EXPLANATORY NOTE

The registrant filed with the Securities and Exchange Commission (the SEC) an Annual Report on Form 10-K for the year ended
December 31, 2012 (Original Form 10-K) on February 22, 2013. The Original Form 10-K was the registrants first Form 10-K containing managements report on internal control over financial reporting. However the
registrant inadvertently omitted certain required language from paragraph 4 of the certifications of the registrants principal executive officer and principal financial officer required by Exchange Act Rule 13a-14(a), as adopted pursuant to
Section 302 of the Sarbanes-Oxley Act of 2002.

This Amendment No. 1 on Form 10-K/A is being filed solely for the purpose of
filing revised certifications by the registrants principal executive officer and principal financial officer, including the previously omitted language. These revised certifications are currently dated, refer to this Form 10-K/A, and are being
included as exhibits to this Amendment No.1 on Form10-K/A under Part IV, Item 15 hereof. In accordance with interpretation 246.13 in the Regulation S-K section of the SECs Compliance & Disclosure Interpretations, this
Form 10-K/A contains only the cover page, this explanatory note, a signature page, and the revised certifications (containing only paragraphs 1, 2, 4 and 5 of the text otherwise prescribed by Item 601(b)(31)(i) of Regulation S-K).

Except as described above, no attempt has been made in this Amendment No.1 on Form 10-K/A to modify or update the other disclosures or
exhibits presented in the Original Form 10-K. Except as presented in this Form 10-K/A and except for Exhibits 31.1 and 31.2 filed herewith, this Amendment No. 1 on Form 10-K/A does not reflect events occurring after the filing of the Original
Form 10-K, or modify or update those disclosures. Accordingly, this Amendment No. 1 on Form 10-K/A should be read in conjunction with the Original Form 10-K and the registrants other filings with the SEC.
