               respectively use reasonable efforts to provide the other in a

               must be signed by both parties to authorize implementation of any
               such changes. In addition, if any such change would substantially
               affect the economics of Incyte's performance, then: i) any dates
               or time periods relevant to performance by Incyte hereunder,
               shall be appropriately and equitably extended to account for any
               delays resulting from such changes, and ii) the parties will

               to Incyte in accordance with a reasonable proposal from Incyte
               with respect to such changes.

4.4  CUSTOMER Proprietary Data. Any proprietary data of CUSTOMER added to
     LifeArray(R) Products (i.e. non-Incyte data) by CUSTOMER, CUSTOMER
     Affiliate or consultant(s) (as provided for in Section 3.3.5
     (Modifications), above) shall remain the sole property of CUSTOMER and
     Incyte shall have no ownership rights to data.

                           5.0 SCHEDULE OF PAYMENTS.

5.1  License Fees: During the Access Term and for each additional Installation
     Site, yearly license fees with respect to the LifeArray(TM) Product(s)
     shall be payable by CUSTOMER on the following schedule:

     5.1.1 Access Term Fees. During the Access Term, CUSTOMER shall pay to
     Incyte yearly license fees of seventy-five thousand dollars (US$75,000) per
     year. The first payment of seventy five thousand dollars (US$75,000) shall
     be due and payable within thirty (30) days of the Effective Date. In the
     event CUSTOMER has extended the Access Term, the second payment of seventy
     five thousand dollars (US$75,000) shall be due and payable on or before the
     first anniversary of the Effective Date.

     5.1.2 Additional Installation Site. With respect to the designation of an
     additional Installation Site, after payment for that additional
     Installation Site of the License Payment specified in Section 5.1 (License
     Payment), the corresponding yearly Access Term Fees for such additional
     Installation Site shall be prorated for the remainder of such year of the
     Access Term.

5.2  Consulting Services. At CUSTOMER'S written request, the following
     consulting services may be provided to CUSTOMER by Incyte at the additional
     fees provided for below:

          (a) With respect to consulting services in excess of the time
          necessary for installation of LifeArray(TM) Product(s) or the
          Integration Project(s) as set forth in Sections 2.1 (Installation) and
          2.2 (Integration Program), CUSTOMER shall pay Incyte on a time and
          materials basis at a rate of $2,000 per-person-day plus expenses.

          (b) Payments shall be due in arrears within thirty (30) days receipt
          of invoice from Incyte in reasonably detailed form. All other expenses
          incurred by CUSTOMER or Incyte or their respective personnel in
          connection with Integration Project shall be the responsibility of
          each respective Party.

          (c) Incyte agrees to keep records of its costs associated with the
          consulting services performed by Incyte in sufficient detail to permit
          CUSTOMER to confirm the accuracy of Incyte's time and materials
          calculations. At the request and the expense of CUSTOMER (but no more
          than once a year), upon at least five (5) business days prior written
          notice to Incyte, Incyte shall permit a


                                       11
<PAGE>   13
        nationally recognized, independent, certified public accountant
        appointed by CUSTOMER and reasonably acceptable to Incyte, to examine
        such records solely to the extent necessary to verify the amount of
        payments due to Incyte hereunder, provided that such accountant has
        entered into a confidentiality agreement with Incyte substantially
        similar to the confidentiality provisions of this agreement, limiting
        the use and disclosure of such information to purposes germane hereto.
        Such accountant shall solely disclose to CUSTOMER whether or not an
        accounting discrepancy was found and the extent of such discrepancy,
        however, the results of any such examination shall be made available to
        both parties. If the examination reveals an overpayment by CUSTOMER to
        Incyte of project costs, then the amount of such overpayment will be
        refunded to CUSTOMER by Incyte. If the examination reveals an
        underpayment by CUSTOMER to Incyte of project costs, then the amount of
        such underpayment shall be paid by CUSTOMER to Incyte. Any refund or
        payment under this Section 5.3(c), shall be made to the appropriate
        Party within thirty (30) days of the date CUSTOMER delivers to Incyte
        such accountant's written report.

5.3  Payments and Taxes.

        (a) Unless otherwise provided for in this Agreement, CUSTOMER agrees to
        submit payments for services and materials provided by Incyte within
        thirty (30) days from receipt of an invoice from Incyte. All payments
        shall be made by check or bank wire transfer in immediately available
        funds to such account as Incyte shall designate before such payment is
        due, free and clear of any taxes, duties, levies, fees or charges.
        CUSTOMER shall pay and indemnify Incyte against any sales, use, value
        added/ad valorum, surtax and personal property taxes, customs, duties,
        registration fees and the like, including penalties and interest, levied
        by any governmental authority, (other than taxes based upon Incyte's net
        income) arising out of this Agreement and the transactions contemplated
        herein, including the costs and responsibility of any withholding taxes
        as below.

        (b) CUSTOMER shall make any withholding payments due on behalf of Incyte
        and shall promptly provide Incyte with written documentation of any such
        payment made on behalf of Incyte. Such written documentation shall be
        sufficiently detailed so as to satisfy any requirements of the United
        States Internal Revenue Service, or foreign government, as applicable,
        related to an application by Incyte for a foreign tax credit or refund
        for such payment to the extent applicable. However, in the case where
        Incyte can apply for and actually receives a credit or refund against
        its tax liability for the withholding payments due on behalf of Incyte
        and made by CUSTOMER, then such credited or refunded withholding payment
        will be reimbursed by Incyte to CUSTOMER. The parties agree to take
        reasonable and lawful steps to minimize the amount of tax to which
        payments to Incyte are subject.

                                       12
<PAGE>   14
               (c) All payments due Incyte under this Agreement may be
               creditable against any balance of the Five Million Dollars
               (US$5,000,000) due Incyte for sequencing and other services.

5.4     Late Payments. Any amounts payable hereunder that are not paid when due,
        shall bear interest to the extent permitted by applicable law, at two
        percentage points over the prime rate of interest as reported by Bank
        of America NT&SA in San Francisco, California, from time to time,
        calculated on the number of days such payment is delinquent.

5.5     Shipping. CUSTOMER shall pay, for its own account, any shipping,
        freight, mailing expenses and the like payable to third parties not
        affiliated with Incyte and arising out of obtaining tangible materials
        under this Agreement and the transactions contemplated herein.

5.6     Miscellaneous Payments. Unless otherwise provided in this Agreement,
        neither Party shall provide services or information to the other on a
        chargeable basis without the prior written agreement of the other
        Party, with regard to such services or information as well as to the
        charges and payment schedules therefor.


                              6.0 CONFIDENTIALITY

6.1     Confidentiality. The Parties acknowledge that during the course of this
        Agreement they will each receive from the other information which is
        proprietary, confidential and of commercial value to the disclosing
        Party. For purposes of this Agreement, "Confidential Information" shall
        mean scientific, technical or business information belonging to the
        disclosing Party, which the disclosing Party marks "Confidential" if
        disclosed in writing, or which the disclosing Party identifies as
        confidential at the time of any visual or oral disclosure and promptly
        confirms in writing to have been confidential. Except to the extent
        expressly authorized by this Agreement, the Parties agree that, for the
        Access Term and for five (5) years thereafter, the receiving Party shall
        keep confidential and shall not publish or otherwise disclose and shall
        not use for any purpose (except those expressly permitted under this
        Agreement) any Confidential Information furnished to it by the other
        Party pursuant to this Agreement, and regardless of the medium on which
        it is provided, including know-how, except to the extent that it can be
        established by the receiving Party by competent proof that such
        information:

               (a) was already known to the receiving Party, other than under
               an obligation of confidentiality, at the time of disclosure by
               the other Party;

                                       13

<PAGE>   15
          (b) was generally known to the public or otherwise part of the public
          domain at the time of its disclosure to the receiving Party;

          (c) became generally available to the public or otherwise part of the
          public domain after its disclosure other than through any act or
          omission of the receiving Party in breach of this Agreement;

          (d) was subsequently lawfully disclosed to the receiving Party by a
          third party having no confidentiality obligations to the disclosing
          Party with respect thereto;

          (e) was independently discovered or developed by the receiving Party
          without the use of the other Party's Confidential Information, and
          such independent discovery or development can be documented by the
          receiving Party's tangible records created at the time of such
          independent development.

6.2  Circumstances for Limited Disclosure. Each Party may disclose the other's
     information to the extent such disclosure is reasonably necessary in (i)
     filing, prosecuting patent applications and maintaining patents, or (ii)
     prosecuting or defending litigation or (iii) complying with applicable
     governmental regulations, including laws and regulations governing the
     testing, approval, manufacture and marketing of foods, drugs, biologicals
     and medical devices; provided, however, that if a Party is required to
     make any disclosure of the other Party's secret or confidential
     information it will give reasonable advance Notice to the other Party of
     such disclosure requirement and will use its reasonable efforts to secure
     confidential treatment of such information required to be disclosed.

6.3  Other Disclosures. Notwithstanding anything to the contrary set forth
     herein, this Article 6.0 (Confidentiality) shall not be construed to allow
     CUSTOMER, CUSTOMER Affiliates, sublicensees, collaborators or consultants
     to publish or disclose the LifeArray(TM) Product(s), including
     Modifications, or substantial portions thereof, or any Incyte software or
     hardware configurations, at any time without the express written consent
     of Incyte.

            of such LifeArray(TM) Products(s), including Modifications.
            Thereafter, CUSTOMER shall have no right to the LifeArray(TM)
            Products(s) or Modifications, including any right to use, copy,
            modify, adapt, create derivative works with respect to same.

7.3   Breach.

            (a)   Failure by either Party to comply with any of the material
            obligations contained in this Agreement shall entitle the other
            Party to give to the Party in default written notice specifying the
            nature of the default and requiring it to make good such default.
            If such default is not cured within ninety (90) days after the
            receipt of such written notice, the notifying Party shall be
            entitled, without prejudice to any of its other rights conferred on
            it by this Agreement and in addition to any other remedies
            available to it by law or in equity, to immediately terminate this
            Agreement by giving written notice to the other Party. The right of
            a Party to terminate this Agreement, as hereinafter provided, shall
            not be affected in any way by its waiver or failure to take action
            with respect to any previous default.

            (b)   Upon the happening of any of the following events there shall
            be deemed to be a breach of the terms of this Agreement and the
            non-breaching Party, at its option, shall have the right to cease
            performance hereunder until such breach is remedied, or to
            terminate this Agreement as provided for above in this Section 7.4
            (Breach):

            (i)   a Party fails to make any payment when due as required by
                  this Agreement; provided, however, that the first occurrence
                  of late payment shall not constitute breach unless not cured
                  within thirty (30) days of notice of such failure by the
                  other Party;



                                       15
<PAGE>   17
          (ii)  the other Party violates or fails to perform any of the other

                following its receipt from the other Party of written notice
                specifying such material violation or material failure and
                demanding that it be cured; or

          (iii) the other Party ceases doing business as a going concern; makes
                an assignment for the benefit of creditors; admits in writing

                the subject of any other voluntary or involuntary bankruptcy or
                insolvency proceedings.

     this Agreement:

          (a) Incyte will be entitled to payment, under the payment terms of
          Article 5.0 (Schedule of Payments), for all authorized services
          rendered to CUSTOMER under Article 2.0 (Installation; Systems
          Integration) that are performed in accordance with the specifications
          therefor prior to the effective date of termination; and

          (b) CUSTOMER will be entitled to a return of any payments made in
          excess of work actually performed by Incyte under Article 2.0
          (Installation;  Systems Integration) in accordance with the

          for in Section 7.2 (Expiration of the Access Term).

7.5  Dispute Resolution Procedures. If the parties cannot resolve a dispute

          insolvent or bankrupt, or ii) shall have made an assignment for the

          effect.

          (b) Promptly following the Acceptance Date, Incyte shall deposit with

          correct copy of the source code for the LifeArray(TM) Product(s)
          provided to CUSTOMER hereunder (the "Escrowed Source Code"), and
          shall enter into an escrow agreement with CUSTOMER and the Escrow
          Agent (the "Escrow Agreement"). The Escrow Agreement shall provide
          that the Escrowed Source Code shall be delivered to CUSTOMER only

          the filing thereof; iii) failure of Incyte to provided maintenance
          and support services hereunder; or iv) the liquidation or dissolution
          of Incyte. From time to time after the initial escrow deposit, if
          Incyte makes any material modifications, updates or enhancements to
          any of the Escrowed Source Code, Incyte shall deposit with the Escrow
          Agent a copy of such modified, updated or enhanced source code.

          to the Incyte Technology as of the Effective Date of this Agreement
          that would materially interfere with Incyte's performance of its
          obligations under this Agreement. Furthermore, Incyte shall disclose
          to CUSTOMER any material adverse proceedings, claims or action that
          arise and come to the knowledge of Incyte (without undertaking a
          special investigation) relating to Incyte Technology during the

     the generality of the foregoing, each Party shall be responsible for

     patent rights, copyrights or other intellectual property rights.
     Notwithstanding the foregoing, it shall be CUSTOMER's sole responsibility

<PAGE>   22
          misrepresentation contained herein by Incyte, or (5) infringement by
          Incyte of any third party's patent rights, copyrights or other
          intellectual property rights.

     9.3  Claims. If any claim is made against either Party under Sections
          9.1(i) (Incyte) or 9.2(i) (CUSTOMER), above for which indemnification
          is available hereunder, the indemnifying Party, at its option, shall:

               (a)  defend the other Party against such claim;

               (b)  acquire for the other Party the right to continue using any
               Software or product licensed hereunder that is the subject of
               such claim;

               (c)  replace any Software or product licensed hereunder with
               other Software or product for which there exists no infringement
               claim, which serves materially the same purpose and function as
               the claimed infringing Software or product; or

               (d)  modify the Software or product to make it non-infringing;
               provided, however, that no Party shall have any liability or
               obligation to the other under this Section 9.3 if any such
               infringement claim is based upon or arises out of:

                    (i)   any modification by the indemnified Party of any
                    portion of any Software or data not authorized by the
                    indemnifying Party in writing unless without such
                    modifications the Software would not be infringing;

                    (ii)  the use of any Software or product in violation of the
                    license granted in this Agreement; or

                    (iii) a patent, copyright or other intellectual property
                    right claim in which the indemnified Party or any affiliate
                    thereof has any direct or indirect interest by license or
                    otherwise; or

                    (iv)  use of old Software after receipt or replacement of
                    modified Software under 9.3(c) or (d) above.

     If the indemnifying Party elects 9.3(a) above, the indemnifying Party, at
     its expense, shall have the right to control the defense and settlement of
     any such claim and the indemnified Party shall reasonably cooperate with
     the indemnifying Party in such defense and settlement. If the indemnifying
     Party elects 9.3(c) above, the indemnified Party shall return to the
     indemnifying Party the claimed infringing Software or product, along with
     any copies, duplicates and other manifestations thereof in whatever form.

      This Section 9.3 states a Party's entire liability and obligation, and
      the other Party's exclusive remedy for infringement with respect to the
      first Party's software.

                         10.0 MISCELLANEOUS PROVISIONS.

10.1  Force Majeure. Force Majeure shall mean an Act of God, flood, fire,
      explosion, earthquake, strike, lockout, casualty or accident, war, civil
      commotion, act of public enemies, blockage or embargo, or any injunction,
      law, order, proclamation, regulation, ordinance, demand or requirement of
      any government or any subdivision, authority representative thereof, or
      the inability to procure or use materials, labor, equipment,
      transportation or energy sufficient to meet manufacturing needs without
      the necessity of allocation, or any other cause whatsoever, whether
      similar or dissimilar to those enumerated above, which are beyond the
      reasonable control of such Party, which the Party affected has used its
      reasonable best efforts to avoid, and which prevent, restrict or
      interfere with the performance by a Party of its obligations hereunder.
      The Party affected by Force Majeure shall give notice to the other Party
      promptly in writing and whereupon shall be excused from those obligations
      hereunder, to the extent of such prevention, restriction or interference,
      provided that the affected Party shall use its commercially reasonable
      efforts to avoid or remove such cause(s) of non-performance and shall
      continue performance whenever such cause(s) is removed.

10.2  Governing Law. This Agreement shall be governed by and construed in
      accordance with the laws of the State of Delaware, without regard to any
      such laws relating to choice or conflict of laws.

      this Agreement shall be valid or effective unless made in writing and
      signed by a duly authorized officer of each of the parties.

10.4  Headings. The headings and captions used in this Agreement are intended
      for convenience only and shall have no force or effect whatsoever in the

      hereunder except: (i) as incident to the merger, consolidation,
      reorganization or acquisition of stock or assets or similar transaction
      affecting all or substantially all of the assets or voting control of the
      assigning Party; (ii) to any directly or indirectly wholly-owned
      affiliate if the assigning Party remains liable and responsible for the
      performance and observance of all of the subsidiary's duties and
      obligations hereunder; (iii) with respect


                                       22

      to either Party as the assignor, as incident to the acquisition or
      transfer of the assets affecting all or substantially all of the assets

      that the acquiring entity or transferee continues to fulfill its
      obligations to the other Party hereunder; or (iv) with the consent of the
      other Party, which consent shall not be withheld unreasonably. This
      Agreement shall be binding, upon the successors and permitted assigns of
      the parties and the name of a Party appearing herein shall be deemed to
      include the names of such Party's successor's and permitted assigns to
      the extent necessary to carry out the intent of this Agreement. Any
      assignment not in accordance with the above shall be void. Any assignment
      by CUSTOMER hereunder shall be subject to CUSTOMER's obligations under
      Section 5.4 (Payments and Taxes).

10.6  Counterparts.  This Agreement may be executed in two or more
      counterparts, each of which shall be deemed an original for all purposes.

10.7  Severability.  If any term, clause or provision of this Agreement shall
      be judged invalid for any reason whatsoever by a court of competent
      jurisdiction, such invalidity shall not affect the validity or operation

      provision shall be deemed to have been deleted from this Agreement.

10.8  Notices.  Any notice, requests, delivery, approval or consent required or
      permitted to be given under this Agreement shall be in writing and shall

10.9  Waiver.  The failure of either Party to enforce at any time any of the
      provisions of this Agreement, or the failure to require at any time
      performance by the other Party of any of the provisions of this
      Agreement, shall in no way be construed to be a present or future waiver
      of such provisions, nor in any way affect the validity of either Party to
      enforce each and every such provision thereafter. The express waiver by
      either Party

                                       23
<PAGE>   25
      of any provision of this Agreement shall not constitute a waiver of any
      future obligation to comply with such provision.

10.10 Remedies. All rights and remedies conferred upon either Party under this
      Agreement or by any other instrument or law shall be cumulative and may be
      exercised singularly or cumulatively.

10.11 Binding Effect. This Agreement shall be binding upon and inure to the
      benefit of parties and their respective successors and permitted assigns.

10.12 Injunctive Relief. The parties acknowledge that because of the
      confidential and proprietary nature of the Confidential Information,
      neither termination of this Agreement nor an action at law would be an
      adequate remedy for a material breach by either Party of its obligations
      under Article 6.0 (Confidentiality). Accordingly, each Party agrees and
      consents that in the event of such breach, in addition to all other
      remedies which the other Party may have, such other Party shall be
      entitled to seek appropriate equitable relief in addition to whatever
      remedies it might have at law, including injunctive relief, specific
      performance or such other relief as such Party may request to enjoin or
      otherwise restrain any act prohibited hereby without the necessity of
      proof of actual damages, as well as the recovery of all costs and
      expenses, including attorney's fees incurred. Nothing in this Agreement
      shall be construed to prevent or restrict a Party from seeking relief in a
      court of competent jurisdiction to protect, enforce or defend any patent
      rights, copyrights, names, marks, or other proprietary or confidential
      information owned or possessed by, or licensed by or to, a Party.

10.13 Exhibits. Each reference in this Agreement to an Exhibit shall mean a
      Exhibit attached to this Agreement and incorporated into this Agreement by
      such reference.

10.14 No Employment Relationship or Partnership. The parties shall at all times
      be independent contractors and nothing in this Agreement shall be deemed
      to create a partnership or joint venture between the parties. Neither any
      Party nor any of its employees shall have any ability to legally bind the
      other Party with respect to any third party or to incur any obligation or
      liability on behalf of the other Party.

10.15 Public Announcements. Except as may otherwise be required by law or
      regulation, neither Party shall make any public announcement concerning
      this Agreement or the subject matter hereof without first submitting a
      copy of the proposed announcement to the other Party for review. The other
      Party shall have seven (7) business days to consent to the publication of
      such announcement, such consent not to be unreasonably withheld.

10.16 Further Actions. Each Party agrees to execute, acknowledge and deliver
      such further instruments, and to do all such other acts, as may be
      necessary or appropriate in order to carry out the purposes and intent of
      this Agreement.


                                       24

10.17  No Trademark Rights. Except as otherwise provided herein, no right,
       express or implied, is granted by this Agreement to use in any manner the
       names "diaDexus" or "Incyte", or any other trade name or trademark of
       CUSTOMER or Incyte, including, without limitation, "LifeArray(TM)" or
       "LifeSeq(R)", in connection with the performance of this Agreement.

10.18  Attorney's Fees. In any litigation relating to or arising out of this
       Agreement, the prevailing Party shall be entitled to reasonable
       attorneys' fees, including expert witness costs, and all costs of
       proceedings incurred in such litigation, in addition to any other relief
       that may be awarded.

10.19  Affiliate Performance. To the extent that any CUSTOMER affiliate has
       access to any LifeArray(TM) Product(s), has the right to receive any
       other rights or benefits under this Agreement or otherwise is obligated
       to perform any obligations under this Agreement, CUSTOMER shall cause
       such CUSTOMER Affiliate to perform in full, when due, all applicable
       obligations under this Agreement to the same extent as if such affiliate
       were a party to this Agreement; provided, however, that nothing in this
       Section 10.19 shall expand the rights or benefits of CUSTOMER or CUSTOMER
       Affiliates, or the obligations of Incyte, beyond those otherwise
       expressly set forth in this Agreement. CUSTOMER shall guaranty timely
       performance in full by such CUSTOMER Affiliate of all such obligations. A
       breach by such CUSTOMER Affiliate of any such obligation shall constitute
       a breach by CUSTOMER of this Agreement and shall entitle Incyte to
       exercise its rights under Article 7.0 (Term and Termination) above, in
       addition to any other rights and remedies to which Incyte may be
       entitled.

IN WITNESS WHEREOF, the Parties have caused this Agreement to be executed on
their behalves by their respective duly authorized representatives as of the
Effective Date.
