The original Form 4, filed with the SEC on behalf of the reporting person on February 19, 2013, erroneously overstated the number of shares of common stock withheld by the Company to satisfy tax withholding obligations in connection with the vesting of restricted stock units and did not reflect the number of shares sold by the reporting person to the Company to cover the tax withholding in excess of the federal required rate in accordance with the 2008 Stock Incentive Plan. This amendment to the original Form 4 corrects these errors and reflects the corrected amount of securities beneficially owned following each reported transaction. Vesting of restricted stock unit grant dated February 15, 2011 pursuant to the Plan. Vesting of restricted stock unit grant dated February 15, 2012 pursuant to the Plan. Represents shares issued in settlement of vesting of performance restricted stock unit grant dated March 15, 2010 pursuant to the Plan. Represents shares issued in settlement of vesting of performance restricted stock unit grant dated February 15, 2011 pursuant to the Plan. Represents shares issued in settlement of vesting of performance restricted stock unit grant dated February 15, 2012 pursuant to the Plan. /s/ Kelli A. Mowry, Attorney-in-Fact 2013-03-29
