GENERAL TERMS AND CONDITIONS

(Continued)

8.2 Monthly Imbalances. The calculation of the monthly

imbalances shall depend upon whether there is an

Operational Balancing Agreement in effect at the

delivery point(s). Where an Operational Balancing

Agreement is in effect, monthly imbalances under an

Agreement shall be calculated each calendar Month by

comparing the volumes scheduled for the Month to actual

receipts during that Month. Where an Operational

Balancing Agreement is not in effect, monthly imbalances

under an Agreement shall be calculated each calendar

Month by comparing actual measured volumes delivered

during the Month to actual net measured volumes received

(with the appropriate deduction for Gas Unaccounted For

during that Month on the basis of Equivalent Volumes.

In each case, where the comparison that is specified

does not yield an equivalency, then the following

transportation fees and offsetting and netting

procedures shall apply:

Imbalances under a Shipper's different agreements will

be netted together to obtain the Shipper's total Monthly

Imbalance ("TMI"). The TMI will be shown on the monthly

billings sent to Shippers. To facilitate the trading or

offsetting of Shipper's TMI, UTOS will post on its

Internet Website, on or before the ninth Business Day of

the Month, the TMI of any Shipper that has not notified

UTOS in writing that the Shipper does not elect to have

that information posted. Shippers or their agents may

post and trade imbalances on and across contracts with

Shippers or their agents until the close of business on

the seventeenth Day of the Month (Trading Period).

Parties that agree to trade all or part of an imbalance

must notify UTOS in writing on or before the seventeenth

Business Day of the Month through submission of an

Confirmation of Agreement to Trade Imbalances form;

otherwise, such trade shall not be effective. Upon

receipt of an Imbalance Trade Confirmation, UTOS will

send an Imbalance Trade Notification to the trading

parties by noon (Central Clock Time) the next Business

Day. Any Shipper imbalance remaining after the Trading

Period will be cashed out as described in Section 8.3.
