PRESENTATION SUMMARY

S1. 1Q06 Review (M.Z.) 1. Highlights: 1. NT is current in its financial reporting and plans to remain as such. 2. Revenues came in pretty much in line, but GM was lower than the Co. had expected. 3. Revenue and operating margin momentum for the Co.'s business commencing in 2Q06 is pretty much in line with its previously communicated full-year game plan. 4. The rest of the year growth is expected to be very broad-based, but particularly strong is CDMA and optical from a product line perspective and from region in Europe and in CALA. 5. The Co. is driving both improvements in short-term financial results and at the same time making investments for the long-term health of the Co. 2. Revenues: 1. 1Q06 revenues of $2.4b were relatively flat on a YoverY basis, which was pretty much in line with the Co.'s expectations. 2. Revenues were impacted by the timing of certain contracts and both the backlog and deferred revenues increased during 1Q06. 3. The incremental impact of the NT-LG JV and the PEC acquisition, which is now part of the Nortel Government

The Co. was negative both on an operating and margin basis. 1. 6.9% operating margin percentage. 2. Net loss for 1Q06 was $160m (sic - see press release) vs. $104m in 1Q05. 1. The primary shortfall impacting results was the GM. 2. The Co. was not happy with the net loss for 1Q06, and it reiterated its commitment on implementing the programs,

which will deliver the 300-500 BP improvement per year and ultimately double-digit operating margin by 2008. 3. The Co. expects growth for the remainder of 2006 and for this to be very broad-based both product line wise and region wise on a YoverY basis. 4. Revenues by Segment: 1. Mobility and Converged Core: 1. Revenues were down 4% over 4Q05. 2. CDMA was down 4% primarily due to timing. 3. The Co. expects very strong CDMA revenues for the year. 1.

remains a strong No. 2 position globally. 4. NT also continues to invest behind EV-DO with MIMO and OFDM, which will be the foundation of future mobile access networks. 5. On the GSM and UMTS front, revenues were down 11%, principally down with GSM revenues down, including in North America. 1. This was partially offset by growth in UMTS. 2.

Going forward, the Co. anticipates significant buildout in GSM in the emerging markets, including increased activity in China as the 3G licenses are delayed. 8.
