behalf of Shipper at the Delivery Point(s) has failed at any time to conform

to any of the specifications set forth in Section 1 or 2 of this Article IV,

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 in quality as specified in Section 1 or 2 of this Article IV,

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 Section 1 or 2 of this

Article IV relieve Shipper of Shipper's obligation to pay Monthly Demand

Charges, if applicable. In no event shall the failure of any gas made

available to or on behalf of Shipper at any Delivery Point(s) to conform to

any of the specifications set forth in Section 1 or 2 of this Article IV

relieve Shipper of Shipper's obligation to pay the Unit Commodity Rates and,

if applicable, Monthly Demand Charges.

received
