storage for Shipper's account at any time during the year. In no event

shall the balance of gas stored in Shipper's account exceed Shipper's

Storage Capacity as defined under Section 6 of this Rate Schedule.

Transporter will schedule available injection capacity consistent with

the priority of service provisions and curtailment policy in Section 12

After the commencement of an annual Storage Cycle, withdrawals from

Shipper's Available Working Gas may be replaced both to maintain

deliverability and to restore the quantity available for withdrawals.

Additional working gas may also be injected during the Storage Cycle;

provided, however, that Shipper's Unavailable Working Gas as defined in

Section 8 above shall not be available for withdrawal during the current

Storage Cycle.

13. WITHDRAWALS IN EXCESS OF FIRM ENTITLEMENT (BEST-EFFORTS WITHDRAWALS)

Shipper may nominate to withdraw quantities in excess of Shipper's

Contract Demand on a best-efforts basis; provided, however, that the

total quantity withdrawn may not exceed the level of Shipper's Available

Working Gas. Transporter may make such excess withdrawal, consistent

with the priority of service provisions contained in Section 12 of the

General Terms and Conditions.
