                                 RESTATED BYLAWS

                                       OF

                                 ZIX CORPORATION



                                    ARTICLE I

                                     Offices

         1. Principal Office. The principal office of the Corporation shall be
located in the City of Dallas, County of Dallas, State of Texas. The Corporation
also may 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.

         2. Registered Office. The registered office of the Corporation,
required by the Texas Business Corporation Act (the "Act") to be maintained in
the State of Texas, may be, but need not be, the same as its principal place of
business in the State of Texas or the business office of a domestic or foreign
corporation authorized to transact business in the State of Texas. The address
of the registered office of the corporation may be changed from time to time by
resolution of the Board of Directors.

                                   ARTICLE II

                                  Shareholders

         1. Time and Place of Meeting. Meetings of the shareholders shall be
held at such times and at such places, within or without the State of Texas, as
shall be determined by the Board of Directors.

         2. Annual Meetings. Annual meetings of shareholders shall be held on
such date and at such time and place during the fourth month of each fiscal year
(beginning in 1988) as shall be determined by the Board of Directors of the
Corporation, at which they shall elect a Board of Directors and transact such
other business as may properly be brought before the meeting. The date of the
annual meeting of the shareholders may be a date or time different than that set
forth above if the Board of Directors so determines and so states in the notice
of the meeting or in a duly executed waiver thereof.

         3. Special Meetings. Special meetings of the shareholders may be called
at any time by the President or the Board of Directors, and shall be called by
the President or the Secretary at the request in writing of a majority of the
Board of Directors or at the request in writing of the holders of not less than
ten percent (10%) of all the shares issued, outstanding and entitled to vote at
the meeting. Such request shall state the purpose or purposes of the proposed
meeting. Business transacted at special meetings shall be confined to the
purposes stated in the notice of the meeting.



        4. Notice. Written or printed notice stating the place, day and hour of
the meeting and, in 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
fifty (50) days before the date of the meeting, either personally or by mail, by
or at the discretion of the President, the Secretary, or the officer or person
calling the meeting, to each shareholder entitled to vote at such meeting. If
mailed, such notice shall be deemed to be delivered when deposited in the United
States mail addressed to the shareholder at his address as it appears on the
share transfer records of the Corporation.

        5. Closing of Share Transfer Records and Fixing Record Date. 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 of
shareholders), the Board of Directors of the Corporation 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 the 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 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 apply 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.

           Unless a record date shall have previously been fixed or determined
pursuant to this section, whenever action by shareholders is proposed to be
taken by consent in writing without a meeting of 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 this section, 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 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. If no record
date shall have been fixed by the Board of Directors and prior action of the
Board of Directors is required by this section, 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 such prior action.

                                       2



        6. Voting List. The officer or agent of the Corporation having charge of
the stock transfer books for shares of the Corporation shall make, at least ten
(10) days before each meeting of the 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 voting
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 the 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 examine such list or transfer books or to vote at any
meetings of shareholders.

        7. Quorum. A quorum shall be present at all meetings of shareholders for
the transaction of business if the holders of a majority of the issued and
outstanding shares entitled to vote are represented at the meeting in person or
by proxy, unless otherwise provided in the Articles of Incorporation or the Act.
However, the shareholders represented in person or by proxy at a meeting of
shareholders at which a quorum is not present may 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 represented in person or by proxy at that meeting. Once a
quorum is present at a meeting of shareholders, the shareholders represented in
person or by proxy at the meeting may conduct such business as may be properly
brought before the meeting until it is adjourned, and the subsequent withdrawal
from the meeting of any shareholder or the refusal of any shareholder
represented in person or by proxy to vote shall not affect the presence of a
quorum at the meeting.

        8. Voting. With respect to any matter, other than the election of
directors or a matter for which the affirmative vote of the holders of a
specified portion of the shares entitled to vote is required by this section,
the affirmative vote of the holders of a majority of the shares entitled to vote
on that matter and represented in person or by proxy at a meeting of
shareholders at which a quorum is present shall be the act of the shareholders.

           Directors shall be elected by a plurality of the votes cast by the
holders of shares entitled to vote in the election of directors at a meeting of
shareholders at which a quorum is present.

           Each shareholder shall at every meeting of the shareholders be
entitled to one vote in person or by proxy for each share having voting power
held by such shareholder, except to the extent that the voting rights of the
shares of any class or classes are limited or denied by the Articles of
Incorporation. At each election for directors every shareholder shall be
entitled to vote, in person or by proxy, the number of shares owned by him for
as many persons as there are directors to be elected and for whose election he
has a right to vote. Cumulative voting is prohibited by the Articles of
Incorporation. Every proxy must be executed in writing by the shareholder. A
telegram, telex, cablegram, or similar transmission by the shareholder, or a
photographic, photostatic, facsimile, or similar reproduction of a writing
executed by the shareholder, shall be treated as an execution in writing for
purposes of this section. No proxy shall be valid after eleven (11) months from
the date of its execution unless otherwise provided therein. Each proxy shall be
revocable unless expressly provided therein to be irrevocable or unless
otherwise made irrevocable by law.

           An irrevocable proxy, if noted conspicuously on the certificate
representing the shares that are subject to the irrevocable proxy, shall be
specifically enforceable against the holder of those shares or any successor or
transferee of the holder. Unless noted conspicuously on the certificate
representing the shares that are subject to the irrevocable proxy, an
irrevocable proxy, even though otherwise enforceable, is ineffective against a
transferee for value without actual knowledge of the existence of the
irrevocable proxy at the time of the transfer or against any subsequent
transferee (whether or not for value), but such an

                                       3



irrevocable proxy shall be specifically enforceable against any other person who
is not a transferee for value from and after the time that the person acquires
actual knowledge of the existence of the irrevocable proxy.

           Shares registered in the name of another corporation may be voted by
such officer, agent or proxy as the bylaws of such corporation may prescribe or,
in the absence of such provisions, as the board of directors of such corporation
may determine.

           Shares held by an administrator, executor, guardian or conservator
may be voted by him, either in person or by proxy, without a transfer of such
shares into his name. Shares standing in the name of a trustee may be voted by
him, either in person or by proxy, but no trustee shall be entitled to vote
shares held by him without a transfer of such shares into his name as trustee.

           Shares standing in the name of a receiver may be voted by such
receiver, and shares held by or under the control of a receiver may be voted by
such receiver without being transferred into his name, if such authority is
contained in an appropriate order of the court that appointed the receiver.

           A shareholder whose shares are pledged shall be entitled to vote such
shares until the shares have been transferred into the name of the pledgee, and
thereafter the pledgee shall be entitled to vote the shares so transferred.

           Shares of its own stock belonging to the Corporation or held by it in
a fiduciary capacity shall not be voted, directly or indirectly, at any meeting,
and shall not be counted in determining the total number of outstanding shares
at any given time.

        9. Action by Unanimous Consent. Any action required to be taken at any
annual or special meeting of shareholders, or any action which may be taken at
any annual or special meeting of shareholders, may be taken without a meeting,
without prior notice, and without a vote, if a consent or consents in writing,
setting forth the action so taken, shall have been signed by the holder or
holders of all the shares entitled to vote with respect to the action that is
the subject of the consent.

           Every written consent shall bear the date of signature of each
shareholder who signs the consent. No written consent shall be effective to take
the action that is the subject of the consent unless, within sixty (60) days
after the date of the earliest dated consent delivered to the corporation in the
manner required by this section, a consent or consents signed by the holder or
holders of shares having not less than the minimum number of votes that would be
necessary to take the action that is the subject of the consent are 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 meetings of shareholders are recorded. Delivery shall be
by hand or certified or registered mail, return receipt requested. Delivery to
the Corporation's principal place of business shall be addressed to the
President.

           A telegram, telex, cablegram, or similar transmission by a
shareholder, or a photographic, photostatic, facsimile, or similar reproduction
of a writing signed by a shareholder, shall be regarded as signed by the
shareholder for purposes of this section.

           Prompt notice of the taking of any action by shareholders without a
meeting by less than unanimous written consent shall be given to those
shareholders who did not consent in writing to the action.

           If any action by shareholders is taken by written consent, any
articles or documents filed with the Secretary of State of the State of Texas as
a result of the taking of the action shall state, in lieu of any

                                       4



statement required by this section or by the Act concerning any vote of
shareholders, that written consent has been given in accordance with the
provisions of this section and that any written notice required by this section
has been given.

        10. Presence at Meetings by Means of Communication Equipment.
Shareholders may participate in and hold a meeting of such shareholders by means
of conference telephone or similar communications equipment by means of which
all persons participating in the meeting can hear each other, and participation
in a meeting pursuant to this section shall constitute presence in person at
such meeting, except where a person participates in the meeting for the express
purpose of objecting to the transaction of any business on the ground that the
meeting is not lawfully called or convened.

                                   ARTICLE III

                                    Directors

        1.  Number of Directors. The number of directors of the Corporation
shall be fixed from time to time by resolution of the Board of Directors. Until
otherwise fixed by resolution of the Board of Directors, the number of directors
shall be six. No decrease in the number of directors shall have the effect of
reducing the term of any incumbent director. Directors shall be elected at the
annual meeting of the holders of shares entitled to vote in the election of
directors, except as provided in Section 2 of this Article III, and each
director shall hold office until (i) his successor is elected and qualified,
(ii) he dies, (iii) he resigns, or (iv) he is removed. Directors need not be
residents of the State of Texas or shareholders of the Corporation.

        2.  Vacancies. Subject to other provisions of this section, any vacancy
occurring in the Board of Directors may be filled by the affirmative vote of a
majority of the remaining directors, though the remaining directors may
constitute less than a quorum of the Board of Directors as fixed by Section 10
of this Article III. A director elected to fill a vacancy shall be elected for
the unexpired term of his predecessor in office. Any directorship to be filled
by reason of an increase in the number of directors may be filled by unanimous
vote of the existing directors; provided, however, that the Board of Directors
may not fill more than two (2) such directorships during the period between any
two (2) successive annual meetings of shareholders. Any vacancy occurring in the
Board of Directors or any directorship to be filled by reason of an increase in
the number of directors may be filled by election at an annual or special
meeting of the shareholders called for that purpose. Shareholders holding a
majority of the issued and outstanding shares entitled to vote may, at any time,
terminate the term of office of all or any of the directors, with or without
cause, by a vote at any annual or special meeting, or by written consent, signed
by the holders of all of such shares, and filed with the secretary or, in his
absence, with any other officer. Such removal shall be effective immediately
upon such shareholder action even if successors are not elected simultaneously,
and the vacancies on the Board of Directors caused by such action shall be
filled only by election by the shareholders. Furthermore, the Board of Directors
may, by the vote or by the written consent of 66% or more of the entire Board of
Directors, terminate the term of office of any director who was within the
previous 90 day period an employee of the Corporation (or one or more of its
affiliates) but who is no longer an employee of the Corporation or of any of its
affiliates. Such removal shall be effective immediately upon such action by the
Board of Directors even if a successor is not elected simultaneously.

        3.  General Powers.  The business of the Corporation shall be managed by
its Board of Directors, which may exercise all powers of the Corporation and do
all such lawful acts and things, as are not by the Act, the Articles of
Incorporation or these Bylaws directed or required to be exercised or done by
the shareholders.

                                       5



        4.  Place of Meetings.  The Board of Directors of the Corporation may
hold meetings, both regular and special, either within or without the State of
Texas.

        5.  Annual Meetings. The first meeting of each newly elected Board of
Directors shall be held, without further notice, immediately following the
annual meeting of shareholders at which such directors were elected, provided a
quorum shall be present. In the event such meeting is not held immediately
following the annual meeting, the meeting may be held at such time and place as
shall be specified in a notice given as hereinafter provided for special
meetings of the Board of Directors, or as shall be specified in a written waiver
of notice signed by all of the directors.

        6.  Regular Meetings. Regular meetings of the Board of Directors shall
be held without special notice at such time and at such place as shall from time
to time be determined by the Board of Directors.

        7.  Special Meetings. Special meetings of the Board of Directors may be
called by or at the request of the President, and shall be called by the
Secretary on the written request of a majority of the incumbent directors. The
person or persons authorized to call special meetings of the Board of Directors
may fix the place for holding any special meeting of the Board of Directors
called by them.

        8.  Notice of Special Meetings. Notice of any special meetings shall be
given at least forty-eight (48) hours prior thereto if given either personally
(including written notice delivered personally or telephone notice) or by
telegram, and at least one hundred twenty (120) hours prior thereto if given by
written notice mailed to each director at the address of his business or
residence. If mailed, the notice shall be deemed to be delivered when deposited
in the United States mail addressed, in the above-specified manner, with postage
thereon prepaid. If notice be given by telegram, such notice shall be deemed to
be delivered when the telegram is delivered to the telegraph company. 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 for such meeting.

        9.  Waiver of Notice. Any director may waive notice of any meeting, as
provided in Article IV, Section 2, of these Bylaws. The attendance of a director
at a meeting shall constitute a waiver of notice of such meeting, except where a
director attends a meeting for the express purpose of objecting to the
transaction of any business because the meeting is not lawfully called or
convened.

        10. Quorum and Voting. At all meetings of the Board of Directors, the
presence of a majority of the number of directors fixed by Article III, Section
1, of these Bylaws shall constitute a quorum for the transaction of business,
and the affirmative vote of at least 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 the Act, the Articles of
Incorporation or these Bylaws. If a quorum shall not be present at any meeting
of the Board of Directors, a majority of 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.

        11. Committees.  The Board of Directors by resolution passed by a
majority of the full Board of Directors may designate an Executive Committee, to
consist of two or more directors, one of whom shall be designated as Chairman
and shall preside at all meetings of such Executive Committee and at least one
of whom shall be a person other than an officer or employee of the Corporation
or its subsidiaries. The Board of Directors may also designate one or more
directors to be alternate members of such Executive Committee, who may, subject
to any limitations imposed by the Board of Directors, replace absent or
disqualified members at any meeting of the Executive Committee. At any meeting
of the Executive

                                       6



Committee a majority of the members of the Executive Committee shall constitute
a quorum for the transaction of business, and the act of a majority of the
members present at any meeting at which a quorum is present shall be the act of
the Executive Committee. To the extent provided in the resolution of the Board
of Directors, the Executive Committee shall have and may exercise all of the
authority of the Board of Directors, and shall have power to authorize the seal
of the corporation to be affixed to all papers which may require it, subject to
the limitations set forth in the Act, the Articles of Incorporation or these
Bylaws; provided, however, that the Executive Committee shall not have the
authority to authorize the issuance of shares of stock of the Corporation or to
declare dividends with respect to shares of stock of the Corporation. The
designation of such Executive Committee and the delegation thereto of authority
shall not operate to relieve the Board of Directors, or any member thereof, of
any responsibility imposed upon it or him by law. Meetings of the Executive
Committee may be called and notices given in the same manner as calling and
giving notice of special meetings of the Board of Directors. Any member of the
Executive Committee may be removed, for or without cause, by the affirmative
vote of a majority of the full Board of Directors. If any permanent vacancy or
vacancies occur in the Executive Committee, such vacancy or vacancies shall be
filled by the affirmative vote of a majority of the full Board of Directors.

            The Board of Directors by resolution passed by a majority of the
full Board of Directors may designate other committees, each committee to
consist of two or more directors, one of whom shall be designated as Chairman
and shall preside at all meetings of such committee. The Board of Directors may
also designate one or more directors to be alternate members of any committee,
who may, subject to any limitations imposed by the Board of Directors, replace
absent or disqualified members at any meeting of that committee. To the extent
provided in the resolution of the Board of Directors, the committees shall have
such power and authority and shall perform such functions as may be provided in
such resolution, subject to the limitations set forth in the Act, the Articles
of Incorporation or these Bylaws. At any meeting of the committee a majority of
the members of the committee shall constitute a quorum for the transaction of
business, and the act of a majority of the members present at any meeting at
which a quorum is present shall be the act of the committee. Such committee or
committees shall have such name or names as may be designated by the Board of
Directors.

            The Executive Committee and all other such committees shall keep
regular minutes of their proceedings and report the same to the Board of
Directors at the meeting of the Board of Directors next succeeding such action.

        12. Compensation of Directors. Directors, as such, shall not receive any
stated salary for their services, 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. Nothing herein
contained shall be construed to preclude any director from serving the
Corporation in any other capacity and receiving compensation therefor. Members
of any committee may, by resolution of the Board of Directors, be allowed like
compensation for attending meetings of such committee.

        13. Action by Unanimous Written Consent. Any action required or
permitted to be taken at any meeting of the Board of Directors or of a committee
designated by the Board of Directors may be taken without a meeting if a written
consent, setting forth the action so taken, is signed by all the members of the
Board of Directors or the committee, as the case may be, and such consent shall
have the same force and effect as a unanimous vote at a meeting.

        14. Presence at Meetings by Means of Communication Equipment. Members of
the Board of Directors of the Corporation or any committee designated by the
Board of Directors may participate in and hold a meeting of the Board of
Directors or such committee by means of conference telephone or similar

                                       7



communications equipment by means of which all persons participating in the
meeting can hear each other, and participation in a meeting pursuant to this
section shall constitute presence in person at such meeting, except where a
person participates in the meeting for the express purpose of objecting to the
transaction of any business on the ground that the meeting is not lawfully
called or convened.

                                   ARTICLE IV

                                     Notices

        1. Form of Notice. Whenever under the provisions of the Act, the
Articles of Incorporation or these Bylaws, notice is required to be given to any
director or shareholder, and no provision is made as to how such notice shall be
given, such notice shall be given in writing, by mail, postage prepaid,
addressed to such director or shareholder at such address as appears on the
books of the Corporation, provided that such notice as is required to be given
to any director also may be given either personally (including written notice
delivered personally or telephone notice) or by prepaid facsimile. Any notice
required or permitted to be given by mail shall be deemed to be given at the
time when the same is deposited in the United States mail addressed in the
above-specified manner, with postage thereon prepaid.

        2. Waiver. Whenever any notice is required to be given to any director
or shareholder of the Corporation under the provisions of the Act, the Articles
of Incorporation or these Bylaws, a waiver thereof in writing signed by the
person or persons entitled to such notice, whether before or after the time
stated in such notice, shall be equivalent to the giving of such notice.

                                    ARTICLE V

                                    Officers

        1. General. The elected officers of the Corporation shall be a
President, one or more Vice Presidents, with or without such descriptive titles
as the Board of Directors shall deem appropriate, a Secretary and a Treasurer.
The Board of Directors by resolution may also appoint one or more Assistant
Secretaries, Assistant Treasurers and such other officers and assistant officers
and agents as from time to time may appear to be necessary or advisable in the
conduct of the affairs of the Corporation. Any two or more offices may be held
by the same person.

        2. Election. The Board of Directors at its first meeting after each
annual meeting of the shareholders shall elect and appoint the officers to fill
the positions designated in Section 1 of this Article V. The Board of Directors
may appoint such other officers and agents as it shall deem necessary and may
determine the salaries of all officers and agents from time to time. The
officers shall hold office until their successors are chosen and qualified. Any
officer elected or appointed by the Board of Directors may be removed, for or
without cause, at any time by a majority vote of the directors present at a
meeting of the Board of Directors at which a quorum is present, when in its
judgment the best interest of the Corporation will be served thereby, but such
removal shall be without prejudice to the contract rights, if any, of the
persons 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.

                                       8



       3. Chairman of the Board. The Chairman of the Board shall be chosen from
among the directors. He shall preside at all meetings of the Board of Directors,
unless he shall be absent or unless he shall, at his election, designate the
President to preside in his stead, and shall have such incidental powers and
duties as are related to the conduct of such meetings. The Chairman of the Board
shall also be an ex-officio member of all standing committees.

        4. President. The President shall be the Chief Executive Officer of the
Corporation and shall be responsible for the operations and business affairs of
the Corporation. He shall preside at all meetings of the shareholders and of the

Board of Directors and committees thereof are carried into effect.

        5. Vice Presidents. The Vice President or, if there be more than one,

                                       9

                                   ARTICLE VI

                        Certificates Representing Shares

        1. Form of Certificates. The Corporation shall deliver certificates
representing all shares to which shareholders are entitled. Certificates
representing shares of the Corporation shall be in such form as shall be
determined by the Board of Directors and shall be numbered consecutively and
entered in the books of the Corporation as they are issued. Each certificate
shall state on the face thereof that the Corporation is organized under the laws
of the State of Texas; the name of the registered holder; the number, class of
shares and the designation of the series, if any, which said certificate
represents; and either the par value of the shares or a statement that the
shares are without par value. Each certificate shall also set forth on the back
thereof, a full or summary statement of matters required by the Act or the
Articles of Incorporation to be described on certificates representing shares,
and shall contain a statement on the face thereof referring to the matters set
forth on the back thereof. Certificates shall be signed by the President and the
Secretary or any Assistant Secretary, and may be sealed with the seal of the
Corporation or a facsimile thereof. If any certificate is countersigned by a
transfer agent or registered by a registrar, either of which is other than the
Corporation or an employee of the Corporation, the signatures of the
Corporation's officers may be facsimiles. In case any officer or officers who
have signed, or whose facsimile signature or signatures have been used on such
certificate or certificates, shall cease to be such officer or officers of the
Corporation, whether because of death, resignation or otherwise, before such
certificate or certificates have been delivered by the Corporation or its
agents, such certificate or certificates may be adopted, nevertheless, by the
Corporation and issued and delivered as though the person or persons who signed
the certificate or certificates or whose facsimile signature or signatures have
been used thereon had not ceased to be such officer or officers of the
Corporation.

                                       10



        2. Restrictions on Transferability of Shares. In the event any
restriction on the transfer, or registration of the transfer, of shares shall be
imposed or agreed to by the Corporation, as permitted by law, each certificate
representing shares so restricted shall conspicuously set forth a full or
summary statement of the restriction on the face of the certificate, or shall
set forth such statement on the back of the certificate and conspicuously refer
to the same on the face of the certificate, or shall conspicuously state on the
face or back of the certificate that such restriction exists pursuant to a
specified document and that the Corporation will furnish to the holder of the
certificate without charge upon written request to the Corporation at its
principal place of business or registered office a copy of the specified
document.

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

        4. Transfer of Shares. Shares of stock shall be transferable on the
books of the Corporation by the holder thereof in person or by his duly
authorized attorney. Subject to any restrictions on transfer set forth in the
Articles of Incorporation of the Corporation, these Bylaws or any agreement
among shareholders to which the Corporation is a party or has notice, upon
surrender to the Corporation or to the transfer agent of the Corporation of the
certificate representing shares duly endorsed or accompanied by proper evidence
of succession, assignment or authority to transfer, it shall be the duty of the
Corporation or the transfer agent of the Corporation to issue a new certificate
to the person entitled thereto, cancel the old certificate and record the
transaction upon its books.

        5. Registered Shareholders. The Corporation shall be entitled to
recognize the holder of record of any share or shares of 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 law.

                                   ARTICLE VII

                                 Indemnification

        1. Indemnity. Each person who was or is made a party or is threatened to
be made a party to or is otherwise involved in any action, suit, or proceeding,
whether civil, criminal, administrative, or investigative and including, without
limitation, any "proceeding" referred to in art. 2.02-1 of the Texas Business
Corporation Act (hereinafter 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 is or was serving at the request of
the Corporation as a director or officer of another corporation or of a
partnership, joint venture, trust, or other enterprise, including service with
respect to an employee benefit plan (hereinafter an "Indemnitee"), whether the
basis of such proceeding is alleged action in an official capacity as a director
or officer or in any other capacity while serving as a director of officer shall
be indemnified and held harmless by the Corporation to the fullest extent
authorized by the Texas Business Corporation Act or other applicable law of the
State of Texas, as the same exists or may hereafter be amended (but, in the case
of any

                                       11



such amendment, only to the extent that such amendment permits the Corporation
to provide broader indemnification rights than permitted prior thereto), against
all expense, liability, and loss (including, without limitation, attorneys'
fees, judgments, fines, ERISA excise taxes or penalties, and amounts paid or to
be paid in settlement) reasonably incurred or suffered by such Indemnitee in
connection therewith, and such indemnification shall continue as to an
Indemnitee who has ceased to be a director or officer and shall inure to the
benefit of the Indemnitee's heirs, executors, and administrators; provided,
however, that, except for a proceeding brought by an Indemnitee to enforce his
or her rights to indemnification, the Corporation shall indemnify any such
Indemnitee in connection with a proceeding (or part thereof) initiated by such
Indemnitee only if such proceeding (or part thereof) was authorized by the Board
of Directors of the Corporation. The right to indemnification conferred in this
Article VII shall be a contract right and shall include the right to be paid by
the Corporation the expenses incurred in defending any such proceeding in
advance of its final disposition (hereinafter an "advancement of expenses");
provided, however, that, if the Texas Business Corporation Act or other
applicable law of the State of Texas requires, an advancement of expenses
incurred by an Indemnitee in his or her capacity as a director of officer (and
not in any other capacity in which service was or is rendered by such
Indemnitee, including, without limitation, service to an employee benefit plan)
shall be made only upon delivery to the Corporation of an undertaking complying
in all respects with the requirements of the Texas Business Corporation Act or
other applicable law of the State of Texas (hereinafter an "undertaking"), by or
on behalf of such Indemnitee, to repay all amounts so advanced if it shall
ultimately be determined by final judicial decision from which there is no
further right to appeal (hereinafter a "final adjudication") that such
Indemnitee is not entitled to be indemnified for such expenses under this
Article VII or otherwise. If the Corporation makes an advancement of expenses to
an Indemnitee, the Corporation shall be subrogated to every right of recovery
the Indemnitee may have against any insurance carrier from whom the Corporation
has purchased insurance for such purpose.

     2.   Remedy. If a claim under this Article VII is not paid in full by the
Corporation within 60 days after a written claim has been received by the
Corporation, the Indemnitee may at any time thereafter bring suit against the
Corporation to recover the unpaid amount of the claim. If successful in whole or
in part in any such suit, or in a suit by the Corporation to recover an
advancement of expenses pursuant to the terms of an undertaking, the Indemnitee
shall be entitled to be paid also the expense of prosecuting or defending such
suit, including, without limitation, any appeal. In (i) any suit brought by the
Indemnitee to enforce a right to indemnification (but not in a suit brought by
the Indemnitee to enforce a right to an advancement of expenses) it shall be a
defense that, and (ii) in any suit by the Corporation to recover an advancement
of expenses pursuant to the terms of an undertaking the Corporation shall be
entitled to recover such expenses upon a final adjudication that, the Indemnitee
has not met the applicable standard of conduct set forth in the Texas Business
Corporation Act or other applicable law of the State of Texas. Neither the
failure of the Corporation (including its Board of Directors, independent legal
counsel, or its shareholders) to have made a determination prior to the
commencement of such suit that the Indemnitee met the applicable standard of
conduct set forth in the Texas Business Corporation Act or other applicable law
of the State of Texas, nor an actual determination by the Corporation (including
its Board of Directors, independent legal counsel, or its shareholders) that the
Indemnitee has not met such applicable standard of conduct, shall create a
presumption that the Indemnitee has not met the applicable standard of conduct
or, in the case of such a suit brought by the Indemnitee, be a defense to such
suit. In any suit brought by the Indemnitee to enforce a right to
indemnification or to an advancement of expenses or by the Corporation to
recover an advancement of expenses pursuant to the terms of an undertaking, the
burden of proving that the Indemnitee is not entitled to be indemnified, or to
such advancement of expenses, under this Article VII or otherwise, shall be on
the Corporation.

     3.   Employees and Agents. The Corporation may, to the extent authorized
from time to time by the Board of Directors, grant rights to indemnification and
to the advancement of expenses to any employee

                                       12



or agent of the Corporation to the fullest extent of the provisions of this
Article VII with respect to the indemnification and advancement of expenses of
directors and officers of the Corporation.

        4.  Partial Indemnification; Interest.

        (A) If it is determined pursuant to the provisions of the Texas Business
Corporation Act or other applicable law of the State of Texas, or by the court
before which such action was brought, that an Indemnitee is entitled to
indemnification as to some claims, issues, or matters, but not as to other
claims, issues, or matters, involved in any action, no matter by whom brought,
the person or persons making such determination (or the court) shall authorize
the reasonable proration of such expenses, judgments, penalties, fines, and
amounts incurred in settlement with respect to which indemnification is sought
by the Indemnitee, among such claims, issues, or matters as the person or
persons making such determination (or the court) shall deem appropriate in light
of all of the circumstances of such action.

        (B) If it is determined pursuant to the provisions of the Texas Business
Corporation Act or other applicable law of the State of Texas, or by the court
before which such action was brought, that certain amounts incurred by the
Indemnitee are, for whatever reason, unreasonable in amount, the person or
persons making such determination (or the court) shall authorize indemnification
to be paid by the Corporation to the Indemnitee for only such amounts as the
person or persons making such determination (or the court) shall deem reasonable
in light of all of the circumstances of such action.

        (C) To the extent deemed appropriate pursuant to the provisions of the
Texas Business Corporation Act or other applicable law of the State of Texas, or
by the court before which such action was brought, interest shall be paid by the
Corporation to the Indemnitee, at a reasonable interest rate, for amounts for
which the Corporation indemnifies the Indemnitee.

        5.  Nonexclusivity. The right to indemnification and advancement of
expenses provided to an Indemnitee pursuant to this Article VII shall not be
deemed exclusive of any other rights to which the Indemnitee may be entitled
under any charter provision, bylaw, agreement, resolution, vote of shareholders
or disinterested directors, or otherwise, including, without limitation, under
the Texas Business Corporation Act or other applicable law of the State of
Texas, as then in effect, both as to acts in his or her official capacity and as
to acts in any other capacity.

        6.  Insurance.

        (A) The Corporation may purchase and maintain insurance on behalf of an
Indemnitee against any liability asserted against him or her or incurred by or
on behalf of him or her whether or not the Corporation would have the power to
indemnify him or her against such liability under the provisions of this Article
VII or under the Texas Business Corporation Act or other applicable law of the
State of Texas, as then in effect. The purchase and maintenance of such
insurance shall not in any way limit or affect the rights and obligations of the
Corporation or an Indemnitee under this Article VII and the adoption of this
Article VII by the Corporation shall not in any way limit or affect the rights
and obligations of the Corporation or of the other party or parties thereto
under any such policy or agreement of insurance.

        (B) If the Indemnitee shall receive payment from any insurance carrier
or from the plaintiff in any action against the Indemnitee in respect of
indemnified amounts after payments on account of all or part of such indemnified
amounts have been made by the Corporation pursuant to this Article VII, the
Indemnitee shall promptly reimburse the Corporation for the amount, if any, by
which the sum of such payment by such insurance carrier or such plaintiff and
payments by the Corporation to the Indemnitee exceeds such

                                       13



indemnified amounts; provided, however, that such portions, if any, of such
insurance proceeds that are required to be reimbursed to the insurance carrier
under the terms of its insurance policy, such as deductible or coinsurance
payments, shall not be deemed to be payments to the Indemnitee hereunder. In
addition, upon payment of indemnified amounts under this Article VII, the
Corporation shall be subrogated to the Indemnitee's rights against any insurance
carrier in respect of such indemnified amounts and the Indemnitee shall execute
and deliver any and all instruments and documents and perform any and all other
acts and deeds that the Corporation deems reasonably necessary or advisable to
secure such rights.

     7.   Witness Expenses. Upon an Indemnitee's written request, the
Corporation shall pay (in advance or otherwise) or reimburse any and all
expenses reasonably incurred by the Indemnitee in connection with his or her
appearance as a witness in any proceeding at a time when he has not been
formally named a defendant or respondent to such a proceeding.

     8.   Contribution. If the indemnity provided for in this Article VII is
unavailable to an Indemnitee for any reason whatsoever, the Corporation, in lieu
of indemnifying the Indemnitee, shall contribute to the amount reasonably
incurred by or on behalf of the Indemnitee, whether for judgments, fines,
penalties, amounts incurred in settlement, or for expenses in connection with
any proceeding, no matter by whom brought, in such proportion as deemed fair and
reasonable, by the person or persons entitled to make the determination as to
whether the Indemnitee has met the requisite standard of conduct under the Texas
Business Corporation Act or other applicable law of the State of Texas, or by
the court before which such proceeding was brought, taking into account all of
the circumstances of such proceeding, in order to reflect (i) the relative
benefits received by the Corporation and the Indemnitee as a result of the event
or transaction giving cause to such proceeding; and (ii) the relative fault of
the Corporation (and its other directors, officers, employees, and agents) and
the Indemnitee in connection with such event or transaction.

     9.   Severability. If any provision of this Article VII shall be deemed
invalid or inoperative, or if a court of competent jurisdiction determines that
any of the provisions of this Article VII contravenes public policy, this
Article VII shall be construed so that the remaining provisions shall not be
affected, but shall remain in full force and effect, and any such provisions
that are invalid and inoperative or contravene public policy shall be deemed,
without further action or deed on the part of any person, to be modified,
amended, or limited, but only to the extent necessary to render the same valid
and enforceable, and the Corporation shall indemnify the Indemnitee as to
expenses, judgments, fines, and amounts incurred in settlement with respect to
any proceeding, no matter by whom brought, to the full extent permitted by any
applicable provision of this Article VII that shall not have been invalidated
and to the full extent otherwise permitted.

                                  ARTICLE VIII

and paid in cash, in property, or in shares of the Corporation, provided that
all such declarations and payments of dividends shall be in strict compliance
with all applicable laws and the Articles of Incorporation. The Board may fix in
advance a record date for the purpose of determining shareholders entitled to
receive payment of any dividend, such record date to be not more than fifty (50)
days prior to the payment of such dividend. In the absence of any action by the
Board of Directors, the date upon which the Board of Directors adopts the
resolution declaring such dividend shall be the record date.

                                       14



     2.   Reserves. There may be created by resolution of the Board of Directors

any property of the Corporation, or for such other proper purposes as the Board
of Directors shall deem beneficial to the Corporation, and the Board of

other person or officer. Any person authorized to vote securities shall have the
power to appoint proxies with the general power of substitution.

     8.   Resignation. Any director, officer, employee or agent of the
