Summary of Performance

BOK Financial Corporation ("BOK Financial") recorded net income of $45.5 million
or $0.68 per diluted common share for the second quarter of 2004 compared with
$40.8 million or $0.61 per diluted common share for the same period of 2003.
Prior year earnings per share have been restated for a 3% dividend paid in
common shares on May 31, 2004. The annualized returns on average assets and
equity were 1.32% and 14.36% for the quarter ended June 30, 2004 compared to
returns of 1.29% and 14.06% for the second quarter of 2003. The increase in
return on average equity between the two quarters resulted primarily from net
income growth. Average shareholders' equity increased $112 million to $1.3
billion due to retained earnings being partially offset by a $48 million
decrease in average accumulated other comprehensive income, which is a component
of shareholders' equity.

Net income increased $4.8 million or 12% due primarily to a $7.3 million
increase in net interest revenue and a $5.5 million decrease in provision for
loan losses. Net interest revenue increased 7% due primarily to earning asset
growth. The provision for loan losses decreased due primarily to a continued
decline in net charge-offs. Additionally, fees and commission revenue grew $2.1
million or 3%, primarily due to increased deposit, trust and transaction card
fees. This growth in fee revenue was largely offset by a 55% reduction in
mortgage banking revenue. Securities losses during the second quarter of 2004
totaled $11.0 million. Substantially all of these losses were incurred on
securities held as economic hedges of mortgage servicing rights ("MSRs") and
were largely offset by a $10.9 million recovery in the fair value of the MSRs.
Securities losses, net of recovery of MSR fair values totaled $752 thousand for
the second quarter of 2004. Net securities gains less MSR provision totaled $7.1
million for the second quarter of 2003. Operating expenses, excluding the MSR
provision, increased $976 thousand compared with the second quarter last year.

Year-to-date net income totaled $84.7 million for 2004 compared with $84.2
million for 2003. Diluted earnings per share were $1.27 for both years. Net
interest revenue grew $14.6 million or 8% due primarily to a $963 million
increase in average earning assets, partially offset by a decrease in net
interest margin. The provision for loan losses for the first half of 2004
totaled $11.0 million; $8.4 million lower than the first half of 2003. Fees and
commissions increased $5.9 million or 4%. Double digit percentage growth in
deposit fees, trust and transaction card revenues were partially offset by a 52%
reduction in mortgage banking revenue. Securities losses of $6.7 million were
recognized during the first six months of 2004. These losses, which primarily
resulted from securities held as economic hedges of the MSR portfolio, were
offset by a $7.2 million recovery in the fair value of MSRs. During the first
half of 2003, net

3

gains of $12.1 million from the combined effects of securities used to hedge the
risk of MSRs and the increase in fair value of the servicing rights were
recognized. Net gains on sales of securities not designated for the MSR hedging
program totaled $12.5 million for the first half of 2003. Operating expenses
increased $6.5 million or 3%, excluding the MSR provision.


Net Interest Revenue

Tax-equivalent net interest revenue totaled $106.3 million for the second
quarter of 2004 compared to $99.3 million for the same period of 2003. The
increase in net interest revenue was due to an $873 million increase in average
earning assets, partially offset by a 2 basis point decrease in net interest
margin. The growth in average earning assets included a $577 million increase in
outstanding loan balances and a $293 million increase in securities. The growth
in average earning assets was funded by a $411 million increase in average
interest-bearing deposits and a $547 million increase in average
noninterest-bearing demand deposits. The growth in interest-bearing deposits
consisted primarily of a $336 million increase in transaction deposit accounts.
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 second quarter of 2004 compared to the second quarter of
2003. The net interest margin, the ratio of tax-equivalent net interest revenue
to average earning assets, declined to 3.46% from 3.48% 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
loan portfolio decreased 22 basis points and the yield on the securities
portfolio decreased 11 basis points compared to the previous year. Average
loans, net of reserves, comprised 60% of average earning assets for the second
quarters of 2004 and 2003. The remaining average earning assets consisted of
securities. The cost of interest-bearing liabilities decreased 12 basis points
for the same periods. Growth in non-interest bearing funding sources, primarily
demand deposit accounts and capital, increased the net interest margin by 2
basis points. The effects of declining interest rates on asset yields and cost
of funds for the past five quarters are presented in the Quarterly Financial
Summary.

Tax-equivalent net interest revenue for the first six months of 2004 increased
$14.2 million or 7% compared with last year. This increase was also due to
growth in average earning assets, partially offset by a decrease in net interest
margin. Average earning assets increased $963 million or 9%, including a $561
million increase in average outstanding loan balances and a $415 million
increase in securities. The growth in average earning assets was funded by a
$576 million increase in average interest-bearing liabilities and a $449 million
increase in average noninterest-bearing demand deposit accounts. The net
interest margin decreased 7 basis points to 3.46%. Yields on average earning
assets fell 28 basis points while the cost of interest-bearing liabilities
decreased 20 basis points.

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. This strategy
also helps manage overall interest rate risk. Interest rates on these borrowed
funds, which generally react quickly to changes in market interest rates, tend
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 second quarter of 2004, this strategy enhanced net
interest revenue $14.3 million, compared with $15.1 million for the second
quarter of 2003. Excluding this strategy, net interest margin was 3.52% and
3.56% for the second quarters of 2004 and 2003. The average balance of
securities purchased and funds borrowed under this strategy was $1.8 billion. 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 second quarter of 2004 decreased $18.0 million
compared with the second quarter of 2003 due to a $21.5 million reduction in net
gains from securities sales. Fees and commissions increased $2.1 million or 3%
and continue to represent a significant portion of total revenue. Fees and
commissions represented 43% of total revenue, excluding gains and losses on
securities and derivatives, in the second quarter of 2004. This is compared with
44% for the same period of 2003. Colorado State Bank and Trust ("CSBT"), which
was acquired in the third quarter of 2003, contributed $2.2 million to the
increase in fees and commissions revenue, including $1.8 million of trust fees.
In total, trust fees and commissions grew $3.1 million or 29%. The fair value of
trust assets increased 33% to $23 billion compared to a year ago, including $4.1
billion due to value appreciation and new business and $1.6 billion from the
CSBT acquisition. Service charges on deposit accounts increased $4.3 million or
22% and transaction card revenue increased $2.8 million or 20%. Deposit service
charges increased due to continued growth in overdraft fees. The growth in
transaction card revenue reflected increased ATM processing volume. Mortgage
banking revenue decreased $9.1 million or 55% due to an $8.0 million decrease in
secondary marketing gains related to the lower volume of loans funded and a $1.1
million decrease in mortgage servicing revenue related to a 14% reduction in the
outstanding balance

5

of loans serviced for others. The reduction in mortgage banking revenue is more
fully discussed in the Lines of Business - Mortgage Banking section of this
report.

BOK Financial recognized net securities losses of $11.0 million during the
second quarter of 2004 compared with net gains of $10.5 million during the
second quarter of 2003. Net losses on securities designated as an economic hedge
of the mortgage servicing portfolio totaled $10.1 million in 2004, including
$4.4 million from other than temporary impairment. Certain securities, which
were purchased during the first quarter of 2004, declined in value due to
increased market interest rates. Management determined that it did not intend to
hold these securities long enough for the impairment to reverse. This impairment
was partially realized through a sale of securities subsequent to June 30, 2004.
Net gains on securities designated as an economic hedge of the mortgage
servicing portfolio totaled $4.4 million in 2003.

BOK Financial also recognized net losses of $892 thousand during the second
quarter of 2004 from sales of securities not used to hedge MSRs, compared with
net gains of $6.1 million during the second quarter of 2003. Strategies utilized
during the second quarter of 2004 were to maintain the size of the securities
portfolio at approximately $4.7 billion and to continue management of extension
risk. Approximately $253 million of proceeds were generated from securities
sales during the second quarter and $372 million was received from maturities. A
total of $668 million was invested in the securities portfolio during the
quarter. Management estimated that the average life of the securities portfolio
was approximately 3.4 years, up from 2.5 years for the second quarter of 2003
and 3.0 years for the first quarter of 2004. At June 30, 2004, BOK Financial
held available for sale securities with a net unrealized loss of $75 million, or
2% of the total fair value of available for sale securities, caused by recent
increases in market interest rates. These unrealized losses are considered
temporary based upon the company's ability and management's intent to hold the
securities until the value recovers.

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

Fees and commissions revenue for the first six months of 2004 increased $5.9
million or 4% compared to the same period of 2003. CSBT contributed $4.2 million
to fees and commissions revenue in 2004, including $3.3 million of trust fees.
Total trust, deposit and transaction card fees increased 32%, 19% and 18%,
respectively. Service charges on deposit accounts increased due to growth in
overdraft fees, and transaction card fees increased due to increased processing
volumes. Mortgage banking revenue decreased 52% due to reductions in loan
origination and refinancing activities and servicing fee revenue. Net losses on
securities totaled $6.7 million for the first half of 2004, including losses of
$7.9 million on securities designated as economic hedges of MSRs. Net gains on
securities totaled $20.1 million for the first half of 2003, including gains of
$7.6 million from MSR hedge securities.

Other Operating Expense

Other operating expense for the quarter ended June 30, 2004 totaled $99.0
million, a $13.2 million decrease compared to the second quarter of 2003.
Operating expenses in 2004 were reduced by $10.9 million from the recovery in
fair value of MSRs. A provision for impairment of MSRs increased operating
expenses by $3.4 million in the second quarter of 2003. Excluding the provision
for MSR impairment, operating expenses for the second quarter of 2004 increased
$976 thousand or 1% compared with the same period in 2003. Operating expenses
for the second quarter of 2004 included $4.8 million for CSBT. Mortgage banking
costs, which consisted primarily of MSR amortization expense, decreased $7.0
million. Variations in mortgage banking costs are more fully discussed in the
Lines of Business - Mortgage Banking section of this report.

Personnel expense increased $6.2 million or 12% compared with the second quarter
of 2003, including $2.8 million related to CSBT. The remaining increase in
personnel expense of $3.4 million was due primarily to growth in incentive
compensation. Including CSBT, average regular compensation per full-time
equivalent employee ("FTE") increased 3% and the number of FTE increased by 41.
Employee benefit costs, which totaled $9.6 million, increased 4% compared to
last year.

Data processing and communications costs increased $2.3 million or 18%. This
increase was due primarily to a $1.0 million increase related to transaction
card processing volumes, $493 thousand due to increased amortization expense and
$250 thousand from CSBT.

Operating expenses for the first six months of 2004 increased $3.7 million or 2%
compared with the same period of 2003. Excluding the provision for mortgage
servicing rights, operating expenses increased $6.4 million or 3%. Operating
expenses for CSBT totaled $4.8 million and we recognized $4.1 million for the
cost of appreciated securities contributed to the BOK Charitable Foundation.
Personnel expenses increased $10.7 million or 10%, including $5.3 million from
CSBT. The remaining increase in personnel costs was primarily due to increased
incentive compensation. Data processing expenses increased 22% to $29.9 million
due to the same factors that affected the second quarter. Mortgage banking costs
decreased $15.6 million or 60% due to lower amortization of mortgage servicing
rights.

Income Taxes

Income tax expense totaled $25.9 million for the second quarter of 2004 and
$46.3 million for the first half of 2004. These amounts represent 36% and 35%,
respectively, of pre-tax book income. Income tax expense for the first half of
2004 reflected the benefit of contributing appreciated securities to the BOk
Charitable Foundation during the first quarter of the year. Excluding this
benefit, income tax expense for the first half of 2004 would have been $47.5
million or 36% of pre-tax book 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 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. Over the past
year, the average transfer-pricing rate for these deposit accounts decreased.

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 throughout Oklahoma and surrounding
states. 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 $16.8 million or 37% to consolidated net income for
the second quarter of 2004. This contribution to net income compares with $14.0
million or 34% of consolidated net income for the second quarter of 2003. Other
operating revenue increased $2.7 million or 13% due primarily due to a $2.0
million increase in revenue from TransFund. Operating expenses increased $2.7
million to $25.0 million for the second quarter of 2004 from $22.3 million for
the same period of the prior year. The increase in operating expenses included
$1.2 million 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's retail brokerage division. The Consumer Banking Division
contributed $3.3 million or 7% to consolidated net income for the second
quarter of 2004. This compares to $2.1 million or 5% of consolidated net income
for the second quarter of 2003. Other operating revenue increased $2.4 million
or 21% over the second quarter of 2003 due primarily to deposit account service
charges.

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 $9.1 million or 55%
compared to the second quarter of 2003. Mortgage servicing revenue fell by $1.1
million due to a 14% decrease in the principal balance of loans serviced for
others. Secondary marketing gains decreased $8.0 million as the volume of loans
funded fell. The decrease in mortgage banking revenue reduced Mortgage Banking's
contribution to consolidated net income to $2.2 million or 5% for the second
quarter of 2004 compared with $5.6 million or 14% for the same period of 2003.

BOK Mortgage comprises two sectors, loan production and loan servicing. The loan
production sector generally performs best over a period of decreasing mortgage
interest rates when loan origination volumes are high. Conversely, the loan
servicing sector generally performs best when mortgage interest rates are
relatively stable or increasing and prepayments are low. Rising interest rates,
which began in the second half of 2003, significantly reduced the volume of loan
applications and funding, which has substantially reduced loan production
revenue. However, rising mortgage interest rates have increased the value of
mortgage servicing rights and reduced related amortization expense.

Loan Production Sector

Pre-tax income from loan production decreased to $2.5 million for the second
quarter of 2004 compared to $11.6 million for the previous year's second
quarter. Operating revenue from loan production was $4.3 million in the second
quarter of 2004, including $3.6 million of capitalized mortgage servicing
rights, compared to revenue from loan production of $12.1 million in the second
quarter of 2003, including $7.1 million of capitalized mortgage servicing
rights. Mortgage loans funded totaled $197 million in the second quarter of 2004
compared to $400 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 37% of loans funded
during the second quarter of 2004 were for refinanced loans compared to 69% for
the second quarter of 2003. The pipeline of mortgage loan applications totaled
$232 million at June 30, 2004, down from $300 million at the end of the
preceding quarter.

Loan Servicing Sector

The loan servicing sector earned a pre-tax profit of $307 thousand for the
second quarter of 2004 compared to a pre-tax loss of $2.8 million for the same
period of 2003. Rising interest rates during the second quarter of 2004
increased the fair value of the MSRs and required a $10.9 million reduction in
the valuation allowance. The reversal of this allowance was partially offset by
$10.1 million of losses on securities designated as economic hedges. During the
second quarter of 2003, the fair value of MSRs declined due to falling interest
rates. The decline in fair value required a $3.4 million impairment provision
which was offset by realized gains of $4.4 million on securities held as an
economic hedge of the MSRs.

Amortization expense, which is based on both actual and anticipated loan
prepayments, decreased to $3.8 million in the second quarter of 2004 compared to
$10.1 million in the same period of 2003 due to rising interest rates and a
reduction in loan prepayment speeds relative to a year ago.

Servicing revenue totaled $4.5 million in 2004 compared to $5.6 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 was $4.2 billion for the second quarter of 2004 compared to $4.9
billion for the second quarter of 2003. The decrease in loans serviced reflected
both the rapid refinancing of mortgage loans and a decision to curtail purchases
of mortgage loan servicing.

The valuation allowance for impairment of mortgage servicing rights totaled $12
million at June 30, 2004 compared to $50 million at June 30, 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

10

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 $2.7
million write-down of mortgage servicing rights against the valuation allowance
was recorded during the second 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 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 June 30, 2004, assets with a fair value of $32 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. 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. 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 $1.9 million or 4% to consolidated net income for
the second quarter of 2004 compared to $2.7 million or 7% last year. Operating
revenue grew $1.1 million or 5% compared with the same quarter of 2003. The
growth in operating revenue came primarily from trust fees and commissions. At
June 30, 2004, the wealth management line of business was responsible for trust
assets with aggregate market values of $20.9 billion under various fiduciary
arrangements, compared to $16.9 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 $7.6 billion of
trust assets at June 30, 2004 compared to $7.0 billion at June 30, 2003.
Operating expenses increased $3.1 million or 15%, including $1.3 million for the
cost to restructure an incentive compensation agreement.

Regional Banks

Regional banks include Bank of Texas, Bank of Albuquerque, Bank of Arkansas, and
Colorado State Bank and Trust. Each of these banks provides a full range of
corporate and consumer banking services in their respective markets. Small
businesses and middle-market corporations are the regional banks' primary
customer focus. Regional banks contributed $12.2 million or 27% to consolidated
net income for the second quarter of 2004. This compares to $10.6 million or 26%
of consolidated net income for the second quarter of 2003.

Operations in Texas, New Mexico, Arkansas and Colorado contributed $8.3 million,
$3.2 million, $673 thousand and $41 thousand, respectively, to consolidated net
income for the second quarter of 2004. This is compared with $6.9 million, $2.6
million, $625 thousand and $426 thousand, respectively, for the second quarter
of 2003. Net income from operations in Texas increased $1.4 million or 20%
compared with the second quarter of 2003. Net interest revenue increased $5.2
million or 14% due primarily to an 18% increase in average assets. The increase
in net interest revenue was partially offset by a $1.0 million increase in net
loans charged off. Net income from operations in New Mexico increased $578
thousand or 22% due primarily to an $880 thousand increase in fees and
commissions revenue.

Discussion and Analysis of Operations

Loans

The aggregate loan portfolio at June 30, 2004 totaled $7.5 billion and increased
$25 million during the quarter. Residential mortgage loans, including loans held
for sale, increased $43 million and commercial loans increased $14 million.
These were partially offset by a $30 million reduction in outstanding commercial
real estate loans.

Outstanding loans to energy customers totaled $1.1 billion or 14% of total loans
at June 30, 2004. Approximately $918 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 $28 million or 3% during the
second quarter as continued high energy prices provided cash flow to the
industry. Outstanding loans to the services industry totaled $1.5 billion at
June 30, 2004. Loans to the services industries now comprise 20% of the total
loan portfolio. Services included loans that totaled $271 million to nursing
homes and $134 million to the healthcare industry. The remainder of the services
sector of the loan portfolio is comprised of a large number of loans to small
and medium-sized businesses with no notable concentrations. Agriculture loans,
which increased $4 million during the quarter, included $200 million of loans to
the cattle industry. Other notable loan concentrations by primary industry of
the borrowers are presented in Table 10.

Commercial real estate loans totaled $1.6 billion at June 30, 2004 or 21% of the
total loan portfolio. Construction and land development loans decreased $14
million. Construction and land development loans included $286 million for
single-family residential lots and premises. Multifamily real estate loans
decreased $8 million or 3% due primarily to one large payoff and limited loan
funding during the quarter. The major components of other commercial real estate
loans were office buildings at $288 million and retail facilities at $310
million.

Residential mortgage loans, excluding loans held for sale, included $401 million
of home equity loans, $298 million of loans held for business relationship, $231
million of adjustable rate mortgage loans and $133 million of loans held for

14

community development. Consumer loans included $209 million of indirect
automobile loans. Substantially all of these loans were purchased from dealers
in Oklahoma. Approximately 13% 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 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 Financial. Offsetting contracts are
executed between BOK Financial and selected counterparties to minimize the risk
to BOK Financial of changes in energy prices, interest rates or foreign

15

exchange rates. The counterparty contracts are identical to the customer
contracts, except for a fixed pricing spread or fee paid to BOK Financial as
compensation for administrative costs, credit risk and profit.

These programs create credit risk for amounts due to BOK Financial 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 June 30, 2004, the fair value
of derivative contracts reported as assets under these programs totaled $294
million. This included energy contracts with fair values of $285 million and
foreign exchange contracts with fair values of $7 million. The aggregate fair
values of offsetting liability contracts totaled $296 million. Approximately 64%
of the fair value of asset contracts was with customers. The remaining 36% was
with counterparties. Conversely, approximately 65% of the fair value of
liability contracts was with counterparties. The remaining 35% was due to
various customers. The maximum exposure to any single customer or counterparty
totaled $38 million at June 30, 2004.

Summary of Loan Loss Experience

The reserve for loan losses, which is available to absorb losses inherent in the
loan portfolio, totaled $129 million at June 30, 2004 compared to $130 million
at March 31, 2004 and $123 million at June 30, 2003. These amounts represent
1.73%, 1.75%, and 1.78%, 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 224% of
nonperforming loans at June 30, 2004, compared with 280% at March 31, 2004 and
221% at June 30, 2003. Net loans charged off during the second quarter totaled
$4.9 million, compared to $5.8 million in the first quarter of 2004 and $6.4
million the second quarter of 2003. 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 June 30, 2004, specific impairment
reserves totaled $3.7 million on total impaired loans of $48 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 June 30, 2004, the
range of potential losses for the more significant factors were:

General economic conditions $ 6.6 million - $ 10.4 million
Concentration of large loans $ 1.6 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 $62 million at June
30, 2004, $52 million at March 31, 2004 and $61 million at June 30, 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 increased $11.2 million during the second quarter of 2004. Newly
identified nonaccruing loans totaled $22.7 million. Two loans in unrelated
industries comprised $15.9 million of the newly identified nonaccruing loans.
This increase in nonaccruing loans was partially offset by $4.6 million from
cash payments received and $2.1 million from charge-offs and foreclosure.
Nonaccruing loans also decreased $4.6 million due to a loan returned to accruing
status after a period of satisfactory performance.

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

17

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 $60 million at June 30, 2004 compared to $69
million at March 31, 2004 and $57 million at June 30, 2003. At June 30, 2004,
the composition of potential problem loans by primary industry categories
included services industries - $17 million, energy and related services - $11
million, healthcare - $10 million and manufacturing - $7 million.

Deposits

Total deposits increased $245 million to $9.6 billion during the second quarter
of 2004. Deposit growth came primarily from time deposits, which increased $243
million. Brokered time deposits increased $194 million to $437 million at June
30, 2004. The increase in brokered deposits was the result of a strategy to
lower brokered deposit funding costs without affecting liquidity. Existing
shorter-term brokered deposits were replaced with longer-term fixed-rate
brokered deposits. The longer-term deposits have more standardized terms and can
be hedged more effectively with interest rate swaps, which are used to convert
the cost of the funds to a LIBOR-based floating rate. A discussion of the
hedging of the brokered time deposits with interest rate swaps is included in
the Market Risk section of this report.

Average core deposits, which we define as deposits of less than $100,000
excluding public funds and brokered time deposits, increased $199 million or 4%
compared to the first quarter of 2004. Public funds decreased $10 million or 1%
during this same period due to the timing of tax receipts. Average brokered
deposits increased $94 million or 38%. The remaining deposits, which were
comprised of account balances in excess of $100,000, increased $80 million or
2%.

The distribution of deposit accounts among BOK Financial's principal markets is
shown in Table 14. Total deposits grew by 2% and 3%, respectively, in the
Oklahoma and Texas markets, and 5% in New Mexico during the second quarter.

Capital

Shareholders' equity decreased $37 million during the second quarter of 2004 and
totaled $1.3 billion at June 30, 2004. Net income for the quarter of $45.5
million was offset by an $83 million decrease in accumulated other comprehensive
income. The decrease in accumulated other comprehensive income resulted from
depreciation in the fair value of BOK Financial's portfolio of available for
sale securities due to rising interest rates. This decrease in accumulated other
comprehensive income is considered temporary based upon the company's ability
and management's intent to hold the securities until the value recovers.

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 1, 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 210,069 after adjustment for the 3% dividend
paid in common shares in the second quarter of 2004. 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 $39.27, its closing price on June 30, 2004

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 3.0 years
while the related funds borrowed have an average duration of 90 days. Securities
purchased and funds borrowed under this strategy averaged $1.8 billion during
the second quarter of 2004.

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 second quarters of 2004 and 2003, net interest
revenue increased $3.7 million and $4.0 million, respectively, from periodic
settlements of these contracts.

Interest rate derivatives with notional amounts of $472 million have been
designated as fair value hedges of fixed-rate brokered certificates of deposit
and debt. During the second quarter of 2004, the fair values of these
derivatives decreased $7.3 million. The corresponding fair values of the hedged
liabilities increased $7.8 million during this same period. The net effect of
these changes in fair values, combined with changes in fair value of interest
rate derivatives not designated as hedges for accounting purposes, resulted in a
net gain of $201 thousand in the second quarter of 2004. This is compared with a
net loss of $1.1 million in the second quarter of 2003 from adjustments of
interest rate swaps to fair value. No interest rate derivatives were designated
as hedges in the prior year. 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 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.

The decrease in economic value of equity assuming a 200 basis point rate shock
was due primarily to projected decreases in the fair values of securities of
$325 million and fixed-rate loans of $125 million. A 200 basis point rate shock
is estimated to extend the duration of the securities portfolio by less than one
year. The decrease in fair value of securities and loans would be partially
offset by an estimated $384 million increase in the fair values of fixed rate
deposits and other borrowed funds.

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,

22

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 exceptions.

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 June 30, 2004, the VAR was $223 thousand. The
greatest value at risk during the second quarter of 2004 was $793 thousand.


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.
