NO-NOTICE STORAGE AND TRANSPORTATION SERVICE - FIRM

(Continued)

2.4 Authorized Overrun Service (continued)

(e) Shipper may request Transporter to accept injections into

storage resulting in Shipper's Gas in Place to exceed

Shipper's MAC.

(i) Shipper must obtain Transporter's prior consent for such

overrun service for quantities in excess of Shipper's

MAC to be considered Authorized Overrun Quantities. If

Transporter's prior consent is not obtained, the excess

quantities shall be treated as Unauthorized Overrun

quantities.

(ii) When approved by Transporter, Authorized Overrun

injection or withdrawal requests are for full Day

quantities.

2.5 Subject to the limitations of the Reservoir Integrity Inventory

Limit (see Section 1 of the General Terms and Conditions),

quantities Delivered to the Point(s) of Delivery specified in the

Agreement and/or Segmentation Points of Delivery on any Day under

any of Transporter's transportation rate schedules which are in

excess of Shipper's requirements at such Point(s) of Delivery, shall

be accounted for as Receipt Quantities under this rate schedule and

shall be deemed to be injected into Storage for Shipper's account.

Likewise, subject to the same limitations, Shipper's requirements on

any Day at the Point(s) of Delivery specified in the Agreement which

are in excess of quantities Delivered under Transporter's

transportation rate schedules shall be deemed to be withdrawn from

storage for Shipper's account up to Shipper's ADWQ. Shipper's

storage inventory shall be adjusted to account for all quantities

deemed injected or withdrawn pursuant to this provision. However, if

due to the limitations of the Reservoir Integrity Inventory Limit or

MDIQ, Gas cannot be injected into storage, transportation imbalance

measures (as addressed in Sections 10 and 11 of the General Terms

and Conditions) will apply or service may be curtailed, or both. If

imbalances occur, Transporter will seek Shipper's immediate

cooperation to eliminate them. If necessary, Transporter will issue

Operational Flow Orders to eliminate imbalances under this Rate

Schedule.
