        AGREEMENT AND PLAN OF MERGER AND REORGANIZATION, dated as of October 27,
1999 (this "AGREEMENT"), by and among C-Cube Microsystems Inc., a Delaware
corporation (the "COMPANY"), and Harmonic Inc., a Delaware corporation
("PARENT").

                               W I T N E S S E T H

        WHEREAS, the respective Boards of Directors of Parent and the Company
have each (i) determined that the Merger (as defined in Section 1.1(a) hereof)
is advisable and fair to, and in the best interests of, their respective
stockholders and (ii) approved this Agreement and the Merger upon the terms and
subject to the conditions set forth herein, and in accordance with the Delaware
General Corporation Law (the "DGCL"), whereby each issued and outstanding share
of common stock, par value $.001 per share (the "COMMON STOCK"), of the Company
(other than shares of Common Stock owned, directly or indirectly, by the Company
or by Parent immediately prior to the Effective Time (as defined in Section
1.1(b) hereof) and Dissenting Shares (as defined in Section 1.2(c) hereof),
will, upon the terms and subject to the conditions and limitations set forth
herein, be converted into shares of Common Stock, par value $.001 per share, of
Parent (the "PARENT SHARES") and, if the Semi Sale (as defined in Section 1.5(a)
hereof) has been consummated, the Semi Sale Consideration (as defined in Section
1.5(b)) in accordance with the provisions of Article I of this Agreement; and

        WHEREAS, for federal income tax purposes, the Merger is intended to
qualify as a reorganization under the provisions of Section 368(a) of the United
States Internal Revenue Code of 1986, as amended (the "CODE").

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

                                   ARTICLE I

                                   THE MERGER

        SECTION 1.1 THE MERGER.

            (a) Upon the terms and subject to the conditions of this Agreement,
and in accordance with the DGCL, at the Effective Time, the Company shall be
merged (the "MERGER") with and into Parent, whereupon the separate existence of
the Company shall cease, and Parent shall continue as the surviving corporation
(sometimes referred to herein as the "SURVIVING CORPORATION") and shall continue
to be governed by the laws of the State of Delaware and shall continue under the
name "Harmonic Inc."

            (b) Concurrently with the Closing (as defined in Section 1.7
hereof), the Company and Parent shall cause a certificate of merger
substantially in the form attached hereto as Exhibit A (the "CERTIFICATE OF
MERGER") with respect to the Merger to be executed and filed with the Secretary
of State of the State of Delaware (the "SECRETARY OF STATE") as provided in

<PAGE>   6
the DGCL. The Merger shall become effective on the date and time at which the
Certificate of Merger has been duly filed with the Secretary of State of the
State of Delaware in accordance with Section 251 of the DGCL or at such other
date and time as is agreed between the parties and specified in the Certificate
of Merger, and such date and time is hereinafter referred to as the "EFFECTIVE
TIME."

            (c) The Merger shall have the effects set forth in the DGCL. Without
limiting the generality of the foregoing and subject thereto, from and after the
Effective Time, the Surviving Corporation shall possess all properties, rights,
privileges, immunities, powers and franchises and be subject to all of the
obligations, restrictions, disabilities, liabilities, debts and duties of the
Company and Parent.

        SECTION 1.2 EFFECT ON COMMON STOCK. At the Effective Time:

            (a) CANCELLATION OF SHARES OF COMMON STOCK. Each share of Common
Stock held by the Company as treasury stock and each share of Common Stock owned
by Parent immediately prior to the Effective Time shall automatically be
cancelled and retired and cease to exist, and no consideration or payment shall
be delivered therefor or in respect thereto. All shares of Common Stock to be
converted into Merger Consideration pursuant to this Section 1.2 shall, by
virtue of the Merger and without any action on the part of the holders thereof,
cease to be outstanding, be cancelled and retired and cease to exist, and each
holder of a certificate (representing prior to the Effective Time any such
shares of Common Stock) shall thereafter cease to have any rights with respect
to such shares of Common Stock, except the right to receive (i) the Parent
Shares into which such shares of Common Stock have been converted, (ii) any
dividend and other distributions in accordance with Section 1.3(c) hereof, (iii)
any cash, without interest, to be paid in lieu of any fraction of a Parent Share
in accordance with Section 1.3(d) hereof and (iv) if the Semi Sale has been
consummated, the Semi Sale Consideration.

            (b) CONVERSION OF SHARES OF COMMON STOCK. Subject to Section 1.3(d)
hereof, each share of Common Stock issued and outstanding immediately prior to
the Effective Time (other than shares of Common Stock referred to in the first
sentence of Section 1.2(a) hereof and Dissenting Shares shall, by virtue of the
Merger and without any action on the part of the holder thereof, be converted
into (i) that number of Parent Shares equal to .5427 (provided, however, that
such number was calculated assuming that the Convertible Notes (as defined in
Section 1.5(b) hereof) all are converted prior to the Effective Time), and (ii)
if the Semi Sale (as defined in Section 1.5(a) below) has been consummated at or
prior to the Effective Time, the Semi Sale Consideration (collectively, the
"MERGER CONSIDERATION"); PROVIDED, HOWEVER, in the event that clause (ii)
applies, to the extent that any portion of the Semi Sale Purchase Price is not
paid to the Company or any of its Subsidiaries upon the consummation of the Semi
Sale, then Parent shall only be obligated to pay to the stockholders of the
Company the portion of the Semi Sale Consideration attributable to such portion
of the Semi Sale Purchase Price ("DEFERRED SEMI SALE PURCHASE PRICE") if, as and
when paid by the purchaser of the Semi Business (the "SEMI

                                      -2-
<PAGE>   7

PURCHASER") to Parent, Company or any of its Subsidiaries (less any reserves
established in connection with the principles set forth in Schedule 1.5(a)
hereto).

            (c) DISSENTING SHARES. (i) Notwithstanding any provision of this
Agreement to the contrary, in the event of a Semi Sale, any shares of Company
Common Stock held by a holder who has demanded and perfected dissenters' rights
for such shares in accordance with the DGCL and who, as of the Effective Time,
has not effectively withdrawn or lost such dissenters' rights ("DISSENTING
SHARES") shall not be converted into or represent a right to receive Merger
Consideration pursuant to Section 1.2(b), but the holder thereof shall only be
entitled to such rights as are granted by the DGCL.

                (ii) Notwithstanding the provisions of subsection (i) above, if
any holder of shares of Company Common Stock who demands purchase of such shares
under the DGCL shall effectively withdraw or lose (through failure to perfect or
otherwise) such holder's dissenters' rights, then, as of the later of (A) the
Effective Time or (B) the occurrence of such event, such holder's shares shall
automatically be converted into and represent only the right to receive Merger
Consideration as provided in Section 1.2(b), without interest thereon, upon
surrender of the certificate representing such shares.

                (iii) The Company shall give Parent (A) prompt notice of its
receipt of any written demands for purchase of any shares of Company Common
Stock, withdrawals of such demands, and any other instruments relating to the
Merger served pursuant to the DGCL and received by the Company and (B) the
opportunity to participate in all negotiations and proceedings with respect to
demands for purchase of any shares of Company Common Stock under the DGCL. The
Company shall not, except with the prior written consent of Parent or as may be
required under applicable law, voluntarily make any payment with respect to any
demands for the purchase of Company Common Stock or offer to settle or settle
any such demands.

            (d) CONVERTIBLE NOTES. At the Effective Time, the holders of the
Convertible Notes then outstanding will become entitled thereafter to convert
such Convertible Notes into the kind and amount of Merger Consideration which
they would have been entitled to receive in the Merger had such Convertible
Notes been converted into Common Stock immediately prior to the Merger. At or
prior to the Effective Time, Parent and the Company shall execute any
supplemental indenture required in connection with the Merger by the indenture
governing the Convertible Notes.

        SECTION 1.3 EXCHANGE OF CERTIFICATES.

            (a) Prior to the mailing of the Proxy Statement (as defined in
Section 5.3(c) hereof) such bank, trust company, Person or Persons as shall be
designated by Parent and reasonably acceptable to the Company shall act as the
depositary and exchange agent for the delivery of the Merger Consideration in
exchange for shares of Common Stock (the "EXCHANGE AGENT") in

                                      -3-
<PAGE>   8

connection with the Merger. At or promptly following the Effective Time, Parent
shall deposit, or cause to be deposited, with the Exchange Agent the Merger
Consideration for the benefit of the holders of shares of Common Stock which are
converted into Merger Consideration pursuant to Section 1.2(b) hereof (together
with cash as required to (i) pay any dividends or distributions with respect
thereto in accordance with Section 1.3(c) hereof and (ii) make payments in lieu
of fractional Parent Shares, pursuant to Section 1.3(d) hereof, being
hereinafter referred to as the "EXCHANGE FUND")); PROVIDED, HOWEVER, that Parent
shall only be obligated to so deposit Deferred Semi Sale Purchase Price if, as
and when paid by the Semi Purchaser. For purposes of this Agreement, "PERSON"
means any natural person, firm, individual, corporation, limited liability
company, partnership, association, joint venture, company, business trust, trust
or any other entity or organization, whether incorporated or unincorporated,
including a government or political subdivision or any agency or instrumentality
thereof.

            (b) As of or promptly following the Effective Time, the Surviving
Corporation shall cause the Exchange Agent to mail (and to make available for
collection by hand) to each holder of record of a certificate or certificates,
which immediately prior to the Effective Time represented outstanding shares of
Common Stock (other than Dissenting Shares) (the "CERTIFICATES"), (i) a letter
of transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon proper delivery of the
Certificates to the Exchange Agent and which shall be in the form and have such
other provisions as Parent and the Company may reasonably specify) and (ii)
instructions for use in effecting the surrender of the Certificates in exchange
for the Merger Consideration into which the number of shares of Common Stock
previously represented by such Certificate shall have been converted pursuant to
this Agreement (which instructions shall provide that at the election of the
surrendering holder, Certificates may be surrendered, and the Merger
Consideration in exchange therefor collected, by hand delivery). Upon surrender
of a Certificate for cancellation to the Exchange Agent, together with a letter
of transmittal duly completed and validly executed in accordance with the
instructions thereto, and such other documents as may be required pursuant to
such instructions, the holder of such Certificate shall be entitled to receive
in exchange therefor the Merger Consideration for each share of Common Stock
formerly represented by such Certificate, to be mailed (or made available for
collection by hand if so elected by the surrendering holder) within three
business days of receipt thereof (but in no case prior to the Effective Time),
and the Certificate so surrendered shall be forthwith cancelled. The Exchange
Agent shall accept such Certificates upon compliance with such reasonable terms
and conditions as the Exchange Agent may impose to effect an orderly exchange
thereof in accordance with normal exchange practices. No interest shall be paid
or accrued for the benefit of holders of the Certificates on the cash payable
pursuant to subsections (c) and (d) below upon the surrender of the
Certificates.

            (c) No dividends or other distributions with respect to Parent
Shares with a record date on or after the Effective Time shall be paid to the
holder of any unsurrendered Certificate with respect to the Parent Shares
represented thereby by reason of the conversion of shares of Common Stock
pursuant to Sections 1.2(b) hereof and no cash payment in lieu of fractional
Parent Shares shall be paid to any such holder pursuant to Section 1.3(d) hereof
until such Certificate is

                                      -4-
<PAGE>   9

surrendered in accordance with this Article I. Subject to the effect of
applicable laws, following surrender of any such Certificate, there shall be
paid, without interest, to the Person in whose name the Parent Shares
representing such securities are registered (i) at the time of such surrender
the amount of any cash payable in lieu of fractional Parent Shares to which such
holder is entitled pursuant to Section 1.3(d) hereof and the proportionate
amount of dividends or other distributions with a record date after the
Effective Time theretofore paid with respect to Parent Shares, and (ii) at the
appropriate payment date or as promptly as practicable thereafter, the
proportionate amount of dividends or other distributions with a record date
after the Effective Time but prior to such surrender and a payment date
subsequent to such surrender payable with respect to such Parent Shares.

            (d) No fraction of a share of Parent Common Stock will be issued by
virtue of the Merger, but in lieu thereof each holder of shares of Common Stock
who would otherwise be entitled to a fraction of a share of Parent Common Stock
(after aggregating all fractional shares of Parent Common Stock that otherwise
would be received by such holder) shall, upon surrender of such holder's
Certificate(s) receive from Parent an amount of cash (rounded to the nearest
whole cent), without interest, equal to the product of (i) such fraction,
multiplied by (ii) the average closing price of Parent Common Stock for the five
(5) trading days immediately preceding the last full trading day prior to the
Effective Time, as reported on the Nasdaq National Market System.

            (e) Any portion of the Exchange Fund which remains undistributed to
the holders of the Certificates for one year after the Effective Time shall be
delivered to Parent, upon demand, and any holders of shares of Common Stock
prior to the Merger who have not theretofore complied with this Article I shall
thereafter look for payment of their claim, as general creditors thereof, only
to Parent for their claim for Parent Shares, any cash without interest, to be
paid, in lieu of any fractional Parent Shares and any dividends or other
distributions with respect to Parent Shares to which such holders may be
entitled.

            (f) None of Parent, the Company or the Exchange Agent shall be
liable to any Person in respect of any Parent Shares held in the Exchange Fund
(and any cash, dividends and other distributions payable in respect thereof)
delivered to a public official pursuant to any applicable abandoned property,
escheat or similar law. If any Certificates shall not have been surrendered
prior to one year after the Effective Time (or immediately prior to such earlier
date on which (i) any Parent Shares, (ii) any cash in lieu of fractional Parent
Shares or (iii) any dividends or distributions with respect to Parent Shares in
respect of such Certificate would otherwise escheat to or become the property of
any Governmental Entity (as defined in Section 3.3(b) hereof)), any such Parent
Shares, cash, dividends or distributions in respect of such Certificate shall,
to the extent permitted by applicable law, become the property of Parent, free
and clear of all claims or interest of any Person previously entitled thereto.

        SECTION 1.4 STOCK OPTIONS.

                                       -5-
<PAGE>   10

        Each option granted to a Continuing Employee (as defined in Section
5.12(a) hereof) to acquire a share of Common Stock, which is outstanding and
unvested immediately prior to the Effective Time ("OPTION"), shall become and
represent an option to purchase the Merger Consideration (a "SUBSTITUTE OPTION")
at an exercise price equal to the exercise price per share of Common Stock
subject to the Option immediately prior to the Effective Time; PROVIDED,
HOWEVER, that in the case of an Option that is intended to qualify as an
incentive stock option under Section 422 of the Code, the conversion formula
shall be adjusted (in lieu of providing for any payment of cash) if necessary to
conform with Section 424(a) of the Code. The parties acknowledge and agree that
the number of Options and the exercise price thereof will be adjusted in
accordance with the terms thereof upon consummation of a Semi Spin (as defined
in Section 1.5(a)) so as to preserve the option value as determined immediately
prior to consummation of the Semi Spin; PROVIDED, HOWEVER, that in the case of
an Option that is intended to qualify as an incentive stock option under Section
422 of the Code, such adjustments shall be made in a manner so that the Option
shall continue to be treated as an incentive stock option under Section 422 of
the Code to the greatest extent allowed by law. After the Effective Time, each
Substitute Option shall be exercisable upon the same terms and conditions as
were applicable to the related Option prior to the Effective Time subject to
accelerated vesting if and to the extent required by the applicable plans as of
the date hereof. In the event of any adjustment to the conversion ratio or
exercise price of any Option, such adjustments shall be made pursuant to the
mutual agreement of Parent and Company prior to the Effective Time. Parent shall
take such corporate action as may be necessary or appropriate to, at or prior to
the Effective Time, file a registration statement on Form S-8 (or any successor
or other appropriate form) with respect to the Parent Shares subject to any
Substitute Options to the extent such registration is required under applicable
law in order for such Parent Shares to be sold without restriction in the United
States, and Parent shall maintain the effectiveness of such registration
statement for so long as such Substitute Options remain outstanding.
Notwithstanding anything to the contrary contained in this Agreement, the
parties agree that (i) all options to acquire shares of Common Stock that are
held by Continuing Employees and that are vested and outstanding immediately
prior to the Effective Time shall be, to the extent not exercised, cancelled on
the Effective Time, and (ii) all options to acquire shares of Common Stock that
are held by Persons who are not Continuing Employees shall be exercised,
converted into Semi (as defined in Section 1.5(a)) or Semi Purchaser (as defined
in Section 1.5(a)) options or otherwise cancelled on or prior to the Effective
Time.

        SECTION 1.5 DISPOSITION OF THE SEMICONDUCTOR BUSINESS

            (a) It is a condition to each party's obligation to consummate the
Merger that, prior to the Effective Time, the Semiconductor Business (as defined
below) either be (i) transferred to the stockholders of the Company by
transferring the Semiconductor Business to a newly formed affiliate of the
Company ("SEMI") and distributing the ownership of Semi to the stockholders of
the Company (such transfer and distribution, the "SEMI SPIN") in a transaction
that is treated as immediately taxable in full to the Company for federal income
tax purposes or (ii) sold by the Company in its entirety (a "SEMI SALE" and,
together with the Semi Spin, a "SEMI

                                       -6-
<PAGE>   11

DISPOSITION") to a purchaser (the "SEMI PURCHASER"). The decision as to whether
and under what terms to implement a Semi Spin or a Semi Sale will be the
Company's; PROVIDED, HOWEVER, that Parent's consent shall be required in
connection with any material deviation from the terms and conditions of a Semi
Sale or a Semi Spin, as applicable, and the terms generally applicable, set
forth on Schedule 1.5(a). In the event the parties hereto disagree as to whether
or not the terms and conditions of a Semi Disposition materially deviate from
the terms and conditions set forth on Schedule 1.5(a) or in the event the
parties hereto disagree on the amount of cash to be reserved for the Semi Sale
Taxes (as defined in Section 1.5(b)), either party shall be entitled to submit
such dispute or disagreement for final and binding determination to a mutually
acceptable third-party arbitrator, such determination to be made within ten (10)
days of the submission to such arbitrator by either party. If the parties are
unable to mutually agree upon an arbitrator within one week of a party's
notification to the other party of its desire to arbitrate such a dispute, then
each party shall have one week to select an arbitrator and such two arbitrators
shall have one week to select a third arbitrator who shall have final authority
to resolve such dispute within ten days of such arbitrator's selection based
upon the terms and conditions set forth on Schedule 1.5(a). The parties shall
share equally in the fees and expenses of such arbitrators, and such fees and
expenses shall be paid by the parties prior to the Effective Time.

            (b) The "SEMICONDUCTOR BUSINESS" shall consist of the assets and
liabilities set forth on Schedule 1.5(b). The "SEMI SALE CONSIDERATION" shall
equal the quotient of (i) the Semi Sale Purchase Price less the sum of (A) all
expenses attributable to the sale of the Semiconductor Business and (B) the Semi
Sale Taxes and (ii) the sum of (a) the number of shares of Common Stock
outstanding immediately prior to consummation of the Semi Sale, (b) the number
of shares of Common Stock underlying options to purchase Common Stock that are
vested immediately prior to consummation of the Semi Sale ("VESTED OPTIONS"),
(c) the number of shares of Common Stock underlying Options not constituting
Vested Options that are issued to Continuing Employees, and (d) the number of
shares of Common Stock underlying the Company's 5 7/8% Convertible Subordinate
Notes ("CONVERTIBLE NOTES") outstanding immediately prior to the consummation of
the Semi Sale. The "SEMI SALE PURCHASE PRICE" shall equal the aggregate purchase
price for the Semiconductor Business payable to the Company or any of its
Subsidiaries in the Semi Sale, including any contingent consideration and any
consideration subject to escrow, holdback or indemnification provisions of the
Semi Sale, but excluding amounts payable with respect to, or reserved for
payment with respect to, options issued to employees of the Semiconductor
Business that are not vested as of the Effective Time. The "SEMI SALE TAXES"
shall equal the income and other Taxes incurred and to be incurred by Parent,
the Company or any affiliates thereof in connection with the Semi Sale and the
distribution of the Semi Sale Consideration pursuant to the Merger. For purposes
of determining the amount of the Semi Sale Taxes that are based on net income,
there shall be deducted from the "amount realized" from the Semi Sale (or
corresponding amount as determined for state, local or foreign income Tax
purposes), without duplication, (i) the tax basis of the cash and other assets
recognized as assets of the Semiconductor Business pursuant to Schedules 1.5(a)
and 1.5(b) (but only to the extent such cash and other assets are transferred to
the Semi Purchaser), (ii) capitalized expenses of the Company that

                                       -7-
<PAGE>   12

both reduce the income tax liability of the Company and are attributable to the
sale within the meaning of clause (i)(A) of the second sentence of this Section
1.5(b), (iii) the amount of any deductions accrued on or prior to the Closing
Date attributable to the exercise of Company options after the date hereof and
on or prior to the Closing Date (provided that deductions that reduce Semi Sale
Taxes pursuant to this paragraph shall not also reduce other Company taxable
income, and assuming for the purposes of this subsection that a "disqualifying
disposition" occurs with respect to 80% of all Company options that are
"incentive stock options" under Section 422 of the Code that are exercised on or
prior to the Closing Date) and (iv) any other currently deductible items of the
Company attributable to the sale within the meaning of clause (i)(A) of the
second sentence of this Section 1.5(b). For purposes of this paragraph, expenses
related to the disposition of Semi incurred or accrued by the end of the Closing
Date shall not be treated as allocated to Semi's tax period beginning on the day
after Closing Date under Treas. Reg. Section 1.1502-76(b)(1)(ii)(B). The Company
and Parent shall mutually determine the amount of the Semi Sale Taxes prior to
the Closing Date. If the Company and Parent fail to reach an agreement within
one (1) week prior to the scheduled Closing Date, either party shall be entitled
to submit the matter to a mutually acceptable third-party arbitrator. If the
parties are unable to mutually agree upon an arbitrator within one (1) week of a
party's notification to the other party of its desire to arbitrate such a
dispute, then each party shall have one (1) week to select an arbitrator and
such two arbitrators shall have ten (10) days to select a third arbitrator who
shall have final authority to resolve such dispute within ten (10) days of such
arbitrator's selection, but before the Closing Date. The parties shall share
equally in the fees and expenses of such arbitrators, and such fees and expenses
shall be paid by the parties prior to the Effective Time.

        SECTION 1.6 LOST CERTIFICATES. If any Certificate shall have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the Person
claiming such Certificate to be lost, stolen or destroyed and, if required by
the Surviving Corporation, the posting by such Person of a bond, in such
reasonable amount as the Surviving Corporation may direct (but consistent with
past practice of the Company), as indemnity against any claim that may be made
against it with respect to such Certificate, the Exchange Agent will issue in
exchange for such lost, stolen or destroyed Certificate the Parent Shares to
which the holder thereof is entitled pursuant to this Article I.

        SECTION 1.7 MERGER CLOSING. Subject to the satisfaction or waiver of the
conditions set forth in Article VI hereof, the closing of the Merger (the
"CLOSING") will take place at 10:00 a.m., California time, on a date to be
specified by the parties hereto, and no later than the second business day after
the satisfaction or waiver of the conditions set forth in Article VI hereof that
are to be satisfied other than on the day of Closing, at the offices of Wilson
Sonsini Goodrich & Rosati, Professional Corporation, 650 Page Mill Road, Palo
Alto, California, unless another time, date or place is agreed to in writing by
the parties hereto (such date, the "CLOSING DATE").

        SECTION 1.8 POSSIBLE ALTERNATIVE STRUCTURE. In the event that Parent or
the Company reasonably determines prior to the Effective Time that (i) there is
a material possibility that the transactions contemplated by this Agreement will
not constitute a "reorganization" within

                                      -8-
<PAGE>   13

the meaning of Section 368(a) of the Code, (ii) there is a material possibility
that the Merger will result in a material corporate level Tax, or (iii) there
are material Tax benefits available if the transactions contemplated by this
Agreement are restructured, such party may request that the structure of the
acquisition of the Company contemplated by this Agreement be altered in a manner
so as to permit (i) the transactions contemplated by this Agreement to qualify
as a reorganization under Section 368 of the Code or a transfer under Section
351 of the Code, (ii) the avoidance of such material corporate-level Tax, or
(iii) the achievement of such Tax benefits as applicable. In any case,
corresponding changes to this Agreement shall be made consistent with such
structure but without any material adverse change in the economic consequences
to Parent, the Company or their respective stockholders.


                                   ARTICLE II

                            THE SURVIVING CORPORATION

        SECTION 2.1 CERTIFICATE OF INCORPORATION. At the Effective Time, the

                                   ARTICLE III

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

        The Company represents and warrants to Parent, subject to such
exceptions as are specifically disclosed in writing in the disclosure letter
supplied by the Company to Parent, which disclosure shall provide an exception
to or otherwise qualify the representations or warranties of Company
specifically referred to in such disclosure and such other representations and
warranties to the extent such disclosure shall reasonably appear to be
applicable to such other representations or warranties (the "COMPANY DISCLOSURE
SCHEDULE") as follows:

        SECTION 3.1 CORPORATE EXISTENCE AND POWER. The Company is a corporation
duly incorporated, validly existing and in good standing under the laws of the
State of Delaware, and has all corporate powers and all governmental licenses,
authorizations, consents and approvals (collectively, "LICENSES") required to
carry on its business as now conducted or presently proposed to be conducted
except for failures to have any such License which would not, in the aggregate,
have a Company Material Adverse Effect (as defined below). The Company is duly
qualified to do business as a foreign corporation and is in good standing in
each jurisdiction where the character of the property owned, leased or operated
by it or the nature of its activities makes such qualification necessary, except
in such jurisdictions where failures to be so qualified would not reasonably be
expected to, in the aggregate, have a Company Material Adverse Effect. As used
herein, the term "COMPANY MATERIAL ADVERSE EFFECT" means a material adverse
effect on the financial condition, business, assets or results of operations of
the Company and its Subsidiaries, taken as a whole (assuming consummation of the
Semi Disposition), PROVIDED, HOWEVER, that in no event shall any effect that
results from (a) the public announcement or pendency of the transactions
contemplated hereby or any actions taken in compliance with this Agreement, (b)
changes affecting the telecommunications equipment industry generally, (c)
changes affecting the United States economy generally, or (d) stockholders class
action litigation arising from allegations of a breach of fiduciary duty
relating to this Agreement, constitute a Company Material Adverse Effect. The
Company has heretofore made available to Parent true and complete copies of the
Certificate of Incorporation and the by-laws of the Company as currently in
effect.

        SECTION 3.2 CORPORATE AUTHORIZATION.

            (a) The Company has the requisite corporate power and authority to
execute and deliver this Agreement and, subject to approval of the Company's
stockholders, as set forth in Section 3.2(b) hereof and as contemplated by
Section 5.3 hereof, to perform its obligations hereunder. The execution and
delivery of this Agreement and the performance of its obligations hereunder have
been duly and validly authorized, and this Agreement has been approved, by the
Board of Directors of the Company and no other corporate proceedings, on the
part of the Company, other than the approval of the Company's stockholders, are
necessary to authorize the execution, delivery and performance of this
Agreement. This Agreement has been duly executed and delivered

                                      -10-
<PAGE>   15

by the Company and constitutes, assuming due authorization, execution and
delivery of this Agreement by Parent, a valid and binding obligation of the
Company, enforceable against the Company in accordance with its terms.

            (b) Under applicable law, the Certificate of Incorporation and the
rules of the NASDAQ, the affirmative vote of the holders of a majority of the
shares of Common Stock outstanding on the record date, established by the Board
of Directors of the Company in accordance with the by-laws of the Company,
applicable law and this Agreement, is the vote required to approve the Merger,
adopt this Agreement and, if applicable, approve the Semi Sale.

        SECTION 3.3 CONSENTS AND APPROVALS; NO VIOLATIONS.

            (a) Neither the execution and delivery of this Agreement nor the
performance by the Company of its obligations hereunder will (i) conflict with
or result in any breach of any provision of the Certificate of Incorporation or
the by-laws of the Company; (ii) result in a violation or breach of, or
constitute (with or without due notice or lapse of time or both) a default (or
give rise to any right of termination, cancellation or acceleration or
obligation to repurchase, repay, redeem or acquire or any similar right or
obligation) under any of the terms, conditions or provisions of any note,
mortgage, letter of credit, other evidence of indebtedness, guarantee, license,
lease or agreement or similar instrument or obligation to which the Company or
any of its Subsidiaries is a party or by which any of them or any of their
assets may be bound or (iii) assuming that the filings, registrations,
notifications, authorizations, consents and approvals referred to in subsection
(b) below have been obtained or made, as the case may be, violate any order,
injunction, decree, statute, rule or regulation of any Governmental Entity to
which the Company or any of its Subsidiaries is subject, excluding from the
foregoing clauses (ii) and (iii) such requirements, defaults, breaches, rights
or violations that would not, in the aggregate, reasonably be expected to have a
Company Material Adverse Effect and would not have a material adverse effect on
the ability of the Company to perform its obligations hereunder.

            (b) No filing or registration with, notification to, or
authorization, consent or approval of, any government or any agency, court,
tribunal, commission, board, bureau, department, political subdivision or other
instrumentality of any government (including any regulatory or administrative
agency), whether federal, state, multinational (including, but not limited to,
the European Community), provincial, municipal, domestic or foreign (each, a
"GOVERNMENTAL ENTITY") is required in connection with the execution and delivery
of this Agreement by the Company or the performance by the Company of its
obligations hereunder, except (i) the filing of the Certificate of Merger in
accordance with the DGCL; (ii) compliance with any applicable requirements of
the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the
rules and regulations thereunder (the "HSR ACT"), or any foreign laws regulating
competition, antitrust, investment or exchange controls; (iii) compliance with
any applicable requirements of the Securities Act of 1933, as amended, and the
rules and regulations

                                      -11-
<PAGE>   16

thereunder (the "SECURITIES ACT") and the Securities Exchange Act of 1934, as
amended, and the rules and regulations thereunder (the "EXCHANGE ACT"); (iv)
compliance with any applicable requirements of state blue sky or takeover laws
and (v) such other consents, approvals, orders, authorizations, notifications,
registrations, declarations and filings the failure of which to be obtained or
made would not, in the aggregate, reasonably be expected to have a Company
Material Adverse Effect and would not have a material adverse effect on the
ability of the Company to perform its obligations hereunder.

        SECTION 3.4 CAPITALIZATION. The authorized capital stock of the Company
consists of 150,000,000 shares of Common Stock, par value $0.001 and 5,000,000
shares of preferred stock, par value $ 0.001 per share, of the Company (the
"PREFERRED STOCK"). As of September 30, 1999, there were (i) 40,476,647 shares
of Common Stock issued and outstanding and (ii) no shares of Preferred Stock
issued and outstanding. All shares of capital stock of the Company have been
duly authorized and validly issued and are fully paid and nonassessable and were
not issued in violation of any preemptive rights. As of September, 30, 1999,
there were outstanding options to purchase 14,475,268 shares of Common Stock.
Except as set forth in this Section 3.4, for the Convertible Notes and for
changes since September 30, 1999, resulting from the exercise of options
outstanding on such date, there are outstanding (i) no shares of capital stock
or other voting securities of the Company, (ii) no securities of the Company or
any Subsidiary of the Company convertible into or exchangeable for shares of
capital stock or voting securities of the Company, (iii) no options, preemptive
or other rights to acquire from the Company or any of its Subsidiaries, and no
obligation of the Company to issue, any capital stock, voting securities or
securities convertible into or exchangeable for capital stock or voting
securities of the Company and (iv) no equity equivalent interest in the
ownership or earnings of the Company or its Subsidiaries or other similar rights
(the items in clauses (i), (ii), (iii) and (iv) being referred to collectively
as the "COMPANY SECURITIES"). There are no outstanding obligations of the
Company or any of its Subsidiaries to repurchase, redeem or otherwise acquire
any Company Securities. No Subsidiary of the Company owns any capital stock or
other voting securities of the Company.

        SECTION 3.5 SUBSIDIARIES.

            (a) Each Subsidiary of the Company (each, a "COMPANY SUBSIDIARY")
(i) is a corporation duly incorporated, validly existing and in good standing
under the laws of its jurisdiction of incorporation, (ii) has all corporate
powers and all material governmental licenses, authorizations, consents and
approvals required to carry on its business as now conducted and (iii) is duly
qualified to do business as a foreign corporation and is in good standing in
each jurisdiction where the character of the property owned or leased by it or
the nature of its activities makes such qualification necessary, except for
failures of this representation and warranty to be true which would not, in the
aggregate, have a Company Material Adverse Effect. For purposes of this
Agreement, "SUBSIDIARY" means with respect to any Person, any corporation or
other legal entity of which such Person owns, directly or indirectly, more than
50% of the outstanding stock or other equity interests, the holders of which are
entitled to vote for the election of the board of directors or other governing
body of such corporation or other legal entity. All Active Company Subsidiaries

their respective jurisdictions of incorporation are identified in Schedule 3.5
of the Company Disclosure Schedule.

            (b) All of the outstanding shares of capital stock of each
Subsidiary of the Company are duly authorized, validly issued, fully paid and
nonassessable, and such shares are owned by the Company or by a Subsidiary of
the Company free and clear of any Liens (as defined hereafter) or limitations on
voting rights. There are no subscriptions, options, warrants, calls, preemptive
rights, rights, convertible securities or other agreements or commitments of any
character relating to the issuance, transfer, sale, delivery, voting or
redemption (including any rights of conversion or exchange under any outstanding
security or other instrument) of any of the capital stock or other equity
interests of any of such Subsidiaries. There are no agreements requiring the
Company or any of its Subsidiaries to make contributions to the capital of, or
lend or advance funds to, any Subsidiaries of the Company. For purposes of this
Agreement, "LIEN" means, with respect to any asset, any mortgage, lien, pledge,

dates, and giving effect to any amendments thereto, (a) the Company SEC
Documents complied in all material respects with the requirements of the
Securities Act or the Exchange Act, as the case may be, and the applicable rules
and regulations of the SEC promulgated thereunder and (b) none of the Company
SEC Documents contained any untrue statement of a material fact or omitted to

since the date of the most recent consolidated balance sheet included in the

that is subject to the laws of any jurisdiction outside the United States,
Schedule 3.12(a) of the Company Disclosure Schedule contains a true and complete
list of each material deferred compensation, incentive compensation, and equity
compensation plan; material "welfare" plan, fund or program (within the meaning

of section 3(2) of ERISA); each material employment, termination or severance
agreement; and each other material employee benefit plan, fund, program,
agreement or arrangement, in each case, that is in writing and sponsored,
maintained or contributed to or required to be contributed to by the Company or
by any trade or business, whether or not incorporated (each, an "ERISA
AFFILIATE"), that together with the Company would be deemed a "single employer"
within the meaning of section 4001(b) of ERISA, or to which the Company or an
ERISA Affiliate is party, whether written or oral, for the benefit of any
employee, consultant, director or former employee, consultant or director of the
Company or any Subsidiary of the Company. The plans, funds, programs, agreements
and arrangements listed on Schedule 3.12(a) of the Company Disclosure Schedule
are referred to herein collectively as the "PLANS".

            (b) With respect to each Plan, the Company has heretofore delivered
or made available to Parent true and complete copies of the Plan and any
amendments thereto (or if the Plan is not a written Plan, a description
thereof), any related trust or other funding vehicle, the most recent reports or
summaries required under ERISA or the Code and the most recent determination
letter

                                      -17-
<PAGE>   22

received from the Internal Revenue Service with respect to each Plan intended to
qualify under section 401 of the Code.

            (c) No liability under Title IV or section 302 of ERISA has been
incurred by the Company or any ERISA Affiliate that has not been satisfied in
full, other than liability for premiums due the Pension Benefit Guaranty
Corporation (which premiums have been paid when due).

            (d) Each Plan has been operated and administered in all material
respects in accordance with its terms and applicable law, including, but not
limited to, ERISA and the Code.

            (e) Each Plan intended to be "qualified" within the meaning of
section 401(a) of the Code has received a favorable determination letter from
the Internal Revenue Service, or in the case of such a Plan for which a
favorable determination letter has not yet been received, the applicable
remedial amendment period under Section 401(b) of the Code has not expired.

            (f) No Plan provides medical, surgical, hospitalization, death or
similar benefits (whether or not insured) for employees or former employees of
the Company or any Subsidiary for periods extending beyond their retirement or
other termination of service, other than (i) coverage mandated by applicable
law, (ii) death benefits under any "pension plan," or (iii) benefits the full
cost of which is borne by the current or former employee (or his or her
beneficiary), dependant or other covered person.

            (g) There are no pending, or to the knowledge of the Company,
threatened or anticipated, claims that would reasonably be expected to have a
Company Material Adverse Effect by or on behalf of any Plan, by any employee or
beneficiary covered under any such Plan, or otherwise involving any such Plan
(other than routine claims for benefits).

            (h) The consummation of the transactions contemplated by this
Agreement will not, either alone or in combination with another event, (i)
entitle any current or former employee or officer of the Company or any ERISA
Affiliate to severance pay, unemployment compensation or any other payment,
except as expressly provided in this Agreement, or (ii) accelerate the time of
payment or vesting, or increase the amount of compensation due any such employee
or officer, other than payments, accelerations or increases (x) under any
employee benefit plan that is subject to the laws of a jurisdiction outside of
the United States or (y) mandated by applicable law.

            (i) To the knowledge of the Company, all employee benefit plans that
are subject to the laws of any jurisdiction outside the United States are in
material compliance with such applicable laws, including relevant Tax laws, and
the requirements of any trust deed under which they were established, except for
such exceptions to the foregoing which, in the aggregate, would not reasonably
be expected to have a Company Material Adverse Effect. Schedule 3.12(i) lists
all material employee pension benefit plans that are subject to the laws of any
jurisdiction outside the United States except for such plans that are
governmental or statutory plans.

                                      -18-
<PAGE>   23

            (j) Each Plan can be amended prospectively or terminated at any time
without approval from any person, without advance notice, and without any
liability other than for benefits accrued prior to such amendment or
termination.

            (k) No agreement, commitment, or obligation exists to increase any
benefits under any Plan or to adopt any new Plan.

            (l) No Plan has any unfunded accrued benefits that are not fully
reflected in the Financial Statements.

            (m) No ERISA pension plan has incurred any "accumulated funding
deficiency" or "waived funding deficiency" within the meaning of Section 302 of
ERISA or Section 412 of the Internal Revenue Code of 1986, as amended (the
"CODE") and the Company has never sought to obtain any variance from the minimum
funding standards pursuant to Section 412(d) of the Code. The funding method
used in connection with each ERISA Pension Plan meets the requirements of ERISA
and the Code and the actuarial assumptions used in connection with each such
plan are reasonable, given the experience of such ERISA Pension Plan and
reasonable expectations.

            The fair market value of the plan assets of each ERISA Pension Plan
are at least equal to (i) the present value of its benefit liabilities (as
defined in ERISA Section 4001(a)(16) , including any unpredictable contingent
event benefits within the meaning of Code Section 412(l)(7), and determined on
the basis of assumptions prescribed by the PBGC for purposes of ERISA Section
4044), and (ii) the Projected Benefit Obligations thereunder, as defined in
Statement of Financial Accounting Standards No. 87, including any allowance for
indexation and ad hoc increases. No ERISA Pension Plan has been completely or
partially terminated or been the subject of a Reportable Event under ERISA
Section 4043. No proceeding by the PBGC to terminate any ERISA Pension Plan has
been instituted, and the Company has not incurred any liability to the PBGC
(other than the PBGC premiums, all of which have been timely paid) or otherwise
under Title IV of ERISA with respect to any ERISA Pension Plan.

            (n) The Company neither maintains nor participates in any Voluntary
Employees' Beneficiary Association ("VEBA"), under Code Sections 419 and 419A,
which is intended to be exempt from taxation under section 501(c)(9) of the
Code.

            (o) The Company does not maintain, participate in, contribute to, or
have any obligation to contribute or any liability with respect to any multiple
employer or multiemployer plan, or has had any obligation with respect to such a
plan during the six years immediately preceding the date of this Agreement.

applicable laws, ordinances, rules and regulations of any federal, state, local
or foreign governmental authority applicable to their respective businesses and

not reasonably be expected to have a Company Material Adverse Effect. All
governmental approvals, permits and licenses (collectively, "PERMITS") required
to conduct the business of the Company and its Subsidiaries have been obtained,

knowledge of the Company, no union organizing campaign with respect to the
Company's employees or any of its Subsidiaries is underway; (iii) there is no

of the Company or any of its Subsidiaries, except for such exceptions to the
foregoing clauses (i) through (vi) which, individually or in the aggregate,
would not reasonably be expected to have a Company Material Adverse Effect.

        SECTION 3.15 CERTAIN CONTRACTS AND ARRANGEMENTS. Each material contract
or agreement to which the Company or any of its Subsidiaries is a party or by
which any of them is bound is in full force and effect, and neither the Company
nor any of its Subsidiaries, nor, to the knowledge of the Company, any other
party thereto, is in breach of, or default under, any such contract or
agreement, and no event has occurred that with notice or passage of time or both
would constitute such a breach or default thereunder by the Company or any of
its Subsidiaries, or, to the knowledge of the Company, any other party thereto,
except for such failures to be in full force and effect and such breaches and
defaults which, in the aggregate, would not reasonably be expected to have a
Company Material Adverse Effect.

                    REPRESENTATIONS AND WARRANTIES OF PARENT

        Parent represents and warrants to the Company subject to such exceptions
as are specifically disclosed in writing in the disclosure letter and
referencing a specific representation supplied by Parent to Company, which
disclosure shall provide an exception to or otherwise qualify the
representations or warranties of Parent specifically referred to in such
disclosure and such other representations and warranties to the extent such
disclosure shall reasonably appear to be applicable to such other
representations or warranties (the "PARENT DISCLOSURE SCHEDULE"), as follows:

                                      -24-
<PAGE>   29

        SECTION 4.1 CORPORATE EXISTENCE AND POWER. Parent is a corporation duly
incorporated (or other entity duly organized), validly existing and in good
standing under the laws of its jurisdiction of incorporation, has all corporate
or other power, as the case may be, and all Licenses required to carry on its
business as now conducted or presently proposed to be conducted except for
failures to have any such License which would not, in the aggregate, have a
Parent Material Adverse Effect (as defined below). Parent is duly qualified to
do business and is in good standing in each jurisdiction where the character of
the property owned, leased or operated by it or the nature of its activities
makes such qualification necessary, except for those jurisdictions where
failures to be so qualified would not reasonably be expected to, in the
aggregate, have a Parent Material Adverse Effect. As used herein, the term
"PARENT MATERIAL ADVERSE EFFECT" means a material adverse effect on the
financial condition, business, assets or results of operations of Parent and its
Subsidiaries, taken as a whole, PROVIDED, HOWEVER, that in no event shall any
effect that results from (a) the public announcement or pendency of the
transactions contemplated hereby, (b) changes affecting the telecommunications
equipment industry generally, (c) changes affecting the United States economy
generally or (d) stockholder class action litigation arising from allegations of
a breach of fiduciary duty relating to this Agreement, constitute a Parent
Material Adverse Effect. Parent has heretofore delivered or made available to
the Company true and complete copies of the governing documents or other
organizational documents of like import, as currently in effect, of Parent.

        SECTION 4.2 AUTHORIZATION. Parent has the requisite power and authority
to execute and deliver this Agreement and to perform its obligations hereunder.
The execution and delivery of this Agreement and the performance of its
obligations hereunder have been duly and validly authorized by the Board of
Directors of Parent, and no other proceedings on the part of Parent are
necessary to authorize the execution, delivery and performance of this
Agreement. This Agreement has been duly executed and delivered by Parent and
constitutes, assuming due authorization, execution and delivery of this
Agreement by the Company, a valid and binding obligation of Parent, enforceable
against it in accordance with its terms.

        SECTION 4.3 CONSENTS AND APPROVALS; NO VIOLATIONS.

            (a) Neither the execution and delivery of this Agreement nor the
performance by Parent of its obligations hereunder will (i) conflict with or
result in any breach of any provision of the certificate of incorporation or
by-laws (or other governing or organizational documents) of Parent, or (ii)
result in a violation or breach of, or constitute (with or without due notice or
lapse of time or both) a default (or give rise to any right of termination,
cancellation or acceleration or obligation to repurchase, repay, redeem or
acquire or any similar right or obligation) under any of the terms, conditions
or provisions of any note, mortgage, letter of credit, other evidence of
indebtedness, guarantee, license, lease or agreement or similar instrument or
obligation to which Parent is a party or by which any of them or any of the
respective assets used or held for use by any of them may be bound or (iii)
assuming that the filings, registrations, notifications, authorizations,
consents and approvals referred to in subsection (b) below have been obtained or
made, as the case

                                      -25-
<PAGE>   30

may be, violate any order, injunction, decree, statute, rule or regulation of
any Governmental Entity to which Parent is subject, excluding from the foregoing
clauses (ii) and (iii) such requirements, defaults, breaches, rights or
violations that would not, in the aggregate, reasonably be expected to have a
Parent Material Adverse Effect and would not reasonably be expected to have a
material adverse effect on the ability of Parent to consummate the transactions
contemplated hereby.

            (b) No filing or registration with, notification to, or
authorization, consent or approval of, any Governmental Entity is required in
connection with the execution and delivery of this Agreement by Parent or the
performance by it of its obligations hereunder, except (i) the filing of the
Certificate of Merger in accordance with the DGCL; (ii) compliance with any
applicable requirements of the HSR Act or any foreign laws regulating
competition, antitrust, investment or exchange controls; (iii) compliance with
any applicable requirements of the Securities Act and the Exchange Act; (iv)
compliance with any applicable requirements of state blue sky or takeover laws
and (v) such other consents, approvals, orders, authorizations, notifications,
registrations, declarations and filings the failure of which to be obtained or
made would not reasonably be expected to have a Parent Material Adverse Effect
and would not have a material adverse effect on the ability of Parent to perform
its obligations hereunder.

        SECTION 4.4 CAPITALIZATION. The authorized capital stock of Parent
consists of 50,000,000 shares of Parent Common Stock and 5,000,000 shares of
preferred stock, par value $.001 per share, of Parent (the "PARENT PREFERRED
STOCK"). As of September 27, 1999 there were (i) 15,145,478 shares of Parent
Common Stock issued and outstanding and (ii) no shares of Parent Preferred Stock
issued and outstanding. All shares of capital stock of Parent have been duly
authorized and validly issued and are fully paid and nonassessable and were not
issued in violation of any preemptive rights. As of September 27, 1999 there
were outstanding Parent Options to purchase 1,910,974 shares of Parent Common
Stock. Except as set forth in this Section 4.4 and except for changes since
September 27, 1999 resulting from the exercise of Parent Options outstanding on
such date, there are outstanding (i) no shares of capital stock or other voting
securities of Parent, (ii) no securities of Parent or any Subsidiary of Parent
convertible into or exchangeable for shares of capital stock or voting
securities of Parent, (iii) no options, preemptive or other rights to acquire
from Parent or any of its Subsidiaries, and no obligation of Parent to issue,
any capital stock, voting securities or securities convertible into or
exchangeable for capital stock or voting securities of Parent, and (iv) no
equity equivalent interest in the ownership or earnings of Parent or its
Subsidiaries or other similar rights (the items in clauses (i), (ii), (iii) and
(iv) being referred to collectively as the "PARENT SECURITIES"). There are no
outstanding obligations of Parent or any of its Subsidiaries to repurchase,
redeem or otherwise acquire any Parent Securities. No Subsidiary of Parent owns
any capital stock or other voting securities of Parent or the Company.

        SECTION 4.5 SUBSIDIARIES.

            (a) Each Subsidiary of Parent (each, a "PARENT SUBSIDIARY") (i) is a
corporation duly incorporated, validly existing and in good standing under the
laws of its jurisdiction

                                      -26-
<PAGE>   31

of incorporation, (ii) has all corporate powers and all material governmental
licenses, authorizations, consents and approvals required to carry on its
business as now conducted and (iii) is duly qualified to do business as a
foreign corporation and is in good standing in each jurisdiction where the
character of the property owned or leased by it or the nature of its activities
makes such qualification necessary, except for failures of this representation
and warranty to be true which would not, in the aggregate, have a Parent
Material Adverse Effect. All Active Parent Subsidiaries and their respective
jurisdictions of incorporation are identified in Schedule 4.5 of Parent
Disclosure Schedule.

            (b) All of the outstanding shares of capital stock of each
Subsidiary of Parent are duly authorized, validly issued, fully paid and
nonassessable, and such shares are owned by Parent or by a Subsidiary of Parent
free and clear of any Liens or limitations on voting rights. There are no
subscriptions, options, warrants, calls, preemptive rights, rights, convertible
securities or other agreements or commitments of any character relating to the
issuance, transfer, sale, delivery, voting or redemption (including any rights
of conversion or exchange under any outstanding security or other instrument) of
any of the capital stock or other equity interests of any of such Subsidiaries.
There are no agreements requiring Parent or any of its Subsidiaries to make
contributions to the capital of, or lend or advance funds to, any Subsidiaries
of Parent.

        SECTION 4.6 SEC DOCUMENTS. Parent has filed all required reports, proxy
statements, registration statements, forms and other documents with the SEC
since January 1, 1998 (the "PARENT SEC DOCUMENTS"). As of their respective
dates, and giving effect to any amendments thereto, (a) the Parent SEC Documents
complied in all material respects with the requirements of the Securities Act or
the Exchange Act, as the case may be, and the applicable rules and regulations
of the SEC promulgated thereunder and (b) none of the Parent SEC Documents
contained any untrue statement of a material fact or omitted to state any
material fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading.

        SECTION 4.7 FINANCIAL STATEMENTS. The financial statements of Parent
(including, in each case, any notes and schedules thereto) included in the
Parent SEC Documents (a) were prepared from the books and records of Parent and
its Subsidiaries, (b) comply as to form in all material respects with all
applicable accounting requirements and the rules and regulations of the SEC with

regulations of the SEC) and (d) fairly present, in all material respects, the
consolidated financial position of Parent and its consolidated Subsidiaries as
of the dates thereof and the consolidated results of their operations and cash
flows for the periods then ended (subject, in the case of unaudited statements,
to normal year-end audit adjustments which were not and are not expected to be,
individually or in the aggregate, material in amount).

        SECTION 4.8 ABSENCE OF UNDISCLOSED LIABILITIES. Except as set forth in
the Parent SEC Documents filed through the date of this Agreement, and except
for liabilities and

                                      -27-
<PAGE>   32

obligations incurred in the ordinary course of business since the date of the
most recent consolidated balance sheet included in the Parent SEC Documents,
neither Parent nor any of its Subsidiaries has any liabilities or obligations of
any nature (whether accrued, absolute, contingent or otherwise) except for those
that would not, in the aggregate, reasonably be expected to have a Parent
Material Adverse Effect.

        SECTION 4.9 PROXY STATEMENT; FORM S-4.

            (a) None of the information contained in the Proxy Statement (and
any amendments thereof or supplements thereto) will at the time of the mailing
of the Proxy Statement to the stockholders of the Company or the stockholders of
Parent and at the time of the Special Meeting or the Parent Special Meeting,
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading, except that no representation is made by Parent with respect to
statements made or omitted in the Proxy Statement relating to the Company based
on information supplied by the Company for inclusion in the Proxy Statement. The
Proxy Statement will comply as to form in all material respects with the
provisions of the Exchange Act and the rules and regulations promulgated
thereunder, except that no representation is made by Parent with respect to the
statements made or omitted in the Proxy Statement relating to the Company based
on information supplied by the Company for inclusion in the Proxy Statement.

            (b) None of the information supplied or to be supplied by Parent for
inclusion or incorporation by reference in the Form S-4 will, with respect to
information relating to Parent, at the time the Form S-4 is filed with the SEC,
and at any time it is amended or supplemented or at the time it becomes
effective under the Securities Act, contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading.

            (e) issuance of Parent Securities other than pursuant to options
outstanding as of June 30, 1999 and the issuance of options after such date in
the ordinary course of business (and the issuance of securities pursuant

            (f) acquisition or disposition of assets material to Parent and its
Subsidiaries, except for sales of inventory in the ordinary course of business

        (1) All Tax Returns required to be filed by or on behalf of Parent, each
of its Subsidiaries, and each affiliated, combined, consolidated or unitary
group of which Parent or any of its Subsidiaries is or has been a member
("PARENT GROUP MEMBERS") have been timely filed, and all returns filed are
complete and accurate and correctly reflect the tax liabilities required to be
reported therein, (2) Parent, its Subsidiaries and Parent Group Members have

have adequately reserved for in accordance with GAAP all Taxes (whether or not
shown on any Tax Return) that have accrued but are not yet due or payable; (3)
there is no presently pending audit examination, refund claim or litigation,
proposed adjustment or matter in controversy with respect to any Taxes due and
owing by Parent, any Subsidiary of Parent or any Parent Group Member and none of
the above has knowledge that of any such action or proceeding is being

Parent Group Member has complied in all material respects with all rules and
regulations relating to the withholding of Taxes.

        SECTION 4.12 EMPLOYEE BENEFIT PLANS.

            (a) Except for any plan, fund, program, agreement or arrangement
that is subject to the laws of any jurisdiction outside the United States,
Schedule 4.12(a) of Parent Disclosure Schedule contains a true and complete list
of each material deferred compensation, incentive compensation, and equity
compensation plan; material "welfare" plan, fund or program (within the meaning
of section 3(1) of ERISA); material "pension" plan, fund or program (within the
meaning of section 3(2) of ERISA); each material employment, termination or
severance agreement; and each other material employee benefit plan, fund,
program, agreement or arrangement, in each case, that is in writing and
sponsored, maintained or contributed to or required to be contributed to by
Parent or by any trade or business, whether or not incorporated, that together
with Parent would be deemed a "single employer" within the meaning of section
4001(b) of ERISA, or to which Parent or an ERISA Affiliate is party, whether
written or oral, for the benefit of any employee, consultant, director or former
employee, consultant or director of Parent or any Subsidiary of Parent. The
plans, funds, programs, agreements and arrangements listed on Schedule 4.12(a)
of the Parent Disclosure Schedule are referred to herein collectively as the
"PARENT PLANS".

            (b) With respect to each Parent Plan, Parent has heretofore
delivered or made available to the Company true and complete copies of the
Parent Plan and any amendments thereto (or if the Parent Plan is not a written
plan, a description thereof), any related trust or other funding vehicle, the
most recent reports or summaries required under ERISA or the Code and the most
recent determination letter received from the Internal Revenue Service with
respect to each Parent Plan intended to qualify under section 401 of the Code.

            (c) No liability under Title IV or section 302 of ERISA has been
incurred by Parent or any ERISA Affiliate that has not been satisfied in full,
other than liability for premiums due the Pension Benefit Guaranty Corporation
(which premiums have been paid when due).

            (d) Each Parent Plan has been operated and administered in all
material respects in accordance with its terms and applicable law, including,
but not limited to, ERISA and the Code.

            (e) Each Parent Plan intended to be "qualified" within the meaning
of section 401(a) of the Code has received a favorable determination letter from
the Internal Revenue Service, or in the case of such a Parent Plan for which a
favorable determination letter has not yet been

                                      -30-
<PAGE>   35


received, the applicable remedial amendment period under Section 401(b) of the
Code has not expired.

            (f) No Parent Plan provides medical, surgical, hospitalization,
death or similar benefits (whether or not insured) for employees or former
employees of Parent or any Subsidiary for periods extending beyond their
retirement or other termination of service, other than (i) coverage mandated by
applicable law, (ii) death benefits under any "pension plan," or (iii) benefits
the full cost of which is borne by the current or former employee (or his or her
beneficiary), dependant or other covered person.

            (g) There are no pending, or to the knowledge of Parent, threatened
or anticipated, claims that would reasonably be expected to have a Parent
Material Adverse Effect by or on behalf of any Parent Plan, by any employee or
beneficiary covered under any such Parent Plan, or otherwise involving any such
Parent Plan (other than routine claims for benefits).

            (h) To the knowledge of Parent, all employee benefit plans that are
subject to the laws of any jurisdiction outside the United States are in
material compliance with such applicable laws, including relevant Tax laws, and
the requirements of any trust deed under which they were established, except for
such exceptions to the foregoing which, in the aggregate, would not reasonably
be expected to have a Parent Material Adverse Effect. Schedule 4.12(i) lists all
material employee pension benefit plans that are subject to the laws of any
jurisdiction outside the United States except for such plans that are
governmental or statutory plans.

            (i) Each Plan can be amended prospectively or terminated at any time
without approval from any person, without advance notice, and without any
liability other than for benefits accrued prior to such amendment or
termination.

            (j) No agreement, commitment, or obligation exists to increase any
benefits under any Plan or to adopt any new Plan.

            (k) No Plan has any unfunded accrued benefits that are not fully
reflected in the Financial Statements.

            (l) No ERISA pension plan has incurred any "accumulated funding
deficiency" or "waived funding deficiency" within the meaning of Section 302 of
ERISA or Section 412 of the Internal Revenue Code of 1986, as amended (the
"Code") and Parent has never sought to obtain any variance from the minimum
funding standards pursuant to Section 412(d) of the Code. The funding method
used in connection with each ERISA Pension Plan meets the requirements of ERISA
and the Code and the actuarial assumptions used in connection with each such
plan are reasonable, given the experience of such ERISA Pension Plan and
reasonable expectations.

            The fair market value of the plan assets of each ERISA Pension Plan
are at least equal to (i) the present value of its benefit liabilities (as
defined in ERISA Section 4001(a)(16), including

                                      -31-
<PAGE>   36

any unpredictable contingent event benefits within the meaning of Code Section
412(l)(7), and determined on the basis of assumptions prescribed by the PBGC for
purposes of ERISA Section 4044), and (ii) the Projected Benefit Obligations
thereunder, as defined in Statement of Financial Accounting Standards No. 87,
including any allowance for indexation and ad hoc increases. No ERISA Pension
Plan has been completely or partially terminated or been the subject of a
Reportable Event under ERISA Section 4043. No proceeding by the PBGC to
terminate any ERISA Pension Plan has been instituted, and Parent has not
incurred any liability to the PBGC (other than the PBGC premiums, all of which
have been timely paid) or otherwise under Title IV of ERISA with respect to any
ERISA Pension Plan.

            (m) Parent neither maintains nor participates in any Voluntary
Employees' Beneficiary Association ("VEBA"), under Code Sections 419 and 419A,
which is intended to be exempt from taxation under section 501(c)(9) of the
Code.

            (n) Parent does not maintain, participate in, contribute to, or have
any obligation to contribute or any liability with respect to any multiple
employer or multiemployer plan, or has had any obligation with respect to such a
plan during the six years immediately preceding the date of this Agreement.

        SECTION 4.13 LITIGATION; COMPLIANCE WITH LAWS.

            (a) Except as set forth in either the Parent SEC Documents filed
through the date of this Agreement or otherwise fully covered by insurance,
there is no action, suit or proceeding pending against, or to the knowledge of
Parent threatened against, Parent or any Subsidiary of Parent or any of their
respective properties before any court or arbitrator or any Governmental Entity
which would reasonably be expected to have a Parent Material Adverse Effect.

            (b) Parent and its Subsidiaries are in compliance with all
applicable laws, ordinances, rules and regulations of any federal, state, local
or foreign governmental authority applicable to their respective businesses and
operations, except for such violations, if any, which, in the aggregate, would
not reasonably be expected to have a Parent Material Adverse Effect. All Permits
required to conduct the business of Parent and its Subsidiaries have been
obtained, are in full force and effect and are being complied with except for
such violations and failures to have Permits in full force and effect, if any,
which, individually or in the aggregate, would not reasonably be expected to
have a Parent Material Adverse Effect.

        SECTION 4.14 LABOR MATTERS. As of the date of this Agreement (i) there
is no labor strike, dispute, slowdown, stoppage or lockout actually pending or,
to the knowledge of Parent, threatened against Parent; (ii) to the knowledge of
Parent, no union organizing campaign with respect to Parent's employees is
underway; (iii) there is no unfair labor practice charge or complaint against
Parent pending or, to the knowledge of Parent, threatened before the National
Labor Relations Board or any similar state or foreign agency; (iv) there is no
written grievance pending

                                      -32-
<PAGE>   37

relating to any collective bargaining agreement or other grievance procedure;
(v) to the knowledge of Parent, no charges with respect to or relating to Parent
are pending before the Equal Employment Opportunity Commission or any other
agency responsible for the prevention of unlawful employment practices; and (vi)
there are no collective bargaining agreements with any union covering employees
of Parent, except for such exceptions to the foregoing clauses (i) through (vi)
which, individually or in the aggregate, would not reasonably be expected to
have a Parent Material Adverse Effect.

        SECTION 4.15 CERTAIN CONTRACTS AND ARRANGEMENTS. Each material contract
or agreement to which Parent or any of its Subsidiaries is a party or by which
any of them is bound is in full force and effect, and neither Parent nor any of
its Subsidiaries, nor, to the knowledge of Parent, any other party thereto, is
in breach of, or default under, any such contract or agreement, and no event has
occurred that with notice or passage of time or both would constitute such a
breach or default thereunder by Parent or any of its Subsidiaries, or, to the
knowledge of Parent, any other party thereto, except for such failures to be in
full force and effect and such breaches and defaults which, in the aggregate,
would not reasonably be expected to have a Parent Material Adverse Effect.

        SECTION 4.16 ENVIRONMENTAL MATTERS.

            (a) (i) To the knowledge of Parent, Parent and its Subsidiaries are
in compliance with all applicable Environmental Laws (which compliance includes,
but is not limited to, the possession by Parent and its Subsidiaries of all
permits and other governmental authorizations required under applicable
Environmental Laws, and compliance with the terms and conditions thereof),
except where failures to be in compliance would not, in the aggregate,
reasonably be expected to have a Parent Material Adverse Effect. Since January
1, 1998 and prior to the date of this Agreement, neither Parent nor any of its
Subsidiaries has received any communication (written or oral), whether from a
Governmental Entity, citizens' group, employee or otherwise, alleging that
Parent or any of its Subsidiaries is not in such compliance, except where
failures to be in compliance would not, in the aggregate, reasonably be expected
to have a Parent Material Adverse Effect.

                (ii) There is no Environmental Claim pending or, to the
knowledge of Parent, threatened against Parent or any of its Subsidiaries or, to
the knowledge of Parent, against any Person whose liability for any
Environmental Claim Parent or any of its Subsidiaries has or may have retained
or assumed either contractually or by operation of law that would reasonably be
expected to have a Parent Material Adverse Effect.

                (iii) There are no present or, to the knowledge of Parent, past
actions, activities, circumstances, conditions, events or incidents, including,
without limitation, the Release or presence of any Hazardous Material that could
form the basis of any Environmental Claim against Parent or any of its
Subsidiaries or, to the knowledge of Parent, against any Person whose liability
for any Environmental Claim Parent or any of its Subsidiaries has or may have
retained or assumed

                                      -33-
<PAGE>   38

either contractually or by operation of law that would, individually or in the
aggregate, reasonably be expected to have a Parent Material Adverse Effect.

                (iv) Neither the Parent nor any of its Subsidiaries is subject
to any indemnity or other agreement relating to liability under any
Environmental Laws or relating to Hazardous Materials.

        SECTION 4.17 INTELLECTUAL PROPERTY.

            (a) To the knowledge of Parent, Parent and its Subsidiaries own or
have the right to use all material Intellectual Property reasonably necessary
for Parent and its Subsidiaries to conduct their business as it is currently
conducted.

            (b) To the knowledge of Parent: (i) all of the registrations,
including patent, relating to material Intellectual Property owned by Parent and
its Subsidiaries are subsisting and unexpired, free of all liens or
encumbrances, have not been abandoned; (ii) Parent does not infringe the
intellectual property rights of any third party in any respect that would

Effect; and (iv) Parent has not received notice of any pending or threatened
suit, action or adversarial proceeding that seeks to limit, cancel or question

            (c) To the knowledge of the Parent, the Parent and its Subsidiaries
have not used and are not making use of any confidential or proprietary
information or trade secrets of any other Person in breach of any agreement to
which the Parent is subject or in violation of any civil or criminal law.

to have the Form S-4 declared effective under the Securities Act as promptly as
practicable after such filing. The Company will use commercially reasonable
efforts to cause the Proxy Statement to be mailed to the Company's stockholders,
and Parent will use commercially reasonable efforts to cause the Proxy Statement

        SECTION 5.5 NO SOLICITATION. From the date hereof until the Effective
Time or, if earlier, the termination of this Agreement, the Company and its
Subsidiaries shall not (whether directly or indirectly through advisors, agents
or other intermediaries), and the Company shall cause their respective officers,
directors, advisors (including its financial advisors, attorneys and
accountants), representatives or other agents not to, directly or indirectly,
(a) solicit, initiate or encourage any Acquisition Proposal (as defined
hereafter) or (b) engage in discussions or negotiations with, or disclose any
non-public information relating to the Company or its Subsidiaries or afford
access to the properties, books or records of the Company or its Subsidiaries
to, any Person or group (other than Parent or any designees of Parent)
concerning any Acquisition Proposal PROVIDED, HOWEVER, that if the Board of
Directors of the Company determines in good faith, based on such matters as it
deems relevant, acting only after consultation with WSGR (or other legal counsel
of nationally recognized standing) that the failure to do so would be a breach
of its fiduciary duties to the Company's stockholders under the DGCL, the
Company may, in response to an Acquisition Proposal that was not solicited and
that the Board of Directors of the Company determines, based upon the advice of
CSFB (or another financial advisor of nationally recognized standing), is from a
Person or group other than the Parent or its affiliates that is capable of
consummating a Superior Proposal and only for so long as the Board of Directors
so determines that its actions are likely to lead to a Superior Proposal, (i)
furnish information to any such Person or group only pursuant to a
confidentiality agreement substantially in the same form as was executed by
Parent prior to the execution of this Agreement and only if copies of such
information are concurrently provided to Parent, and (ii) participate in
discussions and negotiations regarding such proposal or offer. The Company shall
promptly (and in any event within one business day after becoming aware thereof)
(i) notify Parent in the event the Company or any of its Subsidiaries or other
affiliates or any of their respective officers, directors, employees and agents
receives any Acquisition Proposal, including the material terms and conditions
thereof and the identity of the party submitting such proposal, and any request
for confidential information in connection with a potential Acquisition
Proposal, (ii) provide a copy of any written agreements, proposals or other
materials the Company receives from any such Person or group (or its
representatives), (iii) provide Parent with copies of all information furnished
to any such Person or group pursuant to clause (i) of the preceding sentence if
such information has not been previously furnished to Parent and (iv) notify
Parent of any material changes or developments with respect to any of the
matters described in clauses (i) or (ii). For purposes of this Agreement,
"ACQUISITION PROPOSAL" with respect to a Person means any offer or proposal for
a merger, consolidation, recapitalization, liquidation or other business
combination involving such Person or the acquisition or purchase of over 50% or
more of any class of equity securities of such Person, or any tender offer
(including self-tenders) or exchange offer that if consummated would result in
any Person beneficially owning 50% or more of any class of equity securities of
such Person, or a substantial portion of the assets of, such Person and its
Subsidiaries taken as a whole (it being understood by the parties that the
assets of the Company not constituting the Semiconductor Business are a
substantial portion of the assets of the Company and its Subsidiaries, taken as
a whole), other than the transactions contemplated by this Agreement (including
the Semi Disposition). As used herein, a "SUPERIOR PROPOSAL" shall

                                      -38-
<PAGE>   43

mean a bona fide Acquisition Proposal which in the reasonable good faith
judgment of the Company's Board of Directors, based on such matters as it deems
relevant, including in the case of clauses (i) and (ii) below the advice of the
Company's financial advisor, (i) provides greater benefits to the Company's
stockholders than those provided pursuant to this Agreement, (ii) provides that
any financing required to consummate the transaction contemplated by the offer
is either in the possession of the Person making such Acquisition Proposal or is
likely to be obtained by such Person on a timely basis, and (iii) does not
contain a "right of first refusal" or "right of first offer" with respect to any
counter-proposal that Parent might make; PROVIDED, FURTHER, that the Board of
Directors of the Company by a majority vote determines in its good faith
judgment that such Acquisition Proposal is reasonably capable of being completed
(taking into account all legal, financial, regulatory and other aspects of the
proposal and the person making the proposal). Nothing contained in this Section
5.5 shall prohibit the Company or the Company's Board of Directors from taking
and disclosing to the Company's stockholders a position with respect to a tender
or exchange offer by a third party pursuant to Rules 14d-9 and 14e-2(a)
promulgated under the Exchange Act or from making any disclosure required by
applicable law.

        SECTION 5.6 DIRECTOR AND OFFICER LIABILITY.

Certificate of Incorporation or by-laws of the Company or an agreement between
an Indemnitee and the Company or a Subsidiary of the Company as in effect as of
the date hereof shall survive the Merger and continue in full force and effect
in accordance with its terms.

            (b) Subject to the terms and conditions set forth on Schedule
1.5(a), for six years after the Effective Time, the Surviving Corporation shall
provide officers' and directors' liability insurance in respect of acts or
omissions occurring prior to the Effective Time covering each such Person
currently covered by the Company's officers' and directors' liability insurance
policy on terms with respect to coverage and amount no less favorable than those
of such policy in effect on the date hereof; PROVIDED, HOWEVER, that in no event
shall the Surviving Corporation be required to expend more than an amount per
year equal to 200% of current annual premiums paid by the Company for such
insurance (the "MAXIMUM AMOUNT") to maintain or procure insurance coverage
pursuant hereto; PROVIDED, FURTHER, that if the amount of the annual premiums
necessary to maintain or procure such insurance coverage exceeds the Maximum
Amount, the Surviving Corporation shall maintain or procure, for such six-year
period, the most advantageous policies of directors' and officers' insurance
obtainable for an annual premium equal to the Maximum Amount.

            (c) The obligations of Parent and the Surviving Corporation under
this Section 5.6 shall not be terminated or modified in such a manner as to
adversely affect any

                                      -39-
<PAGE>   44

Indemnitee to whom this Section 5.6 applies without the consent of such affected
Indemnitee (it being expressly agreed that the Indemnitees to whom this Section

determining whether any action by or in respect of, or filing with, any
Governmental Entity is required, or any actions, consents, approvals or waivers
are required to be obtained from parties to any material contracts, in
connection with the consummation of the transactions contemplated by this
Agreement and (iii) in seeking any such actions, consents, approvals or waivers
or making any such filings, furnishing information required in connection
therewith or with the Proxy Statement and the Form S-4 and seeking timely to
obtain any such actions, consents, approvals or waivers. Without limiting the
provisions of this Section 5.8, each party hereto shall file with the Department
of Justice and the Federal Trade Commission a Pre-Merger Notification and Report
Form pursuant to the HSR Act in respect of the transactions contemplated hereby
within ten (10) days of the date of this Agreement, and each party will use
commercially reasonable efforts to take or cause to be taken all actions
necessary, including to promptly and fully comply with any requests for
information from regulatory Governmental Entities, to obtain any clearance,
waiver, approval or authorization relating to the HSR Act that is necessary to
enable the parties to consummate the transactions contemplated by this
Agreement. Without limiting the provisions of this Section 5.8, each party
hereto shall use commercially reasonable efforts to promptly make the filings
required to be made by it with all foreign Governmental Entities in any
jurisdiction in which the parties believe it is necessary or advisable.

            (b) The Company and Parent shall each use commercially reasonable
efforts to resolve such objections, if any, as may be asserted with respect to
the Merger or any other transaction contemplated by this Agreement under any
Antitrust Law (as defined below). If any administrative, judicial or legislative
action or proceeding is instituted (or threatened to be instituted) challenging
the Merger or any other transaction contemplated by this Agreement as violative
of any Antitrust Law, the Company and Parent shall each cooperate 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 temporary,
preliminary or permanent) that is in effect and that restricts, prevents or
prohibits consummation of the Merger or any other transaction contemplated by
this Agreement, including, without limitation, by pursuing all reasonable
avenues of administrative and judicial appeal. Notwithstanding anything to the
contrary in this Agreement, none of Parent, any of

                                      -40-
<PAGE>   45

its Subsidiaries or the Surviving Corporation, shall be required (and the
Company shall not, without the prior written consent of Parent, agree, but
shall, if so directed by Parent, agree) to hold separate or divest any of their
respective assets or operations or enter into any consent decree or licensing or
other arrangement with respect to any of their assets or operations.

            (c) Each of the Company and Parent shall promptly inform the other
party of any material communication received by such party from the Federal
Trade Commission, the Antitrust Division of the Department of Justice, or any
other governmental or regulatory authority regarding any of the transactions
contemplated hereby.

            (d) "ANTITRUST LAW" means the Sherman Act, as amended, the Clayton
Act, as amended, and all other federal, state and foreign statutes, rules,
regulations, orders, decrees, administrative and judicial doctrines, and other
laws that are designed or intended to prohibit, restrict or regulate competition
or actions having the purpose or effect of monopolization or restraint of trade.

release or other public announcement with respect to the Merger, this Agreement

        SECTION 8.3 INTERPRETATION. References herein to the "knowledge" (and
all variants and derivatives thereof) of a party shall mean the actual knowledge
of the executive officers of such party. Whenever the words "include,"
"includes" or "including" are used in this Agreement they shall be deemed to be
followed by the words "without limitation." As used in this Agreement, the term
"affiliate" shall have the meaning set forth in Rule 12b-2 promulgated under the
Exchange Act.

        The article and section headings contained in this Agreement are solely
for the purpose of reference, are not part of the agreement of the parties
hereto and shall not in any way affect the meaning or interpretation of this
Agreement. Any matter disclosed pursuant to any Schedule of the Company
Disclosure Schedule or the Parent Disclosure Schedule shall not be deemed to be
an admission or representation as to the materiality of the item so disclosed.

        SECTION 8.4 AMENDMENTS, MODIFICATION AND WAIVER. (a) Except as may
otherwise be provided herein, any provision of this Agreement may be amended,
modified or waived by the parties hereto, by action taken by or authorized by
their respective Board of Directors, prior to the Closing Date if, and only if,
such amendment or waiver is in writing and signed, in the case of an amendment,

            (b) No failure or delay by any party in exercising any right, power

partial exercise thereof preclude any other or further exercise thereof or the
exercise of any other right, power or privilege. The rights and remedies herein
provided shall be cumulative and not exclusive of any rights or remedies
provided by law.

        SECTION 8.5 SUCCESSORS AND ASSIGNS. The provisions of this Agreement

may assign, delegate or otherwise transfer any of its rights or obligations
under this Agreement without the consent of the other party hereto.

        SECTION 8.6 SPECIFIC PERFORMANCE. The parties acknowledge and agree that
any breach of the terms of this Agreement would give rise to irreparable harm
for which money damages would not be an adequate remedy and accordingly the
parties agree that, in addition to any other remedies, each shall be entitled to
enforce the terms of this Agreement by a decree of specific performance without
the necessity of proving the inadequacy of money damages as a remedy.

        SECTION 8.7 GOVERNING LAW. This Agreement shall be governed by and
construed in accordance with the laws of the State of Delaware (regardless of
the laws that might otherwise

                                      -50-

effect, performance and remedies.

        SECTION 8.8 SEVERABILITY. If any term or other provision of this
Agreement is invalid, illegal or incapable of being enforced by any rule of law,
or public policy, all other conditions and provisions of this Agreement shall
nevertheless remain in full force and effect so long as the economic or legal
substance of the transactions contemplated herein are not affected in any manner
materially adverse to any party hereto. Upon such determination that any term or
other provision is invalid, illegal or incapable of being enforced, the parties
hereto shall negotiate in good faith to modify this Agreement so as to effect
the original intent of the parties as closely as possible in a mutually
acceptable manner.

        SECTION 8.9 THIRD PARTY BENEFICIARIES. This Agreement is solely for the
benefit of the Company and its successors and permitted assigns, with respect to
the obligations of Parent under this Agreement, and for the benefit of Parent
and its successors and permitted assigns, with respect to the obligations of the
Company under this Agreement, and this Agreement shall not, except to the extent
necessary to enforce the provisions of Article I and Section 5.6 hereof be
deemed to confer upon or give to any other third party any remedy, claim,
liability, reimbursement, cause of action or other right.

        SECTION 8.10 ENTIRE AGREEMENT. This Agreement, including any exhibits or
schedules hereto and the Confidentiality Agreement constitute the entire
agreement among the parties hereto with respect to the subject matter hereof and

have received counterparts hereof signed by all of the other parties hereto.
