Any share of such Third Party Royalties that remains uncredited due to the application of such floor may be carried forward to subsequent calendar quarters.

8.5 Royalty Reports and Payment. By the tenth business day of each month, Takeda shall provide Cell Genesys with a report containing information for the Licensed Territory, to the extent reasonably available to Takeda for its internal reporting process purposes, with respect to all Net Sales of the Product for the applicable month, including the amount of gross sales of Product in the Licensed Territory, an itemized calculation of Net Sales in the Licensed Territory showing deductions, to the extent practicable, provided for in the definition of “Net Sales,” a calculation of the royalty payment due on such sales, an accounting of the number of units and prices for Product sold. Within [*] business days following the end of each calendar month, Takeda shall provide Cell Genesys with a report containing the following

43.

information for the applicable calendar month: the amount of gross sales of Product in the Licensed Territory, an itemized calculation of Net Sales in the Licensed Territory showing deductions, to the extent practicable, provided for in the definition of “Net Sales,” a calculation of the royalty payment due on such sales, an accounting of the number of units and prices for Product sold, the exchange rate for each country in which Product was sold, the application of the reductions, if any, made in accordance with the terms of Section 8.4(d) or Section 8.4(e)(iii), and any information required by Cell Genesys for the purpose of calculating royalties and other amounts due under the Upstream Agreements. Within [*] business days following its receipt of such report, Cell Genesys shall review and record such information as it determines necessary under its internal financial reporting procedures. Within [*] business days following the end of each calendar quarter, Takeda shall provide Cell Genesys with a report containing the information described above in respect of such calendar quarter for Cell Genesys’ review and confirmation within [*] business days from receipt. In the event that either party determines that the calculation of Net Sales for a calendar quarter deviates from the amounts previously reported to Cell Genesys for any reason (such as, on account of additional amounts collected or Product returns), Takeda and Cell Genesys shall reasonably cooperate to reconcile any such deviations to the extent necessary under applicable legal or financial reporting requirements. Within [*] business days following Cell Genesys’ written confirmation of the applicable quarterly report, Takeda shall pay all amounts due to Cell Genesys pursuant to Section 8.4 with respect to Net Sales by Takeda, its Affiliates and their respective sublicensees for such calendar quarter.

8.6 Foreign Exchange.

If Cell Genesys does not receive payment of any sum due to it on or before the due date, simple interest shall thereafter accrue on the sum due to Cell Genesys until the date of payment at the per annum rate of [*] over the then-current prime rate quoted by Citibank in New York City or the maximum rate allowable by applicable Law, whichever is lower.

8.8 Records; Audits. Takeda will maintain complete and accurate records in sufficient detail to permit Cell Genesys to confirm the accuracy of the calculation of royalty and other payments under this Agreement. Upon reasonable prior notice, such records shall be available during regular business hours for a period of [*] from the end of the calendar year to which they pertain for examination at the expense of Cell Genesys, and not more often than once each calendar year, by an independent certified public accountant selected by Cell Genesys and reasonably acceptable to Takeda, for the sole purpose of verifying the accuracy of the financial reports furnished by Takeda pursuant to this Agreement. Takeda acknowledges that, pursuant to certain of the Upstream Agreements, Cell Genesys is required to permit its upstream licensors to conduct similar audits of Takeda’s records. Takeda shall permit any such audit by such licensors; provided, that such audit is conducted in accordance with the terms of this Section 8.8;

44.

and provided, further, that any such audit shall not count towards the once per calendar year limit. Any such auditor shall not disclose Takeda’s Confidential Information, except to the extent such disclosure is necessary to verify the accuracy of the financial reports furnished by Takeda or the amount of payments due by Takeda under this Agreement. Any amounts shown to be owed but unpaid shall be paid within thirty (30) days from the accountant’s report, plus interest (as set forth in Section 8.7) from the original due date. Any amounts shown to have been overpaid shall be refunded within thirty (30) days from the accountant’s report.

Upon the receipt thereof, any deduction and withholding of taxes shall be made at the appropriate treaty tax rate.

(d) Assessment. Either Party may, at its own expense, protest any assessment, proposed assessment, or other claim by any Governmental Authority for any additional amount of taxes, interest or penalties or seek a refund of such amounts paid if permitted to do so by applicable Law. The Parties shall cooperate with each other in any protest by providing records and such additional information as may reasonably be necessary for a Party to pursue such protest.

Cell Genesys shall defend, indemnify, and hold Takeda and Takeda’s officers, directors, employees, and agents (the “Takeda Indemnitees”) harmless from and against any and all Third Party claims, suits, proceedings, damages, expenses (including court costs and reasonable attorneys’ fees and expenses), and recoveries (collectively, “Claims”) to the extent that such Claims arise out of, are based on, or result from (a) the Development, Manufacture, storage, handling, use, promotion, sale, offer for sale, and importation of Products by or on behalf of Cell Genesys or its Affiliates, distributors (other than Takeda), sublicensees (other than Takeda), or contract manufacturers (the “Cell Genesys Group”) (unless and to the extent such liability for Manufacturing activities are covered by separate indemnification pursuant to the Supply Agreement, which in such event will control), or (b) the breach of any representation, warranty or covenant of Cell Genesys in this Agreement, or (c) the willful misconduct or negligent acts of Cell Genesys, its Affiliates, or the officers, directors, employees, or agents of Cell Genesys or its Affiliates. The foregoing indemnity obligation shall not apply to the extent that (i) the Takeda Indemnitees fail to comply with the indemnification procedures set forth in Section 11.3 and Cell Genesys’ defense of the relevant Claims is prejudiced by such failure, or (ii) any Claim arises from, is based on, or results from any activity for which Takeda is obligated to indemnify the Cell Genesys Indemnitees under Section 11.2.

11.2 Indemnification by Takeda. Takeda shall defend, indemnify, and hold Cell Genesys and Cell Genesys’ officers, directors, employees, and agents (the “Cell Genesys Indemnitees”) harmless from and against any and all Claims to the extent that such Claims arise out of, are based on, or result from (a) the Development, storage, handling, Distribution, use, Manufacture (unless and to the extent liability for Manufacturing activities are covered by separate indemnification pursuant to the Supply Agreement, which in such event will control) promotion, sale, offer for sale, and importation of Products by Takeda or its Affiliates, or its or their sublicensees, or distributors, or (b) the breach of any representation, warranty or covenant of Takeda set forth in this Agreement, or (c) the willful misconduct or negligent acts of Takeda or its Affiliates, or the officers, directors, employees, or agents of Takeda or its Affiliates. The foregoing indemnity obligation shall not apply to the extent that (i) the Cell Genesys Indemnitees

55.

fail to comply with the indemnification procedures set forth in Section 11.3 and Takeda’s defense of the relevant Claims is prejudiced by such failure, or (ii) any Claim arises from, is based on, or results from any activity for which Cell Genesys is obligated to indemnify the Takeda Indemnitees under Section 11.1.

11.3 Indemnification Procedures. The Party claiming indemnity under this Article 11 (the “Indemnified Party”) shall give written notice to the Party from whom indemnity is being sought (the “Indemnifying Party”) in a reasonably timely manner after learning of such Claim. The Indemnified Party shall provide the Indemnifying Party with reasonable assistance, at the Indemnifying Party’s expense, in connection with the defense of the claim for which indemnity is being sought. The Indemnified Party may participate in and monitor such defense with counsel of its own choosing at its sole expense; provided, however, the Indemnifying Party shall have the right to assume and conduct the defense of the claim with counsel of its choice. The Indemnifying Party shall not settle any claim without the prior written consent of the Indemnified Party, not to be unreasonably withheld, unless the settlement involves only the payment of money. So long as the Indemnifying Party is actively defending the claim in good faith, the Indemnified Party shall not settle any such claim without the prior written consent of the Indemnifying Party. If the Indemnifying Party does not assume and conduct the defense of the claim as provided above, (a) the Indemnified Party may defend against, and consent to the entry of any judgment or enter into any settlement with respect to the claim in any manner the Indemnified Party may deem reasonably appropriate (and the Indemnified Party need not consult with, or obtain any consent from, the Indemnifying Party in connection therewith), and (b) the Indemnifying Party will remain responsible to indemnify the Indemnified Party as provided in this Article 11.

11.4 Limitation of Liability. NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY SPECIAL, CONSEQUENTIAL, INCIDENTAL, PUNITIVE, OR INDIRECT DAMAGES ARISING FROM OR RELATING TO ANY BREACH OF THIS AGREEMENT, REGARDLESS OF ANY NOTICE OF THE POSSIBILITY OF SUCH DAMAGES. NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS SECTION 11.4 IS INTENDED TO OR SHALL LIMIT OR RESTRICT THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF ANY PARTY UNDER SECTION 11.1 OR 11.2, OR DAMAGES AVAILABLE FOR A PARTY’S BREACH OF CONFIDENTIALITY OBLIGATIONS IN ARTICLE 12.

11.5 Insurance. Each Party shall procure and maintain insurance, including product liability insurance, adequate to cover its obligations hereunder and which are consistent with normal business practices of prudent companies similarly situated at all times during which any Product is being clinically tested in human subjects or commercially distributed or sold by such Party. It is understood that such insurance shall not be construed to create a limit of either Party’s liability with respect to its indemnification obligations under this Article 11. Each Party shall provide the other Party with written evidence of such insurance upon request. Each Party shall provide the other Party with written notice at least thirty (30) days prior to the cancellation, non-renewal or material change in such insurance or self-insurance which materially adversely affects the rights of the other Party hereunder.

56.

ARTICLE 12

CONFIDENTIALITY

12.1 Confidentiality. Except to the extent expressly authorized by this Agreement or otherwise agreed in writing by the Parties during a period that is the longer of (i) the Term, or (ii) [*] years from the Effective Date, each Party agrees that it shall keep confidential and shall not publish or otherwise disclose and shall not use for any purpose other than as provided for in this Agreement any Confidential Information furnished to it by the other Party pursuant to this Agreement except for that portion of such information or materials that the receiving Party can demonstrate by competent written proof:

(b) Neither Party shall issue any additional press release or other publicity materials, or make any public presentation with respect to the terms or conditions of, this Agreement or the programs or efforts being conducted by the other Party hereunder, in each case without the prior written consent of the other Party. This restriction shall not apply to any future disclosures required by law or regulation, including as may be required in connection with any filings made with, or by the requirements of the securities exchange on which such Party’s securities are traded; provided, that the disclosing Party (i) use all reasonable efforts to inform the other Party at least three (3) business days prior to making any such disclosures and cooperate with the other Party in seeking a protective order or other appropriate remedy (including redaction) and (ii) whenever possible, request confidential treatment of such information. In addition, where required by law or by the regulations of the applicable securities exchange upon which a Party may be listed, such Party shall have the right to make a press release announcing the achievement of each milestone under this Agreement as it is achieved, and the achievements of Regulatory Approvals in the Licensed Territory as they occur, subject only to the review procedure set forth in the preceding sentence. In relation to the other Party’s review of such an announcement, such other Party may make specific, reasonable comments on such proposed press release within the prescribed time for commentary, but shall not withhold its consent to disclosure of the information that the relevant milestone has been achieved and triggered a payment hereunder. Neither Party shall be required to seek the permission of the other Party to repeat any information regarding the terms of this Agreement that has already been publicly disclosed by such Party, or by the other Party, in accordance with this Section 12.3.

58.

TERM AND TERMINATION

13.1 Term. This Agreement shall become effective on the Effective Date and, unless earlier terminated pursuant to this Article 13, shall remain in effect, on a Product-by-Product basis and on a country-by-country basis, until the expiration of the Royalty Term of such Product in such country.

13.2 Early Termination.

(a) Unilateral Termination by Takeda Prior to First Commercial Sale. Prior to First Commercial Sale in the Licensed Territory, Takeda shall have the right to terminate this Agreement, for any or no reason upon [*] written notice, either (i) in its entirety, or (ii) country by country.

(b) Unilateral Termination by Takeda After First Commercial Sale. Effective only after First Commercial Sale, Takeda shall have the right to terminate this Agreement, for any or no reason, upon [*] written notice to Cell Genesys, either (i) in its entirety, or (ii) country by country; provided, that no termination under this Section 13.2(b) shall become effective prior to the second anniversary of such First Commercial Sale(s) in the relevant country(ies).

(c) Unilateral Termination by Takeda for Lack of Commercial Viability. Effective only after the First Commercial Sale, Takeda shall have the right to terminate this Agreement in its entirety or country by country upon [*] written notice to Cell Genesys, if Takeda determines in good faith that the continued Development and Commercialization of the Product under this Agreement in its entirety or country by country is and will not be commercially viable or profitable; provided, that no such termination shall become effective prior to (i) the first anniversary of the First Commercial Sale in any country in the Licensed Territory, or (ii) six months following the First Commercial Sale in any country in the Licensed Territory in the case where an applicable Law of any Governmental Authority results in a materially adverse market environment for the Commercialization of the Product which is not likely to ▇▇▇▇▇ before the first anniversary of the First Commercial Sale in any country in the Licensed Territory. The determination of profitability and commercial viability under this Section 13.2(c) shall be made on the basis of Diligent Efforts and taking into account financial projections suitable to support Commercialization of the Product on the terms set forth in this Agreement.

13.3 Termination for Breach. Cell Genesys shall have the right to terminate this Agreement upon written notice to Takeda for material breach by Takeda of its obligations under this Agreement if, after receiving written notice identifying such material breach, Takeda fails to cure such material breach within [*] from the date of such notice (or within [*] notice in the event such breach is solely based upon Takeda’s failure to pay any undisputed amounts due Cell Genesys hereunder). Takeda shall have the right to terminate this Agreement upon written notice to Cell Genesys for material breach by Cell Genesys of its obligations under this Agreement if, after receiving written notice identifying such material breach, Cell Genesys fails

59.

to cure such breach within [*] from the date of such notice (or within [*] notice in the event such breach is solely based upon Cell Genesys’ failure to pay or credit any undisputed amounts due Takeda hereunder).

13.4 Termination for Safety. Takeda shall have the right to terminate this Agreement with at least [*] written notice at any time (i) if, subject to Section 14.3(b), [*] determine in good faith and in consideration of Diligent Efforts that the risk/benefit profile of the Product is such that the Product cannot continue to be Developed or administered to patients safely (and not for commercial reasons), or (ii) upon the occurrence of serious adverse events related to the use of Product that cause Takeda to reasonably conclude that the continued use of Product by patients will result in patients being exposed to a product in which the risks outweigh the benefits. For clarity, the pursuit of discussions under Section 14.3(b) shall not eliminate Takeda’s termination right under this Section 13.4. Upon any such termination, (x) the Parties shall reasonably cooperate with each other in the wind-down and/or, if applicable, transition of all the activities from Takeda to Cell Genesys, or such Third Party designated by Cell Genesys, (y) the provisions of Section 13.5(a), (b), (d), (e), (f) and (g) shall apply, and (z) the provisions of Section 5.7(d) shall continue to apply with respect to the regulatory reporting obligations of either Party.

The following provisions shall apply if (i) Takeda terminates this Agreement in its entirety or with respect to certain countries pursuant to Section 13.2(a), (b), or (c), or (ii) Cell Genesys terminates this Agreement in its entirety under Section 13.3 due to Takeda’s material uncured breach, and following a final, non-appealable judgment pursuant to Section 14.3 of Takeda’s material breach of this Agreement (unless Takeda in writing does not dispute Cell Genesys’ determination of Takeda’s material breach).

(a) Outstanding Obligations. Takeda shall be responsible for any outstanding payment obligations of Takeda that existed or accrued prior to the effective date of termination with respect to the terminated countries.

To the extent that any such contract between Takeda and a Third Party is not assignable to Cell Genesys, then Takeda shall reasonably cooperate with Cell Genesys to arrange to continue to and provide such services from such entity or so long as may be reasonably necessary to transition such services, but in no event for more than [*] following the effective date of such termination. Takeda and Cell Genesys each shall exercise Diligent Efforts to complete any and all of such transition activities as soon as practicable.

(h) Termination of Licenses. For clarity, upon any termination of this Agreement by Takeda under Section 13.2(a), (b), or (c), or by Cell Genesys under Section 13.3, the licenses granted to Takeda under this Agreement for such terminated country(ies) shall terminate.

(i) Partial Termination. In the event of a termination by Takeda under Section 13.2(a), (b), or (c) for a particular country, such country shall be deemed excluded from the definition of Licensed Territory.

13.6 Effect of Termination for Cell Genesys. If Takeda has the right to terminate this Agreement pursuant to Section 13.3 and elects not to exercise such right, then the following shall apply (in addition to any other rights and obligations under Section 13.3 or otherwise under this Agreement with respect to such termination):

Cell Genesys shall continue to be liable to Takeda for any uncured material breach, and Takeda shall be entitled to pursue all legal and equitable remedies arising from such material breach that are available to it. Following a final, non-appealable judgment pursuant to Section 14.3 (unless Cell Genesys in writing does not dispute Takeda’s determination of Cell Genesys’ material breach), of Cell Genesys’ material breach of this Agreement, Takeda may elect, in lieu of receiving a payment of such damages from Cell Genesys, to offset Takeda’s future payment obligations to Cell Genesys under this Agreement by the amount of damages determined and awarded to Takeda pursuant to Section 14.3 (or agreed to in writing by the Parties pursuant to Section 14.5(b)).

(b) Committee Representation; Decision-Making. If Cell Genesys’ material breach of this Agreement remains uncured, then, upon the expiration of the cure period provided

62.

in Section 13.3, Takeda may also elect to require Cell Genesys to withdraw from the Committees established pursuant to Article 3, and in such event, Cell Genesys shall no longer have the right to participate in the activities of, and decision-making by, the Committees as provided in Articles 3 and 14.

13.7 Rights in Bankruptcy.

ARTICLE 14

DISPUTE RESOLUTION

14.1 Disputes. The Parties recognize that disputes as to certain matters may from time to time arise during the Term which relate to either Party’s rights and/or obligations hereunder. It is the objective of the Parties to establish procedures to facilitate the resolution of disputes arising under this Agreement in an expedient manner by mutual cooperation and without resort to litigation. To accomplish this objective, the Parties agree to follow the procedures set forth in this Article 14 to resolve any controversy or claim arising out of, relating to or in connection with any provision of this Agreement, if and when a dispute arises under this Agreement.

14.2 Referred from Committee.

(a) General. Except as provided in Section 14.3(b), with respect to disputes arising from a Committee pursuant to the terms of Article 3, either Party may, by written notice to

63.

the other Party, have such dispute referred to each Party’s Designated Executive for attempted resolution by good faith negotiations within thirty (30) days after such notice is received, or shorter if necessary to ensure patient safety or compliance with applicable Laws. If the Designated Executives are not able to resolve such dispute within such thirty (30) day period, then if such dispute does not relate to a matter described in Section 14.2(b), either Party may at any time thereafter pursue any legal, equitable or other remedy available to it in accordance with this Article 14.

(b) Specific Decision-Making Rights. Except as provided in Section 14.3(b), if the Designated Executives of the Parties are not able to resolve a dispute within the thirty (30) day period described above, and the matter is related to one of the areas listed below, then each of Cell Genesys and Takeda shall have the unilateral right to settle such matter as provided below.

(i) Cell Genesys Decisions. [*].

(a) General Matters. Except as provided in Section 14.3(b) and except in connection with the matters described in Sections 8.2, 8.10, 13.5(f) and 14.2, with respect to all other disputes arising between the Parties and not from a Committee, including, without limitation, any alleged failure to perform, or breach of, this Agreement, or any issue relating to the interpretation or application of this Agreement, if the Parties are unable to resolve such dispute within thirty (30) days after such dispute is first identified by either Party in writing to the other, the Parties shall refer such dispute to the Designated Executive for each Party for attempted resolution by good faith negotiations within thirty (30) days after such notice is received. With respect to any dispute regarding an alleged material breach of this Agreement and termination under Section 13.3, if such dispute is not resolved by such Designated Executives within such period, then either Party may submit such dispute to mediation in accordance with Section 14.5.

64.

With respect to any other dispute that is not resolved by such Designated Executives within such period, either Party may at any time thereafter pursue any legal, equitable or other remedy available to it in accordance with this Article 14 and such dispute shall be submitted to a court of competent jurisdiction in the State of New York, United States of America. Each Party hereby consents to venue and personal jurisdiction in, and agrees to service of process issued or authorized by, such court.

(b) Safety Matters. In the event that the Parties cannot agree to one opinion with respect to an individual adverse event or other matter affecting the health, safety or welfare of a patient, then, the Parties shall convene the relevant Committee to discuss and seek resolution of such matter as expeditiously as possible to ensure patient safety and compliance with applicable Laws. In connection with such discussions, the Parties may convene any joint working groups or outside consultants and/or experts in the subject matter of the disagreement to assist the Parties to reach one opinion. If such discussions do not result in one opinion between the Parties in a reasonably timely fashion, then the most conservative opinion shall prevail.

14.4 Injunctive Relief. Nothing herein may prevent either Party from seeking a preliminary injunction or temporary restraint order in order to prevent any Confidential Information from being disclosed without appropriate authorization under this Agreement.

14.5 Mediation.

(a) Binding; Certain Provisions. Any dispute, claim or controversy arising under Sections 8.2, 8.10 or 13.5(f) shall be submitted to JAMS (or other mutually agreed applicable entity) for binding mediation or similar procedure to render a binding decision (as the Parties may agree). The mediator shall confer with the Parties to design procedures to conclude the mediation, including, if necessary, rendering a binding decision, within no more than sixty (60) days after initiation. Except for an action to obtain equitable relief, as provided in Section 14.5(c), neither Party may commence a civil action with respect to the matters submitted to mediation. The outcome of the mediation or, if necessary, the decision of the mediator shall be (i) in writing, stating the reasons for such decision; (ii) based solely on the terms and conditions of this Agreement, as interpreted, if applicable, in accordance with the laws of the State of New York; and (iii) final and binding upon the Parties hereto; and (iv) enforceable in any court of competent jurisdiction.

(b) Non-binding; Material Breach. Any dispute, claim or controversy regarding any proposed termination of this Agreement for material breach under Section 13.3 may be submitted by either Party, pursuant to Section 14.3(a), to JAMS for non-binding mediation. If such matter is not resolved within forty-five (45) days after initiation of mediation, then either Party may thereafter pursue any legal, equitable or other remedy available to it in accordance with Section 14.3(a). The mediator shall confer with the Parties to design procedures to conclude the mediation within no more than forty-five (45) days after initiation. Except for an action to obtain equitable relief, as provided in Section 14.5(c), neither Party may commence a civil action with respect to the matters submitted to mediation until at least forty-five (45) days after initiation of mediation. Mediation may continue after the commencement of a civil action, if the Parties mutually agree.

65.

(c) Procedure. Either Party may commence mediation by providing to JAMS and the other Party a written request for mediation, setting forth the subject of the dispute and the relief requested. The Parties shall promptly confer in an effort to select a mediator from the JAMS panel of neutrals by mutual agreement. In the absence of such an agreement within ten (10) days of initiation of the mediation, the mediator shall be selected by JAMS. The Parties covenant that they will participate in the mediation in good faith, and that they will share equally in its costs. All offers, promises, conduct and statements, whether oral or written, made in the course of the mediation by any of the Parties, their agents, employees, experts and attorneys, and by the mediator and any JAMS employees, are confidential, privileged and inadmissible for any purpose, including impeachment, in any litigation or other proceeding involving the parties, provided that evidence that is otherwise admissible or discoverable shall not be rendered inadmissible or non-discoverable as a result of its use in the mediation. Either Party may seek equitable relief prior to the mediation to preserve the status quo pending the completion of that process. The provisions of this Section 14.5 may be enforced by any court of competent jurisdiction, and the Party seeking enforcement shall be entitled to an award of all costs, fees and expenses, including attorneys’ fees, to be paid by the Party against whom enforcement is ordered. Either Party’s failure to perform any obligation under this Agreement due to a pending good faith mediation proceeding or request to commence mediation shall not be deemed to be a material breach of this Agreement.

ARTICLE 15

MISCELLANEOUS

15.1 Entire Agreement; Amendment. This Agreement, including the Exhibits hereto, sets forth the complete, final and exclusive agreement and all the covenants, promises, agreements, warranties, representations, conditions and understandings between the Parties hereto with respect to the subject matter hereof and supersedes, as of the Effective Date, all prior and contemporaneous agreements and understandings between the Parties with respect to the subject matter hereof; provided, that the Confidential Disclosure Agreement between the Parties dated January 17, 2007 shall continue in full force and effect in accordance with its terms.

15.2 Force Majeure. Both Parties shall be excused from the performance of their obligations under this Agreement to the extent that such performance is prevented by force majeure and the nonperforming Party promptly provides notice of the prevention to the other Party.

66.

strike or lock-out, epidemic, failure or default of public utilities or common carriers, destruction of production facilities or materials by fire, earthquake, storm or like catastrophe, and failure of plant or machinery (provided that such failure could not have been prevented by the exercise of skill, diligence, and prudence that would be reasonably and ordinarily expected from a skilled and experienced person engaged in the same type of undertaking under the same or similar circumstances). Notwithstanding the foregoing, a Party shall not be excused from making payments owed hereunder because of a force majeure affecting such Party.

PRESS RELEASE

Cell Genesys and Takeda Announce Global Alliance for the Development and Commercialization of

GVAX Immunotherapy for Prostate Cancer

SOUTH SAN FRANCISCO, Calif. and OSAKA, Japan, March 31, 2008 (United States) and ▇▇▇▇▇ ▇, ▇▇▇▇ (▇▇▇▇▇)—Cell Genesys, Inc. (“Cell Genesys”, Nasdaq: CEGE) and Takeda Pharmaceutical Company Limited (“Takeda”, TSE: 4502) today announced that the companies have formed a global alliance for the development and commercialization of GVAX immunotherapy for prostate cancer, Cell Genesys’ lead product candidate currently in Phase 3 clinical development.

Under the agreement, in exchange for exclusive worldwide commercial rights to GVAX immunotherapy for prostate cancer, Takeda will pay Cell Genesys an upfront payment of $50 million and additional milestone payments totaling up to $270 million relating to regulatory approval and commercialization of GVAX immunotherapy for prostate cancer in the United States, European Union and Japan. Takeda will pay Cell Genesys tiered, double-digit royalties based on net sales of GVAX immunotherapy for prostate cancer in the United States and flat double-digit royalties based on net sales of the product in all other regions. From this point forward, Takeda will pay for all external development costs associated with the ongoing Phase 3 clinical development of GVAX immunotherapy for prostate cancer and will also pay for all additional development costs and all commercialization costs. Cell Genesys will maintain responsibility for the worldwide manufacture and supply of the product and will retain rights to co-promote GVAX immunotherapy for prostate cancer in the United States.

“We are very pleased to have entered into this agreement with Takeda for the development and commercialization of GVAX immunotherapy for prostate cancer and look forward to benefiting from Takeda’s impressive record of success as a global pharmaceutical business and clear commitment to become a leader in the field of oncology,” stated ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, M.D., chairman and chief executive officer of Cell Genesys. “In particular, we are very glad to have the opportunity to work with the company that pioneered the global development and commercialization of the world’s leading prostate cancer drug, Lupron^®, and hope to build on that success with GVAX immunotherapy for prostate cancer, a potential new treatment option for men with this disease.”

“We are excited to have added GVAX immunotherapy for prostate cancer to our growing oncology pipeline and are eager to do all that we can to ensure its commercial success in the United States and globally,” said ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇, president of Takeda. “Our extensive experience in the prostate cancer market, coupled with our global infrastructure of development and marketing makes us well-suited to work in partnership with Cell Genesys in the effort to make GVAX immunotherapy for prostate cancer a reality for patients in need.”

GVAX immunotherapy for prostate cancer is currently being evaluated in two Phase 3 clinical trials, VITAL-1 and VITAL-2, in patients with advanced prostate cancer. The U.S. Food and Drug Administration has granted Cell Genesys Fast Track status for the GVAX prostate cancer program and both trials have completed Special Protocol Assessment agreements. In 2007, the VITAL-1 trial completed enrollment with 626 patients and in January 2008, Cell Genesys announced that the Independent Data Monitoring Committee (IDMC) had completed a pre-planned interim analysis for VITAL-1 and recommended that the study continue. The IDMC provided no information to the company other than the recommendation to continue the trial. The company currently estimates that there will be sufficient events to trigger the final analysis for VITAL-1 in the second half of 2009. Patients are continuing to be enrolled in the VITAL-2 trial at approximately 100 clinical trial sites located in North America and Europe. Cell Genesys is targeting the completion of enrollment for VITAL-2 with approximately 600 patients in the first half of 2009 and expects that there will be sufficient events to trigger the pre-planned interim analysis in the same time frame.

About GVAX Immunotherapy for Prostate Cancer

Cell Genesys’ GVAX cancer immunotherapies are whole-cell products that are designed to present the immune system with a broad spectrum of tumor antigens and stimulate an immune response against the patient’s tumor. GVAX immunotherapy for prostate cancer is comprised of two prostate tumor cell lines that have been modified to secrete GM-CSF (granulocyte-macrophage colony stimulating factor), an immune stimulatory hormone that plays a key role in stimulating the body’s immune response, and then irradiated for safety. GVAX for prostate cancer is being developed as a non patient-specific, “off-the-shelf” pharmaceutical product. The company is currently manufacturing the product in its bioreactor manufacturing facility in Hayward, California, a facility that is also capable of producing the product for commercialization.
