                    INFORMATION TO BE INCLUDED IN THE REPORT

ITEM 2.02.  Results of Operations and Financial Condition.

     BOK  Financial  Corporation  (the  "Company")  has  completed a preliminary
review of  internal  asset  quality  as part of its  regular  quarterly  control
process.  As a result  of that  review,  the  Company  expects  credit  costs to
increase compared to the first quarter of 2008. The Company currently expects to
record a credit loss provision for the second quarter of between $30 million and
$35 million and expects net loan charge-offs to be within a range of $12 million
to $14 million.  The provision for credit losses was $17.6 million and net loans
charged off totaled $8.9 million for the first quarter of 2008.

     Non-performing  assets are  expected  to be between  $150  million and $165
million at quarter end, up from $126  million at March 31, 2008.  Non-performing
assets include  approximately $8 million of mortgage loans subject to government
guarantee  and $14 million of assets  subject to a cash escrow for credit losses
from a recent  acquisition.  The increase in non-performing  assets includes $17
million of residential  real estate  development and  construction  exposures in
Arizona,  including  Tucson,  a market that has more  recently  been impacted by
adverse real estate trends.  Arizona real estate  development and construction
loans represent  approximately $152 million of the Company's $12.7 billion total
loan portfolio. The net loan charge-offs include $3.9 million from one credit in
the services  segment of the Oklahoma  loan  portfolio.  The  remaining net loan
charge-offs are individually less than $1 million.

     The Company  expects Other Real Estate Owned to continue to increase in the
coming  quarters  as it tends to hold  properties  rather than elect a bulk sale
exit strategy at distressed  prices.  The Company will compare the cost of carry
for each property to the return  potential from holding the property in order to
maximize shareholder value.

     In  addition,  the Company  expects to record a quarterly  charge  within a
range of $2.5 million to $3.0 million related to certain  community  development
residential  mortgage loans that were sold with  recourse.  These mortgage loans
were underwritten to standards approved by U.S. government  agencies,  including
full  documentation.  However,  these loans generally required a smaller initial
down payment and have a greater loss  exposure.  The principal  balance of these
loans  subject  to  recourse   obligations   is   approximately   $392  million;
approximately  70% of these loans are to borrowers in Oklahoma.  The reserve for
credit risk from these loans is expected to total  approximately $7.5 million at
the end of the quarter.  The Company  suspended  originating  and selling  these
types of loans in the first quarter of 2008.

     The Company  completed a preliminary  review of its  investment  securities
portfolio for Other Than Temporary  Impairment.  The Company does not expect any
impairment charges in the second quarter as a result of that review.

     The Company  expects to release  earnings for the second quarter of 2008 on
Tuesday, July 15th.

materially  differ  from  what  is  expected,  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 consumer  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.
