GENERAL TERMS AND CONDITIONS (Continued)

(d) If such revised Nomination for any Receipt or Delivery Point

is not provided within the time required in Section 7.5(c) above, or if it

exceeds the available capacity for any Receipt or Delivery point, then the

Scheduled Quantity for such Receipt or Delivery Point shall be deemed to be

the quantity of Gas reported in Transporter's response in accordance with

Section 7.5(b) above.

7.6 Late Nominations, Modifications of Scheduled Quantities and

Nominations by Replacement Shippers. Requests for modifications of previously

scheduled service, and Nominations by Replacement Shippers which have just

acquired capacity pursuant to the General Terms and Conditions, will be

accommodated where such requested Nomination or modification does not

interfere with operation of the System or Transporter's ability to render

other scheduled service. In the event capacity remains available on the

System after service has been nominated and scheduled in accordance with

Sections 7.1 through 7.5 above, or capacity becomes available either due to

requests from Shippers which have previously scheduled service to change such

scheduled service, or due to operational or weather situations which permit

Transporter to render additional service without compromising service already

scheduled, Transporter will accept late Nominations for service and shall

endeavor, but shall not be obligated, to provide service which implements such

late Nominations.

7.7 Minimum Quantity Meterable. In no event shall Transporter be

required to schedule for service a quantity of Gas which Transporter cannot

meter with reasonable accuracy at the Receipt or Delivery Points for which

Shipper is requesting service. If Shipper nominates a quantity of Gas which

Transporter cannot meter with reasonable accuracy at the requested Receipt

and/or Delivery Point(s), Transporter will promptly so inform Shipper and

advise Shipper of the minimum quantity that can be metered with reasonable

accuracy at the proposed Receipt and/or Delivery Point(s).

7.8 Coordination with Other Parties. Shipper shall make all necessary

arrangements with other parties at or upstream of the Receipt Point(s) where

Gas is delivered to Transporter by Shipper or for Shipper's account and

downstream of the Delivery Point(s) where Gas is made available to Shipper,

which arrangements shall be compatible with the System operations and

coordinated with Transporter's dispatchers.
