                             SOUTHWEST BANCORP, INC.

              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, shareholders' equity, cash flows and
comprehensive income in conformity with accounting principles generally accepted
in the United States of America. However, the unaudited consolidated financial
statements include all adjustments which, in the opinion of management, are
necessary for a fair presentation. Those adjustments consist of normal,
recurring adjustments. The results of operations for the three and nine months
ended September 30, 2004 and the cash flows for the nine months ended September
30, 2004 should not be considered indicative of the results to be expected for
the full year. These unaudited 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, 2003.


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"), SNB Bank of Wichita ("SNB Wichita"), Healthcare Strategic Support,
Inc. ("HSSI"), and Business Consulting Group, Inc. ("BCG"). All significant
intercompany transactions and balances have been eliminated in consolidation.


NOTE 3: INVESTMENT SECURITIES

At September 30, 2004, Southwest had gross unrealized losses in its available
for sale securities portfolio totaling $1.1 million. Fifteen securities with a
par value of $22.8 million and an unrealized loss of $387,000 had been in an
unrealized loss position for more than twelve months. These gross unrealized
losses occurred due to increases in interest rates and spreads rather than
credit impairment. Southwest has the intent and ability to hold these securities
until the unrealized loss is recovered.


NOTE 4: LOANS RECEIVABLE

Southwest extends commercial and consumer credit primarily to customers in the
states of Oklahoma, Kansas and Texas. Its commercial lending operations are
concentrated in the Stillwater, Tulsa, and Oklahoma City areas of Oklahoma; in
Wichita, Kansas; and in the Dallas and Austin, Texas metropolitan areas. As a
result, the collectibility of Southwest's loan portfolio can be affected by
changes in the general economic conditions in these three states and in those
metropolitan areas. At September 30, 2004 and December 31, 2003, substantially
all of Southwest's loans were collateralized with real estate, inventory,
accounts receivable, and/or other assets, or were guaranteed by agencies of the
United States Government.

At September 30, 2004, loans to individuals and businesses in the healthcare
industry totaled approximately $379.0 million, or 24%, of total loans and
student loans totaled approximately $341.3 million, or 21%, of total loans.
Southwest does not have any other concentrations of loans to individuals or
businesses involved in a single industry totaling 5% or more of total loans.


Nonperforming assets and other risk elements of the loan portfolio are shown
below as of the indicated dates. Total nonaccrual loans increased $13.9 million,
or 96%, from December 31, 2003, and total nonperforming loans increased $14.8
million, or 93%. Total nonperforming assets of $33.2 million (which includes
other real estate owned) increased $15.6 million, or 89%.

Nonperforming loans to loans receivable                                                      1.91%                        1.22%

Nonperforming assets to loans receivable and
     other real estate owned                                                                 2.06%                        1.34%


(1) The government-guaranteed portion of loans included in these totals was $1.4
million (2004) and $2.5 million (2003).

The principal balance of loans for which accrual of interest has been
discontinued totaled approximately $28.5 million at September 30, 2004. All of
the nonaccruing assets are subject to regular tests for impairment as part of
Southwest's allowance for loan losses methodology (see below). Five credit
relationships accounted for approximately $21.7 million, or 71% of total
nonperforming loans at September 30, 2004. All of these credits were identified
as problem or potential problem credits in previous quarters. Management
continues to actively manage these relationships, and anticipates they will be
significantly reduced within the next six months through payoffs from proceeds
from the sale of collateral now being actively marketed, proceeds of planned
debtor capital increases, payments by guarantors, or by restructuring into
earning assets.

During the first nine months of 2004, $51,000 in interest income was received on
nonaccruing loans. If interest on those loans had been accrued for the nine
months ended September 30, 2004, additional total interest income of $872,000
would have been recorded.

Performing loans considered potential nonperforming loans (loans that are not
included in the past due, nonaccrual or restructured categories but for which
known information about possible credit problems cause management to have doubts
as to the ability of the borrowers to comply with the present loan repayment
terms and which may become nonperforming in the future) amounted to
approximately $33.3 million at September 30, 2004, compared to $37.8 million at
December 31, 2003, a decrease of 12%. 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.

Southwest makes provisions for loan losses in amounts necessary to maintain the
allowance for loan losses at the level Southwest determines is appropriate based
on a systematic methodology. The allowance is based on careful, continuous
review and evaluation of the loan portfolio and ongoing, quarterly assessments
of the probable losses inherent in the loan and lease portfolio and unused
commitments to provide financing. Southwest's systematic methodology for
assessing the appropriateness of the allowance includes determination of a
formula allowance, specific allowances and a general allowance. The formula
allowance is calculated by applying loss factors to corresponding categories of
outstanding loans and leases. Loss factors generally are based on Southwest's
historical loss experience in the various portfolio categories over the prior
eighteen months or twelve months, but may be adjusted for categories where
eighteen and twelve month loss experience is historically unusual and not
considered indicative of the losses inherent in specific portfolio categories.
The use of these loss factors is intended to reduce the differences between
estimated losses inherent in the portfolio and observed losses. Formula
allowances also are established for loans that do not have specific allowances
according to the application of credit risk factors. These factors are set by
management to reflect its assessment of the relative level of risk inherent in
each grade. Specific allowances are established in cases where management has
identified significant conditions or circumstances related to individual loans
that management believes indicate the probability that losses may be incurred in
an amount different from the amounts determined by application of the formula
allowance. Specific allowances include amounts related to loans that are
identified for evaluation of impairment, which is based on discounted cash flows
using each loan's initial effective interest rate or on the fair value of the
collateral for certain collateral dependent loans. All of Southwest's nonaccrual
loans are considered to be impaired loans. The general allowance is based upon
management's evaluation of various factors that are not directly measured in the
determination of the formula and specific allowances. These factors may include
general economic and business conditions affecting lending areas, credit quality
trends (including trends in delinquencies and nonperforming loans expected to
result from existing conditions), loan volumes and concentrations, specific
industry conditions within portfolio categories, recent loss experience in
particular loan categories, duration of the current business cycle, bank
regulatory examination results, findings of internal credit examiners, and
management's judgment with respect to various other conditions including credit
administration and management and the quality of risk identification systems.
Management reviews these conditions quarterly. There were no changes in
estimation methods or assumptions that affected the methodology for assessing
the appropriateness of the allowance during the third quarter of 2004. Southwest
determined the level of the allowance for loan losses at September 30, 2004, was
appropriate, based on that methodology.

Management strives to carefully monitor credit quality and to identify loans
that may become nonperforming. At any time, however, there are loans included in
the portfolio that will result in losses to Southwest, but that 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 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 in
future periods.


NOTE 6:  STOCK OPTION PLAN

The Southwest Bancorp, Inc. 1994 Stock Option Plan and 1999 Stock Option Plan
(the "Stock Plans") provide selected key employees with the opportunity to
acquire common stock. The exercise price of all options granted under the Stock
Plans is the fair market value on the grant date. Depending upon terms of the
stock option agreements, stock options generally become exercisable on an annual
basis and expire from five to ten years after the date of grant. Southwest
applies Accounting Principles Board Opinion No. 25 and related interpretations
in accounting for the Stock Plans; accordingly, no compensation expense related
to the grants of stock options has been recorded in the accompanying
consolidated statements of operations. Had compensation cost for the Stock Plans
been determined based upon the fair value of the options at their grant date as
prescribed in Statement of Financial Accounting Standard ("SFAS") No. 123,
Accounting for Stock-Based Compensation, as amended by SFAS No. 148, Accounting
for Stock-Based Compensation - Transition and Disclosure, Southwest's proforma

NOTE 7: EARNINGS PER SHARE

Basic earnings per share is computed based upon net income divided by the
weighted average number of shares outstanding during each period. Diluted
earnings per share is computed based upon net income divided by the weighted
average number of shares outstanding during each period adjusted for the effect
of dilutive potential shares calculated using the treasury stock method. At
September 30, 2004 and 2003, there were no antidilutive options to purchase
common shares.

NOTE 8:  OPERATING SEGMENTS

Southwest operates four principal segments: Oklahoma Banking, Other States
Banking, loans originated for sale in the secondary market ("Secondary Market"),
and an Other Operations segment. The Oklahoma Banking segment consists of three
operating units that provide lending and deposit services to customers in the
state of Oklahoma. The Other States Banking segment consists of three operating
units that provide lending and deposit services to the customers in the states
of Texas and Kansas. The Secondary Market segment consists of two operating
units that provide student lending services to post-secondary students in
Oklahoma and several other states and residential mortgage lending services to
customers in Oklahoma, Texas, and Kansas. Southwest's fund management unit is
included in Other Operations. The primary purpose of the fund management unit is
to manage Southwest's overall liquidity needs and interest rate risk. Each
segment borrows funds from and provides funds to the funds management unit as
needed to support its operations.

Southwest identifies reportable segments by type of service provided and
geographic location. Operating results are adjusted for intercompany loan
participations and borrowings, allocated service costs, and management fees.

The accounting policies of each reportable segment are the same as those of
Southwest. Expenses for consolidated back-office operations are allocated to
operating segments based on estimated uses of those services. General overhead
expenses such as executive administration, accounting and internal audit are
allocated based on the direct expense and/or deposit and loan volumes of the
operating segment. Income tax expense for the operating segments is calculated
essentially at statutory rates. The Other Operations segment records the tax
expense or benefit necessary to reconcile the consolidated financial statements.

The following table summarizes financial results by operating segment:

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS


Forward-Looking Statements. This management's discussion and analysis of
financial condition and results of operations, the notes to Southwest's
unaudited consolidated financial statements, and other portions of this report
include forward-looking statements such as: statements of Southwest's goals,
intentions, and expectations; estimates of risks and of future costs and
benefits; expectations regarding future financial performance of Southwest and
its operating segments; assessments of loan quality, probable loan losses, and
the amount and timing of loan payoffs; liquidity, contractual obligations,
off-balance sheet risk, and market or interest rate risk; 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:
the amount and timing of future changes in interest rates, market behavior, and
other economic conditions; future laws, regulations, and accounting principles;
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 growth and performance
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 unaudited consolidated financial statements and the accompanying
notes.


GENERAL

Southwest Bancorp, Inc. ("Southwest") is a financial holding company for the
Stillwater National Bank and Trust Company ("Stillwater National"), SNB Bank of
Wichita ("SNB Wichita"), Healthcare Strategic Support, Inc., and Business
Consulting Group, Inc. ("BCG"). Southwest is an independent institution.

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, Wichita, Kansas and metropolitan Dallas, Texas;
loan production offices on the campuses of the University of Oklahoma Health
Sciences Center in Oklahoma City, Oklahoma State University-Tulsa, and in
metropolitan Dallas and Austin, Texas; a marketing presence in the Student Union
at Oklahoma State University-Stillwater; and on the Internet, through SNB
DirectBanker(R). 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 market areas.

Southwest's strategic focus includes expansion in carefully selected geographic
markets based upon a tested business model developed in connection with our
expansion into Oklahoma City in 1982. This geographic expansion is based on
identification of markets with concentrations of customers in Southwest's
traditional areas of expertise: healthcare and health professionals, businesses
and their managers and owners, and commercial and commercial real estate
lending, and makes uses of traditional and specialized financial services.
Specialized 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, and management consulting
services through Southwest's management consulting subsidiaries: Healthcare
Strategic Support, Inc., serving physicians, hospitals, and healthcare groups,
and Business Consulting Group, Inc., serving small and large commercial
enterprises.

During 2002, Southwest established offices in Wichita, Kansas and Dallas, Texas.
At September 30, 2004, we had five offices in Kansas and Texas. During the first
nine months of 2004, these offices produced $2.0 million in net income (15% of
the consolidated total), up over 100% from the first nine months of 2003, and
$113.2 million in new banking assets. Southwest has received regulatory approval
to expand further in Texas by opening a second branch office in the Dallas
metropolitan area. The office is located in Preston Center at 5950 Berkshire
Lane, Dallas, Texas where it is currently operating as a loan production office.
The Preston Center location will begin operating as a full service branch during
the last half of December 2004. Southwest has also applied to open an additional
branch office in Austin, Texas, where it is currently operating a loan
production office.


                                       14


Our Oklahoma Banking segment accounted for $7.0 million, or 51%, of year-to-date
net income, and $39.5 million in new banking assets during the first nine months
of 2004.

Southwest has a long history of student and residential mortgage lending. These
operations comprise our Secondary Market business segment. During the first nine
months of 2004, this segment produced $6.9 million in net income, up 80% from
the same period in 2003, and $135.6 million in additional banking assets. This
growth was the result of expanded student lending, which more than offset the
effects of the residential mortgage slowdown. Loan volumes in the Secondary
Market segment may vary significantly from period to period.

For additional information on our operating segments, please see Note 8,
Operating Segments, above. The total of net income of the segments discussed
above exceeds consolidated net income for the first nine months of 2004 due to
losses allocated to the Other Operations segment, which provides funding and
liquidity services to the rest of the organization.

Southwest has established and pursued a strategy of independent operation for
the benefit of all of its shareholders. Southwest has grown from $434 million in
assets since becoming a public company at year-end 1993, to nearly $1.9 billion
at September 30, 2004, without acquiring other financial institutions. Southwest
considers acquisitions of other financial institutions and other companies from
time to time, although it does not have any specific agreements or
understandings for any such acquisition at present. Southwest also considers,
from time to time, the establishment of new lending, banking and other offices
in additional geographic markets. Southwest also extends loans to borrowers in
Oklahoma and neighboring states through participations with correspondent banks.

Management determines the appropriate level of the allowance for loan losses
using a systematic methodology. (See Note 5, "Allowance for Loan Losses," in the
Notes to Unaudited Consolidated Financial Statements.) The allowance for loan
losses increased by $4.1 million, or 26%, from December 31, 2003 to September
30, 2004, mainly as a result of growth in portfolio loans (loans other than
loans held for sale), especially from our Texas and Kansas offices, and amounts
required for nonperforming loans. At September 30, 2004, the allowance for loan
losses was $19.9 million, or 1.24% of total loans and 64.78% of nonperforming
loans, compared to $15.8 million, or 1.21% of total loans and 99.59% of
nonperforming loans, at December 31, 2003. Substantially all of the allowance is
related to portfolio loans. The allowance allocated to portfolio loans was 1.58%
of portfolio loans at September 30, 2004, compared to 1.45% at December 31,
2003. (See "Results of Operations-Provision for Loan Losses.")

DEPOSITS AND OTHER BORROWINGS

Southwest's deposits were $1.4 billion at September 30, 2004, an increase of
$220.8 million, or 18%, from $1.2 billion at December 31, 2003. Increases
occurred in all categories of deposits as shown in the following table:

Stillwater National has unsecured brokered certificate of deposit lines of
credit in connection with its retail certificate of deposit program from Merrill
Lynch & Co., Morgan Stanley & Co., Inc., Dean Witter, Citigroup Global Markets,
Inc., Wachovia Securities LLC, UBS Financial Services, Inc., RBC Capital Markets
Corp. and CountryWide Securities that total $1.2 billion. At September 30, 2004,
$374.6 million in these retail certificates of deposit were included in total
deposits, an increase of $149.0 million, or 66%, from year-end 2003. Stillwater
National has other brokered certificates of deposit totaling $31.4 million
included in total deposits at September 30, 2004.

Other borrowings increased $61.9 million, or 34%, to $245.7 million during the
first nine months of 2004.

SHAREHOLDERS' EQUITY

Shareholders' equity increased by $12.2 million, or 11%, due primarily to
earnings for the first nine months of 2004, and stock option exercises, offset
in part by common stock dividends and a decrease in accumulated other
comprehensive income (net, after tax, unrealized gains on investment securities
available for sale). At September 30, 2004, Southwest, Stillwater National and
SNB Wichita continued to exceed all applicable regulatory capital requirements.

RESULTS OF OPERATIONS

FOR THE THREE MONTH PERIODS ENDED SEPTEMBER 30, 2004 and 2003

Net income for the third quarter of 2004 of $4.9 million represented an increase
of $1.4 million, or 42%, over the $3.4 million earned in the third quarter of
2003. Diluted earnings per share were $0.39 compared to $0.28, a 39% increase.
The increase in net income was primarily the result of a $4.8 million, or 34%,
increase in net interest income (fueled by substantial loan growth and increased
interest margin), and a $129,000, or 3%, increase in other income (due mainly to
increased service charges on deposit accounts), offset in part by a $1.2
million, or 43%, increase in the provision for loan losses, a $1.3 million, or
13%, increase in other expense (mainly as a result of increased occupancy and
general and administrative expenses), and a $955,000, or 49%, increase in taxes
on income.

On an operating segment basis, the increase in net income was led by an $1.4
million increase in net income for the Secondary Market segment, due primarily
to increased student lending volume, and a $502,000 reduction in the deficit
from Other Operations, offset by declines in Oklahoma and Other States Banking.
The decreases in Oklahoma and Other States Banking were largely the result of
increased provision for loan losses and noninterest expense. The Secondary
Market segment contributed the largest portion ($2.8 million) of Southwest's net
income in the third quarter 2004. The contribution from the Secondary Market
segment may vary significantly from period to period as a result of changes in
loan volume, interest rates and market behavior; the number of schools
participating in Southwest's student lending programs, the sizes of their
enrollment, and the graduation status of student borrowers; and other factors.

Net interest income is the difference between the interest income Southwest
earns on its loans, investments and other interest-earning assets, and the
interest paid on interest-bearing liabilities, such as deposits and borrowings.
Because different types of assets and liabilities owned by Southwest may react
differently, and at different times, to changes in market interest rates, net
interest income is affected by changes in market interest rates. When
interest-bearing liabilities mature or reprice more quickly than
interest-earning assets in a period, an increase of market rates of interest
could reduce net interest income. Similarly, when interest-earning assets mature
or reprice more quickly than interest-bearing liabilities, falling interest
rates could reduce net interest income.

Yields on Southwest's interest-earning assets increased 39 basis points, and the
rates paid on Southwest's interest-bearing liabilities declined by 5 basis
points, resulting in an increase in the interest rate spread to 3.91% for the
third quarter of 2004 from 3.47% for the third quarter of 2003. During the same
periods, annualized net interest margin increased from 3.78% to 4.19%. The ratio
of average interest-earning assets to average interest-bearing liabilities
decreased to 115.65% for the third quarter of 2004 from 116.70% for the third
quarter of 2003.

The principal factor in the increase of interest income was the $306.6 million,
or 21%, increase in average interest-earning assets. Interest income also
benefited from the 39 basis point increase in the yield earned on
interest-earning assets. Southwest's average loans increased $284.5 million, or
22%, and the related yield increased to 6.35% for the third quarter of 2004 from
5.89% in 2003. During the same period, average investment securities increased
$21.6 million, or 11%, and the related yield was reduced to 3.60% from 3.91%.

The increase in total interest expense can be attributed to the $276.7 million,
or 22%, increase in average interest-bearing liabilities, which was partially
offset by the 5 basis point reduction in the rates paid on interest-bearing
liabilities. The increase in interest expense on subordinated debentures is due
to two new issuances of subordinated debentures that occurred in the third and
fourth quarters of 2003. Rates paid on deposits decreased for all categories
other than money market accounts, which increased 5 basis points.

Other income increased $129,000, or 3%, due primarily to the $247,000 increase
in other service charges. This increase occurred due to the repricing of service
charges on deposit accounts to be more consistent with other financial
institutions in our markets. Another contributing factor was the $138,000, or
73%, increase in other noninterest income. The increase in other noninterest
income occurred primarily due to a $128,000 increase in consulting fees
generated by Southwest's subsidiaries, Healthcare Strategic Services, Inc. and
Business Consulting Group, Inc.

Gain on sales of loans receivable declined due primarily to a $333,000, or 50%,
reduction in gain on sales of mortgage loans, which occurred due to the lower
refinancing demand created by higher mortgage interest rates during the third
quarter of 2004 as compared to those prevalent during the third quarter of 2003.
During the same period, gain on sales of student loans increased $199,000 and
gain on sales of other loans increased $49,000. The loss on sales of investment
securities, which were all classified as available for sale, occurred when four
securities that had passed their call dates were sold. Southwest has the intent
and ability to hold all remaining investment securities with an unrealized loss
until the fair value exceeds amortized cost.

Southwest's multi-state ATM network operated 286 ATM machines in 25 states at
September 30, 2004 compared to 334 ATM machines in 22 states at September 30,
2003. The number of machines operated has stayed fairly constant during 2004
following a decrease during the fourth quarter of 2003 when a contract with a
convenience store chain was not renewed. This fourth quarter 2003 reduction in
ATM machines being operated is the primary reason for the decrease in ATM
service charges from $879,000 in the third quarter 2003 to $794,000 in the third
quarter 2004.

Salaries and employee benefits increased $363,000 primarily as a result of an
increase in the number of employees as well as normal compensation increases.
The number of full-time equivalent employees increased from 331 to 360 during
the third quarter of 2004 and from 326 to 340 during the third quarter of 2003.


                                       19


The primary factor in the increase of occupancy expense was a $376,000 increase
in data processing charges for student loans due to a larger volume of loans
being processed.

The increase in general and administrative expenses reflected increased fees
paid in connection with government-guaranteed loans, which increased $122,000, a
$95,000 increase in legal fees, primarily related to the collection of past due
loans, and expenses related to the development of business relationships in our
new and current market areas, which increased by $54,000.


FOR THE NINE MONTH PERIODS ENDED SEPTEMBER 30, 2004 and 2003

Net income for the first nine months of 2004 of $13.7 million represented an
increase of $2.7 million, or 25%, over the $11.0 million earned in the first
nine months of 2003. Diluted earnings per share were $1.09 compared to $0.90, a
21% increase. The increase in net income was primarily the result of a $10.9
million, or 27%, increase in net interest income (fueled by substantial loan
growth and increased interest margin), offset in part by a $1.7 million, or 26%,
increase in the provision for loan losses, a $549,000, or 5%, decline in other
income (due mainly to lower gains on loans sold), and a $4.3 million, or 15%,
increase in other expense (mainly as a result of increased salaries and benefits
from increased staff and executive retirement expense, and increased occupancy
and general and administrative expenses).

On an operating segment basis, the increase in net income was led by a $3.1
million increase in net income from the Secondary Market segment, due primarily
to increased student lending volume, and a $1.0 million increase in the
contribution from Other States Banking, offset by a decline in Oklahoma Banking
and an increased deficit in Other Operations. The decrease in Oklahoma Banking
was largely the result of increased noninterest expense, which included an
executive retirement charge. Oklahoma Banking continues to provide the largest
portion ($7.0 million) of Southwest's net income. However, in the first nine
months, the contribution of Other States Banking was approximately 15%, while
the Secondary Market segment contributed $6.9 million, or 51%. The contribution
from the Secondary Market segment may vary significantly from period to period
as a result of changes in loan volume, interest rates and market behavior; the
number of schools participating in Southwest's student lending programs, the
sizes of their enrollment, and the graduation status of student borrowers; and
other factors.

Net interest income is the difference between the interest income Southwest
earns on its loans, investments and other interest-earning assets, and the
interest paid on interest-bearing liabilities, such as deposits and borrowings.
Because different types of assets and liabilities owned by Southwest may react
differently, and at different times, to changes in market interest rates, net
interest income is affected by changes in market interest rates. When
interest-bearing liabilities mature or reprice more quickly than
interest-earning assets in a period, an increase of market rates of interest
could reduce net interest income. Similarly, when interest-earning assets mature
or reprice more quickly than interest-bearing liabilities, falling interest
rates could reduce net interest income.

Yields on Southwest's interest-earning assets increased 9 basis points, and the
rates paid on Southwest's interest-bearing liabilities declined 23 basis points,
resulting in an increase in the interest rate spread to 3.79% for the first nine
months of 2004 from 3.47% for the first nine months of 2003. During the same
periods, annualized net interest margin increased from 3.78% to 4.07%. The ratio
of average interest-earning assets to average interest-bearing liabilities
decreased to 115.82% for the first nine months of 2004 from 116.05% for the
first nine months of 2003.

The principal factor in the increase of interest income was the $251.7 million,
or 17%, increase in average interest-earning assets. Interest income also
benefited from the 9 basis point increase in the yield earned on
interest-earning assets. Southwest's average loans increased $225.9 million, or
18%, and the related yield increased to 6.19% for the first nine months of 2004
from 6.01% in 2003. During the same period, average investment securities
increased $25.8 million, or 14%, and the related yield was reduced to 3.69% from
4.26%.

The decline in total interest expense can be attributed to the 23 basis point
reduction in the rates paid on interest-bearing liabilities, which was partially
offset by the $219.9 million, or 18%, increase in average interest-bearing
liabilities. The increase in interest expense on subordinated debentures is due
to two new issuances of subordinated debentures that occurred in the third and
fourth quarters of 2003. Rates paid on deposits decreased for all categories.

Gain on sales of loans receivable, the major factor in the reduction of other
income, declined due primarily to an $1.2 million reduction in gain on sales of
mortgage loans, which occurred due to the lower refinancing demand created by
slightly higher mortgage interest rates during the first nine months of 2004 as
compared to those prevalent during the same period in 2003. The loss on sales of
investment securities, which were all classified as available for sale, occurred
when four securities that had passed their call dates were sold during the third
quarter. Southwest has the intent and ability to hold all remaining investment
securities with an unrealized loss until the fair value exceeds amortized cost.

These reductions in other income were partially offset by the $396,000 increase
in service charges and fees. The increase in service charges and fees occurred
due to repricing of service charges on deposit accounts to be more consistent
with other financial institutions in the markets we serve.

Southwest's multi-state ATM network operated 286 ATM machines in 25 states at
September 30, 2004 compared to 334 ATM machines in 22 states at September 30,
2003. The number of machines operated has stayed fairly constant during 2004
following a decrease during the fourth quarter of 2003 when a contract with a
convenience store chain was not renewed. This fourth quarter 2003 reduction in
ATM machines being operated is the primary reason for the decrease in ATM
service charges from $2.6 million in 2003 to $2.3 million in 2004.

Salaries and employee benefits increased $1.5 million primarily as a result of
an increase in the number of employees, a charge relating to executive
retirement in the first quarter of 2004 of approximately $492,000, as well as
normal compensation increases. The number of full-time equivalent employees
increased to 360 at the end of September 2004 from 340 at the end of September
2003.

The primary factor in the increase of occupancy expense was a $794,000 increase
in data processing charges for student loans due to a larger volume of loans
being processed.

The increase in general and administrative expenses reflected increased fees
paid in connection with government-guaranteed loans, which increased by
$275,000, expenses related to the development of business relationships in our
new and current market areas, which increased by $234,000, and a $208,000
increase in legal fees, primarily related to the collection of past due loans.
Losses on deposit accounts increased $91,000, which is primarily attributable to
three deposit account relationships.

PROVISION FOR LOAN LOSSES

Southwest makes provisions for loan losses in amounts necessary to maintain the
allowance for loan losses at the level Southwest determines is appropriate based
on a systematic methodology. (See Note 5, "Allowance for Loan Losses," in the
Notes to Unaudited Consolidated Financial Statements.)

The allowance for loan losses of $19.9 million increased $4.1 million, or 26%,
from year-end 2003. A provision for loan losses of $8.1 million was recorded in
the first nine months of 2004, an increase of $1.7 million, or 26%, from the
first nine months of 2003. (See Note 4, "Loans Receivable," in the Notes to
Unaudited Consolidated Financial Statements.)

TAXES ON INCOME

Southwest's income tax expense was $7.9 million and $6.2 million for the first
nine months of 2004 and 2003, respectively, an increase of $1.7 million, or 28%.
Southwest's effective tax rates have been lower than federal and state statutory
rates primarily because of tax-exempt income on municipal obligations and loans,
the organization in July 2001 of a real estate investment trust and tax credits
generated by certain lending and investment activities.


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 available for sale investments.
Southwest's portfolio of student loans and SBA loans are also readily salable.
Additional sources of liquidity, including cash flow from the repayment of loans
and the sale of participations in outstanding loans, are also considered in
determining whether liquidity is satisfactory. Liquidity is also achieved
through growth of 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.


                                       23


Southwest has available various forms of short-term borrowings for cash
management and liquidity purposes. These forms of borrowings include federal
funds purchased, securities sold under agreements to repurchase, and borrowings
from the Federal Reserve Bank ("FRB"), the Student Loan Marketing Association
("SLMA"), the F&M Bank of Tulsa ("F&M"), and the Federal Home Loan Bank of
Topeka ("FHLB"). Stillwater National also carries interest-bearing demand notes
issued by the U.S. Treasury in connection with the Treasury Tax and Loan note
program; the outstanding balance of those notes was $1.7 million at September
30, 2004. Stillwater National has approved federal funds purchase lines totaling
$216.5 million with two other banks and four institutional brokers; $44.1
million was outstanding on these lines at September 30, 2004. In addition,
Stillwater National has available a $35.0 million line of credit from the SLMA
and a $318.0 million line of credit from the FHLB and SNB Wichita has a $8.9
million line of credit from the FHLB. Borrowings under the SLMA line would be
secured by student loans. Borrowings under the FHLB lines are secured by
investment securities and loans. The SLMA line expires April 20, 2007; no amount
was outstanding on this line at September 30, 2004. The Stillwater National FHLB
line of credit had an outstanding balance of $165.9 million at September 30,
2004; no amount was outstanding on the SNB Wichita line of credit at the FHLB at
September 30, 2004. See also "Deposits and Other Borrowings" on page 16.

Stillwater National sells securities under agreements to repurchase with
Stillwater National retaining custody of the collateral. Collateral consists of
direct obligations of U.S. Government Agency issues, which are designated as
pledged with Stillwater National's safekeeping agent. These transactions are for
one-to-four day periods.

During the first nine months of 2004, the only categories of other borrowings
whose averages exceeded 30% of ending shareholders' equity were repurchase
agreements and funds borrowed from the FHLB.

During the first nine months of 2004, cash and cash equivalents decreased by
$3.0 million, or 9%, to $31.0 million. This decrease was the net result of cash
used in net loan origination and other investing activities of $160.1 million
and cash used in operating activities of $124.3 million, primarily to fund an
increase in loans held for sale, offset in part by cash provided from financing
activities of $281.4 million (primarily from an increase in deposits).

During the first nine months of 2003, cash and cash equivalents decreased by
$5.4 million, or 16%, to $29.4 million. This decrease was the net result of cash
used in net loan origination and other investing activities of $122.8 million
and cash used in operating activities of $61.5 million, offset in part by cash
provided from financing activities of $178.9.


CAPITAL RESOURCES

In the first nine months of 2004, total shareholders' equity increased $12.2
million, or 11%, to $122.1 million. Earnings, net of cash dividends declared on
common stock, contributed $11.1 million to shareholders' equity during this nine
month period. The sale or issuance of common stock through the dividend
reinvestment plan, the employee stock purchase plan, and the employee stock
option plan contributed an additional $1.6 million to shareholders' equity in
the first nine months of 2004, including tax benefits realized by Southwest
relating to option exercises. Accumulated comprehensive income (loss),
consisting of net unrealized gains (losses) on investment securities available
for sale (net of tax), was $(193,000) at September 30, 2004 compared to $360,000
at December 31, 2003.


                                       24


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. At September 30, 2004,
Southwest exceeded all applicable capital requirements, having a total
risk-based capital ratio of 13.85%, a Tier I risk-based capital ratio of 10.68%,
and a leverage ratio of 8.75%. As of September 30, 2004, 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 of the bank as a "well-capitalized" institution under
these regulations does not constitute a recommendation or endorsement of
Stillwater National by Federal bank regulators. SNB Wichita began operating in
November 2003 and has not yet received notification from the Office of Thrift
Supervision concerning its capital position.

Southwest declared a dividend of $0.07 per common share payable on October 1,
2004 to shareholders of record as of September 17, 2004.


EFFECTS OF INFLATION

The unaudited consolidated financial statements and related unaudited
consolidated financial data presented herein have been prepared in accordance
with accounting principles generally accepted in the United States of America
and practices within the banking industry which require the measurement of
financial position and operating results in terms of historical dollars without
considering fluctuations 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 do the effects of general levels of inflation.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Management has determined that no additional disclosures are necessary to assess
changes in information about market risk that have occurred since December 31,
2003.


CONTROLS AND PROCEDURES

Southwest's management, under the supervision and with the participation of its
Chief Executive Officer and the Chief Financial Officer, evaluated, as of the
last day of the period covered by this report, the effectiveness of the design
and operation of Southwest's disclosure controls and procedures, as defined in
Rule 13a-15 under the Securities Exchange Act of 1934. Based on that evaluation,
the Chief Executive Officer and Chief Financial Officer concluded that
Southwest's disclosure controls and procedures were adequate. There were no
significant changes in Southwest's internal controls over financial reporting
(as defined in Rule 13a-15 under the Securities Exchange Act of 1934) during the
nine months ended September 30, 2004, that have materially affected, or are
reasonably likely to materially affect, Southwest's internal controls over
financial reporting.


NON-GAAP FINANCIAL MEASURES

None of the financial measures used in this report are defined as non-GAAP
financial measures under federal securities regulations. Other banking
organizations, however, may present such non-GAAP financial measures, which
differ from measures based upon accounting principles generally accepted in the
United States. For example, such non-GAAP measures may exclude certain income or
expense items in calculating operating income or efficiency ratios, or may
increase yields and margins to reflect the benefits of tax-exempt
interest-earning assets. Accordingly, some of the measures used in this report
may not be directly comparable with non-GAAP measures used by some other
financial institutions.
