INTERRUPTIBLE STORAGE SERVICE

(b) Force Majeure Curtailment or Interruption may be ordered

by Seller as to service being performed by its system at

any time when Force Majeure affects or in Seller's

judgment threatens to affect Seller's ability to provide

service, upon the giving of such notice as is reasonable

under the circumstances.

(1) Without regard to any other remedy provided by law

or by the provisions hereof, Seller shall be

entitled to seek an order from the Commission or

any other appropriate tribunal requiring

compliance with curtailment or interruption

ordered by Seller in compliance with this Section

6.9 or any directive from any governmental

authority having jurisdiction in the premises.

(2) Seller may at any time notify Buyer of an

interruption pursuant to Section 6.9 herein

above, in which event Buyer must immediately

cease deliveries to or receipt of gas from

Seller, in whole or in part as directed by

Seller, and may be required by Seller to withdraw

all or any part of the gas being held by Seller for

Buyer's account. If Buyer is required by Seller to

withdraw gas being held by Seller for Buyer's

account, Buyer shall be required to accept such gas

over a period of sixty (60) days. In such instance,

the Volume Withdrawal Charge shall apply to any

withdrawal overrun quantities. After this sixty

(60) day period, any gas not withdrawn which Seller

has requested Buyer to withdraw under this Section,

shall be retained by Seller.
