Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Employee Stock Option (right to buy)
(2) As previously reported on a Form 4 filed on June 4, 2012 by the reporting person, the reporting person reported acquiring stock options to purchase 350,877 shares of common stock pursuant to the company's 2010 Stock Option and Award Plan (the "Plan"). However, the company subsequently determined that stock options to purchase 12,733 shares of common stock were not validly granted pursuant to the Plan because such options, when combined with other awards to the reporting person, exceeded the limit on the number of common shares with respect to which awards may be awarded during a calendar year under the Plan to an employee. Accordingly, the attempted grant of these excess stock options was ineffective, and they were never granted to the reporting person. The reporting person is filing this amendment to report the correct amount of stock options acquired.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
