3.5 Adjustment of Rates: Subject to the terms of the Service

Agreement, Transporter may prescribe and/or adjust at any time any of

the rates applicable to any individual Shipper without adjusting any

other rates for that or another Shipper; provided, however, that such

adjusted rate(s) shall not exceed the applicable maximum rate(s) nor

shall they be less than the applicable minimum rate(s), set forth on

Sheet No. 16 of this Tariff or any superseding tariff. Such minimum and

maximum rates shall not be applicable to service provided pursuant to

Section 51 of the General Terms and Conditions of this Tariff. Should

the General Terms and Conditions, Transporter and Shipper shall "cash

out" any imbalance between receipts and deliveries under each

transportation Service Agreement. The applicable cash-out amount shall

be determined by multiplying the monthly imbalance by the appropriate

index price multiplier as defined in Subsection 15.5 and the applicable

index price as defined in Subsection 15.5.1 of the General Terms and

Conditions. Nothing herein shall limit Transporter's right to take such

actions of whatever nature that may be required to correct imbalances

which threaten the integrity of its system.
