TRANSPORTATION SERVICE AGREEMENT

(continued)

(d) Rate-Related Provisions:

(i) Consideration for Rate Granted: Transporter agrees to the rates specified herein or on

Attachment A in exchange for Shipper's agreement to forego credits or other benefits to

which Shipper would otherwise be entitled, but only to the extent such credits or

benefits would result in a greater economic benefit over the applicable term than that

represented by the agreed-upon rate. Accordingly, unless Transporter otherwise agrees,

Shipper will not receive credits (with the exception of (1) penalty revenue credits

provided pursuant to Section 31 of the General Terms and Conditions of Transporter's

Tariff, and (2) capacity release credits) from rates, refunds or other revenues collected

by Transporter or Shipper if to do so would effectively result in a lower rate or greater

economic benefit to Shipper; provided, however, that [for a Shipper taking service under

a discount or recourse rate agreement, the rate in any month shall never be above

Transporter's applicable maximum Tariff rate] [for a Shipper taking service under a

Negotiated Rate agreement, Transporter and Shipper can agree pursuant to Section 19.8 of

the General Terms and Conditions of Transporter's Tariff that Transporter will retain

some or all of the capacity release credits to the extent those credits exceed the amount

of the Shipper's invoiced demand component.] If the parties' agreement to the

foregoing is determined
