GENERAL TERMS AND CONDITIONS (Continued)

12.5 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 Petal 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 above Section 12.3 from the original due date until the date

actually paid.

12.6 Right to Audit. Both Petal 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 Petal 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 Petal 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 Petal 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.
