Interruptible Storage Service

2. APPLICABILITY AND CHARACTER OF SERVICE (Cont'd.)

2.3 Service hereunder shall consist of the receipt of natural gas

delivered to storage facilities utilized by Transporter pursuant to

Shipper's IT Service Agreement; the injection of such gas into such

storage facilities, the storage and withdrawal of that gas, and the

delivery of that gas, after reductions as set forth in the ISS

Service Agreement and Section 3 of this ISS Rate Schedule, into

Transporter's transmission facilities for subsequent transportation

pursuant to Shipper's IT Service Agreement.

2.4 The ISS Service Agreement shall specify the Maximum Daily Injection

Quantity, Maximum Daily Withdrawal Quantity, Maximum Storage

Quantity, Injection Period, Withdrawal Period, and Storage Period

applicable to Shipper.

2.5 To the extent storage capacity which is being utilized by a Shipper

hereunder is needed by Transporter in order to satisfy or to

accommodate Transporter's obligations to firm transportation or

storage customers, Transporter shall require Shipper to withdraw

all, or any portion, of the gas quantities held in storage by

Transporter within thirty (30) days of Transporter's notice to

Shipper. If Shipper fails to arrange for the withdrawal from

storage of the quantities specified by Transporter in its notice,

despite the availability of capacity for the withdrawal of

Shipper's gas under its ISS Service Agreement and the transporta-

tion of Shipper's gas under its IT Service Agreement, Transporter

shall take title to Shipper's ISS Storage Balance that Shipper was

instructed to withdraw, free and clear of any adverse claims.

Transporter's notice to Shipper may be verbal and in such case

shall be followed by a written confirmation.

2.6 An ISS Service Agreement with a primary term of one year or longer

shall continue in effect beyond the expiration of the primary term

until terminated by either party as of the end of a Storage Period,
