anticipates that it will have available to satisfy Buyers' requests for services each

day, Seller will use the following order of priority and procedures.

give first priority to firm transportation service scheduled within firm

transportation contract entitlements. To the extent capacity remains, it shall

be allocated among Buyers in the following order:

(i) first, to Buyers scheduling services pursuant to Section 2.8 of Seller's

FT and FT-G Rate Schedules, or Section 2.5 of Seller's FTN Rate Schedule,

or Section 2.6 of Seller's FDLS Rate Schedule; and

(ii) then, ratably as a class, to Buyers paying the maximum rate under the IT

Rate Schedule, contracts or Service Agreements scheduling interruptible

service to feed downstream firm service arrangements (as described in

Section 3.9 of Rate Schedule IT), regardless of the date of such

contracts or Service Agreements, provided however, Buyers paying a

negotiated rate which exceeds the maximum rate will be considered for

purposes of this Section 28.2(a)(ii) to be paying the maximum rate; and

(iii) then, to all other interruptible transportation Buyers pursuant to

Section 28.2(b).
