basis, and on a firm basis pursuant to Rate Schedule FSS-1 or on a

recallable basis, and subject to any agreed-to FSS-1 injection or

withdrawal priorities. However, an FSS-1 Customer may not release its

right to capacity, and a Replacement Customer may not re-release such

capacity, for a period extending beyond the term of the original FSS-1

as apply to the original FSS-1 Customer. There is no limit on the number

of times the same firm capacity may be released.
