Explanation of Responses:

1. One of Ms. Denholm's private investment managers purchased 21 shares of the Company's common stock on May 18, 2011 and sold 6 shares and 15 shares of the Company's common stock on June 6, 2011 and June 7, 2011, respectively. Ms. Denholm delegated all investment decisions in this account to this private investment manager and the private investment manager used its discretion to consummate these purchase and sale transactions without Ms. Denholm's knowledge or approval and contrary to instructions provided by Ms. Denholm to her investment management firm, an affiliate of the private investment manager, prohibiting transactions in the Company's common stock. Ms. Denholm has subsequently re-iterated her instructions to the private investment manager prohibiting transactions in the Company's common stock.
