             PROXY STATEMENT FOR THE ANNUAL MEETING OF SHAREHOLDERS
                           TO BE HELD ON MAY 28, 1997
- --------------------------------------------------------------------------------
 
                      SOLICITATION AND REVOCATION OF PROXY
 
     This Proxy Statement is furnished in connection with the solicitation by
the Board of Directors of Cullen/Frost Bankers, Inc. ("Cullen/Frost" or the
"Company") of proxies to be used at the Annual Meeting of Shareholders. The
meeting is scheduled to be held on May 28, 1997, in accordance with the attached
notice. This Proxy Statement and the accompanying proxy card are being mailed to
shareholders beginning on or about April 17, 1997.
 
     Cullen/Frost will bear the cost of solicitation of proxies for the Annual
Meeting. In addition to solicitation by mail, the directors, officers, and
employees of Cullen/Frost may solicit proxies by telephone, telegram, facsimile,
or in person. Cullen/Frost also has retained Georgeson & Co., Inc. to assist in
the solicitation of proxies, for a fee of approximately $8,500 plus
out-of-pocket expenses. Brokers, nominees, fiduciaries, and other custodians
have been requested to forward proxy soliciting material to the beneficial
owners of Cullen/Frost Common Stock, and Cullen/Frost will reimburse them for
their out-of-pocket expenses.
 
     All shares of Cullen/Frost Common Stock represented by properly executed
proxies, if returned in time, will be voted at the meeting in accordance with
the instructions indicated thereon. If no direction is given, proxies will be
voted for the election as directors of the nominees referred to in Item 1 of the
Proxy Statement; in favor of the proposal to amend the Articles of Incorporation
to increase the authorized shares of common stock as described in Item 2 of the
Proxy Statement; in favor of the amendments to the 1992 Stock Plan as described
in Item 3 of the Proxy Statement; in favor of the 1997 Directors Stock Plan as
described in Item 4 of the Proxy Statement; in favor of the proposal to approve
the selection of Ernst & Young LLP as independent auditors described in Item 5
of the Proxy Statement; and in the discretion of persons named on the proxy in
connection with any other business that may properly come before the meeting.
Shares represented by properly executed proxies, if returned in time, will be
counted for purposes of determining the number of shares present at the meeting,
even if authority to vote on any particular matter is withheld. A shareholder
may revoke a proxy at any time before it is voted by delivering a written
revocation notice at the Company's principal executive office to the Secretary
of Cullen/Frost, Ms. Diane Jack, 100 West Houston Street, San Antonio, Texas
78205. A shareholder who attends the meeting may vote by ballot at the meeting
if desired, and such vote will cancel any proxy vote previously given.
 
                              VOTING OF SECURITIES
 
     The only class of voting securities of Cullen/Frost outstanding and
entitled to vote at the meeting is Common Stock, par value $5.00 per share. On
April 4, 1997, the record date for determining shareholders of Cullen/Frost
entitled to vote at the meeting, there were outstanding 22,507,928 shares of
Common Stock, each entitled to one vote. Directors are elected by a plurality of
the votes cast by the holders of shares of Common Stock. Action to be taken on
Item 2 requires the affirmative vote of at least two-thirds of the outstanding
shares. Action to be taken on Items 3, 4 and 5 will be determined by a majority
of the shares of Common Stock present. Because abstentions are considered shares
present, proxies which are marked "abstain" will be the equivalent of a negative
vote in determining whether a majority vote was obtained for Item 3, 4 and 5.

                             ELECTION OF DIRECTORS
                             (ITEM 1 ON PROXY CARD)
 
     The Corporation's Bylaws provide for a classified Board of Directors under
which there are three classes of directors, all of which are as equal in number
as possible. The class to which each director has been assigned is designated as
Class I, Class II, or Class III. The term of office of Class I will expire at
this 1997 Annual Meeting, Class II at the 1998 Annual Meeting and Class III at
the 1999 Annual Meeting.
 
     The six current directors assigned to Class I have been nominated to stand
for re-election as directors at the Annual Meeting in 1997 for a three-year
term. In addition, there are four new nominees, Bob Coleman, Patrick Frost,
Joseph Fulton and Horace Wilkins, Jr. who stand for election. Each of the four
new nominees are currently members of The Frost National Bank Board. Although
Cullen/Frost management does not contemplate that any nominee will be unable to
serve, if such a situation arises prior to or at the meeting, the persons named
in the accompanying proxy will vote in accordance with their best judgment
unless otherwise instructed.
 
     Below is biographical information about each nominee and each director
whose term continues after the meeting, including age, recent business
experience and/or position with the Company. Also included is the Class in which
such director will serve and information on the nominees' and directors'
ownership of Cullen/Frost Common stock.

                 EXECUTIVE COMPENSATION AND RELATED INFORMATION
 
1. BOARD COMPENSATION AND BENEFITS COMMITTEE REPORT ON EXECUTIVE COMPENSATION
 
     The Compensation and Benefits Committee of the Board of Directors (the
"Committee") is committed to maintaining compensation programs for the Company's
executive officers which further the Company's mission. We, therefore, adhere to
the following compensation policies which are intended to facilitate the
achievement of the Company's business strategies:
 
     - Compensation levels for each element of pay should be targeted at rates
       that are reflective of the median levels of current market practices
       prevalent in comparable financial organizations. Offering
       market-comparable pay opportunities allows the Company to attract and
       maintain a stable, successful management team.
 
     - Executives' total compensation packages should strengthen the
       relationship between pay and performance with variable, at-risk
       compensation that is dependent upon the level of success in meeting
       specified Company and individual performance goals.
 
     - Ownership of the Company's Common Stock by executives should be
       encouraged to further align executives' interests with those of
       shareholders and the Company and to promote a continuing focus on
       building profitability and shareholder value.
 
     - Sustained superior performance by individual executives over a period of
       years, including actions to increase revenues, reduce expenses, enhance
       service and product quality, improve market share and thereby enhancing
       shareholder value, should be rewarded.
 
     To preserve objectivity in the achievement of its goals, the Committee is
comprised of five independent, nonemployee directors and one independent,
non-employee advisory director. It is the Committee's overall goal to develop
compensation policies that are consistent with and linked to strategic business
objectives and Company values. The Committee approves the design of, assesses
the effectiveness of, and administers compensation programs in support of
compensation policies. The Committee also reviews all salary arrangements and
other remuneration for a group of senior executives, including all those named
in the Summary Compensation table on page 10.
 
     Each year a comprehensive analysis of competitive market data is provided
by an independent compensation consultant engaged by, and responsible to, the
Committee. The data provided compares the Company's compensation practices and
programs to a group of comparator companies. This group of comparator companies
is comprised of companies who have business operations, total assets, market
capitalizations, and lines of business similar to the Company.
 
     These companies include, but are not limited to, the companies included in
the Standard & Poor's ("S&P's") Major Regional Bank Index. The Committee has
chosen not to use the S&P's Major Regional Bank Index as its comparator group
for compensation purposes since detailed data for all senior executives at the
banks comprising the index is not available.
 
     The S&P's Major Regional Bank Index was used for comparison of total
shareholder return shown in the Performance Graph on page 15.
 
     The key elements of the Company's executive compensation are base salary,
annual incentives, and long-term compensation. These key elements are addressed
separately below. In determining compensation, the Committee considers all
elements of an executive's total compensation package, including severance
plans, insurance, and other benefits.

- --------------------------------------------------------------------------------
 
BASE SALARIES
 
     Base salaries constituted approximately 69% of total executive compensation
for 1996. The Committee believes that the demonstration of superior abilities
and performance by individual employees should be rewarded, in part, through
salary reviews. The Committee reviews the base salary of each of the four
highest-paid executives on an annual basis.
 
     Base salaries may be adjusted after an evaluation of each executives'
performance in conjunction with a review of the median base pay received by
other individuals holding similar positions in the Company's comparator group.
Following the determination of the market-based pay, each officer's individual
performance, achievements, and contributions to the growth of the Company are
evaluated subjectively in determining the individual's base salary. Finally, the
overall performance and needs of the Company are examined and salaries may be
adjusted in response to the need to attract and retain appropriate officers. The
Company places no specific weights on the factors used in determining base
salary levels.
 
     Based on the factors listed above, base salaries approximated median market
levels of comparator companies in 1996, and merit increases were made at a rate
comparable to the increases provided at other companies.
 
     Effective July 1, 1994, Mr. Frost activated his retirement benefits while
continuing as Chief Executive Officer of the Company. Accordingly, his base
salary was reduced from $400,000 to $140,000. In determining Mr. Frost's base
salary for 1997, the Committee considered the Company's overall financial
performance for the year, Mr. Frost's individual performance and long-term
contributions to the success of the Company, and base salaries of CEOs at
comparator companies. Based on these factors, the Committee elected to increase
Mr. Frost's base salary to $200,000 which, in conjunction with his retirement
income, closely approximates a competitive level of base pay.
 
ANNUAL INCENTIVES
 
     Beginning in 1994, the Company initiated a formal annual incentive plan for
executives. Based on competitive target incentives at comparator companies, the
Committee determined target incentives by position and initiated a three-year
phase-in to these levels. The year 1996 was the final year of the three-year
plan. The Company must achieve a predetermined budget or target level of
financial performance before any bonuses are paid out. No bonus pool is
established if performance is below the targeted level, and only the target
bonus has been paid for performance at or above the targeted level. The
Committee has the authority to adjust payout as measured against financial
objectives up or down by 20 percent.
 
     In 1996, annual incentives accounted for approximately 14% of total
compensation earned by executives. The purpose of the annual incentive is to
promote and reward teamwork as measured by overall corporate performance while
recognizing individual contributions.
 
     The annual incentive target established for Mr. Frost is based on his
combined base salary and retirement income of $460,000, which closely
approximates the median base salary of CEOs at comparator companies. In
determining the annual incentive payment for Mr. Frost for 1996, the Committee
reviewed the financial results for the year and determined that the budgeted
level of performance, as measured by net income, had been exceeded. The
Committee then considered his leadership and contributions to the success of the
Company, and awarded Mr. Frost a bonus of $250,000. All other proxy reported
executive officers were awarded their target bonuses.
 
     For 1997, the Committee, in conjunction with management, reviewed the
current target bonus levels versus competitive market data (as measured by the
Comparator Group) and internal equity. The result was targets increased by
approximately 5% for selected positions. The Committee also elected to establish
an additional bonus pool for performance above the targeted level. The amount of
the pool will be determined by the Committee.

<PAGE>   10
 
- --------------------------------------------------------------------------------
 
LONG-TERM INCENTIVES
 
     The Committee believes that executive compensation should be dependent upon
the performance of the Company as a whole, as well as the performance of
individual executives. Long-term incentives are provided pursuant to the
Company's 1992 Stock Plan approved by the shareholders.
 
     In keeping with the Company's commitment to provide a total compensation
package which includes at-risk components of pay, long-term incentives
constituted approximately 17% of an executive's total compensation package in
1996.
 
     When awarding long-term incentives, the Committee considers executives'
levels of responsibility, prior experience, individual performance, and
compensation practices at comparator companies. The Committee's objective is to
provide executives with targeted long-term incentive opportunities that
approximate median levels at comparator companies. Current stock holdings and
the magnitude of outstanding long-term incentives are not considered in making
current awards.
 
STOCK OPTIONS
 
     Non-qualified stock options are granted at an option price not less than
the fair market value of the Common Stock on the date of grant. Accordingly, the
value of stock options is tied to appreciation in the stock price from the date
the options are granted. This design focuses executives on the creation of
shareholder value over the long term and encourages equity ownership in the
Company. Stock options are used as the primary long-term incentive vehicle.
 
     The size of stock option grants is determined based on a percentage of
annualized base salary. The size of the award can be adjusted based on the
Committee's subjective valuation of individual factors and historical award
data. The Compensation and Benefits Committee's objective is to deliver a
competitive award opportunity based on the dollar value of the award granted. As
a result, the number of stock options awarded varies from year to year and is
dependent on the stock price on the date of grant.
 
     In 1996, Mr. Frost received options to purchase 62,000 shares with an
exercise price of $30.25 as is detailed in the table on page 11. The grant
approximated the median level of comparator companies. Without giving effect to
such grants, Mr. Frost now has beneficial ownership of 746,747 shares of the
Company's common stock which includes 115,880 shares for which he has a right to
receive pursuant to presently exercisable employee stock options. With the 1996
grant, Mr. Frost holds options to purchase an additional 137,122 shares. Mr.
Frost's stock option grant was in keeping with the Committee's intent to place
emphasis on long-term compensation which is tied directly to the success of the
Company and, correspondingly, that of shareholders.
 
RESTRICTED STOCK
 
     Restricted stock provides executives with an immediate link to shareholder
interests and, due to vesting requirements, enhances the Company's ability to
maintain a stable executive team, focused on the Company's long-term success.
The Company has historically granted restricted stock every other year, with the
last grant of restricted stock occurring in 1995. No restricted stock was
granted to the named executives in 1996.
 
INTERNAL REVENUE CODE SECTION 162(M)
 
     Section 162(m) of the Internal Revenue Code generally limits the annual
corporate tax deduction for compensation paid to the Chief Executive Officer and
the four other most highly compensated executive officers unless the
compensation is performance-based. One condition to qualify compensation as
performance-based is to establish the amount of the award on an objective
formula that precludes any discretion, other than to adjust awards downward.

                                        8
<PAGE>   11
 
- --------------------------------------------------------------------------------
 
     The Committee continues to review the impact of this tax code provision on
the Company's incentive plans and has determined that Section 162(m) is
currently inapplicable because no named executive officer receives compensation
in excess of $1 million. In addition, the amendments to the 1992 Stock Plan
which are being submitted for shareholder approval (see item 3) will, if
approved, exclude compensation resulting from awards under the Plan, and which
would otherwise satisfy the requirements of Section 162(m) from being subject to
the limitation. The Committee also believes it is the Company's and
shareholders' best interests to retain the discretionary evaluation of
individual performance as provided in the annual incentive plan.
 
CONCLUSION
 
     The Committee believes these executive compensation policies and programs
serve the interests of shareholders and the Company effectively and that the
various pay vehicles offered are appropriately balanced to provide increased
motivation for executives to contribute to the Company's overall future
successes, thereby enhancing the value of the Company for the shareholders'
benefit.
 
     The Committee will continue to monitor the effectiveness of the Company's
total compensation program to meet the current needs of the Company.

2. COMPENSATION AND BENEFITS COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION IN
   COMPENSATION DECISIONS.
 
     During 1996, a loan originally established in the ordinary course of
business with a subsidiary bank and related to a director had subsequently been
reclassified as other assets. Summit Joint Venture II, of which Mr. Vaughan, a
Cullen/Frost director, is a limited partner, had debt to The Frost National Bank
which was originated to finance the purchase and development of real estate. The
largest amount outstanding during 1996 was $1,727,956. The debt was satisfied in
full on May 17, 1996. Interest charged was dependent upon debt repayment
amounts. Debt repayment was based on asset sales during the year.
 
     In the opinion of management, the above described transaction was effected
on terms comparable to those available to unaffiliated parties.

</TABLE>
 
     The Retirement Plan was revised effective January 1, 1993 to provide a
monthly benefit based on a percentage of an eligible employee's final average
Compensation based on the highest three years of compensation during the last
ten years of service. An eligible employee's Retirement Benefit will be the
greater of the employee's benefits accrued under the prior provisions of the
plan up to December 31, 1992 or the benefits determined by the new formula
effective January 1, 1993. Included in "Compensation" according to the
Retirement Plan are Salary, Overtime, Bonuses, Commissions and Wages deferred
for the Company 401(k) Plan or used to pay health care premiums and expenses
which are not reimbursable under the company Pre Tax Plan (IRS section 125
Plan). Participants in the Plan are fully vested in their accrued benefits under
the Plan upon attaining age 65 or after five years of service, whichever occurs
first. Death benefits are provided to married participants who have completed
five years of service. Normal retirement is at age 65 but early retirement is
available starting at age 55. Early Retirement benefits are reduced on an
actuarial basis. The benefit amounts listed in the table represent amounts
payable from the plans and are not subject to any additional deduction for
social security benefits or other offset amounts.
 
     The years of credited service under the Retirement Plan as of December 31,
1996 for each person named in the Summary Compensation Table on page 10 are: Mr.
T. C. Frost -- 47 years; Mr. Evans -- 26 years (40 years at age 65); Mr.
McClane -- 34 years (41 years at age 65); and Mr. Green -- 16 years (39 years at
age 65). Mr. Frost activated his retirement benefit effective July 1, 1994, but
still remains an active employee. Each year, his retirement benefits will be
recalculated based on his earnings for that year.
 
     The Company also maintains a supplemental executive retirement plan
("SERP"). The plan provides for target retirement benefits, as a percentage of
annual cash compensation, beginning at age 55. The target percentage is 45% of
annual cash compensation at age 55, increasing to 60% at age 60 and later.
Benefits under the SERP are reduced, dollar-for-dollar, by benefits received
under the Retirement and Restoration Plans, described above, and any social
security benefits. Current participants in the SERP are Messrs. Evans and
McClane. At current salary levels, at age 60, Mr. Evans would receive $70,000
annually and Mr. McClane would receive $64,000 annually.

  Agreements
 
     Cullen/Frost has change-in-control agreements with two of the four named
executives, Messrs. Evans and Green, above and other key employees. The main
purposes of these agreements are (i) to help executives evaluate objectively
whether a potential change-in-control is in the best interests of shareholders,
(ii) to help protect against the departure of executives, thus assuring
continuity of management, in the event of an actual or threatened merger or
change-in-control, and (iii) to maintain compensation and benefits comparable to
those available from competing employers. "Change-in-control" is defined as an
acquisition of 20 percent or more of Cullen/Frost Common Stock by an individual,
corporation, partnership, group, association or other person; certain changes in
the composition of the Board of Directors by 50 percent or more; or certain
changes in control which must be reported to the Securities and Exchange
Commission.
 
     Messrs. Evans and Green could receive 2.99 times their average annual
compensation during the previous five years if their position is terminated
within two years following the change-in-control either by Cullen/Frost, if the
termination is for reasons other than cause, disability or retirement, or either
if he terminates his employment for good reason. "Good reason" is defined as a
significant reduction or change in responsibility, involuntary transfer to a new
location, a reduction in compensation or benefits, the failure of any successor
to Cullen/Frost to assent to such change-in-control agreement, any purported
termination by Cullen/Frost of the covered person without providing such person
a proper written notice of termination or, in the case of the two executives,
their good faith determination, within 90 days of a change-in-control, that as a
result of the change-in-control they are not able to discharge their duties
effectively. The agreements also provide for a continuation of certain employee
benefits for qualifying executives upon a change-in-control.
 
     Assuming that a change-in-control of Cullen/Frost had occurred effective
December 31, 1996 and that termination of employment also had occurred on that
date, the maximum amounts that could be payable to the named executives are: Mr.
Evans $1,524,128; and Mr. Green $717,373.
 
     The Company has entered into an agreement with Mr. McClane in connection
with his planned retirement from the Company on June 1, 1999 that provides for
his employment as President of the Company through the 1997 Annual Meeting of
Stockholders, his being employed as a consultant with the Company thereafter
until May 31, 1999 and his continuing to be considered for nomination and
reelection to the Board of Directors of the Company until such time as he
reaches age 70. The agreement provides for a salary of $25,000 per month through
the term of the agreement, a $90,000 bonus payable by March 31, 1997 and certain
medical, health, life, disability and other benefits similar to those provided
to other members of senior management. The agreement also provides for the
cancellation of 12,800 stock options previously granted Mr. McClane that would
not otherwise vest until after his retirement and the grant of an additional
15,000 stock options at an exercise price of $27.25 per share which vest on May
31, 1999. The agreement may be terminated for cause and provides for continued
payments in the event of disability.

(1) On December 31, 1996, Cullen/Frost owned no securities of Cullen/Frost for
    its own account. However, The Frost National Bank and United States National
    Bank of Galveston held of record in various fiduciary capacities an
    aggregate of 2,211,173 shares. The Frost National Bank and United States
    National Bank of Galveston had sole voting power for 1,646,798 shares and
    132,126 shares, respectively. United States National Bank of Galveston had
    shared voting power for 2,984 shares. The Frost National Bank and United
    States National Bank of Galveston had sole investment power for 175,844
    shares and 133,126 shares, respectively, and shared investment power for
    25,328 shares and 3,984 shares, respectively. The Frost National Bank and
    United States National Bank of Galveston had both sole voting and investment
    power for 154,359 shares and 130,686 shares, respectively. All of the shares
    are held by Cullen/Frost subsidiary banks, each of which has reported that
    the securities, registered in its name as fiduciary or in the names of
    various of its nominees, are owned by many separate accounts, each of which
    is governed by a separate instrument which sets forth the powers of the
    fiduciary with regard to the securities held.
 
                    TRANSACTIONS WITH MANAGEMENT AND OTHERS
 
     Since January 1, 1996, some of the executive officers and directors of
Cullen/Frost, and some of their associates, are and have been customers of one
or more of the Cullen/Frost subsidiary banks and have had transactions with
these banks in the ordinary course of business. Other transactions have
included, in addition to borrowings from the subsidiary banks, the following:
 
          1. Cullen/Frost and some of its subsidiaries have policies of
     insurance written through Catto & Catto, an insurance agency of which Mr.
     Catto and Mr. Hayne, Cullen/Frost directors, are partners. Fees paid by
     Cullen/Frost and its subsidiaries aggregated less than five percent of the
     total gross revenues of Catto & Catto for its fiscal year ended December
     31, 1996.
 
          2. Mr. Eugene Dawson, Sr., owns 28.35% of Jesse A. Baker Investments,
     Inc. (JAB). JAB has a $600,000 line of credit with The Frost National Bank.
     During 1996, JAB had draws of $610,000 and repayments of $899,863. The
     balance of the line at December 31, 1996 was $375,000. In addition, JAB has
     a loan for land development purposes. Principal payments on this loan
     totaled $165,200 and interest payments totaled $67,110 during 1996. The
     balance of the loan at December 31, 1996 was $825,000. The principal and
     interest payments required by the terms of the Notes for 1997 are
     anticipated to exceed 5% of JAB's gross revenues.
 
     All of the foregoing transactions were on substantially the same terms,
including interest rates and collateral to the extent applicable, as those
prevailing at the time for comparable transactions with other persons and did
not involve more than normal risk of collectibility or present other unfavorable
features. Additional transactions in the future may be expected to take place
with the subsidiary banks in the ordinary course of business.

     Also, a loan originally established in the ordinary course of business with
a subsidiary bank and related to a director, Mr. Vaughan, had subsequently been
reclassified as other assets. The debt was satisfied in full on May 17, 1996.
This transaction is described on page 9, "Compensation and Benefits Committee
Interlocks and Insider Participation in Compensation Decisions."
 
     In the opinion of management, all of the above described transactions were
effected on terms comparable to those available to unaffiliated parties.
 
             PROPOSED RESOLUTION TO AMEND ARTICLES OF INCORPORATION
                             (ITEM 2 ON PROXY CARD)
 
     Cullen/Frost is presently authorized under its Articles of Incorporation to
issue not more than 30,000,000 shares of Common Stock, par value $5 per share.
As of April 4, 1997, there were 22,507,928 of shares of Common Stock outstanding
and 1,795,826 shares of Common Stock reserved for issue under various employee
benefit plans.
 
     The Board of Directors has proposed, and there will be submitted to a vote
of the shareholders at the meeting, a resolution to amend the Articles of
Incorporation to increase the authorized shares of Common Stock, par value $5
per share, from 30,000,000 to 60,000,000 shares. Authorized shares of Common
Stock may be issued on such terms and for such corporate purposes as the Board
of Directors may determine, and without further action by the shareholders
unless such action is required by applicable law or by the rules of any stock
exchange or securities quotation system on which the Common stock may then be
listed or quoted. As a condition to the Common Stock's designation and quotation
as a National Market System security by the National Association of Securities
Dealers, certain issuance's of Common Stock require prior shareholder approval,
including issuances in connection with new stock option plans and certain
issuance's of 20% or more of the Common Stock outstanding (before the issuance's
of such shares).
 
     The text of the proposed resolution is as follows:
 
          RESOLVED, that Article Four of Cullen/Frost's Articles of
     Incorporation be amended to increase the aggregate number of shares of
     Common Stock, par value $5 per share, the Company has authority to issue to
     60,000,000.
 
     The Board of Directors believes that it is important to have the additional
shares of Common stock available for issuance as and when needed in order to
avoid the delay and expense incident to obtaining shareholder approval at a
later date or dates and to provide Cullen/Frost greater flexibility in the
consideration of future stock dividends or stock splits, sales of Common Stock
or convertible securities to enhance capital and liquidity, possible future
acquisitions and other corporate purposes. As of the date hereof, Cullen/Frost
has no specific plan to utilize the remaining or the proposed new authorized
shares.
 
     A potential effect of the proposed increase in the authorized Common Stock
could be a dilution of present shareholders' interest in Cullen/Frost if it
issues additional shares. In addition, any issuance of additional shares of
Common Stock could have the effect of diluting the earnings per share and book
value per share of existing shares of Common Stock.
 
     The Board of Directors has not proposed the increase in authorized shares
of Common Stock with the intention of using such shares for anti-takeover
purposes although the availability of such shares (either alone or with the
attached Preferred Stock purchase rights) may theoretically be utilized to
render more difficult or discourage an attempt to acquire control of
Cullen/Frost.
 
     Holders of Common Stock have one vote per share, may not cumulate votes in
the election of directors and have no preemptive rights to subscribe for or
purchase from Cullen/Frost any additional shares of
 
- --------------------------------------------------------------------------------
 
                                       17
<PAGE>   20
 
- --------------------------------------------------------------------------------
 
Common stock. Holders of Common Stock do not have any dissenters' or appraisal
rights in connection with this proposal.
 
     The affirmative vote of the holders of two-thirds of all of the outstanding
shares of Common Stock entitled to vote thereon is required to approve the
proposed amendment to the Company's Articles. The Board of Directors recommends
that shareholders vote "FOR" the amendment. Proxies, unless indicated to the
contrary, will be voted "FOR" the amendment.
 
                APPROVAL OF THE AMENDMENT TO THE 1992 STOCK PLAN
                             (ITEM 3 ON PROXY CARD)
 
     In 1992, the shareholders approved the establishment of the Cullen/Frost
Bankers, Inc., 1992 Stock Plan. The complete text of the 1992 Stock Plan is
attached as Annex A. The Plan's purpose is to enable Cullen/Frost and its
affiliates to retain and motivate key employees and to encourage their ownership
of Cullen/Frost stock, providing them a way to acquire or increase a proprietary
interest in the Company's success.
 
     The Board of Directors believes the Plan is a key element of Cullen/Frost's
executive compensation program because stock-based incentive compensation ties
executive compensation directly to stock value. As a result of recent regulatory
changes, it has become necessary to take certain steps in order to preserve the
deductibility of certain compensation paid by Cullen/Frost. In order to address
these recent regulatory changes and to enhance flexibility under the Plan, the
Board of Directors has unanimously approved, subject to shareholder approval, an
amendment to the 1992 Stock Plan (the "Amendment"). The complete text of the
Amendment is attached as Annex B.
 
     Four types of incentives may be granted under the Plan -- restricted stock,
incentive stock options, nonqualified stock options, and/or stock appreciation
rights. Each type of incentive is more fully described below. Shares granted
under the Plan may be authorized but unissued shares or previously issued shares
reacquired by Cullen/Frost, including shares purchased on the open market and
not reserved for any other purposes.
 
     The Board of Director's Compensation and Benefits Committee, composed of
five outside directors and one outside advisory director, administer the Plan,
select participants, and determine the type, number, and conditions of incentive
awards. Eligible employees are those who, in the Committee's opinion, are
materially responsible for the management, growth, and protection of significant
parts of the business or functions of the Company and/or its subsidiaries or
affiliates. Since the Plan contemplates grants to future as well as present
employees, Cullen/Frost cannot currently predict the total number of
participants.
 
SUMMARY DESCRIPTION OF THE AMENDMENT TO THE 1992 STOCK PLAN
 
     The following summarizes the material terms of the Amendment to the 1992
Stock Plan. If adopted by shareholders, the Amendment will be effective as of
May 28, 1997.
 
INCREASE IN SHARE AUTHORIZATION
 
     The Plan currently authorizes 1,760,000 shares for issuance, of which
410,222 shares remain available for grant. In order to ensure that there will be
sufficient shares available for grant under the Plan in future years, the
Amendment increases the total number of shares of Common Stock authorized for
issuance under the Plan by 1,100,000 shares. Of the 2,860,000 total shares
authorized under the Plan pursuant to the Amendment, no more than 265,000 shares
may be granted in the form of restricted stock.

<PAGE>   21
 
- --------------------------------------------------------------------------------
 
INDIVIDUAL AWARD LIMIT
 
     In order to exempt future awards from the tax deductibility limitations of
Internal Revenue Code Section 162(m), the Amendment to the 1992 Stock Plan
provides that no more than four hundred thousand (400,000) shares under Options
and no more than four hundred thousand (400,000) shares in the form of stock
appreciation rights may be granted to any Participant in any one fiscal year and
that no more than one hundred fifty thousand (150,000) shares will be paid out
under any Restricted Stock award in any one fiscal year, to any Participant.
This Amendment is not intended to increase future award sizes or otherwise alter
the Compensation and Benefits Committee's (the "Committee's") general practices
in determining award sizes.
 
PERFORMANCE MEASURES
 
     The Performance Measures on which awards qualifying for an exemption under
Section 162(m) are based shall be chosen from among the following: return on
equity, earnings per share, operating cash flow, gross revenue, income before
taxes, net income, return on revenue, and stock price appreciation. This
provision will allow the Committee flexibility in establishing performance goals
while maintaining an exemption to the tax deductibility limitations imposed by
Section 162(m).
 
TRANSFERABILITY OF NONQUALIFIED STOCK OPTIONS
 
     As a result of recent revisions to Section 16 of the Securities Exchange
Act of 1934 and in order to enhance flexibility in the design of nonqualified
stock options under the Plan, the Amendment permits the transferability of
nonqualified stock options in the Committee's discretion.
 
POOLING OF INTERESTS
 
     Certain actions with respect to equity-based compensation can prevent a
company from utilizing pooling of interests accounting in connection with
business combinations. In order to preserve Cullen/Frost's ability to use
pooling of interests accounting, the Amendment contains a provision which
permits the Board of Directors to take any action necessary with respect to the
Plan in order to preserve Cullen/Frost's ability to use pooling of interests
accounting.
 
SUMMARY DESCRIPTION OF THE EXISTING PLAN
 
     Restricted Stock:  When it awards restricted stock, the Committee will have
established a restriction period during which shares awarded may not be sold,
exchanged, transferred, pledged, or otherwise encumbered by the participant;
however, during the restriction period, the participant shall generally have all
shareholder rights including voting, dividends and other distributions.
 
     Incentive and Nonqualified Stock Options:  The purchase price of stock
issued under both types of stock options will be determined by the Committee,
but will not be less than the fair market value of Common Stock subject to the
option at the time the option is granted. Incentive Stock Options will not be
transferable other than by will or laws of descent and distribution. As provided
in the Amendment, Nonqualified Stock Options generally will not be transferable
other than by will or laws of descent and distribution except as may be
permitted at the discretion of the Committee. As provided in current plans, the
Board of Directors may, upon recommendation of the Committee and to carry out
purposes of this plan, amend options to reduce the exercise price and number of
shares.
 
     Stock Appreciation rights (SARs):  The Committee may grant SARs either in
tandem with stock options or freestanding and unrelated to options. In either
case, the form of payment of a SAR will be determined by the Committee either at
grant time or when exercised, and may be in shares of Common Stock, cash, or a
combination of the two: (i) if granted other than in tandem, the Committee will
determine the
 
- --------------------------------------------------------------------------------
 
                                       19
<PAGE>   22
 
- --------------------------------------------------------------------------------
 
number of shares of Common Stock covered by and the exercise period for the SAR.
Upon exercise of the SAR, the participant will receive an amount equal to the
excess of the fair market value of one share of stock on the date the exercise
is received by the Company over the fair market value of one share of the stock
on the grant date, multiplied by the number of shares of stock covered by the
SAR; (ii) if granted in tandem with an option, a SAR may be awarded when the
option is granted or any time thereafter, the Committee may limit the exercise
period of the SAR except that the SAR's exercise period may not exceed that of
the option. The participant may exercise the SAR when the option is exercisable,
surrender the option, and receive on exercise an amount equal to the excess of
fair market value of one share of stock on the date the election to surrender is
received by the Company over the option purchase price, multiplied by the number
of shares of stock covered by the surrender option.
 
FEDERAL INCOME TAX CONSEQUENCES OF THE 1992 STOCK PLAN
 
     Federal Tax Treatment of Incentive Stock Options:  A participant will not
realize taxable income when an incentive stock option is granted under the 1992
Plan or when an incentive stock option is exercised, and the Company will not be
entitled to a deduction with respect to the granting of exercise of such an
option except in the limited circumstances discussed below. If an incentive
stock option grantee holds the shares acquired under the option for at least two
years from the date the option is granted and at least one year from the date
the option is exercised, any gain realized by the participant when the shares
are sold will be taxable to the grantee as capital gain. If the shares are not
held for the two- and the one-year periods, the participant will realize
ordinary income in the year of disposition of the shares in an amount equal to
the excess of the fair market value of the shares on the date of exercise (or
the proceeds of the disposition, if lower) over the option exercise price, and
the Company will be entitled to a corresponding deduction. Any remaining gain
will generally be capital gain. If the shares are disposed of at a loss, the
loss will be a capital loss. The difference between the exercise price of an
incentive stock option and the fair market value of the shares subject to the
option at the time of exercise is an item of tax preference which may result in
the participant being subject to the alternative minimum tax. Whether a
participant is subject to the alternative minimum tax in lieu of "regular"
income tax will depend on individual facts and circumstances.
 
     Federal Tax Treatment of Nonqualified Stock Options:  A participant will
not realize taxable income, and the Company will not be entitled to a deduction,
at the time that a nonqualified stock option is granted under the 1992 Plan.
Upon exercising a nonqualified stock option, a participant will realize ordinary
income, and the Company will be entitled to a corresponding deduction, in an
amount equal to the excess of the fair market value on the exercise date of the
shares subject to the option over the exercise price of the option. The
participant will have a basis in the shares received as a result of the
exercise, for purposes of computing capital gain or loss on a future sale or
exchange of those shares, equal to the fair market value of those shares on the
exercise date.
 
     Federal Tax Treatment of Restricted Stock:  The recipient of a grant of
restricted stock under the 1992 Plan will not realize taxable income and the
Company will not be entitled to a deduction with respect to such grant on the
date of such grant unless the recipient makes an election under Section 83(b) of
the Code, within 30 days after grant, to include in income the fair market value
of the stock on the date of grant. When the participant becomes entitled to
freely transfer the stock, the grantee will realize ordinary income in an amount
equal to the excess of the fair market value of the stock on such date over the
amount, if any, that the recipient paid for the stock and the Company will
generally be entitled to a corresponding deduction.
 
     Federal Tax Treatment of SARs:  The recipient of a grant of SARs will not
realize taxable income and the Company will not be entitled to deduction with
respect to such grant on the date of such grant. Upon the exercise of a SAR, the
recipient will realize ordinary income, and the Company will be entitled to a
corresponding deduction, equal to the amount of cash received.

     The 1992 Stock Plan shall terminate not later than 10 years after its
original approval by the Board of Directors, and the board has the power to
terminate it at any earlier time.
 
     The benefits that will be received under the 1992 Stock Plan, as amended,
by particular individuals or groups are not determinable at this time. The
benefits that were received for the 1996 fiscal year by the Named Executive
Officers pursuant to the 1992 Stock Plan are summarized in tables on page 11.
 
     The accompanying proxy will be voted in favor of approval of the Amendments
unless contrary instructions are noted on the proxy.
 
     The affirmative vote of a majority of the shares of Common Stock present in
person or by proxy are entitled to vote at the Annual Meeting is required for
adoption of the Amendment to the Plan.
 
     The Board of Directors recommends a vote "FOR" approval of the Amendment.
 
                   APPROVAL OF THE 1997 DIRECTORS STOCK PLAN
                             (ITEM 4 ON PROXY CARD)
 
     On January 28, 1997, the Company's Board of Directors (the "Board")
adopted, subject to approval by the shareholders, the 1997 Directors Stock Plan
(the "Plan") for nonemployee directors. The purpose of the Plan is to further
align the interests of the nonemployee directors and shareholders by encouraging
director stock ownership and motivating directors with compensation tied to the
value of the Company's Common stock. The Plan will also enhance the Company's
ability to attract and retain the services of experienced and highly qualified
nonemployee directors.
 
     The affirmative vote of a majority of the shares of Common Stock present in
person or by proxy and entitled to vote at the Annual Meeting is required for
adoption of the Plan.
 
     The Board of Directors recommends that shareholders vote "FOR" this
proposal.
 
SUMMARY DESCRIPTION OF THE STOCK PLAN
 
     The following is a summary of the principal features of the Plan, a copy of
which is set forth hereto as Annex C. If approved by the shareholders, the Plan
will be effective as of May 28, 1997.
 
     Administration.  The Plan will be administered by the Compensation and
Benefits Committee of the Board (the "Committee").
 
     Participation.  Nonemployee directors shall participate in the Plan.
Fifteen of the eighteen current directors are nonemployees and shall participate
in the Plan.
 
     Stock Available for Issuance Through the Plan.  The Plan provides for
awards of nonqualified stock options, as further described below. Up to 150,000
shares of the Company's Common Stock are authorized for issuance through the
Plan.
 
     Description of Awards Under the Plan.  The Committee may award to
nonemployee directors nonqualified stock options. Stock options will typically
be issued in consideration for the performance of services for the Company.
Awards of nonqualified stock options are described in greater detail below.
 
     The Committee will have discretion to award nonqualified stock options
("NQSOs"). The maximum grant of NQSOs in any one fiscal year under the Plan to
any one Outside Director is 5,000 shares. The Plan provides that the exercise
price of any NQSO may not be less than the fair market value of the underlying
shares of Common Stock on the date of grant. Upon the exercise of an NQSO
granted under the Plan, the option price is payable in full to the Company,
either in cash or by tendering shares having a fair market value
 
- --------------------------------------------------------------------------------
 
                                       21
<PAGE>   24
 
- --------------------------------------------------------------------------------
 
at the time of exercise equal to the total option price (providing shares have
been held for at least six months prior to their tender). NQSOs granted to
nonemployee directors under the Plan will expire at such times as the Committee
determines at the time of grant. In no event should the exercise period exceed a
maximum of ten years. Each NQSO award agreement will set forth the extent to
which the director will have the right to exercise the option following
termination of the director's service to the Company.
 
     The following discussion is intended only as a brief summary of the federal
income tax rules relevant to the Company and to nonemployee directors for NQSO
awards under the Plan.
 
     A director will recognize no income upon the grant of an NQSO, and, upon
exercise, will recognize ordinary income to the extent of the excess of the fair
market value of the shares on the date the option is exercised over the amount
paid by the director for the shares. Upon a subsequent disposition of the shares
received under the option, the director will recognize capital gain or loss to
the extent of the difference between the fair market value of the shares at the
time of exercise and the amount realized on the disposition.
 
     The Company will receive an income tax deduction at the same time and in
the same amount which is taxable to the director as compensation. The ordinary
income a nonemployee director recognizes under the foregoing rules is not
subject to withholding. However, a nonemployee director must take such income
into account in determining the tax payments such director is required to make.
 
     On April 4, 1997, the closing price for a share of the Company's Common
Stock, as reported on the National Association of Security Dealers Automated
Quotation system composite tape, was 35.00.
 
     Adjustments and Amendments.  The Plan provides for appropriate adjustments
in the number of shares of Common stock available for future awards in the event
of changes in outstanding Common Stock by reason of a merger, stock split, or
certain other events.
 
     The Plan may be modified or amended by the Committee at any time and for
any purpose which the Committee deems appropriate. However, no such amendment
shall adversely affect any outstanding awards without the affected holder's
consent.
 
     Nontransferability.  Unless otherwise provided in an award agreement, no
award granted pursuant to, and no right to payment under, the Plan shall be
assignable or transferable by a nonemployee director except by will or by the

                             SELECTION OF AUDITORS
                             (ITEM 5 ON PROXY CARD)
 
     The Board of Directors desires to obtain from the shareholders an
indication of their approval of the selection of Ernst & Young LLP, certified
public accountants, as independent auditors of Cullen/Frost. Accordingly, upon
the affirmative vote of a majority of the shares of Cullen/Frost Common Stock
present at the meeting, the Board of Directors will adopt a resolution naming
Ernst & Young LLP as independent auditors of Cullen/Frost for the fiscal year
which commenced January 1, 1997. Ernst & Young LLP has audited the financial
statements of Cullen/Frost since 1969.
 
     In the opinion of Cullen/Frost management, the presence of Ernst & Young
LLP at the meeting is not necessary to present properly the results of
operations of Cullen/Frost. However, if any shareholder desires to submit a
question to the independent auditors, management will ensure that the question
is transmitted to them and that an appropriate response is made directly to the
shareholder.
 
                             SHAREHOLDER PROPOSALS
 
     With respect to the 1998 Annual Meeting of Shareholders, any shareholder's
proposal for inclusion in the Proxy Statement for that meeting must be received
by Cullen/Frost at its principal offices not later than December 28, 1997.
 
                                 OTHER MATTERS
 
     Management of Cullen/Frost knows of no other business to be presented at
the meeting, but if other matters do properly come before the meeting, unless
otherwise instructed, it is intended that the persons named in the proxy will
vote shares according to their best judgment.
 
                                          By Order of the Board of Directors

the Board of Directors shall determine that, in order to carry out the purposes
of the Plan, it is necessary or desirable to reduce the purchase price of Stock
issued under any Option, then the Board of Directors may amend any Option (i) to
reduce the exercise price, provided that in no case shall such exercise price be
reduced below the fair market value (as determined by the Committee) of the

provided, that no such reduction shall be made without consent of the Optionee.
 
     7.3. OPTION PRICE; MEDIUM OF PAYMENT.  The purchase price of Stock issued

such purchase price shall be made in cash or, if provided in the Option
Agreement, payment of such purchase price may be in shares of Stock which have
been held by the Participant for more than six months, or any combination of
both cash and shares of Stock; in such case, shares of Stock delivered to the
Company as payment for Stock issued upon exercise of an Option shall be valued
at their fair market value (as determined by the Committee) or their par value,
if higher.

entity), thereafter upon any exercise of a Stock Option theretofore granted the
optionee shall be entitled to purchase under such Stock Option, in lieu of the
number of shares of Stock as to which such Stock Option would be exercisable,
the number and class of shares of stock and securities to which the Participant
would have been entitled pursuant to the terms of the agreement of merger or
consolidation if, immediately prior to such merger or consolidation, the
Participant had been the holder of record of the number of shares of Stock as to
which such Stock Option would be exercisable. If the Company shall not be the
surviving corporation in any merger or consolidation or shall survive only as a
wholly-owned subsidiary of another corporation or other entity, or if the
Company is to be dissolved or liquidated, then unless the surviving corporation
(or the parent corporation or other entity if the Company shall survive only as
a subsidiary) assumes or substitutes new options for all Stock Options then
outstanding, (i) the time at which all Stock Options then outstanding, may be
exercised shall be accelerated and all such Stock Options shall become
exercisable in full on or before a date fixed by the Company prior to the
effective date such merger or consolidation or such dissolution or liquidation,
and (ii) upon such effective date any unexercised Stock Options shall expire.
 
     7.6. CHANGE IN CONTROL.  Any Option Agreement may provide that if at any
time there shall occur a Change in Control, then the time at which the Stock
Option evidenced thereby may be exercised shall be accelerated and the Stock
Option shall immediately become exercisable in full.
 
SECTION 8. STOCK APPRECIATION RIGHTS
 
     8.1. GRANT OF STOCK APPRECIATION RIGHT.  The Committee may, in its
discretion, grant Stock Appreciation Rights in tandem with a Stock Option, in

Option, the Committee shall determine the number of shares of Stock covered by
such Stock Appreciation Right. Stock Appreciation Rights shall be subject to the
following terms and conditions and such other terms and conditions as the
Committee may prescribe.
 
     8.2. TIME AND PERIOD OF GRANT.  If a Stock Appreciation Right is granted
with respect to a Stock Option, it may be granted at the time of the grant of
the Stock Option or at any time thereafter. If a Stock Appreciation Right is
granted in tandem with any Stock Option at the time the Stock Appreciation Right
is granted the Committee may limit the exercise period for such Stock
Appreciation Right. In no event shall the exercise period for a Stock
Appreciation Right in tandem with any Stock Option exceed the exercise period
for such Stock Option. If a Stock Appreciation Right is granted without being
related to an underlying Stock Option, the period for exercise of the Stock
Appreciation Right shall be set by the Committee at the time of grant.
 
     8.3. VALUE OF STOCK APPRECIATION RIGHT.  If a Stock Appreciation Right is
granted in tandem with a Stock Option, the Participant will be entitled to
surrender the Stock Option at any time such Stock Option is exercisable and
receive in exchange therefor an amount equal to (i) the excess of the fair
market value of one share of the Stock on the date the election to surrender is
received by the Company over the Stock Option purchase price, multiplied by (ii)
the number of shares of Stock covered by the Stock Option which is surrendered.
If a Stock Appreciation Right is granted otherwise than in tandem with a Stock
Option, the Participant will receive upon exercise of the Stock Appreciation
Right an amount equal to (i) the excess of the fair market value of one share of
the Stock on the date the election to exercise such Stock Appreciation Right is
received by the Company over the fair market value of one share of the Stock on
the date of grant, multiplied by (ii) the number of shares of Stock covered by
the Stock Appreciation Right.
 
     8.4. PAYMENT OF STOCK APPRECIATION RIGHT.  Payment of a Stock Appreciation
Right shall be in the form of shares of Common Stock, cash, or any combination
of shares and cash. The form of payment upon exercise of such a right shall be
determined by the Committee either at the time of grant of the Stock
Appreciation Right or at the time of exercise of the Stock Appreciation Right.

     8.5. CHANGE IN CONTROL.  Any Stock Appreciation Right may provide that if
at any time there shall occur a Change in Control, then the time at which the
Stock Appreciation Right may be exercised shall be accelerated and the Stock
Appreciation Right shall immediately become exercisable in full.
 
SECTION 9. MISCELLANEOUS
 
     9.1. NO RIGHT TO EMPLOYMENT.  Nothing in the Plan or in the terms of any
Incentive granted under the Plan shall in any manner be construed to limit or
restrict in any way the right of the Company or its subsidiaries or affiliates
to terminate any Participant's employment at any time and without regard to the
effect of such termination on the Participant under the Plan, nor confer upon
any Participant any right to continue in the employ of the Company or its
subsidiaries or affiliates.
 
     9.2. TAX WITHHOLDING.  The Company shall have the right to deduct from all
payments any Federal, state, or local taxes required by law to be withheld with
respect to such payments, and the Participant or other person receiving shares
of Stock pursuant to the Plan may be required to pay the Company, as
appropriate, the amount of any such taxes which the Company is required to
withhold with respect to such Stock. A Participant may elect, subject to the
approval of the Committee, to have a portion of the shares of Stock which would
otherwise be transferred to the Participant under the Plan withheld by the
Company to satisfy the tax withholding requirement of this Section.
 
     9.3. GOVERNING LAW.  The Plan, and all agreements and other documents
delivered hereunder, shall be construed in accordance with and governed by the

borne by the Company.
 
     9.5. AMENDMENT OR TERMINATION OF THE PLAN.  The Board of Directors in its
discretion may amend or terminate the Plan at any time; provided, that no
amendment or termination that shall affect any Incentive theretofore granted may
be made which would impair the rights of the Participant without the consent of
such Participant; and provided, further, that the Board of Directors may not
make any amendment without the approval of the shareholders of the Company if
such approval is necessary in order for the Plan to continue to comply with Rule
16b-3 under the Securities Exchange Act of 1934.
 
     9.6. DURATION OF THE PLAN.  Subject to the Board's right to earlier
terminate the Plan pursuant to Section 9.5 hereof, the Plan shall terminate not

granted prior to termination of the Plan.

         be granted in the form of Stock Appreciation Rights, pursuant to any
         Incentives granted in any one fiscal year to any one single
         Participant, shall be four hundred thousand (400,000)
 
     (c) Restricted Stock:  The maximum aggregate grant with respect to
         Incentives granted in the form of Restricted Stock granted in any one
         fiscal year to any one participant shall be one hundred fifty thousand
         (150,000) shares of common stock.
 
Section 5.4 shall be added to the Plan and shall read as follows:
 
     5.4 PERFORMANCE MEASURES.  Unless and until the Committee proposes for
shareholder vote and shareholders approve a change in the general performance
measures set forth in this Section 5.4, the attainment of which may determine
the degree of payout and/or vesting with respect to Incentives granted to
Covered Employees which are designed to qualify for the Performance-Based
Exception, the performance measure(s) to be used for purposes of such grants
shall be chosen from among:
 
     (a) Return on Equity;
 
     (b) Earnings Per Share;
 
     (c) Operating Cash Flow;

- --------------------------------------------------------------------------------
 
     (d) Gross Revenue;
 
     (e) Income Before Taxes;
 
     (f) Net Income;
 
     (g) Return on Revenue; and
 
     (h) Stock Price Appreciation.
 
     The Committee shall have the discretion to adjust the determinations of the
degree of attainment of the preestablished performance goals, provided, however,
that Incentives which are designed to qualify for the Performance-Based
Exception, and which are held by Covered Employees, may not be adjusted upward
(the Committee shall retain the discretion to adjust such Incentives downward).
 
     In the event that applicable tax and/or securities laws change to permit
Board discretion to alter the governing performance measures without obtaining
shareholder approval of such changes, the Board shall have sole discretion to
make such changes without obtaining shareholder approval. In addition, in the
event that the Committee determines that it is advisable to grant Incentives
which shall not qualify for the Performance-Based Exception, the Committee may
make such grants without satisfying the requirements of Code Section 162(m).
 
The second sentence of Section 7.2 of the Plan shall be deleted and replaced
with the following:
 
     Each Incentive Stock Option and all rights granted thereunder shall not be
transferable other than by will or the laws of descent and distribution, and
shall be exercisable during the optionee's lifetime only by the optionee or his
guardian or legal representative. Except as may be otherwise provided by the
Committee, each Nonqualified Stock Option and all rights granted thereunder
shall not be transferable other than by will or the laws of descent and
distribution, and shall be exercisable during the optionee's lifetime only by
the optionee or his guardian or legal representative.
 
Section 9.7 shall be added to the Plan and shall read as follows:
 
     9.7 POOLING OF INTERESTS ACCOUNTING.  Notwithstanding any other provision
of the Plan to the contrary, in the event that the consummation of a Change in
Control is contingent on using the pooling of interests accounting methodology,
the Board may take any action necessary to preserve the use of pooling of
interests accounting.
 
Section 9.8 shall be added to the Plan and shall read as follows:
 
     9.8 COMPLIANCE WITH CODE SECTION 162(m).  At all times when Code Section
162(m) is applicable, all Incentives granted under this Plan shall comply with
the requirements of Code Section 162(m); provided, however, that in the event
the Board determines that such compliance is not desired with respect to any
Incentive or Incentives available for grant under the Plan, then compliance with
Code Section 162(m) will not be required. In addition, in the event that changes
are made to Code Section 162(m) to permit greater flexibility with respect to
any Incentive or Incentives available under the Plan, the Board may make any
adjustments it deems appropriate.

                                       C-2

- --------------------------------------------------------------------------------
 
Section 4.1, and in the number and class of and/or price of Shares subject to
outstanding Awards granted under the Plan, as may be determined to be
appropriate and equitable by the Committee, in its sole discretion, to prevent
dilution or enlargement of rights; provided, however, that the number of Shares
subject to any Award shall always be a whole number.
 
ARTICLE 5. NONQUALIFIED STOCK OPTIONS
 
     5.1. AWARD OF NQSOS.  Subject to the terms and provisions of the Plan,
NQSOs may be awarded to Outside Directors in such number, and upon such terms,
and at any time and from time to time as shall be determined by the Committee.
 
     5.2. AWARD AGREEMENT.  Each NQSO Award shall be evidenced by an Award
Agreement that shall specify the Option Price, the duration of the Option, the
number of Shares to which the Option pertains, and such other provisions as the
Committee shall determine.

Plan shall be at least equal to one hundred percent (100%) of the Fair Market
Value of a Share on the date the NQSO is granted.

expire at such time as the Committee shall determine at the time of grant.
 
     5.5. EXERCISE OF OPTIONS.  NQSOs granted under this Article 5 shall be
exercisable at such times and be subject to such restrictions and conditions as
the Committee shall in each instance approve, which need not be the same for
each grant or for each Outside Director. In no event should the exercise period
exceed a maximum of ten years.
 
     5.6. PAYMENT.  NQSOs granted under this Article 5 shall be exercised by the
delivery of a written notice of exercise to the Company, setting forth the
number of Shares with respect to which the NQSO is to be exercised, accompanied
by full payment for the Shares.
 
     The Option Price upon exercise of any NQSO shall be payable to the Company
in full either: (a) in cash or its equivalent, or (b) by tendering previously
acquired Shares having an aggregate Fair Market Value at the time of exercise
equal to the total Option Price (provided that the Shares which are tendered
must have been held by the Outside Director for at least six (6) months prior to
their tender to satisfy the Option Price), or (c) by a combination of (a) and
(b).
 
     The Committee also may allow cashless exercise as permitted under Federal
Reserve Board's Regulation T, subject to applicable securities law restrictions,
or by any other means which the Committee determines to be consistent with the
Plan's purpose and applicable law.
 
     Subject to any governing rules or regulations, as soon as practicable after
receipt of a written notification of exercise and full payment, the Company
shall deliver to the Outside Director, in the Outside Director's name, Share
certificates in an appropriate amount based upon the number of Shares purchased
under the NQSO.
 
     5.7. RESTRICTIONS ON SHARE TRANSFERABILITY.  The Committee may impose such
restrictions on any Shares acquired pursuant to the exercise of an NQSO granted
under this Article 5 as it may deem advisable, including, without limitation,
restrictions under applicable federal securities laws, under the requirements of

traded, and under any blue sky or state securities laws applicable to such
Shares.
 
     5.8. TERMINATION OF DIRECTORSHIP.  Each Outside Director's Award Agreement
shall set forth the extent to which the Outside Director shall have the right to
exercise the NQSO following termination of the Outside Director's directorship
with the Company. Such provisions shall be determined in the sole discretion of
the

- --------------------------------------------------------------------------------
 
Committee, shall be included in the Award Agreement entered into with each
Outside Director, need not be uniform among all NQSOs issued pursuant to this
Article 5, and may reflect distinctions based on the reasons for termination.
 
     5.9. NONTRANSFERABILITY OF NQSOS.  Except as otherwise provided by the
Committee, no NQSO granted under this Article 5 may be sold, transferred,
pledged, assigned, or otherwise alienated or hypothecated, other than by will or
by the laws of descent and distribution. Further, except as otherwise provided
in a Outside Director's Award Agreement, all NQSOs granted to a Outside Director
under this Article 5 shall be exercisable during his lifetime only by such
Outside Director.
 
ARTICLE 6. BENEFICIARY DESIGNATION
 
     Each Outside Director under the Plan may, from time to time, name any
beneficiary or beneficiaries (who may be named contingently or successively) to
whom any benefit under the Plan is to be paid in case of his or her death before
he or she receives any or all of such benefit. Each such designation shall
revoke all prior designations by the same Outside Director, shall be in a form
prescribed by the Company, and will be effective only when filed by the Outside
Director in writing with the Company during the Outside Director's lifetime. In
the absence of any such designation, benefits remaining unpaid at the Outside
Director's death shall be paid to the Outside Director's estate.
 
ARTICLE 7. RIGHTS OF DIRECTORS
 
     Nothing in the Plan shall interfere with or limit in any way the right of
the Company's shareholders to terminate any Outside Director's service at any
time, nor confer upon any Outside Director any right to continue in the service
of the Company.
 
ARTICLE 8. AMENDMENT, MODIFICATION, AND TERMINATION
 
     8.1. AMENDMENT, MODIFICATION, AND TERMINATION.  Subject to the terms of the
Plan, the Committee may at any time and from time to time, alter, amend, suspend
or terminate the Plan in whole or in part.
 
     8.2. ADJUSTMENT OF AWARDS UPON THE OCCURRENCE OF CERTAIN UNUSUAL OR
NONRECURRING EVENTS.  The Committee may make adjustments in the terms and
conditions of, and the criteria included in, Awards in recognition of unusual or
nonrecurring events (including, without limitation, the events described in
Section 4.2 hereof) affecting the Company or the financial statements of the
Company or of changes in applicable laws, regulations, or accounting principles,
whenever the Committee determines that such adjustments are appropriate in order
to prevent dilution or enlargement of the benefits or potential benefits
intended to be made available under the Plan.
 
     8.3. AWARDS PREVIOUSLY GRANTED.  Notwithstanding any other provision of the
Plan to the contrary, no termination, amendment, or modification of the Plan
shall adversely affect in any material way any Award previously granted under
the Plan, without the written consent of the Outside Director holding such
Award.
 
ARTICLE 9. INDEMNIFICATION
 
     Each person who is or shall have been a member of the Committee, or of the
Board, shall be indemnified and held harmless by the Company against and from
any loss, cost, liability, or expense that may be imposed upon or reasonably
incurred by him or her in connection with or resulting from any claim, action,
suit, or proceeding to which he or she may be a party or in which he or she may
be involved by reason of any action taken or failure to act under the Plan and
against and from any and all amounts paid by him or her in settlement thereof,
with the Company's approval, or paid by him or her in satisfaction of any
judgement in any such action, suit, or proceeding against him or her, provided
he or she shall give the Company an opportunity,

at its own expense, to handle and defend the same before he or she undertakes to
handle and defend it on his or her own behalf. The foregoing right of
indemnification shall not be exclusive of any other rights of indemnification to
which such persons may be entitled under the Company's Articles of Incorporation
or Bylaws, as a matter of law, or otherwise, or any power that the Company may
have to indemnify them or hold them harmless.
 
ARTICLE 10. SUCCESSORS
 
     All obligations of the Company under the Plan with respect to Awards
granted hereunder shall be binding on any successor to the Company, whether the
existence of such successor is the result of a direct or indirect purchase,
merger, consolidation, or otherwise, of all or substantially all of the business
and/or assets of the Company.
 
ARTICLE 11. LEGAL CONSTRUCTION
 
     11.1. GENDER AND NUMBER.  Except where otherwise indicated by the context,
any masculine term used herein also shall include the feminine; the plural shall
include the singular and the singular shall include the plural.
 
     11.2. SEVERABILITY.  In the event any provision of the Plan shall be held
illegal or invalid for any reason, the illegality or invalidity shall not affect
the remaining parts of the Plan, and the Plan shall be construed and enforced as
if the illegal or invalid provision had not been included.
 
     11.3. REQUIREMENTS OF LAW.  The granting of Awards and the issuance of

regulations, and to such approvals by any governmental agencies or national
securities exchanges as may be required.
