                             MEETING OF SHAREHOLDERS

         Section 1. ANNUAL  MEETING.  The annual meeting of the  shareholders of
Enzo Biochem,  Inc.,  (hereinafter called the "Corporation") for the election of
directors and for the  transaction of such other business as may come before the
meeting  shall  be held  during  the  sixth  month  following  the  close of the
Corporation's  fiscal year.  If the annual  meeting shall not be held on the day
hereinabove  provided  for,  the  Board  shall  call a special  meeting  for the
election of directors,  which meeting shall be held within two months after said
day.

         Section 2. SPECIAL  MEETINGS.  Except as otherwise  required by law and
subject  to the rights of the  holders of any class or series of stock  having a
preference  over  another  class or  series  of stock  as to  dividends  or upon
liquidation,  special  meetings of shareholders of the Corporation may be called
only by the Board pursuant to a resolution  approved by a majority of the entire
Board  (whether  or not  there  exist any  vacancies  in  previously  authorized
directorships  at the time any such  resolution  is  presented  to the Board for
adoption).

         Section 3. NOTICE OF  MEETINGS.  Notice of the place,  date and time of
the holding of each annual and special meeting of the  shareholders  and, in the
case of a special  meeting,  the  purpose or  purposes  thereof,  shall be given
personally or by mail in a postage prepaid envelope to each shareholder entitled
to vote at such  meeting,  not less than ten nor more than fifty days before the
date of such meeting,  and, if mailed,  it shall be directed to such shareholder
at his address as it appears on the records of the Corporation,  unless he shall
have filed with the Secretary of the Corporation, a written request that notices
to him be mailed to some other  address,  in which case, it shall be directed to
him at such other address.  Notice of any meeting of  shareholders  shall not be
required to be given to any  shareholder who shall attend such meeting in person
or by proxy and shall  not,  at the  beginning  of such  meeting,  object to the
transaction  of any  business  because  the  meeting is not  lawfully  called or
convened,  or who shall,  either  before or after the  meeting,  submit a signed
waiver of notice,  in person or by proxy.  Unless the Board  shall fix after the
adjournment a new record date for an adjourned meeting, notice of such adjourned
meeting  need not be given if the time and place to which the  meeting  shall be
adjourned  were announced at the meeting at which the



adjournment is taken. At the adjourned  meeting the Corporation may transact any
business  which  might have been  transacted  at the  original  meeting.  If the
adjournment  is for more than thirty  days,  or if after the  adjournment  a new
record  date is fixed  for the  adjourned  meeting,  a notice  of the  adjourned
meeting  shall be given to each  shareholder  of record  entitled to vote at the
meeting.

         Section 4. PLACE OF MEETINGS.  Meetings of the shareholders may be held
at such  place,  within or without the State of  incorporation,  as the Board or
other officer  calling the same shall specify in the notice of such meeting,  or
in a duly executed waiver of notice thereof.

         Section 5. QUORUM. At all meetings of the shareholders the holders of a
majority  of the votes of the  shares  of stock of the  Corporation  issued  and
outstanding  and  entitled  to vote  shall be  present  in person or by proxy to
constitute  a  quorum  for  the   transaction  of  any  business,   except  when
shareholders  are  required  to vote by class,  in which event a majority of the
issued  and  outstanding  shares of the  appropriate  class  shall be present in
person  or by proxy,  or  except as  otherwise  provided  by  statute  or in the
Certificate  of  Incorporation.  In the  absence of a quorum,  the  holders of a
majority  of the votes of the shares of stock  present in person or by proxy and
entitled to vote,  or if no  shareholder  entitled to vote is present,  then any
officer of the  Corporation  may adjourn the meeting  from time to time.  At any
such  adjourned  meeting at which a quorum may be present  any  business  may be
transacted which might have been transacted at the meeting as originally called.

         Section 6.  ORGANIZATION.  At each meeting of the  shareholders  of the
Corporation,  the Chairman of the Board,  or in his absence or inability to act,
the Vice  Chairman of the Board,  or in the absence or  inability  to act of the
Chairman of the Board and the Vice Chairman of the Board,  the President,  or in
the absence or inability to act of the Chairman of the Board,  the Vice Chairman
of the Board and the President,  a Vice  President,  or in the absence of all of
the foregoing,  any person chosen by a majority of those  shareholders  present,
shall act as  chairman  of the  meeting.  The  Secretary,  or, in his absence or
inability  to act,  the  Assistant  Secretary  or any  person  appointed  by the
chairman  of the  meeting,  shall act as  secretary  of the meeting and keep the
minutes thereof.

         Section 7. ORDER OF BUSINESS.  The order of business at all meetings of
the shareholders shall be as determined by the chairman of the meeting.

         Section  8.  VOTING.  Except as  otherwise  provided  by  statute,  the
Certificate of Incorporation, or any certificate duly filed in the office of the
Department  of State of the  State of  incorporation,  each  holder of record of
shares of stock of the Corporation having voting power shall be entitled at each
meeting of the  shareholders  to one vote for every share of such stock standing
in his name on the record of  shareholders  of the Corporation on the date fixed
by the Board as the record date for the  determination  of the  shareholders who
shall be  entitled to notice of and to vote at such  meeting;  or if such record
date shall not have been so fixed, then at the close of business on the day next
preceding  the day on which  notice  thereof  shall be  given,  or if  notice is
waived,  at the close of business on the



day next  preceding  the day on which the meeting is held;  or each  shareholder
entitled to vote at any meeting of the shareholders may authorize another person
or  persons  to act  for  him by a  proxy  signed  by  such  shareholder  or his
attorney-in-fact.  Any such proxy shall be  delivered  to the  secretary of such
meeting  at or prior to the time  designated  in the  order of  business  for so
delivering  such proxies.  No proxy shall be valid after the expiration of three
years from the date thereof, unless otherwise provided in the proxy. Every proxy
shall be revocable at the pleasure of the  shareholder  executing  it, except in
those cases where an irrevocable  proxy is permitted by law. Except as otherwise
provided by statute,  these By-Laws,  or the Certificate of  Incorporation,  any
corporate action to be taken by vote of the shareholders  shall be authorized by
a majority of the total  votes,  or when  shareholders  are  required to vote by
class by a majority of the votes of the appropriate  class, cast at a meeting of
shareholders  by the holders of shares present in person or represented by proxy
and entitled to vote on such action.  Unless required by statute,  or determined
by the chairman of the meeting to be  advisable,  the vote on any question  need
not be by written  ballot.  On a vote by written  ballot,  each ballot  shall be
signed by the shareholder  voting,  or by his proxy, if there be such proxy, and
shall state the number of shares voted.

         Section  9. LIST OF  SHAREHOLDERS.  The  officer  who has charge of the
stock  ledger of the  Corporation,  or the transfer  agent of the  Corporation's
stock,  if there be one then acting,  shall  prepare and make, at least ten days
before  every  meeting  of  shareholders,  a complete  list of the  shareholders
entitled to vote at the meeting, arranged in alphabetical order, and showing the
address of each  shareholder and the number of shares  registered in the name of
each shareholder. Such list shall be open to the examination of any shareholder,
for any purpose germane to the meeting,  during ordinary  business hours,  for a
period of at least ten days prior to the  meeting,  either at a place within the
city where the  meeting is to be held,  at the place  where the meeting is to be
held,  or at the office of the transfer  agent.  The list shall also be produced
and kept at the time and place of the meeting during the whole time thereof, and
may be inspected by any shareholder who is present.

         Section  10.  INSPECTORS.  The Board may,  in advance of any meeting of
shareholders,  appoint  one or more  inspectors  to act at such  meeting  or any
adjournment  thereof.  If the inspectors  shall not be so appointed or if any of
them shall fail to appear or act,  the  chairman of the meeting  may, and on the
request of any shareholder  entitled to vote thereat shall,  appoint inspectors.
Each inspector, before entering upon the discharge of his duties, shall take and
sign an oath  faithfully to execute the duties of inspector at such meeting with
strict  impartiality  and according to the best of his ability.  The  inspectors
shall  determine the number of shares  outstanding and the voting power of each,
the number of shares represented at the meeting,  the existence of a quorum, the
validity and effect of proxies,  and shall receive  votes,  ballots or consents,
hear and determine all challenges and questions  arising in connection  with the
right to vote, count and tabulate all votes, ballots or consents,  determine the
result,  and do such acts as are proper to  conduct  the  election  or vote with
fairness to all  shareholders.  On request of the chairman of the meeting or any
shareholder  entitled to vote  thereat,  the  inspectors  shall make a report in
writing of any challenge, request or matter determined by them and shall execute
a certificate of any fact found by them. No director or candidate for the office
of



director shall act as inspector or an election of directors. Inspectors need not
be shareholders.

         Section 11. CONSENT OF SHAREHOLDERS  IN LIEU OF MEETING.  To the extent
permitted by law, the meeting and vote of shareholders  can be dispensed with if
all of the  shareholders who would have been entitled to vote upon the action if
such meeting were held shall consent in writing to such  corporate  action being
taken.

                                   ARTICLE II

         Section 1. GENERAL POWERS.  The business and affairs of the Corporation
shall be managed by the Board.  The Board may  exercise all such  authority  and
powers of the  Corporation  and do all such lawful acts and things as are not by
statute or the Certificate of Incorporation directed or required to be exercised
or done by the shareholders.

         Section 2. ELECTION AND TERMS. The directors,  other than those who may
be elected by the  holders of any class or series of stock  having a  preference
over another class or series of stock as to dividends or upon liquidation, shall
be  classified,  with respect to the time for which they  severally hold office,
into three classes, as nearly equal in number as possible,  as determined by the
Board,  one class to be  originally  elected  for a term  expiring at the annual
meeting  of  shareholders  to be held in 1989,  another  class to be  originally
elected for a term expiring at the annual meeting of  shareholders to be held in
1990,  and another  class to be  originally  elected for a term  expiring at the
annual  meeting  of  shareholders  to be held in 1991,  with each  class to hold
office until its successor is elected and  qualified.  At each annual meeting of
the  shareholders of the  Corporation,  the successors of the class of directors
whose term  expires at the  meeting  shall be elected to hold  office for a term
expiring at the annual meeting of shareholders  held in the third year following
the year of their election.

         Section 3. PLACE OF MEETINGS. Meetings of the Board may be held at such
place, within or without the State of incorporation,  as the Board may from time
to time  determine or as shall be specified in the notice or waiver of notice of
such meeting.

         Section 4.  ANNUAL  MEETING.  The Board  shall meet for the  purpose of
organization, the election of officers and the transaction of other business, as
soon as practicable after each annual meeting of the  shareholders,  on the same
day and at the same place where such  annual  meeting  shall be held.  Notice of
such  meeting  need not be given.  Such meeting may be held at any other time or
place (within or without the State of incorporation) which shall be specified in
a notice thereof given as hereinafter provided in Section 7 of this Article II.

         Section 5.  REGULAR  MEETINGS.  Regular  meetings of the Board shall be
held at such time and place as the Board may from time to time determine. If any
day fixed for a regular  meeting shall be a legal holiday at the place where the
meeting is to be held,  then the meeting  which would  otherwise be held on that
day shall be held at the same hour on



the next succeeding  business day. Notice of regular  meetings of the Board need
not be given except as otherwise required by statute or these By-Laws.

         Section  6.  SPECIAL  MEETINGS.  Special  meetings  of the Board may be
called by two or more  directors  of the  Corporation  or by the Chairman of the
Board,  the Vice  Chairman of the Board,  the Lead  Independent  Director or the
President.

         Section 7. NOTICE OF MEETINGS.  Notice of each  special  meeting of the
Board (and of each regular  meeting for which notice shall be required) shall be
given by the  Secretary  as  hereinafter  provided  in this  Section 7, in which
notice  shall be  stated  the time and place  (within  or  without  the State of
incorporation) of the meeting. Notice of each such meeting shall be delivered to
each director either personally or by telephone,  telegraph,  cable or wireless,
at least  twenty-four  hours before the time at which such meeting is to be held
or by first-class mail, postage prepaid,  addressed to him at his residence,  or
usual  place of  business,  at least  three  days  before  the day on which such
meeting  is to be  held.  Notice  of any such  meeting  need not be given to any
director who shall,  either before or after the meeting,  submit a signed waiver
of notice or who shall attend such meeting  without  protesting,  prior to or at
its  commencement,  the lack of notice to him. Except as otherwise  specifically
required  by these  By-Laws,  a notice or waiver  of  notice of any  regular  or
special meeting need not state the purpose of such meeting.

         Section 8. QUORUM AND MANNER OF ACTING.  A majority of the entire Board
shall be present in person at any meeting of the Board in order to  constitute a
quorum for the transaction of business at such meeting, and, except as otherwise
expressly required by statute or the Certificate of Incorporation,  the act of a
majority  of the  directors  present at any meeting at which a quorum is present
shall be the act of the Board.  In the absence of a quorum at any meeting of the
Board,  a majority  of the  directors  present  thereat,  or if no  director  be
present,  the Secretary,  may adjourn such meeting to another time and place, or
such meeting, unless it be the annual meeting of the Board, need not be held. At
any  adjourned  meeting  at which a  quorum  is  present,  any  business  may be
transacted which might have been transacted at the meeting as originally called.
Except as provided in Article III of these By-Laws, the directors shall act only
as a Board and the individual directors shall have no power as such.

         Section  9.  ORGANIZATION.  The  Chairman  of the  Board  shall  act as
chairman of and preside at all meetings of the Board at which he is present.  If
the  Chairman of the Board  shall be absent  from any meeting of the Board,  the
duties otherwise provided in this Section 9 of Article II to be performed by him
at such meeting shall be performed at such meeting by the individual  elected by
the Board to act as Lead  Independent  Director.  If the  Chairman  of the Board
shall be  absent  from any  meeting  of the  Board,  and if no Lead  Independent
Director has been elected or if the Lead Independent  Director is not present at
the meeting, the Vice Chairman of the Board shall act as chairman of and preside
at such  meeting.  If the Chairman of the Board shall be absent from any meeting
of the Board, and if no Lead Independent  Director or Vice Chairman of the Board
has been elected or if the Lead  Independent  Director and the Vice  Chairman of
the Board are not present at the meeting, the President shall act as chairman of
and preside at such



meeting.  If the  Chairman  of the Board shall be absent from any meeting of the
Board,  and if no Lead  Independent  Director or Vice  Chairman of the Board has
been elected and no  President  has been  appointed  or if the Lead  Independent
Director,  the Vice  Chairman of the Board and the  President are not present at
the meeting,  another  director  chosen by a majority of the  directors  present
shall act as chairman of and preside at such meeting.  The Secretary (or, in his
absence or inability to act, any person  appointed by the chairman) shall act as
secretary of the meeting and keep the minutes thereof.

         Section 10. RESIGNATIONS. Any director of the Corporation may resign at
any time by giving written notice of his resignation to the Board or Chairman of
the Board or the President or the  Secretary.  Any such  resignation  shall take
effect at the time  specified  therein,  or,  if the time  when it shall  become
effective shall not be specified  therein,  immediately  upon its receipt;  and,
unless otherwise specified therein, the acceptance of such resignation shall not
be necessary to make it effective.

         Section  11.  NEWLY  CREATED  DIRECTORSHIPS  AND  VACANCIES.  Except as
otherwise provided for or fixed by or pursuant to the provisions of Article 4 of
the  Certificate of  Incorporation  relating to the rights of the holders of any
class or series of stock  having a preference  over  another  class or series of
stock as to dividends or upon  liquidation to elect  directors  under  specified
circumstances,  newly created  directorships  resulting from any increase in the
number of  directors  and any  vacancies  on the  Board  resulting  from  death,
resignation,  disqualification,  removal or other  cause  shall be filled by the
affirmative vote of a majority of the remaining  directors then in office,  even
though less than a quorum of the Board.  Any director elected in accordance with
the preceding  sentence  shall hold office for the remainder of the full term of
the class of directors in which the new  directorship was created or the vacancy
occurred  and until  such  director's  successor  shall  have been  elected  and
qualified.  No decrease in the number of directors  constituting the Board shall
shorten the term of any incumbent director.

         Section 12. REMOVAL OF DIRECTORS. Subject to the rights of any class or
series of stock having a preference  over another class or series of stock as to
dividends or upon liquidation to elect directors under specified  circumstances,
any  director  may be  removed  from  office,  only  with  cause and only by the
affirmative  vote of (i) the holders of 80% of the combined  voting power of the
then  outstanding  shares of stock entitled to vote generally in the election of
directors,  voting together as a single class and (ii) a majority of such shares
beneficially owned by the persons not affiliated with an Interested  Shareholder
(as defined in Article 14 of the Certificate of Incorporation).

         Section 13.  COMPENSATION.  The Board shall have  authority  to fix the
compensation,  including fees and  reimbursement  of expenses,  of directors for
services to the  Corporation  in any  capacity,  provided no such payment  shall
preclude any director  from serving the  Corporation  in any other  capacity and
receiving compensation therefore.

         Section  14.  ACTION BY THE  BOARD.  Any  member of the Board or of any
Committee thereof may participate in a meeting of the Board or such committee by
means of a conference telephone or similar communications equipment allowing all
persons  participating  in the  meeting  to hear each of them at the same  time.
Participation



by such means shall  constitute  presence in person at a meeting.  To the extent
permitted under the laws of the State of  incorporation,  any action required or
permitted  to be taken at any meeting of the Board or of any  committee  thereof
may be taken without a meeting if all members of the Board or committee,  as the
case may be, consent  thereto in writing,  and the writing or writings are filed
with the minutes of proceedings of the Board or committee.

         Section 15. SHAREHOLDER NOMINATION OF DIRECTOR CANDIDATES. NOTIFICATION
OF NOMINATION.  Subject to the rights of holders of any class or series of stock
having a  preference  over  another  class or series of stock as to dividends or
upon  liquidation to elect additional  directors under specified  circumstances,
nominations  for the election of  directors  may be made by the Board or a proxy
committee  appointed by the Board or by any shareholder  entitled to vote in the
election of directors  generally.  However,  any shareholder entitled to vote in
the  election  of  directors  generally  may  nominate  one or more  persons for
election as directors at a meeting only if written notice of such  shareholder's
intent to make such nomination or nominations has been given, either by personal
delivery or by United  States mail,  postage  prepaid,  to the  Secretary of the
Corporation  not later  than (i) with  respect to an  election  to be held at an
annual  meeting of  shareholders,  60 days in advance of such meeting,  and (ii)
with respect to an election to be held at a special meeting of shareholders  for
the election of  directors,  the close of business on the seventh day  following
the date on which  notice of such meeting is first given to  shareholders.  Each
such notice  shall set forth:  (a) the name and address of the  shareholder  who
intends to make the nomination and the person or persons to be nominated;  (b) a
representation  that the  shareholder  is a  holder  of  record  of stock of the
Corporation  entitled to vote at such meeting and intends to appear in person or
by proxy at the  meeting to  nominate  the person or  persons  specified  in the
notice;  (c) a description of all  arrangements  or  understandings  between the
shareholder and each nominee and any other person or persons (naming such person
or persons)  pursuant to which the nomination or  nominations  are to be made by
the shareholder;  (d) such other information  regarding each nominee proposed by
such  shareholder as would be required to be included in a proxy statement filed
pursuant to the proxy rules of the Securities and Exchange  Commission,  had the
nominee been nominated,  or intended to be nominated,  by the Board; and (e) the
consent of each nominee to serve as a director of the Corporation if so elected.
The  chairman of the meeting may refuse to  acknowledge  the  nomination  of any
person not made in compliance with the foregoing procedure.

         Section 16. THE LEAD INDEPENDENT  DIRECTOR.  The Board may from time to
time elect a director to serve as Lead Independent  Director,  which shall be an
"independent  director" in accordance with the Securities  Exchange Act of 1934,
as amended, and the rules promulgated thereunder and the applicable rules of the
New York Stock  Exchange.  The Lead  Independent  Director,  if one be  elected,
shall,  if  present,  preside  at each  meeting  of the Board in the case of the
absence or  inability  to act of the  Chairman of the Board,  and when so acting
shall have all the powers of, and be subject to all the  restrictions  upon, the
Chairman of the Board,  and shall  coordinate the activities of the  independent
directors and have such other authority and powers as the Board may from time to
time prescribe.



         Section  17.  TERM  LIMITS.  Notwithstanding  anything  herein  to  the
contrary,  the total  cumulative  length of time that any Outside  Director  may
serve on the Board  shall be  limited to a maximum  of three  three-year  terms,
whether  consecutively  or in total,  plus any portion of an earlier  three-year
term that such Outside  Director may have been  appointed to serve.  An "Outside
Director" shall mean a member of the  Corporation's  Board who is not an officer
or employee of the Corporation.

         Section 1. EXECUTIVE AND OTHER COMMITTEES. The Board may, by resolution
passed by a majority of the whole Board, designate one or more committees,  each
committee  to consist of two or more of the  directors of the  Corporation.  The
Board may designate one or more directors as alternate members of any committee,
who may  replace  any  absent  or  disqualified  member  at any  meeting  of the
committee.  Any such committee,  to the extent provided in the resolution  shall
have and may exercise the powers of the Board in the  management of the business
and affairs of the Corporation, and may authorize the seal of the Corporation to
be affixed to all papers which may require it;  provided,  however,  that in the
absence or  disqualification  of any member of any such committee or committees,
the member or members thereof present at any meeting and not  disqualified  from
voting,  whether or not he or they constitute a quorum, may unanimously  appoint
another  member  of the  Board to act at the  meeting  in the  place of any such
absent  or  disqualified  member.  Each  committee  shall  keep  minutes  of its
proceedings  and shall report such minutes to the Board when required.  All such
proceedings  shall be subject to revision or alteration by the Board;  provided,
however,  that  third  parties  shall  not be  prejudiced  by such  revision  or
alteration.

         Section 2.  GENERAL.  A majority of any  committee  may  determine  its
action  and fix the time and  place of its  meetings,  unless  the  Board  shall
otherwise provide.  Notice of such meetings shall be given to each member of the
committee in the manner  provided for in Article II,  Section 7. The Board shall
have the power at any time to fill vacancies in, to change the membership of, or
to dissolve any such  committee.  Nothing  herein shall be deemed to prevent the
Board from appointing one or more  committees  consisting in whole or in part of
persons who are not directors of the  Corporation;  provided,  however,  that no
such committee shall have or may exercise any authority of the Board.

                                   ARTICLE IV

unless otherwise specified therein, the acceptance of such resignation shall not
be necessary to make it effective.

         Section 3.  REMOVAL.  Any  officer or agent of the  Corporation  may be
removed,  either with or without cause, at any time, by the vote of the majority
of the entire  Board at any meeting of the Board,  or,  except in the case of an
officer or agent elected or appointed by the Board, by the Chairman of the Board
or the  President.  Such removal shall be without  prejudice to the  contractual
rights, if any, of the person so removed.

         Section 4.  VACANCIES.  A vacancy in any office,  whether  arising from
death, resignation,  removal or any other cause, may be filled for the unexpired

corporation,  any  of  whose  stock  or  other  securities  may be  held  by the
Corporation, at meetings of the holders of the stock or other securities of such
other corporation,  or to consent in writing,  in the name of the Corporation as
such  holder,  to any action by such other  corporation,  and may  instruct  the
person or persons so  appointed as to the manner of casting such votes or giving
such consent,  and may execute or cause to be executed in the name and on behalf
of the Corporation and under its corporate seal, or otherwise,  all such written
proxies or other instruments as he may deem necessary or proper in the premises.

         Section 1. STOCK  CERTIFICATES.  Each  holder of shares of stock of the
Corporation  shall be entitled to have a  certificate,  in such form as shall be
approved by



the Board,  certifying the number of shares of the Corporation owned by him. The

Corporation  by the Chairman of the Board or the  President or a  Vice-President
and by the Secretary or an Assistant  Secretary or the Treasurer or an Assistant
Treasurer  and  sealed  with the seal of the  Corporation  (which  seal may be a
facsimile,  engraved  or  printed);  provided,  however,  that  where  any  such
certificate is  countersigned  by a transfer agent other than the Corporation or
its employee,  or is registered by a registrar other than the Corporation or one
if its  employees,  the signature of the officers of the  Corporation  upon such
certificates  may be  facsimiles,  engraved or printed.  In case any officer who
shall  have  signed  or whose  facsimile  signature  has been  placed  upon such
certificates shall have ceased to be such officer before such certificates shall
be issued,  they may  nevertheless  be issued by the  Corporation  with the same
effect as if such officer were still in office at the date of their issue.

         Section 2. BOOKS OF ACCOUNT AND RECORD OF  SHAREHOLDERS.  The books and
records of the  Corporation  may be kept at such  places  within or without  the
State  of  incorporation  as the  Board  of  Directors  may  from  time  to time
determine. The stock record books and the blank stock certificate books shall be
kept by the Secretary or by any other  officer or agent  designated by the Board
of Directors.

         Section  3.  TRANSFER  OF SHARES.  Transfers  of shares of stock of the
Corporation  shall be made on the stock  records  of the  Corporation  only upon
authorization  by the registered  holder thereof,  or by his attorney  thereunto
authorized  by power of attorney  duly  executed and filed with the Secretary or
with a transfer clerk,  and on surrender of the certificate or certificates  for
such shares  properly  endorsed or accompanied by a duly executed stock transfer
power and the payment of all taxes thereon. Except as otherwise provided by law,
the  Corporation  shall be entitled to recognize the exclusive right of a person
in whose  name any share or shares  stand on the record of  shareholders  as the
owner of such share or shares for all purposes,  including,  without limitation,
the  rights to receive  dividends  or other  distributions,  and to vote as such
owner,  and the Corporation  may hold any such  shareholder of record liable for
calls and assessments  and the  Corporation  shall not be bound to recognize any
equitable or legal claim to or interesting  any such share or shares on the part
of any  other  person  whether  or not it shall  have  express  or other  notice
thereof.  Whenever any transfers of shares shall be made for collateral security
and  not  absolutely,  and  both  the  transferor  and  transferee  request  the
Corporation to do so, such fact shall be stated in the entry of the transfer.

         Section 4.  REGULATIONS.  The Board may make such additional  rules and
regulations,  not  inconsistent  with these  By-Laws,  as it may deem  expedient
concerning the issue,  transfer and  registration of certificates  for shares of
stock of the Corporation.  It may appoint,  or authorize any officer or officers
to appoint,  one or more transfer  agents or one or more transfer clerks and one
or more registrars and may require all  certificates for shares of stock to bear
the signature or signatures of any of them.

         Section 5. LOST, DESTROYED OR MUTILATED CERTIFICATES. The holder of any
certificate   representing  the  shares  of  stock  of  the  Corporation   shall
immediately  notify the  Corporation  of any loss,  destruction or mutilation of
such  certificate,  and the  Corporation



may issue a new certificate of stock in the place of any certificate theretofore
issued by it which the owner thereof shall allege to have been lost,  stolen, or
destroyed  or which  shall  have  been  mutilated,  and the  Board  may,  in its
discretion,  require  such  owner or his  legal  representatives  to give to the
Corporation a bond in such sum, limited or unlimited,  and in such form and with
such surety or sureties as the Board in its absolute discretion shall determine,
to indemnify  the  Corporation  against any claim that may be made against it on
account of the alleged loss, theft, or destruction of any such  certificate,  or
the   issuance  of  a  new   certificate.   Anything   herein  to  the  contrary
notwithstanding,  the Board, in its absolute discretion, may refuse to issue any
such new certificate, except pursuant to legal proceedings under the laws of the
State of incorporation.

         Section 6. FIXING OF RECORD  DATE.  In order that the  Corporation  may
determine the shareholders  entitled to notice of, or to vote at, any meeting of
shareholders  or any  adjournment  thereof,  or to express  consent to corporate
action in  writing  without a meeting,  or  entitled  to receive  payment of any
dividend  or other  distribution  or  allotment  of any  rights,  or entitled to
exercise any rights in respect of any change, conversion or exchange of stock or
for the purpose of any other  lawful  action,  the Board may fix, in advance,  a
record  date,  which  shall not be more than sixty nor less than ten days before
the date of such meeting,  nor more than sixty days prior to any other action. A
determination  of shareholders of record entitled to notice of, or to vote at, a
meeting of shareholders shall apply to any adjournment of the meeting; provided,

time be fixed by the Board.

offices other than said principal or registered  office, at such place or places
either within or without the State of incorporation.
