                 BOK Financial Reports Record Earnings for 2003
Strong Non-Interest Business Lines Contribute to 13th Consecutive Year of Growth

     TULSA, Okla. (Wednesday, Jan. 28, 2004)--BOK Financial Corporation reported
record annual earnings for the 13th consecutive year as strong  performance from
non-interest  lines of business  continued to support  growth.  The  Tulsa-based
financial  services company  reported net income for 2003 of $158.4 million,  or
$2.45 per share,  compared with $147.9 million, or $2.37 per share, in 2002. Net
income has grown each year since the company was founded and  reported its first
annual earnings in 1991.

     Net income for the fourth  quarter of 2003 was $35.3  million,  or 55 cents
per share,  compared with fourth quarter 2002 net earnings of $38.2 million,  or
60 cents per share.

     "Non-interest  business lines continued to play a vital role in our success
during a period of slow  economic  growth  and the lowest  interest  rates in 40
years," said President and CEO Stan Lybarger.  "Although fourth quarter mortgage
banking  revenues  were  adversely  affected  by  the  slowdown  in  refinancing
activity, growth in our other revenue sources resulted in solid performance."

     Fees  and  commission  revenue  for 2003  increased  $49.5  million,  or 19
percent,  compared with last year. All categories of fee income increased,  most
notably brokerage and trading revenue,  which grew 58 percent, and deposit fees,
which rose 21 percent.  This growth  reflected the company's  expanded  presence
through its Little Rock, Arkansas office and new deposit products.

     Strong  revenue  growth  from fees and  commissions  continued  through the
fourth quarter of 2003. Excluding mortgage banking revenue, fees and commissions
grew 23 percent.  Trust fees rose 32 percent  due to growth in trust  assets and
the addition of Colorado  State Bank and Trust,  which was acquired in the third
quarter of 2003. Brokerage and trading revenue grew 25 percent. Revenue from the
company's public finance unit, which is included in other revenue,  totaled $2.8
million  for the fourth  quarter of 2003  compared  with  $439,000  for the same
period of 2002.

     Mortgage  banking  revenue  decreased  50 percent to $7.5  million  for the
fourth  quarter.  Revenue from mortgage loan  production was $2.5 million in the
fourth quarter of 2003 compared with $8.3 million in 2002. Mortgage loans funded
totaled $159 million and $356 million for the fourth  quarters of 2003 and 2002,
respectively. Mortgage servicing revenue was $5.0 million for the fourth quarter
of 2003 compared with $6.6 million in 2002. The outstanding  balance of mortgage
loans  serviced  decreased to $4.4 billion at Dec. 31, 2003,  compared with $5.4
billion at Dec. 31, 2002.

     Net interest revenue for 2003 increased $21.8 million,  or 6 percent.  This
increase  resulted  from a $1.4  billion  increase  in average  earning  assets,
reduced by the  effects of a lower net  interest  margin.  Net  interest  margin
decreased  from 3.70 percent for 2002 to 3.43 percent for 2003 as continued  low
interest  rates reduced the spread  between the yield on earning  assets and the
cost of funds.  Net interest  margin was 3.39 percent for the fourth  quarter of
2003  compared  with  3.55  percent  a year ago and 3.32  percent  for the third
quarter of 2003.

     "Our loan  growth  during the fourth  quarter was the  strongest  in over a
year,"  Lybarger said.  "Increased loan demand and improving net interest margin
are positive signs for the future."

     Growth in fee revenue and net  interest  revenue  was  partially  offset by
lower  gains on  financial  instruments.  Securities  gains  for 2003  were $7.2
million,  compared with $58.7 million in 2002, including net gains on securities
held as an economic hedge of mortgage  servicing  rights of $4.0 million in 2003
and $25.8 million in 2002. Other  securities  sales and  derivatives,  which are
used primarily in the company's interest rate risk management programs, produced
net losses of $5.6  million in 2003,  compared to net gains $38.8  million  last
year.

     The increase in net income for 2003 was aided by a $15.7 million  reduction
in operating expenses. The provision for impairment of mortgage servicing rights
shifted  from a $45.9  million  expense in 2002 to a $22.9  million  recovery in
2003. This shift reflected the effects of changing  interest rates over the past
two years on the value of mortgage servicing rights. Excluding the provision for
mortgage servicing rights,  operating  expenses  increased $53.1 million,  or 14
percent,  due primarily to increased personnel costs.  Personnel costs increased
$35.5 million,  or 19 percent,  including a $14.2 million  increase in incentive
compensation that varies directly with changes in revenue.

     Total  operating  expenses for the fourth  quarter of 2003  increased  $3.3
million, or 3 percent,  compared with last year.  Personnel costs increased $7.5
million or 15 percent.  This increase included $2.4 million from the acquisition
of Colorado  State Bank and Trust and $2.2 million from  incentive  compensation
that is directly based on revenue growth.

     The company also  incurred  $1.1  million of  compensation  costs  directly
associated with a 5 percent workforce  reduction.  The positions were eliminated
to align  staffing  levels  with  business  needs.  Annual  expense  savings are
expected to exceed $9 million beginning in 2004.

     Credit quality remained stable.  Nonperforming assets were $59.9 million or
0.81 percent of outstanding loans at Dec. 31, 2003,  compared with $56.6 million
or 0.84 percent of outstanding  loans at Dec. 31, 2002. Net  charge-offs for the
fourth  quarter of 2003  decreased to $6.3 million from $6.5 million a year ago.
The company  recorded an $8.0  million  provision  for loan losses in the fourth
quarter of 2003  compared  with $10.0  million in 2002.  The  allowance for loan
losses was 1.73 percent of  outstanding  loans and 244 percent of  nonperforming
loans  at  Dec.  31,  2003,   compared   with  1.72  percent  and  233  percent,
respectively, at Dec. 31, 2002.
