Firm Storage Service

4. BILLING ADJUSTMENTS

If during the Injection Period Transporter is unable to inject into

storage quantities of gas nominated during such period by Shipper for

injection and made available to Transporter, then the Storage Demand

Charge and the Storage Capacity Charge shall be reduced in the

following manner:

If, at the end of the Injection Period, Shipper's Storage Gas Balance

is less than Shipper's Maximum Storage Quantity due solely to

Transporter's inability to inject gas within the limitations set forth

in this Rate Schedule, then the Storage Capacity Charge applicable for

the ensuing Withdrawal Period and Injection Period shall be that part

of the total Storage Capacity Charge herein provided which Shipper's

Storage Balance as of such date bears to Shipper's Storage Capacity.

5. STORAGE FIELD LOSSES

In the event of a loss of gas from one or more storage fields utilized

by Transporter resulting from force majeure, such loss shall be

allocated among Transporter and each Shipper receiving service under

the SS-1, SS-2, ESS, FSS or ISS Rate Schedule in proportion to the

quantities of gas (excluding base gas) of each in storage immediately

prior thereto as reasonably determined by Transporter, and if such

extraordinary loss exceeds the top gas balances of Transporter and all

such Shippers, such excess will be deemed to be from Transporter's

base gas.

Losses of gas from storage fields utilized by Transporter that are

not losses resulting 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, insurrections, 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.
