                               UNIPLAST U.S., INC.


         Uniplast U.S., Inc., a Delaware corporation (the "Corporation"), hereby
certifies as follows:

         FIRST: The Board of Directors of the Corporation duly adopted the
following resolutions:

         RESOLVED, that it is advisable to amend and restate Article Fourth of
         the Certificate of Incorporation of the Corporation to read, in its
         entirety, as follows:

         FOURTH:

                  Section 1. Authorized Capital Stock.

                  The Corporation is authorized to issue 1,000 shares of common
         stock, par value $.01 per share ("Common Stock"), and 1,000 shares of
         preferred stock, par value $.01 share ("Preferred Stock").

                  The rights, preferences, privileges and restrictions granted
         to and imposed upon the Common Stock and the Preferred Stock are set
         forth below in this Article Fourth.

                  Subject to the rights of the holders of the Preferred Stock,
         the holders of the Common Stock shall be entitled to dividends out of
         funds legally available therefor, when, as and if declared and paid to
         the holders of Common Stock and, upon liquidation, dissolution or
         winding up of the Corporation, to share ratably in the assets of the
         Corporation.

                  Section 2. Dividends.

                  (a) Right to Dividends. Preferential cumulative dividends
         shall accrue on the Preferred-Stock (but, except as provided herein,
         need not be paid) as provided herein, whether or not such dividends
         have been declared and whether or not there are profits, surplus or
         other funds of the Corporation legally or contractually available for
         the payment of dividends. Except as otherwise provided below, dividends
         on each share of Preferred Stock (computed on the basis of a 360 day
         year of twelve 30-day months) shall accrue on a daily basis at the rate
         of eight percent (8%) per annum of $13,500 (the "Preference Amount"),
         compounded quarterly as of the last day of June, September, December
         and March, of each
   4
         year commencing with the June 30, September 30, December 31 or March 31
         next succeeding the date of the issuance of the Preferred Stock.

                  (b) Dividend Priority. Unless full dividends on all Preferred
         Stock for all past dividend periods and the then current dividend
         period shall have been paid or declared and a sum sufficient for the
         payment thereof set apart, (A) no dividend whatsoever other than a
         dividend payable solely in Common Stock shall be paid or declared and
         no distribution shall be made, on any Common Stock and (B) no Common
         Stock shall be purchased, redeemed or acquired by the Corporation and
         no monies shall be paid, set aside or made available therefor.

                  Section 3. Liquidation Rights of Preferred Stock.

                  (a) Preference. In the event of any liquidation, dissolution
         or winding up of the Corporation, whether voluntary or involuntary, the
         holders of the Preferred Stock then outstanding shall be entitled to be
         paid an amount equal to the Liquidation Preference (as hereinafter
         defined) out of the assets of the Corporation available for
         distribution to its stockholders, whether such assets are capital,
         surplus, or earnings, before any payment or declaration and setting
         apart for payment of any amount shall be made in respect of the Common
         Stock. The "Liquidation Preference" per share of the Preferred Stock
         shall be the Preference Amount plus an amount equal to all dividends
         accrued but unpaid thereon calculated in accordance with Section 2(a)
         hereof through the date of the liquidation, dissolution or winding up
         of the Corporation or redemption of the Preferred Stock, as the case
         may be.

                  (b) Remaining Assets. If the assets of the Corporation
         available for distribution to the Corporation's stockholders exceed the
         aggregate amount payable to the holders of the Preferred Stock pursuant
         to Section 3(a) hereof, then after the payments required by Section
         3(a) shall have been made or irrevocably set apart, such assets shall
         be distributed equally among the holders of Common Stock on a per share
         basis.

                  (c) Reorganization. A consolidation or merger of the
         Corporation with or into any other corporation or corporations or sale,
         lease or transfer of all or substantially all of the assets of the
         Corporation or its subsidiaries in one or more transactions to a third
         party shall be deemed a liquidation, dissolution, or winding up of the
         Corporation as those terms are used in this Section 3 except for any
         such transaction with the Corporation and/or any wholly-owned
         subsidiary or subsidiaries of the Corporation.

                  Section 4. Redemptions.

                  (a) Stockholder Optional Redemption. On any date other than a
         Saturday, Sunday or day in which banking institutions in New York, New
         York are required or permitted to be closed for business (the
         "Stockholder Redemption

                                       2
   5
         Date"), the holders of the Preferred Stock, shall have the right to
         cause the Corporation to redeem their shares of Preferred Stock at the
         Redemption Price (as defined in Section 4(c)). Holders of the Preferred
         Stock electing to so redeem such Preferred Stock shall request
         redemption by at least twenty (20) days' prior written notice given to
         the Corporation specifying the Stockholder Redemption Date, that
         portion of such Preferred Stock the holder thereof elects to redeem and
         surrendering to the Corporation the certificate or certificates
         representing such Preferred Stock. Upon proper receipt of such
         election(s) and the certificates representing such Preferred Stock, the
         Corporation will be obligated to redeem the number of shares of
         Preferred Stock specified therein at the Redemption Price on the
         Stockholder Redemption Date. Thereupon, the Redemption Price for such
         shares shall be payable to the order of the person whose name appears
         on such certificate or certificates as the owner thereof, and each
         surrendered certificate shall be cancelled and retired. In the event
         less than all of the shares represented by such certificate are
         redeemed, a new certificate shall be issued representing the unredeemed
         shares. In the event the Corporation does not have funds legally
         available to purchase all of the shares of Preferred Stock on the
         Stockholder Redemption Date which the holders thereof have requested
         the Corporation to purchase under this Section 4(a), the Corporation
         shall purchase the remainder of such Preferred Stock as soon as it has
         funds legally available to do so and, if more than one holder of
         Preferred Stock has so elected for redemption, then, as funds become so
         available therefor, the Corporation will redeem shares pro rata among
         the electing holders of shares of Preferred Stock (based on the number
         of shares of Preferred Stock held by each such holder).

                  (b) Corporation Optional Redemption. On any date other than a
         Saturday, Sunday or day in which banking institutions in New York, New
         York are required or permitted to be closed for business, so long as
         any shares of Preferred Stock shall be outstanding and to the extent
         the Corporation shall have funds legally available for such payment,
         the Corporation shall have the right to redeem all or any portion of
         such shares then outstanding. The shares to be redeemed shall be
         determined pro rata among the holders of shares of the Preferred Stock
         (based on the number of shares of Preferred Stock held by each holder).

                  The Corporation shall, not less than 30 days nor more than 60
         days prior to any redemption date pursuant to this Section 4(b), mail
         written notice ("Redemption Notice"), postage prepaid, to each holder
         of shares of record of Preferred Stock to be redeemed at such holder's
         post office address last shown on the records of the Corporation. The
         Redemption Notice shall state:

                  (i) The number of shares of Preferred Stock held by the holder
         which the Corporation intends to redeem;

                  (ii) The Redemption Price of the Preferred Stock which the
         Corporation intends to redeem; and

                                       3
   6
                  (iii) The date, time, place and manner in which the holder is
         to surrender to the Corporation the certificate or certificates
         representing the shares of Preferred Stock to be redeemed.

                  On or before the scheduled redemption date, each holder of
         Preferred Stock to be redeemed shall surrender the certificate or
         certificates representing such shares to the Corporation, in the manner
         and at the place designated in the Redemption Notice, and thereupon the
         Redemption Price for such shares shall be payable to the order of the
         person whose name appears on such certificate or certificates as the
         owner thereof, and each surrendered certificate shall be cancelled and
         retired. In the event less than all of the shares represented by such
         certificate are redeemed, a new certificate shall be issued
         representing the unredeemed shares.

                  (c) Price. The respective redemption price for shares of
         Preferred Stock (the "Redemption Price") under Sections 4(a) or 4(b)
         hereof shall be an amount per share equal to the Liquidation Preference
         of the Preferred Stock determined in accordance with Section 3(a)
         hereof.

                  (d) Dividends After Redemption Date. No shares of Preferred
         Stock are entitled to any dividends accruing after the specified
         redemption date for such Preferred Stock unless the Corporation shall
         default in the payment of the Redemption Price for such shares of
         Preferred Stock. On such date all rights of the holder or holders of
         such shares of Preferred Stock will cease, and such shares will be
         deemed not to be outstanding and will be deemed to represent only the
         right to receive the applicable Redemption Price.

                  Section 5. Voting Rights.

                  (a) Except as specifically set forth herein and as otherwise
         required under Delaware law, the holders of Preferred Stock shall not
         be entitled or permitted to vote on any matter required or permitted to
         be voted upon by the stockholders of this Corporation. In any case in
         which the holders of Preferred Stock shall be entitled to vote pursuant
         to Delaware law, each holder of Preferred Stock shall be entitled to
         one vote for each share of Preferred Stock held. Votes or consents of
         holders of shares of Preferred Stock may be given in person or by
         proxy, either in writing or by resolution adopted at an annual or
         special meeting called for such purposes.

                  In addition to any other rights provided by law, the
         Corporation shall not, without first obtaining the affirmative vote or
         written consent of the holders of at least 66-2/3% of the then
         outstanding aggregate number of shares of Preferred Stock (excluding
         for these purposes shares owned by this Corporation and its
         subsidiaries):

                  (A) amend, alter or repeal the preferences, special rights or
                  other powers of the Preferred Stock so as to effect adversely
                  the Preferred Stock and, for this purpose, the authorization
                  or issuance by the Corporation of any securities with
                  preference or priority over, or being on a parity with the
                  Preferred Stock as to the right to receive either dividends or
                  amounts distributable upon liquidation, dissolution or winding
                  up of the Corporation shall be deemed so to effect adversely
                  the Preferred Stock; or

                  (B) authorize or effect the redemption or repurchase of any
                  capital stock of the Corporation other than the Preferred
                  Stock or rights to acquire capital stock of the Corporation
                  other than the Junior Stock (as hereinafter defined). For
                  purposes hereof, "Junior Stock" shall mean all shares of
                  Common Stock and any other class or series of capital stock of
                  the Corporation not entitled to receive any dividends until
                  the Preferred Stock shall have received the Preference Amount
                  determined as of the time such dividend is to be made and, for
                  purposes of Section 3 hereof, any class or series of capital
                  stock of the Corporation not entitled to receive any assets
                  upon liquidation, dissolution or winding up of the affairs of
                  the Corporation until the Preferred Stock shall have received
                  the entire amount to which such stock is entitled upon such
                  liquidation, dissolution or winding up.

                  (b) Common Stock. Each holder of shares of Common Stock shall
         be entitled to one vote for each share thereof held.

                  Section 6. Senior Securities. The Preferred Stock shall not
         rank junior to any other classes or series of capital stock of the
         Corporation in respect of the right to receive dividends or the right
         to participate in any distribution upon liquidation, dissolution or
         winding up of the Corporation.

                  Section 7. Exclusion of Other Rights. Except as may otherwise
         be required by law and for the equitable rights and remedies that may
         otherwise be available to holders of Preferred Stock, the shares of
         Preferred Stock shall not have any designations, preferences,
         limitations or relative rights, other than those specifically set forth
         in the Certificate of Incorporation of the Corporation.
