GENERAL TERMS AND CONDITIONS

(Continued)

10. NOMINATIONS, BALANCING AND CHARGES FOR IMBALANCES OR UNAUTHORIZED

TENDERS OR TAKES (Continued)

(e) Procedural Changes. Transporter shall provide Shippers

with thirty (30) days prior written notice of nomination and

nomination verification deadline changes unless a lesser period of

time is required to protect the integrity of Transporter's system.

10.2 Balancing: Shipper shall use its best efforts to avoid

delivering or receiving quantities of gas which differ or deviate from

the quantity of gas scheduled by Transporter for transportation and

delivery hereunder and shall keep Transporter advised of any material

deviations from the quantities scheduled. Shipper shall be responsible

for monitoring, controlling and, if necessary, adjusting its deliveries

of gas at the Receipt Point(s) and its receipts of gas at the Delivery

Point(s) in order to maintain a daily balance between the quantity of

gas received by Transporter from Shipper or its designee, less any gas

retained for fuel use and loss by Transporter in providing such service,

and the quantity of gas delivered by Transporter to Shipper or its

designee. Transporter shall not be obligated to deliver to Shipper at

the Delivery Point(s) quantities in excess of the quantities received

for Shipper at the Receipt Point(s), after deductions for fuel use and

loss, nor shall Transporter be obligated to receive at the Receipt

Point(s) for Shipper's account quantities of gas in excess of the

quantities delivered to Shipper at the Delivery Point(s), after

deductions for fuel use and loss.

10.3 Charges for Imbalances: If Shipper fails to maintain a

balance of receipts and deliveries and such failure is not the result of

force majeure as specified in Section 9 of the Transportation General

Terms and Conditions or of Transporter's sole negligence or willful act

causing such an imbalance, Transporter may impose one or more of the

following imbalance charges. No imbalance charge shall be assessed

until Transporter has notified Shipper in writing that an imbalance

exists and Shipper has failed to take corrective action acceptable to

Transporter. In calculating excess and deficient quantities,

Transporter shall take into consideration quantities retained for fuel

use and loss and adjustments for any prior imbalance pursuant to

Transporter's notification to correct any excess or deficiency in

receipt and deliveries.
