DISCOUNT TERMS AND CONDITIONS; APPLICABLE CHARGES

2.1 General Discount Limitations: The Discounted Daily Access Rate shall apply only to an aggregate

maximum daily access quantity equal to the Discounted Daily Access Quantity set forth in Section

1.3 above, based upon the absolute values of confirmed daily Access Requests (i.e., swing up Access

Requests will not be netted against swing down Access Requests) at the Discounted Delivery Points;

provided, however, that to the extent that the IBS Agreement MDQ is permanently or temporarily

reduced under the provisions of Natural's FERC Gas Tariff, then effective as of the date of any

such reduction, the Discounted Daily Access Quantity shall be reduced pro rata based on the ratio

of the Discounted Daily Access Quantity to the IBS Agreement MDQ, as such ratio existed immediately

prior to the IBS Agreement MDQ reduction. Any balancing service provided on any day in excess of

the Discounted Daily Access Quantity shall be billed at all applicable maximum rates, charges, and

surcharges set forth in Natural's FERC Gas Tariff, as may be revised from time to time. The

Discounted Daily Access Quantity shall only apply to balancing service provided in connection with

transportation service provided by Natural to Shipper to the Designated End Use Facility under the

Linked Transportation Agreement.

2.2 Applicable Rates, Charges, and Surcharges: Unless otherwise expressly provided in this Agreement

all applicable maximum rates, charges, surcharges, and penalties of any nature set forth in

Natural's FERC Gas Tariff, as may be revised from time to time, shall apply to service provided to

Shipper under the IBS Agreement, including without limitation all applicable authorized overrun

charges, unauthorized overrun charges, and balancing service charges.
