percentage of his compensation may be less than the percentages payable to other
employees' accounts under Primary Plan by reason of provisions of the Code
applicable to such qualified plans.

         WHEREAS, Stillwater National has established this Stillwater National
Bank and Trust Company Supplemental Profit Sharing Plan and Agreement (the
"Plan"), in order that it may make tax-deferred contributions to a plan for the

         (w)      "Transaction" means (i) the liquidation or dissolution of
                  Southwest, (ii) a merger or consolidation in which Southwest
                  is not the surviving entity; or (iii) the sale or other
                  disposition of all or substantially all of the voting
                  securities or assets of Stillwater National.

         (x)      "Trust" means an irrevocable grantor trust established by
                  Stillwater National, or a successor thereto, in connection
                  with this Plan to provide the benefits described in the Plan,
                  the assets of which are subject to the claims of Stillwater
                  National's creditors in the event of bankruptcy or insolvency,
                  and the terms of which conform to the terms of the model trust
                  as descried in IRS Revenue Procedure 92-64 (and any successor
                  thereto) and otherwise meet the requirements for a "rabbi
                  trust" under ERISA and the Code and of the provisions of this
                  Plan.

         (y)      "Trustee" means the independent third-party corporation or
                  individual selected by Stillwater National to serve as Trustee
                  for the Trust.

2.       PLAN ACCOUNT. Stillwater National shall establish and maintain the Plan
Account for the benefit of the Executive or for the benefit of his designated
beneficiary upon the death of the Executive, and shall credit the account with
contributions and earnings and debit the account for distributions, as described
in this Plan.

3.       CONTRIBUTIONS. Stillwater National shall make contributions to the Plan
Account as follows:

         (a)      Supplemental Profit Sharing Contributions. Stillwater National
                  shall credit the Plan Account with the amount equal to the
                  difference between the aggregate amount of contributions which
                  would have been allocated with respect to the Executive under
                  the Profit Sharing Plan based on the Executive's Compensation
                  without regard to the limitations imposed by the Code on the
                  Profit Sharing Plan, or otherwise contained in the Plan, and
                  the aggregate amount of contributions actually made with
                  respect to the Executive, without regard to forfeitures. For
                  purposes of determining the amount which would have been
                  allocated to the Profit Sharing Plan, such amount shall be
                  deemed to be proportionate to the ratio of the actual
                  contribution made to such plan over the compensation taken
                  into account under such plan. Such contributions shall be
                  credited to the Plan Account at substantially the same time as
                  contributions are made to the Profit Sharing Plan. Stillwater
                  National is not required to make any Supplemental Profit
                  Sharing Contribution for any period in which it does not make
                  a contribution to the Profit Sharing Plan. No Supplemental
                  Profit Sharing Contributions shall be made following a
                  termination of the Executive's employment for Cause or
                  voluntary termination without Good Reason. The Supplemental
                  Profit Sharing Contribution for the calendar year in which the
                  Executive's or his Beneficiary's rights under the Plan vest
                  shall be prorated based upon the number of days in the
                  calendar year prior to the vesting date over 365.

         (b)      Discretionary Contributions. Stillwater National may make, but
                  is not required by this Plan to make, additional,
                  discretionary contributions to the Plan Account at such times
                  and in such amounts as it may deem appropriate.

         (c)      Earnings Until the Plan Account is fully distributed to the
                  Executive or his Beneficiary, the Plan Account shall be
                  credited as of the last day of each calendar quarter with
                  earnings as though the balance of the Plan Account at the
                  beginning of such calendar quarter were invested in an
                  uninsured, nondeposit fund account having an annual return for
                  each calendar quarter equal to the annualized average interest
                  rate earned (non-taxable equivalent) by Stillwater National on
                  average interest-earning assets for such calendar quarter, and
                  except as provided in Section 6 hereof, as calculated in good
                  faith by Stillwater National. (For example, the earnings rate
                  for the first calendar quarter of 2002 would have been 6.65%,
                  if the Plan were then in effect.)

         (d)      Unfunded Arrangement. The parties intend that this Plan be
                  unfunded for purposes of ERISA and the Code. The Executive and
                  his Beneficiary are general unsecured creditors of Stillwater
                  National for the payment of benefits under this Plan. The
                  benefits represent the mere promise by Stillwater National to
                  pay such benefits. The rights to benefits are not subject in
                  any manner to anticipation, alienation, sale, transfer,
                  assignment, pledge, encumbrance, attachment, or garnishment by
                  creditors of the Executive or his Beneficiary. Any
                  representation or assertion contrary to this section 3(d) is a
                  material breach of this Plan by the representing or asserting
                  party, which, if such party is the Executive or, following his
                  death, a Beneficiary, shall immediately result in the
                  cessation of any and all payments and the elimination of any
                  liability hereunder for any payment not made prior to such
                  assertion or representation, and, if such party is Stillwater
                  National or an Affiliate of Stillwater National, shall subject
                  Stillwater National to liability for actual damages for such
                  breach.

                  choices offered below, by written notice to Stillwater
                  National. The Executive, pursuant to the Plan, hereby elects

                  earnings distributed as follows:

                                  [Choose One]

                  distributed to the Participant's Beneficiary in accordance
                  with the method selected by the Executive. If a Participant

                  Beneficiary is living on the date of distribution, such amount
                  shall be distributed to those persons or such trust entitled
                  to receive distributions of the Executive's benefits under the
                  Profit Sharing Plan.

         (f)      Emergency Distributions. In the event the Executive incurs an
                  unforeseeable emergency, the Executive may make a written
                  request to the Stillwater National for a hardship withdrawal
                  from his or her account. An unforeseeable emergency is a
                  severe financial hardship to the Executive resulting from a
                  sudden and unexpected illness or accident of the Executive or
                  of a dependent (as defined in Section 152(a) of the Code),
                  loss of the Executive's property due to casualty, or other
                  similar extraordinary and unforeseeable circumstances arising
                  as a result of events beyond the control of the Executive.
                  Withdrawals of amounts because of an unforeseeable emergency
                  are only permitted to the extent reasonably needed to satisfy
                  the emergency need. This section shall be interpreted in a
                  manner consistent with Sections 1.457-2(h)(4) and
                  1.457-2(h)(5) of the Treasury Regulations.

5.       PLAN ADMINISTRATION.

         (a)      Committee. The Plan shall be administered by the Committee. In
                  the absence at any time of a duly appointed Committee, the
                  Plan shall be administered by the Board. Except as limited by
                  the express provisions of the Plan or by resolutions adopted
                  by the Board, the Committee shall have sole and complete
                  authority and to prescribe, amend and rescind rules and
                  regulations relating to the Plan, and to make other
                  determinations necessary or advisable for the administration
                  of the Plan. The Committee shall have and may exercise such
                  other power and authority as may be delegated to it by the
                  Board from time to time.

         (b)      Indemnification and Limitation of Liability. In addition to
                  such other rights of indemnification as they may have, the
                  members of the Committee shall be indemnified by Stillwater
                  National in connection with any claim, action, suit or
                  proceeding relating to any action taken or failure to act
                  under or in connection with the Plan to the maximum extent
                  provided for under Stillwater National's Certificate of
                  Incorporation or Bylaws with respect to the indemnification of
                  Directors. Stillwater National nor any of its officers,
                  directors, Affiliates, or agents shall be liable to the
                  Executive, his Beneficiary or any other person for any claim,
                  loss, liability or expense incurred in connection with the
                  Plan, unless attributable to fraud or willful misconduct on
                  the part of such person.

         (c)      Costs and Statements. Stillwater National shall pay the
                  expenses of administration and the costs of employing
                  employment counsel and accountants with respect to the Plan or
                  its administration, including without limitation, the
                  administrative and other costs of the Trust. Stillwater
                  National shall furnish individual annual statements of accrued
                  benefits to the Executive or current Beneficiary, in such form
                  as determined by Stillwater National or as required by law.

         (d)      Facility of Payment. If a benefit is payable to a minor, to a
                  person declared incompetent, or to a person incapable of
                  handling the disposition of his or her property, Stillwater
                  National may pay such benefit to the guardian, legal
                  representative, or person having the care or custody of such
                  minor, incompetent person, or incapable person. Stillwater
                  National may require proof of incompetency, minority, or
                  guardianship as it may deem appropriate prior to the
                  distribution of the benefit. Such distribution shall
                  completely discharge Stillwater National from all liability
                  with respect to such benefit.

6.       TRUST. Prior to or simultaneously with any Transaction and within ten
calendar days of any other Change in Control, unless and to the extent the
Executive has previously provided a written release of any claims under this
Plan, Stillwater National shall establish a valid trust under the law of the
State of Oklahoma with an independent trustee that has or may be granted
corporate trust powers under Oklahoma law, deposit in such trust an amount equal
to 200% of the Plan Account balance immediately prior to the establishment of
the Trust, and provide the Trustee of the Trust with a written direction to
invest such amount in securities supported by the full faith and credit of the
United States except for amounts held in one or more deposit accounts as needed
on a short-term basis to pay amounts due to the Executive or his Beneficiary as
provided below, to hold said amount and any investment return thereon in a
segregated account, and to pay such amounts due to the Executive (or upon his
death, his Beneficiary) under this Plan. Upon the final payment of all amounts
due to the Executive or his Beneficiary under this Plan, the Trustee of the
Trust shall pay to Stillwater National the entire balance, if any, remaining in
the Trust. Payments from the Trust to the Executive shall be considered payments
made by Stillwater National for purposes of this Agreement. Payment of such
amounts to the Executive from the Trust, however, shall not relieve Stillwater
National from any obligation to pay amounts in excess of those paid from the
Trust, or from any obligation to take actions or refrain from taking actions
otherwise required by this Plan. In no event may the Trust invest in securities
or obligations issued by Stillwater National or any of its Affiliates or
successors. Stillwater National shall have no right or power to direct the
Trustee to return or divert any of the Trust assets before all payments of
benefits have been made. Stillwater National shall pay all fees and expenses of
the Trust, including, without limitation, Trustee fees, and all income taxes on
earnings of the Trust from its assets outside of the Trust. In the event that
Stillwater National shall not provide the earnings rate referred to under
Section 3(c) hereof, the Trustee shall calculate such rate based upon reports of
condition furnished by Stillwater National to its primary federal banking
regulator or upon other publicly available reports. The Executive's and his
Beneficiary's rights under this Plan shall be those of a general, unsecured
creditor, he shall have no claim against the assets of the Trust, and the assets
of the Trust shall be considered general assets of Stillwater National subject
to the claims of creditors of Stillwater National in the event of its bankruptcy
or insolvency.

7.       NO EFFECT ON PROFIT SHARING PLAN. This Plan has no effect upon benefits
under or the terms of the Profit Sharing Plan.

8.       FORFEITURE OR SUSPENSION OF PLAN BENEFITS.

         (a)      In General. The Executive shall completely forfeit any and all
                  rights to any and all benefits under this Plan upon his
                  termination for Cause or his voluntary termination without
                  Good Reason.

         (b)      Competition. Regardless of anything herein to the contrary,
                  except in the case of a termination of employment by
                  Stillwater National without Just Cause, a termination of
                  employment by the Executive with Good Reason, or with the
                  permission of Stillwater National, if the Executive shall,
                  during the two years immediately following the Executive's
                  termination of employment, serve as an officer or director or
                  employee of any bank holding company, bank, savings
                  association, savings and loan holding company, or mortgage
                  company (any of which, a "Financial Institution") which
                  Financial Institution offers products or services competing
                  with those offered by the Bank from offices in any county in
                  the Primary Market Area, or shall interfere with the
                  relationship of Stillwater National and any of its employees,
                  agents, or representatives, then the Committee shall direct
                  that any unpaid balance of any payments to the Executive under
                  this Agreement be suspended, and shall thereupon notify the
                  Executive of such suspension, in writing. Thereupon, if the
                  Committee shall determine that such behavior by the executive
                  exists at any time after a period of one month following
                  notification of such suspension, all rights of the Executive
                  and his Beneficiary under this Plan, including rights to any
                  and all further payments hereunder, shall thereupon terminate.

         (c)      Certain Regulatory Events. If the Executive is removed and/or
                  permanently prohibited from participating in the conduct of
                  Stillwater National's affairs by an order issued under
                  Sections 8(e)(4) or 8(g)(1) of the Federal Deposit Insurance
                  Act ("FDIA") (12 U.S.C. ss.ss. 1818(e)(4) and (g)(1)), all
                  obligations of Stillwater National under this Agreement shall
                  terminate as of the effective date of the order, but vested
                  rights of the parties shall not be affected. If Stillwater
                  National is in default (as defined in Section 3(x)(1) of
                  FDIA), all obligations of Stillwater National under this
                  Agreement shall terminate as of the date of default, but
                  vested rights of the parties shall not be affected. If a
                  notice served under Sections 8(e)(3) or (g)(1) of the FDIA (12
                  U.S.C. ss.ss. 1818(e)(3) and (g)(1)) suspends and/or
                  temporarily prohibits the Executive from participating in the
                  conduct of Stillwater National's affairs, Stillwater
                  National's obligations under this Agreement shall be suspended
                  as of the date of such service, unless stayed by appropriate
                  proceedings. If the charges in the notice are dismissed,
                  Stillwater National may, in its discretion, (i) pay the
                  Executive all or part of the contributions or payments
                  withheld while its contract obligations were suspended, and
                  (ii) reinstate (in whole or in part) any of its obligations
                  which were suspended.

9.       TERMINATION. Stillwater National may terminate this Plan only upon
termination of the Profit Sharing Plan or with the Agreement of the Executive.
No termination of the Plan shall directly or indirectly reduce the balance of
the Plan Account as of the effective date of such termination. Upon termination
of the Plan, distribution of the Plan Account in accordance with Section amounts
credited to such account shall be made to the Executive or his or her
Beneficiary in accordance with Section 4. No contributions will be credited to
the Plan Account after termination of the Plan, but earnings will continue to be
credited to the Plan Account until all amounts are distributed to the Executive
or his Beneficiary.

10.      GOVERNING LAW. The Plan shall be governed by and construed in
accordance with the laws of the State of Oklahoma, except to the extent that
federal law shall be deemed to apply.

11.      SUCCESSORS AND ASSIGNS. The Plan shall be binding upon Stillwater
National's successors

12.      AMENDMENTS. No amendments or additions to this Plan shall be binding
unless made in writing and signed by all of the parties, except as herein
otherwise specifically provided.

13.      SEVERABILITY. The provisions of this Agreement shall be deemed
severable and the invalidity or unenforceability of any provision shall not
affect the validity or enforceability of the other provisions hereof.

14.      HEADINGS. Headings contained herein are for convenience of reference
only.

15.      AMERICAN JOBS CREATION ACT COMPLIANCE. The parties hereto intend that
this Plan shall comply in all respects with Section 409A of the Internal Revenue
Code as added by the American Jobs Creation Act of 2004 and related Internal
Revenue Service regulations and procedures (together ss.409A"). Accordingly, any
term of this Plan that conflicts with ss.409A shall be amended to the extent
necessary to remove such conflict (or shall be removed if necessary to comply
with ss.409A) and any provision required by ss.409A shall be added, effective as
of the date of this Agreement. It is the intent of the parties hereto that this
Plan will be restated to reflect any such amendments or additions within a
reasonable period following the publication of applicable final regulations and
procedures by the Internal Revenue Service. This section shall not be deemed to
amend Plans entered prior to the date hereof.

16.      ENTIRE AGREEMENT. This Agreement, together with any understanding or
modifications thereof as agreed to in writing by the parties, shall constitute
