   Agreement is hereby amended by striking such section in its entirety
   and inserting in lieu thereof the following:

                  (c)  The Original Agreement is hereby further modified
   as necessary to reflect that the Exchange Ratio is fixed.

                  (d)  Section 5.6(c) is hereby amended by inserting at

   lieu thereof the following:





                       "(a)  As of the Effective Time (i) each
             outstanding Company Employee Stock Option, and any other
             Company Option (together, the "Adjusted Options") shall be
             exchanged for an option to purchase the number of Parent
             ADSs derived by multiplying the number of Shares subject to
             such Company Employee Stock Option or other Company Option
             immediately prior to the Effective Time by the Exchange
             Ratio and dividing the result by two (rounded to the nearest
             whole number of Parent ADSs), at an exercise price per
             Parent ADS equal to (X) the exercise price for each such
             Share subject to such option (Y) divided by the Exchange
             Ratio (Z) with the result multiplied by two (rounded down to
             the nearest whole cent), and all references in each such
             option to the Company shall be deemed to refer to Parent,
             where appropriate, and (ii) Parent shall assume the
             obligations of the Company under the Company Stock Plans.
             The other terms of each Adjusted Option, and the plans under
             which they were issued, shall continue to apply in
             accordance with their terms, subject to SECTION 5.7(d)."

             "5.14     GOVERNANCE MATTERS.  Prior to the Effective Time,
        the Board of Directors of Parent shall take all necessary action
        to (i) cause the resignations of (or will cause the removal of,
        if resignations are not tendered) of Elmar Paananen plus one
        other current Director of Parent as directors of Parent, and
        (ii) appoint A. Christian Schauer, Daniel B. Canavan and Evan C.
        Harter, to serve as members of such Board of Directors of Parent,
        effective as of the Effective Time, until the first annual
        meeting of Parent Shareholders following the Effective Time.
        Further, in connection with the 2001 annual meeting of Parent
        shareholders, the Board of Directors of Parent shall take all
        necessary action to nominate seven persons to serve on the Board

        meeting of Parent shareholders, which nominees shall include A.
        Christian Schauer, Daniel B. Canavan and Evan C. Harter. There is
        no commitment or obligation of Parent or its shareholders
        whatsoever regarding the members of the Board of Directors of
        Parent from and after the 2002 annual meeting of Parent
        Shareholders."

                  (g)  Section 7.1(d)(i) shall be amended striking the

                                      2





                  (h)  Section 7.3, PAYMENT OF CERTAIN FEES AND EXPENSES,
   shall be amended by striking Section 7.3(b) in its entirety and
   inserting in lieu thereof the following:

                       "(b)  If this Agreement is terminated by Parent in
             accordance with SECTION 7.1(b)(i) as a result of a willful
             breach by the Company, or is terminated by Parent in
             accordance with SECTION 7.1(b)(ii), or SECTION 7.1(b)(iii),
             then the Company shall pay to Parent the Termination Fee and
             its Expenses.  If this Agreement is terminated by Parent in
             accordance with SECTION 7.1(b)(iv), then Parent shall pay to
             the Company the Termination Fee and its Expenses.  If this
             Agreement is terminated by Parent in accordance with SECTION
             7.1(b)(i) hereof as a result of a non-willful breach by
             Company, then the Company shall pay to Parent its Expenses."

                  (i)  Section 8.1, DEFINITIONS, is hereby amended by
   adding the following definition:

             "Parent Average Price" shall mean the average, for a period
        consisting of the fifteen (15) consecutive Trading Days ending on
        (and including) the last Trading Day prior to the Company
        Shareholders Meeting (as herein defined), of the volume-weighted
        daily average price, as reported in the Financial Times, U.S.
        Edition, or if not reported therein, another authoritative
        source, expressed in Euros for a single Parent Ordinary Share on
        the HSE, converted into U.S. Dollars at the Exchange Rate for
        such date."

             2.   CONFIRMATION OF ADS RATIO.  The parties confirm that
   they have agreed that each Parent ADS shall represent two Parent
   Ordinary Shares.

             3.   CONFIRMATION OF AGREEMENT.  Except as otherwise set
   forth herein, the Original Agreement shall continue in full force and
   effect.  All capitalized terms not defined herein which are defined in
   the Original Agreement shall have the meaning ascribed to them in the
   Original Agreement.

             4.   COUNTERPARTS, TELECOPIER.  This Amendment Number One to
   the Original Agreement and Amendment Number One to the Lock-Up
   Agreement referred to herein may be executed in one or more
   counterparts, all of which together shall be considered one and the
   same agreement. Transmission by telecopier of an executed counterpart
   of a signature page to this Amendment Number One and Amendment Number
