18.1 (c) (iii) In the absence of an executed OBA in effect or a valid election by the

receipt point operator pursuant to 18.1(c)(ii) above, Seller will

allocate the measured quantity pro-rata based on the scheduled quantity

for each transaction. Further, in the absence of an executed OBA in

effect, quantities will be allocated to scheduled displacement

transactions prior to scheduled non-displacement transactions.

Prior period adjustments to scheduled quantities and PDAs shall be

permitted by Seller only if all parties affected by the resulting prior

period reallocation (including Seller) consent in writing to the

adjustment; provided, however, Seller shall not unreasonably withhold

such consent.

Make-up quantities, including imbalance quantities that are being resolved in-

kind, shall be deemed to be the "last through the meter." Imbalance quantities

returned in-kind in the current month are applied first to the previous month

imbalance until such balance is zero and then applied to the current month

imbalance.
