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

Performance Summary

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

Highlights of the quarter included:

o    Acquisitions  of Worth  National Bank and First United Bank were  completed
     during the quarter.  Worth added net loans of $281 million,  total deposits
     of $369 million and five  banking  locations  in Fort Worth,  Texas.  First
     United added net loans of $94 million,  total  deposits of $133 million and
     eleven bank locations in the Denver,  Colorado area. These acquisitions did
     not significantly  affect average asset,  average liabilities or net income
     for the second quarter.

o    Net interest  revenue grew $13.8 million or 11% over the second  quarter of
     2006 and $6.1  million or 16%  annualized  over the first  quarter of 2007,
     excluding the impact of acquisitions.

o    Average  earning  assets  increased  $2.2  billion  or 15% over the  second
     quarter of 2006. Average  outstanding loans totaled $11.3 billion,  up $1.9
     billion or 20%. Average deposits totaled $12.4 billion,  up $1.2 billion or
     10% over the second quarter of 2006.

o    Net interest margin was 3.31% for the second quarter of 2007, 3.32% for the
     first quarter of 2007 and 3.40% for the second  quarter of 2006.  The yield
     on average  earning assets was 7.00%,  up from 6.71% for the second quarter
     of 2006 and down two basis points from the preceding  quarter.  The cost of
     interest-bearing  funds was 4.12% for the second  quarter of 2007  compared
     with 3.73% for the second  quarter of 2006 and 4.14% for the first  quarter
     of 2007.

o    Provision  for credit  losses was $7.8  million  for the second  quarter of
     2007, up from $3.8 million for the second  quarter of 2006 and $6.5 million
     for the first quarter of 2007. Non-performing assets totaled $60 million or
     0.52% of  outstanding  loans at June 30,  2007 and $39  million or 0.40% of
     outstanding  loans at June

 3

     30,  2006.   Non-performing  assets  totaled  $50.7  million  or  0.44%  of
     outstanding loans at June 30, 2007, excluding acquisitions.

o    The combined  allowance for loan losses and reserve for  off-balance  sheet
     credit losses  totaled $139 million or 1.20% of  outstanding  loans at June
     30, 2007,  $126 million or 1.30% at June 30, 2006 and $134 million or 1.21%
     of outstanding loans at March 31, 2007.

o    Fees and commissions  revenue  increased $4.9 million or 5% over the second
     quarter of 2006.  Transaction  card revenue grew $3.0 million or 15% due to
     volume increases,  and trust fees grew $1.7 million or 10% due primarily to
     increases in the fair value of trust assets.  Revenue from  bank-owned life
     insurance totaled $2.5 million for the second quarter of 2007 compared with
     $32 thousand in 2006 due to a $202 million  investment in  bank-owned  life
     insurance at the end of the third quarter of 2006. Other revenue  decreased
     $2.9 million due primarily to fees earned on margin asset balances.

o    Operating  expenses,  excluding  changes  in the  fair  value  of  mortgage
     servicing  rights increased $15.3 million or 12%;  personnel  expenses grew
     $9.5 million or 13% over the second quarter of 2006.

o    The fair value of mortgage  servicing  rights increased $5.1 million during
     the second  quarter of 2007. At the same time, the fair value of securities
     held as an  economic  hedge of mortgage  servicing  rights  decreased  $5.7
     million for a net pre-tax loss of $621 thousand.  During the second quarter
     of 2006, the fair value of mortgage servicing rights increased $3.6 million
     and the fair value of securities  designated as an economic hedge decreased
     $2.5 million for a net pre-tax gain of $1.1 million.

o    Debt rating was placed on positive outlook by Standard & Poors.


Results of Operations

Net Interest Revenue

Tax-equivalent  net  interest  revenue  increased to $137 million for the second
quarter of 2007 from $123 million for the same period of 2006,  due primarily to
a $1.9 billion or 20% increase in average  outstanding  loan principal.  Average
loan growth was funded by a $1.2 billion or 10% increase in average deposits and
a $809  million  increase  in borrowed  funds.  Table 1 shows the effects on net
interest  revenue  of changes in average  balances  and  interest  rates for the
various types of earning assets and interest-bearing liabilities.

Net interest margin, the ratio of tax-equivalent net interest revenue to average
earning assets was 3.31% for the second quarter of 2007, compared with 3.40% for
the second quarter of 2006 and 3.32% for the first quarter of 2007. The yield on
average  earning assets was 7.00%,  up 29 basis points  compared with the second
quarter of 2006 and down 2 basis points over the preceding quarter. Beginning in
2005,  the  weighted  average  spread  of rates  earned on our  commercial  loan
portfolio  over LIBOR funding  sources  decreased from  approximately  272 basis
points to  approximately  239 basis  points due largely to  competitive  pricing
pressure.  Over the same period,  deposit  account  balances  have been steadily
migrating to higher costing products.  Non-interest bearing funds and changes in
the mix of funding  sources added 43 basis points to the net interest  margin in
second  quarter of 2007 compared with 42 basis points for the second  quarter of
2006 and 44 basis points for the preceding quarter.

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

Our overall  objective is to manage the Company's balance sheet to be relatively
neutral to changes in interest rate.  Approximately  69% of our commercial  loan
portfolio is either  variable  rate or fixed rate that will  reprice  within one
year.  These  loans are funded  primarily  by deposit  accounts  that are either
non-interest  bearing, or that reprice more slowly than the loans. The result is
a balance sheet that would be asset sensitive, which means that assets generally

 4

reprice more  quickly  than  liabilities.  Among the  strategies  that we use to
achieve  a   relatively   rate-neutral   position,   we   purchase   fixed-rate,
mortgage-backed  securities to offset the  short-term  nature of the majority of
the Company's funding sources. The  liability-sensitive  nature of this strategy
provides an offset to the asset-sensitive characteristics of our loan portfolio.

We also use derivative  instruments  to manage our interest rate risk.  Interest
rate swaps with a combined  notional  amount of $632 million  convert fixed rate
liabilities to floating rate based on LIBOR.  The purpose of these  derivatives,
which  include  interest  rate  swaps  designated  as fair value  hedges,  is to
position  our  balance  sheet to be  relatively  neutral to changes in  interest
rates.  We also have interest rate swaps with a notional  amount of $100 million
that convert  prime-based loans to fixed rate. The purpose of these derivatives,
which have been designated as cash flow hedges,  also is to position our balance
sheet to be relatively neutral to changes in interest rates.

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

(1) Changes attributable to both volume and yield/rate are allocated to both

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

Other Operating Revenue

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

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

 5

We believe that a variety of fee revenue sources provide an offset to changes in
interest  rates,  values in the equity  markets,  commodity  prices and consumer
spending, all of which can be volatile.

Fees and commissions revenue

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

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

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

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

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

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

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

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

Securities and derivatives

BOK Financial recognized net losses of $6.3 million on securities for the second
quarter of 2007,  including net losses of $5.7 million on securities  held as an
economic  hedge of mortgage  servicing  rights.  Securities  held as an economic
hedge of the mortgage  servicing  rights which are separately  identified on the
balance  sheet as  "mortgage  trading  securities"  are  carried at fair  value.
Changes in fair value are  recognized  in earnings as they occur.  The Company's
use  of  securities  as an  economic  hedge  of  mortgage  servicing  rights  is
more-fully  discussed in the Line of Business - Mortgage Banking section of this
report.  During the second quarter of 2006, BOK Financial  recognized net losses
of $2.5 million on securities  held as an economic  hedge of mortgage  servicing
rights and net losses of $1.3 million on other securities.

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

 6

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

quarter  of 2007 and $3.6  million  in the  second  quarter  of 2006.  Excluding
changes in the value of mortgage servicing rights,  operating expenses increased
$15.3  million or 12% over the second  quarter of 2006 due  primarily  to higher
personnel expense.

---------------------------------------------------------------------------------------------------------------------


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

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

 7

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

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

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

Data processing and communications expense

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

Professional fees and services

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

Income Taxes

Income  tax  expense  was $29.3  million or 35% of book  taxable  income for the

Lines of Business

BOK Financial  operates five  principal  lines of business:  Oklahoma  corporate
banking,  Oklahoma consumer banking,  mortgage banking,  wealth management,  and
regional  banking.  Mortgage  banking  activities  include loan  origination and
servicing across all markets served by the Company.  Wealth management  provides
brokerage  and  trading,  private  financial  services and  investment  advisory
services in all  markets.  It also  provides  fiduciary  services in all markets
except  Colorado.  Fiduciary  services  in  Colorado  are  included  in regional
banking.  Regional  banking consist  primarily of corporate and consumer banking
activities in the respective local markets. Worth National Bank and First United
Bank are included in regional  banking results for the second quarter of 2007 in
Texas and Colorado, respectively.

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

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

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

Economic capital is assigned to the business units by a capital allocation model
that reflects management's  assessment of risk. This model assigns capital based
upon credit,  operating,  interest rate and market risk inherent in our business
lines and recognizes the diversification  benefits among the units. The level of
assigned  economic  capital is a combination  of the risk taken by each business
line, based on its actual exposures and calibrated to its own loss history where
possible.  Additional  capital  is  assigned  to the  regional  banking  line of
business based on our investment in those entities.

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

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

thousand or 9%.

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

Mortgage Banking

BOK Financial  engages in mortgage banking  activities  through the BOk Mortgage
Division  of  Bank  of  Oklahoma.  These  activities  include  the  origination,
marketing and servicing of conventional and government-sponsored mortgage loans.
Mortgage banking  activities  provided net income of $122 thousand in the second
quarter of 2007,  compared with $1.3 million in the second  quarter of 2006. The
change in fair value of  mortgage  servicing  rights,  net of  economic  hedging
decreased net income $379  thousand in the second  quarter of 2007 and increased
net income $660 thousand in the second quarter of 2006.

Mortgage banking  activities  consisted of two primary sectors,  loan production
and loan servicing.  The loan  production  sector  generally  performs best when
mortgage  rates  are  relatively  low and loan  origination  volumes  are  high.
Conversely,  the loan  servicing  sector  generally  performs best when mortgage
rates are relatively  high and prepayments are low.  Mortgage  commitment  rates
increased 39 basis points  during the second  quarter of 2007 ending the quarter
at 6.45%. During the second quarter of 2006, mortgage commitment rates increased
36 basis points to 6.61% at June 30, 2006.

Loan Production Sector

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

 11

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

Loan Servicing Sector

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

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

BOK Financial  designates a portion of its  securities  portfolio as an economic
hedge against the risk of loss on its mortgage servicing rights. Mortgage-backed
securities  and U.S.  government  agency  debentures are designated as "mortgage
trading  securities" when prepayment risks exceed certain levels.  Additionally,
interest rate  derivative  contracts may also be designated as an economic hedge
of the risk of loss on  mortgage  servicing  rights.  Because the fair values of
these  instruments  are  expected  to vary  inversely  to the fair  value of the
servicing  rights,  they are expected to partially  offset risk. These financial
instruments  are carried at fair value.  Changes in fair value are recognized in
current period income.  No special hedge  accounting  treatment is applicable to
either the mortgage servicing rights or the financial instruments  designated as
an economic hedge.

This hedging strategy presents certain risks. A well-developed market determines
the  fair  value  for  the  securities  and  derivatives,  however  there  is no
comparable market for mortgage servicing rights.  Therefore, the computed change
in value of the servicing  rights for a specified  change in interest  rates may
not correlate to the change in value of the securities.

At June 30, 2007, financial  instruments with a fair value of $139 million and a
net  unrealized  loss of $5.3 million were held for the economic  hedge program.
The interest rate  sensitivity of the mortgage  servicing  rights and securities
held as a hedge is  modeled  over a range of +/- 50  basis  points.  At June 30,
2007, the pre-tax results of this modeling on

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

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

primarily from operations in Texas. Net income from Texas  operations  increased
$1.5 million or 12%  compared  with the same period of 2006.  In  addition,  net
income  for 2007 in  Colorado  and  Arizona  increased  $716  thousand  and $107

revenue grew $2.6 million or 7%. Average  earning assets  increased $347 million
or 10% from the  second  quarter of 2006.  This  increase  resulted  from a $506
million  increased  in average  outstanding  loan  balances  and an $111 million
increase  in  securities.  The  growth in  average  earning  assets  was  funded
primarily by a $278 million increase in average deposits and a decrease in funds
sold to the funds management unit.  Operating expenses increased $3.1 million or
15%. Personnel costs were up $2.1 million or 18% over the same period last year.

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

$642 thousand or 20% increase in personnel costs.

Net income from New Mexico  operations  decreased $246 thousand or 5%. Net loans
charged off  increased  to $1.4 million in the second  quarter of 2007  compared
with net  charge-offs  of $692  thousand  in the  second  quarter  of 2006.  Net
interest revenue totaled $13.2 million,  up $1.3 million or 11%. Average earning
assets grew $181 million or 13%,  including a $134  million  increase in average
outstanding  loans.  Average  deposits in the New Mexico  market  increased  $67
million. Operating expenses increased $1.2 million or 18%.

We continue to expand  operations in the Arizona market since the acquisition of
Bank of Arizona in the second quarter of 2005. Net interest  revenue was up $1.3
million or 35% over the second quarter of 2006.  Outstanding loans attributed to
the Arizona market averaged $502 million for the second quarter of 2007, up $232
million  from the second  quarter of 2006's  average of $270  million.  Deposits
averaged $115 million for the second  quarter of 2007,  down $6 million from the
second  quarter of 2006.  Loan  growth was funded by  borrowings  from the funds
management unit.  Operating  expenses  increased $1.1 million or 35%.  Personnel
costs were up $532  thousand and  occupancy  and  equipment  expense was up $126
thousand as we continue to build a  commercial  banking  presence in Phoenix and

Financial Condition

Securities

Securities are classified as either held for  investment,  available for sale or
trading   based   upon   asset/liability   management   strategies,   liquidity,
profitability  objectives and regulatory  requirements.  Investment  securities,
which consist  primarily of Oklahoma  municipal  bonds,  are carried at cost and
adjusted for amortization of premiums or accretion of discounts.  Management has
the ability and intent to hold these securities until they mature. Available for
sale securities, which may be sold prior to maturity, are carried at fair value.
Unrealized  gains or losses,  less deferred  taxes,  are recorded as accumulated
other  comprehensive  income in shareholders'  equity.  Certain  mortgage-backed
securities,  identified as mortgage trading securities,  have been designated as
economic hedges of mortgage  servicing  rights.  These securities are carried at
fair value with changes in fair value recognized in current period income. These
securities  are held with the intent that gains or losses will offset changes in
the fair value of  mortgage  servicing  rights.  The  Company  also  maintains a
separate trading securities portfolio.  Trading portfolio securities,  which are
also  carried  at fair value with  changes in fair value  recognized  in current
period income, are acquired and held with the intent to sell at a profit.

The amortized cost of available for sale securities totaled $5.1 billion at June
30,  2007 and  $4.8  billion  at  March  31,  2007.  Mortgage-backed  securities
continued to represent  substantially  all  available  for sale  securities.  As
previously discussed in the Net Interest Revenue section of this report, we hold
mortgage backed  securities as part of our overall interest rate risk management
strategy.

The primary  risk of holding  mortgage-backed  securities  comes from  extension
during periods of rising interest rates or prepayment  during periods of falling
interest  rates. We evaluate this risk through  extensive  modeling of risk both
before  making  an  investment  and  throughout  the life of the  security.  The
effective duration of the mortgage-backed securities portfolio was approximately
2.8 years at June 30, 2007 and 2.5 years at March 31, 2007. Management estimates
that the effective duration of the  mortgage-backed  securities  portfolio would
extend to 3.4 years assuming a 300 basis point immediate rate shock.

The gross amount of unrealized  losses on available for sale securities  totaled
$140  million at June 30,  2007  compared  with gross  unrealized  losses of $83
million at March 31, 2007. The increase in unrealized  losses during the quarter
was due primarily to rising interest rates and an increase in the spread between
market  rates  on  mortgage-backed  securities  and  benchmark  interest  rates.
Management  evaluated the securities with  unrealized  losses to determine if we
believe that the losses were temporary.  This evaluation considered factors such
as causes of the  unrealized  losses and  prospects  for  recovery  over various
interest  rate  scenarios  and time  periods.  The  portfolio  does not hold any
securities backed by sub-prime mortgage loans,  collateralized  debt obligations
or collateralized loan obligations. Approximately $400

 17

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

Bank-Owned Life Insurance

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

Loans

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

The  commercial  loan  portfolio  totaled $6.5 billion at June 30, 2007.  Energy
loans  totaled  $1.8  billion or 16% of total  loans.  Outstanding  energy loans
increased $62 million,  or 14%  annualized,  during the second  quarter of 2007.
Approximately  $1.6 billion of loans in the energy  portfolio was to oil and gas
producers.  The amount of credit available to these customers  generally depends
on a  percentage  of  the  value  of  their  proven  energy  reserves  based  on
anticipated  prices.  The  energy  category  also  included  loans to  borrowers
involved in the  transportation  and sale of oil and gas and to  borrowers  that
manufacture  equipment or provide  other  services to the energy  industry.  The
services sector of the portfolio  totaled $1.7 billion,  or 14% of the Company's
total  outstanding  loans.  Loans in this sector of the portfolio  increased $90
million since March 31, 2007. The services  sector consists of a large number of
loans  to  a  variety  of  businesses,  including  communications,   gaming  and
transportation  services.  Approximately  $1.1 billion of the services sector is
made up of loans with balances of less than $10 million.

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

BOK Financial participates in shared national credits when appropriate to obtain
or maintain business relationships with local customers. Shared national credits
are defined by banking  regulators  as credits of more than $20 million and with
three or more non-affiliated  banks as participants.  The outstanding  principal
balances of these loans  totaled  $1.5 billion at June 30, 2007 and $1.4 billion
at March 31, 2007. Substantially all of these loans were to borrowers with local
market relationships.  BOK Financial serves as the agent lender in approximately
24% of the shared  national  credits,  based on dollars  committed.  Our lending
policies  generally  avoid  loans in which  we do not  have the  opportunity  to
maintain or achieve other business relationships with the customer.

Commercial  real estate loans totaled $2.8 billion or 24% of the loan  portfolio
at June 30, 2007.  Construction and land development loans totaled $917 million,
down $9 million since March 31, 2007. Construction and land development included
$718 million of loans  secured by single family  residential  lots and premises,
unchanged  from the  previous  quarter's  end.  The  major  components  of other
commercial  real estate  loans were office  buildings - $434  million and retail
facilities - $396 million.

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

Loan Commitments

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

 20

depend on the borrower's financial condition, collateral value or other factors.
Standby  letters  of credit  are  unconditional  commitments  to  guarantee  the
performance  of our customer to a third party.  Since some of these  commitments
are expected to expire before being drawn upon, the total commitment  amounts do
not necessarily represent future cash requirements.


Derivatives with Credit Risk

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

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

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

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

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

A  deterioration  of the  credit  standing  of one or more of the  customers  or
counterparties to these contracts may result in BOK Financial recognizing a loss
as the fair value of the  affected  contracts  may no longer move in tandem with
the  offsetting  contracts.  This  could  occur if the  credit  standing  of the
customer  or  counterparty  deteriorated  such  that  either  the fair  value of
underlying  collateral no longer  supported  the contract or the  counterparty's
ability to provide margin collateral was impaired.

Derivative contracts are carried at fair value. At June 30, 2007, the fair value
of derivative  contracts  reported as assets under these  programs  totaled $265
million.  This  included  energy  contracts  with fair  values of $203  million,
interest  rate  contracts  with fair values of $45 million and foreign  exchange
contracts  with  fair  values  of $15  million.  The  aggregate  fair  values of
derivative contracts reported as liabilities totaled $277 million. Approximately
78% of the fair value of asset contracts was with customers.  The credit risk of
these contracts is generally backed by energy production.  The remaining 22% was
with dealer  counterparties.  The maximum net exposure to any single customer or
counterparty totaled $34 million.


Summary of Loan Loss Experience

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

 21

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

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

The Company considers credit risk from loan commitments and letters of credit in
its  evaluation  of the  adequacy  of the reserve  for loan  losses.  A separate
reserve for off-balance  sheet credit risk is maintained.  Table 18 presents the
trend of reserves  for  off-balance  sheet  credit  losses and the  relationship
between the reserve and loan commitments.  The relationship between the combined
reserve for credit losses and outstanding  loans is also presented to facilitate
comparison  with peer  banks and  others  who have not  adopted  this  preferred
presentation.  The provision for credit losses  included the combined  charge to
expense for both the  reserve  for loan  losses and the reserve for  off-balance
sheet credit losses. All losses incurred from lending activities will ultimately
be reflected in charge-offs  against the reserve for loan losses following funds
advanced against outstanding  commitments and after the exhaustion of collection
efforts.  The reserve for off-balance sheet credit losses would decrease and the
reserve for loan losses would increase as outstanding commitments are funded.

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

Nonspecific  reserves are  maintained  for risks beyond  factors  specific to an
individual  loan or those  identified  through  migration  analysis.  A range of
potential  losses is determined for each risk factor  identified.  The ranges of
potential losses for the more significant factors were:

Concentration in large loans   -    $1.4 million to $2.8 million       $1.4 million to $2.8 million


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

Nonperforming Assets

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

The loan review process also identifies  loans that possess more than the normal
amount of risk due to deterioration  in the financial  condition of the borrower
or the value of the  collateral.  Because the borrowers are still  performing in
accordance  with  the  original  terms of the  loan  agreements,  and no loss of
principal  or  interest  is  anticipated,  these  loans  were  not  included  in
Nonperforming Assets. Known information does, however, cause management concerns
as to the  borrowers'  ability to comply with  current  repayment  terms.  These
potential  problem loans totaled $45 million at June 30, 2007 and $27 million at
March 31, 2007.  Potential problem loans by primary industry included healthcare
- $23 million, services - $14 million and real estate - $6 million.

Deposits

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

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

 23

brokered  deposits and public funds,  increased $103 million to $1.1 billion for

Borrowings and Capital

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

This credit  agreement  includes  certain  restrictive  covenants that limit the
Company's  ability to borrow  additional  funds, to make  investments and to pay
cash dividends on common stock.  These  covenants also require BOK Financial and
subsidiary  banks to maintain  minimum  capital levels and to exceed minimum net
worth ratios.  BOK Financial  met all of the  restrictive  covenants at June 30,
2007.

The primary source of liquidity for BOK Financial is dividends  from  subsidiary
banks,  which are limited by various  banking  regulations  to net  profits,  as
defined,  for the  preceding  two years.  Dividends  are further  restricted  by
minimum capital  requirements.  After issuing dividends in the second quarter of
2007 to fund acquisitions,  the subsidiary banks could declare up to $35 million
of  dividends  based  on the most  restrictive  limitations  without  regulatory
approval.  Management  has  developed and the Board of Directors has approved an
internal  capital policy that is more  restrictive  than the regulatory  capital
standards.  The  subsidiary  banks could declare  dividends of up to $18 million
under this policy.

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

Capital is managed to  maximize  long-term  value to the  shareholders.  Factors
considered in managing  capital include  projections of future  earnings,  asset
growth  and   acquisition   strategies,   and   regulatory   and  debt  covenant
requirements.  Capital management may include subordinated debt issuance,  share
repurchase and stock and cash dividends.

On April 26, 2005, the Board of Directors authorized a share repurchase program,
which  replaced a  previously  authorized  program.  The  maximum of two million
common  shares  may be  repurchased.  The  specific  timing and amount of shares
repurchased will vary based on market conditions, securities law limitations and
other  factors.  Repurchases  may be made over time in open market or  privately
negotiated   transactions.   The   repurchase   programs  may  be  suspended  or
discontinued  at any time without  prior  notice.  During the second  quarter of
2007, the Company repurchased 18,783 common shares at an average price of $51.49
per share.  The Company may  repurchase  1.7 million common shares in the future
under this program.

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

BOK  Financial  and  its  subsidiary   banks  are  subject  to  various  capital
requirements  administered by federal agencies.  Failure to meet minimum capital
requirements   can  result  in  certain   mandatory   and  possibly   additional
discretionary   actions  by  regulators  that  could  have  material  impact  on
operations.  These capital requirements include quantitative measures of assets,
liabilities, and off-balance sheet items. The capital standards are also subject
to qualitative judgments by the regulators.

For a banking institution to qualify as well capitalized,  its Tier 1, Total and
Leverage  capital ratios must be at least 6%, 10% and 5%,  respectively.  All of
the Company's banking  subsidiaries  exceeded the regulatory  definition of well
capitalized.  The capital ratios for BOK Financial on a  consolidated  basis are
presented in Table 21.

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

Off-Balance Sheet Arrangements

During 2002, BOK Financial  agreed to a limited price  guarantee on a portion of
the common  shares issued to purchase of Bank of  Tanglewood.  Any holder of BOK
Financial common shares issued in this acquisition may annually make a claim for
the excess of the  guaranteed  price over the actual  sales  price of any shares
sold during a 60-day period after each of the first five anniversary dates after
October 25, 2002.  The final  anniversary  date of this guarantee is October 25,
2007.  The maximum annual number of shares subject to this guarantee is 210,069.
The price guarantee is non-transferable  and  non-cumulative.  BOK Financial may
elect, in its sole discretion,  to issue additional shares of common stock or to
pay cash to satisfy any obligation under the price  guarantee.  The Company will
have no obligation to issue additional  common shares or pay cash to satisfy any
benchmark  price  protection  obligation  if the  market  value per share of BOK
Financial common stock remains above the highest benchmark price of $42.53.  The
closing  price of BOK  Financial  common  stock on June 30,  2007 was $53.42 per
share.

Market Risk

Market risk is a broad term for the risk of economic loss due to adverse changes
in the fair value of a financial instrument.  These changes may be the result of
various factors,  including interest rates,  foreign exchange prices,  commodity
prices or equity prices.  Financial  instruments that are subject to market risk
can be  classified  either as held for trading or held for  purposes  other than
trading.

BOK Financial is subject to market risk primarily  through the effect of changes
in interest  rates on both its assets held for  purposes  other than trading and
trading assets.  The effects of other changes,  such as foreign  exchange rates,
commodity  prices or equity  prices do not pose  significant  market risk to BOK
Financial. BOK Financial has no material investments in assets that are affected
by  changes  in  foreign  exchange  rates or equity  prices.  Energy  derivative
contracts,  which are  affected  by changes in  commodity  prices,  are  matched
against offsetting contracts as previously discussed.

Responsibility  for  managing  market  risk  rests  with the  Asset /  Liability
Committee  that operates  under policy  guidelines  established  by the Board of
Directors. The acceptable negative variation in net interest revenue, net income
or economic value of equity due to a specified  basis point increase or decrease
in interest  rates is generally  limited by these  guidelines to +/- 10%.  These
guidelines also set maximum levels for short-term borrowings, short-term assets,
public funds, and brokered deposits,  and establish minimum levels for unpledged
assets,  among  other  things.  Compliance  with these  guidelines  is  reviewed
monthly.


Interest Rate Risk - Other than Trading

BOK Financial  has a large portion of its earning  assets in variable rate loans
and a large portion of its  liabilities in demand deposit  accounts and interest
bearing  transaction  accounts.  Changes in interest rates affect earning assets
more rapidly than interest bearing liabilities in the short term. Management has
adopted  several  strategies  to  position  the  balance  sheet to be neutral to
interest rate changes.  As previously  noted in the Net Interest Revenue section
of this report,  management acquires securities that are funded by borrowings in
the capital markets.  The average duration of these securities is expected to be
approximately  2.8  years  based on a range  of  interest  rate  and  prepayment
assumptions.

BOK  Financial  also uses  interest  rate swaps in managing  its  interest  rate
sensitivity. These products are generally used to more closely match interest on
certain  variable-rate loans with funding sources and long-term  certificates of
deposit

 28

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

The effectiveness of these strategies in managing the overall interest rate risk
is evaluated through the use of an asset/liability model. BOK Financial performs
a sensitivity  analysis to identify more dynamic  interest rate risk  exposures,
including  embedded option positions,  on net interest  revenue,  net income and
economic value of equity.  A simulation  model is used to estimate the effect of
changes in interest rates over the next 12 and 24 months based on eight interest
rate  scenarios.  Two  specified  interest  rate  scenarios are used to evaluate
interest  rate risk against  policy  guidelines.  The first  scenario  assumes a
sustained  parallel 200 basis point  increase and the second assumes a sustained
parallel 200 basis point decrease in interest rates. The Company also performs a
sensitivity  analysis  based on a "most likely"  interest rate  scenario,  which
includes non-parallel shifts in interest rates. An independent source is used to
determine the most likely interest rate scenario.

The Company's  primary interest rate exposures  included the Federal Funds rate,
which affects short-term borrowings, and the prime lending rate and LIBOR, which
are the basis for much of the variable-rate loan pricing. Additionally, mortgage
rates directly affect the prepayment speeds for  mortgage-backed  securities and
mortgage servicing rights.  Derivative financial instruments and other financial
instruments   used  for  purposes  other  than  trading  are  included  in  this
simulation.  The model incorporates assumptions regarding the effects of changes
in interest rates and account balances on indeterminable maturity deposits based
on a combination  of historical  analysis and expected  behavior.  The impact of
planned  growth and new  business  activities  is factored  into the  simulation
model.  The  effects  of  changes  in  interest  rates on the value of  mortgage
servicing  rights are excluded from Table 22 due to the extreme  volatility over
such a large rate range.  The effects of interest  rate  changes on the value of
mortgage  servicing  rights and  securities  identified  as economic  hedges are
presented in the Lines of Business - Mortgage Banking section of this report.

The  simulations  used to manage  market risk are based on numerous  assumptions
regarding  the effects of changes in interest  rates on the timing and extent of
repricing  characteristics,  future  cash  flows and  customer  behavior.  These
assumptions  are  inherently  uncertain  and,  as a  result,  the  model  cannot
precisely estimate net interest revenue,  net income or economic value of equity
or  precisely  predict  the  impact  of higher  or lower  interest  rates on net
interest  revenue,  net income or economic value of equity.  Actual results will
differ from simulated results due to timing, magnitude and frequency of interest
rate changes, market conditions and management strategies, among other factors.

Trading Activities

BOK  Financial  enters  into  trading  activities  both as an  intermediary  for
customers and for its own account.  As an intermediary,  BOK Financial will take
positions in securities, generally mortgage-backed securities, government agency
securities,  and municipal  bonds.  These securities are purchased for resale to
customers,  which include individuals,  corporations,  foundations and financial
institutions.  BOK Financial will also take trading  positions in U.S.  Treasury
securities,  mortgage-backed  securities,  municipal bonds and financial futures
for its own account.  These positions are taken with the objective of generating
trading profits. Both of these activities involve interest rate risk.

A variety  of  methods  are used to manage  the  interest  rate risk of  trading
activities.  These  methods  include  daily  marking of all  positions to market
value,  independent  verification of inventory pricing,  and position limits for
each trading activity.  Hedges in either the futures or cash markets may be used
to reduce the risk associated with some trading programs.

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

 29

VAR is calculated  based upon  historical  simulations  over the past five years
using a variance / covariance matrix of interest rate changes.  It represents an
amount of market  loss that is likely to be  exceeded  only one out of every 100
two-week periods.  Trading  positions are managed within guidelines  approved by
the Board of Directors.  These guidelines limit the VAR to $1.8 million. At June
30,  2007,  the VAR was $558  thousand.  The  greatest  value at risk during the
quarter was $1.2 million.


Controls and Procedures

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


Forward-Looking Statements

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

Notes to Consolidated Financial Statements (Unaudited)

(1) Accounting Policies

Basis of Presentation

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

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

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

Newly Adopted and Pending Accounting Policies

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

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

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

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

 35

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

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

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

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

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


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

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

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

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

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

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

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

(5) Mortgage Banking Activities

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

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

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

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

(11)  Contingent Liabilities

AXIA Investment Management,  Inc. ("AXIA"), a wholly-owned subsidiary of BOk, is
the administrator to and investment  advisor for the American  Performance Funds
("AP  Funds").  AP  Funds  is  a  diversified,   open-ended  investment  company
established in 1987 as a business trust under the Investment Company Act of 1940
(the "1940 Act"). AP Fund's products are offered to customers,  employee benefit
plans,  trusts  and the  general  public in the  ordinary  course  of  business.
Approximately  98% of AP  Fund's  assets  of  $3.6  billion  are  held  for  BOK
Financial's clients.

 41

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

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

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

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


(12) Financial Instruments with Off-Balance Sheet Risk

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

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

                                               June 30,
