Holders of ONEOK Inc. Common Stock are entitled to (1) vote for each share held
of record.  Subject to the preferential rights of the holders of the
Corporation's Preferred Stock and Preference Stock, the holders of Common Stock
are entitled to receive any Dividends that may be declared by the Corporation's

in the net assets of the Corporation upon liquidation.  Holders of Common Stock

Rights Plan, to purchase one one-hundredth (1/100) of a share of Series A

                     INTERESTS OF NAMED EXPERTS AND COUNSEL


The legality of the securities which may be purchased under the Plan has been
passed upon by the firm of Arrington Kihle Gaberino & Dunn, Inc., 100 West
Fifth Street, Suite 1000, Tulsa, Oklahoma 74103, counsel for the Company.  The
firm of Arrington Kihle Gaberino & Dunn, Inc., has reviewed the statements made
as to matters of law and legal conclusions under "Securities to be Offered" and
such statements are set forth in the documents which form a part of the
prospectus in reliance upon its authority as an expert.


                                     ITEM 6
                   INDEMNIFICATION OF DIRECTORS AND OFFICERS


Pursuant to Article VIII of the bylaws of the Company, upon authorization and
determination either (1) by the board of directors by a majority of a quorum
consisting of directors who were not parties to the action, suit, or proceeding
involved; (2) if such a quorum is not obtainable, or even if obtainable and a
quorum of disinterested directors so directs, by independent counsel in a
written opinion; or (3) by the stockholders, the Company is obligated to
indemnify any person who incurs liability by reason of the fact that he is or
was a director, officer, employee, or agent of the Company, or is or was
serving at its request as a director, officer, employee, or agent of another
corporation, partnership, joint venture, trust or other enterprise, or as a
member of any committee or similar body, if he acted in good faith and in a
manner he reasonably believed to be in or not opposed to the best interests of
the Company, and with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful.  However, in an action by
or in the right of the Company, no indemnification will be made if such person
shall be adjudged to be liable to the Company, unless such indemnification is
allowed by a court of competent jurisdiction.

Under insurance contracts obtained by the Company, coverage of Company officers
and directors against liability for neglect, errors, omissions, or breaches of
duty in their capacities as such is provided for both the Company, to the
extent that it is obligated to indemnify such officers and directors, and the
officers and directors themselves.  Such coverage is provided in the amount of
$75,000,000 with a retained limit by the Company of $250,000.  The insurance
companies are obligated to pay covered losses in excess of the $250,000
retained limit, up to the policies' limits of $75,000,000.  Among the policies'
exclusions are those which exclude coverage for accounting for profits made
within the meaning of Section 16(b) of the Securities Act of 1934, claims based
upon or attributable to directors and officers gaining any personal profit or
advantage to which such individuals are not legally entitled, and for any
claims brought about or attributable to the dishonesty of an officer or
director.

The registrant has been advised that, in the opinion of the Securities and
Exchange Commission, provisions providing for the indemnification by a
corporation of its officers, directors, and controlling persons against
liabilities imposed by the Securities Act of 1933 are against public policy as
expressed in said Act and are therefore unenforceable.  It is recognized that
the above-summarized provisions of the registrant's bylaws and the applicable
Delaware General Corporation Law may be sufficiently broad to indemnify
officers, directors, and controlling persons of the registrant against
liabilities arising under said Act.  Therefore, in the event that a claim of
indemnification against liability under said Act (other than the payment by the
registrant of expenses incurred or paid by a director, officer, or controlling
person of the registrant in the successful defense of any action, suit, or
proceeding) shall be asserted by an officer, director, or controlling person
under said provisions, the registrant will, unless in the opinion of its
counsel the question has already been settled by controlling precedent, submit
to a court of appropriate jurisdiction the question of whether or not such
indemnification by it is against public policy as expressed in said Act and
will be governed by the final adjudication of such issue.

                                  UNDERTAKINGS


         a.      The undersigned registrant hereby undertakes:

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

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

                 (b)      To reflect in the prospectus any facts or events
                          arising after the effective date of the registration
                          statement (or the 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;

                 (c)      To include any material information with respect to
                          the Plan of distribution not previously disclosed in
                          the registration statement or any material change to
                          such information in the registration statement.

                          Provided, however, that paragraphs a. (1) (a) and a.
                          (1) (b) do not apply if the information required to
                          be included in a post-effective amendment by those
                          paragraphs is contained in periodic reports filed by
                          the registrant pursuant to Section 13 or Section
                          15(d) of the Securities Exchange Act of 1934 that are
                          incorporated by reference in the registration
                          statement.

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

c.       The undersigned registrant hereby undertakes to deliver or cause to be
         delivered with the prospectus to each employee to whom the prospectus
         is sent or given, the latest Annual Report to Shareholders unless such
         employee otherwise has received a copy of such report, in which case
         the registrant shall state in the prospectus that it will promptly
         furnish, without charge, a copy of such report on written request of
         the employee.  If the last fiscal year of the registrant has ended
         within 120 days prior to the use of the prospectus, the Annual Report
         of the registrant of the preceding fiscal year may be so delivered,
         but within such 120-day period the Annual Report for the last fiscal
         year will be furnished to each such employee.

         The undersigned registrant hereby undertakes to transmit or cause to
         be transmitted to all employees participating in the Plan who do not
         otherwise receive such material as stockholders of the registrant, at
         the time and in the manner such material is sent to its stockholders,
         copies of all reports, proxy statements, and other communications
         distributed to its stockholders generally.

d.       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





                                       6
<PAGE>   7
         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 a 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

referred to as the "Company"), will file with the Securities and Exchange
Commission under the Securities Act of 1933, as amended, a Form S-8
Registration Statement relating to the registration of Plan interests, and
registration of shares of the Company's Common Stock with respect to the Thrift
Plan for Employees of ONEOK Inc. and Subsidiaries (the "Plan").

         We have examined (a) the above-mentioned Registration Statement which
will be filed with the Securities and Exchange Commission; (b) the Third
Restated Certificate of Incorporation and Bylaws of the Company, as amended;
(c) the Thrift Plan for Employees of ONEOK Inc. and Subsidiaries and the
corporate actions taken by the Board of Directors in connection with the
Registration Statement and related matters; and (d) such other corporate
records, certificates of public officials and officers of the Company and other
documents as we have considered relevant to the matters covered by this
opinion.

         In connection with the foregoing, as counsel for the Company, we wish
to advise you as follows:

         1.      The Company is a corporation validly organized and existing
under the laws of the State of Delaware and is duly qualified to do business as
a foreign corporation in the State of Oklahoma.

         2.      The filing of the above-mentioned Registration Statement has
been duly authorized by the proper corporate action on the part of the Company.

         3.      Assuming the Shares are being issued in compliance with the
terms and conditions of the Plan, when the certificates for the Shares have
been executed by the proper officer of the Company, countersigned by the
Transfer Agent and registered by the Registrar thereof, the certificates for
such Shares will represent, and the Shares will constitute, duly authorized,
legally issued, fully paid, non-assessable, valid and legal shares of the
Common Stock of the Company.

         4.      When an employee of the Company becomes a participant in the
Plan, such employee is thereby entitled to an interest in the Plan according to
the provisions of the Plan and the elections made by the participant from time
to time.  Such interests in the Plan, when created in accordance with the
provisions of the Plan, will constitute legally issued, fully paid and
non-assessable interests except as may be set forth in the Plan.

         The statements of law and legal conclusions made in the documents
constituting the prospectus furnished in connection with the Registration
Statement pertaining to the Employee Retirement Income Security Act of 1974, as
amended ("ERISA"), have been reviewed by us and are correct.  Where
appropriate, the Plan described in the documents constituting the prospectus
has been amended to comply with ERISA, and in such manner that such Plan, as
necessary, may be qualified under the provisions of the Internal Revenue Code
of 1986, as amended ("Code").  The Plan has been qualified under the Code.  A
copy of the favorable determination letter from the Internal Revenue Service
("IRS") dated June 7, 1993, concerning the Plan has been considered.  Since
that determination, amendments to that Plan have been made to restate the Plan
to conform to the requirements of ERISA and to the extent required by the
provisions of the Code and applicable regulations of the IRS affecting its
qualification.  Subject only to the foregoing, it is our opinion that the
written documents comprising the Plan comply with ERISA and the Code.

         We hereby consent to:

         1.      Being named in the Form S-8 Registration Statement and
documents constituting the prospectus which is being furnished, and in any
amendments thereto, as counsel for the Company, passing on legal matters in
connection with the issuance of the Common Stock to the Trustee under the Plan;

                                               Participant taken into account under this Plan for any year shall not exceed 
                                               two hundred thousand dollars ($200,000) in the years beginning after December 
                                               31, 1988, and before January 1, 1994, (such two hundred thousand dollars 
                                               ($200,000) amount to be adjusted to reflect increases in the cost-of- living 
                                               in accordance with Code Sections 401(a)(17) and 415(d)).  In addition to other

                                               provision of the Plan to the contrary, for Plan Years beginning on or after 
                                               January 1, 1994, the annual compensation of each Employee taken into account 
                                               under the Plan shall not exceed the OBRA '93 annual compensation limit. The 
                                               OBRA '93 annual compensation limit is $150,000, as adjusted by the Commissioner
                                               of the Internal Revenue Service for increases in the cost-of-living in accordance
                                               with Code Section 401(a)(17)(B).  The cost-of-living adjustment in effect for 
                                               a calendar year applies to any period, not exceeding 12 months, over which 
                                               compensation is determined (determination period) beginning in such calendar 
                                               year.  If a determination period consists of fewer than 12 months, the OBRA 
                                               '93 annual compensation limit will be multiplied by a fraction, the numerator 
                                               of which is the number of months in the determination period, and the denominator 
                                               of which is 12.  For Plan Years beginning on or after January 1, 1994, any 
                                               reference in this Plan to the limitation under Section 401(a)(17) of the Code 
                                               shall mean the OBRA '93 annual compensation limit set forth in this provision.  
                                               If compensation for any prior determination period is taken into account in 
                                               determining an Employee's benefits accruing in the current Plan Year, the

                                               portion of Excess Deferrals from the Plan, such portion shall be treated
                                               as a contribution of the Company for purposes of applying the limitations
                                               in paragraphs 3. and 4. of this Article VIII and Code Section

                                                    may, at any time prior to the tender offer withdrawal date, instruct

                                               Article XI, notwithstanding any other provisions of the Plan, the payment
                                               of benefits under the Plan to the Participant will begin not later than

                                               which:

                                               a.   the Participant attains the age sixty-five (65),

                                               b.   occurs the tenth (10th) anniversary of the year in which the
                                                    Participant commenced participation in the Plan, or

                                               c.   the Participant terminates employment with the Company.

  5.     Participant Election                  A Participant whose employment with the Company is terminated by retirement or 
         to Defer Distribution                 for any reason other than death, may make an affirmative election to defer the 
                                               distribution of his/her account if it exceeds three thousand five hundred dollars

                                               affirmative election of deferral of distribution is separate and distinct from the
                                               requirement of consent to immediate distribution stated in paragraph 3.
                                               of this Article XI, and shall apply independently thereof.  It shall be

                                               prescribed by the Committee, signed by the Participant and delivered by

                                               Participant's retirement or separation from service.

  6.     Sequence of Deferred                  If a Participant refuses consent to immediate distribution of his/her account under

         Distribution of                       paragraph 5. of this Article XI, his/her account shall continue to be     
         Accounts (Continued)                  maintained in the Trust in the manner provided by the Plan.  Subject to   
                                               the prior approval and consent of the Committee, the Participant may at   
                                               any time thereafter request in writing that distribution of his/her       
                                               account be made.  When such a request is approved by the Committee, the

                                               that such a deferred distribution of a Participant's account shall be     
                                               only in the following sequence:  first, either all of his/her account, or

                                               account not previously distributed; thus, all of a Participant's          
                                               contributions must be distributed to him/her at one time, and no Company

                                               distribution hereunder may thereafter request and receive only a single   
                                               distribution of the balance of his/her account.  No earnings credited to  
                                               the account of a Participant can be distributed to him/her after his/her  
                                               termination of employment with the Company without liquidating the total  
                                               account balance.                                                          
                                                                                                                         

  7.     Deferred Distribution                 A Participant who makes the affirmative election to defer the distribution of 
         at Age Seventy (70)                   his/her account under paragraph 5. of this Article XI, shall in all events have 
                                               any undistributed balance of his/her account paid and distributed to him/her not 
                                               later than the first day of the month next following the date on which he/she

                                               such reduction to the Participant would otherwise be permissible under the Plan.  
                                               A plan loan will not be considered to be a distribution or reduction of the

                                               Any such loan shall be made upon application of the Participant, and on
                                               terms acceptable to the Committee in an amount which when added to the
                                               outstanding balance of all other loans from the Plan to the Participant
                                               does not exceed the lesser of (i) fifty thousand dollars ($50,000),
                                               reduced by the excess (if any) of (a) the highest outstanding balance of
                                               loans from the Plan during the one (1)-year period ending on the day
                                               before the date on which such loan was made, over (b) the outstanding
                                               balance of loans from the Plan on the date on which such loan was made,

                                               benefit of the Participant under the Plan.  Such loan shall bear interest
                                               at such reasonable rate as the Committee may establish, and the Committee
                                               shall make such arrangements for adequate security and repayment as are
                                               reasonable under the circumstances.  The Committee shall require the
                                               prior written consent of the Participant and, if married, the
                                               Participant's spouse, with respect to any loan which is secured by such
                                               married Participant's accrued benefit under this Plan.  The written
                                               consent of the Participant's spouse shall acknowledge the effect thereof
                                               and be witnessed by a Plan representative or notary public.  Any such
                                               loan shall by its terms be required to be repaid within five (5) years,

  1.     Minimum Contribution                  If this Plan is top heavy in any Plan Year beginning after December 31,
                                               1983, the Plan guarantees a minimum contribution of three percent (3%) of
                                               Compensation for each Non-key Employee who is a Participant employed by
                                               the Company on the last day of the Plan Year.  If the contribution rate
                                               for the Key Employee with the highest contribution rate is less than
                                               three percent (3%), the guaranteed minimum contribution for Non-key
                                               Employees under this paragraph 1. shall equal the highest contribution
                                               rate received by a Key Employee.  The contribution rate is the sum of
                                               Company contributions (not including Company contributions to Social
                                               Security) and any forfeitures allocated to the Participant's Account for
                                               the Plan Year divided by his/her Compensation for the Plan Year taking

                                               Employees.  All qualified defined contribution plans maintained by the
                                               Company shall be considered as a single plan for purposes of determining
                                               the contribution rate.  For any year in which the Plan is top heavy, each
                                               Non-key Employee shall receive a minimum contribution if not separated
                                               from service at the end of the Plan Year regardless of whether such Non-
                                               key Employee has declined to make any mandatory contribution otherwise
                                               required by the Plan.

                                               If this Plan is top heavy and any Participant in the Plan is a
                                               Participant in any other top-heavy defined contribution plan(s)
                                               maintained by the Company, then this Plan shall provide the defined
                                               contribution plan minimum contribution for all such top-heavy defined
                                               contribution plans.

                                               If any Participant in the Plan is also covered by a top-heavy defined

                                               the Company will increase its contribution for such Employee to the extent necessary
                                               so his/her contribution rate for the Plan Year shall equal the guaranteed

                                               contributions to the Plan, the Company shall nevertheless make the

  3.     Top-Heavy Status                      The Plan is top heavy for a Plan Year if the top-heavy ratio as of the Determination 
         Determination                         Date exceeds sixty percent (60%). The top-heavy ratio is a fraction, the numerator

                                               rollovers, and other transfers, in accordance with Code Section 416 and
                                               the regulations thereunder.

                                               If the Company maintains any other qualified plans, this Plan is a top-
                                               heavy plan only if it is part of the Top-Heavy Aggregation Group, and the
                                               top-heavy ratio for both the Top-Heavy Aggregation Group and the
                                               Additional Aggregation Group exceeds sixty percent (60%).  The Committee
                                               shall calculate the top-heavy ratio and determine top-heavy status for
                                               the aggregation of plans for a particular year by the following
                                               procedures:

                                               a.   The present value of accrued benefits (including distribution to Key
                                                    Employees) is determined separately for each plan as of each plan's
                                                    Determination Date;

                                               b.   The plans are then aggregated by adding together the results for
                                                    each plan as of the Determination Dates for such plans that fall
                                                    within the same calendar year, and

                                               c.   The combined results shall indicate whether or not the plans so
                                                    aggregated are top heavy.

  4.     Top-Heavy Contribution                If the Plan is a top-heavy plan, paragraphs 2(B) and 3(B) of Code Section 415(e) 
         Limits                                shall be applied by substituting "1.0" for "1.25" therein.  Such substitution 
                                               need not be made if the minimum contribution provided for under paragraph 1. of 
                                               this Article XXI is applied by substituting "four percent (4%)" for "three percent 
                                               (3%)" therein, and if the Plan would not be a top-heavy plan if "ninety percent
                                               (90%)" were substituted for "sixty percent (60%)" wherever it appears in
                                               paragraph 3. of this Article XXI; provided, that such factor of "1.0"
                                               must always be applied under paragraphs 2(B) and 3(B) of Code Section
                                               415(e) when the top-heavy ratio for the Plan exceeds ninety percent
                                               (90%).  The transition rules as to such required substitution provided by
                                               Section 416(h)(3) of the Internal Revenue Code may be employed, if

                                               individual under the defined benefit plan of the Company.  If this Plan
                                               is a top-heavy plan and the first sentence of this paragraph 4. above,
                                               applies, then in calculating the combined limitation for a Participant in
                                               the Plan who is also a Participant in the defined benefit plan of the

                                               the Retirement Plan of the Company, the numerator of the transition
                                               fraction, if applicable, shall be forty-one thousand five hundred dollars
                                               ($41,500) instead of fifty-one thousand eight hundred seventy-five
                                               dollars ($51,875).

  5.     Vesting                               The vesting in Plan benefits for Participants provided in paragraph 1. of
                                               Article XI, shall be applicable to this Plan as a top-heavy plan.

                                               directly or indirectly on or after January 1, 1985, to the Trust of this
                                               Plan pursuant to paragraphs 1. and 2. of Article V, that vested account

                                               shall be nonforfeitable, and any income and earnings therefrom and accretions

  5.     Distributions                         Subject to paragraphs 8. and 9., below, the Transferred Participant Account of a 
                                               Participant shall not be distributed under a method of payment which, as of the

                                               established by this Article XXII or paragraph 9. of Article XI, or which is not

         (Continued)                           distribution to a Participant stated in paragraph 9. of Article XI.  In computing a
                                               minimum distribution, the life expectancy multiples under Treasury Regulations,
                                               Section 1.72-9 shall be used.  For purposes of such computation, a Participant's life
                                               expectancy may be recalculated no more frequently than annually, but the life
                                               expectancy of a nonspouse beneficiary may not be recalculated.  If the Participant's
                                               spouse is not the designated beneficiary, the method of distribution selected must
                                               provide that the present value of the payments to be made to the Participant is more
                                               than fifty percent (50%) of the present value of the total payments to the

                                               value of the Participant's nonforfeitable accrued benefit exceeds three thousand five
                                               hundred dollars ($3,500); (ii) the Qualified Joint and Survivor Annuity provisions
                                               stated below in this Article XXII apply to the distribution; and (iii) a distribution
                                               in a form other than a Qualified Joint and Survivor Annuity is to be made.
        
  7.     Time of Distribution                  If distribution of a Participant's Transferred Participant Account in other than 
                                               lump-sum is authorized by this Article XXII, then upon the death of the Participant,
                                               the Participant's Transferred Participant Account shall be paid in accordance with
                                               this paragraph.  If the Participant's death occurs after payment of the Participant's

                                               A married Participant's waiver election is not valid after December 31,
                                               1984, unless (i) the Participant's spouse (to whom the survivor annuity
                                               is payable under the Qualified Joint and Survivor Annuity) has consented
                                               in writing to the waiver election, (ii) such election designates a

                                               consent (or the consent of the spouse expressly permits designations by
                                               the Participant without any requirement of further consent by the
                                               spouse), and (iii) the spouse's consent acknowledges the effect of the
                                               election, and a notary public or the Company (or its Plan representative)
                                               witnesses the spouse's consent.  The spouse's consent to a waiver of the
                                               Qualified Joint and Survivor Annuity shall be irrevocable unless the
                                               Participant revokes the waiver election.

                                               The Company may accept as valid a waiver election which does not satisfy
                                               the spousal consent requirements, if the Company establishes the
                                               Participant does not have a spouse, the Company is not able to locate the
                                               Participant's spouse, or other circumstances exist under which the
                                               Treasury Regulations excuse the consent requirement.

                                               Notwithstanding the foregoing, a Qualified Joint and Survivor Annuity and
                                               Qualified Preretirement Survivor Annuity will not be provided unless the
