14.5 Billing Disputes. If Customer withholds payment of

any disputed amount as authorized herein, Customer shall within

ten (10) days after the due date of the disputed invoice submit to

PPEC a written explanation of the dispute and any available

supporting documentation. The parties shall then cooperate in

good faith to resolve such dispute as expeditiously as possible,

and the portion, if any, of such disputed amount eventually

determined to be due shall bear interest at the rate stated in

Section 14.4 above from the original due date until the date

actually paid.

14.6 Right to Audit. Both PPEC and Customer shall have

the right at their own expense to examine and audit at any

reasonable time the books, records (including measurement, billing

and payment) and charts of the other to the extent necessary to

verify the accuracy of any statements or charges made under or

pursuant to any of the provisions of Customer's Storage Service

Agreement. Upon request, Customer shall also make available to

PPEC for audit purposes any relevant records of the Transporters

to which Customer has access. A formal audit of accounts shall

not be made more often than once each Contract Year. Any

inaccuracy will be promptly corrected when discovered; provided,

however, that neither PPEC nor Customer shall be required to

maintain books, records or charts for a period of more than two

(2) Contract Years following the end of the Contract Year to which

they are applicable. Neither PPEC nor Customer shall have any

right to question or contest any charge or credit if the matter is

not called to the attention of the other in writing within two (2)

years after the end of the Contract Year in question.

15. TAXES

If at any time PPEC is required to remit any taxes assessed

on the Gas pursuant to Customer's Storage Service Agreement, then

PPEC shall have the right to collect from Customer such taxes,

including any penalties and interest. Customer agrees to

reimburse PPEC for the taxes assessed on the Gas, including any

penalties and interest, within fifteen (15) days of the date of

invoice from PPEC. Customer shall furnish PPEC information,

satisfactory to PPEC, to enable PPEC to comply with any reports

required by state or federal government and agencies. Customer

recognizes that PPEC may be required to file federal and state tax

returns, and Customer agrees to furnish PPEC with adequate

information pertaining to the taxation on the Gas. Customer shall

coordinate such filings with PPEC.
