                               EXPLANATORY NOTE

     References to "Eimo" and the "Registrant" mean Eimo Oyj, a corporation
organized under the laws of Finland. References to "Triple S" mean Triple S
Plastics, Inc., a Michigan corporation.

     Under an Amended and Restated Agreement and Plan of Merger, dated as of May
25, 2001, by and among Eimo, Triple S, Spartan Acquisition Corp., a wholly-owned
subsidiary of Eimo ("Spartan"): (i) Spartan will merge with and into Triple S
(the "Merger"), with Triple S surviving as a wholly-owned subsidiary of Eimo,
and (ii) each outstanding share of common stock of Triple S (the "Triple S
Common Stock") will be canceled in exchange for the right to receive 4.5 Series
A shares of Eimo accounting counter value (Euro) 0.25 each (the "Eimo Series A
shares"). The Eimo Series A shares will be issued in the form of American
Depositary Shares (the "Eimo ADSs"). At the time of the merger, each Eimo ADS
will represent ten Eimo Series A shares or such lesser number of Eimo Series A
shares as Eimo may elect. The Merger will be effective on or about August 15,
2001 (the time the Merger is effective is hereinafter referred to as the
"Effective Time").

     At the Effective Time, all options to purchase shares of Triple S Common
Stock (the "Triple S Options") which are then outstanding and unexercised will
cease to represent a right to acquire Triple S Common Stock and all Triple S
Options will be converted into options to acquire Eimo Series A shares which are
to be issued in the form of Eimo ADSs.

     The Company hereby amends its Registration Statement on Form F-4 (333-
13154) by filing this Post-Effective Amendment No. 3 on Form S-8 relating up to
2,068,650 Eimo Series A shares, issuable in substitution for Triple S Common
Stock previously issuable upon the exercise of options originally granted or
pursuant to the terms of the following plans of Triple S (the "Triple S Plans"):

     .  Triple S Plastics, Inc. Amended and Restated Employee Stock Option Plan;
        and
     .  Triple S Plastics, Inc. Amended and Restated Outside Director Stock
        Option Plan.

Such Eimo Series A shares will now be issued pursuant to the Eimo 2001
Substitute Option Plan and two sub-plans, the "Eimo Oyj Stock Option Plan For
Outside Directors Of Triple S, Inc. In Replacement Of The Triple S Plastics,
Inc. Outsider Director Stock Option Plan" and the Eimo Oyj Stock Option Plan For
Employees Of Triple S Plastics, Inc. In Replacement Of The Triple S Plastics,
Inc. Employee Stock Option Plan.

     All such Eimo Series A shares issuable hereunder were previously registered
on the Form F-4 but will be issued pursuant to this Post-Effective Amendment No.
3 on Form F-8.

Item 4. Description of Securities.
- ------- --------------------------

Not applicable.

Item 5. Interests of Named Experts and Counsel.
- ------- ---------------------------------------

        The financial statements and schedules incorporated by reference in this
Registration Statement have been audited by Grant Thornton Finland, independent
public accountants, to the extent and for the periods set forth in their reports
incorporated herein by reference, and are incorporated herein in reliance upon
such report given upon the authority of said firm as experts in auditing and
accounting.

        The opinion of the validity of the securities being offered incorporated
by reference in this Registration Statement has been issued by Asianajotoimisto
Farkkila, Haapanen, Lunkka & Rautialia Oy, independent legal counsel, to the
extent and for the periods set forth in its opinion incorporated herein by
reference, and are incorporated herein in reliance upon such opinion given upon
the authority of said firm as counsel for the Registrant giving an opinion upon
the validity of the securities being registered

Item 6. Indemnification of Officers and Directors.
- ------- ------------------------------------------

        Finnish corporate law does not address the question of whether a
corporation may, in advance, agree to indemnify its directors and officers for
costs and expenses incurred by them as a result of suits or claims arising out
of their past or future service to the corporation. Market practice in Finland
has been to not include any specific indemnity provisions in the articles of
association of publicly listed corporations, but rather to retroactively
discharge the directors and officers of the corporation from any and all
liabilities relating to their activities on behalf of the corporation by
proposing resolutions to that effect for the consideration of shareholders at
the annual general meeting and through the establishment of directors and
officers' insurance plans. Adoption of a resolution in favor of indemnification
by the shareholders prevents the corporation from bringing a lawsuit against the
director or officer based on facts that the corporation or the shareholders were
aware of at the time of the adoption of the resolution. However, shareholders
may bring a suit against the officers or directors in the name of the
corporation based on facts they were not aware of at the time of the adoption of
the resolution. In addition, shareholders may, despite the adoption of the
resolution, bring a suit in the name of the corporation if a director or officer
has caused damage directly to the shareholders.

Item 7. Exemption From Registration Claimed.

Not applicable.

Item 9.    Undertakings.
- -------    -------------

       (a)   The undersigned Registrant hereby undertakes:

             (1)  To file, during any period in which offers or sales are being
made, a further post-effective amendment to this Registration Statement;

                  (i)    To include any prospectus required by Section 10(a)(3)
of the Securities Act of 1933;

                  (ii)   To reflect in the prospectus any facts or events
arising after the effective date of the Registration Statement (or the most
recent post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth in the
Registration Statement; and

                  (iii)  To include any material information with respect to the
plan of distribution not previously disclosed in the Registration Statement or
any material change to such information in the Registration Statement.


          (2)  That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment will be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time will be deemed to be the initial bona
fide offering thereof.

          (3)  To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

     (b)  The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each such post-
effective amendment and each filing of the registrant's annual report pursuant
to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 that is
incorporated by reference in the Registration Statement will be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time will be deemed to be the initial bona
fide offering thereof.

     (c)  To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     (d)  Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.


                                   SIGNATURES

     Pursuant to the requirements of the Securities Act of 1933, the Registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-8 and has duly caused this Post-Effective
Amendment No. 3 on Form S-8 to its Registration Statement on Form F-4 (No.
13154) to be signed on its behalf by the undersigned, thereunto duly authorized
in the City of Lahti, Republic of Finland, on the 15/th/ day of August, 2001.
