             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 THREE MONTHS ENDED JULY 31, 1999 (UNAUDITED)
       -------------------------------------------------------------------------

         1.       SUMMARY OF 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 1999 and during
         the first three months of fiscal 2000 and has an accumulated deficit of
         $95,668,000 at July 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 assurances 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 July 31, 1999, the Company had cash and cash equivalents
         of $1,632,000. During August 1999, the Company exercised its Put option
         and received gross proceeds of $1,250,000 in exchange for 1,718,750
         shares of common stock, including commission shares, pursuant to a
         Regulation D Common Stock Equity Line Subscription Agreement the (the
         "Equity Line Agreement") (Note 2). The Company believes it has
         sufficient cash on hand at August 31, 1999 and available pursuant to
         the Equity Line Agreement (assuming only one future quarterly draw of
         $2,250,000) to meet its obligations on a timely basis through November
         1999. Management believes that additional capital must be raised to
         support the Company's continued operations and other short-term cash
         needs.

                   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 (Note
         2).

       NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
       FOR THE THREE MONTHS ENDED JULY 31, 1999 (UNAUDITED) (CONTINUED)
       -------------------------------------------------------------------------

                    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
         July 31, 1999, and the consolidated results of its operations and its
         consolidated cash flows for the three month periods ended July 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, 1999, filed with the Securities
         and Exchange Commission on July 28, 1999.

                   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.

                   INVENTORIES. Inventories consist of raw materials and
         supplies and are stated at the lower of first-in, first-out cost or
         market.

                   RECLASSIFICATION. Certain reclassifications were made to the
         prior period balances to conform them to the current period
         presentation.

                   NET LOSS PER SHARE. Net loss per share is calculated by
         adding the net loss for the three month period to the Preferred Stock
         dividends and Preferred Stock issuance discount accretion on the Class
         C Preferred Stock during the three month period divided by the weighted
         average number of shares of common stock outstanding during the three
         month period. Shares issuable upon the exercise of common stock
         warrants and options have been excluded from the per share calculation
         for the three month period ended July 31, 1999 and 1998 because their
         effect is antidilutive. Accretion of the Class C Preferred Stock
         dividends and issue discount amounted to $1,000 and $542,000 for the
         quarter ended July 31, 1999 and 1998, respectively.

                  RECENT ACCOUNTING PRONOUNCEMENTS. Effective May 1, 1998, the
         Company adopted SFAS No. 130, Reporting Comprehensive Income, which
         establishes standards for reporting and displaying comprehensive income
         and its components in the consolidated financial statements. For the
         three months ended July 31, 1999 and 1998, the Company did not have any
         components of comprehensive income as defined in SFAS No. 130.

                  The Company adopted 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 stockholders. The adoption of SFAS No. 131 had no impact on the
         Company's consolidated financial statements as the Company operates in
         one industry segment engaged in the research, development and
         commercialization of targeted cancer therapeutics.

                  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 May 1,
         2001. 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 an
         entity to 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.       STOCKHOLDERS' EQUITY

                  During June 1998, the Company secured access to $20,000,000
         under a Common Stock Equity Line ("Equity Line") with two institutional
         investors, expiring in June 2001. Under the terms of the Equity Line,
         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 the share resale limitations
         set forth in Rule 144(e). In addition, if the Company's closing bid
         price falls below $1.00 on any day during the ten trading days prior to
         the Put, the Company's ability to access funds under the Equity Line in
         the Put is limited to 15% of what would otherwise be available. If the
         closing bid price of the Company's common stock falls below $0.50 or if
         the Company is delisted from The Nasdaq SmallCap Market, the Company
         would have no access to funds under the Equity Line.

                  The Equity Line provided for immediate funding of $3,500,000
         in exchange for 2,749,090 shares of common stock, including commission
         shares. One-half of this amount, or $1,750,000, is subject to
         adjustment at three months after the effective date of the registration
         statement registering these shares with the second half subject to
         adjustment six months after such effective date of the registration of
         these shares. 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 actually issued and the amount of shares which
         would have been issued if the purchase price had been the Adjustment
         Price. On July 15, 1999, the Company issued 179,485 shares of common
         stock covering the final six-month adjustment date.

       -------------------------------------------------------------------------

                  Future Puts under the Equity Line are priced at a discount
         equal to the greater of $0.20 or 17.5% off the lowest closing per share
         bid price during the ten trading days immediately preceding the date on
         which such shares are sold to the institutional investors.

                  At the time of each Put, the investors will be issued
         warrants, exercisable only on a cashless basis and expiring on December
         31, 2004, to purchase up to 10% of the amount of common stock issued to
         the investor at the same price as the purchase of the shares sold in
         the Put. During the quarter ended July 31, 1999, the Company issued
         250,948 warrants under the Equity Line at an exercise price ranging
         from $0.61 to $1.24. Also during the quarter ended July 31, 1999, the
         Company issued 6,411 shares of common stock upon the cashless exercise
         of 20,172 Equity Line warrants.

                  In addition, during the quarter ended July 31, 1999, the
         Company received gross proceeds of $2,250,000 in exchange for 2,509,508
         shares of common stock, including commission shares, under the Equity
         Line 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. 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. On June 24, 1999, the first
         anniversary date of the agreement, the Company issued Commitment
         Warrants to purchase up to 17,721 shares of the Company's common stock
         at $1.50 per share, exercisable on a cashless basis only.

         3.       CONTINGENCY

                  On March 18, 1999, the Company was served with notice of a
         lawsuit filed in Orange County Superior Court for the State of
         California by a former employee alleging a single cause of action for
         wrongful termination. The Company believes this lawsuit is barred by a
         severance agreement and release signed by the former employee following
         his termination and the Company is vigorously defending the action. The
         Company's motion for summary judgement is currently pending argument.
         Management does not believe that the outcome of this action will have a
         material adverse effect upon the financial position or results of
         operations of the Company.

         4.       SUBSEQUENT EVENTS

                   On August 4, 1999, the Company entered into a revised license
         agreement with Northwestern University for the licensing of Oncolym(R).
         Under the revised terms, the Company's royalty rate payable to
         Northwestern University was reduced from 6% of net sales to 3% of net
         sales generated in the United States including Guam and Puerto Rico.
         The royalty rate was further reduced to 1.5% of net sales if there is a
         generic form of the licensed product sold in such territory. In
         addition, in all other territories, the royalty rate was reduced to
         1.5% of net sales and further reduced to 1% of net sales if there is a
         generic form of the licensed product sold in such territory. The term
         of the revised license agreement had been reduced from 20 years from
         the first commercial sale to a fixed date ending in February 2009.

    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 1999
    and during the first three months of fiscal 2000 and we have an accumulated
    deficit at July 31, 1999 of $95,668,000. 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 our 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) to meet its
    obligations on a timely basis through November 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. Techniclone Corporation is a biopharmaceutical
    company engaged in the research, development and commercialization of
    targeted cancer therapeutics. We develop product candidates based primarily
    on our proprietary collateral (indirect) tumor targeting technologies for
    the treatment of solid tumors and a direct tumor targeting agent for the
    treatment of refractory malignant lymphoma. We have four potential product
    candidates: two products are in Phase II clinical trials and two products
    are in preclinical studies.

             Collateral (indirect) tumor targeting is the therapeutic strategy
    of targeting peripheral structures and cell types, other than the viable
    cancer cells directly, as a means to treat solid tumors. We are currently
    developing three collateral (indirect) targeting agents for the treatment of
    solid tumors: Tumor Necrosis Therapy, which is potentially capable of
    carrying a variety of therapeutic agents to the interior of solid tumors and
    irradiating the tumor from the inside out; Vasopermeation Enhancement
    Agents, which potentially increases the permeability of the tumor site and
    consequently can increase the concentration of killing agents at the core of
    the tumor; and Vascular Targeting Agents, which potentially creates a
    blockage within the capillaries and blood vessels that supply solid tumors
    with nutrients, thus potentially destroying the tumor.

             A Phase II clinical trial of our Tumor Necrosis Therapy agent
    (called Cotara(TM)) for the treatment of malignant glioma (brain cancer) is
    currently being conducted at The Medical University of South Carolina,
    University of California at Los Angeles, Temple University, University of
    Utah-Salt Lake City and Carolina Neurosurgery & Spine Association, with
    three additional clinical trial sites at various stages of contract
    negotiation. In addition, our Tumor Necrosis Therapy agent is being used in
    an equivalent Phase I clinical trial for the treatment of pancreatic,
    prostrate and liver cancers at a clinical trial site in Mexico City. We are
    collaborating with outside scientists for preclinical studies on
    Vasopermeation Enhancement Agents and on Vascular Targeting Agents.

             On March 8, 1999, we entered into a license agreement with Schering
    A.G., Germany, a major multinational pharmaceutical company, with respect to
    the development, manufacture and marketing of our direct tumor targeting
    agent candidate, Oncolym(R). At the time we entered into the license
    agreement with Schering A.G., Germany, Oncolym(R) was in a Phase II/III
    clinical trial for the treatment of non-Hodgkin's B-cell Lymphoma. Under the
    agreement, Schering A.G., Germany controls the clinical development program
    and funds 80% of the clinical trial costs. Recently, Schering A.G., Germany
    has advised us that they believe the potential success of the Oncolym(R)
    product may be enhanced via a revision of the current Phase II protocol. In
    this context, Schering A.G., Germany is analyzing the results of the current
    Phase II clinical trial and, based on that analysis, may revise the current
    protocol. As such, the current clinical trial sites will remain open for
    treating existing patients, however, no new enrollment of patients will be
    made under the current trial. If a revised protocol is developed by Schering
    A.G., Germany, it will be submitted to the United States Food and Drug
    Administration ("FDA") for additional clinical studies. As part of this
    Oncolym(R) agreement, Schering A.G., Germany and Techniclone are proceeding
    with negotiations concerning the terms of a possible licensing transaction
    on the Vascular Targeting Agents technology. We cannot be certain whether we
    will be successful in entering into a licensing transaction on the Vascular
    Targeting Agents technology on terms satisfactory to us, if at all.

             RESULTS OF OPERATIONS. The Company's net loss of $2,989,000, before
    preferred stock discount accretion and dividends, for the quarter ended July
    31, 1999 represents a decrease in net loss of $317,000 in comparison to the
    net loss of $3,306,000 for the prior year quarter ended July 31, 1998. This
    decrease in the net loss for the quarter ended July 31, 1999 is due to a
    decrease in total costs and expenses of $331,000 offset by a decrease in
    interest and other income of $14,000.

             The Company's total costs and expenses decreased $331,000 during
    the three months ended July 31, 1999 compared to the three months ended July
    31, 1998 due to a decrease in general and administrative expenses of
    $312,000 and a decrease in interest expense of $152,000 offset by an
    increase in research and development expenses of $133,000, in comparison to
    the three months ended July 31, 1998.

             The increase in research and development expenses of $133,000
    during the three months ended July 31, 1999 compared to the same period in
    the prior year is primarily due to increased research fees from MDS Nordion
    associated with the development of a commercial radiolabeling facility. In
    addition, during the quarter ended July 31, 1999, the Company incurred
    increased building lease expense related to the sale and subsequent
    leaseback of the Company's facilities in December 1998 partially offset by a
    corresponding decrease in depreciation expense on the related building. Also
    during the current quarter, the Company incurred increased costs associated
    with the equivalent Phase I study in Mexico City for the treatment of
    pancreatic, liver, and prostate cancers using Cotara(TM). This was offset by
    a decrease in the Oncolym(R) clinical trial fees as Schering A.G., Germany


                                       16


<PAGE>


    is paying for 80% of the clinical trial expenses as defined in the
    agreement. In addition, Schering A.G., Germany is analyzing the results of
    the current Phase II trial and during such time, no new enrollment of
    patients is being made under the current trial, further lowering the
    clinical trial costs for the current quarter.

             The decrease in general and administrative expenses of $312,000
    during the quarter ended July 31, 1999 compared to the quarter ended July
    31, 1998 resulted primarily from a decrease in severance expenses associated
    with the Company's former Chief Executive Officer combined with a decrease
    in consulting fees.

             The decrease in interest expense of $152,000 for the three months
    ended July 31, 1999 compared to the same period in the prior year is
    primarily due to a decrease in interest charges related to construction
    costs incurred in the prior year quarter related to manufacturing facility
    enhancements combined with a decrease in mortgage interest in the current
    quarter as the mortgages were paid in full as part of sale of the facilities
    in December 1998. Such decrease was partially offset by an increase in
    interest charges on a $3,300,000 note payable to Biotechnology Development
    Ltd. related to the buyback of the Oncolym(R) rights in March 1999.

             The decrease in interest and other income of $14,000 during the
    three months ended July 31, 1999 compared to the same period in the prior
    year is primarily due to a decrease in rental income as one of the Company's
    sub-tenants had completed their lease term in March 1999. 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 TNT and
    Oncolym(R) antibodies.

             LIQUIDITY AND CAPITAL RESOURCES. At July 31, 1999, we had
    $1,632,000 in cash and cash equivalents and a working capital deficit of
    $3,387,000. We experienced losses in fiscal 1999 and during the first three
    months of fiscal 2000 and had an accumulated deficit of approximately
    $95,668,000 at July 31, 1999. During August 1999, the Company exercised its
    Put option and received gross proceeds of $1,250,000 in exchange for
    1,718,750 shares of common stock, including commission shares, pursuant to a
    Regulation D Common Stock Equity Line Subscription Agreement the (the
    "Equity Line Agreement"). The Company believes it has sufficient cash on
    hand at August 31, 1999 and available pursuant to the Equity Line Agreement
    (assuming only one future quarterly draw of $2,250,000) to meet its
    obligations on a timely basis through November 1999. Management believes
    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
    preclinical development, clinical trials, 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


                                       17


<PAGE>


    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 clinical trials of Cotara(TM) and the
    equivalent Phase I clinical trials of Cotara(TM) 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.

             COMMITMENTS. At July 31, 1999, we had no material capital
    commitments, although we have 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").

                        OTHER RISK FACTORS OF OUR COMPANY

    IF WE CANNOT OBTAIN ADDITIONAL FUNDING, OUR PRODUCT DEVELOPMENT AND
    COMMERCIALIZATION EFFORTS MAY BE REDUCED OR DISCONTINUED.

             At July 31, 1999, we had $1,632,000 in cash and cash equivalents.
    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 had negative cash flows from operations since inception and expect
    the negative cash flows from operations to continue for the foreseeable
    future. We currently have commitments to expend additional funds for
    antibody and radioactive isotope combination services, clinical trials,
    product development contracts, license contracts, severance arrangements,
    employment agreements, consulting agreements, and for the repurchase of
    marketing rights to certain product technology. We expect operating
    expenditures related to clinical trials to increase in the future as
    clinical trial activity increases and expansion for clinical trial
    production continues. We also expect that the monthly negative cash flows
    will continue. We will require additional funding to sustain our research
    and development efforts, provide for future clinical trials, expand our
    manufacturing and product commercialization capabilities, and continue our
    operations until we are able to generate sufficient revenue from the sale
    and/or licensing of our products.

             During June 1998, we secured access to $20,000,000 under a Common
    Stock Equity Line (Equity Line) with two institutional investors. The Equity
    Line expires in June 2001. Under the terms of the Equity Line, we may, in
    our sole discretion, and subject to certain restrictions, periodically sell
    ("Put") shares of our common stock for up to $20,000,000 upon the effective
    registration of the Put shares. Up to $2,250,000 of Puts, unless an increase
    is otherwise agreed to, can be made every quarter, subject to the
    satisfaction of certain conditions, including share issuance volume
    limitations identical to the share resale limitations set forth in Rule
    144(e). In addition, if the closing bid price of our common stock falls
    below $1.00 during the ten trading days prior to the call date, then the
    amount of Puts will be limited to 15% of what would otherwise be available.
    If the closing bid price of the Company's common stock falls below $0.50 or
    if the Company is delisted from The Nasdaq SmallCap Market, the Company
    would have no access to funds under the Equity Line. As of August 31, 1999,
    we had $10,750,000 available for future Puts under the Equity Line.


                                       18


<PAGE>


             We cannot be certain whether we can obtain 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, these
    new securities may have rights, preferences or privileges senior to the
    presently outstanding securities of the Company. If we are unable to raise
    additional funds when necessary, we may have to reduce or discontinue
    development, commercialization or clinical testing of some or all of our
    product candidates or enter into financing arrangements on terms which we
    would not otherwise accept. 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.

             Without obtaining additional financing or completing a licensing
    transaction, we believe that we have sufficient cash on hand as of August
    31, 1999 and available pursuant to the Equity Line mentioned above, assuming
    we make one additional quarterly draw of $2,250,000, to meet our obligations
    on a timely basis through November, 1999.

    WE HAVE HAD SIGNIFICANT LOSSES AND ANTICIPATE FUTURE LOSSES.

             We have experienced significant losses since inception. As of July
    31, 1999, our accumulated deficit was approximately $95,668,000. 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 expansion
    of manufacturing and product commercialization capabilities. We also expect
    losses to fluctuate substantially from quarter to quarter. All of our
    products are currently in development, preclinical studies or clinical
    trials, and no revenues have been generated from commercial 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
    at least the next year. There can be no guarantee that we will ever generate
    product revenues sufficient to become profitable or to sustain
    profitability.

    PROBLEMS IN PRODUCT DEVELOPMENT MAY CAUSE OUR CASH DEPLETION RATE
    TO INCREASE.

             Our ability to obtain financing and to manage expenses and our cash
    depletion rate is key to the continued development of product candidates and
    the completion of ongoing clinical trials. Our cash depletion rate will vary
    substantially from quarter to quarter as we fund non-recurring items
    associated with clinical trials, product development, antibody manufacturing
    and facility 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 cash depletion
    rate.


                                       19


<PAGE>


    OUR PRODUCT DEVELOPMENT AND COMMERCIALIZATION EFFORTS MAY NOT BE SUCCESSFUL.

             Since inception, we have been engaged in the development of drugs
    and related therapies for the treatment of people with cancer. Our product
    candidates, which have not received regulatory approval, are generally in
    the early stages of development. 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. Our products currently in clinical trials represent a
    departure from more commonly used methods for cancer treatment. These
    products, if approved, may experience under-utilization by doctors who are
    unfamiliar with their application 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 may 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 could also be affected by the availability of third-party
    reimbursement. Accordingly, we cannot guarantee that our product development
    efforts, including clinical trials, or commercialization efforts will be
    successful or that any of our products, if approved, can be successfully
    marketed.


    WE MAY NOT BE ABLE TO EXPAND OUR FACILITIES TO IMPLEMENT COMMERCIAL
    PRODUCTION OF OUR PRODUCTS.

             In order to conduct clinical trials on a timely basis, obtain
    regulatory approval and be commercially successful, we must expand our
    manufacturing and product commercialization processes so that our product
    candidates, if approved, can be manufactured and produced in commercial
    quantities. To date, we have expended significant funds for the expansion of
    our antibody manufacturing capabilities for clinical trial requirements for
    two of our product candidates and for refinement of the production
    processes. We intend to use existing antibody manufacturing capacity to meet
    the clinical trial requirements for these two product candidates and to
    support the initial commercialization of these product candidates, if
    approved. In order to provide additional capacity, we must successfully
    negotiate agreements with contract antibody manufacturers to have these
    products produced, the cost of which is estimated to be several million
    dollars in start-up costs and additional production costs on a "per run
    basis". Such contracts would also require an additional investment estimated
    at five to nine million dollars over the next two years for antibody
    radiolabeling services and related equipment and related production area
    enhancements, and for vendor services associated with technology transfer
    assistance, expansion and production start-up and for regulatory assistance.
    We have limited manufacturing experience, and cannot make any guarantee as
    to our ability to expand 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 or our
    ability to reach an acceptable agreement with one or more contract
    manufacturers to produce any of our other product candidates, if approved,
    in clinical or commercial quantities.

    OUR TECHNOLOGY AND PRODUCTS MAY PROVE INEFFECTIVE OR BE TOO EXPENSIVE TO
    MARKET SUCCESSFULLY.

             Our future success is significantly dependent on our ability to
    develop and test workable products for which we will seek approval from the
    United States Food and Drug Administration 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


                                       20


<PAGE>


    clinical testing and investment over the foreseeable future. Our proposed
    products may not prove to be effective in clinical trials or they may cause
    harmful side effects during clinical trials. In addition, our product
    candidates, if approved, may prove impracticable to manufacture in
    commercial quantities at a reasonable cost and/or with acceptable quality.
    Any of these factors could negatively affect our financial position and
    results of operations.

    OUR DEPENDENCY ON A LIMITED NUMBER OF SUPPLIERS MAY NEGATIVELY IMPACT OUR
    ABILITY TO COMPLETE CLINICAL TRIALS AND MARKET OUR PRODUCTS.

             We currently procure, and intend in the future to procure, our
    antibody radioactive isotope combination services ("radiolabeling") under
    negotiated contracts with two domestic entities, one Canadian entity 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. Prior to commercial distribution of any of our products, if
    approved, we will be required to identify and contract with a commercial
    company for commercial antibody manufacturing and radioactive isotope
    combination services. We are presently in discussions with a few companies
    to provide commercial antibody manufacturing and radioactive isotope
    combination services. We also currently rely on, and expect in the future to
    rely on, our current suppliers for all or a significant portion of the raw
    material requirements for our antibody products. Antibody that has been
    combined with a radioactive isotope cannot be stockpiled against future
    shortages. Accordingly, any change in our existing or future contractual
    relationships with, or an interruption in supply from, any such third-party
    service provider or antibody supplier could negatively impact our ability to
    complete ongoing clinical trials and to market our products, if approved.

    TERMINATION OF OUR RELATIONSHIP WITH SCHERING A.G., GERMANY COULD ADVERSELY
    AFFECT OUR BUSINESS.

             In March 1999, we entered into a license agreement with Schering
    A.G., Germany for the worldwide development, marketing and distribution of
    our direct tumor targeting agent product candidate, Oncolym(R). Under the
    agreement, Schering A.G., Germany has assumed control of the clinical
    development program, regulatory approvals in the United States and all
    foreign countries and handling sales and marketing of this product
    candidate. Schering A.G., Germany may terminate the agreement under a number
    of circumstances as defined in the agreement, including thirty days' written
    notice given at any time prior to receiving regulatory approval. We are
    relying on Schering A.G., Germany to apply its expertise and know-how
    through the development, launch and sale of this product candidate. If
    Schering A.G., Germany decides to discontinue the development of this
    product candidate and terminates our license agreement, we may have to
    discontinue development, commercialization and clinical testing of this
    product candidate, which could negatively affect our operations and
    financial performance. In connection with our agreement with Schering A.G.,
    Germany for Oncolym(R), Schering A.G., Germany has also agreed to discuss
    the development and commercialization of our Vascular Targeting Agent
    technology. If we enter into an agreement with Schering A.G., Germany with
    respect to our Vascular Targeting Agent technology, we will also rely on
    Schering A.G., Germany to apply its expertise and know-how through the
    development, launch and sale of our Vascular Targeting Agent product
    candidates. We cannot guarantee that Schering A.G., Germany will devote the
    resources necessary to successfully develop and/or market any product
    candidate.


                                       21


<PAGE>


    WE DO NOT HAVE A SALES FORCE TO MARKET OUR PRODUCTS.

             At the present time, we do not have a sales force to market any of
    our products, if and when they are approved. We intend to sell our products
    in the United States and internationally in collaboration with one or more
    marketing partners. If and when we receive approval from the United States
    Food and Drug Administration for our initial product candidates, the
    marketing of these products 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 any of our
    product candidates. Other than an agreement with Schering A.G., Germany with
    respect to the marketing of our direct tumor targeting agent product
    candidate, 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 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,
    if and when they are approved.

    WE MAINTAIN ONLY LIMITED PRODUCT LIABILITY INSURANCE AND MAY BE EXPOSED TO
    CLAIMS IF OUR INSURANCE COVERAGE IS INSUFFICIENT.

             The manufacture and sale of human therapeutic products involves an
    inherent risk of product liability claims. We maintain only limited product
    liability insurance. 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.

    EARTHQUAKES MAY DAMAGE OUR FACILITIES.

             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 in or near the greater Southern California area, our
    facilities may sustain significant damage and our operations could be
    negatively affected.

    THE LIQUIDITY OF OUR COMMON STOCK WILL BE ADVERSELY AFFECTED IF OUR COMMON
    STOCK IS DELISTED FROM THE NASDAQ SMALLCAP MARKET.

             The Common Stock is presently traded on The Nasdaq SmallCap Market.
    To maintain inclusion on The Nasdaq SmallCap Market, 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 trading days), at
    least two market makers and at least 300 stockholders, each holding at least


                                       22


<PAGE>


    100 shares of Common Stock. At various times, we have failed to maintain a
    $1.00 minimum closing bid price for extended periods of time and our stock
    may periodically fall below the minimum $1.00 closing bid price for extended
    periods of time in the future. If we fail to meet the minimum closing bid
    price of $1.00 for a period of 30 consecutive trading 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 trading 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 any of 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 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 trading 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. Moreover, should the market price of the Common Stock fall
    significantly, we would be required to issue to the two institutional
    investors a much greater number of shares than we would otherwise if the
    market price were stable or rising, which could cause the market price of
    the Common Stock to fall further and faster. In addition, we and
    broker-dealers effecting transactions in the Common Stock may become subject
    to additional disclosure and reporting requirements applicable to low-priced
    securities, which may reduce the level of trading activity in the secondary
    market for the Common Stock and limit or prevent investors from readily
    selling their shares of Common Stock.

    THE SALE OF SUBSTANTIAL SHARES OF OUR COMMON STOCK MAY DEPRESS OUR STOCK
    PRICE.

             As of August 31, 1999, we had approximately 78,355,000 shares of
    Common Stock outstanding. We are also obligated to issue up to an additional
    approximately 191,000 shares of Common Stock upon conversion of 91
    outstanding shares of our 5% Adjustable Convertible Class C Preferred Stock
    and exercise of related warrants. Under our Regulation D Common Stock Equity
    Line Subscription Agreement with two institutional investors, we may issue
    up to an additional approximately 16,259,000 shares of Common Stock
    (assuming a market price of our common stock of $1.00 per share), at our
    sole option, from time to time, in exchange for an aggregate purchase price
    of $10,750,000, which includes warrants equal to 10% of the shares of Common
    Stock issued under such agreement, which must be exercised on a cashless
    basis only. In addition, an additional approximately 16,050,000 shares of
    Common Stock are issuable upon exercise of outstanding stock options and
    other warrants at an average exercise price of $1.79. The conversion rate
    applicable to our Class C Preferred Stock and the purchase price for the
    shares of Common Stock and warrants to be issued under the Regulation D
    Common Stock Equity Line Subscription Agreement are at a significant
    discount to the market price of the Common Stock. The sale and issuance of
    these shares of Common Stock, as well as subsequent sales of shares of
    Common Stock in the open market, may cause the market price of the Common
    Stock to fall and might impair our ability to raise additional capital
    through sales of equity or equity-related securities, whether under the
    Regulation D Common Stock Equity Line Subscription Agreement or otherwise.

    OUR HIGHLY VOLATILE STOCK PRICE AND TRADING VOLUME MAY ADVERSELY AFFECT THE
    LIQUIDITY OF THE COMMON STOCK.

             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 44,000 shares per day to as many as 19 million shares per day over
    the past eighteen months, and is likely to continue to be highly volatile.
    The market price of the Common Stock may be significantly impacted by many
    factors, including announcements of technological innovations or new
    commercial products by us or our competitors, disputes concerning patent or
    proprietary rights, publicity regarding actual or potential medical results
    relating to products under development by us or our competitors and
    regulatory developments and product safety concerns in both the United
    States and foreign countries. These and other external factors have caused
    and may continue to cause the market price and demand for the Common Stock
    to fluctuate substantially, which may limit or prevent investors from
    readily selling their shares of Common Stock and may otherwise negatively
    affect the liquidity of the Common Stock.

    WE MAY NOT BE ABLE TO COMPETE WITH OUR COMPETITORS IN THE BIOTECHNOLOGY
    INDUSTRY.

             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, as well as 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 direct tumor targeting agent
    product, Oncolym(R). IDEC Pharmaceuticals Corporation is currently marketing
    its lymphoma product for low grade non-Hodgkin's 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
    United States Food and Drug Administration for marketing approval. Coulter
    Pharmaceuticals, Inc. has also announced that it intends to conduct clinical
    trials of its antibody treatment for intermediate and/or high-grade
    non-Hodgkin's lymphomas. 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 with our existing and future competitors or that competition
    will not negatively affect our financial position or results of operations
    in the future.

    WE MAY NOT BE SUCCESSFUL IF WE ARE UNABLE TO OBTAIN AND MAINTAIN 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. Although we
    believe that our patents and our licensors' patents do not infringe on any


                                       24


<PAGE>


    third party's patents, we cannot be certain that we can avoid litigation
    involving such patents or other proprietary rights. Patent and proprietary
    rights litigation entails substantial legal and other costs, and we may not
    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 years to resolve.

    OUR PRODUCT DEVELOPMENT AND COMMERCIALIZATION EFFORTS MAY BE REDUCED OR
    DISCONTINUED DUE TO DIFFICULTIES OR DELAYS IN CLINICAL TRIALS.

             We may encounter unanticipated problems, including development,
    manufacturing, distribution, financing and marketing difficulties, during
    the product development, approval and commercialization process. Our product
    candidates may take longer than anticipated to progress through clinical
    trials or patient enrollment in the clinical trials may be delayed or
    prolonged significantly, thus delaying the clinical trials. Delays in
    patient enrollment will result in increased costs and further delays. If we
    experience any such difficulties or delays, we may have to reduce or
    discontinue development, commercialization or clinical testing of some or
    all of our product candidates. Schering A.G., Germany has recently advised
    us that it is analyzing the results of the current Phase II clinical
    development program for our direct tumor targeting agent product candidate
    and based on that analysis, Schering A.G., Germany may revise the current
    protocol. As such, the current clinical trial sites will remain open for
    treating existing patients, however, no new enrollment of patients will be
    made under the current trial. Schering A.G., Germany has further informed us
    that if a revised protocol is developed, it will be submitted to the United
    States Food and Drug Administration for additional clinical trials. If
    Schering A.G., Germany decides to discontinue the development of this
    product candidate and terminates our license agreement for the worldwide
    development, distribution and marketing of this product candidate, we may
    have to discontinue development, commercialization and clinical testing of
    this product candidate.

    OUR PRODUCT DEVELOPMENT AND COMMERCIALIZATION EFFORTS MAY BE REDUCED OR
    DISCONTINUED DUE TO DELAYS OR FAILURE IN OBTAINING REGULATORY APPROVALS.

             We will need to do substantial additional development and clinical
    testing prior to seeking any regulatory approval for commercialization of
    our product candidates. Testing, manufacturing, commercialization,
    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. 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. Companies in the pharmaceutical and biotechnology industries have
    suffered significant setbacks in conducting advanced human clinical trials,
    even after obtaining promising results in earlier trials. Furthermore, the
    United States Food and Drug Administration 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. Even if
    regulatory approval of a product is granted, such approval may entail
    limitations on the indicated uses for which it may be marketed. Accordingly,
    we may experience difficulties and delays in obtaining necessary
    governmental clearances and approvals to market our products, and we may not
    be able to obtain all necessary governmental clearances and approvals to
    market our products. At least initially, we intend, to the extent possible,
    to rely on licensees to obtain regulatory approval for marketing our
    products. The failure by us or our licensees to adequately demonstrate the
    safety and efficacy of any of our product candidates under development could
    delay, limit or prevent regulatory approval of the product, which may
    require us to reduce or discontinue development, commercialization or
    clinical testing of some or all of our product candidates.

    OUR PRODUCTS, IF APPROVED, MAY NOT BE COMMERCIALLY VIABLE DUE TO HEALTH CARE
    REFORM AND THIRD-PARTY REIMBURSEMENT LIMITATIONS.

             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, price controls on pharmaceuticals and other
    fundamental changes to the health care delivery system. Legislative debate
    is expected to continue in the future, and market forces are expected to
    drive reductions of health care costs. Any such changes could negatively
    impact the commercial viability of our products, if approved. Our ability to
    successfully commercialize our product candidates, if and when they are
    approved, 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. In the absence of national Medicare coverage determination,
    local contractors that administer the Medicare program, within certain
    guidelines, can make their own coverage decisions. Accordingly, there can be
    no assurance that any of our product candidates, if approved and when
    commercially available, will be included within the then, current Medicare
    coverage determination or the coverage determination of state Medicaid
    programs, private insurance companies and other health care providers. In
    addition, third-party payors are increasingly challenging the prices charged
    for medical products and services. The trend toward managed health care and
    the growth of health maintenance organizations in the United States may all
    result in lower prices for our products, if approved and when commercially
    available, than we currently expect. The cost containment measures that
    health care payors and providers are instituting and the effect of any
    health care reform could negatively affect our financial performance, if and
    when one or more of our products are approved and available for commercial
    use.

    OUR MANUFACTURING AND USE OF HAZARDOUS AND RADIOACTIVE MATERIALS MAY RESULT
    IN OUR LIABILITY FOR DAMAGES, INCREASED COSTS AND INTERRUPTION OF ANTIBODY
    SUPPLIES.

             The manufacturing and use of our products 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 combine
    antibodies with radioactive I131 isotope in our products and to comply with
    various local, state, national or international regulations regarding the
    handling and use of radioactive materials. Violation of these regulations by
    these 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. In
    addition, we may incur substantial costs to comply with environmental
    regulations. In the event of any noncompliance or accident, the supply of
    antibodies for use in clinical trials or commercial products could also be
    interrupted.

    OUR OPERATIONS AND FINANCIAL PERFORMANCE COULD BE NEGATIVELY AFFECTED IF WE
    CANNOT ATTRACT AND RETAIN 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, and Dr. John N. Bonfiglio, our
    Vice President of Technology and Business Development and interim 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
    with greater resources. We do not know if we will be successful in
    attracting or retaining skilled personnel. The loss of certain key employees
    or our inability to attract and retain other qualified employees could
    negatively affect our operations and financial performance.

    OUR BUSINESS MAY BE ADVERSELY EFFECTED IF OUR COMPUTER SYSTEMS AND THE
    COMPUTER SYSTEMS OF OUR SUPPLIERS ARE NOT YEAR 2000 COMPLIANT.

             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. The issue is whether computer systems will
    properly recognize date-sensitive information in the year 2000 due to the
    fact that the programming in most computer systems use a two digit year
    value, which value will rollover to "00" as of January 1, 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
    information technology ("IT") and non-IT systems, including major hardware
    and software platforms in use and we have modified and upgraded our
    hardware, software of IT and non-IT systems to be year 2000 compliant. We do
    not presently believe that the year 2000 problem will pose significant
    operational problems for our internal computer systems or have a negative
    effect on our operations. However, we cannot assure you that any year 2000
    compliance problems of our suppliers will not negatively affect our
    operations. 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 any third parties upon which we rely are unable to
    address the year 2000 issue in a timely manner, although we are uncertain as
    to our worst case consequences, it could have an adverse impact on our
    operations, including delaying our clinical trial programs. In order to
    minimize this risk, we have developed a contingency plan, the implementation
    of which should be completed by November 1999, and we intend to devote all
    resources required to attempt to resolve any significant year 2000 problems
    in a timely manner.

    ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
    -------  ----------------------------------------------------------

             A significant change in interest rates would not have a material
    adverse effect on the Company's financial position or results of operations
    due to the amount of cash on hand at July 31, 1999, which consists of
    highly liquid investments, and as the Company's debt instruments have fixed
    interest rates and terms.


                            PART II OTHER INFORMATION


    ITEM 1.  LEGAL PROCEEDINGS.
    -------  ------------------

             On March 18, 1999, the Company was served with notice of a lawsuit
    filed in Orange County Superior Court for the State of California by a
    former employee alleging a single cause of action for wrongful termination.
    The Company believes this lawsuit is barred by a severance agreement and
    release signed by the former employee following his termination and the
    Company is vigorously defending the action. The Company's motion for summary
    judgement is currently pending argument. Management does not believe that
    the outcome of this action will have a material adverse effect upon the
    financial position or results of operations of the Company.

    ITEM 2.  CHANGES IN SECURITIES AND USE OF PROCEEDS.
    -------  ------------------------------------------

             The following is a summary of transactions by the Company during
    the quarterly period commencing on May 1, 1999 and ending on July 31, 1999
    involving issuance and sales of the Company's securities that were not
    registered under the Securities Act of 1933, as amended (the "Securities
    Act").

             On or about June 16, 1999, the Company issued to one unaffiliated
    investor an aggregate of 98,835 shares of the Company's Common Stock upon
    conversion of 30 outstanding shares of the Company's 5% Adjustable
    Convertible Class C Preferred Stock (the "Class C Stock") and upon the
    exercise of outstanding warrants to purchase 47,962 shares of Common Stock
    for total consideration of $31,435. Upon conversion of the 30 shares of
    Class C Stock, the Company issued warrants to such investor to purchase up
    to an aggregate of 12,718 shares of the Company's Common Stock at an
    exercise price of $0.6554 per share, which warrants were exercised and
    included in the total 47,962 warrants.

             On various dates during the quarter ended July 31, 1999, the
    Company issued an aggregate of 2,509,508 shares of the Company's common
    Stock to the two institutional investors and the placement agent under the
    Equity Line, for an aggregate purchase price of $2,250,000, pursuant to an
    Equity Line draw and also issued warrants to the two institutional investors
    and placement agent to purchase up to 250,948 shares of Common Stock, which
    warrants are immediately exercisable on a cashless basis only and expire on
    December 31, 2004.

</TABLE>

             On July 15, 1999, the Company issued an aggregate of 179,485 shares
    of the Company's Common Stock to the two institutional investors and
    placement agent under the Equity Line, for no monetary consideration, as an
    adjustment to the purchase price of one-half of the initial shares sold to
    the two institutional investors in June 1998, pursuant to the terms of the
    Equity Line.

             On various dates during the quarter ended July 31, 1999, the
    Company issued an aggregate of 6,411 shares of the Company's Common Stock to
    one institutional investor upon the cashless exercise of 20,172 warrants
    issued under the Equity Line.

             Under the Equity Line, 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. 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. On June 24, 1999, the first anniversary date of
    the agreement, the Company issued Commitment Warrants to purchase up to
    17,721 shares of the Company's common stock at $1.50 per share, exercisable
    on a cashless basis only.

             The issuances of the securities of the Company in the above
    transactions were deemed to be exempt from registration under the Securities
    Act by virtue of Section 4(2) thereof or Regulation D promulgated
    thereunder, as a transaction by an issuer not involving a public offering.
    The recipient of such securities either received adequate information about
    the Company or had access, through employment or other relationships with
    the Company, to such information.

subject to rights retained by BOARD and ICRT to:


                                       8
<PAGE>


             5.1.1 Publish the general scientific findings from research related
to LICENSED SUBJECT MATTER; provided, that, in order to avoid possible loss of
rights in the PATENT RIGHTS, BOARD hereby agrees to submit any materials
relating to a planned publication to LICENSEE at least sixty (60) days prior to
the date of planned submission for publication. If, within thirty (30) days of
receipt of such materials, LICENSEE notifies BOARD that it desires to file
patent applications pertaining to any inventions contained in such materials,
BOARD shall defer publication or other disclosure for an additional period, not
to exceed ninety (90) days, sufficient to permit such desired patent
applications to be filed.

             5.1.2 Use LICENSED SUBJECT MATTER for research, teaching and other
educationally-related purposes at any institution within the SYSTEM.

         5.2 BOARD hereby also grants to LICENSEE a first option to obtain a
royalty bearing exclusive license to any inventions in the LICENSED FIELD which
arise from work funded by LICENSEE, or previously by PEREGRINE, in which
INVENTORS, singly or jointly, participate while affiliated with UT SOUTHWESTERN
and which have applications in the LICENSED FIELD (collectively,
"IMPROVEMENTS"). The option for any such IMPROVEMENTS shall extend for a period
of ninety (90) days from the date LICENSEE receives written notice from BOARD
disclosing such IMPROVEMENTS. During such ninety (90) day period, BOARD shall
reasonably make available to LICENSEE any other information in its possession or
control which would be useful to LICENSEE in evaluating the IMPROVEMENT, subject
to such reasonable confidentiality undertakings as BOARD shall require. LICENSEE
may exercise its option by informing BOARD in writing during such ninety (90)
day period that it intends to commercialize the IMPROVEMENT as soon as


                                       9
<PAGE>


practicable, consistent with sound and reasonable business practice and
judgment. Upon exercise of LICENSEE's option, such IMPROVEMENT shall become
subject to the terms and conditions of this LICENSE AGREEMENT. In the event that
LICENSEE fails to exercise its option with respect to any IMPROVEMENT as
provided herein, BOARD shall have the right to enter into license agreements
concerning such IMPROVEMENT with third parties provided that the terms and
conditions thereof are not more favorable than those terms and conditions
provided under this LICENSE AGREEMENT unless BOARD has offered the new terms and
conditions to LICENSEE and LICENSEE has refused to accept them.

         5.3 BOARD hereby also grants to LICENSEE a first option to negotiate
and acquire an exclusive, worldwide, royalty-bearing license to any inventions
outside the LICENSED FIELD which arise from work funded by LICENSEE in which
INVENTORS, singly or jointly, participate while affiliated with UT SOUTHWESTERN.
The option for any such inventions shall extend for a period of ninety (90) days
from the date LICENSEE receives written notice from BOARD disclosing such
invention. LICENSEE may exercise its option by informing BOARD in writing during
such ninety (90) day period that it intends to commercialize the invention as
soon as practicable, consistent with sound and reasonable business judgment.
Upon exercise of LICENSEE's option, BOARD and LICENSEE shall enter into good
faith negotiations regarding the terms and conditions of said license and
further agree to negotiate license rates and other payments which are fair and
reasonable to both parties. If BOARD and LICENSEE are unable to agree on the
terms of a license within ninety (90) days following the exercise of LICENSEE's
option, BOARD shall have the right to enter into license agreements concerning
the invention with third parties; provided, however, such licensing agreements
shall be on terms no less favorable to BOARD than BOARD's final offer to
LICENSEE, unless BOARD has offered the new terms and conditions to LICENSEE and
LICENSEE has refused to accept them.

         5.4 LICENSEE shall have the right to extend the license granted herein
to any SUBSIDIARY provided that such SUBSIDIARY consents to be bound by this
LICENSE AGREEMENT to the same extent as LICENSEE.

         5.5 LICENSEE shall have the right to grant sublicenses in accordance
with the terms and conditions of this LICENSE AGREEMENT. LICENSEE agrees to
deliver to BOARD a true and correct copy of each sublicense granted by LICENSEE,
and any modification or termination thereof, within thirty (30) days after
execution, modification, or termination. If any sublicensee fails to pay any
royalty payment to LICENSEE on the date provided in such sublicense, LICENSEE
shall, within thirty (30) days of such scheduled payment date, take steps to
require such sublicensee to cure such default. If such default is not cured by
such sublicensee within an additional ninety (90) day period, LICENSEE shall
terminate such sublicense. If LICENSEE fails to terminate any sublicense as
provided herein, LICENSEE shall be responsible for the payment of royalties owed
by such sublicensee under this LICENSE AGREEMENT whether or not paid to LICENSEE
by such sublicensee. Upon termination of this LICENSE AGREEMENT, any and all
existing sublicenses granted by LICENSEE shall be assigned to BOARD.

         5.6 BOARD shall have the right at any time after five (5) years from
the EFFECTIVE DATE of this LICENSE AGREEMENT, to terminate the exclusivity of
the license granted herein in any national jurisdiction within LICENSED
TERRITORY if LICENSEE, within ninety (90) days after written notice from BOARD
as to such intended termination of exclusivity, fails to provide written
evidence that it has commercialized or is actively attempting to commercialize


                                       11
<PAGE>


an invention licensed hereunder within such jurisdiction. BOARD agrees to
negotiate in good faith with LICENSEE for adjusting terms under such a
non-exclusive arrangement. BOARD shall have the right at any time after seven
(7) years from the EFFECTIVE DATE of this LICENSE AGREEMENT to terminate the
license completely in any national jurisdiction if LICENSEE, within ninety (90)
days after written notice from BOARD of such intended termination, fails to
provide written evidence that it has commercialized or is actively attempting to
commercialize an invention licensed hereunder within such jurisdiction. Evidence
provided by LICENSEE that it has an ongoing and active research, development,
manufacturing, marketing or licensing program as appropriate, directed toward
production and SALE of products based on PATENT RIGHTS, LINKER PATENT RIGHTS,
TECHNOLOGY RIGHTS or LINKER TECHNOLOGY RIGHTS within such jurisdiction shall be
deemed satisfactory evidence.

                                   ARTICLE VI

                              PAYMENTS AND REPORTS

         6.1 Subject to Section 6.1.7 of this LICENSE AGREEMENT, in
consideration of rights granted by BOARD to LICENSEE under this LICENSE
AGREEMENT, LICENSEE agrees to pay BOARD the following:

             6.1.1 A PHASE II TRIAL COMPLETION milestone payment of One Hundred
Thousand Dollars ($100,000) payable within thirty (30) days of the earlier of

                   (a)      February 1, 2001 or

                   (b)      Phase II Trial Completion.


                                       12
<PAGE>


             6.1.2 A milestone payment for COMMERCIAL INTRODUCTION of each
LICENSED PRODUCT in the amount of Three Hundred Thousand Dollars ($300,000)
payable to BOARD within thirty (30) days of COMMERCIAL INTRODUCTION of the
LICENSED PRODUCT. All COMMERCIAL INTRODUCTION milestone payments shall be
credited against royalty payments due under Section 6.1 on a LICENSED
PRODUCT-by-LICENSED PRODUCT basis.

             6.1.3 A running earned royalty equal to four percent (4%) of NET
SALES of LICENSED PRODUCTS incorporating PATENT RIGHTS or LINKER PATENT RIGHTS.
In the event any LICENSED PRODUCT incorporating PATENT RIGHTS or LINKER PATENT
RIGHTS is SOLD as a component of a combination of active elements, NET SALES for
purposes of determining royalty payments on such combination shall be calculated
by multiplying NET SALES of such combination by the fraction A over A+B, in
which "A" is the gross selling price of the LICENSED PRODUCT portion of the
combination when SOLD separately during the accounting period in which the SALE
was made, and "B" is the gross selling price of the non-LICENSED PRODUCT portion
of the combination SOLD separately during the accounting period in question. In
the event that no separate SALE of either such above-designated LICENSED PRODUCT
or such above-designated non-LICENSED PRODUCT portion of the combination is made
during the accounting period in which the SALE was made, NET SALES shall be
calculated by multiplying NET SALES of such combination by the fraction C over
C+D, in which "C" is the standard fully-absorbed cost of the LICENSED PRODUCT
portion of such combination, and "D" is the standard fully absorbed cost of the
other component(s), such costs being arrived at using the standard accounting
procedures of LICENSEE which will be in accord with generally accepted
accounting practices. Notwithstanding the foregoing, under no circumstances
shall the royalty provided for in this Section 6.l.3 be reduced to less than two
percent (2%) of NET SALES of LICENSED PRODUCTS incorporating PATENT RIGHTS or
LINKER PATENT RIGHTS. No royalties shall be payable to BOARD under this Section
6.1.3 with respect to SALES for which a royalty has been paid under the
COAGULATION PATENT LICENSE AGREEMENT.


                                       13
<PAGE>


             6.1.4 A running earned royalty equal to one percent (1 %) of NET
SALES of LICENSED PRODUCTS covered by TECHNOLOGY RIGHTS or LINKER TECHNOLOGY
RIGHTS only. No royalty shall be payable to BOARD under this Section 6.l.4 with
respect to SALES for which a royalty has been paid under Section 6.l.3 or under
the COAGULATION PATENT LICENSE AGREEMENT.

             6.1.5 Twenty percent (20%) of the SUBLICENSEE GROSS REVENUES of
SALES of LICENSED PRODUCTS; provided, however, if a LICENSED PRODUCT is
sublicensed and incorporates technology not covered by PATENT RIGHTS or LINKER
PATENT RIGHTS, the running royalty to be paid under this Section 6.1.5 shall be
reduced to ten percent (10%) of SUBLICENSEE GROSS REVENUES of SALES of LICENSED
PRODUCTS. In the event any LICENSED PRODUCT incorporating PATENT RIGHTS or
LINKER PATENT RIGHTS is sublicensed as a component of a combination of active
elements, SUBLICENSEE GROSS REVENUES of SALES of LICENSED PRODUCTS for purposes
of determining royalty payments on such combination shall be calculated by
multiplying SUBLICENSEE GROSS REVENUES of SALES of LICENSED PRODUCTS of such
combination by the fraction A over A+B, in which "A" is the gross selling price
of the LICENSED PRODUCT portion of the combination when SOLD separately during


                                       14
<PAGE>


the accounting period in which the SALE was made, and "B" is the gross selling
price of the non-LICENSED PRODUCT portion of the combination SOLD separately
during the accounting period in question. In the event that no separate SALE of
either such above-designated LICENSED PRODUCT or such above-designated
non-LICENSED PRODUCT portion of the combination is made during the accounting
period in which the SALE was made, SUBLICENSEE GROSS REVENUES of SALES of
LICENSED PRODUCTS shall be calculated by multiplying SUBLICENSEE GROSS REVENUES
of SALES of LICENSED PRODUCTS of such combination by the fraction C over C+D, in
which "C" is the standard fully-absorbed cost of the LICENSED PRODUCT portion of
such combination, and "D" is the standard fully absorbed cost of the other
component(s), such costs being arrived at using the standard accounting
procedures of LICENSEE which will be in accord with generally accepted
accounting practices. Notwithstanding the foregoing, under no circumstances
shall the royalty provided for in this Section 6.1.5 be reduced to less than ten
percent (10%) of SUBLICENSEE GROSS REVENUES of SALES of LICENSED PRODUCTS
incorporating PATENT RIGHTS or LINKER PATENT RIGHTS. No royalties shall be
payable to BOARD under this Section 6.1.5 with respect to SALES for which a
royalty has been paid under the COAGULATION PATENT LICENSE AGREEMENT.

             6.1.6 The parties hereto agree that if economic or political
conditions change sufficiently so as to affect the continued applicability of
the assumptions made in negotiating the dates of the milestone payments agreed
to in Section 6.1, they will negotiate in good faith a reasonable extension of
the dates of such milestone payments in accordance with such changed economic or
political conditions.

             6.1.7 Notwithstanding anything to the contrary in this LICENSE
AGREEMENT, it is hereby acknowledged and agreed by the parties hereto that (i)
the amount payable by LICENSEE pursuant to Section 6.1.1 of this LICENSE
AGREEMENT is a one-time license fee payable by LICENSEE only with respect to the
first LICENSED PRODUCT of LICENSEE and (ii) no amounts shall be paid by LICENSEE
pursuant to such Sections to the extent that such payments have been made by
LICENSEE under the COAGULATION PATENT LICENSE AGREEMENT.

         6.2 During the term of this LICENSE AGREEMENT and for one (1) year
thereafter, LICENSEE shall keep complete and accurate records of its SALES and
NET SALES of LICENSED PRODUCTS and all SUBLICENSEE GROSS REVENUES received by
LICENSEE under the license granted in this LICENSE AGREEMENT in sufficient
detail to enable the royalties payable hereunder to be determined. LICENSEE
shall permit BOARD or its representatives, at BOARD's expense, to periodically
examine its books, ledgers, and records during regular business hours for the
purposes of and to the extent necessary to verify any report required under this
LICENSE AGREEMENT. If any such inspection reveals that the aggregate of
royalties paid during any four (4) consecutive calendar quarters was less than
the amount that should have been paid under this LICENSE AGREEMENT, LICENSEE
shall remit to BOARD the amount of such deficiency; provided, that, if such
deficiency is more than five percent (5%) of the amount that should have been
paid, LICENSEE shall remit to BOARD, in addition to the amount of such
deficiency, the reasonable expenses of the inspection conducted by BOARD. If
LICENSEE or BOARD disputes any deficiency or expenses provided in this Section
6.2 the dispute shall be referred to an independent accountant selected by
mutual agreement of BOARD and LICENSEE, whose decision will be binding and final
on the parties hereto. If a decision is entered against LICENSEE by such
independent accountant for the amount of such deficiency or expenses, LICENSEE
agrees to remit to BOARD, in addition to any other amounts provided for in this
Section 6.2, accrued interest on such deficiency through the date of such
decision at the highest allowable rate.

         6.3 Within forty-five (45) days after March 31, June 30, September 30,
and December 31 of each year, LICENSEE shall deliver to BOARD a true and
accurate report which shall describe (a) the quantities of LICENSED SUBJECT
MATTER that it has produced; (b) the total SALES; (c) the calculation of
royalties thereon; and (d) the total royalties so computed and due.
Simultaneously with the delivery of each such report, LICENSEE shall pay to
BOARD the amount, if any, due for the period covered by such report. If no
payments are due, it shall be so reported.

         6.4 Upon the request of BOARD but not more often than once per calendar
year, LICENSEE shall deliver to BOARD a written report as to LICENSEE's efforts
and accomplishments during the preceding year in commercializing LICENSED
SUBJECT MATTER in various parts of the LICENSED TERRITORY and its
commercialization plans for the upcoming year.

                              TERM AND TERMINATION

         7.1 The Term of this LICENSE AGREEMENT shall extend from the EFFECTIVE
DATE set forth hereinabove to the full end of the term or terms for which PATENT
RIGHTS or LINKER PATENT RIGHTS have not expired or if only TECHNOLOGY RIGHTS or
LINKER TECHNOLOGY RIGHTS are licensed and no PATENT RIGHTS or LINKER PATENT
RIGHTS are applicable, then, on a per-product basis, (i) with respect to
LICENSED PRODUCTS which have an FDA-approved therapeutic indication for humans,
for a term of seven (7) years from the date of COMMERCIAL INTRODUCTION of any
such product and (ii) with respect to LICENSED PRODUCTS which have an
FDA-approved diagnostic indication for humans, for a term of seven (7) years
from the date of COMMERCIAL INTRODUCTION of such product.

         7.2 This LICENSE AGREEMENT will earlier terminate:

             7.2.1 upon thirty (30) days written notice if LICENSEE shall
default in its obligation to make payments, if any are due, in accordance with
Article VI or Article XIV hereunder; provided, however, LICENSEE may avoid such
termination if before the end of such notice period LICENSEE cures its default;


                                       18
<PAGE>


             7.2.2 automatically if LICENSEE shall become bankrupt or insolvent
and/or if the business of LICENSEE shall be placed in the hands of a receiver,
assignee, or trustee, whether by voluntary act or LICENSEE or otherwise;

             7.2.3 upon ninety (90) days written notice if LICENSEE shall breach
or default on any obligation under this LICENSE AGREEMENT except as provided in
Article VI or Article XIV; provided, however, LICENSEE may avoid such
termination if before the end of such period LICENSEE notifies BOARD that such
breach has been cured, states the manner of such cure and in fact the breach has
been cured; or

             7.2.4 Under the provisions of Section 5.6 if invoked.

         7.3 Upon termination of this LICENSE AGREEMENT for any cause, nothing
herein shall be construed to release either party of any obligation matured
prior to the effective date of such termination. LICENSEE may, after the
effective date of such termination, SELL all LICENSED PRODUCT and parts therefor
that it may have on hand at the date of termination, provided that it pays
running royalty earned thereon as provided in this LICENSE AGREEMENT.

                                  ARTICLE VIII

                          INFRINGEMENT BY THIRD PARTIES

         8.1 Each party shall inform the other promptly in writing of any
alleged infringement of the PATENT RIGHTS or LINKER PATENT RIGHTS by a third
party, including all details then available. LICENSEE shall have the right, but
shall not be obligated, to prosecute at its own expense any such infringements,
and BOARD agrees that LICENSEE may join BOARD as a plaintiff at the expense of
LICENSEE. In any infringement action commenced or defended solely by LICENSEE,
all expenses and all recovery for infringement shall be those of LICENSEE. In
any such action by LICENSEE, BOARD shall be entitled to receive an amount equal
to the applicable royalties on any recovery of profits and damages that is in
excess of LICENSEE's reasonable costs and expenses, including, but not limited
to actual costs and expenses paid non-affiliated accountants, lawyers and
consultants. No settlement, consent judgment or other voluntary final
disposition of the suit may be entered into without BOARD's consent, which
consent shall not be unreasonably withheld, delayed or conditioned.

         8.2 If LICENSEE has not commenced legal action or been successful in
obtaining cessation of the infringement within ninety (90) days of written
notification from BOARD of such infringement, or if LICENSEE elects not to
continue prosecuting any legal action against an infringer, BOARD shall have the
right, but shall not be obligated, to prosecute at its own expense any such
infringement. BOARD may join LICENSEE as a plaintiff in any such infringement
suit at BOARD's expense. No settlement, consent judgment or other voluntary
final disposition of the suit may be entered into without LICENSEE's consent,
which consent shall not be unreasonably withheld, delayed or conditioned.


                                       20
<PAGE>


         8.3 In the event that LICENSEE and/or BOARD do not file suit against,
conclude settlement negotiations with, or grant a license to a substantial
infringer of PATENT RIGHTS or LINKER PATENT RIGHTS within one (1) year of
knowledge thereof, then the parties will consult with one another in an effort
to determine whether a reasonably prudent licensee would institute litigation,
conclude settlement negotiations, and/or grant a license within the one (1) year
time period described above in order to enforce the patent in question in light
of all relevant business and economic factors (including, but not limited to,
the projected cost of such litigation, the likelihood of success on the merits,
the probable amount of any damage award, the prospects for satisfaction of any
judgment against the alleged infringer, the possibility of counterclaims against
LICENSEE and BOARD, the diversion of LICENSEE's human and economic resources,
the impact of any possible adverse outcome on LICENSEE, and the effect any
publicity might have on the respective reputations and goodwill of the parties).
If after such consultation, the parties have not reached agreement and LICENSEE
does not forthwith file suit against, enter into settlement negotiations with or
grant a license to the substantial infringer, then BOARD shall have the right to
enforce any PATENT RIGHT or LINKER PATENT RIGHT, licensed hereunder on behalf of
itself and LICENSEE (BOARD retaining all recoveries from such enforcement), and
BOARD shall have the right to reduce the license granted hereunder to
nonexclusive in the national jurisdiction in which suit is brought.

         8.4 In any infringement suit that either party brings to enforce the
PATENT RIGHTS or LINKER PATENT RIGHTS, the other party shall at the request and
expense of the party bringing the suit, cooperate in all reasonable respects,
including, to the extent possible, obtaining the testimony of its employees and
agents and making available physical evidence in the possession of that party.

         This LICENSE AGREEMENT shall not be assignable or otherwise
transferable by LICENSEE without the prior written consent of BOARD, which
consent shall not be unreasonably withheld, except that LICENSEE may assign or
otherwise transfer its rights under this LICENSE AGREEMENT to the following
parties without obtaining BOARD's consent: (i) a successor to LICENSEE's
business, or a successor to that portion of LICENSEE's business that pertains to
the subject matter of the PATENT RIGHTS or LINKER PATENT RIGHTS or any
TECHNOLOGY RIGHTS or LINKER TECHNOLOGY RIGHTS, and (ii) any entities controlled

         LICENSEE shall hold harmless and indemnify BOARD, INVENTORS, SYSTEM, UT
SOUTHWESTERN, ICRT, and their respective Regents, officers, employees and agents
(each, an "INDEMNITEE") from and against any liability, loss or damage they may
suffer as a result of claims, demands, or causes of action whatsoever, including
without limitation those arising on account of any injury or death of persons or
damage to property caused by, or arising out of or resulting from, the exercise
or practice of the license granted hereunder by LICENSEE or its officers,
employees, agents or representatives; provided, however, that LICENSEE shall not
be required to indemnify or hold harmless any INDEMNITEE, from any losses or
claims attributable to any infringement or alleged infringement of patents,
technology, trade secrets, or confidential or proprietary know-how or
information of third parties by the PATENT RIGHTS or LINKER PATENT RIGHTS or the
TECHNOLOGY RIGHTS or LINKER TECHNOLOGY RIGHTS. Except as otherwise provided in
this LICENSE AGREEMENT, the obligations of LICENSEE under this Section shall
apply in full force whether or not the claims and any losses resulted, or are
alleged to have resulted, in whole or in part from the acts or omissions of any
INDEMNITEE; PROVIDED, HOWEVER, that the foregoing indemnity shall not apply to
any claims or losses arising out of any act or omission constituting gross
negligence, willful malfeasance, misconduct or bad faith of any INDEMNITEE.

         LICENSEE shall not use the name of UT SOUTHWESTERN, INVENTORS, SYSTEM,
BOARD, ICRT or their respective Regents in any advertising, promotional or sales
literature, or in any other form of publicity without prior written consent
obtained from each such party in each case. The foregoing notwithstanding,
LICENSEE shall have the right to identify such parties and to disclose the terms
of this LICENSE AGREEMENT in any prospectus, offering memorandum or other
document or filing required by applicable securities laws or other applicable
law or regulation, provided that LICENSEE shall have given each such affected
party at least ten (10) business days prior written notice of the proposed text
of any such identification or disclosure for the purpose of giving each such
affected party the opportunity to comment on and suggest amendments to such
proposed text.

                                  ARTICLE XIII

                            CONFIDENTIAL INFORMATION

         13.1 BOARD and LICENSEE each agree that all information contained in
documents marked "confidential" which are forwarded to one by the other shall be
received in strict confidence, used only for the purposes of this LICENSE
AGREEMENT, and not disclosed by the recipient party (except as required by law
or court order), its agents or employees without the prior written consent of
the other party, unless such information (a) was in the public domain at the
time of disclosure, (b) later became part of the public domain through no act or
omission of the recipient party, its employees, agents, successors or assigns,
(c) was lawfully disclosed to the recipient party by a third party having the
right to disclose it, (d) was already known by the recipient party at the time
of disclosure, (e) was independently developed or (f) is required by law or
regulation to be disclosed.

         13.2 Each party's obligation of confidence hereunder shall be fulfilled
by using at least the same degree of care with the other party's confidential
information as it uses to protect its own confidential information. This
obligation shall exist while this LICENSE AGREEMENT is in force and for a period
of three (3) years thereafter.

                                   ARTICLE XIV

                              PATENT AND INVENTIONS

         14.1 UT SOUTHWESTERN shall be responsible for the preparation, filing,
prosecution and maintenance of all patent applications and patents included in
PATENT RIGHTS and LINKER PATENT RIGHTS. LICENSEE shall reimburse UT SOUTHWESTERN
for all reasonable attorneys' fees (i) incurred by UT SOUTHWESTERN subsequent to
the EFFECTIVE DATE, or (ii) incurred by UT SOUTHWESTERN prior to the EFFECTIVE
DATE and for which invoices have been submitted to LICENSEE in connection with
the preparation, filing and maintenance of all patent applications and patents
included in PATENT RIGHTS and LINKER PATENT RIGHTS; provided that patent counsel
selected by UT SOUTHWESTERN is reasonably acceptable to LICENSEE. Subsequent to
the EFFECTIVE DATE, UT SOUTHWESTERN shall consult with LICENSEE as to the
preparation, filing, prosecution and maintenance of all such patent applications
and patents in accordance with the procedures set forth on Exhibit B hereto and
incorporated herein by reference, and shall furnish to LICENSEE copies of
documents relevant to such preparation, filing, prosecution or maintenance,
including without limitation invoices providing detailed descriptions of all


                                       25
<PAGE>


costs and expenses incurred by UT SOUTHWESTERN's patent counsel in connection
therewith, sufficiently prior to filing such documents or making any payment due
thereunder to allow for review and comment by LICENSEE. If, at any time,
LICENSEE shall elect not to pay the expenses of any patent application or patent
included in PATENT RIGHTS or LINKER PATENT RIGHTS, LICENSEE shall so notify UT
SOUTHWESTERN within thirty (30) days of such consultation and shall thereby
surrender its rights under such patent application or patent; provided, however,
that LICENSEE shall remain obligated to reimburse UT SOUTHWESTERN for any costs
incurred with respect to such patent application or patents prior to said
election.

         14.2 At any time during the term of this LICENSE AGREEMENT, LICENSEE
may petition BOARD in writing to transfer prosecution or maintenance of any
PATENT RIGHTS licensed hereunder to another law firm. Such petition shall state
LICENSEE's reason(s) for its desire to transfer prosecution or maintenance to
another law firm and include information about the law firm and individual
patent attorneys, patent agents, and/or scientific advisors that may be assigned
to the files by the patent firm. BOARD shall first seek to meet the needs of
LICENSEE through meeting with existing patent counsel. If the petition is
granted by BOARD, LICENSEE or outside counsel shall provide BOARD and UT
SOUTHWESTERN with copies of all documents received or filed during prosecution
and/or maintenance thereof in a timely manner. In any event, LICENSEE shall
consult UT SOUTHWESTERN prior to abandonment of any claims of any patent
application for LICENSED SUBJECT MATTER at least sixty (60) days prior to
abandonment.

                                       6
<PAGE>


             (a) Publish the general scientific findings from research
         related to LICENSED SUBJECT MATTER; PROVIDED, that, in order to avoid
         possible loss of rights in the COAGULATION PATENT RIGHTS, BOARD hereby
         agrees to submit any materials relating to a planned publication to
         LICENSEE at least sixty (60) days prior to the date of planned
         submission for publication. If, within thirty (30) days of receipt of
         such materials, LICENSEE notifies BOARD that it desires to file patent
         applications pertaining to any inventions contained in such materials,
         BOARD shall defer publication or other disclosure for an additional
         period, not to exceed ninety (90) days, sufficient to permit such
         desired patent applications to be filed.

             (b) Use LICENSED SUBJECT MATTER for research, teaching and
         other educationally-related purposes at any institution within the
         SYSTEM.

         5.2 BOARD hereby also grants to LICENSEE a first option to obtain a
royalty-bearing exclusive license to any inventions in the LICENSED FIELD which
arise from work funded by LICENSEE in which INVENTORS, singly or jointly
participate while affiliated with UT SOUTHWESTERN and which have applications in
the LICENSED FIELD (collectively, "IMPROVEMENTS"). The option for any such
IMPROVEMENTS shall extend for a period of ninety (90) days from the date
LICENSEE receives a written notice from BOARD disclosing such IMPROVEMENTS.
During such ninety (90) day period, BOARD shall reasonably make available to
LICENSEE any other information in its possession or control which would be
useful to LICENSEE in evaluating the IMPROVEMENT, subject to such reasonable
confidentiality undertakings as BOARD shall require. LICENSEE may exercise its
option by informing BOARD in writing during such ninety (90) day period that it
intends to commercialize the IMPROVEMENT as soon as practicable, consistent with
sound and reasonable business practice and judgment. Upon exercise of LICENSEE's


                                       7
<PAGE>


option, such IMPROVEMENT shall become subject to the terms and conditions of
this AGREEMENT. In the event that LICENSEE fails to exercise its option with
respect to any IMPROVEMENT as provided herein, BOARD shall have the right to
enter into license agreements concerning such IMPROVEMENT with third parties
provided the terms and conditions thereof are not, in general, more favorable
than those terms and conditions provided under this AGREEMENT, unless BOARD has
offered the new terms and conditions to LICENSEE and LICENSEE has refused to
accept them.

         5.3 BOARD hereby also grants to LICENSEE a first option to negotiate
and acquire an exclusive, worldwide, royalty-bearing license to any inventions
outside the LICENSED FIELD which arise from work funded by LICENSEE in which
INVENTORS, singly or jointly, participate while affiliated with UT SOUTHWESTERN.
The option for any such inventions shall extend for a period of ninety (90) days
from the date LICENSEE receives written notice from BOARD disclosing such
invention. LICENSEE may exercise its option by informing BOARD in writing during
such ninety (90) day period that it intends to commercialize the invention as
soon as practicable, consistent with sound and reasonable business judgment.
Upon exercise of LICENSEE's option, BOARD and LICENSEE shall enter into good
faith negotiations regarding the terms and conditions of said license and
further agree to negotiate license rates and other payments which are fair and
reasonable to both parties. If BOARD and LICENSEE are unable to agree on the
terms of a license within ninety (90) days following the exercise of LICENSEE'S
option, BOARD shall have the right to enter into license agreements concerning
the invention with third parties; PROVIDED, HOWEVER, such licensing agreements
shall be on terms no less favorable to BOARD than BOARD's final offer to
LICENSEE, unless BOARD has offered the new terms and conditions to LICENSEE and
LICENSEE has refused to accept them.

         5.4 LICENSEE shall have the right to extend the license granted herein
to any SUBSIDIARY provided that such SUBSIDIARY consents to be bound by this
AGREEMENT to the same extent as LICENSEE.

         5.5 LICENSEE shall have the right to grant sublicenses in accordance
with the terms and conditions of this AGREEMENT. LICENSEE agrees to deliver to
BOARD a true and correct copy of such sublicense granted by LICENSEE, and any
modification or termination thereof, within thirty (30) days after execution,
modification, or termination. If any sublicense fails to pay any royalty payment
to LICENSEE on the date provided in such sublicense, LICENSEE shall, within
thirty (30) days of such scheduled payment date, take steps to require such
sublicensee to cure such default. If such default is not cured by such
sublicensee within an additional ninety (90) day period, LICENSEE shall
terminate such sublicense. If LICENSEE fails to terminate any sublicense as
provided herein, LICENSEE shall be responsible for the payment of royalties owed
by such sublicensee under this AGREEMENT whether or not paid to LICENSEE by such
sublicensee. Upon termination of this AGREEMENT, any and all existing
sublicenses granted by LICENSEE shall be assigned to BOARD.

         5.6 BOARD shall have the right at any time after five (5) years from
the EFFECTIVE DATE of this AGREEMENT, to terminate the exclusivity of the
license granted herein in any national jurisdiction within LICENSED TERRITORY if
LICENSEE, within ninety (90) days after written notice from BOARD as to such
intended termination of exclusivity, fails to provide written evidence that it
has commercialized or is actively attempting to commercialize an invention
licensed hereunder within such jurisdiction. BOARD agrees to negotiate in good
faith with LICENSEE for adjusting terms under such a non-exclusive arrangement.
BOARD shall have the right at any time after seven (7) years from the EFFECTIVE


                                       9
<PAGE>


DATE of this AGREEMENT to terminate the license completely in any national
jurisdiction if LICENSEE, within ninety (90) days after written notice from
BOARD of such intended termination, fails to provide written evidence that it
has commercialized or is actively attempting to commercialize an invention
licensed hereunder within such jurisdiction. Evidence provided by LICENSEE that
it has an ongoing and active research, development, manufacturing, marketing or
licensing program as appropriate, directed toward production and SALE of
products based on COAGULATION PATENT RIGHTS or COAGULATION TECHNOLOGY RIGHTS
within such jurisdiction shall be deemed satisfactory evidence.

                            VI. PAYMENTS AND REPORTS
                                --------------------

         6.1 Subject to Section 6.1(g) of this AGREEMENT, in consideration of
rights granted by BOARD to LICENSEE under this AGREEMENT, LICENSEE agrees to pay
BOARD the following:

                  (a) A PHASE II TRIAL COMPLETION milestone payment of one
         hundred thousand dollars ($100,000) payable within thirty (30) days of
         the earlier of: (i) February 1, 2001, or (ii) PHASE II TRIAL
         COMPLETION.

                  (b) A milestone payment for COMMERCIAL INTRODUCTION of each
         LICENSED PRODUCT in the amount of three hundred thousand dollars
         ($300,000) payable to BOARD within thirty (30) days of COMMERCIAL
         INTRODUCTION of the LICENSED PRODUCT. All COMMERCIAL INTRODUCTION
         milestone payments shall be credited against royalty payments due under
         Section 6.1 on a LICENSED PRODUCT-by-LICENSED PRODUCT basis.


                                       10
<PAGE>


                  (c) A running earned royalty equal to four percent (4%) of NET
         SALES of LICENSED PRODUCTS incorporating COAGULATION PATENT RIGHTS. In
         the event any LICENSED PRODUCT incorporating COAGULATION PATENT RIGHTS
         is SOLD as a component of a combination of active elements, NET SALES
         for purposes of determining royalty payments on such combination shall
         be calculated by multiplying NET SALES of such combination by the
         fraction A over A+B, in which "A" is the gross selling price of the
         LICENSED PRODUCT portion of the combination when SOLD separately during
         the accounting period in which the SALE was made, and "B" is the gross
         selling price of the non-LICENSED PRODUCT portion of the combination
         SOLD separately during the accounting period in question. In the event
         that no separate SALE of either such above-designated LICENSED PRODUCT
         or such above-designated non-LICENSED PRODUCT portion of the
         combination is made during the accounting period in which the SALE was
         made, NET SALES shall be calculated by multiplying NET SALES of such
         combination by the fraction C over C+D, in which "C" is the standard
         fully-absorbed cost of the LICENSED PRODUCT portion of such
         combination, and "D" is the standard fully absorbed cost of the other
         component(s), such costs being arrived at using the standard accounting
         procedures of LICENSEE which will be in accord with generally accepted
         accounting practices. Notwithstanding the foregoing, under no
         circumstances shall the royalty provided for in this Section 6.1(c) be
         reduced to less than two percent (2%) of NET SALES of LICENSED PRODUCTS
         incorporating COAGULATION PATENT RIGHTS. No royalties shall be payable
         to BOARD under this Section 6.1(c) with respect to SALES for which a
         royalty has been paid under the PATENT LICENSE AGREEMENT.


                                       11
<PAGE>


                  (d) A running earned royalty equal to one percent (1%) of NET
         SALES of LICENSED PRODUCTS covered by COAGULATION TECHNOLOGY RIGHTS
         only. No royalty shall be payable to BOARD under this Section 6.1(d)
         with respect to SALES for which a royalty is has been paid under
         Section 6.1(c) or under the PATENT LICENSE AGREEMENT.

                  (e) Twenty percent (20%) of the SUBLICENSEE GROSS REVENUES of
         SALES of LICENSED PRODUCTS; provided, however, if a LICENSED PRODUCT is
         sublicensed and incorporates technology not covered by COAGULATION
         PATENT RIGHTS, the running royalty to be paid under this Section 6.1(e)
         shall be reduced to ten percent (10%) of SUBLICENSEE GROSS REVENUES of
         SALES of LICENSED PRODUCTS. In the event any LICENSED PRODUCT
         incorporating COAGULATION PATENT RIGHTS is sublicensed as a component
         of a combination of active elements, SUBLICENSEE GROSS REVENUES of
         SALES of LICENSED PRODUCTS for purposes of determining royalty payments
         on such combination shall be calculated by multiplying SUBLICENSEE
         GROSS REVENUES of SALES of LICENSED PRODUCTS of such combination by the
         fraction A over A+B, in which "A" is the gross selling price of the
         LICENSED PRODUCT portion of the combination when SOLD separately during
         the accounting period in which the SALE was made, and "B" is the gross
         selling price of the non-LICENSED PRODUCT portion of the combination
         SOLD separately during the accounting period in question. In the event
         that no separate SALE of either such above-designated LICENSED PRODUCT
         or such above-designated non-LICENSED PRODUCT portion of the
         combination is made during the accounting period in which the SALE was
         made, SUBLICENSEE GROSS REVENUES of SALES of LICENSED PRODUCTS shall be
         calculated by multiplying SUBLICENSEE GROSS REVENUES of SALES of
         LICENSED PRODUCTS of such combination by the fraction C over C+D, in
         which "C" is the standard fully-absorbed cost of the LICENSED PRODUCT


                                       12
<PAGE>


         portion of such combination, and "D" is the standard fully absorbed
         cost of the other component(s), such costs being arrived at using the
         standard accounting procedures of LICENSEE which will be in accord with
         generally accepted accounting practices. Notwithstanding the foregoing,
         under no circumstances shall the royalty provided for in this Section
         6.1(e) be reduced to less than ten percent (10%) of SUBLICENSEE GROSS
         REVENUES of SALES of LICENSED PRODUCTS incorporating COAGULATION PATENT
         RIGHTS. No royalties shall be payable to BOARD under this Section
         6.1(e) with respect to SALES for which a royalty has been paid under
         the PATENT LICENSE AGREEMENT.

                  (f) The parties hereto agree that if economic or political
         conditions change sufficiently so as to affect the continued
         applicability of the assumptions made in negotiating the dates of the
         milestone payments agreed to in this Section 6.1, they will negotiate
         in good faith a reasonable extension of the dates of such milestone
         payments in accordance with such changed economic or political
         conditions.

                  (g) Notwithstanding anything to the contrary in this
         AGREEMENT, it is hereby acknowledged and agreed by the parties hereto
         that (i) the amount payable by LICENSEE pursuant to Section 6.1(a) of
         this AGREEMENT is a one-time license fee payable by LICENSEE only with
         respect to the first LICENSED PRODUCT of LICENSEE and (ii) no amounts
         shall be paid by LICENSEE pursuant to such Sections to the extent that
         such payments have been made by LICENSEE under the PATENT LICENSE
         AGREEMENT.

         6.2 During the term of this AGREEMENT and for one (1) year thereafter,
LICENSEE shall keep complete and accurate records of its SALES and NET SALES of
LICENSED PRODUCTS and all SUBLICENSEE GROSS REVENUES received by LICENSEE under
the license granted in this AGREEMENT in sufficient detail to enable the
royalties payable hereunder to be determined. LICENSEE shall permit BOARD or its


                                       13
<PAGE>


representatives, at BOARD's expense, to periodically examine its books, ledgers,
and records during regular business hours for the purposes of and to the extent
necessary to verify any report required under this AGREEMENT. If any such
inspection reveals that the aggregate of royalties paid during any four (4)
consecutive calendar quarters was less than the amount that should have been
paid under this AGREEMENT, LICENSEE shall remit to BOARD the amount of such
deficiency; provided, that, if such deficiency is more than five percent (5%) of
the amount that should have been paid, LICENSEE shall remit to BOARD, in
addition to the amount of such deficiency, the reasonable expenses of the
inspection conducted by BOARD. If LICENSEE or BOARD disputes any deficiency or
expenses provided in this Section 6.2, the dispute shall be referred to an
independent accountant selected by mutual agreement of BOARD and LICENSEE, whose
decision will be binding and final on the parties hereto. If a decision is
entered against LICENSEE by such independent accountant for the amount of such
deficiency or expenses, LICENSEE agrees to remit to BOARD, in addition to any
other amounts provided for in this Section 6.2, accrued interest on such
deficiency through the date of such decision at the highest allowable rate.

         6.3 Within forty-five (45) days after March 31, June 30, September 30
and December 31 of each year, LICENSEE shall deliver to BOARD a true and
accurate report which shall describe (a) the quantities of LICENSED SUBJECT
MATTER that it has produced; (b) the total SALES; (c) the calculation of
royalties thereon; and (d) the total royalties so computed and due.
Simultaneously with the delivery of each such report, LICENSEE shall pay to
BOARD the amount, if any, due for the period covered by such report. If no
payments are due, it shall be so reported.


                                       14
<PAGE>


         6.4 Upon the request of BOARD but not more often than once per calendar
year, LICENSEE shall deliver to BOARD a written report as to LICENSEE's efforts
and accomplishments during the preceding year in commercializing LICENSED
SUBJECT MATTER in various parts of the LICENSED TERRITORY and its
commercialization plans for the upcoming year.

         6.5 All amounts payable hereunder by LICENSEE shall be payable in

                                 --------------------

         7.1 The Term of this AGREEMENT shall extend from the EFFECTIVE DATE set
forth hereinabove to the full end of the term or terms for which COAGULATION
PATENT RIGHTS have not expired and if only COAGULATION TECHNOLOGY RIGHTS are
licensed and no COAGULATION PATENT RIGHTS are applicable, then, on a per-product

<PAGE>


                  (a) upon thirty (30) days written notice if LICENSEE shall
         default in its obligation to make payments, if any are due, in
         accordance with Article VI or Article XIV hereunder; provided, however,
         LICENSEE may avoid such termination if before the end of such notice
         period LICENSEE cures its default;

                  (b) automatically if LICENSEE shall become bankrupt or
         insolvent and/or if the business of LICENSEE shall be placed in the
         hands of a receiver, assignee, or trustee, whether by voluntary act or
         LICENSEE or otherwise;

                  (c) upon ninety (90) days written notice if LICENSEE shall
         breach or default on any obligation under this AGREEMENT except as
         provided in Article VI or Article XIV; provided, however, LICENSEE may
         avoid such termination if before the end of such period LICENSEE
         notifies BOARD that such breach has been cured, states the manner of
         such cure and in fact the breach has been cured; or

                  (d) Under the provisions of Section 5.6 if invoked.

         7.3 Upon termination of this AGREEMENT for any cause, nothing herein
shall be construed to release either party of any obligation matured prior to
the effective date of such termination. LICENSEE may, after the effective date
of such termination, SELL all LICENSED PRODUCT and parts therefor that it may
have on hand at the date of termination, provided that it pays running royalty
earned thereon as provided in this AGREEMENT.

                       VIII. INFRINGEMENT BY THIRD PARTIES
                             -----------------------------

         8.1 Each party shall inform the other promptly in writing of any
alleged infringement of the COAGULATION PATENT RIGHTS by a third party,
including all details then available. LICENSEE shall have the right, but shall
not be obligated, to prosecute at its own expense any such infringements, and
BOARD agrees that LICENSEE may join BOARD as a plaintiff at the expense of


                                       16
<PAGE>


LICENSEE. If any infringement action commenced or defended solely by LICENSEE,
all expenses and all recovery for infringement shall be those of LICENSEE. In
any such action by LICENSEE, BOARD shall be entitled to receive an amount equal
to the applicable royalties on any recovery of profits and damages that is in
excess of LICENSEE's reasonable costs and expenses, including, but not limited
to, actual costs and expenses incurred to non-affiliated accountants, lawyers
and consultants. No settlement, consent judgment or other voluntary final
disposition of the suit may be entered into without BOARD's consent, which
consent shall not be unreasonably withheld, delayed or conditioned.

         8.2 If LICENSEE has not commenced legal action or been successful in
obtaining cessation of the infringement within ninety (90) days of written
notification from BOARD of such infringement, or if LICENSEE elects not to
continue prosecuting any legal action against an infringer, BOARD shall have the
right, but shall not be obligated, to prosecute at its own expense any such
infringement. BOARD may join LICENSEE as a plaintiff in any such infringement
suit at BOARD's expense. No settlement, consent judgment or other voluntary
final disposition of the suit may be entered into without LICENSEE's consent,
which consent shall not be unreasonably withheld, delayed or conditioned.

         8.3 In the event that LICENSEE and/or BOARD do not file suit against,
conclude settlement negotiations with, or grant a license to a substantial
infringer of COAGULATION PATENT RIGHTS within one (1) year of knowledge thereof,
then the parties will consult with one another in an effort to determine whether
a reasonably prudent licensee would institute litigation, conclude settlement
negotiations, and/or grant a license within the one (1) year time period
described above in order to enforce the patent in question in light of all
relevant business and economic factors (including, but not limited to, the
projected cost of such litigation, the likelihood of success on the merits, the
probable amount of any damage award, the prospects for satisfaction of any


                                       17
<PAGE>


judgment against the alleged infringer, the possibility of counterclaims against
LICENSEE and BOARD, the diversion of LICENSEE's human and economic resources,
the impact of any possible adverse outcome on LICENSEE, and the effect any
publicity might have on the respective reputations and goodwill of the parties).
If after such consultation, the parties have not reached agreement and LICENSEE
does not forthwith file suit against, enter into settlement negotiations with or
grant a license to the substantial infringer, then BOARD shall have the right to
enforce any COAGULATION PATENT RIGHT, licensed hereunder on behalf of itself and
LICENSEE (BOARD retaining all recoveries from such enforcement), and BOARD shall
have the right to reduce the license granted hereunder to nonexclusive in the
national jurisdiction in which suit is brought.

         8.4 If any infringement suit that either party brings to enforce the
COAGULATION PATENT RIGHTS, the other party shall at the request and expense of
the party bringing the suit, cooperate in all reasonable respects, including, to
the extent possible, obtaining the testimony of its employees and agents and
making available physical evidence in the possession of that party.

                                 IX. ASSIGNMENT
                                     ----------
         This AGREEMENT shall not be assignable or otherwise transferable by
LICENSEE without the prior written consent of BOARD, which consent shall not be
unreasonably withheld, except that LICENSEE may assign or otherwise transfer its
rights under this AGREEMENT to the following parties without obtaining BOARD's
consent: (i) a successor to LICENSEE's business, or a successor to that portion
of LICENSEE's business that pertains to the subject matter of the COAGULATION
PATENT RIGHTS or any COAGULATION TECHNOLOGY RIGHTS, and (ii) any entities
controlled by, controlling, or under common control with LICENSEE.

SOUTHWESTERN, and their respective Regents, officers, employees and agents
(each, an "INDEMNITEE") from and against any liability, loss or damage they may
suffer as a result of claims, demands, or causes of action whatsoever, including
without limitation those arising on account of any injury or death of persons or
damage to property caused by, or arising out of or resulting from, the exercise
or practice of the license granted hereunder by LICENSEE or its officers,
employees, agents or representatives; PROVIDED, HOWEVER, that LICENSEE shall not
be required to indemnify or hold harmless any INDEMNITEE, from any losses or
claims attributable to any infringement or alleged infringement of patents,
technology, trade secrets, or confidential or proprietary know-how or
information of third parties by the COAGULATION PATENT RIGHTS or the COAGULATION
TECHNOLOGY RIGHTS. Except as otherwise provided in this AGREEMENT, the
obligations of LICENSEE under this Section shall apply in full force whether or
not the claims and any losses resulted, or are alleged to have resulted, in
whole or in part from the acts or omissions of any INDEMNITEE; PROVIDED,
HOWEVER, that the foregoing indemnity shall not apply to any claims or losses
arising out of any act or omission constituting gross negligence, willful
malfeasance, misconduct or bad faith of any INDEMNITEE.

LICENSEE shall have the right to identify such parties and to disclose the terms

filing required by applicable securities laws or other applicable law or
regulation, provided that LICENSEE shall have given each such affected party at
least ten (10) business days prior written notice of the proposed text of any
such identification or disclosure for the purpose of giving each such affected
party the opportunity to comment on and suggest amendments to such proposed
text.

                         XIII. CONFIDENTIAL INFORMATION
                               ------------------------

documents marked "confidential" which are forwarded to one by the other shall be
received in strict confidence, used only for the purposes of this AGREEMENT, and

                           XIV. PATENTS AND INVENTIONS
                                ----------------------

         14.1 UT SOUTHWESTERN shall be responsible for the preparation, filing,

reasonable attorneys' fees (i) incurred by UT SOUTHWESTERN subsequent to the
EFFECTIVE DATE, or (ii) incurred by UT SOUTHWESTERN prior to the EFFECTIVE DATE
and for which invoices have been submitted to LICENSEE in connection with the
preparation, filing and maintenance of all patent applications and patents
included in COAGULATION PATENT RIGHTS; PROVIDED that patent counsel selected by
UT SOUTHWESTERN is reasonably acceptable to LICENSEE. Subsequent to the
EFFECTIVE DATE, UT SOUTHWESTERN shall consult with LICENSEE as to the

incorporated herein by reference, and shall furnish to LICENSEE copies of
documents relevant to such preparation, filing, prosecution or maintenance,
including without limitation invoices providing detailed descriptions of all
costs and expenses incurred by UT SOUTHWESTERN's patent counsel in connection
therewith, sufficiently prior to filing such documents or making any payment due
thereunder to allow for review and comment by LICENSEE. If, at any time,
LICENSEE shall elect not to pay the expenses of any patent application or patent
included in COAGULATION PATENT RIGHTS, LICENSEE shall so notify UT SOUTHWESTERN
within thirty (30) days of such consultation and shall thereby surrender its
rights under such patent application or patent; PROVIDED, HOWEVER, that LICENSEE
shall remain obligated to reimburse UT SOUTHWESTERN for any costs incurred with
respect to such patent application or patents prior to said election.

LICENSEE's reason(s) for its desire to transfer prosecution or maintenance to
another law firm and include information about the law firm and individual
patent attorneys, patent agents, and/or scientific advisors that may be assigned

SOUTHWESTERN with copies of all documents received or filed during prosecution
and/or maintenance thereof in a timely manner. In any event, LICENSEE shall
consult UT SOUTHWESTERN prior to abandonment of any claims of any patent
application for LICENSED SUBJECT MATTER at least sixty (60) days prior to
abandonment.

EXHIBIT 10.59


                                LICENSE AGREEMENT
                                -----------------


         This License Agreement ("Agreement") effective as of August 4, 1999
(the "Effective Date"), is entered into by and between NORTHWESTERN UNIVERSITY,
an Illinois corporation located at 633 Clark Street, Evanston, Illinois 60201
and TECHNICLONE CORPORATION, a Delaware corporation ("TECHNICLONE") located at
14282 Franklin Avenue, Tustin, California 92780-7017.

                                 R E C I T A L S

         A. In the course of research conducted at NORTHWESTERN UNIVERSITY,
Professor Alan Epstein (the "Inventor") has produced inventions, the titles of
which are also listed in Exhibit "A" (the "Inventions").

         B. WHEREAS, the Inventions described were made under support from the
National Institutes of Health of the Department of Health and Human Services and
NORTHWESTERN UNIVERSITY has acquired rights thereto pursuant to P.L. 96-517, and
if a conflict arises between the conditions of this Agreement and the rights of
the Federal Government, TECHNICLONE's rights would be subordinate to the
legitimate rights of the Federal Government, and

         C. TECHNICLONE has obtained a license to the Licensed Technology (as
hereinafter defined), and NORTHWESTERN UNIVERSITY granted such a license to
TECHNICLONE pursuant to that certain License Agreement dated June 12, 1985, as
amended pursuant to that certain Amendment effective October, 1987 (the "Prior
License Agreement").

         D. NORTHWESTERN UNIVERSITY and TECHNICLONE desire to amend and restate
that certain Prior License Agreement and desire that this Agreement supercede
the Prior License Agreement in its entirety.

         NOW, THEREFORE, in consideration of the foregoing, and the covenants
and promises contained herein, the sufficiency of which are hereby acknowledged
by the parties, NORTHWESTERN UNIVERSITY and TECHNICLONE hereby agree as follows:


                                    ARTICLE I

Licensed Product by TECHNICLONE, its Sublicensees or permitted assignees,
TECHNICLONE or its Sublicensees shall have the right to conduct the legal
defense, but shall not enter into any settlement, consent judgment or final
voluntary disposition that admits that any Licensed Product infringes any third
party right, without NORTHWESTERN UNIVERSITY's prior written consent to such
disposition, which consent shall not be unreasonably withheld or delayed. All

                                   INVENTIONS
                                   ----------


1.       "Hybridoma 173-9, Lym-1" (NU 8314-A)
         ------------------------------------

         A hybridoma clone, designated Lym-1, was produced from the fusion of
primed mouse splenocytes and mouse myeloma NS-a cells. Hybridoma Lym-1 produced
a murine IgG2a monoclonal antibody which recognizes a 31, 32, 33 and 35
kilodalton cell surface protein expressed in normal and malignant B lymphocytes.
Immunoperoxidase staining of a panel of normal human tissues shows that Lym-1
reacts with germinal center and mantle zone B lymphocytes and interdigitating
histiocytes of the lymph node, medullary dendritic cells of the thymus, and
weakly with surface epithlium of the colon. A subset of peripheral blood B cells
are positive and no reactivity has been observed in human bone marrow by flow
cytometric analysis. The antigen recognized by Lym-1 is not shed from the
surface of lymphoma cells either in cell culture or in patients and is not
modulated after Lym-1 binding. Lym-1 itself has been shown to have high avidity
to human lymphoma cells IN VIVO as demonstrated by radionuclide binding studies
in lymphoma patients using I-123 conjugates. Binding to normal tissues such as
the bone marrow, spleen, lymph node, liver, kidney, lung or central nervous
system has not been demonstrated in over 30 patients studied. Lym-1 has further
been found to be highly stable to radionuclide conjugation methods and may be
prepared as F(ab1)2 or F(ab) fragments without significant loss of antibody
activity. Collectively, these data suggest that Lym-1 will be an appropriate
reagent for IN VIVO diagnosis and therapy of the human B-cell lymphomas and
leukemias.


2.       "Hybridoma Clone 1010-9, Lym-2" (NU 8314-B)
         -------------------------------------------

         A hybridoma clone, designated Lym-2, was produced from the fusion of
primed mouse splenocytes and mouse myeloma NS-1 cells. Hybridoma Lym-2 produced
a murine IgG1 monoclonal antibody which recognizes a cell surface protein
expressed in normal and malignant B lymphocytes. Immunoperoxidase staining of a
panel of normal human tissues show that Pym-2 reacts with germinal center and
mantle zone B lymphocytes and interdigitating histiocytes of the lymph node. A
subset of peripheral blood B cells are positive and no reactivity has been
observed in human bone marrow by flow cytometric analysis. Because of the
remarkable specificity of Lym-2 for human B-cells and derived malignancies,
these data suggest that Lym-2 will be appropriate for reagent for in vivo
diagnostic and therapy of the human B-cell lymphomas and leukemias.

3.       "Hybridoma Clone 818-18, BM-1" (NU 8216-C)
         ------------------------------------------


         A hybridoma clone, designated 818-18, was produced from the fusion of
primed mouse splenocytes and mouse myeloma NS-1 cells. Clone 818-18 produces a
murine IgG1 monoclonal antibody which recognizes a nuclear antigen expressed in
human granulocytes and myeloid precursors and acute and chronic myeloid
leukemia. Immunoperoxidase staining with 818-18 on B5 fixed, paraffin embedded
clot preparations of bone marrow aspirates shows positive nuclear staining of
myeloid cells with normal non-specific background staining. The remarkable
specificity of this reagent and its ability to stain B5 fixed, paraffin embedded
tissues makes it a unique reagent for the diagnosis of myeloid derived
leukemias.
