(d) On September 30, 2010, the Board of Directors of the Company elected Nicole Vitullo as a director to fill the vacancy created upon Mr. Grey’s resignation. Ms. Vitullo was appointed to the Nominating and Corporate Governance Committee, was designated as a Class II member of the Board of Directors and was elected to serve until the Company’s 2011 Annual Meeting of Stockholders or until her successor is duly elected and qualified. Ms. Vitullo is a managing member of One Palmer Square Associates VIII, LLC (“Domain”). As previously disclosed, in connection with Domain’s agreement to invest in the Company, the Company agreed that Ms. Vitullo would be appointed to the Board of Directors upon a vacancy. On August 18, 2010 Domain purchased an aggregate of 8,032,129 shares of common stock of the Company and warrants to purchase 2,811,245 shares of common stock of the Company. Upon exercise of the warrants, Domain will beneficially own approximately 17.7% of the Company’s total issued and outstanding shares.

Upon her election, and in accordance with the Company’s standard director compensation policy, the Board of Directors granted Ms. Vitullo an option to purchase 25,000 shares of the Company’s common stock, pursuant to the Company’s 2006 Stock Incentive Plan. The stock options granted to Ms. Vitullo are immediately vested and exercisable and have an exercise price equal to the closing price of the Company’s common stock reported on the NASDAQ Global Market on September 30, 2010. In addition, Ms. Vitullo will receive fees for attending board and committee meetings, each in accordance with the Company’s director compensation policy.
