located at 2001 S.E. Evangeline Thruway, Lafayette, Louisiana 70508.

         1.2 ADDITIONAL OFFICES. The Corporation may have such offices at such
other places as the Corporation's Board of Directors (the "Board") may from time
to time determine or the business of the Corporation may require.

                        SECTION 2. SHAREHOLDERS MEETINGS

         2.1 PLACE OF MEETINGS. Unless otherwise required by law or these
By-laws, all meetings of the shareholders shall be held at the principal office
of the Corporation or at such other place, within or without the State of
Louisiana, as may be designated by the Board.

         2.2 ANNUAL MEETINGS. An annual meeting of the shareholders shall be
held at such date at such time as may be specified by the Board in the call of
the meeting, for the purpose of electing directors and for the transaction of
such other business as may be properly brought before the meeting. If no annual
shareholders' meeting is held for a period of eighteen months, any shareholder
may call such meeting to be held at the registered office of the Corporation as
shown on the records of the Secretary of State of Louisiana.

         2.3 SPECIAL MEETINGS. Special meetings of the shareholders, for any
purpose or purposes, may be called by the Chairman of the Board, the Chief
Executive Officer or the Board, or by the shareholders as provided in the
Articles of Incorporation.

         2.4 NOTICE OF MEETINGS. Except as otherwise provided by law, the
authorized person or persons calling a shareholders' meeting shall cause written
notice of the time, place and purpose of the meeting to be given to all
shareholders entitled to vote at such meeting, at least ten days and not more
than sixty days prior to the day fixed for the meeting. Notice of the annual
meeting need not state the purpose or purposes thereof, unless action is to be
taken at the meeting as to which notice is required by law or the By-laws.


<PAGE>


Notice of a special meeting shall state the purpose or purposes thereof, and the
business conducted at any special meeting shall be limited to the purpose or
purposes stated in the notice.

         2.5 LIST OF SHAREHOLDERS. At every meeting of shareholders, a list of
shareholders entitled to vote, arranged alphabetically and certified by the
Corporation's Secretary or by the agent of the Corporation having charge of
transfers of shares, showing the number and class of shares held by each such
shareholder on the record date for the meeting, shall be produced on the request
of any shareholder.

         2.6 QUORUM. At all meetings of shareholders, the holders of a majority
of the total voting power of the Corporation shall constitute a quorum; provided
that this subsection shall not have the effect of reducing the vote required to
approve or affirm any matter that may be established by law, the Articles of
Incorporation or these By-laws.

         2.7 VOTING. When a quorum is present at any meeting a majority of the
total voting power shall decide each question brought before such meeting,
unless the question is one upon which, by express provision of law or the
Articles of Incorporation, a different vote is required, in which case such
express provision shall govern and control the decision of such question.
Directors shall be elected by plurality vote.

         2.8 PROXIES-GENERAL. At any meeting of the shareholders, every
shareholder having the right to vote shall be entitled to vote in person or by
proxy appointed by an instrument in writing executed by such shareholder and
bearing a date not more than eleven months prior to the meeting, unless the
instrument provides for a longer period, but in no case will an outstanding
proxy be valid for longer than three years from the date of its execution. The
person appointed as proxy need not be a shareholder of the Corporation.

         2.9 EXECUTION OF PROXIES. Any proxy must be executed by a shareholder
or the shareholder's authorized officer, director, employee or agent. Any
signature on a proxy may be affixed by any reasonable means, including but not
limited to facsimile signature.

         2.10 ELECTRONICALLY TRANSMITTED PROXIES. A shareholder may authorize
another person or persons to act for him as proxy by transmitting or authorizing
the transmission of a telegram, cablegram or other means of electronic
transmission to the person who will be the holder of the proxy or to a proxy
solicitation firm, proxy support service organization or similar agent duly
authorized by the person who will be the holder of the proxy to receive such


                                      -2-
<PAGE>


transmission; provided, however, that any such telegram, cablegram or other
means of electronic transmission shall be submitted with information from which
the Corporation may determine that the telegram, cablegram or other electronic
transmission was authorized by the shareholder. If it is determined that such
electronic transmissions are valid, the inspectors or other persons making that
determination shall specify the information upon which they relied.

         2.11 VALIDITY OF COPIES AND OTHER REPRODUCTIONS OF PROXIES. Any copy,
facsimile, telecommunication or other reliable reproduction of the writing or
transmission created pursuant hereto may be substituted or used in lieu of the
original writing or transmission for all purposes for which the original writing
or transmission could be used; provided, however, that such copy, facsimile
telecommunication or other reliable reproduction shall be a complete
reproduction of the entire original writing or transmission.

         2.12 VOTING POWER PRESENT OR REPRESENTED. For purposes of determining
the amount of voting power present or represented at any annual or special
meeting of shareholders with respect to voting on a particular proposal, shares
as to which the proxy holders have been instructed to abstain from voting on the
proposal, and shares that have been precluded from voting (whether by law,
regulations of the Securities and Exchange Commission, rules or by-laws of any
self-regulatory organization or otherwise), will not be treated as present; but
such shares will be counted as present for purposes of determining the existence
of a quorum.

         2.13 ADJOURNMENTS. Adjournments of any annual or special meeting of
shareholders may be taken without new notice being given unless a new record
date is fixed for the adjourned meeting, but any meeting at which directors are
to be elected shall be adjourned only from day to day until such directors shall
have been elected.

         2.14 WITHDRAWAL. If a quorum is present or represented at a duly
organized meeting, such meeting may continue to do business until adjournment,
notwithstanding the withdrawal of enough shareholders to leave less than a
quorum as fixed in Section 2.6 of these By-laws, or the refusal of any
shareholders present to vote.

         2.15 LACK OF QUORUM. If a meeting cannot be organized because a quorum
has not attended, those present may adjourn the meeting to such time and place
as they may determine, subject, however, to the provisions of Section 73C of the
Business Corporation Law of Louisiana. In the case of any meeting called for the
election of directors, those who attend the second of such


                                      -3-
<PAGE>


adjourned meetings, although less than a quorum as fixed in Section 2.6 hereof,
shall nevertheless constitute a quorum for the purpose of electing directors.

         2.16 PRESIDING OFFICER. The Chairman, the Chief Executive Officer and
the President, in that order, or in their absence, a chairman designated by the
Board, shall preside at all shareholders' meetings.

         2.17 DEFINITIONS OF SHAREHOLDER, VOTING POWER AND VOTING POWER PRESENT.

         Corporation not later than the close of business on the 60th day nor

     brought before the meeting pursuant to the Corporation's notice of meeting.

              (c) General.

                  (1) Only such business shall be conducted at a meeting of
         stockholders as shall have been brought before the meeting in
         accordance with the procedures set forth in this By-Law. Except as
         otherwise provided by law, the Articles of Incorporation or these
         By-Laws, the Chairman of the meeting shall have the power and duty to
         determine whether any business proposed to be brought before the
         meeting was proposed, in accordance with the procedures set forth in
         this By-Law and, if any proposed business is not in compliance with
         this By-Law, to declare that such defective proposal shall be
         disregarded.

                  (2) For purposes of this By-Law, "public announcement" shall
         mean disclosure in a press release reported by the Dow Jones News
         Service, Associated Press or comparable national news service or in a
         document publicly filed by the Corporation with the

<PAGE>


         Securities and Exchange Commission pursuant to Section 13, 14 or 15(d)
         of the Exchange Act.

                  (3) Notwithstanding the foregoing provisions of this By-Law, a
         stockholder shall also comply with all applicable requirements of the
         Securities Exchange Act of 1934 and the rules and regulations
         thereunder with respect to the matters set forth in this By-Law.
         Nothing in this By-Law shall be deemed to affect any rights (i) of
         stockholders to request inclusion of proposals in the Corporation's
         proxy statement pursuant to Rule 14a-8 under the Securities Exchange
         Act of 1934 or (ii) of the holders of any series of Preferred Stock to
         elect directors under specified circumstances.

                              SECTION 3. DIRECTORS

         3.1 POWERS; NUMBER. All of the corporate powers shall be vested in, and
the business and affairs of the Corporation shall be managed by, the Board,
which shall consist of four natural persons; provided that, if after proxy
material for any meeting of shareholders at which directors are to be elected
are mailed to shareholders, any person or persons named therein to be nominated
at the direction of the Board becomes unable or unwilling to serve, the
foregoing number of authorized directors shall be automatically reduced by a
number equal to the number of such persons unless the Board, by a majority vote
of the entire Board, selects an additional nominee; provided that in no event
shall the number of directors so authorized, nominated and elected be less than
the number required by law. No amendment to this Section to decrease the number
of directors shall shorten the term of any incumbent director. No director need
be a shareholder.

         3.2 POWERS. The Board may exercise all such powers of the Corporation
and do all such lawful acts and things that are not by law, the Articles of
Incorporation or these By-laws directed or required to be done by the
shareholders.

         3.3 GENERAL ELECTION. At each annual meeting of shareholders, directors
shall be elected to succeed those directors whose terms then expire. Such newly
elected directors shall serve until the next succeeding annual meeting of
shareholders after their election and until their successors are elected and
qualified. A director elected to fill a vacancy shall hold office for a term
expiring at the next annual meeting and until his successor is elected and
qualified. No decrease in the number of directors constituting the Board shall
shorten the term of any incumbent director.


                                      -6-
<PAGE>


         3.4 VACANCIES. Except as otherwise provided in the Articles of
Incorporation or these By-laws (a) the office of a director shall become vacant
if he dies, resigns or is removed from office and (b) the Board may declare
vacant the office of a director if he (i) is interdicted or adjudicated an
incompetent, (ii) is adjudicated a bankrupt, (iii) in the sole opinion of the
Board becomes incapacitated by illness or other infirmity so that he is unable
to perform his duties for a period of six months or longer, or (iv) ceases at
any time to have the qualifications required by law, the Articles of
Incorporation or these By-laws.

         3.5 FILLING VACANCIES. In the event of a vacancy (including any vacancy
resulting from an increase in the authorized number of directors, or from
failure of the shareholders to elect the full number of authorized directors),
the remaining directors, even though not constituting a quorum, may fill any
vacancy on the Board for the unexpired term by a majority vote of the directors
remaining in office, provided that the shareholders shall have the right, at any
special meeting called for the purpose prior to such action by the Board, to
fill the vacancy.

         3.6 NOTICE OF SHAREHOLDER NOMINEES. Only persons who are nominated in
accordance with the procedures set forth in this Section 3.6 shall be eligible
for election as directors. Nominations of persons for election to the Board may
be made at a meeting of shareholders by or at the direction of the Board or by a
shareholder entitled to vote for the election of directors at the meeting who
complies with the notice procedures set forth in this Section 3.6. Such
nominations, other than those made by or at the direction of the Board, shall be
made pursuant to timely notice in writing to the Corporation's Secretary. To be
timely, a shareholder's notice must be delivered or mailed and received at the
principal executive offices of the Corporation not less than 45 days nor more
than 90 days prior to the meeting; provided, however, that if less than 55 days
notice or prior public disclosure of the date of the meeting is given or made to
shareholders, notice by the shareholder to be timely must be received no later
than the close of business on the 10th day following the day on which such
notice of the date of the meeting was mailed or such public disclosure was made.
Such shareholder's notice shall set forth the following:

                  (a) as to each person whom the shareholder proposes to
         nominate for election or e-election as a director (i) the name, age,
         business address and residence address of such person, (ii) the
         principal occupation or employment of such person, (iii) the class and
         number of shares of the capital stock of the Corporation of which such
         person is the beneficial owner and the number of votes such person is
         entitled to cast at the shareholders' meeting and (iv) any other
         information relating to such person that would be required to be
         disclosed in solicitations of proxies for


                                      -7-
<PAGE>


         election of directors, or would be otherwise required, in each case
         pursuant to Regulation 14A under the Securities Exchange Act of 1934,
         as amended (including without limitation such person's written consent
         to being named in the proxy statement as a nominee and to serving as a
         director if elected); and

                  (b) as to the shareholder giving the notice (i) the name and
         address of such shareholder and (b) the class and number of shares of
         the capital stock of the Corporation of which such shareholder is the
         beneficial owner and the number of votes such person is entitled to
         cast at the shareholders' meeting. If requested in writing by the
         Corporation's Secretary at least 15 days in advance of the meeting,
         such shareholder shall disclose to the Secretary, within 10 days of
         such request, whether such person is the sole beneficial owner of the
         shares held of record by him; and, if not, the name and address of each
         other person known by the shareholder of record to claim a beneficial
         interest in such shares.

At the request of the Board, any person nominated by or at the direction of the
Board for election as a director shall furnish to the Corporation's Secretary
that information required to be set forth in a shareholder's notice of
nomination that pertains to the nominee. If a shareholder seeks to nominate one
or more persons as directors, the Secretary shall appoint two inspectors (the
"Inspectors"), who shall not be affiliated with the Corporation, to determine
whether a shareholder has complied with this Section 3.6. If the Inspectors
shall determine that a shareholder has not complied with this Section 3.6, the
Inspectors shall direct the chairman of the meeting to declare to the meeting
that a nomination was not made in accordance with the procedures prescribed by
the Articles of Incorporation or these By-laws; and the chairman shall so
declare to the meeting and the defective nomination shall be disregarded.

         3.7 COMPENSATION OF DIRECTORS. Directors as such, shall receive such
compensation for their services as may be fixed by resolution of the Board and
shall receive their actual expenses of attendance, if any, for each regular or
special meeting of the Board; provided that nothing herein contained shall be
construed to preclude any director from serving the Corporation in any other
capacity and receiving compensation therefor.

                        SECTION 4. MEETINGS OF THE BOARD

         4.1 PLACE OF MEETINGS. The meetings of the Board may be held at such
place within or without the State of Louisiana as a majority of the directors
may from time to time appoint.


                                      -8-
<PAGE>


         4.2 INITIAL MEETINGS. The first meeting of each newly elected Board
shall be held immediately following the shareholders' meeting at which the Board
is elected and at the same place as such meeting, and no notice of such first
meeting shall be necessary for the newly elected directors in order legally to
constitute the meeting.

         4.3 REGULAR MEETINGS; NOTICE. Regular meetings of the Board may be held
at such times as the Board may from time to time determine. No notice of regular
meetings of the Board shall be required provided that the date, time and place
of regular meetings are fixed by the Board.

         4.4 SPECIAL MEETINGS; NOTICE. Special meetings of the Board may be
called by the Chairman on reasonable notice given to each director, either
personally or by telephone, mail, e-mail or by telegram. Special meetings shall
be called by the Secretary in like manner and on like notice on the written
request of a majority of the directors, and if such officer fails or refuses, or
is unable within 24 hours to call a meeting when requested, then the directors
making the request may call the meeting on two days' written notice given to
each director. The notice of a special meeting of directors need not state its
purpose or purposes, but if the notice states a purpose or purposes and does not
state a further purpose to consider such other business as may properly come
before the meeting, the business to be conducted at the special meeting shall be
limited to the purposes stated in the notice.

         4.5 WAIVER OF NOTICE. Directors present at any regular or special
meeting shall be deemed to have received due, or to have waived, notice thereof,
provided that a director who participates in a meeting by telephone (as
permitted by Section 4.9) shall not be deemed to have received or waived due
notice if, at the beginning of the meeting, he objects to the transaction of any
business because the meeting is not lawfully called.

         4.6 QUORUM. A majority of the Board shall be necessary to constitute a
quorum for the transaction of business, and except as otherwise provided by law
or the Articles of Incorporation or these By-laws, the acts of a majority of the
Board at a meeting at which a quorum is present shall be the acts of the Board.
If a quorum is not present at any meeting of the Board, the directors present
may adjourn the meeting from time to time without notice other than announcement
at the meeting, until a quorum is present.

         4.7 WITHDRAWAL. If a quorum is present when the meeting convened, the
directors present may continue to do business, taking action by vote of a
majority of a quorum as fixed in Section 4.6, until adjournment,


                                      -9-
<PAGE>


notwithstanding the withdrawal of enough directors to leave less than a quorum
as fixed in Section 4.6 or the refusal of any director present to vote.

         4.8 ACTION BY CONSENT. Any action that may be taken at a meeting of the
Board or any committee thereof, may be taken by a consent in writing signed by
all of the directors or by all members of the committee, as the case may be, and
filed with the records of proceedings of the Board or such committee.

         4.9 MEETINGS BY TELEPHONE OR SIMILAR COMMUNICATION. Members of the
Board may participate at and be present at any meeting of the Board or any
committee thereof by means of conference telephone or similar communications
equipment if all persons participating in such meeting can hear and communicate
with each other. Participation in a meeting pursuant to this Section 4.9 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.

                       SECTION 5. COMMITTEES OF THE BOARD

         5.1 GENERAL. The Board may designate one or more committees, each
committee to consist of two or more of the directors (and one or more directors
may be named as alternate members to replace any absent or disqualified regular
members), which, to the extent provided by resolution of the Board or the
By-laws, shall have and may exercise the powers of the Board in the management
of the business and affairs of the Corporation, and may have power to authorize
the seal of the Corporation to be affixed to documents, but no such committee
shall have power or authority in reference to amending the Articles of
Incorporation, adopting an agreement of merger, consolidation, or share
exchange, recommending to the shareholders the sale, lease or exchange of all or
substantially all of the corporation's property and assets, recommending to the
stockholders a dissolution of the Corporation or a revocation of dissolution,
removing or indemnifying directors or amending the By-laws; and unless the
resolution expressly so provides, no such committee shall have the power or
authority to declare a dividend or authorize the issuance of stock. Such
committee or committees shall have such name or names as may be stated in the
By-laws, or as may be determined, from time to time, by the Board. Any vacancy
occurring in any such committee shall be filled by the Board, but the Chairman
of the Board may designate another director to serve on the committee pending
action by the Board. Each such member of a committee shall hold office during
the term of the Board constituting it, unless otherwise ordered by the Board.

         5.2 COMPENSATION COMMITTEE. The Board shall establish a Compensation
Committee consisting of at least two directors each of whom shall (i) be a
"non-employee director" as defined in Rule 16b-3 under the Securities Exchange
Act of 1934, and (ii) not serve, and shall not have served in the past, as an

consisting of at least a majority of directors who are not officers or employees
of the Corporation or any of its affiliates, and who meet the qualifications of
the NASDAQ Stock Market. The Audit Committee shall have such responsibilities
and authority as is contained in a written Audit Committee Charter approved from
time to time by the Board.

         5.4 PROCEDURES FOR COMMITTEES. Each committee shall keep written
minutes of its meetings and all actions taken by a committee shall be reported
to the Board at its next meeting, whether regular or special. Failure to keep
written minutes or to make such reports shall not affect the validity of action
taken by a committee. Each committee shall adopt such rules (not inconsistent
with the Articles of Incorporation, these By-laws or any regulations specified
for such committee by the Board) as it shall deem necessary for the proper
conduct of its functions and the performance of its responsibilities.

                       SECTION 6. REMOVAL OF BOARD MEMBER

         Any director or the entire Board may be removed at any time by the
affirmative vote of not less than a majority of the total voting power at a
meeting of shareholders duly called for that purpose. The shareholders at such
meeting may proceed to elect a successor or successors for the unexpired term of
the director or directors removed. Except as provided in this Section 6,
directors shall not be subject to removal.

                               SECTION 7. NOTICES

         7.1 FORM OF DELIVERY. Whenever under the provisions of law the Articles
of Incorporation or these By-laws notice is required to be given to any
shareholder or director, it shall not be construed to mean personal notice
unless otherwise specifically provided in the Articles of Incorporation or these
By-laws, but such notice may be given by mail, addressed to such shareholder or
director at his address as it appears on the records of the Corporation, with
postage thereon prepaid. Such notices shall be deemed to have been given at the
time


                                      -11-

they are deposited in the United States mail. Notice to a director pursuant to
Section 4.4 hereof may also be given personally or by telephone, e-mail or
telegram sent to his or her address as it appears on the Corporation's records.

         7.2 WAIVER. Whenever any notice is required to be given by law, the
Articles of Incorporation or these By-laws, a waiver thereof in writing signed
by the person or persons entitled to said notice, whether before or after the
time stated therein, shall be deemed equivalent thereto. In addition, notice
shall be deemed to have been given to, or waived by, any shareholder or director
who attends a meeting of shareholders or directors in person, or is represented
at such meeting by proxy, without protesting at the commencement of the meeting
the transaction of any business because the meeting is not lawfully called or
convened.

                              SECTION 8. OFFICERS

         8.1 DESIGNATIONS. The Corporation's officers shall be a Chairman, a
Chief Executive Officer, a President, a Secretary, a Chief Financial Officer, a
Controller and a Treasurer. The Corporation may also have one or more Assistant
Secretaries and Assistant Treasurers and other officers. Any two offices may be
held by one person, provided that no person holding more than one office may
sign, in more than one capacity, any certificate or other instrument required by
law to be signed by two officers.

         8.2 APPOINTMENT OF CERTAIN OFFICERS. At the first meeting of each newly
elected Board, or at such other time when there shall be a vacancy, the Board
shall elect the Corporation's officers.

her election, the Chief Executive Officer may appoint one or more Assistant
Secretaries, Assistant Treasurers and other officers. The Chief Executive
Officer shall, following such appointment or appointments, cause to be filed
with the minutes of the meeting of the Board an instrument specifying the
officers selected. The Chief Executive Officer may also appoint such other
employees and agents of the Corporation as he or she may deem necessary, or may
vest the authority to appoint such other employees and agents in such other of
the Corporation's officers as he or she deems appropriate subject in all cases
to his or her discretion. Whenever by law or the terms of the instrument, a
vice-president is necessary to execute any instrument in the absence of
execution by the Chief Executive Officer or the President, then the Chief
Financial Officer and any officer designated as a Director of a particular
function or designated in a specific grant of authority, shall be deemed a
vice-president of the Corporation for such purpose. Subject to these By-laws,
all of the officers, employees and


                                      -12-

Board, the Chief Executive Officer.

         8.4 REMOVAL. The Board or, except with respect to the Chairman of the
Board, the Chief Executive Officer may remove any officer with or without cause
at any time. Any such removal shall be without prejudice to the contractual
rights of such officers, if any, with the Corporation, but the election of an
officer shall not in and of itself create contractual rights. Any vacancy
occurring in any office of the Corporation, other than Chairman of the Board, by
death, resignation, removal or otherwise may be filled by the Chief Executive
Officer until the next regular or special meeting of the Board.

         8.5 THE CHIEF EXECUTIVE OFFICER. The Chief Executive Officer shall have
general and active responsibility for the management of the Corporation's
business, shall be responsible for implementing all orders and resolutions of
the Board, shall supervise the daily operations of the Corporation's business
and shall, in the absence of the Chairman, preside at meetings of the Board and
of the shareholders.

         8.6 AUTHORITY AND DUTIES OF OFFICERS. In the absence or disability of
the Chief Executive Officer, the President shall perform the duties and exercise
the powers of the Chief Executive Officer, and shall perform such other duties
as the Board shall prescribe.

         8.7 THE SECRETARY. The Secretary shall attend all meetings of the Board
and all meetings of the shareholders, record all votes and the minutes of all
proceedings in a book to be kept for that purpose, give, or cause to be given,
notice of all meetings of the shareholders and special meetings of the Board,
and perform such other duties as may be prescribed by the Board or Chief
Executive Officer. The Secretary shall also keep in safe custody the
Corporation's seal, if any, and affix the seal to any instrument requiring it.

         8.8 THE PRESIDENT. The President shall report to the Chief Executive
Officer and the Board and shall perform such duties as may be requested from
time to time by the Board, the Chief Executive Officer, or the By-laws.

         8.9 THE CHIEF FINANCIAL OFFICER. The Chief Financial Officer shall be

responsible for the Corporation's financial affairs. The Chief

<PAGE>


Financial Officer may sign, execute and deliver in the name of the Corporation
contracts, bonds and other obligations, shall be responsible for all of the
Corporation's internal and external financial reporting and shall perform such
other duties as may be prescribed from time to time by the Board, the Chief
Executive Officer or the By-laws.

         8.10 THE TREASURER. As directed by the Chief Financial Officer, the
Treasurer shall have general custody of all funds and securities of the
Corporation. The Treasurer may sign, with the Chief Executive Officer, the
President, the Chief Financial Officer or such other person or persons as may be
designated for the purpose by the Board, all bills of exchange or promissory
notes of the Corporation. The Treasurer shall perform such other duties as may
be prescribed from time to time by the Chief Financial Officer or the By-laws.

         8.11 THE CONTROLLER. The Controller shall assist the Chief Financial
Officer as directed in accounting, financial reporting, bookkeeping and
accounting procedures and perform such other duties as may be prescribed from
time to time by the Chief Financial Officer.

                                SECTION 9. STOCK

         9.1 CERTIFICATES. Every holder of stock in the Corporation shall be
entitled to have a certificate signed by the President and the Secretary or an
Assistant Secretary evidencing the number and class (and series, if any) of
shares owned by him, containing such information as required by law and bearing
the seal of the Corporation. If any stock certificate is manually signed by a
transfer agent or registrar other than the Corporation itself or an employee of
the Corporation, the signature of any such officer may be a facsimile. In case
any officer, transfer agent or registrar who has signed or whose facsimile
signature has been placed upon a certificate shall have ceased to be such
officer, transfer agent or registrar before such certificate is issued, it may
be issued by the Corporation with the same effect as if he were such officer,
transfer agent or registrar at the date of issue.

         9.2 MISSING CERTIFICATES. The President 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. As a condition
precedent to the issuance of a new certificate or certificates, the officers of
the Corporation shall, unless dispensed with by the President, require the owner
of such lost, stolen or destroyed certificate or certificates, or his legal
representative, (i) to advertise or give the Corporation a bond or (ii) enter
into a written indemnity


                                      -14-
<PAGE>


agreement, in each case in an amount appropriate to indemnify the Corporation
against any claim that may be made against the Corporation with respect to the
certificate alleged to have been lost, stolen or destroyed.

         9.3 TRANSFERS. Upon surrender to the Corporation or the transfer agent
of the Corporation, of a certificate for shares duly endorsed or 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.

                   SECTION 10. DETERMINATION OF SHAREHOLDERS

         10.1 RECORD DATE. For the purpose of determining shareholders entitled
to notice of and to vote at a meeting, or to receive a dividend, or to receive
or exercise subscription or other rights, or to participate in a
reclassification of stock, or in order to make a determination of shareholders
for any other proper purpose, the Board may fix in advance a record date for
determination of shareholders for such purpose, such date to be not more than
sixty days and, if fixed for the purpose of determining shareholders entitled to
notice of and to vote at a meeting, not less than ten days, prior to the date on
which the action requiring the determination of shareholder is to be taken.

         10.2 REGISTERED SHAREHOLDERS. Except as otherwise provided by law, the
Corporation, and its directors, officers and agents may recognize and treat a
person registered on its records as the owner of shares, as the owner in fact
thereof for all purposes, and as the person exclusively entitled to have and to
exercise all rights and privileges incident to the ownership of such shares, and
rights under this Section 10.2 shall not be affected by any actual constructive
notice that the Corporation, or any of its directors, officers or agents, may
have to the contrary.

Corporation shall be signed by such officer or officers or such other person or


                                      -15-

persons as the Chief Executive Officer or the Board may from time to time

         11.3 FISCAL YEAR. The Board may adopt for and on behalf of the
Corporation a fiscal or a calendar year.

         11.4 SEAL. The Board may adopt a corporate seal, which seal shall have
inscribed thereon the name of the Corporation. The seal may be used by causing
it or a facsimile thereof to be impressed or affixed or reproduced or otherwise.
Failure to affix the seal shall not, however, affect the validity of any
instrument.

         11.5 GENDER. All pronouns and variations thereof used in these By-laws
shall be deemed to refer to the masculine, feminine or neuter gender, singular
or plural, as the identity of the person, persons, entity or entities referred
to require.

with any threatened, pending or completed claim, action, suit or proceeding,
whether criminal, civil, administrative or investigative, against such person or
as to which he or she is involved solely as a witness or person required to give
evidence because he or she is a director, officer or employee of the Corporation
or serves or served at the request of the Corporation with any other enterprise
as a director, officer or employee. For purposes of this Section 12, the term
"Corporation" shall include any predecessor of this Corporation and any

the Corporation in a consolidation or merger; the term "other enterprises" shall
include any corporation, partnership, joint venture, trust or employee benefit
plan; service "at the request of the Corporation" shall include service as a

assessed on a person with respect to an employee benefit plan shall be deemed to
be indemnifiable expenses; and action by a person with respect to an employee


                                      -16-

benefit plan that such person reasonably believes to be in the interest of the
