Nortel announces US$1.3 Billion Financing Commitment

* US$1.3 Billion Credit Facility to Refinance Bond Maturity
* Cash Balance of US$3.0 Billion as at December 31, 2005
* Timing of Fourth Quarter & Full Year 2005 Financial Reporting.

FEBRUARY 01, 2006, TORONTO - Nortel* Networks Corporation [NYSE/TSX: NT] announced that it and the Company’s indirect subsidiary, Nortel Networks Inc. (“NNI”), have entered into binding commitments for a new one year credit facility in the aggregate principal amount of US$1.3 billion arranged by J.P. Morgan Securities Inc. and Citigroup Corporate and Investment Banking, or their affiliates.

Subject to the terms and conditions of the commitments, JPMorgan Chase Bank, N.A., Citigroup Corporate and Investment Banking, Royal Bank of Canada and Export Development Canada have agreed to provide NNI with a credit facility in the aggregate amount of US$1.3 billion, consisting of (i) a senior secured one-year term loan facility in the amount of US$850 million and (ii) a senior unsecured one-year term loan facility in the amount of US$450 million.

This new facility, which would mature in February 2007, will be used to refinance the outstanding US$1.275 billion aggregate principal amount of 6.125% Notes due February 15, 2006 of the Company’s principal operating subsidiary, Nortel Networks Limited (“NNL”).

The Company has elected to proceed with this financing while it continues to pursue important objectives, including the ongoing mediation efforts relating to two of its significant pending class action lawsuits in the United States. As the Company has previously disclosed, it cannot predict whether such mediation efforts will result in achieving a global settlement encompassing these two actions. For additional information about these actions, see the Company’s periodic and current reports filed with the United States Securities and Exchange Commission. The Company continues to evaluate its long term financing alternatives and expects to access the capital markets at the appropriate time.

The secured loan would be secured by a first priority lien on substantially all of the U.S. and Canadian assets of the Company, NNL and NNI. NNL’s US$200 million 6.875% Notes due June 15, 2023 and amounts outstanding under NNL’s US$750 million EDC performance-related support facility would be equally and ratably secured with the secured loan. NNI’s obligations under the secured loan would be guaranteed by the Company and NNL, and amounts outstanding under NNL’s US$750 million EDC performance-related support facility would be guaranteed by the Company and NNI during the term of the secured loan. As of January 30, 2006, there was approximately US$156 million of outstanding support utilized under the EDC Support Facility.

The loans under the facility would bear interest equal to LIBOR (or in certain cases a defined base rate) plus an applicable margin as set forth in the commitment letter. The loan documentation would contain representations, warranties, covenants and events of default customary for financings of this type, including a minimum Adjusted EBITDA covenant for the secured loan and a covenant applicable to both loans that unrestricted cash and cash equivalents of NNC on a consolidated basis must at all times exceed US$1.0 billion.

NNI would be required to prepay the facility in certain circumstances, including in the event of certain debt or equity offerings or asset dispositions of collateral by the Company, NNL or NNI. The financing commitments permit the lenders, in consultation with the Company, to further syndicate the facility and are subject to the completion of definitive documentation for the facility and other customary conditions. The Company and NNI have agreed to a demand right exercisable at any time after May 31, 2006 pursuant to which they would be required to take all reasonable actions to issue senior unsecured debt securities in the capital markets to repay the credit facility.

Cash

The Company’s consolidated cash balance at the end of 2005 was approximately US$3.0 billion.

Financial Reporting

The Company expects that the announcement and conference call related to its fourth quarter and full year 2005 results will coincide with the filing of the Company’s and NNL’s 2005 Annual Reports on Form 10-K with the requisite regulatory authorities.
