NORTEL NETWORKS LIMITED

RESTRICTED STOCK UNIT PLAN



|1. |  | BACKGROUND; PURPOSE OF THE PLAN
|-- |  | -------------------------------

The Nortel Networks Limited Restricted Stock Unit Plan has been amended
and restated to reflect the transactions contemplated by the plan of
arrangement (the Plan of Arrangement) described in the Amended and Restated
Arrangement Agreement, made as of January 26, 2000, as amended and restated
March 13, 2000, among BCE Inc., Nortel Networks Corporation, New Nortel Inc.
and the other parties thereto. In connection with the Plan of Arrangement, New
Nortel Inc. acquired from the holders of the common shares (other than BCE Inc.
and its affiliates) of Nortel Networks Corporation all of the Nortel Networks
Corporation common shares then held by such shareholders in exchange for an
equal number of common shares of New Nortel Inc. and each shareholder of BCE
Inc. received approximately 0.78 common shares of New Nortel Inc. for each
common share of BCE Inc. then held by such BCE shareholder. On the effective
date of the Plan of Arrangement, the common shares of New Nortel Inc. were
listed on the New York Stock Exchange and The Toronto Stock Exchange in
substitution for the common shares of Nortel Networks Corporation. As part of
the Plan of Arrangement, Nortel Networks Corporation changed its name to Nortel
Networks Limited (Nortel Limited or the Corporation) and New Nortel Inc.
changed its name to Nortel Networks Corporation (Nortel Networks).

In connection with and effective as of May 1, 2000, the effective date of
the Plan of Arrangement (the Restatement Effective Date), awards granted or
to be granted under the Plan and the shares subject to the Plan were adjusted
and relate to the common shares of Nortel Networks. In all other respects, the
terms and provisions of the Plan were reaffirmed, as stated at that time.

The purpose of the Plan is to promote the long term success of Nortel
Networks by providing for the payment of performance bonuses to Designated
Employees in the form of Shares or calculated by reference to the Share Price.
The Plan is designed to encourage Designated Employees to acquire a proprietary
interest in Nortel Networks through ownership of Shares or interests in Shares,
to provide them with additional incentive to further the growth and development
of Nortel Networks, to encourage them to remain in the employment of Nortel
Networks and to assist Nortel Networks in attracting individuals with
experience and ability.

otherwise determined by the Committee, a Participant may elect, by notice to

| | (ii) |  | except as may be otherwise provided under the terms
of any other employee benefit plan approved by the Board of
Directors, each Participant who has received any such Grant (or
any applicable portion thereof) shall, on the applicable
Release Date which would have applied had the Change in Control
not occurred, be entitled to receive from the Corporation, in
full settlement of the RSUs covered by such Grant (or
applicable portion thereof), one of the following, at the sole
discretion of the Committee:



| | (x) |  | a cash payment equal to the Special
Value (as defined below) for each Covered RSU (as

##### 



The term Special Value shall mean an amount with respect to each Covered
RSU determined as follows:



| | (i)  |  | if any Shares are sold as part of the transaction
constituting the Change in Control, the Special Value shall
equal the weighted average of the prices paid for those Shares
by the acquiror, provided that if any portion of the
consideration paid for such Shares by the acquiror is paid in
property other than cash, the Board of Directors (as
constituted immediately prior to the CIC Date) shall determine
the fair market value of such property as of the CIC Date for
purposes of determining the Special Value under this paragraph
(f); and
| | ---- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|
| | (ii) |  | if no Shares are sold as part of the transaction
constituting the Change in Control, the Special Value shall
equal the arithmetic average of the closing prices for the
Shares on The Toronto Stock Exchange for the 20 trading days
immediately preceding the CIC Date.                                                                                                                                                                                                                                                                                 

The term CIC Share shall mean the following with respect to each Covered
RSU:



| | (i)  |  | the sum of: (A) the number of Consideration
Shares (as defined below), rounded to the nearest whole
number, that is equal to the product of (x) one Share
multiplied by (y) the number of Consideration Shares (as
defined below) received by the shareholders of Nortel Networks
in respect of one Share, if, in connection with the
transaction constituting the Change in Control, the
shareholders of Nortel Networks exchange their Shares for, or
otherwise convert their Shares into, shares of equity
securities of the acquiror (or its direct or indirect parent)
(such shares of equity securities, the Consideration
Shares); and (B) the amount, if any, that is equal to the
product of (x) one Share multiplied by (y) any cash or other
property, the fair market value of which shall be determined
by the Board of Directors (as constituted immediately prior to
the CIC Date), received by the shareholders of Nortel Networks
in respect of one Share, in connection with such transaction;
and

|
| | (ii) |  | in the case of all other transactions
constituting the Change in Control, one Share, as adjusted
pursuant to Section 7 hereof in connection with such
transaction, if applicable;                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     

and, in each case, as further adjusted pursuant to Section 7, if applicable, in
respect of covered events occurring after such Change in Control.

The term Covered RSU shall mean, with respect to each Grant (or portion
thereof) that is outstanding on the CIC Date, the number of RSUs that would
have been issued to a Participant on the applicable Release Date and settled in
the form of RSU Shares had (x) the Participant continued in the employment of
Nortel Networks Companies until such Release Date and (y) all Performance
Criteria, if any, applicable to such Grant (or any applicable portion

thereof) (in all cases, determined without regard to the occurrence of the
Change in Control) had been met (but not exceeded) during the applicable
Performance Period or Performance Segment, if any.



| | (g) |  | Non-Transferability
| | --- |  | -------------------

The rights or interests of a Participant under the Plan shall not be
assignable or transferable, otherwise than by will or the laws governing the
devolution of property in the event of death and such rights or interests shall
not be encumbered.



| | (h) |  | RSUs Not Shares
| | --- |  | ---------------

Under no circumstances shall a Grant or an RSU be considered a Share, nor
shall a Grant or an RSU entitle any Participant to the exercise of voting
rights, the receipt of dividends or the exercise of any other rights attaching
to ownership of a Share, until delivery of an RSU Share in settlement of such
RSU in accordance with the terms of the Plan. Notwithstanding the foregoing,
in the event that Shares are purchased and held for the benefit of a
Participant prior to delivery of RSU Shares in settlement of any RSUs, the
Committee may determine the extent to which a Participant may be entitled to
exercise any voting rights, receive dividends or exercise any other rights
attaching to ownership of such Shares.



| | (i) |  | RSU Shares Fully Paid
| | --- |  | ---------------------

RSU Shares, if issued by Nortel Networks to settle RSUs under the Plan,
shall be considered fully paid in consideration of past service that is no less
in value than the fair equivalent of the money Nortel Networks would have
received if the RSU Shares had been issued for money.



|7. |  | EFFECTS OF ALTERATION OF SHARE CAPITAL
|-- |  | --------------------------------------

In the event that:



| | (a) |  | a dividend shall be declared upon the Shares
payable in Shares of Nortel Networks;                                                                                                                                                                                                                                                     
| | --- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|
| | (b) |  | the outstanding Shares shall be changed into or
exchanged for a different number or kind of shares or other
securities of Nortel Networks or of another corporation,
whether through an arrangement, plan of arrangement,
amalgamation or other similar statutory procedure, or a share
recapitalization, subdivision or consolidation;
|
| | (c) |  | there shall be any change, other than those
specified in paragraphs (a) and (b) of this Section, in the
number or kind of outstanding Shares or of any shares or other
securities into which such Shares shall have been changed or
for which they shall have been exchanged; or                                                       
|
| | (d) |  | there shall be a distribution of assets or shares
to shareholders of Nortel Networks out of the ordinary course
of business,

##### 



then, if the Board of Directors shall in its sole discretion determine that
such change equitably requires an adjustment in the number of RSUs with respect
to which Grants may be made pursuant to the Plan but not yet covered by Grants,
of the RSUs then covered by Grants, of the RSUs generally available for Grants
under the Plan and of the RSUs available for Grants under the Plan in any
calendar year, such adjustment shall be made by the Board of Directors and
shall be effective and binding for all purposes.

No adjustment provided for in this Section shall entitle a Participant to
be allocated a fractional RSU, or receive a fractional RSU Share or any payment
in lieu thereof, and the total adjustment with respect to each RSU shall be
limited accordingly.



|8. |  | AMENDMENT AND TERMINATION
|-- |  | -------------------------

The Board of Directors may from time to time amend, suspend or terminate
the Plan in whole or in part. The Committee may from time to time amend the
terms of Grants made under the Plan, subject to confirmation by the Board of
Directors and the obtaining of any required regulatory or other approvals and,
if any such amendment will materially adversely affect the rights of a
Participant with respect to a Grant, the obtaining of the written consent of
such Participant to such amendment. Notwithstanding the foregoing, (i) the
obtaining of the written consent of any Participant to an amendment which
materially adversely affects the rights of such Participant with respect to a
Grant shall not be required if such amendment is required to comply with
applicable laws, regulations, rules, orders of governmental or regulatory
authorities or the requirements of any stock exchange on which Shares of Nortel
Networks are listed and (ii) no amendment may be made to paragraph (f) of
Section 6 of the Plan or to the defined terms referred to in paragraph (f) of
Section 6 on or after the CIC Date.



|9. |  | MISCELLANEOUS PROVISIONS
|-- |  | ------------------------

Participation in the Plan by a Designated Employee is voluntary. No
employee shall have any claim or right to receive Grants under the Plan, and
the Grant and issuance of RSUs under the Plan shall not be construed as giving
a Participant any right to continue in the employment of Nortel Networks
Companies or to receive any additional Grants, or affect the right of Nortel
Networks Companies to terminate the employment of any Participant. Unless the
Committee determines otherwise, no notice of termination or payment in lieu
thereof shall extend the period of employment for purposes of this Plan.

The Committee and/or the Administrator may adopt and apply rules that in
its opinion will ensure that Nortel Networks Companies will be able to comply
with applicable provisions of any federal, provincial, state or local law
relating to the withholding of tax, including on the amount, if any, included
in income of a Participant. Nortel Networks Companies or the Administrator may
withhold from any amount payable to a Participant, either under this Plan, or
otherwise, such amount as may be necessary so as to ensure that Nortel Networks
Companies will be able to comply with applicable provisions of any federal,
provincial, state or local law relating to withholding of tax or other required
deductions, including on the amount, if any, includable in the income of a
Participant. Nortel Networks Companies or the Administrator shall, in this
connection, have the right in its discretion to satisfy any such withholding
tax liability by retaining or acquiring any Shares which would otherwise be

13



---



##### 



issued or provided to a Participant hereunder, or withholding any portion
of any cash amount payable to a Participant hereunder. Nortel Networks
Companies or the Administrator shall also have the right to withhold the
delivery of any RSUs and RSU Shares and any cash payment payable to a
Participant hereunder unless and until such Participant pays to Nortel Networks
Companies a sum sufficient to indemnify Nortel Networks Companies for any
liability to withhold tax in respect of the amounts included in the income of
such Participant as a result of the settlement of RSUs under this Plan, to the
extent that such tax is not otherwise being withheld from payments to such
Participant by Nortel Networks Companies or the Administrator.

Participation in the Plan by any Participant shall be construed as
acceptance of the terms and conditions of the Plan by the Participant and as to
the Participants agreement to be bound thereby. The Plan shall be construed
in accordance with and governed by the laws of the Province of Ontario.

In this Plan, whenever the context so requires, the masculine gender
includes the feminine gender and a singular number includes the plural number.

Directors. Any amendments to the Plan shall become effective upon their
