ISS-M RATE SCHEDULE

INTERRUPTIBLE STORAGE SERVICE WITH MARKET-BASED RATES (Cont'd)

fails to withdraw all of Shipper's ISQ by Shipper's Final Withdrawal Date, any quantities not

withdrawn will be forfeited automatically by Shipper to Transporter free and clear of all liens

and encumbrances. Transporter will post the forfeited quantities on its EBB as gas available for

sale to the highest bidder within a 24 hour notice period. The posting may provide as a

condition of sale that such gas be withdrawn from storage within a specified period of time.

Upon receipt of payment, Transporter will treat the forfeited gas proceeds as Penalty Revenues as

defined in Section 19.6 of the General Terms and Conditions.

(d) All penalties and charges assessed under this Section will be assessed and paid in

addition to all applicable rates and charges under this Rate Schedule, including any overrun

charges.

(e) If Shipper seeks to avoid any penalty provided for in this Section on the ground

that the charge was incurred because of a force majeure event as defined in Section 15 (Force

Majeure) of the General Terms and Conditions, Shipper must document the force majeure event to

Transporter. Transporter will waive penalties if the imbalance was caused by a bona fide force

majeure event.

(f) Transporter may waive its right to collect all or any portion of any penalties

assessed against Shipper or its right to retain all or any portion of gas, provided that any such

waiver is granted in a nondiscriminatory manner.
