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 RSUs reported represent an adjustment to a target number of RSUs previously awarded on March 15, 2006. The actual number finally awarded depended upon the achievement of certain 2006 performance criteria set by the Compensation Committee. On February 15, 2007, the Committee finally determined the achievement of the 2006 performance criteria; accordingly, 164.5% of the target number of RSUs was the number of RSUs finally awarded. The number of RSUs reported on this filing represents the difference between the actual number finally awarded and the target number previously reported. The RSUs vest in four equal annual installments, beginning on May 15, 2007.
(2)	The stock appreciation right becomes exercisable in four substantially equal annual installments commencing on 2/15/2008.
