                             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, BancFirst and its subsidiaries, and
First State Bank for 2000 and a portion of 1999 (representing the period since
acquisition). 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, 1999, the date of the most recent
annual report. Certain amounts in the 1999 financial statements have been
reclassified to conform to the 2000 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

      In June 1998, the Financial Accounting Standards Board (the "FASB") issued
Statement of Financial Accounting Standards No. 133, "Accounting for Derivative
Instruments and Hedging Activities." This Statement establishes 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. In
June 1999, the FASB issued Statement of Financial Accounting Standards No. 137,
"Accounting for Derivative Instruments and Hedging Activities - Deferral of the
Effective Date of FASB Statement No. 133 - an amendment of FASB Statement No.
133." This Statement defers the effective date of FASB Statement No. 133 to all
fiscal quarters of fiscal years beginning after June 15, 2000. The Company does
not expect that the adoption of this standard will have a material impact on its
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.

(3)   RECENT DEVELOPMENTS; MERGERS, ACQUISITIONS AND DISPOSALS

      In February 1999, the Company sold a branch in Anadarko, Oklahoma, which
had deposits of approximately $15,500. The sale resulted in a pretax gain of
approximately $900.

      In December 1999, the Company completed the purchase of certain assets and
assumption of certain liabilities of First State Bank of Oklahoma City,
Oklahoma. Under the terms of the agreement, the Company organized a new wholly-
owned bank under the First State Bank name. The new First State Bank acquired
approximately $106,000 of assets, assumed approximately $109,000 of liabilities,
and recorded $2,615 of intangible assets. The purchase and assumption 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. The acquisition did not have a material effect on the
results of the operations of the Company for 1999.

      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

                                       4


("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. 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 approximately $5.4 million. At December 31, 2000, Century Life had
total assets of $23 million and total stockholders' equity of $6.96 million. The
acquisition will be accounted for as a book value purchase. Accordingly, the
acquisition will be recorded based on the book value of Century Life and the
effects of the acquisition will be 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.

(4)   TENDER OFFER

      In June 1999, the Company completed a Dutch auction issuer tender offer
and purchased 1,186,502 shares of its common stock for the maximum offer price
of $38.00 per share. Cash on hand and two borrowings totaling $7,600 were used
to pay for the purchase of the stock. The two borrowings under a $12,000
revolving line of credit were at rates of 6.3% and 6.5%, and matured in July and
October 1999.

      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:

(9)   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.



                                        Minimum                 December 31,

      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.

(10)  STOCK REPURCHASE PLAN

      In November 1999, the Company adopted a new Stock Repurchase Program (the
"New SRP") authorizing management to repurchase up to 300,000 shares of the
Company's common stock. The New 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 New SRP may
be determined by management and must be approved by the Company's Executive
Committee. Below is a summary of the shares repurchased under the program.
