RATE SCHEDULE PDD

Preferred Deferred Delivery Service

A transportation rate and fuel is charged both into and out of a Field Area storage point.

Except as provided below with regard to a transportation point and its associated storage

point, a transportation rate and fuel is charged for delivery to the Ogden storage point.

If redelivery from Ogden is to a Market Area point, there is no additional transportation

or fuel charge. If the redelivery is to a Field Area point, the Field Area mileage/MID

transportation rate and fuel is charged. To the extent a volume is transported between a

pooling point and its associated storage point, no transportation fee or fuel shall be

assessed. With the exception of Ogden, to the extent a volume is transported from a

storage point to a transportation point other than its own associated transportation point

then a transportation fee and fuel will be assessed.

When the Ogden Storage point is used, the Shipper must use the same type of service

(i.e., firm or interruptible) to transport to and from the storage point, unless agreed to

otherwise by Northern on a non-discriminatory basis. However, in the event interruptible

transportation service was used injecting into the PDD account, capacity release may be

utilized, under the terms and conditions of Section 47, Capacity Release, to transport

quantities from the PDD account.
