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

Performance Summary

BOK Financial Corporation ("BOKF" or the "Company") reported net income of $52.1
million, or $0.78 per diluted share for the first quarter of 2005, compared with
$39.2 million, or $0.59 per diluted share for the first quarter of 2004. The
annualized returns on average assets and shareholders' equity were 1.45% and
14.96%, respectively, for the first quarter of 2005, compared with returns of
1.16% and 12.59%, respectively, for the first quarter of 2004. The increase in
net income was attributed to growth in net interest revenue, reduction in the
provision for credit losses and appreciation in the value of mortgage servicing
rights.

Net interest revenue increased $4.4 million or 4% over 2004 due primarily to
loan growth. Average outstanding loan balances for the first quarter of 2005
increased $468 million compared with the same period of 2004. Net interest
revenue for the first quarter of 2005 also included $1.3 million from the
collection of foregone interest on a non-performing loan and a large loan fee.
The provision for credit losses decreased $5.0 million compared to the same
period in 2004 as credit quality continued to improve. The fair value of
mortgage servicing rights appreciated due to a 40 basis point increase in
mortgage interest rates. The increase in the fair value of servicing rights, net
of gains or losses recognized on financial instruments held as an economic
hedge, resulted in a $3.5 million increase in pre-tax income for the first
quarter of 2005 compared with a $1.5 million decrease in pre-tax income for the
same period of 2004.

Results of Operations

Net Interest Revenue

Tax-equivalent net interest revenue totaled $108.9 million for the first quarter
of 2005 compared with $104.4 million for 2004. The increase was due primarily to
a $555 million increase in average earning assets. The growth in average earning
assets included a $468 million, or 6%, increase in loans and a $57 million
increase in securities. Growth in average earning assets was funded primarily by
a $361 million increase in interest-bearing liabilities and a $252 million, or
15%, increase in demand deposit accounts. In addition, net interest revenue for
the first quarter of 2005 included $605 thousand from the collection of foregone
interest on a non-performing loan and a $650 thousand fee on a large commercial
loan that paid off during the quarter. These two collections increased net
interest margin for the quarter by 4 basis points. Table 1 shows 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.

Net interest margin, the ratio of tax-equivalent net interest revenue to average
earning assets was 3.46% for the first quarter of 2005, unchanged from the first
quarter of 2004 and up from 3.38% for the fourth quarter of 2004. Yields on
average earning assets continued to trend upwards due to the effect of rising
interest rates. The yield on average earning assets was 5.46%, up 57 basis
points compared with the first quarter of 2004 and 31 basis points over the
fourth quarter of 2004. The yield on average loans was 6.06%, an increase of 86
basis points over the first quarter of 2004 and 44 basis points over the fourth
quarter of 2004. The tax-equivalent yield on securities was 4.36% for the first
quarter of 2005, compared with 4.29% for the first quarter of 2004 and 4.30% for
the fourth quarter of 2004. Rates paid on average interest-bearing liabilities
during the first quarter of 2005 increased 70 basis points over the first
quarter of 2004 and 27 basis points over the fourth quarter of 2004. Increases
in rates paid on deposit accounts continued to lag behind the increases in loan
yields. Additionally, growth in non-interest bearing funding sources, primarily
demand deposits, increased the net interest margin 13 basis points compared with
the first quarter of 2004 and four basis points compared to the preceding
quarter.

Our overall objective is to manage the Company's balance sheet to be essentially
neutral to changes in interest rates. Approximately 73% of our commercial loan
portfolio is either variable rate or fixed rate that will reprice within one
year. These loans are funded primarily by deposit accounts that are either
non-interest bearing, or that reprice more slowly than the loans. The result is
a balance sheet that is asset sensitive, which means that assets generally
reprice more quickly than liabilities. Strategies we use to achieve a
rate-neutral position include the purchase of fixed-rate, mortgage-backed
securities funded by short-term borrowings. The average duration of these
securities is expected to be approximately 3.2 years based on a range of
interest rate and prepayment assumptions. The funds borrowed to purchase these
securities generally reprice within 90 days. The liability-sensitive nature of
this strategy provides an offset to the asset-sensitive characteristics of our
loan portfolio.

We also use derivative instruments to manage our interest rate risk. We have
interest rate swaps with a combined notional amount of $472 million that convert
fixed rate liabilities to floating rate based on LIBOR. These derivatives, which
generally have been designated as fair value hedges, reduce the asset-sensitive
nature of our balance sheet. We also have interest rate swaps with a notional
amount of $100 million that convert prime-based loans to fixed rate. These
derivatives, which have been designated as cash flow hedges, also reduce the
asset-sensitive nature of our balance sheet.

The effectiveness of these strategies is reflected in the overall change in net
interest revenue due to changes in interest rates as shown in Table 1 and in the
interest rate sensitivity projections as shown in Market Risk section of this
report.

Other Operating Revenue

Other operating revenue decreased $1.7 million compared with the first quarter
of 2004 due to a $5.1 million decrease in net gains and losses on securities and
derivatives. Fees and commissions revenue, which is included in other operating
revenue, increased $3.2 million or 4%. Diversified sources of fees and
commissions revenue are a significant part of our business strategy and
represented 42% of total revenue, excluding gains and losses on securities and
derivatives, for both the first quarters of 2005 and 2004. We believe that a
variety of fee revenue sources provide an offset to changes in interest rates,
values in the equity markets, commodity prices and consumer spending, all of
which can be volatile. We anticipate growth in other operating revenue through
offering new products and services and by expanding into new markets. However,
increased competition and saturation in our existing markets could affect the
rate of future increases.

Fees and commissions revenue

Trust fees increased $2.3 million, or 17%, for the first quarter of 2005. The
fair value of all trust assets, which is the basis for a significant portion of
trust fees, increased to $25.4 billion at March 31, 2005 compared with $21.3
billion at March 31, 2004. The increase in trust assets included $195 million
from a change in the valuation method for oil and gas properties. Regulatory
authorities have directed all banks to report oil and gas properties at
estimated fair value. Previously, a nominal value was assigned to these assets.
Trust revenue will not be affected by this change. Trust fees from mutual fund
activities increased $955 thousand or 40% due primarily to increased fees
associated with our assumption of administration duties for the American
Performance Funds.

Brokerage and trading revenue increased $1.3 million, or 13%. Revenue from
securities trading activities increased $796 thousand, or 13%. Customer hedging
revenue increased 44% to $1.2 million. Volatility in the energy markets prompted
our energy customers to more actively hedge their gas and oil production.

Transaction card revenue increased $1.8 million, or 12%, due to growth in check
card revenue and ATM fees. Revenue growth from each of these activities was due
to growth in transaction volume.

Service charges on deposit accounts were unchanged compared with the first
quarter of 2004. Overdraft fees, which had been a consistent source of increased
fee income, grew 4%, or $517 thousand. The volume of overdraft items processed
has declined, which is consistent with an apparent trend in the industry.
Commercial account service charge revenue decreased $615 thousand, or 7%. This
reduction in fee revenue reflected the increase in earnings credit available to
commercial deposit customers as interest rates rise.

Mortgage banking revenue, which is discussed more fully in the Line of Business
- - Mortgage Banking section of this report decreased $2.2 million, or 28%,
compared with the first quarter of 2004. Net gains on mortgage loans sold
decreased $1.7 million due primarily to a decrease in sales volume. Servicing
revenue decreased $513 thousand due to a decrease in the average outstanding
balance of loans serviced.

Securities and derivatives

BOK Financial realized net losses of $1.9 million on securities and derivatives
for the first quarter of 2005. These amounts included net losses of $2.1 million
on financial instruments held as economic hedges of the mortgage servicing
rights. The Company's use of securities as an economic hedge of mortgage
servicing rights is more-fully discussed in the Line of Business - Mortgage
Banking section of this report. During the first quarter of 2004, BOK Financial
recognized net gains on securities and derivatives of $3.3 million, including
net gains of $2.2 million on securities held as economic hedges.

Other Operating Expense

Other operating expense for the first quarter of 2005 totaled $102.2 million, a
12% decrease from the same period of 2004. This decrease resulted primarily from
a $9.3 million reduction in the provision for impairment of mortgage servicing
rights. Additionally, operating expenses for the first quarter of 2004 included
$4.1 million for the cost of appreciated securities contributed to the BOK
Charitable Foundation.

Personnel expense

Personnel expense totaled $58.4 million for the first quarter of 2005 compared
with $58.2 million for the first quarter of 2004. Regular compensation expense
totaled $38.5 million, a $2.1 million, or 6%, increase over the first quarter of
2004. The increase in regular compensation expense was due to a 3% increase in
average regular compensation per full-time equivalent employee and a 3% increase
in average staffing.

Incentive compensation decreased $3.7 million, or 30%, from the first quarter of
2004 to $8.8 million in the first quarter of 2005. Stock-based compensation
expense decreased $4.2 million in the first quarter of 2005 compared to the same
period of 2004. Much of this expense is related to stock-based compensation that
is recognized from liability awards. Compensation expense for these awards is
based on the excess of the fair value of BOK Financial common stock over a set
exercise price. Incentive compensation expense for these awards varies directly
with changes in the fair value of BOKF's common stock, which decreased during
the quarter. Expense for other incentive compensation plans increased $489
thousand, or 5% primarily due to performance measured against established goals.

Employee benefit expenses increased $1.8 million, or 19%, over the first quarter
of 2004 to $11.2 million. Employee insurance costs increased $1.5 million, or
62%. Approximately half of the increase was due to an increase in the number of
employees covered and higher medical service costs. The remainder of the growth
in employee insurance costs reflected a small number of significant claims.
Expenses from these claims can be volatile because the Company self-insures a
portion of its employee health care coverage.

Data processing and communications expense

Data processing and communication expenses increased $458 thousand, or 3%, in
the first quarter of 2005 compared to the same period of 2004. This expense
consists of two broad categories, data processing systems and transaction card
processing. Transaction card processing costs increased $446 thousand, or 9%,
due to growth in processing volumes. Data processing systems costs were flat
compared with the first quarter of 2004.

Other expenses

Mortgage banking expenses, excluding provision for impairment of mortgage
servicing rights, decreased $2.2 million in the first quarter of 2005 compared
to the same period of 2004. The decrease reflected both lower costs associated
with loan origination and sales activities and a reduction in the amortization
of mortgage servicing rights. These expenses are discussed more fully in the
Line of Business - Mortgage Banking section of this report.

Income Taxes

Income tax expense was $29.5 million for the first quarter of 2005, compared
with $20.4 million for the first quarter of 2004. This represented 36% and 34%,
respectively, of book taxable income. Income tax expense for the first quarter
of 2004 was reduced by $1.2 million from the contribution of appreciated
securities to the BOK Charitable Foundation. Excluding this item, income tax
expense would have been $21.6 million, or 36% of book taxable income.

Lines of Business

BOK Financial operates five principal lines of business: Oklahoma Corporate
Banking, Oklahoma Consumer Banking, Mortgage Banking, Wealth Management, and
Regional Banking. Mortgage Banking activities include loan origination and
servicing across all markets served by the Company. Wealth Management provides
brokerage and trading, private financial services and investment advisory
services in all markets, along with fiduciary services in all markets except
Colorado. Fiduciary services in Colorado, which were a core business of Colorado
State Bank and Trust, are included in Regional Banking. Regional Banking
consists primarily of corporate and consumer banking activities in the
respective local markets. 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

 7

of the accounts. The expected duration ranges from 90 days for certain
rate-sensitive deposits to five years. The transfer-pricing rate for deposits
with indeterminate maturities increased during the first quarter of 2005 by more
than the actual cost of these funds. Net interest revenue increased in the
business units that provide deposits to the Company, such as Oklahoma Consumer
Banking, Wealth Management and Regional Banking, to more appropriately reflect
the economic value of deposits as interest rates rise.

Economic capital is assigned to the business units by a third-party developed
capital allocation model that reflects management's assessment of risk. 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 Banking line of business based on our investment in those entities.

Oklahoma Corporate Banking

The Oklahoma Corporate Banking Division provides loan and lease financing and
treasury and cash management services to businesses throughout Oklahoma and
certain relationships in surrounding states. In addition to serving the banking
needs of small businesses, middle market and larger customers, the Oklahoma
Corporate Banking Division has specialized groups that serve customers in the
energy, agriculture, healthcare and banking/finance industries, and includes the
TransFund network. The Oklahoma Corporate Banking Division contributed $16.6
million, or 32%, of consolidated net income for the first quarter of 2005. This
compares to $15.4 million, or 39%, of consolidated net income for the first
quarter of 2004. Growth in net income provided by this banking division came
primarily from improved credit quality. Net loans charged off decreased from
$2.8 million in the first quarter of 2004 to $397 thousand in the first quarter
of 2005.

Oklahoma Consumer Banking

The Oklahoma 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 the Internet. 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 $4.3 million, or 8%, of consolidated net income for the first
quarter of 2005. This compares to $2.0 million, or 5%, of consolidated net
income for the first quarter of 2004. Net interest revenue for the Oklahoma
Consumer Banking Division increased $3.0 million, or 28%, due to growth in
average assets and an increase in transfer pricing credit to units that provide
lower-costing funds to the Company. Performance of the Oklahoma Consumer Banking
Division also improved due to a reduction in net loans charged off.

Mortgage Banking

BOK Financial engages in mortgage banking activities through the BOk Mortgage
Division of Bank of Oklahoma. These activities include the origination,
marketing and servicing of conventional and government-sponsored mortgage loans.
Mortgage banking activities contributed $2.3 million, or 4%, of consolidated net
income in the first quarter of 2005 compared to $353 thousand, or 1%, in 2004.
The improved performance of the Mortgage Banking line of business was due to
increased value of mortgage servicing rights.

Mortgage banking activities consisted of two sectors, loan production and loan
servicing. The loan production sector generally performs best when mortgage
rates are relatively low and loan origination volumes are high. Conversely, the
loan servicing sector generally performs best when mortgage rates are relatively
high and prepayments are low.

Loan Production Sector

Loan production revenue totaled $1.5 million for the first quarter of 2005,
including $2.0 million of capitalized mortgage servicing rights, compared to
loan production revenue of $3.9 million in the first quarter of 2004, including
$2.7 million of capitalized mortgage servicing rights. The decrease in loan
production revenue was due to decreased production volume caused by rising
mortgage interest rates. Mortgage loans funded in the first quarter of 2005
totaled $119 million compared with $160 million in the first quarter of 2004.
Approximately 70% of the loans funded during the first quarter of 2005 were in
Oklahoma. The decreased volume of loans funded resulted in a pre-tax loss from
loan production of $138 thousand for the first quarter of 2005 compared with
pre-tax income of $1.9 million for the first quarter of 2004. The pipeline of
mortgage loan applications totaled $250 million at March 31, 2005, compared $189
million at December 31, 2004 and $300 million at March 31, 2004.

 9

Loan Servicing Sector

The loan servicing sector had pre-tax income of $3.4 million for the first
quarter of 2005 compared to a pre-tax loss of $2.5 million for the same period
of 2004. A 40 basis point increase in mortgage interest rates during the first
quarter of 2005 increased the value of servicing rights and resulted in a $5.6
million reduction in the valuation allowance. Losses of $2.1 million were
recognized on financial instruments held as an economic hedge of the value of
the servicing rights. During the first quarter of 2004, $3.7 million was
provided for impairment of mortgage servicing rights, partially offset by net
gains of $2.2 million on financial instruments designated as an economic hedge.

Servicing revenue totaled $4.1 million in the first quarter of 2005 compared
with $4.7 million in the same period of 2004. 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 $3.7 billion during the
first quarter of 2005 compared to $4.1 billion during the first quarter of 2004.
The decrease in loans serviced reflected both the continued refinancing of
mortgage loans and our decision to curtail purchases of mortgage loan servicing.
Annualized servicing revenue per outstanding loan principal was 45 basis points
for each quarter.

Amortization of mortgage servicing rights, which is included in operating
expense, was $3.2 million in the first quarter of 2005 compared to $5.2 million
in the first quarter of 2004. Amortization expense is determined in proportion
to the estimated future cash flows that will be generated by the mortgage
servicing rights. The reduction in amortization expense reflected an expectation
of lower loan prepayment speeds.

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. Additionally,
interest rate derivative contracts may also be designated as an economic hedge
of the risk of loss on mortgage servicing rights. Because the fair values of
these instruments are expected to vary inversely to the fair value of the
servicing rights, they are expected to partially offset risk. However, no
special hedge accounting treatment is applicable to either the mortgage
servicing rights or the financial instruments designated as an economic hedge.
We may sell these securities and realize gains or losses when necessary to
offset the impairment provision of the mortgage servicing rights. Derivative
contracts used to hedge mortgage servicing rights are carried at fair value with
changes in fair value recognized in earnings.

This hedging strategy presents certain risks. A well-developed market determines
the fair value for the securities and 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.

 10

At March 31, 2005, financial instruments with a fair value of $165 million were
held for the economic hedge program. The interest rate sensitivity of the
mortgage servicing rights and securities held as a hedge is modeled over a range
of +/- 50 basis points. At March 31, 2005, the pre-tax results of this modeling
on reported earnings were:

Wealth Management contributed $4.4 million, or 8%, to consolidated net income
for the first quarter of 2005. This compared to $2.6 million, or 7%, of
consolidated net income for the same period of 2004.

Trust and private financial services provided $3.9 million of net income in the
first quarter of 2005, a 65% increase over the same period in 2004. Net interest
revenue increased $1.2 million due to growth in average assets and an increase
in transfer pricing credit to units that provide funds to the Company. Other
operating revenue increased $2.0 million due to trust and mutual fund fees. At
March 31, 2005 and 2004, Wealth Management was responsible for trust assets with
aggregate market values of $23.3 billion and $19.9 billion, respectively. The
growth in trust assets reflected increased market value in addition to new
business generated during the year. Trust assets also increased $195 million due
to the regulatory change required of all banks in the valuation method for oil
and gas properties. We have sole or joint discretionary authority over $8.3
billion of trust assets at March 31, 2005 compared to $7.9 billion of trust
assets at March 31, 2004. Growth in the fair value of trust assets came
primarily in non-managed assets, which increased by $1.6 billion, or 21%, and
custodial assets which increased by $1.4 billion, or 34%.

Brokerage and trading activities provided $510 thousand of net income in the
first quarter of 2005 compared to $266 thousand in the first quarter of 2004.

Regional Banking

Regional Banking consists primarily of the corporate and commercial banking
services provided by Bank of Texas, Bank of Albuquerque, Bank of Arkansas, and
Colorado State Bank and Trust in their respective markets. It also includes
fiduciary services provided by Colorado State Bank and Trust. Small businesses
and middle-market corporations are Regional Banking's primary customer focus.
Regional Banking contributed $17.1 million, or 33%, of consolidated net income
during the first quarter of 2005. This compares with $14.1 million, or 36%, of
consolidated net income for the same period in 2004. Growth in net income
contributed by the regional banks came primarily from operations in Texas and
New Mexico. Net income for the first quarter of 2005 in Texas and New Mexico
increased $2.2 million and $1.4 million, respectively.

Growth in net income from Texas operations resulted from an increase in net
interest revenue. Average earning assets increased $229 million, including $156
million of loans and $82 million of funds sold to the funds management unit. The
growth in average earning assets was funded by a $127 million increase in
interest-bearing deposits and a $70 million increase in average demand deposits.

The increase in net income from New Mexico operations was also based largely on
an increase in net interest revenue. Average earning assets increased $92
million, including $60 million of loans and $32 million of funds sold to the
funds management unit. Average deposits in the New Mexico market increased $65
million, including $70 million of interest-bearing deposits. Average demand
deposits decreased $5 million.

Colorado State Bank and Trust's performance for the first quarter of 2005 was
adversely affected by $1.6 million of net loans charged off. This level of net
charge-offs was due to the resolution of several commercial lending
relationships that pre-dated our acquisition of CSBT.

Financial Condition

Securities

Securities are classified as either held for investment or available for sale
based upon asset/liability management strategies, liquidity and profitability
objectives and regulatory requirements. Investment securities, which consist
primarily of Oklahoma municipal bonds, are carried at cost and adjusted for
amortization of premiums or accretion of discounts. Management has the ability
and intent to hold these securities until they mature. Available for sale
securities, which may be sold prior to maturity, are carried at fair value.
Unrealized gains or losses, less deferred taxes, are recorded as accumulated
other comprehensive income in shareholders' equity.

The amortized cost of available for sale securities at March 31, 2005 totaled
$4.7 billion compared with $4.6 billion at December 31, 2004. Mortgage-backed
securities continued to represent substantially all available for sale
securities. As previously discussed in the Net Interest Revenue section of this
report, we hold mortgage backed securities as part of our overall interest rate
risk management strategy.

The primary risk of holding mortgage-backed securities comes from extension
during periods of rising interest rates or prepayment during periods of falling
interest rates. We evaluate this risk through extensive modeling of risk both
before making an investment and throughout the life of the security. The
expected duration of the mortgage-backed securities portfolio was approximately
3.2 years at March 31, 2005 and December 31, 2004.

Net unrealized losses on available for sale securities totaled $80 million at
March 31, 2005 compared with net unrealized losses of $16 million at December
31, 2004 due primarily to rising interest rates. Net unrealized losses
represented 1.6% of the securities portfolio at March 31, 2005, compared with
0.3% at December 31, 2004. The aggregate gross amount of unrealized losses at
March 31, 2005 totaled $89 million. Management evaluated the securities with
unrealized losses to determine if we believe that the losses were temporary.
This evaluation considered factors such as causes of the unrealized losses and
prospects for recovery over various interest rate scenarios and time periods. We
also considered our intent and ability to hold the securities until the fair
values exceeded amortized cost. It is our belief, based on currently available
information and our evaluation, that the unrealized losses in these securities
are temporary.

Loans

The aggregate loan portfolio at March 31, 2005 totaled $8.1 billion, a $157
million, or 8%, annualized increase since December 31, 2004.

The commercial loan portfolio increased $15 million during the first quarter of
2005. Much of this increase was focused in the services portion of the
portfolio, which increased $90 million, or 6%. As of March 31, 2005, services
comprised 21% of the total loan portfolio and included $293 million of loans to
nursing homes and $149 million of loans to medical facilities. Energy loans
totaled $1.2 billion or 15% of total loans as of March 31, 2005. Outstanding
energy loans decreased $49 million, or 4%, during the first quarter of 2005.
High energy prices provided cash flow to the industry which resulted in reduced
outstanding loan balances during the first quarter of the year. Approximately
$977 million of outstanding loans at March 31, 2005 was to oil and gas
producers. The amount of credit available to these customers generally depends
on a percentage of the value of their proven energy reserves based on
anticipated prices. The energy category also included loans to borrowers
involved in the transportation and sale of oil and gas and to borrowers that
manufacture equipment or provide other services to the energy industry.

As of March 31, 2005, agriculture loans included $221 million of loans to the
cattle industry. Other notable loan concentrations by primary industry of the
borrowers are presented in Table 14.

BOK Financial participates in shared national credits when appropriate to obtain
or maintain business relationships with local customers. Shared national credits
are defined by banking regulators as credits of more than $20 million and with
three or more non-affiliated banks as participants. At March 31, 2005, the
outstanding principal balance of these loans totaled $889 million, including
$886 million to borrowers within local markets. BOK Financial is the agent
lender in approximately 24% of its shared national credits, based on the number
of relationships. The Company's lending policies generally avoid loans in which
we do not have the opportunity to maintain or achieve other business
relationships with the customer.

Commercial real estate loans totaled $1.7 billion, or 21%, of the loan portfolio
at March 31, 2005. The outstanding balance of commercial real estate loans
increased $97 million since December 31, 2004. As of March 31, 2005,
construction and land development included $397 million for single family
residential lots and premises, up $48

 15

million, or 14%, since December 31, 2004. This growth resulted from expanded
builder loans, primarily in New Mexico and Arizona. The major components of
other commercial real estate loans were retail facilities - $312 million and
office buildings $377 million. Commercial real estate loans secured by office
buildings increased $53 million, or 10%, during the quarter.

Residential mortgage loans, excluding loans held for sale, included $347 million
of home equity loans, $285 million of loans held in conjunction with business
relationships, $237 million of adjustable rate mortgages and $316 million of
loans held for community development. Community development loans increased $37
million, or 13% during the first quarter of 2005 as part of the Company's
ongoing efforts to more directly serve its local communities. Consumer loans
included $257 million of indirect automobile loans. Substantially all of these
loans were purchased from dealers in Oklahoma.

Table 15 presents the distribution of the major loan categories among our
primary market areas.

Loan Commitments

BOK Financial enters into certain off-balance sheet arrangements in the normal
course of business. These arrangements included loan commitments which totaled
$3.5 billion and standby letters of credit which totaled $613 million at March
31, 2005. Loan commitments may be unconditional obligations to provide financing
or conditional obligations that depend on the borrower's financial condition,
collateral value or other factors. Standby letters of credit are unconditional
commitments to guarantee the performance of our customer to a third party. Since
some of these commitments are expected to expire before being drawn upon, the
total commitment amounts do not necessarily represent future cash requirements.

Derivatives with Credit Risk

BOK Financial offers programs that permit its customers to hedge various risks,
including fluctuations in energy and cattle prices, interest rates and foreign
exchange rates. Each of these programs work essentially the same way. Derivative
contracts are executed between the customers and the Company. Offsetting
contracts are executed between the Company and selected counterparties to
minimize the risk to us of changes in commodity prices, interest rates, or
foreign exchange rates. The counterparty contracts are identical to the customer
contracts, except for a fixed pricing spread or a fee paid as compensation for
administrative costs, credit risk and profit.

These programs create credit risk for potential amounts due to the Company from
its customers and from the counterparties. Customer credit risk is monitored
through existing credit policies and procedures. The effects of changes in
commodity prices, interest rates or foreign exchange rates are evaluated across
a range of possible price changes to determine the maximum exposure we are
willing to have individually to any customer. Customers may also be required to
provide margin collateral to further limit our credit risk.

Counterparty credit risk is evaluated through existing policies and procedures.
This evaluation considers the total relationship between BOK Financial and each
of the counterparties. Individual limits are determined by management based on
established policies. Margin collateral is required if the exposure between the
Company and any counterparty exceeds established limits. Based on declines in
the counterparties' credit rating, these limits are reduced and additional
margin collateral is required.

A deterioration of the credit standing of one or more of the counterparties to
these contracts 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 the counterparty
deteriorated such that either the fair value of underlying collateral 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, 2005, the fair
value of derivative contracts reported as assets under these programs totaled
$720 million. This included energy contracts with fair values of $705 million,
interest rate contracts with fair values of $5 million and foreign exchange
contracts with fair values of $10 million. The aggregate fair values of
derivative contracts reported as liabilities totaled $722 million. At December
31, 2004, the fair values of assets and liabilities reported under these
programs totaled $379 million and $380 million, respectively. The increase in
fair values of assets and liabilities was driven primarily by increases in
energy prices. New customer relationships added approximately $80 million in
fair value of derivative assets and liabilities during the quarter.
Approximately 69% of the fair value of asset contracts was with customers. The
credit risk of these contracts is generally backed by energy production. The
remaining 31% was with counterparties. The maximum net exposure to any single
customer or counterparty totaled $66 million at March 31, 2005.

Summary of Loan Loss Experience

The reserve for loan losses, which is available to absorb losses inherent in the
loan portfolio, totaled $109 million at March 31, 2005 and December 31, 2004,
and $115 million at March 31, 2004. These amounts represented 1.35%, 1.38% and
1.55% of outstanding loans, excluding loans held for sale, at March 31, 2005,
December 31, 2004 and March 31, 2004, respectively. Losses on loans held for
sale, principally mortgage loans accumulated for placement into security pools,
are charged to earnings through adjustment in the carrying value. The reserve
for loan losses also represented 219% of outstanding balance of nonperforming
loans at March 31, 2005, compared with 206% at December 31, 2004 and 248% at
March 31, 2004. Net loans charged off during the first quarter of 2005 totaled
$3.2

 17

million, down from $5.8 million for the first quarter of 2004.

Credit risk from loan commitments and letters of credit are considered in the
evaluation of the adequacy of the reserve for loan losses. A separate reserve
for off-balance sheet credit risk is maintained. Table 16 presents the trend of
reserves for off-balance sheet credit losses and the relationship between the
reserve and loan commitments. The relationship between the combined reserve for
credit losses and outstanding loans is also presented to facilitate comparison
with peer banks and others who have not adopted this preferred presentation. The
provision for credit losses included the combined charge to expense for both the
reserve for loan losses and the reserve for off-balance sheet credit losses. All
losses incurred from lending activities will ultimately be reflected in
charge-offs against the reserve for loan losses. Losses on outstanding
commitments would occur after the commitment is funded and collection efforts
are exhausted.

Specific impairment reserves are determined through evaluation of estimated
future cash flows and collateral value. At March 31, 2005, specific impairment
reserves totaled $5.6 million on total impaired loans of $43.5 million. Required
specific impairment reserves decreased $2.3 million from December 31, 2004.

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 risk factor identified. At March 31,
2005, the ranges of potential losses for the more significant factors were:

General economic conditions - $7 million to $11 million
Concentration in large loans - $2 million to $3 million

The provision for credit losses totaled $2.0 million for the first quarter of
2005, compared with $4.4 million for the fourth quarter of 2004 and $7.0 for the
first quarter of 2004. Factors which contributed to the lower provision included
a general trend toward improved grading of commercial loans and a reduction in
the outstanding balances of criticized loans, a reduction in the number of past
due consumer loans, and a reduction in net losses incurred. These factors were
partially offset by concerns about increased concentration in loans to
commercial real estate borrowers and to residential home builders. The factors
that evidence credit quality have generally improved over the past two years and
no indication of a change in this overall trend is anticipated in the near
future.

Nonperforming Assets

Information regarding nonperforming assets, which totaled $53 million at March
31, 2005 and $56 million at December 31, 2004, is presented in Table 17.
Nonperforming assets included nonaccrual and renegotiated loans and excluded
loans 90 days or more past due but still accruing interest. Nonaccrual loans
totaled $50 million at March 31, 2005 and $53 million at December 31, 2004.
Newly identified nonaccruing loans totaled $6 million during the first quarter
of 2005. Nonaccruing loans decreased $2 million for loans charged off and
foreclosed, and $7 million for cash payments received.

The loan review process also identified loans that possess more than the normal
amount of risk due to deterioration in the financial condition of the borrower
or the 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 were not included in
Nonperforming Assets. Known information does, however, cause management concerns
as to the borrowers' ability to comply with current repayment terms. These
potential problem loans totaled $41 million at March

 19

31, 2005 and $49 million at December 31, 2004. The current composition of
potential problem loans by primary industry included healthcare - $10 million,
manufacturing - $10 million, real estate - $6 million and energy - $5 million.


Deposits

Deposit accounts represent our primary funding source. We compete for retail and
commercial deposits by offering a broad range of products and services and
focusing on customer convenience. Retail deposit growth is supported through our
Perfect Banking program, free checking and on-line Billpay services, an
extensive network of branch locations and ATMs and a 24-hour Express Bank call
center. Commercial deposit growth is supported by offering treasury management
and lockbox services.

Growth in average deposits slowed to a 2% annualized rate for the first quarter
of 2005 after increasing 7% during 2004. Core deposits, which we define as
deposits of less than $100,000, excluding public funds and brokered deposits,
decreased at an annualized rate of 5%. This was offset by an 11% annualized
increase in deposits with balances in excess of $100,000. Average core deposits
comprised 52% of total deposits for the first quarter of 2005, down from 54% for
the preceding quarter. Deposit accounts with balances in excess of $100,000
represented 37% of total deposits for the first quarter of 2005, compared with
36% of total deposits for both the fourth quarter and first quarter of 2004.

The distribution of deposit accounts among our principal markets is shown in
Table 18. Growth in deposits in Colorado showed the results of a targeted
campaign designed to increase penetration in that market.

Borrowings and Capital

Parent Company

BOK Financial (parent company) has a $125 million unsecured revolving line of
credit with certain banks that matures in December 2006. The outstanding
principal balance of this credit agreement was $95 million at March 31, 2005.
Interest is based on LIBOR plus a defined margin that is determined by the
principal balance outstanding and our credit rating or a base rate. The base
rate is defined as the greater of the daily federal funds rate plus 0.5% or the
prime rate. This credit agreement includes certain restrictive covenants that
limit our ability to borrow additional funds and to pay cash dividends on our
common stock. These covenants also require BOK Financial and subsidiary banks to
maintain minimum capital levels and to exceed minimum net worth ratios. BOK
Financial met all of the restrictive covenants at March 31, 2005.

The primary source of liquidity for BOK Financial is dividends from subsidiary
banks, which are limited by various banking regulations to net profits, as
defined, for the preceding two years. Dividends are further restricted by
minimum capital requirements. Based on the most restrictive limitations, the
subsidiary banks could declare up to $159 million of dividends without
regulatory approval. Management has developed and the Board of Directors has
approved an internal capital policy that is more restrictive than the regulatory
capital standards. The subsidiary banks could declare dividends of up to $111
million under this policy.

Equity capital for BOK Financial increased $17 million to $1.4 billion at March
31, 2005. Net income provided $52 million to this increase, partially offset by
a $39 million increase in net unrealized losses on available for sale
securities. The remaining increase in capital during the first quarter of 2005
resulted primarily from activity in employee stock options.

Capital is managed to maximize long-term value to the shareholders. Factors
considered in managing capital include projections of future earnings, asset
growth, acquisition strategies, and regulatory and debt covenant requirements.
Capital management may include subordinated debt issuance, share repurchase and
stock and cash dividends. On April 26, 2005, the Board of Directors authorized a
share repurchase program, which replaced a previously authorized program. The
maximum of two million common shares may be repurchased. The specific timing and
amount of shares repurchased will vary based on market conditions, securities
law limitations and other factors. Repurchases may be made over time in open
market or privately negotiated transactions. The repurchase programs may be
suspended or discontinued at any time without prior notice.

On April 26, 2005, the Board of Directors approved quarterly cash dividend of
$0.10 per common share. The dividend will be payable on May 31, 2005 to
shareholders of record on May 13, 2005. This cash dividend replaced the annual
dividend historically paid in shares of common stock. We have been advised that
holders of the Company's convertible preferred stock will exercise their
conversion rights on or before May 13, 2005. An additional 6,920,666 common
shares will be issued, including 6,907,280 common shares to our principal
shareholder.

BOK Financial and subsidiary banks are subject to various capital requirements
administered by federal agencies. Failure to meet minimum capital requirements
can result in certain mandatory and possibly additional discretionary actions by
regulators that could have material impact on operations. These capital
requirements include quantitative measures of assets, liabilities, and
off-balance sheet items. The capital standards are also subject to qualitative
judgments by the regulators. The capital ratios for BOK Financial are presented
in Table 19. At March 31, 2005, BOK Financial and each of its banking
subsidiaries exceeded the regulatory definition of well-capitalized.

Off-Balance Sheet Arrangements

During 2002, BOK Financial issued shares of common stock and options to purchase
additional shares with a fair value of $65 million 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. BOK Financial may elect, in its sole
discretion, to issue additional shares of common stock or to pay cash to satisfy
any obligation under the price guaranty.

We will have no obligation to issue additional common shares or pay cash to
satisfy any benchmark price protection obligation if the market value per share
of BOK Financial common stock remains above the highest benchmark price of
$42.53. Based on the closing price of BOK Financial common stock on March 31,
2005 of $40.68 per share, the maximum obligation under this agreement would be
to issue 9,549 additional shares or to pay $388 thousand.

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 3.2 years while the related
funds borrowed have an average duration of 90 days.

BOK Financial also uses interest rate swaps in managing its interest rate
sensitivity. These products are generally used to more closely match interest on
certain fixed-rate loans with funding sources and long-term certificates of
deposit with earning assets. During the first quarters of 2005 and 2004, net
interest revenue increased $366 thousand and $2.5 million, respectively, from
periodic settlements of these contracts. These contracts are carried on the
balance sheet at fair value and changes in fair value are reported in income as
derivatives gains or losses. A net gain of $495 thousand was recognized in 2005
compared to a net loss of $995 thousand in 2004 from adjustments of these swaps
and hedged liabilities to fair value. Credit risk from these swaps is closely
monitored as part of our overall process of managing credit exposure to other
financial institutions.

 23

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.

Our primary interest rate exposures included the Federal Funds rate, which
affects short-term borrowings, and the prime lending rate and LIBOR, 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 20 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 exceptions.

Management 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, 2005, the VAR was $455 thousand. The
greatest value at risk during the quarter was $814 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 and valuation of
mortgage servicing rights 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.

Notes to Consolidated Financial Statements (Unaudited)


(1) Accounting Policies

Basis of Presentation

The unaudited consolidated financial statements of BOK Financial Corporation
("BOK Financial") have been prepared in accordance with accounting principles
for interim financial information generally accepted in the United States and
with the instructions to Form 10-Q and Article 10 of Regulation S-X.
Accordingly, they do not include all of the information and footnotes required
by generally accepted accounting principles for complete financial statements.
In the opinion of management, all adjustments (consisting of normal recurring
accruals) considered necessary for a fair presentation have been included.

The unaudited consolidated financial statements include the accounts of BOK
Financial and its subsidiaries, principally Bank of Oklahoma, N.A. and its
subsidiaries ("BOk"), Bank of Texas, N.A., Bank of Arkansas, N.A., Bank of
Albuquerque, N.A., Colorado State Bank and Trust, N.A., and BOSC, Inc. Certain
prior period amounts have been reclassified to conform to current period
classifications.

The financial information should be read in conjunction with BOK Financial's
2004 Form 10-K filed with the Securities and Exchange Commission, which contains

(1)      The Company had a stock repurchase plan that was initially authorized
         by the Company's board of directors on February 24, 1998 and amended on
         May 25, 1999. Under the terms of that plan, the Company could

         authorization and replaced it with a new stock repurchase plan
         authorizing the Company to repurchase up to two million shares of the
         Company's common stock.

(2)      The Company routinely repurchases mature shares from employees to
         cover the exercise price and taxes in connection with employee stock
         option exercises.
