        <footnote id="F1">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.</footnote>
        <footnote id="F2">Original exercise price of $20.88 does not reflect adjustments for stock splits and stock dividends declared after the
 original date of grant.</footnote>
