(7) calendar days following your execution of this document to revoke this Agreement by written notice. To be valid, the letter of revocation must be received by ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇ (“me”) at Nortel Networks, ▇▇▇▇ ▇. ▇▇▇▇▇▇ ▇▇▇▇-▇▇▇▇▇▇ ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇, not later than the close of business seven (7) calendar days after you sign this Agreement. The terms and conditions of this Agreement shall become operative seven (7) days after you execute and deliver this Agreement to me, provided that you are in compliance with all terms and conditions of this Agreement and that you have not revoked this Agreement pursuant to the provisions set forth above in this paragraph.

4. The Corporation will provide you the applicable payments and benefits as set forth in paragraphs 5 and 8 of this Agreement. Conditional only upon (i) your compliance with all terms and conditions of this Agreement; and (ii) you not revoking this Agreement pursuant to paragraph 3 above, the Corporation will:

	(a)		pay you the equivalent of two (2) years’ base salary as a salary continuance benefit commencing with a lump sum payment of Two Hundred Ninety-Four Thousand Nine Hundred Ninety-Nine and 90/100 ($294,999.90) United States Dollars (“Dollars”) to be made on June 24, 2006 and equal bi-weekly payments thereafter of Twenty-Two Thousand Six Hundred Ninety-Two and 30/100 ($22,692.30) Dollars through and including December 28, 2007 (collectively, “Severance Pay”). The period during which your Severance Pay is calculated, from December 24, 2005 through December 28, 2007, is referred to in this Agreement as the “Severance Period”. Your Severance Pay is an individually negotiated amount to be paid in a different manner than and in lieu of any severance allowance benefit payable under the Nortel Networks Enhanced Severance Allowance Plan. By this Agreement you expressly waive any right to receive a benefit under the terms of the Nortel Networks Enhanced Severance Allowance Plan;
	(b)		allow you to elect to: (i) continue during the Severance Period, all group life insurance (basic and optional employee and optional spouse and dependent), health coverages (medical, dental, vision, hearing, Employee Assistance Program and Health Care Reimbursement Account (“HCRA”) and AD&D coverage in which you and your covered eligible dependents, if any, are enrolled on the Employment Termination Date pursuant to the terms and conditions of such coverages; or (ii) revoke all such coverages. If you elect (i), your coverages will continue at the active employee contribution rate, which shall be deducted from Severance Pay set forth in paragraph 4(a). The Corporation shall have the right to change coverages, upon notice provided to

you in the same manner as to employees generally, only to the extent that it is generally changing its coverages for senior executive employees occupying positions similar to that you occupied in your most senior position with the Corporation. Upon termination of coverages, only continued health coverage will be offered, as required by the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”), for a period generally extending for 18 months from your Employment Termination Date, minus the period of coverage at active contribution rates during the Severance Period. If you elect (ii), your life and AD&D coverages will terminate effective 12:01 a.m. on January 1, 2006 and your health coverages, with the exception of HCRA, will terminate at the end of the month in which your employment relationship ceases (December, 2005), with an opportunity for continued health coverage under COBRA. If you decline the opportunity to continue HCRA coverage under COBRA, only eligible expenses incurred on or prior to the Employment Termination Date will be considered for reimbursement. Irrespective if you select (i) or (ii) above, at the time your group life insurance coverages terminate, you may convert appropriate coverages to applicable individual policies. AD&D cannot be converted to an individual policy. Please make your election in the space provided at the end of this Agreement concerning your decision to elect or decline the benefits set forth in this paragraph 4(b);

	(c)		consider you ineligible for consideration for any future grant(s) of stock options or Restricted Stock Units (RSUs).

Your right, if any, to exercise any vested Nortel Networks stock options or RSUs after the Employment Termination Date (including during the Severance Period) will be determined in accordance with the provisions of the stock option or RSU plan under which the stock options or RSUs were granted and the instrument of grant evidencing the options or RSUs;
	(d)		make available to you during the Severance Period, should you elect, executive outplacement services to assist you in securing new employment and pay the professional fees for such services as are reasonably incurred;
	(e)		with respect to any monies or monetary equivalents to be paid hereunder, in its reasonable discretion withhold appropriate amounts concerning any and all applicable federal, state or local tax withholding;

5. The following payments and benefits shall be provided to you by the Corporation, as applicable, without the requirement that you sign and comply with this Agreement:

The Corporation’s Corporate Procedure 206.01 states that “all documents, messages or data composed, sent, or received through the network of Nortel Networks in any form are and remain at all times the property of Nortel Networks”. In addition, all work product that you have produced during your employment with the Corporation is the property of the Corporation.

You are aware that Nortel Networks has received a formal order of investigation from the United States Securities and Exchange Commission (“SEC”) that requires the preservation and collection and disclosure of certain Information to the SEC.

The Information will be used by the Corporation for general business purposes and may also be provided by the Corporation to regulatory authorities in response to their requests or disclosed in any relevant private litigation to which the Corporation is a party. Also, the Information may be used by and provided to other entities within the Nortel Networks group and/or the Corporation’s external advisors. In some instances, the recipients of this Information will be located outside your geographic area. To the extent that the Information contains any personal information, you consent to the collection, transfer and disclosure of that information by the Corporation to Nortel Networks entities, third parties and regulatory authorities within and outside of your geographic area for the purposes set out above.

	(a)		The Corporation shall indemnify you, and advance any reasonable legal fees and expenses, to the extent permitted by, and in accordance with section 124 of the Canada Business Corporations Act (the “CBCA”) and the Corporation’s By-Laws (the “By-Laws”). You shall repay such fees and expenses if and to the extent it is determined that you do not fulfill the conditions set forth in subsection 124(3) of the CBCA or the By-Laws.
	(b)		Subject to and without limiting the foregoing, the Corporation’s legal counsel will represent you in respect of any civil, criminal, administrative, investigative (including any internal investigation or independent review being conducted by the Corporation’s Board of Directors or a Committee thereof) or other proceeding in Canada, the United States or other applicable jurisdiction in which you are involved (including as a witness) because of your association with the Corporation (hereafter, a “Matter”).

▇▇. ▇▇▇▇▇▇ ▇▇▇▇▇
February 21, 2006

and actual legal expenses in that Matter provided you agree that you will not settle the Matter, retain defense counsel or expert witnesses or consultants, or incur any non-normal course defense costs without obtaining the Corporation’s prior consent, which consent will not be unreasonably withheld.

(c) With respect to the subject matter of (1) the investigation being conducted by the United States Securities and Exchange Commission (“SEC”) pursuant to formal order of private investigation in In the Matter of Nortel Networks Corporation (SEC File No. H-9799); (2) the related investigation being conducted by the Ontario Securities Commission; and (3) any other investigation by any law enforcement authority, governmental body or self-regulatory organization in connection with any fact, circumstance, situation, transaction, event or other source of liability related to the subject matter referenced in the immediately foregoing items (1) and (2) or referenced in the Corporation’s October 23, 2003 8K filing with the SEC (all of the foregoing, collectively, the “Investigation”), you have retained separate counsel independent of any duty to the Corporation (▇▇▇▇▇▇ & ▇▇▇▇▇▇▇ LLP and Fasken ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ LLP) and the Corporation will continue to advance monies to pay your reasonable legal fees and expenses associated with the Investigation and all proceedings such as may arise from it (collectively, the “Investigation Indemnified Matters”). For clarification, Investigation Indemnified Matters include civil litigation of related subject matter. The Corporation acknowledges that the requirement set forth in this paragraph not to settle any Matter without the Corporation’s prior consent does not apply to any Investigation Indemnified Matters. The Corporation’s determination to advance such reasonable legal fees and expenses is subject to section 124 of the CBCA and the By-Laws and you shall repay such fees and expenses if it is determined that you do not fulfill the conditions set forth in subsection 124(3) of the CBCA or the By-Laws. The Corporation will also timely provide to your counsel reasonable access to or copies of any and all documents you generated and/or received during the time period covered by the Investigation, and/or as are relevant to any Investigation Indemnified Matter, as your counsel reasonably requests.

9. With the exception of the Application filed in Ontario Superior Court of Justice in the matter of Indiana Electrical Workers Pension Trust Fund IBEW and Laborers 100 and 397 Pension Fund v.
