10.2 Imbalance Resolution (continued)


(f) Imbalance Trades - The term "imbalance trade" shall mean the

reallocation of imbalances from one Shipper to another Shipper

in order to reduce the total amount of outstanding imbalances

of the parties. Transporter shall effect an election to trade

imbalances as posted and verified electronically. Imbalance

trades shall be based on a TSA's end-of-month imbalance.

imbalances if the trade does not serve to effectuate

transportation across persistent system capacity

constraints. Prior to the fifth Business Day following

monthly invoice date, Shipper must notify Transporter of

any trades to be applied to a prior Month's imbalances.

Subsequent to Transporter's issuance of invoices,

Shippers may post imbalances for trade for up to five

Business Days after monthly invoice date. At the

conclusion of the above five Business Days, Shipper's

imbalances shall be adjusted for the trades effectuated

pursuant to this Section 10.2(f)(i). Any remaining

imbalance quantities shall be subject to cash out,

pursuant to Section 10.3, in the second Month following

the Month in which the imbalance occurred.

will be applied in the following order:


1. to a Month 1 end-of-month imbalance;

described in Section 10.3(a)(iii);
