RATES

Except as otherwise provided below or in any written agreement(s) between the parties in effect during the term hereof, Shipper shall pay Natural the applicable maximum rate(s) and all other lawful charges as specified in Natural's applicable rate schedule. Shipper and Natural may agree that Shipper shall pay a rate other than the applicable maximum rate so long as such rate is between the applicable maximum and minimum rates specified for such service in the Tariff. Natural and Shipper may agree that a specific discounted rate will apply only to certain volumes under the agreement. The parties may agree that a specified discounted rate will apply only to specified volumes (MDQ, WQ, IQ or commodity volumes) under the agreement; that a specified discounted rate will apply only if specified volumes are achieved or only if the volumes do not exceed a specified level; that a specified discounted rate will apply only during specified periods of the year or for a specifically defined period; that a specified discounted rate will apply only to specified points, zones, mainline segments, supply areas, transportation paths, markets or other defined geographical area(s); that a specified discounted rate(s) will apply in a specified relationship to the volumes actually tendered (i.e., that the reservation charge will be adjusted in a specified relationship to volumes actually tendered); and/or that the discount will apply only to reserves dedicated by Shipper to Natural's system. Notwithstanding the foregoing, no discount agreement may provide that an agreed discount as to a certain volume level will be invalidated if the Shipper transports an incremental volume above that agreed level. In addition, the discount agreement may include a provision that if one rate component which was at or below the applicable maximum rate at the time the discount agreement was executed subsequently exceeds the applicable maximum rate due to a change in Natural's maximum rates so that such rate component must be adjusted downward to equal the new applicable maximum rate, then other rate components may be adjusted upward to achieve the agreed overall rate, so long as none of the resulting rate components exceed the maximum rate applicable to that rate component. Such changes to rate components shall be applied prospectively, commencing with the date a Commission order accepts revised tariff sheets. However, nothing contained herein shall be construed to alter a refund obligation under applicable law for any period during which rates which had been charged under a discount agreement exceeded rates which ultimately are found to be just and reasonable. If the parties agree upon a rate other than the applicable maximum rate, such written Agreement shall specify that the parties mutually agree either: (1) that the agreed rate is a discount rate; or (2) that the agreed rate is a Negotiated Rate (or Negotiated Rate Formula). In the event that the parties agree upon a Negotiated Rate or Negotiated Rate Formula, this Agreement shall be subject to Section 49 of the General Terms and Conditions of Natural's Tariff.

DELIVERY PRESSURE, ASSUMED ATMOSPHERIC PRESSURE

Natural gas to be delivered by Natural to Shipper, or for Shipper's account, at the Delivery Point/s shall be at the pressure available in Natural's pipeline facilities from time to time. The measuring party shall use or cause to be used an assumed atmospheric pressure corresponding to the elevation at such Delivery Point/s.
