GENERAL TERMS AND CONDITIONS

(continued)

D. With respect to the timely nomination/confirmation process at a receipt or

delivery point, in the absence of agreement to the contrary, the lesser of

the confirmation quantities should be the confirmed quantity. If there is

no response to a request for confirmation or an unsolicited Confirmation

Response, the lesser of the confirmation quantity or the previously

scheduled quantity should be the new confirmed quantity. Previously

scheduled quantity is intended to be the scheduled quantity previously

scheduled for the prior gas day during that gas day's timely nomination

period.

E. With respect to the processing of requests for increases during the

intraday nomination/confirmation process, in the absence of agreement

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

the new confirmed quantity. If there is no response to a Request For

Confirmation or an unsolicited confirmation response, the previously

scheduled quantity should be the new confirmed quantity.

F. With respect to the processing of requests for decreases during the

intraday 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.

G. The explicit confirmation process requires that the confirming party

respond to a Request for Confirmation or initiate an unsolicited

confirmation response. Absent mutual agreement to the contrary,

explicit confirmation is the default methodology.

H. Nominations received after the nomination deadline shall be processed

after the nominations received before the nomination deadline.

I. The receiver of a nomination initiates the confirmation process. The

party that would receive a request for confirmation or an unsolicited

confirmation response may waive the obligation of the sender to send.

J. At the end of each gas day, Transporter should provide the final scheduled

quantities for the just completed gas day. With respect to the

implementation of this process via the 1.4.5 and 1.4.6 scheduled quantity related

standards, Transporter should send an end of gas day scheduled quantity

document. Receivers of the end of gas day scheduled quantity document can

waive the sender's sending of the end of gas day scheduled quantity

document.

K. Transporter shall use Shipper-provided rankings when making

reductions during the scheduling process to the extent this

methodology does not conflict with Transporter's FERC Gas Tariff.
