The report of the consultant shall be furnished in writing to CEPHALON and LAFON, but it is understood that in no event shall CEPHALON be entitled to receive any confidential information of LAFON, including any such information related to LAFON's manufacturing process.

The indemnifying party shall have the right and obligation to defend any such suit or claim. The indemnified party may participate in the defense of such suit or claim at its sole cost and expense. This provision for indemnification shall be void and there shall be no liability against a party as to any suit or claim for which settlement or compromise or an offer of settlement or compromise is made without the prior consent of the indemnifying party. 15. Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the successors and assigns of the parties hereto. This Agreement cannot be assigned by any of the parties hereto without the prior approval of the other party in writing; provided, however, that either party may, without such consent, assign this Agreement in connection with the transfer or sale of all or substantially all of its business or in the event of its merger or consolidation with another company. Any purported assignment in violation of the preceding sentence shall be void. Any permitted assignee shall assume all obligations of its assignor under this Agreement. No assignment shall relieve either party of responsibility for the performance of any accrued obligation which such party then has hereunder. Notwithstanding the foregoing, if prior to FDA approval of the initial Licensed Product, CEPHALON (i) sells 60% or more of its tangible assets, or (ii) participates in or becomes subject to a merger in which it is not the surviving entity, the transaction may proceed without the consent of LAFON but, within ninety (90) days after such event, the parties (in the case of CEPHALON, any successor to CEPHALON) shall meet to review the development and commercialization plans for the Licensed Product of the successor entity. If the successor to CEPHALON does not wish to continue aggressively the development and commercialization plans for the Licensed Products on the same schedule as CEPHALON, it shall, upon request of LAFON, sublicense its rights under this Agreement (subject to the approval of LAFON in accordance with Article II), for a sublicense fee of no more than l.5X CEPHALON's investment in the development of Licensed Products to the date of such sublicensing in addition to any amounts due to LAFON hereunder. In case CEPHALON would grant sublicenses of its rights under the License Agreement, CEPHALON agrees that it will obtain the prior agreement of such sublicensees to abide with the provisions of -8- this Supply Agreement. In this case the parties will agree within a separate Agreement on the supply of the Compound to such sublicensees on the same terms as this Agreement. 16. Governing Law This Agreement shall be governed by and construed in accordance with the laws of France. 17. Modification or waiver No modification or waiver of any of the provisions of this Agreement shall be valid unless in writing signed by the parties hereto or signed by the party against whom enforcement of such modification or waiver is sought. 18. Notices Notice hereunder shall be deemed sufficient if given by registered air mail, postage prepaid, and addressed to the party to receive such notice at the address given above, or at such other address as may hereafter be designated by notice in writing. 19. Counterparts This Agreement shall become binding when any one or more counterparts hereof, individually or taken together, shall bear the signatures of LAFON and CEPHALON. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original as against any party whose signature appears thereon, but all of which together shall constitute one and the same instrument. 20. Entire Agreement This Agreement contains all of the covenants, terms and undertakings of the parties with respect to the particular subject matter hereof and all prior agreements among the parties relating to the subject matter hereof, whether written or oral, are merged herein and shall be of no force and effect. This Agreement cannot be changed, modified or discharged except by an instrument in writing signed by both parties hereto. 21. Severability. In case an individual clause of this Agreement would be or would become legally invalid, such defect shall not affect the validity of the total Agreement or of other clauses contained therein, except if such a defect makes the contract more burdensome than contemplated for any of the parties; in such a case, they would consult in order to find an equitable solution. -9- 22. Dispute Resolution. Any difference between the parties hereto concerning the interpretation or application of this Agreement which could not be resolved amicably shall be finally settled in accordance with the Rules of Conciliation and Arbitration of the International Chamber of Commerce by three arbitrators designated in accordance with said Rules. This Agreement shall be construed, and the rights of the parties determined, in accordance with the French laws. Judgment upon the award rendered may be entered in any court having jurisdiction thereof. The place of arbitration will be Geneva. LABORATOIRE L. LAFON CEPHALON, INC. By: /s/ F.C.
