                         General Development of Business

Developments  relating to  individual  aspects of the business of BOK  Financial
Corporation ("BOK Financial") are described below.  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 10-24) in
BOK Financial's  1999 Annual Report to Shareholders.  Information  regarding BOK
Financial's  acquisitions  is  incorporated  by reference to Note 2 of "Notes to
Consolidated Financial Statements" (page 34 - 35) in BOK Financial's 1999 Annual
Report to Shareholders.

                        Narrative Description of Business

BOK Financial is a bank holding company whose activities are limited by the Bank
Holding  Company  Act  of  1956,  as  amended   ("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
Bank of Oklahoma,  N.A. ("BOk"),  Bank of Texas, N.A., Bank of Albuquerque N.A.,
and Bank of Arkansas,  N.A. Other  significant  operating  subsidiaries  include
BOSC, Inc., which is a full-service  securities firm with specialized  expertise
in public and municipal finance and private placements, and BOK Capital Services
Corporation,  which  provides  leasing and  mezzanine  financing.  Other nonbank
subsidiary  operations  are  not  significant.  As of  December  31,  1999,  BOK
Financial and its subsidiaries had 3,101 full-time equivalent employees.

                                Industry Segments

BOK Financial operates four principal lines of business under its BOk franchise:
corporate  banking,  consumer banking,  mortgage banking and trust services.  It
also operates a fifth principal line of business, regional banks, which includes
banking  functions for Bank of Albuquerque,  Bank of Arkansas and Bank of Texas.
These five principal lines of business combined account for approximately 86% of
total revenue.  Discussion of these  principal lines of business is incorporated
by reference to Lines of Business in "Management's  Assessment of Operations and
Financial  Condition  " (pages 13 - 15) and Note 17 of  "Notes  to  Consolidated
Financial  Statements"  (pages 48 - 51) in BOK Financial's 1999 Annual Report to
Shareholders.

                                   Competition

The  banking  industry  in  each  of our  markets  is  highly  competitive.  BOK
Financial, through four subsidiary banks, competes with other banks in obtaining
deposits, making loans and providing additional services related to banking.

BOk is the  largest  banking  subsidiary  of BOK  Financial.  It has the largest
market  share in Oklahoma and a leading  market  position in eight of the eleven
Oklahoma  counties in which it operates.  BOk competes  with two  super-regional
banks and numerous locally owned banks in both Tulsa and Oklahoma City areas, as
well as several  locally owned small community banks in every other community in
which we do business throughout the rest of the state.

BOK Financial  competes in the Dallas-Ft.  Worth combined  metropolitan area, in
the  Albuquerque,  New Mexico  market,  and in  Fayetteville,  Arkansas  through
subsidiary   banks.   Bank  of  Texas  competes   against   numerous   financial
institutions,  including  some of the largest in the U.S. Bank of Texas's market
share is approximately  2%, including three 1999 Texas bank  acquisitions  which
will be merged into Bank of Texas in 2000. Bank of Albuquerque has a number four
market  share  position  in the City of  Albuquerque  behind two  super-regional
competitors followed by several  locally-owned  smaller community banks. Bank of
Arkansas operates as a community bank serving Benton and Washington  counties in
Arkansas.

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 regional
banking environment in our markets.

                           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,  Bank  of  Texas,  Bank  of
Albuquerque, or Bank of Arkansas.

<PAGE>

                                 BOK Financial

As a bank holding company, BOK Financial is subject to regulation under the BHCA
(as amended by the Financial  Services  Modernization Act or  Gramm-Leach-Bliley
Act) and to supervision by the Board of Governors of the Federal  Reserve System
(the "Reserve  Board").  Under the BHCA,  BOK  Financial  files 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 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 pay-out, nonoperating basis.

A bank holding company 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, 1999, BOK Financial's  Leverage,  Tier 1 and
Total Capital ratios were 5.92%, 7.27% and 10.72%, respectively.

                               Bank Subsidiaries

BOk,  Bank of Texas,  Bank of  Albuquerque,  and Bank of Arkansas  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.

Bank  of  Arkansas  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.

Applicable  federal  statutes and  regulations  require  national  banks to meet
certain leverage and risk-based capital requirements.  At December 31, 1999, all
of BOK Financial  Corporation's leverage and risk-based capital ratios were well
above the required minimum ratios.  Additional  discussion  regarding regulatory
capital  is  incorporated  by  reference  to Note 15 of "Notes  to  Consolidated
Financial  Statements"  (page 46 - 47) in BOK Financial's  1999 Annual Report to
Shareholders.

                   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.

                               Foreign Operations

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

To Our Shareholders,
Customers, Employees and Friends:

     BOK  Financial  Corporation  had another  landmark year in 1999 - a year of
continued  financial  progress,  broader  expansion  into new  markets,  further
penetration  into current markets,  and continued  commitment to the communities
and customers we serve.

     We  reported  growth in earnings  for the eighth  consecutive  year,  while
growing our assets by 23 percent from year-end 1998 to year-end  1999.(5) Annual
earnings  were  $89.2  million,  representing  a 12  percent  increase  over the
previous  year.  Earnings  per share were  $1.60,  compared  to $1.43 last year.
Tangible  net income per  diluted  share grew 16 percent to $1.83 per  share.(6)
Assets of the company now stand at $8.4 billion,  reflecting our position as one
of the region's leading bank holding companies.

     Net interest revenue after provision for loan losses was up 28 percent over
1998. Fees and commissions  increased 12 percent.  The company achieved a return
on average equity of 16.45 percent,  while posting a 12 percent gain in earnings
per share.

     Our growth  across  the region in 1999 was  bolstered  by  acquisitions  in
high-growth markets. Mid-Cities National Bank in Hurst, Texas, gave us our first
location in Tarrant  County,  near Fort Worth.  Swiss  Avenue State Bank gave us
three more key locations in Dallas,  each  adjacent to a major  medical  center.
Canyon Creek  National Bank  positioned  us in rapidly  growing  Richardson  and
McKinney.  We  now  have a  network  of 13  locations  from  Dallas-Fort  Worth,
northward to Sherman.  The three new banks have combined assets of $380 million,
bringing our total assets in Texas to $1.2 billion.

     Meanwhile,  we continued to expand in our home state of Oklahoma. We merged
with First  Muskogee  Bancshares,  making us the clear market  leader in eastern
Oklahoma. And we acquired another Kansas City area mortgage firm, First Mortgage
Investment  Company.  We now have mortgage  offices in Lee's  Summit,  Missouri;
Topeka, Kansas; and Lenexa, Kansas.
<PAGE> 2

     In addition to our internal  growth,  these  acquisitions  mean our company
continues  to evolve  from  primarily  an  Oklahoma  bank to a regional  holding
company with successful banking operations in multiple states. Our Bank of Texas
franchise  now  represents  14 percent of the  company's  assets,  while Bank of
Albuquerque comprises 11 percent. Bank of Arkansas, while smaller than the other
banks, achieved substantial growth in 1999 as well.

     In addition to this  geographic  diversity,  our sources of fee income also
remain diverse.  We have historically ranked among the highest in our peer group
in the  proportion of  non-interest  revenue to total  revenue,  and 1999 was no
exception. Fee-based lines of business comprised 43 percent of total revenue. We
saw growth of 34  percent in  transaction  card  revenue,  21 percent in service
charges and fees on deposits,  and 17 percent in trust fees. Overall,  fee-based
revenue grew by 12 percent. We expect revenue from fee-based  businesses to grow
as we introduce our proven fee-based products to our new customers.

     Our strategy for continued growth remains  unchanged.  We have demonstrated
our  ability  to  compete  against   nationally   prominent  banks  by  offering
sophisticated  products  and  services  delivered  in  a  style  reflecting  our
community  bank  roots.  We know our  customers,  and seek to provide  them with
banking resources tailored to their specific needs.

     The Internet is becoming an increasingly vital delivery channel for us. Our
web sites are constantly adding more valuable  services for our customers.  Last
year  alone  we added  online  investing  and an  improved  small-business  cash
management  system.  We  also  established  an  online  system  enabling  401(k)
participants  to  access  their  accounts,   and  started   accepting   mortgage
applications  online.  We encourage you as shareholders to visit our web site at
www.bokf.com for current stock quotes, news releases and more.

     We will continue to boost our presence in Oklahoma,  Texas,  New Mexico and
Arkansas by reaching new customers and pinpointing strategic acquisitions. As we
grow, we will maintain our competitive  advantage by delivering superior service
to our  customers.  To help achieve this,  we will be moving 700 employees  this
year to our new  state-of-the-art  operations  and  technology  center in Tulsa,
which will improve work flow and accelerate processes while giving us a platform
for continued growth and greater cost efficiencies.

     We look  forward  to future  success,  as we build on our  track  record of
excellent financial  performance,  market leadership,  and superior customer and
community service.

     As always, we appreciate your support and your business.

Our proven strategy for growth.

     BOK Financial  Corporation  continued its historical  pattern of growth and
progress  during 1999. We have been able to achieve this progress by following a
proven strategy that emphasizes four key points.
     First,  reflecting  our  community  bank  roots,  we place a great  deal of
emphasis on knowing our customers and  delivering  superior  service.  Combining
that service commitment with the resources and products of a national bank makes
a winning combination, and that's where we have found our niche - as a bank with
nationally competitive products and community bank service.
     Second, we continue to extend our leadership  position in our home state of
Oklahoma, ranking No. 1 in commercial banking, consumer banking, trust services,
mortgage lending, and electronic funds transfer. With 69 locations statewide and
counting, we are easily the most visible, most accessible bank in Oklahoma.  And
across the board,  our staff includes the most experienced bank personnel in the
state - people who know their  communities and customers,  and understand  their
markets.
     With such a successful  track  record in our home state,  it makes sense to
duplicate it in our other markets,  which is our third objective:  to expand our
presence in high-growth markets in contiguous states. Our primary emphasis is to
grow our current markets,  leveraging from our platforms in Arkansas, New Mexico
and Texas. Simultaneously, we plan to continue implementing our successful model
for building fee-based growth in acquired banks that have historically relied on
interest revenue as their primary source of income.
     Our  final  objective  is to focus on  expense  control,  productivity  and
efficiency.  In  2000,  we're  moving  our  operations  functions  into  the new
Technology  Center in Tulsa,  enabling us to make vast improvements in processes
and  efficiencies.  As  always,  our goal is to  maintain  service  quality  and
reliability at a level that provides a clear advantage over our competitors.
     If 1999 is any measure,  we are  successfully  executing this  four-pronged
strategy.  BOK Financial  Corporation's  assets grew by 23 percent in 1999, from
$6.8 billion(5) to $8.4 billion. Our assets have doubled in the last five years.
Annual earnings were up 12 percent in 1999,  marking our eighth consecutive year
of earnings growth.

Our continued expansion throughout the region.

     A key  ingredient  to our recent and  future  success is our market  growth
outside of Oklahoma. Just seven years ago, we were exclusively an Oklahoma bank.
Our  expansion  has been  steady  and  diverse,  while we have also  upheld  our
standards of quality.
     Last year was no exception.  Loans outside of Oklahoma nearly doubled, from
$655 million to $1.2 billion.  Our growth is coming from non-lending  sources as
well,  as we introduce our  successful  fee-based  business  lines into acquired
banks that have traditionally relied almost exclusively on interest income.

Texas

     Our move into the Texas market began with a series of small steps  starting
in 1994,  when we acquired a trust  company in Sherman,  Texas.  We acquired two
Dallas banks in 1997, and since then, our progress has remained steady.
         Last year, we completed three  acquisitions  in the  Dallas-Fort  Worth
Metroplex,  bringing our total locations in Texas to 13. Texas now represents 14
percent of the  company's  total assets at $1.2  billion.  Bank of Texas in 1999
produced an  impressive  $260 million  increase in loans.  Trust assets in Texas
grew by 57 percent,  and trust fees  increased by 26 percent.  Our  expansion is
spreading  throughout  north  Texas,  and in  1999 we  opened  our  first  Texas
supermarket bank, in Sherman.  We also opened a mortgage  origination  office in
Dallas, and will continue  developing our services in private banking,  consumer
banking,  retail investments and trust. We have made tremendous strides in Texas
in the last few years,  and have every  intention  for this pattern of growth to
continue.

New Mexico

     Our New Mexico  franchise  was another  story of  progress in 1999.  At the
close of 1998,  Bank of Albuquerque  was a newly acquired bank with $500 million
in assets. Since then we have significantly broadened the bank's appeal, growing
from a  consumer-oriented  bank to one that  includes  trust,  private  banking,
mortgage lending, brokerage services and commercial banking.
     Bank of  Albuquerque  has also been  attracting  the  attention of the most
experienced  bankers in the market.  We recruited  talented  people with lengthy
records of success in the area, further  positioning  ourselves to gain momentum
and  continue  growing.  Our strategy of adding top people and products - proven
successful in our other markets - is working at Bank of Albuquerque.

Arkansas

     Our Arkansas operation,  now in its sixth year, showed its best performance
yet, and its services continue to expand.  Our Little Rock-based  brokerage unit
continues  to  thrive,  with  27  representatives   handling  a  full  range  of
institutional  investments,  and corporate and public finance underwriting.  Our
mortgage  operation  now  includes  offices  in Little  Rock,  Fayetteville  and
Bentonville.  We opened a loan production office in Little Rock during 1999, and
also  developed  several  significant  relationships  in Fort Smith,  a sizeable
Arkansas expansion market.
     The year also proved to be  financially  successful  for Bank of  Arkansas,
with growth in loans and net interest income of 24 and 21 percent, respectively.
Fee-income picked up as well,  growing by 20 percent,  led by increases in trust
and retail investments.

Oklahoma

     While our growth continues in contiguous states, we remain steadfast in our
commitment to our home state.  In fact,  our Oklahoma  business is thriving.  In
1999 our Oklahoma lenders produced $534 million of new loans, ending the year at
$3.4 billion.  We acquired First  National Bank of Muskogee,  more than doubling
our size in the Muskogee market and making us the clear market leader in eastern
Oklahoma.  We opened four new  supermarket  locations in Oklahoma,  bringing our
total supermarket branches to 28 - including a branch in every Albertsons in the
Tulsa  area.
     Our recent  success -  throughout  the  region - has added to the  economic
vitality of our home state. Our Oklahoma employment has more than doubled during
the '90s,  as our  growth  into a regional  banking  firm has made us one of the
leading employers in the state.

Elsewhere

     We remain interested in gaining a foothold in new, high-growth markets, and
continue looking for opportunities that meet the criteria of our strategic plan.
In 1999, we acquired a successful mortgage company which expanded our operations
in the Kansas City area and gave us an entry into the Topeka market.
<PAGE> 6

Our diversity of income sources.

     A major  component of our recent success can be attributed to the diversity
of our sources of income. While we maintain a solid, balanced loan portfolio, we
have  also  historically  ranked  among  the  highest  in our peer  group in the
proportion of non-interest revenue to total revenue.

Fee-based Lines of Business

     In 1999, 43 percent of our revenue came from fee-based  businesses  despite
our acquisition of new banks with lower fee-income proportion. In all, fee-based
revenues grew by 12 percent last year,  and were balanced among several lines of
business.
     Eighteen percent of all fee-based income came from our transaction card and
electronic funds transfer  network.  Transaction card revenue grew by 34 percent
in 1999, and our TransFund  unit's Visa Check Card was used to make 30.7 million
purchases,  an  increase  of 35  percent.  TransFund  is now  the  20th  largest
electronic  funds  transfer  network in the U.S.,  with more than 1,000 machines
installed in an eight-state area,  providing services to more than 270 financial
institutions and 1.2 million cardholders
     Trust  revenues made up 19 percent of our fee-based  income in 1999.  Trust
revenues  grew by 17 percent,  including a 26 percent  increase in Texas  alone,
with personal  trust in Oklahoma  City  doubling in the last two years.  Overall
trust assets are now $17.2 billion, up from $14.4 billion last year.
     Our  trust  line-up  includes  our  highly  successful   employee  benefits
products,  which serve more than 100,000 defined contribution plan participants.
Our  self-directed  401(k) option attracted clients from New York to California.
The  American  Performance  Fund,  a mutual  fund  family  managed  by our trust
investments  group,  continues  to be one of the  most  successful  mutual  fund
families in the United States.  At year-end  1999,  assets for the fund stood at
$1.8 billion - an increase of $264 million from a year before,  for a gain of 17
percent.  In addition,  eight of the nine American  Performance  funds ranked by
Lipper outperformed their respective peer group for the three-year period ending
December 31, 1999.
     Twenty  percent  of our  fee-based  revenue  in 1999 was  generated  by our
mortgage  division.  At year-end,  the servicing  portfolio stood at $7 billion,
servicing  more than 94,000 loans in all 50 states and the District of Columbia.
According to the latest available figures,  our mortgage servicing  portfolio is
the 39th largest in the United States.
     We are the No. 1 mortgage originator in Oklahoma, including the top ranking
in Oklahoma City and Tulsa. Within our own system, Oklahoma comprises 73 percent
of our total mortgage originations,  but other states are gaining ground. Kansas
and  Arkansas  each hold about 10 percent  of our total  business.  And with new
offices  in New  Mexico  and  Texas,  we're  sure to see an even  more  balanced
distribution in 2000 and beyond.
     BOSC Inc., our securities unit,  initiated  several  structural  changes in
1999 and is now a full-service,  regional  brokerage and public finance firm. By
consolidating  inter-firm trading functions,  expanding  securities trading, and
unifying  management  accounting and reporting systems,  BOSC has created a more
efficient, effective way of meeting the needs of public entities, not-for-profit
enterprises, corporations, and individual investors.
<PAGE> 7


     Nine percent of all our fee-based  revenues in 1999 came from our brokerage
units.  Our  retail  investments  group  opened  over  9,000 new  accounts,  and
conducted nearly 70,000 transactions totaling $718 million.
     On the public  finance  side,  the Oppenheim  division is Oklahoma's  clear
leader in underwriting  and financial  advisory  services,  and its revenues for
1999 were $5.2 million.
     Service  charges and fees for our nationally  competitive  cash  management
products comprised the fifth source of our diverse fee-based revenue. We will be
introducing a number of new cash management products during 2000, but 1999 was a
successful year in itself.  Growth from these services was 21 percent, and these
services made up 22 percent of total fee-based revenues.

Lending

     Our loan portfolio is still strong, diverse and growing, with total loans -
excluding acquisitions - up 23 percent. Including acquisitions,  loans increased
nearly $1 billion during the year, rising 27 percent.
     Our  traditional  strength  has been in lending to small and  middle-market
businesses,  and we have found this expertise  welcomed in our new markets.  All
segments of  commercial  loans grew,  showing an overall  increase of 34 percent
over year-end 1998.
     Our credit quality remains strong.  In fact, we had net recoveries from the
commercial loan portfolio in 1999. At year-end our reserve for loan losses stood
at 1.66 percent of total loans.

Our advances in technology and service delivery.


     One of the key components to maintaining our competitive advantage has been
to make our  products  convenient  and easy to use,  while  also  improving  our
service quality.
     Several  initiatives  have taken place - and more are underway - to achieve
this  goal.  In  1999,  the  further  expansion  of  our  web  sites  and  other
Internet-based  applications allowed us to improve upon our delivery of services
and products.  All four of our banks now have their own web sites,  which can be
accessed on the Internet by typing the name of the individual bank (for example,
www.bankoftexas.com), or through our corporate site at www.bokf.com.
     This delivery  channel has been widely  accepted by our  customers.  Online
banking IDs and online consumer loan  applications each grew by 400 percent last
year. We started opening online consumer deposit accounts in Oklahoma,  and also
began taking mortgage applications online.
     Our 24-hour call  center,  ExpressBank,  also  continues to be very popular
among  customers.  Twenty-five  percent of all consumer loan  applications  were
initiated through  ExpressBank,  which services customers in all four states. In
1999, ExpressBank handled 6 million calls.
<PAGE> 8

     We also launched  online  brokerage for retail clients,  offering  Internet
delivery of quotes, research,  account data and more. The use of such technology
positions  our  brokerage  units to improve  efficiency  as our sales  force and
volumes expand.
     On the commercial  banking side,  several new  Internet-based  products are
making it easier than ever for our commercial  clients to transfer  funds,  plot
cash flow, and gain access to vital  information.  Small businesses now have the
Business  Express Web,  allowing  customers to obtain  balance  information  and
initiate transactions over the Internet. A similar product for larger businesses
will be  enhanced  with  Internet  capability  in  2000,  and we will  introduce
electronic  bill  presentment,  which  allows  businesses  to  present  bills to
consumers for review and payment over the Internet.  We are also making advances
in image technology.  For example,  we are implementing an image lockbox service
that will enable our  customers to retrieve  images of documents  from a compact
disc rather than from paper-based  records. In turn, they will be able to better
serve their customers' needs.
     Likewise,  customers of our trust  division are reaping great benefits from
advances in technology.  Over one-third of our clients' 401(k)  participants now
use Internet-based  technology to access their accounts. That number is expected
to more than double by mid-2000.

Our improving efficiencies.

         One of our biggest steps in improving efficiency will occur in 2000, as
we begin moving our service  operations into a new Technology  Center. The first
units  will  move  in June  2000.  The  center  should  be  fully  occupied  and
operational  by December 2000.  This will enable us to make numerous  efficiency
improvements to service quality.  It will improve our communications  capability
by incorporating the latest technologies in the industry, such as bringing fiber
optics to every workstation and improving performance of the network. We'll also
increase capacity and improve back-up capabilities for business resumption.
         But above  all,  the new  Technology  Center  allows  us to  streamline
workflow,  improve control and reduce  processing time, while lowering costs. By
configuring the layout to optimize processes,  the center allows us the capacity
to expand and grow, as our  operations  continue  growing - a luxury we have not
enjoyed in our present facilities.
         Finally, the much-anticipated Y2K came and went without fanfare, thanks
to the efforts of many people in our  organization.  It was a non-event,  but it
didn't happen by accident.  Our preparations proved to be successful - every bit
of work,  time and money  spent was well worth it, and full  credit  goes to our
staff. Their diligence, persistence and extra work all paid off.

MANAGEMENT'S ASSESSMENT OF OPERATIONS AND FINANCIAL CONDITION

     BOK Financial  Corporation ("BOK Financial") is a bank holding company that
offers full service banking in Oklahoma, Northwest Arkansas, North Texas and New
Mexico.  BOK  Financial's  principal  subsidiaries  are Bank of Oklahoma,  N.A.,
("BOk"),  Bank of Texas, N.A., Bank of Albuquerque,  N.A., and Bank of Arkansas,
N.A.  Other  significant  operating  subsidiaries  include BOK Capital  Services
Corporation  which provides  leasing and mezzanine  financing and BOSC,  Inc., a
broker/dealer  and "Section 20" company that engages in retail and institutional
securities  sales and municipal  underwriting.  Our  discussion of Bank of Texas
includes  Canyon Creek  National  Bank,  Swiss Avenue State Bank and  Mid-Cities
National Bank.  These banks were acquired  during 1999 and were accounted for by
the purchase method of accounting. These banks will be merged into Bank of Texas
during 2000.


Assessment of Operations

SUMMARY OF PERFORMANCE

     BOK  Financial  recorded net income of $89.2  million for 1999  compared to
$79.6  million for 1998.  Diluted  earnings per common share were $1.60 for 1999
compared to $1.43 for 1998.  Prior year's  results have been restated to reflect
the merger with First Muskogee  Bancshares,  Inc.  during 1999.  This merger was
accounted for as a pooling of  interests.  Prior period per share data have been
restated  to reflect a 3% stock  dividend  paid in the  fourth  quarter of 1999.
Returns  on  average   assets  and   average   equity  were  1.17%  and  16.45%,
respectively, for 1999 compared to 1.34% and 16.38%, respectively, for 1998.
     The increase in net income for 1999 was due to  increases of $45.7  million
or 24% in net interest revenue, $19.2 million or 12% in fees and commissions and
a $4.2 million reduction in the provision for loan losses.  These increases were
partially offset by increases of $46.5 million or 20% in operating  expenses and
$7.2  million  in income  taxes and a $5.8  million  decrease  in gains on asset
sales.
     Net income for the  fourth  quarter of 1999 was $23.2  million or $0.42 per
diluted  common  share,  an increase  of 14% over the same  period on 1998.  The
primary sources of increased  quarterly  earnings included net interest revenue,
which increased $14.0 million or 27%, and fees and commissions,  which increased
$4.1 million or 10%. These  increases  were partially  offset by a $12.0 million
increase in operating expenses.
     Net income for 1997 was $68.2  million or $1.23 per diluted  common  share.
Returns on average assets and equity were 1.29% and 16.78%, respectively.


TANGIBLE OPERATING RESULTS

     Since inception, BOK Financial has completed several acquisitions that were
accounted  for under the purchase  method of  accounting.  The  purchase  method
results in the recording of goodwill and other  identifiable  intangible  assets
that are amortized as noncash  charges in future years into  operating  expense.
The  intangible  assets that result from the purchase  method of accounting  are
deducted from shareholders'  equity in the determination of regulatory  capital.
Thus,  tangible  net  income,  net  income  excluding  the  after-tax  effect of
intangible  amortization,  represents  regulatory  capital  generated during the
year.  While the  definition  of  tangible  net income may vary by  company,  we
believe this  definition is  appropriate  as it measures the per share growth of
regulatory  capital,  which  affects the amounts  available  for  dividends  and
acquisitions.  Operating results excluding the impact of these intangible assets
are summarized below:

NET INTEREST REVENUE

     Net interest revenue, on a tax-equivalent basis, totaled $244.5 million for
1999 compared to $199.9 million for 1998.  The increase in net interest  revenue
was  primarily due to an increase in average  earning  assets.  Average  earning
assets  increased by $1.4 billion  during  1999,  including  $626 million due to
acquisitions   and  $821   million  due  to  growth  in   existing   businesses.
Additionally,  the mix of earning assets  improved  during 1999.  Average loans,
which generally have higher yields than other types of earning assets, increased
to 60% of earning  assets in 1999 compared to 56% in 1998.  These volume factors
contributed  $111.7  million to the  increase in net interest  revenue.
     Average interest bearing  liabilities also increased by $1.5 billion during
1999,  including $811 million from borrowed funds and $490 million from deposits
at  acquired  banks.  The  increase  in  average  interest  bearing  liabilities
decreased net interest revenue by $69.4 million.

     Net interest  margin,  the ratio of net interest revenue to average earning
assets,  decreased  from 3.72% in 1998 to 3.63% in 1999.  This  decrease was due
primarily  to the  effect of  competitive  pricing  on loans in BOK  Financial's
primary markets.  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 to invest in securities.  Although this
strategy  frequently  results in a net  interest  margin  that falls below those
normally  seen in the  commercial  banking  industry,  it provides  positive net
interest revenue.  Management estimates that for 1999, this strategy resulted in
a 59 basis  point  decrease  in net  interest  margin.  However,  this  strategy
contributed  $13.2  million to net interest  revenue for the year. As more fully
discussed in the  subsequent  Market Risk Section,  management  employs  various
techniques  to control,  within  established  parameters,  the interest rate and
liquidity risk inherent in this strategy.
     The financial  service  environment in BOK  Financial's  primary markets is
highly  competitive due to a large number of commercial banks,  thrifts,  credit
unions and brokerage firms.  Additionally,  many customers already had access to
national and regional  financial  institutions  for many  products and services.
Management  expects that BOK Financial will continue to be able to  successfully
compete  with these  financial  institutions  by  delivering  the  products  and
services traditionally associated with a large bank with the responsiveness of a
smaller, community bank.
     Tax-equivalent  net  interest  revenue  for the fourth  quarter of 1999 was
$67.0  million  compared to $53.4 million for the fourth  quarter of 1998.  This
increase was due to the growth in average earning  assets,  which increased $1.5
billion or 26%. Net interest margin decreased 2 basis points to 3.70%.
     Net interest revenue, on a tax-equivalent basis, totaled $199.9 million for
1998 compared to $171.9 million in 1997.  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 7.85% in 1997 to 7.75% in 1998 as
both securities and loans showed yield decreases.  At the same time, the cost of
interest-bearing  liabilities  decreased  from 4.87% to 4.77%.  Average  earning
assets  increased $610 million,  including  $392 million  increase from net loan
fundings, and $228 million from net securities purchases.  Over the same period,
average  interest-bearing  liabilities increased $448 million,  including a $307
million  increase in deposit  accounts that generally have a lower cost of funds
rate.

    Other operating revenue increased $13.4 million or 8% compared to 1998. Fees
and commissions,  which are included in other operating revenue, increased $19.2
million or 12% while net gains on sales of securities and other assets decreased
$5.8 million. The increase in fees and commissions included deposit fees of $4.9
million,  transaction  card fees of $1.5 million and other fees of $599 thousand
from acquired banks. Fees and commissions  excluding the acquired fees increased
7%. Fees and commissions  contributed  43% of BOK Financial's  total revenue for
1999  compared  to 45% in 1998.  The  decrease in the  contribution  of fees and
commissions  to total  revenue  was due to the large  increase  in net  interest
revenue relative to the growth in fees and commissions and decreases in mortgage
banking  revenue and leasing  revenue.  Service fees on deposits  totaled  $41.1
million,  an  increase  of  21%  over  1998.  Revenue  generated  by  card-based
transactions such as the TransFund ATM network,  bankcards, and related merchant
deposits increased by 34% to $32.6 million. These increases are generally due to
a higher volume of transactions  processed in 1999.  Other revenue included $5.2
million of private  placement and underwriting fees related to BOSC's activities
in 1999 compared to $819 thousand in 1998.  During 1999,  BOK Financial sold its
interest in four leasing  partnerships for a gain of $3.6 million which caused a
decrease in leasing  revenue for the year.  The decrease in leasing  revenue was
substantially  offset by a  reduction  in  depreciation  expense  on the  leased
equipment and the opportunity to reinvest the $29 million sales proceeds.
<PAGE> 13

     Many of BOK  Financial's fee generating  activities,  such as brokerage and
trading activities,  trust fees, and mortgage servicing revenue,  are indirectly
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 related  revenue.
     While management expects continued growth in other operating  revenue,  the
future rate of increase could be affected by increased competition from national
and regional financial institutions and from market saturation. Continued growth
may require BOK  Financial  to  introduce  new products or to enter new markets.
This growth introduces  additional demands on capital and managerial  resources.
     Other  operating  revenue  for the  fourth  quarter of 1999  totaled  $46.7
million  compared to $45.4  million for the fourth  quarter of 1998.  The fourth
quarter  of 1998  included  securities  gains of $3.0  million  compared  to $80
thousand  in the fourth  quarter of 1999.  Changes  in the  components  of other
revenue during the fourth quarter were consistent with the year to date changes.
Transaction  card revenue and deposit service fees increased by $2.4 million and
$1.1 million,  respectively,  while mortgage  banking revenue  decreased by $1.9
million.  Leasing  revenue  decrease  by  $1.4  million  due to the  sale of BOK
Financial's  interests in several leasing partnerships during the second quarter
of 1999.
     Other operating revenue for 1998 increased $43.5 million or 33% compared to
1997.  Approximately $10.7 million of this increase was due to the net change in
gains on  securities  sold.  All areas  contributed  to this  increase  in other
revenue,  including mortgage banking revenue which increased $9.5 million, trust
fees which  increased  $5.9  million and  brokerage  and trading  revenue  which
increased $5.7 million.


LINES OF BUSINESS

     BOK Financial  operates four principal  lines of business under its Bank of
Oklahoma franchise:  corporate banking,  consumer banking,  mortgage banking and
trust services.  It also operates a fifth  principal line of business,  regional
banks,  which  includes  banking  functions  for  Bank of  Albuquerque,  Bank of
Arkansas  and Bank of Texas.  These five  principal  lines of business  combined
account for approximately 86% of total revenue.  Other lines of business include
the TransFund ATM system and BOSC, Inc.

Corporate Banking

     The  Corporate  Banking  Division  provides  loan and lease  financing  and
treasury and cash  management  services to  businesses  throughout  Oklahoma and
seven  surrounding  states.  In addition to serving the banking  needs of middle
market and larger  customers,  the Corporate  Banking  Division has  specialized
groups  which  serve  customers  in  the  energy,  agriculture,  healthcare  and
banking/finance  industries.  The Corporate Banking Division  contributed 53% of
consolidated  net income for 1999 compared to 48% of consolidated net income for
1998.  Total  revenue for this  division  increased  16%  primarily due to a 26%
increase in outstanding loans. Operating expense for this division increased 7%.

Consumer Banking

     The Consumer Banking Division  provides its customers  throughout  Oklahoma
with a full line of deposit,  loan and  fee-based  services  through  four major
distribution channels:  traditional branches,  supermarket branches, the 24-hour
ExpressBank  call  center,  and the  Internet.  Additionally,  the division is a
significant  referral  source for the Bank of Oklahoma  Mortgage  Division ("BOk
Mortgage") and BOSC's Retail Brokerage  division.  The Consumer Banking Division
contributed 12% of consolidated  net income for 1999 and 11% of consolidated net
income for 1998. Total revenue,  which consists primarily of intercompany credit
for funds provided to other divisions within BOK Financial and fees generated by
various  services,  increased 4% during 1999.  Operating  expenses for this same
period  decreased  slightly during 1999. The result is an improvement in returns
on average assets and equity for the division and a lower efficiency ratio.

Mortgage Banking

     BOK Financial engages in mortgage banking  activities through BOk Mortgage.
These activities  include the  origination,  marketing and servicing of mortgage
loans.  BOk Mortgage  contributed 2% to consolidated net income in 1999 compared
to 8% in 1998.
     Total revenue from BOk Mortgage  decreased $7.2 million or 14% during 1999.
Revenue provided by origination and marketing  activities in 1999 decreased $4.7
million or 57% compared to 1998. Total mortgage loan production was $688 million
for 1999 compared to $923 million in 1998.  The decrease in loan  production was
due to rising interest rates in 1999.
     Commitments  to  originate  mortgage  loans create both credit and interest
rate risk. Credit risk is managed through underwriting  policies and procedures,
and interest rate risk is partially hedged through forward sales contracts.  All
fixed rate mortgage loans are generally sold in the secondary market pursuant to
forward sales  contracts.  All  adjustable  rate  mortgage  loans are sold to an
affiliate.  BOk Mortgage  currently does not securitize  pools of mortgage loans
either for sale or retention.
     Mortgage loan servicing  revenue totaled $33.4 million for 1999 compared to
$33.5 million for 1998.  Mortgage  loans  serviced by BOk Mortgage  totaled $7.0
billion at December 31, 1999 compared to $6.4 billion at the end of 1998.  These
amounts include loans serviced for BOk of $107 million for 1999 and $130 million
for 1998.
     Capitalized  mortgage  servicing  rights,  which totaled  $114.1 million at
December  31, 1999 and $69.2  million at December  31, 1998  represent  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 are 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  servicing  rights while falling
interest rates have the opposite effect.  A valuation  allowance is provided for
the excess of the carrying value of servicing rights over their fair values.  In
1998,  BOk Mortgage  implemented a program that uses futures  contracts and call
and put options to hedge  against  this risk.  Gains  generated  by this program
reduce the cost basis of the mortgage  servicing rights while losses incurred by
this program  increase the cost basis of the servicing  rights.  At December 31,
1999,  cumulative hedging losses increased the cost of mortgage servicing rights
by $10.4  million.  At December 31,  1998,  cumulative  gains  generated by this
program  increased  the cost  basis of the  mortgage  servicing  rights by $22.5
million.  Additional  discussion about the sensitivity of the mortgage servicing
portfolio to changes in interest rates is in the Market Risk section.

Trust Services

     BOK  Financial   provides  a  wide  range  of  trust  services,   including
institutional,  investment  and  retirement  products  and  services to affluent
individuals and businesses,  to  not-for-profit  organizations  and governmental
agencies  through the Bank of Oklahoma  Trust  Division  and Bank of Texas Trust
Company.  Trust services are primarily  provided to clients in Oklahoma,  Texas,
Arkansas  and New Mexico.  Additionally,  trust  services  include a  nationally
competitive  self-directed  401-K program with clients in Dallas,  Chicago,  New
York and Los  Angeles.  At December  31,  1999,  trust  assets with an aggregate
market value of $17.2  billion were subject to various  fiduciary  arrangements,
compared to $14.4 billion at December 31, 1998.  Trust services  contributed 10%
to consolidated  net income for 1999 compared to 8% for 1998. Total revenue from
trust  services  increased  $8.6  million  or 19% during  1999  while  operating
expenses increased $3.8 million.

Regional Banks

     Regional  banks  include  Bank of  Texas,  Bank of  Arkansas,  and  Bank of
Albuquerque. Each of these banks provides a full range of corporate and consumer
banking,  trust  services,  treasury  services and retail  investments  in their
respective  markets.  Small  businesses and  middle-market  corporations are the
regional  banks' primary  customer  focus.  During 1999, BOK Financial  acquired
Canyon Creek  National  Bank,  Mid Cities  National  Bank and Swiss Avenue State
Bank.  These  acquisitions  added  assets of $430  million and  deposits of $354
million  to Bank of Texas.
     Regional banks contributed $7.7 million or 9% to consolidated net income in
1999 compared to $5.7 million or 7% in 1998.  Total  revenue for 1999  increased
$38.9 million compared to 1998 while operating expenses increased $35.3 million.
The  increase  in  operating  expenses  included  a  $6.1  million  increase  in
intangible  amortization expense.  Average equity assigned to the regional banks
included  both an  amount  based  on  management's  assessment  of  risk  and an
additional amount based upon BOK Financial's investment in these entities.

YEAR 2000 CONSIDERATIONS


     The Year 2000 issue, in general,  is the result of computer  programs being
written using two digits  rather than four to define the  applicable  year.  Any
computer  programs that have date sensitive  software may recognize a date using
"00" as the year 1900 rather than the year 2000.  This could  result in a system
failure or miscalculations  causing  disruptions of operations,  including among
other  things,  a temporary  inability to process  transactions  or to engage in
similar normal business activities.
     BOK Financial personnel continue to monitor its information  technology and
non-information  technology  systems and to communicate  with large customers to
determine  whether  any  disruptions  have  occurred.  To date,  no  significant
disruptions in operations have been identified.  Total accumulated  expenditures
directly  related to the Year 2000  issue were less than $1 million  and no more
are expected.


OTHER OPERATING EXPENSE

     Other operating  expense totaled $280.5 million for 1999 compared to $234.0
million  in 1998,  an  increase  of 20%.  Approximately  $30.2  million  of this
increase  was  related to  acquisitions.  Operating  expenses  for  acquisitions
increased  personnel  costs  by $11.5  million,  occupancy,  equipment  and data
processing  expenses by $5.5 million,  and amortization of intangible  assets by
$6.8 million.  Excluding the effects of  acquisitions,  other operating  expense
increased  $16.3 million or 7%.
     Personnel costs increased $26.6 million or 24%.  Regular  compensation  and
benefits (including overtime and temporary  assistance)  increased $18.0 million
or 22%.  Staffing  on a full time  equivalent  ("FTE")  basis  increased  by 333
employees or 13% while average compensation expense per FTE increased by 9%. The
transition  toward  performance  based   compensation   continued  during  1999.
Incentive  compensation increased by $5.4 million or 46% compared to 1998 due to
growth in  revenue  over  pre-determined  targets  and  growth in the  number of
business units covered by incentive  plans.
     Net  occupancy,  equipment and data  processing  expense for 1999 increased
$14.5 million or 33%. Net occupancy expense increased by $4.4 million, including
$2.5 million due to acquisitions.  The remaining  increase was due to additional
locations in Oklahoma and Texas. Data processing expenses increased $5.9 million
or 28%, including $1.2 million from  acquisitions.  Amortization and maintenance
costs  increased  $1.3  million  during 1999 to $3.3  million due  primarily  to
various systems  implemented over the past two years. The remaining increase was
due to a higher volume of transactions  processed.
     Other  operating  expenses  for the fourth  quarter of 1999  totaled  $74.3
million  compared to $62.3  million for the fourth  quarter of 1998.  The fourth
quarter of 1999 included expenses of $9.4 million related to recent acquisitions
and the fourth quarter of 1998 included the reversal of the valuation  allowance
for mortgage  servicing  rights of $4.3 million.  Excluding the effects of these
items,  operating  expenses for the quarters were essentially  unchanged.
     Other operating  expense totaled $234.0 million for 1998 compared to $199.9
million in 1997, an increase of 17%. Personnel costs increased $18.8 million due
primarily to an 11% increase in the number of full time equivalent  staffing and
a 6% increase in average compensation per employee. Net occupancy, equipment and
data processing  expenses  increased $7.3 million.  Occupancy costs increased by
$2.5  million due to lower  rental  income of $1.2  million  and a $1.3  million
increase in expenses.  The lower rental  income was related to a change in BOk's
ownership interest in its Oklahoma City headquarters building while the increase
in occupancy  expenses was due to an increase in rent for BOk.  Data  processing
expenses  increased $4.1 million or 24% due to a greater volume of  transactions
processed.  Additionally,  data  processing  expenses  for  1998  included  $350
thousand for Bank of Albuquerque system conversions and related start up costs.

Income Taxes

     Income tax expense was $44.5 million,  $37.2 million, and $16.5 million for
1999,   1998,  and  1997,   respectively,   representing   33%,  32%,  and  20%,
respectively,  of book taxable  income.  Tax expense  currently  payable totaled
$43.8  million in 1999  compared to $46.4  million in 1998 and $11.0  million in
1997. The Internal  Revenue  Service  closed its  examination of 1996 during the
first quarter of 2000.  This  examination had no adverse impact on the financial
statements  and BOK  Financial  is  evaluating  the  impact,  if any, on its tax
reserve.  During 1998,  Internal Revenue Service  examinations for 1994 and 1995
were closed with no significant  adjustments.  During 1997, the Internal Revenue
Service  closed  its  examination  of BOk and BOK  Financial  for 1992 and 1993,
respectively.  As a result of the outcome of these  examinations,  BOK Financial
reduced its tax reserve by $9.0 million.  Income tax expense for 1997 was 30% of
pre-tax book income excluding the elimination of this allowance.

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  that  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 on available for sale  securities,  less
applicable  deferred  taxes,  are recorded as  accumulated  other  comprehensive
income in Shareholders' Equity.
     During 1999,  BOK  Financial  increased  its  securities  portfolio by $335
million.  Most  notably,  mortgage-backed  securities  increased by $460 million
while municipal securities decreased by $78 million.
     BOK Financial's total securities portfolio value changed from an unrealized
gain of $19 million at December 31, 1998 to an unrealized loss of $73 million at
December 31, 1999 due to an increase in market  interest  rates during the year.
Rising  interest rates tend to both decrease the value of fixed rate  securities
and extend the average expected life of mortgage-backed securities.
     The average expected life of the  mortgage-backed  securities was 4.4 years
at December 31, 1999  compared to 4.0 years at December 31, 1998.  The effect of
changes in interest rates on BOK Financial's earnings and equity is discussed in
the Market Risk section of this report.
     Table 12  presents  the book  values  and fair  values  of BOK  Financial's
securities portfolio at December 31, 1999, 1998 and 1997. Additional information
regarding the  securities  portfolio is presented in Note 4 to the  Consolidated
Financial Statements.

LOANS

     Loans  increased  $996 million or 27% during 1999,  including  $148 million
from acquisitions.  Excluding acquisitions, loans increased $848 million or 23%.
Commercial  loans  increased by $675 million or 34% over 1998.  This continues a
trend of strong growth in  commercial  loans.  All segments of commercial  loans
grew by more than 10% except  agriculture.  Commercial loans now comprise 57% of
total loans compared to 55% at December 31, 1998. Energy loans increased by $138
million or 29% during 1999 and totaled $607 million or 13% of the loan portfolio
at year-end.  Commercial loans to service entities  increased by $172 million or
27% during 1999.  Total commercial real estate loans grew by $334 million or 44%
during 1999.  Multifamily  loans and construction  and land  development  loans,
which consists primarily of single family construction  loans,  increased by 42%
and 43%,  respectively,  during 1999.  Management  plans to decrease the rate of
loan growth in 2000  through a selective  tightening  of credit  standards.  The
primary focus will be on commercial  lending activities that have an opportunity
to provide other banking  services to the customer.
     During 1999, BOK Financial  securitized and sold approximately $100 million
of  automobile  loans for net cash  proceeds  of $94.5  million.  BOK  Financial
retained the servicing rights  associated with the loans and a residual interest
in cash flows in excess of set targets. At December 31, 1999, the carrying value
of the servicing rights was $343 thousand and the carrying value of the residual
interest was $9.8 million.  These carrying values are based on the present value
of future net cash that BOK Financial expects to receive. Additional information
regarding  the  automobile  loan  securitization  is  presented in Note 5 to the
Consolidated Financial Statements.

Approximately  53% of  commercial  real  estate  loans are  secured by  property
located in Oklahoma, primarily in the Tulsa or Oklahoma City metropolitan areas.
An  additional  12% of  commercial  real  estate  loans are  secured by property
located in Texas.  The major  components  of other real estate  loans are office

SUMMARY OF LOAN LOSS EXPERIENCE

         The reserve  for loans  losses,  which is  available  to absorb  losses
inherent  in the loan  portfolio,  totaled $76  million at  December  31,  1999,
compared to $66 million at December 31, 1998. This represents 1.66% and 1.86% of
total  loans,  excluding  loans held for sale,  at  December  31, 1999 and 1998,
respectively.  Losses  on  loans  held  for  sale,  principally  mortgage  loans
accumulated for placement in securitized  pools, are charged to earnings through
adjustments in carrying value to the lower of cost or market value in accordance
with  accounting  standards  applicable to mortgage  banking.  Table 15 presents
statistical  information regarding the reserve for loan losses for the past five
years.

</TABLE>

     The adequacy of the reserve for loan losses is assessed by management based
upon an ongoing quarterly  evaluation of the probable  estimated losses inherent
in the portfolio,  and includes  probable losses on both  outstanding  loans and
unused  commitments  to provide  financing.  A consistent  methodology  has been
developed that includes reserves assigned to specific criticized loans,  general
reserves that are based upon a statistical  migration analysis for each category
of loans,  and  unallocated  reserves that are based upon an analysis of current
economic conditions,  loan concentrations,  portfolio growth, and other relevant
factors.  An independent  Credit  Administration  department is responsible  for
performing  this  evaluation for all of BOK  Financial's  subsidiaries to ensure
that the methodology is applied consistently.
     All  significant  criticized  loans are  reviewed  quarterly  with  written
documentation.  Specific  reserves for  impairment  are determined in accordance
with  generally  accepted  accounting  principles  and  appropriate   regulatory
standards.  At December  31, 1999  specific  impairment  reserves  totaled  $2.5
million.
     The adequacy of general loan loss reserves is determined  primarily through
an  internally   developed   migration   analysis  model.   Management  uses  an
eight-quarter  aggregate  accumulation  of net loan losses as the basis for this
model. Greater emphasis is placed on net loan losses in the more recent periods.
This model is used to assign general loan loss reserves to commercial  loans and
leases,  residential  mortgage loans and consumer loans.  All loans,  leases and
letters of credit are allocated a migration factor by this model. Management can
override the general allocation only by utilizing a specific  allocation that is
greater  than the general  allocation.  General loan loss  reserves  assigned to
various categories of loans are presented in Table 16.
     A  nonspecific  allowance  for loan losses is  maintained  for risks beyond
those factors specific to a particular loan or those identified by the migration
analysis.  These factors  include trends in general  economic  conditions in BOK
Financial's  primary  lending areas,  duration of the business  cycle,  specific
conditions in  industries  where BOK  Financial  has a  concentration  of loans,
overall growth in the loan portfolio, bank regulatory examination results, error
potential in either the migration  analysis model or in the underlying data, and
other relevant factors.  A range of potential losses is then determined for each
factor identified.
<PAGE> 21

       At December 31, 1999, the loss potential  ranges for the more significant
factors are:

    Concentration of large loans - $1.1 million to $2.1 million
    Loan portfolio growth and expansion into new markets - $1.3 million to $2.6
      million


     A  provision  for loan  losses  is  charged  against  earnings  in  amounts
necessary to maintain an adequate  allowance for loan losses.  These  provisions
totaled  $10.4  million for 1999,  $14.6  million for 1998 and $9.3  million for
1997. The provision for 1999 reflected management's assessment of changes in the
risk of loan losses due primarily to continued  growth in the loan portfolio and
geographic  expansion of BOK Financial's  market area to include North Texas and
New Mexico.

NONPERFORMING ASSETS

     Information  regarding  nonperforming  assets,  which  were $23  million at
December 31, 1999 and $19 million at December 31, 1998 is presented in Table 17.
Nonperforming loans include nonaccrual loans and renegotiated loans and excludes
loans 90 days or more past due.  Nonaccrual  commercial  loans increased  during
1999 due primarily to an identified  weakness in one agriculture  loan.
     The loan review process also  identifies  loans 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,  1999,  loans  totaling  $67  million  were  assigned  to  the
substandard  risk  category and loans  totaling $29 million were assigned to the
special  mention  risk  category,  compared  to $60  million  and  $31  million,
respectively, at December 31, 1998.

DEPOSITS

     Average  deposits  for  1999  increased  $771  million  compared  to  1998,
including  $596 million from  acquisitions.  Demand  deposits,  interest-bearing
transaction  accounts and time deposits  increased by $65 million,  $501 million
and $196  million,  respectively.  The average cost of each category of interest
bearing deposits has decreased during 1999 due to lower market interest rates.
     As shown in Table 18, average core deposits  increased $487 million to $3.2
billion.  This  represented  65% of  average  deposits  in both  1999 and  1998.
Concurrently,  uninsured  deposits  increased to 27% of total  deposits for 1999
compared to 24% in 1998. Average uninsured deposits included  approximately $257
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 styling that would determine insurance based on FDIC
regulations.

     BOK  Financial  competes for deposits by offering a broad range of products
and services to its customers. While this includes offering competitive interest
rates and fees, the primary means of competing for deposits is  convenience  and
service to the customers. BOk offers banking convenience to its customers though
69 branches, including 26 branches with extended hours in local supermarkets and
a 24-hour  ExpressBank  call center.  During 1999,  BOk opened four  supermarket
branches to further enhance customer convenience. Acquisitions during 1999 added
6 locations  to Bank of Texas which  brought its total  locations to 13. Bank of
Albuquerque  has 15 banking  locations  in  Albuquerque,  New Mexico and Bank of
Arkansas has 3 locations in Fayetteville, Arkansas.

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

BORROWINGS AND CAPITAL

     BOK Financial and its  subsidiary  banks use several  borrowing  sources to
supplement  deposits as a source of funds to support loan and securities growth.
Primarily   these  sources   include  federal  funds  purchased  and  securities
repurchase agreements,  advances from the Federal Home Loan Bank, and borrowings
from lines of credit through commercial banks.  Average borrowed funds increased
$811 million or 71% over 1998 and represented 28% of all funds for 1999 compared
to 22% for 1998.  Interest rates and maturity  dates for the various  sources of
funds  are  matched  with  specific  types  of  assets  in  the  asset/liability
management process.
     In February  1999,  the Board of Directors  increased  the number of shares
which  management is authorized  to  repurchase  an additional  400,000  shares,
increasing   total   authorization   to  800,000  shares.   Since  the  original
authorization announced in 1998, the Company has repurchased 466,540 shares.
     During the fourth quarter of 1999, BOK Financial  negotiated a $125 million
variable  rate,  unsecured  line of  credit.  The  proceeds  of this  line  were
primarily used to pay off bank debt that had been incurred to fund acquisitions.
Interest  on  amounts  outstanding  under this line is based on either the LIBOR
rate or a base rate,  plus a defined margin which is determined by the amount of
principal  outstanding and BOK Financial's debt rating. The base rate is defined
as the greater of either the daily federal funds rate or the prime rate.
     Equity capital for BOK Financial averaged $542 million and $486 million for
1999 and  1998,  respectively.  The $56  million  increase  resulted  from  1999
earnings and a $24 million  decrease in  unrealized  gains on available for sale
securities.  See Note 15 to the Consolidated Financial Statements for additional
information  regarding the capital  adequacy of BOK Financial and its subsidiary
banks.
     Management has identified capital and funding needs totaling  approximately
$50 million for anticipated  growth in 2000.  Resources  available to meet these
needs include  dividends from BOK Financial's  subsidiary banks and the possible
issuance of debt.  Management  currently  believes that its funding needs can be
met by dividends from its subsidiary  banks.  However,  the timing and extent of
future growth plans will be evaluated based upon available resources.

MARKET RISK

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

Interest Rate Risk Management (Other than Trading)

           BOK  Financial  performs a  sensitivity  analysis  to  identify  more
dynamic interest rate risk exposures, including embedded option positions on net
interest revenue, net income and economic value of equity. A simulation model is
used to estimate  the effect of changes in  interest  rates over the next twelve
months based on three  interest rate  scenarios.  These are a "most likely" rate
scenario and two "shock test" scenarios, the first assuming a sustained parallel
200 basis point  increase  and the second a sustained  parallel  200 basis point
decrease in interest rates. An independent  source is used to determine the most
likely  interest  rates for the next year. The Federal  Reserve Bank's  discount
rate  affects  short-term  borrowings,  the prime  lending  rate and the  London
InterBank Offering Rate ("LIBOR"). These rates in turn are the basis for much of
the  variable-rate  loan  pricing,  the 30-year  mortgage  rate (which  directly
affects  the  prepayment  speeds for  mortgage-backed  securities  and  mortgage
servicing  rights),  and the 10-year U.S. Treasury rate (which affects the value
of the mortgage servicing hedges) and,  therefore,  are BOK Financial's  primary
interest rate exposures.  Derivative  financial  instruments and other financial
instruments   used  for  purposes  other  than  trading  are  included  in  this
simulation.  In  addition,  sensitivity  of fee income to market  interest  rate
levels,  such  as  those  related  to  cash  management  services  and  mortgage
servicing,  are included. The model incorporates assumptions regarding the level
of interest rate or balance changes on indeterminable  maturity deposits (demand
deposits,  interest-bearing  transaction  accounts and savings  accounts)  for a
given level of market rate changes.  The assumptions have been developed through
a  combination  of historical  analysis and future  expected  pricing  behavior.
Interest  rate swaps on all  products  are  included to the extent that they are
effective in the 12-month  simulation period.  Changes in prepayment behavior of
mortgage-backed securities, residential mortgage loans and mortgage servicing in
each rate environment are captured using industry estimates of prepayment speeds
for various coupon  segments of the portfolio.  The impact of planned growth and
new business  activities is factored into the simulation  model. At December 31,
1999 and 1998, this modeling indicated interest rate sensitivity as follows:

     The  estimated  changes in  interest  rates on net  interest  revenue,  net
income,  and economic  value of equity is within  guidelines  established by the
Board  of  Directors  for all  interest  rate  scenarios.
     BOK Financial has a significant  risk of loss on its  capitalized  mortgage
servicing  rights in a declining  interest  rate  environment.  During  1998,  a
program to hedge  this  exposure  through  the use of  futures  contracts,  call
options and put options was developed.  These derivatives are based upon 10-year
U.S.  Treasury  securities.  The  changes in value of these  derivatives  have a
highly  correlated,  inverse  relation  to  changes  in  value  of the  mortgage
servicing  rights within a +/- 50 basis point range.  During 1999,  the interest
rates that affect the value of the servicing rights and the hedging  derivatives
increased by 179 basis points. This large change in rates caused the derivatives
to generate losses of $32.2 million while the value of the hedged portion of the
servicing portfolio increased by $25.9 million. Cumulative losses on the hedging
portfolio  at  December  31, 1999 were $8.9  million  before  amortization.  The
interest rate  sensitivity of the mortgage  servicing  portfolio and the related
hedge is modeled  over a range of + or - 50 basis  points.  At December 31, 1999
and 1998, the pre-tax results of this modeling are as follows:

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

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

<PAGE> 24

    BOK  Financial  uses  interest  rate  swaps,  a form  of  off-balance  sheet
derivative  product,  in managing its interest rate sensitivity.  These products
are  generally  used to more closely match  interest  paid on certain  long-term
certificates of deposit and subordinated debt with earning assets.  During 1999,
income from these swaps  exceeded the cost 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.

Trading Activities

     BOK  Financial   enters  into  trading   account   activities  both  as  an
intermediary  for customers  and for its own account.  As an  intermediary,  BOK
Financial  will  take  positions  in   securities,   generally   mortgage-backed
securities,  government agency securities, and municipal bonds. These securities
are purchased for resale to customers, which include individuals,  corporations,
foundations,  and financial  institutions.  BOK Financial will also take trading
positions in U.S. Treasury  securities,  mortgage-backed  securities,  municipal
securities,  and  financial  futures for its own account  either  through BOk or
BOSC,  Inc. These  positions are taken with the objective of generating  trading
profits. Both of these activities involve interest rate risk.
         A variety  of  methods  are used to manage  the  interest  rate risk of
trading  activities.  These  methods  include  daily marking of all positions to
market value, independent verification of inventory pricing, and position limits
for each trading  activity.  Hedges in either the futures or cash markets may be
used to  reduce  the  risk  associated  with  some  trading  programs.  The Risk
Management  Department  monitors  trading  activity  daily and reports to senior
management and the Risk Oversight and Audit Committee of the BOK Financial Board
of Directors  any  exceptions  to trading  position  limits and risk  management
policy exceptions.
     BOK  Financial  uses a Value at Risk  ("VAR")  methodology  to measure  the
market risk inherent in its trading  activities.  VAR is  calculated  based upon
historical  simulations  over the past five years.  It  represents  an amount of
market  loss that is likely to be  exceeded  only one out of every 100  two-week
periods.  Trading positions are managed within guidelines  approved by the Board
of Directors.  These guidelines limit the nominal aggregate trading positions to
$360  million,  the VAR to $6.5  million.  At  December  31,  1999,  the nominal
aggregate  trading  positions was $4.9 million,  the VAR was $149 thousand.  The
greatest value at risk during 1999 was $2.1 million.


NEW ACCOUNTING STANDARDS

     During 1998, the Financial Accounting Standards Board adopted Statement No.
133, "Accounting for Derivative Instruments and Hedging Activities" ("FAS 133").
The effective  date for FAS 133 has been deferred  until fiscal years  beginning
after June 15, 2000. BOK Financial expects to adopt FAS 133 effective January 1,
2001.  FAS 133 will require the  recognition  of all  derivatives on the balance
sheet  at  fair  value.  Derivatives  that  do not  qualify  for  special  hedge
accounting  treatment  must be adjusted  to fair value  through  income.  If the
derivative qualifies for hedge accounting, depending on the nature of the hedge,
changes  in the fair  value of the  derivatives  will  either be offset  against
changes in fair value of the hedged  assets,  liabilities,  or firm  commitments
through  earnings or recognized in other  comprehensive  income until the hedged
item is recognized in earnings. The ineffective portion of a derivative's change
in fair value will be immediately recognized in earnings.
     BOK  Financial  is  currently  analyzing  the  effect  of  FAS  133  on the
derivatives used as part of its asset/liability  management program.  The effect
of FAS 133 on earnings and financial position has not yet been determined.

FORWARD-LOOKING STATEMENTS

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

REPORT OF MANAGEMENT ON FINANCIAL STATEMENTS

     Management is responsible for the consolidated  financial  statements which
have been prepared in accordance with 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  accounting  principles
generally  accepted in the United States.  This system includes written policies
and  procedures,  a corporate  code of conduct,  an internal  audit  program and
standards for the hiring and training of qualified personnel.

     The Board of  Directors of BOK  Financial  maintains a Risk  Oversight  and
Audit  Committee  consisting of outside  directors that meet  periodically  with
management and BOK Financial's internal and independent auditors.  The Committee
considers  the audit and nonaudit  services to be  performed by the  independent
auditors,  makes  arrangements  for the  internal  and  independent  audits  and
recommends BOK Financial's selection of independent auditors. The Committee also
reviews  the results of the  internal  and  independent  audits,  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  accounting  principles  generally
accepted in the United States and their report on BOK  Financial's  consolidated
financial statements is set forth below.


REPORT OF INDEPENDENT AUDITORS

     We  have  audited  the  accompanying  consolidated  balance  sheets  of BOK
Financial  Corporation  as of  December  31,  1999  and  1998,  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, 1999.  These
financial  statements are the  responsibility of the Company's  management.  Our
responsibility  is to express an opinion on these financial  statements based on
our audits.

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

     In our opinion,  the consolidated  financial  statements  referred to above
present fairly, in all material respects, the consolidated financial position of
BOK Financial  Corporation at December 31, 1999 and 1998,  and the  consolidated
results of its  operations and its cash flows for each of the three years in the
period  ended  December 31,  1999,  in  conformity  with  accounting  principles
generally accepted in the United States.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) SIGNIFICANT ACCOUNTING POLICIES


Basis of Presentation

     The Consolidated  Financial  Statements of BOK Financial  Corporation ("BOK
Financial")  have  been  prepared  in  conformity  with  accounting   principles
generally  accepted in the United  States,  including  general  practices of the
banking industry.  The consolidated financial statements include the accounts of
BOK Financial and its subsidiaries,  principally Bank of Oklahoma,  N.A. and its
subsidiaries ("BOk"),  Bank of Texas, N.A., Bank of Arkansas,  N.A., and Bank of
Albuquerque,  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, North Texas and Northern
New Mexico.  These services include depository and cash management;  lending and
lease  financing;   mortgage   banking;   securities   brokerage,   trading  and
underwriting; and personal and corporate trust.

Use of Estimates

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

Acquisitions

     Assets and liabilities  acquired by purchase are recorded at fair values on
the acquisition dates.  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.  These conditions would include an
ongoing  performance  history and a forecast of anticipated  performance that is
significantly below management's expectations for acquired entities.  Impairment
would be determined by a comparison of the fair value of assets and  liabilities
of the  acquired  entity plus an estimate of current  market  premiums  paid for
similar entities. 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.  Unrealized  gains and losses are  recorded,
net of deferred income taxes, as accumulated other  comprehensive  income (loss)
in  shareholders'  equity.  Realized gains and losses on sales of securities are
based upon the amortized cost of the specific security sold.

Loans

     Loans are  either  secured or  unsecured  based on the type of loan and the
financial  condition of the borrower.  Repayment is generally expected from cash
flow or proceeds from the sale of selected assets of the borrower. BOK Financial
is exposed to risk of loss on loans due to the  borrower's  difficulties,  which
may arise from any number of factors  including  problems  within the respective
industry or local economic  conditions.  Access to  collateral,  in the event of
borrower default,  is reasonably assured through adherence to applicable lending
laws and through sound lending standards and credit review procedures.
     Interest is accrued at the applicable interest rate on the principal amount
outstanding.  Loans are placed on  nonaccrual  status  when,  in the  opinion of
management,  full  collection of principal or interest is  uncertain,  generally
when the  collection  of  principal  or  interest  is 90 days or more  past due.
Interest previously accrued but not collected is charged against interest income
when the loan is placed on nonaccrual  status.  Payments on nonaccrual loans are
applied to principal or reported as interest  income,  according to management's
judgment as to the collectibility of principal.  Loan origination and commitment
fees,  and direct loan  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 adequacy of the reserve for loan losses is assessed by management based
upon an ongoing quarterly  evaluation of the probable  estimated losses inherent
in the portfolio,  and includes  probable losses on both  outstanding  loans and
unused  commitments  to provide  financing.  A consistent  methodology  has been
developed that includes reserves assigned to specific criticized loans,  general
reserves that are based upon a statistical  migration analysis for each category
of loans,  and other  allocated  reserves  that are based  upon an  analysis  of
current economic conditions,  loan  concentrations,  portfolio growth, and other
relevant  factors.  The  reserve  for loan  losses  related  to  loans  that are
identified for evaluation in accordance  with Statement of Financial  Accounting
Standards  No. 114,  "Accounting  by Creditors  for  Impairment of a Loan" ("FAS
114"),  is based on  discounted  cash flows using the loan's  initial  effective
interest  rate or the  fair  value  of the  collateral  for  certain  collateral
dependent  loans.  Loans are considered to be impaired when it becomes  probable
that BOK  Financial  will be unable to collect all amounts due  according to the
contractual terms of the loan agreement. This is substantially the same criteria
used to  determine  when a loan  should  be placed on  nonaccrual  status.  This
evaluation is inherently  subjective as it requires material estimates including
the amounts and timing of future cash flows  expected to be received on impaired
loans that may be susceptible to significant change.
     In accordance with the provisions of FAS 114, management has excluded small
balance,  homogeneous loans from the impairment evaluation specified in FAS 114.
Such loans include 1-4 family  mortgage loans,  consumer  loans,  and commercial
loans with committed  amounts less than $1 million.  The adequacy of the reserve
for loan  losses  applicable  to these loans is  evaluated  in  accordance  with
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.

Asset Securitization

     BOK Financial securitizes and sells pools of assets. These transactions are
designed to comply with the  requirements  of Statement of Financial  Accounting
Standard No. 125,  "Accounting  for Transfers and Servicing of Financial  Assets
and  Extinguishments  of  Liabilities,"  ("FAS 125") for treatment as a sale. As
part of these sales,  BOK  Financial  may retain the right to service the assets
and a residual  interest in excess cash flows generated by the assets.  The fair
value of these retained assets is determined by a discounting of expected future
net  cash  to  be  received  using  assumed  market  interest  rates  for  these
instruments. Servicing rights are carried at the lower of amortized cost or fair
value. A valuation allowance is provided when amortized cost of servicing rights
exceeds fair value.  Residual  interests  are carried at fair value.  Changes in
fair values are recorded in income.

Real Estate and Other Repossessed Assets

     Real estate and other repossessed  assets are assets acquired in partial or
total  forgiveness of debt. These assets are carried at the lower of cost, which
is  determined by fair value at date of  foreclosure  or current fair value 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.   During  1998,  BOK  Financial   adopted  Statement  of  Position  98-1,
"Accounting for the Cost of Computer Software Developed or Obtained for Internal
Use." The statement  requires the  capitalization  of certain costs  incurred to
acquire,  develop and install computer  software subject to certain  conditions.
Previously,  only costs to acquire software were  capitalized.  All other costs,
including installation costs, were charged to expense. Upgrades and enhancements
to existing  software  will  generally  continue  to be charged to expense.  The
current year effect of this statement was not material.

Mortgage Servicing Rights

     Capitalized  mortgage  servicing rights are carried at the lower of cost or
fair  value.  Cost  is  determined  by  acquisition   amount  minus  accumulated
amortization  plus/minus  deferred  loss/gain on hedges and changes in valuation
allowances,  if any.  Amortization  is determined in proportion to the projected
cash flows over the estimated lives of the servicing portfolios. The actual cash
flows are dependent  upon the  prepayment  of the mortgage  loans and may differ
significantly from the estimates.
     Fair  value is  determined  by  discounting  the  estimated  cash  flows of
servicing revenue,  less projected servicing costs, using  risk-adjusted  rates,
which is the assumed market rate for these instruments.  Prepayment  assumptions
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 capitalized servicing rights
is based upon an interest rate stratification.  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 net amortized cost of each
interest rate strata  exceeds the  calculated  fair value.
     Originated  mortgage  servicing  rights are recognized when either mortgage
loans are  originated  pursuant to an existing plan for sale or, if no such plan
exists, when the mortgage loans are sold.  Substantially all fixed rate mortgage
loans originated by BOK Financial are sold under existing commitments.  The fair
value of the  originated  servicing  rights is  determined at closing based upon
current market rates.

<PAGE> 33

Hedging of Mortgage Servicing Rights

     BOK  Financial  enters into futures  contracts  and call and put options on
futures contracts to hedge against the risk of loss on mortgage servicing rights
due to accelerated  loan  prepayments  during periods of falling interest rates.
Contracts on underlying securities which are expected to have a similar duration
to the mortgage  servicing  portfolio,  such as 10-year U.S. Treasury notes, are
used for these hedges.  The  combination of contracts  selected is based upon an
analysis of the expected  range of market value changes over a probable range of
interest  rates to achieve a high degree of correlation  between  changes in the
fair value of the mortgage  servicing  rights and changes in the market value of
the  contracts.  These  contracts  are  designated  as hedges on the trade date.
Transaction fees are charged to expense when incurred. Premiums paid or received
on option  contracts are deferred and amortized  against  mortgage banking costs
over the life of the options.  Both  unrealized and realized gains and losses on
futures  contracts and option  contracts are deferred as part of the capitalized
mortgage  servicing  rights.  These deferred gains and losses are amortized over
the estimated life of the loan servicing portfolio. Changes in the fair value of
the contracts and changes in the market value of the mortgage  servicing  rights
are reviewed at least monthly to determine  whether a high degree of correlation
exists on a statistically valid basis. If correlation  criteria are not met, the
contracts are no longer  accounted for as a hedge.  In such  circumstances,  any
remaining unamortized deferred gains or losses are recognized in current income.

Interest Rate Swaps and Forward Commitments

     Interest  rate swaps and  forward  sales  contracts  are used as part of an
interest rate risk management  strategy.  Interest rate swaps are used primarily
to modify  the  interest  expense of certain  long-term,  fixed rate  assets and
liabilities.  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  obligations,  any realized or unrealized gain or loss from
the swaps would be recognized in income coincident with the redemption. The fair
value of the swap  agreements  and  changes  in the fair value due to changes in
market interest rates are not recognized in the financial statements.
     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

     BOK Financial utilizes the liability method in accounting for income taxes.
Under this method, deferred tax assets and liabilities are determined based upon
the difference  between the values of the assets and liabilities as reflected in
the  financial  statement and their related tax basis using enacted tax rates in
effect for the year in which the  differences  are  expected to be  recovered or
settled.  As changes in tax law or rates are  enacted,  deferred  tax assets and
liabilities are adjusted through the provision for income taxes.
     BOK Financial  and its  subsidiaries  file  consolidated  tax returns.  The
subsidiaries  provide for income taxes on a separate return basis,  and remit to
BOK Financial amounts determined to be currently payable.

Employee Benefit Plans

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

Executive Benefit Plans

     BOK Financial has elected to follow Accounting Principles Board Opinion No.
25,  "Accounting  for  Stock  Issued  to  Employees,"  ("APB  25")  and  related
interpretations  in accounting  for its employee  stock  options.  Under APB 25,
because the exercise  price of employee stock options equals the market price of
the underlying  stock options on the date of grant, no  compensation  expense is
recorded. BOK Financial has adopted the disclosure-only  provisions of Statement
of  Financial   Accounting   Standards  No.  123,  "Accounting  for  Stock-Based
Compensation," ("FAS 123"), included in Note 12.

Fiduciary Services

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

Comprehensive Income

     As of  January  1, 1998,  BOK  Financial  adopted  Statement  of  Financial
Accounting Standards No. 130, "Reporting  Comprehensive Income" ("FAS 130"). FAS
130 establishes new rules for reporting and display of comprehensive  income and
its  components;  however,  the  adoption  of  FAS  130  had  no  impact  on BOK
Financial's  net income or  shareholders'  equity.  FAS 130 requires  unrealized
gains  or  losses  on  available-for-sale  securities  to be  included  in other
comprehensive  income.  The components of comprehensive  income are disclosed in
the Consolidated Statements of Changes in Shareholders' Equity.

<PAGE> 34

Segment Disclosures

     On  December  31,  1998,  BOK  Financial  adopted  Statement  of  Financial
Accounting  Standards No. 131,  "Disclosures about Segments of an Enterprise and
Related  Information"  ("FAS 131"). FAS 131 established  standards for reporting
information about operating segments and related  disclosures about products and
services,  geographic  areas and major  customers.  BOK Financial  operates five
principal  lines of business - corporate  banking,  consumer  banking,  mortgage
banking,  trust  services and regional  banks which account for more than 75% of
total revenue.  The  disclosures  required by FAS 131 have been included in Note
17.

Effect of Pending Statements of Financial Accounting Standards

     In June 1998, the Financial Accounting Standards Board issued Statement No.
133, "Accounting for Derivative Instruments and Hedging Activities" ("FAS 133").
FAS 133,  which  requires  BOK  Financial to recognize  all  derivatives  on the
balance  sheet at fair value,  is effective for years  beginning  after June 15,
2000.  FAS 133 permits early  adoption as of the beginning of any fiscal quarter
that begins after June 1998.  BOK  Financial  expects to adopt FAS 133 effective
January 1, 2001.  Derivatives that are not hedges must be adjusted to fair value
through  income.  If the  derivative is a hedge,  depending on the nature of the
hedge,  changes in the fair value of  derivatives  are either offset against the
change in fair value of the assets,  liabilities,  or firm  commitments  through
earnings or  recognized in other  comprehensive  income until the hedged item is
recognized in earnings.  The  ineffective  portions of a derivative's  change in
fair value will be immediately recognized in earnings. BOK Financial has not yet
determined  what effect the adoption of this  statement will have on its results
of operations or financial positions.


(2) ACQUISITIONS

     On  May  14,  1999,  BOK  Financial  paid  $26.8  million  to  acquire  all
outstanding  common shares of Chaparral  Bancshares,  Inc. and its subsidiaries,
including Canyon Creek National Bank,  (collectively "Canyon Creek"). On June 2,
1999,  BOK  Financial  paid $17.0  million to acquire all  outstanding  stock of
Mid-Cities Bancshares, Inc. and its subsidiaries (collectively "Mid-Cities"). On
June 15, 1999, BOK Financial paid $32.0 million to acquire all outstanding stock
of Swiss Avenue State Bank ("Swiss").
     On December 4, 1998, BOK  Financial,  through Bank of  Albuquerque,  paid a
premium of $34 million to Bank of America to assume the  deposits and to acquire
the  premises  and  equipment  and certain  loans at 17  branches,  primarily in
Albuquerque, New Mexico.
     During the first quarter of 1997, BOK Financial  completed the acquisitions
of Park Cities Bancshares, Inc. and its subsidiary,  First National Bank of Park
Cities,  Dallas, Texas (collectively "Park Cities") and First Texcorp,  Inc. and
its subsidiary First Texas Bank, Dallas,  Texas (collectively "First Texas"). On
February 12, 1997,  BOK Financial  issued notes  totaling  $10.9 million and $40
million in cash to acquire all  outstanding  common shares of Park Cities and on
March 4, 1997,  BOK  Financial  paid $39.3  million to acquire  all  outstanding
common shares of First Texas.
     All of the above  transactions were accounted for by the purchase method of
accounting.  Allocation of the purchase price to the net assets acquired in 1999
and the aggregate acquisitions in 1998 and 1997 were as follows (in thousands):

    The  majority  of  the   commercial   and  consumer  loan   portfolios   and
approximately  63% of the residential  mortgage loan portfolio  (excluding loans
held for  sale)  are loans to  businesses  and  individuals  in  Oklahoma.  This
geographic  concentration  subjects the loan  portfolio to the general  economic
conditions within this area.
    Within  the  commercial  loan   classification,   loans  to   energy-related
businesses total $606.6 million,  or 13% of total loans.  Other notable segments
include  wholesale/  retail,  $407.8  million;  manufacturing,  $344.2  million;
agriculture,  $173.7 million,  which includes $143.9 million loans to the cattle
industry;  and services,  $807.2  million,  which include nursing homes of $84.6
million, hotels of $108.0 million and healthcare of $110.3 million.
    Approximately  53% of  commercial  real  estate  loans are  secured  by
properties  located  in  Oklahoma,  primarily  in the  Tulsa  or  Oklahoma  City
metropolitan  areas.  An  additional  12% of  commercial  real estate  loans are
secured by property  located in Texas.  The major components of these properties
are multifamily residences,  $257.2 million;  construction and land development,
$249.2 million; retail facilities,  $169.4 million; and office buildings, $207.5
million.
     Included in loans at December 31 are loans to executive officers, directors

     At December 31, 1999, 1998 and 1997, respectively,  the recorded investment
in loans that are  considered  to be impaired  under FAS 114 was $15.6  million,
$11.3  million  and $16.8  million  (all of which were on a  nonaccrual  basis).
Included in this amount at December 31, 1999, is $9.1 million of impaired  loans
for which the related  specific reserve for loan losses is $2.5 million and $6.6
million  that did not have a  specific  related  reserve  for  loan  losses.  At
December 31, 1998 and 1997, respectively,  this amount included $2.7 million and
$2.6 million,  of impaired loans for which the related allowance for credit loss
was $1.4  million  and  $919  thousand  and  $8.6  million  and  $14.2  million,
respectively,  that did not have a related  allowance  for  credit  losses.  The
average  recorded  investments in impaired loans during the years ended December
31, 1999,  1998 and 1997 were  approximately  $15.3  million,  $13.8 million and
$19.5 million, respectively. Interest income recognized on impaired loans during
1999, 1998 and 1997 was not significant.

     During 1999,  BOK Financial sold  approximately  $100 million of automobile
loans and  retained  the right to service  the loans and a residual  interest in
certain excess cash flows generated by the loans.  The proceeds of the sale were
provided by the issuance of debt  certificates  that totaled $95.9 million by an
independent  special purpose entity.  These retained interests are being carried
on the books in  accordance  with FAS 125. A spread  account is  maintained by a
trustee to hold excess  cash  received.  Funds will be released  from the spread
account to BOK  Financial  once certain  criteria are met. At December 31, 1999,
the carrying  values of the  servicing  rights asset and residual  interest were
$343  thousand  and $9.8  million,  respectively.  Significant  information  and
assumptions  used to  determine  the value of these  assets at December 31, 1999
were:

Current outstanding loan principal            $56.7 million
Average interest rate on loans sold            11.44%
Current  outstanding  debt  certificates      $52.6 million
Interest rate on debt certificates              6.07%
Current spread account balance                $ 4.6 million
Estimated remaining life including Prepayments   30 months

    Depreciation expense of premises was $13.3 million,  $8.6 million and
$8.1  million  for the years  ended  December  31,  1999,  1998 and 1997,
respectively.

(7) MORTGAGE BANKING ACTIVITIES

     BOK  Financial  engages  in  mortgage-banking  activities  through  the BOk
Mortgage Division of BOk. Residential mortgage loans held for sale totaled $57.1
million and $100.3 million and  outstanding  mortgage loan  commitments  totaled
$123.2 million and $239.0 million,  respectively, at December 31, 1999 and 1998.
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,  1999,  forward  sales
contracts totaled $72.3 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, 1999, BOk owned the rights to service 94,352 mortgage loans
with outstanding  principal  balances of $7.0 billion,  including $107.4 million
serviced for BOk, and held related  funds for  investors  and borrowers of $93.6
million. The weighted average interest rate and remaining term was 7.46% and 272
months, respectively.  Mortgage loans sold with recourse totaled $4.2 million at
December  31,  1999.  At  December  31,  1998,  BOk owned the  rights to service
mortgage  loans with  outstanding  principal  balances of $6.4  billion and held
related funds for investors and borrowers of $153.8 million.
     The  portfolio of mortgage  servicing  rights  exposes BOk to interest rate
risk.  During  periods of falling  interest  rates,  mortgage  loan  prepayments
increase.  This reduces the value of the mortgage  servicing rights.  BOk uses a
combination of futures  contracts and options  related to 10-year U.S.  Treasury
securities to hedge this risk. The value of these derivative  instruments  moves
inversely to the value of the mortgage servicing rights. See Note 1 for specific
accounting policies for mortgage servicing rights and the related hedges.

     Other  borrowings at December 31, 1999 included  $816.3 million in advances
from the  Federal  Home Loan Bank.  These  advances,  which are used for funding

in 2001,  $17.5 million mature in 2002,  $54 thousand  mature in 2003, and $38.5
million mature thereafter.  In accordance with policies of the Federal Home Loan
Bank, BOK Financial has granted a blanket pledge of eligible  assets  (generally
unencumbered U.S. Treasury and mortgage-backed  securities, 1-4 family loans and
multifamily loans) as collateral for these advances. The unused credit available
to BOK  Financial at December 31, 1999  pursuant to the Federal Home Loan Bank's
collateral policies is $78.0 million.

     BOK  Financial has a revolving,  unsecured  credit  agreement  from certain
banks at December 31, 1999 with available credit of $125 million that expires in
November 2002;  $105 million was  outstanding at year-end.  Interest is based on
either LIBOR or a base rate,  plus a defined  margin which is  determined by the
amount of principal  outstanding and BOK Financial's debt rating.  The base rate
is defined as the  greater of either the daily  federal  funds rate or the prime
rate.  Interest  is paid  quarterly.  Facility  fees are paid  quarterly  on the
average  daily  undrawn  commitment at a rate of 0.20% - 0.30 % as determined by
BOK Financial's current debt rating. This credit agreement also includes,  among
other things,  certain restrictive covenants relative to additional  borrowings,
capital levels, maintenance of certain net worth ratios and dividends on capital
stock.
     BOK Financial filed a shelf registration  statement with the Securities and
Exchange  Commission  for the  issuance  of up to $250  million  of senior  debt
securities  during the fourth quarter of 1998.  These securities will be direct,
unsecured  obligations,  and are not  insured by the Federal  Deposit  Insurance
Corporation or guaranteed by any governmental agency. None of this debt has been
issued at December 31, 1999. BOk issued $150 million of subordinated  debentures
in 1997 at a discounted  cost of 7.2%,  which had a balance at December 31, 1999
of $148.6 million and will mature in 2007.  Interest expense on the subordinated
debenture  was reduced by net income from  interest  rate swaps of $1.5  million
during 1999.
     Funds purchased generally mature within one to 90 days from the transaction
date.  At December 31, 1999,  securities  sold under  agreements  to  repurchase

     As  of  December  31,  1997,  the  Internal   Revenue  Service  closed  its
examination  of BOk and BOK  Financial  for 1992 and  1993,  respectively.  As a
result of the  outcome of these  examinations,  BOK  Financial  reduced  its tax
reserve by $9 million,  which was credited  against  current  federal income tax
expense in 1997.  In  addition,  the  Internal  Revenue  Service  has closed its
examination  for  1994  and  1995  with  no  material  impact  on the  financial
statements.  The Internal  Revenue Service closed its examination of 1996 during
the  first  quarter  of 2000.  This  examination  had no  adverse  impact on the
financial  statements and BOK Financial is evaluating the impact, if any, on its
tax reserve.

     The above income tax analysis has been  restated to include the  operations
of First Muskogee. Additionally, for income tax purposes, First Muskogee elected
to be  treated as an S  Corporation  effective  January  1,  1997.  This type of
corporation does not generally pay income taxes and its income and expense items
are passed through to its shareholders.  For this reason, First Muskogee did not
pay  federal or state  income  taxes for the years ended  December  31, 1998 and
1997. If First  Muskogee had been required to pay income taxes in those years as
a  regular  corporation,  such  amounts  would  not have  been  material  to the
consolidated results of operations of BOK Financial.

     Assets of the Pension Plan consist  primarily of shares in cash  management
funds,  common stock and bond funds, and guaranteed  investment  contract funds.
Benefits are based on the employee's age and length of service.
     Employee contributions to the Thrift Plans, defined contribution plans, are
matched  by BOK  Financial  up to 5% 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 Plans totaled
$2.4  million,   $1.9  million  and  $1.5  million  for  1999,  1998  and  1997,
respectively.
     BOK Financial  also  sponsors a defined  benefit  post-retirement  employee
medical  plan which pays 50 percent of annual  medical  insurance  premiums  for
retirees  who meet certain age and service  requirements.  Assets of the retiree
medical plan consist primarily of shares in a cash management fund.  Eligibility
for  the  post-retirement  plan is  limited  to  current  retirees  and  certain
employees currently age 60 or older.
     Under various performance incentive plans,  participating  employees may be
granted  awards  based on defined  formulas  or other  criteria.  Earnings  were
charged $19.3 million in 1999,  $14.9 million in 1998 and $10.4 million in 1997,
for such awards.

(12) EXECUTIVE BENEFIT PLANS

     The Board of Directors of BOK Financial  has approved  various stock option
plans.  The number of options  awarded and the  employees to receive the options
are  determined  by the  Chairman  of the Board and the  President,  subject  to
approval of the Board of Directors or a committee thereof.
     Options  awarded  under these  plans are  subject to vesting  requirements.
Generally,  one-seventh  of the options  awarded vest  annually and expire three
years after vesting.
     The following table presents options outstanding during 1998 and 1999 under
these plans:

     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:

                                         1999      1998      1997
                                      --------- --------- ---------

  Average  risk-free interest rate        6.12%     4.71%     5.72%
  Dividend yield                          None      None      None
  Volatility factors                      .192      .198      .200
  Weighted-average expected life       7 years   7 years   7 years

     The  weighted-average  fair value of options  granted during 1999, 1998 and
1997  was  $7.34,  $7.00  and  $5.93,  respectively.  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:

                                     1999(1)   1998(1)   1997(1)
                                   -------------------------------

  Pro forma net income               $87,736   $78,504   $67,478
  Pro forma earnings per share:

(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 $3.2 million. BOk subleases portions of
its space for annual  rents of $406  thousand in 2000 and $22 thousand for years
2001 through 2003.  Net rent expense on this lease was $2.8 million in 1999, and
$2.7 million in 1998 and 1997.  Total rent expense for BOK  Financial  was $10.2
million in 1999, $9.0 million in 1998 and $7.7 million in 1997.
     At December 31, 1999,  the future  minimum lease payments for equipment and
premises under operating  leases were as follows:  $10.8 million in 2000,  $10.1
million in 2001,  $8.8 million in 2002,  $6.6  million in 2003,  $5.9 million in
2004 and a total of $106.7 million thereafter.
     BOk and  Williams  Companies,  Inc.  guaranteed  30 percent and 70 percent,
respectively,  of the $15.7  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 $273 thousand in 1999,
$281 thousand in 1998 and $226 thousand in 1997.
     The Federal Reserve Bank requires member banks to maintain  certain minimum
average cash balances. These balances were approximately $164.6 million for 1999
and $90.8 million for 1998.


(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, 1999, outstanding  commitments
totaled  $2.4  billion.  Since some of the  commitments  are  expected to expire
before  being  drawn  upon,  the total  commitment  amounts  do not  necessarily
represent future cash requirements.  BOK Financial uses the same credit policies
in making  commitments as it does loans. The amount of collateral  obtained,  if
deemed necessary, is based on management's credit evaluation of the borrower.
     Standby letters of credit are conditional  commitments  issued to guarantee
the  performance of a customer to a third party.  Since the credit risk involved
in issuing standby letters of credit is essentially the same as that involved in
extending  loan  commitments,  BOK  Financial  uses the same credit  policies in
evaluating the  creditworthiness  of the customer.  Additionally,  BOK Financial
uses the same evaluation  process in obtaining  collateral on standby letters of
credit  as it does for loan  commitments.  At  December  31,  1999,  outstanding
standby letters of credit totaled $155.0 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,  1999,  outstanding  commercial  letters of credit
totaled $4.7 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 of certain  long-term,  fixed rate
assets and liabilities.  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, 1999, the notional  amount of BOK  Financial's  interest rate swaps
totaled  $575.6 million with related  credit  exposure,  represented by the fair
value of the contracts,  of $9.2 million.  During 1999 and 1998, income from the
swaps  exceeded  costs by $1.4  million and $1.7  million,  respectively,  which
reduced  interest  expense.  Scheduled  repricing  periods  for the swaps are as
follows (notional value in thousands):

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

     The  expiration  dates of the swap  contracts  are  designed  to match  the
estimated maturity dates of the underlying assets and liabilities and matures as
follows:  $4.2 million in 2001,  $201.6 million in 2002,  $39.5 million in 2003,
$22.8  million in 2004,  $8.0  million in 2005,  $16.5  million in 2006,  $164.3
million in 2007, $35.5 million in 2008 and $83.2 million in 2009.
     BOK Financial utilized  securities forward sales contracts  associated with
its mortgage banking activities as described in Note 7.

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 41 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 1999, 1998 and
1997,  57,340 shares,  68,765 shares and 107,230  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 1999,  1998 and
1997,  based on average market price,  as defined,  for a 65 business day period
preceding declaration.
     Various  officers own 125 nonvoting  units in an entity owned by BOk. These
units are eligible  for an annual,  cumulative  distribution  of $8 per unit and
have a preferred value upon liquidation of $100 per unit.

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 and BOK  Financial's
credit agreement restricts the payment of dividends by the holding company.
     During 1999, 1998 and 1997, 3% dividends payable in shares of BOK Financial
common  stock were  declared  and paid.  The shares  issued were valued at $30.6
million,  $30.3 million and $27.4  million,  respectively,  based on the average
closing bid/ask prices on the day preceding declaration.  Presently,  management
plans to  recommend  continued  payment of annual  dividends in shares of common
stock.
     All share and per share  amounts for  previous  years  presented  have been
retroactively  adjusted for a two-for-one  stock split effected in the form of a
stock dividend  declared January 26, 1999 for stockholders of record on February
8, 1999.

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, 1999, BOK Financial's  subsidiary
banks could  declare  dividends up to $81.8  million  without  prior  regulatory
approval.  The subsidiary  banks declared and paid dividends of $63.0 million in
1999, $26.3 million in 1998 and $69.8 million in 1997.
     Loans  to a  single  affiliate  may  not  exceed  10.0%  and  loans  to all
affiliates may not exceed 20.0% of unimpaired  capital and surplus,  as defined.
Additionally, loans to affiliates must be fully secured. As of December 31, 1999
and 1998,  these loans totaled $35.3  million and $40.4  million,  respectively,
including $9.2 million and $27.9 million to  consolidated  entities.  Total loan
commitments to affiliates at December 31, 1999 were $82.7 million.

Regulatory Capital

     BOK Financial and its banking  subsidiaries  are subject to various capital
requirements  administered  by the  federal  banking  agencies.  Failure to meet
minimum  capital  requirements  can  initiate  certain  mandatory,  and possibly
additional  discretionary,  actions  by  regulators  that  could have a material
effect  on  BOK  Financial's  operations.  These  capital  requirements  include
quantitative  measures of assets,  liabilities,  and certain  off-balance  sheet
items.  The capital  standards are also subject to qualitative  judgments by the
regulators about components, risk weightings and other factors.
     For a banking institution to qualify as well capitalized, its Tier I, Total
and Leverage capital ratios must be at least 6%, 10% and 5%, respectively.  Tier
I  capital  consists  primarily  of  common  stockholders'   equity,   excluding
unrealized gains or losses on available for sale securities, less goodwill, core
deposit premiums,  and certain other intangible  assets.  Total capital consists
primarily of Tier I capital plus preferred stock, subordinated debt and reserves
for loan losses, subject to certain limitations.  All of BOK Financial's banking
subsidiaries exceeded the regulatory definition of well capitalized.

(17) REPORTABLE SEGMENTS

     BOK Financial  operates four principal  lines of business under its Bank of
Oklahoma franchise:  corporate banking,  consumer banking,  mortgage banking and
trust services.  It also operates a fifth  principal line of business,  regional
banks,  which includes all banking  functions for Bank of  Albuquerque,  Bank of
Arkansas  and Bank of Texas.  These five  principal  lines of business  combined
account for approximately 86% of total revenue.  Other lines of business include
the TransFund ATM system and BOSC, Inc. The Corporate  Banking segment  consists
of eight  operating units that provide credit and lease  financing,  deposit and
cash  management,  and  international  collection  services  to  commercial  and
industrial  customers  and to  other  financial  institutions  in  Oklahoma  and
surrounding states. The Consumer Banking segment consists of two operating units
which  provide  direct and  indirect  consumer  loans and  deposit  services  to
individuals primarily within Oklahoma.  The Mortgage Banking segment consists of
two  operating  units that  originate  a full range of  mortgage  products  from
federally  sponsored  programs to "jumbo  loans" on higher  priced  homes in BOK
Financial's  primary market areas.  The Mortgage  Banking  segment also services
mortgage  loans acquired from  throughout the United States.  The Trust Services
segment consists of one operating unit that provides  financial services to both
individual and corporate clients. Individual financial services include personal
trust  management,  administration  of estates and  management of investment and
custodial  accounts.  Individual  financial  services also includes  lending and
investment services to select individuals.  Corporate financial services include
administration of employee benefit plans, transfer and paying agent services and
investment advisory services.  Regional Banks include Bank of Arkansas,  Bank of
Albuquerque  and Bank of Texas.  Bank of Texas  includes  Canyon Creek  National
Bank,  Mid-Cities  National Bank and Swiss Avenue State Bank which were acquired
in 1999 and  which  will be  merged  into  Bank of  Texas  in 2000.  Information
regarding  regional  banks  was  included  in total  nonreportable  segments  in
previous years.
     BOK Financial  identifies  reportable  segments by type of service provided
for the Mortgage Banking and the Trust Services segments and by type of customer
for the Corporate  Banking and Consumer  Banking  segments.  Regional  Banks are
identified by legal entity. Operating results are adjusted for intercompany loan
participations and allocated service costs and management fees.
     BOK Financial  evaluates  performance and allocates  resources based upon a
measurement of performance  after the allocation of certain  indirect  expenses,
taxes and capital cost. Capital is assigned to the lines of business based on an
internal  allocation  method that reflects  management's  assessment of risk. An
additional  amount of capital is assigned to the  regional  banks based upon BOK
Financial's  investment  in  these  entities.  The  accounting  policies  of the
reportable   segments  generally  follow  those  described  in  the  summary  of
significant  account  policies  except  interest  income is  reported on a fully
tax-equivalent  basis,  loan losses are based on actual net amounts  charged off
and the  amortization of intangible  assets is generally  excluded.  The cost of
funds  provided  from one  segment to another is  transfer-priced  at rates that
approximate market for funds with similar duration. Assessment of performance is
based on net interest revenue after internal funds transfer pricing.
     Nonreportable  business  segments  include  TransFund  and BOSC,  Inc.  The
sources of revenue in these segments  include  interest,  commissions  earned on
securities transactions,  securities trading gains or losses, and fees earned on
various banking activities, including merchant discounts and interchange fees.
     BOK Financial has not made any significant  investments in long-term assets
other than financial  instruments,  including core deposit intangible assets and
purchased mortgage servicing rights.  Substantially all revenue is from domestic
customers.  No  single  external  customer  accounts  for more than 10% of total
revenue.

</TABLE>

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

<PAGE> 53

           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 $12.0  million and $9.6 million at December 31, 1999
and 1998,  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.  Statement
of  Financial  Accounting  Standard  No. 107,  "Disclosures  about Fair Value of
Financial Instruments," ("FAS 107") defines the estimated fair value of deposits
with no stated maturity,  which includes demand deposits,  transaction deposits,
money  market  deposits  and savings  accounts,  to equal the amount  payable on
demand.  Although market premiums paid reflect an additional value for these low
cost deposits,  FAS 107 prohibits  adjusting fair value for the expected benefit
of these  deposits.  Accordingly,  the positive  effect of such  deposits is not
included in this table.

Other Borrowings and Subordinated Debenture

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

Off-Balance-Sheet Instruments

     The fair values of commercial  loan  commitments  and letters of credit are
based on fees currently  charged to enter into similar  agreements,  taking into
account  the  remaining  terms  of the  agreements.  The  fair  values  of these
off-balance-sheet  instruments  were not  significant  at December  31, 1999 and
1998. Residential mortgage loan commitments are included in determining the fair
value of the  mortgage  loans held for sale.  The fair values of  interest  rate
swaps  are  based on  pricing  models  using  current  assumptions  to arrive at
replacement  cost.  The  estimated  fair value of interest  rate swaps were $9.2
million and $10.2 million at December 31, 1999 and 1998, respectively.
