                  Act of 1934, as amended (the "Exchange Act"), since December

Item 4.  Description of Securities.

         Not applicable.

Item 5.  Interests of Named Experts and Counsel.

         Not applicable.

Item 6.  Indemnification of Directors and Officers.

         Under Finnish corporate law, directors may become personally liable to
the corporation for damages caused to shareholders based on negligence or
intentional acts. Personal liability to a third party, including creditors,
employees and contractors of the company, requires, in addition to negligence or
an intentional act, a breach of a provision of the Finnish corporate law or the
corporation's articles of association. Under Finnish law, directors and officers
must discharge their duties with that degree of care and skill that an "ordinary
prudent person" would exercise under similar circumstances in like position, and
breach of this standard constitutes negligence. Courts will not second guess the
business judgments of directors and officers if exercised in good faith on the
basis of available information.

         Finnish corporate law does not address the question of whether a
company 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 company. Market practice in Finland has been
not to include any specific indemnity provisions in the articles of association
of publicly listed companies, but rather to retroactively discharge the
directors and officers of the company from any and all liabilities relating to
their activities on behalf of the company by proposing resolutions to that
effect for the consideration of shareholders at the annual meeting and through
establishment of directors and officers insurance plans. Adoption of a
resolution in favor of indemnification by the shareholders prevents the company
from bringing a lawsuit against the director or officer based on facts that the
company 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 company based on the 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 company
if a director of officer has caused damage directly to the shareholders.

Item 7.  Exemption From Registration Claimed.

         Not applicable.

Item 8.  Exhibits.

         (a)      Exhibits. See the Exhibit Index immediately following the
                  signature page hereto.

         (b)      Undertaking. The undersigned Registrant hereby undertakes that
                  it will submit or has submitted the Plans and any amendments
                  thereto to the Internal Revenue Service ("IRS") in a timely
                  manner and will make or has made all changes required by the
                  IRS in order to qualify the Plans under Section 401 of the
                  Internal Revenue Code of 1986, as amended.

Item 9.  Undertakings.

         The undersigned Registrant hereby undertakes:

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

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

                  (ii)   To reflect in the prospectus any facts or events
                         arising after the effective date of this 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 this Registration Statement; and

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

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Commission by the Registrant pursuant to Section 13 or 15(d) of the Exchange Act
that are incorporated by reference in this Registration Statement.

                  (2) That, for the purpose of determining any liability under
the Securities Act, each such post-effective amendment shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall 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) That, for purposes of determining any liability under the
Securities Act, each filing of the Registrant's annual report pursuant to
Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing
of the employee benefit plan's annual report pursuant to Section 15(d) of the
Exchange Act) that is incorporated by reference in this Registration Statement
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

         (c) Insofar as indemnification for liabilities arising under the
Securities Act 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 Commission such
indemnification is against public policy as expressed in the Securities 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 Securities Act and will be governed by the final
adjudication of such issue.
