Effective as of the date Assignee’s registration statement on Form S-1 is declared effective (the “Effective Date”), Assignor hereby assigns, conveys and transfers to Assignee all of its present and future rights, title and interests in, to and under the Plan and all awards thereunder. If Assignee’s registration statement on Form S-1 is not declared effective, this Agreement shall be void ab initio.

Upon such a determination, the parties 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 hereby be consummated as originally contemplated to the fullest extent possible.

(c) This Assignment shall inure to the benefit of Assignee and its successors and assigns, and shall be binding upon Assignor and its successors and assigns.
