Question and Answers

1. Feedback of sales force is the element of voice quality on voice. Feels there is price stabilization in voice and data pricing. Quality is becoming increasingly important, especially in enterprise sector. Large enterprise certainly has large pricing pressure. Challenge now is growing business within large enterprise existing customers. Greatest activity has been on data side of business.

2. Cash portion of restructuring will be between $10 to $15m in total over next few quarters.

3. There is a seasonality to business. There could be a lull in minutes per day during the November and December holidays. Perhaps a slight downtick in revenues in 4Q03.

Some “ back of the envelope” observations

Based on the lack of comparative information, including the forthcoming 10-Q and 8K, and the lack of guidance , we will hold off on making financial observations at this time. There are a few items we will identify below.

1. Conference call had no mention of Gig-Be (other than some slight Government mention) or Dorsal.
