                  (b) Effectiveness and Effects of the Merger. Subject to the
satisfaction or waiver of the conditions set forth in Article VIII in
accordance with this Agreement, the Merger shall become effective upon the
occurrence of the filing in the office of the Secretary of State of the State
of Delaware of a certificate of merger in accordance with Section 251 of the

powers and franchises of the Company and Transition shall be vested in the
Surviving Corporation, and all debt, liabilities and duties of the Company and
Transition shall become the debt, liabilities and duties of the Surviving
Corporation.

                  (c) Certificate of Incorporation and By-Laws. The certificate
of incorporation and by-laws of Transition, as in effect immediately prior to

incorporation amended to read: "The name of the Corporation is Arris
Corporation," and the by-laws shall be amended to reflect the name change, and

<PAGE>   13


earlier of their resignation or removal or otherwise ceasing to be a director
or until their respective successors are duly elected and qualified, as the
case may be.

         2.02.    Effective Date and Effective Time. Subject to the
satisfaction or waiver (subject to applicable law) of the conditions set forth

         3.01.    Conversion of Shares. Subject to the provisions of this
Agreement, at the Effective Time, automatically by virtue of the Merger and
without any action on the part of any party or stockholder:

                  (a)      Conversion of Transition Common Stock. Each share of
common stock, par value $.01 per share, of Transition (the "Transition Common
Stock") issued and outstanding immediately prior to the Effective Time that is
owned by Newco shall remain outstanding and thereafter be deemed to be a fully
paid, non-assessable and validly issued share of Surviving Corporation common
stock, par value $.01 per share.

                  (b)      Conversion of Company Common Stock. Each share of
common stock, par value $.01 per share, of the Company (the "Company Common
Stock") issued and outstanding immediately prior to the Effective Time (other
than shares of Company Common Stock to be canceled pursuant to Section 3.01(c))
shall become and be converted into the right to receive one share of Newco
common stock, par value $.01 per share ("Newco Common Stock"). All of the
shares of Company Common Stock converted into the right to receive Newco Common
Stock pursuant to this Article III, shall no longer be outstanding and shall
automatically be canceled and shall cease to exist as of the Effective Time.

                  (c)      Treasury Shares. Each share of Company Common Stock
held by the Company or any wholly-owned Subsidiary of the Company as Treasury
Shares immediately prior to the Effective Time shall no longer be outstanding
and shall automatically be canceled and retired at the Effective Time and no
consideration shall be issued in exchange therefor.

                  (d)      Conversion of Newco Common Stock. Each share of
common stock, par value $.01 per share, of Newco issued and outstanding
immediately prior to the Effective Time


                                      10
<PAGE>   14


that is owned by the Company shall no longer be outstanding and shall be
canceled and shall cease to exist as of the Effective Time.

         3.02.    Rights as Stockholders; Stock Transfers. At the Effective
Time, holders of Company Common Stock shall cease to be, and shall have no
rights as, stockholders of the Company, other than the right to receive any
dividend or other distribution with respect to such Company Common Stock with a
record date occurring prior to the Effective Time and the consideration
provided under this Article III. After the Effective Time, there shall be no
transfers on the stock transfer books of the Company or the Surviving
Corporation of shares of Company Common Stock.

         3.03.    Exchange Procedures.

                  (a)      At or prior to the Effective Time, Newco shall
deposit, or shall cause to be deposited, with a bank or trust company having
(or whose parent has) net capital of not less than $100,000,000 (the "Exchange
Agent"), for the benefit of the holders of certificates formerly representing
shares of Company Common Stock ("Old Certificates"), for exchange in accordance
with this Article III, certificates representing the shares of Newco Common
Stock ("New Certificates") (such New Certificates being hereinafter referred to
as the "Exchange Fund") to be delivered pursuant to this Article III in
exchange for outstanding shares of Company Common Stock.

                  (b)      As promptly as practicable after the Effective Date,
Newco shall send or cause the Exchange Agent to send or cause to be sent to
each former holder of record of shares (other than Treasury Shares) of Company
Common Stock immediately prior to the Effective Time transmittal materials for
use in exchanging such stockholder's Old Certificates for the consideration set
forth in this Article III. Newco shall cause the New Certificates representing
shares of Newco Common Stock into which a stockholder's shares of Company
Common Stock are converted at the Effective Time and any dividends or
distributions which such person shall be entitled to receive pursuant to this
Article III, to be delivered to such stockholder upon delivery to the Exchange
Agent of Old Certificates representing such shares of Company Common Stock (or,
pursuant to Section 3.03(f), a surety bond reasonably satisfactory to Newco and
the Exchange Agent, if any of such certificates are lost, stolen or destroyed)
owned by such stockholder. No interest will be paid in respect of dividends or
distributions which any such person shall be entitled to receive pursuant to
this Article III upon such delivery.

                  (c)      Notwithstanding the foregoing, neither the Exchange
Agent nor any party hereto shall be liable to any former holder of Company
Common Stock for any amount delivered to a public official pursuant to
applicable abandoned property, escheat or similar laws.

                  (d)      No dividends or other distributions with respect to
shares of Newco Common Stock with a record date occurring after the Effective
Time shall be paid to the holder of any unsurrendered Old Certificate
representing shares of Company Common Stock converted in the Merger into the
right to receive shares of Newco Common Stock until the holder thereof


                                      11
<PAGE>   15


shall be entitled to receive New Certificates in exchange therefor in
accordance with this Article III. After becoming so entitled in accordance with
this Article III, the record holder thereof also shall be entitled to receive
any such dividends or other distributions, without any interest thereon, which
theretofore had become payable with respect to shares of Newco Common Stock
such holder had the right to receive upon surrender of the Old Certificate, and
payment thereof shall be made promptly following the later of (i) the date on
which such holder shall become entitled to receive New Certificates and (ii)
the payment date with respect to such dividend or other distribution.

                  (e)      Any portion of the Exchange Fund that remains
unclaimed by the stockholders of the Company for three months after the
Effective Time shall, upon demand by Newco, be paid or delivered to Newco. Any
stockholders of the Company who have not theretofore complied with this Article
III shall thereafter look only to Newco for delivery of the shares of Newco
Common Stock, and payment of unpaid dividends and distributions on the shares
of Newco Common Stock deliverable in respect of each share of Company Common
Stock such stockholder holds, as determined pursuant to this Agreement, in each
case, without any interest thereon.

                  (f)      If any Old Certificate shall have been lost, stolen
or destroyed, upon the making of an affidavit of that fact by the person
claiming such Old Certificate to be lost, stolen or destroyed and the posting
by such person of a bond in such reasonable amount as Newco may direct as
indemnity against any claim that may be made against it or the Surviving
Corporation with respect to such Old Certificate, Newco shall, in exchange for
such lost, stolen or destroyed Old Certificate, deliver or cause the Exchange
Agent to deliver a New Certificate in respect thereof pursuant to this Article
III.

         3.04.    Stock Options and Other Stock Plans; Restricted Stock.

                  (a)      Effective at the Effective Time, each option to
purchase shares of Company Common Stock or stock units convertible into shares
of Company Common Stock (collectively, the "Company Stock Options") granted to
employees or directors of, or consultants or advisors to, the Company or any
Subsidiary thereof pursuant to the terms of the Company Stock Option Plans that
is outstanding immediately prior to the Effective Time shall be assumed by
Newco and deemed to constitute an option to acquire or a stock unit convertible
into, on substantially the same terms and conditions (including such terms
relating to the exercise price, vesting and exercisability of the Company Stock
Options and terms relating to adjustments for any stock dividend, subdivision,
reclassification, recapitalization, split, combination, exchange of shares or
similar transaction following such assumption) as were applicable under such
Company Stock Option immediately prior to the Effective Time, the same number
of shares of Newco Common Stock. The date of grant of each such Company Stock
Option shall be the date on which such Company Stock Option was originally
granted. As soon as reasonably practicable following the Effective Date, Newco
shall cause to be delivered to each holder of a Company Stock Option that has
been assumed by Newco pursuant to this Section 3.04 a notice stating that (x)
such Company Stock Option has been converted into an option to purchase shares
of Newco


                                      12
<PAGE>   16


Common Stock, (y) such Company Stock Option has been assumed by Newco and shall
continue in effect subject to all of the terms and conditions applicable
thereto immediately prior to the Effective Time and (z) setting forth the
number of shares of Newco Common Stock covered by such Company Stock Option and
the per share option exercise price for such shares of Newco Common Stock. From
and after the Effective Time, Newco shall comply with the terms of each Company
Stock Option Plan pursuant to which the Company Stock Options were granted;
provided, that (i) the board of directors of Newco or an authorized committee
thereof shall succeed to the authorities and responsibilities of the Company
Board or any committee thereof under the Company Stock Option Plans; (ii) the
terms of the Company Stock Option Plans shall be amended as necessary to
reflect the assumption of the Company Stock Options contemplated hereunder; and
(iii) so long as it is not inconsistent with the foregoing, Newco, at its
election, may replace the Company Stock Options with options granted under a
new Newco plan.

                  (b)      Prior to the Effective Date, the Company shall take
all necessary or appropriate action (including amending any of the Company
Stock Option Plans or making adjustments as permitted thereby) to effectuate
the assumption and conversion of the Company Stock Options by Newco and the
assignment to Newco of the authorities and responsibilities of the Company
Board or any committee thereof under the Company Stock Option Plans.

                  (c)      Newco shall cause to be taken all corporate action
necessary to reserve for issuance a sufficient number of shares of Newco Common
Stock for delivery upon exercise of Company Stock Options in accordance with
this Section 3.04. As soon as reasonably practicable following the Effective
Date, Newco shall use its reasonable efforts to cause the shares of Newco
Common Stock subject to Company Stock Options to be registered under the
Securities Act pursuant to a registration statement on Form S-8 (or any
successor or other appropriate forms) and shall use its reasonable efforts to
cause the effectiveness of such registration statement (and current status of
the prospectus or prospectuses contained therein) to be maintained for so long
as Company Stock Options remain outstanding.

                  (d)      Restricted Stock. If any shares of Company Common
Stock that are outstanding immediately prior to the Effective Time are unvested
or are subject to a repurchase option, risk of forfeiture or other condition
providing that such shares ("Company Restricted Stock") may be forfeited to or
repurchased by the Company upon termination or modification of the employment,
directorship or other relationship between the Company (and/or any Affiliate of
the Company) and the holder of such Company Restricted Stock under the terms of
any restricted stock agreement or other agreement with the Company (and/or the
relevant Affiliate of the Company) that does not by its terms provide that such
repurchase option, risk of forfeiture or other condition lapses upon
consummation of the Transactions, then the shares of Newco Common Stock issued
upon the conversion of such shares of Company Common Stock in the Merger will
continue to be unvested to the same extent and/or subject to the same
repurchase options, risks of forfeiture or other conditions (as applicable)
following the Effective Time, and the certificates representing such shares of
Newco Common Stock shall accordingly be marked with appropriate legends noting
such repurchase options, risks of forfeiture or other conditions.

shall provide or otherwise make available to the Existing Venture, in
immediately available U.S. funds, by wire transfer, the amount of outstanding
principal and accrued but unpaid interest under the Existing Venture Loan
Agreement, together with the amount of any other fees, charges and payments
payable by the Existing Venture under the Existing Venture Loan Agreement as of
the Closing Date, less the amount of any interest attributable to the first
$120,700,000 of such amount for the period from August 31, 2000 and until
December 31, 2000, but in no event to exceed $130,100,000 ( in the aggregate,
the "Outstanding Loan Amount");

                  (b)      at the Closing, the Existing Venture shall pay to
Nortel Networks LLC, in immediately available U.S. funds, by wire transfer, the
Outstanding Loan Amount;

                  (c)      at the Closing, Nortel Networks LLC shall pay to the
Company, in immediately available U.S. funds, by wire transfer, the portion of
the payment received by Nortel Networks LLC pursuant to Section 4.01(b) above
that is attributable to the Company's Optional Participating Interest and
Mandatory Participating Interest (as such terms are defined in the Existing
Venture Loan Agreement) actually purchased by the Company under the Existing
Venture Loan Agreement (the amount so payable by Nortel Networks LLC to the
Company, the "Participation Loan Amount"); and

                  (d)      upon payment of the amounts set forth in Sections
4.01(b) and (c) above, the Existing Venture Loan Agreement shall terminate (as
set forth in greater detail in, and subject to, the Termination Agreement), and
no further amounts may be advanced thereunder.

         4.02.    Satisfaction of Existing Obligations.

                  (a)      Between the date hereof and the Closing, the Company
and Nortel Networks shall keep their accounts payable to the Existing Venture
at least as current as they are on the date hereof.

                  (b)      Immediately prior to the Closing, each of the Company
and Nortel Networks shall make such payments as are necessary to comply with
the payment terms of its


                                      14
<PAGE>   18


obligations to the Existing Venture and, to the extent Nortel Networks elects
to do so to facilitate the payments described in paragraph (c) below, Nortel
Networks may prepay amounts that are not then due.

                  (c)      To the extent that it has funds to do so immediately
prior to the Closing, (i) first, the Existing Venture will pay all outstanding
amounts to its creditors other than Nortel Networks and its Affiliates
(regardless of whether then due), and (ii) second, the Existing Venture shall
pay Nortel Networks and its Affiliates, in both cases paying the amounts that
have been outstanding the longest first.

                  (d)      The phrase in paragraph (c) "funds to do so" shall
include cash on hand, funds generated from operations subsequent to the date
hereof including those that may previously have been used to reduce the amount
outstanding under the Existing Venture Loan Agreement (but not additional
borrowings under the Existing Venture Loan Agreement), and funds available
under the Company's new credit facility under the commitment letters attached
as Exhibit A to the extent that using such funds for such purpose will not
either (i) violate the terms of the Company's new credit facility, or (ii)
cause the Company's EBITDA leverage ratio to exceed 3.25 (as determined
pursuant to the Company's contemplated bank credit facility).

                  (e)      Following the Closing, the remaining amounts due from
the Existing Venture to Nortel Networks and its Affiliates shall be paid
consistent with their terms.

         4.03.    Redemption

in the Existing Venture, such portion to equal the fraction of Nortel Networks

                         REPRESENTATIONS AND WARRANTIES

         6.01.    Representations and Warranties of the Company, Newco and
Transition. Except as set forth in the Company Disclosure Schedule (each section
of which qualifies the correspondingly numbered representation and warranty or
covenant to the extent specified therein), the Company hereby represents and
warrants to Nortel Networks as follows:

                  (a)      Organization, Standing and Authority. Each of the
Company, Newco and Transition is a corporation duly organized, validly existing
and in good standing under the laws of the jurisdiction of its organization, and
is duly qualified to do business and is in good standing in the states of the
United States and foreign jurisdictions where its ownership or leasing of
property or assets or the conduct of its business requires it to be so
qualified, except where the failure to be so qualified and in good standing does
not have and would not reasonably be expected to have, individually or in the
aggregate, a Material Adverse Effect on the Company, Newco or Transition. Each
of the Company, Newco and Transition has in effect all federal, state, local and
foreign governmental authorizations necessary for it to own or lease its
properties and assets and to carry on its business as it is now conducted,
except where the failure to have in effect such authorizations does not have,
and would not reasonably be expected to have, individually or in the aggregate,
a Material Adverse Effect on the Company, Newco or Transition. Each of the
Company, Newco and Transition has made available to Nortel Networks a complete
and correct copy of its certificate of incorporation and by-laws, each as
amended and in full force and effect as of the date of this Agreement, and each
of the Company, Newco and Transition is not in violation of any provision
thereof.

                  (b)      Shares.

                           (i)      The authorized capital stock of the Company
consists of (A) 150,000,000 shares of Company Common Stock of which 38,093,366
shares were issued and outstanding as of September 30, 2000 (the "Capitalization
Date"), and (B) 5,000,000 shares of preferred stock, par value $1.00 per share
("Company Preferred Stock"), of which no shares were issued or outstanding as of
the Capitalization Date. Since the Capitalization Date, there have been no
issuances of shares of the capital stock of the Company other than issuances
permitted by Section 5.01(b).

                           (ii)     All issued and outstanding shares of Company
Common Stock have been duly authorized and validly issued, in compliance with
all applicable federal, state and foreign securities laws, and are fully paid
and nonassessable, and no class of capital stock of the Company is entitled to
preemptive rights.

                           (iii)    There were outstanding at the Capitalization
Date no Rights to acquire capital stock from the Company other than (A) Rights
to acquire up to 4,791,667 shares of Company Common Stock upon conversion of
notes issued under the Indenture, and (B)


                                       20
<PAGE>   24

Company Stock Options. Section 6.01(b)(iii) of the Company Disclosure Schedule
sets forth for all Company Stock Options (and all shares of Company Common Stock
issued pursuant to restricted stock awards made under any Company Plan)
outstanding at the Capitalization Date a true and complete list of the
following: their holders, their date of grant (or award), the number of shares
of Company Common Stock for which they are exercisable (or, with respect to
restricted stock awards, the number of shares awarded), and their exercise price
as currently in effect. No Rights to acquire capital stock from the Company have
been issued or granted, and no restricted stock awards have been made, since the
Capitalization Date other than issuances not prohibited by Section 5.01(b).

                           (iv)     The Newco Shares when issued as contemplated
by Articles III and IV hereof will be duly authorized, validly issued, in
compliance with all applicable federal, state and foreign securities laws, and
fully paid and non-assessable.

                  (c)      Subsidiaries.

                           (i)      Section 6.01(c)(i) of the Company Disclosure
Schedule sets forth a list as of the date hereof of all of the Company's
Significant Subsidiaries, together with their jurisdiction of organization.
Unless otherwise described therein, the Company owns, directly or indirectly,
beneficially and of record 100% of the issued and outstanding voting securities
of each such Subsidiary (other than directors' qualifying shares, if any). No
equity securities of any of the Company's Subsidiaries are or may become
required to be issued (other than to the Company or its wholly owned
Subsidiaries) by reason of any Rights, and there are no contracts, commitments,
understandings or arrangements by which any of such Subsidiaries is bound to
sell or otherwise transfer any shares of capital stock of any such Subsidiaries
(other than to the Company or its wholly owned Subsidiaries). In addition,
Section 6.01(c)(i) of the Company Disclosure Schedule lists as of the date of
this Agreement each corporation, partnership, limited liability company or
similar entity with respect to which, as of the date of this Agreement, the
Company or any Subsidiary of the Company owns more than 5% but less than a
majority of the voting equity or similar voting interest or any interest
convertible into, or exchangeable or exercisable for, more than 5% but less than
a majority of the voting equity or similar voting interest and which interest is
carried on the Company's most recent financial statements (or if not held as of
the date thereof, would be carried on the Company's financial statements if
prepared as of the date hereof) at a value in excess of $1,000,000
(collectively, the "Company Equity Interests"). All of the shares of capital
stock of each of the Subsidiaries of the Company and all the Company Equity
Interests held by the Company (including, without limitation, the Company's
limited liability company interest in the Existing Venture) and each Subsidiary
of the Company are fully paid and non-assessable and are owned by the Company or
such Subsidiary free and clear of any Liens. Other than with respect to the
Existing Venture, there are no material outstanding contractual obligations of
the Company or any of its Subsidiaries to provide funds to, or make any
investment (in the form of a loan, capital contribution or otherwise) in any
entity in which the Company or any Subsidiary of the Company owns a Company
Equity Interest.

<PAGE>   25

                           (ii)     Each of the Company's Significant
Subsidiaries has been duly organized and is validly existing in good standing
under the laws of the jurisdiction of its organization. Each of such
Subsidiaries is duly qualified to do business and in good standing in the
jurisdictions where its ownership or leasing of property or the conduct of its
business requires it to be so qualified and each has in effect all federal,
state, local and foreign governmental authorizations necessary for it to own or
lease its properties and assets and to carry on its business as it is now
conducted, except where the failure to be so duly qualified and in good standing
or to have in effect all federal, state, local, and foreign governmental
authorizations does not have, and would not reasonably be expected to have,
individually or in the aggregate, a Material Adverse Effect on the Company.

                           (iii)    All Subsidiaries of the Company, other than
the Significant Subsidiaries of the Company, if taken together and combined in a
single Subsidiary of the Company, would not constitute a Significant Subsidiary
of the Company.

                  (d)      Corporate Power. Each of the Company, Newco, and
Transition has the corporate power and authority to carry on its business as it
is now being conducted and to own all its properties and assets; and each such
party has the corporate power and authority to execute, deliver and perform its
obligations under this Agreement and each Ancillary Agreement to which it is a
party and to consummate the Transactions.

                  (e)      Corporate Authority.

                           (i)      Subject, in the case of the consummation of
the Merger, to receipt of the requisite approval and adoption of the "agreement
of merger" (as such term is used in Section 251 of the DGCL) contained in this
Agreement and the Merger by the holders of a majority of the outstanding shares
of Company Common Stock entitled to vote thereon, the Company Board having
unanimously adopted a resolution approving such "agreement of merger" and
declaring its advisability, with Mr. John Ian Craig abstaining, this Agreement,
the Ancillary Agreements and the Transactions have been duly authorized by all
necessary corporate action of the Company, Newco and Transition and their
respective Boards of Directors (assuming that neither Nortel Networks nor Nortel
Networks LLC is an "interested stockholder" of the Company, Newco or Transition
under Section 203 of the DGCL immediately before the execution and delivery of
this Agreement), prior to the date hereof (which action has not been rescinded
or modified in any way). The execution and delivery of this Agreement and the
Ancillary Agreements by the Company, Newco and Transition and the consummation
by the Company, Newco and Transition of the Transactions have been duly
authorized by the respective Boards of Directors of the Company, Newco and
Transition and by the Company as the sole shareholder of Newco and by Newco as
the sole shareholder of Transition. No other corporate proceedings on the part
of Newco or Transition are necessary to authorize this Agreement and the
Transactions.

                           (ii)     Each of this Agreement and the Ancillary
Agreements is, or in the event that such Ancillary Agreement is to be entered
into at Closing, will be, a legal, valid and


                                       22
<PAGE>   26

binding agreement of the Company, Newco and Transition (to the extent that it is
a party thereto), enforceable in accordance with its terms (except as such
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium, fraudulent transfer and similar laws of general
applicability relating to or affecting creditors' rights or by general equity
principles, whether considered at law or in equity).

                  (f)      No Defaults. Subject to receipt of the regulatory
approvals, and expiration of the waiting periods, referred to in Section 6.01(r)
and required filings under federal and state securities or other laws, the
execution, delivery and performance of this Agreement and the Ancillary
Agreements and the consummation of the Transactions by the Company, Newco and
Transition (to the extent that they are a party thereto), do not and will not
(i) constitute a breach or violation of, or a default under, any law, rule or
regulation or any judgment, decree, order, governmental permit or license, or
agreement, indenture or instrument of the Company or Newco or Transition or to
which the Company or Newco or Transition or any of their respective properties
or assets are subject or bound, (ii) constitute a breach or violation of, or a
default under, the articles or certificate of incorporation or by-laws of the
Company or Newco or Transition or (iii) require any consent or approval under
any such law, rule, regulation, judgment, decree, order, governmental permit or
license, agreement, indenture or instrument, except in the case of (i) and
(iii), where such breach, violation or default or the failure to obtain such
consents or approvals would not in the aggregate have a Material Adverse Effect
on the Company, Newco or Transition and would not prevent or impair the Company,
Newco or Transition's ability to consummate the Transactions. Section 6.01(f) of
the Company Disclosure Schedule contains a list of all consents of third parties
required under any material agreement to be obtained by the Company, Newco or
Transition prior to, or as a result of, the consummation of the Transactions.

                  (g)      Financial Reports and SEC Documents.

                           (i)      Except as set forth in Section 6.01(g) of
the Company Disclosure Schedule, with respect to the periods since December 31,
1997, the Company and its Subsidiaries have filed all reports and statements,
together with any amendments required to be made thereto, that were required to
be filed with the SEC.

                           (ii)     The Company's Annual Reports on Form 10-K

the Exchange Act, in the form filed, or to be filed (collectively, the "Company
SEC Documents"), with the SEC, as of the date filed (or, with respect to a

a subsequent filing prior to the date of this Agreement, then on the date of
such filing as so amended or superseded) (A) complied or will comply in all
material respects as to form with the applicable requirements under the
Securities Act or the Exchange Act, as the case may be; and (B) did not and will
not contain any untrue statement of a material fact or omit to state a material

Transition.

and performance by the Company, Newco and Transition of this Agreement and the

                           (iii)    None of the property currently owned, leased
or operated by the Company or by its Subsidiaries is subject to, or as a result
of the Transactions would be subject to, (i) the New Jersey Industrial Site
Recovery Act or any other state or local Environmental Laws which would impose
restrictions on the Transactions, such as notice, disclosure or advance approval
requirements, or (ii) any material Liens under any Environmental Laws.

necessary to conduct the business of (or manufacture or sell the products of)
the Company and its Subsidiaries as currently conducted or currently anticipated

                           (ii)     The Company and its Subsidiaries have good
and valid title to all material Company Intellectual Property Rights owned by

its Subsidiaries do not already own by operation of law. The Company and its
Subsidiaries have taken reasonable and appropriate steps to protect and preserve
the confidentiality of all of their Trade Secrets and to protect the proprietary
nature of each other item of Company Intellectual Property Rights. Except as set
forth in Section 6.01(p)(iii) of the Company Disclosure Schedule, there are no,

infringements of any material Company Intellectual Property Rights, and

Knowledge, all uses by other Persons of Company Intellectual Property Rights

Section 6.01(p)(iii) of the Company Disclosure Schedule, neither the Company
Intellectual Property Rights nor the use or other exploitation thereof by the
Company or its Subsidiaries (or any consultant, contractor or employee of the
Company and its Subsidiaries who contributes to or has contributed to or
participated in the creation or development of material Company Intellectual
Property Rights) in the conduct of their business as is currently conducted or
proposed to be conducted, nor any product or service of the Company or its

party Intellectual Property Rights.

                           (iv)     Except as set forth in Section 6.01(p)(iv)

material Company Intellectual Property Rights or (B) is the subject of any claim
of infringement or misappropriation by the Company or any of its Subsidiaries of
any third party Intellectual Property Rights.

Returns") with respect to it or any of its Subsidiaries, have been or will be
timely filed, or requests for extensions have been timely filed and have not

filed by the Company are complete and accurate in all material respects; (C) all
Taxes due and payable (without regard to whether such Taxes have been assessed)
have been paid or adequate reserves have been established for the payment of

failures did not exceed $5,000,000 in the aggregate; (D) the proper and accurate
amounts have been withheld from all employees (and timely paid to the
appropriate Governmental Authority or set aside in an account for such purposes)
for all periods through the Effective Date in compliance in all material
respects with all Tax withholding provisions of applicable federal, state, local
and foreign laws (including, without limitation, income, social security, and
employment tax withholding for all types of compensation); (E) neither the

                           (ii)     The Company, Newco and Transition have no
reason to believe that any conditions exist that might prevent or impede the
Merger from qualifying as a reorganization within the meaning of Section 368(a)
of the Code and as an exchange under Section 351 of the Code or the

or successor, by contract, or otherwise.

of the Company Disclosure Schedule, neither the Company nor any Subsidiary is or
has ever been a member of a group of corporations with which it has filed (or

a group of which only the Company and the Subsidiaries are or were members.

                           (v)      Neither the Company nor any Subsidiary has
undergone a change in its method of accounting resulting in a material
adjustment to its taxable income pursuant to Section 481(a) of the Code.

<PAGE>   34

                           (vi)     Except with regard to the Merger and other
transactions contemplated by this Agreement, neither Newco nor the Company
currently has any plan or intention to liquidate, merge with another entity
(including each other) or otherwise cease to exist, to transfer any of the
assets thereof other than in the ordinary course of business, to transfer any
interest in the Existing Venture or cause the Existing Venture to liquidate,
merge with another entity or otherwise cease to exist, or to transfer any of the
assets thereof other than in the ordinary course of business. As of the date of
consummation of the transactions contemplated by this Agreement, Newco and the
Company have no plan or intention to engage in a transaction that (i) would be
an Integrated Transaction (as defined in Section 7.14 hereof) and (ii) would
cause Nortel Networks LLC and the stockholders of the Company immediately before
the transactions contemplated by this Agreement and any Integrated Transferors
(as defined in Section 7.14 hereof) not to be in control (within the meaning of

contemplated by this Agreement.

                  (r)      Regulatory Approvals. No consents or approvals of, or
filings or registrations with, any Governmental Authority or instrumentality are
necessary to consummate the Merger except (i) as may be required under, and

antitrust or other competition laws of other jurisdictions; (ii) the filing with
the SEC of the Company Proxy Statement and the filing and declaration of

to be obtained under the securities or "Blue Sky" laws of various states in
connection with the issuance of shares of Newco Common Shares Stock in the
Transactions; and (v) as may be required under Section 721 of the U.S. Defense
Production Act of 1950, as amended, and the rules promulgated thereunder
("Exon-Florio") and the rules and regulations promulgated by the U.S. Department
of Defense.

                  (s)      Fairness Opinion. The Company Financial Advisor has

hereof, no event has occurred or circumstance arisen that, individually or taken
together with all other facts, circumstances and events (described in any
paragraph of Section 6.01 or otherwise), has had or is reasonably likely to have
a Material Adverse Effect with respect to the Company, Newco or Transition.

                  (u)      Financing Commitment Letters. The financing
commitment letters previously delivered by the Company to Nortel Networks are
true and correct, have not been


                                       31

attached as Exhibit A.

the Transactions have been duly authorized and approved by all necessary
corporate action of Nortel Networks and Nortel Networks LLC and their respective
Board of Directors and Managing Member prior to the date hereof (which action
has not been rescinded or modified in any way). The execution and delivery of

the Transactions have been duly authorized by all requisite corporate or limited
liability company (as applicable) action on the parts of Nortel Networks and

are necessary to authorize this Agreement and the Transactions.

                           (ii)     Each of this Agreement and the Ancillary
Agreements is, or in the event that such Ancillary Agreement is to be entered
into at Closing, will be a legal, valid and binding agreement of each of Nortel
Networks and Nortel Networks LLC (to the extent that it is a party thereto),
enforceable in accordance with its terms (except as such enforceability may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium,
fraudulent transfer and similar laws of general applicability relating to or
affecting creditors' rights or by general equity principles, whether considered
at law or in equity).

                  (d)      No Defaults. Subject to receipt of the regulatory
approvals, and expiration of the waiting periods, referred to in Section

default under, any law, rule or regulation or any judgment, decree, order,
governmental permit or license, or agreement, indenture or instrument of Nortel
Networks or Nortel Networks LLC or to which Nortel Networks or Nortel Networks
LLC or any of their respective properties or assets are subject or bound, (ii)

decree, order, governmental permit or license, agreement, indenture or
instrument, except in the case of (i) and (iii), where such breach, violation or
default or the failure to obtain such consents or approvals would not in the
aggregate have a Material Adverse Effect on Nortel Networks or Nortel Networks
LLC and would not prevent or materially impair Nortel Networks or Nortel
Networks LLC's ability to consummate the Transactions. Section 6.02(d) of the
Nortel Networks Disclosure Schedule contains a list of all consents of third

Asset Sale and Contribution Agreement between Nortel Networks LLC and the
Existing Venture dated as of March 31, 1999. The Registration Statement and the

the effect on, the Transactions contemplated by this Agreement from, or if
necessary challenge the validity or applicability of, any applicable Takeover
Laws, as now or hereafter in effect, including, without limitation, Section 203

Authorities necessary to consummate the Transactions contemplated by this
Agreement and (ii) to cause the Merger and the Contribution to be consummated as
expeditiously as reasonably practicable, including, without limitation, seeking
an early termination of the HSR Act waiting period; provided, however, that,

Networks or any of its Subsidiaries to disclose, in response to any "second
request" under the HSR Act, any information which Nortel Networks deems, in good
faith due to the confidential and material nature of such information, to be
inappropriate for such disclosure shall not constitute, or be deemed to
constitute, a breach of this Section 7.09(a) if the relevant Governmental
Authority does not agree, prior to any such disclosure, to accord confidential
treatment to such information. Each of Nortel Networks and the Company shall
have the right to review in advance, and to the extent practicable each will
consult with the other, in each case subject to applicable laws relating to the
exchange of information, with respect to, all material written information
submitted to any third party or any Governmental Authority in connection with
the Transactions contemplated by this Agreement. In exercising the foregoing
right, each of the parties hereto agrees to act reasonably and as promptly as
practicable. Each party hereto agrees that it will consult with the other party
hereto with respect to the obtaining of all material permits, consents,
approvals and authorizations of all third parties and Governmental Authorities
necessary or advisable to consummate the Transactions contemplated by this
Agreement and each party will keep the other party apprised of the status of
material matters relating to completion of the Transactions contemplated hereby.

                  (b) Each party agrees, upon request, to furnish the other
party with all information concerning itself, its Subsidiaries, directors,
officers and stockholders and such other matters as may be reasonably necessary
or advisable in connection with any filing, notice or application made by or on
behalf of such other party or any of its Subsidiaries to any third party or
Governmental Authority; provided, however that nothing in this Section 7.09(b)
shall require


                                       41

<PAGE>   45

the release by Nortel Networks or Nortel Networks LLC of internal or otherwise
confidential information.

                  (c) In furtherance and not in limitation of the covenants of
the parties contained in Sections 7.09(a) and (b), if any objections are
asserted with respect to the Transactions contemplated by this Agreement under
any Regulatory Law or if any suit is instituted or threatened by any
Governmental Authority or any private party challenging any of the Transactions
contemplated by this Agreement as violative of any Regulatory Law, each of
Nortel Networks and the Company shall use its reasonable efforts to resolve any
such objections or challenge as such Governmental Authority or private party may
have to such Transactions under such Regulatory Law so as to permit consummation
of the Transactions contemplated by this Agreement, and if any administrative or
judicial action or proceeding, including any proceeding by a private party, is
instituted (or threatened to be instituted) challenging any transaction
contemplated by this Agreement as violative of any Regulatory Law, each of
Nortel Networks and the Company shall cooperate in all respects with each other
and use its respective reasonable efforts to contest and resist any such action
or proceeding and to have vacated, lifted, reversed or overturned any decree,
judgment, injunction or other order, whether temporary, preliminary or
permanent, that is in effect and prohibits, prevents or restricts consummation
of the Transactions contemplated by this Agreement. Notwithstanding the
foregoing or any other provision of this Agreement, nothing in this Section 7.09
shall limit a party's rights under Sections 8.01(b) and 9.01(d) so long as such
party has theretofore complied in all respects with its obligations under this
Section 7.09.

                  (d) Nothing contained in this Section 7.09 shall require the
Company or Newco or any of their respective Subsidiaries to sell or otherwise
dispose of, or to hold separately, or permit the sale or other disposition of,
any assets of Newco, the Company or their respective Subsidiaries, or require
Newco to refrain from exercising full authority over the Company and its
Subsidiaries after the Effective Time, whether as a condition to obtaining any
approval from a Governmental Authority or any other Person or for any other
reason.

         7.10.    Indemnification.

                  (a) Following the Effective Date and until the expiration of
any applicable statutory limitations period, Newco shall indemnify, defend and
hold harmless the present and former directors and officers of the Company and
its Subsidiaries (including the Existing Venture) (each, an "Indemnified Party")
against all costs or expenses (including reasonable attorneys' fees), judgments,
fines, losses, claims, damages or liabilities (collectively, "Costs") incurred
in connection with any claim, action, suit, proceeding or investigation, whether
civil, criminal, administrative or investigative, arising out of actions or
omissions occurring at or prior to the Effective Time (including, without
limitation, the Transactions contemplated by this Agreement) to the fullest
extent that the Company is permitted to indemnify its directors and officers
under the laws of the State of Delaware, the Company Certificate and the
Company's by-laws as in effect on the date hereof (and Newco shall also advance
expenses as incurred to the fullest extent permitted under applicable law).

<PAGE>   46

                  (b) Any Indemnified Party wishing to claim indemnification
under Section 7.10(a), upon learning of any claim, action, suit, proceeding or
investigation described above, shall promptly notify Newco thereof; provided,
that the failure so to notify shall not affect the obligations of Newco under
Section 7.10(a) unless and to the extent such failure materially increases
Newco's liability under such subsection (a).

                  (c) If Newco or any of its successors or assigns shall
consolidate with or merge into any other entity and shall not be the continuing
or surviving entity of such consolidation or merger or shall transfer all or
substantially all of its assets to any entity, then and in each case, proper
provision shall be made so that the successors and assigns of Newco shall assume
the obligations set forth in this Section 7.10.

         7.11.    Certain Employee Benefit Matters.

                  To the extent applicable, Newco and the Company shall each
take such reasonable steps as are required to cause the disposition and
acquisition of equity securities (including derivative securities) pursuant to
Article III of this Agreement in connection with the consummation of the Merger
by each individual who is an officer or director of the Company to qualify for
exemption from Section 16(b) of the Exchange Act pursuant to Rule 16b-3(e)
promulgated under the Exchange Act.

         7.12.    Accountants' Letters. The Company shall use its reasonable
best efforts to cause to be delivered to Nortel Networks a letter of Ernst &
Young L.L.P., independent auditors ("E&Y"), and Nortel Networks shall use its
reasonable best efforts to cause to be delivered to the Company a letter of
Deloitte & Touche LLP, independent auditors ("Deloitte"), each dated a date
within two Business Days of the date on which the Registration Statement shall
become effective and addressed to such other party, and in form and substance
customary for "comfort" letters delivered by independent accountants in
accordance with Statement of Accounting Standards No. 72.

         7.13.    Notification of Certain Matters.

                  (a) Each of the Company and Nortel Networks shall give prompt
notice to the other of any fact, event or circumstance known to it that would
cause or constitute a material breach of any of its representations, warranties,
covenants or agreements contained herein.

                  (b) Nortel Networks shall promptly notify the Company, and the
Company shall promptly notify Nortel Networks, in writing, of any notice or
other communication from any regulatory authority or self-regulatory
organization in connection with the Transactions contemplated by this Agreement.

                  (c) Each of Nortel Networks and the Company shall promptly
notify the other of any fact, event or circumstance known to it that could
reasonably be expected to, individually or taken together with all other facts,
events and circumstances known to it, cause the Merger to


                                       43

<PAGE>   47

fail to qualify as a "reorganization" within the meaning of Section 368(a) of
the Code or the Contribution to constitute an exchange under Section 351 of the
Code.

         7.14.    Certain Tax Matters.

                  (a) Each of Nortel Networks, Nortel Networks LLC, Newco and
the Company will use its reasonable best efforts to cause (i) the Merger to
constitute a reorganization within the meaning of Section 368(a) of the Code and
to constitute an exchange under Section 351 of the Code (including without
limitation by refraining from taking any action inconsistent with such treatment
of the Contribution and the Merger after the Closing), (ii) the Contribution to
constitute an exchange under Section 351 of the Code (including without
limitation by refraining from taking any action inconsistent with such treatment
of the Contribution and the Merger after the Closing), and (iii) to timely
satisfy, or cause to be timely satisfied, all applicable tax reporting and
filing requirements contained in the Code and with respect to the Merger and the
Contribution. For the avoidance of doubt, the provisions of this Section 7.14
shall survive Closing.

                  (b) Prior to or after the Effective Time, the Company will not
engage in a transaction that, by itself or in combination with other
transactions engaged in by the Company, (i) would be integrated with the
transactions contemplated by this Agreement for U.S. federal income tax purposes
(an "Integrated Transaction") and (ii) would cause Nortel Networks LLC and the
stockholders of the Company immediately before the transactions contemplated by
this Agreement and any Integrated Transferors (as defined below) not to be in
control (within the meaning of Section 368(c) of the Code) of Newco immediately
after the transactions contemplated by this Agreement. For purposes of this
Agreement, an "Integrated Transferor" includes any Person who receives shares of
Newco in an Integrated Transaction and would be treated as a transferor of
property to Newco in such transaction for purposes of Section 351 of the Code.

         7.15.    Supplemental Indenture. Newco shall enter into a Supplemental
Indenture to the Indenture (the "Indenture") dated as of May 8, 1998, between
the Company and The Bank of New York, required by Article V thereof as a result
of the Merger. Newco shall take appropriate steps to ensure that shares of Newco
Common Stock shall be issued, in accordance with the terms of such Indenture,
upon the conversion after the Effective Time of Notes issued under the
Indenture.

         7.16.    Voting of Shares. The Company shall use reasonable efforts to
obtain, prior to the effectiveness of the Registration Statement, a commitment
from the Company's officers and directors, other than Mr. John Ian Craig, and
AT&T to vote their shares in favor of the Transactions.

        7.17.     Financing. Each of the Company and Newco shall use reasonable
best efforts to close on the financing referenced in the commitment letters
described in Section 6.01(u) above.


                                       44

<PAGE>   48

         7.18.    Restrictions on the Company's Business. The Company shall
provide Nortel Networks with written notice at least ten (10) days prior to the
Company's entering into any agreement or transaction that places a restriction
on the business of the Company (unless it is not able to give ten (10) days
prior notice in which event it will give as much notice as practicable) .

         7.19.    Existing Venture Employees. Company shall provide, at a
minimum, employment terms and conditions that are equal to, in all material
respects, those terms and conditions listed on Section 7.19 of the Company
Disclosure Schedule, and the attachments thereto, to Existing Venture employees.
If the Company, using all reasonable best efforts, is unable to provide any such
term or condition of employment, Nortel Networks and Company shall negotiate in
good faith the replacement of such term or condition. Not less than ten calendar
days prior to the Effective Date, Company shall provide evidence reasonably
satisfactory to Nortel Networks that any term or condition that is not in effect
as of the date hereof shall be in effect as of the Effective Time or, if later,
such time provided in Section 7.19 of the Company Disclosure Schedule.

         7.20.    No Solicitation or Employment by Nortel Networks. Unless
otherwise agreed by Company, during the twelve (12) month period immediately
following the Effective Date, Nortel Networks shall not solicit for employment
or hire any Existing Venture employees or former Existing Venture employees who
voluntarily terminate their employment with Existing Venture during such period;
provided, however, that nothing in this Section 7.20 shall prevent Nortel
Networks from (i) conducting generalized employment searches, by advertisements,
engaging firms to conduct searches, or by other means ("Employment Searches"),
that are not directed at such employees or former employees, or (ii) hiring any
such employees or former employees identified through such Employment Searches.

         7.21.    Remaining Ancillary Agreements. Each of the parties hereto
agrees to negotiate in good faith, prior to the Closing, the following
agreements:

                  (a)    the Sales Representative/Distribution Agreement;
                  (b)    the Transition Services Agreement;
                  (c)    the Supply and Manufacturing Agreement; and
                  (d)    the Development Agreement,

in each case containing terms consistent with the term sheet therefor attached
hereto as part of Exhibit I.

In the event that the parties thereto have not agreed upon the terms of any of
the foregoing agreements by five days before the Outside Closing Date, the
parties to the unresolved agreements shall submit to binding arbitration with
respect solely to the terms of the unresolved agreements in accordance with the
following provisions:

                  (i) The arbitration shall be conducted pursuant to the rules
of the American Arbitration Association ("AAA") before a single arbitrator based
upon written submissions and


                                       45

<PAGE>   49

oral presentations but without any depositions or other discovery. The
arbitrator (A) shall be selected by AAA and shall be experienced in commercial
transactions and arrangements similar to those comprising the subject matter of
the arbitration, and (B) shall have no authority to resolve, or to bind the
parties with respect to, any matter or issue not specifically submitted to him
or her by the parties for arbitration hereunder. The arbitration shall be
conducted in New York, New York.

                  (ii)  The arbitrator shall issue a written decision, which
decision shall be (A) no more favorable to the Existing Venture than the
Existing Venture's most generous written proposal prior to the commencement of
arbitration, and (B) no more favorable to each of the other parties than such
party's most generous written proposal prior to the arbitration.

                  (iii) The arbitrator's decision shall, to the greatest extent
practicable, be based on and incorporate the commercial practices followed by
the relevant parties, with respect to the subject matter being considered by the
arbitrator, prior to commencement of the arbitration.

                  (iv)  Until the arbitrator's decision is rendered, the parties
shall continue conducting business consistent with their commercial practices
referenced in clause (iii) above.

         7.22.    Amendments. Newco shall amend the Newco certificate of
incorporation to contain terms identical to the Company's certificate of
incorporation as in effect on the date hereof except that there shall be
325,000,000 authorized shares of stock and except that Newco's name shall be
changed to "Arris Corporation".

         7.23.    Company Employee Savings Plan. The Company shall register its
Employee Savings Plan (the "Savings Plan") and interests thereunder with the SEC
on an appropriate registration statement under the Securities Act. The Company
shall take such steps as are reasonably necessary to close the Company Stock
Fund under the Savings Plan to any new investments until such registration
statement becomes effective and any required prospectus has been distributed to
all participants under the Savings Plan.

assumptions set forth in such opinion, the Merger constitutes a reorganization

paid or delivered to Nortel Networks, Nortel Networks LLC and their
Subsidiaries. If Nortel Networks, Nortel Networks LLC or their Subsidiaries

Networks LLC or their Subsidiaries shall be obligated to obtain and furnish to

                  (c) Delay. At any time prior to the Effective Time, by Nortel
Networks or the Company, if its respective Board of Directors so determines, in
the event that the Transactions are not consummated by the Outside Closing Date
except to the extent that the failure of the Transactions then to be consummated
arises out of or results from the knowing action or inaction of the party
seeking to terminate pursuant to this Section 9.01(c) which action or inaction
is in violation of its obligations under this Agreement.

                  (d) No Approval.

                      (i)   By the Company or Nortel Networks in the event the
approval of any Governmental Authority required for consummation of the Merger
and the other Transactions shall have been denied by final non-appealable action
of such Governmental Authority.

                      (ii)  By  Nortel Networks in the event any required
approval of a Governmental Authority contains any final nonappealable
conditions, restrictions or requirements which would reasonably be expected to
(A) following the Effective Time, have a Material Adverse Effect on Nortel
Networks or Newco or (B) require Nortel Networks, Nortel Networks LLC, and Newco
to take any action that it is not required to take under Section 7.09(d) hereof.

                      (iii) By the Company or Nortel Networks in the event any
required approval of a Governmental Authority contains any final, nonappealable
conditions, restrictions or requirements which would reasonably be expected to,
following the Effective Time, have a Material Adverse Effect on Newco or require
Newco to take any action that it is not required to take under Section 7.09(d)
hereof.

                      (iv)  By Nortel Networks or the Company in the event the
approval of the Company's stockholders required by Section 8.01(a) herein is not
obtained at the Company Meeting by reason of the failure to obtain the requisite
vote required by Section 8.01(a).

         9.02.    Effect of Termination and Abandonment. In the event of
termination of this Agreement and the abandonment of the Transactions pursuant
to this Article IX, no party to this Agreement (nor any of their respective
officers, directors or agents) shall have any liability or further obligation to
any other party hereunder except that termination shall not relieve a party from
liability for any willful breach of this Agreement.

         9.03.    Survival. All representations, warranties, covenants, and
obligations in this and any other certificate or document delivered pursuant to
this Agreement will survive the Effective Time or, unless this Agreement is
terminated pursuant to Section 9.01(a), the date of termination;


                                       51

<PAGE>   55

provided, however, that in the event of a termination pursuant to Section
9.01(a), the obligations set forth under Sections 4.07 and 10.04 shall survive
such termination.

         9.04.    Right to Indemnification Not Affected by Knowledge. The right
to indemnification, payment of Damages or other remedy based on such
representations, warranties, covenants, and obligations will not be affected by
any investigation conducted with respect to, or any Knowledge acquired (or
capable of being acquired) at any time, whether before or after the execution
and delivery of this Agreement or the Effective Time, with respect to the
accuracy or inaccuracy of or compliance with, any such representation, warranty,
covenant, or obligation (except to the extent that such representation,
warranty, covenant or obligation is expressly qualified by reference to such
Knowledge). The waiver of any condition based on the accuracy of any
representation or warranty, or on the performance of or compliance with any
covenant or obligation, will not affect the right to indemnification, payment of
Damages, or other remedy based on such representations, warranties, covenants,
and obligations.

         9.05.    Indemnification and Payment of Damages by Newco, Transition
and the Company. Newco, Transition and the Company, jointly and severally, will
indemnify and hold harmless Nortel Networks, Nortel Networks LLC and their
controlling persons and Affiliates for, and will pay to such Indemnified Parties
the amount of, any loss, liability, claim, damage (including incidental and
consequential damages), expense (including costs of investigation and defense
and reasonable attorneys' fees) or diminution of value, whether or not involving
a third-party claim (collectively, "Damages"), arising, directly or indirectly,
from or in connection with:

                  (a) any breach of any representation or warranty made by
Newco, Transition or the Company in this Agreement or any other certificate or
document delivered by any of them pursuant to this Agreement;

                  (b) any breach by Newco, Transition or the Company of any
covenant or obligation of any of them in this Agreement; or

                  (c) any claim by any Person for brokerage or finder's fees or
commissions or similar payments based upon any agreement or understanding
alleged to have been made by any such Person with by Newco, Transition or the
Company (or any Person acting on their behalf) in connection with any of the
Transactions.

The remedies provided in this Section 9.05 will not be exclusive of or limit any
other remedies that may be available to Nortel Networks or Nortel Networks LLC
or the other Indemnified Parties.

         9.06.    Indemnification and Payment of Damages by Nortel Networks and
Nortel Networks LLC. Nortel Networks and Nortel Networks LLC, jointly and
severally, will indemnify and hold harmless Newco, Transition and the Company

Indemnified Parties the amount of, any Damages arising, directly or indirectly,

<PAGE>   56

                  (a) any breach of any representation or warranty made Nortel
Networks or Nortel Networks LLC in this Agreement or any other certificate or
document delivered by any of them pursuant to this Agreement;

                  (b) any breach by Nortel Networks or Nortel Networks LLC of
any covenant or obligation of any of them in this Agreement;

                  (c) any claim by any Person for brokerage or finder's fees or
commissions or similar payments based upon any agreement or understanding
alleged to have been made by any such Person with by Nortel Networks or Nortel
Networks LLC (or any Person acting on their behalf) in connection with any of
the Transactions; or

                  (d) if the Closing occurs, 81.25% of the Damages resulting
from any breach of any representation or warranty made by Existing Venture in
this Agreement or any other certificate or document delivered by it pursuant to
this Agreement.

The remedies provided in this Section 9.06 will not be exclusive of or limit any
other remedies that may be available to Newco, Transition or the Company or the
other Indemnified Parties.

         9.07.    Indemnification and Payment of Damages by Existing Venture. If
the Closing does not occur, Existing Venture will indemnify and hold harmless
Newco, Transition and the Company and their controlling persons and Affiliates
for, and will pay to such Indemnified Parties the amount of, 81.25% of any
Damages arising, directly and indirectly, from or in connection with any breach
of any representation or warranty made by Existing Venture in this Agreement or
any certificate or document delivered by it pursuant to this Agreement.

         9.08.    Time Limitations. If the Effective Time occurs, an
Indemnifying Party will have no liability (for indemnification or otherwise)
with respect to any representation or warranty, or covenant or obligation to be
performed and complied with prior to the Effective Time, other than those in
Sections 6.01(b), 6.01(m), 6.01(o), 6.01(q), 6.02(i), and 6.02(j) unless on or
before the second anniversary of the Effective Date the Indemnified Party
notifies Indemnifying Party of a claim specifying the factual basis of that
claim in reasonable detail to the extent then known by the Indemnified Party; a
claim with respect to Section 6.01(b), 6.01(m), 6.01(o), 6.01(q), 6.02(i) and
6.02(j), or a claim for indemnification or reimbursement not based upon any
representation or warranty or any covenant or obligation to be performed and
complied with prior to the Closing Date, may be made at any time.

         9.09.    Limitations on Amount - Newco, Transition, and the Company.
Newco, Transition and the Company will have no liability (for indemnification
or, except with respect to claims based on fraud, otherwise) with respect to the
matters described in 9.05 until the total of all Damages with respect to such
matters exceeds $10,000,000 (at which point Newco, Transition and the Company
shall become liable for the aggregate Damages and not just the amount in excess
of $10,000,000). However, this Section 9.09 will not apply to any intentional
breach by


                                       53

<PAGE>   57

Newco, Transition or the Company of any covenant or obligation, and Newco,
Transition and the Company will be jointly and severally liable for all Damages
with respect to such breaches.

         9.10.    Limitations on Amount - Nortel Networks and Nortel Networks
LLC. Nortel Networks and Nortel Networks LLC will have no liability (for
indemnification or, except with respect to claims based on fraud, otherwise)
with respect to the matters described in Section 9.06 until the total of all
Damages with respect to such matters exceeds $10,000,000 (at which point Nortel
Networks and Nortel Networks LLC shall become liable for the aggregate Damages
and not just the amount in excess of $10,000,000); provided that the aggregate
amount payable (i) by Nortel Networks and/or Nortel Networks LLC pursuant to
Section 9.06(d) and/or (ii) by the Existing Venture pursuant to Section 9.07 (in
any combination) shall in no event exceed $215,000,000. However, this Section
9.10 will not apply to any intentional breach by either Nortel Networks or
Nortel Networks LLC of any covenant or obligation, and Nortel Networks or Nortel
Networks LLC will be jointly and severally liable for all Damages with respect
to such breaches.

         9.11.    Limitations on Amount--Existing Venture. Neither Nortel
Networks (or any of its Subsidiaries) nor the Existing Venture will have any
liability (for indemnification or, except with respect to claims based on fraud,
otherwise) with respect to matters described in Section 9.06(d) or 9.07 until
the total of Damages with respect to such matters exceeds $10,000,000 (at which
point the Existing Venture shall become liable for the aggregate Damages and not
just the amount in excess of $10,000,000); provided that the aggregate amount
payable (i) by Nortel Networks and/or Nortel Networks LLC pursuant to Section
9.06(e) and/or (ii) by the Existing Venture pursuant to Section 9.07 (in any
combination) shall in no event exceed $215,000,000. However, this Section 9.11
will not apply to any intentional breach by Existing Venture of any covenant or
obligation.

         9.12.    Procedure for Indemnification - Third Party Claims.

                  (a) Promptly after receipt by an Indemnified Party under
Section 9.05 or 9.06 of notice of the making of any claim or the commencement of
any proceeding against it, such Indemnified Party will, if a claim is to be made
against an Indemnifying Party under such Section, give notice to the
Indemnifying Party of such claim or proceeding, but the failure to notify the
Indemnifying Party will not relieve the Indemnifying Party of any liability that
it may have to any Indemnified Party, except to the extent that the Indemnifying
Party demonstrates that the defense of such action is prejudiced by the
Indemnifying Party's failure to give such notice.

                  (b) If any proceeding referred to in Section 9.10(a) is
brought against an Indemnified Party and it gives notice to the Indemnifying
Party of the commencement of such proceeding, the Indemnifying Party will be
entitled to participate in such proceeding and, to the extent that it wishes, to
assume the defense of such proceeding with counsel satisfactory to the
Indemnified Party and, after notice from the Indemnifying Party to the
Indemnified Party of its election to assume the defense of such proceeding, the
Indemnifying Party will not, as long as it diligently conducts such defense, be
liable to the Indemnified Party under Section 9.05 or 9.06


                                       54

<PAGE>   58

for any fees of other counsel or any other expenses with respect to the defense
of such proceeding, in each case subsequently incurred by the Indemnified Party
in connection with the defense of such proceeding, other than reasonable costs
of investigation. If the Indemnifying Party assumes the defense of a proceeding,
(i) it will be conclusively established for purposes of this Agreement that the
claims made in that proceeding are within the scope of and subject to
indemnification; (ii) no compromise or settlement of such claims may be effected
by the Indemnifying Party without the Indemnified Party's consent unless (A)
there is no finding or admission of any violation of applicable law or any
violation of the rights of any Person and no effect on any other claims that may
be made against the Indemnified Party, and (B) the sole relief provided is
monetary Damages that are paid in full by the Indemnifying Party; and (iii) the
Indemnified Party will have no liability with respect to any compromise or
settlement of such claims effected without its consent. If notice is given to an
Indemnifying Party of the commencement of any proceeding and the Indemnifying
Party does not, within ten days after the Indemnified Party's notice is given,
give notice to the Indemnified Party of its election to assume the defense of
such proceeding, the Indemnifying Party will be bound by any determination made
in such proceeding or any compromise or settlement effected by the Indemnified
Party.

                  (c) Notwithstanding the foregoing, if an Indemnified Party
determines in good faith that there is a reasonable probability that a
proceeding may adversely affect it or its Affiliates other than as a result of
monetary Damages for which it would be entitled to indemnification under this
Agreement, the Indemnified Party may, by notice to the Indemnifying Party,
assume the exclusive right to defend, compromise, or settle such proceeding, in
all cases at the expense of Indemnifying Party, but the Indemnifying Party will
not be bound by any determination of a proceeding so defended or any compromise
or settlement effected without its consent (which may not be unreasonably
withheld).

                  (d) The parties hereto hereby consent to the non-exclusive
jurisdiction of any court in which a proceeding is brought against any
Indemnified Party for purposes of any claim that an Indemnified Party may have
under this Agreement with respect to such proceeding or the matters alleged
therein, and agree that process may be served on their with respect to such a
claim anywhere in the world.

         9.13.    Procedure for Indemnification - Other Claims. A claim for
indemnification for any matter not involving a third-party claim may be asserted
by notice to the party from whom indemnification is sought.

                                    ARTICLE X
                                  MISCELLANEOUS

         10.01.   Amendment; Extension; Waiver.

                  (a) Subject to compliance with applicable law, this Agreement
may be amended by the parties hereto, by action taken or authorized by their
respective Boards of Directors, at any time before or after approval of the
matters presented in connection with the


                                       55

<PAGE>   59

Merger by the stockholders of the Company; provided, however, that after any
approval of the Transactions contemplated by this Agreement by the stockholders
of the Company, there may not be, without further approval of such stockholders,
any amendment of this Agreement which by law requires such further approval by
such stockholders. This Agreement may not be amended except by an instrument in
writing signed on behalf of each of the parties hereto.

                  (b) Prior to the Effective Time, the parties hereto, Newco,
the Company and Transition, as one party, and Nortel Networks and Nortel
Networks LLC, as one party, by action taken or authorized by their respective
Boards of Directors or Managing Member, as the case may be, may, to the extent
legally allowed, (i) extend the time for the performance of any of the
obligations or other acts of the other party, (ii) waive any inaccuracies in the
representations and warranties of the other party contained herein or in any
document delivered pursuant hereto and (iii) waive compliance by the other party
with any of the agreements or conditions contained herein. Any agreement on the
part of a party hereto to any such extension or waiver shall be valid only if
set forth in a written instrument signed on behalf of such party, but such
extension or waiver or failure to insist on strict compliance with an
obligation, covenant, agreement or condition shall not operate as a waiver of,
or estoppel with respect to, any subsequent or other failure.

         10.02.   Counterparts. This Agreement may be executed in one or more
counterparts, each of which when executed shall be deemed to constitute an
original but all of which when taken together shall constitute one and the same
instrument.

         10.03.   Governing Law. This Agreement shall be governed by, and
interpreted in accordance with, the laws of the State of Delaware, without
regard to the conflict of law principles thereof.

         10.04.   Expenses. Except as otherwise provided herein or in the
Registration Rights Agreement, each party hereto will bear all expenses incurred
by it in connection with this Agreement and the transactions contemplated
hereby, except that SEC filing fees payable to the extent necessary to
consummate the Transactions plus up to $75,000 of the printing and mailing
expenses relating to the Transactions (specifically excluding, for the avoidance
of doubt, any exercise of rights granted under the Registration Rights
Agreement) actually and reasonably incurred and paid by the Company and its
Affiliates shall be shared equally between the Company and Nortel Networks, and
any such expenses and fees in excess of the above amount shall be borne solely
by the Company.

         10.05.   Notices. All notices, requests and other communications
hereunder to a party shall be in writing and shall be deemed given if personally
delivered, telecopied (with confirmation) or three Business Days after being
mailed by registered or certified mail (return receipt requested) or one
Business Day after being delivered by overnight courier to such party at its
address set forth below or such other address as such party may specify by
notice to the parties hereto.

         10.06.   Entire Understanding. This Agreement (including the Disclosure
Schedules), the Ancillary Agreements and the Confidentiality Agreement represent
the entire understanding of the parties hereto with reference to the
transactions contemplated hereby and thereby supersede


                                       57

<PAGE>   61

any and all other oral or written agreements (other than the Confidentiality
Agreement) heretofore made.

         10.07.   Assignment; No Third Party Beneficiaries. Neither this
Agreement, nor any of the rights, interests or obligations shall be assigned by
any of the parties hereto (whether by operation of law or otherwise) without the
prior written consent of the other parties; provided, however, that (i) Nortel
Networks LLC may, at any time prior to the Effective Time, transfer its Interest
(as such term is defined in the Existing Venture Operating Agreement) to any
other direct or indirect wholly-owned Subsidiary of Nortel Networks, with no
need for consent or approval of any other party hereto (other than Nortel
Networks), and (ii) in the event of such transfer, the transferee of the
Interest shall be substituted for Nortel Networks LLC herein and in each
Ancillary Agreement to which Nortel Networks LLC is, or is intended to be, a
party, as if such transferee were an original party hereto and thereto, mutatis
mutandis. Subject to the preceding sentence, this Agreement will be binding
upon, inure to the benefit of and be enforceable by the parties and their
respective successors and assigns. Nothing in this Agreement expressed or
implied, is intended to confer upon any person, other than the parties hereto or
their respective successors, any rights, remedies, obligations or liabilities
under or by reason of this Agreement.

         10.08.   Disclosure Schedules.

                  (a) The inclusion of any matter on the disclosures made on the
Company and Nortel Networks Schedules (collectively, the "Disclosure Schedules")
with respect to any representation or warranty will not be deemed an admission
by any party that such listed matter is material or that such listed matter has
or would have a Material Adverse Effect on the Company, Newco or Transition or a
Material Adverse Effect on Nortel Networks or Nortel Networks LLC, as
applicable.

                  (b) The Disclosure Schedules shall be deemed to constitute an
integral part of this Agreement and to modify the respective representations,
warranties, covenants or agreements of the parties contained herein to the
extent that such representations, warranties, covenants or agreements expressly
refer to the applicable Disclosure Schedule. Anything to the contrary contained
herein or in the Disclosure Schedules notwithstanding, any and all statements,
representations, warranties, or disclosures set forth in the Disclosure
Schedules delivered on or before the date hereof shall be deemed to have been
made on and as of the date hereof. From time to time prior to the Closing, the
parties shall promptly supplement or amend the Disclosure Schedules with respect
to any matter, condition or occurrence hereafter arising which, if existing or
occurring at the date of this Agreement, would have been required to be listed
or described in the Disclosure Schedules. No supplement or amendment shall be
deemed to cure any breach or any representation or warranty made in this
Agreement or have any effect for the purpose of determining satisfaction of the
conditions set forth in this Agreement.

         10.09.   Interpretation. When a reference is made in this Agreement to
Articles, Sections, Exhibits or Disclosure Schedules, such reference shall be to
and Article or Section of, or Exhibit


                                       58

<PAGE>   62

or Disclosure Schedule to, this Agreement unless otherwise indicated. The table
of contents and headings contained in this Agreement are for reference purposes
only and are not part of this Agreement. Whenever the words "include",
"includes" or "including" are used in this Agreement, they shall be deemed to be
followed by the words "without limitation". Any reference to "herein" or
"hereof" or similar terms shall refer to the agreement as a whole rather than to
the individual paragraph, Section or Article.

         10.10.   Severability. Any term or provision of this Agreement which is
invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be
ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, the provision shall be interpreted
to be only so broad as it is enforceable.
