MANAGEMENT'S ASSESSMENT OF OPERATIONS AND FINANCIAL CONDITION

Assessment of Operations

Summary of Performance

BOK Financial Corporation ("BOK Financial") recorded net income of $22.7 million
or $0.41 per  diluted  common  share for the third  quarter of 1999  compared to
$20.0  million or $0.36 per diluted  common share for the third quarter of 1998.
Returns on average  assets were 1.15% for the third  quarter of 1999 compared to
1.34% for the third quarter of 1998. The decrease in return on average assets is
due to the growth in average assets over the past twelve months,  including $926
million due to  acquisitions.  Returns on average equity,  including $53 million
decrease in unrealized  gain on securities  available for sale,  were 16.81% and
16.21%, for the third quarter of 1999 and 1998, respectively.

Net interest revenue for the third quarter of 1999 increased by $13.5 million or
28% while fees and commissions  revenue grew by $2.4 million or 6%. This revenue
growth was  largely  offset by a $12.6  million  or 22%  increase  in  operating
expenses,  which included a $2.2 million  increase in amortization of intangible
assets.

Operating  results for the third  quarter of 1999 include  Bank of  Albuquerque,
which was acquired in the fourth quarter of 1998 and  Mid-Cities  National Bank,
Canyon Creek  National  Bank and Swiss Avenue State Bank which were  acquired in
the second quarter of 1999.

Year to date net income and earnings per diluted common share were $66.0 million
or  $1.18,   respectively   for  1999   compared  to  $59.2  million  or  $1.06,
respectively,  for the same period in 1998. Returns on average assets and equity
were 1.19% and  16.40%,  respectively,  for 1999  compared to returns on average
assets and equity of 1.37% and 16.73%, respectively, for 1998.

All per share data have been  restated for a 3 percent  stock  dividend that was
announced on September 28, 1999 and paid in October, 1999.



Tangible Operating Results

Since  inception,  BOK Financial has completed  several  acquisitions  that were
accounted  for under the purchase  method of  accounting.  The  purchase  method
results in the recording of goodwill and other  identifiable  intangible  assets
that are amortized as non-cash  charges in future years into operating  expense.
Operating  results  excluding the impact of the amortization of these intangible
assets are summarized below:

of $914 million. Interest bearing deposits increased $949 million. The growth in
average earning assets and interest  bearing  liabilities  included $811 million
and $759 million,  respectively,  due to  acquisitions  in the fourth quarter of

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

Year to date, net interest revenue  increased by $31.7 million compared to 1998.
Excluding  the  non-recurring  collection  of foregone  interest  in 1998,  this
represented  a 23%  increase  in net  interest  revenue due to growth in earning
assets.

Net  interest  margin,  the ratio of net  interest  revenue to  average  earning
assets,  was 3.66% for the third quarter of 1999 compared to 3.72% for the third
quarter of 1998 and 3.60% for the second quarter of 1999.

Since  inception,  BOK Financial has followed a strategy of fully  utilizing its
capital  resources  by  borrowing  funds in the  capital  markets to  supplement
deposit  growth in order to fund increased  investments in securities.  Although
this strategy  typically results in a net interest margin that falls below those
normally  seen in the  commercial  banking  industry,  it provides  positive net
interest revenue.  Management estimates that for the third quarter of 1999, this
strategy resulted in a 71 basis point decrease in net interest margin.  However,
this strategy  contributed $3.7 million to net interest  revenue.  As more fully
discussed in the Market Risk section,  management  employs various techniques to
control,  within  established  parameters,  the interest rate and liquidity risk
inherent in this strategy.

Other Operating Revenue

Other  operating  revenue for the third quarter of 1999  increased  $1.4 million
compared  to the same  quarter of 1998.  Total fees and  commissions,  which are
included in other operating  revenue,  increased $2.4 million or 6%. Transaction
card revenue increased $1.8 million or 27% over the third quarter of 1998 due to
a  greater  volume  of  transactions  processed.  Service  charges  on  deposits
increased  $2.4  million or 29%,  including  $1.5  million due to  acquisitions.
Leasing  revenue  decreased  $1.2  million  due to the  sale of BOK  Financial's
interests  in four  leasing  partnerships  during  the  second  quarter of 1999.
Brokerage  and trading  revenue  decreased  $872  thousand  due  primarily  to a
revaluation of the residual interest in a pool of automobile loans that was sold
in the first quarter of 1999.  Actual  repayments of the loans have exceeded the
initial  estimates.  The  accelerated  repayments  has  reduced the value of the
residual interest.

Year to date, other operating  revenue increased $12.1 million or 9% compared to
1998. Total fees and commissions increased $15.1 million or 12% due primarily to
increases in transaction  card revenue and service charges on deposit  accounts.
Additionally,  other  revenue  for the nine  months  ended  September  30,  1999
included $4.3 million for  underwriting  and private  placement fees compared to
$348 thousand for the same period of 1998.



Other Operating Expenses

Operating  expenses for the third quarter of 1999 increased $12.6 million or 22%
compared  to the third  quarter  of 1998.  The third  quarter  of 1999  included
operating  expenses of $9.3 million for acquired banks that were not included in
the third quarter of 1998. The discussion  following  Table 4 of other operating
expenses excludes these charges from 1999 to improve comparability.

Personnel  costs  increased  $3.8  million  due to  increased  staffing,  normal
compensation  increases  and  increased  incentive  compensation.  Staffing on a
full-time  equivalent  ("FTE") basis  increased by 198  employees  while average
compensation  per FTE  increased  by 2%.  Incentive  compensation,  which varies
directly with revenue  increased  $950 thousand to $3.5 million for the quarter.
The  increase  in  incentive  compensation  was due to  growth in  revenue  over
pre-determined  targets  and growth in the number of business  units  covered by
incentive plans.  Occupancy,  equipment and data processing costs increased $2.5
million or 23%,  due  primarily  to an  increase  in data  processing  costs.  A
significant  portion of BOK  Financial's  data processing is outsourced to third
parties.  Therefore, data processing costs are directly related to the volume of
transactions processed.

Operating  expenses  through  September  30, 1999 were $35 million or 20% higher
than operating expenses for the first nine months of 1998. Excluding significant
or  non-recurring  items and the  effect  of  acquisitions,  operating  expenses
increased $16.4 million or 10% due primarily to higher  personnel costs and data
processing expenses.

Consumer banking  contributed $3.2 million or 14% of consolidated net income for
the third  quarter of 1999 compared to $2.4 million or 24% of  consolidated  net
income for the third quarter of 1998. Total revenue, which consists primarily of
intercompany  credit for funds provided to other  divisions of BOK Financial and
fees generated by various services, were unchanged compared to the third quarter
of 1998. Operating expenses decreased $977 thousand for the same period.

Mortgage Banking

Mortgage banking  contributed $466 thousand or 2% of consolidated net income for
the third  quarter of 1999  compared to $1.7 million or 8% for the third quarter
of 1998.  Total  revenue  decreased  $2.4  million.  Mortgage  loan  origination
activity has decreased since last year due to higher  interest rates,  resulting
in lower gains on secondary  marketing  activity.  Revenue from mortgage banking
activities  was also  reduced by  internal  funding  costs  associated  with the
deferred hedging losses.

Capitalized  mortgage  servicing  rights totaled $106.5 million at September 30,
1999  compared to $107.0  million at June 30, 1999 and $69.2 million at December
31, 1998.  The increase in  capitalized  servicing  rights was due  primarily to
$28.5 million in hedging  losses  realized since December 31, 1998. At September
30, 1999,  realized  hedging  losses  totaled $7.4 million,  net of  accumulated
amortization,  while unrealized  losses on open hedging  positions  totaled $347
thousand.

YEAR 2000 CONSIDERATIONS

The Year 2000  issue,  in  general,  is the result of  computer  programs  being
written using two digits  rather than four to define the  applicable  year.  Any
computer  programs that have date sensitive  software may recognize a date using
"00" as the year 1900 rather than the year 2000.  This could  result in a system
failure or miscalculations  causing  disruptions of operations,  including among
other  things,  a temporary  inability to process  transactions  or to engage in
similar normal business activities.

BOK  Financial's  Year 2000  efforts  are under the  direction  of the Year 2000
Oversight Committee,  comprised of various members of executive  management,  as
well as a Year  2000  Project  Team,  which  includes  representatives  from BOK
Financial's major business units. Both groups meet on a regular basis to monitor
and discuss continuing Year 2000 developments. The Board of Directors recognizes
the importance of and supports these Year 2000 initiatives.

The  Federal  Financial  Institution   Examination  Council  ("FFIEC")  provides
regulatory  guidance on BOK Financial's and other financial  institutions'  Year
2000 compliance.  These guidelines covered system testing,  business  resumption
planning,  cash  reserve  considerations,  as well as  guidance  for  monitoring
systems  during the weekend of December  31st.  BOK Financial  has  successfully
completed all requirements.

FFIEC guidelines also required financial  institutions to substantially complete
the four  phases  of the Year  2000  business  resumption  contingency  planning
process no later than June 30, 1999. BOK  Financial's  Year 2000 Project Team is
focused on  preparation  for the Year 2000 event.  Plans have been  finalized to
address  certain  situations  that may arise as a result of internal or external
disruptions.  These plans have been simulated or otherwise  validated during the
third  quarter  of  1999.  System  change  control  policies  require  that  new
enhancements or initiatives within the company or at our outsourced providers be
tested  for  Year  2000  compliance  prior  to  introduction  to our  processing
environment. This policy includes severe limitations on all changes from October
1, 1999 through  February 29, 2000.  Finally,  plans have been developed to have
key resources  available  throughout  all high risk  processing  periods  during
December,  1999 and January and February,  2000. Additional costs to prepare for
Year 2000 are not expected to be significant.

 BOK  Financial has also  communicated  with large  customers to determine  what
steps they have  undertaken  to ensure  they are  prepared  for Year 2000.  This
effort has enabled  BOK  Financial  to adopt  contingency  plans  related to the
possible  effects of the Year 2000 issue on the  credit  risk of its  borrowers,
cash flow disruptions of its funds providers,  and its overall  liquidity needs.
BOK Financial has included the potential  effect of Year 2000 on the credit risk
of its borrowers in determining the adequacy of its loan loss reserve.

The foregoing forward-looking statements,  including the costs of addressing the
Year 2000 issue,  reflect  management's  current  assessment  and estimates with
respect to BOK Financial's  Year 2000 compliance  effort.  Various factors could
cause actual plans and results to differ  materially from those  contemplated by
such assessments,  estimates and forward-looking  statements,  many of which are
beyond the control of BOK Financial.  Some of these factors include, but are not
limited to, third party  modification  plans,  availability of technological and
monetary   resources,   representations   by  vendors   and   counter   parties,
technological advances,  economic  considerations and consumer perceptions.  BOK
Financial's  Year  2000  compliance  program  is an  ongoing  process  involving
continual   evaluation  and  may  be  subject  to  change  in  response  to  new
developments.




Assessment of Financial Condition

The aggregate  loan  portfolio at September 30, 1999  increased  $283 million to
$4.4 billion during the third quarter of 1999.  Commercial  loans increased $205
million and commercial real estate loans increased $58 million, respectively.

While BOK Financial  continues to increase  geographic  diversification  through
expansion in the Dallas,  Texas and  Albuquerque,  New Mexico areas,  geographic
concentration  subjects the loan portfolio to the general economic conditions in
Oklahoma.  Notable loan  concentrations by the primary industry of the borrowers
are presented in Table 10.  Agriculture  includes loans totaling $141 million to
the cattle industry. Services include loans totaling $160 million to nursing and
medical  facilities  and $113  million to the hotel  industry.  Commercial  real
estate loans are secured  primarily by  properties in the Tulsa or Oklahoma City
metropolitan  areas.  The major components of other real estate loans are office
buildings, $174 million and retail facilities, $158 million.



SUMMARY OF LOAN LOSS EXPERIENCE

The reserve for loans losses,  which is available to absorb  losses  inherent in
the loan  portfolio,  totaled $75 million at September 30, 1999,  $73 million at
June 30, 1999 and $66 million at December 31, 1998. This represents 1.73%, 1.80%
and 1.86% of total loans,  excluding loans held for sale, at September 30, 1999,
June 30, 1999,  and December  31, 1998,  respectively.  Losses on loans held for
sale, principally mortgage loans accumulated for placement in securitized pools,
are charged to earnings  through  adjustments  in carrying value to the lower of
cost or market value in  accordance  with  accounting  standards  applicable  to
mortgage  banking.  Table 11  presents  statistical  information  regarding  the
reserve for loan losses for the past five quarters.

The adequacy of the reserve for loan losses is assessed by management based upon
an ongoing quarterly evaluation of the probable estimated losses inherent in the
portfolio.  A consistent  methodology has been developed that includes  reserves
assigned to specific  criticized  loans,  general reserves that are based upon a
statistical  migration  analysis  for each  category of loans,  and  unallocated
reserves that are based upon an analysis of current  economic  conditions,  loan
concentrations,  portfolio growth,  and other relevant  factors.  An independent
Credit  Administration  department is responsible for performing this evaluation
for all of BOK  Financial's  subsidiaries  to  ensure  that the  methodology  is
applied consistently.

All   significant   criticized   loans  are  reviewed   quarterly  with  written
documentation.  Specific  reserves for  impairment  are determined in accordance
with  generally  accepted  accounting  principles  and  appropriate   regulatory
standards.  At September 30, 1999,  specific  impairment  reserves  totaled $1.9
million.






The adequacy of general loan loss  reserves is determined  primarily  through an
internally developed migration analysis model.  Management uses an eight-quarter
aggregate  accumulation of net loan losses as the basis for this model.  Greater
emphasis is placed on net loan losses in the more recent periods.  This model is
used to assign  general  loan loss  reserves  to  commercial  loans and  leases,
residential  mortgage loans and consumer loans. All loans, leases and letters of
credit are allocated a migration  factor by this model.  Management can override
the general  allocation only by utilizing a specific  allocation that is greater
than the general allocation.

A nonspecific  allowance  for loan losses is  maintained  for risks beyond those
factors  specific to a  particular  loan or those  identified  by the  migration
analysis.  These factors  include trends in general  economic  conditions in BOK
Financial's  primary  lending areas,  duration of the business  cycle,  specific
conditions in  industries  where BOK  Financial  has a  concentration  of loans,
overall growth in the loan portfolio, bank regulatory examination results, error
potential in either the migration  analysis model or in the underlying data, and
other relevant factors.  A range of potential losses is then determined for each
factor identified. At September 30, 1999, the loss potential ranges for the more
significant factors are:

Concentration of large loans -   $1.1 million to $2.2 million
Loan  portfolio  growth and  expansion  into new markets - $1.2  million to $2.3
million

A provision for loan losses is charged against earnings in amounts  necessary to
maintain an adequate  allowance  for loan  losses.  These  provisions  were $2.1
million for the third  quarter of 1999  compared to $2.5  million for the second
quarter of 1999 and $4.1 million for the third quarter of 1998.

NON-PERFORMING ASSETS

Information regarding non-performing assets, which were $22 million at September
30,  1999,  $25 million at June 30, 1999 and $19 million at December 31, 1998 is
presented  in Table  12.  Non-performing  loans  include  non-accrual  loans and
renegotiated loans, and exclude loans 90 days past due.

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  performing  in
accordance  with  the  original  terms  of the  loan  agreements  and no loss of
principal  or  interest  is  anticipated,  such  loans are not  included  in the
Non-performing   Assets  totals.  These  loans  are  assigned  to  various  risk
categories  in order to focus  management's  attention  on the loans with higher
risk of loss. At September 30, 1999, loans totaling $95 million were assigned by
management to the substandard  risk category and loans totaling $77 million were
assigned to the special  mention risk category,  compared to $79 million and $54
million,  respectively,  at June 30, 1999.  Management expects that the level of
loans  assigned to these risk  categories  will  moderate  over the next nine to
twelve months as  improvements in the energy and cattle sectors begin to show in
the operating results of BOK Financial's borrowers.
This expectation depends upon continued stability in the overall economy.

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 rates,  commodity
prices, or equity prices.  Additionally,  the financial  instruments  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 portfolio of assets held for purposes  other than
trading  and  trading  assets.  The  effect of other  changes,  such as  foreign
exchange rates, commodity prices or equity prices, do not pose a material market
risk to BOK Financial.  The  responsibility  for managing market risk rests with
the Asset/Liability Committee which operates under policy guidelines established
by the Board of  Directors.  The negative  acceptable  variation in net interest
revenue  and  economic  value of equity  due to a 200 basis  point  increase  or
decrease in interest rates is generally  limited by these guidelines to +/- 10%.
These  guidelines  also  establish  maximum  levels for  short-term  borrowings,
short-term  assets,  and public and brokered  deposits,  and  establish  minimum
levels for unpledged assets, among other things.
Compliance with these guidelines is reviewed monthly.



Interest Rate Risk Management (Other than Trading)

BOK Financial performs a sensitivity  analysis to identify more dynamic interest
rate risk  exposures,  including  embedded  option  positions,  on net  interest
revenue,  net income and economic value of equity. A simulation model is used to
estimate  the effect of changes in interest  rates over the next  twelve  months
based on three interest rate scenarios.  These are a "most likely" rate scenario
and two "shock  test"  scenarios,  the first  assuming a sustained  parallel 200
basis point increase and the third a sustained parallel 200 basis point decrease
in interest  rates.  An independent  source is used to determine the most likely
interest  rates  for the  next  year.  BOK  Financial's  primary  interest  rate
exposures  include  the  Federal  Reserve  Bank's  discount  rate which  affects
short-term borrowings,  the prime lending rate and the London InterBank Offering
Rate ("LIBOR") which are the basis for much of the  variable-rate  loan pricing,
the 30-year  mortgage  rate which  directly  affects the  prepayment  speeds for
mortgage-backed  securities and mortgage  servicing rights, and the 10-year U.S.
Treasury  rate  which  affects  the  value  of the  mortgage  servicing  hedges.
Derivative  financial  instruments  and  other  financial  instruments  used for
purposes  other than  trading are  included  in this  simulation.  In  addition,
sensitivity of fee income to market interest rate levels,  such as those related
to cash  management  services and  mortgage  servicing,  is included.  The model
incorporates  management's  assumptions  regarding the level of interest rate or
balance  changes  on   indeterminable   maturity   deposits  (demand   deposits,
interest-bearing transaction accounts and savings accounts) for a given level of
market rate changes.  The assumptions have been developed  through a combination
of historical analysis and future expected pricing behavior. Interest rate swaps
on all  products  are  included  to the extent  that they are  effective  in the
12-month  simulation  period.  Additionally,  changes in prepayment  behavior of
mortgage-backed securities, residential mortgage loans and mortgage servicing in
each rate environment are captured using industry estimates of prepayment speeds
for various  coupon  segments of the portfolio.  Finally,  the impact of planned
growth and new business  activities is factored into the  simulation  model.  At
September 30, 1999 and 1998, this modeling  indicated  interest rate sensitivity
as follows:

The estimated changes in interest rates on net interest revenue or net income is
not  projected  to be  significant  within  the +/- 200  basis  point  range  of
assumptions.  However,  this modeling  indicated  that under the 200 basis point
increase  scenario,  BOK Financial's  economic value of equity would decrease by
$43.7 million due primarily to the effect of rising  interest rates on the value
of the securities portfolio.



BOK Financial  hedges its loss exposure  from the  prepayment of mortgage  loans
that it services  through  the use of futures  contracts,  call  options and put
options. These derivatives are based upon 10-year U.S. Treasury securities.  The
changes in value of these derivatives have a highly correlated, inverse relation
to  changes  in  value of the  mortgage  servicing  rights.  The  interest  rate
sensitivity of the mortgage servicing portfolio and the related hedge is modeled
over a range of + or - 50 basis  points.  At  September  30,  1999,  the pre-tax
results of this modeling are as follows:

                                    50 bp increase       50 bp decrease
                                   -----------------    ------------------

                                   =================    ==================

The  simulations  used to manage  market risk are based on numerous  assumptions
regarding  the effect 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 and changes in market conditions and management  strategies,  among
other factors.

BOK Financial uses interest rate swaps, a form of off-balance  sheet  derivative
product, in managing its interest rate sensitivity. These products are generally
used to more closely match interest paid on certain  long-term  certificates  of
deposit and  subordinated  debt with earning assets.  BOK Financial  agrees with
other  parties to  exchange,  at specified  intervals,  the  difference  between
fixed-rate  and  floating-rate  interest  amounts  calculated by reference to an
agreed-upon  notional amount.  For the third quarter of 1999,  income from these
swaps  exceeded the cost of the swaps by $362  thousand.  Credit risk from these
swaps is closely monitored and counterparties to these contracts are selected on
the basis of their credit worthiness,  among other factors.  Derivative products
are not used for speculative purposes.

Trading Activities

BOK Financial enters into trading account 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 other
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 through Bank of Oklahoma,  N.A. and BOSC, Inc. 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  positions.  The Risk Management
Department  monitors trading activity daily and reports to senior management and
the Risk  Overssight  and  Audit  Committee  of the  Board of  Directors  on any
exceptions to trading position limits and risk management policy.

BOK  Financial  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.  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 nominal  aggregate  trading  positions to
$360 million and the VAR to $6.5  million.  At September  30, 1999,  the nominal
aggregate trading positions was $15 million, the VAR was $539 thousand.

Financial  institutions are considered to be "well capitalized"  pursuant to the
Federal Deposit Insurance Corporation Improvement Act of 1991 if their Leverage,
Tier 1 and Total Capital ratios are at least 5%, 6%, and 10%, respectively.  BOK
Financial and its subsidiary banks continue to exceed the regulatory  definition
of well  capitalized.  However,  BOK  Financial's  capital  ratios have declined
compared  to the  third  quarter  of 1998  due to its  acquisition  program  and
continued  asset  growth.  While  management  projects  capital  to grow and the
capital ratios to increase over time,  future asset growth and  acquisitions may
be constrained by capital limitations.

BOK Financial  had borrowing  lines from other  commercial  banks  totaling $105
million  which have been  renegotiated  into a $125  million  syndicated  senior
facility with a three year maturity,  interest based on LIBOR + 75 basis points.
The debt  facility  includes  covenants on capital  adequacy,  asset quality and
indebtedness that are generally consistent with regulatory guidelines.
