GENERAL TERMS AND CONDITIONS (continued)

6.7 Adjustment of Billing Errors. If, subject to the time limits

set forth in this Section 6.7, it shall be found that Shipper has

been overcharged or undercharged in any way whatsoever under the

provisions hereof and Shipper shall have actually paid the

invoices containing such overcharge or undercharge, then within

thirty (30) Days after the final determination thereof,

Transporter shall refund the amount of any such overcharge, or

shall invoice Shipper for the amount of the undercharge so

determined. Either party shall be entitled to seek an adjustment

to a Transporter's invoice allegedly containing an overcharge or

undercharge at any time during a period extending six (6) Months

from the date of such invoice, and the other party shall have an

additional period of up to three (3) Months to rebut the proposed

invoice adjustment, provided, however, that such time limits shall

not apply to precluded adjustments arising out of government-

required rate changes, and will not apply in case of deliberate

omission or misrepresentation, or mutual mistake of fact, and

parties' other statutory or contractual rights will not be

otherwise diminished by this provision.

6.8 Transporter's fuel reimbursement percentages will be

calculated on the basis of actual Fuel Usage divided by actual

throughput volumes. Electric power used as fuel for electric

driven compressors will be converted to equivalent volumes of gas

for purposes of calculating such fuel reimbursement percentages.

Transporter will prepare a report of actual fuel usage for each

twelve month period ending December 31 and file such report with

the Federal Energy Regulatory Commission not later than the

following April 1.
