                  AS AMENDED AT APRIL 21, 1992




                           ARTICLE I

                      STOCK AND TRANSFERS


SECTION 1.  Each holder of fully paid stock shall be entitled  to
a  certificate  or certificates of stock stating  the  number  of
shares  owned  by  such stockholder.  All certificates  of  stock
shall  be signed by the President or a Vice President and by  the
Secretary  or  an Assistant Secretary and sealed with  the  seal,
which may be facsimile, of the Company and shall be countersigned
by  a  Transfer  Agent appointed by the Board of Directors.   All
certificates  of Preferred Stock shall also be countersigned  and
registered  by a Registrar, appointed by the Board of  Directors,
and  the  signatures of the President or Vice President  and  the
Secretary  or  Assistant Secretary upon all such certificates  of
Preferred Stock may be facsimiles, engraved or printed.  In  case
any  officer who has signed or whose facsimile signature has been
placed upon a certificate of stock shall cease to be such officer
before such certificate is issued, such certificate may be issued
by  the  Company with the same effect as if such officer had  not
ceased to be such at the date of its issue.

SECTION  2.   The capital stock of the Company shall  be  divided
into such classes, with such respective designations, preferences
and voting powers, restrictions or qualifications thereof, as are
or  shall  be  from  time to time stated  and  expressed  in  the
Articles of Incorporation of the Company, and amendments thereto.
No  holder  of shares of stock of any class of the Company  shall
have  any  preemptive or preferential rights of  subscription  or
purchase  of  any  shares of any class of stock of  the  Company,
whether  now or hereafter authorized, and any and all  shares  of
capital  stock  of  any  class of the  Company,  whether  now  or
hereafter  authorized, may, in the discretion  of  the  Board  of
Directors, be offered and sold to the holders of any one or  more
classes  of  stock of the Company to the exclusion of  any  other
class  or classes, or may be issued and disposed of from time  to
time in such manner and to such persons, whether stockholders  or
not, and for such corporate purposes as may be determined by  the
Company's  Board of Directors and without first being offered  to
stockholders.

SECTION  3.   Shares of stock shall be transferable only  on  the
books of the Company, and, except as hereinafter provided, or  as
may  be  required  by  law, or by order  of  court  in  a  proper
proceeding, shall be transferred only upon the proper  assignment
and  surrender  of  the  certificates  issued  therefor.   If  an
outstanding  certificate of stock shall  be  lost,  destroyed  or
stolen,  the  holder  thereof may have  a  new  certificate  upon
producing  evidence, satisfactory to the Board of  Directors,  of
such  loss,  destruction  or theft, and upon  furnishing  to  the
Company  a bond of indemnity, deemed sufficient by the  Board  of
Directors,  to  protect  the Company  against  claims  under  the
outstanding certificate.

SECTION  4.   The Board of Directors shall have power  to  fix  a
time,  not exceeding sixty days preceding the date of any meeting
of  stockholders,  or  the date fixed  for  the  payment  of  any
dividend or distribution or the date for the allotment of  rights
or  the  date when any change or conversion or exchange of shares
shall  be  made  or  go  into effect, as a record  date  for  the
determination of the stockholders entitled to notice  of  and  to
vote  at such meeting or entitled to receive payments of any such
dividend, distribution, or
allotment of rights, or to exercise rights in respect to any such
change,  conversion or exchange of shares, and in such case  only
registered stockholders on the date so fixed shall be entitled to
receive  notice  of said meeting or to receive  payment  of  such
dividend,  distribution, or allotment of rights, or  to  exercise
such rights of change, conversion, or exchange of shares, as  the
case  may be, notwithstanding any transfer of any shares  on  the
books  of  the Company after any record date fixed as  aforesaid;
provided,  however, that the stock transfer books of the  Company
may be closed by order of the Board of Directors for a period not
exceeding  sixty  days for the purpose of holding  a  meeting  of
stockholders,  or  paying a dividend,  or  for  any  other  legal
purpose, as the Board of Directors shall deem advisable.

SECTION  5.  If default shall be made in the prompt payment  when
due  of any sum payable to the Company upon any subscription  for
stock  of the Company, and if such default shall continue  for  a
period  of thirty days, then all right under the subscription  in
and  to  the  stock subscribed for shall, upon the expiration  of
such  period, cease and determine and become and be forfeited  to
the  Company; provided that if at the expiration of such  thirty-
day period such right shall belong to the estate of the decedent,
it  may be forfeited only by resolution of the Board of Directors
declaring  forfeiture.   The Company shall,  within  thirty  days
after such forfeiture, cause such stock to be sold at private  or
public  sale, at its market value at the time of sale, and shall,
out  of  the  net  proceeds of sale and  upon  surrender  of  any
outstanding  stock subscription receipt issued  to  evidence  the
subscription,  pay  to the recorded holder of  such  receipt  the
amount  paid  on the subscription prior to forfeiture,  less  the
amount,  if  any, by which the total subscription  price  of  the
stock exceeded the net proceeds of sale.

originated  and the Treasurer is otherwise satisfied  as  to  its
propriety  and  accuracy.  If the Treasurer is not so  satisfied,
the authority of the Chairman shall be secured before payment.

SECTION  4.   All dividends shall be declared by a  vote  of  the
Board of Directors.

SECTION 5.  The fiscal year of the company shall close at the end
of December annually.

SECTION  6.  (a)  The Corporation shall indemnify any person  who
was  or  is  a party or is threatened to be made a party  to  any
threatened,  pending  or completed action,  suit  or  proceeding,
whether  civil, criminal, administrative or investigative  (other
than  an action by or in the right of the Corporation), by reason
of  the fact that such person is or was a director or officer  of
the  Corporation  or  is or was serving at  the  request  of  the
Corporation  as  a  director or officer of  another  corporation,
joint  venture,  trust  or  other  enterprise,  against  expenses
(including attorneys' fees), judgments, fines and amounts paid in
settlement  actually and reasonably incurred by  such  person  in
connection  with such action, suit or proceeding if  such  person
acted in good faith and in a manner he or she reasonably believed
to  be in or not opposed to the best interests of the Corporation
and  is  not  determined  by the Board to  have  been  guilty  of
misconduct  in  the  performance  of  his  or  her  duty  to  the

 10
Corporation.    Provided,  however,  that  no  person  shall   be
indemnified for amounts paid in settlement, unless the terms  and
conditions  of  such  settlement have been consented  to  by  the
Corporation.   And  further provided that  with  respect  to  any
criminal  action  or proceeding, such person  had  no  reasonable
cause  to  believe  that his or her conduct  was  unlawful.   The
termination of any action, suit or proceeding by judgment, order,
settlement, conviction, or upon a plea of  nolo contendere or its
equivalent,  shall  not of itself create a presumption  that  the
person did not act in good faith and in a manner which he or  she
reasonably believed to be in or not opposed to the best interests
of  the  Corporation and, with respect to any criminal action  or
proceeding, had reasonable cause to believe that such conduct was
unlawful; provided, however, that no indemnity prohibited by  law
shall be made.

(b)   The Corporation shall indemnify any person who was or is  a
party  or  is  threatened to be made a party to  any  threatened,
pending  or  completed action or suit by or in the right  of  the
Corporation to procure a judgment in its favor by reason  of  the
fact  that  such  person is or was a director or officer  of  the
Corporation  or  is  or  was  serving  at  the  request  of   the
Corporation  as  a  director or officer of  another  corporation,
joint  venture,  trust  or  other  enterprise,  against  expenses
(including  attorneys' fees) actually and reasonably incurred  by
such  person in connection with the defense or settlement of such
action or suit if such person acted in good faith and in a manner
he or she reasonably believed to be in or not opposed to the best
interests  of  the Corporation.  Provided that no indemnification
shall  be  made in respect of any claim, issue or  matter  as  to
which  such  person shall have been adjudged  to  be  liable  for
misconduct  in  the  performance  of  his  or  her  duty  to  the
Corporation unless and only to the extent that the District Court
or  the  court  in  which such action or suit was  brought  shall
determine  upon  application that, despite  the  adjudication  of
liability but in view of all the circumstances of the case,  such
person  is fairly and reasonably entitled to indemnity  for  such
expenses which the District Court or such other court shall  deem
proper; and further provided that no indemnity prohibited by  law
shall be made.

(c)   The Corporation may indemnify, to the same extent as herein
above provided, any person who is or was an employee or agent  of
the  Corporation  or  is or was serving at  the  request  of  the
Corporation  as  an  employee or agent  of  another  corporation,
partnership,  joint  venture, trust  or  other  enterprise.   Any
indemnification under this Subsection (c) shall be made only upon
the  authorization of the Board of Directors, which may occur  at
any  time prior to, during, or after final judgment or order,  in
any  action,  suit or proceeding to which such person  is  or  is
threatened  to be made a party.  No right to such indemnification
is created by this Subsection (c).

(d)   Any  indemnification under Subsections  (a),  (b)  and  (c)
(unless ordered by a court) shall be made by the Corporation only
as  authorized  in  the specific case upon a  determination  that
indemnification of the director, officer, employee  or  agent  is
proper  in  the  circumstances because such person  has  met  the
applicable standard of conduct set forth in Subsections  (a)  and
(b).   Such  determination shall be made  (i)  by  the  Board  of
Directors  by  majority vote of a quorum consisting of  Directors
who  were not parties to such action, suit or proceeding, or (ii)
if  such  a quorum is not obtainable, or, even if obtainable,  by
independent  legal counsel in a written opinion, if a  quorum  of
disinterested directors so directs, or (iii) by the stockholders.


 11
(e)   Expenses incurred by an officer or director in defending  a
civil  or criminal action, suit or proceeding may be paid by  the
Corporation  in advance of the final disposition of such  action,
suit or proceeding as authorized by the Board of Directors in the
specific  case upon receipt of an undertaking by or on behalf  of
such  director, or officer, to repay such amount unless it  shall
ultimately  be  determined that such person  is  entitled  to  be
indemnified  by  the Corporation as authorized in  this  Section.
Such expenses incurred by other employees and agents with respect
to  which  indemnification  is  claimed  hereunder  may  also  be
advanced upon such terms and conditions, if any, as the Board  of
Directors deems appropriate.

(f)   The  Corporation  may,  as  authorized  by  the  Board   of
Directors,  purchase  and maintain insurance  on  behalf  of  any
person  who is or was a director, officer, employee or  agent  of
the  Corporation,  or is or was serving at  the  request  of  the
Corporation as a director, officer, employee or agent of  another
corporation,   partnership,  joint  venture,   trust   or   other
enterprise,  against any liability asserted against  such  person
and  incurred by him or her in any such capacity, or arising  out
of this status as such, whether or not the Corporation would have
the  power to indemnify such person against such liability  under
the provisions of this Section.

(g)  Insofar as indemnification for liabilities arising under the
Securities  Act  of 1933 may be permitted to directors,  officers
and  controlling  persons  of  the Corporation  pursuant  to  the
foregoing provisions of this Section or the laws of the state  of
Oklahoma, in the event any claim for indemnification against such
liabilities  (other  than for the payment by the  Corporation  of
expenses,  including  attorneys' fees,  actually  and  reasonably
incurred  by  a  director, officer or controlling person  of  the
Corporation  in  the successful defense of any  action,  suit  or
proceeding) is asserted against the Corporation by such director,
officer or controlling person in connection with the registration
of any security under the Securities Act of 1933, the Corporation
will,  unless in the opinion of its counsel the matter  has  been
settled   by  controlling  precedent,  submit  to  a   court   of
appropriate  jurisdiction the question whether  such  indemnifica
tion by the Corporation is against public policy as expressed  by
the  Securities  Act of 1933 and will be governed  by  the  final
adjudication of such issue.


                          ARTICLE VII


Unless otherwise ordered by the Board of Directors, the President
shall  have  full power and authority on behalf of  the  Company,
either  in person or by proxy, at any meeting of stockholders  of
any  corporation in which the Company may hold Stock and, at  any
such  meeting, may possess and exercise all the rights and powers
incident  to  the  ownership of such Stock which,  as  the  owner
thereof,  the  Company  might  have possessed  or  exercised,  if
present.

majority of the outstanding Common Stock is represented;  or  (b)
by  a  majority  vote  of the entire Board of  Directors  at  any
regular  or  special meeting duly convened after  notice  of  the
purpose of such meeting, subject to the power of the stockholders
to  alter  or  repeal such Bylaws; provided  that  the  Board  of
Directors  shall not adopt, alter or repeal any Bylaw fixing  the
number, qualifications, classifications or terms of office of the
directors, or any of them.
