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

Performance Summary

BOK Financial Corporation ("BOK Financial" or the "Company") reported net income
of $52.7  million,  or $0.78 per  diluted  share for the third  quarter of 2006,
compared with $50.8 million, or $0.76 per diluted share for the third quarter of
2005. The annualized  returns on average  assets and  shareholders'  equity were
1.24% and 12.90%,  respectively  for 2006,  compared  with  returns of 1.29% and
13.56%, respectively for 2005.

Highlights of the quarter included:

o    Average  outstanding  loans and  average  deposits  increased  14% and 13%,
     respectively over the third quarter of 2005.

o    Net  interest  revenue  grew $11.2  million or 10% over last  year's  third
     quarter, 9% annualized over the second quarter of 2006.

o    Net interest  margin was 3.38%,  up from 3.32% in the third quarter of last
     year and stable throughout 2006.

o    Fee income increased $2.7 million or 3% over the third quarter of 2005.

o    Fair value of mortgage  servicing  rights  declined  $4.2  million,  net of
     hedging gains during the third quarter.

o    Other  operating  expenses  increased $9.2 million or 8%,  including a $1.8
     million  non-cash  charge related to taxes on a $202 million  investment in
     bank-owned life insurance; personnel costs were up $8.1 million.

o    Income tax expense was reduced $2.2 million for the favorable resolution of
     certain tax issues.

o    Non-performing  loans,  annualized  net  charge-offs  continued  to be near
     historic lows.

Net interest  revenue grew $11.2 million or 10% over 2005.  Average  outstanding
loan balances  increased $1.2 billion or 14% and average deposits increased $1.3
billion or 13%. Fees and  commission  revenue  increased $2.7 million or 3% over
the third quarter of 2005. Total fee revenue, which recently had been growing at
a  low  double  digit  rate,  slowed  in  most  major  categories  of  fees  and
commissions.  Mortgage banking revenue decreased $2.6 million or 27% due largely
to lower production volumes.

Operating  expenses increased $9.2 million or 8% over the third quarter of 2005,
excluding changes in the value of mortgage servicing.  Personnel costs increased
$8.1 million due largely to a $5.0 million  increase in salaries and wages and a
$2.8 million increase in incentive compensation.

The fair value of mortgage  servicing  rights  decreased $7.9 million during the
third quarter of 2006 due to falling  interest rates and  increasing  prepayment
speeds.  At the  same  time,  falling  interest  rates  increased  the  value of
securities held as an economic hedge of mortgage  servicing  rights $3.7 million
for a net pre-tax loss of $4.2 million.

 3

Non-accruing  loans  totaled  $30  million  or  0.31%  of  outstanding  loans at
September 30, 2006 compared with $37 million or 0.42 % of  outstanding  loans at
September  30,  2005.  The  combined  allowance  for loan losses and reserve for
off-balance  sheet credit  losses  totaled $127 million or 1.28% of  outstanding
loans at September  30, 2006 and $127 million or 1.44% of  outstanding  loans at
September  30, 2005.  The  provision  for credit losses was $5.3 million for the
third quarter of 2006 and $4.0 million for the same period last year.

Net income for the first nine months of 2006  totaled  $162.4  million,  up $9.0
million or 6% over  2005.  Net  interest  revenue  grew $29.5  million or 9% due
primarily to a $1.2 billion increase in average loans. Loan growth was funded by
a $1.4 billion increase in average  deposits.  Net interest margin for the first
nine  months of 2006 and 2005 was  3.39% and  3.41%,  respectively.  Fee  income
increased $20.8 million or 8%. All categories of fee income  increased over 2005
except mortgage banking revenue which decreased $2.7 million or 12%. Transaction
card revenue increased $5.4 million or 10% due to volume growth while trust fees
rose $4.1 million or 9%.  Mortgage  banking  revenue  decreased due largely to a
reduction in loan production volume which resulted from rising mortgage interest
rates over the last nine  months.  Other  revenue  grew $9.2  million or 38% due
primarily to a $4.0 million increase in fees on margin assets. The fair value of
mortgage  servicing  rights,  net of losses on  securities  held as an economics
hedge,  increased  $2.1  million  for the first nine  months of 2006.  Operating
expenses  increased  $33.1  million or 10% due to a $27.9  million  increase  in
personnel costs.

The  Company  is  establishing  a new  regional  bank in  Kansas  City.  Initial
operations are expected to begin in the fourth quarter of 2006.

Results of Operations

Net Interest Revenue

Tax-equivalent  net interest  revenue  increased to $125.8 million for the third
quarter of 2006 from $114.1 million for 2005, due primarily to a $1.2 billion or
14%  increase in average  outstanding  loan  principal.  Average loan growth was
funded by a $1.3  billion or 13%  increase  in average  deposits.  The excess of
average  deposits  over  growth  in  average  loans  was  used to  reduce  other
borrowings,  generally  a  higher-costing  source  of  funds.  Table 1 shows the
effects on net  interest  revenue of changes in average  balances  and  interest
rates for the various types of earning assets and interest-bearing liabilities.

Net interest margin, the ratio of tax-equivalent net interest revenue to average
earning assets was 3.38% for the third quarter of 2006,  compared with 3.32% for
the third  quarter of 2005 and 3.40% for the second  quarter of 2006.  Yields on
average earning assets  continued to trend upwards due to rising market interest
rates.  The yield on  average  earning  assets was  6.91%,  up 108 basis  points
compared  with the third  quarter of 2005 and 20 basis points over the preceding
quarter.  The yield on average  outstanding loans was 7.99%, up 133 basis points
over the third  quarter of 2005 and 31 basis  points over the second  quarter of
2006. The tax-equivalent  yield on securities was 4.68% for the third quarter of
2006, compared with 4.31% for the third quarter of 2005 and 4.77% for the second
quarter of 2006.

Rates paid on average  interest-bearing  liabilities during the third quarter of
2006  increased  114 basis  points  over the third  quarter of 2005 and 25 basis
points  over the  preceding  quarter.  Rates  paid on  interest-bearing  deposit
accounts   increased   104  basis   points   over   2005.   The  cost  of  other
interest-bearing  funds increased 172 basis points compared with the same period
last year and 27 basis points from the preceding quarter. Capital,  non-interest
bearing funds and changes in the mix of funding sources added 45 basis points to
the net interest  margin in third  quarter of 2006 compared with 33 basis points
for 2005 and 42 basis points for the second quarter of 2006.

Our overall objective is to manage the Company's balance sheet to be essentially
neutral to changes in interest rate.  Approximately  78% of our commercial  loan
portfolio is either  variable  rate or fixed rate that will  reprice  within one
year.  These  loans are funded  primarily  by deposit  accounts  that are either
non-interest  bearing, or that reprice more slowly than the loans. The result is
a balance sheet that would be asset sensitive, which means that assets generally
reprice more  quickly  than  liabilities.  Among the  strategies  that we use to
achieve  a  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 expected duration of these securities is approximately 2.9
years  based  on a range  of  interest  rate  and  prepayment  assumptions.  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. We have
interest rate swaps with a combined

 4

notional amount of $797 million that convert fixed rate  liabilities to floating
rate based on LIBOR. The purpose of these derivatives, which generally have been
designated as fair value hedges,  is to position our balance sheet to be neutral
to changes in interest  rates.  We also have interest rate swaps with a notional
amount of $100 million that convert prime-based loans to fixed rate. The purpose
of these derivatives, which have been designated as cash flow hedges, also is to
position our balance sheet to be 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 Market Risk section of this
report.

Other Operating Revenue

Other operating  revenue increased $10.7 million compared with the third quarter
of last year.  Fees and  commission  revenue  increased  $2.7  million or 3%. In
addition,  $3.7 million of securities gains were recognized in the third quarter
of 2006 compared with securities  losses of $4.7 million in the third quarter of
2005.  Securities  gains and losses related  primarily to economic hedges of our
mortgage servicing rights.

Diversified sources of fees and commission revenue are a significant part of our
business  strategy and  represented  43% of total revenue,  excluding  gains and
losses on asset sales,  securities  and  derivatives,  for the third  quarter of
2006.  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.  We expect continued growth in
other  operating  revenue  through  offering  new  products  and services and by
expanding into new markets. However, increased competition and saturation in our
existing markets could affect the rate of future increases.

Fees and commissions revenue

Transaction  card  revenue  increased  $1.4  million or 8%.  Check card  revenue
increased $775 thousand or 19% while ATM network revenue increased $784 thousand
or 10% over the third  quarter of 2005.  During the third  quarter of 2006,  the
Company signed  agreements to place ATMs in 140 convenience  stores in Oklahoma,
Texas,  Missouri and Kansas.  Growth in check card revenue was distributed among
all markets.  Merchant discount fees decreased $146 thousand or 2% compared with
the third quarter of 2005.

 5

Trust fees and  commissions  increased $725 thousand or 4% for the third quarter
of  2006.  The  fair  value  of all  trust  assets,  which  is the  basis  for a
significant  portion of trust fees  increased to $29.7  billion at September 30,
2006  compared  with  $27.6  billion  at  September  30,  2005.  Personal  trust
management fees, which provide 30% of total trust fees and commissions increased
$288 thousand or 6%. Employee benefit plan management fees, which provide 20% of
total trust fees,  were  unchanged from 2005. Net fees from mutual fund advisory
and  administrative  services,  which provide 20% of total trust fees, were down
$97 thousand or 3%. In  addition,  revenue  from the  management  of oil and gas
properties and other real estate increased $319 thousand or 28%.

Trust activities in the Oklahoma and Colorado markets provided $12.6 million and
$2.1 million, respectively, of total trust fees and commissions during the third
quarter of 2006.  Trust revenue grew $218 thousand or 2% in the Oklahoma  market
and $233 thousand or 13% in the Colorado market.

Brokerage  and  trading  revenue  decreased  $408  thousand  or 4%.  Much of the
decrease in trading revenue is attributed to increased competition in the market
and lower demand caused by the flattening yield curve.  Customer hedging revenue
increased $513 thousand or 21% to $3.0 million. Volatility in the energy markets
prompted  our  energy  customers  to  more  actively  hedge  their  gas  and oil
production. Revenue from securities trading activities decreased $1.3 million or
20%.  Revenue from retail  brokerage  activities  increased $340 thousand or 12%
over the same period of 2005.

Service charges on deposit accounts increased $703 thousand or 3% over the third
quarter  of 2005.  Overdraft  fees grew  $915  thousand  or 5% due to  increased
volume.  Account  service  charge  revenue  decreased $206 thousand or 12%. This
decrease reflected the change in earnings credit available to commercial deposit
customers.  The earnings credit, which provides a non-cash method for commercial
customers  to avoid  incurring  charges for  deposit  services,  increases  when
interest rates rise.

Mortgage banking revenue,  which is discussed more fully in the Line of Business
- Mortgage Banking section of this report decreased $2.6 million or 27% compared
with 2005.  Net gains on mortgage  loans sold  totaled $2.9  million,  down $2.6
million from the third quarter of 2005.  Servicing  revenue totaled $4.0 million
for the third quarter of 2006, unchanged from the same period last year.

Other operating revenue included $2.9 million of fees earned on margin assets in
the third quarter of 2006 and $2.4 million in the third quarter of 2005.  Margin
assets which are held  primarily as part of the Company's  customer  derivatives
programs averaged $265 million for the third quarter of 2006, compared with $296
million  for the third  quarter of 2005.  Fees earned on average  margin  assets
increased to 4.33% in the third  quarter of 2006 from 3.27% in the third quarter
of 2005.  Fee rates  earned on  margin  assets  are  generally  consistent  with
short-term interest rates.

Other operating revenue also included investment banking revenue of $2.1 million
and $812  thousand  in the  third  quarters  of 2006 and 2005,  respectively.  A
recently  created tax exempt  leasing unit  provided $716 thousand of investment
banking revenue in the third quarter of 2006.

Securities and derivatives

BOK Financial  recognized  net gains of $3.7 million on securities for the third
quarter of 2006,  including net gains of $3.8 million on  securities  held as an
economic  hedge of mortgage  servicing  rights.  Securities  held as an economic
hedge of the mortgage servicing rights are separately  identified on the balance
sheet as "mortgage trading securities".  Mortgage trading securities are carried
at fair value;  changes in fair value are  recognized in earnings as they occur.
The  Company's  use of  securities  as an economic  hedge of mortgage  servicing
rights is  more-fully  discussed  in the Line of  Business  -  Mortgage  Banking
section  of this  report.  During  the  third  quarter  of 2005,  BOK  Financial
recognized net losses of $4.7 million,  substantially all due to securities held
as an economic hedge of mortgage servicing rights.  Excluding securities held as
an economic hedge of mortgage servicing rights, the Company recognized losses on
securities  of $39 thousand in the third quarter of 2006 and $58 thousand in the
third quarter of 2005.

Net gains on  derivatives  totaled $379  thousand for the third quarter of 2006,
compared  with net  gains of $606  thousand  in 2005.  Net  gains or  losses  on
derivatives  consist of fair value  adjustments  of  derivatives  used to manage
interest rate risk and the related hedged liabilities.

Year-to-date fees and commissions revenue

Fees and  commissions  revenue for the first nine months of 2006 totaled  $276.8
million, a $20.8 million or 8% increase

 6

over 2005.  Transaction card revenue increased $5.4 million or 10% due to volume
increases  in merchant  discounts  and debit card  transactions.  Trust fees and
commissions  increased  $4.1  million or 9% due to increase in asset  values and
business  growth.  Other revenue  increased $9.2 million or 38%,  including $4.0
million from margin account fees.

Other Operating Expense

Other operating expense for the third quarter of 2006 totaled $138.8 million,  a
$21.8  million  increase  from 2005.  The increase in other  operating  expenses
resulted  largely  from  changes  in the  value of  mortgage  servicing  rights.
Depreciation  of the fair value of mortgage  servicing  rights  during the third
quarter of 2006 increased  operating expenses $7.9 million.  Appreciation in the
value of mortgage  servicing rights decreased  operating expense by $4.7 million
in the third quarter of 2005.  Operating  expenses  increased $9.2 million or 8%
over the third  quarter  or 2005,  excluding  changes  in the value of  mortgage
servicing due to higher personnel expense.

Personnel expense

Personnel  expense  totaled $74.6 million for the third quarter of 2006 compared
with $66.5 million for the third quarter of 2005.

Regular  compensation  expense  which  consists  primarily of salaries and wages
totaled  $45.9  million for the third  quarter of 2006,  up $5.0  million or 12%
increase over 2005. The increase in regular compensation expense was due to a 8%
increase in average regular compensation per full-time equivalent employee and a
4% increase in average  staffing.  Growth in average  compensation per full-time
equivalent  employee reflects the cost of hiring top talent to support expansion
in the regional markets, product development, and technology support.

Incentive  compensation  expense  includes the  recognized  costs of  cash-based
commissions,  bonus and incentive programs,  stock-based  compensation plans and
deferred compensation plans.  Stock-based compensation plans include both equity
and liability awards.

Incentive  compensation  expense  totaled $16.5 million for the third quarter of
2006,  an increase of $2.8 million or 20% over 2005.  Third quarter 2006 expense
for the Company's various  cash-based  incentive programs totaled $13.2 million,
up  $1.9  million  over  last  year.   These  programs   consist   primarily  of
formula-based  plans that determine  incentive amounts based on  pre-established
growth criteria. Compensation expense for stock-based compensation plans totaled
$2.8 million for both the third quarters of 2006 and 2005.  Compensation expense
for stock-based  compensation  plans accounted for as equity awards totaled $1.6
million in the third  quarter of 2006,  compared  with $1.5 million in the third
quarter of 2005.  Expense for these awards is determined  by award's  grant-date
fair value and is not affected by subsequent  changes in the market value of BOK
Financial common stock.  Compensation expense for stock-based compensation plans
accounted for as liability  awards  totaled $1.2 million in the third quarter of
2006, compared with $965 thousand in 2005. Expense for these liability awards is
based on current fair value,  including current period changes due to the market
value of BOK Financial common stock.

 7

Employee  benefit  expenses  totaled $11.0 million for the third quarter of 2006
and $10.4 million for the third quarter of 2005.  Pension expense decreased $1.8
million due to the curtailment of pension plan benefits as of April 1, 2006. The
reduction in pension  expense was largely  offset by a $1.2 million  increase in
the cost of enhanced  employee thrift plan benefits and a $698 thousand increase
in employee insurance costs.

Data processing and communications expense

Data  processing and  communication  expenses  decreased  $561  thousand,  or 3%
compared to 2005. This expense consists of two broad categories, data processing
systems and transaction card processing. Data processing systems costs decreased
$465  thousand,  or 4%  compared  with the third  quarter of 2005.  The  Company
negotiated cost  reductions on its primary data  processing  contract during the
quarter in exchange for a three-year  contract  extension.  The benefit of these
cost reductions will be recognized over the remaining contract term. Transaction
card processing costs decreased $97 thousand or 1%.

Other operating expenses

Other expenses  increased $1.5 million or 21% compared with the third quarter of
2005 due to a $1.8 million  non-cash  charge  related to taxes on a $202 million
investment  in  bank-owned  life  insurance.  These  taxes,  which  totaled $8.2
million,  will be  credited to the  Company  over the next ten years.  The third
quarter charge reduced the tax asset to its present value of $6.4 million.

Year to date  operating  expenses  totaled  $378.3  million,  up 10% over  2005.
Personnel costs were up $27.9 million or 15%. Salaries and wages increased $14.8
million or 12% due to a 7% increase in average  salaries  per  employee and a 4%
increase in the average number of employees.  Incentive compensation expense was
up  $11.3  million.   Cash-based  incentive  programs  increased  $6.9  million.
Stock-based incentive compensation increased $4.4 million.

Income Taxes

Income tax expense was $24.8  million or 32% of book  taxable  income,  compared
with $27.8 million or 35% of book taxable  income for the third quarter of 2005.
The statute of limitations expired on an uncertain tax position during the third
quarter of 2006.  Income  tax  expense  was  reduced  by $2.2  million  from the
reversal of reserves previously  established for this uncertainty.  In addition,
income tax expense in the third  quarter of 2006 was reduced by $800 thousand to
adjust 2006 estimated year-to-date tax expense.

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.

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

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

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

Consolidated net income provided by the Regional  Banking Division  continued to
increase due largely to asset growth.  Also,  performance by business units that
generate  deposits for the Company,  such as the Oklahoma  consumer banking unit
continued  to improve due  primarily  to internal  funds  pricing  credits.  The
increased  value of  deposits  when  short-term  interest  rates  are  rising is
reflected  in the internal  transfer  pricing  credit.  The increase in internal
transfer pricing credit is offset through the funds management unit.

Oklahoma Corporate Banking

The Oklahoma  Corporate  Banking Division  provides loan and lease financing and
treasury and cash  management  services to  businesses  throughout  Oklahoma and
certain  relationships in surrounding states. In addition to serving the banking
needs of small  businesses,  middle  market and larger  customers,  the Oklahoma
Corporate  Banking  Division has specialized  groups that serve customers in the
energy,  agriculture,  healthcare and banking/finance  industries,  and includes
TransFund, our electronic funds transfer network. The Oklahoma Corporate Banking
Division  contributed  $20.6 million or 39% to  consolidated  net income for the
third quarter of 2006. This compares to $17.1 million or 34% of consolidated net
income for 2005.  Growth in net income  provided by this division came primarily
from loan and deposit growth. Average loans attributed to the Oklahoma Corporate
Banking Division were $4.3 billion for the third quarter of 2006,  compared with
$4.1  billion for the third  quarter of 2005.  Deposits  attributed  to Oklahoma
Corporate  Banking  averaged $1.8 billion for the third quarter of 2006, up $123
million or 7% over last year.  Increased  average loans and

 9

deposits  combined to  increase  net  interest  revenue  $2.2  million or 6%. In
addition, other operating revenue increased $730 thousand or 3% due to growth in
ATM processing fees. Operating expenses decreased $770 thousand or 3%. Personnel
expense increased $1.3 million or 15% due to growth in both regular salaries and
incentive compensation. Allocations for shared services decreased $2.7 million.

Mortgage Banking

BOK Financial  engages in mortgage banking  activities  through the BOk Mortgage
Division  of  Bank  of  Oklahoma.  These  activities  include  the  origination,
marketing and servicing of conventional and government-sponsored mortgage loans.
Mortgage  banking  activities  lost $2.0  million in the third  quarter of 2006,
compared with a net profit of $252 thousand in 2005.

Mortgage banking activities  consisted of two sectors,  loan production and loan
servicing.  The loan  production  sector  generally  performs best when mortgage
rates are relatively low and loan origination volumes are high. Conversely,  the
loan servicing sector generally performs best when mortgage rates are relatively
high and  prepayments  are low. The general  trend toward  higher  mortgage loan
commitment  rates in the first half of 2006  shifted  to a  decrease  during the
third quarter.

Loan Production Sector

Loan  production  revenue  totaled $3.4  million for the third  quarter of 2006,
including  $3.1  million of  capitalized  mortgage  servicing  rights and a $730
thousand net loss on loans sold.  Loan  production  revenue totaled $5.8 million
for the  third  quarter  of 2005 due to $5.8  million  of  capitalized  mortgage
servicing  rights.  Mortgage  loans funded in the third  quarter of 2006 totaled
$230 million,  including $199 million of loans funded for resale and $30 million
of loans funded for retention by  affiliates.  Mortgage loans funded in the same
period of 2005  totaled  $247  million.  Approximately  67% of the loans  funded
during the third quarter of 2006 was to borrowers in Oklahoma.  Loan  production
activities resulted in net pre-tax income of $249 thousand for the third quarter
of 2006 and net pre-tax  income of $2.1  million for the third  quarter of 2005.
The pipeline of mortgage loan applications totaled $240 million at September 30,
2006,  compared with $276 million at June 30, 2006 and $290 million at September
30, 2005.

Loan Servicing Sector

The loan  servicing  sector had a net pre-tax loss of $3.8 million for the third
quarter of 2006  compared  to a net  pre-tax  loss of $1.7  million for the same
period of 2005. The fair value of mortgage  servicing  rights  decreased in 2006
due to a decrease in mortgage  commitment  rates and related  factors.  The fair
value of mortgage  servicing  rights  increased during the third quarter of 2005
due to rising mortgage commitment rates.

Average mortgage commitment rates decreased 52 basis points since June 30, 2006.
This decrease in commitment  rates  combined with  increased  discount rates and
anticipated  prepayment  speeds to reduce the fair value of  mortgage  servicing
rights by $7.9 million.  At the same time, gains of $3.8 million were recognized
from  increases in the fair value of financial  instruments  held as an economic
hedge of the value of the servicing rights.

During the third  quarter of 2005, a $4.7 million  reversal of the allowance for
impairment of mortgage loan servicing

 11

rights was  recognized.  A 50 basis point  increase in mortgage  interest  rates
during  this  period  increased  the fair  value of the  servicing  rights.  The
impairment  provision  reversal  was  offset by net  losses of $5.0  million  on
financial instruments designated as economic hedges.

Servicing  revenue,  which  is  included  in  mortgage  banking  revenue  on the
Consolidated  Statements  of  Earnings,  totaled  $4.0 million in both the third
quarters of 2006 and 2005. The average outstanding balance of loans serviced for
others was $4.5  billion  during 2006  compared  to $3.9  billion  during  2005.
Annualized  servicing  revenue per  outstanding  loan principal  decreased to 36
basis points for the third  quarter of 2006,  compared with 42 basis points last
year.

In  addition to changes in the fair value of  mortgage  servicing  rights due to
anticipated  prepayments and other factors, the fair value of mortgage servicing
rights  decreased  $2.5 million  during the third  quarter of 2006 due to actual
runoff  of the  underlying  loans  serviced.  This  reduction  in fair  value is
included in mortgage banking costs in the  Consolidated  Statements of Earnings.
Prior to adoption of FAS 156 in the first  quarter of 2006,  mortgage  servicing
rights were  amortized in proportion to projected  cash flows over the estimated
life of the loans  serviced.  Projected  cash flows  considered  both actual and
estimated  runoff  of  the  underlying  loans  serviced.   Amortization  expense
recognized  in mortgage  banking  costs during the third quarter of 2005 totaled
$3.8 million.  The decrease in expense  related to the runoff of loans  serviced
primarily reflects lower loan prepayment speeds.

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

At September 30, 2006,  financial  instruments with a fair value of $112 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, 2006,  the pre-tax  results of this
modeling on reported earnings were:

Table 8 shows the non-linear  effect of changes in mortgage  commitment rates on
the value of mortgage  servicing  rights.  A 50 basis point increase in rates is
expected to increase  value by $3.8 million  while a 50 basis point  decrease is
expected to reduce value by $4.4 million.  This considers that there is an upper
limit to appreciation in the value of servicing  rights as rates rise due to the
contractual  repayment terms of the loans and other factors.  There is much less
of a limit on the speed at which  mortgage  loans may prepay in a declining rate
environment.

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

Modeling  changes in value of the  mortgage  servicing  rights due to changes in
interest rates assumes stable  relationships  between mortgage  commitment rates
and discount rates used to determine the present value of future cash flows.  It
also assumes a stable  relationship  between assumed loan prepayments and actual
prepayments  of our  loans.  Based on  these  assumptions,  at June 30,  2006 we
expected the value of our servicing  rights to decrease $3.7 million if mortgage
commitment  rates fell 50 basis  points.  As noted before,  mortgage  commitment
rates  fell 52 basis  points  and the  value of our  mortgage  servicing  rights
decreased  $7.9 million.  We believe two factors  caused most of the  difference
between our expectation and the actual results.  First,  mortgage interest rates
have been very volatile over the past six months,  rising 36 basis points during
the second  quarter of 2006,  then falling 52 basis points in the third quarter.
This volatility increased the discount spread that investors in servicing rights
would expect relative to market interest rates by 34 basis points over benchmark
rates.  The increased  discount spread reduced the value of our servicing rights
by $1.0 million.  Second,  actual  prepayments of loans we service  increased in
relation to forecasted prepayment speeds.  Historically,  our actual prepayments
have been approximately 76% of prepayments  forecasted based on national trends.
Based on a  moving  average  of the  most  recent  twelve-month  period,  actual
prepayments  increased  to 80%. The increase in  prepayment  speeds  reduced the
value of our servicing rights by $3.2 million.

programs are included in the Wealth Management Division.

Wealth Management contributed $6.1 million or 12% to consolidated net income for
the  third  quarter  of  2006.  This  is  compared  to  $5.9  million  or 12% of
consolidated net income for 2005. Trust and private financial  services provided
$5.4 million of net income in the third  quarter of 2006,  up 2% over last year.
Net income provided by brokerage and trading activities totaled $766 thousand, a
$206 thousand or 37% increase compared with the third quarter of 2005.

Average loans attributed to trust and private financial  services increased $206
million or 40% compared with the third  quarter of 2005.  Loan growth was funded
by a $108 million  increase in average  deposits and funds provided by the funds
management  unit.  The increase in loans and  deposits  combined to increase net
interest revenue by $2.1 million or 43%.

 13

Other operating revenue for the third quarter of 2006 totaled $29.8 million,  up
$1.8 million or 6% over 2005. Other operating  revenue for the wealth management
division consists  primarily of trust fees and commissions,  investment  banking
revenue and brokerage and trading revenue.

Trust fees and commissions  totaled $15.0 million for the third quarter of 2006,
a $457 thousand or 3% increase  over 2005.  At September 30, 2006 and 2005,  the
wealth  management  line of  business  was  responsible  for trust  assets  with
aggregate market values of $27.2 billion and $25.2 billion, respectively,  under
various fiduciary  arrangements.  The growth in trust assets reflected increased
market value of assets managed in addition to new business  generated during the
year. We have sole or joint discretionary  authority over $10.1 billion of trust
assets at September 30, 2006, compared with $9.1 billion at September 30, 2005.

Investment banking revenue increased $1.3 million over the third quarter of 2005
due the timing of  transaction  closings  and growth in a  recently-created  tax
exempt leasing unit.

Revenue from our customer hedging programs was up $879 thousand or 57% over last
year due largely to volatility in energy prices. Retail brokerage fees increased
$317 thousand or 11%. This revenue  growth was largely  offset by a $1.3 million
decrease in securities  trading profits due to increased  competition and a flat
yield curve.

Operating  expenses  totaled $26.6 million for the third quarter of 2006, a $3.4
million or 15% increase over 2005.  Personnel costs rose $2.2 million or 15% due
primarily to higher costs in trust and private financial services.

Regional Banking

Regional  Banking  consists  primarily of the corporate and  commercial  banking
services  provided  by Bank of Texas,  Bank of  Albuquerque,  Bank of  Arkansas,
Colorado State Bank and Trust, and Bank of Arizona in their respective  markets.
They also include fiduciary  services provided by Colorado State Bank and Trust.
Small  businesses and  middle-market  corporations  are Regional Banking primary
customer  focus.   Regional  Banking   contributed   $22.2  million  or  42%  to
consolidated  net income  during the third  quarter of 2006.  This compares with
$18.5  million or 36% of  consolidated  net income for the same  period in 2005.
Growth in net income  contributed  by the  regional  banks came  primarily  from
operations in Texas. Net income from Texas operations  increased $1.6 million or
15% compared with the same period of 2005.  In addition,  net income for 2006 in
Colorado,  New Mexico and Arizona increased $1.4 million, $402 thousand and $514
thousand, respectively. Net income in Arkansas decreased $250 thousand from last
year.

Net income from operations in Colorado was $2.9 million for the third quarter of
2006,  compared  with $1.5 million for the third  quarter of 2005.  Net interest
revenue  increased $2.1 million or 29% due primarily to a $425 million  increase
in average  earning  assets.  Average loans increased $133 million while average
securities  increased  $292  million.  The growth in  earning  assets was funded
primarily by a $276 million  increase in deposits and $131 million of borrowings
from the funds management  unit.  Other operating  revenue grew $362 thousand or
15% due primarily to trust fees and commissions. At September 30, 2006 and 2005,
Colorado regional banking was responsible for trust assets with

 14

aggregate  fair values of $2.6  billion and $2.4  billion,  respectively,  under
various fiduciary  arrangements.  We have sole or joint discretionary  authority
over $980  million of trust assets at September  30,  2006,  compared  with $903
million at September 30, 2005. Operating expenses increased $988 thousand or 15%
including a $521 thousand or 18% increase in personnel costs.

Net income from Texas operations  totaled $12.8 million for the third quarter of
2006,  up $1.6  million or 15% over last year.  Net  interest  revenue grew $4.9
million or 15%. Average earning assets  increased $543 million,  or 19% from the
third quarter of 2005.  This increase  resulted from a $420 million  increase in
average loans and a $128 million  increase in securities.  The growth in average
earning  assets was  funded  primarily  by a $489  million  increase  in average
deposits.  Operating expenses increased $496 thousand or 2%. An $816 thousand or
7% increase in personnel  costs and a $457 thousand  charge  related to taxes on
bank-owned life insurance was partially offset by an $836 thousand  reduction in
higher  allocations for shared services.  Net loans charged off during the third
quarter of 2006  included $1.6 million of  commercial  overdrafts  from a single
customer.

Net income from New Mexico  operations  increased  $402 thousand or 8%.  Average
earning assets decreased $64 million.  Average loans increased $20 million while
securities  and funds sold to the funds  management  unit decreased $87 million.
Average deposits in the New Mexico market increased $114 million, including $112
million of consumer  banking  deposits.  Average  funds  borrowed  from external
sources  decreased  $143  million as the  Company  centralized  borrowings  from
external sources in the funds management unit. Operating expenses decreased $232
thousand or 3%.

We continue to expand  operations in the Arizona market since the acquisition of
Bank of Arizona in the second quarter of 2005.  Outstanding  loans attributed to
the Arizona market  averaged $344 million for the third quarter of 2006, up $166
million  from the third  quarter  of 2005's  average of $177  million.  Deposits
averaged $126 million for both the third quarters of 2006 and 2005.  Loan growth
was funded by borrowings  from the funds  management  unit.  Operating  expenses
increased  $513  thousand or 16%.  Personnel  costs were up $985  thousand as we
continue to build a commercial banking presence in Phoenix and Tucson. Growth in
personnel  costs was  partially  offset  by a $585  thousand  reduction  in data
processing expense.

Financial Condition

Securities

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

The  amortized  cost of available  for sale  securities  totaled $4.8 billion at
September 30, 2006 and $4.9 billion at June 30, 2006. Mortgage-backed securities
continued to represent  substantially  all  available  for sale  securities.  As
previously discussed in the Net Interest Revenue section of this report, we hold
mortgage backed  securities as part of our overall interest rate risk management
strategy.

The primary  risk of holding  mortgage-backed  securities  comes from  extension
during periods of rising interest rates or prepayment  during periods of falling
interest  rates. We evaluate this risk through  extensive  modeling of risk both
before  making  an  investment  and  throughout  the life of the  security.  The
effective duration of the mortgage-backed securities portfolio was approximately
2.9  years at  September  30,  2006 and 3.1 years at June 30,  2006.  Management
estimates  that  the  effective  duration  of  the  mortgage-backed   securities
portfolio  would extend to 3.4 years  assuming a 300 basis point  immediate rate
shock.

Net unrealized  losses on available for sale securities  totaled $121 million at
September 30, 2006 compared with net  unrealized  losses of $187 million at June
30,  2006.  The  decrease in net  unrealized  losses  during the quarter was due
primarily to falling  interest  rates.  The aggregate gross amount of unrealized
losses  at  September  30,  2006 was $127  million,  down $74  million  from the
previous  quarter's end.  Management  evaluated the securities  with  unrealized
losses  to  determine  if we  believe  that  the  losses  were  temporary.  This
evaluation  considered  factors  such as causes  of the  unrealized  losses  and
prospects  for recovery over various  interest rate  scenarios and time periods.
Management does not believe that any of the unrealized  losses are due to credit
quality  concerns.  We also  considered our intent and ability to either hold or
sell the securities.  It is management's  belief,  based on currently  available
information and our evaluation,  that the unrealized  losses in these securities
are temporary.

Bank-Owned Life Insurance

During  the  third  quarter  of 2006,  the  Company  invested  $202  million  in
bank-owned  life  insurance.  This investment is expected to provide a long-term
source of earnings to support existing employee benefit plans. Substantially all
of the funds are held in separate  accounts  and  invested  in U.S.  government,
mortgage-backed  and corporate debt securities.  The cash surrender value of the
life  insurance  policies is further  supported  by a stable  value wrap,  which
protects  against  changes  in the  fair  value  of the  investments.  The  cash
surrender  value of the policies,  including the value of the stable value wrap,
was $194  million at  September  30,  2006.  In  addition to  investment  in the
separate  accounts,  $8.2  million  of the  amount  invested  paid  taxes on the
insurance premiums. These taxes will be recovered over a ten-year period. A $6.4
million  receivable  based on the present  value of the taxes was recorded as of
September 30, 2006.

Loans

The aggregate loan portfolio at September 30, 2006 totaled $10.0 billion, a $211
million  increase since June 30, 2006, a 9% annualized  rate.  Commercial  loans
increased $138 million while  mortgage and consumer loans  increased $35 million
and $36 million,  respectively.  Commercial real estate loans were substantially
unchanged during the quarter.

The  commercial  loan  portfolio  totaled $5.7 billion at June 30, 2006.  Energy
loans  totaled  $1.5  billion or 15% of total  loans.  Outstanding  energy loans
increased $24 million, or 6% annualized,  during the third quarter of 2006 after
increasing $147 million during the preceding quarter. Approximately $1.3 billion
of loans in the energy  portfolio  was to oil and gas  producers.  The amount of
credit  available to these  customers  generally  depends on a percentage of the
value of their proven energy  reserves based on anticipated  prices.  The energy
category also included  loans to borrowers  involved in the  transportation  and
sale of oil and gas and to borrowers that manufacture equipment or provide other
services to the energy  industry.  The services sector of the portfolio  totaled
$1.4 billion,  or 14% of the Company's total  outstanding  loans.  Loans in this
sector of the portfolio  increased  $27 million or 8% annualized  since June 30,
2006.  The services  sector  consists of a large number of loans to a variety of
businesses,  including  communications,   gaming  and  transportation  services.
Approximately  $1.0  billion  of the  services  sector is made up of loans  with
balances of less than $10 million.

Other  notable loan  concentrations  by primary  industry of the  borrowers  are
presented in Table 15.

BOK Financial participates in shared national credits when appropriate to obtain
or maintain business relationships with local customers. Shared national credits
are defined by banking  regulators  as credits of more than $20 million and with
three or more non-affiliated  banks as participants.  The outstanding  principal
balances of these loans  totaled  $1.3  billion at  September  30, 2006 and $1.2
billion at June 30,  2006.  Substantially  all of these loans were to  borrowers
with local market  relationships.  BOK  Financial  serves as the agent lender in
approximately  28% of the shared national credits,  based on dollars  committed.
Our  lending  policies  generally  avoid  loans  in  which  we do not  have  the
opportunity  to  maintain  or  achieve  other  business  relationships  with the
customer.

Commercial  real estate loans totaled $2.3 billion or 23% of the loan  portfolio
at September  30, 2006.  Construction  and land  development  loans totaled $826
million,  up $36 million over June 30, 2006.  Construction  and land development
included  $643 million of loans secured by single  family  residential  lots and
premises,  up $35 million from the previous  quarter's end. The major components
of other  commercial real estate loans were office  buildings - $413 million and
retail facilities - $364 million.

Residential  mortgage loans,  excluding  mortgage loans held for sale,  included
$374  million of home  equity  loans,  $392  million of loans held for  business
relationship  purposes,  $257  million of  adjustable  rate  mortgages  and $167
million of loans held for community  development.  Consumer  loans included $427
million of indirect automobile loans. Indirect

 19

auto loans have  increased $31 million since June 30, 2006.  Approximately  $366
million of these loans were  purchased  from dealers in Oklahoma.  Growth during
the quarter  included $16 million from indirect  lending  activities in Arkansas
and $15 million in Oklahoma.

Loan Commitments

BOK Financial enters into certain  off-balance sheet  arrangements in the normal
course of business.  These arrangements  included loan commitments which totaled
$5.0  billion  and  standby  letters of credit  which  totaled  $473  million at
September 30, 2006. 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  represent  future
cash requirements.

Derivatives with Credit Risk

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

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

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

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

Derivative  contracts are carried at fair value. At September 30, 2006, the fair
value of derivative  contracts  reported as assets under these programs  totaled
$321 million.  This included energy  contracts with fair values of $292 million,
interest  rate  contracts  with fair values of $21 million and foreign  exchange
contracts  with  fair  values  of $7  million.  The  aggregate  fair  values  of
derivative contracts reported as liabilities totaled $328 million. Approximately
77% of the fair value of asset contracts was with customers.  The credit risk of
these contracts is generally backed by energy production.  The remaining 23% was
with dealer  counterparties.  The maximum net exposure to any single customer or
counterparty totaled $51 million.

Summary of Loan Loss Experience

The reserve for loan losses, which is available to absorb losses inherent in the
loan  portfolio,  totaled $105 million at September  30, 2006 and June 30, 2006,
and $110 million at September 30, 2005. These amounts  represented  1.06%, 1.07%
and 1.24% of outstanding loans,  excluding loans held for sale, at September 30,
2006, June 30, 2006 and September 30, 2005,  respectively.  Losses on loans held
for sale,  principally  mortgage loans  accumulated  for placement into security
pools,  are charged to earnings  through  adjustment in the carrying value.  The
reserve  for  loan  losses  also  represented  347% of  outstanding  balance  of
non-accruing  loans at September  30, 2006,  compared with 337% at June 30, 2006
and 293% at  September  30,  2005.  Non-accruing  loans  totaled  $30 million at
September  30, 2006,  compared with $31 million at June 30, 2006 and $37 million
at September  30, 2005.  Net loans  charged off during the third quarter of 2006
totaled $4.3  million,  up from $3.8  million in the second  quarter of 2006 and
$3.3 million for the third quarter of 2005.

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

reserve for  off-balance  sheet credit losses would decrease and the reserve for
loan losses would increase as outstanding commitments are funded.

Specific  impairment  reserves are  determined  through  evaluation of estimated
future  cash  flows and  collateral  value.  At  September  30,  2006,  specific
impairment  reserves  totaled  $3.7  million  on total  impaired  loans of $27.4
million.  Required  specific  impairment  reserves were $3.3 million at June 30,
2006.

Nonspecific  reserves are  maintained  for risks beyond  factors  specific to an
individual  loan or those  identified  through  migration  analysis.  A range of
potential losses is determined for each risk factor identified. At September 30,
2006, the ranges of potential losses for the more significant factors were:

General economic conditions - $4.8 million to $8.5 million
Concentration in large loans - $1.4 million to $2.8 million

The provision  for credit  losses  totaled $5.3 million for the third quarter of
2006, compared with $3.8 million for the second quarter of 2006 and $4.0 million
for the third quarter of 2005.  Factors  considered in determining the provision
for  credit  losses  included  an  increase  in net losses  during the  quarter,
partially offset by decreases in the outstanding  balances of classified  loans.
Net  losses  during  the third  quarter  included  $1.6  million  of  commercial
overdraft  charge-offs while recoveries included $300 thousand received from the
sale of rights to pursue collection of old defaulted loans.

Nonperforming Assets

Information  regarding  nonperforming  assets,  which  totaled  $41  million  at
September  30, 2006 and $39 million at June 30, 2006,  is presented in Table 18.
Nonperforming  assets included  non-accrual  loans and excluded loans 90 days or
more past due but still accruing interest. Non-accrual loans totaled $30 million
at  September  30,  2006 and $31  million  at June 30,  2006.  Newly  identified
non-accruing  loans  totaled  $6  million  during  the  third  quarter  of 2006.
Non-accruing loans decreased $4 million for loans charged off or foreclosed, and
$3 million for cash payments received.

The loan review process also identifies  loans that possess more than the normal
amount of risk due to deterioration  in the financial  condition of the borrower
or the value of the  collateral.  Because the borrowers are still  performing in
accordance  with  the  original  terms of the  loan  agreements,  and no loss of
principal  or  interest  is  anticipated,  these  loans  were  not  included  in
Nonperforming Assets. Known information,  however, causes management concerns as
to the  borrowers'  ability  to  comply  with  current  repayment  terms.  These
potential  problem  loans  totaled  $25  million at  September  30, 2006 and $23
million at June 30, 2006.  Potential  problem loans by primary industry included
healthcare - $11 million, services - $6 million and manufacturing - $5 million.

Deposits

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

Total  deposits  averaged  $11.4  billion for the third quarter of 2006, up $171
million,  or 6% annualized  compared with average deposits in the second quarter
of 2006.  Average  commercial  deposits  increased  $199 million  consisting  of
increases of $163 million in Texas and $39 million in Oklahoma. Average deposits
attributed to consumer banking  increased $90 million,  including $29 million in
Colorado, $26 million in New Mexico and $24 million in Oklahoma.

 24

Average  deposits  attributed  to  wealth  management  decreased  $125  million.
Oklahoma wealth management  deposits  decreased $147 million.  Funds received in
late 2005 had temporarily  been held in a deposit  account pending  reinvestment
opportunities.  The  decrease in wealth  management  deposits  in  Oklahoma  was
partially  offset by a $23 million  increase in Colorado.  In addition,  average
deposits  attributed to mortgage  banking,  which consisted  primarily of escrow
funds, increased $13 million.

Core  deposits,  which we define as  deposits of less than  $100,000,  excluding
public funds and brokered deposits,  averaged $5.5 billion for the third quarter
of 2006, an annualized  increase of 6%.  Average core deposits  comprised 49% of
total deposits for the third quarter of 2006.  Deposit accounts with balances in
excess of $100,000  increased at a 12% annualized rate to $4.7 billion or 42% of
total  average  deposits  for the third  quarter of 2006.  Average  public funds
decreased  $43 million or 26%  annualized  from  seasonal  changes  based on the
timing of tax receipts.

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

Borrowings and Capital

BOK Financial  (parent company) has a $100 million  unsecured  revolving line of
credit  with  certain  banks  that  expires  in  December  2010.  There  was  no
outstanding  principal  balance on this credit  agreement at September 30, 2006.
Interest  is based on LIBOR  plus a defined  margin  that is  determined  by the
Company's  credit  rating or a base rate.  This  margin  ranges  from  0.375% to
1.125%.  The margin  currently  applicable  to  borrowings  against this line is
0.500%.  The base rate is defined as the greater of the daily federal funds rate
plus 0.500% or the SunTrust Bank prime rate. Interest is generally paid monthly.
Facility  fees are paid  quarterly on the unused  portion of the  commitment  at
rates that range from 0.100% to 0.250% based on the Company's credit rating.

This credit  agreement  includes  certain  restrictive  covenants that limit the
Company's  ability to borrow  additional  funds, to make  investments and to pay
cash dividends on common stock.  These  covenants also require BOK Financial and
subsidiary  banks to maintain  minimum  capital levels and to exceed minimum net
worth ratios.  BOK Financial met all of the  restrictive  covenants at September
30, 2006.

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  $199  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 $129
million under this policy.

Equity capital for BOK Financial  totaled $1.7 billion at September 30, 2006, up
$87  million  during  the  quarter.  Retained  earnings,  net  income  less cash
dividends provided $43 million of the increase.  Accumulated other comprehensive
losses  decreased  $44 million due  primarily to a reduction  in net  unrealized
losses on available for sale securities.

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. A maximum of two million common
shares may be repurchased.  The specific timing and amount of shares repurchased
will vary  based on market  conditions,  securities  law  limitations  and other
factors.  Repurchases  may be  made  over  time  in  open  market  or  privately
negotiated   transactions.   The   repurchase   programs  may  be  suspended  or
discontinued at any time without prior notice. During the third quarter of 2006,
the Company  repurchased  71,447 common shares at an average price of $51.82 per
share.  The Company may repurchase 1.7 million common shares in the future under
this program.

Cash  dividends of $10.0  million or $0.15 per common share were paid during the
third  quarter of 2006.  On October  31,  2006 the Board of  Directors  approved
quarterly cash dividend of $0.15 per common share.  The dividend will be payable
on or about November 30, 2006 to shareholders of record on November 13, 2006.

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

For a banking institution to qualify as well capitalized,  its Tier 1, Total and
Leverage  capital ratios must be at least 6%, 10% and 5%,  respectively.  All of
the Company's banking  subsidiaries  exceeded the regulatory  definition of well
capitalized.  The capital ratios for BOK Financial on a  consolidated  basis are
presented in Table 20.

Off-Balance Sheet Arrangements

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

The Company will have no  obligation  to issue  additional  common shares or pay
cash to satisfy any benchmark  price  protection  obligation if the market value
per share of BOK  Financial  common stock  remains  above the highest  benchmark
price of $42.53.  The closing price of BOK  Financial  common stock on September
30, 2006 was $49.50 per share.

Market Risk

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

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

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

Interest Rate Risk - Other than Trading

BOK Financial  has a large portion of its earning  assets in variable rate loans
and a large portion of its  liabilities in demand deposit  accounts and interest
bearing  transaction  accounts.  Changes in interest  rates affect these earning
assets  more  rapidly  than  interest  bearing  liabilities  in the short  term.
Management  has adopted  several  strategies to position the balance sheet to be
neutral to  interest  rate  changes.  As  previously  noted in the Net  Interest
Revenue section of this report,  management  acquires securities that are funded
by borrowings in the capital  markets.  The average duration of these securities
is expected to be approximately  2.9 years based on a range of interest rate and
prepayment assumptions.

BOK  Financial  also uses  interest  rate swaps in managing  its  interest  rate
sensitivity. These products are generally used to more closely match interest on
certain  variable-rate loans with funding sources and long-term  certificates of
deposit  with earning  assets.  During the third  quarter of 2006,  net interest
revenue  was  reduced  by  $2.8  million  from  periodic  settlements  of  these
contracts.  Net interest  revenue was  decreased by $367  thousand from periodic
settlements of these contracts in the third quarter of 2005. These contracts are
carried  on the  balance  sheet at fair  value  and  changes  in fair  value are
reporting in income as derivatives  gains or losses. A net gain of $379 thousand
was recognized in the third

 28

quarter of 2006  compared to a net gain of $606  thousand in same period of 2005
from  adjustments of these swaps and hedged  liabilities  to fair value.  Credit
risk from  interest  rate  swaps is  closely  monitored  as part of our  overall
process of managing credit exposure to other financial institutions.

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

The Company's  primary interest rate exposures  included the Federal Funds rate,
which affects short-term borrowings, and the prime lending rate and LIBOR, which
are the basis for much of the variable-rate loan pricing. Additionally, mortgage
rates directly affect the prepayment speeds for  mortgage-backed  securities and
mortgage servicing rights.  Derivative financial instruments and other financial
instruments   used  for  purposes  other  than  trading  are  included  in  this
simulation.  The model incorporates assumptions regarding the effects of changes
in interest rates and account balances on indeterminable maturity deposits based
on a combination  of historical  analysis and expected  behavior.  The impact of
planned  growth and new  business  activities  is factored  into the  simulation
model.  The  effects  of  changes  in  interest  rates on the value of  mortgage
servicing  rights are excluded from Table 21 due to the extreme  volatility over
such a large rate range.  The effects of interest  rate  changes on the value of
mortgage  servicing  rights and  securities  identified  as economic  hedges are
presented in the Lines of Business - Mortgage Banking section of this report.

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

Trading Activities

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

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

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

limit the VAR to $1.8 million. At September 30, 2006, the VAR was $717 thousand.
The greatest value at risk during the quarter was $717 thousand.

Controls and Procedures

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

Forward-Looking Statements

This report contains  forward-looking  statements that are based on management's
beliefs, assumptions, current expectations, estimates, and projections about BOK
Financial,  the financial  services  industry and the economy in general.  Words
such as "anticipates," "believes," "estimates," "expects," "forecasts," "plans,"
"projects,"  variations  of such words and similar  expressions  are intended to
identify such forward-looking  statements.  Management judgments relating to and
discussion of the provision and reserve for loan losses 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 (Liabilities

(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.,
and BOSC, Inc. Certain prior period amounts have been reclassified to conform to
current  period  classification.  Reclassification  affecting  the  Consolidated
Balance  Sheet as of December 31, 2005 included an increase in other assets from
$341 million to $415 million and accrued  interest,  taxes and expenses from $18
million to $92 million. This reclassification consistently presents deferred tax
assets for all periods presented.

The financial  information  should be read in conjunction  with BOK  Financial's
2005 Form 10-K filed with the Securities and Exchange Commission, which contains
audited  financial  statements.  Amounts  presented as of December 31, 2005 have
been derived from BOK Financial's 2005 Form 10-K.

Newly Adopted and Pending Accounting Policies

BOK Financial  adopted  Statement of Financial  Accounting  Standards No. 123-R,
"Share-Based  Payments"  ("FAS 123-R") as of January 1, 2006. FAS 123-R requires
companies to recognize in income  statements the grant-date  fair value of stock
options and other  equity-based  compensation  issued to employees.  Share-based
payments that will settle in equity  instruments are measured at grant-date fair
value and not remeasured for  subsequent  changes in fair value.  FAS 123-R also
requires that share-based payments that meet specified criteria to be classified
as liability  awards and carried at current fair value.  Fair value of liability
awards are remeasured at each balance sheet date until the award is settled. BOK
Financial had  previously  adopted the preferred  income  statement  recognition
methods of the original FAS 123  retroactively to its effective date of December
15, 1994. The adoption of FAS 123-R did not  significantly  affect the Company's
financial statements.

Stock options  outstanding  at September 30, 2006 totaled  3,609,303,  including
686,887 of vested options and 2,922,416 of unvested options.  Management expects
that  approximately  2.9 million of the unvested  options will vest according to
their  contractual  terms.  The weighted  average  exercise prices of vested and
unvested options are $26.45 and $40.27, respectively.

The intrinsic value of options  exercised during the three and nine months ended
September  30,  2006  was  $3.6  million  and $9.4  million,  respectively.  The
intrinsic  value of options  exercised  during the three and nine  months  ended
September 30, 2005 was $2.8 million and $7.3 million,  respectively. The Company
received cash  proceeds  from stock  options  exercised of $1.0 million and $6.7
million,  respectively,  in the three and nine months ended  September 30, 2006.
The Company received cash proceeds from stock options  exercised of $0.6 million
and $3.8 million, respectively, in the three and nine months ended September 30,
2005.

Stock options are generally awarded  annually.  The determination of the persons
to whom stock options will be awarded and the number of options  awarded will be
made prior to, and the exercise  price of the options will be set at the closing
price on, the second business Friday in January.

The  Financial   Accounting   Standards  Board  issued  Statement  of  Financial
Accounting  Standards No. 156,  "Accounting  for Servicing of Financial  Assets"
("FAS 156") during the first quarter of 2006.  FAS 156 permitted  companies that
service financial assets to elect to carry servicing rights at either fair value
or at the lower of amortized cost or fair value. Previously,  generally accepted
accounting  principles  required  servicing rights to be carried at the lower of
amortized  cost or fair value.  FAS 156 is effective for fiscal years that begin
after September

 35

15, 2006.  Early adoption is permitted as of the beginning of an entity's fiscal
year,  provided that the entity has not yet issued any financial  statements for
that year.

FAS 156 also  permitted  companies that service  financial  assets to reclassify
securities  designated  as an economic  hedge of the  servicing  rights from the
available  for sale  classification  to trading  without  tainting  management's
classification of the remaining available for sale securities portfolio.

Effective January 1, 2006, BOK Financial  designated all mortgage loan servicing
rights to be carried at fair value. An adjustment to initially  record servicing
rights at fair value increased retained earnings by $351 thousand, net of income
taxes. Additionally,  certain  specifically-identified  securities that had been
designated as economic hedges of the mortgage servicing rights were reclassified
from available for sale to trading. These securities are identified as "mortgage
trading  securities"  and are  separate  from the  Company's  normal  securities
trading  activities.  An adjustment to initially record these securities at fair
value increased retained earnings by $32 thousand, net of income taxes.

See Note 3 - Mortgage Banking Activities for additional  disclosures required by
FAS 156.

The  Financial   Accounting   Standards  Board  issued  Statement  of  Financial
Accounting  Standards  No.  157,  "Fair  Value  Measurements,"  ("FAS  157")  in
September  2006.  FAS 157  defines  fair  value,  establishes  a  framework  for
measuring  fair value in generally  accepted  accounting  principles and expands
disclosures  about fair value  measurements.  It does not expand the use of fair
value measurement to applications where it is not already required.

The  definition of fair value focuses on a  hypothetical  transaction  to either
sell an  asset  or  transfer  a  liability  at the  measurement  date  based  on
assumptions  that  market  participants  would  use  in  pricing  the  asset  or
liability,  including  assumptions about risk. A fair value measurement  assumes
that the transaction  occurs in the principal  market for the asset or liability
or, in the absence of a principal market,  the most advantageous  market for the
asset or liability.

FAS 157 also  nullifies a portion of EITF Issue No.  02-3,  "Issues  Involved in
Accounting  for  Derivative  Contracts  Held for Trading  Purposes and Contracts
Involved  in Energy  Trading  and Risk  Management  Activities."  The  nullified
portion  of EITF Issue No.  02-3  formed the  conceptual  basis for our  current
accounting policy for customer hedging programs.

FAS 157 is effective for financial  statements issued for fiscal years beginning
after November 15, 2007 and interim  periods within those fiscal years.  Earlier
application is encouraged,  provided that interim financial  statements have not
previously  been issued.  BOK Financial must adopt FAS 157 as of January 1, 2008
and may  choose to adopt FAS 157 as of January  1,  2007.  Management  is in the
process of determining the effect FAS 157 will have on the financial statements.

The  Financial   Accounting   Standards  Board  issued  Statement  of  Financial
Accounting Standards No. 158, "Employers' Accounting for Defined Benefit Pension
and Other Postretirement  Plans, an amendment of FASB Statements No. 87, 88, 106
and  132(R)"  ("FAS 158") in  September  2006.  FAS 158  requires  employers  to
recognize  the   overfunded  or   underfunded   status  of  a  defined   benefit
postretirement  plan as an asset or  liability  in its  statement  of  financial
position and to recognize  changes in the funded status in the year in which the
change occurs through  comprehensive income. The funded status of a benefit plan
is  defined as the  difference  between  the fair  value of plan  assets and the
benefit  obligation  measured as of the year-end statement of financial position
date.  Gains or losses and prior  service  costs or  credits  that have not been
recognized in net income as  components  of net periodic  benefit costs shall be
recognized  as a component of other  comprehensive  income,  net of tax. FAS 158
does not  change  existing  generally  accepted  accounting  principles  used to
determine net periodic benefit costs.

Recognition  of the funded status of a defined  benefit  postretirement  plan is
effective for  employers  with publicly  traded equity  securities,  such as BOK
Financial,  for fiscal  years ending  after  December  15,  2006.  Retrospective
application of FAS 158 is not permitted.

The effect of FAS 158 on BOK  Financial's  statement of financial  position will
not be know until the December 31, 2006 valuation is completed.  However, if FAS
158 had been effective at December 31, 2005, the prepaid  pension  expense asset
would have been reduced from $21.9 million to $1.3 million and accumulated other
comprehensive losses would have increased from $67.8 million to $80.4 million.

The Financial  Accounting  Standards  Board issued FASB  Interpretation  No. 48,
"Accounting  for  Uncertainty  in Income Taxes" ("FIN 48"), in June 2006. FIN 48
requires  that an uncertain  tax position  must be more likely than not of being
upheld upon audit by the taxing authority for the benefit to be recognized.  The
benefit of uncertain  tax positions  that do not meet this  criterion may not be
recognized. In addition, FIN 48 requires that the amount of tax benefit that may
be recognized for uncertain positions that meet the recognition  criterion shall
consider the amounts and  probabilities  of outcomes that could be realized upon
settlement.

FIN 48 is  effective  for  fiscal  years  beginning  after  December  15,  2006.
Management is in the process of determining the effect,  if any, the adoption of
FIN 48 will have on the financial statements.

(3) Mortgage Banking Activities

BOK Financial  implemented  Statement of Financial Accounting Standards No. 156,
"Accounting for Servicing of Financial  Assets" in the first quarter of 2006. An
initial   adjustment  of  the  mortgage   servicing  rights  to  fair  value  of
approximately $351 thousand,  net of income taxes, was recognized as an increase
to retained  earnings in the same period.  Also upon  implementation of FAS 156,
certain securities  designated as an economic hedge of mortgage servicing rights
were  transferred  from  the  available  for  sale  classification  to  trading.
Approximately $32 thousand was transferred from accumulated other  comprehensive
income to retained earnings for the net of tax effect of this reclassification.

At September 30, 2006, BOK Financial owned the rights to service 56,157 mortgage
loans with  outstanding  principal  balances  of $5.0  billion,  including  $471
million  serviced  for  affiliates.  The  weighted  average  interest  rate  and
remaining term was 6.13% and 277 months, respectively.

On March 31, 2006,  the Company paid  approximately  $6.8 million to acquire the
rights to service  approximately  $480 million of mortgage loans.  Substantially
all of these loans are to borrowers in our primary market areas.

For the three and nine months ended September 30, 2006, mortgage banking revenue
includes  servicing fee income of $4.0 million and $12.3 million,  respectively.
For the three and nine months ended September 30, 2005, mortgage banking revenue
includes servicing fee income of $4.0 million and $12.3 million, respectively.

(5) Employee Benefits

BOK Financial has sponsored a defined benefit Pension Plan for all employees who
satisfied  certain age and service  requirements.  During the fourth  quarter of
2005,  the  Company  modified  the  Pension  Plan to  curtail  benefit  accruals
effective  April 1, 2006.  During the nine months ended  September  30, 2006 and
2005, net periodic pension cost was approximately $1.8 million and $4.8 million,
respectively.

During the second quarter of 2006,  the Company made Pension Plan  contributions
totaling $2.8 million,  which funded the remaining maximum contribution for 2005
permitted under applicable  regulations.  The Company made no other Pension Plan
contributions during the nine months ended September 30, 2006.

Management  has been advised that no minimum  contribution  will be required for
2006. Due to the curtailment,  the maximum  allowable  contribution for 2006 has
not yet been determined.

(6) Shareholders' Equity

On  October  31,  2006,  the Board of  Directors  of BOK  Financial  Corporation

(1) Excluding financial instruments gains/(losses).

(9)  Contingent Liabilities

On October 10, 2006, the Securities and Exchange  Commission (the "SEC") started
a special  examination of AXIA Investment  Advisers,  Inc.  ("AXIA").  AXIA is a
wholly-owned subsidiary of the Bank of Oklahoma, N.A. and the investment adviser
to the American  Performance Funds (the "Funds"),  a family of mutual funds. The
examination is focused on the BISYS Fund Services Ohio, Inc. (`BISYS") marketing
assistance agreements with AXIA that were terminated in 2004. In September 2006,
BISYS settled the SEC's two-year  investigation  of it by consenting to an order
in which the SEC  determined  that BISYS had  "willfully  aided and  abetted and
caused" (1) the investment  advisors to 27 different families of mutual funds to
violate  provisions  of the  Investment  Advisors  Act  of  1940  that  prohibit
fraudulent  conduct;  (2) the  investment  advisors  to the 27 fund  families to
violate  provisions of the Investment  Company Act of 1940 (the "1940 Act") that
prohibit the making of any untrue statement of a material fact in a registration
statement filed by the mutual fund with the SEC; and (3) the 27 fund families to
violate  provision of the 1940 Act that require the  disclosure and inclusion of
all  distribution  arrangements  and expenses in the fund's 12b-1 fee plan. AXIA
was one of the 27 advisers,  and the Funds one of the mutual fund  families,  to
which the SEC  referred.  AXIA is not bound by the SEC BISYS Order and disagrees
with its findings as they relate to AXIA. Although the SEC's examination of AXIA
has just begun,  the Company does not expect the  examination  or any action the
SEC may take based upon it to have a material adverse effect on the Company.

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

(10) Financial Instruments with Off-Balance Sheet Risk

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

As of September 30, 2006, outstanding  commitments and letters of credit were as
follows (in thousands):

                                               Sept. 30,
                                                2006
                                            --------------
Commitments to extend credit                $  5,027,486
Standby letters of credit                        472,853
Commercial letters of credit                      16,493
Commitments to purchase securities                35,012

     the  Company's  board of  directors on February 24, 1998 and amended on May

     800,000  shares of its common stock.  As of March 31, 2005, the Company had

     to two million  shares of the Company's  common stock.  As of September 30,
     2006, the Company had repurchased 271,177 shares under the new plan.
