The Company and each of its subsidiaries has all requisite corporate power to own, lease and operate its property and to carry on its businesses, and is duly qualified to do business and is in good standing as a foreign corporation in any jurisdiction except where the failure to be so qualified and in good standing would not have a material adverse effect on the business, assets (including intangible assets), properties, liabilities (contingent or otherwise), financial condition, operations, or results of operation of the Company or its subsidiaries, taken as a whole (a "MATERIAL ADVERSE EFFECT"). 3.2 CAPITALIZATION. The authorized capital stock of the Company consists of 40,000,000 shares of Common Stock, $0.001 par value, and 2,000,000 shares of preferred stock, $0.001 par value.

Furthermore, except as set forth in this Agreement and Schedule 3.2 there are no contracts or commitments by which the Company is or may become bound to issue additional shares of the capital stock of the Company or options, securities or rights convertible into shares of capital stock of the Company. The Company is not a party to, and it has no knowledge of, any agreement restricting the voting or transfer of any shares of the capital stock of the Company other than transfer restrictions imposed to satisfy state and federal securities laws. Except as set forth in Schedule 3.2, the offer and sale of all capital stock, convertible securities, rights, warrants, or options of the Company issued prior to each Tranche Closing complied with all applicable federal and state securities laws. Each of the Company's subsidiaries is wholly-owned by the Company. 3.3 AUTHORIZATION; NO CONFLICTS; APPROVALS. 3.3.1 All corporate action on the part of the Company, its shareholders and its directors necessary for the authorization, execution, delivery and performance of the Agreement by the Company, the authorization, sale, issuance and delivery of the Shares, the authorization and -4- issuance of the Option, and the authorization, sale, issuance and delivery of the Option Shares, and the performance of all of the Company's obligations under the Agreement has been taken or will be taken prior to the First Tranche Closing Date or the Option Closing Date. The Agreement and the other documents required to be executed and delivered by the Company hereunder (collectively, the "TRANSACTION DOCUMENTS"), when executed and delivered by the Company, shall constitute valid and binding obligations of the Company, enforceable in accordance with their terms, subject to laws of general application relating to bankruptcy, insolvency and the relief of debtors and rules of law governing specific performance, injunctive relief or other equitable remedies. The Shares and Option Shares, when issued in compliance with the provisions of this Agreement, will be validly issued, fully paid and nonassessable, and free of any liens or encumbrances, other than any permissible liens or encumbrances created by or imposed upon the Shares and Option Shares by Purchaser; provided, however, that the Shares and Option Shares are subject to restrictions on transfer under state and/or federal securities laws and as set forth in this Agreement. 3.3.2 The execution and delivery by the Company of this Agreement and the other Transaction Documents do not, and the consummation of the transactions contemplated hereby and thereby will not, (i) conflict with, or result in any violation of or breach of any provision of the Certificate of Incorporation or Bylaws of the Company, (ii) result in any violation or breach of, or constitute (with or without notice or lapse of time, or both) a default under, or give rise to a right of termination, cancellation or acceleration of any obligation or loss of any benefit under any license, assignment, note, mortgage, indenture, lease, contract or other agreement or obligation to which the Company is a party or by which the Company or any of its properties or assets may be bound, (iii) conflict with or violate any judgment, order, decree, statute, law, ordinance, rule or regulation or any material permit, concession, franchise or license applicable to the Company or any of its properties or assets, except in the case of (ii) for such violations, breaches, defaults, rights of termination, cancellation or acceleration, or losses of benefits which would not be reasonably likely to have a Material Adverse Effect. 3.3.3 No consent, approval, order or authorization of, or registration, declaration or filing with, any governmental entity is required by or with respect to the Company in connection with the execution and delivery of this Agreement and the other Transaction Documents or the consummation of the transactions contemplated hereby or thereby, except that the filing of one or more notification and report forms under the HSR Act may be required with respect to the acquisition by Purchaser of the Shares and Option Shares, and except (i) such other consents, approvals, orders, authorizations, registrations, declarations and filings as may be required under applicable federal and state securities laws and the laws of any foreign country, and (ii) such other consents, authorizations, filings, approvals and registrations which, if not obtained or made, would not be reasonably likely to have a Material Adverse Effect. 3.4 FINANCIAL STATEMENTS. The Company has delivered to Purchaser copies of the Company's audited consolidated financial statements (balance sheet, statement of operations, statement of shareholders' equity, and statement of cash flows) for the year ended December 31, 1998 and its unaudited consolidated financial statements (balance sheet, statement of operations, -5- statement of shareholders' equity, and statement of cash flows) for the quarter ended September 30, 1999 (the "COMPANY FINANCIAL STATEMENTS"). The Company Financial Statements were prepared in accordance with generally accepted accounting principles ("GAAP") applied on a consistent basis throughout the periods involved (except (i) as may be otherwise indicated in such financial statements or the notes thereto or (ii) in the case of unaudited interim statements, to the extent they may not include footnotes or may be condensed or summary statements).

Purchaser further represents that Purchaser does not have any present intention of selling, offering to sell or otherwise disposing of or distributing the Shares or Option Shares or any portion thereof. Purchaser acknowledges and understands that the entire legal and beneficial interest of the Shares and Option Shares Purchaser is acquiring is being purchased for, and will be held for the account of, Purchaser or its designated affiliate only and neither in whole nor in part for any other person. Purchaser understands that the Shares and Option Shares have not been registered under the Securities Act or other securities laws in reliance on specific exemptions therefrom, which exemptions depend upon, among other things, the bona fide nature of Purchaser's investment intent as expressed herein. 4.3.2 The Shares and Option Shares were not offered to Purchaser through, and Purchaser is not aware of, any form of general solicitation or general advertising, including, without limitation, (i) any advertisement, article, notice or other communication published in any newspaper, magazine or similar media or broadcast over television or radio, and (ii) any seminar or meeting whose attendees have been invited by any general solicitation or general advertising. 4.3.3 Purchaser is an "accredited" investor as defined in Regulation D under the Securities Act, and a "qualified institutional buyer" within the meaning of Rule 144A under the Securities Act. 4.3.4 Purchaser further acknowledges and understands that the Shares and Option Shares must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available, and the transfer complies with the restrictions set forth in Section 5.5 of this Agreement.

Purchaser is further aware that Rule 144(k) permits persons who have not been affiliates of the Company for at least three months and whose shares have been beneficially owned by a person other than the Company or its affiliates for at least two years after full payment for such shares to sell such shares without regard to the current public information, manner of sale and volume limitations described above. 4.3.6 Purchaser has reviewed with its own tax advisers the federal, state, and local tax consequences of this investment and the transactions contemplated by this Agreement and has relied solely on such advisers and not on any statements or representations of the Company or any of its agents other than the representations and warranties set forth herein. Purchaser understands that it (and not the Company) shall be responsible for its own tax liability that may arise as a result of this investment or the transactions contemplated by this Agreement. 4.4 ACCESS TO INFORMATION; INVESTMENT EXPERIENCE; NO RELIANCE. 4.4.1 ACCESS TO INFORMATION. Purchaser has, prior to the date of this Agreement, been furnished with the Company's most recent SEC Filings and given an opportunity to review material contracts and documents of the Company which have been filed as exhibits to such SEC Filings.

Purchaser has also had an opportunity to ask questions of officers of the Company, which questions were answered to its satisfaction. Purchaser, in making the investment decision, has read, reviewed, and relied solely on the Company's SEC Filings and other documents furnished by the Company, including the Company's Financial Statements, pursuant to this Agreement and the Company's representations and warranties contained herein, and has made an independent investigation, or obtained any additional information which Purchaser deems necessary to verify the accuracy and completeness of the information received. Purchaser is not relying on any oral representation of the Company or any other person, nor any written representation or assurance from the Company other than those contained in the SEC Filings or incorporated herein or therein. The foregoing, however, does not limit or modify Purchaser's right to rely upon covenants, representations and warranties of the Company in Section 3 of this Agreement. Purchaser acknowledges and agrees that the Company has no responsibility for, does not ratify, and is under no responsibility whatsoever to comment upon or correct any reports, analyses or other comments made about the Company by any third parties, including, but not limited to, analysts' research reports or comments, and Purchaser has not relied upon any such third party reports in making the decision to invest. 4.4.2 RISK OF INVESTMENT; INVESTMENT EXPERIENCE; CAPABILITY TO EVALUATE.

Purchaser has relied completely on its own judgement or the advice of its own tax, investment, legal or other advisors and has not relied on the Company or any of its affiliates, officers, directors, attorneys, accountants or any affiliates of any thereof and each other person, if any, who controls any of the foregoing, within the meaning of Section 15 of the Securities Act for any tax, investment or legal advice (other than reliance on information furnished by the Company, the representations, warranties and covenants contained herein). 4.5 BROKERS OR FINDERS. No agent, broker, investment banker, financial adviser or other firm or person is or will be entitled to any broker's or finder's fee, or any other commission or similar fee, in connection with any of the transactions contemplated by this Agreement or any of the other Transaction Documents, and Purchaser agrees to indemnify and hold the Company and its subsidiaries harmless from and against any and all claims, liabilities or obligations with respect to any such fees or commissions asserted by any person on the basis of any act or statement determined to have been made to such person by Purchaser.

Except as permitted by Section 5.3, Purchaser agrees (and shall cause its professional advisers to agree) not to disclose to any person any information or data obtained by them pursuant to Section 5.1 until such information or data otherwise becomes publicly available or except pursuant to a valid subpoena, judicial process or its equivalent or as otherwise required by law. At the Company's request, Purchaser shall, and shall cause its professional advisers to, sign a confidentiality agreement, in form and substance reasonably satisfactory to Purchaser and the Company, as a condition to the receipt of confidential nonpublic information of the Company by such advisers pursuant to Section 5.1. -13- 5.3 PUBLIC ANNOUNCEMENTS.

The Company shall not, and shall cause its officers and directors not to, make or contribute to any public statement, news release or other public communication or filing disclosing personal information concerning Purchaser or any member of Purchaser without the prior written consent of Purchaser and such member unless the Company believes in good faith, after consultation with legal counsel, that such statement, release, communication or filing is required by law. 5.4 HSR ACT The Company shall be responsible for all applicable filing fees under the Hart Scott Rodino Antitrust Improvements Act of 1976 (the "HSR ACT") relating to the acquisition of Option Shares. With respect to the exercise of the Option, Purchaser agrees not to designate an Option Closing Date on any date prior to the expiration or early termination of the applicable waiting periods under the HSR Act. 5.5 RESTRICTIONS ON TRANSFER.

Each certificate representing Shares and Option Shares shall be endorsed with the following legends, and any other legends required by law: THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, THE SALE IS MADE IN -14- ACCORDANCE WITH RULE 144 UNDER THE ACT, OR THE COMPANY RECEIVES AN OPINION OF COUNSEL FOR THE HOLDER OF THESE SECURITIES REASONABLY SATISFACTORY TO THE COMPANY, STATING THAT SUCH SALE, TRANSFER, ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.

AND ABBOTT LABORATORIES, A COPY OF WHICH AGREEMENT MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF SUPERGEN, INC. AT SUPERGEN, INC.'S PRINCIPAL EXECUTIVE OFFICES. The Company need not register a transfer of legended Securities, and may also instruct its transfer agent not to register the transfer of the Securities, unless the conditions specified in each of the foregoing legends are satisfied. The first of the foregoing legends shall be removed from any security legended pursuant to this Section 5.6, and the Company shall issue a certificate without such legend to the holder of such Securities, if such Securities are registered under the Securities Act and a prospectus meeting the requirements of Section 10 of the Securities Act is available or if such holder satisfies the requirements of Rule 144(k), or the holder provides the Company with an opinion of counsel, reasonably satisfactory to the Company, to the effect that a public sale, transfer or assignment of such Securities may be made without registration. The second of the foregoing legends shall be removed from any Security legended in accordance with this Section 5.6, and the Company shall issue a certificate without such legend to the holder of such Security at such time as such Security is transferred in accordance with Section 5.5. The stop transfer instructions with respect to any legended Security shall be removed if both of the foregoing legends are removed in accordance with this Section 5.6. 5.7 SHARE ADJUSTMENTS. The following adjustments shall apply to the then-unexercised portion (if any) of the Option. 5.7.1 In the event that the Company shall (i) pay a dividend in, or make a distribution of, shares of capital stock or other securities (including, without limitation, any rights or options to subscribe to or purchase any additional shares of any class of its capital stock, any evidence of its indebtedness or assets, or any other rights or options) on its outstanding Common Stock, (ii) subdivide its outstanding shares of Common Stock into a greater number of such shares or (iii) combine its outstanding shares of Common Stock into a smaller number of such shares, the total number of shares of Common Stock purchasable pursuant to the Option shall be adjusted so that Purchaser shall be entitled to receive at the same aggregate Option Exercise Price the number of shares of capital stock and other securities (of one or more classes) which Purchaser would have owned or would have been entitled to receive immediately following the happening of any of the -15- events described above had Purchaser acquired all shares of Common Stock purchasable under the then-unexercised portion of the Option, in full, immediately prior to the record date with respect to such event. Any adjustment made pursuant to this Section 5.7.1 shall, in the case of a dividend or distribution of Common Stock or other securities of the Company, become effective as of the record date therefor and, in the case of a subdivision or combination, be made as of the effective date thereof. 5.7.2 In the event of a capital reorganization or a reclassification of the Common Stock (except as provided in Section 5.7.1 above or Section 5.7.3 below), Purchaser shall be entitled to receive, in substitution for the Common Stock to which Purchaser would have become entitled upon exercise immediately prior to such reorganization or reclassification, the shares (of any class or classes) or other securities or property of the Company (or cash) that Purchaser would have been entitled to receive at the same Option Exercise Price upon such reorganization or reclassification if Purchaser had acquired all shares of Common Stock purchasable under the Option, in full, immediately prior to the record date with respect to such event; and in any such case, appropriate provision (as determined by the Board of Directors of the Company, whose reasonable determination shall be conclusive and, upon request by Purchaser, shall be evidenced by a certified Board resolution delivered to Purchaser) shall be made for the application of this Section 5.7.2 with respect to the rights and interests thereafter of Purchaser (including but not limited to the allocation of the exercise price between or among shares of classes of capital stock or other securities), to the end that this Section 5.7.2 (including the adjustments of the number of shares of Common Stock or other securities purchasable and the exercise price thereof) shall thereafter be reflected, as nearly as reasonably practicable, in all subsequent conversions and purchases pursuant to this Agreement for any shares or securities or other property (or cash) thereafter deliverable upon the conversion or purchase thereof. 5.7.3 In the event of any consolidation or share exchange reorganization of the Company with, or merger of the Company into, another corporation (other than a consolidation, share exchange reorganization or merger which does not result in any reclassification or change of the outstanding Common Stock), or in case of any sale or conveyance to another person of the property of the Company as an entirety or substantially as an entirety, the entity formed by such consolidation, share exchange reorganization, or merger or the person which shall have acquired such property, as the case may be, shall execute and deliver to Purchaser a supplemental agreement providing that Purchaser shall have the right thereafter (until the expiration of all purchase rights under the Option) to receive, pursuant to such supplemental agreement, solely the kind and amount of shares of stock and other securities and property (or cash) receivable upon such consolidation, share exchange, reorganization, merger, sale or transfer by a holder of the number of shares of Common Stock of the Company which Purchaser might have acquired pursuant to the Option immediately prior to such consolidation, share exchange reorganization, merger, sale or transfer. Such supplemental agreement shall provide for adjustments, which shall be as nearly equivalent as may be practicable to the adjustments provided in this Section 5.7.3. -16- 5.7.4 For the purpose of this Section 5.7, the term "COMMON STOCK" shall mean (i) the class of stock designated as Common Stock in the Certificate of Incorporation, at the date of this Agreement, or (ii) any other class of stock resulting from successive changes or reclassifications of such Common Stock. In the event that at any time as a result of an adjustment made pursuant to this Section 5.7, Purchaser shall become entitled to receive any shares of capital stock of the Company other than shares of Common Stock, thereafter the number of such other shares so receivable pursuant to this Agreement or any of the other documents required to be executed and delivered by the Company hereunder shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Common Stock contained in this Section 5.7, and all other provisions of this Agreement and the other Transaction Documents with respect to the Common Stock shall apply on like terms to any such other shares. 5.7.5 Whenever the number of shares of Common Stock purchasable pursuant to the Option is adjusted as provided in this Section 5.7, the Option Exercise Price for each share of Common Stock payable upon such exercise shall be adjusted by multiplying such exercise price immediately prior to such adjustment by a fraction, the numerator of which shall be the number of shares of Common Stock purchasable pursuant to the then-unexercised portion of the Option immediately prior to such adjustment, and the denominator of which shall be the number of shares of Common Stock so purchasable immediately thereafter. 5.7.6 The provisions of this Section 5.7 shall apply similarly to successive stock dividends, subdivisions and combinations; successive reorganizations or recapitalizations; and successive consolidations, share exchange reorganizations, mergers, sales and transfers. 5.8 FURTHER ASSURANCES At any time or from time to time after each Tranche Closing and each Option Closing, each party shall execute and deliver to the other party or parties such other documents and instruments, provide such materials and information and take such other actions as either party may reasonably request more effectively to carry out the provisions of this Agreement and the other Transaction Documents. 5.9 USE OF FUNDS The Company shall use the proceeds from the sale of the Shares to Purchaser and the milestone payments contemplated by Section 5.1 of the Worldwide Agreement for proper corporate purposes, including allocating in a responsible manner a sufficient portion of such proceeds and milestone payments calculated to cause the Company to use its reasonable efforts to fulfill its obligations under the Worldwide Agreement. 5.10 REGISTRATION RIGHTS AGREEMENT -17- If requested in writing by Purchaser, the Company agrees to enter into a registration rights agreement, in the form attached hereto as Exhibit 5.10, prior to Purchaser's sale of any of the Shares acquired hereunder.

     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.

     relating to the potential merger with or acquisition of SuperGen or of
     a controlling portion of the voting

                                                                            11

     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.

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

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.

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

     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

     Representative shall be substantially the same for both sales forces;
     (ii) the level of Discretionary Funds per Sales Representative shall be

                                                                            19

     The Parties shall conduct Product training for their respective Sales
     Representatives jointly, at such times and in such manner as set forth

     employment matters related to its Sales Representatives.

     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.

         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

                        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
          and Canada beyond those which are SuperGen's responsibility pursuant
          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


                                               CONFIDENTAIL TREATMENT REQUESTED


           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
           and approval by SuperGen's Executive Vice President of Commercial
           Operations and Abbott's Hospital Products Division Vice President of
           Commercial Operations, according to the following time-table:

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 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 CONFIDENTIAL TREATMENT REQUESTED 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 taxation agreement or treaty, or if an applicable double taxation agreement or 31 CONFIDENTIAL TREATMENT REQUESTED 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 category. In the event a cost or expense might arguably fall into more than one category, the Parties shall mutually determine which category such cost or expense most appropriately falls into. 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 CONFIDENTIAL TREATMENT REQUESTED 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.

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.

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.

(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.

After expiration or termination of this Agreement (on a Territory-by-Territory basis or as a whole) the placement of any order for Product by Abbott to SuperGen, and the acceptance of any order from, or sale of any Product to Abbott by SuperGen, shall not be construed as a renewal or extension of this Agreement nor as a waiver or reversal of termination of this Agreement. 16.11 SURVIVAL. Other than obligations which have accrued and are outstanding as of the date of any expiration or termination of this Agreement (on a Territory-by-Territory basis or as a whole), all rights granted and obligations undertaken by the Parties hereunder shall terminate immediately upon the termination or expiration of this Agreement, subject to Article 16.2 above and except for the following which shall survive according to their terms: (a) The limitations on liability of Article 12; (b) The confidentiality and nondisclosure obligations of Article 13; (c) The indemnification obligations of Article 15 with respect to events occurring prior to termination or expiration of the Agreement; (d) The insurance obligations of Article 18; and (e) The provisions of Sections 4.2(f) (as well as Section 4.3 as its relates to Section 4.2(f) with respect to the International Territory), 7.5, 7.8, 16.4 through 16.8, 20.12, 20.3 and Section 20.11. 16.12 NONEXCLUSIVE RIGHTS AND REMEDIES.

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 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. 3. No earlier than twenty-eight (28) days or later than 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 shall submit the following to the other Party and the neutral: (a) a copy of all exhibits on which such Party intends to rely in any oral or written presentation to the neutral; (b) a list of any witnesses such Party intends to 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 CONFIDENTIAL TREATMENT REQUESTED 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.

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. 79 CONFIDENTIAL TREATMENT REQUESTED Abbott Laboratories is a global, diversified health care company devoted to the discovery, development, manufacture and marketing of pharmaceutical, diagnostic, nutritional and hospital products.
