GENERAL TERMS AND CONDITIONS (Cont'd)

(b) Except as prescribed in Section 8.1(a) of the General Terms and Conditions, if confirming

parties cannot agree upon an allocation methodology, "pro rata based upon confirmed nominations" shall be used

as the default method.

and other entities. No Difference balanced in-kind shall be allocated to any Shipper at the receipt or

delivery points covered by the OBA. If an interstate pipeline charges Transporter for Differences in the OBA,

however characterized, Transporter shall charge such interstate pipeline an equivalent and offsetting charge.

If Transporter is unable to charge or collect such equivalent and offsetting charges for such Differences,

Transporter, on an as-billed basis, shall allocate and bill such charges to Shippers responsible for the

imbalance at the point of interconnection at which the Difference giving rise to the charges occurred.

(d) Where an OBA exists between interconnecting parties, a PDA is not necessary.

(e) Changes to a PDA may be made prospectively during the Month. Only one PDA may be submitted per

allocation period. Transporter may in its reasonable discretion make retroactive reallocations of

transactions to correct for errors. Otherwise, no retroactive reallocations of any transactions shall be

permitted without the approval of Transporter and the agreement of those Shippers with Service Agreements

affected by such retroactive reallocations, provided that the agreement by such affected Shippers shall not be

unreasonably withheld.

(f) PDAs shall remain in effect until a replacement PDA is received from the interconnecting

operator or upstream title holder; provided, however, that PDAs shall be updated at the beginning of each

month. A new allocation detail may be needed when a nomination changes.

(g) If the PDA is provided using EDI, Transporter shall respond with an EDI confirmation indicating

receipt of the PDA within 15 minutes, and whether there are any errors associated with the PDA.

8.4 (a) Prior Period Adjustments. Except for minor variations as agreed to by all affected parties,

prior period measurement adjustments will be taken back to the production month and reflected as such on

invoices, imbalance statements and allocation statements. Missing or late measurement data shall be estimated

and actuals will be treated as a prior period adjustment, with the measuring party to provide the estimate.

Measurement corrections shall be processed within 6 months of the end of the production month, with a 3 month

rebuttal period. This provision does not apply in cases of deliberate omission, or misrepresentation, or mutual

mistake of fact. No Party's other statutory or contractual rights are diminished by this provision.

(b) Disputed Allocations. Disputed allocations shall be communicated to Transporter within 6

months of the initial month-end allocation, with a 3-month rebuttal period. This time limitation shall not

apply in the case of deliberate omission or misrepresentation, or mutual mistake of fact. No Party's other

statutory or contractual rights are diminished by this provision.

8.5 For operational monitoring at electronically measured locations, allocated quantities shall be

available one business day after the gas has flowed at the end of the Gas Day. The scheduled quantity shall

be made available at locations which are not measured electronically. Transporter shall provide allocation

statements to the appropriate party for the meters it operates each month.
