      Section 6. Organization of Meetings. Meetings of the shareholders shall be
presided  over by the  Chairman  of the Board,  if there be one, or if he is not
present,  the President,  or if he is not present, by a chairman to be chosen at

Secretary, shall act as Secretary of the meeting, if present.

      Section 7. Voting.  At each meeting of  shareholders,  except as otherwise
provided by statute or the Certificate of Incorporation,  every holder of record
of stock  entitled  to vote shall be  entitled to one vote in person or by proxy
for  each  share  of such  stock  standing  in his  name on the  records  of the
Corporation.  Elections of directors  shall be  determined by a plurality of the
votes  cast  there  at  and,  except  as  otherwise  provided  by  statute,  the
Certificate  of  Incorporation,  or these  By-Laws,  all other  action  shall be
determined by a majority of the votes cast at such  meeting.  Each proxy to vote
shall be either in writing and signed, or given by telegram,  radio,  radiogram,
cable or equivalent  electronic  communication made by the shareholder or by his
duly authorized agent.

      At all elections of directors, the voting shall be in such other manner as
may be  determined by the Board of  Directors,  unless a shareholder  present in
person or by proxy  entitled  to vote at such  election,  and  before the voting
begins,  demands election by ballot.  With respect to any other matter presented
to the  shareholders  for their  consideration  at a  meeting,  any  shareholder
entitled to vote may, on any question, demand a vote by ballot.

      A complete list of the shareholders entitled to vote at each such meeting,
arranged  in  alphabetical  order  (within  each  class,   series  or  group  of
shareholders  maintained by the  Corporation  for convenience of reference) with
the  address of each,  and the number of shares  registered  in the name of each
shareholder,  shall be  prepared by the  Secretary  and shall be produced at the
time and place during the meeting and shall be subject to the  inspection of any
shareholder for reasonable periods during the meeting.

      Section 8.  Inspectors  of Election.  The Board of Directors in advance of
any  meeting  of  shareholders,   or  the  tabulation  of  written  consents  of
shareholders  without a meeting,  may appoint one or more Inspectors of Election
to act at the meeting or any  adjournment  thereof or to tabulate such consents.
If Inspectors of Election are not so appointed, the chairman of the meeting may,
and on the request of any shareholder  entitled to vote,  shall,  appoint one or
more  Inspectors  of  Election.  In case any person  appointed  as  Inspector of
Election fails to appear or act, the vacancy may be filled by  appointment  made
by the Board of  Directors  in advance of the  meeting or at the  meeting by the
chairman of the meeting.  Each Inspector of Election,  before  entering upon the
discharge of his duties,  shall take and sign an oath to faithfully  execute the
duties of Inspector of Election at such  meeting  with strict  impartiality  and
according to the best of his ability. If appointed, Inspectors of Election shall
take  charge  of the  polls  as may be  required  by law  and,  when the vote is
completed, shall make a report of the result of the vote taken and of such other
facts as may be required by law.

      Section 9. Action by Consent. Any action required or permitted to be taken
at any meeting of shareholders may be taken without a meeting, if, prior to such
action, a written consent or consents thereto,  setting forth such action, is or
are  signed  by the  holders  of  record  of all of the  shares  of stock of the
Corporation or, in the  alternative,  by the holders of record of so many of the
shares of the stock of the  Corporation as are required by law for the taking of
such action by written  consent,  if, either the  Corporation  solicits for such
consents or proxies for consents  from the holders of all of the shares of stock
of the  Corporation,  issued,  outstanding  and  entitled  to vote  thereon  and
promptly  notifies all  non-consenting  holders of stock of the  Corporation  as
required by law. Any such solicitation or notice to non-consenting  shareholders
hereunder  shall specify at least the action to which the consent  relates,  its
proposed  effective date, any conditions  precedent to such action,  the date of
tabulation of consents,  and the rights of all  shareholders who are entitled to
dissent from such action,  if any,  together  with the  requisite  procedure for
assertion  and   enforcement  of  those  rights.   In  the  case  of  a  merger,
consolidation,  or sale,  lease,  exchange or other disposition of substantially
all of the assets of the  Corporation,  any  required or  permitted  shareholder
action may be taken by a prior  written  consent  or  consents  to such  action,
setting forth the action to be taken, signed by the holders of all of the shares
of every  class of issued  and  outstanding  stock of the  Corporation,  issued,
outstanding  and entitled to vote,  with the same notice to all other holders of
stock of the Corporation as is required  hereunder to be sent to  non-consenting
shareholders.

Directors  of the  Corporation  shall  consist  of at least  five and up to nine

of directors may be determined by a resolution passed by a majority of the whole
Board or by a vote of the holders of record of at least a majority of the shares
of stock of the Corporation, issued and outstanding and entitled to vote.

      A majority of the members of the Board of Directors  then  holding  office
shall constitute a quorum,  which in no case shall be less than one-third of the
total  number of  directors  or less than two  directors,  except  that when the
entire Board  consists of one  Director,  then one Director  shall  constitute a
quorum for the transaction of business, but if at any meeting of the Board there
may shall be less than a quorum present, a majority of those present may adjourn
the meeting from time to time until a quorum shall have been obtained.

      Directors shall hold office until the next annual election and until their
successors  shall have been  elected  and shall have  qualified,  unless  sooner
displaced.

      Whenever any vacancy  shall have  occurred in the Board of  Directors,  by
reason of death, resignation, increase in the number of directors, or otherwise,
other  than  removal  of a  director  with  or  without  cause  by a vote of the
shareholders, or is scheduled to occur pursuant to a resignation tendered to the
Board  effective  at a future  date,  it shall be  filled by a  majority  of the
directors  then holding  office  though less than a quorum  (except as otherwise
provided  by law) from a nominee or  nominees  selected  by the  Nominating  and
Corporate  Governance  Committee,3  or in the case of a  subsequently  effective
resignation,  by such a majority of the directors including the resignee,  or by
the  shareholders,  from a nominee or nominees  selected by the  Nominating  and
Corporate  Governance  Committee,4  and the person so chosen  shall hold  office
until the next annual  election and until his  successor is duly elected and has
qualified.

each other.  Notice of an adjourned  meeting need not be given if time and place

resolution  passed by a majority of the whole  Board,  designate  from among its
members one or more committees which shall consist of one or more directors. The

                                 INDEMNIFICATION

      Section 1. Actions by Others.  The  Corporation  (1) shall  indemnify  any
person  who  was or is a  party  or is  threatened  to be  made a  party  to any
threatened,  pending or completed  action,  suit or  proceeding,  whether civil,
criminal,  administrative  or  investigative  (other than an action by or in the
right of the  Corporation)  by reason of the fact that he is or was a  director,
officer or trustee of the Corporation or of any constituent corporation absorbed
by the  Corporation  in a  consolidation  or merger and (2) except as  otherwise
required by Section 3 of this Article,  may indemnify any person who was or is a
party  or is  threatened  to be  made a  party  to any  threatened,  pending  or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative  (other than an action by or in the right of the  Corporation)  by
reason  of the fact  that he (a) is or was an  employee  or  agent or the  legal
representative  of a  director,  officer,  trustee,  employee  or  agent  of the
Corporation or of any absorbed constituent corporation, or (b) is or was serving
at the request of the Corporation or of any absorbed constituent  corporation as
a director,  officer,  employee, agent of or participant in another corporation,
partnership,   joint  venture,   trust  or  other   enterprise,   or  the  legal
representative  of  such  a  person  against  expenses,   costs,   disbursements
(including  attorneys'  fees),   judgments,   fines  and  amounts  actually  and
reasonably  incurred by him in good faith and in  connection  with such  action,
suit or proceeding  if he acted in a manner he  reasonably  believed to be in or
not opposed to the best  interests of the  Corporation,  and with respect to any
criminal  action or proceeding,  he had no reasonable  cause to believe that his
conduct was  unlawful.  The  termination  of any action,  suit or  proceeding by
judgment,  order, settlement,  conviction,  or upon a plea of nolo contendere or
its equivalent,  shall not, of itself,  create a presumption that the person did
not meet the applicable standard of conduct.


                                      -7-



      Section 2. Actions by or in the Right of the Corporation.  The Corporation
shall  indemnify  any person who was or is a party or is threatened to be made a
party to any threatened,  pending or completed action or suit by or in the right
of the Corporation to procure a judgment in its favor by reason of the fact that
he is or was a director,  officer, trustee, employee or agent of the Corporation
or of any constituent  corporation  absorbed by the Corporation by consolidation
or merger, or the legal  representative of any such person, or is or was serving
at the request of the Corporation or of any absorbed constituent corporation, as
a director,  officer, trustee,  employee, agent of or participant,  or the legal
representative  of any such person in another  corporation,  partnership,  joint
venture,  trust or other enterprise against expenses (including attorneys' fees)
actually  and  reasonably  incurred  by him in  connection  with the  defense or
settlement  of such  action or suit if he acted in good faith and in a manner he
reasonably  believed  to be in or not  opposed  to  the  best  interests  of the
Corporation and except that no  indemnification  shall be made in respect of any
claim,  issue or matter as to which such person  shall have been  adjudged to be
liable to the  Corporation  unless  and only to the  extent  that the New Jersey
Superior  Court or the  court in which  such  action or suit was  brought  shall
determine upon  application  that,  despite the adjudication of liability but in
view of all the  circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses  which the New Jersey  Superior Court or
such other court shall deem proper.

      Section 3. Successful Defense. To the extent that a person who is or was a
director,  officer,  trustee,  employee  or agent of the  Corporation  or of any
constituent  corporation absorbed by the Corporation by consolidation or merger,
or the legal  representative  of any such  person,  has been  successful  on the
merits or otherwise in defense of any action,  suit or proceeding referred to in
Section 1 or Section 2 of this Article,  or in defense of any claim,  issue,  or
matter therein, he shall be indemnified  against expenses (including  attorneys'
fees) actually and reasonably incurred by him in connection therewith.

      Section 4. Specific Authorization.  Any indemnification under Section 1 or
Section  2 of this  Article  (unless  ordered  by a court)  shall be made by the
Corporation  only as authorized in the specific case upon a  determination  that
indemnification of the director, officer, trustee, employee, agent, or the legal
representative  thereof,  is proper in the circumstances  because he has met the
applicable  standard  of  conduct  set  forth  in said  Sections  1 and 2.  Such
determination  shall be made (1) by the Board of Directors by a majority vote of
quorum  consisting  of directors  who were not parties to such  action,  suit or
proceeding, or (2) if such a quorum is not obtainable, a quorum of disinterested
directors so directs, by independent legal counsel for a written opinion, (3) by
the shareholders.

      Section 5.  Advance of Expenses.  Expenses  incurred by any person who may
have a right  of  indemnification  under  this  Article  in  defending  civil or
criminal action, suit or proceeding may be paid by the Corporation in advance of
the final  distribution of such action,  suit or proceeding as authorized by the
Board of  Directors  upon  receipt  of an  undertaking  by or on  behalf  of the
director,  officer,  trustee,  employee, or the legal representative thereof, to
repay such amount unless it shall  ultimately be determined  that he is entitled
to be indemnified by the Corporation pursuant to this Article.


                                      -8-



      Section 6. Right of  Indemnity  not  Exclusive.  The  indemnification  and
advancement  of expenses  provided by this  Article  shall not exclude any other
rights  to  which  those  seeking  indemnification  may be  entitled  under  the
certificate of incorporation of the Corporation or any By-Law,  agreement,  vote
of shareholders or otherwise;  provided that no indemnification shall be made to
or on  behalf  of a  director,  officer,  trustee,  employee,  agent,  or  legal
representative if a judgment or other final adjudication adverse to such persons
establishes that his acts or omissions (a) were in breach of his duty of loyalty
to the Corporation or its shareholders,  as defined by law, (b) were not in good
faith or involved a knowing  violation of law or (c) resulted in receipt by such
person of an improper personal benefit.

      Section 7. Insurance.  The Corporation may purchase and maintain insurance
on behalf of any person who is or was a director,  officer, trustee, employee or
agent of the  Corporation  or of any  constituent  corporation  absorbed  by the
Corporation  by  consolidation  or merger of the  legal  representative  of such
person or is or was serving at the request of the Corporation or of any absorbed
constituent corporation as a director, officer, trustee, employee or agent of or
participant in another corporation,  partnership,  joint venture, trust or other
enterprise, or the legal representative of any such person against any liability
asserted  against him and incurred by him in any such  capacity,  arising out of
his status as such or by reason of his being or having been such, whether or not
the  Corporation  would have the power to indemnify  him against such  liability
under the provisions of this Article,  the New Jersey Business  Corporation Act,
or otherwise.

      Section 8. Invalidity of any Provision of this Article.  The invalidity or

                                    ARTICLE V

                                  CAPITAL STOCK

      Section  l.  Certificates.   The  interest  of  each  shareholder  of  the
Corporation  shall be evidenced by certificates for shares of stock in such form
(including  punch  cards,  magnetically  coded  or  otherwise  treated  forms to
facilitate  machine or automatic  processing) as the Board of Directors may from
time to time prescribe.  Each certificate of stock shall in any event state upon
its face all matters  required by law. Each  certificate  of stock issued at any
time the  Corporation  is  authorized  to issue shares of more than one class of
stock shall set out on it the  designations,  relative  rights,  preferences and
limitations of each class and series then  authorized and the power of the Board
of Directors to divide any such shares and to change such designations, relative
rights,  preferences and limitations.  The certificates of stock shall be signed
by the Chairman of the Board,  if any, or by the  President or a Vice  President
and  sealed  with  the  seal of the  Corporation  or a  facsimile  thereof,  and
countersigned by the Secretary,  or the Treasurer, or an Assistant Secretary, or
an Assistant  Treasurer,  and registered in such manner, if any, as the Board of
Directors  may  by  resolution   prescribe.   Where  any  such   certificate  is
countersigned by a transfer agent other than the Corporation or its employee, or
registered  by a  registrar  other than the  Corporation  or its  employee,  the
signature of any such officer may be a facsimile signature.  In case any officer
or officers who have signed,  or whose facsimile  signature or signatures  shall
have been used on, any 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 shall have been delivered by
the Corporation, such certificate or certificates may nevertheless be adopted by
the  Corporation and be issued and delivered as though the person or persons who
signed  such  certificate  or  certificates  or  whose  facsimile  signature  or
signatures  shall have been used  thereon  had not ceased to be such  officer or
officers of the Corporation.

      Section  2.  Transfer.  The  shares of stock of the  Corporation  shall be
transferred  only upon the books of the  Corporation  by the  holder  thereof in
person or by his attorney,  upon surrender for  cancellation of certificates for
the same number of shares,  with an  assignment  and power of transfer  endorsed
thereon or attached thereto, duly executed,  with such proof of the authenticity
of the signature as the Corporation or its agents may reasonably require.

      Section 3. Record  Dates.  The Board of Directors  may fix, in advance,  a

any meeting of shareholders, or the date for the payment of any dividend, or the
date for the  distribution  or  allotment  of any  rights,  or the date when any
change,  conversion  or exchange of capital  stock  shall go into  effect,  as a
record date for the determination of the shareholders entitled to notice of, and
to vote at,  any such  meeting,  or  entitled  to  receive  payment  of any such
dividend, or to exercise the rights in respect of any such change, conversion or
exchange of capital stock,  and in such case only such  shareholders as shall be
shareholders of record on the date so fixed shall be entitled to such notice of,
and to vote,  at such meeting,  or to receive  payment of such  dividend,  or to
receive such  distribution or allotment or rights or to exercise such rights, as
the case may be,  notwithstanding  any transfer of any stock on the books of the
Corporation  after such record date fixed as aforesaid.  Such  determination  of
shareholders of record shall remain in effect for any adjournment thereof unless
the Board of Directors fixes a new record date.

      Section 4. Lost  Certificates.  In the event that any certificate of stock
is lost, stolen,  destroyed, or mutilated,  the Board of Directors may authorize
the issuance of a new  certificate  of the same enter and for the same number of
shares in lieu thereof. The Board may in its discretion,  before the issuance of
such new  certificate,  require  the owner of the  lost,  stolen,  destroyed  or
mutilated  certificate,  or the legal  representative  of the owner,  to make an
affidavit or affirmation setting forth such acts as to the loss,  destruction or
mutilation  as it deems  necessary,  and to give the  Corporation a bond in such
reasonable sum as it directs to indemnify the Corporation.

      Section 3.  Loans to  Directors,  Officers  and  Employees.  To the extent
permitted  by the  Sarbanes-Oxley  Act of 2002 and any other  applicable  law or
regulation,7  the  Board of  Directors  may  authorize  the  loaning  of  money,
guaranteeing of obligations or other assistance to any other officer or employee
of the  Corporation or of any  subsidiary  whenever in the judgment of the Board
such loan,  guarantee or  assistance  may  reasonably be expected to benefit the
Corporation,  provided, however, if such officer or employee is also a director,
such loan,  guarantee or assistance must be approved by a majority of the entire
Board.  Any such  loan,  guarantee  or  assistance  may be made with or  without
interest,  and may be  unsecured,  or secured in such  manner as the Board shall
approve.
