                                     PART I

ITEM 1. BUSINESS

General

         Southwest is a financial holding company headquartered in Stillwater,
Oklahoma. Southwest provides commercial and consumer banking services through
its banking subsidiaries, Stillwater National Bank & Trust Company ("Stillwater
National") and SNB Bank of Wichita ("SNB Wichita") and management consulting
services through Business Consulting Group, Inc. and Healthcare Strategic
Support, Inc. Southwest was organized in 1981 as the holding company for
Stillwater National, which was chartered in 1894. Southwest is registered as a
bank holding company pursuant to the Bank Holding Company Act of 1956, as
amended (the "Holding Company Act"). As such, Southwest is subject to
supervision and regulation by the Board of Governors of the Federal Reserve
System (the "Federal Reserve"). Southwest became a financial holding company
during 2000 pursuant to the Holding Company Act. Stillwater National is a
national bank subject to supervision and regulation by the Office of the
Comptroller of the Currency (the "OCC"). SNB Wichita, headquartered in Wichita,
Kansas, is a federal savings bank chartered in November 2003 and subject to
supervision and regulation by the Office of Thrift Supervision ("OTS"). The
deposit accounts of Southwest's banking subsidiaries are insured by the by the
Federal Deposit Insurance Corporation (the "FDIC") to the maximum permitted by
law.

Products and Services

         Southwest offers a wide variety of commercial and consumer lending and
deposit services. Southwest has developed internet banking services, called SNB
DirectBanker(R), for consumer and commercial customers, a highly automated
lockbox, imaging and information service for commercial customers called
"Business Mail Processing," and a deposit product that automatically sweeps
excess funds from commercial demand deposit accounts and invests them in
short-term borrowings ("Sweep Repurchase Agreements"). The commercial loans
offered by Southwest include (i) commercial real estate loans, (ii) working
capital and other commercial loans, (iii) construction loans, and (iv) Small
Business Administration ("SBA") guaranteed loans. Consumer lending services
include (i) government-guaranteed student loans, (ii) residential real estate
loans and mortgage banking services, and (iii) personal lines of credit and
other installment loans. Southwest also offers deposit and personal banking
services, including (i) commercial deposit services such as Business Mail
Processing, commercial checking, money market, and other deposit accounts, and
(ii) retail deposit services such as certificates of deposit, money market
accounts, checking accounts, NOW accounts, savings accounts and automatic teller
machine ("ATM") access. Trust services, personal brokerage and credit cards are
offered through independent institutions.

Strategic Focus

         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. This philosophy has led to the development of a line of deposit and
lending products that responds to customer needs for speed, efficiency, and
information. These include Southwest's Sweep Repurchase Agreements, Business
Mail Processing, and SNB DirectBanker(R) and other internet banking products,
which complement Southwest's more traditional banking products. Southwest also
emphasizes marketing to highly educated, professional and business persons in
its markets. Southwest seeks to build close relationships with businesses,
professionals and their principals and to service their banking needs throughout
their business development and professional lives.

Organization

         Southwest's business operations are conducted through four operating
segments that include Oklahoma banking, Other states banking re, Secondary
market segment consisting of student lending and residential mortgage lending
services, and an "Other" segment that includes support, control, , and funding.
The organizational structure is designed to facilitate high customer service,
prompt response, efficiency, and appropriate, uniform credit standards and other
controls.

         Regional Divisions. The regional operating segments include Oklahoma
Banking, which includes the Stillwater division, the Central Oklahoma division,
based in Oklahoma City, and the Tulsa division; and Other States Banking, which
includes the Texas division, based in metropolitan Dallas, and the Kansas
Division, based in Wichita. The Stillwater division serves the Stillwater market
as a full-service community bank emphasizing both commercial and consumer
lending. The other four divisions pursue a more focused marketing strategy,
targeting managers, professionals, and businesses for lending, and offering more
specialized services. All of the regional divisions focus on commercial and
consumer financial services to local businesses and their senior employees and
to other managers and professionals living and working in Southwest's market
areas. Southwest has a high-service philosophy. Loan officers often meet at the
customer's home or place of business to close loans. Third-party courier
services often are used to collect commercial deposits.

         Secondary Market Segment. Southwest manages its mortgage and student
lending operations through its home office. Southwest markets its student
lending program directly to financial aid directors at colleges and universities
throughout the United States. Southwest also originates first mortgage loans for
sale to the Federal National Mortgage Association ("FNMA") or private investors.
Servicing on these loans may be released in connection with the sale.

         Support and Control Functions. Support and control functions are
centralized, although each regional division has support and control personnel.
Southwest's philosophy of customer service extends to its support and control
functions. Southwest manages and offers products that are technology based, or
that otherwise are more efficiently offered centrally, through its home office.
These include products that are marketed through the regional offices, such as
Southwest's internet banking product for commercial and retail customers (SNB
DirectBanker(R)), commercial information and item processing services (Business
Mail Processing), , and products marketed and managed directly by central staff,
such as cash dispensing machines. Southwest's technology products are marketed
both to existing customers and to help develop new customer relationships. Use
of these products by customers enables Southwest to serve its customers more
effectively, use its resources more efficiently, and increase fee income.

         For additional information regarding Southwest's operating segments,
please see "Note 16. Operating Segments" to the Consolidated Financial
Statements on page 45-46 of the Annual Report.

Banking Offices

         Banking Offices. Southwest has nine full-service banking offices, three
located in Stillwater, two located in Tulsa, Oklahoma, and one each in Oklahoma
City and Chickasha, Oklahoma, Frisco, Texas, and Wichita, Kansas; loan
production offices on the campuses of the University of Oklahoma Health Sciences
Center and Oklahoma State University-Tulsa; a marketing presence in the Student
Union at Oklahoma State University-Stillwater; and on the Internet, through SNB
DirectBanker(R). See "Item 2. Properties." Before 1999, laws of the State of
Oklahoma limited the number and location of de novo branches that a financial
institution could establish. Southwest has developed and continues to pursue a
business strategy that does not rely on an extensive branch network. National
banks in Oklahoma now have broad ability to establish de novo branches anywhere
in the state. Southwest established its interstate offices in Frisco, Texas and
Wichita, Kansas in 2002. SNB Wichita opened on the site of the Wichita loan
production office in 2003.

Regulation, Supervision, and Governmental Policy

         Following is a brief summary of certain statutes and regulations that
significantly affect Southwest and its banking subsidiaries. A number of other
statutes and regulations affect Southwest, Stillwater National, and SNB Wichita
but are not summarized below. Although Stillwater National and SNB Wichita have
different primary federal banking regulators, many of the rules that govern them
are substantially the same. Where practical, the rules for both banks are
discussed together below. For ease of reference the term "banks" is used below
to include national banks and state chartered banks ("commercial banks") and
federal savings banks and saving associations, unless other wise indicated.


                                       2
<PAGE>

         Bank Holding Company Regulation. Southwest is registered as a bank
holding company under the Holding Company Act and, as such, is subject to
supervision and regulation by the Federal Reserve. As a bank holding company,
Southwest is required to furnish to the Federal Reserve annual and quarterly
reports of its operations and additional information and reports. Southwest is
also subject to regular examination by the Federal Reserve.

         Under the Holding Company Act, a bank holding company must obtain the
prior approval of the Federal Reserve before (i) acquiring direct or indirect
ownership or control of any class of voting securities of any commercial bank or
bank holding company if, after the acquisition, the bank holding company would
directly or indirectly own or control more than 5% of the class; (2) acquiring
all or substantially all of the assets of another commercial bank or bank
holding company; or (3) merging or consolidating with another bank holding
company.

         Under the Holding Company Act, any company must obtain approval of the
Federal Reserve prior to acquiring control of Southwest or its banking
subsidiaries. For purposes of the Holding Company Act, "control" is defined as
ownership of more than 25% of any class of voting securities, the ability to
control the election of a majority of the directors, or the exercise of a
controlling influence over management or policies.

         The federal Change in Bank Control Act and the related regulations of
the Federal Reserve require any person or persons acting in concert (except for
companies required to make application under the Holding Company Act), to file a
written notice with the Federal Reserve before the person or persons acquire
control of Southwest or its banking subsidiaries. The Change in Bank Control Act
defines "control" as the direct or indirect power to vote 25% or more of any
class of voting securities or to direct the management or policies of a bank
holding company or an insured bank.

         The Holding Company Act also limits the investments and activities of
bank holding companies. In general, a bank holding company is prohibited from
acquiring direct or indirect ownership or control of more than 5% of the voting
shares of a company that is not a bank or a bank holding company or from
engaging directly or indirectly in activities other than those of banking,
managing or controlling commercial banks, providing services for its
subsidiaries, non-bank activities that are closely related to banking (including
ownership and control of a savings bank or savings association), and other
financially related activities. However, bank holding companies such as
Southwest that qualify as financial holding companies under the Holding Company
Act also may engage in a broad range of additional non-bank activities.
Southwest qualified as a financial holding company in 2000.

         The activities of Southwest are subject to these legal and regulatory
limitations under the Holding Company Act and Federal Reserve regulations.
Non-bank and financially related activities of bank holding companies, including
companies that become financial holding companies, also may be subject to
regulation and oversight by regulators other than the Federal Reserve.

         The Federal Reserve also has the power to order a holding company or
its subsidiaries to terminate any activity, or to terminate its ownership or
control of any subsidiary, when it has reasonable cause to believe that the
continuation of such activity or such ownership or control constitutes a serious
risk to the financial safety, soundness, or stability of any banking subsidiary
of that holding company.

         The Federal Reserve has adopted guidelines regarding the capital
adequacy of bank holding companies, which require bank holding companies to
maintain specified minimum ratios of capital to total assets and capital to
risk-weighted assets. See "Regulatory Capital Requirements."

         The Federal Reserve has the power to prohibit dividends by bank holding
companies if their actions constitute unsafe or unsound practices. The Federal
Reserve has issued a policy statement on the payment of cash dividends by bank
holding companies, which expresses the Federal Reserve's view that a bank
holding company should pay cash dividends only to the extent that the company's
net income for the past year is sufficient to cover both the cash dividends and
a rate of earnings retention that is consistent with the company's capital
needs, asset quality, and overall financial condition.

         National Bank Regulation. As a national bank, Stillwater National is
subject to the primary supervision of the OCC under the National Bank Act. The
prior approval of the OCC is required for a national bank to establish or
relocate an additional branch office or to engage in any merger, consolidation,
or significant purchase or sale of assets.


                                       3

         Before 1999, laws of the State of Oklahoma severely limited the number
and location of de novo branches that a national bank could establish. National
banks in Oklahoma now have broad ability to establish de novo branches anywhere
in the state as a result of changes in state laws enacted in 1999, and
interpretations of those laws by the OCC.

         The OCC regularly examines the operations and condition of Stillwater
National, including but not limited to its capital adequacy, reserves, loans,
investments, and management practices. These examinations are for the protection
of Stillwater National's depositors and the deposit insurance funds administered
by the FDIC. In addition, Stillwater National is required to furnish quarterly
and annual reports to the OCC. The OCC's enforcement authority includes the
power to remove officers and directors and the authority to issue
cease-and-desist orders to prevent a national bank from engaging in unsafe or
unsound practices or violating laws or regulations governing its business.

         No national bank may pay dividends from its paid-in capital. All
dividends must be paid out of current or retained net profits, after deducting
reserves for losses and bad debts. The National Bank Act further restricts the
payment of dividends out of net profits by prohibiting a national bank from
declaring a dividend on its shares of common stock until the surplus fund equals
the amount of capital stock or, if the surplus fund does not equal the amount of
capital stock, until one-tenth of a national bank's net profits for the
preceding half year in the case of quarterly or semi-annual dividends, or the
preceding two half-year periods in the case of annual dividends, are transferred
to the surplus fund.

         The approval of the OCC is required prior to the payment of a dividend
if the total of all dividends declared by a national bank in any calendar year
would exceed the total of its net profits for that year combined with its
retained net profits for the two preceding years, less any required transfers to
surplus or a fund for the retirement of any preferred stock. In addition,
Stillwater National is prohibited by federal statute from paying dividends or
making any other capital distribution that would cause Stillwater National to
fail to meet its regulatory capital requirements. Further, the OCC also has
authority to prohibit the payment of dividends by a national bank when it
determines that their payment would be an unsafe and unsound banking practice.

         Federal Savings Bank Regulation. As a federal savings bank, SNB Wichita
is subject to the primary supervision of the OTS. The prior approval of the OTS
is required for SNB Wichita to establish or relocate a branch office or to
engage in any merger, consolidation, or significant purchase or sale of assets.
The OTS examines the operations and condition of SNB Wichita, including, but not
limited to, its capital adequacy, reserves, loans, investments, and management
practices. These examinations are for the protection of SNB Wichita's depositors
and the deposit insurance funds administered by the FDIC. In addition, SNB
Wichita is required to furnish quarterly and annual reports to the OTS. The OTS
enforcement authority includes the power to remove officers and directors and
the authority to issue cease-and-desist orders to prevent a federal savings bank
from engaging in unsafe or unsound practices or violating laws or regulations
governing its business.

         In general, OTS regulations permit federal savings banks to branch in
any state or states of the United States and its territories.

         A federal savings bank that does not meet the Qualified Thrift Lender
("QTL") test must either convert to a national bank charter or comply with the
following restrictions on its operations: (i) the institution may not engage in
any new activity or make any new investment, directly or indirectly, unless such
activity or investment is permissible for a national bank; (ii) the branching
powers of the institution shall be restricted to those of a national bank; and
(iii) payment of dividends by the institution shall be subject to the rules
regarding payment of dividends by a national bank. Upon the expiration of three
years from the date the institution ceases to be a QTL, it must cease any
activity and not retain any investment not permissible for a national bank and a
federal savings bank. To qualify as a QTL, a federal savings bank must either
qualify as a "domestic building and loan association" under the Internal Revenue
Code or maintain at least 65% of its "portfolio assets" in Qualified Thrift
Investments. Portfolio assets are defined as total assets less intangibles, the
value of property used by a federal savings bank in its business and liquidity
investments in an amount not exceeding 20% of assets. Qualified Thrift
Investments consist of (i) loans, equity positions or securities related to
domestic, residential real estate or manufactured housing and educational, small
business and credit card loans; and (ii) subject to an aggregate 20% of
portfolio assets limit, shares of stock in the FHLMC and the FNMA, loans for
personal, family, household purposes, 50% of the dollar amount of residential
mortgage loans originated and sold within 90 days of origination, and 200% of a
federal savings bank's investments in loans to finance "starter homes" and loans
for construction, development or improvement of housing and community service
facilities or for financing small businesses in "credit-needy" areas. In order
to maintain QTL status, the federal savings bank must maintain a weekly


                                       4
<PAGE>


average percentage of Qualified Thrift Investments to portfolio assets equal to
65% on a monthly average basis in nine out of 12 months. A federal savings bank
that fails to maintain QTL status will be permitted to requalify once, and if it
fails the QTL test a second time, it will become immediately subject to all
penalties as if all time limits on such penalties had expired. At December 31,
2003, approximately 83.23% of SNB Wichita's assets were invested in Qualified
Thrift Investments, which were in excess of the percentage required to qualify
it under the QTL test.

         Under regulations of the OTS, federal savings banks must submit notice
to the OTS prior to making a capital distribution (which includes dividends,
stock repurchases and amounts paid to stockholders in another institution in a
cash merger) if (a) they would not be well capitalized after the distribution,
(b) the distribution would result in the retirement of any of the federal
savings bank's common or preferred stock or debt counted as its regulatory
capital, or (c) the federal savings bank is a subsidiary of a holding company. A
federal savings bank must make application to the OTS to pay a capital
distribution if (x) the federal savings bank would not be adequately capitalized
following the distribution, (y) the federal savings bank's total distributions
for the calendar year exceed the federal savings bank's net income for the
calendar year to date plus its net income (less distributions) for the preceding
two years, or (z) the distribution would otherwise violate applicable law or
regulation or an agreement with or condition imposed by the OTS. Under the OTS'
prompt corrective action regulations, SNB Wichita is also prohibited from making
any capital distributions if after making the distribution, SNB Wichita would
have: (i) a total risk-based capital ratio of less than 8.0%; (ii) a Tier 1
risk-based capital ratio of less than 4.0%; or (iii) a leverage ratio of less
than 4.0%.

         Limits on Loans to One Borrower. National banks and federal savings
banks generally are subject to the same loan to one borrower limits. With
certain limited exceptions, loans and extensions of credit outstanding to any
borrower (including certain related entities of the borrower) at any one time
may not exceed 15% of the unimpaired capital and surplus of the institution. A
national bank or federal savings bank may lend an additional amount, equal to
10% of unimpaired capital and surplus, if such loan is fully secured by readily
marketable collateral. Federal savings banks are additionally authorized to make
loans to one borrower, for any purpose, in an amount not to exceed $500,000 or,
by order of the Director of OTS, in an amount not to exceed the lesser of
$30,000,000 or 30% unimpaired capital and surplus to develop residential
housing, provided: (i) the purchase price of each single-family dwelling in the
development does not exceed $500,000; (ii) the federal savings bank is in
compliance with its regulatory capital requirements; (iii) the loans comply with
applicable loan-to-value requirements, and; (iv) the aggregate amount of loans
made under this authority does not exceed 150% of unimpaired capital and
surplus. The lending limits generally do not apply to purchase money mortgage
notes taken from the purchaser of real property acquired by federal savings
banks in satisfaction of debts previously contracted if no new funds are
advanced to the borrower and the federal savings bank is not placed in a more
detrimental position as a result of the sale. Certain types of loans are
exempted from the lending limits, including loans secured by in-bank deposits.

         Transactions with Affiliates. Banks are subject to restrictions imposed
by federal law on extensions of credit to, and certain other transactions with,
Southwest and other affiliates, and on investments in their stock or other
securities. These restrictions prevent Southwest and its nonbanking subsidiaries
from borrowing from Stillwater National or SNB Wichita unless the loans are
secured by specified collateral, and require those transactions to have terms
comparable to terms of arms-length transactions with third persons. In addition,
secured loans and other transactions and investments by Stillwater National or
SNB Wichita are generally limited in amount as to Southwest and as to any other
affiliate to 10% of Stillwater National's or SNB Wichita's capital and surplus
and as to Southwest and all other affiliates together to an aggregate of 20% of
the Stillwater National's or SNB Wichita's capital and surplus. Certain
exemptions to these limitations apply to extensions of credit by, and other
transactions between, Stillwater National or SNB Wichita and their subsidiaries.
These regulations and restrictions may limit Southwest's ability to obtain funds
from Stillwater National and SNB Wichita for its cash needs, including funds for
acquisitions and for payment of dividends, interest, and operating expenses.

         Real Estate Lending Guidelines. Under federal banking regulations,
banks must adopt and maintain written policies that establish appropriate limits
and standards for extensions of credit secured by liens or interests in real
estate or are made for the purpose of financing permanent improvements to real
estate. These policies must establish loan portfolio diversification standards;
prudent underwriting standards, including loan-to-value limits, that are clear
and measurable; loan administration procedures; and documentation, approval, and
reporting requirements. A bank's real estate lending policy must reflect
consideration of the Guidelines for Real Estate Lending Policies (the
"Guidelines") adopted by the federal banking regulators. The Guidelines, among
other things, call for internal loan-to-value limits for real estate loans that
are not in excess of the limits specified in the Guidelines. The Guidelines
state, however, that it may be appropriate in individual cases to originate or
purchase loans with loan-to-value ratios in excess of the supervisory
loan-to-value limits.

         Federal Deposit Insurance. The FDIC has established a risk-based
deposit insurance premium assessment system for banks. Under the system, the
assessment rate for an insured depository bank depends on the assessment risk
classification assigned to the bank by the FDIC, based upon the bank's capital
level and supervisory evaluations. Banks are assigned to one of three capital
groups -- well-capitalized, adequately capitalized, or undercapitalized -- based
on the data reported to regulators. Well-capitalized banks are banks satisfying
the following capital ratio standards: (i) total risk-based capital ratio of
10.0% or greater; (ii) Tier 1 risk-based capital ratio of 6.0% or greater; and
(iii) Tier 1 leverage ratio of 5.0% or greater. Adequately capitalized banks are
banks that do not meet the standards for well-capitalized banks but that satisfy
the following capital ratio standards: (i) total risk-based capital ratio of
8.0% or greater; (ii) Tier 1 risk-based capital ratio of 4.0% or greater; and
(iii) Tier 1 leverage ratio of 4.0% or greater. Banks that do not qualify as
either well-capitalized or adequately capitalized are deemed to be
undercapitalized. Within each capital group, banks are assigned to one of three
subgroups on the basis of supervisory evaluations by the bank's primary
supervisory authority and such other information as the FDIC determines to be
relevant to the bank's financial condition and the risk it poses to the deposit
insurance fund. Subgroup A consists of financially sound banks with only a few
minor weaknesses. Subgroup B consists of banks with demonstrated weaknesses
that, if not corrected, could result in significant deterioration of the bank
and increased risk of loss to the deposit insurance fund. Subgroup C consists of
banks that pose a substantial probability of loss to the deposit insurance fund
unless effective corrective action is taken. Stillwater National has been
informed that it is in the lowest-cost/best risk assessment category for the
first assessment period of 2004. SNB Wichita has not yet been assessed.

         Regulatory Capital Requirements. Federal regulators have established
guidelines for maintenance of appropriate levels of capital by bank holding
companies and banks. The regulations impose two sets of capital adequacy
requirements: minimum leverage rules, which require bank holding companies and
banks to maintain a specified minimum ratio of capital to total assets, and
risk-based capital rules, which require the maintenance of specified minimum
ratios of capital to "risk-weighted" assets.

         Federal banking regulations require bank holding companies and banks to
maintain a minimum leverage ratio of "Tier 1 capital" (as defined in the
risk-based capital guidelines discussed in the following paragraphs) to total
assets of 3.0%. The capital regulations state, however, that only the strongest
bank holding companies and banks, with composite examination ratings of 1 under
the rating system used by the federal banking regulators, would be permitted to
operate at or near this minimum level of capital. All other bank holding
companies and banks are expected to maintain a leverage ratio of at least 1% to
2% above the minimum ratio, depending on the assessment of an individual
organization's capital adequacy by its primary regulator. A bank holding company
or bank experiencing or anticipating significant growth is expected to maintain
capital well above the minimum levels. In addition, the Federal Reserve has
indicated that it also may consider the level of an organization's ratio of
tangible Tier 1 capital (after deducting all intangibles) to total assets in
making an overall assessment of capital. Under OTS capital regulations, federal
savings banks also must maintain "tangible" capital equal to 1.5% of adjusted
total assets. Tangible capital for OTS purposes is Tier 1 capital reduced by the
amount of all the federal savings bank's intangible assets except for limited
amounts of mortgage servicing rights.

         The federal risk-based capital rules of the require bank holding
companies and banks, to maintain minimum regulatory capital levels based upon a
weighting of their assets and off-balance sheet obligations according to risk.
The risk-based capital rules have two basic components: a core capital (Tier 1)
requirement and a supplementary capital (Tier 2) requirement. Core capital
consists primarily of common stockholders' equity, certain perpetual preferred
stock (noncumulative perpetual preferred stock with respect to national banks),
and minority interests in the equity accounts of consolidated subsidiaries; less
all intangible assets, except for certain mortgage servicing rights and
purchased credit card relationships. Supplementary capital elements include,
subject to certain limitations, the allowance for losses on loans and leases;
perpetual preferred stock that does not qualify as Tier 1 capital; long-term
preferred stock with an original maturity of at least 20 years from issuance;
hybrid capital instruments, including perpetual debt and mandatory convertible
securities; subordinated debt, intermediate-term preferred stock, and up to 45%
of pre-tax net unrealized gains on available for sale equity securities.

         The risk-based capital regulations assign balance sheet assets and
credit equivalent amounts of off-balance sheet obligations to one of four broad
risk categories based principally on the degree of credit risk associated with
the obligor. The assets and off-balance sheet items in the four risk categories
are weighted at 0%, 20%, 50% and 100%. These computations result in the total
risk-weighted assets.

         The risk-based capital regulations require all bank holding companies
and banks to maintain a minimum ratio of total capital to total risk-weighted
assets of 8%, with at least 4% as core capital. For the purpose of calculating
these ratios: (i) supplementary capital is limited to no more than 100% of core
capital; and (ii) the aggregate amount of certain types of supplementary capital
is limited. In addition, the risk-based capital regulations limit the allowance
for loan losses that may be included in capital to 1.25% of total risk-weighted
assets.

         The federal banking regulatory agencies have established a joint policy
regarding the evaluation of banks' capital adequacy for interest rate risk.
Under the policy, the assessment of a national bank's capital adequacy includes
an assessment of exposure to adverse changes in interest rates. The OCC has
determined to rely on its examination process for such evaluations rather than
on standardized measurement systems or formulas. A federal savings bank's
interest rate risk is measured in terms of the sensitivity of its "net portfolio
value" to changes in interest rates. A federal savings bank with more than
normal interest rate risk is required to deduct an interest rate risk component
equal to one-half of the excess of its measured interest rate risk over the
normal level from its total capital for purposes of determining its compliance
with the OTS risk-based capital guidelines. The federal banking regulators may
require federal savings banks that are found to have a high level of interest
rate risk exposure or weak interest rate risk management systems to take
corrective actions. Management believes its interest rate risk management
systems and its capital relative to its interest rate risk are adequate.

         Federal banking regulations also require banks with significant trading
assets or liabilities to maintain supplemental risk-based capital based upon
their levels of market risk. Neither Stillwater National nor SNB Wichita had any
trading assets or liabilities during 2003, 2002 or 2001, and were not required
to maintain such supplemental capital.

         The federal banking regulators have established regulations that
classify banks by capital levels and provide for various "prompt corrective
actions" to resolve the problems of any bank that fails to satisfy the capital
standards. Under these regulations, a well-capitalized bank is one that is not
subject to any regulatory order or directive to meet any specific capital level
and that has a total risk-based capital ratio of 10% or more, a Tier 1
risk-based capital ratio of 6% or more, and a leverage ratio of 5% or more. An
adequately capitalized bank is one that does not qualify as well-capitalized but
meets or exceeds the following capital requirements: a total risk-based capital
ratio of 8%, a Tier 1 risk-based capital ratio of 4%, and a leverage ratio of
either (i) 4% or (ii) 3% if the bank has the highest composite examination
rating. A bank that does not meet these standards is categorized as
undercapitalized, significantly undercapitalized, or critically
undercapitalized, depending on its capital levels. A f bank that falls within
any of the three undercapitalized categories established by the prompt
corrective action regulation is subject to severe regulatory sanctions. As of
December 31, 2003, Stillwater National and SNB Wichita were well-capitalized as
defined in applicable banking regulations.

         For information regarding Southwest's, Stillwater National's, and SNB
Wichita's compliance with their respective regulatory capital requirements, see
"Management's Discussion and Analysis -- Capital Resources" on page 15 of the
Annual Report, and, in the Notes to Consolidated Financial Statements in the
Annual Report "Note 6-Subordinated Debentures" on page 38 and "Note 9- Capital
Requirements" on pages 41-43.

         Supervision and Regulation of Mortgage Banking Operations. Southwest's
mortgage banking business is subject to the rules and regulations of the U.S.
Department of Housing and Urban Development ("HUD"), the Federal Housing
Administration ("FHA"), the Veterans' Administration ("VA"), and FNMA with
respect to originating, processing, selling and servicing mortgage loans. Those
rules and regulations, among other things, prohibit discrimination and establish
underwriting guidelines, which include provisions for inspections, and
appraisals, require credit reports on prospective borrowers, and fix maximum
loan amounts. Lenders such as Southwest are required annually to submit to FNMA,
FHA and VA financial statements, and each regulatory entity has its own
financial requirements. Southwest's affairs are also subject to examination by
the Federal Reserve, FNMA, FHA and VA at all times to assure compliance with the
applicable regulations, policies and procedures. Mortgage origination activities
are subject to, among others, the Equal Credit Opportunity Act, Federal
Truth-in-Lending Act, Fair Housing Act, Fair Credit Reporting Act, the National
Flood Insurance Act, and the Real Estate Settlement Procedures Act and related
regulations that prohibit discrimination and require the disclosure of certain
basic information to mortgagors concerning credit terms and settlement costs.
Southwest's mortgage banking operations also are affected by various state and
local laws and regulations and the requirements of various private mortgage
investors.

         Other Laws and Regulations. Some of the aspects of the lending and
deposit business of Stillwater National and SNB Wichita that are subject to
regulation by the Federal Reserve and the FDIC include reserve requirements and
disclosure requirements in connection with personal and mortgage loans and
deposit accounts. In addition, Stillwater National and SNB Wichita are subject
to numerous federal and state laws and regulations that include specific
restrictions and procedural requirements with respect to the establishment of
branches, investments, interest rates on loans, credit practices, the disclosure
of credit terms, and discrimination in credit transactions.

Competition

         Southwest encounters competition in seeking deposits and in obtaining
loan, cash management, investment and other customers. The level of competition
for deposits is high. Southwest's principal competitors for deposits are other
financial institutions, including other national banks, federal savings banks,
and credit unions. Competition among these institutions is based primarily on
interest rates and other terms offered, service charges imposed on deposit
accounts, the quality of services rendered, and the convenience of banking
facilities. Additional competition for depositors' funds comes from U.S.
Government securities, private issuers of debt obligations and suppliers of
other investment alternatives for depositors, such as securities firms.
Competition from credit unions has intensified in recent years as historic
federal limits on membership have been relaxed. Because federal law subsidizes
credit unions by giving them a general exemption from federal income taxes,
credit unions have a significant cost advantage over national banks and federal
savings banks, which are fully subject to federal income taxes. Credit unions
may use this advantage to offer rates that are highly competitive with those
offered by national banks and federal savings banks.

         Southwest also competes in its lending activities with other financial
institutions such as securities firms, insurance companies, credit unions, small
loan companies, finance companies, mortgage companies and other sources of
funds. Many of Southwest's nonbank competitors are not subject to the same
extensive federal regulations that govern bank holding companies and
federally-insured banks. As a result, such nonbank competitors have advantages
over Southwest in providing certain services. A number of the financial
institutions with which Southwest competes in lending, deposit, investment, cash
management and other activities are larger than Southwest or have a
significantly larger market share. The new offices in metropolitan Dallas and
Wichita compete for loans, deposits and other services against local and
nationally based financial institutions, many of which have much larger market
shares and widespread office networks. In recent periods, competition has
increased in Southwest's Oklahoma market areas as new entrants and existing
competitors have sought to more aggressively expand their loan and deposit
market share.

         The business of mortgage banking is highly competitive. Southwest
competes for loan originations with other financial institutions, such as
mortgage bankers, state and national banks, federal savings banks, credit unions
and insurance companies. Many of Southwest's competitors have financial
resources that are substantially greater than those available to Southwest.
Southwest competes principally by providing competitive pricing, by motivating
its sales force through the payment of commissions on loans originated, and by
providing high quality service to builders, borrowers, and realtors.

         The Holding Company Act permits the Federal Reserve to approve an
application of an adequately capitalized and adequately managed bank holding
company to acquire control of, or acquire all or substantially all of the assets
of, a commercial bank located in a state other than that holding company's home
state. The Federal Reserve may not approve the acquisition of a commercial bank
that has not been in existence for the minimum time period (not exceeding five
years) specified by the statutory law of the host state. The Holding Company Act
also prohibits the Federal Reserve from approving an application if the
applicant (and its depository institution affiliates) controls or would control
more than 10% of the insured deposits in the United States or 30% or more of the
deposits in the target commercial bank's home state or in any state in which the
target commercial bank maintains a branch. The Holding Company Act does not
affect the authority of states to limit the percentage of total insured deposits
in the state which may be held or controlled by a commercial bank or bank
holding company to the extent such limitation does not discriminate against
out-of-state commercial banks or bank holding companies. The State of Oklahoma
allows out-of-state financial institutions to establish branches in Oklahoma,
subject to certain limitations. Federal savings banks generally may establish
branches in any state, and bank holding companies may acquire federal savings
banks in any state, without regard to state law

         Financial holding companies may engage in banking as well as types of
securities, insurance, and other financial activities that had been prohibited
for bank holding companies under prior law. Financial institutions with or
without holding companies also are authorized to establish and operate financial
subsidiaries that may engage in most financial activities in which financial
holding companies may engage. Competition may increase as bank holding companies
and other large financial service companies take advantage of the new activities
and provide a wider array of products.

Employees

         As of December 31, 2003, Southwest employed 345 persons on a full-time
equivalent basis, including executive officers, loan and other banking officers,
branch personnel, and others. No employees of Southwest or any of its
consolidated subsidiaries are represented by a union or covered under a
collective bargaining agreement. Management of Southwest considers their
employee relations to be excellent.

         Southwest does not have any material amounts of investment securities
or other interest-earning assets, other than loans, that would have been
classified as nonperforming if such assets were loans, or which were recognized
by management as potential problem assets based upon known information about
possible credit problems of the borrower or issuer.

                          Investment Portfolio Maturity

         The following table shows the maturities, carrying value (amortized
cost for investment securities being held to maturity or estimated fair value
for investment securities available for sale), estimated fair market values and
average yields for Southwest's investment portfolio at December 31, 2003. Yields
are not presented on a tax-equivalent basis. Maturities of mortgage-backed
securities are based on expected maturities. Expected maturities will differ
from contractual maturities due to scheduled repayments and because borrowers on
the underlying mortgages may have the right to call or prepay obligations with
or without prepayment penalties. The securities of no single issuer (other than
the United States or its agencies), or in the case of securities issued by state
and political subdivisions, no source or group of sources of repayment,
accounted for more than 10% of shareholders' equity of Southwest at December 31,
2003.

         Potential Nonperforming Loans. 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 cause management to be uncertain as to the ability of
the borrowers to comply with the present loan repayment terms over the next six
months, amounted to approximately $37.8 million at December 31, 2003, compared
to $28.9 million at December 31, 2002, and $55.8 million at December 31, 2001.
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.

                   Allocation of the Allowance for Loan Losses

         Southwest's methodology for assessing the appropriateness of the
allowance includes determination of a formula allowance, specific allowances and
a general allowance. Additional information regarding this methodology, the
allowance for loan losses, and the related provision for loan losses is included
in the Annual Report on pages 10 and 11 under the caption "Provision for Loan
Losses," and in Note 1 on page 30 and Note 3 on page 34 . The following table
presents a five-year history for the allocation of the allowance for loan losses
along with the percentage of total loans and leases in each category (dollars in
thousands).When measured against the total allowance, the general allowance
decreased to 8.2% from 11.3% at December 31, 2002, and was 7.7% at December 31,
2001.

         Management believes that the allowance for loan losses is adequate.
However, its determination requires significant judgment, and estimates of
probable losses inherent in the loan portfolio can vary significantly from the
amounts actually observed. While management uses available information to
recognize probable losses, future additions to the allowance may be necessary
based on changes in the assets comprising the loan and lease portfolio and
changes in the financial condition of borrowers, such as may result from changes
in economic conditions. In addition, various regulatory agencies, as an integral
part of their examination process, and independent consultants engaged by
Southwest, periodically review the loan portfolio and allowance for loan losses.
Such review may result in recognition of additional provisions based on their
judgments of information available at the time of each examination.

                   Certificates of Deposit of $100,000 or More

         The following table indicates the amount of Southwest's certificates of
