The Corporation's Annual Report to Shareholders for the year ended December 31,

on March 10, 2003. The Annual Report to Shareholders does not constitute a part
of the proxy soliciting material.

                               GENERAL INFORMATION

      The close of business on March 10, 2003, has been fixed as the record date
for determining the shareholders entitled to vote at the Annual Meeting of
Shareholders to be held on April 15, 2003.

      The Annual Meeting of Shareholders has been called for the purposes of (i)
electing directors of the Corporation for the coming year, (ii) ratifying the
appointment by the Board of Stovall, Grandey & Whatley as independent auditors
of the Corporation for its fiscal year ending December 31, 2003, and (iii)
transacting such other business as may properly come before the Annual Meeting
of Shareholders or any adjournment or adjournments thereof.

      Whether you can attend the meeting or not, your vote is important. Shares
can be voted at the meeting only if the owner is present or represented by
proxy. Accordingly, it is requested that you sign and return the enclosed proxy
in the envelope provided or you may electronically vote using the Internet or
you may vote by phone.

      Any person executing the accompanying proxy may revoke it at any time
prior to the actual voting thereof by filing with the Secretary of the
Corporation a written revocation thereof or a duly executed proxy bearing a
later date.


                                       1


      The cost of soliciting proxies will be borne by the Corporation. The
solicitation will be made by mail. The Corporation will also supply brokerage
firms and other custodians, nominees and fiduciaries with such number of proxy
materials as they may require for mailing to beneficial owners, and will
reimburse them for their reasonable expenses in connection therewith. Certain
directors, officers and employees of the Corporation, not specifically employed
for the purpose, may solicit proxies, without remuneration therefore, by mail,
telephone, telegraph or personal interview.

                      OUTSTANDING SHARES AND VOTING RIGHTS

      At the close of business on March 10, 2003, the record date for
determining the shareholders of the Corporation entitled to notice of and to
vote at the Annual Meeting of Shareholders, the Corporation had 6,179,017 shares
of common stock, $1.25 par value (the "Common Stock"), issued and outstanding.

      The presence, in person or by proxy duly authorized in writing, of the
holders of a majority of the issued and outstanding shares of Common Stock of
the Corporation is necessary to constitute a quorum at the Annual Meeting of
Shareholders.

      Each holder of shares of Common Stock will be entitled to one vote, in
person or by proxy, for each share of Common Stock of the Corporation owned of
record at the close of business on March 10, 2003. Cumulative voting for
directors is not permitted. Directors are elected by plurality vote and,
therefore, the ten (10) nominees receiving the highest number of affirmative
votes shall be elected as directors provided a quorum is present. The
affirmative vote of the holders of a majority of the shares of Common Stock of
the Corporation represented and voting at the annual meeting of shareholders on
the appointment of Stovall, Grandey & Whatley as independent auditors of the
Corporation is required to ratify that appointment.

      All shares represented at the Annual Meeting in person or by proxy shall
be counted in determining the presence of a quorum. Abstentions and broker
non-votes (shares held by a broker or nominee as to which a broker or nominee
indicates on the proxy that it does not have the authority, either express or
discretionary, to vote on a particular matter) are counted for the purpose of
determining the presence or absence of a quorum for the transaction of business
at the Annual Meeting but will not be considered part of the voting power
present with respect to any matter on which such shares are not voted.


                                       2


                                 PROPOSAL NO. 1:
                              ELECTION OF DIRECTORS

      The bylaws of the Corporation provide that the Board shall be comprised of
not more than twenty-five (25) members and that each director shall be elected
to serve until the next Annual Meeting of Shareholders and until his successor
shall be elected and shall qualify. Any vacancies on the Board may be filled by
a majority vote of the Board and any director so elected shall hold office for
the unexpired term of his predecessor or until the next election of directors by
the shareholders of the Corporation.

      The Board of Directors has set the number of directors at ten (10) and has
nominated the ten (10) persons named below for election to the Board of
Directors of the Corporation.

      Names of the nominees for directors and other information about them
appear in the following table. All of the nominees are now directors of the
Corporation and have consented to serve if elected. If for any unforeseen reason
a nominee is unable to serve if elected, the persons named in the accompanying
proxy may exercise their discretion to vote for a substitute nominee selected by
the Board. However, the Board has no reason to anticipate that any of the
nominees will not be able to serve, if elected.

                                PROPOSAL NO. 2:

                             AUDIT COMMITTEE REPORT

      Notwithstanding anything to the contrary set forth in any of the
Corporation's previous or future filings under the Securities Act of 1933 or the
Securities Exchange Act of 1934 that might incorporate this Proxy Statement or
future filings with the Securities and Exchange Commission, in whole or in part,
the following report shall not be deemed to be incorporated by reference into
any such filing.

      The Audit Committee of the Board of Directors consists of the five
directors whose names appear below. Each member of the Audit Committee is
"independent" as defined in Rule 4200 (a) (15) of the National Association of
Securities Dealers' listing standards.

      The Audit Committee's general role as a committee is to assist the Board
of Directors in overseeing the Corporation's financial reporting process and
related matters. Its specific responsibilities are set forth in its charter,
which is reviewed by the Audit Committee at least annually.

      The Audit Committee has reviewed and discussed with the Corporation's
management and Stovall, Grandey & Whatley, Certified Public Accountants, the
Corporation's independent auditors, the audited financial statements of the
Corporation contained in the Corporation's Annual Report to Shareholders for the
year ended December 31, 2002.

      The Audit Committee has also discussed with the Corporation's independent
auditors the matters required to be discussed pursuant to SAS 61 (Codification
of Statements on Auditing Standards, Communication with Audit Committees). The
Audit Committee has received and reviewed the written disclosures and the letter
from the independent auditors required by Independence Standards Board Standard
No. 1 (titled, "Independence Discussions with Audit Committees"), and has
discussed with the independent auditors such independent auditors' independence.
The Audit Committee has also considered whether the provision of non-audit
services to the Corporation by the independent auditor is compatible with
maintaining their independence.

      Based on the review and discussion referred to above, the Audit Committee
recommended to the Board of Directors that the audited financial statements be
included in the Corporation's Annual Report on Form 10-K for the fiscal year
ended December 31, 2002, filed with the Securities and Exchange Commission.

      This report is submitted on behalf of the Audit Committee.

                                 Robert L. Herchert, Chairman

401(k) Plan

      Effective December 1, 1997, the Corporation established a contributory
plan pursuant to Internal Revenue Code Section 401(k) covering substantially all
employees (the "401(k) Plan"). Each year the Corporation determines, at its
discretion, the amount, if any, of matching contributions. In 1997, 1998 and
1999, the Corporation did not make any matching contributions. For 2002, 2001
and 2000 the Board of Directors approved matching contributions of 100% of a
participants deferral of annual compensation up to and including 6% of annual
compensation. Also, the Board of Directors has approved the same matching
contributions for the year 2003. In 2002 the Corporation made contributions to
the corporation's 401(k) Plan on behalf of Mr. Norwood and Mr. Scott of $11,000
and $9,462 respectively

Supplemental Executive Retirement Plan

      Effective January 2002 the Board adopted a plan known as the Supplemental
Executive Retirement Plan ("SERP"). The purpose of the SERP is to attract and
retain employees of outstanding competence and to provide additional retirement
benefits for such employees. The SERP would provide benefits to a select group
of management employees, including the Corporation's Named Executive Officers
who contribute materially to the continued growth, development and future
business success of the Corporation. The SERP, and the individual agreements
established thereunder, are intended to be administered by the Compensation
Committee as unfunded welfare benefit plans established and maintained for the
participants.

      Under the SERP, the Corporation will purchase an insurance policy. The
policy is jointly owned by the Corporation and the participant with the policy
providing benefits to the participant in the amount and in the manner specified
by the participant's individual agreement. The Corporation shall make
contributions, as determined in its sole discretion, sufficient to fund the
premiums due under each policy. Over time, until the participant has reached
retirement, portions of the cash value of the policy will be vested to the
participant. However, the majority of the value will not accrue to the
participant until retirement.

      Should the participant's employment be terminated for any reason, other
than death, disability, or change of control of the Corporation before the
participant's fifth anniversary of employment all benefits under the SERP will
be forfeited. In the event of the participant's death at any time, the death
benefit of the participant's policy would be immediately paid to the
participant's beneficiary. In the event of disability of the participant or a
change of control of the Corporation at any time, the cash value of the
participant's policy would accrue to the participant.

      Should the participant's employment be terminated for any reason, other
than death, disability, change of control of the Corporation or cause (which is
defined in the plan), following the participant's fifth anniversary of
employment, the cash value of the policy will be credited to the participant
under the participant's policy upon the second anniversary of the participant's
termination of employment. The transfer of benefits after the two years
following termination is contingent on certain performance of non-competition
and non-solicitation during the two year period. In the event of participant's
death, the death benefits of the participant's policy would be immediately paid
to the participant's beneficiary. In the event of disability or retirement of
the participant, the policy benefits would be paid and performance of
non-competition and non-solicitation would not apply. In the


                                       16


event of a change of control of the Corporation, the cash value of the
participant's policy would accrue to the participant but subject to the
non-competition and non-solicitation requirements of the plan.

      Should the Corporation terminate the SERP the full value of the policy at
that time will become the property of the participant.

      The Corporation has entered into individual agreements with the
Corporation's Named Executive Officers:



Participant and                                                               Surrender

Executive Vice President &
Chief Executive Officer


      Prior to the adoption of the SERP, the Corporation had entered into
another supplemental retirement plan, the Management Security Plan. That plan,
in agreement with the participants, was cancelled and all benefits that would
have been due the participants, except for previously employed participants,
were forfeited. The related policies supporting that plan were redeemed and the
cash surrender value of those policies was used to initially fund the SERP.

Severance Agreement

      Effective October 2000, the Board adopted a Severance Agreement
("Agreement") with Mr. Norwood. The Agreement provides certain benefits to Mr.
Norwood in the event his employment is terminated by the Corporation for any
reason other than for cause, which is fully defined in the Agreement.

      In the event of termination, other than for cause, Mr. Norwood would
receive two years' salary to be paid over that period. In addition to salary,
Mr. Norwood would also continue to receive certain insurance benefits for
himself and his family plus other perquisites, the same as he was receiving
prior to termination, for the same two year period.

      As a condition to receiving the salary and benefits Mr. Norwood agrees not
to compete with the Corporation in Tarrant County or disclose any confidential,
proprietary or sensitive corporate information relating to the business of the
Corporation for the period that he receives compensation from the Corporation.

      This Agreement provides the Corporation with assurance that Mr. Norwood
would continue to serve as an executive of the Corporation or a successor in a
change of control situation.

Board Compensation and Benefits Committee Report on Executive Compensation

      Notwithstanding anything to the contrary set forth in any of the
Corporation's previous filings under the Securities Act of 1933, as amended, or
the Securities Exchange Act of 1934, as amended, that might incorporate future
filings, including this Proxy Statement, in whole or in part, the following
report and the Performance Graph shall not be incorporated by reference into any
such filing.

      As of December 31, 2002, the Compensation and Benefits Committee (the
"Committee") is comprised of the following non-employee members of the Board:
William W. Meadows (Chairman), Ronald J. Goldman, F.S. Gunn, Robert L. Herchert
and James L. Murray. Among other duties, the Committee makes recommendations to
the Board with regard to the remuneration of the executive officers and
directors of the Corporation.

      Compensation Philosophy. The Corporation's executive compensation policy
incorporates the fundamental principle that executive compensation should be
linked directly to corporate performance and increases in shareholder value,
while concurrently ensuring that key employees are motivated and retained. The
following objectives set forth the Committee's general guidelines for
compensation decisions:

      -     The Corporation must provide a competitive total compensation
            package that enables the Corporation to attract and retain key
            executives.

      -     All of the Corporation's compensation programs must be integrated
            with the Corporation's annual and long-term business objectives so
            that executives remain focused on the fulfillment of these
            objectives.

      -     The Corporation's compensation package must include a variable
            component that directly links compensation with the overall
            performance of the Corporation, thereby expressly aligning executive
            compensation with the interests of shareholders.

      Elements of Executive Compensation. The Committee regularly reviews the
Corporation's compensation programs to ensure that remuneration levels and
incentive opportunities are competitive and reflect performance by the
Corporation and by the respective executive officer. The various components of
the compensation programs for executive officers are discussed below.

      (i) Base Salary. Base salary levels are largely determined through
comparison with banking organizations of a size similar to the Corporation's.
Surveys are utilized to establish base salaries that are within the range of
those persons holding positions of comparable responsibility at other banking
organizations of a size and complexity similar to the Corporation. Actual base
salaries also are intended to reflect individual performance contributions as
determined through performance evaluations. In addition to individual job
performance and the above-referenced market comparisons, other factors may be
taken into consideration, such as cost of living increases as well as an
individual's perceived potential with the Corporation. All executive officer
base salary levels, which are reviewed annually, are considered by the Committee
to be competitive and within a necessary and reasonable range.


                                       18


      (ii) Performance Compensation Plan. The Board has approved a Performance
Compensation Plan (the "Plan") for use within the Corporation. The Plan is
administered by the Committee. The objective of the Plan is to create
competitive levels of compensation tied directly to the attainment of
performance objectives which the Committee believes are important for achieving
long-term shareholder value. The Plan rewards all employees based on the
attainment of certain goals of the Corporation. The executive officers of the
Corporation are eligible to participate at the same level as all employees in
relationship to their respective base salaries. In addition, the executive
officers through a supplemental program earn additional compensation for
achievement of those goals. The Committee annually determines the executive
officers eligible to participate in the supplemental program of the Plan and the
potential awards to be made for various levels of achievement under the Plan.
The performance goals effective for 2002 included specific goals for growth,
profits, asset quality and operational productivity. In 2002, the Named
Executive Officers participated in the supplemental program for executive
officers of the Corporation.

      All awards under the Plan are contingent on the Corporation attaining
certain basic financial objectives such as return on assets and return on
equity. For the executive officers a portion of each years annual award is
deferred and held by the Corporation for payment at a later date. Under the Plan
the deferral period is two years. The accumulated deferred payments may be
reduced because of less than satisfactory performance in any one year.

      (iii) Stock Options. In 1993 the Board adopted the 1993 Incentive Stock
Option Plan of Summit Bancshares, Inc. which was ratified by the shareholders of
the Corporation at the 1993 annual meeting. In 1997 the Board adopted the 1997
Incentive Stock Option Plan of Summit Bancshares, Inc. which was ratified at the
1997 annual meeting. It is the Corporation's philosophy that awarding stock
options to officers of the Corporation based upon their respective positions and
contributions to the Corporation's overall success will help attract and retain
high quality, results-oriented professionals committed to creating long-term
shareholder value. The activity for 2002 of these plans can be found above under
the heading "Option Exercises and Holdings" and in Note 12 to the Financial
Statements in the Annual Report to Shareholders.

      (iv) Supplemental Executive Retirement Plan. Certain executive officers of
the Corporation participate in a Supplemental Executive Retirement Plan that was
approved by the Board of Directors of the Corporation in 2002 and is
administered by the Committee. This plan is more fully described in this proxy
statement beginning on page 16.

      (v) Severance Agreement. A Severance Agreement has been structured for one
executive officer of the Corporation. This agreement is more fully described in
this proxy statement on page 17.

      Through the programs described above, a significant portion of the
Corporation's executive compensation program is linked directly to individual
and corporate performance and long-term shareholder return. The Committee will
continue to review all elements of executive compensation to ensure that the
total compensation program, and each element therein, meets the Corporation's
objectives and philosophy, as discussed above.


                                       19


2002 Compensation of the Chief Executive Officer

      Mr. Norwood has served as chairman of the board, president and chief
executive officer of the Corporation and Summit Bank, N.A. from January 2001 to
present. Mr. Norwood's 2002 base salary was established by the Board of the
Corporation on the Committee's recommendation, which was based on a survey of
peer group institutions and the factors discussed under "Board Compensation and
Benefits Committee Report on Executive Compensation." Mr. Norwood participates
in the Performance Compensation Plan at the all employee level and the executive
officer level. Because the Corporation did not meet certain basic financial
objectives as required by the Performance Compensation Plan no awards were paid
to employees or executives for performance for 2002. Had awards been made they
would have been paid in January 2003. Mr. Norwood was paid $6,894 in January
2002 that had been deferred from awards earned in 2001 and 2000.

      In November 2001 the Committee granted options to the executive officers
of the Corporation and Mr. Norwood was granted an option to purchase 15,000
shares at a price of $18.40. These options vest ratably over the following five
years on the anniversary date of the grant. The Committee based its decision on
a review of comparative compensation levels within the market of similar
positions.

                                    THE COMPENSATION AND BENEFITS COMMITTEE OF
                                    THE BOARD OF DIRECTORS

                                    William W. Meadows, Chairman
                                    Ronald J. Goldman
                                    F. S. Gunn
                                    Robert L. Herchert
                                    James L. Murray

Compensation Committee Interlocks and Insider Participation

      No member of the Compensation Committee of the Board of Directors of the
Corporation as it was constituted in 2002 was an officer or employee of the
Corporation, or, except for Mr. Murray and Mr. Gunn, the retired Chairman and
retired Vice Chairman of the Board of Directors of the Corporation,
respectively, was formerly an officer of the Corporation or had any
relationships requiring disclosure by the Corporation under Item 404 of
Regulation S-K. During 2002 no executive officer of the Corporation (i) served
as a member of the compensation committee (or other board committee performing
equivalent functions) of another entity, one of whose executive officers served
on the Compensation Committee of the Corporation, (ii) served as a director of
another entity, one of whose executive officers served on the Compensation
Committee of the Corporation, or (iii) was a member of the compensation
committee (or other board committee performing equivalent functions) of another
entity, one of whose executive officers served as a director of the Corporation.

Performance Graph

      The following graph compares the cumulative total shareholder return on
the Common Stock of the Corporation with that of the CRSP Total Return Index
("Total Return Index") for The Nasdaq Stock Market (US) Index, a broad market
index published by the Center for Research in Security Prices at the University
of Chicago, and the NASDAQ Bank Stocks Index ("Bank Stocks Index"), a bank
industry stock index also published by the Center for Research in Security
Prices at the University of Chicago. The comparison for each of the periods
assumes that $100 was invested on December 31, 1997 in each of the Common Stock
of the Corporation, the stocks included in the Total Return Index for The NASDAQ
Stock Market (US) Index and the Bank Stocks Index. These indexes, which reflect
formulas for dividend reinvestment and weighing of individual stocks, do not
necessarily reflect returns that could be achieved by individual investors.

                              CERTAIN TRANSACTIONS

Loans

      Certain of the officers, directors and principal shareholders (and their
affiliates) of the Corporation have deposit accounts and other transactions with
the Corporation, including loans in the ordinary course of business. All loans
or other extensions of credit made by the Corporation to officers, directors and
principal shareholders of the Corporation, and to affiliates of such persons,
were made in the ordinary course of business on substantially the same terms,
including interest rates and collateral, as those prevailing at the time for
comparable transactions with independent third parties and did not involve more
than the normal risks of collectibility or present other unfavorable features.

      The Corporation expects to continue to enter into such transactions all of
which shall be subject to the insider lending restrictions of section 22(h) of
the Federal Reserve Act and are in the ordinary course of business on similar
terms with officers, directors and principal shareholders (and their affiliates)
of the Corporation.

Other Transactions

      During the year ended 2002 the Corporation retained Barlow & Garsek, a
Professional Corporation, to perform legal services. Elliott S. Garsek, a
director of the Corporation, is a shareholder of Barlow & Garsek. Also in 2002,
the Corporation engaged Kelly, Geren & Searcy as real estate brokers or advisors
on certain real estate transactions. Byron B. Searcy, a director of the
Corporation, is a commercial real estate broker affiliated with Kelly, Geren &
Searcy, Inc.

                       ACTION TO BE TAKEN UNDER THE PROXY

      The accompanying proxy will be voted "FOR" election of the nominees for
director and Proposal No. 2 unless the proxy is marked in such a manner as to
withhold authority to so vote.

      The accompanying proxy will also be voted in connection with the
transaction of such other business as may properly come before the Annual
Meeting of Shareholders, or any adjournment or adjournments thereof. Management
knows of no other matters to be considered at the Annual Meeting of
Shareholders. If, however, any other matters properly come before the Annual
Meeting of Shareholders, or any adjournment or adjournments thereof, the persons
named in the accompanying proxy will vote such proxy in accordance with their
best judgment on any such matter. The persons named in the accompanying proxy
will also, if in their judgment it is deemed to be advisable, vote to adjourn
the meeting from time to time.
