                           AMENDED AND RESTATED BYLAWS

                                    ARTICLE I
                                     OFFICES

                  1.1 The principal office of the corporation shall be located
at 530 Lovett Boulevard, Houston, Texas 77006-4021.

                  1.2 The corporation may also have offices at such other places
both within and without the State of Texas as the board of directors may from
time to time determine or the business of the corporation may require.


                                   ARTICLE II
                            MEETINGS OF SHAREHOLDERS

                  2.1 Meetings of shareholders for any purpose may be held at
such time and place within or without the State of Texas as shall be stated in
the notice of the meeting or in a duly executed waiver of notice thereof.

                  2.2 The annual meeting of shareholders shall be held annually
at such date and time as shall be designated from time to time by the board of
directors and stated in the notice of meeting.

                  2.3 Special meetings of the shareholders for any purpose or
purposes may be called by the president and shall be called by the president or
secretary at the request in writing of a majority of the board of directors, or
at the request in writing of shareholders owning ten percent (10%) of all the
shares entitled to vote at the meetings. A request for a special meeting shall
state the purpose or purposes of the proposed meeting, and business transacted
at any special meeting of shareholders shall be limited to the purposes stated
in the notice.

                  2.4 Written 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 (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 persons
calling the meeting, to each shareholder of record entitled to vote at such
meeting.

                  2.5 With respect to any matter, the holders of a majority of
each class and series of the shares issued and outstanding and entitled to vote
thereon as a class or series, present in person or represented by proxy, shall
constitute a quorum at all meetings of the shareholders for the transaction of
business except as otherwise provided by statute or by the articles of
incorporation.


   2

If, however, a quorum shall not be present or represented at any meeting of the
shareholders, the shareholders entitled to vote thereat, present in person or
represented by proxy, shall have power to 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 at that meeting, without notice other than announcement at the
meeting, until a quorum shall be present or represented. At such adjourned
meeting, provided a quorum shall be present or represented thereat, any business
may be transacted which might have been transacted if the meeting had been held
in accordance with the original notice thereof.

                  2.6 If a quorum is present at any meeting, the vote of the
holders of a majority of each class and series of the shares entitled to vote,
present in person or represented by proxy, shall decide any question brought
before such meeting, unless the question is one upon which a different vote is
required by law or by the articles of incorporation.

                  2.7 Each outstanding share having voting power shall be
entitled to one vote on each matter submitted to a vote at a meeting of
shareholders. A shareholder may vote either in person or by proxy executed in
writing by the shareholder or by his duly authorized attorney-in-fact.

                  2.8 Any action required or which may be taken at a meeting of
the shareholders may be taken without a meeting if a consent in writing, setting
forth the action so taken, shall be signed by all or less than all, if the
articles of incorporation so provide, the shareholders entitled to vote with
respect to the subject matter thereof. Whenever action by shareholders is
proposed to be taken by consent in writing without a meeting of the
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 the Texas Business
Corporation Act, 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 agent of the corporation having
custody of the books in which proceedings of the 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 the Texas Business
Corporation Act, 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 the prior
action.

                                    DIRECTORS

                  3.1 The number of directors which shall constitute the whole
board of directors shall be not less than one nor more than thirteen; provided,
that up to seven additional directors may be elected by the holders of Class B
Common Stock pursuant to the corporation's Articles of Incorporation. Such
number of directors shall from time to time be fixed and determined by the
directors and shall be set forth in the notice of any meeting of shareholders
held for the purpose of electing directors. The director(s) shall be elected at
the annual meeting of shareholders, except as provided in Section 3.2 or 3.3,
and each director elected shall hold office until his successor shall be elected
and qualify. Directors need not be residents of Texas or shareholders of the
corporation.

                  3.2 Any vacancy occurring in the board of directors may be
filled by a majority of the remaining directors, if any, though less than a
quorum of the board of directors; provided, that any vacancy occurring in a
position originally elected by the holders of Class B Common Stock may only be
filled by a vote of the holders of Class B Common Stock. If a vacancy occurs in
the board of directors and no other directors exist to elect someone to fill
such vacancy, such vacancy shall be filled by election at a special meeting of
shareholders. A director elected to fill a vacancy shall be elected for the
unexpired term of his predecessor in office.

                  3.3 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 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.

                  3.4 Subject to the provisions of the corporation's Articles of
Incorporation, any director may be removed either for or without cause at any
special meeting of shareholders duly called and held for such purpose.


                       MEETINGS OF THE BOARD OF DIRECTORS

                  3.5 Meetings of the board of directors, regular or special,
may be held either within or without the State of Texas.

                  3.6 The first meeting of each newly elected board of directors
shall be held at such time and place as shall be fixed by the vote of the
shareholders at the annual meeting and no notice of such meeting shall be
necessary to the newly elected directors in order legally to constitute the
meeting, provided a quorum shall be present. In the event that the shareholders
fail to fix the time and place of such first meeting, it shall be held without
notice immediately following the annual


                                       3

   4


meeting of shareholders, and at the same place, unless by the unanimous consent
of the directors then elected and serving such time or place shall be changed.

                  3.7 Regular meetings of the board of directors may be held
upon such notice, or without notice, and at such time and at such place as shall
from time to time be determined by the board.

                  3.8 Special meetings of the board of directors may be called
by the chairman of the board of directors or the president and shall be called
by the secretary on the written request of two directors. Notice of each special
meeting of the board of directors shall be given to each director at least two
days before the date of the meeting.

                  3.9 Attendance of a director at any meeting shall constitute a
waiver of notice of such meeting, except where a director 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. Except as may be otherwise
provided by law or by the articles of incorporation or by these bylaws, neither
the business to be transacted at, nor the purpose of, any regular or special
meeting of the board of directors need be specified in the notice or waiver of
notice of such meeting.

                  3.10 At all meetings of the board of directors a majority of
the directors shall 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 shall be the act of the board of directors, unless otherwise specifically
provided by law, the articles of incorporation or these bylaws. If a quorum
shall not be present thereat the directors may adjourn the meeting from time to
time, without notice other than announcement at the meeting, until a quorum
shall be present.

                  3.11 The board of directors, by resolution passed by a
majority of the full board, may from time to time designate a member or members
of the board of directors to constitute committees, including an executive
committee, which shall in each case consist of one or more directors and shall
have and may exercise such powers, as the board of directors may determine and
specify in the respective resolutions appointing them. A majority of all the
members of any such committee may determine its action and fix the time and
place of its meetings, unless the board of directors shall otherwise provide.
The board of directors shall have power at any time to change the number,
subject as aforesaid, and members of any such committee, to fill vacancies and
to discharge any such committee.

                  3.12 Any action required or permitted to be taken at a meeting
of the board of directors or any committee may be taken without a meeting if a
consent in writing, setting forth the action so taken, is signed by all the
members of the board of directors or committee, as the case may be.

                  3.13 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

                                       4

   5

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.

                  3.14 The board of directors may appoint such number of board
observers as it shall from time to time determine. Each board observer appointed
shall hold office for the term for which he is elected or until his earlier
death, resignation, retirement or removal by the board of directors. The board
observers may attend and be present at the meetings of the board of directors,
although a meeting of the board of directors may be held without notice to the
board observers and the board observers shall not be considered in determining
whether a quorum of the board of directors is present. The board observers shall
advise and counsel the board of directors on the business and operations of the
Corporation as requested by the board of directors; however, the board observers
shall not be entitled to vote on any matter presented to the board of directors.

                                   ARTICLE IV
                                     NOTICES

                  4.1 Any notice to directors or shareholders shall be in
writing and shall be delivered personally or mailed to the directors or
shareholders at their respective addresses appearing on the records of the
corporation. Notice by mail shall be deemed to be given at the time when the
same shall be deposited in the United States mail, postage prepaid. Notice to
directors may also be given by telegram, telecopy or fax.

                  4.2 Whenever any notice is required to be given under the
provisions of the statutes or of the articles of incorporation or of these
bylaws, 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.

                                    ARTICLE V
                                    OFFICERS

                  5.1 The officers of the corporation shall be elected by the
board of directors and shall consist of a president and a secretary. The board
of directors may also establish the positions of chairman of the board,
treasurer, vice president, an assistant president, assistant vice presidents and
one or more assistant secretaries and assistant treasurers. Two or more offices
may be held by the same person.

                  5.2 The board of directors shall elect officers of the
corporation, none of whom need be a member of the board of directors. The board
of directors shall have the power to enter into contracts for the employment and
compensation of officers for such terms as the board of directors deems
advisable.

                  5.3 The board of directors may appoint such other officers and
assistant officers and agents as it shall deem necessary, who shall hold their
offices for such terms and shall have such authority and exercise such powers
and perform such duties as shall be determined from time to time by the board of
directors by resolution not inconsistent with these bylaws.

                  5.4 The salaries of all officers and agents of the corporation
shall be fixed by the board of directors.

                  5.5 The officers of the corporation shall hold office until
their successors are elected or appointed and qualify, or until their death or
until their resignation or removal from office. Any officer elected or appointed
by the board of directors may be removed at any time by the board of directors,
but such removal shall be without prejudice to the contract rights, if any, of
the person so removed. Election or appointment of an officer or agent shall not
of itself create contract rights. Any vacancy occurring in any office of the
corporation by death, resignation, removal or otherwise shall be filled by the
board of directors.

                  5.6 The chairman of the board of directors, if one be elected,

corporation, shall have general and active management of the business of the
corporation and shall see that all orders and resolutions of the board of
directors are carried into effect. He shall preside at all meetings of the
shareholders.

                               THE VICE PRESIDENTS

                  5.8 The vice presidents in the order of their seniority,
unless otherwise determined by the board of directors, shall, in the absence or
disability of the president, perform the duties and have the authority and
exercise the powers of the president. They shall perform such other duties and
have such other authority and powers as the board of directors may from time to
time prescribe or as the president may from time to time delegate.

                  5.9 The secretary shall attend all meetings of the board of
directors and all meetings of shareholders and record all of the proceedings of

                  5.10 The assistant secretaries in the order of their
seniority, unless otherwise determined by the board of directors, shall, in the

                        CERTIFICATES REPRESENTING SHARES

                  6.1 The shares of the corporation shall be represented by
certificates signed by the president and may be sealed with the seal of the
corporation or a facsimile thereof.

                  6.2 The signature of the president upon a certificate may be a
facsimile if the certificate is countersigned by a transfer agent, or registered
by a registrar, other than the corporation itself or an employee of the
corporation. In case the president who has signed or whose facsimile signature
has been placed upon such certificate shall have ceased to be president before
such certificate is issued, it may be issued by the corporation at the date of
its issue.

                                LOST CERTIFICATES

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

                  6.4 Upon surrender to the corporation or the transfer agent of
the corporation of a certificate representing shares duly endorsed or

transfer records of the corporation.

                        CLOSING OF SHARE TRANSFER RECORDS

                  6.5 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 payment of any 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 under section 2.8, the board of directors may
provide that the share transfer records shall be closed for a stated period but
not to exceed, in any case, 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 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 for the determination of
shareholders entitled to notice of or to vote at a meeting

                                       8

   9

of shareholders, or shareholders entitled to receive payment of a dividend, the
date on which notice of the meeting is mailed or the date on which the
resolution of the board of directors declaring such 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 in this section, such determination shall
be applied to any adjournment thereof except where the determination has been
made through the closing of the share transfer records and the stated period of
closing has expired.

                             REGISTERED SHAREHOLDERS

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

                              LIST OF SHAREHOLDERS

                  6.7 The officer or agent having charge of the share transfer
records shall make, at least ten (10) days before each meeting of shareholders,
a complete list of the shareholders entitled to vote at such meeting, arranged
in alphabetical order, with the address of each and the number of shares held by
each, which list, for a period of ten (10) days prior to such 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. Such list shall also be produced and kept open at
the time and place of the meeting and shall be subject to the inspection of any
shareholder during the whole time of the meeting. The original share ledger or
transfer record, or a duplicate thereof, shall be prima facie evidence as to who
are the shareholders entitled to examine such list or share ledger or transfer
record or to vote at any meeting of shareholders.

                               GENERAL PROVISIONS

may be paid in cash, in property or in the corporation's own shares, subject to
any provisions of the articles of incorporation.

                  7.2 Before payment of any dividend, there may be set aside out
of any funds of the corporation available for dividends such sum or sums as the
directors, from time to time in their absolute discretion, think proper as a
reserve fund for meeting contingencies, or for equalizing dividends, or for
repairing or maintaining any property of the corporation, or for such other
purpose

                                       9

as the directors shall think conducive to the interest of the corporation, and
the directors may modify or abolish any such reserve in the manner in which it
was created.

prescribed by the board of directors. The seal may be used by causing it or a
facsimile thereof to be impressed or affixed or in any manner reproduced.

                                BOOKS AND RECORDS

                  7.6 The corporation shall keep correct and complete books and
records of account and shall keep minutes of the proceedings of its shareholders
and board of directors, and shall keep at its registered office or principal
place of business, or at the office of its transfer agent or registrar, a record

foreign or domestic corporation, partnership, joint venture, sole
proprietorship, trust, employee benefit plan or other enterprise against any
liability asserted against him and incurred by him in such a capacity or arising

advance expenses to directors under this Article IX.

                  9.4 Notwithstanding any other provision of this Article IX,
the corporation may pay or reimburse expenses incurred by a director or officer

corporation or these bylaws, agreement, vote of shareholders or disinterested
directors or otherwise.

                  9.6 The corporation may purchase and maintain insurance, at

indemnification or advance.

                  9.8 If this Article IX 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 IX 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
