GENERAL TERMS AND CONDITIONS

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

to such information shall be exempt at all times, including during a

Critical Time, from Operational Flow Orders requiring that gas flows

be conformed to nominations or to some percentage of nominations. If

the variance at a point (including a Central Delivery Point) exceeds

1,000 Dth per day, where Natural does have daily metering or access to

such information, the Balancing Service Charges shall apply to the

entire variance (in excess of any other applicable tolerance) except

as set out in the following sentence. A point operator shall be

exempted during both non-Critical and Critical Times from Balancing

Service Charges for any variance which is less than 1,000 Dth per day

(e.g., the Balancing Service Charges shall apply only to that portion

of any variance which is in excess of 1,000 Dth per day); provided,

however, that the 1,000 Dth per day shall be included in, and shall

not be in addition to the point operator's account under Section 11.3

of these General Terms and Conditions except to the extent the 1,000

Dth per day exceeds the otherwise applicable allowance for a point

operator account, in which latter case the point operator's account

shall be increased to the level required to accommodate the 1,000 Dth

per day, and except that the 1,000 Dth per day exemption applies

during Critical Times.

12.7 BILLING

(a) In the event Natural does not have all actual

information by the time the billings are to be sent, Natural may bill

Balancing Service Charges applicable to non-Critical Times based on

reasonable estimates. Such non-Critical Time Balancing Service Charges

will be assessed or revised as a result of the receipt or revision of

actual information.

(b) During a Critical Time, Natural and Shippers shall

rely on Natural's operational data posted on Natural's Interactive

Website to determine whether a Critical Time Balancing Service Charge

is applicable; provided, however, if a Shipper is convinced that

Natural's operational data is erroneous and promptly (by the end of

the next business day following the posting) communicates the error to

Natural, Natural and the Shipper shall work to resolve the discrepancy

and determine the appropriate measure of the Shipper's compliance with

applicable tolerances.

General Terms and Conditions, Balancing Service Charges shall be

applied to point operator's account as though point operator were a

Shipper, with percentage variances measured in relationship to total

confirmed nominations and delivery rights under Applicable Agreements

at the Delivery Point.
