             Notes to Unaudited Consolidated Financial Statements


NOTE 1:   GENERAL

The accompanying unaudited consolidated financial statements were prepared in
accordance with instructions for Form 10-Q and, therefore, do not include all
information and notes necessary for a complete presentation of financial
position, results of operations, changes in shareholders' equity, cash flows and
comprehensive income in conformity with generally accepted accounting
principles.  However, the consolidated financial statements include all
adjustments (consisting only of normal recurring accruals) which, in the opinion
of management, are necessary for a fair presentation.  The results of operations
and cash flows for the six months ended June 30, 1999 and 1998 should not be
considered indicative of the results to be expected for the full year.  These
consolidated financial statements should be read in conjunction with the
consolidated financial statements and notes thereto included in the Southwest
Bancorp, Inc. Annual Report on Form 10-K for the year ended December 31, 1998.


NOTE 2:   PRINCIPLES OF CONSOLIDATION

The accompanying unaudited consolidated financial statements include the
accounts of Southwest Bancorp, Inc. ("Southwest") and its wholly owned
subsidiaries, the Stillwater National Bank and Trust Company ("Stillwater
National") and SBI Capital Trust ("SBI Capital").  All significant intercompany
transactions and balances have been eliminated in consolidation.


NOTE 3:   ACCOUNTING STANDARD ISSUED BUT NOT YET ADOPTED

In June 1998, the FASB issued SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities.  SFAS No. 133 establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts, (collectively referred to as
derivatives) and for hedging activities.  It requires that Southwest recognize
all derivatives as either assets or liabilities in the statement of financial
condition and measure those instruments at fair value.  The accounting for
changes in the fair value of a derivative (that is, gains and losses) depends on
the intended use of the derivative and the resulting designation.  Southwest
will adopt SFAS No. 133 on January 1, 2001, as required.  Management believes
that adoption of SFAS No. 133 will not have a material impact on Southwest's
consolidated financial condition or results of operations.

(1)  The government-guaranteed portion of loans included in these totals was
     $684 (1999) and $254 (1998).

Southwest makes provisions for loan losses in amounts deemed necessary to
maintain the allowance for loan losses at an appropriate level.  The adequacy of
the allowance for loan losses is determined by management based upon a number of
factors including, among others, analytical reviews of loan loss experience in
relation to outstanding loans and commitments; unfunded loan commitments;
problem and nonperforming loans and other loans presenting credit concerns;
trends in loan growth, portfolio composition and quality; use of appraisals to
estimate the value of collateral; and management's judgment with respect to
current and expected economic conditions and their impact on the existing loan
portfolio.  Changes in the allowance may also occur because of changing economic
conditions and their impact on economic prospects and the financial position of
borrowers.  Based upon this review, management established an allowance of $10.9
million, or 1.39% of total loans, at June 30, 1999 compared to an allowance of
$10.4 million, or 1.31% of total loans, at December 31, 1998.

In establishing the level of the allowance for June 30, 1999, management
considered a number of factors, including the increased risk inherent in
commercial and commercial real estate loans, which are viewed as entailing
greater risk than certain other categories of loans, charge-off history, and the
rapid expansion of the loan portfolio over the last several years.  Management
also considered other factors, including the levels of types of credits, such as
residential mortgage loans, deemed to be of relatively low risk.  Southwest
determined the level of the allowance for loan losses at June 30, 1999 was
appropriate, after assessing these and other factors it deemed relevant.
Management conducted a similar analysis in order to determine the appropriate
allowance as of December 31, 1998.

Management strives to carefully monitor credit quality and the adequacy of the
allowance for loan losses, and to identify loans that may become nonperforming.
At June 30, 1999, total nonperforming loans were $4.1 million, or 0.52% of total
loans, compared to $1.3 million, or 0.17% of total loans, at December 31, 1998.
At any time, however, there are loans included in the portfolio that will result
in losses to Southwest, but currently have not been identified as nonperforming
or potential problem loans.  Because the loan portfolio contains a significant
number of commercial and commercial real estate loans with relatively large
balances, the unexpected deterioration of one or a few of such loans may cause a
significant increase in nonperforming assets, and may lead to a material
increase in charge-offs and the provision for loan losses.

                                       10


NOTE 5:   LOANS RECEIVABLE

Southwest extends commercial and consumer credit primarily to customers in the
State of Oklahoma, which subjects the loan portfolio to the general economic
conditions within the state.  At June 30, 1999 and December 31, 1998,
substantially all of Southwest's loans are collateralized with real estate,
inventory, accounts receivable and/or other assets, or are guaranteed by
agencies of the United States Government.

At June 30, 1999, loans to individuals and businesses in the healthcare industry
totaled approximately $81.8 million, or 10% of total loans.  Southwest does not
have any other concentrations of loans to individuals or businesses involved in
a single industry totaling 5% of total loans.

The principal balance of loans for which accrual of interest has been
discontinued totaled approximately $3.9 million at June 30, 1999.  During the
first six months of 1999, $64,000 in interest income was received on nonaccruing
loans.  If interest on those loans had been accrued, total interest income of
$227,000 would have been recorded.

Those performing loans considered potential nonperforming loans, loans which are
not included in the past due, nonaccrual or restructured categories, but for
which known information about possible credit problems causes management to be
uncertain as to the ability of the borrowers to comply with the present loan
repayment terms, amounted to approximately $31.6 million at June 30, 1999.
Loans may be monitored by management and reported as potential nonperforming
loans for an extended period of time during which management continues to be
uncertain as to the ability of certain borrowers to comply with the present loan
repayment terms.  These loans are subject to continuing management attention and
are considered by management in determining the level of the allowance for loan
losses.


NOTE 6:   LONG-TERM DEBT

The guaranteed preferred beneficial interests in Southwest's subordinated
debentures represent interests in 9.30% subordinated debentures ("Subordinated
Debentures"), due July 31, 2027, issued by Southwest to its subsidiary, SBI
Capital Trust, in connection with SBI Capital's Cumulative Trust Preferred
Securities (the "Preferred Securities").  The Subordinated Debentures and
related payments are SBI Capital's only assets.

The Preferred Securities meet the regulatory criteria for Tier I capital,
subject to Federal Reserve guidelines that limit the amount of the Preferred
Securities and cumulative perpetual preferred stock to an aggregate of 25% of
Tier I capital.


NOTE 7:   EARNINGS PER COMMON SHARE

Basic earnings per common share is computed based upon net income, after
deducting the dividend requirements of preferred stock, divided by the weighted
average number of common shares outstanding during each period.  Diluted
earnings per common share is computed based upon net income, after deducting the
dividend requirements of preferred stock, divided by the weighted average number
of common shares outstanding during each period adjusted for the effect of
dilutive potential common shares calculated using the treasury stock method.  At
June 30, 1999, there were 180,000 antidilutive options to purchase common
shares.  At June 30, 1998, there were no antidilutive options to purchase common
shares.

                                       11


The following is a reconciliation of net income available to common shareholders
and the common shares used in the calculations of basic and diluted earnings per

NOTE 8:   SHAREHOLDERS' EQUITY

Issuance of Common Stock

On March 19, 1999, Southwest completed its public offering of 1,061,231 shares
of its common stock.  The offering included 811,231 shares sold by the Estate of
Paul C. Wise and Dr. James B. Wise and 250,000 newly issued shares sold by
Southwest.  Southwest received proceeds of $5.5 million, after offering expenses
and underwriting discount.  The net proceeds were invested in Stillwater
National, where the funds will be available for general corporate purposes and
for use in lending and investment activities.  Southwest recorded $303,000 in
offering expenses paid on behalf of the selling shareholders.

Share Repurchase Program

Southwest announced in April 1999 that its Board of Directors (the "Board)
authorized the repurchase of up to 5%, or 204,000 shares, of its outstanding
common stock, par value $1.00 per share, in connection with shares expected to
be issued under Southwest's dividend reinvestment, stock option, and employee
benefit plans and for other corporate purposes. The share repurchases are
expected to be made primarily on the open market from time to time until April
30, 2001, or earlier termination of the repurchase program by the Board.
Repurchases under the program will be made at the discretion of management based
upon market, business, legal, accounting and other factors.  At June 30, 1999,
15,000 shares had been repurchased at a total cost of $337,000.

Shareholder Rights Plan

On April 22, 1999, Southwest adopted a Rights Plan designed to protect its
shareholders against acquisitions that the Board believes are unfair or
otherwise not in the best interests of Southwest and its shareholders.  Under
the Rights Plan, each holder of record of Southwest's common stock, as of the
close of business on April 22, 1999, received one right per common share.  The
rights generally become exercisable if an acquiring party accumulates, or
announces an offer to acquire, 10% or more of Southwest's voting stock.  The
rights will expire on April 22, 2009.  Each right will entitle the holder (other
than the acquiring party) to buy, at the right's then current exercise price,
Southwest's common stock or equivalent securities having a value of twice the
right's exercise price.  The exercise price of each right was initially set at
$110.00.  In addition, upon the occurrence of certain events, holders of the
rights would be entitled to purchase, at the then current exercise price, common
stock or equivalent securities of an acquiring entity worth twice the exercise
price. Under the Rights Plan, Southwest also may exchange each right, other than
rights owned by an acquiring party, for a share of its common stock or
equivalent securities.

                     Management's Discussion and Analysis
               of Financial Condition and Results of Operations


Forward Looking Statements.  This Management's Discussion and Analysis includes
forward looking statements, such as:  statements of Southwest's goals,
intentions, and expectations; estimates of risks and of future costs and
benefits; and statements of Southwest's ability to achieve financial and other
goals.  These forward looking statements are subject to significant
uncertainties because they are based upon:  future interest rates and other
economic conditions; statements by suppliers of data processing equipment and
services, government agencies, and other third parties as to year 2000
compliance and costs; future laws and regulations; and a variety of other
matters.  Because of these uncertainties, the actual future results may be
materially different from the results indicated by these forward looking
statements.  In addition, Southwest's past results do not necessarily indicate
its future results.

You should read this management's discussion and analysis of Southwest's
consolidated financial condition and results of operations in conjunction with
Southwest's consolidated financial statements and the accompanying notes.

GENERAL

Southwest Bancorp, Inc. ("Southwest") is a registered bank holding company
headquartered in Stillwater, Oklahoma.  Southwest and its subsidiary, the
Stillwater National Bank and Trust Company ("Stillwater National"), are
independent, Oklahoma institutions, and are not controlled by out of state
organizations or individuals.

Southwest offers a broad range of commercial and consumer banking and other
financial services through full service offices in Stillwater, Oklahoma City,
Tulsa and Chickasha, Oklahoma.  Southwest devotes substantial efforts to
marketing and providing services to local businesses, their primary employees,
and to other managers and professionals living and working in Southwest's
Oklahoma market areas.  Southwest has adapted to historical state branching
limitations by developing a marketing and delivery system that does not rely on
an extensive branch network.

Southwest has established and pursued a strategy of independent operation for
the benefit of all of its shareholders, and has capitalized on its position as
an Oklahoma owned and operated banking organization to increase its banking
business.  Southwest has grown from $434 million in assets at year-end 1993, to
$1.020 billion at June 30, 1999, without acquiring other financial institutions.
Southwest considers acquisitions of other financial institutions, however, from
time to time, although it does not have any specific agreements or
understandings for any such acquisition at present.

FINANCIAL CONDITION

                                       14


Total Assets

Southwest's total assets were $1.020 billion at June 30, 1999, down slightly
from $1.028 billion at December 31, 1998.

Loans Receivable

Loans were $787.1 million at June 30, 1999, a slight decrease ($6.2 million)
from December 31, 1998.  Southwest experienced increases in the categories of
residential mortgages ($11.3 million, or 14%), commercial loans ($8.2 million,
or 3%), consumer loans ($155,000, or less than 1%) and student loans ($950,000,
or 1%).  These increases were offset by reductions in commercial mortgages
($25.0 million, or 9%),  and real estate construction loans ($1.8 million, or
2%).  The allowance for loan losses increased by $540,000, or 5%, from December
31, 1998 to June 30, 1999.   At June 30, 1999, the allowance for loan losses was
$10.9 million, or 1.39% of total loans, compared to $10.4 million, or 1.31% of
total loans, at December 31, 1998.  The reduction in total loans from year-end
1998 to June 30, 1999 is the net result of growth from new loans and payoffs of
old credits.  Management expects loans for 1999 to increase, but at levels that
are less dramatic than those achieved in recent years.

Investment Securities

Investment securities were $171.7 at June 30, 1999, a reduction of $2.9 million,
or 2%, compared to December 31, 1998.  A Managed Investment Program (MIP) is
being implemented to enhance shareholder value by maximizing Southwest's use of
capital and returns on common equity.  This will be accomplished by
significantly increasing Southwest's investment securities and funding that
increase through various wholesale funding sources.  Generally, securities
acquired will have lower capital requirements than the basic 8% Risk Based
Capital guidelines, and will be classified as available for sale.  Only
securities with very high credit quality standards will be considered as
acceptable investments under the MIP.  This program could have higher interest
rate risk and less credit risk or liquidity risk than commercial loans.  All
risk ratios will be maintained within current policy guidelines.  The new
"Wholesale Division" is expected to contribute to increases in investment
securities and related net income in the third quarter of 1999 with full
implementation expected in 2000.

Premises and Equipment

Premises and equipment increased by $1.3 million primarily due to the
construction of the new Tulsa Banking Center at 15th and Utica which opened in
January 1999.

Deposits

Southwest's deposits decreased by $20.0 million, or 2%, from $843.1 million at
December 31, 1998 to $823.1 million at June 30, 1999.  Increases occurred in NOW
accounts ($6.6 million, or 15%) and savings accounts ($343,000, or 10%).  These
increases were offset by decreases in demand deposits ($8.9 million, or 7%),
money market accounts ($2.3 million, or 2%), and time deposits ($15.8 million,
or 3%) as compared to December 31, 1998.

Shareholders' Equity

Shareholders' equity increased by $8.1 million, or 14%, due primarily to
earnings, net of common stock dividends, for the first six months of 1999 and
the net proceeds of the recent public offering of 250,000 shares of common
stock.  Shareholders' equity also benefited from a $430,000 increase due to
proceeds of common stock issued through the employee stock purchase plan, the
employee stock option plan and the dividend reinvestment plan.

                                       15


These increases were offset by a $1.1 million decrease attributable to a change
in the net unrealized gains on investment securities available for sale (net of
tax) and a $337,000 decrease attributable to the purchase of treasury stock.  On
June 30, 1999, Southwest and Stillwater National continued to exceed all
applicable regulatory capital requirements.

RESULTS OF OPERATIONS

FOR THE SIX MONTH PERIODS ENDED JUNE 30, 1999 AND 1998

Net income available to common shareholders was $4.6 million for the first six
months of 1999, up 16% over the $3.9 million recorded in the first six months of
1998.  Southwest redeemed its Series A Preferred Stock on September 1, 1998.
For the first six months of 1999, net income of $4.6 million was 4% less than
the $4.7 million recorded, before deduction of dividends on preferred stock, in
the first six months of 1998.  Average common shares outstanding were 3,960,968
and 3,792,598 for the six months ended June 30, 1999 and 1998.  Basic and
diluted earnings per common share increased to $1.15 and $1.13 per share for the
first six months of 1999 from $1.04 and $1.01 per share for the same period in
1998, respectively.

Net interest income remained substantially the same during the first six months
of 1999 as for the first six months of 1998.  A $756,000, or 24%, increase in
other income, a $675,000, or 38%, reduction in the provision for loan losses,
and a $103,000 reduction in tax expense were offset by a $1.7 million, or 13%,
increase in other expenses.  For the first six months of 1999, the return on
average total equity and average common equity was 14.75% compared to a 13.80%
return on average total equity and a 15.3% return on average common equity for
the first six months of 1998.

Net Interest Income

Net interest income remained substantially the same at $18.9 million for the
first six months of 1999 from $19.0 million for the same period in 1998 as
interest income and interest expense decreased by nearly equal amounts.  Yields
on Southwest's interest-earning assets declined by 53 basis points, and the
rates paid on Southwest's interest-bearing liabilities declined by 45 basis
points, resulting in a decrease in the interest rate spread to 3.26% for the
first six months of 1999 from 3.34% for the first six months of 1998.  The ratio
of average interest-earning assets to average interest-bearing liabilities
declined to 114.83% for the first six months of 1999 from 115.87% for the first
six months of 1998, primarily due to the increase in short-term borrowings and a
larger decrease in interest-bearing deposits as compared to the decrease in
outstanding loans.

Total interest income for the first six months of 1999 was $39.5 million, down
2% from $40.2 million during the same period in 1998.  The principal cause of
the lower interest income was a 69 basis point decline in the yield on loans,
which was partially offset by a $57.5 million, or 8%, increase in the volume of
average loans outstanding.  During the same period, Southwest's average
investment securities decreased $15.5 million, or 8%, and the related yield
decreased to 5.90% from 6.22%.

Total interest expense for the first six months of 1999 was $20.5 million, a
decrease of 4% from $21.3 million for the same period in 1998.  The decrease in
total interest expense can be attributed to a 45 basis point drop in the rates
paid on average interest-bearing liabilities, partially offset by an increase in
average interest-bearing liabilities of $44.1 million, or 5%.  Rates paid on
deposits decreased for all categories; the largest reduction was a 46 basis
point reduction in the average rate paid on time deposits.

Other Income

                                       16


Other income increased by $756,000 for the first six months of 1999 compared to
the first six months of 1998 primarily as a result of a $411,000 gain on the
sale of a former branch location in Tulsa that was closed upon the opening of
the new Tulsa building at 15th and Utica.  Other increases were $389,000 in
service charges and fees and $65,000 in gains on sales of securities.  These
increases were offset by a $42,000 reduction in gains on sales of loans.  The
gains on sales of securities in 1999 and 1998 occurred when "available for sale"
securities were called prior to their stated maturity date.

Other Expenses

Southwest's other expenses increased $1.7 million for the first six months of
1999 compared to the first six months of 1998.  This increase was primarily the
result of increases in general and administrative expense ($1.2 million),
occupancy expense ($393,000) and personnel expense ($84,000).  These increases
were offset by a slight reduction in FDIC and other insurance ($7,000).  The
increase in general and administrative expense was due primarily to a $600,000
payment early in the second quarter of 1999 to settle pending litigation,
$303,000 in offering expenses paid on behalf of the selling shareholders in
Southwest's recent public offering and a $150,000 write-down of the carrying
value of an other real estate property.    The increase in occupancy expense was
due primarily to increased data processing, depreciation and equipment costs, as
systems, facilities and equipment continue to be upgraded, and other expenses
related to opening the new Tulsa Utica building.

FOR THE THREE MONTH PERIODS ENDED JUNE 30, 1999 AND 1998

Net Income

For the second quarter of 1999, Southwest recorded net income and net income
available to common shareholders of $2.5 million.  This was $45,000 more than
the $2.4 million in net income and $442,000 more than the $2.0 million in net
income available to common shareholders (after deduction of dividends on
preferred stock) recorded for the second quarter of 1998.  Southwest redeemed
its Series A Preferred Stock on September 1, 1998.  The increase in net income
was primarily the result of a $525,000 reduction in the provision for loan
losses. Average common shares outstanding were 4,077,420 for the second quarter
of 1999 and 3,794,839 for the second quarter of 1998.  Basic and diluted
earnings per common share increased to $0.60 and $0.59 per share for the second
quarter of 1999 from $0.53 and $0.51 per share for the same period in 1998,
respectively.

Net interest income decreased $151,000, or 2%, for the second quarter of 1999
compared to the same period in 1998.  This decrease in net interest income, as
well as a $898,000, or 14%, increase in other expense, and a $31,000, or 2%,
increase in tax expense, was offset by a $525,000 decrease in the provision for
loan losses and a $600,000, or 40%, increase in other income.  For the second
quarter of 1999, the return on average total equity and average common equity
was 15.03% compared to a 13.79% return on average total equity and a 15.28%
return on average common equity for the second quarter of 1998.

Net Interest Income

Net interest income decreased to $9.5 million for the second quarter of 1999
from $9.6 million for the same period in 1998 as the $638,000, or 3%, reduction
in interest income was only partially offset by a $487,000, or 5%, reduction in
interest expense.  Yields on Southwest's interest-earning assets declined by 54
basis points, and the rates paid on Southwest's interest-bearing liabilities
declined by 45 basis points, resulting in a reduction in the interest rate
spread to 3.27% for the second quarter of 1999 from 3.36% for the second quarter
of 1998.  Net interest margin also declined from 4.09% to 3.90%.  The ratio of
average interest-earning assets to average interest-bearing

                                       17


liabilities declined to 115.04% for the second quarter of 1999 from 116.09% for
the second quarter of 1998, primarily due to the increase in short-term
borrowings.

Total interest income for the second quarter of 1999 was $19.6 million, a 3%
reduction from $20.3 million during the same period in 1998.  The principal
factor in the reduction of interest income was lower yields earned on interest-
earning assets.  Southwest's average yield on loans declined to 8.55% for the
second quarter of 1999 from 9.21% in 1998.  During the same period, average
investment securities decreased $15.5 million, or 8%, and the related yield
declined to 5.84% from 6.18%.  The reduction caused by lower yields was
partially offset by the $45.4 million, or 6%, increase in the volume of average
loans outstanding.

Total interest expense for the second quarter of 1999 was $10.1 million, a
decrease of 5% from $10.6 million for the same period in 1998.  The decrease in
total interest expense can be attributed to a decrease in the rates paid on
average interest-bearing liabilities, which declined to 4.79% from 5.24%.
During the same period, average interest-bearing liabilities increased $35.1
million, or 4%.  Rates paid on deposits decreased for all categories; the
largest reduction was a 57 basis point reduction in the average rate paid on NOW
accounts.

Other Income

Other income increased by $600,000 for the second quarter of 1999 compared to
the same period of 1998 primarily as a result of a $411,000 gain on the sale of
a former branch location in Tulsa that was closed upon the opening of the new
Tulsa building at 15th and Utica.  This gain caused other noninterest income to
increase by $463,000.  Service charges and fees also increased $215,000.  These
increases were offset by a $79,000 reduction in gains on sales of loans.  The
gains on sales of securities in 1999 and 1998 occurred when "available for sale"
securities were called prior to their stated maturity date.

Other Expenses

Southwest's other expenses increased $898,000 for the second quarter of 1999
compared to the same period in 1998.  This increase was primarily the result of
a increases in general and administrative expense ($727,000), occupancy expense
($107,000) and personnel expense ($67,000).  These increases were offset by a
slight reduction in FDIC and other insurance ($3,000).  The increase in general
and administrative expense was due primarily to the $600,000 payment to settle
pending litigation.  The increase in occupancy expense was due primarily to
increased data processing, depreciation and equipment costs, as systems,
facilities and equipment continue to be upgraded.

Provision for Loan Losses

Southwest makes provisions for loan losses in amounts deemed necessary to
maintain the allowance for loan losses at an appropriate level.  The adequacy of
the allowance for loan losses is determined by management.  See Note 4,
Allowance for Loan Losses, in the Notes to Unaudited Consolidated Financial
Statements for additional information.

Taxes on Income

Southwest's income tax expense for the first six months of 1999 and 1998 was
$2.6 million and $2.7 million, respectively.  Southwest's income tax expense for
the second quarters of 1999 and 1998 was $1.4 and $1.3 million,

                                       18


respectively.  Southwest's effective tax rates have been lower than the 34%
Federal and 6% State statutory rates primarily because of tax-exempt income on
municipal obligations and loans.

LIQUIDITY

Liquidity is measured by a financial institution's ability to raise funds
through deposits, borrowed funds, capital, or the sale of highly marketable
assets such as residential mortgage loans and investment securities.
Southwest's portfolio of government-guaranteed student loans and SBA loans are
also readily salable.  Additional sources of liquidity, including cash flow from
the repayment of loans, are also considered in determining whether liquidity is
satisfactory.  Liquidity is also achieved through growth of core deposits and
liquid assets, and accessibility to the capital and money markets.  These funds
are used to meet deposit withdrawals, maintain reserve requirements, fund loans,
and operate the organization.  Core deposits, defined as demand deposits,
interest-bearing transaction accounts, savings deposits and certificates of
deposit less than $100,000 were 77% and 81% of total deposits at June 30, 1999
and 1998, respectively.

Southwest uses various forms of short-term borrowings for cash management and
liquidity purposes on a limited basis.  These forms of borrowings include
federal funds purchases, securities sold under agreements to repurchase, and
borrowings from the Federal Reserve Bank, the Student Loan Marketing Association
("SLMA") and the Federal Home Loan Bank of Topeka ("FHLB"). Stillwater National
carries interest-bearing demand notes issued by the U.S. Treasury in connection
with the Treasury Tax and Loan note program. Stillwater National has approved
federal funds purchase lines with three other banks, a $35.0 million line of
credit from the SLMA and a $55.4 million line of credit from the FHLB.
Borrowings under the SLMA line would be secured by student loans.  Borrowings
under the FHLB line would be secured by all unpledged securities and other
loans.  During the first six months of 1999, the only categories of short-term
borrowings whose averages exceeded 30% of ending shareholders' equity were
repurchase agreements and funds borrowed from the FHLB.

                                       19


During the first six months of 1999, cash and cash equivalents decreased by $1.1
million.  This decline was the result of cash used in financing activities of
$11.6 million (primarily from decrease in total deposits) which was not entirely
offset by cash generated from investing activities of $8.2 million and $2.3
million in cash provided from operating activities.

Cash and cash equivalents, during the first six months of 1998, decreased by
$14.0 million.  The decrease was the result of cash used in investing activities
of $41.4 million which was not entirely offset by cash generated from financing
activities (primarily increased short-term borrowings) of $26.6 million and
$743,000 in cash provided from operating activities.

CAPITAL RESOURCES

On March 19, 1999, Southwest completed its public offering of 1,061,231 shares
of common stock.  In April 1999, Southwest authorized the repurchase of up to
5%, or 204,000 shares, of outstanding common stock.  See Note 8 to the Unaudited
Consolidated Financial Statements.

In the first six months of 1999, total shareholders' equity increased $8.1
million, or 14%, as a result of the common stock offering, other share
issuances, and earnings, offset in part by dividends, a decrease in net
unrealized gains (losses) on investment securities and the purchase of treasury
stock.  Earnings, net of common stock dividends, contributed $3.8 million to
shareholders' equity during this six month period.  The sale of common stock
through the dividend reinvestment plan, the employee stock purchase plan and the
employee stock option plan contributed an additional $430,000 to shareholders'
equity in the first six months of 1999. Net unrealized gains (losses) on
investment securities available for sale (net of tax) decreased to $(606,000) at
June 30, 1999 compared to $513,000 at December 31, 1998.

Bank holding companies are required to maintain capital ratios in accordance
with guidelines adopted by the Federal Reserve Board ("FRB").  The guidelines
are commonly known as Risk-Based Capital Guidelines.  On June 30, 1999,
Southwest exceeded all applicable capital requirements, having a total risk-
based capital ratio of 12.15%, a Tier I risk-based capital ratio of 10.56%, and
a leverage ratio of 8.65%.  As of June 30, 1999, Stillwater National also met
the criteria for classification as a "well-capitalized" institution under the
prompt corrective action rules promulgated under the Federal Deposit Insurance
Act.  Designation as a well-capitalized institution under these regulations does
not constitute a recommendation or endorsement of Southwest or Stillwater
National by Federal bank regulators.

Southwest declared a dividend of $.10 per common share payable on July 1, 1999
to shareholders of record as of June 17, 1999.

EFFECTS OF INFLATION

The consolidated financial statements and related consolidated financial data
presented herein have been prepared in accordance with generally accepted
accounting principles and practices within the banking industry which require
the measurement of financial position and operating results in terms of
historical dollars without considering the

                                       20


changes in the relative purchasing power of money over time due to inflation.
Unlike most industrial companies, virtually all the assets and liabilities of a
financial institution are monetary in nature. As a result, interest rates have a
more significant impact on a financial institution's performance than the
effects of general levels of inflation.

YEAR 2000 ISSUES

Many computer programs now in use have not been designed to properly recognize
years after 1999.  If not corrected, these programs could fail or create
erroneous results.  This Year 2000 ("Y2K") issue affects the entire banking
industry because of its reliance on computers and other equipment that use
computer chips.  This problem is not limited to computer systems.  Y2K issues
may affect every system that has an embedded microchip, such as automated teller
machines, elevators, vaults, heating, air conditioning, and security systems.
Y2K issues may also affect the operation of third parties with whom Southwest
does business such as vendors, suppliers, utility companies, and customers.

The Y2K issue poses certain risks to Southwest and its operations.  Some of
these risks are present because Southwest purchases technology and information
system applications from other parties who also face Y2K challenges.  Other
risks are specific to the banking industry.

Commercial banks may experience a deposit base reduction if customers withdraw
significant amounts of cash in anticipation of Y2K.  Such a deposit contraction
could cause an increase in interest rates, require Southwest to locate
alternative sources of funding or sell investment securities or other liquid
assets to meet liquidity needs, and may reduce future earnings.  To reduce
customer concerns regarding Y2K noncompliance, a customer awareness plan has
been implemented which is directed towards making deposit customers
knowledgeable about Southwest's Y2K compliance efforts.

Southwest lends significant amounts to businesses and individuals in its
marketing areas.  If these borrowers are adversely affected by Y2K problems,
they may not be able to repay their loans in a timely manner.  This increased
credit risk could adversely affect Southwest's financial performance.  In an
effort to identify any potential loan loss risk because of borrower Y2K
noncompliance, all loan customers with loans or commitments exceeding $500,000
were asked to complete a Y2K questionnaire.  Where the customer did not reply,
the loan officer personally contacted the customer.  Southwest purchased
software to assist it in interpreting the responses, and has analyzed the
results and any risks identified.  Southwest has also modified its loan
underwriting controls to ensure that potential borrowers are carefully evaluated
for Y2K compliance before any new loan is approved.

Southwest's operations, like those of many other companies, can be adversely
affected by Y2K triggered failures which may be experienced by third parties
upon whom Southwest relies for processing transactions.  Southwest has
identified all critical third-party service providers and vendors and is
monitoring their Y2K compliance programs.  Southwest's primary supplier of data
processing services has adopted a Y2K compliance plan, which includes a
timetable for making changes necessary to be able to provide services in the
year 2000.  That supplier has provided written assurances to Southwest regarding
its progress toward Y2K compliance and has been examined for Y2K readiness by
federal bank examiners.

Southwest's operations may also be adversely affected by Y2K related failures of
third party providers of electricity, telecommunications services and other
utility services.  Although Southwest's contingency plan includes backup power
generation, failures in these areas could impact Southwest's ability to conduct
business.  The Y2K compliance of these providers is largely beyond the control
of Southwest.

                                       21


Southwest has created a task force to establish a Y2K plan to prevent or
mitigate the adverse effects of the Y2K issue on Southwest and its customers.
Goals of the Y2K plan include identifying Y2K risks related to information
systems and equipment used by Southwest, informing customers of Y2K issues and
risks they may encounter personally, implementing changes in systems and
equipment necessary to achieve Y2K compliance, verifying that these changes are
effective, and establishing a contingency plan for operations in 2000 if
problems do arise.  Federal bank examiners are examining all banking
organizations for Y2K compliance.  The Comptroller of the Currency has examined
Southwest's Y2K compliance plan and its implementation progress.  In addition,
the Board is carefully monitoring progress under the plan on a monthly basis.

Southwest's plan to address the Y2K issue involves several phases, described
below:

     .    Awareness - In this phase, Southwest's Y2K plan and project team were
          established, the overall Y2K approach was identified, compliance
          standards were defined, and responsibility for corrective action was
          assigned. This phase has been completed.

     .    Assessment - During this phase, Southwest gathered and analyzed
          information to determine the size and the impact of the Y2K problem
          and then made decisions to modify, re-engineer, or replace existing
          systems and programs. This phase has been completed.

     .    Renovation - This phase involves obtaining and implementing upgraded
          software applications provided by Southwest's vendors, modifying
          system codes, reengineering Y2K vulnerable systems and programs,
          developing bridges for systems which cannot be reengineered, and
          changing files and databases as necessary. This phase has been
          completed.

     .    Validation - During the validation phase, Southwest is testing systems
          and software for Y2K compliance in an effort to identify and correct
          any errors that may be identified in the renovation phase. This phase
          has been completed.

     .    Implementation - In this phase, all new and revised systems will be
          implemented, data exchange issues will be resolved, and backup and
          recovery plans will be developed. This phase is in process and will be
          fully executed by December 31, 1999.

Based on information developed to date, management believes that the cost of
remediation will not be material to Southwest's business, operations, liquidity,
capital resources, or financial condition.  Southwest estimates that total cash
outlays in connection with Y2K compliance will be less than $500,000, excluding
costs of employees involved in Y2K compliance activities.  Southwest is funding
Y2K expenditures through continuing operations.

Designated personnel will report to work on January 1 and 2, 2000, (Saturday and
Sunday) to assess the proper functioning of critical and non-critical systems.
In the event that some or all systems experience failure, Southwest has
developed a detailed contingency plan.  This plan calls for manual processing of
bank transactions at a designated location supported by a backup power system.
Delays in processing transactions would result in the event that Southwest is
forced to process transactions manually.  These delays could disrupt normal
business activities of Southwest and its customers.

The discussion above regarding issues associated with Y2K includes certain
forward looking statements.  Southwest's ability to predict results or effects
of issues related to the Y2K issue is inherently uncertain and is subject to
factors that may cause actual results to differ materially from those projected.
Factors that could affect the actual results include the following:

     .    The possibility that protection procedures, contingency plans, and
          remediation efforts will not operate as intended;

     .    Southwest's failure to timely or completely identify all software or
          hardware applications requiring remediation;

                                       22


     .    Unexpected costs;

     .    The uncertainty associated with the impact of Y2K issues on the
          banking industry and Southwest's customers, vendors, and others with
          whom it conducts business; and

     .    The general economy.
