The Merger – Background of the Merger

The following disclosure supplements the discussion beginning on page 24 of the Definitive Proxy Statement under the heading “Background of the Merger”:

On February 17, 2011, the board of directors held a meeting, at which representatives of Gibson Dunn, the Company’s legal advisor, were present. Among other things, the board of directors reviewed the Delaware Court of Chancery’s decision to preliminarily enjoin the Company from proceeding with the vote on the merger, to enjoin, pending the stockholder vote on the merger, the enforcement of the no-solicitation and matching right provisions in Section 6.5(b), (c) and (h) of the merger agreement, and the termination fee provisions relating to topping bids and changes of recommendation in Section 8.5(b) of the merger agreement. After a thorough discussion, the board of directors decided, among other things, to engage Perella Weinberg to proactively contact third parties who may be potentially interested in acquiring the Company. Such process is being conducted by Perella Weinberg at the direction of, and under the oversight of, the Strategic Committee of the board of directors. In connection with such services, Perella Weinberg will receive a retainer of $1,000,000 and an additional transaction fee of $4,000,000 in connection with the consummation of an alternative transaction, including a transaction with the sponsors, at a price per share of Company common stock higher than $19.00 per share.
