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 its Interactive Website 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 its Interactive Website or EDI if received through

its Interactive Website or via EDI if received via EDI. Such

notification of acknowledgment and acceptance will be within

fifteen (15) minutes of receipt via its Interactive Website if

received via Trailblazer's 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 which can be

used are matching of supply sources with specified customers and

combinations of methodology types. Different methods may be

submitted for overages or underages. If the parties cannot agree,

Section 12.1(b) shall apply.
