(1) On September 8, 2010, Diamond Acquisition Corp. ("Diamond"), a Delaware corporation and wholly owned subsidiary of the Reporting Person, accepted for payment 28,457,901 shares of common stock, par value $0.01 (the "Shares"), of Issuer pursuant to an offer to purchase all of the outstanding Shares (the "Offer"). The Offer was made pursuant to an Agreement and Plan of Merger, dated as of August 6, 2010, by and among Diamond Acquisition Corp. ("Diamond"), the Reporting Person and the Issuer (the "Merger Agreement").
(2) The Offer expired at 12:00 midnight, New York City time, on Wednesday, September 8, 2010. An aggregate of 28,457,901 Shares were validly tendered and not withdrawn prior to the expiration of the Offer, representing approximately 92.4% of the Shares outstanding. On September 8, 2010, Diamond accepted for payment all Shares that were validly tendered in the Offer and not withdrawn and promptly made payment for such Shares in accordance with the terms of the Offer and applicable law.
(3) Diamond is a wholly owned subsidiary of the Reporting Person, and as a result Diamond and the Reporting Person may have been deemed (prior to the Merger) to share beneficial ownership of the Shares shown as beneficially owned by the Reporting Person.
