                          AGREEMENT AND PLAN OF MERGER

         This Agreement and Plan of Merger (as the same may be amended,
supplemented or modified in accordance with the terms hereof, this "Agreement")
dated February 7, 2001 is among Labtec Inc., a Massachusetts corporation
(together with its successor and assigns, the "Company"), for the purposes of
Sections 1.1(b) and 11.7 only, Logitech International S.A., a Swiss corporation
(together with its successor and assigns, "Parent"), Logitech Inc., a California
corporation and a wholly-owned subsidiary of Parent (together with its
successors and assigns, "Logitech Subsidiary"), and Thunder Acquisition Corp., a
Massachusetts corporation and a direct wholly-owned subsidiary of Logitech
Subsidiary (together with its successor and assigns, "Merger Sub").

                                    Recitals
                                    --------

         The parties desire that Logitech Subsidiary acquire the Company, upon
the terms and conditions set forth herein and in accordance with the
Massachusetts Business Corporation Law and Chapter 156B of the Massachusetts
General Laws (collectively, the "MBCL").

         In furtherance of such acquisition, it is proposed that Merger Sub
shall, and Logitech Subsidiary shall cause Merger Sub to, make an exchange offer
(as it may be amended from time-to-time as permitted under this Agreement, the
"Offer") to acquire, upon the terms and subject to the conditions of this
Agreement and the Offer, all of the issued and outstanding shares (each, a
"Share" and collectively, the "Shares") of the Company's common stock, par value
$.01 per share ("Company Common Stock"), at a price for each Share of (i) $11.00
in cash (such price, or such higher price per share in cash that may be made
pursuant to the Offer, is referred to as the "Cash Portion"), and (ii) a
fraction of an American depositary share (each, a "Parent ADS") of Parent equal
to the Stock Portion (as defined in Section 1.1(d) below) (each Parent ADS
representing one-tenth of a registered share, par value CHF 10 per share, of
Parent and evidenced by an American depositary receipt ("Parent ADR") issued in
accordance with the Deposit Agreement dated as of March 27, 1997 among Parent,
The Bank of New York, as depositary, and all owners from time to time of Parent
ADSs, as amended on July 5, 2000 (as so amended, the "Deposit Agreement").

         Also in furtherance of such acquisition, it is proposed that, following
the consummation of the Offer, Merger Sub will merge with and into the Company
(the "Merger") and that the Shares not tendered and accepted pursuant to the
Offer will thereupon be converted into the right to receive both cash and a
fraction of a Parent ADS in the amounts set forth in Section 2.4(c) hereof.

         The respective boards of directors of the Company, Parent, Logitech
Subsidiary and Merger Sub have authorized, adopted and approved this Agreement
and deem this Agreement, the Offer and the Merger desirable and in the best
interests of their respective corporations and stockholders.

         This Agreement and the Merger have been adopted and approved by
Logitech Subsidiary as the sole stockholder of Merger Sub and will be submitted
to the stockholders of the Company for their adoption and approval.


         Concurrently herewith, Logitech Subsidiary and two stockholders of the
Company have entered into a Stockholder Agreement (the "Stockholder Agreement")
in the form attached hereto as Exhibit A, providing that, among other things,
such stockholders will tender their Shares pursuant to the Offer and vote their
Shares and those Shares over which they have voting power in favor of the
adoption and approval of this Agreement, and that the Parent ADSs to be received
by such stockholders shall be subject to a contractual lock-up as provided
therein.

                                    Agreement
                                    ---------

         Logitech Subsidiary, Merger Sub and the Company agree as follows:

                                    Article I
                                    The Offer
                                    ---------

         Section 1.1 The Offer.

         (a) Provided that this Agreement shall not have been terminated and
subject to the provisions of this Agreement and the conditions set forth on
Annex A hereto, as promptly as practicable after the date hereof, but in no
event later than ten business days following the public announcement of the
terms of this Agreement, Merger Sub shall, and Logitech Subsidiary shall cause
Merger Sub to, commence, within the meaning of Rule 14d-2 under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), the Offer. The obligation
of Merger Sub to, and of Logitech Subsidiary to cause Merger Sub to, accept for
payment any Shares tendered in the Offer shall be subject to the satisfaction of
only those conditions set forth on Annex A. The initial expiration date of the
Offer shall be the 20th "business day" (as such term is defined in Rule
14d-1(g)(3) under the Exchange Act) following the commencement of the Offer
(determined using Rules 14d-1(g)(3) and 14d-2 under the Exchange Act). Merger
Sub and Logitech Subsidiary expressly reserve the right to waive any condition
to the Offer or modify the terms of the Offer, except that, without the consent
of the Company, Merger Sub shall not, and Logitech Subsidiary shall not cause
Merger Sub to, (i) reduce the number of shares of Company Common Stock subject
to the Offer, (ii) reduce the Cash Portion or reduce the Stock Portion, (iii)
waive or change the Minimum Condition (as defined in Annex A), (iv) modify in
any manner adverse to the holders of Company Common Stock or add to the
conditions to the obligation of Merger Sub to, or Logitech Subsidiary to cause
Merger Sub to, accept for payment any Shares tendered in the Offer set forth in
Annex A, (v) except as provided in the next two sentences, extend the Offer or
(vi) change the form of consideration payable in the Offer. Notwithstanding the
foregoing, Merger Sub may, and Logitech Subsidiary may cause Merger Sub to,
without the consent of the Company, (x) extend the Offer for any period required
by any rule, regulation, interpretation of the Securities and Exchange
Commission (the "SEC") or the staff thereof; (y) from time to time extend the
Offer, if at the scheduled expiration date of the Offer any of the conditions to
the Offer shall not have been satisfied or waived, until such time as such
conditions are satisfied or waived; or (z) extend the Offer for any reason on
one or more occasions for an aggregate period of not more than 10 business days
beyond the latest expiration date that would otherwise be permitted under clause
(x) or (y) of this sentence if on such expiration date there shall not have been
tendered (and not properly withdrawn) at least 90%

                                      -2-


of the outstanding Shares on a Fully Diluted Basis. Logitech Subsidiary and
Merger Sub agree that, if any one or more of the conditions to the Offer set
forth on Annex A are not satisfied then, provided that such conditions are
reasonably capable of being satisfied, Merger Sub shall, at the request of the
Company, extend the Offer from time to time unless any such condition is no
longer reasonably capable of being satisfied or any such event has occurred;
provided, however, that in no event shall Merger Sub be required to extend the
Offer beyond July 15, 2001. Following expiration of the Offer, Merger Sub may,
and Logitech Subsidiary may cause Merger Sub to, make available a "subsequent
offering period" in accordance with Rule 14d-11 of the Exchange Act. On the
terms and subject to the conditions of the Offer and this Agreement, Merger Sub
shall, and Logitech Subsidiary shall cause Merger Sub to, accept for payment and
pay for all Shares validly tendered and not withdrawn pursuant to the Offer as
soon as practicable after the expiration of the Offer. With respect to any such
Shares the Cash Portion shall be net to the seller thereof in cash, subject to
reduction only for any applicable federal back-up withholding or stock transfer
taxes payable by such seller.

         (b) On the date of commencement of the Offer, Parent shall file with
the SEC a Registration Statement on Form F-4, which will include a preliminary
prospectus containing the information required under Rule 14d-4(b) under the
Exchange Act to register the offer and sale of Registered Parent Shares
represented by Parent ADSs pursuant to the Offer (as the same may be
supplemented or amended, the "Form F-4"). On the date of commencement of the
Offer, Logitech Subsidiary and Merger Sub shall file with the SEC a Tender Offer
Statement on Schedule TO (together with any communications filed with the SEC
under cover of Schedule TO prior to commencement of the Offer in accordance with
Rule 14d-2(b) under the Exchange Act, and as such Schedule TO may be
supplemented or amended, the "Schedule TO") with respect to the Offer, which
shall contain an offer to purchase and a related letter of transmittal and
summary advertisement (such Schedule TO, the Form F-4 and the documents included
therein pursuant to which the Offer will be made, together with any supplements
or amendments thereto, the "Offer Documents"). Each of Logitech Subsidiary,
Merger Sub and the Company shall promptly correct any information provided by it
for use in the Offer Documents if and to the extent that such information shall
have become false or misleading in any material respect, and each of Logitech
Subsidiary and Merger Sub shall, upon becoming aware that such information shall
have become false or misleading in any material respect, take all steps
necessary to amend or supplement the Offer Documents and to cause the Schedule
TO and Form F-4 as so amended or supplemented to be filed with the SEC and for
the other Offer Documents, as so amended or supplemented, to be disseminated to
the Company's stockholders, in each case as and to the extent required by
applicable federal securities laws. Logitech Subsidiary and Merger Sub shall
give the Company and its counsel a reasonable opportunity to review and comment
on the Offer Documents prior to their being filed with the SEC or disseminated
to the stockholders of the Company. Logitech Subsidiary and Merger Sub shall
provide the Company and its counsel in writing with any comments Logitech
Subsidiary or Merger Sub or their counsel may receive from the SEC or its staff
with respect to the Offer Documents promptly after the receipt of such comments
and shall provide the Company and its counsel with a reasonable opportunity to
participate in the response of Logitech Subsidiary and/or Merger Sub to such
comments. Parent shall not issue certificates or scrip representing fractional
Parent ADSs

                                      -3-


pursuant to the Offer. Logitech Subsidiary will pay cash in lieu of fractional
Parent ADSs in accordance with the provision set forth in the last two sentences
of Section 2.4(d) hereof.

         (c) Logitech Subsidiary and Merger Sub shall, and Logitech Subsidiary
shall cause Merger Sub to, provide or cause to be provided to the Exchange Agent
(as defined in Section 2.6 below) on, prior to or promptly after the expiration
of the Offer (and thereafter on a timely basis) Parent ADRs and funds necessary
to make payment for any Shares that Logitech Subsidiary or Merger Sub become
obligated to purchase pursuant to the Offer.

         (d) The "Stock Portion" shall be determined as follows:

                  (i) if the Average Market Price (as defined below) is equal to
         a price that is not more than $31.34 or not less than $25.64, the Stock

         treasury stock and each Share owned by Parent, Logitech Subsidiary,
         Merger Sub or any other subsidiary of Parent immediately prior to the
         Effective Time shall automatically be cancelled, retired and cease to
         exist and no payment shall be made with respect thereto.

                  (ii) Each share of capital stock of Merger Sub outstanding
         immediately prior to the Effective Time shall be converted into and
         become one share of common stock of the Surviving Corporation with the
         same rights, powers and privileges as the shares so converted and shall
         constitute the only outstanding shares of capital stock of the
         Surviving Corporation.

         (b) Except as otherwise provided in Section 2.4(a), or as provided in
Section 2.5 with respect to Shares as to which appraisal rights shall have been
exercised, each Share outstanding immediately prior to the Effective Time shall
be converted into the right to receive (x) the Cash Portion in cash per Share
from the Surviving Corporation, without any interest thereon and (y) a fraction
of a Parent ADS equal to the Stock Portion (the Cash Portion and the Stock
Portion are collectively referred to as the "Merger Consideration"). From and
after the Effective Time, all such Shares shall no longer be outstanding and
shall automatically be cancelled, retired and cease to exist and each holder of
a certificate (a "Certificate") representing any such Shares shall cease to have
any

                                      -8-

         (c) No certificates or scrip representing fractional Parent ADSs shall
be issued upon the surrender for exchange of Certificates pursuant to this
Article II, no dividend or distribution of Parent shall relate to such
fractional interests, and such fractional interests will not entitle the owner
thereof to vote or to any rights of a holder of Parent ADSs. For purposes of
this Section 2.4(d), all fractional Parent ADSs to which a single record holder
would be entitled shall be aggregated and calculations shall be rounded to four
decimal places. Logitech Subsidiary shall pay to each former holder of Company
Common Stock an amount in cash equal to the product obtained by multiplying (x)
the fractional interest to which such former holder (after taking into account
all Shares held at the Effective Time by such holder) would otherwise be
entitled by (y) (i) the Average Market Price if the Average Market Price is not
more than $31.34 or not less than $25.64, (ii) $31.34 if the Average Market
Price is more than $31.34, or (iii) $25.64 if the Average Market Price is less
than $25.64. Logitech Subsidiary will deposit or will cause to be deposited a
sufficient amount of cash with the Exchange Agent to cover the payments required

Common Stock), extraordinary cash dividends, reorganization, recapitalization,
reclassification, combination, exchange of shares or other like change with
respect to the Company Common Stock occurring on or after the date hereof and
prior to the Effective Time. The Stock Portion shall be adjusted appropriately
to reflect the effect of any stock split, reverse stock split, stock dividend
(including any dividend or distribution of securities convertible into Parent
Registered Shares or Parent ADSs), extraordinary cash dividends, reorganization,
recapitalization, reclassification, combination, exchange of shares or other
like change with respect to the Parent Registered Shares or the Parent ADSs

         Section 2.5 Dissenters' Rights.

         (a) Any Shares that are outstanding immediately prior to the Effective

adopt and approve this Agreement and who has properly exercised, preserved and
perfected dissenters' rights with respect to such Shares in accordance with the
MBCL, including Sections 86 through 98 thereof (the "Dissenting Provisions")
and, as of the Effective Time, has neither effectively withdrawn nor lost its
right to exercise such dissenters' rights ("Dissenting Shares"), will not be
converted into or represent a right to receive the Merger Consideration pursuant
to Section 2.4(c), but the holder thereof will be entitled to payment of the
fair value of such Dissenting Shares in accordance with the Dissenting
Provisions.

         (b) If any holder of Shares who demands dissenters' rights with respect
to such holder's Shares under the MBCL effectively withdraws or loses (through
failure to perfect or otherwise) its dissenters' rights, then as of the
Effective Time or the occurrence of such event, whichever later

                                      -9-


occurs, such holder's Shares will automatically be converted into and represent
only the right to receive the Merger Consideration as provided in Section
2.4(c), without interest thereon, upon surrender of the certificate or
certificates formerly representing such Shares.

         (c) The Company will give Logitech Subsidiary (x) prompt notice of any
written intent to demand payment of the fair value of any Shares, withdrawals of
such demands and any other instruments served pursuant to the MBCL received by
the Company and (y) the opportunity to direct all negotiations and proceedings
with respect to dissenters' rights under the MBCL. The Company may not
voluntarily make any payment with respect to any exercise of dissenters' rights
and may not, except with the prior written consent of Logitech Subsidiary,
settle or offer to settle any such dissenters' rights.

         Section 2.6 Exchange of Certificates.

         (a) Prior to the Effective Time, Logitech Subsidiary shall (i)
designate, or shall cause to be designated, a bank or trust company reasonably
acceptable to the Company to act as exchange agent for the payment of the Merger
Consideration (the "Exchange Agent") upon surrender of Certificates, (ii)
deposit, or cause to be deposited, with the Exchange Agent (A) an amount in cash
equal to the product of the Cash Portion and the number of Shares that are
issued and outstanding at the Effective Time and (B) ADRs representing a number
of Parent ADSs equal to the product of the Stock Portion and the number of
Shares outstanding at the Effective Time, and (iii) the cash amount payable in
lieu of fractional Shares in accordance with Section 2.4(d). For purposes of
determining the aggregate Merger Consideration to be so deposited, Parent shall
assume that, other than with respect to stockholders of the Company with respect
to whom the Company has been informed intend to exercise their appraisal rights
(the Company shall give Parent prompt notice of the receipt by the Company of
its receipt of notice of any such intent), Parent shall assume that no
stockholder of the Company shall perfect any right of appraisal of his, her or
its shares. If for any reason the Exchange Fund is inadequate to pay the amounts
to which holders of Shares shall be entitled under this Section 2.6(a), Logitech
Subsidiary shall take all steps necessary to enable or cause the Surviving
Corporation promptly to deposit additional cash with the Exchange Agent
sufficient to make all payments required under this Agreement, and Logitech
Subsidiary and the Surviving Corporation shall in any event be liable for
payment thereof. The Exchange Fund shall not be used for any purpose except as
expressly provided in this Agreement.

         (b) As soon as reasonably practicable after the Effective Time, the
Surviving Corporation shall cause the Exchange Agent to mail to each holder of
record of a Certificate that immediately prior to the Effective Time represented
outstanding Shares whose shares were converted into the right to receive Merger
Consideration pursuant to Section 2.4(c):

                  (i) a letter of transmittal (which shall specify that delivery
         shall be effected, and risk of loss and title to the Certificates held
         by such person shall pass, only upon delivery of the Certificates to
         the Exchange Agent and shall be in customary form and have such other
         provisions as Logitech Subsidiary may reasonably specify); and

                                      -10-


                  (ii) instructions for use in effecting the surrender of the
         Certificates in exchange for the Merger Consideration.

         (c) Upon surrender of a Certificate for cancellation to the Exchange
Agent, together with such letter of transmittal, duly completed and validly
executed, and such other documents as may reasonably be required by the Exchange
Agent, the holder of such Certificate shall be entitled to receive in exchange
therefor an amount equal to the product of the Merger Consideration and the
number of Shares represented by such Certificate, and the Certificate so
surrendered shall forthwith be cancelled. In the event of a transfer of
ownership of Shares that is not registered in the stock transfer books of the
Company, the proper amount of cash and Parent ADSs may be paid in exchange
therefor to a person other than the person in whose name the Certificate so
surrendered is registered if such Certificate shall be properly endorsed or
otherwise be in proper form for transfer and the person requesting such payment
shall pay any transfer or other taxes required by reason of the payment to a
person other than the registered holder of such Certificate the Merger
Consideration or establish to the satisfaction of Logitech Subsidiary that such
tax has been paid or is not applicable. No interest shall be paid or shall
accrue on the cash payable upon surrender of any Certificate.

         Section 2.7 No Further Ownership Rights in Shares The Merger.
Consideration paid upon the surrender of a Certificate in accordance with the
terms of this Article II shall be deemed to have been paid in full satisfaction
of all rights pertaining to the Shares formerly represented by such Certificate.
At the Effective Time the stock transfer books of the Company shall be closed,
and there shall be no further registration of transfers on the stock transfer
books of the Surviving Corporation of the Shares that were outstanding
immediately prior to the Effective Time. If, after the Effective Time,
Certificates are presented to the Surviving Corporation or the Exchange Agent
for transfer or any other reason, they shall be cancelled and exchanged as
provided in this Article II.

         Section 2.8 No Liability. To the fullest extent permitted by applicable
law, none of Parent, Logitech Subsidiary, Merger Sub, the Company or the
Exchange Agent shall be liable to any person in respect of any cash or Parent
ADSs from the Exchange Fund delivered to a public official pursuant to any
applicable abandoned property, escheat or similar law. If any Certificates shall
not have been surrendered prior to six years after the Effective Time (or
immediately prior to such earlier date on which any Merger Consideration would
otherwise escheat to or became the property of any Governmental Entity (as
defined in Section 4.3 below)), any such Merger Consideration in respect thereof
shall, to the fullest extent permitted by applicable law, become the property of
the Surviving Corporation, free and clear of all claims or interests of any
person previously entitled thereto.

         Section 2.9 Lost, Stolen or Destroyed Certificates.  In the event that
any Certificate shall have been lost, stolen or destroyed, the Surviving
Corporation or Exchange Agent shall pay the Merger Consideration in exchange for
such lost, stolen or destroyed Certificate, upon the making of an affidavit of
that fact by the holder thereof in form and substance reasonably satisfactory to
the Surviving Corporation or Exchange Agent, as the case may be; provided,
however, that the Surviving Corporation may, in its discretion and as a
condition precedent to the payment of such Merger Consideration, require the
owner of such lost, stolen or destroyed Certificate to deliver a

                                      -11-


bond in such sum as the Surviving Corporation may reasonably direct as indemnity
against any claim that may be made against the Surviving Corporation or the
Exchange Agent with respect to such Certificate.

         Section 2.10 Withholding Rights Logitech.  Subsidiary shall be entitled
to deduct and withhold from the consideration otherwise payable pursuant to this
Agreement such amounts as Logitech Subsidiary is required to deduct and withhold
with respect to the making of such payment under the Internal Revenue Code of
1986, as amended (the "Code"), or any provision of state, local or foreign tax
law. To the extent that amounts are so withheld by Logitech Subsidiary, such
withheld amounts shall be treated for all purposes of this Agreement as having
been paid to the holder of the Shares in respect of which such deduction and
withholding was made by Logitech Subsidiary.

         Section 2.11 Termination of Exchange Fund; Charges and Expenses.

         (a) Any portion of the Exchange Fund that remains undistributed to the
holders of Shares for six months after the Effective Time shall be returned to
Logitech Subsidiary, upon demand, and any holder of Shares shall look as a
general creditor only to Logitech Subsidiary for payment of such cash and Parent
ADSs to which such holder may be due subject to applicable law.

         (b) The Surviving Corporation shall pay all charges and expenses,
including those of the Exchange Agent, in connection with the exchange of cash

Company shall take all actions necessary to provide that each outstanding
employee and/or director stock option to acquire shares of Company Common Stock
granted under or governed by the Company's Amended and Restated 1997 Stock
Option Plan, the Company's Amended and Restated Director Option Plan and the
Company's Amended and Restated 1993 Option Plan (collectively, the "Company
Option Plans"), whether or not such options are then exercisable and vested
(each such option a "Company Option"), shall, effective as of the consummation
of the Offer or the Effective Time, as the case may be (in accordance with the
terms of the Company Option Plan pursuant to which such Company Options were
granted), (a) become fully exercisable and vested, (b) represent an option
solely to acquire a unit consisting of (i) the Cash Portion and (ii) the Stock
Portion, and (c) have an exercise price per such unit equal to the exercise
price of such Company Option per share of Company Common Stock immediately prior
to the Effective Time. Unless exercised prior thereto, all of the Company
Options shall terminate at the Effective Time.

The Company is a corporation duly organized, validly existing and in good
standing under the laws of the Commonwealth of Massachusetts and has all
corporate power and authority to own its properties and assets and to carry on
its business as presently conducted. The Company is duly qualified to do
business as a foreign corporation and is in good standing in each jurisdiction
where the character of the property owned or leased by it or the nature of its
activities makes such qualification necessary, except where the failure to be so
qualified would not, individually or in the aggregate, have a Material Adverse
Effect.

         (b) The Company has previously furnished to Logitech Subsidiary a
complete and correct copy of its articles of organization and bylaws, each as
amended to date (together, the "Company Charter Documents"). The Company Charter
Documents and the organizational documents of each Company Subsidiary (as
defined in Section 4.6 below) are in full force and effect. The Company is not
in violation of any of the provisions of the Company Charter Documents, and no
Company Subsidiary is in violation of its equivalent organizational documents

corporate action to authorize the execution, delivery and performance by it of
this Agreement and such related documents. This Agreement has been duly executed
and delivered by the Company and, assuming due and valid authorization,
execution and delivery by the other parties hereto, constitutes a valid and
binding obligation of the Company, enforceable against the Company in accordance
with its terms, except as such enforceability may be limited by (a) applicable
bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or
other similar laws and principles now or hereafter in effect, affecting
creditors' rights generally, (b) rules or principles of equity affecting the
enforcement of obligations generally, whether at law, in equity or otherwise, or
(c) the exercise of the discretionary powers of any court or other authority
before which a proceeding may be brought seeking equitable remedies, including
specific performance and injunctive relief.

         Section 4.3 Governmental Authorization. Except as set forth in Schedule
4.3, the execution, delivery and performance by the Company of this Agreement

would not have a Material Adverse Effect. Section

         4.4 Non-Contravention.  The execution, delivery and performance by the
Company of this Agreement and the consummation by the Company of the
transactions contemplated hereby do not and will not, except as set forth in
Schedule 4.4 and assuming compliance with the matters referred to in Section
4.3, (a) contravene or conflict with the articles of organization or bylaws of
the Company or the organizational documents of any Company Subsidiary, (b)
contravene or conflict with, or constitute a violation of, any provision of any
law, regulation, judgment, injunction, order or decree binding upon the Company
or any Company Subsidiary or any of their respective properties or assets, (c)
with or without the giving of notice or passage of time or both, constitute a
breach or default under, or impair the rights of the Company or any Company
Subsidiary under, or give any rights of termination, amendment, acceleration or
cancellation to any third parties under, any agreement, contract or other
instrument binding upon the Company or any Company Subsidiary or any License (as

(d) result in the creation or imposition of any lien (each, a "Lien") on any
asset of the Company or any Company Subsidiary, except with respect to the
foregoing clauses (c) or (d) such contraventions, conflicts, violations,
breaches, defaults or Liens which would not, individually or in the aggregate,

                                      -14-


have a Material Adverse Effect and will not materially impair the ability of the
Company to consummate the transactions contemplated hereby.

consists of 25,000,000 shares of Company Common Stock and 1,000,000 shares of

the Company or (y) the terms of which govern any such options or other rights.

         Section 4.6 Subsidiaries.  Each Company Subsidiary is duly organized,
validly existing and in good standing under the laws of its jurisdiction of
organization and has all power (corporate or other) and authority to own its
properties and assets and to carry on its business as presently conducted. Each
Company Subsidiary is duly qualified to do business and is in good standing in
each jurisdiction where the character of the property owned or leased by it or
the nature of its activities makes such qualification necessary, except where
the failure to be so qualified would not, individually or in the aggregate, have

interests having ordinary voting power to elect a majority of the board of
directors or other persons performing similar functions are directly or
indirectly owned by the Company. Schedule 4.6 sets forth all Company
Subsidiaries and their respective jurisdictions of organization , authorized

                                      -15-

(i) and (ii) being referred to collectively as the "Company Subsidiary
Securities"); and there are no outstanding obligations of the Company or any
Subsidiary to repurchase, redeem or otherwise acquire any outstanding Company
Subsidiary Securities.

         Section 4.7 Public Information.  The Company has made available to
Logitech Subsidiary a true and complete copy of each report, schedule,
registration statement and definitive proxy statement filed by it with the SEC
(as any such documents have since the time of their original filing been
amended, the "Company Filings") since March 31, 1999, which, except as set forth
on Schedule 4.7, are all the documents (other than preliminary material) that it
was required to file with the SEC since such date. As of their respective dates,
the Company Filings did not, and the Company's Quarterly Report on Form 10-Q for
the nine-month period ended December 31, 2000 (the "Third Quarter 10-Q") will
not, contain any untrue statement of a material fact or omit to state any
material fact necessary in order to make the statements made therein, in the
light of the circumstances under which they were made, not misleading. As of
their respective dates, the Company Filings complied, and the Third Quarter 10-Q
will comply, in all material respects, with the applicable requirements of the
Securities Act of 1933 (the "Securities Act") and the Exchange Act and the rules
and regulations promulgated under such statutes. The financial statements
contained in the Company Filings and in the Company's press release dated
January 22, 2001 as released on PR Newswire (the "Third Quarter Release") were
prepared in accordance with generally accepted accounting principles
consistently applied throughout the periods indicated (except as may be
indicated in the notes thereto, or, in the case of unaudited financial
statements, as permitted by Form 10-Q), and fairly present in all material
respects the consolidated financial position of the Company and its consolidated
subsidiaries at said dates and the consolidated results of operations and cash

         with past practice or any amendment or consent with respect to any
         licensing agreement filed or required to be filed by the Company with
         the SEC; or

                                      -17-


                  (viii) any revaluation by the Company of any of its material
         assets, other than in the ordinary course of business.

against, or to the knowledge of the Company, threatened against, the Company or
any Company Subsidiary or any Plan (as defined in Section 4.11 below) or the
assets of any Plan or any of their respective properties before any court or
arbitrator or any Governmental Entity which, if determined or resolved adversely
to the Company or any Company Subsidiary in accordance with the plaintiff's
demands, could reasonably be expected to have a Material Adverse Effect.

         information statements and reports ("Returns") relating to Taxes
         required to be filed by the Company and each Company Subsidiary with
         any Tax authority, except such Returns which are not, individually or
         in the aggregate, material to the Company and its subsidiaries, taken
         as a whole. All such Returns were correct and complete in all material
         respects, and the Company and each Company Subsidiary have paid all
         Taxes shown to be due on such Returns, other than any Taxes being
         contested in good faith through appropriate procedures.

                  (ii) The Company and each Company Subsidiary have withheld

         income Taxes, Taxes pursuant to the Federal Insurance Contribution Act,
         Taxes pursuant to the Federal Unemployment Tax Act and other Taxes
         required to be withheld, except such Taxes with respect the failure to

         Material Adverse Effect.

                  (iii) There is no material Tax nor is there any material Tax
         deficiency outstanding, proposed or assessed against the Company or any

         extension of any period for the assessment or collection of any Tax.

                  (iv) To the knowledge of the Company, no audit or other
         examination of any Return of the Company or any Company Subsidiary by
         any Tax authority is presently in

                                      -18-

                  (v) No adjustment relating to any Returns filed or required to
         be filed by the Company or any Company Subsidiary has been proposed in
         writing, formally or informally, by any Tax authority to the Company or

                  (vi) Neither the Company nor any Company Subsidiary has any
         liability for any material unpaid Taxes (whether or not required to be
         shown on any Return) which has not been accrued for or reserved on the
         Balance Sheet Date in accordance with generally accepted accounting
         principles, consistently applied, whether asserted or unasserted,
         contingent or otherwise, which are, individually or in the aggregate
         material to Company, other than any liability for unpaid Taxes that may
         have accrued since the Balance Sheet Date in connection with the
         operation of the business of Company and its subsidiaries in the
         ordinary course. There are no liens with respect to Taxes on any of the
         assets of the Company or any Company Subsidiary, other than liens that
         would not, individually or in the aggregate, have a Material Adverse
         Effect, or customary liens for current Taxes not yet due and payable
         (vii) There is no contract, agreement, plan or arrangement to which the
         Company or any Company Subsidiary is a party; including but not limited
         to the provisions of this Agreement, that, individually or
         collectively, could give rise to the payment of any amount that would
         not be deductible pursuant to Sections 280G, 404 or 162(m) of the Code.
         There is no contract, agreement, plan or arrangement to which the
         Company or any Company Subsidiary is a party or by which it is bound to
         compensate any individual for excise taxes paid pursuant to Section
         4999 of the Code.

         to or has any obligation under any tax sharing, tax indemnity or tax
         allocation agreement or arrangement.

         constituted either a "distributing corporation" or a "controlled
         corporation" in a distribution of stock qualifying for tax-free
         treatment under Section 355 of the Code (x) since February 7, 1999 or
         (y) in a distribution which could otherwise constitute part of a "plan"
         or "series of related transactions" (within the meaning of Section
         355(e) of the Code) in conjunction with the Merger.

                  (xi) To the knowledge of the Company, the Company and each
         Company Subsidiary is in substantial compliance with the material terms
         and conditions of agreements with any foreign taxing authority to which
         Company or a subsidiary is a party relating to any

                                      -19-


         tax exemption, tax holiday or other reduction of tax and the
         consummation of the Merger will not have an adverse effect on the
         continued validity and effectiveness of such agreements.

         Section 4.11 Employee Benefit Plans; Employee Matters.

         (a) Except as set forth in the Company Filings or on Schedule 4.11(a),
all employee benefit plans that have ever been maintained, contributed to, or
required to be contributed to, by the Company or any Company Subsidiary for the
benefit of employees or former employees of the Company or any Company
Subsidiaries ("Plans") have been administered substantially in accordance with
their respective terms and, to the extent subject to the Employee Retirement
Income Security Act of 1974, as amended, and the rules and regulations
promulgated thereunder ("ERISA") and, to the extent applicable, the Code and all
other applicable laws, and are in material compliance with ERISA, the Code and
all other applicable laws. Each Plan which is an "employee pension benefit plan"
within the meaning of Section 3(2) of ERISA (each, a "Company Pension Plan") and
which is intended to be qualified under Section 401(a) of the Code, has received
a favorable determination letter from the Internal Revenue Service and such
Company Pension Plan has been administered in substantial compliance with Code
Section 401(a). Neither the Company nor any Company Subsidiary has engaged in a
transaction with respect to any Company Pension Plan that would subject the
Company or any of Company Subsidiary to a material tax or material penalty
imposed by either Sections 4975 through 4980 of the Code or Section 502(i) of
ERISA. Each Plan (other than any stock option plan) can be amended, terminated,
or otherwise discontinued after the Effective Time, without material liability
to Parent, the Company or any Company Subsidiary (other than ordinary
administration expenses). There are no audits, inquiries, or proceedings pending
or, to the knowledge of the Company, threatened by the Internal Revenue Service,
Department of Labor, or any other governmental agency or entity with respect to
any Plan. Neither a Plan, nor the Company or any Company Subsidiary has
represented provided, or has any liability to provide retiree health to any
person for any reason, except as required by the Consolidated Omnibus Budget
Reconciliation Act of 1985, as amended.

         (b) No material liability under Subtitles C or D or Title IV of ERISA
has been or is expected to be incurred by the Company or any Company
Subsidiaries with respect to any ongoing, frozen or terminated Company Pension
Plan, currently or formerly maintained, contributed to, or required to be
contributed to by any of them, or the Plans of any person which is considered
one employer with the Company under Section 4001 of ERISA or Section 414 of the
Code. No legal or administrative action has been taken by the Pension Benefit
Guaranty Corporation ("PBGC") to terminate or to appoint a trustee to administer
the Company Pension Plan and no liability to the PBGC under Title IV of ERISA
has been incurred by the Company or any Company Subsidiary that has not been
satisfied in full. Each Company Pension Plan is fully-funded on a termination
basis and no pension Plan has incurred a reportable event within the meaning of
Section 4043 of ERISA and no Company Pension Plan has incurred any event
described in Section 4041, 4062, or 4063 of ERISA.

                                      -20-


         (c) Neither any Company Pension Plan nor any single-employer plan of
the Company or any Company Subsidiaries has incurred an "accumulated funding
deficiency" (whether or not waived) within the meaning of Section 412 of the
Code or Section 302 of ERISA.

         (d) Except to the extent set forth on Schedule 4.11(d) or as may result
from the termination of the 401(k) plan referred to, and as contemplated by,
Section 6.4 below, the execution and delivery of this Agreement does not, and
the performance of the transactions contemplated by this Agreement will not
(either alone or upon the occurrence of any additional or subsequent events),
constitute an event under any of the Plans that will result in any payment
(whether of severance or otherwise), acceleration, forgiveness of indebtedness,
vesting, distribution, increase in benefits or obligation to fund benefits (such
resulting events being collectively referred to as the "ERISA Obligations") with
respect to any employee of the Company or any of its Subsidiaries, which ERISA
Obligations could reasonably be expected to have a Material Adverse Effect.

         (e) (i) Neither the Company nor any Subsidiary is a party to a
collective bargaining agreement or other labor union contract applicable to
individuals employed by the Company or any Subsidiary, (ii) there is no pending
or, to the Company's knowledge, threatened union organizational effort, material
labor dispute, strike or similar work stoppage against the Company or any
Company Subsidiary and (iii) to the Company's knowledge, there is no pending or
threatened charge or complaint against the Company or any Company Subsidiaries
by the National Labor Relations Board or any comparable state agency.

         (f) Each Plan that has been adopted or maintained by the Company or any
Company Subsidiary, whether informally or formally, or with respect to which the
Company or any Company Subsidiary will or may have any liability, for the
benefit of current or former employees who perform services outside the United
States (collectively, the "International Employee Plan") has been established,
maintained and administered in compliance with its terms and conditions and with
the requirements prescribed by any and all statutory or regulatory laws that are
applicable to such International Employee Plan. Furthermore, no International
Employee Plan has unfunded liabilities, that as of the Effective Time, will not
be offset by insurance or fully accrued. Except as required by law, no condition
exists that would prevent the Company or Logitech Subsidiary from terminating or
amending any International Employee Plan at any time for any reason without
liability to Parent, Logitech Subsidiary, the Company or Company Subsidiaries
(other than ordinary administration expenses or routine claims for benefits).

         Section 4.12 Compliance with Laws; Licenses.

         (a) Neither the Company nor any Company Subsidiary is or has been in
violation of any applicable provisions of any laws, statutes, ordinances or
regulations except where such violations would not have a Material Adverse
Effect.

         (b) Each of the Company and the Company Subsidiaries has and is in
compliance with all permits, licenses and authorizations (collectively,
"Licenses") which are necessary for it to conduct

                                      -21-


its business in the manner in which it is presently conducted except where the
failure to have any such permits, licenses and authorizations would not have a
Material Adverse Effect.

         Section 4.13 Environment.

         (a) Neither the Company nor any Company Subsidiary is in conflict with,
or in default or violation of, any Environmental Laws (as defined in Section
4.13(c)(ii) below) or any order, judgment or decree under any Environmental Law,
applicable to the Company or any Company Subsidiary or by which its or any of
their respective properties is bound or affected, except where such conflict,
default or violation does not have a Material Adverse Effect. No investigation
or review by any governmental or regulatory body or authority is pending or, to
the knowledge of the Company, threatened against the Company or the Company
Subsidiaries, nor has any governmental or regulatory body or authority indicated
to Company an intention to conduct the same, other than, in each such case,
those the outcome of which would not, individually or in the aggregate, have a
Material Adverse Effect.

         (b) The Company has not disposed of, released, discharged or emitted
any Hazardous Materials (as defined in Section 4.13(c)(i) below) into the soil
or groundwater at any properties owned or leased at any time by the Company, or,
to the knowledge of the Company, at any other property, or exposed any employee
or other individual to any Hazardous Materials or any workplace or environmental
condition in such a manner as would result in any material liability or clean-up
obligation of any kind or nature to the Company. To the knowledge of the
Company, no Hazardous Materials are present in, on, or under any properties
owned, leased or used at any time by the Company, and no reasonable likelihood
exists that any Hazardous Materials will come to be present in, on, or under any
properties owned, leased or used at any time by the Company, so as to give rise
to any material liability or clean-up obligation under any Environmental Laws.

         (c) Definitions.

                  (i) "Hazardous Material" is any material or substance that is
         prohibited or regulated by any Environmental Law or that has been
         designated by any governmental authority to be radioactive, toxic,
         hazardous or otherwise a danger to health, reproduction or the
         environment.

                  (ii) "Environmental Laws" are all applicable Laws, rules,
         regulations, orders, treaties, statutes, and codes promulgated by any
         governmental authority which prohibit, regulate or control any
         Hazardous Material or any Hazardous Material activity, including,
         without limitation, the Comprehensive Environmental Response,
         Compensation, and Liability Act of 1980, the Resource Recovery and
         Conservation Act of 1976, the Federal Water Pollution Control Act, the
         Clean Air Act, the Hazardous Materials Transportation Act, the Clean
         Water Act, comparable laws, rules, regulations, ordinances, orders,
         treaties, statutes, and codes of other governmental authorities, the
         regulations promulgated pursuant to any of the foregoing, and all
         amendments and modifications of any of the foregoing, all as amended to
         date.

                                      -22-


         Section 4.14 Restrictions on Business Activities.  There is no
agreement, commitment, judgment, injunction, order or decree binding upon the
Company or the Company Subsidiaries or to which the Company or any Company
Subsidiary is a party that has or could reasonably be expected to have the
effect of prohibiting or materially impairing any material business practice of
the Company or any Company Subsidiary, any acquisition of property by the
Company or any Company Subsidiary or the conduct of business by the Company or
any Company Subsidiary as currently conducted.

         Section 4.15 Title to Property.

         (a) Neither Company nor any Company Subsidiary owns any material real
property. The Company and each Company Subsidiary has good and defensible title
to all of their material properties and assets, free and clear of all liens,
charges and encumbrances except liens for taxes not yet due and payable and such
liens or other imperfections of title, if any, as do not materially detract from
the value of or materially interfere with the present use of the property
affected thereby.

         (b) All leases (the "Leases") pursuant to which the Company or any
Company Subsidiary leases from others real or personal property are valid and
effective in accordance with their respective terms, and there is not, under any
of such leases, any existing default or event of default of the Company or any
Company Subsidiary or, to the Company's knowledge, any other party (or any event
which with notice or lapse of time, or both, would constitute a default and in
respect of which Company or such the Company Subsidiary has not taken adequate
steps to prevent such default from occurring), except for any defaults or events
of default that would be reasonably likely to have, individually or in the
aggregate, a Material Adverse Effect.

         (c) Schedule 4.15 sets forth a list of all real property currently
leased by the Company. The Company has provided Logitech Subsidiary with true,
complete and correct copies of each such Lease; no term or condition of any such
Lease has been modified, amended or waived except as shown in such copies; each
such Lease constitutes the entire agreement of the landlord and the tenant
thereunder; and there are no other agreements or arrangements whatsoever
relating to the Company's use or occupancy of any of the premises described in
such Leases. The Company has not transferred or assigned any interest in any
such Lease, nor has the Company subleased or otherwise granted rights of use or
occupancy of any of the premises described therein to any other person or
entity.

         (d) To the knowledge of the Company, the landlord under each Lease has
complied with all of the requirements, conditions, representations, warranties
and covenants of the landlord thereunder, including, without limitation, the
timely completion of construction of the leased premises in a good and
workmanlike manner and otherwise in accordance with the Leases.

         (e) There is not pending or, to the Company's knowledge, threatened
condemnation or similar proceeding affecting any leased property or any portion
thereof.

         Section 4.16 Intellectual Property.

                                      -23-


         (a) The Company and the Company Subsidiaries own, or possess, free and
clear of any material liens, adequate licenses or other valid rights to use
(including the right to sublicense to customers, suppliers, or others as
needed), all of the material Company Intellectual Property (as defined below)
that is used in the conduct of Company's or Company Subsidiaries' businesses.
Schedule 4.16 sets forth a complete list of all registered Company Intellectual
Property. Schedule 4.16 lists all material contracts, licenses and agreements to
which Company or any Company Subsidiary is a party: (i) with respect to Company
Intellectual Property licensed or transferred to any third party (other than
agreements relating to the sale or distribution of the Company's products
entered into in the ordinary course); or (ii) pursuant to which a third party
has licensed or transferred any material intellectual property to Company which
is incorporated in the Company's current products.

         (b) Neither the Company nor any of the Company Subsidiaries has
received from a third party any written notice of infringement or
misappropriation of or conflict with, in any material respects, Company
Intellectual Property. To the knowledge of the Company, the use of such Company
Intellectual Property in connection with the business and operations of the
Company and the Company's Subsidiaries does not infringe, in any material
respects, on the rights of any person or entity. No material claim by any third
party contesting the validity, enforceability, use or ownership of any of the
Company Intellectual Property owned by the Company or any of the Company
Subsidiaries, is currently outstanding or is, to the knowledge of the Company,
threatened. The Company has not received any written notices of any material
infringement or misappropriation by any third party with respect to the Company
Intellectual Property. Neither the Company nor any Company Subsidiary is aware
of any claim by any other person or entity that any of the products, processes
or business methods of the Company or any Company Subsidiary infringe or may
infringe upon any intellectual property rights of any other person or entity.
The Company and each of the Company Subsidiaries have taken reasonable actions
to maintain and protect its Company Intellectual Property, except for those
actions, which the failure to take, individually or in the aggregate, would not
have a Material Adverse Effect.

         (c) As used herein, "Company Intellectual Property" means all
trademarks, trademark registrations, trademark rights and renewals thereof,
trade names, trade name rights, patent, patent rights, patent applications,
industrial models, inventions, designs, utility models, inventor rights,
software, computer programs, computer systems, copyrights, copyright

proprietary rights, used or held for use in connection with the businesses of
the Company and/or the Company Subsidiaries as currently conducted by them,
together with all applications currently pending or in process for any of the
foregoing.

         (d) The Company and each of the Company Subsidiaries has taken
reasonable steps to protect the Company's and the Company Subsidiaries' rights
in the Company's confidential information and trade secrets that it wishes to
protect or any trade secrets or confidential information of third parties
provided to the Company or any Company Subsidiary, and, without limiting the
foregoing, each of the Company and the Company Subsidiaries has and uses
commercially

                                      -24-


reasonable efforts to enforce a policy requiring each employee and contractor to
execute a proprietary information/confidentiality agreement substantially in the
form provided to Logitech Subsidiary and all current and former employees and
contractors of the Company and any Company Subsidiary have executed such an
agreement, except where the failure to do so is not, individually or in the
aggregate, reasonably likely to materially impair the Company's or the Company
Subsidiaries' rights in the Company Intellectual Property.

         Subsidiary and which may not be canceled without penalty upon notice of

         revenues to the Company for the fiscal year ended March 31, 2000 in
         excess of $500,000.

         Neither the Company nor any Company Subsidiary, nor to the Company's
knowledge any other party to a Company Contract (as defined below), is in
material breach, violation or default under, and neither the Company nor any
Company Subsidiary has received written notice that it has materially breached,

Each of Parent and Logitech Subsidiary is duly qualified to do business as a
foreign corporation and is in good standing in each jurisdiction where the

makes such qualification necessary, except where the failure to be so qualified
would not, individually or in the aggregate, have a Material Adverse Effect.

         (b) Logitech Subsidiary has previously furnished to the Company a

Parent is not in violation of any of the provisions of the Parent Charter

reorganization, moratorium, fraudulent conveyance or other similar laws and
principles now or hereafter in effect, affecting creditors' rights generally,
(b) rules or principles of equity affecting the enforcement of obligations
generally, whether at law, in equity or otherwise, or (c) the exercise of the

Sub or any of their respective properties or assets, or any governmental
licenses, authorizations, consents and approvals held by Parent, Logitech
Subsidiary or Merger Sub, (c) with or without the giving of notice or passage of
time or both, constitute a breach or default under any agreement, contract or
other instrument binding upon Parent, Logitech Subsidiary or Merger Sub, or (d)
result in the creation or imposition of any Lien on any asset of Parent,
Logitech Subsidiary or Merger Sub except with respect to the foregoing clauses

the stockholders of the Company in the Offer and the Merger and, when issued and
deposited under the Deposit Agreement in accordance with the terms hereof and
the Deposit Agreement, will be duly and validly issued and fully paid and
nonassessable, and will be sold free and clear of any Lien, and no preemptive
right, co-sale right, registration right, right of first refusal or other
similar right of shareholders exists with respect to any of the Parent
Registered Shares underlying the Parent

                                      -30-


ADSs to be issued in the Offer and the Merger or the issuance and sale thereof,
other than those that have been expressly waived prior to the date hereof.

         (b) All issued and outstanding shares of capital stock of each Parent
Subsidiary have been duly authorized and validly issued and are fully paid and
nonassessable, and were not issued in violation of, or subject to, any
preemptive rights or other rights to subscribe for or purchase securities.
Parent owns all of the capital stock of the Parent Subsidiaries free and clear
of any and all Liens. Except as set forth in Section 5.9(a) or in the Parent
Filings, as of the date hereof, neither Parent nor any Parent Subsidiary has any
outstanding options to purchase, or receive any preemptive rights or other
rights to subscribe for or to purchase, any securities or obligations
convertible into, or any contracts or commitments to issue or sell, shares of
its capital stock or any such options, rights, convertible securities or
obligations.

         Section 5.10 Public Information. Logitech Subsidiary has made available
to the Company a true and complete copy of each report, schedule, registration
statement and definitive proxy statement filed by it with the SEC since March
31, 1999 (as any such documents have since the time of their original filing
been amended, the "Parent Filings"), which are all the documents (other than
preliminary material) that it was required to file with the SEC since such date.
As of their respective dates, the Parent Filings did not contain any untrue
statement of a material fact or omit to state any material fact necessary in
order to make the statements made therein, in the light of the circumstances
under which they were made, not misleading. As of their respective dates, the
Parent Filings complied in all material respects with the applicable
requirements of the Securities Act and the Exchange Act and the rules and
regulations promulgated under such statutes. The financial statements contained
in the Parent Filings were prepared in accordance with generally accepted
accounting principles consistently applied throughout the periods indicated
(except as may be indicated in the notes thereto or, in the case of unaudited
financial statements, as permitted by applicable federal securities laws), and
fairly present in all material respects the consolidated financial position of
the Parent and its consolidated subsidiaries at said dates and the consolidated
results of operations and cash flows of the Parent and its consolidated
subsidiaries for the periods then ended. For purposes of this Agreement, "Parent
Balance Sheet Date" means September 30, 2000.

         Section 5.11 Absence of Certain Changes. Since the Parent Balance Sheet
Date, or as explicitly contemplated by this Agreement, Parent and the Parent
Subsidiaries have conducted their business in the ordinary course consistent
with past practice and there has not been:

         (a) any Material Adverse Effect;

         (b) any declaration, setting aside or payment of any dividend or other
distribution with respect to any shares of capital stock of the Parent, or,
except in connection with the exercise of options pursuant to Parent's stock
option and other compensation plans and arrangements, any repurchase, redemption
or other acquisition by Parent or any Parent Subsidiary of any outstanding
shares of capital stock or other securities of, or other ownership interests in,
Parent or any Parent

                                      -31-


Subsidiary, except open-market acquisitions of Parent ADSs or Parent Registered
Shares by Parent or Logitech Subsidiary; or

         (c) any material change in any method of accounting or accounting
practice by the Parent or any Parent Subsidiary, except for any such material
change required by a concurrent change of generally accepted accounting
principles.

         Section 5.12 Litigation.  Except as set forth in the Parent Filings,
there is no action, suit, investigation or proceeding pending against, or to the
knowledge of Parent, threatened against, Parent or any Parent Subsidiary or any
of their respective properties before any court or arbitrator or any
Governmental Entity which, if determined or resolved adversely to Parent or any
Parent Subsidiary in accordance with the plaintiff's demands, could reasonably
be expected to have a Material Adverse Effect.

         Section 5.13 Compliance with Laws; Licenses.

         (a) Except as set forth in the Parent Filings, neither the Parent nor
any Parent Subsidiary is in violation of any applicable provisions of any laws,
statutes, ordinances or regulations except where such violations would not have
a Material Adverse Effect.

         (b) Each of Parent and Parent Subsidiaries has all permits, licenses
and authorizations which are necessary for it to conduct its business in the
manner in which it is presently conducted except where the failure to have any
such permits, licenses and authorizations would not have a Material Adverse
Effect.

         Section 5.14 Offer Documents.  The Offer Documents, when filed, will
comply as to form in all material respects with the applicable requirements of
the Exchange Act and the Securities Act and the rules and regulations
promulgated under both of them and will not, at the time of the filing thereof,
at the time of any distribution thereof or at the time of the consummation of
the Offer and the Effective Time (as the same may be amended or supplemented
prior to consummation of the Offer or the Effective Time, as applicable),
contain any untrue statement of a material fact or omit to state any material
fact necessary in order to make the statements made therein, in light of the
circumstances in which they were made, not misleading; provided, however, that
the foregoing covenant shall not apply to information with respect to the
Company and the Company Subsidiaries furnished to Logitech Subsidiary in writing
by the Company specifically for use in the Offer Documents. The information
furnished by Logitech Subsidiary or Merger Sub to the Company in writing for use
in the Company Disclosure Documents will not contain, at the time of filing
thereof, any untrue statement of a material fact or omit to state any material
fact necessary in order to make the statements made therein, in light of the
circumstances in which they were made, not misleading.

         (a) The Company and the Company Subsidiaries will immediately cease any
and all existing activities, discussions or negotiations with any parties

Section 6.3(e) below). From and after the date hereof until the earlier to occur
of the termination hereof and the Effective Time, the Company and the Company
Subsidiaries will not, and nor will they authorize or permit any of their
respective officers, directors, employees or any investment banker, attorney or
other advisor or representative retained by any of them to, directly or
indirectly, (i) initiate, solicit or encourage any Acquisition Proposal, (ii)
participate in any discussions or negotiations regarding, or furnish to any
person any information with respect to, or take any other action to facilitate
any inquiries or the making of any proposal that constitutes or may reasonably
be expected to lead to, any Acquisition Proposal, or (iii) agree to or approve
or recommend any Acquisition Proposal. The Company will take all necessary steps
to promptly inform the individuals or entities referred to in the preceding
sentence of the obligations undertaken in this Section 6.3 and to cause them to
comply with such obligations. Without limiting the foregoing, it is understood
that any violation of the restrictions set forth in this Section 6.3 by any
officer, director, affiliate or employee of the Company or any of the Company
Subsidiaries or any investment banker, attorney or other advisor or
representative of the Company or any of the Company Subsidiaries shall be deemed
to be a breach of this Section 6.3 by the Company.

         (b) From and after the date hereof until the earlier to occur of the
termination hereof and the Effective Time, the Company will promptly notify
Logitech Subsidiary after receipt of any Acquisition Proposal or any request for
nonpublic information relating to the Company or any Company Subsidiary by any
person that to the Company's knowledge may be considering making or has made an
Acquisition Proposal and will keep Logitech Subsidiary informed on a current
basis of the status and details of any such Acquisition Proposal or request. In
addition to the foregoing, the Company shall (x) provide Logitech Subsidiary
with notice of any meeting of the Company Board at which the Company Board is
reasonably expected to consider an Acquisition Proposal in the same manner and
at the same time that such notice is provided to the Company Board
(notwithstanding Section 11.2 hereof) and (y) provide Logitech Subsidiary with
notice of any meeting of the Company Board at which the Company Board is
reasonably expected to recommend a Superior

                                      -36-


Proposal to its stockholders in the same manner and at the same time that such
notice is provided to the Company Board (notwithstanding Section 11.2 hereof).

         (c) Nothing contained in this Section 6.3 shall prohibit (i) the
Company from, in response to an unsolicited, bona fide written Acquisition
Proposal that the Company Board (or a duly authorized committee thereof)
concludes in good faith constitutes a Superior Proposal (as defined in Section
6.3(f) below), engaging in discussions or participating in negotiations with,
and furnishing information to, the party making such Acquisition Proposal to the
extent the Company Board (or such committee), after consultation with it legal
counsel, determines in good faith that it is necessary to do so for it to act in
accordance with its fiduciary duties under applicable law or (ii) the Company
Board from taking and disclosing to the Company's stockholders a position with
respect to a tender or exchange offer by a third party required under Rules
14d-9 and 14e-2(a) promulgated under the Exchange Act or from making any
disclosure to the Company's stockholders or otherwise which, in the reasonable
judgment of the Board of Directors after consultation with its legal counsel,
may be required under applicable law, rules or regulations, including, without
limitation, those of any stock exchange. (

         d) In addition to the obligations of the Company set forth in paragraph
(a) of this Section 6.3, prior to the termination hereof, the Company shall as
promptly as practicable, and in any event within one business day after receipt
thereof, advise Logitech Subsidiary orally and in writing of any request for
information which the Company reasonably believes would lead to an Acquisition
Proposal or of any Acquisition Proposal; the material terms and conditions of
such request, Acquisition Proposal or inquiry; and the identity of the person or
group making any such request, Acquisition Proposal or inquiry. The Company will
keep Logitech Subsidiary informed in all material respects of the status and
details (including material amendments or proposed amendments) of any such
request, Acquisition Proposal or inquiry.

         (e) For purposes of this Agreement, "Acquisition Proposal" means, other
than the transactions contemplated by this Agreement, any tender offer or
exchange offer, or any offer or proposal for (i) a merger or other business
combination involving the Company or any Company Subsidiary, or (ii) the
acquisition of 15% or more of the equity interests in, or 15% or more of the
assets of, the Company or any Company Subsidiary.

         (f) For purposes of this Agreement, "Superior Proposal" means an
Acquisition Proposal relating to the acquisition of a majority of the
outstanding voting securities, or all or substantially all of the assets, of the
Company with respect to which (A) if any cash consideration is involved, the
Company Board shall have concluded in good faith (after consultation with
Company's financial advisors) that the acquiring party is reasonably likely to
obtain any necessary financing, and (B) the Company Board shall have concluded
in good faith after consultation with its financial advisors that the
Acquisition Proposal would, if consummated, result in a transaction more
favorable from a financial point of view, to the Company and its stockholders
than the Offer and the Merger.

         Section 6.4 Termination of 401(k) Plan.  Effective as of the day
immediately preceding the Effective Time, the Company and each Company
Subsidiary, as applicable, shall each terminate

                                      -37-


any and all group severance, separation or salary continuation plans, programs
or arrangements and any and all plans intended to include a Code Section 401(k)
arrangement (unless Logitech Subsidiary provides written notice to the Company
that such 401(k) plans shall not be terminated) (collectively, "Company Employee
Plans"). Unless Logitech Subsidiary provides such written notice to the Company,
no later than three business days prior to the Effective Time, the Company shall
provide Logitech Subsidiary with evidence that such Company Employee Plan(s)
have been terminated (effective as of the day immediately preceding the
Effective Time) pursuant to resolutions of the Company's, or the Company's
Subsidiary's, Board of Directors, as applicable. The form and substance of such
resolutions shall be subject to review and approval of Logitech Subsidiary. The
Company also shall take such other actions in furtherance of terminating such
Company Employee Plan(s) as Logitech Subsidiary may reasonably require.

the Company Charter Documents as in effect on the date hereof shall survive the

         purchase of Shares by the Purchaser pursuant to the Offer for the
         purpose of considering and taking action upon this Agreement;

                  (ii) prepare and file with the SEC a post-effective amendment
         to the Form F-4 for the offer and sale of the Parent Registered Shares
         represented by Parent ADSs pursuant to the Merger and in which a proxy
         statement or information statement pursuant to Rule 14c-2 under the
         Exchange Act prepared by the Company and Logitech Subsidiary relating
         to the Special Meeting (as amended or supplemented from time to time,
         the "Proxy Statement"), as applicable, which will be included as a
         prospectus (the "Post-Effective Amendment");

                  (iii) subject to the applicable provisions of this Agreement
         and the fiduciary duties of the Company Board, include in the Proxy
         Statement the recommendation of the Company Board that stockholders of
         the Company vote in favor of the approval of the Merger and the
         adoption of this Agreement; and

                  (iv) use its commercially reasonable efforts to solicit from
         holders of Shares proxies in favor of the Merger and shall take all
         other action reasonably necessary or advisable to secure the approval
         of stockholders required by the MBCL to effect the Merger.

         (b) Logitech Subsidiary agrees that it will vote, or cause to be voted,
all of the Shares then owned by it or any of its other subsidiaries and
affiliates in favor of the approval of the Merger and the adoption of this
Agreement.

         (c) Each of the Company and Logitech Subsidiary shall notify the other
(and their respective counsel) promptly of the receipt of any comments from the
SEC or its staff and of any request by the SEC or its staff for amendments or
supplements to the Post-Effective Amendment or

                                      -40-


the Proxy Statement for additional information and shall supply the other with
copies of all correspondence between it or any of its representatives, on the
one hand, and the SEC or its staff, on the other hand, with respect to the
Post-Effective Amendment or the Proxy Statement. Each of the Company and
Logitech Subsidiary shall use its commercially reasonable efforts to respond as
promptly as practicable to any comments of the SEC with respect thereto. No
filing of, or amendment or supplement to, or correspondence to the SEC or its
staff with respect to, the Post-Effective Amendment or the Proxy Statement will
be made by either party, without providing the other party a reasonable
opportunity to review and comment thereon. Each of the Company and Logitech
Subsidiary shall use its commercially reasonable efforts to have the
Post-Effective Amendment declared effective under the Securities Act as promptly
as practicable after its filing. The Company will use its commercially
reasonable efforts to cause the Proxy Statement to be mailed to holders of the
Company's capital stock as promptly as practicable after the Post-Effective
Amendment is declared effective under the Securities Act. Parent shall also take
any action (other than qualifying to do business in any jurisdiction in which it
is not now so qualified or to file a general consent to service of process)
required to be taken under any applicable state securities laws in connection
with the issuance of Parent ADSs pursuant to the Offer and the Merger, and the
Company shall furnish all information concerning the Company and its
stockholders as may be reasonably requested in connection with any such action
and the preparation, filing and/or distribution of the Proxy Statement. If at
any time prior to the Effective Time any information relating to the Company or
Parent or Logitech Subsidiary or any of their respective affiliates, officers or
directors, should be discovered by the Company or Logitech Subsidiary which
should be set forth in an amendment or supplement to any of the Post-Effective
Amendment or the Proxy Statement, so that any of such documents would not
include a misstatement of a material fact or omit to state any material fact
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, the party which discovers such information
shall promptly notify the other parties hereto, and an appropriate amendment or
supplement describing such information shall be promptly filed with the SEC and,
to the extent required by law, disseminated by the Company to holders of the
Company's capital stock.

         (d) Notwithstanding Section 8.5(a), (b) or (c) hereof, in the event
that Parent, Logitech Subsidiary, Merger Sub or any other subsidiary of Parent
shall acquire at least 90% of the outstanding shares of each class of capital
stock of the Company entitled to vote on the Merger, pursuant to the Offer or
otherwise, the parties hereto agree, at the request of Logitech Subsidiary and
subject to Article 10 hereof, to take all necessary and appropriate action to
cause the Merger to become effective as soon as practicable after such
acquisition, without a meeting of stockholders of the Company, in accordance
with Section 82 of the MBCL.

         Section 8.6 Affiliates of the Company.  The Company has delivered
herewith written agreements substantially in the form attached hereto as Exhibit
B executed by, to the Company's knowledge, all "affiliates" of the Company for
purposes of Rule 145 under the Securities Act ("Rule 145") as of the date
hereof. Promptly following consummation of the Offer, the Company shall use
commercially reasonable efforts to deliver to Logitech Subsidiary a letter
identifying all other persons who, to the Company's knowledge, may, at the time
of the commencement of the Offer and/or the time this Agreement is submitted to
the holders of Shares for approval, be deemed to be

                                      -41-


"affiliates" of the Company for purposes of Rule 145, except to the extent the
Company and Lighting Subsidiary shall otherwise agree that Rule 145 does not
apply to Shares tendered pursuant to the Offer. The Company shall, except to the
extent the Company and Lighting Subsidiary shall otherwise agree that Rule 145
does not apply to Shares tendered pursuant to the Offer, use commercially
reasonable efforts to cause each such other person who is a holder of Shares at
the commencement of the Offer and/or following consummation of the Offer to
deliver to Logitech Subsidiary, prior to the Closing Date, a written agreement
substantially in the form attached hereto as Exhibit B.

         the Merger; and

                  (iv) Merger Sub (or Parent or Logitech Subsidiary) shall have
         purchased Shares pursuant to the Offer.

                                   Termination

         Subsidiary and Merger Sub;

         (b) by either the Company or Logitech Subsidiary as follows:

                  (i) if the Offer shall not have been consummated on or before

         Agreement under this Section 10.1(b)(i) shall not be available to any
         party whose failure to fulfill any obligation under this

                                      -42-


         Agreement shall have been the cause of, or resulted in, the failure of
         Logitech Subsidiary to consummate the Offer;

                  (ii) if the Special Meeting (including as it may be adjourned
         from time to time) shall have concluded without approval by the
         Company's stockholders of the Merger and this Agreement; provided,
         however, that Logitech Subsidiary may not terminate this Agreement
         under this Section 10.1(b)(ii) if the Shares owned by Parent, Logitech
         Subsidiary or Merger Sub or any other subsidiary or affiliate of Parent
         that can be voted by them under applicable law shall not all have been
         voted in favor of the Merger and this Agreement;

                  (iii) if there shall be any applicable law or regulation that
         makes consummation of the Merger illegal or if any Governmental Entity
         shall have issued an order, decree or ruling, or taken any other action
         (which such order, decree, ruling or other action the parties hereto
         shall use their reasonable efforts to lift), in each case permanently
         enjoining, restraining or otherwise prohibiting the Merger and the
         consummation of the transactions contemplated by this Agreement, which
         such order, decree, ruling or other action shall have become final and
         non-appealable; or

                  (iv) if the Average Market Price is less than $18.00;
         provided, however, that the Company or Logitech Subsidiary may exercise
         their right to terminate this Agreement under this Section 10.1(b)(iv)
         only prior to consummation of the Offer.

         (c) by the Company:

         above), when read without any exception or qualification as to
         materiality or Material Adverse Effect, shall not have been true and

         representations and warranties that speak as of a specific date, which
         shall not have been true and correct as of such date, as if made on
         such date), except where the failure to be so true and correct would
         not, individually or in the aggregate, be reasonably likely to have a
         Material Adverse Effect; provided, however, that in no event may the
         Company terminate this Agreement pursuant to this Section 10.1(c)(i)(A)
         with respect to a failure of such representations and warranties to be

         Company terminate this Agreement pursuant to this Section 10.1(c)(i)(B)
         with respect to a failure of such representations and warranties to be

         failure of such representations and warranties to be so true and
         correct that is reasonably capable of cure unless the Company shall
         have given Logitech Subsidiary written notice that such representations
         and warranties shall have failed to be so true and correct and such
         failure is not cured within 20 business days after the giving of such
         notice; or

                  (D) the representations and warranties of Logitech Subsidiary
         and Merger Sub set forth in Section 5.11(a) of this Agreement shall not

         failure of such representations and warranties to be so true and
         correct that is reasonably capable of cure unless the Company shall
         have given Logitech Subsidiary written notice that such representations
         and warranties shall have failed to be so true and correct and such
         failure is not cured within 20 business days after the giving of such

of Logitech Subsidiary and/or Merger Sub under this Agreement, but only if, with
respect to any breach or failure referred to in this Section 10.1(c)(ii) that is
reasonably capable of cure, the Company shall have given Logitech Subsidiary
written notice of any such breach or failure and such breach or failure is not
cured within 20 business days after the giving of such notice; or

                                      -44-

Company or any committee thereof shall have approved or recommended to the
Company's stockholders any Acquisition Proposal, (ii) the Board of Directors of
the Company or any committee thereof shall for any reason have publicly
withdrawn or shall have amended or modified in a manner adverse to Logitech
Subsidiary its recommendation in favor of the Offer, the adoption and approval

Company shall have failed to include the Recommendations in the Offer Documents
or the Schedule 14D-9; (iv) the Company shall have breached the provisions of
Section 6.3 in any material respect; or (v) an Acquisition Proposal shall have
been commenced or otherwise publicly announced by a person unaffiliated with
Logitech Subsidiary, and the Company shall not, within 10 business days after
such commencement or public announcement, publicly recommended to the Company's
stockholders rejection of such Acquisition Proposal, provided, however, that in
no event shall a Triggering Event include a "stop look and listen" communication
of the nature contemplated in Rule 14d-9(f) under the Exchange Act with respect
to an unsolicited tender offer or exchange offer that, if concluded in
accordance with the terms thereof, would constitute or result in an Acquisition
Proposal.

         The party desiring to terminate this Agreement pursuant to this Section
10.1 (other than pursuant to Section 10.1(a) above) shall give notice of such
termination to the other party.

         Section 10.2 Effect of Termination.  If this Agreement is terminated
pursuant to Section 10.1, this Agreement shall become void and have no effect
without any liability or obligation on the part of any party hereto, (a) other
than liabilities and obligations under the Confidentiality Agreement and (b)
except as provided in Section 11.1(b) and Section 11.3 below and except that no
such

                                      -46-


termination shall relieve any party thereto of any liability for damages
resulting from any willful breach by such party of this Agreement.

                                   Article XI
                                  Miscellaneous
                                  -------------

         Section 11.1 Costs and Expenses.  Except as otherwise provided in this
Agreement, all costs and expenses incurred in connection with this Agreement and
the transactions contemplated hereby will be paid by the party incurring such
expenses; provided, however, that Logitech Subsidiary and the Company shall
share equally the costs and expenses (other than legal and accounting fees)
incurred in connection with the filing, printing and mailing of the Offer
Documents and all regulatory filings.

         (b) If Logitech Subsidiary shall have terminated this Agreement
pursuant to Section 10.1(d)(iii), the Company shall promptly, but in any event
no later than one business day after the date of such termination, pay Logitech
Subsidiary a fee equal to $4,500,000 in immediately available funds (the
"Termination Fee"). In addition, if this Agreement is terminated by Logitech
Subsidiary or the Company, as applicable, prior to the Effective Time pursuant
to Section 10.1(b)(i) without any material failure by Logitech Subsidiary to
fulfill any obligation under this Agreement having been the primary cause of the
failure of Logitech Subsidiary to consummate the Offer, and (i) following the
date of this Agreement and prior to the termination of this Agreement, any
Acquisition Proposal shall have been publicly announced or shall have become
publicly known, and (ii) within 12 months following the termination of this
Agreement, either a Company Acquisition (as defined below) is consummated, or
the Company shall enter into an agreement providing for a Company Acquisition,
then the Company shall pay Logitech Subsidiary the Termination Fee promptly and
as a condition to so consummating or entering into a definitive agreement. The
Company acknowledges that the agreements contained in this Section 11.1(b) are
an integral part of the transactions contemplated by this Agreement, and that,
without these agreements, Logitech Subsidiary would not enter into this
Agreement. Accordingly, if the Company fails to pay in a timely manner the
amounts due pursuant to this Section 11.1(b), and, in order to obtain such
payment, Logitech Subsidiary makes a claim that results in a judgment against
the Company, the Company shall pay to Logitech Subsidiary its reasonable costs
and expenses (including reasonable attorneys' fees and expenses) in connection
with such suit, together with interest on the amounts set forth in this Section
11.1(b) at the prime rate Bank of America N. T. and S. A. in effect on the date
such payment was required Logitech Subsidiary to be made. Logitech Subsidiary
agrees that the payment provided for in this Section 11.1(b) shall be the sole
and exclusive remedy of Logitech Subsidiary and Merger Sub upon termination of
this Agreement where such fee has been paid, and such remedies shall be limited
to the sum stipulated in this Section 11.1(b), regardless of the circumstances
giving rise to such termination; provided, however, that nothing herein shall
relieve either party hereto from liability for the willful breach of, or fraud
in connection with, any of its representations, warranties, covenants or
agreements set forth in this Agreement.

         For the purposes of this Agreement, "Company Acquisition" shall mean
any of the following transactions (other than the transactions contemplated by
this Agreement): (i) a sale or other

                                      -47-


disposition by Company of a business or assets representing more than 35% of the
consolidated net revenues, net income or assets of the Company immediately prior
to such sale; (ii) the acquisition by any person or group (including by way of a
tender offer or an exchange offer or issuance by the Company), directly or
indirectly, of beneficial ownership or a right to acquire beneficial ownership
of shares representing more than 35% of any class of equity securities of
Company; or (iii) a merger, consolidation, business combination,
recapitalization, liquidation, dissolution or similar transaction involving the
Company (other than a transactions in which the Company's current stockholders

         Section 11.3 Survival of Representations and Warranties.  The
representations and warranties contained herein and in any certificate or other
writing delivered pursuant hereto shall not survive the Effective Time or the
termination of this Agreement. All covenants and agreements contained herein
which by their terms are to be performed in whole or in part subsequent to the
Effective Time shall survive the Merger in accordance with their terms. Nothing
contained in this Section 11.3 shall relieve any party from liability for any
willful breach of this Agreement.

         Section 11.4 Amendment. Any provision of this Agreement may be amended,
modified, waived or supplemented prior to the Effective Time if, and only if,
such amendment or waiver is in writing and signed, in the case of an amendment,
by the Company, Logitech Subsidiary and Merger Sub or, in the case of a waiver,
by each party against whom the waiver is to be effective; provided, however,
that, after the approval of this Agreement by the stockholders of the Company,
there shall be no such amendment, modification, waiver or supplement that by law
requires further approval by the stockholders of the Company without the further
approval of such stockholders; provided, further, however, that after the
adoption of this Agreement by the stockholders of the Company, no such
amendment, modification, waiver or supplement shall, without the further
approval of such stockholders, (x) reduce the amount, or change the form, of the
Merger Consideration or (y) alter or

                                      -49-


change any of the other terms or conditions of this Agreement if such alteration
would adversely effect the holders of any shares of capital stock of the
Company.

         Section 11.5 No Waiver.  No failure or delay by any party in exercising
any right, power or privilege hereunder shall operate as a waiver thereof nor
shall any single or partial exercise thereof preclude any other or further
exercise thereof or the exercise of any other right, power or privilege. The
rights and remedies herein provided shall be cumulative and not exclusive of any
rights or remedies provided by law.

         Section 11.6 Section Headings.  The section headings contained in this
Agreement are for reference purposes only and shall not affect in any way the
meaning or interpretation of this Agreement.

         Section 11.7 Successors and Assigns; Guarantee of Merger Sub.
Obligations The provisions of this Agreement shall be binding upon and inure to
the benefit of the parties hereto (including, without limitation, Parent) and
their respective successors and assigns; provided, however, that no party may
assign, delegate or otherwise transfer any of its rights or obligations under
this Agreement without the consent of the other parties hereto. Parent hereby
unconditionally guarantees the full and punctual performance by Logitech
Subsidiary and Merger Sub of all of the obligations of Logitech Subsidiary and
Merger Sub or any of their assignees hereunder. The terms and provisions of
Sections 11.2, 11.4 through 11.6 and 11.8 through 11.14 and its obligations set
forth in Section 1.1(b) and the prior two sentences shall apply to Parent as if
such terms and provisions expressly applied to Parent (whether or not such terms
and provisions expressly apply to Parent), and the address for notices to Parent
shall be the same as the address for notices to Lighting Subsidiary set forth in
Section 11.2. In connection with the obligations of Parent under this Section
11.7, Parent hereby waives any and all rights, notices and defenses to which it
otherwise would or may be entitled as a surety or otherwise, under this
Agreement, any other agreement or applicable law.

         Section 11.8 Governing Law.  This Agreement shall be governed by, and
construed and enforced in accordance with, the laws of the State of New York
that apply to agreements made and performed entirely within such state, except
that the MBCL shall apply to matters relating to the internal governance of the
Company and Merger Sub, the laws of Switzerland shall apply to matters relating
to the internal governance of Parent, and the California Corporations Code shall
apply to matters relating to the internal governance of Logitech Subsidiary.

         Section 11.9 Jurisdiction.  Each of the parties hereto hereby
irrevocably consents and submits to the exclusive jurisdiction of the United
States District Court for the Northern District of California in connection with
any dispute arising out of or relating to this Agreement or the transactions
contemplated hereby, waives any objection to venue in such District (unless such
court lacks jurisdiction with respect to such proceeding, in which case, each of
the parties hereto irrevocably consents to the jurisdiction of the courts of the
State of California in connection with such proceeding and waives any objection
to venue in the State of California), and agrees that service of any summons,
complaint, notice or other process relating to such dispute may be effected in
the manner provided by Section 11.2.

                                      -50-


         Section 11.10 Severability.  If any term or other provision of this
Agreement is invalid, illegal or incapable of being enforced by any rule of law,
or public policy, all other conditions 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 herein is not affected in any manner
materially adverse to any party hereto.

         Section 11.11 Parties in Interest. This Agreement shall be binding upon
and inure solely to the benefit of each party hereto, and nothing in this
Agreement, express or implied, is intended to, or shall confer upon, any other
person any right, benefit or remedy of any nature whatsoever under, or by reason
of, this Agreement, including, without limitation, by way of subrogation;
provided, however, that Section 7.2 is intended for the benefit of the
indemnified parties referenced therein and may be enforced by such indemnified
parties.

         Section 11.12 Public Announcements. Logitech Subsidiary and the Company
will consult with each other before issuing any press release or making any
public statement with respect to this Agreement and the transactions
contemplated hereby, and will not issue any such press release or make any such
public statement prior to such consultation, except as may be required by
applicable law, rule or regulation, or as otherwise permitted by this Agreement,
in which case reasonable efforts to consult with the other party will be made
prior to any such release or public statement.

         Section 11.13 Entire Agreement.  This Agreement, including any exhibits
or schedules hereto, and the Confidentiality Agreement constitute the entire
agreement among the parties hereto with respect to the subject matter hereof and
supersede all other prior agreements and understandings, both written and oral,
among the parties with respect to the subject matter of this Agreement.

         Section 11.14 Counterparts; Effectiveness. This Agreement may be signed
in one or more counterparts, each of which shall be an original, with the same
effect as if the signatures thereto and hereto were upon the same instrument.
This Agreement shall become effective when each party hereto shall have received
counterparts hereof signed by all of the other parties hereto.

         taken as a whole, or (iii) seeking to impose material limitations on
         the ability of the Parent, Logitech Subsidiary or Merger Sub

         including, without limitation, the right to vote the Shares purchased
         by it on all matters properly presented to the Company's stockholders;

                  (b) there shall have been (i) entered, enforced or issued by

         by Parent, Logitech Subsidiary or Merger Sub or (ii) any statute, rule,
         regulation, legislation or interpretation enacted, enforced,
         promulgated, amended or issued by any Governmental Entity applicable to
         (A) Parent, Logitech Subsidiary or Merger Sub or the Company, or (B)
         any transaction contemplated by this Agreement, that in either instance

         be so true and correct would not, individually or in the aggregate, be
         reasonably likely to have a Substantial Adverse Effect;

                  (g) the representations and warranties of the Company set
         forth in Section 4.5 of this Agreement shall not (i) have been true and

         under this Agreement;

                  (j) if, after the date of this Agreement, there shall have

modified in accordance with the terms hereof, this "Agreement") is entered into
as of February 7, 2001 between Logitech Inc., a California corporation (together
with its successors and assigns, "Logitech Subsidiary"), and [Sun Multimedia

         Stockholder owns beneficially and of record an aggregate of [1,936,861]
[95,300] shares (the "Initial Stockholder Shares") of common stock, par value
$.01 per share, of Labtec Inc., a Massachusetts corporation (the "Company").

         Logitech Subsidiary, Logitech S.A., a Swiss Corporation ("Parent") and
the direct parent of Logitech Subsidiary, Thunder Acquisition Corp., a
Massachusetts corporation ("Merger Sub"), and the Company are parties to an
Agreement and Plan of Merger entered into as of the date hereof (as the same may
be amended, supplemented or modified in accordance with its terms, the "Merger
Agreement"). Capitalized terms used but not defined herein have the meanings
assigned to them in the Merger Agreement.

         The Merger Agreement provides, among other things, that Logitech
Subsidiary shall make the Offer to purchase each issued and outstanding share of
Common Stock for (i) the Cash Portion in cash per Share, without any interest
thereon and (ii) a fraction of a Parent ADS equal to the Stock Portion (the Cash
Portion and the Stock Portion are collectively referred to as the "Initial
Transaction Consideration"), and that Merger Sub shall thereafter merge with and
into the Company (the "Merger"), upon the terms and subject to the conditions
set forth in the Merger Agreement.

         As a condition to the willingness of Parent, Logitech Subsidiary and
Merger Sub to enter into the Merger Agreement, and as an inducement to them to
do so, the Stockholder has agreed to tender the Stockholder Shares (as defined
in Section 1.1(a)(i) below) pursuant to the Offer, to vote all the Stockholder
Shares, and all other securities of the Company over which the Stockholder has
or controls voting power, in favor of the Merger, and is executing and
delivering herewith a lock-up agreement with respect to the Parent ADSs to be
received by the Stockholder in the Merger in the form attached hereto as Exhibit
A.

                                    Agreement
                                    ---------

         The parties agree as follows:

                                    The Offer

         Section 1.1 Tender of Shares; No Withdrawal.

         (a)  Promptly,  and in no even later than the  fifteenth  business  day
following the  commencement  of the Offer or, if later,  the fifth  business day
following  receipt of the applicable  Offer  Documents,  the  Stockholder  shall
tender to the Exchange Agent:

                  (i) a  letter  of  transmittal  with  respect  to the  Initial
         Stockholder Shares (and any and all non-cash dividends,  distributions,
         rights, other shares of Common Stock of the Company or other securities
         issued or issuable in respect  thereof)  (collectively,  including  the
         Initial  Stockholder  Shares, the "Stockholder  Shares") complying with
         the  terms  of  the  Offer  to  Purchase   (the  "Offer  to  Purchase")
         distributed by Logitech Subsidiary in connection with the Offer;

                  (ii) the certificates representing the Stockholder Shares; and

                  (iii)  all  other  documents  or  instruments  required  to be

         letter of transmittal.

         (b) Prior to the termination of this Agreement,  the Stockholder  shall
not withdraw the tender of the  Stockholder  Shares  effected in accordance with
Section 1.1(a);  provided,  however, that the Stockholder may decline to tender,
or may withdraw, any and all of the Stockholder Shares if, (i) the Company shall
terminate the Merger  Agreement in accordance with its terms or (ii) without the
prior consent of the Stockholder,  Logitech  Subsidiary  amends the Offer to (A)
reduce the Cash Portion or the Stock Portion, (B) reduce the number of shares of
Company  Common  Stock  subject  to  the  Offer,  or  (C)  change  the  form  of
consideration payable in the Offer.

         Section 1.2 No  Purchase.  Logitech  Subsidiary  may allow the Offer to
expire without  accepting for payment or paying for any Stockholder  Shares,  on
the terms and conditions set forth in the Offer to Purchase.  If all Stockholder
Shares validly  tendered and not withdrawn are not accepted for payment and paid
for in  accordance  with the  terms  of the  Offer to  Purchase,  they  shall be
returned to the Stockholder,  whereupon they shall,  prior to the termination of
this Agreement,  continue to be held by the Stockholder subject to the terms and
conditions of this Agreement.

contemplated by the Merger Agreement

The Stockholder shall not commit or agree to take any action inconsistent with
the foregoing.

set forth in Section 2.1 above,  the  Stockholder  hereby  irrevocably  appoints
Logitech Subsidiary, its officers and designees, with full power of substitution
(each of Logitech  Subsidiary,  its officers and designees  and its  substitutes
being  referred  to  herein  as the  "Proxy"),  and each of them as the true and
lawful  attorney  and proxy of the  Stockholder  until the  termination  of this
Agreement,  to  vote  all  Stockholder  Shares  on  matters  as  to  which  such
Stockholder is entitled to vote at a meeting of the  stockholders of the Company
or to which  such  Stockholder  is  entitled  to  express  consent or dissent to
corporate  action in writing without a meeting of  stockholders,  in the Proxy's
absolute,  sole and binding discretion,  on the matters specified in Section 2.1
above.  The  Stockholder  agrees that the Proxy may, prior to the termination of
this Agreement,  in such  Stockholder's name and stead, (i) attend any annual or
special  meeting of the  stockholders  of the Company  and vote all  Stockholder
Shares at any such  annual or special  meeting as to the  matters  specified  in
Section 2.1 above,  and (ii) execute with respect to all Stockholder  Shares any
written  consent to, or dissent from,  corporate  action  respecting  any matter

Stockholder  agrees to  refrain  from,  without  the prior  written  consent  of
Logitech  Subsidiary,  (x) voting the Stockholder  Shares of such Stockholder at
any annual or special  meeting of the  stockholders of the Company in any manner
inconsistent with the terms of this Agreement, (y) executing any written consent
in  lieu  of a  meeting  of the  stockholders  of  the  Company  in  any  manner
inconsistent  with the terms of this  Agreement,  and (z)  granting any proxy or
authorization  to any  person  with  respect  to the  voting of the  Stockholder
Shares,  except pursuant to this Agreement,  or taking any action contrary to or
in any manner  inconsistent  with the terms of this  Agreement.  The Stockholder
agrees that this grant of proxy and  appointment of attorney is irrevocable  and
coupled with an interest and agrees that the person designated as Proxy pursuant
hereto  may at any time name any other  person as its  substituted  Proxy to act
pursuant hereto, either as to a specific matter or as to all matters.

Logitech Inc.
6505 Kaiser Drive
Fremont, California 94555-3615


RE:  Labtec Inc. (the "COMPANY")


Ladies & Gentlemen:

         The undersigned is an owner of record or beneficially of certain shares
of Common Stock of the Company ("COMMON STOCK"). The Company proposes to enter
into an Agreement and Plan of Merger with Logitech International S.A.,
("PARENT"), Logitech Inc., a wholly-owned subsidiary of Parent, and Thunder
Acquisition Corp. (the "MERGER AGREEMENT"). Pursuant to the terms of the Merger
Agreement, Merger Sub will make an exchange offer for all the outstanding shares
of the Company (the "OFFER") and subsequently Merger Sub will be merged with and
into the Company with the Company to be the surviving corporation in the merger
(the "MERGER"). The undersigned acknowledges that the transactions contemplated
by the Merger Agreement will be of significant benefit to the undersigned and
that you are relying on the representations and agreements of the undersigned
contained in this letter in carrying out and entering into the Merger Agreement.

         As a result of the Offer or the Merger, the undersigned will receive
American Depositary Shares (each a "PARENT ADS"), each of which represents
one-tenth of one registered share, par value Chf 10 per share, of Parent (the
"PARENT REGISTERED SHARES").

          In consideration of the foregoing, the undersigned hereby agrees that
from the date hereof, the undersigned will not offer to sell, contract to sell,
or otherwise sell, dispose of, loan, pledge or grant any rights with respect to
(collectively, a "DISPOSITION") any Parent ADSs now owned or hereafter acquired
directly by such person or with respect to which such person has or hereafter
acquires the power of disposition, otherwise than (i) as a distribution to
partners or shareholders of such person, provided that the distributees thereof
agree in writing to be bound by the terms of this restriction, or (ii) with the
prior written consent of Parent. The foregoing restrictions will terminate (i)
with respect to fifty percent (50%) of the number of Parent ADSs received as a
result of the Offer or the Merger on the 60th day after the completion of the
Offer, and (ii) in full 120 days after the Closing of the Offer (the "LOCK-UP
PERIOD"). The foregoing restriction has been expressly agreed to preclude the
holder of the Parent ADSs from engaging in any hedging or other transaction
which is designed to or reasonably expected to lead to or result in a
Disposition of any Parent ADSs during the Lock-Up Period, even if such Parent
ADSs would be disposed of by someone other than such holder. Such prohibited
hedging or other transactions would include, without limitation, any short sale
(whether or not against the box) or any purchase, sale or grant of any right
(including, without limitation, any put or call option)

                                      S-1


with respect to any Parent ADSs or with  respect to any  security  (other than a
broad-based  market  basket or index) that  included,  relates to or derives any
significant  part of its value from Parent ADSs. The undersigned also agrees and
consents to the entry of stop transfer  instructions  with the Parent's transfer
agent and registrar  against the transfer of Parent ADSs held by the undersigned
except in compliance with the foregoing restrictions.

         Notwithstanding the foregoing, (i) the restrictions described above in
this letter agreement shall not apply to any Parent Registered Shares (A) now
owned or hereafter acquired directly by the undersigned (including Parent
Registered Shares received from the Depositary for the Parent ADSs upon
surrender of the American Depositary Receipt(s) representing the Parent ADSs) or
with respect to which the undersigned has or hereafter acquires the power of
disposition, or (B) that the undersigned may distribute to the partners or
shareholders of such person, and (ii) the surrender to the Depositary for the
Parent ADSs of any or all Parent ADSs to be received by the undersigned as a
result of either the Offer or the Merger shall not be considered a "Disposition"
for purposes of this letter agreement.

         Notwithstanding any provision of this Agreement to the contrary, this
Agreement shall terminate upon termination of the Merger Agreement.

                      [The next page is the signature page]


                                      S-2



                  This agreement is irrevocable and will be binding on the
undersigned and the respective successors, heirs, personal representatives, and
assigns of the undersigned. In the event the Offer has not been consummated on
or before July 15, 2001, this Lock-Up Agreement shall be of no further force or
effect.

Logitech International S.A.
6505 Kaiser Drive
Fremont, CA 94555-3615


Ladies and Gentlemen:

         The undersigned has been advised that, as of the date of this letter,
the undersigned may be deemed to be an "affiliate" of Labtec Inc., a
Massachusetts corporation (the "COMPANY"), as the term "affiliate" is defined
for purposes of paragraphs (c) and (d) of Rule 145 of the rules and regulations
(the "RULES AND REGULATIONS") of the Securities and Exchange Commission (the
"SEC") under the Securities Act of 1933, as amended (the "1933 Act"). Pursuant
to the terms of the Agreement and Plan of Merger dated as of February 7, 2001
(the "MERGER AGREEMENT") among the Company, Logitech International S.A., a Swiss
corporation ("PARENT"), Logitech Inc., a California corporation and wholly-owned
subsidiary of Parent and Thunder Acquisition Corp., a Massachusetts corporation
("MERGER SUB"), Merger Sub will make an exchange offer for all the outstanding
shares of the Company (the "OFFER") and subsequently Merger Sub will be merged
with and into the Company with the Company to be the surviving corporation in
the merger (the "MERGER").

         As a result of the Offer or the Merger, the undersigned will receive
American Depository Shares (each a "PARENT ADS") of Parent in exchange for
shares owned by the undersigned of common stock, par value $0.01, of the Company
(the "COMPANY COMMON STOCK"). Each Parent ADS represents one-tenth of one
registered share, par value Chf 10 per share, of Parent (the "PARENT REGISTERED
SHARES", and together with the Parent ADSs, the "PARENT SECURITIES").

         The  undersigned  represents,  warrants and covenants to Parent and the
Company  that, as of the  respective  date the  undersigned  receives any Parent
Securities as a result of either the Offer or the Merger:

         A.  The  undersigned  shall  not  make  any  sale,  transfer  or  other
disposition  of the Parent  Securities in violation of the 1933 Act or the Rules
and Regulations.

         B. The  undersigned  has read this letter and the Merger  Agreement and
discussed,  to the extent the undersigned felt necessary with the  undersigned's
counsel or counsel for the Company, the requirements of such documents and other
applicable  limitations  upon the  undersigned's  ability to sell,  transfer  or
otherwise dispose of Parent Securities.


         C.  The  undersigned  has been  advised  that the  issuance  of  Parent
Securities  to the  undersigned  pursuant  to the  Offer or the  Merger  will be
registered  with the SEC under the 1933 Act on a Registration  Statement on Form
F-4. The undersigned has also been advised that,  because, at the time the Offer
is  made  to the  undersigned  or the  Merger  is  submitted  for a vote  of the
stockholders  of the Company,  the undersigned may be deemed an affiliate of the
Company,  and, if the undersigned is such an affiliate,  the undersigned may not
sell,  transfer  or  otherwise  dispose  of  Parent  Securities  issued  to  the
undersigned  in the Offer or the  Merger  unless  such sale,  transfer  or other
disposition  (i)  has  been  registered  under  the  1933  Act,  (ii) is made in
conformity with Rule 145 promulgated by the SEC under the 1933 Act, (iii) in the
opinion of counsel reasonably acceptable to Parent, or pursuant to a "no action"
letter obtained by the undersigned  from the SEC staff, is otherwise exempt from
registration  under the 1933  Act,  or (iv) with  respect  to Parent  Securities
issued  pursuant to the Offer, to the extent the Company and Logitech Inc. shall
otherwise agree that Rule 145 does not apply to such Parent Securities.

         D. The  undersigned  understands  that Parent is under no obligation to
register the sale, transfer or other disposition of the Parent Securities by the
undersigned  or on the  undersigned's  behalf  under the 1933 Act or to take any
other  action  necessary in order to enable the  undersigned  to make such sale,
transfer  or  other  disposition  in  compliance  with an  exemption  from  such
registration.

         E. The undersigned  also  understands  that there will be placed on the
certificates  for the Parent  Securities  issued to the  undersigned,  or on any
substitutions  therefor,  a legend stating in substance the following  (provided
that,  with respect to Parent  Securities  issued  pursuant to the Offer, to the
extent the Company and Logitech Inc.  shall  otherwise  agree that Rule 145 does
not apply to such Parent  Securities,  such  legend  shall not be placed on such
certificate):

         "THE SECURITIES REPRESENTED BY THIS CERTIFICATE WERE ISSUED
         IN A TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE
         SECURITIES ACT OF 1933 APPLIES. THE SECURITIES REPRESENTED BY
         THIS CERTIFICATE MAY BE SOLD, TRANSFERRED OR OTHERWISE
         DISPOSED OF ONLY IN ACCORDANCE WITH THE TERMS OF A LETTER
         AGREEMENT BETWEEN THE REGISTERED HOLDER HEREOF AND LOGITECH
         INTERNATIONAL S.A., A COPY OF WHICH AGREEMENT IS ON FILE AT
         THE PRINCIPAL OFFICES OF LOGITECH INTERNATIONAL S.A."

         F. The undersigned  also understands  that,  unless the transfer by the
undersigned of the  undersigned's  Parent  Securities have been registered under
the 1933 Act or is a sale made in  conformity  with the  provisions of Rule 145,
Parent reserves the right to put the following legend on the certificates issued
to  the  undersigned's   transferee  (provided  that,  with  respect  to  Parent
Securities  issued pursuant to the Offer, to the extent the Company and Logitech
Inc.  shall  otherwise  agree  that  Rule  145 does  not  apply  to such  Parent
Securities, such legend shall not be placed on such certificate):

         "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
         REGISTERED UNDER THE SECURITIES ACT OF 1933


         AND WERE ACQUIRED FROM A PERSON WHO RECEIVED SUCH SECURITIES
         IN A TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE
         SECURITIES ACT OF 1933 APPLIES. THE SECURITIES HAVE NOT BEEN
         ACQUIRED BY THE HOLDER WITH A VIEW TO, OR FOR RESALE IN
         CONNECTION WITH, ANY DISTRIBUTION THEREOF WITHIN THE MEANING
         OF THE SECURITIES ACT OF 1933 AND MAY NOT BE SOLD,
         TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN
         EFFECTIVE REGISTRATION STATEMENT OR IN ACCORDANCE WITH AN
         EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE
         SECURITIES ACT OF 1933."

         It is understood and agreed that, except as Parent may otherwise agree,
the legends set forth in paragraphs E and F above shall be removed by delivery
of substitute certificates without such legend if (i) the securities represented
thereby have been registered for sale by the undersigned under the 1933 Act or
(ii) Parent has received either an opinion of counsel, which opinion and counsel
shall be reasonably satisfactory to Parent, or a "no-action" letter obtained by
the undersigned from the SEC staff to the effect that the restrictions imposed
by Rule 145 under the 1933 Act no longer apply to the undersigned.

         G. The undersigned further understands and agrees that the
representations, warranties, covenants and agreements of the
undersigned set forth herein are for the benefit of Parent, the
Company and the Surviving Corporation (as defined in the Merger
Agreement) and will be relied upon by such firms and their respective
counsel and accountants.

         H. The undersigned understands and agrees that this letter
agreement shall apply to all Parent Securities that are acquired by
the undersigned in the Offer or the Merger.




         Execution of this letter should not be considered an admission on the
part of the undersigned that the undersigned is an "affiliate" of the Company as
described in the first paragraph of this letter, nor as a waiver of any rights
that the undersigned may have to object to any claim that the undersigned is
such an affiliate on or after the date of this letter.

                                          Very truly yours,
