                            CONVERSION AGREEMENT
                            --------------------

        THIS CONVERSION AGREEMENT ( the "AGREEMENT") is being executed
   and delivered as of this 13th day of July, 2000 by and among Jalo
   Paananen, Elmar Paananen, Annamari Jukko and Topi Paananen, individual
   residents of the Republic of Finland (each a "FINLAND HOLDER" and,
   collectively, the "FINLAND HOLDERS"), Eimo Oyj, a company organized
   under the laws of the Republic of Finland ("PARENT"), and Triple S
   Plastics, Inc., a Michigan corporation (the "COMPANY").

        Reference is hereby made to the Agreement and Plan of Merger,
   dated as of July 13, 2000 (the "MERGER AGREEMENT"), among the Company,
   Parent, and Spartan Acquisition Corp., a Michigan corporation and a
   wholly-owned subsidiary of Parent (the "MERGER SUB"). All capitalized
   terms used herein but not separately defined shall have the meanings
   assigned to them in the Merger Agreement. Reference is hereby further
   made to the form of Lock-Up Agreement attached as Exhibit 1.6(e) to
   the Merger Agreement (the "LOCK-UP AGREEMENT").

                            W I T N E S S E T H:

        WHEREAS, the Merger Agreement provides for the acquisition by
   Parent of all of the issued and outstanding Shares of the Company
   through the merger of Merger Sub with and into the Company, upon the
   terms and subject to the conditions set forth in the Merger Agreement;


        WHEREAS, each Finland Holder is the beneficial owner of that
   number of Series K Shares of Parent set forth in Exhibit A attached
   hereto; and

        WHEREAS, as an inducement and a condition to the Company's
   entering into the Merger Agreement, the Company has required that the
   Finland Holders agree, and the Finland Holders have agreed, to cause
   all of their Series K Shares to be converted into Parent Ordinary
   Shares on a one-for-one basis, such conversion to be conditioned upon
   and effective as of the occurrence of the Effective Time;

        NOW, THEREFORE, the undersigned hereby agree as follows:

        1.   CONVERSION OF SERIES K SHARES.  As permitted under the terms
   of Article 4 of Parent's Articles of Association ("ARTICLE 4"), each
   of the Finland Holders shall as promptly as practicable send a written
   demand to Parent (each, a "CONVERSION DEMAND") requiring that Parent
   effect the conversion of the Series K Shares held by such Finland
   Holder into Parent Ordinary Shares on a one-for-one basis (i.e., each
   Series K Share shall be converted into one Series A Share), such
   conversion to be effective as of the Effective Time under the Merger
   Agreement.  Each Conversion Demand shall be in the form and shall
   contain all information required by Article 4 and applicable Finnish
   law. Promptly following receipt of the Conversion Demands, Parent
   shall prepare an application to the Trade Register for Parent (the
   "REGISTER APPLICATION") requesting the conversion of Series K Shares







   subject to the Conversion Demands into Parent Ordinary Shares on a
   one-for-one basis.  On or immediately following the Closing Date,
   Parent shall cause the Register Application to be filed with the Trade
   Register for Parent and request that the Trade Register effect such
   conversion as soon as possible under applicable Finnish law.

        2.   TERM.  This Agreement shall terminate and be of no further
   force or effect automatically upon any termination of the Merger
   Agreement.

        3.   REPRESENTATIONS AND WARRANTIES. Each of Finland Holders
   hereby represents and warrants, as of the date hereof, to the Company
   and Parent as follows:

             (a)  AUTHORIZATION; VALIDITY OF AGREEMENT.  Such Finland
   Holder has full power and authority to execute and deliver this
   Agreement, and to consummate the transactions contemplated hereby.
   This Agreement has been duly executed and delivered by the Finland
   Holder and, assuming due and valid authorization, execution and
   delivery thereof by Parent and the Company, this Agreement is a valid
   and binding obligation of the Finland Holder enforceable against the
   Finland Holder in accordance with its terms, subject to applicable
   bankruptcy, insolvency, moratorium and other similar laws relating to
   creditors' rights and general principles of equity.

             (b)  CONSENTS AND APPROVALS; NO VIOLATIONS.  None of the
   execution, delivery or performance of this Agreement by the Finland
   Holder or the consummation by the Finland Holder of the transactions
   contemplated hereby will (i) other than the filing with the Trade
   Register of Parent described herein, require any filing with, or
   permit, authorization, consent or approval of, any Governmental
   Entity, or (ii) violate any Order, statute, rule or regulation
   applicable to the Finland Holder. There are no third party consents or
   approvals required to be obtained by any Finland Holder prior to the
   consummation of the transactions contemplated hereby.

             (c)  SHARE OWNERSHIP.  Each of the Finland Holders owns all
   right, title and interest in and to that number of the Series K Shares
   set forth opposite its name on Exhibit A hereto, and such Series K
   Shares collectively represent all of the Series K Shares issued and
   outstanding.  Other than the Series K Shares set forth on such Exhibit
   A, no Series K Shares are issued or outstanding.

        4.   RELIANCE.  The Finland Holders understand and acknowledge
   that the Company is entering into the Merger Agreement in reliance
   upon the Finland Holders execution and delivery of this Conversion
   Agreement and the consummation of the transactions contemplated by
   this Conversion Agreement.

        5.   SPECIFIC PERFORMANCE.  Each of the Finland Holders
   recognizes and acknowledges that a breach by it of any covenants or
   agreements contained in this Conversion Agreement will cause the

                                          2







   Company to sustain damages for which it would not have an adequate
   remedy at law for money damages, and therefor in the event of any such
   breach the Company shall be entitled to the remedy of specific
   performance of such covenants and agreements and injunctive and other
   equitable relief in addition to any other remedy to which it may be
   entitled at law or in equity.  All rights, powers and remedies
   provided under this Conversion Agreement or otherwise available in
   respect hereof at law or in equity shall be cumulative and not
   alternative, and the exercise of any by the Company shall not preclude
   the simultaneous or later exercise of any other such right, power or
   remedy by it.

        6.   FURTHER ASSURANCES.  From time to time, at the Company's
   request and without further consideration, each of the undersigned
   shareholders shall execute and deliver such additional documents and
   take all such further lawful action as may be reasonably necessary or
   desirable to consummate and make effective in the most expeditious
   manner practicable, the transactions contemplated by this Conversion
   Agreement.

        IN WITNESS WHEREOF, the parties have executed this Agreement as
   of the date first above written.
