Interruptible Storage Service

5. STORAGE FIELD LOSSES (Cont'd)

from force majeure, as defined below, will be deemed to be gas from

Transporter's top gas balance, and, to the extent such losses exceed

Transporter's top gas balance, such excess will be deemed to be from

Transporter's base gas. For purposes of this Section 5, a loss of gas

resulting from force majeure is a loss caused by any acts of God,

strikes, lockouts, acts of the public enemy, wars, blockades, insurrec-

tions, riots, epidemics, landslides, lightning, earthquakes, fires,

storms, floods, washouts, arrests and restraints of rulers and peoples,

civil disturbances, explosions, breakage or accident to machinery or

lines of pipe, line freeze-ups, or similar causes.

Shipper is placed on notice that Transporter may recognize storage gas

losses for rate and accounting purposes. Such losses shall be valued at

the current replacement cost of gas. After accounting recognition of

any such loss, Transporter shall record and maintain a regulatory asset

account which shall be maintained until Transporter's next general rate

change filing under Section 4 of the Natural Gas Act. In any of

Transporter's general rate change filings, Transporter may propose to

amortize storage gas losses through its base rates. This provision

shall apply to storage gas losses incurred but unamortized as of the

date upon which this provision becomes effective, and to those incurred

after that date.

6. WITHDRAWALS UPON TERMINATION OF SERVICE

Not less than thirty (30) days prior to the termination of storage

service provided to any Shipper under this rate schedule, Transporter

will notify Shipper of Shipper's Storage Balance. If the Storage

Balance is positive, then the Shipper will withdraw such quantities

within thirty (30) days of the termination of the storage service.

Transporter will take title to all such gas not withdrawn without

recourse on the thirty-first day after the termination of the storage
