This Amendment No. 1 to Schedule 13D amends and supplements items 4(a), 5 and 6 contained in the Schedule 13D initially filed with the Securities and Exchange Commission on or about May 1, 2008 (the “Initial 13D”). Capitalized terms used herein but not defined shall have the meanings ascribed to them in the Initial 13D. The Initial 13D is amended and supplemented as follows.

Item 4. Purpose of Transaction

(a) This Schedule 13D is being filed due to the forfeiture of employee stock options to purchase 180,000 shares of Common Stock at an exercise price of $17.00 per share (the “$17.00 Options”) granted to the Reporting Person in exchange for 90,000 shares of unvested Common Stock granted pursuant to the Company’s 2005 Stock Incentive Plan and a restricted stock award agreement. The Company granted the $17.00 Options to the Reporting Person in conjunction with the commencement of his employment with the Company and pursuant to a stock option agreement. The $17.00 Options vested and became exercisable with respect to 15% of the shares on the first anniversary of the grant date, 25% of the shares on the second anniversary of the grant date and 25% of the shares on the third anniversary of the grant date, and an additional 35% of the shares would have become vested and exercisable on the fourth anniversary of the grant date, at which time the granted options would have been fully vested and exercisable. Of the 90,000 shares of unvested Common Stock received by the Reporting Person, 12.5% will vest on each of first, second, third and fourth anniversary of the grant date, and the remaining 50% will vest on the fifth anniversary of the grant date.

Item 5. Interest in Securities of Issuer

(a) and (b) The Reporting Person beneficially owns 293,584 shares of Common Stock, which includes 90,000 shares of unvested Common Stock held directly received pursuant to a restricted stock award described in Item 6 below, and options to acquire 146,250 shares of Common Stock that vested as follows: 33,750 shares on February 28, 2006, 56,250 shares on February 28, 2007 and 56,250 shares on February 28, 2008.

The Reporting Person’s current beneficial ownership represents approximately 4.9% of the shares of the Common Stock, based upon 5,796,994 shares of Common Stock issued and outstanding as of September 8, 2008 (including 533,350 shares of Common Stock to be issued pursuant to restricted stock awards, including to the Reporting Person), plus 146,250 shares of Common Stock which may be received upon exercise of options beneficially owned by the Reporting Person. The Reporting Person has sole voting and dispositive power over the shares of Common Stock reported as beneficially owned by him.

(c) Except as set forth herein the Reporting Person has not effected any transactions in shares of the Common Stock during the past 60 days.

(d)

None.

(e) By virtue of the transaction reported herein, the Reporting Person ceased to be a beneficial owner of more than 5% of the outstanding Common Stock on September 8, 2008, assuming the issuance of the 533,350 shares of Common Stock granted pursuant to restricted stock award agreements, including to the Reporting Person, entered into as of September 8, 2008, as reported in the Company’s current report on Form 8-K filed on September 11, 2008.

Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to the Securities of the Issuer

On September 8, 2008, the Reporting Person received, pursuant to a restricted stock award, 90,000 shares of unvested Common Stock, which will vest in the following increments: 12.5% on each of the first, second, third and fourth anniversary of the grant date, and the remaining 50% on the fifth anniversary of the grant date.
