MISCELLANEOUS

11.1Dispute Resolution. If a dispute between the Parties arises under this Agreement, either Party shall have the right to refer such dispute in writing to the respective Executive Officers, and such Executive Officers shall attempt in good faith to resolve such dispute. If the Parties are unable to resolve a given dispute pursuant to the preceding sentence within thirty (30) days after referring such dispute to the Executive Officers, either Party may have the given dispute settled in court pursuant to the remainder of this Section 11.1. Each Party irrevocably submits to the exclusive jurisdiction of the United States District Court for the Southern District of New York for the purposes of any suit, action or other proceeding arising out of this Agreement. Each Party agrees to commence any such action, suit or proceeding in the United States District Court for the Southern District of New York or if such suit, action or other proceeding may not be brought in such court for jurisdictional reasons, in the Supreme Court of the State of New York, New York County. Each Party irrevocably and unconditionally waives any objection to the laying of venue of any such action, suit or proceeding arising out of this Agreement in the United States District Court for the Southern District of New York, and hereby and thereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum. Notwithstanding anything in this Agreement to the contrary, a Party may seek a temporary restraining order or a preliminary injunction from any court of competent jurisdiction, at any time, in order to prevent immediate and irreparable injury, loss, or damage on a provisional basis, pending the resolution of any dispute hereunder, including under this Section 11.1.

11.2Governing Law. This Agreement and any dispute arising from the performance or breach hereof shall be governed by and interpreted in accordance with the laws of the State of New York, without giving effect to any choice of law rules. The provisions of the United Nations Convention on Contracts for the International Sale of Goods shall not apply to this Agreement or any subject matter hereof.

Either Party may assign this Agreement in whole or in part to any Affiliate without the consent of the other Party. Either Party may also assign this Agreement, without the consent of the other Party, to any successor or Third Party that acquires all or substantially all of the business or assets of the assigning Party to which this Agreement relates, whether by sale, transfer, merger, reorganization, operation of law or otherwise, and Novartis may assign this Agreement to any Third Party in connection with any divestiture undertaken to satisfy an applicable governmental authority or agency; provided, that in each case such assigning Party provides the other Party with written notice of such assignment and the assignee agrees in

- 38 -

writing to assume performance of all assigned obligations. The terms of this Agreement shall be binding upon and shall inure to the benefit of the successors, heirs, administrators and permitted assigns of the Parties. Any purported assignment in violation of this Section 11.3 shall be null and void.

11.4Force Majeure. No Party shall be held liable or responsible to the other Party nor be deemed to be in default under, or in breach of any provision of, this Agreement for failure or delay in fulfilling or performing any obligation (other than a payment obligation) of this Agreement when such failure or delay is due to force majeure, and without the fault or negligence of the Party so failing or delaying. For purposes of this Agreement, force majeure is defined as causes beyond the reasonable control of the Party, including acts of God; material changes in Law; war; civil commotion; destruction of production facilities or materials by fire, flood, earthquake, explosion or storm; labor disturbances; epidemic; and failure of public utilities or common carriers. In such event XOMA or Novartis, as the case may be, shall immediately notify the other Party of such inability and of the period for which such inability is expected to continue. The Party giving such notice shall thereupon be excused from such of its obligations under this Agreement as it is thereby disabled from performing for so long as it is so disabled for up to a maximum of ninety (90) days, after which time XOMA and Novartis shall promptly meet to discuss in good faith how to best proceed in a manner that maintains and abides by the Agreement. To the extent possible, each Party shall use reasonable efforts to minimize the duration of any force majeure.

11.5Notices. Any notice or request required or permitted to be given under or in connection with this Agreement shall be given in writing and personally delivered or sent by certified mail (return receipt requested), facsimile transmission (receipt verified), or overnight express courier service (signature required), prepaid, to the Party for which such notice is intended, at the address set forth for such Party below:
