ESS RATE SCHEDULE

Enhanced Storage Service

3. RATE (Cont'd)

3.4 During withdrawal of gas hereunder, Transporter will retain a

quantity of gas equal to the product obtained by multiplying the

quantity of gas withdrawn by the percentage set forth on Sheet No.

6 as "surface operating allowance."

3.5 Except as provided by valid rule or regulation, Transporter is not

obligated to offer to store or store gas at any rates less or

allowances than the maximum rates and allowances specified for this

rate schedule on Sheet No. 6; however, nothing precludes Transport-

er from charging a rate between the maximum and minimum rate or

retaining an allowance less than the allowance specified for

service under this Rate Schedule as set forth on Sheet No. 6.

4. MINIMUM MONTHLY BILL

The minimum monthly bill shall be the sum of the Storage Demand Charge

and the Storage Capacity Charge.

5. 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.
