Subject: "November & December 1999 Settlement Adjustments".

Body: market_relations@nyiso.com writes to the NYISO_TECH_EXCHANGE Discussion List: Dear Market Participants: On the November 1999 & December 1999 Transmission Customer Monthly Statements many customers have noted under the "Energy Settlement" section for "Forward Energy" a change in MW-Hrs with no associated change in dollar amounts. This is because of a correction in the sign convention for the MW-Hrs related to external generation transactions (transactions from a proxy bus to the NYISO reference bus). For all other types of transactions the NYISO charges customers the appropriate TUC or LBMP based on the MWs that flowed, but for external generation transactions, customers receive payments from the NYISO, and therefore these types of transactions have an opposite sign convention. The dollars associated with the external generation transactions have always had the proper sign convention, but the MW-Hrs have not. On 01/17/2000 this sign convention was corrected for all billing months going forward resulting in the correct MW-Hr values being reported from February 2000 to date. However, November 1999 - January 2000 did not have the proper MW-Hrs reported on the Transmission Customer Monthly Statements. With the latest settlement adjustments posted the MW-Hrs are being corrected with the proper sign convention. Transmission Customers will see similar changes in their forward energy MW-Hrs for January 2000's settlement adjustment.

Subject: "Investing advice".

Body: Mr. Lay, I am a current holder of Enron common stock. I would like your opinion. I am 61 years old. My first stock purchase was of my Enron stock earlier this year. ($38.65) I am not in the market for the short term. I am not spending money that will affect my standard of living. I am considering buying a couple of hundred shares of Enron stock. Do you think this purchase would be an investment that will grow in the long term or would it be a donation to Enron's creditors. Thank You.

Subject: "flexible deal view data archiving".

Body: Jeff, I spoke with Jay briefly about the potential of archiving all physical deals every night into a separate database instead of deleting them. We currently are capturing that information in our database, but the feed Jay has is more extensive and reliable. We'd then be able to build some historical queries and facilitate some of the requests we have for this data, I don't anticipate it would take much time to do this. You have any objections? Thanks,

Subject: "Duke Situation".

Body:
Greg, ACTION - PLEASE CALL TODD REID AT DUKE BACKGROUND: Below is the situation with Duke and subs: Exposure Line Cash L/C Duke Energy Marketing LP / ECC ($43mm) $10mm $52.35mm $20.5mm Duke Energy Trading & Marketing / ENA ($56mm) $5mm $61mm Duke Energy Trading & Marketing / EPMI ($260mm) $20mm $171mm $100mm The expiration of the letters of credit are 11/30/01. Duke believes that since these L/C's have less than 20 days to expiry their value should be zero and are asking for additional cash collateral. Our view of the contract is that these L/C's are good collateral until expiry and should be counted in our outgoing collateral. The roll of the letter of credit has been delayed as Haedicke/Mintz get comfortable with the reps under the L/C facility. Duke credit guys are saying that Todd Reid has not received a return call from you and this holding up a resolution. Bill and Louise
