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) This represents the difference between the number of SARs exercised (5,167) and the number of shares issued as a result of the exercise (1,856). The number of shares to be issued under a SAR exercise is determined by multiplying the number of SARs being exercised by the difference between the FMV on the date of exercise ($25.465) and the exercise price ($11.92). Additional shares are then withheld to satisfy the Company's tax withholding obligations.
(2) The options became exercisable in three equal annual installments on February 23, 2005, February 23, 2006 and February 23, 2007.
(3) 5,167 SARs became exercisable on February 24, 2010. The remaining 10,333 SARs will become exercisable in equal installments on February 24, 2011 and February 24, 2012.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
