RESERVATION CHARGE CREDITS (Contd.)

7.1 GENERAL (Contd.)

B. For non-Intra-Day Nominations, a rollover option is

available such that a Shipper shall have the ability to

nominate for several Days, Months, or Years, provided the

Nomination begin and end dates are within the term of the

Shipper's contract. All Nominations should be based on a

daily quantity and all volumes shall be expressed in Dth per

Day and shall be stated for each Receipt and Delivery Point.

C. If an upstream or downstream party requires additional

information, if the volumes transported are subject to a

discounted rate, or if additional information is otherwise

required by Transporter, then, upon notification by

Transporter, Shipper must include in each Nomination such

additional information as is specified by Transporter.

Nominations must be submitted to Transporter through

Transporter's Interactive Website, or through such other

electronic means as are mutually agreed upon by Transporter

and Shipper. The sending party should adhere to Nomination,

confirmation and scheduling deadlines. The receiving party

may waive any submittal deadline in this Section 7.

D. The standard quantity for Nominations, confirmation and

scheduling is dekatherms per Gas Day in the United States,

gigajoules per Gas Day in Canada and gigacalories per Gas

Day in Mexico. (For reference, 1 dekatherm = 1,000,000

Btus; 1 gigajoule = 1,000,000,000 joules; and 1 gigacalorie

= 1,000,000,000 calories.) For commercial purposes, the

standard conversion factor between dekatherms and gigajoules

is 1.055056 gigajoules per dekatherm and between dekatherms

and gigacalories is 0.251996 gigacalories per dekatherm.

The standard Btu is the International Btu, which is also

called the Btu (IT); the standard joule is the joule

specified in the SI system of units. The International Btu

is specified for use in the Gas measurement standards of the

American Gas Association, the American Petroleum Institute,

the Gas Processors Association and the American Society for

Testing Materials. For non-commercial purposes, these

associations note that the exact conversion factor is

1.05505585262 Gigajoules per Dekatherm.
