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 earnings per share and assets of 10% and
geographic market share growth and expansion," said Rick Green, President and
Chief Executive Officer. "Southwest's earnings growth 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."

         "In 2003, Southwest achieved net income of $14.9 million and increased
diluted earnings per share by 10% over the same period last year. We acted
aggressively to resolve problem credits during the fourth quarter, reducing
nonperforming loans by 17% from $19.2 million at the end of the third quarter to
$15.9 million at year-end."

         "During 2002, Southwest made strategic moves into two important markets
- - a branch in Dallas, Texas and a loan production office in Wichita, Kansas,
both of which operated as divisions of Stillwater National Bank and Trust
Company. In November 2003, the Wichita loan production office was replaced by a
new Southwest subsidiary, SNB Bank of Wichita. The Dallas and Wichita offices
are capitalizing on our strengths in serving medical, professional and small
business customers. We are pleased with our continuing significant loan growth
in both markets. Our experience there demonstrates our ability to select new
markets and to successfully implement our business plan in them."

         "We continue to market and find acceptance for our "Business Mail
Processing" and "Document Imaging" services, especially in our metropolitan
markets. These products are contributing to our success in gaining
noninterest-bearing demand deposits and should continue to help differentiate
Southwest from other financial services companies."

         "In the second quarter of 2003, Southwest issued $20.0 million in trust
preferred securities through a newly formed subsidiary trust, OKSB Statutory
Trust I, in a private placement of pooled trust preferred securities. The
majority of the proceeds of the private placement were contributed to Stillwater
National; $6.0 million of the remaining proceeds were contributed to SNB Bank of
Wichita upon organization. On October 14, 2003, Southwest issued an additional
$25.0 million of 30-year variable rate trust preferred securities in a private
placement through another subsidiary trust, SBI Capital Trust II. Proceeds from
the October issuance are expected to be used to retire the $25.0 million in
9.30% fixed rate trust preferred securities issued in 1997, which became subject
to redemption by Southwest in the third quarter of 2002. Although the redemption
would result in a charge to expense of approximately $650,000, net of tax
benefit, upon retirement, management estimates that the redemption would have a
net positive effect on net income within twelve months from redemption and
thereafter. Whether or not Southwest redeems the 1997 trust preferred securities
during


                                  Page 2 of 2





2004 depends upon a number of factors, including the currently unsettled
regulatory capital rules relating to trust preferred securities as a result of
recent changes in accounting standards. Due to these recent changes in
accounting standards, the Trust Preferred Securities are not carried on
Southwest's consolidated financial statements. Instead, Southwest's financial
statements reflect the Subordinated Debentures issued by Southwest to the
subsidiary trusts which provided the funding for the Trust Preferred
Securities."

         "At year-end 2003, Southwest had total assets of $1.6 billion, loans of
$1.3 billion, and deposits of $1.2 billion. At that date, the allowance for loan
losses was $15.8 million, or 1.21% of total loans, compared to $11.9 million, or
1.08% of total loans, at year-end 2002. At the end of 2003, regulatory capital
ratios for Southwest, Stillwater National, and SNB Wichita exceeded regulatory
requirements for a well-capitalized institution."

ADDITIONAL FINANCIAL INFORMATION

         Net income for 2003 was $14.9 million, up $1.5 million, or 11%, from
2002. Diluted earnings per share for 2003 were $1.22, up 10% from 2002.

         Net interest income increased 21% from 2002. Non-interest income for
2003 represented 21% of total revenues.

         The provision for loan losses of $8.5 million increased $3.1 million,
or 57%, over 2002. Noninterest expense of $38.4 million increased $5.1 million,
or 15%, primarily as a result of increases in compensation, general and
administrative, and occupancy expenses.

         Net income for the fourth quarter of 2003 was $3.9 million, a $434,000,
or 12%, increase from the fourth quarter of 2002. Diluted earnings per share of
$0.32 for the fourth quarter of 2003 increased 10% from the fourth quarter of
2002.

         Net interest income increased 26% from the fourth quarter of last year.
Non-interest income for the quarter represented 20% of total revenues.

         The provision for loan losses of $2.1 million increased $726,000, or
54%, over the 2002 fourth quarter. Noninterest expense of $10.4 million
increased $1.4 million, or 15%, primarily as a result of increases in
compensation, general and administrative, and occupancy expenses. The efficiency
ratio of 56.57% represented an improvement of 189 basis points from the fourth
quarter of 2002. Southwest's efficiency ratio is based directly on financial
statement amounts.

FINANCIAL CONDITION

         At December 31, 2003, total assets were $1.6 billion, a $230.2 million
increase from the end of 2002. Total portfolio loans (loans other than those
held for sale) at year-end 2003 were $1.3 billion, up $211.5 million, or 19%,
from year-end 2002, primarily as a result of growth in commercial and
construction lending, as well as government-guaranteed student loans.

ALLOWANCE FOR LOAN LOSSES AND NONPERFORMING LOANS

         Nonaccrual loans totaled $14.5 million at December 31, 2003, compared
to $17.0 million at September 30, 2003. This $2.5 million reduction is primarily
the result of several large problem credits classified as nonaccrual at
September 30, 2003, that were resolved during the fourth quarter of 2003; $1.4
million in nonaccrual loans were returned to accrual status and $1.7 in
nonaccrual loans were transferred to Other Real Estate. Total nonperforming
loans of $15.9 million increased $3.0 million, or 23%, from year-end 2002, and
represented 1.22% of loans, compared to 1.17% of loans at year-end 2002 and
1.50% of loans at September 30, 2003. At December 31, 2003, $2.7 million, or
17%, of loans classified as nonperforming were guaranteed by United States
agencies or U.S. government sponsored entities.

         Mr. Green said, "Much of our business is commercial lending. As a
result, weakness in one or a few large credits can have a significant impact on
our nonperforming loan totals. Through the years, however, we have demonstrated
the ability to resolve problem commercial loans."

         The allowance for loan losses of $15.8 million increased $4.0 million,
or 33%, from year-end 2002, due primarily to the $207.7 million growth in loans
that occurred during the year. Management believes the amount of the allowance
is appropriate, given its 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.

(1)     The net interest margin is equal to annualized net interest income
        divided by average interest-earning assets.

(2)     In order to make pretax income and resultant yields on tax-exempt
        investments and loans comparable to those on taxable investments and
        loans, a tax equivalent adjustment is made equally to interest income
        and income tax expense with no effect on after tax income.
        The tax equivalent adjustment has been computed using a federal income
        tax rate of 35%.
