8.	FURTHER AGREEMENT:

A.	The rate for the Primary Route No Notice Entitlement as listed in the attached Primary Route Exhibit shall be a Monthly Reservation Rate of $3.7500 per dth and the applicable Commodity Rate of $0.0150 not to exceed Transporter's Maximum Tariff Reservation and Commodity Rate.

B.	In addition, if one rate component which was at or below the applicable Maximum Rate at the time this 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, as long as none of the resulting rate components exceeds 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 sheet rates. 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.

C.	Shipper shall be entitled to the Right of First Refusal provided for in Section 22 of the General Terms and Conditions of Transporter's FERC Gas Tariff, notwithstanding the fact that Shipper would otherwise be ineligible for this right under Section 22.2.
