GENERAL TERMS AND CONDITIONS

(Continued)

5. Billing (Continued):

5.3 Examination of Records (Continued):

Any such books, records and charts delivered upon request

therefore shall be returned within twenty days after receipt

thereof. Both Seller and Buyer shall preserve all such books,

records, and charts or copies thereof for a period of at least

three years.

5.4 Correction of Billing Errors:

In the event an error is discovered in the amount billed in

any statement rendered by the Seller, such error shall be

adjusted within thirty days of the claim therefor, provided

that claim therefor shall have been made within twelve months

from the date of such statement.

6. Payment:

6.1 Payment: On or before the twentieth day of each month,

Buyer shall pay Seller, at Seller's General Office, the amount

due from Buyer for the preceding month as billed by Seller.

6.2 Unpaid Accounts: Should Buyer fail to pay the amount of

any bill for gas delivered, as herein provided when such

amount is due, interest on the unpaid account shall accrue at

the rate of six percent per annum from the due date until the

date of payment. If such failure to pay continues for thirty

days after payment is due, Seller in addition to any other

remedy it may have, may, after obtaining any requisite

authorization, suspend further delivery of gas until such

amount is paid, provided, however, that if Buyer in good faith

shall dispute the amount of any such bill or part thereof and

shall pay to Seller such amount as it considers to be correct

and at any time thereafter, within thirty days of a demand

made by Seller, shall furnish a good and sufficient surety

bond in amount and with sureties satisfactory to Seller,

conditioned upon the payment of any amount ultimately found

due upon such bill after a final determination which may be

reached either by agreement or judgment of the courts as may

be the case, then Seller shall not be entitled to suspend

further delivery of gas unless and until default be made in

the condition of such bond.

6.3 Extension of Time of Payment: If presentation of a bill

by Seller is delayed after the tenth of the month, the time of

payment shall be extended accordingly unless Buyer is

responsible for such delay.
