          "BOKF"),  an Oklahoma  corporation,  hereby establishes the "BOKF 2003
          Stock Option Plan" (the "BOKF 2003 Plan") for designated  employees of
          the Corporation and of various direct and indirect subsidiaries of the
          Corporation (collectively, "BOKF").

     1.2  Purpose. The purpose of the BOKF 2003 Plan is to advance the interests
          of  the   Corporation   (i)  by  encouraging  and  providing  for  the
          acquisition of an equity  interest in the Corporation by key employees
          of BOKF and (ii) by enabling  BOKF to attract and retain the  services
          of key employees  whose  judgment,  interest,  and special  effort are
          desired for the successful conduct of operations.

     1.3  Effective  Date. The BOKF 2003 Plan shall become  effective on January
          1, 2003 (or on such later date as a registration  statement in respect
          of the BOKF 2003 Plan on Securities and Exchange  Commission  Form S-8
          shall become effective).

SECTION 2. THE 2003 OPTIONS. The options ("2003 Options") established hereby are

          of the  Corporation,  par  value  $0.00006  per  share  ("BOKF  Common
          Stock").

     2.2  The owners of the 2003  Options  shall be those  employees  (hereafter
          called a "Participant")  to whom a letter of award ("Award Letter") is
          hereafter delivered by the Independent  Compensation  Committee of the
          Corporation. The Corporation may issue Award Letters at any time prior

     3.1  Non-Transferability.  The 2003  Options may not be sold,  transferred,
          pledged,  assigned, or otherwise alienated or hypothecated,  otherwise
          than by will or by the laws of descent and distribution.

     3.2  Termination  of  2003  Options  Upon   Termination  of  Employment  of
          Participant.  If the  employment  of the  Participant  by  BOKF  shall
          terminate  for any reason  including  death,  disability,  retirement,
          resignation  or  involuntary  termination  (whether  such  involuntary
          termination is with or without cause),  the Participant's 2003 Options
          shall automatically terminate, to the extent not previously exercised,
          provided:

          3.2.1The Chairman of the Board and the Chief Executive Officer may, in
               their  sole  discretion   (which   discretion  may  be  exercised
               arbitrarily) subject to approval of the Board of Directors of the
               Corporation,  extend the  termination of the  Participant's  2003
               Options in special circumstances.

          3.2.2In the event of the termination of employment of a participant by
               reason of death or disability,  the Participant (or, in the event
               of death,  the personal  representative  of the  Participant) may
               purchase,  any of  Participant's  2003  Option  Shares  which the
               Participant had the right to purchase  immediately  preceding the
               date of the  Participant's  termination of employment  within the
               period  of  time  such  Participant  could  have,  but  for  such
               termination, purchased such 2003 Option Shares.



          3.2.3In  the  event  a  Participant's   employment  is   involuntarily
               terminated by BOKF without cause  (determined in accordance  with
               Section 3.2.5) and such involuntary  termination without cause is
               within  one year of a Change of  Control  (as  defined in Section
               3.2.4), the Participant may purchase,  within 90 days of the date
               of  the   Participant's   termination  of   employment,   all  of
               Participant's  2003 Option  Shares (to the extent not  previously
               purchased).

          3.2.4A Change of Control shall be deemed to have occurred if, and only
               if:

               3.2.4.1 George B. Kaiser,  affiliates of George B. Kaiser, and/or
                    members of the family of George B. Kaiser collectively cease
                    to own more shares of the voting  capital stock of BOKF than
                    any other  shareholder (or group of  shareholders  acting in
                    concert  to  control  BOKF to the  exclusion  of  George  B.
                    Kaiser,  affiliates  of George B. Kaiser,  or members of the
                    family of George B. Kaiser); or,

               3.2.4.2 BOKF  shall  cease  to own more  than  50% of the  voting
                    capital stock of Bank of Oklahoma, National Association.





          3.2.5A Participant  shall be deemed to have been  terminated for cause
               if the  Board  of  Directors  of BOKF  determines  (in  its  sole
               discretion  provided only that such  discretion is exercised with
               honesty in fact) that the Participant was terminated by reason of
               (i) any failure to substantially perform Participant's employment
               obligations   to  BOKF  in  a  satisfactory   manner,   (ii)  any
               intentional  act materially  injurious to BOKF,  (iii) any act of
               moral turpitude,  (iv) any material  dishonest or fraudulent act,
               or  (v)  any  refusal  to  obey  orders  or  instructions  of the
               Participant's appropriate supervisors or seniors.

          3.2.6A  Participant  shall be deemed  employed  by BOKF so long as and
               only  so  long  as  the  employee  is in  the  employment  of BOK
               Financial  Corporation or a direct or indirect  subsidiary of BOK
               Financial  Corporation in which BOK Financial  Corporation  owns,
               directly or  indirectly,  more shares of the voting capital stock
               than any other  shareholder (or group of  shareholders  acting in
               concert to control such subsidiary to the exclusion of BOKF).

     3.3  Adjustments.  If there are any  changes in the  capitalization  of the
          Corporation  affecting the number or kind (after the recapitalization)
          of issued  and  outstanding  shares  of BOKF  Common  Stock  (existing
          immediately  prior to the  change  in  capitalization),  whether  such
          changes have been occasioned by reorganization, combination of shares,
          declaration of stock  dividends,  stock splits,  reverse stock splits,
          reclassification  or  recapitalization  of such  stock,  the merger or
          consolidation of the Corporation with some other  corporation or other
          similar  transaction,  then the number and kind of shares then subject
          to the  2003  Options  and the  price  to be paid  therefor,  shall be
          appropriately adjusted by the Corporation;  provided, however, that in
          no event shall any such  adjustment  result in the  Corporation  being
          required to sell or issue a fractional share of stock.



     3.4  Waiver of Shareholder Rights. The Participant or other person entitled
          to exercise 2003 Options  shall have no rights as a  stockholder  with
          respect to any shares  subject  thereto until the  Participant or such
          person shall have exercised the 2003 Options and shall thereafter have
          become the holder of record of such shares and no  adjustment  (except
          such  adjustments  as may be effected  pursuant to the  provisions  of
          Section 3.3 hereof)  shall be made for dividends or  distributions  of
          rights in respect of such shares for which the record date is prior to
          the date on which the Participant or such person so becomes the holder
          of record.
