             Report of Independent Registered Public Accounting Firm

The Plan Administrative Committee
BOK Financial Thrift Plan for Hourly Employees

We have audited the accompanying statements of net assets available for benefits
of the BOK Financial Thrift Plan for Hourly Employees as of December 31, 2003
and 2002, and the related statement of changes in net assets available for
benefits for the year ended December 31, 2003. These financial statements are
the responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards 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. 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 financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan at
December 31, 2003 and 2002, and the changes in its net assets available for
benefits for the year ended December 31, 2003, in conformity with U.S. generally
accepted accounting principles.

Our audits were performed for the purpose of forming an opinion on the financial
statements taken as a whole. The accompanying supplemental schedule of assets
(held at end of year) as of December 31, 2003, is presented for purposes of
additional analysis and is not a required part of the financial statements but
is supplementary information required by the Department of Labor's Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974. This supplemental schedule is the responsibility of the
Plan's management. The supplemental schedule has been subjected to the auditing
procedures applied in our audits of the financial statements and, in our
opinion, is fairly stated in all material respects in relation to the financial
statements taken as a whole.

                 BOK Financial Thrift Plan for Hourly Employees

                          Notes to Financial Statements

                                December 31, 2003


1. Description of Plan

The following description of the BOK Financial Thrift Plan for Hourly Employees
(the Plan) provides only general information. Participants should refer to the
Summary Plan Description or the Plan document for a more complete description of
the Plan's provisions.

General

The Plan is a defined contribution plan covering all employees of BOK Financial
Corporation (BOKF) and its subsidiaries and affiliates (collectively, the
Employer or Company) who have attained age 21 and one year of service
(equivalent to 1,000 hours) and who are compensated on an hourly basis, except
those covered under a collective bargaining agreement and those treated as
independent contractors. Effective April 1, 2003, an eligible employee may enter
the Plan monthly following the date the employee is credited with one full month
of service. Additionally, as of April 1, 2003, all new eligible employees are
automatically enrolled in the Plan at a three percent contribution rate unless
the employee designates on the enrollment form not to participate. The Plan is
subject to the provisions of the Employee Retirement Income Security Act of 1974
(ERISA).

Contributions

Participants may elect to contribute up to 100 percent of their compensation (as
defined by the Plan) on a pre-tax basis pursuant to a salary reduction agreement
filed with the Plan administrator. In addition, participants may make after-tax
contributions which shall not exceed 5 percent of each participant's
compensation, however, the combination of pre-tax and after-tax contributions
cannot be more than 100% of compensation (as defined by the plan). Participants
may elect investment in any of ten mutual funds, self-directed common stocks or
registered investment companies, and BOKF Common Stock.

The Employer contributes a matching contribution to the Plan. The matching
contribution may be made in cash or in shares of BOKF Common Stock. In 2003, the
entire matching contribution of $25,332 was made in cash.

                 BOK Financial Thrift Plan for Hourly Employees

                    Notes to Financial Statements (continued)


1. Description of Plan (continued)

For 2003, the Employer matching contribution ranges from $.40 to $1.00 for each
dollar of the participant's contribution, up to five percent of compensation,
based on each participant's years of service as follows:

               Years of Service                         Matching Percentage
-------------------------------------------------- ----------------------------

Less than four years                                              40%
At least four, but less than ten years                            60%
At least ten, but less than fifteen years                         80%
Fifteen or more years                                            100%

The Employer may in its sole discretion, make an additional discretionary
contribution to the Plan. There was no discretionary contribution in 2003.

Participant Accounts

Each participant's account is credited with the participant's contribution and
allocations of (a) the Employer's contribution and (b) Plan earnings.
Allocations are based on participant earnings or account balances, as defined by
the Plan. The benefit to which a participant is entitled is the benefit that can
be provided from the participant's vested account.

Vesting

Participants vest in Employer matching contributions based upon years of
service, as defined by the Plan. Participants are 100 percent vested upon
completion of five years of service and are immediately vested in their deferred
(pre-tax) contributions, after-tax contributions, and the actual earnings
thereon.

Loans

Participants may borrow against their accounts in amounts not less than $1,000
and not to exceed the lesser of $50,000 or 50 percent of the participant's
vested account balance. Loans will bear interest based on the current banking
prime rate when the loan is requested and may not exceed a five-year term,
unless it is used to acquire the primary residence of the participant, in which
case the maximum term may be 25 years. The loans are secured by the balance in
the participant's account. Interest rates range from 4.00 percent to 9.50
percent. Repayment is made by payroll withholdings.

Payment of Benefits

A participant who terminates employment with a vested account balance less than
$5,000, excluding rollover contributions, will receive a lump-sum payment. If
the participant has a vested balance which exceeds $5,000, excluding rollover
contributions, the Plan will make a distribution only with the consent of the
participant at any time prior to the earlier of the participant's 65th birthday
or death. In lieu of a lump-sum payment, a participant who terminates employment
after his or her 65th birthday or after attaining age 60 and completing 10 years
of service, shall be entitled to elect monthly, quarterly, semi-annual or annual
installment payments to be paid over a period not to exceed 10 years from the
benefit commencement date. The installments may be accelerated at the direction
of the participant.

 6

1. Description of Plan (continued)

Forfeitures

Forfeited balances of terminated participants' nonvested accounts are utilized
to pay administrative costs or to reduce future Employer contributions. During
2003, forfeitures of $1,855 were used to reduce Employer matching contributions.

Plan Termination

The Employer expects to continue the Plan indefinitely. However, the Employer
reserves the right to discontinue the Plan or to amend the Plan, in whole or in
part, from time-to-time. In the event of Plan termination, participants will
become 100 percent vested in their accounts.

2. Summary of Significant Accounting Policies

Basis of Accounting

The financial statements of the Plan are prepared on the accrual basis of
accounting.

Administrative Expenses

The Employer pays all administrative expenses of the Plan, except for loan
origination fees, which are paid by the participants.

 7

2. Summary of Significant Accounting Policies (continued)

Investment Valuation and Income Recognition

Shares of registered investment companies are valued at published market prices
which represent the net asset value of shares held by the Plan at year-end. The
BOKF Common Stock is valued at the quoted market price. Participant loans
receivable are valued at cost which approximates fair value.

Purchases and sales of securities are recorded on a trade-date basis. Dividend
income is recorded on the ex-dividend date. Interest income is recorded on the
accrual basis.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally
accepted accounting principles requires management to make estimates that affect
the amounts reported in the financial statements and accompanying notes. Actual
results could differ from those estimates.

3. Investments

The Plan's investments are held by a bank administered trust fund at Bank of
Oklahoma, N.A. Trust Division (the Trustee). During 2003, the Plan's investments
(including investments purchased and sold, as well as held during the year)
appreciated in fair value as determined by quoted market prices for BOKF Common
Stock and published market prices for registered investment companies as
follows:

                                                      Net Appreciation
                                                        in Fair Value
                                                       of Investments
                                                 ----------------------------

   BOK Financial Corporation Common Stock              $    17,797
   Registered investment companies                          30,652
                                                 ----------------------------
                                                       $    48,449
                                                 ============================

The fair value of individual investments that represent five percent or more of
the Plan's net assets are separately identified in the financial statements.

 8

4. Income Tax Status

The Plan has received a determination letter from the Internal Revenue Service
dated April 1, 2002, stating that the Plan is qualified under Section 401 of the
Internal Revenue Code (the Code) and, therefore, the related trust is exempt
from taxation. Subsequent to this issuance of the determination letter, the Plan
was amended. Once qualified, the Plan is required to operate in conformity with
the Code to maintain its qualification. The Plan administrator believes the Plan
is being operated in compliance with the applicable requirements of the Code and
therefore, believes that the Plan is qualified and the related trust is tax
exempt.

5. Reconciliation of Financial Statements to the Form 5500

The following is a reconciliation of net assets available for benefits per the
