Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Acquired through the Company's Employee Stock Purchase Plan (ESPP).
(2) Represents a restricted stock unit award granted to the reporting person for service as an executive officer of the Company, which will vest in full on February 18, 2009.
(3) Represents a restricted stock unit award granted to the reporting person for service as an executive officer of the Company, which will vest in full on February 18, 2011.
(4) Restricted stock unit award consisting of a base and a bonus amount of shares, each representing 50% of the total award. The bonus amount constitutes an incremental number of shares that, when added to the base shares, equals the maximum number of shares of restricted stock that the reporting person may receive based on the relative stock price performance of the Company and certain of its public peers for the 3-year period ending 2/18/2011.
(5) The actual amount of shares that will finally be received by the reporting person will be calculated as a percentage of the base shares amount as follows: (1) Top 20% = 200% of base shares; (2) Top 33-1/3%=between 150% and 200% of base shares; (3) Top 50% = between 100% and 150% of base shares; (4) Top 66-2/3% = between 50% and 100% of base shares; and (5) Bottom 33-1/3% = no shares. Within categories (2), (3) and (4), the appropriate bonus and forfeiture factors related to the base shares amount will be interpolated on a straight-line basis between the two performance percentages.
