or as the business of the corporation may require.


                               ARTICLE 2:  SHAREHOLDERS

    2.01   Place of Meetings.  Meetings of shareholders shall be held at the
time and place, in or out of the State of Texas, as stated in any notice of a
meeting or in a waiver of such notice.

shareholders, a complete list of shareholders entitled to vote at the meeting,
arranged in alphabetical order, with the address of each and the number of
voting shares held by each, shall be prepared by the officer or agent having

prior to the meeting, shall be kept on file at the registered office or
principal place of business of the corporation and shall be subject to
inspection by any shareholder at any time during usual business hours.  The 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.

    2.04   Special Meetings.  Special meetings of the shareholders, unless
otherwise prescribed by statute, the articles of incorporation, or these bylaws,
may be called by the president, the board of directors, or the holders of not 
less than the percentage of all the shares entitled to vote at the meeting as
required by law to call such a meeting.  Business transacted at a special
meeting shall be confined to the purpose or purposes stated in the notice of
such meeting.

    2.05   Notice of Meetings.  Written or printed notice stating the place,
day and hour of a meeting and, in case of a special meeting, the purpose or
purposes for which such meeting is called, shall be delivered not less than ten
(10) nor more than sixty (60) days before the date of the meeting, either
personally or by mail, by or at the direction of the president, the secretary,
or the officer or person calling the meeting, to each shareholder entitled to
vote at the meeting.  If mailed, such notice shall be deemed to be delivered
when deposited in the United States mail addressed to the shareholder at his
address as it appears on the stock transfer records of the corporation, with
postage thereon prepaid.

    2.06   Quorum.  Unless otherwise provided for in the articles of
incorporation, the holders of a majority of the shares issued and outstanding
and entitled to vote at a meeting of the shareholders, present in person or
represented by proxy, shall be the requisite number of such shareholders and
shall constitute a quorum for the transaction of business.  Unless otherwise
provided in the articles of incorporation or these bylaws, 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 in the articles of incorporation or these
bylaws, the shareholders represented in person or by proxy at a meeting of
shareholders at which a quorum is not present may adjourn such 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 such meeting.

    2.07   Vote Required.  With respect to any matter, other than the election
of directors or a matter for which the affirmative vote of the holders of a
specified portion of the shares entitled 


                                          2



to vote is required by statute, the affirmative vote of the holders of a
majority of the shares entitled to vote on any such matter and represented in
person or by proxy at a meeting of shareholders at which a quorum is present
shall be the act of the shareholders.

    2.08   Method of Voting.  Except as otherwise provided in the articles of
incorporation, each outstanding share, regardless of class, shall be entitled to
one vote on each  matter submitted to a vote at a meeting of shareholders.  At
any meeting of the shareholders, any shareholder having the right to vote may
vote either in person or by proxy executed in writing by the shareholder.  A
telegram, telex cablegram, or similar transmission by the shareholder, or a
photographic, photostatic, facsimile, or similar reproduction of a writing
executed by the shareholder, shall be treated as an execution in writing.  No
proxy shall be valid after eleven (11) months from the date of its execution,
unless otherwise provided in such proxy.  Each proxy shall be revocable unless
the proxy form conspicuously states that the proxy is irrevocable and the proxy
is coupled with an interest as provided by applicable law.  Each proxy shall be
filed with the secretary of the corporation prior to or at the time of the
meeting.  Voting for directors shall be in accordance with Section 3.06 of these
bylaws.  Any vote may be taken by voice or by show of hands unless someone
entitled to vote objects, in which case written ballots shall be used.

    2.09   Record Date; Closing Transfer Books.  The board of directors may fix
in advance a record date for the purpose of determining shareholders entitled to
notice of, or to vote at, a meeting of the shareholders or any reconvening
thereof, or entitled to receive a distribution by the corporation or a share
dividend, or in order to make a determination of shareholders for any other
proper purpose, the record date to be not less than ten (10) nor more than sixty
(60) days prior to the meeting; or the board of directors may close the stock
transfer records for such purpose for a period of not less than ten (10) nor
more than sixty (60) days prior to such meeting.  In the absence of any action
by the board of directors, the date upon which the notice of the meeting is
mailed, or the date on which the resolution of the board of directors declaring
such distribution or share dividend is declared, shall be the record date.

    2.10   Order of Business at Meetings.  The order of business at all
meetings of shareholders shall be as determined by the chairman 


                                          3



of the meeting, but the order of business to be followed at any meeting, other
than a special meeting, at which a quorum is present may be changed by a
majority of the votes cast at such meeting by the shareholders present in person
or represented by proxy and entitled to vote at the meeting.  With respect to
special meetings, only business within the purpose or purposes described in the
notice of the special meeting may be conducted at a special meeting of the
shareholders.


                                ARTICLE 3:  DIRECTORS

    3.01   Management.  The business and affairs of the corporation shall be
managed under the direction of the  board of directors[who may exercise all such
powers of the corporation and do all such lawful acts and things as are not (by
statute or by the articles of incorporation or by these bylaws) directed or
required to be exercised or done by the shareholders.

    3.02   Number; Qualification; Election; Term.  The board of directors shall
consist of not less than one (1) nor more than [             ] directors, and
within that maximum and minimum shall be such number as shall be from time to
time specified by resolution of the board of directors; provided, however, no
director's term shall be shortened by reason of a resolution reducing the number
of directors; and further provided that the number of directors constituting the
initial board of directors shall be as provided in the articles of incorporation
and shall remain at such number unless and until changed by resolution of the
board of directors.  The directors shall be elected at the annual meeting of the
shareholders, except as provided in Sections 3.03 and 3.05 hereof.  Each
director elected shall hold office until his successor shall be elected and
shall qualify.

    3.03   Change in Number.  The number of directors may be increased or
decreased from time to time by amendment to these bylaws but no decrease shall
have the effect of shortening the term of any incumbent director.  Any
directorship to be filled by reason of an increase in the number of directors
may be filled by the board of directors for a term of office continuing only
until the election of one or more directors by the shareholders or may be filled
by election at an annual meeting or at a special meeting of shareholders called
for that purpose; provided, however, the board of directors may fill no more
than two such directorships during 


                                          4



the period between any two annual meetings of shareholders.  Notwithstanding the
provisions of this Section 3.03 to the contrary, 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 directorships of 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
directorships 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.

    3.04   Removal.  Any director may be removed either for or without cause at
any special or annual meeting of shareholders, by the affirmative vote of a
majority in number of shares of the shareholders present, in person or by
proxy,  at such meeting and entitled to vote for the election of such director
if notice of intention to act upon such matter shall have been given in the
notice calling such meeting.  

    3.05   Vacancies.  Subject to the provisions of Section 3.03 and 3.04, any
vacancy occurring in the board of directors (by death, resignation, removal or
otherwise) may be filled by the affirmative vote of a majority of the remaining
directors though less than a quorum of the board of directors.  A director
elected to fill a vacancy shall be elected for the unexpired term of his
predecessor in office.

    3.06   Election of Directors.  Unless otherwise provided in the articles of
incorporation, directors shall be elected by a plurality of the votes cast by
the holders of shares entitled to vote in the election of directors at a meeting
of shareholders at which a quorum is present.  

    3.07   Place of Meetings.  Meetings of the board of directors, regular or
special, may be held in or out of the State of Texas.

    3.08   First Meetings.  The first meeting of a newly elected board of
directors shall be held without further notice immediately following the annual
meeting of shareholders, and at the same 


                                          5



place, unless by unanimous consent of the directors then elected and serving,
the time or place is changed.

    3.09   Regular Meetings.  Regular meetings of the board of directors may be
held without notice at such time and place as shall from time to time be
determined by the board.

    3.10   Special Meetings.  Special meetings of the board of directors may be
called by the chairman of the board or president on five (5) days' notice to
each director, either personally, by mail, telegram or telefax.  Special
meetings shall be called by the president or secretary in like manner and on
like notice upon the written request of two directors.  Except as otherwise
expressly provided by statute, the articles of incorporation, or these bylaws,
neither the business to be transacted at, nor the purpose of, any special
meeting need be specified in a notice or waiver of notice.

    3.11   Quorum; Majority Vote.  At meetings of the board of directors a
majority of the number of directors fixed by these bylaws (less any unfilled
vacancies) shall constitute a quorum for the transaction of business.  The act
of a majority of the directors present at a meeting at which a quorum is present
shall be the act of the board of directors, except as otherwise specifically
provided by statute, the articles of incorporation, or these bylaws.  If a
quorum is not present at a meeting of the board of directors, the directors
present may adjourn the meeting from time to time, without notice other than
announcement at the meeting, until a quorum is present.

    3.12   Compensation.  By resolution of the board of directors, the
directors may be paid their expenses, if any, of attendance at each meeting of
the board of directors and may be paid a fixed sum for attendance at each
meeting of the board of directors or a stated salary as director.  No such
payment shall preclude any director from serving the corporation in any other
capacity and receiving compensation  therefor.  

    3.13   Procedure.  At meetings of the board of directors, business shall be
transacted in such order as the board of directors may determine.  The board of
directors shall keep regular minutes of its proceedings.  The minutes shall be
placed in the minute book of the corporation.

    3.14   Interested Directors and Officers.

           (a)     Validity.  If Subsection (b) of this Section is satisfied,
    no contract or other transaction between the corporation and any of its
    directors or officers or any corporation, partnership, association, or
    other organization in which any of them have a financial interest or is
    otherwise directly or indirectly interested, shall be void or voidable
    solely because of this relationship or because of the presence of the
    director or officer at the meeting authorizing the contract or transaction,
    or his participation or vote in the meeting or authorization.

           (b)     Disclosure, Approval; Fairness.  Subsection (a) shall apply
    only if:

              (i)  the material facts of the relationship or interest of each
           such director or officer are known or disclosed:

                   (A)  to the board of directors or applicable committee
              thereof and it nevertheless in good faith authorizes the contract
              or transaction by a majority of the disinterested directors
              present, even though such disinterested directors be less than a
              quorum; or

                   (B)  to the shareholders at a meeting of the shareholders
              and they nevertheless in good faith approve the contract or
              transaction by a majority of the shares present; or

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

           (c)     Non-Exclusive.  This provision shall not be construed to
    invalidate a contract or transaction which would be valid in the absence of
    this provision.

    3.15   Presumption of Assent.  A director of the corporation who is present
at any meeting of the board of directors or applicable committee thereof at
which action on any matter is taken shall be 


                                          7



presumed to have assented to the action unless his dissent shall be entered in
the minutes of the meeting or unless he shall file his written dissent to such
action with the person acting as secretary of the meeting before the adjournment
thereof or shall forward any dissent by certified or registered mail to the
secretary of the corporation immediately after the adjournment of the meeting. 
Such right to dissent shall not apply to a director who voted in favor of such
action.


                                ARTICLE 4:  COMMITTEES

    4.01   Designation.  The board of directors may, by resolution adopted by a

director, (b) his resignation as a committee member or director, or (c) his
removal as a committee member or director.

    4.03   Authority.  Each committee, to the extent provided in the resolution
establishing such committee, shall have and may exercise any or all of the
authority of the board of directors in the management of the business and
affairs of the corporation.  However, no committee shall have the authority of
the board in reference to:

           (a)     amending the articles of incorporation, except that a
    committee may, to the extent provided in the resolution designating the
    committees or in the articles of incorporation or the bylaws, exercise the
    authority vested in it in accordance with Article 2.13 of the Texas
    Business Corporations Act;

           (b)     approving a plan of merger or share exchange;

           (c)     recommending to the shareholders the sale, lease or exchange

    assets of the corporation otherwise than in the usual and regular course of
    its business;

           (d)     recommending to the shareholders a voluntary dissolution of

incorporation, these bylaws or otherwise, notice is required to be given to a
director, committee member or shareholder, a waiver thereof in writing signed by
the person or persons entitled to such notice, whether before or after the time

Attendance at a meeting shall constitute a waiver of notice of such meeting,
except where a person attends for the express purpose of objecting to the
transaction of any business on the ground that the meeting is not lawfully
called or convened.

committee members may participate in and hold a meeting by means of a conference
telephone or similar communications equipment by means of which persons
participating in the meeting can hear each other.  Participation in such a

called or convened.

    5.04   Action Without Meeting.  Any action which may be taken, or is
required by law, the articles of incorporation or these bylaws to be taken, at a
meeting of shareholders, directors or any committee members may be taken without
notice and without a meeting if a consent in writing, setting forth the action
so taken, shall be signed by (a) in the case of shareholders, either (i) all of
the shareholders entitled to vote with respect to such action, or (ii) if the
articles of incorporation so provide, by the holder or holders of shares having
not less than the minimum number of votes that would be necessary to take such
action at a meeting at which the holders of all shares entitled to vote on the
action were present and voted, and (b) in the case of directors or committee
members, all of such members of the board of directors or committee, as the case
may be, entitled to vote with respect to the subject matter thereof.  Such
consent shall have the same force and effect, as of the date stated therein, as
a unanimous vote of such shareholders, directors or committee members, as the
case may be, 


                                          11



and may be stated as such in any document filed with the Secretary of State of
Texas or in any certificate or other document delivered to any person.  The
consent may be in one or more counterparts so long as each shareholder, director

uncertificated shares a written notice containing the information required to be
stated on certificates representing shares of stock as set forth in Section 7.02

    shall constitute payment or part payment for the issuance of shares.

           (b)     Valuation.  In the absence of fraud in the transaction, the
    judgment of the board of directors as to the value of consideration
    received shall be conclusive.

agreement, subscriptions for shares, whether made before or after organization
of the corporation, shall be paid in full at such time or in such installments
and at such times as shall be determined by the board of directors.  Any call
made by the board of directors for payment on subscriptions shall be uniform as
to all shares of the same class or as to all shares of the same series, as the

payment is due, the corporation may proceed to collect the amount due in the
same manner as any debt due to the corporation.

    sureties, with fixed or open penalty, as the corporation may direct, to
    indemnify the corporation (and its transfer agent and registrar, if any)
    against any claim that may be made on account of the alleged loss,
    destruction or theft of the certificate; and

           (d)     Other Requirements.  Satisfies any other reasonable
    requirements imposed by the corporation.
