GENERAL TERMS AND CONDITIONS (Continued)

5.3 Temperature. The Gas to be made available to Transporter at the

Receipt Point(s) and made available to or on behalf of Shipper at the Delivery

Point(s) under this Tariff shall have a temperature of not more than one

hundred twenty (120) degrees Fahrenheit.

5.4 Failure to Conform to Specifications. If the Gas offered to be

made available to Transporter at the Receipt Point(s) or made available to or

on behalf of Shipper at the Delivery Point(s) shall fail at any time to

conform to any of the specifications set forth in Sections 5.1, 5.2, or 5.3,

then the party receiving such Gas (the "receiving party") shall notify the

other party (the "tendering party") of such deficiency and thereupon the

receiving party may at its option refuse to accept such Gas pending correction

by the tendering party. Upon the tendering party's failure promptly to remedy

any deficiency, the receiving party may accept such Gas and may make changes

necessary to bring such Gas into conformity with such specifications, and the

tendering party shall reimburse the receiving party for any reasonable expense

incurred by it in effecting such changes. In no event shall the failure of

any Gas offered for delivery to Transporter by Shipper or for Shipper's

account to conform to any of the specifications set forth in Sections 5.1, 5.2

or 5.3 relieve Shipper of Shipper's obligation to pay all applicable

reservation and/or usage charges. Further, Shipper shall reimburse Transporter

for all expenses incurred in repairing injuries to Transporter's facilities

resulting from Transporter's receipt of Gas for the account of Shipper which

does not conform to the specifications set forth in Sections 5.1, 5.2 and 5.3

and, notwithstanding the provisions of Sections 19 and 20, shall indemnify and

save harmless Transporter against any claims for damages arising from such

failure to conform to these specifications.
