ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

         On November 6, 1998, Adaptec, Inc. ("Adaptec" or the "Company")
         entered into an agreement with Texas Instruments, Incorporated ("TI"),
         a Delaware Corporation, under which certain assets of the Company's
         high-end Peripheral Technology Solutions ("PTS") business were
         transferred to TI for approximately $8.5 million in cash, including
         sales tax reimbursement of $0.2 million. The Company received cash
         proceeds of approximately $4.5 million upon consummation of the asset
         purchase agreement. The outstanding balance of $4.0 million is due and
         payable in two equal installments scheduled for February and May of
         1999.

         On January 15, 1999, STMicroelectronics, Inc. ("ST"), a Delaware
         corporation, acquired certain assets and obtained certain intellectual
         property rights of the Company's mainstream PTS business for a purchase
         price of approximately $72.1 million in cash, including sales tax
         reimbursement of $0.4 million.

         The substance of the two transactions was the disposal of substantially
         all the assets, rights and business of the PTS business, excluding
         accounts receivable.

ITEM 7.  FINANCIAL STATEMENTS, PRO FORMA FINANCIAL INFORMATION AND EXHIBITS

         (a)      Financial Statements of Business Acquired: Not applicable
         (b)      Pro forma financial information:

INTRODUCTION TO PRO FORMA FINANCIAL INFORMATION (UNAUDITED)

PRO FORMA CONDENSED CONSOLIDATED BALANCE SHEET

The following unaudited Pro Forma Condensed Consolidated Balance Sheet reflects
the historical condensed consolidated balance sheet of Adaptec at December 31,
1998, adjusted to give effect to the PTS disposition as if it had occurred as of
that date.

The unaudited Pro Forma Condensed Consolidated Balance Sheet should be read in
conjunction with the historical consolidated financial statements and notes
thereto and the narrative sections included elsewhere herein. Because the sale
of assets to ST occurred subsequent to January 1, 1999, actual adjustments and
balances will vary from those presented in the Pro Forma Condensed Consolidated
Balance Sheet. However, management believes that any differences between actual
adjustments and pro forma adjustments will not have a material effect on the pro
forma financial statements.

PRO FORMA CONDENSED CONSOLIDATED STATEMENTS OF OPERATIONS

The following unaudited Pro Forma Condensed Consolidated Statements of
Operations for the year ended March 31, 1998 and the nine months ended December
31, 1998 are based upon the historical condensed consolidated statements of
operations of the Company for the respective periods after giving effect to pro
forma adjustments described in the notes thereto as if the PTS disposition had
been consummated on April 1, 1997 and April 1, 1998, respectively.

The unaudited Pro Forma Condensed Consolidated Statements of Operations should
be read in conjunction with the historical consolidated financial statements and
notes thereto of the Company as previously filed in the Company's annual report
on Form 10-K and the narrative sections included elsewhere herein. The Pro Forma
Condensed Consolidated Statements of Operations are not necessarily indicative
of what actual results of operations would have been for the periods had the
transaction occurred on April 1, 1997 and April 1, 1998, respectively, and do
not purport to indicate the results of future operations.

                                   (Unaudited)



The PTS disposition pro forma adjustments have been made to reflect the
following:

     (A)  Consideration of $76.1 million still to be received related to the
          disposition of PTS. Approximately $4.5 million relating to the sale to
          TI was received in November 1998. The remaining $4.0 million which is
          due in two equal installments of $2.0 million was classified in the
          December 31, 1998 balance sheet as part of prepaid expenses and other.
          This amount was reclassified to cash in the pro forma adjustments.

     (B)  Elimination of assets associated with PTS. These assets include
          goodwill of $4.8 million associated with the Analog Devices, Inc.
          acquisition. The goodwill was eliminated as the technology and other
          intangible assets associated with this acquisition was sold to ST.
          The balance of the assets eliminated relate to inventory, equipment
          and other immaterial assets sold in conjunction with the sale of the
          PTS business.

     (C)  Transaction costs associated with the PTS disposition. Transaction
          costs include legal, accounting and consulting costs associated with
          the sale of the PTS business as well as termination costs of employees
          associated with the PTS business.

     (D)  Income taxes payable associated with taxing the anticipated gain at
          45%. The tax rate of 45% is higher than statutory rates due to book
          write-offs which were offset against sale proceeds and are not
          deductible for tax purposes.

     (E)  Anticipated gain on PTS disposition, net of related taxes.

                            ASSET PURCHASE AGREEMENT

        This ASSET PURCHASE AGREEMENT (this "Agreement") is made and entered
into as of November 6, 1998, by and between Texas Instruments Incorporated, a
Delaware corporation ("Purchaser"), and Adaptec, Inc., a Delaware corporation
("Seller").

                                    RECITALS:

        WHEREAS, Seller desires to sell and Purchaser desires to purchase
certain assets of Seller related to the products and products under development
of Seller listed on Schedule 1 hereto (the "Products"), all on the terms and
subject to the conditions set forth in this Agreement.

        NOW, THEREFORE, in consideration of the mutual covenants,
representations, warranties and agreements herein contained, the parties hereto
agree as follows:

                                 I. DEFINITIONS

        1.1 Definitions. As used in this Agreement, unless the context otherwise
requires, capitalized terms shall have the meanings set forth on Exhibit A
hereto.

                             II. PURCHASE OF ASSETS

        2.1 Purchase and Sale of Assets. On the terms and subject to the
conditions hereof, at the Closing (as defined in Section 5.1), Seller will sell,
transfer, convey, assign and deliver, and Purchaser will purchase and accept,
all of Seller's right, title and interest (subject to Section 2.4) in and to the
rights, properties and assets described in this Section 2.1 (collectively, the
"Assets"), free and clear of all Liens except Permitted Liens:

            (a) Product Designs. All right, title and interest of Seller in and
to the Product Designs and the custom analog cells identified on Schedule 2.1(a)
that are used exclusively in the Products;

            (b) Tangible Assets. The tangible personal property assets of Seller
identified on Schedule 2.1(b) hereto (the "Tangible Assets");

            (d) Intangible Assets. The intangible assets, properties and rights
of Seller listed on Schedule 2.1(d) including the Intellectual Property Rights
therein and thereto, all rights to enforce such Intellectual Property Rights,

<PAGE>   5

recovery for past infringement of such Intellectual Property Rights (the
"Intangible Assets"). "Intellectual Property Rights" shall mean all domestic and
foreign letters patent, patents, patent applications, invention disclosures,
copyrights, trade secrets, mask rights, technical knowledge and know-how;

            (e) Contracts. Subject to Section 2.3, all rights and incidents of
interest of Seller in and to (i) all purchase orders for the purchase of the
2399 Product outstanding at the time of Closing and entered into in the ordinary
course of business consistent with past practice and (ii) each other Contract
identified on Schedule 2.1(e) (collectively, the "High-End Contracts");

            (f) Books and Records. All the books and records of Seller which
relate to product engineering, research and development, and manufacture,
marketing and sale of Products, including, without limitation, customer lists,
backlog information, distributor resale data, internal price books, delivery
performance information, and all outstanding Product price quotes, but only to
the extent that such books and records do not also relate to other products or
products under development of Seller; and

            (g) Inventory. Solely with respect to the 2399 Product, the (i)
tested wafers, (ii) assembled untested units and (iii) finished goods inventory
indicated on Schedule 2.1(g) (the "Inventory").

        2.2 Excluded Assets. No rights, properties or assets of Seller shall be
included in the Assets except to the extent expressly referenced in Section 2.1.
The Assets shall in no event include (i) any cash or cash equivalents, accounts
receivable, bank accounts or securities, (ii) any insurance policies of Seller,
(iii) claims for refunds of taxes paid by Seller prior to the Closing Date, (iv)
any assets of, or held by or with respect to, any employee benefit plan (whether
or not governed by ERISA) or any trust, fund or account that is related to any
such employee benefit plan or that is similar in purpose or function thereto,
(v) any Product or Product component inventories (other than as specified in
Section 2.1(g) above), (vi) any title or interest in the name "Adaptec, Inc." or
any of Seller's monograms, logos, trademarks (other than with respect to part
numbers as described on Schedule 2.1(d)), trade names, service marks or any
variations or combinations thereof, (vii) any of the Adaptec Technology, Adaptec
Technology Property, Adaptec Patents or Adaptec Trademarks or (viii) any of the
assets listed on Schedule 2.2.

        2.3 Nonassignable Contracts.

            (a) Nonassignability. To the extent that any High-End Contract to be
assigned pursuant hereto is not capable of being assigned without the consent,
approval or waiver of a third person or entity, nothing in this Agreement will
constitute an assignment or require the assignment thereof except to the extent
provided in this Section 2.3.

            (b) Seller to Use Reasonable Efforts. Notwithstanding anything
contained in this Agreement to the contrary, Seller will not be obligated to
assign to Purchaser any of its rights and obligations in and to any of the
High-End Contracts referred to in Section 2.3(a)



                                       5
<PAGE>   6

without first having obtained all consents, approvals and waivers necessary for
such assignment; provided, however, that Seller shall use reasonable commercial
efforts to obtain all such consents, approvals and waivers prior to and after
the Closing Date (as defined in Section 5.1).

            (c) If Waivers or Consents Cannot Be Obtained. To the extent that
the consents, approvals and waivers referred to in Section 2.3(a) are not
obtained by Seller, Seller shall use reasonable commercial efforts to (a)
provide to Purchaser the financial and business benefits of any High-End
Contract referred to in Section 2.3(a) and (b) and enforce, at the request and
expense of Purchaser, for the account of Purchaser, any rights of Seller arising
from any such High-End Contract (including without limitation the right to elect
to terminate such High-End Contract in accordance with the terms thereof upon
the advice of Purchaser).

            (d) Cooperation of Purchaser. Purchaser agrees to cooperate with
Seller and supply relevant information to Seller or such third person or entity
in order to assist Seller in its obligations under this Section 2.3.
Notwithstanding the foregoing, nothing contained herein shall obligate Seller or
Purchaser to expend or pay any amount to third parties to obtain any consents,
approvals or waivers.

        2.4 Reservation of Rights. (a) Seller hereby reserves for itself, and
Purchaser hereby grants to Seller, (i) the right to use the Assets without
charge by Purchaser (provided, however, that such right shall not be exercisable
in such a manner as to interfere unreasonably with the normal operations and
business of Purchaser), and (ii) an irrevocable, nonexclusive, royalty-free,
worldwide license to the Assets, in each case, for the limited purposes of
making, using and selling current Products (other than the 2399 Product) through
their "end-of-life" during the period from the Closing to March 31, 1999.

            (b) Seller hereby reserves for itself, and Purchaser hereby grants
to Seller, the irrevocable, perpetual, fully-paid and royalty-free, worldwide
right to use and reproduce the custom analog cells identified in Schedule 2.1(a)
for the sole purpose of developing derivative works that are designs and
circuits for semiconductor devices having geometries other than 0.35 micron.
Seller and Purchaser agree that Seller will own all right, title and interest in
and to any and all intellectual property created by or for Seller in the
development of such derivative works, including all rights of ownership therein
and thereto; except that Seller will not have the right to develop, or authorize
third persons to develop, derivative works that are designs or circuits for
semiconductor devices having 0.35 micron geometries. Nothing in this Agreement
is intended to preclude Seller from independently developing analog and other
cells and technology without reference to Assets assigned to Purchaser
hereunder. Purchaser shall otherwise have all right, title and interest
including intellectual property rights (but specifically excluding patents and
related patent rights) in and to the custom analog cells identified in Schedule
2.1(a) having 0.35 micron geometries; and nothing in this Agreement or in the IP
Agreement is intended to preclude Purchaser from developing analog and other
cells with reference to those cells.

                         III. ASSUMPTION OF LIABILITIES



                                       6
<PAGE>   7

        3.1 Assumed Liabilities. As of the Closing, Purchaser will assume and
thereafter, in due course, pay and fully satisfy the following liabilities and
obligations of Seller (the "Assumed Liabilities") and no other liabilities or
obligations:

            (a) all liabilities and obligations for product warranty claims
arising from the 2399 Products produced or sold by Seller prior to Closing, but
not to exceed $20,000 in the aggregate; and

            (b) all liabilities and obligations of Seller under the High-End
Contracts to the extent assigned to Purchaser, or if not so assigned, to the
extent Purchaser has received the financial and business benefits thereof
pursuant to Section 2.3(c), but in any event excluding any obligations arising
from a breach of any High-End Contract prior to Closing.

        3.2 Retained Liabilities. Notwithstanding anything contained in this
Agreement to the contrary, Purchaser does not assume or agree to pay, satisfy,
discharge or perform, and will not be deemed by virtue of the execution and
delivery of this Agreement or any document delivered at the Closing pursuant to
this Agreement, or as a result of the consummation of the transactions
contemplated by this Agreement, to have assumed, or to have agreed to pay,
satisfy, discharge or perform, any liability, obligation or indebtedness of
Seller other than the Assumed Liabilities (such liabilities and obligations
retained by Seller being referred to herein as the "Retained Liabilities").
Without limiting the foregoing, Seller acknowledges and confirms that all
liabilities and obligations for product warranty claims arising from Seller's
manufacture or sale of current Products (other than the product warranty
obligations in respect of the 2399 Products expressly assumed pursuant to
Section 3.1(a)) constitute Retained Liabilities. It is specifically agreed that
Seller shall remain liable for all the Retained Liabilities and Seller agrees to
discharge the Retained Liabilities as and when the same become due and payable
and to promptly discharge any action or claim in respect thereof.

                               IV. PURCHASE PRICE

        4.1 Purchase Price. In consideration of the conveyance to Purchaser of
the Assets and the other rights granted to Purchaser pursuant hereto and subject
to the conditions and in accordance with terms hereof, Purchaser shall (a) pay
to Seller $8,313,403.80, payable in installments on the dates specified below
(the "Purchase Price"), and (b) assume the Assumed Liabilities. At the Closing,
Purchaser will pay $4,313,403.80 of the Purchase Price ($313,403.80 of which is
attributable to the Inventory) to Seller (the "Closing Date Payment") and
Purchaser will assume the Assumed Liabilities. On the date three months after
the Closing Date, Purchaser will pay to Seller an additional $2,000,000 of the
Purchase Price. On the date six months after the Closing Date, Purchaser will
pay to Seller the remaining $2,000,000 of the Purchase Price.

        4.2 Allocation of Purchase Price. Purchaser and Seller agree to consult
with each other with respect to the allocation of the Purchase Price and Assumed
Liabilities to the Assets



                                       7
<PAGE>   8

for tax purposes; provided, however, that nothing contained herein shall be
deemed to obligate either Purchaser or Seller to reach agreement with respect to
such allocation.

        4.3 License Fees and Royalties. In addition to the foregoing, the
Purchaser will pay Seller license fees and royalties in accordance with the
terms of the IP Agreement (the "License Fees and Royalties").

                                   V. CLOSING

                (iii) the IP Agreement, executed by Purchaser;

                (iv) the Sublease Agreement, executed by Purchaser;

                (v) evidence that the party signing on behalf of Purchaser is
authorized to do so; and

                (vi) the amount of $229,899.33, representing the Transaction
Taxes collectible by Seller pursuant to Section 10.15.

            (c) The Bill of Sale, Assignment of Contracts, IP Agreement,
Sublease Agreement and Assumption Agreement shall constitute, collectively, the
"Collateral Agreements."

        5.3 Delivery of Purchased Assets. Title to the Assets passes to
Purchaser as of the Closing at the applicable places of business of Seller.
Promptly following the Closing, Seller will place Purchaser in full possession
and control of the Assets and all other information to be provided in accordance
with the terms of the IP Agreement, provided, however, that Seller need not
deliver the Inventory to be transferred to Purchaser pursuant to Section 2.1(g)
prior to November 7, 1998, and, provided further that, to the extent that the
Inventory actually delivered by Seller differs from the amounts described on
Schedule 2.1(g), Purchaser or Seller, as the case may be, will make a payment to
the other (promptly following such delivery) reflecting the increase or
decrease, respectively, in the amount of Inventory so delivered (with such
payment to be calculated pro rata on the basis of $313,403.80 allocated to the
Inventory described on Schedule 2.1(g)). All information capable of electronic
transmission will be transmitted to Purchaser in such manner. All other assets
and information (other than Assets to remain on the premises of Seller during
the term of the Sublease Agreement) will be delivered by Seller to the business
locations of Purchaser designated by Purchaser by means of delivery reasonably
designated by Purchaser, but at Seller's cost and risk of loss.

                  VI. REPRESENTATIONS AND WARRANTIES OF SELLER

        Seller makes the following representations and warranties to Purchaser,
each of which shall be true and correct (except as set forth in the Disclosure
Schedule attached hereto as Schedule 6) as of the date hereof and shall be
unaffected by any investigation heretofore or hereafter made.

        6.1 Organization and Good Standing. Seller is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware and has the



                                       9
<PAGE>   10

requisite corporate power and authority to own, lease or otherwise hold its
properties and assets and to carry on its business as presently conducted.

        6.2 Authorization and Effect of Agreement. Seller has the requisite
corporate power and authority to execute and to deliver this Agreement and to
perform the transactions contemplated hereby. The execution and delivery by
Seller of this Agreement and the performance by it of the transactions
contemplated hereby have been duly authorized by all necessary corporate action
on the part of Seller. This Agreement has been duly executed and delivered by
Seller and constitutes a valid and binding agreement of Seller, enforceable
against Seller in accordance with its terms, subject to applicable bankruptcy,
reorganization, moratorium, and similar laws affecting creditors' rights and
remedies generally and subject, as to enforceability, to general principles of
equity. Each of the Collateral Agreements, when executed and delivered by Seller
at Closing, will constitute a valid and binding agreement of Seller, enforceable
against Seller in accordance with its terms, subject to applicable bankruptcy,
reorganization, moratorium, and similar laws affecting creditors' rights and
remedies generally and subject, at to enforceability, to general principles of
equity.

        6.3 No Conflicts. The execution and delivery of this Agreement and the
Collateral Agreements by Seller does not, and the performance by Seller of the
transactions contemplated by this Agreement and the Collateral Agreements will
not, (i) give rise to the creation of a Lien upon any of the Assets (other than
in favor of Purchaser or as explicitly contemplated by this Agreement or the
Collateral Agreements), (ii) give rise to a right of termination, cancellation
or acceleration of any material obligation or to a loss of a material benefit
under any of the High-End Contracts, or (iii) conflict with, or result in any
violation of, or constitute a default under or (a) any provision of the
Certificate of Incorporation or Bylaws of Seller, (b) any of the terms,
conditions or provisions of any Contract by which any of the Assets are bound,
or (c) any Law or Order applicable to or binding on Seller or the Assets. Except
as set forth on Schedule 6.3 hereto, no Consent is required to be obtained, made
or given (whether pursuant to applicable Law, Contract or otherwise) in
connection with the execution and delivery of this Agreement by Seller or the
performance by Seller of the transactions contemplated hereby.

        6.4 No Third Party Options. Except as may be set forth in the High-End
Contracts to which Western Digital Corporation is a party, there are no existing
agreements, options or commitments granting to any Person the right to acquire
any of the Assets or any material interest therein.

        6.5 Intellectual Property.

            (a) Ownership. Seller owns or possesses licenses or other rights to
use the Product Designs, the Intangible Assets and the Technology Deliverables
and the Adaptec Technology, Adaptec Technology Property, Adaptec Patents and
Adaptec Trademarks (collectively referred to as "Proprietary Rights") and has
the rights to sell, assign, transfer, license and deliver, as applicable, such
Proprietary Rights to Purchaser as contemplated in this Agreement and the IP
Agreement without any required consent of any third party other than those
identified on Schedule 6.3 hereto, each of which required consents that are also



                                       10
<PAGE>   11
identified on Schedule 5.2(v) has been previously secured. Neither Seller nor
any subsidiary of Seller has granted to any third party any license or other
right to use any of the Proprietary Rights that are to be sold to Purchaser
hereunder. With respect to Proprietary Rights that are to be exclusively
licensed to Purchaser under the IP Agreement, neither Seller nor any subsidiary
of Seller has granted to any third party any license or other right to use such
exclusively licensed Proprietary Rights within Purchaser's Exclusive Field of
Use (as defined in the IP Agreement). Seller has not asserted and does not
assert any trade dress rights with respect to the packaging of any Product.

            (b) No Infringement. Except as set forth on the Disclosure Schedule,
to the knowledge of Seller, the Proprietary Rights do not conflict with or
infringe, and no one has asserted to Seller that such rights conflict with or
infringe, any proprietary rights of any third party. Except as set forth on the
Disclosure Schedule, there are no claims, disputes, actions, proceedings, suits
or appeals pending against Seller with respect to any Proprietary Rights, and to
the knowledge of Seller, none has been threatened against Seller. Except as set
forth on the Disclosure Schedule, to the knowledge of Seller, there are no facts
or alleged facts which would reasonably serve as a basis for any claim that
Seller does not have the right to use, free of any rights or claims of others,
all Proprietary Rights in the design, development, manufacture, use, sale and
other disposition of any or all of the Products.

            (c) Effective Transfer of Rights. Pursuant to this Agreement and the
documents, instruments and agreements contemplated hereby, Seller will, as
applicable, (i) license the Adaptec Technology, Adaptec Technology Property,
Adaptec Patents and Adaptec Trademarks and (ii) transfer good title to the
Product Designs, Intangible Assets and Technology Deliverables to Purchaser.
Schedule 6.5(c) sets forth and summarizes each material Intellectual Property
Right in connection with the development, manufacture, use or sale of the
Products that a third party owns and that Seller uses pursuant to a license,
sublicense, agreement or other permission, except for licenses entered into in
the ordinary course of its business or standard "shrink-wrap" licenses for
off-the-shelf software products.

            (d) No infringement by Third Parties. To Seller's knowledge, the
Proprietary Rights sold to Purchaser hereunder or exclusively licensed to
Purchaser under the IP Agreement are not infringed by any third party, and
Seller has not asserted against any third party that such rights are infringed
by such third party.

        6.6 Litigation. There are no judicial or administrative actions,
proceedings or investigations pending or, to Seller's knowledge, threatened that
question the validity of this Agreement or any action taken or to be taken by
Seller in connection with this Agreement. There are no lawsuits, claims,
administrative or other proceedings or investigations (to which Seller is a
party or is subject) relating to or adversely affecting the Assets pending, or,
to Seller's knowledge, threatened against Seller. There are no judgments, orders
or decrees of any Governmental Authority binding on Seller that relate to or
adversely affect the Assets.

        6.7 Title to and Condition of Assets. Seller has, and at Closing, Seller
will convey to Purchaser, good, valid and indefeasible title to the Assets, free
and clear of all Liens other than Permitted Liens. All of the Tangible Assets
are in good operating condition and repair,



                                       11
<PAGE>   12

subject to normal wear, are usable in the regular and ordinary course of
business and conform to all applicable Laws.

        6.8 Products. (a) Schedule 6.8(a) sets forth, or provides references to,
the terms and conditions of all product warranties and intellectual property
indemnities extended by the Seller to purchasers of the Products during the
preceding three years (or, if shorter, during the period that Seller has sold a
given Product).

            (b) Schedule 6.8(b) sets forth Seller's product warranty, product
return and product liability experience for the Products during the twelve month
period ending September 30, 1998 (or, if shorter, during the period that Seller
has sold a given Product).

            (c) The 2399 Product finished goods inventory set forth on Schedule
2.1(g) hereto is free of defects in material and workmanship and meets all
applicable customer specifications. The 2399 Product tested wafer and assembled
untested units inventory set forth on Schedule 2.1(g) hereto is of a quality and
condition usable in the ordinary course of business, provided, however, that
Seller represents and warrants, as to the usable yield with respect to such
inventories, only that Seller has no reason to believe that such usable yields
will differ materially from the usable yields previously experienced by Seller
for such 2399 Product.

        6.9 Contracts. Seller has provided Purchaser with a complete copy of
each of the High-End Contracts. To Sellers knowledge, the High-End Contracts are
valid and enforceable in accordance with their terms. Seller is not, and to
Seller's knowledge, no other party thereto is, in material default in the
performance, observance or fulfillment of any obligation under the High-End
Contracts, and no event has occurred which with or without the giving of notice
or lapse of time, or both, would constitute a material default thereunder.
Except as listed on Schedule 6.3 hereto, none of the High-End Contracts requires
the consent of any party to its assignment in connection with the transactions
contemplated hereby.

        6.10 Customers. Schedule 6.10 hereto set forth a list of each purchaser
of Products during the twelve months ending September 30, 1998, showing the
approximate total sales (expressed in dollars), by Product, to each such
customer during the twelve months ending September 30, 1998.

        6.11 Year 2000 Compliance. The Products are not Date-Sensitive Systems.
For purposes of this Agreement "Date-Sensitive System" means any software,
microcode, or hardware system or component, including any electronic or
electronically controlled system or component, that processes any data that
includes date information or which is otherwise derived from, dependent on or
related to date information.

        6.12 Disclosure. The representations and warranties of Seller contained
herein, and the statements of Seller contained in any document or other
instrument to be furnished by Seller to Purchaser in connection with the
transactions contemplated hereby, when taken together, do not contain any untrue
statement of a material fact or omit to state a material fact 


                                       12
<PAGE>   13
necessary to make the representations, warranties and statements so made, in
the light of the circumstances under which they were made, not misleading.

                VII. REPRESENTATIONS AND WARRANTIES OF PURCHASER

        Purchaser hereby makes the following representations and warranties to
Seller, each of which shall be true and correct as of the date hereof and shall
be unaffected by any investigation heretofore or hereafter made.

        7.1 Corporate Organization. Purchaser is a corporation duly organized,
validly existing and in good standing under the laws of the State of Delaware
and has the requisite corporate power and authority to own, lease or otherwise
hold its properties and assets and to carry on its business as presently
conducted.

        7.2 Authorization and Effect of Agreement. Purchaser has the requisite
corporate power and authority to execute and deliver this Agreement and to
perform the transactions contemplated hereby. The execution and delivery by
Purchaser of this Agreement and the performance by it of the transactions
contemplated hereby have been duly authorized by all necessary corporate action
on the part of Purchaser. This Agreement has been duly executed and delivered by
Purchaser and constitutes a valid and binding agreement of Purchaser,
enforceable against Purchaser in accordance with its terms, subject to
applicable bankruptcy, reorganization, moratorium and similar laws affecting
creditors' rights and remedies generally and subject, as to enforceability, to
general principles of equity. Each of the Collateral Agreements, when executed
and delivered by Purchaser at Closing, will constitute a valid and binding
agreement of Purchaser, enforceable against Purchaser in accordance with its
terms, subject to applicable bankruptcy, reorganization, moratorium, and similar
laws affecting creditors' rights and remedies generally and subject, as to
enforceability, to general principles of equity.

        7.3 No Conflicts. The execution and delivery of this Agreement and the
Collateral Agreements by Purchaser does not, and the performance by Purchaser of
the transactions contemplated by this Agreement and the Collateral Agreements
will not, conflict with, or result in any violation of, or constitute a default
under (a) any provision of the Certificate of Incorporation or Bylaws of
Purchaser, (b) any of the terms, conditions, or provisions of any agreement or
other document by which Purchaser is bound, or (c) any Law or Order applicable
to or binding on Purchaser. No Consent is required to be obtained, made or given
(whether pursuant to applicable Law, Contract or otherwise) in connection with
the execution and delivery of this Agreement by Purchaser or the performance by
Purchaser of the transactions contemplated hereby.

        7.4 Litigation. There are no judicial or administrative actions,
proceedings or investigations pending or, to Purchaser's knowledge, threatened
that question the validity of this Agreement or any action taken or to be taken
by Purchaser in connection with this Agreement.



                                       13

                                 VIII. COVENANTS

        8.1 Covenant Not to Compete. (a) Seller agrees that prior to the second
anniversary of the Closing Date, neither Seller nor any entity that is
majority-owned or controlled by Seller will own a 20% or greater equity interest
in, or manage, operate, control or participate in the management, operation or
control of, any business, whether in corporate, proprietorship or partnership
form or otherwise, engaged in the design, development, manufacturing, marketing
or sale of products or components for High-End Applications, provided, however,
that Seller will otherwise retain all rights to design, develop, manufacture,
market, sell, license, lease or otherwise exploit all of the Adaptec Technology,
Adaptec Technology Property, Adaptec Patents and Adaptec Trademarks (subject to
the exclusive licenses granted with respect to portions of the Adaptec
Technology Property in the IP Agreement).

            (b) Notwithstanding the foregoing, Seller may, (A) exercise its
rights under Section 2.4 to make, use and sell the current Products (other than
the 2399 Product) through their "end-of-life", and (B) in connection with the
sale and/or license of all or substantially all of the remaining assets in its
peripheral technology solutions business unit, receive, own, and exercise all
rights pursuant to, any minority (20% or less) equity interest in a purchaser or
licensor of such technology and/or business. In no event shall any of (i) such
ownership, (ii) the exercise of any rights pursuant to such ownership, or (iii)
any subleases or short-term (one year or less) manufacturing, supply or other
commercial agreements entered into and performed by Seller and such purchaser or
licensor in connection with, and related to the assets or business that are the
subject of, such sale and/or license, constitute a violation of Section 8.1(a),
regardless of the business activities of such purchaser or licensor.

        8.2 Confidentiality. (a) Seller and Purchaser agree that from and after
the Closing, Seller and Purchaser will continue to be bound by the terms of that
certain undated Master Mutual Nondisclosure Agreement between the parties signed
on or about September 14, 1998 (the "NDA"), provided however, that any
confidential information sold by Seller to Purchaser hereunder or disclosed in
connection with, or pursuant to, this Agreement or the IP Agreement, shall be
subject to the terms of Section 8.2(b) of this Agreement in lieu of being
subject to the NDA.

            (b) Each party agrees that (i) it will not use any Confidential
Information of the other party except as expressly permitted under this
Agreement or the IP Agreement, and (ii) it will maintain all Confidential
Information of the other party in strict confidence and will not disclose the
other party's Confidential Information to any third parties except to employees
and consultants with a bona fide need to know, provided that each such employee
and consultant is subject to written nondisclosure and limited use restrictions
at least as protective as those set forth herein. Each party will use its best
efforts to prevent inadvertent disclosure, publication or dissemination of any
of the other party's Confidential Information and will promptly notify the other
party in writing of any actual or suspected unauthorized use or disclosure of
its Confidential Information. For purposes of this Section 8.2, "Confidential
Information" shall mean any confidential information sold by Seller to Purchaser
hereunder or disclosed in connection with, or pursuant to, this Agreement or the
IP Agreement, including, without



                                       14
<PAGE>   15

limitation, methods of operation, customers, and customer lists, products,
proposed products, former products, prices, fees, costs, plans, designs,
technology, inventions, trade secrets, know-how, software, marketing methods,
policies, plans, personnel, suppliers, competitors, markets or other specialized
information or proprietary matters. The term Confidential Information does not
include, and there shall be no obligation hereunder with respect to, information
that (i) is generally available to the public on the date of this Agreement,
(ii) becomes generally available to the public through no fault or breach of the
receiving party, (iii) is independently developed by the receiving party without
use of or reference to any Confidential Information of the disclosing party, as
established by documentary evidence or (iv) the receiving party rightfully
obtains from other sources without restriction on use or disclosure (where such
sources have not violated any confidentiality obligations to the disclosing
party). A party shall not have any obligation to keep confidential any
Confidential Information of the other party if and to the extent disclosure
thereof is specifically required by Law; provided, however, that in the event
disclosure is required by applicable Law, such party shall, to the extent
reasonably possible, provide such other party with prompt notice of such
requirement prior to making any disclosure so that such other party may seek an
appropriate protective order.

        8.3 Specific Performance. The parties hereto specifically acknowledge
and agree that the remedy at law for any breach of Section 8.1 or 8.2 will be
inadequate and that Purchaser, in addition to any other relief available to it,
shall be entitled to temporary and permanent injunctive relief without the
necessity of proving actual damage.

        8.4 Product Warranty Matters. Seller acknowledges that it has retained
liability for certain Product warranty claims pursuant to Section 3.2. Purchaser
will address and remedy all product warranty claims asserted following the
Closing Date with respect to the 2399 Products produced or sold by Seller prior
to Closing. Subject to the limitations in Section 9.2, Seller will reimburse
Purchaser for all costs and expenses in excess of $20,000 in the aggregate
incurred in remedying such product warranty claims. All such sums shall be
payable within 30 days following receipt of Purchaser's invoice and shall
thereafter bear interest at ten percent per annum until paid. For a period of
two years following the Closing, Purchaser will provide all technical and
manufacturing support to Seller (the "Support") reasonably requested by Seller
in connection with both (i) Seller's exercise of its rights under Section 2.4 to
make, use and sell the current Products (other than the 2399 Product) through
their "end-of-life" and (ii) addressing and remedying all product warranty
claims asserted with respect to all Products produced or sold by Seller (other
than the 2399 Products). Purchaser will record all of its out-of-pocket expenses
incurred by Purchaser directly attributable to providing the Support and the
time spent by its technical personnel providing the Support at a rate of $100
per hour (the "Recorded Expenses"). The Support will be provided by Purchaser
free of any charge to Seller provided that the Recorded Expenses for the first
three-month period following the Closing, the second three-month period
following the Closing, and each subsequent three month period, do not exceed,
$15,000, $10,000 and $5,000, respectively. In the event that the Recorded
Expenses with respect to a given three-month period exceed the applicable limit
in the preceding sentence, then Seller will pay to Purchaser the full amount of
the Recorded Expenses for that three-month period only.



                                       15
<PAGE>   16

        8.5 Maintenance of Books and Records. (a) Each of Seller and Purchaser
shall preserve until the seventh anniversary of the Closing Date all records
possessed by such party relating to the Assets. After the Closing Date, if it is
reasonably necessary that any party hereto or any successors be furnished with
additional information relating to the Assets in order properly to prepare
documents required to be filed with a Governmental Authority (including Tax
authorities) or such party's financial statements, then the other party shall
provide such party with reasonable access, upon prior reasonable written request
specifying the need therefor, during regular business hours, to (i) the relevant
employees of such other party and (ii) the books of account and records of such
other party, but, in each case, only to the extent relating to the Assets, and
such party and its representatives shall have the right to make copies of such
books and records; provided, however, that the foregoing right of access shall
not be exercisable in such a manner as to interfere unreasonably with the normal
operations and business of such other party.

            (b) After the Closing Date, upon the request of Purchaser, Seller
will promptly provide Purchaser with a copy of any records possessed by Seller
as of this date which are material to the commercialization of the Products by
Purchaser. After the Closing Date, to the extent that it is reasonably necessary
in order to prepare documents to be filed with the PTO (i) with respect to the
patents (including those identified as "in process") listed on Schedule 2.1(d),
Seller shall provide Purchaser with reasonable access to the inventors of the
subject of such patents provided that such inventors remain in the employ of
Seller, and (ii) with respect to the patents (including those identified as "in
process") licensed to Purchaser under the IP Agreement, Purchaser shall provide
Seller with reasonable access to the inventors of the subject of such patents to
the extent that such inventors are hereafter employed by Purchaser.

            (c) To the extent that the information disclosed pursuant to this
Section 8.5 constitutes the Confidential Information of such other party, the
requesting party shall be bound by the terms of Section 8.2 with respect to such
Confidential Information.

            (d) Records described in this Section 8.5 may nevertheless be
destroyed by a party if such party sends the other party written notice of its
intent to destroy records, specifying with particularity the contents of the
records to be destroyed. Such records may then be destroyed after the 30th day
following delivery of such notice unless the other party objects to the
destruction, in which case the party seeking to destroy the records shall either
agree to retain such records or to deliver such records to the objecting party.

        8.6 Manufacturing Support. From the date of the Closing through November
6, 1998, Seller will make appropriate technical personnel available to provide a
reasonable level of training and manufacturing support to Purchaser in
connection with the transition of the manufacturing of the 2399 Product without
charge. Further, Seller will notify TSMC that it may sell Purchaser time on
SC212 testers (owned by Seller and located at TSMC) for a period of 6 months
following the Closing (the "Transition Period"). The parties agree and
acknowledge that Purchaser will negotiate with TSMC regarding the cost of such
use and Seller will separately negotiate with TSMC regarding compensation to be
received by Seller from TSMC with respect to such use, provided, however, that
Seller will use all commercially



                                       16
<PAGE>   17

reasonable efforts to ensure that Purchaser is allocated the equivalent of
full-time use of one SC212 tester during the Transition Period.

        8.7 Miscellaneous Employee Matters. (a) To the fullest extent permitted
by Law, Seller will assign to Purchaser (as its successor in interest), and
Purchaser will accept, any and all of Seller's rights, privileges, entitlements
and obligations in and to the existing immigration petitions and/or labor
certification applications filed on behalf of Sushio Verghese and Xin Wang.

            (b) Purchaser and Seller reaffirm their respective obligations under
that certain letter agreement between Purchaser and Seller dated October 1,
1998.

                        IX. SURVIVAL AND INDEMNIFICATION

        9.1 Survival of Representations, Warranties and Covenants. (a) The
representations and warranties of Seller and Purchaser contained in this
Agreement shall survive the Closing until the expiration of two years from the
Closing Date. Any claim for an Indemnifiable Loss (as defined in Section 9.2)
asserted within such period of survival as herein provided will be timely made
for purposes hereof. Notwithstanding anything herein to the contrary, no claim
for indemnification under this Agreement may be brought after the one year
anniversary of the Closing Date.

            (b) Unless a specified period is set forth in this Agreement with
respect to any covenant (in which event such specified period will control and
such covenant will expire upon expiration of such specified period), the
covenants in this Agreement will survive the Closing and remain in effect
indefinitely.

        9.2 Limitations on Liability. (a) For purposes of this Agreement, (i)
"Indemnity Payment" means any amount of Indemnifiable Losses required to be paid
pursuant to this Agreement, (ii) "Indemnitee" means any person or entity
entitled to indemnification under this Agreement, (iii) "Indemnifying Party"
means any person or entity required to provide indemnification under this
Agreement, (iv) "Indemnifiable Losses" means any and all damages, losses,
liabilities, obligations, costs and expenses, and any and all claims, demands or
suits (by any person or entity, including, without limitation, any Governmental
Authority), including, without limitation, the costs and expenses of any and all
actions, suits, proceedings, demands, assessments, judgments, settlements and
compromises relating thereto and including reasonable attorneys' fees and
expenses in connection therewith, and (v) "Third Party Claim" means any claim,
action or proceeding made or brought by any person or entity who or which is not
a party to this Agreement.

            (b) Notwithstanding any other provision hereof or of any applicable
Law, (i) no Indemnitee will be entitled to make a claim against an Indemnifying
Party under Sections 9.3(a)(i) or (ii), or 9.3(b)(i) or (ii), as applicable,
unless and until the aggregate amount of claims asserted for Indemnifiable
Losses under Sections 9.3(a)(i) and (ii), with respect to claims by Purchaser,
or 9.3(b)(i) and (ii), with respect to claims by Seller, exceeds



                                       17
<PAGE>   18

$100,000, in which event the Indemnitee will be entitled to make a claim against
the Indemnifying Party in respect of Indemnifiable Losses only to the extent of
such excess and (ii) no Indemnitee shall be liable for Indemnity Payments under
Sections 9.3(a)(i) or (ii)(other than with respect to a breach of Section 8.1
which is continuing and uncured 30 days after Seller's receipt of written notice
from Purchaser of such a breach), or 9.3(b)(i) or (ii), as applicable, or
payments under Section 8.4, to the extent that the aggregate of such Indemnity
Payments by such Indemnifying Party together with the payments by such
Indemnifying Party under Section 8.4 exceeds 50% of the aggregate amounts paid
by Purchaser to Seller pursuant to Section 4.1 of this Agreement and Section 6.1
of the IP Agreement.

        9.3 Indemnification. (a) Subject to Sections 9.1 and 9.2, Seller agrees
to indemnify, defend and hold harmless Purchaser from and against any and all
Indemnifiable Losses resulting from or arising out of:

                (i) any failure of a representation or warranty of Seller
contained in this Agreement to be true and correct as of the Closing Date;

                (ii) any breach of any agreement or covenant of Seller contained
in this Agreement; and

                (iii) any third party claims regarding Retained Liabilities
arising out of the operation of the Seller's business prior to the Closing which
relate to (A) a lien on the Assets that secures indebtedness, (B) failure to
comply with any "bulk sales" laws applicable to the transactions contemplated
hereby, or (C) an assertion by such third party of a successor liability claim.

            (b) Purchaser agrees to indemnify, defend and hold harmless Seller
from and against any and all Indemnifiable Losses resulting from or arising out
of:

                (i) any failure of a representation or warranty of Purchaser
contained in this Agreement to be true and correct as of the Closing Date;

                (ii) any breach of any agreement or covenant of Purchaser
contained in this Agreement; and

                (iii) any Assumed Liabilities.

        9.4 Defense of Claims. (a) If any Indemnitee receives notice of
assertion or commencement of any Third Party Claim against such Indemnitee with
respect to which an Indemnifying Party is obligated to provide indemnification
under this Agreement, the Indemnitee will give such Indemnifying Party
reasonably prompt written notice thereof, but in any event not later than 15
calendar days after receipt of such notice of such Third Party Claim. Such
notice will describe the Third Party Claim in reasonable detail, will include
copies of all material written evidence thereof and will indicate the estimated
amount, if reasonably practicable, of the Indemnifiable Loss that has been or
may be sustained by the Indemnitee. The Indemnifying Party will have the right
to participate in, or, by giving written



                                       18
<PAGE>   19

notice to the Indemnitee, to assume, the defense of any Third Party Claim at
such Indemnifying Party's own expense and by such Indemnifying Party's own
counsel (reasonably satisfactory to the Indemnitee), and the Indemnitee will
cooperate in good faith in such defense.

            (b) If, within 30 calendar days after giving notice of a Third Party
Claim to an Indemnifying Party pursuant to Section 9.4(a), an Indemnitee
receives written notice from the Indemnifying Party that the Indemnifying Party
has elected to assume the defense of such Third Party Claim as provided in the
last sentence of Section 9.4(a), the Indemnifying Party will not be liable for
any legal expenses subsequently incurred by the Indemnitee in connection with
the defense thereof; provided, however, that if the Indemnifying Party fails to
take reasonable steps necessary to defend diligently such Third Party Claim
within 30 calendar days after receiving written notice from the Indemnitee that
the Indemnitee believes the Indemnifying Party has failed to take such steps or
if the Indemnifying Party has not undertaken to indemnify the Indemnitee in
respect of all Indemnifiable Losses relating to the matter, the Indemnitee may
assume its own defense, and the Indemnifying Party will be liable for all
reasonable costs or expenses paid or incurred in connection therewith. Without
the prior written consent of the Indemnitee, the Indemnifying Party will not
enter into any settlement of any Third Party Claim which would lead to liability
or create any financial or other obligation on the part of the Indemnitee for
which the Indemnitee is not entitled to indemnification hereunder. If a firm
offer is made to settle a Third Party Claim without leading to liability or the
creation of a financial or other obligation on the part of the Indemnitee for
which the Indemnitee is not entitled to indemnification hereunder and the
Indemnifying Party desires to accept and agree to such offer, the Indemnifying
Party will give written notice to the Indemnitee to that effect. If the
Indemnitee fails to consent to such firm offer within 10 calendar days after its
receipt of such notice, the Indemnitee may continue to contest or defend such
Third Party Claim and, in such event, the maximum liability of the Indemnifying
Party as to such Third Party Claim will not exceed the amount of such settlement
offer, plus costs and expenses paid or incurred by the Indemnitee through the
end of such 10 calendar day period.

            (c) A failure to give timely notice or to include any specified
information in any notice as provided in Sections 9.4(a) or 9.4(b) will not
affect the rights or obligations of any party hereunder except and only to the
extent that, as a result of such failure, any party which was entitled to
receive such notice was deprived of its right to recover any payment under its
applicable insurance coverage or was otherwise damaged as a result of such
failure.

            (d) The Indemnifying Party will have a period of 30 calendar days
within which to respond in writing to any claim by an Indemnitee on account of
an Indemnifiable Loss pursuant to Section 9.3 that does not result from a Third
Party Claim (a "Direct Claim"). If the Indemnifying Party does not so respond
within such 30 calendar day period, the Indemnifying Party will be deemed to
have rejected such claim. In the event the Indemnifying Party rejects, or is
deemed to have rejected, a Direct Claim, the Indemnitee will be free to pursue
such remedies as are available at law or in equity in respect of such Direct
Claim.

Purchaser hereby assigns and, if and as Seller may request in the future, agrees

combine, alter or obscure the Adaptec Marks in any way or authorize any third

PRICE ALLOCATION


<PAGE>   8

reflected in the Purchase Price Allocation Agreement in a manner consistent with
Treasury Regulation Section 1.1060-lT(f).

            (ii) Consistent Treatment and Characterization of Amounts. For all
Tax purposes, Purchaser and Seller agree to report the transactions contemplated
in this Agreement in a manner consistent with the Purchase Price Allocation
Agreement, and will not take any position inconsistent therewith in any Tax
return, in any refund claim, in any litigation or otherwise, unless required to
do so by a governmental authority. Seller and Purchaser shall each be
responsible for the preparation of their own Section 1060 statements and forms
in accordance with applicable Tax laws, and each shall execute and deliver to
each other such statements and forms as are reasonably requested by the other
party.

        SECTION 2.4. Closing. Subject to the terms and conditions of this
Agreement, the sale, purchase, license and transfer of the Business Assets and

Alto, California at 10:00 a.m., local time, on the second business day after the

designated by Purchaser:

        (i) all Business Assets to the facility or other location specified by

and expense; provided, that if Purchaser directs that any Business Assets be
delivered to a location more than fifty miles from either Seller's facilities at
Milpitas, California or Longmont, Colorado, depending on which location such
Business Asset is located, such delivery shall be at Purchaser's sole cost and
expense;

        (ii) executed counterparts of each Ancillary Agreement to which Seller
is a party;

        (iii) (x) assignments substantially in the forms of EXHIBIT H (the

with the United States Patent and Trademark Office; and (y) assignments from
Seller to Purchaser of all registered mask works included in the Purchased

        (iv) all other items required to be delivered by Seller at the Closing

Ancillary Agreement.

        SECTION 2.6. Closing Deliveries by Purchaser. At the Closing, Purchaser

<PAGE>   9

        (ii) executed counterparts of each Ancillary Agreement to which
Purchaser is a party; and

        (iii) all other items required to be delivered by Purchaser at the
Closing pursuant to Section 8.1 of this Agreement or any other provision hereof
or any Ancillary Agreement.

        SECTION 2.7. Unassignable Assets. Notwithstanding any other provision of
this Agreement or any of the Ancillary Agreements, to the extent that any of the
Seller Contracts or any other assets constituting part of the Purchased Assets
are not assignable or otherwise transferable to Purchaser or if any of the
Licensed Assets may not be licensed to Purchaser without the consent, approval
or waiver of another party thereto or any third party (including any
governmental agency), or if such assignment, transfer or license would
constitute a breach thereof or a violation of any applicable law or agreement
with any third party, then neither this Agreement nor such Ancillary Agreements
shall constitute an assignment or transfer (or an attempted assignment or
transfer) thereof until such consent, approval or waiver of such party or
parties has been duly obtained. With respect to each Seller Contract or Licensed
Asset whose assignment, transfer or license to Purchaser requires the consent,
approval or waiver of another party thereto or any third party, Seller shall use
all commercially reasonable efforts to obtain such consent, approval or waiver
of such other party or parties or such third party to such assignment or
transfer as promptly as practicable. To the extent that the consents, approvals
and waivers referred to in this Section are not obtained by Seller, Seller shall
use all commercially reasonable efforts to (a) provide to Purchaser, at the
request and expense of Purchaser, the financial and business benefits of such
Seller Contract or Licensed Asset and (b) enforce, at the request and expense of
Purchaser, for the account of Purchaser, any rights of Seller arising from any
such Seller Contract (including without limitation the right to elect to
terminate such Seller Contract in accordance with the terms thereof upon the
advice of Purchaser). With regard to the expenses described in the preceding
sentence, Purchaser shall only be responsible for the direct expenses of Seller
in connection therewith, and if only a portion of such benefits are provided to
Purchaser, Purchaser and Seller shall agree in good faith upon a reasonable pro
rata payment by Purchaser of the expenses incurred in connection with such
benefits. Purchaser agrees to cooperate with Seller and supply relevant
information to such party or parties or such third party in order to assist
Seller in its obligations under this Section. Notwithstanding the foregoing,
nothing contained herein shall obligate Seller or Purchaser to expend or pay any
amount to third parties to obtain any consents, approvals or waivers.

                                   ARTICLE III

                    REPRESENTATIONS AND WARRANTIES OF SELLER

        Seller hereby represents and warrants to Purchaser that, except as
expressly set forth in the Seller's Disclosure Letter, all of the following
statements, representations and warranties are true and correct:

        SECTION 3.1. Organization and Good Standing of Seller. Each of AIM and
AMS is a corporation or similar entity duly organized, validly existing and in
good standing under the laws of its jurisdiction of organization. Seller has all
requisite corporate power and authority to carry on the Desktop Peripherals
Business as now conducted and to enter into this Agreement and the Ancillary
Agreements and the transactions contemplated hereby and thereby.



<PAGE>   10

        SECTION 3.2. Authorization and Validity. The execution and delivery of
this Agreement and the Ancillary Agreements and the performance of all
obligations of Seller hereunder and thereunder, has been duly and validly
authorized by all necessary corporate and shareholder action on the part of
Seller. This Agreement has been, and at the Closing the other Ancillary
Agreements will be, duly executed and delivered by Seller. This Agreement
constitutes, and, upon Seller's execution of each of the other Ancillary
Agreements, each of the other Ancillary Agreements will constitute, a legal,
valid and binding obligation of Seller enforceable against Seller in accordance
with its terms, except (i) as limited by applicable bankruptcy, insolvency,
reorganization, moratorium, and other laws of general application affecting
enforcement of creditors' rights generally; and (ii) as limited by laws relating
to the availability of specific performance, injunctive relief or other
equitable remedies.

        SECTION 3.3. No Conflict. The execution, delivery and performance of
this Agreement and the Ancillary Agreements by Seller and the consummation of
the transactions contemplated hereby and thereby, subject to compliance with the
consents required in SCHEDULE 9, do not and will not (a) result in a violation
or default in any material respect of any provision of Seller's charter
documents or any judgment, order, writ or decree applicable to Seller, (b)
constitute a default (or event which with the giving of notice or lapse of time,
or both, would become a breach, violation or default) under, or give to others
any rights of termination, amendment, acceleration or cancellation of, any of
the Seller Contracts or (c) result in the creation of any material Encumbrance
on any of the Business Assets.

        SECTION 3.4. Consents. No consent, approval, order or authorization of
or registration, qualification, designation, declaration or filing with, any
governmental entity on the part of Seller is required in connection with the
consummation of the transactions contemplated by this Agreement and the
Ancillary Agreements, except for compliance with the requirements of the HSR
Act. SCHEDULE 9 sets forth a true and complete list of each and every Business
Asset with respect to which the consent or approval of any third party or
governmental authority is required in order for Seller to assign, transfer or
license to Purchaser any of the Business Assets or any rights or obligations
under Seller Contracts.

Third Party Assets) and has good and marketable title in and to all of the
Purchased Assets (other than Third Party Assets), free and clear of all
Encumbrances whatsoever. Title to all the Purchased Assets (other than Third

the right to transfer the Third Party Assets, without restriction and without

accordance with their respective terms (except as limited by applicable
bankruptcy, insolvency, reorganization, moratorium, and other laws of general
application affecting enforcement of creditors' rights generally and as limited
by laws relating to


<PAGE>   11

the availability of specific performance, injunctive relief or other equitable
remedies). Neither Seller nor, to Seller's knowledge, any other party to any
Seller Contract, is in material breach or default in performance of any of their
respective obligations thereunder, and no event exists which, with the giving of
notice or lapse of time or both, would constitute a material breach, default or
event of default on the part of Seller or, to Seller's knowledge, on the part of
any other party, to any Seller Contract that is continuing unremedied.

        SECTION 3.7. Litigation. There is no claim, action, suit, arbitration,
mediation, investigation or other proceeding of any nature pending or, to
Seller's knowledge, threatened, at law or in equity, by way of arbitration or
before any court, governmental department, commission, board or agency that
adversely affects, contests or challenges Seller's authority, right or ability
to sell, convey or license any of the Business Assets to Purchaser hereunder or
otherwise perform Seller's obligations under this Agreement or any of the
Ancillary Agreements. There are no judgments, decrees, injunctions or orders of
any court, governmental department, commission, agency, instrumentality or

        (a) Ownership. Seller owns or has the right to use pursuant to license,
sublicense, agreement, or other valid permission, all Intellectual Property
Rights in the Intangible Assets, Product Designs and Purchased Technology

Intellectual Property Rights in the Intangible Assets, Product Designs and
Purchased Technology Deliverables.

        (b) Non-Infringement. To Seller's knowledge, the Business Assets (other
than Third Party Assets) have not infringed or violated and currently do not
infringe, violate, or misappropriate any Intellectual Property Rights (other
than trademarks) of any third party, and no third party has asserted or
threatened to assert against Seller any claim of infringement or
misappropriation of any such rights. To Seller's knowledge, no third party has
interfered with, infringed upon, misappropriated, or otherwise come into
conflict with any of the Intellectual Property Rights in and to the Business
Assets (other than Third Party Assets).

        (c) Licenses. SCHEDULE 10 sets forth each material license Seller has
granted to any third party with respect to any Business Asset. SCHEDULE 10 sets
forth each material Intellectual Property Right in connection with the
development, manufacture, use or sale of the Products that a third party owns
and that Seller uses pursuant to a license, sublicense, agreement or other
permission, except for licenses entered into in the ordinary course of the
Desktop Peripherals Business or standard "shrink-wrap" licenses for
off-the-shelf software products.

        SECTION 3.9. Compliance with Laws. To Seller's knowledge, Seller has
complied in all material respects with and has not received any notices of
violation with respect to, any federal, state or local statute, law or
regulation of any country of the world applicable to any of the Business Assets.

        (a) Tax Assessments. There is no claim or assessment pending or, to the
knowledge of Seller, threatened, for any alleged deficiency in Tax attributable
to Seller or the affiliated group of which Seller is a member (the "SELLER

<PAGE>   12

knowledge of Seller, there is no audit or investigation with respect to any
liability of Seller or the Seller Group for Taxes relating to the Business
Assets.

        (b) No Tax Liens. There are (and as of immediately following the Closing
there will be) no Encumbrances on any of the Business Assets relating to or
attributable to Taxes.

        SECTION 3.11. Employees. Set forth in SCHEDULE 11 is a complete and
accurate list, as of the Effective Date, of the employees of Seller who
currently work full-time in the Desktop Peripherals Business ("EMPLOYEES"),
including, for each Employee, such Employee's title, date of hire and adjusted
service date and location at which such Employee is working as of the Effective
Date. SCHEDULE 11 sets forth, for each Employee, a true and accurate list of the
current annual base salary, their status as exempt or non-exempt, all bonuses,
profit sharing, or commissions accrued or payable, any special compensatory or
reimbursement arrangements, comp time or other arrangements with such Employees
and any other compensatory agreements between such Employee and Seller.

        SECTION 3.12. Pension and Employee Benefit Matters. Neither Seller nor
any entity which, within the last 5 years, has been under common control of or
affiliated with Seller (an "ERISA AFFILIATE") within the meaning of Section
414(b), (c) or (m) of the Internal Revenue Code, has ever been obligated to
contribute to any "multi-employer plan" as such term is defined in Section 3(37)
of ERISA. No liability to the Pension Benefit Guaranty Corporation is expected
to be incurred in connection with the transactions contemplated hereby.

        SECTION 3.13. Customers. SCHEDULE 12 is a true and complete list of all

contemplated by this Agreement, or dealt with anyone purporting to act in the
capacity of a broker, finder, investment banker or agent with respect thereto.

        SECTION 3.16. Restrictive Agreements. No Business Asset is bound or
affected by any judgment, injunction, order or agreement that restricts or
prohibits its use, or following the Closing, would restrict or prohibit its use,
in the Desktop Peripherals Business as presently conducted by Seller.

        SECTION 5.2. Consent of Third Parties. Seller shall use all commercially
reasonable efforts to obtain the consent in writing of all persons, if any,
necessary to permit Seller to assign and transfer all of the Purchased Assets
free and clear of all material Encumbrances, and license all of the Licensed
Assets, to Purchaser.

        SECTION 5.3. Access to Information. From the Effective Date until the
earlier of the Closing Date or the termination of this Agreement according to
its terms, Seller will afford to the representatives of Purchaser, including its
counsel and auditors, during normal business hours, access to any and all of the
Business Assets to the end that Purchaser may have a reasonable opportunity to
make such a full investigation of the Business Assets in advance of the Closing
Date as it shall reasonably desire, and the officers of Seller will confer with
representatives of Purchaser and will furnish to Purchaser, either orally or by
means of such records, documents, and memoranda as are available or reasonably
capable of preparation, such information as Purchaser may reasonably request,
and Seller will furnish to Purchaser's auditors all consents and authority that
they may reasonably request in connection with any such examination.

        SECTION 5.4. Use of Facilities; Manufacturing Services. For a period of
up to three months following the Closing Date, Seller shall permit Purchaser to
occupy and use certain facilities of the Seller, according to the terms and
conditions of the Facilities Agreement. For a period of up to nine months
following the Closing Date, Seller will provide Purchaser with certain
fabrication, manufacturing and testing services for the Products, according to
the terms and conditions of the Manufacturing Agreement.

        SECTION 5.5 Further Actions. Each of the parties hereto shall, at its
own expense, execute and deliver such documents and other papers and take such
further actions as may be required to carry out the provisions of this Agreement
and the Ancillary Agreements, to cause the conditions to Closing set forth in
Article VIII to be fulfilled as promptly as possible, and to give effect to the
transactions contemplated by this Agreement and the Ancillary Agreements. In
case at any time after the Closing Date any further action is necessary or
desirable to carry out the provisions of this Agreement or the Ancillary
Agreements, each of the parties will take such



<PAGE>   15

further action (including the execution and delivery of such further instruments
and documents). Seller will sign and deliver any and all instruments and
documents necessary or appropriate to fully effect and perfect the transfer or
license, as the case may be, to Purchaser of the Business Assets. If the
Employee interviews described in clause (ii) of the penultimate sentence of
Section 6.1 identify tangible assets which are owned by Seller, are not being
transferred to Purchaser pursuant to this Agreement, and are used by an Employee
in the ordinary course of performing services in the Desktop Peripherals
Business, Seller and Purchaser shall, in good faith, determine whether such
asset should be (1) transferred to Purchaser without additional cost, (2) sold
to Purchaser in a separate transaction for additional consideration or (3)
retained by Seller.

        SECTION 5.6. Confidentiality.

        (a) All copies of financial information, marketing and sales
information, pricing, marketing plans, business plans, financial and business
projections, manufacturing processes and procedures, formulae, methodologies,
inventions, product designs, product specifications and drawings, and other
confidential and/or proprietary information of a party (the "DISCLOSING PARTY")
disclosed to the other party (the "NON-DISCLOSING PARTY") in the course of
negotiating the transactions contemplated by this Agreement ("CONFIDENTIAL
INFORMATION") will be held in strict confidence and not used or disclosed by the
Non-Disclosing Party or any of its employees, affiliates or stockholders and,
upon termination of this Agreement in accordance with its terms and upon the
Disclosing Party's written request to the Non-Disclosing Party, will be promptly
destroyed by the Non-Disclosing Party or returned to the Disclosing Party. The
Non-Disclosing Party's employees, affiliates and stockholders will not be given
access to Confidential Information except on a "need to know" basis. It is
agreed that Confidential Information will not include information that: (a) is
proven to have been known to the Non-Disclosing Party prior to receipt of such
information from the Disclosing Party; (b) is disclosed by a third party having
the legal right to disclose such information and who owes no obligation of
confidence to the Disclosing Party; (c) is now, or later becomes part of the
general public knowledge or literature in the art, other than as a result of a
breach of this Agreement by the Non-Disclosing Party; or (d) is proven to be
independently developed by the Disclosing Party without the use of any
Confidential Information. The provisions of this Section 5.6(a) shall supersede
the provisions of the letter agreement, dated as of October 6, 1998, between
Purchaser and Bear Stearns & Co., Inc., on behalf of Seller (the
"CONFIDENTIALITY AGREEMENT"); provided, however, that upon the termination or
expiration of this Agreement, the Confidentiality Agreement shall continue in
full force and effect as a binding agreement between Purchaser and Seller.

        (b) At all times following the Closing, Seller will: (i) continue to
hold all Confidential Information which constitutes Purchased Assets
(collectively, "ACQUIRED CONFIDENTIAL INFORMATION") in strict confidence, (ii)
will not use for itself or third parties any Acquired Confidential Information,
and (iii) upon Purchaser's request, promptly destroy or deliver to Purchaser any
Acquired Confidential Information in Seller's possession or control; provided,
that Seller may internally use the original copies of all Business Records
solely to prepare and file Tax returns and prepare Seller's financial
statements, and Seller may disclose any Acquired Confidential Information as may
be required to comply with requests from all governmental agencies; provided,
further, that Seller must provide Purchaser with prior written notice of any
proposed disclosure to government agencies and with respect to the U.S.
Securities and Exchange Commission, an opportunity to seek confidential
treatment of such proposed disclosure. It is agreed that Acquired Confidential
Information will not include information that is now, or later becomes, part of
the general public knowledge or literature in the art, other than as a result of
a


<PAGE>   16

breach of this Agreement by Seller. Following the Closing, Purchaser's
obligations pursuant to Section 5.6(a) shall terminate with respect to
Confidential Information which constitutes Acquired Confidential Information.

        SECTION 5.7. Public Announcements. On and prior to the Closing Date,
Purchaser and Seller shall advise and confer with each other prior to the
issuance of any reports, statements or releases concerning this Agreement
(including the exhibits hereto) and the transactions contemplated hereby.
Purchaser and Seller will agree in good faith on the text and timing of any
public disclosure prior to the Closing or with respect to such matters, except
as may be required by law, court process, securities exchange listing agreement
or the rules of the National Association of Securities Dealers.

        SECTION 5.8. Books and Records. If, in order properly to prepare
documents required to be filed with governmental authorities (including Tax
authorities) or its financial statements, it is necessary that any party hereto
or any successors be furnished with additional information relating to the
Business Assets, and such information is in the possession of any other party
hereto, such party agrees to use all commercially reasonable efforts to promptly
furnish such information to the party needing such information, at the cost and
expense of the party being furnished such information. From and after the
Effective Date and continuing after the Closing, Seller shall cooperate with
Purchaser and provide to Purchaser at Purchaser's expense all financial
information that may be required to enable Purchaser to comply with all
applicable laws, rules and regulations, and any governmental filing
requirements, with respect to reporting and reflecting the transactions
contemplated by this Agreement and the Ancillary Agreements.

        SECTION 5.9. Regulatory and Other Authorizations; Consents.

        (a) Efforts. Each party hereto will use all commercially reasonable
efforts to obtain all authorizations, consents, orders and approvals of all
federal, state and local regulatory bodies and officials that may be or become
necessary for the execution and delivery of, and the performance of its
obligations pursuant to, this Agreement and the Ancillary Agreements and will
cooperate fully with the other party in promptly seeking to obtain all such
authorizations, consents, orders and approvals. Each party hereto agrees to make
an appropriate filing of a Notification and Report Form pursuant to the HSR Act
with respect to the transactions contemplated hereby as promptly as is
practicable after the date hereof and to supply promptly any additional
information and documentary material that may be requested by any governmental
authority pursuant to the HSR Act. The parties hereto will not take any action
that will have the effect of delaying, impairing or impeding the receipt of any
required approvals. Without limiting the generality of the parties' undertakings
pursuant to this Section, the parties shall use all commercially reasonable
efforts to prevent the entry in a judicial or administrative proceeding brought
under any antitrust or similar law by the Federal Trade Commission, the
Department of Justice or any other United States federal or state, or non-U.S.
government or governmental authority (an "ANTITRUST AUTHORITY") or any other
party of any permanent or preliminary injunction or other order that would make
consummation of the acquisition of the Purchased Assets in accordance with the
terms of this Agreement unlawful or that would prevent or delay such
consummation. In connection therewith, if any administrative or judicial action
or proceeding is instituted (or threatened to be instituted) challenging any
transaction contemplated by this Agreement as violative of any antitrust or
similar law, each of the parties hereto shall cooperate and use all commercially
reasonable efforts to contest and resist any such action or proceeding and to
have vacated, lifted, reversed, or overturned any decree, judgment, injunction
or other order, whether


<PAGE>   17
temporary, preliminary or permanent, that is in effect and that prohibits,
prevents, or restricts consummation of any such transaction, unless by mutual
agreement the parties decide that litigation is not in their respective best
interests.

        (b) Communications. Each party hereto shall promptly inform the other of
any communication between such party and an Antitrust Authority regarding any of
the transactions contemplated hereby. If any party or any affiliate of such
party receives a request for additional information or for documents or any
material from an Antitrust Authority, or an Antirust Authority makes any
objection with respect to the transactions contemplated hereby, then such party
shall use all commercially reasonable efforts to promptly resolve such request
or such objections. Each party shall use all commercially reasonable efforts to
provide prior disclosure to, and coordinate with the other parties and their
counsel in connection with the submission of written materials by such party to
an Antitrust Authority in connection with HSR Act compliance or the merger
control or competition regulations of any other country, and prior to initiating
any oral communications with such Antitrust Authorities by such party. Each
party hereto will cooperate in connection with reaching any understandings,
undertakings or agreements (oral or written) involving an Antitrust Authority in
connection with the transactions contemplated hereby.

        SECTION 5.10. Taxes. To the extent that failure to do so could
materially adversely affect the Business Assets, Seller shall, (a) continue to
file within the time period for filing all returns and reports relating to
Taxes, and such returns and reports shall be true, correct and complete, and (b)
pay when due any and all Taxes attributable to or levied or imposed upon the
Business Assets for periods (or portions thereof) through the Closing Date.

        SECTION 5.11. Export Compliance. Without prior authorization of the
United States Office of Export Administration, neither Seller nor Purchaser
shall knowingly export or reexport (including but not limited to delivery to a
foreign national) directly or indirectly any technical data received from the
other party, any technical data relating to the commodities received from the
other party or any immediate products (including processes and services)
produced directly by use of any of such technical data to any country to the
extent such export or reexport violates the Export Control Regulations of the
Bureau of International Commerce of the United States Department of Commerce.

        SECTION 5.12. No Other Bids. Until the earlier to occur of (a) the
Closing or (b) the termination of this Agreement pursuant to its terms, Seller
shall not, and Seller shall not authorize any of its officers, directors,
employees, agents or other representatives to, directly or indirectly, (i)
initiate, solicit or encourage (including by way of furnishing evaluation
material or other information regarding the Desktop Peripherals Business or the
Business Assets) any inquiries, or make any statements to third parties which
may reasonably be expected to lead to any proposal, concerning the sale of the
Desktop Peripherals Business or all or a portion of the Business Assets, or (ii)
negotiate, engage in any substantive discussions, or enter into any agreement,
with any person concerning the sale of the Business Assets.

        SECTION 5.13. Accounts Receivable.

        (a) Promptly, but in no event more than fifteen business days, following
the Effective Date, Purchaser shall arrange with a bank or other financial
institution approved in writing by Seller (THE "A/R BANK") to open a "lockbox"
bank account (THE "LOCKBOX ACCOUNT") for the purpose of receiving payments of
accounts receivable in respect of the Desktop Peripherals


<PAGE>   18

Business, including the Closing Accounts Receivable. Seller and Purchaser shall
agree in good faith upon written instructions to be given to the A/R Bank (which
shall be irrevocable unless rescinded by both Seller and Purchaser) which shall
provide that (i) all deposits to and withdrawals from such account shall be
promptly reported to both Seller and Purchaser, (ii) that such account shall be
managed in accordance with the provisions of this Section, and (iii) that upon
receipt of written notice by either Seller or Purchaser that a dispute regarding
such account has arisen between the parties, that no amounts shall be paid out
of such account until the A/R Bank has received written notice from both parties
that such dispute has been resolved.

        (b) Not less than two days prior to the Closing, Seller shall deliver to
Purchaser a detailed summary (by customer and Product) of the Closing Accounts
Receivable. Immediately following the Closing, Seller shall send to each
customer of the Desktop Peripherals Business who owes a receivable included in
the Closing Accounts Receivable (such receivable, a "RCAR"), an instruction that
all receivables in respect of Products sold to such customer shall be paid to
the Lockbox Account. Purchaser will use its good faith efforts to have each such
customer pay in full all receivables included in the Closing Accounts
Receivable. The parties agree that for any customer which has a RCAR, all
payments received from or on behalf of such customer for a Product which is
included in a RCAR (whether or not such payment is in respect of the RCAR) shall
be allocated to the RCAR for such Product of such customer. Upon payment in full
of all RCARs of a customer, Purchaser shall have no further obligations under
this Section in respect of the receivables of such customer.

        (c) The A/R Bank shall promptly transfer all payments deposited into the
Lockbox Account in respect of RCARs (or allocated to RCARs pursuant to paragraph
(b) of this Section) 95 % to Seller and 5% to Purchaser. Purchaser will allow
Seller and its representatives to have reasonable access to the books and
records of Purchaser in order to verify ongoing compliance by Purchaser with its
covenants set forth in this Section.

        SECTION 5.14. Third Party Software. In respect of any software owned by
a third party and loaded on any hardware purchased by Purchaser under this
Agreement, Purchaser shall promptly either obtain a license for such software or
destroy such software. Purchaser shall be liable for, and shall indemnify and
hold harmless Seller from, any and all liabilities and expenses (including the
fees and expenses of counsel) arising in connection with Purchaser's failure to
obtain such licenses or destroy such software.

        SECTION 5.15. Third Party Tools. Seller shall use all commercially
reasonable efforts to have licenses to the third party tools (as set forth in
Schedule 13) transferred to Purchaser, which licenses shall be in an amount
approximately equal to the number of Hired Employees.

        SECTION 5.16. Survival of Covenants. Each of the covenants set forth in
Sections 5.4, 5.5, 5.6, 5.7, 5.8, 5.10, 5.12, 5.13, 5.14, 5.15 and 5.16 shall

leave or similar accrued benefits with respect to such Employees attributable to
periods of employment or service with Seller, consistent with Seller's policies
and applicable law, and shall make such payment within the statutory time period
therefor.

        (c) Seller agrees to comply with the provisions of any statute or
regulation regarding termination of employment, plant closing or layoffs and to
perform all obligations required by Seller with respect to the cessation of any
operations of the Desktop Peripherals Business or the termination,

        SECTION 10.3. Indemnification by Purchaser. Purchaser agrees, subject to
the other terms, conditions and limitations of this Agreement (including the
provisions of Section 10.6(b) hereof), to indemnify the Seller Indemnitees

        SECTION 10.5. Procedures for Indemnification.

        (a) As used herein, an "INDEMNIFIED PARTY" means a Purchaser Indemnitee
seeking indemnification pursuant to Section 10.2 hereof or a Seller Indemnitee
seeking indemnification pursuant to Section 10.3 hereof. The Indemnified Party
agrees to give the other party ("INDEMNITOR") prompt written notice of any
event, or any claim, action, suit, demand, assessment, investigation,
arbitration or other proceeding by or in respect of a third party (a "THIRD
PARTY CLAIM") of which it has knowledge, for which such Indemnified Party is
entitled to indemnification under this Article X (including in any case copies
of any summons, complaint or other pleading which may have been served on it and
any written claim, demand, invoice, billing or other document evidencing or
asserting the same). No delay on the part of an Indemnified Party in giving the
Indemnitor notice of a Third Party Claim shall relieve the Indemnitor from any
obligation hereunder unless the Indemnitor is prejudiced thereby.

        (b) Within twenty days of delivery of such written notice, the
Indemnitor may, at the expense of the Indemnitor, elect to take all necessary
steps properly to contest any Third Party Claim or to prosecute such Third Party
Claim to conclusion or settlement; provided, that without the prior written
consent of an Indemnified Party, the Indemnitor will not enter into any
settlement of a Third Party Claim which would lead to liability or create any
financial or other obligation on the part of such Indemnified Party for which
such Indemnified Party is not indemnified hereunder. If the Indemnitor makes the
foregoing election, an Indemnified Party will have the right to participate at
its own expense in all proceedings. If the Indemnitor does not make such
election or if the Indemnitor fails to take reasonable steps necessary to
diligently defend such Third Party Claim within twenty days after receiving
notice from the Indemnified Party that the Indemnified Party believes that the
Indemnitor has failed to take such steps, an Indemnified Party shall be free to
handle the prosecution or defense of any such Third Party Claim, will take all
necessary steps to contest the Third Party Claim or to prosecute such Third
Party Claim to conclusion or settlement satisfactory to such Indemnified Party
at the sole cost and expense of the Indemnitor (including reasonable attorney's
and expert's fees and expenses and court and arbitration costs), will notify the
Indemnitor of the progress of any such Third Party Claim, will permit the
Indemnitor, at the sole cost of the Indemnitor, to participate in such
prosecution or defense and will provide the Indemnitor with reasonable access to
all relevant information and documentation relating to the Third Party Claim and
the prosecution or defense thereof. In any case, the party not in control of the
Third Party Claim will cooperate with the other party in the conduct of the
prosecution or defense of such Third Party Claim. Notwithstanding the foregoing,
if an Indemnified Party is offered a written settlement proposal by a third
party that has as its sole component the payment of money by the Indemnified
Party and the Indemnitor recommends to the Indemnified Party in writing that it
accept such settlement proposal (the "SANCTIONED SETTLEMENT") and the
Indemnified Party refuses to accept such settlement proposal, in such event if
the ultimate settlement terms agreed to by the Indemnified Party with such third
party or the final monetary damages award against the Indemnified Party (either,
a "FINAL SETTLEMENT AMOUNT"), is greater than the amount of the Sanctioned
Settlement, the Indemnified Party shall be responsible for the differential
between the Final Settlement Amount and the Sanctioned Settlement and the
Indemnitor's liability shall be limited to the amount specified in the
Sanctioned Settlement.

        SECTION 10.6. Limitations on Indemnification.

        (a) Limits on Seller Indemnification.

            (i) Seller shall not be required to provide indemnification under
Section 10.2 unless and until the aggregate Loss for which one or more Purchaser
Indemnitees seeks indemnification thereunder exceeds an aggregate of five
hundred thousand dollars ($500,000), in which event Seller shall be liable to
indemnify the Purchaser Indemnitees for aggregate Loss which exceeds five
hundred thousand dollars ($500,000).

            (ii) The maximum aggregate Loss recoverable by Purchaser Indemnitees
(considered together as a group) against Seller under Section 10.2 and 10.4, in
the aggregate, shall not exceed ten million dollars ($10,000,000).

        (b) Limits on Purchaser Indemnification.

            (i) Purchaser shall not be required to provide indemnification under
Section 10.3 unless and until the aggregate Loss for which one or more Seller
Indemnitees seeks indemnification thereunder exceeds an aggregate of five
hundred thousand dollars ($500,000), in which event Purchaser shall be liable to
indemnify the Seller Indemnitees for aggregate Loss which exceeds five hundred
thousand dollars ($500,000).

            (ii) The maximum aggregate Loss recoverable by Seller Indemnitees
(considered together as a group) against Purchaser under Section 10.3 and 10.4,
in the aggregate, shall not exceed ten million dollars ($10,000,000).

        (c) Time Limits. Notwithstanding anything herein to the contrary, no
claim for indemnification under Sections 10.2 or 10.3 may be brought after the
two year anniversary of the Closing Date.

        SECTION 10.7. Exclusive Remedy. From and after the Closing Date, the
foregoing provisions of Article X, together with the other specific
indemnifications and allocations of liability specified in other Sections or
Articles of this Agreement and/or the Ancillary Agreements, are the sole and
exclusive remedy of an Indemnified Party for a breach of a representation,
warranty, covenant or agreement of the other party contained in this Agreement
or any Ancillary Agreement.

                                   ARTICLE XI

                               DISPUTE RESOLUTION

        SECTION 11.1. Management Negotiation.

        (a) Purchaser and Seller shall attempt to resolve disputes between the
Purchaser and the Seller arising out of or in connection with this Agreement
through good faith negotiations as provided herein. The parties agree that
disputes shall be fully discussed by representatives of Purchaser and the Seller
involved in the dispute in an attempt to achieve a prompt resolution of such
dispute. In the event that such dispute shall not be promptly resolved by the
mutual agreement of such representatives, the dispute shall be submitted to
senior management representatives of Purchaser and Seller. Such senior
management


<PAGE>   27

representatives of Purchaser and Seller shall meet and fully discuss such
dispute in an attempt to achieve a prompt resolution of the dispute. If such
dispute is not promptly resolved by the mutual agreement of such senior
management representatives of Purchaser and Seller, Purchaser and Seller shall
be free to exercise any of the remedies available to it (i) pursuant to the
terms of this Agreement or (ii) otherwise at law or in equity.

        (b) Purchaser and Seller acknowledge that, from time to time, certain
material disputes arising out of or in connection with this Agreement may
objectively require immediate resolution. Accordingly, any such dispute may, at
the option of either the Purchaser or the Seller, be processed through an
abbreviated mediation process. Such abbreviated mediation process shall entail
submitting any such dispute to the senior management representatives of each of
the Purchaser and Seller designated by each of the Purchaser and the Seller for
a prompt and expeditious resolution. In the event that a prompt and expeditious
resolution of such dispute is not achieved through the mutual agreement of such
senior management representatives of the Purchaser and the Seller, Purchaser and
Seller shall be free to exercise any of the remedies available to it (i)
pursuant to the terms of this Agreement or (ii) otherwise at law or in equity.

        (c) Purchaser and Seller agrees to act reasonably and in good faith in
connection with all matters arising out of or in connection with this Agreement
that are submitted to the mediation process set forth in this Article XI.

        SECTION 11.2. Waiver of Jury Trial. The parties hereby waive trial by
jury in any litigation in any court with respect to, in connection with, or
arising out of this Agreement, the Ancillary Agreements or the transactions
contemplated thereby.

                                   ARTICLE XII

                               GENERAL PROVISIONS

limitation, fees and disbursements of counsel, financial advisors and
accountants, incurred in connection with this Agreement and the transactions
contemplated hereby shall be paid by the party incurring such costs and
expenses, whether or not the Closing shall have occurred.

        SECTION 12.2. Notices. All notices, requests, claims, demands and other
communications hereunder shall be in writing and shall be given or made by
delivery in person, by courier service, by telecopy (confirmed in writing), or

mailed by registered or certified mail, on the third business day following
deposit in the mails, to the parties at the following addresses (or at such

herein, express or implied, is intended to or shall confer upon any other person

legal or equitable right, benefit or remedy of any nature whatsoever under or by

termination of this Agreement.

        SECTION 12.11. Counterparts. This Agreement may be executed in one or
more counterparts, and by the different parties hereto in separate counterparts,

the power to control the activities and operations of any other, and the
parties' status is, and at all times, will continue to be, that of independent
contractors with respect to each other. No party will have any power or
authority to bind or commit any other. No party will hold itself out as having
any authority or relationship in contravention of this Section.
