          AGREEMENT AND PLAN OF MERGER dated as of December 26, 1986 between
PRODUCT DESIGN & ENGINEERING, INC. (the "Company"), a Minnesota corporation, and
PDE ACQUISITION CORP. ("PDE"), a Minnesota corporation.

          WHEREAS, the Company was incorporated in Minnesota in 1955, and its
authorized capital stock consists of 5,000,000 shares of common Stock, par value
$.10 per share ("Company Common Stock"), of which (as of the close of business
on December 24, 1986) 853,628 shares were issued and outstanding and no shares
were held by the Company as treasury stock;

          WHEREAS, PDE was incorporated in Minnesota in 1986, and its authorized
capital stock consists of 1,000 shares of Common Stock, par value of $.10 per
share ("PDE Common Stock"), all of which are issued and outstanding and are
owned by Specialty Packaging Products, Inc. ("Specialty"), a Virginia
corporation;

          WHEREAS, the Company, certain principal shareholders of the Company,
PDE and Specialty have entered into an Agreement and Plan of Reorganization
dated as of November 26, 1986 ("Reorganization Agreement") providing for certain
representations, warranties and agreements in connection with the transactions
contemplated therein and herein; and

          WHEREAS, the boards of directors of the Company, PDE and Specialty
have determined that it is in the best interests of each of the Company and PDE
and their respective shareholders that, upon the terms and conditions contained
herein, the Company and PDE be merged, and each share of the Company Common
Stock outstanding at the time of the merger be converted into a right to receive
$12.00 in cash;

          NOW, THEREFORE, in consideration of the mutual agreements and
covenants contained herein, the parties hereto agree that the Company and PDE
shall be merged and that the terms and conditions of such merger and the mode of
carrying the same into effect shall be as follows:

1.  MERGER AND SURVIVING CORPORATION.

          A. Pursuant to the applicable laws of the State of Minnesota, PDE
shall merge with and into the Company, and the Company shall be the surviving
corporation after the merger and shall continue to exist as a corporation
created and governed by the laws of the State of Minnesota.

<Page>

          B. Except as amended by this Agreement, the Articles of Incorporation
of the Company in effect immediately prior to the merger becoming effective
shall be the Articles of Incorporation of the surviving corporation.

          C. The By-Laws of the Company in effect immediately prior to the
merger becoming effective shall be the By-Laws of the surviving corporation
until altered, amended or repealed in accordance with the Articles of
Incorporation of the surviving corporation and applicable law.

2.  EFFECTIVENESS OF MERGER.

          A. If this Agreement has been adopted and approved by the shareholders
of the Company and PDE and, if all of the conditions precedent to the
obligations of each of such corporations as set forth in the Reorganization
Agreement shall be satisfied or have been waived, articles of merger executed by
duly authorized officers of each of the Company and PDE, complying in all
respects with the Minnesota Business Corporation Act ("Minnesota Law"), shall be
filed with the Secretary of State of Minnesota.

          B. The merger contemplated herein shall become effective upon the
filing of duly executed articles of merger with the Secretary of State of the
State of Minnesota. The time when the merger shall become effective is referred
to in this Agreement as the "Time of Merger".

3.  SHARES OF CONSTITUENT AND SURVIVING CORPORATIONS.  The manner and basis of
converting the Company Common Stock into cash and the PDE Common Stock into
Company Common Stock shall be as follows:

          A. Section 5 of the Articles of Incorporation of the Company shall be
amended to read as follows:

               "The total number of shares of capital stock which the
          Corporation shall have authority to issue is 1,000 shares of common
          stock, with par value of $.10 per share."

          B. Each share of PDE Common Stock outstanding at the Time of Merger
shall be converted into one fully paid and nonassessable share of the Company
Common Stock.

          C. Each share of the Company Common Stock outstanding at the Time of
Merger shall, by virtue of the merger and without any action on the part of the
holder thereof, be

                                       -2-
<Page>

converted into the right to receive, upon surrender of the certificate
representing such share, $12.00 in cash payable to the holder thereof, without
interest thereon. Each share of the Company Common Stock, if any, held by the
Company as treasury stock or held by Specialty or PDE at the Time of Merger
shall be cancelled.

          D. Anything herein to the contrary notwithstanding, any holder of
shares of the Company Common Stock who shall exercise the rights of a dissenting
shareholder pursuant to the provisions of Sections 302A.471 and 302A.473 of the
Minnesota Law shall be entitled to receive only the payment therein provided for
and shall not be entitled to receive the consideration described in Section 3.C.
Such payment shall be made directly by the Company, as the surviving
corporation, and not out of the Exchange Fund (as hereinafter defined).

4.  EXCHANGE ARRANGEMENTS.

          A. At or prior to the Time of Merger, PDE shall deposit in cash with
Mellon Securities Transfer Services (the "Exchange Agent"), in trust, an amount
equal in the aggregate to the product of (i) the number of shares of the Company
Common Stock issued and outstanding at the Time of Merger less shares held by
Specialty and PDE, and (ii) $12.00 (such product being hereinafter referred to
as the "Exchange Fund"). Out of the Exchange Fund, the Exchange Agent shall,
pursuant to irrevocable instructions, make the payments provided for in Section
3.C. above and this Section 4. The Exchange Fund shall not be used for any other
purpose, except as provided in the Exchange Agreement entered into among the
Exchange Agent, the Company and PDE.

          B. Promptly after the Time of Merger, the Exchange Agent shall mail to
each record holder, as of the Time of Merger, of an outstanding certificate or
certificates, which prior thereto represented shares of the Company Common
Stock, a form letter of transmittal (which shall specify that delivery shall be
effected, and risk of loss and title to such certificate or certificates shall
pass, only upon proper delivery of such certificate or certificates to the
Exchange Agent) and instructions for use in effecting the surrender of such
certificate or certificates for payment. Upon surrender to the Exchange Agent of
such certificate or certificates, together with such letter of transmittal, duly
executed, the Exchange Agent shall promptly pay out of the Exchange Fund to the
person entitled thereto the amount to which such person is entitled, as provided
in Section 3.C. No interest will be paid or accrued on the cash payable upon the
surrender of the certificate or certificates. If payment is to be made to a

                                       -3-
<Page>

person other than the one in whose name the certificate surrendered is
registered, it shall be a condition of payment that the certificate so
surrendered shall be properly endorsed or otherwise in proper form for transfer
and that the person requesting such payment shall pay any transfer or other
taxes required by reason of the payment to a person other than the registered
holder of the certificate surrendered or establish to the satisfaction of the
Company, as the surviving corporation, that such tax has been paid or is not
applicable. Until surrendered in accordance with the provisions of this Section
4, the certificate or certificates which immediately prior to the Time of Merger
represented issued and outstanding shares of the Company Common Stock (except
for certificates representing shares with respect to which appraisal rights have
been perfected to the extent then required pursuant to Section 302A.473 of the
Minnesota Law) shall represent for all purposes the right to receive $12.00 in
cash multiplied by the number of shares evidenced by such certificate or
certificates. After the Time of Merger, there shall be no further registration
of transfers on the records of the Company of shares of the Company Common
Stock.

               (1) If after the Time of Merger the Company, as the surviving
          corporation, settles an appraisal proceeding brought pursuant to
          Section 302A.473 of the Minnesota Law and thereby becomes the holder
          of shares of the Company Common Stock, or if pursuant to a decree of a
          court of competent jurisdiction in such a proceeding the Company, as
          the surviving corporation, receives shares of the Company Common Stock
          upon payment of the appraised value thereof, then in either such
          event, the Company may surrender the certificate or certificates
          representing such shares to the Exchange Agent for payment of the
          amount provided for in Section 3.C.

               (2) Any portion of the Exchange Fund deposited with the Exchange
          Agent which remains unclaimed by the shareholders of the Company for
          ninety (90) days after the date of the Time of Merger shall be repaid
          to the Company, as the surviving corporation, upon demand, and any
          shareholder of the Company who has not theretofore complied with this
          Section 4 shall thereafter look only to the Company for payment of his
          claim for $12.00 for each of his Company Common Shares.

5.  EFFECT OF MERGER.  At the Time of Merger:

               A. The separate existence of PDE shall cease.

               B. The Company shall have all the rights, privileges, immunities
and powers and shall be subject to all of the duties

                                       -4-
<Page>

and liabilities of a corporation organized under the Minnesota Law and shall
possess all the rights, privileges, immunities, powers and franchises as well as
of a public or a private nature of each of the Company and PDE; and all the
property, real, personal and mixed, and franchises of each of the Company and
PDE, and all debts due on whatever account to any of them, including
subscriptions to shares and all other chooses in action belonging to any of
them, shall be taken and deemed to be transferred to and vested in the Company
without further act or deed; and title to any real estate or any interest
therein, under the laws of the State of Minnesota vested in the Company or PDE
shall not revert or be in any way impaired by reason of the merger. The Company
shall, after the Time of Merger, be responsible and liable for all the
liabilities and obligations of each of the Company and PDE as if the Company had
itself incurred the same or contracted therefor, but the liabilities of such
corporations, or of their shareholders, directors, or officers, shall not be
affected, nor shall the rights of the creditors thereof or of any persons
dealing with such corporations or any liens upon the property of such
corporations, be impaired by the merger, but such liens shall be limited to the
property upon which they were liens immediately prior to the Time of Merger. Any
claim existing or action or proceeding pending by or against the Company or PDE
may be prosecuted to judgment as if such merger had not taken place, or the
Company may be proceeded against or substituted in place of PDE.

6.  FURTHER ASSURANCES.

          From time to time as and when requested by the Company or by its
successors or assigns, PDE and its proper officers and directors shall execute
and deliver, or cause to be executed and delivered, all deeds and other
instruments and shall take or cause to be taken all such other and further
actions as the Company, as the surviving corporation, may deem necessary or
appropriate in order more fully to vest in and confirm to the Company title to
and possession of all the property, rights, privileges, powers and franchises
referred to in Section 5.B. and otherwise to carry out the intent and purposes
of this Agreement.

7.  AMENDMENT.

          The Company and PDE may, by agreement in writing authorized by their
respective Boards of Directors, amend this Agreement at any time before or after
adoption hereof by the shareholders of either or both, but after any such
adoption, no amendment shall be made which substantially changes the terms
hereof without the further approval of such shareholders.

8.  TERMINATION.

          A. The Company may terminate this Agreement by notice to PDE at any
time prior to the Time of Merger, whether before or after adoption by the
shareholders of the Company and PDE, if a condition to the performance of the
Company hereunder shall not be fulfilled at or before the time specified for the
fulfillment thereof.

          B. PDE may terminate this Agreement by notice to the Company at any
time prior to the Time of Merger, whether before or after adoption by the
shareholders of the Company and PDE, if a condition to the performance of PDE
hereunder shall not be fulfilled at or before the time specified for the
fulfillment thereof.

the parties hereunder if the Reorganization Agreement is terminated pursuant to
and in accordance with Section 12.01 of the Reorganization Agreement.
