GENERAL TERMS AND CONDITIONS

13. BILLINGS AND PAYMENTS (continued)

13.1 Transportation Invoice. (continued)

Where the TSP allocates to a lower level (more detailed) than

the SR contract level and where:

- The Confirming Parties confirm at a higher level (less detailed)

than the nomination level; and,

- A SR has submitted more than one nomination line item to the TSP;

the TSP should employ the TSP's tariff allocation methodology (including,

where applicable, employing the other Confirming Party(ies)' PDAs) to

allocate gas to the confirmation detail level.

The TSP should then either: i) accept and employ a PDA from such SRs or

ii) employ the SR's ranks supplied in the nomination.

Where a TSP accepts PDAs from a SR (as specified in i) above and the SR

does not provide a PDA, the TSP should employ the tariff allocation

methodology.

(j)[NAESB WGQ Standard 2.3.60] At a location which is not covered by an

OBA, a Confirming Party should submit a Pre-determined Allocation (PDA)

to the allocating party at a level that is based on the allocating

party's business practice, but, in no event will such PDA be at a lower

level (more detailed) than that level of information exchanged between

such parties during their confirmation process.

(k)[NAESB WGQ Standard 2.3.61] A Pre-determined Allocation (PDA) may not

be used to allocate gas to a nominatable transaction that was not

identified in the nomination or confirmation process, as applicable,

absent prior mutual agreement among the Confirming Parties and the

party being allocated to in such transaction. In the event of a

conflict between this standard and the Transportation Service

Provider's existing tariff or general terms and conditions, the latter

will prevail.

(l)[NAESB WGQ Standard 2.3.62] Except in cases where the Percentage or

Operator Provided Value method of allocation is being employed, where

there is:

(i) sufficient gas to fulfill all scheduled quantities at a location, a

Pre-determined Allocation (PDA) should not result in a quantity

being allocated to a party, contract or transaction, as applicable,

that is less than the corresponding scheduled quantity(ies) for that

party, contract or transaction, as applicable,
