event of a base tariff maximum and/or minimum rate change, wherein the

or a percentage of the maximum base tariff rate (as it may change from

time-to-time), the Replacement Shipper will be obligated to pay:

(a) for capacity release transactions that are subject to the

maximum base tariff rate pursuant to FERC regulations: the lesser

of the awarded bid rate and the new maximum base tariff rate

unless the awarded bid rate is less than the new minimum rate, in

which case the new minimum rate will apply for the remaining term

of the release.

(b) for capacity release transactions that are not subject to the

maximum base tariff rate pursuant to FERC regulations: the greater

of the minimum base tariff rate and the awarded bid rate for the

remaining term of the release.
