Performance Summary

BOK Financial Corporation reported earnings of $53.9 million or $0.80 per
diluted share for the second quarter of 2007, compared with net income of $55.0
million or $0.82 per diluted share for the second quarter of 2006. The returns
on average assets and shareholders' equity were 1.16% and 12.06%, respectively
for the second quarter of 2007, compared with returns of 1.33% and 14.03%,
respectively for the second quarter of 2006. Year-to-date net income was $106.7
million or $1.58 per diluted share for 2007 and $109.7 million or $1.63 per

eleven bank locations in the Denver, Colorado area. These acquisitions did
not significantly affect average asset, average liabilities or net income
for the second quarter.

of 2007.

o Provision for credit losses was $7.8 million for the second quarter of
2007, up from $3.8 million for the second quarter of 2006 and $6.5 million
for the first quarter of 2007. Non-performing assets totaled $60 million or

Results of Operations

Net Interest Revenue

Tax-equivalent net interest revenue increased to $137 million for the second
quarter of 2007 from $123 million for the same period of 2006, due primarily to
a $1.9 billion or 20% increase in average outstanding loan principal. Average
loan growth was funded by a $1.2 billion or 10% increase in average deposits and
a $809 million increase in borrowed funds. 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 3.31% for the second quarter of 2007, compared with 3.40% for
the second quarter of 2006 and 3.32% for the first quarter of 2007. The yield on
average earning assets was 7.00%, up 29 basis points compared with the second
quarter of 2006 and down 2 basis points over the preceding quarter. Beginning in
2005, the weighted average spread of rates earned on our commercial loan
portfolio over LIBOR funding sources decreased from approximately 272 basis
points to approximately 239 basis points due largely to competitive pricing
pressure. Over the same period, deposit account balances have been steadily
migrating to higher costing products. Non-interest bearing funds and changes in
the mix of funding sources added 43 basis points to the net interest margin in
second quarter of 2007 compared with 42 basis points for the second quarter of
2006 and 44 basis points for the preceding quarter.

Management regularly models the effects of changes in interest rates on net
interest revenue. Based on this modeling, we expect net interest revenue to
decline slightly from rising rates over a one-year forward looking period.
However, other factors such as loan spread compression, deposit product mix and
overall balance sheet composition may affect this general expectation.
Additionally, we have a large portion of our assets in mortgage-backed
securities. These securities reprice as cash flow received is reinvested at
current market rates. The resulting change in yield of the securities portfolio
occurs more slowly than changes in market rates. The tax-equivalent yield of the
securities portfolio for the second quarter of 2007 increased 13 basis points
compared with the same period of 2006 while the average loan yield increased 26
basis points and the cost of interest-bearing liabilities increased 39 basis
points.

Our overall objective is to manage the Company's balance sheet to be relatively
neutral to changes in interest rate. Approximately 69% 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 would be asset sensitive, which means that assets generally
4

reprice more quickly than liabilities. Among the strategies that we use to
achieve a relatively rate-neutral position, we purchase fixed-rate,
mortgage-backed securities to offset the short-term nature of the majority of
the Company's funding sources. 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. Interest
rate swaps with a combined notional amount of $632 million convert fixed rate
liabilities to floating rate based on LIBOR. The purpose of these derivatives,
which include interest rate swaps designated as fair value hedges, is to
position our balance sheet to be relatively neutral to changes in interest
rates. We also have interest rate swaps with a notional amount of $100 million
that convert prime-based loans to fixed rate. The purpose of these derivatives,
which have been designated as cash flow hedges, also is to position our balance
sheet to be relatively neutral to changes in interest rates.

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 the Market Risk section of
this report.

</TABLE>

Year-to-date tax equivalent net interest revenue totaled $267.9 million, up 11%
over 2006. Average earning assets increased $2.0 billion or 14%. Net interest
margin was 3.31% for the first half of 2007 compared with 3.40% for the first
half of 2006. The yield on average earning assets was 7.01%, up 44 basis points
over the first half of 2006. The cost of interest-bearing liabilities was 4.13%,
up 55 basis points over last year. Non-interest-bearing funds and changes in the
mix of funding sources added 43 basis points to the net interest margin in the
first half of 2007 and 41 basis points in the first half of 2006.

Other Operating Revenue

Other operating revenue increased $1.1 million compared with the second quarter
of 2006. Fees and commission revenue increased $4.9 million or 5%. Growth in fee
revenue was offset by a $3.7 million increase in losses on securities, including
securities held as an economic hedge of our mortgage servicing rights.

Diversified sources of fees and commission revenue are a significant part of our
business strategy and represented 42% of total revenue, excluding gains and
losses on asset sales, securities and derivatives, for the second quarter of
2007.
5

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.

Fees and commissions revenue

Transaction card revenue increased $3.0 million or 15% over the second quarter
of 2006. ATM network revenue increased $1.8 million or 21% due to additional
locations added in the second half of 2006 while check card revenue increased
$1.1 million or 22% over the second quarter of 2006 due to volume growth.
Merchant discount fees increased 1% over the second quarter of 2006.

Trust fees and commissions increased $1.7 million or 10% for the second quarter
of 2007. The fair value of all trust relationships, which is the basis for a
significant portion of trust fees increased to $33.7 billion at June 30, 2007
compared with $28.7 billion at June 30, 2006. Personal trust management fees,
which provide 31% of total trust fees and commissions increased $297 thousand or
5%. Employee benefit plan management fees, which provide 19% of total trust
fees, grew $360 thousand or 11%. Net fees from mutual fund advisory and
administrative services increased $626 thousand or 17%. Revenue from the
management of oil and gas properties and other real estate, which provide 10% of
total trust revenue, increased 2% over the second quarter of 2006.

Brokerage and trading revenue grew $720 thousand or 6%. Revenue from retail
brokerage activities increased $864 thousand or 24% over the same period of
2006. Revenue from securities trading activities increased $606 thousand or 13%.
Customer hedging revenue decreased $191 thousand or 6% due to lower revenue from
energy hedging. Investment banking fees were down $560 thousand or 48% due to
the timing of transaction closings.

Deposit service charges and fees increased $456 thousand or 2% over the second
quarter of 2006. Overdraft fees grew $721 thousand or 4% due to increased volume
while service charges on retail accounts decreased $286 thousand or 17% due to
service-charge free deposit products. Commercial deposit account fees were
largely unchanged compared with the second quarter of 2006.

Mortgage banking revenue decreased $513 thousand or 7% compared with 2006.
Servicing revenue totaled $4.3 million for the second quarter of 2007, up $37
thousand over the same period last year. Net gains on mortgage loans sold
totaled $2.4 million, down $550 thousand from the second quarter of 2006.

Changes in the cash surrender value of life insurance provided revenue of $2.5
million in the second quarter of 2007 and $32 thousand in the second quarter of
2006. The Company invested $202 million in bank-owned life insurance during the
third quarter of 2006. The increase in revenue earned on life insurance is
partially offset by a decrease in net interest revenue due to increased costs to
fund insurance assets.

Other operating revenue included $969 thousand of fees earned on margin assets
in the second quarter of 2007 and $3.6 million in the second quarter of 2006.
Margin assets which are held primarily as part of the Company's customer
derivatives programs averaged $96 million for the second quarter of 2007,
compared with $260 million for the second quarter of 2006. The decrease in
revenue earned on margin assets is partially offset by an increase in net
interest revenue due to lower costs to fund the margin assets.

Year-to-date fees and commissions revenue grew $7.0 million or 4% over 2006.
Other revenue decreased $6.2 million due primarily to lower margin interest fees
while revenue from bank-owned life insurance increased $4.8 million. Transaction
card revenue was up $4.6 million or 12% due to increases in transaction volumes
and the number of ATM locations. Trust fees increased $2.8 million or 8% due
largely to growth in the fair value of trust assets. Brokerage and trading
revenue and deposit service charges each grew 2% over the same period last year.

Securities and derivatives

BOK Financial recognized net losses of $6.3 million on securities for the second
quarter of 2007, including net losses of $5.7 million on securities held as an
economic hedge of mortgage servicing rights. Securities held as an economic
hedge of the mortgage servicing rights which are separately identified on the
balance sheet as "mortgage trading securities" are carried at fair value.
Changes in fair value are recognized in earnings as they occur. 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 second quarter of 2006, BOK Financial recognized net losses
of $2.5 million on securities held as an economic hedge of mortgage servicing
rights and net losses of $1.3 million on other securities.

Net losses on derivatives totaled $183 thousand for the second quarter of 2007,
compared with net losses of $172
6

thousand in 2006. Net gains or losses on derivatives consist of fair value
adjustments of derivatives used to manage interest rate risk and the related
hedged liabilities.

Other Operating Expense

Other operating expense for the second quarter of 2007 totaled $136.0 million, a
$13.8 million increase from 2006. Increases in the fair value of mortgage
servicing rights decreased operating expenses by $5.1 million in the second
quarter of 2007 and $3.6 million in the second quarter of 2006. Excluding
changes in the value of mortgage servicing rights, operating expenses increased
$15.3 million or 12% over the second quarter of 2006 due primarily to higher
personnel expense.

Personnel expense

Personnel expense totaled $81.9 million for the second quarter of 2007 compared
with $72.4 million for the second quarter of 2006.

</TABLE>

Regular compensation expense increased $6.8 million or 15% over the second
quarter of 2006. The increase in regular compensation expense was due to a 7%
increase in average regular compensation per full-time equivalent employee and
an 8% increase in average staffing. Growth in average compensation per full-time
equivalent employee reflects the cost of hiring top talent to support expansion
in the regional markets, product development, and technology.

Incentive compensation expense includes the recognized costs of cash-based
commissions, bonus and incentive
7

programs, stock-based compensation plans and deferred compensation plans.
Stock-based compensation plans include both equity and liability awards.

Second quarter 2007 expense for the Company's various cash-based incentive
programs totaled $13.7 million, up $580 thousand or 4% over last year. These
programs consist primarily of formula-based plans that determine incentive
amounts based on pre-established growth criteria. Compensation expense for
stock-based compensation plans totaled $3.1 million for the second quarter of
2007 and $2.4 million for the second quarter of 2006. Compensation expense for
stock-based compensation plans accounted for as equity awards totaled $1.7
million in the second quarter of 2007, compared with $1.6 million in the second
quarter of 2006. Expense for these awards is determined by award's grant-date
fair value and is not affected by subsequent changes in the market value of BOK
Financial common stock. Compensation expense for stock-based compensation plans
accounted for as liability awards was $1.4 million for the second quarter of
2007, compared with $794 thousand in 2006. Expense for these liability awards is
based on current fair value, including current period changes due to the market
value of BOK Financial common stock. The market value of BOK Financial common
stock increased $3.89 per share during the second quarter of 2007 and $2.12 per
share during the second quarter of 2006.

Employee benefit expenses totaled $12.8 million for the second quarter of 2007
and $11.4 million for the second quarter of 2006 due to higher medical insurance
costs, increased participation in the Company's thrift plan and payroll taxes.

Data processing and communications expense

Data processing and communication expenses increased $2.2 million or 14%
compared with the second quarter of 2006. This expense consists of two broad
categories, data processing systems and transaction card processing. Data
processing systems costs increased $1.8 million or 19% compared with the second
quarter of 2006, including increased hardware and software purchases and related
maintenance costs for expansion in treasury services, customer hedging and
mortgage loan origination activities. Transaction card processing costs
increased $423 thousand or 6% due to growth in transaction volume.

Professional fees and services

Professional fees totaled $6.0 million for the second quarter of 2007, up $1.6
million or 37% over the second quarter of 2006. The increase in professional
fees included costs related to the Worth and First United acquisitions and the
issuance of $250 million of subordinated debt during the second quarter of 2007.

Year-to-date operating expenses increased $29.0 million or 12%, $22.2 million or
9% excluding changes in the fair value of mortgage servicing rights. Personnel
expense grew $17.0 million or 12% due largely to growth in the average
compensation cost per employee and total employment. All other operating
expenses grew 5% over the first half of 2006.

Income Taxes

Income tax expense was $29.3 million or 35% of book taxable income for the
second quarter of 2007 compared with $31.1 million or 36% of book taxable income
for the second quarter of 2006.


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. It also provides fiduciary services in all markets
except Colorado. Fiduciary services in Colorado are included in regional
banking. Regional banking consist primarily of corporate and consumer banking
activities in the respective local markets. Worth National Bank and First United
Bank are included in regional banking results for the second quarter of 2007 in
Texas and Colorado, respectively.

In addition to its lines of business, BOK Financial has a funds management unit.
The primary purpose of this unit is to manage the Company's overall liquidity
needs and interest rate risk. Each line of business borrows funds from and
provides funds to the funds management unit as needed to support their
operations. Operating results for Funds Management and Other include the effect
of interest rate risk positions and risk management activities, the provision
for credit losses, tax-exempt income and tax credits and certain executive
compensation costs that are not attributed to the lines of business.

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

The value of funds provided by the operating lines of business to the funds
management unit is based on applicable Federal Home Loan Bank advance rates.
Deposit accounts with indeterminate maturities, such as demand deposit accounts
and interest-bearing transaction accounts, are transfer-priced at a rolling
average based on expected duration of the accounts. The expected duration ranges
from 90 days for certain rate-sensitive deposits to five years.

Economic capital is assigned to the business units by a 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.

Consolidated net income provided by the regional banking unit continued to
increase due largely to asset growth. Also, performance by business units that
generate deposits for the Company, such as the Oklahoma consumer banking unit
and the regional banking unit continued to improve due primarily to internal
funds pricing credits. Rising short-term interest rates increased the internal
transfer pricing credit provided to units that generate lower-costing funds for
the Company. Losses in Funds Management and Other was due primarily to the
transfer pricing credit provided to operating units that generate lower-costing
funds for the Company and the provision for credit losses in excess of actual
net charge-offs during the quarter.

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. Consumer banking activities
outside of Oklahoma are included in the Regional Banking division.

The Oklahoma Consumer Banking Division contributed $9.1 million or 17% to
consolidated net income for the second quarter of 2007. This compares to $8.5
million or 16% of consolidated net income for 2006. Net interest revenue, which
consisted primarily of credits for funds provided to the funds management unit,
increased $1.4 million or 8%. Average deposits attributed to this Division
increased $82 million, or 3% compared with last year, including a $22 million or
7% increase in average demand deposits. The value to the Company of these
lower-costing retail deposits continues to increase as short-term interest rates
rise. Operating revenue increased $1.2 million or 7% over last year. Check card
fees increased $771 thousand or 22% and overdraft charges increased $485
thousand or 4%. Deposit account service charges decreased $208 thousand or 18%.
Operating expenses increased $1.7 million or 8%. Personnel expense grew $675
thousand or 9%.

During the second quarter of 2007, Albertson's announced that it was selling or
closing its supermarket locations in Oklahoma, affecting 24 of our supermarket
branch locations. Twenty-one locations are being sold to four different
retailers and three locations are being closed. Management has tentatively
reached agreement with each of the purchasers to maintain BOk's twenty-one
branch locations. We do not expect the closed locations to have a significant
impact on our branch network.

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 provided net income of $122 thousand in the second
quarter of 2007, compared with $1.3 million in the second quarter of 2006. The
change in fair value of mortgage servicing rights, net of economic hedging
decreased net income $379 thousand in the second quarter of 2007 and increased
net income $660 thousand in the second quarter of 2006.

Mortgage banking activities consisted of two primary 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. Mortgage commitment rates
increased 39 basis points during the second quarter of 2007 ending the quarter
at 6.45%. During the second quarter of 2006, mortgage commitment rates increased
36 basis points to 6.61% at June 30, 2006.

Loan Production Sector

Loan production activities resulted in net pre-tax income of $331 thousand for
the second quarter of 2007 and pre-tax income of $696 thousand for the second
quarter of 2006. Loan production revenue totaled $4.1 million for the second
quarter of 2007, including $3.6 million of capitalized mortgage servicing
rights. Loan production revenue totaled $3.4 million for the second quarter of
2006, including $3.3 million of capitalized mortgage servicing rights. Mortgage
loans funded in the second quarter of 2007 totaled $315 million, including $256
million of loans funded for resale and $59 million of loans funded for retention
by affiliates. Mortgage loans funded in the same period of 2006 totaled $243
11

million. Approximately 63% of the loans funded during the second quarter of 2007
were to borrowers in Oklahoma. The pipeline of mortgage loan applications
totaled $306 million at June 30, 2007, compared with $267 million at March 31,
2007 and $276 million at June 30, 2006. Personnel expenses associated with loan
production activities increased from $677 thousand in the second quarter of 2006
to $1.4 million in the second quarter of 2007 due primarily to increased
staffing and incentive compensation rates in markets outside of Oklahoma.

Loan Servicing Sector

The loan servicing sector had a net pre-tax loss of $552 thousand for the second
quarter of 2007 compared to a pre-tax profit of $1.3 million for the same period
of 2006. The fair value of mortgage servicing rights increased $5.1 million due
to changes in commitment rates and prepayment speeds. At the same time, the fair
value of securities held as an economic hedge of the servicing rights decreased
$5.7 million. During the second quarter of 2006, the fair value of mortgage
servicing rights appreciated $3.6 million due to changes in mortgage commitment
rates and a slow-down in housing turnover. Appreciation in the value of
servicing rights was partially offset by a $2.5 million decrease in the fair
value of securities held as an economic hedge.

Servicing revenue, which is included in mortgage banking revenue on the
Consolidated Statements of Earnings, totaled $4.3 million for the second quarter
of 2007 and $4.2 million for the second quarter of 2006. The average outstanding
balance of loans serviced for others was $4.6 billion during 2007 compared to
$4.5 billion during 2006. Annualized servicing revenue per outstanding loan
principal was 37 basis points for the second quarter of 2007 and 2006.

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 designated as "mortgage
trading securities" 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. These financial
instruments are carried at fair value. Changes in fair value are recognized in
current period income. No special hedge accounting treatment is applicable to
either the mortgage servicing rights or the financial instruments designated as
an economic hedge.

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.

At June 30, 2007, financial instruments with a fair value of $139 million and a
net unrealized loss of $5.3 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 June 30,
2007, the pre-tax results of this modeling on
12

reported earnings were:

Table 9 - Interest Rate Sensitivity - Mortgage Servicing
(Dollars in Thousands)
50 bp increase 50 bp decrease
Anticipated change in:
Fair value of mortgage servicing rights $ 2,866 $ (3,760)
Fair value of hedging instruments (3,769) 3,671
----------------- ----------------
Net $ (903) $ (89)
----------------- ----------------

Table 9 shows the non-linear effect of changes in mortgage commitment rates on
the value of mortgage servicing rights. A 50 basis point increase in rates is
expected to increase value by $2.9 million while a 50 basis point decrease is
expected to reduce value by $3.8 million. This considers that there is an upper
limit to appreciation in the value of servicing rights as rates rise due to the
contractual repayment terms of the loans and other factors. There is much less
of a limit on the speed at which mortgage loans may prepay in a declining rate
environment.

Modeling changes in value of the mortgage servicing rights due to changes in
interest rates assumes stable relationships between mortgage commitment rates
and discount rates used to determine the present value of future cash flows. It
also assumes a stable relationship between assumed loan prepayments and actual
prepayments of our loans. Changes in market conditions can increase or decrease
the discount spread over benchmark rates expected by investors in mortgage
servicing rights and actual prepayment speeds may increase or decrease due to
factors other than changes in interest rates. These factors and others may cause
changes in the value of our mortgage servicing rights to differ from our
expectations. In addition, hedge coverage is a dynamic process. Securities
designated as an economic hedge will increase or decrease over time based on
management's assessment of expected changes in the value of the servicing
rights. These changes will cause the value of hedging instruments to differ from
value projected in our modeling.


Wealth Management

BOK Financial provides a wide range of financial services through its wealth
management line of business, including banking, fiduciary and brokerage
services. Clients include affluent individuals, businesses, not-for-profit

management line of business was responsible for trust assets with aggregate
market values of $30.8 billion and $26.2 billion, respectively, under various
fiduciary arrangements. The growth in trust assets reflected increased market
value of assets managed in addition to new business generated during the year.

Regional Banking

Regional Banking consists primarily of the corporate and commercial banking
services provided by Bank of Texas, Bank of Albuquerque, Bank of Arkansas,
Colorado State Bank and Trust, Bank of Arizona and Bank of Kansas City 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 $24.4
million or 45% to consolidated net income during the second quarter of 2007.
This compares with $22.4 million or 41% of consolidated net income for the same
period in 2006. Growth in net income contributed by the regional banks came
primarily from operations in Texas. Net income from Texas operations increased
$1.5 million or 12% compared with the same period of 2006. In addition, net
income for 2007 in Colorado and Arizona increased $716 thousand and $107
thousand, respectively. Net income in New Mexico decreased $246 thousand from
last year.

Net income from Texas operations totaled $14.0 million for the second quarter of
2007, up $1.5 million or 12% over last year. Net charge-offs / recoveries
improved from a $1.8 million pre-tax loss in the second quarter of 2006 to a
$609 thousand pre-tax recovery in the second quarter of 2007. Net interest
revenue grew $2.6 million or 7%. Average earning assets increased $347 million
or 10% from the second quarter of 2006. This increase resulted from a $506
million increased in average outstanding loan balances and an $111 million
increase in securities. The growth in average earning assets was funded
primarily by a $278 million increase in average deposits and a decrease in funds
sold to the funds management unit. Operating expenses increased $3.1 million or
15%. Personnel costs were up $2.1 million or 18% over the same period last year.

Net income from operations in Colorado was $4.0 million for the second quarter
of 2007, compared with $3.3 million for the second quarter of 2006. Net interest
revenue increased $1.7 million or 19% due primarily to a $426 million increase
in average earning assets. Average loans increased $200 million while average
securities and funds sold to the funds management unit increased $226 million.
The growth in earning assets was funded primarily by a $239 million increase in
deposits and borrowings from the funds management unit. Other operating revenue
grew $307 thousand or 11% due primarily to trust fees and commissions. At June
30, 2007 and 2006, Colorado regional banking was responsible for trust assets
with aggregate fair values of $2.9 billion and $2.5 billion, respectively under
various fiduciary arrangements. We have sole or joint discretionary authority
over $1.1 billion of trust assets at June 30, 2007, compared with $955 million
at June 30, 2006. Operating expenses increased $796 thousand or 12% including a

Financial Condition

Securities

Securities are classified as either held for investment, available for sale or
trading based upon asset/liability management strategies, liquidity,
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. Certain mortgage-backed
securities, identified as mortgage trading securities, have been designated as
economic hedges of mortgage servicing rights. These securities are carried at
fair value with changes in fair value recognized in current period income. These
securities are held with the intent that gains or losses will offset changes in
the fair value of mortgage servicing rights. The Company also maintains a
separate trading securities portfolio. Trading portfolio securities, which are
also carried at fair value with changes in fair value recognized in current
period income, are acquired and held with the intent to sell at a profit.

The amortized cost of available for sale securities totaled $5.1 billion at June
30, 2007 and $4.8 billion at March 31, 2007. 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
effective duration of the mortgage-backed securities portfolio was approximately
2.8 years at June 30, 2007 and 2.5 years at March 31, 2007. Management estimates
that the effective duration of the mortgage-backed securities portfolio would
extend to 3.4 years assuming a 300 basis point immediate rate shock.

The gross amount of unrealized losses on available for sale securities totaled
$140 million at June 30, 2007 compared with gross unrealized losses of $83
million at March 31, 2007. The increase in unrealized losses during the quarter
was due primarily to rising interest rates and an increase in the spread between
market rates on mortgage-backed securities and benchmark interest rates.
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. The portfolio does not hold any
securities backed by sub-prime mortgage loans, collateralized debt obligations
or collateralized loan obligations. Approximately $400
17

million of Alt-A mortgage-backed securities were held at June 30, 2007. Alt-A
mortgage loans generally include loans that lack some documentation required of
prime loans such as verified borrower income or assets and loans to borrowers
where credit scores fall between the definitions of sub-prime and prime.
Approximately 77% of the Alt-A backed securities, including all Alt-A
mortgage-backed securities originated in 2006 and 2007, are AAA rated and are
credit enhanced with additional collateral support. Management does not believe
that any of the unrealized losses are due to credit quality concerns. Changes in
market rates and conditions reduced the gross unrealized loss on available for
sale securities to $105 million at July 31, 2007. We also considered our intent
and ability to either hold or sell the securities. It is our belief, based on
currently available information and our evaluation, that the unrealized losses
in these securities are temporary.

Bank-Owned Life Insurance

During the third quarter of 2006, the Company invested $202 million in
bank-owned life insurance. This investment is expected to provide a long-term
source of earnings to support existing employee benefit obligations.
Substantially all of the funds are held in separate accounts and invested in
U.S. government, mortgage-backed and corporate debt securities. The cash
surrender value of the life insurance policies is further supported by a stable
value wrap, which protects against changes in the fair value of the investments.
The cash surrender value of the policies, including the value of the stable
value wrap, was $201 million at June 30, 2007. In addition to investment in the
separate accounts, $8 million of the amount invested paid taxes on the insurance
premiums. These taxes will be recovered over a ten-year period. At June 30,
2007, a $7 million receivable was recorded based on the present value of the
taxes. The Company also has life insurance policies obtained through various
bank acquisitions with an aggregate cash surrender value of $16 million.

Loans

The aggregate loan portfolio at June 30, 2007 totaled $11.7 billion, a $556
million increase since March 31, 2007. The acquisitions of Worth National Bank
and First United Bank added $378 million to the loan portfolio during the second
quarter. Excluding acquisitions, the loan portfolio grew at an annualized rate
of 6%. Commercial and commercial real estate loan growth was partially offset by
approximately $140 million of payoffs of energy, healthcare and real estate
loans. These payoffs affected the outstanding loan balances in the Texas, New
Mexico and Arizona markets. Excluding acquisitions, commercial loans increased
$38 million or 2% annualized and commercial real estate loans were unchanged
during the quarter. Residential mortgage loans and consumer loans increased $43
million and $59 million, respectively.

The commercial loan portfolio totaled $6.5 billion at June 30, 2007. Energy
loans totaled $1.8 billion or 16% of total loans. Outstanding energy loans
increased $62 million, or 14% annualized, during the second quarter of 2007.
Approximately $1.6 billion of loans in the energy portfolio 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. The
services sector of the portfolio totaled $1.7 billion, or 14% of the Company's
total outstanding loans. Loans in this sector of the portfolio increased $90
million since March 31, 2007. The services sector consists of a large number of
loans to a variety of businesses, including communications, gaming and
transportation services. Approximately $1.1 billion of the services sector is
made up of loans with balances of less than $10 million.

Other notable loan concentrations by primary industry of the borrowers are
presented in Table 16.

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. The outstanding principal
balances of these loans totaled $1.5 billion at June 30, 2007 and $1.4 billion
at March 31, 2007. Substantially all of these loans were to borrowers with local
market relationships. BOK Financial serves as the agent lender in approximately
24% of the shared national credits, based on dollars committed. Our 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 $2.8 billion or 24% of the loan portfolio
at June 30, 2007. Construction and land development loans totaled $917 million,
down $9 million since March 31, 2007. Construction and land development included
$718 million of loans secured by single family residential lots and premises,
unchanged from the previous quarter's end. The major components of other
commercial real estate loans were office buildings - $434 million and retail
facilities - $396 million.

Residential mortgage loans, excluding mortgage loans held for sale, included
$415 million of home equity loans, $449 million of loans held for business
relationship purposes, $317 million of first lien adjustable rate mortgages and
$152 million of loans held for community development. Consumer loans included
$554 million of indirect automobile loans. Indirect auto loans have increased
$53 million since March 31, 2007. Approximately $416 million of these loans were
purchased from dealers in Oklahoma and $124 million were purchased from dealers
in Arkansas. Growth during the quarter included $25 million from indirect
lending activities in Arkansas and $23 million in Oklahoma.

Loan Commitments

BOK Financial enters into certain off-balance sheet arrangements in the normal
course of business. These arrangements included loan commitments which totaled
$5.4 billion and standby letters of credit which totaled $519 million at June
30, 2007. Loan commitments may be unconditional obligations to provide financing
or conditional obligations that
20

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, or to take positions in derivative contracts. Each of these
programs work essentially the same way. Derivative contracts are executed
between the customers and BOK Financial. 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 to us as compensation for administrative
costs, credit risk and profit.

The Company adopted Statement of Financial Accounting Standards No. 157, "Fair
Value Measurement" ("FAS 157") as of January 1, 2007. FAS 157 established a
single authoritative definition of fair value, set out a framework for measuring
fair value and required additional disclosures about fair value measurements. It
also nullified EITF guidance that prohibited recognition of gains at inception
for derivative transactions whose fair value is estimated by modeling.

Beginning January 1, 2007, the fair value of customer derivative assets and
liabilities fully reflects the discounted cash flows based on forward curves,
volatilities, credit risks and other market-observable inputs. Changes in the
net fair values of customer derivative contracts are a component of Brokerage
and Trading Revenue. Retained earnings were charged $1.1 million for effect of
the initial adoption of FAS 157 on the fair value of customer derivative assets
and liabilities.

The customer derivative programs create credit risk for potential amounts due
from 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 options 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 established by management, approved
by Credit Administration and reviewed by the Asset / Liability Committee. 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 customers or
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
customer or 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 June 30, 2007, the fair value
of derivative contracts reported as assets under these programs totaled $265
million. This included energy contracts with fair values of $203 million,
interest rate contracts with fair values of $45 million and foreign exchange
contracts with fair values of $15 million. The aggregate fair values of
derivative contracts reported as liabilities totaled $277 million. Approximately
78% of the fair value of asset contracts was with customers. The credit risk of
these contracts is generally backed by energy production. The remaining 22% was
with dealer counterparties. The maximum net exposure to any single customer or
counterparty totaled $34 million.


Summary of Loan Loss Experience

The reserve for loan losses, which is available to absorb losses inherent in the
loan portfolio, totaled $120 million at June 30, 2007, compared with $114
million at March 31, 2007 and $105 million at June 30, 2006. These amounts
represented 1.03%, 1.03% and 1.07% of outstanding loans, excluding loans held
for sale, at June 30, 2007, March 31, 2007 and June 30, 2006, respectively.
Losses on loans held for sale, principally mortgage loans accumulated for
21

placement into security pools, are charged to earnings through adjustment in the
carrying value. The reserve for loan losses also represented 230% of outstanding
balance of non-accruing loans at June 30, 2007, compared with 365% at March 31,
2007 and 337% at June 30, 2006. Non-accruing loans totaled $52 million at June
30, 2007, compared with $31 million at March 31, 2007 and June 30, 2006. Net
loans charged off during the second quarter of 2007 totaled $5.8 million, up
from $3.1 million in the preceding quarter and $3.8 million for the second
quarter of 2006. Net charge-offs were disbursed among our operating regions and
across borrowers' industries with no significant concentration in any area.

Loans with an outstanding balance of $92 million acquired from First United Bank
are subject to a guaranty by the sellers through an escrow fund held in trust by
Colorado State Bank and Trust. The Company will be reimbursed for up to $8
million on losses, including principal, interest and collection costs, on any
acquired loans in a three-year period after the acquisition date.

The Company considers credit risk from loan commitments and letters of credit in
its evaluation of the adequacy of the reserve for loan losses. A separate
reserve for off-balance sheet credit risk is maintained. Table 18 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 following funds
advanced against outstanding commitments and after the exhaustion of collection
efforts. The reserve for off-balance sheet credit losses would decrease and the
reserve for loan losses would increase as outstanding commitments are funded.

Specific impairment reserves are determined through evaluation of estimated
future cash flows and collateral value. At June 30, 2007, specific impairment
reserves totaled $2.9 million on total impaired loans of $44 million. Required
specific impairment reserves were $2.4 million at March 31, 2007.

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. The ranges of
potential losses for the more significant factors were:

The provision for credit losses totaled $7.8 million for the second quarter of
2007, compared with $6.5 million for the first quarter of 2007 and $3.8 million
for the second quarter of 2006. Factors considered in determining the provision
for credit losses included increases in net losses and non-accruing loans during
the quarter along with continued growth in outstanding loans.

Nonperforming Assets

Information regarding nonperforming assets, which totaled $60 million at June
30, 2007, $41 million at March 31, 2007 and $39 million at June 30, 2006, is
presented in Table 19. Nonperforming assets included non-accrual loans and
excluded loans 90 days or more past due but still accruing interest. Non-accrual
loans totaled $52 million at June 30, 2007, including $6.9 million of
non-accrual loans subject to the First United Bank seller's guaranty (see Note
2). Non-accrual loans totaled $31 million at March 31, 2007 and at June 30,
2006. Newly identified non-accruing loans totaled $22 million during the second
quarter of 2007 and acquisitions increased non-accruing loans $7.8 million.
Newly identified non-accruing loans were disbursed among our geographic regions
and across our loan portfolio. No significant concentrations were identified.
Non-accruing loans decreased $5.9 million for loans charged off or foreclosed,
and $4.8 million for cash payments received.

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 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 $45 million at June 30, 2007 and $27 million at
March 31, 2007. Potential problem loans by primary industry included healthcare
- - $23 million, services - $14 million and real estate - $6 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.

Total deposits averaged $12.4 billion for the second quarter of 2007, up $314
million, or 10% annualized compared with average deposits in the first quarter
of 2007. Average deposits attributed to funds management, which includes
23

brokered deposits and public funds, increased $103 million to $1.1 billion for
the second quarter. In addition, deposits provided by the Worth National Bank
acquisition averaged $126 million for the second quarter of 2007. Average
commercial deposits decreased $7.3 million or 1%. Average deposits attributed to
consumer banking increased $17 million or 1%. Average deposits attributed to
trust and private financial services increased $69 million or 19% annualized.

Core deposits, which we define as deposits of less than $100,000, excluding
public funds and brokered deposits, averaged $6.4 billion for the second quarter
of 2007, an annualized increase of 36% over the first quarter of 2007. Average
core deposits comprised 51% of total deposits for the second quarter of 2007.
Deposit accounts with balances in excess of $100,000 averaged $4.7 billion or
38% of total average deposits, down from $5.1 billion for the preceding quarter.

The distribution of deposit accounts among our principal markets is shown in
Table 20.

Borrowings and Capital

BOK Financial (parent company) has a $100 million unsecured revolving line of
credit with certain banks that expires in December 2010. There was no
outstanding principal balance on this credit agreement at June 30, 2007.
Interest is based on LIBOR plus a defined margin that is determined by the
Company's credit rating or a base rate. This margin ranges from 0.375% to
1.125%. The margin currently applicable to borrowings against this line is
0.375%. The base rate is defined as the greater of the daily federal funds rate
plus 0.500% or the SunTrust Bank prime rate. Interest is generally paid monthly.
Facility fees are paid quarterly on the unused portion of the commitment at
rates that range from 0.100% to 0.250% based on the Company's credit rating.

This credit agreement includes certain restrictive covenants that limit the
Company's ability to borrow additional funds, to make investments and to pay
cash dividends on 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 June 30,
2007.

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. After issuing dividends in the second quarter of
2007 to fund acquisitions, the subsidiary banks could declare up to $35 million
of dividends based on the most restrictive limitations 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 $18 million
under this policy.

Equity capital for BOK Financial totaled $1.8 billion at June 30, 2007, up $10
million during the quarter. Retained earnings, net income less cash dividends
provided $40 million of the increase. Accumulated other comprehensive losses
increased $33 million due primarily to net unrealized losses on available for
sale securities. Employee stock option transactions increased equity capital $4
million during the second quarter of 2007.

Capital is managed to maximize long-term value to the shareholders. Factors
considered in managing capital include projections of future earnings, asset
growth and 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. During the second quarter of
2007, the Company repurchased 18,783 common shares at an average price of $51.49
per share. The Company may repurchase 1.7 million common shares in the future
under this program.

Cash dividends of $13.5 million or $0.20 per common share were paid during the
second quarter of 2007. On July 31, 2007 the Board of Directors approved
quarterly cash dividend of $0.20 per common share. The dividend will be payable
on or about August 30, 2007 to shareholders of record on August 15, 2007.

BOK Financial and its 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.

For a banking institution to qualify as well capitalized, its Tier 1, Total and
Leverage capital ratios must be at least 6%, 10% and 5%, respectively. All of

During the second quarter of 2007, Bank of Oklahoma issued $250 million of
subordinated debt due May 15, 2017. Interest on this debt is based on a fixed
rate of 5.75% through May 14, 2012 and on a floating rate of three-month LIBOR
plus 0.69% thereafter. The proceeds of this debt, which qualifies as Tier 2
regulatory capital, was used to fund the Worth National Bank and First United
Bank acquisitions and to fund continued asset growth.

Off-Balance Sheet Arrangements

During 2002, BOK Financial agreed to a limited price guarantee on a portion of
the common shares issued to purchase of Bank of Tanglewood. Any holder of BOK
Financial common shares issued in this acquisition may annually make a claim for
the excess of the guaranteed price over 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 final anniversary date of this guarantee is October 25,
2007. The maximum annual number of shares subject to this guarantee is 210,069.
The price guarantee is non-transferable and non-cumulative. 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 guarantee. The Company 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. The
closing price of BOK Financial common stock on June 30, 2007 was $53.42 per
share.

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 position the balance sheet to be neutral to
interest rate changes. As previously noted in the Net Interest Revenue section
of this report, management acquires securities that are funded by borrowings in
the capital markets. The average duration of these securities is expected to be
approximately 2.8 years based on a range of interest rate and prepayment
assumptions.

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 variable-rate loans with funding sources and long-term certificates of
deposit
28

with earning assets. During the second quarter of 2007, net interest revenue was
reduced by $2.1 million from periodic settlements of these contracts. Net
interest revenue was decreased by $2.1 million from periodic settlements of
these contracts in the second quarter of 2006. These contracts are carried on
the balance sheet at fair value and changes in fair value are reporting in
income as derivatives gains or losses. Net losses of $183 thousand and $172
thousand were recognized in the second quarters of 2007 and 2006, respectively,
from adjustments of these swaps and hedged liabilities to fair value. Credit
risk from interest rate swaps is closely monitored as part of our overall
process of managing credit exposure to other financial institutions.

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 12 and 24 months based on eight interest
rate scenarios. Two specified interest rate scenarios are used to evaluate
interest rate risk against policy guidelines. The first scenario assumes a
sustained parallel 200 basis point increase and the second assumes a sustained
parallel 200 basis point decrease in interest rates. The Company also performs a
sensitivity analysis based on a "most likely" interest rate scenario, which
includes non-parallel shifts in interest rates. An independent source is used to
determine the most likely interest rate scenario.

The Company's 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 22 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.

Management uses a Value at Risk ("VAR") methodology to measure the market risk
inherent in its trading activities.
29

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 $1.8 million. At June
30, 2007, the VAR was $558 thousand. The greatest value at risk during the
quarter was $1.2 million.


Controls and Procedures

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


Forward-Looking Statements

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

Notes to Consolidated Financial Statements (Unaudited)

(1) Accounting Policies

Basis of Presentation

The unaudited consolidated financial statements of BOK Financial Corporation
("BOK Financial" or "the Company") 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 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., Bank of Arizona, N.A.,
Bank of Kansas City, N.A., and BOSC, Inc. Certain prior period amounts have been
reclassified to conform to current period classification.

The financial information should be read in conjunction with BOK Financial's
2006 Form 10-K filed with the Securities and Exchange Commission, which contains
audited financial statements. Amounts presented as of December 31, 2006 have
been derived from BOK Financial's 2006 Form 10-K.

Newly Adopted and Pending Accounting Policies

BOK Financial adopted Statement of Financial Accounting Standards No. 157, "Fair
Value Measurement" (FAS 157") as of January 1, 2007. FAS 157 established a
single authoritative definition of fair value, set out a framework for measuring
fair value and required additional disclosures about fair value measurements. It
also nullified EITF guidance that prohibited recognition of gains at inception
for derivative transactions whose fair value is estimated by modeling.

Beginning January 1, 2007, the fair value of customer derivative assets and
liabilities fully reflects the discounted cash flows based on forward curves,
volatilities, credit risks and other market-observable inputs. Changes in the
net fair values of customer derivative contracts are a component of Brokerage
and Trading Revenue. Retained earnings were charged $679 thousand for the
after-tax effect of the initial adoption of FAS 157 on the fair value of
customer derivative assets and liabilities. FAS 157 did not have a significant
effect on other fair value measurements in the Company's financial statements.

The Company adopted Financial Accounting Standards Board Interpretation No. 48,
"Accounting for Uncertainty in Income Taxes" ("FIN 48"), effective January 1,
2007. FIN 48 requires that an uncertain tax position must be more likely than
not of being upheld upon audit by the taxing authority for the benefit to be
recognized. The benefit of uncertain tax positions that do not meet this
criterion may not be recognized. In addition, FIN 48 requires that the amount of
tax benefit that may be recognized for uncertain positions that meet the
recognition criterion shall consider the amounts and probabilities of outcomes
that could be realized upon settlement. BOK Financial recognized a $609 thousand
increase in the liability for unrecognized tax benefits, which was accounted for
as a reduction to the January 1, 2007 balance of retained earnings. As of the
date of adoption, total unrecognized tax benefits were $12.6 million, including
the amount recognized in retained earnings. These unrecognized tax benefits, if
recognized in the future, could affect the effective tax rate. Interest and
penalties accrued related to unrecognized tax benefits are included in income
tax expense. As of January 1, 2007, the Company had $2 million total interest
and penalties accrued. Federal statute remains open for federal tax returns
filed in the previous three reporting periods. Various state income tax statutes
remain open for the previous three to six reporting periods. The IRS intends to
audit the 2005 consolidated United States income tax return for Worth
Bancorporation Inc. The Company purchased Worth on May 31, 2007. The Company
does not believe that the outcome of this examination will have a material
impact on its financial statements, including total unrecognized tax benefits.

The Financial Accounting Standards Board issued Statement of Financial
Accounting Standards No. 159, "The Fair Value Option for Financial Assets and
Financial Liabilities" ("FAS 159") during the first quarter of 2007. The purpose
of FAS 159 is to increase the use of fair value measurements in financials
statements and to mitigate volatility in reported earnings caused by measuring
related assets and liabilities differently without having to apply
35

complex hedge accounting provisions. FAS 159 permits financial statement issuers
an option to measure eligible financial assets and financial liabilities at fair
value. Unrealized gains and losses on assets and liabilities measured at fair
value are reported in earnings. The option to measure eligible assets and
liabilities is applied on an instrument-by-instrument basis, is irrevocable and
is applied to the entire instrument. FAS 159 is effective as of the beginning of
the first fiscal year that begins after November 15, 2007 and may be adopted as
of a fiscal year that begins on or before November 15, 2007, subject to certain
conditions. The Company expects to adopt FAS 159 as required on January 1, 2008.
The effect of FAS 159 on the Company's financial statements has not yet been
determined.


(2) Acquisitions

On May 31, 2007, BOK Financial paid $127 million in cash for all the outstanding
stock of Texas-based Worth Bancorporation. Worth had total assets of
approximately $410 million, including net loans of $281 million, and total
deposits of $369 million and five branches in the Fort Worth market. A
preliminary allocation of the purchase price to the net assets acquired is as
follows (in thousands):

Cash and cash equivalents $ 45,238
Funds sold 41,325
Securities 22,676
Loans 284,039
Less reserve for loan losses (3,528)
----------------
Loans, net of reserve 280,511
Premises and equipment, net 6,214
Core deposit premium 13,741
Other assets 15,029
----------------
Total assets acquired 424,734
----------------
Deposits 369,343
Other borrowings 7,217
Other liabilities 8,759
----------------
Net assets acquired 39,415
Less purchase price 127,067
----------------
Goodwill $ 87,652
----------------


On June 18, 2007, BOK Financial paid $43 million in cash for all the outstanding
stock of Colorado-based First United Bank. First United had total assets of
approximately $166 million, including loans of $94 million, and total deposits
of $133 million and eleven banking locations in the Denver area. Loans acquired
from First United Bank are subject to a guaranty by the sellers through an
escrow fund held in trust by Colorado State Bank and Trust. The Company will be
reimbursed for up to $8 million of losses, including principal, interest and
collection costs, on acquired loans in a three-year period after the acquisition
date. Accordingly, none of the purchase price was allocated to an allowance for
loan losses. A preliminary allocation of the purchase price to the net assets
acquired is as follows (in thousands):

Cash and cash equivalents $ 4,376
Funds sold 32,091
Securities 2,245
Loans 93,810
Premises and equipment, net 31,749
Other assets 2,050
Core deposit premium 5,039
----------------
Total assets acquired 171,360
----------------
Deposits 133,342
Other borrowings 2,138
Other liabilities 7,362
----------------
Net assets acquired 28,518
Less purchase price 42,796
----------------
Goodwill $ 14,278
----------------
36

The results of operations of these acquisitions would not have been significant
to the Company's consolidated results during the pre-acquisition periods of 2007
and 2006.

During the first quarter of 2007, the Company paid approximately $425 thousand
to acquire a charter for Bank of Kansas City in order to begin full-service
banking operations in Missouri. Previously, the Company's full-service banking
rights were restricted to Kansas City, Kansas. The Company currently has two
full-service banking locations in the Kansas City market.


(3) Fair Value Measurements

Fair value measurements as of June 30, 2007 are as follows (in thousands):

<TABLE>

</TABLE>

(1) A reconciliation of the beginning and ending fair value of mortgage
servicing rights and disclosures of significant assumptions used to
determine fair value are presented in Note 5, Mortgage Banking
Activities.


The fair value of assets and liabilities based on significant other observable
inputs are generally provided to us by third-party pricing services and are
based on one or more of the following:

o Quoted prices for similar, but not identical, assets or liabilities in
active markets;

o Quoted prices for identical or similar assets or liabilities in
inactive markets;

o Inputs other than quoted prices that are observable, such as interest
rate and yield curves, volatilities, prepayment speeds, loss
severities, credit risks and default rates;

o Other inputs derived from or corroborated by observable market inputs.

The underlying methods used by the third-party pricing services are considered
in determining the primary inputs used to determine fair values.

No fair value measurements of significant assets or liabilities measured on a
non-recurring basis were made during the first half of 2007. Assets measured on
a non-recurring basis include pension plan assets, which are based on quoted
prices in active markets for identical instruments and goodwill, which is based
on significant unobservable inputs.

(5) Mortgage Banking Activities

At June 30, 2007, BOK Financial owned the rights to service 58,390 mortgage
loans with outstanding principal balances of $5.3 billion, including $566
million serviced for affiliates. The weighted average interest rate and
remaining term was 6.13% and 277 months, respectively.

In the first quarter of 2007, the Company paid approximately $3.6 million to
acquire the rights to service approximately $270 million of mortgage loans.
Substantially all of these loans are to borrowers in our primary market areas.

For the three and six months ended June 30, 2007, mortgage banking revenue
includes servicing fee income of $4.3 million and $8.5 million, respectively.
For the three and six months ended June 30, 2006, mortgage banking revenue
includes servicing income of $4.2 million and $8.3 million, respectively.

In 2006, BOK Financial implemented Statement of Financial Accounting Standards
No. 156, "Accounting for Servicing of Financial Assets." Upon implementation, an
initial adjustment of the mortgage servicing rights to fair value of
approximately $351 thousand, net of income taxes, was recognized as an increase
to retained earnings and certain securities designated as an economic hedge of
mortgage servicing rights were transferred from the available for sale
classification to trading.

Activity in capitalized mortgage servicing rights and related valuation
allowance during the six months ending June 30, 2007 is as follows (in
thousands):

plans, trusts and the general public in the ordinary course of business.
Approximately 98% of AP Fund's assets of $3.6 billion are held for BOK
Financial's clients.

On October 10, 2006, the Securities and Exchange Commission (the "SEC") started
a special examination of AXIA. The examination is focused on the BISYS Fund
Services Ohio, Inc. ("BISYS") marketing assistance agreements with AXIA that
were terminated in 2004. In September 2006, BISYS settled the SEC's two-year
investigation of it by consenting to an order in which the SEC determined that
BISYS had "willfully aided and abetted and caused" (1) the investment advisors
to 27 different families of mutual funds to violate provisions of the Investment
Advisors Act of 1940 that prohibit fraudulent conduct; (2) the investment
advisors to the 27 fund families to violate provisions of the 1940 Act that
prohibit the making of any untrue statement of a material fact in a registration
statement filed by the mutual fund with the SEC, and (3) the 27 fund families to
violate provisions of the 1940 Act that require the disclosure and inclusion of
all distribution arrangements and expenses in the fund's 12b-1 fee plan ("the
SEC BYSIS Order"). AXIA is one of the 27 advisors and the AP Funds one of the
mutual fund families to which the SEC referred. AXIA is not bound by the SEC
BISYS Order and disagrees with its findings as they relate to AXIA.

On May 4, 2007, the AP Funds demanded AXIA and/or BISYS refund to the AP Funds
$8.1 million (with interest) and reimburse the expenses of the AP Funds'
investigation of this matter (which expenses are in excess of $1 million) or
justify the appropriateness of $8.1 million of marketing arrangement
expenditures. The AP Funds further indicated that the foregoing demand was in
respect of the period from 1997 to 2004, and that it may seek further
reimbursement from AXIA and/or BISYS for periods before 1997. BOK Financial
examined the expenditures procured by AXIA pursuant to the questioned marketing
arrangements and paid or tendered for payment $1.7 million for expenses which
were or could be argued to have been improperly charged to the marketing
arrangements.

Although AXIA believes the Committee's claims against it are without merit, it
is in active settlement discussions regarding this matter. Any settlement with
the Committee would not be binding on the SEC. BOK Financial does not expect the
examination, a settlement with the Committee, or any action the SEC may take
based upon the examination to have a material adverse effect on the Company.

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


(12) Financial Instruments with Off-Balance Sheet Risk

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

As of June 30, 2007, outstanding commitments and letters of credit were as
follows (in thousands):

June 30,
2007
--------------
Commitments to extend credit $ 5,418,538
Standby letters of credit 518,923
Commercial letters of credit 18,334
