Item 1.01. Entry into a Material Definitive Agreement

On December 16, 2009, we entered into an underwriting agreement (the “Underwriting Agreement”) with William Blair & Company, L.L.C., as book-running manager of the several underwriters (the “Underwriters”), relating to the sale by our company of a total of 3,000,000 shares of our common stock (the “Offering”). The offering price to the public was $9.70 per share. Net proceeds (after deducting the underwriting discounts but before expenses) will be approximately $27,499,500 to our company. The shares of common stock were offered and sold pursuant to a base prospectus and related prospectus supplement, which have been filed with the Securities and Exchange Commission. Pursuant to the Underwriting Agreement, we have granted the Underwriters a 30-day option to purchase up to an additional 450,000 shares of our common stock solely to cover over-allotments, if any.

The Underwriting Agreement contains customary representations, warranties, and conditions to closing. We have also agreed to indemnify the Underwriters against certain liabilities, including civil liabilities under the Securities Act of 1933, as amended, or to contribute to payments that the Underwriters may be required to make in respect of those liabilities. Subject to specified exceptions, we and each of our directors and officers, also agreed not to make an offer, sale, short sale, or other disposition of shares of common stock or other securities convertible into or exchangeable or exercisable for shares of common stock for 90 days after December 16, 2009 without first obtaining the written consent of William Blair & Company, L.L.C.

The foregoing description of the Underwriting Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Underwriting Agreement, a copy of which is attached hereto as Exhibit 1.1 and is incorporated by reference into this Item 1.01.

A copy of the opinion of Morrison & Foerster LLP relating to the legality of the issuance and sale of the shares in the Offering is attached hereto as Exhibit 5.1.
