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) On 10/01/01 the reporting person was granted an option to purchase 849 shares of the Issuer's Common Stock at a purchase price of $16.14 per share. This option had an exercise price which was less than the closing price of the company's common stock on the appropriate measurement date determined by a special committee of the company's Board of Directors and the Company for financial accounting purposes. The Company has agreed to amend this misdated option to increase the exercise price to the appropriate fair market value per share on the correct measurement date ($16.64) so as to avoid adverse tax consequences under Internal Revenue Code 409A, and as applicable, similar provisions of state law. The Company and the reporting person entered into a Stock Option Amendment Agreement to amend this option.
(2) This option is fully vested and exercisable.

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