7.2 In the event Pipeline has insufficient capability to receive and inject

into storage all quantities of gas requested by Customer to be injected on any

day, Pipeline shall schedule injections among such Customers on a first-

come/first-served basis determined by the date and time their injection

nomination for such day was received by Pipeline; provided, however, in no event

shall the scheduled injection quantity be in excess of the quantity determined

pursuant to Section 7.1.

7.3 To the extent the injection, storage and withdrawal capacity which is

being utilized by Customers hereunder is needed by Pipeline in order to satisfy

Pipeline's firm obligations under Rate Schedules SS-1 and FSS-1 or to accommodate

allocate the necessary interruption of storage service hereunder based upon a

last-in/first-out basis determined by the month gas was injected hereunder. In

the event there is more than one Customer who injected gas in a given month, any

interruption of service for such storage quantities shall be allocated pro rata
