10. TRANSPORTATION BALANCING (Continued)

(iii) MRT shall "cash out" a Customer's current month's

imbalance(s) at any time after the end of that month by paying or

crediting (which shall be at MRT's option) to the Customer or by

receiving from the Customer the dollar value of the imbalance.

After no notice storage adjustments and gas trading have occurred,

any remaining excess receipts in a zone will be transported (and

charged applicable transportation charges and fuel charges and/or

allowances) to any zone with excess deliveries in order to reduce

the imbalances in each zone prior to cashing out the imbalance.

(iv) Imbalances attributable to complying with Operational

Flow Orders will be valued at the average weekly price used to

determine the Index Buy or Index Sell Prices, as applicable, for

the week in which such imbalances occurred.

(v) In determining the over-received and over-delivered

quantities for the month, MRT will utilize the data provided

pursuant to Section 10.3(a) above.

(vi) Prior to the date of the cash out, each Customer may

reduce its imbalance through the Gas Trading Program provisions

set forth in Section 10.4 hereof.
