RECEIPT POINT

OPERATIONAL BALANCING AGREEMENT (Continued)

correct any CIQ during such 30-day period, Controlling Party will be required

to use a currently effective Rate Schedule FT-1 or IT-1 Service Agreement.

The terms, conditions and rates for such transportation service shall be

subject to the provisions of the Rate Schedules and applicable provisions of

the General Terms and Conditions of Transporter's Tariff. If the CIQ is not

resolved during this 30-day period, Transporter and Controlling Party shall be

required to cash-out any remaining CIQ. For any "positive" remaining CIQ,

where the Controlling Party has delivered more gas at the POR than was

scheduled, Transporter and Controlling Party shall utilize a cash-out

procedure whereby the CIQ at the time of termination will be divided by the

total scheduled receipts under the ROBA for the 30 days immediately preceding

the date of termination in order to determine the applicable percentage of

"Excess Receipts". For any "negative" remaining CIQ, where the Controlling

Party has delivered less gas at the POR than was scheduled, Transporter and

Controlling Party shall utilize a cash-out procedure whereby the CIQ at the

time of termination will be divided by the total actual receipts under the

ROBA for the 30 days immediately preceding the date of termination in order to

determine the applicable percentage of "Deficient Receipts". The Index Price

Multiplier applicable to the resulting percentage as shown below will be

multiplied by the applicable Index Price described below and such price will

be applied to any CIQ remaining at the end of the 30-day correction period.

The resulting dollars will be paid by Transporter to Controlling Party for any

positive CIQ or by Controlling Party to Transporter for any negative remaining

CIQ.
