14.6 Declared Entitlement Period. Transporter will notify Receiving

Party during the scheduling and confirmation procedure when an

interruption or curtailment is in effect due to capacity or supply

constraints which jeopardize system integrity. If deliveries to

that such interruption or curtailment is in effect, the unauthorized

overrun charge provisions as described in Section 15 of the General

Terms and Conditions will apply.

14.7 Records of Scheduled Quantities. Transporter shall keep

accurate records of the quantities of gas nominated and scheduled for

transportation, and any imbalances, which records shall be made

available to Receiving Party or Shipper upon request. If Receiving

Party's gas is commingled with other gas at the point of receipt or at

the point of delivery, the scheduling arrangements and Transporter's

records shall include procedures for the allocation of the total

quantity at such points. See Section 15 of the General Terms and

Conditions.

14.8 Arrangements Prior to Receipt and After Delivery. It shall be

Shipper's obligation to make arrangements with other parties for

delivery of gas into Transporter's system at the Receipt Point(s) and

for the receipt of gas after transportation at the Delivery Point(s).

Shipper shall be obligated in such arrangements to require dispatching

and operating coordination with Transporter and access to appropriate

charts and records. Such arrangements shall not be accepted by

Transporter unless found to be satisfactory by Transporter. Shipper

shall pay for any and all third party services including, but not

limited to compression, processing, gathering, transportation or

assigned nominating and balancing responsibilities or services.

14.9 Operating Information and Estimates. Upon request of

Transporter, Shipper shall from time to time submit its best estimates
