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) Restricted stock award subject to forfeiture based on the relative stock price performance of HOS and certain of its public peers for the 3-year period ending 2/14/2009. The above shares represent the maximum amount of shares that may be received by the reporting person under the bonus and forfeiture provisions of this long-term incentive grant. The actual amount of shares finally received will be calculated as a percentage of the "Base" amount (equal to 50% of the above amount) based on the relative performance ranking of HOS compared to its peers, as follows: (1) Top 20% = 200% of Base; (2) Top 33-1/3% = between 150% and 200% of Base; (3) Top 50% = between 100% and 150% of Base; (4) Top 66-2/3% = between 50% and 100% of Base; and (5) Bottom 33-1/3% = no shares. Within categories (2), (3) and (4), the appropriate bonus and forfeiture factors related to the Base amount will be interpolated on a straight-line basis between the two performance percentages.
(2) The option provides for vesting in three equal annual installments commencing on 02/14/2007.
