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) The Company's Management Incentive Plan (MIP), an employee plan exempt under Section 16b-3, provides that employees participating in the plan are eligible to defer a portion of their annual bonus to purchase phantom stock units at a price per unit equal to the fair market value (FMV) of the Company's common stock on the date of purchase. The company will match a specified percentage of the phantom stock units purchased pursuant to the deferral program. Upon vesting, the Company will issue the underlying common stock.
(2) Units retained by the Company to satisfy cash deferral directly into the Company's 401 (K) Plan on the behalf of the reportee.
(3) Units retained by the Company to satisfy tax payment due for the behalf of the reportee.
(4) Cash-in-lieu of fractional share in connection with the conversion of units to underlying stock.
(5) On the third anniversary of the employee's deferral, the Company will issue the underlying common stock. Alternatively, on the third anniversary of the employee's deferral, the employee may elect to redefer the bonus units for another three year period and every three years thereafter, until the earlier of normal retirement or termination. The entire Company match is forfeited if the employee's employment terminates prior to the third anniversary of the employee's deferral.
(6) These units have vested and have been converted under the terms of the plan.
(7) Price not applicable.
