Advanced Interruptible Loan Service obligations and extensions of the service

shall have priority as follows:

(a) The order of priority relating to service requests for service

the formula set forth in Section 3.2(c), above.

(b) Should two or more requests under Advanced Interruptible Storage

Service or Advanced Interruptible Loan Service by Customers have the same

priority as follows:

(a) The order of priority relating to service requests for service under

the ISS and ILS Rate Schedules and Authorized Overrun Quantities under all

Rate Schedules shall be based on the average daily interruptible storage,

loan, injection, withdrawal or overrun charge agreed to by Caledonia and

Customer, with the highest charge calculated on a daily basis given highest

shall be pro rata based on ADWQ, ADIQ or MSC, as applicable. Interruption of

service to Interruptible Storage Service Customers, Interruptible Loan Service

Customers and to Customers utilizing Authorized Overrun Quantities under all

Rate Schedules shall be based on the charges paid by Customer, with the

transaction at the lowest price to Caledonia being interrupted first. Any

ties shall be interrupted on a pro rata basis.
