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 DART if

received via DART or via EDI if received via EDI. Trailblazer's

acceptance is contingent on Trailblazer being able to administer the

allocation submitted by the Allocator. Examples of allocation methods

that can be used are percentages, pro rata, ranking, swing, and

combinations thereof. 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.
