     NOW, THEREFORE, in consideration of the foregoing and the mutual
representations, warranties, covenants and agreements herein contained, and
intending to be legally bound hereby, the parties hereto agree as follows:

                                   I. ARTICLE

                                     VOTING

A.      Agreement to Vote.  Each Stockholder hereby agrees that it shall, and
shall cause the holder of record on any applicable record date to, from time to
time, at the request of the Parent, at any meeting (whether annual or special
and whether or not an adjourned or postponed meeting) of stockholders of the
Company, however called, (a) if a meeting is held, appear at such meeting or
otherwise cause the Shares to be counted as present thereat for purposes of
establishing a quorum, and (b) vote or consent (or cause to be voted or
consented), in person or by proxy, all Shares, and any other voting securities
of the Company (whether acquired heretofore or hereafter) that are beneficially
owned or held of record by such Stockholder or as to which such Stockholder has,
directly or indirectly, the right to vote or direct the voting, in favor of the
approval and adoption of, and against any action or agreement that would
compete, impede or interfere with the approval and adoption of, the Merger
Agreement, the Merger and any action required in furtherance thereof.

A.      Agreement to Vote.  Each Stockholder hereby agrees that it will not, nor
will it permit any entity under its control to, (a) solicit proxies or become a
"participant" in a "solicitation" (as such terms are defined in Regulation 14A
under the U.S. Securities Exchange Act of 1934, as amended (the "Exchange Act"))
                                                                -------------
in opposition to or in competition with the consummation of the Merger and the
other transactions contemplated by the Merger Agreement or otherwise encourage
or assist any party in taking or planning any action which would compete with or
otherwise serve to interfere with or inhibit the timely consummation of the
Merger in accordance with the terms of the Merger Agreement, (b) directly or
indirectly encourage, initiate or cooperate in a shareholders' vote or action by
consent of the Company's stockholders in opposition to or in competition with
the consummation of the Merger or (c) become a member of a "group" (as such term

securities of the Company for purposes of opposing or competing with the
consummation of the Merger.

A.      Grant of Proxy.  In furtherance and not in limitation of the foregoing,
each Stockholder hereby grants to, and appoints, the Parent and each of Messrs.
Stefan Rover and Andreas Kinsky, in their respective capacities as officers of
the
<PAGE>

Parent, and any individual who shall hereafter succeed any such officer of the
Parent, and any other designee of the Parent, each of them individually, its
irrevocable proxy and attorney-in-fact (with full power of substitution and
resubstitution) to vote the Shares as indicated in this Article I. Each
Stockholder intends this proxy to be irrevocable and coupled with an interest
and will take such further action and execute such other instruments as may be
necessary to effectuate the intent of this proxy. Each Stockholder hereby
revokes any and all previous proxies with respect to such Stockholder's Shares
or any other voting securities of the Company that relate to the approval of the
Merger Agreement.

A.      No Ownership Interest.  Nothing contained in this Agreement shall be
deemed to vest in the Parent any direct or indirect ownership or incidence of
ownership of or with respect to any Shares.  All rights, ownership and economic
benefits of and relating to the Shares shall remain vested in and belong to the
Stockholders, and the Parent shall have no authority to manage, direct,
superintend, restrict, regulate, govern, or administer any of the policies or
operations of the Company or exercise any power or authority to direct the
Stockholders in the voting of any of the Shares, except as otherwise provided
herein, or in the performance of the Stockholders' duties or responsibilities as
stockholders of the Company.

A.      Evaluation of Investment.  Each Stockholder, by reason of its knowledge
and experience in financial and business matters, believes itself capable of
evaluating the merits and risks of the investment in the Parent ADSs and the
Parent Shares underlying such Parent ADSs as contemplated by the Merger
Agreement.

A.      Documents Delivered.  Each Stockholder acknowledges receipt of copies of
the Merger Agreement and all exhibits and schedules thereto.  Each Stockholder
also acknowledges that such Stockholder possesses all the information relating
to the Company and the Parent which such Stockholder deems relevant or material
to such Stockholder's investment in the Parent ADSs and the underlying Parent
Common Stock should the Merger be consummated and to its entering into this
Agreement.

A.      No Inconsistent Voting Agreements.  Each Stockholder hereby covenants
and agrees that, except as contemplated by this Agreement and the Merger
Agreement, the Stockholder (a) has not entered, and shall not enter at any time
while this Agreement remains in effect, into any voting agreement or voting
trust with respect to the Shares and (b) has not granted, and shall not grant at
any time while this Agreement remains in effect, a proxy or power of attorney
with respect to the Shares, in either case, which is inconsistent with such
Stockholder's obligations pursuant to this Agreement.

hereinafter referred to as a "Transfer."
                             ---------

(a) Restrictions on Other Stockholders. Each Stockholder that is not a natural
person, severally and not jointly, hereby agrees not to:

     (i) Transfer any Parent Securities in violation of Rule 145, deeming (for
purposes of this covenant) such Stockholder to be an "affiliate" of the Company
for purposes of such Rules;

     (ii)  Transfer any Parent Securities for a period of 60 calendar days
following the Effective Time without the prior written consent of the Parent;

     (iii)  following such 60 calendar day period, Transfer, in any 90 day

calendar day period referred to above that it has filed a Registration Statement
with the Securities and Exchange Commission with respect to a primary offering
of shares for cash, Transfer any Parent Securities for a period of up to 45 days
from the date of such filing (while preparation for such offering continues) to

<PAGE>

holders generally (such period not to extend more than 14 days prior to the
reasonably expected closing date for such offering or beyond 90 days after the
actual closing of such offering); provided that not more than one such "market
stand-off" period shall be imposed upon the Stockholders in any twelve-month
period.

(a) Share Legends. Each Stockholder consents to the imprinting of a legend on
certificates representing Parent Shares or American Depositary Receipts
representing Parent ADSs of legends reflecting the restrictions set forth in
this Section 4.2.

A.      Incidental or "Piggy-Back" Offering.

(a) During the term of this Agreement, if the Parent proposes to commence an
underwritten public offering in the United States of Parent Shares or the Parent
ADSs that is registered with the U.S. Securities and Exchange Commission (other
than on a Form S-8, S-4 or F-4, or successor form), for the account of any
securityholder of the Parent, then the Parent shall give written notice of such
proposed offering to each of the Stockholders at least twenty (20) days before
the anticipated commencement of such offering, and such notice shall describe
the proposed distribution and offer such Stockholders the opportunity to offer
the number of Parent Shares or Parent ADSs as each such Stockholder may request
(an "Incidental Offering"). The Parent shall use commercially reasonable efforts
(within twenty (20) days of the notice provided for in the preceding sentence)
to cause the managing underwriter or underwriters to permit each of the
Stockholders who have requested in writing to participate in the Incidental
Offering to include its or his Parent Shares or Parent ADSs in such secondary
underwritten offering on the same terms and conditions as the securities of such
other stockholder. The Parent shall not be required to include any such Parent
Shares or Parent ADSs in such secondary underwritten offering unless the
Stockholder thereof accepts the terms of the underwritten offering as agreed
upon between the Parent and the managing underwriter or underwriters, and then
only in such quantity as the managing underwriter or underwriters believe will
not jeopardize the success of the offering by the Parent. If the managing
underwriter or underwriters determine that the inclusion of all or part of the
Parent Shares or Parent ADSs which the Stockholders have requested to be
included would materially adversely affect the success of such offering, then
the Parent shall be required to include in such Incidental Offering, to the
extent of the amount that the managing underwriter or underwriters believe
may be sold without causing such adverse effect, first, all of the
                                                 -----
securities to be offered for the account of the Parent (if any); and
second, the Parent Shares or Parent ADSs to be offered for the account of
------
the Stockholders pursuant to this Section 3.3 and any other securities requested
to be included in such secondary offering, pro rata based on the number of
Parent Shares or Parent ADSs owned by each such stockholder.

(b) The Parent shall bear all expenses in connection with any Incidental
Offering pursuant to this Section 3.3 (except for underwriter commissions or
discounts to be shared on a pro rata basis based on the number of securities
offered by each person).

writing signed on behalf of each of the parties hereto.

A.      Assignment.  Neither this Agreement nor any of the rights, interests or
obligations hereunder shall be assigned by any of the parties hereto, in whole
or in part (whether by operation of law or otherwise), without the prior written
consent of the other party, and any attempt to make any such assignment without
such consent shall be null and void, except that the Parent may assign, in its
sole discretion, any or all of its rights, interests and obligations under this
Agreement to any direct wholly owned Subsidiary of the Parent or the Exchange
Agent without the consent of any Stockholder, but no such assignment shall
relieve the Parent of any of its obligations under this Agreement.  Subject to
the preceding sentence, this Agreement will be binding upon, inure to the
benefit of and be enforceable by the parties and their respective successors and
assigns.  Without limiting the generality of the foregoing, the rights under
Section 4.3 shall not be assignable to any other person, including any purchaser
or other transferee of Parent Shares or Parent ADSs.

A.        Submission to Jurisdiction; Waivers.  Each of the Parent and the
Stockholders irrevocably agrees that any legal action or proceeding with respect
to this Agreement or for recognition and enforcement of any judgment in respect
hereof brought by the other party hereto or its successors or assigns may be
brought and determined in the Chancery or other Courts of the State of Delaware,
and each of the Parent and the Stockholders hereby irrevocably submits with
regard to any such action or proceeding for itself and in respect to its
property, generally and unconditionally, to the nonexclusive jurisdiction of the
aforesaid courts. Each of the Parent and the Stockholders hereby irrevocably
waives, and agrees not to assert, by way of motion, as a defense, counterclaim
or otherwise, in any action or proceeding with respect to this Agreement, (a)
any claim that it is not personally subject to the jurisdiction of the above-
named courts for any reason other than the failure to lawfully serve process,
(b) that it or its property is exempt or immune from jurisdiction of any such
court or from any legal process commenced in such courts (whether through
service of notice, attachment prior to judgment, attachment in aid of execution
of judgment, execution of judgment or otherwise), and (c) to the fullest extent
permitted by applicable law, that (i) the suit, action or proceeding in any such
court is brought in an inconvenient forum, (ii) the venue of such suit, action
or proceeding is improper and (iii) this Agreement, or the subject matter
hereof, may not be enforced in or by such courts.

A.        Specific Performance.  Each of the parties hereto acknowledge that it
will be impossible to measure in money the damage to the other
<PAGE>

parties if a party hereto fails to comply with any of the obligations imposed by
this Agreement, that every such obligation is material and that, in the event of
any such failure, the other parties will not have an adequate remedy at law or
damages. Accordingly, each party hereto agrees that injunctive relief of other
equitable remedy, in addition to remedies at law or damages, is the appropriate
remedy for any such failure and will not oppose the granting of such relief on
the basis that the other parties have an adequate remedy at law. Each party
hereto agrees that it will not seek, and agrees to waive any requirement for,
the securing or posting of a bond in connection with any other party's seeking
or obtaining such equitable relief.

A.        Failure or Indulgence Not Waiver; Remedies Cumulative.  No failure or
delay on the part of any party hereto in the exercise of any right hereunder
will impair such right or be construed to be a waiver of, or acquiescence in,
any breach of any representation, warranty or agreement herein, nor will any
single or partial exercise of any such right preclude other or further exercise
thereof or of any other right. All rights and remedies existing under this
Agreement are cumulative to, and not exclusive to, and not exclusive of, any
rights or remedies otherwise available.

A.        Attorney's Fees.  In any action or proceeding brought to enforce any
provision of this Agreement or where any provision hereof is validly asserted as
a defense, the successful party shall, to the extent permitted by applicable
law, be entitled to recover all attorney's fees in addition to any other
available remedy.

     --------------------------------
agrees not to:

the Company for purposes of such Rules and applying the restrictions of such
Rules to any Transfers outside the United States as well as within (i.e. without
regard to Regulation S);

     (ii) Transfer, in any four calendar week period, (x) Parent ADSs in excess
of one-third the average weekly reported volume of trading in such securities
reported through the Nasdaq Stock Market during the preceding four calendar

<PAGE>

(y) Parent Shares in excess of the greater of (A) one-third the average weekly
reported volume of trading in such securities reported through the Neuer Markt

period not to extend more than two weeks (14 days) prior to the reasonably
expected closing date for such offering or beyond 90 days after the actual
closing of such offering).

(a)  Notwithstanding any restrictions contained in Sections 2.2(a) or 2.2(b)(i)
and (ii) (but not 2.2(b)(iii)), the Majority Shareholder may transfer, subject
to the prior written consent of the Parent, Restricted Parent Securities
pursuant to a limited private placement; provided, that the transferee agrees to
be bound by the terms of this Agreement.

     -------------
certificates representing Restricted Parent Securities of legends reflecting the
restrictions set forth in this Section 2.2.
<PAGE>

A.      Incidental or "Piggy-Back" Offering.

(a)  During the Term of this Agreement, if the Parent proposes to commence an
underwritten public offering of Parent Shares or Parent ADSs in the United
States that is registered with the U.S. Securities and Exchange Commission
(other than on a Form S-8, S-4 or F-4 or successor form) which includes any
Parent Shares or Parent ADSs for the account of one or more securityholders of
the Parent, then the Parent shall give written notice of such proposed offering
to the Majority Stockholder at least twenty (20) days before the anticipated
commencement of such offering, and such notice shall describe the proposed
distribution and offer the Majority Stockholder the opportunity to offer the
number of Parent Shares or Parent ADSs (as the case may be) as the Majority
Stockholder may request (an "Incidental Offering"). The Parent shall use
                             -------------------
commercially reasonable efforts (within twenty (20) days of the notice provided
for in the preceding sentence) to cause the managing underwriter or underwriters
to permit the Majority Stockholder if it has requested in writing to participate
in the Incidental Offering to include its Parent Shares or Parent ADSs (as the
case may be) in such underwritten secondary offering on the same terms and
conditions as the securities of such other participating security holders. The
Parent shall not be required to include any such Parent Shares or Parent ADSs
(as the case may be) in such secondary underwritten offering unless the Majority
Stockholder accepts the terms of the underwritten offering as agreed upon
between the Parent and the managing underwriter or underwriters, and then only
in such quantity as the managing underwriter or underwriters believe will not
jeopardize the success of the offering by the Parent. If the managing
underwriter or underwriters determine that the inclusion of all or part of the
Parent Shares or Parent ADSs which the Majority Stockholder has requested to be
included would materially adversely affect the success of such offering, then
the Parent shall be required to include in such Incidental Offering, to the
extent of the amount that the managing underwriter or underwriters believe may
be sold without causing such adverse effect, first, all of the securities to be
                                             -----
offered for the account of the Parent (if any); and second, the Parent Shares
                                                    ------
(or Parent ADSs) to be offered for the account of the Majority Stockholder
pursuant to this Section 2.3 and any other securities requested to be included
in such secondary offering, pro rata based on the number of Parent Shares (or
Parent ADSs) owned by each such stockholder.

(a)  The Parent shall bear all expenses in connection with any Incidental
Offering pursuant to this Section 2.3 (except for underwriter commissions or
discounts to be shared on a pro rata basis based on the number of securities
offered by each person).

of any nature whatsoever under or by reason of this Agreement.

A. Governing Law. This Agreement shall be governed and construed in accordance
with the laws of the State of Oregon (without giving effect to choice of law
principles thereof).

A. Severability. If any term or other provision of this Agreement is invalid,
illegal or incapable of being enforced by any law or public policy, all other
terms and provisions of this Agreement shall nevertheless remain in full force
and effect so long as the economic or legal substance of the transactions
contemplated hereby is not affected in any manner materially adverse to any
party. Upon such determination that any term or other provision is invalid,
illegal or incapable of being enforced, the parties hereto shall negotiate in
good faith to modify this Agreement so as to effect the original intent of the
parties as closely as possible in an acceptable manner in order that the
transactions contemplated hereby are consummated as originally contemplated to
the greatest extent possible.

A. Amendment. This Agreement may not be amended except by an instrument in
writing signed on behalf of each of the parties hereto.

A. Assignment. Neither this Agreement nor any of the rights, interests or
obligations hereunder shall be assigned by any of the parties hereto, in whole
<PAGE>

or in part (whether by operation of law or otherwise), without the prior written
consent of the other party, and any attempt to make any such assignment without
such consent shall be null and void, except that the Parent may assign, in its
sole discretion, any or all of its rights, interests and obligations under this
Agreement to any direct wholly owned Subsidiary of the Parent or the Exchange
Agent without the consent of the Majority Stockholder, but no such assignment
shall relieve the Parent of any of its obligations under this Agreement. Subject
to the preceding sentence, this Agreement will be binding upon, inure to the
benefit of and be enforceable by the parties and their respective successors and
assigns. Without limiting the generality of the foregoing, the rights under
Section 2.3 shall not be assignable to any other person, including any purchaser
or other transferee of Parent Shares or Parent ADSs.

A. Submission to Jurisdiction; Waivers. Each of the Parent and the Majority
Stockholder irrevocably agrees that any legal action or proceeding with respect
to this Agreement or for recognition and enforcement of any judgment in respect
hereof brought by the other party hereto or its successors or assigns may be
brought and determined in the Courts of the State of Oregon, and each of the
Parent and the Majority Stockholder hereby irrevocably submits with regard to
any such action or proceeding for itself and in respect to its property,
generally and unconditionally, to the nonexclusive jurisdiction of the aforesaid
courts. Each of the Parent and the Majority Stockholder hereby irrevocably
waives, and agrees not to assert, by way of motion, as a defense, counterclaim
or otherwise, in any action or proceeding with respect to this

Agreement, (a) any claim that it is not personally subject to the jurisdiction
of the above-named courts for any reason other than the failure to lawfully
serve process, (b) that it or its property is exempt or immune from jurisdiction
of any such court or from any legal process commenced in such courts (whether
through service of notice, attachment prior to judgment, attachment in aid of
execution of judgment, execution of judgment or otherwise), and (c) to the
fullest extent permitted by applicable law, that (i) the suit, action or
proceeding in any such court is brought in an inconvenient forum, (ii) the venue
of such suit, action or proceeding is improper and (iii) this Agreement, or the
subject matter hereof, may not be enforced in or by such courts.

A. Specific Performance. Each of the parties hereto acknowledge that it will be
impossible to measure in money the damage to the other parties if a party hereto
fails to comply with any of the obligations imposed by this Agreement, that
every such obligation is material and that, in the event of any such failure,
the other parties will not have an adequate remedy at law or damages.
Accordingly, each party hereto agrees that injunctive relief of other equitable
remedy, in addition to remedies at law or damages, is the appropriate remedy for
any such failure and will not oppose the granting of such relief on the basis
that the other parties have an adequate remedy at law. Each party hereto agrees
that it will not seek, and agrees to waive any requirement for, the securing or
posting of a bond in connection with any other party's seeking or obtaining such
equitable relief.

A. Failure or Indulgence Not Waiver; Remedies Cumulative. No failure or delay on
the part of any party hereto in the exercise of any right hereunder will impair
such right or be construed to be a waiver of, or acquiescence in, any breach of
any representation, warranty or agreement herein, nor will any single or partial
exercise of any such right preclude other or further exercise thereof or of any
other right. All rights and remedies existing under this Agreement are
cumulative to, and not exclusive to, and not exclusive of, any rights or
remedies otherwise available.

A. Attorney's Fees. In any action or proceeding brought to enforce any provision
of this Agreement or where any provision hereof is validly asserted as a
defense, the successful party shall, to the extent permitted by applicable law,
be entitled to recover all attorney's fees in addition to any other available
remedy.

person thereunto duly authorized as of the date first written above.
