(5) To rectify imbalances or to conform physical

flows to nominations to the extent consistent with the specific

Rate Schedule;


(6) To maintain System integrity; or


(7) If there is a dispute over title, ownership

or right to tender or to receive gas.


Without limitation to the foregoing, Horizon shall have the right

to reduce receipts or deliveries of natural gas on any day below

Shipper's MDQ to permit maintenance, repair, overhaul, replacement,

or construction of pipelines, compressors, metering, regulating, or

other transmission facilities and equipment, or to maintain System

integrity; provided, however, that with respect to routine repair

and maintenance, Horizon will attempt to schedule such activity

during a period when it will not result in curtailment to firm

services, or when such curtailment will be minimized, after

consulting with the Shippers which could be affected.


(b) For the purposes of scheduling and curtailing gas,

all firm services shall have priority within MDQ over all

interruptible services. All firm services at primary points shall

have equal priority to Horizon's System capacity. Service

requested at secondary points shall have the priority described in

Section 3.3. To the extent capacity does not exist to provide for

all volumes nominated by Shippers on a firm basis within MDQ at

primary points and along any path defined by primary points under

all firm Rate Schedules, scheduling and curtailment shall be pro

rata based on confirmed nominations, within MDQ, on any portion of

Horizon's System affected by a capacity constraint.


(c) For Shippers under all firm services, Horizon

shall provide notice of any curtailment or of any scheduling

restriction as far in advance as feasible. Horizon shall attempt

to provide at least two (2) days' prior notice, unless more timely

action is necessary to respond to a Force Majeure situation, to

balance the Agreement to the extent consistent with the applicable

Rate Schedule, or to maintain System integrity.
