         Set forth below is a transcript of an e-mail message sent to employees
of Cullen/Frost Bankers, Inc. ("Cullen/Frost") on April 29, 2003. Also set forth
below is a revised version of the Summary Compensation Table that appeared on
page 13 of Cullen/Frost's Definitive Proxy Statement on Schedule 14A, which was
filed with the Securities and Exchange Commission on April 16, 2003. The revised
version of the table corrects an inadvertent and erroneous overstatement of the
2002 salaries of Messrs. T.C. Frost, Phillip D. Green and Patrick B. Frost.

                      MESSAGE TO EMPLOYEES OF CULLEN/FROST

         Through an inadvertent administrative error, the Summary Compensation
Table on page 13 of the CFR Proxy Statement incorrectly overstated the 2002
salaries for T.C. Frost, Phil Green and Pat Frost. The 2002 salaries listed
should have been the same as the 2001 salaries, as there was no increase. This
correction is being filed with the Securities and Exchange Commission. If you
have any questions, please feel free to contact me.

         income taxes on elective deferrals and Company matching contributions
         to Cullen/Frost's 1991 Thrift Stock Purchase Plan (the "1991 Thrift
         Plan"), which provides benefits comparable to the Company's 401(k)
         Stock Purchase Plan for employees whose participation in the 401(k)
         Plan is limited by IRS rules. Mr. T.C. Frost's values represent the
         total reimbursement to him for taxes on life insurance premiums paid by
         the Company. Mr. Evans' values include $12,693 to reimburse him for
         taxes on life insurance premiums paid by the Company and a $6,000
         automobile allowance.

(2)      Represents the dollar value of restricted stock awards, based on the
         closing market price of Company Common Stock on the grant date. The

         31, 2002 of the named executive officers are as follows: Mr. T.C.
         Frost, 0 shares; Mr. Evans 31,875 shares valued at $1,042,313; Mr.
         Green 9,250 shares valued at $302,475; and Mr. P. Frost 8,000 shares
         valued at $261,600. Aggregate market value is based on the closing
         market price of Company Common Stock on December 31, 2002, which was
         $32.70. Dividends are paid on the restricted shares at the same time
         and at the same rate as dividends paid to shareholders of unrestricted

         from the date of the award.

(3)      Represents total and/or imputed income from certain insurance premiums
         paid by Cullen/Frost and the Company's contributions to the 1991 Thrift
