RESEARCH AND LICENSE AGREEMENT

THIS RESEARCH AND LICENSE AGREEMENT (this "Agreement") is entered into and made on July 10, 2000 (the "Effective Date") by and among BIOCHEM PHARMA INC. ("BIOCHEM"), a corporation organized and existing under the laws of Canada and having its principal office at 275 Armand-Frappier Boulevard, Laval, Quebec, Canada H7V 4A7, and CYTOVIA, INC. ("CYTOVIA"), a corporation incorporated and existing under the laws of the State of Delaware, having its principal office at 6650 Nancy Ridge Drive, San Diego, California, 92121. BIOCHEM and CYTOVIA are hereinafter collectively referred to as "Parties" or individually as a "Party."

RECITALS

WHEREAS, CYTOVIA is the owner of certain intellectual property consisting of pending patent applications, know-how and inventions relating to Products (as defined below) (including methods of manufacturing such Products) for the treatment of human diseases;

WHEREAS, the parties wish to pursue research to design, synthesize, identify and characterize candidates from among the Products for clinical development and BIOCHEM wishes to pursue such development;

WHEREAS, CYTOVIA desires to grant, and BIOCHEM desires to acquire, an exclusive license (with the right to sublicense) to research, develop and commercially exploit CYTOVIA's intellectual property relating to the Products, including the right to make, have made, use, sell and have sold the Products.

The Parties shall each have the right, upon notifying the other, to change its members of the Steering Committee at any time during the term of this Agreement. The Parties shall hold meetings of the Steering Committee as mutually agreed by the Parties (but in no event less than four (4) quarterly meetings per year) to review the Research Program and to discuss future activities under this Agreement. The first meeting of the Steering Committee following the Effective Date shall be held in San Diego, CA. Thereafter, meetings shall alternate between Laval, Canada and San Diego, CA. Interim meetings may be held by telephone or video conference if requested by either Party in writing to the other, provided that the Parties shall meet in person at least four (4) times per year. Minutes of all meetings setting forth decisions of the Steering Committee relative to the Research Program shall be prepared by the host Party and circulated to both Parties within fifteen (15) days after each meeting, but minutes shall not become official until approved by both Parties. Any vote of the Steering Committee shall include at least one (1) representative of each of BIOCHEM and CYTOVIA. Steering Committee decisions shall be made by unanimous consent of the Parties after good faith discussions. In the event of a disagreement that cannot be resolved within thirty (30) days after the date on which the disagreement arose through such good faith discussions, the matter shall be referred to the CEOs of the Parties for good faith discussion, and in the event that the CEOs shall not have reached agreement within sixty (60) days after the date on which the disagreement arose, then the decision of BIOCHEM shall be

final. The Steering Committee shall terminate upon termination of the Research Program, with BIOCHEM being responsible for further development of the Products as provided in Article 5.

ARTICLE 5

REGULATORY ACTIVITIES, APPROVALS, and COMPLIANCE

5.1    Regulatory Activities and Approvals.

    5.1.1    BIOCHEM shall be responsible for, either itself or through its designee (and with CYTOVIA's assistance when reasonably requested by BIOCHEM), and fund, all pre-clinical and non-clinical work (other than CYTOVIA's responsibilities under the Research Program), all clinical trials and all other regulatory matters relating to the Products, including all communications with the relevant Agencies with respect to the Products in the Territory. BIOCHEM shall be responsible for the preparation, filing and prosecution of all INDs, as well as all other Agency filings for obtaining and maintaining Regulatory Approvals in the Territory. BIOCHEM shall own all such filings and Regulatory Approvals during and after the term of this Agreement. CYTOVIA shall provide reasonable assistance to BIOCHEM, free of charge, in preparing, filing, prosecuting, obtaining and maintaining Regulatory Approvals in the Territory, as requested by BIOCHEM. CYTOVIA shall provide BIOCHEM (or BIOCHEM's designee), free of charge, for purposes of preparing the Agency filings for the Products, the required data, properly formatted, for that portion of the Agency filings for the Products which relates to any work by CYTOVIA and all other data owned or controlled by CYTOVIA which is reasonably necessary for obtaining and maintaining Regulatory Approvals in the Territory (including any required adverse event information that may be in CYTOVIA's possession or control). Without in any way limiting the foregoing, CYTOVIA shall provide to BIOCHEM, free of charge, all Technical Information in CYTOVIA's possession or control that BIOCHEM may require to file IND's for the Products and for any subsequent modification or amendment thereto. BIOCHEM shall reimburse CYTOVIA for reasonable out of pocket expenses incurred by CYTOVIA in connection with the assistance requested by and provided to BIOCHEM under this Section 5.1.1.

5.1.2    Subject to BIOCHEM's right of termination as provided in Article 13, BIOCHEM shall use commercially reasonable efforts to:

(a) develop, or have developed, at least one (1) Product under this Agreement for an oncology indication in at least one (1) Major Country;

(b) with respect to any Product for which Regulatory Approval is obtained in any Major Country, obtain, or have obtained, Regulatory Approvals of such Product in the other Major Countries; and

(c) following Regulatory Approval in any Major Country, market and sell, or have marketed and sold, at least one (1) Product in such Major Country.

    BIOCHEM shall be deemed to be using commercially reasonable efforts with respect to the provisions of this Section 5.1.2 if BIOCHEM is actively undertaking diligent, commercially reasonable efforts, similar to those used for other BIOCHEM products of comparable commercial potential, for the continuing development and the commercialization of a Product in the Field. Without limiting BIOCHEM's obligations pursuant to parts (a), (b), and (c) of this Section, BIOCHEM shall be responsible for and retain control of all decisions regarding commercialization of the Products including development of Product, where and when to seek Regulatory Approval and where and when to market the Product(s), (including without limitation the sole discretion to decide in which Major Country to commercially exploit the Product.) In any event, BIOCHEM shall have the right to take into consideration commercial and business factors when making any determination concerning whether to file for Regulatory Approval or to Launch any Product in a country of the Territory, how to market any Product in a country of the Territory and whether to continue to market any Product in a country of the Territory, and in making such determinations shall act in accordance with its reasonable business practices and judgment in such regard. For example, it would be commercially reasonable,

notwithstanding the language of Section 5.1.2(b), not to file for Regulatory Approval in Japan where a Product is suited to Western markets but not suited to Japan.

5.1.3    In the event that CYTOVIA shall allege that BIOCHEM is failing to use commercially reasonable efforts in a Major Country as provided in Section 5.1.2 above, CYTOVIA shall notify BIOCHEM in writing. BIOCHEM shall thereafter have a period of six (6) months in which to remedy the deficiency claimed by CYTOVIA or if such deficiency cannot be remedied within six (6) months, to commence and continue good faith efforts to remedy such deficiency and remedy such deficiency within a reasonable period thereafter. If following such period, CYTOVIA claims that such deficiency has not been remedied, then CYTOVIA may submit such matter to arbitration pursuant to Section 15.5 for a determination of whether BIOCHEM is using commercially reasonable efforts provided herein. In the event that the arbitrators determine that BIOCHEM is not using such commercially reasonable efforts in a Major Country, then the arbitrators shall require each party to submit a development and/or marketing plan to remedy such deficiency in such Major Country and the arbitrators shall choose which of the two (2) plans is most reasonable and BIOCHEM shall implement such plan. This Section  5.1.3 shall not apply in the event that a discontinued Product has been returned to CYTOVIA pursuant to Section 6.11.

ARTICLE 6

LICENSE PAYMENTS, CLINICAL TRIAL AND
REGULATORY APPROVAL MILESTONES; ROYALTIES AND REPORTS

6.1    License Payments. BIOCHEM shall make the following payments to CYTOVIA in consideration of the exclusive license granted under this Agreement:

(a)    Upon the execution of this Agreement, BIOCHEM shall make a payment of [***] to CYTOVIA; and

(b)    In addition, BIOCHEM shall make four (4) payments to CYTOVIA of [***], the first upon the execution of the Agreement and the subsequent three (3) payments by the end of the three (3) calendar quarters after the calendar quarter in which the Effective Date shall occur, as well as four (4) further payments of [***] for the subsequent four (4) calendar quarters, for a total of [***].

6.2    Clinical Trial, Regulatory Approval and Commercialization Milestone Payments. BIOCHEM shall make payments to CYTOVIA in U.S. dollars as set forth within the table below within thirty (30) days after the achievement of each of the respective clinical trial, regulatory approval, and commercialization milestones, provided that, (i) only two (2) sets of milestones shall ever be payable notwithstanding the total number of Products developed or indications pursued or approved (which sets of milestones depend on the order in which Products shall be developed and approved and could be for either (a) a first and a second oncology Product, (b) a first oncology Product and a non-oncology indication for the same Product, or (c) a first oncology Product and a second non-oncology Product); (ii) in the event that a Product shall be discontinued after any milestone shall have been paid, such milestone shall be credited against the milestone due for any Product subsequently pursued; and (iii) each milestone under each of the columns, labeled (A), (B) and (C), in the table below shall be due once only. In the event that a subsequent milestone shall be triggered where a prior milestone has not been triggered (for example, Phase III trials shall be initiated without prior initiation of Phase II trials), then both milestones shall be payable upon the happening of the subsequent milestone.

Confidential Treatment Requested

Milestone	(A) First Product for Oncology related Indication	(B) Non-Oncology Indication for Product already approved or being developed for an Oncology related Indication	(C) Second Oncology Product for new Non-Oncology Product
(1) CD Designation	$[***] million	Not Applicable	Not Applicable
(2) First dosing of the first human subject	$[***] million	Not Applicable	Not Applicable

(6) First commercial sale of a Product in any Major Country	$[***] million	$[***] million	$[***] million
Total	$[***] million	$[***] million	$[***] million

With respect to milestones (5) and (6) above only, in the event that the Product shall not be covered by a Valid Patent Claim in one or more selected Major Countries as provided in Exhibit D ("Selected Major Countries") at the time that such milestone(s) shall be triggered, or if such a Valid Patent Claim is predicated only upon a pending patent application which does not mature into an issued patent within five (5) years of filing (or five (5) years of first publication in those countries where the relevant governmental agency publishes such applications), then the milestone(s) shall be reduced, or refunded to BIOCHEM (or in lieu of such refund, BIOCHEM may set off such amounts against any payments owed by BIOCHEM to CYTOVIA) as provided in Exhibit D. In the event that a Valid Patent Claim covering the Product shall subsequently issue in a Selected Major Country where the milestone had previously been paid at a reduced level, or a refund had been made by CYTOVIA, then BIOCHEM shall pay to CYTOVIA the amount of the reduction in the milestone for the country in question, or the refund, together with interest on such amount from the date when the milestone was first paid at a reduced level or the date of the refund, at the prime or other equivalent rate of Citibank for the last day of each calendar quarter, or the highest interest rate under applicable law, whichever is lower, until the date of payment by BIOCHEM.

6.3    Royalties. In all countries of the Territory in which CYTOVIA holds a Valid Patent Claim that would, but for the licenses granted by CYTOVIA hereunder, be infringed by the manufacture, use or sale of the Product as commercialized by BIOCHEM (so long as any claim covering manufacture excludes others from selling the Product as commercialized by BIOCHEM in the country in question), BIOCHEM shall pay to CYTOVIA (subject to the remaining terms and conditions of this Section 6.3) following Launch a royalty of [***] percent ([***]%) of Net Sales of the Product for so long as such a Valid Patent Claim shall exist in such country. In all other countries, BIOCHEM shall pay to CYTOVIA a royalty of [***] percent ([***]%) of Net Sales of the Product, for a maximum of [***] years following Launch. In addition, such [***] percent ([***]%) royalty shall also apply with respect to a Product for the remainder of such [***] year period in any country where such a Valid Patent Claim covering manufacture, use or sale of such Product as commercialized by BIOCHEM has expired prior to such [***] year period.

Confidential Treatment Requested

6.3.1    However, if the Valid Patent Claim arises from a pending patent application then payments at the [***] percent ([***]%) royalty level shall only be required for a period of [***] years from first publication, or, in those countries where governmental agencies do not publish patent applications, for a period of [***] years from filing. In the event that the said patent application does not mature into an issued patent within this [***] year period of time, such a patent claim will no longer be deemed a Valid Patent Claim and CYTOVIA shall refund (or in lieu of such refund, BIOCHEM may set off such amount against any payments owed by BIOCHEM to CYTOVIA) one half of any corresponding payments made at the [***] percent ([***]%) royalty rate so as to yield the rate of [***] ([***]%) of Net Sales of Product set forth above for countries where CYTOVIA does not possess a Valid Patent Claim. In the event that CYTOVIA opts for a set off rather than an immediate refund of amounts owed to BIOCHEM, the amount owed shall accrue interest from the date due, and thus the set off shall also include such interest to be computed for such unpaid amount on the last day of each calendar quarter (accruing quarterly) at the prime or other equivalent rate of Citibank for the last day of the calendar quarter, or the highest interest rate permissible under applicable law, whichever is lower. In the event that a Valid Patent Claim covering the Product as commercialized by BIOCHEM shall issue in a country where royalty was paid at the [***] percent ([***]%) level as a result of pendency of a patent application for more than the [***] year as provided herein, then BIOCHEM shall pay to CYTOVIA (taking into account any refunds made by CYTOVIA) the difference between the royalty payable at the [***] percent ([***]%) level and that paid at the [***] percent ([***]%) level for the period of the reduced royalty payments until issue of the Patent, together with interest on such amount at the prime or other equivalent rate of Citibank on the last day of each calendar quarter, or the highest interest rate permissible under applicable law, whichever is lower, until payment of such amount by BIOCHEM.

6.4    Sublicenses. In the event that BIOCHEM or any of its Affiliates sublicenses to a Third Party its rights under the licenses granted by CYTOVIA, BIOCHEM shall pay CYTOVIA (i) [***] percent ([***]%) of the Sublicensing Fees, and (ii) [***] percent ([***]%) of the royalties received from such Sublicensee based on sales of Product by such Sublicensee, in each case after deducting any royalties or other payments due to Third Parties under bona fide licensing arrangements that are reasonably necessary for the manufacture, use or sale of Products; provided, however, that in no event shall the amounts payable to CYTOVIA under this Section 6.5 be less than an amount equal to [***] percent ([***]%) or greater than [***] percent ([***]%) of the net sales of Products by such Sublicensee (where "net sales" shall be calculated in the same manner as Net Sales under this Agreement).

6.5    Payments and Royalty Report. Payments due to CYTOVIA pursuant to Sections 6.3 and 6.4 shall be paid within forty five (45) days following the end of each calendar quarter in which BIOCHEM or any of its Affiliate makes Net Sales or receives payments from a sublicensee. All such payments shall be accompanied by a report which sets forth for the preceding calendar quarter the following information:

(a)    total Net Sales of Products sold in the Territory during such period;

(b)    deductions applicable to determining the Net Sales;

(c)    the exchange rate(s) used to determine amounts owing hereunder;

(d)    the amount of royalties due pursuant to Section 6.3; and

(e)    Sublicensing Fees.

    If no payments are due to CYTOVIA for any reporting period following Launch, the written report shall so state.

Confidential Treatment Requested

6.6    Currency of Payment. All payments to be made under this Agreement shall be made in U.S. dollars. Net Sales outside the United States shall be first determined in the currency in which they are earned and shall then be converted into an amount in U.S. dollars using the noon buying rate as published in the Wall Street Journal for the last day of the calendar quarter for which such payment is being determined.

6.7    BIOCHEM Accounting Obligations and CYTOVIA Audit Rights. BIOCHEM shall keep accurate records for a period of at least five (5) years (or such longer period as may correspond to BIOCHEM's internal records retention policy) for each reporting period during the term of this Agreement and in which sales of Products occur showing sales of Products in sufficient detail to enable the reports provided under Section 6.5 to be verified. CYTOVIA shall have the right, for a period of three (3) years after receiving any report or statement with respect to Net Sales to appoint an independent certified public accountant to inspect the relevant records of BIOCHEM to verify such report or statement. BIOCHEM shall make its records available for inspection by such independent certified public accountant during regular business hours at such place or places where such records are customarily kept, upon reasonable notice, solely to verify the accuracy of the reports and payments. Such inspection right shall not be exercised more than once in any calendar year. Any examination by an independent accounting firm under this Section is to be made at the expense of CYTOVIA, except that if the results of the audit reveal that BIOCHEM has underpaid CYTOVIA by ten percent (10%) or more in any calendar year, then the audit fees shall be paid by BIOCHEM. Any such discrepancies shall be promptly corrected by payment by BIOCHEM to CYTOVIA. The accounting firm shall execute a confidentiality agreement reasonably acceptable to BIOCHEM prior to any such audit limiting the information to be provided to CYTOVIA to the numerical summary of royalties due and paid and prohibiting any disclosure to Third Parties.

6.8    Late Payments. In the event that any payment, including, without limitation, royalty and milestone payments and payments with respect to Sublicensing Fees, due hereunder is not made when due, the payment shall accrue interest from the date due, which interest shall be computed for such unpaid amounts on the last day of each calendar quarter (accruing quarterly) at the prime or other equivalent rate of Citibank for the last day of the calendar quarter plus two percent (2%), or the highest interest rate permissible under applicable law, whichever is lower. The payment of such interest shall not limit CYTOVIA from exercising any other rights it may have as a consequence of the lateness of any payment.

6.9    Exchange Control. If at any time legal restrictions prevent the prompt remittance of part or all of royalties owed by BIOCHEM to CYTOVIA hereunder with respect to any country in the world where the Product is sold, payment shall be made through any lawful means or methods that may be available as BIOCHEM shall reasonably determine.

6.10    Withholding Taxes. BIOCHEM or its Affiliates shall be entitled to deduct from its payments to CYTOVIA the amount of any withholding taxes required to be withheld by BIOCHEM or its Affiliates to the extent BIOCHEM or its Affiliates pay to the appropriate governmental authority on behalf of CYTOVIA such taxes. BIOCHEM shall deliver to CYTOVIA, upon CYTOVIA's request, proof of payment of all such taxes and the appropriate documentation which is necessary to obtain a tax credit, to the extent such tax credit can be obtained. Each Party shall provide assistance to the other Party in seeking any benefits available to such Party with respect to government tax withholdings by any relevant law or double tax treaty.

6.11    Discontinued Product. In the event that BIOCHEM shall in its discretion, discontinue development of a Product that has been designated a CD by BIOCHEM, then upon request by CYTOVIA, and provided that such discontinued Product is not similar to or otherwise competitive with a Product still under development by BIOCHEM, the Parties shall negotiate in good faith terms for the return of rights in such Product to CYTOVIA, which shall include (i) provision to CYTOVIA of data relating to such Product developed by BIOCHEM; (ii) payment by CYTOVIA to BIOCHEM of an upfront amount equal to fifty percent (50%) of all milestone payments made prior to discontinuation of the Product in question; and (iii) payment by CYTOVIA to BIOCHEM of a royalty on Net Sales of

the discontinued Product equal to [***] percent [***] in the event that the Product is discontinued after the start of Phase I Clinical Trials but before the start of Phase II Clinical Trials, [***] percent [***] if the Product is discontinued after the start of Phase II Clinical Trials but prior to the start of Phase III Clinical Trials and [***] percent [***] if the Product is discontinued after the start of Phase III Clinical Trials. The terms of such an agreement between BIOCHEM and CYTOVIA shall be based on the applicable provisions of this Agreement to the extent applicable. No further milestone or royalty payments shall be due under such agreement with respect to a discontinued Product returned to CYTOVIA, notwithstanding BIOCHEM's intellectual property rights with respect to such Product.

This confidentiality obligation shall not (a) apply to such information which is or becomes a matter of public knowledge; (b) is already in the possession of the receiving Party; (c) is disclosed non-confidentially to the receiving Party by a Third Party having the right to do so; (d) is subsequently and independently developed by employees of the receiving Party or Affiliates thereof

who had no knowledge of the Confidential Information disclosed. The Parties shall take reasonable measures to assure that no unauthorized use or disclosure is made by others to whom access to such information is granted.

9.1.2    CYTOVIA and BIOCHEM agree to limit the disclosure of any Confidential Information received hereunder to such of its employees and consultants and its Affiliates and with respect to BIOCHEM, BIOCHEM's and its Affiliates' sublicensees, distributors and partners (and to their potential sublicensees, distributors and partners) as are necessary to carry out the provisions of this Agreement and who are likewise bound by written obligations of confidentiality which are comparable to, or more stringent than, the provisions of Section 9.1.

9.2    Press Releases and Public Announcements. It is understood that either party may, subject to the terms and conditions of this Section, issue a press release announcing the execution of this Agreement as well as subsequent press releases relating to the Agreement or activities thereunder. The Parties agree to consult with each other reasonably and in good faith with respect to the text and timing of such press releases prior to the issuance thereof. Neither Party may issue a press release relating to this Agreement or its execution without the prior written consent of the other Party, provided that a Party may not unreasonably withhold consent to such releases. Either Party may issue such press releases (after providing three weeks advance written notice as to text and timing of such release) as it determines, based on advice of counsel, are reasonably necessary to comply with laws or regulations or for appropriate market disclosure.

ARTICLE 11

OWNERSHIP AND RIGHTS; PATENT PROSECUTION AND MAINTENANCE

11.1    Invention Ownership and Rights.

    11.1.1    Inventorship shall be determined by reference to United States laws pertaining to inventorship. Subject to the last sentence of this Section 11.1.1, if an invention is made in connection with the Research Program or otherwise under this Agreement by one (1) or more employees or consultants of each Party, it shall be jointly owned and if one or more claims included in an issued Patent or pending Patent application, which is filed in a patent office in the

Territory, claim such an invention, such claims shall be jointly owned (such jointly owned patent claims, excluding Dominated Patent Rights as defined below, hereafter designated as "Joint Patent Rights"). If an invention is made in connection with the Research Program or otherwise under this Agreement solely by an employee or consultant of a Party, it shall be solely owned by such Party, and any Patent filed claiming such solely owned invention shall also be solely owned by such Party. Each inventor of any invention developed in connection with the Research Program shall assign his/her interest in such invention to his/her respective Party employer, as the case may be, and such rights shall therefore vest in the respective Party employer to whom the inventor assigns his/her rights. Notwithstanding the foregoing, in the event that one (1) or more employees or consultants of each Party shall make an invention that is a type of Product, or a method of use of a Product, or a caspase screen of a type developed by CYTOVIA, or in the event that employees or consultants of BIOCHEM shall make such an invention, in each case under the Research Program or otherwise under this Agreement, such invention shall be owned by CYTOVIA and if one or more claims included in an issued Patent or pending Patent application, which is filed in a patent office in the Territory, claim such an invention (a type of Product or method of use of a Product or a caspase screen of a type developed by CYTOVIA), such claims shall be owned by CYTOVIA ("Dominated Patent Rights") (Dominated Patent Rights invented solely by employees or consultants of BIOCHEM are referred to herein as "Dominated BIOCHEM Patent Rights").

11.1.2    BIOCHEM shall have a fully-paid, irrevocable right to use or grant any rights under or otherwise commercialize any Joint Patent Rights acquired or developed in connection with the Research Program or otherwise under this Agreement by CYTOVIA and BIOCHEM and BIOCHEM may disclose any associated Technical Information to any Third Party, all without obtaining the prior written consent of CYTOVIA and without any accounting obligations. CYTOVIA shall not commercialize any Joint Patent Rights or Dominated Patent Rights or associated Technical Information, either itself or through others, without prior written agreement with BIOCHEM on compensation to BIOCHEM for such commercialization. Notwithstanding the foregoing, in the event that such Joint Patent Rights or Dominated Patent Rights claim caspase screens, CYTOVIA shall have a fully-paid, irrevocable right to use or grant any rights under or otherwise commercialize any such Joint Patent Rights or Dominated Patent Rights acquired or developed in connection with the Research Program or otherwise under this Agreement by CYTOVIA and BIOCHEM and CYTOVIA may disclose any associated Technical Information to any Third Party, all without obtaining the prior written consent of BIOCHEM and without any accounting obligations.

11.1.3    Each Party shall use reasonable efforts to advise the other of any patentable invention relating to the Products or otherwise arising out of the Research Program. As soon as one of the Parties concludes that it wishes to file a patent application covering any such invention, it shall immediately inform the other Party thereof. For this purpose, such Party will provide the other Party with the draft application, preliminary determination of inventors and scope of claims as early as possible. CYTOVIA shall be responsible for diligently filing, prosecuting and maintaining all CYTOVIA Patent Rights in the Territory related to the Products. CYTOVIA shall consult with BIOCHEM as to where and when to file patent applications which are included in such CYTOVIA Patent Rights, as well as concerning the preparation, filing, prosecution, and maintenance of such CYTOVIA Patent Rights. BIOCHEM, in collaboration with CYTOVIA, shall diligently prosecute and maintain all Joint Patent Rights. BIOCHEM shall consult with CYTOVIA as to where and when to file patent applications which are included in the Joint Patent Rights. If either Party, prior or subsequent to filing such patent applications elects not to file or prosecute such patent applications or maintain any ensuing patents, it shall notify the other Party within a reasonable period of time prior to allowing such patents to lapse or become abandoned or unenforceable, and the other Party may prepare, file, prosecute, and maintain such patents. Costs of prosecuting and maintaining CYTOVIA Patent Rights and Joint Patent Rights shall be shared such that seventy-five percent (75%) of such cost will be borne by BIOCHEM, while CYTOVIA shall bear the remaining twenty-five percent (25%) of the cost.

11.1.4    Each Party shall provide a draft to the other Party of each application it shall intend to file pursuant to Section  11.1.3. Each Party shall also advise the other Party within ten (10) days of receiving any substantial action or development in the prosecution of such patent applications, in particular those involving into which countries to continue prosecution, the question of the scope of, the issuance of, the rejection of, an interference involving, or an opposition to any such patent application or resulting patent. CYTOVIA shall not file any application or take any other action in prosecution with respect to the CYTOVIA Patent Rights licensed hereunder without consulting with BIOCHEM, provided that in the event of a disagreement concerning a patent prosecution matter, interference or opposition, BIOCHEM's directions shall be followed by CYTOVIA. CYTOVIA shall not cancel any claim in a pending patent application within the CYTOVIA Patent Rights without notifying BIOCHEM. If BIOCHEM wishes the canceled claims to remain, it shall provide reasons to CYTOVIA why such claim should not be canceled and the parties shall discuss in good faith a resolution of such matter.

11.1.5    At the request of the Party performing the prosecution of any patent application under Section 11.1.3, the other Party shall cooperate, in all reasonable ways, in connection with the prosecution of all such patent applications. Each Party shall make available to the other or its respective authorized attorneys, agents or representatives such of its employees as the other Party in its reasonable judgment deems necessary in order to assist such other Party with the prosecution of such patents. Each Party shall sign or use its best efforts to have signed at no charge to the other Party all legal documents necessary in connection with such prosecution and maintenance.

11.1.6    The Party performing the prosecution of any patent application under Section 11.1.3 shall provide the other Party with a report no less frequently than once per year listing all such patents and patent applications, identifying them by country and patent or application number, and briefly describing the status thereof.

ARTICLE 12

INFRINGEMENT OF THIRD PARTY PATENTS; ENFORCEMENT

12.1    Enforcement of CYTOVIA Patent Rights and Joint Patent Rights.

    12.1.1    Upon learning of any infringement of CYTOVIA Patent Rights relating to any Product or any infringement of any Joint Patent Rights by a Third Party in the Territory, CYTOVIA or BIOCHEM, as the case may be, shall promptly provide notice to the other Party in writing of the fact and shall supply the other Party with all evidence possessed by the notifying Party pertaining to said infringement.

12.1.2    BIOCHEM shall have the first right, but not the obligation, to seek to abate the infringement, or to file suit against any such infringing party, at its sole expense, following consultation with CYTOVIA. CYTOVIA shall fully cooperate with BIOCHEM, at BIOCHEM's reasonable expense, in any action brought by BIOCHEM, including by being joined as a party. If BIOCHEM does not, within one hundred twenty (120) days of receipt of such notice, take steps to abate the infringement or file suit to enforce the CYTOVIA Patent Rights or Joint Patent Rights against such infringing party in a country in the Territory, CYTOVIA shall have the right (but not the obligation) to take action to enforce the CYTOVIA Patent Rights or Joint Patent Rights against such infringing party in such country.

12.1.3    The Party controlling any such action may not settle or consent to an adverse judgement without the express written consent of the non-controlling Party (such consent not to be unreasonably withheld). All monies recovered upon the final judgment or settlement of any such action, shall be used first, to reimburse each of BIOCHEM and CYTOVIA, on a pro rata basis for its out-of-pocket expenses relating to the action, second, any remaining balance that represents compensation for lost sales, a reasonable royalty or lost profits, shall be retained by or paid to BIOCHEM subject to payment of a royalty to CYTOVIA on such balance as if it were Net Sales of Products, and third, any remaining amount that represents additional damages (for example,

enhanced damages) shall be shared by the Parties on a pro-rata basis based upon the ratio of costs and expenses incurred by each Party respectively in connection with such action.

12.2    Third Party Royalties or Other Payments; Reduction in Royalties.

    12.2.1    In the event that a Third Party shall make any claim or bring any suit or other proceeding against BIOCHEM or its sublicensees or customers, for infringement or misappropriation of any intellectual property rights with respect to any Product, BIOCHEM shall have the right to defend and control the defense of such claim, suit or other proceeding as well as to initiate and control any counterclaim or other similar action. CYTOVIA shall fully cooperate with BIOCHEM, at BIOCHEM's reasonable expense, in defense of such claim, suit or other proceeding, including by being joined as a party. The provisions of Section 12.1.3 shall apply to any proceeding covered by this Section  12.2.1, except that the negotiation of any license from the Third Party shall be subject to Section 12.2.2. BIOCHEM shall have the right to credit as incurred the amount of all Loss arising out of any claim, suit or other proceeding against royalties and/or other payments payable to CYTOVIA under this Agreement.

12.2.2    If BIOCHEM in its sole, reasonable business judgment determines or the Parties mutually agree that it is necessary or desirable to seek a license or immunity from suit from any Third Party in order for BIOCHEM to exercise its rights hereunder to develop, manufacture, commercialize, use or exploit Products in any country of the Territory, CYTOVIA shall have the obligation to obtain any such license or immunity from suit and the parties shall share equally as incurred in the amount of such royalties and other payments in such country to such Third Party applicable to BIOCHEM's activities under this Agreement. BIOCHEM shall be responsible for payment of such royalties and other payments, subject to the final sentence of this Section 12.2.2. BIOCHEM shall have the right, at BIOCHEM's option, to be the licensee of any license sought pursuant to this Section 12.2.2, and CYTOVIA shall consult with BIOCHEM in connection with obtaining, and the negotiation of the terms and conditions of any such license, and shall take into account BIOCHEM's comments related thereto and incorporate or act on such comments to the extent reasonable. If BIOCHEM notifies CYTOVIA that BIOCHEM does not want to be the licensee, CYTOVIA shall be the licensee. CYTOVIA shall obtain BIOCHEM's prior written consent (which consent shall not be unreasonably withheld) before entering into any license or other agreement pursuant to this Section. If CYTOVIA does not obtain such license or immunity from suit within ninety (90) days of the earlier of (i) BIOCHEM's, or the Parties mutual, determination to seek such license or immunity from suit, or (ii) the commencement of negotiations with such Third Party, BIOCHEM shall have the right (but not the obligation) to obtain such license or immunity from suit (and shall consult with CYTOVIA in connection with obtaining and negotiating of the terms and conditions of any such license), and the Parties shall share equally in the amount of such royalties and other payments in such country to such Third Party. BIOCHEM shall credit as incurred half the amount of any such royalties and other payments against royalties and other payments payable to CYTOVIA under this Agreement, including milestones, and in the event that the amount of such credit exceeds the amounts due to CYTOVIA in any quarter, BIOCHEM shall pay the excess, but may set off such excess against royalties and other payments payable to CYTOVIA hereunder in future quarters.

Unless otherwise mutually agreed by the Parties, only if the Dispute is not resolved through face-to-face negotiations or mediation as set forth above in this Section 15.5, may a Party resort to arbitration.

15.5.2    Except as provided in this Section 15.5, all Disputes relating in any way to this Agreement shall be resolved exclusively through arbitration conducted under the auspices of the Center for Public Resources (the "CPR") pursuant to CPR's Model ADR Procedure: Non-Administered International Arbitration Rules and Commentary.

Unless otherwise mutually agreed by the Parties, any arbitration brought hereunder shall be brought only and exclusively in New York, New York.

The arbitrators shall render a formal, binding non-appealable resolution and award on each issue as expeditiously as possible, but not more than fifteen (15) business days after the hearing. In any arbitration, the prevailing Party shall be entitled to reimbursement of its reasonable attorneys' fees and the Parties shall use all reasonable efforts to keep arbitration costs to a minimum.

15.5.3    In no event shall arbitrators have the power or authority to terminate this Agreement in whole or in part.

15.5.4    Nothing in this Agreement shall be deemed as preventing either Party from seeking injunctive relief (or any other provisional remedy) from any court having jurisdiction over the Parties and the subject matter of the dispute as necessary to protect either Party's intellectual property.

15.7    Severability. In the event that any provision of this Agreement shall be held to be unenforceable, invalid or in contravention of applicable law, such provision shall be of no effect, and the Parties shall negotiate in good faith to replace such provision with a provision which effects to the extent possible the original intent of such provision.

15.10    No Agency. Neither Party shall by virtue of this Agreement have any power to bind the other to any obligation nor shall this Agreement create any relationship of agency, partnership or joint venture or any fiduciary relationship.

15.11    No Waiver. No term or condition of this Agreement shall be considered waived unless reduced to writing and duly executed by a duly authorized officer of the waiving Party. Any waiver by any Party of a breach of any term or condition of this Agreement will not be considered as a waiver of any subsequent breach of this Agreement, of that term or condition or any other term or condition hereof.

15.12    License Survival During Bankruptcy. All rights and licenses granted under or pursuant to this Agreement are, and shall otherwise be deemed to be, for purposes of Paragraph 365(n) of the U.S. Bankruptcy Code, licenses of rights to "intellectual property" as defined under Paragraph 101(35A) of the U.S. Bankruptcy Code. The Parties agree that BIOCHEM, as a licensee of such rights under this Agreement, shall retain and may fully exercise all of its rights and elections under the U.S. Bankruptcy Code.

MILESTONE REDUCTION

    Solely with respect to the milestones numbered (5) and (6) in Section 6.2, in the event that the manufacture, use or sale of the Product as developed by BIOCHEM shall not be covered by a Valid Patent Claim in one or more Selected Major Countries as provided below at the time that such milestone(s) shall be triggered (with any such Valid Patent Claim covering manufacture excluding others from selling the Product as developed by BIOCHEM), then the amount of the applicable milestone payment owed to CYTOVIA shall re reduced by the sum of the applicable percentage(s) in the following table:

Selected Major Country in which no Valid Patent Claim covers manufacture, use or sale of Product:		Percentage by which applicable milestone shall be reduced
United States		[***]
France		[***]
Germany		[***]
United Kingdom		[***]
	Maximum Aggregate Milestone Reduction	[***]

    Notwithstanding any provisions to the contrary, milestone payments shall be due only at the reduced level (as indicated in the table above) if a pending patent application containing such a Valid Patent Claim covering the manufacture, use or sale of the Product as developed by BIOCHEM does not mature into an issued patent within five (5) years of first publication of such patent application by the relevant governmental agency, or, in those countries which do not publish applications, within five (5) years of filing such application. Any payments made by BIOCHEM to CYTOVIA upon triggering of milestones for Product as developed by BIOCHEM covered by a Valid Patent Claim during the pendency of a patent application shall be refunded (or in lieu of such refund, BIOCHEM may, subject to the terms discussed below, set off such amount against any payments owed by BIOCHEM or CYTOVIA) by CYTOVIA so as to bring the net amount of payments made by CYTOVIA down to the reduced level (in the same manner as indicated for milestones triggered in the absence of a Valid Patent Claim) set forth in the table above in the event of failure of such patent claim to issue during such time period. In lieu of such refund, either CYTOVIA or BIOCHEM may opt to deduct amounts so owed by CYTOVIA from other payments, including royalty or milestone payments, owed by BIOCHEM to CYTOVIA, provided that the amount owed shall accrue interest from the date due, and thus the set off shall also include such interest. The interest on amounts owed by CYTOVIA and the resultant amount to be setoff pursuant to this Section shall be computed for such unpaid amount

Exhibit D-1

on the last day of each calendar quarter (accruing quarterly) at the prime or other equivalent rate of Citibank for the last day of the calendar quarter, or the highest interest rate permissible under applicable law, whichever is lower.

    For purposes of clarification, BIOCHEM shall be entitled to milestone reduction(s) in Selected Major Country(ies) in which, at the time of occurrence of the applicable milestone no Valid Patent Claim covers the manufacture, use or sale of the applicable Product as developed by BIOCHEM (with any such Valid Patent Claim covering manufacture excluding others from selling the Product as developed by BIOCHEM) or where a milestone is paid, but no patent issues within the five (5) year period discussed in the previous paragraph. For example, if upon the first NDA filing for a Product as developed by BIOCHEM in any Major Country, the manufacture, use or sale of such Product is covered by at least one such Valid Patent Claim in France and the United Kingdom but by no Valid Patent Claim in Germany or the United States, then the milestone payment due to CYTOVIA shall be reduced by [***]% (which represents the sum of the United States milestone reduction ([***]%) and the Germany milestone reduction ([***]%). In no event shall any milestone payment be reduced by more than [***]% in the aggregate. If a Valid Patent Claim covering the manufacture, use or sale of the Product as developed by BIOCHEM subsequently issues in the United States (with any such Valid Patent Claim covering manufacture excluding others from selling the Product as developed by BIOCHEM), BIOCHEM would pay the amount of [***]% of the milestone as provided herein. If a Valid Patent Claim covering the manufacture, use of sale of the Product no longer existed in the United Kingdom as a result of the expiration of the five (5) year period, the amount of [***]% would be refunded or set off as provided herein.
