8.3 Failure to Meet Specifications

Should any gas tendered for delivery by Shipper fail at any time to conform to any of the

specifications of this section, Transporter shall notify Shipper of the failure and Transporter

may suspend all or a portion of the receipt of any such gas if it will jeopardize operation of

Transporter's system or will cause Transporter to suffer an economic loss; and Transporter shall

be relieved of all obligations for the duration of such time as the gas does not meet the

specifications; provided however that Transporter shall have the right to waive the

specifications set forth in this section if, in Transporter' sole opinion, Transporter is able

to accept such non-conforming gas without adversely affecting Transporter's operations.

8.4 Commingling

It is recognized that gas delivered by Shipper will be commingled with other gas transported by

Transporter. Accordingly, the gas of Shipper shall be subject to such changes in heat content

as may result from such commingling and Transporter shall, notwithstanding any other provision

in this FERC Gas Tariff, Second Revised Volume No. 1, herein, be under no obligation to

redeliver for Shipper's account, gas of a heat content identical to that caused to be delivered

by Shipper to Transporter.

On or before the fourth (4th) business day of each Month, Transporter shall e-mail to Shipper a

notification that the statement of the amount due for the preceding Month under Transporter's

applicable rate schedule(s) is available for viewing on Transporter's Web Site. In computing

amounts due, Transporter may utilize estimates of the quantity of gas received from or delivered

to Shipper during a Month in place of actual quantities when actual quantities are not

reasonably available; provided, however, that adjustments shall be made as soon as is reasonably

possible for differences between estimated and actual quantities. Any additional invoice backup

shall accompany or precede the invoice.

When information necessary for billing purposes is in the control of Shipper, Shipper shall

furnish that information to Transporter on or before the second (2nd) business Day of the Month

following the Month of delivery.

Both Transporter and Shipper have the right to examine, at reasonable times, books, records and

charge or computation made under or pursuant to any of the provisions hereof.
