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

26.2 TOXIC HAZARDOUS SUBSTANCES

Shipper agrees to supply or cause its designee to

supply to Natural upon demand, at any time and from time to time,

a sample of liquids removed from the gas stream at any Receipt

Point, whether removed by a coalescer or otherwise, for analysis

at a laboratory of Natural's choosing. If at any time PCBs or any

other toxic substances or chemicals that Natural deems hazardous

and/or in any way unsafe for transportation are found in the

liquid samples supplied to Natural by Shipper, Natural may in its

sole discretion immediately cease the receipt of such gas and any

associated liquids through its facilities. Upon proof that such

toxic or hazardous substances are no longer present at levels

deemed unsafe by Natural, Natural shall restore service to Shipper

at the affected Receipt Point.

26.3 NON-CONFORMING GAS

(a) If at any time, gas tendered under an Agreement

shall fail to conform to any of the quality specifications set

forth above the receiving party may, at its option exercised on a

non-discriminatory basis, refuse to accept delivery pending

correction of the deficiency by the delivering party.

(b) If gas tendered under an Agreement fails to

conform to any of the quality specifications set forth above, the

party tendering the gas shall be responsible for any damages to the

facilities of Natural caused by such tender of non-conforming gas;

provided, however, that if Natural has consented to receive the

non-conforming gas, the tendering party shall not be liable to the

extent expressly stated in the consent.

as described in Section 17.1(a) of these General Terms and

Conditions.
