Explanation of Responses:

( 1 )In September 2011 the Company issued an award of 75,000 shares of common stock (the "2011 Shares") from the Company's 2011 Equity Incentive Plan to Mr. Harmon (the "2011 Award"). All of the 2011 Shares were subject to a right of repurchase by the Company at a price of $0.0001 per share upon the termination of Mr. Harmon's employment or other circumstances designated in the 2011 Award agreement. The right of repurchase over the 2011 Shares was to expire ratably and on a quarterly basis over the period beginning on October 1, 2012 and ending on June 30, 2015. On December 28, 2012, the Company amended the 2011 Award, reducing the number of shares subject to the 2011 Award from 75,000 shares of common stock to 12,500 shares of common stock. The amended total of 12,500 of the 2011 Shares are fully vested and no long subject to a repurchase right in favor of the Company. ( 2 )The Company has a right of repurchase on 60,000 shares at a price of $0.0001 per share upon the termination of Mr. Harmon's employment or other circumstances designated in the Award agreement. These repurchase rights expire at the rate of 4,000 shares per calendar quarter, beginning on March 31, 2013 and ending on September 30, 2016. ( 3 )The Form 4 filed on January 18, 2013 incorrectly stated the number of shares of common stock owned by Mr. Harmon following the reported transactions.
