PART I FINANCIAL INFORMATION

A CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS. Except for historical information contained herein, this Quarterly Report on Form 10-Q contains certain forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. In light of the important factors that can materially affect results, including those set forth elsewhere in this Form 10-Q, the inclusion of forward-looking information should not be regarded as a representation by the Company or any other person that the objectives or plans of the Company will be achieved. We will encounter competitive, technological, financial and business challenges making it more difficult than expected to continue to develop, market and manufacture our products. Our challenges may include, but are not limited to, competitive conditions within the industry, which may change adversely; upon development of our products, demand for our products may weaken; the market may not accept our products; we may not be able to retain existing key management personnel; our forecasts may not accurately anticipate market demand; and there may be other material adverse changes in our operations or business. In addition, certain important factors affecting the forward-looking statements made herein include, but are not limited to, the risks and uncertainties associated with completing pre-clinical and clinical trials for our technologies; obtaining additional financing to support our operations; obtaining regulatory approval for our technologies; complying with other governmental regulations applicable to our business; obtaining the raw materials necessary in the development of such compounds; consummating collaborative arrangements with corporate partners for product development; achieving milestones under collaborative arrangements with corporate partners; developing the capacity to manufacture, market and sell our products, either directly or indirectly with collaborative partners; developing market demand for and acceptance of such products; competing effectively with other pharmaceutical and biotechnological products; attracting and retaining key personnel; protecting proprietary rights; accurately forecasting operating and capital expenditures, other commitments, or clinical trial costs, general economic conditions and other factors. The assumptions relating to budgeting, marketing, product development and other management decisions are subjective in many respects and thus susceptible to interpretations and periodic revisions based on actual experience and business developments, the impact of which may cause us to alter our capital expenditure or other budgets, which may in turn affect our business, financial position and our results of operations.

TECHNICLONE CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS FOR THE NINE MONTHS ENDED JANUARY 31, 1999 (UNAUDITED)

1) SUMMARY OF OUR SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION. The accompanying unaudited financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. As shown in the financial statements, the Company experienced losses in fiscal 1998 and during the first nine months of fiscal 1999 and has an accumulated deficit of $84,429,000 at January 31, 1999. These factors, among others, raise substantial doubt about the Company's ability to continue as a going concern.

The Company must raise additional funds to sustain research and development, provide for future clinical trials and continue its operations until it is able to generate sufficient additional revenue from the sale and/or licensing of its products. The Company plans to obtain required financing through one or more methods including, obtaining additional equity or debt financing and negotiating additional licensing or collaboration agreements with another company. There can be no assurance that the Company will be successful in raising such funds on terms acceptable to it, or at all, or that sufficient additional capital will be raised to complete the research, development, and clinical testing of the Company's product candidates. The Company's future success is dependent upon raising additional money to provide for the necessary operations of the Company. If the Company is unable to obtain additional financing, there would be a material adverse effect on the Company's business, financial position and results of operations. The Company's continuation as a going concern is dependent on its ability to generate sufficient cash flow to meet its obligations on a timely basis, to obtain additional financing as may be required and, ultimately, to attain successful operations.

At January 31, 1999, the Company had cash and cash equivalents of $240,000. On February 2, 1999, the Company exercised its Put option and received gross proceeds of $2,250,000 in exchange for 2,869,564 shares of common stock pursuant to a Regulation D Common Stock Equity Line Subscription Agreement the (the "Equity Line Agreement") (Notes 3 and 5). In addition, on March 8, 1999, the Company entered into a licensing agreement with an unrelated entity for the licensing of Oncolym(R) in exchange for an up-front license payment of $3,000,000 (Note 5). The Company believes it has sufficient cash on hand and available pursuant to the Equity Line Agreement (assuming only one future quarterly draw of $2,250,000 in May 1999) to meet its obligations on a timely basis through June 1999. Management believes that additional capital must be raised to support the Company's continued operations and other short-term cash needs.

See accompanying notes to consolidated financial statements

FOR THE NINE MONTHS ENDED JANUARY 31, 1999 (UNAUDITED) (CONTINUED)

The Company's ability to access funds under the Equity Line Agreement is subject to the satisfaction of certain conditions and the failure to satisfy these conditions may limit or preclude the Company's ability to access such funds, which could adversely affect the Company's business, immediate liquidity, financial position and results of operations unless additional financing sources are available.

The accompanying unaudited consolidated financial statements contain all adjustments (consisting of only normal recurring adjustments) which, in the opinion of management, are necessary to present fairly the consolidated financial position of the Company at January 31, 1999, and the consolidated results of its operations and its consolidated cash flows for the three and nine month periods ended January 31, 1999 and 1998. Although the Company believes that the disclosures in the financial statements are adequate to make the information presented not misleading, certain information and footnote disclosures normally included in the consolidated financial statements have been condensed or omitted pursuant to rules and regulations of the Securities and Exchange Commission. The consolidated financial statements included herein should be read in conjunction with the consolidated financial statements of the Company, included in the Company's Annual Report on Form 10-K for the year ended April 30, 1998, filed with the Securities and Exchange Commission on July 29, 1998.

Certain reclassifications were made to the 1998 balances to conform them to the 1999 presentation.

Results of operations for the interim periods covered by this Report may not necessarily be indicative of results of operations for the full fiscal year.

NET LOSS PER SHARE. Net loss per share is calculated by adding the net loss for the quarter and nine month period to the Preferred Stock dividends and Preferred Stock issuance discount accretion on the Class B Preferred Stock and the Class C Preferred Stock during the quarter and nine month period divided by the weighted average number of shares of common stock outstanding during the quarter and nine month period. Shares issuable upon the exercise of common stock warrants and options have been excluded from the quarter and nine month period ended January 31, 1999 and 1998 per share calculation because their effect is antidilutive. Accretion of the Class B and Class C Preferred Stock dividends and issue discount amounted to $3,000 and $987,000 for the quarter ended January 31, 1999 and 1998, respectively, and $545,000 and $3,147,000 for the nine month periods ended January 31, 1999 and 1998, respectively.

NEW ACCOUNTING STANDARDS. In May 1998, the Company adopted Statement of Financial Accounting Standards (SFAS) No. 130, "Reporting Comprehensive Income". SFAS No. 130 established standards for the reporting and displaying of comprehensive income. Comprehensive income is defined as all changes in a Company's net assets except changes resulting from transactions with shareholders. It differs from net income in that certain items currently recorded to equity would be a part of comprehensive income. The adoption of this standard had no effect on the Company's consolidated financial statements.

The Company adopted Financial Accounting Standards Board (SFAS) No. 131, "Disclosure about Segments of an Enterprise and Related Information" on May 1, 1998. SFAS No. 131 established standards of reporting by publicly held businesses and disclosures of information about operating segments in annual financial statements, and to a lesser extent, in interim financial reports issued to shareholders. The adoption of SFAS No. 131 had no impact on the Company's consolidated unaudited financial statements or related disclosures for the three and nine month periods ended January 31, 1999 and 1998.

During June 1998, the Financial Accounting Standards Board issued SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities" which will be effective for the Company beginning April 1, 2000. SFAS No. 133 establishes accounting and reporting standards for derivative instruments, including certain derivative instruments imbedded in other contracts, and for hedging activities. It requires that an entity recognize all derivatives as either assets or liabilities in the statements of financial position and measure those instruments at fair value. The Company has not determined the impact on the consolidated financial statements, if any, upon adopting SFAS No. 133.

2) PROPERTY

On December 24, 1998, the Company completed the sale and subsequent leaseback of its two facilities located in Tustin, California with an unrelated entity (buyer/landlord). The aggregate sales price of the two facilities was $6,100,000, which was comprised of $4,175,000 in cash and a note receivable for $1,925,000. In connection with the sale/leaseback transaction, the Company recorded a non-cash loss on disposal of property of approximately $1,171,000, included in the accompanying consolidated financial statements.

The note receivable of $1,925,000, included in other assets in the accompanying consolidated financial statements, bears interest at a rate of 7% per annum and is collaterized under the Pledge and Security Agreement dated December 24, 1998. Principal and interest payments of $15,441 are due monthly based on a 20-year amortization. The note receivable is due upon the earlier of the sale of the property or at the end of the initial lease term of twelve years.

The leaseback is a Triple Net Lease, whereas the Company is responsible for all expenses incurred in the maintenance of the building including property taxes and insurance. The initial lease term is twelve years with two five-year extension options. The initial base rent is $56,250 per month, with rent increases of 3.35% every two years.

Concurrent with the sale/leaseback transaction, the Company borrowed $200,000 from the buyer/landlord. The note payable bears interest at 7% per annum and is uncollateralized. Principal and interest payments of $6,175 are due monthly through December 2001.

3) STOCKHOLDERS' EQUITY

During June 1998, the Company secured access of up to $20,000,000 under the Equity Line Agreement, expiring in June 2001. Under the terms of the Equity Line Agreement, the Company may, in its sole discretion, and subject to certain restrictions, periodically sell (Put) shares of the Company's common stock for up to $20,000,000 upon the effective registration of the Put shares, which occurred on January 15, 1999. After effective registration for the Put shares, unless an increase is otherwise agreed to, $2,250,000 of Puts can be made every quarter, subject to share issuance volume limitations identical to those set forth in Rule 144(e). At the time of each Put, the investors will be issued a warrant, expiring on December 31, 2004, to purchase up to 10% of the amount of common stock issued to the investor at the same price at the time of the Put.

Also in June 1998, the Company sold 2,749,090 shares of the Company's common stock under the Equity Line Agreement, including commission shares, for gross proceeds to the Company of $3,500,000. One-half of this amount ($1,750,000) is subject to adjustment on April 15, 1999 or three months after the effective date of the registration statement registering these shares with the second half ($1,750,000) subject to adjustment on July 15, 1999 or six months after such effective date of the registration of these shares (the "Reset Provision"). At each adjustment date, if the market price at the three or six month period ("Adjustment Price") is less than the initial price paid for the common stock, the Company will be required to issue additional shares of its common stock equal to the difference between the amount of shares which would have been issued if the price had been the Adjustment Price for $1,750,000. The Company will also be required to issue additional warrants at each three month and six month period for 10% of any additional shares issued.

Future Puts under the Equity Line will be priced at (i) 82.5% of the lowest closing bid price during the ten trading days (the "10 day low closing bid price") immediately preceding the date on which such shares are sold to the Institutional Investors, or (ii) if 82.5% of such 10 day low closing bid price results in a discount of less than twenty cents ($0.20) per share from such 10 day low closing bid price, such 10 day low closing bid price minus twenty cents ($0.20).

In December 1998, the Company issued an additional 156,570 shares of common stock under the Equity Line related to the initial $3,500,000 tranche for mutual consideration.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
FOR THE NINE MONTHS ENDED JANUARY 31, 1999 (UNAUDITED) (CONTINUED)

On February 2, 1999, the Company exercised a Put option under the Equity Line Agreement and received gross proceeds of $2,250,000 in exchange for 2,869,564 shares of common stock, including commission shares. As of March 1, 1999, the Company had $14,250,000 available for future Puts under the Equity Line Agreement pursuant to the terms in the agreement.

If the Company does not exercise the full amount of its Put rights, then the Company will issue Commitment Warrants on the first, second, and third anniversary of the Equity Line Agreement. The number of Commitment Warrants to be issued on each anniversary date will be equal to ten percent (10%) of the quotient of the difference of $6,666,666, $13,333,333 and $20,000,000 (Commitment Amounts), respectively, less the actual cumulative total dollar amount of Puts which have been exercised by the Company prior to such anniversary date divided by the market price of the Company's common stock.

In accordance with the Emerging Issues Task Force Issue No. 96-13, "Accounting for Derivative Financial Instruments", contracts that require a company to deliver shares as part of a physical settlement should be measured at the estimated fair value on the date of the initial Put. As such, the Company had an independent appraisal performed to determine the estimated fair market value of the various financial instruments included in the Equity Line Agreement and recorded the related financial instruments as reclassifications between equity categories. Reclassifications were made for the estimated fair market value of the warrants issued and estimated Commitment Warrants to be issued under the Equity Line of $1,140,000 and the estimated fair market value of the Reset Provision of $400,000 as additional consideration and have been included in the accompanying unaudited financial statements. The above recorded amounts were offset by $700,000 related to the restrictive nature of the common stock issued under the initial tranche in June 1998 and the estimated fair market value of the Equity Line Put Option of $840,000.

4) COMMITMENTS

In July 1998, the Company renegotiated a severance agreement with its former Chief Executive Officer (CEO). The Company's former CEO's employment agreement provided that the Company make immediate and substantial cash expenditure upon his termination. The Company did not have sufficient cash resources to fulfill its obligations under the former CEO's employment agreement. Accordingly, at the direction of the Board of Directors, the Company negotiated a new Severance Agreement with its former CEO to conserve cash. The new Severance Agreement provides for its former CEO to be paid $300,000 a year for the period beginning March 1, 1998 through March 1, 2000. Unexercised and unvested outstanding stock options on March 1, 1998, will vest and be paid as follows: one-third of the unexercised, unvested options outstanding on March 1, 1998 will vest immediately and be paid to the former CEO on December 31, 1998; one-third of the unexercised, unvested and outstanding options on March 1, 1998, will vest on March 1, 1999 and be paid on December 31, 1999; and one-third of

the unexercised, unvested and outstanding options on March 1, 1998, will vest and be paid on March 1, 2000. In addition, the Company will make appropriate payments, at the bonus rate, to the appropriate taxing authorities. During the employment period, beginning on March 1, 1998 and ending on March 1, 2000, the former CEO will, with certain exceptions, be eligible for Company benefits. Pursuant to the Severance Agreement, the former CEO will be available to work for the Company for a minimum of 25 hours per week. In addition, as part of the former CEO's agreement to modify his existing severance package, the Company agreed that if the former CEO did not compete during the period beginning March 1, 1998 and ending February 29, 2000, the Company will, on March 1, 2000, pay the former CEO an amount equal to his note of $350,000, plus all accrued interest thereon, which will be used to retire the respective note. During the nine months ended January 31, 1999, the Company expensed approximately $756,000 for related severance pay which has been included in general and administrative expenses in the accompanying consolidated financial statements.

On October 4, 1998, Mr. William Moding resigned from his position as Vice President, Operations and Administration to pursue other personal and business interests. In connection with Mr. Moding's resignation, the Company entered into a revised severance agreement with Mr. Moding pursuant to which Mr. Moding will provide consulting services to the Company as an independent consultant for a fixed and non-cancelable period of sixteen months continuing until January 31, 2000, in consideration of the payment to Mr. Moding of a monthly consulting fee of $12,500 and the issuance of an aggregate of 320,000 shares of Common Stock during such period for the exercise of outstanding stock options, without the requirement of any payment by Mr. Moding of the exercise price ($.60 per share). In addition, the Company has agreed to make tax payments totaling $65,280 to federal and state taxing authorities on behalf of Mr. Moding to offset the income to Mr. Moding resulting from the non-payment of the exercise price for such options and to pay Mr. Moding all accrued and unused vacation pay and accrued back pay relating to salary deferral for the period from March 21, 1998 through October 3, 1998. Pursuant to the revised agreement, Mr. Moding will be required to repay the Company the entire outstanding principal balance and accrued interest thereon under two stock option exercise notes by no later than January 31, 2000 and to execute a standard form security agreement relating to the stock option exercise notes to pledge Mr. Moding's interest in the stock options and his personal assets as backup collateral to secure his obligations under the two stock option exercise notes. From inception of the revised severance agreement through January 31, 1999, the Company expensed approximately $259,000 for related severance costs, which has been included in general and administrative expenses in the accompanying consolidated financial statements.

5) SUBSEQUENT EVENTS

On February 2, 1999, the Company exercised a Put option under the Equity Line Agreement and received gross proceeds of $2,250,000 in exchange for 2,869,564 shares of common stock, including commission shares. As of March 1, 1999, the Company had $14,250,000 available for future Put under the Equity Line Agreement pursuant to the terms in the agreement (Note 3).

On March 8, 1999, the Company entered into a Termination Agreement with Biotechnology Development, Ltd. ("BTD"), pursuant to which the Company terminated all previous agreements with BTD and thereby reacquired the marketing rights to LYM products in Europe and certain other designated foreign countries, in exchange for (i) the issuance to BTD of a Secured Promissory Note in the principal face amount of $3,300,000 bearing simple interest at the rate of ten percent (10%) per annum, with interest payable monthly in advance and the full principal amount due and payable on March 1, 2001, (ii) the issuance of warrants to purchase up to 3,700,000 shares of Common Stock at an exercise price of $3.00 per share exercisable for a period of three (3) years, (iii) the issuance of warrants to purchase up to 1,000,000 shares of Common Stock at an exercise price of $5.00 per share exercisable for a period of five (5) years and (iv) the issuance of shares of Common Stock equal in value to $1,200,000, based on a value per share equal to ninety percent (90%) of the market price of the common stock. Pursuant to a related Security Agreement, the Company granted a security interest to BTD in and to all assets of the Company, excluding inventory, furniture, fixtures and equipment which are used in the commercialization of Oncolym(R) which are not located on the Company's Tustin, California premises or which serve as security to any other entity and further excluding any and all intangible property and intellectual property of the Company and any and all rights with respect thereto and any goodwill associated therewith.

Also on March 8, 1999, the Company entered into a License Agreement with Schering AG, Germany. Under the terms of the agreement, Schering AG, Germany was granted the exclusive, worldwide right to market and distribute LYM products in exchange for an initial payment of $3,000,000, a further payment of $2,000,000 following the acceptance by the FDA for filing of the first drug approval application for Oncolym(R) in the United States, a further payment of $7,000,000 following regulatory approval of Oncolym(R) in the United States and two final payments of $2,500,000 each following regulatory approval of Oncolym(R) in any country in Europe and upon the first commercial sale of Oncolym(R) in any country in Europe. The Company will also receive a royalty equal to twelve percent (12%) of net sales of Oncolym(R) products (which is subject to reduction, on a country-by-country basis, to six percent (6%) if there is a generic form of the Oncolym(R) product being sold in such country), which may be reduced by one percentage point if the FDA does not consent to an extension of the existing Phase II trials of Oncolym(R) as a Phase III clinical trial by June 30, 1999. Pursuant to the terms of the agreement, the Company is required to pay for all pre-clinical expenses up to $500,000 incurred after March 8, 1999, and fifty percent (50%) of all such expenses incurred in excess of $500,000, with the other fifty percent of such expenses to be paid by Schering AG, Germany. The Company is also required to pay for twenty percent (20%) of the clinical development expenses and existing trial expenses associated with Oncolym(R), and Schering AG, Germany is required to pay for the other eighty percent (80%) of such expenses. Each party will pay for all of its

internal costs relating to existing trials. Pursuant to the agreement, the Company and Schering AG, Germany have also agreed to a structure for proceeding with negotiations concerning the terms of a possible licensing of the Company's Vascular Targeting Agent ("VTA") technology in the near future. The continued effectiveness of the agreement with Schering AG, Germany is subject to certain other conditions and may be terminated by Schering AG, Germany if (i) there are issues of safety or patient tolerability, (ii) Schering AG, Germany determines in its reasonable scientific or business discretion prior to receiving regulatory approval that the Oncolym(R) product is not acceptable for reasons of efficacy or risk/benefit therapeutic ratio, (iii) the FDA does not permit the extension or conversion of the Phase II trials of Oncolym(R) as a Phase III clinical trial by June 30, 1999, (iv) Schering AG, Germany determines, using its reasonable judgment based on data from or the results of the first Phase III clinical trials of Oncolym(R) that such results do not support the submission of Oncolym(R) for regulatory approval, (v) the Company fails to deliver or it becomes reasonably clear that the Company will fail to deliver in time appropriate quantities of clinical supplies of antibody or Oncolym(R) product such that the clinical development of Oncolym(R) will be delayed by three (3) months or more, (vi) if the Company has not concluded a definitive agreement providing for a radiolabeling site for the production of Oncolym(R) products by September 1, 1999, or (vii) at any time after receiving regulatory approval upon twelve months notice to the Company. However, if the agreement is terminated by Schering AG, Germany due to issues of safety or patient tolerability, or Schering AG, Germany determines in its reasonable scientific or business discretion prior to receiving regulatory approval that the Oncolym(R) product is not acceptable for reasons of efficacy or risk/benefit therapeutic ratio or determines, using its reasonable judgment based on data from or the results of the first Phase III clinical trials of Oncolym(R), that such results do not support the submission of Oncolym(R) for regulatory approval, Schering AG, Germany will remain obligated to pay for 80% of the non-cancellable third party costs in regard to clinical trials underway at the time of such termination, up to $1,500,000 (other than a termination after receiving regulatory approval). Schering AG, Germany may also terminate the agreement upon thirty days' written notice given at any time prior to receiving regulatory approval, but will remain obligated to pay for all of the costs of completing all then ongoing clinical trials for Oncolym(R), up to $3,000,000.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL

CONDITION AND RESULTS OF OPERATIONS

GOING CONCERN. The accompanying financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. As shown in the financial statements, we experienced losses in fiscal 1998 and during the first nine months of fiscal 1999 and we have an accumulated deficit at January 31, 1999 of $84,429,000. These factors, among others, raise substantial doubt about our ability to continue as a going concern.

We must raise additional funds to sustain research and development, provide for future clinical trials and continue our operations until we are able to achieve profitability based on revenue from the sale and/or licensing of its products. We plan to obtain required financing through one or more methods including, obtaining additional equity or debt financing and negotiating additional licensing or collaboration agreements with another company. There can be no assurance that we will be successful in raising such funds on terms acceptable to us, or at all, or that sufficient additional capital will be raised to complete the research, development, and clinical testing of our product candidates. Our future success is dependent upon raising additional money to provide for the necessary operations of the Company. If we are unable to obtain additional financing, there would be a material adverse effect on the Company's business, financial position and results of operations. Our continuation as a going concern is dependent on our ability to generate sufficient cash flow to meet our obligations on a timely basis, to obtain additional financing as may be required and, ultimately, to attain successful operations.

Management believes that additional capital must be raised to support the Company's continued operations and other short-term cash needs. The Company believes that it has sufficient cash on hand and available pursuant to the financing commitments under the Equity Line of Credit (assuming only one future quarterly draw of $2,250,000 in May 1999) to meet its obligations on a timely basis through June 1999. Our ability to access funds under the Equity Line Agreement is subject to the satisfaction of certain conditions and the failure to satisfy these conditions may limit or preclude the Company's ability to access such funds, which could adversely affect the our business, immediate liquidity, financial position and results of operations unless additional financing sources are available.

COMPANY OVERVIEW. We are engaged in the research, development and commercialization of novel cancer therapeutics in two principal areas - direct tumor targeting agents for the treatment of refractory malignant lymphoma and collateral tumor targeting agents for the treatment of solid tumors.

DIRECT TUMOR TARGETING AGENTS. Our most advanced direct tumor targeting agent candidate, Oncolym(R), is an investigational murine monoclonal antibody radiolabeled with I131 which is being studied in a Phase II/III trial for the treatment of intermediate and high-grade relapsed or refractory B-cell non-Hodgkins lymphoma ("NHL"). The clinical trials for Oncolym(R) are currently being held at participating medical centers, including M.D. Anderson Cancer Center, George Washington University Medical Center, Iowa City VA Medical Center, Queen's Medical Center-Hawaii, University of Illinois at Chicago Medical Center, The Medical University of South Carolina, Beth Israel Deaconess Medical Center-Boston, Cleveland Clinic and University of Miami Hospital. We currently anticipate adding up to eight additional clinical trial sites for Oncolym(R). Following the completion of the clinical trials, we expect to file an application with the United States Food and Drug Administration ("FDA") to market Oncolym(R) in the United States.

18

COLLATERAL TUMOR TARGETING AGENTS. Collateral tumor targeting may be described as the therapeutic strategy of targeting peripheral structures and cell types, other than the viable cancer cells directly, as a means to treat solid tumors. Our three leading advanced collateral targeting agents for solid tumors are Tumor Necrosis Therapy ("TNT"), Vascular Targeting Agents ("VTAs"), and Vasopermeation Enhancement Agents ("VEAs").

o TNT is a universal tumor targeting therapy potentially capable of treating a wide range of solid tumors. Radiolabeled TNT agents are believed to act by binding to dead or dying cells at the core of the tumor and irradiating the tumor from the inside out. TNT is potentially capable of carrying a wide variety of therapeutic agents to the interior of solid tumors. Our first TNT-based product is an investigational, chimeric monoclonal antibody radiolabeled with the I131 isotope. During March 1998, we began enrolling patients into a Phase I study of TNT for the treatment of malignant glioma (brain cancer). We have since filed a protocol with the FDA for a Phase II study of TNT for the treatment of malignant glioma, which commenced in December 1998. The clinical trials are currently being conducted at The Medical University of South Carolina with additional clinical sites underway. We have also received an unrestricted grant to conduct Phase I/II systemic trials of TNT for prostate, pancreatic and liver cancers at a clinical site in Mexico City.

o VTAs are believed to act by destroying the vasculature of solid tumors. VTAs are multi-functional molecules that target the capillaries and blood vessels of solid tumors. Once there, these agents block the flow of oxygen and nutrients to the underlying tissue by creating a blood clot in the tumor. In preclinical trials, VTAs have caused clots in animals and within hours of the clot's formation, the tumor begins to die and necrotic regions are formed. Since every tumor in excess of 2mm in size forms an expanding vascular network during tumor growth, VTAs could be effective against all types of solid tumors. Our scientists are doing preliminary studies on VTAs. The VTA technology was acquired in April of 1997 through our acquisition of Peregrine Pharmaceuticals, Inc.

o VEAs use vasoactive compounds (molecules that cause tissues to become more permeable) linked to monoclonal antibodies, such as the TNT antibody, to increase the vasoactive permeability at the tumor site and are believed to act by increasing the concentration of killing agents at the core of the tumor. In pre-clinical studies, our scientists were able to increase the uptake of drugs or isotopes within a tumor by between 150% and 420% if a vasoactive agent was given several hours prior to the therapeutic treatment. The therapeutic drug can be a chemotherapy drug, a radioactive isotope or other cancer fighting agent. This enhancement of toxic drug dosing is achieved by altering the physiology and, in particular, the permeability of the blood vessels and capillaries that serve the tumor. As the tumor vessels become more permeable, the amount of therapeutic treatment reaching the tumor cells increases.

19

RESULTS OF OPERATIONS. The Company's net loss of $4,435,000, before preferred stock discount accretion and dividends, for the quarter ended January 31, 1999 represents an increase in net loss of $1,474,000 in comparison to the net loss of $2,961,000 for the prior year quarter ended January 31, 1998. This increase in the net loss for the quarter ended January 31, 1999 is due to an increase in total costs and expenses of $1,496,000 offset by an increase in interest and other income of $22,000. The Company's net loss of $11,245,000 for the nine months ended January 31, 1999 represents an increased loss of $2,584,000 over the nine months ended January 31, 1998. The increased loss for the nine months ended January 31, 1999 is due to a $2,403,000 increase in total costs and expenses combined with a $181,000 decrease in interest and other income.

The Company's total costs and expenses increased approximately $1,496,000 during the three months ended January 31, 1999 compared to the three months ended January 31, 1998. This increase in total costs and expenses resulted primarily an increase in non-cash charges of $1,010,000 from the sale and disposal of property, of which $1,171,000 was recorded in December 1998 in connection with the sale and subsequent leaseback of the Company's two facilities. In addition, during the three months ended January 31, 1999, research and development expenses increased $295,000, general and administrative expenses increased $209,000, and interest expense decreased $18,000, in comparison to the three months ended January 31, 1998. The Company's total costs and expenses increased $2,403,000 for the nine months ended January 31, 1999 compared to the same period in the prior year. This nine-month increase resulted from a $1,056,000 increase in research and development expenses, a $1,016,000 increase in non-cash charges from the sale and disposal of property, a $116,000 increase in general and administrative expenses and a $215,000 increase in interest expense.

The increase in research and development expenses of approximately $295,000 and $1,056,000 during the three and nine months ended January 31, 1999, respectively, primarily relates to increased clinical trial costs associated with the Phase II/III clinical trials of Oncolym(R), the Phase I and Phase II clinical trials of Tumor Necrosis Therapy ("TNT") and the start-up costs to commence Phase I/II clinical trials of TNT in Mexico. The increase in clinical trial costs resulted from increased patient fees, manufacturing and radiolabeling costs, and travel and consulting fees. In addition, internal research and development activities increased, including activities related to manufacturing and radiopharmaceutical scale-up and increased efforts to validate the manufacturing facility which caused a corresponding increase in related costs.

The increase in general and administrative expenses of $209,000 during the quarter ended January 31, 1999 compared to the quarter ended January 31, 1998 resulted primarily from severance expenses associated with the Company's former Chief Executive Officer and former Vice President of Operations and Administration and increased legal fees associated with the sale and subsequent leaseback of the Company's facilities. Such increases were partially offset by a decrease in consulting fees, a decrease in insurance related costs and a decrease in stock-based compensation expense. General and administrative expenses increased approximately $116,000 for the nine months ended January 31, 1999 compared to the same period in the prior year. Such increase was primarily due to the aforementioned increase in severance expenses and legal fees associated with the sale and subsequent leaseback of the Company's facilities which were partially offset by a non-recurring Class C preferred stock penalty of $276,000 recorded in the nine months ended January 31, 1998 combined with a decrease in consulting fees associated with Peregrine Pharmaceuticals, Inc., a decrease in recruiting fees, a decrease in insurance related expenses and a decrease in stock-based compensation expense.

20

The increase in non-cash charges from the sale and disposal of property of $1,010,000 and $1,016,000 for the three and nine month periods ended January 31, 1999, respectively, compared to the same period in the prior year is primarily due to the non-cash loss of $1,171,000 recorded on the sale and subsequent leaseback of the Company's facilities in December 1998 with an unrelated entity (buyer/landlord). The aggregate sales price of the two facilities was $6,100,000, which was comprised of $4,175,000 in cash and a note receivable for $1,925,000. The leaseback is a Triple Net Lease, whereas the Company is responsible for all expenses incurred in the maintenance of the building including property taxes and insurance. The initial lease term is twelve years with two five-year extension options. The initial base rent is $56,250 per month, with rent increases of 3.35% every two years.

The decrease in interest expense of $18,000 for the three months ended January 31, 1999 compared to the same period in the prior year is primarily due to a lower level of interest bearing debt outstanding during the quarter. The lower level of debt outstanding is due to the payoff of building debt in conjunction with the sale and subsequent leaseback of the Company's facilities in December 1998. The increase in interest expense of $215,000 for the nine months ended January 31, 1999 compared to the same period in the prior year is primarily due to interest incurred on construction loans owed to one of the Company's contractors related to enhancements to the Company's manufacturing facility. For the nine months ended January 31, 1999, approximately $115,000 was included in interest expense for the estimated fair value of 335,000 warrants granted to the above contractor for an extension of time to pay the outstanding construction loans. The construction loans were paid in full in August 1998.

The increase in interest and other income of $22,000 during the three months ended January 31, 1999 compared to the same period in the prior year is primarily due to initial funding received of $67,000 during the quarter ended January 31, 1999 from an unrestricted $200,000 grant from an unrelated entity to perform TNT clinical trials in Mexico. This unrestricted grant of $67,000 was offset by a decrease in interest income $45,000. The decrease in interest and other income for the nine months ended January 31, 1999 of $181,000 compared to the same period in the prior year, is primarily attributable to a decrease in interest income of $236,000 and a decrease in other income of $12,000 offset by an increase in grant funding of $67,000 to perform TNT clinical trials in Mexico. Interest income decreased during the three and nine month periods ended January 31, 1999 due to a lower level of cash funds available for investment. Interest income is not expected to be significant during the remainder of the fiscal year due to the expected level of future cash balances. The Company does not expect to generate product sales for at least the next year.

Management believes that research and development costs will increase as the Company continues to expand its clinical trial activities and increases production and radiolabeling capabilities for its Oncolym(R) and TNT antibodies.

LIQUIDITY AND CAPITAL RESOURCES. At January 31, 1999, we had $240,000 in cash and cash equivalents and a working capital deficit of $1,676,000. We experienced losses in fiscal 1998 and during the first nine months of fiscal 1999 and had an accumulated deficit of approximately $84,429,000 at January 31, 1999. On February 2, 1999, we exercised a put option and received gross proceeds of $2,250,000 in exchange for 2,869,564 shares of common stock pursuant to a Regulation D Common Stock Equity Line Subscription Agreement the (the "Equity Line Agreement"). In addition, on March 8, 1999, we entered into a licensing agreement with an unrelated entity for the licensing of Oncolym(R) in exchange for an up-front payment of $3,000,000. We believe we have sufficient cash on hand and available pursuant to the Equity Line Agreement (assuming only one future quarterly draw of $2,250,000 in May 1999) to meet our obligations on a timely basis through June 1999. We also believe that additional capital must be raised to support the Company's continued operations and other short-term cash needs.

Our ability to access funds under the Equity Line Agreement is subject to the satisfaction of certain conditions and the failure to satisfy these conditions may limit or preclude our ability to access such funds, which could adversely affect the our business, immediate liquidity, financial position and results of operations unless additional financing sources are available.

We have significant commitments to expend additional funds for radiolabeling contracts, license contracts, severance arrangements and consulting. We expect operating expenditures related to clinical trials to increase in the future as our clinical trial activity increases and scale-up for clinical trial production continues. We have experienced negative cash flows from operations since our inception and we expect the negative cash flow from operations to continue for the foreseeable future. We expect that the monthly negative cash flow will continue for at least the next year as a result of increased activities in connection with the Phase II/III clinical trials for Oncolym(R), the Phase I and Phase II clinical trials of TNT, the Phase I/II clinical trials of TNT in Mexico and the development costs associated with Vasopermeation Enhancement Agents ("VEAs") and Vascular Targeting Agents ("VTAs"). We believe that it will be necessary for us to raise additional capital to sustain research and development and provide for future clinical trials. Additional funds must be raised to continue our operations until we are able to generate sufficient additional revenue from the sale and/or licensing of our products. There can be no assurance that we will be successful in raising such funds on terms acceptable to us, or at all, or that sufficient capital will be raised to complete the research and development of our product candidates.

The increased clinical trial activities and the manufacturing and radiolabeling scale-up efforts have impacted the Company's losses and cash consumption rate ("burn rate"). We believe we can only reduce the burn rate significantly if we reduce programs substantially or delay clinical trials and continued development of the scale-up efforts. We believe that we will continue to experience losses and negative cash flow from operations for the foreseeable future as we increase activities associated with the Phase II/III clinical trials for Oncolym(R), the Phase I and Phase II clinical trials for TNT and the Phase I/II clinical trials of TNT in Mexico and activities associated with our research and development of our other technologies.

COMMITMENTS. At January 31, 1999, we had fixed commitments of approximately $1,540,000 related to radiolabeling contracts, severance arrangements, employment agreements and consulting agreements. In addition, we have additional significant obligations, most of which are contingent, for payments to licensors for its technologies and in connection with the acquisition of the Oncolym(R) rights previously owned by Alpha Therapeutic Corporation ("Alpha") and Biotechnology Development Ltd. ("BTD").

22

On March 8, 1999, the Company entered into a Termination Agreement with Biotechnology Development, Ltd. ("BTD"), pursuant to which the Company terminated all previous agreements with BTD and thereby reacquired the marketing rights to LYM products in Europe and certain other designated foreign countries, in exchange for (i) the issuance to BTD of a Secured Promissory Note in the principal face amount of $3,300,000 bearing simple interest at the rate of ten percent (10%) per annum, with interest payable monthly in advance and the full principal amount due and payable on March 1, 2001, (ii) the issuance of warrants to purchase up to 3,700,000 shares of Common Stock at an exercise price of $3.00 per share exercisable for a period of three (3) years, (iii) the issuance of warrants to purchase up to 1,000,000 shares of Common Stock at an exercise price of $5.00 per share exercisable for a period of five (5) years and (iv) the issuance of shares of Common Stock equal in value to $1,200,000, based on a value per share equal to ninety percent (90%) of the market price of the common stock. Pursuant to a related Security Agreement, the Company granted a security interest to BTD in and to all assets of the Company, excluding inventory, furniture, fixtures and equipment which are used in the commercialization of Oncolym(R) which are not located on the Company's Tustin, California premises or which serve as security to any other entity and further excluding any and all intangible property and intellectual property of the Company and any and all rights with respect thereto and any goodwill associated therewith.

Also on March 8, 1999, the Company entered into a License Agreement with Schering AG, Germany. Under the terms of the agreement, Schering AG, Germany was granted the exclusive, worldwide right to market and distribute LYM products in exchange for an initial payment of $3,000,000 which the Company received upon execution of the agreement, a further payment of $2,000,000 following the acceptance by the FDA for filing of the first drug approval application for Oncolym(R) in the United States, a further payment of $7,000,000 following regulatory approval of Oncolym(R) in the United States and two final payments of $2,500,000 each following regulatory approval of Oncolym(R) in any country in Europe and upon the first commercial sale of Oncolym(R) in any country in Europe. The Company will also receive a royalty equal to twelve percent (12%) of net sales of Oncolym(R) products (which is subject to reduction, on a country-by-country basis, to six percent (6%) if there is a generic form of the Oncolym(R) product being sold in such country), which may be reduced by one percentage point if the FDA does not consent to an extension of the existing Phase II trials of Oncolym(R) as a Phase III clinical trial by June 30, 1999. Pursuant to the terms of the agreement, the Company is required to pay for all pre-clinical expenses up to $500,000 incurred after March 8, 1999, and fifty percent (50%) of all such expenses incurred in excess of $500,000, with the other fifty percent of such expenses to be paid by Schering AG, Germany. The Company is also required to pay for twenty percent (20%) of the clinical development expenses and existing trial expenses associated with Oncolym(R), and Schering AG, Germany is required to pay for the other eighty percent (80%) of such expenses. Each party will pay for all of its internal costs relating to existing trials. Pursuant to the agreement, the Company and Schering AG, Germany have also agreed to a structure for proceeding with negotiations concerning the terms of a possible licensing of the Company's VTA technology in the near future. The continued effectiveness of the agreement with Schering AG, Germany is subject to certain other conditions and may be terminated by Schering AG, Germany if (i) there are issues of safety or patient tolerability, (ii) Schering AG, Germany determines in its reasonable scientific or business discretion prior to receiving regulatory approval that the Oncolym(R) product is not acceptable for reasons of efficacy or risk/benefit therapeutic ratio, (iii) the FDA does not permit the extension or conversion of the Phase II trials of Oncolym(R) as a Phase III clinical trial by June 30, 1999, (iv) Schering AG, Germany determines, using its reasonable judgment based on data from or the results of the first Phase III clinical trials of Oncolym(R) that such results do not support the submission of Oncolym(R) for regulatory approval, (v) the Company fails to deliver or it becomes reasonably clear that the Company will fail to deliver in time appropriate quantities of clinical supplies of antibody or Oncolym(R) product such that the clinical development of Oncolym(R) will be delayed by

23

three (3) months or more, (vi) if the Company has not concluded a definitive agreement providing for a radiolabeling site for the production of Oncolym(R) products by September 1, 1999, or (vii) at any time after receiving regulatory approval upon twelve months notice to the Company. However, if the agreement is terminated by Schering AG, Germany due to issues of safety or patient tolerability, or Schering AG, Germany determines in its reasonable scientific or business discretion prior to receiving regulatory approval that the Oncolym(R) product is not acceptable for reasons of efficacy or risk/benefit therapeutic ratio or determines, using its reasonable judgment based on data from or the results of the first Phase III clinical trials of Oncolym(R), that such results do not support the submission of Oncolym(R) for regulatory approval, Schering AG, Germany will remain obligated to pay for 80% of the non-cancellable third party costs in regard to clinical trials underway at the time of such termination, up to $1,500,000 (other than a termination after receiving regulatory approval). Schering AG, Germany may also terminate the agreement upon thirty days' written notice given at any time prior to receiving regulatory approval, but will remain obligated to pay for all of the costs of completing all then ongoing clinical trials for Oncolym(R), up to $3,000,000.

OTHER RISK FACTORS OF OUR COMPANY

OUR OPERATING RESULTS MAY FLUCTUATE SIGNIFICANTLY. Our actual operating results may fluctuate significantly in the future. Many factors may cause these fluctuations, including worldwide economic and political conditions and industry specific factors. If we are to remain competitive, we must develop and produce commercially viable products at competitive prices in a timely manner, and must maintain access to external financing sources until we can generate revenue from licensing transactions or sales of products. Our ability to obtain financing and to manage expenses and our cash depletion rate ("burn rate") is the key to the continued development of product candidates and the completion of ongoing clinical trials. Our burn rate will vary substantially from quarter to quarter as we fund non-recurring items associated with clinical trials, product development, antibody manufacturing and radiolabeling expansion and scale-up, patent legal fees and various consulting fees. We have limited experience with clinical trials and if we encounter unexpected difficulties with our operations or clinical trials, we may have to expend additional funds, which would increase our burn rate.

WE ARE IN THE EARLY STAGES OF PRODUCT DEVELOPMENT. Since our inception, we have been engaged in the development of drugs and related therapies for the treatment of people with cancer. Our product candidates are generally in the early stages of development, with only two product candidates currently in clinical trials. Revenues from product sales have been insignificant and throughout our history there have been minimal revenues from product royalties. If the initial results from any of the clinical trials are poor, those results will adversely effect our ability to raise additional capital, which will affect our ability to continue full-scale research and development for our antibody technologies. In addition, product candidates resulting from our research and development efforts, if any, are not expected to be available commercially for at least the next year. We cannot guarantee that our product development efforts, including clinical trials, will be successful, that required regulatory approvals for the indications being studied can be obtained, that our product candidates can be manufactured and radiolabeled at an acceptable cost and with appropriate quality or that any approved products can be successfully marketed.

24

WE WILL REQUIRE ADDITIONAL CAPITAL IN THE FUTURE. We have expended, and will continue to expend, substantial funds on the development of our product candidates and for clinical trials. As a result, we have experienced negative cash flows from operations since inception and expect the negative cash flow from operations to continue for the foreseeable future. We currently have commitments to expend additional funds for radiolabeling contracts, license contracts, severance arrangements, employment agreements, consulting agreements, and for the repurchase of Oncolym(R) marketing rights from Alpha Therapeutic Corporation and Biotechnology Development, Ltd. We expect operating expenditures related to clinical trials to increase in the future as clinical trial activity increases and scale-up for clinical trial production continues. As activities in connection with the Phase II/III clinical trials for Oncolym(R) and the Phase II clinical trials for TNT increase and the development costs associated with VEAs and VTAs increase, we expect that the monthly negative cash flow will continue. Without obtaining additional financing and/or negotiating additional licensing or collaboration agreements with other companies, we expect that current sources of financing available to us will be sufficient to fund our operations and to meet our obligations on a timely basis through June 1999. Our ability to access funds under our Regulation D Common Stock Equity Line Subscription Agreement with two institutional investors is subject to the satisfaction of certain conditions and the failure to satisfy these conditions may limit or preclude our ability to access such funds, which could negatively affect our financial position unless additional financing sources are available.

We will require additional funds to sustain our research and development efforts, provide for future clinical trials, expand our manufacturing and radiolabeling capabilities, and continue our operations until we able to generate sufficient revenue from the sale and/or licensing of our products. We will need to obtain additional funding through one or more methods including obtaining additional equity or debt financing and/or negotiating additional licensing or collaboration agreement with another company. We cannot be certain whether we can obtain the required additional funding on terms satisfactory to us, if at all. If we do raise additional funds through the issuance of equity or convertible debt securities, your stock ownership will be diluted. Further, these new securities may have rights, preferences or privileges senior to yours. If we are unable to raise additional funds when necessary, we may have to reduce or discontinue development or clinical testing of some or all of our product candidates or enter into financing arrangements on terms which we would not otherwise accept.

WE HAVE HAD SIGNIFICANT LOSSES AND ANTICIPATE FUTURE LOSSES. We have experienced significant losses since inception. As of January 31, 1999, our accumulated deficit was approximately $84,429,000. We expect to incur significant additional operating losses in the future and expect cumulative losses to increase substantially due to expanded research and development efforts, preclinical studies and clinical trials, and scale-up of manufacturing and radiolabeling capabilities. We expect losses to fluctuate substantially from quarter to quarter. All of our products are currently in development, preclinical studies or clinical trials, and no significant revenues have been generated from product sales. To achieve and sustain profitable operations, we must successfully develop and obtain regulatory approval for our products, either alone or with others, and must also manufacture, introduce, market and sell our products. The time frame necessary to achieve market success for our products is long and uncertain. We do not expect to generate significant product revenues for the next year. There can be no guarantee that we will ever generate product revenues sufficient to become profitable or to sustain profitability.

25

THE VIABILITY OF OUR TECHNOLOGY AND PRODUCTS IS UNCERTAIN. Our future success is significantly dependent on our ability to develop and test workable products for which we will seek FDA approval to market to certain defined patient groups. There is a significant risk as to the performance and commercial success of our technology and products. The products we are currently developing will require significant additional laboratory and clinical testing and investment over the foreseeable future. Although we are optimistic that we will be able to complete development of one or more products, there are many risk and uncertainties inherent in developing pharmaceutical products. For example:

o Our research and development activities may not be successful;
o Our proposed products may not prove to be effective in clinical trials;
o Patient enrollment in the clinical trials may be delayed or prolonged significantly, thus delaying the trials;
o Our product candidates may cause harmful side effects during clinical trials;
o Our product candidates may take longer than anticipated to progress through clinical trials;
o Our product candidates may prove impracticable to manufacture in commercial quantities at a reasonable cost and/or with acceptable quality;
o Our competitors may produce products which are superior to our products;
o We may not be able to obtain all necessary governmental clearances and approvals to market our products;
o Our product candidates may not prove to be commercially viable or successfully marketed; and
o We may encounter unanticipated problems, including development, manufacturing, distribution, financing and marketing difficulties.

Any of these factors could negatively affect our financial position and results of operations.

WE HAVE LIMITED DATA TO DATE WITH RESPECT TO OUR PRODUCT CANDIDATES. The results of initial preclinical and clinical testing of the products we are currently developing are not necessarily indicative of results that will be obtained from subsequent or more extensive preclinical studies and clinical testing. The clinical data gathered to date with respect to Oncolym(R) are primarily from a Phase II dose escalation trial, which was designed to develop and refine the therapeutic protocol to determine the maximum tolerated dose of total body radiation and to assess the safety and efficacy profile of a treatment with a radiolabeled antibody. Further, the data from this Phase II dose escalation trial was compiled from testing conducted at a single site and with a relatively small number of patients. We will need to do substantial additional development and clinical testing prior to seeking any regulatory approval for commercialization of Oncolym(R). There can be no guarantee that clinical trials of Oncolym(R), TNT or other product candidates under development will demonstrate the safety and efficacy of such products to the extent necessary to obtain regulatory approvals for the indications being studied, or at all. Companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in advanced clinical trials, even after obtaining promising results in earlier trials. The failure to adequately demonstrate the safety and efficacy of Oncolym(R), TNT or any other therapeutic product under development could delay or prevent regulatory approval of the product, which would negatively affect our financial position and results of operations.

26

THERE ARE MANY RISKS ASSOCIATED WITH OBTAINING REGULATORY APPROVALS. Testing, manufacturing, radiolabeling, advertising, promotion, export and marketing, among other things, of our proposed products are subject to extensive regulation by governmental authorities in the United States and other countries. In the United States, pharmaceutical products are regulated by the FDA under the Federal Food, Drug, and Cosmetic Act and other laws, including, in the case of biologics, the Public Health Service Act. We presently believe that our products will be regulated by the FDA as biologics. Manufacturers of biologics may also be subject to state regulation.

There are numerous steps required before a biologic may be approved for marketing in the United States, generally including:

o preclinical laboratory tests and animal tests;
o submission to the FDA of an Investigational New Drug ("IND") application for human clinical testing, which must become effective before human clinical trials may commence;
o adequate and well-controlled human clinical trials to establish the safety and efficacy of the product;
o submission to the FDA of a Product License Application ("PLA") or a Biologics License Application ("BLA");
o submission to the FDA of an Establishment License Application ("ELA");
o FDA review of the ELA and the PLA or BLA; and
o satisfactory completion of an FDA inspection of the manufacturing facility or facilities at which the product is made to assess compliance with Current Good Manufacturing Practices ("CGMP").

The testing and approval process requires substantial time, effort and financial resources and we cannot guarantee that any approval will be granted on a timely basis, if at all. We cannot guarantee that Phase I, Phase II or Phase III testing will be completed successfully within any specific time period, if at all, with respect to any of our product candidates. Furthermore, the FDA may suspend clinical trials at any time on various grounds, including a finding that the subjects or patients are being exposed to an unacceptable health risk.

The results of preclinical and clinical studies, together with detailed information on the manufacture and composition of a product candidate, are submitted to the FDA as a PLA or BLA requesting approval to market the product candidate. Before approving a PLA or BLA, the FDA will inspect the facilities at which the product is manufactured, and will not approve the marketing of the product candidate unless CGMP compliance is satisfactory. The FDA may deny a PLA or BLA if applicable regulatory criteria are not satisfied, require additional testing or information and/or require post-marketing testing and surveillance to monitor the safety or efficacy of a product. There can be no assurance that approval of any PLA or BLA we submit will be granted by the FDA on a timely basis or at all. Also, if regulatory approval of a product is granted, such approval may entail limitations on the indicated uses for which it may be marketed.

Both before and after FDA approval is obtained, violations of regulatory requirements, including the preclinical and clinical testing process, or the PLA or BLA review process may result in various adverse consequences, including the FDA's delay in approving or refusing to approve a product, withdrawal of an approved product from the market and/or the imposition of criminal penalties against the manufacturer and/or license holder. For example, license holders are required to report certain adverse reactions to the FDA, and to comply with certain requirements concerning advertising and promotional labeling for their products. Also, quality control and manufacturing procedures must continue to conform to CGMP regulations after approval, and the FDA periodically inspects manufacturing facilities to assess compliance with CGMP. Accordingly, manufacturers must continue to expend time, monies and effort in the area of production and quality control to maintain CGMP compliance. In addition, discovery of problems may result in restrictions on a product and/or its manufacturer, including withdrawal of the product from the market. Also, new government requirements may be established that could delay or prevent regulatory approval of our product candidates.

27

We will also be subject to a variety of foreign regulations governing clinical trials and sales of our products. Whether or not FDA approval has been obtained, approval of a product candidate by the comparable regulatory authorities of foreign countries must be obtained prior to the commencement of marketing of the product in those countries. The approval process varies from country to country and the time may be longer or shorter than that required for FDA approval. At least initially, we intend, to the extent possible, to rely on licensees to obtain regulatory approval for marketing our products in foreign countries.

THERE ARE MANY RISKS ASSOCIATED WITH THE COMMERCIAL PRODUCTION OF OUR PRODUCTS. In order to conduct clinical trials on a timely basis, obtain regulatory approval and be commercially successful, we must scale-up our manufacturing and radiolabeling processes so that those product candidates can be manufactured and radiolabeled in commercial quantities. To date, we have expended significant funds for the scale-up of our antibody manufacturing capabilities for clinical trial requirements for our Oncolym(R) and TNT product candidates and for refinement of the radiolabeling processes. We intend to use existing antibody manufacturing capacity to meet the clinical trial requirements for our Oncolym(R) and TNT product candidates and to support the initial commercialization of Oncolym(R). In order to provide additional capacity, we must successfully negotiate an agreement with contract antibody manufacturers to have these products produced, the cost of which is estimated to be approximately one to three million dollars in start-up costs and additional production costs on a "per run basis". We believe we can successfully negotiate an agreement with one or more contract radiolabeling companies to provide radiolabeling services to meet commercial demands. Such a contract would, however, require a substantial investment (estimated at five to nine million dollars over the next two years) for equipment and related production area enhancements required by these vendors, and for vendor services associated with technology transfer assistance, scale-up and production start-up, and for regulatory assistance. We anticipate that production of our products in commercial quantities will create technical and financial challenges. We have limited manufacturing experience, and cannot make any guarantee as to our ability to scale-up our manufacturing operations, the suitability of our present facility for clinical trial production or commercial production, our ability to make a successful transition to commercial production and radiolabeling or our ability to reach an acceptable agreement with one or more contract manufacturers to produce and radiolabel Oncolym(R), TNT, or any of our other product candidates, in clinical or commercial quantities. Our failure to scale-up manufacturing and radiolabeling for clinical trial or commercial production or to obtain contract manufacturers, could negatively affect our financial position and results of operations.

28

THERE ARE SUBSTANTIAL SHARES ELIGIBLE FOR FUTURE SALE; THE SALE OF SUCH SHARES MAY DEPRESS OUR STOCK PRICE. As of February 28, 1999, we had 70,898,581 shares of Common Stock outstanding. We will issue additional shares of Common Stock and/or warrants to purchase shares of Common Stock under the following agreements:

o 5% Adjustable Convertible Class C Preferred Stock ("Class C Stock");
o Regulation D Common Stock Equity Line Subscription Agreement ("Equity Line Agreement") and a related Placement Agent Agreement;
o Biotechnology Development, Ltd. Termination Agreement; and
o other Option and Warrant Agreements.

CLASS C STOCK. Of the 70,898,581 shares of Common Stock outstanding as of February 28, 1999, from September 26, 1997 (the date the Class C Stock became convertible into Common Stock) through February 28, 1999, we issued 30,865,164 shares of Common Stock in conjunction with the conversion of the Class C Stock (including shares of Class C Stock issued as dividends shares and penalty shares) and the exercise of warrants to purchase shares of Common Stock (the "Class C Warrants") for gross proceeds of approximately $15,641,000. The Class C Warrants were issued to holders of Class C Stock in conjunction with the conversion of the Class C Stock pursuant to the terms of the Company's agreement with the holders of the Class C Stock. From September 26, 1997, the date on which the Class C Stock was first convertible, through March 1998, the price of the Common Stock steadily declined while the average trading volume increased significantly. As of February 28, 1999, there were 121 shares of Class C Stock outstanding and Class C Warrants outstanding to purchase up to 35,244 shares of Common Stock. If the 121 shares of Class C Stock outstanding as of February 28, 1999 were converted, we would be required to issue approximately 203,000 shares of Common Stock (based on a conversion price of $0.5958 per share of Common Stock) and Class C Warrants to purchase up to an aggregate of approximately 51,000 shares of Common Stock at an exercise price of $0.6554 per share.

EQUITY LINE AGREEMENT. As of February 28, 1999, we have issued an aggregate of 5,789,506 shares of Common Stock and warrants to purchase up to an additional 566,953 shares of Common Stock at an average exercise price of $1.23 per share under the Equity Line Agreement and related Placement Agent Agreement for gross proceeds of $5.75 million. Pursuant to the Equity Line Agreement, and assuming a 10-day low closing bid price of $1.00 per share (which allows us to sell the maximum number of shares of Common Stock), we may, at our option, sell to the institutional investors up to an additional 17,812,500 shares of Common Stock and warrants to purchase up to an additional 1,781,250 shares of Common Stock for gross proceeds of $14,250,000. In addition, we may be obligated to issue for no additional consideration up to 1,876,704 shares of Common Stock and warrants to purchase up to 178,125 shares of Common Stock pursuant to the Placement Agent Agreement. The shares of Common Stock will be issued and sold to the institutional investors at a discount to the 10-day low closing bid price of the Common Stock prior to the sale equal to the greater of twenty cents ($0.20) per share or a 17.5% discount to the 10-day low closing bid price of the Common Stock. In addition, we may be obligated to issue to the institutional investors an aggregate of up to 954,545 shares of Common Stock on April 15, 1999 and July 15, 1999 upon adjustment of the purchase price of the shares of Common Stock sold to the institutional investors. We will not receive any proceeds from the exercise of warrants under the Equity Line Agreement or the Placement Agent Agreement to purchase shares of Common Stock, which may only be exercised pursuant to a cashless exercise.

29

BIOTECHNOLOGY DEVELOPMENT LTD. TERMINATION AGREEMENT. On March 8, 1999, the Company entered into a Termination Agreement with Biotechnology Development, Ltd. ("BTD"), pursuant to which the Company terminated all previous agreements with BTD and thereby reacquired the marketing rights to LYM products in Europe and certain other designated foreign countries, in exchange for (i) the issuance to BTD of a Secured Promissory Note in the principal face amount of $3,300,000 bearing simple interest at the rate of ten percent (10%) per annum, with interest payable monthly in advance and the full principal amount due and payable on March 1, 2001, (ii) the issuance of warrants to purchase up to 3,700,000 shares of Common Stock at an exercise price of $3.00 per share exercisable for a period of three (3) years (iii) the issuance of warrants to purchase up to 1,000,000 shares of Common Stock at an exercise price of $5.00 per share exercisable for a period of five (5) years and (iv) the issuance of shares of Common Stock equal in value to $1,200,000, based on a value per share equal to ninety percent (90%) of the market price of the Common Stock.

OTHER OPTION AND WARRANT AGREEMENTS. In addition to the Class C Warrants, the warrants issued and to be issued under the Equity Line Agreement and the Placement Agent Agreement and the warrants issued to BTD under the Termination Agreement, at February 28, 1999, there were outstanding warrants and options to employees, directors, consultants and other parties to issue approximately 8,453,000 shares of Common Stock at an average exercise price of $1.17 per share.

The sale and issuance of shares of Common Stock pursuant to the Equity Line Agreement and related Placement Agent Agreement and pursuant to the Termination Agreement may cause the market price of the Common Stock to fall and might also make it more difficult for us to sell equity or equity-related securities in the future, whether pursuant to the Equity Line Agreement or otherwise. The issuance of shares of Common Stock upon conversion of the remaining Class C Stock and upon exercise of the Class C Warrants, the warrants issued to BTD and the warrants issued and to be issued under the Equity Line Agreement, and such other outstanding warrants and options, as well as subsequent sales of shares of Common Stock in the open market, could also cause the market price of the Common Stock to fall and impair our ability to raise additional capital.

OUR STOCK PRICE AND TRADING VOLUME HAVE BEEN HIGHLY VOLATILE. The market price of the Common Stock, and the market prices of securities of companies in the biotechnology industry generally, have been highly volatile and is likely to continue to be highly volatile. Also, the trading volume in the Common Stock has been highly volatile, ranging from as few as 89,000 shares per day to as many as 19 million shares per day over the past year, and is likely to continue to be highly volatile. The market price of the Common Stock may be significantly impacted by, for example:

o Announcements of technological innovations or new commercial products by us or our competitors;
o Developments or disputes concerning patent or proprietary rights;
o Publicity regarding actual or potential medical results relating to products under development by us or our competitors;
o Regulatory developments in both the United States and foreign countries;
o Public concern as to the safety of biotechnology products;
o Economic and other external factors; and
o Period-to-period fluctuations in financial results.

30

THERE ARE RISKS RELATED TO SECURITIES LISTED ON THE NASDAQ SMALLCAP MARKET AND LOW-PRICED SECURITIES. The Common Stock is presently traded on The Nasdaq SmallCap Market. To maintain inclusion on The Nasdaq SmallCap Market, the Common Stock must continue to be registered under Section 12(g) of the Exchange Act, and we must continue to have either net tangible assets of at least $2,000,000, market capitalization of at least $35,000,000, or net income (in either our latest fiscal year or in two of our last three fiscal years) of at least $500,000. In addition, we must meet other requirements, including, but not limited to, having a public float of at least 500,000 shares and $1,000,000, a minimum closing bid price of $1.00 per share of Common Stock (without falling below this minimum bid price for a period of 30 consecutive business days), at least two market makers and at least 300 stockholders, each holding at least 100 shares of Common Stock. For the period of January 29, 1998 through May 4, 1998, we failed to maintain a $1.00 minimum closing bid price. From May 5, 1998, through September 2, 1998, we met this requirement. However, at various times since September 2, 1998, we have failed to maintain a $1.00 minimum closing bid price and expect the closing bid price of the Common Stock to fall below the $1.00 minimum bid requirement from time to time in the future. If we fail to meet the minimum closing bid price of $1.00 for a period of 30 consecutive business days, we will be notified by The Nasdaq Stock Market and will then have a period of 90 calendar days from such notification to achieve compliance with the applicable standard by meeting the minimum closing bid price requirement for at least 10 consecutive business days during such 90 day period. We cannot guarantee that we will be able to maintain these requirements in the future. If we fail to meet The Nasdaq SmallCap Market listing requirements, the market value of the Common Stock could fall and holders of Common Stock would likely find it more difficult to dispose of and to obtain accurate quotations as to the market value of the Common Stock. In addition, if the minimum closing bid price of the Common Stock is not at least $1.00 per share for 10 consecutive business days before we make a call for proceeds under our Regulation D Common Stock Equity Line Subscription Agreement with two institutional investors or if the Common Stock ceases to be included on The Nasdaq SmallCap Market, we would have limited or no access to funds under the Regulation D Common Stock Equity Line Subscription Agreement.

If the Common Stock ceases to be included on The Nasdaq SmallCap Market, the Common Stock could become subject to rules adopted by the SEC regulating broker-dealer practices in connection with transactions in "penny stocks." Penny stocks generally are equity securities with a price per share of less than $5.00 (other than securities registered on certain national securities exchanges or quoted on The Nasdaq Stock Market, provided that current price and volume information with respect to transactions in these securities is provided). The penny stock rules require a broker-dealer, prior to a transaction in a penny stock not otherwise exempt from the rules, to deliver a standardized risk disclosure document in a form prepared by the SEC which provides information about penny stocks and the nature and level of risks in the penny stock market. The broker-dealer also must provide the customer with current bid and offer quotations for the penny stock, the compensation of the broker-dealer and its sales person in the transaction and monthly account statements showing the market value of each penny stock held in the customer's account. The bid and offer quotations, and the broker-dealer and salesperson compensation information, must be given to the customer orally or in writing prior to effecting the transaction and must be given to the customer in writing before or with the customer's confirmation. In addition, the penny stock rules require that prior to a transaction in a penny stock not otherwise exempt from these rules, the broker-dealer must make a special written determination that the penny stock is a suitable investment for the purchaser and receive the purchaser's written agreement to the transaction. These disclosure requirements may have the effect of reducing the level of trading activity in the secondary market for a stock that becomes subject to these penny stock rules. If the Common Stock becomes subject to the penny stock rules, investors may be unable to readily sell their shares of Common Stock.

OUR INDUSTRY IS HIGHLY COMPETITIVE. The biotechnology industry is intensely competitive. It is also subject to rapid change and sensitive to new product introductions or enhancements. We expect to continue to experience significant and increasing levels of competition in the future. Virtually all of our existing competitors have greater financial resources, larger technical staffs, and larger research budgets than we have and greater experience in developing products and running clinical trials. Two of our competitors, Idec Pharmaceuticals Corporation and Coulter Pharmaceuticals, Inc., each has a lymphoma antibody that may compete with our Oncolym(R) product. Idec Pharmaceuticals Corporation is currently marketing its lymphoma product for low grade non-Hodgkins Lymphoma and we believe that Coulter Pharmaceuticals, Inc. will be marketing its respective lymphoma product prior to the time our Oncolym(R) product will be submitted to the FDA for marketing approval. Coulter Pharmaceuticals, Inc. has also announced that it intends to seek to conduct clinical trials of its antibody treatment for intermediate and/or high grade non-Hodgkins lymphomas. There are several companies in preclinical studies with angiogenesis technologies which may compete with our VTA technology. In addition, there may be other companies which are currently developing competitive technologies and products or which may in the future develop technologies and products which are comparable or superior to our technologies and products. Some or all of these companies may also have greater financial and technical resources than we have. Accordingly, we cannot assure you that we will be able to compete successfully or that competition will not negatively affect our financial position or results of operations. In addition, we cannot assure you that our existing and future competitors will not develop products which compete with our other product candidates.

THERE ARE MANY RISKS AND UNCERTAINTIES ASSOCIATED WITH CLINICAL TRIALS. We have limited experience in conducting clinical trials. The rate of completion of our clinical trials will depend on, among other factors, the rate of patient enrollment. Patient enrollment is a function of many factors, including the nature of clinical trial protocols, the existence of competing protocols, the size of the patient population, the proximity of patients to clinical sites and the eligibility criteria for the study. Delays in patient enrollment will result in increased costs and delays, which could negatively affect our financial position and results of operations. We cannot assure you that patients enrolled in our clinical trials will respond to our product candidates. In fact, setbacks are to be expected in conducting human clinical trials. In addition, our failure to comply with FDA regulations applicable to this testing could result in substantial delays, suspension or cancellation of the testing, or refusal by the FDA to accept the results of the testing. The FDA may suspend clinical trials at any time if it concludes that the subjects or patients participating in such trials are being exposed to unacceptable health risks. We also cannot assure you that human clinical testing will show any current or future product candidates to be safe or effective or that data derived from the testing will be suitable for submission to the FDA. Any suspension or delay of any of the clinical trials could negatively affect our financial position and results of operations.

MARKET ACCEPTANCE OF OUR PRODUCTS IS UNCERTAIN. Even if our products are approved for marketing by the FDA and other regulatory authorities, we cannot guarantee that our products will be commercially successful. If our products currently in clinical trials, Oncolym(R) and TNT, are approved, they would represent a departure from more commonly used methods for cancer treatment. Accordingly, Oncolym(R) and TNT may experience under-utilization by oncologists and hematologists who are unfamiliar with the application of Oncolym(R) and TNT in the treatment of cancer. As with any new drug, doctors may be inclined to continue to treat patients with conventional therapies, in most cases chemotherapy, rather than new alternative therapies. We or our marketing partner will be required to implement an aggressive education and promotion plan with doctors in order to gain market recognition, understanding and acceptance of our products. Market acceptance also could be affected by the availability of third party reimbursement. Failure of Oncolym(R) or TNT to achieve market acceptance would negatively affect our financial position and results of operations.

32

WE ARE DEPENDENT ON A LIMITED NUMBER OF PROVIDERS OF RADIOLABELING SERVICES. We currently procure, and intend in the future to procure, our radiolabeling services pursuant to negotiated contracts with two domestic entities and one European entity. We cannot guarantee that these suppliers will be able to qualify their facilities or label and supply antibody in a timely manner, if at all, or that governmental clearances will be provided in a timely manner, if at all, or that clinical trials will not be delayed or disrupted. Prior to commercial distribution, we will be required to identify and contract with a commercial radiolabeling company for commercial services. We are presently in discussions with a few companies to provide commercial radiolabeling services. A commercial radiolabeling service agreement will require us to make a substantial investment of funds. We currently rely on, and expect in the future to rely on, our current suppliers for all or a significant portion of our requirements for the Oncolym(R) and TNT antibody products. Radiolabeled antibody cannot be stockpiled against future shortages due to the eight-day half-life of the I131 radioisotope. Accordingly, any change in our existing or future contractual relationships with, or an interruption in supply from, any third-party supplier could negatively impact our ability to complete ongoing clinical trials and to market the Oncolym(R) and TNT antibodies, if approved, which would negatively affect our financial position and results of operations.

THERE ARE RISKS ASSOCIATED WITH THE MANUFACTURING AND USE OF HAZARDOUS AND RADIOACTIVE MATERIALS. The manufacturing and use of Oncolym(R) and TNT require the handling and disposal of the radioactive isotope I131. We currently rely on, and intend in the future to rely on, our current contract manufacturers to radiolabel antibodies with I131 and to comply with various local, state and or national and international regulations regarding the handling and use of radioactive materials. Violation of these local, state, national or international regulations by these radiolabeling companies or a clinical trial site could significantly delay completion of the trials. Violations of safety regulations could occur with these manufacturers, so there is also a risk of accidental contamination or injury. Accordingly, we could be held liable for any damages that result from an accident, contamination or injury caused by the handling and disposal of these materials, as well as for unexpected remedial costs and penalties that may result from any violation of applicable regulations, which could negatively affect our financial position and results of operations. In addition, we may incur substantial costs to comply with environmental regulations. In the event of any noncompliance or accident, the supply of Oncolym(R) and TNT for use in clinical trials or commercially could be interrupted, which could negatively impact our financial position and results of operations.

WE ARE DEPENDENT ON THIRD PARTIES FOR COMMERCIALIZATION. We intend to sell our products in the United States and internationally in collaboration with one or more marketing partners. At the present time, we do not have a sales force to market Oncolym(R) or TNT, or any other product. If and when the FDA approves Oncolym(R) or TNT, the marketing of Oncolym(R) and TNT will be contingent upon our ability to either license or enter into a marketing agreement with a large company or our ability to recruit, develop, train and deploy our own sales force. We do not presently possess the resources or experience necessary to market Oncolym(R), TNT or any other product candidates. Other than an agreement with Schering AG, Germany with respect to the marketing of Oncolym(R), we presently have no agreements for the licensing or marketing of our product candidates, and we cannot assure you that we will be able to enter into any such agreements in a timely manner or on commercially favorable terms, if at all. Development of an effective sales force requires significant financial resources, time and expertise. We cannot assure you that we will be able to obtain the financing necessary or to establish such a sales force in a timely or cost effective manner, if at all, or that such a sales force will be capable of generating demand for our product candidates.

33

OUR SUCCESS IS DEPENDENT ON OBTAINING AND MAINTAINING PATENTS AND LICENSES TO PATENTS. Our success depends, in large part, on our ability to obtain or maintain a proprietary position in our products through patents, trade secrets and orphan drug designations. We have been granted several United States patents and have submitted several United States patent applications and numerous corresponding foreign patent applications, and have also obtained licenses to patents or patent applications owned by other entities. However, we cannot assure you that any of these patent applications will be granted or that our patent licensors will not terminate any of our patent licenses. We also cannot guarantee that any issued patents will provide competitive advantages for our products or that any issued patents will not be successfully challenged or circumvented by our competitors. The patent position worldwide of biotechnology companies in relation to proprietary products is highly uncertain and involves complex legal and factual questions. Moreover, any patents we or our licensors are granted may be infringed by others or may not be enforceable against others. We cannot assure you that any of our or our licensors' patents would be held valid or enforceable by a court of competent jurisdiction. Although we believe that our patents and our licensors' patents do not infringe on any third party's patents, we cannot be certain that we will not become involved in litigation involving patents or other proprietary rights. Patent and proprietary rights litigation entails substantial legal and other costs, and we do not know if we will have the necessary financial resources to defend or prosecute our rights in connection with any litigation. Responding to, defending or bringing claims related to patents and other intellectual property rights may require our management to redirect our human and monetary resources to address these claims and may take several years to resolve.

A substantial number of patents have already been issued to other biotechnology and biopharmaceutical companies. Particularly in the monoclonal antibody and angiogenesis fields, our competitors may have filed applications for or have been issued patents and may obtain additional patents and proprietary rights relating to similar or competitive products or processes. To date, we are not aware of any consistent policy regarding the breadth of claims allowed in biopharmaceutical patents. We cannot assure you that there are no existing patents in the United States or in foreign countries or that no future patents will be issued that would have a negative impact on our ability to market any of our existing or future products or product candidates. We expect that commercializing monoclonal antibody-based products may require licensing and/or cross-licensing of patents with other companies in this field. We cannot guarantee that any licenses which might be required for our processes or products, will be available, if at all, on commercially acceptable terms. If we are required to acquire rights to valid and enforceable patents but cannot do so at a reasonable cost, our ability to manufacture our products would be negatively impacted. Moreover, the likelihood of successfully contesting the scope or validity of such patents is uncertain and the costs associated therewith may be significant.

We also rely on trade secrets and proprietary know-how, which we attempt to protect, in part, by confidentiality agreements with our employees and consultants. We cannot be certain that these agreements will not be breached, that we will have adequate remedies for any breach, or that our trade secrets will not otherwise become known or be independently developed by our competitors.

34

WE ARE EXPOSED TO PRODUCT LIABILITY CLAIMS. The manufacture and sale of human therapeutic products involve an inherent risk of product liability claims. We maintain only limited product liability insurance. However, we cannot assure you that we will be able to maintain existing insurance or obtain additional product liability insurance on acceptable terms or with adequate coverage against potential liabilities. Product liability insurance is expensive, difficult to obtain and may not be available in the future on acceptable terms, if at all. Our inability to obtain sufficient insurance coverage on reasonable terms or to otherwise protect against potential product liability claims in excess of our insurance coverage, if any, or a product recall could negatively impact our financial position and results of operations.

THERE ARE RISKS ASSOCIATED WITH HEALTH CARE REFORM AND THIRD-PARTY REIMBURSEMENT. Political, economic and regulatory influences are subjecting the health care industry in the United States to fundamental change. Recent initiatives to reduce the federal deficit and to reform health care delivery are increasing cost-containment efforts. We anticipate that Congress, state legislatures and the private sector will continue to review and assess alternative benefits, controls on health care spending through limitations on the growth of private health insurance premiums and Medicare and Medicaid spending, the creation of large insurance purchasing groups, price controls on pharmaceuticals and other fundamental changes to the health care delivery system. Any such changes could negatively impact our ultimate profitability. Legislative debate is expected to continue in the future, and market forces are expected to drive reductions of health care costs. We cannot predict what impact the adoption of any federal or state health care reform measures or future private sector reforms may have on our business.

Our ability to successfully commercialize our product candidates will depend in part on the extent to which appropriate reimbursement codes and authorized cost reimbursement levels of such products and related treatment are obtained from governmental authorities, private health insurers and other organizations, such as health maintenance organizations ("HMOs"). The Health Care Financing Administration ("HCFA"), the agency responsible for administering the Medicare program, sets requirements for coverage and reimbursement under the program, pursuant to the Medicare law. In addition, each state Medicaid program has individual requirements that affect coverage and reimbursement decisions under state Medicaid programs for certain health care providers and recipients. Private insurance companies and state Medicaid programs are influenced, however, by the HCFA requirements.

There can be no assurance that any of our product candidates, once available, will be included within the then current Medicare coverage determination. In the absence of national Medicare coverage determination, local contractors that administer the Medicare program, within certain guidelines, can make their own coverage decisions. Favorable coverage determinations are made in those situations where a procedure falls within allowable Medicare benefits and a review concludes that the service is safe, effective and not experimental. Under HCFA coverage requirements, FDA approval for marketing will not necessarily lead to a favorable coverage decision. A determination will still need to be made as to whether the product is reasonable and necessary for the purpose used. In addition, HCFA has proposed adopting regulations that would add cost-effectiveness as a criterion in determining Medicare coverage. Changes in HCFA's coverage policy, including adoption of a cost-effective criterion, could negatively impact our financial position and results of operations.

35

Third-party payers are increasingly challenging the prices charged for medical products and services. Also, the trend toward managed health care in the United States and the concurrent growth of organizations such as HMOs, which could control or significantly influence the purchase of health care services and products, as well as legislative proposals to reform health care or reduce government insurance programs, may all result in lower prices for our product candidates than we currently expect. The cost containment measures that health care payers and providers are instituting and the effect of any health care reform could negatively affect our ability to operate profitably.

WE ARE DEPENDENT ON KEY PERSONNEL. Our success is dependent, in part, upon a limited number of key executive officers and technical personnel remaining employed with us, including Larry O. Bymaster, our President and Chief Executive Officer, Steven C. Burke, our Chief Financial Officer, Dr. John Bonfiglio, our Vice President of Business Development, and Dr. Jamie Oliver, our Vice President of Clinical and Regulatory Affairs. We also believe that our future success will depend largely upon our ability to attract and retain highly-skilled research and development and technical personnel. We face intense competition in our recruiting activities, including larger companies. We do not know if we will be successful in attracting or retaining skilled personnel. Further, the loss of certain key employees or our inability to attract and retain other qualified employees could negatively affect our financial position and results of operation.

YEAR 2000 ISSUE RISKS MAY RESULT IN A MATERIAL ADVERSE EFFECT ON OUR BUSINESS. We are aware of the issues associated with the programming code in existing computer systems as the year 2000 approaches. The year 2000 problem is pervasive and complex. Virtually every computer operation will be affected in some way by the rollover of the two digit year value to "00". The issue is whether computer systems will properly recognize date-sensitive information when the year changes to 2000. Systems that do not properly recognize such information could generate erroneous data or cause a system to fail. We have identified substantially all of our major hardware and software platforms in use and are continually modifying and upgrading our software and information technology and other systems. We have modified our current financial software to be year 2000 compliant and expect all of our internal computer systems to be year 2000 compliant by April 30, 1999 through the use of internal and external resources. Although we do not presently believe that, with upgrades of existing software and/or conversion to new software, the year 2000 problem will pose significant operational problems for our internal computer systems or have a negative affect on our financial position or results of operations, we cannot assure you that any year 2000 compliance problems of our suppliers will not negatively affect our financial position or results of operation. Because uncertainty exists concerning the potential costs and effects associated with any year 2000 compliance, we intend to continue to make efforts to ensure that third parties with whom we have relationships are year 2000 compliant. We have not incurred significant costs to date associated with year 2000 compliance and presently believe estimated future costs will not be material. However, actual results could differ materially from our expectations due to unanticipated technological difficulties or project delays. If we or any third parties upon which we rely are unable to address the year 2000 issue in a timely manner, it could have an adverse impact on our financial position and results of operations. In order to assure that this does not occur, we are in the process of developing a contingency plan intend to devote all resources required to attempt to resolve any significant year 2000 issues in a timely manner.

THERE ARE RISKS ASSOCIATED WITH EARTHQUAKES. Our corporate and research facilities, where the majority of our research and development activities are conducted, are located near major earthquake faults which have experienced earthquakes in the past. Although we carry limited earthquake insurance, in the event of a major earthquake or other disaster affecting our facilities, our operations, financial position and results of operations will be negatively affected.

67

circumstances which would change or render incorrect, in whole or in part, any representation or warranty made by Seller under this Agreement, whether as of the date given or at any time thereafter to and including the Closing Date and whether or not such representation was based on Seller's knowledge and/or belief as of a certain date, Seller will give prompt written notice of such change, fact or circumstance to Purchaser.

In such defense or settlement of any claims, Purchaser shall provide Seller with originals or copies of all relevant documents and provide its utmost cooperation with and assistance to Seller, at no expense to Purchaser. Notwithstanding any provision of this Section 11.4 to the contrary, Seller shall not enter into any settlement or agreement in connection with any Indemnified Matters binding upon or adversely affecting Purchaser, or admit any liability or fact in controversy binding upon or adversely affecting Purchaser, without Purchaser's prior written consent which such consent shall not be unreasonably withheld or delayed.

SECTION 12. WAIVER. Any condition to the performance by any party hereto, which may legally be waived at or prior to the Closing may be waived at any time by the party entitled to the benefit thereof by action duly taken by the waiving party. Except as herein expressly provided, no waiver by a party of any breach of this Agreement or of any warranty or representation hereunder by the other party shall be deemed to be a waiver of any other breach by such other party (whether preceding or succeeding and whether or not of the same or similar nature) and no acceptance or payment or performance by a party after any breach by the other party shall be deemed to be a waiver of any breach of this

70

Agreement or of any representation or warranty hereunder by such other party whether or not the first party knows of such breach at the time it accepts such payment or performance. No failure or delay by a party to exercise any right it may have by reason of the default of the other party shall operate as a waiver of default or modification of this Agreement or shall prevent the exercise of any right by the first party while the other party continues to be so in default.

97

Landlord acquired the Premises on the date that the initial term of this Lease commenced and for the period of at least one year prior to said commencement date, Tenant owned, occupied and operated the Premises.

Tenant has determined that the same are satisfactory to Tenant, and Tenant accepts the Premises on an "AS IS WHERE IS" basis. TENANT ACKNOWLEDGES THAT LANDLORD (WHETHER ACTING AS LANDLORD HEREUNDER OR IN ANY OTHER CAPACITY) HAS NOT MADE AND WILL NOT MAKE, NOR SHALL LANDLORD BE DEEMED TO HAVE MADE, ANY WARRANTY OR REPRESENTATION, EXPRESS OR IMPLIED, WITH RESPECT TO ANY OF THE PREMISES, INCLUDING WITHOUT LIMITATION, ANY WARRANTY OR REPRESENTATION AS TO ITS FITNESS FOR USE OR PURPOSE, DESIGN OR CONDITION FOR ANY PARTICULAR USE OR PURPOSE, AS TO THE QUALITY OF THE MATERIAL OR WORKMANSHIP THEREIN, LATENT OR PATENT, AS TO LANDLORD'S TITLE THERETO, OR AS TO VALUE, COMPLIANCE WITH APPLICABLE LAWS, SPECIFICATIONS, LOCATION, USE, CONDITION, MERCHANTABILITY, QUALITY, DESCRIPTION, DURABILITY OR OPERATION, IT BEING AGREED THAT ALL RISKS INCIDENT THERETO ARE TO BE BORNE BY TENANT. Tenant acknowledges that the Premises are of its selection and to its specifications, and that the Premises have been inspected by Tenant and are satisfactory to it. In the event of any defect or deficiency in any of the Premises of any nature, whether patent or latent, Landlord shall not have any responsibility or liability with respect thereto or for any incidental or consequential damages (including strict liability in tort).

The Premises are Landlord's sole asset. The rents to be paid by Tenant to Landlord hereunder will be used by Landlord to, among other things, satisfy Landlord's obligations under the Loan Documents. It is, therefore, the parties' objective to provide for an absolute "Bond Type" net net net lease to Landlord; the Basic Rent (as hereinafter defined) payable by Tenant hereunder shall be an absolute "Bond Type" net net net return to Landlord and Tenant shall pay all costs and expenses relating to the Premises and Tenant's research and manufacturing operations carried on therein.

NOW, THEREFORE, IN CONSIDERATION of the aforesaid Recitals, and in consideration of the Premises leased by Landlord to Tenant hereby, and in consideration of the rents and covenants to be paid and performed by Tenant hereunder, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties covenant and agree as follows:

I. LEASE.

1.1. DEMISE OF PREMISES. In consideration of the rents and covenants herein stipulated to be paid and performed, Landlord hereby demises the Premises to Tenant, and Tenant hereby lets and accepts the Premises from Landlord, for the term herein described.

1.2. TITLE AND CONDITION. The Premises are demised and let "as is" subject to (a) the rights of any parties in possession and the existing state of the title as of the commencement of the term of this Lease, (b) any state of facts which an accurate survey or physical inspection thereof might show, (c) all zoning regulations, restrictions, rules and ordinances, building restrictions and other laws and regulations now in effect or hereafter adopted by any governmental authority having jurisdiction over the condition of any buildings, structures and other improvements located thereon, as of the commencement of the term of this Lease, without representation or warranty by Landlord. Tenant represents that it has examined the title to and the condition of the Premises and has found the same to be satisfactory to it.

98

1.3. USE OF LEASED PREMISES.

(a) Tenant may occupy and use the Premises for a research facility and related uses, including the manufacturing of pharmaceutical products, office uses, laboratories and light warehousing, or for any other lawful purpose, (except that the Premises may not be used for or associated with a pornographic shop, adult book store, or massage parlor) so long as such other lawful purpose would not (i) have a material adverse effect on the value of the Premises, (ii) increase (when compared to use as a research facility) the likelihood that Tenant, Landlord or Lender would incur liability under any provisions of any Environmental Laws, or (iii) result in or give rise to any material environmental deterioration or degradation of the Premises, including without limitation, mining or the removal of oil, gas or minerals, or (iv) violate any covenants, easement agreements, deed restrictions, agreements of record affecting the Premises or Applicable Laws. Tenant shall not create or suffer to exist any public or private nuisance, hazardous or illegal condition or waste on or with respect to the Premises. Tenant shall not use, occupy or permit any of the Premises to be used or occupied, nor do or permit anything to be done in or on any of the Premises, in a manner which would (A) make void or voidable any insurance which Tenant is required hereunder to maintain then in force with respect to any of the Premises, or (B) affect the ability of Tenant to obtain any insurance which Tenant is required to furnish hereunder, or (C) impair Landlord's title to the Premises, or in such manner as might reasonably make possible a claim or claims of adverse usage or adverse possession by the public, as such, or third Persons, or of implied dedication of the Premises or any portion thereof. Nothing contained in this Lease and no action by Landlord shall be construed to mean that Landlord has granted to Tenant any authority to do any act or make any agreement that may create any such third party or public right, title, interest, lien, charge or other encumbrance upon the estate of the Landlord in the Premises. The preceding sentence does not limit Tenant's right to assign or sublet its interest hereunder, as provided in Section 8.

(b) Tenant shall not conduct its business operation in the Premises unless and until (and only during such time as) all necessary certificates of occupancy, permits, licenses and consents from any and all appropriate governmental authorities have been obtained by Tenant and are in full force and effect.

1.4. QUIET ENJOYMENT. For so long as no Event of Default (as hereinafter defined) has occurred and is continuing hereunder, Landlord warrants peaceful and quiet enjoyment of the Premises by Tenant against acts of Landlord or anyone claiming through Landlord, provided that Landlord and its agents may enter upon and examine the Premises at reasonable times upon 24 hours prior notice, except in the event of a bona fide emergency. Exercise by Landlord of its rights to come upon the Premises as set forth in this Lease, including any limitations prescribed by federal law, shall not constitute a violation of this
Section 1.4.

II. TERM.

2.1. TERM. Subject to the terms and conditions hereof, Tenant shall have and hold the Premises for a primary term (herein called the "Primary Term") commencing on the date hereof, and ending at midnight on December 31, 2010. Thereafter, Tenant shall have the rights and options to extend this Lease for two (2) consecutive extended terms of five (5) years each (herein called the "Extended Terms" and individually, an "Extended Term," and together with the Primary Term, called the "Terms") upon the expiration of the Primary Term or the preceding Extended Term unless this Lease shall be sooner terminated pursuant to

Provided no Event of Default shall exist and be continuing at the time of exercise of such option, Tenant may exercise each said option to extend this Lease for an Extended Term by giving written notice to that effect at least eighteen (18) months prior to the expiration of the then existing term. Notwithstanding the foregoing, if Tenant fails to give notice to Landlord to extend the Term of the Lease within said eighteen (18) month period, Landlord shall give written notice to Tenant of said failure to give notice and Tenant shall have an additional thirty (30) days after said notice is given to exercise said Extended Term. If Tenant does not exercise any such option in a timely manner after such notice, then Landlord shall have the right during the remainder of the Term of this Lease to advertise the availability of the Premises for sale or reletting and to erect upon the Premises signs appropriate for the purpose of indicating such availability. The phrase "term of this Lease" or "term hereof" means the Primary Term, plus any Extended Terms with respect to which the right has been exercised. The term "Lease Year" shall mean such successive period of twelve (12) consecutive calendar months commencing on the "Commencement Date" (hereinafter defined). Except as otherwise expressly provided herein, all of the provisions of this Lease shall be applicable during each Extended Term.

Tenant shall, at its expense, comply with all changes required in order to obtain the Required Insurance (as hereinafter defined), and with the provisions of all contracts, agreements, instruments, easements, restrictions, reservations or covenants existing at the commencement of this Lease or thereafter suffered or permitted by Tenant affecting the Premises or any part thereof or the ownership, occupancy or use thereof.

For so long as the Note is outstanding, the escrow account for permitted contests shall be established with Lender or Lender's designee and the cost of such escrow shall be borne by Tenant.

If any Improvements situated on the Premises at any time during the Terms of this Lease shall encroach upon any property, street or right-of-way adjoining or adjacent to the Premises, or shall violate the agreements or conditions contained in any restrictive covenant affecting the Premises or any part thereof, or shall impair the rights of others under or hinder or obstruct any easement or right-of-way to which the Premises are subject, then, promptly after the written request of Landlord or any person affected by any such encroachment, violation, impairment, hindrance or obstruction, Tenant shall, at its expense, either (i) obtain effective waivers, or settlements of all claims, liabilities and damages resulting from each such encroachment, violation, impairment, hindrance or obstruction whether the same shall affect Landlord, Tenant or both, or (ii) make such changes in the improvements on the Premises and take such other action as shall be necessary to remove such encroachments, hindrances or obstructions and to end such violations or impairments, including, if necessary, the alteration or removal of any improvement on the Premises or (iii) obtain a waiver or consent to the encroachment or an encroachment permit or easement for the life of the encroachment. Any such alteration or removal shall be made in conformity with the requirements of Section 5.4 hereof to the same extent as if such alteration or removal were an alteration under the provisions of Section 5.4. Landlord shall cooperate and use its best efforts to cause Lender to cooperate in all transfers necessary to effectuate such matters.

5.4. ALTERATIONS.

(a) Tenant may, at its expense, make additions to and alterations of the Improvements to the Premises, and make substitutions and replacements therefore, provided that: (i) Landlord approves any addition to or structural alteration to the Premises, after having received from Tenant complete plans and specification for the proposed work, which such consent shall not be unreasonably withheld, (ii) the market value of the Premises shall not thereby be lessened; (iii) such addition or alteration is architecturally consistent with existing Improvements; (iv) such actions shall be performed in a good and workmanlike manner; (v) such work shall not violate any term of any restriction to which the Premises are subject or the requirements of any insurance policy required to be maintained by Tenant hereunder, and shall be expeditiously completed in compliance with all Applicable Laws; and (vi) no Improvements shall be demolished unless Tenant shall have first furnished Landlord with such surety bonds or other security acceptable to Landlord as shall be necessary to assure rebuilding of such Improvements. Notwithstanding the foregoing, Landlord's approval shall not be required for any nonstructural alterations costing less than One Hundred Thousand Dollars ($100,000.00). Tenant shall promptly pay all costs and expenses of each such addition, alteration, additional Improvement, substitution or replacement, discharge all liens arising therefrom and procure and pay for all permits and licenses required in connection therewith. All such additions, alterations, additional Improvements substitutions and replacements shall be and remain part of the realty and the property of Landlord and shall be subject to this Lease. Tenant may place upon the Premises any inventory, trade fixtures, machinery or equipment belonging to Tenant or third parties and may remove the same at any time during the Terms. Tenant shall repair any damage to the Premises caused by such removal.

5.5. NO LIENS. Tenant will not, directly or indirectly, create or permit to remain, and shall within thirty (30) days of filing of any, mechanics, contractors or other liens, discharge or bond, at its expense, any liens with respect to, the Premises or any part thereof or Tenant's interest therein or the Basic Rent, Additional Rent or other sums payable by Tenant under this Lease, other than any encumbrances permitted by a Permitted Encumbrance described in Section 11.12.

Notice is hereby given that Landlord will not be liable for any labor, services or materials furnished or to be furnished to Tenant, or to anyone holding the Premises or any part thereof, and that no mechanic's or other liens for any such labor services or materials shall attach to or affect the interest of Landlord in and to the Premises.

(a) Insurance against loss or damage to the Improvements (the "Improvements Insurance") under a fire and broad form of all risk extended coverage insurance policy (which shall include flood insurance if the Premises is located within a flood hazard area, and earthquake insurance if required by Lender and the Premises is located within an earthquake zone) together with an agreed value endorsement. Such insurance shall be in amounts equal to the full insurable value of the Improvements and not be less than the full replacement cost of the Improvements as determined from time to time by Landlord but not more frequently than once in any 12-month period. Such insurance policies shall contain a replacement cost endorsement and a waiver of depreciation, and may contain reasonable exclusions and deductible amounts as may be approved by Landlord.

Certificates of insurance with respect to all renewal and replacement policies shall be delivered to the Landlord not less than thirty (30) days prior to the expiration date of any of the insurance policies required to be maintained hereunder which certificates shall bear notations evidencing payment of applicable premiums. If Tenant fails to maintain and deliver to the Landlord the certificates of insurance required by this Lease, Landlord may, at its option, after written notice to Tenant, procure such insurance, and the Tenant shall reimburse Landlord for the amount of all premiums paid by Landlord thereon promptly, after demand by Landlord, with interest thereon at the Default Rate from the date paid by Landlord to the date of repayment.

110

6.2. PERMITTED INSURERS. The insurance required hereunder shall be written by companies of recognized financial standing authorized to do insurance business in the state in which the Premises are located and have a general policy rating of A or better and a financial class of IX or better by
A.M. Best Co. and a Standard and Poor's claims paying ability rating of AA or better, and shall name as the insured parties thereunder Landlord and Tenant, as their interests may appear, and Lender as an additional insured under a standard "mortgagee" endorsement or its equivalent satisfactory to Landlord. Landlord shall not be required to prosecute any claim against, or to contest any settlement proposed by, an insurer. Tenant may, at its expense, prosecute any such claim or contest any such settlement in the name of Landlord, Tenant or both with the consent of Landlord, and Landlord will join therein at Tenant's written request upon the receipt by Landlord of an indemnity from Tenant against all costs, liabilities and expenses in connection therewith.

6.3. INSURANCE CLAIMS. Insurance claims by reason of damage to or destruction of any portion of the Premises shall be adjusted by Tenant, both Landlord and Lender shall have the right to join with Tenant in adjusting any such loss.

6.4. INSURED PARTIES. Every policy referred to herein shall bear a first mortgage endorsement in favor of Lender; and any loss under any such policy shall be made payable to Lender, provided that any recovery under any such policy shall be applied by Lender in the manner provided in Section
6.3. Every policy of required insurance shall contain an agreement that the insurer will not cancel such policy except after thirty (30) days' prior written notice to Landlord and Lender and that any loss otherwise payable thereunder shall be payable notwithstanding any act or negligence of Landlord, Tenant or Lender which might, absent such agreement, result in a forfeiture of all or a part of such insurance payment and notwithstanding (i) any foreclosure or other action taken by a creditor pursuant to any provision of any Permitted Encumbrance upon the happening of a default or Event of Default thereunder or
(ii) any change in ownership of the Premises.

6.5. DELIVERY OF POLICIES. Tenant shall deliver to Landlord promptly after the delivery of this Lease, the original or certified duplicate policies or Acord-27 and Acord-25 form certificates of insurers, satisfactory to Lender, evidencing all of the Required Insurance. Tenant shall, at least fifteen
(15) days prior to the expiration of any such policy, deliver to Landlord other original or duplicate of such policy or certificates evidencing the renewal of any such policy. If Tenant fails to maintain or renew any required insurance, or to pay the premium therefor, or to deliver such certificate, then Landlord, at its option, but without obligation to do so, may, after giving Tenant notice thereof, procure such insurance. Any sums so expended by Landlord shall be Additional Rent hereunder and shall be repaid by Tenant within five (5) days after notice to Tenant of such expenditure and the amount thereof.

6.6. NO DOUBLE COVERAGE. Neither Tenant nor Landlord shall obtain or carry separate insurance covering the same risks as any Required Insurance unless Tenant, Landlord and Lender are included therein as named insured, with loss payable as provided in this Lease and the policy contains a first mortgagee endorsement in favor of the Lender. Tenant and Landlord shall immediately notify each other whenever any such separate insurance is obtained and shall deliver to each other the policies or certificates evidencing the same.

6.7. BLANKET INSURANCE. Anything contained in this Article VI to the contrary notwithstanding, all Required Insurance may be carried under a "blanket" or "umbrella" policy or policies covering other property or liabilities of Tenant, provided that such policies otherwise comply with the provisions of this Lease and specify the coverage and amounts thereof with respect to the Premises.

111

6.8. DAMAGES FOR TENANT'S FAILURE TO PROPERLY INSURE. Landlord or Lender shall not be limited in the proof of any damages which Landlord or Lender may claim against Tenant arising out of or by reason of Tenant's failure to provide and keep in force insurance, as provided above, to the amount of the insurance premium or premiums not paid or incurred by Tenant and which would have been payable under such insurance; but Landlord and Lender shall also be entitled to recover as damages for such breach, the uninsured amount of any loss, to the extent of any deficiency in the Required Insurance and damages, costs and expenses of suit suffered or incurred by reason of or damage to, or destruction of, the Premises, occurring during any period when Tenant shall have failed to provide the Required Insurance. Tenant shall indemnify and hold harmless Landlord and Lender for any liability incurred by Landlord or Lender arising out of any deductibles for Required Insurance.

6.9. CASUALTY. If all or any part of the Premises shall be damaged or destroyed by casualty, Tenant shall promptly notify Landlord and Lender thereof within five (5) Business Days, and shall, with reasonable promptness and diligence, rebuild, replace and repair any damage or destruction to the Premises, at its expense, in conformity with the requirements of Section 5.4(a) hereof, in such manner as to restore the same to the same or better condition as existed prior to such casualty, using materials of the same or better grade than that of the materials being replaced, and there shall be no abatement of Basic Rent or Additional Rent. Proceeds of casualty insurance of $100,000.00 or less shall be paid to Tenant. Proceeds in excess of $100,000.00 shall be held by Landlord or a proceeds trustee (which shall be Lender or Lender's designee for so long as the Note is outstanding, or an escrow or title company, or a bank or trust company designated by Landlord thereafter) and paid to Tenant, but only against certificates of Tenant and appropriate lien waivers delivered to Landlord from time to time, but not more frequently than once per calendar month, as such work or repair progresses. Each such certificate shall describe the work or repair for which Tenant is requesting payment and the cost incurred by Tenant in connection therewith and stating that Tenant has not theretofore received payment for such work and has sufficient funds remaining to complete the work free of liens or claims. Any proceeds remaining after Tenant has repaired the Premises shall be delivered to Landlord; provided, however, that if such aggregate amounts exceed One Hundred Thousand Dollars ($100,000), the excess shall, at Lender's direction and with Lender's written consent at its sole discretion, be applied in reduction of the principal amount of the Note or paid to Tenant; provided further, however, that no payment shall be made to Tenant if any material or monetary default or Event of Default shall have happened and be continuing under this Lease. If the excess is applied to the remaining principal outstanding under the Note, the Note shall be reamortized and monthly payment of Basic Rent payable on or after the second Basic Rent Payment Date occurring after such application shall be reduced in an amount equal to the amount by which the monthly payment under the Note has been reduced. The foregoing references to "Note" shall mean the Note and any future promissory note that may be issued in connection with a refinancing of the Mortgage

6.10. INDEMNIFICATION.

(a) Tenant agrees to pay, and to protect, defend, indemnify and save harmless Landlord, Lender and their agents from and against any and all liabilities, losses, damages, costs, expenses (including all reasonable attorneys' fees and expenses of Landlord and Lender), causes of action, suits, claims, demands or judgments of any nature whatsoever that may be suffered or imposed on or asserted against any of them (i) arising from any injury to, or the death of, any person or damage to property (including property of employees and invitees of Tenant) on the Premises or upon adjoining sidewalks, streets or ways or elsewhere, in any manner growing out of or connected with the use, non-use, condition or occupation of the Premises or any part thereof, so long as not occasioned by the gross negligence or willful misconduct of Landlord, Lender, their agents, servants, employees or assigns, and/or (ii) arising from violation by Tenant of any agreement or condition of this Lease, or any contract

112

or agreement to which Tenant is a party or any restriction, law, ordinance or regulation, including without limitation, the Americans With Disabilities Act of 1990 and all regulations issued thereunder, in each case affecting the Premises or any part thereof or the ownership, occupancy or use thereof, so long as not occasioned by the negligence or willful misconduct of Landlord, Lender, their agents, servants, employees or assigns; (iii) arising out of any permitted contest referred to in Section 4.3 (collectively, "Indemnified Matters"). If Landlord, Lender or any agent of Landlord or Lender shall be made a party to any such litigation commenced against Tenant, and if Tenant, at its expense, shall fail to provide Landlord, Lender or their agents with counsel (upon Landlord's request) reasonably approved by Landlord, Tenant shall pay all costs and attorneys' fees and expenses incurred or paid by Landlord, Lender or their agents in connection with such litigation. Tenant's obligations and liabilities under this Section 6.10 shall survive the expiration of this Lease. Tenant waives all claims against Landlord arising form any liability described in this
Section 6.10 (a), except to the extent caused by the negligence or willful misconduct of Landlord, Lender, their agents, servants, employees or assigns. The waiver and indemnity provisions in this paragraph are intended to exculpate and indemnify each of Landlord and Lender (i) from and against the consequences of its own negligence or fault when Landlord or Lender are solely negligent or contributorily, partially, jointly, comparatively or concurrently negligent with Tenant or any other person (but is not solely or grossly negligent, has not committed an intentional act or made an intentional omission) and (ii) from and against any liability of Landlord or Lender based on any applicable doctrine of strict liability.

(b) Should any claim be made against Landlord by a person not a party to this Lease with respect to any Indemnified Matter, Landlord shall promptly give Tenant written notice of any such claim, and Tenant shall thereafter defend or settle any such claim, at its sole expense, on its own behalf and with counsel of its selection; provided, however, that Tenant's counsel shall be competent counsel experienced in the type of litigation or claim at issue and shall be acceptable to Landlord, acting reasonably. Upon Tenant's assumption of the defense of any claim against Landlord pursuant to Tenant's indemnity, Landlord shall have the right to participate in the defense or settlement of the claim with counsel retained and paid by it, and Tenant shall cause the attorneys retained by it to consult and cooperate fully with counsel for Landlord. In such defense or settlement of any claims, Landlord shall provide Tenant with originals or copies of all relevant documents and shall cooperate with and assist Tenant, at no expense to Landlord. Notwithstanding any provision of this Section 6.10 to the contrary, Tenant shall not enter into any settlement or agreement in connection with any Indemnified Matters binding upon or adversely affecting either Landlord or Lender, or admit any liability or fact in controversy binding upon or adversely affecting either Landlord or Lender, without the prior written consent of Landlord or Lender, as the case may be, in such party's sole discretion.

VII. CONDEMNATION.

7.1. ASSIGNMENT OF AWARD. Subject to the rights of Tenant set forth in this Article VII, Tenant hereby irrevocably assigns to Landlord any award or payment to which Tenant may be or become entitled with respect to Complete, Partial or Temporary Taking (all as hereinafter defined) of the Premises or any part thereof, by condemnation or other eminent domain proceedings pursuant to any law, general or special, by any governmental authority, whether the same shall be paid or payable in respect of Tenant's leasehold interest hereunder or otherwise. Landlord and Tenant agree that as long as the Note is outstanding, Lender shall hold all proceeds until disbursed pursuant to the terms hereof. Landlord and Lender shall be entitled to participate in any such proceeding and the expenses thereof (including counsel fees and expenses) shall be paid by Tenant.

7.2. DEFINITIONS FOR ARTICLE VII.

113

(a) "Complete Taking" shall mean the occurrence of any actual or threatened condemnation or other eminent domain proceeding pursuant to any general or special law, or any agreement with an authority having the power of eminent domain, which results in the taking or conveyance of (i) the entire Premises or (ii) such a significant portion of the Premises that, in the good faith judgment of Tenant, it is uneconomic to rebuild or restore the remaining portion of the Premises for the continued operation of the Premises.

(b) "Partial Taking" shall mean the occurrence of any taking of a portion of the Premises by condemnation or other eminent domain proceedings, or any agreement with an authority having the power of eminent domain, which does not result in a Complete Taking.

(c) "Temporary Taking" shall mean the occurrence of a temporary taking of the use or occupancy of the Premises or any part thereof by any governmental authority.

(d) "Net Award" shall mean all amounts payable as a result of any condemnation or other eminent domain proceeding and all amounts payable pursuant to any agreement with any condemning authority (which agreement shall be deemed to be a taking) which has been made in settlement of or under threat of any condemnation or other eminent domain proceeding affecting the Premises, less all expenses incurred as a result thereof not otherwise paid by Tenant and the collection of such amounts.

(e) "Purchase Offer" shall mean a purchase offer as described in this Article VII with a Purchase Price hereafter defined.

7.3. COMPLETE TAKING. Upon the occurrence of a Complete Taking, Tenant shall deliver a Purchase Offer to Landlord, with a copy to Lender, specifying a Termination Date occurring not less than thirty (30) nor more than one hundred eighty (180) days after the delivery of such Purchase Offer and this Lease shall continue in full force and effect without any abatement of rent, notwithstanding any taking, until the Termination Date as defined herein. The Purchase Offer shall contain a purchase price ("Purchase Price") which is the greater of the Net Award or the lesser of (a) Landlord's acquisition cost of the Premises, or (b) the amount of the first mortgage against the Premises, including any prepayment penalties, plus Landlord's unamortized equity in the Premises based on a twenty year term at 7%, plus the reasonable out-of-pocket expenses of Landlord and Lender relating to the purchase, and shall be accompanied by a Tenant's Certificate stating that a "Complete Taking" has occurred within the meaning of clause (a) of Section 7.2. Notwithstanding anything contained herein to the contrary, in no event shall the Purchase Price be less than the full amount due Lender under the Loan Documents. If Tenant shall fail to deliver a Purchase Offer as required above, Tenant shall be conclusively presumed to have made a Purchase Offer on a date which is one hundred twenty (120) days after any such taking (or such later date as is agreed to in writing by Landlord), and in the event Tenant is so presumed to have made a Purchase Offer, the Termination Date shall be deemed to be one hundred fifty
(150) days after such Purchase Offer is presumed to have been made; but nothing in this sentence shall relieve Tenant of its obligation actually to deliver such Purchase Offer. No Basic Rent or Additional Rent shall abate through the Termination Date.

7.4. PARTIAL TAKING. Upon the occurrence of any Partial Taking, this Lease shall continue in full effect without abatement or reduction of Basic Rent, Additional Rent or other sums payable by Tenant. In the event Landlord receives a Net Award in connection with any such Partial Taking, Landlord shall make the Net Award available to Tenant to make any repairs required by Section 5.4 hereof so that, thereafter, the Premises shall be, as

114

nearly as possible, in a condition as good as the condition thereof immediately prior to such Partial Taking, but, if such Net Award shall be in excess of One Hundred Thousand Dollars ($100,000), only if there is no default or Event of Default and Tenant delivers to Landlord of (i) certificates of Tenant identifying the repair work for which Tenant is requesting payment and the cost incurred by Tenant in connection therewith and stating that Tenant has not theretofore received payment for such work; and (ii) appropriate lien waivers. Any Net Award remaining after such repairs have been made shall be delivered to Tenant; but only to the extent that the aggregate amount of such Net Award so remaining and all amounts theretofore paid to Tenant pursuant to this sentence do not exceed One Hundred Thousand Dollars ($100,000). If such amounts exceed One Hundred Thousand Dollars ($100,000), the excess may, at Lender's direction and with Lender's written consent at its sole option, be applied in reduction of the outstanding principal amount of the Note, in accordance with the terms of the Loan Documents. If the excess is applied to the remaining principal outstanding under the Note, the Note shall be reamortized and monthly payment of Basic Rent payable on or after the second Basic Rent Payment Date occurring after such application shall be reduced in an amount equal to the amount by which the monthly payment under the Note has been reduced.

7.5. TEMPORARY TAKING. Upon the occurrence of any Temporary Taking, Tenant shall, promptly after any such Temporary Taking ceases, at its expense, repair any damage caused thereby in conformity with the requirements of
Section 5.4 hereof so that, thereafter, the Premises shall be, as nearly as possible, in a condition as good as the condition thereof immediately prior to such Temporary Taking. In the event of such Temporary Taking, Tenant shall be entitled to receive the entire Net Award payable by reason of such Temporary Taking, less any costs incurred by the Landlord in connection therewith. If the cost of any repairs required to be made by Tenant pursuant to this Section 7.5 shall exceed the amount of the Net Award, the deficiency shall be paid by Tenant. No payments shall be made to Tenant pursuant to this Section 7.5, if any default or Event of Default shall have happened and shall be continuing under this Lease. Basic Rent shall abate through the duration of such Temporary Taking.

7.6. PROCEDURE AFTER PURCHASE OFFER; PROCEDURE ON EVENT OF PURCHASE.

(a) If Landlord shall have accepted the Purchase Offer in writing, Landlord shall convey the Premises to Tenant for the Purchase Price contained therein, giving due credit, if any, against such Purchase Price to Tenant for any Net Award received and retained by Landlord.

(b) If the Premises or any part thereof shall be purchased by Tenant under Article VII of this Lease, Landlord need not transfer and convey to Tenant or its designee any better title thereto than existed on the date of the commencement of this Lease, and Tenant shall accept such title, subject, however, to such liens, encumbrances, charges, exceptions and restrictions, against or relating to the Premises, (i) including those arising pursuant to the terms of this Lease and (ii) subject to all applicable laws, regulations and ordinances, but free of the Mortgage and all other mortgages, liens, encumbrances, charges, exceptions and restrictions which shall have been created by or resulted from acts or failures to act of Landlord.

(c) On the date fixed for any such purchase, which shall be the next Payment Date as defined in the Loan Commitment, Tenant shall pay to Landlord, at any place within the United States of America designated by Landlord before 2:00 P.M. Pacific Time, the Purchase Price therefor, in immediately available funds, together with all installments of Basic Rent and all other sums then due under this Lease and unpaid to and including the purchase date without offset or deduction for any reason, and Landlord shall deliver to Tenant: (i) a special grant deed conveying title to the Premises and describing the Premises or portion thereof being sold and conveying the title thereto; (ii) such instruments as shall be necessary to transfer to Tenant or its designee any other property then required to be transferred by Landlord

115

pursuant to this Lease; and (iii) an assignment of condemnation awards due in connection with the Property, but not yet paid to the Landlord or Lender. Tenant shall pay all charges incident to such conveyance and transfer, including Landlord and Lender's reasonable counsel fees, escrow fees, recording fees, title insurance premiums and all applicable federal, state and local taxes (other than any income, sales, rental receipts, or franchise taxes levied upon or assessed against Landlord) which may be incurred or imposed by reason of such conveyance and transfer.

(d) Upon the completion of such purchase, but not prior thereto, this Lease and all obligations hereunder (including the obligations to pay Basic Rent and Additional Rent) shall terminate, except with respect to any obligations and liabilities of Tenant, actual or contingent, under this Lease which arose on or prior to such date of purchase, and with respect to such obligations and liabilities they shall survive the Termination of the Lease.

(e) If Landlord (with the written consent of Lender) shall have tendered a written rejection of the Purchase Offer not later than the tenth (10th) day prior to the Termination Date specified in such Purchase Offer, this Lease shall terminate on such Termination Date (except with respect to obligations and liabilities of Tenant under this Lease, actual or contingent, which have arisen on or prior to such Termination Date), upon payment by Tenant of all of the Basic Rent, Additional Rent and all other sums due and payable hereunder to and including the Termination Date without offset or deduction for any reason. If Landlord shall fail to accept or reject the Purchase Offer within the times allotted, Landlord shall be conclusively presumed to have accepted the Purchase Offer.

7.7. COMPENSATION FOR PERSONAL PROPERTY AND RELOCATION EXPENSES. Tenant shall have the right to claim and recover from the condemning authority any such compensation as may be awarded to Tenant for the value of furniture, equipment owned by Tenant, removal of merchandise, moving and relocation expenses, goodwill, or damage to Tenant's research and development operations conducted at the Premises.

VIII. ASSIGNMENT AND SUBLETTING.

8.1. POWER TO ASSIGN AND SUBLET. Provided that no Event of Default shall be continuing and Landlord shall have first given its consent thereto, which such consent shall not be unreasonably withheld or delayed, Tenant may assign all its rights and interests under this Lease or sublet all or any part of the Premises (provided that each such assignment or sublease is expressly made subject to all of the provisions, including the use provisions of
Section 1.3 of this Lease) and may assign all its rights and interests under this Lease. Tenant shall, within ten (10) days after the execution and delivery of any such assignment or the sublease of all or substantially all of the Premises, deliver a conformed copy thereof to Landlord. Within ten (10) days after the execution and delivery of any sublease of a portion of the Premises, Tenant shall give notice to Landlord of the existence and term thereof, and of the same name and address of the sublessee thereunder. Such sublease shall not relieve Tenant of any responsibilities or obligations of the Lease. Tenant shall comply with all the terms and provisions of any sublease.

8.2. ASSUMPTION BY ASSIGNEE OR TRANSFEREE; TENANT REMAINS LIABLE. If Tenant assigns all its rights and interests under this Lease, or sells or otherwise transfers all of substantially all of its assets as set forth in Section 11.7, the transferee or the assignee under such assignment shall expressly assume all the obligations of Tenant hereunder in an instrument delivered to Landlord at the time of such assignment. No assignment or sublease made as permitted by this Article VIII or merger, consolidation, sale or transfer of assets made as set forth in Section 11.7 shall affect or reduce any of the obligations of Tenant hereunder, and all such obligations shall continue

116

in full force and effect as obligations of a principal and not as obligations of a guarantor or surety, to the same extent as though no assignment, subletting, merger, consolidation, sale or transfer of assets had been made, provided that performance by any such assignee, sublessee, surviving Person or transferee of any of the obligations of Tenant under this Lease shall be deemed to be performance by Tenant. No sublease or assignment made as permitted by this Article VIII or merger, consolidation, or sale or transfer of assets made as permitted by Section 11.7 shall impose any obligations on Landlord or otherwise affect any of the rights of Landlord under this Lease. At Landlord's option, the assignee, sublessee, surviving Person or transferee, as applicable, shall have direct responsibility to Landlord and shall have the same obligations of Tenant as required under this Lease.

8.3. OTHER TRANSFERS VOID. Except as hereafter provided, neither this Lease nor the Term hereby demised shall be mortgaged by Tenant, nor shall Tenant mortgage or pledge the interest of Tenant in and to any sublease of the Premises or the rentals payable thereunder. Any mortgage, pledge, sublease or assignment made in violation of this Article VIII shall be void. Notwithstanding the foregoing, Tenant may, without Landlord's consent, mortgage, pledge or convey a security interest in Tenant's leasehold interest in the Premises ("Leasehold Mortgage") for financing purposes. As used in this Section 8.3, the term "Leasehold Mortgage" shall mean a deed of trust, mortgage or other instrument encumbering Tenant's leasehold. A Leasehold Mortgage shall be subject to all of the terms and conditions stated in this Lease and to all rights and interests of Landlord. No Leasehold Mortgage shall extend to or otherwise affect the interest or estate of Landlord in and to the Premises. Prior to the time of the recordation of a Leasehold Mortgage, Tenant shall deliver a copy thereof to Landlord, together with a written notice containing the name and address of Tenant's lender.

10.2. LANDLORD'S REMEDIES.

(a) If an Event of Default shall have happened and be continuing, Landlord shall have the right at its election to give Tenant twenty
(20) days written notice of Landlord's intention to terminate the term of this Lease on a date specified in such notice. Thereupon, the term of this Lease and the estate hereby granted shall terminate on such date as completely and with the same effect as if such date were the date fixed herein for the expiration of the term of this Lease, and all rights of Tenant hereunder shall terminate, but Tenant shall remain liable as provided herein.

118

(b) If an Event of Default shall have happened and be continuing Landlord shall have the immediate right, whether or not the term of this Lease shall have been terminated pursuant to Section 10.2(a), to (i) re-enter and repossess the Premises or any part thereof by any means permissible under California law, (ii) remove all persons and property therefrom, Tenant hereby expressly waiving any and all notices to quit, cure or vacate provided by current or any future law; and (iii) collect from Tenant all sums due hereunder, plus interest at the Default Rate. Landlord shall be under no liability by reason of any such re-entry, repossession or removal. No such re-entry or taking of possession of the Premises by Landlord shall be construed as an election on Landlord's part to terminate the term of this Lease unless a written notice of such intention to be given to Tenant pursuant to Section 10.2(a).

(c) At any time or from time to time after the repossession of the Premises or any part thereof pursuant to Section 10.2(b), whether or not the term of this Lease shall have been terminated pursuant to
Section 10.2(a), Landlord may relet the Premises or any part thereof for the account of Tenant, in the name of Tenant or Landlord or otherwise, without notice to Tenant, for such term or terms (which may be greater or less than the period which would otherwise have constituted the balance of the term of this Lease) and on such conditions (which may include concessions or free rent) and for such uses Landlord, in its absolute discretion, may determine, and Landlord may collect and receive any rents payable by reason of such reletting.

(d) No termination of the term of this Lease pursuant to
Section 10.2(a), by operation of law or otherwise, and no repossession of the Premises or any part thereof pursuant to Section 10.2(b) or otherwise, and no reletting of the Premises or any part thereof pursuant to Section 10.2(c), shall relieve Tenant of its liabilities and obligations hereunder, all of which shall survive such expiration, termination, repossession or reletting.

(e) At any time after such termination or repossession by reason of the occurrence of any Event of Default, whether or not Landlord shall have collected any current damages pursuant to this Section 10.2(e), Landlord shall be entitled to recover from Tenant, and Tenant will pay to Landlord on demand, as and for liquidated and agreed final damages for Tenant's default and in lieu of all current damages beyond the date of such demand (it being agreed that it would be impracticable or extremely difficult to fix the actual damages), an amount equal to the present value of all rent payable under the Lease beyond the date of such demand over the then present value of the then fair market rental for the Premises, at the date of such demand for what would be the unexpired term of the Lease, which present value shall in each case be determined by the application of a discount factor of five percent (5%) per annum; however, this amount shall not be less than any "make whole provision" in favor of the Lender, including without limitation, any yield maintenance premium, default interest and late charges specified in the Loan Documents in connection with the indebtedness encumbered by the Premises. If any law, including without limitation, California Civil Code Section 1951.2 or its successor, shall be construed to limit the amount of such liquidated final damages to less than the amount above agreed upon, Landlord shall be entitled to the maximum amount allowable under such statute or rule of law. Landlord retains all remedies described in California Civil Code Section 1951.4.

(f) Notwithstanding anything to the contrary stated herein, if an Event of Default shall have happened and be continuing, whether or not Tenant shall have abandoned the Premises, Landlord may elect to continue this Lease in effect for so long as the Landlord does not terminate Tenant's right to possession of the Premises and Landlord may enforce all of its rights and remedies hereunder including, without limitation, the right to recover all Basic Rent, Additional Rent and other sums payable hereunder as the same become due

119

10.3. ADDITIONAL RIGHTS OF LANDLORD. No right or remedy herein conferred upon or reserved to Landlord is intended to be exclusive of any other right or remedy, and each and every right and remedy shall be cumulative and in addition to any other right or remedy given hereunder or now or hereafter existing at law or in equity or by statute. The failure of Landlord to insist at any time upon the strict performance of any covenant or agreement or to exercise any option, right, power or remedy contained in this Lease shall not be construed as waiver or a relinquishment thereof for the future. A receipt by Landlord of any Basic Rent, any Additional Rent or any other sum payable hereunder with knowledge of the breach of any covenant or agreement contained in this Lease shall not be deemed a waiver of such breach, and no waiver by Landlord of any provision of this Lease shall be deemed to have been made unless expressed in writing and signed by Landlord. In addition to other remedies provided in this Lease, Landlord shall be entitled, to the extent permitted by applicable law, to injunctive relief in case of the violation, or attempted or threatened violation, of any of the covenants, agreements, conditions or provisions of this Lease, or to a decree compelling performance of any of the covenants, agreements, conditions or provisions of this Lease, or to any other remedy allowed to Landlord at law or in equity.

10.4. WAIVERS BY TENANT. Tenant hereby waives and surrenders for itself and all those claiming under it, including creditors of all kinds,
(i) any right or privilege which it or any of them may have under any present or future construction, statute or rule of law to redeem the Premises or to have a continuance of this Lease for the term hereby demised after termination of Tenant's right of occupancy by order or judgment of any court or by any legal process or writ, or under the terms of this Lease or after the termination of the term of this Lease as herein provided, and (ii) the benefits of any present or future constitution, statute or rule of law which exempts property from liability for debt or for distress for rent.

10.5. ATTORNEYS' FEES. In the event an action shall be brought for the enforcement of any right set forth herein in connection with, and subject to, the indemnification provisions contained in Section 6.10 hereof, the non-prevailing party shall be liable for all of the reasonable expenses incurred in connection therewith, including without limitation, reasonable attorneys' fees.

120

XI. MISCELLANEOUS.

11.1. NOTICES, DEMANDS AND OTHER INSTRUMENTS. All notices, demands, requests, consents, approvals and other instruments required or permitted to be given pursuant to the terms of this Lease shall be in writing and shall be deemed to have been properly given if (a) with respect to Tenant, sent by registered or certified mail with a return receipt requested, postage prepaid, or sent by facsimile, nationally recognized overnight express carrier or delivered by hand, in each case addressed to Tenant at its notice address first above set forth, and (b) with respect to Landlord, sent by registered or certified mail with a return receipt request, postage prepaid, or sent by facsimile, nationally recognized overnight express courier or delivered by hand in each case, addressed to the Landlord at its address first above set forth along with a copy to Lender: Finova Capital Realty, Inc., a Delaware corporation,19900 MacArthur Boulevard, Suite 1100, Irvine, California 92612, and Lender's Legal Counsel: Paul Hastings Janofsky & Walker, LLP, 695 Town Center Drive, 17th Floor, Costa Mesa, California 92626-1924 Landlord and Tenant shall each have the right from time to time to specify as its address for purposes of this Lease any other address in the United States of America upon giving fifteen (15) days written notice thereof, similarly given, to the other party. Notices shall be deemed communicated upon the earlier of receipt, or seventy-two (72) hours from the time of mailing if mailed as provided in this
Section 11.1 and on the Business Day or first Business Day following transmission if given by facsimile.

11.2. ESTOPPEL CERTIFICATES AND CONSENTS.

(a) Tenant and Landlord will, from time to time, upon not less than twenty (20) days prior request by Landlord or by Lender, execute, acknowledge and deliver to the other party a Certificate in the form of Exhibit "C" attached hereto certifying: (i) that this Lease is unmodified and in full effect (or setting forth any modifications along with the statement that this Lease as modified is in full effect ); (ii) that the Basic Rent and Additional Rent payable and the dates to which the Basic Rent, Additional Rent and other sums payable hereunder have been paid and the most recent dates on which the Basic Rent, Additional Rent and other sums payable hereunder have been paid;
(iii) that to the knowledge of Tenant, Landlord is not in any default of the Lease which Tenant may have knowledge; (iv) the commencement and expiration dates of the Lease; (v) the amount of any security or other deposits; (vi) that either Tenant is in possession of the Premises or who is in possession; (vii) any concessions or other rights that Tenant (including first refusal, option or other occupancy claims) or Landlord may have; and (viii) such other matters as may reasonably be required by the requesting party. Any such certificate may be relied upon by any mortgagee, prospective purchaser, or prospective mortgagee of the Premises. Tenant further agrees to reasonably cooperate with Lender and its affiliates in the preparation and review of disclosure documents which may be issued in connection with a secondary market transaction involving a sale or securitization of the Loan. Landlord will be responsible for any reasonable outside legal or accounting costs incurred by Tenant in connection with such cooperation, in an amount not to exceed $2,500.00 unless otherwise approved by Landlord.

(b) From time to time during the term of this Lease, Landlord expects to secure financing of its interest in the Premises by assigning Landlord's interest in this Lease and the sums payable hereunder. In the event of any such assignment to Lender, Tenant will, upon not less than ten
(10) days prior request by Landlord, execute, acknowledge and deliver to Landlord a consent clearly indicating (i) that Tenant is to make Basic Rent payments or portions thereof directly to Lender or Lender's designee if required by Lender, and (ii) consent to such assignment addressed to such lender in a form satisfactory to Lender; and Tenant will use its best efforts to produce, at Tenant's expense, such certificates, opinions of counsel and other documents as may be reasonably requested by Lender, at a cost not to exceed $2,500. Notwithstanding the foregoing, Landlord will contribute one-half the cost of any opinion of counsel requested by Lender. Tenant acknowledges that, by execution hereof, it has agreed to make payments of Basic Rent or portions thereof directly to Lender or Lender's designee, without further notice or direction if required by Lender.

121

11.3. DETERMINATION OF FAIR MARKET VALUE. Fair market value for purposes of Section 11.7.1 hereof shall be determined by an appraisal, which shall be performed by an appraiser selected by Landlord, and paid by Tenant. Any appraiser selected by Landlord shall have qualifications that include a minimum of five (5) years of experience in the appraisal of commercial real estate in Orange County. Such appraiser shall be disinterested, and shall be a member of a nationally recognized appraisal association. Further, any such appraiser shall comply with the licensing law then in effect for appraisers authorized to perform general appraisals within the State of California. If there are then any existing United States laws governing appraisers, said appraiser shall be in compliance with the then applicable Federal laws for appraisers performing appraisals of commercial real estate. In the event that Tenant disputes the appraised fair market value determined by an appraiser (hereinafter the "First Appraiser"), who performed an appraisal pursuant to this Section 11.3, it shall so notify Landlord within five (5) days after receipt of such written determination by the First Appraiser, and the disagreement shall be resolved as follows:

(a) Within five (5) days after the service of such notice by Tenant to Landlord, Tenant shall designate a second appraiser (the "Second Appraiser"), who shall appraise the fair market value of the Premises, assuming the provisions of this Lease (except the Basic Rent provision) would govern for a five (5) year term, all in accordance with the requirements of this
Section 11.3. This Second Appraiser shall render its opinion of the fair market value no later than thirty (30) days after the service of notice by Tenant stated above. In the event that the higher of the two appraised fair market values rendered herein is not more than ten percent (10%) greater than the lower of the two appraised fair market rental values, then the mean between the two appraised values shall be utilized to fix the appraised fair market value.

(b) In the event that the higher of the two appraised fair market values is more than ten percent (10%) higher than the lower of the two appraised fair market rental values, then the First Appraiser and the Second Appraiser will meet within five (5) days after receipt and acceptance of the Second Appraisal by Tenant, to attempt to agree upon the appraised fair market value. If the First Appraiser and Second Appraiser do not agree upon the appraised fair market value after such meeting, then they shall appoint a third appraiser (the "Third Appraiser").

(c) If the First and Second Appraiser shall be unable to agree upon the appointment of the Third Appraiser within five (5) days after the time specified in subsection "(ii)" above, then the Third Appraiser shall be selected by the Tenant and Landlord themselves. If Tenant and Landlord cannot agree on the third appraiser, within a further period of five (5) days, then either, on behalf of both, may apply to the person who is, at the time, the most senior in service, active Judge of the United States District Court for the District of where the Premises are located, for the selection of the Third Appraiser. If that Judge cannot or will not make the appointment, then the application will be made to the next most senior Judge, and so on down the line of seniority. The fees and costs of the Second Appraiser and the Third Appraiser will be borne by Tenant, and the cost of application to the Judge of the United States District Court shall be borne by Tenant. In the event of the failure, refusal or inability of any appraiser to act, a new appraiser shall be appointed in this stead, which appointment shall be made in the same manner as provided herein; e.g., if the Second Appraiser must be replaced, then Tenant will have the right to designate its replacement. In the event that a Third Appraiser is selected in the manner aforesaid, it shall perform an appraisal of the fair market value of the Premises in accordance with the terms of this Section 11.3 within thirty (30) days after its appointment. In the event that the appraised fair market rental value rendered by the Third Appraiser is higher than the lower appraised fair market value, but lower than the higher appraised fair market value, as rendered by the First Appraiser and the Second Appraiser, then the appraised fair market value rendered by the Third Appraiser shall become the appraised value. In the event that the appraised value rendered by the Third Appraiser is lower than the lower appraised value or higher than the higher appraised fair value, as rendered by the First Appraiser and Second Appraiser, than an Appraisal Panel shall be convened.

122

The "Appraisal Panel," consisting of the First, Second and Third Appraiser, shall convene within five (5) days after submission of a written appraisal to Landlord and Tenant by the Third Appraiser (which Third Appraisal does not resolve the appraised fair market value question in accordance with this Section 11.3). The purpose of the formation of the Appraisal Panel will be to attempt to reach a decision by two members of the Appraisal Panel on the appraised fair market value. A decision joined in by any two of the appraisers of the Appraisal Panel shall be the decision of the Appraisal Panel, and shall be binding upon the parties hereto. If no two members of the Appraisal Panel can concur in a decision of the appraised fair rental value within ten (10) days after the submission of the appraisal by the Third Appraiser to the parties, then the parties shall go to a neutral mediator for mediation. If the parties are unable to agree upon a fair market value through mediation, the matter will be submitted to binding arbitration under the expedited rules of the American Arbitration Association.

11.4. NO MERGER. There shall be no merger of this Lease or the leasehold estate hereby created with the fee estate in the Premises or any part thereof by reason of the same person acquiring or holding, directly or indirectly, this Lease or the leasehold estate hereby created or any interest in this Lease or in such leasehold estate as well as the fee estate in the Premises or any portion thereof.

11.5. SURRENDER. Upon the termination of this Lease, Tenant shall peaceably surrender the Premises to Landlord in good and marketable condition, fully operational as a standard, fully air-conditioned research and development building. Tenant shall remove from the Premises prior to or within a reasonable time after such termination (not to exceed thirty (30) days) all its property that is capable of removal without causing damage to the Premises, and, at Tenant's expense, shall at such times of removal, repair any damage caused by such removal. Property not so removed shall become the property of Landlord. Landlord may thereafter cause such property to be removed and disposition of and the cost of repairing any damage caused by such removal shall be borne by Tenant. Notwithstanding anything to the contrary contained herein, upon termination of this Lease pursuant to a default by Tenant, the heating, ventilation and air conditioning systems shall remain on the Premises and shall become the property of Landlord. Any holding over by Tenant of the Premises after the expiration or earlier termination of the term of this Lease or any extensions thereof, with the consent of Landlord, shall operate and be construed as a tenancy from month to month only, at one hundred twenty-five percent (125%) of the Basic Rent reserved herein and upon the same terms and conditions as contained in this Lease. Notwithstanding the foregoing, any holding over without Landlord's consent shall entitle Landlord, in addition to collecting Basic Rent at a rate of one hundred twenty- five percent (125%) thereof, to exercise all rights and remedies provided by law or in equity.

11.6. SEPARABILITY. Each and every covenant and agreement contained in this Lease is separate and independent, and the breach of any thereof by Landlord shall not discharge or relieve Tenant from any obligation hereunder. If any term or provision of this Lease or the application thereof to any person or circumstances or at any time to any extent be invalid and unenforceable, the remainder of this Lease, or the application of such term or provision to persons or circumstances or at any time other than those to which it is invalid or unenforceable, shall not be affected thereby, and each term and provision of this Lease shall be valid and shall be enforced to the extent permitted by law.

123

11.7. MERGER, CONSOLIDATION OR SALE OF ASSETS.

11.7.1 A merger or consolidation of Tenant with another unaffiliated entity or the sale of substantially all of the assets of Tenant to another entity shall be subject to the terms of this Section 11.7 and shall require Landlord's reasonable consent. Tenant may, however, without Landlord's consent, merge with or convey its assets to another entity with a credit rating that is equal or better than Tenant's credit rating, as determined by the major national credit rating agencies, including Dunn & Bradstreet, or engage in a leveraged buyout or recapitalization; provided that, if the transaction results in a downgrading of Tenant's credit rating, then Landlord's consent is required. Any of the foregoing acts, if done without the consent of Landlord, if required, shall be void and shall, at the option of Landlord, constitute an Event of Default that entitles Landlord to terminate this Lease unless Tenant makes an offer to purchase the Premises for an amount which is equal to the fair market value of the Premises (including the value of the Lease) determined in the manner set forth in Section 11.3, plus any prepayment costs of the Loan, which such offer may be accepted or rejected by Landlord. If Landlord fails to accept Tenant's purchase offer, it will be deemed to have consented to the merger, consolidation or sale of assets.

11.7.2. In addition to foregoing, if Landlord consents to a merger, consolidation or sale of assets as set forth in Section 11.7.1, or if Tenant has become a subsidiary of a corporation whose senior unsecured and unenhanced debt has an investment grade rating by Standard and Poors Corporation, Tenant shall cause such assignee or parent corporation to deliver to Landlord an unconditional guaranty of payment and performance (and not merely collectability) of all of Tenant's obligations under the Lease, containing customary waivers and in form reasonably satisfactory to Landlord.

11.8. SAVINGS CLAUSE. No provision contained in this Lease which purports to obligate Tenant to pay any amount of interest or any fees, costs or expenses which are in excess of the maximum permitted by applicable law, shall be effective to the extent that it calls for payment of any interest or other sums in excess of such maximum.

11.9. BINDING EFFECT. All of the covenants, conditions and obligations contained in this Lease shall be binding upon and inure to the benefit of the respective successors and assigns of Landlord and Tenant to the same extent as if each successor and assign were in each case named.

11.10. TABLE OF CONTENTS AND HEADINGS. The table of contents and headings used in this Lease are for convenience of reference only and shall not to any extent have the effect of modifying, amending or changing the provisions of this Lease.

Tenant shall have fifteen (15) days after receipt of the First Refusal Notice from Landlord (the "Right of First Refusal Period") to notify Landlord in writing of its intent to purchase the Premises on the terms set forth in the First Refusal Notice. By notifying Landlord within the Right of First Refusal Period, Tenant will be bound under this Lease to purchase the Premises from Landlord, and Landlord will be bound under this Lease to sell to Tenant, the Premises on such terms.

Tenant shall notify Landlord in writing within five (5) days of receipt of the Re-offer Notice whether it elects to purchase the Premises. If Tenant is the purchaser under this Section 11.17, then such purchase shall be on an "as is, where is" basis and Tenant shall release Landlord from any and all claims arising from or related to the condition of the Premises, including without limitation, claims arising under Environmental Laws or Applicable Laws. This right of first refusal shall only apply to the first sale of the Premises to occur after the Commencement Date and shall be extinguished if Tenant fails to accept Landlord's offer to sell the Premises.

IN WITNESS WHEREOF, the parties hereto have executed this Lease as of the day and year first above set forth.

$1,925,000.00 December 24, 1998

1. For value received, the undersigned, TNCA HOLDING LLC, a Delaware limited liability company ("Maker"), promises to pay to the order of TECHNICLONE CORPORATION, a Delaware corporation ("Payee"), the principal sum of One Million Nine Hundred Twenty Five Thousand Dollars ($1,925,000) with interest at the rates set forth below.

On the earlier to occur of December 1, 2010, or the date that fee title to that certain real property legally described in the attached Exhibit "B" is conveyed, assigned, or transferred by TNCA, LLC, a Delaware limited liability company ("Subsidiary"), the outstanding principal balance and any and all accrued interest then due and payable shall be paid in full to Payee by Maker.

3. Notwithstanding the provisions of the first two sentences set forth in paragraph 2 of this Promissory Note ("Note"), in the event that Finova Realty Capital, Inc., a Delaware corporation ("Lender") fails to release funds to Subsidiary pursuant to the terms of the Lock Box Agreement (hereinafter, a "Cash Sweep") in connection with that certain loan of even date herewith ("Loan") by Lender to Subsidiary, solely as a result of Payee's failure to comply with the provisions attached and incorporated hereto as Exhibit "C," then all monthly payments of principal and interest due under this Note shall be suspended during the time the Cash Sweep is in effect. No additional interest will accrue on the principal outstanding balance of the Note during the time Note payments are suspended, however, if Lender pays Subsidiary interest on the cash swept, Maker shall pay to Payee an amount equal to the interest allocable to Note payments otherwise due hereunder. Upon Payee's compliance with the provisions of Exhibit "C" and Lender's resumption of disbursement of funds, Maker shall resume monthly Note payments as set forth in paragraph 2 of this Promissory Note. Upon attainment of the total Tenant Improvement and Leasing Commissions Reserve required by Lender under the provisions of the Lock Box Agreement set forth in Exhibit "C", Maker shall commence making additional monthly payments to Payee of Four Thousand Five Hundred Seventy Eight and no/100 Dollars ($4,578) until such time as the amount of suspended Note payments have been paid in full. The provisions of this paragraph 3 shall not apply, and Note payments shall not be suspended, in the event of a Cash Sweep resulting from Subsidiary's failure to comply with any of the provisions of Exhibit "C".

147

4. Both principal and interest shall be payable to Payee at 14282 Franklin Avenue, Tustin, CA 92780, or at any other place hereafter designated in writing by the holder(s) and delivered to Maker. All sums shall be deemed paid upon receipt of same by the holder(s) hereof.

5. This Promissory Note is secured by that certain Pledge and Security Agreement ("Pledge Agreement") of even date herewith executed by all of the members of Maker.

6. Payments on this Promissory Note shall be applied first to payment of any late charges, second to payment of accrued interest and third to the outstanding principal. If any installment payment on this Promissory Note is not paid within five (5) days of when due, Maker shall pay to the holder hereof an amount equal to six percent (6%) of such overdue installment, plus interest at the rate equal to the Bank of America prime (reference) rate plus two percent (2%) (which amounts are together called the "Late Charge").

7. Maker shall have the right to prepay all or any portion of the indebtedness evidenced by this Promissory Note at any time without premium or penalty.

8. Subject in all events to the provisions of Section 9 hereof, (i) if Maker fails to pay in full any monthly installment of principal and interest or any other sums required to be paid pursuant to this Promissory Note within five (5) days of the due date, or (ii) if any of Maker's members default in the performance or observance of any covenant or condition contained in the Pledge Agreement and such default is not cured within thirty (30) days after receipt of written notice of such default, or (iii) if, pursuant to that certain lease ("Lease") dated as of December ___, 1998 between Subsidiary, as landlord, and Payee, as tenant, with respect to certain real property and improvements located in Tustin, CA, particularly described in the Lease ("Premises"), Payee, or the then tenant under the Lease, is required to purchase the Premises from Subsidiary in accordance with the terms of the Lease, or (iv) if the Lease terminates because of a default on the part of Subsidiary, or (v) if the first trust deed against the Premises is foreclosed upon by the mortgage holder because of a default by Subsidiary, unless such foreclosure is caused by the failure of Payee (or the then tenant under the Lease) to pay any sum due under the Lease, or (vi) if there is a violation of Maker's operating agreement which is materially adverse to Payee, then and in any of such events, the holder of this Promissory Note may, without further notice, immediately declare to be due and payable the entire outstanding indebtedness evidenced by this Promissory Note.

9. Notwithstanding any provisions of this Promissory Note to the contrary, the performance of Maker's obligations pursuant to this Promissory Note are conditioned upon Payee, as tenant under the Lease, timely tendering to Subsidiary all rent, charges and monetary obligations under the Lease ("Lease Payments") as and when the same become due and payable in accordance with the terms of the Lease. In the event that Payee is late in tendering any Lease Payment to Subsidiary, then the applicable due date for Maker's performance of any of Maker's obligations under this Promissory Note shall automatically be extended for the same period of time that Payee was delinquent in the payment of such Lease Payment. Further, in the event that the Lease is terminated pursuant to Section 10 of the Lease due to a default on the part of Payee as tenant thereunder, then, in such event, this Promissory Note shall be deemed to be immediately satisfied in full and Maker shall have no further obligation to Payee hereunder.

148

10. The payment obligations of Maker under this Promissory Note may not be assigned without the consent of Payee, which such consent shall not be unreasonably withheld.

11. Subject to the provisions of Section 9 above, this Promissory Note shall be binding Maker and its successors and assigns.
