     license shall be exclusive even as to SuperGen, except to the extent
     necessary to enable SuperGen to perform any obligations or activities
     that SuperGen is required or permitted to perform under this Agreement.

     (c) Solely for the purpose of enabling Abbott to exercise its rights
     pursuant to Article 8.5 of this Agreement, SuperGen hereby grants
     Abbott a non-exclusive license to make and have made the Product in the
     Territories.

     (d) If at any time during the term of this Agreement, the financial
     resources of SuperGen are not reasonably sufficient to enable it to
     continue to meet its obligations hereunder for at least the next six
     months, SuperGen will so notify

                                                                            10

     Abbott and the parties will meet to review and consider steps that
     might be taken to preserve Abbott's rights to the SuperGen Technology
     under the terms of the Agreement.

2.6  RIGHTS TO ADDITIONAL PRODUCTS.

     (a) SuperGen hereby grants to Abbott, and Abbott hereby accepts, a
     right of first discussion with respect to all pharmaceutical compounds,
     other than the Compound, which are licensed to, owned by and/ or
     developed by SuperGen (regardless of their stage of development) as
     provided herein. If SuperGen desires to sell, or grant any rights
     relating to, any such compound, SuperGen shall first notify Abbott in
     writing, and shall provide to Abbott a data package which shall consist
     of all material information relating to such compound in the possession
     or control of SuperGen at such time, and shall also provide any other
     information in its possession or control reasonably requested by Abbott
     for the evaluation of the compound and the business opportunity. Within
     ninety (90) days after the receipt of the data package and such other
     information, Abbott shall notify SuperGen whether it is interested in
     such compound.

     (b) If Abbott notifies SuperGen that it is not interested in such
     compound, SuperGen shall be free to grant the rights declined by Abbott
     to any Third Party without restriction, or may commercialize directly.

     (c) If Abbott notifies SuperGen of Abbott's interest, the Parties
     shall, in good faith, negotiate the terms of an agreement under which
     SuperGen shall grant such rights to Abbott. If the Parties are unable
     to agree to the terms of such an agreement, after good faith
     negotiations, within ninety (90) days from SuperGen's receipt of such
     notice pursuant to this Article 2.6(c), then SuperGen shall be free to
     grant such rights to any Third Party, provided that SuperGen shall not
     enter into an agreement which grants any rights to such compound to any
     Third Party on terms which, taken as a whole, are more favorable to
     such Third Party than those offered to Abbott, without first offering
     such terms to Abbott. If SuperGen offers such terms to Abbott, then
     Abbott shall have thirty (30) days in which to notify SuperGen as to
     whether Abbott accepts such terms. If Abbott accepts such terms, then
     the Parties shall promptly enter into such agreement, granting such
     rights to Abbott.

     (d) In licensing any compounds from Third Parties, SuperGen shall use
     its reasonable efforts to ensure that such compound can be offered to
     Abbott in accordance with the provisions of this Section 2.6.

2.7  RIGHT OF FIRST REFUSAL FOR SUPERGEN ACQUISITION.

     (a) In the event that SuperGen wishes to initiate an inquiry or solicit
     an offer, or receives an offer or inquiry, from any Third Party
     relating to the potential merger with or acquisition of SuperGen or of
     a controlling portion of the voting

                                                                            11

                                              CONFIDENTIAL TREATMENT REQUESTED


     securities or substantially all of assets of SuperGen, SuperGen shall
     first so notify Abbott ("Acquisition Offer Notice") and Abbott shall have
     the right of first refusal to merge with or acquire SuperGen or a
     controlling portion of the voting securities or substantially all of
     assets of SuperGen.

     (b) The Acquisition Offer Notice shall set forth the principal
     financial and other terms under consideration by SuperGen. Abbott shall
     have ninety (90) days from receipt of the Acquisition Offer Notice to
     respond with either an offer to merger with or acquire SuperGen, or a
     notice that Abbott is not interested in making any offer to merge with
     or acquire SuperGen. If Abbott makes an offer to merge with or acquire
     SuperGen, the Parties shall enter into good faith negotiations for such
     merger or acquisition, and shall enter into a definitive agreement or
     agreements in order to effect such merger or acquisition subject to the
     terms and conditions of such definitive agreement or agreements. If the
     Parties are unable to reach agreement and to enter into such definitive
     agreement or agreements within ninety (90) days of the start of
     negotiations, then SuperGen shall be free to initiate an inquiry or
     solicit an offer, or to entertain an offer or inquiry, from any Third
     Party relating to the potential merger with or acquisition of SuperGen
     or of a controlling portion of the voting securities or substantially
     all of assets of SuperGen; provided that SuperGen shall not enter into
     any definitive agreement or agreements with any such Third Party, on
     terms and conditions equivalent to or more favorable to such Third
     Party than the terms and conditions last offered to Abbott by SuperGen,
     without first offering to enter into the definitive agreement or
     agreements with Abbott.

     (c) Notwithstanding any other provision of this Section 2.7, if the
     SuperGen Board of Directors determines in good faith that accepting an
     offer from Abbott to acquire SuperGen pursuant to this Section 2.7(a)
     or (b) would not meet the Board's fiduciary duties under applicable
     laws and regulations, then SuperGen's non-compliance with this Section
     2.7(a) or (b) shall not constitute a breach of this Agreement.

ARTICLE 3:  CLINICAL DEVELOPMENT, PRODUCT APPROVAL AND LAUNCH

3.1  CLINICAL DEVELOPMENT

     (a) SuperGen shall exercise its reasonable efforts to pursue, and shall
     bear the full cost and expense of, the Clinical Development of the

     shall act in accordance with Article 4.4 below, and in so doing SuperGen
     shall keep Abbott fully apprised with respect to its clinical development
     activities and shall provide Abbott with reasonable advance opportunity
     for input regarding these activities, including the right to review and
     approve the protocols and SuperGen's audit reports relating to all
     clinical studies.

     (b) Abbott shall exercise its reasonable efforts to pursue, and shall
     bear the full cost and expense of the clinical development of the
     Product for the countries of the International Territory other than
     Canada and the EU. Abbott shall keep SuperGen fully apprised with
     respect to its clinical development activities and shall provide
     SuperGen with reasonable advance opportunity for input regarding these
     activities, including the right to review the protocols and Abbott
     audit reports relating to all clinical studies.

3.2  U.S. REGULATORY APPROVAL. SuperGen shall exercise its reasonable efforts to
file, obtain and maintain Regulatory Approval for the Product in the United
States, and to obtain reimbursement approval for the Product in the United
States (including but not limited to any and all applicable programs
administered by government and private third-Party payors), and shall bear the
full cost and expense thereof. SuperGen shall keep Abbott fully apprised with
respect to its regulatory and reimbursement activity in the United States.
Specifically, SuperGen shall (i) promptly provide Abbott with a copy of all

3.3  INTERNATIONAL REGULATORY APPROVAL.

     (a) SuperGen shall provide Abbott, at SuperGen's expense, with the
     dossier SuperGen uses for obtaining U.S. Regulatory Approval, along
     with any and all other data, information and materials reasonably
     requested by Abbott for obtaining Regulatory Approval from the EMEA for
     the Product. Abbott shall exercise its reasonable efforts to file,
     obtain and maintain Regulatory Approval for the Products in the
     International Territory, and shall bear the full cost and expense
     thereof, provided that if the EMEA requests or requires additional
     clinical data beyond that provided to Abbott by SuperGen, or Abbott in
     its reasonable commercial judgement deems such additional clinical data
     to be necessary for such Regulatory Approval, then SuperGen shall
     reimburse Abbott for Abbott's costs and expenses for such additional
     clinical studies. Abbott shall keep SuperGen fully apprised with
     respect to its regulatory activity in the International Territory.
     Specifically, Abbott shall (i) promptly provide SuperGen with a copy of
     all filings, documents, and material correspondence with the relevant
     governmental authorities (without an obligation to translate into
     English,

                                                                            13

                                              CONFIDENTIAL TREATMENT REQUESTED


     unless otherwise available), and (ii) provide SuperGen with advance notice
     of meetings with such authorities and consider, at Abbott's sole
     discretion, SuperGen's request to attend or participate in any such
     meeting or to obtain a written right of reference to Abbott's regulatory
     filings for the Product in the International Territory.

     (b) Abbott shall use its reasonable efforts to obtain Regulatory
     Approval in at least three (3) of the following countries within five
     (5) years of SuperGen's receipt of U.S. Regulatory Approval: Mexico,
     Canada, Japan, the United Kingdom, France, Italy, Germany, and Spain.
     If Abbott fails to obtain Regulatory Approval pursuant to this Section
     3.3(b) within such time frame, SuperGen shall have the right to take
     over Abbott's Regulatory Approval efforts in these countries. In such
     event, Abbott shall transfer to SuperGen all of the filing materials or
     information then in Abbott's possession or control necessary for
     SuperGen to file for the Regulatory Approval, or to continue the filing
     if Abbott has commenced the filing process, in these countries.

3.4  REASONABLE COOPERATION.

     (a) Each Party shall provide the other Party with all reasonable
     assistance requested by the other Party with respect to the foregoing
     clinical development and regulatory activities, including, but not
     limited to, promptly providing the other Party with any and all
     authorizations, approvals, certificates of free sale, and other
     information, documents, materials and assistance reasonably required by
     the other Party to file, obtain, and maintain Regulatory Approval for
     the Product. The Party providing such assistance shall be reimbursed by
     the other Party for its reasonable out-of-pocket costs and expenses.

     (b) If SuperGen so requests and Abbott so agrees, Abbott shall perform
     certain clinical research services for particular clinical studies to
     be conducted by SuperGen, subject to the terms and conditions of a
     separate agreement between the Parties including, but not limited to,
     the provision for an appropriate fee to be paid Abbott for its services
     thereunder.

     (c) SuperGen shall provide to Abbott, at SuperGen's expense, the
     dossier SuperGen uses for obtaining U.S. Regulatory Approval, along
     with any and all other data, information and materials reasonably
     requested by Abbott for obtaining Regulatory Approval from the EMEA for
     the Product.

     (d) In connection with its NDA for the Product in the U.S. Territory,
     and with Abbott's NDAs for the Product in the International Territory,
     SuperGen shall take any and all actions necessary or reasonably
     requested by Abbott in order to qualify Abbott as a secondary
     manufacturing source for the Product in the Territories, solely for the
     purpose of enabling Abbott to exercise its rights pursuant to Article
     8.5 below without delay or impediment in the supply of Product to
     Abbott for Sale in the Territories.

                                                                            14

                                              CONFIDENTIAL TREATMENT REQUESTED

         (e) Within four (4) months of the Effective Date, the respective
         pharmacovigilance groups of each Party shall prepare and enter into a
         separate agreement relating to the exchange of adverse event
         information.

3.5  EXCUSED PERFORMANCE. The Parties acknowledge and understand that the
development, obtaining of Regulatory Approval, and marketing of the Product, as
with any pharmaceutical product, is subject to certain inherent risks including
that (a) the Product will be ineffective, toxic, or will not receive Regulatory
Approval, or will receive Regulatory Approval but with labeling which the
Parties agree is insufficient to render the Product commercially viable; (b) the
Product will be too expensive to manufacture or market or will not achieve broad
market acceptance; (c) Third Parties will hold proprietary rights that will
preclude the marketing and sale of the Product; or (d) Third Parties will market
equivalent or superior products. Neither Party makes any representation or
warranty that the Product (i) will be successfully developed; (ii) will receive
all necessary and/ or commercially viable Regulatory Approvals, (iii) will be
Launched; or (iv) will be commercially successful. The respective obligations of
the Parties under this Article 3, and Articles 4 and 5 below, are expressly
conditioned upon the safety, efficacy and commercial feasibility of the Product,
and, except as expressly provided herein, a Party's obligation hereunder shall
be delayed or suspended for so long as any condition or event exists which
reasonably causes a Party to question the safety, efficacy or commercial
feasibility of the Product. Furthermore, Abbott's obligation to market and
Promote the Product in a given country in the International Territory shall not
apply if Abbott has not commenced or has ceased marketing the Product in such
country substantially due to adverse business or financial conditions, including
those caused by the regulatory authorities or other governmental authorities of
such country, which would cause the marketing of such Product in such country to
be contrary to the financial best interest of the Parties. Each Party shall
promptly notify the other Party in the event any material issue arises as to the
safety, efficacy, commercial feasibility, or adverse business or financial
conditions with respect to any Product.

3.6  ABBOTT SUPPORT OF DEVELOPMENT EFFORTS. Abbott shall staff incremental
headcount in support of the clinical, regulatory and CMC obligations set forth
in this Agreement. SuperGen shall make the following payments to Abbott in cash
to cover Abbott's expenses for such support: a total of three million dollars
($3,000,000), with a first installment of seven hundred fifty thousand dollars
($750,000) payable on April 1, 2000, followed by seven (7) equal installments of
three hundred seventy-five thousand dollars ($375,000) per installment payable
within five (5) days of the beginning of each calendar quarter thereafter,
through calendar year 2001.

3.7  SUPERGEN DEVELOPMENT EFFORTS. SuperGen shall ensure that the development
activities it undertakes pursuant to Article 3 and Article 4 hereof shall be
carried out in accordance with Current Good Clinical Practice, Current Good
Laboratory Practice and Current Good Manufacturing Practice.

3.8  GOOD CLINICAL PRACTICE AUDITS. The parties shall appoint a mutually
acceptable

                                                                            15

                                              CONFIDENTIAL TREATMENT REQUESTED


third party independent clinical research organization to conduct a Current
Good Clinical Practice audit of the clinical development activities set forth
herein in each of June 2000 and December 2000 (each, a "GCP Audit"). The
costs of both GCP Audits shall be borne by SuperGen. If either GCP Audit
reveals a material deficiency which Abbott concludes, in its sole discretion,
may jeopardize the success of the U.S. NDA filing for the Product, and if
SuperGen does not rectify such deficiency to Abbott's reasonable satisfaction
within sixty (60) days of Abbott's notice of such deficiency, then Abbott
shall thereafter assume all development and registration activities for the
Product in the Territories, including but not limited to conducting or having
conducted, and completing or having completed, all clinical studies and other
activities required for Regulatory Approvals under the Development Plan.
Abbott shall use reasonable efforts to pursue such development and
registration activities under the Development Plan with the objective of
filing applications for Regulatory Approval throughout the Territories. In
the event that Abbott assumes SuperGen's development and registration
responsibilities pursuant to this Section 3.8, (i) SuperGen shall remain
responsible for all costs and expenses otherwise payable by SuperGen under
Article 3 and Article 4 hereof; and (ii) SuperGen shall transfer to Abbott
all of the filing materials and information in SuperGen's possession or
control necessary for Abbott to develop the Product and file for Regulatory
Approvals.

3.9  ABBOTT OPTION. SuperGen shall have ninety (90) days from completion of the
Phase III pancreatic cancer clinical studies with the Product to determine
whether the results of such study are sufficient to support an NDA filing for
the Product in the United States. In the event that SuperGen determines that
such results are insufficient to support such a filing and SuperGen elects not
to continue any further development of the Product, Abbott shall have the option
to thereafter assume all development and registration activities for the Product
in the Territories, including but not limited to conducting or having conducted,
and completing or having completed, all clinical studies and other activities
required for Regulatory Approvals under the Development Plan. Abbott shall use
reasonable efforts to pursue such development and registration activities under
the Development Plan with the objective of filing applications for Regulatory
Approval throughout the Territories. In the event that Abbott exercises its
option under this Section 3.9, (i) Abbott shall further develop the Product at
Abbott's sole cost and expense and in Abbott's sole discretion as to the
development strategy and plan, and (ii) SuperGen shall transfer to Abbott all of
the filing materials and information in SuperGen's possession or control
necessary for Abbott to develop the Product and file for Regulatory Approvals.
In such event (i) for the U.S. Territory, the provisions for profit sharing
under Article 6 below shall not apply and instead the Parties shall negotiate in
good faith a royalty based on Abbott's Net Sales in the U.S. Territory; and (ii)
the provisions of Article 7 below shall apply for the International Territory.

3.10 ABBOTT ACCESS TO DATA. Promptly after the Effective Date and throughout the
term of this Agreement, SuperGen shall provide to Abbott, within a reasonable
time, a shared database so that Abbott shall have ready access to all
preclinical and clinical and manufacturing documentation, information and data
resulting from SuperGen's Product research and development activities in the
Territories which Abbott requires for regulatory filings in the Territories or
which Abbott may reasonably request, including

                                                                            16

<PAGE>

                                              CONFIDENTIAL TREATMENT REQUESTED


but not limited to the studies set forth in Exhibit 3.1, case report forms,
monitoring documents, patient informed consents, institutional review board
approvals, medical and statistical programming and study reports for
individual studies, clinical data summaries, and expert reports. Upon
Abbott's request, SuperGen shall provide Abbott with copies of such
documentation and data. If at any time during this Agreement SuperGen fails
to provide Abbott with such database (including but not limited to any
updates thereof) or any such access in a reasonable timely fashion, and if
SuperGen does not provide such database and/ or access to Abbott within sixty
(60) days of Abbott's notice to SuperGen of such failure, then Abbott shall
have the option to thereafter assume all development and registration
activities for the Product in the Territories, including but not limited to
conducting or having conducted, and completing or having completed, all
clinical studies and other activities required for Regulatory Approvals under
the Development Plan. Abbott shall use reasonable efforts to pursue such
development and registration activities under the Development Plan with the
objective of filing applications for Regulatory Approval throughout the
Territories. In the event that Abbott exercises its option under this Section
3.10, (i) Abbott shall develop the Product at SuperGen's sole cost and
expense and SuperGen shall transfer to Abbott all of the filing materials and
information in SuperGen's possession or control necessary for Abbott to
develop the Product and file for Regulatory Approvals.

ARTICLE 4:  CO-PROMOTION AND PROMOTION

4.1  MARKETING EFFORT. Abbott and SuperGen shall use their reasonable efforts to
Co-Promote the Product in the U.S. Territory, and Abbott shall use its
reasonable efforts to Promote the Product in the International Territory, to
maximize Product Sales in the Territories. Abbott shall use its reasonable
efforts to implement, and shall make tactical decisions with regard to,
Promotion in the International Territory, consistent with the terms of this
Agreement.

4.2  U.S. MARKETING BOARD.

     (a) Abbott and SuperGen shall work together to Co-Promote the Product
     in the U.S. Territory and shall present their views on the Co-Promotion
     of the Product through a committee (the "U.S. Marketing Board") which
     shall oversee and direct the Co-Promotion of the Product in the U.S.
     Territory. The U.S. Marketing Board shall review and approve strategies
     for the Co-Promotion of the Product, develop and approve the annual
     Co-Promotion budget, and undertake the activities necessary to
     implement those strategies in accordance with a U.S. Co-Promotion Plan
     and U.S. Promotional Materials (including by coordinating the Parties'
     Detailing messages and methodologies, physician, trade, managed care
     and formulary committee targeting, and call programs and efforts).

              (i) The U.S. Marketing Board shall consist of no more than
              four (4) individuals, two (2) of which shall be
              representatives, respectively, from Abbott and SuperGen, and
              shall be chaired alternatively on an annual

                                                                            17

<PAGE>

                                              CONFIDENTIAL TREATMENT REQUESTED


              basis by one (1) of the SuperGen representatives and by one
              (1) of the Abbott representatives. Each Party's representatives
              on the U.S. Marketing Board shall be full-time employees of such
              Party and each shall have one (1) vote on any matter arising for
              decision by the Board. The U.S. Marketing Board may invite,
              from time to time, one or more additional employees of the
              Parties who offer specialized assistance to the Board (e.g.,
              legal, finance or regulatory personnel) to participate in any
              meeting in a non-voting, advisory capacity, provided that,
              when one or more specialists from one Party is invited, the
              same number of similar specialists from the other Party shall
              also be invited to the same meeting. Each Party shall have the
              right, at any time, to designate by written notice to the
              other Party, a replacement, on a permanent or temporary basis,
              for any of such Party's members on the U.S. Marketing Board.

              (ii) The U.S. Marketing Board shall be responsible for making
              all final decisions related to the Co-Promotion of the Product
              in the U.S. Territory, pursuant to the terms and conditions of
              this Agreement. Each Party shall use its reasonable efforts to
              implement the final decisions of the U.S. Marketing Board.

              (iii) The U.S. Marketing Board shall endeavor to work by
              consensus. In the event of a deadlock in any vote or on any
              issue relating to this Section 4.2, the Parties shall refer
              the deadlocked issue to SuperGen's Executive Vice President of
              Commercial Operations and Abbott's Hospital Products Division
              Vice President of Commercial Operations. These individuals
              shall attempt, promptly and in good faith, to resolve such
              issue amicably. If such issue remains deadlocked, the Parties
              shall refer such issue to, respectively, the President of
              SuperGen, and the President of Abbott's Hospital Products
              Division. Any issue remaining deadlocked after this last step
              shall be resolved through an Alternative Dispute Resolution
              ("ADR") procedure pursuant to Section 20.3 below.

              (iv) During the first three (3) Sales Years in the U.S.
              Territory, the U.S. Marketing Board shall meet as necessary,
              in person or otherwise as the Parties shall agree, but no less
              than once per calendar quarter. Thereafter, for the remaining

     on an annual budget for the Co-Promotion of the Product in the U.S.
     Territory (the "U.S. Co-Promotion Budget"), which shall set forth in

          No later than February 1               No later than May 1
          No later than June 1                   No later than September 15.

     (c) No later than November 15th of each year during the term of this
     Agreement, the Parties shall reach written agreement, through the U.S.
     Marketing Board, on an annual plan for the Co-Promotion of the Product
     in the U.S. Territory (the "U.S. Co-Promotion Plan"). The U.S.
     Marketing Board shall oversee the implementation of the U.S.
     Co-Promotion Plan. The U.S. Co-Promotion Plan shall specify the number
     of the total Sales Representatives required (measured on a full time
     equivalent basis) and define the activities of such Sales
     Representatives which are included in such Party's SG&A account
     hereunder (the "Detailing Commitment"), the sampling program for the
     Product (including a maximum number of Sample Packs), the Discretionary
     Funds available to the Sales Representatives, any Marketing Studies for
     the Product, medical education programs and special marketing incentive
     programs; provided, however, that, unless expressly agreed otherwise by
     the Parties, the Abbott Sales Representatives and the SuperGen Sales
     Representatives shall be treated in a like and equal manner such that:
     (i) the sampling program (as well as the number of samples) per Sales
     Representative shall be substantially the same for both sales forces;
     (ii) the level of Discretionary Funds per Sales Representative shall be

                                                                            19

                                              CONFIDENTIAL TREATMENT REQUESTED


     substantially the same for both Parties; and (iii) the amount and type
     of U.S. Promotional Materials per Sales Representative shall be
     substantially the same for both sales forces.

     (d) Under the U.S. Co-Promotion Budget and the U.S. Co-Promotion Plan,
     Abbott shall maintain no less than sixty percent (60%) of the total
     number of Sales Representatives required to Co-Promote the Product, and
     SuperGen shall be permitted to maintain up to forty percent (40%) of
     such total number of Sales Representatives.

     (e) Abbott and SuperGen shall be authorized to account for such Sales
     Representatives, on a fully allocated cost of one hundred seventy-five
     thousand dollars ($175,000) per full-time equivalent basis, as part of
     the Abbott SG&A and SuperGen SG&A, respectively (for example, two Sales
     Representatives who are full-time employees and are assigned to
     dedicate 50% of their time to the Product shall be counted as one
     full-time equivalent at a cost of $175,000). The cost of one hundred
     seventy-five thousand dollars ($175,000) per full-time equivalent shall
     be increased no more than once per calendar year based upon the U.S.
     Consumer Price Index.

     (f) Each Party shall be responsible for staffing, selling skills
     training, supervising, and compensating (including incentives) its own
     Sales Representatives. The Parties shall jointly develop, review and
     agree upon Product-specific training materials, and shall use the same
     such training materials, for their respective Sales Representatives.
     The Parties shall conduct Product training for their respective Sales
     Representatives jointly, at such times and in such manner as set forth
     in the U.S. Co-Promotion Plan. Each Party shall have full control over
     and be responsible for the salary, incentives, benefits and other
     employment matters related to its Sales Representatives.

     (g) Each Party shall use its reasonable efforts to perform those tasks
     and responsibilities assigned to such Party in the U.S. Co-Promotion
     Plan. The Detailing of a Product shall commence upon the Launch of such
     Product. Each Party may perform Details throughout the U.S. Territory.
     The U.S. Marketing Board shall coordinate the Parties' Detailing
     activities so as to maximize Product sales by, for example, maximizing
     geographic coverage, eliminating unnecessary duplication, identifying
     promising managed care targets, enhancing managed care penetration, and
     optimizing participation in conventions continuing educational programs
     for health care professionals.

     (h) As part of the Co-Promotion of the Product in the U.S. Territory,
     each Party may distribute a reasonable number of Sample Packs free of
     charge to health care professionals on an ongoing basis in accordance
     with the sampling program as outlined in the U.S. Co-Promotion Plan and
     approved by the U.S. Marketing Board. Each Party shall comply with all
     applicable laws and regulations with respect to the distribution of
     Sample Packs in the U.S. Territory,

                                                                            20

         including but not limited to maintaining all records required pursuant
         to the Prescription Drug Marketing Act of 1987. Abbott shall promptly
         report to SuperGen any thefts of Sample Packs or any losses of Sample
         Packs. SuperGen shall be responsible for providing to both Parties'
         sales forces the quantities of Sample Packs set forth in the U.S. Co-
         Promotion Plan.

         (i) SuperGen and Abbott shall jointly develop, review and agree upon
         the U.S. Promotional Materials from a regulatory and medical
         perspective. To the extent that any U.S. Promotional Materials are
         required by law or regulation to be submitted to the FDA, SuperGen
         shall make such submissions; and SuperGen shall be the FDA liaison for
         both Parties on all marketing issues. The Parties shall disseminate in
         the U.S. Territory only those promotional and advertising materials
         which have been approved for use by the U.S. Marketing Board. Neither
         Party shall be required to use U.S. Promotional Materials which are
         prohibited under applicable FDA regulations or other applicable laws
         and regulations, or which have not been approved in writing by that
         Party's responsible regulatory and medical departments. Abbott and
         SuperGen shall use the same U.S. Promotional Materials in connection
         with the Co-Promotion of the Product.

         (j) Each Party shall cause its sales force, and all other employees and
         approved agents and representatives, to comply with all applicable laws
         and regulations in connection with the Co-Promotion of the Product in
         the U.S. Territory, including but not limited to applicable FDA
         regulations, the Prescription Drug Marketing Act and the Federal
         Anti-Kickback Statutes. Each Party shall cause its sales force (A) to
         Co-Promote the Product consistently with the U.S. Marketing Board's
         then approved U.S. Promotional Materials and U.S. Co-Promotion Plan,
         and (B) not to do anything knowingly or recklessly which will
         jeopardize the goodwill or reputation of the Product or the other
         Party. In addition, each Party shall exercise its reasonable efforts to
         conduct the Co-Promotion of the Product in adherence to the American
         Medical Association Gifts to Physicians From Industry Guidelines.

         (k) In addition to the Co-Promotion activities covered under this
         Agreement, the U.S. Marketing Board may establish and operate an
         indigent program for distribution of the Product and/or Sample Packs to
         needy individuals and/or the physicians and other providers serving
         such needy individuals, and an expanded access program. The costs and
         expenses of both the indigent program and the expanded access program
         shall be included as part of SuperGen SG&A and Abbott SG&A, as the case
         may be. SuperGen shall provide for reasonable telephone support
         services for reimbursement under this program during normal business
         hours.

         (l) Notwithstanding anything in this Agreement to the contrary, if at
         any time during the term of this Agreement SuperGen notifies Abbott of
         its decision not to Promote or to cease to Promote the Product in the
         U.S. Territory, then the U.S. Marketing Board shall cease to exist as
         of the date of such notice and Abbott shall


                                                                             21

         determine, in its sole discretion, the strategy, tactics, materials and
         budget for the Promotion of the Product in the U.S. Territory. In such
         event, however, SuperGen shall remain obligated to make the minimum
         four million dollar ($4,000,000) pre-marketing and marketing
         expenditure as provided in Article 4.2(b) above, to comply with the
         provisions of Article 4.2(j) above, and to provide telephone support
         services in connection with reimbursement under any indigent program
         and/ or expanded access program for the Product in accordance with
         Article 4.2(k) above.

4.3    INTERNATIONAL TERRITORY. Abbott shall use its reasonable efforts, to the
extent possible, to coordinate its promotional activities and methods in the
International Territory with those used by the Parties in the U.S. Territory.
Abbott shall cause its sales force, and all other employees and approved agents
and representatives, to comply with all applicable laws and regulations in
connection with the Promotion of the Product in the International Territory.

                  (iii) shall act in an advisory capacity to the Parties with
                        respect to (1) potential combination therapies using the
                        Product and one or more other pharmaceutical products;
                        and (2) studies to obtain additional approved

                        when and how to close the data base, when and how to
                        file for Regulatory Approval, when and how to conduct
                        interim analyses, and all protocols for clinical

                       Committee;

                  (ii)  final decisions with respect to Marketing Studies
                        intended for use solely within the U.S. Territory shall
                        be made by the U.S. Marketing Board, and by Abbott with
                        respect to Marketing Studies intended for use solely
                        within the International Territory, irrespective of the
                        country or countries in which such Marketing Studies are
                        conducted;

                  (iii) final decisions with respect to clinical development for
                        the Product in the International Territory outside the
                        EU, and for clinical development and regulatory strategy
                        for the Product in the International Territory, shall be
                        made by Abbott; and

                  (iv)  The Clinical Development Committee shall endeavor to
                        work by consensus. In the event of a deadlock in any
                        vote or on any issue relating to this Section 4.4 on
                        which the Clinical Development Committee is to make a
                        final decision, the Parties shall refer the deadlocked
                        issue to SuperGen's Executive Vice President of Medical
                        Affairs and Abbott's Hospital Products Division Vice
                        President of Medical Affairs. These individuals shall
                        attempt, promptly and in good faith, to resolve such
                        issue amicably. If such issue remains deadlocked, the
                        Parties shall refer such issue to, respectively, the
                        President of SuperGen, and the President of Abbott's
                        Hospital Products Division. Any issue remaining
                        deadlocked after this last step shall be resolved
                        through an Alternative Dispute Resolution ("ADR")
                        procedure pursuant to Section 20.3 below.

       (c) The cost of any clinical study for the Product in the U.S., the EU

          to Section 3.1 above undertaken by a Party or by the Parties shall be
          approved in advance by the Clinical Development Committee and shall
          be borne in equal shares by the Parties. The Parties shall use their
          reasonable efforts, working through the Clinical Development
          Committee, to coordinate Marketing Study strategies and the
          implementation of such strategies so as to maximize the benefit of
          Marketing Studies to the Product worldwide and to avoid duplication
          or conflict in such Marketing Studies.

       (d) At any time during the term of this Agreement, whether through the
           Clinical Development Committee or otherwise, if SuperGen develops or
           SuperGen and Abbott jointly develop any improvements, modifications,
           enhancements, additions to or extensions of the Product (an
           "Improvement"), such Improvement shall be deemed to be a Product
           under this Agreement. The Parties shall bear in equal shares the cost
           of developing such Improvement for Co-Promotion by SuperGen and
           Abbott in the U.S. Territory and for


                                                                              23

           Promotion by Abbott in the International Territory pursuant to a
           development plan and budget to be agreed between the Parties. For
           purposes of clarification, the Parties agree that no milestones shall
           be payable by Abbott to SuperGen with respect to any such
           Improvement, but that the provisions for profit sharing under Article
           6 below and for royalties under Article 7 below shall apply to such
           Improvement(s). Notwithstanding anything to the contrary in this
           Agreement, if both Parties agree in writing to do so, then Abbott may
           take over the development of any one or more Improvements, at
           Abbott's sole cost and expense and at Abbott's sole discretion as to
           the development strategy and plan. In such an event: (i) for the U.S.
           Territory, the provisions for profit sharing under Article 6 below
           shall not apply to such Improvement(s) and instead, the Parties shall
           negotiate in good faith a royalty based on Abbott's Net Sales in the
           U.S. Territory; and (ii) the provisions of Article 7 below shall
           apply to any such Improvement(s) for the International Territory.

       (e) The Clinical Development Committee shall in good faith agree upon
           and complete a development plan for the activities required to
           achieve Regulatory Approvals of the Product in the U.S., the EU and
           Canada (the "Development Plan") within ninety (90) days after the
           Effective Date.  The Development Plan shall include, but not be
           limited to, the activities set forth on Exhibit 4.4(e). It is the
           intent of the Parties that U.S. Phase III clinical data may be used
           together with European data, if needed, for the European regulatory
           filings and thus will be done to EMEA and U.S. standards and with
           EMEA and U.S. FDA acceptable endpoints.

4.5    NAMES. While the configuration and placement of the Abbott name and the
SuperGen name shall be decided by the U.S. Marketing Board in the U.S. Territory
and by Abbott for the International Territory, the Parties agree that Abbott's
name and SuperGen's name shall appear and be equally prominent on all Product,
Sample Packs and U.S. Promotional Materials in the U.S. Territory, to the extent
allowed by applicable laws and regulations. The Product's N.D.C. number shall be
in SuperGen's name. The Product will utilize an Abbott list number in the U.S.
Territory.

4.6    RESEARCH AND DEVELOPMENT BUDGET.

       (a) The Clinical Development Committee shall be responsible for
           reviewing and proposing timelines for research and development
           activities as well as an annual research and development budget
           ("Annual R&D Budget"). The Parties shall prepare general timelines
           and detailed budget estimates for all research and development
           activities as part of the Development Plan. In addition, the
           Development Plan shall also contain the agreed upon Annual R&D Budget
           for 2000.

       (b) For 2001 and every year of the Development Plan thereafter, the
           Clinical Development Committee shall prepare an Annual R&D Budget by
           June 1 of


                                                                              24

           the preceding year, which it shall submit to each Party for its final
           review and approval.

       (c) The Clinical Development Committee may propose adjustments to the
           Annual R&D Budget up to two (2) times per calendar year, for review

5.2  EQUITY PAYMENTS LIMITATION. The Parties acknowledge and agree that any and
     all milestone payments to be made by Abbott pursuant to this Agreement as
     equity investments in SuperGen shall be subject to the terms and conditions
     of the Stock Purchase Agreement, which terms and conditions shall govern in
     the event of any inconsistency or conflict between this Agreement and the
     Stock Purchase Agreement with respect to any equity investment in SuperGen
     by Abbott. In particular, the Parties acknowledge and agree that in no
     event shall Abbott be required to make any equity investment in SuperGen,
     through the payment of the equity milestones as set forth above or in any
     other manner, which would cause Abbott to own in excess of nineteen percent
     (19%) of the voting securities of SuperGen at any time; provided, however,
     that in the event that any equity investment to be made by Abbott under
     this


                                                                             28
<PAGE>

                                                CONFIDENTIAL TREATMENT REQUESTED

     Agreement would cause Abbott to own in excess of nineteen percent (19%)
     of the voting securities of SuperGen, then Abbott's obligation to make
     such equity investment shall be tolled for a period of one (1) year. If
     SuperGen increases its share capital (other than by purchase of any
     equity in SuperGen by Abbott) during such one-year period, such that
     Abbott would then be able to make such equity investment and would not
     thereby own in excess of nineteen percent (19%) of the voting securities
     of SuperGen, SuperGen may so notify Abbott and Abbott shall make such
     equity investment, provided that SuperGen may make only one such
     notification, with respect to the entire amount of such equity
     investment, during such one-year period. If by the end of such one-year
     period SuperGen has not increased its share capital (other than by
     purchase of any equity in SuperGen by Abbott) during such one-year
     period, such that Abbott would then be able to make such equity
     investment and would not thereby own in excess of nineteen percent (19%)
     of the voting securities of SuperGen, then Abbott shall have no further
     obligation to make such equity investment.

5.2      SINGLE PAYMENT OBLIGATION. Each of the foregoing milestones shall only
be paid once regardless of the number of acceptances or Launches with respect to
such Product, including multiple product forms of the same Compound, additional
active or inactive ingredients, indications, modalities and/or dosage strengths.

5.4      METHOD OF PAYMENT. All cash payments due under this Article 5 shall
be paid by wire transfer or by such other means agreed upon by the Parties,
in each case at the expense of Abbott, with twenty-four (24) hours advance
notice of each wire transfer, to the bank account(s) as SuperGen shall
designate in writing following the occurrence of each cash milestone event.

ARTICLE 6:        U.S. PROFIT SHARING

6.1      REPORTS BY ABBOTT. Within forty-five (45) days from the end of each
calendar quarter starting with the first calendar quarter for which the
Parties have budgeted expenditures under Article 4, Abbott shall deliver to
SuperGen a true and accurate written report showing whichever of the
following are applicable for such calendar quarter:

         (a) the Abbott Net Sales and Net Units of Product Sold in: (i) the U.S.
         Territory and (ii) the International Territory (each in the aggregate
         and on a country-by-country basis;

         (b) the Abbott Distribution Margin (including the Abbott Cost of Goods
         and the Abbott Distribution Expenses used to arrive at the Abbott
         Distribution Margin from the Abbott Net Sales) for the U.S. Territory;
         and

         (c) the Abbott Operating Margin (including the Abbott SG&A used to
         arrive at the Abbott Operating Margin from the Abbott Distribution
         Margin) for the U.S. Territory.


                                                                             29

                                                CONFIDENTIAL TREATMENT REQUESTED

6.2      REPORTS BY SUPERGEN. Within ten (10) days from the date of SuperGen's
receipt of Abbott's report pursuant to Article 6.1 above, SuperGen shall deliver
to Abbott a true and accurate written report showing whichever of the following
are applicable for such calendar quarter:

         (a) the SuperGen Product Sales in the U.S. Territory;

         (b) the SuperGen Distribution Margin for the U.S. Territory (including
         the SuperGen Cost of Goods used to arrive at the SuperGen Distribution
         Margin from the SuperGen Product Sales);

         (c) the SuperGen Operating Margin for the U.S. Territory (including the
         SuperGen SG&A used to arrive at the SuperGen Operating Margin from the
         SuperGen Distribution Margin in the U.S. Territory); and

         (d) the Abbott U.S. Profit Amount, the SuperGen U.S. Profit Amount, the
         U.S. Adjustment Amounts for each Party, and the Final Payment (as
         defined in Section 6.5 below) due to either Abbott or SuperGen.

6.3      U.S. PROFIT SPLIT. Commencing on the date of acceptance by the FDA
of the U.S. NDA for the Product, the U.S. Product Profit for each calendar
year (or portion thereof less than a full calendar year) shall be shared
equally between the Parties, fifty percent (50%) for SuperGen and fifty
percent (50%) for Abbott. The allocation of U.S. Product Profit (whether a
positive (profit) amount or a negative (loss) amount) between Abbott and
SuperGen pursuant to this Article 6.3 as of the end of the applicable
calendar quarter or year shall be called the "Abbott U.S. Profit Amount" and
the "SuperGen U.S. Profit Amount," respectively, which together shall equal
the U.S. Product Profit as of the end of such period. The Parties understand
that the U.S. Product Profit, the Abbott U.S. Profit Amount, and the SuperGen
U.S. Profit Amount can each be a negative number and represent a net loss.

6.4      U.S. ADJUSTMENT AMOUNT. With respect to the U.S. Territory, for each
calendar quarter of each calendar year, the "U.S. Adjustment Amount" shall be
determined for Abbott by subtracting the Abbott U.S. Profit Amount from the
Abbott Operating Margin in the U.S. Territory and shall be determined for
SuperGen by subtracting the SuperGen U.S. Profit Amount from the SuperGen
Operating Margin in the U.S. Territory. If the U.S. Adjustment Amount is
positive for one Party and negative for the other Party, then the Party with
the positive U.S. Adjustment Amount shall pay such amount to the other Party,
so that each Party receives or bears fifty percent (50%) of the U.S. Product
Profit for such calendar quarter.

6.5      FINAL PAYMENT. After each calendar quarter, any amount payable by
one Party to the other Party pursuant to Article 6.4. above ("Final Payment")
shall be paid by the owing Party within ten (10) business days of Abbott's
receipt of SuperGen's report under Section 6.2.

                                                                             30

6.6      YEAR-END RECONCILIATION. Within forty-five (45) days after the end
of each calendar year starting with the first calendar year for which the
Parties have budgeted expenditures under Article 4, the U.S. Product Profit
split between the Parties pursuant to Article 6.3 above for such calendar
year shall be recalculated (the "Reconciliation Amount") to reflect any
amended information (including, but not limited to, amended sales data,
product returns or chargebacks) relevant to the calculation of the
Reconciliation Amount for such calendar year. Within ten (10) business days
after any such recalculation, Abbott shall pay to SuperGen, or SuperGen shall
pay to Abbott, as the case may be, an amount equal to the difference between
the most recent prior calculation of the Final Payment or the Reconciliation
Amount and the latest Reconciliation Amount.

6.7      EXAMPLE OF U.S. PRODUCT PROFIT SHARING. Exhibit 6.7 attached hereto
shall illustrate, by way of example only and not as a limitation of any kind,
the method agreed by the Parties under this Article 6 for calculating and
splitting the U.S. Product Profit.

6.8      PAYMENT PROCEDURE. All payments due under this Article 6 shall be
paid in United States Dollars by wire transfer or by such other means agreed
upon by the Parties, in each case at the expense of the payor, for value no
later than the due date thereof (with twenty four (24) hours advance notice
of each wire transfer) to the bank accounts as the payee shall designate in
writing within a reasonable period of time prior to such due date.

6.9      RECORDS. Each Party shall keep and maintain records relating to the
subject matter of all reports and payments to be made pursuant to this
Article 6 for the U.S. Territory, so that the reports and payments may be
verified. Such records shall be open to inspection at any reasonable time
within two (2) years after the period to which such records relate, but in
any event not more than once per Sales Year, by a nationally recognized
independent certified public accountant selected by the inspecting Party,
approved by other Party, which approval shall not be unreasonably withheld,
and retained at inspecting Party's expense. Said accountant shall sign a
confidentiality agreement prepared by the other Party and shall then have the
right to examine the records kept pursuant to this Agreement and report to
the inspecting Party the findings (but not the underlying data) of said
examination of records as are necessary to evidence that the records were or
were not maintained and used in accordance with this Agreement. A copy of any
report provided to the inspecting Party by the accountant shall be given
concurrently to the other Party. If said examination of records reveals more
than five percent (5%) underpayment of the royalty payable, expenses for said
accountant shall be borne by other Party and the other Party shall promptly
pay to the inspecting Party the balance due plus interest calculated at the
prime rate of interest as reported in the WALL STREET JOURNAL for the date of
the accountant's report which reveals such underpayment.

6.10     TAXES. Where any sum due to be paid to a Party under this Article 6
is subject to any withholding or similar tax, the Parties shall use their
reasonable efforts to do all such acts and things and to sign all such
documents as will enable them to take advantage of any applicable double
taxation agreement or treaty. In the event there is no applicable double

treaty reduces but does not eliminate such withholding or similar tax, the
Party making a payment shall pay such withholding or similar tax to the
appropriate government authority, deduct the amount paid from the amount due
to the other Party, and secure and send to the other Party the best available
evidence of such payment.

6.11     NO DOUBLE COUNTING OF COSTS. For the purpose of determining any cost
or expense which is shared by the Parties under this Agreement or otherwise
invoiced by one Party to another under this Agreement, any cost or expense
allocated by either Party to a particular cost category shall be consistent
with the terms of this Agreement and shall not also be allocated to another

ARTICLE 7:  INTERNATIONAL ROYALTY

7.1      ROYALTY PERIOD AND ROYALTY RATE. For a period of ten (10) years from
the First Commercial Sale or so long as the Product remains Patent Protected
in any country in the International Territory, whichever is longer, ("Royalty
Period"), Abbott shall pay to SuperGen a royalty of * of the Abbott Net Sales
of the Product in the International Territory.

7.2      ROYALTY RATE REDUCTION If during the Royalty Period, a generic
version of the Product is marketed by a Third Party in a country in the
International Territory, the Parties shall promptly and in good faith
negotiate a reduction in the royalty rate for that country. If SuperGen and
Abbott do not agree on a reduction in the royalty rate under this
circumstance, then the appropriate reduction shall be determined in an ADR
pursuant to Article 20.3 herein. Once the appropriate royalty rate reduction
has been determined, the difference between the royalty amount paid by Abbott
from the date of initiation of ADR through the date of the ADR decision, and
the royalty amount due for such period under the reduced calculation shall be
credited against any future payments owed by Abbott to SuperGen.

7.3      ROYALTY STATEMENTS. Each royalty payment shall be accompanied by a
statement from Abbott showing Abbott Net Sales for the Product in the
International Territory, by country. The royalty shall be computed in United
States Dollars pursuant to Abbott's standard internal accounting practices
and policies.

7.4      ROYALTY PAYMENT. Royalty payments shall be made by Abbott to SuperGen
in United States Dollars within sixty (60) days after the last day of
February, May, August, and November for royalties accruing on Net Sales
during the three (3) preceding Months.

7.5      PAYMENT PROCEDURE. All payments due under this Article 7 shall be paid
by wire transfer or by such other means agreed upon by the Parties, in each
case at the expense of the payor, for value no later than the due date
thereof (with twenty four (24) hours

                                                                              32

advance notice of each wire transfer) to the bank accounts as the payee shall
designate in writing within a reasonable period of time prior to such due
date.

7.6      NO MULTIPLE ROYALTIES. No multiple royalties shall be payable because a
Product, its manufacture, use or sale is or shall be covered by more than one
Valid Claim of a patent included in the Licensed Patents or more than one patent
under the Licensed Patents.

7.7      SALES TO AFFILIATES. No royalties shall be payable on sales between and
among Abbott and/or its Affiliates, but shall be payable on the first sale by
Abbott and/or its Affiliates to a Third Party in the International Territory.

7.8      RECORDS. Abbott and/or its Affiliates shall keep and maintain records
of sales made pursuant to the license granted by SuperGen to Abbott for the
Product in the International Territory under this Agreement, so that the
royalty payable and the royalty statement may be verified. Such records shall
be open to inspection at any reasonable time within two (2) years after the
royalty period to which such records relate, but in any event not more than
once per Sales Year, by a nationally recognized independent certified public
accountant selected by SuperGen, approved by Abbott, which approval shall not
be unreasonably withheld, and retained at SuperGen's expense. Said accountant
shall sign a confidentiality agreement prepared by Abbott and shall then have
the right to examine the records kept pursuant to this Agreement and report
to SuperGen the findings (but not the underlying data) of said examination of
records as are necessary to evidence that the records were or were not
maintained and used in accordance with this Agreement. A copy of any report
provided to SuperGen by the accountant shall be given concurrently to Abbott.
If said examination of records reveals more than five percent (5%)
underpayment of the royalty payable, expenses for said accountant shall be
borne by Abbott and Abbott shall promptly pay to SuperGen the balance due
plus interest calculated at the prime rate of interest as reported in the
WALL STREET JOURNAL for the date of the accountant's report which reveals
such underpayment.

7.9      TAXES. Where any sum due to be paid to SuperGen under this Article 7 is
subject to any withholding or similar tax, the Parties shall use their
reasonable efforts to do all such acts and things and to sign all such documents
as will enable them to take advantage of any applicable double taxation
agreement or treaty. In the event there is no applicable double taxation
agreement or treaty, or if an applicable double taxation agreement or treaty
reduces but does not eliminate such withholding or similar tax, Abbott shall pay
such withholding or similar tax to the appropriate government authority, deduct
the amount paid from the amount due SuperGen and secure and send to SuperGen the
best available evidence of such payment.

8.1      PRODUCT DISTRIBUTION.

                                                                              33

         (b) Abbott shall use its reasonable efforts to distribute the Product
         in the Territories to maximize the sales of the Product in the

         the U.S. Territory for the Abbott Hospital Products Division fiscal
         quarter in which Abbott is purchasing such Product from SuperGen or

         the Abbott International Division fiscal quarter in which Abbott is
         purchasing such Product from SuperGen or from its designated Third
         Party manufacturer(s). Abbott shall calculate its average net selling
         price for this purpose in accordance with Abbott internal accounting
         policies and practices.

         (d) The Parties shall cooperate to determine manufacturing strategy and

         Product in the U.S. Territory, the U.S. Marketing Board shall establish
         a sales forecast for such Product specifying the Parties' anticipated
         requirements of the Finished Product in the U.S. Territory for the
         twelve (12) month period commencing approximately ninety (90) days
         prior to the anticipated date of Launch (the "U.S. Sales Forecast").
         The U.S. Marketing Board shall be responsible for establishing,
         preparing and updating the U.S. Sales Forecast.

         (f) Within twelve (12) months prior to the agreed projected Launch of
         the Product in the International Territory, Abbott shall establish a
         sales forecast for such Product specifying Abbott's anticipated
         requirements of the Finished Product in the International Territory for
         the twelve (12) month period commencing approximately ninety (90) days
         prior to the anticipated date of Launch (the "International Sales
         Forecast"). Abbott shall be responsible for establishing, preparing and
         updating the International Sales Forecast.

         (g) Such Sales Forecasts for the U.S. Territory and the International

         at the beginning of each calendar quarter, SuperGen shall have been
         provided with rolling Sales Forecasts for the twelve (12) month period
         commencing with the third (3rd) calendar quarter after the date on

         Agreement and none of the terms or conditions of Abbott's purchase
         orders, SuperGen's acknowledgment forms or any other forms exchanged by
         the parties shall be applicable, except those, to the extent consistent
         with the terms set forth herein, specifying quantity ordered,

                                                                              35

         Forecast covering such month (excluding any amendments subsequent to
         the original date of such Sales Forecast) shall be deemed accepted by
         SuperGen. SuperGen shall use its reasonable efforts to supply Abbott
         with any Finished Product in excess of one hundred twenty five percent
         (125%) of such Sales Forecast. All other purchase orders must be
         accepted or rejected by SuperGen, in writing, by facsimile or air
         courier, within fifteen (15) business days after receipt from Abbott.
         If SuperGen does not provide such notice of acceptance or rejection
         within fifteen (15) business days, it shall be deemed to have accepted
         such purchase orders in full. SuperGen shall deliver all accepted
         orders to Abbott promptly and shall deliver Abbott's first order for
         Finished Product to be sold in the U.S. Territory and the International

         accordance with this Article 8, Abbott shall use its reasonable efforts
         to maintain adequate inventories of the Finished Product in the
         Territories to meet the needs of its customers on a timely basis based
         upon, among other factors, the Sales Forecast, previous demand
         histories and seasonal trends, and any customers' contractual
         commitments. SuperGen shall use its reasonable efforts to maintain
         adequate inventories of Finished Product to meet the needs of Abbott on
         a timely basis, including but not limited to ensuring that any Third
         Party manufacturer shall maintain at least thirty (30) days' worth of
         Finished Product in inventory.

         (b) In the event that SuperGen (or its designated Third Party
         manufacturer(s)) are unable to fill accepted orders for the Finished
         Product placed by Abbott pursuant to this Agreement for a total of four
         (4) months, whether or not consecutive, in any twelve (12) month
         period, Abbott may at its sole option: (i) forgo the quantities ordered
         which SuperGen is unable to supply; (ii) take delivery within a
         reasonable period of time after SuperGen becomes able to supply the
         quantities ordered; or (iii) make or have a Third Party make, or permit
         SuperGen to have a Third Party (approved by Abbott) make, the Finished
         Product.

                                                                              36

         (c) In the event that a visit or report by an authorized agent of a
         governmental agency in the Territories, or a visit by an outside
         independent quality assurance auditor acceptable to both Parties,
         reveals that SuperGen's (or SuperGen's Third-Party manufacturer's)
         facilities and processes for manufacturing the Compound, the Product or
         the Finished Product do not comply with applicable laws and
         regulations, including without limitation Current Good Manufacturing
         Practices, and if SuperGen does not rectify the situation to Abbott's
         reasonable satisfaction within sixty (60) days of Abbott's notice to
         SuperGen of such situation, then Abbott may make or have a Third Party
         make, or permit SuperGen to have a Third Party (approved by Abbott)
         make the Compound, the Product and/ or the Finished Product.

         (d) In the event Abbott elects to make or have made the Compound, the
         Product and/ or the Finished Product pursuant to Article 8.5(b) or (c)
         above, SuperGen shall (i) transfer to Abbott or Abbott's or SuperGen's
         designated Third Party all information and authorizations useful and
         necessary with respect to the manufacture, storage and shipment of the
         Compound, the Product and/ or the Finished Product, in a timely manner
         so as to avoid any delay or interruption in supply of Finished Product
         to Abbott, and (ii) reimburse Abbott for that portion of the cost of
         manufacturing or having such Third Party manufacture and supply the
         Compound, the Product, and/ or the Finished Product which is in excess
         of the applicable Transfer Price.

8.6      CUSTOMER RELATIONS.

         (a) With respect to customer complaints relating to the Promotion or
         distribution of the Product, each Party shall act promptly to remedy
         such complaints. All Product-related inquiries and Product complaints
         in the U.S. Territory shall be addressed by SuperGen, and all
         Product-related inquiries and Product complaints in the International
         Territory shall be addressed by Abbott. Each Party shall keep the other
         Party fully and promptly apprised of its receipt of any such
         significant complaints in the Territories, and provide reasonable
         cooperation and assistance in dealing with customer complaints in the
         Territories, the verifiable out-of-pocket cost of such cooperation and
         assistance being borne by SuperGen in the U.S. Territory and by Abbott
         in the International Territory.

         (b) Any Product warranty to the customers of Abbott and SuperGen shall
         run directly from SuperGen to such customers, notwithstanding the fact
         that Abbott's customers may return Product to Abbott and not to
         SuperGen. Abbott shall not make any warranty or representation to any
         customers which is more protective of such customers than the
         warranties and/ or representations provided by SuperGen. For purposes
         of clarification, the sole remedy of Abbott and/ or SuperGen customers
         in the case of defective Product shall be that the Party which sold the
         defective Product to the customer shall replace such returned defective
         Product. SuperGen's Product warranties shall not apply to Product that
         has been modified

                                                                             37

         their respective Affiliates or subdistributors or sublicensees), or to
         defects caused (i) through no fault of SuperGen SuperGen or Abbott (or
         their respective Affiliates or subdistributors or sublicensees), during
         shipment, (ii) by negligence or misuse on the part of anyone other than
         SuperGen or Abbott (or their respective Affiliates or subdistributors

         inconsistent with the approved Product labeling.

         (c) Neither Party shall represent the Product in any manner which is
         inconsistent with the approved Product labeling or with applicable laws
         and regulations, or otherwise misrepresent the Product.

accordance with, and shall comply with, applicable laws and regulations and
generally accepted industry standards (including cGMPs as defined below) for
the manufacture, storage, shipment, handling and distribution of the

         of any such defect or shortage, SuperGen shall, at SuperGen's choice,
         replace the defective Finished Product or make up the shortage if
         replacement stock is available in the next shipment of Finished
         Product, but in any case no later than twenty (20) days or, if no such
         replacement stock is available, as soon as reasonably practical after
         receiving such notice, at no additional cost to Abbott.

         (d) With respect to all SuperGen Third Party manufacturers of the
         Compound, the Product, and the Finished Product, SuperGen shall provide

         and any other Third Party license agreements or other agreements
         relating to the Product to which SuperGen is a Party or becomes a Party
         during the term of this Agreement (collectively, the "SuperGen License

         License Agreements relating to the

                                                                              39

         Product which would or could otherwise trigger termination of any such
         Agreements (e.g., bankruptcy, change of control in whole or with
         respect to any part of the Territories) or which would or could cause
         the conversion of any SuperGen License Agreement from an exclusive to
         nonexclusive agreement, in whole or with respect to any part of the
         Territories;

         (c) notify Abbott in the event that, and within three (3) business days
         after, SuperGen receives notice from any of SuperGen's licensors that
         SuperGen is in default under any SuperGen License Agreement relating to
         the Product or that any such SuperGen licensor has terminated or
         intends to terminate any SuperGen License Agreement in whole or with
         respect to any part of the Territories or convert any SuperGen License
         Agreement from an exclusive to non-exclusive agreement in whole or with
         respect to any part of the Territories, or otherwise take any action in
         connection with a SuperGen License Agreement which would adversely
         affect Abbott's rights under this Agreement. In the event of any
         default of the type described in this Section 9.2(c), SuperGen agrees
         that if it fails or does not intend to cure such default, Abbott may,
         at Abbott's option and to the extent permitted under the applicable
         license agreement, do so and may offset against SuperGen's share of the
         U.S. Product Profit and the royalty payable to SuperGen by Abbott
         pursuant to Article 7 above, as applicable, any reasonable expenses
         Abbott incurs in curing such default, except for any portion of such
         expenses that would have otherwise been included as part of Third Party
         Royalties. Abbott and SuperGen shall account for such portion of
         expense as a SuperGen Third Party Royalty;

         (d) provide Abbott with a copy of any reports, correspondence or notice
         within three (3) business days from the submission to or receipt from
         Stehlin or any other Third Party licensor under any SuperGen License
         Agreement.

         (e) notify Abbott no later than thirty (30) days prior to implementing
         any decision to abandon or allow to lapse any patent application or
         patent or not to initiate or take any other patent prosecution activity
         with respect to any Product Patent. In such event, SuperGen agrees that
         Abbott may assume any such patent prosecution activity in connection
         therewith, and SuperGen shall reasonably cooperate with Abbott in
         connection with any such patent prosecution activity and, if requested
         by Abbott, shall use its reasonable efforts to seek the cooperation of
         Stehlin or any other Third Party licensor; and

         (f) take no action nor will it omit to take any action which would
         result in derogation of the Licensed Patents in any existing or future
         litigation or interference with any Third Parties or future oppositions
         to foreign patents of any Third Parties.

9.3     THIRD PARTY INFRINGEMENT. If Abbott or SuperGen become aware of any
        activity on the part of any Third Party that such Party believes
        infringes a Valid Claim of a Licensed Patent, such Party shall promptly
        notify the other Party of all relevant

                                                                              40

        facts and circumstances pertaining to the potential infringement.
        SuperGen shall have the right to enforce any rights within the Licensed
        Patents against such infringement, at its own cost and expense. Abbott,
        at its own expense, shall cooperate with SuperGen in such effort,
        including but not limited to being joined as a Party to such action,
        and SuperGen shall use its reasonable efforts to obtain the cooperation
        of Stehlin and any other Third Party licensor in connection with such
        enforcement.

9.4     ABBOTT'S RIGHT TO PURSUE THIRD PARTY INFRINGERS. If SuperGen shall fail,
        within the lesser of (i) ninety (90) days of the notice of infringement
        required by Section 9.3 or (ii) one-half the period of time allowed
        therefor under the applicable SuperGen License Agreement, to either (A)
        terminate such infringement or (B) institute an action seeking to
        prevent continuation thereof, and thereafter to diligently prosecute
        such action, or if SuperGen sooner notifies Abbott that it does not plan
        to terminate the infringement or institute such action, then Abbott
        shall have the right to do so at its own expense. SuperGen, at its own
        expense, shall cooperate in such effort, including being joined as a
        Party to such action, and SuperGen shall use its reasonable efforts to
        obtain the cooperation of Stehlin and any other Third Party licensor.


9.5     ALLOCATION OF DAMAGE OR SETTLEMENT AMOUNTS. Any damage award or
        settlement obtained by a Party enforcing a Licensed Patent pursuant to
        Article 9.3 or 9.4 above shall first be used to reimburse the enforcing
        Party and then shall shared equally between the Parties.

of information in or coming into its possession or control concerning side
effects, injury, toxicity or sensitivity reaction and incidents of severity
thereof associated with commercial and clinical uses, studies, investigations or
tests of each Product in the Territories, whether or not determined to be
attributable to the Product. SuperGen shall be responsible for filing with the
FDA, as required pursuant to 21 C.F.R. Sec. 314.80, any adverse reaction reports
that it receives. Abbott shall be responsible for filing with the appropriate
regulatory authorities in the International Territory, as required, adverse
reaction reports that it receives. Within four (4) months of the Effective Date,
the respective pharmacovigilance groups of SuperGen and Abbott shall enter into
a separate agreement covering adverse event information exchange relating to the
Product.

10.2 SAFETY ISSUES. In order to ensure that both Parties are provided with an
adequate opportunity to review safety matters, the Parties shall mutually agree
after the Effective Date on procedures with respect to (i) regulatory reporting
requirements, (ii) the review of Product labeling, (iii) maintenance of a safety
database and (iv) other safety issues.


                                                                              41

10.3     PRODUCT COMPLAINTS AND INQUIRIES.

         (a) Any medical or technical Product-related inquiries from consumers,
         physicians or other Third Party customers who reside in the (i) U.S.
         Territory shall be handled by SuperGen and (ii) International Territory
         shall be handled by Abbott. SuperGen shall supply Abbott with copies of
         its standard response information for the Product as well as any
         updates thereto. Abbott shall use such information to respond to any
         such inquiries from the International Territory. Each Party shall
         prepare and maintain a database containing responses to such inquiries
         from consumers, physicians or other Third Party customers who reside in
         the territory for which it is responsible, and shall make the contents
         available to the other Party promptly from time to time upon request.

         (b) Each Party shall maintain a record of all complaints or reports of
         an actual or potential failure of any Product to meet the
         specifications set forth in regulatory filings or in agreements among
         the Parties. Such failure may involve the finished Product or one of
         its intermediate stages. The responsibilities of the Parties with
         respect to (a) notification of the product complaint from the receiving
         Party to the other Party and (b) the handling of product complaints
         shall all be performed in accordance with a procedure to be mutually
         agreed by the Parties after the Effective Date.

10.4 PRODUCT RECALL. In the event that either Party determines that an event,
incident or circumstance has occurred which may result in the need for a recall
or other removal of any Product, or any lot or lots thereof, from the market in
any part or all of the Territories, such Party shall advise the other Party and
the Parties shall consult with respect thereto. SuperGen shall have the sole
authority to decide whether to commence, and the sole responsibility for the
handling and disposition of, a recall or other removal of such Product in the
U.S. Territory, and Abbott shall have the sole authority to decide whether to
commence, and the sole responsibility for the handling and disposition of, a
recall or other removal of such Product in the International Territory. Any such
recall or other removal, by either Party, shall occur pursuant to a procedure to
be mutually agreed by the Parties after the Effective Date. Except as provided
below, if a Product (or any lot or lots thereof) is recalled or otherwise
removed from the market, the costs and expenses of such recall or removal,
including, without limitation, expenses and other costs or obligations to Third
Parties, the cost and expense of notifying customers and the costs and expenses
associated with shipment of the recalled Product and the cost and expense of
destroying the Product removed from the market, if necessary, except as provided
below shall be borne by SuperGen to the extent such expenses relate to the U.S.
Territory and shall be shared equally by SuperGen to the extent such expenses
relate to the International Territory. In the event that such recall or removal
costs, expenses or obligations result from one Party's: (i) improper or
negligent manufacturing, distribution, storage or shipment of the Product; .(ii)
improper sampling practices or mishandling of Sample Packs; (iii) Co-Promotion
or Promotion of the Product in a manner inconsistent with the Product's
labeling; or (iv) violation of this Agreement, such costs, expenses and


                                                                              42

10.5 GOVERNMENTAL CONTACT REPORTING . Each Party shall promptly notify the other
Party upon being contacted by the FDA or any other competent governmental
authority or agency in the Territories for any material regulatory purpose
pertaining to this Agreement or to the Product. Neither Party shall respond to
the FDA or such other authority or agency before consulting with the other
Party, unless under the circumstances pursuant to which FDA or such other
authority or agency contacts such Party, it is not practical or lawful for the
contacted Party to give the other Party advance notice, in which event the
contacted Party shall inform the other Party of such contact as soon as
practical and lawful. In addition, each Party shall keep the other Party advised
with respect to information concerning the safety or efficacy of the Product,
including but not limited to providing, within three (3) business days of the
creation or receipt thereof, all information regarding such safety, efficacy and
medical information issues and copies of safety reports filed with the FDA or
any other authority or agency.

the failure to so mark shall not exclude such written information from the
provisions of this Section 13. "Confidential Information" shall not include
information:

         (a) which is or becomes generally available to the public other than as
         a result of unauthorized disclosure thereof by the Receiving Party;

         (b) which is lawfully received by the Receiving Party on a
         nonconfidential basis from a Third Party that is not itself under any
         obligation of confidentiality or nondisclosure to the Disclosing Party
         or any other Person with respect to such information;

         (c) which by written evidence can be shown by the Receiving Party to
         have been independently developed by or for the Receiving Party; or

         (d) which the Receiving Party establishes by competent proof was in its
         possession at the time of disclosure by the other Party and was not
         acquired, directly or indirectly from the other Party under any
         obligation of confidentiality.

All information, data and other materials disclosed by one Party to the other
pursuant to the Confidentiality Agreement, dated May 2, 1999, shall be deemed to
have been disclosed by the disclosing Party under this Agreement.

13.2     NONDISCLOSURE OF CONFIDENTIAL INFORMATION. The Receiving Party shall
use Confidential Information solely for the purposes of this Agreement and
shall not disclose or disseminate any Confidential Information to any Third
Party at any time without the Disclosing Party's prior written consent,
except for disclosure to those of its directors, officers, employees,
accountants, attorneys, advisers, permitted sublicensees, agents and


                                                                              47

representatives whose duties reasonably require them to have access to such
Confidential Information, provided that such directors, officers, employees,
accountants, attorneys, advisers, agents and representatives are required to
use the Confidential Information solely for purposes of this Agreement and
maintain the confidentiality of such Confidential Information to the same
extent as if they were Parties hereto.

13.3     EXCEPTION. The foregoing confidentiality and nondisclosure
obligations shall not apply to information which is required to be disclosed
by law or by regulation; provided, that (i) the Receiving Party gives the
Disclosing Party reasonable advance notice of the disclosure, to the extent
reasonably practicable and legally permissible; (ii) the Receiving Party uses
reasonable efforts to resist disclosing the Confidential Information; (iii)
the Receiving Party reasonably cooperates with the Disclosing Party on
request to obtain a protective order or otherwise limit the disclosure; and
(iv) upon the reasonable request of the Disclosing Party, the Receiving Party
shall provide a letter from its counsel confirming that the Confidential
Information is, in fact, required to be disclosed.

13.4     INJUNCTIVE RELIEF. The Parties acknowledge that either Party's
breach of this Article 13 may cause the other Party irreparable injury for
which it would not have an adequate remedy at law. In the event of a breach,
the non-breaching Party shall be entitled to injunctive relief in addition to
any other remedies it may have at law or in equity.

13.5     SURVIVAL. The confidentiality and nondisclosure obligations of this
Article 13 shall survive the expiration or termination of this Agreement and
remain in effect for a period of ten (10) years following the expiration or
termination of this Agreement.

registration and maintenance of the SuperGen Trademark(s) in the U.S.

                                                                              48
<PAGE>

                                              CONFIDENTIAL TREATMENT REQUESTED

registration and maintenance of the Abbott Trademark(s) in the International
Territory. Abbott shall keep SuperGen fully apprised with respect to the its
trademark activities and shall consult with SuperGen regarding the selection
of the Abbott Trademark(s) for the International Territory. Abbott shall
control all final decisions regarding the Abbott Trademarks.

14.4     LIMITED TRADEMARK LICENSE. In the event that Abbott's rights under
this Agreement shall cease, and upon request by SuperGen, Abbott shall grant
to SuperGen an exclusive limited license in the International Territory to
use the Abbott Trademark(s), solely for the purpose of promoting distributing
and selling the Product in the International Territory. SuperGen shall pay
Abbott a trademark royalty of two percent (2%) of SuperGen's Net Sales of the
Product in the International Territory, subject to the terms of a separate
trademark license to be entered into by the Parties.

14.5     USE OF TRADE NAMES AND LOGOS. Each Party recognizes that the name
and logo of each of the Parties represents a valuable asset of such entity
and that substantial recognition and goodwill are associated with each
Party's name, and logo. Each Party hereby agrees that, without prior written
authorization of the other Party, it shall not use the name or logo of the
other Party for any purpose other than the promotion, distribution and sale
of the Product solely to the extent required to fulfill its obligations under
this Agreement. In addition, SuperGen shall only use the Abbott name and logo
in the form, manner and logotype approved in writing by Abbott, and Abbott
shall only use the SuperGen name and logo and the SuperGen Trademarks in the
form, manner and logotype approved in writing by SuperGen. Except for the
limited license granted in Section 14.2 above, nothing in this Agreement
shall be construed as an assignment by SuperGen to Abbott of any right, title
or interest in or to the SuperGen name or logo or the SuperGen Trademarks, or
an assignment by Abbott to SuperGen of any right, title or interest in or to
the Abbott name or logo or the Abbott Trademarks; it being understood that
all right, title and interest (including the goodwill associated therewith)
in and to the SuperGen name and logo and the SuperGen Trademark(s) is
expressly reserved by SuperGen, and all right, title and interest (including
the goodwill associated therewith) in and to the Abbott name and logo and the
Abbott Trademarks is expressly reserved by Abbott.

14.6     INJUNCTIVE RELIEF. Each Party acknowledges that a violation of this
Article 14 would cause irreparable harm to the other Party for which no
adequate remedy at law exists, and each Party therefore agrees that, in
addition to any other remedies available, and notwithstanding any other
provision in this Agreement, the aggrieved Party shall be entitled to
injunctive relief to enforce the terms of this Article 14. If either Party
prevails in any such action, it shall be entitled to recover all costs and
expenses, including reasonable attorney's and other professional fees and
expenses incurred because of any legal action arising in relation to this
Article 14.

14.7     NOTIFICATION OF INFRINGEMENT AND ENFORCEMENT. Each Party shall
notify the other Party of any infringement or misuse of SuperGen's
Trademark(s) of which such Party becomes aware. SuperGen shall be solely
responsible to prosecute any infringement of


                                                                              49

SuperGen's cost and expenses of enforcement, shall be shared equally between
the Parties.

ARTICLE 15:  INDEMNIFICATION

15.1     INDEMNIFICATION BY SUPERGEN. Except as may be otherwise provided
herein, SuperGen shall defend, indemnify and hold Abbott, all of its
directors, officers and employees, and Abbott Sales Representatives
(collectively the "Abbott Indemnitees") harmless from and against all Losses
incurred in connection with any Third Party suits, claims or causes of action
arising out of or resulting from:

         (a) SuperGen's breach of any representation, warranty, covenant, or
         obligation provided for in this Agreement;

         (b) an infringement claim arising from Abbott's use of the SuperGen
         name or logo or a SuperGen Trademark in connection with the promotion
         or sale of the Products, provided Abbott's use is in compliance with
         the terms of this Agreement;

         (c) the negligence, recklessness or willful misconduct of SuperGen and
         its directors, officers or employees or SuperGen Sales Representatives,
         including, but not limited to, product liability claims arising out of
         off-label promotions by SuperGen, its directors, officers, employees or
         SuperGen Sales Representatives; or

         (d) any patent infringement claim arising from the manufacture,
         importation, use or sale of the Product.

Provided, however, that SuperGen shall not be required to indemnify the Abbott
Indemnitees to the extent that any Losses arise out of or result from: (A) the
negligence, recklessness or willful misconduct of any of the Abbott Indemnitees,
including, but not limited to, off-label promotion of the Product, (B)
utilization of process technology for the manufacture of Product which has not
been approved by SuperGen, (C) continued Promotion in a country after receipt of
notice from SuperGen indicating that the sale or Promotion of such Product in
such country should be terminated because such further sale or Promotion would
constitute willful infringement of a valid and issued patent in such country
and/or (D) any breach by Abbott of this Agreement. Abbott shall not be
considered negligent for purposes of this Section 15.1 if such claim arises
solely with respect to the content of the Promotional Materials, Product
labeling or other materials provided to Abbott by SuperGen as long as Abbott has
distributed or employed such Promotional Materials or other such materials as
directed herein.

15.2 INDEMNIFICATION BY ABBOTT . Except as may be otherwise provided herein,
Abbott shall defend, indemnify and hold SuperGen, its directors, officers and
employees, and SuperGen Sales Representatives (collectively the "SuperGen
Indemnitees") harmless from and against all Losses incurred in connection with
any Third Party suits, claims or


                                                                              50
<PAGE>

                                                CONFIDENTIAL TREATMENT REQUESTED

causes of action arising out of or resulting from:

         (a) Abbott's breach of any representation, warranty, covenant, or
         obligation provided for in this Agreement;

         (b) an infringement claim arising from SuperGen's use of the Abbott
         name or logo in connection with the promotion or sale of the Product,
         provided SuperGen's use is in compliance with the terms of this
         Agreement;

         (c) the negligence, recklessness or willful misconduct of Abbott, its
         directors, officers or employees or Abbott Sales Representatives,
         including, but not limited to, product liability claims arising out of
         off-label promotions by Abbott, its Affiliates, their directors,
         officers or employees, or Abbott Sales Representatives; or

         (d) any patent infringement claim arising from Abbott's or its
         Affiliates' or permitted sublicensee's (A) utilization of process
         technology for the manufacture of the Product which has not been
         approved by SuperGen or (B) continued Promotion in a country after
         receipt of notice from SuperGen indicating that the sale or Promotion
         of such Product in such country should be terminated because such
         further sale or Promotion would constitute willful infringement of a
         valid and issued patent in such country.

Provided, however, that Abbott shall not be required to indemnify the SuperGen
Indemnitees to the extent that any Losses arise out of or result from: (A) the
negligence, recklessness or willful misconduct of any SuperGen Indemnitee
including, but not limited to, off-label promotion of the Product; and/or (B)
any breach by SuperGen of this Agreement.

15.3 INDEMNIFICATION PROCEDURE. Any Abbott Indemnitee or SuperGen Indemnitee, as
the case may be, shall notify SuperGen or Abbott (the "Indemnifying Party")
promptly in writing of an indemnifiable claim or cause of action under Article
15.1 or 15.2 upon receiving notice or being informed of the existence thereof.
The Indemnifying Party shall assume, at its cost and expense, the sole defense
of such claim or cause of action through counsel selected by the Indemnifying
Party and reasonably acceptable to the other Party. The Indemnifying Party shall
maintain control of such defense, including any decision as to settlement;
provided that:

         (a) the Indemnifying Party shall not enter into any binding settlement,
         consent to any judgment, or otherwise resolve any such claim or action
         pursuant to which the other Party would be obligated to take or refrain
         from taking any action (including but not limited to being enjoined
         from making, using, importing, selling or offering to sell the Product)
         or to make any payments or admissions, without the other Party's prior
         written consent; and

         (b) in the event that the Indemnifying Party does not diligently defend
         such


                                                                             51
<PAGE>

                                                CONFIDENTIAL TREATMENT REQUESTED

         claim or cause of action on a timely basis, then, without prejudice to
         any other rights and remedies available to the other Party under this
         Agreement, the other Party may take over such defense with counsel of
         its choosing at the Indemnifying Party's cost and expense.  The other
         Party may, at its option and expense, participate in the Indemnifying
         Party's defense, and if the other Party so participates, the Parties
         shall cooperate with one another in such defense. The Indemnifying
         Party shall bear the total costs of any court award or settlement of
         such claim or cause of action and all other costs, fees and expenses
         related to the resolution thereof (including reasonable attorney's and
         other professional fees and expenses except for attorneys' fees for
         which the other Party is responsible in the event that the other Party
         participates in the Indemnifying Party's defense of such claim or cause
         of action). The indemnification obligations herein shall apply on a
         first dollar basis without limitation or reduction due to any
         deductible or self-insured retention which SuperGen or Abbott
         respectively may have under their respective insurance coverage.

15.4 PRODUCT LIABILITY. In the event of a product liability claim with respect
to the Product which is not covered by the foregoing indemnity provisions in
this Article 15, the Parties shall bear equally the amount of any awards or
other losses and costs attributable directly thereto. Abbott shall maintain
control of the defense of any such product liability claim with respect to the
International Territory and SuperGen shall maintain control of the defense of
any such product liability claim with respect to the U.S. Territory.

ARTICLE 16: TERM AND TERMINATION

16.1 TERM. The term of this Agreement shall commence on the Effective Date and,
unless terminated sooner in accordance with this Article 16:

         (a) for the U.S. Territory, the term of this Agreement shall expire
         upon the earlier of (i) the date upon which a generic version of the
         Product is first sold in the U.S. Territory, or (ii) the date which is
         fifteen (15) years after the date of Regulatory Approval of the Product
         in the U.S. Territory, provided that the Parties may renew this
         Agreement for the U.S. Territory for (i) further successive one (1)
         year periods, or (ii) further successive periods of time during which
         any applicable marketing exclusivity precludes the effective approval
         by the FDA of any product containing the Compound, upon written
         agreement made no later than thirty (30) days prior to the end of the
         original term and any succeeding extensions thereof; and

         (b) for the International Territory, the term of this Agreement shall
         expire upon the later of (i) the date which is fifteen (15) years after
         the date of Regulatory Approval of the Product in the first country
         within the International Territory, and (ii) the date upon which the
         last Valid Claim expires or is found invalid or unenforceable by the
         final, unappealable or unappealed decision of a court or other entity
         of competent jurisdiction.


                                                                             52
<PAGE>

                                                CONFIDENTIAL TREATMENT REQUESTED

16.2     Upon expiration of this Agreement in the International Territory,
         Abbott shall have a fully-paid up, irrevocable license to use and sell
         the Product in the International Territory under the SuperGen
         Technology.

16.3     TERMINATION FOR MATERIAL BREACH. Either party may, in addition to any
         other remedies available to it by law or in equity, terminate this
         Agreement, upon sixty (60) days' written notice in the event that the
         other party breaches a material provision of this Agreement and fails
         to cure such breach within sixty (60) days of notice of the breach. The
         party giving notice of breach may withhold any payments otherwise due
         and owing to the breaching party, to be used as a setoff against any
         loss or damage arising from the breach, and such withholding shall not
         constitute breach of this Agreement. If the breaching party cures the
         breach within the sixty (60) day cure period and this Agreement is not
         terminated, then the withholding party shall promptly pay to the other
         party the withheld amount, less that portion of such amount which was
         applied as a setoff. Notwithstanding the foregoing provision, if Abbott
         gives notice of breach to SuperGen, Abbott may withhold other payments
         pursuant to this Article 16.3 but shall not be entitled to withhold
         payment for Finished Product actually ordered from and delivered and
         invoiced by SuperGen pursuant to Article 8 of this Agreement.


16.4     TERMINATION FOR NON-APPROVAL OR LACK OF COMMERCIAL VIABILITY.

         (a) Commencing one (1) year after the Effective Date, Abbott may
         terminate this Agreement at any time, on a Territory-by-Territory basis
         or in whole, upon thirty (30) days written notice to SuperGen that (i)
         the Product has not obtained Regulatory Approval in the U.S. Territory
         and/ or in one or more of the Major European Countries (as the case may
         be), or (ii) Abbott, in the exercise of its reasonable commercial
         judgment, has determined that the Product and/ or the material terms
         and conditions of this Agreement are not commercially viable.

         (b) Commencing on the Effective Date, Abbott may terminate this
         Agreement at any time, on a Territory-by-Territory basis or in whole,
         upon thirty (30) days written notice to SuperGen in the event that the
         milestones defined in Article 5.1(c)(i) above are not met by June 30,
         2000.

16.5     BANKRUPTCY OR INSOLVENCY. Either Party may, in addition to any other
         remedies available to it by law or in equity, terminate this Agreement,
         upon thirty (30) days' written notice to the other Party in the event
         the other Party shall have become insolvent or bankrupt, or shall have
         made an assignment for the benefit of its creditors, or there shall
         have been appointed a trustee or receiver of the other Party or for all
         or a substantial Party of its property, or any case or proceeding shall
         have been commenced or other action taken by or against the other Party
         in bankruptcy or seeking reorganization, liquidation, dissolution,
         winding-up, arrangement, composition or readjustment of its debts or
         any relief under any bankruptcy, insolvency, reorganization or other
         similar act or law of any


                                                                             53
<PAGE>

                                                CONFIDENTIAL TREATMENT REQUESTED

         jurisdiction now or hereinafter in effect (an "Insolvency Event").
         However, in the event that SuperGen experiences an Insolvency Event and
         any trustee acting on behalf of SuperGen or its debtors rejects this
         Agreement, Abbott shall have the right to elect to retain its rights
         under this Agreement upon written notification to said trustee of its
         intentions to do so. All rights and licenses granted hereunder are for
         all purposes of this Agreement licenses of rights to intellectual
         property and may not be terminated upon an Insolvency Event without the
         express agreement of the Party that is not insolvent. Notwithstanding
         anything to the contrary in this Agreement, in the event that SuperGen
         experiences an Insolvency Event and Abbott does not elect to terminate
         this Agreement, then Abbott shall automatically have the right to make,
         in its sole discretion, any decisions relating to the clinical
         development of the Product, regulatory strategies and tactics for the
         Product, and the marketing, promotion and sale of the Product which
         decisions were heretofore to be made either jointly by the Parties or
         solely by SuperGen under this Agreement.

16.6 SERIOUS EVENTS. Should there occur serious and unexpected events which,
from a reasonable pharmaceutical company's point of view, would make it
impossible or impracticable to pursue the commercialization of the Product,
including but not limited to (i) a serious adverse event associated with the
Compound and/ or the Product or (ii) infringement of any Third Party
intellectual property rights by the manufacture, importation, use or sale of the
Product, either Party may terminate this Agreement upon thirty (30) days'
written notice.

16.7 CHANGE OF CONTROL OR OWNERSHIP. Either Party may terminate this Agreement
upon thirty (30) days' written notice if the ownership or control of at least
fifty percent (50%) of the assets or voting securities of the other Party are
transferred and, in the non-changing Party's reasonable judgement, the other
Party's new owner or controlling entity is a competitor of the non-changing
Party in the field of oncology. In addition to this right, if fifty per cent
(50%) or more of SuperGen's assets or if the ownership of the controlling
interest in SuperGen becomes subject to the control of persons not presently
owners of SuperGen, then within thirty (30) days of receipt of notice to Abbott
from SuperGen of such a change in control, Abbott may request from such
controlling persons a written affirmation that the same level of time, money,
personnel and other resources devoted by SuperGen to meet its obligations under
the terms and conditions of this Agreement prior to the change of control will
be available to SuperGen to meet its obligations under the terms and conditions
of this Agreement after the change of control. If the controlling persons do not
provide such written affirmation to Abbott within thirty (30) days after the
date of Abbott's request, then Clause 20.3 of this Agreement shall automatically
be amended to provide that a dispute between the Parties that cannot be resolved
by reference to the appropriate Divisional Presidents of Abbott and the
President of SuperGen, will be resolved in Abbott's favor.

16.8 EFFECT OF TERMINATION.


                                                                             54

                                                CONFIDENTIAL TREATMENT REQUESTED

         (a) Any termination with respect to a particular Territory shall only
         result in the termination of rights and obligations hereunder as they
         relate to that Territory.

         (b) Expiration or termination of this Agreement (on a
         Territory-by-Territory basis or as a whole) shall not release any Party
         from liability accrued under this Agreement prior to such expiration or
         termination, nor preclude either Party from pursuing any rights or
         remedies accrued prior to such expiration or termination or accrued at
         law or in equity with respect to any breach of this Agreement.

         (c) Termination of this Agreement (on a Territory-by-Territory basis or
         as a whole) in good faith by any Party shall not in itself constitute
         any basis for claims for compensation, damages (direct, indirect or
         consequential) or any other remedy in law or at equity by the other
         Party, including but not limited to any claim for lost sales, profits,
         goodwill or business opportunity or any claim on account of
         expenditures, investments or commitments made in connection with the
         Product or the Agreement.

                         ALTERNATIVE DISPUTE RESOLUTION


                  The parties recognize that bona fide disputes as to certain
                  matters may arise from time to time during the term of this
                  Agreement which relate to either Party's rights and/or
                  obligations. To have such a dispute resolved by this
                  Alternative Dispute Resolution ("ADR") provision, a Party
                  first must send written notice of the dispute to the other
                  Party for attempted resolution by good faith negotiations
                  between their respective presidents (or their designees) of
                  the affected subsidiaries, divisions, or business units within
                  twenty-eight (28) days after such notice is received (all
                  references to "days" in this ADR provision are to calendar
                  days).

                  If the matter has not been resolved within twenty-eight (28)
                  days of the notice of dispute, or if the parties fail to meet
                  within such twenty-eight (28) days, either Party may initiate
                  an ADR proceeding as provided herein. The parties shall have
                  the right to be represented by counsel in such a proceeding.

                  1. To begin an ADR proceeding, a Party shall provide written
                  notice to the other Party of the issues to be resolved by ADR.
                  Within fourteen (14) days after its receipt of such notice,
                  the other Party may, by written notice to the Party initiating
                  the ADR, add additional issues to be resolved within the same
                  ADR.

                  2. Within twenty-one (21) days following receipt of the
                  original ADR notice, the parties shall select a mutually
                  acceptable neutral to preside in the resolution of any
                  disputes in this ADR proceeding. If the parties are unable to
                  agree on a mutually acceptable neutral within such period,
                  either Party may request the President of the CPR Institute
                  for Dispute Resolution ("CPR"), 366 Madison Avenue, 14th
                  Floor, New York, New York 10017, to select a neutral pursuant
                  to the following procedures:

                           (a) The CPR shall submit to the parties a list of not
                  less than five (5) candidates within fourteen (14) days after
                  receipt of the request, along with a CURRICULUM VITAE for each
                  candidate. No candidate shall be an employee, director, or
                  shareholder of either Party or any of their subsidiaries or
                  affiliates.

                                                                              74
<PAGE>
                                                CONFIDENTIAL TREATMENT REQUESTED


                           (b) Such list shall include a statement of disclosure
                  by each candidate of any circumstances likely to affect his or
                  her impartiality.

                           (c) Each Party shall number the candidates in order
                  of preference (with the number one (1) signifying the greatest
                  preference) and shall deliver the list to the CPR within seven
                  (7) days following receipt of the list of candidates. If a
                  Party believes a conflict of interest exists regarding any of
                  the candidates, that Party shall provide a written explanation
                  of the conflict to the CPR along with its list showing its
                  order of preference for the candidates. Any Party failing to
                  return a list of preferences on time shall be deemed to have
                  no order of preference.

                           (d) If the parties collectively have identified fewer
                  than three (3) candidates deemed to have conflicts, the CPR
                  immediately shall designate as the neutral the candidate for
                  whom the parties collectively have indicated the greatest
                  preference. If a tie should result between two candidates, the
                  CPR may designate either candidate. If the parties
                  collectively have identified three (3) or more candidates
                  deemed to have conflicts, the CPR shall review the
                  explanations regarding conflicts and, in its sole discretion,
                  may either (i) immediately designate as the neutral the
                  candidate for whom the parties collectively have indicated the
                  greatest preference, or (ii) issue a new list of not less than
                  five (5) candidates, in which case the procedures set forth in
                  subparagraphs 2(a) - 2(d) shall be repeated.

                  fifty-six (56) days after selection, the neutral shall hold a
                  hearing to resolve each of the issues identified by the
                  parties. The ADR proceeding shall take place at a location
                  agreed upon by the parties. If the parties cannot agree, the
                  neutral shall designate a location other than the principal
                  place of business of either Party or any of their subsidiaries
                  or affiliates.

                  4. At least seven (7) days prior to the hearing, each Party

                  call at the hearing, and a short summary of the anticipated
                  testimony of each witness;

                                                                              75

                                               CONFIDENTIAL TREATMENT REQUESTED

                           (c) a proposed ruling on each issue to be resolved,
                  together with a request for a specific damage award or other
                  remedy for each issue. The proposed rulings and remedies shall
                  not contain any recitation of the facts or any legal arguments
                  and shall not exceed one (1) page per issue.

                           (d) a brief in support of such Party's proposed
                  rulings and remedies, provided that the brief shall not exceed
                  twenty (20) pages. This page limitation shall apply regardless
                  of the number of issues raised in the ADR proceeding.

                  Except as expressly set forth in subparagraphs 4(a) - 4(d), no
                  discovery shall be required or permitted by any means,
                  including depositions, interrogatories, requests for
                  admissions, or production of documents.

                  5. The hearing shall be conducted on two (2) consecutive days
                  and shall be governed by the following rules:

                           (a) Each Party shall be entitled to five (5) hours of
                  hearing time to present its case. The neutral shall determine
                  whether each Party has had the five (5) hours to which it is
                  entitled.

                           (b) Each Party shall be entitled, but not required,
                  to make an opening statement, to present regular and rebuttal
                  testimony, documents or other evidence, to cross-examine
                  witnesses, and to make a closing argument. Cross-examination
                  of witnesses shall occur immediately after their direct
                  testimony, and cross-examination time shall be charged against
                  the Party conducting the cross-examination.

                           (c) The Party initiating the ADR shall begin the
                  hearing and, if it chooses to make an opening statement, shall
                  address not only issues it raised but also any issues raised
                  by the responding Party. The responding Party, if it chooses
                  to make an opening statement, also shall address all issues
                  raised in the ADR. Thereafter, the presentation of regular and
                  rebuttal testimony and documents, other evidence, and closing
                  arguments shall proceed in the same sequence.

                           (d) Except when testifying, witnesses shall be
                  excluded from the hearing until closing arguments.

                           (e) Settlement negotiations, including any statements
                  made therein, shall not be admissible under any circumstances.


                                                                            76

                                               CONFIDENTIAL TREATMENT REQUESTED

                  Affidavits prepared for purposes of the ADR hearing also shall
                  not be admissible. As to all other matters, the neutral shall
                  have sole discretion regarding the admissibility of any
                  evidence.

                  6. Within seven (7) days following completion of the hearing,
                  each Party may submit to the other Party and the neutral a
                  post-hearing brief in support of its proposed rulings and
                  remedies, provided that such brief shall not contain or
                  discuss any new evidence and shall not exceed ten (10) pages.
                  This page limitation shall apply regardless of the number of
                  issues raised in the ADR proceeding.

                  7. The neutral shall rule on each disputed issue within
                  fourteen (14) days following completion of the hearing. Such
                  ruling shall adopt in its entirety the proposed ruling and
                  remedy of one of the parties on each disputed issue but may
                  adopt one Party's proposed rulings and remedies on some issues
                  and the other Party's proposed rulings and remedies on other
                  issues. The neutral shall not issue any written opinion or
                  otherwise explain the basis of the ruling.

                  8. The neutral shall be paid a reasonable fee plus expenses.
                  These fees and expenses, along with the reasonable legal fees
                  and expenses of the prevailing Party (including all expert
                  witness fees and expenses), the fees and expenses of a court
                  reporter, and any expenses for a hearing room, shall be paid
                  as follows:

                           (a) If the neutral rules in favor of one Party on all
                  disputed issues in the ADR, the losing Party shall pay 100% of
                  such fees and expenses.

                           (b) If the neutral rules in favor of one Party on
                  some issues and the other Party on other issues, the neutral
                  shall issue with the rulings a written determination as to how
                  such fees and expenses shall be allocated between the parties.
                  The neutral shall allocate fees and expenses in a way that
                  bears a reasonable relationship to the outcome of the ADR,
                  with the Party prevailing on more issues, or on issues of
                  greater value or gravity, recovering a relatively larger share
                  of its legal fees and expenses.

                  9. The rulings of the neutral and the allocation of fees and
                  expenses shall be binding, non-reviewable, and non-appealable,
                  and may be entered as a final judgment in any court having
                  jurisdiction.


                                                                            77

                  10. Except as provided in paragraph 9 or as required by law,
                  the existence of the dispute, any settlement negotiations, the
                  ADR hearing, any submissions (including exhibits, testimony,
                  proposed rulings, and briefs), and the rulings shall be deemed
                  Confidential Information. The neutral shall have the authority
                  to impose sanctions for unauthorized disclosure of
                  Confidential Information.


                                                                            78

                               JOINT PRESS RELEASE

ABBOTT AND SUPERGEN SIGN WORLDWIDE SALES AND DISTRIBUTION AGREEMENT FOR
CHEMOTHERAPY COMPOUND RUBITECAN

Abbott Park, Ill. And San Ramon, Calif., December xx, 1999 - Abbott Laboratories
(NYSE: ABT) and SuperGen, Inc. (NASDAQ: SUPG & SUPGW & SUPGZ) today announced
the signing of a worldwide sales and marketing agreement for rubitecan.

Rubitecan is an oral chemotherapy compound in the camptothecin class and is
currently in Phase III studies for the treatment of pancreatic cancer.
Pancreatic cancer is associated with high patient mortality with over 75,000
deaths annually in the United States and Europe. It is the fourth leading cause
of death by cancer in the U.S. with an average survival rate of four to five
months following diagnosis at an advanced stage.

"Clinical data suggest that rubitecan has the potential to become a safe and
effective therapy for the treatment of pancreatic cancer, a disease for which
there are limited treatment options available," said Robert L. Parkinson,
president and chief operating officer, Abbott Laboratories. "Furthermore,
feedback from patients and clinicians worldwide has indicated a great interest
and need for an oral chemotherapy alternative."

"Completing this agreement with Abbott is certainly an historic milestone in our
continuing mission to build an independent pre-eminent cancer-fighting company,"
said Joseph Rubinfeld, Ph.D., chairman and chief executive officer of SuperGen.
"As one of the world's largest health care companies, Abbott possesses the
resources to ensure significant global market penetration of rubitecan upon
regulatory approval. This agreement allows SuperGen to maintain its considerable
U.S. presence and oncology franchise."

Under terms of the agreement, Abbott will make an initial equity investment in
SuperGen. Additional equity investments, cash milestones and option exercises
are contemplated over the life of the agreement. Abbott will have exclusive
distribution and promotion rights for rubitecan outside the U.S., and
co-promotion rights with SuperGen for rubitecan within the U.S. In addition,
Abbott will become the exclusive U.S. distributor for Nipent-Registered
Trademark-, SuperGen's currently marketed product for the treatment of hairy
cell leukemia. SuperGen retains U.S. marketing rights for Nipent-Registered
Trademark-.

Rubitecan is currently being studied at over 200 clinical sites for the
treatment of pancreatic cancer. SuperGen has previously reported that it expects
to initiate clinical trials of rubitecan for additional tumor types. Under the
agreement announced today, SuperGen will be responsible for funding clinical
development of a pancreatic claim.
