Explanation of Responses:

( 1 )The number of securities reported in this row represents the total number of shares purchased by Reporting Person pursuant to the 2015 Officer Stock Ownership Program, a description of which can be found in the current report on Form 8-K filed with the Security Exchange Commission on February 20, 2015. ( 2 )This includes 248,390 unvested restricted stock units. ( 3 )Restricted Stock Unit ("RSU") grant pursuant to the 2015 Officer Stock Ownership Program (the "Program"). Reporting Person received a total of 5,882 RSUs, which is equal to 20% of the total shares purchased under the Program. Subject to the provisions of the 2007 Equity Incentive Plan, the RSU grant will vest on the one year anniversary of the date of grant (the "Vesting Date"), provided the Reporting Person does not assign, transfer, pledge or otherwise dispose of the purchased shares prior to the Vesting Date, and remains a Service Provider to the Company through the Vesting Date. ( 4 )$0.00 is used for technical reasons as there is no price for this security until it vests in the case of RSUs, or until it is exercised in the case of stock options. ( 5 )This includes 254,272 unvested restricted stock units. ( 6 )The forfeiture reported in this row represents restricted stock units that were withheld by the Company solely for the purpose of satisfying tax obligations arising upon the automatic vesting of 50,094 restricted stock units.
