AGGREGATION SERVICE (Cont'd)

(ii) Two days before each of the flow dates set forth on the following schedule, Shipper

shall confirm with Transporter through Transporter's EBB the sale and nomination for transportation of

the minimum percentages of the estimated Appalachian production set forth below:

Flow Date Percentage of Gas Sold

1st 25% (of quantity)

8th 50%

15th 75%

22nd 100%

(iii) If the requisite percentages of gas from Appalachian receipt points are not sold and

nominated for transportation by the flow dates specified, Transporter may (i) issue interruption or

operational flow orders to Shipper, and (ii) reduce supplies in accordance with Shipper's supply

reduction lists, as specified in Section 4(a)(ii) of this Rate Schedule.

(iv) At any receipt point or delivery point where gas is flowing to or from multiple

parties, Shipper shall provide to Transporter a Predetermined Allocation Methodology agreement in

accordance with the procedures set forth in Section 8 (Meter Allocations) of the General Terms and

Conditions.

(v) Shipper shall provide to Transporter through Transporter's EBB, at such times as may

be established by Transporter, the following information: the names of the shippers nominating gas

from Shipper's Aggregation Point; the transportation contracts held by those shippers, identified by

Transporters' contract number; the quantities nominated by each shipper; a supply reduction list for

such quantities; and such other data as Transporter may deem necessary to render service.

Transfers among Aggregation Points or to Service Agreements under Transporter's IPP Rate Schedule also may be

permitted on an interruptible basis. Requests for such transfers shall be made in accordance with the

nomination procedures set forth in Section 6 (Nominating, Scheduling, and Monitoring) of the General Terms and

Conditions. Transporter shall not unreasonably withhold approval of pool-to-pool transfers.

(d) In the event that supplies exceed nominations for a given pool under this Rate Schedule,

Shipper shall identify through Transporter's EBB the priorities of flow so as to enable Transporter to reduce

supplies to match the market demand. In the event that nominations exceed supplies for a given pool under

this Rate Schedule, Transporter shall reject any nominations against that pool that have not been confirmed by

Shipper.

(e) Any differences between confirmed nominations and actual receipt quantities shall be held as an

operational imbalance under Shipper's AS Service Agreement. Such an imbalance shall not exceed two percent of

Shipper's aggregate nominations for the Month. To maintain a concurrent balance between receipts and

deliveries, Transporter may monitor and adjust confirmed nominations in accordance with the provisions of

Section 6 (Nominating, Scheduling, and Monitoring) of the General Terms and Conditions. Shipper shall correct

operational imbalances at the first available opportunity, but in no event later than the last day of the

month in which Shipper is notified of its imbalance status for the immediately preceding month, by tendering a

nomination to Transporter in accordance with Sections 6.2(j) and 6.2(k) of the General Terms and Conditions.
