GENERAL TERMS AND CONDITIONS

----------------------------

10.4 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 Trailblazer with a

nomination as required in accordance with Section 10.2 hereof.

10.5 CONFIRMATION BY TRAILBLAZER

(a) Nominations made in accordance with Sections 10.2,

10.3, 10.4, and 10.6 hereof shall not become effective until

Trailblazer has confirmed the nominated receipts and deliveries with

upstream and downstream parties, subject to Section 10.5(c). Shipper

shall designate the appropriate person(s) who has the authority to

resolve allocation issues, if requested by Trailblazer and, if

requested by Trailblazer, the appropriate person(s) to confirm

nominations. Confirmations must be submitted to Trailblazer through its

Interactive Website, or such other electronic means as are mutually

agreed upon by Trailblazer and Shipper.

(b) Subject to Section 10.2 and the other provisions

of this Tariff, Trailblazer shall provide Shippers and point operators

via its Interactive Website, or by EDI, the quantities that have been

scheduled to flow for that Shipper and point operator on the next day.

(i) With respect to the timely nomination/

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

the confirmation quantity or the previously scheduled quantity will be

the new confirmed quantity.

(ii) With respect to the processing of requests

for increases during the intra-day nomination/confirmation process, in
