                              (A Texas Corporation)


                               OFFICES AND RECORDS

1.       (a)  Registered  Office  and  Registered  Agent.  The  location  of the
registered office and the name of the registered agent of the corporation in the
State of Texas shall be as stated in the articles of  incorporation  or as shall
be  determined  from time to time by the board of  directors  and on file in the
appropriate  office of the State of Texas  pursuant to applicable  provisions of
law. Unless otherwise  permitted by law, the address of the registered office of
the corporation  and the address of the business office of the registered  agent
shall be identical.

         (b) Corporate Offices.  The corporation may have such corporate offices
anywhere  within or without  the State of Texas as the board of  directors  from
time to time may determine or the business of the corporation  may require.  The
"principal  place of  business" or  "principal  business  office" or  "executive
office" of the  corporation  may be fixed and so designated from time to time by
the board of  directors,  but the location or residence  of the  corporation  in
Texas  shall be  deemed  for all  purposes  to be in the  county  in  which  its
registered office in Texas is maintained.

2.       (a) Books and Records.  The corporation shall keep books and records of
account and minutes of the proceedings of the corporation's shareholders,  board
of directors and each committee of the board of directors. The corporation shall
keep at its registered  office or principal place of business,  or at the office
of its transfer agent or registrar,  if any, books and records in which shall be
kept a record of the original  issuance of shares and a record of each  transfer
of those shares that have been presented to the corporation for  registration of
transfer.  Such share transfer  records shall contain the names and addresses of
all past and current  shareholders of the corporation,  the number,  the series,
and the class of the  shares  owned by them  respectively,  the amount of shares
paid,  and by whom,  and the  transfer of such shares with the date of transfer.
Any books, records, minutes and share transfer records may be in written form or
in any  other  form  capable  of being  converted  into  written  form  within a
reasonable time.

         (b) Inspection of Records. Any person who shall have been a shareholder
of the corporation for at least six (6) months immediately preceding his demand,
or shall be the  registered  holder  of at least  five  percent  (5%) of all the
outstanding  shares of the corporation,  upon written demand stating the purpose
thereof, shall have the right to examine, in person or by agent, accountant,  or
attorney,  at any  reasonable  time  or  times,  for  any  proper  purpose,  the
corporation's relevant books and records of account, minutes, and share transfer
records, and to make extracts therefrom.  No shareholder shall use, permit to be
used,  or acquiesce in the use by others of any  information  so obtained to the
detriment competitively of the corporation, nor shall 
                                       1

he  furnish  or  permit to be  furnished  any  information  so  obtained  to any
competitor of the corporation.  The corporation as a condition  precedent to any
shareholder's  inspection  of the  records of the  corporation  may  require the
shareholder to indemnify the corporation,  in such manner and for such amount as
may be determined  by the board of  directors,  against any loss or damage which
may  be  suffered  by it  arising  out of or  resulting  from  any  unauthorized
disclosure  made or  permitted  to be made by such  shareholder  of  information
obtained in the course of such inspection.

                                      SEAL

3.  Corporate  Seal. The  corporation  shall have power to have a corporate seal
which  may be  altered  at  pleasure,  and to use the same by  causing  it, or a
facsimile  thereof,  to be impressed on, affixed to or in any manner  reproduced
upon, instruments of any nature required to be executed by its proper officers.

                             SHAREHOLDERS' MEETINGS

4. Place of  Meetings.  All  meetings of the  shareholders  shall be held at the
principal  business office of the corporation in Texas,  except such meetings as
the board of directors to the extent  permissible  by law  expressly  determines
shall be elsewhere, in which case such meetings may be held, upon notice thereof
as hereinafter  provided,  at such other place or places,  within or without the
State of Texas, as the board of directors shall have determined, and as shall be
stated in such notice; and, unless  specifically  prohibited by law, any meeting
may be held at any place and  time,  and for any  purpose,  if  consented  to in
writing by all of the shareholders entitled to vote thereat.

5.       (a) Annual Meetings. An annual meeting of shareholders shall be held on
a date  designated by the  corporation's  president or Board of Directors  which
date shall be not later than the last day of Novmber of each year  beginning  in
1998,  or at such  other  date as shall be  designated  from time to time by the
board of  directors  and  stated in the notice of the  meeting,  when they shall
elect a board of directors and transact  such other  business as may properly be
brought before the meeting.

         (b) Special Meetings.  Special meetings of the shareholders may be held
for any purpose or purposes and may be called by the  chairman of the board,  by
the president,  by the secretary,  by the board of directors,  or by the holders
of, or by any officer or shareholder upon the written request of the holders of,
not less than ten percent (10%) of all  outstanding  shares  entitled to vote at
any such  meeting,  and shall be called by any officer  directed to do so by the
board of directors.

         The "call" and the "notice" of any such  meeting  shall be deemed to be
synonymous.

         (c) Consent of shareholders in Lieu of Meeting.  Any action required to
be  taken  or  which  may be  taken at any  annual  or  special  meeting  of the
shareholders may be taken without a meeting, without prior notice, and without a
vote, if a consent or consents in writing, setting forth
                                       2

the action so taken, shall have been signed by all the shareholders  entitled to
vote with respect to the subject matter  thereof.  The secretary shall file such
consents with the minutes of the meetings of the shareholders.

         (d)  Meetings  by  Conference   Telephone  or  Similar   Communications
Equipment. Subject to the requirements for notices of meetings, unless otherwise
restricted  by  the  articles  of  incorporation  or  these  bylaws  or by  law,
shareholders  may  participate in and hold a meeting of shareholders by means of
conference  telephone or similar  communications  equipment  whereby all persons
participating in the meeting can hear each other, and participation in a meeting
in this manner shall constitute presence in person at such meeting, except where
a person  participates  in a meeting for the express purpose of objecting to the
transaction  of any  business  on the ground  that the  meeting is not  lawfully
called or convened.

6.       (a)  Notice.   Written  or  printed  notice  of  each  meeting  of  the
shareholders,  whether annual or special, stating the place, day and hour of the
meeting  and, in case of a special  meeting,  the  purpose or purposes  thereof,
shall be  delivered  or given to each  shareholder  of record  entitled  to vote
thereat,  either personally or by mail, by or at the direction of the president,
the secretary,  or the officer or person calling the meeting,  not less than ten
(10) nor more than sixty (60) days before the date of the meeting, unless, as to
a particular  matter,  other or further notice is required by law, in which case
such other or further notice shall be given.

         Any notice of a  shareholders'  meeting sent by mail shall be deemed to
be  delivered  when  deposited in the United  States mail with  postage  thereon
prepaid  addressed to the  shareholder at his address as it appears on the share
transfer records of the corporation.

         (b) Waiver of Notice. Whenever any notice is required to be given under
the provisions of these bylaws, of the articles of incorporation, or of any law,
a waiver  thereof in writing  signed by the person or persons  entitled  to such
notice,  whether  before  or after  the time  stated  therein,  shall be  deemed
equivalent to the giving of such notice.

         To the extent  provided  by law,  attendance  of a  shareholder  at any
meeting shall constitute a waiver of notice of such meeting.

         (c)  Presiding  Officials.  Every  meeting  of  the  shareholders,  for
whatever object, shall be convened by the president, or by the officer or any of
the persons who called the meeting by notice as above provided,  but it shall be
presided  over by the  officers  specified  in  Sections  29, 30 and 31 of these
bylaws;  provided,  however, that the shareholders at any meeting, by a majority
vote in amount of shares represented  thereat,  and notwithstanding  anything to
the  contrary  contained  elsewhere in these  bylaws,  may select any persons of
their  choosing to act as chairman and  secretary of such meeting or any session
thereof.

7.       (a) Business Which May Be Transacted at Annual Meetings. At each annual
meeting of the shareholders,  the shareholders  shall elect a board of directors
to hold  office  until  the  next  succeeding  annual  meeting  or  until  their
successors  shall have been elected and  qualified  and they may  transact  such
other business as may be desired, whether or not the same was specified 
                                       3

in the notice of the meeting,  unless the  consideration  of such other business
without  its having  been  specified  in the notice of the meeting as one of the
purposes thereof is prohibited by law.

         (b) Business  Which May Be  Transacted  at Special  Meetings.  Business
transacted at all special meetings of the shareholders  shall be confined to the
purposes stated in the notices of such meetings, unless the transaction of other
business is consented to by the holders of all the  outstanding  shares of stock
of the corporation entitled to vote thereat.

8. Quorum. Unless otherwise provided by law or by the articles of incorporation,
the  holders  of  a  majority  of  the  outstanding  shares  entitled  to  vote,
represented in person or by proxy, shall constitute a quorum for the transaction
of business at all meetings of the  shareholders.  Unless otherwise  provided by
law or by the articles of  incorporation,  once a quorum is present at a meeting
of  shareholders,  the  shareholders  represented  in  person or by proxy at the
meeting may conduct such business as may be properly  brought before the meeting
until it is adjourned,  and the  subsequent  withdrawal  from the meeting of any
shareholder or the refusal of any shareholder  represented in person or by proxy
to vote  shall  not  affect  the  presence  of a quorum at the  meeting.  Unless
otherwise provided by law or by the articles of incorporation,  the shareholders
represented in person or by proxy at a meeting of shareholders at which a quorum
is not present may adjourn the meeting  until such time and to such place as may
be determined  by a vote of the holders of a majority of the shares  represented
in person or by proxy at that meeting.  At any subsequent session of the meeting
at  which a  quorum  is  present  in  person  or by proxy  any  business  may be
transacted  which  could  have been  transacted  at the  initial  session of the
meeting if a quorum had been present.

9.       (a)  Proxies.  At any  meeting of the  shareholders  every  shareholder
having  the  right  to vote  shall be  entitled  to vote in  person  or by proxy
executed  in writing by such  shareholder.  A  telegram,  telex,  cablegram,  or
similar  transmission  by  the  shareholder,  or  a  photographic,  photostatic,
facsimile, or similar reproduction of a writing executed by a shareholder, shall
be treated as an  execution  in writing  for these  purposes.  No proxy shall be
valid after eleven (11) months from the date of its execution,  unless otherwise
provided  in the  proxy.  A proxy  shall be  revocable  unless  the  proxy  form
conspicuously states that the proxy is irrevocable and the proxy is coupled with
an interest.

         (b)  Voting.  Each  shareholder  shall  have one vote for each share of
stock entitled to vote under the provisions of the articles of incorporation and
which is  registered  in his name on the  books of the  corporation,  and in the
election of directors  shall have for each such share one vote for one candidate
for each directorship to be filled, cumulative voting not being permitted.

         No person  shall be admitted  to vote on any shares of the  corporation
belonging or hypothecated to the corporation.

         (c) Registered  Shareholders - Exceptions - Stock  Ownership  Presumed.
The  corporation  may regard  the person in whose name any shares  issued by the
corporation  are registered in the share transfer  records of the corporation at
any  particular  time as the owner of those  shares at that time for purposes of
voting those shares, receiving distributions thereon or
                                       4

notices in respect  thereof,  transferring  those shares,  exercising  rights of
dissent with respect to those shares, exercising or waiving any preemptive right
with respect to those  shares,  entering into  agreements  with respect to those
shares in  accordance  with  applicable  law, or giving  proxies with respect to
those shares,  and the term  "shareholder" as used in these bylaws means one who
is a holder  of shares  so  registered  in the  share  transfer  records  of the
corporation.

10. Shareholders' Lists. A complete list of the shareholders entitled to vote at
each  meeting of the  shareholders,  or any  adjournments  thereof,  arranged in
alphabetical  order, with the address of and the number of voting shares held by
each,  shall be prepared at least ten (10) days before each such  meeting by the
officer or agent of the corporation  having charge of the share transfer records
of the  corporation,  and,  for a period of ten (10) days prior to the  meeting,
shall be kept on file at the registered office or principal place of business of
the  corporation  and shall at any time during the usual  hours for  business be
subject to inspection by any shareholder.  Such list or a duplicate thereof also
shall 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.  Subject to the  provisions of Section 38 hereof,  the original list or
share  transfer  records  shall  be  prima  facie  evidence  as to who  are  the
shareholders  entitled to examine such share transfer  records or to vote at any
meeting of shareholders.

         Failure to comply with the  foregoing  shall not affect the validity of
any action taken at any such meeting.

                                    DIRECTORS

11.  Directors - Number.  Unless and until  changed by the board of directors as
hereinafter  provided,  the  number  of  directors  to  constitute  the board of
directors  shall be five (5).  Directors  need not be  residents of the state of
Texas or  shareholders  unless  the  articles  of  incorporation  at any time so
require.  The board of  directors  shall  have the power to change the number of
directors by resolution adopted by a majority of the whole board,  provided that
any notice required by law of any such change is duly given,  but no decrease in
the number of  directors  shall have the  effect of  shortening  the term of any
incumbent  director.  At each annual meeting of  shareholders  the  shareholders
shall elect directors to hold office until the next  succeeding  annual meeting.
Unless removed in accordance  with provisions of these bylaws or the articles of
incorporation,  each  director  shall  hold  office for the term for which he is
elected and until his successor shall have been elected and qualified.

         At any meeting of  shareholders  called  expressly for that purpose any
director or the entire board of directors may be removed, with or without cause,
by a vote of the holders of a majority of the shares then entitled to vote at an
election of directors,  subject to any further  restrictions on removal that may
be contained in these bylaws.

12.      (a)  Powers  of the  Board.  The  powers  of the  corporation  shall be
exercised  by or under the  authority  of, and the  business  and affairs of the
corporation  shall be managed  under the direction of, the board of directors of
the corporation,  acting as a board. The board shall have and is vested with all
and unlimited powers and authorities, except as may be expressly limited 
                                       5

by law, the articles of incorporation or these bylaws, to do or cause to be done
any and all lawful things for and on behalf of the  corporation,  to exercise or
cause to be exercised any or all of its powers,  privileges, and franchises, and
to seek the effectuation of its objects and purposes.

         (b) Interested Director Transactions. Unless otherwise provided by law,
the articles of  incorporation,  or these bylaws, no otherwise valid contract or
transaction  between  the  corporation  and  one or  more  of its  directors  or
officers,  or  between  the  corporation  and  any  other  domestic  or  foreign
corporation,  or other entity in which one or more of its  directors or officers
are  directors  or  officers  or  have a  financial  interest,  shall  be  valid
notwithstanding whether the director or officer is present at or participates in
the meeting of the board or committee  thereof which  authorizes the contract or
transaction,  or solely because his or their votes are counted for such purpose,
if any of the following is satisfied:

                  (1) The material facts as to his  relationship or interest and
         as to the  contract or  transaction  are  disclosed or are known to the
         board of directors or the committee, and the board or committee in good
         faith authorizes the contract or transaction by the affirmative vote of
         a  majority   of  the   disinterested   directors,   even   though  the
         disinterested directors be less than a quorum; or

                  (2) The material facts as to his  relationship or interest and
         as to the  contract or  transaction  are  disclosed or are known to the
         shareholders  entitled to vote thereon, and the contract or transaction
         is specifically approved in good faith by vote of the shareholders; or

                  (3) The contract or transaction is fair as to the  corporation
         as of the time it is authorized,  approved, or ratified by the board of
         directors, a committee thereof, or the shareholders.

         Common or  interested  directors  may be  counted  in  determining  the
presence  of a quorum at a meeting of the board of  directors  or of a committee
which authorizes the contract or transaction.

13. Offices.  The directors may have one or more offices,  and keep the books of
the corporation  (except share transfer records and such other books and records
as may by law be  required  to be kept at a  particular  place) at such place or
places  within or without the State of Texas as the board of directors  may from
time to time determine.

14. Acceptance of Election. Each director,  upon his election,  shall qualify by
accepting the office of director, and his attendance at, or his written approval
of the minutes of, any meeting of the  newly-elected  directors shall constitute
his acceptance of such office;  or he may execute such  acceptance by a separate
writing, which shall be placed in the minute book.

15. Regular Meetings - Notice. Regular meetings of the board may be held with or
without  notice at such times and places  either  within or without the State of
Texas as shall from time to
                                       6

time be fixed by resolution adopted by the full board of directors. Any business
may be transacted at a regular meeting.

16. Special  Meetings - Notice.  Special  meetings of the board may be called at
any time by the chairman of the board, the president, any vice president, or the
secretary,  or by any one or more of the  directors.  The place may be within or
without the State of Texas as designated in the notice.

         Written or printed notice of each special meeting of the board, stating
the place,  day, and hour of the meeting and to the extent,  if any, required by
the articles of incorporation or by law, the purpose or purposes thereof,  shall
be mailed to each  director  at least three (3) days before the day on which the
meeting is to be held, or shall be delivered to him personally or sent to him by
telegram  at least two (2) days  before  the day on which the  meeting  is to be
held.  If  mailed,  such  notice  shall be  deemed  to be  delivered  when it is
deposited in the United States mail with postage  thereon  prepaid and addressed
to the  director  at his  residence  or  usual  place of  business.  If given by
telegraph,  such notice shall be deemed to be delivered  when it is delivered to
the telegraph company, addressed to the director at his residence or usual place
of business as  indicated  on the records of the  corporation,  with the cost of
transmission prepaid. The notice may be given by any officer having authority to
call the meeting or by any director.

         "Notice" and "call" with respect to such meetings shall be deemed to be
synonymous.

17.  Waiver  of  Notice.  Whenever  any  notice is  required  to be given to any
director under the provisions of these bylaws, the articles of incorporation, or
of any law, a waiver thereof in writing signed by such director,  whether before
or after the time  stated  therein,  shall be  equivalent  to the giving of such
notice.  To the extent provided by law,  attendance of a director at any meeting
shall constitute a waiver of notice of such meeting.
                                       7

18.  Meetings  by  Conference  Telephone  or Similar  Communications  Equipment.
Subject to the requirements for notice of meetings,  unless otherwise restricted
by the articles of incorporation or these bylaws or by law, members of the board
of directors of the corporation,  or members of any committee  designated by the
board, may participate in and hold a meeting of such board or committee by means
of conference telephone or similar communications  equipment whereby all persons
participating in a meeting in this manner can hear each other, and participation
in a meeting in this manner shall constitute presence in person at such meeting,
except  when a person  participates  in a meeting  for the  express  purpose  of
objecting to the  transaction  of any business on the ground that the meeting is
not lawfully called or convened.

19. Action Without a Meeting. Any action which is required to be or may be taken
at a  meeting  of the  directors,  or of the  executive  committee  or any other
committee  of the  directors,  may be taken  without a meeting  if a consent  in
writing,  setting forth the action so taken,  is signed by all of the members of
the board or of the  committee,  as the case may be. Such consent shall have the
same force and effect as a unanimous  vote at a meeting duly held. The secretary
shall  file such  consents  with the  minutes  of the  meetings  of the board of
directors or of the committee as the case may be.

20.  Quorum.  At all  meetings  of the  board a  majority  of the full  board of
directors shall, unless a greater number as to any particular matter is required
by law, the articles of incorporation  or these bylaws,  constitute a quorum for
the transaction of business,  and the act of a majority of the directors present
at any  meeting  at  which  there  is a  quorum,  except  as  may  be  otherwise
specifically  provided by law, the articles of  incorporation  or these  bylaws,
shall be the act of the board of directors.

21. Vacancies.  Unless otherwise provided in the articles of incorporation or by
law,  vacancies on the board of directors may be filled by the affirmative  vote
of a majority of the remaining  directors,  although less than a quorum, or by a
sole  remaining  director,  or by  election  at an annual or special  meeting of
shareholders called for that purpose. A director elected to fill a vacancy shall
be elected for the unexpired term of his predecessor in office. Any directorship
to be filled by reason of an increase in the number of  directors  may be filled
by election at an annual meeting or at a special meeting of shareholders  called
for that purpose,  or by the board of directors for a term of office  continuing
only  until the next  election  of one or more  directors  by the  shareholders;
provided  that  the  board  of  directors  may  not  fill  more  than  two  such
directorships  during the period between any two successive  annual  meetings of
shareholders.  Notwithstanding the foregoing,  whenever the holders of any class
or  series  of  shares  are  entitled  to  elect  one or more  directors  by the
provisions of the articles of incorporation, any vacancies in such directorships
and any  newly  created  directorship  for such  class or series to be filled by
reason  of an  increase  in the  number of such  directors  may be filled by the
affirmative vote of a majority of the directors  elected by such class or series
then in office or by a sole remaining director so elected, or by the vote of the
holders of the outstanding shares of such class or series, and such directorship
shall not in any case be filled by the vote of the  remaining  directors  or the
holders of the outstanding  shares as a whole unless  otherwise  provided in the
articles of incorporation.
                                       8

22.  Indemnification  and Expenses;  Liability of Directors  and  Officers.  The
corporation  shall (i) indemnify  any person who is or was a director,  officer,
employee, or agent of the corporation,  or while a director,  officer, employee,
or agent of the corporation, 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, to the fullest extent that a corporation may or is required to grant
indemnification  to a director under the Texas Business  Corporation  Act as now
written or as  hereafter  amended,  and (ii) shall pay or  reimburse  reasonable
expenses (including court costs and attorneys' fees) incurred by any such person
who  was,  is,  or is  threatened  to be  named  defendant  or  respondent  in a
proceeding  (including any threatened,  pending,  or completed action,  suit, or
proceeding,   whether   civil,   criminal,   administrative,   arbitrative,   or
investigative,  any appeal in any such  action,  suit,  or  proceeding,  and any
inquiry  or  investigation  that  could  lead  to  such  an  action,   suit,  or
proceeding),  in  advance of the final  disposition  of the  proceeding,  to the
fullest extent that a corporation may or is required to advance such expenses to
a  director  under the  Texas  Business  Corporation  Act as now  written  or as
hereafter  amended.  The corporation  may indemnify and advance  expenses to any
person to such further extent as permitted by law.

         The  corporation  may purchase and maintain  insurance on behalf of any
person who holds or who has held any position named hereinabove as allowed under
the Texas Business Corporation Act, as now written or as hereafter amended.

         Except as otherwise provided by the Texas Business  Corporation Act, as
now written or as hereafter amended, with respect to directors and shareholders,
no person shall be liable to the corporation for any loss, damage, liability, or
expense  suffered by it on account of any action taken or omitted to be taken by
him as a  director  or officer of the  corporation  or of any other  corporation
which he serves as a director or officer at the request of the  corporation,  if
such  person (i)  exercised  the same  degree of care and skill as a prudent man
would have exercised under the  circumstances in the conduct of his own affairs,
or (ii) took or omitted to take such action in  reliance  upon advice of counsel
for the corporation,  or for such other corporation,  or upon statements made or
information  furnished  by  directors,  officers,  employees,  or  agents of the
corporation, or of such other corporation, which he had no reasonable grounds to
disbelieve.

23.  Executive and Other  Committees.  The board of directors,  by resolution or
resolutions adopted by a majority of the full board of directors,  may designate
from among its members an executive  committee and one or more other committees,
each  of  which  committees,  to the  extent  provided  in  said  resolution  or
resolutions,  shall  have and may  exercise  all the  authority  of the board of
directors in the management of the  corporation,  except to the extent expressly
prohibited by the Texas Business  Corporation Act; provided,  however,  that the
designation of any such committee and the delegation  thereto of authority shall
not operate to relieve the board of  directors,  or any member  thereof,  of any
responsibility imposed upon it or him by law.

         Each  committee  so  designated  shall  keep  regular  minutes  of  its
proceedings,  which  minutes  shall  be  recorded  in  the  minute  book  of the
corporation. The secretary or an assistant
                                        9

secretary of the corporation may act as secretary for any such committee if such
committee so requests.

24.  Compensation of Directors and Committee  Members.  Directors and members of
all  committees  shall not receive any stated salary for their services as such,
unless authorized by resolution of the board.  Also, by resolution of the board,
a fixed sum and expenses of attendance, if any, may be allowed for attendance at
each  regular or  special  meeting of the board of  directors  or any  committee
thereof. Nothing herein contained shall be construed to preclude any director or
committee  member  from  serving  the  corporation  in any  other  capacity  and
receiving compensation therefor.

                                    OFFICERS

25.      (a) Officers - Who Shall  Constitute.  The officers of the  corporation
shall  consist  of a  chairman  of the  board,  a  president,  one or more  vice
presidents, a secretary, a treasurer, one or more assistant secretaries, and one
or more assistant treasurers.  The board shall elect a president and a secretary
at its first meeting after each annual  meeting of the  shareholders.  The board
then, or from time to time,  also may elect one or more of the other  prescribed
officers as it shall deem advisable,  but need not elect any officers other than
a president  and a  secretary.  The board may,  if it desires,  elect or appoint
additional  officers as may be deemed  necessary,  and may  further  identify or
describe any one or more of the officers of the corporation.

         The  officers  of the  corporation  need not be members of the board of
directors. Any two or more offices may be held by the same person.

         An officer shall be deemed  qualified when he enters upon the duties of
the office to which he has been  elected or  appointed  and  furnishes  any bond
required by the board; but the board also may require his written acceptance and
promise faithfully to discharge the duties of such office.

         (b) Term of  Office.  Each  officer of the  corporation  shall hold his
office at the pleasure of the board of directors or for such other period as the
board may  specify  at the time of his  election  or  appointment,  or until his
death,  resignation,  or removal by the board,  whichever  first occurs.  In any
event,  each officer of the  corporation  who is not reelected or reappointed at
the annual  election of officers by the board next  succeeding  his  election or
appointment shall be deemed to have been removed by the board,  unless the board
provides otherwise at the time of his election or appointment.

         (c) Other  Agents.  The board from time to time also may  appoint  such
other agents for the  corporation as it shall deem necessary or advisable,  each
of whom shall serve at the pleasure of the board or for such period as the board
may specify,  and shall exercise such powers,  have such titles and perform such
duties as shall be  determined  from time to time by the board or by an  officer
empowered by the board to make such determinations.
                                       10

26. Removal.  Any officer or agent or member of a committee elected or appointed
by the board of directors, and any employee, may be removed or discharged by the
board  whenever in its judgment the best interests of the  corporation  would be
served thereby,  but such removal or discharge shall be without prejudice to the
contract  rights,  if any, of the person so removed or  discharged.  Election or
appointment of an officer or agent or member of a committee  shall not of itself
create contract rights.

27. Salaries and Compensation. Salaries and compensation of all elected officers
of the  corporation  shall be fixed,  increased,  or  decreased  by the board of
directors,  but this  power,  except  as to the  salary or  compensation  of the
chairman  of the board  and the  president,  unless  prohibited  by law,  may be
delegated  by the  board to the  chairman  of the  board,  the  president,  or a
committee.  Salaries and compensation of all appointed  officers and agents, and
of all employees of the corporation,  may be fixed,  increased,  or decreased by
the board of  directors,  but until action is taken with respect  thereto by the
board of  directors,  the same  may be  fixed,  increased  or  decreased  by the
president or by such other  officer or officers as may be empowered by the board
of directors to do so.

28. Delegation of Authority to Hire, Discharge,  and Designate Duties. The board
from time to time may  delegate to the chairman of the board,  the  president or
other  officer or  executive  employee of the  corporation,  authority  to hire,
discharge, fix, and modify the duties, salary or other compensation of employees
of the corporation under their jurisdiction,  and the board may delegate to such
officer or executive  employee  similar  authority with respect to obtaining and
retaining for the corporation the services of attorneys,  accountants, and other
experts.

29. The Chairman of the Board. If a chairman of the board be elected,  he shall,
except as otherwise provided for in Section 6(c) of these bylaws, preside at all
meetings of the  shareholders and directors at which he may be present and shall
have such other duties,  powers, and authority as may be prescribed elsewhere in
these  bylaws.  The board of directors  may delegate  such other  authority  and
assign such  additional  duties to the  chairman of the board,  other than those
conferred by law  exclusively  upon the  president,  as it may from time to time
determine,  and, to the extent  permissible  by law, the board may designate the
chairman of the board as the chief executive officer of the corporation with all
of the powers  otherwise  conferred upon the president of the corporation  under
Section  30 of  these  bylaws,  or  it  may,  from  time  to  time,  divide  the
responsibilities,  duties,  and authority for the general control and management
of the corporation's  business and affairs between the chairman of the board and
the president. If the chairman of the board is designated as the chief executive
officer of the  corporation,  notice thereof shall be given to the extent and in
the manner as may be required by law.

30. The President.  Unless the board otherwise provides,  the president shall be
the chief  executive  officer of the  corporation  with such  general  executive
powers and duties of  supervision  and  management  as usually are vested in the
office of the chief executive officer of a corporation,  and he shall carry into
effect all directions and resolutions of the board. Except as otherwise provided
for in  Section  6(c) of these  bylaws,  the  president,  in the  absence of the
chairman of the board or if there be no chairman of the board,  shall preside at
all meetings of the shareholders and directors.
                                       11

         The president may execute all bonds, notes, debentures,  mortgages, and
other contracts  requiring a seal, under the seal of the corporation,  may cause
the seal to be affixed thereto, and may execute all other instruments for and in
the name of the corporation.

         Unless  the board  otherwise  provides,  the  president,  or any person
designated in writing by him, may (i) attend  meetings of  shareholders of other
corporations  to represent this  corporation  thereat and to vote or take action
with respect to the shares of any such corporation  owned by this corporation in
such manner as he or his  designee may  determine,  and (ii) execute and deliver
waivers  of notice  and  proxies  for and in the name of this  corporation  with
respect to shares of any such corporation owned by this corporation.

         He shall, unless the board otherwise provides,  be an ex officio member
of all standing committees.

         He shall  have such other or further  duties  and  authority  as may be
prescribed  elsewhere  in  these  bylaws  or from  time to time by the  board of
directors.

         If a  chairman  of the board be  elected  and  designated  as the chief
executive officer of the corporation, as provided in Section 29 of these bylaws,
the president shall perform such duties as may be specifically  delegated to him
by the board of directors or are conferred by law  exclusively  upon him, and in
the absence,  disability,  or inability or refusal to act of the chairman of the
board,  the  president  shall  perform the duties and exercise the powers of the
chairman of the board.

31. Vice Presidents. In the absence,  disability, or inability or refusal to act
of the  president,  any vice  president  may perform the duties and exercise the
powers of the president,  until the board  otherwise  provides.  Vice presidents
shall perform such other duties as the board shall from time to time prescribe.

32. The  Secretary  and Assistant  Secretaries.  The secretary  shall attend all
sessions of the board and,  except as otherwise  provided for in Section 6(c) of
these bylaws,  all meetings of the  shareholders,  shall prepare  minutes of all
proceedings  at such  meetings,  and shall preserve them in a minute book of the
corporation.  He shall  perform  similar  duties  for the  executive  and  other
standing committees when requested by the board or any such committee.

         He shall  see that all  books,  records,  lists,  and  information,  or
duplicates,  required to be maintained at the  registered or other office of the
corporation in Texas, or elsewhere, are so maintained.

         He shall keep in safe  custody the seal of the  corporation  and,  when
duly authorized to do so, shall affix it to any instrument requiring a corporate
seal, and, when so affixed, he shall attest the seal by his signature.
                                       12

         He shall  perform such other duties and have such other  responsibility
and  authority  as may be  prescribed  elsewhere in these bylaws or from time to
time  by  the  board  of  directors  or  the  chief  executive  officer  of  the
corporation, under whose direct supervision he shall be.

         He shall have the general duties,  powers,  and  responsibilities  of a
secretary of a corporation.

         Any assistant secretary,  in the absence,  disability,  or inability or
refusal to act of the secretary,  may perform the duties and exercise the powers
of the secretary until the board otherwise provides. Assistant secretaries shall
perform  such other  duties and have such other  authority as the board may from
time to time prescribe.

33.  The  Treasurer  and  Assistant   Treasurers.   The  treasurer   shall  have
responsibility   for  the  safekeeping  of  the  funds  and  securities  of  the
corporation,  shall  keep or cause  to be kept  full and  accurate  accounts  of
receipts and  disbursements  in books  belonging to the  corporation,  and shall
keep, or cause to be kept, all other books of account and accounting  records of
the corporation.  He shall deposit or cause to be deposited all moneys and other
valuable  effects  in the  name and to the  credit  of the  corporation  in such
depositories as may be designated by the board of directors or by any officer of
the corporation to whom such authority has been granted by the board.

         He  shall  disburse,  or  permit  to be  disbursed,  the  funds  of the
corporation as may be ordered, or authorized generally,  by the board, and shall
render to the chief  executive  officer of the  corporation  and the  directors,
whenever  they may require it, an account of all his  transactions  as treasurer
and of those  under his  jurisdiction,  and of the  financial  condition  of the
corporation.

         He  shall   perform  such  other  duties  and  shall  have  such  other
responsibility  and authority as may be prescribed  elsewhere in these bylaws or
from time to time by the board of directors.

         He shall have the  general  duties,  powers,  and  responsibility  of a
treasurer of a corporation,  and shall,  unless otherwise provided by the board,
be the chief financial and accounting officer of the corporation.

         If required by the board, he shall give the corporation a bond in a sum
and  with  one or more  sureties  satisfactory  to the  board  for the  faithful
performance  of  the  duties  of his  office  and  for  the  restoration  to the
corporation, in the case of his death, resignation,  retirement, or removal from
office, of all books,  papers,  vouchers,  money, and other property of whatever
kind in his possession or under his control which belong to the corporation.

         Any assistant treasurer,  in the absence,  disability,  or inability or
refusal to act of the treasurer,  may perform the duties and exercise the powers
of the treasurer until the board otherwise provides.  Assistant treasurers shall
perform  such other  duties and have such other  authority as the board may from
time to time prescribe.
                                       13

34. Duties of Officers May Be Delegated.  If any officer of the  corporation  be
absent  or  unable  to act,  or for any  other  reason  that the  board may deem
sufficient,  the  board may  delegate,  for the time  being,  some or all of the
functions,  duties,  powers,  and  responsibilities  of any officer to any other
officer,  or to any  other  agent  or  employee  of  the  corporation  or  other
responsible person, provided a majority of the whole board of directors concurs.

                                 SHARES OF STOCK

35. Payment for Shares of Stock.  The board of directors may authorize shares to
be issued for consideration  consisting of any tangible or intangible benefit to
the  corporation  or other  property  of any  kind or  nature,  including  cash,
promissory notes,  services  performed,  contracts for services to be performed,
other  securities of the  corporation,  or securities of any other  corporation,
domestic or foreign, or other entity. In addition, shares may be issued pursuant
to a  plan  of  conversion  or  plan  of  merger  in the  manner  and  for  such
consideration  as may be  provided  for in the  plan  of  conversion  or plan of
merger.  Shares may not be issued  until the full  amount of the  consideration,
fixed as provided by law, has been paid or  delivered as required in  connection
with the authorization of the shares. When such consideration shall have been so
paid or  delivered,  the  shares  shall be deemed to have  been  issued  and the
subscriber or shareholder  entitled to receive such issue shall be a shareholder
with respect to such shares,  and the shares shall be considered  fully paid and
non-assessable.

36. Certificates for Shares of Stock. The corporation shall deliver certificates
representing  shares to which  shareholders  are entitled.  The certificates for
shares of stock of the  corporation  shall be numbered and shall be in such form
as may be  prescribed  by the board of  directors  in  conformity  with law. The
issuance  of shares  shall be  entered  in the  share  transfer  records  of the
corporation as they are issued.  Such entries shall show the name and address of
the  person,  firm,  partnership,  corporation,  or  association  to  whom  each
certificate is issued. Each certificate shall state upon the face thereof:  that
the  corporation is organized  under the laws of Texas,  the name of the person,
firm, partnership,  corporation, or association to whom it is issued, the number
of shares  represented  thereby,  and the par value of each share represented by
such certificate, or a statement that such shares are without value. It shall be
signed by an officer of the corporation,  and may be sealed with the seal of the
corporation,  which  signature and seal may be facsimiles.  In case such officer
who  has  signed  or  whose  facsimile  signature  has  been  placed  upon  such
certificate  shall have ceased to be such  officer  before such  certificate  is
issued,  it may be issued  by the  corporation  with the same  effect as if such
officer were such officer at the date of its issuance.

37.  Transfers of Shares - Transfer  Agent -  Registrar.  Transfers of shares of
stock shall be made in the share transfer records of the corporation only by the
person named in the stock certificate,  or by his attorney lawfully  constituted
in writing, and upon surrender of the certificate  therefor.  The share transfer
records shall be in the  possession of the secretary or of a transfer  agent for
the corporation.  The corporation,  by resolution of the board, may from time to
time  appoint a  transfer  agent  and,  if  desired,  a  registrar,  under  such
arrangements  and upon such terms and  conditions as the board deems  advisable,
but until and unless the board appoints some other person,  firm, or corporation
as its transfer agent (and upon the revocation of any such
                                       14

appointment,  thereafter  until  a  new  appointment  is  similarly  made),  the
secretary  of the  corporation  shall be the transfer  agent of the  corporation
without the necessity of any formal action of the board,  and the secretary,  or
any person designated by him, shall perform all of the duties thereof.

38.      (a) Fixing  Record  Dates for  Meetings,  Distributions,  Etc.  For the
purpose  of  determining  shareholders  entitled  to notice of or to vote at any
meeting of shareholders or any adjournment  thereof,  or entitled to receive any
distribution or dividend (other than a purchase or redemption by the corporation
of any of its own shares) or share dividend, or in order to make a determination
of   shareholders   for  any  other  proper  purpose  (other  than   determining
shareholders  entitled to consent to action by shareholders proposed to be taken
without a meeting of  shareholders),  the board of directors of the  corporation
may provide that the share transfer records shall be closed for a stated period,
which shall not exceed sixty (60) days. If the share  transfer  records shall be
closed for the purpose of determining  shareholders  entitled to notice of or to
vote at a meeting of shareholders, such records shall be closed for at least ten
(10) days  immediately  preceding  such  meeting.  In lieu of closing  the share
transfer records, the board of directors may fix in advance a date as the record
date for any such determination of shareholders, such date in any case to be not
more than sixty (60) days and,  in the case of a meeting  of  shareholders,  not
less  than ten (10)  days  prior to the  date on  which  the  particular  action
requiring  such  determination  of  shareholders  is to be  taken.  If the share
transfer  records  are not  closed  and no record  date is fixed by the board of
directors for the determination of shareholders entitled to notice of or to vote
at a meeting of shareholders, or shareholders entitled to receive a distribution
or dividend  (other than a repurchase or redemption by the corporation of any of
its own  shares),  the date on which notice of the meeting is mailed or the date
on which the resolution of the board of directors declaring such distribution or
dividend  is  adopted,  as the case may be,  shall be the  record  date for such
determination of shareholders.  When a determination of shareholders entitled to
vote at any  meeting  of  shareholders  has been made as herein  provided,  such
determination  shall  apply  to  any  adjournment  thereof,   except  where  the
determination  has been made through the closing of share  transfer  records and
the stated period of closing has expired.
                                       15

         (b) Fixing  Record Dates for  Consents to Action.  Unless a record date
shall  have  previously  been  fixed or  determined  pursuant  to this  section,
whenever  action by  shareholders  is proposed to be taken by consent in writing
without a meeting of shareholders,  the board of directors may fix a record date
for the purpose of determining  shareholders entitled to consent to that action,
which  record date shall not  precede,  and shall not be more than ten (10) days
after,  the date upon which the resolution  fixing the record date is adopted by
the  board of  directors.  If no  record  date has  been  fixed by the  board of
directors and the prior action of the board of directors is not required by law,
the record date for  determining  shareholders  entitled to consent to action in
writing  without a meeting  shall be the  first  date on which a signed  written
consent  setting  forth the action taken or proposed to be taken is delivered to
the  corporation by delivery to its registered  office,  its principal  place of
business,  or an officer or an agent of the  corporation  having  custody of the
books in which  proceedings of meetings of shareholders  are recorded.  Delivery
shall be by hand or by certified or registered mail,  return receipt  requested.
Delivery to the corporation's  principal place of business shall be addressed to
the  president or the  principal  executive  officer of the  corporation.  If no
record date shall have been fixed by the board of directors  and prior action of
the board of  directors  is  required by law,  the record  date for  determining
shareholders entitled to consent to action in writing without a meeting shall be
at the close of  business on the date on which the board of  directors  adopts a
resolution taking such prior action.

39. Lost, Destroyed, or Stolen Certificates. The board of directors may direct a
new  certificate  to be  issued  in  lieu  of  any  theretofore  issued  by  the
corporation that is alleged to have been lost,  destroyed,  or wrongfully taken,
if before  the  corporation  has  notice  that the  shares  represented  by such
certificate  have  been  acquired  by a bona fide  purchaser,  the owner of such
shares   submits  to  the   corporation  an  affidavit  in  form  and  substance
satisfactory to the corporation's counsel, of the fact of loss, destruction,  or
wrongful  taking by the  person  alleging  the  certificate  to have been  lost,
destroyed,  or  wrongfully  taken.  When  authorizing  such  issuance  of a  new
certificate,  the  board of  directors,  in its  discretion  and as a  condition
precedent  to the  issuance  thereof,  may  require  the  owner  of  such  lost,
destroyed, or wrongfully taken certificate, or his legal representative, to give
the  corporation a bond in such sum and form,  and with such surety or sureties,
as it may direct as  indemnity  against  any claim that may be made  against the
corporation  with  respect  to  the  certificate  alleged  to  have  been  lost,
destroyed, or wrongfully taken, or may require both such conditions or any other
reasonable conditions or requirements; provided, however, that a new certificate
may be issued  without  requiring a bond when in the judgment of the board it is
proper to do so.

40.  Regulations.  The board of directors shall have power and authority to make
all such rules and  regulations as it may deem  expedient  concerning the issue,
transfer,  conversion,  and  registration of certificates for shares of stock of
