PROSPECTUS SUMMARY

ABOUT OUR COMPANY

We develop, market, and sell microprocessors, our technology behind the microprocessors, and communication products which enable computers to talk to one another. These products can be used to connect to the Internet or other telecommunication networks. We also own special radar technology which, when fully developed, may allow us to penetrate the ground or structures to find various objects. We also owned gas plasma antenna technology which we sold for $250,000 in August 1999. We potentially could receive up to an additional $250,000 from the sale of the gas plasma technology in the form of royalties. Our strategy is to exploit our technologies through product sales, licensing, and strategic alliances.

ABOUT OUR PRODUCTS AND MARKET

The market for our products is growing swiftly because of the Internet. The Internet provides its users with new ways to communicate and to do business. The growth of the Internet is creating a demand for equipment such as ours, including our microprocessor, traditional analog modems and higher speed digital modems. The Internet has also introduced a new programming language known as Java. With Java, data and programs do not have to be stored on the user's computer; they can reside anywhere on the Internet to be called upon as needed. Java can run on a variety of computer operating systems, thus avoiding the problem of incompatibility across networks, and Java offers a high degree of data security. Because of Java's useful features, we believe that it may also become a popular programming language for another type of computer application known as embedded systems or controls. Our microprocessor enables people to program more efficiently in Java.

A microprocessor is the computer chip that provides intelligence for electronic devices. Our microprocessor technology, trade named ShBoom, uses our simplified proprietary design to produce a single high-performance computer chip, which can be used instead of several different chips to perform the same function. Our first microprocessors, the PSC1000 family, are targeted as Java programming language processors and for use in embedded controllers. Embedded controllers are used in sophisticated products, such as laser printers, motion and industrial controllers, cable and satellite modems and television set-top boxes. We are also licensing the ShBoom technology to others which allows them to customize applications of the technology depending upon their requirements.

One of our communication products, the CyberShark digital modem, provides consumers with a high-performance interface between a computer and telephone lines. We also offer original equipment manufacturers, systems integrators and value added resellers products for high speed access to the Internet, remote access drivers, video conferencing equipment and digital telephony products.

Our ground penetrating radar prototype has demonstrated the ability to see through solid objects (walls and barriers) and in certain types of ground has been able to see objects as small as six inches in size at a depth of ten feet.

ABOUT OUR INVESTMENT AGREEMENT

We have entered into an investment agreement with Swartz Private Equity, LLC to raise up to $30 million through a series of sales of our common stock. The dollar amount of each sale is limited by our common stock's trading volume, and a minimum period of time must elapse between each sale. Each sale will be to Swartz. In turn, Swartz will either sell our stock in the open market, place our stock through negotiated transactions with other investors, or hold our stock in their own portfolio. This prospectus covers the resale of our stock by Swartz either in the open market or to other investors.

ADDITIONAL SHARES WE ARE REGISTERING

Recently, we issued short-term notes (with warrants attached) payable to private investors. The resale of the common stock by these private investors, obtainable on the exercise of the warrants, is included in this registration.

RISK FACTORS

The common shares being offered for resale by the selling shareholders are highly speculative in nature, involve a high degree of risk and should be purchased only by persons who can afford to lose their entire investment in the common shares. Before purchasing any of the common shares, you should carefully consider the following factors relating to our business and prospects.

PATRIOT'S MAJOR PRODUCT LINE, THE MICROPROCESSOR, HAS HAD LIMITED REVENUES AND IS STILL IN THE PRE-PRODUCTION STAGE OF DEVELOPMENT

We are in the pre-production stage of development on our major product line, the microprocessor, which has had limited revenues. Our other product lines have not generated enough revenue to support our company. Therefore, we have limited financial results upon which you may judge our potential. We may not become profitable. We have experienced in the past and may experience in the future many of the problems, delays and expenses encountered by any early stage business, many of which are beyond our control. These include:

- substantial delays and expenses related to testing and development of our new products,

- production and marketing problems encountered in connection with our new and existing products and technologies,

- competition from larger and more established companies, and

- lack of market acceptance of our new products and technologies.

PATRIOT HAS A HISTORY OF LOSSES, EXPECTS FUTURE LOSSES AND MAY NOT ACHIEVE OR SUSTAIN ANNUAL PROFITABILITY

We expect to incur operating losses in the future. Sales of our products may never generate sufficient revenues to fund our continuing operations. We may never generate positive cash flow or attain profitability. To date, we have incurred significant losses. As of February 29, 2000, our accumulated deficit was $30,553,919. For the fiscal year ended May 31, 1999, we incurred a net loss of $4,276,456 and for the previous fiscal year a net loss of $7,514,785. These losses have resulted primarily from:

- significant costs associated with the development of our products,

- costs associated with the marketing of those products,

- the interest charges and expenses related to previous equity and debt financings, and

- compensation costs related the cashless exercise of options and to the earnout of escrowed common shares.

PATRIOT'S CERTIFIED PUBLIC ACCOUNTANTS HAVE ADDED AN EXPLANATORY PARAGRAPH TO THEIR OPINION ON PATRIOT'S FINANCIAL STATEMENT

In connection with their report on our Consolidated Financial Statements as of and for the year ended May 31, 1999, our independent certified public accountants expressed substantial doubt about our ability to continue operating as a going concern because of recurring net losses and negative cash flow from operations.

6

PATRIOT MAY NOT BE ABLE TO OBTAIN ADDITIONAL CAPITAL TO FUND ITS OPERATIONS WHEN NEEDED

A lack of additional funding could force us to substantially curtail or cease our operations, which would have a material adverse effect on our business. Our ability to raise funds under the investment agreement is subject to certain conditions. These conditions include the effectiveness of a registration statement covering the resale of the shares sold under the investment agreement and a limitation on our ability to issue shares based on the volume of trading in the common stock. We anticipate that our future cash requirements may be supplemented by improved product sales, the sale of additional equity securities, debt financing and/or the sale or licensing of certain of our technologies. However, there can be no assurance that any future funds required will be generated from operations or from other potential sources. Further, any such required funds may only be available on unattractive terms and may significantly dilute the value of our existing shares.

PATRIOT MAY EXPERIENCE DIFFICULTIES IN THE INTRODUCTION OF NEW PRODUCTS THAT COULD RESULT IN PATRIOT HAVING TO INCUR SIGNIFICANT UNEXPECTED EXPENSES OR DELAY THE LAUNCH OF NEW PRODUCTS

Our technologies and products are in various stages of development. These development stage products may not be completed in time to allow production or marketing due to the inherent risks of new product and technology development, limitations on financing, competition, obsolescence, loss of key personnel and other factors. Although we may license some of our technology at its current stage of development, there can be no assurance that we will be able to do so. Unanticipated technical obstacles can arise at any time and result in lengthy and costly delays or in a determination that further development is not feasible. Discovery of microprocessor design errors, frequent in the industry prior to and after production, could result in lengthy and costly redesign, fabrication (production) and testing in an industry where new technology rapidly eclipses prior innovations.

The development of our technologies has taken longer than anticipated and could be additionally delayed. Therefore, there can be no assurance of timely completion and introduction of improved products on a cost-effective basis, or that such products, if introduced, will achieve market acceptance such that, in combination with existing products, they will sustain us or allow us to achieve profitable operations.

INTENSE COMPETITION IN THE MARKET FOR MICROPROCESSORS COULD PREVENT PATRIOT FROM INCREASING OR SUSTAINING REVENUE AND PREVENT PATRIOT FROM ACHIEVING OR SUSTAINING ANNUAL PROFITABILITY

Our products could be rendered noncompetitive or obsolete. Technological competition from larger and more established microprocessor, digital communication and radar companies is significant and expected to increase. Most of the companies with which we compete and expect to compete have far greater capital resources and more significant research and development staffs, marketing and distribution programs and facilities, and many of them have substantially greater experience in the production and marketing of products. Our ability to compete effectively may be adversely affected by the ability of these competitors to devote greater resources to the sale and marketing of their products than we can. In addition, one or more of our competitors may succeed or may already have succeeded in developing technologies and products that are more effective than

7

any of those we currently offer or are developing.

PATRIOT'S LIMITED ABILITY TO PROTECT ITS INTELLECTUAL PROPERTY MAY ADVERSELY AFFECT ITS ABILITY TO COMPETE

A successful challenge to our ownership of our technology could materially damage our business prospects. Our technologies may infringe upon the proprietary rights of others. Licenses required by us from others may not be available on commercially reasonable terms, if at all. We rely on a combination of patents, trademarks, copyrights, trade secret laws, confidentiality procedures and licensing arrangements to protect our intellectual property rights. We currently have eight U.S. patents issued and five U.S. patents pending. We have one patent pending in Europe and Japan and have filed an application for another patent in Europe, Japan and elsewhere. Any issued patent may be challenged and invalidated. Patents may not issue from any of our pending applications. Any claims allowed from existing or pending patents may not be of sufficient scope or strength to provide significant protection for our products. Patents may not be issued in all countries where our products can be sold so as to provide meaningful protection or any commercial advantage to us. Our competitors may also be able to design around our patents.

Vigorous protection and pursuit of intellectual property rights or positions characterize the fiercely competitive semiconductor industry, which has resulted in significant and often protracted and expensive litigation. Therefore, our competitors may assert that our technologies or products infringe on their patents or proprietary rights. Problems with patents or other rights could increase the cost of our products or delay or preclude new product development and commercialization by us. If infringement claims against us are deemed valid, we may not be able to obtain appropriate licenses on acceptable terms or at all. Litigation could be costly and time-consuming but may be necessary to protect our future patent and/or technology license positions or to defend against infringement claims.

We did not develop the basic ShBoom technology. We acquired the rights in this technology through a series of agreements from two co- inventors. We have been, and may again be, subject to claims from such prior parties related to the technology. Such parties may also attempt to exploit the technology independently of our rights to do so. One of the co-inventors of this technology has filed a lawsuit against another prior owner and us. Although many of the issues raised in this lawsuit have been dismissed in favor of the prior owner and us, one issue related to the release of our common shares to the co-inventor is still open and may go to trial if not resolved. The asset purchase agreement and plan of reorganization between Patriot, nanoTronics Corporation and Helmut Falk was the agreement under which we acquired the basic ShBoom technology. The agreement also contained a number of warranties and indemnities related to the ownership of the technology and other matters. We believe nanoTronics Corporation has been liquidated and, due to Mr. Falk's death in July 1995, our ability to obtain satisfaction for any future claims as a result of a breach of the agreement may be limited.

PATRIOT CAN NOT PREDICT THE OUTCOME OF A LAWSUIT IN WHICH IT IS A DEFENDANT

In October 1998, we were sued in the District Court for Travis County, Texas by a co-inventor of the original ShBoom technology. We removed the suit to the United States District Court for the Western District of Texas, Austin Division, where it was dismissed because the court

8

did not have jurisdiction over us. The suit has been refiled in the Superior Court of San Diego County, California. The suit also names as defendants nanoTronics and Gloria Felcyn on behalf of the Falk Family Trust. We purchased the technology from nanoTronics in 1994. The suit sought a judgment for damages based on royalties allegedly due the co-inventor, a rescission of the technology transfer agreement between nanoTronics and the co-inventor, and a restoration of the technology to the co-inventor. In February 2000 the judge ruled in our favor on all of the above issues, however, there remains one additional issue related to the release of our common shares to the co-inventor. If we can not settle out of court with the co-inventor, this remaining issue may go to trial. We and the other defendants intend to vigorously contest the plaintiff's last allegation.

PATRIOT IS DEPENDENT ON THE INTERNET, ISDN AND JAVA FOR ACCEPTANCE OF ITS PRODUCTS

The marketing of our digital communication products and microprocessor products will depend in large part upon a robust and growing industry and infrastructure for providing Internet access and carrying Internet traffic and the emergence of Java as a widespread programming language for the Internet or in embedded applications. The infrastructure or complementary products necessary to make the Internet a viable commercial marketplace may not be developed, or, even if they are developed, the Internet may not become a viable commercial marketplace. Even if the Internet continues its robust growth, there may not be a market for our ISDN products, given their dependence upon telephone company policies and rates and the intense competition from other access technologies such as cable modems and satellites. Also, Java may not become a widespread programming language for the Internet or in embedded applications, and a market may not develop for devices to run Java efficiently. If the Internet does not become a viable commercial marketplace, or if ISDN products become technologically obsolete, or if Java applications for microprocessors do not develop, then our business, operating results and financial condition will be materially and adversely affected.

PATRIOT MAY BE IN VIOLATION OF SECTION 5 OF THE SECURITIES ACT AND CONSEQUENTLY CERTAIN INVESTORS MAY HAVE RESCISSION RIGHTS AS TO SHARES ACQUIRED AND PATRIOT AND CERTAIN PRINCIPALS OF PATRIOT MAY BE SUBJECT TO CIVIL AND CRIMINAL PENALTIES

In June 1999, we issued shares to an institutional investor upon the conversion of a short term note plus accrued interest in the amount of $116,183 and during the nine months ended February 29, 2000, we issued shares under a previous investment agreement with Swartz for $5,000,000. These sales occurred after the filing of a registration statement by us and, therefore, by making these sales we may have violated Section 5 of the Securities Act of 1933. In July 1999, we amended and restated a previous investment agreement with Swartz to eliminate the discretion of Swartz as to the timing of its purchase of our common stock. By entering into the amended and restated investment agreement, we completed our sale of common stock to Swartz. Since this private sale to Swartz occurred after we filed our registration statement, we may have sold securities to Swartz in violation of Section 5 of the Securities Act of 1933. Consequently, the institutional investor and Swartz, at their options, may have the right, for up to one year after the purchase of the common stock, to rescind their purchases. In addition, Patriot and certain officers and directors of Patriot may be subject to civil and criminal penalties for potential violation of either or both Section 5 of the Securities Act of 1933 and applicable state law as a result of these sales.

PLAN OF DISTRIBUTION

Each selling shareholder is free to offer and sell his or her common shares at such times, in such manner and at such prices as he or she may determine. The types of transactions in which the common shares are sold may include transactions in the over-the-counter market (including block transactions), negotiated transactions, the settlement of short sales of common shares, or a combination of such methods of sale. The sales will be at market prices prevailing at the time of sale or at negotiated prices. Such transactions may or may not involve brokers or dealers. The selling shareholders have advised us that they have not entered into any agreements, understandings or arrangements with any underwriters or broker-dealers regarding the sale of their securities. The selling shareholders do not have an underwriter or coordinating broker acting in connection with the proposed sale of the common shares.

The selling shareholders may effect such transactions by selling common stock directly to purchasers or to or through broker-dealers, which may act as agents or principals. Such broker-dealers may receive compensation in the form of discounts, concessions, or commissions from the selling shareholders. They may also receive compensation from the purchasers of common shares for whom such broker-dealers may act as agents or to whom they sell as principal, or both (which compensation as to a particular broker-dealer might be in excess of customary commissions).

Swartz Private Equity, LLC is, and each remaining selling shareholder and any broker-

10

dealer that acts in connection with the sale of common shares may be deemed to be, an "underwriter" within the meaning of Section 2(11) of the Securities Act. Any commissions received by such broker-dealers and any profit on the resale of the common shares sold by them while acting as principals might be deemed to be underwriting discounts or commissions.

Because Swartz is, and each remaining selling shareholder may be deemed to be, an "underwriter" within the meaning of Section 2(11) of the Securities Act, the selling shareholders will be subject to prospectus delivery requirements.

We have informed the selling shareholders that the anti-manipulation rules of the SEC, including Regulation M promulgated under the Securities and Exchange Act, may apply to their sales in the market and has provided the selling shareholders with a copy of such rules and regulations.

Selling shareholders also may resell all or a portion of the common shares in open market transactions in reliance upon Rule 144 under the Securities and Exchange Act, provided they meet the criteria and conform to the requirements of such Rule.

SELLING SHAREHOLDERS

INVESTMENT AGREEMENT

OVERVIEW. On May 2, 2000, we entered into an investment agreement with Swartz Private Equity, LLC. The investment agreement entitles us to issue and sell our common stock for up to an aggregate of $30 million from time to time during a three-year period following the effective date of this registration statement. This is also referred to as a put right.

PUT RIGHTS. In order to invoke a put right, we must have an effective registration statement on file with the SEC registering the resale of the common shares which may be issued as a consequence of the invocation of that put right. Additionally, we must give at least ten but not more than twenty business days advance notice to Swartz of the date on which we intend to exercise a particular put right and we must indicate the number of shares of common stock we intend to sell to Swartz. At our option, we may also designate a maximum dollar amount of common stock (not to exceed $3 million) which we will sell to Swartz during the put and/or a minimum purchase price per common share at which Swartz may purchase shares during the put. The number of common shares sold to Swartz may not exceed 20% of the aggregate daily reported trading volume during a period which begins on the business day immediately following the day we invoked the put right and ends on and includes the day which is twenty business days after the date we invoked the put right.

Swartz will pay us a percentage of the market price for each share of common stock under the put. If the market price is less than $2.00 per share, the percentage will be 90%; and if the market price is $2.00 or greater, the percentage will be 93%. Market price is defined as the lowest closing bid price for the common stock during the applicable pricing period which consists of two consecutive ten business day periods following the date notice of the put was provided to Swartz. However, the market price may not be less than the designated minimum per share price, if any, that we indicated in our notice.

WARRANTS. Within five business days after the end of each pricing period, we are

11

required to issue and deliver to Swartz a warrant to purchase a number of shares of common stock equal to 15% of the common shares issued to Swartz in the applicable put. Each warrant will be exercisable at a price which will initially equal 110% of the closing bid price on the put date for the applicable put. The warrants will have semi-annual reset provisions. Each warrant will be immediately exercisable and have a term beginning on the date of issuance and ending five years thereafter.

LIMITATIONS AND CONDITIONS PRECEDENT TO OUR PUT RIGHTS. Swartz is not required to acquire and pay for any common shares with respect to any particular put for which:

- we have announced or implemented a stock split or combination of our common stock;

- we have paid a common stock dividend;

- we have made a distribution of our common stock or of all or any portion of our assets between the put notice date and the date the particular put closes; or

- we have consummated a major transaction (including a transaction, which constitutes a change of control) between the advance put notice date and the date the particular put closes.

SHORT SALES. Swartz and its affiliates are prohibited from engaging in short sales of our common stock unless they have received a put notice and the amount of shares involved in a short sale does not exceed the number of shares specified in the put notice.

CANCELLATION OF PUTS. We must cancel a particular put between the date of the advance put notice and the last day of the pricing period if:

- we discover an undisclosed material fact relevant to Swartz's investment decision;

- the registration statement registering resales of the common shares becomes ineffective; or

- shares are delisted from the then primary exchange.

However, we will be required to issue common shares equal to the lesser of:

- 20% of the daily reported trading volume of our common stock during the pricing periods up to the applicable put cancellation date;

- the number of shares of common stock put to Swartz which when multiplied by the applicable put share price equals the designated maximum dollar amount for the put; or

- 9.9% of the total amount of our common stock that would be outstanding upon completion of the put.

SHAREHOLDER APPROVAL. We may currently issue more than 20% of our outstanding shares. If we become listed on the Nasdaq Small Cap Market or Nasdaq National Market, then we must get shareholder approval to issue more than 20% of our outstanding shares. Since we are currently a bulletin board company, we do not need shareholder approval.

12

TERMINATION OF INVESTMENT AGREEMENT. We may also terminate our right to initiate further puts or terminate the investment agreement by providing Swartz with notice of such intention to terminate; however, any such termination will not affect any other rights or obligations we have concerning the investment agreement or any related agreement.

RESTRICTIVE COVENANTS. During the term of the investment agreement and for a period of one-year thereafter, we are prohibited from certain transactions. These include the issuance of any debt or equity securities in a private transaction which are convertible or exercisable into shares of common stock at a price based on the trading price of the common stock at any time after the initial issuance of such securities or with a fixed conversion or exercise price subject to adjustment. We are also prohibited from entering into any private equity line type agreements similar to the investment agreement without obtaining Swartz's prior written approval.

RIGHT OF FIRST REFUSAL. Swartz has a right of first refusal to purchase any variable priced securities offered by us in any private transaction which closes on or prior to six months after the termination of the investment agreement.

SWARTZ'S RIGHT OF INDEMNIFICATION. We are obligated to indemnify Swartz (including their stockholders, officers, directors, employees and agents) from all liability and losses resulting from any misrepresentations or breaches we made in connection with the investment agreement, our registration rights agreement, other related agreements, or the registration statement.

  microprocessor and obtaining tools to make use of
  the processor more user- friendly.

DESCRIPTION OF SECURITIES

Our authorized capital stock consists of 100,000,000 shares of common stock, $.00001 par value per share. At May 2, 2000, a total of 50,991,374 common shares were issued and outstanding. The holders of common stock are entitled to one vote for each share held. The affirmative vote of a majority of votes cast at a meeting which commences with a lawful quorum is sufficient for approval of most matters upon which shareholders may or must vote, including the questions presented for approval or ratification at the Annual Meeting. However, removal of a director from office or repeal of the certificate of incorporation in its entirety require the affirmative vote of a majority of the total voting power for approval, and certain other matters (such as shareholder amendment of the bylaws, and amendment, repeal or adoption of any provision inconsistent with provisions in the certificate of incorporation regarding indemnification of directors, officers and others, exclusion of director liability, and our election not to be governed by statutory provisions concerning business combinations with interested shareholders) require the affirmative vote of two-thirds of the total voting power for approval. Common shares do not carry cumulative voting rights, and holders of more than 50% of the common stock have the power to elect all directors and, as a practical matter, to control the company. Holders of common stock are not entitled to preemptive rights, and the common stock may only be redeemed at our election.

A special meeting of shareholders may be called by or at the request of:

- the Chairman of the Board,

- the President or any two directors, and

- persons owning in the aggregate not less than 20% of the issued and outstanding common shares entitled to vote in elections for directors.

After the satisfaction of requirements with respect to preferential dividends, if any, holders of common stock are entitled to receive, pro rata, dividends when and as declared by the board of directors out of funds legally available therefor. Upon our liquidation, dissolution or winding-up, after distribution in full of the preferential amount, if any, to be distributed to holders of the preferred stock, holders of common stock are entitled to share ratably in our assets legally available for distribution to our shareholders.

Our board of directors is authorized to issue 5,000,000 shares of undesignated preferred stock, $.00001 par value, without any further action by the stockholders. The board of directors may also divide any and all shares of preferred stock into series and fix and determine the relative rights and preferences of the preferred stock, such as the designation of series and the number of shares constituting such series, dividend rights, redemption and sinking fund provisions, liquidation and dissolution preferences, conversion or exchange rights and voting rights, if any. Issuance of preferred stock by the board of directors will result in such shares having dividend and/or liquidation preferences senior to the rights of the holders of common stock and could dilute the voting rights of the holders of common stock. There are currently no shares of preferred stock issued and outstanding.

We have not paid any cash dividends to date, and no cash dividends will be declared or paid on the common shares in the foreseeable future. Payment of dividends is solely at the discretion of our board of directors.

ITEM 15. INDEMNIFICATION OF OFFICERS AND DIRECTORS.

Pursuant to the Company's Certificate of Incorporation, and as permitted by
Section 145 of the General Corporation Law of Delaware, the Company may indemnify its directors and officers under certain circumstances against reasonable expenses (including court costs and attorney's fees), judgments, penalties, fines, and amounts paid in settlement actually and reasonably incurred in connection with any action, suit or proceeding, whether civil, criminal, administrative or investigative, to which any of them is a party by reason of his being a director, officer, employee, or agent of the Company if it is determined that he acted in accordance with the applicable standard of conduct set forth in such statutory provisions. Thus, the indemnification provisions will protect officers and directors from liability only if the officer or director meets the applicable standard of conduct and the Company has the financial ability to honor the indemnity.

ITEM 16. EXHIBITS.

The Exhibits to this Registration Statement are listed in the Exhibit Index commencing at page EX-1 hereof.

ITEM 17. UNDERTAKINGS.

The undersigned Registrant hereby undertakes the following:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

(i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) to reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information in this Registration Statement; and

(iii) to include any material information with respect to the plan of distribution not previously disclosed in this registration, or any material change to such information in the Registration Statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and

i

the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment to this Registration Statement any of the securities being registered which remain unsold at the termination of this offering.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers or persons controlling the Registrant pursuant to the General Corporation Law of Delaware, the Certificate of Incorporation, 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 such Act, 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 person controlling the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or person controlling the Registrant in connection with any 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 such Act and will be governed by the final adjudication of such issue.

SIGNATURES

Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all the requirements for filing on Form S-3 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of San Diego, State of California, on May 5, 2000.

the Investor or any affiliates of the Investor, for all Evaluation Days (as defined in Section 2.3.1(b) below) in the First Pricing Period (this limitation is referred to herein as the "First Volume Limitation"), where "X" shall equal the lesser of (x) 100,001 shares or (y) 25% of that day's Trading Volume, (ii) the Intended Put Share Amount, and (iii) the number of Put Shares which, when multiplied by their respective Put Share Prices, equals the Maximum Put Dollar Amount.

Notwithstanding the above, in no event shall the First Put Limit, the Second Put Limit, or the sum of the First Put Limit and the Second Put Limit (i) exceed the 9.9% Limitation, or (ii) exceed 20% of the sum of the aggregate daily reported Trading Volumes in the outstanding Common Stock on the Company's Principal Market, excluding any block trades which exceed "X" (as defined above) shares of Common Stock made by persons other than the Investor or any affiliates of the Investor, for the twenty (20) Trading Days immediately preceding the Put Date (this limitation, together with together with the First Volume Limitation and the Second Volume Limitation are referred to collectively as the "Volume Limitations"). The Company agrees not to trade Common Stock or arrange for Common Stock to be traded for the purpose of artificially increasing the Volume Limitations.

The "First Pricing Period" with respect to any Put shall mean the period of time beginning on the Business Day immediately following the Put Date for that Put, and ending on the First Pricing Date.

The "Second Pricing Period" with respect to any Put shall mean the period of time beginning on the Business Day immediately following the First Pricing Date and ending on the Second Pricing Date.

(e) Delivery of Put Notice. After delivery of an Advance Put Notice, on the Put Date specified in the Advance Put Notice, or on the sixth (6th) Business Day following the last day of the Second Pricing Period for the previous Put, whichever is later, the Company shall deliver written notice (the "Put Notice," the form of which is attached hereto as Exhibit G) to Investor stating (i) the Put Date, (ii) the Intended Put Share Amount as specified in the Advance Put Notice (such exercise a "Put"), (iii) the Company Designated Maximum Put Dollar Amount (if applicable), and (iv) the Company Designated Minimum Put Share Price (if applicable). In order to effect delivery of the Put Notice, the Company shall (i) send the Put Notice by facsimile on the Put Date so that such notice is received by the Investor by 6:00 p.m., New York, NY time, and (ii) surrender such notice on the Put Date to a courier for overnight delivery to the Investor (or two (2) day delivery in the case of a Investor residing outside of the U.S.). Upon receipt by the Investor of a facsimile copy of the Put Notice, the Investor shall, within two (2) Business Days, send, via facsimile, a confirmation of receipt (the "Put Notice Confirmation," the form of which is attached hereto as Exhibit H) of the Put Notice to Company specifying that the Put Notice has been received and affirming the Put Date and the Intended Put Share Amount.

(f) Delivery of Required Put Documents. On or before the Put Date for such Put, the Company shall deliver the Required Put Documents (as defined in Section 2.3.5 below) to the Investor (or to an agent of Investor, if Investor so directs). Unless otherwise specified by the Investor, the Put Shares of Common Stock shall be transmitted electronically pursuant to such electronic delivery system as the Investor shall request; otherwise delivery shall be by physical certificates. If the Company has not delivered all of the Required Put Documents to the Investor on or before the Put Date, the Put shall be automatically cancelled, unless the Investor agrees to delay the Put Date by up to three (3) Business Days, in which case the Pricing Period begins on the Business Day following such new Put Date. If the Company has not delivered all of the Required Put Documents to the Investor on or before the Put Date (or new Put Date, if applicable), and the Investor has not agreed in writing to delay the Put Date, the Put is automatically canceled (an "Impermissible Put Cancellation") and, unless the Put was otherwise canceled in accordance with the terms of Section 2.3.13, the Company shall pay the Investor $5,000 for its reasonable due diligence expenses incurred in preparation for the canceled Put and the Company may deliver an Advance Put Notice for the subsequent Put no sooner than ten (10) Business Days after the date that such Put was canceled.

(g) Limitation on Investor's Obligation to Purchase Shares. Notwithstanding anything to the contrary in this Agreement, in no event shall the Investor be required to purchase, and an Intended Put Share Amount may not include, an amount of Put Shares, which when added to the number of Put Shares acquired by the Investor pursuant to this Agreement during the 31 days preceding the Put Date with respect to which this determination of the permitted Intended Put Share Amount is being made, would exceed 9.99% of the number of shares of Common Stock outstanding (on a fully diluted basis, to the extent that inclusion of unissued shares is mandated by Section 13(d) of the Exchange Act) on the Put Date for such Pricing Period, as determined in accordance with
Section 13(d) of the Exchange Act (the "Section 13(d) Outstanding Share Amount"). Each Put Notice shall include a representation of the Company as to the Section 13(d) Outstanding Share Amount on the related Put Date. In the event that the Section 13(d) Outstanding Share Amount is different on any date during a Pricing Period than on the Put Date associated with such Pricing Period, then the number of shares of Common Stock outstanding on such date during such Pricing Period shall govern for purposes of determining whether the Investor, when aggregating all purchases

24

of Shares made pursuant to this Agreement in the 31 calendar days preceding such date, would have acquired more than 9.99% of the Section 13(d) Outstanding Share Amount. The limitation set forth in this Section 2.3.1(f) is referred to as the "9.9% Limitation."

27

statements contained therein, in light of the circumstances under which they were made, not misleading. If a Registration Opinion cannot be delivered by the Company's independent counsel to the Investor on the Registration Opinion Deadline due to the existence of Material Facts or an Ineffective Period, the Company shall promptly notify the Investor and as promptly as possible amend each of the Registration Statement and any Supplemental Registration Statement, as applicable, and any related prospectus or cause such Ineffective Period to terminate, as the case may be, and deliver such Registration Opinion and updated prospectus as soon as possible thereafter. If at any time after a Put Notice shall have been delivered to Investor but before the related Pricing Period End Date, the Company acquires knowledge of such Material Facts or any Ineffective Period occurs, the Company shall promptly notify the Investor and shall deliver a Put Cancellation Notice to the Investor pursuant to Section 2.3.13 by facsimile and overnight courier by the end of that Business Day.

(b) (i) the Company shall engage its independent auditors to perform the procedures in accordance with the provisions of Statement on Auditing Standards No. 71, as amended, as agreed to by the parties hereto, and reports thereon (the "Bring Down Cold Comfort Letters") as shall have been reasonably requested by the Investor with respect to certain financial information contained in the Registration Statement and shall have delivered to the Investor such a report addressed to the Investor, on the date that is three

In the event that the report required by this Section 2.3.6(b) cannot be delivered by the Company's independent auditors, the Company shall, if necessary, promptly revise the Registration Statement and the Company shall not deliver a Put Notice until such report is delivered.

2.3.7 Investor's Obligation and Right to Purchase Shares. Subject to the conditions set forth in this Agreement, following the Investor's receipt of a validly delivered Put Notice, the Investor shall be required to purchase (each a "Purchase") from the Company a number of Put Shares equal to the Put Share Amount, in the manner described below.

2.3.8 Mechanics of Put Closing. Each of the Company and the Investor shall deliver all documents, instruments and writings required to be delivered by either of them pursuant to this Agreement at or prior to each Closing. Subject to such delivery and the satisfaction of the conditions set forth in Sections 2.3.4 and 2.3.5, the closing of the purchase by the Investor of Put Shares shall occur by 5:00 PM, New York City Time, on the date which is five (5) Business Days following the last day of the Second Pricing Period for the applicable Put (the "Payment Due Date") at the offices of Investor. On each Closing Date, the Investor shall deliver to the Company, in the manner specified in Section 8 below, the Put Dollar Amount to be paid for such Put Shares, determined as aforesaid. The closing (each a "Put Closing") for each Put shall occur on the date that both (i) the Company has delivered to the Investor all Required Put

28

Documents, and (ii) the Investor has delivered to the Company such Put Dollar Amount and any Late Payment Amount, if applicable (each a "Put Closing Date").

If the Investor does not deliver to the Company the Put Dollar Amount for such Put on or before the Payment Due Date, then the Investor shall pay to the Company, in addition to the Put Dollar Amount, an amount (the "Late Payment Amount") at a rate of X% per month, accruing daily, multiplied by such Put Dollar Amount, where "X" equals one percent (1%) for the first month following the date in question, and increases by an additional one percent (1%) for each month that passes after the date in question, up to a maximum of five percent (5%).

2.3.9 [Intentionally Left Blank].

2.3.10 Limitation on Short Sales.

2.3.11 Cap Amount. If the Company becomes listed on the Nasdaq Small Cap Market or the Nasdaq National Market, then, unless the Company has obtained Stockholder 20% Approval as set forth in Section 6.12 or unless otherwise permitted by Nasdaq, in no event shall the Aggregate Issued Shares exceed the maximum number of shares of Common Stock (the "Cap Amount") that the Company can, without stockholder approval, so issue pursuant to Nasdaq Rule 4460(i)(1)(d)(ii) (or any other applicable Nasdaq Rules or any successor rule) (the "Nasdaq 20% Rule").

2.3.12  [Intentionally Left Blank]

2.3.13  Put Cancellation.

       (a) Mechanics of Put Cancellation. If at any time

during a Pricing Period the Company discovers the existence of Material Facts or any Ineffective Period or Delisting Event occurs, the Company shall cancel the Put (a "Put Cancellation"), by delivering written notice to the Investor (the "Put Cancellation Notice"), attached as Exhibit Q, by facsimile and overnight courier. The Company shall not be entitled to cancel a Put for any other reason except for the reasons set forth in the immediately preceding sentence. The "Put Cancellation Date" shall be the date that the Put Cancellation Notice is first received by the Investor, if such notice is received by the Investor by 6:00
p.m., New York, NY time, and shall be the following date, if such notice is received by the Investor after 6:00 p.m., New York, NY time.

(b) Effect of Put Cancellation. Anytime a Put Cancellation Notice is delivered to Investor during a Pricing Period, the Put shall remain effective for such Pricing Period with respect to a number of Put Shares (the "Truncated Put Share Amount") which shall equal the lesser of (i) 20% of the sum of the daily reported Trading Volume in the outstanding Common Stock on the Company's Principal Market during each Evaluation Day of the Truncated Pricing Period (as defined in Section 2.3.7(b)),

29

(ii) the number of Put Shares which, when multiplied by their respective Put Share Prices, equals the Maximum Put Dollar Amount, subject to the Individual Put Limit.

(c) Put Cancellation Notice Confirmation. Upon receipt by the Investor of a facsimile copy of the Put Cancellation Notice, the Investor shall promptly send, via facsimile, a confirmation of receipt (the "Put Cancellation Notice Confirmation," a form of which is attached as Exhibit S) of the Put Cancellation Notice to the Company specifying that the Put Cancellation Notice has been received and affirming the Put Cancellation Date.

(d) Truncated Pricing Period. If a Put Cancellation Notice has been delivered to the Investor, pursuant to Section 2.3.13 below, during a Pricing Period, that Pricing Period shall end at the close of trading on the last full trading day on the Principal Market that ends prior to the moment of initial delivery of the Put Cancellation Notice (a "Truncated Pricing Period") to the Investor.

2.3.14 Investment Agreement Cancellation. The Company may terminate (a "Company Termination") its right to initiate future Puts by providing written notice ("Termination Notice") to the Investor, by facsimile and overnight courier, at any time other than during an Extended Put Period, provided that such termination shall have no effect on the parties' other rights and obligations under this Agreement, the Registration Rights Agreement or the Warrants. Notwithstanding the above, any cancellation occurring during an Extended Put Period is governed by Section 2.3.13.

2.3.15 Return of Excess Common Shares. In the event that the number of Shares purchased by the Investor pursuant to its obligations hereunder is less than the Intended Put Share Amount, the Investor shall promptly return to the Company any shares of Common Stock in the Investor's possession that are not being purchased by the Investor.

2.4 Warrants.

2.4.1 [Intentionally Omitted].

2.4.2 Purchase Warrants. Within five (5) Business Days of the end of the Second Pricing Period for each Put, the Company shall issue and deliver to the Investor a warrant ("Purchase Warrant"), in the form attached hereto as Exhibit D, or such other form as agreed upon by the parties, to purchase a number of shares of Common Stock equal to 15% of the Put Share Amount for that Put. Each Purchase Warrant shall be exercisable at a price (the "Purchase Warrant Exercise Price") which shall initially equal 110% of the Closing Bid Price on the applicable Put Date, and shall have semi-annual reset provisions. Each Purchase Warrant shall be immediately exercisable at the Purchase Warrant Exercise Price, and shall have a term beginning on the date of issuance and ending on date that is five (5) years thereafter. The Warrant Shares shall be registered for resale pursuant to the Registration Rights Agreement. Concurrently with the issuance and delivery of the Purchase Warrant to the Investor, the Company shall deliver to the Investor a Purchase Warrant Opinion of Counsel (signed by the Company's independent counsel).

2.5 [Intentionally Left Blank].

2.6 Due Diligence Review. The Company shall make available for inspection and review by the Investor (the "Due Diligence Review"), advisors to and representatives of the Investor (who may or may not be affiliated with the Investor and who are reasonably acceptable to the Company), any underwriter participating in any disposition of Common Stock on behalf of the Investor pursuant to the Registration Statement, any Supplemental Registration Statement, or amendments or supplements thereto or any blue sky, NASD or other filing, all financial and other records, all SEC Documents and other filings with the SEC, and all other corporate documents and properties of the Company as may be reasonably necessary for the purpose of such review, and cause the Company's officers, directors and employees to supply all such information reasonably requested by the Investor or any such representative, advisor or underwriter in connection with such Registration Statement (including, without limitation, in response to all questions and other inquiries reasonably made or submitted by any of them), prior to and from time to time after the filing and effectiveness of the Registration Statement for the sole purpose of enabling the Investor and such representatives, advisors and underwriters and their respective accountants and attorneys to conduct initial and ongoing due diligence with respect to the Company and the accuracy of the Registration Statement.

2.6.1 Treatment of Nonpublic Information. The Company shall not disclose nonpublic information to the Investor or to its advisors or representatives unless prior to disclosure of such information the Company identifies such information as being nonpublic information and provides the Investor and such advisors and representatives with the opportunity to accept or refuse to accept such nonpublic information for review. The Company may, as a condition to disclosing any nonpublic information hereunder, require the Investor and its advisors and representatives to enter into a confidentiality agreement (including an agreement with such advisors and representatives prohibiting them from trading in Common Stock during such period of time as they are in possession of nonpublic information) in form reasonably satisfactory to the Company and the Investor.

Nothing herein shall require the Company to disclose nonpublic information to the Investor or its advisors or representatives, and the Company represents that it does not disseminate nonpublic information to any investors who purchase stock in the Company in a public offering, to money managers or to securities analysts, provided, however, that notwithstanding anything herein to the contrary, the Company will, as hereinabove provided, immediately notify the advisors and representatives of the Investor and, if any, underwriters, of any event or the existence of any circumstance (without any obligation to disclose the specific event or circumstance) of which it becomes aware, constituting nonpublic information (whether or not requested of the Company specifically or generally during the course of due diligence by and such persons or entities), which, if not disclosed in the Prospectus included in the Registration Statement, would cause such Prospectus to include a material misstatement or to omit a material fact required to be stated therein in order to make the statements therein, in light of the circumstances in which they were made, not misleading. Nothing contained in this Section 2.6 shall be construed to mean that such persons or entities other than the Investor (without the written consent of the Investor prior to disclosure of such information) may not obtain nonpublic information in the course of conducting due diligence in accordance with the terms of this Agreement; provided, however, that in no event shall the Investor's advisors or representatives disclose to the Investor the nature of the specific event or circumstances constituting any nonpublic information

31

discovered by such advisors or representatives in the course of their due diligence without the written consent of the Investor prior to disclosure of such information.

2.6.2 Disclosure of Misstatements and Omissions. The Investor's advisors or representatives shall make complete disclosure to the Investor's counsel of all events or circumstances constituting nonpublic information discovered by such advisors or representatives in the course of their due diligence upon which such advisors or representatives form the opinion that the Registration Statement contains an untrue statement of a material fact or omits a material fact required to be stated in the Registration Statement or necessary to make the statements contained therein, in the light of the circumstances in which they were made, not misleading. Upon receipt of such disclosure, the Investor's counsel shall consult with the Company's independent counsel in order to address the concern raised as to the existence of a material misstatement or omission and to discuss appropriate disclosure with respect thereto; provided, however, that such consultation shall not constitute the advice of the Company's independent counsel to the Investor as to the accuracy of the Registration Statement and related Prospectus.

2.6.3 Procedure if Material Facts are Reasonably Believed to be Untrue or are Omitted. In the event after such consultation the Investor or the Investor's counsel reasonably believes that the Registration Statement contains an untrue statement or a material fact or omits a material fact required to be stated in the Registration Statement or necessary to make the statements contained therein, in light of the circumstances in which they were made, not misleading,

(a) the Company shall file with the SEC an amendment to the Registration Statement responsive to such alleged untrue statement or omission and provide the Investor, as promptly as practicable, with copies of the Registration Statement and related Prospectus, as so amended, or

(b) if the Company disputes the existence of any such material misstatement or omission, (i) the Company's independent counsel shall provide the Investor's counsel with a Registration Opinion and
(ii) in the event the dispute relates to the adequacy of financial disclosure and the Investor shall reasonably request, the Company's independent auditors shall provide to the Company a letter ("Agreed Upon Procedures Report") outlining the performance of such "agreed upon procedures" as shall be reasonably requested by the Investor and the Company shall provide the Investor with a copy of such letter.

2.7 Commitment Payments. On each six (6) month anniversary of the Investment Commitment Closing, if the Investor has not received at least an amount equal to the applicable Semi-Annual Commitment Fee, as set forth below, in aggregate Gross Discount Amounts for the preceding six (6) Calendar Months (each such period a "Commitment Evaluation Period"), the Company, in consideration of Investor's commitment costs, including, but not limited to, due diligence expenses, shall pay to the Investor an amount (the "Semi-Annual Commitment Shortfall") equal to the difference of (i) the applicable Semi-Annual Commitment Fee, as defined below, minus (ii) the aggregate of the Gross Discount Amounts received by the Investor during the preceding six (6) Calendar Months. In the event that the Company delivers a Termination Notice to the Investor, the Company shall pay to the Investor the greater of (i) the Semi-Annual Commitment

32

Fee for the applicable Commitment Evaluation Period, less the Gross Discount Amount on amounts put to the Investor in that Commitment Evaluation Period, or
(ii) the difference of (x) $200,000, minus (y) the aggregate of the Gross Discount Amounts for all Puts to date, and the Company shall not be required to pay the Semi-Annual Commitment Shortfall thereafter.

For purposes hereof, the Semi-Annual Commitment Fee shall be as follows:

       Commitment Evaluation Period                        Semi-Annual Commitment Fee
       ----------------------------                        --------------------------
First 6 Calendar Months after Closing*                              $50,000**
 6 through 12 Calendar Months after Closing                          $75,000
12 through 18 Calendar Months after Closing                          $100,000
18 through 24 Calendar Months after Closing                          $100,000
24 through 30 Calendar Months after Closing                          $125,000
30 through 36 Calendar Months after Closing                          $150,000

* = Investment Commitment Closing

** = If the date of effectiveness of the Registration Statement is more than 4 Calendar Months after the date of filing of the Registration Statement, and the Company has used its best efforts to cause such Registration Statement to become effective as soon as possible, the Semi-Annual Commitment Fee for the First 6 Calendar Months After Closing shall be reduced to $25,000.

The Company shall not be required to deliver any payments to Investor under this subSection until Investor has paid all Put Dollar Amounts that are then due.

The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to a Investor by vitiating the intent and

45

purpose of the transaction contemplated hereby. Accordingly, the Company acknowledges that the remedy at law for a breach of its obligations under this
Section 6.11 will be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions of this Section 6.11, that a Investor shall be entitled, in addition to all other available remedies, to an injunction restraining any breach and requiring immediate issuance and transfer, without the necessity of showing economic loss and without any bond or other security being required.

7.3 Execution in Counterparts Permitted. This Agreement may be executed in any number of counterparts, each of which shall be enforceable against the parties actually executing such counterparts, and all of which together shall constitute one (1) instrument.

7.4 Titles and Subtitles; Gender. The titles and subtitles used in this Agreement are used for convenience only and are not to be considered in construing or interpreting this Agreement.

A proceeding shall be commenced upon written demand by Company or any Investor to the other. The arbitrator(s) shall enter a judgment by default against any party, which fails or refuses to appear in any properly noticed

47

arbitration proceeding. The proceeding shall be conducted by one (1) arbitrator, unless the amount alleged to be in dispute exceeds two hundred fifty thousand dollars ($250,000), in which case three (3) arbitrators shall preside. The arbitrator(s) will be chosen by the parties from a list provided by the AAA, and if they are unable to agree within ten (10) days, the AAA shall select the arbitrator(s). The arbitrators must be experts in securities law and financial transactions. The arbitrators shall assess costs and expenses of the arbitration, including all attorneys' and experts' fees, as the arbitrators believe is appropriate in light of the merits of the parties' respective positions in the issues in dispute. Each party submits irrevocably to the jurisdiction of any state court sitting in Wilmington, Delaware or to the United States District Court sitting in Delaware for purposes of enforcement of any discovery order, judgment or award in connection with such arbitration. The award of the arbitrator(s) shall be final and binding upon the parties and may be enforced in any court having jurisdiction. The arbitration shall be held in such place as set by the arbitrator(s) in accordance with Rule 55.

Although the parties, as expressed above, agree that all claims, including claims that are equitable in nature, for example specific performance, shall initially be prosecuted in the binding arbitration procedure outlined above, if the arbitration panel dismisses or otherwise fails to entertain any or all of the equitable claims asserted by reason of the fact that it lacks jurisdiction, power and/or authority to consider such claims and/or direct the remedy requested, then, in only that event, will the parties have the right to initiate litigation respecting such equitable claims or remedies. The forum for such equitable relief shall be in either a state or federal court sitting in Wilmington, Delaware. Each party waives any right to a trial by jury, assuming such right exists in an equitable proceeding, and irrevocably submits to the jurisdiction of said Delaware court. Delaware law shall govern both the proceeding as well as the interpretation and construction of the Transaction Documents and the transaction as a whole.

8. Subscription and Wiring Instructions; Irrevocability.

8.1 Subscription

(a) Wire transfer of Subscription Funds. Investor shall deliver Put Dollar Amounts (as payment towards any Put Share Price) by wire transfer, to the Company pursuant to a wire instruction letter to be provided by the Company, and signed by the Company.

(b) Irrevocable Subscription. Investor hereby acknowledges and agrees, subject to the provisions of any applicable laws providing for the refund of subscription amounts submitted by Investor, that this Agreement is irrevocable and that Investor is not entitled to cancel, terminate or revoke this Agreement or any other agreements executed by such Investor and delivered pursuant hereto, and that this Agreement and such other agreements shall survive the death or disability of such Investor and shall be binding upon and inure to the benefit of the parties and their heirs, executors, administrators, successors, legal representatives and assigns. If the Securities subscribed for are to be owned by more than one person, the obligations of all such owners under this Agreement shall be joint and several, and the agreements, representations, warranties and acknowledgments herein contained shall be deemed to be made by and be binding upon each such person and his heirs, executors,

48

administrators, successors, legal representatives and assigns.

8.2 Acceptance of Subscription. Ownership of the number of securities purchased hereby will pass to Investor upon the Warrant Closing or any Put Closing.

8.3 [Intentionally Omitted]

9. Indemnification.

In consideration of the Investor's execution and delivery of the Investment Agreement, the Registration Rights Agreement and the Warrants (the "Transaction Documents") and acquiring the Securities thereunder and in addition to all of the Company's other obligations under the Transaction Documents, the Company shall defend, protect, indemnify and hold harmless Investor and all of its stockholders, officers, directors, employees and direct or indirect investors and any of the foregoing person's agents, members, partners or other representatives (including, without limitation, those retained in connection with the transactions contemplated by this Agreement) (collectively, the "Indemnitees") from and against any and all actions, causes of action, suits, claims, losses, costs, penalties, fees, liabilities and damages, and expenses in connection therewith (irrespective of whether any such Indemnitee is a party to the action for which indemnification hereunder is sought), and including reasonable attorney's fees and disbursements (the "Indemnified Liabilities"), incurred by any Indemnitee as a result of, or arising out of, or relating to (a) any misrepresentation or breach of any representation or warranty made by the Company in the Transaction Documents or any other certificate, instrument or documents contemplated hereby or thereby, (b) any breach of any covenant, agreement or obligation of the Company contained in the Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby, or
(c) any cause of action, suit or claim, derivative or otherwise, by any stockholder of the Company based on a breach or alleged breach by the Company or any of its officers or directors of their fiduciary or other obligations to the stockholders of the Company.

To the extent that the foregoing undertaking by the Company may be unenforceable for any reason, the Company shall make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities which it would be required to make if such foregoing undertaking was enforceable which is permissible under applicable law.

Promptly after receipt by an Indemnified Party of notice of the commencement of any action pursuant to which indemnification may be sought, such Indemnified Party will, if a claim in respect thereof is to be made against the other party (hereinafter "Indemnitor") under this Section 9, deliver to the Indemnitor a written notice of the commencement thereof and the Indemnitor shall have the right to participate in and to assume the defense thereof with counsel reasonably selected by the Indemnitor, provided, however, that an Indemnified Party shall have the right to retain its own counsel, with the reasonably incurred fees and expenses of such counsel to be paid by the Indemnitor, if representation of such Indemnified Party by the counsel retained by the Indemnitor would be inappropriate due to actual or potential conflicts of interest between such Indemnified Party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the Indemnitor within a reasonable time of the commencement of any such

49

action, if prejudicial to the Indemnitor's ability to defend such action, shall relieve the Indemnitor of any liability to the Indemnified Party under this
Section 9, but the omission to so deliver written notice to the Indemnitor will not relieve it of any liability that it may have to any Indemnified Party other than under this Section 9 to the extent it is prejudicial.
