ITEM 1.  BUSINESS.

GENERAL

     BancFirst Corporation (the "Company") is an Oklahoma business corporation
and a bank holding company under Federal law.  It conducts virtually all of its
operating activities through its principal wholly-owned subsidiary, BancFirst
(the "Bank" or "BancFirst"), a state-chartered, Federal Reserve member bank
headquartered in Oklahoma City, Oklahoma. BancFirst Corporation also owns 100%
of the common securities of BFC Capital Trust I, a Delaware Business Trust
organized in January 1997, and at December 31, 1998 owned 100% of Kingfisher
Bank & Trust Co., an Oklahoma state-chartered bank.

     The Company was incorporated as United Community Corporation in July 1984
for the purpose of becoming a bank holding company.  In June 1985, it merged
with seven Oklahoma bank holding companies that had operated under common
ownership and the Company has conducted business as a bank holding company since
that time.  Over the next several years the Company acquired additional banks
and bank holding companies, and in November 1988 the Company changed its name to
BancFirst Corporation.  Effective April 1, 1989, the Company consolidated its 12
subsidiary banks and formed BancFirst.  BancFirst currently has 73 banking
locations serving 36 communities throughout Oklahoma.

     The Company's strategy focuses on providing a full range of commercial
banking services to retail customers and small to medium-sized businesses both
in the non-metropolitan trade centers of Oklahoma and the metropolitan markets
of Oklahoma City, Tulsa, Lawton, Muskogee, Norman and Shawnee.  The Company
operates as a "super community bank", managing its community banking offices on
a decentralized basis, which permits them to be responsive to local customer
needs.  Underwriting, funding, customer service and pricing decisions are made
by Presidents in each market within the Company's strategic parameters.  At the
same time, the Company generally has a larger lending capacity, broader product
line and greater operational efficiencies than its principal competitors in the
non-metropolitan market areas (which typically are independently-owned community
banks).  In the metropolitan markets served by the Company, the Company's
strategy is to focus on the needs of local businesses not served effectively by
larger institutions.

     The Bank maintains a strong community orientation by, among other things,
appointing selected members of the communities in which the Bank's branches are
located to a local consulting board that assists in introducing prospective
customers to the Bank and in developing or modifying products and services to
meet customer needs.  As a result of the development of broad banking
relationships with its customers and the convenience and service of the Bank's
multiple offices, the Bank's lending and investing activities are funded almost
entirely by core deposits.

     The Bank centralizes virtually all of its back office, support and
investment functions in order to achieve consistency and cost efficiencies in
the delivery of products and services.  The Bank centrally provides services
such as data processing, operations support, bookkeeping, accounting, loan
review, compliance and internal auditing to the Bank's community banking offices
to enhance their ability to compete effectively.  The Bank also provides certain
specialized financial services centrally that require unique expertise.  The
community banking offices assist the Bank in maintaining its competitive
position by actively participating in the development of new products and
services needed by their customers and in making desirable changes to existing
products and services.

     The Bank provides a wide range of retail and commercial banking services,
including: commercial, real estate, agricultural and consumer lending;
depository and funds transfer services; collections; safe deposit boxes; cash
management services; and other services tailored for both individual and
corporate customers.  The Bank also offers trust services and acts as executor,
administrator, trustee, transfer agent and in various other fiduciary
capacities.  Through Unitech, its operations division, the Bank provides, item
processing, research and other correspondent banking services to financial
institutions and governmental units.

     The Bank's primary lending activity is the financing of business and
industry in its market areas.  Its commercial loan customers are generally small
to medium-sized businesses engaged in light manufacturing, local wholesale and
retail trade, services, agriculture, and the energy industry.  Most forms of
commercial lending are offered, including commercial mortgages, other forms of
asset-based financing and working capital lines of credit.  In addition, the
Bank offers Small Business Administration ("SBA") guaranteed loans through
BancFirst Commercial Capital, a division established in 1991.

     The Bank's residential mortgage lending activities prior to 1992 consisted
primarily of short- to intermediate-term loans for purchasing personal
residences, or loans for commercial or consumer purposes secured by residential
mortgages.  In early 1992, the Bank established a mortgage loan department to
originate traditional mortgage loans through its network of banking locations
and sell such loans in the secondary market with the servicing released.

     

                                       3

     Consumer lending activities of the Bank consist of traditional forms of
financing for automobiles and other personal loans, and also residential
mortgage loans.  In addition, the Bank is one of Oklahoma's largest providers of
guaranteed student loans.

     The Bank's range of deposit services include checking accounts, NOW
accounts, savings accounts, money market accounts, club accounts, individual
retirement accounts and certificates of deposit.  Overdraft protection and
autodraft services are also offered.  Deposits of the Bank are insured by the
Bank Insurance Fund administered by the Federal Deposit Insurance Corporation
("FDIC").  In addition, certain Bank employees are licensed insurance agents
qualified to offer tax deferred annuities.

     Trust services offered through BancTrust, the Bank's trust division,
consist primarily of investment management and administration of trusts for
individuals, corporations and employee benefit plans.  Investment options
include collective equity and fixed income funds managed by BancTrust and
advised by a nationally recognized investment management firm.

     BancFirst has the following subsidiaries: BancFirst Investment Corporation,
a small business investment corporation; Citibanc Insurance Agency, Inc., a
credit life insurance agency, which in turn owns BancFirst Agency, Inc., a title
insurance agency; Lenders Collection Corporation, which is engaged in collection
of troubled loans assigned to it by BancFirst; and Express Financial Corporation
(formerly National Express Corporation), a money order company.  All of these
companies are Oklahoma corporations.

     The Company had approximately 1,280 full-time equivalent employees as of
December 31, 1998.  Its principal executive offices are located at 101 North
Broadway, Suite 200, Oklahoma City, Oklahoma 73102, telephone number (405) 270-
1086.

MARKET AREAS AND COMPETITION

     The banking environment in Oklahoma is very competitive.   The geographic
dispersion of the Company's banking locations presents several different levels
and types of competition.  In general, however, each location competes with
other banking institutions, savings and loan associations, personal loan finance
companies and credit unions within their respective market areas.  The
communities in which the Bank maintains offices are generally local trade
centers throughout Oklahoma.  The major areas of competition include interest
rates charged on loans, interest rates paid on deposits, levels of service
charges on deposits, completeness of product line and quality of service.

     Management believes the Company is in an advantageous competitive position
operating as a "super community bank."  Under this strategy, the Company
provides a broad line of financial products and services to small to medium-
sized businesses and consumers through full service community banking offices
with decentralized management, while achieving operating efficiency through
product standardization and centralization of processing and other functions.
Each full service banking office has senior management with significant lending
experience who exercise substantial autonomy over credit and pricing decisions,
subject to a tiered approval process for larger credits.  This decentralized
management approach, coupled with continuity of service by the same staff
members, enables the Bank to develop long-term customer relationships, maintain
high quality service and respond quickly to customer needs.  The majority of its
competitors in the non-metropolitan areas are much smaller, and neither offer
the range of products and services nor have the lending capacity of BancFirst.
In the metropolitan communities, the Company's strategy is to be more responsive
to, and more focused on, the needs of local businesses not served effectively by
larger institutions.

     Marketing to existing and potential customers is performed through a
variety of media advertising, direct mail and direct personal contacts.  The
Company monitors the needs of its customer base through its Product Development
Group, which develops and enhances products and services in response to such
needs.  Sales, customer service and product training are coordinated with
incentive programs to motivate employees to cross-sell the Bank's products and
services.

CONTROL OF THE COMPANY

     Affiliates of the Company beneficially own approximately 62% of the shares
of the Common Stock outstanding. Under Oklahoma law, holders of a majority of
the outstanding shares of Common Stock are able to elect all of the directors
and approve significant corporate actions, including business combinations.
Accordingly, the Affiliates have the ability to control the business and affairs
of the Company.

RECENT DEVELOPMENTS

     In February 1999, the Company sold its Anadarko, Oklahoma branch, which had
deposits of approximately $15.5 million, to a local financial institution.  The
sale resulted in a pretax gain of approximately $900,000.

SUPERVISION AND REGULATION

BANK HOLDING COMPANY REGULATION

     The following discussion sets forth certain of the material elements of the
regulatory framework applicable to bank holding companies and their subsidiaries
and provides certain specific information relevant to the Company. This
regulatory framework is intended primarily for the protection of depositors and
not for the protection of the Company's stockholders.  To the extent that the
following information describes statutory and regulatory provisions, it is
qualified in its entirety by reference to those provisions.  A change in the
statutes, regulations or regulatory policies applicable to the Company or its
subsidiaries may have a material effect on the business of the Company.

GENERAL

     As a bank holding company, the Company is subject to regulation and
examination by the Federal Reserve Board under the Bank Holding Company Act of
1956, as amended ("BHCA").  BancFirst is organized as a state-chartered banking
association which is subject to regulation, supervision and examination by the
Oklahoma State Banking Department (the "Banking Department").  BancFirst is also
subject to regulation by the Federal Deposit Insurance Company (the "FDIC") and
other federal and state regulatory agencies.  In addition to banking laws,
regulations and regulatory agencies, the Company and its subsidiaries and
affiliates are subject to various other laws and regulations and supervision and
examination by other regulatory agencies, all of which directly or indirectly
affect the operations and management of the Company and its ability to make
distributions. The following discussion summarizes certain aspects of those laws
and regulations that affect the Company.

     The BHCA requires the prior approval of the Reserve Board in any case where
a bank holding company proposes to acquire control of more than five percent of
the voting shares of any bank, unless it already controls a majority of such
voting shares. Additionally, approval must also be obtained before a bank
holding company may acquire all or substantially all of the assets of another
bank or before it may merge or consolidate with another bank holding company.
The BHCA further provides that the Reserve Board shall not approve any such
acquisition, merger or consolidation that will substantially lessen competition,
tend to create a monopoly or be in restraint of trade, unless it finds the anti-
competitive effects of the proposed transaction are clearly outweighed in the
public interest by the probable effect of the transaction in meeting the
convenience and needs of the community to be served.

     In addition, and subject to certain exceptions, the Change in Bank Control
Act (the "Control Act") and regulations promulgated thereunder by the Federal
Reserve Board require any person acting directly or indirectly, or through or in
concert with one or more persons, to give the Federal Reserve 60 days' written
notice before acquiring control of a bank holding company. Transactions which
are presumed to constitute the acquisition of control include the acquisition of
any voting securities of a bank holding company having securities registered
under section 12 of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), if, after the transaction, the acquiring person (or persons
acting in concert) owns, controls or holds with power to vote 25% or more of any
class of voting securities of the institution. The acquisition may not be
consummated subsequent to such notice if the Federal Reserve Board issues a
notice within 60 days, or within certain extensions of such period, disapproving
the same.

     Pursuant to the Riegle-Neal Interstate Banking and Branching Efficiency Act
of 1994 (the "Interstate Banking and Branching Act"), a bank holding company may
acquire banks in states other than its home state without regard to the
permissibility of such acquisitions under state law, but subject to any state
requirement that the bank has been organized and operating for a minimum period
of time, not to exceed five years, and the requirement that the bank holding
company, prior to or following the proposed acquisition, controls no more than
10 percent of the total amount of deposits of insured depository institutions in
the United States and no more than 30 percent of such deposits in that state (or
such lesser or greater amount set by state law).

     Subject to certain restrictions, the Interstate Banking and Branching Act
also authorizes banks to merge across state lines, thereby creating interstate
branches. Furthermore, pursuant to the Interstate Banking and Branching Act, a
bank may open new branches in a state in which it does not already have banking
operations if such state enacts a law permitting such de novo branching. See
"State Regulation-Branch and Interstate Banking."

                                       5
<PAGE>
 
     The BHCA also prohibits a bank holding company, with certain exceptions,
from acquiring more than five percent of the voting shares of any company that
is not a bank and from engaging in any business other than banking or managing
or controlling banks. Under the BHCA, the Federal Reserve Board is authorized to
approve the ownership of shares by a bank holding company in any company whose
activities the Reserve Board has determined to be so closely related to banking
or to managing or controlling banks as to be a proper incident thereto. In
making such determinations, the Federal Reserve Board weighs the Community
Reinvestment Act activities of the bank holding company and the expected benefit
to the public, such as greater convenience, increased competition or gains in
efficiency, against the possible adverse effects, such as undue concentration of
resources, decreased or unfair competition, conflicts of interest or unsound
banking practices. The Federal Reserve Board has by regulation determined that
certain activities are closely related to banking within the meaning of the
BHCA. These activities include operating a mortgage company, finance company,
credit card company or factoring company; performing certain data processing
operations; servicing loans and other extensions of credit; providing investment
and financial advice; acting as an insurance agent for certain types of credit-
related insurance; owning and operating savings and loan associations; and
leasing personal property on a full pay-out, nonoperating basis.

     A bank holding company and its subsidiaries are further prohibited under
the BHCA from engaging in certain tie-in arrangements in connection with the
provision of any credit, property or services. Thus, a subsidiary of a bank
holding company may not extend credit, lease or sell property, furnish any
services or fix or vary the consideration for these activities on the condition
that (1) the customer obtain or provide some additional credit, property or
services from or to the bank holding company or any subsidiary thereof or (2)
the customer may not obtain some other credit, property or services from a
competitor, except to the extent reasonable conditions are imposed to insure the
soundness of credit extended.

     The Federal Reserve Board has issued regulations under the BHCA that
require a bank holding company to serve as a source of financial and managerial
strength to its subsidiary banks. Pursuant to such regulations, the Federal
Reserve Board may require the Company to stand ready to use its resources to
provide adequate capital funds to its banking subsidiaries during periods of
financial stress or adversity. Under the Federal Deposit Insurance Company
Improvement Act of 1991 ("FDICIA"), a bank holding company is required to
guarantee the compliance of any insured depository institution subsidiary that
may become "undercapitalized" (as defined in the statute) with the terms of any
capital restoration plan filed by such subsidiary with its appropriate federal
banking agency, up to specified limits. See "FDICIA and Related Regulations,"
below. Under the BHCA, the Federal Reserve Board has the authority to require a
bank holding company to terminate any activity or relinquish control of a
nonbank subsidiary (other than a nonbank subsidiary of a bank) upon the Federal
Reserve Board's determination that such activity or control constitutes a
serious risk to the financial soundness and stability of any bank subsidiary of
the bank holding company.

CAPITAL ADEQUACY GUIDELINES

     The Federal Reserve Board, the Comptroller and the FDIC have issued
substantially similar risk-based and leverage capital guidelines applicable to
United States banking organizations.  In addition, these regulatory agencies may
from time to time require that a banking organization maintain capital above the
minimum levels, whether because of its financial condition or actual or
anticipated growth.  The Federal Reserve Board risk-based guidelines define a
three-tier capital framework.  Tier 1 capital consists of common and qualifying
preferred stockholders' equity, less certain intangibles and other adjustments.
Tier 2 capital consists of preferred stock not qualifying as Tier 1 capital,
subordinated and other qualifying debt, and the allowance for credit losses up
to 1.25 percent of risk-weighted assets.  Tier 3 capital includes subordinated
debt that is unsecured, fully paid, has an original maturity of at least two
years, is not redeemable before maturity without prior approval by the Federal
Reserve and includes a lock-in clause precluding payment of either interest or
principal if the payment would cause the issuing bank's risk-based capital ratio
to fall or remain below the required minimum.  The sum of Tier 1 and Tier 2
capital less investments in unconsolidated subsidiaries represents qualifying
total capital, at least 50 percent of which must consist of Tier 1 capital.
Risk-based capital ratios are calculated by dividing Tier 1 and total capital by
risk-weighted assets.  Assets and off-balance sheet exposures are assigned to
one of four categories of risk-weights, based primarily on relative credit risk.
The minimum Tier 1 capital ratio is 4 percent and the minimum total capital
ratio is 8 percent.  The Company's Tier 1 and total risk-based capital ratios
under these guidelines at December 31, 1998 were 14.31% and 15.57%,
respectively.  At December 31, 1998, the Company had no subordinated debt that
qualified as Tier 3 capital.

     The Federal Reserve Board also requires bank holding companies to maintain
a minimum "leverage ratio" (Tier 1 capital to adjusted total assets) of 3%.
These ratio requirements are minimums. Any institution operating at or near
those levels would be expected by the regulators to have well-diversified risk,
including no undue interest rate risk exposures, excellent asset quality, high
liquidity, and good earnings and, in general, would have to be considered a
strong banking organization. All other organizations and any institutions
experiencing or anticipating significant growth are expected to maintain capital
ratios at least one to two percent above the minimum levels, and higher capital
ratios can be required if warranted by particular circumstances or risk profile.
For information regarding the Company's recent historical capital ratios, see
"Financial Review - Capital Resources".

IMPROVEMENT ACT AND RELATED REGULATIONS

     General. FDICIA, among other things, identifies five capital categories for
insured depository institutions (well capitalized, adequately capitalized,
undercapitalized, significantly undercapitalized and critically
undercapitalized) and requires the respective Federal regulatory agencies to
implement systems for "prompt corrective action" for insured depository
institutions that do not meet minimum capital requirements within such
categories. FDICIA imposes progressively more restrictive constraints on
operations, management and capital distributions, depending on the category in
which an institution is classified. Failure to meet the capital guidelines could
also subject a banking institution to capital raising requirements. An
"undercapitalized" bank must develop a capital restoration plan and its parent
holding company must guarantee that bank's compliance with the plan. The
liability of the parent holding company under any such guarantee is limited to
the lesser of 5 percent of the bank's assets at the time it became
"undercapitalized" or the amount needed to comply with the plan. Furthermore, in
the event of the bankruptcy of the parent holding company, such guarantee would
take priority over the parent's general unsecured creditors. In addition, FDICIA
requires the various regulatory agencies to prescribe certain non-capital
standards for safety and soundness relating generally to operations and
management, asset quality and executive compensation and permits regulatory
action against a financial institution that does not meet such standards.

     The various regulatory agencies have adopted substantially similar
regulations that define the five capital categories (well capitalized,
adequately capitalized, undercapitalized, significantly undercapitalized and
critically undercapitalized) identified by FDICIA, using the total risk-based
capital, Tier 1 risk-based capital and leverage capital ratios as the relevant
capital measures, and requires the respective Federal regulatory agencies to
implement systems for "prompt corrective action" for insured depository
institutions that do not meet minimum capital requirements within such
categories. Such regulations establish various degrees of corrective action to
be taken when an institution is considered undercapitalized.

     Significantly or critically undercapitalized institutions and
undercapitalized institutions that do not submit and comply with capital
restoration plans acceptable to the applicable Federal banking regulator are
subject to one or more of the following sanctions: (i) forced sale of shares to
raise capital, or, where grounds exist for the appointment of a receiver or
conservator, a forced merger; (ii) restrictions on transactions with affiliates;
(iii) limitations on interest rates paid on deposits; (iv) further restrictions
on growth or required shrinkage; (v) replacement of directors or senior
executive directors; (vi) prohibitions on the receipt of correspondent deposits;
(vii) restrictions on capital distributions by the holding companies of such
institutions; (viii) required divestiture of subsidiaries by the institution; or
(ix) other restrictions, as determined by the regulator. In addition, the
compensation of executive officers will be frozen at the level in effect when
the institution failed to meet the capital standards and may be increased only
with the applicable Federal banking regulator's prior written approval. The
applicable Federal banking regulator is required to impose a forced sale of
shares or merger, restrictions on affiliate transactions and restrictions on
rates paid on deposits unless it determines that such actions would not further
an institution's capital improvement. In addition to the foregoing, a critically
undercapitalized institution would be prohibited from making any payment of
principal or interest on subordinated debt without the concurrence of its
regulator and the FDIC, beginning 60 days after the institution becomes
critically undercapitalized. A critically undercapitalized institution may not,
without FDIC approval: (i) enter into material transactions outside of the
ordinary course of business; (ii) extend credit on highly leveraged
transactions; (iii) amend its charter or bylaws; (iv) make any material change
in its accounting methods; (v) engage in any covered transactions with
affiliates; (vi) pay excessive compensation or bonus (as defined); or (vii) pay
rates on liabilities significantly in excess of market rates.

     Under the regulations, a "well capitalized" institution must have a Tier 1
capital ratio of at least 6 percent, a total capital ratio of at least 10
percent and a leverage ratio of at least 5 percent and not be subject to a
capital directive order. Under these guidelines, BancFirst is considered well
capitalized.

     Banking agencies have also adopted final regulations which mandate that
regulators take into consideration (i) concentrations of credit risk; (ii)
interest rate risk (when the interest rate sensitivity of an institution's
assets does not match the sensitivity of its liabilities or its off-balance-
sheet position); and (iii) risks from non-traditional activities, as well as an
institution's ability to manage those risks, when determining the adequacy of an
institution's capital. That evaluation will be made as a part of the
institution's regular safety and soundness examination. In addition, the banking
agencies have amended their regulatory capital guidelines to incorporate a
measure for market risk. The revised guidelines did not have a material impact
on the Company or BancFirst's regulatory capital ratios or their well
capitalized status.

REGULATORY RESTRICTIONS ON DIVIDENDS

     BancFirst, as a member bank of the Federal Reserve System, may not declare
a dividend without the approval of the Federal Reserve Board unless the dividend
to be declared by BancFirst does not exceed the total of (i) BancFirst's net
profits (as defined and interpreted by regulation) for the current year to date
plus (ii) its retained net profits (as defined and interpreted by regulation)
for the preceding two years, less any required transfers to surplus. In
addition, BancFirst can only pay dividends to the extent that its retained net
profits (including the portion transferred to surplus) exceed its bad debts (as
defined by regulation). Under the Federal Deposit Insurance Act, no dividends
                                       7
<PAGE>
 
may be paid by an insured bank if the bank is in arrears in the payment of any
insurance assessment due to the FDIC. Under these provisions BancFirst may
declare during 1999, without prior regulatory approval, aggregate dividends of
$12 million, plus net profits earned to the date of such dividend declaration in
1999. State and federal regulatory authorities have adopted standards for the
maintenance of adequate levels of capital by banks. See "Capital Adequacy
Guidelines," above. Adherence to such standards further limits the ability of
banks to pay dividends. The payment of dividends by any subsidiary bank may also
be affected by other regulatory requirements and policies, such as the
maintenance of adequate capital. If, in the opinion of the applicable regulatory
authority, a bank under its jurisdiction is engaged in, or is about to engage
in, an unsafe or unsound practice (which, depending on the financial condition
of the bank, could include the payment of dividends), such authority may
require, after notice and hearing, that such bank cease and desist from such
practice. The Federal Reserve Board has formal and informal policies which
provide that insured banks and bank holding companies should generally pay
dividends only out of current operating earnings.

DEPOSIT INSURANCE

     BancFirst is insured by the FDIC and is required to pay certain fees and
premiums to the Bank Insurance Fund ("BIF").  These deposit insurance premiums
are assessed through a risk-based system under which all insured depository
institutions are placed into one of nine categories and assessed insurance
premiums on deposits based upon their level of capital and supervisory
evaluation, with the well-capitalized banks with the highest supervisory rating
paying a premium of 0.00% of deposits and the critically undercapitalized banks
paying up to 0.27% of deposits.  In addition, the Deposit Insurance Fund Act of
1996 implemented an additional assessment on BIF deposits and deposits insured
by the Savings Association Insurance Fund ("SAIF") administered by the FDIC, in
order to service the interest on the Financing Corporation ("FICO") bond
obligations which were used to finance the cost of "thrift bailouts" in the
1980's.  The FICO assessments do not vary depending upon a depository
institution's capitalization or supervisory evaluations.  The FICO assessment
rates for the first semi-annual period of 1999 were set at $.0122 per $100 of
insured deposits for BIF assessable deposits and $.061 per $100 in deposits for
SAIF assessable deposits.  These rates may be adjusted quarterly to reflect
changes in assessment basis for the BIF and SAIF.  By law, the FICO rate on BIF
assessable deposits must be one-fifth of the rate on SAIF assessable deposits
until the insurance funds are merged or until January 1, 2000, whichever occurs
first.

DEPOSITOR PREFERENCE STATUTE

     Federal legislation has been enacted providing that deposits and certain
claims for administrative expenses and employee compensation against an insured
depository institution would be afforded a priority over other general unsecured
claims against such institution, including federal funds and letters of credit,
in the "liquidation or other resolution" of the institution by any receiver.

STATE REGULATION

     General.  BancFirst is an Oklahoma-chartered state bank.  Accordingly,
BancFirst's operations are subject to various requirements and restrictions of
state law relating to loans, lending limits, interest rates payable on deposits,
investments, mergers and acquisitions, borrowings, dividends, capital adequacy,
and other matters.  Because BancFirst is a member of the Federal Reserve System,
Oklahoma law provides that BancFirst must maintain reserves against deposits as
required by the Federal Reserve Act.  BancFirst is subject to primary
supervision, periodic examination and regulation by the Oklahoma State Banking
Department and the Federal Reserve Board. The Oklahoma State Bank Commissioner
is authorized by statute to accept a Federal Reserve System examination in lieu
of a state examination.  In practice, the Federal Reserve Board and the Oklahoma
State Banking Department alternate examinations of BancFirst.  If, as a result
of an examination of a bank, the Oklahoma State Banking Department determines
that the financial condition, capital resources, asset quality, earnings
prospects, management, liquidity, or other aspects of the bank's operations are
unsatisfactory or that the management of the bank is violating or has violated
any law or regulation, various remedies, including the remedy of injunction, are
available to the Oklahoma State Banking Department.  Oklahoma also permits the
acquisition of an unlimited number of wholly-owned bank subsidiaries so long as
aggregate deposits at the time of acquisition in a multi-bank holding company do
not exceed 15% of all deposits in Oklahoma financial institutions insured by the
federal government, exclusive of credit union deposits.

     State Bank Holding Company Regulation.  The BHC allows the Federal Reserve
Board 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 bank located in a state other than such
holding company's home state, without regard to whether the transaction is
prohibited by the laws of any state.  The Federal Reserve Board may not approve
the acquisition of a bank that has not been in existence for the minimum time
period (not exceeding five years), if any, specified by the statutory law of the
host state.  The BHC also prohibits the Federal Reserve Board 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 bank's home state or in any
state in which the target bank maintains a branch.  The BHC 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 bank or bank holding company to the
extent such limitation does not discriminate against out-of-state banks or bank
holding

                                       8
<PAGE>
 
companies. Individual states may also waive the 30% state-wide concentration
limit.

  Under Oklahoma law, any bank holding company or other company which submits an
application to the Federal Reserve Board for approval of the acquisition of a
state or national bank located in Oklahoma must submit a copy of such
application to the Oklahoma Bank Board.  Subject to certain exceptions for
supervisory acquisitions and certain other limited exceptions, Oklahoma law
further provides that it shall be unlawful for a multi-bank holding company to
acquire direct or indirect ownership or control of any financial institution
with deposits insured by the FDIC or the National Credit Union Administration
("NCUA") and located in Oklahoma if such acquisition results in such multi-bank
holding company having direct or indirect ownership or control of banks located
in Oklahoma, the total deposits of which at the time of such acquisition exceed
15% of aggregate deposits of all financial institutions with deposits insured by
the FDIC and the NCUA.  See "-Branch and Interstate Banking."

  Branch and Interstate Banking.  Currently, Oklahoma law provides that Oklahoma
banks may establish no more than two branches within the corporate city limits
where the main bank is located or within 25 miles of the main bank if it is
located in a city that has no other bank.  Oklahoma banks, however, may acquire
an unlimited number of offices of other banks or savings associations provided
that the bank does not control more than 15% of the insured deposits in the
State of Oklahoma.   Recently, Oklahoma law had been interpreted to permit more
extensive branching, through the use of so-called "phantom," or interim, bank
charters.  In late 1998, BancFirst received permission to establish an
additional branch under this interpretation to support its existing operations
in the Oklahoma City metropolitan market.  Other Oklahoma banks also applied
for, and received permission to establish, branches under this interpretation.
However, the Oklahoma State Banking Board's decision approving one such interim
charter became the subject of a legal challenge, and on March 30, 1999, the
Oklahoma Supreme Court reversed the order of the Banking Board with respect to
the charter in question.  Although no parties have appeared within the requisite
time period provided by the court to oppose BancFirst's interim charter, the
effect of the Oklahoma Supreme Court decision will be the curtailment of
branching by such method.

  Beginning on June 1, 1997, pursuant to the Interstate Banking and Branching
Act, the federal banking agencies were authorized to approve interstate bank (as
opposed to bank holding company) merger transactions without regard to whether
such transactions are prohibited by the law of any state, unless the home state
of one of the banks had "opted out" of interstate branching by enacting specific
legislation prior to June 1, 1997, in which case out-of-state banks would
generally not be able to branch into that state, and banks headquartered in that
state would not be permitted to branch into other states.  Oklahoma elected to
"opt-in" to interstate branching effective May 1997 and established a 12.25%
deposit cap which was subsequently increased to 15%.

  Federal law also generally allows bank holding companies to acquire or
establish federal savings associations, without regard to location.  Under
federal law, federal savings associations may establish or acquire branches in
or outside of their home states without regard to state restrictions.

  Furthermore, pursuant to the Interstate Banking and Branching Act, a bank may
open new branches in a state in which it does not already have banking
operations if such state enacts a law permitting such de novo branching.
Currently, Oklahoma law does not.  However, Section 381.24a(B) of the Oklahoma
Savings and Loan Code of 1970 provides that, after July 1, 1999, new savings and
loan association branches may be established with permission granted by order of
the Oklahoma State Banking Commissioner without regard to the restrictions
otherwise provided in such subsection, which are substantially identical to the
two de novo branch limitation contained in the Oklahoma Banking Code.
Accordingly, after such date, and absent further legislation, national banks
would have the ability to establish de novo branches on an unlimited, state-wide
basis (subject to the deposit cap), although state-chartered banks would still
be subject to the branching limits contained in the Oklahoma Banking Code.  In
an effort to ensure parity between national and state-chartered banks, the
Oklahoma legislature on March 24, 1999 amended Section 402(12) of the Oklahoma
Banking Code to provide that state-chartered banks would be entitled to the same
rights and privileges as those extended to national banks.  The effective date
of the amendment is July 1, 1999, after which time BancFirst will be able to
establish an unlimited number of de novo branches in Oklahoma (assuming no
successful legal challenge to the amendment).

GOVERNMENTAL MONETARY AND FISCAL POLICIES

  The commercial banking business is affected directly by the monetary policies
of the Federal Reserve Board and by the fiscal policies of federal, state and
local governments.  The Federal Reserve Board, in fulfilling its role of
stabilizing the nation's money supply, utilizes several operating tools, all of
which directly impact commercial bank operations.  The primary tools used by the
Federal Reserve Board are changes in reserve requirements on member bank
deposits and other borrowings, open market operations in the U.S. Government
securities market, and control over the availability and cost of members' direct
borrowings from the "discount window."  Banks act as financial intermediaries in
the debt capital markets and are active participants in these markets daily.  As
a result, changes in governmental monetary and fiscal policies have a direct
impact upon the level of loans and investments, the availability of sources of
lendable funds, and the interest rates earned from and paid on these
instruments.  It is not possible to predict accurately the future course of such
government policies and 

                                       9
<PAGE>
 
the residual impact upon the operations of the Company.

PENDING AND PROPOSED LEGISLATION

     There are various pending and proposed bills in Congress that, among other
things, could restructure the federal supervision of financial institutions.
The Company is unable to predict with any certainty the effect any such
legislation would have on the Company, its subsidiaries or their respective
activities.  Additional legislation, judicial and administrative decisions also
may affect the ability of banks to compete with each other as well as with other
businesses.  These statutes and decisions may tend to make the operations of
various financial institutions more similar and increase competition among banks
and other financial institutions or limit the ability of banks to compete with
other businesses.  Management currently cannot predict whether and, if so, when
any such changes might occur or the impact any such changes would have upon the
income or operations of the Company or its subsidiaries, or upon the Oklahoma
regional banking environment.

ITEM 2.  PROPERTIES.

     The principal offices of the Company are located at 101 North Broadway,
Suite 200, Oklahoma City, Oklahoma 73102.  The Company owns substantially all of
the properties and buildings in which its various offices and facilities are
located.  These properties include 57 full service branches and 14 limited
service detached facilities.  BancFirst also owns properties for future
expansion.  There are no significant encumbrances on any of these properties.

ITEM 3.  LEGAL PROCEEDINGS.

     The Company has been named as a defendant in various legal actions arising
from the conduct of its normal business activities.  Although the amount of any
liability that could arise with respect to these actions cannot be accurately
predicted, in the opinion of the Company, any such liability will not have a
material adverse effect on the consolidated financial position of the Company.

ITEM 4.  SUBMISSION OF MATTERS TO VOTE OF SECURITY HOLDERS.

     There were no matters submitted to a vote of security holders, through the
solicitation of proxies or otherwise, during the fourth quarter of the year
ended December 31, 1998.

     As of March 31, 1999 there were approximately 550 holders of record of the
Common Stock.

     Future dividend payments will be determined by the Company's Board of
Directors in light of the earnings and financial condition of the Company and
the Bank, their capital needs, applicable governmental policies and regulations
and such other factors as the Board of Directors deems appropriate.

     BancFirst Corporation is a legal entity separate and distinct from the
Bank, and its ability to pay dividends is substantially dependent upon dividend
payments received from the Bank.  Various laws, regulations and regulatory
policies limit the Bank's ability to pay dividends to BancFirst Corporation, as
well as BancFirst Corporation's ability to pay dividends to its shareholders.

                               FINANCIAL REVIEW

     The following discussion is an analysis of the financial condition and
results of operations of the Company for the three years ended December 31, 1998
and should be read in conjunction with the Consolidated Financial Statements and
Notes thereto and the Selected Consolidated Financial Data included herein.

SUMMARY

     BancFirst Corporation posted its eighth consecutive year of record earnings
for 1998.  At the same time, the Company grew over 73% by adding $990 million in
assets through acquisitions and internal growth.  Four acquisitions were
completed during the year, two of which were accounted for as poolings of
interests.  Acquisition and restructuring costs of over $3.1 million were
absorbed in current year earnings as a result of these transactions.

     Net income for 1998 was $21.6 million, up from $20.9 million for 1997 and
$21.2 million for 1996, on a restated basis for the pooling of interests
transactions.  The corresponding diluted earnings per share figures were $2.27
for 1998, $2.21 for 1997 and $2.22 for 1996.

     Total assets increased to $2.34 billion, from $2.02 billion on a restated
basis.  Total loans increased $89 million, or 7.12%.  Total deposits increased
$263 million, or 14.9%.  Stockholders' equity rose $20.7 million to $202
million, an 11.4% increase.  Average stockholders' equity to average assets
increased to 9.09%, from 8.95% for 1997.

     Asset quality remained high in 1998 with nonperforming and restructured
assets to total assets of only 0.60%, compared to 0.51% for 1997.  The allowance
for possible loan losses to nonperforming and restructured loans was 158.69% at
year-end 1998 and 206.55% at the end of 1997.

     In March 1998, the Company completed its purchase of 13 branches from
NationsBank, N.A. and concurrently sold three of the branches to another
Oklahoma financial institution.  An additional four branches were subsequently
sold to other local financial institutions.  These transactions resulted in the
acquisition of $30 million in net loans and other assets, and the assumption of
$78 million in net deposits.

     In May 1998, the Company completed a merger with Lawton Security
Bancshares, Inc. ("Lawton Security Bancshares"), which had approximately $92
million in total assets. Lawton Security Bancshares' principal subsidiary was
Security Bank & Trust Company of Lawton, Oklahoma, which was merged into
BancFirst. The merger was effected through an exchange of stock and was
accounted for as a pooling of interests.

     In October 1998, the Company completed a merger with AmQuest Financial
Corp. ("AmQuest"), which had approximately $526 million in total assets.
AmQuest's principal subsidiaries were AmQuest Bank, N.A. and Exchange National
Bank & Trust Company, which operated in six communities in south-central
Oklahoma, and which were merged into BancFirst. Restructuring charges of $1.9
million were incurred, consisting of termination benefits of $345,000 and losses
on facilities other assets to be sold or abandoned, of $1.57 million. The merger
was effected through an exchange of stock and was accounted for as a pooling of
interests.

     In December 1998, the Company completed an acquisition of Kingfisher
Bancorp, Inc. ("Kingfisher Bancorp"), which had approximately $91 million in
total assets.  Kingfisher Bancorp's principal subsidiary was Kingfisher Bank &
Trust Co. of Kingfisher, Oklahoma, which was merged into BancFirst in March
1999.  The acquisition was for cash of $12 million and was accounted for as a
purchase.

RESULTS OF OPERATIONS

NET INTEREST INCOME

     Net interest income, which is the Company's principal source of operating
revenue, increased 10.1% in 1998 to $92.8 million, after an increase of 8.02% in
1997.  The net interest margin on a taxable equivalent basis for 1998 was 4.83%,
down from 4.93% for 1997 and 5.05% for 1996.  Changes in the volume of earning
assets and interest-bearing liabilities, and changes in interest rates determine
the change in net interest income.  The Volume/Rate Analysis summarizes the
relative contribution of each of these components to the increases in net
interest income in 1998 and 1997.  The increase in net interest income in 1998
was due to growth in loans and net earning assets.  Average loans rose 9.24%.
At the same time, average net earning assets increased to $396 million from $332
million for 1997.  In 1997, average loans increased 12.76% and average net
earning assets increased to $332 million from $301 million for 1996.  The
declining net interest margin is the result of several factors including low
interest rates, a flatter yield curve and loan pricing competition.  This is
reflected in the negative rate variances for 1998 and 1997.

</TABLE>

     Interest rate sensitivity analysis measures the sensitivity of the
Company's net interest margin to changes in interest rates by analyzing the
repricing relationship between its earning assets and interest-bearing
liabilities.  This analysis is limited by the fact that it presents a static
position as of a single day and is not necessarily indicative of the Company's
position at any other point in time, and does not take into account the
sensitivity of yields and rates of specific assets and liabilities to changes in
market rates.  In 1998, Management continued its strategy of creating manageable
negative interest sensitivity gaps.  This approach takes advantage of the
Company's stable core deposit base and the relatively short maturity and
repricing frequency of its loan portfolio, as well as the historical existence
of a positive yield curve, which enhances the net interest margin over the long
term.  Although interest rate risk is increased on a controlled basis by this
position, it is somewhat mitigated by the Company's high level of liquidity.

     The Analysis of Interest Rate Sensitivity presents the Company's earning
assets and interest-bearing liabilities based on maturity and repricing
frequency at December 31, 1998.  At that date, interest-bearing liabilities
exceeded earning assets by $492 million in the three month interval. The
Company's negative gap position increased in 1998 and 1997 as a result of the
majority of its earning asset growth having a maturity or repricing frequency of
one to five years.  This negative gap position assumes that the Company's core
savings and transaction deposits are immediately rate sensitive and reflects
Management's perception that the yield curve will be positively sloped over the
long term.  When the yield curve flattens, as it did in 1997 and 1998, the
Company's net interest margin would be expected to decline, unless the Company
adjusts its interest sensitivity gap position or employs other strategies to
control the rise in rates on interest-bearing liabilities or to increase the
yield on earning assets.

PROVISION FOR POSSIBLE LOAN LOSSES

     The provision for possible loan losses was $2.21 million for 1998 compared
to $2.89 million for 1997, and $2.18 million for 1996.  These relatively low
levels of provisions reflect the Company's strong asset quality.  The amounts
provided for the last three years primarily relate to loan growth and net loan
charge-offs.  The Company establishes a 1% allowance for possible losses on non-
classified loans.  Net loan charge-offs were $1.85 million for 1998, compared to
$2.31 million for 1997 and $1.39 million for 1996.  The net charge-offs for 1998
and 1997 were equivalent to only 0.14% and 0.20% of average loans, respectively.
A more detailed discussion of the allowance for possible loan losses is provided
under "Loans."

NONINTEREST INCOME

     Noninterest income increased in 1998 by $2.51 million, or 11.67%, compared
to an increase of $1.51 million, or 7.53% in 1997 and $2.6 million, or 14.95%,
in 1996.  Noninterest income has become an increasingly important source of
revenue.  The Company's fee income has increased each year since 1987 due to
improved pricing strategies, enhanced product lines and bank acquisitions.  New
products and strategies have been implemented which are expected to produce
continued growth in noninterest income.

     Service charges on deposits increased $1.48 million, or 11.24%, compared to
increases of 12.3% and 10.9% in 1997 and 1996, respectively.  In 1997 and 1998,
the Company implemented strategies to improve the charging and collection of
various service charges.  The growth in 1996 was primarily due to acquisitions.
Other noninterest income decreased $1.02 million, or 12.24%, in 1998, after
increasing 3.46% in 1997 and 20.41% in 1996.  The primary causes of the
increases were increased fees from mortgage loan originations, gains on sales of
mortgage loans and higher trust revenues.

     Net gains on securities transactions were only $12,000 in 1998, compared to
$2,000 in 1997, and $219,000 in 1996.  The Company's practice is to hold its
securities to maturity and it does not engage in trading activities.  The small
gains from securities transactions have 

                                      A-6
<PAGE>
 
primarily been from securities that have been called or from disposing of
securities acquired in mergers which had a higher than acceptable level of risk.
A more detailed discussion of securities is provided under "Securities."

NONINTEREST EXPENSE

     Total noninterest expense increased in 1998 by 12.6% to $80.5 million,
compared to increases of 14.5% for 1997 and 15.7% for 1996.  Noninterest expense
in 1998 included $3.1 million of acquisition and restructuring costs.  The
increase in 1998, before these acquisition and restructuring costs was 8.15 %.
Salaries and employee benefits have increased over the past three years due to
acquisitions, higher salary levels, additional staff for new product lines and
increased loan demand.  Occupancy and fixed asset expense, depreciation,
amortization and data processing services all increased due to acquisitions.
Net income from other real estate owned of $111,000 was recognized for 1998,
compared to net expense of $298,000 and $57,000 for 1997 and 1996.  These
amounts are reflective of the Company's efforts to reduce nonperforming assets,
with gains on sales of properties being recognized in 1998.

INCOME TAXES

     Income tax expense increased to $12.5 million in 1998, from $10.5 million
for 1997 and $12.2 million for 1996.  The primary reasons for the difference
between the Company's effective tax rate and the federal statutory rate are
nondeductible amortization and state tax expense.  In 1997, the Company
recognized a benefit of $193,000 for a state net operating loss carryforward.
The Company also utilized substantial amounts of net operating loss
carryforwards in 1993 and 1994.  The remaining carryforwards are limited as to
the amounts which may be utilized each year.

     Since banks have traditionally carried large amounts of tax-exempt
securities and loans, certain financial information is prepared on a taxable
equivalent basis to facilitate analysis of yields and changes in components of
earnings.  Average balance sheets, income statements and other financial
statistics on a taxable equivalent basis have been presented for this purpose.

IMPACT OF INFLATION

     The impact of inflation on financial institutions differs significantly
from that of industrial or commercial companies.  The assets of financial
institutions are predominantly monetary, as opposed to fixed or nonmonetary
assets such as premises, equipment and inventory.  As a result, there is little
exposure to inflated earnings by understated depreciation charges or
significantly understated current values of assets.  Although inflation can have
an indirect effect by leading to higher interest rates, financial institutions
are in a position to monitor the effects on interest costs and yields and
respond to inflationary trends through management of interest rate sensitivity.
Inflation can also have an impact on noninterest expenses such as salaries and
employee benefits, occupancy, services and other costs.


FINANCIAL POSITION

CASH AND FEDERAL FUNDS SOLD

     Cash consists of cash and cash items on hand, deposits and other amounts
due from other banks, and reserves deposited with the Federal Reserve Bank.
Federal funds sold consists of overnight investments of excess funds with other
financial institutions.  The amount of cash and federal funds sold carried by
the Company is a function of the availability of funds presented to other
institutions for clearing, the Company's requirements for liquidity, operating
cash and reserves, available yields, and interest rate sensitivity management.
Balances of these items can fluctuate widely based on these various factors.
Cash and federal funds sold increased $155 million compared to December 31,
1997, due largely to an inflow of temporary deposits at year-end 1998 and the
Company's increased level of federal funds purchased from correspendent banks.
In 1997, cash and federal funds sold  decreased $13.8 million as compared to
year-end 1996.  Based on average balances, however, there were increases of
$48.1 million and $21.3 million for 1998 and 1997, respectively.  Consequently,
comparisons of year-end balances of cash and federal funds sold are not
necessarily reflective of the overall trend.

SECURITIES

     During 1998, total securities increased $72.2 million, or 14.1%, compared
to an increase of $33.2 million, or 6.96%, in 1997.  The increase in 1998 was
primarily due to acquisitions, while the increase in 1997 was in line with the
internal growth of the Company.

     Securities available for sale represented 77.6% of the total securities
portfolio at year-end 1998, compared to 69.8% at year-end 1997. These levels
reflect the Company's strategy of maintaining a very liquid portfolio.
Securities available for sale had a net unrealized gain of $8.25 million at
year-end 1998, compared to $2.78 million the preceding year.  These gains are
included, net of tax, in the Company's stockholders' equity as $5.43 million and
$1.79 million, respectively.

     The Maturity Distribution of Securities summarizes the maturity and
weighted average taxable equivalent yields of the securities portfolio.  The
Company manages its securities portfolio for liquidity and as a tool to execute
its asset/liability management strategy.  Consequently, the average maturity of
the portfolio is relatively short.  Securities maturing within five years
represents 91.3% of the total portfolio.

LOANS

     The Company has generated significant loan growth over the past nine years
from both acquisitions and internal originations.  Total loans increased $89.2
million, or 7.14%, in 1998, and $124 million, or 11.1%, in 1997.  Internal
growth is being generated primarily in the Oklahoma City and Tulsa metropolitan
markets, and by specialized lending activities such as guaranteed student loans,
SBA guaranteed loans and residential mortgage loans.

Composition

     The Company's loan portfolio is diversified among various types of
commercial and individual borrowers.  Commercial loans are comprised principally
of loans to companies in light manufacturing, retail and service industries.
Construction and development loans totaled only $75.9 million, or 5.67% of total
loans as of the end of 1998.  Real estate loans are relatively evenly divided
between mortgages on personal residences and loans secured by commercial and
other types of properties.  Installment loans are comprised mostly of loans to
individuals for the purchase of vehicles and student loans.  Loans secured by
real estate have always been a large proportion of the Company's loan portfolio.
In 1998, this percentage was 55.2% compared to 53.3% for 1997.  The Company is
subject to risk of future market fluctuations in property values relating to
these loans.  The Company attempts to manage this risk through rigorous loan
underwriting standards, training of loan officers and close monitoring of the
values of individual properties.

     The majority of the commercial real estate and other commercial loans have
maturities of one year or less. However, many of these loans are renewed at
existing or similar terms after scheduled principal reductions. Also, over half
of the commercial real estate and other commercial loans had adjustable interest
rates at year-end 1998. The short maturities and adjustable interest rates on
these loans allow the Company to maintain the majority of its loan portfolio
near market interest rates.

     The information relating to the maturity and rate sensitivity of loans is
based upon original loan terms and is not adjusted for "rollovers."  In the
ordinary course of business, loans maturing within one year may be renewed, in
whole or in part, at interest rates prevailing at the date of renewal.

Nonperforming and Restructured Loans

     Nonperforming and restructured loans increased from 1995 through 1996
primarily as a result of acquisitions but decreased in 1997.   Nonperforming and
restructured loans as a percentage of total loans was 0.93% at year-end 1998,
compared to 0.68% at year-end 1997 and 0.98% at year-end 1996.  From a
historical perspective, nonperforming loans peaked in 1986 and have gradually
decreased since that time.  However, it is reasonable to expect that over the
next several years the level of nonperforming loans and loan losses will rise to
more historical norms as a result of economic and credit cycles.

     Nonaccrual loans negatively impact the Company's net interest margin.  A
loan is placed on nonaccrual status when, in the opinion of management, the
future collectibility of interest and/or principal is in serious doubt.
Interest income is recognized on certain of these loans on a cash basis if the
full collection of the remaining principal balance is reasonably expected.
Otherwise, interest income is not recognized until the principal balance is
fully collected.  Total interest income which was not accrued on nonaccrual
loans outstanding at year end was approximately $344,000 in 1998 and $532,000 in
1997.  Only a small amount of this interest was ultimately collected.

     The classification of a loan as nonperforming does not necessarily indicate
that loan principal and interest will ultimately be uncollectible.  The
Company's experience is that a significant portion of both principal and
interest is eventually recovered.  However, the above normal risk associated
with nonperforming loans is considered in the determination of the allowance for
possible loan losses.  At year-end 1998, the allowance for possible loan losses
as a percentage of nonperforming and restructured loans was 158.69%, compared to
206.55% at the end of 1997 and 150.85% at the end of 1996.

     Other real estate owned and repossessed assets decreased in 1998 to $1.64
million from $1.77 million at year-end 1997.  The slight increase in other real
estate owned in 1996 was primarily due to acquisitions during the year.  The
Company places a substantial amount of emphasis on disposing of these assets.
To encourage local management to sell the other real estate as quickly as
possible and to ensure that it is carried at a conservative value, the Company's
policy is to write other real estate down annually by the greater of 10% of its
remaining carrying value, or the difference between its remaining carrying value
and its estimated market value.

     Potential problem loans are performing loans to borrowers with a weakened
financial condition, or which are experiencing unfavorable trends in their
financial condition, which causes management to have concerns as to the ability
of such borrowers to comply with the existing repayment terms.  BancFirst had
approximately $31 million of these loans, which are not included in
nonperforming and restructured assets, at December 31, 1998.  In general, these
loans are well collateralized and have no identifiable loss potential.  Loans
which are considered to have identifiable loss potential are placed on
nonaccrual status, are allocated a specific allowance for loss or are directly
charged-down, and are reported as nonperforming.

Allowance for Possible Loan Losses

     The allowance for possible loan losses reflects Management's assessment of
the risk of loss inherent in the Company's loan portfolio.  The allowance and
its adequacy is determined through consideration of many factors, including
evaluation of known problem loans, levels of adversely classified, past due and
nonperforming loans, loan loss experience, and economic conditions.  To
facilitate Management's assessment, the Company's Asset Quality Department
performs periodic loan reviews at each of the Company's locations.  The process
of determining the adequacy of the allowance for possible loan losses, however,
necessarily involves the exercise of judgment and consideration of numerous
subjective factors and, accordingly, there can be no assurance that the current
level of the allowance will prove adequate in light of future developments and
economic conditions.  As loan quality changes with economic and credit cycles,
it would be reasonable to expect the Company's net charge-offs and loan loss
provisions to return to more historically normal levels.  BancFirst's adversely
classified loans (which includes nonperforming loans, certain restructured loans
and potential problem loans described above) totaled approximately $37.4 million
at the end of 1998, which was equal to 2.79% of total loans.

     The Company's net charge-offs have been very low in recent years.  In 1998,
the Company recognized $1.85million of net charge-offs, which was only 0.14% of
average loans, compared to $2.31 million of net charge-offs, or 0.20% of average
loans, for 1997.

LIQUIDITY AND FUNDING

     The Company's principal source of liquidity and funding is its diverse
deposit base generated from customer relationships.  The availability of
deposits is affected by economic conditions, competition with other financial
institutions and alternative investments available to customers.  Through
interest rates paid, competitive service charges and other banking services
offered, the Company can, to a limited extent, control its level of deposits.
The level and maturity of deposits necessary to support the Company's lending
and investment functions is determined through monitoring loan demand and
through its asset/liability management process.

     The Company's core deposits provide it with a stable, low-cost funding
source.  Total deposits increased $264 million in 1998, and $107 million in
1997, primarily from acquisitions.  Demand deposits as a percentage of total
deposits has been increasing since 1994.  Core deposits as a percentage of total
deposits increased in 1998 to 90.39% from 89.14% in 1997.  In 1996, interest-
bearing transaction deposits decreased and savings deposits increased as a
result of a new product introduced by the Company which sweeps excess funds in
transaction accounts into a savings account.  The effect of this change is even
more apparent in the 1997 and 1998 average balances.

     Short-term borrowings, consisting mainly of federal funds purchased and
repurchase agreements, are another source of funds for the Company.  The level
of these borrowings is determined by various factors, including customer demand
and the Company's ability to earn a favorable spread on the funds obtained.
Short-term borrowings totaled $54.8 million in 1998, compared to $25.7 million
in 1997.  In 1998, the Company expanded its correspondent banking activities.
The increase in short-term borrowings is due largely from federal funds
purchased by correspondent banks.

     In 1995, the Bank became a member of the Federal Home Loan Bank of Topeka,
Kansas (the "FHLB") and began borrowing from the FHLB at favorable interest
rates. These borrowings are collateralized by a pledge of residential first
mortgages. Long-term borrowings increased to $13 million in 1998 from $7.05
million in 1997.

     The Bank is highly liquid. This liquidity positions the Bank to respond to
increased loan demand and other requirements for funds, or to decreases in
funding sources. Cash flows from operations, investing activities and other
funding sources have provided the funds for the increased loan activity.

     The liquidity of BancFirst Corporation is dependent upon dividend payments
from the Bank and its ability to obtain financing. Banking regulations limit
bank dividends based upon net earnings retained by the bank and minimum capital
requirements. Dividends in excess of these limits require regulatory approval.
During 1998, the Bank paid four common stock dividends totaling $10 million and
two preferred stock dividends totaling $1.93 million.

CAPITAL RESOURCES

     Stockholders' equity totaled $202 million at year-end 1998, compared to
$181 million at year-end 1997 and $166 million at year-end 1996.  The increases
in stockholders' equity are primarily due to net earnings retained.  The
Company's average equity capital ratio at year-end 1998 was 9.09%, compared to
8.95% for 1997 and 8.89% for 1996.  At December 31, 1998, the Company's leverage
ratio was 8.54% and its total risk-based capital ratio was 15.57%, compared to
minimum requirements of 3% and 8%, respectively.  Banking institutions are
generally expected to maintain capital well above the minimum levels.

     In January 1997, BancFirst Corporation established BFC Capital Trust I, a
trust formed under the Delaware Business Trust Act. In February 1997, the Trust
issued $25 million of aggregate liquidation amount of 9.65% Capital Securities,
Series A. The proceeds from the sale of the Capital Securities were invested in
9.65% Junior Subordinated Deferrable Interest Debentures, Series A (the
"Debentures") of BancFirst Corporation. The Series A Capital Securities and
Debentures were subsequently exchanged for Series B Capital Securities and
Debentures, pursuant to a Registration Rights Agreement. The terms of the Series
A and Series B securities are identical in all material respects. Distributions
on the Capital Securities are payable January 15 and July 15 of each year. Such
distributions may be deferred for up to ten consecutive semi-annual periods. The
stated maturity date of the Capital Securities is January 15, 2027, but they are
subject to mandatory redemption pursuant to optional prepayment terms. The
Capital Securities represent an undivided interest in the Debentures, are
guaranteed by BancFirst Corporation, and are presented as long-term debt in the
Company's consolidated financial statements, but qualify as Tier 1 regulatory
capital. During any deferral period or during any event of default, BancFirst
Corporation may not declare or pay any dividends on any of its capital stock.

     Future dividend payments will be determined by the Company's Board of
Directors in light of the earnings and financial condition of the Company and
the Bank, their capital needs, applicable governmental policies and regulations
and such other factors as the Board of Directors deems appropriate. While no
assurance can be given as to the Company's ability to pay dividends, Management
believes that, based upon the anticipated performance of the Company, regular
dividend payments will continue in 1999.

MARKET RISK

     Market risk is defined as the risk of loss related to financial instruments
from changes in interest rates, foreign currency exchange rates and commodity
prices. The Company's market risk arises principally from its lending,
investing, deposit and borrowing activities. The Company is not exposed to
market risk from foreign exchange rates and commodity prices. Management
monitors and controls interest rate risk through sensitivity analysis and its
strategy of creating manageable negative interest sensitivity gaps, as described
under "Net Interest Income" above. The Company does not use derivitive financial
instruments to manage its interest rate risk exposure.

     The table below presents the Company's financial instruments that are
sensitive to changes in interest rates, their expected maturities and their
estimated fair values at December 31, 1998.

     The expected maturities and principle repayments are based upon the
contractual terms of the instruments. Prepayments have been estimated for
certain instruments with predictable prepayment rates. Savings and transaction
deposits are assumed to mature all in the first year as they are not subject to
withdrawal restrictions and any assumptions regarding decay rates would be very
subjective. The actual maturities and principle repayments for the financial
instruments could vary substantially from the contractual terms and assumptions
used in the analysis.

YEAR 2000 EXPOSURE

     Many computer systems and devices using embedded computer chips currently
in operation worldwide use only two digits to specify the year. There is a
significant risk that these systems and devices could produce inaccurate
results, or may not function properly, beginning January 1, 2000 when two-digit
year numbers could be processed as being in the previous century. The Company is
exposed to the risk that not only the systems and devices it uses will
malfunction, but also those of its customers, suppliers and other parties with
whom it conducts business. Such malfunctions could expose the Company to losses
from operational errors and failures, as well as customer claims, lawsuits and
regulatory penalties for noncompliance. While the extent of these possible
losses can not be estimated, such losses could have a material adverse effect on
the Company's results of operations, liquidity and financial condition.

     During 1997, the Company commenced a Year 2000 Project to conduct a
comprehensive review of its outside data processing services, internal computer
systems and other mechanical and computerized equipment. The purpose of the
project is to determine and plan for necessary changes to assure that its
systems and equipment will function properly in the year 2000. The project also
includes communications with other parties to determine the extent to which the
parties are addressing the issue and the exposure to the Company in the event
the parties fail to adequately plan for and resolve the issue.

     The plan developed by the Company consists of the following five phases:

          1.  Awareness
          2.  Assessment
          3.  Renovation
          4.  Validation 
          5.  Implementation

                                     A-14
<PAGE>
 
     All five phases of the plan have been completed. Testing of mission
critical applications was completed in March 1999. An evaluation of Year 2000
credit risk has been completed. Contingency plans have been prepared for each
mission critical application.

     The total cost of addressing the Year 2000 issue is not estimated to be
material. The Company's core business applications are provided by a data
processing company that is devoting substantial resources to assure that the
applications are certified as Year 2000 compliant by the end of 1998. Certain of
the other systems either have been replaced, or were already going to be
replaced with newer technology, and their replacement is not being accelerated
due the Year 2000 issue. Also, no significant information technology projects
are being deferred because of the Year 2000 issue.

Private Securities Litigation Reform Act of 1995) with respect to earnings, 
credit quality, year 2000 compliance, corporate objectives, interest rates and 
other financial and business matters. The Company cautions readers that these 
forward-looking statements are subject to numerous assumptions, risks and 
uncertainties, including economic conditions, the performance of financial 
markets and interest rates; legislative and regulatory actions and reforms; 
competition; as well as other factors, all of which change over time. Actual 
results may differ materially from forward-looking statements.

                      REPORTS OF INDEPENDENT ACCOUNTANTS


To the Board of Directors and Stockholders of BancFirst Corporation:

In our opinion, based upon our audits and the report of other auditors, the
accompanying consolidated balance sheets and the related consolidated statements
of income, stockholders' equity and of cash flows present fairly, in all
material respects, the financial position of BancFirst Corporation and its
subsidiaries at December 31, 1998 and 1997, and the results of their operations
and their cash flows for each of the three years in the period ended December
31, 1998, in conformity with generally accepted accounting principles. These
financial statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We did not audit the financial statements of AmQuest Financial
Corporation which statements reflect total assets of $577,074,000 at December
31, 1997 and total revenues of $46,350,000 and $42,291,000 for the years ended
December 31, 1997 and 1996, respectively. Those statements were audited by other
auditors whose report thereon has been furnished to us, and our opinion express
herein, insofar as it relates to the amounts included for AmQuest Financial
Corporation, is based solely on the report of the other auditors. We conducted
our audits of the consolidated financial statements in accordance with generally
accepted auditing standards, which require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits and the report of other auditors provide a reasonable basis for the

To the Board of Directors and Stockholders of BancFirst Corporation:

We have audited the consolidated statement of financial condition of AmQuest
Financial Corp. (an Oklahoma corporation) and subsidiaries as of December 31,
1997, and the related consolidated statements of income, stockholders' equity
and cash flows for each of the two years in the period ended December 31, 1997,
prior to the restatement (and therefore, not presented herein) for the pooling-
of-interests business combination as discussed in Note 2. These consolidated
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statement referred to above present
fairly, in all material respects, the financial position of AmQuest Financial
Corp. and subsidiaries as of December 31, 1997, and the results of their
operations and their cash flows for each of the two years in the period ended
December 31, 1997, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                             (DOLLARS IN THOUSANDS)
                                        

(1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     The accounting and reporting policies of BancFirst Corporation and its
subsidiaries (the "Company") conform to generally accepted accounting principles
and general practice within the banking industry.  A summary of the significant
accounting policies follows.

BASIS OF PRESENTATION

     The accompanying consolidated financial statements include the accounts of
BancFirst Corporation, BancFirst and its subsidiaries BancFirst Investment
Corporation, Lenders Collection Corporation and Express Financial Corporation,
and Kingfisher Bank & Trust Co.  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.  Certain amounts for 1997 and 1996 have been
reclassified to conform with the 1998 presentation.

USE OF ESTIMATES

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

SECURITIES

     The Company does not engage in securities trading activities.  Any sales of
securities are for the purpose of  executing the Company's asset/liability
management strategy, eliminating a perceived credit risk in a specific security,
or providing liquidity.  Securities that are being held for indefinite periods
of time, or that may be sold as part of the Company's asset/liability management
strategy, to provide liquidity or for other reasons, are classified as available
for sale and are stated at estimated market value.  Unrealized gains or losses
on securities available for sale are reported as a component of stockholders'
equity, net of income tax.  Securities for which the Company has the intent and
ability to hold to maturity are classified as held for investment and are stated
at cost, adjusted for amortization of premiums and accretion of discounts
computed under the interest method, unless such investments are considered
permanently impaired, in which case they are adjusted to the lower of cost or
market.  Gains or losses from sales of securities are based upon the book value
of the specific securities sold.

LOANS

     Loans are stated at the principal amount outstanding.  Interest income on
certain installment loans is recorded by use of a method that produces a
reasonable approximation of a constant yield on the outstanding principal.
Interest on all other performing loans is recognized based upon the principal
amount outstanding.

     A loan is placed on nonaccrual status when, in the opinion of management,
the future collectibility of interest and/or principal is in serious doubt.
Interest income is recognized on certain of these loans on a cash basis if the
full collection of the remaining principal balance is reasonably expected.
Otherwise, interest income is not recognized until the principal balance is
fully collected.

              NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONT.)

ALLOWANCE FOR POSSIBLE LOAN LOSSES

     The allowance for possible loan losses is increased by annual provisions
charged to operating expense and is reduced by net loan charge-offs.  The
provision for loan losses charged to operating expense is based on past loan
loss experience and other factors which, in Management's judgement, deserve
current recognition in estimating possible loan losses.  Such other factors
considered by Management include evaluations of known problem loans, levels of
adversely classified and nonperforming loans, and general economic conditions.

     A loan is considered impaired when it is probable that the creditor will be
unable to collect all amounts due according to the contractual terms of the loan
agreement.  The Company's impaired loans are collateral dependent.  Accordingly,
the amount of impairment is measured based upon the fair value of the underlying
collateral and is included in the allowance for possible loan losses.

PREMISES AND EQUIPMENT

     Premises and equipment are stated at cost, less accumulated depreciation.
Depreciation is charged to operating expense and is computed using the straight-
line method over the estimated useful lives of the assets.  Maintenance and
repairs are charged to expense as incurred while improvements are capitalized.
When assets are sold or otherwise retired, the cost and applicable accumulated
depreciation are removed from the respective accounts and any resulting gain or
loss is reflected in operations.

OTHER REAL ESTATE OWNED

     Other real estate owned is comprised of properties acquired through
foreclosure proceedings or acceptance of a deed in lieu of foreclosure.  These
properties are carried at the lower of the book value of the related loan or
fair market value based upon appraisals.  Losses arising at the time of
classification of such properties as other real estate owned are charged
directly to the allowance for possible loan losses.  Losses from declines in
value of the properties subsequent to classification as other real estate owned
are charged directly to operating expense.

INTANGIBLE ASSETS

     Core deposit intangibles are amortized on a straight-line basis over the
estimated useful lives of the core deposits.  The excess of cost over the fair
value of assets acquired (goodwill) is amortized on a straight-line basis over
fifteen to forty years, depending upon when the goodwill originated.
Organization cost and trademarks are amortized on a straight-line basis over
five years and fifteen years, respectively.

INCOME TAXES

     The Company files a consolidated income tax return.   Deferred taxes are
recognized under the asset and liability approach based upon the future tax
consequences of temporary differences between the carrying amounts and tax bases
of assets and liabilities, using the tax rates expected to apply to taxable
income in the periods when the related temporary differences are expected to be
realized.

              NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONT.)

EARNINGS PER COMMON SHARE

     Basic earnings per common share is computed by dividing net income, less
any preferred dividends requirement, by the weighted average of common shares
outstanding, as restated for shares issued in business combinations accounted
for as poolings of interests, if any. Diluted earnings per common share reflects
the potential dilution that could occur if securities or other contracts to
issue common stock were exercised or converted into common stock or resulted in
the issuance of common stock that then shared in the earnings of the Company.

STATEMENT OF CASH FLOWS

     For purposes of the statement of cash flows, the Company considers cash and
due from banks, and interest-bearing deposits with banks as cash equivalents.
Acquisitions accounted for as purchases or as book value purchases are presented
net of any stock issued, assets acquired and liabilities assumed.

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.  The Statement is effective for all fiscal quarters of
fiscal years beginning after June 15, 1999.  The Company does not expect that
the adoption of this standard will have a material impact on its consolidated
financial statements.

     In October 1998, the FASB issued Statement of Financial Accounting
Standards No. 134, "Accounting for Mortgage-Backed Securities Retained after the
Securitization of Mortgage Loans Held for Sale by a Mortgage Banking
Enterprise." This Statement amends Statement of Financial Accounting Standards
No. 65, "Accounting for Certain Mortgage Banking Activities" to require that
after the securitization of Mortgage loans held for sale, an entity engaged in
mortgage banking activities classify the resulting mortgage-backed securities or
other retained interests based on its ability and intent to sell or hold those
investments. The Statement is effective for the first fiscal quarter beginning
after December 15, 1998. The Company does not expect that the adoption of this
standard will have a material impact on its consolidated financial statements.

              NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONT.)

(2)  FORMATION OF BANCFIRST CORPORATION; MERGERS, ACQUISITIONS AND DISPOSALS

     BancFirst Corporation was incorporated in Oklahoma in July 1984.  In June
1985, it merged with seven Oklahoma bank holding companies and has conducted
business as a bank holding company since that time.  Additional mergers and
acquisitions have been completed and, as a result, BancFirst Corporation is the
surviving corporation along with the aforementioned subsidiaries, while the
holding companies, banks and other companies that were merged or acquired ceased
to exist as separate companies.

     In March 1996, BancFirst acquired City Bankshares, Inc. ("City Bankshares")
which had $136,251 in total assets.  The acquisition was for cash of $19,125,
with City Bankshares and its subsidiary bank, City Bank & Trust, being merged
into BancFirst.  C-Teq, Inc., an 85% owned data processing subsidiary of City
Bankshares, was spun off to the shareholders of City Bankshares prior to the
acquisition.  BancFirst also paid the CEO of City Bankshares $1,250 for an
agreement not to compete with BancFirst for a period of four years.  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.  A core deposit intangible of $830 and
goodwill of $7,419 were recorded in the acquisition. The acquisition did not
have a material effect on the results of operations of the Company for 1996.

     In October 1996, the Company acquired all of the assets and assumed all of
the liabilities of Commerce Bancorp which had $17,786 in assets. Commerce
Bancorp was controlled by certain executive officers of the Company. The
acquisition was effected through the exchange of 156,508 shares of BancFirst
Corporation common stock for all of the Commerce Bancorp common stock
outstanding. The minority shares of Commerce Bancorp's subsidiary bank were
purchased for $102. The merger was accounted for as a book value purchase, which
is similar to the pooling of interests method, although the effects of the
merger 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 operations of the Company for 1996.

     In December 1996, the Company acquired 26.75% of the common stock
outstanding of Peoples State Bank of Tulsa, Oklahoma for cash of $770. Peoples
State Bank has approximately $51,000 in total assets. This investment is
accounted for under the equity method of accounting and did not have a material
effect on the results of operations of the Company for 1996.

     In March 1997, the Company acquired 22.8% of the common stock outstanding
of First Ada Bancshares, Inc. for cash of $4,954. First Ada Bancshares, Inc. has
approximately $170,000 in total assets. This investment is accounted for under
the equity method of accounting and did not have a material effect on the
results of operations of the Company for 1997.

     In March 1998, BancFirst completed the purchase of 13 branches from
NationsBank, N.A. and concurrently sold three of the branches to another
Oklahoma financial institution.  The purchase and sale resulted in BancFirst
purchasing loans and other assets of approximately $32,800, assuming deposits of
approximately $132,100 and paying a premium on deposits of approximately $9,100.
The transaction was accounted for as a purchase.  Accordingly, the effects of
the purchase are included in the Company's consolidated financial statements
from the date of the purchase forward.  BancFirst subsequently sold an
additional four of the branches during 1998.  These branches had loans and other
assets of approximately $2,500, and deposits of approximately $54,000.  These
transactions did not have a material effect on the results of operations of the
Company for 1998.

     In May 1998, the Company completed a merger with Lawton Security
Bancshares, Inc. ("Lawton Security Bancshares"), which had approximately $92,000
in total assets. The merger was effected through the exchange of 414,790 shares
of BancFirst Corporation common stock for all of the Lawton Security Bancshares
common stock outstanding, and was accounted for as a pooling of interests.
Accordingly, the consolidated accounts of Lawton Security Bancshares have been
combined with the accounts of the Company and are included in the Company's
consolidated financial statements for all periods presented.

              NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONT.)

     In October 1998, the Company completed a merger with AmQuest Financial
Corp. ("AmQuest") of Duncan, Oklahoma, which had approximately $526,000 in total
assets. The merger was effected through the exchange of 2,522,594 shares of
BancFirst Corporation common stock for all of the AmQuest common stock
outstanding, and was accounted for as a pooling of interests. Accordingly, the
consolidated accounts of AmQuest have been combined with the accounts of the
Company and are included in the Company's consolidated financial statements for
all periods presented. The Company recorded estimated restructuring charges of
$1,912 upon consummation of the merger in October 1998. These charges consist of
termination benefits of $345 for 37 employees terminated and $1,567 for loss on
facilities and other assets to be sold or abandoned. Other merger and conversion
related expenses estimated at $1,200 were incurred. Additionally, the Company
restated AmQuest's allowance for possible loan losses to conform to its own
methodology; accordingly, the allowance for possible loan losses was increased
by $1,400, which was applied retroactively to prior periods.

     Prior to the merger with BancFirst Corporation, AmQuest had made
acquisitions of its own. In March 1996, AmQuest purchased certain assets and
assumed certain liabilities of the Anadarko, Oklahoma branch of First Southwest
Bank. The net purchase price of $398 resulted in total intangible assets of $81.
In April 1997, AmQuest acquired American National Bank of Lawton, which had
total assets of approximately $61,000, for cash of $12,073. This resulted in
total intangible assets of $4,083. Both of these transactions were accounted as
purchases. Accordingly, the effects of the acquisitions are included in the
Company's consolidated financial statements from the dates of the acquisitions
forward. The acquisitions did not have a material effect on the results of
operations of the Company.

     In December 1998, the Company completed the acquisition of Kingfisher
Bancorp, Inc. which had total assets of approximately $91,000. The acquisition
was for cash of $12,000 and 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. A core deposit intangible
of $286 and goodwill of $1,871 were recorded in the acquisition. The acquisition
did not have a material effect on the results of operations of the Company for
1998.

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

(3)  DUE FROM BANKS AND FEDERAL FUNDS SOLD

     The Company maintains accounts with various other financial institutions
and the Federal Reserve Bank, primarily for the purpose of clearing cash items.
Also, it sells federal funds to certain of these institutions on an overnight
basis. As a result, the Company had concentrations of credit risk in four
institutions totaling $142,220 at December 31, 1998 and in two institutions
totaling $39,063 at December 31, 1997. These institutions are selected based on
the strength of their financial condition and their creditworthiness. No
collateral is required on such balances.

     The Company is required, as a matter of law, to maintain a reserve balance
in the form of vault cash or on deposit with the Federal Reserve Bank. The
average amount of reserves maintained for each of the years ended December 31,
1998 and 1997 was approximately $29,151 and $29,200, respectively.

     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 possible 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 possible loan losses in the near term.

these executive officers and directors. Management believes that all such loans
were made on substantially the same terms as those prevailing at the time for
comparable transactions with other persons and do not represent more than a
normal risk of collectibility or present other unfavorable features. A summary
of these loans is as follows:

              NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONT.)

      The Company enters into sales of securities to certain of its customers
with simultaneous agreements to repurchase. These agreements represent an
overnight borrowing of funds.

      The TT&L note is a demand note issued to the U.S. Treasury.

      The Federal Home Loan Bank advances in 1997 matured at various dates
through December 22, 1998.

      The notes payable in 1997 were notes held by trusts controlled by
stockholders of Lawton Security Bancshares. These notes were paid subsequent to
the merger in May 1998.

(10)  LINE OF CREDIT                                        

      AmQuest maintained a $25,000 line of credit specifically for the purpose
of acquiring other financial institutions. Advances would have converted to 10-
year term loans at the lender's reference rate at the time of the advance.
Quarterly principal and interest payments would have been required on the term
loans. The line of credit was secured by the stock of AmQuest's subsidiary banks
and the stock of any other bank acquired with the advances. No advances were
made under the line of credit, and the line of credit was not assumed by the
Company after the merger in October 1998.

(11)  LONG-TERM BORROWINGS

      In 1995 the Company began borrowing under a line of credit from the
Federal Home Loan Bank of Topeka, Kansas in order to match-fund certain long-
term fixed rate loans. Such advances are at rates of from 4.86% to 7.21% and
mature from 2003 through 2013. Interest payments on the advances are due
monthly. Semiannual principal payments on the advances total $1,290 per year. In
December 1996, the Company borrowed $5,000 under the line of credit to fund
general loan growth. This advance was at a rate of 5.97% and matured December
1998. Interest on the advance was payable monthly. Residential first mortgages
are pledged as collateral for the borrowings under the line of credit.

(12)  9.65% CAPITAL SECURITIES

      In January 1997, BancFirst Corporation established BFC Capital Trust I
(the "Trust"), a trust formed under the Delaware Business Trust Act. In February
1997, the Trust issued $25,000 of aggregate liquidation amount of 9.65% Capital
Securities, Series A (the "Capital Securities"). The proceeds from the sale of
the Capital Securities were invested in 9.65% Junior Subordinated Deferrable
Interest Debentures, Series A (the "Debentures") of BancFirst Corporation. The
Series A Capital Securities and Debentures were subsequently exchanged for
Series B Capital Securities and Debentures, pursuant to a Registration Rights
Agreement. The terms of the Series A and Series B securities are identical in
all material respects. Distributions on the Capital Securities are payable
January 15 and July 15 of each year. Such distributions may be deferred for up
to ten consecutive semi-annual periods. The stated maturity date of the Capital
Securities is January 15, 2027, but they are subject to mandatory redemption
pursuant to optional prepayment terms. The Capital Securities represent an
undivided interest in the Debentures, are guaranteed by BancFirst Corporation,
and are presented as long-term debt in the Company's consolidated financial
statements, but qualify as Tier 1 regulator capital. During any deferral period
or during any event of default, BancFirst Corporation may not declare or pay any
dividends on any of its capital stock.

(14)  EMPLOYEE BENEFITS

      In May 1986, the Company adopted the BancFirst Corporation Employee Stock
Ownership and Thrift Plan (the "ESOP") effective January 1, 1985.  The ESOP
covers all eligible employees, as defined in the ESOP, of the Company and its
subsidiaries.  The ESOP allows employees to defer up to 12% of their base
salary, of which the Company may match 50%, but not to exceed 3% of their base
salary.  In addition, the Company may make discretionary contributions to the
ESOP, as determined by the Company's Board of Directors.  The aggregate amounts
of contributions by the Company to the ESOP for the years ended December 31,
1998, 1997 and 1996, were approximately $1,000, $1,050 and $841, respectively.

      Both Lawton Security Bancshares and AmQuest had Section 401(k) plans.
These plans were merged into the ESOP effective January 1, 1999. Contributions
to these plans totaled $576, $545 and $478 for the years ended December 31,
1998, 1997 and 1996.

      BancFirst Corporation also adopted a nonqualified incentive stock option
plan (the "BancFirst ISOP") in May 1986.  In 1998, the Company amended the
BancFirst ISOP to increase the number of shares to be issued under the plan to
850,000.  The options are exercisable beginning four years from the date of
grant at the rate of 25% per year for four years.  Options granted prior to 1996
expire at the end of eleven years from the date of grant.  Options granted after
January 1,  1996 expire at the end of fifteen years from the date of grant.
Options outstanding as of December 31, 1998 will become exercisable through the
year 2005.  The option price must be no less than 100% of the fair market value
of the stock relating to such option at the date of grant.

      The Company applies Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees" ("APB 25") and related
interpretations in accounting for the ISOP. Statement of Financial Accounting
Standards No. 123, "Accounting for Stock-Based Compensation" ("FAS 123") was
issued in 1995 which, if fully adopted by the Company, would change the method
the Company applies in recognizing the cost of the BancFirst ISOP. Adoption of
the cost recognition provisions of FAS 123 is optional and the Company has
elected to not adopt such provisions. However, pro forma disclosures as if the
Company adopted the cost recognition provisions of FAS 123 in 1995 are required
and are presented below. A summary of the options granted under the BancFirst
ISOP is as follows:

      The fair value of each option granted is estimated on the date of grant
using the Black-Scholes option-pricing model with the following weighted average
assumptions: a dividend yield of 1.5%; risk-free interest rates are different
for each grant and range from 4.98% to 7.74%; the expected lives of the options
are from five to ten years; and volatility of the Company's stock price is from
17.77% to 30.98% for all grants.

      The effects of applying FAS 123 to the pro forma disclosure are not
indicative of future results. FAS 123 does not apply to grants of options prior
to 1995 and the Company anticipates making additional grants in the future.

  AmQuest had four stock option plans.  These plans have been assumed by the
Company, but no new options will be issued under the plans.  Pro forma
disclosures, as if the cost recognition provision of FAS 123 had been applied,
have not been presented for these plans since such disclosures would not result
in material differences from the intrinsic value method.  Three of the plans are
qualified incentive stock option plans for employees (the "AmQuest Employees
Stock Option Plans").  A total of 178,135 shares were authorized to be issued
under the plans.  These options became fully vested at the time of the merger
and will expire at various dates through November 2006.  A summary of the
options granted under the AmQuest Employees Stock Option Plans is as follows:

(15)  STOCKHOLDERS' EQUITY

      The following is a description of the capital stock of the Company:

          (a) Senior Preferred Stock: $1.00 par value; 10,000,000 shares
      authorized; no shares issued or outstanding. Shares may be issued with
      such voting, dividend, redemption, sinking fund, conversion, exchange,
      liquidation and other rights as shall be determined by the Company's Board
      of Directors, without approval of the stockholders. The Senior Preferred
      Stock would have a preference over common stock as to payment of
      dividends, as to the right to distribution of assets upon redemption of
      such shares or upon liquidation of the Company.

          (b) 10% Cumulative Preferred Stock: $5.00 par value, redeemable at the
      Company's option at $5.00 per share plus accumulated dividends; non-
      voting; cumulative dividends at the rate of 10% payable semi-annually on
      January 15 and July 15; 900,000 shares authorized; no shares issued or
      outstanding.

          (c) Common stock: $1.00 par value; 15,000,000 shares authorized. At
      December 31, 1998, there were 9,291,929 shares issued and outstanding. At
      December 31, 1997 there were 9,614,004 shares issued and 9,236,875 shares
      outstanding.

      In March 1995, the Company adopted a Stock Repurchase Program (the "SRP")
authorizing management to repurchase up to 200,000 shares of the Company's
common stock.  In 1997 the SRP was amended to increase the shares authorized to
be repurchased to 350,000. The SRP was to be used for purchases of stock by the
Company's ESOP, and could also be used to enhance earnings per share, provide
stock for the exercise of stock options under the Company's ISOP or to provide
additional market liquidity for the stock.  During 1997, the Company purchased
and canceled 37,900 shares and the ESOP purchased 20,000 shares.  No purchases
were made under the SRP during 1996.  The SRP was terminated in April 1998.

      BancFirst Corporation's ability to pay dividends is dependent upon
dividend payments received from BancFirst. Banking regulations limit bank
dividends based upon net earnings retained and minimum capital requirements.
Dividends in excess of these requirements require regulatory approval. At
December 31, 1998, approximately $20,361 of the equity of BancFirst was
available for dividend payments to BancFirst Corporation.

      During any deferral period or any event of default on the 9.65% Capital
Securities, BancFirst Corporation may not declare or pay any dividends on any of
its capital stock.

     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.

     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, 1998 and 1997, 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.

     Loan commitments are agreements to lend to a customer, as long as there is
no violation of any condition established in the contract.  Letters of credit
are conditional commitments issued by the Company to guarantee the performance
of a customer to a third party.  These instruments generally have fixed
expiration dates or other termination clauses and may require payment of a fee.
Since many of the instruments are expected to expire without being drawn upon,
the total amounts do not necessarily represent commitments that will be funded
in the future.

     The Company leases office space in three buildings and two parcels of land
on which it owns buildings. These leases expire at various dates through 2064.
The future minimum rental payments under these leases are as follows:

     Rental expense on all property and equipment rented, including those rented
on a monthly or temporary basis, totaled $1,065, $899 and $868 during 1998, 1997
and 1996, respectively.

     The Company is a defendant in legal actions arising from normal business
activities.  During 1992, BancFirst accrued estimated amounts to settle certain
of these actions.  During 1995 and 1996, these actions were resolved in the
Company's favor and the accruals were reversed.  In 1997, AmQuest accrued $1,250
related to a lawsuit filed in December 1989 involving a bond issue.  The lawsuit
was settled in March 1998 and the amount accrued was paid.  Management believes
that all other legal actions against the Company are without merit or that the
ultimate liability, if any, resulting from them will not materially affect the
Company's financial position, results of operations or cash flows.

(20) FAIR VALUES OF FINANCIAL INSTRUMENTS

     The fair values reported below for financial instruments are based on a
variety of factors.  In some cases, fair values represent quoted market prices
for identical or comparable instruments.  In other cases, fair values have been
estimated based on assumptions concerning the amount and timing of estimated
future cash flows and assumed discount rates reflecting varying degrees of risk.
Accordingly, the fair values may not represent actual values of the financial
instruments that could have been realized as of year end or that will be
realized in the future.

     The following methods and assumptions were used to estimate the fair value
of each class of financial instruments:

CASH AND DUE FROM BANKS; FEDERAL FUNDS SOLD

     The carrying amount of these short-term instruments is a reasonable
estimate of fair value.

SECURITIES

     For securities, fair values are based on quoted market prices or dealer
quotes, if available.  If a quoted market price is not available, fair value is
estimated using quoted market prices for similar securities.

LOANS

     For certain homogeneous categories of loans, such as some residential
mortgages, fair value is estimated using the quoted market prices for securities
backed by similar loans, adjusted for differences in loan characteristics.  For
residential mortgage loans held for sale, guaranteed student loans and
participation in pools of credit card receivables, the carrying amount is a
reasonable estimate of fair value.  The fair value of other types of loans is
estimated by discounting the future cash flows using the current rates at which
similar loans would be made to borrowers with similar credit ratings and for the
same remaining maturities.

DEPOSIT LIABILITIES

  The fair value of transaction and savings accounts is the amount payable on
demand at the reporting date.  The fair value of fixed-maturity certificates of
deposit is estimated using the rates currently offered for deposits of similar
remaining maturities.

SHORT-TERM BORROWINGS

  The amount payable on these short-term instruments is a reasonable estimate of
fair value.

LONG-TERM BORROWINGS

  The fair value of fixed-rate long-term borrowings is estimated using the rates
that would be charged for borrowings of similar remaining maturities.

LOAN COMMITMENTS AND LETTERS OF CREDIT

  The fair value of commitments is estimated using the fees currently charged to
enter into similar agreements, taking into account the terms of the agreements.
The fair value of letters of credit is based on fees currently charged for
similar agreements.

  The estimated fair values of the Company's financial instruments are as
follows:

business units including guaranteed small business lending, guaranteed student
lending, residential mortgage lending, trust services, correspondent banking and
electronic banking. The executive, operations and support groups represent
executive management, operational support and corporate functions that are not
allocated to the other business units. The results of operations and selected

              NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONT.)
                                        
     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 services
provided by the support group to other business units, such as item processing,
are allocated rates approximating the cost of providing the services.
Eliminations are adjustments to consolidate the business units and companies.
In 1998, the costs related to the AmQuest merger have been segregated because of
their impact on the results of executive, operations and support.  Capital
expenditures are generally charged to the business unit using the asset.

Stock since the immediately preceding Quarterly Dividend Payment Date, or with
respect to the first Quarterly Dividend Payment Date, since the first issuance
of a share of Series A Preferred Stock. If the Quarterly Dividend Payment Date
is a Saturday, Sunday or legal holiday, then such Quarterly Dividend Payment
Date shall be the first immediately preceding calendar day which is not a
Saturday, Sunday or legal holiday. In the event that the Company shall at any
time after February 25, 1999 (the "Rights Declaration Date") (i) declare any
dividend on outstanding shares of Common Stock payable in shares of Common
Stock, (ii) subdivide outstanding shares of Common Stock or (iii) combine
outstanding shares of Common Stock into a smaller number or shares, then in each
such case, the amount to which the holder of a share of Series A Preferred Stock
was entitled immediately prior to such event pursuant to the preceding sentence
shall be adjusted by multiplying such amount by a fraction, the numerator of
which shall be the number of shares of Common Stock that are outstanding
immediately after such event, and the denominator of which shall be the number
of shares of Common Stock that were outstanding immediately prior to such event.

<PAGE>
 
     (B)   The Company shall declare a dividend or distribution on shares of 
Series A Preferred Stock as provided in paragraph (A) above immediately after it
declares a dividend or distribution on the shares of Common Stock (other than a 
dividend payable in shares of Common Stock); PROVIDED, HOWEVER, that, in the
event no dividend or distribution shall have been declared on the Common Stock
during the period between any Quarterly Dividend Payment Date and the next
subsequent Quarterly Dividend Payment Date, a dividend of $5.00 per share on the
Series A Preferred Stock shall nevertheless be payable on such subsequent
Quarterly Dividend Payment Date.

     (C)   Dividends shall begin to accrue and shall be cumulative on each 
outstanding share of Series A Preferred Stock from the Quarterly Dividend 
Payment Date next preceding the date of issuance of such share of Series A 
Preferred Stock, unless the date of issuance of such share is prior to the 
record date for the first Quarterly Dividend Payment Date, in which case, 
dividends on such share shall begin to accrue from the date of issuance of such
share, or unless the date of issuance is a Quarterly Dividend Payment Date or is
a date after the record date for the determination of holders of shares of 
Series A Preferred Stock entitled to receive a quarterly dividend and before 
such quarterly Dividend Payment Date, in either of which events such dividends 
shall begin to accrue and be cumulative from such Quarterly Dividend Payment 
Date. Accrued but unpaid dividends shall not bear interest. Dividends paid on 
shares of Series A Preferred Stock in an amount less than the aggregate amount 
of all such dividends at the time accrued and payable on such shares shall be 
allocated pro rata on a share-by-share basis among all shares of Series A 
Preferred Stock at the time outstanding. The Board of Directors may fix a record
date for the determination of holders of shares of Series A Preferred Stock 
entitled to receive payment of a dividend or distribution declared thereon, 
which record date shall be no more than 60 days prior to the date fixed for the
payment thereof.

     (D)   Dividends payable on the Series A Preferred Stock for the initial 
dividend period and for any period less than a full quarterly period, shall be 
computed on the basis of a 360-day year of 30-day months.

     SECTION 3.  VOTING RIGHTS. The holders of shares of Series A Preferred 
Stock shall have the following voting rights.

     (A)   Each share of Series A Preferred Stock shall entitle the holder 
thereof to one vote on all matters submitted to a vote of the shareholders of 
the Company.

     (B)   Except as otherwise provided herein or by law, the holders of shares 
of Series A Preferred Stock and the holders of shares of Common Stock shall vote
together as one class on all matters submitted to a vote of shareholders of the 
Company.

     (C)   If at the time of any annual meeting of shareholders for the election
of directors a "default in preference dividends" on the Series A Preferred Stock
shall exist, the holders of the Series A Preferred Stock shall have the right at
such meeting, voting together as a single class, to the exclusion of the holders
of Common Stock, to elect two (2) directors of the Company.  Such right shall 
continue until there are no dividends in arrears upon the Series A Preferred 
Stock.  Either or both of the two directors to be elected by the holders of the 
Series A Preferred Stock may be to fill a vacancy or vacancies created by an 
increase by the Board of Directors in the number of directors constituting the 
Board of Directors.  Each director elected by the holders of Preferred Stock 
(a "Preferred Director") shall continue to serve as such director for the full 
term for which he or she shall have been elected, notwithstanding that prior to
the end of such term a default in preference dividends shall cease to exist. Any
Preferred Director may be removed by, and shall not be removed except by, the
vote of the holders of record of the outstanding Series A Preferred Stock voting
together as a single class, at a meeting of the shareholders or of the holders
of Preferred Stock called for the purpose. So long as a default in preference
dividends on the Series A Preferred Stock shall exist, (i) any vacancy in the
office of a Preferred Director may be filled (except as provided in the
following clause (ii)) by an instrument in writing signed by the remaining
Preferred Director and filed with the Company and ii) in the case of the removal
of any Preferred Director, the vacancy may be filled by the vote of the holders
of the outstanding Series A Preferred Stock voting together as single class, at
the same meeting at which such removal shall be voted. Each director appointed
as aforesaid by the remaining Preferred Director shall be


                                       2
     
     
<PAGE>
 
deemed, for all purposes hereof, to be a Preferred Director.  For the purposes 
hereof, a "default in preference dividends" on the Preferred Stock shall be 
deemed to have occurred whenever the amount of accrued and unpaid dividends upon
the Series A Preferred Stock shall be equivalent to six (6) full quarterly 
dividends or more, and having so occurred, such default shall be deemed to exist
thereafter until, but only until, all accrued dividends on all Series A 
Preferred Stock then outstanding shall have been paid to the end of the last 
preceding quarterly dividend period.  The provisions of this paragraph (C) shall
govern the election of Directors by holders of Series A Preferred Stock during 
any default in preference dividends notwithstanding any provisions of the 
Company's Certificate of Incorporation to the contrary.

     (D)   Except as set forth herein, holders of shares of Series A Preferred 
Stock shall have no special voting rights and their consent shall not be
required (except to the extent they are entitled to vote with holders of shares
of Common Stock as set forth herein) for taking any corporate action.

     SECTION 4.  CERTAIN RESTRICTIONS

     (A)   Until all accrued and unpaid dividends and distributions, whether or 
not declared, on outstanding shares of Series A Preferred Stock shall have been 
paid in full, the Company shall not:

           (i)    declare or pay dividends on, make any other distributions on, 
     or redeem or purchase or otherwise acquire for consideration any shares of 
     junior stock;

           (ii)   declare or pay dividends on or make any other distributions on
     any shares of parity stock, except dividends paid ratably on shares of
     Series A Preferred Stock and shares of all such parity stock on which
     dividends are payable or in arrears in proportion to the total amounts to
     which the holders of such Series A Preferred Stock and all such shares are
     then entitled;

           (iii)  redeem or purchase or otherwise acquire for consideration 
     shares of any junior stock, PROVIDED, HOWEVER, that the Company may at any
     time redeem, purchase or otherwise acquire shares of any such junior stock
     in exchange for shares of any other junior stock;

           (iv)   purchase or otherwise acquire for consideration any shares of 
     Series A Preferred Stock or any shares of parity stock, except in
     accordance with a purchase offer made in writing or by publication (as
     determined by the Board of Directors) to all holders of such shares upon
     such terms as the Board of Directors, after consideration of the respective
     annual dividend rates and other relative rights and preferences of the
     respective series and classes, shall determine in good faith will result in
     fair and equitable treatment among the respective series or classes.

     (B)   The Company shall not permit any subsidiary of the Company to 
purchase or otherwise acquire for consideration any shares of stock of the 
Company unless the Company could, under paragraph (A) of this Section 4, 
purchase or otherwise acquire such shares at such time and in such manner.

     SECTION 5.  REACQUIRED SHARES.  Any shares of Series A Preferred Stock 
purchased or otherwise acquired by the Company in any manner whatsoever shall be
retired and canceled promptly after the acquisition thereof.  All such shares 
shall upon their cancellation become authorized but unissued Preferred Stock and
may be reissued as part of a new series of Preferred Stock subject to the 
conditions and restrictions on issuance set forth in the Certificate of 
Incorporation of the Company creating a series of Preferred Stock or any similar
shares or as otherwise required by law.

     SECTION 6.  LIQUIDATION, DISSOLUTION OR WINDING UP.

     (A)   Upon any voluntary or involuntary liquidation, dissolution or winding
up of the Company, no distributions shall be made (i) to the holders of shares 
of junior stock unless the holders of Series A Preferred Stock shall have 
received, subject to adjustment as hereinafter provided in paragraph (B), the 
greater or either (a) $100.00 per share plus an amount equal to accrued and 
unpaid dividends and distributions thereon, whether or not

                                       3
<PAGE>
 
declared, to the date of such payment, or (b) an amount per share equal to 100 
times the aggregate per share amount to be distributed to holders of shares of 
Common Stock or (ii) to the holders of shares of parity stock, unless 
simultaneously therewith distributions are made ratably on shares of Series A 
Preferred Stock and all other shares of such parity stock in proportion to the 
total amounts to which the holders of shares of Series A Preferred Stock are 
entitled under clause (i)(a) of this Sentence and to which the holders of shares
of such parity stock are entitled, in each case, upon such liquidation, 
dissolution or winding up.

     (B)   In the event the Company shall at any time after the Rights 
Declaration Date (i) declare any dividend on outstanding shares of Common Stock 
payable in shares of Common Stock, (ii) subdivide outstanding shares of Common 
Stock, or (iii) combine outstanding shares of Common Stock into a smaller number
of shares, then in each such case, the aggregate amount to which holders of 
Series A Preferred Stock were entitled immediately prior to such event pursuant 
to clause (i)(b) of paragraph (A) of this Section 6 shall be adjusted by 
multiplying such amount by a fraction, the numerator of which shall be the 
number of shares of Common Stock that are outstanding immediately after such 
event, and the denominator of which shall be the number of shares of Common 
Stock that were outstanding immediately prior to such event.

     SECTION 7.  CONSOLIDATION, MERGER, ETC.  In case the Company shall enter 
into any consolidation, merger, combination or other transaction in which the 
shares of Common Stock are exchanged for or converted into other stock or 
securities, cash and/or any other property, then in any such case, each share of
Series A Preferred Stock shall at the same time be similarly exchanged for or 
converted into an amount per share (subject to the provision for adjustment 
hereinafter set forth) equal to 100 times the aggregate amount of stock, 
securities, cash and/or any other property (payable in kind), as the case may 
be, into which or for which each share of Common Stock is converted or 
exchanged.  In the event the Company shall at any time after the Rights 
Declaration Date (i) declare any dividend on outstanding shares of Common Stock 
payable in shares of Common Stock, (ii) subdivide outstanding shares of Common 
Stock, or (iii) combine outstanding shares of Common Stock into a smaller number
of shares, then in each such case, the amount set forth in the immediately 
preceding sentence with respect to the exchange or conversion of shares of 
Series A Preferred Stock shall be adjusted by multiplying such amount by a 
fraction, the numerator of which shall be the number of shares of Common Stock 
that are outstanding immediately after such event, and the denominator of which 
shall be the number of shares of Common Stock that were outstanding immediately 
prior to such event.

     SECTION 8.  REDEMPTION.  The shares of Series A Preferred Stock shall not 
be redeemable.

     SECTION 9.  RANKING.  The shares of Series A Preferred Stock shall rank 
junior to all other series of the Preferred Stock and to any other class of 
preferred stock that hereafter may be issued by the Company as to the payment of
dividends and the distribution of assets, unless the terms of any such series or
class shall provide otherwise.

     SECTION 10. AMENDMENT.  The provisions of this Certificate of Designation 
shall not hereafter be amended, either directly or indirectly, or through merger
or consolidation with another corporation, in any manner that would alter or 
change the powers, preferences or special rights of the Series A Preferred Stock
so as to affect them adversely without the affirmative vote of the holders of at
least a majority of the outstanding shares of Series A Preferred Stock, voting 
separately as a class.

     SECTION 11. FRACTIONAL SHARES. The Series A Preferred Stock may be issued 
in fractions of a share, which fractions shall entitle the holder, in proportion
to such holder's fractional shares, to exercise voting rights, receive 
dividends, participate in distributions, and to have the benefit of all other 
rights of holders of Series A Preferred Stock.

     SECTION 12. CERTAIN DEFINITIONS. As used herein with respect to the Series 
A Preferred Stock, the following terms shall have the following meanings:

     (A)   The term "junior stock" (i) as used in Section 4, shall mean the 
Common Stock and any other class or series of capital stock of the Company 
hereafter authorized or issued over which the Series A Preferred

                                       4
<PAGE>
 
Stock has preference or priority as to the payment of dividends, and (ii) as 
used in Section 6, shall mean the Common Stock and any other class or series of 
capital stock of the Company over which the Series A Preferred Stock has 
preference or priority in the distribution of assets on any liquidation, 
dissolution or winding up of the Company.

        (B)    The term "parity stock" (i) as used in Section 4, shall mean any 
class or series of stock of the Company hereafter authorized or issued ranking 
PARI PASSU with the Series A Preferred Stock as to dividends, and (ii) as used 
in Section 6, shall mean any class or series of stock of the Company ranking 
PARI PASSU with the Series A Preferred Stock in the distribution of assets on 
any liquidation, dissolution or winding up.

        IN WITNESS WHEREOF, BancFirst Corporation has caused this Certificate to
be signed and arrested on this 25th day of February, 1999.
