GENERAL TERMS AND CONDITIONS

(CONTINUED)

8. IMBALANCE RESOLUTION PROCEDURES (continued)

8.4 Trading: Posting and trading of the previous Month's netted

Transportation Imbalances will be allowed within each Operational

Impact Area between imbalance agents (or the Cashout Party, if no

imbalance agent exists) from the first calendar Day of the

current Month until the end of the 17th Business Day of the

current Month. Imbalances to be posted for trading should be

authorized by the Cashout Party. Authorizations to post

imbalances that are received by Transporter by 11:45 A.M. should

be effective by 8:00 A.M. the next Business Day (Central Clock

Time). Imbalances previously authorized for posting should be

posted on or before the ninth Business Day of the Month.

Transporter should provide the ability to view and, upon request,

download posted imbalances. Transporter should not be required

to post zero imbalances. When trading imbalances, a quantity

should be specified. Trading will be allowed only when (i)

imbalances are within the same Operational Impact Area and (ii)

the resulting trade will reduce the imbalances for each Cashout

Party or its imbalance agent. Transporter shall allow Cashout

Parties to trade imbalances with other Cashout Parties within the

same Operational Impact Area if the two Cashout Parties'

imbalances are offsetting balances such that the net imbalance

for each Cashout Party after the completion of the trade would be

reduced to a quantity closer to zero. A Cashout Party may trade

any imbalance with another Cashout Party, provided that the trade

shall not result in a Transportation Path which crosses a Posted

Point of Restriction; provided further that to the extent the

imbalances were incurred during the remainder of the Month when

no Posted Point of Restriction was in effect, those imbalances

are available for trading. Transporter should enable the

imbalance trading process by receiving the request for imbalance

trade, receiving the imbalance trade confirmation, sending the

imbalance trade notification, and reflecting the trade prior to

or on the next monthly Shipper Imbalance Statement or Cashout

statement. After receipt of an imbalance trade confirmation,

Transporter should send the imbalance trade notification to the

initiating trader and the confirming trader no later than noon

(Central Clock Time) the next Business Day. Imbalance trades can

only be withdrawn by the initiating trader and only prior to the

confirming trader's confirmation of the trade. Imbalance trades

are considered final when confirmed by the confirming trader and

effectuated by Transporter.
