2. APPLICABILITY AND CHARACTER OF SERVICE (continued)

2.4 With respect to the transportation component of the service

provided under this Rate Schedule, the rights, obligations,

limitations and operational conditions and restraints applicable

thereto shall be the same as those applicable under Rate Schedule

FT, unless otherwise specified in this Tariff.

2.5 The term of each Service Agreement under this Rate Schedule shall

commence at the beginning of a Storage Contract Year and extend

through one or more Storage Contract Years.

2.6 Shipper shall use best efforts to reduce its Working Gas Quantity

to zero (0) Dth within thirty (30) Days of the end of the Storage

Contract Year and in no event shall Shipper's Working Gas Quantity

on such date exceed twenty-one percent (21%)of the maximum

quantity specified by Transporter, pursuant to Section 3.2, during

the preceding Storage Contract Year.

2.7 Shipper shall reduce its Working Gas Quantity to zero (0) Dth by

the end of the Storage Contract Year in which the Service

Agreement terminates. If Shipper fails for any reason to withdraw

all of its Working Gas Quantity within thirty (30) Days following

such termination date, then Transporter shall retain possession of

and title to all such remaining Gas and Shipper shall relinquish

all claims thereto provided that such thirty (30) Day period shall

be extended proportionately if, and to the extent that, Shipper's

failure to withdraw is caused by Transporter's inability due to

operating or force majeure conditions to accommodate Shipper's

requests for withdrawal.

2.8 Shipper may convert its service under this Rate Schedule to

equivalent levels of firm transportation and firm contract storage

under Rate Schedules FT and FSS as provided in the Service

Agreement.

2.9 Unless otherwise agreed, Transporter will not provide service

under Rate Schedule NNTS to any Delivery Point without load flow

control devices if the market behind the Delivery Point is

connected to multiple transporters. As long as a NNTS Shipper's

Delivery Point qualifies for NNTS service, Transporter shall not

install flow control devices at any such Delivery Point.

2.10 In order to avoid or limit disruption of services from planned

operational outages at any Delivery Point under a Shipper's Rate

Schedule NNTS Service Agreement, the parties may agree on

alternative arrangements to mitigate the impact of such outages

during periods when Shipper may otherwise seek to utilize the

service.
