Rate Schedule SA (continued)

Supply Aggregation Service

3.4 At the time of nomination, Aggregator may provide to Transporter a

predetermined ranking of both receipts and deliveries. In the event of an

interruption or reduction in the supplies or markets, or in the event that

pipeline operating conditions require Transporter to adjust scheduled

receipts or deliveries as described in Section 3.3 above, Transporter may

restrict scheduled quantities based on the Aggregator's pre-determined

ranking provided pursuant to this Section 3.4.

3.5 Quantities nominated from receipt points to supply aggregation service

agreements shall have the same scheduling priority as the take-away

transportation service agreement(s) from the pooling area(s).

4. IMBALANCE RESOLUTION

4.1 Transporter will provide notice to Aggregator of any imbalance situation

needing resolution and will specify the necessary corrective action.

Aggregator shall take corrective action as specified by Transporter, or

provide Transporter an alternate schedule for correcting imbalance. In the

event that Transporter determines, in its sole discretion, that the

Aggregator has not made a good faith effort to correct the imbalance,

Transporter has the right, with twenty-four hours prior notice to

Aggregator, to reduce receipts into, or deliveries out of, Aggregator's

supply aggregation service agreement, based on the pre-determined rankings

provided pursuant to Section 3.4 of this Rate Schedule.

4.2 Any imbalances between allocated receipts and allocated deliveries

("allocated imbalance") or any scheduled imbalances pursuant to Section 3 of

this Rate Schedule which are not made up before the end of the month shall

be the responsibility of Aggregator and shall be resolved pursuant to the

cash out provisions of Rate Schedules LMS-MA and LMS-PA. Imbalances under

this Rate Schedule SA shall be computed and cashed out separately for each

pooling area.
