Adoption of the Merger Agreement required the affirmative vote of the holders of at least a majority of the shares of the Company’s common stock outstanding at the close of business on September 4, 2012, in accordance with Delaware law (“Proposal 1”).

Stockholders were also asked to vote on a non-binding, advisory proposal to approve certain compensation arrangements with, and items of compensation payable to, the Company’s named executive officers in connection with the merger contemplated by the Merger Agreement (“Proposal 2”).

The following are the voting results for Proposal 1 and Proposal 2:
