GENERAL TERMS AND CONDITIONS (Cont'd)

deliveries to secondary delivery points under the FTS, NTS, NTS-S, TPS, SST and GTS Rate Schedules, and for

deliveries to secondary delivery points under the OPT Rate Schedule when not interrupted pursuant to the

provisions of the OPT Rate Schedule, Transporter shall allocate capacity among Shippers on a pro rata basis,

based upon those Shippers' respective nominated quantities. This priority shall apply where Shipper's

aggregate deliveries at primary and secondary delivery points do not exceed Shipper's Transportation Demand.

Any interruptions or other allocation reductions to Shipper's deliveries at secondary delivery points under

the OPT Rate Schedule shall not reduce Shipper's allowable days of interruption under that Rate Schedule.

(d) Secondary Delivery Points Under Rate Schedule OPT During Periods of Interruption. For

deliveries to secondary delivery points under the OPT Rate Schedule, Transporter shall allocate capacity among

Shippers on a pro rata basis, based upon those Shippers' respective nominated quantities. This priority shall

apply where Shipper's aggregate deliveries at primary and secondary delivery points do not exceed Shipper's

Transportation Demand. Any interruptions or other allocation reductions to Shipper's deliveries at secondary

delivery points under the OPT Rate Schedule shall not reduce Shipper's allowable days of interruption under

that Rate Schedule.

(e) Rate Schedule ITS, Overrun Quantities Under Rate Schedules FTS, NTS, NTS-S, TPS, SST, and OPT

and X-Rate Schedules.

(1) Where Shippers have nominated deliveries to commence on the first Day of the Month of

(i) quantities under the ITS Rate Schedule, (ii) overrun quantities under the FTS, NTS, NTS-S, TPS,

SST, or OPT Rate Schedules, or (iii) interruptible quantities under interruptible X-Rate Schedules set

forth in Volume No. 2 of this Tariff, Transporter shall award capacity to those Shippers offering to

pay the highest rate for service during that Month. Transporter shall allocate capacity among

Shippers offering to pay the same rate first to those Shippers flowing gas during the previous month,

pro rata based upon the quantities flowing on the fifth business day preceding the first Day of that

Month, up to but not exceeding such flowing quantities. Transporter then shall allocate any remaining

capacity equally among the remaining Shippers offering to pay the same rate for service during that

Month up to but not exceeding nominated quantities.

(2) Where Shippers have requested deliveries in excess of available capacity and

commencing other than the first Day of the Month of (i) quantities under the ITS Rate Schedule, (ii)

overrun quantities under the FTS, NTS, NTS-S, TPS, SST, or OPT Rate Schedules, or (iii) interruptible

quantities under interruptible X-Rate Schedules set forth in Volume 2 of this Tariff, Transporter shall

allocate any available capacity on the basis of the highest rate. Where requested deliveries at the

same highest rate exceed available capacity, Transporter shall allocated capacity first to those

Shippers flowing gas on a pro rata basis, based upon respective confirmed nominations; and second to

all remaining Shippers based upon the order in which Transporter received nominations from those

Shippers (equally to any Shippers submitting nominations on the same day).

(3) If intraday nominations require an allocation of the pipeline system, the following

will describe the circumstances that allow a higher priority service to bump a lower priority service.

(a) Evening Nomination Cycle: For nominations received by 6:00 p.m. CT and to be

effective at the start of the upcoming gas day, nomination increases at a primary point under

Rate Schedules FTS, NTS, NTS-S, TPS, SST, GTS and OPT will not bump nominations at a secondary

point under these same rate schedules that are submitted and scheduled within the Timely

Nomination Cycle. Nomination increases submitted under Rate Schedules FTS, NTS, NTS-S, TPS,

SST, GTS and OPT whether at primary or secondary points will have priority over nominated and

scheduled quantities under Rate Schedule ITS and overruns under the firm rate schedules and may

bump such quantities effective at 9:00 a.m. CT the next day. Nomination increases submitted

under Rate Schedule ITS and overruns under the firm rate schedules shall be subject to

available unscheduled capacity and will not bump scheduled quantities. Transporter shall notify

Shippers being bumped as a result of intraday nominations by 10:00 p.m. C.T.
