Each gas day, any difference between scheduled quantities to and from Shipper's point of service identified

above shall be deemed by Transporter to be an auto park or auto loan under this Appendix A (i.e., an auto park

for any positive difference, an auto loan for any negative difference). If Shipper chooses an AS or IPP Point

as its point of service, above, Transporter shall account for any applicable ratchet provisions (identified in

AS Rate Schedule Section 4(b)(ii) and IPP Rate Schedule 3(b)(ii)) in its calculation of auto park and auto loan

quantities, and only scheduled quantity differences outside of the ratchet percentages shall be deemed auto

parks or auto loans.

RATES:

The maximum Account Balance Charge set forth in the Tariff from time to time shall apply to all service provided

under this Master Auto PAL Agreement; provided, Transporter from time to time may grant a discount of the

Account Balance Charge to Auto PAL Shippers, consistent with Section 3 of the Master Auto PAL Agreement, at a

particular Point of Service, by posting such discount details on its Electronic Bulletin Board at least two

business days in advance of the discount's effective date.

The Account Balance Charge shall be assessed daily on Shipper's Auto PAL Account Balance. No Account Balance

Charge shall be assessed on any day Shipper's Account Balance is zero.

For the first two calendar months immediately following the effective date of the Auto PAL service feature on

Transporter's system, a 1,000 Dth "safe harbor limit" shall apply to Auto PAL Account Balances. Specifically, a

Shipper with an effective Master Auto PAL Agreement shall be entitled to maintain an Auto PAL Account Balance of

up to 1,000 Dth for no charge during this two-month "safe harbor limit" period. If a Shipper exceeds a 1,000

Dth Auto PAL Account Balance at any time during this two-month period, Shipper shall pay the Auto PAL Account

Balance Charge on that portion of Shipper's Auto PAL Account Balance in excess of 1,000 Dth.

In no event is Transporter obligated to provide service under this Master Auto PAL Agreement and the Appendix A

for amounts greater than the Maximum Cumulative Park/Loan Quantity identified in the Agreement, or for time

periods outside the Term Commencement and Ending Dates.
