In any such litigation, Depomed may elect by notice to BLS to share equally with BLS the costs of such litigation (including any costs incurred by Depomed prior to the Effective Date) in exchange for the right to share equally with BLS in any recovery of damages resulting from such litigation. Such election by Depomed shall be made not later than 60 days from the date such litigation is commenced. BLS may not settle any such litigation in a manner that adversely affects the rights of Depomed hereunder without Depomed’s consent, which consent shall not be unreasonably withheld.

8.3 In any litigation brought by Depomed following an election by BLS pursuant to Section 8.1 not to bring suit, Depomed shall notify BLS of the commencement of that litigation and shall have the right to use and sue in BLS’s name, and BLS shall have the right, at its own expense, to be represented by counsel. In any such litigation, BLS may elect by notice to Depomed to share equally with Depomed the costs of such litigation in exchange for the right to share equally with Depomed in any recovery of damages resulting from such litigation. Such election by BLS shall be made not later than 60 days from the date of the commencement of any such action. Depomed may not settle any

BLS’s attorneys shall represent both BLS and Depomed in any such litigation, and BLS shall have sole control over any such proceedings. Depomed may retain its own lawyers at its own expense to advise Depomed with respect to the conduct of the litigation by BLS.

10. CONFIDENTIALITY

10.1 Each of BLS and Depomed shall maintain all Technical Information and Clinical Information, and any other information about this Agreement and the businesses or affairs of the other relating to each of the 500mg Product and the 1000mg Product, in confidence, and shall not at any time disclose any such information to persons other than their Affiliates, officers, employees, agents, consultants, advisers, and licensees and potential sub-licensees, except where permitted by this Agreement, and only to the extent necessary for the purposes of this Agreement.

18. FORCE MAJEURE

18.1 In the event of any failure or delay in the performance by a Party of any provision of this Agreement due to acts beyond the reasonable control of such Party (such as, for example, fire, explosion, strike or other difficulty with workmen, shortage of transportation equipment, accident, act of God, or compliance with or other action taken to carry out the intent or purpose of any law or regulation, or an order or judgment of any court of competent jurisdiction, whether interim, temporary, interlocutory or permanent), then such Party shall have such additional time to perform as shall be reasonably necessary under the circumstances.

18.2 In the event that a Party is unable to perform any of its obligations under this Agreement by a reason described in Section 18.1 above, the obligations under this Agreement shall be suspended during such time of non-performance.

19. MISCELLANEOUS

19.1 This Agreement, the Manufacturing Transfer Agreement and the Supply Agreement define the full extent of the legally enforceable undertakings of the Parties hereto with respect to the Manufacture and Marketing of the 500mg Product and the 1000mg Product for and in the Territory as of and after the Effective Date, and with respect to the rights and obligations of the Parties relating to the subject matter hereof after the Effective Date, supersedes all previous writings and understandings. No terms or provisions of this Agreement shall be varied or modified by any prior or subsequent statement, conduct or act of either of the Parties, except that the Parties may amend this Agreement by written

CONFIDENTIAL TREATMENT REQUESTED

instruments specifically referring to and executed in the same manner as this Agreement. Nothing in this Agreement affects any rights or obligations of the Parties relating to the Manufacture or Marketing of the 500mg Product for or in the Territory prior to the Effective Date, and except as otherwise expressly provided by this Agreement, none of the rights or obligations of the Parties under the Prior Agreement, any amendments thereto or any other agreements between the Parties relating to the 500mg Product in the Territory prior to the Effective Date are affected by this Agreement, provided, however, that no such rights or obligations created or arising prior to the Effective Date shall continue in force after the Effective Date except as expressly provided in this Agreement. No promise or representation, written or oral, with respect to the subject matter hereof which is not set forth explicitly in this Agreement is intended by either Party to be legally binding. Both Parties acknowledge that in deciding to enter into this Agreement and to consummate the transactions contemplated hereby, neither has relied upon any statements or representations, written or oral, other than those explicitly set forth in this Agreement.

19.2 It is the desire and intent of the Parties that the provisions of this Agreement shall be enforced to the extent permissible under the laws and public policies applied in each jurisdiction in which enforcement is sought. Accordingly, if any particular provision of this Agreement which substantially affects the commercial basis of this Agreement shall be determined to be invalid or unenforceable, such provision shall be amended as hereinafter provided to delete therefrom or revise the portion thus determined to be invalid or unenforceable. Such amendment shall apply only with respect to the operation of such provision of this Agreement in the particular jurisdiction for which such determination is made, provided no unfairness results. In such event, the Parties agree to use reasonable efforts to agree on substitute provisions, which, while valid, will achieve as closely as possible the same economic effects or commercial basis as the invalid provisions, and this Agreement otherwise shall continue in full force and effect. If the Parties cannot agree to such revision within sixty days after such invalidity or

CONFIDENTIAL TREATMENT REQUESTED

unenforceability is established, the matter may be submitted by either Party to arbitration as provided in this Agreement to finalize such revision.

19.3 The waiver by a Party of any single default or breach or succession of defaults or breaches by the other shall not deprive either Party of any right under this Agreement arising out of any subsequent default or breach.

19.4 All matters affecting the interpretation, validity, and performance of this Agreement shall be governed by the laws of the State of New York without regard to that state’s conflict of laws rules or principles.

19.5 Nothing in this Agreement authorizes either Party to act as agent for the other Party as to any matter. The relationship between Depomed and BLS is that of independent contractors.

19.6 Any and all disputes between the Parties relating in any way to the entering into of this Agreement and/or the validity, construction, meaning, enforceability, or performance of this Agreement or any of its provisions, or the intent of the Parties in entering into this Agreement, or any of its provisions arising under this Agreement, except for any disputes relating to the provisions of Articles 8, 11, 12 and 14, shall be settled by binding arbitration. Such arbitration shall be conducted at New York, New York, in accordance with the rules then pertaining of the American Arbitration Association with a panel of three arbitrators. Each Party shall select one arbitrator and the two selected arbitrators shall select the third arbitrator. If the two selected arbitrators cannot agree on a third arbitrator then the American Arbitration Association shall select said arbitrator from the National Panel of Arbitrators. Reasonable discovery as determined by the Arbitrators shall apply to the arbitration proceeding. The law of the State of New York shall apply to the arbitration proceedings. Judgment upon the award rendered by the arbitrators may be entered in any court having jurisdiction thereof. The successful Party in such arbitration, in addition to all other relief provided, shall be entitled to an award of all its reasonable
