Subject: "CERS Update".

Body: Market Notice October 29, 2001 Market Participants: The ISO has been notified that effective HE0800 (beginning at 0700) October 30, 2001, CERS will no longer provide creditworthy backing of negative decremental energy bids and negative OOM sales (i.e. any bids below zero dollars). If for reliability purposes, the ISO needs a negative decremental energy bid, CERS has indicated to the ISO that it may back such bids on a case-by-case basis at its sole discretion. Accordingly, in continuing compliance with FERC's orders, the ISO will not dispatch any negative decremental energy bids or any negative OOM sales absent assurances of creditworthy backing. Please contact your Client Representative with any questions.

Subject: "Average Tenure and Deal Count Information".

Body:
Hi Sally, Attached is the first cut at average deal count and tenure information for EOL and non-EOL trading. The only missing pieces at this point are European Metals and "Other", both of which we should have from London first thing in the morning. I will send an updated file as soon as we have that information, and we wil be standing by tomorrow in case there are any revisions needed, or additional requests. Thanks,
