                   Notes to Consolidated Financial Statements
                                  June 30, 1997

(1)   BASIS OF PRESENTATION

      In the opinion of management, the accompanying unaudited condensed
      consolidated financial statements contain all adjustments (consisting of
      normal recurring adjustments) necessary to present fairly the Company's
      financial position as of June 30, 1997 and December 31, 1996, and results
      of operations for the three months and six months ended June 30, 1997 and
      1996 and for the period from April 20, 1992 (date of incorporation) to
      June 30, 1997, and changes in cash flows for the six months ended June 30,
      1997 and 1996, and for the period from April 20, 1992 (date of
      incorporation) to June 30, 1997.

      These condensed consolidated statements should be read in conjunction with
      the Company's audited consolidated financial statements for the years
      ended December 31, 1996 and 1995, which are included as part of the
      Company's Annual Report on Form 10-KSB for the year ended December 31,
      1996.

      The Company's condensed consolidated financial statements include the
      accounts and results of operations of the Company and its wholly owned
      subsidiary, Optical Analytic, Inc. (OAI). All significant intercompany
      balances and transactions have been eliminated in consolidation.

      Certain items have been reclassified to conform with current financial
      statement presentation.

(2)   NOTE PAYABLE

      In May 1997, the Company entered into an agreement providing for a loan of
      $200,000 secured by existing equipment and a loan of up to $500,000 for
      the purchase of new equipment ("Equipment Loan"). In accordance with the
      Equipment Loan, loan payments will be made monthly over a three year term
      with a final balloon payment equal to 10% of the original loan. As of June
      30, 1997, there was $304,291 outstanding under the Equipment Loan at an
      effective interest rate of approximately 15.6%. In connection with the
      Equipment Loan, the Company issued warrants to purchase 27,000 shares of 
      the Company's common stock at $2.1875 per share. The warrants expire in
      May 2004.

      The Equipment Loan is secured by furniture and equipment with a net book
      value of $625,038 at June 30, 1997.

      Future minimum principal payments under the Equipment Loan as of June 30,
      1997 are as follows:

(4)   STOCK OPTION PLANS

      1993 Stock Option Plan

      The fair value of each stock option grant is estimated using the
      Black-Scholes option-pricing model with the following weighted-average
      assumptions used for grants in 1997: expected dividend yield 0.0%;
      expected volatility of 1.032%; risk-free interest rate of 6.53%; and an
      expected life of 7 years.

      In June 1997, the Company's shareholders approved the proposal to amend
      the Company's 1993 Stock Option Plan to increase the number of shares of
      common stock authorized and reserved for issuance from 1,049,850 shares to
      1,849,850.

      As of June 30, 1997, options to purchase 333,773 shares were exercisable
      under the option plan at the weighted average exercise price of $1.44.

      During 1997, the Company had the following activity under the 1993 Stock
      Option Plan:

      Pro Forma Disclosure

      The Company applies APB Opinion No. 25 in accounting for its stock option
      plans and, accordingly, no compensation cost has been recognized for its
      stock options in the financial statements. Had the Company determined
      compensation cost based on the fair value at the grant date for its stock
      options under SFAS No. 123, the Company's net loss and net loss per share
      would have been increased to the pro forma amounts indicated below:

<TABLE>
<CAPTION>
                                                             June 30, 1997

         Net loss per share            As reported           $     (0.19)

</TABLE>

      Pro forma net loss reflects only options granted in 1997, 1996 and 1995.
      Therefore, the full impact of calculating compensation cost for stock
      options under SFAS No. 123 is not reflected in the pro forma net income
      amounts presented above because compensation cost is reflected over the
      options' vesting period of four to five years and compensation cost for
      options granted prior to January 1, 1995 is not considered.

                   Notes to Consolidated Financial Statements
                                  June 30, 1997


(5)   LITIGATION

      The Company and five of its past or present directors and/or officers are
      named as defendants in Katz vs. Blech, 95 Civ. 7215 (S.D.N.Y ("Katz") and
      Degulis vs. LXR Biotechnology Inc., et al., 95 Civ. 4204 (S.D.N.Y)
      ("Degulis"). In addition, one of the five, Mark Germain, is named as a
      defendant in the above two cases and also in In re Blech Securities
      Litigation, ("In re Blech"). The Company was previously named as a
      defendant in In re Blech but was dismissed by the Court on June 6, 1996.

      All three cases are brought on behalf of classes of persons purchasing
      common shares of the Company prior to September 21, 1994, and assert
      claims arising out of the Company's Initial Public Offering and subsequent
      trading of those shares. The suits allege violations of Sections 11 and 12
      of the Securities Act of 1933 and Sections 10(b) and 20 of the Securities
      and Exchange Act of 1934, including misrepresentations and omissions in
      connection with the Initial Public Offering and manipulation of share
      prices. The suits also allege common law claims for fraud and deceit and
      seek punitive damages. The complaints allege that defendants, including
      the Company and the defendant directors and officers, failed to disclose
      in securities filings connected with the Initial Public Offering, the
      leveraged financial condition of the Company's underwriter, D. Blech and
      Company Incorporated ("D. Blech & Co.") and its principal David Blech. The
      suits further allege that defendants failed to disclose that D. Blech &
      Co. would act as principal market maker for the Company's shares following
      the Initial Public Offering, and that D. Blech & Co.'s extended financial
      commitments would affect its ability to maintain a market for the
      Company's shares. The suits also allege that defendants assisted or
      acquiesced in a post-offering scheme to manipulate the market for the
      Company's shares and artificially inflate share prices.

      The Company has agreed to indemnify and/or advance defense costs to each
      of the current or former officers and directors who are named as
      defendants in the litigation. A demand by the independent underwriter for
      contractual indemnity has been denied. Such denial is subject to contest
      by the underwriter. The Company and the underwriter have entered into a
      tolling agreement whereby the Company agreed that the running of any
      statute of limitations applicable to claims of the underwriter against the
      Company would be tolled until the earlier of June 30, 1998 and the
      termination of the tolling agreement.

      The Company's primary level directors and officers liability insurance
      carrier has tentatively agreed to provide coverage, subject to the terms
      and conditions of the policy, for the current and former directors and/or
      officers. There is no insurance coverage for the Company itself. The
      extent to which costs of defending the litigation will ultimately be
      covered by insurance is not yet known. The extent to which insurance would
      cover any settlement or judgment has not been determined and may not be
      determined until the litigation is completed.

      The Company denies any wrongdoing and is defending the above cases
      vigorously. While an adverse judgment or settlement could have a material
      adverse financial impact on the Company, the early stage of litigation,
      uncertainty as to whether any material judgment or settlement will result,
      and the possibility that some portion of any settlement or judgment may be
      covered by insurance make it impossible to predict at this time whether
      the litigation will have a material adverse financial impact on the
      Company.

(6)   LICENSE AND COLLABORATIVE RESEARCH AGREEMENTS

      University of Tennessee

      In January 1997, the Company entered into an exclusive license and
      three-year research agreement with the University of Tennessee and the
      University of Tennessee Research Corporation related to certain patent
      applications and technology. As consideration for the agreement, the
      Company agreed to fund research in the amount of $70,000 per year for
      three years, with the third year's funding contingent upon meeting certain
      milestones.

(6)   LICENSE AND COLLABORATIVE RESEARCH AGREEMENTS (CONTINUED)

      Oxford Asymmetry, Limited

      In April 1997, the Company entered into a research collaboration agreement
      with Oxford Asymmetry, Limited ("Oxford") for the purpose of discovering
      small molecule drug candidates that target specific apoptosis pathways. In
      exchange for the services to be provided by Oxford, the Company has agreed
      to make payments totaling $650,000 through February, 1998 and is obligated
      to make certain future royalty payments on any products the Company may
      develop under the agreement. As of June 30, 1997, the Company has made
      payments of $162,500 related to the Oxford agreement of which
      approximately $127,000 is included in research and development expense for
      the six months ended June 30, 1997.

      Boehringer Mannheim

      As of June 30, 1997, the Company has received approximately $68,000 from
      Boehringer to fund its research of Maspin for the treatment of cancer.
      The amount received has been recorded as revenue as of June 30, 1997. In
      addition, the Company has received $150,000 for the purchase of 37,500
      shares of the Company's common stock. (Note 3)

      Other Agreements

      The Company has committed to fund up to $435,000 under various other
      research and collaborative agreements and up to $490,000 under a clinical
      service agreement. In most cases, the Company's obligations under these
      agreements can be terminated upon 30 days notice.

(7)   RECENT ACCOUNTING PRONOUNCEMENTS

      The Financial Accounting Standards Board recently issued Statement of
      Financial Accounting Standards No. 128 ("SFAS No. 128"), "Earnings Per
      Share". SFAS No. 128 requires the presentation of basic earnings per share
      ("EPS") and, for companies with complex capital structures or potentially
      dilutive securities, such as convertible debt, options and warrants,
      diluted EPS. SFAS No. 128 is effective for annual and interim periods
      ending after December 31, 1997. The Company does not expect its net loss
      per share presentation will be affected by SFAS No. 128.

(8)   SUBSEQUENT EVENTS

      Notes Payable

      In July 1997, the Company drew down approximately $206,000 in funds under
      the Equipment Loan, resulting in a remaining amount of approximately
      $164,000 available under the Equipment Loan. (Note 2)

      Stock Options

      In August, 1997, pursuant to the 1993 Stock Option Plan, the Company 
      granted to employees options to purchase approximately 330,300 shares of
      Company's common stock at an exercise price of $1.875 per share. These
      options vest 25% after one year and as to 2.083% of the shares each month
      thereafter.

      such as "believe," "expects," "likely," "may" and "plans" are intended to
      identify forward looking statements, although not all forward looking
      statements contain these words. The following discussion and analysis
      should be read in conjunction with the Company's financial statements and
      accompanying notes included herein, the Company's Annual Report on Form
      10-KSB for the year ended December 31, 1996, the Company's Form 10-QSB for
      the quarter ended March 31, 1997 and "Factors Affecting Future Results"
      below.

      PLAN OF OPERATIONS

      The Company's resources are currently focused on the research and
      development programs for Cardiosol, Elirex, Maspin, SLDI, and Lexirin, on
      possible clinical trials of HK-Cardiosol and CP-Cardiosol, and on limited
      research in areas such as BAK, Fas(DELTA)TM, and SARP. The Company will
      also conduct limited research on new technology which may permit the sex
      of a fetus to be determined as early as six weeks after conception, based
      on an analysis of DNA in the mother's urine. The Company believes this
      technology may also have applications in cancer detection and diagnosis.
      In addition, the Company has entered into an agreement with Oxford
      Asymmetry, Limited ("Oxford") for the purpose of discovering small
      molecule drug candidates that target specific apoptosis pathways.

      The Company is focusing its research and development efforts relating to
      the suppression of apoptosis in the heart on the Cardiosol technology. The
      Company plans to file an Investigational Drug Exemption ("IDE") with the
      FDA to begin clinical studies of HK-Cardiosol for heart preservation in
      transplant patients by the third quarter of 1997. The Company also plans 
      to file an Investigational New Drug ("IND") application with the FDA to 
      begin clinical studies of CP-Cardiosol as a cardioplegic solution by the 
      end of 1997.

      The Company currently is conducting preclinical studies of Elirex in
      animals for ischemic heart attack, stroke and liver transplantation
      applications. Based on the results to date of the preclinical studies for
      Elirex, the Company expects to pursue a collaborative partnership for
      further research and development of Elirex, and to consider filing an IND
      to commence clinical studies within the next nine to twelve months.

      Pursuant to the Boehringer Letter of Intent, the Company and Boehringer
      are currently conducting preclinical studies to assess the efficacy and
      toxicity of Maspin. Based on the results of the studies, which are
      expected in the third quarter of 1997, the Company and Boehringer will
      determine whether to proceed with further research and development
      efforts. However, Boehringer has no obligation to proceed with the
      project.

      The Company expects to continue to support the efforts of the Perkin-Elmer
      Corporation ("Perkin-Elmer") to develop the Company's scanning laser
      digital imaging ("SLDI") technology.

      The Company completed its Phase I trials for Lexirin and preliminary
      results indicated it was tolerated in AIDS patients and that no adverse
      reactions were encountered. However, in light of the growing use of triple
      drug therapy for HIV infection and concomitant decrease in side effects
      suffered by patients infected with HIV, LXR has decided to reallocate its
      resources to the development of its candidate systems to preserve and
      protect organ function,  including HK-Cardiosol, CP-Cardiosol and Elirex,
      for which the Company believes there are larger markets and more pressing
      needs. The Company intends to continue to analyze the market for AIDS
      related diarrhea therapy outside the U.S. and to evaluate Lexirin for
      potential applications in other markets, including cancer chemotherapy and
      radiotherapy.

      The Company plans to seek additional corporate partners for its research
      and development activities. However, there can be no assurance that the
      Company will be able to secure any new corporate partner relationships. In
      addition to the studies mentioned above, the Company is funding research
      at the University of Tennessee during 1997, and may enter into research
      relationships with other universities and research institutions. The
      Company also regularly evaluates the possibility of licensing or otherwise
      acquiring technologies from third parties.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

      PLAN OF OPERATIONS (CONTINUED)

      As of June 30, 1997, the Company employed 62 employees, including 58
      full-time employees. Over the next 12 months, the Company expects to
      increase its number of employees to approximately 72 to support the
      Company's increased research and development efforts and expanding
      manufacturing and clinical trial activities. Further increases in
      employees may occur as the Company increases its spending efforts to
      undertake clinical studies.

      In 1996, the Company amended the terms of its laboratory and office lease
      to extend the term and add approximately 4,100 square feet of space. The
      additional space is being used for the Company's expanding clinical trial
      activities and new pilot GMP manufacturing facility for producing
      materials for clinical trials.

      The Company's capital expenditures for the first half of 1997 were
      approximately $660,000. The Company expects that capital expenditures for
      1997 will continue to increase as a result of the pilot manufacturing
      facility which is currently under construction. The Company estimates the
      total cost of constructing and equipping the new GMP manufacturing
      facility will be approximately $800,000 to $1,000,000, of which
      approximately $420,000 has been incurred as of June 30, 1997. The Company
      has secured the Equipment Loan of $700,000 to finance capital expenditures
      for 1997. Total capital expenditures, including amounts remaining for the
      manufacturing facility are expected to be approximately $600,000 over the
      next twelve months. In addition, the Company expects to receive
      approximately $400,000 in contributed equipment under the Perkin-Elmer
      License Agreement (as defined below).

      RESULTS OF OPERATIONS

      Six Months Ended June 30, 1997 compared to the Six Months Ended June 30,
      1996

      The Company had revenues of $85,996 and $108,193 for the three and six
      months ended June 30, 1997 compared to revenues of $59,702 and $70,246 for
      the three and six months ended June 30, 1996. The increase in revenue was
      primarily due to a $68,211 payment for funded research provided by
      Boehringer in the second quarter of 1997, partially offset by reduced
      grant revenues. The Company's remaining sources of revenues for 1997
      include grant revenues related to Maspin of approximately $17,000,
      potential research revenue of up to $182,000 under the Boehringer Letter
      of Intent and license fee revenue under a license agreement with the
      Perkin-Elmer relating to SLDI technology (the "Perkin-Elmer License
      Agreement"). The Company believes it has met a milestone under the
      Perkin-Elmer License Agreement and expects to receive $300,000 in cash
      milestone payments and $400,000 in equipment during the third quarter of
      1997. The Company does not have any commercially available products (other
      than the Company's Scanning Laser Digital Imager, being marketed by
      Perkin-Elmer) and does not anticipate generating any significant revenues
      for at least the next several years.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

      RESULTS OF OPERATIONS (CONTINUED)

      The Company's research and development expenses were $1,673,666 and
      $2,979,480 for the three and six months ended June 30, 1997 compared to
      $1,122,624 and $2,332,865 for the three and six months ended June 30,
      1996. These expenses included salaries and related benefits, laboratory
      supplies, depreciation of equipment, facility costs, consulting fees,
      research collaboration expenses, toxicology study costs, clinical trial
      costs, legal fees for patents and other research related expenditures.
      Research and development costs increased primarily due to increased salary
      and benefits costs resulting from an increase in the number of research
      personnel, increased research collaboration costs resulting from the new
      agreement with Oxford and increases in clinical trial and toxicology study
      costs. The increase in research and development expenses was partially
      offset by a decrease in patent legal fees, depreciation expense and 
      certain collaboration expenses resulting from the termination of research
      agreements with the University of Kentucky and the Dana Farber Cancer
      Institute.

      The Company expects research and development expenses to continue to
      increase over the next twelve months in order to continue the Company's
      research and development programs for Cardiosol, Elirex, Maspin, SLDI and
      Lexirin; to fund possible clinical trials of HK-Cardiosol and
      CP-Cardiosol; and to support limited research in areas such as Bak, SARP,
      Fas(DELTA)TM and certain new technology based upon the detection of DNA in
      urine. See "Plan of Operations" above.

      Additionally, in April 1997, the Company entered into a research
      collaboration agreement with Oxford for the purpose of discovering small
      molecule drug candidates that target specific apoptosis pathways. As of
      June 30, 1997, the Company has paid $162,500 under the Oxford Agreement
      and is committed to $487,500 in payments through February 1998.

      Although the Company plans for research and development spending to
      continue to increase substantially over the next several years as the
      Company expands its research and development efforts and undertakes
      clinical studies with respect to certain of its projects, such expansion
      of operations remain contingent upon the Company's ability to obtain
      additional amounts of capital resources. Unless and until such funds are
      received, research and development activities will be limited to the
      Company's available resources. See "Liquidity and Capital Resources"
      below.

      General and administrative expenses were $807,722 and $1,505,019 for the
      three and six months ended June 30, 1997 compared to $649,715 and
      $1,162,422 for the three and six months ended June 30, 1996. This increase
      is primarily due to increased personnel costs, increased legal costs
      related to litigation, and an increase in facility costs due to a larger
      facility. Future general and administrative expenses are anticipated to
      increase to support the Company's expansion of research and development
      activities and possibly due to increased legal expenses resulting from the
      securities lawsuits currently pending against the Company and certain of
      its past and present officers and directors.

      Interest income, net of interest expense, increased to $108,489 and
      $239,119 for the three and six months ended June 30, 1997 from $56,802 and
      $117,729 for the three and six months ended June 30, 1996. The increase in
      net interest income was due to interest earned on a larger average
      investment balance in the first half of 1997 as compared to the first half
      of 1996, as well as a decrease in interest expense in 1997. The Company
      expects interest expense to increase as a result of borrowings under the
      Equipment Loan. Further increases are expected as the Company borrows the
      remaining amount available under the Equipment Loan. See "Liquidity and
      Capital Resources" below.

      The Company's net loss increased to $2,287,303 and $4,137,987 for the
      three and six months ended June 30, 1997 compared to $1,660,135 and
      $3,315,912 for the three and six months ended June 30, 1996, reflecting
      the Company's increased expenses in 1997. As of June 30, 1997, the Company
      had an accumulated deficit of $27,653,706. The Company expects to continue
      to incur substantial losses over the next several years as it expands its
      research and development efforts and continues to undertake preclinical
      and clinical studies.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

      LIQUIDITY AND CAPITAL RESOURCES

      In January 1997, the Company received $150,000 from Boehringer for the
      purchase of 37,500 shares of the Company's common stock at a price of
      $4.00 per share in accordance with the Boehringer Letter of Intent. In
      addition, the Company received $1,278,700 in cash for the Private
      Placement receivable and approximately $330,000 in funds borrowed under
      the Company's Equipment Loan. As of June 30, 1997, the Company's sources
      of capital consisted of approximately (i) $6.7 million in cash and cash
      equivalents, (ii) interest from investments, (iii) $17,000 in currently
      committed grant revenues related to Maspin, (iv) potential research
      revenue of up to $182,000 under the Boehringer Letter of Intent, (v)
      approximately $300,000 in license fee revenue under the Perkin-Elmer
      License Agreement and (vi) approximately $400,000 of equipment to be
      contributed under the Perkin-Elmer License Agreement. In addition, during
      1997, the Company secured financing of approximately $700,000 in
      connection with the construction of the Company's pilot manufacturing
      facility, of which approximately $370,000 remains available under the
      Equipment Loan at June 30, 1997. The Company believes these resources are
      sufficient to fund the Company's operations through 1997. However, there
      can be no assurance that unanticipated events affecting the Company's
      resources will not result in the Company depleting its funds before that
      time.

      The Company does not have any committed sources of future equity or debt
      funding other than noted above. Accordingly, the Company will need to
      raise substantial additional capital to fund its operations, including the
      development of its lead compounds, beyond 1997. Although the Company is
      currently expending significant efforts to obtain the additional funding
      necessary to fund the Company's operations beyond 1997, there can be no
      assurance that additional funding will be available on favorable terms, if
      at all. Failure to raise additional funds in the relatively near future
      will have a material adverse effect on the Company.

      FACTORS AFFECTING FUTURE RESULTS

      Future Capital Needs; Uncertainty of Additional Funding

      The Company will require substantial additional capital to fund its
      operations, including its research and development programs and
      preclinical and clinical testing of its potential pharmaceutical and
      medical device products, and to conduct marketing of any products that may
      be developed. The Company's capital requirements depend on numerous
      factors, including the progress of its research and development programs,
      the progress of preclinical and clinical testing, the time and costs
      involved in obtaining regulatory approvals, the cost of filing,
      prosecuting, defending and enforcing any patent claims and other
      intellectual property rights, the cost of obtaining technological rights,
      competing technological and market developments, changes in the Company's
      existing research relationships, the ability of the Company to establish
      collaborative arrangements, the development of commercialization
      activities and arrangements, the cost of purchasing additional capital
      equipment, and legal expenses incurred in connection with defending
      certain lawsuits that have been brought against the Company (described
      above in Item 1). Based upon its current plans, the Company believes it
      has sufficient funds to meet the Company's operating expenses and capital
      requirements through 1997. However, there can be no assurance that
      unanticipated changes or other events affecting the Company's operating
      expenses will not result in the expenditure of available funds before the
      end of 1997.

      The Company will need to raise substantial additional capital to fund its
      operations, including the development of its lead compounds. The Company
      intends to seek additional funding through public or private financings
      and/or collaborative or other arrangements with corporate partners. There
      can be no assurance, however, that additional funding will be available
      from any of these sources, or if available, will be available on favorable
      or acceptable terms. If adequate funds are not available, the Company may
      be required to delay, scale back or eliminate one or more of its research
      and development programs, including but not limited to the development of
      its lead compounds. If the Company raises additional funds through public
      or private financings, such financings may result in substantial dilution
      to the Company's stockholders. In 1996, the Company issued a total of
      approximately 15 million shares and warrants therefor (or approximately
      62% of the Company's total current outstanding stock, assuming all shares
      underlying warrants and other rights are outstanding) to raise needed
      funds. If the Company is able to enter into corporate partnerships to
      obtain funds, such arrangements will require the Company to relinquish
      certain rights to certain of its technologies on potential products that
      the Company would not otherwise relinquish. Failure to obtain additional
      funds will have a material adverse effect on the Company's operations.

      Early Stage of Development; Regulatory, Technological and Other
      Uncertainties

      LXR is at an early stage of development. Other than the SLDI microscope, a
      prototype of which was sold to Perkin-Elmer all of the Company's potential
      pharmaceutical and medical device products are currently in research and
      development, and no revenues from the sale of such potential products have
      been generated to date. Substantially all of the Company's resources have
      been and for the foreseeable future will continue to be dedicated to the
      Company's research programs and the development of potential
      pharmaceutical and medical device products emanating therefrom. There can
      be no assurance that the Company will be able to develop a commercial
      product from any of these projects. All of the Company's drug and medical
      device candidates are in preclinical development. While the Company
      believes that the results attained to date in such preclinical studies
      generally support further research and development of these potential
      products, results attained in preclinical studies are not necessarily
      indicative of results that will be obtained in human clinical testing.
      Additionally, the Company has not previously met its forecasted schedule
      for introducing products into clinical trials. Finally, the Company
      recently reassessed the market for Lexirin in the treatment of AIDS
      patents and decided not to proceed with further U.S. clinical trials of
      Lexirin in AIDS patients at this time. Similar assessments of market
      opportunities and priorities for allocating available resources may again
      affect the Company's decision to undertake or continue preclinical and/or
      clinical trials or otherwise continue to pursue research and development
      programs for its potential products.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

      FACTORS AFFECTING FUTURE RESULTS (CONTINUED)

      The potential pharmaceutical products currently under development by the
      Company will require significant additional research and development and
      preclinical testing and will require extensive clinical testing prior to
      submission of any regulatory application for commercial use. The Company's
      potential pharmaceutical products are subject to the risks of failure
      inherent in the development of pharmaceutical products based on new
      technologies. These risks include the possibilities that the Company's
      novel approach to diagnosis and therapy will not be successful; that any
      or all of the Company's potential pharmaceutical products will be found to
      be unsafe, ineffective or toxic, or otherwise fail to receive necessary
      regulatory clearances; that the products, if safe and effective, will be
      difficult to manufacture on a large scale or uneconomical to market; that
      proprietary rights of third parties will preclude the Company from
      marketing such products; or that third parties will market superior or
      equivalent products. As a result, there can be no assurance that any of
      the Company's research and development activities will be successfully
      completed; that clinical trials will be allowed by the FDA or other
      regulatory authorities; that clinical trials will commence as planned;
      that required United States or foreign regulatory approvals will be
      obtained on a timely basis, if at all; or that any products for which
      approval is obtained will result in any commercially viable pharmaceutical
      products.

      The Company's product development efforts are based on the novel
      scientific approach of therapeutic apoptosis modulation, which has not
      been widely studied. There is, therefore, substantial risk that this
      approach will not prove to be successful. Moreover, the Company is
      applying this novel approach to discover new treatments for a variety of
      diseases that are also the subject of research and development efforts by
      other companies, many of which are much larger and better funded. 
      Biotechnology in general and apoptosis modulation in particular are
      relatively new fields in which there is a potential for extensive
      technological innovation in relatively short periods of time. The
      Company's competitors may succeed in developing technologies or products
      that are more effective than those of the Company. Rapid technological
      change or developments by others may result in the Company's technology or
      proposed products becoming obsolete or noncompetitive.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

      FACTORS AFFECTING FUTURE RESULTS (CONTINUED)

      History of Losses; Uncertainty of Future Profitability

      The Company has incurred significant operating losses since its inception
      in 1992. At June 30, 1997, the Company had an accumulated deficit of
      approximately $27.7 million. The Company will be required to conduct
      significant research, development, testing and regulatory compliance
      activities that, together with projected general and administrative
      expenses, are expected to result in significant operating losses for at
      least the next several years. Revenues, if any, that the Company may
      receive in the next few years will be limited to potential payments from
      Perkin-Elmer under the Perkin-Elmer License Agreement, potential payments
      from Boehringer under the non-binding Boehringer Letter of Intent,
      revenues from grants currently awarded to the Company and which may be
      awarded to the Company in the future, payments under research or product
      development relationships that the Company may hereafter establish,
      payments under license agreements that the Company may hereafter
      establish, sales of products that the Company may acquire in the future,
      and interest payments. There can be no assurance, however, that the
      Company will (i) receive any additional funds other than the $300,000 in
      license fee revenue and $400,000 in contributed equipment under the
      Perkin-Elmer License Agreement, as Perkin-Elmer may terminate such
      agreement at any time in its discretion, (ii) be successful in its
      collaboration with Boehringer or that such relationship will be expanded
      beyond its current very limited scope, (iii) be able to establish any
      additional relationships, (iv) enter into any license agreements, or (v)
      acquire any products in the future. The Company's ability to achieve
      profitability depends upon its ability successfully to complete either
      alone or with others, development of its potential products, conduct
      clinical trials, obtain required regulatory approvals, and manufacture and
      market its products or to enter into license agreements on acceptable
      terms. The Company may never achieve significant revenue or profitable
      operations.

      Dependence on Others; Collaborations

      The Company's strategy for the research, development and commercialization
      of its potential products may require the Company to enter into various
      arrangements with corporate and academic collaborators, licensors,
      licensees and others, in addition to those already established, and the
      Company may therefore be dependent upon the subsequent success of outside
      parties in performing their responsibilities. For example, the Company has
      provided Perkin-Elmer with significant exclusive rights to its SLDI
      product, and is dependent on Perkin-Elmer to satisfactorily commercialize
      such product so that the Company will receive remuneration for its efforts
      in this area. There can be no assurance that Perkin-Elmer's efforts to
      commercialize this product will be successful, or that the Company will
      receive any such remuneration. There can also be no assurance that the
      Company will be able to establish additional collaborative arrangements or
      license agreements to develop and commercialize its potential products, or
      that any of its collaborative arrangements or license agreements will be
      successful. Moreover, certain of the

                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

      FACTORS AFFECTING FUTURE RESULTS (CONTINUED)

      collaborative arrangements that the Company may enter into in the future
      may place responsibility for preclinical testing and human clinical trials
      and for preparing and submitting applications for regulatory approval for
      potential products on the collaborative partner. Should a collaborative
      partner fail to develop or commercialize successfully any potential
      product to which it has rights, the Company's business may be adversely
      affected. In addition, there can be no assurance that collaborators will
      not be pursuing alternative technologies or developing products either on
      their own or in collaboration with others, including the Company's
      competitors, as a means for developing treatments for the diseases or
      disorders targeted by such partners' collaborative programs with the
      Company.

                             LXR BIOTECHNOLOGY INC.

                             1993 STOCK OPTION PLAN

                           As adopted May 20, 1993 and
                        amended through February 11, 1997




         1. PURPOSE. This 1993 Stock Option Plan ("Plan") is established as a
compensatory plan to attract, retain and provide equity incentives to selected
persons to promote the financial success of LXR Biotechnology Inc., a Delaware
corporation, (the "Company"). Capitalized terms not previously defined herein
are defined in Section 17 of this Plan.

         2. TYPES OF OPTIONS AND SHARES. Options granted under this Plan (the
"Options") may be either (a) incentive stock options ("ISOs") within the meaning
of Section 422 of the Internal Revenue Code of 1986, as amended (the "Revenue
Code"), or (b) nonqualified stock options ("NQSOs"), as designated at the time
of grant. The shares of stock that may be purchased upon exercise of Options
granted under this Plan (the "Shares") are shares of the common stock, $0.0001
par value per share, of the Company.

         3. NUMBER OF SHARES. The aggregate number of Shares that may be issued
pursuant to Options granted under this Plan is 1,849,850 Shares, subject to
adjustment as provided in this Plan. "Named Executive Officers" (as that term is
defined in Item 402(a)(3) of Regulation S-K promulgated under the Exchange Act
of 1934, as amended, (the "Exchange Act") shall each be eligible to receive up
to an aggregate maximum of 333,333 Shares over the term of the Plan. If any
Option expires or is terminated without being exercised in whole or in part, the
unexercised or released Shares from such Option shall be available for future
grant and purchase under this Plan. At all times during the term of this Plan,
the Company shall reserve and keep available such number of Shares as shall be
required to satisfy the requirements of outstanding Options under this Plan.

         4. ELIGIBILITY. Options may be granted to employees, officers,
directors, consultants, independent contractors and advisers (provided such
consultants, contractors and advisers render bona fide services not in
connection with the offer and sale of securities in a capital-raising
transaction) of the Company or any Parent, Subsidiary or Affiliate of the
Company. ISOs may be granted only to employees (including officers and directors
who are also employees) of the Company or a Parent or Subsidiary of the Company.
The Committee (as defined in Section 14) in its sole discretion shall select the
recipients of Options ("Optionees"). An Optionee may be granted more than one
Option under this Plan. The Company may also, from time to time, substitute or
assume outstanding options granted by another company, whether in connection
with an acquisition of such other company or otherwise, by either (a) granting
an Option under this Plan in replacement of the option assumed by the Company,
or (b) treating the assumed option as if it had been granted under this Plan if
the terms of such assumed option could be applied to an Option granted under
this Plan. Such substitution or assumption shall be permissible if the holder of
the substituted or assumed option would have been eligible to be granted an
Option hereunder if the other company had applied the rules of this Plan to such
grant.

<PAGE>   2

         5. TERMS AND CONDITIONS OF OPTIONS. The Committee shall determine
whether each Option is to be an ISO or an NQSO, the number of Shares subject to
the Option, the exercise price of the Option, the period during which the Option
may be exercised, and all other terms and conditions of the Option, subject to
the following:


                  5.1 Form of Option Grant. Each Option granted under this Plan
shall be evidenced by a written Stock Option Grant (the "Grant") in such form
(which need not be the same for each Optionee) as the Committee shall from time
to time approve, which Grant shall comply with and be subject to the terms and
conditions of this Plan.


                  5.2 Date of Grant. The date of grant of an Option shall be the
date on which the Committee makes the determination to grant such Option unless
otherwise specified by the Committee. The Grant representing the Option will be
delivered to Optionee with a copy of this Plan within a reasonable time after
the granting of the Option.


                  5.3 Exercise Price. The exercise price of an Option shall be
not less than 100% of the Fair Market Value of the Shares on the date the Option
is granted. The exercise price of any Option granted to a person owning more
than l0% of the total combined voting power of all classes of stock of the
Company or any Parent or Subsidiary of the Company ("Ten Percent Shareholder")
shall not be less than 110% of the Fair Market Value of the Shares on the date
the Option is granted.


                  5.4 Exercise Period. Options shall be exercisable within the
times or upon the events determined by the Committee as set forth in the Grant;
provided, however, that no Option shall be exercisable after the expiration of
ten (10) years from the date the Option is granted, and provided further that no
ISO granted to a Ten Percent Stockholder shall be exercisable after the
expiration of five (5) years from the date the Option is granted.


                  5.5 Limitations on ISOs. The aggregate Fair Market Value
(determined as of the time an Option is granted) of stock with respect to which
ISOs are exercisable for the first time by an Optionee during any calendar year
(under this Plan or under any other incentive stock option plan of the Company
or any Parent or Subsidiary of the Company) shall not exceed $100,000. If the
Fair Market Value of Shares with respect to which ISOs are exercisable for the
first time by an Optionee during any calendar year exceeds $100,000, the Options
for the first $100,000 worth of Shares to become exercisable in such year shall
be ISOs and the Options for the amount in excess of $100,000 that becomes
exercisable in that year shall be NQSOs. In the event that the Revenue Code or
the regulations promulgated thereunder are amended after the effective date of
this Plan to provide for a different limit on the Fair Market Value of Shares
permitted to be subject to ISOs, such different limit shall be incorporated
herein and shall apply to any Options granted after the effective date of such
amendment.


                  5.6 Options Non-Transferable. Options granted under this Plan,
and any interest therein, shall not be transferable or assignable by Optionee,
and may not be made subject to execution, attachment or similar process,
otherwise than by will or by the laws of descent and distribution or pursuant to
a qualified domestic relations order as defined by the Revenue Code or Title I
of the Employee Retirement Income Security Act, or the rules thereunder, and
shall be exercisable during the lifetime of Optionee only by Optionee; provided,
however, that NQSOs held by  



                                      -2-
<PAGE>   3

officers or directors of the Company or other persons whose transactions in the
Company's common stock are subject to Section 16(b) of the Exchange Act may be
transferred to such family members, trusts and charitable institutions as the
Committee, in its sole discretion, shall approve at the time of the grant of
such Option.


                  5.7 Assumed Options. In the event the Company assumes an
option granted by another company, the terms and conditions of such option shall
remain unchanged (except the exercise price and the number and nature of shares
issuable upon exercise, which will be adjusted appropriately pursuant to Section
424 of the Revenue Code). In the event the Company elects to grant a new option
rather than assuming an existing option (as specified in Section 4), such new
option need not be granted at Fair Market Value on the date of grant and may
instead be granted with a similarly adjusted exercise price.


         6.       EXERCISE OF OPTIONS.


                  6.1 Notice. Options may be exercised only by delivery to the
Company of a written stock option exercise agreement (the "Exercise Agreement")
in a form approved by the Committee (which need not be the same for each
Optionee), stating the number of Shares being purchased, the restrictions
imposed on the Shares, if any, and such representations and agreements regarding
Optionee's investment intent and access to information, if any, as may be
required by the Company to comply with applicable securities laws, together with
payment in full of the exercise price for the number of Shares being purchased.


                  6.2 Payment. Payment for the Shares may be made in cash (by
check) or, where approved by the Committee in its sole discretion and where
permitted by law: (a) by cancellation of indebtedness of the Company to the
Optionee; (b) by surrender of shares of common stock of the Company having a
Fair Market Value equal to the applicable exercise price of the Options that
have been owned by Optionee for more than six (6) months (and which have been
paid for within the meaning of the Securities and Exchange Commission ("SEC")
Rule 144 and, if such Shares were purchased from the Company by use of a
promissory note, such note has been fully paid with respect to such shares), or
were obtained by Optionee in the open public market; (c) by waiver of
compensation due or accrued to Optionee for services rendered; (d) provided that
a public market for the Company's stock exists, through a "same day sale"
commitment from Optionee and a broker-dealer that is a member of the National
Association of Securities Dealers (an "NASD Dealer") whereby Optionee
irrevocably elects to exercise the Option and to sell a portion of the Shares so
purchased to pay for the exercise price and whereby the NASD Dealer irrevocably
commits upon receipt of such Shares to forward the exercise price directly to
the Company; (e) provided that a public market for the Company's stock exists,
through a "margin" commitment from Optionee and an NASD Dealer whereby Optionee
irrevocably elects to exercise the Option and to pledge the Shares so purchased
to the NASD Dealer in a margin account as security for a loan from the NASD
Dealer in the amount of the exercise price, and whereby the NASD Dealer
irrevocably commits upon receipt of such Shares to forward the exercise price
directly to the Company; or (f) by any combination of the foregoing.



                                      -3-
<PAGE>   4

                  6.3 Withholding Taxes. Prior to issuance of the Shares upon
exercise of an Option, Optionee shall pay or make adequate provision for any
federal or state withholding obligations of the Company, if applicable. Where
approved by the Committee in its sole discretion, Optionee may provide for
payment of withholding taxes upon exercise of the Option by requesting that the
Company retain Shares with a Fair Market Value equal to the minimum amount of
taxes required to be withheld, determined on the date that the amount of tax to
be withheld is to be determined. All elections by Optionees to have Shares
withheld for this purpose shall be made in accordance with the requirements
established by the Committee and be in writing in a form acceptable to the
Committee.

                  6.4 Limitations on Exercise. Notwithstanding the exercise
periods set forth in the Grant, exercise of an Option shall always be subject to
the following:

                           6.4.1 If Optionee ceases to be employed by the
Company or any Parent, Subsidiary or Affiliate of the Company for any reason
except death or disability, Optionee may exercise such Optionee's Options to the
extent (and only to the extent) that they would have been exercisable upon the
date of termination, within ninety (90) days after the date of termination (or
such shorter time period as may be specified in the Grant).

                           6.4.2 If Optionee's employment with the Company or
any Parent, Subsidiary or Affiliate of the Company is terminated because of the
death of Optionee or disability of Optionee, Optionee's Options may be exercised
to the extent (and only to the extent) that they would have been exercisable by
Optionee on the date of termination, by Optionee (or Optionee's legal
representative) within twelve (12) months after the date of termination (or such
shorter time period as may be specified in the Grant), but in any event no later
than the expiration date of the Options; provided that in the event of
termination due to disability, other than as defined in Section 22(a)(3) of the
Internal Revenue Code, as amended, any ISO which remains exercisable after 90
days after the date of termination shall be deemed a NQSO.

                           6.4.3 The Committee shall have discretion to
determine whether Optionee has ceased to be employed by the Company or any
Parent, Subsidiary or Affiliate of the Company and the effective date on which
such employment terminated.

                           6.4.4 In the case of an Optionee who is a director,
independent consultant or adviser, the Committee will have the discretion to
determine whether Optionee is "employed by the Company or any Parent, Subsidiary
or Affiliate of the Company" pursuant to the foregoing Sections.

                           6.4.5 The Committee may specify a reasonable minimum
number of Shares that may be purchased on any exercise of an Option, provided
that such minimum number will not prevent Optionee from exercising the full
number of Shares as to which the Option is then exercisable.

                           6.4.6 An Option shall not be exercisable unless such
exercise is in compliance with the Securities Act of 1933, as amended (the
"Securities Act"), all applicable state securities laws and the requirements of
any stock exchange or national market system upon


                                      -4-
<PAGE>   5

which the Shares may then be listed, as they are in effect on the date of
exercise. The Company shall be under no obligation to register the Shares with
the SEC or to effect compliance with the registration, qualification or listing
requirements of any state securities laws, stock exchange or national market
system, and the Company shall have no liability for any inability or failure to
do so.

         7. RESTRICTIONS ON SHARES. At the discretion of the Committee, the
Company may reserve to itself and/or its assignee(s) in the Grant a right of
first refusal to purchase all Shares that an Optionee (or a subsequent
transferee) may propose to transfer to a third party. Further, at the discretion
of the Committee, the Company may reserve to itself and/or its assignee(s) in
the Grant a right to repurchase a portion of or all Shares held by an Optionee
upon Optionee's termination of employment or service with the Company or a
Parent, Subsidiary or Affiliate of the Company, for any reason within a
specified time as determined by the Committee at the time of grant at Optionee's
original purchase price, the Fair Market Value of such Shares or a price
determined by a formula or other provision set forth in the Grant.

         8. MODIFICATION, EXTENSION AND RENEWAL OF OPTIONS. The Committee shall
have the power to modify, extend or renew outstanding Options and to authorize
the grant of new Options in substitution therefor, provided that any such action
may not, without the written consent of Optionee, impair any rights under any
Option previously granted. Any outstanding ISO that is modified, extended,
renewed or otherwise altered shall be treated in accordance with Section 424(h)
of the Revenue Code. The Committee shall have the power to reduce the exercise
price of outstanding Options without the consent of Optionees by a written
notice to the Optionees affected; provided, however, that the exercise price per
Share may not be reduced below the minimum exercise price that would be
permitted under Section 5.3 of this Plan for Options granted on the date the
action is taken to reduce the exercise price; and provided that the exercise
price per Share may not be reduced below the par value per Share.

          9. STOCK OWNERSHIP; FINANCIAL STATEMENTS. No Optionee shall have any
of the rights of a stockholder with respect to any Shares subject to an Option
until such Option is properly exercised. No adjustment shall be made for
dividends or distributions or other rights for which the record date is prior to
such date, except as provided in this Plan. However, the Company shall provide
to each Optionee, during the period for which Optionee has one or more Options
outstanding, copies of the financial statements of the Company, consisting of,
at a minimum, a balance sheet and an income statement, at least annually. The
Company shall not be required to provide such information to key employees whose
duties in connection with the Company assume their access to equivalent
information.

         10. NO OBLIGATION TO EMPLOY. Nothing in this Plan or any Option granted
under this Plan shall confer on any Optionee any right to continue in the employ
of, or other relationship with, the Company or any Parent, Subsidiary or
Affiliate of the Company or limit in any way the right of the Company or any
Parent, Subsidiary or Affiliate of the Company to terminate Optionee's
employment or other relationship at any time, with or without cause.

         11. ADJUSTMENT OF OPTION SHARES. In the event that the number of
outstanding shares of common stock of the Company is changed by a stock
dividend, stock split, reverse stock split, recapitalization, combination,
reclassification or similar change in the capital 



                                      -5-
<PAGE>   6

structure of the Company without consideration, or if a substantial portion of
the assets of the Company are distributed, without consideration in a spin-off
or similar transaction, to the stockholders of the Company, the number of Shares
available under this Plan and the number of Shares subject to outstanding
Options and the exercise price per Share of such Options shall be
proportionately adjusted, subject to any required action by the Board of
Directors (the "Board") or stockholders of the Company and compliance with
applicable securities laws; provided, however, that a fractional share shall not
be issued upon exercise of any Option and any fractions of a Share that would
have resulted shall either be cashed out at Fair Market Value or the number of
Shares issuable under the Option shall be rounded up to the nearest whole
number, as determined by the Committee; and provided further that the exercise
price may not be decreased to below the par value, if any, for the Shares.

         12.      ASSUMPTION OF OPTIONS BY SUCCESSORS.

                  12.1 Assumption or Substitution. In the event of (a) a merger
or consolidation in which the Company is not the surviving corporation (other
than a merger or consolidation with a wholly owned subsidiary, a
reincorporation, or other transaction in which there is no substantial change in
the stockholders of the corporation and the Options granted under this Plan are
assumed or replaced by the successor corporation, which assumption shall be
binding on all Optionees), (b) a dissolution or liquidation of the Company, (c)
the sale of substantially all of the assets of the Company, or (d) any other
transaction which qualifies as a "corporate transaction" under Section 424(a) of
the Revenue Code wherein the stockholders of the Company give up all of their
equity interest in the Company (except for the acquisition, sale or transfer of
all or substantially all of the outstanding shares of the Company), any or all
outstanding Options may be assumed or replaced by the successor corporation,
which assumption shall be binding on all Optionees. In the alternative, the
successor corporation may substitute an equivalent option or provide
substantially similar consideration to Optionees as was provided to stockholders
(after taking into account the existing provisions of Optionee's options, such
as the exercise price and the vesting schedule). The successor corporation may
also issue, in place of outstanding shares of the Company held by Optionee as a
result of the exercise of an Option that is subject to repurchase, substantially
similar shares or other property subject to similar repurchase restrictions no
less favorable to Optionee.

                  12.2 Expiration. In the event such successor corporation, if
any, refuses to assume or substitute Options, as provided above, pursuant to a
transaction described in Section 12.1 above, or there is no successor
corporation, and if the Company is ceasing to exist as a separate corporate
entity, the Options shall, notwithstanding any contrary terms in the Grant,
expire on (and, in the case of a transaction described in Subsection 12.1(a)
above, if the Company has reserved to itself a right to repurchase Shares issued
on exercise of Options at the original purchase price of such Shares, such right
shall terminate on), a date at least 20 days after the Board gives written
notice to Optionees specifying the terms and conditions of such termination.

                  12.3 Additional Provisions. Subject to the foregoing
provisions of this Section 12, in the event of the occurrence of any transaction
described in Section 12.1, any outstanding Option shall be treated as provided
in the applicable agreement or plan of merger, consolidation, dissolution,
liquidation, sale of assets or other "corporate transaction".

         13. ADOPTION AND STOCKHOLDER APPROVAL. This Plan shall become effective
on the date that it is adopted by the Board of the Company. This Plan shall be
approved by the stockholders of the Company, in any manner permitted by
applicable corporate law, within twelve months before or after the date this
Plan is adopted by the Board. Upon the effective date of the Plan, the Board may
grant Options pursuant to this Plan; provided that, in the event that
Stockholder approval is not obtained within the time period provided herein, all
Options granted hereunder shall terminate. No Option that is issued as a result
of any increase in the number of shares authorized to be issued under this Plan
shall be exercised prior to the time such increase has been approved by the
Stockholders of the Company and all such Options granted pursuant to such
increase shall similarly terminate if such Stockholder approval is not obtained.

         14. ADMINISTRATION. This Plan may be administered by the Board or a
committee appointed by the Board (the "Committee"). If two or more members of
the Board are Outside Directors, the Committee will be comprised of at least two
(2) members of the Board, all of whom are Outside Directors. As used in this
Plan, references to the "Committee" shall mean either the committee appointed by
the Board to administer this Plan or the Board if no committee has been
established. The interpretation by the Committee of any of the provisions of
this Plan or any Option granted under this Plan shall be final and binding upon
the Company and all persons having an interest in any Option or any Shares
purchased pursuant to an Option. The Committee may delegate to officers of the
Company the authority to grant Options under this Plan to Optionees who are not
officers or directors of the Company or other persons whose transactions in the
Company's common stock are subject to Section 16(b) of the Exchange Act.

         15. TERM OF PLAN. Options may be granted pursuant to this Plan from
time to time within a period of ten (10) years after the date on which this Plan
is adopted by the Board.

         16. AMENDMENT OR TERMINATION OF PLAN. The Committee may at any time
terminate or amend this Plan in any respect including (but not limited to)
amendment of any form of grant, exercise agreement or instrument to be executed
pursuant to this Plan; provided, however, that the Committee shall not, without
the approval of the stockholders of the Company, amend this Plan in any manner
that requires such stockholder approval pursuant to the Revenue Code or the
regulations promulgated thereunder as such provisions apply to ISO plans.

         17. CERTAIN DEFINITIONS. As used in this Plan, the following terms
shall have the following meanings:

                  17.1 "Parent" means any corporation (other than the Company)
in an unbroken chain of corporations ending with the Company if, at the time of
the granting of the Option, each of such corporations other than the Company
owns stock possessing 50% or more of the total combined voting power of all
classes of stock in one of the other corporations in such chain.

                  17.2 "Subsidiary" means any corporation (other than the
Company) in an unbroken chain of corporations beginning with the Company if, at
the time of granting of the Option, each of the corporations other than the last
corporation in the unbroken chain owns stock possessing 50% or more of the total
combined voting power of all classes of stock in one of the other corporations
in such chain.

                  17.3 "Affiliate" means any corporation that directly, or
indirectly through one or more intermediaries, controls or is controlled by, or
is under common control with, another corporation, where "control" (including
the terms "controlled by" and "under common control with") means the possession,
direct or indirect, of the power to cause the direction of the management and
policies of the corporation, whether through the ownership of voting securities,
by contract or otherwise.

                  17.4 "Fair Market Value" shall mean the fair market value of
the Shares as determined by the Committee from time to time in good faith. If a
public market exists for the Shares, the Fair Market Value shall be the average
of the last reported bid and asked prices for common stock of the Company on the
last trading day prior to the date of determination (or the average closing
price over the number of consecutive working days preceding the date of
determination as the Committee shall deem appropriate) or, in the event the
common stock of the Company is listed on a stock exchange or on the Nasdaq
National Market, the Fair Market Value shall be the closing price on such
exchange or quotation system on the last trading day prior to the date of
determination (or the average closing price over the number of consecutive
working days preceding the date of determination as the Committee shall deem
appropriate).

                  17.5 "Outside Director" shall mean any director who is not (i)
a current employee of the Company or any Parent, Subsidiary or Affiliate of the
Company, (ii) a former employee of the Company or any Parent, Subsidiary or
Affiliate of the Company who is receiving compensation for prior services (other
than benefits under a tax-qualified pension plan), (iii) a current or former
officer of the Company or any Parent, Subsidiary or Affiliate of the Company or
(iv) currently receiving compensation for personal services in any capacity,
other than as a director, from the Company or any Parent, Subsidiary or
Affiliate of the Company; provided, however, that at such time as the term
"Outside Director", as used in Section 162(m) is defined in regulations
promulgated under Section 162(m) of the Revenue Code, "Outside Director" shall
have the meaning set forth in such regulations, as amended from time to time and
as interpreted by the Internal Revenue Service.

                                    [     ]   Nonqualified Stock Option

         1. GRANT OF OPTION. LXR Biotechnology Inc., a Delaware corporation (the
"Company"), hereby grants to the optionee named above ("Optionee") an option
(this "Option") to purchase the total number of shares of common stock $0.0001
par value per share, of the Company set forth above (the "Shares") at the
exercise price per share set forth above (the "Exercise Price"), subject to all
of the terms and conditions of this Stock Option Grant (this "Grant") and the
Company's 1993 Stock Option Plan, as amended to the date hereof (the "Plan"). If
designated as an Incentive Stock Option above, this Option is intended to
qualify as an "incentive stock option" ("ISO") within the meaning of Section 422
of the Internal Revenue Code of 1986, as amended (the "Revenue Code"). Unless
otherwise defined herein, capitalized terms used herein shall have the meanings
ascribed to them in the Plan.

         2. EXERCISE PERIOD OF OPTION. Subject to the terms and conditions of
the Plan and this Grant, this Option shall become exercisable as to portions of
the Shares as follows: (a) This Option shall not be exercisable with respect to
any of the Shares until __________, 199__ (the "First Vesting Date"); (b) if

Vesting Date this Option shall become exercisable as to ______ percent (_____%)
of the Shares; and (c) thereafter this Option shall become exercisable as to an
additional ________ percent (______%) of the Shares on the ________ day of each
month following the First Vesting Date if Optionee has remained continuously
employed by the Company at all times on or prior to the relevant vesting date;
provided that Optionee shall in no event be entitled under this Option to
purchase a number of shares of the Company's common stock greater than the
"Total Shares Subject to Option" 



<PAGE>   10
indicated above. Notwithstanding anything herein to the contrary, this Option
shall expire on the Expiration Date set forth above and must be exercised, if at
all, on or before the Expiration Date; and provided further that this Option
must become exercisable as to at least 20% of the Shares for each full year
since the Date of Grant.

         3. RESTRICTION ON EXERCISE. This Option may not be exercised unless
such exercise is in compliance with the Securities Act and all applicable state
securities laws as they are in effect on the date of exercise, and the
requirements of any stock exchange or national market system on which the
Company's common stock may be listed at the time of exercise. Optionee
understands that the Company is under no obligation to register, qualify or list
the Shares with the SEC, any state securities commission or any stock exchange
to effect such compliance.

         4. TERMINATION OF OPTION. Except as provided below in this Section,
this Option shall terminate and may not be exercised if Optionee ceases to be
employed by the Company or any Parent or Subsidiary of the Company (or, in the
case of a nonqualified stock option, an Affiliate of the Company). Optionee
shall be considered to be employed by the Company for all purposes under Section
2 and this Section 4 if Optionee is an officer, director or full-time employee
of the Company or any Parent, Subsidiary or Affiliate of the Company or if the
Committee determines that Optionee is rendering substantial services as a
part-time employee, consultant or adviser to the Company or any Parent,
Subsidiary or Affiliate of the Company. The Committee shall have discretion to
determine whether Optionee has ceased to be employed by the Company or any
Parent, Subsidiary or Affiliate of the Company and the effective date on which
such employment terminated (the "Termination Date").

                  4.1 Termination Generally. If Optionee ceases to be employed
by the Company or any Parent, Subsidiary or Affiliate of the Company for any
reason except death or disability, this Option, to the extent (and only to the
extent) that it would have been exercisable by Optionee on the Termination Date,
may be exercised by Optionee within ninety (90) days after the Termination Date,
but in no event later than the Expiration Date.

                  4.2 Death or Disability. If Optionee's employment with the
Company or any Parent, Subsidiary or Affiliate of the Company is terminated
because of the death of Optionee or the disability of Optionee, this Option, to
the extent (and only to the extent) that it would have been exercisable by
Optionee on the Termination Date, may be exercised by Optionee (or Optionee's
legal representative) within twelve (12) months after the Termination Date, but
in no event later than the Expiration Date.

                  4.3 No Right to Employment. Nothing in the Plan or this Grant
shall confer on Optionee any right to continue in the employ of, or other
relationship with, the Company or any Parent, Subsidiary or Affiliate of the
Company or limit in any way the right of the Company or any Parent, Subsidiary
or Affiliate of the Company to terminate Optionee's employment or other
relationship at any time, with or without cause.

<PAGE>   11

         5.       MANNER OF EXERCISE.

                  5.1 Exercise Agreement. This Option shall be exercisable by
delivery to the Company of an executed written Stock Option Exercise Agreement
in the form attached hereto as Exhibit A, or in such other form as may be
approved by the Company, which shall set forth Optionee's election to exercise
some or all of this Option, the number of Shares being purchased, any
restrictions imposed on the Shares and such other representations and agreements
as may be required by the Company to comply with applicable securities laws.

                  5.2 Exercise Price. Such notice shall be accompanied by full
payment of the Exercise Price for the Shares being purchased. Payment for the
Shares may be made in cash (by check) or, where approved by the Committee in its
sole discretion and where permitted by law: (a) by cancellation of indebtedness
of the Company to Optionee; (b) by surrender of shares of common stock of the
Company having a Fair Market Value equal to the exercise price of the Option
that have been owned by Optionee for more than six (6) months (and which have
been paid for within the meaning of SEC Rule 144 and, if such Shares were
purchased from the Company by use of a promissory note, such note has been fully
paid with respect to such shares), or were obtained by Optionee in the open
public market; (c) by waiver of compensation due or accrued to Optionee for
services rendered; (d) provided that a public market for the Company's stock
exists, through a "same day sale" commitment from Optionee and a broker-dealer
that is a member of the National Association of Securities Dealers (an "NASD
Dealer") whereby Optionee irrevocably elects to exercise the Option and to sell
a portion of the Shares so purchased to pay for the Exercise Price and whereby
the NASD Dealer irrevocably commits upon receipt of such Shares to forward the
Exercise Price directly to the Company; (e) provided that a public market for
the Company's stock exists, through a "margin" commitment from Optionee and an
NASD Dealer whereby Optionee irrevocably elects to exercise the Option and to
pledge the Shares so purchased to the NASD Dealer in a margin account as
security for a loan from the NASD Dealer in the amount of the Exercise Price,
and whereby the NASD Dealer irrevocably commits upon receipt of such Shares to
forward the Exercise Price directly to the Company; or (f) by any combination of
the foregoing.

                  5.3 Withholding Taxes. Prior to the issuance of the Shares
upon exercise of this Option, Optionee must pay or make adequate provision for
any applicable federal or state withholding obligations of the Company.

                  5.4 Issuance of Shares. Provided that such notice and payment
are in form and substance satisfactory to counsel for the Company, the Company
shall cause the Shares to be issued in the name of Optionee, Optionee's legal
representative or Optionee's donee.

         6. NOTICE OF DISQUALIFYING DISPOSITION OF ISO SHARES. If the Option
granted to Optionee herein is an ISO, and if Optionee sells or otherwise
disposes of any of the Shares acquired pursuant to the ISO within (a) the date
two years after the Date of Grant, or (b) the date one year after exercise of
the ISO with respect to the Shares to be sold or disposed, Optionee shall
immediately notify the Company in writing of such disposition.



                                       3
<PAGE>   12

         7. NONTRANSFERABILITY OF OPTION. If this Option is an ISO, then this
Option may not be transferred in any manner other than by will or by the law of
descent and distribution and may be exercised during the lifetime of Optionee
only by Optionee. Otherwise, this Option may only be transferred (a) pursuant to
a qualified domestic relations order as defined by the Revenue Code or Title I
of the Employee Retirement Income Security Act, or the rules thereunder, or (b)
to Optionee's immediate family, to a trust for the benefit of Optionee or
Optionee's immediate family, or to a charitable entity qualified under Revenue
Code Section 501(c), where "immediate family" shall mean spouse, lineal
descendant or antecedent, brother or sister. The terms of this Option shall be
binding upon the executors, administrators, successors and assigns of Optionee.

         8. TAX CONSEQUENCES. Set forth below is a brief summary as of the date
this form of Grant was adopted of some of the federal and California tax
consequences of exercise of this Option and disposition of the Shares. THIS
SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT
TO CHANGE. OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION
OR DISPOSING OF THE SHARES.

                  8.1 Exercise of ISO. If this Option qualifies as an ISO, there
will be no regular federal income tax liability or California income tax
liability upon the exercise of the Option, although the excess, if any, of the
Fair Market Value of the Shares on the date of exercise over the Exercise Price
will be treated as an adjustment to alternative minimum taxable income for
federal income tax purposes and may subject Optionee to an alternative minimum
tax liability in the year of exercise.

                  8.2 Exercise of Nonqualified Stock Option. If this Option does
not qualify as an ISO, there may be a regular federal income tax liability and a
California income tax liability upon the exercise of the Option. Optionee will
be treated as having received compensation income (taxable at ordinary income
tax rates) equal to the excess, if any, of the Fair Market Value of the Shares
on the date of exercise over the Exercise Price. The Company will be required to
withhold from Optionee's compensation or collect from Optionee and pay to the
applicable taxing authorities an amount equal to a percentage of this
compensation income at the time of exercise.

                  8.3 Disposition of Shares. In the case of an NQSO, if Shares
are held for more than one year before disposition, any gain on disposition of
the Shares will be treated as long- term capital gain for federal and California
income tax purposes. In the case of an ISO, if Shares are held for more than one
year after the date of exercise and more than two years after the Date of Grant,
any gain on disposition on the Shares will be treated as long-term capital gain
for federal and California income tax purposes. If Shares acquired pursuant to
an ISO are disposed of within such one year or two year periods (a
"disqualifying disposition"), gain on such disqualifying disposition will be
treated as compensation income (taxable at ordinary income rates) to the extent
of the excess, if any, of the fair market value of the Shares on the date of
exercise over the Exercise Price (the "Spread"), or, if less, the difference
between the amount 



                                       4
<PAGE>   13

realized on the sale of such Shares and the Exercise Price. Any gain in excess
of the Spread shall be treated as capital gain.

         9. INTERPRETATION. Any dispute regarding the interpretation of this
Grant shall be submitted by Optionee or the Company to the Company's Board of
Directors or the Committee thereof that administers the Plan, which shall review
such dispute at its next regular meeting. The resolution of such a dispute by
the Board or Committee shall be final and binding on the Company and on
Optionee.

         10. ENTIRE AGREEMENT. The Plan and the Stock Option Exercise Agreement
attached as Exhibit A are incorporated herein by this reference. This Grant, the
Plan and the Stock Option Exercise Agreement constitute the entire agreement of
the parties hereto and supersede all prior undertakings and agreements with
respect to the subject matter hereof.

in all material respects on the date as of which such data, reports, and
information are dated or certified and not incomplete by omitting to state any

limit its operations to, the same general lines of business as those presently
conducted by it, and (d) comply with all applicable laws and regulations of any
federal, state, or local governmental authority, except for such laws and

<PAGE>   7
standard non-contributory "lender" or "secured party" clause and are to contain
such other provisions as the Lender may reasonably require to protect the
Lender's interests in the Collateral and to any payments to be made under such
policies. Certificates of insurance policies are to be delivered to the Lender,
premium prepaid, with the loss payable endorsement in the Lender's favor, and
shall provide for not less than thirty days' prior written notice to the Lender,
of any alteration or cancellation of coverage. If the Borrower fails to maintain

shall have the sole right, in the name of the Lender or the Borrower, to file
claims under any insurance policies, to receive and give acquittance for any

Borrower in accordance with GAAP. If any Taxes remain unpaid after the date
fixed for the payment thereof, or if any lien shall be claimed therefor, then,
without notice to the Borrower, but on the Borrower's behalf, the Lender may pay
such Taxes, and the amount thereof shall be included in the Obligations.

                      SECTION 5.6. BORROWER TO DEFEND COLLATERAL AGAINST CLAIMS;
FEES ON COLLATERAL. The Borrower will defend the Collateral against all claims

leasing, renting, possession, sale, or use of the Collateral, other than taxes
on or measured by the Lender's income and fees, assessments, charges, and taxes
which are being contested in good faith by appropriate proceedings diligently
conducted and with respect to which adequate reserves are maintained to the
extent required by GAAP.

                      SECTION 5.7. NO CHANGE OF LOCATION, STRUCTURE, OR

the Lender a first priority security interest in the Collateral. Notwithstanding
anything to the contrary in the immediately preceding sentence, the Borrower may
keep any Collateral consisting of motor vehicles or rolling stock at any
location in the United States provided that the Lender's security interest in
any such Collateral is conspicuously marked on the certificate of title thereof
and the Borrower has complied with the provisions of Section 5.9.

                      SECTION 5.8. USE OF COLLATERAL; LICENSES; REPAIR. The

written consent.

give any notices, execute and file any financing statements, mortgages, or other
documents (all in form and substance satisfactory to the Lender), mark any

any other actions that are necessary or, in the opinion of the Lender, desirable
to perfect or continue the perfection and the first priority of the Lender's
security interest in the Collateral, to protect the Collateral against the
rights, claims, or interests of any Persons, or to effect the purposes of this
Agreement. The Borrower hereby authorizes the Lender to file one or more
financing or continuation statements, and amendments thereto, relating to all or
any part of the Collateral without the signature of the Borrower where permitted
by law. A carbon, photographic, or other reproduction of this Agreement or any
financing statement covering the Collateral or any part thereof shall be
sufficient as a financing statement where permitted by law. To the extent
required under this Agreement, the Borrower will pay all costs incurred in
connection with any of the foregoing.

                      SECTION 5.10. NO DISPOSITION OF COLLATERAL. The Borrower
will not in any way hypothecate or create or permit to exist any lien, security
interest, charge, or encumbrance on or other interest in any of the Collateral,
except for the lien and security interest granted hereby and Permitted Liens
which are junior to the lien and security interest of the Lender, and the
Borrower will not sell, transfer, assign, pledge, collaterally assign, exchange,
or otherwise dispose of any of the Collateral other than in a de minimus
transaction in the ordinary course of business. In the event the Collateral, or
any part thereof, is sold, transferred, assigned, exchanged, or otherwise
disposed of in violation of these provisions, the security interest of the
Lender shall continue in such Collateral or part thereof notwithstanding such
sale, transfer, assignment, exchange, or other disposition, and the Borrower
will hold the proceeds thereof in a separate account for the benefit of the
Lender. Following such a sale, the Borrower will transfer such proceeds to the
Lender in kind.

                      SECTION 5.11. NO LIMITATION ON LENDER'S RIGHTS. The
Borrower will not enter into any contractual obligations which may restrict or
inhibit the Lender's rights or ability to sell or otherwise dispose of the
Collateral or any part thereof.

                      SECTION 5.12. PROTECTION OF COLLATERAL. Upon notice to the
Borrower (provided that if no Event of Default has occurred and is continuing
the Lender need not give any notice), the Lender shall have the right at any
time to make any payments and do any other acts the Lender may deem necessary to
protect its security interests in the Collateral, including, without limitation,
the rights to satisfy, purchase, contest, or compromise any encumbrance, charge,
or lien which, in the reasonable judgment of the Lender, appears to be prior to
or superior to the security interests granted hereunder, and appear in, and
defend any action or proceeding purporting to affect its security interests in,
or the value of, any of the Collateral. The Borrower hereby agrees to reimburse
the Lender for all payments made and expenses incurred to protect its rights
under this Agreement including reasonable fees, expenses, and disbursements of
attorneys and paralegals (including the allocated costs of in-house counsel)
acting for the Lender, including any of the foregoing payments under, or acts
taken to protect its security interests in, any of the Collateral, which amounts
shall be secured under this Agreement, and agrees it shall be bound by any
payment made or act taken by the Lender hereunder absent the Lender's gross
negligence or willful misconduct. The Lender shall have no obligation to make
any of the foregoing payments or perform any of the foregoing acts.

                      SECTION 5.13. DELIVERY OF ITEMS. The Borrower will (a)
promptly (but in no event later than three Business Days) after its receipt
thereof, deliver to the Lender any documents or certificates of title issued
with respect to any property included in the Collateral, and any promissory
notes, letters of credit or instruments related to or otherwise in connection
with any property included in the Collateral, which in any such

                                       8
<PAGE>   9
case come into the possession of the Borrower, or shall cause the issuer thereof
to deliver any of the same directly to the Lender, in each case with any
necessary endorsements in favor of the Lender and (b) deliver to the Lender as
soon as available copies of any and all press releases and other similar
communications issued by the Borrower.

                      SECTION 5.14. SOLVENCY. The Borrower shall be and remain
Solvent at all times.

                      SECTION 5.15. FUNDAMENTAL CHANGES. The Borrower shall not
(a) amend or modify its name, unless the Borrower delivers to the Lender thirty
days prior to any such proposed amendment or modification written notice of such
amendment or modification and within ten days before such amendment or
modification delivers executed Uniform Commercial Code financing statements (in
form and substance satisfactory to the Lender) or (b) merge or consolidate with
any other entity, in each case without the Lender's prior written consent which
shall not be unreasonably withheld.

                      SECTION 5.16. ADDITIONAL REQUIREMENTS. The Borrower shall
take all such further actions and execute all such further documents and
instruments as the Lender may reasonably request.


                  SECTION 6. FINANCIAL STATEMENTS. Until the payment and
satisfaction in full of all Obligations, the Borrower shall deliver to the
Lender the following financial information:

income statement, and statements of cash flows and shareholders equity for the
Borrower and its consolidated subsidiaries (the "Financial Statements") for such
year, reported on by independent certified public accountants without an adverse
qualification; and

                      SECTION 6.2. QUARTERLY FINANCIAL STATEMENTS. As soon as
available, but not later than 60 days after the end of each of the first three
fiscal quarters in any fiscal year of the Borrower and its consolidated
subsidiaries, the Financial Statements for such fiscal quarter, together with a
certification duly executed by a responsible officer of the Borrower that such
Financial Statements have been prepared in accordance with GAAP and are fairly
stated in all material respects (subject to normal year-end audit adjustments).

                  SECTION 7. EVENTS OF DEFAULT. The occurrence of any of the
following events shall constitute an Event of Default hereunder:

when due any amount required to be paid by the Borrower under or in connection
with any Note and this Agreement;

                      (b) any representation or warranty made or deemed made by

in this Section 7) and such failure remains unremedied for the earlier of
fifteen days from (A) the date on which the Lender has given the Borrower
written notice of such failure and (B) the date on which the Borrower knew or
should have known of such failure;

                      (d) any material provision of any Loan Document to which
the Borrower is a party shall for any reason cease to be valid and binding on
the Borrower, or the Borrower shall so state;

                      (e) dissolution, liquidation, winding up, or cessation of
the Borrower's business, failure of the Borrower generally to pay its debts as
they mature, admission in writing by the Borrower of its inability generally to
pay its debts as they mature, or calling of a meeting of the Borrower's
creditors for purposes of

                                       9

compromising any of the Borrower's debts;

                      (f) the commencement by or against the Borrower of any
bankruptcy, insolvency, arrangement, reorganization, receivership, or similar
proceedings under any federal or state law and, in the case of any such
involuntary proceeding, such proceeding remains undismissed or unstayed for
forty-five days following the commencement thereof, or any action by the
Borrower is taken authorizing any such proceedings;

                      (g) an assignment for the benefit of creditors is made by

                      (h) the Borrower shall default in (i) the payment of

agreement under which such indebtedness was created; or (ii) the observance or
performance of any other agreement or condition relating to any such
indebtedness or contained in any instrument or agreement relating thereto, or

other event or condition is to cause, or to permit the holder or holders of such
indebtedness to cause, with the giving of notice if required, such indebtedness
to become due prior to its stated maturity;

                      (i) the Borrower suffers or sustains a Material Adverse
Change;

                      (j) any tax lien, other than a Permitted Lien, is filed of

enforceable, or shall be determined to be unenforceable, in accordance with its
terms; the Borrower shall deny or disaffirm the Obligations under any of the
Loan Documents or any liens granted in connection therewith; or any liens

by this Agreement.


                  SECTION 8. REMEDIES. If any Event of Default shall have
occurred and be continuing:

                      (a) The Lender may, without prejudice to any of its other
rights under any Loan Document or Applicable Law, declare all Obligations to be
immediately due and payable (except with respect to any Event of Default set
forth in Section 7(f) hereof, in which case all Obligations shall automatically
become immediately due and payable without necessity of any declaration) without
presentment, representation, demand of payment, or protest, which are hereby
expressly waived.

                      (b) The Lender may take possession of the Collateral and,
for that purpose may enter, with the aid and assistance of any person or
persons, any premises where the Collateral or any part hereof is, or may be

                                       10
<PAGE>   11
                      (c) The obligation of the Lender, if any, to make
additional Loans or financial accommodations of any kind to the Borrower shall
immediately terminate.

                      (d) The Lender may exercise in respect of the Collateral,
in addition to other rights and remedies provided for herein (or in any Loan
Document) or otherwise available to it, all the rights and remedies of a secured
party under the applicable Uniform Commercial Code (the "Code") whether or not
the Code applies to the affected Collateral and also may (i) require the
Borrower to, and the Borrower hereby agrees that it will at its expense and upon
request of the Lender forthwith, assemble all or part of the Collateral as
directed by the Lender and make it available to the Lender at a place to be
designated by the Lender that is reasonably convenient to both parties and (ii)
without notice except as specified below, sell the Collateral or any part
thereof in one or more parcels at public or private sale, at any of the Lender's
offices or elsewhere, for cash, on credit, or for future delivery, and upon such
other terms as the Lender may deem commercially reasonable. The Borrower agrees
that, to the extent notice of sale shall be required by law, at least ten days'
notice to the Borrower of the time and place of any public sale or the time
after which any private sale is to be made shall constitute reasonable
notification. The Lender shall not be obligated to make any sale of Collateral
regardless of notice of sale having been given. The Lender may adjourn any
public or private sale from time to time by announcement at the time and place
fixed therefor, and such sale may, without further notice, be made at the time
and place to which it was so adjourned.

                      (e) All cash proceeds received by the Lender in respect of
any sale of, collection from, or other realization upon all or any part of the
Collateral may, in the discretion of the Lender, be held by the Lender as
collateral for, or then or at any time thereafter applied in whole or in part by
the Lender against, all or any part of the Obligations in such order as the
Lender shall elect. Any surplus of such cash or cash proceeds held by the Lender
and remaining after the full and final payment of all the Obligations shall be
paid over to the Borrower or to such other Person to which the Lender may be
required under applicable law, or directed by a court of competent jurisdiction,
to make payment of such surplus.

its assignee shall have delivered assignment documentation in form and substance
satisfactory to the Lender in its sole discretion. The Lender may assign its
rights and delegate its obligations under any Note or this Agreement.

                      SECTION 9.4. AMENDMENTS, WAIVERS, AND CONSENTS. Any

                      SECTION 9.5. INTERPRETATION OF AGREEMENT. Time is of the
essence in each provision of this Agreement of which time is an element. All
terms not defined herein or in a Note shall have the meaning set forth in the
applicable Code, except where the context otherwise requires. To the extent a
term or provision of this Agreement conflicts with any Note, or any term or
provision thereof, and is not dealt with herein with more specificity, this
Agreement shall control with respect to the subject matter of such term or
provision. Acceptance of or acquiescence in a course of performance rendered
under this Agreement shall not be relevant in determining the meaning of this

insolvency, bankruptcy, dissolution, liquidation, or reorganization of the
Borrower or upon the appointment of any receiver, intervenor, conservator,
trustee, or similar official for the Borrower or any substantial part of its
assets, or otherwise, all as though such payments had not been made.

                      SECTION 9.8. SURVIVAL OF PROVISIONS. All representations,
warranties, and covenants of the Borrower contained herein shall survive the
execution and delivery of this Agreement, and shall terminate only upon the full

employees, and counsel from and against any and all costs, expenses, claims, or
liability incurred by the Lender or such Person hereunder and under any other

liability shall be due to willful misconduct or gross negligence on the part of
the Lender or such Person.

                      SECTION 9.10. COUNTERPARTS; TELECOPIED SIGNATURES. This
Agreement may be executed in counterparts, each of which when so executed and

delivered by telecopier or other facsimile transmission all with the same force
and effect as if the same was a fully executed and delivered original manual
counterpart.

                      SECTION 9.11. SEVERABILITY. In case any provision in or
obligation under this Agreement or any Note or any other Loan Document shall be
invalid, illegal, or unenforceable in any jurisdiction, the validity, legality,
and enforceability of the remaining provisions or obligations, or of such
provision or obligation in any other jurisdiction, shall not in any way be
affected or impaired thereby.

                      SECTION 9.12. DELAYS; PARTIAL EXERCISE OF REMEDIES. No
delay or omission of the Lender to exercise any right or remedy hereunder,
whether before or after the happening of any Event of Default, shall impair any
such right or shall operate as a waiver thereof or as a waiver of any such Event
of Default. No single or partial exercise by the Lender of any right or remedy
shall preclude any other or further exercise thereof, or preclude any other
right or remedy.

AND ENFORCEMENT OF THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF ILLINOIS WITHOUT GIVING EFFECT TO THE
CONFLICT OF LAW PRINCIPLES THEREOF.

OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT MAY BE

         Re:      LXR Biotechnology, Inc.

Ladies and Gentlemen:

                  We have been asked by LXR Biotechnology, Inc., a Delaware
corporation (the "Company") to finance certain equipment (the "Equipment"),
which will be located at the address identified on Schedule A (the "Premises").
The obligations of the Company to us will be secured by, among other things, the
Equipment. We understand that the Company leases the Premises from you pursuant
to a lease or is the owner of the Premises, which is subject to a lien in favor
of you pursuant to a mortgage (such lease or mortgage being referred to as the
"Agreement").

                  In connection with the extensions of credit to be made to the
Company, Transamerica Business Credit Corporation, ("Transamerica") will be
making customary Uniform Commercial Code filings on behalf of Transamerica with
respect to the Equipment. In addition, we request your acknowledgment and
cooperation for preserving and enforcing Transamerica's security interests. To
expedite the consummation of the proposed financing, we would appreciate your
execution of this letter.

                  At the Company's request, to enable it to finance the
Equipment, and for other good and valuable consideration, you confirm and
acknowledge the following matters to us:

                  1. You will allow us, or our auditors or other designees,
reasonable access to the Premises to inspect the Equipment from time to time. In
addition, upon our request, during the term of the Agreement, you will grant us
and our designees access to the Premises for 90 days at reasonable times to show
the Equipment to potential purchasers and to remove the Equipment from the
Premises.

                  2. In the event that the Company defaults in its obligations
under the Agreement or you desire or elect to terminate or exercise remedies
under the Agreement for any reason, including a default by the Company under the
Agreement, you will notify us in writing of this fact prior to your terminating
or exercising remedies under the Agreement and retaking possession of the
Premises. You hereby confirm and acknowledge to us that you do not and will not
have any claim to or lien on any of the Equipment, whether such Equipment
constitutes fixtures or personal property.

                  We would appreciate your confirming to us your agreement to
the foregoing provisions of this letter by signing and returning to us this
letter at our address shown above.

Very truly yours,

                  This Note is one of the Notes referred to in the Security
Agreement dated as of May 13, 1997 (as amended, supplemented or otherwise
modified from time to time, the "Agreement"), between the undersigned and the
Payee and is subject and entitled to all provisions and benefits thereof.
Capitalized terms used but not defined herein shall have the meanings set forth
in the Agreement.

                  If any installment of this Note is not paid within five
business days after its due date, the undersigned agrees to pay on demand, in
addition to the amount of such installment, an amount equal to 5% of such
installment, but only to the extent permitted by Applicable Law.

                  The undersigned shall have the right to prepay this Note at
any time on thirty days' prior written notice to the Payee. On the date of any
such prepayment, the undersigned shall pay, if such prepayment is made on or

payments (principal and interest) due hereunder discounted at 6% simple interest
per annum, together with all interest, fees and other amounts payable on the
amount so prepaid or in connection therewith to the date of such prepayment. Any
prepayments shall be applied to the installments hereof in the inverse order of

maturity of this Note in accordance with the terms of the Agreement, the entire
unpaid principal amount on this Note, together with all interest, fees and other
amounts payable hereon or in connection herewith, shall be immediately due and
payable without further notice or demand, with interest on all such amounts at a
rate not to exceed the lawful limit, from the date of such maturity or
acceleration, as the case may be, until all such amounts have been paid.

than a Business Day, the maturity thereof shall be extended to the next
succeeding Business Day.

                  The undersigned hereby waives diligence, demand, presentment,
protest and notice of any kind, and assents to extensions of the time of
payment, release, surrender or substitution of security, or forbearance or other
indulgence, without notice. The undersigned agrees to pay all amounts under this
Note without offset, deduction, claim, counterclaim, defense or recoupment, all
of which are hereby waived.

                  The Payee, the undersigned and any other parties to the Loan
Documents intend to contract in strict compliance with applicable usury law from
time to time in effect. In furtherance thereof such Persons stipulate and agree
that none of the terms and provisions contained in the Loan Documents shall ever
be construed to create a contract to pay, for the use, forbearance or detention
of money, interest in excess of the maximum amount of interest permitted to be
charged by Applicable Law from time to time in effect. Neither the undersigned
nor any present or future guarantors, endorsers, or other Persons hereafter
becoming liable for payment of any
<PAGE>   17
Obligation shall ever be liable for unearned interest thereon or shall ever be
required to pay interest thereon in excess of the maximum amount that may be
lawfully charged under Applicable Law from time to time in effect, and the
provisions of this paragraph shall control over all other provisions of the Loan
Documents which may be in conflict or apparent conflict herewith. The Payee
expressly disavows any intention to charge or collect excessive unearned
interest or finance charges in the event the maturity of any Obligation is
accelerated. If (a) the maturity of any Obligation is accelerated for any
reason, (b) any Obligation is prepaid and as a result any amounts held to
constitute interest are determined to be in excess of the legal maximum, or (c)
the Payee or any other holder of any or all of the Obligations shall otherwise
collect amounts which are determined to constitute interest which would
otherwise increase the interest on any or all of the Obligations to an amount in
excess of that permitted to be charged by Applicable Law then in effect, then
all sums determined to constitute interest in excess of such legal limit shall,
without penalty, be promptly applied to reduce the then outstanding principal of
the related Obligations or, at the Payee's or such holder's option, promptly
returned to the undersigned upon such determination. In determining whether or
not the interest paid or payable, under any specific circumstance, exceeds the
maximum amount permitted under Applicable Law, the Payee and the undersigned
(and any other payors thereof) shall to the greatest extent permitted under
Applicable Law, (i) characterize any non-principal payment as an expense, fee or
premium rather than as interest, (ii) exclude voluntary prepayments and the
effects thereof, and (iii) amortize, prorate, allocate, and spread the total
amount of interest through the entire contemplated term of this Note in
accordance with the amount outstanding from time to time thereunder and the
maximum legal rate of interest from time to time in effect under Applicable Law
in order to lawfully charge the maximum amount of interest permitted under
Applicable Law.

                  This Note may not be changed, modified or terminated orally,
but only by an agreement in writing signed by the undersigned and the Payee or
any holder hereof.

                  The undersigned shall, upon demand, pay to the Payee all costs
and expenses paid or incurred by the Payee in (A) enforcing or defending its
rights under or in respect of this Note or any of the other Loan Documents, (B)
collecting any of the liabilities by the undersigned to the Payee or otherwise
administering the Loan Documents, (C) foreclosing or otherwise collecting upon
any collateral and (D) obtaining any legal, accounting or other advice in
connection with any of the foregoing.

                  This Note shall be binding upon the successors and assigns of
the undersigned and inure to the benefit of the Payee and its successors,
endorsees and assigns. If any term or provision of this Note shall be held
invalid, illegal or unenforceable, the validity of all other terms and
provisions hereof shall in no way be affected thereby.

                  EACH OF THE UNDERSIGNED AND, BY ITS ACCEPTANCE HEREOF, THE
PAYEE HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES (TO THE FULLEST
EXTENT PERMITTED BY APPLICABLE LAW) ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY OF
ANY DISPUTE ARISING UNDER OR RELATING TO THIS NOTE AND AGREES THAT ANY SUCH
DISPUTE SHALL BE TRIED BEFORE A JUDGE SITTING WITHOUT A JURY.

                  THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE
WITH THE LAWS OF THE STATE OF ILLINOIS WITHOUT GIVING EFFECT TO PRINCIPLES OF
CONFLICTS OF LAW.

                                 other amounts due and owing to Lender.

Interim Payments:                In the event that the Loan Term Commencement is
                                 not on the first day of the month, Interim

                                 warrants to purchase 27,000 shares of the
                                 common stock of the Borrower. The exercise
                                 price will be $2.1875 per share. The warrants
                                 will be exercisable from the date their
                                 issuance and have a term of 7 years. Lender

                                 dividends, reclassifications and exchanges, and
                                 will enjoy other rights no less favorable than
                                 the rights of any other holder of the
                                 Borrower's capital stock. The shares issuable  
                                 under each Warrant will have piggyback

                     LXR BIOTECHNOLOGY INC. (THE "COMPANY")

                     DATE OF INITIAL ISSUANCE: MAY 13, 1997

         THIS CERTIFIES THAT for value received, MEIER MITCHELL & COMPANY, LLC
or its registered assigns (hereinafter called the "Holder") is entitled to
purchase from the Company, at any time during the Term of this Warrant, Nine
Thousand (9,000) shares of common stock, $0.0001 par value, of the Company (the
"Common Stock"), at the Warrant Price, payable in lawful money of the United
States of America to be paid upon the exercise hereof. The exercise of this
Warrant shall be subject to the provisions, limitations and restrictions herein
contained, and may be exercised in whole or in part.

SECTION 1.  DEFINITIONS.

         For all purposes of this Warrant, the following terms shall have the
meanings indicated:

         COMMON STOCK - shall mean and include the Company's authorized Common
Stock, $0.0001 par value, as constituted at the date hereof.

         EXCHANGE ACT - shall mean the Securities Exchange Act of 1934, as
amended from time to time.

<PAGE>   2
         WARRANTS - this Warrant and any other Warrant or Warrants issued
pursuant to a Commitment Letter dated April 15, 1997 executed by the Company and
Transamerica Business Credit Corporation (the "Commitment Letter") to the
original holder of this Warrant, or any transferees from such original holder or
this Holder.

         WARRANT SHARES - shares of Common Stock purchased or purchasable by the
Holder of this Warrant upon the exercise hereof.

SECTION 2.  EXERCISE OF WARRANT.

         2.1. PROCEDURE FOR EXERCISE OF WARRANT. To exercise this Warrant in
whole or in part (but not as to any fractional share of Common Stock), the
Holder shall deliver to the Company at its office referred to in Section 12
hereof at any time and from time to time during the Term of this Warrant: (i)
the Notice of Exercise in the form attached hereto, (ii) cash, certified or
official bank check payable to the order of the Company, wire transfer of funds
to the Company's account, or evidence of any indebtedness of the Company to the
Holder (or any combination of any of the foregoing) in the amount of the Warrant
Price for each share being purchased, and (iii) this Warrant. Notwithstanding
any provisions herein to the contrary, if the Current Market Price (as defined
in Section 5) is greater than the Warrant Price (at the date of calculation, as
set forth below), in lieu of exercising this Warrant as hereinabove permitted,
the Holder may elect to receive shares of Common Stock equal to the value (as
determined below) of this Warrant (or the portion thereof being canceled) by
surrender of this Warrant at the office of the Company referred to in Section 12
hereof, together with the Notice of Exercise, in which event the Company shall
issue to the Holder that number of shares of Common Stock computed using the
following formula:

                               CS = WCS x (CMP-WP)
                                    --------------
                                       CMP

Where

         CS       equals the number of shares of Common Stock to be issued to
                  the Holder

         WCS      equals the number of shares of Common Stock purchasable under
                  the Warrant or, if only a portion of the Warrant is being
                  exercised, the portion of the Warrant being exercised (at the
                  date of such calculation)

         CMP      equals the Current Market Price (at the date of such
                  calculation)

         WP       equals the Warrant Price (as adjusted to the date of such
                  calculation)

In the event of any exercise of the rights represented by this Warrant, a
certificate or certificates for the shares of Common Stock so purchased,
registered in the name of the Holder or such other name or names as may be
designated by the Holder, shall be delivered to the Holder hereof within a
reasonable time, not exceeding fifteen (15) days, after the rights represented
by this Warrant shall have been so exercised; and, unless this Warrant has
expired, a new Warrant representing the number of shares (except a remaining
fractional share), if any, with respect to which this Warrant

                                     - 2 -
<PAGE>   3
shall not then have been exercised shall also be issued to the Holder hereof
within such time. The person in whose name any certificate for shares of Common
Stock is issued upon exercise of this Warrant shall for all purposes be deemed
to have become the holder of record of such shares on the date on which the
Warrant was surrendered and payment of the Warrant Price and any applicable
taxes was made, irrespective of the date of delivery of such certificate, except
that, if the date of such surrender and payment is a date when the stock
transfer books of the Company are closed, such person shall be deemed to have
become the holder of such shares at the close of business on the next succeeding
date on which the stock transfer books are open.

         2.2. TRANSFER RESTRICTION LEGEND. Each certificate for Warrant Shares
shall bear the following legend (and any additional legend required by (i) any
applicable state securities laws and (ii) any securities exchange upon which
such Warrant Shares may, at the time of such exercise, be listed) on the face
thereof unless at the time of exercise such Warrant Shares shall be registered
under the Securities Act:

         "The shares represented by this certificate have not been registered
         under the Securities Act of 1933, as amended, and may not be sold or
         transferred in the absence of such registration or an exemption
         therefrom under said Act."

Any certificate issued at any time in exchange or substitution for any
certificate bearing such legend (except a new certificate issued upon completion
of a public distribution under a registration statement of the securities
represented thereby) shall also bear such legend unless, in the opinion of
counsel for the holder thereof (which counsel shall be reasonably satisfactory
to counsel for the Company) the securities represented thereby are not, at such
time, required by law to bear such legend.

SECTION 3. COVENANTS AS TO COMMON STOCK. The Company covenants and agrees that
all shares of Common Stock that may be issued upon the exercise of the rights
represented by this Warrant will, upon issuance, be validly issued, fully paid
and nonassessable, and free from all taxes, liens and charges with respect to
the issue thereof. The Company further covenants and agrees that it will pay
when due and payable any and all federal and state taxes which may be payable in
respect of the issue of this Warrant or any Common Stock or certificates
therefor issuable upon the exercise of this Warrant. The Company further
covenants and agrees that the Company will at all times have authorized and
reserved, free from preemptive rights, a sufficient number of shares of Common
Stock to provide for the exercise of the rights represented by this Warrant. The
Company further covenants and agrees that if any shares of capital stock to be
reserved for the purpose of the issuance of shares upon the exercise of this
Warrant require registration with or approval of any governmental authority
under any federal or state law before such shares may be validly issued or
delivered upon exercise, then the Company will in good faith and as
expeditiously as possible endeavor to secure such registration or approval, as
the case may be. If and so long as the Common Stock issuable upon the exercise
of this Warrant is listed on any national securities exchange, the Company will,
if permitted by the rules of such exchange, list within a reasonable time after
the initial issuance of this Warrant and keep listed on such exchange, upon
official notice of issuance, all shares of such Common Stock issuable upon
exercise of this Warrant.

                                     - 3 -

SECTION 4. ADJUSTMENT OF NUMBER OF SHARES. Upon each adjustment of the Warrant
Price as provided in Section 5, the Holder shall thereafter be entitled to
purchase, at the Warrant Price resulting from such adjustment, the number of
shares (calculated to the nearest tenth of a share) obtained by multiplying the
Warrant Price in effect immediately prior to such adjustment by the number of
shares purchasable pursuant hereto immediately prior to such adjustment and
dividing the product thereof by the Warrant Price resulting from such
adjustment.

SECTION 5. ADJUSTMENT OF WARRANT PRICE. The Warrant Price shall be subject to
adjustment from time to time as follows:

         (i) If, at any time during the Term of this Warrant, the number of
shares of Common Stock outstanding is increased by a stock dividend payable in
shares of Common Stock or by a subdivision or split-up of shares of Common
Stock, then, following the record date fixed for the determination of holders of
Common Stock entitled to receive such stock dividend, subdivision or split-up,
the Warrant Price shall be appropriately decreased so that the number of shares
of Common Stock issuable upon the exercise hereof shall be increased in
proportion to such increase in outstanding shares.

         (ii) If, at any time during the Term of this Warrant, the number of
shares of Common Stock outstanding is decreased by a combination of the
outstanding shares of Common Stock, then, following the record date for such
combination, the Warrant Price shall appropriately increase so that the number
of shares of Common Stock issuable upon the exercise hereof shall be decreased
in proportion to such decrease in outstanding shares.

         (iii) In case, at any time during the Term of this Warrant, the Company
shall declare a cash dividend upon its Common Stock payable otherwise than out
of earnings or earned surplus or shall distribute to holders of its Common Stock
shares of its capital stock (other than Common Stock), stock or other securities
of other persons, evidences of indebtedness issued by the Company or other
persons, assets (excluding cash dividends and distributions) or options or
rights (excluding options to purchase and rights to subscribe for Common Stock
or other securities of the Company convertible into or exchangeable for Common
Stock), then, in each such case, immediately following the record date fixed for
the determination of the holders of Common Stock entitled to receive such
dividend or distribution, the Warrant Price in effect thereafter shall be
determined by multiplying the Warrant Price in effect immediately prior to such
record date by a fraction of which the numerator shall be an amount equal to the
difference of (x) the Current Market Price of one share of Common Stock minus
(y) the fair market value (as determined by the Board of Directors of the
Company, whose determination shall be conclusive) of the stock, securities,
evidences of indebtedness, assets, options or rights so distributed in respect
of one share of Common Stock, and of which the denominator shall be such Current
Market Price.

         (iv) All calculations under this Section 5 shall be made to the nearest
cent or to the nearest one-tenth (1/10) of a share, as the case may be.

         (v) For the purpose of any computation pursuant to this Section 5, the
Current Market Price at any date of one share of Common Stock shall be deemed to
be the average of the daily closing prices for the 15 consecutive business days
ending no more than 5 business days before the day in

                                     - 4 -

question (as adjusted for any stock dividend, split, combination or
reclassification that took effect during such 15 business day period). The
closing price for each day shall be the last reported sales price regular way
or, in case no such reported sales took place on such day, the average of the
last reported bid and asked prices regular way, in either case on the principal
national securities exchange on which the Common Stock is listed or admitted to
trading or as reported by Nasdaq (or if the Common Stock is not at the time
listed or admitted for trading on any such exchange or if prices of the Common
Stock are not reported by Nasdaq then such price shall be equal to the average
of the last reported bid and asked prices on such day as reported by The
National Quotation Bureau Incorporated or any similar reputable quotation and
reporting service, if such quotation is not reported by The National Quotation
Bureau Incorporated); provided, however, that if the Common Stock is not traded
in such manner that the quotations referred to in this clause (v) are available
for the period required hereunder, the Current Market Price shall be determined
in good faith by the Board of Directors of the Company or, if such determination
cannot be made, by a nationally recognized independent investment banking firm
selected by the Board of Directors of the Company (or if such selection cannot
be made, by a nationally recognized independent investment banking firm selected
by the American Arbitration Association in accordance with its rules).

         (vi) Whenever the Warrant Price shall be adjusted as provided in
Section 5, the Company shall prepare a statement showing the facts requiring
such adjustment and the Warrant Price that shall be in effect after such
adjustment. The Company shall cause a copy of such statement to be sent by mail,
first class postage prepaid, to each Holder of this Warrant at its, his or her
address appearing on the Company's records. Where appropriate, such copy may be
given in advance and may be included as part of the notice required to be mailed
under the provisions of subsection (viii) of this Section 5.

         (vii) Adjustments made pursuant to clauses (i), (ii) and (iii) above
shall be made on the date such dividend, subdivision, split-up, combination or
distribution, as the case may be, is made, and shall become effective at the
opening of business on the business day next following the record date for the
determination of stockholders entitled to such dividend, subdivision, split-up,
combination or distribution.

         (viii) In the event the Company shall propose to take any action of the
types described in clauses (i), (ii), or (iii) of this Section 5, the Company
shall forward, at the same time and in the same manner, to the Holder of this
Warrant such notice, if any, which the Company shall give to the holders of
capital stock of the Company.

         (ix) In any case in which the provisions of this Section 5 shall
require that an adjustment shall become effective immediately after a record
date for an event, the Company may defer until the occurrence of such event
issuing to the Holder of all or any part of this Warrant which is exercised
after such record date and before the occurrence of such event the additional
shares of capital stock issuable upon such exercise by reason of the adjustment
required by such event over and above the shares of capital stock issuable upon
such exercise before giving effect to such adjustment exercise; provided,
however, that the Company shall deliver to such Holder a due bill or other
appropriate instrument evidencing such Holder's right to receive such additional
shares upon the occurrence of the event requiring such adjustment.

SECTION 6.  OWNERSHIP.

         6.1. OWNERSHIP OF THIS WARRANT. The Company may deem and treat the
person in whose name this Warrant is registered as the holder and owner hereof
(notwithstanding any notations of ownership or writing hereon made by anyone
other than the Company) for all purposes and shall not be affected by any notice
to the contrary until presentation of this Warrant for registration of transfer
as provided in this Section 6.

         6.2. TRANSFER AND REPLACEMENT. Subject to compliance with applicable
securities laws, this Warrant and all rights hereunder are transferable in whole
or in part upon the books of the Company by the Holder hereof in person or by
duly authorized attorney, and a new Warrant or Warrants, of the same tenor as
this Warrant but registered in the name of the transferee or transferees (and in
the name of the Holder, if a partial transfer is effected) shall be made and
delivered by the Company upon surrender of this Warrant duly endorsed, at the
office of the Company referred to in Section 12 hereof. Upon receipt by the
Company of evidence reasonably satisfactory to it of the loss, theft or
destruction, and, in such case, of indemnity or security reasonably satisfactory
to it, and upon surrender of this Warrant if mutilated, the Company will make
and deliver a new Warrant of like tenor, in lieu of this Warrant; provided that
if the Holder hereof is an instrumentality of a state or local government or an
institutional holder or a nominee for such an instrumentality or institutional
holder an irrevocable agreement of indemnity by such Holder shall be sufficient
for all purposes of this Section 6, and no evidence of loss or theft or
destruction shall be necessary. This Warrant shall be promptly cancelled by the
Company upon the surrender hereof in connection with any transfer or
replacement. Except as otherwise provided above, in the case of the loss, theft
or destruction of a Warrant, the Company shall pay all expenses, taxes and other
charges payable in connection with any transfer or replacement of this Warrant,
other than stock transfer taxes (if any) payable in connection with a transfer
of this Warrant, which shall be payable by the Holder. Holder will not transfer
this Warrant and the rights hereunder except in compliance with federal and
state securities laws.

SECTION 7. MERGERS, CONSOLIDATION, SALES. In the case of any proposed
consolidation or merger of the Company with another entity, or the proposed sale
of all or substantially all of its assets to another person or entity, or any
proposed reorganization or reclassification of the capital stock of the Company,
then, as a condition of such consolidation, merger, sale, reorganization or
reclassification, lawful and adequate provision shall be made whereby the Holder
of this Warrant shall thereafter have the right to receive upon the basis and
upon the terms and conditions specified herein, in lieu of the shares of the
Common Stock of the Company immediately theretofore purchasable hereunder, such
shares of stock, securities or assets as may (by virtue of such consolidation,
merger, sale, reorganization or reclassification) be issued or payable with
respect to or in exchange for the number of shares of such Common Stock
purchasable hereunder immediately before such consolidation, merger, sale,
reorganization or reclassification. In any such case appropriate provision shall
be made with respect to the rights and interests of the Holder of this Warrant
to the end that the provisions hereof shall thereafter be applicable as nearly
as may be, in relation to any shares of stock, securities or assets thereafter
deliverable upon the exercise of this Warrant.

                                     - 6 -

SECTION 8. NOTICE OF DISSOLUTION OR LIQUIDATION. In case of any distribution of
the assets of the Company in dissolution or liquidation (except under
circumstances when the foregoing Section 7 shall be applicable), the Company
shall give notice thereof to the Holder hereof and shall make no distribution to
shareholders until the expiration of thirty (30) days from the date of mailing
of the aforesaid notice and, in any case, the Holder hereof may exercise this
Warrant within thirty (30) days from the date of the giving of such notice, and
all rights herein granted not so exercised within such thirty-day period shall
thereafter become null and void.

SECTION 9. NOTICE OF EXTRAORDINARY DIVIDENDS. If the Board of Directors of the
Company shall declare any dividend or other distribution on its Common Stock
except out of earned surplus or by way of a stock dividend payable in shares of
its Common Stock, the Company shall mail notice thereof to the Holder hereof not
less than thirty (30) days prior to the record date fixed for determining
shareholders entitled to participate in such dividend or other distribution, and
the Holder hereof shall not participate in such dividend or other distribution
unless this Warrant is exercised prior to such record date. The provisions of
this Section 9 shall not apply to distributions made in connection with
transactions covered by Section 7.

SECTION 10. FRACTIONAL SHARES. Fractional shares shall not be issued upon the
exercise of this Warrant but in any case where the Holder would, except for the
provisions of this Section 10, be entitled under the terms hereof to receive a
fractional share upon the complete exercise of this Warrant, the Company shall,
upon the exercise of this Warrant for the largest number of whole shares then
called for, pay a sum in cash equal to the excess of the value of such
fractional share (determined in such reasonable manner as may be prescribed in
good faith by the Board of Directors of the Company) over the Warrant Price for
such fractional share.

SECTION 11. SPECIAL ARRANGEMENTS OF THE COMPANY. The Company covenants and
agrees that during the Term of this Warrant, unless otherwise approved by the
Holder of this Warrant:

         11.1. WILL RESERVE SHARES. The Company will reserve and set apart and

received by the addressee.

SECTION 13. NO RIGHTS AS STOCKHOLDER; LIMITATION OF LIABILITY. This Warrant
shall not entitle the Holder to any of the rights of a shareholder of the
Company. No provision hereof, in the absence of affirmative action by the Holder
to purchase shares of Common Stock, and no mere enumeration herein of the rights
or privileges of the Holder, shall give rise to any liability of the Holder for
the Warrant Price hereunder or as a shareholder of the Company, whether such
liability is asserted by the Company or by creditors of the Company.

SECTION 14. LAW GOVERNING. THE VALIDITY, INTERPRETATION, AND ENFORCEMENT OF THIS
WARRANT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE

SECTION 15.  MISCELLANEOUS.

                  (a) This Warrant and any provision hereof may be changed,
waived, discharged or terminated only by an instrument in writing signed by the
party (or any predecessor in interest thereof) against which enforcement of the
same is sought. The headings in this Warrant are for purposes of reference only
and shall not affect the meaning or construction of any of the provisions hereof

                  (b) All capitalized terms used herein and not otherwise
defined herein shall have the meanings ascribed to them in the Financing
Agreement.


         IN WITNESS WHEREOF, the Company has caused this Warrant to be signed by
its duly authorized officer this 13th day of May, 1997.

                           STOCK SUBSCRIPTION WARRANT

                           TO PURCHASE COMMON STOCK OF

                     LXR BIOTECHNOLOGY INC. (THE "COMPANY")

                     DATE OF INITIAL ISSUANCE: MAY 13, 1997

         THIS CERTIFIES THAT for value received, TRANSAMERICA BUSINESS CREDIT
CORPORATION or its registered assigns (hereinafter called the "Holder") is
entitled to purchase from the Company, at any time during the Term of this
Warrant, Eighteen Thousand (18,000) shares of common stock, $0.0001 par value,
of the Company (the "Common Stock"), at the Warrant Price, payable in lawful
money of the United States of America to be paid upon the exercise hereof. The
exercise of this Warrant shall be subject to the provisions, limitations and
restrictions herein contained, and may be exercised in whole or in part.

SECTION 1.  DEFINITIONS.

         For all purposes of this Warrant, the following terms shall have the
meanings indicated:

         COMMON STOCK - shall mean and include the Company's authorized Common
Stock, $0.0001 par value, as constituted at the date hereof.

         EXCHANGE ACT - shall mean the Securities Exchange Act of 1934, as
amended from time to time.

         SECURITIES ACT - the Securities Act of 1933, as amended.

         TERM OF THIS WARRANT - shall mean the period beginning on the date of
initial issuance hereof and ending on May __, 2004.

         WARRANT PRICE - $2.1875 per share, subject to adjustment in accordance
with Section 5 hereof.
<PAGE>   2
         WARRANTS - this Warrant and any other Warrant or Warrants issued
pursuant to a Commitment Letter dated April 15, 1997 executed by the Company and
Transamerica Business Credit Corporation (the "Commitment Letter") to the
original holder of this Warrant, or any transferees from such original holder or
this Holder.

         WARRANT SHARES - shares of Common Stock purchased or purchasable by the
Holder of this Warrant upon the exercise hereof.

SECTION 2.  EXERCISE OF WARRANT.

         2.1. PROCEDURE FOR EXERCISE OF WARRANT. To exercise this Warrant in
whole or in part (but not as to any fractional share of Common Stock), the
Holder shall deliver to the Company at its office referred to in Section 12
hereof at any time and from time to time during the Term of this Warrant: (i)
the Notice of Exercise in the form attached hereto, (ii) cash, certified or
official bank check payable to the order of the Company, wire transfer of funds
to the Company's account, or evidence of any indebtedness of the Company to the
Holder (or any combination of any of the foregoing) in the amount of the Warrant
Price for each share being purchased, and (iii) this Warrant. Notwithstanding
any provisions herein to the contrary, if the Current Market Price (as defined
in Section 5) is greater than the Warrant Price (at the date of calculation, as
set forth below), in lieu of exercising this Warrant as hereinabove permitted,
the Holder may elect to receive shares of Common Stock equal to the value (as
determined below) of this Warrant (or the portion thereof being canceled) by
surrender of this Warrant at the office of the Company referred to in Section 12
hereof, together with the Notice of Exercise, in which event the Company shall
issue to the Holder that number of shares of Common Stock computed using the
following formula:

                               CS = WCS x (CMP-WP)
                                    --------------
                                       CMP

Where

         CS       equals the number of shares of Common Stock to be issued to
                  the Holder

         WCS      equals the number of shares of Common Stock purchasable under
                  the Warrant or, if only a portion of the Warrant is being
                  exercised, the portion of the Warrant being exercised (at the
                  date of such calculation)

         CMP      equals the Current Market Price (at the date of such
                  calculation)

         WP       equals the Warrant Price (as adjusted to the date of such
                  calculation)

In the event of any exercise of the rights represented by this Warrant, a
certificate or certificates for the shares of Common Stock so purchased,
registered in the name of the Holder or such other name or names as may be
designated by the Holder, shall be delivered to the Holder hereof within a
reasonable time, not exceeding fifteen (15) days, after the rights represented
by this Warrant shall have been so exercised; and, unless this Warrant has
expired, a new Warrant representing the number of shares (except a remaining
fractional share), if any, with respect to which this Warrant

                                     - 2 -
<PAGE>   3
shall not then have been exercised shall also be issued to the Holder hereof
within such time. The person in whose name any certificate for shares of Common
Stock is issued upon exercise of this Warrant shall for all purposes be deemed
to have become the holder of record of such shares on the date on which the
Warrant was surrendered and payment of the Warrant Price and any applicable
taxes was made, irrespective of the date of delivery of such certificate, except
that, if the date of such surrender and payment is a date when the stock
transfer books of the Company are closed, such person shall be deemed to have
become the holder of such shares at the close of business on the next succeeding
date on which the stock transfer books are open.

         2.2. TRANSFER RESTRICTION LEGEND. Each certificate for Warrant Shares
shall bear the following legend (and any additional legend required by (i) any
applicable state securities laws and (ii) any securities exchange upon which
such Warrant Shares may, at the time of such exercise, be listed) on the face
thereof unless at the time of exercise such Warrant Shares shall be registered
under the Securities Act:

         "The shares represented by this certificate have not been registered
         under the Securities Act of 1933, as amended, and may not be sold or
         transferred in the absence of such registration or an exemption
         therefrom under said Act."

Any certificate issued at any time in exchange or substitution for any
certificate bearing such legend (except a new certificate issued upon completion
of a public distribution under a registration statement of the securities
represented thereby) shall also bear such legend unless, in the opinion of
counsel for the holder thereof (which counsel shall be reasonably satisfactory
to counsel for the Company) the securities represented thereby are not, at such
time, required by law to bear such legend.

SECTION 3. COVENANTS AS TO COMMON STOCK. The Company covenants and agrees that
all shares of Common Stock that may be issued upon the exercise of the rights
represented by this Warrant will, upon issuance, be validly issued, fully paid
and nonassessable, and free from all taxes, liens and charges with respect to
the issue thereof. The Company further covenants and agrees that it will pay
when due and payable any and all federal and state taxes which may be payable in
respect of the issue of this Warrant or any Common Stock or certificates
therefor issuable upon the exercise of this Warrant. The Company further
covenants and agrees that the Company will at all times have authorized and
reserved, free from preemptive rights, a sufficient number of shares of Common
Stock to provide for the exercise of the rights represented by this Warrant. The
Company further covenants and agrees that if any shares of capital stock to be
reserved for the purpose of the issuance of shares upon the exercise of this
Warrant require registration with or approval of any governmental authority
under any federal or state law before such shares may be validly issued or
delivered upon exercise, then the Company will in good faith and as
expeditiously as possible endeavor to secure such registration or approval, as
the case may be. If and so long as the Common Stock issuable upon the exercise
of this Warrant is listed on any national securities exchange, the Company will,
if permitted by the rules of such exchange, list within a reasonable time after
the initial issuance of this Warrant and keep listed on such exchange, upon
official notice of issuance, all shares of such Common Stock issuable upon
exercise of this Warrant.

                                     - 3 -
<PAGE>   4
SECTION 4. ADJUSTMENT OF NUMBER OF SHARES. Upon each adjustment of the Warrant
Price as provided in Section 5, the Holder shall thereafter be entitled to
purchase, at the Warrant Price resulting from such adjustment, the number of
shares (calculated to the nearest tenth of a share) obtained by multiplying the
Warrant Price in effect immediately prior to such adjustment by the number of
shares purchasable pursuant hereto immediately prior to such adjustment and
dividing the product thereof by the Warrant Price resulting from such
adjustment.

SECTION 5. ADJUSTMENT OF WARRANT PRICE. The Warrant Price shall be subject to
adjustment from time to time as follows:

         (i) If, at any time during the Term of this Warrant, the number of
shares of Common Stock outstanding is increased by a stock dividend payable in
shares of Common Stock or by a subdivision or split-up of shares of Common
Stock, then, following the record date fixed for the determination of holders of
Common Stock entitled to receive such stock dividend, subdivision or split-up,
the Warrant Price shall be appropriately decreased so that the number of shares
of Common Stock issuable upon the exercise hereof shall be increased in
proportion to such increase in outstanding shares.

         (ii) If, at any time during the Term of this Warrant, the number of
shares of Common Stock outstanding is decreased by a combination of the
outstanding shares of Common Stock, then, following the record date for such
combination, the Warrant Price shall appropriately increase so that the number
of shares of Common Stock issuable upon the exercise hereof shall be decreased
in proportion to such decrease in outstanding shares.

         (iii) In case, at any time during the Term of this Warrant, the Company
shall declare a cash dividend upon its Common Stock payable otherwise than out
of earnings or earned surplus or shall distribute to holders of its Common Stock
shares of its capital stock (other than Common Stock), stock or other securities
of other persons, evidences of indebtedness issued by the Company or other
persons, assets (excluding cash dividends and distributions) or options or
rights (excluding options to purchase and rights to subscribe for Common Stock
or other securities of the Company convertible into or exchangeable for Common
Stock), then, in each such case, immediately following the record date fixed for
the determination of the holders of Common Stock entitled to receive such
dividend or distribution, the Warrant Price in effect thereafter shall be
determined by multiplying the Warrant Price in effect immediately prior to such
record date by a fraction of which the numerator shall be an amount equal to the
difference of (x) the Current Market Price of one share of Common Stock minus
(y) the fair market value (as determined by the Board of Directors of the
Company, whose determination shall be conclusive) of the stock, securities,
evidences of indebtedness, assets, options or rights so distributed in respect
of one share of Common Stock, and of which the denominator shall be such Current
Market Price.

         (iv) All calculations under this Section 5 shall be made to the nearest
cent or to the nearest one-tenth (1/10) of a share, as the case may be.

         (v) For the purpose of any computation pursuant to this Section 5, the
Current Market Price at any date of one share of Common Stock shall be deemed to
be the average of the daily closing prices for the 15 consecutive business days
ending no more than 5 business days before the day in

                                     - 4 -
<PAGE>   5
question (as adjusted for any stock dividend, split, combination or
reclassification that took effect during such 15 business day period). The
closing price for each day shall be the last reported sales price regular way
or, in case no such reported sales took place on such day, the average of the
last reported bid and asked prices regular way, in either case on the principal
national securities exchange on which the Common Stock is listed or admitted to
trading or as reported by Nasdaq (or if the Common Stock is not at the time
listed or admitted for trading on any such exchange or if prices of the Common
Stock are not reported by Nasdaq then such price shall be equal to the average
of the last reported bid and asked prices on such day as reported by The
National Quotation Bureau Incorporated or any similar reputable quotation and
reporting service, if such quotation is not reported by The National Quotation
Bureau Incorporated); provided, however, that if the Common Stock is not traded
in such manner that the quotations referred to in this clause (v) are available
for the period required hereunder, the Current Market Price shall be determined
in good faith by the Board of Directors of the Company or, if such determination
cannot be made, by a nationally recognized independent investment banking firm
selected by the Board of Directors of the Company (or if such selection cannot
be made, by a nationally recognized independent investment banking firm selected
by the American Arbitration Association in accordance with its rules).

         (vi) Whenever the Warrant Price shall be adjusted as provided in
Section 5, the Company shall prepare a statement showing the facts requiring
such adjustment and the Warrant Price that shall be in effect after such
adjustment. The Company shall cause a copy of such statement to be sent by mail,
first class postage prepaid, to each Holder of this Warrant at its, his or her
address appearing on the Company's records. Where appropriate, such copy may be
given in advance and may be included as part of the notice required to be mailed
under the provisions of subsection (viii) of this Section 5.

         (vii) Adjustments made pursuant to clauses (i), (ii) and (iii) above
shall be made on the date such dividend, subdivision, split-up, combination or
distribution, as the case may be, is made, and shall become effective at the
opening of business on the business day next following the record date for the
determination of stockholders entitled to such dividend, subdivision, split-up,
combination or distribution.

         (viii) In the event the Company shall propose to take any action of the
types described in clauses (i), (ii), or (iii) of this Section 5, the Company
shall forward, at the same time and in the same manner, to the Holder of this
Warrant such notice, if any, which the Company shall give to the holders of
capital stock of the Company.

         (ix) In any case in which the provisions of this Section 5 shall
require that an adjustment shall become effective immediately after a record
date for an event, the Company may defer until the occurrence of such event
issuing to the Holder of all or any part of this Warrant which is exercised
after such record date and before the occurrence of such event the additional
shares of capital stock issuable upon such exercise by reason of the adjustment
required by such event over and above the shares of capital stock issuable upon
such exercise before giving effect to such adjustment exercise; provided,
however, that the Company shall deliver to such Holder a due bill or other
appropriate instrument evidencing such Holder's right to receive such additional
shares upon the occurrence of the event requiring such adjustment.

SECTION 6.  OWNERSHIP.

         6.1. OWNERSHIP OF THIS WARRANT. The Company may deem and treat the
person in whose name this Warrant is registered as the holder and owner hereof
(notwithstanding any notations of ownership or writing hereon made by anyone
other than the Company) for all purposes and shall not be affected by any notice
to the contrary until presentation of this Warrant for registration of transfer
as provided in this Section 6.

         6.2. TRANSFER AND REPLACEMENT. Subject to compliance with applicable
securities laws, this Warrant and all rights hereunder are transferable in whole
or in part upon the books of the Company by the Holder hereof in person or by
duly authorized attorney, and a new Warrant or Warrants, of the same tenor as
this Warrant but registered in the name of the transferee or transferees (and in
the name of the Holder, if a partial transfer is effected) shall be made and
delivered by the Company upon surrender of this Warrant duly endorsed, at the
office of the Company referred to in Section 12 hereof. Upon receipt by the
Company of evidence reasonably satisfactory to it of the loss, theft or
destruction, and, in such case, of indemnity or security reasonably satisfactory
to it, and upon surrender of this Warrant if mutilated, the Company will make
and deliver a new Warrant of like tenor, in lieu of this Warrant; provided that
if the Holder hereof is an instrumentality of a state or local government or an
institutional holder or a nominee for such an instrumentality or institutional
holder an irrevocable agreement of indemnity by such Holder shall be sufficient
for all purposes of this Section 6, and no evidence of loss or theft or
destruction shall be necessary. This Warrant shall be promptly cancelled by the
Company upon the surrender hereof in connection with any transfer or
replacement. Except as otherwise provided above, in the case of the loss, theft
or destruction of a Warrant, the Company shall pay all expenses, taxes and other
charges payable in connection with any transfer or replacement of this Warrant,
other than stock transfer taxes (if any) payable in connection with a transfer
of this Warrant, which shall be payable by the Holder. Holder will not transfer
this Warrant and the rights hereunder except in compliance with federal and
state securities laws.

SECTION 7. MERGERS, CONSOLIDATION, SALES. In the case of any proposed
consolidation or merger of the Company with another entity, or the proposed sale
of all or substantially all of its assets to another person or entity, or any
proposed reorganization or reclassification of the capital stock of the Company,
then, as a condition of such consolidation, merger, sale, reorganization or
reclassification, lawful and adequate provision shall be made whereby the Holder
of this Warrant shall thereafter have the right to receive upon the basis and
upon the terms and conditions specified herein, in lieu of the shares of the
Common Stock of the Company immediately theretofore purchasable hereunder, such
shares of stock, securities or assets as may (by virtue of such consolidation,
merger, sale, reorganization or reclassification) be issued or payable with
respect to or in exchange for the number of shares of such Common Stock
purchasable hereunder immediately before such consolidation, merger, sale,
reorganization or reclassification. In any such case appropriate provision shall
be made with respect to the rights and interests of the Holder of this Warrant
to the end that the provisions hereof shall thereafter be applicable as nearly
as may be, in relation to any shares of stock, securities or assets thereafter
deliverable upon the exercise of this Warrant.

shareholders until the expiration of thirty (30) days from the date of mailing
of the aforesaid notice and, in any case, the Holder hereof may exercise this
Warrant within thirty (30) days from the date of the giving of such notice, and

less than thirty (30) days prior to the record date fixed for determining
shareholders entitled to participate in such dividend or other distribution, and
the Holder hereof shall not participate in such dividend or other distribution
unless this Warrant is exercised prior to such record date. The provisions of
this Section 9 shall not apply to distributions made in connection with
transactions covered by Section 7.

SECTION 10. FRACTIONAL SHARES. Fractional shares shall not be issued upon the
exercise of this Warrant but in any case where the Holder would, except for the
provisions of this Section 10, be entitled under the terms hereof to receive a
fractional share upon the complete exercise of this Warrant, the Company shall,
upon the exercise of this Warrant for the largest number of whole shares then
called for, pay a sum in cash equal to the excess of the value of such
fractional share (determined in such reasonable manner as may be prescribed in
good faith by the Board of Directors of the Company) over the Warrant Price for
such fractional share.

agrees that during the Term of this Warrant, unless otherwise approved by the

shall not entitle the Holder to any of the rights of a shareholder of the

                  and will comply with all applicable laws and regulations.

         2.5      OA shall ensure that all OA's Personnel involved with the
                  Services are technically competent and suitably qualified to
                  carry out the parts of the Services assigned to them.

         2.6      OA shall appoint Dr. Tony Baxter as Programme Manager together
                  with the LXR Dedicated Team and LXR shall appoint Dr. Graham
                  Goddard as Designated Supervisor for the Research Programme.
                  The Programme Manager and the Designated Supervisor shall be
                  the principal point of contact between the parties for all
                  matters relating to this Agreement. OA may change the
                  Programme Manager and the LXR Dedicated Team and LXR may
                  change the Designated Supervisor by giving notice in writing
                  to the other party.

         2.7      No variation to the Services shall be made without the written
                  agreement of the duly authorized representative of each Party
                  to such variation.


3.       INFORMATION AND REPORTS

         3.1      OA shall keep LXR fully informed of the progress of the
                  Services by providing progress reports to the Designated
                  Supervisor at the end of each month until the Services are
                  completed.

         3.2      OA shall ensure the Programme Manager is reasonably available
                  for telephone and face-to-face discussions with LXR's
                  Personnel. If LXR requests the LXR Dedicated Team to attend
                  any meetings other than those on OA premises, in addition to
                  those sums specified in Appendix B, OA shall be reimbursed for
                  reasonable travel expenses. If LXR requests OA Personnel other

                                             ** Confidential Treatment Requested


                  than the LXR Dedicated Team to attend meetings other than
                  those on OA premises, OA shall be reimbursed for reasonable
                  travel expenses and be paid at OA's standard time charge rates
                  for such expenses incurred and time spent by OA Personnel
                  attending any such meetings.

4.       INVOICES AND PAYMENT

         4.1      When due, OA shall submit an invoice to LXR for each of the
                  payments in accordance with Appendix B together with such
                  documentary substantiation as LXR may reasonably request.

         4.2      LXR shall pay OA's invoices within 30 days of invoice date.

         4.3      In the event that LXR fails to pay OA's invoices within 30
                  days of the invoice date OA shall be entitled to suspend
                  performance of the Services until OA receives the sums due
                  plus interest at the rate of 1.5% per month or part thereof in
                  respect of the period by which LXR is late in making payment.
                  Following suspension of performance of the Services for this
                  reason OA may vary any subsequent dates in the Research
                  Programme and/or the date for completion of the Services
                  specified in clause 2.3.


5.       RIGHT TO EXPLOIT THE "PRODUCTS"

         5.1      LXR and/or any of its Affiliates shall have the right to
                  develop and/or patent any Product supplied under this
                  Agreement (or any analogue or derivative of any Product
                  conceived as a result of screening or testing a Product) as a
                  potential product within the Field of Use. In such
                  circumstances, LXR shall notify OA in writing of its intention
                  to develop and/or patent such Product (or analogue/derivative
                  thereof) and the potential application. OA hereby undertakes
                  to execute and do all things necessary to vest the title and
                  interest in such Products (together with the Intellectual
                  Property Rights relating thereto) in LXR.

         5.2      In the event that LXR develops any Product (or
                  analogue/derivative thereof) and a member of OA's Personnel
                  would be considered as an inventor of the Product (or
                  analogue/derivative thereof) under the law of inventorship as
                  set forth under the laws of the United States, LXR shall pay
                  to OA a royalty on net sales of such Product equal to [**];
                  provided that such Product (or analogue/derivative thereof) is
                  patentable and was not claimed in a United States patent
                  application filed by LXR or its Affiliates with a priority
                  date on or before April 21, 1997. In the event that the
                  Product (or analogue/derivative thereof) is not patentable LXR
                  shall pay to OA a royalty on net sales of such Product equal
                  to [**]. Such royalties shall be the subject of a definitive
                  agreement between OA and LXR which will include other clauses
                  and provisions typical in similar agreements between similar
                  parties.

         5.3      Where OA has Intellectual Property Rights related to the
                  method of making or the composition of matter of any Product
                  for which it receives notice under Clause 5.1, OA shall grant
                  to LXR a license under any such Intellectual Property Rights
                  owned by OA (and in respect of which OA is free to grant such
                  license) to the extent that such license is necessary to
                  enable LXR to make, use, offer to sell, sell or import such
                  Product (or analogue/derivative thereof).


6.       INTELLECTUAL PROPERTY RIGHTS

         6.1      It is hereby expressly agreed that the Parties shall each
                  retain all Intellectual Property Rights relating to the
                  Products that they respectively hold prior to the date of this
                  Agreement, including without limitation all patent
                  applications and other forms of patent protection undertaken
                  by the Parties in respect of the Products prior to the date of
                  this Agreement.

         6.2      All Intellectual Property Rights relating to the use of the
                  Products in the Field of Use shall vest in LXR.
<PAGE>   4
         6.3      All Intellectual Property Rights relating to chemical
                  processes and technology used to synthesize the Products
                  arising from the performance of the Services shall vest in OA.

         6.4      All Intellectual Property Rights relating to composition of
                  matter and application claims outside the field of human
                  pharmaceuticals for compounds arising from the performance of
                  the Services shall be jointly owned by the Parties.

         6.5      It is hereby agreed between the parties that if OA or any of
                  its Affiliates wish to file a patent application in respect of
                  a Product after the date of this Agreement, OA shall
                  immediately notify LXR in writing and the Parties shall meet
                  to discuss the patent protection to be applied for.

         6.6      It is hereby further agreed that, unless agreed between the
                  Parties in writing, LXR shall at its sole option have the
                  right to patent the Products within the Field of Use.

         6.7      OA hereby agrees that it shall take no action (which includes,
                  for the avoidance of doubt, the filing of any patent
                  applications in respect of Products provided to LXR under this
                  Agreement, and which fall within the Field of Use) which would
                  have the effect of frustrating LXR's ability to develop
                  Products and apply for patents in the manner contemplated in
                  Clause 5.1.

         6.8      Subject to the agreement of LXR to compensate OA for any loss
                  arising from the disclosure of any Technical Information which
                  is valuable for purposes not covered by the royalty
                  arrangement described in clause 5.2, and which is identified
                  as such by OA, and which is made public in connection with
                  this clause, at the written request and expense of LXR, OA
                  shall, and shall procure that OA's Personnel shall, do all
                  things reasonably requested by LXR to apply for and obtain
                  effective patent protection anywhere in the world in respect
                  of any invention arising from the performance of the Services
                  including the execution of appropriate documents. For the
                  avoidance of doubt, LXR shall reimburse OA for all reasonable
                  costs incurred by OA and shall pay OA at OA's standard time
                  charge rates for time spent by OA Personnel in complying with
                  the provisions of this clause.

                                    legally binding confidentiality obligations
                                    substantially similar in scope to those set
                                    out in this clause 7;

                           (ii)     not use any Confidential Information for any
                                    purpose other than in accordance with this
                                    Agreement; and

                  the same may be used in and/or arise from the performance of
                  the Services.

                  shall not include any information which:-

                           (i)      is in the public domain other than through
                                    any breach of this Agreement;

                           (ii)     either Party can prove by documentary

                          expenses) incurred by OA which arise directly out of
                          any claim or allegation that performance of the

                                    1,000,000 per claim or series of claims.
