Southwest Bancorp Results: Portfolio Loans up 10% since Year End

     July 19, 2007, Stillwater, Oklahoma . . . . Southwest Bancorp, Inc. (Nasdaq Global Select Market—OKSB), (“Southwest”), today reported net income for the second quarter of 2007 of $6.8 million, a 3% increase from the $6.6 million reported for the second quarter of 2006. Diluted earnings per share for the quarter were $0.47 compared to $0.45 per share for the 2006 period, an increase of 4%. Net income for the first six months of 2007 was $11.3 million, a 12% decrease from the $12.9 million reported for the first six months of 2006. Diluted earnings per share were $0.78 compared to $0.89 per share for the 2006 period, a decrease of 13%. Income for the second quarter 2007 reflects a $1.9 million pre-tax gain on the sale of shares received in a debt restructuring, while the income for the first six months reflects a one time $2.5 million pre-tax write off of a cash receivable and related year to date legal fees of approximately $500,000.

     Rick Green, President and Chief Executive Officer, stated, “We continue to pursue our long-range strategies for growth and market expansion. At June 30, 2007, our Texas and Kansas operations accounted for $833.2 million, (47%) of total portfolio loans and had grown $143.4 million (21%) since year end 2006. The total $166.8 million (10%) growth in portfolio loans year to date more than offset the decreases in secondary market (which includes student lending). Student lending at quarter end represented only 4% of our total loans, down from 10% at year end 2006 and 18 % of total loans at June 30 of last year. Core deposits (all deposits other than large time deposits) grew by $135.1 million (12%) in the first six months of 2007.

     “We also are glad to report that sub prime lending has never been a part of our business strategy, and that our sub prime loan exposure is minimal to none.”

Highlights (Preliminary)

•   Second quarter net income:	$6.8 million, a 3% increase from second quarter 2006
•   Portfolio loans:	$1.8 billion, a 10% increase from year end 2006
•   Total loans:	$1.8 billion, a 3% increase from year end 2006
•   Return on average equity:	13.26% for the second quarter 2007
	11.19% for the six months ending June 30, 2007
•   GAAP-based efficiency ratio:	52.82% for the second quarter 2007
	58.49% for the six months ending June 30, 2007

(Please see Financial Tables 1 through 7 for additional financial information.)

Preliminary Results of Operations

     The $215,000, or 3% increase in quarterly net income from second quarter 2006 was the result of a $1.2 million (36%) decrease in provision for loan losses and a $949,000 (21%) increase in noninterest income, offset in part by a $278,000 (1%) decrease in net interest income, a $709,000 (20%) increase in income taxes and a $956,000 (7%) increase in noninterest expense.

NASDAQ: OKSB

Southwest Bancorp Results: Portfolio Loans up 10% since Year End

     The $278,000 decrease in net interest income for the quarter was primarily the result of increased loan yields offset by higher rates on interest bearing deposits. The ratio of our allowance for loan losses to total loans at quarter end was 1.52%, unchanged from year end 2006. The increase in other income was mainly the result of a gain of $1.9 million on the sale of 1,500,000 shares of common stock of a public corporation offset in part by substantially lower gains on the sale of student and other loans. The quarterly efficiency ratio was at a favorable 53% level.

     The $1.6 million, or 12% decrease in net income for the six months ending June 30, 2007 compared to the six months ending June 30, 2006 was the result of a $194,000 (less than 1%) increase in net interest income, a $2.0 million (34%) decrease in the provision for loan losses, an increase in noninterest income of $321,000 (4%) and a $494,000 (6%) decrease in income taxes, offset by a $4.6 million (17%) increase in noninterest expense.

Financial Condition

     At June 30, 2007, total assets were $2.2 billion, a $25.4 million, or 1% increase from December 31, 2006. Shareholders’ equity at June 30, 2007 totaled $208.2 million, an $10.7 million, or 5%, increase from year end 2006. Core deposits grew by $135.1 million, or 12%, in the first half of the year. Consistent with our earlier disclosures, student lending balances have decreased from year end 2006 and are expected to continue to decrease.

     Portfolio loans increased by $166.8 million, or 10% during the first six months of 2007. Portfolio loans exclude loans held for sale. Southwest’s growth in portfolio loans more than offset the expected reduction in loans held for sale, almost all of which are student loans.

     In the last twelve months, Southwest’s Texas and Kansas offices have increased total portfolio loans $219.6 million. At June 30, 2007, Southwest’s seven Texas and two Kansas offices accounted for $833.2 million in loans, or 47% of total portfolio loans, up from 43% at December 31, 2006. Southwest expects to open additional offices in Texas and Kansas in the months ahead.

     At June 30, 2007, the allowance for loan losses was $28.1 million, an increase of $761,000, or 3%, from the allowance for loan losses at December 31, 2006. This change is the result of growth in performing commercial and commercial real estate loans and an increase in potential problem loans offset in part by decreases in the allowance related to impaired loans and the general allowance. At June 30, 2007, the allowance for loan losses was 1.52% of total loans, unchanged from year end 2006. Management believes the amount of the allowance is appropriate, given its systematic methodology for calculating the allowance. Changes in the amount of the allowance resulted from the application of that methodology, which is designed to estimate inherent losses on total loans in the portfolio, including those on nonperforming loans.

     At June 30, 2007, the reserve for unfunded loan commitments was $2.0 million, an increase of $86,000, or 4%, from December 31, 2006 due to an increase in commitments, partially offset by a substantial decrease in the reserve on commitments related to potential problem loans.

     Nonaccrual loans totaled $22.6 million at June 30, 2007, compared to $26.7 million at December 31, 2006. Total nonperforming loans of $24.3 million decreased $5.1 million, or 17% from year end 2006, and represented 1.32% of total loans, compared to 1.64% of total loans at year end 2006. The decrease in nonperforming loans is due primarily to one relationship returning to accrual status. At June 30, 2007, $1.3 million, or 5%, of loans classified as nonperforming were guaranteed by United States agencies or U.S. government sponsored entities.

     Other real estate at June 30, 2007, was $1.5 million, a reduction of $365,000, or 19% from December 31, 2006. Total nonperforming assets at June 30, 2007, were $25.8 million, a decrease of $5.5 million, or 17% from December 31, 2006.

     Performing loans considered potential problem loans, loans which are not included in the past due, nonaccrual, or restructured categories, but for which known information about possible credit problems cause management to be uncertain as to the ability of the borrowers to comply with the present loan repayment terms, amounted to approximately $69.6 million at June 30, 2007, compared to $50.6 million at December 31, 2006, a 38% increase.

Cash Receivable

     As previously disclosed, in December 2006, an armored transportation company failed to deliver to Stillwater National Bank and Trust (“Stillwater National”) cash due to it from certain ATMs owned by one of its subsidiaries, Cash Source, Inc. (“CSI”). CSI discovered other cash shortages arising from the same transportation company and has removed all cash from the other CSI ATMs for which that company provided cash transportation.

     Southwest has estimated the loss as the total amount of the receivable, and has recorded a complete write-off of that amount as reflected in the financial statements for the first quarter of 2007. The financial statements also reflect related legal expenses incurred by Southwest in 2007 of approximately $500,000. Southwest continues to vigorously pursue its investigation and efforts to recover the missing cash or otherwise mitigate its damages. Southwest is in the process of preparing its claim for insurance, which it intends to file in the third quarter of 2007.

Southwest Bancorp and Subsidiaries

     Southwest Bancorp is the financial holding company for Stillwater National, SNB Bank of Wichita (“SNB Wichita”), Healthcare Strategic Support, Inc., and Business Consulting Group, Inc. Through its subsidiaries, Southwest offers commercial and consumer lending, deposit, and investment services, and specialized cash management, consulting, and other financial services from offices in Oklahoma City, Stillwater, Tulsa, and Chickasha, Oklahoma; Austin, Dallas, Houston and San Antonio, Texas; and Kansas City and Wichita, Kansas, and on the Internet, throughSNB DirectBanker^®.

     Southwest focuses on converting its strategic vision into long-term shareholder value. This vision includes long-term goals for increasing earnings and banking assets from operations in Oklahoma, Texas, and Kansas that specialize in serving medical, professional, business, and commercial real estate customers and from more traditional banking operations, such as community banking. Southwest’s strategic growth goals include growth from existing and additional offices in carefully selected markets in Texas and other states with concentrations of healthcare and health professionals, businesses, and their managers and owners, and commercial and commercial real estate borrowers, and careful expansion of community banking operations.

     On February 2, 2007, Southwest signed an agreement to purchase the Bank of Kansas for a cash price of $15.25 million. Bank of Kansas has total assets of approximately $76 million, loans of approximately $42 million, deposits of approximately $68 million, and two banking offices in the Hutchinson, Kansas market. This transaction has received the required bank regulatory approvals and is expected to close in the third quarter of 2007.

     Southwest’s banking philosophy is to provide a high level of customer service, a wide range of financial services, and products responsive to customer needs with a focus on serving healthcare and health professionals, businesses and their managers and owners, and commercial and commercial real estate borrowers. This philosophy has led to the development of a line of deposit, lending, and other financial products that respond to professional and commercial customer needs for speed, efficiency, and information, and which complement more traditional banking products. Southwest seeks to build close relationships with businesses, professionals and their principals, and to service their evolving banking needs throughout their business development and professional lives.

     Southwest has developed a highly automated lockbox, imaging, and information service for commercial customers called “SNB Digital Lockbox” and deposit products that automatically sweep excess funds from commercial demand deposit accounts and invest them in interest bearing funds. Other specialized financial services include integrated document imaging and cash management services designed to help our customers in the healthcare industry and other record-intensive enterprises operate more efficiently.

     Southwest’s two management consulting subsidiaries complement its banking services and help differentiate Southwest from competitors. Healthcare Strategic Support, Inc. provides management consulting services for physicians, hospitals, and healthcare groups. Business Consulting Group, Inc. provides marketing, strategic, logistics, and operations consulting for both small and large commercial enterprises.

     Southwest’s common stock is traded on the NASDAQ Global Select Market under the symbol OKSB.
