The amount of the Commitment to be funded under this letter agreement simultaneous with the Closing may be reduced in an amount specified by Parent (and agreed by the Company) but only to the extent that it will be possible for Parent and Merger Sub to consummate the transactions contemplated by the Merger Agreement with Sponsor contributing less than the full amount of the Commitment.

2.     Conditions. The Commitment shall be subject to (i) the execution and delivery of the Merger Agreement by the Company, and (ii) the satisfaction or waiver at the Closing of each of the conditions to Parent’s and Merger Sub’s obligations to consummate the transactions contemplated by the Merger Agreement.
