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

Performance Summary

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

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

As disclosed in the previous  quarter's Form 10-Q, the Company  recognized $87.0
million of pre-tax  charges for loan and energy  derivative  credit  exposure to
SemGroup LP in the second quarter of 2008.  These charges reduced net income for
the second quarter of 2008 by  approximately  $57.0 million or $0.84 per diluted
share.  A $19.4  million  increase  in the fair  value of  derivative  contracts
related to SemGroup, partially offset by a $12.7 million write off of derivative
contracts  with Lehman  Brothers  increased  net income for the third quarter of
2008 by $4.5 million or $0.07 per diluted share.

Highlights of the third quarter of 2008 included:

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

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

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

 3

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

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

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


Results of Operations

Net Interest Revenue and Net Interest Margin

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

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

Funds  generated by growth in deposits and  borrowings  were also used to fund a
$437 million increase in average margin assets.  Margin assets are placed by the
Company to secure its obligations  under various  derivative  contracts.  Margin
assets are generally  reported as reductions of the derivative  liabilities they
secure on the Company's consolidated balance sheet.

Net  interest  margin  was 3.48% for the third  quarter  of 2008,  3.44% for the
second  quarter of 2008 and 3.27% for the third  quarter of 2007.  Growth in net
interest  margin  compared with the third quarter of 2007 was due primarily to a
widening of the spread  between LIBOR and the federal  funds rate.  LIBOR is the
basis for interest  earned on many of our loans.  The federal  funds rate is the
basis for interest paid on many of our interest-bearing liabilities.

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

The cost of  interest-bearing  liabilities  was 2.41% for the third  quarter  of
2008, down 198 basis points from the third quarter of 2007. The cost of interest
bearing  deposits  decreased  171  basis  points  to 2.39% and the cost of funds
purchased and other borrowings decreased 288 basis points to 2.16%.  Competition
for deposits in all our markets  limited our ability to move deposit  rates down
as interest rates declined.  The benefit to the net interest margin from earning
assets funded by  non-interest  bearing  liabilities  was 34 basis points in the
third quarter of 2008 compared with 67 basis points in the third quarter of 2007
and 30 basis points in the preceding quarter.

Management  regularly  models the  effects of changes in  interest  rates on net
interest  revenue.  Based on this  modeling,  we expect net interest  revenue to
decrease slightly over a one-year forward looking period. However, other factors
such as loan spread compression,  deposit product mix, the overall balance sheet
composition and the previously noted changes in the spread between LIBOR and the
federal funds rate may affect this general expectation.

Our overall  objective is to manage the Company's balance sheet to be relatively
neutral to changes in interest rates. Approximately two-thirds of our commercial
and commercial  real estate loan  portfolios  are either  variable rate or fixed
rate that will  re-price  within one year.  These loans are funded  primarily by
deposit  accounts that are either  non-interest  bearing,  or that re-price more
slowly  than the  loans.  The  result is a  balance  sheet  that  would be asset
sensitive,  which  means  that  assets  generally  re-price  more  quickly  than
liabilities. Among the strategies that we use to achieve a

 4

relatively  rate-neutral  position,  we  purchase  fixed-rate,   mortgage-backed
securities  to offset the  short-term  nature of the  majority of the  Company's
funding sources.  The  liability-sensitive  nature of this strategy  provides an
offset to the asset-sensitive characteristics of our loan portfolio. We also use
derivative  instruments  to manage our interest  rate risk.  Interest rate swaps
with a combined  notional amount of $685 million convert fixed rate  liabilities
to floating rate based on LIBOR. The purpose of these derivatives is to position
our balance sheet to be relatively neutral to changes in interest rates.

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

Other Operating Revenue

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

Diversified sources of fees and commission revenue are a significant part of our
business  strategy  and  generally  represent  40% to 45% of our total  revenue,
excluding  gains and  losses on asset  sales,  securities  and  derivatives.  We
believe  that a variety of fee revenue  sources  provide an offset to changes in
interest  rates,  values in the equity  markets,  commodity  prices and consumer
spending, all of which can be volatile.

Fees and commissions revenue

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

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

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

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

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

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

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

Margin asset fees  totaled  $1.9  million in the third  quarter of 2008 and $1.1
million in the third  quarter  of 2007.  Margin  assets  which are placed by the
Company to secure its obligations under customer  derivatives  programs averaged
$532 million for the third  quarter of 2008,  compared  with $95 million for the
third quarter of 2007. The increase in revenue earned on margin assets is offset
by a  decrease  in net  interest  revenue  due to the  costs to fund the  margin
assets.

BOK Financial  recognized  net gains of $2.1 million on securities for the third
quarter of 2008,  net gains on  securities of $4.7 million for the third quarter
of 2007 and net losses on securities  of $5.2 million for the second  quarter of
2008. Mortgage hedge securities held as an economic hedge of the changes in fair
value of mortgage  servicing  rights are carried at fair value.  Changes in fair
value of these securities are recognized in earnings as they occur.

Net gains on derivatives  totaled $4.4 million for the third quarter of 2008 and
$865 thousand for the third quarter of 2007.  Net gains or losses on derivatives
consist of fair value  adjustments of all  derivatives  used to manage  interest
rate risk and the related hedged  liabilities  when adjustments are permitted by
generally  accepted  accounting  principles.  Derivative  instruments  generally
consist of interest  rate swaps where the Company pays a variable  rate based on
LIBOR  and  receives  a fixed  rate.  The fair  value of these  swaps  generally
decreases as interest rates rise and increase in value as interest rates fall.

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

Other Operating Expense

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

Personnel expense

Personnel  expense totaled $87.5 million for the third quarter of 2008 and $85.8
million  for the third  quarter  of 2007,  including  personnel  expense of $2.5
million for net workforce reduction costs. Regular compensation,  which consists
of salaries and wages,  overtime pay and temporary personnel costs totaled $55.4
million,  up $1.8 million or 3% over the third quarter of 2007.  The increase in
regular compensation expense was due primarily to an increase in average regular
compensation  per full time equivalent  employee.  Average  staffing levels were
down 4% over the third quarter of last year.

Incentive  compensation  increased $2.3 million or 13% to $20.2 million compared
to the third  quarter of 2007.  Expense for  cash-based  incentive  compensation
plans  increased $4.6 million or 29%. These plans are either intended to provide
current rewards to employees who generate  long-term  business  opportunities to
the Company based on growth in loans, deposits, customer relationships and other
measurable  metrics or intended to  compensate  employees  with  commissions  on
completed  transactions.  The increase in cash-based incentive compensation over
the third quarter of 2007 included a

 8

$2.8 million increase in commissions related to brokerage and trading revenue.

The Company also provides stock-based incentive compensation plans.  Stock-based
compensation  plans  include  both  equity and  liability  awards.  Compensation
expense  related to liability  awards  decreased $2.7 million  compared with the
second quarter of 2008. This decrease  reflected  changes in the market value of
BOK  Financial  common  stock and other  investments.  The  market  value of BOK
Financial  common stock  decreased  $5.04 per share in the third quarter of 2008
and decreased $2.01 per share in the third quarter of 2007. Compensation expense
for equity awards increased $371 thousand or 30% compared with the third quarter
of 2007.  Expense for equity awards is based on the grant-date fair value of the
awards and is unaffected by subsequent changes in fair value.

Employee  benefit expense totaled $11.9 million,  a $120 thousand or 1% increase
over the third quarter of 2007.  Medical insurance costs were down $353 thousand
or 8%. The Company self-insures a portion of its employee health care coverage.

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

Data processing and communications expense

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

Other operating expenses

Occupancy and equipment  expenses totaled $15.6 million for the third quarter of
2008, up $818 thousand or 6% over 2007. Growth in occupancy expense was due to 3
new branch locations added in the past year.  Insurance  expense  increased $1.7
million  compared  to the  third  quarter  of 2007  due to an  increase  in FDIC
insurance   premiums.   A  one-time   credit  granted  to  eligible   depository
institutions  by the  Federal  Deposit  Insurance  Reform  Act of 2005 to offset
deposit insurance  premiums was largely used in 2007. The Company expects higher
deposit insurance expense as  recently-announced  increases in deposit insurance
premiums and other Treasury Department initiatives become effective.

Mortgage  banking costs included a $1.4 million increase in provision for losses
on residential  mortgage loans sold with recourse.  The Company's  obligation to
repurchase these loans is more-fully  discussed in the Loan Commitments  section
of this report.

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

Income Taxes

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

BOK  Financial  operates  in numerous  jurisdictions,  which  requires  judgment
regarding the allocation of income,  expense and earnings under various laws and
regulations of each of these taxing  jurisdictions.  Each jurisdiction may audit
our tax  returns  and  may  take  different  positions  with  respect  to  these
allocations.  The reserve for uncertain tax  positions was  approximately  $11.7
million at September 30, 2008.


Lines of Business

BOK Financial  operates five  principal  lines of business:  Oklahoma  corporate
banking,  Oklahoma consumer banking,  mortgage banking,  wealth management,  and
regional  banking.  Mortgage  banking  activities  include loan  origination and
servicing across all markets served by the Company.  Wealth management  provides
brokerage  and  trading,  private  financial  services and  investment  advisory
services in all  markets.  It also  provides  fiduciary  services in all markets
except  Colorado.  Fiduciary  services  in  Colorado  are  included  in regional
banking.  Regional banking consists  primarily of corporate and consumer banking
activities in the respective local markets.

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

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

The value of funds  provided  by the  operating  lines of  business to the funds
management unit is based on applicable

 10

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

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

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

Oklahoma Corporate Banking

The Oklahoma  Corporate  Banking Division  provides loan and lease financing and
treasury and cash  management  services to  businesses  throughout  Oklahoma and
certain  relationships in surrounding states. In addition to serving the banking
needs of small businesses, middle market and larger customers, this Division has
specialized groups that serve customers in the energy,  agriculture,  healthcare
and banking/finance industries, and includes the TransFund network. The Oklahoma
Corporate Banking Division contributed $34.1 million to net income for the third
quarter  of 2008,  up from $21.7  million  for the third  quarter of 2007.  This
Division recognized a $53.0 million after-tax loss in the second quarter of 2008
on loans and derivative  contracts  with  SemGroup.  During the third quarter of
2008,  the fair  value of  certain  derivative  contracts  related  to  SemGroup
increased  by $19.4  million due to falling  energy  prices.  The change in fair
value of these  contracts  increased net income after taxes by $11.9 million for
the third quarter of 2008. The increase in fair value of derivative contracts is
included  in Other  Operating  Revenue.  Excluding  changes in the fair value of
these contracts,  the Oklahoma  Corporate Banking  Division's net income for the
third quarter of 2008 was $22.3 million, up $585 thousand over the third quarter
of 2007.

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

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

Oklahoma Consumer Banking

The Oklahoma Consumer Banking Division provides a full line of deposit, loan and

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

The Oklahoma  Consumer Banking  Division  contributed net income of $7.1 million
for the third  quarter of 2008,  compared to net income of $9.3  million for the
third quarter of 2007. Net interest  revenue  decreased $2.8 million or 15% over
2007 due  primarily  to a decrease  in the  internal  transfer  pricing  credit.
Average  loans  attributed  to the Oklahoma  Consumer  Banking  Division in 2008
increased $17 million or 6% compared with 2007. Average deposits provided by the
Oklahoma  Consumer  Banking  Division  grew $109 million or 4% to $3.0  billion.
Average demand deposits were up $44 million or 13% over 2007.  Interest  bearing
deposits  increased $65 million or 3%,  including a $213 million or 21% increase
in interest bearing  transaction  accounts and a $152 million or 10% decrease in
time deposits.

Other  operating  revenue was up $1.0 million or 5% over 2007 largely from check
card revenue and overdraft fees. Operating expenses increased $2.0 million or 9%
over 2007,  including a $514 thousand or 6% increase in personnel  expense and a
$1.5 million or 14% increase in non-personnel  expense.  Net loans  charged-off,
which consist primarily of overdrawn deposit accounts, totaled $835 thousand for
the third quarter of 2008 and $1.0 million for the third quarter of 2007.

Mortgage Banking

BOK Financial  engages in mortgage banking  activities  through the BOk Mortgage
Division  of  Bank  of  Oklahoma.  These  activities  include  the  origination,
marketing and servicing of conventional and government-sponsored mortgage loans.
BOk Mortgage  incurred a net loss of $2.4  million in the third  quarter of 2008
compared to net income of $504 thousand in the third quarter of 2007. Changes in
the fair value of mortgage  servicing rights,  net of hedging activity,  reduced
net income $2.7 million in 2008 and  increased net income $127 thousand in 2007.
In addition,  an increase in the provision for off-balance  sheet credit risk on
mortgage  loans sold with recourse  reduced net income $1.3 million in the third
quarter of 2008 and $500 thousand for the third quarter of 2007.

Mortgage banking activities consisted primarily of two sectors,  loan production
and loan servicing.  The loan  production  sector  generally  performs best when
mortgage  rates  are  relatively  low and loan  origination  volumes  are  high.
Conversely,  the loan  servicing  sector  generally  performs best when mortgage
rates are relatively high and prepayments are low. The Mortgage Banking Division
also holds a permanent  portfolio of $468 million of residential  mortgage loans
which generated net income of $513 thousand in the third quarter of 2008.

Loan Production Sector

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

Loan Servicing Sector

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

Servicing revenue,  including revenue on loans serviced for affiliates,  totaled
$5.0  million in third  quarter  of 2008  compared  to $4.7  million in the same
period of 2007. The average  outstanding  balance of loans  serviced,  including

BOK Financial  designated a portion of its  securities  portfolio as an economic
hedge  against the risk of changes in the fair value of its  mortgage  servicing
rights.  These securities,  which are identified as mortgage trading  securities
are carried at fair value.  Changes in fair value are  recognized in earnings as
they occur.  Additionally,  mortgage-related  derivative  contracts  may also be
designated  as an  economic  hedge  of the  risk of loss on  mortgage  servicing
rights.  Because  the fair  values of these  instruments  are  expected  to vary
inversely  to the fair  value of the  servicing  rights,  they are  expected  to
partially  offset risk. No special hedge  accounting  treatment is applicable to
either the mortgage servicing rights or the financial instruments  designated as
an economic hedge.

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

At September 30, 2008,  financial  instruments with a fair value of $198 million
were held for the economic hedge program.  The interest rate  sensitivity of the
mortgage servicing rights and securities held as a hedge is modeled over a range
of +/- 50 basis  points.  At  September  30, 2008,  the pre-tax  results of this
modeling on reported earnings were:


Table 9 - Interest Rate Sensitivity - Mortgage Servicing
(Dollars in Thousands)
                                          50 bp increase   50 bp decrease
Anticipated change in:
Fair value of mortgage servicing rights   $    4,498      $   (4,927)
Fair value of hedging instruments             (4,649)          3,697
                                        ----------------- ----------------
Net                                       $     (151)     $   (1,230)
                                        ----------------- ----------------


Table 9 shows the non-linear  effect of changes in mortgage  commitment rates on
the value of mortgage  servicing  rights.  A 50 basis point increase in rates is
expected to increase the fair value of our servicing rights $4.5 million while a
50 basis point decrease is expected to reduce the fair value $4.9 million.  This
considers that there is an upper limit to appreciation in the value of servicing
rights as rates  rise due to the  contractual  repayment  terms of the loans and
other  factors.  There is much  less of a limit of the  speed at which  mortgage
loans may prepay in a declining rate environment.

Modeling  changes in the value of  mortgage  servicing  rights due to changes in
interest rates assumes stable  relationships  between mortgage  commitment rates
and discount rates used to determine the present value of future cash flows.  It
also assumes a stable  relationship  between the assumed loan prepayment  speeds
and actual  prepayments of our loans.  Changes in market conditions can increase
or decrease the discount  spread over  benchmark  rates expected by investors in
mortgage servicing rights and actual prepayments may increase or decrease due to
factors other than changes in interest rates. These factors and others may cause
changes  in the  value of our  mortgage  servicing  rights  to  differ  from our
expectations.

institutional  securities  sales.  Net income for the third  quarter of 2007 was
decreased  $1.4  million for the  after-tax  cost of the  settlement  of certain
matters  with  the  American  Performance  Funds.  Net  income  for  the  Wealth

assets  with  aggregate  market  values  of $30.4  billion  and  $31.8  billion,
respectively,  under various fiduciary arrangements.  The change in trust assets
reflected lower market value of assets managed  partially offset by new business
generated  during the year. We have sole or joint  discretionary  authority over
$11.5 billion of trust assets at September 30, 2008 compared to $11.8 billion of
trust assets at September  30, 2007.  The fair value of  non-managed  assets was

Division's  net income in the third  quarter of 2008 compared to $2.5 million in
2007. Trading fees and commissions  revenue increased $5.8 million due primarily
to a $4.1 million increase in revenue from  institutional  securities and a $1.7
million  increase in customer  derivative  revenue.  Operating  expenses,  which
consist  primarily  of  compensation  expense  increased  $2.4  million  or 18%.
Incentive  compensation  expense which is directly related to revenue growth was
up $2.6 million.

Financial Condition

Securities

Investment securities,  which consist primarily of Oklahoma municipal bonds, are
carried at cost and  adjusted  for  amortization  of  premiums or  accretion  of
discounts.  At September 30, 2008,  investment  securities  were carried at $244
million  and had a fair value of $240  million.  Management  has the ability and
intent to hold these securities until they mature.

Available for sale securities,  which may be sold prior to maturity, are carried
at fair value.  Unrealized gains or losses, less deferred taxes, are recorded as
accumulated other  comprehensive  income in shareholders'  equity. The amortized
cost of available  for sale  securities  totaled  $6.4 billion at September  30,
2008, up $420 million  compared with June 30, 2008.  Mortgage-backed  securities
represented  97% of total  available for sale  securities.  The Company holds no
debt securities of corporate issuers.

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


A primary risk of holding mortgage-backed securities comes from extension during
periods  of rising  interest  rates or  prepayment  during  periods  of  falling
interest  rates. We evaluate this risk through  extensive  modeling of risk both
before  making  an  investment  and  throughout  the life of the  security.  The
expected duration of the mortgage-backed  securities portfolio was approximately
2.8 years at September 30, 2008. Management estimates that the expected duration
would extend to  approximately  3.3 years  assuming an immediate 300 basis point
upward rate shock.

Mortgage-backed  securities also have credit risk from delinquency or default of
the underlying loans. The Company mitigates this risk by primarily  investing in
securities  issued by FNMA and FHLMC.  Principal  and  interest  payments on the
underlying loans are fully guaranteed. At September 30, 2008, approximately $4.8
billion  of  the  Company's  mortgage-backed  securities  were  issued  by  U.S.
government agencies.

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

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

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

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

Certain mortgage-backed  securities,  identified as mortgage trading securities,
have been  designated as economic  hedges of mortgage  servicing  rights.  These
securities  are carried at fair value with changes in fair value  recognized  in
current period income.  These  securities are held with the intent that gains or
losses will offset changes in the fair value of mortgage  servicing rights.  The
Company  also  maintains  a  separate  trading   portfolio.   Trading  portfolio
securities,  which

 20

are also carried at fair value with changes in fair value  recognized in current
period income,  are acquired and held with the intent to sell at a profit to the
Company.

Bank-Owned Life Insurance

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

Loans

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

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

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

 21


and gas  producers,  up from $1.6 billion at June 30, 2008. The amount of credit
available to these customers  generally  depends on a percentage of the value of
their proven energy  reserves based on anticipated  prices.  The energy category
also included loans to borrowers  involved in the transportation and sale of oil
and gas and to borrowers that manufacture equipment or provide other services to
the energy  industry.  The energy  category of our loan portfolio is distributed
$1.1 billion in Oklahoma, $615 million in Texas and $392 million in Colorado.

The services  sector of the loan portfolio  totaled $2.0 billion or 16% of total
loans  and  consists  of a large  number of loans to a  variety  of  businesses,
including communications, gaming and transportation services. Approximately $1.3
billion of the services category is made up of loans with individual balances of
less than $10 million.  Approximately $718 million of the outstanding balance of
services loans is attributed to Texas, $644 million to Oklahoma, $244 million to
New Mexico, $141 million to Arizona and $108 million to Colorado.

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

BOK Financial participates in shared national credits when appropriate to obtain
or maintain business relationships with local customers. Shared national credits
are defined by banking  regulators  as credits of more than $20 million and with
three or more non-affiliated  banks as participants.  At September 30, 2008, the
outstanding principal balance of these loans totaled $2.1 billion. Substantially
all of these  loans  are to  borrowers  with  local  market  relationships.  BOK
Financial serves as the agent lender in approximately 23% of its shared national
credits,  based on dollars  committed.  The Company's lending policies generally
avoid loans in which we do not have the opportunity to maintain or achieve other
business relationships with the customer.

Commercial  real estate loans totaled $2.7 billion or 21% of the loan  portfolio
at September 30, 2008.  Over the past five years,  the  percentage of commercial
real  estate  loans to our total  loan  portfolio  ranged  from 20% to 23%.  The
outstanding  balance of commercial real estate loans decreased $114 million from
the previous quarter end.  Construction and land development loans decreased $53
million to $969 million.  Loans secured by industrial  facilities  decreased $29
million and other  commercial  real estate loans  decreased  $95 million.  Loans
secured  by  office  buildings  increased  $48  million  and  loans  secured  by
multifamily residential properties increased $17 million.

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

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

At  September  30,  2008,  consumer  loans  included  $721  million of  indirect
automobile loans.  Approximately $454 million of these loans were purchased from
dealers in Oklahoma and $176 million  were  purchased  from dealers in Arkansas.
The  remaining  $91  million  were  purchased  from  dealers in Texas.  Indirect
automobile loans decreased $14 million since June 30, 2008.  Approximately 6% of
the outstanding balance at September 30, 2008 is considered near-prime, which is
defined  as  loans  to  borrowers  that  had  poor  credit  in the past but have
re-established  credit  over a period of time.  We  generally  do not  originate
sub-prime indirect automobile loans.

Loan Commitments

BOK Financial enters into certain  off-balance sheet  arrangements in the normal
course of business.  These arrangements  included loan commitments which totaled
$5.3  billion  and  standby  letters of credit  which  totaled  $601  million at
September 30, 2008. Loan commitments may be unconditional obligations to provide
financing or conditional  obligations  that depend on the  borrower's  financial
condition,  collateral  value or other  factors.  Standby  letters of credit are
unconditional  commitments  to guarantee  the  performance  of our customer to a
third party. Since some of these commitments are expected to expire before being
drawn upon, the total commitment amounts do not necessarily

 23

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

The Company also has off-balance  sheet  commitments  for  residential  mortgage
loans sold with full or partial  recourse.  These  loans  consist of first lien,
fixed  rate  residential  mortgage  loans  originated  under  various  community
development  programs  and sold to U.S.  government  agencies.  These loans were
underwritten   to   standards   approved  by  the   agencies,   including   full
documentation. However, these loans have a higher risk of delinquency and losses
given default than traditional  residential  mortgage loans. A separate recourse
reserve is maintained as part of other liabilities.

At September 30, 2008,  the principal  balance of loans sold subject to recourse
obligations  totaled  $388  million.  Substantially  all of these  loans  are to
borrowers  in our  primary  markets  including  $274  million  to  borrowers  in
Oklahoma,  $44 million to borrowers in Arkansas, $22 million to borrowers in New
Mexico,  $18  million to  borrowers  in the Kansas  City area and $16 million to
borrowers in Texas. The separate reserve for these off-balance sheet commitments
was $8.6 million at September  30, 2008.  Approximately  2.17% of the loans sold
with recourse with an outstanding  principal balance of $8.2 million were either
delinquent more than 90 days, in bankruptcy or in foreclosure. The provision for
credit losses on loans sold with recourse, which is included in mortgage banking
costs,  was $2.2  million  for the third  quarter of 2008.  Net  losses  charged
against the reserve totaled $1.2 million for the third quarter of 2008.


Derivatives with Credit Risk

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

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

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

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

Derivative  contracts are carried at fair value.  At September 30, 2008, the net
fair values of  derivative  contracts  reported as assets  under these  programs
totaled  $572  million,  down from  $1.4  billion  at June 30,  2008 due to cash
settlements  and falling energy prices.  At September 30,  derivative  contracts
carried as assets  included  energy  contracts with fair values of $415 million,
interest rate  contracts with fair values of $93 million,  agricultural  product
contracts  with fair values of $4 million and foreign  exchange  contracts  with
fair  values  of $53  million.  The  aggregate  net fair  values  of  derivative
contracts  held under  these  programs  reported  as  liabilities  totaled  $374
million. As of January 1, 2008, the Company adopted FASB Staff Position FIN 39-1
which permits offsetting of cash collateral against the fair value of derivative
instruments   executed  with  the  same  counterparty  under  a  master  netting
agreement.  The total amount of derivative liabilities at September 30, 2008 was
reduced by $217 million of cash  collateral.  A table  showing the fair value of
derivative assets and liabilities,  net of cash margin, is presented in Footnote
3 to the  Consolidated  Financial  Statements  (Unaudited),  which  follows this
report.

In  addition  to  cash  margin,  the  Company  accepts  liens  against  physical
commodities as collateral for derivative contracts.  The fair value of contracts
backed by energy production totaled  approximately  $221 million.  Approximately
$67 million of the fair value of derivative  contracts are with customers  which
store or transport energy products.  Credit risk of these contracts is backed by
physical product and other collateral, including cash margin held by the Company
and  letters  of credit  issued by  third-party  banks  for the  benefit  of the
Company.

The  largest  amount  due  from  a  single  counterparty,  a  subsidiary  of  an
international  energy company, at September 30, 2008 was $67 million. The amount
due from this  counterparty  decreased  to $35 million  through  receipt of cash
margin the next day.

Summary of Loan Loss Experience

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

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

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

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

The  Company  considers  the credit  risk from loan  commitments  and letters of
credit in its  evaluation  of the  adequacy of the reserve  for loan  losses.  A
separate  reserve for  off-balance  sheet  credit risk is  maintained.  Table 20
presents  the trend of reserves  for  off-balance  sheet  credit  losses and the
relationship between the reserve and loan commitments.  The relationship between
the combined  reserve for credit losses and outstanding  loans is also presented
for  comparison  with peer banks and others who have not adopted  the  preferred
presentation.  The provision for credit losses  included the combined  charge to
expense for both the  reserve  for loan  losses and the reserve for  off-balance
sheet credit losses. All losses incurred from lending activities will ultimately
be reflected in charge-offs  against the reserve for loan losses following funds
advanced against outstanding  commitments and after the exhaustion of collection
efforts.

Specific  impairment  reserves are  determined  through  evaluation of estimated
future  cash  flows and  collateral  value.  At  September  30,  2008,  specific
impairment  reserves  totaled  $4.0  million  on  total  impaired  loans of $201
million. Specific impairment reserves were $11.0 million on total impaired loans
of $139 million at June 30, 2008.  Approximately  $7.5 million of loans impaired
at June 30, 2008 were charged off in the third quarter.

Nonspecific  reserves are  maintained  for risks beyond  factors  specific to an
individual  loan or those  identified  through  migration  analysis.  A range of
potential  losses is determined  for each risk factor  identified.  The range of
nonspecific  reserves for general  economic factors includes their effect on our
commercial,  commercial  real estate,  residential  mortgage  and consumer  loan
portfolios.  Nonspecific  reserves  attributed  to general  economic  conditions
increased  in the third  quarter of 2008.  Weakness in the  economy  became more
apparent due to disruption in the credit markets,  lower consumer confidence and
continued weakness in residential real estate markets.

The provision  for credit losses  totaled $52.7 million for the third quarter of
2008,  $59.3  million  for the second  quarter of 2008 and $7.2  million for the
third  quarter of 2007.  The second  quarter of 2008  provision  included  $26.3
million  directly  related  to the  Company's  loans  and  loan  commitments  to
SemGroup.  Factors considered in determining the provision for credit losses for
the third quarter of 2008 included trends in net losses and nonperforming loans,
the   application   of  statistical   migration   factors  to  loan  growth  and
concentrations in commercial real estate and residential  homebuilder  loans. In
addition, the outstanding balances of potential problem loans increased.

Nonperforming Assets

Non-performing  assets  totaled $252 million or 1.98% of  outstanding  loans and
repossessed  assets at September  30, 2008,  up $71 million since June 30, 2008.
The  increase in  non-performing  assets  included an expected  $36 million from

million  due  from   SemGroup.   This  amount   represents   one-third   of  our
pre-bankruptcy   amounts  due  from  SemGroup.  In  addition,   $27  million  of
non-accruing  commercial loans are in the services sector of the loan portfolio.
The  distribution  of  non-accruing  commercial  loans among our various markets
included  $75 million in  Oklahoma,  $12 million in Colorado  and $10 million in
Texas.  Non-accruing  commercial loans included $21.5 million of shared national
credits  at  September  30,  2008.  This  represents  1.03%  of the  outstanding
principal  balance  of  shared  national  credits.  The  total  of  non-accruing
commercial  loans was  unchanged  during the third  quarter  of 2008,  excluding
SemGroup funded letters of credit and derivative contracts.

Non-accruing  commercial  real  estate  loans  totaled  $78  million or 2.88% of
outstanding  commercial  real estate loans at September  30, 2008.  Non-accruing
commercial  real estate loans included $54 million of land and  residential  lot
and construction loans, $13 million of loans secured by retail properties and $3
million of loans secured by office  buildings.  The distribution of non-accruing
commercial real estate loans among our various  markets  included $51 million in

outstanding  residential mortgage loans at September 30, 2008. Non-accruing home
equity loans totaled $674 thousand or 0.14% of outstanding home equity loans and
non-accruing  permanent  residential mortgage loans totaled $26 million or 2.21%
of  outstanding  permanent  residential  mortgage  loans.  The  distribution  of
non-accruing  residential  mortgage loans among our various markets included $10
million in Texas, $9 million in Oklahoma and $3 million in Arizona. Non-accruing
residential mortgage loans increased $9 million during the third quarter of 2008
compared to the previous quarter.

Real estate and other  repossessed  assets  totaled $28 million at September 30,
2008,  up from $21 million at June 30, 2008.  Real estate and other  repossessed
assets included $17 million of 1-4 family residential properties and residential
land  development  properties,  $5 million of developed  commercial  real estate
properties,  $4 million of undeveloped land and $2 million of automobiles.  Real
estate owned and other  repossessed  assets are  primarily  located in Oklahoma,

Our loan review process also identified  loans that possess more than the normal
amount of risk due to deterioration  in the financial  condition of the borrower
or the value of the  collateral.  Because the borrowers are still  performing in
accordance  with  the  original  terms of the  loan  agreements,  and no loss of
principal  or  interest  is  anticipated,  these  loans  were  not  included  in
Nonperforming Assets. Known information does, however,  cause management concern
as to the

 28

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


Deposits

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

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

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

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

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

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

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

Borrowings and Capital

On July 21, 2008, the Company entered into a $188 million,  unsecured  revolving
credit agreement with George B. Kaiser, its Chairman and principal  shareholder.
Interest on the  outstanding  balance is based on one-month LIBOR plus 125 basis
points and is payable quarterly.  Additional  interest in the form of a facility
fee is paid  quarterly  on the  unused  portion  of the  commitment  at 25 basis
points.  This agreement has no  restrictive  covenants,  which provides  greater
flexibility to fund the needs of BOK Financial and its  subsidiaries.  The lack
of  restrictive  covenants in this  agreement  also provides the Company time to
maximize the  recovery on  nonperforming  assets.  At  September  30, 2008,  the
outstanding balance under this credit agreement was $50 million.

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

The primary source of liquidity for BOK Financial is dividends  from  subsidiary
banks,  which are limited by various  banking  regulations  to net  profits,  as
defined,  for the  preceding  two years.  Dividends  are further  restricted  by
minimum capital  requirements.  Based on the most restrictive  limitations,  the
subsidiary  banks  could  declare  up  to  $128  million  of  dividends  without
regulatory  approval.  Management  has  developed and the Board of Directors has
approved an internal capital policy that is more restrictive than the regulatory
capital  standards.  The subsidiary banks could declare  dividends of up to $109
million under this policy.

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

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

On April 26, 2005, the Board of Directors authorized a share repurchase program,
which  replaced a  previously  authorized  program.  The  maximum of two million
common  shares  may be  repurchased.  The  specific  timing and amount of shares
repurchased will vary based on market conditions, securities law limitations and
other  factors.  Repurchases  may be made over time in open market or  privately
negotiated transactions. The repurchase program may be suspended or discontinued
at any time without prior notice.  Since this program began, 784,073 shares have
been  repurchased  by the Company  for $38.7  million.  The Company  repurchased
75,000 shares for $3.3 million in the third quarter of 2008.

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

For a banking institution to qualify as well capitalized,  its Tier 1, Total and
Leverage  capital ratios must be at least 6%, 10% and 5%,  respectively.  All of
the Company's banking subsidiaries  exceeded the regulatory  definitions of well
capitalized.  The capital ratios for BOK Financial on a  consolidated  basis are
presented in Table 23.

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

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

(federal funds purchased) and newly issued unsecured debt.

Off-Balance Sheet Arrangements

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

Market Risk

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

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

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

Interest Rate Risk - Other than Trading

As  previously  noted  in the Net  Interest  Revenue  section  of  this  report,
management has implemented  strategies to manage the Company's  balance sheet to
be relatively  neutral to changes in interest  rates over a twelve month period.
The effectiveness of these strategies in managing the overall interest rate risk
is evaluated through the use of an asset/liability model. BOK Financial performs
a sensitivity  analysis to identify more dynamic  interest rate risk  exposures,
including  embedded option positions,  on net interest  revenue,  net income and
economic value of equity.  A simulation  model is used to estimate the effect of
changes  in  interest  rates over the next  twelve and 24 months  based on eight
interest  rate  scenarios.  Two specified  interest  rate  scenarios are used to
evaluate  interest  rate risk against  policy  guidelines.  The first  assumes a
sustained  parallel 200 basis point  increase and the second assumes a sustained
parallel 100 basis point  decrease in interest  rates.  Management  historically
evaluated  interest rate sensitivity for a sustained 200 basis point decrease in
interest rates.  However,  the results of a 200 basis point decrease in interest
rates in the current low-rate  environment are not meaningful.  The Company also
performs a sensitivity analysis based on a "most likely" interest rate scenario,
which includes  non-parallel  shifts in interest rates. An independent source is
used to determine the most likely interest rate scenario.

 32

The Company's  primary interest rate exposures  included the Federal Funds rate,
which affects short-term borrowings, and the prime lending rate and LIBOR, which
are the basis for much of the variable-rate loan pricing. Additionally, mortgage
rates directly affect the prepayment speeds for  mortgage-backed  securities and
mortgage servicing rights.  Derivative financial instruments and other financial
instruments   used  for  purposes  other  than  trading  are  included  in  this
simulation.  The model incorporates assumptions regarding the effects of changes
in interest rates and account balances on indeterminable maturity deposits based
on a combination  of historical  analysis and expected  behavior.  The impact of
planned  growth and new  business  activities  is factored  into the  simulation
model.  The  effects  of  changes  in  interest  rates on the value of  mortgage
servicing  rights are excluded from Table 24 due to the extreme  volatility over
such a large rate range.  The effects of interest  rate  changes on the value of
mortgage  servicing  rights and  securities  identified  as economic  hedges are
presented in the Lines of Business - Mortgage Banking section of this report.

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

Trading Activities

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

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

Management  uses a Value at Risk ("VAR")  methodology to measure the market risk
inherent in its trading  activities.  VAR is  calculated  based upon  historical
simulations  over the past five years  using a variance /  covariance  matrix of
interest rate changes.  It represents an amount of market loss that is likely to
be exceeded only one out of every 100 two-week  periods.  Trading  positions are
managed within guidelines  approved by the Board of Directors.  These guidelines
limit the VAR to $3.6 million.  At September 30, 2008, the VAR was $1.8 million.
The greatest  value at risk during the third  quarter of 2008 was $2.1  million.
The  value  at  risk  guideline  was  exceeded  with  appropriate  approvals  by
management  to take  advantage of wide yields  available  on certain  securities
during the quarter.

Controls and Procedures

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


Forward-Looking Statements

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

Notes to Consolidated Financial Statements (Unaudited)

(1) Accounting Policies

Basis of Presentation

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

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

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

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

The financial  information  should be read in conjunction  with BOK  Financial's
2007 Form 10-K filed with the Securities and Exchange Commission, which contains
audited  financial  statements.  Amounts  presented as of December 31, 2007 have
been derived from BOK Financial's 2007 Form 10-K.

Newly Adopted and Pending Accounting Policies

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

As of January 1, 2008, the Company adopted Financial  Accounting Standards Board
Staff Position FIN 39-1, which permits offsetting of cash collateral against the
fair value of derivative instruments executed with the same counterparty under a
master netting agreement.  The total amount of derivative assets and liabilities
at September 30, 2008 was reduced by $19 million and $217 million, respectively,
of cash collateral.

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

Statement  of  Financial  Accounting  Standards  No.  161,   "Disclosures  About
Derivative Instruments and Hedging Activities, an

 39

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

(1)  A  reconciliation  of the  beginning  and  ending  fair  value of  mortgage
     servicing  rights  and  disclosures  of  significant  assumptions  used  to
     determine fair value are presented in Note 4, Mortgage Banking Activities.

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

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

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

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

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

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

At June 30, 2008,  the fair value of  derivative  contracts  with SemGroup LP of
$36.6 million was largely based on significant  unobservable inputs. On July 22,
2008,  SemGroup and 24 related  entities  filed for bankruptcy  protection.  BOK
Financial assessed a range of values for the derivative  contracts with SemGroup
using  information  currently  available,  including  information  provided by a
nationally recognized financial advisor to SemGroup. During the third quarter of
2008, the fair value of these contracts decreased by $4.6 million.  The decrease
in fair value,  which was based largely on significant  unobservable  inputs and
changes in energy  prices during the quarter,  was  recognized as a reduction of
fees and  commissions  revenue.  All derivative  contracts with SemGroup  either
expired or were terminated  during the third quarter.  The fair value of amounts
due from SemGroup under these  contracts  totaled $32.0 million.  This amount is
included in outstanding commercial loans at September 30, 2008.

No significant  fair value  measurements  of  significant  assets or liabilities
measured on a  non-recurring  basis were made during the first three quarters of
2008.  Assets  measured on a  non-recurring  basis include  pension plan assets,
which are based on quoted prices in active  markets for  identical  instruments,
real  property  and other  assets  acquired  to satisfy  loans,  which are based
primarily on comparisons  of completed  sales of similar  assets,  and goodwill,
which is based on significant unobservable inputs.

Certain  certificates  of deposit  were  designated  as carried at fair value as
permitted by FAS 159. These certificates have been converted from fixed interest
rates to variable  interest  rates based on LIBOR with interest rate swaps.  The
fair value election for these liabilities  better represents the economic effect
of these  instruments on the Company.  At September 30, 2008, the fair value and

 (10)  Commitments and Contingent Liabilities

In September 2006, BISYS settled the SEC's two-year  investigation of BISYS Fund
Services Ohio, Inc. ("BISYS") marketing assistance  agreements with 27 different
families of mutual funds,  including a BISYS  marketing  arrangement  with AXIA,
which had been  terminated  effective  January 1, 2004.  In the SEC  settlement,
BISYS  consented  to an  order  in  which  the SEC  determined  that  BISYS  had
"willfully  aided and  abetted and  caused"  the 27  investment  advisors to (i)
violate  provisions  of the  Investment  Advisors  Act  of  1940  that  prohibit
fraudulent  conduct;  (ii) violate  provisions of the 1940 Act that prohibit the
making of any untrue  statement of a material fact in a  registration  statement
filed by the mutual fund with the SEC, and (iii) violate  provisions of the 1940
Act that require the disclosure and inclusion of all  distribution  arrangements
and expenses in the fund's 12b-1 fee plan ("the SEC BYSIS Order").  AXIA was one
of the 27 advisors and the AP Funds one of the 27 mutual fund  families to which
the SEC  referred in its BISYS  Order.  On October 10,  2006,  the  Examinations
Division of the  Securities  and Exchange  Commission  (the "SEC")  conducted an
examination of AXIA. The  examination  was concluded in July 2007 with no action
taken by the  Examinations  Division.  In August  2007,  AXIA settled all claims
relating to the BISYS marketing  arrangements with the AP Funds for $2.2 million
and the AP Funds regard the matter as fully  concluded.  The settlement with the
AP Funds is not binding on the SEC.

On April 7, 2008,  AXIA and its parent,  BOK,  received a Wells  notice from the
regional  office  of  the  SEC in Los  Angeles  indicating  that  the  staff  is
considering  recommending  that the SEC bring a civil injunctive  action against
AXIA and BOK for  violations  of Section  17(a) of the  Securities  Act of 1955,
Section 10(b) of the Securities Exchange Act of 1934, Sections 206(1) and (2) of
the  Investment  Advisors  Act of 1940,  and  Sections  12(b)  and  34(b) of the
Investment Company Act of 1940. BOK and AXIA have been cooperating fully with

 45

the SEC in connection  with these matters that arose prior to December 31, 2003.
BOK and AXIA are not bound by the SEC  BISYS  Order  and  disagree  with the SEC
position as it relates to BOK and AXIA. On May 27, 2008,  BOK and AXIA responded
to the Wells notice  denying the SEC  position.  On June 26, 2008,  BOK and AXIA
representatives  met with SEC Staff at which time the SEC Staff advised that the
Staff had not determined  whether to recommend any action to the Commission.  On
September  25,  2008,  The SEC Staff  requested,  and BOK and AXIA  agreed to, a
tolling  agreement  for any action the SEC might take until  January  15,  2009.
Nothing further has occurred as of the time of this filing.

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

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

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

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

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

(12) Financial Instruments with Off-Balance Sheet Risk

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

(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 September 30,
     2008, the Company had repurchased 784,073 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.
