OPERATIONAL BALANCING AGREEMENT (Continued)

1.5 Unauthorized deliveries - Upon notice by Viking under an Operational Flow Order (OFO),

Operator shall confirm its deliveries to the terms and conditions of the OFO. If Operator

fails to conform its deliveries to the terms and conditions of the applicable OFO, the excess

quantities will be treated as unauthorized deliveries and will be subject to a charge as set

forth in Article III of the General Terms and Conditions of Viking's FERC Gas Tariff.

ARTICLE II

CORRECTION OF OPERATIONAL IMBALANCES

2.1 Corrections During the Month - Estimated metered quantities, or actual metered quantities

where available, shall be used by Viking for purposes of adjustments under this Section on a

daily basis during the production month to determine the estimated Operational Imbalance at

(all of) the Receipt Point(s). Viking shall make the estimated Daily and Monthly Operational

Imbalance (at each Receipt Point) available to Operator within three (3) business days after

each production day. Adjustments in nominations and actual deliveries may be made by Viking

or Operator during the production month to adequately control imbalance levels. If Operator

fails to take such corrective action, Viking may, upon 48 hours notice, adjust the

nominations and actual receipts during the remainder of the production month to adequately

control imbalance levels. Any such adjustments will be incorporated in the daily nominations

confirmed between Viking and Operator.

2.2 Corrections in Subsequent Periods - As soon as practicable following the close of each month,

Viking will send Operator a statement setting forth the Monthly Operational Imbalance

existing at the end of the prior month. Any Monthly Operational Imbalance shall be corrected

in cash in accordance with Rate Schedule LMS of Viking's FERC Gas Tariff Volume No. 1, unless

the parties mutually agree otherwise. For purposes of correcting imbalances in cash in

accordance with Rate Schedule LMS, any difference between actual deliveries and confirmed

nominations will be treated as "Excess Receipts."

2.3 Measurement of Operational Imbalance - Any gas received or delivered pursuant to this

Agreement shall be adjusted for variation in Btu content. Measurement of gas for all

purposes shall be in accordance with Viking's FERC Gas Tariff.

2.4 Operational Integrity - Nothing in this Article II shall limit Viking's right to take action

as may be required to adjust receipts of gas in order to alleviate conditions which threaten

the integrity of its system.
