Notwithstanding the other provisions of the Certificate of Incorporation or
these bylaws, the holders of a majority of the shares of the corporation's
capital stock entitled to vote thereat, present in person or represented by
proxy, whether or not a quorum is present, shall have power to adjourn the
meeting from time to time, without notice other than announcement at the
meeting, until a quorum shall be present or represented. If the adjournment is
for more than 30 days, or if after the adjournment a new record date is fixed
for the adjourned meeting, a notice of the adjourned meeting shall be given to
each stockholder of record entitled to vote at the meeting. At such adjourned

                 SECTION 2.07. Voting. When a quorum is present at any meeting

unless the question is one upon which, by express provision of the statutes, of
the Certificate of Incorporation or of these bylaws, a different vote is
required, in which case such express provision shall govern and control the
decision of such question. Every stockholder having the right to vote shall be
entitled to vote in person, or by proxy appointed by an instrument in writing
subscribed by such stockholder, bearing a date not more than three years prior
to voting, unless such instrument provides for a longer period, and filed with
the Secretary of the corporation before, or at the time of, the meeting. If
such instrument shall designate two or more persons to act as proxies, unless
such instrument shall provide 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,

                                      -2-

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 same portion of the shares as he is of the proxies representing such
shares.

                 SECTION 2.08.    Consent of Stockholders. Whenever the vote of
stockholders at a meeting thereof is required or permitted to be taken for or
in connection with any corporate action by any provision of the statutes, the
meeting and vote of stockholders may be dispensed with if all the stockholders
who would have been entitled to vote upon the action if such meeting were held
shall consent in writing to such corporate action being taken; or on the
written consent of the holders of shares of the corporation's capital stock
having not less than the minimum percentage of the vote required by statute for
the proposed corporate action, and provided that prompt notice must be given to
all stockholders of the taking of corporate action without a meeting and by
less than unanimous written consent.

                 SECTION 2.09.    Voting of Stock of Certain Holders. Shares of
the corporation's capital stock standing in the name of another corporation,
domestic or foreign, may be voted by such officer, agent, or proxy as the
bylaws of such corporation may prescribe, or in the absence of such provision,
as the Board of Directors of such corporation may determine. Shares standing in
the name of a deceased person may be voted by the executor or administrator of
such deceased person, either in person or by proxy. Shares standing in the name
of a guardian, conservator, or trustee may be voted by such fiduciary, either
in person or by proxy, but no such fiduciary shall be entitled to vote shares
held in such fiduciary capacity without a transfer of such shares into the name
of such fiduciary. Shares standing in the name of a receiver may be voted by
such receiver. A stockholder whose shares are pledged shall be entitled to vote
such shares, unless in the transfer by the pledgor on the books of the
corporation, he has expressly empowered the pledgee to vote thereon, in which
case only the pledgee, or his proxy, may represent the stock and vote thereon.

                 SECTION 2.10.    Treasury Stock. The corporation shall not
vote, directly or indirectly, shares of its own capital stock owned by it; and
such shares shall not be counted in determining the total number of outstanding
shares of the corporation's capital stock.

                 SECTION 2.11.    Fixing Record Date. The Board of Directors
may fix in advance a date, which shall not be more than 60 days nor less than
10 days preceding the date of any meeting of stockholders, nor more than 60
days preceding the date for payment of any dividend or distribution, or the
date for the allotment of rights, or the date when any change, or conversion or
exchange of capital stock shall go into effect, or a date in connection with
obtaining a consent, as a record date for the determination of the stockholders
entitled to notice of, and to vote at, any such meeting and any adjournment
thereof, or entitled to receive payment of any such dividend or distribution,
or to receive any such allotment of rights, or to exercise the rights in
respect of any such change, conversion or exchange of capital stock, or to give
such consent, and in such case such stockholders and only such stockholders as

                                      -3-
   4
shall be stockholders of record on the date so fixed, shall be entitled to such
notice of, and to vote at, any such meeting and any adjournment thereof, or to
receive payment of such dividend or distribution, or to receive such allotment
of rights, or to exercise such rights, or to give such consent, as the case may
be, notwithstanding any transfer of any stock on the books of the corporation
after any such record date fixed as aforesaid.

corporation shall be managed by its Board of Directors, which may exercise all
such powers of the corporation and do all such lawful acts and things as are
not by statute or by the Certificate of Incorporation or by these bylaws

                 SECTION 3.02. Number, Election and Term. The number of
directors that shall constitute the whole Board of Directors shall be not less
than one. 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 stockholders held for the purpose of electing directors. The directors shall
be elected at the annual meeting of stockholders, except as provided in Section
3.03, and each director elected shall hold office until his successor shall be
elected and shall qualify. Directors need not be residents of Delaware or
stockholders of the corporation.

                 SECTION 3.03. Vacancies, Additional Directors, and Removal
From Office. If any vacancy occurs in the Board of Directors caused by death,
resignation, retirement, disqualification, or removal from office of any
director, or otherwise, or if any new directorship is created by an increase in
the authorized number of directors, a majority of the directors then in office,
though less than a quorum, or a sole remaining director, may choose a successor
or fill the newly created directorship; and a director so chosen shall hold
office until the next election and until his successor shall be duly elected
and shall qualify, unless sooner displaced. Any director may be removed either
for or without cause at any special meeting of stockholders duly called and
held for such purpose.

                 SECTION 3.04. Regular Meeting. A regular meeting of the Board
of Directors shall be held each year, without other notice than this bylaw, at

                                      -4-
   5
any such meeting shall fix the time and any place, either within or without the
State of Delaware, as the place for holding such meeting.

                 SECTION 3.06. Notice of Special Meeting. Written notice of
special meetings of the Board of Directors shall be given to each director at
least 48 hours prior to the time of such meeting. Any director may waive notice
of any meeting. The attendance of a director at any meeting shall constitute a
waiver of notice of such meeting, except where a director attends a meeting for
the purpose of objecting to the transaction of any business because the meeting
is not lawfully called or convened. Neither the business to be transacted at,
nor the purpose of, any special meeting of the Board of Directors need be
specified in the notice or waiver of notice of such meeting, except that notice
shall be given of any proposed amendment to the bylaws if it is to be adopted
at any special meeting or with respect to any other matter where notice is
required by statute.

                 SECTION 3.07. Quorum. A majority of the Board of Directors
shall constitute a quorum for the transaction of business at any meeting of the
Board of Directors, 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,
except as may be otherwise specifically provided by statute, by the Certificate
of Incorporation or by these bylaws. If a quorum shall not be present at any
meeting of the Board of Directors, the directors present thereat may adjourn
the meeting from time to time, without notice other than announcement at the
meeting, until a quorum shall be present.

                 SECTION 3.08. Action Without Meeting. Unless otherwise
restricted by the Certificate of Incorporation or these bylaws, any action
required or permitted to be taken at any meeting of the Board of Directors, or
of any committee thereof as provided in Article IV of these bylaws, may be
taken without a meeting, if a written consent thereto is signed by all members
of the Board of Directors or of such committee, as the case may be, and such
written consent is filed with the minutes of proceedings of the Board of
Directors or such committee.

                 SECTION 3.09. Compensation. Directors, as such, shall not be
entitled to any stated salary for their services unless voted by the
stockholders or the Board of Directors; but by resolution of the Board of
Directors, a fixed sum and expenses of attendance, if any, may be allowed for
attendance at each regular or special meeting of the Board of Directors or any
meeting of a committee of directors. No provision of these bylaws shall be
construed to preclude any director from serving the corporation in any other
capacity and receiving compensation therefor.

                                   ARTICLE IV

                             COMMITTEE OF DIRECTORS

the seal of the corporation to be affixed to all papers that may require it.
The Board of Directors may designate one or more directors as alternate members
of any committee, who may replace any absent or disqualified member at any
meeting of such committee. In the absence or disqualification of any member of
such committee or committees, the member or members thereof present at any
meeting and not disqualified from voting, whether or not he or they constitute
a quorum, may unanimously appoint another member of the Board of Directors to
act at the meeting in the place of any such absent or disqualified member. Such
committee or committees shall have such name or names and such limitations of
authority as may be determined from time to time by resolution adopted by the
Board of Directors.

                 SECTION 4.02. Minutes. Each committee of directors shall keep
regular minutes of its proceedings and report the same to the Board of

personally or mailed to such director, member, or stockholder; provided that in

stockholder's address as it appears on the records of the corporation or, in
the case of a director or a member of a committee, to such person at his
business address. If sent by telegraph, notice to a director or member of a
committee shall be deemed to be given when the telegram, so addressed, is
delivered to the telegraph company.

                 SECTION 5.02. Written Waiver. Whenever any notice is required
to be given under the provisions of an applicable statute, the Certificate of
Incorporation, or these bylaws, a waiver thereof in writing, signed by the

or any employee of the corporation, or (2) by a registrar other than the
corporation or any employee of the corporation, any other signature on the
certificate may be a facsimile. If the corporation shall be authorized to issue
more than one class of stock or more than one series of any class, the
designations, preferences, and relative participating, optional, or other
special rights of each class of stock or series thereof and the qualifications,
limitations, or restrictions of such preferences and rights shall be set forth
in full or summarized on the face or back of the certificate which the
corporation shall issue to represent such class of stock; provided that, except
as otherwise provided by statute, in lieu of the foregoing requirements there
may be set forth on the face or back of the certificate which the corporation
shall issue to represent such class or series of stock, a statement that the
corporation will furnish to each stockholder who so requests the designations,
preferences and relative, participating, optional or other special rights of
each class of stock or series thereof and the qualifications, limitations, or
restrictions of such preferences and rights. All certificates surrendered to
the corporation for transfer shall be canceled and no new certificate shall be
issued until the former certificate for a like number of shares shall have been
surrendered and canceled, except that in the case of a lost, stolen, destroyed,
or mutilated certificate a new one may be issued therefor upon such terms and
with such indemnity, if any, to the corporation as the Board of Directors may
prescribe. Certificates shall not be issued representing fractional shares of
stock.

                 SECTION 8.02.    Lost Certificates. The Board of Directors may
direct a new certificate or certificates to be issued in place of any
certificate or certificates theretofore issued by the corporation alleged to
have been lost, stolen, or destroyed, upon the making of an affidavit of that
fact by the person claiming the certificate of stock to be lost, stolen or
destroyed. When authorizing such issue of a new certificate or certificates,
the Board of Directors may, in its discretion and as a condition precedent to
the issuance thereof, require (1) the owner of such lost, stolen, or destroyed
certificate or certificates, or his legal representative, to advertise the same
in such manner as it shall require, (2) such owner to give the corporation a
bond in such sum as it may direct as indemnity against any claim that may be
made against the corporation with respect to the certificate or certificates
alleged to have been lost, stolen, or destroyed, or (3) both.

                 SECTION 8.03.    Transfers. Upon surrender to the corporation
or the transfer agent of the corporation of a certificate for shares duly
endorsed or

                                      -10-
   11
accompanied by proper evidence of succession, assignment, or authority to
transfer, 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. Transfers of shares shall be made only on the books
of the corporation by the registered holder thereof, or by his attorney
thereunto authorized by power of attorney and filed with the Secretary of the
corporation or the Transfer Agent.

                 SECTION 8.04.    Registered Stockholders. The corporation
shall be entitled to treat the holder of record of any share or shares of the
corporation's capital stock 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 the laws
of the State of Delaware.

                                   ARTICLE IX

                                   DIVIDENDS

                 SECTION 9.01.    Declaration. Dividends with respect to the
shares of the corporation's capital stock, subject to the provisions of the
Certificate of Incorporation, if any, may be declared by the Board of Directors
at any regular or special meeting, pursuant to applicable law. Dividends may be
paid in cash, in property, or in shares of capital stock, subject to the
provisions of the Certificate of Incorporation.

                 SECTION 9.02.    Reserve. 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 Board of Directors from time to time, in
their absolute discretion, think proper as a reserve or reserves to meet
contingencies, or for equalizing dividends, or for repairing or maintaining any
property of the corporation, or for such other purpose as the Board of
Directors shall think conducive to the interest of the corporation, and the
Board of Directors may modify or abolish any such reserve in the manner in
which it was created.

                                   ARTICLE X

                                INDEMNIFICATION

                 SECTION 10.01. Third Party Actions. The corporation shall
indemnify any director or officer of the corporation, and may indemnify any
other person, who was or is a party or is threatened to be made a party to any
threatened, pending, or completed action, suit, or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of the corporation) by reason of the fact that he is or was a director,
officer, employee, or agent of the corporation, or is or was 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 expenses (including attorneys' fees), judgments, fines, and amounts
paid in settlement actually and reasonably incurred by him in connection with
such action,

                                      -11-
   12
suit, or proceeding if he acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the corporation, and,
with respect to any criminal action or proceeding, had no reasonable cause to
believe his conduct was unlawful. The termination of any action, suit, or
proceeding by judgment, order, settlement, or conviction, or upon a plea of
nolo contenders or its equivalent, shall not, of itself, create a presumption
that the person did not act in good faith and in a manner which he reasonably
believed to be in or not opposed to the best interests of the corporation, and,
with respect to any criminal action or proceeding, had reasonable cause to
believe that his conduct was unlawful.

                 SECTION 10.02. Actions by or in the Right of the Corporation.
The corporation shall indemnify any director or officer and may indemnify any
other person who was or is a party or is threatened to be made a party to any
threatened, pending, or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that he is
or was a director, officer, employee, or agent of the corporation, or is or was
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 expenses (including attorneys' fees) actually and reasonably
incurred by him in connection with the defense or settlement of such action or
suit if he acted in good faith and in a manner he reasonably believed to be in
or not opposed to the best interests of the corporation and except that no
indemnification shall be made in respect of any claim, issue, or matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the Court of Chancery or the court in which
such action or suit was brought shall determine upon application that, despite
the adjudication of liability but in view of all the circumstances of the case,
such person is fairly and reasonably entitled to indemnity for such expenses as
the Court of Chancery or such other court shall deem proper.

                 SECTION 10.03. Mandatory Indemnification. To the extent that a
director, officer, employee, or agent of the corporation has been successful on
the merits or otherwise in defense of any action, suit, or proceeding referred
to in Sections 10.01 and 10.02, or in defense of any claim, issue, or matter
therein, he shall be indemnified against expenses (including attorneys' fees)
actually and reasonably incurred by him in connection therewith.

                 SECTION 10.04. Determination of Conduct. The determination
that a director, officer, employee, or agent has met the applicable standard of
conduct set forth in Sections 10.01 and 10.02 (unless indemnification is
ordered by a court) shall be made (1) by the Board of Directors by a majority
vote of a quorum consisting of directors who were not parties to such action,
suit, or proceeding, or (2) if such quorum is not obtainable, or, even if
obtainable a quorum of disinterested directors so directs, by independent legal
counsel in a written opinion, or (3) by the stockholders.

                 SECTION 10.05. Payment of Expenses in Advance. Expenses
incurred in defending a civil or criminal action, suit, or proceeding shall be
paid by the corporation in advance of the final disposition of such action,
suit, or proceeding upon

                                      -12-
   13
receipt of an undertaking by or on behalf of the director, officer, employee,
or agent to repay such amount if it shall ultimately be determined that he is
not entitled to be indemnified by the corporation as authorized in this Article
X.

                 SECTION 10.06. Indemnity Not Exclusive. The indemnification
and advancement of expenses provided or granted hereunder shall not be deemed
exclusive of any other rights to which those seeking indemnification or
advancement of expenses may be entitled under the Certificate of Incorporation,
any other bylaw, agreement, vote of stockholders, or disinterested directors or
otherwise, both as to action in his official capacity and as to action in
another capacity while holding such office.

                 SECTION 10.07. Definitions. For purposes of this Article X:

                 (a)      "the corporation" shall include, in addition to the
         resulting corporation, any constituent corporation (including any
         constituent of a constituent) absorbed in a consolidation or merger
         that, if its separate existence had continued, would have had power
         and authority to indemnify its directors, officers, and employees or
         agents, so that any person who is or was a director, officer,
         employee, or agent of such constituent corporation, or is or was
         serving at the request of such constituent corporation as a director,
         officer, employee, or agent of another corporation, partnership, joint
         venture, trust, or other enterprise, shall stand in the same position
         under this Article X with respect to the resulting or surviving
         corporation as he would have with respect to such constituent
         corporation if its separate existence had continued;

                 (b)      "other enterprises" shall include employee benefit
         plans;

                 (c)      "fines" shall include any excise taxes assessed on a
         person with respect to any employee benefit plan;

                 (d)      "serving at the request of the corporation" shall
         include any service as a director, officer, employee, or agent of the
         corporation that imposes duties on, or involves services by, such
         director, officer, employee, or agent with respect to an employee
         benefit plan, its participants or beneficiaries; and

                 (e)      a person who acted in good faith and in a manner he
         reasonably believed to be in the interest of the participants and
         beneficiaries of an employee benefit plan shall be deemed to have
         acted in a manner "not opposed to the best interests of the
         corporation" as referred to in this Article X.

                 SECTION 10.08. Continuation of Indemnity. The indemnification
and advancement of expenses provided or granted hereunder shall, unless
otherwise provided when authorized or ratified, continue as to a person who has
ceased to be

                                      -13-
   14
a director, officer, employee, or agent and shall inure to the benefit of the
heirs, executors, and administrators of such a person.

                                   ARTICLE XI

                                 MISCELLANEOUS

                 SECTION 11.01. Seal. The corporate seal, if one is authorized
by the Board of Directors, shall have inscribed thereon the name of the
corporation, and the words "Corporate Seal, Delaware." The seal may be used by
causing it or a facsimile thereof to be impressed or affixed or otherwise
reproduced.

                 SECTION 11.02. Books. The books of the corporation may be kept
(subject to any provision contained in the statutes) outside the State of
Delaware at the offices of the corporation in Houston, Texas, or at such other
place or places as may be designated from time to time by the Board of
Directors.

                                  ARTICLE XII

                                   AMENDMENT

                 These bylaws may be altered, amended, or repealed by a
majority of the number of directors then constituting the Board of Directors at
