GENERAL TERMS AND CONDITIONS

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

12. DETERMINATION OF DAILY RECEIPTS

12.1 To the extent feasible, all volumes received by

Trailblazer at a Receipt Point shall be allocated in accordance with

the confirmed nominations for that point. In the event the actual

volumes received by Trailblazer do not equal the confirmed

nominations for that point, any underage or overage will be

allocated as follows:

(a) First, in accordance with the effective

predetermined allocations (PDAs) submitted by those entities

(Allocators) owning or controlling the gas being delivered to

Trailblazer. An operational balancing agreement (OBA) is one type of

a PDA. Shipper agrees that such an allocation is binding on Shipper.

(b) Then, if there is no effective PDA, pro rata to the

extent applicable based on confirmed nominations or transfer

nominations, as applicable. Shipper agrees that such an allocation

is binding on Shipper.

12.2 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, except that

no other PDAs need be submitted if an OBA is in effect at a point.

Unless otherwise agreed, all PDAs must be submitted to Trailblazer

through DART or through EDI before the start of the gas Day the PDA

is to be effective. Such PDA shall specify how any underage or

overage from the confirmed nominated volumes should be allocated

among the entities listed on the PDA. Trailblazer shall acknowledge

receipt and acceptance of the PDA through DART or EDI if received

through DART or via EDI if received via EDI. Such notification of

acknowledgment and acceptance will be within fifteen (15) minutes of

receipt 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 which can be used are percentages,

pro rata, ranking, swing, matching of supply sources with specified

customers, and combinations thereof. Different methods may be

submitted for overages or underages.
