Item 9. Regulation FD Disclosure.
--------------------------------

         Southwest Bancorp, Inc., financial holding company for Stillwater
National Bank & Trust Company, today announced that Rick Green, President and
Chief Executive Officer, plans to sell a portion of his holdings of Southwest
common stock in order to diversify his holdings for estate and retirement
planning purposes. Mr. Green stated that his decision to sell was based solely
upon his need to reduce the substantial concentration of his assets in Southwest
common stock, and expressed his continued confidence in Southwest Bancorp. Mr.
Green has no current plans to retire.

         Mr. Green plans to sell from approximately 45,000 to 75,000 shares
within calendar year 2003. This number of shares is less than 2.0% of
outstanding common shares. Most or all of the shares sold sales will be acquired
in 2003 upon the exercise of previously granted stock options that expire in
2004. Mr. Green has indicated that he also currently expects to sell an
undetermined number of additional shares during 2004 and later years in
connection with his estate and retirement planning. The shares will be sold from
time to time in market or private transactions and subject to pre-determined
price thresholds and certain other contingencies. Sales will generally be made
during the 10-day period beginning on the second day following the issuance of
earnings releases or the filing of annual or quarterly reports on Form 10-K or
Form 10-Q, although Mr. Green reserves the right to sell at other times. Other
executive officers also are expected to sell shares acquired upon the exercise
of previously granted options during 2003 and 2004.

         This Form 8-K contains forward-looking statements that are based upon
the current beliefs and expectations of Southwest and Mr. Green and are subject
to significant risks and uncertainties. These statements include statements
regarding: (1) the impact of sales of Southwest's stock by Mr. Green and other
executive officers on Southwest's market price; and (2) Southwest's expectations
regarding the timing and manner of sales of stock by Mr. Green and other
executive officers. Actual results may differ from those set forth in the
forward-looking statements. The following factors, among others, could cause
actual results to differ materially from the anticipated results or other
expectations expressed in such forward-looking statements: (1) volatility in
Southwest's stock price; (2) termination or modification of Mr. Green's plans;
(3) adverse conditions and volatility in the stock market, the public debt
market and other capital markets; and (4) changes in state or federal income or
estate tax laws. Pursuant to General Instruction B.2. to Form 8-K, the
information in this report shall not be deemed to be filed for the purposes of
Section 18 of the Exchange Act or otherwise subject to the liabilities of that
section.

         Pursuant to the requirements of the Securities Exchange Act of 1934,

undersigned hereunto duly authorized.
