              Annual Earnings Total $201 Million or $2.96 per Share

TULSA, Okla. (Wednesday January 27, 2010) - BOK Financial Corporation reported
net income for the fourth quarter of 2009 of $42.8 million or $0.63 per diluted
share compared to $50.7 million or $0.75 per diluted share for the third quarter
of 2009 and $35.4 million, or $0.52 per diluted share for the fourth quarter of
2008.

Net income for 2009 totaled $200.6 million or $2.96 per diluted share compared
to $153.2 million or $2.27 per diluted share for 2008.

"BOK Financial continued to produce solid earnings in 2009 despite economic
challenges," said President and CEO Stan Lybarger. "We remained committed to a
strategy of diversified revenue sources, well-managed operating expenses and
controlled growth that focuses on long-term shareholder value. Our capital base
which was built on retained earnings, not government assistance, has us well
positioned for the future."

Highlights of fourth quarter of 2009 included:

o    Net interest revenue totaled $184.5 million, up $4.0 million over the third
     quarter of 2009.  Net interest  margin was 3.64% for the fourth  quarter of
     2009 and 3.63% for the third quarter of 2009.

o    Fees and commissions revenue totaled $115.9 million, down $4.0 million from
     the previous  quarter due primarily to a $4.7 million decrease in brokerage
     and trading revenue.

o    Operating  expenses,  excluding  changes  in the  fair  value  of  mortgage
     servicing  rights,  totaled $181.7 million,  up $6.0 million from the prior
     quarter.  Mortgage  banking  costs,  occupancy  costs  and net  losses  and
     expenses of repossessed assets increased over the prior quarter.  Personnel
     expenses decreased due to lower incentive compensation expense.

o    Combined  reserves  for  credit  losses  totaled  $306  million or 2.72% of
     outstanding  loans at December 31,  2009,  up from $293 million or 2.52% of
     outstanding  loans  at  September  30,  2009.  Net  loans  charged  off and
     provision  for  credit  losses  were  $35.0  million  and  $48.6   million,
     respectively for the fourth quarter of 2009.

o    Non-performing  assets totaled $484 million or 4.24% of  outstanding  loans
     and  repossessed  assets at December  31,  2009,  down from $490 million or
     4.19% of outstanding  loans and  repossessed  assets at September 30, 2009.
     Non-accruing  loans  decreased  $43  million  and  real  estate  and  other
     repossessed assets increased $40 million during the fourth quarter.

o    Available for sale securities totaled $8.9 billion at December 31, 2009, up
     $513  million   since   September  30  due  to  purchases  of   residential
     mortgage-backed    securities   issued   by   U.S.   government   agencies.
     Other-than-temporary   impairment   charges  on  certain   privately-issued
     residential  mortgage  backed  securities  reduced  pre-tax income by $14.5
     million during the fourth quarter of 2009.

o    Outstanding  loan balances  were $11.3  billion at December 31, 2009,  down
     $332 million since September 30, 2009. All major loan categories  decreased
     during the fourth quarter largely due to reduced customer demand and normal
     repayment trends.

o    Average deposit balances totaled $15.6 billion for the fourth quarter 2009,
     up $444 million from the third  quarter of 2009.  Total period end deposits
     grew $423 million in the fourth quarter of 2009 to $15.5 billion. Growth in
     demand and  interest-bearing  transaction  deposits was partially offset by
     decreases in higher-costing time deposits.

o    Tangible  common equity ratio increased to 7.99% at December 31, 2009, from
     7.78% at September 30, 2009 largely due to retained  earnings  growth.  The
     tangible common equity ratio is a non-GAAP measure of capital strength used
     by the Company and investors  based on  shareholders'  equity as defined by
     generally  accepted  accounting  principles in the United States of America
     minus   intangible   assets  and  equity  that  does  not  benefit   common
     shareholders  such as  preferred  equity  and equity  provided  by the U.S.
     Treasury's Troubled Asset Relief Program ("TARP") Capital Purchase Program.
     BOK  Financial  chose  not to  participate  in the  TARP  Capital  Purchase
     Program.  The  Company's  Tier 1  capital  ratios  as  defined  by  banking
     regulations  were 10.86% at December 31, 2009 and 10.56% at  September  30,
     2009.

o    The Company paid a cash dividend of $16.5 million or $0.24 per common share
     during  the fourth  quarter of 2009.  On  January  26,  2010,  the board of
     directors  declared a cash dividend of $0.24 per common share payable on or
     about February 26, 2010 to shareholders of record as of February 12, 2010.

Net Interest Revenue

Net interest revenue totaled $184.5 million for the fourth quarter of 2009, up
$4.0 million over the third quarter of 2009. Net interest margin was 3.64% for
the fourth quarter of 2009 and 3.63% for the third quarter of 2009 and 3.57% for
the fourth quarter of 2008. The increase in net interest margin over the
previous quarter resulted from improved loan yields and lower funding costs. The
yield on average earning assets decreased 12 basis points from the previous
quarter. Loan yields were up 3 basis points. The increased loan yield partially
offset a 34 basis point decrease in the securities portfolio yield. The cost of
interest-bearing liabilities decreased 15 basis points, including a 20 basis
point decrease in the cost of interest-bearing deposits and a 4 basis point
decrease in the cost of other borrowed funds.

Average earning assets increased $450 million during the fourth quarter of 2009,
primarily due to an $876 million increase in average securities, primarily
residential mortgage-backed securities issued by U.S. government agencies.
Average outstanding loans decreased $395 million. Average balances in all major
loan categories were lower compared to the previous quarter.

Average deposits increased $444 million during the fourth quarter of 2009.
Balances in lower-costing transaction accounts continued to increase and
balances in higher-costing time deposits continued to decline. Average
interest-bearing transaction accounts were up $572 million and average demand
deposits were up $274 million. Average time deposit balances decreased $403
million.

Fees and Commission Revenue

Fees and commissions revenue decreased to $115.9 million for the fourth quarter
of 2009 compared to $120.0 million in the third quarter of 2009 primarily due to
a $4.7 million decrease in brokerage and trading revenue. Securities trading
revenue was down $4.3 million from the previous quarter. All other sources of
fees and commissions revenue remained unchanged from the previous quarter.
Mortgage banking revenue increased $206 thousand due to an increase in loan
production volume. Trust revenue increased $177 thousand due to an increase in
the fair value of trust assets. Deposit service charges and fees decreased $963
thousand due to lower commercial account fees and overdraft fees.

Operating Expenses

Total operating expenses were $176.4 million for the fourth quarter of 2009,
down $2.3 million compared to the previous quarter. Excluding changes in the
fair value of mortgage servicing rights, operating expenses totaled $181.7
million, up $6.0 million over the third quarter of 2009. Growth in operating
expenses was primarily due to mortgage banking expenses which include losses on
loans previously sold with recourse, operating costs associated with repossessed
assets and occupancy costs. Losses on mortgage loans sold with recourse were up
$3.3 million over the previous quarter. Net operating costs associated with
repossessed properties increased $1.5 million and occupancy costs increased $1.8
million. Personnel costs were down $4.3 million primarily due to a $3.0 million
reduction in incentive compensation expense. In addition, operating expenses
decreased $8.3 million due to changes in the fair value of mortgage servicing
rights.

Credit Quality

Non-performing assets decreased $5.4 million during the fourth quarter of 2009
to $484 million or 4.24% of outstanding loans and repossessed assets at December
31, 2009. Non-performing assets at December 31, 2009 consisted of non-accruing
loans of $339 million, renegotiated loans of $16 million (including $13 million
of residential mortgage loans guaranteed by U.S. government agencies) and $129
million of real estate and other repossessed assets. Non-accruing loans
decreased $43 million and repossessed assets increased $40 million during the
quarter.

Non-accruing loans totaled $339 million or 3.01% of outstanding loans at
December 31, 2009, compared with $383 million or 3.30% of outstanding loans at
September 30, 2009. Approximately $164 million of non-accruing loans have been
charged-down to the amount management expects to recover. During the fourth
quarter of 2009, $63 million of new non-accruing loans were identified offset by
$26 million in charge-offs, $47 million in foreclosures and repossessions and
$28 million in payments received.

The decrease in non-accruing loans included $21 million from cash and an equity
interest received during the fourth quarter to partially satisfy bankruptcy
claims against SemGroup. Cash received totaled $7 million and the equity
interest was valued at $14 million. BOK Financial continues to hold a $12
million non-accruing loan to the entity created when SemGroup exited bankruptcy.

Non-accruing commercial loans totaled $101 million or 1.63% of total commercial
loans at December 31, 2009. At December 31, 2009, non-accruing commercial loans
are primarily composed of $31 million or 1.71% of total services sector loans,
$23 million or 1.19% of total energy sector loans and $16 million or 3.90% of
total manufacturing sector loans. Non-accruing commercial loans decreased $27
million since September 30, 2009, primarily related to energy sector loans.

Non-accruing commercial real estate loans totaled $205 million or 8.23% of
outstanding commercial real estate loans at December 31, 2009. Non-accruing
commercial real estate loans attributed to our various markets included $73
million or 32% of total commercial real estate loans in Arizona, $52 million or
22% of total commercial real estate loans in Colorado, $31 million or 3.78% of
total commercial real estate loans in Oklahoma, $24 million or 3.26% of total
commercial real estate loans in Texas and $12 million or 9.06% of commercial
real estate loans in Arkansas. Total non-accruing commercial real estate loans
decreased $7.5 million since September 30, 2009. Newly identified non-accruing
commercial real estate loans totaled $46 million, partially offset by $27
million of foreclosures, $15 million of cash payments received and $12 million
of charge-offs.

Non-accruing residential mortgage loans totaled $30 million or 1.67% of
outstanding residential mortgage loans at December 31, 2009. The distribution of
non-accruing residential mortgage loans among our various markets included $15
million or 1.22% of residential mortgage loans in Oklahoma, $9 million or 2.87%
of residential mortgage loans in Texas and $3 million or 4.61% of residential
mortgage loans in Arizona. Non-accruing residential mortgage loans decreased
$8.2 million compared to September 30, 2009. Residential mortgage loans past due
30 to 90 days totaled $20 million, unchanged from September 30, 2009.

The combined allowance for credit losses totaled $306 million or 2.72% of
outstanding loans and 90% of non-accruing loans at December 31, 2009. The
allowance for loan losses was $292 million and the reserve for off-balance sheet
credit losses was $14 million. During the fourth quarter of 2009, the Company
recognized a $48.6 million provision for credit losses. Net losses charged
against the allowance for loan losses totaled $35.0 million or 1.22% annualized
of average outstanding loans. For the full year 2009, the Company recognized a
$196 million provision for credit losses. Net losses charged against the
allowance for loan losses totaled $138 million or 1.14% of average loans.

Real estate and other repossessed assets totaled $129 million at December 31,
2009 consisting of $63 million of 1-4 family residential properties and
residential land development properties, $36 million of developed commercial
real estate properties, $14 million of equity interest received in partial
satisfaction of debts, $8 million of undeveloped land, $5 million of equipment
and $2 million of automobiles. The distribution of real estate owned and other
repossessed assets among various markets included $52 million in Arizona, $23
million in Texas, $10 million in Colorado, $9 million in New Mexico, $23 million
in Oklahoma, $6 million in Kansas City and $6 million in Arkansas. Real estate
and other repossessed assets increased by $40 million during the fourth quarter
due to additions of $53 million partially offset by $7 million in sales and $6
million in write-downs based on updated appraisals.

The Company also has off-balance sheet obligations related to certain community
development residential mortgage loans sold to U.S. government agencies with
recourse. These mortgage loans were underwritten to standards approved by the
agencies, including full documentation and originated under programs available
only for owner-occupied properties. The outstanding principal balance of these
loans totaled $331 million at December 31, 2009. The loans are primarily to
borrowers in our primary market areas, including $233 million in Oklahoma, $36
million in Arkansas, $19 million in New Mexico, $16 million in Kansas City and
$15 million in Texas. At December 31, 2009, approximately 5.22% of these loans
are non-performing and 5.55% were past due 30 to 90 days. A separate reserve for
credit risk of $14 million is available for losses on these loans.

Securities and Derivatives

The fair value of available for sale securities totaled $8.9 billion at December
31, 2009, up $513 million since September 30, 2009. The available for sale
portfolio consisted primarily of residential mortgage-backed securities,
including $7.8 billion fully backed by U.S. government agencies and $792 million
privately issued by publicly owned financial institutions. The portfolio does
not hold any securities backed by sub-prime mortgage loans, collateralized debt
obligations or collateralized loan obligations. The Company holds no debt of
corporate issuers.

The Company continued a strategy to increase holdings of residential
mortgage-backed securities during the fourth quarter. This strategy recognizes
attractive spreads over funding costs on these securities. Credit risk is
controlled by investing in securities fully backed by U.S. government agencies.
Interest rate risk is mitigated by investing in short-duration securities that
would have limited extension exposure from rising interest rates.

The portfolio of available for sale securities had net unrealized gains of $13
million at December 31, 2009 compared to net unrealized gains of $31 million at
September 30, 2009. Net unrealized gains on residential mortgage-backed
securities issued by U.S. government agencies decreased $39 million during the
fourth quarter to $164 million at December 31, 2009. Net unrealized losses on
privately-issued residential mortgage-backed securities decreased $22 million to
$169 million at December 31, 2009.

The amortized cost of privately-issued mortgage-backed securities totaled $961
million at December 31, 2009, down $371 million since September 30 due primarily
to cash received. Approximately $589 million of the privately issued
mortgage-backed securities were rated below investment grade by at least one
nationally-recognized rating agency. The aggregate unrealized losses on
privately-issued mortgage-backed securities rated below investment grade totaled
$129 million at December 31, 2009. Aggregate unrealized losses on these same
securities were $137 million at September 30, 2009. The Company recognized a
$14.5 million other-than-temporary impairment charge against earnings in the
fourth quarter related to these securities due to further declines in projected
cash flows as a result of worsening trends in delinquencies, foreclosures and
housing prices.

Net realized gains on securities totaled $7.3 million for the fourth quarter of
2009, compared with $12.3 million for the third quarter of 2009 and $20.2
million for the fourth quarter of 2008.

The Company recognized $11.7 million of gains on the sale of $776 million of
available for sale securities in the fourth quarter of 2009 and $8.7 million of
net gains on the sale of $719 million of available for sale securities in the
third quarter of 2009. Securities were sold either because they had reached
their maximum potential total return or to mitigate extension exposure from
rising interest rates.

BOK Financial also maintains a portfolio of residential mortgage-backed
securities issued by U.S. government agencies as an economic hedge against
changes in the fair value of mortgage servicing rights. The fair value of
mortgage servicing rights increased $5.3 million and the fair value of mortgage
hedge securities decreased $4.4 million during the fourth quarter of 2009.

The Company has a portfolio of derivative contracts held for customer risk
management programs and internal interest rate risk management programs. At
December 31, 2009, the fair value of all asset contracts totaled $344 million,
net of cash margin held by the Company. The largest net amount due from a single
counterparty, a subsidiary of an international energy company, to these
contracts at December 31 was $84 million. Letters of credit issued by
independent financial institutions offset $70 million of this amount.


Loans, Deposits and Capital

Outstanding loans at December 31, 2009 were $11.3 billion, down $332 million
from September 30, 2009. Loan balances were lower across most sectors of the
loan portfolio and markets due to reduced customer demand in response to current
economic conditions and normal repayment trends. Commercial loans decreased $162
million from September 30, 2009, primarily due to a $182 million decrease in
energy sector loans and a $39 million decrease in manufacturing sector loans,
offset by a $47 million increase in healthcare sector loans and $39 million
increase in service sector loans. Commercial real estate loans decreased $69
million compared to the prior quarter, primarily due to a $90 million decrease
in residential construction and land development loans and a $25 million
decrease in loans secured by office buildings, offset by a $21 million increase
in loans secured by multifamily properties and a $19 million increase in loans
secured by industrial properties. Residential mortgage loans decreased $36
million from the prior quarter primarily due to a $45 million decrease in
permanent mortgage loans offset by a $9 million increase in home equity loans.
Consumer loans decreased $65 million compared to the prior quarter primarily due
to a $62 million decrease in indirect automobile loans related to the previously
announced decision to curtail that business during the first quarter of 2009 in
favor of a customer-focused direct approach to consumer lending.

Total deposits increased $423 million during the third quarter and totaled $15.5
billion at December 31, 2009. Demand and interest-bearing deposits increased
$192 million and $550 million, respectively, offset by a $317 million decrease
in time deposit balances. The Company continued to decrease brokered deposits
and other higher cost certificates of deposit. Among the lines of business,
wealth management and consumer deposits increased $566 million and $64 million,
respectively, offset by a $93 million decrease in commercial deposits.

The Company and each of its subsidiary banks exceeded the regulatory definition
of well capitalized at December 31, 2009. The Company's Tier 1 and total capital
ratios were 10.86% and 14.43%, respectively, at December 31, 2009. The Company's
Tier 1 and total capital ratios were 10.56% and 14.10%, respectively, at
September 30, 2009. In addition the Company's tangible common equity ratio, a
non-GAAP measure, was 7.99% at December 31, 2009 and 7.78% at September 30,
2009. The increase in capital ratios was primarily due to retained earnings
growth.
