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)	Stock options were granted to the reporting person. Vesting will occur annually from the date of grant over 4 years with 25% vesting each year.
(2)	The reporting person was granted restricted stock units (RSUs) which are subject to performance-based vesting. The RSUs are effective as of 4/29/08, and will vest on 12/3/2010, based on the level of return on average equity (ROE) as reported on the company's 2008 financial statements as follows: (i) none will vest if less than 90% of target ROE is achieved; (ii) 50% will vest if 90% but less than 100% of target ROE is achieved; (iii) 100% will vest if 100% but less than 110% of target ROE is achieved, and; and (iv) 150% of the award will vest if 110% or greater of target ROE is achieved. The reported number of shares on this form is based on achievement of 110% or greater of target. Vesting is also subject to the Company meeting certain expense control targets. The Compensation Committee of the Board of Directors will have the discretion to adjust the performance targets to take into account any extraordinary items.

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