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

additional information, if the volumes transported are subject to a

discounted rate, or if additional information is otherwise required by

Natural, then, upon notification by Natural, Shipper must include in each

nomination such additional information as is specified by Natural.

Nominations must be submitted to Natural through Natural's Interactive

Website, or such other electronic means as are mutually agreed upon by

Natural and Shipper. The sending party should adhere to nomination,

confirmation, and scheduling deadlines. The receiving party may waive any

submittal deadline in this Section 8.

(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.
