                             BANCFIRST CORPORATION
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (Unaudited)
                 (Dollars in thousands, except per share data)

(1)  GENERAL

     The accompanying consolidated financial statements include the accounts of
BancFirst Corporation, BFC Capital Trust I, Century Life Assurance Company,
Council Oak Partners, LLC, BancFirst and its subsidiaries, and First Southwest
Bank. All significant intercompany accounts and transactions have been
eliminated. Assets held in a fiduciary or agency capacity are not assets of the
Company and, accordingly, are not included in the consolidated financial
statements.

     The unaudited interim financial statements contained herein reflect all
adjustments which are, in the opinion of management, necessary to provide a fair
statement of the financial position and results of operations of the Company for
the interim periods presented. All such adjustments are of a normal and
recurring nature. There have been no significant changes in the accounting
policies of the Company since December 31, 2000, the date of the most recent
annual report. Certain amounts in the 2000 financial statements have been
reclassified to conform to the 2001 presentation.

     The preparation of financial statements in conformity with generally
accepted accounting principles inherently involves the use of estimates and
assumptions that affect the amounts reported in the financial statements and the
related disclosures. Such estimates and assumptions may change over time and
actual amounts may differ from those reported.

(2)  RECENT ACCOUNTING PRONOUNCEMENTS

     The Financial Accounting Standards Board (the "FASB") Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities", as amended by Statements 137 and 138, was adopted by
the Company on January 1, 2001. This Statement established accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts, and for hedging activities. It requires
that an entity recognize all derivatives as either assets or liabilities in the
statement of financial position and measure those financial instruments at fair
value. The accounting for changes in the fair value of a derivative instrument
depends on the intended use of the derivative and its resulting designation. The
adoption of this standard did not have a material effect on the Company's
consolidated financial statements.

     In September 2000, the FASB issued Statement of Financial Accounting
Standards No. 140, "Accounting for Transfers and Servicing of Financial Assets
and Extinguishments of Liabilities -A Replacement of FASB Statement No. 125".
This Statement is effective for transfers occurring after March 31, 2001 and for
disclosures relating to securitization transactions and collateral for fiscal
years ending after December 15, 2000. The Company does not expect the adoption
of this standard will have material effect on its consolidated financial
statements.

     In February 2001, the FASB issued a revised exposure draft for a proposed
Statement of Financial Accounting Standards entitled "Business Combinations and
Intangible Assets - Accounting for Goodwill." The proposed Statement would
prohibit the use of the pooling of interests method of accounting for business
combinations for transactions initiated after issuance of the final Statement.
It would also eliminate amortization of goodwill acquired in a business
combination and would establish a new method of testing goodwill for impairment.
Under this new standard, goodwill would be reviewed for impairment when an event
or series of events occur indicating that the goodwill might be impaired.
Goodwill impairment losses would be aggregated and presented as a separate line
item in the operating section of the income statement. If adopted, the proposed
Statement would have a material effect on the consolidated financial statements
of the Company by eliminating goodwill amortization from its income statement
and from the calculations of net income per share.

                                       5


(3)  RECENT DEVELOPMENTS; MERGERS, ACQUISITIONS AND DISPOSALS

     In March 2000, BancFirst Corporation became a financial holding company
under the new Gramm-Leach-Bliley financial services modernization law. This will
allow the Company to expand into new financial activities such as insurance
underwriting, securities underwriting and dealing, and mutual fund distribution.

     In October 2000, BancFirst Corporation completed the acquisition of First
Southwest Corporation of Frederick, Oklahoma ("First Southwest") which had total
assets of approximately $118,000. All of the outstanding shares of First
Southwest common stock were exchanged for 266,681 shares of BancFirst
Corporation common stock and approximately $4,335 of cash. The acquisition was
accounted for as a purchase. Accordingly, the effects of the acquisition are
included in the Company's consolidated financial statements from the date of the
acquisition forward. Total intangible assets of $4,279 were recorded for the
purchase. The acquisition did not have a material effect on the results of
operations of the Company for 2000.

     In January 2001, BancFirst Corporation completed the acquisition of 75% of
the outstanding common stock of Century Life Assurance Company ("Century Life")
from Pickard Limited Partnership, a Rainbolt family partnership. Century Life
underwrites credit life insurance, credit accident and health insurance, and
ordinary life insurance. The Rainbolt family is the largest shareholder of
BancFirst Corporation and two members of the family are the Chairman and the CEO
of BancFirst Corporation. The purchase price was $5,429. At December 31, 2000,
Century Life had total assets of $22,964 and total stockholders' equity of
$6,956. The acquisition was accounted for as a book value purchase. Accordingly,
the acquisition was recorded based on the book value of Century Life and the
effects of the acquisition are included in the Company's consolidated financial
statements from the date of the acquisition forward. The acquisition is not
expected to have a material effect on the results of operations of the Company
for 2001.

     The Company's loans are mostly to customers within Oklahoma and over half
of the loans are secured by real estate. Credit risk on loans is managed through
limits on amounts loaned to individual borrowers, underwriting standards and
loan monitoring procedures. The amounts and types of collateral obtained to
secure loans are based upon the Company's underwriting standards and
management's credit evaluation. Collateral varies, but may include real estate,
equipment, accounts receivable, inventory, livestock and securities. The
Company's interest in collateral is secured through filing mortgages and liens,
and in some cases, by possession of the collateral. The amount of estimated loss
due to credit risk in the Company's loan portfolio is provided for in the
allowance for loan losses. The amount of the allowance required to provide for
all existing losses in the loan portfolio is an estimate based upon evaluations
of loans, appraisals of collateral and other estimates which are subject to
rapid change due to changing economic conditions and the economic prospects of
borrowers. It is reasonably possible that a material change could occur in the
estimated allowance for loan losses in the near term.

     Changes in the allowance for loan losses are summarized as follows:

(8)  CAPITAL

     The Company is subject to risk-based capital guidelines issued by the Board
of Governors of the Federal Reserve System. These guidelines are used to
evaluate capital adequacy and involve both quantitative and qualitative
evaluations of the Company's assets, liabilities, and certain off-balance-sheet
items calculated under regulatory practices. Failure to meet the minimum capital
requirements can initiate certain mandatory or discretionary actions by the
regulatory agencies that could have a direct material effect on the Company's
financial statements. The required minimums and the Company's respective ratios
are shown below.

Total capital ratio      8.00%            12.42%        12.40%         12.50


     To be "well capitalized" under federal bank regulatory agency definitions,
a depository institution must have a Tier 1 ratio of at least 6%, a combined
Tier 1 and Tier 2 ratio of at least 10%, and a leverage ratio of at least 5%. As
of December 31, 2000 and 1999, BancFirst was considered to be "well
capitalized". There are no conditions or events since the most recent
notification of BancFirst's capital category that management believes would
change its category.

(9)  STOCK REPURCHASE PLAN

     In November 1999, the Company adopted a new Stock Repurchase Program (the
"SRP") authorizing management to repurchase up to 300,000 shares of the
Company's common stock. The SRP may be used as a means to increase earnings per
share and return on equity, to purchase treasury stock for the exercise of stock
options or for distributions under the Deferred Stock Compensation Plan, to
provide liquidity for optionees to dispose of stock from exercises of their
stock options, and to provide liquidity for shareholders wishing to sell their
stock. The timing, price and amount of stock repurchases under the SRP may be
determined by management and must be approved by the Company's Executive
Committee. At March 31, 2001 there are 106,105 shares remaining that can be
repurchased under the SRP. Below is a summary of the shares repurchased under
the program.

     The financial information for each business unit is presented on the basis
used internally by management to evaluate performance and allocate resources.
The Company utilizes a transfer pricing system to allocate the benefit or cost
of funds provided or used by the various business units. Certain revenues
related to other financial services are allocated to the banks whose customers
receive the services and, therefor, are not reflected in the income for other
financial services. Certain services provided by the support group to other
business units, such as item processing, are allocated at rates approximating
the cost of providing the services. Eliminations are adjustments to consolidate
the business units and companies.

Item 2.   Management's Discussion and Analysis of Financial Condition and
          Results of Operations.

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


SUMMARY

     Net income for the first quarter ended March 31, 2001 was $7.15 million, up
from $6.16 million for the first quarter of 2000. Diluted net income per share
was $0.85, a 13.3% increase from $0.75 for the first quarter of 2000.

     Total assets at March 31, 2001 was $2.68 billion, up $106 million from
December 31, 2000 and $298 million from March 31, 2000. The asset growth was due
in part to the acquisition of First Southwest Corporation of Frederick, Oklahoma
("First Southwest") in October 2000, which added approximately $118 million of
assets, and the purchase of 75% of Century Life Assurance Company ("Century
Life"), which added approximately $23 million of assets. Stockholders' equity
was $206 million at March 31, 2001, an increase of $9.4 million compared to
December 31, 2000, and $38.4 million compared to March 31, 2000.

     In January 2001, BancFirst Corporation completed the purchase of 75% of the
outstanding common stock of Century Life from Pickard Limited Partnership, a
Rainbolt family partnership. Century Life underwrites credit life insurance,
credit accident and health insurance, and ordinary life insurance. The Rainbolt
family is the largest shareholder of BancFirst Corporation and two members of
the family are the Chairman and the CEO of BancFirst Corporation. The purchase
price was $5.43 million. At December 31, 2000, Century Life had total assets of
$23 million and total stockholders' equity of $6.96 million. The acquisition was
accounted for as a book value purchase. Accordingly, the acquisition was
recorded based on the book value of Century Life and the effects of the
acquisition are included in the Company's consolidated financial statements from
the date of the acquisition forward. The acquisition is not expected to have a
material effect on the results of operations of the Company for 2001.
RESULTS OF OPERATIONS

     Net interest income increased $1.48 million compared to the first quarter
of 2000 due to growth in earning assets. Average net earning assets increased
$69.2 million from the first quarter of 2000. Net interest spread for the first
quarter of 2001 decreased to 3.65% from 3.96% for the first quarter of 2000, and
net interest margin for the first quarter of 2001 decreased to 4.59% from 4.77%
for the first quarter of 2000. The lower net interest spread and net interest
margin are the product of falling interest rates and a relatively flat to
inverted yield curve.

     The Company provided $332,000 for loan losses in the first quarter,
compared to $1.29 million for the first quarter of 2000. The higher provisions
in 2000 were due to loan growth and increases in classified and nonperforming
loans. Net loan charge-offs were $391,000 for the first quarter of 2001,
compared to $271,000 for the first quarter of 2000. The net charge-offs
represent annualized rates of only 0.10% and 0.08% of average total loans for
the first quarter of 2001 and 2000, respectively.

     Noninterest income increased $1.15 million, or 15.8%, compared to the first
quarter of 2000. Noninterest expense increased $2.17 million, or 10.5%, compared
to the first quarter of 2000. These increases were due in part to the
acquisition of First Southwest.

     Income tax expense increased $415,000 compared to the first quarter of 2000
due to higher taxable income. The effective tax rate on income before taxes was
35.30%, down from 36.16% in the first quarter of 2000.

FINANCIAL POSITION

     Federal funds sold increased $129 million from December 31, 2000 and $124
million from March 31, 2000 due to increased liquidity from deposit growth and
decreases in the balance of securities.

     Total securities decreased $11.8 million compared to December 31, 2000 and
$43.2 million compared to March 31, 2000. The size of the Company's securities
portfolio is a function of liquidity management and excess funds available for
investment. The Company has maintained a very liquid securities portfolio to
provide funds for loan growth. The net unrealized gain on securities available
for sale was $9.35 million at the end of the first quarter of 2001, compared to
a gain of $2.9 million at December 31, 2000 and a loss of $6.73 million at March
31, 2000. The average taxable equivalent yield on the securities portfolio for
the first quarter increased to 6.33% from 6.30% for the same quarter of 2000.

                                       12


     Total loans increased $11.5 million from December 31, 2000 and $187 million
from March 31, 2000, due to internal growth and approximately $80.2 million of
loans acquired with First Southwest. The allowance for loan losses decreased
$59,000 from year-end 2000 and increased $1.76 million from the first quarter of
2000. The acquisition of First Southwest added $1.48 million to the allowance.
The allowance as a percentage of total loans was 1.51%, 1.52% and 1.58% at March
31, 2001, December 31, 2000 and March 31, 2000, respectively. The allowance to
nonperforming and restructured loans at the same dates was 148.98%, 207.85% and
200.27%, respectively.

     Nonperforming and restructured assets totaled $19 million at March 31,
2001, compared to $14.3 million at December 31, 2000 and $13.6 million at March
31, 2000. The ratio of nonperforming and restructured assets to total assets
increased to 0.71% at March 31, 2000, compared to 0.56% at December 31, 2000 and
0.57% at March 31, 2000, due mainly to an increase in past due loans. It is
reasonable to expect nonperforming loans and loan losses to rise over time to
historical norms as a result of economic and credit cycles.

   Total deposits increased $80.1 million compared to December 31, 2000, and
$232 million compared to March 31, 2000. The increase in deposits is the result
of internal growth and the acquisition of First Southwest, which added
approximately $105 million in deposits. The Company's deposit base continues to
be comprised substantially of core deposits, with large denomination
certificates of deposit being only 14.1% of total deposits at March 31, 2001.

     Short-term borrowings decreased $2.4 million from December 31, 2000 and
increased $11.3 million from March 31, 2000. Fluctuations in short-term
borrowings are a function of federal funds purchased from correspondent banks,
customer demand for repurchase agreements and liquidity needs of the bank.

     Long-term borrowings decreased $674,000 from year-end 2000 and $1.37
million from the first quarter of 2000 due to payments on Federal Home Loan Bank
borrowings. The Company uses these borrowings primarily to match-fund long-term
fixed-rate loans.

     Stockholders' equity increased to $206 million from $197 million at year-
end 2000 and $168 million at March 31, 2000, as a result of accumulated earnings
and stock issued in the First Southwest acquisition. Average stockholders'
equity to average assets for the quarter was 7.64%, compared to 7.09% for the
first quarter of 2000. The Company's leverage ratio and total risk-based capital
ratio were 7.58% and 12.42%, respectively, at March 31, 2001, well in excess of
the regulatory minimums.
