           BOK Financial Reports Solid Quarterly, Nine-Month Earnings
            Colorado Acquisition Marks Continued Geographic Expansion

     TULSA,  Okla.  (Wednesday,  October 15,  2003)--BOK  Financial  Corporation
reported  solid third  quarter and  nine-month  results as revenue from fees and
commissions continued to grow.

     Tulsa-based  BOK  Financial  reported  third  quarter  net  income of $38.8
million,  or 60 cents per  share.  Net  income in the third  quarter of 2002 was
$43.5 million, or 70 cents per share, which included $8.1 million from after-tax
gains on securities sales,  less provision for impairment of mortgage  servicing
rights, and mark-to-market gains on derivatives. These net gains were influenced
by declining interest rates at the time.

     Net income  for the first  nine  months of 2003 was up 12 percent to $123.1
million,  or $1.91 per share,  compared with $109.7 million, or $1.77 per share,
for the same period of 2002.

     "Our 2003 third  quarter and  nine-month  results  show that we continue to
perform well despite  pressure on our net interest margin from  historically low
interest  rates," said  President  and CEO Stan  Lybarger.  "Fee  revenues  were
particularly  strong in the  quarter,  growing 24 percent over the same period a
year ago.  During the third  quarter of 2003,  we closed on the  acquisition  of
Colorado State Bank and Trust substantially expanding our presence in the Denver
area."

     BOK Financial  adopted the accounting  provisions of Statement of Financial
Accounting Standards No. 123,  "Accounting for Stock-Based  Compensation" during
the third quarter of 2003.  This newly  adopted  accounting  standard  increased
third quarter operating expenses $1.2 million. Financial statements for previous
periods have been restated as required by this standard to consistently  reflect
this accounting change.

     The growth in non-interest  revenue from fees and commissions of 24 percent
was derived from a number of sources.  Brokerage  and trading  revenue more than
doubled to $11.6  million due  primarily  to  increased  sales to  institutional
customers.  Trust fees and  commissions  rose 22 percent,  revenue  from service
charges and fees on deposit  accounts  grew 15  percent,  and  transaction  card
revenue increased 12 percent.

     Mortgage  banking  revenue was  unchanged as both  quarters  reflected  the
effects of continued low interest  rates.  Revenue from mortgage loan production
was $7.6 million in 2003 compared to $5.5 million in 2002. Mortgage loans funded
totaled $425  million and $264  million in the third  quarters of 2003 and 2002,
respectively. The increase in revenue from loan production was largely offset by
a $1.9 million decrease in servicing fees. The outstanding  principal balance of
mortgage loans serviced decreased to $4.5 billion at Sept. 30, 2003, compared to
$5.8 billion at Sept. 30, 2002.

     For the third  quarter,  the company  recovered  $16.2  million  previously
accrued for impairment of mortgage  servicing rights (MSR). This recovery offset
net losses of $16.6 million in sales of securities and derivatives,  including a
net loss of $2.8  million  on  sales of  securities  held as an  economic  hedge
against impairment of MSR, a $4.6 million  mark-to-market  loss on interest rate
derivatives  and a $9.2  million  net loss on sales  of  other  securities.  The
company  continues to reposition  its  securities  portfolio by  reinvesting  in
instruments with less extension risk.

     Net  interest  revenue  rose 4 percent  during  the third  quarter to $96.2
million,  compared  with $92.6  million a year ago, as growth in earning  assets
partially offset a lower net interest  margin.  Average earning assets increased
$1.4 billion to $11.6  billion while the net interest  margin  decreased to 3.32
percent.  Declining  interest rates combined with a change in the mix of earning
assets  decreased the yield on earning  assets by 94 basis  points.  The cost of
interest-bearing deposits and other borrowed funds decreased 68 basis points.

     Total assets rose to $13.1 billion at Sept.  30, 2003,  compared with $11.9
billion a year  earlier.  Total loans were $7.3  billion,  up $696  million from
Sept. 30, 2002.  Commercial and commercial  real estate loans were up 10 percent
and 12 percent, respectively, compared to last year.

     Credit  quality  remains very stable.  Non-performing  assets to period end
loans were 0.82 percent and  annualized  net  charge-offs  to average loans were
0.36 percent, compared with 0.93 percent and 0.31 percent respectively,  for the
third quarter of 2002.  The provision  for loan losses  remained  stable at $8.2
million compared with $8.0 million a year earlier. The allowance for loan losses
was 1.77 percent of outstanding loans and 250 percent of nonperforming  loans at
Sept.  30, 2003,  compared with 1.72 percent and 208 percent,  respectively,  at
Sept. 30, 2002.

     Deposits were $8.9 billion at Sept.  30, 2003, up 19 percent from the third
quarter of 2002.  Interest-bearing  transaction accounts contributed most of the
growth.

     Total  operating  expenses  decreased  $33 million due  primarily  to a $45
million reduction in the provision for impairment of MSRs. Excluding this change
in provision, operating expenses rose 13 percent over the third quarter of 2002.
Personnel  expenses increased $10.9 million,  or 24 percent,  due primarily to a
$4.2 million  increase in commissions that are directly based on revenue growth.
Additionally,   the  company   recorded  a  $1.7  million  charge  for  deferred
compensation.  Data processing and communications fees grew $1.9 million, partly
from the growth in  transaction  volumes.  Mortgage  banking costs declined $3.4
million as rising interest rates decreased MSR amortization expense.
