determining shareholders entitled to consent to that action, which record date
shall not precede, and shall not be more than ten 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 law or these bylaws,

writing without a meeting shall be the

purpose. The current number of directors is hereby set at nine. Each director

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 occurring other than by
reason of an increase in the number of directors shall be elected for the
unexpired term of his predecessor in office. A vacancy shall be deemed to exist
by reason of the death or resignation of the person elected, or upon the failure
of shareholders to elect directors to fill the unexpired terms of directors
removed in accordance with the provisions of Section 7 of this Article III.

be cast for the election of such director. The Board of Directors, by majority
vote, may also remove a director from office at any regular meeting by
resolution declaring the director's position vacant in the event the director,
in the Board's determination, has become incapacitated and cannot perform his or
her duties as director, or the director has been absent, without cause
considered adequate by the Board, from any two consecutive regular meetings of
the Board or from a total of four meetings in any 12-month period.

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

any document or instrument filed with the Secretary of State, and the execution
of such consent shall constitute attendance or presence in person at a meeting
of the Board of Directors or any such committee, as the case may be. Subject to
the requirement of the TBCA or these bylaws for notice of meetings, members of
the Board of Directors, or members of any committee designated by the Board of
Directors, may participate in and hold a meeting of the Board of Directors or
any committee of directors, as the case may be, by means of a conference

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

                                  ARTICLE VI

                         INDEMNIFICATION OF DIRECTORS,
                        OFFICERS, EMPLOYEES AND AGENTS

     SECTION 1. RIGHT TO INDEMNIFICATION. Subject to the limitations and
conditions as provided in this Article VI, and in Section 2.02-1 of the TBCA
(relating among other matters to liability for receipt of an improper personal
benefit or liability to the Corporation), as from time to time amended, each
person who was or is made a party or is threatened to be made a party to or is
involved in any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative, arbitrative or investigative
(hereinafter a "proceeding"), or any appeal in such a proceeding or any inquiry
or investigation that could lead to such a proceeding, by reason of the fact
that he or she, or a person of whom he or she is the legal representative, is or
was a director or officer of the Corporation or while a director or officer of
the Corporation is or was serving at the request of the Corporation as a
director, officer, partner, venturer, proprietor, trustee, employee, agent or
similar functionary of another foreign or domestic corporation, partnership,
joint venture, sole proprietorship, trust, employee benefit plan or other
enterprise shall be indemnified by the Corporation to the fullest extent
permitted by the TBCA as the same exists or may hereafter be amended against
judgments, penalties (including excise and similar taxes and punitive damages),
fines, settlements and reasonable expenses (including, without limitation,
attorneys' fees) actually incurred by such person in connection with such
proceeding, 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.

     SECTION 3. INDEMNIFICATION OF EMPLOYEES AND AGENTS. The Corporation, by
adoption of a resolution of the Board of Directors, may (but shall not be
required to) indemnify and advance expenses to an employee or agent of the
Corporation to the same extent and subject to the same conditions under which it
may indemnify and advance expenses to

                                       12


directors and officers under this Article VI; and, the Corporation may (but
shall not be required to) indemnify and advance expenses to persons who are not
or were not directors, officers, employees or agents of the Corporation but who
are or were serving at the request of the Corporation as a director, officer,
partner, venturer, proprietor, trustee, employee, agent or similar functionary
of another foreign or domestic corporation, partnership, joint venture, sole
proprietorship, trust, employee benefit plan and or other enterprise against any
liability asserted against that person and incurred by that person in such a
capacity or arising out of such individual's status as such a person to the same
extent that it may indemnify and advance expenses to directors under this
Article VI.

     SECTION 4. 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 5. 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
indemnified pursuant to Section 3 of this Article VI may have or hereafter
acquire under any law (common or statutory), provision of the Amended and
Restated Articles of Incorporation or these bylaws, agreement, vote of
shareholders or disinterested directors or otherwise.

     SECTION 6. INSURANCE. The Corporation may purchase and maintain insurance
and, to the extent permitted by the TBCA, similar arrangements, at its expense,
to protect itself and any person who is or was serving as a director, officer,
employee or agent of the Corporation or is or was serving at the request of the
Corporation as a director, officer, partner, venturer, proprietor, trustee,
employee, agent or similar functionary of another foreign or domestic
corporation, partnership, joint venture, proprietorship, employee benefit plan,
trust or other enterprise against any expense, liability 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 7. 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 shareholder's meeting or with
or before the next submission to shareholders of a consent to action without a
meeting.

     SECTION 8. 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
and to the fullest extent permitted by applicable law.

                                  ARTICLE VII

                                 CAPITAL STOCK

     SECTION 1. CERTIFICATES OF STOCK. The certificates for shares of the
capital stock of the Corporation shall be in such form, consistent with that
required by law and the Amended and Restated Articles of Incorporation, as shall
be approved by the Board of Directors. The Chairman of the Board, President or a
Vice President (if any) shall cause to be issued to each shareholder one or more
certificates, which shall be signed by (a) one of the chief executive officer,
President, or a Vice President and (b) one of the Chief Financial Officer,
Secretary, an Assistant Secretary, the Treasurer or an Assistant Treasurer
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 or all of 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 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 effect 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.

     SECTION 2. TRANSFER OF SHARES. The shares of stock of the Corporation 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 4 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 4 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 on 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. REGULATIONS REGARDING CERTIFICATES. The Board of Directors shall
have the power and authority to make all such rules and regulations as they may
deem expedient concerning the issuance, transfer and registration or the
replacement of certificates for shares of capital stock of the Corporation.

     SECTION 4. 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

                                       14


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.

established from time to time by the Board of Directors.

     SECTION 2. CORPORATE SEAL. The Board of Directors may provide a suitable
seal, containing the name of the Corporation. The Secretary shall have charge of

of the seal may be kept and used by the Treasurer, if any, or by any Assistant
Secretary or Assistant Treasurer.

     SECTION 3. NOTICE AND WAIVER OF NOTICE. Whenever any notice is required to
be given by law, the Amended and Restated Articles of Incorporation or these
bylaws, except with respect to notices of meetings of shareholders (with respect
to which the provisions of Article II, Section 6 apply) and except with respect
to notices of special meetings of the Board of Directors (with respect to which
the provisions of Article III, Section 6 apply), said notice shall be deemed to
be sufficient if given (a) by telegraphic, cable, telecopy, facsimile,
electronic mail, or wireless transmission or (b) by deposit of same in a post
office box in a sealed prepaid wrapper addressed to the person entitled thereto
at his or her address as it appears on the records of the Corporation, and such
notice shall be deemed to have been given on the day of such transmission or
mailing, as the case may be.

                Whenever notice is required to be given by law, the Amended and
Restated 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 the notice required to be given by law,
the Amended and Restated Articles of Incorporation or these bylaws, as the case
may be.

     SECTION 4. RESIGNATIONS. Any director, member of a committee or officer may
resign at any time. Such resignation shall be made in writing and shall take
effect at the time specified therein, or if no time be specified, at the time of
its receipt by the chief executive officer or Secretary. The acceptance of a
resignation shall not be necessary to make it effective, unless expressly so
provided in the resignation.

     SECTION 5. FACSIMILE SIGNATURES. In addition to the provisions for the use
of facsimile signatures elsewhere specifically authorized in these bylaws,
facsimile signatures of any officer or officers of the Corporation may be used
whenever and as authorized by the Board of Directors.

     SECTION 6. BOOKS AND RECORDS. The Corporation shall keep books and records
of account and shall keep minutes of the proceedings of its shareholders, its
Board of Directors and each committee of its Board of Directors. The Corporation
shall keep at its registered office or principal place of business, or at the
office of its transfer agent or registrar, a record of the

                                       15


original issuance of shares issued by the Corporation and a record of each
transfer of those shares that have been presented to the Corporation for
registration of transfer. Such records shall contain the names and addresses of
all past and current shareholders of the Corporation and the number and class of
shares issued by the Corporation held by each of them. Any books, records,
minutes and share transfer records may be in written form or in any other form
capable of being converted into written form within a reasonable time.

     SECTION 7. AMENDMENT OF BYLAWS. No provision of the Corporation's bylaws
which has been adopted by the shareholders may be amended, modified or repealed,
except by the vote of a majority of the shareholders. No bylaw provision which
conflicts with or is contrary to a bylaw adopted by the shareholders may be
adopted, except by the vote of a majority of the shareholders. Except as
otherwise provided in this Section 7, the power to alter, amend or repeal the
bylaws or adopt new bylaws shall be vested in the Board of Directors.
