(collectively, the "Funds). HMI LLC and the Funds are directors by deputization of the Issuer. The 10,369 shares held directly by HMI LLC were granted to Mr. Hellman under the Issuer's Amended and Restated 2010 Omnibus Equity Incentive Plan pursuant to the Issuer's Non-Employee Director Compensation Policy. Mr. Hellman assigned these shares to HMI LLC. The proceeds of any disposition of these shares will be applied against management fees payable pursuant to the partnership agreement of the applicable fund.

As the managing member of HMI LLC and a member of the investment committee, Mr. Hellman may be deemed to indirectly beneficially own such shares. Mr. Hellman disclaims beneficial ownership of such shares except to the extent of his pecuniary interest therein, if any.
(3) The Funds hold shares for the benefit of their investors. Such shares may be deemed to be indirectly beneficially owned by HMI LLC as the general partner and investment adviser of the Funds and by Mr. Hellman as the control person of HMI LLC. Mr. Hellman disclaims beneficial ownership of such shares except to the extent of his pecuniary interest therein.
