(a)  The undersigned Registrant hereby undertakes:

<PAGE>  iii

               (1)  To file during any period in which offers or sales are being
                    made,  a  post-effective   amendment  to  this  Registration
                    Statement to;

                    (i)  include any prospectus  required by Section 10(a)(3) of
                         the Securities Act of 1933;

                    (ii) reflect in the  prospectus  any facts or events arising
                         after the effective date of the registration  statement
                         (or  most  recent  post-effective   amendment  thereof)
                         which,  individually  or in the aggregate,  represent a
                         fundamental  change in the information set forth in the
                         registration statement.  Notwithstanding the foregoing,
                         any  increase  or  decrease  in  volume  of  securities
                         offered  (if  the  total  dollar  value  of  securities
                         offered would not exceed that which was registered) and
                         any deviation from the low or high end of the estimated
                         maximum  offering range may be reflected in the form of
                         prospectus  filed with the Commission  pursuant to Rule
                         424(b) if, in the aggregate,  the changes in volume and

                         Calculation of Registration  Fee table in the effective
                         registration statement; and

                    (iii)include any additional or changed material  information
                         with respect to the plan of distribution not previously
                         disclosed in the registration statement or any material
                         statement; provided, however, that paragraphs (a)(1)(i)
                         and (a)(1)(ii) do not apply if the information required
                         to be included in a  post-effective  amendment by those
                         paragraphs is contained in periodic  reports filed with
                         or  furnished  to  the  Commission  by  the  Registrant
                         pursuant  to  Section  13 or  15(d)  or the  Securities
                         Exchange Act of 1934 that are incorporated by reference
                         in the registration statement.

               (2)  That,  for the purposes of determining  any liability  under
                    the  Securities  Act  of  1933,  each  such   post-effective
                    amendment shall be deemed to be a new registration statement
                    relating to the securities offered therein, and the offering
                    for such  securities  at the time  shall be deemed to be the
                    initial bona fide offering thereof.

               (3)  To  remove  from  registration  by means  of  post-effective
                    amendment  any  of the  securities  being  registered  which
                    remain unsold at the termination of the offering.

(b)  The  undersigned   Registrant  hereby  undertakes  that,  for  purposes  of
     determining  any liability under the Securities Act of 1933, each filing of
     the  Registrant's  annual report  pursuant to Section 13(a) or 15(d) of the
     Securities  Exchange Act of 1934 (and, where applicable,  each filing of an
     employee  benefit  plan's  annual  report  pursuant to Section 15(d) of the
     Securities  Exchange Act of 1934) that is  incorporated by reference in the
     registration  statement shall be deemed to be a new registration  statement
     relating  to the  securities  offered  therein,  and the  offering  of such
     securities  at that  time  shall be  deemed  to be the  initial  bona  fide
     offering thereof.

(c)  Insofar as indemnification for liabilities arising under the Securities Act
     of 1933 may be permitted to directors,  officers and controlling persons of
     the  Registrant  pursuant to the foregoing  provisions,  or otherwise,  the
     Registrant  has been  advised  that in the  opinion of the  Securities  and
     Exchange  Commission  such  indemnification  is  against  public  policy as
     expressed in the Act and is, therefore,  unenforceable. In the event that a
     claim for indemnification  against such liabilities (other than the payment
     by the  Registrant  of expenses  incurred or paid by  director,  officer or
     controlling  person of the  Registrant  in the  successful  defense  of any
     action,  suit or  proceeding)  is  asserted  by such  director,  officer or
     controlling person in connection with the securities being registered,  the
     Registrant  will,  unless in the  opinion of it counsel the matter has been
     settled  by  controlling  precedent,  submit  to  a  court  of  appropriate
     jurisdiction  the question  whether such  indemnification  by it is against
     public  policy as  expressed  in the Act and will be  governed by the final
     adjudication of such issue.

                           BOKF 2003 STOCK OPTION PLAN

SECTION 1.  ESTABLISHMENT, PURPOSE AND EFFECTIVE DATE OF PLAN.

     1.1  Establishment.   BOK  Financial   Corporation  (the  "Corporation"  or
          "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
the right to purchase shares of Common Stock of the Corporation on the terms and
conditions hereafter set forth in this and succeeding sections of the BOKF 2003
Plan:

     2.1  The Common Stock subject to the 2003 Options shall be the Common Stock
          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
          to December 31, 2005.

     2.3  The  2003  Options  owned  by  each  Participant   shall  entitle  the
          Participant,  subject to the terms and conditions  hereof, to purchase
          that number of shares of BOKF

<PAGE>

          Common Stock set forth in one or more Award  Letters  delivered to the
          Participant  from time to time  ("Participant's  2003 Option Shares").
          Each Award  Letter  shall  bear the date on which the Award  Letter is
          issued (the "Award  Date").  The total number of shares of BOKF Common
          Stock subject to 2003 Options shall be 2,000,000.  The maximum  number
          of shares of BOKF Common Stock subject to the 2003 Options that may be
          granted to a Participant during a calendar year period is 100,000.  If
          the  employment of a Participant is terminated for any reason and such
          Participant  has not  exercised  the 2003  Options with respect to any
          shares,  the  Corporation  may award  2003  Options in respect of such
          shares to  existing  Participants  or to  additional  Participants  by
          issuing additional Award Letters before December 31, 2005.

     2.4  The purchase  price of shares subject to the 2003 Options shall be the
          fair market  value for BOKF Common  Stock on NASDAQ on the date of the
          Award Letter (the "Option Price").

     2.5  The 2003  Options may be  exercised in  accordance  with,  and only in
          accordance with, the following schedule:

          2.5.1At any time and from  time to time one  calendar  year  after the
               Award Date and prior to four calendar years after the Award Date,
               with respect to one seventh  (1/7) of the 2003 Option  Shares set
               forth in the Award Letter.

          2.5.2At any time and from time to time two  calendar  years  after the
               Award Date and prior to five calendar years after the Award Date,

               set forth in the Award Letter.

          2.5.5At any time and from time to time five  calendar  years after the
               Award  Date and  prior to eight  calendar  years  after the Award
               Date, with respect to one seventh (1/7) of the 2003 Option Shares
               set forth in the Award Letter.

          2.5.6At any time and from time to time six  calendar  years  after the
               Award Date and prior to nine calendar years after the Award Date,

               Award Date and prior to ten calendar  years after the Award Date,

               forth in the Award Letter.

     2.6  The 2003 Options may be  exercised  only by  delivering  (i) a written
          notice of  exercise  (stating  the fact that  2003  Options  are being

          and (ii)  payment in full of the  purchase  price of the shares  being

          to the  purchase  price  based on the  closing  price  quoted for BOKF
          Common Stock on NASDAQ on the trading day  immediately  preceding  the
          date of exercise, or (iv) a combination of (i), (ii), or (iii).

     2.7  The  Corporation  shall deliver to the  Participant  the  certificates
          representing the shares purchased pursuant to the exercise of the 2003
          Options within thirty (30) days of the date of exercise.

     2.8  BOKF Common Stock acquired  pursuant to the 2003 Options may be resold
          only pursuant to the provisions of Section 4 hereof.

SECTION 3. PROVISIONS  APPLICABLE TO THE 2003 OPTIONS.  The following provisions
shall  apply to the 2003  Options  and all BOKF  Common  Stock  issued  pursuant
thereto.

     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.
<PAGE>

          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

<PAGE>

               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,

<PAGE>

          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.

(a)  The undersigned Registrant hereby undertakes:
iii

               (1)  To file during any period in which offers or sales are being
                    made,  a  post-effective   amendment  to  this  Registration
                    Statement to;

                    (i)  include any prospectus  required by Section 10(a)(3) of
                         the Securities Act of 1933;

                    (ii) reflect in the  prospectus  any facts or events arising
                         after the effective date of the registration  statement
                         (or  most  recent  post-effective   amendment  thereof)
                         which,  individually  or in the aggregate,  represent a
                         fundamental  change in the information set forth in the
                         registration statement.  Notwithstanding the foregoing,
                         any  increase  or  decrease  in  volume  of  securities
                         offered  (if  the  total  dollar  value  of  securities
                         offered would not exceed that which was registered) and
                         any deviation from the low or high end of the estimated
                         maximum  offering range may be reflected in the form of
                         prospectus  filed with the Commission  pursuant to Rule
                         424(b) if, in the aggregate,  the changes in volume and

                         maximum  aggregate  offering  price  set  forth  in the
                         Calculation of Registration  Fee table in the effective
                         registration statement; and

                    (iii)include any additional or changed material  information
                         with respect to the plan of distribution not previously
                         disclosed in the registration statement or any material
                         statement; provided, however, that paragraphs (a)(1)(i)
                         and (a)(1)(ii) do not apply if the information required
                         to be included in a  post-effective  amendment by those
                         paragraphs is contained in periodic  reports filed with
                         or  furnished  to  the  Commission  by  the  Registrant
                         pursuant  to  Section  13 or  15(d)  or the  Securities
                         Exchange Act of 1934 that are incorporated by reference
                         in the registration statement.

               (2)  That,  for the purposes of determining  any liability  under
                    the  Securities  Act  of  1933,  each  such   post-effective
                    amendment shall be deemed to be a new registration statement
                    relating to the securities offered therein, and the offering
                    for such  securities  at the time  shall be deemed to be the
                    initial bona fide offering thereof.

               (3)  To  remove  from  registration  by means  of  post-effective
                    amendment  any  of the  securities  being  registered  which
                    remain unsold at the termination of the offering.

(b)  The  undersigned   Registrant  hereby  undertakes  that,  for  purposes  of
     determining  any liability under the Securities Act of 1933, each filing of
     the  Registrant's  annual report  pursuant to Section 13(a) or 15(d) of the
     Securities  Exchange Act of 1934 (and, where applicable,  each filing of an
     employee  benefit  plan's  annual  report  pursuant to Section 15(d) of the
     Securities  Exchange Act of 1934) that is  incorporated by reference in the
     registration  statement shall be deemed to be a new registration  statement
     relating  to the  securities  offered  therein,  and the  offering  of such
     securities  at that  time  shall be  deemed  to be the  initial  bona  fide
     offering thereof.

(c)  Insofar as indemnification for liabilities arising under the Securities Act
     of 1933 may be permitted to directors,  officers and controlling persons of
     the  Registrant  pursuant to the foregoing  provisions,  or otherwise,  the
     Registrant  has been  advised  that in the  opinion of the  Securities  and
     Exchange  Commission  such  indemnification  is  against  public  policy as
     expressed in the Act and is, therefore,  unenforceable. In the event that a
     claim for indemnification  against such liabilities (other than the payment
     by the  Registrant  of expenses  incurred or paid by  director,  officer or
     controlling  person of the  Registrant  in the  successful  defense  of any
     action,  suit or  proceeding)  is  asserted  by such  director,  officer or
     controlling person in connection with the securities being registered,  the
     Registrant  will,  unless in the  opinion of it counsel the matter has been
     settled  by  controlling  precedent,  submit  to  a  court  of  appropriate
     jurisdiction  the question  whether such  indemnification  by it is against
     public  policy as  expressed  in the Act and will be  governed by the final
     adjudication of such issue.

          "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
the right to purchase shares of Common Stock of the Corporation on the terms and
conditions hereafter set forth in this and succeeding sections of the BOKF 2003

     2.1  The Common Stock subject to the 2003 Options shall be the Common Stock
          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

          that number of shares of BOKF
Common Stock set forth in one or more Award  Letters  delivered to the
          Participant  from time to time  ("Participant's  2003 Option Shares").

     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.
