         Section  4.  The  termination  of  a  proceeding  by  judgment,  order,
settlement,  or conviction, or on a plea of nolo contenders or its equivalent is
not of itself  determinative  that the person did not meet the  requirements set
forth in Section 2 of this Article.  A person shall be deemed to have been found
liable in respect of any claim, issue or matter only after the person shall have
been so adjudged by a court of competent  jurisdiction  after  exhaustion of all
appeals therefrom.


         Section 5. A person may be indemnified  under Section 2 of this Article
against  judgments,  penalties  (including  excise and  similar  taxes),  fines,
settlement,   and  reasonable  expenses  actually  incurred  by  the  person  in
connection  with  the  proceeding;  but if the  person  is found  liable  to the
Corporation or is found liable on the basis that personal benefit was improperly
received by the person, the indemnification:

     (a) is limited to reasonable  expenses  actually  incurred by the person in
connection with the proceeding; and

         (b) shall not be made in respect of any  proceeding in which the person
shall  have been found  liable for  willful  or  intentional  misconduct  in the
performance of his duty to the Corporation.


         Section 6. A determination of  indemnification  under Section 2 of this
Article XI must be made:

     (a) by a majority vote of a quorum  consisting of directors who at the time
of the vote are not named defendants or respondents in the proceeding;

         (b) if such a  quorum  cannot  be  obtained,  by a  majority  vote of a
committee  of the  Board  of  Directors  designated  to act in the  matter  by a
majority vote of all directors,  consisting  solely of two or more directors who
at the  time  of the  vote  are  not  named  defendants  or  respondents  in the
proceeding;

         (c) by special  legal  counsel  selected by the Board of Directors or a
committee  of the  Board by vote as set forth in  Subsection  (a) or (b) of this
Section,  or, if such a quorum cannot be obtained and such a committee cannot be
established, by a majority vote of all directors; or

     (d)  by the  shareholders  in a vote  that  excludes  the  shares  held  by
directors who are named defendants or respondents in the proceeding.


         Section 7.  Authorization of  indemnification  and  determination as to
reasonableness  of expenses must be made in the same manner as the determination
that  indemnification  is  permissible,  except that if the  determination  that
indemnification  is permissible is made by special legal counsel,  authorization
of  indemnification  and  determination as to reasonableness of expenses must be
made in the manner  specified by Subsection  (C) of Section 6 of this Article XI
for the  selection  of special  legal  counsel.  A  provision  contained  in the
Articles  of  Incorporation,   the  Bylaws,  a  resolution  of  shareholders  or
directors,  or an agreement that makes mandatory the  indemnification  permitted
under Section 2 of this Article XI shall be deemed to  constitute  authorization
of  indemnification  in-the  manner  required by this Section 7 even though such
provision  may not have been  adopted or  authorized  in the same  manner as the
determination that indemnification is permissible.


         Section  8.  The  Corporation   shall  indemnify  a  director   against
reasonable  expenses incurred by him in connection with a proceeding in which he
is a named  defendant  or  respondent  because he is or was a director if he has
been  wholly  successful,  on the  merits or  otherwise,  in the  defense of the
proceeding.


         Section 9. If, in a suit for the indemnification  required by Section 8
of this  Article  XI, a court of  competent  jurisdiction  determines,  that the
director is  entitled to  indemnification  under that  Section,  the court shall
order  indemnification  and shall award to the director the expenses incurred in
securing the indemnification.


         Section 10. If, upon  application  of a director,  a court of competent
jurisdiction determines,  after giving any notice the court considers necessary,
that the director is fairly and reasonably  entitled to  indemnification in view
of all the relevant  circumstances,  whether or not he has met the  requirements
set forth in  Section 2 of this  Article XI or has been  adjudged  liable in the
circumstances described by Section 3 of this Article XI, the court may order the
indemnification  that the court  determines is proper and  equitable.  The court
shall limit  indemnification to reasonable expenses if the proceeding is brought
by or in behalf of the  Corporation  or if the  director is found  liable on the
basis that personal  benefit was improperly  received by him, whether or not the
benefit resulted from an action taken in the person's official capacity.


         Section 11. Reasonable  expenses incurred by a director who was, is, or
is threatened to be made a named  defendant or respondent in a proceeding may be
paid or reimbursed by the  Corporation,  in advance of the final  disposition of
the proceeding and without any of the determination specified in Section 6 and 7
of this Article XI, after the Corporation  receives a written affirmation by the
director  of his good  faith  belief  that he has met the  standard  of  conduct
necessary for indemnification under this Article XI and a written undertaking by
or on behalf of the  director  to repay the amount paid or  reimbursed  if it is
ultimately determined that he has not met those requirements.


         Section  12. The  written  undertaking  required  by Section 11 of this
Article XI must be an unlimited general  obligation of the director but need not
be secured.  It may be accepted without  reference to financial  ability to make
repayment.


         Section 13. A provision for the  Corporation to indemnify or to advance
expenses  to a  director  who  was,  is,  or is  threatened  to be  made a named
defendant or respondent in a  proceeding,  whether  contained in the Articles of
Incorporation,  the Bylaws,  a  resolution  of  shareholders  or  directors,  an
agreement or otherwise, except in accordance with Section 18 of this Article XI,
is valid only to the extent it is consistent  with this Article XI as limited by
the Articles of Incorporation, if such a limitation exists.


         Section 14. Notwithstanding any other provision of this Article XI, the
Corporation may pay or reimburse  expenses  incurred by a director in connection
with his  appearance  as a witness or other  participation  in a proceeding at a
time when he is not a named defendant or respondent in the proceeding.


         Section 15. An officer of the Corporation  shall be indemnified as, and
to the same  extent,  provided by Sections 8, 9, and 10 of this Article XI for a
director  and is entitled to seek  indemnification  under those  sections to the
same extent as a director. The Corporation may indemnify and advance expenses to
an officer, employee, or agent of the Corporation to the same extent that it may
indemnify and advance expenses to directors under this Article XI.


         Section 16. The  Corporation  may  indemnify  and  advance  expenses to
persons  who  are  not  or  were  not  officers,  employees,  or  agents  of the
Corporation  who are or were  serving  at the  request of the  Corporation  as a
director, officer, partner, venturer,  proprietor,  trustee, employee, agent, or
similar  functionary of another  foreign or domestic  corporation,  partnership,
joint  venturer  sole  proprietorship,  trust,  employee  benefit  plan or other
enterprise,  to the same extent that it may  indemnify  and advance  expenses to
directors under this Article XI.


         Section 17. The  Corporation  may indemnify and advance  expenses to an
officer,  employee or agent,  or person who is  identified in Section 16 of this
Article XI and who is not a director to such  further  extent,  consistent  with
law, as may be provided by the  Articles of  Incorporation,  Bylaws,  general or
specific  action of the Board of  Directors,  or  contract  or as  permitted  or
required by common law.


         Section 18. The  Corporation  may purchase  and  maintain  insurance or
another  arrangement on behalf of any person who is or was a director,  officer,
employee, or agent of the Corporation or who is or was serving at the request of
the Corporation as a director, officer, partner, venturer, proprietor,  trustee,
employee,   agent,  or  similar  functionary  of  another  foreign  or  domestic
corporation,  partnership,  joint venture, sole proprietorship,  trust, employee
benefit plan, or other  enterprise,  against any liability  asserted against him
and  incurred  by him in such a capacity  or arising out of his status as such a
person,  whether or not the  Corporation  would have the power to indemnify  him
against  that  liability  under  this  Article  XI.  If the  insurance  or other
arrangement  is with a person or entity  that is not  regularly  engaged  in the
business of providing  insurance  coverage,  the  insurance or  arrangement  may
provide for payment of a liability with respect to which the  Corporation  would
not have the power to indemnify  the person only if  including  coverage for the
additional  liability has been approved by the  shareholders of the Corporation.
Without limiting the power of the Corporation to procure or maintain any kind of
insurance or other arrangement,  the Corporation may, for the benefit of persons
indemnified by the Corporation:

         (a)      create a trust fund;

         (b)      establish any form of self-insurance;

     (c) secure its  indemnity  obligation  by grant of a security  interest  or
other lien on the assets of the Corporation; or

         (d)      establish a letter of credit, guaranty, or surety arrangement.


         The  insurance or other  arrangement  may be procured,  maintained,  or
established  within the  Corporation  or with any insurer or other person deemed
appropriate  by the Board of Directors  regardless of whether all or part of the
stock or other  securities of the insurer `or other person are owned in whole or
part by the  Corporation.  In the absence of fraud, the judgment of the Board of
Directors as to the terms and  conditions of the insurance or other  arrangement
and the identity of the insurer or other person  participating in an arrangement
shall be conclusive and the insurance or  arrangement  shall not be voidable and
shall not subject the  directors  approving  the  insurance  or  arrangement  to
liability,  on any ground,  regardless of whether directors participating in the
approval are beneficiaries of the insurance or arrangement.


         Section 19. Any indemnification of or advance of expenses to a director
in  accordance  with  this  Article  XI  shall be  reported  in  writing  to the
shareholders  with or  before  the  notice  or  waiver  of  notice  of the  next
shareholders'  meeting or with or before the next submission to the shareholders
of a consent to action without a meeting  pursuant to Section A, Article 9.10 of
the Texas Business  Corporation Act and, in any case, within the 12-month period
immediately following the date of the indemnification or advance.

         Section 20. For purposes of this Article XI, the  Corporation is deemed
to have  requested a director to serve an employee  benefit  plan  whenever  the
performance  by him of his duties to the  Corporation  also imposes duties on or
otherwise  involves services by him to the plan or participants or beneficiaries
of the plan.  Excise  taxes  assessed on a director  with respect to an employee
benefit  plan  pursuant to  applicable  law are deemed  fines.  Action  taken or
omitted by him with respect to an employee  benefit plan in the  performance  of
hisduties for a purpose reasonably  believed by him to be in the interest of the
participants  and  beneficiaries of the plan is deemed to be for a purpose which
is not opposed to the best interests of the Corporation.

                                   ARTICLE XII

                             CERTIFICATES FOR SHARES

         Section  1. The  shares of capital  stock of the  Corporation  shall be
represented by certificates  signed by the president or a vice president and the
secretary or an assistant  secretary of the  Corporation  and may be sealed with
the seal of the Corporation or a facsimile thereof.


         When the  Corporation  is  authorized  to issue shares of more than one
class,  every  certificate  shall  set  forth  upon  the  face  or  back of such
certificate, or shall state that the Corporation will furnish to any shareholder
upon  request  and  without  charge  a  full  statement  of  the   designations,
preferences,  limitations  and  relative  rights  of the  shares  of each  class
authorized  to be issued  and, if the  Corporation  is  authorized  to issue any
preferred or special class in series,  the variations in the relative rights and
preferences  between the shares of each such series so far as the same have been
fixed and  determined  and the  authority  of the Board of  Directors to fix and
determine the relative rights and preferences of subsequent series.

         Section 2. The  signatures  of the officers of the  Corporation  upon a
certificate may be facsimiles if the certificate is  countersigned by a transfer
agent or  registered  by a  registrar  other than the  Corporation  itself or an
employee  of the  Corporation.  In case  any  officer  who has  signed  or whose
facsimile  signature has been placed upon such certificate  shall have ceased to
be such  officer  before such  certificate  was issued,  it may be issued by the
Corporation  with the same effect as if he were such  officer at the date of its
issue.

                                LOST CERTIFICATES

         Section 3. The Board of Directors  may direct a new  certificate  to be
issued in place of any certificate theretofore issued by the Corporation alleged
to  have  been  lost  or  destroyed.  When  authorizing  such  issue  of  a  new
certificate,  the  Board of  Directors,  in its  discretion  and as a  condition
precedent to the issuance thereof, may prescribe such terms and conditions as it
deems  expedient,  and may require such  indemnities  as it deems  adequate,  to
protect the Corporation  from any claim that may be made against it with respect
to any such certificate alleged to have been lost or destroyed.

                               TRANSFER OF SHARES

         Section 4. Upon  surrender to the  Corporation or the transfer agent of
the  Corporation  of  a  certificate   representing   shares  duly  endorsed  or
accompanied  by proper  evidence  of  succession,  assignment  or  authority  to
transfer,  a new certificate shall be issued to the person entitled thereto, and
the old certificate  canceled and the transaction recorded upon the books of the
Corporation.

                             REGISTERED SHAREHOLDERS

         Section 5. The Corporation shall be entitled to recognize the exclusive
right of a person  registered  on its books as the  owner of  shares to  receive
dividends,  to vote as such owner and to hold liable for calls and assessments a
person registered on its books as the owner of shares, and shall not be bound to
recognize any equitable or other claim to or interest in such share or shares on
the part of any other  person,  whether  or not it shall  have  express or other
notice thereof, except as otherwise provided by the laws of Texas.

                              LIST OF SHAREHOLDERS

         Section 6. The officer or agent having charge of the transfer books for
shares  shall make,  at least ten days before each  meeting of  shareholders,  a
complete list of the shareholders entitled to vote at such meeting,  arranged in
alphabetical  order,  with the  address of each and the number of shares held by
each, which list, for a period of ten days prior to such meeting,  shall be kept
on file at the  registered  office of the  Corporation  and shall be  subject to
inspection by any shareholder at any time during usual business hours. Such list
shall also be  produced  and kept open at the time and place of the  meeting and
shall be subject to the inspection of any  shareholder  during the whole time of
the meeting. The original share ledger or transfer book, or a duplicate thereof,
shall be prima facie evidence as to who are the shareholders entitled to examine
such list or share  ledger or  transfer  book or to vote at any  meeting  of the
shareholders.

                                  ARTICLE XIII

                               GENERAL PROVISIONS

of any funds of the Corporation  available for dividends such sum or sums as the
directors  from time to time, in their  absolute  discretion,  think proper as a
reserve fund to meet contingencies or for equalizing  dividends or for repairing
or maintaining  any property of the Corporation or for such other purpose as the
Directors  shall think  conducive  to the interest of the  Corporation,  and the

of the  Corporation  and indicate that it is incorporated in the State of Texas.
The seal may be used by causing it or a  facsimile  thereof to be  impressed  or
affixed or in any  manner  reproduced.  There  shall be no  requirement  for the
Corporation to have a corporate seal.
