GENERAL TERMS AND CONDITIONS

All nominations for service, including firm overrun, will be required to be

electronically nominated by path, i.e. specific receipt point to specific

delivery point, provided that for nomination purposes, a Point of Delivery

in the Market Area or Argus Zone in the Field Area may be a currently established

Operational Zone, applicable to deliveries to the facilities of a single LDC. For

Shipper(s) with combined service for both Market Area and Field Area, nominations

from the Field Area to the Market Area (or vice versa) must include a nomination

to and from the NNG Field/MKT Demarcation (POI 37654). Northern will accept

facsimile nominations in the event of a failure of electronic nomination

communication equipment. Overrun quantities shall be nominated as a separate

transaction. All nominations must include shipper-defined begin dates and end

dates. Additionally, the upstream and/or downstream contract information and

rankings must be provided for a nomination to be valid.

The receiver of a nomination initiates the confirmation process. The party that

would receive a Request for Confirmation or an unsolicited Confirmation Response

may waive the obligation of the sender to send.

Northern may accept "standing nominations," excluding intra-day nominations, for

the then existing term of the Service Agreement. The term "standing nominations"

shall mean a nomination of a specific volume to remain in effect until the earlier

of:

i) the requested ending date of such nomination; or

ii) a request by Shipper to change such nomination;

provided however, the term of the nomination is within the term of the Service

Agreement.

Auto-balancing is where a Shipper may request Northern to automatically schedule

volumes into or out of storage on behalf of the Shipper at such times when a

Shipper is allocated at a supply/market point as long as the Shipper currently

holds an FDD/IDD service agreement and as long as the scheduled volume is within

the storage parameters. To the extent imbalances or receipt and delivery point

variances occur, Shipper shall be responsible for any applicable charges. To

request this service, Shipper shall submit an executed Storage Balancing Option

form located on Northern's website.

With respect to the timely nomination/confirmation process at a receipt or

delivery point, in the absence of agreement to the contrary, the lesser of the

confirmation quantities should be the confirmed quantity. If there is no response

to a Request for Confirmation or an unsolicited Confirmation Response, the lesser

of the confirmation quantity or the previously scheduled quantity should be the

new confirmed quantity.

To the extent Northern's other scheduling requirements are met, a Shipper may

redirect scheduled quantities to other receipt points upstream of a constraint

point or delivery points downstream of a constraint point at any of Northern's

subsequent nomination cycle(s) for the subject Gas Day, under the same contract,

without a requirement that the quantities be rescheduled through the point of

constraint.

With respect to the processing of requests for increases during the intraday

nominations/confirmation process, in the absence of agreement to the contrary, the

lesser of the confirmation quantities should be the new confirmed quantity. If

there is no response to a Request For Confirmation or an unsolicited Confirmation

Response, the previously scheduled quantity should be the new confirmed quantity.

With respect to the processing of requests for decreases during the intraday

nomination/confirmation process, in the absence of agreement to the contrary, the

lesser of the confirmation quantities should be the new confirmed quantity, but in

any event no less than the elapsed-prorated-scheduled quantity. If there is no

response to a Request For Confirmation or an unsolicited Confirmation Response,

the greater of the confirmation quantity or the elapsed-prorated-scheduled

quantity should be the new confirmed quantity.
