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 Shippers 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(s) 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.
