Chairman. Robert B. Rodgers, Chairman of the Board of Directors, is an
ex-officio member of the Compensation Committee. In 2003, no Southwest executive
officer served as a member of the compensation committee of another entity that
had an executive officer who served as a Southwest director, and no Southwest
executive officer served as a director of another entity that had an executive
officer serving on Southwest's Compensation Committee.

         Southwest has a Nominating Committee and a Director Search Committee
with responsibility for recommending persons to be nominated as directors. The
Chairman of the Board is the chairman of each committee. Members of the
committees are independent directors within the meaning of the Listing
Standards. The Nominating Committee has responsibility for recommending to the
Board of directors whether or not to nominate each director whose term expires
at the next annual meeting of shareholders. Members of the Nominating Committee
are the independent directors who were elected at the previous annual meeting
and the Chairman of the Board. The Nominating Committee met one time in 2003.
Current members are James E. Berry, II, Joe Berry Cannon, and Robert B. Rodgers,
Chairman. In its determination of whether or not to recommend a director for
nomination, the Nominating Committee considers whether or not such director
meets the minimum criteria for board membership based upon the director's
honesty, integrity, reputation in his or her community, existence of any actual
or potential conflicts of interest, and past service as director, and may
consider additional factors it deems appropriate. The Director Search Committee
has responsibility for identifying and recommending to the Board of directors
persons to be nominated as new directors of Southwest. The Committee also is
responsible for interviewing and investigating potential new directors. The
Director Search Committee met one time in 2003. Current members of the Committee
are J. Berry Harrison, David P. Lambert, Russell W. Teubner, and Robert B.
Rodgers, Chairman. In its determination of whether or not to recommend a
director for nomination, the Director Search Committee will consider whether or
not such director meets the minimum criteria for board membership described
above, and may consider additional factors it deems appropriate.

         The Director Search Committee also is responsible for considering
persons recommended for nomination as directors by shareholders, other
directors, and officers. Under the charter of the

                                       7





Director's Search Committee, no shareholder nomination or recommendation need be
considered unless the Committee determines, in its good faith discretion, that
(i) the manner and substance of the recommendation or nomination and the related
information and materials provided in connection with the recommendation or
nomination complies with the procedural and substantive requirements of
Southwest's Certificate of Incorporation, relevant Bylaws, and state and federal
law, and (ii) if elected, the person recommended or nominated may lawfully serve
on the board. Shareholders may submit recommendations for director candidates
for consideration by the Director Search Committee to the Secretary by first
class mail. Please also see "Shareholder Proposals and Communications" on page
27 of this Proxy Statement.

         The Nominating Committee and the Director Search Committee have written
charters that have been approved by the Board of Directors. Copies of these
charters are available on the governance area of Southwest's website at
www.oksb.com.

         The Board of Directors has determined that all Directors other than Mr.
Green are independent under the Listing Standards.

                              DIRECTOR COMPENSATION

         During 2003, the Chairman of the Board of Directors of Southwest

non-officer Directors of Southwest each received an annual retainer of $8,000.
In addition, non-officer Directors received fees of $750 per board meeting

                             SEVERANCE ARRANGEMENTS

         Under Stillwater National's Severance Compensation Plan, certain
executive officers of Stillwater National 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


                                       12




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 $360,000, $230,800, and $175,000,
respectively, upon a qualifying termination of service if such termination had
occurred on December 31, 2003. Mr. Lanier and Mr. Root are not participants in
the Severance Compensation Plan.

             COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

         As members of the Compensation Committee, 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.

         Southwest seeks to establish market-competitive compensation for its
senior officers that rewards achievement of Southwest goals. Under the
compensation policies of Southwest, which are endorsed by the Compensation
Committee, compensation is paid based both on the senior officer's knowledge,
skills and performance and the performance of Southwest. The base compensation
of the officers is based upon the Committee's assessment of comparable base
salaries and the officer's proficiency and performance. Regular annual bonuses
and grants under Southwest's Stock Option Plan are based upon Southwest's and
the officer's performance. Eighty percent of the annual bonus and option grants
for the Chief Executive Officer is based upon Southwest's performance, and
twenty percent is based upon personal performance. In assessing the performance
of Southwest for purposes of compensation decisions, the Compensation Committee
considers actual versus targeted (i) increases in annual earnings per share,
(ii) annual returns on average shareholders' equity, and (iii) annual returns on
average assets. Awards of regular bonuses are based upon the performance in the
most recent year. Stock option awards are based upon cumulative performance over
a three-year period. Additional performance bonuses and option grants also may
be made within the discretion of the Compensation Committee and the Board of
Directors. The Compensation Committee also may consider other factors, and may
change the basis of assessing Southwest's performance.

                                       13




Southwest's policy is not a plan or contract that conveys rights to base
compensation, bonuses, or grants of options, all of which are discretionary.

         The Committee conducted a review of the Chief Executive Officer's base
compensation in December 2002. As a result of this review, Mr. Green's salary
was increased by $35,000 to $360,000 effective January 1, 2003. A regular bonus
of $90,180 was awarded to Mr. Green in February 2004 based upon 2003
performance.

         All members of the Compensation Committee are independent directors as
defined in the Listing Standards. No member of the Compensation Committee is a
former or current officer or employee of Southwest or any of its subsidiaries.

                                   PROPOSAL II
                     AMENDMENT OF THE 1999 STOCK OPTION PLAN
                          TO INCREASE AVAILABLE SHARES

         At the Annual Meeting, the shareholders are being asked to approve an
amendment to Southwest's 1999 Option Plan in order increase the number of shares
of Common Stock reserved for issuance under the plan, and the number of shares
of Common Stock for which options may be granted, to an aggregate of 1,760,000.
Without this amendment, fewer than 100,000 shares will be available for issuance
under the Plan.

                            REASONS FOR THE AMENDMENT

         Since adoption of the 1999 Option Plan five years ago, awards for an
aggregate of 1,164,704 shares, net of forfeited options, have been granted to
key employees and directors of Southwest or reserved for future issuance in
accordance with the terms of outstanding awards. Only 95,296 shares remain
available for issuance under the Option Plan. The Board of Directors believes
that this number of shares is inadequate to permit Southwest to appropriately
compensate employees, officers and directors in coming years.

         The Board of Directors believes that the availability of a stock based
compensation program intended to provide directors and key employees with at
least a moderate portion of their overall compensation package, and that will
enable them to participate in the growth and prosperity of Southwest as
reflected in the stock price, is necessary in order to attract and retain high
caliber directors, officers, and employees in key positions. The Board of
Directors also believes that such a plan is necessary to align the interests of
such persons with the interests of Southwest's shareholders, which will increase
their incentive to improve Southwest's performance. As such, the Board of
Directors believes that the authorization of additional shares for issuance
under the Option Plan is necessary in order to permit Southwest's continued
growth and profitability.

         If the amendment to the 1999 Option Plan is approved, the total number
of shares subject to issuance under future awards pursuant to the 1999 Option
Plan will be 595,296, or 4.95% of the outstanding Common Stock.

                           PURPOSE OF THE OPTION PLAN

         The purpose of the Option Plan is to advance the interests of Southwest
by providing directors and selected key employees of Southwest and its
affiliates with the opportunity to acquire shares of Southwest's common stock.
By encouraging stock ownership, Southwest seeks to attract, retain, and motivate
the best available personnel for positions of substantial responsibility; to
provide additional incentive to directors and key employees of Southwest and its
affiliates to promote the success of the business as measured by the value of
its shares; and generally to increase the commonality of interests among
directors, key employees, and other shareholders.

         The Option Plan was approved by Southwest shareholders in 1999. It
replaced the Southwest Bancorp 1994 Stock Option Plan. At March 5, 2004, fewer
than 100,000 shares were

                                       16



reserved for issuance under the Option Plan and options of 1,079,712 were
outstanding under the Option Plan and the 1994 Stock Option Plan.

                         DESCRIPTION OF THE OPTION PLAN

         ADMINISTRATION. The Option Plan is administered by a committee (the
"Committee") of at least three directors appointed by the Board, unless the
Board chooses to administer the Plan directly. Subject to the terms of the
Option Plan, the Committee has the authority to select participants and to grant
options and other awards under the Option Plan, to determine the terms of those
awards, and otherwise to administer and interpret the Option Plan. Decisions of
the Committee are final and conclusive. Members of the Committee will be
indemnified to the full extent permissible under Southwest's Certificate of
Incorporation and Bylaws in connection with any claims or other actions relating
to any action taken under the Option Plan. The Board currently intends to
administer the Plan directly with the advice of the Compensation Committee.

         TYPES OF AWARDS; ELIGIBLE PERSONS. The Committee may grant stock
options, stock appreciation rights ("SARs") and restricted stock under the
Option Plan to directors and key employees designated by the Committee. A total
of 48 persons, including all of Southwest's executive officers and all outside
directors, currently participate in the Option Plan. The amount and value of
awards that may be made in the future to directors and named executive officers
are not yet determinable. The Committee has granted only options, and has not
granted SARs or restricted stock awards. The number of options awarded in March
2004 would not have changed if the amendment had been effective at that date,
but future awards may be reduced or eliminated if the amendment is not approved.

         Options may be either incentive stock options ("ISOs") as defined in
Section 422 of the Internal Revenue Code (the "Code"), or options that are not
ISOs ("Non-ISOs"). Directors who are not employees are not eligible to receive
ISOs.

         FINANCIAL EFFECTS OF AWARDS. Southwest will receive no monetary
consideration for the granting of awards under the Option Plan. It will receive
no monetary consideration other than the option price for shares of common stock
issued to optionees upon the exercise of their options. It will receive no
monetary consideration upon the exercise of SARs or the vesting of restricted
stock. Under current accounting standards adopted by Southwest, recognition of
compensation expense is not required when stock options are granted at the fair
market value of the common stock on the date the option is granted. Stock
options are considered, however, in the calculation of diluted earnings per
share of Southwest. Awards of SARs generally require recognition of compensation
expense based upon the difference between their exercise price and the market
value of the shares to which they relate. Awards of restricted stock generally
require the recognition of compensation expense based upon the market value of
the stock. The accounting treatment of awards is subject to change based upon
future actions by the SEC and accounting rule-making organizations.

         SHARES AVAILABLE FOR GRANTS. The Option Plan reserves authorized but
unissued shares of common stock for issuance upon the exercise of options SARs,
or the grant of restricted stock. In the event of any merger, consolidation,
recapitalization, reorganization, reclassification, stock dividend, split-up,
combination of shares or similar event in which the number or kind of shares
is changed without receipt or payment of consideration by Southwest, the number
and kind of shares
                                       17



of stock as to which options, SARs and restricted stock may be awarded under the
Option Plan, the affected terms of all outstanding options, SARs and shares of
restricted stock, and the aggregate number of shares of common stock remaining
available for grant under the Option Plan will be adjusted. Generally, the
number of shares as to which SARs are granted are charged against the aggregate
number of shares available for grant under the Option Plan, provided that, in
the case of an SAR granted in conjunction with an option, under circumstances in
which the exercise of the SAR results in termination of the option and vice
versa, only the number of shares of common stock subject to the option shall be
charged against the aggregate number of shares of common stock remaining
available under the Option Plan. If awards should expire, become unexercisable,
or be forfeited for any reason without having been exercised or become vested in
full, the shares of common stock subject to such awards shall, unless the Option
Plan shall have been terminated, be available for the grant of additional awards
under the Option Plan.

         DURATION OF THE OPTION PLAN AND GRANTS. The Option Plan has a term of
10 years from February 18, 1999, its effective date, after which date no awards
may be granted. The maximum term for an award is ten years from the date of
grant, except that the maximum term of an ISO (and an SAR granted in tandem with
an ISO) may not exceed five years if the optionee owns more than 10% of the
common stock on the date of grant. The expiration of the Option Plan, or its
termination by the Committee, will not affect any award then outstanding.

         OPTIONS. The exercise price of options may not be less than 100% of the
fair market value of the common stock on the date of grant. In the case of an
optionee who owns more than 10% of the outstanding common stock on the date of
grant, the option price may not be less than 110% of fair market value of the
shares. As required by federal tax laws, to the extent that the aggregate fair
market value (determined when an ISO is granted) of the common stock with
respect to which ISOs are exercisable by an optionee for the first time during
any calendar year (under all Option Plans of Southwest and of any subsidiary)
exceeds $100,000, the options will be treated as Non-ISOs, and not as ISOs. In
the event that the fair market value per share of the common stock falls below
the exercise price of previously granted options, the Committee will have the
authority, with the consent of the optionee, to cancel outstanding options and
to issue new options with an exercise price equal to the then current fair
market price per share of the common stock.

         SARS. An SAR may be granted in tandem with all or part of any option
granted under the Option Plan or without any relationship to any option. An SAR
granted in tandem with an ISO must expire no later than the ISO, must have the
same exercise price as the ISO and may be exercised only when the ISO is
exercisable and when the fair market value of the shares subject to the ISO
exceeds the exercise price of the ISO. For SARs granted in tandem with options,
the optionee's exercise of the SAR cancels his right to exercise the option, and
vice versa. Regardless of whether an SAR is granted in tandem with an option,
exercise of the SAR will entitle the optionee to receive, as the Committee
prescribes in the grant, all or a percentage of the difference between (i) the
fair market value of the shares of common stock subject to the SAR at the time
of its exercise, and (ii) the fair market value of such shares at the time the
SAR was granted (or, in the case of SARs granted in tandem with options, the
exercise price). The exercise price as to any particular SAR shall not be less
than the fair market value of the optioned shares on the date of grant.

         EXERCISE OF OPTIONS AND SARS. The exercise of options and SARs will be
subject to the terms and conditions established by the Committee in a written
agreement between the Committee

                                       18



and the optionee. In the absence of Committee action to the contrary: (A) an
otherwise unexpired ISO shall cease to be exercisable upon (i) an employee's
termination of employment for "just cause" (as defined in the Option Plan), (ii)
the date three months after an employee terminates service for a reason other
than just cause, death, or disability, or (iii) the date one year after an
employee terminates service due to disability, or two years after termination of
such service due to his death; (B) an unexpired Non-ISO shall be exercisable at
any time (but not later than the date on which the Non-ISO would otherwise
expire.) Notwithstanding the provisions of any option which provides for its
exercise in installments as designated by the Committee, such option shall
become immediately exercisable upon the optionee's death or permanent and total
disability.

         An otherwise exercisable SAR may be exercised only during the period
beginning on the third business day following the release for publication of
Southwest's quarterly or annual financial information, and ending on the twelfth
business day following such date. In no event, however, will any option or SAR
be exercisable after its expiration date, as to fractional shares of common
stock or prior to the optionee's satisfaction of any income tax withholding
requirements.

         A participant may exercise options or SARs, subject to provisions
relative to their termination and limitations on their exercise, only by (i)
written notice of intent to exercise the option or SAR with respect to a
specified number of shares of common stock, and (ii) in the case of options,
payment to Southwest (contemporaneously with delivery of such notice) in cash,
in common stock, or a combination of cash and common stock, of the amount of the
exercise price for the number of shares with respect to which the option is then
being exercised. Common stock utilized in full or partial payment of the
exercise price for options shall be valued at its market value at the date of
exercise. Although directors and executive officers of Southwest generally would
be prohibited from profiting from certain purchases and sales of shares within
any six-month period under the federal securities laws, they generally will not
be prohibited by such laws from exercising options and immediately selling the
shares they receive, provided at least six months elapses between the grant of
the option and the sale of the common stock purchased on exercise of the option.
As a result, officers, like Southwest's and its affiliates' other participating
employees, generally will be permitted to benefit in the event the market price
for the shares exceeds the exercise price of their options, without being
subject to loss in the event the market price falls below the exercise price.

         RESTRICTED STOCK. The Committee has broad discretion at the time of
making a restricted stock grant to determine a period of between six months and
five years during which the shares granted will be subject to restrictions, and
the conditions that must be satisfied in order for the shares of restricted
stock to become unrestricted (i.e., vested and nonforfeitable). For example, the
Committee may condition vesting upon a grantee's continued employment or upon
the grantee's attainment of specific corporate, divisional, or individual
performance standards or goals. The Committee may impose special vesting rules
applicable if the grantee retires, becomes disabled, or dies before the
expiration of the restriction period or satisfaction of the restrictions
applicable to an award of restricted stock.

         The Committee shall determine the percentage of the award of restricted
stock which shall vest in the event of death, disability, or retirement prior to
the expiration of the restriction period or the satisfaction of the restrictions
applicable to an award of restricted stock. Notwithstanding the restriction
period and the restrictions imposed by the Committee on the restricted stock,
the

                                       19



Committee may shorten the restriction period or waive any restrictions if the
Committee concludes that it is in the best interests of Southwest to do so.

         Until a grantee's interest vests, his or her restricted stock is
nontransferable and forfeitable. Nevertheless, the grantee is entitled to vote
the restricted stock and to receive dividends and other distributions made with
respect to the restricted stock. To the extent that a grantee becomes vested in
his or her restricted stock at any time during the restriction period and has
satisfied applicable income tax withholding obligations, Southwest will deliver
unrestricted shares of common stock to the grantee. At the end of the
restriction period, the grantee will forfeit to Southwest any shares of
restricted stock as to which he or she did not earn a vested interest during the
restriction period.

         CHANGE IN CONTROL. Upon a change in control, all options and SARs are
immediately exercisable and fully vested, and all shares of restricted stock
become fully vested. At that time, the Committee may grant the optionee the
right to receive a cash payment in an amount equal to the excess of the market
value of the shares subject to an option over the exercise price of the option.
If there is (i) a liquidation or dissolution of Southwest, (ii) a merger or
consolidation in which Southwest is not the surviving entity; or (iii) the sale
or disposition of all or substantially all of Southwest's assets, then all of
the outstanding options must be surrendered in return for options for shares of
the acquiring company, shares of the acquiring company with a market value equal
to the excess of the market value of the shares subject to option on the date of
the transaction over the exercise price of the option, or cash equal to the
excess of the market value of the shares subject to option on the date of the
transaction over the exercise price of the option, as determined by the
Committee. In no event, however, may an option be exchanged for cash or an SAR
exercised within the six-month period following the date of its grant.

         A change in control under the Option Plan means any one of the
following events: (1) the acquisition of ownership or control of 51% or more of
any class of voting securities of Southwest or Stillwater National; (2) the
exercise of a controlling influence over the management or policies of
Stillwater National or Southwest by any person or by persons acting as a group
within the meaning of Section 13(d) of the Securities Exchange Act of 1934, or
(3) the failure of Continuing Directors to constitute at least two-thirds of the
Board of Southwest or Stillwater National during any period of two consecutive
years. A change in control does not include acquisition of ownership or control
of voting securities of Southwest by an employee benefit plan sponsored by
Southwest or Stillwater National; acquisition of voting securities by Southwest
through share repurchase or otherwise; or acquisition by an exchange of voting
securities with a successor to Southwest in a reorganization, such as a
re-incorporation, that does not have the purpose or effect of significantly
changing voting power or control. Continuing directors are those individuals who
were directors at the Effective Date of the Option Plan and those other
individuals whose election or nomination for election as a director was approved
by a vote of at least two-thirds of the continuing directors then in office. An
offer to effect a change in control means any offer to buy or acquire,
solicitation of an offer to sell, tender offer for, or request of invitation for
tenders of, 25% or more of any class of voting securities of Southwest for
value. The decision of the Committee as to whether a change in control has
occurred or an offer to effect a change in control has been received is
conclusive and binding.

         Although these provisions are included in the Option Plan primarily for
the protection of an employee-optionee in the event of a change in control of
Southwest, they may also be regarded as

                                       20



having a takeover defensive effect, which may reduce Southwest's vulnerability
to hostile takeover attempts and certain other transactions which have not been
negotiated with and approved by the Board.

         NONTRANSFERABILITY. ISOs may not be sold, pledged, assigned,
hypothecated, transferred or disposed of in any manner other than by will or by
the laws of descent and distribution, or pursuant to the terms of a qualified
domestic relations order. Other awards may not be sold, pledged, assigned,
hypothecated, transferred or disposed of in any manner other than by will or by
the laws of descent and distribution, pursuant to the terms of a qualified
domestic relations order, or, in the sole discretion of the Committee, in
connection with a transfer for estate or retirement planning purposes to a trust
established for such purposes.

         CONDITIONS ON ISSUANCE OR SALE OF SHARES. The Committee has the
authority to impose restrictions on shares issued under the Option Plan that it
deems appropriate or desirable, including the authority to impose a right of
first refusal or to establish repurchase rights or both of these restrictions.
The Committee may not issue shares unless the issuance complies with applicable
securities laws, and to that end may require that an optionee or grantee make
certain representations or warranties. In addition, no shares that have been
acquired upon exercise of an option may be sold or otherwise disposed of (except
by gift or upon death) before the end of a six-month period that begins on the
date the option was granted.

         AMENDMENT AND TERMINATION OF THE OPTION PLAN. The Board may from time
to time amend the terms of the Option Plan and, with respect to any shares at
the time not subject to options, suspend or terminate the Option Plan.
Shareholder approval is required for an amendment that would increase the number
of shares subject to the Option Plan or that would extend the term of the Option
Plan. No amendment, suspension or termination of the Option Plan will, without
the consent of any affected holders of an option, alter or impair any rights or
obligations under the option.

FEDERAL INCOME TAX CONSEQUENCES

         ISOS. An employee recognizes no taxable income upon the grant of ISOs.
If the optionee holds the option shares for at least two years from the date the
ISO is granted and one year from the date the ISO is exercised, any gain
realized on the sale of the shares received upon exercise of such ISO is taxed
as long-term capital gain. However, the difference between the fair market value
of the stock at the date of exercise and the exercise price of the ISO will be
treated as an item of tax preference in the year of exercise for purposes of the
alternative minimum tax. If the employee disposes of the shares before the
expiration of either of the special holding periods, the disposition is a
"disqualifying disposition." In this event, the employee will be required, at
the time of the disposition of the stock, to treat the lesser of the gain
realized or the difference between the exercise price and the fair market value
of the stock at the date of exercise as ordinary income and the excess, if any,
as capital gain.

         Southwest will not be entitled to any deduction for federal income tax
purposes as the result of the grant or exercise of an ISO, regardless of whether
or not the exercise of the ISO results in liability under the alternative
minimum tax. However, if the employee has ordinary income taxable as
compensation as a result of a disqualifying disposition, Southwest will be
entitled to deduct an


                                       21




equivalent amount, subject to federal income tax limitations on annual executive
compensation deductions.

         NON-ISOS. In the case of a Non-ISO, an optionee will recognize ordinary
income upon the exercise of the Non-ISO in an amount equal to the difference
between the fair market value of the shares on the date of exercise and the
option price (or, if the optionee is subject to certain restrictions imposed by
the federal securities laws, upon the lapse of those restrictions unless the
optionee makes a special tax election within 30 days after the date of exercise
to have the general rule apply). Upon a subsequent disposition of such shares,
any amount received by the optionee in excess of the fair market value of the
shares as of the exercise will be taxed as capital gain. Southwest will be
entitled to a deduction for federal income tax purposes at the same time and in
the same amount as the ordinary income recognized by the optionee in connection
with the exercise of a Non-ISO, subject to federal income tax limitations on
annual executive compensation deductions.

         SARS. The grant of an SAR has no tax effect on the optionee or
Southwest. Upon exercise of the SARs, however, any cash or common stock received
by the optionee in connection with the surrender of his or her SAR will be
treated as compensation income to the optionee, and Southwest will be entitled
to a business expense deduction for the amounts treated as such compensation
income, subject to federal income tax limitations on annual executive
compensation deductions.

         RESTRICTED STOCK. The grant of restricted stock has no tax effect on
Southwest or the grantee. When the shares become vested pursuant to the
restricted stock award, the grantee will recognize ordinary income equal to the
fair market value of the shares delivered to him or her under the restricted
stock award, and Southwest will be entitled to a business expense deduction in
the same amount, subject to federal income tax limitations on annual executive
compensation deductions.

RECOMMENDATION AND VOTE REQUIRED

         Approval of the Option Plan requires the favorable vote of a majority
of the votes represented at the Annual Meeting (assuming a quorum of a majority
of the outstanding shares of common stock is present).

         THE BOARD RECOMMENDS A VOTE "FOR" APPROVAL OF THE AMENDMENT TO THE
OPTION PLAN.

                              CERTAIN TRANSACTIONS

         Southwest's banking subsidiaries have and expect to have in the future,
banking and other transactions with certain officers and directors of Southwest
and its subsidiaries and with 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.

                                       22




             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
2003. 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.

                            PREAPPROVAL OF SERVICES

         The Audit Committee is required to preapprove all auditing services and
permitted non-audit services provided by Southwest's independent auditors, under
Securities and Exchange Commission regulations that became effective in May
2003. There is an exception for preapproval of nonaudit services if the
aggregate amount of all such non-audit services provided to Bancorp constitutes
not more than 5 percent of the total amount of revenues paid by it to its
independent auditors during the fiscal year in which the non-audit services are
provided; such services were not recognized by Southwest at the time of the
engagement to be non-audit services; and the non-audit services are promptly
brought to the attention of the committee and approved prior to the completion
of the audit by the committee or by one or more members of the committee to whom
authority to grant such approval has been delegated by the committee. All audit
services and permitted non-audit services to be performed by Southwest's
independent auditor have been preapproved by the Audit Committee as required by
Securities and Exchange Commission regulations and the Audit Committee's charter
without exception.

                          REPORT OF THE AUDIT COMMITTEE

         The Southwest Audit Committee oversees and reports to the Board of
Directors regarding accounting and financial reporting processes, the audits of
the financial statements, the qualifications and independence of independent
auditors engaged to provide independent audits and related services, and the
performance of the internal audit function and independent auditors; and also
performs the other duties of the committee specified by federal securities laws
and regulations, the Federal Deposit Insurance Act and related regulations, the
Listing Standards and its charter. The Committee (1) has reviewed and discussed
the audited financial statements included in Southwest's 2003 Annual Report on
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 2003 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.

                                 CODE OF ETHICS

         The Board of Directors of Southwest has adopted a code of ethics that
applies to all directors, officers, and employees of Southwest and its
consolidated subsidiaries. This code, which fulfills the requirements of the
Listing Standards and the criteria established by applicable


                                       24



SEC regulation, is available through the governance area of Southwest's website
at www.oksb.com.

                                  OTHER MATTERS

         The Board is not aware of any business to come before the Annual
Meeting other than those matters described above in this Proxy Statement and
matters incident to the conduct of the Annual Meeting. However, if any other
matters should properly come before the Annual Meeting, it is intended that
proxies in the accompanying form will be voted as determined by a majority of
the Board of Directors.

                    SHAREHOLDER PROPOSALS AND COMMUNICATIONS

         Any shareholder proposal to take action at the year 2005 Annual Meeting

Main Street, Stillwater, Oklahoma 74074 no later than November 17, 2004, in
order to be eligible for inclusion in Southwest's proxy materials for that
meeting. Any such proposals shall be subject to the requirements of the proxy
rules adopted under the Securities Exchange Act of 1934. Under Southwest's
Certificate of Incorporation, a shareholder proposal or nomination for director
may be eligible for consideration at an annual or special meeting if written
notice is delivered or mailed to the Secretary not less than thirty days nor
more than sixty days before the meeting, provided that, if less than forty days

         The board of directors believes it is important for all directors to
attend the annual meeting of shareholders in order to show their support for
Southwest and to provide an opportunity for shareholders to express any concerns
to them. Southwest has adopted a policy that all directors should attend each
annual meeting of shareholders unless they are unable to attend by reason of
personal or family illness or pressing matters.

                          JOINT AUDIT COMMITTEE CHARTER

                     I. PURPOSE AND GENERAL RESPONSIBILITIES

1.  The Audit Committee:

    a.    Oversees and reports to the Board of Directors regarding (a)
          accounting and financial reporting processes, (b) audits of the
          financial statements, (c) the qualifications and independence of
          Registered Public Accounting Firms ("Independent auditors") engaged to
          provide independent audits and related services, and (d) the
          performance of the internal audit function and independent auditors;

    b.    Performs the other duties of the committee specified by federal
          securities laws and regulations, the Federal Deposit Insurance Act and
          related regulations (the "FDIA"), the listing standards of the NASDAQ
          Stock Market, Inc. ("Listing Standards"), and this charter.

    c.    In addition to its other duties and powers specified in this
          charter, as directed by the Board, investigates and reports to the
          Board with respect to specific matters involving financial reporting,
          financial accounting, conflicts of interest, internal controls, and
          compliance with laws and regulations relating to such matters.

                               II. JOINT COMMITTEE

2.   Meetings of Southwest 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.

                  III. RELATIONSHIPS WITH INDEPENDENT AUDITORS

3.   The independent auditors are ultimately accountable to the Board and to
     the committee, as representatives of the shareholders. The committee,
     in its capacity as a committee of the Board, is directly responsible
     for the appointment, compensation, retention, evaluation, termination,
     and oversight of the work of any independent auditor employed by
     Southwest for the purpose of preparing or issuing an audit report or
     related work. The independent auditors report directly to the
     committee.

4.   The committee is responsible for the resolution of any disagreements
     between management of Southwest and the independent auditors regarding
     financial reporting.

5.   At least annually, the committee:

     a.   Reviews with management and the independent auditors the reports
          required to be provided to the committee by the independent auditor by
          Section 10A of the Securities Exchange Act of 1934 ("Section 10A"),
          the scope of services required by the audit, major risk factors,
          critical accounting policies, alternative treatments of financial
          information, audit conclusions regarding significant accounting
          estimates, and the compliance of the audit with the audit procedures
          required by

                                      A-2



          Section 10A relating to detection of illegal acts, identification of
          related party transactions, and evaluation of Southwest as a going
          concern.

     b.   Receives and considers a formal written statement from the
          independent auditor delineating all relationships between the auditor
          and Southwest, as required by Independent Standards Board Standard No.
          1, and actively engages in a dialogue with the independent auditor
          with respect to any disclosed relationships or services that may
          affect the objectivity and independence of the auditors and takes
          appropriate action to oversee the independence of the independent
          auditor.

6.   The committee discusses with management and the independent auditors any
     illegal acts reported to the committee by the independent auditors that the
     independent auditor detected or which otherwise came to the independent
     auditor's attention in the course of the audit, and recommends that the
     Board take appropriate remedial action.

                         IV. APPROVAL OF AUDIT SERVICES

7.   All auditing services (including, without limitation, comfort or "agreed
     upon procedures" letters in connection with securities underwritings) and
     permitted non-audit services, other than as provided by section 8, below,
     provided to Southwest by its independent auditors shall be preapproved by
     the committee. Approval of the committee may be obtained by majority vote
     of the committee members at any meeting of the committee or by written
