under the Securities Act of 1933, as amended (the &#147;Act&#148;). The Registration Statement relates to the offering and sale by the Company of up to 3,750,000 shares of the Company&#146;s Common Stock, par value $0.01 per share (the &#147;Common
Stock&#148;), to be issued pursuant to equity awards (&#147;Awards&#148;) granted or to be granted under the Company&#146;s Amended and Restated 2008 Incentive Compensation Plan (the &#147;2008 Plan&#148;). We have acted as counsel to the Company in

if any, required to be paid in connection with the issuance of underlying shares of Common Stock issued pursuant to Awards is actually received by the Company as provided in any such Award, the shares of Common Stock issued pursuant to the Plan will
