          (i) Victory shall provide Santarus with written notice within five (5) days following (but in any event no later than concurrently with any public announcement of) any Change in Control (as defined below) of Victory, which notice shall be referred to as a Change in Control Notice. Santarus shall then have the option, within ninety (90) days following the Change in Control Notice, to terminate the Agreement upon thirty (30) days prior written notice.

Agreement, without the consent of the other party, except for such announcements which, in accordance with the advice of legal counsel to the party making such announcement, are required by law or for such announcements that contain the same disclosure as in prior permitted/approved public announcements.

16. Miscellaneous.

     16.1 Assignment. This Agreement may be assigned by either party without the consent of the other party to (i) an Affiliate, or (ii) a third party in connection with the acquisition of a party (whether by merger, asset sale or otherwise) or the business of a party associated with the Product. This Agreement may not otherwise be assigned by either party without the prior written consent of the other party, which consent shall not be unreasonably withheld or delayed. Each party shall provide the other with at least thirty (30) days prior written notice of any assignment of this Agreement. No assignment permitted by this Section 16.1 to an Affiliate shall serve to release either party from liability for the performance of its obligations hereunder. Any assignment of this Agreement not in compliance with this Section 16.1 shall be void.

     16.2 Independent Contractors. Nothing herein contained shall be construed to constitute the parties hereto as partners or as joint venturers, or either as agent for the other. No employee or representative of a party shall have any authority to bind or obligate the other party to this Agreement for any sum in any manner whatsoever, or to create or impose any contractual or other liability on the other party without said party’s authorized written approval. For all purposes, and notwithstanding any other provision of this Agreement to the contrary, Santarus’ legal relationship under this Agreement to Victory shall be that of independent contractor.

     16.3 Entire Agreement. This Agreement represents the entire agreement between the parties concerning the subject matter hereof and supersedes all prior or contemporaneous oral or written agreements of the parties. This Agreement may be modified, amended or changed only by a written instrument signed and delivered by the parties, with clear intent to modify, amend or change the provisions hereof.

     16.4 Limitation on Damages. Neither Victory nor Santarus (which for the purposes of this Section 16.4 shall include their respective Affiliates, directors, officers, employees and agents) shall have any liability to the other for any punitive damages, special, incidental, consequential or indirect damages, relating to or arising from this Agreement, even if such damages may have been foreseeable. For the avoidance of doubt, nothing in this Section 16.4 shall be interpreted to limit the indemnification obligation of either party in connection with the characterization of damages or losses claimed by a third party as being punitive, special, incidental, consequential or indirect or other like damages or losses.

     16.5 Force Majeure. Neither party shall be liable to the other party for any failure to perform as required by this Agreement if the failure to perform is due to circumstances reasonably beyond such party’s control including, without limitation, any act of God, civil disorder or commotion, act of aggression, fire, explosion, flood, drought, war, sabotage, embargo, utility failure, material shortage, labor disturbance, national health emergency, or appropriation of property. A party whose performance is affected by a force majeure event shall

take prompt action using all commercially reasonable efforts to remedy the effects of the force majeure event.

     16.6 Dispute Resolution. The parties recognize that disputes as to certain matters may from time to time arise during the Term that 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 Section 16.6 if and when a dispute arises under this Agreement. Unless otherwise specifically recited in this Agreement, any disputes between the parties under this Agreement shall be referred to the Chief Executive Officers of Victory and Santarus for attempted good faith resolution by negotiations within sixty (60) days after such referral. During such period of good faith negotiations, any applicable time periods under this Agreement shall be tolled. In the event such executives are unable to resolve such dispute within such sixty (60) day period, the parties agree that all such disputes shall be resolved through binding arbitration before the American Arbitration Association in accordance with its then applicable rules in San Diego, California. The Parties consent to venue in San Diego and the jurisdiction of the California Superior Court in and for the County of San Diego for any arbitration award granted with respect to, and the enforcement of, the above dispute resolution provisions.

     16.7 Counterparts. This Agreement may be executed in several counterparts, each of which shall be deemed to be an original.

     16.8 Governing Law. This Agreement shall be construed and governed in all aspects under and in accordance with the law of the State of California (excluding its or any other jurisdiction’s choice of law principles).

     16.9 Waiver. Except to the extent that a party may have otherwise agreed in writing, no waiver by such party of any breach by any other party of any of the other party’s obligations, agreements or covenants hereunder shall be deemed to be a waiver by such first party of any subsequent or other breach of the same or any other obligation, agreement or covenant; nor shall any forbearance by a party to seek a remedy for any breach by the other be deemed a waiver by said party of its rights or remedies with respect to such breach or of any subsequent or other breach of the same or any other obligation, agreement or covenant.

     16.10 Binding Effect. Except as provided in Section 16.1, this Agreement shall be binding upon and inure to the benefit of the parties to this Agreement and their respective successors.

     16.11 Headings. Headings as used in this Agreement are for convenience only and are not to be construed as having any substantive effect by way of limitation or otherwise. References to Articles or Sections herein are, unless otherwise indicated, references to the designated Articles or Sections of this Agreement, unless the content requires otherwise.

     16.12 Severability. If one or more of the provisions of this Agreement shall, by any court or under any provision of law, be found to be void or unenforceable, the agreement as a whole shall not be affected thereby, and the provisions in question shall be replaced by an

interpretation in conformity with law which comes closer to effecting the parties original intention.
