- --------------------------------------------------------------------------------

                      PROPOSAL I -- ELECTION OF DIRECTORS

         Your Board of Directors is currently composed of thirteen members. All
of Southwest's directors also serve as directors of the Stillwater National Bank
and Trust Company, Southwest's banking subsidiary. Directors of Southwest are
divided into three classes and are elected for terms of three years and until
their successors are elected and qualified. At the Annual Meeting, five
directors will be elected for terms expiring at the 2004 Annual Meeting.

         The Board of Directors has nominated for re-election, Thomas D. Berry,
Rick Green, David P. Lambert, Linford R. Pitts, and Stanley R. White, all of
whom are currently directors, each to serve for a term of three years and until
his successor is elected and qualified. Each nominee must be elected by a
plurality of shares voted in this election. The individuals named as proxies on
your proxy card will vote for the election of each nominee unless you withhold
authorization.

                                       2


         Each shareholder voting in the election of directors is entitled to
cumulate his or her votes by multiplying the number of shares of common stock
owned of record by the shareholder on the Record Date by the number of directors
to be elected. Each shareholder is then entitled to cast his or her total
cumulated votes for one nominee or distribute his or her votes among any number
of the nominees being voted on at the Annual Meeting. Shareholders may not
cumulate their votes on the form of proxy solicited by the Board of Directors.
In order to cumulate votes, shareholders must attend the meeting and vote in
person or make arrangements with their own proxies. Unless otherwise specified
in the proxy, however, the right is reserved, in the sole discretion of the
Board of Directors, to vote cumulatively, and to distribute votes among some or
all of the nominees of the Board of Directors in a manner other than equally so
as to elect as directors the maximum possible number of such nominees.

         Each nominee has agreed to serve a three-year term, if elected. If any
nominee is unable to stand for re-election at this Annual Meeting, the Board may
reduce its size or nominate an alternate candidate, and the proxies will be
voted for the alternate candidate.

         Your Board recommends a vote FOR these directors.

Listing Standards. The Committee has adopted a written charter, which has been
approved by the Board of Directors. A copy of this charter is attached as Annex

                            Severance Arrangements

     Stillwater National has adopted a Severance Compensation Plan pursuant to
which Messrs. Green, White, and Crowell are entitled to lump-sum severance
compensation upon a qualifying termination of service equal to a percentage of
their respective total annual base compensation in effect at the date of
termination. For purposes of the Severance Compensation Plan, a qualifying
termination of service is defined as either an involuntary termination of
service or a voluntary termination of service for good reason, in either case
within two years following a change-in-control occurring after the effective
date of the Severance Compensation Plan. Good reason would include: (i) a
reduction in their base salary; (ii) their assignment without their consent to a
location other than in Oklahoma; (iii) the failure to maintain them in a
position of comparable authority or responsibility; or (iv) a material reduction
in their level of incentive compensation or benefits. A change-in-control is
deemed to occur whenever: (i) any entity or person becomes the beneficial owner
of or obtains voting control over 50% or more of the outstanding shares of
common stock of either Southwest or Stillwater National; (ii) the shareholders
of either Southwest or Stillwater National approve (a) a merger or consolidation
in which Southwest or Stillwater National is not the survivor or pursuant to
which the outstanding shares of either would be converted into cash, securities
or other property of another corporation other than a transaction in which
shareholders maintain the same proportionate ownership interests, or (b) a sale
or other disposition of all or substantially all of the assets of either
Southwest or Stillwater National; or (iii) there shall have been a change in a
majority of the Boards of Directors of either Southwest or Stillwater National
within a twelve-month period unless each new director was approved by the vote
of two-thirds of the directors still in office who were in office at the
beginning of the twelve-month period. Messrs. Green, White, and Crowell would
have received lump-sum severance payments of $250,000, $150,000 and $130,000,
respectively, upon a qualifying termination of service if such termination had
occurred on December 31, 2000.

            Compensation Committee Report on Executive Compensation

     As members of the Compensation Committees of Southwest and Stillwater
National, it is our duty to review compensation policies applicable to senior
officers; to consider the relationship of corporate performance to that
compensation; to recommend salary and bonus levels for senior officers for
consideration by the Boards of Directors of Southwest and Stillwater National;
and to administer various incentive plans of Southwest and Stillwater National.

     Overview. Under the compensation policies of Southwest, which are endorsed
by the Compensation Committee, compensation is paid based both on the senior
officer's performance and the performance of the entire Company. In assessing
the performance of Southwest and Stillwater National for purposes of
compensation decisions, the Compensation Committee considers a number of
factors, including salaries paid by financial services companies with
characteristics similar to Bancorp's to officers with similar responsibilities,
profits of Southwest and Stillwater National during the past year relative to
their profit plans, reports of federal regulatory examinations of Southwest and
Stillwater National, growth, business plans for future periods, regulatory
capital levels, and changes in the value of Southwest's stock. The Compensation
Committee assesses individual executive performance based upon its determination
of the officer's

                                       12


contributions to the performance of Southwest and the accomplishment of
Southwest's strategic goals, such as the completion of Southwest's public
offerings of common stock in 1993 and 1999, Preferred Stock in 1995, and Trust
Preferred Securities in 1997. In assessing performance for the purposes of
establishing base salaries for 2000 and previous years, the members of the
Committee did not make use of a mechanical weighting formula or use specific
performance targets, but instead weighted the described factors as they deemed
appropriate in the total circumstances.

     Base Salary. The 2000 salary levels of Southwest's Chief Executive Officer
and other Named Executive Officers were established consistent with this
compensation policy. The Committee conducted a review of executive officer base
compensation in December 1999. Changes in base compensation for 2000 were
effective on January 1, 2000. In its review, the Committee determined that the
performance of Mr. Green was excellent, based upon the factors described above.
As a result of this review and in recognition of Mr. Green's expanded
responsibilities following the retirement of the Vice Chairman, Mr. Green's
salary was increased by $75,000 to $250,000.

     Bonuses. Stillwater National also awarded performance bonuses. In December
2000, a bonus of $12,500 was awarded to Mr. White, $10,946 to Mr. Poole, and
$10,000 each to Mr. Crowell and Mr. Root. In addition, a bonus of $76,250 was
awarded to Mr. Green in January 2001 based upon Southwest's earnings per share,
return on assets, and return on equity levels achieved for 2000.

     Stock Options. The purposes of Southwest's Stock Option Plans (the "Option
Plans") are to attract, retain and motivate key officers of Southwest and
Stillwater National by providing key officers with a stake in the success of
Southwest, as measured by the value of its shares, and to increase the
commonality of interests among key employees and other shareholders. Options are
granted at exercise prices equal to the fair market value of the shares on the
dates of grant. During 2000, incentive stock options for 47,000 shares were
granted to Named Executive Officers at an exercise price of $15.78 per share,
including options for 20,000 shares granted to Mr. Green, 8,000 shares granted
to Mr. Root, 7,000 shares each granted to Mr. White and Mr. Poole, and 5,000
shares granted to Mr. Crowell.

     No member of the Compensation Committee is a former or current officer or
employee of Southwest or Stillwater National.

                                CERTAIN TRANSACTIONS

     Stillwater National has and expects to have in the future, banking
transactions with certain officers and directors of Southwest and Stillwater
National and greater than 5% shareholders of Southwest and their immediate
families and associates. These transactions are in the ordinary course of
business, and loans have been and will be made on substantially the same terms,
including interest rates and collateral, as those prevailing at the time for
comparable transactions with other persons. In the opinion of Southwest's
management, these loans did not involve more than normal risk of collectibility
or present other unfavorable features.

                                       14


             SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

         Based solely on Southwest's review of the copies of initial statements
of beneficial ownership on Form 3 and reports of changes in beneficial ownership
on Form 4 that it has received in the past year, annual statements of changes in
beneficial ownership on Form 5 with respect to the last fiscal year, and written
representations that no such annual statement of change in beneficial ownership
was required, all directors, executive officers, and beneficial owners of more
than 10% of its common stock have timely filed those reports with respect to
2000. Southwest makes no representation regarding persons who have not
identified themselves as being subject to the reporting requirements of Section
16(a) of the Securities Exchange Act of 1934, or as to the appropriateness of
disclaimers of beneficial ownership.

                RELATIONSHIP WITH INDEPENDENT PUBLIC ACCOUNTANTS

         A representative of Ernst & Young LLP, Southwest's independent
certified public accounting firm, is expected to be present at the Annual
Meeting to respond to shareholders' questions and will have the opportunity to
make a statement.

         Audit Fees. Ernst & Young LLP billed a total of $135,000 for the audit
of Southwest's financial statements included in the annual report on Form 10-K
for the year-ended December 31, 2000, and the review of quarterly reports on
Forms 10-Q filed during that year.

         Other Fees. Ernst & Young LLP billed a total of $31,500 for other
services for the year ended December 31, 2000, including $14,000 for audit of
Southwest's profit sharing plan.

         Change in Auditors. On August 28, 2000, Southwest dismissed Deloitte &
Touche LLP, which had previously served as independent accountants for
Southwest. The reports of Deloitte & Touche LLP on the consolidated financial
statements of Southwest as of and for the fiscal years ended December 31, 1999
and December 31, 1998 contained no adverse opinion or disclaimer of opinion and
were not qualified or modified as to uncertainty, audit scope, or accounting
principles. The change in independent accountants was recommended by Southwest's
Audit Committee and approved by Southwest's Board of Directors. In connection
with its audit for the fiscal years ended December 31, 1999 and 1998, and in the
interim period from January 1, 2000 through August 28, 2000, there were no
disagreements with Deloitte & Touche LLP on any matter of accounting principles
or practices, financial statement disclosure, or auditing scope or procedure,
which disagreements, if not resolved to the satisfaction of Deloitte & Touche
LLP, would have caused Deloitte & Touche LLP to make reference to such
disagreements in its report on the consolidated financial statements for such
years.

         On August 31, 2000, Southwest engaged Ernst & Young LLP as its new
independent accountants. The engagement of Ernst & Young LLP was recommended by
Southwest's Audit Committee and approved by Southwest's Board of Directors.

                          Report of the Audit Committee

The Southwest audit committee reviews and reports to the board of directors
regarding the performance of the internal audit function and independent
auditors, the integrity of the financial

                                       15


statements, management's efforts to maintain a system of internal controls, and
compliance with legal and regulatory requirements. The committee (1) has
reviewed and discussed the audited financial statements included in Southwest's
2000 Annual Report and Form 10-K with management; (2) has discussed with
independent auditors the matters required to be discussed by Statement of
Auditing Standards 61; and (3) has received the written disclosures and the
letter from the independent auditors required by Independence Standards Board
Standard No. 1, and has discussed independence with the independent auditor.
Based upon this review, discussion, disclosures, and materials described in (1)
through (3), the committee recommended to the Board of Directors that the
audited financial statements be included in the 2000 Annual Report and Form 10-
K. The committee also has considered whether the amount and nature of non-audit
services rendered by the independent accountant are consistent with its
independence.

Reporting: The Committee reports to the full Board of Directors of the Company.
The Board of Directors of the Company establishes the Charter, membership, and
duties of the Committee, and, as representatives of the shareholders, has the
ultimate authority and responsibility to select, evaluate, and

                                       2


where appropriate, replace the independent auditors. The independent auditors
are accountable to the Audit Committee and the Board of Directors as
representatives of the shareholders.

Membership: The Board of Directors establishes the number of members, the
membership of the Committee, and the Chairman of the Committee at the annual
organizational meeting and at other times the Board deems appropriate. The
Committee consists of at least three members. All members are outside,
independent directors. The membership meets the independence, experience, and
other requirements of the Nasdaq National Market and the FDIA.

Meeting Frequency: The Committee meets at least quarterly, and at such other
times as are established by the Chairman, the Committee, or the Board.

Conduct of Meetings; Joint Committee: The Committee establishes reasonable rules
for the conduct of meetings and required notice of meetings, subject to
oversight by the Board of Directors. The Committee meets by conference call or
in person. Minutes of the Committee are not required, but may be kept. Reports
and recommendations to the Board of Directors are written. Meetings of the
Company and Bank Committees are held jointly. Each Board has authority with
respect to its Committee. The Committees and the Boards are referred to in the
singular in this charter from time to time for convenience.

Authority, Support, and Advice: The Committee's functions are supported by the
Chief Financial Officer. The Committee may hold meetings with independent
auditors, internal audit personnel, outside counsel to the Company and the Bank,
and others as it deems appropriate. The Committee is advised by the independent
auditors and the Company's outside counsel, and also may, but is not required
to, engage separate counsel or other advisors to the Committee. The Committee
may rely on these advisors regarding the application, contents, and meaning of
auditing and accounting standards, laws, and regulations. The Committee may rely
on the independent auditors to identify the matters required to be discussed and
disclosed by the independent auditors.

Responsibilities of Management and Independent Auditors. While the Committee has
the review, oversight, and reporting responsibilities set forth in this charter,
it does not have responsibility for planning or conducting audits or for
determining that the financial statements are complete and accurate and are in
accordance with generally accepted accounting principles. Those are
responsibilities of management and the independent auditors, rather than the
Committee. The Committee also is not responsible for ensuring compliance with
laws or regulations, or for resolving disagreements, if any, between management
and the independent auditor.
