RIGHT VALUES
LETTER FROM MANAGEMENT

     Right values.  Right  strategies.  Right results.  The theme of this year's
annual  report  to  shareholders  seems  fitting  as we look  back  at our  past
achievements and ahead to anticipated  successes on behalf of our  stockholders,
customers and employees.  Since the company's inception 12 years ago, our aim at
BOK Financial  Corporation has been to produce consistently superior returns for
investors.  To do this we have utilized  strategies that promote growth at home,
expansion into high-growth markets, superior service to middle market commercial
clients and a diverse revenue base to help us succeed through economic cycles.

     At no time in the  company's  history has the prudence of our approach been
more evident than in 2002,  when we reported  record net income of $150 million,
an  increase  of 29  percent  over the  previous  year.  Yet,  behind all of our
strategies and  accomplishments  are core beliefs that govern what we do and how
we think, year in and year out. Simply put, our values dictate that we do things
right.

     We take a discreet,  forthright  approach in applying  accounting rules and
standards to ensure our financial  reports  accurately and fairly  represent the
financial  condition  of the  company.  We  manage  our  resources  and base our
decisions on sound ethical and legal  principles.  Our outlook is evident in the
caliber  of  our  board  of  directors,  the  experience  and  expertise  of our
management  team and the talent and  dedication of front-line  employees who are
ultimately responsible for our achievements.

     The  BOK  Financial  board  of  directors   consists  of  veteran  business
professionals and corporate and community leaders whose integrity, expertise and
business acumen set the tone for our success. Our managers demonstrate seasoned,
insightful judgment to devise and execute progressive strategies. Our employees'
dedication to quality and innovation is second to none.

     Our values will carry us forward as we continue  to  implement  far-sighted
strategies that produce solid performance across-the-board--even during economic
slowdowns. Despite the soft economy, our diluted earnings per share in 2002 rose
27  percent,  to $2.48.  Total  loans grew 10 percent  and  deposits 18 percent,
contributing to growth in net interest revenue of 12 percent.  Altogether, total
revenue  rose  18  percent.  Non-interest  revenue  from  fees  and  commissions
comprised 41 percent of revenue when  excluding  gains from sales of  securities
and  derivatives.  That  puts  our  diversification  of  revenue  well  ahead of
comparable banking companies.

     Total assets increased 10 percent to $12.2 billion,  and loans rose to $6.9
billion,  with the company  experiencing growth in commercial loans,  commercial
real estate loans and residential  mortgage loans.  Our loan growth was aided by
the  acquisition  of Bank of  Tanglewood  in Houston and the opening of a Denver
loan  production  office,  which  enhanced the portfolio by $132 million and $65
million,  respectively.  Deposits  were $8.1  billion at  year-end,  and deposit
growth  enabled  us to fund  asset  growth  and  reduce  borrowed  funds by $198
million.

     In the  securities  portfolio,  our strategy of investing  for total return
served us well in 2002.  Gains  from the  sales of  securities  and  derivatives
generated revenue of $65 million, up $38 million from 2001. Total gains included
$26 million from a hedge program designed to offset the volatility in the market
value of our mortgage  servicing rights (MSR). The MSR impairment and associated
amortization  costs  have  increased  because  of the high  volume  of  mortgage
refinancing during times of record low interest rates.

     BOK Financial  adopted a new accounting  standard in 2002 that discontinued
amortization  of goodwill,  but even if the standard had been  effective  during
2001,  income growth in 2002 would have been 22 percent over the previous  year.
When the MSR accounting  charge and the sales of securities and derivatives from
both 2001 and 2002 are excluded,  the company  produced 18 percent growth in net
income.

     Asset quality continued to be evident in 2002 as key measures remained well
ahead of peer banks with  assets from $7 billion to $20  billion.  Nonperforming
assets to period-end loans remained relatively steady at 0.84 percent while loan
loss reserves were 1.72 percent of period-end loans,  compared with 1.59 percent
for our peers. Net charge-offs to average loans declined to 0.33 percent for the
year from 0.35 percent while the average for our peers was 0.57 percent.

     This year, we are committed to achieving more success with the expansion in
Houston,  where we also opened new locations  over the past year. The success of
our loan  production  office in Denver is providing us with a solid platform for
exploring a full  service  banking  presence in that  fast-growing  metropolitan
area.

     We remain  confident that our sound  strategies  backed by the right values
will  continue to produce  solid  results.  Through it all, we will  continue to
value our people, our customers and the communities we serve as we carry out our
mission of generating optimal long-term returns for our shareholders.

RIGHT STRATEGIES
ENHANCE OKLAHOMA LEADERSHIP

     Over the past five years, south Tulsa and the adjacent suburb of Jenks have
experienced a surge of residential  construction and commercial development.  To
serve the bustling  area,  Branch  Manager Cathy Wilson and her staff opened the
doors in October on a new Bank of Oklahoma  location  that brings  service  even
closer to our customers.  In just over two months,  new deposits and loans there
exceeded targets by 96 percent and 162 percent,  respectively. A new branch in a
growing  area is but one example of our resolve to remain the  dominant  bank in
our original market.

     During the past decade,  we emerged as the clear financial  services leader
in  Oklahoma  while our  chief  rivals  sold to large  out-of-state  banks  with
distant, impersonal customer service. We offered nationally competitive products
with the  personal  touch of a community  bank,  an approach  that  continues to
appeal to  businesses  and  consumers.  As a result of our  commitment,  Bank of
Oklahoma  has 12 percent of the  state's  total  deposits  and an  estimated  27
percent of commercial loans,  according to SNL DataSource.  That compares with 6
percent  of  deposits  and  7  percent  of  commercial  loans  for  our  nearest
competitors.  In Tulsa  County  alone,  we have an  estimated  50 percent of the
commercial lending market. In Oklahoma County, which includes Oklahoma City, our
commercial lending market share has grown to almost 24 percent.

Pictures of Cathy Wilson (Branch Manager, Tulsa) and Sheryl Eastwood (Manager of
Mortgage Origination, Oklahoma City) shown here.

See #1 Market Share data in Appendix A.

     We have 68  full-service  locations  statewide,  including  community banks
serving Bartlesville,  Enid, Eufaula, Grove, McAlester, Muskogee, Newkirk, Ponca
City and Sand  Springs.  But we refuse to take our  Oklahoma  lead for  granted.
Growth in middle market  commercial  and small business  lending  remained major
priorities  in 2002,  and we were able to grow total loans 7 percent,  despite a
slowdown  in the overall  market.  We  introduced  check cards with logos of the
University of Oklahoma and Oklahoma State University,  which remain popular with
customers.  Our customers  also enjoyed our new Overdraft  Privilege  service on
checking accounts.

     In 2002, record low interest rates accelerated loan growth at BOk Mortgage,
which does business in six states.  The company remains the leading  provider of
residential  mortgages in Oklahoma,  accounting for a major portion of statewide
originations.  In Tulsa  County,  the mortgage  company  enjoyed an estimated 22
percent share of all loan fundings among the Top 20 lenders, according to public
filings.  And in 2002 we continued to make strides in Oklahoma City,  where Vice
President  Sheryl  Eastwood  heads up a team of lenders  dedicated  to expanding
market share already estimated at 20 percent.

     Bank of Oklahoma  will  continue to offer  convenience,  a broader array of
products and services and small business and commercial  lending  initiatives to
fuel our growth and enhance our leadership.

RIGHT STRATEGIES
EXPAND IN ATTRACTIVE MARKETS

     In 2002, CEO Rich Jochetz and his  shareholders  at Bank of Tanglewood were
at a crossroads after six years of rapid growth into a $236 million  institution
catering to affluent  Houstonians  and their  businesses.  The bank could invest
millions  to  introduce  additional  services  and  open new  locations  to keep
pace--or find the right merger partner.  BOK Financial persuaded this successful
group of bankers  to take the  latter  course,  and the  acquisition  of Bank of
Tanglewood and its merger with Bank of Texas marked the latest  milestone in our
strategic expansion into high-growth metropolitan areas in neighboring states.

     We formed Bank of Texas in 1997 from  acquisitions in the Dallas-Fort Worth
Metroplex  and  launched  Bank  of  Texas-Houston  with  the  purchase  of  CNBT
Bancshares  in 2001.  Our  efforts  have  allowed  us to  compete  in two of the
country's most vibrant markets.  Both Dallas-Fort  Worth and Greater Houston had
more than 25 percent  population  growth during the 1990s and now have more than
11 million  residents  combined.  Median  incomes  are well  above the  national
average.

     We have  acquired  established,  well-managed  institutions,  then formed a
solid foundation for new growth by combining  community banking expertise with a
desirable local brand name and our strengths in middle market lending, trust and
private financial services.

(President,  Bank of Texas - Houston),  and Tom Foncannon (SVP & Manger,  Denver
Loan Production Office) shown here.

See Total Deposits Per Market data in Appendix A.

See Companies With Revenue $10-750 million in Appendix A.

     To run our  operations,  we recruited  and retained  talented,  experienced
bankers  with  strong  local  roots.   Jochetz  is  now  president  of  Bank  of
Texas-Houston  and, Ralph Williams,  formerly of CNBT, is the Houston  chairman.
Both work in concert with Barry Kelly,  executive  vice president over corporate
banking in the Houston market.

     Growth didn't stop with acquisitions. While we have acquired assets of $1.5
billion in Texas,  we have added  another  $900  million in new  business  as we
successfully  marketed our products and  services.  We added  locations in 2002,
including one in the Dallas suburb of Plano and two in Greater Houston.  Bank of
Texas has 28 locations, including 12 in the Houston area.

     We continue to look for new opportunities in other markets.  We formed Bank
of Albuquerque in 1998 and continue to experience healthy growth in a metro area
that accounts for almost half of New Mexico's  economic output. In 2002, Bank of
Oklahoma  opened a loan  production  office  in Denver  headed  by  Senior  Vice
President Tom Foncannon.  At year-end,  we had $65 million in loans outstanding,
and by January 31, that had grown to more than $100 million.  Greater success is
expected as we forge ahead with plans to  establish a full  banking  presence in
the Denver area, the economic and business hub of Colorado and home to more than
2 million residents.

RIGHT STRATEGIES
FILL MIDDLE MARKET VACUUM

     Bank of  Texas-Dallas  President  Tom Swiley keeps his eye on a potentially
huge prize in the Dallas-Fort  Worth  Metroplex--more  than 3,000 companies with
revenue from $10 million to $750  million,  according to Dun &  Bradstreet.  The
bank  focuses on about 400 of those,  but Swiley and Bank of Texas  Chairman and
CEO Fred  Ball know  there's  plenty of new  business  to be won as more  middle
market  companies  feel  alienated  from  merging  mega  banks.  Bank  of  Texas
specializes in exceptional  customer service that gives business executives easy
access to account officers and the bank's senior management.

     Big bank  consolidation  over the past decade created a void in the crucial
middle  market,  where  entrepreneurial  companies  are in  need  of  responsive
bankers.  Utilizing the skills we honed financing emerging companies in Oklahoma
and Arkansas, BOK Financial implemented a strategy of catering to the commercial
middle  market as we formed new banks and expanded into  high-growth  markets in
neighboring states.

     In Dallas-Fort Worth and Greater Houston, the commercial lending outlook is
especially promising.  Thousands of companies in the Dallas-Fort Worth Metroplex
contribute to a gross domestic  product of more than $250 billion,  19th largest
compared with the world's  nations.  Greater  Houston's GDP is approaching  $245
billion and its middle market  companies  seek personal  banking  relationships.
Despite an economic slowdown in 2002, commercial loan growth attributable to our
Texas operations rose more than 11 percent.

& CEO, Bank of Texas), Paul Sowards (President,  Bank of Albuquerque),  and Greg
Symons (Chairman & CEO, Bank of Albuquerque) shown here.

See Loans - 3-year Compound Annual Growth Rate data in Appendix A.

See Deposits - 3-year Compound Annual Growth Rate data in Appendix A.

     In 2002,  we made big strides in New Mexico,  where there are  considerable
opportunities  in small business and middle market lending.  Bank of Albuquerque
is competing  successfully against the country's largest banks by attracting top
banking talent and new customer relationships.  Commercial loans grew 31 percent
in 2002,  with commercial real estate loans up 10 percent and total loans rising
17 percent,  to $524  million.  Bank of  Albuquerque  was formed in 1998 when we
purchased 17 branch locations from Bank of America with combined loans valued at
$172 million.  In addition to establishing a full-service  location in Santa Fe,
the bank since its  founding has  recruited  the top  commercial  bankers in the
market  from  larger  competitors,  forming a premier  lending  group  under the
direction of Chairman and CEO Greg Symons and bank President Paul Sowards.

     We continue to establish  new  relationships  in Northwest  Arkansas and in
Oklahoma,  where we are  already the  dominant  force in the  commercial  middle
market.  We are also attracting  additional  customers by  cross-selling  loans,
treasury services and international banking. Especially appealing are innovative
products such as Treasury Services' new NetConnect  Internet service that allows
customers to instantly  initiate  transactions.  All these  efforts  continue to
demonstrate our superior service to the middle market wherever we do business.

RIGHT STRATEGIES
INCREASE DIVERSE FEE REVENUE BASE

     For Senior Vice  President  Dave Sharpe and his staff at  TransFund,  rapid
growth  has  become  more the rule than the  exception.  TransFund  started as a
small,  proprietary  ATM  network  in  Tulsa in 1976,  but its  growth  has been
especially  vibrant since we embarked on a strategy six years ago to expand into
neighboring states.

     In 2002,  TransFund  emerged as the 12th largest  electronic funds transfer
(EFT)  network in the country  with  transaction  volumes in a  nine-state  area
surpassing  100  million  for the  first  time  and the  number  of  cardholders
exceeding  1.6  million.  Visa check card  transactions  rose 27 percent for the
year,  and  overall  transactions  were up 18 percent.  That capped  transaction
volume  growth of 146  percent  over five years with  merchant  card  processing
climbing 192 percent.

     TransFund is an important  part of BOK  Financial's  strategy of developing
fee-generating business lines that enable the company to expand earnings through
economic cycles. In 2002, revenue from fees and commissions grew 12 percent over
2001 and  accounted for 41 percent of revenue when  excluding  gains on sales of
securities and derivatives. That compares with a 30 percent average for banks in
our peer group.

     TransFund also  outperformed the industry,  according to Thomson's 2003 EFT
survey comparing March 2002 to March 2001. Our volumes were up 19 percent versus
an industry  average of 15 percent.  Sharpe and his staff  served 325  financial
institutions,  gaining  ground  in spite  of the  financial  industry's  ongoing
consolidation.

Pictures  of Dave Sharpe (SVP &  Mananger,  Transfund)  and JoAnn  Schaub (SVP &
Manager, Institutional and Employee Benefits) shown here.

See Transfund data in Appendix A.

See Employee Benefits data in Appendix A.

     Our Trust  Division  dates from the  founding in 1918 of  Oklahoma's  first
trust company and continues to pioneer revenue-generating  products. Senior Vice
President JoAnn Schaub,  manager of Institutional and Employee Benefits Trust in
Tulsa,  sees  first-hand the role that  innovative  products play in meeting our
customers'  needs.  I&EB  initiated  a  self-directed  401(k)  plan that  allows
participants to allocate their assets among mutual funds,  individual stocks and
bonds.  This  flexibility  has special appeal to law firms,  medical clinics and
other  professional  businesses  where a high  percentage  of  participants  are
motivated to manage their own  investments.  In 2002,  additional  self-directed
plans  contributed to an overall  increase in 401(k) plans of almost 10 percent.
New self-directed plans brought in $165 million in assets and more than $460,000
in additional revenue in 2002.

     Our diverse  non-interest  revenue base also includes fees and  commissions
from other trust services, deposit services, mortgage and international banking,
cash management,  and brokerage and trading. In fact, revenue grew 32 percent in
2002 from service charges and fees on deposit  accounts and increased 24 percent
at our BOSC, Inc. broker/dealer subsidiary.  International fee revenue was up 21
percent  with strong  growth along all product  lines and new business  from our
Exporters'  Plus  (SM)  document  preparation  service.  BOK  Financial  remains
committed to  introducing  innovative  products  and  services  that enhance and
diversify our revenue base and support our growth.

RIGHT RESULTS

See Loan graph data in Appendix A.

See Deposit graph data in Appendix A.

     Our values and  strategies  would be of little  consequence  if they didn't
produce right results for our stakeholders.  We again  demonstrated in 2002 that
right results emanate from consistently  applied strategies based on values that
promote  progress  and  growth on a solid  foundation  of  business  ethics  and
financial integrity.

     Net  income  of $150.4  million  for the year -  highest  in the  company's
history - resulted from  accomplishments by many individuals,  all working under
the umbrella of our corporate  goals.  Despite  margin  pressure and a generally
sluggish  environment during 2002, we achieved growth by most measures:  assets,
loans,  deposits,  net interest revenue, fees and commissions,  and earnings per
share.

     Our vision for 2003 looks  remarkably  similar to our past. In spite of the
challenges of an economic  slowdown and international  uncertainty,  we look for
new growth in 2003 and  beyond.  We will  continue  to follow  the four  primary
strategies outlined in this report, and we will pursue excellence in all that we
do. For our  shareholders,  customers and  employees,  the  combination of these
right strategies supported by right values will continue to produce results that
are right on the money.

MANAGEMENT'S ASSESSMENT OF OPERATIONS AND FINANCIAL CONDITION

     BOK Financial  Corporation ("BOK Financial") is a financial holding company
that offers full service  banking in Oklahoma,  Northwest  Arkansas,  Dallas and
Houston,  Texas metropolitan areas and Albuquerque,  New Mexico. BOK Financial's
principal subsidiaries are Bank of Oklahoma,  N.A. ("BOk"), Bank of Texas, N.A.,
Bank of Albuquerque, N.A., and Bank of Arkansas, N.A. Other subsidiaries include
BOSC, Inc., a broker/dealer that engages in retail and institutional  securities
sales and municipal underwriting.

CRITICAL ACCOUNTING POLICIES

APPLICATION OF CRITICAL ACCOUNTING POLICIES

     Preparation of BOK Financial's  consolidated  financial statements is based
on the selection of certain accounting  policies,  which requires  management to
make significant  assumptions and estimates.  The following discussion addresses
the more  critical  areas where these  assumptions  and  estimates  could affect
financial condition and results of operations.

     Application  of these critical  accounting  policies and estimates has been
discussed with the appropriate committees of the Board of Directors.

RESERVE FOR LOAN LOSSES

     The reserve for loan losses is assessed by management based upon an ongoing
evaluation of the probable estimated losses inherent in the portfolio, including
probable  losses on both  outstanding  loans and unused  commitments  to provide
financing.  A consistent,  well-documented  methodology  has been developed that
includes reserves assigned to specific loans, general reserves that are based on
a  statistical  migration  analysis and  nonspecific  reserves that are based on
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.  Specific reserves
for impairment are determined  through evaluation of estimated future cash flows
and  collateral  values in  accordance  with  Statement of Financial  Accounting
Standards No. 114,  "Accounting  by Creditors for the  Impairment of a Loan" and
regulatory accounting standards.

     The general  reserve for commercial and commercial  real estate loan losses
is determined  primarily  through an  internally  developed  migration  analysis
model.  The purpose of this model is to determine the probability that each loan
in the portfolio has an inherent loss based on historic trends.  Management uses
an eight-quarter aggregate accumulation of net losses as a basis for this model.
Greater  emphasis is placed on loan losses in more  recent  periods.  This model
assigns a general  reserve for loan losses to all  commercial  loans and leases,
excluding loans that have a specific  impairment reserve,  residential  mortgage
loans, excluding loans held for sale, and consumer loans.

     Separate  models are used to determine  general  reserves  for  residential
mortgage loans,  excluding loans held for sale, and consumer loans.  The general
reserve for  residential  mortgage  loans is based on an  eight-quarter  average
percent of loss. General reserves for consumer loans are based on a migration of
loans from current status to loss.  Separate migration factors are determined by
major loan  products,  such as  indirect  automobile  loans and direct  consumer
loans.

     A nonspecific  reserve for loan losses is maintained for risks beyond those
factors  specific to a  particular  loan or those  identified  by the  migration
models.  These factors include trends in the 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 and
overall growth in the loan  portfolio.  Additional  factors  considered are bank
regulatory examination results, error potential in the migration analysis models
or the underlying data and other relevant  factors.  A range of potential losses
is determined for each factor identified.

VALUATION AND AMORTIZATION OF MORTGAGE SERVICING RIGHTS

     BOK Financial has a significant  investment in mortgage  servicing  rights.
These rights are either  purchased  from other lenders or retained from sales of
loans originated by BOK Financial in the secondary  market.  Mortgage  servicing
rights are carried at the lower of amortized  cost,  adjusted for the effects of
past  hedging  activities,  or fair  value.  Amortized  cost and fair  value are
stratified  by interest  rate and loan type.  A valuation  allowance is provided
when the net amortized cost of any strata exceeds the calculated fair values.

     There is no active  market for trading in mortgage  servicing  rights.  BOK
Financial uses a cash flow model to determine fair value.  Key  assumptions  and
estimates,  including  projected  prepayment speeds and assumed servicing costs,
earnings on escrow deposits,  ancillary income and discount rates,  used in this
model are provided by independent  sources.  During 2002, BOK Financial  changed
the  source  of  prepayment  assumptions  used to value its  mortgage  servicing
rights.  Previously,  industry consensus  prepayment speeds were used to project
future cash flows. This information was not updated frequently enough to reflect
current  market  conditions.  A separate  third-party  model  that is  generally
accepted  by the  financial  markets is now used to estimate  prepayment  speeds
based upon interest rates,  housing turnover rates,  estimated loan curtailment,
anticipated defaults and other relevant factors. The prepayment model is updated
daily for changes in market conditions. Published sources are generally used for
other key assumptions and estimates.  Management periodically requests estimates
of fair value from outside  sources to corroborate  the results of the valuation
model.

11

     Prepayment  assumptions also affect the amortization of mortgage  servicing
rights.  Amortization  is determined in proportion to projected  cash flows over
the  estimated  life of each loan  serviced.  The same  third  party  model that
estimates prepayment speeds for determining the fair value of mortgage servicing
rights determines the estimated life of each loan serviced.

INTANGIBLE ASSETS

     During  2002,   Statements  of  Financial  Accounting  Standards  No.  142,
"Goodwill and Other Intangible Assets" ("FAS 142") and No. 147, "Acquisitions of
Certain  Financial  Institutions"  ("FAS  147") were  adopted.  These  standards
eliminated  amortization  of intangible  assets with indefinite  lives,  such as
goodwill.  Instead,  goodwill for each of BOK Financial's business units must be
evaluated for  impairment  annually or more  frequently  if conditions  indicate
impairment  may  have  occurred.   The  evaluation  of  possible  impairment  of
intangible  assets  involves  significant  judgment  based upon  short-term  and
long-term projections of future performance.

     The fair  value of BOK  Financial's  business  units  is  estimated  by the
discounted  future earnings method.  Income growth is projected over a five-year
period for each unit and a terminal  value is computed.  This  projected  income
stream is converted to current fair value by using a discount rate that reflects
a rate of return required by a willing buyer.

     At December  31,  2002,  Bank of Texas had $155 million or 87% of goodwill.
Because of the large  concentration  of goodwill in this business unit, the fair
value determined by the discounted  future earnings method for Bank of Texas was
corroborated by comparison to the fair value of publicly traded banks of similar
size and  characteristics.  No  goodwill  impairment  was  indicated  by  either
valuation method.

SUMMARY OF PERFORMANCE

     BOK  Financial  recorded net income of $150.4  million or $2.48 per diluted
share for 2002  compared to $116.3  million or $1.95 per diluted share for 2001.
Prior  years'  earnings  per share  have  been  restated  to  reflect a 3% stock
dividend in 2002.  Returns on average  assets and average  equity were 1.33% and
16.07%, respectively,  for 2002 compared to 1.14% and 14.93%, respectively,  for
2001.

     If FAS 142 and FAS 147 had been  applied  retroactively  to  2001,  the pro
forma net income and earnings per diluted  share would have been $125.5  million
and $2.10,  respectively.  Return on average  assets and average equity for 2001
would have been 1.23% and 16.11%.

     Net income for 2000 was $100.1 million or $1.69 per diluted share.  Returns
on average assets and equity were $1.15% and 16.46%. Net income in 2000 included
a $3.0 million reduction in income tax expense due to favorable resolution of an
Internal  Revenue Service  examination.  If FAS 142 and FAS 147 had been applied
retroactively to 2000, net income and diluted earnings per share would have been
$105.3  million or $1.78,  respectively.  Return on average  assets and  average
equity for 2000 would have been 1.21% and 17.31%.

     Return on average equity is impacted by the change in unrealized  gains and
losses of securities due to the changes in the market valuation of available for
sale  securities.  Excluding these  unrealized gains and losses on securities in
addition to the effects of FAS 142 and FAS 147,  return on average  equity would
have been 16.57%, 16.51% and 16.23% in 2002, 2001 and 2000, respectively.

     Net interest revenue grew $39.2 million or 12% during 2002 due to increases
in average  earning  assets,  partially  offset by the net  effect of  declining
interest rates. Fees and commissions grew $28.3 million or 12% with increases in
service  charges and fees on deposit  accounts,  transaction  card revenue,  and
brokerage and trading  revenues and decreases in trust fees and  commissions and
mortgage  banking  revenues.  Gains on sales of securities,  including  gains on
sales  of  securities  used  as an  economic  hedge  of  the  mortgage-servicing
portfolio,  increased $28.1 million. Operating expenses for 2002 increased $56.9
million or 15% over 2001 due to a $42.4 million  increase in expenses related to
mortgage banking  activities and a $19.5 million increase in personnel  expense,
partially  offset by a $12.5  million  decrease in  amortization  of  intangible
assets.

     Net income for the fourth  quarter 2002  increased  29% to $38.8 million or
$0.63 per  diluted  common  share.  This  increase  included an increase of $6.6
million or 7% in net  interest  revenue,  an $8.1 million or 13% increase in fee
and  commission  revenue  and an  $18.1  million  increase  in gains on sales of
securities  and gains on derivative  contracts.  These  increases were offset by
increases in operating expense of $20.2 million or 24%.

ASSESSMENT OF OPERATIONS

NET INTEREST REVENUE

     Tax-equivalent  net  interest  revenue  totaled  $374.3  million  for  2002
compared to $337.0  million for 2001.  The increase in net interest  revenue was
due primarily to a $1.1 billion  increase in average  earning assets offset by a
$622 million  increase in  interest-bearing  liabilities.  The growth in average
earning assets included a $698 million increase in securities and a $395 million
increase in net loans. The increase in average interest-bearing  liabilities was
due to growth in  average  interest-bearing  deposits  of $640  million,  offset
slightly by a net decrease in other  borrowings.  Table 2 reflects the effect on
net interest  revenue of changes in average  balances and interest rates for the
various types of earning assets and interest-bearing liabilities.

     Yields on average earning assets and rates paid on average interest-bearing
liabilities both continued to decline  throughout 2002. The net interest margin,
the ratio of  tax-equivalent  net interest  revenue to average  earning  assets,
increased to 3.70% for 2002 compared to 3.66% for 2001. This increase  reflected
the effects of changes in interest rates on BOK  Financial's  earning assets and
interest-bearing  liabilities.  During the first quarter of 2002 BOK Financial's
interest-bearing  liabilities  reacted more quickly to changes in interest rates
than its earning  assets,  causing the net interest  margin to increase during a
period of declining  interest rates.  This favorable  effect of falling interest
rates began to decline  after the first quarter of 2002 as the yields on earning
assets  continued to decrease and the  over-all  rates paid on  interest-bearing
liabilities  became more stable.  The effects of the declining interest rates on
yields and rates paid  during  2002 are  reflected  in the Annual and  Quarterly
Financial Summaries.

     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.  This
strategy  also reduces  total  interest  rate risk.  The interest  rate on these
borrowed  funds,  which  generally  reacts quickly to changes in market interest
rates,  tends to match  the  effect of  changes  in  interest  rates on the loan
portfolio.  Interest rates earned on the securities  purchased with the proceeds
of these borrowed funds are affected less quickly by changes in market  interest
rates. The timing of changes in interest rates earned on securities more closely
matches  the  timing of  changes in  interest  rates  paid on deposit  accounts.
Although  this  strategy  may result 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 this strategy enhanced net interest
revenue $67 million during 2002, compared to $39 million in 2001. Excluding this
strategy, net interest margin for 2002 and 2001 would have been 3.76% and 3.95%,
respectively.  Average  securities  purchased  and  funds  borrowed  under  this
strategy  were $1.9  billion  in 2002 and $1.7  billion  in 2001.  As more fully
discussed in the  subsequent  Market Risk Section,  management  employs  various
techniques  to manage,  within  established  parameters,  the interest  rate and
liquidity risk inherent in this strategy.  The effectiveness of these strategies
is  reflected in the overall  changes in net interest  revenue due to changes in
interest rates as shown in Table 2.

     Tax-equivalent  net  interest  revenue  for the fourth  quarter of 2002 was
$95.7  million  compared to $89.5  million  for the fourth  quarter  2001.  This
increase was due to the growth in average earning  assets,  which increased $1.3
billion or 14%. Net interest  margin declined 17 basis points to 3.55% as yields
in earning  assets  decreased  more  rapidly  than the cost of interest  bearing
liabilities due to the effect of declining rates over the past year as discussed
above.

     Tax-equivalent  net  interest  revenue  totaled  $337.0  million  for  2001
compared to $277.7  million for 2000.  The increase in net interest  revenue was
primarily due to an increase in average earning  assets.  Average earning assets
increased  by $1.4  billion  during  2001 due most  notably to average  net loan
growth of $1.0 billion.  This growth in loans improved the mix of earning assets
since loans generally have higher yields than other types of earning assets. The
growth in  average  earning  assets  was funded by a $1.2  billion  increase  in
interest-bearing   liabilities,   including   an  $845   million   increase   in
interest-bearing deposits.

     The financial  services  environment in BOK Financial's  primary markets is
highly  competitive due to a large number of commercial banks,  thrifts,  credit
unions and brokerage firms. Additionally, many customers have access to national
and regional financial  institutions for many products and services.  Management
expects that BOK Financial will continue to be able to successfully compete with
these  financial  institutions  by delivering the loan and deposit  products and
other  financial  services  traditionally  associated with a large bank with the
responsiveness of a smaller, community bank.

OTHER OPERATING REVENUE

     Other  operating  revenue  increased $66.9 million or 26% compared to 2001.
Fees and  commissions  increased $28.3 million or 12% compared to 2001. Fees and
commissions continue to represent a significant portion of BOK Financial's total
revenue at 41%,  excluding gains on securities and  derivatives,  during 2002. A
significant  portion  of the  increase  in fees  and  commissions  is due to the
increase in service charges and fees on deposit accounts of $16.3 million or 32%
primarily from an overdraft  privilege  product  initiated in 2002.  Transaction
card  revenues  have  increased  $9.1  million or 20% over 2001 due to growth in
merchant fees, ATM network fees  (TransFund) and check card fees.  Brokerage and
trading  fees have  increased  $4.8  million or 24% during 2002 due to increased
institutional  sales.  Trust fees  declined  $475  thousand  during  2002 due to
declines  in the asset  values on which  many fees are based.  Mortgage  banking
revenue decreased $1.2 million,  see discussion of mortgage banking in the lines
of business section of this report.

     BOK Financial realized net gains on sales of securities of $58.7 million in
2002 and $30.6 million in 2001. These amounts included net gains from securities
designated  as  economic  hedges of the  mortgage-servicing  portfolio  of $26.3
million in 2002 and $12.8  million in 2001.  The increase in net realized  gains
reflected the active  management of the  securities  portfolio as interest rates
declined during 2002.  Management's  strategy during 2002 was to sell securities
that had limited  potential  for further  appreciation  and to replace them with
securities  with  less  prepayment  risk.  Net  gain  on  derivatives  primarily
represented  the mark to market of the  derivative  portfolio  used for interest
rate risk management.  Additional  discussion  regarding the mortgage  servicing
rights  and  related  hedge  portfolio  and BOK  Financial's  use of  derivative
instruments is located in the Market Risk section of this report.

     Other operating revenue for the fourth quarter of 2002, excluding net gains
on sales of securities and gains on derivatives,  totaled $69.7 million compared
to $61.6 million for the fourth quarter 2001.  Service charges during the fourth
quarter 2002 increased $5.3 million or 38% over same period of 2001. Transaction
card revenue  increased $2.5 million or 22% for the fourth quarter 2002 over the
previous period. Brokerage and trading revenue increased $1.5 million or 29% for
the fourth quarter 2002 as compared to 2001.

     The  fourth  quarter of 2002  included  securities  gains of $10.3  million
compared to securities  losses of $3.8 million during the fourth quarter of 2001
and gains on derivatives of $665 thousand in 2002 compared to derivatives losses
of $3.3 million in 2001. Net securities  gains from the portion of the available
for sale  portfolio,  which  serves as an economic  hedge of mortgage  servicing
rights, totaled $6.8 million for the fourth quarter of 2002 compared to an $11.1
million loss in the same period of 2001.

     Other  operating  revenue in 2001 increased $34.6 million or 18% from 2000,
excluding a $24.5  million  increase  from gains on financial  instruments.  All
major categories of fees and commissions increased over the same period in 2000.
Most notably,  mortgage-banking revenue increased $13.0 million or 35% from 2000
due to improved conditions for sales of loans into the secondary market. Service
charges and fees on deposit  accounts  grew $8.4 million or 19% over 2000 due to
growth in nonsufficient  fund charges and growth of treasury  services  revenue.
Brokerage  and  trading  revenue  grew 30% to $19.6  million  during 2001 due to
diversification into corporate bonds,  favorable reception to the product mix in
our newer markets and continued expansion in revenue from traditional  brokerage
products.  Growth in transaction  card revenue of $5.7 million or 15% was due to
growth in merchant fees.

     Management  expects continued growth in other operating  revenue.  However,
increased  competition,  market  saturation  and the level of economic  activity
could affect the future rate of increase.  Additionally, BOK Financial's ability
to generate  fee revenue is  affected  by interest  rates,  values in the equity
market and consumer spending, all of which can be volatile.

LINES OF BUSINESS

     BOK Financial  operates four principal  lines of business under its Bank of
Oklahoma  ("BOk")  franchise:  corporate  banking,  consumer  banking,  mortgage
banking and trust services. It also operates a fifth line of business,  regional
banks, which includes all banking functions for Bank of Albuquerque,  N.A., Bank
of Arkansas,  N.A., and Bank of Texas,  N.A. Other lines of business include the
TransFund ATM network and BOSC, Inc., a securities broker/dealer. In addition to
its lines of business,  BOK Financial has a funds  management  unit. The primary
purpose of this unit is to manage the overall  liquidity needs and interest rate
risk of the company. Each line of business borrows funds from and provides funds
to the funds management unit as needed to support their operations.

     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 the expected  duration of the accounts.  The expected  duration
ranges from 90 days for certain  rate-sensitive  deposits to five years.  During
2002, the average  transfer-pricing rate for these deposit accounts decreased by
approximately 200 basis points.  Since many of these deposit accounts are either
noninterest bearing accounts or interest-bearing  accounts whose rates cannot be
readily   reset   lower  due  to  market   constraints,   the   decline  in  the
transfer-pricing  rates shifted net interest  revenue from providers of funds to
the funds  management  unit.  This is reflected  in net interest  revenue of the
funds management unit, which increased by $58 million to $73 million in 2002.

     The following  table  summarizes  the effects that the transfer  pricing of
deposits with indeterminate maturities had on the lines of business as an aid to
analyzing performance in 2002.

     Economic  capital is  assigned to the  business  units based on an internal
allocation method that reflects management's  assessment of risk as if they were
stand-alone entities.  Additional capital is assigned to the regional banks line
of business based on BOK Financial's investment in those entities. The aggregate
economic   capital   assigned  to  the  lines  of  business   does  not  reflect
interdependencies  among the lines of business and exceeds the capital  required
by BOK  Financial in total.  Total capital  required by BOK  Financial  reflects
management's estimate of capital required by the Company as a whole.

     The  provision for loan losses  assigned to each line of business  reflects
actual charge-offs,  net of recoveries.  The aggregate provision for loan losses
charged to the lines of business will differ from the consolidated provision for
loan losses based on the timing of net charge-offs.

CORPORATE BANKING

     The  Corporate  Banking  Division  provides  loan and lease  financing  and
treasury and cash  management  services to  businesses  throughout  Oklahoma and
seven surrounding  states.  BOk's Corporate Banking Division includes the Denver
loan  production  office.  In addition  to serving  the  banking  needs of small
businesses,  middle market and larger customers,  the Corporate Banking Division
has  specialized  groups  that  serve  customers  in  the  energy,  agriculture,
healthcare  and  banking/finance  industries.  The  Corporate  Banking  Division
contributed $48.2 million or 32% to consolidated net income for 2002 compared to
$45.6 million or 39% for 2001. The decline in net interest revenue from external
sources is due to the  decline in market  rates on loans  which is offset by the
decline  in  net  interest  expense  from  internal  sources  due  to  declining
transfer-pricing  rates, as discussed above.  Other operating  revenue increased
$3.2  million  or 11% over 2001 due  mostly to  increases  in  activity  fees on
treasury  service  products.  Operating  expenses  increased  slightly  to $58.3
million in 2002 compared to $57.3  million in 2001.  The provision for loan loss
represents  net  loans  charged  off or  recovered  for  the  Corporate  Banking
Division.

CONSUMER BANKING

     The Consumer  Banking  Division  provides a full line of deposit,  loan and
fee-based  services  to  customers   throughout   Oklahoma  through  four  major
distribution channels:  traditional branches,  supermarket branches, the 24-hour
ExpressBank  call  center and the  Internet.  Additionally,  the  division  is a
significant  referral  source for the Bank of Oklahoma  Mortgage  Division ("BOk
Mortgage") and BOSC's retail brokerage  division.  The Consumer Banking Division
contributed  $6.8  million or 4% to  consolidated  net income for 2002 and $16.5
million or 14% for 2001. Revenue from internal sources, primarily funds provided
to other business lines,  decreased $33.1 million due to lower  transfer-pricing
rates. At the same time,  interest expense from external sources decreased $16.2
million due to lower interest paid on deposit accounts.  Other operating revenue
increased  $8.9  million or 30% over 2001 due  primarily to increases in service
charges from an overdraft  privilege product initiated during the second quarter
of 2002.  The increase in provision  for loan loss during 2002 of $3.6  million,
which represents  actual net charge-offs,  included $766 thousand of charge-offs
from the  overdraft  privilege  product and $1.7 million to indirect auto loans.
Operating  expenses  increased  $4.3 million or 7% to $63.4  million for 2002 as
compared to 2001,  which included a $2.4 million increase in personnel costs due
mostly to incentive compensation.

MORTGAGE BANKING

     BOK  Financial  engages in  mortgage  banking  activities  through  the BOk
Mortgage Division of Bank of Oklahoma. These activities include the origination,
marketing and servicing of conventional and government-sponsored mortgage loans.
BOk Mortgage  contributed $1.6 million or 1% to consolidated net income for 2002
compared to $8.5 million or 7% for 2001.

     BOk  Mortgage  is  comprised  of two  sectors,  loan  production  and  loan
servicing.  The loan  production  sector  generally  performs best when mortgage
interest rates are low and loan origination  volumes are high.  Conversely,  the
loan servicing sector generally  performs best when mortgage  interest rates are
relatively  high and  prepayments  are low. The  historically  low mortgage loan
interest  rate  environment  during  2002  produced  net  profits  for the  loan
production sector and net losses for the loan servicing sector.

LOAN PRODUCTION SECTOR

     Revenue from loan production was $27.4 million,  including $20.8 million of
capitalized servicing rights, for 2002, compared to revenue from loan production
of $17.8 million,  including $22.7 million of capitalized  servicing rights, for
2001.  The  increase  in net loan  production  revenue,  excluding  the value of
capitalized  servicing  rights,  was due to an improved market for loan sales in
2002. The value of mortgage loans sold increased over the year as interest rates
declined.  Mortgage loans funded  totaled $1.3 billion for 2002,  including $557
million for home purchases and $696 million of loan  refinanced.  Mortgage loans
funded in 2001 totaled $1.1 billion,  including  $562 million for home purchases
and $566  million  of loan  refinanced.  Approximately  77% of the loans  funded
during 2002 were in Oklahoma. The largest growth in loans funded occurred in the
Dallas  market with an increase of $45 million to $103  million of loans  funded
for the year. The combination of increased loan  production  volume and value of
loans sold increased  pre-tax  income from  production to $23.7 million for 2002
compared to $12.1 million for 2001.

LOAN SERVICING SECTOR

     The loan-servicing  sector incurred a pre-tax loss of $22.5 million in 2002
compared to pre-tax income of $378 thousand in 2001. This was due to the effects
of falling  interest  rates on both  actual and  anticipated  loan  prepayments.
Actual  mortgage  loan  prepayments  reduce  the  outstanding  balance  of loans
serviced,  which is the primary factor for determining servicing revenue. Actual
and   anticipated   loan   prepayments  are  also  key  factors  in  determining
amortization  expense  and the fair  value  of  servicing  rights.  Amortization
expense  increases  and the fair value of  servicing  rights  decrease  whenever
prepayment speeds are high.  Conversely,  amortization expense decreases and the
fair value of servicing rights increase whenever prepayment speeds are low. Both
actual and  anticipated  prepayment  speeds were high during 2002 as a result of
the historically low mortgage interest rates.

     Mortgage servicing revenue totaled $28.2 million for 2002 compared to $32.3
million for 2001. The decrease in mortgage  servicing  revenue was due primarily
to a  lower  outstanding  principal  balance  of  loans  serviced.  The  average
outstanding  principal balance of loans serviced decreased by 8% to $6.2 billion
during 2002. The  outstanding  principal  balance of mortgage loans serviced was
$5.8 billion at December 31, 2002.  This  decrease in loans  serviced  reflected
both the rapid  refinancing of mortgages and BOk Mortgage's  decision to curtail
purchases of mortgage  servicing.  This decision  also  affected the  geographic
distribution of BOk Mortgage's  servicing  portfolio.  Approximately  69% of the
loans serviced were in BOK Financial's  primary market area at December 31, 2002
compared to 60% at December 31, 2001.

     Amortization of mortgage  servicing rights,  which is included in operating
expense,  increased  by $12.5  million to $36.0  million for 2002.  Amortization
expense is determined  in  proportion  to the  estimated  cash flow that will be
generated by the mortgage servicing rights.

     The valuation allowance for impairment of mortgage servicing rights totaled
$55 million at December  31, 2002  compared to $18 million at December 31, 2001.
An impairment  provision of $45.9 million was recognized during 2002 compared to
an  impairment  provision of $15.6 million in 2001. As discussed in the Critical
Accounting  Policies section of this report,  BOK Financial provides a valuation
allowance to reduce the carrying value of its mortgage  servicing  rights to the
lower  of  fair  value  or  amortized  cost  segregated  by  impairment  strata.
Impairment  strata are  determined  by  interest  rate bands and by loan  types,
either conventional or government-backed.  The fair value of servicing rights is
based on estimated  revenues that will be generated  over the servicing  period,
less  estimated  costs to service  the loans.  The  valuation  allowance  may be
reversed  in part or in  whole,  if the fair  value  of  servicing  rights  in a
particular  impairment  strata  increase.  This may  occur if  anticipated  loan
prepayment  speeds  decrease.  Note 8 to the Consolidated  Financial  Statements
presents additional information about fair value and amortized cost of servicing
rights and valuation allowance.

17

     BOK  Financial  designates  a portion  of its  securities  portfolio  as an
economic  hedge  against  the  risk of loss on its  mortgage  servicing  rights.
Mortgage-backed  securities and U.S.  government  agency debentures are acquired
and held as available for sale when prepayment risks exceed certain levels.  The
fair value of these  securities is expected to vary  inversely to the fair value
of the servicing rights.

     Management  may sell these  securities  and  realize  gains or losses  when
necessary to offset the impairment  provision of the mortgage  servicing rights.
During  2002,  BOK  Financial  realized  gains of  $26.3  million  from  hedging
activities  compared  to gains of $12.8  million in 2001.  See the  Market  Risk
section of this report for additional  discussion of the prepayment  risk of the
mortgage servicing portfolio and related hedging strategies.

TRUST SERVICES

     BOK  Financial   provides  a  wide  range  of  trust  services,   including
institutional,  investment  and  retirement  products  and  services to affluent
individuals,   businesses,   not-for-profit   organizations,   and  governmental
agencies.  Trust services are primarily provided to clients in Oklahoma,  Texas,
Arkansas  and New Mexico.  Additionally,  Trust  Services  include a  nationally
competitive,  self-directed 401-(k) program with clients in Dallas, Chicago, New
York and Los  Angeles.  At  December  31,  2002 and 2001,  trust  assets with an
aggregate  market  value of $17  billion  and $18  billion,  respectively,  were
subject to  various  fiduciary  arrangements.  BOK  Financial  has sole or joint
discretionary  authority  over $8 billion of trust  assets at December  31, 2002
compared to $10 billion of trust  assets at December 31,  2001.  Trust  Services
contributed  $6.2  million  or 4% of  consolidated  net income for 2002 and $9.7
million or 8% for 2001.  Net interest  revenue from internal  services  declined
$5.2 million or 38% due to lower transfer pricing rates. Other operating revenue
declined  $1.0  million  compared to 2001 due to declines in the asset values on
which many fees are based.

REGIONAL BANKS

     Regional  banks  include Bank of Texas,  Bank of  Albuquerque,  and Bank of
Arkansas.  Each of these banks  provides a full range of corporate  and consumer
banking services in their respective markets. Small businesses and middle-market
corporations are the regional banks' primary customer focus.

     Regional banks  contributed $35.6 million or 24% to consolidated net income
for 2002 and $31.8 million or 27% for 2001.  Net interest  revenue from external
customers  declined $1.7  million.  A $523 million  increase in average  earning
assets  contributed $32.5 million to net interest revenue from external sources,
offset by a $10 million  increase in the cost of  interest-bearing  liabilities.
The  increase  in net  interest  revenue  from  external  sources  was offset by
declining  interest rates. Other operating revenue increased $7.2 million or 37%
due to increases  merchant fees,  mostly from new business in Texas, and service
charges on deposit accounts,  due to an overdraft privilege product initiated in
2002.  Operating  expenses increased $2.3 million or 3% including a reduction of
goodwill amortization of $7.6 million from the implementation of FAS 142 and FAS
147.  Excluding the effect of FAS 142 and FAS 147,  operating expenses increased
$9.9 million or 12% due largely to an increase in personnel cost.

     BOK Financial's  operations in Texas,  New Mexico and Arkansas  contributed
$23.9 million, $10.4 million and $1.3 million, respectively, to consolidated net
income for 2002 compared to net income of $21.1 million,  $8.2 million, and $2.5
million, respectively, for 2001.

regional  banks  based on tangible  net  income,  return on assets and return on
equity.  Tangible net income is defined as net income  excluding  the  after-tax
effect of goodwill and core deposit intangible asset amortization.

OTHER OPERATING EXPENSE

     Other operating  expense for 2002 increased $56.9 million or 15% over 2001.
Mortgage  banking  costs  increased  $12.0  million or 40% due to an increase in
amortization of capitalized mortgage servicing rights. An impairment of mortgage
servicing  rights of $45.9 million was also recognized due to market  conditions
existing  during this time.  These market  conditions and impact on the mortgage
banking  business  are more  thoroughly  discussed  in the Lines of  Business  -
Mortgage  Banking  section of this report.  Excluding the increases in provision
for  impairment  of  mortgage  servicing  rights and  amortization  of  mortgage
servicing rights, other operating expense increased $14.0 million or 4%.

     Personnel  costs increased $19.5 million or 12%, of which $11.6 million was
salaries  and benefits  attributable  to a 10% increase in salaries and benefits
per FTE,  plus a $4.7  million  increase in incentive  bonuses tied  directly to
production.  Data  processing and  communications  increased  during 2002,  $7.2
million or 18% as compared to 2001.  Included in the increase in data processing
were increases in transaction  card processing  fees of $4.2 million,  which are
directly  related to the increase in  transaction  card revenue of $9.1 million.
Also  included in the  increase  in data  processing  was a $2.0  million or 14%
increase in external data processing due to increased transaction volumes.

     Amortization  of intangible  assets  decreased $12.5 million during 2002 as
compared to 2001. The  implementation of FAS 142 and FAS 147 accounted for $10.2
million of the change during 2002, as previously  discussed.  If these rules had
been  applied  retroactively  to the prior year,  operating  expense  would have
decreased  $10.2  million for 2001 and $2.6  million  for the fourth  quarter of
2001.

     During the third quarter of 2002, BOK Financial  entered into a contract to
change its primary data processing  servicer.  Expenses incurred to date on this
project totaled $987 thousand and quarterly  operating  expenses are expected to
increase by amounts  ranging  from $950  thousand to $1.6  million over the next
year.  Management  anticipates  this  change to occur  during the second half of
2003.

     Operating  expenses for the fourth  quarter of 2002 totaled  $105.0 million
compared to $84.8 million for the fourth  quarter of 2001. The fourth quarter of
2002 included a $1.6 million  reversal of previous  provisions for impairment of
mortgage  servicing  rights  compared  to an  $8.9  million  reversal  in  2001.
Amortization of mortgage  servicing rights during the fourth quarter of 2002 was
$12.9  million  compared  to $7.9  million  during  the  same  quarter  of 2001.
Excluding the effects of this impairment  reversal and  amortization on mortgage
servicing rights, operating expenses for the fourth quarter of 2002 increased by
9% from 2001 due to reasons consistent with those discussed above.

     Other operating  expense totaled $368.8 million for 2001 compared to $302.8
million for 2000. Excluding a $15.6 million provision for impairment of mortgage
servicing  rights in 2001  compared to $2.9 million in 2000 and $20.7 million of
operating  expenses from the CNBT acquisition in 2001,  other operating  expense
increased $32.5 million or 11% from 2000. The following discussion excludes CNBT
operating  expenses  (personnel of $6.3 million,  net occupancy and equipment of
$1.7 million and  amortization of intangible  assets of $7.4 million) to improve
comparability.

     Personnel  costs  increased  $11.4  million  or  8%.  Regular  compensation
(including   overtime  and   temporary   assistance)   and  benefits   increased
$9.3 million  or 7%. Average  staffing on a full time  equivalent  ("FTE") basis
increased by 141  employees or 5%, while  average  compensation  expense per FTE
increased  by 3%.  Incentive  compensation  increased  by  $2.0  million  or 10%
compared  to  2000  due  to  growth  in  revenue  over  pre-determined  targets.
Professional  fees for 2001  increased  $3.4 million or 36%, which included $1.5
million in consulting  fees for public finance  business at BOSC,  Inc. and $320
thousand for the Perfect  Banking sales and service  program.  Net occupancy and
equipment expense for 2001 increased $5.6 million or 16% due primarily to a $3.2
million  increase in depreciation  expense.  This increase  reflects  additional
investments in facilities and technology  improvements  over the past two years.
Data  processing and  communications  increased $4.4 million or 13% primarily in
transaction  card servicing and external  processing  due to increased  volumes.
Mortgage   banking  costs  increased  $8.0  million  or  36%  due  primarily  to
amortization  of mortgage  servicing  rights,  which is caused by an increase in
loan  prepayments.  A provision for impairment of mortgage  servicing  rights of
$15.6  million was taken  during 2001 due  primarily  to the  interest  rate and
prepayment environment.

INCOME TAXES

     Income tax expense was $82.4  million,  $63.6 million and $47.6 million for
2002, 2001 and 2000, respectively,  representing 35%, 35% and 32%, respectively,
of book taxable income.  Tax expense currently payable totaled  $95.9 million in
2002 compared to $74.2 million in 2001 and $38.4 million in 2000.

     The Internal Revenue Service is currently  examining the carryback of $30.8
million of capital loss generated in 1999. Such loss was applied against capital
gains generated in 1997 and 1998 resulting in a $9.8 million refund.  Management
expects no material  adverse  impact on the financial  statements as a result of
this examination.

     The Internal Revenue Service closed its examination of 1996 during 2000. As
a result of the  outcome of this  examination,  BOK  Financial  reduced  its tax
accrual by $3.0  million.  Income tax expense  for 2000 was 34% of pre-tax  book
income, excluding the reversal of this accrual.

ASSESSMENT OF FINANCIAL CONDITION

SECURITIES PORTFOLIO

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

     During 2002, the amortized cost of available for sale securities  increased
by $423 million.  Mortgage-backed  securities  increased by $426 million and now
represent  97% of total  available  for  sale  securities.  Approximately,  $210
million of the increase in mortgage-backed  securities  reflects BOK Financial's
strategy of fully utilizing  available  capital  resources by borrowing funds in
the capital markets, as previously discussed in the Net Interest Revenue section
of this report.  Mortgage-backed  securities  designated as an economic hedge of
the mortgage  servicing  portfolio  decreased  $235 million to $127 million.  At
December 31, 2002,  available for sale securities with an amortized cost of $2.0
billion were pledged as collateral for repurchase agreement borrowings, deposits
of public funds and other purposes.

     Net  unrealized  gains  in the  available  for  sale  securities  portfolio
increased  from $10 million at December  31, 2001 to $71 million at December 31,
2002,  due  primarily to lower  interest  rates.  The  expected  duration of the
mortgage-backed  securities portfolio is 2.0 years. Additional information about
the securities  portfolio is presented in Note 3 to the  Consolidated  Financial
Statements.

loans at December 31, 2002. This  represented an increase of 15% over last year.

million  of  home  equity  loans,  $249  million  of  loans  held  for  business
relationship  purposes,  $233 million of adjustable rate mortgage loans and $112
million of loans held for community development.  Adjustable rate mortgage loans

ENERGY DERIVATIVES WITH CREDIT RISK

     BOK Financial offers a program that permits its energy-producing  customers
to hedge against price fluctuations and take positions through energy option and
swap  contracts.  These  contracts are executed  between BOk and its  customers.
Offsetting  contracts are executed  between BOk and selected  energy  dealers to
minimize  the risk of  changes  in  energy  prices.  The  dealer  contracts  are
identical to the customer  contracts,  except for a fixed pricing spread paid to
BOk as compensation for administrative costs, credit risk and profit.

     This program creates credit risk for potential  amounts due to BOk from its
customers and energy dealers. Customer credit risk is monitored through existing
lending policies and procedures.  The value of energy production,  which secures
customer contracts, is evaluated across a range of prices to determine a maximum
exposure BOk is willing to have individually to any customer. Customers may also
be required to provide  collateral in addition to the value of energy production
to further limit credit risk.

     Dealer credit risk is monitored  through  existing  policies and procedures
used to evaluate  counterparty risk. This evaluation considers all relationships
among BOK Financial and each counterparty.  Individual limits are established by
management and approved by the Risk  Oversight and Audit  Committee of the Board
of Directors.  Margin collateral is required if the exposure between BOk and any
counterparty exceeds established limits. These limits are reduced and additional
margin collateral is required if a dealer's credit rating is downgraded.

     BOK  Financial  carries the energy  contracts at fair value in other assets
and  liabilities.  At December 31, 2002,  other assets  included $71 million and
other liabilities included $71 million of energy contracts. Approximately 73% of
the fair value of asset  contracts  are with  customers  of BOK  Financial.  The
remaining 27% are with energy dealers,  primarily J. P. Morgan-Chase and Bank of
Montreal. Conversely, approximately 73% of the fair value of liability contracts
are with  energy  dealers,  primarily  Morgan  Stanley,  Coral  Energy and J. P.
Morgan-Chase.  The remaining 27% are with various customers.  A deterioration in
the credit  standing of one or more  counterparties  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 a counterparty  deteriorated  such that either the fair value of the
energy production no longer supported the contract or the counterparty's ability
to provide margin collateral was impaired.

     The growth in the fair value of energy contracts during 2002 reflected both
new business  added during the year and increased  energy  prices.  New business
grew by approximately $2.6 million based on anticipated revenue to be recognized
over the life of the contracts.

SUMMARY OF LOAN LOSS EXPERIENCE

     The reserve for loan losses,  which is available to absorb losses  inherent
in the loan  portfolio,  totaled $116  million at December 31, 2002  compared to
$102 million at December 31, 2001. These amounts  represented 1.72% and 1.66% of
total  loans,  excluding  loans held for sale,  at  December  31, 2002 and 2001,
respectively.  Losses  on  loans  held  for  sale,  principally  mortgage  loans
accumulated  for placement in security  pools,  are charged to earnings  through
adjustments in the carrying value.  The reserve for loan losses also represented
233% of  nonperforming  loans at December 31, 2002  compared to 234% at December
31, 2001. Net loans charged off during 2002 remained  constant from the previous
year at $21 million.  Improved  credit quality of the commercial  loan portfolio
was  offset  by an  increase  in net  loans  charged-off  in the  consumer  loan
portfolio.  Net loans that were  charged-off  from indirect  automobile  lending
totaled $4.6 million in 2002  compared to $1.8 million in 2001.  The increase in
net  charge-offs of indirect  automobile  loans  reflected the effect of current
economic  conditions,   particularly  on  the  sub-prime  portion  of  the  loan
portfolio.   Increases  in  unemployment   rates  have  adversely  affected  the
borrowers' ability to repay their loans, while manufacturers'  incentives on new
vehicles  have created an  oversupply  of used  vehicles.  This  oversupply  has
reduced the value of collateral  securing these loans.  Net consumer  overdrafts
charged-off  increased from $814 thousand in 2001 to $2.2 million in 2002.  This
increase is primarily  related to the  introduction  of the overdraft  privilege
program previously  discussed in the other revenue section of this report. Table
16 presents  statistical  information  regarding the reserve for loan losses for
the past five years.

     Specific  reserves for  impairment  are  determined  through  evaluation of
estimated future cash flows and collateral  value. At December 31, 2002 specific
impairment reserves totaled $2 million on total impaired loans of $45 million.

     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 factor identified.  At December 31, 2002
the range of potential losses for the more significant factors were:

General economic conditions    -  $3.5 million - $4.3 million
Concentration of large loans   -  $900 thousand -$1.8 million
Loan portfolio growth          -  $475 thousand - $950 thousand

     Allocation  of the loan  loss  reserve  to the  major  loan  categories  is
presented  in Table 17. The increase in reserves  allocated to consumer  lending
reflected  the  increased  risk  associated  with the indirect  automobile  loan
portfolio and the consumer overdraft privilege program.

NONPERFORMING ASSETS

     Information  regarding  nonperforming  assets, which totaled $57 million at
December 31, 2002 and $51 million at December  31,  2001,  is presented in Table
18. Nonperforming assets included nonaccrual and renegotiated loans and excluded
loans 90 days or more past due but still  accruing  interest.  Nonaccrual  loans
increased  by $6.3 million  during  2002.  Newly  identified  nonaccruing  loans
totaled $38.1 million  during 2002.  This amount  included $14.7 million for one
borrower in the cattle industry. Management determined that it was probable that
all amounts due would not be recovered due to declining  cattle prices and other
factors unique to this borrower.  Nonaccruing  loans  decreased by $10.2 million
for  loans  restored  to  accruing   status  after  a  period  of   satisfactory
performance,  $9.3 million for charge-offs and foreclosures and $9.2 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 are not included in
Nonperforming Assets. Known information does, however,  cause management to have
concerns as to the borrowers'  ability to comply with current  repayment  terms.
Potential problem loans totaled $75 million at December 31, 2002 and $50 million
at December 31, 2001. At December 31, 2002, the composition of potential problem
loans by primary industry categories  included energy - $16 million,  recreation
property management - $14 million,  manufacturing - $13 million and healthcare -
$11 million.

DEPOSITS

     Average  deposits for 2002  increased $723 million or 11% compared to 2001.
Most  notably,  average  transaction  deposits  increased  $532  million  or 23%
compared to 2001 and was  attributable  to investor  fund growth.  The growth in
investor funds has been a result of increased sales training in consumer and the
depressed  equity  market.  Demand  deposits grew $83 million or 8% due to sales
initiatives  and training as well as strong product  development.  Time deposits
increased $97 million or 3%.

BORROWINGS AND CAPITAL

PARENT COMPANY

     BOK Financial  (parent  company) has a $122.5 million  unsecured  revolving
credit   agreement  with  certain  banks  that  matures  in  October  2004.  The
outstanding  principal balance of this credit agreement at December 31, 2002 was
$85  million.  Interest is based on either the London  Interbank  Offering  Rate
("LIBOR")  plus a defined  margin that is determined  by the  principal  balance
outstanding and BOK  Financial's  credit rating or a base rate. The base rate is
defined as the  greater of the daily  federal  funds rate plus 0.5% or the prime
rate. This credit agreement  includes certain  restrictive  covenants that limit
BOK Financial's  ability to borrow additional funds and to pay cash dividends on
common stock. These covenants also require BOK Financial and its subsidiaries to
maintain  minimum  capital  levels and to exceed  minimum net worth ratios.  BOK
Financial met all of the restrictive covenants at December 31, 2002.

     The primary sources of liquidity available to BOK Financial are earnings on
investments and dividends from subsidiaries. Dividends from subsidiary banks are
generally limited by various banking regulations to net profits, as defined, for
the year plus retained net profits for the  preceding  two years.  Dividends are
further restricted by minimum capital regulations. Based on the most restrictive
limitations,  BOK Financial's  subsidiary banks could declare up to $177 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 $125 million under this policy.

     During 2002,  BOK  Financial  issued  1,711,127  shares of common stock and
292,225  options to purchase  shares,  with a fair value at the issuance date of
$65 million for its purchase of Bank of Tanglewood.  In addition,  BOK Financial
agreed to a limited  price  guarantee on a portion of the shares  issued in this
purchase.  The fair value of this price  guarantee,  estimated  to be $3 million
based upon the  Black-Sholes  Option pricing model, was included in the purchase
price of Bank of  Tanglewood.  Pursuant  to this  guarantee,  any  holder of BOK
Financial common shares issued in this acquisition may annually make a claim for
the excess of the guaranteed price and the actual sales price of any shares sold
during a 60-day  period  after each of the first five  anniversary  dates  after
October 25, 2002.  The maximum annual number of shares subject to this guarantee
is 198,010.  The price guarantee is  non-transferable  and  non-cumulative.  BOK
Financial  may elect,  in its sole  discretion,  to issue  additional  shares of
common stock to satisfy any obligation under the price guarantee or to pay cash.
The maximum  aggregate number of common shares that may be issued to satisfy any
price  guarantee  obligations is 10 million.  If, as of any benchmark  date, BOK
Financial has already issued 10 million  shares,  BOK financial is not obligated
to make any further benchmark  payments.  BOK Financial's ability to pay cash to
satisfy any price  guarantee  obligations is limited by applicable  bank holding
company and bank capital and dividend regulations.

     The following  table  presents the  estimated  number of common shares that
would be required to be issued and the cash value equivalent if the market value
of BOK  Financial's  common  stock  remained  at $32.39,  its  closing  price on
December 31,  2002,  and if all holders  exercised  their rights under the price
guarantee agreement.

SUBSIDIARY BANKS

     BOK Financial's subsidiary banks use borrowings to supplement deposits as a
source of funds for loan and securities  growth.  These sources  include federal
funds purchased, securities repurchase agreements, and advances from the Federal
Home Loan Bank.  Interest  rates and maturity  dates for the various  sources of
funds  are  matched  with  specific  types  of  assets  in  the  asset/liability
management  process.  See Note 10 to the Consolidated  Financial  Statements for
additional  information  about the interest  rates and  maturity  dates of these
borrowings.

27

     In 1997,  BOk  issued  $150  million  of  7.125%  fixed  rate  subordinated
debentures  that mature in 2007.  Interest  rate swaps were used as a fair value
hedge to  convert  the  fixed  interest  on these  debentures  to a  LIBOR-based
floating  rate  requiring BOk to adjust the carrying  value of the  subordinated
debentures to fair value. In 2001, the interest rate swaps were terminated.  The
related market value adjustment of the subordinated  debentures of $8 million is
being recognized over the remaining life of the debt.

     Equity capital for BOK Financial  increased by $265 million to $1.1 billion
during 2002.  Retained  earnings  provided $150 million of this increase.  Other
comprehensive  income increased $37 million due primarily to the appreciation of
available  for sale  securities.  Securities  issued  in the Bank of  Tanglewood
acquisition increased shareholders' equity by $68 million. 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 a material  effect on  operations.  These  capital  requirements
include  quantitative  measures of assets,  liabilities  and  off-balance  sheet
items.  The capital  standards are also subject to qualitative  judgments by the
regulators.  The capital  ratios for BOK  Financial  and each of its  subsidiary
banks generally  increased  during 2002 as retained  capital was used to support
asset  growth.  See  Note  16  to  the  Consolidated  Financial  Statements  for
additional information regarding regulatory capital.

MARKET RISK

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

     BOK  Financial  is subject to market risk  primarily  through the effect of
changes  in  interest  rates on both its  assets  held for  purposes  other than
trading  and  trading  assets.  The  effects of other  changes,  such as foreign
exchange rates, commodity prices or equity prices do not pose significant market
risk to BOK Financial.  BOK Financial has no material investments in assets that
are  affected  by changes in foreign  exchange  rates or equity  prices.  Energy
derivative  contracts,  which are affected by changes in commodity  prices,  are
matched against offsetting contracts as previously discussed. Responsibility for
managing  market risk rests with the  Asset/Liability  Committee  that  operates
under policy  guidelines  established by the Board of Directors.  The acceptable
negative  variation in net  interest  revenue,  net income or economic  value of
equity due to a specified  basis point increase or decrease in interest rates is
generally  limited by these  guidelines to +/- 10%.  These  guidelines  also set
maximum levels for short-term  borrowings,  short-term assets, public funds, and
brokered  deposits,  and establish  minimum levels for unpledged  assets,  among
other things. Compliance with these guidelines is reviewed monthly.

INTEREST RATE RISK MANAGEMENT (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.  This combination  results in a balance
sheet that is  naturally  asset  sensitive.  Changes in  interest  rates  affect
earning assets more rapidly than interest bearing liabilities in the short term.
Management  has  adopted  several   strategies  to  reduce  this  interest  rate
sensitivity.  As previously  noted in the Net Interest  Revenue  section of this
report,  management  acquires  securities  that are funded by  borrowings in the
capital  markets.  These  securities have an average duration of approximately 2
years  while the related  funds  borrowed  have an average  duration of 90 days.
Average  securities  purchased and funds  borrowed under this strategy were $1.9
billion in 2002 compared to $1.7 billion in 2001.

     Additionally,  BOK  Financial  uses  interest  rate swaps in  managing  its
interest rate  sensitivity.  These  products are generally  used to more closely
match  interest  paid on  certain  fixed rate loans  with  funding  sources  and
long-term  certificates of deposits with earning  assets.  During 2002 and 2001,
net interest revenue increased by $12.7 million and $4.0 million,  respectively,
from the periodic  settlement  of these swaps.  Additionally,  net gains of $4.7
million  were  recognized  in  2002  compared  to net  losses  of  $3.4  million
recognized in 2001 from the adjustment to fair value of the interest rate swaps.
Credit risk from these swaps is closely  monitored and  counterparties  to these
contracts  are  factors.  Derivative  products  are  not  used  for  speculative
purposes.  See Note 4 to the  consolidated  Financial  Statements for additional
information.

     The effectiveness of these strategies in managing the overall interest rate
risk is evaluated  through the use of an  asset/liability  model.  BOK Financial
performs a  sensitivity  analysis to identify  more dynamic  interest  rate risk
exposures,  including  embedded option positions,  on net interest revenue,  net
income and economic value of equity.  A simulation model is used to estimate the
effect of changes in interest  rates over the next twelve  months based on eight
interest rate  scenarios.  Three  specified  interest rate scenarios are used to
evaluate interest rate risk against policy guidelines. These are a "most likely"
rate  scenario  and two "shock  test"  scenarios,  first  assuming  a  sustained
parallel 200 basis point increase and second  assuming a sustained  parallel 100
basis point  decrease  in  interest  rates.  Management  historically  evaluated
interest rate  sensitivity  for a sustained  200 basis point  decrease in rates.
However,  these results are not meaningful in the current low-rate  environment.
An  independent  source  is used to  determine  the most  likely  interest  rate
scenario.

     BOK  Financial's  primary  interest  rate  exposures  included  the Federal
Reserve Bank's targeted federal funds rate, which affects short-term borrowings,
and the  prime  lending  rate and  LIBOR,  which  are the  basis for much of the
variable-rate  loan pricing.  Additionally,  mortgage rates directly  affect the
prepayment speeds for mortgage-backed  securities and mortgage servicing rights.
Derivative  financial  instruments  and  other  financial  instruments  used for
purposes  other  than  trading  are  included  in  this  simulation.  The  model
incorporates  assumptions regarding the effects of changes in interest rates and
account balances on  indeterminable  maturity deposits based on a combination of
historical analysis and expected behavior.  The impact of planned growth and new
business  activities  is  factored  into the  simulation  model.  The effects of
changes in interest rates on the value of mortgage servicing rights are excluded
from Table 22 due to the extreme  volatility  over such a large rate range.  The
effects of interest rate changes on the value of mortgage  servicing  rights and
securities identified as economic hedges are shown in Table 23.

     As noted in the  Lines of  Business  -  Mortgage  Banking  section  of this
report,  BOK Financial has market risk associated with its portfolio of mortgage
servicing rights, primarily due to loan prepayments.  BOK Financial designates a
portion of its  securities  portfolio as an economic  hedge  against the risk of
loss on its  mortgage  servicing  rights.  Mortgage-backed  securities  and U.S.
government  agency  debentures  are acquired and held as available for sale when
prepayment risk exceeds certain  levels.  The fair value of these  securities is
expected to vary inversely to the fair value of the mortgage  servicing  rights.
This strategy  presents  certain risks. A well-developed  market  determines the
fair value for securities,  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 highly  correlate with
the change in value of the securities.

     At December 31, 2002,  securities  with a fair value of $129 million and an
unrealized  gain of $1.6  million were held for the  mortgage  servicing  rights
hedge  program.  This  unrealized  gain,  net of income  taxes,  is  included in
shareholders'  equity as part of other  comprehensive  income. 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 December 31, 2002,  the pre-tax
results of this modeling on reported earnings were:

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

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

     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  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 nominal  aggregate  trading positions to $100 million
and the VAR to $6.5 million. At December 31, 2002, the nominal aggregate trading
positions was $5.2 million and the VAR was $213 thousand.  The greatest value at
risk during 2002 was $1.7 million.

NEW ACCOUNTING STANDARDS

     During 2002,  the Financial  Accounting  Standards  Board  ("FASB")  issued
several  statements  and  interpretations   that  may  have  an  effect  on  BOK
Financial's accounting policies and financial reporting in future periods. These
included  Statements of Financial  Accounting  Standards  No. 146,  "Obligations
Associated with Disposal  Activities"  ("FAS 146") and No. 148,  "Accounting for
Stock-Based   Compensation  -  Transition  and   Disclosure"   ("FAS  148")  and
Interpretation No. 45, "Guarantor's  Accounting and Disclosure  Requirements for
Guarantees, Including Indirect Guarantees of Indebtedness of Others" ("FIN 45").

     FAS 146 addresses the  accounting and reporting for costs  associated  with
exit or disposal for Certain  Employee  Termination  Benefits and Other Costs to
Exit an Activity ("EITF 94-3"). Under the provisions of FAS 146, a liability for
costs  associated  with  an  exit  or  disposal  activity  should  be  initially
recognized  when it is incurred and  measured at fair value.  The main effect of
FAS 146  will be on the  timing  of  recognition  of such  costs.  They  will be
recognized as liabilities in periods following a commitment to a plan of exit or
disposal  rather than at the date of commitment as required under EITF 94-3. FAS
146 is not expected to have a significant impact on BOK Financial.

     FAS 148  provides  alternative  methods  of  transition  to the fair  value
accounting  method for  stock-based  employee  compensation  as required by FASB
Statement No. 123, "Accounting for Stock-Based Compensation ("FAS 123"). FAS 148
also amends the disclosure requirements of FAS 123 to include additional details
of the effects of FAS 123 on both annual and interim financial statements. These
additional disclosures are required regardless of whether a company accounts for
stock-based  compensation  using the fair value  method or the  intrinsic  value
method.  FAS 148 provides three transition  methods for companies that adopt the
fair value  accounting  method defined in FAS 123, the prospective  method,  the
retroactive   restatement  method  and  the  modified  prospective  method.  The
prospective method would apply to awards granted,  modified or settled after the
beginning of the fiscal year in which FAS 123 is first adopted.  This transition
method is only available if BOK Financial  adopts fair value accounting in 2003.
The  retroactive  restatement  method  requires  a  restatement  of all  periods
presented to reflect the fair value  accounting  method for all awards  granted,
modified  or settled  after  1994.  The  results of this  transition  method are
consistent  with the pro forma  disclosures  currently  required by FAS 123. The
modified  prospective method recognizes  compensation cost from the beginning of
the fiscal year in which the recognition  provisions are first adopted as if the
fair value method of accounting  had been used for awards  granted,  modified or
settled  after 1994.  This method  would affect  compensation  costs in the year
adopted but would not restate prior periods.  FAS 148 does not require  adoption
of the fair value method of accounting for stock-based  compensation provided by
FAS 123.

     FIN 45 requires  guarantees that meet certain  specified  definitions to be
initially  recorded  at fair  value  and  requires  expanded  disclosure  of all
guarantees by the guarantor. The recognition provisions of FIN 45 are applicable
to all guarantees  issued or modified  after December 31, 2002; the  disclosures
applicable  to  existing  guarantees  have  been  provided  in  Note  15 to  the
Consolidated Financial Statements. FIN 45, which will primarily be applicable to
standby  letters of credit issued by BOK  Financial's  subsidiary  banks, is not
expected to have a material effect on the results of operations.

FORWARD-LOOKING STATEMENTS

     This Annual 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.

REPORT OF MANAGEMENT ON FINANCIAL STATEMENTS

     Management is responsible for the consolidated financial statements,  which
have been prepared in accordance with accounting  principles  generally accepted
in the United States.  In management's  opinion,  the accompanying  consolidated
financial  statements  contain all adjustments  (consisting of normal  recurring
accruals)  necessary  to present  fairly the  financial  conditions,  results of
operations and cash flows of BOK Financial and its subsidiaries at the dates and
for the periods presented.

     As of December 31, 2002, an evaluation was performed  under the supervision
and with the  participation of BOK Financial's  management,  including the Chief
Executive  Officer (CEO) and Chief Financial Officer (CFO), of the effectiveness
of  the  design  and  operation  of  BOK  Financial's  disclosure  controls  and
procedures. Based on that evaluation, BOK Financial's management,  including the
CEO and CFO, concluded that BOK Financial's  disclosure  controls and procedures
were effective as of December 31, 2002.  There have been no significant  changes
in  BOK   Financial's   internal   controls  or  in  other  factors  that  could
significantly affect internal controls subsequent to December 31, 2002.

     BOK Financial and its subsidiaries maintain a system of internal accounting
controls designed to provide reasonable assurance that transactions are executed
in  accordance  with  management's  general or specific  authorization,  and are
recorded  as  necessary  to  maintain  accountability  for  assets and to permit
preparation of financial  statements in accordance  with  accounting  principles
generally  accepted in the United States.  This system includes written policies
and  procedures,  a corporate  code of conduct,  an internal  audit  program and
standards for the hiring and training of qualified personnel.

     The Board of  Directors of BOK  Financial  maintains a Risk  Oversight  and
Audit  Committee  consisting of outside  directors that meet  periodically  with
management and BOK Financial's internal and independent auditors.  The Committee
considers  the audit and nonaudit  services to be  performed by the  independent
auditors,  makes  arrangements  for the  internal  and  independent  audits  and
recommends BOK Financial's selection of independent auditors. The Committee also
reviews the results of the internal and independent audits,  critical accounting
policies and practices,  and various  shareholder  reports and other reports and
filings.

     Ernst & Young LLP, certified public accountants, have been engaged to audit
the  consolidated  financial  statements of BOK Financial and its  subsidiaries.
Their  audit is  conducted  in  accordance  with  auditing  standards  generally
accepted in the United States and their report on BOK  Financial's  consolidated
financial statements is set forth below.

REPORT OF INDEPENDENT AUDITORS

     We  have  audited  the  accompanying  consolidated  balance  sheets  of BOK
Financial  Corporation  as of  December  31,  2002  and  2001,  and the  related
consolidated  statements of earnings,  changes in shareholders' equity, and cash
flows for each of the three years in the period ended  December 31, 2002.  These
financial  statements are the  responsibility of the Company's  management.  Our
responsibility  is to express an opinion on these financial  statements based on
our audits.

     We conducted our audits in accordance  with  auditing  standards  generally
accepted in the United States.  Those standards require that we plan and perform
the audit to obtain reasonable  assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements.  An
audit also includes  assessing the accounting  principles  used and  significant
estimates  made by  management,  as well as  evaluating  the  overall  financial
statement  presentation.  We believe that our audits provide a reasonable  basis
for our opinion.

     In our opinion,  the financial statements referred to above present fairly,
in all material respects,  the consolidated  financial position of BOK Financial
Corporation at December 31, 2002 and 2001, and the  consolidated  results of its
operations  and its cash flows for each of the three  years in the period  ended
December 31,  2002, in conformity with accounting  principles generally accepted
in the United States.

     As discussed in Note 1 to the consolidated financial statements,  effective
January 1, 2002, the Company adopted Statement of Financial Accounting Standards
No. 142, Goodwill and Other Intangible Assets.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(1) SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

     The Consolidated  Financial  Statements of BOK Financial  Corporation ("BOK
Financial")  have  been  prepared  in  conformity  with  accounting   principles
generally  accepted in the United  States,  including  general  practices of the
banking industry.  The consolidated financial statements include the 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.  and  BOSC,  Inc.  Certain  prior  year  amounts  have  been
reclassified to conform to current year classifications.

NATURE OF OPERATIONS

     BOK Financial, through its subsidiaries, provides a wide range of financial
services to commercial and industrial  customers,  other financial  institutions
and consumers throughout Oklahoma, Northwest Arkansas, Dallas and Houston, Texas
metropolitan  areas and New Mexico.  These services include  depository and cash
management; lending and lease financing; mortgage banking; securities brokerage,
trading and underwriting; and personal and corporate trust.

USE OF ESTIMATES

     Preparation of BOK Financial's  consolidated  financial statements requires
management to make estimates of future economic  activities,  including interest
rates,  loan  collectibility  and  prepayments  and  cash  flows  from  customer
accounts.  These  estimates are based upon current  conditions  and  information
available to  management.  Actual  results may differ  significantly  from these
estimates.

ACQUISITIONS

     Assets and liabilities  acquired by purchase are recorded at fair values on
the  acquisition  dates.  The  Consolidated  Statements of Earnings  include the
results of purchases from the dates of acquisition.

INTANGIBLE ASSETS

     BOK Financial adopted Statements of Financial Accounting Standards No. 142,
"Goodwill and Other Intangible Assets" ("FAS 142") and No. 147, "Acquisitions of
Certain  Financial  Institutions"  ("FAS 147") on January 1, 2002. The following
table  presents  the impact on  previously  reported net income and earnings per
share after application of FAS 142 and FAS 147:

                                   2001          2000
                               ------------- -------------
Net income previously
   reported                    $ 116,302     $ 100,140
Pro forma net income             125,464       105,282
Diluted earnings per share
   previously reported             $1.95         $1.69
Pro forma diluted earnings
   per share                        2.10          1.78


     Intangible assets with indefinite  lives,  such as goodwill,  are no longer
amortized and must be evaluated for each of BOK  Financial's  business units for
impairment  at  least  annually  or  more  frequently  if  conditions   indicate
impairment.  The evaluation of possible impairment of intangible assets involves
significant  judgment based upon short-term and long-term  projections of future
performance.

     The fair  value of BOK  Financial's  business  units  is  estimated  by the
discounted  future earnings method.  Income growth is projected over a five-year
period for each unit and a terminal  value is computed.  This  projected  income
stream is converted to current fair value by using a discount rate that reflects
a rate of return required by a willing buyer.

     Other  identifiable  intangible  assets and core  deposit  intangibles  are
amortized using straight-line and accelerated methods over the estimated benefit
periods. These periods range from 5-7 years for other intangible assets and core
deposit  intangibles.  The net book value of these  other  intangibles  and core
deposit  intangibles  are evaluated  for  impairment  when  economic  conditions
indicate an impairment may exist.

CASH EQUIVALENTS

     Due from  banks,  funds sold  (generally  federal  funds  sold for  one-day
periods) and resell  agreements  (which  generally mature within one to 30 days)
are considered cash equivalents.

SECURITIES

     Securities  are  identified  as trading,  investment  (held to maturity) or
available for sale at the time of purchase  based upon the intent of management,
liquidity and capital  requirements,  regulatory  limitations and other relevant
factors.  Trading securities,  which are acquired for profit through resale, are
carried at market  value with  unrealized  gains and losses  included in current
period   earnings.   Investment   securities  are  carried  at  amortized  cost.
Amortization is computed by methods that approximate level yield and is adjusted
for  changes  in  prepayment  estimates.  Investment  securities  may be sold or
transferred to trading or available for sale  classification  in certain limited
circumstances specified in generally accepted accounting principles.  Securities
identified as available for sale are carried at fair value. Unrealized gains and
losses  are  recorded,  net of  deferred  income  taxes,  as  accumulated  other
comprehensive income (loss) in shareholders'  equity.  Realized gains and losses
on  sales of  securities  are  based  upon the  amortized  cost of the  specific
security  sold.  Available  for sale  securities  are  separately  identified as
pledged to  creditors  if the  creditor  has the right to sell or  repledge  the
collateral.

     The purchase or sale of securities  is recognized on a trade date basis.  A
net receivable or payable is recognized for subsequent  transaction  settlement.
BOK  Financial  will  periodically  commit to purchase  or sell  to-be-announced
("TBA") mortgage-backed  securities.  These commitments are not reflected in BOK
Financial's  balance  sheet  until  settlement  date,  in  accordance  with  the
accounting guidance of the Comptroller of the Currency. However, any losses from
TBA securities sales are recognized as of the commitment date.

DERIVATIVE INSTRUMENTS

     Derivative  instruments,  primarily  interest  rate swaps and forward sales
contracts,  are  used as part of an  interest  rate  risk  management  strategy.
Interest rate swaps modify the interest income and expense on certain long-term,
fixed rate assets and  liabilities.  Amounts  payable to or receivable  from the
counterparties  are  reported in interest  income and expense  using the accrual
method. The fair value of the interest rate swaps is included in other assets or
liabilities.  Changes in the fair value of interest  rate swaps are  included in
other operating revenue.

     In certain  circumstances,  interest  rate swaps may be  designated as fair
value hedges and may qualify for hedge accounting.  Changes in the fair value of
the hedged  asset or  liability  that are  attributable  to the hedged  risk are
reported in other operating  revenue.  These changes may partially or completely
offset the  mark-to-market  adjustments  of the interest rate swaps.  Fair value
hedges are considered to be effective if the cumulative  fair value  adjustments
of the interest  rate swaps are within a range of 80% to 120% of the  cumulative
fair value adjustment of the hedged assets or liabilities.

     Interest  rate swaps may be designated as cash flow hedges of variable rate
assets or  liabilities  or  anticipated  transactions.  Changes in fair value of
interest  rate swaps are  recorded in other  comprehensive  income to the extent
they  are  effective.   Amounts  recorded  as  other  comprehensive  income  are
recognized  in net income in the same  periods as the cash flows from the hedged
transactions.

     In conjunction with its mortgage banking  activities,  BOK Financial enters
into mortgage loan commitments that are considered derivative  instruments under
FAS  133.  Forward  sales  contracts  are  used to  hedge  these  mortgage  loan
commitments  and mortgage loans held for sale.  Changes in the fair value of the
mortgage loan  commitments  and forward sales  contracts are recognized in other
operating revenue.

     Energy contracts are used to assist certain customers in hedging their risk
of adverse  changes in natural gas and oil prices.  BOK  Financial  serves as an
intermediary  between  its  energy  customers  and  the  commodities  market  by
arranging  fixed  price/floating  price  contracts.  Each  contract  between BOK
Financial  and its customer is offset by a contract  between BOK  Financial  and
dealers in the commodities market. The fair value of these contracts are carried
in  other  assets  and  other  liabilities.  Compensation  for  credit  risk and
reimbursement  of  administrative  costs  are  recognized  over  the life of the
contracts.

LOANS

     Loans are  either  secured or  unsecured  based on the type of loan and the
financial  condition of the borrower.  Repayment is generally expected from cash
flow or proceeds from the sale of selected assets of the borrower. BOK Financial
is exposed to risk of loss on loans due to the  borrower's  difficulties,  which
may arise from any number of factors,  including  problems within the respective
industry or local economic  conditions.  Access to  collateral,  in the event of
borrower default,  is reasonably assured through adherence to applicable lending
laws and through sound lending standards and credit review procedures.

     Interest is accrued at the applicable interest rate on the principal amount
outstanding.  Loans are placed on  nonaccrual  status  when,  in the  opinion of
management,  full  collection of principal or interest is  uncertain,  generally
when the  collection  of  principal  or  interest  is 90 days or more  past due.
Interest previously accrued but not collected is charged against interest income
when the loan is placed on nonaccrual  status.  Payments on nonaccrual loans are
applied to principal or reported as interest  income,  according to management's
judgment as to the collectibility of principal.

     Loan  origination  and  commitment  fees and direct  loan  acquisition  and
origination costs, when significant, are deferred and amortized as an adjustment
to yield over the life of the loan or over the commitment period, as applicable.

     Mortgage  loans held for sale are carried at the lower of aggregate cost or
market value,  including  estimated losses on unfunded  commitments and gains or
losses on related  forward  sales  contracts.  Effective  with the  adoption  of
FAS 133,  mortgage  loans held for sale that are designated as hedged assets are
carried at fair value based on sales  commitments or market  quotes.  Changes in
fair value after the date of designation  of an effective  hedge are recorded in
other operating revenue.

RESERVE FOR LOAN LOSSES

     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,  and includes  probable  losses on both  outstanding
loans and unused commitments to provide financing.  A consistent methodology has
been developed that includes  reserves  assigned to specific  criticized  loans,
general  reserves that are based upon  statistical  migration  analyses for each
category of loans, and a nonspecific allowance that is based upon an analysis of
current economic  conditions,  loan  concentrations,  portfolio growth and other
relevant  factors.  The  reserve  for loan  losses  related  to  loans  that are
identified for evaluation in accordance  with Statement of Financial  Accounting
Standards  No.  114,   "Accounting  by  Creditors  for  Impairment  of  a  Loan"
("FAS 114"),  is based  on  discounted  cash  flows  using  the  loan's  initial
effective  interest  rate  or the  fair  value  of the  collateral  for  certain
collateral  dependent loans. Loans are considered to be impaired when it becomes
probable that BOK Financial  will be unable to collect all amounts due according
to the contractual  terms of the loan agreement.  This is substantially the same
criteria used to determine  when a loan should be placed on  nonaccrual  status.
This  evaluation is  inherently  subjective  as it requires  material  estimates
including the amounts and timing of future cash flows expected to be received on
impaired loans that may be susceptible to significant change.

     In accordance with the provisions of FAS 114, management has excluded small
balance,  homogeneous loans from the impairment evaluation specified in FAS 114.
Such loans include 1-4 family  mortgage loans,  consumer  loans,  and commercial
loans with committed  amounts less than $1 million.  The adequacy of the reserve
for loan  losses  applicable  to these loans is  evaluated  in  accordance  with
generally  accepted  accounting  principles  and  standards  established  by the
banking regulatory authorities and adopted as policy by BOK Financial.

     A  provision  for loan  losses  is  charged  against  earnings  in  amounts
necessary to maintain an adequate reserve for loan losses. Loans are charged off
when the loan balance or a portion of the loan  balance is no longer  covered by
the paying  capacity of the borrower  based on an evaluation  of available  cash
resources and collateral  value.  Loans are evaluated  quarterly and charge-offs
are taken in the  quarter  in which the loss is  identified.  Additionally,  all
unsecured  or  under-secured  loans  that  are  past due by 180 days or more are
charged off within 30 days. Recoveries of loans previously charged off are added
to the reserve.

ASSET SECURITIZATION

     BOK Financial  periodically  securitizes  and sells pools of assets.  These
transactions  are recorded as sales for  financial  reporting  purposes when the
criteria for surrender of control specified in Statement of Financial Accounting
Standards,  No. 140 "Accounting for Transfers and Servicing of Financial  Assets
and  Extinguishment  of Liabilities" are met. BOK Financial may retain the right
to service the assets and a residual  interest in excess cash flows generated by
the  assets.  The  carrying  value of the assets sold is  allocated  between the
portion sold and the portion  retained  based on relative fair values.  The fair
value of these retained assets is determined by a discounting of expected future
net  cash  to  be  received  using  assumed  market  interest  rates  for  these
instruments.  Residual  interests  are  carried at fair  value.  Changes in fair
values are  recorded  in income.  Servicing  rights are  carried at the lower of
amortized cost or fair value.  A valuation  allowance is provided when amortized
cost of servicing rights exceeds fair value.

38

REAL ESTATE AND OTHER REPOSSESSED ASSETS

     Real estate and other repossessed  assets are assets acquired in partial or
total  forgiveness of debt. These assets are carried at the lower of cost, which
is  determined  by fair value at date of  foreclosure,  or current  fair  value.
Income  generated  by these assets is  recognized  as  received,  and  operating
expenses are recognized as incurred.

PREMISES AND EQUIPMENT

     Premises and equipment are carried at cost including  capitalized interest,
when appropriate,  less accumulated depreciation and amortization.  Depreciation
and amortization are computed on a straight-line basis over the estimated useful
lives of the assets  or, for  leasehold  improvements,  over the  shorter of the
estimated  useful lives or remaining lease terms.  Repair and maintenance  costs
are charged to expense as incurred.

MORTGAGE SERVICING RIGHTS

     Capitalized mortgage servicing rights are carried at the lower of amortized
cost, adjusted for the effect of hedging activities, or fair value. Amortization
is determined in proportion to the projected cash flows over the estimated lives
of the  servicing  portfolios.  The  actual  cash flows are  dependent  upon the
prepayment  of  the  mortgage  loans  and  may  differ  significantly  from  the
estimates.

     Fair  value is  determined  by  discounting  the  estimated  cash  flows of
servicing revenue,  less projected servicing costs, using  risk-adjusted  rates,
which is the assumed market rate for these instruments.  Prepayment  assumptions
were based on industry  consensus  provided by independent  reporting sources in
2001 and 2000.  During  2002,  BOK  Financial  changed the source of  prepayment
assumptions  used to value its mortgage  servicing  rights.  Industry  consensus
prepayment speeds were not updated frequently enough to reflect rapidly changing
market  conditions that existed in 2002. A separate,  third-party  model that is
generally  accepted by the financial markets is now used to estimate  prepayment
speeds. This model is updated daily for changes in market conditions. Changes in
current interest rates may  significantly  affect these  assumptions by changing
loan  refinancing  activity.  Amortized  cost and fair value are  stratified  by
interest  rate and loan type.  A valuation  allowance  is provided  when the net
amortized cost of any strata exceeds the calculated fair value.

     Originated  mortgage  servicing  rights are recognized when either mortgage
loans are  originated  pursuant to an existing plan for sale or, if no such plan
exists, when the mortgage loans are sold.  Substantially all fixed rate mortgage
loans originated by BOK Financial are sold under existing commitments. The right
to service  mortgage  loans sold is  generally  retained.  The fair value of the
originated  servicing  rights is determined at closing based upon current market
rates.

HEDGING OF MORTGAGE SERVICING RIGHTS

     During 1998 through the first quarter of 2000,  BOK Financial  entered into
futures contracts and call and put options on futures contracts to hedge against
the  risk  of  loss  on  mortgage  servicing  rights  due  to  accelerated  loan
prepayments  during periods of falling  interest rates.  Contracts on underlying
securities  that  were  expected  to have a  similar  duration  to the  mortgage
servicing  portfolio,  such as ten-year U.S. Treasury notes, were used for these
hedges.  The  combination  of contracts  selected was expected to achieve a high
degree  of  correlation  between  changes  in the  fair  value  of the  mortgage
servicing  rights  and  changes  in the  market  value of the  contracts.  These
contracts  were  designated  as hedges on the trade date.  Both  unrealized  and
realized  gains and  losses on  futures  contracts  and  option  contracts  were
deferred as part of the capitalized  mortgage  servicing rights.  These deferred
gains and losses are  amortized  over the estimated  life of the loan  servicing
portfolio.  This derivatives-based hedging program was discontinued in 2000. BOK
Financial  currently  acquires  mortgage-backed  securities and U.S.  government
agency debentures when the prepayment risk exceeds certain levels to serve as an
economic hedge against  changes in value of its portfolio of mortgage  servicing
rights.  The fair value of these securities is expected to vary inversely to the
value of the mortgage  servicing  rights.  These  securities  are  classified as
available  for sale  and  carried  at fair  value.  Changes  in fair  value  are
recorded,  net of deferred  income  taxes,  as other  accumulated  comprehensive
income (loss) in shareholders' equity.  Management may sell these securities and
recognize  gains  when  necessary  to offset  losses on the  mortgage  servicing
rights.

FEDERAL AND STATE INCOME TAXES

     BOK Financial utilizes the liability method in accounting for income taxes.
Under this method, deferred tax assets and liabilities are determined based upon
the difference  between the values of the assets and liabilities as reflected in
the  financial  statement and their related tax basis using enacted tax rates in
effect for the year in which the  differences  are  expected to be  recovered or
settled.  As changes in tax law or rates are  enacted,  deferred  tax assets and
liabilities are adjusted through the provision for income taxes.

     BOK Financial  and its  subsidiaries  file  consolidated  tax returns.  The
subsidiaries  provide for income taxes on a separate return basis,  and remit to
BOK Financial amounts determined to be currently payable.

EMPLOYEE BENEFIT PLANS

     BOK Financial  sponsors various plans,  including a defined benefit pension
plan ("Pension  Plan"),  qualified  profit sharing plans ("Thrift  Plans"),  and
employee  healthcare plans.  Employer  contributions to the Thrift Plans,  which
match employee  contributions subject to percentage and years of service limits,
are expensed when incurred.  Pension Plan costs,  which are based upon actuarial
computations of current costs, are expensed annually. Unrecognized prior service
cost and net gains or losses are  amortized  on a  straight-line  basis over the
estimated  remaining  lives of the  participants.  BOK Financial  recognizes the
expense of health care benefits on the accrual method. Employer contributions to
the Pension Plan and various  health care plans are in  accordance  with Federal
income tax regulations.

EXECUTIVE BENEFIT PLANS

     BOK Financial has elected to follow Accounting Principles Board Opinion No.
25,  "Accounting  for  Stock  Issued  to  Employees,"  ("APB  25")  and  related
interpretations  in accounting  for its employee  stock  options.  Under APB 25,
because the exercise  price of employee stock options equals the market price of
the underlying  stock options on the date of grant, no  compensation  expense is
recorded. BOK Financial has adopted the disclosure-only  provisions of Statement
of  Financial   Accounting   Standards  No.  123,  "Accounting  for  Stock-Based
Compensation,"  ("FAS 123"),  as amended by Statements  of Financial  Accounting
Standards No. 148,  "Accounting  for  Stock-Based  Compensation - Transition and
Disclosure" ("FAS 148").

     The  following  table  represents  the required pro forma  disclosures  for
options granted subsequent to December 31, 1994 (in thousands,  except per share
data):

     1    Because Statement 123 is applicable only to options granted subsequent
          to December 31, 1994, its pro forma effect will not be fully reflected
          until 2003.

FIDUCIARY SERVICES

     Fees and commissions on approximately  $17 billion of assets managed by BOK
Financial  under various  fiduciary  arrangements  are recognized on the accrual
method.

EFFECT OF PENDING STATEMENTS OF FINANCIAL ACCOUNTING STANDARDS

     During 2002,  the Financial  Accounting  Standards  Board  ("FASB")  issued
several  statements  and  interpretations   that  may  have  an  effect  on  BOK
Financial's accounting policies and financial reporting in future periods. These
included  Statements of Financial  Accounting  Standards  No. 146,  "Obligations
Associated with Disposal  Activities" ("FAS 146") and FAS 148 and Interpretation
No. 45,  "Guarantor's  Accounting and Disclosure  Requirements  for  Guarantees,
Including Indirect Guarantees of Indebtedness of Others" ("FIN 45").

     FAS 146 addresses the  accounting and reporting for costs  associated  with
exit or disposal for Certain  Employee  Termination  Benefits and Other Costs to
Exit an Activity ("EITF 94-3"). Under the provisions of FAS 146, a liability for
costs  associated  with  an  exit  or  disposal  activity  should  be  initially
recognized  when it is incurred and  measured at fair value.  The main effect of
FAS 146  will be on the  timing  of  recognition  of such  costs.  They  will be
recognized as liabilities in periods following a commitment to a plan of exit or
disposal  rather than at the date of commitment as required under EITF 94-3. FAS
146 is not expected to have a significant impact on BOK Financial.

     FAS 148  provides  alternative  methods  of  transition  to the fair  value
accounting method for stock-based employee  compensation as required by FAS 123.
FAS 148 also amends the disclosure requirements of FAS 123 to include additional
details  of the  effects  of FAS  123  on  both  annual  and  interim  financial
statements.  These additional  disclosures are required  regardless of whether a
company accounts for stock-based compensation using the fair value method or the
intrinsic value method.  FAS 148 provides three transition methods for companies
that adopt the fair value accounting  method defined in FAS 123, the prospective
method, the retroactive  restatement method and the modified prospective method.
The prospective method would apply to awards granted,  modified or settled after
the  beginning  of the  fiscal  year in  which  FAS 123 is first  adopted.  This
transition  method  is  only  available  if  BOK  Financial  adopts  fair  value
accounting in 2003. The retroactive restatement method requires a restatement of
all periods presented to reflect the fair value accounting method for all awards
granted,  modified or settled after 1994. The results of this transition  method
are consistent with the pro forma disclosures currently required by FAS 123. The
modified  prospective method recognizes  compensation cost from the beginning of
the fiscal year in which the recognition  provisions are first adopted as if the
fair value method of accounting  had been used for awards  granted,  modified or
settled  after 1994.  This method  would affect  compensation  costs in the year
adopted,  but would not restate prior periods. FAS 148 does not require adoption
of the fair value method of accounting for stock-based  compensation provided by
FAS 123.

     FIN 45 requires  guarantees that meet certain  specified  definitions to be
initially  recorded  at fair  value  and  requires  expanded  disclosure  of all
guarantees.  The  recognition  provisions  of  FIN  45  are  applicable  to  all
guarantees   issued  or  modified  after  December  31,  2002;  the  disclosures
applicable  to  existing  guarantees  have  been  provided  in  Note  15 to  the
Consolidated Financial Statements. FIN 45, which will primarily be applicable to
standby  letters of credit issued by BOK  Financial's  subsidiary  banks, is not
expected to have a material effect on the results of operations.

(2) ACQUISITIONS

     On October 25, 2002, BOK Financial  acquired Bank of  Tanglewood,  N.A. for
1,711,127 shares of common stock and 292,225 options to purchase shares,  valued
at approximately  $65 million.  The options to purchase shares were issued at an
average  exercise price of $7.73 and expire February 25, 2003. In addition,  BOK
Financial  agreed to a price  guarantee  on 50 percent of the stock issued under
this agreement. The price guarantee resulted in a contingent obligation to issue
additional   shares  or  cash  over  the  next  five  years   based  on  certain
predetermined market valuations of its common stock. The value of the contingent
price guarantee based on the Black-Scholes Option Pricing Model, was $3 million,
which  was  included  in the  total  purchase  price.  More  discussion  of this
contingency is at Note 16.

     On January  11,  2001,  BOK  Financial  paid $91  million  to  acquire  all
outstanding  common shares of CNBT Bancshares,  Inc. and its subsidiary  Citizen
National Bank of Texas in Houston (collectively "CNBT").

     These transactions were accounted for by the purchase method of accounting.

FORWARD SALES CONTRACTS

     BOK Financial uses  mortgage-backed  securities  forward sales contracts to
manage  exposure to interest rate  fluctuations  on mortgage loans held for sale
and mortgage  loan  commitments.  At December 31, 2002,  the notional  amount of
forward sales contracts totaled $178 million, with a negative fair value of $2.1
million. Additional discussion of these contracts can be found in Note 8.

ENERGY DERIVATIVES

     BOK Financial manages a program that permits its energy-producing customers
to hedge against price fluctuations and take positions through energy option and
swap  contracts.  These  contracts are executed  between BOk and its  customers.
Offsetting  contracts are executed between BOk and selected energy dealers.  The
dealer  contracts  are identical to the customer  contracts,  except for a fixed
pricing spread paid to BOk as compensation for administrative costs, credit risk
and profit.  This program  creates credit risk for potential  amounts due to BOk
from the  customers  and  dealers.  Customer  credit risk is  monitored  through
existing  lending  policies and  procedures.  The value of energy  production is
evaluated  across a range of  prices to  determine  a  maximum  exposure  BOk is
willing  to accept  individually  to any one  customer.  Dealer  credit  risk is
monitored through existing policies and procedures used to evaluate counterparty
risk. This evaluation considers all relationships between BOK Financial and each
counterparty.  Individual  limits are  established by management and approved by
the Risk Oversight Committee of the Board of Directors.

     BOK  Financial  carries the energy  contracts at fair value in other assets
and other liabilities.  At December 31,  2002, other assets included $71 million
and other liabilities included $71 million of energy contracts.  At December 31,
2001,  other  assets  included  $28 million and other  liabilities  included $29
million  of energy  contracts.  Changes in fair  value are  recorded  in income.
Closing prices on the New York Mercantile Exchange and values provided by energy
dealers are used as the basis to determine  fair values of  contracts  with both
dealers.

     The  majority  of  the   commercial   and  consumer  loan   portfolios  and
approximately  74% of the residential  mortgage loan portfolio  (excluding loans
held for  sale)  are loans to  businesses  and  individuals  in  Oklahoma.  This
geographic  concentration  subjects the loan  portfolio to the general  economic
conditions within this area.

     Within  the  commercial  loan   classification,   loans  to  energy-related
businesses  total $1.1 billion,  or 16% of total loans.  Other notable  segments
include   wholesale/retail,   $627   million;   manufacturing,   $502   million;
agriculture,  $187  million,  which  includes  $163 million  loans to the cattle
industry;  and  services,  $1.2  billion,  which  include  nursing homes of $218
million, hotels of $68 million and healthcare of $114 million.

     Approximately 43% of commercial real estate loans are secured by properties
located in Oklahoma, primarily in the Tulsa or Oklahoma City metropolitan areas.
An  additional  30% of  commercial  real  estate  loans are  secured by property
located in Texas.  The major  components  of these  properties  are  multifamily
residences,  $307 million;  construction  and  land  development,  $356 million;
retail facilities, $195 million; and office buildings, $292 million.

(8) MORTGAGE BANKING ACTIVITIES

     BOK  Financial  engages in  mortgage  banking  activities  through  the BOk
Mortgage Division of BOk.  Residential mortgage loans held for sale totaled $133
million and $166 million and outstanding  mortgage loan commitments totaled $323
million and $261 million at December 31, 2002 and 2001,  respectively.  Mortgage
loan commitments are generally  outstanding for 60 to 90 days and are subject to
both credit and interest rate risk. Credit risk is managed through  underwriting
policies and procedures,  including collateral requirements, which are generally
accepted by the secondary loan markets.  Exposure to interest rate  fluctuations
is partially hedged through the use of mortgage-backed  securities forward sales
contracts. These contracts set the price for loans that will be delivered in the
next 60 to 90 days.

     At December 31, 2002, BOk owned the rights to service 76,298 mortgage loans
with  outstanding  principal  balances of $5.8 billion,  including  $358 million
serviced  for BOk,  and held related  funds of $174  million for  investors  and
borrowers.  The weighted  average interest rate and remaining term was 7.05% and
265 months, respectively. Mortgage loans sold with recourse totaled $1.8 million
at  December 31,  2002.  At December 31,  2001,  BOk owned the rights to service
88,916 mortgage loans with  outstanding  principal  balances of $6.6 billion and
held related  funds of $177 million for investors  and  borrowers.  The weighted
average interest rate and remaining term was 7.30% and 266 months, respectively.

     The  portfolio of mortgage  servicing  rights  exposes BOk to interest rate
risk.  During  periods of falling  interest  rates,  mortgage  loan  prepayments
increase,  reducing the value of the mortgage  servicing rights.  See Note 1 for
specific  accounting  policies  for  mortgage  servicing  rights and the related
hedges.

     Discount rate - Risk adjusted rates by loan product,  ranging from 8.88% to
22.00%.

     Prepayment rate - Annual prepayment estimates ranging from 24.78% to 68.07%
based upon loan interest rate, original term and loan type.

     Loan servicing costs - $35 to $50 annually per loan based upon loan type.

banks at December  31, 2002 of $122.5  million.  Interest is based on either the
London  Interbank  Offering  Rate  ("LIBOR")  plus  a  defined  margin  that  is
determined by the  principal  balance  outstanding  and BOK  Financial's  credit
rating or a base  rate.  The base rate is  defined  as the  greater of the daily
federal  funds rate plus 0.5% or the prime  rate.  Interest  is paid  quarterly.
Facility fees are paid  quarterly on the average  daily undrawn  commitment at a
rate of 0.20% - 0.30% as determined by BOK Financial's current debt rating. This
credit  agreement  includes  certain   restrictive   covenants  that  limit  BOK
Financial's  ability to borrow  additional  funds and to pay cash  dividends  on
common stock. These covenants also require BOK Financial and its subsidiaries to
maintain  minimum  capital  levels and to exceed  minimum net worth ratios.  BOK
Financial met all of the restrictive covenants at December 31, 2002.

     In 1997,  BOk  issued  $150  million  of  7.125%  fixed  rate  subordinated
debentures  that mature in 2007.  Interest  rate swaps were used as a fair value
hedge to  convert  the  fixed  interest  on these  debentures  to a  LIBOR-based
floating  rate.   This  required  BOk  to  adjust  the  carrying  value  of  the
subordinated  debentures  to fair value.  In 2001,  the interest rate swaps were
terminated. The related market value adjustment of the subordinated debenture of
$8 million is being recognized over the remaining life of the debt.

     BOK  Financial  issued a $30 million,  seven year  subordinated  debenture,
bearing  interest  at LIBOR  plus  1.75%,  on March  23,  2001 to its  principal
shareholder George B. Kaiser ("Kaiser").  This debt was paid off in its entirety
in November 2002.

     Funds  purchased  generally  mature  within  one to  ninety  days  from the
transaction  date.  At December 31, 2002,  securities  sold under  agreements to
repurchase  totaled $1.0 billion with related accrued  interest  payable of $473
thousand.  Additional  information relating to repurchase agreements at December

     The Internal  Revenue  Service  closed its  examination  of 1996 during the
first  quarter  of 2000.  As a result of the  outcome of this  examination,  BOK
Financial  reduced its federal  income tax expense by $3.0 million in 2000.  The
Internal  Revenue Service is currently  examining the carryback of $30.8 million
of capital loss generated in 1999.  Such loss was applied  against capital gains
generated  in 1997 and 1998,  resulting  in a $9.8  million  refund.  Management
expects no material  adverse  impact on the financial  statements as a result of
this examination.

     Assets of the Pension Plan consist  primarily of shares in cash  management
funds,  common stock and bond funds, and guaranteed  investment  contract funds.
Benefits are based on the employee's age and length of service.

     Employee  contributions to the Thrift Plans are matched by BOK Financial up
to 5% of base compensation, based upon years of service. Participants may direct
the  investments  of their  accounts  in a variety  of  options,  including  BOK
Financial Common Stock.  Employer  contributions vest over five years.  Expenses
incurred by BOK  Financial  for the Thrift  Plans  totaled  $3.1  million,  $2.8
million and $2.3 million for 2002, 2001 and 2000, respectively.

     BOK Financial  also  sponsors a defined  benefit  post-retirement  employee
medical plan,  which pays 50 percent of annual  medical  insurance  premiums for
retirees  who meet certain age and service  requirements.  Assets of the retiree
medical plan consist primarily of shares in a cash management fund.  Eligibility
for  the  post-retirement  plan is  limited  to  current  retirees  and  certain
employees currently age 60 or older at the time the plan was frozen in 1993.

     Under various performance incentive plans,  participating  employees may be
granted  awards  based on defined  formulas  or other  criteria.  Earnings  were
charged $32.1 million in 2002, $27.2 million in 2001, and $22.2 million in 2000,
for such awards.

(13) EXECUTIVE BENEFIT PLANS

     The Board of Directors of BOK Financial  has approved  various stock option
plans.  The number of options  awarded and the  employees to receive the options
are  determined  by the Chairman of the Board and the Chief  Executive  Officer,
subject to approval of the Board of  Directors or a committee  thereof.  None of
these  plans  have  been  or are  required  to be  approved  by BOK  Financial's
shareholders.

     Options  awarded  under these  plans are  subject to vesting  requirements.
Generally,  one-seventh  of the options  awarded vest  annually and expire three
years after  vesting.  During 2001, BOK Financial  initiated an additional  plan
which awards options that vest in two years.  These options expire 45 days after
vesting.

     The following table presents options outstanding during 2000, 2001 and 2002

Statement.

     The fair value of these  options was estimated at the date of grant using a
Black-Scholes   option   pricing  model  with  the  following   weighted-average
assumptions:
                                  2002      2001      2000
                                --------- --------- ---------
  Average risk-free interest     1.59%     6.04%     5.99%
  rate
  Dividend yield                  None      None      None
  Volatility factors             .190      .195      .194
  Weighted-average
  expected life                 2 years   7 years   7 years

     The  weighted-average  fair value of options  granted during 2002, 2001 and
2000 was $4.18, $8.65 and $5.98, respectively.

     The  Black-Scholes   option  valuation  model  was  developed  for  use  in
estimating  the fair value of traded  options that have no vesting  restrictions
and are fully  transferable.  In addition,  option  valuation models require the
input of highly  subjective  assumptions  including  the  expected  stock  price
volatility.  Because BOK Financial's employee stock options have characteristics
significantly different from those of traded options, and because changes in the
subjective input assumptions can materially  affect the fair value estimate,  in
management's  opinion, the existing models do not necessarily provide a reliable
single measure of the fair value of its employee stock options.

     For  purposes of pro forma  disclosures,  the  estimated  fair value of the
options is  amortized to expense over the  options'  vesting  period.  Pro forma
disclosures are in Note 1 -Significant Accounting Policies.

     During January 2003, BOK Financial awarded 569,105 options to buy shares at
an exercise price of $32.75.  One-seventh  of the options  awarded vest annually
and expire three years after vesting.  The  weighted-average  fair value of this
grant was $8.37. This award was determined by the Chairman of the Board and CEO,
approved by a committee of the Board of Directors and is subject to the approval
of the shareholders.  The approval of the shareholders is considered a formality
since the Board of  Directors  controls  the  majority  of the voting  shares of
common stock.

(14) COMMITMENTS AND CONTINGENT LIABILITIES

     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.

     BOk is obligated under a long-term  lease for its bank premises  located in
downtown Tulsa. The lease term, which began November 1, 1976, is for fifty-seven
years  with  options to  terminate  in 2013 and 2023.  Annual  base rent is $3.3
million.  BOk subleases  portions of its space for annual rents of $406 thousand
in 2003, $388 thousand in 2004, $384 thousand in 2005 and $213 thousand in years
2006 and 2007.  Net rent expense on this lease was $2.9 million in both 2002 and
2001 and $3.1 million in 2000.  Total rent expense for BOK  Financial  was $12.4
million in 2002, $11.8 million in 2001 and $10.5 million in 2000.

     At December 31, 2002,  the future  minimum lease payments for equipment and
premises under operating  leases were as follows:  $11.5 million in 2003,  $11.0
million in 2004,  $10.3 million in 2005,  $9.7 million in 2006,  $8.0 million in
2007 and a total of $103.4 million thereafter.

     BOk and Williams  Companies,  Inc.  severally  guaranteed 30 percent and 70
percent,  respectively, of the $13 million debt, which matures May 15, 2007, and
operating  deficit  of two  parking  facilities  operated  by the Tulsa  Parking
Authority.  Total  expenditures  related to this guarantee were $373 thousand in
2002, $441 thousand in 2001 and $319 thousand in 2000.

     The Federal Reserve Bank requires member banks to maintain  certain minimum
average cash balances.  These balances were  approximately $283 million for 2002
and $262 million for 2001.

(15) 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.

     Commitments  to extend credit are  agreements to lend to a customer as long
as  there  is no  violation  of  any  condition  established  in  the  contract.
Commitments  generally have fixed expiration dates or other termination  clauses
and may require payment of a fee. At December 31, 2002, outstanding  commitments
totaled  $2.9  billion.  Since some of the  commitments  are  expected to expire
before  being  drawn  upon,  the total  commitment  amounts  do not  necessarily
represent future cash requirements.  BOK Financial uses the same credit policies
in making commitments as it does loans.

     The  amount  of  collateral  obtained,  if  deemed  necessary,  is based on
management's  credit  evaluation of the borrower.  Standby letters of credit are
conditional  commitments  issued to guarantee the performance of a customer to a
third party. Since the credit risk involved in issuing standby letters of credit
is  essentially  the same as that involved in extending  loan  commitments,  BOK
Financial uses the same credit  policies in evaluating the  creditworthiness  of
the customer.  Additionally,  BOK Financial uses the same evaluation  process in
obtaining  collateral  on  standby  letters  of  credit  as  it  does  for  loan
commitments.  The term of these  standby  letters  of credit is  defined in each
commitment and typically  corresponds  with the underlying loan  commitment.  At
December 31, 2002, outstanding standby letters of credit totaled $360 million.

     Commercial  letters  of  credit  are  used  to  facilitate  customer  trade
transactions  with the drafts  being drawn when the  underlying  transaction  is
consummated.  At December 31,  2002,  outstanding  commercial  letters of credit
totaled $4 million.

(16) SHAREHOLDERS' EQUITY

PREFERRED STOCK

     One billion  shares of  preferred  stock with a par value of  $0.00005  per
share are authorized. A single series of 250,000,000 shares designated as Series
A  Preferred  Stock  ("Series  A  Preferred  Stock")  is  currently  issued  and
outstanding.  The  Series A  Preferred  Stock  has no  voting  rights  except as
otherwise provided by Oklahoma corporate law and may be converted into one share
of Common Stock for each 38 shares of Series A Preferred  Stock at the option of
the holder.  Dividends  are  cumulative  at an annual rate of ten percent of the
$0.06 per share  liquidation  preference  value when declared and are payable in
cash.  Aggregate  liquidation  preference is $15 million.  During 2002, 2001 and
2000,  47,961  shares,  72,141 shares and 88,628  shares,  respectively,  of BOK
Financial  common  stock were  issued in payment  of  dividends  on the Series A
Preferred  Stock in lieu of cash by mutual  agreement of BOK  Financial  and the
holders  of the Series A  Preferred  Stock.  These  shares  were  valued at $1.5
million in 2002, 2001, 2000, based on average market price, as defined, for a 65
business day period preceding declaration.  Kaiser owns substantially all Series
A Preferred Stock.

     Various   officers  own  125  nonvoting   units  in  an  entity  owned  and
consolidated  by  BOk.  These  units  are  eligible  for an  annual,  cumulative
distribution of $8 per unit and have a preferred value upon  liquidation of $100
per unit.

52

COMMON STOCK

     Common stock consists of 2.5 billion  authorized shares with a $0.00006 par
value.  Holders  of  common  shares  are  entitled  to one vote per share at the
election  of  the  Board  of  Directors  and  on  any  question  arising  at any
shareholders'  meeting and to receive dividends when and as declared.  No common
stock  dividends  can be paid  unless  all  accrued  dividends  on the  Series A
Preferred Stock have been paid. The present policy of BOK Financial is to retain
earnings for capital and future  growth,  and management has no current plans to
recommend payment of cash dividends on common stock.  Additionally,  regulations
restrict  the  ability  of  national  banks and bank  holding  companies  to pay
dividends,  and BOK  Financial's  credit  agreement  restricts  the  payment  of
dividends by the holding company.

     During  2002 and 2001,  3%  dividends  payable  in shares of BOK  Financial
common  stock were  declared  and paid.  The shares  issued  were  valued at $52
million and $35  million,  respectively,  based on the average  closing  bid/ask
prices on the day preceding declaration.  No common stock dividends were paid in
2000.  Per share  data has been  restated  to  reflect  these  stock  dividends.
Presently, management plans to recommend continued payment of an annual dividend
in shares of common stock.

     On October 25, 2002, BOK Financial  issued 1,711,127 shares of common stock
and 292,225 options to purchase  shares,  with a fair value at the issuance date
of $65  million  for its  purchase  of  Bank of  Tanglewood.  In  addition,  BOK
Financial  agreed to a limited price guarantee on a portion of the shares issued
in this  purchase.  The fair value of this price  guarantee,  estimated to be $3
million based upon the  Black-Sholes  Option pricing model,  was included in the
purchase price of Bank of Tanglewood  (see Note 2).  Pursuant to this guarantee,
any  holder  of BOK  Financial  common  shares  issued in this  acquisition  may
annually  make a claim for the  excess of the  guaranteed  price and the  actual
sales price of any shares sold  during a 60-day  period  after each of the first
five  anniversary  dates after  October 25, 2002.  The maximum  annual number of
shares  subject to this  guarantee  is 198,010.  The  guaranteed  price for each
anniversary  period is $34.81 for 2003, $37.38 for 2004, $39.96 for 2005, $42.54
for 2006 and  $45.12  for  2007.  The price  guarantee  is  nontransferable  and
noncumulative.  BOK  Financial  may  elect,  in its  sole  discretion,  to issue
additional  shares of common  stock to satisfy  any  obligation  under the price
guarantee or to pay cash. The maximum aggregate number of common shares that may
be issued to satisfy any price  guarantee  obligations is 10 million.  If, as of
any benchmark  date,  BOK Financial has already  issued 10 million  shares,  BOK
Financial  is  not  obligated  to  make  any  further  benchmark  payments.  BOK
Financial's  ability to pay cash to satisfy any price  guarantee  obligations is
limited by  applicable  bank  holding  company  and bank  capital  and  dividend
regulations.

SUBSIDIARY BANKS

     The amounts of dividends that BOK Financial's  subsidiary banks can declare
and the  amounts  of loans the  subsidiary  banks can extend to  affiliates  are
limited by various federal and state banking regulations.  Generally,  dividends
declared during a calendar year are limited to net profits, as defined,  for the
year plus retained profits for the preceding two years. The amounts of dividends
are further  restricted by minimum  capital  requirements.  Pursuant to the most
restrictive of the regulations at December 31, 2002, BOK Financial's  subsidiary
banks could  declare  dividends  up to $177  million  without  prior  regulatory
approval.  The  subsidiary  banks  declared and paid dividends of $40 million in
2002, $92 million in 2001 and $8 million in 2000.

     Loans  to a  single  affiliate  may  not  exceed  10.0%  and  loans  to all
affiliates may not exceed 20.0% of unimpaired  capital and surplus,  as defined.
Additionally, loans to affiliates must be fully secured. As of December 31, 2002
and 2001, these loans totaled $10 million and $16 million, respectively. None of
the  affiliate  loans  in  2002  were  to  consolidated  entities.   Total  loan
commitments to affiliates at December 31, 2002 were $95 million.

REGULATORY CAPITAL

     BOK Financial and its banking  subsidiaries  are subject to various capital
requirements  administered  by the  federal  banking  agencies.  Failure to meet
minimum capital  requirements  can initiate  certain  mandatory,  and additional
discretionary  actions by  regulators  that could have a material  effect on BOK
Financial's operations. These capital requirements include quantitative measures
of  assets,  liabilities  and  certain  off-balance  sheet  items.  The  capital
standards  are also subject to  qualitative  judgments by the  regulators  about
components, risk weightings and other factors.

     For a banking institution to qualify as well capitalized, its Tier I, Total
and Leverage capital ratios must be at least 6%, 10% and 5%, respectively.  Tier
I  capital  consists  primarily  of  common  stockholders'   equity,   excluding
unrealized gains or losses on available for sale securities, less goodwill, core
deposit premiums and certain other intangible assets. As directed by the Federal
Reserve Bank, Tier I capital excludes $35 million,  the combined value of common
shares issued  subject to the market value  protection  program and the value of
the market value  guarantee.  These values will be restored to Tier I capital as
the market price guarantee  expires.  Total capital consists primarily of Tier I
capital plus preferred  stock,  subordinated  debt and reserves for loan losses,
subject to certain  limitations.  All of BOK  Financial's  banking  subsidiaries
exceeded the regulatory definition of well capitalized.

(18) REPORTABLE SEGMENTS

     BOK Financial  operates four principal  lines of business under its Bank of
Oklahoma franchise:  corporate banking,  consumer banking,  mortgage banking and
trust services.  It also operates a fifth  principal line of business,  regional
banks,  which includes all banking  functions for Bank of  Albuquerque,  Bank of
Arkansas  and Bank of Texas.  These five  principal  lines of business  combined
account for approximately 80% of total revenue.  Other lines of business include
the TransFund  ATM network and BOSC,  Inc. In addition to its lines of business,
BOK Financial has a funds  management  unit. The primary purpose of this unit is
to manage the overall  liquidity  needs and  interest  rate risk of the company.
Each  line of  business  borrows  funds  from and  provides  funds to the  funds
management  unit as needed to support their  operations.  The Corporate  Banking
segment  consists  of eight  operating  units  that  provide  credit  and  lease
financing,  deposit and cash management and international collection services to
commercial  and  industrial  customers and to other  financial  institutions  in
Oklahoma and surrounding  states.  The Consumer  Banking segment consists of two
operating  units that  provide  direct and indirect  consumer  loans and deposit
services to individuals primarily within Oklahoma.  The Mortgage Banking segment
consists  of two  operating  sectors  that  originate  a full range of  mortgage
products  from  federally  sponsored  programs to "jumbo loans" on higher priced
homes in BOK Financial's primary market areas. The Mortgage Banking segment also
services  mortgage loans acquired from  throughout the United States.  The Trust
Services segment consists of one operating unit that provides financial services
to both individual and corporate clients.  Individual financial services include
personal  trust   management,   administration  of  estates  and  management  of
investment and custodial  accounts.  Individual  financial services also include
lending and  investment  services  to select  individuals.  Corporate  financial
services include  administration of employee benefit plans,  transfer and paying
agent services and investment advisory services.  Regional Banks include Bank of
Arkansas, Bank of Albuquerque and Bank of Texas.

     BOK Financial  identifies  reportable  segments by type of service provided
for the Mortgage Banking and the Trust Services segments and by type of customer
for the Corporate  Banking and Consumer  Banking  segments.  Regional  Banks are
identified by legal entity. Operating results are adjusted for intercompany loan
participations and allocated service costs and management fees.

     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 the expected  duration of the accounts.  The expected  duration
ranges from 90 days for  certain  rate-sensitive  deposits  to five  years.  The
accounting  policies of the reportable segments generally follow those described
in the  summary  of  significant  account  policies  except  interest  income is
reported on a fully  tax-equivalent  basis,  loan losses are based on actual net
amounts  charged off and the  amortization  of  intangible  assets is  generally
excluded.  Economic  capital  is  assigned  to the  business  units  based on an
internal  allocation  method  that  reflects  management's  assessment  of risk.
Additional  capital is assigned to the regional  banks line of business based on
BOK Financial's  investment in those entities.  The aggregate  economic  capital
assigned to the lines of business  exceeds the capital required by BOK Financial
in total. Total capital required by BOK Financial reflects management's estimate
of capital required based on the interaction of risk mitigation  strategies that
cross lines of business including regulatory  requirements.  Capital assigned to
the  lines of  business  does  not  reflect  the  company-wide  risk  mitigation
strategies.

     Nonreportable  business  segments include  TransFund ATM networks and BOSC,
Inc.  The sources of revenue in these  segments  include  interest,  commissions
earned  on  securities   transactions,   securities  trading  gains  or  losses,
underwriting  and  financial  advisory  fees and fees earned on various  banking
activities, including merchant discounts and interchange fees.

     Substantially  all revenue is from domestic  customers.  No single external
customer accounts for more than 10% of total revenue.

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


     The  preceding  table  presents  the  estimated  fair  values of  financial
instruments.  The fair values of certain of these instruments were calculated by
discounting  expected  cash  flows,  which  involved  significant  judgments  by
management.  Fair value is the  estimated  amount at which  financial  assets or
liabilities could be exchanged in a current transaction between willing parties,
other than in a forced or liquidation sale. Because no market exists for certain
of these financial  instruments  and because  management does not intend to sell
these financial instruments, BOK Financial does not know whether the fair values
shown above represent values at which the respective financial instruments could
be sold individually or in the aggregate.

59

     The following  methods and  assumptions  were used in  estimating  the fair
value of these financial instruments:

CASH AND CASH EQUIVALENTS

     The book value  reported  in the  consolidated  balance  sheet for cash and
short-term instruments approximates those assets' fair values.

SECURITIES

     The fair values of  securities  are based on quoted market prices or dealer
quotes,  when available.  If quotes are not available,  fair values are based on
quoted prices of comparable instruments.

DERIVATIVES

     Fair value on interest rate  contracts is calculated by a third party based
on  discounted  cash flows  using a yield curve and  current  applicable  market
rates.  Fair value of energy  contracts  are based on closing  prices on the New
York Mercantile Exchange and values provided by energy dealers.

LOANS

     The fair  value of  loans,  excluding  loans  held for  sale,  are based on
discounted  cash flow analyses using interest rates  currently being offered for
loans with similar remaining terms to maturity and credit risk, adjusted for the
impact of interest rate floors and ceilings. The fair values of classified loans
were  estimated to  approximate  their  carrying  values less loan loss reserves
allocated to these loans of $29 million at December 31, 2002 and 2001.

     The fair values of residential  mortgage loans held for sale are based upon
quoted  market  prices  of  such  loans  sold  in  securitization  transactions,
including related unfunded loan commitments and hedging transactions.

DEPOSITS

     The fair values of time deposits are based on discounted cash flow analyses
using interest rates currently being offered on similar transactions.  Statement
of  Financial  Accounting  Standard  No. 107,  "Disclosures  about Fair Value of
Financial Instruments," ("FAS 107") defines the estimated fair value of deposits
with no stated maturity,  which includes demand deposits,  transaction deposits,
money  market  deposits  and savings  accounts,  to equal the amount  payable on
demand.  Although market premiums paid reflect an additional value for these low
cost deposits,  FAS 107 prohibits  adjusting fair value for the expected benefit
of these  deposits.  Accordingly,  the positive  effect of such  deposits is not
included in this table.

OTHER BORROWINGS AND SUBORDINATED DEBENTURE

     The fair values of these  instruments  are based upon  discounted cash flow
analyses using interest rates currently being offered on similar instruments.

OFF-BALANCE-SHEET INSTRUMENTS

     The fair values of commercial  loan  commitments  and letters of credit are
based on fees currently  charged to enter into similar  agreements,  taking into
account  the  remaining  terms  of the  agreements.  The  fair  values  of these
off-balance-sheet  instruments  were not  significant  at December  31, 2002 and
2001.
