RATE SCHEDULE APAL-1

AUTOMATIC INTERRUPTIBLE PARKING AND LENDING SERVICE

(continued)

3.5 In circumstances where Transporter is unable to accept an Unpark

or Redelivery request or has suspended service under this Rate

Schedule, Transporter shall exempt such non-scheduled quantities

from the calculation of the Monthly Park/Loan Charge.

4. BALANCING AND RECALL OF ALLOCATED QUANTITIES

4.1 Shipper is expected to cause Nominations to or from the designated

Park and Loan Point to eliminate the Automatic Park and Loan

balance at the end of each Month.

(a) Transporter shall provide Shipper with Daily and cumulative

balances which are allocated to the Automatic Park and Loan

Agreement.

(b) Balances remaining on the Agreement at the end of a Month

shall be subject to the imbalance management provisions set

forth in Section 10 of the General Terms and Conditions.

4.2 Upon notification by Transporter, Shipper may be required to

submit a timely Nomination pursuant to Section 6.1 of the General

Terms and Conditions in the next available Nomination cycle to

eliminate no more than 10 percent of Shipper's outstanding

Automatic Park or Loan balance or up to 5,000 Dth on any Day,

whichever amount is greater, by the end of the next full Gas Day.

Shipper shall not be allowed to extend the duration of its

Agreement to accommodate such Unparking or Redelivery. Such action

is necessary to allow Transporter to fulfill higher requirements.

Transporter may allow additional time when operational conditions

permit. Such notices shall be provided by telephone, and then by

facsimile, e-mail, in writing or on Transporter's electronic

bulletin board. In the event a timely and valid Nomination is

submitted in response to notification by Transporter to remove

Parked quantities and/or return Loaned quantities, Shipper shall

be deemed to have complied with Transporter's notification for

that Gas Day.

Unless otherwise agreed by Shipper and Transporter; (a) any Parked

quantity not Nominated for removal within the period specified by

Transporter's notice pursuant to Section 4.2 of this Rate Schedule

or by the end of the term of an Agreement shall become the

property of Transporter at no cost to Transporter free and clear

of any adverse claims; (b) any Loaned quantity not returned within

the period specified by transporter pursuant to Section 4.2 or by

the end of the term of an Agreement shall be sold to Shipper at

150% of Transporter's Cash Out System Index Price.
