RATE SCHEDULE PDD

Preferred Deferred Delivery Service

7. NOMINATIONS AND SCHEDULING

Shipper shall nominate PDD service under this Rate Schedule in accordance

with the nomination deadlines set forth in Section 28 of the GENERAL TERMS

AND CONDITIONS of this Tariff.

8. ALLOCATION OF SERVICE

Shipper nominations shall be subject to confirmation by Northern which

shall be based on the best operating information available to Northern.

Service under this Rate Schedule shall be scheduled and confirmed only

after firm FDD service has been scheduled and confirmed by Northern.

Service under this Rate Schedule shall be scheduled and confirmed

prior to IDD service.

For purposes of allocating or curtailing service among Shippers under this

Rate Schedule, Northern may give service priority based upon the highest

total cost commitment to Shipper for PDD service. For the purposes of

allocating capacity under this Rate Schedule, Shippers willing to pay more

than the maximum tariff rate will be considered to be paying the maximum

tariff rate. Service may be allocated or curtailed on a pro-rata

basis among Shippers willing to pay the same total cost commitment to

Northern for such service.

9. NOTIFICATION FROM NORTHERN

Shipper may be required, upon notification from Northern, to cease or

reduce deliveries to, or receipts from, Northern's PDD service within the

gas day to protect firm FDD service or to comply with the parameters of

Shipper's PDD Service Agreement and Appendices. Further, Shipper may be

required to return deferred quantities and/or remove deferred quantities

upon notification from Northern. Such notification may be via e-mail or

posting on Northern's website. Northern's notification shall specify the

time frame within which deferred quantities shall be removed and/or

deferred quantities shall be returned, consistent with Northern's operating

conditions, but in no event shall the specified time be sooner than the

next gas day after Northern's notification. In the event that the

specified time for removal or return of gas quantities is the next gas day,

the time of required removal or return shall begin from the time that

Shipper receives actual notice from Northern. Notices required after

business hours for the next gas day will be provided to Shipper via

e-mail or posting on Northern's website. In the event that Shipper makes a

timely nomination in response to notification by Northern to remove

deferred quantities and/or return deferred quantities, the obligation of

Shipper to comply with the notification shall begin when Northern schedules

the nomination.

A. In the event that Shipper is required to return deferred quantities

and/or remove deferred quantities or deferred quantities are not

delivered or received in accordance with the daily or monthly

parameters outlined in any existing PDD Service Agreement and

Appendices, Northern and Shipper may mutually agree to an extended time

frame and/or modified terms of such Appendices. In the event that

Shipper and Northern are unable to come to such agreement, Northern

shall notify Shipper and Shipper shall deliver or receive the deferred

quantities within the time frame specified in Northern's notice, which

in no instance shall be less than one (1) calendar day. Any deferred

quantities not removed within the time frame specified by Northern's

notice shall become the property of Northern at no cost to Northern,

free and clear of any adverse claims. Any quantities not delivered for

deferral within the time frame specified by Northern's notice shall be

sold to Shipper at 150% of the System Average MIP, as defined in

Section 32 of this Tariff which may be modified from time to time.
