13.11 Prior Month Adjustments

If a Prior Month Adjustment (PMA) is to be made (either at the request

of Shipper or at Transporter's initiative), Transporter will notify

Shipper on or before the ninth (9th) of the month following the close

of each month of the amount and nature of the PMA, either as part of

the Monthly Imbalance Statement or in a separate communication.

Shipper has until the end of the month following the month in which

such notification was made to resolve the PMA in kind by adjusting

Shipper's receipts and deliveries of gas.

If the PMA is not resolved in kind within the required time, a

positive PMA (Shipper has too much gas on Transporter's system) will

be resolved by Transporter's retaining an amount of Shipper's gas

equal to the amount of the PMA, at no cost and free and clear of all

claims by any party.

A negative PMA (Shipper has insufficient gas on Transporter's

system) will be resolved by Shipper's paying to Transporter an amount

of money equal to the amount of the PMA (expressed in dekatherms)

multiplied by the Cash-Out Price applicable to the month which was

adjusted by that PMA. Shipper's regular bill for transportation

services will include the amount of gas retained by Transporter

pursuant to this paragraph and/or the amount which is owed by Shipper

pursuant to this paragraph, which will be subject to all payment and

collection requirements applicable to that bill.
