GENERAL TERMS AND CONDITIONS

----------------------------

(e) Properly submitted and confirmed firm service

nominations at primary points will supersede any secondary point

service. Properly submitted and confirmed nominations at

secondary points within a path created by primary points will

supersede secondary point service outside the path unless the

capacity constraint is only at the point. Confirmed nominations

within MDQ at a secondary point by a holder of firm service will

interrupt service at that point under any interruptible Rate

Schedule.

(f) The primary Receipt and Delivery Points define

the primary path(s), including the direction of "forward" flow for

the primary path(s). Shippers may nominate service at secondary

points so that the direction of flow is the same as or the

opposite ("backhaul") from the primary path direction of flow, but

if opposite, such nomination shall be treated as being outside the

primary path.

6.4 POOLING POINT

Service at the pooling point shall be governed by

Section 11 of these General Terms and Conditions. Trailblazer

shall determine the volumes which can be accommodated at the

pooling point as follows:

Trailblazer shall evaluate the capacity available

both: (1) upstream and at Receipt Points for gas tendered

pursuant to the Agreement(s) under which gas is nominated for

delivery to the pooling point; and (2) downstream and at Delivery

Points under the Agreement(s) pursuant to which gas is nominated

to be received from the pooling point. Gas shall not be confirmed

at the pooling point to the extent capacity constraints exist

which affect any such receipts or deliveries, applying the

priorities set out elsewhere in this Section.
