Dear Xxxxx:

This letter (“Agreement”) records the arrangements between you and Nortel Networks Limited concerning the cessation of your employment. The Agreement shall bind and inure to the benefit of each party and their respective heirs, successors and assigns.

1.		As used in this Agreement, the term “Corporation” shall mean Nortel Networks Corporation, its subsidiaries and affiliates, their successors and assigns, and all of their past and present officers, directors, employees and agents (in their individual and representative capacities), in every case, individually and collectively.
2.		Effective as of the close of business on April 30, 2007, your active employment relationship with the Corporation will cease (the “Employment Termination Date”). However, it is agreed and understood that as of the close of business on March 31, 2007, you will no longer be expected to perform your current duties or responsibilities on behalf of the Corporation (and you shall not be held responsible for the performance of such duties and responsibilities) and you are not required to come into the office after such date. All previous external responsibilities which you had will be assumed by a person designated by the Corporation, including any participation in industry or other associations representing the Corporation. You cease to act as an officer and/or director of the Corporation and any of the Corporation’s subsidiaries and affiliates on April 30, 2007, and the Corporation will take all necessary steps to remove you from all such positions.

3.		You understand and agree that your designation of Reporting Insider pursuant to Corporate Policy 320.28 of the Corporation (and under applicable Canadian/U.S. securities legislation for Reporting Insiders), shall cease effective 12:01 a.m. on May 1, 2007. Notwithstanding the fact that you no longer have this designation, if you are in possession of material non-public information relating to the Corporation, you are prohibited from trading in securities of the Corporation (or informing another person of the material non-public information) in accordance with applicable laws. You further understand that you are required to amend your insider profile within 10 days of April 30, 2007 on the Canadian System for Electronic Disclosure by Insiders (SEDI) to indicate that you are no longer a Reporting Insider of the Corporation.

4.		Conditional upon your compliance with all terms and conditions of this Agreement, the Corporation shall:

	(a)		pay you the sum of US$ 24,038.46 bi-weekly, converted to Canadian currency in the same manner as you were paid immediately prior to the termination of your active employment, less applicable deductions, commencing on May 1, 2007 and terminating April 30, 2009 (“Salary Continuation Period”). The first such payment shall be made on the Corporation’s next regular payroll date following the Employment Termination Date and shall include all bi-weekly payments accrued to that date;
	(b)		pay you, on or before the next regular payroll date following the Employment Termination Date, a lump sum amount equivalent to three (3) weeks of base salary representing all of your current accrued but unused vacation benefit, with no further vacation accrual subsequent to April 30, 2007;
	(c)		consider you eligible to receive an incentive award payment under the 2006 SUCCESS Incentive Plan (the “Plan”) as contemplated by the Plan. Any payment under the Plan will be determined by the Corporation based on the terms and conditions of the Plan applicable to you as of the date hereof, and will be made using an Individual Performance Factor of 1.0. Eligibility shall not be construed as a right to such payment, and any such payment will be made to you in a lump sum on the date that any incentive award payment is made by the Corporation to employees generally under the terms of the Plan;
	(d)		continue your participation during the Salary Continuation Period, subject to the provisions of the applicable plans, in group medical, life insurance and

Your right, if any, to exercise any vested stock options or to receive common shares of the Corporation in settlement of any vested RSUs after your active employment relationship with the Corporation ceases (including during the Salary Continuation 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 evidencing the options or RSUs. Your right to receive common shares of the Corporation in settlement of PSUs previously granted to you shall be determined in accordance with the provisions of the PSU plan under which PSUs were awarded and the instrument evidencing the award. To the extent applicable, it is confirmed that you meet the definition of retirement under the Nortel Networks Corporation 2005 Stock Incentive Plan;
