(collectively, the “Underwriters”) providing for the offer and sale (the “Offering”) in a firm commitment underwritten offering of an aggregate of 13,333,334 shares of the Company’s common stock, par value $0.01 per share (“Common Stock”), including 11,666,667 shares issued and sold by the Company and 1,666,667 shares sold by the Selling Shareholders at a price of $12.00 per share ($11.19 per share, net of underwriting discount, except with respect to certain Selling Shareholders selling 243,460 shares in the Offering issued upon exercise of stock options who were not required to pay underwriting discounts or commissions). Pursuant to the Underwriting Agreement, the Underwriters were granted an over-allotment option for a period of 30 days to purchase up to 700,000 additional shares of Common Stock from the Company and 1,300,000 additional shares of Common Stock from the Selling Shareholders, at the same price per share, to cover over-allotments, if any. The material terms of the Offering are described in the prospectus, dated February 1, 2012 (the “Prospectus”), filed by the Company with the Securities and Exchange Commission (the “Commission”) on February 2, 2012 pursuant to Rule 424(b)(4) under the Securities Act of 1933, as amended (the “Securities Act”). The Offering was registered with the Commission pursuant to a Registration Statement on Form S-1, as amended (File No. 333-176263), initially filed by the Company on August 12, 2011.

In the Underwriting Agreement, the Company and the Selling Shareholders agreed to indemnify the Underwriters against certain liabilities, including liabilities under the Securities Act, and to contribute to payments the Underwriters may be required to make because of any of those liabilities.

As described under the caption “Underwriters” in the Prospectus, certain of the Underwriters have, from time to time, performed, and may in the future perform, various financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities for the Company for which they have received and in the future will be entitled to receive, customary fees and reimbursement of expenses. Affiliates of Comerica Securities, Inc. are counterparties to the Company’s hedging arrangements and provide commercial banking services for the Company’s treasury management function. Affiliates of RBC Capital Markets, LLC, Citigroup Global Markets Inc. and Comerica Securities, Inc. are lenders, and Comerica Bank, an affiliate of Comerica Securities, Inc., acts as administrative agent for the lenders, under the Company’s amended and restated senior secured revolving credit agreement.
