Until such time as Del Mar completes a Financing Transaction or the Reacquisition Option Period expires (the “Patent Prosecution Consultation Period”), Del Mar shall keep Valent informed on an ongoing basis regarding filing, prosecution and maintenance of the Assigned Patents and any actions which require to be taken in relation thereto.

MISCELLANEOUS PROVISIONS

11.1	Assignment

This Agreement may not be assigned or otherwise transferred by either Party without the prior written consent of the other Party; provided, however, that (i) either Party may assign this Agreement and any of its rights and obligations, without the consent of the other Party, to any of its Affiliates as part of an internal restructuring or reorganization; and (ii) either Party may assign this Agreement and any of its rights and obligations, without the consent of the other Party, in connection with the transfer or sale of all or substantially all of its assets or business to which this Agreement relates or in the event of its merger, consolidation, combination (including by plan of arrangement) with another Person. If Del Mar merges, consolidates or combines into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or transfers or sells all or substantially all of its assets or business to which this Agreement relates to any Person, then, and in each such case, proper provision shall be made so that the successors and assigns of Del Mar shall assume the obligations set forth in this Agreement. In particular, without limiting the aforesaid, Del Mar will not assign any of the Assigned Patents unless such assignment is specifically made subject to the terms of this Agreement. Any purported assignment in contravention of this Section 11.1 shall, at the option of the non-assigning Party, be null and void and of no effect. No assignment shall release either Party from responsibility for the performance of any accrued obligation of such Party hereunder. This Agreement shall be binding upon and enforceable against the successor to or any permitted assignees from either of the Parties hereto.

11.2

Waiver

No provision of this Agreement may be waived except in writing by the Parties hereto. No failure or delay by any Party hereto in exercising any right or remedy hereunder or under applicable law will operate as a waiver thereof, or a waiver of any right or remedy on any subsequent occasion.

Upon such determination that any term or other provision is unenforceable, invalid or illegal, the Parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner in order that the transactions contemplated by this Agreement are consummated as originally contemplated to the greatest extent possible.

In the event of any such Force Majeure, performance of the obligations will be deferred until the Force Majeure ceases. This Section will not apply to excuse a failure to make any payment when due.
