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 two reported transactions involved an amendment of an outstanding option to accelerate vesting upon Mr. Wiley's retirement as President and Chief Executive Officer of CVB Financial Corp. and extension of the term of exercisability of the option from its former expiration date of 90 days following retirement to the date which is the natural expiration date of the option. The option originally granted on March 17, 2004 provided for vesting in five equal annual installments commencing on March 17, 2005 and expiration 90 days after retirement.
