GENERAL TERMS AND CONDITIONS

(Continued)

1. DEFINITIONS (Continued)

1.19 "Electronic Delivery Mechanism" or "EDM" shall mean the electronic

communication methodology used to transmit and receive data related

to Gas transactions. Transporter shall designate an electronic

"site" at which Shippers and Transporter may exchange data

electronically. All data provided at such site shall be considered

as being delivered to the appropriate party.

Transporter's use and implementation of EDM shall conform to all

appropriate GISB Standards.

Furthermore, Transporter's implementation of EDM shall be specified

in an Electronic Data Interchange Trading Partner Agreement, which

shall substantially conform to the GISB Model EDI Trading Partner

Agreement.

1.20 "Electronic Transmission" or "Electronic Communication" shall mean

the transmission of information via Transporter's electronic

bulletin board, Transporter's standardized Internet Web Site ("Web

Site"), Electronic Data Interchange (EDI), including information

exchanged via EDM. These terms exclude facsimile.

1.21 "End Date" shall mean the Day specified by a Shipper on which a Gas

transaction is to end. Most Gas transactions are to be effective for

a full Gas Day. However, Shipper may indicate a requested end time

when submitting Intraday Nominations.

1.22 "Equivalent Quantities" shall mean the sum of the quantities of Gas

measured in Dth received by Transporter for the account of Shipper

at the Points of Receipt during any given period of time reduced by

the FL&U Adjustment and any Gas vented as provided in Section 3.3

hereof during the same period of time.

In determining Equivalent Quantities for Delivery, each Shipper

shall provide the FL&U Adjustment based on the actual quantity of

Gas Tendered by such Shipper to Transporter; provided, however, that

each Shipper shall be responsible for Unauthorized Overrun Gas

Tendered by it to Transporter which is vented under Section 3.3;

provided further, that the FL&U Adjustment shall be modified

periodically to reflect Transporter's actual operating experience as

described in Section 1.27 ("FL&U Requirement"). Each Shipper's share

of Transporter's total FL&U Requirement shall be calculated as a

percentage of each Shipper's Gas at each Point of Receipt.
