                     ARTICLE ONE - CORPORATE CHARTER AND BYLAWS


1.01 CORPORATE CHARTER PROVISIONS

     The Corporation's Charter authorizes One Hundred Thousand (100,000) shares
to be issued.  The Officers and transfer agents issuing shares of the
Corporation shall not exceed this matter.  Such officers and agents shall advise
the Board at least annually of the authorized shares remaining available to be
issued.  No shares shall be issued for less than par value stated in the
Articles of Incorporation.  Each Charter provision shall be observed until
amended by Restated Articles or Articles of Amendment duly filed with the
Secretary of State.

1.02 REGISTERED AGENT OR OFFICE - REQUIREMENT OF FILING CHANGES WITH SECRETARY
OF STATE

     The address of the Registered Office provided in the initial Articles of
Incorporation, as duly placed of record with the Secretary of State for the
State of Texas is 444 East Medical Center Blvd. #411 Webster, Texas 77598-4339. 

     The name of the Registered Agent of the Corporation at such address, as
duly set forth in its initial Articles of Incorporation, is MICHAEL L. COOPER.

     The Registered Agent or Office may be changed by filing appropriate
documents with the Secretary of State, and not otherwise.  Such filing shall be
made promptly with each change.  Arrangements for each change in Registered
Agent or Office shall ensure that the corporation is not exposed to the
possibility of a default judgment.  Each successive Registered Agent shall be of
reliable character and well informed of the necessity of immediately furnishing
the papers of any lawsuit against the corporation to its attorneys. 

1.03 INITIAL BUSINESS OFFICE

     The address of the initial principal business office of the Corporation is
hereby established to be 10913 Metronome Houston, Texas 77043.

Corporation may require.

<PAGE>

1.04 AMENDMENT OF BYLAWS

     The Board of Directors may alter, amend, or repeal these Bylaws, and adopt
new Bylaws.  All such Bylaw changes shall take effect upon adoption by the
Directors, subject to repeal or change by the shareholders.  Notice of Bylaws
changes shall be given in or before notice of the Shareholders' Meeting
following their adoption.


                  ARTICLE TWO - DIRECTORS AND DIRECTORS' MEETINGS


2.01 ACTION BY CONSENT OF BOARD WITHOUT MEETING

     Any action required or permitted to be taken by the Board of Directors may
be taken without a meeting, and shall have the same force and effect as a
unanimous vote of Directors, if all members of the Board consent in writing to
the action.  Such consent may be given individually or collectively.

2.02 TELEPHONE MEETINGS

     Subject to the notice provisions required by these Bylaws and by the
Business Corporation Act, Directors of the Corporation may participate in and
hold a meeting by means of conference call or similar communication by which all
persons participating can hear each other.  Participation in such a meeting
shall constitute presence in person at such meeting, except participation for
the express purpose of objecting to the transaction of any business on the
ground that the meeting is not lawfully called or convened.

2.03 PLACE OF MEETING

     Meetings of the Board of Directors shall be held at the business office of
the Corporation or at such other place within or without the State of Texas as
may be designated by the Board.

2.04 REGULAR MEETINGS

     Regular meetings of the Board of Directors shall be held, without call or
notice, immediately following each annual meeting of the Shareholders of this
Corporation, and at such other regular times as the Directors may determine.

-------------------------------------------------------------------------------

                                BYLAWS, PAGE 5

<PAGE>

2.05 CALL OF SPECIAL MEETING

     Special meetings of the Board of Directors for any purpose may be called at
any time by the President or, if the President is absent or unable or refuses to
act, by any Vice President or any two Directors.  Written notices of the special
meetings, stating the time and place of the meeting, shall be mailed ten days
before, or telegraphed or personally delivered so as to be received by each
Director not later than two days before, the day appointed for the meeting. 
Notice of meetings need not indicate an agenda.  Generally a tentative agenda
will be included, but the meeting shall not be confined to any agenda included
with the notice.

     Meetings provided in these Bylaws shall not be invalid for lack of notice
if all persons entitled to notice are present at the meeting in person or by
proxy and do not object to the notice given; or if such persons consent to the
meeting in writing.

     Upon receiving notice, the Secretary or other officer sending notice shall
sign and file in the Corporate Record Book a statement of the details of giving
notice to each Director.  If such statement should later not be found in the
Corporate Record Book, due notice shall be presumed.

2.06 QUORUM

     The presence at any Directors' Meeting of a majority of the authorized
number of Directors shall be necessary to constitute a quorum to transact any
business, except to adjourn.  If a quorum is present, every act done or
resolution passed by a majority of the Directors present shall be the act of the
Board of Directors.  

2.07 ADJOURNMENT - NOTICE OF ADJOURNED MEETINGS

     A quorum of the Directors may adjourn any Directors' meeting to meet again
at a stated hour on a stated day.  Notice of the time and place where an
adjourned meeting will be held need not be given to absent Directors if the time
and place is fixed at the adjourned meeting.  In the absence of a quorum, a
majority of the Directors present may adjourn to a set time and place if notice
is duly given to the absent members, or until the time of the next regular
meeting of the Board.

2.08 CONDUCT OF MEETINGS

     At every meeting of the Board of Directors, the Chairman of the Board of
Directors, if there is such an officer, and if not, the President, or in the
President's absence, a Vice President designated by the President, or in the
absence of such designation, a Chairman chosen by a majority of the Directors
present, shall preside.  The Secretary of the Corporation shall act as 

-------------------------------------------------------------------------------

                                BYLAWS, PAGE 6

<PAGE>

Secretary of the Board of Directors.  When the Secretary is absent from any 
meeting, the Chairman may appoint any person to act as Secretary of that 
meeting.

2.09 POWERS OF THE BOARD OF DIRECTORS

     The business and affairs of the Corporation and all corporate powers shall
be exercised by or under authority of the Board of Directors, subject to
limitations imposed by law, the Articles of Incorporation, any applicable close
corporation shareholders' agreement, or by these Bylaws.

2.10 BOARD COMMITTEES - AUTHORITY TO APPOINT

     The Board of Directors may designate an executive committee and one or more
other committees to conduct business and affairs of the Corporation, to the
extent authorized by the resolution.  The Board shall have the power at any time
to change the powers and membership of any committee, fill vacancies, and
dissolve any committee.  Members of any committee shall receive such
compensation as the Board of Directors may from time to time provide.  The
designation of any committee and the delegation of authority thereto shall not
operate to relieve the Board of Directors, or of any member thereof, of any
responsibility imposed by law.

2.11 TRANSACTIONS WITH INTERESTED DIRECTORS

     Any contract or other transaction between the Corporation and any of its
Directors (or any corporation or firm in which any of its Directors are directly
or indirectly interested) shall be valid for all purposes notwithstanding the
presence of that Director at the meeting during which the contract or
transaction was authorized, and notwithstanding the Director's participation in
that meeting.  This section shall apply only if the contract or transaction is
just and reasonable to the Corporation at the time it is authorized and
ratified, the interest of each Director is known or disclosed to the Board of
Directors, and the Board nevertheless authorizes or ratifies the contract or
transaction by a majority of the disinterested Directors present.  Each
interested Director is to be counted in determining whether a quorum is present,
but shall not vote and shall not be counted in calculating the majority
necessary to carry the vote.  This section shall not be construed to invalidate
contracts or transactions that would be valid in its absence.


-------------------------------------------------------------------------------

                                BYLAWS, PAGE 7

<PAGE>

2.12 NUMBER OF DIRECTORS

     The number of Directors of this Corporation shall be one (1).  No Director
need be a Shareholder or a resident of Texas.  The number of Directors may be
increased or decreased from time to time by amendment of these Bylaws.  Any
decrease in the number of Directors shall not have the effect of shortening the
tenure which any incumbent Director would otherwise enjoy.

2.13 TERM OF OFFICE

     Directors shall be entitled to hold office until their successors are
elected and qualified.  Election of Directors shall occur at each annual meeting
of the Shareholders and may be held at any special meeting of Shareholders
called specifically for that purpose.

2.14 REMOVAL FROM DIRECTORS

     The entire Board of Directors or any individual Director may be removed
from office by a vote of Shareholders holding a majority of the outstanding
shares entitled to vote at an election of Directors.  However, if less than the
entire Board is to be removed, no one of the Directors may be removed if the
votes cast against his removal would be sufficient to elect him if then
cumulatively voted at an election of the entire Board of Directors.  No director
may be so removed except at an election of the class of Directors of which he is
a part.  If any or all Directors are so removed, new Directors may be elected at
the same meeting.  Whenever a class or series of shares is entitled to elect one
or more Directors under authority granted by the Articles of Incorporation, the
provisions of this Paragraph apply to the vote of that class or series and not
to the vote of the outstanding shares as a whole.

2.15 VACANCIES

     Vacancies on the Board of Directors shall exist upon the occurrence of any
of the following events:  (a) the death, resignation, or removal of any
Director; (b) an increase in the authorized number of Directors; or (c) the
failure of the Shareholders to elect the full authorized number of Directors to
be voted for at any annual, regular, or special Shareholders' meeting at which
any Director is to be elected.

     2.15(a)   DECLARATION OF VACANCY

     The Board of Directors may declare vacant the office of a Director if the
Director is adjudged incompetent by a court order, is convicted of a crime
involving moral turpitude, or fails to accept the office of Director, in writing
or by attending a meeting of the Board of Directors, within thirty (30) days of
notice of election.

-------------------------------------------------------------------------------

                                BYLAWS, PAGE 8

<PAGE>

     2.15(b)   FILLING VACANCIES BY DIRECTORS

     Vacancies other than those caused by an increase in the number of Directors
may be filled by a majority vote of the remaining Directors, though less than a
quorum, or by a sole remaining Director.  Each Director so elected shall hold
office until a qualified successor is elected at a Meeting of the Shareholders.

     2.15(c)   FILLING VACANCIES BY SHAREHOLDERS

     Any vacancy caused by an increase in the number of Directors shall be
filled by the Shareholders at an annual meeting or at a special meeting called
for that purpose.  The Shareholders may also elect a Director at any time to
fill any vacancy not filled by the Directors.  Upon the resignation of a
Director tendered to take effect at a future time, the Board or the Shareholders
may elect a successor to take office when the resignation becomes effective.

2.16 COMPENSATION

     Directors shall receive such compensation for their services as Directors
as shall be determined from time to time by resolution of the Board.  Any
Director may serve the Corporation in any other capacity as an officer, agent,
employee, or otherwise, and receive compensation therefor.

2.17 INDEMNIFICATION OF DIRECTORS AND OFFICERS

     The Board of Directors shall authorize the Corporation to pay or reimburse
any present or former Director or officer of the Corporation any costs or
expenses actually and necessarily incurred by that officer in any action, suit,
or proceeding to which the officer is made a party by reason of holding that
position, provided, however, that no officer shall receive such indemnification
if finally adjudicated therein to be liable for negligence or misconduct in
office.  This indemnification shall extend to good-faith expenditures incurred
in anticipation of threatened or proposed litigation.  The Board of Directors
may, in proper cases, extend the indemnification to cover the good-faith
settlement of any such action, suit, or proceeding, whether formally instituted
or not.

2.18 INSURING DIRECTORS, OFFICERS, AND EMPLOYEES

     The Corporation may purchase and maintain insurance on behalf of any
Director, officer, employee, or agent of the Corporation, or on behalf of any
person 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 that person and
incurred by that person in any such corporation, whether or not the Corporation
has the power to indemnify that person against liability for any of those acts.


                       ARTICLE THREE - SHAREHOLDERS' MEETINGS

3.02 TELEPHONE MEETINGS

Business Corporation Act, Shareholders of the Corporation may participate in and
hold a meeting by means of conference call or similar communication by which all

ground that the meeting is not lawfully called or convened.

3.03 PLACE OF MEETINGS

purposes for which the meeting is called.  Such written notice may be given 
personally, by mail, or other means.  Such notice shall be addressed to each 
recipient at such address as appears on the Books of the Corporation or was 
given by the recipient to the Corporation for the purpose of notice.  Any 
meeting provided herein shall not be invalid for lack of notice if consent to 
the meeting is given in writing by all persons entitled to vote at the 
meeting and is filed with the Secretary of the Corporation.  Such consent may 
be given either before or after the meeting.  Notice of the reconvening of an 
adjourned meetings is not necessary unless the meeting is adjourned more than 
thirty days past the date stated in the notice in which care notice of the 
adjourned meeting shall be given as in the case of any special meeting.  
Notice may be waived by a written waiver signed either before or after the 
meeting by the person entitled to the notice.

agent having charge of the stock transfer books for shares of the Corporation

the meeting, to the inspection of any Shareholder.  The original share transfer
books shall be PRIMA FACIE evidence as to the Shareholders entitled to examine

failure to prepare and to make the list available in the manner provided above
shall not affect the validity of any action taken at the meeting.  

3.06 VOTES PER SHARE

     Each outstanding share, regardless of class, shall be entitled to one (1)

the extent that the voting rights of the shares of any class or classes are

Shareholder shall have given written notice of his or her intention to do so to

provided above, all Shareholders may cumulate their votes.

3.08 PROXIES
