2. IMBALANCES

The actual physical flow at the Point of Interconnect each

month will be determined and communicated by AWP in writing as

soon as possible but in no case later than the tenth (10th)

Business Day of the month following the month in question.

Actual physical flows shall be determined pursuant to AWP's

then effective Federal Energy Regulatory Commission ("FERC")

Gas Tariff. Any Operational Imbalance shall be agreed to

within thirty (30) days of the date the Operational Imbalance

is agreed to in writing on the attached Exhibit "I" or within a

mutually agreeable longer period of time.

The parties shall use their best reasonable efforts to correct

any Operational Imbalance in a manner mutually agreed to by The

Parties.

All quantities of gas hereunder, received or delivered, to

correct an Operational Imbalance, shall be reported in thermal

units which are determined pursuant to AWP's then effective

FERC Gas Tariff.

3. SUSPENSION OF OBLIGATION

In the event that a capacity constraint occurs on either

Party's pipeline system which results in curtailment of

quantities through the Point of Interconnect, the Party on

whose system the constraint has occurred shall determine the

reallocation of quantities to the shippers. The confirmed

nominations shall be changed to reflect such reallocation of

capacity pursuant to Paragraph 1. above.

Notwithstanding anything to the contrary in this Agreement,

confirming nominations as actual physical flow and accounting

for the imbalances may be temporarily suspended in the event

that either Party discovers or anticipates that the physical

flow at the Point of Interconnect varies or will vary

significantly from the confirmed nominations due to

extraordinary circumstances such as significant interruption of

transportation service, severe cold weather, a hurricane or

some other event that significantly affects the gas supplies

available for delivery at the Point of Interconnect. Such

suspensions will be effective on the date verbal notice is

provided by the suspending Party's Gas Control personnel to the

other party's Gas Control personnel. Such verbal notice shall

be confirmed in writing no later than the second Business Day

following the day of desired suspension. Each
