Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations

Results of Operations

Summary of Performance

BOK Financial Corporation ("BOK Financial") recorded net income of $39.2 million
or $0.60 per diluted common share for the first quarter of 2004 compared to
$43.5 million or $0.67 per diluted common share for the same period of 2003. The
annualized returns on average assets and equity were 1.16% and 12.59% for the
quarter ended March 31, 2004 compared to returns of 1.43% and 15.80% for the
first quarter of 2003. The decrease in return on average equity between the two
quarters resulted from lower net income and a 12% increase in average
shareholders' equity, which is consistent with the company's strategy of
retaining earnings to support asset growth.

The $4.3 million or 10% decrease in net income was due primarily to a $3.3
million decrease in net after-tax gains on sales of securities and
mark-to-market of derivative contracts and the $1.4 million after-tax cost of
appreciated securities contributed to the BOk Charitable Foundation. In addition
to these changes, net interest revenue increased $7.3 million or 8% due
primarily to earning asset growth. The provision for loan losses decreased $2.9
million due to improvement in credit quality indicators. Fees and commission
revenue grew $3.7 million or 5%, primarily due to increased trust, deposit and
transaction card fees. This growth in fee revenue was partially offset by a 50%
reduction in mortgage banking revenue. Operating expenses, excluding the cost of
securities contributed to the BOk Charitable Foundation, increased $12.8 million
due primarily to higher personnel and data processing costs.

Net Interest Revenue

Tax-equivalent net interest revenue totaled $104.0 million for the first quarter
of 2004 compared to $96.9 million for the same period of 2003. The increase in
net interest revenue was due to a $962 million increase in average earning
assets, partially offset by a 12 basis point decrease in net interest margin.
The growth in average earning assets included a $445 million increase in
securities and a $533 million increase in net loans. The growth in average
earning assets was funded by a $738 million increase in average interest-bearing
liabilities and a $352 million increase in average noninterest-bearing demand
deposits. The growth in interest-bearing liabilities included $531 million in
transaction deposit accounts and $255 million in funds purchased. Table 1
reflects the effects on net interest revenue of changes in average balances and
interest rates for the various types of earning assets and interest-bearing
liabilities.

Yields on average earning assets and rates paid on interest-bearing liabilities
both declined in the first quarter of 2004 compared to the first quarter of
2003. The net interest margin, the ratio of tax-equivalent net interest revenue
to average earning assets, declined to 3.45% from 3.57% for the same period of
2003. The decrease in net interest margin was due to yields on earning assets
falling more than rates paid on interest-bearing liabilities. The yield on the
securities portfolio decreased 46 basis points and the yield on the loan
portfolio decreased 35 basis points compared to the previous year. The mix of
earning assets remained constant at 39% securities and 60% loans for both the
first quarter of 2004 and 2003. The cost of interest-bearing liabilities
decreased 28 basis points for the same periods. The effects of declining
interest rates on asset yields and rates paid for the past five quarters are
presented in the Quarterly Financial Summary.

BOK Financial follows a strategy of fully utilizing its capital resources by
borrowing funds in the capital markets to supplement deposit growth. The
proceeds of these borrowed funds are invested in securities. The primary
objective of this strategy is to enhance revenue opportunities. In the current
market conditions, this strategy also helps manage our overall interest rate
risk. The interest rate on these borrowed funds, which generally reacts quickly
to changes in market interest rates, tends to match the effect of changes in
interest rates on the loan portfolio. Interest rates earned on the securities
purchased with the proceeds of these borrowed funds are affected less quickly by
changes in market interest rates. The timing of changes in interest rates earned
on securities more closely matches the timing of changes in interest rates paid
on deposits. Although this strategy may reduce net interest margin, it provides
positive net interest revenue. We estimate that for the first quarter of 2004,
this strategy enhanced net interest revenue $14.9 million, compared to $13.6
million for the first quarter of 2003. Excluding this strategy, net interest
margin for the first quarter of 2004 was 3.51% compared to 3.62% for the first
quarter of 2003. Average securities purchased and funds borrowed under this
strategy were $1.9 billion in first quarter of 2004 and 2003. As more fully
discussed in the Market Risk section of this report, we employ various
techniques to manage, within certain parameters, the interest rate and liquidity
risks inherent in this strategy. The effectiveness of these techniques is
reflected in the overall change in net interest revenue due to changes in
interest rates as shown in Table 17.

Other Operating Revenue

Other operating revenue for the first quarter of 2004 decreased $1.4 million or
2% compared to the first quarter of 2003. Fees and commissions increased $3.7
million or 5% and continue to represent a significant portion of total revenue.
Fees and commissions represented 42% of total revenue, excluding gains and
losses on securities and derivatives, in the first quarter of 2004. This is
compared to 43% for the same period of 2003. Trust fees and commissions grew
$3.5 million or 35% due to increased fair value of assets managed and the
acquisition of Colorado State Bank and Trust ("CSBT") during 2003. The fair
value of trust assets increased 24% to $21 billion compared to a year ago,
including $2.6 billion due to value appreciation and new business and $1.6
billion from the CSBT acquisition. Service charges on deposit accounts increased
$3.2 million or 17% and transaction card revenue increased $2.0 million or 16%.
The growth in transaction card revenue was due to increased volume. Mortgage
banking revenue decreased $7.8 million or 50%. The causes of this decrease are
more fully discussed in the Lines of Business - Mortgage Banking section of this
report.

BOK Financial realized net gains on securities sales of $4.3 million during the
first quarter of 2004 compared to net gains of $9.7 million during the first
quarter of 2003. These amounts included net gains from sales of securities
designated as an economic hedge of the mortgage servicing portfolio of $2.2
million in 2004 compared to net gains of $3.2 million in 2003. The remaining net
gains on sales of securities, which resulted from total return management of the
securities portfolio, were $2.1 million in 2004 compared to net gains of $6.5
million in 2003. The expected duration of the securities portfolio at March 31,
2004 was 3 years, approximately the same as December 31, 2003 and within
established guidelines. Our strategies during the first quarter of 2004 were to
increase the size of the securities portfolio by approximately $200 million and
to continue management of extension risk. Approximately $1.2 billion of sales
proceeds were generated from securities sales during the first quarter and $212
million was received from maturities. A total of $1.6 billion was invested in
the securities portfolio during the quarter.

Net losses on derivatives primarily represent the mark to market of the
derivative portfolio used for interest rate risk management. Additional
discussion regarding BOK Financial's use of derivative instruments is located in
the Market Risk section of this report.

Other Operating Expense

Other operating expense for the quarter ended March 31, 2004 totaled $116.0
million, a $16.9 million increase compared to the first quarter of 2003.
Operating expenses in 2004 included a $4.1 million contribution of appreciated
securities to the BOk Charitable Foundation. Operating expenses increased $12.8
million or 13% excluding this contribution.

 5

Personnel expense increased $4.4 million or 8% compared to the first quarter of
2003. This increase included $2.6 million from CSBT and $1.6 million from
executive deferred compensation plans. The cost of these plans varies with
changes in the value of BOK Financial common stock, which increased $2.28 or 6%
per share during the first quarter of 2004. Additionally, the cost of these
plans may vary with changes in performance measured against pre-defined targets.
Excluding the effects of the CBST acquisition and the deferred compensation
plans, personnel expense increased $214 thousand to $54.0 million. Regular
compensation expense increased $835 thousand or 2% to $34.7 million. Average
regular compensation per full time equivalent employee ("FTE") increased 6%
while the number of FTE decreased by 108. Incentive compensation, which totaled
$10.3 million, decreased $238 thousand from last year. Employee benefit costs
decreased $396 thousand or 4% to $9.0 million.

Data processing costs increased $2.9 million or 25% due primarily to $1.1
million of expenses related to higher transaction card, trust and deposit
processing volumes. Amortization expense from our new core data processing
system implemented in the fourth quarter of 2003 contributed $566 thousand to
the increase in data processing expense.

Mortgage banking expenses, including the provision for impairment of mortgage
servicing rights, increased $2.9 million compared with the first quarter of
2003. Variations in these expenses, which are both affected by changes in
interest rates, are more fully discussed in the Lines of Business section of
this report.

Income Taxes

Income tax expense totaled $20.4 million or 34% of book taxable income for the
first quarter of 2004 compared to $24.2 million or 36% for the same period of
2003. The reduction in income tax expense as a percent of book taxable income
for 2004 reflected the benefit of contributing appreciated securities to the BOk
Charitable Foundation. Excluding this benefit, income tax expense would have
been $21.6 million or 36% of book taxable income.

Lines of Business

BOK Financial operates four principal lines of business under its Bank of
Oklahoma ("BOk") franchise: corporate banking, consumer banking, mortgage
banking and wealth management. It also operates a fifth principal line of
business, regional banks, which includes all banking functions for Bank of
Albuquerque, N.A., Bank of Arkansas, N.A., Bank of Texas, N.A., and Colorado
State Bank and Trust, N.A. In addition to its lines of business, BOK Financial
has a funds management unit. The primary purpose of this unit is to manage the
overall liquidity needs and

 6

interest rate risk of the company. Each line of business borrows funds from and
provides funds to the funds management unit as needed to support their
operations.

BOK Financial allocates resources and evaluates performance of its lines of
business after allocation of funds, certain indirect expenses, taxes and capital
costs. The cost of funds borrowed from the funds management unit by the
operating lines of business is transfer priced at rates that approximate market
for funds with similar duration. Market is generally based on the applicable
LIBOR or interest rate swap rates, adjusted for prepayment risk. This method of
transfer-pricing funds that support assets of the operating lines of business
tends to insulate them from interest rate risk.

The value of funds provided by the operating lines of business to the funds
management unit is based on applicable Federal Home Loan Bank advance rates.
Deposit accounts with indeterminate maturities, such as demand deposit accounts
and interest-bearing transaction accounts, are transfer-priced at a rolling
average based on expected duration of the accounts. The expected duration ranges
from 90 days for certain rate-sensitive deposits to five years. Economic capital
is assigned to the business units based on an allocation method that reflects
management's assessment of risk. Management uses a third-party developed capital
allocation model. This model assigns capital based upon credit, operating,
interest rate and market risk inherent in our business lines and recognizes the
diversification benefits among the units. The level of assigned economic capital
is a combination of the risk taken by each business line, based on its actual
exposures and calibrated to its own loss history where possible. Additional
capital is assigned to the regional banks line of business based on BOK
Financial's investment in those entities.

Corporate Banking

The Corporate Banking Division provides loan and lease financing and treasury
and cash management services to businesses principally in Oklahoma. In addition
to serving the banking needs of small businesses, middle market and larger
customers, the Corporate Banking Division has specialized groups that serve
customers in the energy, agriculture, healthcare and banking/finance industries
and includes the TransFund ATM network. The Corporate Banking Division
contributed $16.2 million or 41% to consolidated net income for the first
quarter of 2004. This compares to $14.1 million or 32% of consolidated net
income for the first quarter of 2003. Net interest revenue increased $2.2
million or 8% due primarily to a 7% increase in average assets. Other operating
revenue increased $3.1 million or 17% due primarily to a $1.8 million increase
in TransFund revenue. Operating expenses increased to $23.0 million for the
first quarter of 2004 from $21.0 million for the same period of the prior year
primarily due to a $1.4 million increase in TransFund transaction processing
costs.

Consumer Banking

The Consumer Banking Division provides a full line of deposit, loan and
fee-based services to customers throughout Oklahoma through four major
distribution channels: traditional branches, supermarket branches, the 24-hour
ExpressBank call center and Online Banking. Additionally, the division is a
significant referral source for the Bank of Oklahoma Mortgage Division ("BOk
Mortgage") and BOSC, Inc.'s retail brokerage division. BOSC, Inc. is a full
service broker/dealer subsidiary of BOK Financial. The Consumer Banking Division
contributed $2.3 million or 6% to consolidated net income for the first quarter
of 2004. This compares to $1.9 million or 4% of consolidated net income for the
first quarter of 2003. Other operating revenue increased $1.8 million, or 16%
over the first quarter of 2003 due primarily to increases in deposit service
charges. Operating expenses increased $1.8 million or 11% due primarily to
growth in personnel costs.

Mortgage Banking

BOK Financial engages in mortgage banking activities through BOk Mortgage. These
activities include the origination, marketing and servicing of conventional and
government-sponsored mortgage loans. Consolidated mortgage banking revenue,
which is included in other operating revenue, decreased $7.8 million or 50%
compared to the first quarter of 2003. Mortgage servicing revenue fell by $1.4
million due to an 18% decrease in the principal balance of loans serviced for
others. Secondary marketing gains decreased $6.4 million as the volume of loans
funded fell.

BOK Mortgage is comprised of two sectors, loan production and loan servicing.
The loan production sector generally performs best when mortgage interest rates
are low and loan origination volumes are high. Conversely, the loan servicing
sector generally performs best when mortgage interest rates are relatively high
and prepayments are low. A sharp increase in interest rates in mid-2003 from
historic lows significantly reduced the volume of loan applications in
subsequent quarters. This resulted in lower loan production revenue during the
first quarter. Additionally, interest rates decreased slightly during the first
quarter of 2004, which required a provision for impairment of mortgage servicing
rights.

Loan Production Sector

Pre-tax income from loan production decreased to $1.9 million for the first
quarter of 2004 compared to $10.8 million for the previous year's first quarter.
Operating revenue from loan production was $3.9 million in the first quarter of
2004, including $3.2 million of capitalized mortgage servicing rights, compared
to revenue from loan production of $11.1 million in the first quarter of 2003,
including $5.5 million of capitalized mortgage servicing rights. Mortgage loans
funded totaled $160 million in the first quarter of 2004 compared to $331
million during the same period last year. The decrease in loan production
revenue and volume of loans funded reflected the effects of higher interest
rates on refinancing activities. Approximately 43% of loans funded during the
first quarter of 2004 were for refinanced loans compared to 74% for the first
quarter of 2003. The pipeline of mortgage loan applications totaled $300 million
at

 8

March 31, 2004, compared to $208 million at the end of the preceding quarter.

Loan Servicing Sector

The loan servicing sector incurred a pre-tax loss of $2.5 million for the first
quarter of 2004 compared to pre-tax income of $4.1 million for the same period
of 2003. This change in pre-tax operating results was due primarily to the
effects of falling interest rates during the first quarter of 2004, which
required a provision for impairment of mortgage servicing rights of $3.7
million. This provision was partially offset by gains on sales of securities
designated as an economic hedge which totaled $2.2 million. During the first
quarter of 2003, rising interest rates resulted in a $7.8 million partial
recovery of the provision for impairment of mortgage servicing rights. We also
recognized gains of $3.2 million from sales of securities designated as an
economic hedge. Changes in interest rates also affected amortization expense,
which is based on both actual and anticipated loan prepayments. Amortization
expense decreased to $5.2 million in 2004 compared to $13.1 million in 2003 due
to rising interest rates and a reduction in loan prepayment speeds relative to a
year ago.

Servicing revenue totaled $4.8 million in 2004 compared to $6.1 million in 2003.
The decrease in servicing revenue was due primarily to a lower outstanding
principal balance of loans serviced. The average outstanding balance of loans
serviced, including loans serviced for BOk, was $4.7 billion for the first
quarter of 2004 compared to $5.6 billion for the first quarter of 2003. The
decrease in loans serviced reflected both the rapid refinancing of mortgage
loans and our decision to curtail purchases of mortgage loan servicing.

The valuation allowance for impairment of mortgage servicing rights totaled $26
million at March 31, 2004 compared to $47 million at March 31, 2003 and $32
million at December 31, 2003. A valuation allowance is provided to reduce the
carrying value of servicing rights to the lower of fair value or amortized cost
segregated by impairment strata. Impairment strata are determined by interest
rate bands and by loan types, either conventional or government-backed. The fair
value of servicing rights is based on estimated revenues that will be generated
over the servicing period, less estimated costs to service the loans. The
valuation allowance may be reversed, in part or in whole, if the fair value of
servicing rights in a particular impairment strata increase or if the amortized
cost of servicing rights in a particular strata decrease. Fair value may
increase if anticipated loan prepayment speeds decrease. Amortized cost of a
particular impairment stratum will decrease through amortization. We
periodically review the various impairment strata to determine whether the
values of the impaired servicing rights are likely to recover. When it becomes
probable that the impairment is other than temporary based on an estimate of
fair values over a range of interest rates and prepayment speeds, a permanent
impairment write-down of the servicing rights is charged against the valuation
allowance. A $10.1 million write-down of mortgage servicing rights against the
valuation allowance was recorded during the first quarter of 2004.

BOK Financial designates a portion of its securities portfolio as an economic
hedge against the risk of loss on its mortgage servicing rights. Mortgage-backed
securities and U.S. government agency debentures are acquired and held as
available for sale when prepayment risks exceed certain levels. We may also use
"to be announced" ("TBA") securities as part of our economic hedging strategy.
These TBA securities are considered derivative instruments. Because the fair
values of these securities and derivatives are expected to vary inversely to the
fair value of the servicing rights, they are expected to offset risk. No special
hedge accounting treatment is applicable to either the mortgage servicing rights
or the assets designated as an economic hedge. Changes in fair value of
available for sale securities are recognized in shareholders' equity, net of
taxes, and changes in the fair value of TBA securities are recognized in income.

This hedging strategy presents certain risks. A well-developed market determines
the fair value for securities and related derivatives. However, there is no
comparable market for mortgage servicing rights. Therefore, the computed change
in value of the servicing rights for a specified change in interest rates may
not correlate to the change in value of the securities.

At March 31, 2004, assets with a fair value of $220 million were held for the
economic hedge program. The interest rate sensitivity of the mortgage servicing
rights and assets held as a hedge is modeled over a range of +/- 50 basis
points. Additionally, the estimated effect of a +100 basis point change in
interest rates is presented due to the rise in interest rates that has occurred
subsequent to March 31, 2004. At March 31, 2004, the pre-tax results of this
modeling on reported earnings were:

Wealth Management

BOK Financial provides a wide range of financial services through its wealth
management line of business, including trust and private financial services and
brokerage and trading activities. This line of business includes the activities
of BOSC, Inc., a registered broker/dealer. Trust and private financial services
include sales of institutional, investment and retirement products, loans and
other services to affluent individuals, businesses, not-for-profit
organizations, and governmental agencies. Trust services are primarily provided
to clients in Oklahoma, Texas, Arkansas and New Mexico. Trust services provided
through Colorado State Bank and Trust are included in the regional banking line
of business. Additionally, trust services include a nationally competitive,
self-directed 401-(k) program. Brokerage and trading activities within the
wealth management line of business consist of retail sales of mutual funds,
securities and annuities, institutional sales of securities and derivatives,
bond underwriting and other financial advisory services.

Wealth management contributed $2.9 million or 7% to consolidated net income for
the first quarter of 2004 compared to $2.3 million or 5% in the first quarter of
last year. The increase was due primarily to growth in trust fees, which
increased $2.0 million or 19%. At March 31, 2004, the wealth management line of
business was responsible for trust assets with aggregate market values of $19
billion under various fiduciary arrangements, compared to $16 billion a year
ago. The growth in trust assets reflected increased market value of assets
managed in addition to new business generated. We have sole or joint
discretionary authority over $7.7 billion of trust assets at March 31, 2004
compared to $6.7 billion at March 31, 2003.

loans held for sale, increased $44 million. This was partially offset by a $17
million reduction in outstanding commercial loans and an $11 million decrease in
commercial real estate loans.

Outstanding loans to energy customers totaled $1.1 billion or 15% of total loans
at March 31, 2004. Approximately $916 million of the energy loan portfolio was
to oil and gas producers. The amount of credit available to these customers
generally depends on the value of their proven energy reserves based on current
prices. The energy loan category also included loans to borrowers involved in
the transportation of oil and gas and loans to borrowers that manufacture
equipment and provide other services to the energy industry. The aggregate
outstanding balance of energy loans decreased $124 million or 10% during the
first quarter as currently high prices for oil and natural gas provided cash
flow to the industry. This included a decrease of $76 million in our Oklahoma
markets, $38 million in Texas and $10 million in Colorado. Outstanding loans to
the services industry totaled $1.4 billion at March 31, 2004. Services included
loans that totaled $257 million to nursing homes and $136 million to the
healthcare industry. Agriculture loans, which were unchanged during the quarter,
included $187 million of loans to the cattle industry. Outstanding loans to the
wholesale/retail sector of the portfolio increased $49 million or 7%. Loans to
the manufacturing sector increased $19 million or 4% with growth noted in all
markets. Other notable loan concentrations by primary industry of the borrowers
are presented in Table 10.

Commercial real estate loans totaled $1.6 billion at March 31, 2004 or 22% of
the total loan portfolio. Construction and land development loans increased $15
million. Construction and land development loans included $292 million for
single-family residential lots and premises. Multifamily real estate loans
decreased $18 million or 7% due primarily to a $22 million reduction in
multifamily loans in Texas. The major components of other commercial real estate
loans were office buildings - $306 million and retail facilities - $299 million.

Residential mortgage loans, excluding loans held for sale, included $377 million
of home equity loans, $277 million of loans held for business relationship, $231
million of adjustable rate mortgage loans and $133 million of loans held for

 12

community development. Consumer loans included $209 million of indirect
automobile loans. Substantially all of these loans were purchased from dealers
in Oklahoma. Approximately 14% of the indirect automobile loan portfolio was
considered sub-prime.

While BOK Financial continued to increase geographic diversification through
expansion into Texas, New Mexico and Colorado, geographic concentration subjects
the loan portfolio to the general economic conditions in Oklahoma. Table 11
presents the distribution of the major loan categories among BOK Financial's
principal market areas.

Other Derivatives with Credit Risk

BOK Financial offers a program that permits its customers to hedge various
risks. Much of the focus of these programs had been on assisting energy
producing customers to hedge against price fluctuations and to take positions
through energy derivative contracts. We have added or expanded programs to
assist customers in managing their interest rate and foreign exchange risks
during 2003. Each of these programs work essentially the same way. Derivative
contracts are executed between the customers and BOk. Offsetting contracts are
executed between BOk and selected

 13

counterparties to minimize the risk to us of changes in energy prices, interest
rates or foreign exchange rates. The counterparty contracts are identical to the
customer contracts, except for a fixed pricing spread or fee paid to BOk as
compensation for administrative costs, credit risk and profit.

These programs create credit risk for amounts due to BOk from its customers and
counterparties. Customer and counterparty credit risks are monitored through
existing policies. Margin collateral may be required from customers and
counterparties based on assessment of credit risk.

A deterioration of the credit standing of one or more counterparties may result
in BOK Financial recognizing a loss as the fair value of the affected contracts
may no longer move in tandem with the offsetting contracts. This could occur if
the credit standing of a counterparty deteriorated such that either the fair
value of energy production no longer supported the contract or the
counterparty's ability to provide margin collateral was impaired.

Derivative contracts are carried at fair value. At March 31, 2004, the fair
value derivative contracts reported as assets under these programs totaled $221
million. This included energy contracts with fair values of $216 million and
foreign exchange contracts with fair values of $5 million. The aggregate fair
values of offsetting liability contracts totaled $223 million. Approximately 65%
of the fair value of asset contracts was with customers. The remaining 35% was
with counterparties. Conversely, approximately 69% of the fair value of
liability contracts was with counterparties. The remaining 31% was due to
various customers. The maximum exposure to any single customer or counterparty
totaled $33 million.

Summary of Loan Loss Experience

The reserve for loan losses, which is available to absorb losses inherent in the
loan portfolio, totaled $130 million at March 31, 2004 compared to $129 million
at December 31, 2003 and $120 million at March 31, 2003. These amounts represent
1.75%, 1.73% and 1.75%, respectively, of total loans, excluding loans held for
sale. Losses on loans held for sale, principally mortgage loans accumulated for
placement in security pools, are charged to earnings through adjustments in the
carrying value. The reserve for loan losses also represented 280% of
nonperforming loans at March 31, 2004, up from 244% at December 31, 2003 and
236% at March 31, 2003. Net loans charged-off during the first quarter totaled
$5.8 million, compared to $6.3 million in the fourth quarter of 2003 and $6.3
million in the first quarter of 2003. Based on credit quality indicators, the
provision for loan losses was reduced from $9.9 million in the first quarter of
2003 to $7.0 million in the first quarter of 2004. Table 12 presents statistical
information regarding the reserve for loan losses.

Specific reserves for impairment are determined through evaluation of estimated
future cash flows and collateral value. At March 31, 2004, specific impairment
reserves totaled $3.7 million on total impaired loans of $40 million.

Nonspecific reserves are maintained for risks beyond factors specific to an
individual loan or those identified through migration analysis. A range of
potential losses is determined for each factor identified. At March 31, 2004 the
range of potential losses for the more significant factors was:

General economic conditions         $ 6.4 million    - $  9.3 million
Concentration of large loans        $ 1.5 million    - $  3.1  million

Evaluation of the loan loss reserve requires a significant level of assumptions
by management including estimation of future cash flows, collateral values,
relevance of historical loss trends to the loan portfolio and assessment of
current economic conditions on the borrowers' ability to repay. The required
loan loss reserve could be materially affected by changes in these assumptions.
The loan loss reserve is adequate to absorb losses inherent in the loan
portfolio based upon current conditions and information available to management.
However, actual losses may differ significantly due to changing conditions or
information that is not currently available.

Nonperforming Assets

Information regarding nonperforming assets, which totaled $52 million at March
31, 2004, $60 million at December 31, 2003 and $56 million at March 31, 2003 is
presented in Table 13. Nonperforming assets included nonaccrual loans and
excluded loans 90 days or more past due but still accruing interest. Nonaccrual
loans decreased $6.3 million during the first quarter of 2004, including $9.2
million from cash payments received and $3.4 million from charge-offs and
foreclosure. This decrease was partially offset by newly identified nonaccruing
loans of $7.8 million.

The loan review process also identifies loans that possess more than the normal
amount of risk due to deterioration in the financial condition of the borrower
or value of the collateral. Because the borrowers are still performing in
accordance with the original terms of the loan agreements and no loss of
principal or interest is anticipated, these loans are not included in
nonperforming assets. Known information does, however, cause management to have
concerns as to the borrowers' ability to comply with current repayment terms.
Potential problem loans totaled $69 million at March 31, 2004 compared to $56
million at December 31, 2003 and $56 million at March 31, 2003. At March 31,
2004 the

 15

composition of potential problem loans by primary industry categories included
energy and related services - $24 million, healthcare - $10 million and
manufacturing - $10 million.

Deposits

Total deposits increased $146 million to $9.4 billion during the first quarter
of 2004. Demand deposits increased $273 million to $1.9 billion. This increase
was partially offset by a $183 million decrease in interest-bearing transaction
accounts. Core deposits which we define as deposits of less than $100,000
excluding public funds and broker deposits, decreased $78 million or 2%. Public
funds increased $122 million or 20% during the quarter due to the timing of tax
receipts for municipalities and school districts. Brokered deposits decreased
$30 million to $243 million at March 31, 2004. The remaining deposits, which
were comprised of account balances in excess of $100,000 increased $102 million
or 3% during the quarter.

The distribution of deposit accounts among BOK Financial's principal markets is
shown in Table 14. Total deposits grew by $152 million or 2% during the first
quarter primarily in the Oklahoma and Texas markets. This growth was partially
offset by a $23 million decrease in deposits in Northwest Arkansas due primarily
to a decrease in large time deposits.

Capital

Shareholders' equity increased $67 million during the first quarter of 2004 and
totaled $1.3 billion at March 31, 2004. The increase was primarily due to net
income for the quarter and a $27 million increase in accumulated other
comprehensive income. The increase in accumulated other comprehensive income
resulted from appreciation in the fair value of BOK Financial's portfolio of
available for sale securities.

BOK Financial and its subsidiary banks are subject to various capital
requirements administered by the federal banking agencies. Failure to meet
minimum capital requirements can result in certain mandatory and additional
discretionary actions by regulators that could have a material effect on
operations. These capital requirements include quantitative measures of assets,
liabilities and certain off-balance sheet items. The capital standards are also
subject to qualitative judgments by the regulatory agencies about components,
risk weightings and other factors. For a banking institution to qualify as well
capitalized, as defined by the banking agencies, its Tier I, Total and Leverage
capital ratios must be at least 6%, 10% and 5%, respectively. BOK Financial's
capital ratios are presented in Table 15. Additionally, each subsidiary bank
exceeds the regulatory definition of well capitalized.

During 2002, BOK Financial issued shares of common stock for its purchase of
Bank of Tanglewood. In addition, BOK Financial agreed to a limited price
guarantee on a portion of the shares issued in this purchase. Pursuant to this
guarantee, any holder of BOK Financial common shares issued in this acquisition
may annually make a claim for the excess of the guaranteed price and the actual
sales price of any shares sold during a 60-day period after each of the first
five anniversary dates after October 25, 2002. The maximum annual number of
shares subject to this guarantee is 203,951. BOK Financial may elect, in its
sole discretion, to issue additional shares of common stock to satisfy any
obligation under the price guarantee or to pay cash.

The following table presents the estimated number of common shares that would be
required to be issued and the cash value equivalent if the market value of BOK
Financial's common stock remained at $41.00, its closing price on March 31,

Quantitative and Qualitative Disclosures about Market Risk

Market risk is a broad term for the risk of economic loss due to adverse changes
in the fair value of a financial instrument. These changes may be the result of
various factors, including interest rates, foreign exchange prices, commodity
prices or equity prices. Financial instruments that are subject to market risk
can be classified either as held for trading or held for purposes other than
trading.

BOK Financial is subject to market risk primarily through the effect of changes
in interest rates on both its assets held for purposes other than trading and
trading assets. The effects of other changes, such as foreign exchange rates,
commodity prices or equity prices do not pose significant market risk to BOK
Financial. BOK Financial has no material investments in assets that are affected
by changes in foreign exchange rates or equity prices. Energy derivative
contracts, which are affected by changes in commodity prices, are matched
against offsetting contracts as previously discussed.

Responsibility for managing market risk rests with the Asset / Liability
Committee that operates under policy guidelines established by the Board of
Directors. The acceptable negative variation in net interest revenue, net income
or economic value of equity due to a specified basis point increase or decrease
in interest rates is generally limited by these guidelines to +/- 10%. These
guidelines also set maximum levels for short-term borrowings, short-term assets,
public funds, and brokered deposits, and establish minimum levels for unpledged
assets, among other things. Compliance with these guidelines is reviewed
monthly.

Interest Rate Risk - Other than Trading

BOK Financial has a large portion of its earning assets in variable rate loans
and a large portion of its liabilities in demand deposit accounts and
interest-bearing transaction accounts. Changes in interest rates affect earning
assets more rapidly than interest-bearing liabilities in the short term.
Management has adopted several strategies to reduce this interest rate
sensitivity. As previously noted in the Net Interest Revenue section of this
report, management acquires securities that are funded by borrowings in the
capital markets. These securities have an expected average duration of 3 years
while the related funds borrowed have an average duration of 90 days. Securities
purchased and funds borrowed under this strategy averaged $1.9 billion during
the first quarter of 2004.

Additionally, BOK Financial uses interest rate swaps in managing its interest
rate sensitivity. These products are generally used to more closely match
interest on certain loans with funding sources and long-term certificates of
deposit with earning assets. During the first quarters of 2004 and 2003, net
interest revenue increased $2.4 million and $3.3 million, respectively, from
periodic settlements of these contracts. Additionally, a net loss of $995
thousand was recognized in the first quarter of 2004 compared to a net loss of
$1.3 million in the first quarter of 2003 from adjustments of interest rate
swaps to fair value. Credit risk from these swaps is closely monitored.
Derivative contracts are not used for speculative purposes.

The effectiveness of these strategies in managing the overall interest rate risk
is evaluated through the use of an asset/liability model. BOK Financial performs
a sensitivity analysis to identify more dynamic interest rate risk exposures,
including embedded option positions, on net interest revenue, net income and
economic value of equity. A

 19

simulation model is used to estimate the effect of changes in interest rates
over the next twelve months based on eight interest rate scenarios. Three
specified interest rate scenarios are used to evaluate interest rate risk
against policy guidelines. These are a "most likely" rate scenario and two
"shock test" scenarios, first assuming a sustained parallel 200 basis point
increase and second assuming a sustained parallel 100 basis point decrease in
interest rates. Management historically evaluated interest rate sensitivity for
a sustained 200 basis point decrease in rates. However, these results are not
meaningful in the current low-rate environment. An independent source is used to
determine the most likely interest rate scenario.

BOK Financial's primary interest rate exposures included the Federal Funds rate,
which affects short-term borrowings, and the prime lending rate and the London
Interbank Offering Rate, which are the basis for much of the variable-rate loan
pricing. Additionally, mortgage rates directly affect the prepayment speeds for
mortgage-backed securities and mortgage servicing rights. Derivative financial
instruments and other financial instruments used for purposes other than trading
are included in this simulation. The model incorporates assumptions regarding
the effects of changes in interest rates and account balances on indeterminable
maturity deposits based on a combination of historical analysis and expected
behavior. The impact of planned growth and new business activities is factored
into the simulation model. The effects of changes in interest rates on the value
of mortgage servicing rights are excluded from Table 17 due to the extreme
volatility over such a large rate range. The effects of interest rate changes on
the value of mortgage servicing rights and securities identified as economic
hedges are presented in the Lines of Business - Mortgage Banking section of this
report.

The simulations used to manage market risk are based on numerous assumptions
regarding the effects of changes in interest rates on the timing and extent of
repricing characteristics, future cash flows and customer behavior. These
assumptions are inherently uncertain and, as a result, the model cannot
precisely estimate net interest revenue, net income or economic value of equity
or precisely predict the impact of higher or lower interest rates on net
interest revenue, net income or economic value of equity. Actual results will
differ from simulated results due to timing, magnitude and frequency of interest
rate changes, market conditions and management strategies, among other factors.

Trading Activities

BOK Financial enters into trading activities both as an intermediary for
customers and for its own account. As an intermediary, BOK Financial will take
positions in securities, generally mortgage-backed securities, government agency
securities, and municipal bonds. These securities are purchased for resale to
customers, which include individuals, corporations, foundations and financial
institutions. BOK Financial will also take trading positions in U.S. Treasury
securities, mortgage-backed securities, municipal bonds and financial futures
for its own account. These positions are taken with the objective of generating
trading profits. Both of these activities involve interest rate risk.

A variety of methods are used to manage the interest rate risk of trading
activities. These methods include daily marking of all positions to market
value, independent verification of inventory pricing, and position limits for
each trading activity. Hedges in either the futures or cash markets may be used
to reduce the risk associated with some trading programs. The Risk Management
Department monitors trading activity daily and reports to senior management and
the Risk Oversight and Audit Committee of the BOK Financial Board of Directors
any exceptions to trading position limits and risk management policy.

 20

BOK Financial uses a Value at Risk ("VAR") methodology to measure the market
risk inherent in its trading activities. VAR is calculated based upon historical
simulations over the past five years using a variance / covariance matrix of
interest rate changes. It represents an amount of market loss that is likely to
be exceeded only one out of every 100 two-week periods. Trading positions are
managed within guidelines approved by the Board of Directors. These guidelines
limit the VAR to $1.6 million. At March 31, 2004, the VAR was $865 thousand. The
greatest value at risk during the first quarter of 2004 was $1.3 million.

Controls and Procedures

As required by Rule 13a-15(b), BOK Financial's management, including the Chief
Executive Officer and Chief Financial Officer, conducted an evaluation as of the
end of the period covered by their report, of the effectiveness of the company's
disclosure controls and procedures as defined in Exchange Act Rule 13a-15(e).
Based on that evaluation, the Chief Executive Officer and Chief Financial
Officer concluded that the disclosure controls and procedures were effective as
of the end of the period covered by this report. As required by Rule 13a-15(d),
BOK Financial's management, including the Chief Executive Officer and Chief
Financial Officer, also conducted an evaluation of the company's internal
controls over financial reporting to determine whether any changes occurred
during the quarter covered by this report that have materially affected, or are
reasonably likely to materially affect, the company's internal controls over
financial reporting. Based on that evaluation, there has been no such change
during the quarter covered by this report.

Forward-Looking Statements

This report contains forward-looking statements that are based on management's
beliefs, assumptions, current expectations, estimates, and projections about BOK
Financial, the financial services industry and the economy in general. Words
such as "anticipates," "believes," "estimates," "expects," "forecasts," "plans,"
"projects," variations of such words and similar expressions are intended to
identify such forward-looking statements. Management judgments relating to and
discussion of the provision and reserve for loan losses involve judgments as to
expected events and are inherently forward-looking statements. Assessments that
BOK Financial's acquisitions and other growth endeavors will be profitable are
necessary statements of belief as to the outcome of future events, based in part
on information provided by others that BOK Financial has not independently
verified. These statements are not guarantees of future performance and involve
certain risks, uncertainties and assumptions that are difficult to predict with
regard to timing, extent, likelihood and degree of occurrence. Therefore, actual
results and outcomes may materially differ from what is expressed, implied, or
forecasted in such forward-looking statements. Internal and external factors
that might cause such a difference include, but are not limited to: (1) the
ability to fully realize expected cost savings from mergers within the expected
time frames, (2) the ability of other companies on which BOK Financial relies to
provide goods and services in a timely and accurate manner, (3) changes in
interest rates and interest rate relationships, (4) demand for products and
services, (5) the degree of competition by traditional and nontraditional
competitors, (6) changes in banking regulations, tax laws, prices, levies, and
assessments, (7) the impact of technological advances and (8) trends in customer
behavior as well as their ability to repay loans. BOK Financial and its
affiliates undertake no obligation to update, amend, or clarify forward-looking
statements, whether as a result of new information, future events or otherwise.

Report of Management on Consolidated Financial Statements

Management is responsible for the unaudited consolidated financial statements,
which have been prepared in accordance with accounting principles generally
accepted in the United States and all related information in this report. In
management's opinion, the accompanying unaudited consolidated financial
statements contain all adjustments (consisting of normal recurring accruals)
necessary to present fairly the financial conditions, results of operations and
cash flows of BOK Financial and its subsidiaries at the dates and for the
periods presented.

BOK Financial and its subsidiaries maintain a system of internal accounting
controls designed to provide reasonable assurance that transactions are executed
in accordance with management's general or specific authorization, and are
recorded as necessary to maintain accountability for assets and to permit
preparation of financial statements in accordance with accounting principles
generally accepted in the United States. This system includes written policies
and procedures, a corporate code of conduct, an internal audit program and
standards for the hiring and training of qualified personnel.

The Board of Directors of BOK Financial maintains a Risk Oversight and Audit
Committee consisting of outside directors that meet periodically with management
and BOK Financial's internal and independent auditors. The Committee considers
the audit and nonaudit services to be performed by the independent auditors,
makes arrangements for the internal and independent audits and recommends BOK
Financial's selection of independent auditors. The Committee also reviews the
results of the internal and independent audits, critical accounting policies and
practices, and various shareholder reports and other reports and filings.

The financial information included in this interim report has been prepared by
management without audit by independent public accountants and should be read in
conjunction with BOK Financial's 2003 Form 10-K filed with the Securities and
Exchange Commission which contains audited financial statements.

(5) Shareholders' Equity

On April 27, 2004, the Board of Directors of BOK Financial declared a 3% stock
dividend payable in shares of BOK Financial common stock. The dividend is
payable on or about May 31, 2004 to shareholders of record on May 10, 2004.
Generally accepted accounting principles require earnings per share information
to be retroactively restated to reflect the new capital structure upon
consummation of a stock dividend. Accordingly, for all financial statements
issued after May 31, 2004, earnings per share will be restated as follows:

Diluted Earnings Per Share:
                                     As Reported        Restated

(8)  Contingent Liabilities

In the ordinary course of business, BOK Financial and its subsidiaries are
subject to legal actions and complaints. Management believes, based upon the
opinion of counsel, that the actions and liability or loss, if any, resulting
from the final outcomes of the proceedings, will not be material in the
aggregate.

(9) Financial Instruments with Off-Balance Sheet Risk

BOK Financial is a party to financial instruments with off-balance-sheet risk in
the normal course of business to meet the financing needs of its customers and
to manage interest rate risk. Those financial instruments involve, to varying
degrees, elements of credit risk in excess of the amount recognized in BOK
Financial's Consolidated Balance Sheets. Exposure to credit loss in the event of
nonperformance by the other party to the financial instrument for commitments to
extend credit and standby letters of credit is represented by the notional
amount of those instruments.

As of March 31, 2004, outstanding commitments and letters of credit were as
follows (in thousands):
