2.4 Subject to the limitations of the Young Reservoir Integrity

Inventory Limit (see Section 8.3 of the General Terms and

Conditions), quantities Delivered to the Point(s) of Delivery

specified in the Agreement and/or High Plains Segmentation Points of

Delivery on any Day under any of Transporter's High Plains

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 Young 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rate schedules shall be deemed to be withdrawn from storage for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 YADWQ. 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withdrawn pursuant to this provision.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 Young Reservoir Integrity Inventory Limit, YMDWQ

or YMDIQ, Gas cannot be injected into, or withdrawn from, storage as

necessary, 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.
