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 Restricted Stock Units (RSUs), the conversion of which are reported herein, were issued to the reporting person pursuant to the issuer's Management Stock Purchase Plan (MSPP) on February 12, 2003. On that date, the fair market value of a share of the issuer's stock was $15.00. Under the MSPP, directors may make an advance election to receive RSUs in lieu of a specified percentage or dollar amount of the director's annual retainer. RSUs are issued in whole units on the basis of a 33% discount from the fair market value of the issuer's common stock on the date the underlying bonus is determined ($10.05 in this case) and generally vest 3 years from the date of the grant, at which time they convert into shares of common stock unless the director has previously selected a longer deferral period. The reporting person has elected to receive these RSUs in lieu of his entire annual director retainer fee of $27,500.
