7.4 On or before the nomination deadlines otherwise applicable

to Pipeline's service under the Subject Service Agreements,

Customer shall provide nomination data to Pipeline

consistent with the requirements of Section 11A of the

General Terms and Conditions, for each of Customer's

Eligible Points. Pipeline shall confirm that the

nomination data received from Customer is equivalent to

valid nominations under Subject Service Agreements that

will move gas away from the Eligible Points identified in

the Aggregation Agreement. The quantities determined

through this process shall be the "Scheduled Quantities."

7.5 After confirmation, any changes to TTT Quantities shall be

effective only if a corresponding nomination change has

been made under a Subject Service Agreement and this change

is confirmed by Pipeline. Confirmation changes received

pursuant to this Section 7.5 shall have prospective effect

only, and shall be confirmed by Pipeline.

7.6 If any nominated service from Pipeline under a Subject

Service Agreement fails to be scheduled for any reason,

e.g. because physical entities upstream or downstream of

Pipeline do not confirm such nomination, then Pipeline

shall inform Customer, and the parties shall revise

nomination data on a prospective basis, to reflect the

revised TTT Quantities. In order to address any mismatch

in quantities that cannot be resolved before Pipeline's

scheduling deadline, Customer shall provide Pipeline with

predetermined instructions at the time of nominations,

indicating which Subject Service Agreement(s) for Storage

or Balancing service are to be adjusted if sufficient gas

is not received or if excess quantities are tendered to

Pipeline. In the absence of instructions provided by

Customer, Pipeline will unilaterally determine the

allocation of such quantities to Subject Service

Agreements, to the extent that such agreements can be

identified by the information available to Pipeline on or

before its scheduling deadlines.
