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

Performance Summary

BOK Financial Corporation ("BOK Financial" or the "Company") reported net income
of $50.5  million,  or $0.75 per diluted  share for the second  quarter of 2005,
compared with $45.5  million,  or $0.68 per diluted share for the second quarter
of 2004. The annualized returns on average assets and shareholders'  equity were
1.31% and 14.05%,  respectively,  for the second quarter of 2005,  compared with
returns of 1.32% and  14.36%,  respectively,  for the same  period in 2004.  The
increase  in net  income  was  attributed  primarily  to growth in net  interest
revenue and fees and  commission  revenue and a reduction in the  provision  for
credit  losses.  Revenue  growth was  partially  offset by  increased  operating
expenses  and  lowered  value of mortgage  servicing  rights.  The Company  also
recognized  pre-tax  gains of $5.9 million on sales of its interest in an office
building and a portfolio of residential mortgage loans.

Net interest  revenue  increased  $7.3 million or 7% over the second  quarter of
2004 due  primarily to loan growth.  Average  outstanding  loan balances for the
second  quarter of 2005  increased  $793 million or 11%  compared  with the same
period of 2004.  Fees and commissions  revenue  increased $6.7 million or 8% due
primarily to trust fees. The provision for credit losses  decreased $2.0 million
compared to the second  quarter of the  previous  year due to  continued  strong
credit quality.  Operating  expenses,  excluding the provision for impairment of
mortgage  servicing  rights increased $9.1 million or 8% due primarily to growth
in personnel costs. The value of mortgage  servicing rights depreciated due to a
50 basis  point  decrease in  mortgage  commitment  rates since the start of the
second quarter.  The reduced value of servicing  rights,  net of gains or losses
recognized on financial  instruments  held as an economic  hedge,  resulted in a
$3.7 million  decrease in pre-tax income for the second quarter of 2005 compared
with a $752 thousand increase for the same period of 2004.

The Company  issued $150 million of 10-year  subordinated  debt through its lead
banking  subsidiary,  Bank of Oklahoma,  and completed the acquisition of Valley
Commerce Bank in Phoenix, Arizona during the second quarter of 2005. Proceeds of
the subordinated debt provided  additional  capital to support future growth and
permitted  repayment  of  short-term  borrowings.  Valley  Commerce,  which  was
acquired  for $32 million  cash,  added $93 million in loans and $110 million in
deposits.  Effective August 12, 2005,  Valley Commerce Bank will be renamed Bank
of Arizona, N.A.

Year-to-date  net income for 2005  totaled  $102.5  million or $1.53 per diluted
share  compared  with net income of $84.7 million or $1.27 per diluted share for
the  first  six  months of 2004.  The  increase  in net  income  was  attributed
primarily  to an $11.7  million  increase  in net  interest  revenue  and a $9.8
million  increase in fees and commission  revenue,  combined with a $7.0 million
reduction in the provision for credit losses.

Results of Operations

Net Interest Revenue

Tax-equivalent  net  interest  revenue  totaled  $113.8  million  for the second
quarter of 2005  compared  with $106.3  million for 2004.  The  increase was due
primarily to a $886 million  increase in average earning  assets.  The growth in
average earning assets included a $793 million,  or 11%, increase in loans and a
$179 million increase in securities. Growth in average earning assets was funded
primarily by a $594 million increase in short-term borrowings and a $389 million
increase  in  deposits.  Table 2 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 3.45% for the second quarter of 2005,  compared with 3.46%
for both the second  quarter of 2004 and the first quarter of 2005. Net interest
margin for the first  quarter of 2005  included a 4 basis point benefit from the
collection of foregone  interest on a non-performing  loan and fees related to a
large loan  transaction.  Yields on average  earning  assets  continued to trend
upwards  due to the effect of rising  short-term  interest  rates.  The yield on
average  earning assets was 5.68%,  up 83 basis points  compared with the second
quarter of 2004 and 22 basis points over the first quarter of 2005. Average loan
yields were 6.40%,  an increase of 126 basis  points over the second  quarter of
2004 and 34 basis points over the preceding quarter. The tax-equivalent yield on
securities was 4.36% for the second quarter of 2005, compared with 4.30% for the
second  quarter of 2004 and 4.36% for the first  quarter of 2005.  Rates paid on
average interest-bearing liabilities during the second quarter of 2005 increased
92 basis  points  over  the same  period  of 2004 and 18 basis  points  over the
preceding quarter.  Increases in rates paid on deposit accounts continued to lag
behind the increases in loan yields.  The cost of interest  bearing deposits was
2.34% for the second quarter of 2005, up 55 basis points from the same period in
2004 and 6 basis  points from the  preceding  quarter.  The benefit  provided by
non-interest  bearing funding sources,  primarily demand deposits,  was 35 basis
points for the second  quarter of 2005,  compared  with 27 basis  points for the
second  quarter of 2004 and 40 basis points for the first  quarter of 2005,  due
primarily to a decrease in average demand deposit account balances. The decrease
in demand  deposit  accounts  included  funds  transferred  to  interest-bearing
transaction accounts during the second quarter of 2005.

The  overall  objective  is  to  position  the  Company's  balance  sheet  to be
essentially  neutral  to  changes  in  interest  rate.  A large  portion  of the
commercial  loan  portfolio  is  either  variable  rate or fixed  rate that will
reprice within one year.  These loans are funded  primarily by deposit  accounts
that are either  non-interest  bearing,  or that  reprice  more  slowly than the
loans. The result is a balance sheet that is asset  sensitive,  which means that
assets  generally  reprice more quickly than  liabilities.  Among the strategies
used to achieve a  rate-neutral  position,  the  Company  purchases  fixed-rate,
mortgage-backed  securities  and funds  them  with  short-term  borrowings.  The
effective duration of these securities is expected to be approximately 2.8 years
based on a range of interest rate and prepayment assumptions. The funds borrowed
to  purchase   these   securities   generally   reprice   within  90  days.  The
liability-sensitive   nature  of  this  strategy   provides  an  offset  to  the
asset-sensitive characteristics of the loan portfolio.

Short-term interest rates have increased more than long-term interest rates. The
yield curve  resulting  from these rate  changes  has  flattened.  Although  the
Company's  policy is to position the balance sheet to be essentially  neutral to
rate changes, the flattened yield curve, along with competitive pressure on loan
and deposit pricing, may reduce the net interest margin.

Derivative instruments are also used to manage interest rate risk. Interest rate
swaps  with a  combined  notional  amount of $432  million  convert  fixed  rate
liabilities to floating rate based on LIBOR.  The purpose of these  derivatives,
which  generally  have been  designated as fair value  hedges,  is to reduce the
asset-sensitive nature of the balance sheet. Interest rate swaps with a notional
amount of $100 million convert  prime-based  loans to fixed rate. The purpose of
these  derivatives,  which have been designated as cash flow hedges,  also is to
reduce the asset-sensitive nature of the balance sheet.

The  effectiveness of these strategies is reflected in the overall change in net
interest revenue due to changes in interest rates as shown in Table 1 and in the
interest rate  sensitivity  projections  as shown in Market Risk section of this
report.  Changes in net  interest  revenue  due to changes  in  interest  rates,
pricing  spreads and the timing of when assets and  liabilities  reprice are all
captured in the Yield/Rate column in Table 1.

Other Operating Revenue

Other operating revenue increased $25.3 million compared with the second quarter
of 2004 due  primarily  to a $12.8  million  increase  in net gains or losses on
securities and derivatives and a $5.9 million  increase in gains on asset sales.
Fees and  commission  revenue,  which is  included in other  operating  revenue,
increased $6.7 million or 8%. Diversified sources of fees and commission revenue
are a significant part of the Company's business strategy and represented 43% of
total revenue,  excluding gains and losses on securities,  derivatives and asset
sales,  for both the second quarters of 2005 and 2004. The Company believes 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 and can directly or indirectly affect income.

Fees and commissions revenue

Trust fees  increased  $2.3 million or 17% for the second  quarter of 2005.  The
fair value of all trust relationships managed by the Company, which is the basis
for a significant  portion of trust fees  increased to $26.0 billion at June 30,
2005 compared with $22.9 billion at June 30, 2004.

Service  charges on deposit  accounts  grew $1.4 million or 6% compared with the
second quarter of 2004.  Overdraft fees grew 18% or $2.5 million.  The volume of
overdraft items processed increased during the second quarter after declining in
the previous  two  quarters.  Additionally,  the per item  overdraft  charge was
increased  during the second quarter of 2005. The increase in overdraft fees was
partially  offset by a $1.1 million or 13% decrease in service  charge  revenue.
This decrease  reflected an increase in earnings credit  available to commercial
deposit  customers.  The earnings  credit,  which provides a non-cash method for
commercial customers to pay for deposit services,  increases when interest rates
rise.

Transaction  card  revenue  increased  $1.2 million or 7% due to growth in check
card revenue. Continued growth in transaction volume provided the increase.

 5

Other  revenue for the second  quarter of 2005  included  $1.4 million from fees
earned on margin  accounts.  The Bank of Oklahoma is required to deposit  margin
funds with other  institutions as part of its derivatives and trading  programs.
Margin deposits,  which are included in other assets,  averaged $204 million for
the second  quarter of 2005 compared with $61 million for the second  quarter of
2004.

Mortgage banking revenue,  which is discussed more fully in the Line of Business
- - Mortgage  Banking  section of this  report  increased  $995  thousand,  or 13%
compared  with the second  quarter  of 2004.  Net gains on  mortgage  loans sold
increased  $1.4  million.  Servicing  revenue  decreased  $413 thousand due to a
decrease in the average outstanding balance of loans serviced.

Brokerage  and trading  revenue  decreased  $762  thousand or 7%.  Revenue  from
securities  trading  activities  decreased  $3.2  million  or 46% due to reduced
fixed-income  securities  trading volumes.  This reduction was largely offset by
increases  in customer  hedging  revenue and retail  brokerage  sales.  Customer
hedging  revenue  increased  $2.0  million.  Volatility  in the  energy  markets
prompted  energy  customers to more actively hedge their gas and oil production.
Revenue  from retail  sales of mutual  funds,  annuities  and  similar  products
increased $446 thousand.

Securities and derivatives

BOK Financial  recorded net gains of $2.0 million on securities and  derivatives
for the second quarter of 2005. These amounts included net gains of $3.4 million
on  financial  instruments  held as economic  hedges of the  mortgage  servicing
rights.  The  Company's  use of  securities  as an  economic  hedge of  mortgage
servicing  rights is  more-fully  discussed  in the Line of  Business - Mortgage
Banking section of this report. During the second quarter of 2004, BOK Financial
recognized net losses on securities and derivatives of $10.8 million,  including
net losses of $10.1 million on securities held as economic hedges.

Gain on sales of assets

The Company realized net gains of $5.9 million during the second quarter of 2005
from  sales of  assets.  A gain of $4.7  million  resulted  from the sale of its
interest in an Oklahoma  City office  building.  A net gain of $1.2  million was
recognized from the sale of $118 million of loans from the residential  mortgage
loan portfolio.  In addition to a cash premium received on the sale, the Company
retained  both the right to service the loans and a recourse  obligation  to the
purchaser in case of default by the borrowers.

Year-to-date operating revenue summary

Year to date other operating  revenue for 2005 increased $23.7 million,  or 16%.
This increase  included a $9.9 million  increase in fees and commission  revenue
and a $13.8 million  increase in net gains on securities,  derivatives and asset
sales. The increase in fees and commission revenue was due primarily from growth
in trust fees and  transaction  card revenue and  reflected  the growth in trust
assets managed by the Company and card processing volumes.

Other Operating Expense

Other  operating  expense for the second quarter of 2005 totaled $126.0 million,
up $27.0 million,  or 27% from the same period of 2004.  This increase  resulted
primarily  from an $18.0 million  increase in the  provision  for  impairment of
mortgage  servicing  rights.  Additionally,  operating  expenses  for the second
quarter of 2005 included $1.6 million for Bank of Arizona, which was acquired on
April 7, 2005.

Personnel expense

Personnel  expense totaled $65.3 million for the second quarter of 2005 compared
with $59.8  million for the second  quarter of 2004.  The  increase in personnel
expense  included $1.1 million from expansion into the Phoenix  market.  Regular
compensation expense totaled $41.0 million, a $4.7 million, or 13% increase over
2004. The increase in regular  compensation expense was due to an 8% increase in
average regular compensation per full-time equivalent employee and a 5% increase
in average staffing.

Incentive   compensation  decreased  $1.1  million,  or  8%  to  $12.9  million.
Stock-based compensation expense increased $1.7 million. Much of this expense is
related to  stock-based  compensation  that is recognized  as liability  awards.
Compensation  expense for these  awards is based on the excess of the fair value
of BOK Financial common stock over a set exercise price.  Incentive compensation
expense  for these  awards  varies  directly  with  changes in the fair value of
BOKF's  common  stock,  which  increased  during the  quarter.  Other  incentive
compensation  expenses  decreased $3.1 million due to reductions in the Oklahoma
corporate banking and wealth management lines of business.

Employee  benefit  expenses  increased  $1.9 million,  or 20% to $11.4  million.
Employee insurance costs increased $802 thousand, or 28% due primarily to growth
in medical  claims.  The Company  self-insures a portion of its employee  health
care coverage.  The remaining  increase in employee  benefit  expenses  resulted
primarily from payroll taxes and retirement benefits.

Data processing and communications expense

Data  processing  and  communication  expenses  increased  $1.1  million,  or 7%
compared to 2004. This expense consists of two broad categories, data processing
systems and transaction  card  processing.  Transaction  card  processing  costs
increased  $485  thousand  or 8% due  to  growth  in  processing  volumes.  Data
processing systems costs increased $626 thousand,  or 7% due primarily to higher
software amortization and maintenance costs.

Other expenses

Other  expenses  for the second  quarter of 2005 totaled  $7.4  million,  a $1.8
million  increase over the same period of 2004.  Recruiting  expenses  increased
$1.2 million as the Company continued  expansion in regional markets,  trust and
executive management.

Year-to-date operating expense summary

Operating  expenses for the first half of 2005 totaled $228.2  million  compared
with $215.4  million for the first half of 2004.  Provision  for  impairment  of
mortgage servicing rights increased $8.6 million due to changes in mortgage loan
commitment rates and related prepayment speeds. Operating expenses for the first
half of 2004  included  a charge  of $4.1  million  for the cost of  appreciated
securities  contributed  to  the  BOK  Charitable  Foundation.  Personnel  costs
increased  $5.8 million,  or 5%. This increase  included $6.9 million,  or 9% of
regular  compensation  expense  and $3.7  million  of  employee  benefit  costs,
partially offset by a $4.8 million decrease in incentive compensation expense.

Income Taxes

Income tax expense was $28.6  million for the second  quarter of 2005,  compared
with $25.9 million for 2004.  This  represented  36% of book taxable  income for
both quarters.  Year to date,  income tax expense was $58.2  million,  or 36% of
book  taxable  income for 2005 and $46.3  million,  or 35% for 2004.  Income tax
expense  for  2004  was  reduced  by  $1.2  million  from  the  contribution  of
appreciated securities to the BOk Charitable Foundation.

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,  which were a core  business of Colorado
State Bank and Trust, are included in regional banking. Regional banking consist
primarily of corporate and consumer  banking  activities in the respective local
markets.  In  addition  to its  lines of  business,  BOK  Financial  has a funds
management  unit.  The  primary  purpose of this unit is to manage  the  overall
liquidity  needs and interest  rate risk of the  company.  Each line of business
borrows funds from and provides funds to the funds  management unit as needed to
support their operations.

 8

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 third-party  developed
capital  allocation  model that reflects  management's  assessment of risk. This
model  assigns  capital based upon credit,  operating,  interest rate and market
risk inherent in the 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 loss history where possible.  Additional  capital is assigned to the regional
banking line of business based on the Company's investment in those entities.

Oklahoma Corporate Banking

The Oklahoma  Corporate  Banking Division  provides loan and lease financing and
treasury and cash  management  services to  businesses  throughout  Oklahoma and
certain  relationships in surrounding states. In addition to serving the banking
needs of small  businesses,  middle  market and larger  customers,  the Oklahoma
Corporate  Banking  Division has specialized  groups that serve customers in the
energy, agriculture, healthcare and banking/finance industries, and includes the
TransFund  network.  The Oklahoma  Corporate Banking Division  contributed $22.3
million or 44% to  consolidated  net income for the second quarter of 2005. This
compares to $16.1 million or 35% of consolidated  net income for the same period
of 2004.  Net income  provided by this  division  included $2.9 million from the
after-tax  benefit  from the sale of an  interest  in an  Oklahoma  City  office
building.  Average  assets  increased  $460 million or 10% due primarily to loan
growth.  A  reduction  in  net  loan  charge-offs  improved  Oklahoma  Corporate
Banking's  performance by $1.9 million.  This improvement in credit quality also
reduced economic capital allocated to this unit.

Oklahoma Consumer Banking

The Oklahoma Consumer Banking Division provides a full line of deposit, loan and
fee-based  services  to  customers   throughout   Oklahoma  through  four  major
distribution channels:  traditional branches,  supermarket branches, the 24-hour
ExpressBank  call  center and the  Internet.  Additionally,  the  division  is a
significant  referral  source for the Bank of Oklahoma  Mortgage  Division ("BOk
Mortgage") and BOSC's retail brokerage  division.  The Consumer Banking Division
contributed  $5.4  million  or 11% to  consolidated  net  income  for the second
quarter of 2005. This compares to $2.8 million or 6% of consolidated  net income
in 2004. Net interest revenue  increased $4.0 million due largely to an increase
in transfer pricing credit to business units that provide lower-costing funds to
the Company.

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

 10

loans.  Consolidated  mortgage  banking  revenue,  which  is  included  in other
operating  revenue,  increased  $995  thousand,  or 13% compared with the second
quarter  of  2004.  Mortgage  banking  activities  incurred  a net  loss of $309
thousand for the second quarter of 2005 compared with net income of $1.8 million
in 2004.  Net income for the second  quarter of 2005 included $753 thousand from
the sale of mortgage loans from the residential loan portfolio.

Mortgage banking activities  consisted of two sectors,  loan production and loan
servicing.  The loan  production  sector  generally  performs best when mortgage
rates are relatively low and loan origination volumes are high. Conversely,  the
loan servicing sector generally performs best when mortgage rates are relatively
high and  prepayments  are low.  Mortgage  loan  commitment  rates fell 50 basis
points during the second  quarter of 2005.  This  decrease in  commitment  rates
improved the pricing of loans sold during the quarter and  increased  the amount
of loan  applications  in process at quarter  end. It also  reduced the value of
mortgage loan servicing rights due to higher expected prepayment speeds.

Loan Production Sector

Loan  production  revenue  totaled $5.1 million for the second  quarter of 2005,
including $4.6 million of capitalized  mortgage  servicing  rights,  compared to
loan  production  revenue of $4.3  million in 2004,  including  $3.6  million of
capitalized  mortgage  servicing rights. The increase in loan production revenue
was due to improved  pricing of loans sold.  Mortgage loans funded in the second
quarter  of 2005  totaled  $185  million  compared  with $197  million  in 2004.
Approximately 69% of the loans funded during 2005 were to borrowers in Oklahoma.
Pre-tax income from loan production  totaled $1.8 million for the second quarter
of 2005 compared with $2.5 million for the second  quarter of 2004. The pipeline
of mortgage loan applications totaled $292 million at June 30, 2005, compared to
$250 million at March 31, 2005 and $232 million at June 30, 2004.

Loan Servicing Sector

The loan  servicing  sector had a pre-tax  loss of $3.9  million  for the second
quarter of 2005  compared  with  pre-tax  income of $307  thousand  for the same
period of 2004. A 50 basis point decrease in mortgage  interest rates during the
second quarter of 2005 reduced the value of servicing rights. This resulted in a
$7.1  million  provision  for  impairment  of mortgage  servicing  rights.  This
provision was partially offset by $3.4 million of gains on financial instruments
held as an  economic  hedge of the value of the  servicing  rights.  During  the
second  quarter of 2004,  the allowance for  impairment of servicing  rights was
decreased  by $10.9  million.  Net losses of $10.1  million were  recognized  on
financial instruments designated as an economic hedge.

Servicing  revenue  totaled $4.1 million in the second  quarter of 2005 compared
with $4.5 million in 2004.  The decrease in servicing  revenue was due primarily
to a  lower  outstanding  principal  balance  of  loans  serviced.  The  average
outstanding balance of loans serviced was $3.7 billion during the second quarter
of 2005  compared to $4.0 billion  during 2004.  The decrease in loans  serviced
reflected both the continued  refinancing  of mortgage loans and  curtailment of
purchases  of  mortgage  loan  servicing.   Annualized   servicing  revenue  per
outstanding  loan  principal was 44 basis points in the second  quarter of 2005,
compared with 45 basis points in 2004.

Amortization  of mortgage  servicing  rights,  which is  included  in  operating
expense, was $3.0 million in 2005 compared to $3.8 million in 2004. Amortization
expense is determined in proportion to the estimated future cash flows that will
be generated by the mortgage  servicing  rights.  The reduction in  amortization
expense reflected an expectation of lower loan prepayment speeds.

BOK Financial  designates a portion of its  securities  portfolio as an economic
hedge against the risk of loss on its mortgage servicing rights. Mortgage-backed
securities  and U.S.  government  agency  debentures  are  acquired  and held as
available for sale when prepayment  risks exceed certain  levels.  Additionally,
interest rate  derivative  contracts may also be designated as an economic hedge
of the risk of loss on  mortgage  servicing  rights.  Because the fair values of
these  instruments  are  expected  to vary  inversely  to the fair  value of the
servicing  rights,  they are expected to  partially  offset  risk.  However,  no
special  hedge  accounting  treatment  is  applicable  to  either  the  mortgage
servicing rights or the financial  instruments  designated as an economic hedge.
Securities may be sold and gains or losses realized when necessary to offset the
impairment provision of the mortgage servicing rights. Derivative contracts used
to hedge  mortgage  servicing  rights are carried at fair value with  changes in
fair value recognized in earnings.

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

At June 30, 2005,  financial  instruments with a fair value of $151 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, 2005, the pre-tax  results of this modeling
on reported earnings were:


Table 8 - Interest Rate Sensitivity - Mortgage Servicing
(Dollars in Thousands)
                                           50 bp increase   50 bp decrease
Anticipated change in:
Fair value of mortgage servicing rights        $ 5,988      $  (10,368)
Fair value of hedging securities                (5,061)          5,696
                                          ----------------- ----------------
   Net                                     $      927       $   (4,672)
                                          ----------------- ----------------

Table 8 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 $6.0 million while a 50 basis point decrease is
expected to reduce value by $10.4 million. This considers that there is an upper
limit to the 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.

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.  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
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.

Wealth management  contributed $3.4 million or 7% to consolidated net income for
the second quarter of 2005.  This compared to $3.0 million or 7% of consolidated
net income for the same period of 2004.

Trust and private financial  services provided $3.5 million of net income in the
second quarter of 2005, a 57% increase over 2004. At June 30, 2005 and 2004, the
wealth  management  line of  business  was  responsible  for trust  assets  with
aggregate  market  values of $24 billion and $21  billion,  respectively,  under
various fiduciary  arrangements.  The growth in trust assets reflected increased
market value of assets managed in addition to new business  generated during the
year. The Company has sole or joint discretionary authority over $8.6 billion of
trust  assets at June 30, 2005  compared to $7.6 billion of trust assets at June
30, 2004.

Brokerage  and  trading  activities  incurred a net loss of $97  thousand in the
second  quarter of 2005  compared  to net income of $813  thousand in the second
quarter of 2004. Trading revenue decreased $1.1 million due primarily to reduced
fixed-income  securities  trading  volumes.  This revenue  reduction was largely
offset by increases in customer hedging revenue and retail sales.

Regional Banking

Regional  Banking  consists  primarily of the corporate and  commercial  banking
services  provided  by Bank of Texas,  Bank of  Albuquerque,  Bank of  Arkansas,
Colorado State Bank and Trust and Bank of Arizona in their  respective  markets.
They also include fiduciary  services provided by Colorado State Bank and Trust.
Small  businesses and  middle-market  corporations  are Regional Banking primary
customer  focus.   Regional  Banking   contributed   $18.3  million  or  36%  to
consolidated  net income during the second  quarter of 2005.  This compares with
$13.5  million or 30% of  consolidated  net income for the same  period in 2004.
Growth in net income  contributed  by the  regional  banks came  primarily  from
operations in Texas and New Mexico.  Net income for 2005 in Texas and New Mexico
increased $3.2 million and $1.7 million, respectively.

 13

Growth in net income from Texas operations  resulted  primarily from an increase
in net interest revenue.  Average earning assets increased $166 million. Average
loans  increased $267 million,  or 15% while funds sold to the funds  management
unit decreased $88 million. Average deposits increased $99 million, or 4%.

The increase in net income from New Mexico  operations was also based largely on
an increase in net  interest  revenue.  Average  earning  assets  decreased  $15
million,  or 1%.  However,  the mix of earning  assets  improved.  Average loans
increased  $71  million  or 13% while  funds sold to the funds  management  unit
decreased $87 million.  Average  deposits in the New Mexico market increased $67
million or 8%.

In addition,  the Company continued expansion efforts in Colorado.  A new office
which  offers  trust  products  was  opened in Salt Lake City  during the second
quarter  of  2005  and  additional  commercial  lending  staff  was  added.  The
conversion  of Bank of Arizona's  data  processing  systems is scheduled for the
third quarter of 2005.  This  conversion will increase the scope of products and
services  offered in the  Phoenix  market.  Bank of Arizona  operating  expenses
included  $266 thousand of  amortization  of  intangible  assets.  The Company's
policy is to amortize core deposit  intangible  assets over the expected life of
the acquired  deposits using an accelerated  amortization  method.  The weighted
average life of the acquired deposits is approximately five years.

Financial Condition

Securities

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

The  amortized  cost of available  for sale  securities at June 30, 2005 totaled
$4.9  billion  compared  with $4.7  billion at March 31,  2005.  Mortgage-backed
securities   continued  to  represent   substantially  all  available  for  sale
securities.  As previously discussed in the Net Interest Revenue section of this
report,  the Company  holds  mortgage  backed  securities  as part of an 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. The Company  evaluates 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 June 30, 2005 and 3.2 years at March 31, 2005.

Net unrealized  losses on available for sale  securities  totaled $46 million at
June 30, 2005 compared  with $80 million at March 31, 2005.  The decrease in net
unrealized  losses was due primarily to falling  interest  rates.  The aggregate
gross  amount  of  unrealized  losses  at June 30,  2005  totaled  $52  million.
Management  evaluated the securities with unrealized  losses to determine if 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.  It is  believed,  based on  currently  available
information and the Company's  evaluation,  that the unrealized  losses in these
securities were temporary.

Loans

The  aggregate  loan  portfolio at June 30, 2005 totaled  $8.5  billion,  a $429
million or 21% annualized increase since March 31, 2005.

The commercial  loan portfolio  increased $223 million during the second quarter
of  2005.  Much of this  increase  was  focused  in the  energy  portion  of the
portfolio,  which  increased  $104  million,  or 8%.  Energy loans  totaled $1.3
billion or 15% of total loans at June 30, 2005.  Approximately  $1.0 billion was
to oil and gas  producers.  The amount of credit  available  to these  customers
generally  depends  on the  value  of  their  proven  energy  reserves  based on
anticipated  prices.  This portion of the energy loan portfolio provided much of
the  quarter's  loan  growth.   Exploration  and  acquisition   activities  have
increased.   Management   believes  that  the  increased  activity  included  an
expectation  that the markets  have set a new  floor for energy  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.  Services comprised 20% of the total loan
portfolio  and included  $278 million of loans to nursing homes and $156 million
of loans to medical  facilities.  Agriculture  included $205 million of loans to
the cattle industry.  Other notable loan  concentrations  by primary industry of
the borrowers are presented in Table 15.

BOK Financial participates in shared national credits when appropriate to obtain
or maintain business relationships with local customers. Shared national credits
are defined by banking  regulators  as credits of more than $20 million and with
three or more  non-affiliated  banks as  participants.  At June  30,  2005,  the
outstanding principal balance of these loans totaled $1.0 billion. Substantially
all is to borrowers with local market relationships.  BOK Financial is the agent
lender in  approximately  22% of its shared national credit  relationships.  The
Company's  lending  policies   generally  avoid  loans  in  which  there  is  no
opportunity  to  maintain  or  achieve  other  business  relationships  with the
customer.

Commercial  real estate loans totaled $1.9 billion or 22% of the loan  portfolio
at June 30,  2005.  The  outstanding  balance of  commercial  real estate  loans
increased $193 million since March 31, 2005.  Construction  and land development
included $416 million for single family  residential  lots and premises,  up $19
million,  or 5% since March 31, 2005. This growth resulted from expanded builder
loans,  primarily in Arizona.  The major  components  of other  commercial  real
estate loans were retail facilities at $334 million and office buildings at $420
million.  Commercial real estate loans secured by office buildings increased $43
million, or 11%, during the quarter.

 17

Residential mortgage loans, excluding loans held for sale, included $341 million
of home equity loans,  $319 million of loans held in  conjunction  with business
relationships,  $235 million of  adjustable  rate  mortgages and $184 million of
loans held for community development. Community development loans decreased $132
million  during the second  quarter  of 2005 due  primarily  to the sale of $118
million  of such  loans.  Consumer  loans  included  $286  million  of  indirect
automobile  loans.  Substantially all of these loans were purchased from dealers
in Oklahoma.

market areas.

Loan Commitments

BOK Financial enters into certain  off-balance sheet  arrangements in the normal
course of business.  These arrangements  included loan commitments which totaled
$3.8 billion and standby  letters of credit  which  totaled $470 million at June
30, 2005. Loan commitments may be unconditional obligations to provide financing
or conditional  obligations that depend on the borrower's  financial  condition,
collateral value or other factors.  Standby letters of credit are  unconditional
commitments to guarantee the  performance of a customer to a third party.  Since
some of these  commitments  are expected to expire before being drawn upon,  the
total commitment amounts do not necessarily represent future cash requirements.

Derivatives with Credit Risk

BOK Financial  offers programs that permit its customers to hedge various risks,
including  fluctuations in energy and cattle prices,  interest rates and foreign
exchange rates. Each of these programs work essentially the same way. Derivative
contracts are executed between the customers and BOk.  Offsetting  contracts are
executed between BOk and selected counterparties to minimize the risk 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 BOk as compensation  for  administrative  costs,  credit
risk and profit.

These  programs  create  credit risk for  potential  amounts due to BOk 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 limit  the  maximum  exposures  to  individual  customers.
Customers may also be required to provide margin collateral to further limit the
Company's 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  and
approved by the Asset / Liability  Committee.  Margin  collateral is required if
the exposure between BOk and any counterparty  exceeds established limits. Based
on declines in the counterparties'  credit rating,  these limits are reduced and
additional margin collateral is required.

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

Derivative contracts are carried at fair value. At June 30, 2005, the fair value
of derivative  contracts  reported as assets under these  programs  totaled $690
million.  This  included  energy  contracts  with fair  values of $664  million,
interest  rate  contracts  with fair values of $13 million and foreign  exchange
contracts with fairs value of $11 million.  The aggregate fair values of related
derivative  contracts reported as liabilities totaled $691 million. At March 31,
2005,  the fair values of assets and  liabilities  reported under these programs
totaled $720 million and $722 million,  respectively.  Approximately  68% of the
fair value of asset  contracts  was with  customers.  The  credit  risk of these
contracts is generally backed by energy  production.  The remaining 32% was with
counterparties.  The maximum net exposure to any single customer or counterparty
totaled $82 million.

Summary of Loan Loss Experience

The reserve for loan losses, which is available to absorb losses inherent in the
loan  portfolio,  totaled  $109  million  at June 30,  2005 and March 31,  2005,
compared with $115 million at June 30, 2004.  These amounts  represented  1.29%,
1.35% and 1.54% of outstanding loans, excluding loans held for sale, at June 30,
2005, March 31, 2005, and June 30, 2004, respectively.  Losses on loans held for
sale,  principally mortgage loans accumulated for placement into security pools,
are charged to earnings  through  adjustment in the carrying value.  The reserve
for  loan  losses  also   represented   269%  of  the  outstanding   balance  of
nonperforming  loans at June 30, 2005,  compared with 219% at March 31, 2005 and
199% at June 30, 2005.  Net loans charged off during the second  quarter of 2005
totaled $2.3 million, down from $4.9 million for the same period in 2004.

 19

Credit risk from loan  commitments  and letters of credit are  considered in the
evaluation of the adequacy of reserves. A separate reserve for off-balance sheet
credit  risk is  maintained.  Table  17  presents  the  trend  of  reserves  for
off-balance  sheet credit  losses and the  relationship  between the reserve and
loan  commitments.  The  relationship  between the  combined  reserve for credit
losses and  outstanding  loans is also presented to facilitate  comparison  with
peer banks and others who have not  adopted  this  preferred  presentation.  The
provision for credit losses included the combined charge to expense for both the
reserve for loan losses and the reserve for off-balance sheet credit losses. All
losses  incurred  from  lending  activities  will  ultimately  be  reflected  in
charge-offs  against  the  reserve  for  loan  losses.   Losses  on  outstanding
commitments  would occur after the commitment is funded and  collection  efforts
are exhausted.

Specific  impairment  reserves are  determined  through  evaluation of estimated
future cash flows and collateral  value. At June 30, 2005,  specific  impairment
reserves totaled $5.4 million on total impaired loans of $32 million.

 20

Nonspecific  reserves are  maintained  for risks beyond  factors  specific to an
individual  loan or those  identified  through  migration  analysis.  A range of
potential  losses is  determined  for each risk factor  identified.  At June 30,
2005, the ranges of potential losses for the more significant factors were:

General economic conditions - $8.6 million to $12.7 million
Concentration in large loans - $1.6 million to $ 3.2 million

The provision for credit losses  totaled $2.0 million for the second  quarter of
2005,  compared with $2.0 million for the first quarter of 2005 and $4.0 million
for the second quarter of 2004.  Factors considered in determining the provision
for credit losses included a reduction in the outstanding balances of criticized
and classified  loans,  a reduction in the number of past due and  nonperforming
loans,  and a reduction in net losses  incurred.  These  factors were  partially
offset by  concerns  about the effect of changes  in  interest  rates and energy
prices on the  commercial  real  estate  and  commercial  loan  portfolios,  and
increased concentration in loans to residential home builders.

Nonperforming Assets

Information  regarding  nonperforming  assets, which totaled $46 million at June
30,  2005  and  $53  million  at  March  31,  2005 is  presented  in  Table  18.
Nonperforming  assets included  nonaccrual and  renegotiated  loans and excluded
loans 90 days or more past due but still  accruing  interest.  Nonaccrual  loans
totaled $41 million at June 30,  2005 and $50 million at March 31,  2005.  Newly
identified  nonaccruing  loans totaled $3.9 million during the second quarter of
2005.  Nonaccruing loans decreased $7.7 million from a loan that was returned to
accruing  status after a period of  satisfactory  performance,  $3.0 million for
loans charged off or foreclosed, and $2.3 million for cash payments received.

The loan review process also identified  loans that possess more than the normal
amount of risk due to deterioration  in the financial  condition of the borrower
or the value of the  collateral.  Because the borrowers are still  performing in
accordance  with  the  original  terms of the  loan  agreements,  and no loss of
principal  or  interest  is  anticipated,  these  loans  were  not  included  in
Nonperforming Assets. Known information,  however, causes management concerns as
to the  borrowers'  ability  to  comply  with  current  repayment  terms.  These
potential  problem loans totaled $38 million at June 30, 2005 and $41 million at
March 31, 2005. The current  composition  of potential  problem loans by primary
industry  included  healthcare - $11 million,  manufacturing - $9 million,  real
estate - $6 million, services - $5 million and energy - $4 million.

Deposits

Deposit  accounts  represent the Company's  primary funding source.  The Company
competes  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 the 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.

Average  deposits  grew at a 1%  annualized  rate for  second  quarter  of 2005,
excluding $110 million of average deposits  acquired from Bank of Arizona.  Core
deposits,  excluding public funds and brokered  deposits,  grew at an annualized
rate of 3%.  Average core deposits  comprised 52% of total deposits for both the
second and first quarters of 2005.  Deposit  accounts with balances in excess of
$100,000  represented  37% and 36% of total deposits for the second  quarters of
2005 and 2004, respectively.

Average  interest-bearing  transaction  accounts increased $403 million compared
with the preceding  quarter.  Much of this increase was offset by a $310 million
decrease in average demand  deposit  accounts.  Certain  demand deposit  account
balances were transferred to  interest-bearing  transaction  accounts during the
second quarter to better manage the Company's  reserve  position.  This transfer
reduced demand deposits and increased  interest-bearing  transaction accounts by
$129 million in Oklahoma, $197 million in Texas, and $25 million in Colorado.

The distribution of deposit  accounts among principal  markets is shown in Table
19.

Borrowings and Capital

Parent Company

BOK Financial  (parent company) has a $125 million  unsecured  revolving line of
credit  with  certain  banks that  matures in  December  2006.  The  outstanding
principal  balance of this credit  agreement  of $95 million was paid off during
the second  quarter of 2005.  Interest  is based on LIBOR plus a defined  margin
that is determined by the principal balance outstanding and the Company's credit
rating or a base  rate.  The base rate is  defined  as the  greater of the daily
federal  funds  rate plus 0.5% or the prime  rate.  A fee of 20 basis  points is
assessed on the unused committed balance. This credit agreement includes certain
restrictive  covenants  that limit the  Company's  ability to borrow  additional
funds 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, 2005.

The primary source of liquidity for BOK Financial is dividends  from  subsidiary
banks,  which are limited by various  banking  regulations  to net  profits,  as
defined,  for the  preceding  two years.  Dividends  are further  restricted  by
minimum capital  requirements.  Based on the most restrictive  limitations,  the
subsidiary  banks  could  declare  up  to  $175  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 $120
million under this policy.

Shareholders' equity for BOK Financial totaled $1.5 billion at June 30, 2005, an
increase of $66 million since March 31, 2005. Net income provided $50 million to
this  increase and a reduction in net  unrealized  losses on available  for sale
securities  increased  shareholders'  equity by $20 million.  A cash dividend of
$6.6  million or $0.10 per common  share was paid  during the second  quarter of
2005.  The  remaining  increase  in  capital  during  the first  quarter of 2005
resulted primarily from activity in employee stock options.

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.

All of the Company's  Series A Preferred Stock were converted into shares of BOK
Financial  common stock during the second quarter of 2005.  Common shares issued
totaled 6,920,666.

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.  The capital ratios for BOK Financial are presented
in Table 20.

Subsidiary Banks

Bank of Oklahoma issued $150 million of 10-year,  fixed rate  subordinated  debt
during the second quarter of 2005. The cost of the subordinated debt,  including
issuance  discounts and hedge loss is 5.43%. The proceeds of this debt were used
to repay $95 million of BOK Financial's unsecured revolving line of credit.

Off-Balance Sheet Arrangements

During 2002, BOK Financial issued shares of common stock and options to purchase
additional  shares with a fair value of $65 million for its  purchase of Bank of
Tanglewood.  In addition, BOK Financial agreed to a limited price guarantee on a
portion of the shares issued in this purchase.  Pursuant to this guarantee,  any
holder of BOK Financial  common shares issued in this  acquisition  may annually
make a claim for the excess of the  guaranteed  price and the actual sales price
of any  shares  sold  during  a  60-day  period  after  each of the  first  five
anniversary  dates after October 25, 2002.  The maximum  annual number of shares
subject to this  guarantee  is 210,069.  BOK  Financial  may elect,  in its sole
discretion, to issue additional shares of common stock or to pay cash to satisfy
any obligation under the price guaranty.

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,
2005 was $46.12 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  reduce  this  interest  rate  sensitivity.  As
previously noted in the Net Interest Revenue section of this report,  management
acquires securities that are funded by borrowings in the capital markets.  These
securities  have an  expected  duration  of 2.8 years  while the  related  funds
borrowed have an average duration of 90 days.

BOK  Financial  also uses  interest  rate swaps in managing  its  interest  rate
sensitivity. These products are generally used to more closely match interest on
certain  fixed-rate  loans with funding  sources and long-term  certificates  of
deposit  with  earning  assets.  During the second  quarter of 2005 net interest
revenue  decreased $187 thousand from periodic  settlements of these  contracts.
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. A net loss of
$311 thousand was  recognized in 2005 compared to a net gain of $201 thousand in
2004 from  adjustments  of these  swaps and hedged  liabilities  to fair  value.
Credit risk from these swaps is closely monitored as part of the 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 twelve months based on eight

 25

interest rate  scenarios.  Three  specified  interest rate scenarios are used to
evaluate  interest  rate risk.  Two "shock  test"  scenarios,  first  assuming a
sustained  parallel  200 basis point  increase  and second  assuming a sustained
parallel  100 basis  point  decrease  in  interest  rates,  are used to evaluate
interest rate risk against policy guidelines.  Management historically evaluated
interest rate  sensitivity  for a sustained  200 basis point  decrease in rates.
However,  these results are not meaningful in the current low-rate  environment.
Additionally,  interest  rate risk is  evaluated  against a "most  likely"  rate
scenario.  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 21 due to the extreme  volatility over
such a large rate range.  The effects of interest  rate  changes on the value of
mortgage  servicing  rights and  securities  identified  as economic  hedges are
presented in the Lines of Business - Mortgage Banking section of this report.

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

Trading Activities

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

A variety  of  methods  are used to manage  the  interest  rate risk of  trading
activities.  These  methods  include  daily  marking of all  positions to market
value,  independent  verification of inventory pricing,  and position limits for
each trading activity.  Hedges in either the futures or cash markets may be used
to reduce the risk  associated with some trading  programs.  The Risk Management
Department  monitors trading activity daily and reports to senior management and
the Risk Oversight and Audit  Committee of the BOK Financial  Board of Directors
any exceptions to trading position limits and risk management policy exceptions.

Management  uses a Value at Risk ("VAR")  methodology to measure the market risk
inherent in its trading  activities.  VAR is  calculated  based upon  historical
simulations  over the past five years  using a variance /  covariance  matrix of
interest rate changes.  It represents an amount of market loss that is likely to
be exceeded only one out of every 100 two-week  periods.  Trading  positions are
managed within guidelines approved by the Board of Directors. These

 26

guidelines  limit the VAR to $1.6  million.  At June 30,  2005,  the VAR was $65
thousand. The greatest value at risk during the quarter was $736 thousand.

Controls and Procedures

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

Forward-Looking Statements

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

Statement of Position  03-3,  "Accounting  for Certain Loans or Debt  Securities
Acquired in a Transfer"  ("SOP  03-3") was issued by the  American  Institute of
Certified Public Accountants and is effective for loans acquired in fiscal years
beginning after December 15, 2004. SOP 03-3 addresses accounting for differences
between  contractual cash flows and expected cash flows from loans or securities
acquired in a transfer if those differences are attributable,  at least in part,
to credit  quality.  The Company has recorded its acquisition of Valley Commerce
in accordance with SOP 03-3 and other applicable  accounting  standards.  We are
continuing to review industry trends and regulatory  guidance in the application
of SOP 03-3,  but do not expect any material  adjustment to the reserve for loan
losses.

(1)      The Company had a stock repurchase plan that was initially authorized
         by the Company's board of directors on February 24, 1998 and amended on
         May 25, 1999. Under the terms of that plan, the Company could
         repurchase up to 800,000 shares of its common stock. As of March 31,
         2005, the Company had repurchased 638,642 shares under that plan. On
         April 26, 2005, the Company's board of directors terminated this
         authorization and replaced it with a new stock repurchase plan
         authorizing the Company to repurchase up to two million shares of the
         Company's common stock. As of June 30, 2005, the Company had
         repurchased 30,000 shares under the new plan.

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