PART I
ITEM 1 - BUSINESS

General Development of Business

BOK Financial Corporation ("BOK Financial") was incorporated under the
laws of the State of Oklahoma on October 24, 1990. Active operations as a
bank holding company commenced on June 7, 1991 with the acquisition of
the preferred stock ("BOk Preferred Stock") of Bank of Oklahoma, National
Association ("BOk") from the Federal Deposit Insurance Corporation
("FDIC") and the conversion of the BOk Preferred Stock into 99.99% of the
common stock of BOk. BOK Financial is regulated by the Board of Governors
of the Federal Reserve System pursuant to the Bank Holding Company Act of
1956, as amended ("BHCA").

BOK Financial operates primarily through BOk, BOk's subsidiaries, Bank of
Texas, National Association ("BOT") (formerly First National Bank of Park
Cities and First Texas Bank, both of which were acquired during 1997 and
merged on January 1, 1998, and Bank of Texas Trust Company, National
Association, formerly Alliance Trust Company, National Association), and
Bank of Arkansas, National Association ("BOA") (formerly Citizens Bank of
Northwest Arkansas, National Association). The existing and future
activities of BOK Financial and its subsidiaries are limited by the BHCA,
which prohibits a bank holding company from engaging in any business
other than banking, managing or controlling banks, and furnishing and
performing certain bank-related services and activities.

Shares disclosed in the following transactions have not been restated
for subsequent stock dividends.

On June 7, 1991, BOK Financial paid $60.75 million to the FDIC for the
BOk Preferred Stock. To finance this acquisition, BOK Financial issued
preferred stock totaling $15.0 million at $6.00 per share and common
stock ("Common Stock") totaling $46.0 million at $5.75 per share to
George B. Kaiser ("Kaiser"), BOK Financial's principal shareholder.
Kaiser purchased an additional $10.0 million of BOK Financial Common
Stock at $5.75 per share, and BOK Financial contributed the $10.0 million
to BOk as additional capital. Per share amounts reflect a 1-for-100
reverse stock split effective December 17, 1991 ("reverse stock split").

Following a bidding process conducted by the Resolution Trust Corporation
("RTC"), BOK Financial, through the mortgage banking subsidiary of BOk,
BancOklahoma Mortgage Corp. ("BOMC"), acquired on June 10, 1991
approximately $1.0 billion of mortgage servicing rights and certain other
assets of Maxim Mortgage Corporation ("Maxim"). Maxim was formerly a
subsidiary of Sooner Federal Savings and Loan Association, which had
failed and had been placed under the control of the RTC.

Also following a bidding process by the RTC, BOK Financial acquired on
August 9, 1991 certain assets and assumed certain liabilities, primarily
deposits, of eight branches of Continental Federal Savings and Loan
Association of Oklahoma City, Oklahoma. BOK Financial assumed deposits of
approximately $214.5 million and paid the RTC a premium of $4.1 million.
Kaiser acquired an additional $20.0 million of BOK Financial's Common
Stock at $5.75 per share (after effect of the reverse stock split), and
BOK Financial contributed the $20.0 million to BOk to facilitate the
purchase.

On March 27, 1992, BOA acquired certain assets and assumed the deposits
and certain obligations of two branches of the failed Home Federal
Savings & Loan Association from the RTC for $1.1 million.

On July 16, 1992, Bank of Oklahoma, N.A., South, an unconsolidated
banking subsidiary, was merged into BOk.

On November 13, 1992, BOK Financial purchased Southwest Trustcorp, Inc.
and its subsidiary, The Trust Company of Oklahoma, Oklahoma City, in
exchange for 400,000 shares of Common Stock valued at $4.6 million.

On December 31, 1992, BOK Financial acquired certain assets and assumed
$502.9 million of deposits and other liabilities of 19 branches of the
Sooner Division of First Gibraltar Bank, FSB of Irving, Texas for a
purchase price of $16.5 million.

On May 7, 1993, BOK Financial issued 343,295 common shares valued at $6.9
million and paid $3.9 million to acquire Sand Springs Bancshares, Inc.
and its subsidiary, Sand Springs State Bank.

Also on May 7, 1993, BOK Financial issued 1,183,691 common shares to
acquire Brookside Bancshares, Inc. and its subsidiary, Brookside State
Bank, in a pooling-of-interests transaction. Financial information of BOK
Financial for 1992 and 1991 has been restated to reflect this
acquisition.

On October 9, 1993, BOK Financial acquired certain assets and assumed the
deposits and certain obligations of two branches of the failed Heartland
Federal Savings & Loan Association from the FDIC for $5.1 million.

On May 2, 1994, BOK Financial acquired Plaza National Bank, Bartlesville,
Oklahoma for $11.7 million.

On June 13, 1994, BOK Financial acquired Texas Commerce Trust Company -
Sherman, National Association, Sherman, Texas, a national association
limited to trust powers only, for $6.1 million.
4

On October 7, 1994, BOK Financial acquired Northwest Bank of Enid, Enid,
Oklahoma for $8.2 million.

On November 14, 1994, BOK Financial issued 1,380,017 common shares to
acquire Citizens Holding Company and its subsidiaries, Citizens Bank of
Muskogee and Citizens Bank of Northwest Arkansas, in a
pooling-of-interests. Financial information of BOK Financial for 1993 and
1992 has been restated to reflect this acquisition.

On February 12, 1997, BOK Financial acquired Park Cities Bancshares, Inc.
and its subsidiary, First National Bank of Park Cities, in Dallas, Texas
for $50.9 million.

On March 4, 1997, BOK Financial acquired First TexCorp., Inc. and its
subsidiary, First Texas Bank, in Dallas, Texas for $39.3 million.

On January 1, 1998, First National Bank of Park Cities and First Texas
Bank were merged under the name of Bank of Texas, National Association
and Alliance Trust Company, National Association was transferred to BOT
and its name changed to Bank of Texas Trust Company, National
Association.

Developments relating to individual aspects of the business of BOK
Financial are described under "Narrative Description of Business" and
"Services Offered" on page 4 of this report. Additional discussion of BOK
Financial's activities during the current year is incorporated by
reference to "Management's Assessment of Operations and Financial
Condition" (pages 6 - 18) in BOK Financial's 1997 Annual Report to
Shareholders. Additional information regarding BOK Financial's
acquisitions is incorporated by reference to Note 2 of "Notes to
Consolidated Financial Statements" (page 28 ) in BOK Financial's 1997
Annual Report to Shareholders.

Narrative Description of Business

BOK Financial is a bank holding company, and as such, its activities are
limited by the BHCA to banking, certain bank-related services and
activities, and managing or controlling banks. BOK Financial's banking
and bank-related activities are primarily performed through BOk, BOT and
BOA. Other significant operating subsidiaries include BOK Capital
Services Corporation, which provides leasing and mezzanine financing and
Alliance Securities Corporation which is authorized to underwrite
municipal revenue bonds, asset-backed securities and commercial paper.
Other nonbank subsidiary operations are not significant. As of December
31, 1997, BOK Financial and its subsidiaries had 2,318 full-time
equivalent employees. Following is a description of the more significant
services offered by BOK Financial and the competitive and regulatory
environments in which it operates.

Services Offered

Commercial Banking Services

BOK Financial, through BOk, BOT and BOA, provides a wide range of
financial services to commercial and industrial customers, including
depository, lending and other financial services such as cash management,
leasing and international collections. The loan portfolio is comprised
primarily of real estate and commercial loans. The commercial loan
portfolio is diversified and distributed among various commercial and
industrial customers, including energy-related, manufacturing, trade and
service industries.

Correspondent Banking Services

BOK Financial provides a broad range of financial services to banks,
savings and loans, credit unions and other financial institutions in
Oklahoma and surrounding states. BOK Financial works closely with
community financial institutions, assisting them in satisfying the
demands of their customers and trade areas by engaging in loan
participations and providing other financial services.

Consumer Banking Services

At December 31, 1997, BOk had 65 banking locations, with 45 locations in
the Tulsa and Oklahoma City areas. BOT had 4 offices in Dallas and
another trust office in Sherman, Texas, and BOA had 4 locations in
northwest Arkansas. Services offered include deposit accounts,
installment loans, student loans, personal lines of
credit, debit cards, an automated 24-hour telephone loan application
service, a 24-hour telephone branch and telephone and personal computer
based bill paying services. The BancOklahoma Investment Center makes
available, through representatives in most BOk branches, a full range of
mutual funds, annuities and securities. TransFund, BOk's network of
automated teller machines, consists of 782 locations across Oklahoma,
Arkansas, southwest Missouri, northern Texas and southern Kansas.

Investment and Money Market Activities

BOk provides securities brokerage, and trading services for corporations,
governmental units, individual customers and correspondent banks.
Securities include money market instruments, U.S. Government and
municipal bonds, corporate stocks
5

and bonds, and mutual funds. The public
finance department provides bank-eligible underwriting financial
advisory, private placement and term-financing services for governmental
and corporate entities. BOK Financial provides a broad range of financial
services outside those traditionally associated with banking through its
subsidiaries Alliance Securities Corp., which is authorized to provide
financial advisory services to both public and corporate sectors,
underwriting of municipal revenue bonds, mortgage backed debt, consumer
receivables, and commercial paper; and BOK Capital Services Corp. which
provides leasing and mezzanine financing.


Mortgage Banking

BOk through its Mortgage Division (formerly BancOklahoma Mortgage Corp.)
offers a full array of mortgage options from federally sponsored programs
to "jumbo loans" on higher priced houses. BOk is the largest originator
of mortgage loans in Oklahoma and has a servicing portfolio of
approximately $7.0 billion, including $216 million serviced for BOk.

Trust and Asset Management Services

BOK Financial provides a wide range of trust services through BOk's Trust
Division (formerly BancOklahoma Trust Company) in Oklahoma and BOT's Bank
of Texas Trust Company, N.A. in Texas (formerly Alliance Trust Company,
N.A.) Individual financial trust services include personal trust
management, administration of estates and management of individual
investment and custodial accounts. For corporate clients, the services
include management, administration and recordkeeping of pension plans,
thrift plans, 401(k) plans and master trust plans, including a
state-of-the-art system for employee benefit plan recordkeeping. The BOk
trust division also serves as transfer agent and registrar for corporate
securities, paying agent for municipalities and governmental agencies and
indenture trustee of bond issues. The BOK Trust Division serves as an
investment advisor to the American Performance Funds, a family of
proprietary mutual funds distributed by the Winsbury Company of Columbus,
Ohio. At December 31, 1997, trust subsidiaries were responsible for
approximately $11.1 billion in assets.

Foreign Operations

BOK Financial does not engage in operations in foreign countries, nor
does it lend to foreign governments.

Competition

The banking industry in Oklahoma is highly competitive. BOK Financial
competes with other banks in obtaining deposits, making loans and
providing additional services related to banking. There are approximately
320 banks located in Oklahoma, of which approximately 38 are located in
the Tulsa County and surrounding metropolitan area and approximately 53
are located in the Oklahoma County and surrounding metropolitan area. BOK
Financial is also in competition with other businesses engaged in
extending credit or accepting deposits, such as major retail
establishments, major brokerage firms, savings and loan associations,
credit unions, finance companies, small loan companies, insurance
companies and loan production offices of major banks located within and
outside Oklahoma.

Limited branch banking as permitted in Oklahoma is increasing
competition. Generally, a bank may establish two new branch offices
within the town or city where the bank is located or in nearby areas not
already served by a bank or branch, and may acquire an unlimited number
of existing banks and convert them and their branches into branch
offices. Within its primary markets, BOk has 23 locations in the Tulsa
area and 22 locations in the Oklahoma City area, the state's largest
financial markets. Subject to regulatory approval, BOk is considering
various locations for additional facilities. Like BOk, other banks are
taking advantage of the bank branching laws to establish additional
facilities. These additional banking offices are further increasing
competition. Limited branch banking is, on the other hand, permitting
banks to compete more effectively with savings and loan associations,
credit unions and other financial institutions that may establish offices
more freely than banks, some of which are not subject to comparable
regulatory restrictions on their activities.

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 multibank holding company do not exceed 15% of all
deposits in Oklahoma financial institutions insured by the federal
government, exclusive of credit union deposits. Based on the latest
statistical data available (as of June 30, 1997), BOK Financial could
acquire additional bank subsidiaries so long as the aggregate deposits of
all Oklahoma subsidiaries do not exceed approximately $5.2 billion.
Deposits of BOk were $3.2 billion and $3.3 billion at June 30, and
December 31, 1997, respectively.

Oklahoma also permits out-of-state bank holding companies to acquire
banks and bank holding companies located in the state and, subject to
certain limitations, make additional acquisitions within the state.
During the last few years the Oklahoma banking industry has been
consolidated into fewer but larger banks. During 1997, two
"super-regional" holding companies completed acquisitions of the second
and third largest banks in Oklahoma. The consolidation over the past
several years has brought about a highly competitive environment, in
which many customers have access to national and regional financial
institutions for many products and services.

On September 29, 1994, the Riegle-Neal Interstate Banking and Branching
Efficiency Act of 1994 ("Riegle-Neal") was signed into law. In summary,
commencing one year after passage, qualifying bank holding companies were
permitted to acquire
6

banks in any state. As of June 1, 1997,
qualifying banks were able to engage in interstate branching by merging
banks in different states. States " opt-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. The law imposes a 10% nationwide
deposit cap and a 30% state deposit cap; however, the states' authority
is preserved to impose a lower, nondiscriminatory deposit cap. Oklahoma
elected to "opt-in" to interstate branching effective May 1997 and
established a 12.25% deposit cap which was subsequently increased to 15%.
It is anticipated that the total number of Oklahoma banks may decrease
and national and regional bank presence in the state may increase. Over
the near-term, these changes are expected to increase competition with a
greater number of products and services available to Oklahoma customers.
Over the long-term, the number of competitors could decrease, depending
on the extent of consolidations nationwide, but competition could
continue to increase as a result of the remaining institutions needing to
be stronger, more innovative and more aggressive to retain a significant
presence in a consolidated environment.

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
BOK Financial or its subsidiaries, or upon the Oklahoma regional banking
environment.

Supervision and Regulation

Bank holding companies and banks are extensively regulated under both
federal and state law. The following information, to the extent it
describes statutory or regulatory provisions, is qualified in its
entirety by reference to the particular statutory and regulatory
provisions. It is not possible to predict the changes, if any, that may
be made to existing banking laws and regulations or whether such changes,
if made, would have a materially adverse effect on the business and
prospects of BOK Financial, BOk, BOT and BOA.

BOK Financial

As a bank holding company, BOK Financial is subject to regulation under
the BHCA and to supervision by the Board of Governors of the Federal
Reserve System (the "Reserve Board"). Under the BHCA, BOK Financial is
required to file with the Reserve Board an annual report and such other
additional information as the Reserve Board may require. The Reserve
Board may also make examinations of BOK Financial and its subsidiaries.

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.

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 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 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 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-payout, 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
7

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 Deposit Insurance Corporation Improvement Act of 1991
established five capital rating tiers ranging from "well capitalized" to
"critically undercapitalized". A financial institution is considered to
be well capitalized if its Leverage, Tier 1 and Total Capital ratios are
at 5%, 6% and 10%, respectively. Any institution experiencing significant
growth or acquiring other institutions or branches is expected to
maintain capital ratios above the well capitalized level. At December 31,
1997, BOK Financial's Leverage, Tier 1 and Total Capital ratios were
6.81%, 9.39% and 14.54%, respectively.

Bank Subsidiaries

BOk, BOT and BOA are national banking associations and are subject to the
National Banking Act and other federal statutes governing national banks.
Under federal law, the Office of the Comptroller of the Currency
("Comptroller") charters, regulates and serves as the primary regulator
of national banks. In addition, the Comptroller must approve certain
corporate or structural changes, including an increase or decrease in
capitalization, payment of dividends, change of place of business,
establishment of a branch and establishment of an operating subsidiary.
The Comptroller performs its functions through national bank examiners
who provide the Comptroller with information concerning the soundness of
a national bank, the quality of management and directors, and compliance
with applicable laws, rules and regulations. The National Banking Act
authorizes the Comptroller to examine every national bank as often as
necessary. Although the Comptroller has primary supervisory
responsibility for national banks, such banks must also comply with
Reserve Board rules and regulations as members of the Federal Reserve
System.

BOA is also subject to certain consumer-protection laws incorporated in
the Arkansas Constitution, which, among other restrictions, limit the
maximum interest rate on general loans to five percent above the Federal
Reserve Discount Rate. The rate on consumer loans is five percent above
the discount rate or seventeen percent, whichever is lower.

BOk, BOT and BOA are insured by the FDIC and are required to pay certain
fees and premiums to the Bank Insurance Fund ("BIF"). The BIF has
implemented a risk-related insurance system for determining premiums to
be paid by a bank. Each bank is placed in one of nine risk categories
based on its level of capital and supervisory rating 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. Also, approximately 19% of BOK
Financial's total deposits at December 31, 1997 were acquired through
Oakar transactions and are insured through the Savings Association
Insurance Fund ("SAIF"). The Deposit Insurance Funds Act of 1996 was
enacted on September 30, 1996, which recapitalized the SAIF and
implemented a risk-related insurance system identical to the BIF system
discussed above. In addition, the Deposit Insurance Fund Act of 1996
implemented an additional assessment on BIF and SAIF deposits, the
Financing Corporation ("FICO") Quarterly Payment, which is not tied to
the BIF risk classification. The FICO BIF annual rate at December 31,
1997 was 1.256 basis points and the FICO SAIF annual rate was 6.28 basis
points.

Applicable federal statutes and regulations require national banks to
meet certain leverage and risk-based capital requirements. At December
31, 1997, BOk's, BOT's and BOA's leverage and risk-based capital ratios
were well above the required minimum ratios.

Governmental Policies and Economic Factors

The operations of BOK Financial and its subsidiaries are affected by
legislative changes and by the policies of various regulatory authorities
and, in particular, the credit policies of the Reserve Board. An
important function of the Reserve Board is to regulate the national
supply of bank credit. Among the instruments of monetary policy used by
the Reserve Board to implement its objectives are: open market operations
in U.S. Government securities; changes in the discount rate on bank
borrowings; and changes in reserve requirements on bank deposits. The
effect of such policies in the future on the business and earnings of BOK
Financial and its subsidiaries cannot be predicted with certainty.

ITEM 2 - PROPERTIES

BOK Financial, through BOk, BOk's subsidiaries, BOT and BOA, owns
improved real estate that was carried at $43.0 million, net of
depreciation and amortization, as of December 31, 1997. BOK Financial
conducts its operations through a total of 65 banking and 4 nonbanking
locations in Oklahoma, 4 banking locations in Arkansas and 4 banking and
