Operations

Performance Summary

BOK Financial Corporation reported earnings of $56.7 million or $0.84 per
diluted share for the third quarter of 2008. The Company reported a net loss of
$1.2 million or $.02 per diluted share for the second quarter of 2008 and net
income of $59.8 million or $0.89 per diluted share for the third quarter of
2007.

Year-to-date net income totaled $117.8 million or $1.74 per diluted share for
the nine months ended September 30, 2008 and $166.5 million or $2.46 per diluted
share for the nine months ended September 30, 2007.

As disclosed in the previous quarter's Form 10-Q, 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 for
the second quarter of 2008 by approximately $57.0 million or $0.84 per diluted
share. A $19.4 million increase in the fair value of derivative contracts
related to SemGroup, partially offset by a $12.7 million write off of derivative
contracts with Lehman Brothers increased net income for the third quarter of
2008 by $4.5 million or $0.07 per diluted share.

Highlights of the third quarter of 2008 included:

o Net interest revenue totaled $164.3 million, up $5.4 million over the
second quarter of 2008 and $24.9 million over the third quarter of 2007.
Net interest margin was 3.48% for the third quarter of 2008, 3.44% for the
second quarter of 2008 and 3.27% for the third quarter of 2007. Growth in
net interest revenue and net interest margin was due largely to increased
earning assets and widening spreads.

o Fees and commission revenue totaled $126.7 million for the third quarter of
2008, $63.6 million for the second quarter of 2008 and $103.7 million for
the third quarter of 2007. Fees and commissions grew $16.9 million or 16%
over the third quarter of 2007, excluding SemGroup and Lehman related
items, due largely to brokerage and trading revenue. Fees and commissions
decreased $2.4 million, excluding SemGroup and Lehman related items, from
the second quarter of 2008.

o Combined reserves for credit losses totaled $209 million or 1.65% of
outstanding loans at September 30, 2008, up from $177 million or 1.41% of
outstanding loans at June 30, 2008. Net loans charged off and provision for
credit losses were $20.2 million and $52.7 million, respectively, for the
third quarter of 2008. Net loans charged off and provision for credit
losses were $39.0 million and $59.3 million, respectively, for the second
quarter of 2008 and $4.9 million and $7.2 million, respectively, for the
third quarter of 2007.
3

o Non-performing assets totaled $252 million or 1.98% of outstanding loans
and repossessed assets at September 30, 2008, up from $181 million or 1.45%
of outstanding loans and repossessed assets at June 30, 2008. The increase
in non-performing assets included an expected $36.0 million of unpaid
amounts due from SemGroup in settlement of funded letters of credit and
derivative contracts which terminated during the third quarter.

o The Company maintained strong Tier 1 and tangible capital ratios of 9.25%
and 7.16%, respectively, at September 30, 2008. Tier 1 and tangible capital
ratios were 8.69% and 7.15%, respectively, at June 30, 2008. The Company
paid a dividend of $15.2 million or $0.225 per common share during the
third quarter of 2008.

o On October 28, 2008, the Company's board of directors declared a dividend
of $0.225 per common share payable on December 2, 2008 to shareholders of
record as of November 14, 2008.


Results of Operations

Net Interest Revenue and Net Interest Margin

Net interest revenue totaled $164.3 million for the third quarter of 2008, up
$5.4 million over the second quarter of 2008 and $24.9 million over the third
quarter of 2007. Average earning assets for the third quarter of 2008 increased
$1.7 billion over the third quarter of 2007. Average loans, excluding
residential mortgage loans held for sale, increased $980 million and average
securities increased $745 million. Growth in the securities portfolio generally
consisted of fixed-rate mortgage backed securities issued by FNMA and FHLMC.
These securities were purchased to take advantage of widening spreads caused by
disruptions in the mortgage-backed securities market.

Growth in average earning assets was funded primarily by a $1.3 billion increase
in average deposits. Average deposits were up 10% over the third quarter of
2007. Interest-bearing transaction accounts increased $973 million and demand
deposit accounts increased $349 million. In addition to deposit growth, average
funds purchased and other borrowings increased $458 million and $509 million,
respectively.

Funds generated by growth in deposits and borrowings were also used to fund a
$437 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 reductions of the derivative liabilities they
secure on the Company's consolidated balance sheet.

Net interest margin was 3.48% for the third quarter of 2008, 3.44% for the
second quarter of 2008 and 3.27% for the third quarter of 2007. Growth in net
interest margin compared with the third quarter of 2007 was due primarily to a
widening of the spread between LIBOR and the federal funds rate. 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.

The tax-equivalent yield on earning assets was 5.55% for the third quarter of
2008, down 144 basis points from the third quarter of 2007. Loan yields
decreased 219 basis points to 5.69%. Securities portfolio yield was 5.15%, up 20
basis points over the third quarter of 2007. Our securities re-price as cash
flow received is reinvested at current market rates. The resulting change in
yield on the securities portfolio occurs more slowly and may not move in the
same direction as changes in market rates.

The cost of interest-bearing liabilities was 2.41% for the third quarter of
2008, down 198 basis points from the third quarter of 2007. The cost of interest
bearing deposits decreased 171 basis points to 2.39% and the cost of funds
purchased and other borrowings decreased 288 basis points to 2.16%. 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 34 basis points in the
third quarter of 2008 compared with 67 basis points in the third quarter of 2007
and 30 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 changes in 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 two-thirds 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
4

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 $685 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 increased $22.9 million compared with the third quarter
of 2007. Fees and commissions revenue was up $22.9 million, including a $19.4
million increase in the fair value of derivative contracts related to SemGroup
partially offset by charges of $12.7 million from the Lehman Brothers
bankruptcy. The SemGroup-related contracts were with other counterparties to
offset our exposure to commodity price changes.

Diversified sources of fees and commission 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 revenue was $30.8 million for the third quarter of 2008,
up $15.3 million over the third quarter of 2007. Excluding the net effect of
transactions related to SemGroup and Lehman Brothers from the third quarters of
2008 and 2007, brokerage and trading revenue increased $9.3 million or 62%.
Revenue from trading and institutional securities sales totaled $10.6 million
for the third quarter of 2008, up $5.2 million over the third quarter of 2007.
Customer hedging revenue, excluding SemGroup and Lehman Brothers, totaled $7.0
million for the third quarter of 2008, up $3.3 million over the third quarter of
2007. The Company is currently modifying the terms of its customer hedging
program, which may affect future revenue.

Brokerage and trading revenue, excluding SemGroup and Lehman Brothers, increased
$884 thousand compared to the second quarter of 2008. Revenue from trading and
institutional securities sales decreased $1.0 million and customer hedging
revenue increased $3.0 million. Retail brokerage fees totaled $5.0 million for
the third quarter of 2008, down $1.2 million from the previous quarter.

Transaction card revenue totaled $25.6 million for the third quarter of 2008, up
$1.8 million or 8% over the third quarter of 2007. ATM network revenue increased
$1.0 million or 10% and check card revenue increased $971 thousand or 16%.
Merchant discount fees were down $182 thousand or 3%. Transaction card revenue
decreased $154 thousand or 2% annualized compared with the second quarter of
2008. Check card revenue was down $113 thousand or 6% annualized due to a
general slow-down of consumer spending.

Trust fees and commissions totaled $20.1 million for the third quarter of 2008,
an increase of $467 thousand or 2% over the third quarter of 2007. The fair
value of all trust assets which is the basis for a significant portion of trust
revenue totaled $33.2 billion at September 30, 2008 and $34.9 billion at
September 30, 2007. The decrease in the fair value of trust assets primarily
affected personal trust management fees and mutual fund fees. Personal trust
management fees, which provide 29% of total trust fees and commissions decreased
$101 thousand or 2% compared with 2007. Net fees from mutual fund advisory and
administrative services which provide 20% of total trust fees and commissions
decreased $150 thousand or 4%. Revenue from management of oil and gas properties
increased $1.0 million compared with the third quarter of 2007 due to higher
energy prices. Employee benefit plan management fees, which provide 18% of total
trust fees and commissions, increased $462 thousand or 15%.

Trust fees and commissions decreased $841 thousand or 16% annualized compared
with the second quarter of 2008. The fair value of all trust assets managed
totaled $34.4 billion at June 30, 2008 or 3% more than the fair value of all
trust assets at September 30, 2008 due to market conditions. Personal trust
revenue decreased $1.0 million. Net fees from mutual fund advisory and
administrative services decreased $463 thousand.

Deposit service charges and fees totaled $30.4 million for the third quarter of
2008, up $2.5 million or 9% over the third quarter of 2007. Overdraft fees grew
$1.2 million or 6%. Service charges on retail accounts decreased $51 thousand or
4% due to continued migration to service charge free checking products.
Commercial deposit account fees were up $1.4 million or 19% over the same period
of 2007 due to a decrease in earnings credit available to commercial deposit
customers and an increase in service charges for 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. Deposit service charges increased $205 thousand or 3% annualized compared
with the second quarter of 2008. Overdraft fees were up $911 thousand.
Commercial deposit account fees were down $684 thousand.

Mortgage banking revenue was up $421 thousand or 7% compared with 2007.
Servicing revenue totaled $4.4 million, up $196 thousand or 5%. The outstanding
principal balance of mortgage loans serviced for others totaled $5.1 billion at
September 30, 2008 and $4.8 billion at September 30, 2007. Net gains on mortgage
loans sold totaled $1.8 million, up $223 thousand over the third quarter of
2007. Mortgage loans originated for sale in the secondary market totaled $258
million for the third quarter of 2008, up 5% over the same period in 2007.
6

Margin asset fees totaled $1.9 million in the third quarter of 2008 and $1.1
million in the third quarter of 2007. Margin assets which are placed by the
Company to secure its obligations under customer derivatives programs averaged
$532 million for the third quarter of 2008, compared with $95 million for the
third 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.

BOK Financial recognized net gains of $2.1 million on securities for the third
quarter of 2008, net gains on securities of $4.7 million for the third quarter
of 2007 and net losses on securities of $5.2 million for the second 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.

Net gains on derivatives totaled $4.4 million for the third quarter of 2008 and
$865 thousand for the third 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 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. The fair value of these swaps generally
decreases 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. The fair value of these fixed-rate certificates of deposit
generally increases as interest rates fall.

Other Operating Expense

Other operating expense for the third quarter of 2008 totaled $164.3 million, up
$13.3 million or 9% over the third quarter of 2007. Personnel costs increased
$1.7 million or 2%. Non-personnel expenses increased $11.5 million or 18% due
largely to higher deposit insurance costs and losses on mortgage loans sold with
recourse. In addition, the Company accrued $1.7 million in the third quarter of
2008 to recognize its additional contingent obligation to support Visa's
antitrust litigation costs. This amount is expected to reverse in future periods
when Visa issues additional common shares to provide additional funds to its
litigation escrow account.

Personnel expense

Personnel expense totaled $87.5 million for the third quarter of 2008 and $85.8
million for the third quarter of 2007, including personnel expense of $2.5
million for net workforce reduction costs. Regular compensation, which consists
of salaries and wages, overtime pay and temporary personnel costs totaled $55.4
million, up $1.8 million or 3% over the third 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
down 4% over the third quarter of last year.

</TABLE>

Incentive compensation increased $2.3 million or 13% to $20.2 million compared
to the third quarter of 2007. Expense for cash-based incentive compensation
plans increased $4.6 million or 29%. 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 third quarter of 2007 included a
8

$2.8 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 $2.7 million compared with the
second quarter of 2008. This decrease reflected changes in the market value of
BOK Financial common stock and other investments. The market value of BOK
Financial common stock decreased $5.04 per share in the third quarter of 2008
and decreased $2.01 per share in the third quarter of 2007. Compensation expense
for equity awards increased $371 thousand or 30% compared with the third 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 $11.9 million, a $120 thousand or 1% increase
over the third quarter of 2007. Medical insurance costs were down $353 thousand
or 8%. The Company self-insures a portion of its employee health care coverage.

Personnel expense decreased $2.0 million compared with the second quarter of
2008 due to lower incentive compensation and employee benefit expenses.
Stock-based incentive compensation decreased $2.7 million due to lower cost of
liability awards. Employee benefit expense decreased $1.4 million due primarily
to seasonally lower payroll tax expense.

Data processing and communications expense

Data processing and communications expense totaled $19.9 million, up $1.6
million or 9% over the third quarter of 2007. This expense consists of two broad
categories, data processing systems and transaction card processing. Data
processing systems costs increased $1.5 million or 14% due to growth in
processing volumes. Transaction card processing costs increased $145 thousand or
2% due to growth in processing volume.

Other operating expenses

Occupancy and equipment expenses totaled $15.6 million for the third quarter of
2008, up $818 thousand or 6% over 2007. Growth in occupancy expense was due to 3
new branch locations added in the past year. Insurance expense increased $1.7
million compared to the third 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. The Company expects higher
deposit insurance expense as recently-announced increases in deposit insurance
premiums and other Treasury Department initiatives become effective.

Mortgage banking costs included a $1.4 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.

Subsequent to September 30, 2008, Visa and Mastercard announced that they had
reached an agreement in principal to settle antitrust litigation with Discover
Financial Services for approximately $2.8 billion. Management has estimated its
additional obligation for this settlement under Visa's retrospective
responsibility plan to be approximately $1.7 million. Management expects that
this accrual will be offset in future periods as Visa issues additional Class A
shares to provide funds for its litigation escrow account.

Income Taxes

Income tax expense was $23.0 million or 29% of book taxable income for the third
quarter of 2008 compared with $30.8 million or 34% of book taxable income for
the third quarter of 2007. The statute of limitations expired on an uncertain
tax position and the Company adjusted its current income tax liability to
amounts on filed tax returns for 2007 during the third quarter of 2008. Income
tax expense would have been $26.6 million or 33% of book taxable income for the
third quarter of 2008, excluding these items.

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 approximately $11.7
million at September 30, 2008.


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
10

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.

The increase in contribution to net income provided by the Oklahoma Corporate
Banking Division was due primarily to a $19.4 million increase in the fair value
of derivative contracts related to SemGroup. The decrease in contribution to net
income provided by the Regional Banking Division was due to increased net loans
charged off, primarily in the Arizona market.

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 contributed $34.1 million to net income for the third
quarter of 2008, up from $21.7 million for the third quarter of 2007. This
Division recognized a $53.0 million after-tax loss in the second quarter of 2008
on loans and derivative contracts with SemGroup. During the third quarter of
2008, the fair value of certain derivative contracts related to SemGroup
increased by $19.4 million due to falling energy prices. The change in fair
value of these contracts increased net income after taxes by $11.9 million for
the third quarter of 2008. The increase in fair value of derivative contracts is
included in Other Operating Revenue. Excluding changes in the fair value of
these contracts, the Oklahoma Corporate Banking Division's net income for the
third quarter of 2008 was $22.3 million, up $585 thousand over the third quarter
of 2007.

Net interest revenue increased $829 thousand or 2% compared to the third quarter
of 2007. Average earnings assets attributed to this division increased $151
million or 3% over the third quarter of 2007 to $4.7 billion. Average loans
increased $23 million or 1% to $4.4 billion. Average commercial loans decreased
$25 million or 1%. The decrease in average commercial loans was offset by a $38
million increase in average consumer loans, primarily indirect automobile loans,
and a $13 million increase in average real estate loans. Average funds provided
to the funds management unit by the Oklahoma Corporate Banking Division
increased $104 million due to deposit growth.

Operating revenue increased $3.3 million, excluding changes in the fair value of
SemGroup related derivative contracts. Operating revenue provided by TransFund
increased $1.1 million or 12% and service charges on commercial deposit accounts
were up $495 thousand or 9%. Fees received from standby letters of credit were
up $404 thousand or 20% over the third quarter of 2007. Operating expenses,
which consist primarily of personnel and data processing costs, increased $2.6
million or 9%.

BOSC's retail brokerage division. Consumer banking services are offered through
36 locations in Tulsa, 32 locations in Oklahoma City and 15 locations throughout
the state. Two locations are scheduled to open in the fourth quarter of 2008.

The Oklahoma Consumer Banking Division contributed net income of $7.1 million
for the third quarter of 2008, compared to net income of $9.3 million for the
third quarter of 2007. Net interest revenue decreased $2.8 million or 15% over
2007 due primarily to a decrease in the internal transfer pricing credit.

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 $2.4 million in the third quarter of 2008
compared to net income of $504 thousand in the third quarter of 2007. Changes in
the fair value of mortgage servicing rights, net of hedging activity, reduced
net income $2.7 million in 2008 and increased net income $127 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 $1.3 million in the third
quarter of 2008 and $500 thousand for the third quarter of 2007.

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 $468 million of residential mortgage loans
which generated net income of $513 thousand in the third quarter of 2008.

Loan Production Sector

Pre-tax losses from loan production totaled $1.0 million for the third quarter
of 2008 and $201 thousand for the third quarter of 2007. Loan production revenue
totaled $2.9 million in third quarter of 2008, including $5.1 million of
capitalized mortgage servicing rights, partially offset by net losses on
mortgage loans sold. Loan production revenue totaled $5.0 million in third
quarter of 2007. Capitalized mortgage servicing rights totaled $4.0 million. The
average initial fair value of servicing rights on mortgage loans funded was
1.47% for the third quarter of 2008 and 1.30% for the third quarter of 2007.
Mortgage loans funded totaled $347 million in third quarter of 2008 and $305
million in the third quarter of 2007. Approximately 55% and 20% of the loans
funded during the third quarter of 2008 were in Oklahoma and Texas,
respectively. The pipeline of mortgage loan applications totaled $507 million at
September 30, 2008, compared to $517 million at June 30, 2008 and $323 million
at September 30, 2007. Operating expenses, excluding direct loan production
costs which are recognized as part of the gain or loss on loans sold, totaled
$5.2 million in 2008 and $5.6 million in 2007.

Loan Servicing Sector

The loan servicing sector had a pre-tax loss of $3.4 million for the third
quarter of 2008 compared with pre-tax income of $467 thousand for the third
quarter of 2007. We recognized a net pre-tax loss of $4.4 million in the third
quarter of 2008 compared with a net pre-tax gain of $208 thousand in 2007 from
changes in the value of mortgage servicing rights and economic hedging
activities.

Servicing revenue, including revenue on loans serviced for affiliates, totaled
$5.0 million in third quarter of 2008 compared to $4.7 million in the same
period of 2007. The average outstanding balance of loans serviced, including
loans serviced for affiliates, was $5.8 billion during the third quarter of 2008
compared to $5.4 billion during 2007. Servicing revenue per outstanding loan
principal was 35 basis points in 2008 compared with 36 basis points in 2007.
Servicing costs totaled $2.2 million for the third quarter of 2008 and $1.9
million for the third quarter of 2007. At September 30, 2008, the total number
of loans serviced by BOk Mortgage totaled 57,970. Serviced loans delinquent 90
days or more or in process of foreclosure totaled 682 or 1.18% of the number of
loans serviced; 404 of these loans are in Oklahoma, 90 are in Arkansas, 59 are
in Kansas / Missouri and 35 are in Texas.

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.

At September 30, 2008, financial instruments with a fair value of $198 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 September 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 $ 4,498 $ (4,927)
Fair value of hedging instruments (4,649) 3,697
----------------- ----------------
Net $ (151) $ (1,230)
----------------- ----------------


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 $4.5 million while a
50 basis point decrease is expected to reduce the fair value $4.9 million. This
considers that there is an upper limit to appreciation in the value of servicing
rights as rates rise due to the contractual repayment terms of the loans and
other factors. There is much less of a limit 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
brokerage and trading activities. This line of business includes the activities
of BOSC, Inc., a registered broker / dealer and Cavanal Hill Investment
Management, Inc., an SEC-registered investment advisor.

Trust and private financial services includes sales of institutional, investment
and retirement products, loans and other services to affluent individuals,
businesses, not-for-profit organizations, and governmental agencies. Trust
services are provided primarily to clients throughout Oklahoma, Texas and New
Mexico. Additionally, trust services include a nationally competitive,
self-directed 401-(k) program and provides administrative and advisory services
to the American Performance family of mutual funds. Brokerage and trading
activities within the wealth management line of business consists of retail
sales of mutual funds, securities, and annuities, institutional sales of
securities and derivatives, bond underwriting and other financial advisory
services and customer risk management programs.

Wealth Management contributed net income of $9.4 million in the third quarter of
2008. This compared to net income of $6.2 million in the third quarter of 2007.
Growth in net income was due primarily to increased revenue from trading and
institutional securities sales. Net income for the third quarter of 2007 was
decreased $1.4 million for the after-tax cost of the settlement of certain
matters with the American Performance Funds. Net income for the Wealth
Management Division for the third quarter of 2008 increased $1.9 million or 25%
over the same period of 2007, excluding this settlement cost.

Trust fees and commissions for the Wealth Management line of business totaled
$17.5 million, up $501 thousand or 3% increase over last year. At September 30,
2008 and 2007, the Wealth Management line of business was responsible for trust
assets with aggregate market values of $30.4 billion and $31.8 billion,
respectively, under various fiduciary arrangements. The change in trust assets
reflected lower market value of assets managed partially offset by new business
generated during the year. We have sole or joint discretionary authority over
$11.5 billion of trust assets at September 30, 2008 compared to $11.8 billion of
trust assets at September 30, 2007. The fair value of non-managed assets was
$11.8 billion at September 30, 2008 and $12.2 billion at September 30, 2007.
Assets held in safekeeping totaled $7.1 billion at September 30, 2008.

Brokerage and trading activities provided $4.6 million of the Wealth Management
Division's net income in the third quarter of 2008 compared to $2.5 million in
2007. Trading fees and commissions revenue increased $5.8 million due primarily
to a $4.1 million increase in revenue from institutional securities and a $1.7
million increase in customer derivative revenue. Operating expenses, which

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 September 30, 2008, investment securities were carried at $244
million and had a fair value of $240 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 $6.4 billion at September 30,
2008, up $420 million compared with June 30, 2008. Mortgage-backed securities
represented 97% of total available for sale securities. The Company holds no
debt securities of corporate issuers.

</TABLE>

A primary risk of holding mortgage-backed securities comes from extension during
periods of rising interest rates or prepayment during periods of falling
interest rates. We evaluate this risk through extensive modeling of risk both
before making an investment and throughout the life of the security. The
expected duration of the mortgage-backed securities portfolio was approximately
2.8 years at September 30, 2008. Management estimates that the expected duration
would extend to approximately 3.3 years assuming an immediate 300 basis point
upward 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 FNMA and FHLMC. Principal and interest payments on the
underlying loans are fully guaranteed. At September 30, 2008, approximately $4.8
billion of the Company's mortgage-backed securities were issued by U.S.
government agencies.

The Company also holds $1.5 billion of mortgage-backed securities privately
issued by publicly-owned financial institutions. Credit risk on mortgage-backed
securities originated by these issuers is mitigated by investment in senior
tranches with additional collateral support. None of these securities are backed
by sub-prime mortgage loans, collateralized debt obligations or collateralized
loan obligations.

Approximately $439 million of the privately issued mortgage-backed securities
consisted of Alt-A mortgage loans. Approximately 83% of these securities are
credit enhanced with additional collateral support and approximately 87% of our
Alt-A mortgage-backed securities represents pools of fixed-rate mortgage loans.
None of the adjustable rate mortgages are payment option ARMs.

Our portfolio of available for sale securities also included preferred stocks
issued by seven financial institutions. These stocks were originally purchased
for $46 million and have a current carrying value of $32 million. Our carrying
value of these stocks has been reduced by $14 million of other-than-temporary
impairment charges recognized in previous periods. None of the institutions that
issued these stocks are in default and all of the issuers are rated investment
grade. BOK Financial does not own any equity securities issued by Fannie Mae or
Freddie Mac. These preferred stocks have certain debt-like features such as a
quarterly dividend based on LIBOR. However, the issuers of these stocks have no
obligation to redeem them. The aggregate fair value of these preferred stocks
decreased to $24 million at September 30, 2008 due to a significant widening of
spreads to LIBOR related to current market disruptions. Management believes that
the fair value of these securities will recover to our carrying value as spreads
to LIBOR return to a range of 400 basis points to 500 basis points over the next
two years.

Net unrealized losses on available for sale debt and equity securities totaled
$159 million at September 30, 2008 compared with net unrealized losses of $91
million at June 30, 2008. The aggregate gross amount of unrealized losses at
September 30, 2008 totaled $199 million. Management evaluated the securities
with unrealized losses to determine if we believed that the losses were
temporary. This evaluation considered factors such as causes of the unrealized
losses, support for debt securities provided by government guarantees or credit
enhancements, ratings of the respective issuers and other factors to assess the
prospects for recovery over various interest rate scenarios and time periods. 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
20

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.

Bank-Owned Life Insurance

The Company has approximately $234 million of bank-owned life insurance at
September 30, 2008. This investment is expected to provide a long-term source of
earnings to support existing employee benefit programs. Substantially all of the
funds are held in separate accounts and are invested in U.S. government,
mortgage-backed and corporate debt securities. The cash surrender value of
certain life insurance policies is further supported by a stable value wrap,
which protects against changes in the fair value of the investments. At
September 30, 2008, cash surrender value represented by the underlying fair
value of investments held in separate accounts was approximately $196 million
and cash surrender value represented by the value of the stable value wrap was
approximately $5.7 million. The stable value wrap was provided by a
highly-rated, domestic bank. The remaining cash surrender value primarily
represented the cash surrender value of policies held in the general accounts of
various insurance companies.

Loans

The aggregate loan portfolio before allowance for loan losses totaled $12.7
billion at September 30, 2008, a $162 million or 5% annualized increase since
June 30, 2008. Commercial loans and residential mortgage loans increased during
the third quarter of 2008. Commercial real estate loans and consumer loans
decreased during the same period.

Previously, the Company had reported residential loans held for sale by its
mortgage banking division as part of its loan portfolio. These loans are now
reported separately on the consolidated balance sheet and are excluded from this
discussion. Information for prior periods has been reclassified for consistent
presentation.

The commercial loan portfolio increased $235 million during the third quarter of
2008 to $7.3 billion at September 30, 2008 from the second quarter of 2008.
Energy loans totaled $2.1 billion or 17% of total loans. Outstanding energy
loans increased $205 million during the third quarter of 2008. Approximately
$1.8 billion of energy loans were to oil
21


and gas producers, up from $1.6 billion at June 30, 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
$1.1 billion in Oklahoma, $615 million in Texas and $392 million in Colorado.

The services sector of the loan portfolio totaled $2.0 billion or 16% 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 $718 million of the outstanding balance of
services loans is attributed to Texas, $644 million to Oklahoma, $244 million to
New Mexico, $141 million to Arizona and $108 million to Colorado.

Other notable loan concentrations by primary industry of the borrowers are
presented in Table 18.

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 September 30, 2008, the
outstanding principal balance of these loans totaled $2.1 billion. Substantially
all of these loans are to borrowers with local market relationships. BOK
Financial serves as the agent lender in approximately 23% 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 $2.7 billion or 21% of the loan portfolio
at September 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 $114 million from
the previous quarter end. Construction and land development loans decreased $53
million to $969 million. Loans secured by industrial facilities decreased $29
million and other commercial real estate loans decreased $95 million. Loans
secured by office buildings increased $48 million and loans secured by
multifamily residential properties increased $17 million.

Loans secured by land, residential lots and construction totaled $969 billion at
September 30, 2008. Approximately $252 million of these loans are attributed to
the Oklahoma market, $267 million to the Texas market, $178 million to the
Colorado market and $160 million to the Arizona market. The geographic
distribution of all other commercial real estate loans included $575 million in
Oklahoma, $586 million in Texas, $200 million in New Mexico, $166 million in
Arizona and $89 million in Colorado.

Residential mortgage loans totaled $1.7 billion, up $62 million since June 30,
2008. Permanent 1-4 family mortgage loans increased $63 million and home equity
loans decreased $1 million. We have no concentration in sub-prime residential
mortgage loans and our mortgage loan portfolio does not include payment option
adjustable rate mortgage loans or loans with initial rates that are below
market. Our portfolio of permanent 1- 4 family mortgage loans includes $130
million of community development loans. These loans are generally underwritten
to prime standards and require full documentation. Approximately $1.1 billion of
our residential mortgage loan portfolio is attributed to borrowers in Oklahoma
and $308 million to borrowers in Texas.

At September 30, 2008, consumer loans included $721 million of indirect
automobile loans. Approximately $454 million of these loans were purchased from
dealers in Oklahoma and $176 million were purchased from dealers in Arkansas.
The remaining $91 million were purchased from dealers in Texas. Indirect
automobile loans decreased $14 million since June 30, 2008. Approximately 6% of
the outstanding balance at September 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.

</TABLE>


Loan Commitments

BOK Financial enters into certain off-balance sheet arrangements in the normal
course of business. These arrangements included loan commitments which totaled
$5.3 billion and standby letters of credit which totaled $601 million at
September 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
23

represent future cash requirements. Approximately $311 thousand of the
outstanding standby letters of credit were issued on behalf of customers whose
loans are non-performing at September 30, 2008.

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. 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 September 30, 2008, the principal balance of loans sold subject to recourse
obligations totaled $388 million. Substantially all of these loans are to
borrowers in our primary markets including $274 million to borrowers in
Oklahoma, $44 million to borrowers in Arkansas, $22 million to borrowers in New
Mexico, $18 million to borrowers in the Kansas City area and $16 million to
borrowers in Texas. The separate reserve for these off-balance sheet commitments
was $8.6 million at September 30, 2008. Approximately 2.17% of the loans sold
with recourse with an outstanding principal balance of $8.2 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 $2.2 million for the third quarter of 2008. Net losses charged
against the reserve totaled $1.2 million for the third 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.

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 may be reduced and additional margin collateral may be
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.

Derivative contracts are carried at fair value. At September 30, 2008, the net
fair values of derivative contracts reported as assets under these programs
totaled $572 million, down from $1.4 billion at June 30, 2008 due to cash
settlements and falling energy prices. At September 30, derivative contracts
carried as assets included energy contracts with fair values of $415 million,
interest rate contracts with fair values of $93 million, agricultural product
contracts with fair values of $4 million and foreign exchange contracts with
fair values of $53 million. The aggregate net fair values of derivative
contracts held under these programs reported as liabilities totaled $374
million. 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 total amount of derivative liabilities at September 30, 2008 was
reduced by $217 million of cash collateral. A table showing the fair value of
derivative assets and liabilities, net of cash margin, is presented in Footnote
3 to the Consolidated Financial Statements (Unaudited), which follows this
report.
24

The fair value of derivative contracts reported as assets under these programs,
net of cash margin held by the Company, by category of debtor at September 30,
2008 was (in thousands):

Customers $362,308
Banks 73,619
Energy companies 82,802
Exchanges 51,196
Other 1,583
-------
Fair value of customer hedge asset derivative contracts, net $571,508
=======

In addition to cash margin, the Company accepts liens against physical
commodities as collateral for derivative contracts. The fair value of contracts
backed by energy production totaled approximately $221 million. Approximately
$67 million of the fair value of derivative contracts are with customers which
store or transport energy products. 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 largest amount due from a single counterparty, a subsidiary of an
international energy company, at September 30, 2008 was $67 million. The amount
due from this counterparty decreased to $35 million through receipt of cash
margin the next day.

Summary of Loan Loss Experience

BOK Financial maintains separate reserves for loan losses and reserves for
off-balance sheet credit risk. The combined allowance for loan losses and
reserve for off-balance sheet credit losses totaled $209 million or 1.65% of
outstanding loans and 99% of non-accruing loans at September 30, 2008. The
allowance for loan losses was $187 million and the reserve for off-balance
sheet credit losses was $22 million. At June 30, 2008, the combined allowance
for loan losses and off-balance sheet credit losses was $177 million or 1.41% of
outstanding loans and 119% of non-accruing loans.

Net loans charged off during the third quarter of 2008 totaled $20.2 million
compared to $39.0 million in the previous quarter and $4.9 million in the third
quarter of 2007. The ratio of net loans charged off to average outstanding loans
was 0.64% for the third quarter of 2008 compared with 1.26% for the second
quarter of 2008 and 0.17% for the third quarter of 2007.

Gross loans charged off in the third quarter of 2008 increased to $33.9 million
from $15.2 million in the second quarter of 2008, excluding a $26.0 million
SemGroup loan charge-off. Gross loans charged off included $11.4 million of
commercial loans, $14.4 million of commercial real estate loans and $5.3 million
of consumer loans. Recoveries of loans previously charged off increased to $13.7
million in the third quarter of 2008 from $2.5 million in the previous quarter.
We recovered $7.1 million from a loan charged off in 2005 and $4.0 million from
a loan charged off in 2001 during the third quarter of 2008.

Consumer loan net charge-offs, which includes indirect auto loan and deposit
account overdraft losses, totaled $3.7 million for the third quarter of 2008, up
$774 thousand over the previous quarter. Net charge-offs of indirect auto loans
totaled $2.3 million for the third quarter of 2008 and $1.7 million for the
second quarter of 2008. Net indirect auto loans charged off were $1.4 million in
the Oklahoma market, $668 thousand in the Arkansas market and $239 thousand in
the Texas market. Approximately 2.29% of the indirect automobile loan portfolio
is past due 30 days or more, including 2.23% in Oklahoma, 2.56% in Arkansas and
2.08% in Texas. At June 30, 2008, approximately 1.95% of the indirect automobile
loan portfolio was past due 30 days or more. This compares to a national average
of 2.60% for indirect automobile loans past due 30 days or more at June 30,
2008.

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 20
presents the trend of reserves for off-balance sheet credit losses and the
relationship between the reserve and loan commitments. The relationship between
the combined reserve for credit losses and outstanding loans is also presented
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 September 30, 2008, specific
impairment reserves totaled $4.0 million on total impaired loans of $201
million. Specific impairment reserves were $11.0 million on total impaired loans
of $139 million at June 30, 2008. Approximately $7.5 million of loans impaired
at June 30, 2008 were charged off in the third quarter.

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, commercial real estate, residential mortgage and consumer loan
portfolios. Nonspecific reserves attributed to general economic conditions
increased in the third quarter of 2008. Weakness in the economy became more
apparent due to disruption in the credit markets, lower consumer confidence and
continued weakness in residential real estate markets.

The provision for credit losses totaled $52.7 million for the third quarter of
2008, $59.3 million for the second quarter of 2008 and $7.2 million for the
third 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. Factors considered in determining the provision for credit losses for
the third quarter of 2008 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 potential problem loans increased.
26

Nonperforming Assets

Non-performing assets totaled $252 million or 1.98% of outstanding loans and
repossessed assets at September 30, 2008, up $71 million since June 30, 2008.
The increase in non-performing assets included an expected $36 million from
amounts due from SemGroup on funded letters of credit and derivative contracts
that terminated during the third quarter. Non-performing assets included $9.6
million of restructured residential mortgage loans guaranteed by agencies of the
U.S. government and $16 million of loans and repossessed assets acquired with
First United Bank in the second quarter of 2007. The Company will be reimbursed
by the sellers up to $8 million for any losses incurred during a three-year

Our 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
28

borrowers' ability to comply with current repayment terms. These potential
problem loans totaled $81 million at September 30, 2008 and $40 million at June
30, 2008. The current composition of potential problem loans by primary industry
included real estate - $66 million, healthcare - $11 million and services - $4
million. Potential problem real estate loans consisted primarily of loans to
residential builders in the Colorado market of $20 million, the Arizona market
of $16 million and the Texas market of $16 million.


Deposits

Deposit accounts represent our largest funding source. Average deposits
represented approximately 65% of total liabilities and capital for the third
quarter of 2008, compared with 62% for the second quarter of 2008 and 67% for
the third quarter of 2007. The increase in average deposits relative to other
funding sources in the third quarter was due largely to an increase in brokered
deposits as the Company changed its mix of funding sources to increase
short-term liquidity. Average brokered deposits were $1.0 billion for the third
quarter of 2008 and $482 million for the second quarter of 2008.

During the third quarter of 2008, the Company revised the presentation of
certain deposit accounts. Previously, demand deposit accounts were shown net of
adjustments made to manage its reserve requirements. These adjustments were
excluded from the current presentation to provide a more-meaningful presentation
of the Company's deposit accounts. All prior periods have been reclassified for
a consistent presentation. The reclassification had no effect on total deposits,
interest expense, net interest revenue or net interest margin.

Average deposits totaled $14.3 billion for the third quarter of 2008, a $967
million increase over the second quarter of 2008. Average deposits increased
$1.3 billion compared with the third quarter of 2007.

Average time deposits increased $716 million over the second quarter of 2008,
including a $453 million increase in average brokered deposits. Average time
deposits increased $263 million excluding brokered deposits. Time deposits
generated through our Wealth Management Division and Oklahoma Corporate Banking
Division increased $136 million and $48 million, respectively. Average consumer
time deposits increased $18 million in New Mexico and $17 million in Texas.

Average interest-bearing transaction deposit accounts continued to grow in the
third quarter of 2008, up $145 million over the second quarter of 2008. Average
demand deposits increased $105 million over the second quarter of 2008 due
primarily to our commercial energy customers.

Core deposits, which we define as deposits of less than $100,000, excluding
public funds and brokered deposits, averaged $6.5 billion for the third quarter
of 2008, $6.5 billion for the second quarter of 2008 and $6.6 billion for the
third quarter of 2007. Accounts with balances in excess of $100,000 excluding
brokered deposit accounts averaged $5.9 billion for the third quarter of 2008,
$5.5 billion for the second quarter of 2008 and $5.1 billion for the third
quarter of 2007.

The distribution of deposit accounts among our principal markets is shown in
Table 22.

Borrowings and Capital

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 lack
of restrictive covenants in this agreement also provides the Company time to
maximize the recovery on nonperforming assets. At September 30, 2008, the
outstanding balance under this credit agreement was $50 million.

Subsequent to September 30, the U.S. Treasury announced its TARP Capital
Purchase Program. The TARP program allows participating banks to increase
capital by issuing preferred stock and common stock warrants to the U.S.
government. The Company has been encouraged to apply and will make a decision
about participating in the TARP program before the November 14, 2008 deadline.

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 $128 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 $109
million under this policy.

Equity capital for BOK Financial was $1.9 billion at September 30, 2008, down
$1.9 million from June 30, 2008. Net income less cash dividend paid increased
equity $41.5 million. Accumulated other comprehensive losses increased $41.9
million during the third quarter of 2008 due primarily to an increase in net
unrealized losses on available for sale securities. Employee stock option
transactions increased equity capital $1.8 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, 784,073 shares have
been repurchased by the Company for $38.7 million. The Company repurchased
75,000 shares for $3.3 million in the third quarter of 2008.

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. The capital ratios for BOK Financial on a consolidated basis are
presented in Table 23.

In addition to deposits, subsidiary bank liquidity is provided primarily by
federal funds purchased, securities repurchase agreements and Federal Home Loan
Bank borrowings. Federal funds purchased consist primarily of unsecured,
overnight funds acquired from other financial institutions. Securities
repurchase agreements generally mature within 90 days and are secured by certain
available for sale securities. Federal Home Loan Bank borrowings are generally
short term and are secured by a blanket pledge of eligible collateral (generally
unencumbered U.S. Treasury and mortgage-backed securities, 1-4 family mortgage
loans and multifamily mortgage loans). At September 30, 2008, the outstanding
balance of federal funds purchased totaled $1.7 billion, securities repurchase
agreements totaled $2.0 billion and Federal Home Loan Bank borrowings totaled
$991 million.

Subsequent to September 30, 2008, the U.S. Treasury announced its Treasury
Liquidity Guarantee Program ("TGLP"). TGLP is intended to improve market
liquidity by providing FDIC insurance to certain non-interest bearing
transaction deposit accounts, interbank funding and newly issued unsecured debt.
The cost of the TGLP ranges from an additional 10 basis points for certain
non-interest bearing transaction accounts to an additional 75 basis points on
interbank funding
31

(federal funds purchased) and newly issued unsecured debt.

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.
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.
32

The Company's primary interest rate exposures included the Federal Funds rate,
which affects short-term borrowings, and the prime lending rate and LIBOR, which
are the basis for much of the variable-rate loan pricing. Additionally, mortgage
rates directly affect the prepayment speeds for mortgage-backed securities and
mortgage servicing rights. Derivative financial instruments and other financial
instruments used for purposes other than trading are included in this
simulation. The model incorporates assumptions regarding the effects of changes
in interest rates and account balances on indeterminable maturity deposits based
on a combination of historical analysis and expected behavior. The impact of
planned growth and new business activities is factored into the simulation
model. The effects of changes in interest rates on the value of mortgage
servicing rights are excluded from Table 24 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 $3.6 million. At September 30, 2008, the VAR was $1.8 million.
The greatest value at risk during the third quarter of 2008 was $2.1 million.
The value at risk guideline was exceeded with appropriate approvals by
management to take advantage of wide yields available on certain securities
during the quarter.

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.

Previously, the Company had reported residential loans held for sale by its
mortgage banking division as part of its loan portfolio. These loans are now
reported separately on the consolidated balance sheet.

The Company revised the presentation of certain deposit accounts. Previously,
demand deposit accounts were shown net of adjustments made to manage its reserve
requirements. These adjustments were excluded from the current presentation to
provide a more meaningful presentation of the Company's deposit accounts. This
reclassification had no effect on total deposits, interest expense, net interest
revenue or net interest margin.

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 September 30, 2008 was reduced by $19 million and $217 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
39

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 September 30, 2008 are as follows (in thousands):


<TABLE>

Liabilities:
Certificates of deposit 528,715 528,715
Derivative contracts 377,973 377,973

</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.

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.

At June 30, 2008, the fair value of derivative contracts with SemGroup LP of
$36.6 million was largely based 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 the derivative contracts with SemGroup
using information currently available, including information provided by a
nationally recognized financial advisor to SemGroup. During the third quarter of
2008, the fair value of these contracts decreased by $4.6 million. The decrease
in fair value, which was based largely on significant unobservable inputs and
changes in energy prices during the quarter, was recognized as a reduction of
fees and commissions revenue. All derivative contracts with SemGroup either
expired or were terminated during the third quarter. The fair value of amounts
due from SemGroup under these contracts totaled $32.0 million. This amount is
included in outstanding commercial loans at September 30, 2008.

No significant fair value measurements of significant assets or liabilities
measured on a non-recurring basis were made during the first three quarters 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 September 30, 2008, the fair value and
contractual principal amount of these certificates was $529 million and $537
million, respectively. Change in the fair value of these certificates of deposit
resulted in an unrealized gain during the third quarter and first three quarters
of 2008 of $7.1 million and $7.7 million, respectively, which is included in
Gain (Loss) on Derivatives, net on the Consolidated Statement of Earnings.

(10) Commitments and 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
45

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 at which time the SEC Staff advised that the
Staff had not determined whether to recommend any action to the Commission. On
September 25, 2008, The SEC Staff requested, and BOK and AXIA agreed to, a
tolling agreement for any action the SEC might take until January 15, 2009.
Nothing further has occurred as of the time of this filing.

As a member of Visa, BOK Financial is obligated for a proportionate share of
certain covered litigation losses incurred by Visa under a retrospective
responsibility plan. A contingent liability was recognized for the Company's
share of Visa's covered litigation liabilities. Visa funded an escrow account to
cover litigation claims, including covered litigation losses under the
retrospective responsibility plan, with proceeds from its initial public
offering in the first quarter of 2008. BOK Financial recognized a receivable for
its proportionate share of this escrow account which equals the contingent
liability previously recognized.

Subsequent to the third quarter of 2008, Visa announced an agreement to settle
covered litigation with Discover Financial Services for approximately $1.8
billion. BOK Financial recognized an additional contingent liability of $1.7
million for its proportionate share of this settlement in the third quarter of
2008. This additional liability is expected to be offset in future periods as
additional funds are provided to the escrow account.

BOK Financial received 410,562 Visa Class B shares as part of Visa's initial
public offering in the first quarter of 2008. 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 shares 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.

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 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.
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.

(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 September 30, 2008, outstanding commitments and letters of credit were as
follows (in thousands):

September 30,
2008
--------------
Commitments to extend credit $ 5,340,615
