ITEM 1 - BUSINESS

                          GENERAL DEVELOPMENT OF BUSINESS

BOK Financial  Corporation ("BOK Financial") was incorporated  under the laws of
the State of Oklahoma on October 24, 1990.  Active  operations as a bank holding
company  commenced on June 7, 1991 with the  acquisition of the preferred  stock
("BOk Preferred Stock") of Bank of Oklahoma,  National  Association ("BOk") from
the Federal Deposit Insurance Corporation ("FDIC") and the conversion of the BOk
Preferred  Stock  into  99.99% of the  common  stock of BOk.  BOK  Financial  is
regulated by the Board of Governors of the Federal  Reserve  System  pursuant to
the Bank Holding Company Act of 1956, as amended ("BHCA").

BOK Financial  operates  primarily through BOk, BOk's  subsidiaries and Citizens
Bank of Northwest Arkansas,  National  Association  ("CBNWA").  The existing and
future activities of BOK Financial and its subsidiaries are limited by the BHCA,
which  prohibits a bank holding company from engaging in any business other than
banking,  managing or controlling  banks, and furnishing and performing  certain
bank-related services and activities.

Shares  disclosed  in the  following  transactions  have not been  restated  for
subsequent stock dividends.

On June 7,  1991,  BOK  Financial  paid  $60.75  million to the FDIC for the BOk
Preferred  Stock. To finance this  acquisition,  BOK Financial  issued preferred
stock  totaling  $15.0  million  at $6.00 per share and  common  stock  ("Common
Stock")  totaling  $46.0  million  at  $5.75  per  share  to  George  B.  Kaiser
("Kaiser"),   BOK  Financial's  principal   shareholder.   Kaiser  purchased  an
additional  $10.0 million of BOK Financial  Common Stock at $5.75 per share, and
BOK Financial  contributed the $10.0 million to BOk as additional  capital.  Per
share amounts  reflect a 1-for-100  reverse stock split  effective  December 17,
1991 ("reverse stock split").

Following  a bidding  process  conducted  by the  Resolution  Trust  Corporation
("RTC"),  BOK  Financial,  through  the  mortgage  banking  subsidiary  of  BOk,
BancOklahoma  Mortgage Corp.  ("BOMC"),  acquired on June 10, 1991 approximately
$1.0  billion of mortgage  servicing  rights and certain  other  assets of Maxim
Mortgage  Corporation  ("Maxim").  Maxim was  formerly  a  subsidiary  of Sooner
Federal Savings and Loan Association, which had failed and had been placed under
the control of the RTC.

Also following a bidding process by the RTC, BOK Financial acquired on August 9,
1991 certain assets and assumed  certain  liabilities,  primarily  deposits,  of
eight branches of Continental  Federal Savings and Loan  Association of Oklahoma
City,  Oklahoma.  BOK Financial assumed deposits of approximately $214.5 million
and paid the RTC a premium of $4.1 million.  Kaiser acquired an additional $20.0
million of BOK Financial's  Common Stock at $5.75 per share (after effect of the
reverse stock split), and BOK Financial  contributed the $20.0 million to BOk to
facilitate the purchase.

On March 27, 1992,  CBNWA  acquired  certain assets and assumed the deposits and
certain  obligations  of two branches of the failed Home Federal  Savings & Loan
Association from the RTC for $1.1 million.

On July 16, 1992,  Bank of Oklahoma,  N.A.,  South,  an  unconsolidated  banking
subsidiary, was merged into BOk.

On November 13, 1992, BOK Financial purchased Southwest Trustcorp,  Inc. and its
subsidiary,  The Trust  Company of  Oklahoma,  Oklahoma  City,  in exchange  for
400,000 shares of Common Stock valued at $4.6 million.

On December 31, 1992, BOK Financial  acquired  certain assets and assumed $502.9
million of deposits and other  liabilities of 19 branches of the Sooner Division
of First  Gibraltar  Bank,  FSB of Irving,  Texas for a purchase  price of $16.5
million.

On May 7, 1993,  BOK  Financial  issued  343,295  common  shares  valued at $6.9
million and paid $3.9 million to acquire Sand Springs  Bancshares,  Inc. and its
subsidiary, Sand Springs State Bank.

Also on May 7, 1993,  BOK Financial  issued  1,183,691  common shares to acquire
Brookside  Bancshares,  Inc.  and its  subsidiary,  Brookside  State Bank,  in a
pooling-of-interests  transaction.  Financial  information  of BOK Financial for
1992 and 1991 has been restated to reflect this acquisition.

On October 9, 1993,  BOK  Financial  acquired  certain  assets and  assumed  the
deposits and certain obligations of two branches of the failed Heartland Federal
Savings & Loan Association from the FDIC for $5.1 million.

On May 2, 1994,  BOK  Financial  acquired  Plaza  National  Bank,  Bartlesville,
Oklahoma for $11.7 million.

On June 13, 1994, BOK Financial acquired Texas Commerce Trust Company - Sherman,
National  Association,  Sherman,  Texas, a national association limited to trust
powers only, for $6.1 million.

<PAGE> 3 

On  October  7, 1994,  BOK  Financial  acquired  Northwest  Bank of Enid,  Enid,
Oklahoma for $8.2 million.

On November 14, 1994, BOK Financial  issued  1,380,017  common shares to acquire
Citizens  Holding  Company and its  subsidiaries,  Citizens Bank of Muskogee and
Citizens  Bank  of  Northwest  Arkansas,  in a  pooling-of-interests.  Financial
information of BOK Financial for 1993 and 1992 has been restated to reflect this
acquisition.

On February 12, 1997, BOK Financial  acquired Park Cities  Bancshares,  Inc. and
its subsidiary,  First National Bank of Park Cities, in Dallas,  Texas for $50.0
million.

On  March  4,  1997,  BOK  Financial  acquired  First  TexCorp.,  Inc.  and  its
subsidiary, First Texas Bank, in Dallas, Texas for $39.3 million.

Developments relating to individual aspects of the business of BOK Financial are
described under  "Narrative  Description of Business" and "Services  Offered" on
pages  3  and  4 of  this  report.  Additional  discussion  of  BOK  Financial's
activities during the current year is incorporated by reference to "Management's
Assessment  of  Operations  and  Financial  Condition"  (pages  6 - 18)  in  BOK
Financial's 1996 Annual Report to Shareholders. Additional information regarding
BOK Financial's acquisitions is incorporated by reference to Note 2 of "Notes to
Consolidated  Financial  Statements"  (page 28 ) in BOK Financial's  1996 Annual
Report to Shareholders.

                        NARRATIVE DESCRIPTION OF BUSINESS

BOK Financial is a bank holding company, and as such, its activities are limited
by the BHCA to  banking,  certain  bank-related  services  and  activities,  and
managing  or  controlling  banks.  BOK  Financial's   banking  and  bank-related
activities are primarily  performed  through BOk and CBNWA;  nonbank  subsidiary
operations are not  significant.  As of December 31, 1996, BOK Financial and its
subsidiaries  had  2,102  full-time   equivalent   employees.   Following  is  a
description of the more  significant  services  offered by BOK Financial and the
competitive and regulatory environments in which it operates.

                                 SERVICES OFFERED

COMMERCIAL BANKING SERVICES

BOK  Financial,  through  BOk and  CBNWA,  provides  a wide  range of  financial
services to commercial and industrial customers,  including depository,  lending
and other financial services such as cash management,  leasing and international
collections.  The loan  portfolio  is  comprised  primarily  of real  estate and
commercial  loans.  The commercial loan portfolio is diversified and distributed
among various  commercial and industrial  customers,  including  energy-related,
manufacturing, trade and service industries.

CORRESPONDENT BANKING SERVICES

BOK Financial provides a broad range of financial services to banks, savings and
loans,   credit  unions  and  other  financial   institutions  in  Oklahoma  and
surrounding  states.  BOK  Financial  works  closely  with  community  financial
institutions,  assisting them in satisfying  the demands of their  customers and
trade areas by engaging in loan  participations  and providing  other  financial
services.

CONSUMER BANKING SERVICES

At December 31,  1996,  BOk had 65 banking  locations,  with 45 locations in the
Tulsa and Oklahoma  City areas.  CBNWA had 4 locations  in  northwest  Arkansas.
Services offered include deposit  accounts,  installment  loans,  student loans,
bank card accounts,  personal lines of credit, debit cards, an automated 24-hour
telephone loan application service, a 24-hour telephone branch and telephone and
personal  computer  based bill paying  services  New  services  planned for 1997
include  interactive  video kiosks for consumer lending and other  transactions.
The BancOklahoma  Investment Center makes available,  through representatives in
most BOk  branches,  a full range of mutual  funds,  annuities  and  securities.
TransFund, BOk's network of automated teller machines, consists of 635 locations
across  Oklahoma,  Arkansas,  southwest  Missouri,  northern  Texas and southern
Kansas.

INVESTMENT AND MONEY MARKET ACTIVITIES

BOk  provides  securities  brokerage,  and trading  services  for  corporations,
governmental units,  individual  customers and correspondent  banks.  Securities
include money market instruments, U.S. Government and municipal bonds, corporate
stocks and bonds,  and mutual  funds.  The public  finance  department  provides
bank-elegible   underwriting   financial   advisory,   private   placement   and
term-financing  services for governmental and corporate entities.  BOK Financial
recently announced its entrance into merchant banking which will provide a broad

including financial advisory

<PAGE> 4

services to both public and corporate sectors,  leasing and mezzanine financing,
and  underwriting of municipal  revenue bonds,  mortgage  backed debt,  consumer
receivables, and commercial paper.

MORTGAGE BANKING

BOMC, through its own locations as well as BOk's branch network,  offered a full
array of mortgage options from federally  sponsored programs to "jumbo loans" on
higher  priced  houses.  BOMC is the largest  originator  of  mortgage  loans in
Oklahoma and has a servicing portfolio of approximately $5.9 billion,  including
$243 million serviced for BOk. Effective January 1, 1997, these mortgage banking
activities were transferred to BOk.

TRUST AND ASSET MANAGEMENT SERVICES

BOk's trust  subsidiaries  (BancOklahoma  Trust Company ("BOTC") in Oklahoma and
Alliance  Trust  Company  N.A.  in Texas)  offer a variety of  services  to both
corporate and individual  customers in Oklahoma and Texas.  Individual financial
trust services include personal trust management,  administration of estates and
management  of  individual  investment  and  custodial  accounts.  For corporate
clients,  the services include  management,  administration and recordkeeping of
pension plans,  thrift plans,  401(k) plans and master trust plans,  including a
state-of-the-art  system for employee  benefit plan  recordkeeping.  BOk's trust
division also serves as transfer  agent and registrar for corporate  securities,
paying agent for municipalities and governmental  agencies and indenture trustee
of bond issues. BOTC serves as an investment advisor to the American Performance
Funds, a family of proprietary  mutual funds distributed by the Winsbury Company
of Columbus, Ohio. At December 31, 1996, trust subsidiaries were responsible for
approximately $7.5 billion in assets.  Effective March 22, 1997, BOTC was merged
into BOk.

                               FOREIGN OPERATIONS

BOK Financial  does not engage in operations in foreign  countries,  nor does it
lend to foreign governments.

                                  COMPETITION

The banking industry in Oklahoma is highly  competitive.  BOK Financial competes
with other banks in obtaining  deposits,  making loans and providing  additional
services  related  to  banking.  There are  approximately  332 banks  located in
Oklahoma,  of  which  approximately  38 are  located  in the  Tulsa  County  and
surrounding  metropolitan  area and approximately 55 are located in the Oklahoma
County and surrounding  metropolitan  area. BOK Financial is also in competition
with other businesses engaged in extending credit or accepting deposits, such as
major  retail   establishments,   major  brokerage   firms,   savings  and  loan
associations,  credit unions, finance companies, small loan companies, insurance
companies and loan production  offices of major banks located within and outside
Oklahoma.

Limited  branch  banking as  permitted  in Oklahoma is  increasing  competition.
Generally,  a bank may establish two new branch  offices within the town or city
where the bank is located  or in nearby  areas not  already  served by a bank or
branch,  and may acquire an unlimited  number of existing banks and convert them
and their branches into branch offices.  Within its primary markets,  BOk has 23
locations  in the Tulsa area and 22 locations  in the  Oklahoma  City area,  the
state's  largest  financial  markets.  Subject to  regulatory  approval,  BOk is
considering various locations for additional  facilities.  Like BOk, other banks
are  taking  advantage  of the  bank  branching  laws  to  establish  additional
facilities. These additional banking offices are further increasing competition.
Limited branch banking is, on the other hand,  permitting  banks to compete more
effectively  with  savings  and  loan  associations,  credit  unions  and  other
financial  institutions  that may establish offices more freely than banks, some
of  which  are not  subject  to  comparable  regulatory  restrictions  on  their
activities.

Oklahoma also permits the  acquisition  of an unlimited  number of  wholly-owned
bank subsidiaries so long as aggregate  deposits at the time of acquisition in a
multibank  holding  company do not exceed  12.25% of all  deposits  in  Oklahoma
financial  institutions  insured by the federal government,  exclusive of credit
union deposits.  Based on the latest  statistical data available (as of June 30,
1996), BOK Financial could acquire  additional bank  subsidiaries so long as the
aggregate deposits of all Oklahoma subsidiaries do not exceed approximately $4.1
billion.  Deposits  of BOk were $3.1  billion  and $3.2  billion at June 30, and
December 31, 1996, respectively.

Oklahoma also permits  out-of-state  bank holding companies to acquire banks and
bank holding companies located in the state and, subject to certain limitations,
make  additional  acquisitions  within the state.  During the last few years the
Oklahoma banking industry has been  consolidated into fewer but larger banks. In
1996, two "super-regional"  holding companies announced significant acquisitions
in Oklahoma.  The consolidation  over the past several years has brought about a
highly competitive environment,  in which many customers have access to national
and regional financial institutions for many products and services.

<PAGE> 5

On  September  29,  1994,  the  Riegle-Neal  Interstate  Banking  and  Branching
Efficiency  Act of  1994  ("Riegle-Neal")  was  signed  into  law.  In  summary,
commencing one year after  passage,  qualifying  bank holding  companies will be
permitted to acquire banks in any state.  As of June 1, 1997,  qualifying  banks
may be able to engage in  interstate  branching  by merging  banks in  different
states.   States  "  opt-out"  of  interstate  branching  by  enacting  specific
legislation  prior to June 1,  1997,  in which  case  out-of-state  banks  would
generally not be able to branch into that state, and banks headquartered in that
state would not be  permitted to branch into other  states.  States may also opt
into interstate branching earlier than 1997 with specific  legislation.  The law
imposes a 10% nationwide  deposit cap and a 30% state deposit cap; however,  the
states' authority is preserved to impose a lower, nondiscriminatory deposit cap.
Oklahoma  elected to "opt-in" to  interstate  branching  effective  May 1997 and
established  a 12.25%  deposit cap. It is  anticipated  that the total number of
Oklahoma banks may decrease and national and regional bank presence in the state
may  increase.  Over the  near-term,  these  changes  are  expected  to increase
competition with a greater number of products and services available to Oklahoma
customers.  Over the  long-term,  the  number  of  competitors  could  decrease,
depending on the extent of  consolidations  nationwide,  but  competition  could
continue  to increase as a result of the  remaining  institutions  needing to be
stronger,  more innovative and more aggressive to retain a significant  presence
in a consolidated environment.

Additional  legislation,  judicial and administrative  decisions also may affect
the  ability  of  banks  to  compete  with  each  other  as well  as with  other
businesses.  These  statutes and  decisions  may tend to make the  operations of
various financial institutions more similar and increase competition among banks
and other  financial  institutions or limit the ability of banks to compete with
other businesses.  Management  currently cannot predict whether and, if so, when
any such changes  might occur or the impact any such changes would have upon the
income or operations of BOK Financial or its subsidiaries,  or upon the Oklahoma
regional banking environment.

                             SUPERVISION AND REGULATION

Bank holding  companies and banks are  extensively  regulated under both federal
and state law. The following  information,  to the extent it describes statutory
or  regulatory  provisions,  is  qualified  in its  entirety by reference to the
particular  statutory and regulatory  provisions.  It is not possible to predict
the changes,  if any, that may be made to existing  banking laws and regulations
or whether such changes,  if made, would have a materially adverse effect on the
business and prospects of BOK Financial, BOk and CBNWA.

BOK FINANCIAL

As a bank holding company, BOK Financial is subject to regulation under the BHCA
and to supervision by the Board of Governors of the Federal  Reserve System (the
"Reserve  Board").  Under the BHCA,  BOK  Financial is required to file with the
Reserve  Board an annual  report and such other  additional  information  as the
Reserve Board may require.  The Reserve Board may also make  examinations of BOK
Financial and its subsidiaries.

The BHCA  requires the prior  approval of the Reserve  Board in any case where a
bank holding  company  proposes to acquire  control of more than five percent of
the voting  shares of any bank,  unless it already  controls a majority  of such
voting  shares.  Additionally,  approval  must  also be  obtained  before a bank
holding  company may acquire all or  substantially  all of the assets of another
bank or before it may merge or  consolidate  with another bank holding  company.
The BHCA  further  provides  that the  Reserve  Board shall not approve any such
acquisition, merger or consolidation that will substantially lessen competition,
tend to create a  monopoly  or be in  restraint  of  trade,  unless it finds the
anti-competitive  effects of the proposed  transaction are clearly outweighed in
the public  interest by the probable  effect of the  transaction  in meeting the
convenience and needs of the community to be served.

The BHCA  presently  prohibits the Reserve Board from  approving an  application
from a bank  holding  company to acquire  shares of a bank  located  outside the
state in which the operations of the holding company's banking  subsidiaries are
principally conducted,  unless such an acquisition is specifically authorized by
statute  of the state in which  the bank  whose  shares  are to be  acquired  is
located, but Riegle-Neal permits interstate banking as of September 29, 1995, as
discussed above in "Competition".

The BHCA also prohibits a bank holding company,  with certain  exceptions,  from
acquiring more than five percent of the voting shares of any company that is not
a bank and from  engaging  in any  business  other than  banking or  managing or
controlling  banks.  Under the BHCA,  the Reserve Board is authorized to approve
the  ownership  of  shares  by a  bank  holding  company  in any  company  whose
activities the Reserve Board has determined to be so closely  related to banking
or to managing  or  controlling  banks as to be a proper  incident  thereto.  In
making such determinations,  the Reserve Board weighs the Community Reinvestment
Act  activities  of the bank  holding  company and the  expected  benefit to the
public,  such  as  greater  convenience,   increased  competition  or  gains  in
efficiency, against the possible adverse effects, such as undue concentration of
resources,  decreased  or unfair  competition,  conflicts of interest or unsound
banking practices.  The Reserve Board has by regulation  determined that certain
activities are closely related to banking within the meaning of the BHCA.  These
activities  include operating a mortgage company,  finance company,  credit card
company

or factoring company;  performing certain data processing operations;  servicing
loans and other extensions of credit; providing investment and financial advice;
acting as an  insurance  agent for certain  types of  credit-related  insurance;
owning  and  operating  savings  and loan  associations;  and  leasing  personal
property on a full-payout, nonoperating basis.

A bank holding and its subsidiaries  are further  prohibited under the BHCA from
engaging in certain tie-in  arrangements in connection with the provision of any
credit,  property or services.  Thus, a subsidiary of a bank holding company may
not extend credit,  lease or sell property,  furnish any services or fix or vary
the  consideration  for these  activities on the condition that (1) the customer
obtain or provide some  additional  credit,  property or services from or to the
bank  holding  company or any  subsidiary  thereof or (2) the  customer  may not
obtain some other credit, property or services from a competitor,  except to the
extent  reasonable  conditions  are  imposed to insure the  soundness  of credit
extended.

The Federal Deposit  Insurance  Corporation  Improvement Act of 1991 established
five  capital  rating  tiers  ranging  from "well  capitalized"  to  "critically
undercapitalized".  A financial institution is considered to be well capitalized
if its  Leverage,  Tier 1 and  Total  Capital  ratios  are  at 5%,  6% and  10%,
respectively. Any institution experiencing significant growth or acquiring other
institutions  or branches is expected to maintain  capital ratios above the well
capitalized  level. At December 31, 1996, BOK Financial's  Leverage,  Tier 1 and
Total Capital ratios were 7.46%, 10.49% and 11.74%, respectively.

BOK AND CBNWA

BOk and CBNWA are national banking  associations and are subject to the National
Banking Act and other federal statutes  governing  national banks. Under federal
law, the Office of the  Comptroller  of the Currency  ("Comptroller")  charters,
regulates and serves as the primary  regulator of national  banks.  In addition,
the Comptroller must approve certain corporate or structural changes,  including
an increase or decrease in capitalization, payment of dividends, change of place
of  business,  establishment  of a  branch  and  establishment  of an  operating
subsidiary.  The  Comptroller  performs  its  functions  through  national  bank
examiners who provide the Comptroller with information  concerning the soundness
of a national bank, the quality of management and directors, and compliance with
applicable laws, rules and regulations.  The National Banking Act authorizes the
Comptroller to examine every  national bank as often as necessary.  Although the
Comptroller has primary  supervisory  responsibility  for national  banks,  such
banks must also comply with Reserve  Board rules and  regulations  as members of
the Federal Reserve System.

CBNWA is also subject to certain  consumer-protection  laws  incorporated in the
Arkansas  Constitution,  which,  among  other  restrictions,  limit the  maximum
interest  rate on  general  loans to five  percent  above  the  Federal  Reserve
Discount  Rate.  The rate on consumer  loans is five percent  above the discount
rate or seventeen percent, whichever is lower.

BOk and CBNWA are insured by the FDIC and are  required to pay certain  fees and
premiums  to the  Bank  Insurance  Fund  ("BIF").  The  BIF  has  implemented  a
risk-related  insurance  system for  determining  premiums to be paid by a bank.
Each bank is placed in one of nine risk categories based on its level of capital
and  supervisory  rating  with  the  well-capitalized  banks  with  the  highest
supervisory  rating  paying a premium of 0.00% of  deposits  and the  critically
undercapitalized banks paying up to 0.27% of deposits.  Also,  approximately 21%
of BOK  Financial's  total  deposits at December 31, 1996 were acquired  through
Oakar  transactions  and are insured through the Savings  Association  Insurance
Fund ("SAIF").  The Deposit Insurance Funds Act of 1996 was enacted on September
30, 1996, which recapitalized the SAIF and implemented a risk-related  insurance
system  identical to the BIF system  discussed  above. In addition,  the Deposit
Insurance Fund Act of 1996 implemented an additional  assessment on BIF and SAIF
deposits,  the Financing  Corporation  ("FICO") Quarterly Payment,  which is not
tied to the BIF risk  classification.  The FICO BIF annual  rate is 1.296  basis
points and the FICO SAIF annual rate is 6.48 basis points.

Applicable  federal  statutes and  regulations  require  national  banks to meet
certain  leverage and  risk-based  capital  requirements.  At December 31, 1996,
BOk's and CBNWA's  leverage and  risk-based  capital  ratios were well above the
required minimum ratios.

                     GOVERNMENTAL POLICIES AND ECONOMIC FACTORS

The operations of BOK Financial and its subsidiaries are affected by legislative
changes  and  by  the  policies  of  various  regulatory   authorities  and,  in
particular,  the credit policies of the Reserve Board. An important  function of
the Reserve Board is to regulate the national  supply of bank credit.  Among the
instruments  of  monetary  policy  used by the Reserve  Board to  implement  its
objectives are: open market operations in U.S. Government securities; changes in
the discount rate on bank  borrowings;  and changes in reserve  requirements  on
bank  deposits.  The effect of such  policies in the future on the  business and
earnings  of BOK  Financial  and  its  subsidiaries  cannot  be  predicted  with
certainty.

The Oklahoma economy, BOK Financial's primary market,  continues to generate job
growth. Certain economic indicators show that employment growth within the state
has now exceeded U.S. employment growth for fifteen consecutive months, although
wage and salary  growth in  Oklahoma  only  slightly  exceeded  the growth  rate
observed nationally. With Oklahoma's economy tied more closely with the national
economy  than in the past,  a downturn  in the  national  economy  could have an
adverse impact on BOK Financial's financial position and results of operations.

ITEM 2 - PROPERTIES

BOK Financial,  through BOk, BOk's  subsidiaries  and CBNWA,  owns improved real
estate that was carried at $31.0 million,  net of depreciation and amortization,
as of December 31, 1996. BOK Financial  conducts its operations  through a total
of 65 banking and 4 nonbanking  locations in  Oklahoma,  4 banking  locations in
Arkansas  and 2 nonbanking  locations  in Texas as of December  31, 1996.  BOk's
facilities are suitable for their respective uses and present needs.

COMMON STOCK
     On November 14, 1994, BOK Financial issued 1,380,017 shares of Common Stock
to merge with Citizens  Holding Company and its  subsidiaries,  Citizens Bank of
Muskogee  and  Citizens  Bank of  Northwest  Arkansas in a  pooling-of-interests
transaction.  Common  shares have been restated to reflect these shares as being
outstanding for all periods presented.  During 1996, 1995 and 1994, 3% dividends
payable in shares of BOK Financial  common stock were declared and paid.  Common
shares have been restated to reflect these shares as being  outstanding  for all
periods.

STOCK OPTIONS
     BOK Financial  has various  stock option plans whereby each option  awarded
grants to the employee the right to purchase shares of Common Stock at the price
set forth  under the  respective  plan.  Options  awarded  under these plans are
subject to vesting  requirements.  Generally,  one-seventh  of the options  vest
annually and expire three years after  vesting.  Options were awarded  under the
1994 Plan in 1994,  1995, and 1996.  Canceled options under the 1994 Plan may be
reawarded.  The  common  share  equivalents  of  the  Stock  Option  Plans  were
determined  using the  treasury  stock  method,  whereby the  proceeds  from the
exercise of the options would be used to purchase  Common Stock at the quarterly
average market price for primary  average common share  equivalents,  and at the
greater of the quarterly  average  market price or  period-end  market price for
primary average common share equivalents.

SERIES A PREFERRED STOCK
     The preferred stock is convertible,  at the option of the holder,  into one
share Common Stock for each 89 shares of Series A Preferred Stock. BOK Financial
may elect to convert  all or part of the Series A  Preferred  Stock into  Common
Stock if BOK  Financial  shall  fail to meet the  published  minimum  risk-based
capital  ratios  applicable to BOK  Financial for a period of eight  consecutive
calendar quarters. During 1996, 1995 and 1994, 69,672 shares, 69,959 shares, and
65,279  shares of Common Stock were issued,  respectively,  by mutual  agreement
with the holders and in lieu of cash,  in payment of  dividends  on the Series A
Preferred  Stock.  Common  shares have been  restated to reflect these shares as
being  outstanding for all periods.  For the 1996, 1995 and 1994 calculations of
primary  earnings  per share,  net  income has been  reduced by the value of the
Common Stock issued in payment of dividends.
     Prior to its  merger  with BOK  Financial,  Citizens  Holding  Company  had
nonvoting  preferred  stock, on which it paid $113 thousand in cash dividends in
1994.  These preferred  shares were redeemed in full and canceled in conjunction
with Citizens' merger with BOK Financial.  For the 1994  calculations of primary
and fully diluted earnings per share, net income has been reduced by the payment
of cash dividends.

TO OUR SHAREHOLDERS, CUSTOMERS, EMPLOYEES AND FRIENDS      

   Last year  continued  the  pattern of change and  consolidation  in the
financial  services industry which has characterized the past several years. Our
company  recorded a very successful year in this  environment,  both financially
and strategically,  and we are pleased to report on this performance and discuss
our goals for the future.

         Net  income  for the year was $54.1  million,  or $2.24 per  share,  an
increase of 10 percent  over 1995  earnings,  or 9 percent on a per share basis.
Recurring  core  earnings  grew at a materially  faster  pace.  The increase was
derived  from an improved net  interest  margin and very strong  growth in other
operating  revenue.  Loans grew by 11.9 percent,  with a total  increase of $240
million,  and deposits  increased in excess of $440  million,  the result of our
emphasis on improving our funding sources  following  several years during which
loan  growth had  outstripped  core  funding  growth.  Our net  interest  margin
increased 15 basis points,  to 3.54 percent,  principally  due to a reduction in
low margin reinvested borrowings.

(Net Income graph appears here.  See Appendix A, graph I)

         Growth in other  operating  revenues  was  dramatic  -- with an overall
increase of 20 percent -- and with every line of business  making a  significant
contribution to the increase.  Mortgage banking,  brokerage operations,  and our
TransFund electronic funds transfer network each contributed increases in excess
of 25 percent.  Operating  expenses  grew 6.5 percent,  excluding  non-recurring
charges  totaling  $7.6 million  resulting  from Federal  legislative  action to
recapitalize  the Savings  Association  Insurance Fund and a related decision we
made to eliminate core deposit intangible assets associated with acquired thrift
deposits.

IS THERE A NEW COMPETITIVE LANDSCAPE?

         Oklahoma's  banking  industry saw dramatic shifts during 1996. Our last
two  multi-billion  dollar  competitors  announced  sales to large  out-of-state
banks, leaving BOk as the only locally owned and managed institution of its size
in the state.  BOK Financial now has an historic  

<PAGE> 2


opportunity to differentiate  itself as Oklahoma's leading bank, and as the only
major  statewide  financial  institution  with a  single  minded  commitment  to
building the Oklahoma  economy and  employment  base. We are confident that BOk,
with its roots and future tied to  Oklahoma's,  will thrive in an environment in
which  our   national   franchise   competitors   are  hobbled  by   multi-level
decisionmaking and lack of sensitivity to the needs of local customers.

ABOUT 1996

         Commercial  banking  activity  continued  at  a  strong  pace.  Average
commercial loans increased over 13 percent for the year, ending at a new high of
$1.66  billion.  Growth  in cash  management  income  was  particularly  strong,
increasing  14  percent.  During the year,  we were  successful  in winning  the
business  of  several  major  companies  against  national  competition,   again
attesting to the quality of our entire package of corporate services.

(Loans graph appears here.  See appendix A, graph II).  

         Our supermarket  banking expansion  continued,  with five new locations
opened in 1996, and with plans to add eight more  supermarket  branches in 1997.
This expansion will bring us to 23 supermarket  locations and a total network of
75 in Oklahoma,  Arkansas and Texas -- the clear  leader in  convenience  in our
markets. During 1996, we also introduced personal computer banking and announced
plans to  introduce  interactive  video  kiosks for  consumer  lending and other
transactions.  Customer  convenience  was  further  augmented  by BOk's  24-hour
ExpressBank,  our  telephone  sales and service  center which was  introduced in
1995. By offering the ultimate in convenience, the ExpressBank grew dramatically
last  year,  handling  more than 1 million  calls  and  generating  more than 25
percent of our consumer loan applications.

(Real Estate Loans graph appears here.  See appendix A, graph III).

         BOk Mortgage, the state's leading mortgage originator,  grew 32 percent
in total production -- including a 46 percent growth in retail production -- and
now has a servicing portfolio of $5.9 billion.  Wholesale and retail residential
originations  have totaled $2.9 billion since 1992.  

<PAGE> 3

New  production  offices  in  Fayetteville,  Bentonville,  and  Siloam  Springs,
Arkansas,  were opened.  BOk Mortgage also acquired the leading mortgage company
serving  Lawton,  Oklahoma,  and $628  million in servicing  rights  distributed
across the nation.

         TransFund,  the state's largest  electronic  funds transfer network and
ranked among the 25 largest networks nationally,  continued its excellent growth
pattern, with operating revenue up 31 percent.  Total transaction volume grew by
27  percent,  led by the  tremendous  marketing  success  of its Visa Check Card
service,  which had an increase in transaction volume of 133 percent.  TransFund
serves more than 175 financial  institutions in Oklahoma with a growing presence
in surrounding states.

         BancOklahoma Trust, the state's leading fiduciary organization, in 1996
began marketing a specially designed 401(k) product directed at certain targeted
types of firms with large  individual  accounts.  This product has met with very
encouraging  success  in  its  initial  stages,   including  sales  in  national
competition  to  major  out-  of-state  law  firms.  The  Trust  Company  is now
responsible  for $7.5  billion in assets,  placing it among the top 75 corporate
fiduciaries nationwide.

         For the  past  several  years,  one of our  fastest  growing  and  most
successful  businesses  has been the sale of  investment  services.  Last  year,
revenue  from this area  increased  31  percent.  In  addition,  BOk ranked 38th
nationally  among all banks in long-term  mutual fund sales.  We have also filed
for  approval to open  Alliance  Securities  Corp.,  which will  concentrate  on
providing  investment  banking  services  to  municipalities  and/or  tax-exempt
entities.

(Operating Revenue graph appears here.  See appendix A, graph IV).

      Operationally,  Alliance  Securities will be an integral part of our newly
announced  merchant banking unit, which will be responsible for a broad range of
financial  services outside those  traditionally  associated with banking.  This
will include financial advisory and underwriting services in both the public and
corporate sectors, leasing and mezzanine financing.

         In late  1996,  BOK  Financial  announced  the  signing  of  definitive
agreements  to acquire the $226 million  First  National Bank of Park Cities and
the $142 million First Texas Bank, both located in Dallas.  Both agreements were
consummated in the first quarter of 1997. Park Cities has  distinguished  itself
as the premier bank in north Dallas, catering to high income business owners and
professionals.  First  Texas'  greatest  strength  is  its  expertise  in  small
businesses  lending.  Both  organizations  are  financially  sound and extremely
well-managed.  Through  this  combination  of  skills  plus  Bank of  Oklahoma's
strength in middle-market commercial lending and our pre-existing Alliance Trust
Company, we now are in position to build a strong, competitive banking franchise
in the north Texas market.

(Funding Graph appears here.  See appendix A, graph V).

      Our board of directors, which includes the current or immediate past chief
executive  officers  of four of the  state's  five  Fortune  500  companies  and
prominent entrepreneurs and community leaders from across the state, was further
strengthened  during 1996 by the additions of Mr. David R. Lopez,  President for
the  Oklahoma  region of  Southwestern  Bell  Telephone  Co.,  and Mr.  James W.
Pielsticker,  President and owner of Arrow Trucking. Both additions evidence our
commitment  to having the  strongest  board of directors  of any  publicly  held
company in our state,  and are the essential  element to the continuation of the
leadership  role we see for BOK  Financial  Corporation.  We also  accepted  the
resignations  of two  long-time  directors,  Thomas J. Hughes III and William B.
Cleary,  who retired from our board during 1996.  We will  sincerely  miss their
seasoned  insight which has contributed so  significantly to the progress of our
company.

      As always, we appreciate your support and your business.



      Sincerely,

Management's Assessment of Operations and Financial Condition

     BOK Financial Corporation ("BOK Financial") is a bank holding company which
offers  full  service  banking in  Oklahoma  and  Northwest  Arkansas  and trust
services in North Texas.  BOK  Financial's  principal  subsidiaries  are Bank of
Oklahoma,  NA ("BOk"),  Citizens Bank of Northwest Arkansas,  NA ("CBNWA"),  and
Alliance Trust Company,  NA ("Alliance").  CBNWA will change its name to Bank of
Arkansas  on May 1,  1997.  During the fourth  quarter  of 1996,  BOK  Financial
announced the signing of definitive agreements to acquire the $226 million First
National  Bank of Park Cities  ("Park  Cities") and the $142 million First Texas
Bank ("First Texas"),  both located in Dallas,  Texas.  These  acquisitions will
further  the  development  of a niche  strategy  of serving  small-business  and
middle-market  customers in  complement  to the trust  operation of Alliance and
BOk's existing portfolio of energy loans in Dallas.


ASSESSMENT OF OPERATIONS

SUMMARY OF PERFORMANCE

     BOK  Financial  recorded net income of $54.1  million for 1996  compared to
$49.2 million for 1995.  Fully diluted  earnings per common share were $2.24 for
1996 and $2.05 for 1995. Returns on average assets and average equity were 1.26%
and 16.80%,  respectively,  for 1996 compared to 1.22% and 18.07%, respectively,
for 1995.

     The increase in net income for 1996 was due to  increases of $12.2  million
or 10.6% in net interest  revenue and $14.2 million or 15.5% in other  operating
revenue.  These increases were partially  offset by a $16.8 million  increase in
operating expense,  which included $7.6 million of nonrecurring  charges related
to deposits insured by the Savings and Loan Insurance Fund ("SAIF"),  and a $4.0
million increase in provision for loan losses.

     Net  income for the  fourth  quarter of 1996 was $14.6  million or $.60 per
fully diluted  common share,  an increase of 15.0%  compared to $12.7 million or
$.53 per fully  diluted  common  share for the same period in 1995.  The primary
sources of increased  quarterly earnings included net interest revenue and other
operating revenue, which increased $2.8 million and $3.6 million,  respectively,
partially  offset by a $1.5 million  increase in  operating  expenses and a $2.8
million increase in income taxes.

     BOK  Financial's  net income for 1994 was $45.1  million or $1.88 per fully
diluted  common share.  Returns on average  assets and average equity were 1.26%
and 19.92%, respectively.


NET INTEREST REVENUE

     Net interest revenue, on a tax-equivalent  basis, totaled $135.8 million in
1996 compared to $122.3 million in 1995.  This increase in net interest  revenue
was due to increases in both net interest margin and average earning assets. The
yield on average  earning assets  decreased from 7.84% to 7.79% due primarily to
an 18 basis point  decrease in the yield on the loan  portfolio.  However,  this
decrease was partially  offset by an improvement  in the mix of earning  assets.
Approximately  57.6% of average  earning  assets  for 1996 were in loans,  which
generally  have a higher yield than other types of earning  assets,  compared to
54.8% in 1995.  Additionally,  average earning assets  increased by $231 million
while average  interest  bearing  liabilities  increased  $163 million.  The $68
million  difference,  which was funded by  increases  in both capital and demand
deposits, also contributed to the increase in net interest revenue.

     Additionally,  BOK Financial  continued  efforts to restructure its funding
sources during 1996. Average  interest-bearing  deposits increased $398 million,
including  increased  transaction  deposits of $90 million and time  deposits of
$325 million. Concurrently,  average borrowed funds decreased $235 million. This
shift in the mix of interest-bearing  liabilities,  combined with slightly lower
interest  rates,  resulted  in  a  decrease  in  the  cost  of  interest-bearing
liabilities  from 5.11% in 1995 to 4.94% in 1996.  In  addition,  interest  rate
swaps, which hedge against interest rate risk on certain long-term  certificates
of deposit,  reduced  interest  expense by $1.4 million in 1996 compared to $868
thousand in 1995. The effects of the changes in principal  balances and interest
rates on net interest revenue by asset and liability type are presented in Table
2.

     Net interest  margin,  the ratio of net interest  income to average earning
assets,  increased  from 3.39% in 1995 to 3.54% in 1996.  This  increase was due
primarily to the previously discussed  improvement in the mix of average earning
assets and  interest-bearing  liabilities  along with the  increased  funding of
average earning assets with non-interest-bearing funds. Since inception in 1990,
BOK Financial has followed a strategy of fully  utilizing its capital  resources
by  borrowing  funds in the capital  markets to  supplement  deposit  growth and
invest  in  securities.  Although  this  strategy  frequently  results  in a net
interest margin which falls below those normally seen in the commercial  banking
industry,  it provides positive net interest revenue. As more fully discussed in
the  subsequent  Interest Rate  Sensitivity  and Liquidity  section,  management
employs  various  techniques  to control,  within  established  parameters,  the
interest rate and liquidity risk inherent in this strategy.

     During 1996, two super regional banks announced significant acquisitions in
Oklahoma.  The financial  services  environment  in Oklahoma was already  highly
competitive due to a large number of commercial  banks,  thrifts,  credit unions
and brokerage  firms in the market.  Additionally,  many customers  already have
access to national and regional  financial  institutions  for many  products and
services.  Management  does not expect the  replacement  of  existing  financial
institutions by these banks to significantly alter the competitive environment.
 
     Tax  equivalent  net  interest  revenue for the fourth  quarter of 1996 was
$34.5  million  compared to $31.2  million for the fourth  quarter of 1995.  The
increase is due primarily to an overall decrease in the cost of interest-bearing
liabilities. Rates paid on interest-bearing deposits decreased by 9 basis points
to 4.71% for the fourth quarter of 1996.  Additionally,  the average  balance of
borrowed  funds  decreased $86 million as funding needs were met by increases in
both interest-bearing deposits and noninterest-bearing funds.
         
     Net interest  revenue on a tax  equivalent  basis for 1995  decreased  $2.8
million to $122.3  million  compared  to 1994's  total of $125.1  million.  This
decrease was due to rising market  interest rates which affected BOK Financial's
interest-bearing  liabilities  more quickly than its earning  assets.  While the
yield on average  earning assets  increased by 63 basis points to 7.84% compared
to 7.21% in 1994, the cost of interest-bearing  liabilities  increased 131 basis
points to 5.11%.

OTHER OPERATING REVENUE

     Other operating revenue, which consists primarily of fee income on products
and services, increased $14.2 million or 15.5% compared to 1995. Excluding gains
and  losses on  securities  sales and branch  facilities  in both  years,  other
operating  income  increased  $19.4  million or 21.9%.  Service fees on deposits
totaled  $24.1  million,  an increase of $3.0 million or 14.0%  compared to 1995
while revenue  generated by the  TransFund  ATM network and bankcards  increased
$1.8 million and $1.1 million,  respectively.  These increases are generally due
to a higher volume of activity in 1996.
   
     Other revenue  increased $3.2 million or 20% compared to 1995, $4.7 million
or 31.8%  excluding gains and losses on branch sales in both 1996 and 1995. This
increase is due  primarily to increased  revenue from  equipment  leasing  which
totaled $2.2  million in 1996.  The  financing of specialty  oil field and other
energy-related  equipment through operating leasing was developed during 1996 as
a complement to BOK Financial's expertise in energy lending.

     Many of BOK  Financial's fee generating  activities,  such as brokerage and
trading activities,  trust fees and mortgage servicing revenue,  are affected by
changes in interest rates.  Significant  increases in interest rates may tend to
decrease  the  volume of  trading  activities,  and may lower the value of trust
assets  managed,  which is the basis of certain fees, but would tend to decrease
the incidence of mortgage loan  prepayments.  Similarly,  a decrease in economic
activity would decrease ATM, bankcard and other related revenue.

     While management expects continued growth in other operating  revenue,  the
rate of  increase  achieved  for 1996 may not be  sustainable  due to  increased
competition from national and regional financial institutions which have entered
the Oklahoma market and from market saturation. Continued growth may require BOK
Financial to introduce  new  products or to enter new markets  which  introduces
additional demands on capital and managerial resources.

    Other  operating  revenue  for the  fourth  quarter of 1996  totaled  $27.5
million  compared  to  $24.0  million  for  the  fourth  quarter  of  1995.  All
significant revenue producing activities contributed to this increase, including
$1.3 million from mortgage  banking,  $809 thousand from deposit fees,  and $735
thousand from equipment leasing.

     Other  operating  revenue  increased  $12.5  million  or  16.4%,  excluding
securities  gains and losses and a $1.2  million gain on the sale of one branch,
in 1995 compared to 1994.  This increase was primarily due to growth in mortgage
banking revenue which increased $4.5 million,  trust fees and commissions  which
increased $2.2 million,  and TransFund revenue and bankcard fees which increased
$986 thousand and $708 thousand, respectively.

     Other  operating  revenue  includes  fees,   commissions  and  certain  net
marketing  gains and losses from trust and mortgage  banking  activities.  While
trust and mortgage banking  activities are integral parts of a commercial bank's
operation,  their revenue and expenses are attributable primarily to off-balance
sheet  assets.  The  effects of trust and  mortgage  banking  activities  on BOK
Financial's operations are discussed in the following sections.



TRUST

     BOK Financial provides a wide range of trust services through  BancOklahoma
Trust Company in Oklahoma and Alliance Trust Company,  NA in Texas.  At December
31,  1996,  trust assets with an aggregate  market value of  approximately  $7.5
billion were subject to various fiduciary arrangements, compared to $7.6 billion
at December 31, 1995.

MORTGAGE BANKING

     BOK  Financial  has  engaged  in  mortgage   banking   activities   through
BancOklahoma   Mortgage  Corp.  ("BOMC").   Effective  January  1,  1997,  these
activities will be transferred to BOk. These activities include the origination,
marketing and  servicing of mortgage  loans.  Notes 1 and 7 to the  Consolidated
Financial Statements provide additional  information  regarding mortgage banking
activities.

     Origination and marketing activities resulted in a net gain of $48 thousand
in 1996 compared to a net loss of $1.5 million in 1995.  The  improvement is due
primarily to a full year's effect of Statement of Financial Accounting Standards
No.  122,  "Accounting  for  Mortgage  Servicing  Rights"  ("FAS 122") which was
adopted April 1, 1995 and an increase in the volume of mortgage loans originated
by BOMC.  FAS 122 required  that the fair value of servicing  rights  related to
loans  originated for sale in the secondary  market be capitalized as a separate
asset.   Previously,   only  purchased   mortgage   servicing  rights  could  be
capitalized.  Total mortgage loan  production for 1996 increased $173 million to
$706  million  compared to $533  million in 1995.  This  included a $125 million
increase in retail loan  production.  

     Commitments  to  originate  mortgage  loans  subject BOK  Financial to both
credit risk and interest rate risk. Credit risk is managed through  underwriting
policies and  procedures,  and interest  rate risk is partially  hedged  through
forward sales  contracts.  BOMC generally sells all fixed rate mortgage loans in
the secondary market pursuant to forward sales contracts and all adjustable rate
loans to an affiliate.  BOMC  currently  does not  securitize  pools of mortgage
loans either for sale or retention.
        
     Consolidated  mortgage loan servicing revenue for 1996 was $26.2 million, a
$4.3 million or 19.7% increase over 1995. The increase reflects continued growth
in the mortgage  servicing  portfolio which increased to $5.9 billion at the end
of 1996  from $5.4  billion  at the end of 1995.  These  amounts  include  loans
serviced  for  BOk  of  $243  million  and  $253  million  for  1996  and  1995,
respectively.

     Capitalized  mortgage  servicing  rights,  which  totaled  $61.5 million at
December 31, 1996 and $50.6 million at December 31, 1995, represent the value of
mortgage  loans  serviced for others  carried at the lower of amortized  cost or
fair value.  Fair value is based on the present value of projected net servicing
revenue over the estimated life of the mortgage loans  serviced.  This estimated
life and the value of the  servicing  rights is very  sensitive  to  changes  in
interest rates and loan  prepayment  assumptions.  Rising interest rates tend to
decrease  loan  prepayments  and increase the value of mortgage  loan  servicing
rights while falling  interest  rates have the opposite  effect.  Management has
estimated  that a 200 basis point decrease in interest rates would cause a $17.8
million  decrease in the carrying value of the  capitalized  mortgage  servicing
rights that would be recognized through a charge to pre-tax income under current
accounting principles.
    
     Statement  of  Financial  Accounting  Standards  No.  125,  Accounting  for
Transfers and Servicing of Financial  Assets and  Extinguishment  of Liabilities
("FAS 125") was issued  during 1996 and  becomes  effective  on January 1, 1997.
Among other things,  FAS 125 extends the requirement that a valuation  allowance
be provided for the difference  between the amortized  historical  cost and fair
value  of all  capitalized  servicing  rights  stratified  by  predominant  risk
characteristics   to  all  capitalized   servicing  rights.   Previously,   such
stratification  was required only for  servicing  rights  capitalized  after the
adoption of FAS 122.  The result of this change will be to further  increase the
volatility of reported  earnings as the fair value of servicing  rights react to
changes in interest rates and prepayment assumptions.

OTHER OPERATING EXPENSE

     Other operating  expense totaled $159.0 million for 1996 compared to $142.2
million in 1995. Excluding  non-recurring  charges of $7.6 million to record the
write off of intangible  assets  related to deposits  insured by the Savings and
Loan  Insurance  Fund  ("SAIF") and a special  deposit  insurance  assessment to
recapitalize SAIF, operating expenses for 1996 increased 6.5% compared to 1995.
    
     The transition toward  performance based compensation and variable staffing
continued  during 1996.  Personnel costs increased $4.6 million or 6.9% compared
to 1995.  This  included an increase in incentive  compensation  expense of $1.7
million or 37.3%  compared to 1995 due to growth in revenue over  pre-determined
targets.  Additionally,  part-time and temporary  compensation expense increased
$435  thousand or 11.3%.  Employee  benefits  remained  constant as increases in
payroll  taxes and cost of the pension and thrift plans were offset by decreases
in the cost of health insurance.

     Net  occupancy,  equipment and data  processing  expense for 1996 increased
$3.5 million or 12.8% compared to 1995. Data processing  expense  increased $2.2
million due to a higher volume of transactions  processed. A significant portion
of BOK  Financial's  data  processing  is  performed  by service  bureaus  under
agreements  which provide for charges per  transaction.  Therefore,  these costs
will vary in direct relation to the number of transactions.

     Additionally,  equipment expense increased $750 thousand,  primarily due to
depreciation   expense.   During  1994  through  1996,  BOK  Financial  invested
approximately  $12.0  million to upgrade its computer and  telecommuni-  

<PAGE> 10

cations networks, item processing equipment,  lockbox equipment,  and other
improvements  in technology.  An additional $5 million is planned to be invested
in 1997. These investments,  which allow BOK Financial to compete effectively by
providing products and services which are valued by our customers, will increase
depreciation expense over the next three to five years.

     Mortgage  banking costs  increased $3.3 million or 26.4% due primarily to a
$1.9 million  increase in the  amortization  of capitalized  mortgage  servicing
rights.  This  increase  is  consistent  with  the  growth  in  the  balance  of
capitalized servicing rights. Additionally,  expenses related to the origination
and servicing of government  guaranteed  loans  increased  $1.6 million due to a
larger volume of transactions.

     Since 1991, BOK Financial  acquired  deposits  insured by the SAIF totaling
approximately $843 million. In conjunction with these acquisitions, core deposit
intangible assets which represent the future earnings  potential of these funds,
were recorded. In determining the value of these core deposit intangible assets,
assumptions  were made  regarding  the returns  which were expected to be earned
over the costs which would be incurred,  including interest expense,  processing
costs and deposit  insurance  premiums.  During 1995,  the FDIC made a change in
deposit insurance premiums which  significantly  decreased the value of deposits
insured by SAIF. The premium  assessed on deposits insured by the Bank Insurance
Fund ("BIF") was reduced to 3 basis points (.03%) while the premium  assessed on
SAIF insured deposits remained at 23 basis points (.23%). Legislation to resolve
this  difference had been expected from Congress at December 31, 1995.  However,
at the end of the first  quarter  of 1996,  the  expected  legislation  had been
removed from the agenda and the  resolution  of the  differential  between rates
assessed  on  SAIF  insured  deposits  compared  to  BIF  insured  deposits  was
uncertain.  This uncertainty,  in addition to heightened  competitive  pressures
caused the spreads  between  the actual  returns  and costs to  decrease.  These
conditions  caused  the  value of these  core  deposit  intangible  assets to be
impaired and a write down of $3.8 million was recognized.

     During the third quarter of 1996,  legislation to resolve the  differential
between rates paid on SAIF insured  deposits and BIF insured  deposits was again
placed on the  Congressional  agenda.  On September  30, 1996,  legislation  was
enacted  which was designed to  recapitalize  SAIF and to equalize  SAIF and BIF
premium rates. This legislation  included a one-time assessment against all SAIF
insured deposits,  including  approximately  $740 million held by BOK Financial.
The  amount of this  special  deposit  insurance  assessment  was $3.8  million.
Following this assessment,  management expects future deposit insurance premiums
to decrease by approximately $1.2 million each year.

     During the third quarter of 1996, BOK Financial sold two nonaccruing  loans
for cash,  notes and other  consideration.  This sale  resulted in a recovery of
amounts  previously charged off of approximately $2.7 million which was recorded
as an addition to the allowance for loan losses,  a gain of  approximately  $2.0
million  which was  included in net gains and losses on the sale of  repossessed
assets,  and a reduction  in  nonaccruing  commercial  real estate loans of $3.7
million.

     Other  operating  expenses  for the fourth  quarter of 1996  totaled  $38.3
million  compared to $36.9 million for the fourth quarter of 1995.  Increases in
mortgage  banking and data processing  costs were partially offset by a decrease
in  deposit  insurance  premiums  and an  increase  in net  gains on the sale of
repossessed assets. Additionally, amortization of intangible assets decreased as
a  result  of the  previously  discussed  write  off  of  certain  core  deposit
intangible assets.

     The efficiency ratio, the ratio of other operating expenses,  excluding net
gains on real estate  sales and  SAIF-related  charges,  to  tax-equivalent  net
interest  revenue and other operating  revenue,  excluding  securities gains and
losses,  decreased  to 64.0%  during  1996  compared  to  68.5%  in  1995.  This
improvement is due to growth in both net interest revenue and operating  revenue
along with limitations on the growth of operating expenses.

     Operating  expenses for 1995  increased  $12.5  million or 9.4% compared to
1994,  excluding gains on the sale of repossessed assets and a $5.2 million loss
on certain purchased  mortgage loans in 1994. The increases are primarily due to
higher  personnel  costs  caused by  additional  staffing in support of expanded
products and services,  higher data processing  costs due to increased volume of
transactions, and higher mortgage banking costs, also due to increased volume of
loans originated and serviced.

INCOME TAXES

     Income tax expense was $15.3 million,  $14.8 million, and $14.6 million for
1996, 1995, and 1994, respectively, representing 22%, 23%, and 25%, respectively
of book taxable income.  Tax expense  currently payable totaled $19.0 million in
1996  compared  to  $17.0  million  in 1995  and  $13.7  million  in  1994.  The
acquisition  of BOk by BOK  Financial in 1991  resulted in a change in ownership
which, under tax regulations,  significantly  limited the utilization of certain
tax benefits  during a five year period from the  acquisition  date.  Because of
these  limitations  and  uncertainties  regarding  the  timing of when these tax
benefits  would be  available  and BOK  Financial's  ability to generate  future
taxable  income,  a  valuation  allowance  had  been  recorded.  This  valuation
allowance was  periodically  evaluated and adjusted  based upon  assessments  of
these  limitations  and  uncertainties.  In the second quarter of 1996, the five
year limitation period expired.  Accordingly,  the remaining valuation allowance
has been eliminated. Income tax expense for 1997 is expected to be approximately
31% of pre-tax  book  income,  consistent  with  amounts  recorded  during 1996,
excluding  the valuation  allowance  reversal.  See Note 10 to the  Consolidated
Financial  Statements  for a  detailed  discussion.  BOk and BOK  Financial  are
currently  under  audit by the  Internal  Revenue  Service  for  1992 and  1993,
respectively.  The ultimate  outcome of this audit cannot be determined with any
certainty at this time.  However,  management expects no material adverse impact
on the financial statements.

ASSESSMENT OF FINANCIAL CONDITION

SECURITIES PORTFOLIO

     Securities are identified as either  investment or available for sale based
upon various factors, including asset/liability management strategies, liquidity
and profitability objectives, and regulatory requirements. Investment securities
are carried at cost,  adjusted  for  amortization  of premiums or  accretion  of
discounts.   Amortization   or  accretion  of   mortgage-backed   securities  is
periodically adjusted for estimated  prepayments.  Available for sale securities
are  those  which  may be sold  prior to  maturity  based  upon  asset/liability
management decisions. Securities identified as available for sale are carried at
fair value.  Unrealized  gains or losses,  less applicable  deferred taxes,  are
recorded in Shareholders' Equity.

     During 1996,  BOK Financial  increased  its holdings of  marketable  equity
securities  by $72.5  million  based on  historical  cost.  Approximately  $41.5
million of this increase was from purchases of government agency preferred stock
which offers attractive yields with little market value risk. Additionally,  BOK
Financial  increased  the cost  basis of its  holdings  in the  common  stock of
another bank by $12.8 million.  The fair value of this stock has  appreciated by
$6.8 million due to a pending acquisition of the bank.
   
     Table 6  presents  the book  values  and  fair  values  of BOK  Financial's
securities portfolio at December 31, 1996, 1995 and 1994. Additional information
regarding the  securities  portfolio is presented in Note 4 to the  Consolidated
Financial Statements.

LOANS

     During 1996,  loans  increased  $200 million or 9.1%,  continuing an upward
trend in loan  volumes  which  began in 1991.  This  increase  was the result of
continued  strength in the Oklahoma  economy and taking advantage of disruptions
in banking  relationships caused by high-profile bank mergers.  Commercial loans
increased $123 million or 14.3% and commercial  real estate loans  increased $77
million or 12.9%.

     The  composition  of the  loan  portfolio  shifted  toward  commercial  and
commercial real estate loans during 1996.  Commercial loans totaled $984 million
or 41% of the portfolio,  compared to 39% in 1995. This included energy loans of
$217 million or 9.1% of the total loan  portfolio.  Commercial real estate loans
totaled $676 million or 28% at December 31, 1996.

     Substantially  all of the commercial and consumer loans, and  approximately
77% of the  residential  mortgage loans  (excluding  loans held for sale) are to
businesses and  individuals in Oklahoma or Northwest  Arkansas.  This geographic
concentration  subjects the loan  portfolio to the general  economic  conditions
within this area.  Notable  segments  within the  commercial  loan portfolio are
presented  in Table 7.  Commercial  real estate  loans are secured  primarily by
properties located in the Tulsa or Oklahoma City,  Oklahoma  metropolitan areas.
The major  components of these  properties are  multifamily  residences,  $146.2
million;  office  buildings,   $82.3  million;  hotels,  $70.6  million;  retail
facilities, $60.8 million; and medical/nursing facilities, $70.3 million.

     BOK Financial  monitors loan performance on a portfolio and individual loan
basis.  Nonperforming  loans are reviewed at least  quarterly  and are discussed
subsequently under the caption  "Nonperforming  Assets." The loan review process
involves evaluating the credit worthiness of customers and their ability,  based
upon current and anticipated economic  conditions,  to meet future principal and
interest  payments.  Loans may be identified  which possess more than the normal
amount of risk due to deterioration  in the financial  condition of the borrower
or the  value  of the  collateral.  Because  the  borrowers  are  performing  in
accordance  with  the  original  terms  of the  loan  agreements  and no loss of
principal  or  interest  is  anticipated,  such  loans are not  included  in the
Nonperforming Assets totals. These loans are assigned to various risk categories
in order to focus management's  attention on the loans with higher risk of loss.
At  December  31,  1996,  loans  totaling  $40  million  were  assigned  to  the
substandard  risk  category and loans  totaling $62 million were assigned to the
special mention category, compared to $42 million and $40 million, respectively,
at December 31, 1995.

 SUMMARY OF LOAN LOSS EXPERIENCE

     The reserve for loan losses,  which is available to absorb losses  inherent
in the loan portfolio, totaled $45 million at December 31, 1996, compared to $38
million at December 31, 1995.  This  represents  1.96% and 1.80% of total loans,
excluding  loans held for sale,  at December  31,  1996 and 1995,  respectively.
Losses  on  loans  held  for  sale,   principally   residential  mortgage  loans
accumulated for placement in securitized  pools, are charged to earnings through
adjustments in carrying value to the lower of cost or market value in accordance
with  accounting  standards  applicable  to mortgage  banking.  Table 9 presents
statistical  information regarding the reserve for loan losses for the past five
years.

     The adequacy of the reserve for loan losses is assessed by management based
upon an evaluation  of the current risk  characteristics  of the loan  portfolio
including  current  economic  conditions,   historical  experience,   collateral
valuation,  changes  in the  composition  of the  portfolio  and other  relevant
factors.  A  provision  for loan losses is charged  against  earnings in amounts
necessary  to  maintain  the  adequacy of the  reserve  for loan  losses.  These
provisions totaled $4.3 million for 1996 and $0.2 million for 1995 and 1994. The
increased provision for 1996 reflected management's assessment of increased risk
of loss due primarily to continued  growth in the loan portfolio,  moderation of
economic  activity  in  BOK  Financial's   primary  market  areas,  and  drought
conditions  which prevailed over much of Oklahoma during the first half of 1996.
Additionally,  the  allowance  increased  by $2.6 million due to  recoveries  of
amounts previously charged off in excess of current year loan charge offs. It is
expected  that  continued  growth  in the loan  portfolio  will  require  1997's
provision for loan losses to be comparable to 1996.

     Table 10 presents management's  allocation of the year-end reserve for loan
losses for the past five years. The changes in the various  allocations  reflect
the  changing  composition  of the  loan  portfolio  and the  changing  economic
environment in BOK Financial's market area. In addition to reserves allocated to
specific  loans or  categories  of  loans,  reserves  are  maintained  for other
relevant  factors such as national and local economic  conditions and the nature
and volume of the loan portfolio.

NONPERFORMING ASSETS

     Nonperforming  assets  totaled $42  million at December  31, 1996 and 1995.
Although  total  nonperforming  assets  remained  unchanged,  nonaccruing  loans
decreased  $10.5  million  while loans past due 90 days or more  increased  $9.4
million.  The  decrease in  nonaccruing  commercial  real  estate  loans was due
primarily to the  previously  discussed  sale of two  nonaccruing  loans and the
decrease in nonaccruing commercial loans was due primarily to payments received.
 
     Information  regarding  nonperforming  assets  is  presented  in Table  11.
Nonperforming loans include nonaccrual loans, loans 90 days or more past due and
renegotiated loans. Loans 90 days or more past due at December 31, 1996 included
$13.9 million of residential  mortgage loans  guaranteed by agencies of the U.S.
Government.  These  loans were  purchased  from  various  investors  to minimize
operating  costs.  The allowance  for loan losses as a percent of  nonperforming
assets  increased to 120% at December  31, 1996  compared to 99% at December 31,
1995 due to the increase in allowance for loan losses previously discussed.  See
Note 5 to the Consolidated Financial Statements for additional information.

DEPOSITS

     Average deposits for 1996 increased $444 million or 16.6% compared to 1995.
This includes  increases of $46 million in average demand  deposit  accounts and
$398 million in average interest-bearing deposit accounts. As shown in Table 12,
average core deposits  increased  $182 million and were $2.3 billion or 73.2% of
average deposits.  Average estimated  uninsured  deposits increased $172 million
and were $565 million or 18.1% of average deposits.  Average estimated uninsured
deposits included  approximately  $147 million of brokered  deposits.  Uninsured
deposits as used in this  presentation  is based on a simple analysis of account
balances and does not reflect combined ownership and other account stylings that
would determine insurance based on FDIC regulations.  These changes,  along with
the increase in public funds  reflect  steps taken by  management  to reduce BOK
Financial's  reliance on borrowed funds and to increase  deposits as a source of
funding.

     BOK  Financial  competes for deposits by offering a broad range of products
and services to its customers.  While this includes  offering interest rates and
fees which are competitive with other financial institutions,  the primary means
of  competing  for deposits is  convenience  and service to the  customers.  BOk
extended its ability to exceed its  competition  by offering  24-hour  telephone
banking  through  ExpressBank  and by adding 5 branches with  extended  hours in
local  supermarkets.  BOK Financial plans to open 8 new supermarket  branches in
1997 to further enhance customer convenience.

BORROWINGS

     Average  borrowings for 1996  decreased  $229 million  compared to 1995 and
represented  18.5% of total  funding  sources,  down from  25.3%  for 1995.  The
decrease in borrowings was offset by growth in average deposits and capital. See
Note 9 to the Consolidated Financial Statements for additional information.

CAPITAL

    Equity capital of BOK Financial  averaged $322 million and $272 million for
1996 and  1995,  respectively.  The $50  million  increase  resulted  from  1996
earnings and a decrease in unrealized losses on available for sale securities.

     Management has identified capital and funding needs which total $84 million
for current  commitments,  including the  acquisitions  of Park Cities and First
Texas,  and  an  additional  $40  million  in  capital  and  funding  needs  for
anticipated  growth  through  1997.  Resources  available  to meet  the  current
commitments  include  existing lines of credit with commercial banks which total
$50 million and an agreement with its principal shareholder to issue $20 million
Tier 2  qualifying  debt.  The  remainder  of the  commitment  will be funded by
dividends  from BOK  Financial's  bank  subsidiaries.  Management is negotiating
additional  lines of  credit  up to a total  of $80  million  and a $30  million
increase in Tier 2 qualifying  debt.  If all capital and funding  resources  are
successfully obtained and fully drawn, BOK Financial will incur approximately $8
million to $10 million of additional  interest expense per year.  Dividends from
BOK Financial's  subsidiary  banks will be the primary source of repayment.  The
timing and extent of future  growth  plans  will be  reevaluated  based upon the
availability  of  these  resources.  See Note 15 to the  Consolidated  Financial
Statements for additional information.

INTEREST RATE SENSITIVITY AND LIQUIDITY

     BOK  Financial's   asset/liability   management  policy  addresses  several
complementary  goals:  assuring adequate  liquidity,  maintaining an appropriate
balance between interest  sensitive  assets and liabilities,  and maximizing net
interest revenue.  The  responsibility  for attaining these goals rests with the
Asset/Liability Committee which operates under policy guidelines which have been
established  by the Board of  Directors.  These  guidelines  limit the  negative
acceptable variation in net interest revenue and economic value of equity due to
a 200 basis point rate  increase or  decrease  to + / - 10%,  establish  maximum
levels for short-term  borrowings,  short-term  assets,  and public and brokered
deposits, and establish minimum levels for unpledged assets, among other things.
Compliance with these guidelines is reviewed monthly.  At December 31, 1996, BOK
Financial is within all guidelines established under these policies.

     Interest rate  sensitivity,  the risk  associated  with changes in interest
rates,  is of primary  importance  within the banking  industry.  Management has
established  strategies and procedures to protect net interest  revenue  against
significant changes in interest rates. Generally,  these strategies are designed
to achieve an acceptable level of net interest  revenue based upon  management's
projections of future changes in interest rates.  Table 14 presents the interest
rate sensitivity of earning assets and interest bearing  liabilities at December
31,  1996.  This table  indicates  that  changes in interest  rates would affect
interest-bearing  liabilities  much more quickly than earning  assets based upon
their  contractual  repricing.  However,  assets and  liabilities  with  similar
contractual repricing characteristics may not reprice at the same time or to the
same degree.
        
     Most notably,  interest-bearing transaction and savings deposits, which are
shown as repricing in 1 - 30 days, do not reprice according to their contractual
terms.  Historical  trends  indicate that the repricing of these deposits extend
across all repricing periods through five years. As a result,  the interest rate
sensitivity  gap analysis is not the best  indicator of the impact of changes in
interest rates on net interest  revenue.  Additionally,  the maturity of certain
securities  and loans is based on prepayment  assumptions  which change based on
changes in interest rates.

     Management  simulates  the  potential  effect of changes in interest  rates
through computer  modeling which  incorporates both the current gap position and
the  expected  magnitude  of the  repricing  of  specific  types of  assets  and
liabilities.  This modeling is performed  assuming  expected interest rates over
the next twelve  months based on both a "most  likely" rate  scenario and on two
"shock test" rate  scenarios,  the first assuming a 200 basis point increase and
the second  assuming a 200 basis point decrease over the next twelve months.  An
independent  source is used to determine the most likely  interest rates for the
next  year.  At  December  31,  1996,  this  modeling  indicated  interest  rate
sensitivity as follows:

                               200 bp      200 bp     Most
                              increase    decrease    Likely
                              ---------- ----------- ---------
Anticipated impact in next twelve months compared to 1996 actual results:

     Net interest revenue       1.0%        (1.2)%    0.6%
     Net income                 1.4        (11.9)     0.9
     Economic value of equity  (7.7)         2.5     (1.7)

     The estimated  impact of changes in interest rates on net interest  revenue
is not  projected  to be  significant  within the + / - 200 basis point range of
assumptions.  However,  this modeling  indicates  that under the 200 basis point
decrease  scenario the after-tax value of BOK Financial's  capitalized  mortgage
servicing  rights,  net of mortgage loan refinancing  income,  would decrease by
approximately $6.6 million. While this decrease in value would largely offset an
increase in the value of the securities portfolio, current accounting principles
require  that the net  decreased  value of  mortgage  loan  servicing  rights be
charged to earnings while the increased  value of available for sale  securities
be credited to shareholders'  equity. The result is an estimated decrease in net
income of 11.9%.  Additionally,  a 200 basis point  increase  in interest  rates
would  decrease  the  economic  value of  equity  by 7.7% due  primarily  to the
decrease in value of the securities portfolio. This decrease is compared against
the  applicable  policy which  limits the  negative  impact of a 200 basis point
change  in  interest  rates  on the  economic  value  of  equity  to 10%.  These
simulations are based on numerous assumptions regarding the timing and extent of
repricing characteristics. Actual results may differ significantly.

     BOK  Financial  uses  interest  rate  swaps,  a form of  off-balance  sheet
derivative product,  in managing its interest rate sensitivity.  These swaps are
primarily  used to more closely  match the interest  paid on certain  long-term,
fixed  rate  certificates  of  deposit  with  earning  assets.  Swaps  allow BOK
Financial to offer these deposits to its customers  without altering the desired
repricing  characteristics.  BOK Financial  accrues and periodically  receives a
fixed  amount  from  the  counter   parties  to  these  swaps  and  accrues  and
periodically makes a variable payment to the counterparties. During 1996, income
from these swaps exceeded  costs of the swaps by $1.4 million.  Credit risk from
these swaps is closely  monitored  and  counterparties  to these  contracts  are
selected on the basis of their credit worthiness among other factors. Derivative
products are not used for speculative purposes.  See Note 14 to the Consolidated
Financial Statements for additional information.

     The best  measure of  liquidity is the ability to obtain funds to meet cash
requirements.  Liquidity  is  achieved  through  maturities  of earning  assets,
securities  available for sale and loans held for sale.  On the liability  side,
liquidity  depends on the availability of deposits and short-term  borrowings in
both the local and national markets for the subsidiary banks.

     Cash  provided by  operations  in 1996 totaled $56 million,  or $77 million
excluding the effect of changes in mortgage  loans held for sale.  This compares
to cash  provided by  operations  of $23 million,  or $56 million  excluding the
increase in mortgage loans held for sale, in 1995.

     Investing  activities used $318 million,  primarily for net loan funding of
$201  million  and a net  increase  in  securities  of $111  million.  Financing
activities provided $318 million due to growth in transactional deposit accounts
of $211 million and certificates of deposit of $108 million.

       REPORT OF MANAGEMENT ON FINANCIAL STATEMENTS

     Management is responsible for the consolidated  financial  statements which
have been prepared in accordance with generally accepted accounting  principles.
In management's  opinion,  the consolidated  financial statements present fairly
the financial conditions,  results of operations and cash flows of BOK Financial
and  its   subsidiaries   at  the   dates   and  for  the   periods   indicated.

     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  generally  accepted
accounting principles.  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  an 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,  considers and approves certain
of BOK  Financial's  accounting  principles and practices,  and reviews  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  generally  accepted  auditing
standards 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  and  subsidiaries at December 31, 1996 and 1995, 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,
1996.  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  generally  accepted  auditing
standards.  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  consolidated  financial  statements  of BOK Financial
Corporation and subsidiaries  referred to above present fairly,  in all material
respects,  the consolidated  financial position of BOK Financial  Corporation at
December 31, 1996 and 1995, and the consolidated results of their operations and
their cash flows for each of the three years in the period  ended  December  31,
1996, in conformity with generally accepted accounting principles.

     As  described  in Note 1 in 1995,  BOK  Financial  Corporation  changed its
method of accounting for mortgage servicing rights.

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 generally accepted  accounting
principles,   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")
and Citizens Bank of Northwest  Arkansas,  N.A.  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 and North Texas. 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  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.  Intangible assets are amortized using  straight-line and
accelerated methods over the estimated benefit periods. These periods range from
7 to 25 years for goodwill and 7 to 10 years for core deposit  intangibles.  The
net book values of intangible  assets are evaluated for impairment when economic
conditions  indicate an impairment  may exist.  The  Consolidated  Statements of
Earnings  include the results of purchases  from the dates of  acquisition.  The
financial statements of companies acquired in pooling-of-interests  transactions
are combined  with the  Consolidated  Financial  Statements  of BOK Financial at
historical  cost as if the mergers  occurred at the  beginning  of the  earliest
period presented.

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  which  approximate  level  yield and is
adjusted for changes in prepayment estimates. Securities identified as available
for sale are carried at fair value with unrealized  gains and losses included in
shareholders' equity, net of deferred income taxes. Realized gains and losses on
sales of securities  are based upon the adjusted  cost of the specific  security
sold.

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;  however, 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.  BOK Financial  adopted Financial
Accounting  Standards  Board  Statement  No. 118,  "Accounting  by Creditors for
Impairment of a Loan - Income Recognition and Disclosures," in 1995. 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  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.

RESERVE FOR LOAN LOSSES

     The reserve for loan losses is  maintained  at a level that, in the opinion
of management,  is adequate to absorb losses inherent in the loan portfolio. The
adequacy of the reserve for loan losses is determined  by management  based upon
evaluation of the individual  credits in the loan portfolio,  historical  credit
losses,  anticipated economic conditions in BOK Financial's primary market areas
and other relevant  factors.  Beginning in 1994, BOK Financial adopted Financial
Accounting  Standards  Board  Statement  No. 114,  "Accounting  by Creditors for
Impairment of a Loan" ("FAS 114").  The  allowance for credit losses  related to
loans that are identified for evaluation in accordance  with 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.  The amount of impairment  determined in
accordance  with  FAS 114 did not  differ  materially  from  amounts  previously
provided.  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 allowance
for loan  losses  applicable  to these loans is  evaluated  in  accordance  with
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  which  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.

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, fair
value at date of foreclosure or current fair value less estimated selling costs.
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 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.

MORTGAGE SERVICING RIGHTS

     BOK Financial adopted Statement of Financial  Accounting Standards No. 122,
"Accounting  for Mortgage  Servicing  Rights" ("FAS 122"),  during 1995. FAS 122
requires,  among other things,  that  capitalized  mortgage  servicing rights be
carried  at the  lower of cost  less  accumulated  amortization  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 a risk-adjusted spread
over  U.S.  Treasury  rates,   which  is  the  assumed  market  rate  for  these
instruments.  Prepayment assumptions are based on industry consensus provided by
independent   reporting   sources.   Changes  in  current   interest  rates  may
significantly  affect these  assumptions by changing loan refinancing  activity.
Fair value for each  servicing  portfolio  acquired prior to the adoption of FAS
122 is based upon a single weighted average interest rate and remaining life for
that  portfolio.  Fair  value  for each  servicing  portfolio  acquired  and for
servicing  rights  originated  since the  adoption  of FAS 122 is based  upon an
interest rate stratification for each portfolio. Separate prepayment assumptions
are then used to project  net cash flows by  interest  rate  strata  within each
portfolio.  A valuation  allowance is provided when the  amortized  cost of each
portfolio or each interest rate strata exceeds the calculated fair value.

     Statement  of  Financial  Accounting  Standards  No. 125,  "Accounting  for
Transfers and Servicing of Financial Assets and  Extinguishment of Liabilities,"
("FAS 125") was issued  during 1996 and  becomes  effective  on January 1, 1997.
Among other things,  FAS 125 extends the requirement that a valuation  allowance
be provided for the difference  between the amortized  historical  cost and fair
value  of all  capitalized  servicing  rights  stratified  by  predominant  risk
characteristics   to  all  capitalized   servicing  rights.   Previously,   such
stratification  was required only for  servicing  rights  capitalized  after the
adoption of FAS 122.  The result of this change will be to further  increase the
volatility of earnings as the fair value of servicing rights react to changes in
interest rates and prepayment assumptions.

<PAGE> 27

     FAS  122  also  requires  that  originated  mortgage  servicing  rights  be
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 fair value of the originated servicing rights is
determined at closing based upon current market rates.

INTEREST RATE SWAPS AND FORWARD COMMITMENTS

     BOk uses  interest  rate swaps and forward  sales  contracts as part of its
interest rate risk management  strategy.  Interest rate swaps are used to modify
the interest expense of certain  long-term,  fixed rate certificates of deposit.
Amounts  payable  to or  receivable  from the  counterparties  are  reported  in
interest expense using the accrual method.  In the event of the early redemption
of hedged certificates of deposit,  any realized or unrealized gain or loss from
the swaps would be recognized in income coincident with the redemption.

     Forward sales contracts are used to hedge existing and anticipated loans in
conjunction  with  mortgage  banking   activities.   The  fair  value  of  these
instruments is included in determining  the adjustment of the loan held for sale
portfolio  to the lower of cost or market.  Gains or losses on closed  contracts
are recognized when the underlying assets are disposed.

     The cost of terminating  these contracts prior to their expiration dates is
expensed when incurred.

FEDERAL AND STATE INCOME TAXES

     Deferred  tax  assets and  liabilities  are  recognized  for the future tax
consequences   attributable  to  differences  between  the  financial  statement
carrying  values of assets  and  liabilities  and their  respective  tax  bases.
Deferred tax assets are reduced by a valuation allowance based upon management's
assessment of limitations on the use of certain  deferred tax assets pursuant to
income tax  regulations,  estimates of future taxable income,  and the amount of
previously paid taxes.

EMPLOYEE BENEFIT PLANS

     BOK Financial  sponsors various plans,  including a defined benefit pension
plan ("Pension Plan"), a qualified profit sharing plan ("Thrift Plan"), employee
health care plans and a post-retirement health care plan. Employer contributions
to the Thrift Plan, 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  accounts for its stock option plans under the  provisions of
APB 25,  "Accounting  for Stock  Issued to  Employees,"  and is also  subject to
certain  disclosures  as  required  under  Statement  of  Financial   Accounting
Standards No. 123, "Accounting for Stock-Based Compensation," in Note 12.
      
 FIDUCIARY SERVICES

     Fees and commissions on approximately $7.5 billion of assets managed by BOK
Financial  under various  fiduciary  arrangements  are recognized on the accrual
method.

EARNINGS PER SHARE

     Primary  earnings  per share are  computed by dividing  net income less the
value of preferred stock dividends  (including  dividends paid in common shares)
by the weighted  average  number of common  shares and common share  equivalents
outstanding.  The effect of stock  options  issued by BOK  Financial,  which are
considered  common share  equivalents,  on the average  number of common  shares
outstanding is determined by the treasury stock method.

     Fully diluted  earnings per share includes the maximum  dilutive  effect of
the  conversion  of  preferred  stock  at a ratio  of one  common  share  per 89
preferred shares.

     The average number of shares  outstanding has been restated for the effects
of the poolings-of-interests and stock dividends.

(2) ACQUISITIONS

     Since 1991, BOK Financial acquired deposits insured by the Savings and Loan
Insurance Fund ("SAIF") totaling approximately $843 million. In conjunction with
these  acquisitions,  core deposit  intangible assets which represent the future
earnings  potential of these funds,  were recorded.  In determining the value of
these core  deposit  intangible  assets,  assumptions  were made  regarding  the
returns which were expected to be earned over the costs which would be incurred,
including  interest expense,  processing costs and deposit  insurance  premiums.
During  1995,  the FDIC  made a  change  in  deposit  insurance  premiums  which
significantly  decreased  the value of  deposits  insured by SAIF.  The  premium
assessed on deposits  insured by the Bank  Insurance Fund ("BIF") was reduced to
three basis points  (.03%) while the premium  assessed on SAIF insured  deposits
remained at 23 basis points (.23%).  Legislation to resolve this  difference had
been  expected from  Congress at December 31, 1995.  However,  at the end of the
first quarter of 1996, the expected legislation had been removed from the agenda
and the  resolution of the  differential  between rates assessed on SAIF insured
deposits compared to BIF insured deposits was uncertain.  This  uncertainty,  in
addition to  heightened  competitive  pressures  caused the spreads  between the
actual returns and costs to decrease. These conditions caused the value of these
core deposit  intangible  assets to be impaired and a write down of $3.8 million
was recognized.

     In March 1997,  BOK Financial  paid $39.3 million to acquire First TexCorp,
Inc. and its subsidiary,  First Texas Bank, in Dallas, Texas. Total consolidated
assets and net assets of First  TexCorp,  Inc.  were  $141.9  million  and $19.7
million,  respectively,  at December 31, 1996. The acquisition will be accounted
for as a purchase.

     In  February  1997,  BOK  Financial  paid $39.0  million  and issued  notes
totaling  $11.0  million  to  acquire  Park  Cities  Bancshares,  Inc.  and  its
subsidiary,  First  National  Bank of  Park  Cities,  in  Dallas,  Texas.  Total
consolidated  assets and net assets of Park Cities Bancshares,  Inc. were $225.9
million and $19.1 million,  respectively,  at December 31, 1996. The acquisition
will be accounted for as a purchase.

     On November 14, 1994, BOK Financial issued 1,380,017 common shares to merge
with Citizens  Holding Company and its  subsidiaries,  Citizens Bank of Muskogee
and Citizens Bank of Northwest Arkansas, in a pooling-of-interests.

     BOk paid $11.7  million,  on May 2, 1994, to acquire Plaza  National  Bank,
Bartlesville,  Oklahoma; paid $6.1 million, on June 13, 1994, for Texas Commerce
Trust Company-Sherman  National  Association,  a national association limited to
trust  powers  only;  and paid $8.2  million,  on October  7,  1994,  to acquire
Northwest Bank of Enid, Enid, Oklahoma.

     During  April  1991,  BOk sold to BOK  Financial's  principal  shareholder,
George B.  Kaiser  ("Kaiser"),  and related  business  entities  certain  loans,
repossessed  real  estate  and  the  rights  to  future  recoveries  on  certain
charge-offs.  Recoveries  collected by BOk and paid to Kaiser were $3.3 million,
$1.4 million and $2.4 million for 1996, 1995 and 1994, respectively.

     Effective  December 20, 1995,  BOK  Financial  adopted the  provisions of a
Financial  Accounting  Standards  Board special report on Statement of Financial
Accounting  Standards No. 115  "Accounting  for Certain  Investments in Debt and
Equity Securities", which affects the securities portfolio.

     This report permitted a one-time opportunity to sell or transfer securities
from the  investment  category to the available  for sale or trading  categories
without     tainting     the     remaining     portfolio.      BOK     Financial
transferred-mortgage-backed and municipal securities with a total amortized cost
of $788.5 million and a net unrealized  loss of $4.0 million from the investment
category  to   available   for  sale  in   response  to  the  more   restrictive
interpretation of FAS 115 included in this special report.

     Effective  November  14,  1994,  certain  securities  obtained  through the
acquisition  of  Citizens  Holding  Company  were  transferred  from the held to
maturity  portfolio to available for sale. The transfer  served to structure the
acquired  portfolio  in  accordance  with BOK  Financial's  existing  investment
strategy.  The securities transferred had a total amortized cost of $6.7 million
and a net unrealized loss of $184 thousand as of the date of transfer.

     Securities  with  amortized  costs of $1.0  billion  and $986.5  million at
December  31, 1996 and 1995,  respectively,  were  pledged to secure  securities
repurchase agreements,  public and trust funds on deposit and for other purposes
as required by law.

     Substantially  all of the  commercial  and  consumer  loan  portfolios  and
approximately  77% of the residential  mortgage loan portfolio  (excluding loans
held for sale) are loans to businesses and  individuals in Oklahoma or Northwest
Arkansas.  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 $217.1 million,  or 9% of total loans.  Other notable segments
include  wholesale/retail,  $166.1 million;  manufacturing,  $137.5 million; and
agriculture, $109.3 million.
   
  Commercial real estate loans are primarily secured by properties located in
the Tulsa or Oklahoma City, Oklahoma metropolitan areas. The major components of
these properties are multifamily residences,  $146.2 million; retail facilities,
$60.8 million;  office  buildings,  $82.3 million;  hotels,  $70.6 million;  and
medical/nursing facilities, $70.3 million.

(7)  MORTGAGE BANKING ACTIVITIES

     BOK  Financial  has  engaged in  mortgage-banking  activities  through  its
subsidiary,  BancOklahoma  Mortgage Corp.  ("BOMC").  Effective January 1, 1997,
these mortgage banking activities were transferred to BOk.  Residential mortgage
loans held for sale  totaled  $95.3  million and $72.4  million and  outstanding
mortgage  loan   commitments   totaled  $148.2   million  and  $125.4   million,
respectively,  at December  31, 1996 and 1995.  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 which will be delivered in the next 60
to 90 days.  At December  31,  1996,  forward  sales  contracts  totaled  $168.1
million. 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 forward sales  contracts.  At December 31, 1996, BOMC owned the rights
to service 83,418  mortgage loans with  outstanding  principal  balances of $5.9
billion,  including  $243 million  serviced for BOk, and held related  funds for
investors and borrowers of $77.2 million. The weighted average interest rate and
remaining term was 7.70% and 281 months, respectively.  Mortgage loans sold with
recourse  totaled $9.4 million at December 31, 1996. At December 31, 1995,  BOMC
owned the rights to service mortgage loans with outstanding  principal  balances
of $5.4  billion and held related  funds for  investors  and  borrowers of $76.6
million.

- --------------------------------------------------------------------------------
    
 Fair value is  determined  by  discounting  the  projected  net cash flows.
Significant assumptions are:
     Discount rate - Risk adjusted  spread over U.S.  Treasury rates for similar
          remaining terms, ranging from 10.71% to 10.95%.
     Prepayment rate - Industry consensus prepayment estimates ranging from 6.8%
          to 16.4% from an  independent  reporting  source  based upon  interest
          rate, original term and loan type.
     Loan servicing  costs - $50 per  conventional  loan and $60 per  government
          insured loan.

     During  the first  quarter  of 1994,  management  discovered  that  Lenders
Mortgage  Services,  Inc.  ("Lenders"),  an  originator of loans from which BOMC
purchased  mortgage  loans,  had not  paid off  existing  mortgages  on  certain
refinancing loans purchased by BOMC, primarily in 1994. Involuntary  proceedings
were commenced against Lenders under Chapter 7 of the U.S. Bankruptcy Code and a
Trustee was appointed.  Lenders will not be able to perform under the repurchase
provision of the loan purchase agreement. Management is pursuing recoveries from
various parties; however, any such recoveries are uncertain at this time. Pretax
charges  of $5.2  million  were  recognized  in  1994  based  upon  management's
evaluation of information currently available.

at  December  31,  1996  and  1995  were  $560.0  million  and  $486.2  million,
respectively.

     Time  deposits  expected  to  mature  in less  than one  year are  $1,047.0
million, in one to five years are $460.8 million, and in over five years are $.5
million.

     Interest  expense on time deposits  during 1996 and 1995 was reduced by net
income from interest rate swaps of $1.4 million and $.9 million, respectively.

     The  acquisition  of BOk by BOK  Financial  on June 7, 1991  resulted  in a
change of ownership, which significantly limited the utilization of built-in and
net  operating  loss  carryforwards.  Consequently,  and  due to the  expiration
periods  and the  timing of the  anticipated  reversal  of  built-in  losses,  a
valuation  allowance  had been  recorded.  The  factors  used by  management  to
determine the amount of valuation  allowance included  limitations on the use of
certain  deferred tax assets  pursuant to income tax  regulations,  estimates of
future  taxable  income,  the amount of previously  paid income taxes,  and to a
lesser extent,  tax  strategies.  Due to the expiration in 1996 of the five-year
period during which the utilization of currently  recognized built-in losses was
limited and the full utilization of all recognized  built-in loss  carryforwards
for income tax purposes as of December 31, 1996,  the  valuation  allowance  has
been  eliminated.  BOk and BOK  Financial  are  currently  under an audit by the
Internal Revenue Service for 1992 and 1993,  respectively.  The ultimate outcome
of this audit cannot be  determined  with any  certainty at this time.  However,
management expects no material adverse impact on the financial statements.

     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 Plan, a defined contribution plan, are
matched by BOK  Financial  up to four percent of base  compensation,  based upon
years of service.  Participants may direct the investment 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 Plan
totaled $1.2  million,  $1.5  million and $1.2 million for 1996,  1995 and 1994,
respectively.

     BOK Financial 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 consist primarily of shares in
a cash management  fund.  Liability for the  post-retirement  plan is limited to
current retirees and certain employees currently age 60 or older.

     A 1% increase in the assumed  medical  inflation  rate would  increase  the
accumulated  post-retirement  benefit  obligation by approximately $182 thousand
and would increase post-retirement benefit cost by $15 thousand.

     Under various performance incentive plans,  participating  employees may be
granted  awards  based on defined  formulas  or other  criteria.  Earnings  were
charged  $7.5 million in 1996,  $5.3 million in 1995,  and $5.0 million in 1994,
for such awards.

(1)  Exercise price for options  outstanding  under the 1994 plan as of December
     31, 1996 was $19.80 - $23.83. The  weighted-average  remaining  contractual
     life of those options is 5.9 years.
- --------------------------------------------------------------------------------

     Under APB 25 no  compensation  expense is  recognized  at the date of grant
since the exercise  price of BOK  Financial's  employee  stock option equals the
market price of the underlying stock on the date of grant.

     FASB Statement No. 123, "Accounting for Stock-Based Compensation," requires
disclosure of pro forma information  regarding net income and earnings per share
as if BOK Financial  accounted for employee stock options granted  subsequent to
December 31, 1994 under the fair value method of the 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 for 1995 and 1996, respectively: average risk-free interest rates of
6.04% and 6.10%;  a dividend yield of zero;  volatility  factors of the expected
market price of BOK  Financial's  common stock of .190;  and a  weighted-average
expected life of the options of eight years.
       
     The  Black-Scholes   option  valuation  model  was  developed  for  use  in
estimating the fair value of traded  options which 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.  The following
table  represents  the  required  pro  forma  disclosures  for  options  granted
subsequent to December 31, 1994:

                                              1996(1)      1995(1)
                                            ----------- -----------
        Pro forma net income                  $53,748     $49,196
        Pro forma earnings per share:
            Primary                             $2.46       $2.25
            Fully diluted                        2.22        2.05

(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.

(13) 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  at  the  end  of  the   thirty-seventh  and
forty-seventh years. Annual base rent is $3.1 million. BOk subleases portions of
its space for annual rents of $392  thousand  each year through  2000.  Net rent
expense on this lease was $2.7  million in 1996,  $2.6  million in 1995 and $2.1
million in 1994.  Total rent expense for BOK Financial was $6.9 million in 1996,
$6.7 million in 1995 and $6.0 million in 1994.

     At December 31, 1996,  the future  minimum lease payments for equipment and
premises  under  operating  leases were as follows:  $6.8 million in 1997,  $6.7
million in 1998,  $6.6 million in 1999,  $6.5  million in 2000,  $6.2 million in
2001 and a total of $106.9 million thereafter.

     BOk and The Williams Companies,  Inc. guaranteed 30 percent and 70 percent,
respectively,  of the $18.7  million  debt,  which  matures  May 15,  2007,  and
operating  deficit  of two  parking  facilities  operated  by the Tulsa  Parking
Authority.  Total  expense  related  to this  guarantee  was zero in 1996,  $100
thousand in 1995 and zero in 1994.

     The Federal Reserve Bank requires member banks to maintain  certain minimum
average cash balances.  These balances were approximately $70.8 million for 1996
and $86.0 million for 1995.


(14) 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, 1996, outstanding  commitments
totaled $899.8  million.  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.  At  December  31,  1996,  outstanding
standby letters of credit totaled $91.7 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,  1996,  outstanding  commercial  letters of credit
totaled $4.5 million.

     BOK  Financial  uses  interest  rate  swaps,  a form  of  off-balance-sheet
derivative  product,  in managing its interest  rate risk.  These swaps are used
primarily to more closely  match the interest paid on certain  long-term,  fixed
rate  certificates  of deposit with earning  assets.  BOK Financial  agrees with
other  parties to  exchange,  at specified  intervals,  the  difference  between
fixed-rate  and  floating-rate  interest  amounts  calculated by reference to an
agreed-upon  notional  amount.  At December 31, 1996, the notional amount of BOK
Financial's  interest  rate swaps  totaled  $101.5  million with related  credit
exposure,  represented  by the fair  value of the  contracts,  of $1.6  million.
During 1996 and 1995,  income from the swaps  exceeded costs by $1.4 million and
$.9 million, respectively, which reduced interest expense on deposits. Scheduled
repricing periods for the swaps are as follows (in thousands):

                   31-90     91-365      Over
                   days       days      1 year     Total

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

     Swap contracts with notional amounts of $63 million,  $22 million and $16.5
million expire in 1998, 1999 and 2006, respectively. The expiration dates of the
swap contracts are designed to match the estimated  maturity dates of the hedged
certificates of deposit.

     BOK Financial utilized  securities forward sales contracts  associated with
its mortgage banking activities as described in Note 7.

(15) 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 89 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 $15.0 million.  During 1996, 1995 and
1994,  69,672  shares,  69,959 shares and 65,279  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.  Kaiser owns substantially all Series A
Preferred  Stock.  These  shares were valued at $1.5  million in 1996,  1995 and
1994,  based on average market price,  as defined,  for a 65 business day period
preceding declaration.

     During 1995,  102 nonvoting  units in an entity owned by BOk were issued to
various  officers of 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.

COMMON STOCK
     Common stock consists of 2.5 billion authorized shares,  $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.

     During 1996, 1995 and 1994, 3% dividends payable in shares of BOK Financial
common  stock were  declared  and paid.  The shares  issued were valued at $16.5
million,  $12.8 million and $12.3  million,  respectively,  based on the average
closing bid/ask prices on the day preceding declaration.

SUBSIDIARY BANKS
     The amounts of dividends which 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, 1996, BOK Financial's  subsidiary
banks  could  declare  dividends  up to $21  million  without  prior  regulatory
approval.  The  subsidiary  banks  declared and paid dividends of $31 million in
1996, and none in 1995 or 1994.

     Loans to a single  affiliate  may not exceed 10.0  percent and loans to all
affiliates  may not exceed 20.0 percent of  unimpaired  capital and surplus,  as
defined. Additionally, loans to affiliates must be fully secured. As of December
31,  1996 and  1995,  these  loans  totaled  $12.4  million  and  $4.6  million,
respectively.  Total loan  commitments  to  affiliates at December 31, 1996 were
$22.7 million.

REGULATORY CAPITAL
     Financial  institutions are considered to be "well capitalized" pursuant to
the  Federal  Deposit  Insurance  Corporation  Improvement  Act of 1991 if their
Leverage,  Tier  1 and  Total  Capital  ratios  are at  least  5%,  6% and  10%,
respectively.  As shown in Table 13, BOK  Financial's  capital ratios exceed the
regulatory definition of well capitalized.  The capital ratios for BOk and CBNWA
are substantially the same as BOK Financial's ratios.

     As defined by  regulations,  Tier 1 capital  consists  primarily  of common
stockholders'  equity less certain  intangible  assets.  Total capital  consists
primarily of Tier 1 capital plus preferred stock, subordinated debt and reserves
for loan losses, subject to certain limitations.

                                           December 31,

     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

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 $9.9 million and $12.7  million at December 31, 1996
and 1995, respectively.

     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.  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 interest rate
swaps  are  based on  pricing  models  using  current  assumptions  to arrive at
replacement  cost. The fair values of these  off-balance-sheet  instruments were
not  significant  at  December  31,  1996 and 1995.  Residential  mortgage  loan
commitments  are included in  determining  the fair value of the mortgage  loans
held for sale.
