FORM 10-K/A

Explanatory Note

     This Amendment No. 1 on Form 10-K/A (the “Amendment”) amends the Annual Report on Form 10-K (the “Original Annual Report”) for the year ended December 31, 2011, which was originally filed with the Securities and Exchange Commission (the “SEC”) on March 7, 2012. We are filing this Amendment in response to a comment letter received from the SEC (the “Comment Letter”) in connection with its review of our confidential treatment request for certain omitted portions of Exhibit 10.36, our office lease agreement with Exponent Realty, LLC, dated February 29, 2012. We have modified Part IV Item 15, “Exhibits, Financial Statement Schedules,” in this Amendment to reflect that confidential treatment for Exhibit 10.36 has been requested and re-filed Exhibit 10.36 in response to the Comment Letter to include Exhibits A – F of the lease agreement and disclose suite numbers, building rentable space, load factor and building percentage. We also have submitted a revised confidential treatment request in response to the Comment Letter. In addition, pursuant to Rule 12b-15 under the Securities Exchange Act of 1934, as amended, new certifications by our principal executive officer and principal financial officer are filed as Exhibits 31.3 and 31.4, respectively, to this Amendment.

     Except as described above, no attempt has been made in this Amendment to modify or update other disclosures presented in the Original Annual Report. This Amendment does not reflect events occurring after the filing of the Original Annual Report or modify or update those disclosures, including the exhibits to the Original Annual Report affected by subsequent events. Accordingly, this Amendment should be read in conjunction with our filings with the SEC subsequent to the filing of the Original Annual Report, including any amendments to those filings.
