confirming the nomination for scheduling and allocation.

Shipper must provide electronically to GTN Shipper's

current designated contact, after hours and emergency

telephone numbers. Such information must be updated as

often as changes to such information occurs. GTN may rely

solely upon the information provided by Shipper and will

not be liable to Shipper if Shipper's contact information

is outdated and communication attempts with such Shipper

are unsuccessful.

19.4(e) Uniform Hourly Rates

Scheduled quantities will be received and delivered at a

uniform hourly rate of confirmed quantity divided by 24,

unless as determined by GTN, variance from the hourly rate

will not be detrimental to the operation of the pipeline or

adversely affect other GTN Shippers.

Nominations for service on GTN shall be further governed by

the following standards adopted by the North American

Energy Standards Board. Unless otherwise specified, all

agency agreements on third-party pipelines that will allow

GTN to place transportation service nominations for Shipper

on both GTN and other third-party pipelines. A nomination

of service fee shall be negotiated between GTN and Shipper

for such service. GTN will provide this service on a non-

discriminatory basis.
