                         OF THE GENERAL CORPORATION LAW
                            OF THE STATE OF DELAWARE



                  SILGAN  HOLDINGS  INC., a Delaware  corporation,  the original
Certificate of  Incorporation  of which was filed with the Secretary of State of
the State of  Delaware on April 6, 1989,  HEREBY  CERTIFIES  that this  Restated
Certificate  of   Incorporation,   restating,   integrating   and  amending  its
Certificate  of  Incorporation,  was duly proposed by its Board of Directors and
adopted by its  stockholders  in  accordance  with  Sections  242 and 245 of the
General  Corporation  Law of the State of Delaware,  and that the capital of the
Corporation  is not being  reduced  under or by reason of any  amendment in this
Restated Certificate of Incorporation.

                  FIRST:  The name of this corporation  (the  "Corporation")  is
SILGAN HOLDINGS INC.

                  SECOND:   The  address  of  the   registered   office  of  the
Corporation  in the State of Delaware is Corporation  Trust Center,  1209 Orange
Street,  in the  City of  Wilmington,  County  of New  Castle.  The  name of its
registered agent at such address is The Corporation Trust Company.

                  THIRD:  The  purpose  of the  Corporation  is to engage in any
lawful  act or  activity  for which a  corporation  may be  organized  under the
General  Corporation Law of the State of Delaware (the "GCL"),  and, in general,
to possess and exercise all the powers and  privileges  granted by the GCL or by
any other law or by this Restated Certificate of Incorporation, together







with any powers  incidental  thereto,  so far as such powers and  privileges are
necessary or convenient to the conduct,  promotion or attainment of the business
or purposes of the Corporation.

                  FOURTH:   A.  The  number  of  directors  of  the  Corporation
constituting  the entire Board of Directors shall be six. The Board of Directors
shall be divided into three equal classes,  with the term of office of the first
class  (the  "Class I  Directors")  to  expire  at the 1998  annual  meeting  of
stockholders,  the term of office of the second class (the "Class II Directors")
to expire at the 1999 annual meeting of  stockholders  and the term of office of
the third class (the "Class III Directors") to expire at the 2000 annual meeting
of stockholders.  After the filing of this Restated Certificate of Incorporation
with the Secretary of State of the State of Delaware,  the  stockholders  of the
Corporation  shall elect the Board of Directors of the  Corporation  at the 1997
annual meeting of stockholders or by the consent in writing, in lieu of the 1997
annual  meeting of  stockholders,  of the  holders of  outstanding  stock of the
Corporation  having  not less than the  minimum  number of votes  that  would be
necessary  to  authorize  or take such  action at a meeting  at which all shares
entitled to vote thereon were present and voted.  Any  vacancies in the Board of
Directors for any reason,  and any directorships  resulting from any increase in
the number of directors,  may be filled only by the Board of Directors  (and not
by the stockholders),  acting by a majority of the directors then in office, and
any  directors so chosen shall hold office until the next  election of the class
for which such directors shall have been chosen and until their successors shall
be elected and qualified. Notwithstanding the foregoing, and except as otherwise
required by law, whenever the holders of any one or


                                       -2-





more  series of  Preferred  Stock (as defined in Article  SIXTH)  shall have the
right,  voting  separately  as a class,  to elect one or more  directors  of the
Corporation,  the terms of the  director or  directors  elected by such  holders
shall expire at the next succeeding  annual meeting of stockholders.  Subject to
the  foregoing,  at each annual  meeting of  stockholders  the successors to the
class of directors  whose term shall then expire shall be elected to hold office
for a term expiring at the third succeeding annual meeting.

                  B. At all  meetings of the Board of  Directors,  a majority of
the Directors then in office shall be required to constitute a quorum ("Quorum")
for the transaction of business.  The approval of a majority of the entire Board
of Directors,  at a meeting at which a Quorum is present and acting  throughout,
shall be required to approve all matters  submitted  to the Board of  Directors;
provided,  however,  that the  approval  of a  majority  of the  members  of any
committee  of the Board of  Directors  shall be  required to approve all matters
submitted to such committee.

                  C. Notwithstanding any other provisions of this Certificate of
Incorporation  or the By-Laws of the Corporation (and  notwithstanding  the fact
that some  lesser  percentage  may be  specified  by law,  this  Certificate  of
Incorporation  or the ByLaws of the  Corporation),  any  director  or the entire
Board of Directors of the  Corporation  may be removed at any time, but only for
cause  and only by the  affirmative  vote of the  holders  of 75% or more of the
outstanding  shares  of  capital  stock  of the  Corporation  entitled  to  vote
generally  in the  election of  directors  (considered  for this  purpose as one
class)  cast  at  a  meeting  of  the  stockholders  called  for  that  purpose.
Notwithstanding the foregoing, and except as otherwise required


                                       -3-





by law,  whenever the holders of any one or more series of Preferred Stock shall
have the right,  voting separately as a class, to elect one or more directors of
the  Corporation,  the  provisions  of Section C of this Article shall not apply
with respect to the  director or directors  elected by such holders of Preferred
Stock.

                  D. There shall be an Audit Committee consisting of two or more
of the directors of the  Corporation,  who shall perform such functions as shall
be established by the Board of Directors.

                  FIFTH:  The business and affairs of the  Corporation  shall be
managed by or under the direction of the Board of  Directors,  provided that the
Corporation  may retain such  qualified  persons (as  determined by the Board of
Directors) to provide the Corporation with general  management,  supervision and
administrative services relating to the operations of the Corporation.

                  Except as  specifically  authorized by the Board of Directors,

venture, firm, limited liability company, association, trust or other enterprise

change or  repeal  any  provision  contained  in this  Restated  Certificate  of
Incorporation  in the manner now or hereafter  prescribed by law,  provided that

adopted by the Board of  Directors by approval of a majority of the entire Board
of  Directors,  at a meeting at which a Quorum is present and acting  throughout
and (ii) the proposed amendment,  alteration,  change or repeal be approved by a

or  intestate,  made,  or  threatened to be made, a defendant or involved in any
manner  in  any  action,   suit  or   proceeding   (whether   civil,   criminal,
administrative, investigative or otherwise) by reason of the fact that he, is or
was a director,  officer,  employee or agent of the  Corporation or by reason of
the fact that such director,  officer,  employee or agent, at the request of the

payment of any amounts to any person  pursuant to this  Article  ELEVENTH  shall
subrogate  the  Corporation  to any right such person may have against any other

entitled to by law. No amendment or repeal of this paragraph A of Article


                                      -11-

intentional  misconduct or a knowing violation of law, (iii) pursuant to Section
174 of the GCL, or (iv) for any transaction  from which such director derived an
improper  personal  benefit.  No amendment  to or repeal of this  paragraph B of
Article  ELEVENTH  shall apply to or have any effect on the liability or alleged
liability of any director of the  Corporation for or with respect to any acts or
omissions of such director occurring prior to such amendment or repeal.

                  C.  In  furtherance  and  not  in  limitation  of  the  powers
conferred by statute:

                      (i) the Corporation may purchase and maintain insurance on
behalf of any person who is or was a director, officer, employee or agent of the
Corporation,  or is serving at the  request of the  Corporation  as a  director,
officer, employee or agent of another corporation,  partnership,  joint venture,
trust,  employee benefit plan or other enterprise against any liability asserted
against  him and  incurred  by him in any such  capacity,  or arising out of his
status as such, whether or not the Corporation would have the power to indemnify
him against such liability under the provisions of law; and


                                      -12-

permitted by law and including as part thereof provisions with respect to any or
all of the  foregoing  to ensure  the  payment  of such  amounts  as may  become

without the State of Delaware,  as the By-Laws of the  Corporation  may provide.
The books of the Corporation may be kept (subject to any provision  contained in
the GCL)  outside  the  State of  Delaware  at such  place or  places  as may be
designated  from time to time by the Board of Directors or in the By-Laws of the
Corporation.
