make a determination of shareholders for any other purpose, the Board of
Directors of the Corporation may provide that the stock transfer books shall be
closed for a stated period but not to exceed, in any case, 60 days nor be less

distribution or share 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 provided herein, such determination shall also
apply to any adjournment thereof except where the determination has been made
through the closing of stock transfer books and the stated period of closing has
expired.
 
        Section 6. Notice of Meetings. Written or printed notice stating the
place, day and hour of the meeting and, in the case of a special meeting, the
purpose or purposes for which the meeting is called, shall be delivered not less
than ten nor more than 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 of record entitled to
vote at such meeting. If mailed, any 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 books of the Corporation, with
postage thereon prepaid.
 
        Any notice required to be given to any shareholder, under any provision
of the Texas Business Corporation Act or the Articles of Incorporation or these
bylaws need not be given to the shareholder if (a) notice of two consecutive
annual meetings and all notices of meetings held during the period between those
annual meetings, if any, or (b) all (but in no event less than two) payments of
distributions or interest on securities during a 12-month period have been
mailed to that person by first-class mail, addressed to him at his address as
shown on the records of the Corporation, and have been returned undeliverable.
Any action or meeting taken or held without notice to such person shall have the
same force and effect as if the notice had been duly given and, if the action
taken by the Corporation is reflected in any articles or document filed with the
Secretary of State, those articles or that document may state that notice was
duly given to all persons to whom notice was required to be given. If such a
person delivers to the Corporation written notice setting forth his then current
address, the requirement that notice be given to that person shall be
reinstated.
 
        Section 7. Voting List. The officer or agent having charge of the stock
transfer books for shares of the Corporation shall make, at least ten days
before each meeting of shareholders, a complete list of the shareholders
entitled to vote at such meeting or any adjournment thereof, arranged in
alphabetical order, with the address of 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 stock transfer books shall be prima-facie evidence as
to who are the shareholders entitled to
 
                                        3
 
<PAGE>
 
examine such list or transfer books or to vote at any meeting of shareholders.
Failure to comply with the requirements of this Section shall not affect the
validity of any action taken at such meeting.
 
        Section 8. Proxies. A shareholder may vote either in person or by proxy
executed in writing by the shareholder or by his duly authorized attorney-in-
fact. Proxies for use at any meeting of shareholders or in connection with the
taking of any action by written consent shall be filed with the Secretary, or
such other officer as the Board of Directors may from time to time determine by
resolution, before or at the time of the meeting or execution of the written
consent, as the case may be. All proxies shall be received and taken charge of
and all ballots shall be received and canvassed by the secretary of the meeting
who shall decide all questions touching upon the qualification of voters, the
validity of the proxies, and the acceptance or rejection of votes, unless an
inspector or inspectors shall have been appointed by the chairman of the
meeting, in which event such inspector or inspectors shall decide all such
questions.
 
        No proxy shall be valid after 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. Proxies coupled with an interest shall include the
appointment as proxy of any of the persons set forth in the Texas Business
Corporation Act, including without limitation:
 
                (a)     a pledgee;
 
                (b)     a person who purchased or agreed to purchase, or owns or
                        holds an option to purchase, the shares;
 
                (c)     a creditor of the Corporation who extended it credit
                        under terms requiring the appointment;
 
                (d)     an employee of the Corporation whose employment contract
                        requires the appointment; or
 
                (e)     a party to a voting agreement executed under Section B,
                        Article 2.30 of the Texas Business Corporation Act.
 
Should a proxy designate two or more persons to act as proxies, unless such
instrument shall provide to the contrary, a majority of such persons present at
any meeting at which their powers thereunder are to be exercised shall have and
may exercise all the powers of voting or giving consents thereby conferred, or
if only one be present, then such powers may be exercised by that one; or, if an
even number attend and a majority do not agree on any particular issue, the
Corporation shall not be required to recognize such proxy with respect to such
issue if such proxy does not specify how the shares that are the subject of such
proxy are to be voted with respect to such issue.

        Section 9. Voting; Elections; Inspectors. Unless otherwise required by
law or 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.
 
        All voting, except as required by the Articles of Incorporation or where
otherwise required by law, may be by a voice vote; provided, however, that a
vote by ballot shall be taken upon demand therefor by shareholders holding
issued and outstanding shares representing a majority of the voting power
present in person or by proxy at any meeting. Every vote by ballot shall be
taken by written ballots, each of which shall state the name of the shareholder
or proxy voting and such other information as may be required under the
procedure established for the meeting.
 
        At any meeting at which a vote is taken by ballots, the chairman of the
meeting may appoint one or more inspectors, each of whom shall subscribe an oath
or affirmation to execute faithfully the duties of inspector at such meeting
with strict impartiality and according to the best of his ability. Such
inspector shall receive the ballots, count the votes and make and sign a
certificate of the result thereof. The chairman of the meeting may appoint any
person to serve as inspector, except no candidate for the office of director
shall be appointed as an inspector.
 
        At each election of directors each shareholder entitled to vote thereat
shall, unless otherwise provided by law or by the Articles of Incorporation,
have the right to vote the number of shares owned by him for as many persons as
there are to be elected and for whose election he has a right to vote. Unless
expressly prohibited by the Articles of Incorporation, a shareholder shall have
the right to cumulate his votes by giving one candidate as many votes as the
number of such directors multiplied by his shares shall equal, or by
distributing such votes on the same principle among any number of such
candidates. Any shareholder who intends to cumulate his votes shall give written
notice of such intention to the Secretary of the Corporation on or before the
day preceding the election at which such shareholder intends to cumulate his
votes. Any shareholder may cumulate his votes if such shareholder or any other
shareholder gives the written notice provided for herein.
 
        Section 10. Conduct of Meetings. All meetings of the shareholders shall
be presided over by the chairman of the meeting, who shall be the Chairman of
the Board (if any), or if he is not present, the President, or if neither the
Chairman of the Board (if any) nor President is present, a chairman elected at
the meeting. The Secretary of the Corporation, if present, shall act as
secretary of such meetings, or if he is not present, an Assistant Secretary (if
any) shall so act; if neither the Secretary nor an Assistant Secretary (if any)
is present, then a secretary shall be appointed by the chairman of the meeting.
The chairman of any meeting of shareholders shall determine the order of
business and the procedure at the meeting, including such regulation of the
manner of voting and the conduct of discussion as seem to him in order.

        Section 11. Treasury Shares. Neither the Corporation nor any other
person shall vote, directly or indirectly, at any meeting, shares of the
Corporation's own stock owned by the Corporation, shares of the Corporation's
own stock owned by another corporation the majority of the voting stock of which
is owned or controlled by the Corporation, and shares of the Corporation's own
stock held by the Corporation in a fiduciary capacity; and such shares shall not
be counted in determining the total number of outstanding shares at any given
time.
 
        Section 12. Notice of Shareholder Business and Nominations.
 
                (a)     Annual Meetings of Shareholders.
 
                        (1)     Nominations of persons for election to the Board
of Directors of the Corporation and the proposal of business to be considered by
the shareholders may be made at an annual meeting of shareholders (a) pursuant
to the Corporation's notice of meeting, (b) by or at the direction of the Board
of Directors or (c) by any shareholder of the Corporation who was a shareholder
of record at the time of giving of notice provided for in this Bylaw, who is
entitled to vote at such meeting and who complies with the notice procedures set
forth in this Bylaw.
 
                        (2)     For nominations or other business to be properly
brought before an annual meeting by a shareholder pursuant to clause (c) of
paragraph (a)(1) of Section 12 of this Bylaw, the shareholder must have given
timely notice thereof in writing to the Secretary of the Corporation and such
other business must otherwise be a proper matter for shareholder action. To be
timely, a shareholder's notice shall be delivered to the Secretary at the
principal executive offices of the Corporation not later than the close of
business on the 90th day, nor earlier than the close of business on the 120th
day, prior to the first anniversary of the preceding year's annual meeting;
provided, however, that in the event that the date of the annual meeting is more
than 30 days before or more than 60 days after such anniversary date, notice by
the shareholder to be timely must be so delivered not earlier than the close of
business on the 120th day prior to such annual meeting and not later than the
close of business on the later of the 90th day prior to such annual meeting or
the 10th day following the day on which public announcement of the date of such
meeting is first made by the Corporation. In no event shall the public
announcement of an adjournment of an annual meeting commence a new time period
for the giving of a shareholder's notice as described above. Such shareholder's
notice shall set forth (a) as to each person whom the shareholder proposes to
nominate for election or reelection as a director all information relating to
such person that is required to be disclosed in solicitations of proxies for
election of directors in an election contest, or is otherwise required, in each
case pursuant to Regulation 14A under the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), and Rule 14a-11 thereunder (including such
person's written consent to being named in the proxy statement as a nominee and
to serving as a director if elected); (b) as to any other business that the
shareholder proposes to bring before the meeting, a brief description of the
business desired to be brought before the meeting, the reasons for conducting
such business at the meeting and any material interest in such business of such
shareholder and the beneficial
 
                                        6
 
<PAGE>
 
owner, if any, on whose behalf the proposal is made; and (c) as to the
shareholder giving the notice and the beneficial owner, if any, on whose behalf
the nomination or proposal is made (i) the name and address of such shareholder,
as they appear on the Corporation's books, and of such beneficial owner and (ii)
the class or series and number of shares of the Corporation which are owned
beneficially and of record by such shareholder and such beneficial owner.
 
                        (3)     Notwithstanding anything in the second sentence
of paragraph (a)(2) of Section 12 of this Bylaw to the contrary, in the event
that the number of directors to be elected to the Board of Directors of the
Corporation is increased and there is no public announcement by the Corporation
naming all of the nominees for director or specifying the size of the increased
Board of Directors at least 100 days prior to the first anniversary of the
preceding year's annual meeting, a shareholder's notice required by this Bylaw
shall also be considered timely, but only with respect to nominees for any new
positions created by such increase, if it shall be delivered to the Secretary at
the principal executive offices of the Corporation not later than the close of
business on the 10th day following the day on which such public announcement of
the increased Board is first made by the Corporation.
 
                (b)     Special Meetings of Shareholders. Only such business
shall be conducted at a special meeting of shareholders as shall have been
brought before the meeting pursuant to the Corporation's notice of meeting.
Nominations of persons for election to the Board of Directors may be made at a
special meeting of shareholders at which directors are to be elected pursuant to
the Corporation's notice of meeting (1) by or at the direction of the Board of
Directors or (2) provided that the Board of Directors has determined that
directors shall be elected at such meeting, by any shareholder of the
Corporation who is a shareholder of record at the time of giving of notice
provided for in this Bylaw, who shall be entitled to vote at the meeting and who
complies with the notice procedures set forth in this Bylaw. In the event the
Corporation calls a special meeting of shareholders for the purpose of electing
one or more directors to the Board of Directors, any such shareholder may
nominate a person or persons (as the case may be), for election to such
position(s) as specified in the Corporation's notice of meeting, if the
shareholder's notice required by paragraph (a)(2) of this Bylaw shall be
delivered to the Secretary at the principal executive offices of the Corporation
not earlier than the close of business on the 120th day prior to such special
meeting and not later than the close of business on the later of the 90th day
prior to such special meeting or the 10th day following the day on which public
announcement is first made of the date of the special meeting and of the
nominees proposed by the Board of Directors to be elected at such meeting. In no
event shall the public announcement of an adjournment of a special meeting
commence a new time period for the giving of a shareholder's notice as described
above.
 
                (c)     General.
 
                        (1)     Only such persons who are nominated in
accordance with the procedures set forth in this Bylaw shall be eligible to
serve as directors, and only such business shall be conducted at a meeting of
shareholders as shall have been brought
 
                                        7
 
<PAGE>
 
before the meeting in accordance with the procedures set forth in this Bylaw.
Except as otherwise provided by law, the Articles of Incorporation or these
Bylaws, the chairman of the meeting shall have the power and duty to determine
whether a nomination or any business proposed to be brought before the meeting
was made or proposed, as the case may be, in accordance with the procedures set
forth in this Bylaw and, if any proposed nomination or business is not in
compliance with this Bylaw, to declare that such defective proposal or
nomination shall be disregarded.
 
                        (2)     For purposes of this Bylaw, "public
announcement" shall mean disclosure in a press release reported by the Dow Jones
News Service, Associated Press or comparable national news service or in a
document publicly filed by the Corporation with the Securities and Exchange
Commission pursuant to Section 13, 14 or 15(d) of the Exchange Act.
 
                        (3)     Notwithstanding the foregoing provisions of this
Bylaw, a shareholder shall also comply with all applicable requirements of the
Exchange Act and the rules and regulations thereunder with respect to the
matters set forth in this Bylaw. Nothing in this Bylaw shall be deemed to affect
any rights (a) of shareholders to request inclusion of proposals in the
Corporation's proxy statement pursuant to Rule 14a-8 under the Exchange Act or
(b) of the holders of any series of Preferred Stock to elect directors under
specified circumstances.

Incorporation, the number of directors that shall constitute the whole board of
directors shall from time to time be fixed exclusively by the board of directors

the time of that vote. Except in the event of a vacancy contemplated by Section
1(c) of this Article III, in no event shall the number of directors that
constitute the whole board of directors be fewer than three. No decrease in the
number of directors shall have the effect of shortening the term of any
incumbent director. Directors of the Corporation need not be elected by written
ballot unless the by-laws of the Corporation otherwise provide. Unless otherwise

the Corporation or residents of the State of Texas.

person or represented by proxy and entitled to vote on the election of

cause and newly- created directorships resulting from any increase in the
authorized number of directors may be filled by no less than a majority vote of
the remaining directors then in office, though less than a quorum, and shall
hold office until the first meeting of shareholders held after his election for
the purpose of electing directors and until his successor is elected and
qualified or until his earlier death, resignation, or removal from office. Any
such vacancies which result in the number of directors being less than three
shall be promptly filled according to the procedures set forth in this
paragraph.
 
                (d)     A director of the Corporation may be removed before the
expiration date of that director's term of office only for cause, by an

required by law or provided in the Articles of Incorporation or these bylaws, a
majority of the total number of directors shall constitute a quorum for the

be determined by the Chairman of the Board (if any), or in his absence by the
President (if the President is director), or by resolution of the Board of
Directors.

such time and place shall not be required.

may be called by the Chairman of the Board (if any), the President or, on the
written request of any one director, by the Secretary, in each case on at least

director. Such notice, or any waiver thereof pursuant to Article VIII, Section 3
hereof, need not state the purpose or purposes of such meeting, except as may
otherwise be required by law or provided for by the Articles of Incorporation or
these bylaws.
 
        Section 7. Compensation. Unless restricted by the Articles of
Incorporation, the Board of Directors shall have the authority to fix the

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 such dissent by registered mail to the
Secretary immediately after the adjournment of the meeting. Such right to
dissent shall not apply to a director who voted in favor of such action.
 
        Section 9. Approval or Ratification of Acts or Contracts by
Shareholders. The Board of Directors in its discretion may submit any act or
contract for approval or ratification at any annual meeting of the shareholders,
or at any special meeting of the shareholders called for the purpose of
considering any such act or contract, and any act or contract that shall be
approved or be ratified by the vote of the shareholders holding a majority of
the issued and outstanding shares of stock of the Corporation entitled to vote
and present in person or by proxy at such meeting (provided that a quorum is
present), shall be as valid and as binding upon the Corporation and upon all the
shareholders as if it shall have been approved or ratified by every shareholder
of the Corporation.

extent permitted by law from and against any and all losses, claims, demands,
costs, damages, liabilities, joint or several, expenses of any nature (including
reasonable attorneys' fees and disbursements), judgments, fines, settlements and
other amounts arising from any and all claims, demands, actions, suits or
proceedings, whether civil, criminal, administrative or investigative, in which
the Indemnified Person may be involved or threatened to be involved, as a party
or otherwise, arising out of or incidental to the business or activities of or
relating to the Corporation regardless of whether the Indemnified Person
continues to be a Director at the time any such liability or expense is paid or
incurred. The indemnification provided in this Article VIII may not be made to
or on behalf of any Director if a final adjudication establishes that the
indemnified persons acts or omissions involved intentional misconduct, fraud or
a knowing violation of the law. and indemnification under this Article VI shall
continue as to a person who has ceased to serve in the capacity which initially
entitled such person to indemnity hereunder. The rights granted pursuant to this
Article VI shall be deemed contract rights, and no amendment, modification or
repeal of this Article VI shall have the effect of limiting or denying any such
rights with respect to actions taken or proceedings arising prior to any such
amendment, modification or repeal. It is expressly acknowledged that the
indemnification provided in this Article VI could involve indemnification for
negligence or under theories of strict liability.
 
        Section 2. Advance Payment. The right to indemnification conferred in
this Article VI shall include the right to be paid or reimbursed by the
Corporation the reasonable expenses incurred by a person of the type entitled to
be indemnified under Section 1 who was, is or is threatened to be made a named
defendant or respondent in a proceeding in advance of the final disposition of
the proceeding and without any determination as to the person's ultimate
entitlement to indemnification; provided, however, that the payment of such
expenses incurred by any such person in advance of the final disposition of a
proceeding, shall be made only upon delivery to the Corporation of a written
affirmation by such director or officer of his or her good faith belief that he
or she has met the standard of conduct necessary for indemnification under this
Article VI and a written undertaking, by or on behalf of such person, to repay
all amounts so advanced if it shall ultimately be determined that such
indemnified person is not entitled to be indemnified under this Article VI or
otherwise.

<PAGE>
 
        Section 3. Appearance as a Witness. Notwithstanding any other provision
of this Article VI, the Corporation may pay or reimburse expenses incurred by a
director or officer in connection with his or her appearance as a witness or
other participation in a proceeding at a time when he or she is not a named
defendant or respondent in the proceeding.
 
        Section 4. Nonexclusivity of Rights. The right to indemnification and
the advancement and payment of expenses conferred in this Article VI shall not
be exclusive of any other right which a director or officer or other person

Incorporation of the Corporation or these bylaws, agreement, vote of
shareholders or disinterested directors or otherwise.

venturer, proprietor, trustee, employee, agent or similar functionary of another
foreign or domestic corporation, partnership, joint venture, proprietorship,

or loss, whether or not the Corporation would have the power to indemnify such
person against such expense, liability or loss under this Article VI.
 
        Section 6. Shareholder Notification. To the extent required by law, any
indemnification of or advance of expenses to a director or officer in accordance
with this Article VI 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 shareholders of a consent to action without a
meeting and, in any case, within the 12-month period immediately following the
date of the indemnification or advance.
 
        Section 7. Savings Clause. If this Article VI or any portion hereof
shall be invalidated on any ground by any court of competent jurisdiction, then
the Corporation shall nevertheless indemnify and hold harmless each director,
officer or any other person indemnified pursuant to this Article VI as to costs,
charges and expenses (including attorneys' fees), judgments, fines and amounts
paid in settlement with respect to any action, suit or proceeding, whether
civil, criminal, administrative or investigative to the full extent permitted by
any applicable portion of this Article VI. that shall not have been invalidated

<PAGE>
 
each shareholder one or more certificates, which shall be signed by the Chairman
of the Board (if any), President or a Vice President (if any) and the Secretary
or an Assistant Secretary (if any) or the Treasurer or an Assistant Treasurer
(if any) certifying the number of shares (and, if the stock of the Corporation
shall be divided into classes or series, the class and series of such shares)
owned by such shareholder in the Corporation; provided, however, that any of or
all the signatures on the certificate may be facsimile. If the Board of
Directors shall have provided for a seal, such certificates shall bear such seal
or a facsimile thereof. The stock record books and the blank stock certificate
books shall be kept by the Secretary, or at the office of such transfer agent or
transfer agents as the Board of Directors may from time to time by resolution
determine. In case any officer, transfer agent or registrar who shall have
signed or whose facsimile signature or signatures shall have been placed upon
any such certificate or certificates shall have ceased to be such officer,
transfer agent or registrar before such certificate is issued by the
Corporation, such certificate may nevertheless be issued by the Corporation with
the same affect as if such person were such officer, transfer agent or registrar
at the date of issue. The stock certificates shall be consecutively numbered and
shall be entered in the books of the Corporation as they are issued and shall
exhibit the holder's name and number of shares.

to Article 2.19 or Article 2.22 of the Texas Business Corporation Act, as well
as any other legend required by law.

shall be transferable only on the books of the Corporation by the holders
thereof in person or by their duly authorized attorneys or legal
representatives, upon surrender and cancellation of certificates for a like
number of shares (or upon compliance with the provisions of Section 5 of this
Article VII, if applicable). Upon such surrender to the Corporation or a
transfer agent of the Corporation of a certificate for shares duly endorsed or
accompanied by proper evidence of succession, assignment or authority to
transfer (or upon compliance with the provisions of Section 5 of this Article
VII, if applicable) and of compliance with any transfer restrictions applicable
thereto contained in an agreement to which the Corporation is a party or of
which the Corporation has knowledge by reason of legend with respect thereto
placed an any such surrendered stock certificate, it shall be the duty of the
corporation to issue a new certificate to the person entitled thereto, cancel
the old certificate and record the transaction upon its books.
 
        Section 3. Ownership of Shares. The Corporation shall be entitled to
treat the holder of record of any share or shares of capital stock of the
Corporation as the holder in fact thereof and, accordingly, 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 law.
 
        Section 4. Regulations Regarding Certificates. The Board of Directors
shall have the power and authority to make all such rules and regulations as
they may deem
 
                                       16

certificates for shares of capital stock of the Corporation.
 
        Section 5. Lost, Stolen, Destroyed or Mutilated Certificates. The Board
of Directors may determine the conditions upon which a new certificate of stock
may be issued in place of a certificate that is alleged to have been lost,
stolen, destroyed or mutilated; and may, in its discretion, require the owner of
such certificate or his legal representative to give bond, with sufficient
surety, to indemnify the Corporation and each transfer agent and registrar
against any and all losses or claims which may arise by reason of the issuance
of a new certificate in the place of the one so lost, stolen, destroyed or
mutilated.

        Whenever notice is required to be given by law, the Articles of
Incorporation or these bylaws, a written waiver thereof, signed by the person
entitled to notice, whether before or after the time stated therein, shall be
deemed equivalent to notice.

may resign at any time. Such resignation shall be made in writing and shall take

records and minutes may be in written form or in any other form capable of being
converted into written form within a reasonable time.
 
        Section 7. Reliance Upon Books, Reports and Records. Neither a director
nor a member of any committee of directors shall be liable if, in the exercise

Corporation having charge of its books of account, or reported by an independent
public or certified public accountant or firm of such accountants to present
fairly the financial position of the Corporation, or (b) upon the written
opinion of an attorney for the Corporation; nor shall he be so liable if, in the
exercise of ordinary care and in good faith, in voting for or assenting to a
distribution by the Corporation, he considered the assets of the Corporation to
be of their book value.

Any action permitted or required by law, the Articles of Incorporation or these
bylaws, to be taken at a meeting of the shareholders, the Board of Directors or
any committee designated by the Board of Directors may be taken without a
meeting if a consent in writing, setting forth the action to be taken is signed
by all the shareholders or members of the Board of Directors or committee, as

objecting to the transaction of any business on the ground that the meeting is
not lawfully called or convened.
