4. REQUESTS FOR SERVICES (Continued)

4.14 Discounting (Continued)

In addition, the discount language of the 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 Transporter'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 provisions. However, nothing contained herein

shall be construed to alter a refund obligation under applicable

law for any period during which rates that had been charged under

a discount agreement exceeded rates which ultimately are found to

be just and reasonable.

4.15 Non-Conforming Negotiated Rates

(a) Authority and Conditions: The rate or rates to be charged for

Tariff may deviate in form or level from the

maximum-to-minimum ranges set forth on Statement of Rates of

this Tariff, provided:

(i) Transporter and Shipper have executed a valid service

agreement agreeing to such nonconforming negotiated

rate(s) or rate formula,

(ii) At the time of execution of such service agreement or

amendment agreeing to the nonconforming negotiated

rate(s) or rate formula, Shipper had access to service

pursuant to this Tariff at the rates then set forth on

the Statement of Rates, and

(iii) Prior to commencing service at such nonconforming

negotiated rate(s) or rate formula, Transporter will

have filed a tariff provision advising the Commission

of such agreement, stating the exact legal name of

Shipper and specifying the rate or rate formula

included in such agreement.
