STRATEGIC PERSPECTIVE

         "Southwest Bancorp, Inc. ("Southwest") maintains an intense focus on
specific performance goals designed to increase shareholder value. These goals
include annual growth in diluted EPS and assets of 10% and geographic market
share growth and expansion," said Rick Green, President and Chief Executive
Officer. "In the first quarter of 2003, Southwest achieved net income of $3.5
million and increased earnings per share by 12% over the first quarter of last
year. This represents the fourth consecutive quarter of record earnings. At
quarter-end, Southwest's total assets were $1.5 billion."




         "Our performance is primarily the result of substantial loan growth,
increases in net interest and noninterest income, and improved efficiency. We
are continuing to focus on increasing net interest income by prudent loan growth
coupled with careful management of interest margins and funding."

         "During 2002, we made strategic moves into two important markets -
Dallas, Texas and Wichita, Kansas. These offices are capitalizing on our
strengths in serving medical, professional and small business customers. We were
pleased with our significant loan growth from these new markets, and expect
continued growth in both locations. Our traditional markets, particularly the
Oklahoma City and Tulsa divisions and our Student Lending division, also
contributed significantly to the overall loan growth in the quarter."

         "During the first quarter of 2003, we established the Healthcare
Strategies Group, a consulting organization which assists the healthcare
industry with a focus on the needs of regional and community hospitals, surgery
centers, and specialty and medical group practices. The services offered by this
group of experienced and noted professionals are a natural complement to our
core health care services."

         "Business Consulting Group, Inc., a subsidiary of the Company founded
in early 2002, is specifically focused on identifying alternatives for each
customer to enhance the performance of his or her own company. Its professional
staff has years of success in providing consulting services in the private and
public sectors."

ADDITIONAL FINANCIAL INFORMATION

         Net income for the first quarter of 2003 was $3.5 million (up $435,000,
or 14.1%, from the first quarter of 2002), and marked Southwest's fourth
consecutive quarter of record earnings. Diluted earnings per share for the first
quarter of 2003 increased to $0.58, up 11.5% from the first quarter of 2002.

         Net interest income was up 13.9% from the first quarter of last year.
Non-interest income for the quarter represented 21.6% of total revenues.

         The provision for loan losses of $1.7 million increased $472,000, or
38%, over the 2002 first quarter. Noninterest expense of $8.9 million increased
$1.1 million, or 14%, primarily as a result of increases in compensation,
general and administrative, and occupancy expenses. The efficiency ratio of
55.38% represented an improvement of 159 basis points from the first quarter of
2002. Southwest's efficiency ratio is based directly on financial statement
amounts.





FINANCIAL CONDITION

         At March 31, 2003, total assets were $1.5 billion, a $136.3 million
increase from the end of 2002 and a $266.9 million increase from March 31, 2002.
Total portfolio loans (loans other than those held for sale) at March 31, 2003
were $1.2 billion, up $129.8 million, or 11.9%, from year-end 2002 and up $273.8
million, or 28.9%, from March 31, 2002, primarily as a result of growth in
commercial and commercial real estate lending, as well as government guaranteed
student loans.

         The allowance for loan losses of $13.2 million increased $1.3 million,
or 10.6%, from year-end 2002. Total nonperforming loans of $14.6 million
increased $1.7 million, or 13.5%, from year-end 2002, and represented 1.19% of
loans, compared to 1.17% of loans at year-end 2002. At March 31, 2003, $1.5
million, or 10.5%, of loans classified as nonperforming were guaranteed by
United States agencies or U.S. government sponsored entities. Management
believes the amount of the allowance is appropriate, given the systematic
methodology for calculating the allowance. That methodology is designed to
estimate inherent losses on total loans in the portfolio, including inherent
losses on nonperforming loans.

         At March 31, 2003, regulatory capital ratios for Southwest and its
banking subsidiary, Stillwater National Bank and Trust Company, exceeded all
regulatory requirements for a well-capitalized institution.
