368(a) of the Internal Revenue Code of 1986, as amended.

Treatment of Software.com, Phone.com and Silver Merger Sub. No gain or loss will be recognized by Software.com, Phone.com, or Silver Merger Sub as a result of the merger.

Exchange of Software.com Common Stock for Phone.com Common Stock. A holder of Software.com common stock whose shares of Software.com common stock are exchanged in the merger for Phone.com common stock will not recognize gain or loss, except to the extent of cash, if any, received in lieu of a fractional share. See "Cash in Lieu of Fractional Shares" below. The aggregate tax basis of Phone.com common stock received by such holder will be equal to the aggregate tax basis of the Software.com common stock exchanged therefor (excluding any portion of the holder's basis allocable to fractional shares), and the holding period of Phone.com common stock received will include the holding period of the Software.com common stock exchanged therefor.

Cash in Lieu of Fractional Shares. A holder of Software.com common stock who receives cash in lieu of a fractional share of Phone.com common stock will be treated as having received such fractional share pursuant to the merger and then as having exchanged such fractional share for cash in a redemption by Phone.com. The amount of any gain or loss will be equal to the difference between the ratable portion of the tax basis of the Software.com common stock exchanged in the merger that is allocable to such fractional share and the cash received in lieu thereof. Any such gain or loss will constitute long-term capital gain or loss if such Software.com common stock has been held by the holder for more than one year at the time of the consummation of the merger.

Backup Withholding. Holders of Software.com common stock who receive cash in lieu of fractional shares of Phone.com common stock may be subject to backup withholding at a rate of 31%. Backup withholding will not apply, however, to a stockholder who (a) furnishes a correct taxpayer identification number and certifies, under penalties of perjury, that he or she is not subject to backup withholding on a Form W-9, (b) provides a certificate of foreign status on Form W-8, or (c) is otherwise exempt from backup withholding. A stockholder who fails to provide the correct taxpayer identification number on Form W-9 may be subject to a $50 penalty imposed by the Internal Revenue Service.

Reporting Requirements. Each holder of Software.com common stock that receives Phone.com common stock in the merger will be required to retain records and file with such stockholder's United States federal income tax return a statement setting forth certain facts relating to the merger.

Anticipated Accounting Treatment

The merger is expected to be accounted for as a pooling of interests for accounting purposes but pooling-of-interests accounting treatment is not a condition to the closing of the merger. Under this accounting method, the historical financial information of Phone.com and Software.com will be restated to reflect the combined financial position and operations of both companies. The combined financial position and operations will be adjusted to conform the accounting practices of the companies. Each of Phone.com and Software.com will use commercially reasonable efforts to obtain a letter from their respective independent auditors stating that they concur with the conclusion of Phone.com's and Software.com's management that the merger will qualify for pooling-of-interests accounting treatment.

63

Some of the conditions to be met to qualify for pooling-of-interests accounting treatment cannot be fully assessed until the passage of specified periods of time after the effective time of the merger, as certain of the conditions for pooling-of-interests accounting treatment address transactions occurring within such specified periods of time. Certain events, including certain transactions with respect to shares of Phone.com and Software.com common stock by affiliates of Phone.com and Software.com could prevent the merger from qualifying as pooling-of-interests for accounting purposes. For information concerning certain restrictions to be imposed on the transferability of shares of our common stock by affiliates in order, among other things, to ensure the availability of pooling-of-interests accounting treatment, see "The Merger Agreement--Affiliates."

If events occur that cause the merger to be deemed no longer to qualify for pooling-of-interests accounting treatment, the purchase method of accounting would be applied. The purchase method of accounting could have a material adverse effect on the reported operating results of Phone.com as compared to pooling-of-interests accounting treatment. See "Risk Factors--Failure to qualify for pooling-of-interests accounting treatment may impact reported operating results."

Interests of Directors and Officers in the Merger

When considering the recommendation of Software.com's and Phone.com's boards of directors, you should be aware that both companies' directors and officers have interests in the merger that are different from, or are in addition to, your interests.

In accordance with the terms of the merger agreement, the combined company's board of directors will be comprised of six members. It is expected that Donald J. Listwin, John L. MacFarlane and Bernard Puckett from Software.com's board of directors will join Phone.com's board of directors and Alain Rossmann, Reed E. Hundt and Roger Evans from Phone.com's board of directors will continue as directors. After the merger, Donald J. Listwin will be President and Chief Executive Officer of the combined company, Alain Rossmann will be Executive Vice President and Chairman, John L. MacFarlane will be Executive Vice President and Alan J. Black will be Chief Financial Officer. Donald J. Listwin is expected to resign from Software.com's board of directors and join Phone.com as its President and Chief Executive Officer prior to the merger.

Software.com's executive officers John L. MacFarlane and Valdur Koha and 14 other officers and key employees of Software.com have entered into change of control agreements that provide that if an officer's employment is terminated as a result of an "involuntary termination" during a period beginning two months before, and ending six months after a change of control, then one-half of the unvested portion of any stock options held by the officer will accelerate and become exercisable, subject to certain limitations. The merger with Phone.com may constitute a change of control. For purposes of the agreement, "involuntary termination" includes a change in the nature or scope of the officer's duties that is inconsistent with the position held by the officer immediately before the change of control, a material reduction of benefits or perquisites, a reduction in base cash salary, a relocation that is more than 20 miles from the officer's present location, any purported termination of the officer by Software.com, or the failure by Software.com to obtain the assumption of the change of control agreement.

Phone.com also has entered into change of control agreements with Alan Black, Benjamin Linder, Charles Parrish, Alain Rossmann and Mike Mulica and five other officers and key employees. These agreements provide that if the officer's employment is terminated as a result of an "involuntary termination" other than for cause within 18 months following a change of control transaction, the vesting of any stock option or restricted stock held by the officer shall be automatically accelerated so that the option or restricted stock becomes completely vested and exercisable. The merger with Software.com may constitute a change control. For purposes of the change of control agreements, "involuntary termination" includes a significant reduction in the employee's duties, authority or responsibilities, a substantial reduction of facilities or perquisites, a reduction in base salary, a material reduction in employee benefits, a relocation that is more than 30 miles from the employee's then-present location, the failure of successors of Phone.com to assume the change of control agreement, the purported termination of the employee other than for disability or cause, or any act or circumstances that would constitute a constructive termination under California case law or statute.

64

In addition, the directors and officers of Software.com have continuing indemnification against liabilities. Phone.com has agreed to cause the surviving corporation in the merger to indemnify each Software.com officer and director to the same extent as provided in Software.com's certificate of incorporation and bylaws and the indemnification agreements between Software.com and its officers and directors. In addition, Phone.com has agreed to cause the surviving corporation to maintain Software.com's directors' and officers' liability insurance for at least six years from the completion of the merger.

Regulatory Clearances and Approvals

Hart-Scott-Rodino Antitrust Improvements Act

Phone.com and Software.com cannot complete the merger until they give notification and furnish information to the Federal Trade Commission and the Antitrust Division of the Department of Justice and observe a statutory waiting period requirement. Phone.com and Software.com filed the required notification and report forms with the Federal Trade Commission and the Antitrust Division and the waiting period was terminated on August 30, 2000. At any time before or after the effective time of the merger, and notwithstanding that the waiting period has terminated or the merger may have been consummated, the Federal Trade Commission, the Antitrust Division or any state could take any action under the applicable antitrust or competition laws as it deems necessary or desirable. This action could include seeking to enjoin the completion of the merger. Private parties may also institute legal actions under the antitrust laws under some circumstances.

No Dissenter's or Appraisal Rights

Under Delaware law, no holder of Phone.com common stock or Software.com common stock will have any dissenter's or appraisal rights in connection with the merger.

Quotation on the Nasdaq National Market

It is a condition to the merger that the shares of Phone.com common stock to be issued in the merger and the other shares to be reserved for issuance in connection with the merger be approved for trading on the Nasdaq National Market subject to official notice of issuance. The merger agreement provides that Phone.com will use its commercially reasonable efforts to cause the shares of Phone.com common stock to be issued in the merger and the shares of Phone.com common stock to be reserved for issuance in connection with the merger to be approved for trading on the Nasdaq National Market.

Delisting and Deregistration of Software.com Common Stock

If the merger is completed, Software.com common stock will be delisted from the Nasdaq National Market and will be deregistered under the Securities Exchange Act of 1934, as amended.

Federal Securities Laws Consequences

The shares of Phone.com common stock to be issued in the merger will be registered under the Securities Act of 1933, as amended. These shares will be freely transferable under the Securities Act, except for Phone.com common stock issued to any person who is deemed to be an affiliate of Software.com or the combined company. Persons who may be deemed to be affiliates include individuals or entities that control, are controlled by, or are under common control with Software.com and include Software.com's officers and directors, as well as its principal stockholders. Software.com's affiliates may not sell their Phone.com common stock acquired in the merger, except pursuant to:

. an effective registration statement under the Securities Act covering the resale of those shares;

. an exemption under paragraph (d) of Rule 145 under the Securities Act; or

. any other applicable exemption under the Securities Act.

THE MERGER AGREEMENT

This section is a summary of the material terms of the merger agreement, a copy of which is attached as Annex A to this document. The following description does not purport to be complete and is qualified in its entirety by reference to the merger agreement. You should refer to the full text of the merger agreement for details of the merger and the terms and conditions of the merger agreement.

The Merger

The merger agreement provides that when all closing conditions have been satisfied or waived, Silver Merger Sub will be merged into Software.com, with Software.com as the surviving corporation. As a result of the merger, Software.com will become a wholly-owned subsidiary of Phone.com. The merger will become effective on the date of filing of a certificate of merger with the Secretary of State of the State of Delaware or a later date as is specified in the certificate of merger and agreed upon by the parties. This is referred to as the effective time of the merger.

The Exchange Ratio and Treatment of Software.com Securities

At the effective time of the merger:

. each share of Software.com common stock issued and outstanding immediately prior to the effective time, other than shares of Software.com common stock held in the treasury of Software.com, or owned by Phone.com or any direct or indirect subsidiary of Software.com or Phone.com, will be converted into the right to receive 1.6105 shares of Phone.com common stock; and

. shares of Software.com common stock held in the treasury of Software.com, or owned by Phone.com or any direct or indirect subsidiary of Software.com or Phone.com, will be canceled and no Phone.com common stock or other consideration will be delivered in exchange for this cancellation.

Each outstanding option or warrant to purchase Software.com common stock will be converted at the effective time of the merger into, and will become an option or warrant to purchase, 1.6105 shares of Phone.com common stock for each share of Software.com common stock covered by the option or warrant before the merger. After conversion, the exercise price per share of Phone.com common stock subject to each option and warrant will equal its pre-conversion exercise price per share of Software.com common stock divided by 1.6105. Each such outstanding option or warrant to purchase Software.com common stock, whether or not exercisable, shall be assumed by Phone.com and shall be subject to, and exercisable upon, the same terms and conditions as under the applicable stock plan, except as provided in the merger agreement.

At the effective time of the merger, all outstanding rights to purchase Software.com common stock under the Software.com Employee Stock Purchase Plan will be converted, in accordance with the exchange ratio of 1.6105, into, and will become rights to purchase shares of Phone.com common stock. Each converted right and outstanding offering period in effect under the Software.com Employee Stock Purchase Plan immediately prior to the effective time shall be assumed by Phone.com.

Exchange of Certificates

As soon as reasonably practicable after the effective time of the merger, U.S. Stock Transfer Corporation, as exchange agent, will mail to each stockholder of record of Software.com a letter of transmittal containing instructions for the surrender of certificates representing Software.com common stock in exchange for certificates representing Phone.com common stock.

No fractional shares of Phone.com common stock will be issued in the merger. Instead of issuing fractional shares of Phone.com common stock to the holders of shares of Software.com common stock, Phone.com will pay cash in an amount equal to the fractional amount multiplied by the average of the closing price of a share of Phone.com common stock on the Nasdaq National Market for the ten most recent trading days Phone.com

66

common stock has traded ending on the trading day immediately prior to the effective time of the merger. No interest will be paid or accrued on cash in lieu of fractional shares, if any.

If, after six months from the effective time of the merger, a holder of shares of Software.com common stock has not surrendered the stock certificates representing such shares to the exchange agent, then the holder of stock certificates representing Software.com common stock may look only to Phone.com to receive its shares of Phone.com common stock, cash in lieu of fractional shares and any unpaid dividends and distributions on shares of Phone.com common stock. None of Phone.com, Silver Merger Sub, Software.com or the exchange agent will be liable to any holder of a certificate formerly representing shares of Software.com common stock for Phone.com common stock, cash in lieu of fractional shares, or any unpaid dividends and distributions properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws.

If, after seven years from the effective time of the merger, a holder of a certificate formerly representing shares of Software.com common stock has not surrendered the holder's certificate, then unclaimed shares of Phone.com common stock, cash in lieu of fractional shares and any unpaid dividends and distributions on shares of Phone.com common stock will, to the extent permitted by applicable law, become the property of Software.com as the surviving corporation of the merger.

Holders of Software.com common stock should not send in their certificates until they receive a letter of transmittal from the exchange agent.

Corporate Organization and Governance

Upon consummation of the merger, Software.com will become the surviving corporation and shall continue to be governed by the laws of the State of Delaware. The directors and officers of Silver Merger Sub at the effective time of the merger will be the directors and officers of the surviving corporation, until their respective successors are duly elected, appointed or qualified or until their earlier death, removal or resignation in accordance with the certificate of incorporation and by-laws of the surviving corporation.

The merger agreement contains reciprocal covenants made by each of us to the other relating to certain matters. Each of us has agreed that, except as provided in the merger agreement or with the consent of the other party, which shall not be unreasonably withheld or delayed prior to the time the merger becomes effective, it will conduct its business in the ordinary course consistent with past practice and will use its reasonable efforts to preserve its business organization and to maintain its existing relationships with customers, suppliers, employees, creditors and business partners.

Accordingly, each of us has agreed that neither it nor its subsidiaries will, prior to the effective time of the merger, without the consent of the other party, which consent shall not be unreasonably withheld or delayed:

. declare, set aside or pay any dividend or other distribution on any of its capital stock;

. split, combine or reclassify its common stock;

. purchase, redeem or otherwise acquire any of its capital stock or any of its subsidiaries' capital stock;

. issue additional shares of or securities convertible into, or options, warrants or rights to acquire, any capital stock, except issuances pursuant to the exercise of its options outstanding on the date of the merger agreement in accordance with their present terms;

. amend its certificate of incorporation or by-laws or similar organizational documents;

. acquire a substantial portion of the assets or securities of any business or person;

. make any material investment in any other individual or entity other than its subsidiaries;

. sell, lease, license, mortgage or encumber any assets other than in the ordinary course of business;

. take any action that would cause any of its representations and warranties to become inaccurate;

. incur or assume any debt or guarantee the debt of others other than in the ordinary course of business;

68

. settle any material claims or proceedings involving money damages except in the ordinary course of business;

. make any material tax election except in the ordinary course of business;

. enter into, modify, amend or terminate any material agreements other than in the ordinary course of business;

. increase the compensation of or benefits to officers or directors or materially increase the compensation of or benefits to employees except for increases in accordance with normal past practice, or provide any new or change any existing benefit plan, or enter into any employment agreement involving compensation in excess of $200,000 per year;

. change the accounting methods used by it or any of its subsidiaries or take any action to jeopardize the treatment of the merger as a pooling of interests for accounting purposes; or

. authorize, or commit or agree to take, any of the above actions.

In addition, Phone.com, Software.com and Silver Merger Sub have agreed not to take any action or permit any of their respective subsidiaries to take any action that could result in any of the closing conditions to the merger not being satisfied. Each of Phone.com, Software.com and Silver Merger Sub agree to advise the other parties if they are aware of any event that would cause a failure of any such closing condition.

No Solicitation of Transactions

In the merger agreement, each party has agreed that it will not, nor will it permit any of its subsidiaries to, nor will it authorize or permit any representatives retained by it or any of its subsidiaries to, directly or indirectly:

. solicit, initiate or encourage, or take any other action designed to facilitate, any inquiries or the making of any proposal the consummation of which would result in:

-- a transaction or series of transactions pursuant to which a person or group of persons, other than Phone.com and its subsidiaries or Software.com and its subsidiaries, would acquire beneficial ownership of more than 20% of the outstanding shares of its common stock;

-- any acquisition or proposed acquisition of it or any of its significant subsidiaries by a merger or other business combination, regardless of whether it or any of its subsidiaries survives the merger; or

-- any other transaction pursuant to which a third party would acquire, directly or indirectly, control of assets of it or any of its subsidiaries, including the equity securities of such subsidiaries, for consideration equal to 20% or more of the fair market value of all of the outstanding shares of its common stock.

. participate in any discussions or negotiations regarding any proposals or offers described above, each of which we will refer to as an "alternative transaction."

However, if either Phone.com or Software.com receives an unsolicited proposal with respect to an alternative transaction and the holders of its common stock have not adopted the merger proposals set forth in this joint proxy statement/prospectus, and if its board of directors determines in good faith, after consultation with outside legal counsel, that the failure to provide information or participate in such negotiations would result in a reasonable possibility that its board of directors would breach its fiduciary duties to its stockholders, then it may:

. furnish information with respect to itself and its subsidiaries pursuant to a customary confidentiality agreement containing terms no less restrictive than the one between Software.com and Phone.com; and

. participate in negotiations regarding such proposal.

Each party has also agreed in the merger agreement that its board of directors may not:

. withdraw, qualify or modify, or propose publicly to do any of the foregoing, in a manner adverse to the other party, its approval or recommendation with respect to the merger;

69

. approve or recommend, or propose publicly to approve or recommend, any alternative transaction; or

. cause its company to enter into an agreement with respect to any alternative transaction.

However, if Phone.com or Software.com receives a superior proposal and the holders of its common stock have not adopted the merger agreement, and if its board of directors determines in good faith, after consultation with outside legal counsel, that the failure to do so would result in a reasonable possibility that the board of directors would breach its fiduciary duties to its stockholders, then the board of directors may inform its stockholders that it no longer believes that the merger or this agreement is advisable and no longer recommends the merger proposal. However, prior to making such a determination, Phone.com or Software.com must provide the other notice which includes the terms and conditions of the superior proposal.

A "superior proposal" means any proposal made by a third party to enter into an alternative transaction that the board of directors of Phone.com or Software.com determines in its good faith judgment, after consultation with a financial advisor of nationally recognized reputation, to be more favorable to its stockholders than the merger. However, each party must submit the merger agreement to its stockholders even if its board of directors determines that is no longer advisable and no longer recommends the merger proposals.

Additionally, each party will promptly advise the other party of any request for information or of any proposal in connection with an alternative transaction, the material terms and conditions of such request or proposal and the identity of the person making such request or proposal and keep the other party reasonably informed of the status and details of any request or proposal.

The merger agreement provides that these restrictions will not prohibit Phone.com or Software.com from:

. complying with Rule 14e-2(a) and Rule 14d-9 under the Securities and Exchange Act of 1934, as amended; or

. making any disclosure to its stockholders if, in the good faith judgment of its board of directors, after consultation with outside counsel, the failure to disclose would be inconsistent with its board of directors' fiduciary duties to its stockholders.

Board of Directors' Agreement to Recommend

Subject to the provisions described above under "--No Solicitation of Transactions," Phone.com has agreed that its board of directors will recommend to its stockholders the approval of the issuance of shares of Phone.com common stock pursuant to the merger agreement and the amendment to its certificate of incorporation to change the name of Phone.com to .

Subject to the provisions described above under "--No Solicitation of Transactions," Software.com has agreed that its board of directors will recommend to its stockholders the approval and adoption of the merger agreement, the merger and the other transactions contemplated thereby.

Pooling Letters

Software.com will use commercially reasonable efforts to obtain from its independent auditor a letter stating that it concurs with the conclusion of Software.com's management that Software.com qualifies as a "combining company" for purposes of pooling-of-interests accounting. Phone.com will use commercially reasonable efforts to obtain from its independent accountant a letter stating that it concurs with the conclusion of Phone.com's management that the merger qualifies for pooling-of-interests accounting. In addition, both Phone.com and Software.com agree, on behalf of themselves and their subsidiaries, to use their reasonable efforts to cause the merger to be accounted for as a pooling of interests, although pooling-of-interests accounting treatment is not a condition to the merger.

70

Access to Information

Subject to existing confidentiality obligations, Software.com and Phone.com have agreed to afford each other and each of their respective representatives reasonable access during normal business hours to their respective properties, books, contracts, commitments, personnel and records.

Commercially Reasonable Efforts

Under the merger agreement and subject to the conditions and limitations specified in the merger agreement, the parties have agreed to cooperate with each other to take specified actions and to use commercially reasonable efforts to consummate the merger.

Indemnification, Exculpation and Insurance

The merger agreement provides that Phone.com agrees to indemnify, at all times after the effective time, directors or officers of Software.com, any of its subsidiaries or affiliates, to the same extent as provided in Software.com's certificate of incorporation or by-laws or indemnity agreements in effect at the effective time.

In addition, Phone.com also agrees to maintain for at least six years after the effective time of the merger directors' and officers' liability insurance policies on the same terms and conditions as Software.com's insurance policies in effect on August 8, 2000, which will cover events occurring prior to the effective time of the merger.

Affiliates

Phone.com's and Software.com's respective affiliates, for purposes of applicable Securities and Exchange Commission accounting releases with respect to pooling-of-interests accounting treatment, have delivered written agreements to the effect that such affiliates will not sell, transfer or otherwise dispose of or reduce their risk with respect to any shares of the common stock of our companies at any time from the date thirty days prior to the effective time until there has been a public filing or announcement that includes appropriate combined results of operations of Phone.com and Software.com.

Employee Benefits

After the closing of the merger, for a period of one year, Phone.com has agreed to provide all active employees of Software.com and their dependents and all qualified beneficiaries with coverage under one or more Phone.com welfare benefits plans, including health coverage, which, in the aggregate, is comparable to that provided under the Software.com benefit plans before the effective time of the merger.

Post-Merger Operations; Phone.com Board of Directors and Officers

After the merger, the headquarters of Phone.com and its subsidiaries will be located in Redwood City, California. The Phone.com board of directors has agreed to recommend that Phone.com's stockholders approve an amendment to Phone.com's certificate of incorporation to change the name of Phone.com to a name to be mutually agreed upon by Phone.com and Software.com. Phone.com has agreed that its board of directors will take all action necessary so that as of the effective time, the board of directors of Phone.com will consist of six members, three of whom were members of the Phone.com board of directors as of the date of the merger agreement designated by Phone.com and three of whom were members of the Software.com board of directors as of the date of the merger agreement designated by Software.com.

RELATED AGREEMENTS

Phone.com Stock Option Agreement

General

Phone.com and Software.com have entered into a stock option agreement giving Software.com the right to acquire shares of Phone.com. The stock option agreement may prevent a third party from completing a pooling-of-interests transaction with Phone.com and would make alternative transactions, including a merger with another company, significantly more expensive for a potential purchaser than would otherwise be the case. Accordingly, the stock option agreement may discourage third parties from proposing alternative transactions that may be more advantageous than the merger for Phone.com stockholders.

The stock option agreement gives Software.com an option to purchase shares of Phone.com common stock at an exercise price of $78.0625 per share. The maximum number of shares that Software.com may purchase under the option is 16,516,495 shares of Phone.com common stock, which represents 19.9% of the shares of Phone.com common stock outstanding on July 31, 2000.

Phone.com has attached the stock option agreement to this document as Annex B. Phone.com urges you to read the full text of the stock option agreement.

When the option may be exercised

The option will become exercisable when the merger agreement is terminated in a circumstance under which Software.com is permitted to receive a termination fee from Phone.com. These circumstances are described under "The Merger Agreement--Termination Fee and Expenses."

Events terminating the right to exercise

The right to exercise the option terminates if Software.com completes the merger. The right to exercise the option also terminates in the following circumstances:

. six months after the option first becomes exercisable, provided that, if the option cannot be exercised as of such date by reason of any applicable judgment, decree, law, regulation or order, or by reason of the waiting period under the HSR Act, then the right to exercise the option will terminate thirty days after such impediment has been removed or such waiting period has expired;

. twelve months after the termination of the merger agreement if such termination results from Phone.com's failure to obtain the required approval of merger agreement from the Phone.com stockholders, provided that Software.com is entitled to recover its expenses as described under the "The Merger Agreement--Termination Fee and Expenses," unless within such twelve-month period Phone.com is required to pay a termination fee to Software.com, as described under the "The Merger Agreement-- Termination Fee and Expenses," in which case the right to exercise the option shall terminate six months after the actual payment of the termination fee; and

. upon termination of the merger agreement under any other circumstances not described in item 2 above, which do not result in the option becoming exercisable.

Repurchase

At any time after the option becomes exercisable and before the option expires, Software.com may request that Phone.com repurchase all or any portion of the option, to the extent not previously exercised, and all or any portion of the shares of Phone.com common stock issued pursuant to the option as Software.com may designate.

The option will be repurchased at a price equal to the difference between
(i) the higher of (A) the highest price per share offered as of the date of such repurchase pursuant to any alternative transaction described under

76

the "The Merger Agreement--Termination Fee and Expenses" above, and (B) the average closing sale price of Phone.com common stock during the five trading days ending on the trading day immediately preceding the repurchase and (ii) option exercise price, multiplied by the number of shares of Phone.com common stock purchasable pursuant to the option. The shares of Phone.com common stock issued pursuant to the option will be repurchased at (i) the higher of (A) the highest price per share offered as of the date of such repurchase pursuant to any alternative transaction described under the "The Merger Agreement-- Termination Fee and Expenses," and (B) the average closing sale price of Phone.com common stock during the five trading days ending on the trading day immediately preceding such repurchase (ii) multiplied by the number of shares being repurchased.

Limitation on total profit

The "total profit" that Software.com can realize from the stock option agreement and the termination fee may not exceed $230,454,545. The "total profit" realized by Software.com is defined as the sum of the following amounts received by Software.com from:

. the sale of shares purchased under the option, less the purchase price for those shares;

. the sale of shares received as part of the termination fee;

. the repurchase of the option by Phone.com;

. the transfer of the option; and

. any expenses or termination fee received under the merger agreement.

Registration rights

Software.com may demand on two occasions that Phone.com file a registration statement, including a shelf registration statement, to register the shares of Phone.com common stock that it may acquire upon the exercise of the option. The registration rights terminate three years after the first exercise of the option. The option agreement also grants Software.com the right to have shares of Phone.com common stock that it may acquire upon exercise of the option included in registration statements filed by Phone.com for a period of two years after the first exercise of the option.

Adjustments

The type and number of securities purchasable under the option agreement will be adjusted appropriately to reflect any change in Software.com's common stock involving reclassifications, recapitalizations, stock dividends, dividends, split-ups, combinations, subdivisions, exchanges or similar events.

Transfer

Software.com may not transfer the exercise of rights or the option to any person without Phone.com's prior written consent.

Phone.com Voting Agreements

Certain stockholders of Phone.com have agreed with Software.com, and have granted John L. MacFarlane and Craig A. Shelburne of Software.com irrevocable proxies to vote all of the voting securities of Phone.com which are beneficially owned by them in favor of the issuance of Phone.com common stock in the merger and the amendment to Phone.com's certificate of incorporation to change the name of Phone.com. These stockholders have also agreed that beginning thirty days prior to the effective time of the merger, they will not sell or transfer the securities of Phone.com which are beneficially owned by them except to a person who executes the Phone.com voting agreement and have agreed in writing to be bound by its terms. As of July 31, 2000, these stockholders beneficially owned 10,752,845 shares of Phone.com common stock, representing approximately 13.0% of the voting power of the outstanding Phone.com common stock.

77

The voting agreement also restricts the stockholders and their representatives from initiating, taking, soliciting or encouraging any action to facilitate the making of any offer or proposal for any of (i) a transaction or series of transactions pursuant to which any person or group of persons other than Software.com and its subsidiaries acquires or would acquire, directly or indirectly, beneficial ownership of more than 20% of the outstanding shares of Phone.com, (ii) any acquisition or proposed acquisition of Phone.com or any of its significant subsidiaries, by a merger or other business combination or (iii) any other transaction pursuant to which any person or group of persons other than Software.com and its subsidiaries acquires or would acquire, directly or indirectly, control of assets of Phone.com or any of its subsidiaries for consideration equal to 20% or more of the fair market value of all of the outstanding shares of Phone.com common stock. The stockholders and their representatives are also prohibited from engaging in negotiations or discussions with or providing information to anyone who proposes such an alternative transaction to the extent Phone.com is prohibited from taking those actions.

The voting agreement will terminate on the earliest of:

. the completion of the merger;

. the termination of the merger agreement; and

. the mutual agreement of the parties to terminate the voting agreement.

The Phone.com voting agreement is attached as Annex D to this document. You should read it in its entirety.

Phone.com Affiliate Agreements

Each member of the Phone.com board of directors, each executive officer of Phone.com and certain significant stockholders of Phone.com have executed affiliate agreements. Under the affiliate agreements, these Phone.com officers, directors and stockholders agreed not to transfer or otherwise reduce their risk relative to any shares of Phone.com or Software.com common stock during the period from the date 30 days prior to the effective date of the merger until the combined company publicly announces financial results covering at least 30 days of combined operations of Phone.com and Software.com. The form of Phone.com affiliate agreement is attached as Annex F to this document, and you are urged to read it in its entirety.

Phone.com Rights Agreement

Phone.com has entered into a rights agreement that entitles each holder of Phone.com common stock to purchase one one-thousandth of a share of Series A Junior Participating Preferred Stock at a price of $500 per one one-thousandth of a share, subject to adjustment. Ten business days after a person or group of affiliated or associated persons acquires beneficial ownership of 15% or more of the outstanding shares of Phone.com common stock, other than as a result of repurchases of stock by Phone.com or certain inadvertent actions by institutional or certain other stockholders, and except pursuant to an offer for all outstanding shares of Phone.com common stock which the independent directors of Phone.com determine to be fair and in the best interests of Phone.com and its stockholders, and other than pursuant to the merger agreement, the Software.com option agreement and the Phone.com voting agreements, each holder of a right to purchase one one-thousandth of a share of Series A Junior Participating Preferred Stock will thereafter have the right to receive, upon exercise of the right, shares of Phone.com common stock having a value equal to two times the exercise price of the right.

At any time until the tenth business day after a person or group of affiliated or associated persons acquires beneficial ownership of 15% or more of the outstanding shares of Phone.com common stock, Phone.com may redeem the rights in whole, but not in part, at a price of $0.001 per right. This rights agreement will terminate on August 18, 2008, unless such date is extended or the rights are redeemed by Phone.com prior to such date.

78

This rights agreement may have certain anti-takeover effects. The rights will cause substantial dilution to a person or group that attempts to acquire Phone.com in a manner which causes the rights to become discount rights unless the offer is conditional upon a substantial number of rights being acquired.

Memorandum of Understanding Between Phone.com and Software.com

Phone.com and Software.com have entered into a memorandum of understanding which memorializes the intent of both Phone.com and Software.com to use good faith efforts to enter into definitive agreements regarding the rights of Phone.com to license, distribute, resell, sublicense, use and test all of the products commercially available to Software.com and the rights of Software.com to license, distribute, resell, sublicense, use and test all of the products commercially available to Phone.com. Each party has agreed to bear its own costs of such definitive documentation and has agreed to keep all information shared between the companies confidential pursuant to a confidentiality agreement. The memorandum of understanding between Phone.com and Software.com is attached as Annex I to this document. You should read it in its entirety.

On August 18, 2000, Software.com and Phone.com entered into a Reseller License and Services Agreement, or the VAR Agreement, as contemplated by the memorandum of understanding. The VAR Agreement provides that each party has the right to resell the other's products and services based on standard reseller discounts. There are no minimum commitments for either party under the VAR Agreement. In addition, the VAR Agreement contemplates that each party will provide sales and marketing training to resell the various products, and the parties will hold periodic meetings amongst various personnel to conduct such training. Other meetings will be held among various development personnel to evaluate integration opportunities for the products to be resold under the VAR Agreement. Each party will, for at least the first six months of the VAR Agreement, provide technical support to the customers of the other party who have sub-licensed the products.

Software.com Stock Option Agreement

General

Software.com and Phone.com have entered into a stock option agreement giving Phone.com the right to acquire shares of Software.com. The stock option agreement may prevent a third party from completing a pooling-of-interests transaction with Software.com and would make alternative transactions, including a merger with another company, significantly more expensive for a potential purchaser than would otherwise be the case. Accordingly, the stock option agreement may discourage third parties from proposing alternative transactions that may be more advantageous than the merger for Software.com stockholders.

The stock option agreement gives Phone.com an option to purchase shares of Software.com common stock at an exercise price of $125.7197 per share. The maximum number of shares that Phone.com may purchase under the option is 9,724,460 shares of Software.com common stock, which represents 19.9% of the shares of Software.com common stock outstanding on July 31, 2000.

Software.com has attached the stock option agreement to this document as Annex C. Software.com urges you to read the full text of the stock option agreement.

When the option may be exercised

The option will become exercisable when the merger agreement is terminated in a circumstance under which Phone.com is permitted to receive a termination fee from Software.com. These circumstances are described under "The Merger Agreement--Termination Fee and Expenses."

79

Events terminating the right to exercise

The right to exercise the option terminates if Phone.com completes the merger. The right to exercise the option also terminates in the following circumstances:

. six months after the option first becomes exercisable, provided that, if the option cannot be exercised as of such date by reason of any applicable judgment, decree, law, regulation or order, or by reason of the waiting period under the HSR Act, then the right to exercise the option will terminate thirty days after such impediment has been removed or such waiting period has expired;

. twelve months after the termination of the merger agreement if such termination results from Software.com's failure to obtain the required approval of merger agreement from the Software.com stockholders, provided that Phone.com is entitled to recover its expenses as described under the "The Merger Agreement--Termination Fee and Expenses," unless within such twelve-month period Software.com required to pay a termination fee to Phone.com as described under the "The Merger Agreement--Termination Fee and Expenses," in which case the right to exercise the option shall terminate six months after the actual payment of the termination fee; and

. upon termination of the merger agreement under any other circumstances not described in item 2 above, which do not result in the option becoming exercisable.

Repurchase

At any time after the option becomes exercisable and before the option expires, Phone.com may request that Software.com repurchase all or any portion of the option, to the extent not previously exercised, and all or any portion of the shares of Software.com common stock issued pursuant to the option as Phone.com may designate.

The option will be repurchased at a price equal to the difference between
(i) the higher of (A) the highest price per share offered as of the date of such repurchase pursuant to any alternative transaction described under the "The Merger Agreement--Termination Fee and Expenses" above, and (B) the average closing sale price of Software.com common stock during the five trading days ending on the trading day immediately preceding the repurchase and (ii) option exercise price multiplied by the number of shares of Software.com common stock purchasable pursuant to the option. The shares of Software.com common stock issued pursuant to the option will be repurchased at
(i) the higher of (A) the highest price per share offered as of the date of such repurchase pursuant to any alternative transaction described under the "The Merger Agreement--Termination Fee and Expenses," and (B) the average closing sale price of Software.com common stock during the five trading days ending on the trading day immediately preceding such repurchase (ii) multiplied by the number of shares being repurchased.

Limitation on total profit

The "total profit" that Phone.com can realize from the stock option agreement and the termination fee may not exceed $230,454,545. The "total profit" realized by Phone.com is defined as the sum of the following amounts received by Phone.com from:

. the sale of shares purchased under the option, less the purchase price for those shares;

. the sale of shares received as part of the termination fee;

. the repurchase of the option by Software.com;

. the transfer of the option; and

. any expenses or termination fee received under the merger agreement.

Registration rights

Phone.com may demand on two occasions that Software.com file a registration statement, including a shelf registration statement, to register the shares of Software.com common stock that it may acquire upon the exercise

80

of the option. The registration rights terminate three years after the first exercise of the option. The option agreement also grants Phone.com the right to have shares of Software.com common stock that it may acquire upon exercise of the option included in registration statements filed by Software.com for a period of two years after the first exercise of the option.

Adjustments

The type and number of securities purchasable under the option agreement will be adjusted appropriately to reflect any change in Software.com common stock occurs involving reclassifications, recapitalizations, stock dividends, dividends, split-ups, combinations, subdivisions, exchanges or similar events.

Transfer

Phone.com may not transfer the exercise of rights or the option to any person without Software.com's prior written consent.

Software.com Voting Agreements

Certain stockholders of Software.com have agreed with Phone.com, and have granted Alan Black and Steve Peters of Phone.com irrevocable proxies to vote all of the voting securities of Software.com which are beneficially owned by them in favor of the merger and any action required in furtherance of these matters and the merger. These stockholders have also agreed that beginning thirty days prior to the effective time of the merger, they will not sell or transfer the securities of Software.com which are beneficially owned by them except to a person who executes the Software.com voting agreement and have agreed in writing to be bound by its terms. As of July 31, 2000, these stockholders beneficially owned 9,331,547 shares of Software.com common stock, representing approximately 19.1% of the voting power of the outstanding Software.com common stock.

The voting agreement also restricts the stockholders and their representatives from initiating, taking, soliciting or encouraging any action to facilitate the making of any offer or proposal for any of (i) a transaction or series of transactions pursuant to which any person or group of persons other than Phone.com and its subsidiaries acquires or would acquire, directly or indirectly, beneficial ownership of more than 20% of the outstanding shares of Software.com, (ii) any acquisition or proposed acquisition of Software.com or any of its significant subsidiaries, by a merger or other business combination or (iii) any other transaction pursuant to which any person or group of persons other than Phone.com and its subsidiaries acquires or would acquire, directly or indirectly, control of assets of Phone.com or any of its subsidiaries for consideration equal to 20% or more of the fair market value of all of the outstanding shares of Software.com common stock. The stockholders and their representatives are also prohibited from engaging in negotiations or discussions with or providing information to anyone who proposes such an alternative transaction to the extent Software.com is prohibited from taking those actions.

The voting agreement will terminate on the earliest of:

. the completion of the merger;

. the termination of the merger agreement; and

. the mutual agreement of the parties to terminate the voting agreement.

81

effective date of the merger until the combined company publicly announces financial results covering at least 30 days of combined operations of Software.com and Phone.com.

Software.com Rights Agreement

Software.com has entered into a rights agreement which entitles each holder of Software.com common stock to purchase one one-thousandth of a share of Series A Participating Preferred Stock at a price of $600 per one one- thousandth of a share, subject to a adjustment. Ten business days after a person or group of affiliated or associated persons acquires, or announces a tender offer to acquire, beneficial ownership of 15% or more of the outstanding shares of Software.com common stock, other than pursuant to the merger agreement, the Phone.com option agreement and the Software.com voting agreements, each holder of a right to purchase one one-thousandth of a share of Series A Participating Preferred Stock will thereafter have the right to receive, upon exercise of the right, shares of Software.com stock having a value equal to two times the exercise price of the right.

At any time until the fifth business day after a public announcement that a person or group of affiliated or associated persons has acquired beneficial ownership of 15% or more of the outstanding shares of Software.com common stock, Software.com may redeem the rights in whole, but not in part, at a price of $0.001 per right. This right agreement will terminate on the earlier
(i) August 24, 2010, (ii) the date the rights are redeemed by Software.com and
(iii) the effective date of merger.

This rights agreement may have certain anti-takeover effects. The rights will cause substantial dilution to a person or group that attempts to acquire Phone.com in a manner not approved by Software.com's board of directors, except pursuant to an offer conditioned upon the negation, purchase or redemption of the rights.

UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL INFORMATION

Overview

On August 8, 2000, Phone.com entered into an agreement to merge with Software.com in a transaction expected to be accounted for as a pooling of interests. Under the terms of the agreement, each issued and outstanding share of Software.com common stock will be exchanged for 1.6105 shares of Phone.com common stock. In addition, all outstanding stock options and warrants of Software.com will be exchanged for Phone.com stock options and warrants based on the exchange ratio.

The following unaudited pro forma combined condensed financial statements reflect adjustments to the historical consolidated financial statements of Phone.com and Software.com to give effect to the merger using the pooling-of- interests method of accounting, and to certain other acquisitions of Phone.com and Software.com using purchase accounting as discussed below.

During the period from October 1999 through June 2000, Phone.com completed the acquisitions of APiON, AtMotion, Paragon, and Onebox in various transactions accounted for as purchases. Collectively, the companies acquired by Phone.com through June 2000 accounted for as purchases are referred to herein as the "Phone.com Acquired Entities."

During the period from October 1999 through June 2000, Software.com completed the acquisitions of Telarc and bCandid in transactions accounted for as purchases. Collectively, these companies acquired by Software.com through June 2000 accounted for as purchases are referred to herein as the "Software.com Acquired Entities."

Between April 1999 and April 2000, Software.com acquired two entities under separate transactions that were accounted for as poolings of interests. Accordingly, the historical financial statements of Software.com for all periods have been restated to give retroactive effect to these acquisitions.

The following unaudited pro forma combined condensed financial statements are presented for illustrative purposes only and are not necessarily indicative of the combined financial position or results of operations for future periods or the results of operations or financial position that actually would have been realized had Phone.com, Software.com, Phone.com Acquired Entities, and Software.com Acquired Entities been a combined company during the specified periods. The unaudited pro forma combined condensed financial statements, including the related notes, are qualified in their entirety by reference to, and should be read in conjunction with, the historical consolidated financial statements of Phone.com, Software.com, Phone.com Acquired Entities, and Software.com Acquired Entities, included elsewhere in this joint proxy statement/prospectus. The pro forma adjustments are preliminary and are based upon available information and certain assumptions that management of Phone.com and Software.com believe are reasonable.

The accompanying unaudited pro forma combined condensed balance sheet as of June 30, 2000, gives effect to the merger of Phone.com and Software.com as if such transaction occurred on June 30, 2000. The unaudited pro forma combined condensed balance sheet combines the consolidated balance of Phone.com as of June 30, 2000, with the consolidated balance sheet of Software.com as of June 30, 2000.

The accompanying unaudited pro forma combined condensed statements of operations presents the consolidated results of operations of Phone.com for the fiscal years ended June 30, 1998, 1999 and 2000, combined with the consolidated statements of operations of Software.com for the fiscal years ended December 31, 1998 and 1999, and the year ended June 30, 2000, respectively, as if Phone.com and Software.com had merged at the beginning of such periods. Additionally, the unaudited pro forma combined condensed statement of operations for the year ended June 30, 2000, reflects the acquisitions by Phone.com of the Phone.com Acquired Entities and the acquisitions by Software.com of the Software.com Acquired Entities as if such entities had been acquired on July 1, 1999.

On October 26, 1999, Phone.com completed its acquisition of APiON Telecom Limited, or APiON, a company based in Belfast, Northern Ireland, in exchange for 2,393,026 shares of its common stock. In addition, Phone.com also agreed to issue cash and common stock with an aggregate value of up to approximately $14.1 million to the then current and former employees of APiON. APiON was a provider of WAP software products to GSM network operators in Europe and had expertise in GSM Intelligent Networks, wireless data and WAP technology. Former employees of APiON received consideration totaling approximately $2.2 million in cash with the remaining $4.3 million payable in common stock of Phone.com on the one year anniversary of the closing of the acquisition of APiON subject to forfeiture upon the occurrence of certain events. Current employees of APiON received approximately $2.5 million in cash with the remaining $5.1 million payable in common stock of Phone.com on each of the first two anniversaries of the closing of the acquisition of APiON contingent upon continued employment. The actual number of Phone.com shares to be issued to the then current and former employees of APiON will depend upon the fair value of Phone.com common stock on the distribution date. The total purchase price for the transaction including direct acquisition costs was approximately $246.8 million.

Common stock issued to former shareholders and cash paid to current and former employees of APiON at the closing of the acquisition was included in the purchase price. Contingent common stock issuable in the future to former employees of APiON has been treated as contingent consideration. The common stock that is issued to the former employees of APiON upon the satisfaction of certain future events will be added to goodwill and amortized over the remaining useful life. Common stock issuable in the future to current employees of APiON has been recorded as deferred stock-based compensation.

The excess of the purchase price over the fair value of tangible net assets acquired amounted to approximately $244.5 million, with $242.5 million attributable to goodwill, $1.7 million attributable to assembled workforce, $170,000 attributable to developed technology and $110,000 attributable to in- process research and development. These assets are being amortized on a straight-line basis over a period of three years with the exception of the in- process research and development, which was expensed on the acquisition date. In connection with the acquisition, Phone.com recorded deferred stock-based compensation in the amount of approximately $5.1 million, which is being amortized on an accelerated basis over the vesting period of 24 months, consistent with the method described in FASB Interpretation No. 28.

PHONE.COM BUSINESS

Overview

Phone.com is a leading provider of software, applications, and services that enable the convergence of the Internet and wireless communications. Using Phone.com's software, network operators can provide Internet services to their wireless subscribers, and wireless telephone manufacturers can turn their mass-market wireless telephones into mobile Internet appliances. Wireless subscribers thus have access to Internet- and corporate intranet-based services, including e-mail, news, stocks, weather, travel and sports. In addition, subscribers have access via their wireless telephones to network operators' intranet-based telephony services, which may include over-the-air activation, call management, billing history information, pricing plan subscription and voice message management. Using Phone.com's software, network operators may also provide their subscribers with a unified mailbox for e- mail, voicemail, and fascimile.

Phone.com's software platform consists of the UP.Link Server, the Mobile Management Server, and the MyPhone Application Suite which are designed to be installed on network operators' systems. Phone.com's UP.Browser software is designed to be embedded in wireless telephones. As of June 30, 2000, 77 network operators have licensed Phone.com's software and have commenced or announced commercial service or are in market or laboratory trials. In addition, 35 wireless telephone manufacturers have licensed Phone.com's UP.Browser software, and UP.Browser has been ported to approximately 80 phone models.

Industry Background

Growth of the Internet and Wireless Telecommunications

Worldwide use of the Internet and wireless telecommunications has grown rapidly in the last few years. Current forecasts predict that rapid growth of both industries will continue. International Data Corporation, or IDC, estimates that there were approximately 261 million users of the Internet worldwide at the end of 1999 and that the number of users will grow to 623 million by the end of 2003. IDC estimates that there were approximately 395 million digital wireless subscribers worldwide at the end of 1999 and the number of subscribers will grow to approximately 1.3 billion by the end of 2003. Phone.com cannot assure you that these estimates will be achieved.

The Convergence of the Internet and Mobile Telephony

As people have become increasingly dependent on e-mail services, remote access to corporate intranets, and other Internet-based services, mass-market wireless telephones that provide mobile access to these resources have become increasingly useful tools. Phone.com was a pioneer in the convergence of the Internet and mobile telephony. In 1995, Phone.com developed its initial technology which enables the delivery of Internet-based services to wireless telephones. In 1996, Phone.com introduced and deployed its first products based on this technology.

To provide a worldwide open standard enabling the delivery of Internet-based services to mass-market wireless telephones, Phone.com co-founded the Wireless Application Protocol, or WAP, Forum. In 1998, the WAP Forum published technical specifications for application and content development and product interoperability based on Internet technology and standards. By complying with WAP specifications, wireless telephone manufacturers, network operators, content providers and application developers can provide Internet-based products and services that are interoperable.

In 1998, the WAP Forum published the Wireless Markup Language, or WML. WML is compliant with the Extensible Markup Language, or XML, specification published by the World Wide Web Consortium, or W3C. XML is a programming language that provides a means of describing and exchanging data in an open format. Content providers and application developers use WML to optimize the display of, and interaction with, Web-based data on wireless telephones. Based substantially on technology that Phone.com contributed to the public

94

domain, WML is optimized for delivery of Internet content to mass-market wireless telephones, which have numeric keypads instead of full keyboards, small screens, and limited memory capacity, processing power, battery life and bandwidth. In the same manner that the programming language known as Hypertext Markup Language, or HTML, has provided an open standard that has fueled the development of Internet applications and content for personal computers, WML is designed to be an industry standard that will encourage the development of Internet applications and content for wireless telephones.

The Market Opportunity

In response to an increasingly competitive environment, network operators are seeking to deliver Internet-based services to their wireless subscribers as a means to generate revenues from new sources, differentiate their service offerings, reduce subscriber turnover and operating costs, and unify offerings available to their wireless and wireline voice customers, and Internet portal users. To do this, network operators require a scalable software and services solution to deliver Internet-based services and content to their wireless and wireline subscribers.

The proliferation of Internet-standards based networks is rapidly altering the structure of the wireline and wireless network operator business. Operators which own wireless, wireline, portal and Internet service provider, or ISP, businesses are finding that they can achieve greater economies of scale by deploying common service platforms and applications across their various networks. Phone.com's MyPhone application suite and unified messaging application allow its customers such as British Telecom to offer common services across their wireless, wireline, and ISP businesses thereby improving their efficiency and overall economics of scale.

The Phone.com Solution

Phone.com provides platforms, applications and services that enable the delivery of Internet-based services to mass-market wireless telephones, personal computers and other mobile devices. Using Phone.com's scalable products, network operators can provide Internet-based content, applications and services to their wireless subscribers and offer common services across their wireless, wireline and ISP businesses. In addition, wireless telephone manufacturers can turn their mass-market wireless telephones into mobile Internet appliances. With Phone.com's technology, wireless subscribers have access to advanced communication services, Internet-based content and services and corporate intranet-based services; in addition, subscribers have the ability to use a single mailbox for wireless and wireline voice messages, e- mail and facsimiles. Existing carrier deployments, built on Phone.com's platform, include such services as unified messaging, e-mail, news, stock trading, weather, travel, sports, commerce, and calendaring.

Phone.com's solutions exhibit several characteristics valued by network and service operators:

. Innovative--Phone.com's products contain innovative features and functionality, and enable the network operator to provide valuable new services to their customers.

. Standards-based--Phone.com's products are based on industry standards, including those defined by WAP, W3C and the Internet Engineering Task Force, or IETF.

. Reliability--Phone.com's products are reliable, enabling the network operator to provide a high quality of service to their customers.

. Scalability--Phone.com's products have market-proven scalability into the millions of users, with high performance and reliability.

. Maturity--Phone.com's products are deployed in many networks, and have many features that make them desirable.

. Unity--Phone.com's products enable network operators to offer common services across their wireless, wireline and ISP businesses.

Phone.com's software platform consists of the UP.Link Server Suite, UP. Browser, Mobile Management Server, MyPhone Application Suite and FoneSync data synchronization software products.

95

UP.Link Server Suite

The UP.Link Server Suite includes:

. a means of exchanging data between the Internet and mass-market wireless telephones, commonly referred to as a gateway; and

. a service platform that performs subscriber management and service provisioning functions, and communicates with the network operator's customer care and billing systems.

UP. Browser

The UP.Browser is a browser and messaging software product that is designed and optimized for mass-market wireless telephones and other wireless devices.

Phone.com's Alliances Program is comprised of a select group of our content and application developers. Phone.com screens applications to its Alliances Program based on the availability and quality of the content or applications produced by the partner. Phone.com performs joint marketing activities with the partner, as well as provides introductions between its wireless network operators and its Alliances Program members.

Competition

The market for Phone.com's products and services continues to be competitive. The widespread adoption of open industry standards such as the WAP specifications may make it easier for new market entrants and existing competitors to introduce products that compete with Phone.com's software products. In addition, a number of Phone.com's competitors, including Nokia, have announced or are expected to announce enhanced features and functionality as proprietary extensions to the WAP protocol. Furthermore, some of Phone.com's competitors have introduced or may introduce services based on proprietary wireless protocols that are not compliant with the WAP specifications.

Phone.com expects that it will compete primarily on the basis of price, time-to-market, functionality, quality and breadth of product and service offerings. Phone.com's current and potential competitors include the following:

. Wireless equipment manufacturers, such as Ericsson and Nokia, which are developing and marketing competitive server, browser and application software products. These companies already sell billions of dollars worth of wireless telephones and other telecommunications products to network operators which are Phone.com's existing and potential customers.

. Microsoft, which has produced a wireless a version of its Mobile Explorer microbrowser to run on wireless handheld devices, including wireless telephones. This system is currently featured on handsets being marketed in the United Kingdom by Sony.

. Software companies, such as Oracle Corporation, which is marketing portal platform software that is compliant with the specifications promulgated by the WAP Forum. Oracle has additionally launched a separate Oracle Mobile division which supplies consumers with mobile information services.

. NTT DoCoMo, a customer of Phone.com through an agreement with its MID subsidiary, is pursuing a strategy to become a global wireless carrier. As part of this strategy, NTT DoCoMo, may seek to offer or sublicense its iMode service to other wireless service providers in a manner that would be competitive with the wireless Internet service offerings of Phone.com's customers.

106

With the expansion of Phone.com's MyPhone application suite to include such services as unified messaging, electronic messaging, personal information management software solutions and other advanced communications applications, Phone.com faces additional competitors. These competitors are varied as they individually touch various aspects of Phone.com's offerings. Competitors may include telecommunications messaging providers such as Comverse.

Many of Phone.com's existing competitors as well as potential competitors have substantially greater financial, technical, marketing and distribution resources than it does. Several of these companies also have greater name recognition and better established relationships with Phone.com's target customers. Furthermore, these competitors may be able to adopt more aggressive pricing policies and offer more attractive terms to customers than Phone.com can. Phone.com may face increasing price pressure from its network operator customers. In addition, current and potential competitors have established or may establish cooperative relationships among themselves or with third parties to compete more effectively. Finally, existing and potential competitors may develop enhancements to, or future generations of, competitive products that will have better performance features than Phone.com's products.

Intellectual Property Rights

Phone.com's performance depends significantly on its ability to protect its proprietary rights to the technologies used in its products. If Phone.com is not adequately protected, its competitors could use the intellectual property that Phone.com has developed to enhance their products and services, which could harm Phone.com's business. As of June 30, 2000, Phone.com had four issued United States patents. It also had six other United States patent applications containing allowed claims, and 79 pending United States patent applications. Phone.com has also filed corresponding foreign patent applications for approximately 50 of these United States patents and applications. In addition, Phone.com relies on a combination of copyright, trademark, trade secret laws, confidentiality provisions and other contractual provisions to protect its proprietary rights, but these legal means afford only limited protection. Despite any measures taken to protect its intellectual property, unauthorized parties may attempt to copy aspects of its products or to obtain and use information which it regards as proprietary. In addition, the laws of some foreign countries may not protect Phone.com's proprietary rights as fully as do the laws of the United States. Thus, the measures that Phone.com is taking to protect its proprietary rights in the United States and abroad may not be adequate. Finally, Phone.com's competitors may independently develop similar technologies.

The telecommunications and Internet software industries are characterized by the existence of a large number of patents and frequent litigation based on allegations of patent infringement. As the number of entrants into Phone.com's market increases, the possibility of an infringement claim against Phone.com grows. For example, Phone.com may be inadvertently infringing a patent of which it is unaware. In addition, because patent applications can take many years to issue, there may be a patent application now pending of which Phone.com is unaware, and which Phone.com may be accused of infringing when it issues in the future. To address any patent infringement claims, Phone.com may have to enter into royalty or licensing agreements on disadvantageous commercial terms. Phone.com may also have to incur significant legal expenses to ascertain the risk of infringing a patent and the likelihood of that patent being valid. A successful claim of patent infringement against Phone.com, and its failure to license the infringed or similar technology, would harm Phone.com's business. In addition, any infringement claims, with or without merit, would be time-consuming and expensive to litigate or settle and could divert management attention from administering Phone.com's core business.

Phone.com relies on a license of encryption technology from RSA Data Security, Inc. The license from RSA is perpetual unless terminated by either party as the result of a material breach or insolvency or, at Phone.com's election, for convenience.

As a member of several groups involved in setting standards for the industry, the WAP Forum, for example, Phone.com has agreed to license its intellectual property to other members of those groups on fair and reasonable terms to the extent that the intellectual property is essential to implementing the specifications promulgated by those groups. Each other member of the groups has entered into a reciprocal agreement.

107

Employees

As of June 30, 2000, Phone.com had a total of 875 employees. None of Phone.com's employees is covered by any collective bargaining agreements. Phone.com believes that its relations with its employees are good.

Properties

Phone.com's principal offices are located in Redwood City, California in four buildings aggregating 115,000 square feet under leases expiring in March and May of 2005. Phone.com has renewal options on two buildings for another five-year term. Phone.com's Belfast, Ireland office totals 20,000 square feet under a lease which expires in July 2014, with an option to terminate in 2009. Phone.com also leases space for our offices in London, Newbury, Copenhagen, Paris, Madrid, Rome, Mexico City, Hong Kong, Seoul and Tokyo.

In March 2000, Phone.com entered into a lease for approximately 280,000 square feet of office space in Redwood City, California, that is under construction and is expected to be completed in the year 2001. The lease is for a period of twelve years from the commencement date of the lease and has two five-year renewal options.

Legal Proceedings

In April 2000, Phone.com filed a lawsuit against Geoworks Corporation in the U.S. District Court in San Francisco California, alleging and seeking a court order declaring that U.S. Patent No. 5,327,529, assigned to Geoworks is not infringed by Phone.com and that the patent is also invalid and unenforceable. Phone.com took this action in response to Geoworks attempt to require industry participants to obtain licenses under the Geoworks patent. On June 15, 2000, Geoworks filed an answer to Phone.com's complaint and asserted a counterclaim against Phone.com alleging that it infringes the patent and seeking various forms of relief. Phone.com denies Geoworks' allegations and while it intends to pursue its position vigorously, the outcome of any litigation is uncertain, and it may not prevail. Additionally, it may incur substantial expenses in defending against this claim. Should Phone.com be found to infringe the Geoworks patent, Phone.com may be liable for potential monetary damages, and could be required to obtain a license from Geoworks. If Phone.com were unable to obtain a license on commercially reasonable terms, Phone.com may not be able to proceed with development and sale of some of Phone.com's products.

PHONE.COM'S MANAGEMENT DISCUSSION
AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

Overview

Phone.com was incorporated in December 1994 and, from inception until June 1996, its operations consisted primarily of various start-up activities, including development of technologies central to its business, recruiting personnel and raising capital. In 1995, Phone.com developed its initial technology, which enables the delivery of Internet-based services to wireless telephones. In 1996, Phone.com introduced and deployed its first products based on this technology. Phone.com first recognized license revenues in August 1996, and generated license revenues of approximately $522,000, $5.2 million and $43.7 million for the fiscal years ended June 30, 1998, 1999 and 2000, respectively. Phone.com incurred net losses of approximately $10.6 million, $20.8 million and $265.1 million for the fiscal years ended June 30, 1998, 1999 and 2000, respectively. Excluding amortization of goodwill and other intangibles, deferred stock compensation and charges for in-process research and development, Phone.com incurred net losses of approximately $10.5 million, $19.8 million and $22.8 million for the fiscal years ended June 30, 1998, 1999 and 2000, respectively. As of June 30, 2000, Phone.com had an accumulated deficit of approximately $307.1 million.

To provide a worldwide standard for the delivery of Internet-based services over mass-market wireless telephones, Phone.com co-founded the WAP Forum in 1997. In February 1998, the WAP Forum published technical specifications for application development and product interoperability based substantially on Phone.com's technology and on Internet standards. Leading network operators, telecommunications device and equipment manufacturers and software companies worldwide have sanctioned the specifications promulgated by the WAP Forum. In addition to the standard-setting process developed by the WAP Forum, Phone.com is also currently involved in development of a standard model for over-the-air provisioning and management of wireless devices through the CDG and also with the W3C for the development of future standards in the mobile web. Phone.com anticipates that the standards developed through these initiatives will continue to increase the acceptance of Internet-based services over wireless telephones.

Phone.com generates revenues from licenses, maintenance and support services and consulting services. Phone.com receives license revenues from licensing its software platform directly to network operators and indirectly through value-added resellers. Currently, Phone.com's software platform consists of the UP.Link Server, the Mobile Management Server and the MyPhone application suite. As of June 30, 2000, 77 network operators have licensed Phone.com's software and have commenced or announced commercial service or are in market or laboratory trials. Those customers serve over 240 million voice subscribers. Maintenance and support services revenues are from engineering and support services provided to wireless telephone manufacturers and wireless network operators. Consulting services revenues are derived from consulting services provided to network operator customers either directly by Phone.com or indirectly through resellers.

Phone.com's future success depends on its ability to increase revenues from sales of products and services to new and existing network operator customers. If the market for Internet-based services via wireless telephones fails to develop or develops more slowly than expected, then Phone.com's business would be materially and adversely affected. In addition, because there is a relatively small number of network operators worldwide, any failure to sell Phone.com's products to network operator customers successfully could result in a shortfall in revenues that could not be readily offset by other revenue sources.

Phone.com's business strategy also relies to a significant extent on the widespread propagation of UP.Browser-enabled telephones through its relationships with network operators and wireless telephone manufacturers. In order to encourage adoption of UP.Browser-enabled wireless telephones, Phone.com generally licenses its UP.Browser software to wireless telephone manufacturers free of per-unit royalties and other license fees and provide maintenance and support services for an annual flat fee. As of June 30, 2000, Phone.com had licensed UP.Browser to 35 wireless telephone manufacturers.

109

Effective July 1, 1998, Phone.com adopted SOP 97-2, Software Revenue Recognition, as amended by SOP 98-4 and SOP 98-9. SOP 97-2, as amended, generally requires revenue earned on software arrangements involving multiple elements to be allocated to each element based on the relative fair value of the elements.

Phone.com licenses its UP.Link Server Suite and related server-based software products to network operators through its direct sales force and indirectly through its channel partners. Phone.com's license agreements do not provide for a right of return. Allowances for future estimated warranty costs are provided at the time revenue is recognized. Licenses can be purchased under a perpetual license model either on an as-deployed or on a prepaid basis, or alternatively, under a monthly or quarterly time-based license model under which no perpetual license is acquired. For licenses purchased on an as- deployed basis, license revenue is generally recognized quarterly as subscribers are activated to use the services that are based on Phone.com's UP.Link Server Suite and related server-based software products. For licenses purchased on a prepaid basis, prepaid license fees are recognized ratably over the period that maintenance and support services are expected to be provided unless Phone.com committed to provide the customer with future unspecified products under a subscription arrangement. Under a subscription arrangement, prepaid license fees are recognized ratably over the contractual term of the prepaid arrangement (i.e., the date the prepaid licenses expire if not used), generally 12 to 30 months, commencing at the beginning of the month delivery and acceptance occur by the network operator. Phone.com recognizes revenues from its other prepaid licenses, including the related maintenance and support services provided to network operators, ratably over the lesser of the estimated life of the software or the contractual term of the arrangement, generally 12 to 30 months, commencing at the beginning of the month delivery and acceptance occur by the network operator. For customers that license Phone.com's products under the time-based license model, revenues are recognized over the respective period based on the number of the customer's subscribers using the services that are based on Phone.com's products. Revenues from consulting services provided to network operators are recognized as the services are performed.

Phone.com recognizes revenues from UP.Browser agreements with wireless telephone manufacturers ratably over the period during which the services are performed, generally one year. Phone.com provides its wireless telephone manufacturer customers with support associated with their efforts to port its UP.Browser software to their wireless telephones, software error corrections, and new releases as they become commercially available.

Deferred revenue increased from $36.8 million as of June 30, 1999 to $77.3 million as of June 30, 2000. Deferred revenue as of June 30, 2000, was comprised of $72.9 million in prepaid fees charged to wireless network operators and $4.4 million in prepaid maintenance and other service fees charged to wireless telephone manufacturers. Despite the year over year increase in deferred revenue, Phone.com expects that deferred revenue will decline in the long term as network operators deploy services based on its products. Deferred revenues relating to prepayments by wireless network operators as of June 30, 2000, in the amount of approximately $68.8 million will be recognized over the next fifteen months. The remainder of deferred revenues relating to wireless network operators will generally be recognized over the next 12 to 30 months.

Phone.com expects that its gross profit on revenues derived from sales through indirect channel partners will be less than the gross profit on revenues from direct sales. Phone.com's success, in particular in international markets, depends in part on its ability to increase sales of its products and services through value-added resellers and to expand its indirect distribution channels. In addition, Phone.com's agreements with its distribution partners generally do not restrict the sale of products that are competitive with its products and services, and each of Phone.com's partners can cease marketing Phone.com's products and services at their option.

International sales of products and services accounted for 48%, 68% and 73% of Phone.com's total revenues in the years ended June 30, 1998, 1999 and 2000, respectively. Phone.com expects international sales to continue to account for a significant portion of its revenues, although the percentage of Phone.com's total revenues derived from international sales may vary. In particular, a number of manufacturers have delayed commercial release of WAP-compliant wireless telephones, particularly affecting European and other markets based on the GSM standard. Risks inherent in Phone.com's international business activities, include:

. failure by Phone.com and/or third parties to develop localized content and applications that are used with its products;

110

. costs of localizing Phone.com's products for foreign markets;

. difficulties in staffing and managing foreign operations;

. longer accounts receivable collection time;

. political and economic instability;

. fluctuations in foreign currency exchange rates;

. protection of intellectual property rights in some foreign countries;

. contractual provisions governed by foreign laws;

. export restrictions on encryption and other technologies;

. potentially adverse tax consequences; and

. the burden of complying with complex and changing regulatory requirements.

Since early 1997, Phone.com has invested substantially in research and development, marketing, domestic and international sales channels, professional services and its general and administrative infrastructure. These investments have significantly increased Phone.com's operating expenses, contributing to net losses in each fiscal quarter since its inception. Phone.com's limited operating history makes it difficult to forecast future operating results. Although Phone.com's revenues have grown in recent quarters, its revenues may not increase at a rate sufficient to achieve and maintain profitability, if at all. Phone.com anticipates that its operating expenses will increase substantially in absolute dollars for the foreseeable future as it expands its product development, sales and marketing, professional services and administrative staff. Even if Phone.com was to achieve profitability in any period, it may not sustain or increase profitability on a quarterly or annual basis.

Acquisitions

On October 26, 1999, Phone.com completed its acquisition of APiON Telecoms Limited, or APiON, a company based in Belfast, Northern Ireland, in exchange for 2,393,026 shares of its common stock. In addition, Phone.com also agreed to issue cash and common stock with an aggregate value of up to approximately $14.1 million to current and former employees of APiON. APiON was a provider of WAP software products to GSM network operators in Europe and had expertise in GSM Intelligent Networks, wireless data and WAP technology. Former employees of APiON received consideration totaling approximately $2.2 million in cash with the remaining $4.3 million payable in common stock of Phone.com on the one-year anniversary of the closing of the acquisition of APiON subject to forfeiture upon the occurrence of certain events. Current employees of APiON received approximately $2.5 million in cash with the remaining $5.1 million payable in common stock of Phone.com on each of the first two anniversaries of the closing of the acquisition of APiON contingent upon continued employment. The actual number of Phone.com shares to be issued to the then current and former employees of APiON will depend upon the fair value of Phone.com common stock on the distribution date. The total purchase price for the transaction including direct acquisition costs was approximately $246.8 million.

Common stock issued to former shareholders and cash paid to current and former employees of APiON at the closing of the acquisition was included in the purchase price. Contingent common stock issuable in the future to former employees of APiON has been treated as contingent consideration. The common stock that is issued to the former employees of APiON upon the satisfaction of certain future events will be added to goodwill and amortized over the remaining useful life, which may increase Phone.com's losses in future periods. Common stock issuable in the future to current employees of APiON has been recorded as deferred stock-based compensation.

Phone.com accounted for the acquisition of APiON as a purchase with APiON's results of operations included from the acquisition date. The excess of the purchase price over the fair value of tangible net assets acquired amounted to approximately $244.5 million, with $242.5 million attributable to goodwill, $1.7 million attributable to assembled workforce, $170,000 attributable to developed technology and $110,000 attributable to in-process research and development. These assets are being amortized on a straight-line basis over a period of three years with the exception of the in-process research and development, which was expensed on the acquisition date. In connection with the acquisition, Phone.com recorded deferred stock-based compensation in the amount of approximately $5.1 million, to be amortized over a two-year period.

111

On October 27, 1999, Phone.com acquired substantially all of the assets of Angelica Wireless ApS, or Angelica, including all software technology, intellectual property and certain customer agreements, and excluding the assumption of liabilities. Angelica is a developer of WAP software products complementary to Phone.com's MyPhone mobile Internet portal software. Total consideration paid, including direct acquisition costs, was approximately $2.0 million. In addition, Phone.com also agreed to issue approximately 16,000 shares of its common stock to employees of Angelica with an aggregate value of approximately $1.7 million, subject to certain forfeiture conditions dependent on continued employment. Phone.com accounted for the acquisition as a purchase with Angelica's results of operations included from the acquisition date. Approximately $2.0 million was allocated to goodwill, which is being amortized on a straight line basis over a period of three years. In addition, Phone.com recorded deferred stock-based compensation in the amount of approximately $1.7 million, which is being amortized on an accelerated basis over the vesting period of 36 months.

On February 8, 2000, Phone.com acquired all of the outstanding common and redeemable convertible preferred stock of AtMotion, Inc., or AtMotion, in exchange for 2,280,287 shares of its common stock. Phone.com also assumed all of the outstanding options and warrants of AtMotion. AtMotion is a provider of Voice Portal technology. Total consideration paid was approximately $287.2 million. The acquisition was accounted for as a purchase with AtMotion's results of operations included from the acquisition date. The excess of the purchase price over the fair value of tangible net assets acquired amounted to approximately $286.1 million, with $242.9 million attributable to goodwill, $655,000 attributable to assembled workforce and $42.5 million attributable to developed technology. These assets are being amortized on a straight-line basis over a period of three years. Phone.com expects to incur significant additional expenses in developing, integrating and commercializing the acquired technology, as well as sales and marketing and research and development expenses. Phone.com expects to incur these costs and expenses in advance of generating revenues and cannot be certain that its business model for the incorporation of the AtMotion technology will result in significant revenues or profitability.

On March 4, 2000, Phone.com acquired all of the outstanding common and convertible preferred stock of Paragon Software (Holdings) Limited, or Paragon, a company incorporated in England and Wales, in exchange for 3,051,016 shares of its common stock. Phone.com also assumed all of the outstanding options of Paragon. Paragon is a provider of synchronization technology allowing PC-based personal information to be easily transferred to mobile devices. Phone.com plans to extend the Paragon technology to WAP-based over-the-air synchronization to meet phone users' needs for simpler synchronization of information between the mobile phone, PC applications, and Internet information services, whether or not the phone users are on-line. Total consideration paid was approximately $453.7 million in common stock of Phone.com in addition to a cash payment of $3.6 million. Additional cash payments of approximately $3.9 million will be allocated among certain employees of Paragon within one year of the acquisition. There were also transaction costs in connection with the purchase of approximately $11.6 million. The acquisition was accounted for as a purchase with Paragon's results of operations included from the date of acquisition. The excess of the purchase price over the fair value of tangible net assets acquired amounted to approximately $483.7 million, with $455.1 million attributable to goodwill, $980,000 attributable to assembled workforce, $7.2 million attributable to developed technology, $2.3 million attributable to non-compete agreements and $18.1 million attributable to in-process research and development. These assets are being amortized on a straight-line basis over a period of three years, except for the in-process research and development, which was expensed on the acquisition date. In addition, Phone.com expects to incur significant additional expenses in developing, integrating and commercializing the acquired technology, as well as sales and marketing and research and development expenses. Phone.com expects to incur these costs and expenses in advance of generating revenues and cannot be certain that its business model for the incorporation of the Paragon technology will result in significant revenues or profitability. On August 11, 2000, the Company accelerated a cash payment of $17.0 million to a former shareholder of Paragon that was originally due one year from the original purchase date of March 4, 2000. The payment was accelerated in conjunction with the former shareholder's separation from Phone.com.

On April 14, 2000, Phone.com acquired all of the outstanding common and preferred stock of Onebox.com, Inc., or Onebox, a wireless communications application service provider offering users unified e-mail, voicemail

112

and fascimile, in exchange for 6,207,865 shares of Phone.com common stock. Phone.com also assumed all of the outstanding options of Onebox, which is based in San Mateo, California. Total consideration paid was approximately $814.7 million including estimated transaction costs of approximately $16.8 million. The acquisition was accounted for as a purchase with Onebox's results of operations included from the date of acquisition. The excess of the purchase price over the fair value of tangible net assets acquired amounted to approximately $814.1 million, with $789.7 million attributable to goodwill, $590,000 attributable to assembled workforce, $14.7 million attributable to developed technology, $4.8 million attributable to non-compete agreements and $4.3 million attributable to in-process research and development. These assets are being amortized on a straight-line basis over a period of three years, except for the amount recorded for in-process research and development, which was expensed on the acquisition date. In addition, while the technology that it acquired as a result of Phone.com's Onebox acquisition now forms a part of its MyPhone application suite, Phone.com expects to continue to incur significant sales and marketing expenses in advance of generating significant revenues and cannot be assured that the incorporation of the Onebox technology will result in significant revenues or profitability.

On May 4, 2000, Phone.com acquired all of the outstanding common stock of Velos 2 S.r.l., or Velos, a company based in Milan, Italy, in exchange for 8,134 shares of Phone.com common stock valued at approximately $579,000 plus a cash payment and direct transaction costs totaling approximately $350,000. The acquisition was accounted for as a purchase with Velos' results of operations included from the date of acquisition. Approximately $929,000 was allocated to goodwill, which is being amortized on a straight-line basis over a period of three years. In addition, Phone.com issued an additional 9,866 shares of its common stock contingent on future employment, which resulted in deferred stock-based compensation in the amount of approximately $1.2 million, to be amortized over a three-year period.

On June 14, 2000, Phone.com acquired all of the outstanding common stock of MyAble, Inc., or MyAble, a company based in Palo Alto, California, in exchange for 193,873 shares of Phone.com common stock. Phone.com also assumed all of the outstanding options of MyAble. MyAble is a provider of hosted personalization services for wireline and wireless web technologies. Total consideration paid was approximately $18.4 million. The acquisition was accounted for as a purchase with MyAble's results of operations included from the date of acquisition. Approximately $18.4 million was allocated to goodwill, which is being amortized on a straight-line basis over a period of three years.

The amount expensed to purchased research and development in the fiscal year ended June 30, 2000 arose from the purchase acquisitions of Paragon and Onebox.

At the time of the acquisitions, the estimated aggregate fair value of Paragon's and Onebox's research and development efforts that had not reached technological feasibility as of the acquisition date and, as of that date, had no alternative future uses was estimated to be approximately $18.1 million and $4.3 million, respectively, and was expensed at the date of acquisition. This allocation represented the estimated fair value based on risk-adjusted cash flows related to incomplete research and development projects. Paragon and Onebox each had one project considered to be in-process technology at the time of the acquisitions.

These projects were for Paragon's over-the-air synchronization product, which would allow a user to synchronize information between their PIM, cellular phone and PDA devices at the touch of a button without requiring the use of a cord or other linking device, and Onebox's productization of integrated messaging services for wireless and wireline telecommunications providers, ISP's and Web-based businesses. The products of Paragon and Onebox are due for completion in Phone.com's fiscal 2001 period.

The percentage completion of these projects at the time of acquisition were as follows:

Over-the-air synchronization product..................................... 40%
Productization of integrated messaging service........................... 77%

113

The fair value assigned to purchased in-process technology was determined by estimating the completion percentage of research and development efforts at the acquisition date, forecasting risk-adjusted revenues considering the completion percentage, estimating the resulting net cash flows from the projects and discounting the net cash flows to their present value. The completion percentages were estimated based on cost incurred to date, importance of completed development tasks and the elapsed portion of the total project time.

The revenue projection used to value the in-process research and development is based on units sales forecasts for worldwide sales territories and adjusted to consider only the revenue related to development achievements completed at the acquisition date. Projected annual revenues for the in-process development projects were assumed to increase from product release through 2003 and decline significantly in 2004.

Gross profit for the over-the-air synchronization project was assumed to be 84% in 2001 and between 81% and 85% from 2002 through 2004. Gross profit for the productization of the integrated messaging service project was assumed to be 68% in 2000 and between 87% and 89% from 2001 through 2002. These projections were based on previous experience with similar products.

Estimated operating expenses, income taxes and capital charges to provide a return on other acquired assets were deducted from gross profit to arrive at net operating income for the in-process development projects. Operating expenses were estimated as a percentage of revenue and included sales and marketing expenses, administrative expenses, and development costs to maintain the technology once it has achieved technological feasibility. In addition, net cash flows estimates were adjusted to allow for fair return on working capital and fixed assets. For Paragon, a 25% discount rate was used to discount the net cash flows back to their present value. For Onebox, a 22% discount rate was used to discount the net cash flows back to their present value. If these projects are not successfully developed, Phone.com may not realize the value assigned to the in-process research and development projects. Total estimated costs to complete Paragon's project as of the acquisition date was approximately $395,000. Total estimated costs to complete Onebox's project as of the acquisition date was approximately $1.1 million.

Fiscal Years Ended June 30, 1998, 1999 and 2000

License Revenues

License revenues increased from $522,000 in the fiscal year ended June 30, 1998 to $5.2 million in the fiscal year ended June 30, 1999, and $43.7 million in the fiscal year ended June 30, 2000. The increase in license revenues was due primarily to the launch of wireless Internet-based services by an increasing number of network operators. The increase in license revenues in fiscal 2000 was due primarily to the launch by Omnitel, Sprint and other wireless network operators in the United States as well as the ongoing satisfaction of Phone.com's deployment obligations related to AT&T. In total, Phone.com recognized license revenues from approximately 50 wireless network operator customers in North America, Europe, Asia and other parts of the world.

Maintenance and Support Services Revenues

Maintenance and support services revenues increased from $1.7 million in the fiscal year ended June 30, 1998 to $5.9 million in the fiscal year ended June 30, 1999, and $14.5 million in the fiscal year ended June 30, 2000. The increase in maintenance and support services revenues reflects an increase in services provided to wireless telephone manufacturers and increased installation and support fees from network operators. Of the increase from fiscal 1999 to fiscal 2000, approximately $6.6 million was attributable primarily to increased demand for maintenance and engineering support services by wireless telephone manufacturers, and approximately $2.0 million was attributable to maintenance and support services provided to wireless network operators.

Consulting Services Revenues

Consulting services revenues increased from $2.3 million for the fiscal year ended June 30, 1999 to $10.5 million for the fiscal year ended June 30, 2000. The increase in consulting services revenues was primarily due

114

to the increased number of wireless network operators who have licensed Phone.com's technology and engaged Phone.com to perform integration services relating to their commercial launches of its technology. No consulting services revenues were earned in the fiscal year ended June 30, 1998.

Cost of License Revenues

Cost of license revenues consists primarily of third-party license and support fees. Cost of license revenues increased from $95,000 in the fiscal year ended June 30, 1998 to $371,000 in the fiscal year ended June 30, 1999, and $4.2 million in the fiscal year ended June 30, 2000. As a percentage of license revenues, cost of license revenues in the fiscal years ended June 30, 1998, 1999 and 2000 was 18%, 7% and 10%, respectively. The decrease as a percentage of license revenues for fiscal 1999 was attributable primarily to higher license revenues for fiscal 1999 and to the amortization of fixed maintenance fees relating to third party software licenses. The cost of license revenues increased for the fiscal year ended June 30, 2000 as a percentage of license revenues due to the acquisition of Onebox and the inclusion of its costs associated with the operation of its data center in cost of license revenues under the ASP model. Under an ASP model, certain costs such as the depreciation costs associated with operating a data center are charged to cost of license revenues. Phone.com expects that cost of license revenues will continue to vary as a percentage of license revenues from period to period.

Cost of Maintenance and Support Services Revenues

Cost of maintenance and support services revenues consists of compensation and related overhead costs for personnel engaged in the delivery of installation, training and support services to network operators and engineering and support services to wireless telephone manufacturers. The engineering and support services performed for wireless telephone manufacturers include assistance relating to integrating Phone.com's UP.Browser software into the manufacturers' wireless telephones. Cost of maintenance and support services revenues increased from $1.1 million in the fiscal year ended June 30, 1998 to $3.0 million in the fiscal year ended June 30, 1999, and $10.4 million in the fiscal year ended June 30, 2000. As a percentage of maintenance and support services revenues, cost of maintenance and support services revenues in the fiscal years ended June 30, 1998, 1999 and 2000 was 63%, 51% and 72%, respectively. The margin decrease associated with the growth in cost of maintenance and support services revenues from the fiscal year ended June 30, 1999 to the fiscal year ended June 30, 2000, was attributable primarily to an increase in personnel dedicated to support a larger number of wireless telephone manufacturer customers and to increased staffing in anticipation of growth in the number of network operator customers. Gross profit on maintenance and support services increased from fiscal 1998 to fiscal 1999 due to the increase in the number of browser integration assignments for wireless telephone manufacturers, which had the effect of spreading our costs over a greater revenue base. In addition, the number of trials in progress by network operators increased during this period. Phone.com anticipates that the cost of maintenance and support services revenues will increase in absolute dollars in future operating periods.

Cost of Consulting Services Revenues

Cost of consulting services revenues consists of compensation and independent consultant costs for personnel engaged in Phone.com's consulting services operations and related overhead. Cost of consulting services revenues increased from $1.1 million in the fiscal year ended June 30, 1999 to $6.2 million in the fiscal year ended June 30, 2000. No consulting services were performed in fiscal year 1998. As a percentage of consulting services revenues, cost of consulting services revenues in the fiscal years ended June 30, 1999 and 2000 were 50% and 59%, respectively. The decrease in gross margins associated with consulting services revenues was due to a higher mix of consulting services performed on a time and materials basis compared to the services Phone.com performs under fixed contractual arrangements. Gross profit on consulting services revenues is impacted by the mix of company personnel and independent consultants assigned to projects. The gross profit Phone.com achieves is also impacted by the contractual terms of the consulting assignments Phone.com undertakes, and the gross profit on fixed price contracts typically is more susceptible to fluctuation than contracts performed on a time-and-materials basis. Phone.com anticipates that the cost of consulting services revenues will increase in absolute dollars as it continues to invest in the growth of its consulting operations.

115

Research and Development Expenses

Research and development expenses consist primarily of compensation and related costs for research and development personnel. Research and development expenses increased 128% from $5.7 million in the fiscal year ended June 30, 1998 to $13.1 million in the fiscal year ended June 30, 1999 and increased 190% to $38.0 million in the fiscal year ended June 30, 2000. The increases in research and development expenses were attributable primarily to the addition of personnel in Phone.com's research and development organization associated with product development. Phone.com expects to continue to make substantial investments in research and development and anticipates that research and development expenses will increase in absolute dollars. Phone.com further anticipates that research and development expenses will increase substantially due to product development efforts associated with all of Phone.com's initiatives, including Unified Messaging. Phone.com has also added a significant numbers of engineering personnel through its acquisitions of APiON, Angelica, AtMotion, Paragon, Onebox and MyAble.

Sales and Marketing Expenses

Sales and marketing expenses consist primarily of compensation and related costs for sales and marketing personnel, sales commissions, marketing programs, public relations, promotional materials, travel expenses and trade show exhibit expenses. Sales and marketing expenses increased 116% from $5.0 million in the fiscal year ended June 30, 1998 to $10.8 million in the fiscal year ended June 30, 1999 and increased 243% to $37.2 million in the fiscal year ended June 30, 2000. These increases resulted from the addition of personnel in Phone.com's sales and marketing organizations, reflecting its increased selling effort to develop market awareness of its products and services. Phone.com anticipates that sales and marketing expenses will increase in absolute dollars as it increases its investment in these areas. In addition, Phone.com expects that sales and marketing expenses will increase as a result of the addition of sales and marketing personnel in connection with the acquisitions of APiON, AtMotion, Paragon, Onebox, Velos and MyAble.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and related expenses, accounting, legal and administrative expenses, professional service fees and other general corporate expenses. General and administrative expenses increased 146% from $1.8 million in the fiscal year ended June 30, 1998 to $4.4 million in the fiscal year ended June 30, 1999 and increased 204% to $13.5 million in the fiscal year ended June 30, 2000. The increases were due primarily to the addition of personnel performing general and administrative functions, additional expenses in connection with Phone.com's operation as a public company and, to a lesser extent, legal expenses associated with increased product licensing and patent activity. Phone.com expects general and administrative expenses to increase in absolute dollars as it adds personnel and incurs additional expenses related to the anticipated growth of its business, the management of its international operations, and its operation as a public company.

Stock-Based Compensation

Stock-based compensation expense totaled $108,000, $1.0 million and $5.5 million for the fiscal years ended June 30, 1998, 1999 and 2000, respectively. All stock-based compensation is being amortized in a manner consistent with Financial Accounting Standards Board Interpretation No. 28. Some stock options granted and restricted stock issued during the fiscal years ended June 30, 1998, 1999, and 2000, resulted in the recognition of deferred stock-based compensation. Total deferred stock-based compensation associated with these equity arrangements amounted to $2.4 million related to stock options granted and restricted stock issued from October 1997 through June 1999. Of the total deferred stock-based compensation recorded through June 1999, $108,000, $1.0 million, and $696,000 was amortized in the fiscal years ended June 30, 1998, 1999 and 2000, respectively. In November 1999, a stock option award was made to a new employee at a price discounted from the then-current fair market value of Phone.com's stock, giving rise to deferred stock-based compensation in the amount of $2.8 million. For the year ended June 30, 2000, Phone.com recognized stock-based compensation expense

116

related to this award in the amount of $1.3 million. Phone.com expects amortization of approximately $1.3 million, $600,000 and $300,000 in the fiscal years ending June 30, 2001, 2002 and 2003, respectively, relating to the amortization of the deferred stock-based compensation associated with stock options granted and restricted stock issued from October 1997 through June 2000.

In connection with its acquisition of APiON in October 1999, Phone.com recorded additional deferred stock-based compensation of approximately $5.1 million. For the year ended June 30, 2000, Phone.com recognized stock-based compensation expense related to APiON in the amount of $2.6 million, and it expects amortization of approximately $2.1 million and $400,000 in the fiscal years ending June 30, 2001 and 2002, respectively. In connection with its acquisition of Angelica in October 1999, Phone.com recorded additional deferred stock-based compensation of approximately $1.7 million. For the year ended June 30, 2000, Phone.com recognized stock-based compensation expense related to Angelica in the amount of $818,000, and expects amortization of approximately $700,000 and $200,000 in the fiscal years ending June 30, 2001 and 2002, respectively. In connection with its acquisition of Velos in June 2000, Phone.com recorded additional deferred stock-based compensation of approximately $1.2 million. For the year ended June 30, 2000, Phone.com recognized stock-based compensation expense related to Velos in the amount of $145,000, and it expects amortization of approximately $800,000 and $300,000 in the fiscal years ending June 30, 2001 and 2002, respectively. Phone.com may in the future issue stock options with exercise prices below the then fair market value, which would increase deferred stock-based compensation.

Amortization of Goodwill and Other Intangible Assets and In-Process Research and Development

Amortization of goodwill and intangible assets relating to Phone.com's October 1999 acquisitions of APiON and Anglica and its acquisitions of AtMotion in February 2000, Paragon in March 2000, Onebox in April 2000, Velos in May 2000 and MyAble in June 2000 aggregated $214.4 million for the year ended June 30, 2000. In connection with the APiON acquisition, Phone.com recorded goodwill and other intangible assets of approximately $244.4 million, which is being amortized on a straight-line basis over a three-year period. Phone.com also recorded an immediate expense of $110,000 relating to in- process research and development in connection with the APiON acquisition. In connection with the Angelica acquisition, Phone.com recorded goodwill of approximately $2.0 million, which is being amortized on a straight-line basis over a three-year period. In connection with the AtMotion acquisition, Phone.com recorded goodwill and other intangible assets of approximately $286.1 million, which is being amortized on a straight-line basis over a three-year period. In connection with the Paragon acquisition, Phone.com recorded goodwill and other intangible assets of approximately $465.6 million, which is being amortized on a straight-line basis over a three-year period. Phone.com also recorded an immediate expense of $18.1 million relating to in- process research and development in connection with the Paragon acquisition. In connection with the Onebox acquisition, Phone.com recorded goodwill and other intangible assets of approximately $809.8 million, which is being amortized on a straight-line basis over a three-year period. Phone.com also recorded an immediate expense of $4.3 million relating to in-process research and development in connection with the Onebox acquisition. In connection with the Velos acquisition, Phone.com recorded goodwill of approximately $929,000, which is being amortized on a straight-line basis over a three-year period. In connection with the MyAble acquisition, Phone.com recorded goodwill of approximately $18.4 million, which is being amortized on straight-line basis over a three-year period. Phone.com expects amortization of approximately $609.1 million, $609.1 million and $394.8 million in the fiscal years ending June 30, 2001, 2002 and 2003, respectively, relating to the amortization of goodwill and other intangible assets. In addition, Phone.com may have additional acquisitions in future periods, which could give rise to additional goodwill or other intangible assets being acquired. If Phone.com acquires additional goodwill or other intangible assets, its acquisition-related amortization may increase in future periods.

Interest Income, Net

Net interest income was $982,000, $1.8 million and $19.6 million in the fiscal years ended June 30, 1998, 1999, and 2000, respectively. The year-to- year increases resulted primarily from earnings on rising cash, cash

117

equivalent, and short-term investment balances as a result of Phone.com's private placement financings in February 1998 and March 1999, its initial public offering in June 1999, and its secondary public offering in November 1999, partially offset in the fiscal years ended June 30, 1998, 1999, and 2000 by interest expense related to obligations under capital leases and Phone.com's equipment loan.

Income Taxes

Income tax expense of $2.1 million and $1.6 million for the fiscal years ended June 30, 1999 and 2000, consisted of foreign withholding taxes. Since its inception, Phone.com has incurred net losses for federal and state tax purposes and has not recognized any tax provision or benefit. As of June 30, 2000, Phone.com had net operating loss carryforwards for federal and California income tax purposes of approximately $192 million and $96 million, respectively. In addition, Phone.com has federal and California research and development credit carryforwards of approximately $4.9 million and $3.9 million, respectively. The federal net operating loss carryforwards and research and development credit carryforwards will expire from 2011 through 2020 if not utilized. The California net operating loss carryforwards will expire from 2004 through 2006 if not utilized. The California research and development credit carryforwards can be carried forward indefinitely. Federal and California tax laws impose significant restrictions on the utilization of net operating loss carryforwards in the event of a change in Phone.com's ownership that constitutes an "ownership change," as defined in Section 382 of the Internal Revenue Code. If Phone.com has an ownership change, the ability to utilize the stated carryforwards could be significantly reduced. The merger with Software.com may result in an ownership change.

As of June 30, 2000, Phone.com had net deferred tax assets of $63.9 million, which were fully offset by a valuation allowance. Deferred tax assets consist principally of the federal and state net operating loss carryforwards, start- up expenditures capitalized for tax purposes, accruals and reserves not currently deductible for tax purposes, research and development credits, and foreign tax credit carryforwards. Deferred tax liabilities resulted from Phone.com's acquisitions during the year ended June 30, 2000, due to a difference in the financial statement and tax basis of net assets acquired. In addition, Phone.com has provided a valuation allowance due to the uncertainty of generating future profits that would allow for the realization of these deferred tax assets. Accordingly, no tax benefit was recorded in the accompanying consolidated statements of operations.

Approximately $49.2 million of the valuation allowance for deferred tax assets relating to net operating loss carryforwards is attributable to employee stock option deductions, the benefit from which will be allocated to additional paid-in capital when and if subsequently realized. The benefit from approximately $5.8 million of the total $7.5 million valuation allowance for the deferred tax asset related to research and development credit carryforwards will be allocated to additional paid-in capital when and if subsequently realized.

Liquidity and Capital Resources

Since its inception, Phone.com has financed its operations through private sales of convertible preferred stock, which totaled $66.0 million in aggregate net proceeds through March 31, 1999, through its initial public offering in June 1999, which generated net proceeds of approximately $66.8 million, and through its secondary public offering in November 1999, which generated net proceeds of approximately $390.4 million. As of June 30, 2000, Phone.com had $435.6 million of cash, cash equivalents, and short-term investments and working capital of $356.8 million.

Net cash used for operating activities was $5.1 million, $917,000, and $1.4 million for the fiscal years ended June 30, 1998, 1999, and 2000, respectively. For each of the fiscal years ended June 30, 1998, 1999, and 2000, cash used for operating activities was attributable primarily to net losses and an increase in accounts receivable offset in part by non-cash expenses such as acquisition-related amortization charges and depreciation, increases in accounts payable and accrued liabilities, and increases in deferred revenue. For the fiscal year ended June 30, 2000, accounts receivable increased by approximately $22.3 million. This increase was due to increased sales to both wireless telephone manufacturers and network operators. Accrued liabilities increased by approximately

118

$8.7 million for the fiscal year ended June 30, 2000, excluding acquisition- related accruals. Deferred revenue increased by approximately $38.5 million for the fiscal year ended June 30, 2000, primarily as a result of increased deferred license prepayments by network operators.

Net cash used for investing activities was $18.0 million, $15.2 million, and $396.2 million for the fiscal years ended June 30, 1998, 1999, and 2000, respectively. For the fiscal year ended June 30, 2000, Phone.com's primary use of cash was for increased purchases of short-term and restricted investments in the amount of $544.6 million, partially offset by the sale of short-term investments in the amount of $200.1 million. Phone.com also continued to make investments in property and equipment in the amount of $20.1 million and used $31.6 million of cash as part of the cost of acquiring APiON, Angelica, AtMotion, Paragon, Onebox, Velos, and MyAble.

Net cash provided by financing activities was $31.7 million, $83.2 million, and $396.9 million for the fiscal years ended June 30, 1998, 1999, and 2000, respectively. Cash provided by financing activities in fiscal years 1998 and 1999 was primarily attributable to proceeds from the issuance of preferred stock. In addition, in June 1999, Phone.com completed an initial public offering of 9,200,000 shares of its common stock at a public offering price of $8.00 per share, which resulted in net proceeds to Phone.com of approximately $66.8 million. In November 1999, Phone.com completed a secondary public offering of 3,041,500 shares of its common stock at a public offering price of $135.00 per share, which resulted in net proceeds to Phone.com of approximately $390.4 million. All of the outstanding shares of convertible preferred stock were automatically converted into shares of common stock upon the closing of the initial public offering in June 1999.

As of June 30, 2000, Phone.com's principal commitments consisted of obligations outstanding under operating leases and its equipment loans and capital lease obligations. On March 30, 2000, Phone.com entered into a lease for approximately 280,000 square feet of office space in Redwood City, California, that is under construction and is expected to be completed in the year 2001. Lease terms require a base rent of $3.25 per square foot per month as provided by the lease agreement and will increase by 3.5% annually on the anniversary of the initial month of the commencement of the lease. The lease term is for a period of twelve years from the commencement date of the lease. The agreement required that Phone.com provide a letter of credit in the amount of $16.5 million. As of June 30, 2000, Phone.com has guaranteed the letter of credit and has pledged approximately $20.7 million, or 125% of the letter of credit, of cash equivalents, and investments to be held in trust as security for the letter of credit. The restricted cash and investments held in trust under this agreement are earning approximately 6.7% interest and the resulting income earned is not subject to any restrictions. The lease further requires that Phone.com pay leasehold improvements, which are expected to be at least $15 million over the next year. Although Phone.com has no material other commitments for capital expenditures, it expects to increase capital expenditures and lease commitments consistent with its anticipated growth in operations, infrastructure, and personnel.

Phone.com believes that its current cash, cash equivalents, and short-term investments will be sufficient to meet its anticipated cash needs for working capital and capital expenditures for at least the next twelve months. If cash generated from operations is insufficient to satisfy its liquidity requirements, Phone.com may seek to sell additional equity or debt securities or to obtain a credit facility. If additional funds are raised through the issuance of debt securities, these securities could have rights, preferences, and privileges senior to holders of common stock, and the terms of any debt could impose restrictions on Phone.com's operations. The sale of additional equity or convertible debt securities could result in additional dilution to Phone.com's stockholders, and additional financing may not be available in amounts or on terms acceptable to Phone.com, if at all. If Phone.com is unable to obtain this additional financing, it may be required to reduce the scope of its planned product development and marketing efforts, which could harm its business, financial condition, and operating results.

Recent Accounting Pronouncements

In June 1998, the Financial Accounting Standards Board, or FASB, issued Statement of Financial Accounting Standards, or SFAS, No. 133, Accounting for Derivative Instruments and Hedging Activities, as

119

amended by SFAS No. 137. SFAS No. 133 establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts (collectively referred to as derivatives) and for hedging activities. It requires that an entity recognize all derivatives as either assets or liabilities in the statement of financial position and measure those instruments at fair value. For a derivative not designated as a hedging instrument, changes in the fair value of the derivative are recognized in earnings in the period of change. Phone.com adopted SFAS No. 133 effective July 1, 2000. Management does not believe the adoption of SFAS No. 133 will have a material effect on Phone.com's consolidated financial position or results of operations.

In December 1999, the Securities and Exchange Commission, or SEC, issued Staff Accounting Bulletin No. 101, or SAB 101, Revenue Recognition in Financial Statements, as amended by SAB 101A and SAB 101B, which provides guidance on the recognition, presentation, and disclosure of revenue in financial statements filed with the SEC. SAB 101 outlines the basic criteria that must be met to recognize revenue and provides guidance for disclosure related to revenue recognition policies. In June 2000, the SEC issued SAB 101B that delayed the implementation of SAB 101. Phone.com must adopt SAB 101 no later than the fourth quarter of fiscal 2001. The SEC has recently indicated it intends to issue further guidance with respect to the adoption of specific issues addressed by SAB 101. Until such time as this additional guidance is issued, Phone.com is unable to assess the impact, if any, it may have on its financial position or results of operations.

In March 2000, the Emerging Issues Task Force, or EITF, published their consensus on EITF Issue No. 00-2, Accounting for Web Site Development Costs, which requires that costs incurred during the development of web site applications and infrastructure, involving developing software to operate the web site, including graphics that affect the "look and feel" of the web page and all costs relating to software used to operate a web site should be accounted for under Statement of Position 98-1, Accounting for the Costs of Computer Software Developed or Obtained for Internal Use. However, if a plan exists or is being developed to market the software externally, the costs relating to the software should be accounted for pursuant to FASB Statement No. 86, Accounting for the Costs of Computer Software to Be Sold, Leased, or Otherwise Marketed. Phone.com will be required to adopt EITF Issue No. 00-2 in its first fiscal quarter, beginning after June 30, 2000. Phone.com is in the process of assessing any impact that the adoption of EITF Issue No. 00-2 will have on its consolidated financial position or results of operations.

In March 2000, the EITF published their consensus on EITF Issue No. 00-3, Application of AICPA Statement of Position 97-2, Software Revenue Recognition, to Arrangements That Include the Right to Use Software Stored on Another Entity's Hardware. EITF Issue No. 00-3 states that a software element covered by SOP 97-2 is only present in a hosting arrangement if the customer has the contractual right to take possession of the software at any time during the hosting period without significant penalty and it is feasible for the customer to either run the software on its own hardware or contract with another party unrelated to the vendor to host the software. Phone.com will be required to adopt EITF Issue No. 00-2 in its first fiscal quarter, beginning after June 30, 2000. Management does not believe the adoption of EITF Issue No. 00-3 will have a material effect on Phone.com's consolidated financial position or results of operations.

In March 2000, the FASB issued Interpretation No. 44, or FIN 44, an interpretation of Accounting Principles Board, or APB, Opinion No. 25, Accounting for Stock Issued to Employees. FIN 44 addresses inconsistencies in accounting for stock-based compensation that arise from implementation of APB Opinion No. 25. Phone.com does not anticipate that the adoption of FIN 44 will have a significant impact on Phone.com's consolidated financial position or results of operations. Phone.com adopted FIN 44 effective July 1, 2000.

Year 2000 Readiness Disclosure

With the changeover to the year 2000, Phone.com did not experience any disruption to its operations as a result of the issues associated with the limitations of the programming code in many existing computer systems, whereby the computer systems may not properly recognize or process date-sensitive information. Systems that do not properly recognize such information could generate erroneous data or cause a system to fail. There can be no assurance that there will not be future complications arising from Year 2000 issues.

Quantitative and Qualitative Disclosures About Market Risk

Foreign Currency Hedging Instruments

Phone.com transacts business in various foreign currencies and, accordingly, Phone.com is subject to exposure from adverse movements in foreign currency exchange rates. To date, the effect of changes in foreign currency exchange rates on revenues and operating expenses have not been material. Substantially all of Phone.com's revenues are earned in U.S. dollars. Operating expenses incurred by its European and Japanese subsidiaries are denominated primarily in U.K. pounds sterling and Japanese yen, respectively.

Phone.com currently does not use financial instruments to hedge operating expenses in foreign currencies. Phone.com intends to assess the need to utilize financial instruments to hedge currency exposures on an ongoing basis.

Phone.com does not use derivative financial instruments for speculative trading purposes, nor does Phone.com currently hedge its foreign currency exposure to offset the effects of changes in foreign exchange rates.

Fixed Income Investments

Phone.com's exposure to market risks for changes in interest rates relates primarily to corporate debt securities, U.S. Treasury Notes and certificates of deposit. Phone.com places its investments with high credit quality issuers and, by policy, limit the amount of the credit exposure to any one issuer.

Phone.com's general policy is to limit the risk of principal loss and ensure the safety of invested funds by limiting market and credit risk. All highly liquid investments with a maturity of less than three months at the date of purchase are considered to be cash equivalents; all investments with maturities of three months or greater are classified as available-for-sale and considered to be short-term investments. As of June 30, 2000, Phone.com's interest rate risk was further limited by the fact that all investments in our short-term investment portfolio had a maturity of less than one year.

Principal amounts of short-term investments by expected maturity:

For purposes of the change of control agreements, "involuntary termination" includes a significant reduction in the employee's duties, authority or responsibilities, a substantial reduction of facilities or perquisites, a reduction in base salary, a material reduction in employee benefits, a relocation that is more than 30 miles from the employee's then-present location, the failure of successors of Phone.com to assume the change of control agreement, the purported termination of the employee other than for disability or cause, or any act or circumstances that would constitute a constructive termination under California case law or statute.

Phone.com Employee Benefit Plans

1995 Stock Plan. Phone.com's 1995 stock plan provides for the grant of incentive stock options to employees and nonstatutory stock options and stock purchase rights to employees, directors and consultants. The purposes of the 1995 stock plan are to attract and retain the best available personnel, to provide additional incentives to Phone.com's employees and consultants and to promote the success of Phone.com's business. The 1995 stock plan was originally adopted by Phone.com's board of directors in October 1995 and approved by its stockholders in October 1995. Unless terminated earlier by the board of directors, the 1995 stock plan shall

127

terminate in October 2005. A total of 3,298,924 shares of common stock have been reserved for issuance under the 1995 stock plan. As of June 30, 2000, options to purchase 143,333 shares of common stock were outstanding at a weighted average exercise price of $0.08 per share, 3,155,591 shares had been issued upon exercise of outstanding options or pursuant to restricted stock purchase agreements, and no shares remained available for future grant.

The administrator of the 1995 stock plan may be either the board of directors or a committee of the board. The administrator determines the terms of options granted under the 1995 stock plan, including the number of shares subject to the option, exercise price, term and exercisability. Incentive stock options granted under the 1995 stock plan must have an exercise price of at least 100% of the fair market value of the common stock on the date of grant and at least 110% of the fair market value in the case of an optionee who holds more than 10% of the total voting power of all classes of our stock. Nonstatutory stock options granted under the 1995 stock plan must have an exercise price of at least 85% of the fair market value of the common stock on the date of grant (or at least 110% of the fair market value in the case of an optionee who holds more than 10% of the total voting power of all classes of our stock). Payment of the exercise price may be made in cash or other consideration as determined by the administrator.

The administrator determines the term of options, which may not exceed 10 years (or five years in the case of an option granted to a holder of more than 10% of the total power of all classes of our stock). No option may be transferred by the optionee other than by will or the laws of descent or distribution. Each option may be exercised during the lifetime of the optionee only by the optionee. The administrator determines when options become exercisable. Options granted under the 1995 stock plan generally must be exercised within 60 days after the termination of the optionee's status as an employee, director or consultant of Phone.com, or within 12 months if termination is due to the death or disability of the optionee, but in no event later than the expiration of the option's term. Options granted under the 1995 stock plan generally vest at the rate of 1/4 of the total number of shares subject to the option 12 months after the date of grant, and 1/48 of the total number of shares subject to the option each month thereafter.

In the event of Phone.com's merger with or into another corporation, each option may be assumed or an equivalent option substituted by the successor corporation. The administrator has the authority to amend or terminate the 1995 stock plan provided that no action that impairs the rights of any holder of an outstanding option may be taken without the holder's consent. In addition, stockholder approval will be obtained for any amendment to the extent required by applicable law.

In addition to stock options, the administrator may issue stock purchase rights under the 1995 stock plan to employees, directors and consultants. The administrator determines the number of shares, price, terms, conditions and restrictions related to a grant of stock purchase rights. The purchase price of a stock purchase right granted under the 1995 stock plan must be at least 85% of the fair market value of the shares as of the date of the offer. The period during which the stock purchase right is held open is determined by the administrator, but in no case shall this period exceed 30 days. Unless the administrator determined otherwise, the recipient of a stock purchase right must execute a restricted stock purchase agreement granting Phone.com an option to repurchase unvested shares at cost upon termination of the recipient's relationship with Phone.com.

1996 Stock Plan. Phone.com's 1996 stock plan provides for the grant of incentive stock options to employees and nonstatutory stock options and stock purchase rights to employees, directors and consultants. The purposes of the 1996 stock plan are to attract and retain the best available personnel, to provide additional incentives to Phone.com's employees and consultants and to promote the success of Phone.com's business. The 1996 stock plan was originally adopted by Phone.com's board of directors in September 1996 and approved by its stockholders in October 1996. The 1996 stock plan was amended by Phone.com's board of directors in March 1999 to increase the total number of shares reserved for issuance by 4,250,000 shares and to incorporate other changes. This amendment to the 1996 stock plan was approved by Phone.com's stockholders in May 1999. Unless terminated earlier by the board of directors, the 1996 stock plan shall terminate in September 2006. A total of 15,468,850 shares of common stock have been reserved for issuance under the 1996 stock plan. In

128

addition, the number of shares reserved under the plan will automatically be increased each year, beginning on July 1, 2000 in an amount equal to the lesser of (a) 3,000,000 shares, (b) four percent of the shares outstanding on the last day of the preceding fiscal year or (c) a lesser number of shares as is determined by the board of directors. As of June 30, 2000, options to purchase 11,647,120 shares of common stock were outstanding at a weighted average exercise price of $41.61 per share, 2,852,743 shares had been issued upon exercise of outstanding options or pursuant to restricted stock purchase agreements, and 968,987 shares remained available for future grant.

The administrator of the 1996 stock plan may be either the board of directors or a committee of the board. The administrator determines the terms of options granted under the 1996 stock plan, including the number of shares subject to the option, exercise price, term and exercisability. In no event, however, may an individual receive option grants for more than 2,000,000 shares under the 1996 plan in any fiscal year. Incentive stock options granted under the 1996 stock plan must have an exercise price of at least 100% of the fair market value of the common stock on the date of grant and at least 110% of the fair market value in the case of an optionee who holds more than 10% of the total voting power of all classes of Phone.com's stock. Nonstatutory stock options granted under the 1996 stock plan must have an exercise price of at least 85% of the fair market value of the common stock on the date of grant. Payment of the exercise price may be made in cash or other consideration as determined by the administrator.

The administrator determines the term of options, which may not exceed 10 years (or five years in the case of an option granted to a holder of more than 10% of the total voting power of all classes of our stock). No option may be transferred by the optionee other than by will or the laws of descent or distribution provided, however, that the administrator may in its discretion provide for the transferability of nonstatutory stock options granted under the 1996 stock plan. Each option may be exercised during the lifetime of the optionee only by the optionee or permitted transferee. The administrator determines when options become exercisable. Options granted under the 1996 stock plan generally must be exercised within 30 to 90 days, as determined by the administrator, after the termination of the optionee's status as an employee, director or consultant of Phone.com, or within 12 months if termination is due to the death or disability of the optionee, but in no event later than the expiration of the option's term. Options granted under the 1996 stock plan generally vest over a period of four or five years.

In the event of Phone.com's merger with or into another corporation, each option may be assumed or an equivalent option substituted by the successor corporation. However, if the successor corporation does not agree to assume or substitute the option, the option will terminate. The administrator has the authority to amend or terminate the 1996 stock plan provided that no action that impairs the rights of any holder of an outstanding option may be taken without the holder's consent.

In addition, stockholder approval is required to increase the number of shares subject to the 1996 stock plan, to change the designation of the class of persons eligible to be granted options or to increase the individual grant limitation. In addition to stock options, the administrator may issue stock purchase rights under the 1996 stock plan to employees, directors and consultants. The administrator determines the number of shares, price, terms, conditions and restrictions related to a grant of stock purchase rights. The purchase price of a stock purchase right granted under the 1996 stock plan must be at least 85% of the fair market value of the shares as of the date of the offer. The period during which the stock purchase right is held open is determined by the administrator, but in no case shall this period exceed 30 days. Unless the administrator determines otherwise, the recipient of a stock purchase right must execute a restricted stock purchase agreement granting Phone.com an option to repurchase the unvested shares at cost upon termination of the recipient's relationship with Phone.com.

2000 Non-Executive Stock Option Plan (2000 stock plan). Phone.com's 2000 stock plan provides for the grant of non-statutory stock options to employees and consultants. The purposes of the 2000 stock plan are to attract and retain the best available personnel, to provide additional incentives to Phone.com's employees and consultants and to promote the success of Phone.com's business. The 2000 stock plan was originally adopted by

129

Phone.com's board of directors on May 3, 2000. Unless terminated earlier by the board of directors, the 2000 stock plan shall terminate on May 3, 2010. A total of 2,000,000 shares of common stock have been reserved for issuance under the 2000 stock plan. As of June 30, 2000, options to purchase 1,246,777 shares of common stock were outstanding at a weighted average exercise price of $75.31 per share, no shares had been issued upon exercise of outstanding options, and 753,223 shares remained available for future grant.

The administrator of the 2000 stock plan may be either the board of directors or a committee of the board. The administrator determines the terms of options granted under the 2000 stock plan, including the number of shares subject to the option, exercise price, term and exercisability. In no event, however, may an individual receive option grants for more than 2,000,000 shares under the 2000 plan in any fiscal year. Nonstatutory stock options granted under the 2000 stock plan must have an exercise price of at least 85% of the fair market value of the common stock on the date of grant. Payment of the exercise price may be made in cash or other consideration as determined by the administrator.

The administrator determines the term of options, which may not exceed 10 years. No option may be transferred by the optionee other than by will or the laws of descent or distribution provided, however, that the administrator may in its discretion provide for the transferability of nonstatutory stock options granted under the 2000 stock plan. Each option may be exercised during the lifetime of the optionee only by the optionee or permitted transferee. The administrator determines when options become exercisable. Options granted under the 2000 stock plan generally must be exercised within 30 to 90 days, as determined by the administrator, after the termination of the optionee's status as an employee or consultant of Phone.com, or within 12 months if termination is due to the death or disability of the optionee, but in no event later than the expiration of the option's term. Options granted under the 2000 stock plan generally vest over a period of four or five years.

In the event of Phone.com's merger with or into another corporation, each option may be assumed or an equivalent option substituted by the successor corporation. However, if the successor corporation does not agree to assume or substitute the option, the option will terminate. The administrator has the authority to amend or terminate the 2000 stock plan provided that no action that impairs the rights of any holder of an outstanding option may be taken without the holder's consent.

1999 Employee Stock Purchase Plan. Phone.com's employee stock purchase plan was adopted by the board of directors in March 1999 and was approved by Phone.com's stockholders in May 1999. A total of 1,200,000 shares of common stock has been reserved for issuance under the employee stock purchase plan, plus an automatic annual increase on the first day of each of our fiscal years beginning in 2000, 2001, 2002, 2003 and 2004 equal to the lesser of 1,000,000 shares or 1% of Phone.com's outstanding common stock on the last day of the immediately preceding fiscal year. Unless terminated earlier by the board of directors, the employee stock purchase plan shall terminate in March 2019.

The employee stock purchase plan, which is intended to qualify under Section 423 of the Code, will be implemented by a series of overlapping offering periods of approximately 24 months' duration, with new offering periods (other than the first offering period) commencing on May 1 and November 1 of each year. Each offering period will generally consist of four consecutive purchase periods of six months' duration, at the end of which an automatic purchase will be made for participants. The initial offering period commenced on June 11, 1999
and will end on April 30, 2001; the initial purchase period began on June 11, 1999 and ended on January 31, 2000, with subsequent purchase periods ending on April 30, 2000, October 31, 2000 and April 30, 2001. The employee stock purchase plan will be administered by the board of directors or by a committee appointed by the board. Phone.com's employees (including officers and employee directors), or of any majority-owned subsidiary designated by the board, are eligible to participate in the employee stock purchase plan if they are employed by Phone.com or a subsidiary of Phone.com for at least 20 hours per week and more than five months per year. The employee stock purchase plan permits eligible employees to purchase common stock through payroll deductions, which in any event may not exceed 20% of an employee's base salary. The purchase price is equal to the lower of 85% of the fair market value of the common stock at the beginning of each offering period or at the end of

130

each purchase period. Employees may end their participation in the employee stock purchase plan at any time during an offering period, and participation ends automatically on termination of employment.

An employee cannot be granted an option under the employee stock purchase plan if immediately after the grant the employee would own stock and/or hold outstanding options to purchase stock equaling 5% or more of the total voting power or value of all classes of Phone.com's stock or stock of Phone.com's subsidiaries, or if the option would permit an employee to purchase stock under the employee stock purchase plan at a rate that exceeds $25,000 of fair market value of stock for each calendar year in which the option is outstanding. In addition, no employee may purchase more than 5,000 shares of common stock under the employee stock purchase plan in any one purchase period. If the fair market value of the common stock on a purchase date is less than the fair market value at the beginning of the offering period, each participant in that offering period shall automatically be withdrawn from the offering period as of the end of the purchase date and re-enrolled in the new twenty-four month offering period beginning on the first business day following the purchase date.

If Phone.com merges or consolidates with or into another corporation or sells all or substantially all of its assets, each right to purchase stock under the employee stock purchase plan will be assumed or an equivalent right substituted by the successor corporation. However, the board of directors will shorten any ongoing offering period so that employees' rights to purchase stock under the employee stock purchase plan are exercised prior to the transaction in the event that the successor corporation refuses to assume each purchase right or to substitute an equivalent right of the acquiring corporation. The board of directors has the power to amend or terminate the employee stock purchase plan and to change or terminate offering periods as long as this action does not adversely affect any outstanding rights to purchase stock thereunder. However, the board of directors may amend or terminate the employee stock purchase plan or an offering period even if it would adversely affect outstanding options in order to avoid our incurring adverse accounting charges.

Phone.com Limitation of Liability and Indemnification

Phone.com's certificate of incorporation limits the liability of directors to the maximum extent permitted by Delaware law. Delaware law provides that a director of a corporation will not be personally liable for monetary damages for breach of an individual's fiduciary duties as a director except for liability;

. for any breach of a director's duty of loyalty to Phone.com or to its stockholders;

. for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law;

. for unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the Delaware General Corporation Law; or

. for any transaction from which a director derives an improper personal benefit.

Phone.com's bylaws provide that Phone.com shall indemnify its directors and executive officers and may indemnify its officers, employees and other agents to the full extent permitted by law. Phone.com believes that indemnification under its bylaws covers at least negligence and gross negligence on the part of an indemnified party. Phone.com's bylaws also permit it to advance expenses incurred by an indemnified party in connection with the defense of any action or proceeding arising out of a party's status or service as a director, officer, employee or other agent of Phone.com upon an undertaking by the party to repay the advances if it is ultimately determined that he or she is not entitled to indemnification.

Phone.com has entered into separate indemnification agreements with each of our directors and officers. These agreements require Phone.com to, among other things, indemnify the director or officer against expenses (including attorney's fees), judgments, fines and settlements paid by the individual in connection with any action, suit or proceeding arising out of the individual's status or service as a director or officer of Phone.com (other than liabilities arising from willful misconduct or conduct that is knowingly fraudulent or deliberately dishonest)

131

and to advance expenses incurred by the individual in connection with any proceeding against the individual with respect to which he or she may be entitled to indemnification by Phone.com. Phone.com believes that its certificate of incorporation and bylaw provisions and indemnification agreements are necessary to attract and retain qualified persons as directors and officers. Phone.com also maintains directors' and officers' liability insurance.

At present, Phone.com is not aware of any pending litigation or proceeding involving any director, officer, employee or agent of Phone.com where indemnification will be required or permitted. Furthermore, Phone.com is not aware of any threatened litigation or proceeding that might result in a claim for indemnification.

SOFTWARE.COM BUSINESS

Overview

Software.com develops and markets Internet infrastructure software based on open standards and protocols for Internet and telecommunications service providers. It designs this software, which it refers to as Internet infrastructure software, to enable communications service providers to transition to the Internet as the technology foundation for worldwide communications and services. Software.com's infrastructure software platform and related applications are designed exclusively for the communications service provider market: traditional telecommunications carriers; Internet service providers (or ISPs) and wholesalers; cable-based, Internet access providers; application service providers (or ASPs); competitive local exchange carriers; Internet destination sites or portals; and wireless telephony carriers. Software.com believes that a fundamental component of the success and timing of the transition to an Internet-based communications structure will be enabling and empowering those service providers who possess the vision, experience, infrastructure and economies of scale to bring next- generation communications and services to the consumer and business mass- markets. There is significant and increasing competition for users of these new services, especially with the expansion of the wireless market. Therefore, Software.com believes successful service providers must utilize Internet infrastructure platforms and applications that have the ability to perform at increasingly high capacities, or scale, and that have the flexibility to unite both traditional and next-generation communication devices within a common architecture in a cost-effective manner.

Software.com's business is focused on equipping communications service providers with a highly scalable and extensible infrastructure software platform based on open standards that enables them to offer the most competitive, next generation communication services to millions of subscribers. To accomplish this, it provides its customers with a scalable and extensible software platform and selected applications leveraging the underlying components of this platform, as well as a broad range of consulting and customer support services that complement these offerings. Since Software.com's founding in 1993, its vision has remained the same-supplying standards-based, service provider software solutions enabling Internet and communications services.

In the race to build user bases, service providers increasingly focus on providing applications and services that help attract and retain customers. Software.com's initial applications, based on the underlying infrastructure software platform have been designed to provide service providers with a common platform for multiple electronic messaging services. Internet electronic mail, or Internet email, has proven to be one of the most popular applications on the Internet and a compelling application for attracting subscribers. The growth in the use of Internet email has also attracted businesses, as email becomes a routine method of communicating among employees and with customers, vendors, and partners. As service providers seek to differentiate offerings to attract more business users, service providers are expanding basic email service to create new and innovative Internet-based messaging services, including "fail-safe" email, wireless messaging, and new types of unified communications services such as integrated email, faxmail and voicemail.

To take advantage of opportunities in both consumer and business messaging, service providers must deploy messaging services capable of meeting the evolving needs of these groups. Service outages or the loss of messages can lead to adverse publicity for service providers, and can result in the loss of substantial numbers of subscribers. In order to leverage infrastructure investments, service providers must provide systems that can grow to accommodate hundreds of thousands, or even millions, of users and the rapidly increasing number of messages being sent by their larger user bases. Most service providers, however, have neither the products and services in place nor the existing internal technical and development capabilities to address this enormous growth.

Software.com's service provider customers deploy its scalable, high- performance infrastructure software platform and related applications to deliver advanced messaging services to their consumer and business subscribers. Its products have been proven to deliver messaging services in some of the most demanding service provider environments in the world, including those of AT&T WorldNet(R) Service, Excite@Home, Japan Telecom, Sprint PCS, Telecom Italia Net, Telecom Italia Mobile and Verizon. As of June 30, 2000, Software.com

136

had licensed approximately 116 million seats and estimates that approximately 70 million of these seats had been activated. It combines its infrastructure software platform, applications and services to create advanced solutions that provide several benefits to communications service providers.

Software.com's infrastructure software is designed to easily scale and enable a service provider to offer an increasing array of applications and services to a rapidly-growing number of subscribers. Software.com designs its products to be highly available, meaning that a user can access the service when needed, as well as highly reliable, meaning that the users do not lose data that is sent or received. In addition, its technology enables service providers to create, manage, and host multiple offerings on the same infrastructure software platform. A service provider can therefore easily tailor feature sets to meet the different and evolving needs of individual segments of its subscriber base. In addition to its infrastructure software, Software.com offers business planning, system design, capacity planning, on- site operations training, and integrated support services to help service providers rapidly pilot, launch and scale innovative new service offerings. After completion of a consulting engagement, Software.com's professional services staff passes essential, site-specific knowledge to its support staff to facilitate a smooth transition from deployment to ongoing customer care. It supports its customers' sites on a 24 hour basis and has developed sophisticated tracking and response systems to provide customers with the highest quality support.

Software.com's goal is to be the leading provider of Internet infrastructure software designed for communications service providers. To this end, it intends to continue its exclusive focus on the communications service provider market. Software.com believes that its exclusive focus on service providers, as opposed to the enterprise market, enables it to better identify and offer the feature sets and attributes that are required for its products to be successful in the communications service provider marketplace. Within the communications service provider marketplace, it focuses its sales efforts on the world's largest service providers. Software.com believes that this strategy allows it to capture the broadest possible user base while targeting a limited number of accounts. It also believes that winning the large, well- known accounts helps its sales to smaller and medium sized providers by enhancing its reputation as a leading provider of Internet infrastructure software in the communications service provider market. Software.com also intends to leverage its infrastructure software platform to build additional service provider applications. For example, Software.com has integrated web- based technology, acquired in the Mobility.Net acquisition of April 1999, to enhance the performance of its existing Web interface and ultimately extend the reach of its infrastructure software platform to encompass additional Web- based applications. Software.com has pursued a similar strategy to leverage the wireless technologies acquired in the Telarc acquisition of October 1999. In April 2000 Software.com acquired AtMobile.com, Inc., (or AtMobile), a wireless Internet application developer with Instant Messaging technology and Wireless Intelligent Network integration expertise. Software.com is working on integrating the AtMobile wireless applications to leverage the infrastructure software platform and increase the scope of service offerings for communications service providers. Software.com intends to add more applications as extensions to the infrastructure software platform through internal development, external development programs, partnering arrangements or the acquisition of third party technologies. Software.com also intends to continue to leverage the expertise of its professional services organization to help customers design, build, and deploy systems based on its products.

Post.Office

Designed to meet the messaging needs of small to medium size service providers, Post.Office is typically chosen by service providers with 100 to 25,000 users, although it can scale to support up to 250,000 subscribers on a single UNIX server. E-mail system administrators, or postmasters, can use Post.Office to easily administer their entire email systems, while allowing end users to manage their individual email accounts. Post.Office provides a user-friendly administration interface featuring fill-in-the-blank forms and pop-up options assisted by Web-based help links. Post.Office offers a broad array of security features, including multiple password protection levels and numerous user restriction settings. Post.Office also provides a variety of features for preventing the sending and receiving of Internet junk mail, or "spam." Post.Office operates independently of the host computer system, making it difficult to compromise the main system security through the email application.

InterMail Kx and InterMail Mx

The InterMail Mx and InterMail Kx product packages are designed to meet the rapidly evolving needs of communications service providers and provide the foundation for continued growth in applications and service offerings. InterMail Kx and InterMail Mx are designed to enable service providers to offer premium consumer, business, and Web-based messaging services from a single, integrated solution. InterMail Kx is designed for fast-growing, medium-sized service providers with a subscriber base of up to 400,000. InterMail Mx, which is designed for the largest service providers, scales to support millions of subscribers. The InterMail Kx and InterMail Mx product packages provide postmasters with a suite of powerful system administration tools that enable streamlined subscriber account creation and management. InterMail Kx and InterMail Mx components run on multiple servers, providing greater scalability, reliability, and performance than a single server system.

Within the InterMail Kx and InterMail Mx product packages, Software.com has developed a broad set of customizable messaging applications, which are designated as different editions: InterMail Standard Edition, InterMail Business Advantage Edition and the recently developed, initial version of InterMail IP Unified Messaging (IPUM) Edition. InterMail Mx also offers the InterMail Mx Mobile Mail Edition, specifically designed for mobile messaging users. These editions provide a range of functionality and allow service providers to create and customize multiple classes of service at varying price points for consumer and business subscribers. A single InterMail Kx or InterMail Mx installation can host multiple classes of messaging services, thereby eliminating the expense associated with running separate systems. These capabilities help service providers to expand market share, retain subscribers, lower total cost of ownership, and derive increased profits from their businesses. Additionally, Software.com recently began selling a highly scalable, Lightweight Directory Access Protocol

138

(LDAP) Directory, as part of InterMail Mx, and upon which its service provider customers can design and develop multiple directory applications.

InterMail Standard Edition-Designed for service providers offering consumer email or hosting the consumer-oriented services of another service provider, InterMail Standard Edition provides a standard post office protocol or POP3 mailbox, and interfaces with commonly used desktop email clients such as Microsoft Outlook and Outlook Express, Netscape Navigator, and QUALCOMM Eudora. InterMail Standard Edition also includes the ability to access mailboxes from any location where the Internet can be accessed through commonly used Internet browsers such as Microsoft Internet Explorer and Netscape Navigator. InterMail Standard Edition is typically bundled with dial- up or cable access as part of an entry level service provider offering. As with all its InterMail editions, InterMail Standard Edition supports individual account spam protection.

InterMail Business Advantage Edition-Designed for service providers offering managed messaging to businesses or hosting the business-oriented services of another service provider, InterMail Business Advantage Edition enables service providers to offer fully-functional business mailboxes. InterMail Business Advantage Edition provides a full range of advanced features, including the advanced Internet protocol for delivery and retrieval of messages known as IMAP4, enhanced message encryption, delegated administration, and customer self-care tools.

InterMail IP Unified Messaging Edition-InterMail IP UM Edition is designed to provide a full function "universal mailbox" that works with Internet standards-based voicemail and faxmail network components. Software.com's solution is intended to be a cost-efficient replacement for traditional call answering, or as a more functional universal mailbox where email, faxmail and voicemail messages are stored in a single mailbox accessed either by telephone or computer.

Wireless

Software.com has developed InterMail Mx Mobile Mail Edition and will continue to develop additional wireless applications, based on its infrastructure software platform, to enable service providers to meet the increasing demands of both consumer and business customers to expand mobile communications and access to Internet content and services beyond wireline devices. For example, it has developed products designed to enable the extraction and encoding of Internet data (typically found in HyperText Markup Language (HTML), the document format language used on the World Wide Web) into a document format language, such as Wireless Markup Language (WML) or compact HTML (cHTML), that is readable on particular wireless devices.

Professional and Support Services

Software.com has designed its professional services offerings to enable its customers to bring their service offerings to market more quickly by leveraging its significant expertise in deploying and managing large-scale messaging solutions. Software.com's professional services offerings include a wide range of consulting services such as business planning services, system assessment, system architecture review, system migration, and operations management, as well as rapid deployment and integration of its InterMail messaging products. It offers professional services in connection with the initial deployment of its products, as well as on an ongoing basis to address the continuing needs of its customers.

. Competitive Local Exchange Carriers (CLECs): This group is made up of companies, other than RBOCs, that offer local phone service. These companies typically also offer Internet connectivity and services.

. Internet Portals: A number of companies position themselves as Internet destination sites, or portals, a point of entry to the Internet for a consumer or business. Many of these portals offer messaging services to consumers without charge, generating revenues instead by selling advertising space on the message screens.

. Wireless Telephony Carriers: This group is made up of companies that offer wireless network services (such as telephone and short messaging services) and, increasingly, Internet access and services (such as content delivery to mobile devices).

Strategic Relationships

Software.com has established a number of formal and informal relationships with companies that provide Internet infrastructure components and software to service providers. It works with these companies to expand sales channels and to develop additional applications and services based on Software.com's infrastructure platform. Set forth below are descriptions of its relationships with several of its partners:

Cisco Systems. Software.com has been working with Cisco Systems on a variety of product development efforts, including unified communications based on Internet protocols, network (hosted) applications, and

140

directory technology. Its work with Cisco has focused on providing solutions for common customers and partners. In February 1997, Cisco made the first of two equity investments in Software.com.

Hewlett-Packard. Hewlett-Packard has selected InterMail as its preferred messaging application for the service provider market. Hewlett-Packard markets solutions, including its applications, to rapidly growing service providers that are building the infrastructure to offer unified communications and managed messaging services and to those offering Internet services to consumers and businesses. Software.com also works closely with Hewlett-Packard to improve the performance and customization of its applications on Hewlett- Packard's HP-UX operating systems. In April 1999, Hewlett-Packard purchased a minority equity interest in Software.com.

IBM. IBM offers InterMail Kx and Post.Office on its high performance operating systems and hardware, including bundled offerings of InterMail Kx and Post.Office on its servers. Software.com's works with IBM on a high availability, high reliability, carrier-scale performance solution based on InterMail and IBM's Serial Storage Architecture disk subsystems, and high- availability cluster multiprocessing software. In addition, IBM integrates its Intelligent Subscriber Management System with InterMail for IBM's service provider customers.

Telcordia Technologies. Software.com's Strategic Solutions and Professional Services groups have been working with Telcordia Technologies (formerly Bellcore) on deploying a next-generation, unified messaging platform based on standard Internet protocols. It will continue to partner with Telcordia to explore emerging opportunities created by the convergence of voice and data networks, including voicemail and faxmail based on Internet protocols.

Nortel. Nortel Networks has selected the InterMail platform as a messaging component of its Managed Application Services Initiative, giving application service providers (ASPs) an end-to-end solution. It will continue to partner with Nortel to explore emerging opportunities created by the convergence of voice and data networks, including voicemail and faxmail based on Internet protocols in the ASP market.

Software.com works closely with many other UNIX vendors to customize its messaging software to run on their systems. These relationships enable Software.com to sell its products to service providers that use different hardware platforms. It has relationships with Sun Microsystems (for Solaris) and Compaq/DEC (for Digital UNIX). It also works on integration, sales and marketing projects with other companies that currently sell in the service provider market, including several billing/provisioning systems vendors.

Sales

Software.com markets and sells its Internet infrastructure software and services exclusively to communications service providers. Its sales strategy focuses on the pursuit of key accounts worldwide through a direct sales force and additional market segments through a combination of direct and indirect channels. It divides the communications service provider market into three segments: Tier One, Tier Two, and Tier Three. Software.com's sales approach for a given customer depends upon the tier in which it categorizes the customer's account.

Tier One Accounts

Tier One accounts consist of a designated list of the largest and most well- known communications service providers in the world, and are targeted by its direct sales force. Software.com's InterMail Mx product is specifically designed for these Tier One accounts whose current subscriber base generally exceeds 250,000 users, and whose projected subscriber base generally exceeds one million users. Software.com has Tier One direct sales force personnel located in California, Washington, Colorado, Texas, Virginia, Massachusetts, England, Germany, France, Italy, Spain, the Netherlands, Sweden, Japan, Korea, Australia, and the People's Republic of China (PRC). The direct sales force is organized into account teams, consisting of a sales director and a sales engineer, or "technology consultant," and shared account managers. Each team has responsibility for a designated number of Tier One accounts in the region. Software.com generate sales leads for Tier One accounts through a

141

combination of direct and indirect initiatives, such as conferences, presentations and responses to requests for proposals. The Tier One sales process typically involves a large expense commitment from Software.com and the sales cycle in these accounts lasts from several months to over a year. Software.com intends to increase the size of its direct sales force in the Americas, Europe, and Asia to further pursue Tier One account opportunities. In addition, Software.com intends to engage more strategic partners to increase its indirect channels for Tier One accounts.

Tier Two Accounts

Software.com characterizes Tier Two accounts as those service providers with a current subscriber base in excess of 25,000 users and a projected subscriber base of up to 400,000 users. The performance and feature requirements of Tier Two accounts are closely aligned with those of larger service providers. Software.com offers the InterMail Kx package to satisfy the requirements for these Tier Two accounts. It targets these accounts through a combination of direct and indirect channels, referred to as the "territory" channel. Software.com has Tier Two direct sales force personnel located in California, Colorado, Massachusetts, Texas, Florida, Virginia, Italy, Japan, PRC, Singapore, and the Netherlands. The Tier Two direct sales force is complemented by multiple indirect distribution channel partners, including resellers, systems integrators, and joint marketing partners, such as IBM, Nortel and Hewlett-Packard. The majority of its indirect sales partners purchase software from Software.com at a specified discount and resell the software to their customers. The indirect channels are designed to increase geographic sales coverage for Tier Two service providers and to leverage the existing sales organizations of key strategic partners. Software.com is in the early stages of building these distribution channels and intends to significantly increase its indirect channel for territory sales.

Tier Three Accounts

Tier Three accounts consist of small to medium size service providers that operate on a single-server architecture and typically have an installed base of less than 25,000 users. In general, these small to medium size service providers are best suited for the Post.Office product package. Software.com targets these accounts primarily through indirect channels, including resellers, systems integrators, and joint marketing partners. However, Software.com also has several Tier Three direct telephone sales force personnel located in California. It conducts a substantial amount of Tier Three sales via its external website with direct software downloads to users.

Marketing

Software.com engages in a broad range of marketing activities, including advertising its products and services in print and electronic media, sponsoring seminars and events for customers and potential customers, participating in trade shows and conferences, and providing product information through its Web site. It also works closely with the marketing departments of its strategic partners and customers to promote new service offerings, including their messaging initiatives, that are enabled by its products. These efforts are augmented with the assistance of several public relations firms specializing in the technology marketplace in an effort to further establish and define the market for highly scalable infrastructure software for communications service providers. For the Tier Two and Tier Three market segments, Software.com periodically undertakes direct mail programs designed to promote brand name awareness and inform existing customers of advances in product features. In addition, it periodically publishes white papers and industry reports to promote awareness of its technology and advances in industry practices.

Technology

Infrastructure Software Platform

Software.com has developed a scalable, high performance infrastructure software platform upon which its service provider customers can build Internet standards-based applications and services, such as messaging. This infrastructure software platform consists of a number of core technologies and/or components. Software.com's

142

software "partitions" or separates application processing into a series of steps, such as retrieving a message from the Internet, storing it on disk, and delivering it to the user. The software for each step is called a component, and a set of partitioned components makes up a cluster. The components and the clustering concept are described below.

Replicated, Multi-Master Directory. The central component of Software.com's software infrastructure platform is the directory repository, which stores information about each user of the application. Each component in a distributed platform needs to access common information, such as a user's name and password. This data is accessed every time an application interacts with a user or with another application in a cooperative processing environment. As a result, specialized, replicated directory technology is needed to support a large cluster. Software.com's directory has a core database that contains the common information and a set of high-speed multi-threaded partitioned replicas of that information, meaning that different operations can take place concurrently within the same program. By using multiple replicas, the common information can be accessed a virtually unlimited number of times. The replicas support the industry standard Lightweight Directory Access Protocol (LDAP) access, so third party applications can access information in a standard format. The directory is a "multi-master" system, meaning that applications can access or add information to any replica and the directory will automatically update the database and other replicas so that data is consistent across all components. These advanced replication and updating protocols are unique to the directory system and are a key element in providing scalability. Numerous enhancements, such as partial replication, transaction support and batch processing make the Software.com directory an infrastructure component and a centrally provisioned entity in the system.

Multimedia Object Store. The object-level storage component is used to reliably and efficiently store, organize and retrieve a variety of data types, including text, graphics, voice, audio, video, and facsimile. In Software.com's storage component, data is accessed via an object-oriented software layer, which uses self-contained, reusable pieces of software code known as "objects" to separate, protect, and isolate the data from the components that use it, so that both the data structures and components can be independently updated. Software.com's object store is multithreaded, meaning that several specific tasks within the component are run in parallel. It utilizes a high degree of caching, where frequently used information is kept in memory, to increase performance and scalability for data intensive operations. The object store has an extensible file system layout, so that additional storage can be added while the system is on-line, supporting high availability operation.

Partitioned Cluster Architecture. The Software.com architecture consists of software components arranged as a loosely coupled cluster. All components can run on a single computer for a smaller system, or can be distributed across many computers for a large system. When required, components can be duplicated to provide even more capacity. The partitioned cluster architecture increases performance and capacity by doing steps in parallel on separate computers. Disk intensive operations, such as saving messages on the disk, are separated from network intensive operations, such as delivering messages to the Internet. The computer running a disk-intensive component can be optimized for high-speed disk access, while the network intensive component can run on a much less expensive computer. Partitioning increases overall performance and capacity while minimizing hardware costs. Components are location independent in that they can be freely moved from one computer to another to reconfigure the cluster. Hardware can be added or removed from the cluster while it continues to operate. Duplicating individual partitions enables high- availability or non-stop operation, where the cluster continues to run even with a particular partition out of service.

Distributed Object Protocol. Software.com has developed an innovative distributed object communications protocol for reliable, efficient communications between the components. This protocol, called Remote Method Execution, or RME, supports messaging transactions and journaling to ensure that the cluster is reliable. A transaction is composed of several operations, such as inserting a message into a user's mailbox. Software.com's transaction software ensures that every operation is either fully completed or fully reversed so it can be done at a later time. A list of completed transactions is kept in a separate file, called a journal. The journal is used to reconstruct the messages in the event that there is a system failure. In addition, RME has a

143

"versioning" mechanism that allows older components to properly work with newer ones. This allows upgrading the cluster to new software while the cluster is running for non-stop operation. RME provides a high performance programming interface to all components and enables Software.com and third parties to create new messaging applications.

Access and Delivery Components. Software.com's cluster has a set of data access and delivery servers that implement industry standard protocols, such as those used in messaging. The Message Transport Agent (MTA) implements simple mail transfer protocol or SMTP, the standard protocol used to send mail from one computer to another on the Internet. POP3 and IMAP4 data access components implement the protocols used by desktop email applications, such as Microsoft Outlook or Netscape Navigator. The Web component provides a complete Web server for accessing email using standard browsers. Software.com's Mobility.Net technology provides additional flexibility for service providers to customize their Web interfaces. The number and type of access components can be optimized to meet the requirements of particular service providers.

Applications and Related Technologies.

Unified Messaging. Software.com's software infrastructure platform has been integrated with voice-over Internet protocol, or VOIP, gateway services from vendors such as Cisco Systems. In a typical unified communications system, voice and fax data are converted into email messages, which are then delivered to the message storage system for storage and retrieval. An LDAP directory provides account and mailbox information storage. Software.com's unified messaging platform also provides service providers the ability to leverage their existing subscriber bases and offer enhanced services such as unified mailbox and integrated fax services. In addition to offering a unified communications platform for new market entrants, Software.com's software infrastructure platform may also allow a service provider to replace legacy voice mail servers, thereby reducing costs, increasing telephony bandwidth and maintaining a flexible service creation platform.

Telephony Integration. Software.com's Telarc technology provides an infrastructure for the convergence of IP network services and telephony network services by enabling IP-based access directly to networks using standard telephony protocols known as Signaling System 7 (SS7) protocols. The SS7 protocols form an important infrastructure component for the delivery of voice and information over the various wireless networks. Software.com's Telarc technology also allows it to offer products to service providers in the short messaging services market by allowing direct access to the mobile switching centers of a wireless telephony provider.

Software.com is working to layer applications developed from the AtMobile technology upon the Telarc infrastructure. It plans to leverage AtMobile's Wireless Intelligent Networking expertise and its Instant Messaging technology with the LDAP directory to address the wireless data services needs of wireless network carriers, to produce a wireless Instant Messaging product, and ultimately to enhance its software infrastructure platform and short messaging technology. Software.com's goal is to enable its customers to provide end-to-end wireless unified communications solutions to their subscribers.

Mobility.Net Technology. Software.com's Mobility.Net technology consists primarily of software designed to improve a user's ability to retrieve and send electronic messages using a Web browser. This is referred to as a Web access server. It has integrated the Mobility.Net technology into its Post.Office and InterMail product packages to improve the performance of its Web access server and to enable Software.com to offer additional features that are dependent on advanced Web access server technology.

Software.com has made substantial investments in research and development. It believes that its future performance will depend in large part on its ability to maintain and enhance its current platform and product families, develop or acquire new products that achieve market acceptance, maintain technological competitiveness and meet an expanding range of service provider requirements. As of June 30, 2000, Software.com's research and development staff consisted of 170 employees.

144

Competition

The market for Internet infrastructure software products and services is intensely competitive, and Software.com expects it to become increasingly so in the future. Software.com competes in its core service provider market with many software providers and, in some instances, with outsourced messaging providers who have either internally developed or acquired their own messaging software. It also competes, principally on the basis of performance, features and price, against messaging solutions based on public domain software code that is developed and enhanced internally by service providers. Software.com competes to a more limited extent with providers of messaging applications designed for the enterprise market.

Software.com's current software competitors in the service provider market include iPlanet E-Commerce Solutions (a SunNetscape Alliance) and Isocor, which was recently acquired by Critical Path. It also indirectly competes with Critical Path when it offers outsourced messaging to the service provider market and with Microsoft, whose current messaging product was developed for the enterprise market but is sold to some service providers. In addition, with Software.com's release of a highly scalable LDAP directory with InterMail Mx, it will more directly compete with Novell's NDS technology and Microsoft's Active Directory product, to the extent that these products are marketed to service providers. In addition, as it continues to enter the wireless messaging market, a rapidly developing field, several larger companies could turn out to be its competitors. Software.com believes that competition will intensify as its current competitors increase the sophistication of their offerings and as new market participants, including additional providers of outsourced messaging services enter the market. Many of its current and future competitors have longer operating histories, larger installed customer bases, greater brand recognition, and significantly greater financial, marketing and other resources than it does. In addition, these competitors may benefit from existing strategic and other relationships with each other or with Software.com's current customers. Software.com must respond quickly and effectively to the new products, services, and enhancements offered by its competitors in order to continue its growth.

Microsoft, among other software providers, is well-positioned to become increasingly competitive in Software.com's core service provider messaging market. Software.com believes that Microsoft is currently in the process of developing electronic messaging software to compete more directly in its core service provider market. Because of its dominance in other software markets, Microsoft has many competitive advantages over Software.com. For example, Microsoft could incorporate electronic messaging technology into its Web browser software, its client operating system or email interface, or its server software offerings, possibly at no additional cost to service providers or end users. In addition, Microsoft may promote technologies and standards that are not compatible with Software.com's technology, or that are less compatible with Software.com's technology than competitive products offered by Microsoft. Software.com believes that Microsoft's increasing presence in the electronic messaging software industry will dramatically increase competitive pressure in the market, leading to increased pricing pressure and longer sales cycles. These competitive pressures may force Software.com to reduce the prices of its products, and may also materially reduce its market share.

In addition to the existing competitors listed above, voicemail solutions providers could be formidable competitors in the unified communications infrastructure software and Internet voicemail markets because of their established presences as voicemail providers to the service provider market and ownership of technologies for the conversion of voice to data. If it is unable to cooperate or compete effectively with Microsoft, existing voicemail solution providers, or its other existing or emerging competitors, Software.com's business, financial condition, and operating results will suffer.

Intellectual Property and Proprietary Rights

Software.com's ability to compete and continue to provide technological innovation is substantially dependent upon internally developed technology, including the entire InterMail product line. It relies on a combination of copyright, trade secret, patent and trademark law to protect its technology, although it believes that other factors such as the technological and creative skills of its personnel, new product developments, frequent product and feature enhancements, and reliable product support and maintenance are more essential to

maintaining a technology leadership position. As of June 30, 2000, Software.com had one patent issued and a number of patent applications, primarily for wireless subject matter.

Software.com generally enters into confidentiality and nondisclosure agreements with its employees, consultants, prospective customers, licensees, and corporate partners. In addition, it controls access to and distribution of its software, documentation, and other proprietary information. Except for certain limited escrow arrangements, it does not provide third parties with access to the source code for its products. Despite Software.com's efforts to protect its intellectual property and proprietary rights, unauthorized parties may attempt to copy or otherwise obtain and use its products or technology. Effectively policing the unauthorized use of its products is time-consuming and costly, and there can be no assurance that the steps taken by Software.com will prevent misappropriation of its technology, particularly in foreign countries where in many instances the local laws or legal systems do not offer the same level of protection as in the United States.

Software.com attempts to avoid infringing known proprietary rights of third parties in its product development efforts. However, it does not regularly conduct comprehensive patent searches to determine whether the technology used in its products infringes patents held by third parties. There are many issued patents as well as patent applications in the Internet infrastructure software and electronic messaging fields. Because patent applications in the United States are not publicly disclosed until the patent is issued, applications may have been filed which relate to its software products. In addition, Software.com's competitors and other companies as well as research and academic institutions have conducted research for many years in the electronic messaging and wireless fields, and this research could lead to the filing of further patent applications. If Software.com were to discover that its products violated or potentially violated third party proprietary rights, it might not be able to obtain licenses to continue offering those products without substantial reengineering. Any reengineering effort may not be successful, nor can Software.com be certain that any licenses would be available on commercially reasonable terms.

Substantial litigation regarding intellectual property rights exists in the software industry, and Software.com expects that its software products may be increasingly subject to third-party infringement claims as the number of competitors in its industry segments grows and the functionality of software products in different industry segments overlaps. Any third-party infringement claims could be time-consuming to defend, result in costly litigation, divert management's attention and resources, cause product and service delays or require Software.com to enter into royalty or licensing agreements. Any royalty or licensing arrangements, if required, may not be available on terms acceptable to Software.com, if at all. A successful claim of infringement against Software.com and its failure or inability to license the infringed or similar technology could have a material adverse effect on its business, financial condition, and results of operations.

Employees

As of June 30, 2000, Software.com had 488 full-time employees, 170 of whom were in research and development, 119 in sales and marketing, 140 in services and support and documentation, and 59 in general and administrative. None of its employees is represented by a labor union. It has not experienced any work stoppages, and it considers its relations with its employees to be good.

Legal Matters

From time to time Software.com has been subject to legal proceedings and claims in the ordinary course of business. Although it is not currently involved in any material legal proceedings, Software.com expects that it will in the future be subject to legal disputes, including claims of alleged infringement of third party patents, trademarks, and other intellectual property rights by Software.com or its licensees. Any claims, even if not meritorious, could result in the expenditure of significant financial and managerial resources. Software.com is not aware of any legal proceedings or claims that Software.com believes will have, individually or in the aggregate, a material adverse effect on its business, financial condition, or results of operations.

Facilities

Software.com's corporate headquarters are located in Santa Barbara, California, where it has multiple leases for approximately 43,000 square feet of space in separate office buildings. Software.com's East Coast headquarters are located in Lexington, Massachusetts, where it has a lease for approximately 32,000 square feet of space in a single office building. Software.com leases additional space in San Mateo, California; Bellevue, Washington; and Hauppauge, New York for development personnel. Software.com's primary European operations are located in Naarden, the Netherlands, with an additional office in Windsor, England. Primary Asian operations are located in Tokyo, Japan, and Hong Kong, PRC. In addition to these facilities, Software.com also leases office space for sales personnel in Dallas, Texas; Denver, Colorado; Reston, Virginia; Germany, Australia and Korea. Software.com believes that these existing facilities are adequate to meet current foreseeable requirements or that suitable additional or substitute space will be available on commercially reasonable terms.

SOFTWARE.COM'S MANAGEMENT DISCUSSION
AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

Overview

Software.com is a leading developer and provider of scalable Internet infrastructure software applications. Its products and services are specifically designed to enable service providers to market Internet-based services to businesses and consumers. Software.com has focused on developing carrier-scale, high performance messaging and directory software applications for providers of Internet communications and services. Software.com currently develops, markets, sells, and supports a variety of Internet standards-based messaging and directory software to customers worldwide, including traditional telecommunications carriers, Internet service providers and wholesalers, application service providers, cable-based Internet access providers, competitive local exchange telephone carriers, Internet destination sites or portals and wireless telephony carriers. Software.com has developed three product packages: InterMail Mx, InterMail Kx and Post.Office based on its infrastructure platform. These products allow Software.com's customers to provide a variety of advanced messaging services to their Internet- based consumer and business users.

In April 1999, Software.com completed the acquisition of Mobility.Net Corporation, a California company incorporated in July 1996. Mobility.Net developed an integrated Web mail and calendaring system using a Java-based technology platform that complements Software.com's product offerings. The acquisition of Mobility.Net has been accounted for as a pooling-of-interests. Accordingly, the financial information presented reflects the combined financial position and operations of Software.com and Mobility.Net for all dates and periods presented. In October 1999, Software.com completed the acquisition of Telarc, Inc., which provides carrier-scale Short Messaging Service (SMS) technologies that complement Software.com's product offerings. The acquisition of Telarc Inc. has been accounted for as a purchase. In April 2000, Software.com completed its acquisition of AtMobile.com, Inc., or AtMobile, a leading wireless Internet application service provider with wireless Instant Messaging technology and Wireless Intelligent Network integration expertise. The acquisition of AtMobile has been accounted for as a pooling-of-interests. Accordingly, the financial information presented reflects the combined financial position and operations of Software.com and AtMobile for all dates and periods presented. In June 2000, Software.com completed its acquisition of bCandid Corporation, or bCandid, a market leader in providing carrier-class discussion server infrastructure software to service providers worldwide. The acquisition of bCandid has been accounted for as a purchase.

On August 8, 2000, Software.com signed a definitive merger agreement with Phone.com. Under the terms of the agreement, which was unanimously approved by the Boards of Directors of both companies, stockholders of Phone.com and Software.com will each own approximately 50 percent of the combined company. Each Software.com stockholder will be entitled to receive 1.6105 shares of Phone.com common stock for each share of Software.com common stock. The merger is expected to be accounted for as a pooling of interests and is intended to be tax-free to stockholders of both companies. Subject to stockholder and regulatory approval and other standard closing conditions, the merger is expected to close at the end of fiscal 2000.

Software.com recognizes revenue from sales of software upon delivery of a license key to the customer, provided that persuasive evidence of an arrangement exists, the license fee is fixed and determinable, and collection of the fee is considered probable. If the license agreement has a multi-year term, as is typical with an InterMail Mx contract, or the license fees are calculated based on variable measures, such as the number of mailboxes in use, Software.com recognizes revenue as the customer activates mailboxes on their system. When Software.com enters into a contract where a customer may activate up to a specified number of mailboxes and support and maintenance fees are based on that specified number, it recognizes revenue evenly and ratably as payments become due over the term of the arrangement. When Software.com enters into license agreements under which its revenues are based on a percentage of its customer's revenues, Software.com recognizes revenue as earned and reported by the customer. Revenues from sales to significant resellers are not recognized until the product is sold through to the end user and the license key is issued.

148

Service revenue is composed of revenue from support and maintenance contracts as well as professional services and training. Revenues from support and maintenance contracts are recognized ratably over the term of the support and maintenance period. Substantially all of Software.com's InterMail Mx and InterMail Kx customers purchase support and maintenance, which is paid generally on a quarterly basis. Although the majority of Software.com's Post.Office customers initially purchase an annual support and maintenance contract, a relatively small percentage of these customers renew the contracts after the first year. This is primarily due to the ease of use of the product and the customers' ability to purchase more economical "per-incident" support services. Consulting services revenues are primarily related to deployment services performed on a time-and-materials basis under separate service arrangements. Software.com recognizes revenue, contract costs, and profit on management and consulting contracts for fixed fee contracts on the percentage- completion method. Revenue, contract costs, and profit on time-and-material of-contracts are recorded based upon direct labor hours at fixed hourly rates and cost of materials as incurred. When current estimates of total contract revenue and contract cost indicate a loss, a provision for the entire loss on the contract is recorded. When software and services are billed prior to the time the related revenue is recognized, deferred revenue is recorded.

In a typical InterMail Mx customer relationship, Software.com receives software license revenue, support and maintenance revenue, and professional services revenue. Software.com recognizes these three types of revenue at different stages of its customer relationship. Substantially all of its professional services are performed prior to the activation of mailboxes by the customer. As a result, Software.com generally recognizes revenue from professional services in advance of revenue from software license fees. If a customer has a large number of existing users, Software.com typically sees a large revenue contribution at the time the customer transfers or "migrates" existing user mailboxes to its software platform. After this transfer, the software license revenue primarily reflects the growth in the number of mailboxes on the customer's system. Support and maintenance revenue begins after installation of Software.com's software and also primarily reflects the growth in the number of mailboxes.

Revenues attributable to customers outside of North America accounted for approximately 45% of Software.com's total revenues for the three months ended June 30, 2000. Software.com is making significant expenditures on expansion in Europe and Asia, including the translation of its products for use in these regions, and Software.com expects these expenditures to increase. If Software.com's revenues from international operations do not exceed the expense of establishing and maintaining these operations, Software.com's business, financial condition and operating results will suffer.

Software.com believes its success depends on its ability to execute on its global sales strategy and continue to develop carrier-class products and services that address the unique requirements of service providers. Accordingly, Software.com intends to continue to invest heavily in sales, support, and research and development.

In view of the rapidly changing nature of Software.com's business and its limited operating history, Software.com believes that period-to-period comparisons of revenues and operating results are not necessarily meaningful and should not be relied upon as indications of future performance. Additionally, despite Software.com's sequential quarterly revenue growth during 1999 and 1998, Sofware.com does not believe that its historical growth rates are necessarily sustainable or indicative of future growth. Furthermore, as a result of past acquisitions and future acquisitions that Software.com may make, Software.com expects to incur losses as a result of the amortization of non-cash acquisition related costs for the next several quarters. However, at this time Software.com expects to be operationally profitable, exclusive of one-time cash acquisition related costs and continuing non-cash and/or non- recurring charges.

Comparison of the Six Month Periods Ended June 30, 2000 and 1999

Software Licenses. Software license revenue increased $23.3 million, or 227%, from $10.3 million for the six months ended June 30, 1999 to $33.6 million in the same period in 2000. The increase in software license revenue was primarily due to greater revenue from sales of Software.com's InterMail product offerings, somewhat offset by a decrease in sales of its Post.Office product. The largest contributor to software license revenue continues to be Software.com's InterMail Mx product offering, which grew 321% in the six months ended June 30, 2000 over the same period in 1999. The increase in InterMail Mx revenue was primarily a result of increased growth from existing and new customers. Notably, in the second quarter of 2000, Software.com had a one-time recognition of revenue of approximately $2.0 million relating to previously provisioned mailboxes from one customer who switched from a revenue sharing license agreement to a regular per mailbox provisioning license agreement.

The increase in software license revenue as a percentage of total revenues was primarily related to increased growth in licenses of Software.com's InterMail products from existing and new customers.

150

Services. Services revenue is primarily derived from consulting services, maintenance and support contracts, and training. Services revenue increased $8.3 million, or 109%, from $7.7 million in the six months ended June 30, 1999 to $16.0 million in the same period in 2000. The increase in services revenue for the six months ended June 30, 2000 from the same period in 1999 was primarily due to a $4.5 million increase in professional services as the number of professional services engagements increased and a $3.5 million increase in support and maintenance contracts as Software.com's customer base grew. The number of professional services engagements increased to 65 for the six months ended June 30, 2000 as compared to 30 in the same period in 1999. As a percentage of total revenues, services revenue decreased from 43% in the six months ended June 30, 1999 to 32% in the same period in 2000. This decrease was primarily related to an increase in license revenue of Software.com's InterMail products. In 2000, Software.com expects services revenue as a percentage of total revenues to remain relatively the same as Software.com continues to install its products in service provider customers worldwide.

Cost of Software License Revenue. Cost of software license revenue consists primarily of the cost of third party products integrated into Software.com's products or resold by Software.com and the salaries and related costs for its documentation department and the production of documentation for its InterMail products. Cost of software license revenue increased $200,000, or 18%, from $1.1 million in the six months ended June 30, 1999 to $1.3 million in the same period in 2000. The increase was primarily due to an increase in the size of Software.com's documentation department as well as increased investment in product translation for Software.com's international markets.

Cost of Services Revenue. Cost of services revenue includes salaries and related costs of Software.com's consulting services, customer support and training organizations, cost of third parties contracted to provide consulting services to Software.com's customers, and an allocation of its facilities and depreciation expenses. Cost of services revenue increased $6.3 million, or 107%, from $5.8 million in the six months ended June 30, 1999 to $12.1 million in the same period in 2000. The increase in cost of services was primarily due to an increase in Software.com's consulting and support organizations from 58 employees at June 30, 1999 to 121 employees at June 30, 2000 to support its larger customer base.

Sales and Marketing. Sales and marketing expense consists primarily of salaries and benefits of Software.com's sales, marketing, product management and business development organizations, sales commissions, marketing programs, and an allocation of Software.com's facilities and depreciation expenses. Sales and marketing expense increased by $7.5 million, or 90%, from $8.2 million in the six months ended June 30, 1999 to $15.7 million in the same period in 2000. The increase in sales and marketing expense was primarily due to growth in Software.com's global sales and product management organizations as well as an increase in marketing programs. The total number of employees in the sales and marketing organization increased from 72 at June 30, 1999 to 119 at June 30, 2000. The decrease in sales and marketing as a percentage of total revenues was primarily due to increased growth in license revenue from existing customers. Software.com expects its sales and marketing expenses will increase in absolute dollars in future periods due to the planned expansion of its international sales and marketing operations.

Research and Development. Research and development expense consists primarily of salaries and benefits of Software.com's engineering and quality assurance organizations, and an allocation of Software.com's facilities and depreciation expenses. Research and development expense increased by $5.9 million, or 86%, from $6.8 million in the six months ended June 30, 1999 to $12.7 million in the same period in 2000. The increase in research and development expense was primarily due to an increase in Software.com's development organization from 99 employees at June 30, 1999 to 170 employees at June 30, 2000. The decrease in research and development as a percentage of total revenues was primarily due to increased growth in license revenue from existing customers. Software.com believes continued investment in research and development is essential to its future success, and Software.com expects its research and development expenses to increase in absolute dollars in future periods with the growth in demand of unified and wireless messaging products.

151

General and Administrative. General and administrative expense consists primarily of salaries and benefits of Software.com's finance, human resources and legal services organizations, third party legal, accounting, and other professional services fees, an allocation of Software.com's facilities and depreciation expenses and bad debt expense. General and administrative expense increased by $2.7 million, or 87%, from $3.1 million in the six months ended June 30, 1999 to $5.8 million in the same period in 2000. The increase in general and administrative expense was primarily related to an increase in Software.com's general and administrative organization from 42 employees at June 30, 1999 to 59 employees at June 30, 2000 as well as fees for accounting and legal services and reserves for bad debts. The decrease in general and administrative as a percentage of total revenues was primarily due to increased growth in license revenue from existing customers. Software.com expects general and administrative expenses to increase in absolute dollars but decrease slightly as a percentage of total revenues in future periods.

Stock Based Compensation--Acquisition Related Expense. Stock based compensation-acquisition related expense consists primarily of charges recorded for the underlying value of warrants issued by recently acquired AtMobile in conjunction with a Web development, hosting, maintenance and licensing agreement entered into with a contractor in late 1999. The charges recorded for the six months ended June 30, 2000 was $3.6 million. Software.com will continue to record related charges based on the underlying value of the warrants as the warrants continue to vest.

Amortization of Goodwill and Purchased Intangible Assets. In June 2000, Software.com completed its acquisition of bCandid. The acquisition was accounted for as a purchase and, accordingly, bCandid's operating results have been included in Software.com's consolidated financial statements results from the acquisition date. The purchase price plus costs directly attributable to the completion of the acquisition have been allocated to the assets and liabilities acquired based on their approximate fair market value. Using proven valuation procedures and techniques in an independent appraisal, a portion of the purchase price was identified as intangible assets as follows:
$300,000 to a covenant not to compete, $400,000 to assembled workforce, $600,000 to customer relationships, $6.7 million to developed technology, and $55.9 million to goodwill. Goodwill and identified intangibles are being amortized on a straight-line basis over their estimated economic useful lives of two to four years. Additionally, in October 1999, Software.com completed its acquisition of Telarc, Inc. ("Telarc") which also had a portion of the purchase price identified as intangible assets allocated as follows: $263,000 to net intangible assets, $5.7 million to developed technology, $125,000 to assembled workforce and other intangibles and $2.3 million to goodwill. Goodwill and identified intangibles from the Telarc acquisition are being amortized on a straight-line basis over their estimated economic useful lives of three to five years. The Company recorded $1.7 million of amortization of goodwill and other intangibles related to these acquisitions for the six months ended June 30, 2000.

Purchased In-Process Research and Development. Software.com obtained an independent appraisal using proven valuation procedures and techniques for the acquisition of bCandid. The appraisal allocated a portion of the acquired business to in-process research and development. This acquired technology had not yet reached technological feasibility and had no alternative future uses. Accordingly, the Company wrote off $2.0 million at the time of the acquisition.

Acquisition Related Costs. Acquisition related costs consist primarily of investment banker fees associated with the close of acquisitions as well as legal and accounting professional services fees. The Company recorded 10.4 million of acquisition related costs for the six months ended June 30, 2000.

Interest and Other Income (Expense), Net. Interest and other income (expense), net consists primarily of interest income from Software.com's cash and short-term investments net of interest associated with a credit facility Software.com had in 1999. Total other income (expense) increased $2.6 million, from an expense of $500,000 in the six months ended June 30, 1999 to income of $2.1 million in the same period in 2000. The increase in both periods was primarily related to interest earned on the proceeds of Software.com's initial public offering of common stock in June 1999.

152

Provision for Income Taxes. Provision for income taxes consists mainly of foreign withholding and income taxes. Provision for income taxes increased $210,000 from $146,000 in the six months ended June 30, 1999 to $356,000 in the same period in 2000. The increase was related to Software.com's continued expansion into foreign tax withholding jurisdictions.

Stock-Based Compensation. Software.com recorded deferred compensation of approximately $770,000 and $1.5 million in 1999 and 1998, respectively, representing the difference between the exercise prices of options granted to employees during 1999 and 1998 and the deemed fair value for accounting purposes of Software.com's common stock on the grant dates. Software.com amortized deferred compensation expense of $304,000 during the six months ended June 30, 2000 compared to $240,000 for the same period in 1999. This compensation expense relates to options awarded to individuals in all operating expense categories.

Comparison of Years Ended December 31, 1999 and 1998

Software Licenses. Software license revenue increased $9.3 million, or 53%, from $17.5 million in 1998 to $26.8 million in 1999. The increase in software license revenue was primarily due to greater revenue from sales of Software.com's InterMail product offerings, somewhat offset by a decrease in sales of Software.com's Post.Office product. The largest contributor to software license revenue continues to be Software.com's InterMail Mx product offering, which grew 56% in 1999 over 1998. The increase in InterMail Mx revenue was primarily a result of increased growth from existing and new customers and to a lesser extent large migrations of mailboxes from other existing platforms of new customers.

Software.com's InterMail Kx product was introduced in March of 1999 and overlaps to some extent with Software.com's Post.Office product. Both products are targeted at small and medium size service providers worldwide. Combined revenues from Post.Office and InterMail Kx resulted in a 57% increase from 1998 to 1999, however revenues from Post.Office decreased 27% from 1998 to 1999. Software.com expects revenues from Post.Office to continue to decrease as sales of its InterMail Kx product offering increase.

The decrease in software license revenue as a percentage of total revenues was primarily related to an increase in support and maintenance from ongoing and new contracts, and increase in professional services engagements contributed from Software.com's AtMobile acquisition and to a lesser extent a decrease in migrations of mailboxes from new customers from 1998 to 1999. In 1999 Software.com had seven migrations of InterMail Mx customers compared to 13 in 1998.

Services. Services revenue increased $10.8 million, or 116%, from $9.3 million in 1998 to $20.1 million in 1999. The increase in services revenue for 1999 as compared to 1998 was primarily due to a $5.6 million increase in professional services as the number of professional services increased, coupled with the increased engagements contributed from Software.com's AtMobile acquisition, and a $4.9 million increase in support and maintenance contracts as Software.com's customer base grew. As a percentage of total revenues, services revenue increased to 43% in 1999 from 35% in 1998. This increase was primarily related to an increased number of professional services engagements associated with new and existing contracts as well as support and maintenance from ongoing and new contracts. In 2000 Software.com expects services revenue as a percentage of total revenues to decrease to some extent as a result of continued growth in license revenue relative to growth in services revenue.

Cost of Software License Revenue. Cost of software license revenue increased $1.1 million, or 69%, from $1.6 million in 1998 to $2.7 million in 1999. The increase was primarily due to an increase in Software.com's documentation department as well as increased investment in product translation for its international markets. Additionally, in 1999 Software.com resold a third party database to eight of its InterMail Mx customers, with the cost of that software included in cost of software license revenue in 1999. In 1998, Software.com resold a third-party database to five of its customers.

Cost of Services Revenue. Cost of services revenue increased $4.7 million, or 52%, from $9.0 million in 1998 to $13.7 million in 1999. The increase in cost of services was primarily due to an increase in

153

Software.com's consulting and support organizations from 54 employees at December 31, 1998 to 83 employees at December 31, 1999 to support Software.com's larger customer base. The improvement in gross margin on services revenue from 3% for 1998 to 32% in 1999 was substantially attributable to improved margins on Software.com's professional service engagements as contributed from Software.com's AtMobile acquisition.

Sales and Marketing. Sales and marketing expense increased by $7.4 million, or 60%, from $12.3 million in 1998 to $19.7 million in 1999. The increase in sales and marketing expense was primarily due to an increase in sales commissions commensurate with the increase in revenues as well as growth in Software.com's global sales organization. The total number of employees in the sales and marketing organization increased from 64 at December 31, 1998 to 83 at December 31, 1999. Software.com expects its sales and marketing expenses will increase in absolute dollars in future periods due to the planned expansion of its international sales and marketing operations.

Research and Development. Research and development expense increased by $3.8 million, or 31%, from $12.1 million in 1998 to $15.9 million in 1999. The increase in research and development expense was primarily due to an increase in Software.com's development organization from 93 employees at December 31, 1998 to 122 employees at December 31, 1999. Software.com believes continued investment in research and development is essential to its future success, and Software.com expects its research and development expenses to increase in absolute dollars in future periods with the growth in demand of unified and wireless messaging products.

General and Administrative. General and administrative expense increased by $2.2 million, or 37%, from $5.9 million in 1998 to $8.1 million in 1999. The increase in general and administrative expense for 1999 was primarily related to fees for accounting and legal services, increased reserves for bad debts, and an increase in Software.com's general and administrative organization from 34 employees at December 31, 1998 to 45 employees at December 31, 1999. Software.com expects general and administrative expenses to decrease as a percentage of total revenues in future periods.

General and Administrative--Non-Cash Expense. Charges of $125,000 were recorded for the year ended December 31, 1999. Software.com will continue to record related charges based on the underlying value of the warrants as the services are provided and the warrants continue to vest.

Acquisition costs. In April, 1999, Software.com completed the acquisition of Mobility.Net, Inc. which offers products for Web messaging using a Java-based technology platform that complement Software.com's product offerings. Software.com issued 1,579,000 shares of its common stock in exchange for all of the outstanding shares of Mobility.Net. The acquisition was accounted for as a pooling-of-interests. Accordingly, the financial information presented reflects the combined financial position and operations of Software.com and Mobility.Net for all dates and periods presented.

In October, 1999, Software.com acquired Telarc, Inc., which provides carrier-scale Short Messaging Service (SMS) technologies that complement Software.com's product offerings. In exchange for all of the issued and outstanding stock of Telarc, Software.com issued 212,000 shares of Software.com common stock and $1.5 million in cash. The acquisition of Telarc was accounted for as a purchase and, accordingly, the acquired assets and liabilities were recorded at their estimated fair values at the date of acquisition. Telarc's operating results have been included in Software.com's consolidated financial statements results from the acquisition date of October 20, 1999. The purchase price plus costs directly attributable to the completion of the acquisition have been allocated to the assets and liabilities acquired based on their approximate fair market value. A significant portion of the purchase price was identified as intangible assets in an independent appraisal using proven valuation procedures and techniques. The appraisal of the acquired business included $3.2 million of purchased in- process research and development (IPR&D). This acquired technology had not yet reached technological feasibility and had no alternative future uses. Accordingly, it was written off at the time of the acquisition. The remainder of the purchase price was allocated as follows: $263,000 to net intangible assets, $5.7 million to developed technology, $125,000 to assembled workforce and other intangibles and $2.3 million to goodwill. Goodwill and identified intangibles are being amortized on a straight-line basis over their estimated economic useful lives of three to five years.

154

On the date of its acquisition, Telarc's technology was classified between core or developed technology and IPR&D. Three principal Telarc products were identified and their reliance on the developed technology and IPR&D was determined. IPR&D was further analyzed to determine: (1) the estimated time required to complete the development, (2) the estimated cost to complete and
(3) the complexity involved in overcoming technological obstacles that must be resolved during development. The completion of in-process development at the time of the acquisition ranged from 50% to 86%. Software.com's management estimates the cost to complete the development effort to be approximately $1.8 million as of December 31, 1999 and the release of the products incorporating these technologies to occur during the fourth quarter of 2000.

These IPR&D valuations represent the five year after-tax cash flow of this technology using a discounted rate of 40%. In valuing the developed technology and IPR&D, the initial focus was on the revenue contribution generated by each of the products. Revenue estimates were based on the following: (1) aggregate revenue growth rates for the business as a whole, (2) individual product revenues, (3) growth rates for related products, (4) anticipated product development and introduction schedules, (5) product sales cycles and (6) the estimated useful life of a product's underlying technology. The aggregate product revenue amounts were estimated and segregated between the developed technology and IPR&D. Operating expenses were deducted from the revenue estimates to arrive at operating income. Operating expenses include cost of revenue, selling and marketing, and general and administrative expenses but no non-cash charges such as depreciation and amortization. Certain adjustments were made to operating income to derive the after-tax cash flow. These adjustments included the calculation of an applicable tax expense and an appropriate charge for the use of contributory assets necessary to generate revenue and operating income associated with the subject intangible assets.

Software.com believes that it is positioned to complete development of the Telarc technology and products, however there is a risk that Software.com may not be able to complete these projects within the estimated timeframe or cost budget. Furthermore, there is no assurance that any product will meet with either technological or commercial success. See "Risk Factors" for further information.

Legal Matter. Software.com was involved in a contract dispute with a third party technology partner under a 1996 licensing agreement. The dispute related to a minimum royalty obligation of $1,000,000 purportedly owed by Software.com to the third party. In 1997, Software.com accrued $1,000,000 for its potential exposure under the claim. In February 1999, the parties entered into an agreement to settle all outstanding claims. Software.com paid the third party $400,000, and as a result the related accrual was reduced to $600,000 at December 31, 1998 to reflect the complete resolution of this matter.

Other Income (Expense). Other income (expense) consists primarily of interest income from Software.com's cash and short-term investments net of interest associated with its credit facility. Total other income (expense) increased $1.6 million, from an expense of $536,000 for 1998 to income of $1.0 million in 1999. The increase was primarily related to interest earned on the proceeds of its initial public offering of common stock in June of 1999.

Provision for Income Taxes. Provision for income taxes consists mainly of foreign withholding and income taxes. Provision for income taxes decreased $234,000 from $446,000 in 1998 to $212,000 in 1999. The decrease was primarily related to the completion of a large professional services engagement in Canada in 1998 that resulted in withholding and income taxes during that period.

As of December 31, 1999, Software.com had federal and state net operating loss carryforwards of approximately $40.9 million and $11.1 million, respectively. The net operating loss and credit carryforwards will expire at various dates beginning in 2011 through 2019 for federal and 2002 to 2004 for state, if not utilized. On December 31, 1999, Software.com also had federal and state research and development tax credit carryforwards of approximately $613,000 and $188,000, expiring in 2011 to 2014. Software.com also has a foreign tax credit of approximately $484,000, which will expire in 2003. As a result of changes in Software.com's equity ownership resulting from its convertible preferred stock financings and its initial public offering, utilization of the net operating losses and tax credits may be subject to substantial annual limitations. This is due to the

155

ownership change limitations provided by the Internal Revenue Code of 1986, as amended, and similar state provisions. The annual limitation may result in the expiration of net operating losses and tax credits before utilization. See Note 6 of Notes to Consolidated Financial Statements.

Stock-based Compensation. Software.com recorded deferred compensation of approximately $1.5 million and $770,000 in 1998 and 1999, respectively, representing the difference between the exercise prices of options granted to employees during 1998 and 1999 and the deemed fair value for accounting purposes of Software.com's common stock on the grant dates. Software.com amortized deferred compensation expense of $544,000 during 1999. This compensation expense relates to options awarded to individuals in all operating expense categories. Total deferred compensation at December 31, 1999 of $1.67 million is being amortized over the vesting periods of the options. The amortization of deferred compensation recorded will approximate $600,000, $521,000, $480,000, and $47,000 for the years 2000, 2001, 2002 and 2003.

Comparison of Years Ended December 31, 1998 and 1997

Software Licenses. Software licenses revenue increased $9.6 million, or 122%, from $7.9 million in 1997 to $17.5 million in 1998. The increase in software license revenue was primarily due to an increase in the number of service providers worldwide using InterMail Mx for their consumer email offering. Software license revenue from InterMail Mx increased 291% from 1997 to 1998. In addition, software license revenue from Post.Office increased 36% from 1997 to 1998 as Software.com continued to expand sales of Post.Office into the small to medium size service provider market. During 1998, Software.com received $619,000 of software license revenue from the resale of a third party database to its InterMail Mx customers as compared to $94,000 during 1997.

Services. Services revenue increased $6.3 million, or 210%, from $3.0 million in 1997 to $9.3 million in 1998. As a percentage of total revenues, services revenue increased from 27% in 1997 to 35% in 1998. The increase in services revenue was substantially due to an increase in professional services revenue from 1997 to 1998 as the number of consulting projects increased, including a large InterMail Mx installation for which Software.com recognized $2.4 million in services revenue. In addition, in 1998 there were an increased number of professional services engagements contributed through the acquisition of AtMobile.

In addition, support and maintenance revenue increased 116% from 1997 to 1998 as Software.com's customer base grew. The increase in services revenue as a percentage of total revenues was primarily due to the recognition of services revenue from this large InterMail Mx installation.

Cost of Software License Revenue. Cost of software license revenue increased by $879,000, or 128%, from $689,000 in 1997 to $1.6 million in 1998. This increase was primarily due to a $433,000 increase resulting from the resale of third party software used in conjunction with Software.com's InterMail Mx product and, to a lesser extent, a $317,000 increase due to growth in the number of employees in Software.com's documentation department.

Cost of Services Revenue. Cost of services revenue increased by $6.3 million, or 233%, from $2.7 million in 1997 to $9.0 million in 1998. Cost of services during this period increased commensurate with the increase in the number of professional services deployments.

Sales and Marketing. Sales and marketing expense increased by $3.5 million, or 40%, from $8.8 million in 1997 to $12.3 million in 1998. Substantially all of this increase was due to significant expansion in Software.com's global direct sales organization, primarily in North America. The total number of employees in the sales and marketing organization increased from 42 at the end of 1997 to 64 at the end of 1998. The decrease in sales and marketing expense as a percentage of total revenues from 81% in 1997 to 46% in 1998 was primarily due to the recognition of InterMail Mx software licenses revenue from contracts signed in 1997.

Research and Development. Research and development expense increased by $5.4 million, or 81%, from $6.7 million in 1997 to $12.1 million in 1998. The increase in research and development expense was primarily

156

due to costs associated with the development and testing of Software.com's new InterMail Kx product package, which was introduced in March 1999, and, to a lesser extent, the cost of porting Software.com's InterMail messaging technology to the Hewlett-Packard and IBM Unix platforms. The decrease in research and development as a percentage of total revenues from 62% in 1997 to 45% in 1998 was primarily due to an increase in software licenses revenue from products developed in previous periods.

General and Administrative. General and administrative expense increased by $2.4 million, or 69%, from $3.5 million in 1997 to $5.9 million in 1998. The increase in general and administrative expense was due in significant part to increased depreciation related to operations in new facilities as well as a $431,000 increase in the provision for doubtful accounts. The decrease in general and administrative costs as a percentage of total revenues from 32% in 1997 to 22% in 1998 was primarily due to Software.com's increase in software license revenue.

Legal Matter. Software.com accrued in 1997 for an asserted claim related to a minimum royalty obligation of $1 million purportedly owed by Software.com under a licensing agreement with a third party technology partner. In February 1999, Software.com and the third party entered into an agreement to settle all outstanding claims. Under the settlement agreement, Software.com agreed to pay the third party a minimum of $400,000, with a contingent obligation to pay an additional $200,000 if Software.com did not take certain actions prior to December 31, 1999.

Other Income (Expense). Other income (expense) consists primarily of interest expense associated with Software.com's credit facility and interest income on short-term investments. Total other income (expense) increased $808,000, from income of $272,000 for 1997 to expense of $536,000 in 1998. The increase was primarily related to an increase in interest paid for Software.com's credit facility. The credit facility was opened in November 1997, resulting in only two months of interest expense for 1997.

Provision for Income Taxes. For the year ended December 31, 1998, Software.com had a tax provision of $446,000 related to foreign withholding taxes.

Liquidity and Capital Resources

Software.com has funded its operations primarily through the private placement of equity securities and the initial public offering of shares, and raised net proceeds of approximately $79.8 million in 1999. At June 30, 2000, Software.com's principal sources of liquidity included approximately $41.7 million of cash and cash equivalents and $45.7 million of marketable securities.

Net cash used in operating activities for the six months ended June 30, 2000 was primarily due to Software.com's net loss of $13.9 million which included acquisition-related investment banker fees of $10.3 million and was also due to an increase in accounts receivable of $7.3 million, primarily offset by increases in deferred revenue of $9.1 million, non-employee equity-based compensation of $3.6 million and depreciation and amortization of $3.4 million. Cash used in operating activities for the same period in 1999 was primarily due to Software.com's net loss of $7.6 million, partially offset by an increase in accounts payable of $2.0 million.

Net cash used in investing activities for the six months ended June 30, 2000 was primarily due to purchases (net of maturities) of marketable securities of $20.0 million as well as $5.7 million in the acquisition of property and equipment. Cash used in investing activities for the same period in 1999 was primarily due to purchases (net of maturities) of marketable securities of $2.5 million.

Net cash provided by financing activities for the six months ended June 30, 2000 was primarily due to the issuance of $12.5 million of preferred stock by AtMobile and $9.0 million in exercises of stock options. Cash provided by financing activities for the same period in 1999 was primarily due to $68.0 million in net proceeds from the issuance of common stock in Software.com's initial public offering and the issuance of $10.0 million of preferred stock, partially offset by $5.0 million in repayments (net of proceeds) of long-term debt and notes payable to bank.

157

Software.com believes that its existing cash and marketable securities balanced together with cash generated from operations will be sufficient to meet its working capital, financing and capital expenditure needs for at least the next twelve months. Software.com continues to evaluate the potential acquisition of key technology, complementary product lines and other companies. If Software.com decides to proceed with any such acquisitions, they may be financed by a variety of sources, including equity or debt financing.

Effect of Recent Accounting Pronouncements

In December 1999, the SEC issued Staff Accounting Bulletin No. 101, or SAB 101, "Revenue Recognition in Financial Statements." SAB 101 summarizes certain of the SEC's views in applying generally accepted accounting principles to revenue recognition in financial statements. The company is required to adopt SAB 101 in the first quarter of fiscal 2001. Management does not expert the adoption of SAB 101 to have a material effect on the company's operation or financial position.

Quantitative and Qualitative Disclosure about Market Risk

Software.com develops products in the United States and sell in North America, South America, Asia and Europe. As a result, Software.com's financial results could be affected by factors such as changes in foreign currency exchange rates or weak economic conditions in foreign markets. As all sales are currently made in U.S. dollars, a strengthening of the dollar could make Software.com's products less competitive in foreign markets. Software.com's interest income is sensitive to changes in the general level of U.S. interest rates, particularly since the majority of its investments are in short-term instruments. Due to the nature of Software.com's short- term investments and debt, Software.com has concluded that there is no material market risk exposure.

Software.com Employment Agreements and Change of Control Agreements

Software.com does not have any employment agreements with any of its executive officers named in the Software.com Summary Compensation Table. Software.com has, however, entered into "change of control" agreements with each of its executive officers named in the Software.com Summary Compensation Table and with other officers and key employees. These agreements provide that if an officer's employment is terminated as a result of an "involuntary termination" during a period beginning two months before, and ending six months after a change of control, then one-half of the unvested portion of any stock option held by the officer will accelerate and become exercisable, subject to certain limitations. The merger with Phone.com may constitute a change control. For purposes of the agreement, "involuntary termination" includes a change in the nature or scope of the officer's duties that is inconsistent with the position held by the officer immediately before the change of control, a material reduction of benefits or perquisites, a reduction in base cash salary, a relocation that is more than 20 miles from the officer's present location, any purported termination of the officer by Software.com, or the failure by Software.com to obtain the assumption of the change of control agreement.

Software.com Employee Benefit Plans

1995 Stock Plan

Software.com's 1995 stock plan, as amended and restated, allows Software.com to grant to employees incentive stock options within the meaning of Section 422 of the Internal Revenue Code and to grant to employees, directors and consultants nonstatutory stock options and stock purchase rights. Unless terminated sooner, the plan will automatically terminate in 2005. Software.com's board of directors approved the plan in October 1995 and Software.com's stockholders approved the plan in January 1996. The plan was most recently amended by Software.com's board of directors in May 1999 and approved by Software.com's stockholders in June 1999. A total of 12,448,931 shares of common stock is reserved for issuance under the plan, plus annual increases, to be added on July 1 of each year, equal to the lesser of:

. 5,000,000 shares;

. 4% of the outstanding shares on such date; or

. a lesser amount determined by the board.

Software.com's board of directors or an administrator appointed by the board may administer the 1995 stock plan. The plan administrator has the power to determine the terms and conditions of the options and stock purchase rights granted, including:

. the exercise price;

. the number of shares of common stock subject to each option and stock purchase right;

. the exercisability thereof; and

. the form of consideration payable upon the exercise of the option.

In addition, Software.com's board of directors has the authority to amend, suspend or terminate the plan, provided that no action may affect any share of common stock previously issued and sold or any option previously granted under the plan.

Options and purchase rights granted under Software.com's 1995 stock plan are not generally transferable by the optionee. Each option is exercisable during the lifetime of the optionee only by the optionee. Options granted under Software.com's 1995 stock plan must generally be exercised within three months of the end of optionee's status as an employee, consultant or director of Software.com, or within twelve months after the optionee's termination by death or disability. However, an option may never be exercised later than the expiration of its term.

The exercise price of all incentive stock options granted under the plan is determined by the administrator, but must be at least equal to the fair market value of the common stock on the date of grant. With respect to any participant who owns stock possessing more than 10% of the voting power of all classes of Software.com's outstanding capital stock, the exercise price of any incentive stock option granted must equal at least 110% of the fair market value on the grant date. The exercise price of nonstatutory stock options granted under the plan is determined by the administrator, but must be equal to at least 85% of the fair market value on the grant date. With respect to any participant who owns stock possessing more than 10% of the voting power of all classes of Software.com's outstanding capital stock, the exercise price of any nonstatutory stock option granted must equal at least 110% of the fair market value on the grant date. The term of all other options granted under the 1995 stock plan may not exceed ten years. However, the term of incentive stock options granted to any participant who owns stock with more than 10% of the voting power of all classes of Software.com's outstanding capital stock cannot exceed five years.

Software.com's 1995 stock plan provides that in the event of a merger of Software.com with or into another corporation, each outstanding option or purchase right shall be assumed or an equivalent option or right substituted by the successor corporation. If the outstanding options or rights are not assumed or substituted as described in the preceding sentence, the options or rights shall terminate as of the date of the merger.

162

2000 NonStatutory Stock Option Plan

Software.com established the 2000 nonstatutory stock option plan in order to provide additional incentive to its employees and consultants. Options granted under Software.com's 2000 nonstatutory stock option plan will be nonstatutory stock options and are not intended to qualify as incentive stock options within the meaning of Section 422 of the Internal Revenue Code. Options may be granted to employees and consultants, but not to officers and directors of Software.com. A total of 2,050,000 shares of common stock has been reserved for issuance under the 2000 nonstatutory stock option plan.

Options and purchase rights granted under Software.com's 2000 nonstatutory stock option plan are not generally transferable by the optionee. Each option is exercisable during the lifetime of the optionee only by the optionee. Options granted under Software.com's 2000 nonstatutory stock option plan must generally be exercised within three months of the end of optionee's status as an employee, consultant or director of Software.com, or within twelve months after the optionee's termination by death or disability. However, an option may never be exercised later than the expiration of its term.

Software.com's 2000 nonstatutory stock option plan provides that in the event of a merger of Software.com with or into another corporation, each outstanding option or purchase right shall be assumed or an equivalent option or right substituted by the successor corporation. If the outstanding options or rights are not assumed or substituted as described in the preceding sentence, the options or rights shall terminate as of the date of the merger.

The 2000 nonstatutory stock option plan will terminate in 2010. The board of directors has the authority to amend or terminate the 2000 nonstatutory stock option plan, except that no such action may adversely affect any optionee.

1999 Employee Stock Purchase Plan

Software.com's 1999 employee stock purchase plan was adopted by Software.com's board of directors in May 1999 and approved by its stockholders in June 1999. A total of 1,000,000 shares of common stock has been reserved for issuance under the purchase plan, plus annual increases, to be added the first day of each fiscal year commencing in 2001, equal to the lesser of:

. 500,000 shares;

. 2% of the shares outstanding on that date; or

. a lesser amount determined by the board.

The purchase plan, which is intended to qualify under Section 423 of the Internal Revenue Code of 1986, as amended, contains successive twenty-four month offering periods. The offering periods generally start on the first trading day on or after May 1 and November 1 of each year, except for the first such offering period which commences on the first trading day on or after the effective date of this offering and ends on the trading day on or before April 30, 2001.

Employees are eligible to participate if they are employed by Software.com or any participating subsidiary for at least 20 hours per week and for more than five months in any calendar year. However, the following employees may not be granted options to purchase stock under the purchase plan:

. any employee who immediately after grant owns stock possessing 5% or more of the total combined voting power or value of all classes of Software.com's capital stock, or

. any employee whose rights to purchase stock under all Software.com's employee stock purchase plans accrues at a rate which exceeds $25,000 worth of stock for each calendar year.

Participants may purchase common stock through payroll deductions of up to 15% of the participant's compensation. The maximum number of shares a participant may purchase during a single offering period is 10,000 shares.

163

Amounts deducted and accumulated by the participant are used to purchase shares of Software.com's common stock at the end of each offering period. The price of stock purchased under the purchase plan is 85% of the lower of the fair market value of the common stock at the beginning of the offering period and the end of each purchase period.

The purchase plan provides that, in the event Software.com merges with or into another corporation or a sale of substantially all of Software.com's assets, each outstanding option may be assumed or substituted by the successor corporation. If the successor corporation refuses to assume or substitute for the outstanding options, the offering period then in progress will be shortened and a new exercise date will be set, which will occur before the proposed sale or merger.

The purchase plan will terminate in 2009. The board of directors has the authority to amend or terminate the purchase plan, except that no such action may adversely affect any outstanding rights to purchase stock.

401(k) Plan

In 1996, Software.com adopted a 401(k) Retirement Savings and Investment Plan covering its full-time employees located in the United States. The plan is intended to qualify under Section 401(k) of the Internal Revenue Code of 1986, as amended, so that (a) contributions to the plan by employees or by Software.com, and the investment earnings thereon, are not taxable to employees until withdrawn from the plan, and so that (b) contributions by Software.com, if any, will be deductible by Software.com when made. Under the plan, eligible employees may elect to make payroll deductions up to 20% of their compensation, up to the statutorily prescribed annual limit ($10,500 in 2000) and to have the amount of their deduction contributed to the plan. The plan permits, but does not require, additional matching contributions by Software.com on behalf of all participants. To date, Software.com has not made any matching contributions to the plan.

Software.com Limitations of Liability and Indemnification

Software.com's certificate of incorporation limits the liability of directors to the maximum extent permitted by Delaware law. Delaware law provides that directors of a corporation will not be personally liable for monetary damages for breach of their fiduciary duties as directors, except liability for (i) any breach of their duty of loyalty to the corporation or its stockholders, (ii) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) unlawful payments of dividends or unlawful stock repurchases or redemption, or (iv) any transaction from which the director derived an improper personal benefit. The limitation of liability does not apply to liabilities arising under the federal securities laws and does not affect the availability of equitable remedies such as injunctive relief or rescission.

Software.com's bylaws provide that Software.com shall indemnify its directors and officers and may indemnify its employees and other agents to the fullest extent permitted by law. Software.com believes that indemnification under its bylaws covers at least negligence and gross negligence on the part of indemnified parties. Software.com's bylaws also permit Software.com to secure insurance on behalf of any officer, director, employee or other agent for any liability arising out of his or her actions in such capacity, regardless of whether the bylaws would permit indemnification.

Software.com has entered into agreements to indemnify Software.com's directors and officers, in addition to indemnification provided for in Software.com's bylaws. These agreements, among other things, provide for indemnification of Software.com's directors and officers for certain expenses (including attorneys' fees), judgments, fines and settlement amounts incurred by any such person in any action or proceeding, including any action by or in the right of Software.com, arising out of the person's services as a director or officer of Software.com, any of Software.com's subsidiaries or any other company or enterprise to which the person provides services at Software.com's request. Software.com believes that these provisions and agreements are necessary to attract and retain qualified persons as directors and officers.

The following table sets forth certain information with respect to the beneficial ownership of the common stock of Software.com as of July 31, 2000, of:

. each current director of Software.com;

. Software.com's executive officers named in the Software.com Summary Compensation Table; and

. all of Software.com's current directors and executive officers as a group.

Beneficial ownership is determined in accordance with the rules of the Securities and Exchange Commission.

Such shares, however, are not deemed outstanding for the purpose of computing the percentage ownership of any other person.

Unless otherwise indicated, the address of each individual listed in the table is Software.com, Inc., 525 Anacapa Street, Santa Barbara, CA 93101.

As of July 31, 2000, there were 82,997,462 shares of common stock outstanding that were held of record by approximately 600 stockholders, and no shares of preferred stock were outstanding.

Common Stock

The holders of common stock are entitled to one vote per share on all matters to be voted upon by the stockholders. Subject to preferences that may be applicable to any outstanding preferred stock, the holders of Phone.com common stock are entitled to receive ratably any dividends that may be declared from time to time by the board of directors out of funds legally available therefor. In the event of a liquidation, dissolution or winding up of Phone.com, the holders of common stock are entitled to share ratably in all assets remaining after payment of liabilities, subject to prior rights of preferred stock, if any, then outstanding. The Phone.com common stock has no preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions available to the common stock. All outstanding shares of common stock are fully paid and non-assessable.

Preferred Stock

Phone.com is authorized to issue 5,000,000 shares of undesignated preferred stock. The Phone.com board of directors will have the authority to issue the undesignated preferred stock in one or more series and to determine the powers, preferences and rights and the qualifications, limitations or restrictions granted to or imposed upon any wholly unissued series of undesignated preferred stock and to fix the number of shares constituting any series and the designation of a series, without any further vote or action by the stockholders. The issuance of preferred stock may have the effect of delaying, deferring or preventing a change in control of Phone.com without further action by the stockholders and may adversely affect the voting and other rights of the holders of common stock. At present, Phone.com has no plans to issue any shares of preferred stock.

Registration Rights of Stockholders

The holders of approximately 1,437,000 shares of common stock of Phone.com are entitled to rights to register these shares under the Securities Act pursuant to an agreement between Phone.com and the holders of such shares, entered into in connection with Phone.com's acquisition of Apion. Subject to the limitations in this agreement, the holders of the shares may require, on one occasion at any time before October 25, 2001, that Phone.com use its best efforts to register the shares for public resale, provided that the proposed aggregate offering price is in excess of $1,000,000. All of the fees, costs and expenses incurred in connection with the registration must be borne by Phone.com and all of the selling expenses, including underwriting discounts, selling commissions and stock transfer taxes, relating to shares must be borne by the holders of the shares being registered.

The holders of 3,103,692 shares of common stock of Phone.com are entitled to rights to register these shares under the Securities Act pursuant to an agreement between Phone.com and the holders of such shares, entered into in connection with Phone.com's acquisition of Paragon. Subject to the limitations in this agreement, the

168

holders of the shares may require, on one occasion at any time before February 8, 2002, that Phone.com use its best efforts to register the shares for public resale, provided that the proposed aggregate offering price is in excess of $1,000,000. All of the fees, costs and expenses incurred in connection with the registration of the shares and all of the selling expenses, including underwriting discounts, selling commissions and stock transfer taxes, up to $50,000 must be borne by Phone.com. All of the expenses selling expenses in excess of $50,000 relating to the shares must be borne by the holders of the shares being registered.

The holders of 193,873 shares of common stock of Phone.com are entitled to rights to register these shares under the Securities Act pursuant to an agreement between Phone.com and the holders of such securities, entered into in connection with Phone.com's acquisition of MyAble. Pursuant to this agreement, if Phone.com registers any of its common stock either for its own account or for the account of other security holders, the holders of registrable securities are entitled to include their shares of common stock in the registration. A holder's rights to include shares in an underwritten registration is subject to the ability of the underwriters to limit the number of shares included in the offering.

Warrants

As of June 30, 2000, warrants were outstanding to purchase an aggregate of 10,079 shares of Phone.com common stock at a weighted average exercise price of $8.43 per share.

Anti-takeover Provisions of Delaware Law and Charter Provisions

Phone.com is subject to the provisions of Section 203 of the Delaware Law. In general, the statute prohibits a publicly held Delaware corporation from engaging in a "business combination" with an "interested stockholder" for a period of three years after the date that the person became an interested stockholder unless, with exceptions, the business combination or the transaction in which the person became an interested stockholder is approved in a prescribed manner. Generally, a "business combination" includes a merger, asset or stock sale or other transaction resulting in a financial benefit to the stockholder, and an "interested stockholder" is a person who, together with affiliates and associates, owns, or within three years prior, did own, 15% or more of the corporation's outstanding voting stock. This provision may have the effect of delaying, deferring or preventing a change in control of Phone.com without further action by the stockholders. Phone.com's stock option and purchase plans generally provide for assumption of our plans or substitution of an equivalent option of a successor corporation or, alternatively, at the discretion of the board of directors, exercise of some or all of the options stock, including non-vested shares, or acceleration of vesting of shares issued pursuant to stock grants, upon a change of control or similar event. The board of directors has authority to issue up to 5,000,000 shares of preferred stock and to fix the rights, preferences, privileges and restrictions, including voting rights, of these shares without any further vote or action by the stockholders. The rights of the holders of the common stock will be subject to, and may be adversely affected by, the rights of the holders of any preferred stock that may be issued in the future. The issuance of preferred stock, while providing desirable flexibility in connection with possible acquisitions and other corporate purposes, could have the effect of making it more difficult for a third party to acquire a majority of our outstanding voting stock, thereby delaying, deferring or preventing a change in control of Phone.com. Furthermore, this preferred stock may have other rights, including economic rights senior to the common stock, and, as a result, the issuance of preferred stock could have a material adverse effect on the market value of the common stock. Phone.com has no present plan to issue shares of preferred stock.

169

COMPARISON OF RIGHTS OF HOLDERS
OF PHONE.COM COMMON STOCK AND
SOFTWARE.COM COMMON STOCK

Upon completion of the merger, holders of Software.com common stock will become entitled to receive Phone.com common stock. Both Phone.com and Software.com are companies formed under the laws of the State of Delaware.

The following is a summary of some material differences between the rights of holders of Software.com common stock and the holders of Phone.com common stock. These differences arise from differences between the Software.com second amended and restated certificate of incorporation and the Software.com by-laws, on the one hand, and the Phone.com amended and restated certificate of incorporation and the Phone.com by-laws, on the other hand. See "Description of Phone.com Capital Stock." This discussion is not a complete statement of all differences between rights of holders of Phone.com common stock and Software.com common stock. This summary discusses material differences the Software.com second amended and restated certificate of incorporation and by-laws and the Phone.com amended and restated certificate of incorporation and by-laws. This summary is qualified by the full text of each document. For information as to how to get those documents, see "Where You Can Find More Information" on page 175.

Size and Classification of the Board of Directors

Both the amended and restated certificate of incorporation of Phone.com and the second amended and restated certificate of incorporation of Software.com provide that the board of directors shall be divided into three classes of directors with staggered terms. The Phone.com by-laws provide that the board of directors shall consist of six members, whereas the Software.com by-laws provide that the board of directors shall consist of seven members.

Removal of Directors; Vacancies

The Phone.com amended and restated certificate of incorporation provides that stockholders may remove any director, with cause, upon an affirmative vote of the holders of a majority of the then-outstanding shares of voting stock, or, without cause, upon an affirmative vote of the holders of at least two-thirds ( 2/3) of the then-outstanding shares of voting stock. Any vacancy created by the removal of a director may be filled by an affirmative vote of a majority of the then outstanding voting stock or, in the absence of such an election, by an affirmative vote of a majority of the remaining directors then in office.

The second amended and restated certificate of incorporation of Software.com provides that stockholders may only remove a director with cause by an affirmative vote of the holders of a majority of the then-outstanding shares of voting stock. Any vacancy created by the removal of a director may only be filled by an affirmative vote of a majority of the remaining directors then in office.

Meetings of Stockholders

The by-laws of each of Phone.com and Software.com provide that a meeting of the stockholders shall be held each year at a time and place designated by the board of directors. The Phone.com by-laws provide that a special meeting may be convened at any time by the board of directors, the chairman of the board of directors, or the president of Phone.com. The Software.com by-laws provide that a special meeting may be convened at any time by the board of directors, the chairman of the board of directors, the president of Software.com, the chief executive officer of Software.com, or one or more stockholders holding shares in the aggregate entitled to cast not less than fifty-one percent (51%) of the votes at the special meeting. Hence, the proposed merger, if completed, will eliminate the authority to convene a special meeting of the chief executive officer of Software.com and any stockholder or stockholders holding shares entitled to cast at least fifty-one percent (51%) of the votes at such special meeting.

170

Indemnification of Officers and Directors

The by-laws of both Phone.com and Software.com provide for indemnification of directors, officers and employees to the fullest extent permitted by the General Corporation Law of Delaware. In addition, the by-laws of both Phone.com and Software.com provide that each company will pay any expenses incurred in defending any indemnified action, in advance, upon receipt of an undertaking by or on behalf of the indemnified party to repay such amount if it shall ultimately be determined that the indemnified party is not entitled to indemnification. However, the by-laws of Software.com contain a provision limiting the obligation of Software.com to pay such expenses in advance if a determination is made (i) by the board of directors of Software.com by a majority vote of a quorum consisting of directors who were not parties to the proceeding that resulting in the indemnification claim or (ii) if such quorum is not obtainable, by independent legal counsel in a written opinion, that the facts known to the decision-making party at the time such determination is made demonstrate that the indemnified party acted in bad faith or in a manner that such indemnified party did not believe was in the best interests of Software.com. The by-laws of Phone.com contain no such limitation on Phone.com's obligations to pay indemnification expenses in advance.

Annual Statement to Stockholders

The by-laws of Phone.com provide that the board of directors shall present at each annual meeting a full and clear statement of the business and condition of Phone.com. The by-laws of Software.com provide for no such obligation on the part of Software.com.

PROPOSALS TO PHONE.COM STOCKHOLDERS
TO BE VOTED ON AT THE PHONE.COM SPECIAL MEETING

The merger proposals

Proposal One--Issuance of shares of Phone.com common stock in the merger with Software.com

Phone.com's board of directors unanimously adopted a resolution approving the issuance of shares of Phone.com common stock, par value $0.001 per share, in the merger with Software.com, subject to completion of the merger. These shares will not be issued unless the merger is completed. This share issuance is being submitted for the approval of the stockholders of Phone.com pursuant to the requirements of the National Association of Securities Dealers applicable to companies with securities quoted on the Nasdaq National Market. The share issuance must be approved by the affirmative vote, in person or by proxy, of at least a majority of the votes properly cast at the Phone.com special meeting. The merger cannot be completed unless Phone.com stockholders approve the issuance of these shares in the merger and the amendment to Phone.com's amended and restated certificate of incorporation described in Proposal Two. These shares will be issued to Software.com stockholders in exchange for their Software.com common stock in a number per share of Software.com common stock equal to the exchange ratio described in this document. See "The Merger Agreement--The Exchange Ratio and Treatment of Software.com Securities."

The Phone.com board of directors unanimously recommends that Phone.com stockholders vote "FOR" the issuance of shares of Phone.com common stock in the merger.

Proposal Two--Amendment to amended and restated certificate of incorporation to change name

Phone.com's amended and restated certificate of incorporation, or certificate, provides that the name of Phone.com is "Phone.com, Inc." Pursuant to the merger agreement with Software.com, Phone.com has agreed to propose and recommend that the certificate be amended at the effective time to change Phone.com's name to " ." The Phone.com board of directors has authorized this amendment, subject to stockholder approval. Under the proposed amendment, subject to and upon consummation of the merger, Article I of the certificate would be amended and restated to read in its entirety as follows:

"The name of this corporation is (the "Corporation")."

171

The Phone.com stockholders are being asked to approve such amendment. The affirmative vote, in person or by proxy, of a majority of the shares of Phone.com common stock outstanding as of the Phone.com record date will be required to approve the amendment of the certificate. The effect of an abstention and a broker non-vote is the same as that of a vote against the proposal. The merger cannot be completed unless Phone.com stockholders approve the amendment of the certificate and the issuance of shares in the merger described in Proposal One above. In addition, the amendment of the certificate will not occur unless the stockholders approve Proposal One and the merger with Software.com is completed.

The Phone.com board of directors unanimously recommends that Phone.com stockholders vote "FOR" the amendment of the certificate to change the corporate name of Phone.com to subject to and contingent upon consummation of the merger.

The other proposal

Proposal Three--Amendment to certificate to increase authorized common stock

Phone.com's board of directors has approved an amendment to the certificate to increase the number of authorized shares of common stock from 250,000,000 shares to 1,000,000,000 shares, subject to stockholder approval. Under the amendment, Article IV Section (A) of the certificate would be amended and restated to read in its entirety as follows:

"(A) Classes of Stock. The Corporation is authorized to issue two classes of stock to be designated, respectively, "Common Stock" and "Preferred Stock." The total number of shares which the Corporation is authorized to issue is 1,005,000,000 shares, each with a par value of $0.001 per share. 1,000,000,000 of such shares shall be Common Stock, and 5,000,000 of such shares shall be Preferred Stock."

As of July 31, 2000, there were 250,000,000 shares of Phone.com common stock authorized, of which approximately 82,997,462 shares were issued and outstanding. In addition, approximately 27,700,417 shares of common stock were reserved for issuance under Phone.com's stock benefit plans. While the additional authorized stock is not required to complete the merger with Software.com, the issuance of Phone.com common stock to the stockholders, optionholders and warrantholders of Software.com pursuant to Proposal One will require at least 94,506,060 shares of Phone.com common stock. In addition, although Phone.com has no specific plans to use the additional authorized shares of Phone.com common stock other than as described above, the Phone.com board of directors believes that it is prudent to increase the number of authorized shares of Phone.com common stock to the proposed level in order to provide a reserve of shares available for issuances in connection with possible future actions. Such actions may include, but are not limited to, annual increases in the number of shares available for issuance pursuant to Phone.com's employee benefits plans, and stock splits or stock dividends if the Phone.com board of directors were to determine that such would be desirable to facilitate a broader base of stockholders.

The Phone.com board of directors also believes that the increased number of shares will provide the flexibility to effect other possible actions such as financings, corporate mergers, acquisitions of property, employee benefit plans and for other general corporate purposes. Having such additional authorized Phone.com common stock available for issuance in the future would allow the Phone.com board of directors to issue shares of Phone.com common stock without the delay and expense associated with seeking stockholder approval. Elimination of such delays and expense occasioned by the necessity of obtaining stockholder approval will better enable Phone.com, among other things, to engage in financing transactions and acquisitions as well as to take advantage of changing market and financial conditions on a more competitive basis as determined by the Phone.com board of directors. The Phone.com stockholders are being asked to approve such amendment.

The affirmative vote, in person or by proxy, of a majority of the shares of Phone.com common stock outstanding on the Phone.com record date will be required to approve the amendment of the certificate. The

172

effect of an abstention and broker non-vote is the same as that of a vote against the proposal. The increase in authorized Phone.com common stock will not have any immediate effect on the rights of existing stockholders. To the extent that the additional authorized shares are issued in the future, they will decrease the existing stockholders' percentage equity ownership and, depending on the price at which they are issued, could be dilutive to the existing stockholders.

The proposed amendment to increase the authorized number of shares of common stock could, under certain circumstances, have an anti-takeover effect, although this is not the intention of this proposal. For example, in the event of a hostile attempt to take over control of Phone.com, it may be possible for Phone.com to attempt to impede the attempt by issuing shares of the common stock, thereby diluting the voting power of the other outstanding shares and increasing the potential cost to acquire control of Phone.com. The amendment therefore may have the effect of discouraging unsolicited takeover attempts. By potentially discouraging initiation of any such unsolicited takeover attempt, the proposed amendment may limit the opportunity for Phone.com's stockholders to dispose of their shares at the higher price generally available in takeover attempts or that may be available under a merger proposal. The proposed amendment may have the effect of permitting Phone.com's management, including the board of directors, to retain its position, and place it in a better position to resist changes that stockholders may wish to make if they are dissatisfied with the conduct of Phone.com's business. However, the board of directors is not aware of any attempt to take control of Phone.com and the board of directors has not presented this proposal with the intent that it be utilized as a type of anti-takeover device.

The Phone.com board of directors unanimously recommends that Phone.com stockholders vote "FOR" the amendment of the certificate to increase the authorized Phone.com common stock to 1,000,000,000 shares.

LEGAL MATTERS

The validity of the shares of Phone.com common stock to be issued to Software.com stockholders pursuant to the merger will be passed upon by Skadden, Arps, Slate, Meagher & Flom LLP, special counsel to Phone.com. Certain tax matters will be passed upon by Wilson Sonsini Goodrich & Rosati, Professional Corporation, counsel to Software.com, and Skadden, Arps, Slate, Meagher & Flom LLP.

REPORT OF KPMG LLP, INDEPENDENT AUDITORS

The Board of Directors
Phone.com, Inc.:

We have audited the accompanying consolidated balance sheets of Phone.com, Inc. and subsidiaries as of June 30, 1999 and 2000, and the related consolidated statements of operations, stockholders' equity and comprehensive loss, and cash flows for each of the years in the three-year period ended June 30, 2000. In connection with our audits of the consolidated financial statements, we have also audited the financial statement schedule as listed in the index on page F-1. These consolidated financial statements and financial statement schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements and financial statement schedule based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Phone.com, Inc. and subsidiaries as of June 30, 1999 and 2000, and the results of their operations and their cash flows for each of the years in the three-year period ended June 30, 2000, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, the related financial statement schedule, when considered in relation to the consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

PHONE.COM, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
June 30, 1998, 1999, and 2000

1. Organization and Significant Accounting Policies

(a) Organization

Phone.com, Inc. (the Company) was incorporated in Delaware in 1994 to develop and market software that enables the delivery of Internet-based services to mass-market wireless telephones. The Company was formerly known as Unwired Planet, Inc., but changed its name to Phone.com, Inc. effective April 1999.

(b) Basis of Consolidation

The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.

(c) Revenue Recognition

Effective July 1, 1998, the Company adopted SOP 97-2, Software Revenue Recognition, as amended by SOP 98-4 and SOP 98-9. SOP 97-2, as amended, generally requires revenue earned on software arrangements involving multiple elements to be allocated to each element based on the relative fair value of the elements.

The Company licenses its UP.Link Server Suite and related server-based software products to network operators through its direct sales force and indirectly through its channel partners. The Company's license agreements do not provide for a right of return. Allowances for future estimated warranty costs are provided at the time revenue is recognized. Licenses can be purchased under a perpetual license model either on an as-deployed or on a prepaid basis, or alternatively, under a monthly or quarterly time-based license model under which no perpetual license is acquired. For licenses purchased on an as-deployed basis, license revenue is generally recognized quarterly as subscribers are activated to use the services that are based on the Company's UP.Link Server Suite and related server-based software products. For licenses purchased on a prepaid basis, prepaid license fees are recognized ratably over the period that maintenance and support services are expected to be provided unless the Company committed to provide the customer with future unspecified products under a subscription arrangement. Under a subscription arrangement, prepaid license fees are recognized ratably over the contractual term of the prepaid arrangement (i.e., the date the prepaid licenses expire if not used), generally 12 to 30 months, commencing at the beginning of the month delivery and acceptance occur by the network operator. The Company recognizes revenues from its other prepaid licenses, including the related maintenance and support services provided to network operators, ratably over the lesser of the estimated life of the software or the contractual term of the arrangement, generally 12 to 30 months, commencing at the beginning of the month delivery and acceptance occur by the network operator. For customers that license the Company's products under the time-based license model, revenues are recognized over the respective period based on the number of the customer's subscribers using the services that are based on the Company's products. Revenues from consulting services provided to network operators are recognized as the services are performed.

The Company recognizes revenues from UP.Browser agreements with wireless telephone manufacturers ratably over the period during which the services are performed, generally one year. The Company provides its wireless telephone manufacturer customers with support associated with their efforts to port its UP.Browser software to their wireless telephones, software error corrections, and new releases as they become commercially available.

(d) Cash and Cash Equivalents

Cash and cash equivalents consist of cash and highly liquid investments with remaining maturities of less than 90 days at the date of purchase. The Company is exposed to credit risk in the event of default by the

PHONE.COM, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

financial institutions or the issuers of these investments to the extent of the amounts recorded on the balance sheet in excess of amounts that are insured by the FDIC. As of June 30, 1999 and 2000, cash equivalents consisted principally of money market funds and commercial paper.

(e) Accounting for Certain Investments in Debt and Equity Securities

The Company classifies its investments in debt and equity securities as available-for-sale. Available-for-sale securities are carried at fair value with unrealized gains and losses recorded in accumulated other comprehensive income (loss) until realized.

(f) Financial Instruments and Concentration of Credit Risk

The carrying value of the Company's financial instruments, including cash and cash equivalents, short-term investments, accounts receivable, and equipment loans approximates fair value. Financial instruments that subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and trade accounts receivable.

The Company sells its products and services principally to leading wireless network operators and prominent wireless telephone manufacturers. Credit risk is concentrated in North America, Europe and Japan. The Company performs ongoing credit evaluations of its customers' financial condition and, generally, requires no collateral from its customers. The Company maintains allowances for estimated credit losses based on management's assessment of the likelihood of collection.

(g) Property and Equipment

Property and equipment are recorded at cost less accumulated depreciation and amortization. Depreciation is calculated using the straight-line method over the estimated useful lives of the respective assets, generally three to five years. Leasehold improvements are amortized over the shorter of the estimated useful lives of the assets or the lease term.

(h) Capitalized License Fees

The Company routinely enters into software license agreements which allow the Company to integrate software into its products up to a specified number of users. These licenses are amortized to cost of goods sold as products are sold up to a maximum period of 36 months, which is generally considered to be the maximum useful life of the software purchased.

(i) Impairment of Long-Lived Assets

The Company evaluates its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of any asset to future net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.

(j) Goodwill and Other Intangible Assets

The Company records goodwill when the cost of net identifiable assets it acquires exceeds their fair value. Goodwill and the cost of identified intangible assets are amortized on a straight-line basis over 3 years. The

Company regularly performs reviews to determine if the carrying value of assets is impaired. The purpose for the review is to identify any facts or circumstances, either internal or external, which indicate that the carrying value of the asset cannot be recovered. No such impairment has been indicated to date. If, in the future, management determines the existence of impairment indicators, the Company would use undiscounted cash flows to initially determine whether impairment should be recognized. If necessary, the Company would perform a subsequent calculation to measure the amount of the impairment loss based on the excess of the carrying value over the fair value of the impaired assets. If quoted market prices for the assets are not available, the fair value would be calculated using the present value of estimated expected future cash flows. The cash flow calculation would be based on management's best estimates, using appropriate assumptions and projections at the time.

(k) Research and Development

Research and development costs are expensed as incurred until technological feasibility has been established. To date, the Company's software has been available for general release concurrent with the establishment of technological feasibility and, accordingly, no development costs have been capitalized.

(l) Use of Estimates

The preparation of consolidated financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

(m) Income Taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be recovered.

(n) Accounting for Stock-Based Compensation Plans

The Company uses the intrinsic-value method to account for all of its employee stock-based compensation plans. Expense associated with stock-based compensation is being amortized on an accelerated basis over the vesting period of the individual award consistent with the method described in Financial Accounting Standards Board (FASB) Interpretation No. 28 (FIN 28).

(o) Foreign Currency Transactions

For foreign operations with the local currency as the functional currency, assets and liabilities are translated at year-end exchange rates, and statements of operations are translated at the average exchange rates during the year. Exchange gains or losses arising from translation of such foreign entity financial statements are included as a component of other comprehensive income (loss).

For foreign operations with the U.S. dollar as the functional currency, monetary assets and liabilities are remeasured at the year-end exchange rates as appropriate and non-monetary assets and liabilities are remeasured

at historical exchange rates. Statements of operations are remeasured at the average exchange rates during the year. Foreign currency transaction gains and losses are included in other income (expense), net, and to date, have not been material for any period presented.

(p) Comprehensive Income (Loss)

As of July 1, 1998, the Company adopted Statement of Financial Accounting Standards (SFAS) No. 130, Reporting Comprehensive Income. SFAS No. 130 establishes standards for the reporting and display of comprehensive net income (loss) and its components. However, it has no impact on the Company's net income as presented in the accompanying consolidated financial statements. The only items of comprehensive income (loss) that the Company currently reports are unrealized gains (losses) on marketable securities and foreign currency translation adjustments.

(q) Net Loss Per Share

Basic net loss per share is computed using the weighted-average number of outstanding shares of common stock excluding shares of restricted stock subject to repurchase summarized below. Diluted net loss per share is computed using the weighted-average number of shares of common stock outstanding and, when dilutive, potential shares of restricted common stock subject to repurchase, common stock from options, and warrants to purchase common stock using the treasury stock method and from convertible securities using the "as if converted" basis. The following potential shares of common stock have been excluded from the computation of diluted net loss per share for all periods presented because the effect would have been antidilutive (in thousands):

The weighted-average exercise price of stock options outstanding was $0.50, $3.18, and $42.47 as of June 30, 1998, 1999, and 2000, respectively. The weighted-average purchase price of restricted stock was $0.15, $0.30, and $0.48 as of June 30, 1998, 1999, and 2000, respectively. The weighted-average exercise price of warrants was $1.91, $1.91, and $8.43 as of June 30, 1998, 1999, and 2000, respectively. In June 1999, all outstanding shares of the Company's convertible preferred stock were automatically converted into common stock upon completion of the Company's initial public offering (see Note 4a).

(r) Recent Accounting Pronouncements

In June 1998, the FASB issued SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities, as amended by SFAS No. 137. SFAS No. 133 establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts (collectively referred to as derivatives) and for hedging activities. It requires that an entity recognize all derivatives as either assets or liabilities in the statement of financial position and measure those instruments at fair value. For a derivative not designated as a hedging instrument, changes in the fair value of the derivative are recognized in earnings in the period of change. The Company adopted SFAS No. 133 effective July 1, 2000. Management does not believe the adoption of SFAS No. 133 will have a material effect on the Company's consolidated financial position or results of operations.

In December 1999, the Securities and Exchange Commission (SEC) issued Staff Accounting Bulletin No. 101 (SAB 101), Revenue Recognition in Financial Statements, as amended by SAB 101A and SAB 101B,

F-12

PHONE.COM, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

which provides guidance on the recognition, presentation, and disclosure of revenue in financial statements filed with the SEC. SAB 101 outlines the basic criteria that must be met to recognize revenue and provides guidance for disclosure related to revenue recognition policies. In June 2000, the SEC issued SAB 101B that delayed the implementation of SAB 101. The Company must adopt SAB 101 no later than the fourth quarter of fiscal 2001. The SEC has recently indicated it intends to issue further guidance with respect to the adoption of specific issues addressed by SAB 101. Until such time as this additional guidance is issued, the Company is unable to assess the impact, if any, it may have on its financial position or results of operations.

In March 2000, the Emerging Issues Task Force (EITF) published their consensus on EITF Issue No. 00-2, Accounting for Web Site Development Costs, which requires that costs incurred during the development of web site applications and infrastructure, involving developing software to operate the web site, including graphics that affect the "look and feel" of the web page and all costs relating to software used to operate a web site should be accounted for under Statement of Position 98-1, Accounting for the Costs of Computer Software Developed or Obtained for Internal Use. However, if a plan exists or is being developed to market the software externally, the costs relating to the software should be accounted for pursuant to FASB Statement No. 86, Accounting for the Costs of Computer Software to Be Sold, Leased, or Otherwise Marketed. The Company will be required to adopt EITF Issue No. 00-2 in its first fiscal quarter, beginning after June 30, 2000. The Company is in the process of assessing any impact that the adoption of EITF Issue No. 00-2 will have on its consolidated financial position or results of operations.

In March 2000, the EITF published their consensus on EITF Issue No. 00-3, Application of AICPA Statement of Position 97-2, Software Revenue Recognition, to Arrangements That Include the Right to Use Software Stored on Another Entity's Hardware. EITF Issue No. 00-3 states that a software element covered by SOP 97-2 is only present in a hosting arrangement if the customer has the contractual right to take possession of the software at any time during the hosting period without significant penalty and it is feasible for the customer to either run the software on its own hardware or contract with another party unrelated to the vendor to host the software. The Company will be required to adopt EITF Issue No. 00-2 in its first fiscal quarter, beginning after June 30, 2000. Management does not believe the adoption of EITF Issue No. 00-3 will have a material effect on the Company's consolidated financial position or results of operations.

In March 2000, the FASB issued FIN 44, an interpretation of Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees. FIN 44 addresses inconsistencies in accounting for stock-based compensation that arise from implementation of APB Opinion No. 25. The Company does not anticipate that the adoption of FIN 44 will have a material effect on the Company's consolidated financial position or results of operations. The Company adopted FIN 44 effective July 1, 2000.

3. Equipment Loans

During the year ended June 30, 2000, the Company assumed seven separate secured promissory notes with a commercial lender in connection with its acquisitions. Under the terms of the acquisitions, the Company assumed approximately $1.6 million, of which approximately $1.4 million was outstanding as of June 30, 2000. The notes bear interest at an effective rate of 13.6% and expire in March 2003. The notes are secured by a Senior Loan and Security agreement with the commercial lender which grants the commercial lender a first security interest in the property and equipment that was purchased with the proceeds.

The loans mature over the next three years ending June 30, as follows :
2001--$388,000; 2002--$483,000; 2003--$555,000.

4. Stockholders' Equity

(a) Initial Public Offering

On June 11, 1999, the Company completed an initial public offering (IPO) of 9,200,000 shares of its common stock at a price of $8.00 per share and received net proceeds of approximately $66.8 million. At the IPO date, all outstanding shares of the Company's convertible preferred stock were automatically converted into common stock on a one-for-one basis.

(b) Secondary Offering

On November 16, 1999, the Company completed a secondary offering of 3,041,500 shares of its common stock at a price of $135.00 per share and received net proceeds of approximately $390.4 million.

(c) Reverse Stock Split

On June 7, 1999, the Company effected a two-for-three reverse stock split of its convertible preferred stock and common stock. The accompanying consolidated financial statements have been retroactively restated to give effect to this reverse stock split.

(d) Stock Split

On October 29, 1999, the Company effected a two-for-one stock split of its common stock. The accompanying consolidated financial statements have been retroactively restated to give effect to this stock split.

(e) Stock Plans

The Company is authorized to issue up to 18,767,774 shares of common stock in connection with its 1995 and 1996 stock option plans (the Plans) to directors, employees, and consultants. The Plans provide for the issuance of stock purchase rights, incentive stock options, or nonstatutory stock options.

The stock purchase rights are subject to a restricted stock purchase agreement whereby the Company has the right to repurchase the stock upon the voluntary or involuntary termination of the purchaser's employment with the Company at the original issuance cost. The Company's repurchase right lapses at a rate determined by the stock plan administrator, but at a minimum rate of 20% per year. Through June 30, 2000, the Company has issued 3,956,506 shares under restricted stock purchase agreements, of which 908,334 shares have been repurchased and 765,598 are subject to repurchase at a weighted-average price of $0.48 per share. Certain of these restricted shares were issued to officers of the Company for full recourse promissory notes with interest rates ranging from 5.49% to 6.48% and terms of four to five years.

Under the Plans, the exercise price for incentive stock options is at least 100% of the stock's fair value on the date of grant for employees owning less than 10% of the voting power of all classes of stock, and at least 110% of the fair value on the date of grant for employees owning more than 10% of the voting power of all classes of stock. For nonstatutory stock options, the exercise price is also at least 110% of the fair value on the date of grant for employees owning more than 10% of the voting power of all classes of stock and no less than 85% for employees owning less than 10% of the voting power of all classes of stock.

Under the Plans, options generally expire in 10 years. However, the term of the options may be limited to 5 years if the optionee owns stock representing more than 10% of the voting power of all classes of stock. Vesting periods are determined by the Company's Board of Directors and generally provide for shares to vest ratably over a 4- to 5-year period. As of June 30, 2000, there were -0- and 968,987 additional shares available for grant under the 1995 and 1996 stock option plans, respectively.

Company's outstanding common stock on the last day of the immediately preceding fiscal year.

Options granted under the Directors Plan vest immediately. The exercise price of the options granted under the Directors Plan is equal to the fair value of the Company's common stock on the date of grant.

On May 3, 2000, the Company adopted the 2000 Non-Executive Stock Option Plan (the Non-Executive Plan) and reserved a total of 2,000,000 shares of the Company's common stock for issuance thereunder. The plan provides for the issuance of nonstatutory stock options. Under the Non-Executive Plan, options expire in 10 years from the date of grant, and the options are available for issuance only to employees and consultants of the Company. Vesting periods are determined by the Company's Board of Directors and generally provide for shares to vest ratably over a 4-year period. As of June 30, 2000, there were 753,223 additional shares available for grant under the Non-Executive Plan.

(f) Stock-Based Compensation

The Company uses the intrinsic-value method in accounting for its employee stock-based compensation plans. Accordingly, no compensation cost has been recognized for any of its stock options granted or restricted stock sold because the exercise price of each option or purchase price of each share of restricted stock equaled or exceeded the fair value of the underlying common stock as of the grant date for each stock option or purchase date of each restricted stock share, except for stock options granted and restricted stock sold from October 1997 through March 1999. With respect to the stock options granted and restricted stock sold from October 1997 to March 1999, the Company recorded deferred stock compensation of approximately $2.4 million for the difference at the grant or issuance date between the exercise price of each stock option granted or purchase price of each restricted share sold and the fair value of the underlying common stock. This amount is being amortized on an accelerated basis over the vesting period, generally four to five years, consistent with the method described in FIN 28. During the year ended June 30, 2000, the Company recorded additional deferred stock compensation of approximately $8.0 million in conjunction with its acquisitions of APiON, Angelica and Velos (see Note 5). During the year ended June 30, 2000, the Company also recorded deferred stock-based compensation in the amount of $2.8 million for stock issued to an employee at below fair market value at the time of the grant, which is being amortized over the vesting period of 48 months consistent with the method described in FIN 28. Had compensation costs been determined in accordance with SFAS No. 123 Accounting for Stock-Based Compensation, for all of the Company's stock-based compensation plans, net loss and basic and diluted net loss per share would have been as follows (in thousands, except per share data):

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

the closing of the acquisition of APiON subject to forfeiture upon the occurrence of certain events. Current employees of APiON received approximately $2.5 million in cash with the remaining $5.1 million payable in common stock of the Company on each of the first two anniversaries of the closing of the acquisition of APiON contingent upon continued employment. The actual number of Phone.com shares to be issued to the then current and former employees of APiON will depend upon the fair value of Phone.com common stock on the distribution date. The total purchase price for the transaction including direct acquisition costs was approximately $246.8 million.

Common stock issued to former shareholders and cash paid to current and former employees of APiON at the closing of the acquisition was included in the purchase price. Contingent common stock issuable in the future to former employees of APiON has been treated as contingent consideration. The common stock that is issued to the former employees of APiON upon the satisfaction of certain future events will be added to goodwill and amortized over the remaining useful life. Common stock issuable in the future to current employees of APiON has been recorded as deferred stock-based compensation.

The Company accounted for the acquisition of APiON as a purchase with APiON's results of operations included from the acquisition date. The excess of the purchase price over the fair value of tangible net assets acquired amounted to approximately $244.5 million, with $242.5 million attributable to goodwill, $1.7 million attributable to assembled workforce, $170,000 attributable to developed technology and $110,000 attributable to in-process research and development. These assets are being amortized on a straight-line basis over a period of three years with the exception of the in-process research and development, which was expensed on the acquisition date. In connection with the acquisition, the Company recorded deferred stock-based compensation in the amount of approximately $5.1 million, which is being amortized on an accelerated basis over the vesting period of 24 months, consistent with the method described in FIN 28.

In addition, the Company also agreed to issue approximately 16,000 shares of its stock to employees of Angelica with an aggregate value of approximately $1.7 million, subject to certain forfeiture conditions dependent on continued employment. The Company accounted for the acquisition as a purchase with Angelica's results of operations included from the acquisition date. Approximately $2.0 million was allocated to goodwill, which is being amortized on a straight line basis over a period of three years. In addition, the Company recorded deferred stock-based compensation in the amount of $1.7 million, which is being amortized on an accelerated basis over the vesting period of 36 months, consistent with the method described in FIN 28.

These assets are being amortized on a straight-line basis over a period of three years. At the time of the acquisition, 12.1% of the shares issued by the Company were placed in escrow with most of the escrow shares to remain in escrow for a period of at least one year from the date of the acquisition to be released upon the occurrence of certain events.

F-21

PHONE.COM, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

whether there is an alternative future use for the technology. SFAS No. 86, sets guidelines for establishing technological feasibility. Technological feasibility can be achieved through the existence of either a detailed program design or a completed working model. As of the respective dates of the acquisitions of APiON, Paragon and Onebox discussed above, the Company concluded that the purchased in-process research and development had no alternative future use and expensed it according to the provisions of FASB Interpretation No. 4, Applicability of SFAS No. 2 to Business Combinations Accounted for by the Purchase Method.

The following table shows unaudited pro forma revenue, net loss and basic and diluted net loss per share of Phone.com, including APiON, AtMotion, Paragon, Onebox, and MyAble as if each company had been acquired as of July 1, 1998 (in thousands, except per share data):

The pro forma results are not necessarily indicative of what would have occurred if the acquisitions had been in effect for the periods presented. In addition, they are not intended to be a projection of future results and do not reflect any synergies that might be achieved from combined operations.

6. Leases

In March 2000, the Company entered into a lease for approximately 280,000 square feet of office space in Redwood City, California, that is under construction and is expected to be completed in the year 2001. Lease terms require a base rent of $3.25 per square foot per month as provided by the lease agreement and will increase by 3.5% annually on the anniversary of the initial month of the commencement of the lease. The lease is for a period of twelve years from the commencement date of the lease. The agreement required that the Company provide a letter of credit in the amount of $16.5 million. As of June 30, 2000, the Company has guaranteed the letter of credit and has pledged approximately $20.7 million, or 125% of the letter of credit, of cash equivalents and investments to be held in trust as security for the letter of credit. The restricted cash and investments held in trust under this agreement are earning approximately 6.7% interest and the resulting income earned is not subject to any restrictions. The lease further requires that the Company will pay the leasehold improvements which are expected to be at least $15 million over the next year.

The Company also entered into additional facility leases during the fiscal year ended June 30, 2000. One of the leases, which will expire on January 2003, was subsequently subleased through January 2001.

The Company's deferred tax liabilities resulted from its acquisitions during the year ended June 30, 2000, due to a difference in the financial statement and tax basis of net assets acquired.

In light of the Company's recent history of operating losses, the Company has recorded a valuation allowance for all of its deferred tax assets, except to the extent of deferred tax liabilities, as it is presently unable to conclude that it is more likely than not that the deferred tax assets in excess of deferred tax liabilities will be realized.

Approximately $49.2 million of the valuation allowance for deferred tax assets relating to net operating loss carryforwards is attributable to employee stock option deductions, the benefit from which will be allocated to additional paid-in capital when and if subsequently realized. The benefit from approximately $5.8 million of the total $7.5 million valuation allowance for the deferred tax asset related to research and development credit carryforwards will be allocated to additional paid-in capital when and if subsequently realized.

As of June 30, 2000, the Company had net operating loss carryforwards for federal and California income tax purposes of approximately $192 million and $96 million, respectively. In addition, the Company has federal and California research and development credit carryforwards of approximately $4.9 million and $3.9 million, respectively. The federal net operating loss carryforwards and research and development credit carryforwards will expire from 2011 through 2020 if not utilized. The California net operating loss carryforwards will expire from 2004 through 2006 if not utilized. The California research and development credit carryforwards can be carried forward indefinitely.

8. Geographic, Segment, Significant Customer Information and Enterprise Wide Reporting

During 1999, the Company adopted the provisions of SFAS No. 131, Disclosures about Segments of an Enterprise and Related Information. SFAS No. 131 establishes standards for the reporting by public business enterprises of information about operating segments, products and services, geographic areas, country-specific information and major customers. The method for determining what information to report is based on the way that management organizes the operating segments within the Company for making operational decisions and assessments of financial performance.

Revenues aggregating 37%, 43%, and 15% of total revenues for the years ended June 30, 1998, 1999, and 2000, respectively, were generated from customers who are also stockholders of the Company.

9. Litigation

In April 2000, the Company filed a lawsuit against Geoworks Corporation in the U.S. District Court in San Francisco, California, alleging and seeking a court order declaring that U.S. Patent No. 5,327,529, assigned to Geoworks, is not infringed by the Company and that the patent is also invalid and unenforceable. The Company took this action in response to Geoworks attempt to require industry participants to obtain licenses under the Geoworks patent. On June 15, 2000, Geoworks filed an answer to the Company's complaint and asserted a counterclaim against the Company alleging that the Company infringed the patent and seeking various forms of relief. The Company denies Geoworks' allegations and while it intends to pursue its position vigorously, the outcome of any litigation is uncertain, and the Company may not prevail. Additionally, the Company may incur substantial expenses in defending against this claim. Should the Company be found to infringe the Geoworks patent, it may be liable for potential monetary damages, and could be required to obtain a license from Geoworks. If the Company is unable to obtain a license on commercially reasonable terms, it may not be able to proceed with development and sale of some of its products.

10. Subsequent Events

On August 8, 2000, the Company entered into an agreement to merge with Software.com, Inc. (Software) in a transaction to be accounted for as a pooling of interests. Under the terms of the agreement, each issued and outstanding share of Software common stock will be exchanged for 1.6105 shares of Phone.com common stock. In addition, all outstanding stock options and warrants of Software will be exchanged for Phone.com stock options and warrants based on the exchange ratio. In connection with the merger, the Company and Software.com expect to incur one-time expenses of approximately $100.0 million.

On August 8, 2000, the Company adopted a Stockholder Rights Agreement (the Rights Agreement). The Rights Agreement is designed to protect the long-term value of the Company for its stockholders during any future unsolicited acquisition attempt. In connection with the Rights Agreement, the Company declared a dividend of one right for each share of the Company's common stock outstanding on August 18, 2000.

On August 11, 2000, the Company made a cash payment of $17.0 million to a former shareholder of Paragon that was originally due one year from the original purchase date of March 4, 2000 (See Note 5). The payment was made in conjunction with the former shareholder's separation from the Company.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Information at June 30, 2000 and for the six months ended June 30, 2000 and 1999 is unaudited)

1. Summary of Significant Accounting Policies

Organization and Business

Software.com (the Company) develops, markets, sells, and supports a variety of Internet infrastructure applications to service providers worldwide, including telecommunications companies, Internet Service Providers, application service providers, cable-based Internet access providers, wireless telephony carriers, Internet portals, competitive local exchange carriers, and Internet service wholesalers. Service providers use these products to provide advanced messaging offerings, such as Internet mail services, to their consumer and business customers.

Principles of Consolidation and Basis of Presentation

The consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany balances and transactions have been eliminated.

As further described in Note 11, the Company acquired AtMobile.com, Inc. (AtMobile) on April 11, 2000. The acquisition was accounted for as a pooling of interests. Accordingly, the financial information presented reflects the combined financial position and operations of the Company and AtMobile for all dates and periods presented.

Interim Financial Statements

The accompanying balance sheet as of June 30, 2000, and the statements of operations and cash flows for the six months ended June 30, 1999 and 2000, and the statement of stockholders' equity for the six months ended June 30, 2000, are unaudited. Certain information and footnote disclosures normally included in the financial statements have been condensed or omitted. In the opinion of management, the unaudited financial statements have been prepared on the same basis as the audited financial statements and include all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of the financial position, results of operations, and cash flows for the interim periods. The results of operation for the six months ended June 30, 2000, are not necessarily indicative of operating results to be expected for the full fiscal year.

Cash and Cash Equivalents

The Company considers cash equivalents to be only those investments, which are highly liquid, readily convertible to cash and which mature within three months from date of purchase. Cash and cash equivalents include commercial paper, money market accounts, debt securities and auction rate securities at December 31, 1999 and 1998.

Marketable Securities

Marketable securities consist of investments in commercial paper, government securities, corporate notes and certificates of deposit that have maturities greater than three months but less than one year from date of purchase.

The Company considers its investment portfolio available-for-sale as defined in Statement of Financial Accounting Standards No. 115, "Accounting for Certain Investments in Debt and Equity Securities," issued by the Financial Accounting Standards Board (FASB). Accordingly, these investments are recorded at fair value. Unrealized losses for the year ended December 31, 1999, were $6,000 and have been recorded as comprehensive

income (loss). There were no material unrealized gains or losses nor any material differences between the estimated fair values and costs of securities at December 31, 1997 and 1998. There were no material realized gains and losses for the years ended December 31, 1997, 1998 and 1999. The cost of securities sold is based on the specific identification method.

The fair value of available-for-sale marketable securities by type of security are as follows (in thousands):

Concentration of Credit Risk, Other Risks and Significant Customers

The Company's business is extremely competitive and is characterized by rapid technology change, new product development and product obsolescence, and evolving industry standards.

The Company grants credit terms in the normal course of business to its customers. The Company does not require collateral; however, it does perform periodic credit evaluations and analysis of the amounts due from its customers. Credit losses have been within management's expectations and potential uncollectible accounts have been provided for in the financial statements.

There were no customers that accounted for greater than 10% of total revenues for the year ended December 31, 1999. Revenues from the Company's two largest customers in each of the years ended December 31, 1997 and 1998, accounted for and 17% and 11% and 12% and 9% of total revenues, respectively. At December 31, 1998 and 1999, accounts receivable from one and two customers, respectively, was 25% and 16% of total accounts receivable.

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation. Maintenance and repairs are charged to expense as incurred. Expenditures for additions and major improvements are capitalized.

Depreciation and amortization are computed on a straight-line basis over the following estimated useful lives:

Computer equipment and
 software...............                                      3 to 5 years
Furniture and fixtures..                                           7 years
Leasehold improvements..  Lesser of estimated useful life or life of lease

Goodwill and Intangible Assets

Goodwill recognized in business combinations accounted for as a purchase is being amortized on a straight-line basis over five years. Goodwill amortization expense was $100,000 for the year ended December 31, 1999.

SOFTWARE.COM, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

(Information at June 30, 2000 and for the six months ended June 30, 2000 and 1999 is unaudited)

Intangible assets resulting from business combinations consists of core/alternative use technology, a covenant not to compete and assembled workforce, and are being amortized on a straight-line basis over three to five years. Patent and trademark costs are amortized using the straight-line method over periods ranging from 5 to 15 years. Intangible asset amortization expense was $1,000, $2,000 and $231,000 for the years ended December 31, 1997, 1998 and 1999, respectively.

Long-Lived Assets

The Company assesses on an ongoing basis the recoverability of long-lived assets, including goodwill and other intangible assets, based on estimates of future undiscounted cash flows for the applicable business compared to net book value. If the future undiscounted cash flows estimate were less than net book value, net book value would then be reduced to fair value based on an estimate of discounted cash flows. The Company also evaluates the amortization periods of all assets to determine whether events or circumstances warrant revised estimates of useful lives.

Income Taxes

Income taxes are accounted for using the liability method in accordance with Statement of Financial Accounting Standards No. 109, "Accounting for Income Taxes," issued by the FASB (see Note 6). Under this method, deferred tax liabilities and assets are recognized for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. A valuation allowance is recorded on the Company's deferred tax assets until such time that it is more likely than not that the deferred tax assets will be realized.

Accounting for Stock-Based Compensation

Employee stock options are accounted for under Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees," which requires the recognition of expense when the option price is less than the fair value of the stock at the date of grant.

The Company generally awards options for a fixed number of shares at an option price equal to the fair value at the date of grant. The Company has adopted the disclosure-only provisions of FASB's Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based Compensation" (FAS 123).

The Company accounts for stock issued to nonemployees in accordance with the provisions of SFAS No. 123 and the Emerging Issues Task Force consensus in Issue No. 96-18, "Accounting for Equity Instruments that are Issued to other than Employees for Acquiring, or in Conjunction with Selling Goods or Services."

Other Comprehensive Income (Loss)

In June 1997, the FASB issued Statement of Financial Accounting Standards No. 130, "Reporting Comprehensive Income" (FAS 130). Under FAS 130, the Company is required to report unrealized gains (losses) on its marketable securities and any other foreign currency translation adjustments within other comprehensive income (loss). In 1999, other comprehensive loss consists of unrealized gains (losses) on marketable securities.

Revenue Recognition

In October 1997, the American Institute of Certified Public Accountants issued Statement of Position 97-2 (SOP 97-2), which was amended by SOP 98-4 and SOP 98-9, "Software Revenue Recognition." These

statements provide guidance on applying generally accepted accounting principles in recognizing revenue on software transactions. This guidance is effective for the Company's transactions entered into subsequent to January 1, 1998. The application of certain provisions was deferred until fiscal years beginning on or after March 15, 1999. Final adoption of these provisions is not expected to have a material impact on the Company's financial condition or results of operation.

Revenue from Software Licenses. The Company recognizes revenue from sales of software upon delivery of a license key to the customer, provided that persuasive evidence of an arrangement exists, the license fee is fixed and determinable, and collection of the fee is considered probable. If the license agreement has a multi-year term, as is typical with an InterMail Mix contract, or the license fees are calculated based on variable measures, such as the number of mailboxes in use, the Company recognizes revenue as the customer activates mailboxes on their system. When the Company enters into a contract where a customer may activate up to a specified number of mailboxes and support and maintenance fees are based on that specified number, the Company recognizes revenue evenly and ratably as payments become due over the term of the arrangement. When the Company enters into license agreements under which revenues are based on a percentage of our customer's revenues, the Company recognizes revenue as earned and reported by the customer. To date, revenues and expenses related to these revenue-sharing arrangements have not been significant. Revenues from sales to significant resellers are not recognized until the end user has been identified and the license key is issued.

Revenue from Services. Support and maintenance contracts generally call for the Company to provide technical support and software updates and upgrades to customers. Support and maintenance revenue is recognized ratably over the support or maintenance period.

The Company recognizes revenue, contract costs, and profit on management and consulting contracts in accordance with Statement of Position No. 81-1 (SOP No. 81-1), "Accounting for Performance of Construction-Type and Certain Production-Type Contracts." Consulting services revenues are primarily related to deployment services performed on a time-and-materials basis under separate service arrangements. Revenue, contact costs, and profit on contracts on fixed-fee contracts are recognized on the percentage-of-completion method (determined based on the cost-to-cost method). Revenue, contract costs, and profits on time-and-material contracts are recorded based upon direct labor hours at fixed hourly rates and cost of materials as incurred. When the current estimates of total contract revenue and contract cost indicate a loss, a provision for the entire loss on the contract is recorded. Revisions to contract estimates are recorded as the estimating factors are refined. The effect of these revisions is included in income in the period the revisions are made.

When software and services are billed prior to the time the related revenue is recognized under the foregoing policy, deferred revenue is recorded. There were no unbilled accounts receivable at December 31, 1998 and 1999.

Research and Development

Pursuant to Statement of Financial Accounting Standards No. 86, "Accounting for the Costs of Computer Software to be Sold, Leased, or Otherwise Marketed," development costs related to software products are expensed as incurred until the "technological feasibility" of the product has been established. Because of the relatively short time period between "technological feasibility" and product release, and the insignificant amount of costs incurred during such period, no software development costs have been capitalized.

Advertising Costs

The Company expenses advertising costs as incurred. Advertising expense totaled $553,000, $499,000 and $732,000 for 1997, 1998 and 1999, respectively.

Net Loss Per Share

Basic and diluted net loss per common share are presented in conformity with Statement of Financial Accounting Standards No. 128, "Earnings Per Share" (FAS 128), for all periods presented. In accordance with FAS 128, basic and diluted net loss per share has been computed using the weighted-average number of shares of common stock outstanding during the period.

For the year ended December 31, 1999, options to purchase 239,400 shares with exercise prices greater than the average market prices of common stock were outstanding.

In accordance with FAS 128, basic and diluted net loss per share has been computed using the weighted-average number of shares of common stock outstanding during the period. The Company has excluded all redeemable convertible preferred stock, convertible preferred stock, warrants and outstanding stock options from the calculation of diluted loss per share because all such securities are antidilutive for all periods presented.

Segment Information

In June 1997, the FASB issued Statement of Financial Accounting Standards No. 131, "Disclosures about Segments of an Enterprise and Related Information" (FAS 131). This statement establishes standards for the way companies report information about operating segments in annual financial statements. It also establishes standards for related disclosures about products and services, geographic areas and major customers, presented in Notes 1 and 9. Based on the provisions of FAS 131 and the manner in which management analyzes its business, the Company has determined that it does not have separately reportable operating segments.

Fair Value of Financial Instruments

The carrying amounts reported in the balance sheets for cash and cash equivalents, marketable securities, accounts receivable and accounts payable approximate their fair values due to the short-term nature of these financial instruments. The carrying values of the note payable to bank and the long-term debt outstanding as of December 31, 1998, approximate their fair values. The fair values of these instruments were estimated based on current interest rates available to the Company for debt instruments with similar terms, degrees of risk and remaining maturities.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ materially from those estimates.

Reclassifications

Certain prior year amounts were reclassified to conform with current year financial statement presentation.

2. Acquisitions

In April 1999, the Company completed its acquisition of Mobility.Net, Inc. (Mobility.Net), which offers products for Web messaging using a Java-based technology platform that complement the Company's product offerings. The Company issued 1,579,000 shares of its common stock in exchange for all of the outstanding shares of Mobility.Net. The acquisition was accounted for as a pooling of interests. Accordingly, the financial

information presented reflects the combined financial position and operations of the Company and Mobility.Net for all dates and periods presented.

In October 1999, the Company completed its acquisition of Telarc, Inc.
(Telarc), which currently provides carrier-scale Short Messaging Service (SMS)
technologies that complement the Company's product offerings. In exchange for all of the issued and outstanding stock of Telarc, the Company issued 212,000 shares of the Company's common stock with a value of $10.0 million and $1.5 million in cash. The acquisition of Telarc was accounted for as a purchase and, accordingly, the acquired assets and liabilities were recorded at their estimated fair values at the date of acquisition. Telarc's operating results have been included in the Company's consolidated financial statements results from the acquisition date of October 20, 1999. The purchase price plus costs directly attributable to the completion of the acquisition of approximately $101,000 have been allocated to the assets and liabilities acquired based on their approximate fair value as determined through an independent appraisal using proven valuation procedures and techniques. The purchase price of $11.6 million was allocated as follows (in thousands):

Tangible assets.................................................. $   263
Developed technology.............................................   5,700
Assembled workforce and other intangibles........................     125
In-process research and development..............................   3,210
Goodwill.........................................................   2,303
                                                                  -------
  Total purchase price........................................... $11,601
                                                                  =======

The appraisal of the acquired business included $3.2 million of in-process research and development, which was primarily related to three products under development. The valuation represents the five-year after tax cash flow of the in-process technology using a discount rate of 40%. This acquired technology had not yet reached technological feasibility and had no future alternative uses. Accordingly, it was written off at the time of the acquisition. Goodwill and identified intangibles are being amortized on a straight-line basis over their estimated economic useful lives of three to five years. The pro-forma effect of the Telarc acquisition as if it has occurred on January 1, 1998 and 1999, is not significant to the financial statements presented herein.

In addition, in conjunction with the Company's acquisition of Telarc, the Company entered into an employment agreement with an executive of Telarc which the Company will pay a total of $3.5 million in cash to be paid out and expensed in equal quarterly installments over ten quarters beginning March 2000.

4. Note Payable to Bank, Long-Term Debt and Credit Facilities

The Company had an arrangement with a financial institution which provided for a total line of credit not to exceed the lesser of $15.0 million (of which the Company could draw down up to $2.5 million as an equipment acquisition loan), or an amount based on certain receivables collection criteria (the Software.com. credit facility). As of December 31, 1999, the Company had repaid all borrowings using proceeds of the initial public offering of its common stock in June 1999, and has terminated this arrangement. At December 31, 1998, borrowings under the line of credit totaled $7,395,000. The interest rate for borrowing under the line of credit was prime rate plus 1.5% (9.25% at December 31, 1998).

The Company also had a $2 million revolving line of credit with a bank (the AtMobile line of credit). Borrowings outstanding under this line of credit were $150,000 at December 31, 1998. The line of credit was secured by substantially all accounts receivable. The line of credit was refinanced on April 30, 1999, with a term loan from the bank.

Long-term debt consists of the following (in thousands):

In connection with a renegotiation of the Software.com credit facility in 1998, the Company issued a warrant to the financial institution to purchase 68,000 shares of common stock of the Company at an exercise price of $5.15 per share. The fair value of the warrants was determined to be approximately $94,000, using the Black-Scholes option pricing model with an expected volatility factor of 35%, risk-free interest rate of 6%, no dividend yield, and a 5 year life, and was amortized as interest expense over the term of the credit facility agreement.

Each share of AtMobile preferred stock was convertible into one share of AtMobile common stock.

During June 1999, in connection with the issuance of the Series B AtMobile preferred stock, the board of directors of AtMobile declared a 2.19769223-to-1 stock split on the Series A AtMobile preferred stock. The effect of the split was to increase the number of authorized, issued and outstanding shares of Series A AtMobile preferred stock. The number of shares issued and outstanding has been retroactively adjusted to reflect these changes.

Prior to the conversion of all outstanding Software.com preferred stock into common stock upon completion of the Company's initial public offering, the Series A Software.com Preferred Stock redemption price included a redemption premium of 10% per year compounded annually. Accordingly, the initial fair value of the Software.com Preferred Stock A was increased by periodic accretions, using the interest method, so that the carrying amount would equal the mandatory redemption amount at the redemption date. For the years ended December 31, 1997, 1998 and 1999, such periodic accretions totaled $730,000, $825,000 and $403,000, respectively, and are reflected as charges against the Company's accumulated deficit for each year.

Warrants and Options

In connection with the issuance of the Software.com Series A Preferred stock, the Company also issued a warrant to purchase 529,101 shares of common stock of the Company at an exercise price of $5.00 per share and a warrant to purchase 279,841 shares of common stock at an exercise price of $7.00 per share (the Common Stock Purchase Warrants). The warrants were exercisable for a period of five years from the date of issuance. At issuance, the fair value of the warrants, approximately $430,000, was recorded as common stock on the Company's balance sheet. The fair value of the warrants was determined using the Black-Scholes option pricing model using an expected volatility factor of 30%, risk free interest rate of 6%, no dividend yield, and a 5-year life. In November 1999, the warrant holders exercised the warrants, which resulted in the issuance of 753,379 shares of common stock.

In July 1998, the Company executed an agreement with the holders of the Software.com Preferred Stock A (the Waiver of Redemption Rights Agreement) whereby the holders of such shares agreed to extend the redemption date of the Series A Preferred Stock for a period of 15 months to January 3, 2000. In consideration of the Waiver of Redemption Rights Agreement, the Company executed an amendment to the Common Stock Purchase warrants, which reduced the exercise price of such warrants to $4.15 per share. The exercise period of the warrants remained unchanged. As a result of the change in the exercise price, the fair value of the warrants increased by approximately $294,000, which was reclassified from redeemable convertible preferred stock into common stock.

During 1998, the Company issued warrants to purchase shares of AtMobile Series A preferred stock in connection with a capital lease financing arrangement. In accordance with the warrant agreement, the number of shares originally issuable and the related exercise price were adjusted based on a subsequent AtMobile Series B preferred financing in June 1999 whereby the warrants were for 6,395 shares of AtMobile Series A preferred stock with an exercise price of $7.04 per share. The warrants were exercised in connection with the Software.com and AtMobile business combination (see Note 11) and the AtMobile preferred shares were converted into 6,395 shares of Software.com common stock. The Company estimated the value of the warrants to be approximately $3.95 per share, based on a Black-Scholes valuation model, and recorded corresponding deferred debt issuance costs which are being amortized over the life of the related capital lease.

In July 1999, in connection with a bank financing agreement, the Company issued warrants to a bank to purchase up to 20,370 shares of AtMobile Series B preferred stock at a per share purchase price of $7.04. The warrants were exercised in connection with the Software.com and AtMobile business combination (see Note 11) and the AtMobile preferred shares were converted into 20,370 shares of Software.com common stock. The Company estimated the value of the warrants to be approximately $4.64 per share, based on a Black- Scholes valuation model, and recorded corresponding deferred debt issuance costs which are being amortized over the term of the related financing agreement.

Amortization of debt issuance cost was $6,250, $29,331, and $13,276 in 1998, 1999, and for the six months ended June 30, 2000, respectively.

As part of the placement fee associated with the AtMobile Series D capital placement and the bridge financing in March and February 2000, the Company issued a warrant to purchase 6,640 shares of AtMobile Series D Preferred Stock at $26.80 per share. The warrant expires in 2005. The Company estimated the value to be approximately $6.87 per share, based on the Black-Scholes valuation model.

The AtMobile Preferred Series A, Series B, and Series D warrants were valued using the Black-Scholes valuation model based upon the exercise prices described above, a risk free rate of 6%, a dividend yield of 0%, volatility of .6 and an expected life of 1-7 years.

In June 1999, AtMobile entered into a web development, hosting, maintenance, and licensing agreement with a contractor. As part of the agreement, AtMobile issued warrants to the contractor to purchase 75,944 shares of common stock with an exercise price of $0.17 per share in exchange for these services. The warrants expire June 2009. The warrants become exercisable based on the achievement of certain milestones or over the period for which the services are performed through June 2002, as prescribed in the agreement. During both 1999 and the six months ended June 30, 2000, warrants for 20,938 shares became exercisable for the services performed by the contractor. The value of the services performed was determined based upon the underlying value of the exercisable warrants. During 1999 and the six months ended June 30, 2000, the Company recorded stock based compensation-acquisition related costs related to these services of $100,732 and $2,372,593, respectively.

In July 1999, the Company obtained bridge financing in the form of a convertible promissory note of $350,000 from a stockholder. In connection with that financing the Company issued a warrant to the stockholder to purchase 4,974 shares of common stock at $0.69 per share. The warrant expires in 2004. The Company estimated the value of the warrant to be approximately $0.34 per share and recorded corresponding interest expense of $1,710 related to the warrant in 1999.

In November 1999, the Company entered into a development agreement with a contractor. As part of the agreement, the Company issued warrants to the contractor to purchase 12,466 shares of common stock, with an exercise price of $0.69 per share in exchange for these services. The warrants expire November 2004. The warrants become exercisable once certain performance milestones are achieved, as prescribed in the agreement. During 1999 and the three months ended March 31, 2000, warrants for 4,155 and 6,233 shares, respectively, became exercisable for the services performed by the contractor. The remaining unexercisable warrants as of March 31, 2000 were cancelled as the Company elected, as provided for in the agreement, not to pursue the attainment of the remaining milestones. The value of the services performed was based upon the underlying value of the exercisable warrants. During 1999 and the six months ended June 30, 2000, the Company recorded cost related to these services of $18,563 and $585,464, respectively.

Due to the uncertainty surrounding the timing of realizing the benefits of its favorable tax attributes in future tax returns, the Company has placed a valuation allowance against its otherwise recognizable deferred tax assets.

At December 31, 1999, the Company had net operating loss carryforwards available to reduce future federal and state income of $40.9 million and $11.1 million, respectively, which expire from 2011 to 2019 for federal and 2002 to 2004 for state.

The Company has federal and state research and development credits of approximately $861,000 and $188,000, respectively, expiring in 2011 to 2014, which may be used to offset future tax liabilities. The Company also has foreign tax credits of approximately $484,000, which will expire in the years 2003 to 2004.

Under Section 382 of the Internal Revenue Code, the utilization of the net operating loss and tax credit carryforwards (including those related to the operations of AtMobile) may be limited based on changes in the percentage of ownership of the Company.

Included in the valuation allowance balance is $5.8 million related to the exercise of stock options which is not reflected as an expense for financial reporting purposes. Accordingly, any future reduction in the valuation allowance relating to this amount will be recorded in equity and not reflected as an income tax benefit in the statement of operations.

No provision has been made for federal, state, or additional foreign income taxes related to approximately $506,000 of undistributed earnings of foreign subsidiaries, which have been or are intended to be permanently reinvested.

7. Commitments and Contingencies

The Company leases computer equipment, computer software, and office equipment under capital lease agreements expiring in 2002. The Company also leases its office space and other equipment under noncancelable

Rent expense totaled $988,000, $1,607,000 and $2,403,000 for the years ended December 31, 1997, 1998 and 1999, respectively.

The Company leases one of its facilities from a related party (see Note 10). The lease expires in February 2002.

The Company was involved in a contract dispute with a third-party technology partner under a 1996 licensing agreement. The dispute related to a minimum royalty obligation of $1,000,000 purportedly owed by the Company to the third party. In 1997, the Company accrued $1,000,000 for its potential exposure under the claim. In February 1999, the parties entered into an agreement to settle all outstanding claims. The Company paid the third party $400,000, and as a result the related accrual was reduced to $600,000 at December 31, 1998, to reflect the complete resolution of this matter.

8. Employee Stock Option, Stock Purchase and Defined Contribution Plans

Employee Stock Option Plans

In October 1995, the Company adopted a stock option plan (the 1995 Plan) that provides for the issuance of incentive and nonqualified stock options. Options under the 1995 Plan are granted for a term of five and ten years at an exercise price equal to the fair market value of the shares at the date of grant, as determined by the board of directors. The options generally vest over a period of four years at 25% per year. The 1995 Plan authorizes a total of up to 10,500,000 shares of Common Stock for issuances as either incentive stock or nonqualified options. At December 31, 1999, 362,000 shares remain available for grant under this plan.

In addition to the options granted under the 1995 Plan, the Company has granted options outside of the 1995 Plan to purchase an aggregate of 1,074,000 shares of common stock. These options contain the same vesting provisions as those granted under the 1995 Plan except that an option to purchase 250,000 shares is subject to accelerated vesting in certain circumstances. At December 31, 1999, 38,000 shares remained authorized and available for grant.

Subsequent to year end, in January 2000, the Company adopted a stock option plan (the 2000 Plan) that provides for the issuance of nonqualified stock options. Options under the 2000 Plan are granted for a term of ten years at an exercise price equal to the fair market value of the shares at the date of grant, as determined by the board of directors. The options generally vest over a period of four years at 25% per year. The 2000 Plan authorizes a total of up to 750,000 shares of common stock for issuances as nonqualified options.

The Amended and Restated AtMobile 1997 Stock Option Plan (the AtMobile Plan) provided for the granting of nonqualified and incentive stock options to officers, directors, employees, and consultants.

Stock options granted under the AtMobile Plan typically vest over a four- year period and expire ten years from the date of grant. Vested incentive stock options are exercisable during continued employment or generally within 90 days of terminating employment. Vested nonqualified stock options are exercisable until expiration. All stock options issued and outstanding under the AtMobile Plan were converted into Software.com common stock options in connection with the business combination (see Note 11) using the exchange ratio used to effect the combination. All disclosures related to stock options issued under the AtMobile Plan have been adjusted to give effect to the conversion ratio.

In October and December 1999, the Company issued stock options under the AtMobile Plan to consultants to acquire 13,433 shares of common stock at an exercise price of $0.69 per share, which expire in December 2009. Of these options, 1,793 shares were vested on the date of grant. The remaining 11,640 shares vest over four years. The Company recognized stock-based compensation expense of $924 and $462,000 related to these stock options in 1999, and the six months ended June 30, 2000, respectively.

A summary of the stock option activity is as follows (in thousands, except per share amounts):

Prior to the Company's initial public offering in June 1999, the fair value of each Software.com option grant was determined on the date of the grant using the minimum value method. Subsequent to the offering, the fair value of Software.com options was determined using the Black-Scholes method. The fair value of each AtMobile option was determined on the date of grant using the minimum value method. The weighted average fair value of an option granted during 1997, 1998 and 1999 was $.64, $.64 and $7.71, respectively. Except for the volatility assumption, which was only used under the Black-Scholes method, the following assumptions were used for 1997, 1998 and 1999, respectively, to perform the calculations: risk-free interest rate of 6%, 6% and 5.8%, a weighted-average expected life of the options of 3.4, 3.3 and 4.3 years, 90% volatility in 1999 only and no assumed dividend yield for all years.

If the Company recognized employee stock option-related compensation expense in accordance with FAS 123 and used the minimum value method for 1997 and 1998 and the combined Black-Scholes and minimum value methods for 1999 for determining the weighted average fair value of options granted, the Company's pro forma net loss applicable to common stockholders would have been $12,749,000, $16,367,000 and $20,083,000, respectively. The 1997, 1998 and 1999 pro forma basic and diluted loss per share would have been $0.46, $0.57 and $0.56.

For purposes of pro forma disclosures, the estimated fair value of the options is amortized over the options' vesting periods. The pro forma effect on net loss for 1997, 1998 and 1999 is not representative of the pro forma effect on net income or loss in future years because compensation expense in future years will reflect the amortization of a larger number of stock options granted in several succeeding years.

As of December 31, 1999, the Company's stock options had a weighted-average remaining contractual life of 5.24 years.

In connection with the grant of certain share options to employees during 1998 and 1999, the Company recorded deferred compensation of approximately $1,495,000 and $770,000, respectively, for the aggregate differences between the exercise prices of options at their dates of grant and the deemed fair value for accounting purposes of the common shares subject to such options. Such amounts are being amortized over the vesting period of the related options. Amortization expense recognized for the years ended December 31, 1998 and 1999, totaled $48,000 and $544,000, respectively.

Employee Stock Purchase Plan

In May 1999, the Company adopted an employee stock purchase plan (the ESPP). A total of 1,000,000 shares of common stock have been reserved for issuance under the ESPP. The number of common shares

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

(Information at June 30, 2000 and for the six months ended June 30, 2000 and 1999 is unaudited)

reserved under the ESPP may be increased annually on July 1 of each year beginning in 2000. Such increases are limited to the lesser of 500,000 shares or 2% of the shares outstanding on that date or can be further limited by the board of directors.

The ESPP, which is intended to qualify under Section 423 of the Internal Revenue Code, contains four six-month purchase periods within twenty-four month offering periods. The offering periods generally start on the first trading day on or after May 1 and November 1 of each year. Eligible participants may purchase common stock through payroll deductions of up to 15% of each participant's compensation. The maximum number of shares a participant may purchase is 10,000 shares. Amounts deducted and accumulated by the participant are used to purchase common shares at the end of each purchase period. The price of stock purchased under the ESPP is 85% of the lower of the fair market value of the common stock at the beginning of the offering period and the end of each purchase period. The ESPP will terminate in 2009.

For the year ended December 31, 1999, employees purchased 75,948 shares at $12.75. At December 31, 1999, 924,000 shares remained available for future issuance under the Purchase Plan.

Defined Contribution Plan

The Company maintains a defined contribution 401(k) plan under which its employees are eligible to participate. Participants may make, within certain limitations, voluntary contributions based upon a percentage of their compensation. The Company may make voluntary contributions to the Plan. Participants are fully vested in the Company's contributions after a specified number of years of service, as defined under the plan. No Company contributions have been made to date under the plan.

WAP BUSINESS OF APiON

NOTES TO THE FINANCIAL STATEMENTS

1. Description of business

APiON was incorporated in the United Kingdom in May 1995 to provide computer software consulting services. Its WAP business was established in May 1998 to develop wireless Internet products for sale to world wide telecommunications service providers.

2. Accounting policies

Basis of Presentation

The activities referred to above were carried out jointly by APiON Limited and by its related company, incorporated in the Republic of Ireland, APiON Telecoms Limited (jointly referred to as "APiON").

The operations of APiON consisted of the WAP business ("WAP"), and other trading activities (the "Services business"). In conjunction with the acquisition of WAP the trading activities associated with the Services business have been spun off to the common shareholders of APiON. Please refer to the Subsequent Events note for a discussion of the impact of this on WAP.

Although APiON began research and development on WAP in 1998 it did not commence commercial marketing of it until after March 31, 1999. As a result there were no WAP revenues in the period to that date.

The Statement of Operations reflects the direct operating expenses for WAP, for which APiON maintained separate accounting information. Of APiON's total operating costs of $8,852,000, $6,688,000 can be specifically identified with the respective businesses. Of the residual total overhead costs, mainly consisting of management and administration salaries, and property and recruitment costs, $435,000 has been allocated to the WAP business on the basis of the respective head counts of each business. Management believes that the allocations described above provide a reasonable basis of allocating corporate overhead costs.

The Statement of Assets Acquired and Liabilities Assumed of WAP as at March 31, 1999 reflects the assets acquired and liabilities acquired assumed by Phone.com in the transaction discussed in note 8. Since WAP had no revenue- generating activities prior to March 31, 1999, the accounts receivable and certain trade payables shown in the Statement of Assets Acquired and Liabilities Assumed relate to the Services business, but have been included since they were acquired by Phone.com in conjunction with its acquisition of WAP.

Development Stage Enterprise

Since WAP has not commenced commercial operations, WAP is considered a development stage enterprise as defined by Financial Accounting Standards Board Opinion No. 7, Accounting and Reporting by Development Stage Enterprises. The deficit accumulated in the development stage from May 1998 to March 31, 1999 is $1,231,000.

Financial Instruments and Concentration of Credit Risk

The carrying value of WAP's financial instruments, including cash, accounts receivable, bank loans and amounts due under capital leases, approximates fair value. Financial instruments that subject WAP to concentrations of credit risk consist primarily of trade accounts receivable.

The receivables relate to the sale of services by the Services business, principally to leading mobile telephone operators and manufacturers. Credit risk is concentrated in the United Kingdom. As part of the ordinary course of its business, the management of APiON performed credit evaluations of its customers'

financial condition and did not require collateral from its customers. APiON has had no write-offs of accounts receivable and, based on its evaluation of its accounts receivable collectibility and customer creditworthiness, has recorded no allowance for doubtful accounts receivable.

Research and Development

Research and development costs are expensed as incurred until technological feasibility has been established. Until January 1999, WAP's software was under development and had not yet achieved technological feasibility and, accordingly, only development costs incurred subsequent to that date have been capitalised.

Income taxes

Income taxes are accounted for under the asset and liability method as if WAP was filing a separate return. Deferred tax assets and liabilities are recognised for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognised in income in the period that includes the enactment date. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be recovered.

Tangible fixed assets

The cost of tangible fixed assets is their purchase cost, together with any incidental costs of acquisition. Depreciation is calculated so as to write off the cost of tangible fixed assets, less their estimated residual values, on a straight-line basis over the expected useful economic lives of the assets concerned. The annual rate used for this purpose is 33% per annum.

Capital leases

Leasing agreements, which transfer to WAP substantially all the benefits and risks of ownership of an asset are treated as if the asset had been purchased outright. The assets are included in fixed assets and the capital element of the leasing commitments is shown as obligations under capital leases. Assets held under capital leases are depreciated over the shorter of the lease terms and the useful lives of equivalent owned assets.

Government grants

Revenue grants against revenue expenditure are credited to profit and loss in the same period as the related expenditure is incurred.

Grants against capital expenditure are taken to deferred income and credited to profit and loss on the same basis as depreciation is charged on the related assets. These grants are repayable to the government agency concerned in the event that the relevant assets are disposed of, or cease to be used for the purpose of the trade, within four years of the receipt of the grant. In light of the carve-out of certain fixed assets as described in the Subsequent Event note, management of APiON and Phone.com have met with the government agency concerned. Agreement has been reached that the related grants will not be repayable, and that the shareholders of APiON rather than WAP will assume the liability to repay the grants relating to the carve-out fixed assets in the circumstances of any subsequent disposal or failure to use them for the purpose intended.

Use of estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets.

Comprehensive income

WAP has no material components of other comprehensive income (loss) for all periods presented.

3. Related party transactions

During the period presented WAP purchased services from companies with common shareholders and directors. WAP paid $38,455 during the period for services rendered, at what the directors considered to be commercial market prices.

4. Capitalised Software Development Costs

                                                                       $000's

Management has evaluated the positive and negative evidence impacting the realizability of the deferred tax assets that consist principally of net operating losses carried forward in the UK. Management has considered the short operating history of WAP as well as the uncertainty associated with the Company's future profitability and has concluded that as of March 31, 1999, such deferred tax assets are less likely than not to be realized in the foreseeable future. Therefore management has recorded a full valuation allowance against deferred tax assets. Management evaluates the positive and negative evidence on a quarterly basis.

8. Subsequent events

Subsequent to March 31, 1999, ownership of APiON Limited and APiON Telecoms Limited was consolidated under a new United Kingdom company, also called APiON Telecoms Limited, which was the statutory entity to be acquired by Phone.com.

On October 26, 1999, all of the outstanding capital stock of APiON Telecoms Limited was acquired by Phone.com, Inc. in exchange for 1,196,513 shares of Phone.com common stock.

Immediately prior to the acquisition, APiON spun off its Services business to the vendor shareholders. The transfer involved certain employees, and fixed assets employed in the Services business that had a net book value of $937,000 at March, 31 1999, and related asset finance liabilities of $573,000. The Services business was transferred to the vendor shareholders for a cash payment of $3,254,000, made in addition to the payment made for its book value of net assets acquired.

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements.

We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of AtMotion Inc. at June 30, 1999 and 1998, and the results of its operations and its cash flows for the year ended June 30, 1999 and for the periods from November 10, 1997 (date of incorporation) to June 30, 1998 and 1999, in conformity with generally accepted accounting principles.

NOTES TO FINANCIAL STATEMENTS

June 30, 1999

1. Organization and Significant Accounting Policies

Description of Business

AtMotion, Inc. (the Company), a California corporation, formerly known as Arabesque Communications, Inc., was incorporated on November 10, 1997 for the purpose of designing, developing, producing, and marketing an enhanced wireless telecommunications services platform. This platform will provide a suite of applications, including wireless access to the Internet, that enhances productivity for the user. Through June 30, 1999, the Company was active in product development, the acquisition of equipment and facilities, raising capital, and had no revenues. Accordingly, the Company was in the development stage.

Basis of Presentation

The Company's primary activities since inception have been devoted to developing its product offerings and related technologies, recruiting of key management and technical personnel, and raising capital to fund operations. The Company has been unprofitable since inception. As a result, the financial statements are presented in accordance with Statement of Financial Accounting Standards No. 7, "Accounting and Reporting by Development Stage Enterprises."

For the year ended June 30, 1999, the Company incurred a net loss of $6,301,046. The financial statements have been prepared on a going-concern basis. The Company will require additional financing during fiscal 2000. The Company anticipates raising capital through the sales of preferred stock and believes that sufficient outside financing sources will be available to meet its requirements. If sufficient outside financing is not available, the Company believes it can reduce expenses within the limits of current financial resources and still make progress toward accomplishing its business objectives, although at a slower pace.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Financial Instruments

The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash equivalents are invested in money market funds with major financial institutions.

The Company has classified all investments as available-for-sale. Available- for-sale securities are carried at fair market value based on quoted market prices with unrealized gains and losses, net of tax, reported in shareholders' equity. Realized gains and losses and declines in value judged to be other than temporary on available-for-sale securities are included in interest income. The Company invests its excess cash in high-quality, short-term debt instruments. None of the Company's debt security instruments have maturities greater than one year. Interest and dividends on the investments are included in interest income. As of June 30, 1999 and 1998, there were no material realized gains or losses on investments.

Fair Value of Other Financial Instruments

The carrying and estimated fair values of the Company's other financial instruments at June 30, 1999 were as follows:

                                                                  Estimated

                                                         -------- ---------
Line of credit.......................................... $704,167 $704,167
Capital leases.......................................... $779,791 $779,791

The Company had no outstanding debt at June 30, 1998. The fair value of the Company's obligations under lines of credit and capital leases are based on current rates offered to the Company for similar debt instruments of the same remaining maturities.

Research and Development

Research and development expenses include costs of developing new products and processes as well as design and engineering costs. Such costs are charged to expense as incurred.

Property and Equipment

Property and equipment are carried at cost less accumulated depreciation. Property and equipment are depreciated for financial reporting purposes using the straight-line method over the estimated useful lives of three years.

Accounting for Stock-Based Compensation

The Company has elected to follow Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees" (APB Opinion No. 25), and related interpretations in accounting for its employee stock options because, as discussed in Note 4, the alternative fair value accounting provided for under Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based Compensation" (FAS 123), requires use of option valuation models that were not developed for use in valuing employee stock options. Under APB

F-73

ATMOTION INC.
(a development stage company

formerly known as Arabesque Communications, Inc.)

NOTES TO FINANCIAL STATEMENTS--(Continued)

Opinion No. 25, when the exercise price of the Company's employee stock options equals the market price of the underlying stock on the date of grant, no compensation expense is recognized. As permitted under FAS 123, the Company has elected to follow APB Opinion No. 25 and related interpretations in accounting for stock- based awards to employees and to adopt the "disclosure only" alternative described in FAS 123.

Concentration of Credit Risk

The Company maintains its investments with two financial institutions. The Company performs periodic evaluations of the relative credit standing of the institutions that are considered in the Company's investment strategy. To date, the Company has not incurred losses related to these investments.

Accounting for Internal-Use Computer Software

In March 1998, the American Institute of Certified Public Accountants issued Statement of Position 98-1, "Accounting for the Costs of Computer Software Developed or Obtained for Internal Use" (SOP 98-1). SOP 98-1 provides guidance on accounting for the costs of computer software developed or obtained for internal use and identifies the characteristics of internal-use software. The Company's accounting policy with respect to accounting for computer software developed or obtained for internal use is consistent with SOP 98-1. Software is amortized for financial reporting purposes using the straight-line method over the estimated useful life of three years.

Financial Presentation

Certain prior year amounts on the financial statements have been reclassified to conform to the current year presentation.

Comprehensive Income

In June 1997, the Financial Accounting Standards Board released Statement of Financial Accounting Standards No. 130, "Reporting Comprehensive Income" (FAS 130). FAS 130 establishes standards for the reporting and display of comprehensive income and its components and was effective for fiscal 1999. The adoption of FAS 130 had no impact on net loss or shareholders' equity.

2. Notes Payable and Line of Credit

The Company has a $750,000 line of credit that expires on December 4, 2000, of which $0 was available on June 30, 1999. Borrowings under the line of credit bear interest at the bank's prime rate (7.75% at June 30, 1999). The line of credit requires the Company to place all of its assets as collateral and restricts the payments of cash dividends on the Company's stock. As of June 30, 1999, the Company had approximately $704,000 outstanding under the line of credit.

In connection with the line of credit, the Company issued warrants to purchase up to 3,333 shares of Series B preferred stock at a price of $2.25 per share. The warrants are exercisable immediately and expire ten years from the date of grant. The fair value of the warrants was approximately $5,600 and is being amortized as interest expense over the term of the line of credit.

In February 1999, the Company issued $600,000 of promissory notes that bear interest at 8.00% per annum to related parties. In connection with such notes, the Company issued warrants to purchase up to 26,667 shares

F-74

ATMOTION INC.
(a development stage company

formerly known as Arabesque Communications, Inc.)

NOTES TO FINANCIAL STATEMENTS--(Continued)

of Series B preferred stock at a price of $2.25 per share. The warrants are exercisable immediately and expire ten years from the date of grant. The fair value of the warrants was approximately $45,000 and was originally recorded as capitalized debt issuance costs. In April 1999, the Company converted the promissory notes into Series B preferred stock (see Note 4), which resulted in expensing the unamortized portion of the debt issuance costs.

3. Lease Obligations

The Company leases its facility under a noncancelable operating lease, expiring in January 2003. The agreement provides for a rent escalation each year. Rent expense under operating leases was $360,000 and $47,000 for the year ended June 30, 1999 and for the period from November 10, 1997 (date of incorporation) to June 30, 1998, respectively.

The Company entered into two lease agreements during the year and the total available credit available under these agreements was approximately $1,200,000 as of June 30, 1999. As of June 30, 1999, the Company had $779,791 outstanding under its capital lease agreements. Borrowings under the lease agreements bear interest at the weighted average interest rate of 14.9% as of June 30, 1999. For the assets financed under these agreements, the Company has accounted for the leases as a capital lease. Property and equipment at June 30, 1999 and 1998 include assets under capitalized leases of $937,791 and $0, respectively. Accumulated amortization related to leased assets was $251,038 and $0 at June 30, 1999 and 1998, respectively. In connection with the lease agreements, the Company issued warrants to purchase up to 45,000 shares of Series A preferred stock at a price of $1.00 per share. The warrants are exercisable immediately and expire ten years from the date of grant. The fair value of the warrants was approximately $33,750 and is being amortized as interest expense over the term of the lease agreements.

Future minimum lease payments under capital leases and operating leases are as follows:

The founders' shares are subject to adjustment for certain events, including mergers, stock dividends, stock splits, and other events.

(1) Shares were authorized during the current fiscal year.

All preferred shareholders have the same voting rights as common shareholders. Each share of Series A, A-1, B, and B-1 preferred stock has a number of votes equal to the number of shares of common stock into which it is convertible. As long as a majority of the Series A, A-1, B, and B-1 preferred stock shares originally issued remain outstanding, the holders of the Series A, A-1, B, and B-1 preferred stock, voting as a separate class, shall be entitled to elect one director to the Board of Directors.

In the event of any voluntary or involuntary liquidation of the Company, Series A, A-1, B, and B-1 holders are entitled to liquidation preferences of $1.00, $1.40, $2.25, and $2.75, respectively, per share plus any accrued dividends. Any remaining assets would be distributed to the holders of common stock and preferred stock on a pro rata basis, as if such preferred stock was converted to common stock, until the holders of Series A, A-1, B, and B-1 preferred stock shall have received an additional amount of $2.00, $2.80, $4.50, and $5.50 per share, respectively. All remaining assets would be distributed on a pro rata basis solely among the holders of common stock.

At any time after March 24, 2004, upon written request from the holders of two- thirds or more of the then outstanding shares of any preferred stock, all of the shares requested of such holders' shares of preferred stock shall be redeemed. The redemption amount shall be equal to $1.00, $1.40, $2.25, and $2.75 per share plus any declared but unpaid dividends plus interest at the rate of $0.08, $0.112, $0.18, and $0.22 per share, per annum for Series A, A- 1, B, and B-1 preferred stock, respectively.

NOTES TO FINANCIAL STATEMENTS--(Continued)

The holders of preferred stock are entitled to receive dividends when and if declared by the Board of Directors. The dividends are payable in preference and priority to any payment of any dividend on common stock of the Company. Such dividends are not cumulative, and no right accrues to the holders of preferred stock. No dividends have been declared to date.

Each share of preferred stock is convertible at the option of the holder and is determined by dividing $1.00, $1.40, $2.25, and $2.75 for Series A, A-1, B, and B-1 preferred stock, respectively, by the applicable conversion price. Therefore, at the current conversion price, each share of any preferred stock will convert into one share of common stock. The conversion price per share for any preferred stock shall be adjusted for certain recapitalizations, splits, and combinations. The preferred stock automatically converts into shares of common stock at the conversion price in effect upon the earlier of
(i) the closing of an underwritten public offering registered under the Securities Act of 1933, as amended, covering the offer and sale of common stock at a public offering price of not less than $7.00 per share (adjusted for stock dividends, stock splits, or recapitalizations) with aggregate cash proceeds to the Company of at least $15,000,000; or (ii) the date specified by written consent or agreement of the holders of two-thirds of the then outstanding shares of preferred stock.

The Company recorded accretion of preferred stock of $363,408 in 1999 for the interest accrued to the holders of preferred stock.

Common Stock

The Company is authorized to issue up to 50,000,000 shares of common stock. As of June 30, 1999 and 1998, a total of 3,204,400 and 2,895,000 shares of common stock, respectively, were issued and outstanding.

Common stock was reserved for issuance as follows:

Stock Plan

The Company's 1998 Stock Plan (the Plan) provides for the granting of incentive stock options and nonstatutory stock options as determined by the Board of Directors. Per the Plan, the exercise price of incentive stock options and nonstatutory stock options granted to an employee or service providers, who respectively at the time of grant own stock representing more than 10% of the voting power of all classes of the stock of the Company, shall be granted at no less than 110% of the fair market value per share of the common stock on the date of grant. The exercise price of nonstatutory stock options granted to other service providers shall be at no less than 85% of the fair market value per share of the common stock on the date of grant. Except in the case of options granted to officers, directors, and consultants, options shall become exercisable at a rate of no less than 20% per year over five years from the date of the option grant. All option grants shall be eligible for early exercise, but unvested shares shall be subject to repurchase. The term of each option grant will be no more than ten years. However, in the case of an incentive stock option issued to an optionee who, at the time of grant, owns stock representing more than 10% of the voting power of all classes of the stock of the Company, the term of the option will be no more than five years.

Rights to immediately purchase stock may also be granted under the Plan with terms, conditions, and restrictions determined by the Board of Directors. Except for shares purchased by officers, directors, and consultants, shares acquired through stock purchase rights vest over a period not to exceed five years with 20% vesting each year. Any unvested shares acquired are subject to repurchase by the Company.

Information with respect to the Plan is summarized as follows:

At June 30, 1999, 67,382 options were vested, and 319,231 shares were subject to repurchase by the Company at the original issuance price. At June 30, 1998, no options were vested, and 85,000 shares were subject to repurchase by the Company at the original issuance price.

Stock-Based Compensation

Pro forma information regarding net loss is required by FAS 123, which also requires that the information be determined as if the Company has accounted for its employee stock options granted during the years ended June 30, 1999 and 1998 under the fair value method of FAS 123. The fair value for options was estimated at the date of grant using the minimum value method with the following weighted average assumptions: a risk-free interest rate of 6.4% and 5.4% for 1999 and 1998, respectively; no dividend yield or volatility factors of the expected market price of the Company's common stock for both years; and a weighted average expected life of the option of ten years for both years.

F-78

ATMOTION INC.
(a development stage company

formerly known as Arabesque Communications, Inc.)

NOTES TO FINANCIAL STATEMENTS--(Continued)

The option valuation models were developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions, including the expected life of the option. Because the Company's employee stock options have characteristics significantly different from those of traded options and because changes in the subjective input assumptions can materially affect the fair value estimate, in management's opinion, the existing models do not necessarily provide a reliable single measure of the fair value of its employee stock options.

The difference between the reported loss and the pro forma loss for the years ended June 30, 1999 and 1998 was not material.

The options' weighted average grant-date fair value, which is the value assigned to the options under FAS 123, was $0.10 and $0.04 for options granted during 1999 and 1998, respectively.

The pro forma impact of options on the net loss for the year ended June 30, 1999 is not representative of the effects on net income (loss) for future years, as future years will include the effects of options vesting as well as the impact of multiple years of stock option grants. The full effect of FAS 123 will not be fully reflected until 2001.

Warrants to Consultants

During the year ended June 30, 1999, the Company issued warrants to consultants to purchase up to 27,900 shares of common stock at a price ranging from $0.10 to $0.35 per share. The warrants are exercisable immediately, and the vesting terms range from immediately to two years. The fair value of the warrants was approximately $2,500 and was expensed during the year. The warrants will be remeasured to fair value until they have vested.

5. Related Parties

During the year ended June 30, 1999 and the period from November 10, 1997 (date of incorporation) to June 30, 1998, the Company incurred legal fees of approximately $87,000 and $53,000, respectively, for services rendered by Wilson Sonsini Goodrich & Rosati, a law firm in which a current member of the Board of Directors of the Company is a senior partner. As of June 30, 1999 and 1998, the amount owed to Wilson Sonsini Goodrich & Rosati was approximately $23,000 and $26,000, respectively.

During the year ended June 30, 1999, one of the Company's suppliers became an investor in the Company. During the year, the Company purchased approximately $500,000 from the supplier. As of June 30, 1999, the Company had an outstanding payable balance to the supplier of approximately $218,000.

6. Income Taxes

The Company accounts for income taxes under the provisions of Statement of Financial Accounting Standards No. 109 "Accounting for Income Taxes" (FAS 109), which provides for the establishment of deferred tax assets and liabilities for the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. As of June 30, 1999 and 1998, the Company has total deferred tax assets of approximately $3,003,000 and $391,000, respectively, relating primarily to federal and California net operating loss carryforwards and research and development credits. The valuation allowance increased by $2,612,000 and $391,000 during the years ended

F-79

ATMOTION INC.
(a development stage company

formerly known as Arabesque Communications, Inc.)

NOTES TO FINANCIAL STATEMENTS--(Continued)

June 30, 1999 and 1998, respectively. The net deferred asset has been fully offset by a valuation allowance as it is "more likely than not" that the Company will realize the benefit of this asset in the future. The federal and California net operating loss carryforwards of approximately $5,766,000 expire in 2013 and 2019, respectively. Utilization of the net operating losses may be subject to a substantial annual limitation due to the ownership change regulations provided by the Internal Revenue Code and similar state provisions, which may result in the expiration of net operating losses before utilization.

7. Subsequent Event (Unaudited)

In September 1999, the Company entered into a new equipment line of credit agreement with the same financial institution in which it has a $750,000 equipment lease (see Note 3). The new equipment line of credit increases the Company's borrowing capacity with the financial institution from $750,000 to $2,000,000. The total amount borrowed under the two agreements shall not exceed $2,000,000. Borrowings under the equipment line of credit bear interest at 13%. The equipment line of credit requires the Company to place all of the assets financed under the line as collateral.

In connection with the equipment line of credit, the Company issued warrants to purchase up to 17,818 shares of Series B-1 preferred stock at a price of $2.75 per share. The warrants are exercisable immediately and expire ten years from the date of grant. The fair value of the warrants is approximately $37,000 and will be amortized as interest expense over the term of the equipment line of credit.

8. Year 2000 (Unaudited)

The Company has determined that its current computer systems are year 2000 compliant and would function properly with respect to dates in the year 2000 and beyond. The Company has not noted any year 2000 issues with its products; however, the Company has not performed significant testing with respect to its products. The cost of year 2000 initiatives is not expected to be material to the Company's results of operations or financial position. The Company has yet to initiate discussions with all of its third-party relationships to ensure that those parties have appropriate plans in place to correct all of their year 2000 issues. While the Company believes its planning efforts are adequate to address its year 2000 concerns, there can be no assurance that the systems and products of other companies on which the Company's operations rely will be converted on a timely basis and will not have a material adverse effect on the Company's results of operations.

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS
December 31, 1999

1. Basis of Presentation

The unaudited condensed financial statements included herein have been prepared by the Company in accordance with generally accepted accounting principles and reflect all adjustments, consisting only of normal recurring adjustments which in the opinion of management are necessary to fairly state the Company's financial position, results of operations, and cash flows for the periods presented. Through December 31, 1999, the Company was active in product development, the acquisition of equipment and facilities, raising capital, and had no revenues. Accordingly, the Company was in the development stage, and the financial statements have been prepared on a going-concern basis. The results of operations for the six months ended December 31, 1999 are not necessarily indicative of the results to be expected for any subsequent quarter or for the entire fiscal year ended June 30, 2000.

2 Subsequent Event

On December 21, 1999, the Company signed a definitive agreement to be acquired by Phone.com, Inc. In connection with the acquisition, which was completed on February 8, 2000, Phone.com issued 2,280,287 shares of its common stock in exchange for all of the outstanding common stock and preferred stock of AtMotion, and assumed options and warrants of AtMotion for total consideration valued at approximately $285.2 million.

REPORT OF ERNST & YOUNG, INDEPENDENT AUDITORS

To the Board of Directors
Paragon Software (Holdings) Limited

We have audited the accompanying consolidated balance sheets of Paragon Software (Holdings) Limited as of December 31, 1999 and 1998, and the related consolidated statements of operations, shareholders' equity, and cash flows for each of the two years in the period ended December 31, 1999. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with United Kingdom auditing standards, which do not differ in any significant respect from United States generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Paragon Software (Holdings) Limited at December 31, 1999 and 1998, and the consolidated results of its operations and its cash flows for each of the two years in the period ended December 31, 1999, in conformity with accounting principles generally accepted in the United States.

PARAGON SOFTWARE (HOLDINGS) LIMITED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Accounting Policies

Accounting convention

The financial statements are prepared in accordance with accounting principles generally accepted in the United States.

Basis of consolidation

The financial statements consolidate the accounts of Paragon Software (Holdings) Limited (the "Company") and all its subsidiary undertakings drawn up to 31 December each year. As more fully described in note 2, on 10 February 1998 the company merged with Paragon Software Limited and Paragon Software (Developments) Limited. The transaction was accounted for as a combination of entities under common control in a manner similar to pooling of interests and, accordingly, all financial data provided herein includes the results of these companies.

Use of estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Revenue recognition

Paragon recognises revenue upon shipment when no significant vendor obligations remain and collection of the receivable, net of provisions for estimated future returns, is probable. Paragon offers the right of return of its products under various programs. The company estimates and maintains reserves for product returns.

Cash equivalents

Paragon considers investments in highly liquid instruments purchased with an original maturity of 90 days or less to be cash equivalents. All of the company's cash equivalents are classified as available for sale as of the balance sheet date. These securities are reported at fair market value.

Development costs

Development costs on separately identified specific projects, the outcome of which has been assessed with reasonable certainty, are capitalised to the extent that their recovery can reasonably be regarded as assured and are amortised on a unit basis over a maximum of 30 months. Other development expenditure is written off against profits in the year in which it is incurred.

Intellectual Property Rights

Intellectual property rights have been recorded at cost and are being amortised evenly over a period of three years, their expected useful life.

F-90

PARAGON SOFTWARE (HOLDINGS) LIMITED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

Depreciation

Depreciation is provided on all tangible fixed assets at rates calculated to write off cost, less estimated residual value, of each asset evenly over its expected useful life, as follows:

Computer equipment............................................ over 3 years
Software...................................................... over 3 years
Office equipment.............................................. over 4 years
Fixtures and fittings......................................... over 4 years

Inventories

Inventories, consisting principally of consumable products, are stated at the lower of cost and net realisable value. Cost is determined on a first in first out basis.

Deferred taxation

Deferred taxation is provided on the liability method on all timing differences which are expected to reverse in the future, calculated at the rate at which it is estimated that tax will be payable.

Foreign currencies

Transactions in foreign currencies are recorded at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies are retranslated at the rate of exchange ruling at the balance sheet date. All differences are taken to the profit and loss account.

The accounts of overseas subsidiary companies are translated at the rate of exchange ruling at the balance sheet date. The exchange difference arising on the retranslation of opening net assets is taken directly to reserves. All other translation differences are taken to the profit and loss account.

Leasing

Assets acquired under capital leases are capitalised as fixed assets. The amount capitalised is that sum for which the leased asset could be purchased at the start of the lease, this sum also being treated as a liability.

Depreciation on such leased assets is provided at rates calculated to write off the capitalised cost over the shorter of the lease term and the asset's economic life. Lease payments are apportioned between financing charges (computed on the basis of implicit interest rates) and a reduction in the original liability.

Rentals paid under operating leases are expensed on a straight line basis over the term of the lease.

Share based compensation

Where share options are granted to employees the company recognises as a charge in the profit and loss account the difference between the fair market value of the shares at the date the award is made to participants in the scheme and the amount of the consideration that participants may be required to pay for the shares. This charge is spread evenly over the period the share options vest.

For share options granted under Stock Appreciation Right plans (SAR), the compensation related to the grant of the option is determined based on the market price at the date the recipient exercises their option. Until exercise has occurred, the compensation is determined by reference to the market price at the end of each

F-91

PARAGON SOFTWARE (HOLDINGS) LIMITED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

accounting period. The difference in value of the option using the current accounting period's market price and the last accounting period's market price is charged to the profit and loss account.

Share options were also granted to a consultant. The difference between the fair value of the shares at the date of the grant and the amount of consideration that the participants may be required to pay for the shares is recorded as a charge to the profit and loss account over the vesting period.

2. Business Combinations

On 10 February 1998, 948,998 (Pounds)1 ordinary shares were issued fully paid in consideration on the merger with Paragon Software Limited and Paragon Software (Developments) Limited (the subsidiaries'). The subsidiaries principal activities are the development, marketing and selling of software products linking mobile phones to personal computers worldwide.

The combination has been accounted for as a combination of interests under common control in a manner similar to the pooling of interests and accordingly all financial data presented herein has been restated to include the results of the subsidiaries. The following table sets forth the composition of combined net revenue and net loss for the periods indicated. Information for 1998 with respect to the subsidiaries reflects the period from 1 January 1998 to 10 February 1998, the date of the combination.

The realisation of the deferred tax asset is dependent on the group's ability to generate approximately (Pounds) 2.5 million of taxable income. Management are currently unable to estimate the timing of the generation of this income and have therefore set a valuation allowance in full against the asset. This allowance will be reviewed annually.

9. "C' Redeemable Convertible Preferred Shares ("C' Shares)

During 1999, 2,727,148 "C' shares of par value 10p per share were allotted for (Pounds) 8,564,020, gross of issue costs of (Pounds) 108,386.

"C' shares rank pari passu in all respects to voting rights with other classes of shareholders.

The "C' preferred shareholders have priority over all other shareholders to a non-cumulative dividend of 8%. After accounting for the preferential dividend all classes rank pari passu in respect of further dividends.

On a winding up of the company, the "C' preferred shareholders have the right to receive, in priority to all other shareholders, the subscription price of the "C' preferred shares plus any dividends in arrears, the "B' preferred shareholders then have the right to receive, in priority to "A' preferred and ordinary shareholders, the subscription price of the "B' preferred shares plus any dividends in arrears. The "A' preferred shareholders have the right to receive, subject to the rights of the "B' and "C' preferred shareholders, but in priority to ordinary shareholders, the subscription price of the "A' preferred shares plus any dividends in arrears. Any remaining balance will then be shared pari passu between the "B' and "C' preferred shareholders and the ordinary shareholders.

A holder of any class of preferred shares is entitled to convert each share held into such number of fully paid ordinary shares as determined by the Articles of Association.

If approval of 50% of the "C' preferred shareholders is given, the company shall redeem at the subscription price the shares of such holder giving notice.

PARAGON SOFTWARE (HOLDINGS) LIMITED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

During 1999 the company subdivided each (Pounds) 1 ordinary, "A' preferred and "B' preferred shares into 10 10p ordinary, "A' preferred and "B' preferred shares respectively.

The company has an unapproved share option plan under which options to subscribe for the company's shares have been awarded to consultants and employees. The Board of Directors determines the term of each award and the award price. The awards are made at the discretion of the Board of Directors. At the beginning of 1998 there were no options under the plan in place. During 1998 options under this plan were granted over 615,000 shares exercisable at 10p each, between 25 October 2001 and 25 October 2007. During 1999 further options were granted over 1,360,000 ordinary shares exercisable at 10p each, between 1 April 2002 and 1 April 2008. No options were exercised or lapsed during 1998 or 1999.

The "C' preferred shareholders have priority over all other shareholders to a non-cumulative dividend of 8%. After accounting for the preferential dividend all classes rank pari passu in respect of further dividends.

On a winding up of the company, the "C' preferred shareholders have the right to receive, in priority to all other shareholders, the subscription price of the "C' preferred shares plus any dividends in arrears, the "B' preferred shareholders then have the right to receive, in priority to "A' preferred and ordinary shareholders, the subscription price of the "B' preferred shares plus any dividends in arrears. The "A' preferred shareholders have the right to receive, subject to the rights of the "B' and "C' preferred shareholders, but in priority to ordinary shareholders, the subscription price of the "A' preferred shares plus any dividends in arrears. Any remaining balance will then be shared pari passu between the "B' and "C' preferred shareholders and the ordinary shareholders.

A holder of any class of preferred shares is entitled to convert each share held into such number of fully paid ordinary shares as determined by the Articles of Association.

If approval of 50% of the "C' preferred shareholders is given, the company shall redeem at the subscription price the shares of such holder giving notice.

NOTES TO FINANCIAL STATEMENTS
December 31, 1999

1. Organization and Summary of Significant Accounting Policies

Nature of Operations

Onebox.com, Inc. (the "Company") was incorporated in the state of Delaware on May 20, 1998. The Company is engaged in web-based services that simplify and reduce the cost of communications for consumers and businesses.

The Company has incurred losses to date of approximately $13,200,000. The Company expects such losses to continue until the Company successfully completes development and market introduction of its products. Consequently, management recognizes the need to raise additional funds from outside sources. Management believes currently available resources along with proceeds from Series C preferred stock offering (see Note 8) will provide sufficient funds to enable the Company to meet its obligations through at least December 31, 2000. If anticipated operations are not achieved, management has the intent and believes it has the ability to delay or reduce expenditures so as not to require additional financial resources if such resources were not available.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and the accompanying notes. Actual results could differ materially from these estimates.

Revenue Recognition

Revenues are derived principally from short-term on-line advertising contracts in which the Company guarantees a minimum number of impressions (a view of an advertisement by a consumer) for a fixed fee. These revenues are generally recognized ratably over the term of the agreements, provided that the Company does not have any significant remaining obligations and collection of the resulting receivable is probable. To the extent that impression deliveries do not meet the guarantees, the Company defers recognition of the corresponding revenues.

Revenues are derived principally from a Service Distribution Agreement (see Note 4) in which the Company agrees to co-brand an Internet Website. The Company receives 25% of the advertising revenue generated by the co-branded Website, which is determined and remitted to Onebox.com directly by the Website's co-owner.

Cash, Cash Equivalents, and Short-Term Investments

Onebox.com generally invests its excess cash in money market accounts, certificates of deposits and U.S. Treasury bills. Onebox.com considers all highly liquid investments with a maturity from date from original purchase of three months or less to be cash equivalents. The carrying amount reported in the balance sheet for cash and cash equivalents approximates its fair value.

Onebox.com classifies its short-term investment as "available-for-sale." Onebox.com considers all investments with a maturity date of one year from date of original purchase to be short-term investments. These investments are recorded at fair value based on quoted market prices. The amortized cost of these investments approximates their fair value. Unrealized gains and losses are not material and have, therefore, not been shown separately.

NOTES TO FINANCIAL STATEMENTS--(Continued)

Property and Equipment

Property and equipment are stated at cost, less accumulated depreciation which is provided using the straight-line method over the estimated useful lives of the assets, generally three to five years. Equipment purchased under capital lease is amortized on a straight-line basis over the lesser of the estimated useful life of the asset or the lease term.

Advertising Expense

Advertising is expensed as incurred. Advertising expense was approximately $2,600,000 and none for the year ended December 31, 1999 and the period from inception (May 20, 1998) to December 31, 1998, respectively.

Stock-Based Compensation

The Company accounts for stock-based compensation using the intrinsic value method prescribed in Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees ("APB 25")," and has adopted the disclosure only alternative of Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based Compensation" ("SFAS 123").

Research and Development

Research and development expenditures are generally charged to operations as incurred. Statement of Financial Accounting Standards No. 86, "Accounting for the Costs of Computer Software to Be Sold, Leased or Otherwise Marketed," requires the capitalization of certain software development costs subsequent to the establishment of technological feasibility. Based on the Company's product development process, technological feasibility is established upon the completion of a working model. Costs incurred by the Company between completion of the working model and the point at which the product is ready for general release have been insignificant. Accordingly, the Company has charged all such costs to research and development expense in the period incurred.

Onebox.com adopted SOP 98-1, "Accounting for the Costs of Computer Software Developed or Obtained for Internal Use" during 1999, which requires capitalization of certain costs incurred during the development of internal use software. Through December 31, 1999 capitalizable costs incurred have not been significant for any development project. Accordingly, Onebox.com has charged all costs to research and development expense in the periods they were incurred.

Recent Pronouncements

In June 1998, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 133, "Accounting for Derivative Instruments and Hedging Activities." ("SFAS No. 133"). SFAS No. 133 establishes methods for derivative financial instruments and hedging activities related to those instruments, as well as other hedging activities. Because Onebox.com does not currently hold any derivative instruments and does not engage in hedging activities, the adoption of SFAS No. 133 is not expected to have a significant impact on its financial position, results of operations or cash flows. Onebox.com will be required to implement SFAS No. 133, as amended, for the year ending December 31, 2001.

In December 1999, the SEC issued Staff Accounting Bulletin No. 101 ("SAB 101"). SAB 101 summarizes the Staff's views in applying generally accepted accounting principles to revenue recognition. The Company believes that its current revenue recognition principles comply with SAB 101.

3. Purchased Software License

In December 1999, the Company signed a $1,840,000 Software License Agreement. Under the agreement, the Company paid $1,150,000 for a software license for software to be integrated into the Onebox.com product, subject to maximum of 35 million users. The license will be amortized to cost of goods sold as products are sold. In addition to the license, the Company purchased three years of technical support and maintenance for $690,000, which will be amortized over the three years, beginning in December 1999.

4. Service Distribution Agreement

In September 1999, the Company entered into a two-year Service Distribution Agreement to co-brand an Internet website. The agreement calls for Onebox.com to pay $2,250,000 for distribution, marketing, and advertising of the co- branded site. The payment will be made in two installments; $1,500,000 on the effective date of the agreement and $750,000 payable on the first anniversary of the effective date. These fees are being amortized over the two years, beginning in September 1999, and are classified as a current asset on the balance sheet. In addition to these payments, Onebox.com will be paid 25% of the advertising revenue generated by the co-branded website. Revenue related to this agreement was $84,559 for the year ended December 31, 1999.

6. Stockholders' Equity

Convertible Preferred Stock

In October 1998, the Company issued 9,765,000 Series A convertible preferred shares at a price of $0.33 per share under a stock purchase agreement. In May 1999, the Company issued 7,064,684 Series B convertible preferred shares at a price of $1.91 per share under a stock purchase agreement.

Each share of Series A and B convertible preferred stock is, at the option of the holder, convertible into one share of common stock, subject to certain adjustments for dilution, if any, resulting from future stock issuances. The outstanding shares of convertible preferred stock automatically convert into common stock (i) upon the affirmative vote of the majority of each class of preferred stock or (ii) immediately prior to the closing of an underwritten public offering of common stock under the Securities Act of 1933 provided that, with respect to Series A, the Company receives at least $15,000,000 in gross proceeds and the price per share is at least $2.50 and, with respect to Series B, the product of the price per share to the public and the aggregate number of shares of the Company's common stock outstanding prior to such an offering is at least $150,000,000 and aggregate proceeds to the Company are not less than $15,000,000.

Series A and B convertible preferred stockholders are entitled to noncumulative dividends of $0.03 and $0.15 per share, respectively. Dividends will be paid only when declared by the board of directors out of legally available funds. No dividends have been declared as of December 31, 1999.

Series A and B convertible preferred stock have liquidation preferences of $0.33 and $3.81 per share, respectively, with the remaining liquidation occurring on a pro rata basis between common and preferred stock until holders of Series A and B preferred stock have received an aggregate, which includes the initial liquidation preference, of $1.00 and $5.72 per share, respectively.

The Series A and B convertible preferred stockholders have voting rights equal to the common shares issuable upon conversion of their preferred shares.

Common Stock

The Company has sold 9,110,195 shares of common stock to employees and investors for $0.001 to $0.50 per share. Of these shares, 8,565,300 are subject to repurchase by the Company, at the price paid by the stockholder, in the event of termination of services by the stockholder to the Company; the repurchase right lapses over a 48-month period. Of these shares, 310,200 are subject to repurchase until the sooner of the date on which the last of four milestones are met or five years from April 1999. During the period from inception (May 20, 1998) to December 31, 1999, 2,440,702 shares of common stock were repurchased. As of December 31, 1999, the Company had 2,377,800 shares of common stock outstanding subject to repurchase.

At December 31, 1999, an aggregate of 20,066,049 shares of common stock were reserved for issuance upon exercise of warrants, the conversion of preferred stock, outstanding stock options and stock options reserved for issuance.

Stock Warrants

In conjunction with a capital lease agreement, the Company issued the lenders warrants to purchase an aggregate of 81,301 shares of its Series A convertible preferred stock at $1.47 per share. The warrants shall be exercisable for a period of (i) seven years or (ii) three years from the effective date of the company's initial

public offering, whichever is earlier. The warrants were valued using the Black-Scholes model (0.5 volatility, seven year life, $1.47 exercise price, and a 6% risk-free interest rate). The total value of $70,461 will be amortized to interest expense over the term of the capital lease.

1999 Incentive Stock Plan

As discussed in Note 1, the Company has elected to follow APB 25 and related interpretations in accounting for its employee stock options. The alternative fair value accounting provided for under Financial Accounting Standards Board Statement No. 123, "Accounting for Stock-Based Compensation" ("FAS 123"), requires use of option valuation models that were not developed for use in valuing employee stock options. Under APB 25, when the exercise price of the Company's employee stock options equals the market price of the underlying stock on the date of grant, no compensation expense is recognized.

During the period ended December 31, 1999, the Company adopted the 1999 Stock Plan (the "Plan"). Under the Plan, up to 9,664,100 shares of the Company's common stock may be granted as options or sold to eligible participants. Under the Plan, options to purchase common stock may be granted at no less than 85% of the fair value on the date of the grant (110% of fair value in certain instances), as determined by the board of directors. Options generally vest over a 48-month period and have a maximum term of ten years.

Pro forma information regarding net income is required by FAS 123, which also requires that the information be determined as if the Company has accounted for its employee stock options under the fair value method of FAS
123. The fair value of these options was estimated at the date of grant using the minimum value method option pricing model with the following weighted- average assumptions for the period from inception (May 20, 1998) to December 31, 1999: risk-free interest rates of 6%; a dividend yield of 0%; and a weighted-average expected life of the option of five years.

The effect of applying FAS 123 to the Company's stock option awards did not result in pro forma net loss that was materially different from amounts reported. Therefore, such pro forma information is not separately presented herein. Future pro forma net income/loss results may be materially different from actual amounts reported.

Information with respect to stock option activity is summarized as follows:

NOTES TO FINANCIAL STATEMENTS--(Continued)

As of December 31, 1999, no options to purchase shares were exercisable. The weighted-average remaining contractual life of all outstanding options is 9.2 years.

7. Income Taxes

As of December 31, 1999, the Company had federal and state net operating loss carryforwards of approximately $13.2 million and $10.2 million, respectively. The Company also had federal research and development tax credit carryforwards of approximately $100,000. The federal and state net operating loss and credit carryforwards will expire at various dates beginning in the year 2006 through 2019, if not utilized.

Utilization of the federal and state net operating loss and credit carryforwards may be subject to a substantial annual limitation due to the "change in ownership" provisions of the Internal Revenue Code of 1986. The annual limitation may result in the expiration of net operating losses and credits before utilization.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets for financial reporting and the amount used for income tax purposes. Significant components of the Company's deferred tax assets for federal and state income taxes as of December 31 are as follows:

                                                               1999    1998

NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS
March 31, 2000

1. Basis of Presentation

The unaudited condensed financial statements included herein have been prepared by the Company in accordance with generally accepted accounting principles and reflect all adjustments, consisting only of normal recurring adjustments which in the opinion of management are necessary to fairly state the Company's financial position, results of operations, and cash flows for the periods presented. Through March 31, 2000, the Company was active in product development, the acquisition of equipment and facilities, raising capital, and had virtually no revenues. Accordingly, the Company was in the development stage, and the financial statements have been prepared on a going- concern basis. The results of operations for the three months ended March 31, 2000 are not necessarily indicative of the results to be expected for any subsequent quarter.

2. Subsequent Event

On February 14, 2000, the Company signed a definitive agreement to be acquired by Phone.com, Inc. In connection with the acquisition, which was completed on April 14, 2000, Phone.com issued approximately 6.5 million shares of its common stock in exchange for all of the outstanding common stock and preferred stock of Onebox, and assumed options and warrants of Onebox for total consideration valued at approximately $800 million.

NOTES TO FINANCIAL STATEMENTS

(Information at September 30, 1999 and for the nine months ended September 30, 1998 and September 30, 1999 is unaudited)

1. Summary of Significant Accounting Policies

Organization and Business

Telarc, Inc. (the Company), a New York Corporation, provides Internet, SS7, SMS, and Paging products, middleware and consulting solutions for the telecommunication industries. The Company was incorporated in January 1997 through the issuance of 10 shares of common stock with no par value.

Interim Financial Information (Unaudited)

The accompanying balance sheet as of September 30, 1999, the statements of income and cash flows for the nine months ended September 30, 1999 and 1998, and the statement of shareholder's equity for the nine months ended September 30, 1999, are unaudited. In the opinion of management, the unaudited financial statements have been prepared on the same basis as the audited financial statements and include all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of the financial position, results of operations, and cash flows for the interim periods. The results of operations for the nine months ended September 30, 1999, are not necessarily indicative of operating results to be expected for the full fiscal year.

Cash Equivalents

The Company considers investments in money market funds to be cash equivalents.

Concentration of Credit Risk, Other Risks and Significant Customers

The Company grants credit terms in the normal course of business to its customers. The Company does not require collateral. Credit losses have been within management's expectations and potential uncollectible accounts have been provided for in the financial statements. The Company's only employee is its sole shareholder. For the years ended December 31, 1997 and 1998, salary and related benefits paid to the sole shareholder totaled $101,200 and $160,000, respectively, and have been classified as cost of services in the accompanying statements of income. For the nine months ended September 30, 1998 and 1999, salary and related benefits paid to the sole shareholder totaled $126,000 and $175,000, respectively, and have been classified as cost of services in the accompanying statements of income.

Total revenues from the Company's two largest customers in the years ended December 31, 1997 and 1998, accounted for 49% and 48% of total revenues, respectively. Total revenues from the Company's two largest customers in the nine months ended September 30, 1998 and 1999, accounted for 49% and 57% of total revenues, respectively. One of the Company's two largest customers for the nine months ended September 30, 1999, was Software.com, Inc. At December 31, 1997 and 1998, and September 30, 1999, the largest customer receivable balances totaled 63%, 40% and 44% of total accounts receivable, respectively.

Furniture and fixtures............................................ 7 years

NOTES TO FINANCIAL STATEMENTS--(Continued)

(Information at September 30, 1999 and for the nine months ended September 30, 1998 and September 30, 1999 is unaudited)

Income Taxes

The Company has been organized for federal and state income tax purposes as an S Corporation under Subchapter S of the Internal Revenue Code of 1986, as amended, and comparable state laws. As a result, the earnings of the Company are included in the taxable income of the Company's sole shareholder at his individual federal and state income tax rates, rather than that of the Company.

Revenue Recognition

In October 1997, the Accounting Standards Executive Committee issued Statement of Position 97-2 (SOP 97-2), which was amended by SOP 98-4 and SOP 98-9, "Software Revenue Recognition." These statements provide guidance on applying generally accepted accounting principles in recognizing revenue on software transactions. This guidance is effective for the Company's transactions entered into subsequent to January 1, 1998. The application of certain provisions was deferred until fiscal years beginning on or after March 15, 1999. Final adoption of these provisions is not expected to have a material impact on the Company's financial condition or results of operation.

Software Licenses Revenue. The Company recognizes revenue from sales of software upon delivery of the license key to the customer, provided that persuasive evidence of an arrangement exists, the license fee is fixed and determinable, and collection of the fee is considered probable.

Services Revenue. Services revenue consists of consulting revenue and support and maintenance contracts related to software licenses. Consulting revenue are recognized on a time and materials basis as the services are performed. Support and maintenance contracts generally call for the company to provide technical support and software updates and upgrades to customers. Support and maintenance revenue is recognized ratably over the support or maintenance period.

Fair Value of Financial Instruments

The carrying amounts reported in the balance sheets for cash and cash equivalents, accounts receivable and accounts payable, approximate their fair values due to the short-term nature of these financial instruments

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ materially from those estimates.

2. Property and Equipment

The major components of property and equipment are as follows (in thousands):

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Information at March 31, 2000 and for the three months ended March 31, 2000 and March 31, 1999 is unaudited)

1. Summary of Significant Accounting Policies

Business and Organization

ISPNews, Inc. (ISPNews), a privately held company, was incorporated in Michigan in March of 1997. ISPNews is a service provider of usenet technologies solutions.

Highwind Software, Inc. (Highwind), a privately held company, was incorporated in Massachusetts in July of 1996. Highwind is a market leader in providing carrier-class discussion server infrastructure software to service providers worldwide.

On January 8, 1999, ISPNews and Highwind entered into an Agreement of Reorganization ("the Agreement") by which a newly formed company was incorporated in the state of Delaware under the name ISPNews--Highwind Inc. Pursuant to the terms of the Agreement, each share of issued and outstanding ISPNews common stock (12,109shares) was exchanged for 247.8 shares of ISPNews--Highwind Inc. common stock (2,999,994 shares). Additionally, as a condition of closing the Agreement, ISPNews shareholders contributed $1,070,000 to ISPNews--Highwind Inc. in return for 1,070,000 shares of common stock. ISPNews--Highwind Inc. also issued 2,004,677 shares of common stock , paid $1,007,000 in cash and issued a promissory note for $353,000 all to the sole shareholder of Highwind in exchange for 100% of the common stock of Highwind. For financial reporting purposes, the formation of ISPNews--Highwind Inc. was accounted for as the purchase by ISPNews of Highwind and accordingly, the excess of the purchase price over the fair value of the net assets acquired was allocated to goodwill (see Note 2). The results of operations from January 1, 1999 through January 8, 1999, were not significant.

In April of 1999, ISPNews--Highwind Inc. changed its name to bCandid Corporation ("bCandid" or the "Company").

Basis of Presentation

The accompanying consolidated financial statements of the Company and its subsidiaries have been prepared in accordance with generally accepted accounting principles. All significant intercompany balances and transactions have been eliminated.

Interim Financial Statements

The accompanying consolidated balance sheet as of March 31, 2000 the consolidated statements of operations and consolidated statement of cash flows for the three months ended March 31, 1999 and 2000, and the statement of shareholders' equity for the three months ended March 31, 2000, are unaudited. In the opinion of management, the unaudited financial statements have been prepared on the same basis as the audited financial statements and include all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of the financial position, results of operations, and cash flows for the interim periods. The results of operations for the three months ended March 31, 2000, are not necessarily indicative of operating results to be expected for the full fiscal year.

Significant Customers and Concentration of Credit Risk

The Company's customers are not concentrated in any geographic region. During the year ended December 31, 1999, the Company had no significant customers. At December 31, 1999, one customer accounted

for 13% of accounts receivable. The Company routinely assesses the financial strength of significant customers but generally does not require collateral. The Company establishes an allowance for potential credit losses based on the credit risk for specific customers, historical trends and other information; such losses have been within management's expectations.

Revenue Recognition

In October 1997, the American Institute of Certified Public Accountants issued Statement of Position 97-2 (SOP 97-2), which was amended by SOP 98-4 and SOP 98-9, "Software Revenue Recognition." These statements provide guidance on applying generally accepted accounting principles in recognizing revenue on software transactions. This guidance is effective for the Company's transactions entered into subsequent to January 1, 1998. The application of certain provisions was deferred until fiscal years beginning on or after March 15, 1999. Final adoption of these provisions is not expected to have a material impact on the Company's financial condition or results of operations.

The Company recognizes revenue from sales of products and software licenses upon shipment of the product or issuance of a software access key to the customer, provided that persuasive evidence of an agreement exists, the license fee is fixed and determinable, and collection of the fee is considered probable. Revenue from maintenance contracts generally call for the Company to provide technical support and software updates and upgrades to customers and is recognized ratably over the maintenance period, principally one year. Training and other consulting services are recognized as the services are performed.

In December 1999, the SEC issued Staff Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition in Financial Statements." SAB 101 summarizes certain of the SEC's views in applying generally accepted accounting principles to revenue recognition in financial statements. The Company is required to adopt SAB 101 in the first quarter of fiscal 2001. Management does not expect the adoption of SAB 101 to have a material effect on the Company's operations or financial position.

Research and Development

Pursuant to Statement of Financial Accounting Standards No. 86 "Accounting for the Costs of Computer Software to be Sold, Leased, or Otherwise Marketed," development costs related to software products are expensed as incurred until the "technological feasibility" of the product has been established. Because of the relatively short time period between "technological feasibility" and product release, and the insignificant amount of costs incurred during such period, no software development costs have been capitalized.

Cash Equivalents

Cash equivalents consist of investments with original maturities of three months or less from the date of purchase.

Equipment and Improvements

Equipment and improvements are stated at cost. Depreciation is provided for by the straight-line method over the estimated useful lives ranging from 2-5 years. Leasehold improvements are amortized using the straight-line method over the shorter of their estimated useful lives or the lease term.

(Information at March 31, 2000 and for the three months ended March 31, 2000 and March 31, 1999 is unaudited)

Advertising Costs

Advertising costs are expensed as incurred. Advertising costs for the year ended December 31, 1999 amounted to $282,000.

Accounting for Stock-Based Compensation

Statement of Financial Accounting Standards No. 123, "Accounting for Stock- Based Compensation" (SFAS 123), encourages but does not require that stock awards granted subsequent to December 31, 1994, be recognized as compensation expense based on their fair value at the date of grant. Pursuant to SFAS 123, a company may elect to continue to account for stock awards using the intrinsic value method prescribed in Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees" (APB 25), but must disclose pro forma income amounts which would have resulted from recognizing such awards at their fair value. The Company continues to account for stock-based compensation under APB 25 and provides the pro forma footnote disclosures required under SFAS 123 (Note 8).

Comprehensive Income

Statement of Financial Accounting Standards No. 130, "Reporting Comprehensive Income," establishes standards for the reporting and display of comprehensive income and its components in a full set of general purpose financial statements. To date, the Company has not had any transactions that are required to be reported in comprehensive income.

Fair Value of Financial Instruments

The carrying amounts reported in the balance sheets for cash and cash equivalents, accounts receivable, accounts payable, and the line of credit approximate their fair values due to the short-term nature of these financial instruments.

Impairment of Long-Lived Assets

The Company assesses on an ongoing basis the recoverability of long-lived assets, based on estimates of future undiscounted cash flows compared to net book value. If the future undiscounted cash flow estimates were less than net book value, net book value would then be reduced to fair value based on an estimate of discounted cash flow. The Company also evaluates the amortization periods of assets, including goodwill and other intangible assets, to determine whether events or circumstances warrant revised estimates of useful lives.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and the accompanying notes. Actual results could differ from those estimates and such differences may be material to the financial statements.

2. Goodwill

In connection with the purchase of Highwind by ISPNews in January 1999 (See Note 1), the majority of the purchase price was allocated to goodwill as the net assets of Highwind on the date of acquisition had a nominal fair value. The goodwill of $3,054,000 is being amortized on a straight-line basis over 2 years and is reported net of accumulated amortization of $1,527,000 at December 31, 1999 and $1,909,000 at March 31, 2000.

                                                   ==========  ==========

4. Debt Obligations

Convertible Promissory Notes and Warrants

In November and December of 1999, the Company issued convertible promissory notes (the "Notes") for total proceeds of $2,725,000. The Notes bore interest at 6% and were payable, including accrued interest, on April 25, 2000. Under the terms of the Note agreements, if the Company was able to close the sale and issuance of shares in a second round of preferred stock financing by April 25, 2000, the outstanding principal and unpaid accrued interest on the Notes would automatically convert into shares of the second round preferred financing. The conversion price would be equal to the price per share paid by the investors purchasing such shares.

As part of the Note agreements, the Company was also required to issue warrants to purchase Series A preferred shares to the holders of the Notes on the earlier of April 25, 2000 or the closing of a second round of preferred financing.

The Company was unable to close the second round of preferred financing and on May 12, 2000, the principal and unpaid accrued interest was converted into 704,000 shares of the Company's common stock and the warrants were exercised for 82,000 shares of Series A preferred stock.

Line of Credit

The Company has an equipment line of credit at December 31, 1999 for maximum borrowings of $1,700,000 that expires August 2002. As of December 31, 1999, there was $887,000 outstanding under the line of credit and is collateralized by all assets of the Company. The line of credit agreement provides for interest at 9%. Minimum future payments under the line of credit are $404,000, $404,000 and 185,000 for 2000, 2001 and 2002, respectively.

5. Income Taxes

Prior to the formation of bCandid in January of 1999, ISPNews and Highwind both had S corporation tax status for federal and state income tax purposes. For the year ended December 31, 1999, the Company changed its tax status to a taxable C corporation. In accordance with Financial Accounting Standards No. 109, the effect of the change in tax status resulted in the recognition of deferred tax assets and liabilities primarily related to

the current year net operating loss carryforward. However, the Company has placed a valuation allowance against these otherwise recognizable deferred tax assets due to the uncertainty of realizing the benefit of these favorable tax attributes in the future.

At December 31, 1999, the Company's net operating loss carryforward was approximately $5,399,000, expiring 2019.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.

Significant components of the Company's deferred tax assets and liabilities as of December 31 are as follows:

                                                                  1999

6. Commitments

The Company leases office space under an agreement expiring in 2001. The office lease requires payment of real estate taxes and maintenance in addition to the minimum rental payments.

Minimum future rental payments under the noncancelable operating lease for the remaining lease term are as follows:

2000.............................................................. $105,000
2001..............................................................   44,000
                                                                   --------
                                                                   $149,000

Total rent expense was $73,000 in 1999.

7. Shareholders' Equity

Initial Issuance of Shares

On January 8, 1999, the Company issued 2,999,994 shares for all of the issued and outstanding common stock of ISPNews. Additionally, the Company issued 1,070,000 shares for $1,070,000. In exchange for 100% of the common stock of Highwind common stock, the sole shareholder received 2,004,627 shares of the Company, $1,007,000, and Company's promissory note for $353,000. Approximately $61,000 was paid on the promissory note with the remaining $92,000 recorded as an adjustment to goodwill. The remaining $200,000 was converted into Series A convertible preferred stock.

Series A Convertible Preferred Stock

On April 8, 1999, the Company sold an aggregate of 1,900,000 shares of Series A convertible preferred stock ("Series A") at $2.00 per share, resulting in net proceeds of $3,798,000. Additionally, a note payable to shareholder in the amount of $200,000 was converted into 100,000 shares of Series A. The Series A may, at the option of the holder, be converted at any time into fully-paid and non-assessable shares of Common Stock. Each share of Series A is entitled to share equally with the holders of common shares as to dividends, if declared, and the preferred shareholders have the same voting rights (on an as-converted basis) as the common shareholders. In the event of liquidation, the preferred shareholders have preferential rights to liquidation payments.

Warrants Issued

In connection with entering into an equipment line of credit (see Note 4), the Company issued 25,500 and 12,750 warrants to purchase Series A convertible preferred stock at exercise prices of $2.00 and $1.00, respectively. The warrants are immediately exercisable and expire 10 years from the date of grant. The fair value of the warrants granted was determined to be approximately $20,000 using the minimum value option pricing model. In May 2000, the warrants were exercised.

Common Stock Issued for Notes Receivable

During December 1999, the Company issued 610,970 shares of common stock upon exercise of stock options in exchange for notes receivable of $1,038,000. The notes receivable are full recourse notes, bear interest at 6.02%, and are due on December 29, 2004, including accrued interest. The notes receivable were classified as a reduction of shareholders' equity.

8. Stock Options

The 1999 Equity Incentive Plan provides for the granting of nonqualified and incentive stock options to directors, employees and consultants of the Company. The Board of Directors is authorized to administer the Plan and establish the stock option terms, including the grant price and vesting period. The plan allows for the grant of options for 1,500,000 shares of common stock. As of December 31, 1999, the Company had 123,000 shares of common stock available for future grant under its stock option plan

Stock options typically vest over a four-year period and expire ten years from the date of grant. Vested incentive stock options are exercisable during continued employment or generally within 90 days of terminating employment. Vested nonqualified stock options are exercisable until expiration.

The following table summarizes the Company's stock option activity:

bCANDID CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

(Information at March 31, 2000 and for the three months ended March 31, 2000 and March 31, 1999 is unaudited)

As of December 31, 1999 and March 31, 2000, stock options to purchase common stock of 50,000 and 158,866, respectively, were exercisable. The weighted- average remaining contractual life of options outstanding was 9.08 years at December 31, 1999.

In computing the impact of SFAS 123, a weighted average fair value of $.38 for 1999 stock option grants was estimated at the date of grant using the minimum value option pricing model with the following assumptions: risk-free interest rate of 5.88%, a weighted-average expected life of the options of 3 years and no assumed dividend yield.

For purposes of pro forma disclosures, the estimated fair value of the options is expensed over the vesting period. If the Company elected to recognize compensation cost based on the fair value at the date of grant for options awarded under the Plan as prescribed by SFAS No. 123, the pro forma amounts of the Company's net loss for the years ended 1999 and 1998 would have been as follows:

                                                               December 31
                                                                  1999
                                                               -----------
Net loss--as reported......................................... $6,682,000
Net loss--pro forma........................................... $6,873,000

The pro forma effect on net loss for 1999 is not representative of the pro forma effect on net income in future years because compensation expense in future years will reflect the amortization of a larger number of stock options granted in several succeeding years.

9. Subsequent Events

In March 2000, the Company sold one of its product lines to an outside party for $1,000,000 proceeds which resulted in a gain of $848,000.

In connection with the grant of certain stock options to purchase common stock to employees during March 2000, the Company recorded deferred compensation of $745,000 for the aggregate difference between the exercise prices of the options at their dates of grant and the fair value of the common stock. Such amount is being amortized over the vesting period of the related stock options. Amortization expense recognized for the three months ended March 31, 2000 was $3,000.

On June 14, 2000, Software.com acquired all of the issued and outstanding capital stock of the Company and assumed all of the outstanding warrants and stock options in exchange for Software.com common stock valued at $65,400,000.

Immediately prior to the acquisition of the Company by Software.com on June 14, 2000, bCandid spun-off its service portion of the business. As a result, Software.com acquired the remaining business of bCandid representing its core software development operations.

The following unaudited pro forma information is presented as if the spin- off had occurred on January 1, 1999.

HIGHWIND SOFTWARE, INC.

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 1998

(1) Business and Summary of Significant Accounting Policies

(a) Business and Basis of Financial Statement Presentation

Highwind Software, Inc., a Massachusetts corporation, (the Company) develops and markets software for enterprise-based internet discussions.

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ significantly from those estimates.

(b) Cash and Cash Equivalents

For purposes of the statement of cash flows, the Company considers all cash and investments with maturities of three months or less at the date of purchase to be cash equivalents.

(c) Furniture, Fixtures and Equipment

Furniture, fixtures and equipment are recorded at cost. Costs of maintenance and repairs are charged to operations as incurred. Depreciation is calculated using an accelerated method over the estimated useful lives of the assets, which range from 3 to 5 years.

(d) Fair Value of Financial Instruments

The Company's financial instruments consist primarily of cash and cash equivalents, trade accounts receivable, accounts payable, and accrued liabilities, which carrying values approximate fair values based on their short-term nature.

(e) Impairment of Long-Lived Assets and Assets to be Disposed Of

In accordance with Statement on Financial Accounting Standards No. 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of, the Company reviews long-lived assets and certain identifiable intangibles for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used in operations is generally measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is equal to the amount by which the carrying amounts of the assets exceed their fair values. Assets to be disposed of are reported at the lower of the carrying amount or fair value, less costs to sell. No asset impairment was recognized in 1998.

(f) Revenue Recognition

In accordance with the provisions of Statement of Position 97-2, Software Revenue Recognition (SOP 97-2), the Company recognizes software license revenue when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable and collectibility is probable, based on the terms of the license agreement. In addition, SOP 97-2 requires that revenue recognized from software arrangements be allocated to each multiple element of the arrangement based on the relative fair values of

F-139

NOTES TO FINANCIAL STATEMENTS--(Continued)

DECEMBER 31, 1998

each element. The Company generally sells software licenses with one year maintenance agreements. As the Company does not have objective evidence of the relative fair values of the software and maintenance, revenue for software sales is recognized over the one year maintenance period.

(g) Income Taxes

The Company has elected S Corporation status for income tax purposes and the results of operations of the Company are included in the individual income tax returns of the stockholders. Accordingly, no provision for income taxes has been included in the accompanying financial statements. However, pro forma information has been included in the accompanying statement of operations to reflect a pro forma adjustment for income tax expense as if the Company had been a separate taxable entity subject to federal and state income taxes for 1998.

(2) Furniture, Fixtures and Equipment

Furniture, fixtures and equipment consist of the following at December 31, 1998:

Office and computer equipment and purchased software............. $    147
Furniture and fixtures...........................................   42,480
                                                                  --------

ARTICLE 2.

Effects of the Merger on the Capital Stock of Software.com; Exchange of Certificates

Section 2.1 Effect on Software.com Capital Stock.

As of the Effective Time of the Merger, by virtue of the Merger and without any action on the part of the holders of any shares of common stock, par value $0.001 per share, of Software.com ("Software.com Common Stock") or any shares of common stock of Merger Sub:

(a) Conversion of Software.com Common Stock.

Each issued and outstanding share of Software.com Common Stock (other than any shares of Software.com Common Stock to be canceled pursuant to Section 2.1(c) hereof) shall be converted into the right to receive 1.6105 (the "Exchange Ratio") fully paid and nonassessable shares of common stock, par value $0.001 per share, of Phone ("Phone Common Stock"). As of the Effective Time, all such shares of Software.com Common Stock shall no longer be outstanding and shall automatically be canceled and retired and shall cease to exist. As of the Effective Time, each certificate theretofore representing shares of Software.com Common Stock, without any action on the part of Phone, Software.com or the holder thereof, shall be deemed to represent that number of shares of Phone Common Stock determined by multiplying the shares of Software.com Common Stock represented thereby by the Exchange Ratio. Each holder of a certificate representing any shares of Software.com Common Stock shall cease to have any rights with respect thereto, except the right to receive, upon the surrender of any such certificates, certificates representing the shares of Phone Common Stock to be issued or paid in consideration therefor upon surrender of such certificate in accordance with
Section 2.2 hereof without interest.

(b) Capital Stock of Merger Sub.

Each issued and outstanding share of common stock, par value $0.01 per share, of Merger Sub shall be converted into one fully paid and nonassessable share of common stock, par value $0.01 per share, of the Surviving Corporation.

(c) Cancellation of Treasury Shares. Each share of Software.com Common Stock held in the treasury of Software.com, or owned by Phone or any direct or indirect subsidiary of Software.com or Phone immediately prior to the Effective Time shall automatically be canceled and retired and shall cease to exist, and no consideration shall be delivered in exchange thereof.

(d) Assumption and Conversion of Software.com Options.

(i) As of the Effective Time, each outstanding option or warrant to purchase Software.com Common Stock (a "Software.com Option") issued under each Software.com Stock Plan (as defined in Section 3.2(c)) shall thereafter entitle the holder thereof to receive, upon the exercise thereof, that number of shares of Phone Common Stock equal to the product of (w) the number of shares of Software.com Common Stock subject to such Software.com Option immediately prior to the Effective Time and (x) the Exchange Ratio, at an exercise price for each full share of Phone Common Stock subject to such Software.com Option equal to (y) the exercise price per share of Software.com Common Stock subject to such Software.com Option divided by (z) the Exchange Ratio, which exercise price per share shall be rounded up to the nearest two-place decimal. The number of shares of Phone Common Stock that may be purchased by a holder upon the exercise of any Software.com Option shall not include any fractional share of Phone Common Stock but shall be rounded, in the case of any Software.com Option other than an "incentive stock option" (within the meaning of section 422 of the Code), up and, in the case of any incentive stock option, down to the nearest whole share, if necessary.

(ii) As of the Effective Time, Phone shall assume in full each Software.com Option and all of the other rights and obligations of Software.com under the Software.com Stock Plans (as defined in Section 3.2(c)) as provided herein. Section 2.1(d)(ii) of the Software.com Disclosure Schedule sets forth a list summarizing

A-3

all Software.com Options under all of the Software.com Stock Plans, including the term and the exercise price of each Software.com Option. The assumption of a Software.com Option by Phone shall not terminate or modify (except as required hereunder) any right of first refusal, right of repurchase, vesting schedule or other restriction on transferability relating to a Software.com Option or the stock issuable upon the exercise thereof. Continuous employment with Software.com shall be credited to an optionee for purposes of determining the number of shares subject to exercise, vesting or repurchase after the Effective Time, and the provisions in the Software.com Stock Plans and/or in any stock option agreement evidencing the terms and conditions of any Software.com Option relating to the exercisability of any Software.com Option upon termination of an optionee's employment or service as a director shall not be deemed triggered until such time as such optionee shall be neither an employee or officer nor serving as a director of Phone or any subsidiary. After such assumption, Phone shall issue, upon any partial or total exercise of any Software.com Option, in lieu of shares of Software.com Common Stock, the number of shares of Phone Common Stock to which the holder of the Software.com Option is entitled pursuant to this Agreement. The assumption by Phone of Software.com Options shall not give holders of such Software.com Options any additional benefits which they did not have immediately prior to the Effective Time. Phone shall file with the Securities and Exchange Commission (the "SEC") as soon as practicable, and in any event within two (2) business days, following the Effective Time a registration statement on Form S-8 under the Securities Act of 1933, as amended (the "Securities Act"), covering, to the extent applicable, the shares of Phone Common Stock to be issued upon the exercise of Software.com Options assumed by Phone. Phone shall use commercially reasonable efforts to qualify as soon as practicable, and in any event within two (2) business days, after the Effective Time under the applicable state securities laws the issuance of the shares of Phone Common Stock to be issued upon exercise of such Software.com Options. Prior to the Effective Time, Software.com shall make such amendments, if any, to the Software.com Stock Plans as shall be necessary to permit such assumption in accordance with this
Section 2.1(d).

(iii) It is the intention of the parties that, to the extent that any Software.com Option constitutes an incentive stock option immediately prior to the Effective Time of the Merger, such Software.com Option shall continue to qualify as an incentive stock option to the maximum extent permitted by section 422 of the Code, and that the assumption of Software.com Options provided by this Section 2.1(d) shall satisfy the conditions of section 424(a) of the Code.

(e) At the Effective Time, Phone shall assume the outstanding offering periods under the Software.com Employee Stock Purchase Plan (the "Software.com ESPP"), and all outstanding rights to purchase shares of Software.com Common Stock under the Software.com ESPP ("Purchase Rights") shall be converted (in accordance with the Exchange Ratio) into rights to purchase shares of Phone Common Stock (with the number of shares rounded down to the nearest whole share and the purchase price as of the offering date for each offering period in effect as of the Effective Time rounded up to the nearest whole cent). All such converted Purchase Rights shall be assumed by Phone, and each offering period in effect under the Software.com ESPP immediately prior to the Effective Time shall be continued in accordance with the terms of the Software.com ESPP until the end of such offering period. The Software.com ESPP shall terminate or be merged into the stock purchase plan sponsored by Phone (the "Phone ESPP") immediately following the exercise of the last assumed Purchase Right, and no additional Purchase Rights shall be granted under the Software.com ESPP following the Effective Time, provided that references to Software.com in the Software.com ESPP and related documents shall mean Phone (except that the purchase price as of the offering date for a relevant period shall be determined with respect to the fair market value of Software.com Common Stock on such date, as adjusted hereby). Phone shall take all corporate action necessary to reserve for issuance a sufficient number of shares of Phone Common Stock for issuance upon exercise of Purchase Rights under the Software.com ESPP assumed in accordance with this Section 2.1(e). Phone agrees that, from and after the Effective Time, Software.com employees may participate in the Phone ESPP, subject to the terms and conditions of the Phone ESPP; provided, however, that Phone shall amend the Phone ESPP to provide for a special offering period that permits Software.com employees the ability to immediately participate in the Phone ESPP after the Effective Time, and that service with Software.com shall be treated as service with Phone for determining eligibility of Software.com's employees under the Phone ESPP.

Section 2.2 Exchange of Shares and Certificates.

(a) Exchange Agent. As of the Effective Time of the Merger, Phone shall deposit with U.S. Stock Transfer Corporation or such other bank, trust company or nationally recognized shareholder services provider as may be designated by Phone (the "Exchange Agent"), for the benefit of the holders of shares of Software.com Common Stock, for exchange in accordance with this Article 2, through the Exchange Agent, certificates representing the shares of Phone Common Stock (such shares of Phone Common Stock, together with any dividends or distributions with respect thereto with a record date after the Effective Time, and any cash payable in lieu of any fractional shares of Phone Common Stock, being hereinafter referred to as the "Exchange Fund") issuable pursuant to Section 2.1 hereof in exchange for outstanding shares of Software.com Common Stock.

(b) Exchange Procedures. As soon as reasonably practicable after the Effective Time, the Exchange Agent shall mail to each holder of record of a certificate or certificates which immediately prior to the Effective Time represented outstanding shares of Software.com Common Stock (the "Certificates") whose shares were converted into shares of Phone Common Stock pursuant to Section 2.1 hereof, (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as Phone may reasonably specify), and (ii) instructions for use in effecting the surrender of the Certificates in exchange for certificates representing shares of Phone Common Stock. Upon surrender of a Certificate for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by Phone, together with such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificate shall be entitled to receive in exchange therefor a certificate representing that number of whole shares of Phone Common Stock which such holder has the right to receive pursuant to the provisions of this Article 2, and the Certificate so surrendered shall forthwith be canceled. In the event of a transfer of ownership of Software.com Common Stock which is not registered in the transfer records of Software.com, a certificate representing the proper number of shares of Phone Common Stock may be issued to a person other than the person in whose name the Certificate so surrendered is registered, if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such issuance shall pay any transfer or other taxes required by reason of the issuance of shares of Phone Common Stock to a person other than the registered holder of such Certificate or establish to the satisfaction of Phone that such tax has been paid or is not applicable. No interest shall be paid or shall accrue on any cash payable in lieu of any fractional shares of Phone Common Stock.

(c) Distributions with Respect to Unexchanged Shares. No dividends or other distributions with respect to Phone Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of Phone Common Stock represented thereby, and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to Section 2.2(e) hereof, until the surrender of such Certificate in accordance with this Article 2. Subject to the effect of applicable laws, following surrender of any such Certificate, there shall be paid to the holder of the certificate representing whole shares of Phone Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender, the amount of any cash payable in lieu of a fractional share of Phone Common Stock to which such holder is entitled pursuant to Section 2.2(e) and the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such whole shares of Phone Common Stock, and
(ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and a payment date subsequent to such surrender payable with respect to such whole shares of Phone Common Stock.

(d) No Further Ownership Rights in Software.com Common Stock. All shares of Phone Common Stock issued upon the surrender for exchange of Certificates in accordance with the terms of this Article 2 (including any cash paid pursuant to Section 2.2(c) or 2.2(e) hereof) shall be deemed to have been issued (and paid) in full satisfaction of all rights pertaining to the shares of Software.com Common Stock theretofore represented by such Certificates, subject, however, to the obligation of the Surviving Corporation, as applicable, to pay any dividends or make any other distributions with a record date prior to the Effective Time which may have been declared or

A-5

made by Software.com on such shares of Software.com Common Stock in accordance with the terms of this Agreement and which remain unpaid at the Effective Time, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Software.com Common Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation or the Exchange Agent for any reason, they shall be canceled and exchanged as provided in this Article 2, except as otherwise provided by law.

(e) Fractional Shares.

(i) No certificates representing fractional shares of Phone Common Stock shall be issued upon the surrender for exchange of Certificates, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a stockholder of Phone.

(ii) Notwithstanding any other provision of this Agreement, each holder of shares of Software.com Common Stock converted pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of Phone Common Stock (after taking into account all Certificates delivered by such holder) shall receive, in lieu thereof, cash (without interest) in an amount equal to (i) such fraction multiplied by (ii) the average of the closing price of a share of Software.com Common Stock for the ten (10) most recent trading days that Software.com Common Stock has traded ending on the trading day immediately prior to the Effective Time, as reported on the Nasdaq National Market.

(f) Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the holders of the Certificates for six (6) months after the Effective Time shall be delivered to Phone, upon demand, and any holders of the Certificates who have not theretofore complied with this Article 2 shall thereafter look only to Phone for payment of their claim for Phone Common Stock, any cash in lieu of fractional shares of Phone Common Stock and any dividends or distributions with respect to Phone Common Stock.

(g) No Liability. None of Phone, Merger Sub, Software.com or the Exchange Agent shall be liable to any person in respect of any shares of Phone Common Stock (or dividends or distributions with respect thereto) or cash from the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If any Certificates shall not have been surrendered prior to seven (7) years after the Effective Time, or immediately prior to such earlier date on which any shares of Phone Common Stock, any cash in lieu of fractional shares of Phone Common Stock or any dividends or distributions with respect to Phone Common Stock in respect of such Certificate would otherwise escheat to or become the property of any Governmental Entity, any such shares, cash, dividends or distributions in respect of such Certificate shall, to the extent permitted by applicable law, become the property of the Surviving Corporation, free and clear of all claims or interest of any person previously entitled thereto.

(h) Investment of Exchange Fund. The Exchange Agent shall invest any cash included in the Exchange Fund, as directed by Phone, on a daily basis. Any interest and other income resulting from such investments shall be paid to Phone.

Section 2.3 Certain Adjustments.

If between the date hereof and the Effective Time, the outstanding shares of Software.com Common Stock or Phone Common Stock shall be changed into a different number of shares by reason of any reclassification, recapitalization, split-up, combination or exchange of shares, or any dividend payable in stock or other securities shall be declared thereon with a record date within such period, the Exchange Ratio shall be adjusted accordingly to provide to the holders of Software.com Common Stock the same economic effect as contemplated by this Agreement prior to such reclassification, recapitalization, split-up, combination, exchange, or dividend.

Each of Phone and its subsidiaries is duly qualified or licensed to do business and is in good standing (with respect to jurisdictions which recognize such concept) in each jurisdiction in which the nature of its business or the ownership, leasing or operation of its properties makes such qualification or licensing necessary, except for those jurisdictions where the failure to be so qualified or licensed or to be in good standing individually or in the aggregate would not have a material adverse effect on Phone.

This Agreement and the Option Agreements have been duly executed and delivered by Phone and Merger Sub and, assuming the due authorization, execution and delivery of each agreement to which they are parties by Software.com constitutes (or will constitute, as the case may be) the legal, valid and binding obligation of Phone and Merger Sub, enforceable against Phone and Merger Sub in accordance with their terms. The execution and delivery of this Agreement does not, and the execution and delivery of the Option Agreements and the consummation of the transactions contemplated hereby and thereby and compliance with the provisions of this Agreement and the Option Agreements will not, conflict with, or result in any violation of, or default (with or without notice or lapse of time, or both) under, or give rise to a right of termination, cancellation or acceleration of any obligation or loss of a benefit under, or result in the creation of any Lien upon any of the properties or assets of Phone or any of its subsidiaries or in any restriction on the conduct of Phone's business or operations under, (i) the Phone Certificate or the by-laws of Phone or the comparable organizational documents of any of its subsidiaries, (ii) any loan or credit agreement, note, bond, mortgage, indenture, trust document, lease, or other agreement,

A-8

No collective bargaining agreement is being negotiated or renegotiated by Phone or any of its subsidiaries. As of the date of this Agreement, there is no labor dispute, strike or work stoppage against Phone or any of its subsidiaries pending or, to the knowledge of Phone, threatened which may interfere with the respective business activities of Phone or any of its subsidiaries, except where such dispute, strike or work stoppage individually or in the aggregate would not have a material adverse effect on Phone.

(vii) To the knowledge of Phone, no material oral or written representation or commitment with respect to any aspect of any Phone Benefit Plan has been made to employees of Phone or any Phone subsidiaries by an authorized Phone employee prior to the Closing Date that is not materially in accordance with the written or otherwise preexisting terms and provisions of such Phone Benefit Plans in effect immediately prior to the Closing Date.

Neither Phone nor any Phone

A-12

subsidiary is obligated to make reimbursement or gross-up payments to any person in respect to excess parachute payments.

(k) Taxes.

(i) Each of Phone and its subsidiaries has filed all material Tax Returns required to be filed by it (taking into account all applicable extensions) with the appropriate Tax Authority and all such returns are true, complete, and correct in all material respects, or requests for extensions to file such returns have been timely filed, granted, and have not expired, except to the extent that such failures to file, to be complete, true, or correct, or to have extensions granted that remain in effect individually or in the aggregate would not have a material adverse effect on Phone. Phone and each of its subsidiaries has paid (or Phone has paid or caused to be paid on its behalf) all Taxes shown as due on such returns, and the most recent financial statements contained in the Phone Filed SEC Documents reflect an adequate reserve in accordance with GAAP for all Taxes payable by Phone and its subsidiaries for all taxable periods and portions thereof accrued through the date of such financial statements.

A-22

For purposes of this

A-30

Agreement "Alternative Transaction" means any of (i) a transaction or series of transactions pursuant to which any person (or group of persons) other than Software.com and its subsidiaries and other than Phone and its subsidiaries (a "Third Party") acquires or would acquire, directly or indirectly, beneficial ownership (as defined in Rule 13d-3 under the Exchange Act) of more than twenty percent (20%) of the outstanding shares of Software.com or Phone, as the case may be, whether from Software.com or Phone or pursuant to a tender offer or exchange offer or otherwise, (ii) any acquisition or proposed acquisition of Software.com or any of its significant subsidiaries or Phone or any of its significant subsidiaries, as the case may be, by a merger or other business combination (including any so-called "merger of equals" and whether or not Software.com or any of its significant subsidiaries or Phone or any of its significant subsidiaries, as the case may be, is the entity surviving any such merger or business combination) or (iii) any other transaction pursuant to which any Third Party acquires or would acquire, directly or indirectly, control of assets (including for this purpose the outstanding equity securities of subsidiaries of Software.com or Phone, as the case may be, and any entity surviving any merger or combination including any of them) of Software.com or any of its subsidiaries or Phone or any of its subsidiaries, as the case may be, for consideration equal to twenty percent (20%) or more of the fair market value of all of the outstanding shares of Software.com Common Stock or all of the outstanding shares of Phone Common Stock, as the case may be, on the date prior to the date hereof.

(b) Neither the Board of Directors of Phone nor any committee thereof shall

For purposes of this Agreement, a "Phone Superior Proposal" means any proposal (on its most recently amended or modified terms, if amended or modified) made by a Third Party to enter into an Alternative Transaction which the Board of Directors of Phone determines in its good faith judgment (after consultation with a financial advisor of nationally recognized reputation) to be more favorable to Phone's stockholders than the Merger taking into account all relevant factors (including whether, in the good faith judgment of the Board of Directors of Phone, after consultation with a financial advisor of nationally recognized reputation, the third party is reasonably able to finance the transaction). Notwithstanding any other provision of this Agreement, Phone shall submit this Agreement to its stockholders whether or not the Board of Directors of Phone makes a Phone Subsequent Determination.

(c) In addition to the obligations of Phone set forth in paragraphs (a) and
(b) of this Section 4.2, and in any event within one (1) business day, Phone shall promptly advise Software.com orally and in writing of any request for information or of any proposal in connection with an Alternative Transaction, the material terms and conditions of such request or proposal and the identity of the person making such request or proposal.

(a) Software.com shall not, nor shall it permit any of its subsidiaries to, nor shall it authorize or permit any of its officers, directors or employees or any investment banker, financial advisor, attorney, accountant or other representative retained by it or any of its subsidiaries to, directly or indirectly through another person, (i) solicit, initiate or encourage (including by way of furnishing information), or take any other action designed to facilitate, any inquiries or the making of any proposal the consummation of which would constitute an Alternative Transaction or (ii) participate in any discussions or negotiations regarding any Alternative Transaction; provided, however, that if, at any time prior to the adoption of this Agreement by the holders of Software.com Common Stock, the Board of Directors of Software.com determines in good faith, after consultation with outside counsel, that the failure to provide such information or participate in such negotiations or discussions would result in a reasonable possibility that the Board of Directors of Software.com breach its fiduciary duties to Software.com's stockholders under applicable law, Software.com may, in response to any such proposal that was not solicited by it or which did not otherwise result from a breach of this Section 4.3(a), and subject to compliance with Section 4.3(c), (x) furnish information with respect to Software.com and its subsidiaries to any person pursuant to a customary confidentiality agreement containing terms as to confidentiality no less restrictive than the Confidentiality Agreement, as amended pursuant to Section 8.6 hereof, and (y) participate in negotiations regarding such proposal.

For purposes of this Agreement, a "Software.com Superior Proposal" means any proposal (on its most recently amended or modified terms, if amended or modified) made by a Third Party enter into an Alternative Transaction on terms which the Board of Directors of Software.com determines in its good faith judgment (after consultation with a financial advisor of nationally recognized reputation) to be more favorable to Software.com's stockholders than the Merger taking into account all relevant factors (including whether, in the good faith judgment of the Board of Directors of Software.com, after consultation with a financial advisor of nationally recognized reputation, the third party is reasonably able to finance the transaction). Notwithstanding any other provision of this Agreement, Software.com shall submit this Agreement to its stockholders whether or not the Board of Directors of Software.com make a Software.com Subsequent Determination.

(c) In addition to the obligations of Software.com set forth in paragraphs
(a) and (b) of this Section 4.3, and in any event within one (1) business day, Software.com shall promptly advise Phone orally and in writing of any request for information or of any proposal in connection with an Alternative Transaction, the material terms

(i) taking and disclosing to its stockholders a position contemplated by Rule 14d-9 or Rule 14e-2(a) promulgated under the Exchange Act or (ii) from making any disclosure to its stockholders if, in the good faith judgment of the Board of Directors of Software.com, after consultation with outside counsel, failure so to disclose would be inconsistent with its fiduciary duties to Software.com's stockholders under applicable law.

(b) In connection with and without limiting the foregoing, Phone and Software.com shall (i) take all action necessary to ensure that no state takeover statute or similar statute or regulation is or becomes applicable to this Agreement, the Option Agreements, or any of the transactions contemplated hereby and thereby and (ii) if any state takeover statute or similar statute or regulation becomes applicable to such agreements or transactions, take all action necessary to ensure that such transactions may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise to minimize the effect of such statute or regulation on the Merger and the other transactions contemplated by this Agreement.

Section 5.5 Indemnification, Exculpation and Insurance.

Phone agrees that at all times after the Effective Time, it shall indemnify, and shall cause the Surviving Corporation to indemnify, each person who is now, or has been at any time prior to the date hereof, a director or officer of Software.com, any of its subsidiaries or affiliates, or of any of its successors and assigns (individually an "Indemnified Party" and collectively the "Indemnified Parties"), to the same extent and in the same manner as is now provided in the certificate of incorporation or by-laws of Software.com or otherwise in effect at the Effective Time (pursuant to an indemnification agreement or otherwise), with respect to any claim, liability, loss, damage, cost or expense (whenever asserted or claimed) based in whole or in part on, or arising in whole or in part out of, any matter existing or occurring at or prior to the Effective Time. Phone shall, or shall cause the Surviving Corporation to, maintain in effect for not less than six (6) years after the Effective Time the current policies of directors' and officers' liability insurance maintained by Software.com on the date hereof (provided that Phone or the Surviving Corporation may substitute therefor policies having at least the same coverage and containing terms and conditions which are no less advantageous to the persons currently covered by such policies as insured) with respect to matters existing or occurring at or prior to the Effective Time. Without limiting the foregoing, in the event any Indemnified Party becomes involved in any capacity in any action, proceeding or investigation based in whole or in part on, or arising in whole or in part out of, any matter, including the transactions contemplated hereby, existing or occurring at or prior to the Effective Time, then, following the Effective Time, to the extent permitted by law Phone shall, or shall cause the Surviving Corporation to, periodically advance to such Indemnified Party its legal and other expenses (including the cost of any investigation and preparation incurred in connection therewith), subject to the provision by such Indemnified Party of an undertaking to reimburse the amounts so advanced in the event of a final determination by a court of competent jurisdiction that such Indemnified Party is not entitled thereto. Promptly after receipt by an Indemnified Party of notice of the assertion (an "Assertion") of any claim or the commencement of any action against him or her in respect to which indemnity or reimbursement may be sought against Phone, the Surviving Corporation or a subsidiary of Phone ("Indemnitors") hereunder, such Indemnified Party shall notify any Indemnitor in writing of the Assertion, but the failure to so notify any Indemnitor shall not relieve any Indemnitor of any liability it may have to such Indemnified Party hereunder except to the extent such failure shall have materially prejudiced Indemnitor in defending against such Assertion. Indemnitors shall be entitled to participate in and, to the extent Indemnitors (A) elect by written notice to such Indemnified Party within thirty (30) days after receipt by any Indemnitor of notice of such Assertion and (B) acknowledge in writing their obligation to indemnify the Indemnified Parties in connection with such Assertion, to assume the defense of such Assertion, at their own expense, with counsel chosen by Indemnitors and reasonably satisfactory to such Indemnified Party. Notwithstanding that Indemnitors shall have elected by such written notice to assume the defense of any Assertion, such Indemnified Party shall have the right to participate in the investigation and defense thereof, with separate counsel chosen by such Indemnified Party, but in such event the fees and expenses of such counsel shall be paid by such Indemnified Party, unless, in the opinion of such separate counsel, (i) such Indemnified Party has available to him one or more defenses to such Assertion that may not be available to the Indemnitors,

A-35

(ii) there is otherwise a conflict of interest between the Indemnified Party, on the one hand, and the Indemnitors, on the other hand, or (iii) the Indemnitors fail to vigorously pursue the defense of the asserted claim. No Indemnified Party shall settle any Assertion without the prior written consent of Phone, nor shall any Indemnitor settle any Assertion without either (i) the written consent of all Indemnified Parties against whom such Assertion was made, or (ii) obtaining a general release from the party making the Assertion for all Indemnified Parties as a condition of such settlement. The provisions of this Section 5.5 are intended for the benefit of, and shall be enforceable by, the respective Indemnified Parties. The provisions of this Section 5.5 are not intended to constitute insurance. To the extent that any policy of insurance shall provide all or any part of the indemnity owed to the Indemnified Parties, or any of them, hereunder, the Indemnitors shall be relieved of their obligation with regard thereto. No acceptance by an Indemnified Party of any defense from any third party with respect to an Assertion shall be deemed to constitute a waiver by such Indemnified Party of its rights under this Section 5.5 or to receive the full measure of the indemnity provided for hereby.

Section 5.6 Fees and Expenses.

Except as set forth in this Section 5.6 and in Section 7.2, all fees and expenses incurred in connection with the Merger, this Agreement, the Option Agreements and the transactions contemplated by this Agreement and the Option Agreements shall be paid by the party incurring such fees or expenses, whether or not the Merger are consummated, except that each of Software.com and Phone shall bear and pay one-half of the costs and expenses (other than the fees and expenses of each party's attorneys and accountants which shall be paid by the party incurring such expenses) incurred by Phone, Merger Sub, or Software.com in connection with (i) the filing, printing and mailing of the Form S-4 and the Joint Proxy Statement (including SEC filing fees) and (ii) the filings of the premerger notification and report forms under the HSR Act (including filing fees).

(f) Each Termination Fee payable under Section 7.2(c)(3) shall be paid in cash and shares of Software.com Common Stock, in such combination as Software.com may elect (provided that the cash component must be at least Forty Million Dollars ($40,000,000.00)) with an aggregate value (for all purposes of this Section 7.2(e), such shares of Software.com Common Stock to be valued at a price per share equal to the average closing price per share of Software.com Common Stock for the five (5) most recent trading days that Software.com Common Stock has traded ending on the trading day immediately prior to the termination date, as reported on the Nasdaq National Market) equal to the Termination Fee, payable no later than three (3) business days following the delivery of notice of termination to the other party. If Software.com satisfies its obligation to pay the Termination Fee in part by issuing shares of Software.com Common Stock (the "Software.com Termination Fee Shares"), then Phone shall be entitled to registration rights with respect to such shares as described in the Software.com Stock Option Agreement (treating Software.com Termination Fee Shares for all purposes of Section 7 of the Software.com Stock Option Agreement as if they were Option Shares (as defined in the Software.com Stock Option Agreement)).

(g) Software.com and Phone agree that the agreements contained in Sections 7.2(b) and (c) above are an integral part of the transaction contemplated by this Agreement and constitute liquidated damages and not a penalty. If one party fails to promptly pay to the other any fee due under such Sections 7.2(b) and (c), the defaulting party shall pay the costs and expenses (including legal fees and expenses) in connection with any action, including the filing of any lawsuit or other legal action, taken to collect payment.

This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto and duly approved by the parties' respective Boards of Directors or a duly designated committee thereof.

Any agreement on the part of a party to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party. Any extension or waiver given in compliance with this Section 7.4 or failure to insist on strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

STOCK OPTION AGREEMENT

(PHONE.COM, INC. SHARES)




STOCK OPTION AGREEMENT

(PHONE.COM, INC. SHARES)

THIS STOCK OPTION AGREEMENT (this "AGREEMENT"), dated August 8, 2000, between Phone.com, Inc., a Delaware corporation ("Issuer"), and Software.com, Inc., a Delaware corporation ("Grantee").

WITNESSETH:

WHEREAS, Grantee and Issuer have entered into an Agreement and Plan of Merger, dated as of August 8, 2000 (the "Merger Agreement"), which provides, among other things, for the merger of Merger Sub with and into Grantee with Grantee continuing as the surviving corporation upon the terms and subject to the conditions set forth in the Merger Agreement (capitalized terms used herein without definition shall have the respective meanings specified in the Merger Agreement); and

WHEREAS, as a condition to Grantee's entering into the Merger Agreement and in consideration therefor, Issuer has agreed to grant Grantee the Option (as hereinafter defined).

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements set forth herein and in the Merger Agreement, and intending to be legally bound hereby, the parties hereto agree as follows:

1. Grant of Option. Issuer hereby grants to Grantee an unconditional, irrevocable option (the "Option") to purchase, subject to the terms hereof, sixteen million five hundred sixteen thousand four hundred ninety-five (16,516,495) shares of fully paid and nonassessable common stock of the Issuer, par value $.001 per share ("Common Stock"), equal to and in no event exceeding nineteen and nine-tenths percent (19.9%) of the shares of Common Stock outstanding as of July 31, 2000 the date hereof, at a purchase price of $78.0625 per share of Common Stock as adjusted in accordance with the provisions of Section 6 of this Agreement (such price, as adjusted if applicable, the "Option Price").

2. Exercise of Option.

(a) Grantee may exercise the Option, in whole or part, and from time to time, if, but only if, a Triggering Event (as hereinafter defined) shall have occurred prior to the occurrence of an Option Termination Event (as hereinafter defined), provided that Grantee shall have sent the written notice of such exercise (as provided in subsection (e) of this Section 2) on or prior to the last date of the six (6)-month period following such Triggering Event (the "Option Expiration Date").

(b) The term "Option Termination Event" shall mean the first day after the earliest to occur of the following dates: (i) the date on which the Effective Time of the Merger occurs; (ii) the last date of the twelve (12) month period beginning on the date of termination of the Merger Agreement pursuant to
Section 7.1(b)(ii); provided, that such termination has given rise to the right of Grantee to receive payment of Software.com Expenses pursuant to
Section 7.2(b)(1) of the Merger Agreement; provided, that subsequent to such termination, if an event occurs that gives rise to the obligation of Issuer to pay the Termination Fee pursuant to Section 7.2(b)(2) of the Merger Agreement, then the last date of the six (6) month period beginning on the date of actual payment of the Termination Fee by Issuer to Grantee pursuant to Section 7.2(b)(2) of the Merger Agreement; (iii) the date of termination of the Merger Agreement by either party pursuant to the provisions of any section of the Merger Agreement other than Sections 7.1(b)(ii) (other than as provided in clause (ii) above); provided, that such termination occurs prior to the occurrence of a Triggering Event; and (iv) the last date of the six (6) month period beginning on the date of the first occurrence of a Triggering Event; provided, however, that if the Option cannot be exercised as of any such date by reason of any applicable judgment, decree, law, regulation or order (each, an "Impediment"), or by reason of the waiting period under the HSR Act, then the Option Termination

B-1

Event shall be delayed until the date which is thirty (30) days after such Impediment has been removed or such waiting period has expired.

(c) Triggering Event. The term "Triggering Event" shall mean any termination of the Merger Agreement which entitles Grantee to receive payment of the Termination Fee from Issuer pursuant to Section 7.2 of the Merger Agreement.

(d) Notice of Triggering Event. Issuer shall notify Grantee promptly in writing of the occurrence of any Triggering Event, and in any event within twenty-four (24) hours, it being understood that the giving of such notice by Issuer shall not be a condition to the right of Grantee to exercise the Option or for a Triggering Event to have occurred.

(e) Notice of Exercise; Closing. In the event Grantee is entitled to and wishes to exercise the Option, it shall send to Issuer a written notice (the date of which being herein referred to as the "Notice Date") specifying (i) the total number of shares it will purchase pursuant to such exercise and (ii) a place and date which shall be a business day not earlier than three (3) business days nor later than sixty (60) business days from the Notice Date for the closing of such purchase (the "Closing Date"); provided, that if the closing of the purchase and sale pursuant to the Option (the "Closing") cannot be consummated, in the reasonable opinion of Grantee, by reason of any applicable judgment, decree, order, law or regulation, the period of time that otherwise would run pursuant to this sentence shall run instead from the date on which such restriction on consummation has expired or been terminated; and provided further, without limiting the foregoing, that if, in the reasonable opinion of Grantee, prior notification to or approval of any regulatory agency is required in connection with such purchase, Grantee shall promptly file the required notice or application for approval and shall expeditiously process the same and the period of time that otherwise would run pursuant to this sentence shall run instead from the date on which any required notification periods have expired or been terminated or such approvals have been obtained and any requisite waiting period or periods shall have passed. Any exercise of the Option shall be deemed to occur on the Closing Date relating thereto.

(f) Purchase Price. At the Closing referred to in subsection (e) of this
Section 2, Grantee shall pay to Issuer the aggregate purchase price for the shares of Common Stock purchased pursuant to the exercise of the Option in immediately available funds by wire transfer to a bank account designated by Issuer, provided that failure or refusal of Issuer to designate such a bank account shall not preclude Grantee from exercising the Option.

(g) Issuance of Common Stock. At such Closing, simultaneously with the delivery of immediately available funds as provided in subsection (f) of this
Section 2, Issuer shall deliver to Grantee a certificate or certificates representing the number of shares of Common Stock purchased by the Grantee and, if the Option should be exercised in part only, a new Option evidencing the rights of Grantee thereof to purchase the balance of the shares purchasable hereunder, and the Grantee shall deliver to Issuer this Agreement and a letter agreeing that Grantee will not offer to sell or otherwise dispose of such shares in violation of applicable law or the provisions of this Agreement.

(h) Legend. Certificates for Common Stock delivered at a Closing hereunder may be endorsed with a restrictive legend that shall read substantially as follows:

"THE TRANSFER AND VOTING OF THE SHARES REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO CERTAIN PROVISIONS OF AN AGREEMENT BETWEEN THE REGISTERED HOLDER HEREOF AND ISSUER AND TO RESALE RESTRICTIONS ARISING UNDER THE SECURITIES ACT OF 1933, AS AMENDED. A COPY OF SUCH AGREEMENT IS ON FILE AT THE PRINCIPAL OFFICE OF ISSUER AND WILL BE PROVIDED TO THE HOLDER HEREOF WITHOUT CHARGE UPON RECEIPT BY ISSUER OF A WRITTEN REQUEST THEREFOR."

It is understood and agreed that: (i) the reference to the resale restrictions of the Securities Act of 1933, as amended (the "Securities Act"), in the above legend shall be removed by delivery of substitute certificate(s)

B-2

without such reference if Grantee shall have delivered to Issuer a copy of a letter from the staff of the SEC, or an opinion of counsel, in form and substance reasonably satisfactory to Issuer, to the effect that such legend is not required for purposes of the Securities Act; (ii) the reference to the provisions of this Agreement in the above legend shall be removed by delivery of substitute certificate(s) without such reference if the shares have been sold or transferred in compliance with the provisions of this Agreement and under circumstances that do not require the retention of such reference; and
(iii) the legend shall be removed in its entirety if the conditions in the preceding clauses (i) and (ii) and both satisfied. In addition, such certificates shall bear any other legend as may be required by law.

(i) Record Holder; Expenses. Upon the Closing, Grantee shall be deemed to be the holder of record of the shares of Common Stock issuable upon such exercise, notwithstanding that the stock transfer books of Issuer shall then be closed or that certificates representing such shares of Common Stock shall not then be actually delivered to Grantee or the Issuer shall have failed or refused to designate the bank account described in subsection (f) of this
Section 2. Issuer shall pay all expenses, and any and all United States federal, state and local taxes and other charges that may be payable in connection with the preparation, issuance and delivery of stock certificates under this Section 2 in the name of Grantee or its assignee, transferee or designee.

3. Conditions to Delivery of Option Shares. The obligation of Issuer to deliver Option Shares upon any exercise of the Option is subject to the satisfaction of the following conditions:

(a) All waiting periods, if any, under the HSR Act applicable to the issuance of Option Shares hereunder shall have expired or been terminated; and

(b) There shall be no preliminary or permanent injunction or other order issued by any court of competent jurisdiction preventing or prohibiting such exercise of the Option or the delivery of the Option Shares in respect of such exercise.

4. Reservation of Shares. Issuer agrees: (i) that it shall at all times maintain, free from preemptive rights, sufficient authorized but unissued or treasury shares of Common Stock (and other securities issuable pursuant to
Section 6) so that the Option may be exercised without additional authorization of Common Stock (or such other securities) after giving effect to all other options, warrants, convertible securities and other rights to purchase Common Stock (or such other securities); (ii) that it will not, by charter amendment or through reorganization, consolidation, merger, dissolution or sale of assets, or by any other voluntary act avoid or seek to avoid the observance or performance of any of the covenants, stipulations or conditions to be observed or performed hereunder by Issuer; (iii) promptly to take all action as may from time to time be required (including without limitation complying with all premerger notification, reporting and waiting periods in the HSR Act and the rules and regulations thereunder) in order to permit Grantee to exercise the Option and the Issuer duly and effectively to issue shares of Common Stock pursuant hereto; and (iv) promptly to take all action provided herein to protect the rights of Grantee against dilution.

5. Lost Options. Upon receipt by Issuer of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Agreement, and (in the case of loss, theft or destruction) of reasonably satisfactory indemnification, and upon surrender and cancellation of this Agreement, if mutilated, Issuer will execute and deliver a new Agreement of like tenor and date.

6. Adjustment Upon Changes in Capitalization. The number of shares of Common Stock purchasable upon the exercise of the Option shall be subject to adjustment from time to time as provided in this Section 6.

(a) In the event that any additional shares of Common Stock are issued or otherwise become outstanding after the date hereof (other than by reason of subsection (b) of this Section 6), the number of shares of Common Stock subject to the Option shall be increased so that, after such issuance of additional shares, such number of shares then remaining subject to the Option, together with shares theretofore issued pursuant to the Option, equals nineteen and nine-tenths percent (19.9%) of the number of such shares of Common Stock then issued and outstanding.

B-3

(b) In the event of any change in Common Stock by reason of stock dividends, other dividends on the Common Stock payable in securities or other property (other than regular cash dividends), stock splits, merger, recapitalization, combinations, subdivisions, conversions, exchanges of shares or other similar transactions, then the type and number of shares of Common Stock purchasable upon exercise hereof shall be appropriately adjusted, and proper provision will be made in the agreements governing such transaction so that Grantee shall receive upon exercise of the Option and payment of the aggregate Option Price hereunder the number and class of shares or other securities or property that Grantee would have received in respect of Common Stock if the Option had been exercised in full immediately prior to such event, or the record date therefor, as applicable.

(c) Whenever the number of shares of outstanding Common Stock changes after the date hereof as a result of the events described in clause (b) hereof (but not the events described in clause (a) hereof), the Option Price shall be adjusted by multiplying the Option Price by a fraction the numerator of which shall be equal to the aggregate number of shares of Common Stock purchasable prior to the adjustment and the denominator of which shall be equal to the aggregate number of shares of Common Stock purchasable immediately after the adjustment.

(d) No adjustment made in accordance with this Section 6 shall constitute or be deemed a waiver of any breach of any of Issuer's representations, warranties, covenants, agreements or obligations contained in the Merger Agreement.

(e) If the Issuer satisfies a portion of its obligation to pay Grantee a termination fee as permitted by Section 7.2 of the Merger Agreement by issuing to Grantee shares of Common Stock (the "Termination Fee Shares"), then the number of shares of Common Stock subject to the Option (including those Option Shares which may have already been exercised) will be adjusted so that the sum of the number of shares of Common Stock subject to the Option and the number of Termination Fee Shares equals nineteen and nine- tenths percent (19.9%) of the number of shares of Common Stock then issued and outstanding, without giving effect to any Option Shares or Termination Fee Shares.

7. Registration Rights.

(a) As used in this Agreement, "Registrable Securities" means each of the Option Shares issued to Grantee hereunder and any other securities issued in exchange for, or issued as dividends or otherwise on or in respect of, any of such Option Shares.

(b) At any time or from time to time within three (3) years of the first Closing, Grantee may make a written request to Issuer for registration under and in accordance with the provisions of the Securities Act with respect to all or any part of the Registrable Securities (a "Demand Registration"). A Demand Registration may be, at the option of Grantee, a shelf registration or a registration involving an underwritten offering. As soon as reasonably practicable after Grantee's request for a Demand Registration, Issuer shall file one or more registration statements on any appropriate form with respect to all of the Registrable Securities requested to be so registered; provided that Issuer will not be required to file any such registration statement during any period of time (not to exceed sixty (60) days after such request in the case of clause (i) below or ninety (90) days in the case of clauses (ii) or (iii) below) when (i) Issuer is in possession of material non-public information which it reasonably believes would be detrimental to be disclosed at such time, (ii) Issuer is required under the Securities Act to include audited financial statements for any period in such registration statement that are not yet available for inclusion therein, or (iii) Issuer determines, in its reasonable judgment, that such registration would interfere with any financing, acquisition or other material transaction involving Issuer or any of its affiliates. Issuer shall use its best efforts to have the Demand Registration declared effective as soon as reasonably practicable after such filing and to keep the Demand Registration continuously effective for a period of at least sixty (60) days following the date on which the Demand Registration is declared effective, in the case of an underwritten offering, or at least one hundred twenty (120) days following the date on which the Demand Registration is declared effective, in the case of a shelf registration; provided that, if for any reason the effectiveness of any Demand Registration is suspended, the required period of effectiveness shall be extended by the aggregate

B-4

number of days of each such suspension; and provided, further, that the effectiveness of any Demand Registration may be terminated if and when all of the Registrable Securities covered thereby shall have been sold. Grantee shall be entitled to two (2) Demand Registrations: provided, that only requests relating to a registration statement that has become effective under the Securities Act shall be counted for purposes of determining the number of Demand Registrations made. If any Demand Registration involves an underwritten offering, (i) Issuer shall have the right to select the managing underwriter, which shall be reasonably acceptable to Grantee and (ii) Issuer shall enter into an underwriting agreement in customary form.

(c) If at any time within two (2) years of the first Closing, Issuer proposes to file a registration statement under the Securities Act with respect to any shares of any class of its equity securities to be sold for the account of Issuer (other than a registration statement on Form S-4 or Form S-8 or any successor form), and the registration form to be used may be used for the registration of Registrable Securities, then Issuer shall in each case give written notice of such proposed filing to Grantee at least twenty (20) days before the anticipated filing date, and Grantee shall have the right to include in such registration such number of Registrable Securities as Grantee may request (such request to be made by written notice to Issuer within fifteen (15) days following Grantee's receipt from Issuer of such notice of proposed filing) (an "Incidental Registration"). Issuer shall use its commercially reasonable efforts to cause the managing underwriter of any proposed underwritten offering to permit Grantee to include in such offering all Registrable Securities requested by Grantee to be included in the registration for such offering on the same terms and conditions as any similar securities of Issuer included therein. Notwithstanding the foregoing, if the managing underwriter of such offering advises Grantee that, in the reasonable opinion of such underwriter, the amount of Registrable Securities which Grantee requests to be included in such offering would materially and adversely affect the success of such offering, then the amount of Registrable Securities to be offered shall be reduced to the extent necessary to reduce the total amount of securities to be included in such offering to the amount recommended by such underwriter; provided that if the amount of Registrable Securities shall be so reduced, Issuer shall include in such offering (i) first all shares proposed to be included therein by the Issuer and (ii) second the shares requested to be included therein by Grantee pro rata with the shares intended to be included therein by any other stockholder of the Issuer. Participation by Grantee in any Incidental registration shall not affect the obligation of the Company to effect Demand Registrations under this Section
4.1. The issuer may withdraw any registration under the Securities Act that gives rise to an Incidental Registration without consent of Grantee.

(d) In the event that Registrable Securities are included in a "piggyback" registration statement pursuant to Section 7(c) hereof, Grantee agrees not to effect any public sale or distribution of the issue being registered or a similar security of Issuer, or any securities convertible into or exchangeable or exercisable for such securities, including a sale pursuant to Rule 144 under the Securities Act, during the ten (10) business days prior to, and during the ninety (90)-day period beginning on, the effective date of such registration statement (except as part of such registration), if and to the extent timely notified in writing by Issuer, in the case of a non-underwritten public offering, or by the managing underwriter, in the case of an underwritten public offering. In the event that Grantee requests a Demand Registration or if Registrable Securities are included in a "piggyback" registration pursuant to Section 7(c) hereof, Issuer agrees not to effect any public sale or distribution of the issue being registered or a similar security of Issuer, or any securities convertible into or exchangeable or exercisable for such securities, during the period from such request until ninety (90) days after the effective date of such registration statement (except as part of such registration or pursuant to a registration of securities on Form S-4 or Form S-8 or any successor form).

(e) Notwithstanding anything to the contrary contained herein, in the event that Grantee requests a Demand Registration or a "piggyback" registration of Registrable Securities pursuant to Section 7(b) or 7(c) hereof, respectively, Issuer shall have the right to purchase all, but not less than all, of the Registrable Securities requested to be so registered, upon the terms and subject to the conditions set forth in this Section 7(e). If Issuer wishes to exercise such purchase right, then within two (2) business days following receipt of a request for a Demand Registration or a "piggyback" registration, Issuer shall send a written notice (a "Repurchase Notice") to Grantee specifying that Issuer wishes to exercise such purchase right, a date for the closing of such purchase,

B-5

which shall not be more than five (5) business days after delivery of such Repurchase Notice, and a place for the closing of such purchase (a "Repurchase Closing"). Upon delivery of a Repurchase Notice subject to applicable Delaware law, a binding agreement shall be deemed to exist between Grantee and Issuer providing for the purchase by Issuer of the Registrable Securities requested to be registered by Grantee, upon the terms and subject to the conditions set forth in this Section 7(e). The purchase price per share or other unit of Registrable Securities (the "Repurchase Price") shall equal the average per share or per unit closing price as quoted on the Nasdaq (or if not then quoted thereon, on such other exchange or quotation system on which the Registrable Securities are quoted) for the period of five (5) trading days ending on the trading day immediately prior to the day on which Grantee requests a Demand Registration or a "piggyback" registration of the Registrable Securities which Issuer subsequently elects to purchase. Grantee's obligation to deliver any Registrable Securities at a Repurchase Closing shall be subject to the condition that, at such Repurchase Closing, Issuer shall have delivered to Grantee a certificate signed on behalf of Issuer by Issuer's chief executive officer and chief financial officer, which certificate shall be satisfactory in form and substance to Grantee, to the effect that the purchase by Issuer of such Registrable Securities (i) is permitted under applicable Delaware corporate law and under the fraudulent conveyance provisions of the federal bankruptcy code and (ii) does not violate any material agreement to which Issuer or any of its subsidiaries is a party or by which any of their properties or assets is bound. At any Repurchase Closing, Issuer shall pay to Grantee the aggregate Repurchase Price for the Registrable Securities being purchased by wire transfer of immediately available funds or by delivering to Grantee a certified or bank check payable to or on the order of Grantee in an amount equal to such aggregate Repurchase Price, and Grantee will surrender to Issuer a certificate or certificates evidencing such Registrable Securities. A purchase of Registrable Securities by Issuer pursuant to this Section 7(e) shall be considered a Demand Registration for purposes of Section 7(b) hereof.

(f) The registrations effected under this Section 7 shall be effected at Issuer's expense except for underwriting commissions allocable to the Registrable Securities. Issuer shall indemnify and hold harmless Grantee, its affiliates and controlling persons and their respective officers, directors, agents and representatives from and against any and all losses, claims, damages, liabilities and expenses (including, without limitation, all out-of- pocket expenses, investigation expenses, expenses incurred with respect to any judgment and fees and disbursements of counsel and accountants) arising out of or based upon any statements contained in, or omissions or alleged omissions from, each registration statement (and related prospectus) filed pursuant to this Section 7; provided, however, that Issuer shall not be liable in any such case to Grantee or any affiliate or controlling person of Grantee or any of their respective officers, directors, agents or representatives to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon an untrue statement or omission or alleged omission made in such registration statement or prospectus in reliance upon, and in conformity with, written information furnished to Issuer specifically for use in the preparation thereof by Grantee such affiliate, controlling person, officer, director, agent or representative, as the case may be.

8. Repurchase of Option and Option Shares.

(a) At the request of and upon notice by Grantee (the "Put Notice") at any time during the period during which the Option is exercisable pursuant to
Section 2 (the "Purchase Period"), the Issuer (or any successor entity thereof) will purchase from Grantee all or any portion of the Option, to the extent not previously exercised, at the price set forth in subparagraph (i) below, and all or any portion of the Option Shares, if any, acquired by Grantee pursuant thereto, at the price set forth in subparagraph (ii) below:

(i) the difference between the "Market/Tender Offer Price" for the Common Stock as of the date Grantee gives notice of its intent to exercise its rights under this Section 7(a) (defined as the higher of (A) the highest price per share offered as of such date pursuant to any Acquisition Proposal which was made prior to such date and (B) the average closing sale price of Common Stock then on the Nasdaq National Market during the five
(5) trading days ending on the trading day immediately preceding such date) and the Exercise Price, multiplied by the number of Common Stock purchasable pursuant to the Option, but only if the Market/Tender Offer Price is greater than the Exercise Price. For purposes of determining the highest price offered pursuant to any Acquisition Proposal which involves consideration other than cash, the value

B-6

of such consideration will be equal to the higher of (x) if securities of the same class of the proponent as such considerations are traded on any national securities exchange or by any registered securities association, a value based on the closing sale price or asked price for such securities on their principal trading market on such date and (y) the value ascribed to such consideration by the proponent of such Acquisition Proposal, or if no such value is ascribed, a value determined in good faith by the Board of Directors of the Issuer.

(ii) The Market/Tender Offer Price multiplied by the number of shares of Common Stock so purchased.

(c) The Grantee has taken, and will in the future take, all steps necessary to irrevocably exempt the transactions contemplated by this Agreement from any applicable state takeover law and from any applicable charter or contractual provision containing change of control or anti- takeover provisions.

12. Assignment of Option by Grantee. Neither of the parties hereto may assign any of its rights or obligations under this Option Agreement or the Option created hereunder to any other person, without the express written consent of the other party.

13. Limitation of Grantee Profit.

(a) Notwithstanding any other provision of this Agreement, in no event shall the Grantee's Total Profit (as hereinafter defined) exceed Two Hundred Thirty Million Four Hundred Fifty-Four Thousand Five Hundred Forty-Five dollars ($230,454,545.00) (the "Profit Cap") and, if it otherwise would exceed such amount, the Grantee, at its sole election, shall either (i) reduce the number of shares of Common Stock subject to this Option, (ii) deliver to the Issuer for cancellation Option Shares previously purchased by, or Termination Fee Shares (or other securities into which such Termination Fee Shares are converted or exchanged) to Grantee (valued, for the purposes of this Section 12(a) at the average closing sales price per share of Common Stock (or if there is no sale on such date then the average between the closing bid and ask prices on any such day) as reported by the Nasdaq National Market for the five
(5) consecutive trading days preceding the day on which the Grantee's Total Profit exceeds the Profit Cap, (iii) pay cash to the Issuer, (iv) reduce the number of Termination Fee Shares to be paid by the Grantee or (v) any combination thereof, so that Grantee's actually realized Total Profit shall not exceed the Profit Cap after taking into account the foregoing actions.

(b) As used herein, the term "Total Profit" shall mean the amount (before taxes) of the following: (a) the aggregate amount of (i) (x) the net cash amounts received by Grantee pursuant to the sale of Option Shares or Termination Fee Shares (or any other securities into which such Option Shares or Termination Fee Shares are converted or exchanged) to any unaffiliated party or to Issuer pursuant to this Agreement, less (y) the Grantee's purchase price of such Option Shares or other securities, (ii) any amounts received by Grantee on the transfer of the Option (or any portion thereof), if permitted hereunder, and (iii) the amount received by Grantee pursuant to Section 7.2 of the Merger Agreement; minus (b) the amount of cash theretofore paid to the Issuer pursuant to this Section 12 plus the value of the Option Shares or Termination Fee Shares or other securities theretofore delivered to the Issuer for cancellation pursuant to this Section 12.

B-8

(c) Notwithstanding any other provision of this Agreement, nothing in this Agreement shall affect the ability of Grantee to receive nor relieve Issuer's obligation to pay a fee pursuant to Section 7.2 of the Merger Agreement; provided that if Total Profit received by Grantee would exceed the Profit Cap following the receipt of such fee, Grantee shall be obligated to comply with the terms of Section 12(a) within five (5) days of the later of (i) the date of receipt of such fee and (ii) the date of receipt of the net cash by Grantee pursuant to the sale of Option Shares or Termination Fee Shares (or, any other securities into which such Option Shares or Termination Fee Shares are converted or exchanged) pursuant to this Agreement.

(d) Notwithstanding any other provision of this Agreement, the Option may not be exercised for a number of Option Shares that would, as of the Notice Date, result in a Notional Total Profit (as defined below) of more than the Profit Cap; provided; however, that Grantee may indicate in its notice of exercise that Grantee is taking any of the actions described in subsection (a) hereof so as to reduce the Notional Total Profit to not more than the Profit Cap and preserve its rights to exercise the Option for the resulting number of Option Shares. "Notional Total Profit" shall mean, with respect to any number of Option Shares as to which the Grantee may propose to exercise the Option, the Total Profit determined as of the Notice Date assuming that the Option was exercised on such date for such number of Option Shares and assuming such Option Shares, together with all other Option Shares held by the Grantee and its affiliates as of such date, were sold for cash at the closing sales price for Common Stock as of the close of business on the preceding trading day.

(e) For purposes of Section 11(a) and clause (iii) of Section 11(b), the value of any Option Shares delivered by Grantee to the Issuer shall be the average closing sales price per share of Common Stock (or if there is no sale on such date then the average between the closing bid and ask prices on any such day) as reported by the Nasdaq National Market for the five (5) consecutive trading days preceding the day the Grantee's Total Profit exceeds the Profit Cap.

14. Application for Regulatory Approval. Each of Grantee and Issuer will use its commercially reasonable efforts to make all filings with, and to obtain consents of, all third parties and governmental authorities necessary to the consummation of the transactions contemplated by this Agreement, including without limitation making application to list the shares of Common Stock issuable hereunder on the Nasdaq National Market upon official notice of issuance.

15. Specific Performance. The parties hereto acknowledge that damages would be an inadequate remedy for a breach of this Agreement by either party hereto and that the obligations of the parties hereto shall be enforceable by either party hereto through injunctive or other equitable relief.

16. Separability of Provisions. If any term, provision, covenant or restriction contained in this Agreement is held by a court or a federal or state regulatory agency of competent jurisdiction to be invalid, void or unenforceable, the remainder of the terms, provisions and covenants and restrictions contained in this Agreement shall remain in full force and effect, and shall in no way be affected, impaired or invalidated.

17. Notices. All notices, claims, demands and other communications hereunder shall be deemed to have been duly given or made when delivered in person, by overnight courier or by facsimile at the respective addresses of the parties set forth in the Merger Agreement.

18. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws thereof.

19. Counterparts. This Agreement may be executed in two or more counterparts, each of which will be deemed to be an original, but all of which shall constitute one and the same agreement.

20. Expenses. Except as otherwise expressly provided herein or in the Merger Agreement, each of the parties hereto shall bear and pay all costs and expenses incurred by it or on its behalf in connection with the

B-9

transactions contemplated hereunder, including fees and expenses of its own financial consultants, investment bankers, accountants and counsel.

21. Entire Agreement. Except as otherwise expressly provided herein or in the Merger Agreement, this Agreement contains the entire agreement between the parties with respect to the transactions contemplated hereunder and supersedes all prior arrangements or understandings with respect thereof, written or oral. The terms and conditions of this Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and permitted assigns.

Any provision of this Agreement may be waived only in writing at any time by the party that is entitled to the benefits of such provision. This Agreement may not be modified, amended, altered or supplemented except upon the execution and delivery of a written agreement executed by the parties hereto.

22. Further Assurances. In the event of any exercise of the Option by Grantee, Issuer and Grantee shall execute and deliver all other documents and instruments and take all other action that may be reasonably necessary in order to consummate the transactions provided for by such exercise. Nothing contained in this Agreement shall be deemed to authorize Issuer or Grantee to breach any provision of the Merger Agreement.

STOCK OPTION AGREEMENT

(SOFTWARE.COM, INC. SHARES)




STOCK OPTION AGREEMENT

(SOFTWARE.COM, INC. SHARES)

THIS STOCK OPTION AGREEMENT (this "AGREEMENT"), dated August 8, 2000, between Software.com, Inc., a Delaware corporation ("Issuer"), and Phone.com, Inc., a Delaware corporation ("Grantee"),

WITNESSETH:

WHEREAS, Grantee and Issuer have entered into an Agreement and Plan of Merger, dated as of August 8, 2000 (the "Merger Agreement"), which provides, among other things, for the merger of Merger Sub with and into Issuer with Issuer continuing as the surviving corporation upon the terms and subject to the conditions set forth in the Merger Agreement (capitalized terms used herein without definition shall have the respective meanings specified in the Merger Agreement); and

WHEREAS, as a condition to Grantee's entering into the Merger Agreement and in consideration therefor, Issuer has agreed to grant Grantee the Option (as hereinafter defined).

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements set forth herein and in the Merger Agreement, and intending to be legally bound hereby, the parties hereto agree as follows:

1. Grant of Option. Issuer hereby grants to Grantee an unconditional, irrevocable option (the "Option") to purchase, subject to the terms hereof, nine million seven hundred twenty-four thousand four hundred sixty (9,724,460) shares of fully paid and nonassessable common stock of the Issuer, par value $.001 per share ("Common Stock"), equal to and in no event exceeding nineteen and nine-tenths percent (19.9%) of the shares of Common Stock outstanding as of the date hereof, at a purchase price of $125.7197 per share of Common Stock as adjusted in accordance with the provisions of Section 6 of this Agreement (such price, as adjusted if applicable, the "Option Price").

2. Exercise of Option.

(a) Grantee may exercise the Option, in whole or part, and from time to time, if, but only if, a Triggering Event (as hereinafter defined) shall have occurred prior to the occurrence of an Option Termination Event (as hereinafter defined), provided that Grantee shall have sent the written notice of such exercise (as provided in subsection (e) of this Section 2) on or prior to the last date of the six (6)-month period following such Triggering Event (the "Option Expiration Date").

(b) The term "Option Termination Event" shall mean the first day after the earliest to occur of the following dates: (i) the date on which the Effective Time of the Merger occurs; (ii) the last date of the twelve (12) month period beginning on the date of termination of the Merger Agreement pursuant to
Section 7.1(b)(iii); provided, that such termination has given rise to the right of Grantee to receive payment of Software.com Expenses pursuant to
Section 7.2(c)(1) of the Merger Agreement; provided, that subsequent to such termination, if an event occurs that gives rise to the obligation of Issuer to pay the Termination Fee pursuant to Section 7.2(c)(2) of the Merger Agreement, then the last date of the six (6) month period beginning on the date of actual payment of the Termination Fee by Issuer to Grantee pursuant to Section 7.2(c)(2) of the Merger Agreement; (iii) the date of termination of the Merger Agreement by either party pursuant to the provisions of any section of the Merger Agreement other than Sections 7.1(b)(iii) (other than as provided in clause (ii) above); provided, that such termination occurs prior to the occurrence of a Triggering Event; and (iv) the last date of the six (6) month period beginning on the date of the first occurrence of a Triggering Event; provided, however, that if the Option cannot be exercised as of any such date by reason of any applicable judgment, decree, law, regulation or order

C-1

(each, an "Impediment"), or by reason of the waiting period under the HSR Act, then the Option Termination Event shall be delayed until the date which is thirty (30) days after such Impediment has been removed or such waiting period has expired.

(c) Triggering Event. The term "Triggering Event" shall mean any termination of the Merger Agreement which entitles Grantee to receive payment of the Termination Fee from Issuer pursuant to Section 7.2 of the Merger Agreement.

(d) Notice of Triggering Event. Issuer shall notify Grantee promptly in writing of the occurrence of any Triggering Event, and in any event within twenty-four (24) hours, it being understood that the giving of such notice by Issuer shall not be a condition to the right of Grantee to exercise the Option or for a Triggering Event to have occurred.

(e) Notice of Exercise; Closing. In the event Grantee is entitled to and wishes to exercise the Option, it shall send to Issuer a written notice (the date of which being herein referred to as the "Notice Date") specifying (i) the total number of shares it will purchase pursuant to such exercise and (ii) a place and date which shall be a business day not earlier than three (3) business days nor later than sixty (60) business days from the Notice Date for the closing of such purchase (the "Closing Date"); provided, that if the closing of the purchase and sale pursuant to the Option (the "Closing") cannot be consummated, in the reasonable opinion of Grantee, by reason of any applicable judgment, decree, order, law or regulation, the period of time that otherwise would run pursuant to this sentence shall run instead from the date on which such restriction on consummation has expired or been terminated; and provided further, without limiting the foregoing, that if, in the reasonable opinion of Grantee, prior notification to or approval of any regulatory agency is required in connection with such purchase, Grantee shall promptly file the required notice or application for approval and shall expeditiously process the same and the period of time that otherwise would run pursuant to this sentence shall run instead from the date on which any required notification periods have expired or been terminated or such approvals have been obtained and any requisite waiting period or periods shall have passed. Any exercise of the Option shall be deemed to occur on the Closing Date relating thereto.

(f) Purchase Price. At the Closing referred to in subsection (e) of this
Section 2, Grantee shall pay to Issuer the aggregate purchase price for the shares of Common Stock purchased pursuant to the exercise of the Option in immediately available funds by wire transfer to a bank account designated by Issuer, provided that failure or refusal of Issuer to designate such a bank account shall not preclude Grantee from exercising the Option.

(g) Issuance of Common Stock. At such Closing, simultaneously with the delivery of immediately available funds as provided in subsection (f) of this
Section 2, Issuer shall deliver to Grantee a certificate or certificates representing the number of shares of Common Stock purchased by the Grantee and, if the Option should be exercised in part only, a new Option evidencing the rights of Grantee thereof to purchase the balance of the shares purchasable hereunder, and the Grantee shall deliver to Issuer this Agreement and a letter agreeing that Grantee will not offer to sell or otherwise dispose of such shares in violation of applicable law or the provisions of this Agreement.

(h) Legend. Certificates for Common Stock delivered at a Closing hereunder may be endorsed with a restrictive legend that shall read substantially as follows:

"THE TRANSFER AND VOTING OF THE SHARES REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO CERTAIN PROVISIONS OF AN AGREEMENT BETWEEN THE REGISTERED HOLDER HEREOF AND ISSUER AND TO RESALE RESTRICTIONS ARISING UNDER THE SECURITIES ACT OF 1933, AS AMENDED. A COPY OF SUCH AGREEMENT IS ON FILE AT THE PRINCIPAL OFFICE OF ISSUER AND WILL BE PROVIDED TO THE HOLDER HEREOF WITHOUT CHARGE UPON RECEIPT BY ISSUER OF A WRITTEN REQUEST THEREFOR."

C-2

It is understood and agreed that: (i) the reference to the resale restrictions of the Securities Act of 1933, as amended (the "Securities Act"), in the above legend shall be removed by delivery of substitute certificate(s) without such reference if Grantee shall have delivered to Issuer a copy of a letter from the staff of the SEC, or an opinion of counsel, in form and substance reasonably satisfactory to Issuer, to the effect that such legend is not required for purposes of the Securities Act; (ii) the reference to the provisions of this Agreement in the above legend shall be removed by delivery of substitute certificate(s) without such reference if the shares have been sold or transferred in compliance with the provisions of this Agreement and under circumstances that do not require the retention of such reference; and
(iii) the legend shall be removed in its entirety if the conditions in the preceding clauses (i) and (ii) and both satisfied. In addition, such certificates shall bear any other legend as may be required by law.

(i) Record Holder; Expenses. Upon the Closing, Grantee shall be deemed to be the holder of record of the shares of Common Stock issuable upon such exercise, notwithstanding that the stock transfer books of Issuer shall then be closed or that certificates representing such shares of Common Stock shall not then be actually delivered to Grantee or the Issuer shall have failed or refused to designate the bank account described in subsection (f) of this Section 2. Issuer shall pay all expenses, and any and all United States federal, state and local taxes and other charges that may be payable in connection with the preparation, issuance and delivery of stock certificates under this Section 2 in the name of Grantee or its assignee, transferee or designee.

3. Conditions to Delivery of Option Shares. The obligation of Issuer to deliver Option Shares upon any exercise of the Option is subject to the satisfaction of the following conditions:

(a) All waiting periods, if any, under the HSR Act applicable to the issuance of Option Shares hereunder shall have expired or been terminated; and

(b) There shall be no preliminary or permanent injunction or other order issued by any court of competent jurisdiction preventing or prohibiting such exercise of the Option or the delivery of the Option Shares in respect of such exercise.

4. Reservation of Shares. Issuer agrees: (i) that it shall at all times maintain, free from preemptive rights, sufficient authorized but unissued or treasury shares of Common Stock (and other securities issuable pursuant to
Section 6) so that the Option may be exercised without additional authorization of Common Stock (or such other securities) after giving effect to all other options, warrants, convertible securities and other rights to purchase Common Stock (or such other securities); (ii) that it will not, by charter amendment or through reorganization, consolidation, merger, dissolution or sale of assets, or by any other voluntary act avoid or seek to avoid the observance or performance of any of the covenants, stipulations or conditions to be observed or performed hereunder by Issuer; (iii) promptly to take all action as may from time to time be required (including without limitation complying with all premerger notification, reporting and waiting periods in the HSR Act and the rules and regulations thereunder) in order to permit Grantee to exercise the Option and the Issuer duly and effectively to issue shares of Common Stock pursuant hereto; and (iv) promptly to take all action provided herein to protect the rights of Grantee against dilution.

5. Lost Options. Upon receipt by Issuer of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Agreement, and (in the case of loss, theft or destruction) of reasonably satisfactory indemnification, and upon surrender and cancellation of this Agreement, if mutilated, Issuer will execute and deliver a new Agreement of like tenor and date.

6. Adjustment upon Changes in Capitalization. The number of shares of Common Stock purchasable upon the exercise of the Option shall be subject to adjustment from time to time as provided in this Section 6.

(a) In the event that any additional shares of Common Stock are issued or otherwise become outstanding after the date hereof (other than by reason of subsection (b) of this Section 6), the number of shares of Common Stock subject to the Option shall be increased so that, after such issuance of additional

C-3

shares, such number of shares then remaining subject to the Option, together with shares theretofore issued pursuant to the Option, equals nineteen and nine-tenths percent (19.9%) of the number of such shares of Common Stock then issued and outstanding.

(b) In the event of any change in Common Stock by reason of stock dividends, other dividends on the Common Stock payable in securities or other property (other than regular cash dividends), stock splits, merger, recapitalization, combinations, subdivisions, conversions, exchanges of shares or other similar transactions, then the type and number of shares of Common Stock purchasable upon exercise hereof shall be appropriately adjusted, and proper provision will be made in the agreements governing such transaction so that Grantee shall receive upon exercise of the Option and payment of the aggregate Option Price hereunder the number and class of shares or other securities or property that Grantee would have received in respect of Common Stock if the Option had been exercised in full immediately prior to such event, or the record date therefor, as applicable.

(c) Whenever the number of shares of outstanding Common Stock changes after the date hereof as a result of the events described in clause (b) hereof (but not the events described in clause (a) hereof), the Option Price shall be adjusted by multiplying the Option Price by a fraction the numerator of which shall be equal to the aggregate number of shares of Common Stock purchasable prior to the adjustment and the denominator of which shall be equal to the aggregate number of shares of Common Stock purchasable immediately after the adjustment.

(d) No adjustment made in accordance with this Section 6 shall constitute or be deemed a waiver of any breach of any of Issuer's representations, warranties, covenants, agreements or obligations contained in the Merger Agreement.

(e) If the Issuer satisfies a portion of its obligation to pay Grantee a termination fee as permitted by Section 7.2 of the Merger Agreement by issuing to Grantee shares of Common Stock (the "Termination Fee Shares"), then the number of shares of Common Stock subject to the Option (including those Option Shares which may have already been exercised) will be adjusted so that the sum of the number of shares of Common Stock subject to the Option and the number of Termination Fee Shares equals nineteen and nine- tenths percent (19.9%) of the number of shares of Common Stock then issued and outstanding, without giving effect to any Option Shares or Termination Fee Shares.

7. Registration Rights.

(a) As used in this Agreement, "Registrable Securities" means each of the Option Shares issued to Grantee hereunder and any other securities issued in exchange for, or issued as dividends or otherwise on or in respect of, any of such Option Shares.

(b) At any time or from time to time within three (3) years of the first Closing, Grantee may make a written request to Issuer for registration under and in accordance with the provisions of the Securities Act with respect to all or any part of the Registrable Securities (a "Demand Registration"). A Demand Registration may be, at the option of Grantee, a shelf registration or a registration involving an underwritten offering. As soon as reasonably practicable after Grantee's request for a Demand Registration, Issuer shall file one or more registration statements on any appropriate form with respect to all of the Registrable Securities requested to be so registered; provided that Issuer will not be required to file any such registration statement during any period of time (not to exceed sixty (60) days after such request in the case of clause (i) below or ninety (90) days in the case of clauses (ii) or (iii) below) when (i) Issuer is in possession of material non-public information which it reasonably believes would be detrimental to be disclosed at such time, (ii) Issuer is required under the Securities Act to include audited financial statements for any period in such registration statement that are not yet available for inclusion therein, or (iii) Issuer determines, in its reasonable judgment, that such registration would interfere with any financing, acquisition or other material transaction involving Issuer or any of its affiliates. Issuer shall use its best efforts to have the Demand Registration declared effective as soon as reasonably practicable after such filing and to keep the Demand Registration continuously effective for a period of at least sixty (60) days following the date on which the Demand Registration is declared effective, in the case of an underwritten

C-4

offering, or at least one hundred twenty (120) days following the date on which the Demand Registration is declared effective, in the case of a shelf registration; provided that, if for any reason the effectiveness of any Demand Registration is suspended, the required period of effectiveness shall be extended by the aggregate number of days of each such suspension; and provided, further, that the effectiveness of any Demand Registration may be terminated if and when all of the Registrable Securities covered thereby shall have been sold. Grantee shall be entitled to two (2) Demand Registrations; provided, that only requests relating to a registration statement that has become effective under the Securities Act shall be counted for purposes of determining the number of Demand Registrations made. If any Demand Registration involves an underwritten offering, (i) Issuer shall have the right to select the managing underwriter, which shall be reasonably acceptable to Grantee and (ii) Issuer shall enter into an underwriting agreement in customary form.

(c) If at any time within two (2) years of the first Closing, Issuer proposes to file a registration statement under the Securities Act with respect to any shares of any class of its equity securities to be sold for the account of Issuer (other than a registration statement on Form S-4 or Form S-8 or any successor form), and the registration form to be used may be used for the registration of Registrable Securities, then Issuer shall in each case give written notice of such proposed filing to Grantee at least twenty (20) days before the anticipated filing date, and Grantee shall have the right to include in such registration such number of Registrable Securities as Grantee may request (such request to be made by written notice to Issuer within fifteen (15) days following Grantee's receipt from Issuer of such notice of proposed filing) (an "Incidental Registration"). Issuer shall use its commercially reasonable efforts to cause the managing underwriter of any proposed underwritten offering to permit Grantee to include in such offering all Registrable Securities requested by Grantee to be included in the registration for such offering on the same terms and conditions as any similar securities of Issuer included therein. Notwithstanding the foregoing, if the managing underwriter of such offering advises Grantee that, in the reasonable opinion of such underwriter, the amount of Registrable Securities which Grantee requests to be included in such offering would materially and adversely affect the success of such offering, then the amount of Registrable Securities to be offered shall be reduced to the extent necessary to reduce the total amount of securities to be included in such offering to the amount recommended by such underwriter; provided that if the amount of Registrable Securities shall be so reduced, Issuer shall include in such offering (i) first all shares proposed to be included therein by the Issuer and (ii) second the shares requested to be included therein by Grantee pro rata with the shares intended to be included therein by any other stockholder of the Issuer. Participation by Grantee in any Incidental registration shall not affect the obligation of the Company to effect Demand Registrations under this Section
4.1. The issuer may withdraw any registration under the Securities Act that gives rise to an Incidental Registration without consent of Grantee.

(d) In the event that Registrable Securities are included in a "piggyback" registration statement pursuant to Section 7(c) hereof, Grantee agrees not to effect any public sale or distribution of the issue being registered or a similar security of Issuer, or any securities convertible into or exchangeable or exercisable for such securities, including a sale pursuant to Rule 144 under the Securities Act, during the ten (10) business days prior to, and during the ninety (90)-day period beginning on, the effective date of such registration statement (except as part of such registration), if and to the extent timely notified in writing by Issuer, in the case of a non-underwritten public offering, or by the managing underwriter, in the case of an underwritten public offering. In the event that Grantee requests a Demand Registration or if Registrable Securities are included in a "piggyback" registration pursuant to Section 7(c) hereof, Issuer agrees not to effect any public sale or distribution of the issue being registered or a similar security of Issuer, or any securities convertible into or exchangeable or exercisable for such securities, during the period from such request until ninety (90) days after the effective date of such registration statement (except as part of such registration or pursuant to a registration of securities on Form S-4 or Form S-8 or any successor form).

(e) Notwithstanding anything to the contrary contained herein, in the event that Grantee requests a Demand Registration or a "piggyback" registration of Registrable Securities pursuant to Section 7(b) or 7(c) hereof, respectively, Issuer shall have the right to purchase all, but not less than all, of the Registrable Securities requested to be so registered, upon the terms and subject to the conditions set forth in this Section 7(e). If Issuer wishes to exercise such purchase right, then within two (2) business days following receipt of a request for a

C-5

Demand Registration or a "piggyback" registration, Issuer shall send a written notice (a "Repurchase Notice") to Grantee specifying that Issuer wishes to exercise such purchase right, a date for the closing of such purchase, which shall not be more than five (5) business days after delivery of such Repurchase Notice, and a place for the closing of such purchase (a "Repurchase Closing"). Upon delivery of a Repurchase Notice subject to applicable Delaware law, a binding agreement shall be deemed to exist between Grantee and Issuer providing for the purchase by Issuer of the Registrable Securities requested to be registered by Grantee, upon the terms and subject to the conditions set forth in this Section 7(e). The purchase price per share or other unit of Registrable Securities (the "Repurchase Price") shall equal the average per share or per unit closing price as quoted on the Nasdaq (or if not then quoted thereon, on such other exchange or quotation system on which the Registrable Securities are quoted) for the period of five (5) trading days ending on the trading day immediately prior to the day on which Grantee requests a Demand Registration or a "piggyback" registration of the Registrable Securities which Issuer subsequently elects to purchase. Grantee's obligation to deliver any Registrable Securities at a Repurchase Closing shall be subject to the condition that, at such Repurchase Closing, Issuer shall have delivered to Grantee a certificate signed on behalf of Issuer by Issuer's chief executive officer and chief financial officer, which certificate shall be satisfactory in form and substance to Grantee, to the effect that the purchase by Issuer of such Registrable Securities (i) is permitted under applicable Delaware corporate law and under the fraudulent conveyance provisions of the federal bankruptcy code and (ii) does not violate any material agreement to which Issuer or any of its subsidiaries is a party or by which any of their properties or assets is bound. At any Repurchase Closing, Issuer shall pay to Grantee the aggregate Repurchase Price for the Registrable Securities being purchased by wire transfer of immediately available funds or by delivering to Grantee a certified or bank check payable to or on the order of Grantee in an amount equal to such aggregate Repurchase Price, and Grantee will surrender to Issuer a certificate or certificates evidencing such Registrable Securities. A purchase of Registrable Securities by Issuer pursuant to this Section 7(e) shall be considered a Demand Registration for purposes of Section 7(b) hereof.

(f) The registrations effected under this Section 7 shall be effected at Issuer's expense except for underwriting commissions allocable to the Registrable Securities. Issuer shall indemnify and hold harmless Grantee, its affiliates and controlling persons and their respective officers, directors, agents and representatives from and against any and all losses, claims, damages, liabilities and expenses (including, without limitation, all out-of- pocket expenses, investigation expenses, expenses incurred with respect to any judgment and fees and disbursements of counsel and accountants) arising out of or based upon any statements contained in, or omissions or alleged omissions from, each registration statement (and related prospectus) filed pursuant to this Section 7; provided, however, that Issuer shall not be liable in any such case to Grantee or any affiliate or controlling person of Grantee or any of their respective officers, directors, agents or representatives to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon an untrue statement or omission or alleged omission made in such registration statement or prospectus in reliance upon, and in conformity with, written information furnished to Issuer specifically for use in the preparation thereof by Grantee such affiliate, controlling person, officer, director, agent or representative, as the case may be.

8. Repurchase of Option and Option Shares.

(a) At the request of and upon notice by Grantee (the "Put Notice") at any time during the period during which the Option is exercisable pursuant to
Section 2 (the "Purchase Period"), the Issuer (or any successor entity thereof) will purchase from Grantee all or any portion of the Option, to the extent not previously exercised, at the price set forth in subparagraph (i) below, and all or any portion of the Option Shares, if any, acquired by Grantee pursuant thereto, at the price set forth in subparagraph (ii) below:

(i) The difference between the "Market/Tender Offer Price" for the Common Stock as of the date Grantee gives notice of its intent to exercise its rights under this Section 7(a) (defined as the higher of (A) the highest price per share offered as of such date pursuant to any Acquisition Proposal which was made prior to such date and (B) the average closing sale price of Common Stock then on the Nasdaq National Market during the five
(5) trading days ending on the trading day immediately preceding such

C-6

date) and the Exercise Price, multiplied by the number of Common Stock purchasable pursuant to the Option, but only if the Market/Tender Offer Price is greater than the Exercise Price. For purposes of determining the highest price offered pursuant to any Acquisition Proposal which involves consideration other than cash, the value of such consideration will be equal to the higher of (x) if securities of the same class of the proponent as such considerations are traded on any national securities exchange or by any registered securities association, a value based on the closing sale price or asked price for such securities on their principal trading market on such date and (y) the value ascribed to such consideration by the proponent of such Acquisition Proposal, or if no such value is ascribed, a value determined in good faith by the Board of Directors of the Issuer.

(ii) The Market/Tender Offer Price multiplied by the number of shares of Common Stock so purchased.

(d) The Issuer has taken, and will in the future take, all steps necessary to irrevocably exempt the transactions contemplated by this Agreement from any applicable state takeover law and from any applicable charter or contractual provision containing change of control or anti-takeover provisions.

(c) The Grantee has taken, and will in the future take, all steps necessary to irrevocably exempt the transactions contemplated by this Agreement from any applicable state takeover law and from any applicable charter or contractual provision containing change of control or anti- takeover provisions.

11. Grantee Compliance. Grantee shall acquire the Option Shares for investment purposes only and not with a view to any distribution thereof in violation of the Securities Act, and shall not sell any Option Shares purchased pursuant to this Agreement except in compliance with the Securities Act.

12. Assignment of Option by Grantee. Neither of the parties hereto may assign any of its rights or obligations under this Option Agreement or the Option created hereunder to any other person, without the express written consent of the other party.

13. Limitation of Grantee Profit.

(a) Notwithstanding any other provision of this Agreement, in no event shall the Grantee's Total Profit (as hereinafter defined) exceed Two Hundred Thirty Million Four Hundred Fifty-Four Thousand Five Hundred Forty-Five dollars ($230,454,545.00) (the "Profit Cap") and, if it otherwise would exceed such amount, the Grantee, at its sole election, shall either (i) reduce the number of shares of Common Stock subject to this Option, (ii) deliver to the Issuer for cancellation Option Shares previously purchased by, or Termination Fee Shares (or other securities into which such Termination Fee Shares are converted or exchanged) to Grantee (valued, for the purposes of this Section 12(a) at the average closing sales price per share of Common Stock (or if there is no sale on such date then the average between the closing bid and ask prices on any such day) as reported by the Nasdaq National Market for the five
(5) consecutive trading days preceding the day on which the Grantee's Total Profit exceeds the Profit Cap, (iii) pay cash to the Issuer, (iv) reduce the number of Termination Fee Shares to be paid by the Grantee or (v) any combination thereof, so that Grantee's actually realized Total Profit shall not exceed the Profit Cap after taking into account the foregoing actions.

(b) As used herein, the term "Total Profit" shall mean the amount (before taxes) of the following: (a) the aggregate amount of (i) (x) the net cash amounts received by Grantee pursuant to the sale of Option Shares or Termination Fee Shares (or any other securities into which such Option Shares or Termination Fee Shares are converted or exchanged) to any unaffiliated party or to Issuer pursuant to this Agreement, less (y) the Grantee's purchase price of such Option Shares or other securities, (ii) any amounts received by Grantee on the transfer of the Option (or any portion thereof), if permitted hereunder, and (iii) the amount received by Grantee pursuant to

C-8

Section 7.2 of the Merger Agreement; minus (b) the amount of cash theretofore paid to the Issuer pursuant to this Section 12 plus the value of the Option Shares or Termination Fee Shares or other securities theretofore delivered to the Issuer for cancellation pursuant to this Section 12.

(c) Notwithstanding any other provision of this Agreement, nothing in this Agreement shall affect the ability of Grantee to receive nor relieve Issuer's obligation to pay a fee pursuant to Section 7.2 of the Merger Agreement; provided that if Total Profit received by Grantee would exceed the Profit Cap following the receipt of such fee, Grantee shall be obligated to comply with the terms of Section 12(a) within five (5)days of the later of (i) the date of receipt of such fee and (ii) the date of receipt of the net cash by Grantee pursuant to the sale of Option Shares or Termination Fee Shares (or, any other securities into which such Option Shares or Termination Fee Shares are converted or exchanged) pursuant to this Agreement.

(d) Notwithstanding any other provision of this Agreement, the Option may not be exercised for a number of Option Shares that would, as of the Notice Date, result in a Notional Total Profit (as defined below) of more than the Profit Cap; provided, however, that Grantee may indicate in its notice of exercise that Grantee is taking any of the actions described in subsection (a) hereof so as to reduce the Notional Total Profit to not more than the Profit Cap and preserve its rights to exercise the Option for the resulting number of Option Shares. "Notional Total Profit" shall mean, with respect to any number of Option Shares as to which the Grantee may propose to exercise the Option, the Total Profit determined as of the Notice Date assuming that the Option was exercised on such date for such number of Option Shares and assuming such Option Shares, together with all other Option Shares held by the Grantee and its affiliates as of such date, were sold for cash at the closing sales price for Common Stock as of the close of business on the preceding trading day.

(e) For purposes of Section 11(a) and clause (iii) of Section 11(b), the value of any Option Shares delivered by Grantee to the Issuer shall be the average closing sales price per share of Common Stock (or if there is no sale on such date then the average between the closing bid and ask prices on any such day) as reported by the Nasdaq National Market for the five (5) consecutive trading days preceding the day the Grantee's Total Profit exceeds the Profit Cap.

14. Application for Regulatory Approval. Each of Grantee and Issuer will use its commercially reasonable efforts to make all filings with, and to obtain consents of, all third parties and governmental authorities necessary to the consummation of the transactions contemplated by this Agreement, including without limitation making application to list the shares of Common Stock issuable hereunder on the Nasdaq National Market upon official notice of issuance.

15. Specific Performance. The parties hereto acknowledge that damages would be an inadequate remedy for a breach of this Agreement by either party hereto and that the obligations of the parties hereto shall be enforceable by either party hereto through injunctive or other equitable relief.

16. Separability of Provisions. If any term, provision, covenant or restriction contained in this Agreement is held by a court or a federal or state regulatory agency of competent jurisdiction to be invalid, void or unenforceable, the remainder of the terms, provisions and covenants and restrictions contained in this Agreement shall remain in full force and effect, and shall in no way be affected, impaired or invalidated.

17. Notices. All notices, claims, demands and other communications hereunder shall be deemed to have been duly given or made when delivered in person, by overnight courier or by facsimile at the respective addresses of the parties set forth in the Merger Agreement.

18. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws thereof.

21. Entire Agreement. Except as otherwise expressly provided herein or in the Merger Agreement, this Agreement contains the entire agreement between the parties with respect to the transactions contemplated hereunder and supersedes all prior arrangements or understandings with respect thereof, written or oral. The terms and conditions of this Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and permitted assigns.

This Agreement may not be modified, amended, altered or supplemented except upon the execution and delivery of a written agreement executed by the parties hereto.

22. Further Assurances. In the event of any exercise of the Option by Grantee, Issuer and Grantee shall execute and deliver all other documents and instruments and take all other action that may be reasonably necessary in order to consummate the transactions provided for by such exercise.

(b) "Existing Shares" means shares of Company Common Stock Beneficially Owned by Stockholder as of the date of this Voting Agreement provided that, in the event of a stock dividend or distribution, or any change in the Company Common Stock by reason of any stock dividend, split-up, recapitalization, combination, exchange of shares or the like, other than pursuant to the Merger, the term "Existing Shares" will be deemed to refer to and include the shares of Company Common Stock as well as all such stock dividends and distributions and any shares into which or for which any or all of the Securities (as defined hereinafter) may be changed or exchanged and appropriate adjustments shall be made to the terms and provisions of this Voting Agreement.

(c) "Securities" means the Existing Shares together with any shares of Company Common Stock or other securities of the Company acquired by Stockholder in any capacity after the date of this Voting Agreement and prior to its termination whether upon the exercise of options, warrants, or rights, the conversion or exchange of convertible or exchangeable securities, or by means of purchase, dividend, distribution, split-up, recapitalization, combination, exchange of shares, or the like, gift, bequest, inheritance, or as a successor in interest in any capacity, or otherwise.

Section 2. Representations and Warranties of Stockholder. Stockholder represents and warrants to Software.com as follows:

(c) "Securities" means the Existing Shares together with any shares of Company Common Stock or other securities of the Company acquired by Stockholder in any capacity after the date of this Voting Agreement and prior to its termination whether upon the exercise of options, warrants, or rights, the conversion or exchange of convertible or exchangeable securities, or by means of purchase, dividend, distribution, split-up, recapitalization, combination, exchange of shares, or the like, gift, bequest, inheritance, or as a successor in interest in any capacity, or otherwise.

ANNEX F

FORM OF PHONE.COM AFFILIATE LETTER

Software.com, Inc.
525 Anacapa Street
Santa Barbara, California 93101

Ladies and Gentlemen:

I have been advised that as of the date of this letter I may be deemed to be an "affiliate" of Phone.com, Inc., a Delaware corporation ("Phone"), as the term "affiliate" is used in and for purposes of Accounting Series, Releases 130 and 135, as amended, of the Securities and Exchange Commission (the "Commission"). Pursuant to the terms of the Agreement and Plan of Merger dated as of August 8, 2000 (the "Merger Agreement"), among Phone, Silver Merger Sub Inc., a Delaware corporation and a wholly owned subsidiary of Phone ("Merger Sub"), and Software.com, Inc., a Delaware corporation ("Software"), Merger Sub will be merged with and into Software (the "Merger").

I understand that in order for the Merger to be accounted for as a pooling of interests, affiliates of Phone and Software must not reduce their interests in or risk relative to their ownership of the shares of capital stock of either Phone or Software owned by them for a certain time period prior to and following the Merger.

As an inducement to Software to consummate the Merger, I represent to and covenant with Software that I will not, from the date thirty (30) days prior to the Effective Time (as defined in the Merger Agreement), sell, transfer or otherwise dispose of or reduce my risk (as contemplated by the SEC Accounting Series Release No. 135) with respect to any shares of the capital stock of either Software or Phone that I may hold and I will not sell, transfer or otherwise dispose of or reduce my risk (as contemplated by SEC Accounting Series Release No. 135) with respect to any shares of the capital stock of Phone until after such time as combined financial results (including combined sales and net income) covering at least 30 days of combined operations of Software and Phone have been published by Phone, in the form of a quarterly earnings report, an effective registration statement filed with the Commission, a report to the Commission on Form 10-K, 10-Q, or 8-K, or any other public filing or announcement which includes such combined results of operations (such period is referred to herein as the "Pooling Period"). Notwithstanding the foregoing, I understand that during the Pooling Period, subject to obtaining the prior written consent of Phone, I will not be prohibited from selling up to 10% of the shares of Phone Common Stock (the "10% Shares") owned by me, or making charitable contributions or bona fide gifts of the shares of Phone Common Stock owned by me, subject to the same restrictions; provided, however, that all holders of Phone Common Stock, as a group, and all holders of Software Common Stock, as a group, shall not be permitted to sell, in the aggregate, in excess of one percent (1%) of the total number of shares exchanged in the Merger (the "Threshold"). The 10% Shares shall be calculated in accordance with SEC Accounting Series Release 135, as amended, by Staff Accounting Bulletin No. 76. I covenant with Software that I will not sell, transfer or otherwise dispose of any 10% Shares during the period commencing from the Effective Time (as defined in the Merger Agreement) and ending on the last day of the Pooling Period except in compliance with Rule 145(d)(i) under the Act or pursuant to charitable contributions or bona fide gifts. I understand that Phone shall not withhold its consent to such disposition so long as such disposition is within the Threshold.

If at any time, Phone determines that the Merger may not be accounted for as a "pooling of interests," then the restrictions in the preceding paragraph shall terminate 45 days from the later of (i) the Effective Time and (ii) the date on which it is determined that the Merger may not be accounted for as a "pooling of interests."

I understand that, if at any time prior to the commencement of the Pooling Period I cease to be an "affiliate" of Phone, I may request in writing to Phone that I be released from my obligations hereunder and Phone shall grant such request if, in Phone's good faith judgment, Phone determines that I am, in fact, no longer an "affiliate" of Phone and such release would not otherwise prevent the Merger from being accounted for as a "pooling of interests."

F-1

Execution of this letter should not be considered an admission on my part that I am an "affiliate" of Phone as described in the first paragraph of this letter, or as a waiver of any rights I may have to object to any claim that I am such an affiliate on or after the date of this letter.

FORM OF SOFTWARE.COM AFFILIATE LETTER

Phone.com, Inc.
800 Chesapeake Drive
Redwood City, CA 94603

Ladies and Gentlemen:

I have been advised that as of the date of this letter I may be deemed to be an "affiliate" of Sofware.com, Inc., a Delaware corporation ("Software.com"), as the term "affiliate" is used in and for purposes of Accounting Series, Releases 130 and 135, as amended, of the Securities and Exchange Commission (the "Commission"). Pursuant to the terms of the Agreement and Plan of Merger dated as of August 8, 2000 (the "Merger Agreement"), among Phone.com, Inc., a Delaware corporation ("Phone"), Silver Merger Sub Inc., a Delaware corporation and a wholly owned subsidiary of Phone ("Merger Sub"), and Software.com, Merger Sub will be merged with and into Software.com (the "Merger").

As a result of the Merger, I may receive shares of common stock, par value $0.001 per share, of Phone (the "Phone Securities") in exchange for shares owned by me of common stock, par value $0.001 per share, of Software.com (or upon the exercise of options for such shares).

I hereby represent, warrant, and covenant to Phone that in the event I receive any Phone Securities as a result of the Merger:

A. I shall not make any sale, transfer, or other disposition of the Phone Securities in violation of the Securities Act of 1933, as amended (the "Act") or the rules and regulations (the "Rules and Regulations") of the Commission under the Act.

B. I have carefully read this letter and the Merger Agreement and discussed the requirements of such documents and other applicable limitations upon my ability to sell, transfer, or otherwise dispose of the Phone Securities, to the extent I felt necessary, with my counsel or counsel for Software.com.

C. I have been advised that the issuance of Phone Securities to me pursuant to the Merger will be registered with the Commission under the Act on a Registration Statement on Form S-4. However, I have also been advised that, since at the time the Merger is submitted for a vote of the stockholders of Software.com, (i) I may be deemed to be an affiliate of Software.com and (ii) the distribution by me of the Phone Securities has not been registered under the Act, I may not sell, transfer or otherwise dispose of the Phone Securities issued to me in the Merger unless (x) such sale, transfer or other disposition has been registered under the Act, (y) such sale, transfer or other disposition is made in conformity with Rule
145 (as such rule may be hereafter from time to time amended) promulgated by the Commission under the Act, or (z) in the opinion of counsel reasonably acceptable to Phone, or a "no action" letter obtained by me from the staff of the Commission, such sale, transfer or other disposition is otherwise exempt from registration under the Act.

D. I understand that Phone is under no obligation to register the sale, transfer, or other disposition of the Phone Securities by me or on my behalf under the Act or to take any other action necessary in order to make compliance with an exemption from such registration available.

E. I also understand that stop transfer instructions will be given to Phone's transfer agents with respect to the Phone Securities and that there will be placed on the certificates for the Phone Securities issued to me, or any substitutions therefor, a legend stating in substance:

"THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933 APPLIES,

G-1

AND MAY ONLY BE SOLD OR OTHERWISE TRANSFERRED IN COMPLIANCE WITH THE REQUIREMENTS OF RULE 145 OR PURSUANT TO A REGISTRATION STATEMENT UNDER THAT ACT OR AN EXEMPTION FROM SUCH REGISTRATION."

F. I also understand that unless the transfer by me of my Phone Securities has been registered under the Act or is a sale made in conformity with the provisions of Rule 145, Phone reserves the right to put the following legend on the certificates issued to my transferee:

"THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 AND WERE ACQUIRED FROM A PERSON WHO RECEIVED SUCH SHARES IN A TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933 APPLIES. THE SHARES HAVE BEEN ACQUIRED BY THE HOLDER NOT WITH A VIEW TO, OR FOR RESALE IN CONNECTION WITH, ANY DISTRIBUTION THEREOF WITHIN THE MEANING OF THE SECURITIES ACT OF 1933 AND MAY NOT BE SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN ACCORDANCE WITH AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OF 1933."

It is understood and agreed that the legends set forth in paragraphs E and F above shall be removed by delivery of substitute certificates without such legend if such legend is not required for purposes of the Act or this Agreement. It is understood and agreed that such legends and the stop orders referred to above will be removed if (i) evidence or representations satisfactory to Phone that the Phone Securities represented by such certificates are being or have been sold in a transaction made in conformity with the provisions of Rule 145(d) (as such rule may be hereafter from time to time amended) or (ii) Phone has received either an opinion of counsel, which opinion and counsel shall be reasonably satisfactory to Phone, or a "no action" letter obtained by me from the staff of the Commission, to the effect that the restrictions imposed by Rule 145 under the Act no longer apply to me.

I further represent to and covenant with Phone that I will not, from the date thirty (30) days prior to the Effective Time (as defined in the Merger Agreement), sell, transfer or otherwise dispose of or reduce my risk (as contemplated by the SEC Accounting Series Release No. 135) with respect to any Software.com shares or shares of the capital stock of Phone that I may hold and I will not sell, transfer or otherwise dispose of or reduce my risk (as contemplated by SEC Accounting Series Release No. 135) with respect to any Phone Securities received by me in the Merger or any other shares of the capital stock of Phone until after such time as combined financial results (including combined sales and net income) covering at least 30 days of combined operations of Software.com and Phone have been published by Phone, in the form of a quarterly earnings report, an effective registration statement filed with the Commission, a report to the Commission on Form 10-K, 10-Q or 8- K, or any other public filing or announcement which includes such combined results of operations (such period is referred to herein as the "Pooling Period"). Notwithstanding the foregoing, I understand that during the Pooling Period, subject to obtaining the prior written consent of Phone, I will not be prohibited from selling up to 10% of the shares of Phone Common Stock (the "10% Shares") received by me or shares of Phone Common Stock owned by me or making charitable contributions or bona fide gifts of the shares of Phone Common Stock received by me or shares of Phone Common Stock owned by me, subject to the same restrictions; provided, however, that all holders of Phone Common Stock, as a group, and all holders of Software.com Common Stock, as a group, shall not be permitted to sell, in the aggregate, in excess of one percent (1%) of the total number of shares exchanged in the Merger (the "Threshold"). The 10% Shares shall be calculated in accordance with SEC Accounting Series Release 135, as amended, by Staff Accounting Bulletin No.
76. I covenant with Phone that I will not sell, transfer or otherwise dispose of any 10% Shares during the period commencing from the Effective Time (as defined in the Merger Agreement) and ending on the last day of the Pooling Period except in compliance with Rule 145(d)(i) under the Act or pursuant to charitable contributions or bona fide gifts. I understand that Phone shall not withhold its consent to such disposition so long as such disposition is within the Threshold.

G-2

If at any time, Phone determines that the Merger may not be accounted for as a "pooling of interests," then the restrictions in the preceding paragraph shall terminate 45 days from the date on which it is determined that the Merger may not be accounted for as a "pooling of interests."

I understand that, if at any time prior to the commencement of the Pooling Period I cease to be an "affiliate" of Software.com, I may request in writing to Phone that I be released from my obligations hereunder and Phone shall grant such request if, in Phone's good faith judgment, Phone determines that I am, in fact, no longer an "affiliate" of Software.com and such release would not otherwise prevent the Merger from being accounted for as a "pooling of interests."

[LETTERHEAD OF CREDIT SUISSE FIRST BOSTON CORPORATION]

August 8, 2000

Board of Directors
Phone.com, Inc.
800 Chesapeake Drive
Redwood City, California 94063

Members of the Board:

You have asked us to advise you with respect to the fairness, from a financial point of view, to Phone.com, Inc. ("Phone.com") of the Exchange Ratio (as defined below) set forth in the Agreement and Plan of Merger, dated as of August 8, 2000 (the "Merger Agreement"), by and among Phone.com, Silver Merger Sub Inc., a wholly owned subsidiary of Phone.com ("Merger Sub"), and Software.com, Inc. ("Software.com"). The Merger Agreement provides for, among other things, the merger (the "Merger") of Merger Sub with and into Software.com pursuant to which each outstanding share of the common stock, par value $0.001 per share, of Software.com ("Software.com Common Stock") will be converted into the right to receive 1.6105 (the "Exchange Ratio") shares of the common stock, par value $0.001 per share, of Phone.com ("Phone.com Common Stock").

In arriving at our opinion, we have reviewed the Merger Agreement and certain publicly available business and financial information relating to Phone.com and Software.com. We also have reviewed certain other information relating to Phone.com and Software.com, including certain publicly available financial forecasts, provided to or discussed with us by Phone.com and Software.com, and have met with the managements of Phone.com and Software.com to discuss the businesses and prospects of Phone.com and Software.com and potential synergies that might be achieved in the Merger. We also have considered certain financial and stock market data of Phone.com and Software.com, and we have compared those data with similar data for publicly held companies in businesses similar to those of Phone.com and Software.com, and we have considered, to the extent publicly available, the financial terms of certain other business combinations and other transactions which have recently been effected. We also considered such other information, financial studies, analyses and investigations and financial, economic and market criteria which we deemed relevant.

In connection with our review, we have not assumed any responsibility for independent verification of any of the foregoing information and have relied on such information being complete and accurate in all material respects. With respect to the financial forecasts for Phone.com and Software.com referred to above, we assumed, with the consent of the managements of Phone.com and Software.com, that such forecasts represent reasonable estimates and judgments as to the future financial performance of Phone.com and Software.com. In addition, we have relied, without independent verification, upon the assessments of the managements of Phone.com and Software.com as to (i) the strategic benefits anticipated to result from the Merger, (ii) the existing and future technology and products of Phone.com and Software.com and the risks associated with such technology and products, (iii) their ability to integrate the businesses of Phone.com and Software.com and (iv) their ability to retain key employees of Phone.com and Software.com. We also have assumed, with your consent, that the Merger will be treated as a tax-free reorganization for federal income tax purposes. In addition, we have not been requested to make, and have not made, an independent evaluation or appraisal of the assets or liabilities (contingent or otherwise) of Phone.com or Software.com, nor have we been furnished with any such evaluations or appraisals. Our opinion is necessarily based upon information available to us, and financial, economic, market and other conditions as they exist and can be evaluated, on the date hereof. We are not expressing any opinion as to what the value of the Phone.com Common Stock actually will be when issued pursuant to the Merger or the prices at which the Phone.com Common Stock will trade subsequent to the Merger.

We have acted as financial advisor to Phone.com in connection with the Merger and will receive a fee for our services, a significant portion of which is contingent upon the consummation of the Merger. We also will receive a fee upon delivery of this opinion. We and our affiliates have in the past provided financial services to Phone.com and Software.com, and may in the future provide financial services to Phone.com, unrelated to the proposed Merger, for which services we have received and will receive compensation. In the ordinary course of business, we and our affiliates may actively trade the debt and equity securities of Phone.com and Software.com for our and such affiliates' accounts and for the accounts of customers and, accordingly, may at any time hold a long or short position in such securities.

It is understood that this letter is for the information of the Board of Directors of Phone.com in connection with its evaluation of the Merger and does not constitute a recommendation to any stockholder as to how such stockholder should vote with respect to any matter relating to the Merger.

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Exchange Ratio is fair to Phone.com from a financial point of view.

Very truly yours,

[LETTERHEAD OF MORGAN STANLEY & CO. INCORPORATED]

August 8, 2000
Board of Directors
Software.com, Inc.
525 Anacapa Street,
Santa Barbara, CA 93101

Members of the Board:

We understand that Software.com, Inc. ("Software.com" or the "Company"), Phone.com, Inc. ("Phone.com"), and Phone.com Subsidiary, Inc. ("Merger Sub"), a wholly-owned subsidiary of Phone.com, propose to enter into an Agreement and Plan of Merger, substantially in the form of the draft dated August 8, 2000 (the "Merger Agreement") which provides, among other things, for the merger (the "Merger") of Merger Sub with and into Software.com. Pursuant to the Merger, Software.com will become a wholly-owned subsidiary of Phone.com and each outstanding share of common stock, $0.001 par value per share (the "Software.com Common Stock") of Software.com, other than shares held in treasury or held by Phone.com or any affiliates of Software.com or Phone.com will be converted into the right to receive 1.6105 shares (the "Exchange Ratio") of common stock, $0.001 par value per share (the "Phone.com Common Stock") of Phone.com. The terms and conditions of the Merger are more fully set forth in the Merger Agreement.

You have asked for our opinion as to whether the Exchange Ratio pursuant to the Merger Agreement is fair from a financial point of view to the holders of shares of Software.com Common Stock.

For purposes of the opinion set forth herein, we have:

(i) reviewed certain publicly available financial statements and other information of Software.com and Phone.com, respectively;

(ii) reviewed certain internal financial statements and other financial and operating data concerning Software.com and Phone.com, prepared by the managements of Software.com and Phone.com, respectively;

(iii) reviewed certain financial projections prepared by the managements of Software.com and Phone.com;

(iv) reviewed the pro forma impact of the Merger on certain operational and financial metrics for the combined company;

(v) discussed the past and current operations and financial condition and the prospects of Software.com and Phone.com, including a review of publicly available projections from equity research analyst estimates and information relating to certain strategic, financial and operational benefits anticipated from the Merger, with senior executives of Software.com and Phone.com, respectively;

(vi) reviewed the reported prices and trading activity for the Software.com Common Stock and Phone.com Common Stock;

(vii) compared the financial performance of Software.com and Phone.com and the prices and trading activity of the Software.com Common Stock and Phone.com Common Stock with that of certain other publicly-traded companies comparable to Software.com and Phone.com, respectively, and their securities;

(viii) reviewed the financial terms, to the extent publicly available, of certain comparable merger transactions;

(ix) reviewed and discussed with the senior managements of Software.com and Phone.com their strategic rationales for the Merger;

(x) participated in discussions and negotiations among representatives of Software.com, Phone.com and their financial and legal advisors;

(xi) reviewed the draft Merger Agreement and certain related documents; and

(xii) performed such other analyses and considered such other factors as Morgan Stanley deemed appropriate.

K-1

We have assumed and relied upon, without independent verification, the accuracy and completeness of the information reviewed by us for the purposes of this opinion. With respect to the financial projections and information relating to the strategic, financial and operational benefits anticipated from the Merger, we have assumed that they were reasonably prepared on bases reflecting the best currently available estimates and judgements of the future financial performance of Software.com and Phone.com, respectively. In addition, we have assumed that the Merger will be consummated in accordance with the terms set forth in the Merger Agreement and will be treated as a tax- free reorganization pursuant to Section 368(a) of the Internal Revenue Code of 1986. Our opinion is necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof.

We have relied upon the assessment by the managements of Software.com and Phone.com of their ability to retain key employees of Software.com and Phone.com, respectively. We have also relied upon, without independent verification, the assessment by the managements of Software.com and Phone.com of: (i) the strategic, financial and other benefits expected to result from the Merger; (ii) the timing and risks associated with the integration of Software.com and Phone.com; and (iii) the validity of, and risks associated with, Software.com's and Phone.com's existing and future technologies, services or business models. We have not made any independent valuation or appraisal of the assets or liabilities or technology of Software.com and Phone.com, nor have we been furnished with any such appraisals.

In arriving at our opinion, we were not authorized to solicit, and did not solicit, interest from any party with respect to an acquisition, business combination or other extraordinary transaction involving Software.com.

We have acted as financial advisor to the Board of Directors of Software.com in connection with this transaction and will receive a fee for our services. In the ordinary course of our business we may actively trade the securities of Software.com and Phone.com for our own account and for the accounts of our customers and, accordingly, may at any time hold a long or short position in such securities.

It is understood that this letter is for the information of the Board of Directors of Software.com and may not be used for any other purpose without our prior written consent, except that this opinion may be included in its entirety, if required, in any filing of a proxy or registration statement with the Securities and Exchange Commission made by Software.com in respect of this transaction. In addition, this opinion does not in any manner address the prices at which the Software.com Common Stock or the Phone.com Common Stock will trade following the consummation of the Merger, and Morgan Stanley & Co. Incorporated expresses no opinion or recommendation as to how the stockholders of Software.com should vote at the stockholders' meeting to be held in connection with the Merger.

Based upon and subject to the foregoing, we are of the opinion on the date hereof that the Exchange Ratio pursuant to the Merger Agreement is fair from a financial point of view to the holders of shares of Software.com Common Stock.

Very truly yours,

Morgan Stanley & Co. Incorporated

PART II: INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers

Section 102 of the Delaware General Corporation Law, or the DGCL, as amended, allows a corporation to eliminate the personal liability of directors of a corporation to the corporation or its stockholders for monetary damages for a breach of fiduciary duty as a director, except where the director knowingly violated a law, authorized the payment of a dividend or approved a stock repurchase in violation of Delaware corporate law or obtained an improper personal benefit.

Section 145 of the DGCL provides, among other things, the Phone.com may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding (other than an action by or in the right of Phone.com) by reason of the fact that the person is or was a director, officer, agent or employee of Phone.com or is or was serving at Phone.com's request as a director, officer, agent, or employee of another corporation, partnership, joint venture, trust or other enterprise, against expenses, including attorneys' fees, judgment, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with the action, suit or proceeding. The power to indemnify applies (a) if the person is successful on the merits or otherwise in defense of any action, suit or proceeding, or (b) if the person acted in good faith and in a manner he or she reasonably believes to be in the best interest, or not opposed to the best interest, of Phone.com, and with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. The power to indemnify applies to actions brought by or in the right of Phone.com as well, but only to the extent of defense expenses (including attorneys' fees but excluding amounts paid in settlement) actually and reasonably incurred and not to any satisfaction of judgment or settlement of the claim itself, and with the further limitation that in these actions no indemnification shall be made in the event of any adjudication of negligence or misconduct in the performance of his or her duties to Phone.com, unless the court believes that in light of all the circumstances indemnification should apply.

Section 174 of the DGCL provides, among other things, that a director, who willfully or negligently approves of an unlawful payment of dividends or an unlawful stock purchase or redemption, may be held liable for these actions. A director who was either absent when the unlawful actions were approved or dissented at the time, may avoid liability by causing his or her dissent to these actions to be entered in the books containing the minutes of the meetings of the board of directors at the time the action occurred or immediately after the absent director receives notice of the unlawful acts.

Phone.com's Amended and Restated Certificate of Incorporation includes a provision that eliminates the personal liability of its directors for monetary damages for breach of fiduciary duty as a director.

Phone.com's Amended and Restated Bylaws provide that:

. it must indemnify its directors and officers to the fullest extent permitted by Delaware law;

. it may indemnify its other employees and agents to the same extent that it indemnifies its officers and directors; and

. it must advance expenses, as incurred, to its directors and executive officers, and its other employees or agents following authorization of indemnification of such employees or agents, in connection with a legal proceeding to the fullest extent permitted by Delaware law.

The indemnification provisions contained in Phone.com's Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws are not exclusive of any other rights to which a person may be entitled by law, agreement, vote of stockholders or disinterested directors or otherwise. In addition, Phone.com may maintain insurance on behalf of its directors and executive officers insuring them against any liability asserted against them in their capacities as directors or officers or arising out of this status.

Item 22. Undertakings

The undersigned registrant hereby undertakes:

(a)(1) that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.

(2) that every prospectus: (i) that is filed pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet the requirements of
Section 10(a)(3) of the Securities Act of 1933, as amended, and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, as amended, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(b) Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933, as amended, and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

(c) to respond to requests for information that is incorporated by reference into the prospectus pursuant to Item 4, 10(b), 11, or 13 of this Form S-4 within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information

II-4


contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

(d) to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.

II-5
