GENERAL TERMS AND CONDITIONS (Continued)

(iii) With respect to the processing of requests for decreases during

the Intra-day Nomination/confirmation process, in the absence of agreement to

the contrary, the lesser of the confirmation quantities should be the new

confirmed quantity, but in any event no less than the elapsed-prorated-

scheduled quantity. If there is no response to a request for confirmation or

an unsolicited confirmation response, the greater of the confirmation quantity

or the elapsed-prorated-scheduled quantity should be the new confirmed

quantity.

(iv) With respect to Section 7.12, if there is no response to a

request for confirmation of an unsolicited confirmation response, the

Transporter shall provide the Shipper with the following information to

explain why the Nomination failed, as applicable:

(1) the Transporter did not conduct the confirmation;

(2) the Shipper is told by Transporter that the upstream confirming

party did not conduct the confirmation;

(3) the Shipper is told by Transporter that the upstream service

requester did not have the gas or submit the Nomination;

(4) the Shipper is told by Transporter that the downstream confirming

party did not conduct the confirmation;

(5) the Shipper is told by Transporter that the downstream service

requester did not have the market or submit the Nomination. This information

should be imparted to the Shipper on the Scheduled Quantity document.

Elapsed-prorated-scheduled quantity means that portion of the

Scheduled Quantity that would have theoretically flowed up to the effective

time of the Intra-day Nomination being confirmed, based upon a cumulative

uniform hourly quantity for each Nomination period affected.
