INTERRUPTIBLE PARKING SERVICE

(Continued)

(b) The storage of Gas in amounts up to Customer's Maximum Park

Quantity provided that all Firm Storage Service storage needs have

been satisfied; and

(c) The withdrawal from storage on any Day and delivery of

Customer's Gas per Customer's nomination to the Point(s) of

Delivery up to Customer's Maximum Daily Withdrawal Quantity

("MDWQ") stated in Exhibit A of the Hub Services Agreement with

Customer, provided that all Firm Storage Service nominations or

withdrawals have been satisfied, and that Customer has a quantity

of Gas stored in Customer's Park Balance not less than the

quantity the Customer shall have nominated for withdrawal on such

Day.

To the extent storage capacity which is being utilized

by an Interruptible Customer hereunder is needed by TRES PALACIOS

in order to satisfy TRES PALACIOS' obligations to Firm Storage

Services, TRES PALACIOS shall require Customer to withdraw all, or

any portion of, the IP Gas quantities held in storage by TRES

PALACIOS for the account of Customer as specified by TRES

PALACIOS. Unless TRES PALACIOS otherwise agrees, Customer shall

be required to make ratable withdrawals. If Customer fails to

withdraw such IP Park Balance, then TRES PALACIOS may take, free

and clear of any adverse claims, title to such IP Park Balance as

Customer was instructed to withdraw. TRES PALACIOS' notice to

Customer may be given orally, but shall be confirmed in writing

via e-mail or facsimile to the Customer.

In the event that TRES PALACIOS retains and takes title to

any of Customer's Gas pursuant to this Section, TRES PALACIOS

shall credit the value of such gas, net of any costs incurred by

TRES PALACIOS to take title to and/or resell such Gas, in

accordance with the provisions of Section 32 of the General Terms

and Conditions of this FERC Gas Tariff.

In the event TRES PALACIOS needs to require Customer to

withdraw its Gas from storage pursuant to this Section, TRES

PALACIOS shall provide day-ahead notice to Customer that it must

withdraw Gas at its MDWQ during the next Gas Day. TRES PALACIOS

shall repeat this notice on a daily basis until all of Customer's

Gas is withdrawn from storage or until the circumstances

necessitating interruption are alleviated. In the event Customer

makes a timely nomination in response to a notification by TRES

PALACIOS pursuant to this paragraph, Customer's obligation to

comply with that notification shall be tolled until such time as

TRES PALACIOS' operational conditions allow TRES PALACIOS to

schedule the nomination.
