Performance Summary

BOK Financial Corporation reported a net loss of $1.2 million or $0.02 per
diluted share for the second quarter of 2008. Net income totaled $53.9 million
or $0.80 per diluted share for the second quarter of 2007 and $62.3 million or
$0.92 per diluted share for the first quarter of 2008. Net income for the six
months ended June 30, 2008 totaled $61.1 million or $0.90 per diluted share. Net
income for the six months ended June 30, 2007 totaled $106.7 million or $1.58
per diluted share. The Company recognized $87.0 million of pre-tax charges for
loan and energy derivative credit exposure to SemGroup LP in the second quarter
of 2008. These charges reduced net income by approximately $57.0 million or
$0.84 per diluted share.

Highlights of the second quarter of 2008 included:

o Net interest margin was 3.44% for the second quarter of 2008, up 13 basis
points from both the second quarter of 2007 and the first of 2008. Net
interest revenue increased 18% over the second quarter of 2007.

o Average outstanding loans increased 10% over the second quarter of 2007.
Period-end annualized loan growth rate was 8% since the end of the first
quarter of 2008.

o Non-performing assets totaled $181 million or 1.45% of outstanding loans
and repossessed assets at June 30, 2008, up from $126 million or 1.02% of
outstanding loans and repossessed assets at March 31, 2008 and $70 million
or 0.60% of outstanding loans at June 30, 2007.

o Net loans charged off and provision for credit losses were $39.0 million
and $59.3 million, respectively, for the second quarter of 2008, including
a $26.0 million charge off and a $26.3 million provision for SemGroup. Net
loans charged off and provision for credit losses were $8.9 million and
$17.6 million, respectively for the first quarter of 2008. Net loans
charged off and provision for credit losses were $5.8 million and $7.8
million, respectively for the second quarter of 2007.

o Fees and commissions revenue totaled $63.6 million for the second quarter
of 2008, compared with $97.0 million for the second quarter of 2007 and
$113.9 million for the first quarter of 2008. Brokerage and trading
revenue, which is a component of fees and commissions revenue, was reduced
by a $60.7 million charge to adjust the fair value of energy derivative
contracts with SemGroup to their estimated fair value.

o Net losses on securities, derivatives used by the Company to manage its
interest rate risk and mortgage servicing rights totaled $9.0 million for
the second quarter of 2008, compared with net losses of $1.4 million for
the second quarter of 2007 and net gains on securities, derivatives and
mortgage servicing rights of $5.0 million for the first quarter of 2008.
3

o No other than temporary impairment charges against the Company's securities
portfolio were recognized in the second quarter of 2008, compared with
charges of $5.3 million in the first quarter of 2008. The Company has no
equity investments in FNMA or FHLMC.


Credit Exposure to SemGroup, LP and Related Entities

At June 30, 2008, BOK Financial had credit exposure to SemGroup LP and related
entities of approximately $147 million consisting of $97 million from energy
derivative contracts and $50 million from loans and loan commitments. BOK
Financial is a participant in an approximately $2.4 billion working capital and
term facility to SemGroup; another commercial bank is the lead lender for this
facility. The working capital and term facility is secured by SemGroup's
inventory and accounts receivable. All of BOK Financial's energy derivative
contracts and $46 million of the loans and loan commitments to SemGroup are
secured by the working capital facility collateral. The $34 million outstanding
balance of the working capital loan was reduced by a $26 million charge off.
Included under the working capital and term facility are $11 million of letters
of credit. BOK Financial also has a $4 million participation interest in an $806
million loan secured by SemGroup's fixed and other assets.

On July 22, 2008, SemGroup LP and 24 related entities filed for bankruptcy
protection. BOK Financial assessed a range of values for SemGroup using
information currently available, including information provided by a nationally
recognized financial advisor to SemGroup. The range considers both the value of
SemGroup as a reorganized entity (going concern value) and its liquidation
value. Based on the lower end of the range of values, BOK Financial recognized a
$26.3 million charge to increase its provision for loan losses and a $60.7
million charge against trading revenue to reduce the estimated fair value of
energy derivative contracts.

The Company's net remaining credit exposure to SemGroup at June 30, 2008 totaled
approximately $60 million, including $37 million from energy derivative
contracts and $23 million of loans and loan commitments. Non-accruing loans
include $12 million from SemGroup. This amount will increase if the amounts due
under the energy derivative contracts, primarily in the third quarter of 2008,
are not paid on their contractual settlement dates. Non-accruing loans may also
increase if funding is required of all or some of $11 million of letters of
credit. Mr. Thomas S. Kivisto, President and CEO of SemGroup, LP resigned from
the Board of Directors of BOK Financial and Bank of Oklahoma, N.A. on July 16,
2008. The Company has no direct credit exposure to Mr. Kivisto.


Results of Operations

Net Interest Revenue and Net Interest Margin

Net interest revenue totaled $158.9 million for the second quarter of 2008, up
$24.0 million or 18% over the second quarter of 2007 and $11.8 million over the
first quarter of 2008. Average earning assets increased $2.1 billion or 13% over
the second quarter of 2007, including a $1.2 billion increase in average
outstanding loans and a $917 million increase in average securities. Growth in
the securities portfolio generally consisted of highly-rated, fixed-rate
mortgage-backed securities. These securities were purchased to take advantage of
widened spreads caused by short-term disruptions in the mortgage-backed
securities markets.

Growth in average earning assets was funded primarily by a $1.9 billion or 48%
increase in average federal funds purchased and other borrowed funds. In
addition, average deposits were up $915 million or 7% over the second quarter of
2007. Average interest-bearing transaction accounts grew $1.3 billion or 20% and
average time deposits decreased $431 million or 10% compared with the second
quarter of 2007. Average demand deposits increased $41 million or 3%.

Funds generated by growth in deposits and borrowings were also used to fund a
$667 million increase in average margin assets. Margin assets are placed by the
Company to secure its obligations under various derivative contracts. Margin
assets are generally reported as a reduction of the derivative liabilities which
they secure on the Company's consolidated balance sheet. Fees earned on margin
assets are included in fees and commissions revenue.

Net interest margin was 3.44% for the second quarter of 2008 compared with 3.31%
for both the second quarter of 2007 and the first quarter of 2008. Widening of
the spread between LIBOR and the federal funds rate increased net interest
margin. LIBOR is the basis for interest earned on many of our loans. The federal
funds rate is the basis for interest paid on many of our interest-bearing
liabilities. Yields on average earning assets decreased 139 basis points to
5.61% and the cost of interest-bearing liabilities decreased 183 basis points to
2.29% compared with the second quarter of 2007. Loan yields decreased 215 basis
points to 5.79% while securities yields increased 24 basis points to 5.14%. Our
securities re-price as cash flow received is reinvested at current market rates.
The resulting change in yield on the securities portfolio
4

occurs more slowly than changes in market rates. The cost of interest bearing
deposits decreased 147 basis points to 2.22% and the cost of funds purchased and
other borrowings decreased 288 basis points. Competition for deposits in all our
markets limited our ability to move deposit rates down as interest rates
declined. The benefit to the net interest margin from earning assets funded by
non-interest bearing liabilities was 12 basis points in the second quarter of
2008 compared with 43 basis points in the second quarter of 2007 and 25 basis
points in 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
decrease slightly over a one-year forward looking period. However, other factors
such as loan spread compression, deposit product mix, the overall balance sheet
composition and the previously noted widening of the spread between LIBOR and
the federal funds rate may affect this general expectation.

Our overall objective is to manage the Company's balance sheet to be relatively
neutral to changes in interest rates. Approximately 67% of our commercial and
commercial real estate loan portfolios are either variable rate or fixed rate
that will re-price within one year. These loans are funded primarily by deposit
accounts that are either non-interest bearing, or that re-price more slowly than
the loans. The result is a balance sheet that would be asset sensitive, which
means that assets generally re-price 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 $410 million
convert fixed rate liabilities to floating rate based on LIBOR. The purpose of
these derivatives 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.

Other Operating Revenue

Other operating revenue decreased $34.6 million compared with the second quarter
of last year. Fees and commission revenue decreased $33.4 million. The decrease
in fees and commission revenue included a $60.7 million charge to write down
SemGroup derivative contracts to estimated fair value, partially offset by a
$27.3 million increase in all other fees and commissions revenue sources. Net
losses on securities and derivatives used by the Company to manage its interest
rate risk during the second quarter of 2008 totaled $8.2 million, compared with
net losses on securities and derivatives of $6.4 million for the second quarter
of 2007. Other operating revenue was down $64.9 million from the first quarter
of 2008. Fees and commissions revenue decreased $50.3 million due primarily to
the write down of SemGroup derivative contracts. Net gains on securities and
derivatives used by the Company to manage its interest rate risk totaled $6.7
million for the first quarter of 2008 due primarily to Visa, Inc.'s initial
public offering.

Diversified sources of fees and commissions revenue are a significant part of
our business strategy and generally represent 40% to 45% of our total revenue,
excluding gains and losses on asset sales, securities and derivatives. 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

Brokerage and trading activities resulted in a net loss of $35.5 million for the
second quarter of 2008 due to the $60.7 million charge to write down SemGroup
derivative contracts to fair value. Excluding this charge and revenue from
transactions with SemGroup that may not be recurring, brokerage and trading
revenue totaled $23.3 million for the second quarter of 2008, up $10.6 million
or 84% over the second quarter of 2007. Revenue from trading and institutional
securities sales totaled $11.6 million in the second quarter of 2008 compared
with $5.4 million in the second quarter of 2007. Revenue from retail brokerage
activities totaled $6.2 million for the second quarter of 2008 and $4.5 million
for the second quarter of 2007. Customer hedging revenue, excluding the
write-down of derivative contracts and revenue from transactions with SemGroup,
totaled $4.0 million for the second quarter of 2008 and $2.1 million for the
second quarter of 2007.

Brokerage and trading revenue, excluding the charge to write down derivative
contracts to fair value and revenue from transactions with SemGroup, increased
$469 thousand or 8% annualized compared with the first quarter of 2008. Revenue
from trading and institutional securities sales were down $1.2 million and
revenue from retail brokerage activities were up $857 thousand from the first
quarter of 2008. Customer hedging revenue was up $106 thousand, excluding
revenue from SemGroup transactions. In addition, investment banking revenue for
the second quarter of 2008 totaled $1.4 million, up $752 thousand over the first
quarter of 2008.

Transaction card revenue increased $2.9 million or 13% over the second quarter
of 2007. ATM network revenue increased $1.3 million or 13% while check card
revenue increased $1.2 million or 20% over the second quarter of 2007 due to
volume growth. Merchant discount fees increased $296 thousand, or 4%, over the
second quarter of 2007. Transaction card revenue for the second quarter of 2008
was up $2.2 million over the first quarter of 2008 due largely to seasonal
changes. ATM network fees increased $948 thousand and merchant discount fees
increased $602 thousand due to transaction volumes. Check card revenue was up
$661 thousand over the previous quarter.

Trust fees and commissions increased $1.5 million or 8% for the second quarter
of 2008. The fair value of all trust assets, which is the basis for a
significant portion of trust revenue, totaled $34.4 billion at June 30, 2008
compared with $33.7 billion at June 30, 2007. Net fees from mutual fund advisory
and administrative services, which provide 21% of total trust fees and
commissions increased $188 thousand or 4%. Personal trust management fees, which
provide 33% of total trust fees and commissions increased $863 thousand or 14%.
Employee benefit plan management fees, which provide 19% of total trust fees,
increased $359 thousand or 10%. Trust fees and commissions increased $144
thousand or 3% annualized over the first quarter of 2008. The fair value of all
trust assets totaled $35.5 billion at March 31, 2008 or 3% more than the fair
value of all trust relationships at June 30, 2008.

Deposit service charges and fees totaled $30.2 million for the second quarter of
2008, up $3.4 million or 13% over the second quarter of 2007. Commercial deposit
account fees were up $2.6 million or 38% over the same period of 2007 due to a
decrease in earnings credit available to commercial deposit customers and an
increase in service charges to partially offset higher deposit insurance costs.
The earnings credit, which provides a non-cash method for commercial customers
to avoid incurring charges for deposit services, decreases when interest rates
fall. Overdraft fees grew $840 thousand or 5%. Service charges on retail
accounts decreased $53 thousand or 4% due to service-charge free deposit
products. Deposit service charges increased $2.5 million compared with the first
quarter of 2008. Overdraft fees were up $1.5 million. Overdraft fees are
generally lower in the first quarter of each year due to seasonal factors.
Commercial deposit account fees were up $1.0 million.
6

Mortgage banking revenue was up $3.2 million or 78% compared with 2007.
Servicing revenue totaled $4.3 million for both the second quarters of 2008 and
2007. The outstanding principal balance of mortgage loans serviced for other
totaled $5.0 billion at June 30, 2008 and $4.8 billion at June 30, 2007. Net
gains on mortgage loans sold totaled $2.9 million, up $3.2 million over the
second quarter of 2007. Mortgage loans originated totaled $362 million for the
second quarter of 2008, up 15% over the same period in 2007.

Margin asset fees totaled $4.5 million in the second quarter of 2008 and $969
thousand in the second quarter of 2007. Margin assets which are held primarily
as part of the Company's customer derivatives programs averaged $762 million for
the second quarter of 2008, compared with $96 million for the second quarter of
2007. The increase in revenue earned on margin assets is offset by a decrease in
net interest revenue due to the costs to fund the margin assets.

Securities and derivatives

Net gains and losses on securities consisted of the following:

BOK Financial recognized net losses of $5.2 million on securities for the second
quarter of 2008, net losses on securities of $6.3 million for the second quarter
of 2007 and net gains on securities of $4.6 million for the first quarter of
2008. Mortgage hedge securities held as an economic hedge of the changes in fair
value of mortgage servicing rights are carried at fair value. Changes in fair
value of these securities are recognized in earnings as they occur. During the
first quarter of 2008, the Company recorded a $5.3 million pre-tax
other-than-temporary-impairment charge to recognize the decrease in fair value
of its holdings of variable-rate perpetual preferred stock issued by seven major
banks and brokerage houses. The Company also recognized a $6.8 million gain from
the partial redemption of Visa, Inc. Class B shares as part of Visa's initial
public offering. The Company sold certain available for sale securities during
the first quarter of 2008 at a $2.9 million gain to reduce prepayment risk in
response to falling interest rates.

Net losses on derivatives totaled $3.0 million for the second quarter of 2008
and $183 thousand for the second quarter of 2007. Net gains or losses on
derivatives consist of fair value adjustments of all derivatives used to manage
interest rate risk and the related hedged assets and liabilities when
adjustments are permitted by generally accepted accounting principles.
Derivative instruments generally consist of interest rate swaps where the
Company pays a variable rate based on LIBOR and receives a fixed rate. These
swaps generally decrease in value as interest rates rise and increase in value
as interest rates fall.

The Company adopted Statement of Financial Accounting Standards No. 159, Fair
Value Option ("FAS 159") effective January 1, 2008. FAS 159 provides an option
to measure eligible financial assets and financial liabilities at fair value.
Certain certificates of deposit that were either currently designated as hedged
or had previously been designated as hedged, but no longer met the correlation
requirements of Statement of Financial Accounting Standards No. 133 were
designated as being reported at fair value when FAS 159 was first adopted. In
addition, certain certificates of deposit issued subsequent to the adoption of
FAS 159 have been designated as reported at fair value. This determination is
made when the certificates of deposit are issued based on the Company's intent
to swap the interest rate on the certificates from a fixed rate to a LIBOR-based
variable rate.

Other Operating Expense

Other operating expense for the second quarter of 2008 totaled $159.3 million,
up $25.1 million or 19% over the second quarter of 2007. Changes in the fair
value of mortgage servicing rights increased other operating expense $5.8
million. Personnel costs increased $9.5 million or 12% due largely to incentive
compensation costs. Non-personnel expenses, excluding changes in the fair value
of mortgage servicing rights, increased $9.8 million or 17% due largely to
higher deposit insurance costs and losses on mortgage loans sold with recourse.

Personnel expense

Personnel expense totaled $89.6 million for the second quarter of 2008 and $80.1
million for the second quarter of 2007. Regular compensation, which consists of
salaries and wages, overtime pay and temporary personnel cost totaled $54.0
million, up $2.2 million or 4% over the second quarter of 2007. The increase in
regular compensation expense was due primarily to an increase in average regular
compensation per full time equivalent employee. Average staffing levels were up
1% over the second quarter of last year.

</TABLE>

Incentive compensation increased $6.7 million or 43% to $22.3 million. Expense
for cash-based incentive compensation plans increased $7.0 million or 56%. These
plans are either intended to provide current rewards to employees who generate
long-term business opportunities to the Company based on growth in loans,
deposits, customer relationships and other measurable metrics or intended to
compensate employees with commissions on completed transactions. The increase in
cash-based incentive compensation over the second quarter of 2007 included a
$3.7 million increase in commissions related to brokerage and trading revenue.

The Company also provides stock-based incentive compensation plans. Stock-based
compensation plans include both equity and liability awards. Compensation
expense related to liability awards decreased $262 thousand compared with the
second quarter of 2007. This decrease reflected changes in the market value of
BOK Financial common stock. The market value of BOK Financial common stock
increased $1.22 per share in the second quarter of 2008 and increased $3.89 per
share in the second quarter of 2007. Compensation expense for equity awards
decreased $75 thousand or 5% compared with the second quarter of 2007. Expense
for equity awards is based on the grant-date fair value of the awards and is
unaffected by subsequent changes in fair value.

Employee benefit expense totaled $13.3 million, a $659 thousand or 5% increase
over 2007. Medical insurance costs were down $378 thousand or 9%. The Company
self-insures a portion of its employee health care coverage.

Data processing and communications expense

Data processing and communications expense totaled $19.5 million, up $1.1
million or 6% over the second quarter of 2007. This expense consists of two
broad categories, data processing systems and transaction card processing. Data
processing costs increased $674 thousand or 6% due to growth in processing
volumes and acquisitions during 2007. Transaction card processing costs
increased $447 thousand or 6% due to growth in processing volume.

Other operating expenses

Occupancy and equipment expenses totaled $15.1 million for the second quarter of
2008, up $1.2 million or 9% over 2007. Growth in occupancy expense was due to 24
new branch locations added in the past year, including 16 added from bank
acquisitions during the second quarter of 2007. Insurance expense increased $1.9
million compared to the second quarter of 2007 due to an increase in FDIC
insurance premiums. A one-time credit granted to eligible depository
institutions by the Federal Deposit Insurance Reform Act of 2005 to offset
deposit insurance premiums was largely used in 2007.

Mortgage banking costs included a $3.4 million increase in provision for losses
on residential mortgage loans sold with recourse. The Company's obligation to
repurchase these loans is more-fully discussed in the Loan Commitments section
of this report.

Income Taxes

Income tax benefit was $2.9 million or 71% of book taxable loss for the second
quarter of 2008 compared with $29.3 million or 35% of book taxable income for
the second quarter of 2007 and $34.4 million or 36% of book taxable income for
the first quarter of 2008. The effective tax rate for the second quarter of 2008
includes adjustments to estimated income tax expense due to the loss incurred in
the second quarter.

BOK Financial operates in numerous jurisdictions, which requires judgment
regarding the allocation of income, expense and earnings under various laws and
regulations of each of these taxing jurisdictions. Each jurisdiction may audit
our tax returns and may take different positions with respect to these
allocations. The reserve for uncertain tax positions was largely unchanged from
December 31, 2007.


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 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 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. Return on economic capital
excludes amortization of intangible assets.

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, this 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 incurred a net loss of $37.9 million for the second
quarter of 2008 due to its credit exposure from one customer, SemGroup, which
declared bankruptcy in mid July 2008. Losses on loans and derivative contracts
with SemGroup reduced the Oklahoma Corporate Banking Division's net income for
the second quarter of 2008 by $53.0 million. This Division contributed $19.0
million to consolidated net income in the second quarter of 2007 and $20.4
million to consolidated net income in the first quarter of 2008. Excluding
SemGroup losses, the Oklahoma Corporate Banking Division's net income for the
second quarter of 2008 was $15.1 million.

Net interest revenue decreased $4.0 million or 10%. Average earnings assets
attributed to this division increased $93 million or 2% over 2007 to $4.7
billion. Average loans decreased $33 million or 1% to $4.4 billion. Average
commercial loans decreased $152 million or 6%. The decrease in average
commercial loans was partially offset by a $70 million increase in average
consumer loans, primarily indirect automobile loans, and a $50 million increase
in average real estate loans. Average funds provided to the funds management
unit by the Oklahoma Corporate Banking Division increased $122 million. Average
deposits attributed to the Oklahoma Corporate Banking Division increased $206
million or 10% due primarily to growth in treasury services Eurodollar deposit
products.

Operating revenue decreased $57.6 million due primarily to a $60.7 million
charge for the decrease in the fair value of derivative contracts with SemGroup.
Operating revenue was up $3.1 million or 13% excluding this charge. Operating
revenue provided by TransFund increased $1.4 million or 15% and service charges
on commercial deposit accounts were up $1.1 million or 21%. Operating expenses,
which consist primarily of personnel and data processing costs, increased $2.8
million or 10%.

Net loans charged off by the Oklahoma Corporate Banking Division totaled $32.3
million in the second quarter of 2008, which included a $26.0 million charge off
of SemGroup loans. Excluding SemGroup, net loans charged off in the second
quarter of 2008 totaled $6.3 million or 0.54% of average loans. Net loans
charged off totaled $3.3 million or 0.30% of average loans for the second
quarter of 2007 and $2.2 million or 0.18% of average loans for the first quarter
of 2008.

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 and
BOSC's retail brokerage division. Consumer banking services are offered through
35 locations in Tulsa, 32 locations in Oklahoma City and 16 locations throughout
the state.

The Oklahoma Consumer Banking Division contributed net income of $7.6 million
for the second quarter of 2008, compared to net income of $9.1 million for the
second quarter of 2007. Net interest revenue decreased $2.8 million or 15% over
2007 due primarily to deposit spread compression. Average loans attributed to
the Oklahoma Consumer Banking Division in 2008 increased $19 million or 7%
compared with 2007. Average deposits provided by the Oklahoma Consumer Banking
Division grew $136 million or 5% to $3.0 billion. Average demand deposits were
up $36 million or 10% over 2007. Interest bearing deposits increased $100
million or 4%, including a $229 million or 21% increase in interest bearing
transaction accounts and a $129 million or 9% decrease in time deposits. Other
operating revenue was up $1.5 million or 8% over 2007 largely from check card
revenue and overdraft fees. Operating expenses increased $1.5 million or 7% over
2007, including a $546 thousand or 7% increase in personnel expense and a $946
thousand or 7% increase in non-personnel expense. Net loans charged-off, which

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.
BOk Mortgage incurred a net loss of $3.5 million in the second quarter of 2008
compared to net income of $122 thousand in the second quarter of 2007. Changes
in the fair value of mortgage servicing rights, net of hedging activity, reduced
net income $3.8 million in 2008 and $379 thousand in 2007. In addition, an
increase in the provision for off-balance sheet credit risk on mortgage loans
sold with recourse reduced net income $2.1 million in the second quarter of
2008.

Mortgage banking activities consisted primarily 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. The Mortgage Banking Division
also holds a permanent portfolio of $447 million of residential mortgage loans
which generated net income of $473 thousand in the second quarter of 2008.

Loan Production Sector

Pre-tax loss from loan production totaled $1.8 million for the second quarter of
2008 compared with pre-tax income of $331 thousand for the second quarter of
2007. Loan production revenue totaled $3.9 million in second quarter of 2008,
including $5.9 million of capitalized mortgage servicing rights, partially
offset by net losses on mortgage loans sold. Loan production revenue totaled
$4.1 million in second quarter of 2007. Capitalized mortgage servicing rights
totaled $3.6 million for the second quarter of 2007. The average initial fair
value of servicing rights on mortgage loans funded was 1.61% for 2008 and 1.46%
for 2007. Mortgage loans funded totaled $362 million in second quarter of 2008
and $315 million in the second quarter of 2007. Approximately 60% and 17% of the
loans funded during the second quarter of 2008 were in Oklahoma and Texas,
respectively. The pipeline of mortgage loan applications totaled $517 million at
June 30, 2008, compared to $525 million at March 31, 2008 and $306 million at
June 30, 2007. Operating expenses, excluding direct loan production costs which
are recognized as part of the gain or loss on loans sold, totaled $6.8 million
in 2008 and $3.9 million in 2007. The increase in operating expenses was due to
a $3.4 million increase in provision for losses on loans sold with recourse.

Loan Servicing Sector

The loan servicing sector had a pre-tax loss of $5.1 million for the second
quarter of 2008 compared with a pre-tax loss of $552 thousand for the second
quarter of 2007. The increase in net loss from loan servicing during the second
quarter of 2008 was due to ineffectiveness of our economic hedging. We
recognized a net pre-tax loss of $6.3 million in the second quarter of 2008 and
a net pre-tax loss of $620 thousand in 2007 from changes in the value of
mortgage servicing rights and economic hedging activities. The fair value of
securities designated as an economic hedge decreased $5.5 million during the
second quarter of 2008, which was largely expected based on changes in market
interest rates for mortgage-backed securities. However, changes in mortgage
commitment rates, prepayment speed assumptions, discount
13

rates and other estimates of future activities decreased the fair value of
mortgage servicing rights recognized in earnings by $767 thousand in the second
quarter of 2008, which was unexpected. Factors which caused the fair value of
our servicing rights to not increase as expected included an increase in
prepayment speed of our servicing rights relative to national averages and a
decrease in short-term interest rates relative to mortgage commitment rates.
During the second quarter of 2007, economic hedge activity produced net losses
of $5.7 million, which largely offset that quarter's increase in the fair value
of servicing rights of $5.1 million.

Servicing revenue, including revenue on loans serviced for affiliates, totaled
$4.8 million in second quarter of 2008 compared to $4.4 million in the same
period of 2007. The average outstanding balance of loans serviced, including
loans serviced for affiliates, was $5.7 billion during the second quarter of
2008 compared to $5.2 billion during 2007. Servicing revenue per outstanding
loan principal was 34 basis points in 2008 compared with 34 basis points in
2007. Servicing costs totaled $1.8 million for the second quarter of 2008 and
$2.0 million for the second quarter of 2007. At June 30, 2008, the total number
of loans serviced by BOk Mortgage was 58,021. Serviced loans delinquent 90 days
or more or in process of foreclosure totaled 620 or 1.07%; 366 of these loans
are in Oklahoma, 71 are in Arkansas, 51 are in Kansas / Missouri and 38 are in
Texas.

The fair value of mortgage servicing rights decreased $3.4 million during the
second quarter of 2008 and $3.2 million during the second quarter of 2007 due to
actual runoff of the underlying loans serviced. This reduction in fair value is
included in mortgage banking costs in the Consolidated Statement of Earnings.

</TABLE>


BOK Financial designated a portion of its securities portfolio as an economic
hedge against the risk of changes in the fair value of its mortgage servicing
rights. These securities, which are identified as mortgage trading securities
are carried at fair value. Changes in fair value are recognized in earnings as
they occur. Additionally, mortgage-related 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. No special hedge accounting treatment is applicable to
either the mortgage servicing rights or the financial instruments designated as
an economic hedge.

Our 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.
14

At June 30, 2008, financial instruments with a fair value of $98.3 million and
an unrealized loss of $1.9 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, 2008, the
pre-tax results of this modeling on 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 $ 2,560 $ (3,724)
Fair value of hedging instruments (2,661) 2,671
----------------- ----------------
Net $ (101) $ (1,053)
----------------- ----------------


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 the fair value of our servicing rights $2.6 million while a
50 basis point decrease is expected to reduce the fair value $3.7 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. This is much less of a limit of the speed at which mortgage loans
may prepay in a declining rate environment.

Modeling changes in the value of 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 the assumed loan prepayment speeds
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 prepayments 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.

Wealth Management

BOK Financial provides a wide range of financial services through its wealth
management line of business, including trust and private financial services, and

management programs.

Wealth Management contributed net income of $9.6 million in the second quarter
of 2008. This compared to net income of $6.7 million in the second quarter of
2007. Growth in net income was due primarily to increased revenue from trading
and institutional securities sales.

Trust and private financial services provided $3.8 million of net income in the
second quarter of 2008, down $1.8 million from the second quarter of 2007. Trust
fees and commissions for the Wealth Management line of business totaled $18.1
million, up $1.2 million or 7% increase over last year. At June 30, 2008 and
2007, the Wealth Management line of business was responsible for trust assets
with aggregate market values of $31.4 billion and $30.8 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. We have sole or joint discretionary authority over $11.9
billion of trust assets at June 30, 2008 compared to $11.4 billion of trust
assets at June 30, 2007. The fair value of non-managed assets decreased $414
million to $11.8 billion at June 30, 2008. Assets held in safekeeping totaled
$7.7 billion at June 30, 2008. Operating expenses attributed to trust and
private financial services totaled $19.0 million for the second quarter of 2008
and $16.9 million for the second quarter of 2007. Personnel costs increased $1.1
million or 10% due primarily to staffing increases in the Arizona and Kansas
City markets. Non-personnel costs increased $962 thousand or 15% due to
increased legal, data processing and safekeeping costs.

Brokerage and trading activities provided $5.8 million of net income in 2008
compared to $1.1 million in 2007. Operating revenue increased $14.5 million due
to brokerage and trading revenue and fees earned on margin assets. Brokerage and
trading revenue increased $9.5 million due primarily to institutional securities
sales, customer derivative revenue and retail brokerage fees. In addition, fees
on margin assets were up $3.2 million, largely offset by a decrease
15

in net interest revenue for the cost to fund margin assets. Operating expenses,
which consist primarily of compensation expense increased $4.0 million or 34%.
Incentive compensation expense which is directly related to revenue growth was
up $4.0 million.

of 2008, up $248 thousand over the second quarter of 2007. The fair value of

Financial Condition

Securities

Investment securities, which consist primarily of Oklahoma municipal bonds, are
carried at cost and adjusted for amortization of premiums or accretion of
discounts. At June 30, 2008, investment securities were carried at $246 million
and had a fair value of $243 million. 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 totaled $6.0 billion at June 30, 2008, up
$337 million compared with March 31, 2008. Mortgage-backed securities
represented 97% of total available for sale securities.

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
20

making an investment and throughout the life of the security. The expected
duration of the mortgage-backed securities portfolio was approximately 2.9 years
at June 30, 2008. Management estimates that the expected duration would extend
to approximately 3.3 years assuming a 300 basis point immediate rate shock.
Mortgage-backed securities also have credit risk from delinquency or default of
the underlying loans. The Company mitigates this risk by primarily investing in
securities issued by U.S. government agencies. Principal and interest payments
on the underlying loans are either fully or partially guaranteed. Credit risk on
mortgage-backed securities originated by private issuers is mitigated by
investment in senior tranches with additional collateral support.

The Company has invested $46 million in variable rate perpetual preferred stocks
issued by seven major banks and brokerage houses. Although these issuers remain
rated investment grade by the major rating agencies and all scheduled dividend
payments have been made, the fair values of these stocks declined to $32 million
at as of June 30, 2008. Cumulative other-than-temporary impairment charges of
$14 million have been recognized. The fair value of these securities has
decreased an additional $5.1 million since June 30, 2008.

Net unrealized losses on available for sale securities totaled $91 million at
June 30, 2008 compared with net unrealized losses of $28 million at March 31,
2008. The aggregate gross amount of unrealized losses at June 30, 2008 totaled
$123 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. The portfolio
does not hold any securities backed by sub-prime mortgage loans, collateralized
debt obligations or collateralized loan obligations. Approximately $416 million
of Alt-A mortgage-backed securities were held at June 30, 2008 with a total
unrealized loss of $29 million. Approximately 82% 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. Approximately 86% of all of our Alt-A mortgage-backed securities
represent pools of fixed-rate mortgage loans. Management does not believe that
any of the unrealized losses were due to credit concerns. 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 were temporary.

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 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 to the Company.

Loans

The aggregate loan portfolio before allowance for loan losses totaled $12.6
billion at June 30, 2008, a $250 million or 8% annualized increase since March
31, 2008. Loan growth was broadly distributed among the various segments of the
portfolio and across all geographic markets.

The commercial loan portfolio increased $82 million during the second quarter of
2008 to $7.0 billion at June 30, 2008. Energy loans totaled $1.9 billion or 15%
of total loans. Outstanding energy loans decreased $72 million during the second
quarter of 2008, including a $46 million decrease in net outstanding balances
and a $26 million charge off of SemGroup loans. Approximately $1.6 billion of
energy loans was to oil and gas producers, down from $1.7 billion at March 31,
2008. 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 energy category
of our loan portfolio is distributed $1.0 billion in Oklahoma, $576 million in
Texas and $295 million in Colorado.

The services sector of the loan portfolio totaled $1.8 billion or 15% of total
loans and consists of a large number of loans to a variety of businesses,
including communications, gaming and transportation services. Approximately $1.3
billion of the services category is made up of loans with individual balances of
less than $10 million. Approximately $703 million of the outstanding balance of
services loans is attributed to Texas, $558 million to Oklahoma, $238 million to
New Mexico, $134 million to Arizona and $104 million to Colorado.

Other notable loan concentrations by primary industry of the borrowers are
presented in Table 17.

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 June 30, 2008, the
outstanding principal balance of these loans totaled $1.7 billion. Substantially
all of these loans are to borrowers with local market relationships. BOK
Financial serves as the agent lender in approximately 24% of its shared national
credits, based on dollars committed. 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 $2.8 billion or 22% of the loan portfolio
at June 30, 2008. Over the past five years, the percentage of commercial real
estate loans to our total loan portfolio ranged from 20% to 23%. The outstanding
balance of commercial real estate loans decreased $4 million or 1% annualized
from the previous quarter end. Construction and land development loans decreased
$45 million to $1.0 billion. Loans secured by multifamily
22

residential property increased $15 million and loans secured by other commercial
real estate increased $26 million.

Loans secured by land, residential lots and construction totaled $1.0 billion at
June 30, 2008. Approximately $265 million of these loans are attributed to the
Oklahoma market, $299 million to the Texas market, $180 million to the Colorado
market and $173 million to the Arizona market. Other commercial real estate
loans totaled $1.6 billion at June 30, 2008. The geographic distribution of
these loans included $547 million in Oklahoma, $484 million in Texas, $186
million in New Mexico, $162 million in Arizona and $87 million in Colorado. The
major components of other commercial real estate loans were retail facilities -
$378 million, office buildings - $423 million and industrial facilities - $180
million.

Residential mortgage loans, excluding loans held for sale, totaled $1.6 billion,
up $78 million since March 31, 2008. At June 30, 2008, residential mortgage
loans included $477 million of home equity loans, $520 million of loans held for
business relationship purposes, $447 million of adjustable rate mortgages and
$138 million of loans held for community development. Loans held for business
relationship purposes increased $57 million and adjustable rate mortgage loans
increased $22 million since March 31, 2008. We have no concentration in
sub-prime residential mortgage loans. Our portfolio of adjustable rate mortgage
loans is generally underwritten to prime standards and does not include loans
with initial rates that are below market.

At June 30, 2008, consumer loans included $735 million of indirect automobile
loans. Approximately $476 million of these loans were purchased from dealers in
Oklahoma and $181 million were purchased from dealers in Arkansas. The remaining
$78 million were purchased from dealers in Texas. Indirect automobile loans grew
$49 million since March 31, 2008, including $27 million in Texas, $15 million in
Oklahoma and $7 million in Arkansas. Approximately 7% of the outstanding balance
at June 30, 2008 is considered near-prime, which is defined as loans to
borrowers that had poor credit in the past but have re-established credit over a
period of time. We generally do not originate sub-prime indirect automobile
loans.

Loan Commitments

BOK Financial enters into certain off-balance sheet arrangements in the normal
course of business. These arrangements included loan commitments which totaled
$5.6 billion and standby letters of credit which totaled $626 million at June
30, 2008. 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
24

represent future cash requirements. Standby letters of credit issued on behalf
of customers whose loans are non-performing totaled approximately $14 million.

The Company also has off-balance sheet commitments for residential mortgage
loans sold with full or partial recourse. These loans consist of first lien,
fixed rate residential mortgage loans originated under various community
development programs and sold to U.S. government agencies. These loans were
underwritten to standards approved by the agencies, including full documentation
and focused primarily on first-time homebuyers. However, these loans have a
higher risk of delinquency and losses given default than traditional residential
mortgage loans. A separate recourse reserve is maintained as part of other
liabilities. At June 30, 2008, the principal balance of loans sold subject to
recourse obligations totaled $400 million. Approximately $15 million of these
loans were originated in 2008, $107 million in 2007 and $89 million in 2006.
Substantially all of these loans are to borrowers in our primary markets
including $281 million to borrowers in Oklahoma, $45 million to borrowers in
Arkansas, $23 million to borrowers in New Mexico, $19 million to borrowers in
the Kansas City area and $17 million to borrowers in Texas. These programs to
originate and sell mortgage loans with recourse were discontinued in the first
quarter of 2008.

We maintain a separate reserve for this off-balance commitment which totaled
$7.5 million at June 30, 2008. Approximately 2.12% of the loans sold with
recourse with an outstanding principal balance of $8.7 million were either
delinquent more than 90 days, in bankruptcy or in foreclosure. The provision for
credit losses on loans sold with recourse, which is included in mortgage banking
costs, was $2.9 million for the second quarter of 2008. Net losses charged
against the reserve totaled $1.3 million for the second quarter of 2008.

Derivatives with Credit Risk

The Company offers programs that permit its customers to hedge various risks,
including fluctuations in energy, cattle and other agricultural product 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.

Our customer energy hedging program is an integral part of our energy lending.
This program allows customers that either produce, purchase, store or transport
oil and natural gas to hedge their commodity price risk. We believe that a
customer's prudent hedging strategy reduces our overall credit exposure.
Generally, the fair value of customer contracts will increase or decrease in
direct relation to the fair value of their oil or natural gas reserves or their
obligations to acquire or deliver energy products. For example, the amount a
customer owes us to settle an energy contract may increase as market prices for
that commodity increase. The market price for the oil or natural gas owned by
that customer will also increase as the market prices for that commodity
increase. This relationship is one way our customer energy derivative contracts
remain well-secured as energy prices change.

The customer derivative 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 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
ratings, 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 occurs 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 customer or counterparty's
ability to provide margin collateral was impaired. At June 30, 2008, the fair
value of derivative contracts with SemGroup was reduced to approximately $37
million and a charge of $61 million was recognized because of their bankruptcy
filing on July 22, 2008 and the estimated value of the underlying collateral no
longer supported the contracts.

At June 30, 2008, the fair values of derivative contracts reported as assets
under these programs totaled $1.4 billion. This included energy contracts with
fair values of $1.3 billion, interest rate contracts with fair values of $73
million,
25

agricultural product contracts with fair values of $12 million and foreign
exchange contracts with fair values of $18 million. The aggregate net fair
values of derivative contracts reported as liabilities totaled $1.4 billion. As
of January 1, 2008, the Company adopted FASB Staff Position FIN 39-1 which
permits offsetting of cash collateral against the fair value of derivative
instruments executed with the same counterparty under a master netting
agreement. The aggregate net fair value of derivative liabilities at June 30,
2008 was $455 million after offsetting $990 million of cash collateral.

Approximately $1.3 billion or 98% of the fair value of asset energy contracts
was with customers. Approximately $989 million of the fair value of the asset
energy contracts are with energy producing customers. Credit risk of these
contracts is backed by energy production owned by these customers. Approximately
$252 million or 20% of the fair value of energy contracts, including $37 million
of contracts with SemGroup, are with customers which store or transport energy
products. Contracts with the five largest non-energy producing customers,
including SemGroup, total approximately $222 million. Credit risk of these
contracts is backed by physical product and other collateral, including cash
margin held by the Company and letters of credit issued by third-party banks for
the benefit of the Company. The remaining 2% of the fair value of asset energy
contracts was with dealer counterparties, consisting primarily of highly-rated
financial institutions and energy companies. The maximum net exposure to any
single customer totaled $129 million at June 30, 2008.

At July 31, 2008, the fair value of derivative contracts reported as assets
under our customer hedging programs totaled $748 million, down $631 million from
$1.4 billion at June 30, 2008 due primarily to decreases in energy prices and
contractual cash settlements. At July 31, 2008, the fair value of derivative
liabilities totaled $843 million, down $602 million from $1.4 billion at June
30, 2008. The decrease in the fair value of derivative liabilities reduced our
obligation to place cash margin collateral with our counterparties. Cash margin
collateral placed by us to secure our obligations to dealer counterparties
decreased $564 million during July to $426 million at July 31, 2008. The loss in
fair value of SemGroup contracts, net of gains on amounts owed to energy dealers
on related contracts, decreased $14.7 million during July 2008 due to decreases
in energy prices. This reduction in net loss increases brokerage and trading
revenue in the third quarter. However, the net loss on SemGroup contracts is
subject to further changes during the third quarter until the settlement prices
on open contracts become fixed. At July 31, 2008, approximately $160 million of
the fair value of energy contracts are with customers which store or transport
energy products. Contracts with the five largest non-energy producing customers,
including SemGroup, total approximately $151 million. The maximum net exposure
to any single customer totaled $95 million at July 31, 2008.

Summary of Loan Loss Experience

BOK Financial maintains separate reserves for loan losses and reserves for
off-balance sheet credit risk. Combined, these reserves totaled $177 million or
1.41% of outstanding loans at June 30, 2008 and $156 million or 1.27% of
outstanding loans at March 31, 2008.

The reserve for loan losses, which is available to absorb losses inherent in the
loan portfolio, totaled $154 million at June 30, 2008 compared with $137 million
at March 31, 2008. These amounts represented 1.23% and 1.11% of outstanding
loans, excluding loans held for sale, at June 30, 2008 and March 31, 2008,
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
96% of outstanding balance of nonperforming loans at June 30, 2008 compared to
123% at March 31, 2008. Net loans charged off during the second quarter of 2008
totaled $39.0 million compared to $8.9 million in the previous quarter and $5.8
million in the second quarter of 2007. Charge-offs of SemGroup loans were $26.0
million. The ratio of net loans charged off to average outstanding loans was
1.26% for the second quarter of 2008 compared with 0.29% in first quarter of
2008. Net commercial loan charge-offs, excluding SemGroup and net commercial
real estate loan charge-offs increased $2.9 million and $924 thousand,
respectively, compared with the previous quarter. Subsequent to June 30, 2008,
the Company recovered $11.1 million on two loans charged off in previous years.
These recoveries will increase the allowance for loan losses in the third
quarter of 2008.

Consumer loan net charge-offs, which includes indirect auto loan and deposit
account overdraft losses, totaled $2.9 million for the second quarter of 2008,
up $168 thousand over the previous quarter. Net charge-offs of indirect auto
loans totaled $1.7 million for the second quarter of 2008 and $1.6 million for
the first quarter of 2008. Net indirect auto loans charged off were $950
thousand in the Oklahoma market, $692 thousand in the Arkansas market and $56
thousand in the Texas market. Approximately 1.95% of the indirect automobile
loan portfolio is past due 30 days or more, including 2.03% in Oklahoma, 2.03%
in Arkansas and 1.27% in Texas. At March 31, 2008, approximately 1.96% of the
indirect automobile loan portfolio was past due 30 days or more.

The Company considers the 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 19
presents the trend of reserves for off-balance sheet credit losses and the
relationship between the reserve and loan commitments. The
26

relationship between the combined reserve for credit losses and outstanding
loans is also presented for comparison with peer banks and others who have not
adopted the 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.

Specific impairment reserves are determined through evaluation of estimated
future cash flows and collateral value. At June 30, 2008, specific impairment
reserves totaled $11.0 million on total impaired loans of $139 million. Specific
impairment reserves were $5.2 million on total impaired loans of $90 million at
March 31, 2008.

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 range of
nonspecific reserves for general economic factors includes their effect on our
commercial, residential mortgage and consumer loan portfolios. Nonspecific
reserves attributed to general economic conditions increased in the second
quarter of 2008. Weakness in the economy became more apparent due to rising
materials, food and energy prices along with continued weakness in residential
real estate markets.

The provision for credit losses totaled $59.3 million for the second quarter of
2008, $17.6 million for the first quarter of 2008 and $7.8 million for the
second quarter of 2007. The second quarter of 2008 provision included $26.3
million directly related to the Company's loans and loan commitments to
SemGroup. Other factors considered in determining
27

the provision for credit losses included trends in net losses and nonperforming
loans, the application of statistical migration factors to loan growth and
concentrations in commercial real estate and residential homebuilder loans. In
addition, the outstanding balances of criticized and classified loans and
potential problem loans increased.


Nonperforming Assets

Information regarding nonperforming assets, which totaled $181 million at June
30, 2008 and $126 million at March 31, 2008, is presented in Table 20.
Nonperforming assets included nonaccrual and renegotiated loans and excluded
loans 90 days or more past due but still accruing interest. Total nonperforming
assets were 1.45% of period-end loans and repossessed assets at June 30, 2008,
up from 1.02% at March 31, 2008. At June 30, 2008, nonperforming assets excluded
$47 million of amounts due from SemGroup under derivative contracts and
outstanding letters of credit that have not been funded. Amounts due under the
derivative contracts will be reclassified as loans and reported as nonperforming
if not paid on their contractual settlement dates, primarily in the third
quarter of 2008. If all amounts due from SemGroup had been reported as loans at
June 30, 2008, nonperforming assets and nonperforming assets as a percent of
period-end loans and repossessed assets would have been $229 million and 1.82%,
respectively.

Nonaccrual loans totaled $149 million at June 30, 2008 and $99 million at March
31, 2008. Newly identified nonaccrual loans totaled $100 million during the
second quarter, including $38 million of loans to SemGroup. Newly identified
nonaccrual loans also included $24 million of loans to residential homebuilders
and $12 million to a mortgage lender. Nonaccrual loans decreased $33 million for
loans charged off and foreclosed, including $26 million of loans to SemGroup,
and $16 million for cash payments received. The net increase in nonaccrual loans
to SemGroup during the second quarter of 2008 totaled $12 million. Approximately
$12 million of nonaccrual loans are subject to the First United Bank sellers'
escrow.

Nonaccrual commercial loans totaled $70 million at June 30, 2008 and $42 million
at March 31, 2008. In addition to $12 million of nonaccrual loans to SemGroup
and a $12 million nonaccrual loan to a mortgage lender, nonaccrual commercial
loans consisted primarily of loans in the services and manufacturing sectors of
the portfolio. None of the other nonaccrual commercial loans exceeded $10
million. Approximately $40 million of nonaccrual commercial loans are to
borrowers in the Oklahoma market, $6 million are in the Texas market, $17
million are in the Colorado market and $4 million are in the New Mexico market.

Nonaccrual commercial real estate loans totaled $60 million at June 30, 2008 and
$40 million at March 31, 2008. Approximately $45 million are loans secured by
land and residential lots and construction, including $30 million in Arizona ($7
million in Tucson and $23 million in Phoenix), $6 million in Texas and $5
million in Colorado. Other significant nonaccrual commercial real estate loans
included $5.3 million of retail facilities in New Mexico.

In addition to nonaccrual loans, nonperforming assets included $12 million of
renegotiated loans and $21 million of real estate and other repossessed assets.
Renegotiated loans consisted of residential mortgage loans and indirect
automobile loans whose original terms have been modified. Approximately $8.6
million of renegotiated loans are residential mortgage loans guaranteed by
agencies of the U.S. government. Real estate and other repossessed assets
included $8 million of single family residential properties, $5 million of land
and single family lots and construction, $3 million of manufacturing facilities
and $2 million of automobiles. The geographic distribution of real estate and
other repossessed assets included $6 million in Oklahoma, $3 million in New
Mexico, $3 million in Colorado, $4 million in Arkansas, $3 million in Texas and
$2 million in Arizona. Approximately $1.7 million of real estate and other
repossessed assets are subject to the First United Bank sellers' escrow.

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 concern
as to the borrowers' ability to comply with current repayment terms. These
potential problem loans totaled $40 million at June 30, 2008 and $31 million at
March 31, 2008. The current composition of potential problem loans by primary
industry included real estate - $16 million, healthcare - $9 million and
services - $10 million. Potential problem real estate loans consisted primarily
of loans to residential builders in the Arizona market of $12 million.

Deposits

Deposit accounts represent our largest funding source. Average deposits
represented approximately 62% of total liabilities and capital for the second
quarter of 2008, down from 67% for the second quarter of 2007 and 64% for the
first quarter of 2008. The decrease in average deposits relative to other
funding sources is due largely to the structuring of our balance sheet to be
relatively neutral to changes in interest rates. Other borrowed funds increased
to fund an increase in average securities to implement this interest rate risk
management strategy and an increase in margin assets. In addition, competition
has increased the cost of deposits compared to other funding sources in many of
our markets.

Average deposits totaled $13.3 billion for the second quarter of 2008, a $915
million or 7% increase over the second quarter of 2007. Average deposits
increased $198 million or 6% annualized compared with the first quarter of 2008.

Interest-bearing transaction deposit accounts continued to grow in the second
quarter of 2008, up $1.3 billion or 20% over the second quarter of 2007 and $244
million or 13% annualized over the first quarter of 2008. Time deposits
decreased $431 million or 10% from the second quarter of 2007 and $149 million
or 14% annualized from the first quarter of 2008. Average demand deposits
increased $41 million or 3% over the second quarter of 2007 and $100 million
over the first quarter of 2008.

Core deposits, which we define as deposits of less than $100,000, excluding
public funds and brokered deposits, averaged $6.5 billion for the second quarter
of 2008, $6.4 billion for the second quarter of 2007 and $6.5 billion for the
first quarter of 2008. Accounts with balances in excess of $100,000 averaged
$5.5 billion for the second quarter of 2008, $4.7 billion for the second quarter
of 2007 and $5.4 billion, for the first quarter of 2008.

Average commercial banking deposits totaled $4.5 billion for the second quarter
of 2008, up $297 million or 7% over the second quarter of last year. The average
balance of commercial banking deposits for the second quarter of 2007 was $4.3
billion. Commercial deposit growth was primarily centered in Oklahoma and Texas.
Consumer deposits averaged $5.6 billion for the second quarter of 2008, up $312
million or 6% over 2007. Average consumer deposit account balances increased
$136 million or 5% in Oklahoma and $169 million or 18% in Texas, including
deposits acquired with Worth National Bank in the second quarter of 2007. Wealth
management deposit accounts averaged $2.0 billion for the second quarter of
2008, a $416 million or 27% increase over 2007. Approximately $294 million of
the increase was in the Oklahoma market. The remaining increase was primarily in
Colorado.

The distribution of deposit accounts among our principal markets is shown in
Table 21.

Borrowings and Capital

At June 30, 2008, BOK Financial (parent company) had a $188 million unsecured
revolving line of credit with certain commercial banks that matures in December
2010. The outstanding principal balance of this credit agreement was $50
million. Interest is based upon a base rate or LIBOR plus a defined margin
determined by the Company's credit rating. This margin ranged from 0.375% to
1.125% or a base rate. At June 30, 2008, the margin applicable to borrowings
against this line was 0.375%. The base rate was defined as the greater of the
daily federal funds rate plus 0.5% or the SunTrust Bank prime rate. Interest was
generally paid monthly. Facility fees were 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 included 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 required BOK Financial and
subsidiary banks to maintain minimum capital levels and established maximum
nonperforming asset levels. BOK Financial met all of the restrictive covenants
at June 30, 2008. Subsequent to June 30, all amounts due under this credit
agreement were paid and the agreement was terminated at the request of the
Company.

On July 21, 2008, the Company entered into a $188 million, unsecured revolving
credit agreement with George B. Kaiser, its Chairman and principal shareholder.
Interest on the outstanding balance is based on one-month LIBOR plus 125 basis
points and is payable quarterly. Additional interest in the form of a facility
fee is paid quarterly on the unused portion of the commitment at 25 basis
points. This agreement has no restrictive covenants, which provides greater
flexibility to fund the needs of BOK Financial and its subsidiaries.

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 $67 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 $18 million
under this policy.

Equity capital for BOK Financial decreased $50.2 million to $1.9 billion during
the second quarter of 2008. Cumulative retained earnings decreased $16.4 million
due to a $1.2 million net loss and $15.2 million of cash dividends paid.
Accumulated other comprehensive losses increased $38.7 million during the second
quarter of 2008 due primarily to an increase in net unrealized losses on
available for sale securities. Employee stock option transactions increased
equity capital $4.8 million.

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 program may be suspended or discontinued
at any time without prior notice. Since this program began, 709,073 shares have
been repurchased by the Company for $35.4 million. No shares were repurchased in
the second quarter of 2008. In addition, the Company initiated a 10b5-1 stock
repurchase plan in the second quarter of 2008. This plan has subsequently been
terminated.

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 a 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
the Company's banking subsidiaries exceeded the regulatory definitions of well
capitalized at June 30, 2008, except Bank of Arizona. The total capital ratio
for Bank of Arizona at June 30, 2008 was 9.83%. Subsequently, $4 million of
additional capital was contributed, which brought its total capital ratio to
11.48%. The capital ratios for BOK Financial on a consolidated basis are
presented in Table 22.

Off-Balance Sheet Arrangements

During the third quarter of 2007, Bank of Oklahoma agreed to guarantee rents
totaling $28.4 million over 10 years to the City of Tulsa ("City") as owner of a
building immediately adjacent to the bank's main office. These rents are due for
space rented by third-party tenants in the building as of the date of the
agreement. All guaranteed space has been rented since the date of the agreement.
At June 30, 2008, rent payments of $26.7 million remain subject to this guaranty
agreement. In return for this guarantee, Bank of Oklahoma will receive 80% of
net rent as defined in an agreement with the City over the next 10 years from
space in the same building that was vacant as of the date of the agreement. The
maximum amount that Bank of Oklahoma may receive under this agreement is $4.5
million. The fair value of this agreement at inception was zero and no asset or
liability is currently recognized in the Company's financial statements.

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. Market risk excludes changes in fair value due to credit of the
individual issuers of financial instruments.

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 and agricultural
product 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 un-pledged
assets, among other things. Compliance with these guidelines is reviewed
monthly.

Interest Rate Risk - Other than Trading

As previously noted in the Net Interest Revenue section of this report,
management has implemented strategies to manage the Company's balance sheet to
be relatively neutral to changes in interest rates over a twelve month period.
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 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 assumes a
sustained parallel 200 basis point increase and the second assumes a sustained
parallel 100 basis point decrease in interest rates. Management historically
evaluated interest rate sensitivity for a sustained 200 basis point decrease in
interest rates. However, the results of a 200 basis point decrease in interest
rates in the current low-rate environment are not meaningful. 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,
33

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 23 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
re-pricing 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. 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, 2008, the VAR was $1.2 million. The
greatest value at risk during the second quarter of 2008 was $1.8 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
2007 Form 10-K filed with the Securities and Exchange Commission, which contains
audited financial statements. Amounts presented as of December 31, 2007 have
been derived from BOK Financial's 2007 Form 10-K.

Newly Adopted and Pending Accounting Policies

The Company adopted Statement of Financial Accounting Standards No. 159, Fair
Value Option ("FAS 159") effective January 1, 2008. FAS 159 provides an option
to measure eligible financial assets and financial liabilities at fair value.
Certain certificates of deposit that were either currently designated as hedged
or had previously been designated as hedged, but no longer met the correlation
requirements of Statement of Financial Accounting Standards No. 133 were
designated as being reported at fair value. Adoption of FAS 159 increased
opening retained earnings for the first quarter of 2008 by $62 thousand.
Interest expense on certificates of deposit carried at fair value is based on
the instruments' contractual interest rates and outstanding principal balances.

As of January 1, 2008, the Company adopted Financial Accounting Standards Board
Staff Position FIN 39-1, which permits offsetting of cash collateral against the
fair value of derivative instruments executed with the same counterparty under a
master netting agreement. The total amount of derivative assets and liabilities
at June 30, 2008 was reduced by $10 million and $990 million, respectively, of
cash collateral.

Statement of Financial Accounting Standards No. 160, "Noncontrolling Interest in
Consolidated Financial Statements, an amendment of ARB Statement No. 51," ("FAS
160") amends Accounting Research Bulletin (ARB) No. 51, "Consolidated Financial
Statements," to establish accounting and reporting standards for the
non-controlling interest in a subsidiary and for the deconsolidation of a
subsidiary. FAS 160 clarifies that a non-controlling interest in a subsidiary,
which is sometimes referred to as minority interest, is an ownership interest in
the consolidated entity that should be reported as a component of equity in the
consolidated financial statements. Among other requirements, FAS 160 requires
consolidated net income to be reported at amounts that include the amounts
attributable to both the parent and the non-controlling interest. It also
requires disclosure, on the face of the consolidated income statement, of the
amounts of consolidated net income attributable to the parent and to the
non-controlling interest. FAS 160 is effective for the Company on January 1,
2009 and is not expected to have a significant impact on the Company's financial
statements.

Statement of Financial Accounting Standards No. 161, "Disclosures About
Derivative Instruments and Hedging Activities, an Amendment of FASB Statement
No. 133," ("FAS 161") amends and expands the disclosure requirements of FAS 133,
"Accounting for Derivative Instruments and Hedging Activities," to provide
greater transparency about (i) how and why an entity uses derivative
instruments, (ii) how derivative instruments and related hedge items are
accounted for under SFAS 133 and its related interpretations, and (iii) how
derivative instruments and related hedged items affect an entity's financial
position, results of operations and cash flows. To meet those objectives, FAS
161 requires qualitative disclosures about objectives and strategies for using
derivatives, quantitative disclosures about fair value amounts of gains and
losses on derivative instruments and disclosures about credit-risk-related
contingent features in derivative agreements. FAS 161 is effective for the
Company on January 1, 2009 and is not expected to have a significant impact on
the Company's financial statements.

(2) Fair Value Measurements

Fair value measurements as of June 30, 2008 are as follows (in thousands):

</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 4, Mortgage Banking
Activities.
(2) The fair value of derivative contracts with SemGroup, LP was based
largely on significant unobservable inputs. On July 22, 2008, SemGroup
and 24 related entities filed for bankruptcy protection. BOK Financial
assessed a range of values for derivative contracts with SemGroup using
information currently available, including information provided by a
nationally recognized financial advisor to SemGroup. The range
considered both the value of SemGroup as a reorganized entity (going
concern value) and its liquidation value. The fair value of derivative
contracts was based on the lower end of the range of values. The fair
value of derivative contracts with SemGroup totaled $88.2 million at
March 31, 2008 and $97.3 million at June 30, 2008 based on significant
observable inputs. At June 30, 2008, the fair value of these contracts
was written down by $60.7 million to $36.6 million based on significant
unobservable inputs.

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 significant fair value measurements of significant assets or liabilities
measured on a non-recurring basis were made during the first half of 2008.
Assets measured on a non-recurring basis include pension plan assets, which are
based on quoted prices in active markets for identical instruments, real
property and other assets acquired to satisfy loans, which are based primarily
on comparisons of completed sales of similar assets, and goodwill, which is
based on significant unobservable inputs.

Certain certificates of deposit were designated as carried at fair value as
permitted by FAS 159. These certificates have been converted from fixed interest
rates to variable interest rates based on LIBOR with interest rate swaps. The
fair value election for these liabilities better represents the economic effect
of these instruments on the Company. At June 30, 2008, the fair value and
contractual principal amount of these certificates was $204 million and $205
million, respectively. Change in the fair value of these certificates of deposit
resulted in an unrealized gain during the second quarter and first half of 2008
of $2.2 million and $601 thousand, respectively, which is included in Gain
(Loss) on Derivatives, net on the Consolidated Statement of Earnings.

(10) Contingent Liabilities

In September 2006, BISYS settled the SEC's two-year investigation of BISYS Fund
Services Ohio, Inc. ("BISYS") marketing assistance agreements with 27 different
families of mutual funds, including a BISYS marketing arrangement with AXIA
which had been terminated effective January 1, 2004. In the SEC settlement,
BISYS consented to an order in which the SEC determined that BISYS had
"willfully aided and abetted and caused" the 27 investment advisors to (i)
violate provisions of the Investment Advisors Act of 1940 that prohibit
fraudulent conduct; (ii) 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 (iii) 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 was one
of the 27 advisors and the AP Funds one of the 27 mutual fund families to which
the SEC referred in its BISYS Order. On October 10, 2006, the Examinations
Division of the Securities and Exchange Commission (the "SEC") conducted an
examination of AXIA. The examination was concluded in July 2007 with no action
taken by the Examinations Division. In August 2007, AXIA settled all claims
relating to the BISYS marketing arrangements with the AP Funds for $2.2 million
and the AP Funds regard the matter as fully concluded. The settlement with the
AP Funds is not binding on the SEC.

On April 7, 2008, AXIA and its parent, BOK, received a Wells notice from the
regional office of the SEC in Los Angeles indicating that the staff is
considering recommending that the SEC bring a civil injunctive action against
AXIA and BOK for violations of Section 17(a) of the Securities Act of 1955,
Section 10(b) of the Securities Exchange Act of 1934, Sections 206(1) and (2) of
the Investment Advisors Act of 1940, and Sections 12(b) and 34(b) of the
Investment Company Act of 1940. BOK and AXIA have been cooperating fully with
the SEC in connection with these matters that arose prior to December 31, 2003.
BOK and AXIA are not bound by the SEC BISYS Order and disagree with the SEC
position as it relates to BOK and AXIA. On May 27, 2008, BOK and AXIA responded
to the Wells notice denying the SEC position. On June 26, 2008, BOK and AXIA
representatives met with SEC Staff. Nothing further has occurred as of this
time.

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.

During the fourth quarter of 2007, Visa announced that it had recognized
liabilities related to antitrust litigation with American Express and Discover
and that it was subject to other litigation. As a member of Visa, BOK Financial
is obligated for a proportionate share of losses incurred by Visa. A contingent
liability was recognized for the Company's share of Visa's litigation
liabilities.

During the first quarter of 2008, Visa completed its initial public offering and
funded a $3.0 billion escrow account for litigation claims including claims by
American Express and Discover. BOK Financial recognized a receivable for its
proportionate share of this escrow account, which equals the contingent
liability previously recognized.

In addition, during the first quarter of 2008 BOK Financial received 410,562
Visa Class B shares. A partial redemption of Class B shares was completed and
the Company received $6.8 million in cash in exchange for 158,725 Class B
shares. The remaining 251,837 Class B shares are convertible into Visa Class A
shares at the later of three years after the date of Visa's initial public
offering or the final settlement of all covered litigation. The current exchange
rate is approximately 0.71 Class A share for each Class B share. However, the
Company's Class B shares may be diluted in the future if the escrow fund is not
adequate to cover future covered litigation costs. Therefore, under currently
issued accounting guidance no value has been currently assigned to the Class B
shares and no value may be assigned until the Class B shares are converted into
a known number of Class A shares.

(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, 2008, outstanding commitments and letters of credit were as
follows (in thousands):

June 30,
2008
--------------
Commitments to extend credit $ 5,600,714
