GENERAL TERMS AND CONDITIONS

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

13. DETERMINATION OF DELIVERIES

13.1 PREDETERMINED ALLOCATIONS

In accounting for the volumes delivered by Trailblazer,

in circumstances where multiple services are provided at any Delivery

Point, the sequence of volumes delivered shall be determined by a

predetermined allocation agreement between Trailblazer and the

operator of the facilities immediately downstream of the point at

which Trailblazer delivers gas. The upstream or downstream party

providing the point confirmation should submit the PDA to the

allocating party after or during confirmation and before the start of

the gas Day. In the absence of such an agreement, Sections 13.2 and

13.3 shall control. Any new or proposed change to the methodology

should be sent to Trailblazer before the start of the gas Day on

which the methodology is to be effective. Trailblazer shall confirm

receipt of the methodology within fifteen (15) minutes via its

Interactive Website if received via its Interactive Website or via

EDI if received via EDI. Trailblazer's acceptance is contingent on

Trailblazer being able to administer the allocation submitted by the

Allocator. Allocation methodology types upon which two parties may

agree are: ranked, pro rata, percentages, swing and operator

provided value. Other examples of allocation methods that can be

used are combinations of methodology types. Different methods may be

submitted for overages and underages.

13.2 DELIVERY SEQUENCE

Unless otherwise agreed, gas at any Delivery Point shall

be deemed to have been delivered in the following sequence:

(a) Volumes scheduled under firm transportation

Agreements consistent with confirmed nominations and within MDQ;

(b) Volumes scheduled under interruptible transportation

Agreements consistent with confirmed nominations and within MDQ;

nominations;

(d) Additional volumes shall be allocated pro rata based

on confirmed nominations, but not to exceed the applicable MDQ, among

ITS Agreements under which Shippers nominated that day; and

(e) Any remaining volumes shall be allocated as

Unauthorized Overrun Gas pro rata based on confirmed nominations

among ITS Agreements under which Shippers nominated that day.
