ISS RATE SCHEDULE

INTERRUPTIBLE STORAGE SERVICE

(Continued)

(c) The withdrawal from storage on any Day of

Customer's Gas per Customer's nomination up to Customer's Maximum

Daily Withdrawal Quantity ("MDWQ") as stated in the executed

Interruptible Storage Service Agreement and the delivery of such

Gas to the Point(s) of Delivery, provided that all Firm Storage

Service nominations for withdrawal have been satisfied and

Customer has a quantity of Gas in Customer's Interruptible Storage

Inventory not less than the quantity Customer shall have nominated

for withdrawal on such Day.

2.2 To the extent Interruptible storage capacity which is

being utilized by an Interruptible Customer hereunder is needed by

PPEC in order to satisfy PPEC's obligations to Firm Storage

Service Customers, PPEC shall require Customer to withdraw all, or

any portion of, the ISS Gas quantities held in storage by PPEC for

the account of Customer as specified by PPEC. Unless PPEC

otherwise agrees, Customer shall be required to make ratable

withdrawals. If Customer fails to withdraw such ISS Gas from

storage, PPEC may take, free and clear of any adverse claims,

title to such ISS Storage Inventory as Customer was instructed to

withdraw. PPEC's 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 PPEC retains and takes title to any of

Customer's Gas pursuant to this Section, PPEC shall credit the

value of such gas, net of any costs incurred by PPEC 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 PPEC needs to require Customer to withdraw its

Gas from storage pursuant to this Section, PPEC shall provide day-

ahead notice to Customer that it must withdraw Gas at its MDWQ

during the next Gas Day. PPEC 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basis until all of Customer's Gas is withdrawn from storage or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 PPEC pursuant to this paragraph, Customer's

obligation to comply with that notification shall be tolled until

such time as PPEC's operational conditions allow PPEC to schedule

the nomination.
