istered assigns, is the registered holder of the number of 
Rights set forth above, each of which entitles the regis-
tered holder thereof, subject to the terms, provisions and 
conditions of the Shareholder Protection Rights Agreement, 
dated as of January 26, 1999 (as amended from time to time, 
the "Rights Agreement"), between Cullen/Frost Bankers, Inc., 
a Texas corporation (the "Company"), and The Frost National 
Bank, as Rights Agent (the "Rights Agent", which term shall 
include any successor Rights Agent under the Rights 
Agreement), to purchase from the Company at any time after 
the Separation Time (as such term is defined in the Rights 
Agreement) and prior to the close of business on February 8,

tion to Exercise duly executed at the principal office of 
the Rights Agent in San Antonio, Texas.  The Exercise Price 
shall initially be $200 per Right and shall be subject to 
adjustment in certain events as provided in the Rights 
Agreement.  
          In certain circumstances described in the Rights 
Agreement, the Rights evidenced hereby may entitle the reg-
istered holder thereof to purchase securities of an entity 
other than the Company or securities of the Company other 
than Preferred Stock or assets of the Company, all as 
provided in the Rights Agreement.
          This Rights Certificate is subject to all of the 
terms, provisions and conditions of the Rights Agreement, 
which terms, provisions and conditions are hereby incorpo-
rated herein by reference and made a part hereof and to 
which Rights Agreement reference is hereby made for a full

          This Rights Certificate, with or without other 
Rights Certificates, upon surrender at the office of the 
Rights Agent designated for such purpose, may be exchanged 
for another Rights Certificate or Rights Certificates of 
like tenor evidencing an aggregate number of Rights equal to 
the aggregate number of Rights evidenced by the Rights 
Certificate or Rights Certificates surrendered.  If this 
Rights Certificate shall be exercised in part, the reg-
istered holder shall be entitled to receive, upon surrender 
hereof, another Rights Certificate or Rights Certificates 
for the number of whole Rights not exercised.
          Subject to the provisions of the Rights Agreement, 
each Right evidenced by this Certificate may be (a) redeemed 
by the Company under certain circumstances, at its option, 
at a redemption price of $0.01 per Right or (b) exchanged by 
the Company under certain circumstances, at its option, for 
one share of Common Stock or one one-hundredth of a share of 
Preferred Stock per Right (or, in certain cases, other 
securities or assets of the Company), subject in each case 

                           -3-


to adjustment in certain events as provided in the Rights 
Agreement.
          No holder of this Rights Certificate, as such, 
shall be entitled to vote or receive dividends or be deemed 
for any purpose the holder of any securities which may at 
any time be issuable on the exercise hereof, nor shall 
anything contained in the Rights Agreement or herein be 
construed to confer upon the holder hereof, as such, any of 
the rights of a shareholder of the Company or any right to 
vote for the election of directors or upon any matter 
submitted to shareholders at any meeting thereof, or to give 
or withhold consent to any corporate action, or to receive 
notice of meetings or other actions affecting shareholders 
(except as provided in the Rights Agreement), or to receive 
dividends or subscription rights, or otherwise, until the 
Rights evidenced by this Rights Certificate shall have been 
exercised or exchanged as provided in the Rights Agreement.

obligatory for any purpose until it shall have been counter-
signed by the Rights Agent.
