covenants and agrees to vote and to execute written consents, and to cause its Affiliates to vote and execute written consents, at any meeting of the stockholders of the Company or in any action taken by the stockholders without a meeting, with respect to all Voting Securities over which the Investor or any of its Affiliates has voting power (i) in favor of the Stockholder Approval, and (ii) against any action, agreement or proposal that would result in the Stockholder Approval not being obtained acting with the intent of hindering, delaying, frustrating, impairing or making futile or less likely the Stockholder Approval.

This agreement to vote is irrevocable and coupled with an interest and will expire upon termination of this Agreement, upon the receipt of the Stockholder Approval, or the expiration of any period beyond which agreements to vote are not enforceable under applicable law, whichever comes first.
