(c) Nominations received after the timely nomination

deadline will be scheduled after the nominations received by that

deadline.

7.4 REQUIRED NOMINATION CHANGES

If estimated daily flows under a particular

transportation Agreement differ from the confirmed nominations, or if

an imbalance has occurred due to some other reason, then prospective

nomination change(s) (either receipt or delivery adjustments) may be

required to bring the receipt and delivery volumes into balance. When

a Shipper receives notification of a required change in the

nomination, the Shipper shall be responsible for informing upstream

and downstream parties of the prospective change and providing Horizon

with a nomination as required in accordance with Section 7.2 hereof.

7.5 CONFIRMATION BY HORIZON

(a) Nominations made in accordance with Sections 7.2,

7.3, 7.4, and 7.6 hereof shall not become effective until Horizon has

confirmed the nominated receipts and deliveries with upstream and

downstream parties, subject to Section 7.5(c). Shipper shall designate

the appropriate person(s) who has the authority to resolve allocation

issues, if requested by Horizon and, if requested by Horizon, the

appropriate person(s) to confirm nominations. Confirmations must be

submitted to Horizon through DART, or such other electronic means as

are mutually agreed upon by Horizon and Shipper.

(b) Subject to Section 7.2 and the other provisions

of this Tariff, Horizon shall provide Shippers and point operators via

DART, or by EDI, the quantities that have been scheduled to flow for

that Shipper and point operator on the next day.

(c) Default confirmation procedures are as follows:

(i) With respect to the timely nomination/

confirmation process at a receipt or delivery point, in the absence of

agreement to the contrary, the lesser of the confirmation quantities

will be the confirmed quantity. If there is no response to a Request

For Confirmation or an unsolicited Confirmation Response, the lesser

of the confirmation quantity or the previously scheduled quantity will

be the new confirmed quantity.
