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)	Shares acquired pursuant to conversion of Restricted Stock Units (RSUs) on a one-for-one basis. RSUs issued pursuant to issuer's Management Stock Purchase Plan (MSPP) under which executive may make an advance election to receive RSUs in lieu of specified percentage or dollar amount of annual incentive cash bonus under bonus plan applicable to executive. The RSUs were issued on 3/5/2004. 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 ($15.92 in this case) and generally vest 3 years from date of the grant, at which time they convert into shares of common stock unless the executive has previously selected a longer deferral period. Acquisition price reflected is based on a 33% discount to fair market value of issuer's stock to grant date. Transactions reported herein reflect the conversion of RSUs into shares and withholding of sufficient shares to pay taxes.
(2)	Fair market value of shares, based on closing price of issuer's stock on March 2, 2007 is $34.00 (last business day before vesting).
