GENERAL TERMS AND CONDITIONS

13. IMBALANCES

13.1 RESPONSIBILITY FOR BALANCING

In addition to delivering and receiving volumes of gas

in conformance with nominations, Shippers are responsible for

conforming their takes at Delivery Points with their deliveries to

Natural at Receipt Points each day. Except for the no-notice aspect

of Rate Schedules DSS, FRSS, FTS-NB, FFTS-NB and FTS-G/NB, and

except as otherwise provided under an IBS Agreement, Natural has no

obligation to deliver for the account of a Shipper more volumes of

gas than Natural has received for the account of the Shipper or to

accept for the account of the Shipper more volumes of gas than are

being delivered for the account of the Shipper on any day.

13.2 MONTHLY IMBALANCES, NETTING AND OFFSETTING

At the end of each calendar month, to the extent the

net receipts (with the appropriate deductions for Fuel Gas and Gas

Lost and Unaccounted For and after giving appropriate recognition

to storage activity subject to applicable storage rights) do not

equal the deliveries under an Agreement on a Dth basis, and except

that any IBS Balance under an IBS Agreement is only subject to the

provisions of this Section 13 to the extent provided in Section

7(b) of Rate Schedule IBS, the following netting and offsetting

procedures will apply:

(a) Imbalances under a Shipper's different Agreements

will be netted together to obtain the Shipper's Total Monthly

Imbalance. The Total Monthly Imbalance will be shown with the

monthly billings sent to Shippers.

(b) To assist Shippers in arranging offsets, Natural

will post on its Interactive Website the Total Monthly Imbalance of

any Shipper which has notified Natural that it has elected to have

such information posted. Notification by the Shipper may be in

writing or on Natural's Interactive Website and shall be effective

by 8:00 a.m. on the next Business Day (Central Clock Time) if the

notification is received by 11:45 a.m. on a Business Day.

Imbalance information authorized for posting through such

notification shall be posted no later than the ninth Business Day

of the month after the imbalance occurred. Shippers shall have the

ability to post and trade imbalances, and imbalance information

shall remain posted, until the seventeenth Business Day of the

month after the imbalance occurred.
