                             UNDERWRITING AGREEMENT

                              ______________, 199_



[NAME]
as Representative of the several Underwriters
[ADDRESS]

Ladies and Gentlemen:

         BOK Financial  Corporation,  an Oklahoma  corporation  (the "Company"),
confirms its agreement with  [Name]("[Name]") and each of the other Underwriters
named in Schedule A hereto  (collectively,  the "Underwriters," which term shall
also include any underwriter  substituted as hereinafter  provided in Section 10
hereof),  for whom [Name] is acting as  representative  (in such  capacity,  the
"Representative"),  with  respect to the  purchase by the  Underwriters,  acting
severally and not jointly,  of $______  principal amount of the [Title of Senior
Debt Securities] (the "Securities") of the Company, to be issued pursuant to the
provisions of an Indenture, dated as of ______________,  199_ (the "Indenture"),
between the Company and ____________, as Trustee (the "Trustee").

         The Company understands that the Underwriters  propose to make a public
offering of the Securities as soon as the  Representative  deems advisable after
this Agreement has been executed and delivered.
                  
         The Company has filed with the Securities and Exchange  Commission (the
"Commission") a registration statement on Form S-3 (No.  333-_________) covering
the  registration  of Senior  Debt  Securities  of the  Company,  including  the
Securities,  from time to time in accordance  with Rule 415 under the Securities
Act of 1933,  as amended (the "1933  Act"),  including  the related  preliminary
prospectus  or  prospectuses.  Promptly  after  execution  and  delivery of this
Agreement,  the  Company  will  either  (i)  prepare  and file a  prospectus  in
accordance  with the  provisions  of Rule  430A  ("Rule  430A") of the rules and
regulations  of the Commission  under the 1933 Act (the "1933 Act  Regulations")
and paragraph  (b) of Rule 424 ("Rule  424(b)") of the 1933 Act  Regulations  or
(ii) if the Company  has elected to rely upon Rule 434 ("Rule  434") of the 1933
Act  Regulations,  prepare and file a term sheet (a "Term  Sheet") in accordance
with the  provisions of Rule 434 and Rule 424(b).  The  information  included in
such prospectus or in such Term Sheet, as the case may be, that was omitted from
such  registration  statement at the time it became effective but that is deemed
to be part of such  registration  statement at the time it became  effective (a)
pursuant to paragraph (b) of Rule 430A is referred to as "Rule 430A Information"
or (b)  pursuant  to  paragraph  (d) of Rule 434 is  referred  to as  "Rule  434
Information."  Each prospectus used before such  registration  statement  became
effective,  and any  prospectus  that  omitted,  as  applicable,  the Rule  430A
Information or the Rule 434 Information,  that was used after such effectiveness
and prior to the  execution and delivery of this  Agreement,  is herein called a
"preliminary  prospectus." 


                                                       
2


Such registration statement,  including the exhibits thereto, schedules thereto,
if any, and the documents  incorporated by reference therein pursuant to Item 12
of Form S-3 under the 1933 Act, at the time it became  effective  and  including
the Rule 430A Information and the Rule 434 Information, as applicable, is herein
called the "Registration  Statement." Any registration  statement filed pursuant
to Rule 462(b) of the 1933 Act  Regulations  is herein  referred to as the "Rule
462(b)  Registration  Statement,"  and after such filing the term  "Registration
Statement"  shall  include the Rule  462(b)  Registration  Statement.  The final
prospectus,  including the documents  incorporated by reference therein pursuant
to Item 12 of Form S-3 under the 1933 Act,  in the form first  furnished  to the
Underwriters  for use in  connection  with the  offering of the  Securities,  is
herein called the  "Prospectus." If Rule 434 is relied on, the term "Prospectus"
shall refer to the preliminary prospectus dated ___, 199_ together with the Term
Sheet,  and all references in this Agreement to the date of the Prospectus shall
mean the date of the Term Sheet.

         All references in this Agreement to financial  statements and schedules
and other  information  which is  "contained,"  "included"  or  "stated"  in the
Registration  Statement,  any preliminary prospectus or the Prospectus (or other
references  of like  import)  shall  be  deemed  to mean  and  include  all such
financial  statements and schedules and other  information which is incorporated
by reference in the Registration  Statement,  any preliminary  prospectus or the
Prospectus,  as the  case  may be;  and all  references  in  this  Agreement  to
amendments  or  supplements  to  the  Registration  Statement,  any  preliminary
prospectus or the  Prospectus  shall be deemed to mean and include the filing of
any document  under the  Securities  Exchange Act of 1934, as amended (the "1934
Act"),  which is incorporated by reference in the Registration  Statement,  such
preliminary prospectus or the Prospectus, as the case may be.

         SECTION 1.  Representations and Warranties.

         (a)  Representations  and  Warranties  by  the  Company.   The  Company
represents and warrants to each  Underwriter as of the date hereof and as of the
Closing Time referred to in Section 2(b) hereof, as follows:

                  (i) Compliance  with  Registration  Requirements.  The Company
                  meets the requirements for use of Form S-3 under the 1933 Act.
                  Each  of  the  Registration  Statement  and  any  Rule  462(b)
                  Registration  Statement  has become  effective  under the 1933
                  Act;  no  stop  order  suspending  the  effectiveness  of  the
                  Registration   Statement  or  any  Rule  462(b)   Registration
                  Statement   has  been  issued   under  the  1933  Act  and  no
                  proceedings  for that  purpose  have  been  instituted  or are
                  pending or, to the knowledge of the Company,  are contemplated
                  by  the  Commission  and  any  request  on  the  part  of  the
                  Commission for additional information has been complied with.

                  At the respective times the Registration  Statement,  any Rule
                  462(b)   Registration   Statement   and   any   post-effective
                  amendments  thereto became  effective and at the Closing Time,
                  the  Registration  Statement,  the  Rule  462(b)  Registration
                  Statement and any amendments and supplements  thereto complied
                  and will comply in all material respects with the requirements
                  of the 1933 Act and the 1933 Act  Regulations  and did not and
                  will not  contain an untrue  statement  of a material  fact or
                  omit to state a material fact required to be stated therein or
                  necessary  to make  the  statements  therein  not  misleading.
                  Neither  the  Prospectus  nor any  amendments  or  supplements
                  thereto,  at the time the  Prospectus or any such amendment or
                  supplement was filed and at the Closing Time, included or will
                  include an untrue  statement of a material  fact or omitted or
                  will omit to state a material fact  necessary in order to make
                  the  statements  therein,  in the  light of the  circumstances
                  under  which they were made,  not  misleading.  If Rule 434 is
                  used,  the Company will comply with the  requirements  of Rule
                  434. The  representations  and  warranties in this  subsection
                  shall not apply to (i)  statements  in or  omissions  from the
                  Registration  Statement,  any post- effective amendment to the
                  Registration  Statement,  the  Prospectus  or any amendment or
                  supplement  to the  Prospectus  made in  reliance  upon and in
                  conformity  with  information  furnished  to  the  Company  in
                  writing by any Underwriter through [Name] expressly for use in
                  the  Registration  Statement,   the  Prospectus  or  any  such
                  amendment or supplement or (ii) that part of the  Registration
                  Statement that constitutes the Statement of Eligibility  (Form
                  T-1) under the Trust  Indenture  Act of 1939,  as amended (the
                  "Trust Indenture Act") of the Trustee.

                  Each  preliminary  prospectus and the prospectus filed as part
                  of the  Registration  Statement as originally filed or as part
                  of any amendment thereto,  or filed pursuant to Rule 424 under
                  the 1933 Act,  complied when so filed in all material respects
                  with the 1933 Act and the 1933 Act Regulations.

                  deemed to be  incorporated  by reference  in the  Registration
                  Statement  and  the  Prospectus,  at the  time  they  were  or
                  hereafter  are filed with the  Commission,  complied  and will
                  comply in all material  respects with the  requirements of the
                  1934  Act and the  rules  and  regulations  of the  Commission
                  thereunder  (the  "1934  Act  Regulations"),  and,  when  read
                  together with the other information in the Prospectus,  at the
                  time the Registration Statement became effective,  at the time
                  the Prospectus was issued and at the Closing Time, did not and
                  will not  contain an untrue  statement  of a material  fact or
                  omit to state a material  fact  necessary in order to make the
                  statements  therein, in light of the circumstances under which
                  such statements were made, not misleading.

                  (iii) Independent  Accountants.  The accountants who certified
                  the financial  statements and supporting schedules included in
                  the Registration  Statement are independent public accountants
                  as required by the 1933 Act and the 1933 Act Regulations.

                  (iv)  Financial  Statements.  The  consolidated  statements of
                  financial  condition,   consolidated   statements  of  income,
                  consolidated statements of changes in stockholders' equity and
                  consolidated   statements  of  cash  flows   included  in  the
                  Registration  Statement and the Prospectus,  together with the
                  related  schedules  and notes  (the  "Financial  Statements"),
                  present  fairly  in all  material  respects  the  consolidated
                  financial   position,   results  of  operations,   changes  in
                  stockholders'  equity  and cash flows of the  Company  and its
                  consolidated  subsidiaries at the dates indicated and, for the
                  periods specified,  as the case may be, subject in the case of
                  unaudited  balance  sheets and  statements to normal  year-end
                  audit  adjustments;   said  Financial   Statements  have  been
                  prepared in  conformity  with  generally  accepted  accounting
                  principles  ("GAAP")  applied on a consistent basis throughout
                  the periods involved,  except as may be noted therein, subject
                  in the case of  unaudited  balance  sheets and  statements  to
                  normal year-end audit adjustments and the limited scope of the
                  notes thereto.

                  (v)  No  Material  Adverse  Change  in  Business.   Since  the
                  respective  dates  as of  which  information  is  given in the
                  Registration Statement and the Prospectus, except as otherwise
                  stated therein, (A) there has been no material adverse change,
                  or  development   involving  a  prospective  material  adverse
                  change,  in the financial  condition,  results of operation or
                  stockholders'  equity  of the  Company  and  its  subsidiaries
                  considered  as one  enterprise,  whether or not arising in the
                  ordinary course of business (a "Material Adverse Effect"), (B)
                  there have been no transactions entered into by the Company or
                  any of its  subsidiaries,  other  than  those in the  ordinary
                  course of  business,  which are  material  with respect to the
                  Company and its subsidiaries considered as one enterprise, and
                  (C) there has been no  dividend  or  distribution  of any kind
                  declared,  paid or made by the  Company  on any  class  of its
                  capital stock.

                  (vi) Good  Standing of the Company.  The Company has been duly
                  organized  and is validly  existing as a  corporation  in good
                  standing  under  the  laws of the  State of  Delaware  and has
                  corporate  power and  authority to own,  lease and operate its
                  properties  and  to  conduct  its  business  in  all  material
                  respects as described in the  Prospectus and to enter into and
                  perform its obligations under this Agreement;  and the Company
                  is  duly  qualified  as  a  foreign  corporation  to  transact
                  business and is in good standing in each other jurisdiction in
                  which such qualification is required, whether by reason of the
                  ownership  or leasing of property or the conduct of  business,
                  except  where  the  failure  so to  qualify  or to be in  good
                  standing would not result in a Material Adverse Effect.

                  (vii) Good  Standing of  Subsidiaries.  The Bank of  Oklahoma,
                  National Association, Bank of Texas, National Association, and
                  Bank of Arkansas, National Association (the "Banks") have been
                  duly  organized and are validly  existing as national  banking
                  associations;  the Banks'  deposit  accounts are insured up to
                  applicable   limits   by   the   Federal   Deposit   Insurance
                  Corporation;   and  no  proceeding  for  the   termination  or
                  revocation  of such  insurance is pending or, to the knowledge
                  of the Company or the Banks,  threatened.  The Banks and BOSC,

                  applicable  bankruptcy,  insolvency or similar laws  affecting

                  (collectively,  "Agreements and Instruments")  except for such

                  Effect),  nor will such action  result in any violation of the

                  suppliers, manufacturers,  customers or contractors, which, in
                  either  case,  may  reasonably  be  expected  to  result  in a

                  to  comply  would  not,  singly  or in the  aggregate,  have a

                  Governmental Licenses to be in full force and effect would not
                  have a Material  Adverse  Effect;  and neither the Company nor
                  any of its subsidiaries has received any notice of proceedings
                  relating  to  the  revocation  or  modification  of  any  such

                  subsidiary  has any notice of any  material  claim of any sort
                  that has been asserted by anyone  adverse to the rights of the
                  Company or any subsidiary under any of the leases or subleases
                  mentioned above, or affecting or questioning the rights of the
                  Company or such subsidiary to the continued  possession of the
                  leased or subleased premises under any such lease or sublease.

make every  reasonable  effort to prevent the issuance of any stop order and, if
any stop order is issued, to obtain the lifting thereof at the earliest possible
moment.

                                                       

10


         (b) Filing of  Amendments.  The  Company  will give the  Representative
notice of its  intention to file or prepare any  amendment  to the  Registration
Statement  (including  any  filing  under  Rule  462(b)),  any Term Sheet or any
amendment,  supplement  or  revision  to either the  prospectus  included in the
Registration  Statement at the time it became  effective  or to the  Prospectus,
whether  pursuant to the 1933 Act, the 1934 Act or  otherwise,  will furnish the
Representative  with copies of any such  documents a  reasonable  amount of time
prior to such  proposed  filing or use, as the case may be, and will not file or
use  any  such  document  to  which  the   Representative  or  counsel  for  the
Underwriters shall object.

         (c) Delivery of Registration  Statements.  The Company has furnished or
will deliver to the  Representative  and counsel for the  Underwriters,  without
charge,  signed copies of the Registration  Statement as originally filed and of
each amendment  thereto  (including  exhibits filed therewith or incorporated by
reference  therein and documents  incorporated  or deemed to be  incorporated by
reference  therein)  and  signed  copies of all  consents  and  certificates  of
experts,  and  will  also  deliver  to the  Representative,  without  charge,  a
conformed  copy of the  Registration  Statement as originally  filed and of each
amendment thereto (without exhibits) for each of the Underwriters.

         (d)  Delivery  of  Prospectuses.  The  Company  has  delivered  to each
Underwriter,  without charge,  as many copies of each preliminary  prospectus as
such Underwriter  reasonably  requested,  and the Company hereby consents to the
use of such copies for  purposes  permitted  by the 1933 Act.  The Company  will
furnish  to each  Underwriter,  without  charge,  during  the  period  when  the
Prospectus is required to be delivered  under the 1933 Act or the 1934 Act, such
number  of  copies  of the  Prospectus  (as  amended  or  supplemented)  as such
Underwriter may reasonably request.

         (e) Continued  Compliance with Securities Laws. The Company will comply
with the 1933 Act and the 1933 Act Regulations and the 1934 Act and the 1934 Act
Regulations to the extent necessary to permit the completion of the distribution
of the Securities as contemplated in this Agreement and in the Prospectus. If at
any time  when a  prospectus  is  required  by the 1933 Act to be  delivered  in
connection  with sales of the  Securities,  any event shall  occur or  condition
shall  exist  as a  result  of  which it is  necessary,  in the  opinion  of the
Underwriters  or the  Company,  based  upon  advice  of  counsel,  to amend  the
Registration  Statement or amend or supplement  the Prospectus in order that the
Prospectus  will not include any untrue  statement of a material fact or omit to
state a material fact necessary in order to make the statements  therein, in the
light of the  circumstances  under which they were made when such  Prospectus is
delivered,  not misleading,  or if it shall be necessary, in the opinion of such
party,  based  upon  the  advice  of  counsel,  at any such  time to  amend  the
Registration  Statement or amend or supplement the Prospectus in order to comply
with the requirements of the 1933 Act or the 1933 Act  Regulations,  the Company
will  promptly  prepare and file with the  Commission,  subject to Section 3(b),
such  amendment or supplement  as may be necessary to correct such  statement or
omission or to make the  Registration  Statement or the  Prospectus  comply with
such requirements,  and the Company will furnish to the Underwriters such number
of copies of such  amendment or supplement as the  Underwriters  may  reasonably
request.

                                                       

11


         (f) Blue Sky Qualifications.  The Company will use its best efforts, in
cooperation  with the  Underwriters,  to qualify the Securities for offering and
sale under the applicable securities laws of such states and other jurisdictions
as the  Representative  may  designate and to maintain  such  qualifications  in
effect  for  as  long  as may be  necessary  to  complete  the  distribution  of
Securities  provided,  however,  that the Company shall not be obligated to file
any general consent to service of process or to qualify as a foreign corporation
or as a dealer in securities in any jurisdiction in which it is not so qualified
or  to  subject  itself  to  taxation  in  respect  of  doing  business  in  any
jurisdiction in which it is not otherwise so subject.

         (g) Rule 158. The Company will timely file such reports pursuant to the
1934 Act as are necessary in order to make  generally  available to its security
holders as soon as practicable an earnings statement for the purposes of, and to
provide the benefits contemplated by, the last paragraph of Section 11(a) of the
1933 Act.

         (h) Restriction on Sale of Securities. During a period beginning on the
date hereof and  continuing to and including the Closing Time,  the Company will
not, without the prior written consent of [Name], directly or indirectly, offer,
pledge,  sell,  contract  to sell,  sell any  option or  contract  to  purchase,
purchase any option or contract to sell,  grant any option,  right or warrant to
purchase  or  otherwise  transfer  or  dispose  of any  Senior  Debt  Securities
substantially  similar to the  Securities,  except that the  foregoing  sentence
shall not apply to (A) the  Securities to be sold  hereunder and (B)  commercial
paper issued in the ordinary course of business.

         (i)  Reporting  Requirements.  The Company,  during the period when the
Prospectus is required to be delivered  under the 1933 Act or the 1934 Act, will
file all documents required to be filed with the Commission pursuant to the 1934
Act  within  the  time  periods  required  by the  1934  Act  and the  1934  Act
Regulations  and the Company will cause the Bank to file all documents  required
to be filed with any  supervisory,  regulatory,  administrative  or governmental
agency,  body or  authority,  whether  pursuant to the 1934 Act and the 1934 Act
Regulations  or  otherwise  (except  reports  to any bank or  thrift  regulatory
agencies prepared on a confidential basis), except when the failure to file such
documents could not reasonably be expected to result, directly or indirectly, in
a Material Adverse Effect.

         SECTION 4.  Payment of Expenses.

         (a)  Expenses.  The  Company  covenants  and  agrees  with the  several
Underwriters  that (a) the Company will pay the following  expenses  incident to
this Agreement:  (i) the  preparation,  printing and filing of the  Registration
Statement  (including financial statements and exhibits) as originally filed and
of each amendment  thereto,  (ii) the preparation,  printing and delivery to the
Underwriters of this Agreement,  any Agreement among Underwriters and such other

delivery of the  certificates for the Securities to the  Underwriters,  (iv) the
fees and disbursements of the Company's counsel, accountants and other advisors,
(v) the qualification of the Securities under securities laws in accordance with
the provisions of Section 3(f) hereof,  including filing fees and the reasonable
fees and  disbursements of counsel for the Underwriters in connection  therewith
and in connection with the preparation of the Blue Sky Survey and any supplement
thereto,  (vi) the printing and delivery to the  Underwriters  of copies of each
preliminary prospectus, any Term Sheets and of the Prospectus and any amendments
or  supplements  thereto,  (vii) the fees and expenses of any transfer  agent or
registrar  for the  Securities,  (viii) the  filing  fees  incident  to, and the
reasonable fees and  disbursements  of counsel to the Underwriters in connection
with, the review by the NASD of the terms of the sale of the Securities and (ix)
any fees payable in connection with the rating of the Securities.

                                                       
12

         (b)  Termination  of Agreement.  If this Agreement is terminated by the
Representative  in accordance  with the provisions of Section 5, Section 9(a)(i)
or Section 11 hereof,  the Company shall reimburse the  Underwriters  for all of
their  reasonable  out-of-pocket  expenses,  including the  reasonable  fees and
disbursements of counsel for the Underwriters.

         SECTION 5. Conditions of Underwriters' Obligations.  The obligations of
the  several  Underwriters  hereunder  are  subject to the  accuracy,  as of the
Closing Time, of the  representations and warranties of the Company contained in
Section  1 hereof  or in  certificates  of any  officer  of the  Company  or any
subsidiary of the Company  delivered  pursuant to the provisions  hereof, to the
performance by the Company of its covenants and other  obligations  hereunder to
be  performed  at or prior to the Closing  Time,  and to the  following  further
conditions:

         (a)   Effectiveness   of  Registration   Statement.   The  Registration
Statement,   including  any  Rule  462(b)  Registration  Statement,  has  become
effective and at the Closing Time no stop order suspending the  effectiveness of
the  Registration  Statement  shall  have  been  issued  under  the  1933 Act or
proceedings therefor initiated or threatened by the Commission,  and any request
on the  part of the  Commission  for  additional  information  shall  have  been
complied with to the reasonable  satisfaction of counsel to the Underwriters.  A
prospectus  containing the Rule 430A Information  shall have been filed with the
Commission  in  accordance  with  Rule  424(b)  (or a  post-effective  amendment
providing  such  information  shall have been filed and  declared  effective  in
accordance with the requirements of Rule 430A) or, if the Company has elected to
rely upon Rule 434, a Term Sheet  shall have been filed with the  Commission  in
accordance with Rule 424(b).

         (b) Opinion of Counsel for Company. At Closing Time, the Representative
shall have received the favorable opinion, dated as of Closing Time, of Frederic
Dorwart,  Lawyers, General Counsel for the Company, in each instance in form and
substance reasonably satisfactory to counsel for the Underwriters,  collectively
to the effect set forth in Exhibit A hereto.

         (c)  Opinion  of  Counsel  for  Underwriters.   At  Closing  Time,  the
Representative  shall have received the favorable  opinion,  dated as of Closing
Time, of [Name],  counsel for the Underwriters,  with respect to such matters as
they may reasonably request. In giving such opinion such counsel may rely, as to
all  matters  governed  by the laws of  jurisdictions  other than the law of the
State of New  York,  the  federal  law of the  United  States,  and the  General
Corporation  Law  of the  State  of  Delaware,  upon  the  opinions  of  counsel
satisfactory to the Representative. Such counsel may also state that, insofar as
such opinion involves factual matters, they have relied, to the extent they deem
proper,  upon  certificates of officers of the Company and its  subsidiaries and
certificates of public officials.

                                                       

13


         (d) Officers' Certificate.  At Closing Time, there shall not have been,
since the date hereof or since the respective  dates as of which  information is
given in the Prospectus, any material adverse change, or development involving a
prospective  material  adverse change,  in the financial  condition,  results of
operations  or  stockholders'   equity  of  the  Company  and  its  subsidiaries
considered as one  enterprise,  whether or not arising in the ordinary course of
business, and the Representative shall have received a certificate signed by the
President or a Vice President of the Company and by the chief financial or chief
accounting officer of the Company,  dated as of Closing Time, to the effect that
(i) there has been no such material adverse change, (ii) the representations and
warranties  in Section  1(a) hereof are true and correct with the same force and
effect as though expressly made at and as of Closing Time, (iii) the Company has
complied with all  agreements  and  satisfied  all  conditions on its part to be
performed  or  satisfied  at or prior to  Closing  Time,  and (iv) no stop order
suspending the  effectiveness of the Registration  Statement has been issued and
no  proceedings  for that  purpose  have been  instituted  or are pending or are
contemplated by the Commission.

         (e) Accountant's  Comfort Letter.  At the time of the execution of this
Agreement,  the  Representative  shall  have  received  from Ernst & Young LLP a
letter   dated  such  date,   in  form  and   substance   satisfactory   to  the
Representative,  together  with signed or  reproduced  copies of such letter for
each of the other  Underwriters,  containing  statements and  information of the
type ordinarily included in accountants'  "comfort letters" to underwriters with
respect to the financial statements and certain financial  information contained
in the Registration Statement and the Prospectus.

         (f) Bring-down  Comfort  Letter.  At Closing Time,  the  Representative
shall have received from Ernst and Young LLP a letter, dated as of Closing Time,
to the effect that it  reaffirms  the  statements  made in the letter  furnished
pursuant to  subsection  (e) of this  Section,  except that the  specified  date
referred to shall be a date not more than three  business  days prior to Closing
Time.

         (g) No  Objection.  The NASD shall not have raised any  objection  with
respect  to the  fairness  and  reasonableness  of the  underwriting  terms  and
arrangements.

         (h)  Additional  Documents.  At  the  Closing  Time,  counsel  for  the
Underwriters  shall have been furnished with such documents and opinions as they
may  reasonably  require  for the  purpose  of  enabling  them to pass  upon the
issuance  and sale of the  Securities  as  herein  contemplated,  or in order to
evidence  the  accuracy  of any of the  representations  or  warranties,  or the
fulfillment of any of the  conditions,  herein  contained;  and all  proceedings
taken by the Company in connection  with the issuance and sale of the Securities
as herein contemplated shall be reasonably satisfactory in form and substance to
the Representative and counsel for the Underwriters.

         (j)  Termination  of  Agreement.  If any  condition  specified  in this
Section shall not have been fulfilled when and as required to be fulfilled, this
Agreement may be terminated  by the  Representative  by notice to the Company at
any time at or prior to  Closing  Time,  and such  termination  shall be without
liability of any party to any other party,  except as provided in Section 4, and
except that Sections 1, 6, 7 and 8 shall survive any such termination and remain
in full force and effect.

                                                       

14


         SECTION 6.  Indemnification.

         (a) Indemnification by the Company. The Company agrees to indemnify and
hold  harmless  each  Underwriter  and each  person,  if any,  who  controls any
Underwriter  within  the  meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act to the extent and in the manner as set forth below:

                  (i) against  any and all loss,  liability,  claim,  damage and
                  expense  whatsoever,  as  incurred,  arising out of any untrue
                  statement  or alleged  untrue  statement  of a  material  fact
                  contained  in the  Registration  Statement  (or any  amendment
                  thereto), including the Rule 430A Information and the Rule 434
                  Information,   if  applicable,  or  the  omission  or  alleged
                  omission  therefrom of a material  fact  required to be stated
                  therein  or  necessary  to make  the  statements  therein  not
                  misleading  or arising out of any untrue  statement or alleged
                  untrue   statement  of  a  material  fact   contained  in  any
                  preliminary  prospectus or the Prospectus (or any amendment or
                  supplement  thereto),  or the  omission  or  alleged  omission
                  therefrom  of a material  fact  necessary in order to make the
                  statements  therein,  in the light of the circumstances  under
                  which they were made, not misleading;

                  (ii) against any and all loss,  liability,  claim,  damage and
                  expense  whatsoever,   as  incurred,  to  the  extent  of  the
                  aggregate amount paid in settlement of any litigation,  or any
                  investigation  or  proceeding  by any  governmental  agency or
                  body,  commenced  or  threatened,  or of any claim  whatsoever
                  based upon any such untrue statement or omission,  or any such
                  alleged untrue  statement or omission;  provided that any such
                  settlement  is  effected  with  the  written  consent  of  the
                  Company; and

                  (iii)  against  any and all  expense  whatsoever,  as incurred
                  (including  the fees and  disbursements  of counsel  chosen by
                  [Name]),  reasonably  incurred in investigating,  preparing or
                  defending  against any  litigation,  or any  investigation  or
                  proceeding by any  governmental  agency or body,  commenced or
                  threatened, or any claim whatsoever based upon any such untrue
                  statement or omission, or any such alleged untrue statement or
                  omission,  to the  extent  that any such  expense  is not paid
                  under  (i)  or  (ii)  above;  provided,   however,  that  this
                  indemnity  agreement  shall not apply to any loss,  liability,
                  claim,  damage or  expense to the  extent  arising  out of any
                  untrue  statement or omission or alleged  untrue  statement or
                  omission made in reliance upon and in conformity  with written
                  information  furnished  to  the  Company  by  any  Underwriter
                  through  [Name],   expressly  for  use  in  the   Registration
                  Statement (or any amendment thereto),  including the Rule 430A
                  Information and the Rule 434  Information,  if applicable,  or
                  any preliminary prospectus or the Prospectus (or any amendment
                  or  supplement   thereto);   and  provided  further  that  the
                  foregoing indemnity with respect to any preliminary prospectus
                  shall not inure to the benefit of any  Underwriter  (or to the
                  benefit of any person  controlling such Underwriter) from whom
                  the person asserting any such loss, liability, claim or damage


                                                       
15

                  purchased  Securities if such untrue  statement or omission or
                  alleged untrue  statement or omission made in such preliminary
                  prospectus  is eliminated  or remedied in the  Prospectus  (as
                  amended or  supplemented  by the Company if the Company  shall
                  have furnished any  amendments or  supplements  thereto) and a
                  copy of the Prospectus (as so amended or supplemented),  which
                  at such time had been provided to the  Underwriters  for their
                  use,  shall not have been furnished to such person at or prior
                  to the written confirmation of sale of such Securities to such
                  person.

         (b)  Indemnification  by the Underwriters.  Each Underwriter  severally
agrees to indemnify and hold harmless the Company,  its  directors,  each of its
officers who signed the  Registration  Statement,  and each person,  if any, who
controls the Company within the meaning of Section 15 of the 1933 Act or Section
20 of the 1934 Act, and the Company, against any and all loss, liability, claim,
damage and expense  described in the indemnity  contained in  subsection  (a) of
this  Section,  as  incurred,  but only with  respect  to untrue  statements  or
omissions,  or alleged untrue statements or omissions,  made in the Registration
Statement (or any amendment  thereto),  including the Rule 430A  Information and
the Rule 434 Information,  if applicable,  or any preliminary  prospectus or the
Prospectus  (or any  amendment or  supplement  thereto) in reliance  upon and in
conformity with written information furnished to the Company by such Underwriter
through [Name] expressly for use in the Registration Statement (or any amendment
thereto) or such  preliminary  prospectus or the Prospectus (or any amendment or
supplement thereto).

         (c) Actions against Parties; Notification. Each indemnified party shall
give notice as promptly as reasonably  practicable to each indemnifying party of
any action  commenced  against it in  respect of which  indemnity  may be sought
hereunder, but failure to so notify an indemnifying party shall not relieve such
indemnifying  party  from  any  liability  hereunder  to  the  extent  it is not
materially  prejudiced as a result thereof and in any event shall not relieve it
from any liability which it may have otherwise than on account of this indemnity
agreement.  In the case of parties  indemnified  pursuant to Section 6(a) above,
counsel to the indemnified  parties shall be selected by [Name], and in the case
of  parties  indemnified   pursuant  to  Section  6(b)  above,  counsel  to  the
indemnified  parties shall be selected by the Company. An indemnifying party may
participate  at its own  expense in the  defense of any such  action;  provided,
however,  that  counsel to the  indemnifying  party shall not  (except  with the
consent of the indemnified  party) also be counsel to the indemnified  party. In
no event shall the indemnifying  parties be liable for fees and expenses of more
than one counsel  (in  addition to any local  counsel)  separate  from their own
counsel  for all  indemnified  parties  in  connection  with any one  action  or
separate but similar or related actions in the same jurisdiction  arising out of
the same general  allegations or  circumstances.  No  indemnifying  party shall,
without  the  prior  written  consent  of the  indemnified  parties,  settle  or
compromise  or  consent  to  the  entry  of any  judgment  with  respect  to any
litigation,  or any  investigation or proceeding by any  governmental  agency or
body,  commenced  or  threatened,  or any claim  whatsoever  in respect of which
indemnification  or contribution could be sought under this Section 6 or Section
7 hereof (whether or not the indemnified parties are actual or potential parties
thereto),  unless  such  settlement,  compromise  or  consent  (i)  includes  an
unconditional  release of each indemnified  party from all liability arising out
of such litigation, investigation, proceeding or claim and (ii) does not include
a statement as to or an admission of fault,  culpability  or a failure to act by
or on behalf of any indemnified party.


                                                       
16

         SECTION 7. Contribution. If the indemnification provided for in Section
6 hereof is for any reason  unavailable to or  insufficient  to hold harmless an
indemnified  party (other than pursuant to the terms  thereof) in respect of any
losses, liabilities,  claims, damages or expenses referred to therein, then each
indemnifying  party shall  contribute  to the  aggregate  amount of such losses,
liabilities, claims, damages and expenses incurred by such indemnified party, as
incurred,  (i) in such  proportion  as is  appropriate  to reflect the  relative
benefits  received  by the Company on the one hand and the  Underwriters  on the
other hand from the  offering of the  Securities  pursuant to this  Agreement or
(ii) if the  allocation  provided by clause (i) is not  permitted by  applicable
law, in such  proportion  as is  appropriate  to reflect  not only the  relative
benefits  referred  to in clause  (i) above but also the  relative  fault of the
Company on the one hand and of the  Underwriters on the other hand in connection
with the  statements  or omissions  that  resulted in such losses,  liabilities,
claims,   damages  or  expenses,   as  well  as  any  other  relevant  equitable
considerations.

         The relative  benefits  received by the Company on the one hand and the
Underwriters on the other hand in connection with the offering of the Securities
pursuant  to  this  Agreement  shall  be  deemed  to be in the  same  respective
proportions  as the total  net  proceeds  from the  offering  of the  Securities
pursuant to this Agreement (before deducting  expenses)  received by the Company
and the total underwriting  discount received by the Underwriters,  in each case
as set  forth  on the  cover of the  Prospectus,  or,  if Rule 434 is used,  the
corresponding  location on the Term Sheet bear to the aggregate  initial  public
offering price of the Securities as set forth on such cover.

         The relative fault of the Company on the one hand and the  Underwriters
on the other hand shall be  determined  by  reference  to,  among other  things,
whether  any such  untrue or alleged  untrue  statement  of a  material  fact or
omission or alleged  omission to state a material  fact  relates to  information
supplied by the Company or by the Underwriters and the parties' relative intent,
knowledge,  access to  information  and  opportunity  to correct or prevent such
statement or omission.

         The  Company and the  Underwriters  agree that it would not be just and
equitable if contribution pursuant to this Section 7 were determined by pro rata
allocation  (even  if the  Underwriters  were  treated  as one  entity  for such
purpose) or by any other method of allocation which does not take account of the
equitable  considerations  referred  to above in this  Section 7. The  aggregate
amount of losses,  liabilities,  claims,  damages  and  expenses  incurred by an
indemnified  party and  referred  to above in this  Section 7 shall be deemed to
include any legal or other  expenses  reasonably  incurred  by such  indemnified
party in investigating,  preparing or defending  against any litigation,  or any
investigation  or proceeding by any  governmental  agency or body,  commenced or
threatened, or any claim whatsoever based upon any such untrue or alleged untrue
statement or omission or alleged omission.

         Notwithstanding  the provisions of this Section 7, no Underwriter shall
be required to contribute  any amount in excess of the amount by which the total
price at which the Securities  underwritten  by it and distributed to the public
were  offered  to the  public  exceeds  the  amount of any  damages  which  such
Underwriter  has otherwise  been required to pay by reason of any such untrue or
alleged untrue statement or omission or alleged omission.

         No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

         For purposes of this  Section 7, each  person,  if any, who controls an
Underwriter  within  the  meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act shall have the same rights to contribution as such Underwriter, and
each  director  of the  Company,  each  officer  of the  Company  who signed the
Registration Statement, and each person, if any, who controls the Company within
the  meaning  of  Section 15 of the 1933 Act or Section 20 of the 1934 Act shall
have  the  same  rights  to  contribution  as  the  Company.  The  Underwriters'
respective  obligations to contribute  pursuant to this Section 7 are several in
proportion to the number of Securities set forth opposite their respective names
in Schedule A hereto and not joint.

         SECTION  8.  Representations,  Warranties  and  Agreements  to  Survive
Delivery.  All  representations,  warranties  and  agreements  contained in this
Agreement,  or in  certificates  of officers of the Company  submitted  pursuant
hereto,  shall remain operative and in full force and effect,  regardless of any
investigation made by or on behalf of any Underwriter or controlling  person, or
by or on behalf of the Company,  and shall survive delivery of the Securities to
the Underwriters.

         SECTION 9.  Termination of Agreement.

         (a)  Termination;   General.  The  Representative  may  terminate  this
Agreement, by notice to the Company, at any time at or prior to Closing Time (i)
if there has been,  since the time of execution  of this  Agreement or since the
respective  dates  as of which  information  is  given  in the  Prospectus,  any
material adverse change, or development involving a prospective material adverse
change,  in the financial  condition,  results of  operations  or  stockholders'
equity of the Company and its subsidiaries considered as one enterprise, whether
or not arising in the ordinary course of business, or (ii) if there has occurred
any material adverse change in the financial  markets in the United States,  any
outbreak of hostilities or escalation thereof or other calamity or crisis or any
material  change or  development  involving  a  prospective  material  change in
national or international political,  financial or economic conditions,  in each
case  the  effect  of  which  is such  as to make  it,  in the  judgment  of the
Representative,  impracticable to market the Securities or to enforce  contracts
for the sale of the  Securities,  or (iii) if trading in any  securities  of the
Company has been  suspended or limited by the  Commission  or the New York Stock
Exchange, or if trading generally on the American Stock Exchange or the New York
Stock Exchange or in the NASDAQ  National  Market has been suspended or limited,
or minimum or maximum prices for trading have been fixed,  or maximum ranges for
prices  have been  required,  by any of said  exchanges  or by such system or by
order of the Commission,  the NASD or any other governmental  authority, or (iv)
if a  banking  moratorium  has  been  declared  by  either  Federal  or New York
authorities.

                                                       

18


         (b)  Liabilities.  If this  Agreement  is  terminated  pursuant to this
Section,  such termination  shall be without liability of any party to any other
party except as provided in Section 4 hereof, and provided further that Sections
1, 6 and 7 shall survive such termination and remain in full force and effect.

         SECTION 10. Default by One or More of the Underwriters.  If one or more
of the Underwriters  shall fail at Closing Time to purchase the Securities which
it or they are  obligated  to  purchase  under this  Agreement  (the  "Defaulted
Securities"),   the  Representative  shall  have  the  right,  within  24  hours
thereafter,  to  make  arrangements  for  one  or  more  of  the  non-defaulting
Underwriters, or any other underwriters, to purchase all, but not less than all,
of the  Defaulted  Securities in such amounts as may be agreed upon and upon the
terms herein set forth; if, however, the Representative shall not have completed
such  arrangements  within  such  24-hour  period,  then:  (a) if the  number of
Defaulted  Securities  does not  exceed 10% of the  number of  Securities  to be
purchased  on  such  date,  each of the  non-defaulting  Underwriters  shall  be
obligated, severally and not jointly, to purchase the full amount thereof in the
proportions that their respective underwriting obligations hereunder bear to the
underwriting  obligations  of  all  non-defaulting  Underwriters,  or (b) if the
number of Defaulted  Securities  exceeds 10% of the number of  Securities  to be
purchased on such date, this Agreement shall terminate  without liability on the
part of any non-defaulting Underwriter.

         No action taken  pursuant to this Section shall relieve any  defaulting
Underwriter from liability in respect of its default.

         In the event of any such default which does not result in a termination
of this Agreement, either the Representative or the Company shall have the right
to postpone  Closing Time,  for a period not  exceeding  seven days, in order to
effect any required  changes in the  Registration  Statement or Prospectus or in
any other  documents or  arrangements.  As used herein,  the term  "Underwriter"
includes any person substituted for an Underwriter under this Section 10.

         SECTION 11.  Default by the  Company.  If the  Company  shall make such
delivery  but  the  Company  shall  fail  to  deliver  the   Securities  to  the
Representative,  then the Underwriters may, at the option of the Representative,
by notice from the  Representative  to the  Company,  terminate  this  Agreement
without any liability on the fault of any  non-defaulting  party except that the
provisions  of Sections 1, 4, 6 and 7 shall remain in full force and effect.  No
action taken pursuant to this Section 11 shall relieve the defaulting party from
liability, if any, in respect of such default.

         SECTION 12.  Notices.  All notices and other  communications  hereunder
shall be in  writing  and shall be  deemed to have been duly  given if mailed or
transmitted  by  any  standard  form  of   telecommunication.   Notices  to  the
Underwriters  shall be directed to the  Representative at  ____________________,
attention of  ___________________;  notices to the Company  shall be directed to
Chief Financial Officer, Bank of Oklahoma, National Association,  P.O. Box 2300,
Tulsa,  Oklahoma 74192 and Frederic  Dorwart,  Lawyers,  Old City Hall, 124 East
Fourth Street, Tulsa, Oklahoma 74103-5010.

         SECTION 13.  Parties.  This Agreement shall inure to the benefit of and
be binding upon each of the  Underwriters  and the Company and their  respective
successors.  Nothing  expressed or  mentioned  in this  Agreement is intended or
shall be  construed  to give any  person,  firm or  corporation,  other than the
Underwriters and the Company and their respective successors and the controlling
persons and  officers  and  directors  referred to in Sections 6 and 7 and their
heirs and legal  representatives,  any legal or equitable right, remedy or claim
under or in respect of this Agreement or any provision  herein  contained.  This
Agreement and all conditions  and  provisions  hereof are intended to be for the
sole and  exclusive  benefit  of the  Underwriters  and the  Company  and  their
respective  successors,  and said controlling persons and officers and directors
and their  heirs  and legal  representatives,  and for the  benefit  of no other
person,  firm or  corporation.  No purchaser of Securities  from any Underwriter
shall be deemed to be a successor by reason merely of such purchase.

     SECTION 14. GOVERNING LAW AND TIME. THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED  IN  ACCORDANCE  WITH THE LAWS OF THE  STATE OF NEW  YORK.  EXCEPT  AS
OTHERWISE SET FORTH HEREIN, SPECIFIED TIMES OF DAY REFER TO OKLAHOMA TIME.

     SECTION 15. Effect of Headings. The Article and Section headings herein and
the  Table of  Contents  are for  convenience  only and  shall  not  affect  the

agreement,  please  sign and  return  to the  Company [ ]  counterparts  hereof,
whereupon this  agreement,  along with all  counterparts,  will become a binding

          For itself and as  Representative of the other  Underwriters  named in

                                    EXHIBIT A


                    OPINION OF THE COMPANY'S SPECIAL COUNSEL
                    TO BE DELIVERED PURSUANT TO SECTION 5(b)

         The opinions of special counsel for the Company  referred to in Section
5(b) collectively shall be substantially to the following effect:

         (i)      The  Company  has been duly  incorporated  and is an  existing
                  corporation  in good  standing  under the laws of the State of
                  Oklahoma.  The Company has the requisite  corporate  power and
                  authority to conduct its business in all material  respects as
                  described in the Prospectus.

         (ii)     The  Securities  have been duly  authorized and validly issued
                  and are fully paid and nonassessable.

         (iii)    The  statements  set forth under the heading  "Description  of
                  Senior Debt  Securities"  in the  Prospectus,  insofar as such
                  statements purport to be a summary of the instruments defining
                  the rights of holders of the Securities is accurate,  complete
                  and fair in all material respects.

         (iv)     All regulatory consents, authorizations, approvals and filings
                  required  to be  obtained  or made by the  Company  under  the
                  Federal  laws of the United  States,  the laws of the State of
                  Oklahoma  and the  General  Corporation  Law of the  State of
                  Oklahoma for the issuance, sale and delivery of the Securities
                  by the Company have been obtained or made.

         (v)      The issuance of the  Securities by the Company  hereunder does
                  not (a) violate the Company's  certificate of incorporation or
                  by-laws,  (b)  result  in a  default  under or  breach  of the
                  agreements  listed in Annex A to this  opinion or (c)  violate
                  any  Federal  law of the United  States or law of the State of
                  Oklahoma applicable to the Company;  provided,  however, that,
                  for  purposes of this  paragraph  (vi),  such counsel need not
                  express an opinion with respect to Federal or state securities
                  laws, other antifraud laws or fraudulent transfer laws.

         (vi)     The Underwriting Agreement has been duly authorized,  executed
                  and  delivered by the  Company.  The  Indenture  has been duly
                  qualified  under  the  Trust  Indenture  Act and has been duly
                  authorized,  executed  and  delivered  by the Company and is a
                  valid and binding  agreement  of the Company,  enforceable  in
                  accordance  with its term,  subject to applicable  bankruptcy,
                  insolvency  or  similar  laws  affecting   creditors'   rights
                  generally and general principles of equity.


                                                       
22


         In  addition,  such  counsel  shall state that they have  reviewed  the
Registration Statement and the Prospectus,  participated in discussions with the
Representative  and the  representatives  of the Company and its accountants and
that,  on  the  basis  of  the  information  gained  in  such  discussions,  the
Registration Statement, as of the date it became effective,  and the Prospectus,
as of the date of the  Prospectus,  appeared  on their face to be  appropriately
responsive in all material  respects to the requirements of the 1933 Act and the
1933 Act Regulations. Further, such counsel shall confirm that nothing that came
to their attention in the course of the aforementioned review has caused them to
believe that the  Registration  Statement,  as of the date it became  effective,
contained  any  untrue  statement  of a  material  fact or  omitted to state any
material fact required to be stated  therein or necessary to make the statements
therein not misleading or that the Prospectus,  as of the date of the Prospectus
and as of the Closing Date, contained any untrue statement of a material fact or
omitted to state any material  fact  necessary  in order to make the  statements
therein,  in the light of the  circumstances  under  which they were  made,  not
misleading.

         The  limitations  inherent in the  independent  verification of factual
matters and the character of determinations involved in the registration process
are  such,  however,  that such  counsel  shall not be  required  to assume  any
responsibility  for the  accuracy,  completeness  or fairness of the  statements
contained in the Registration  Statement or the Prospectus except for those made
under the captions "Description of Senior Debt Securities" and "Underwriting" in
the  Prospectus  insofar  as they  relate to  provisions  of  documents  therein
described.  Also,  such counsel need not express any opinion or belief as to the
financial  statements  or other  financial  data  contained in the  Registration
Statement of the Prospectus.
