GENERAL TERMS AND CONDITIONS

4. MEASURING EQUIPMENT (Cont'd.)

4.2 Demand Meters. If the Rate Schedule according to which gas deli-

vered to Shipper is billed includes a demand charge based on the

Dth taken by Shipper on the day of greatest delivery during a

billing month, Transporter shall use meters suitable for determin-

ing such greatest daily delivery.

4.3 Check Meters. Shipper or Operator may install, maintain and

operate, at its own expense, such check measuring equipment as it

shall desire. Such equipment shall be so installed as not to

interfere with the operation of Transporter's measuring equipment

at or near the points of delivery. The Transporter shall have

access to such check measuring equipment at all reasonable hours,

but the reading, calibrating and adjusting thereof and the changing

of charts shall be done only by the Shipper or Operator.

4.4 Installation. All installations of measuring equipment, applying

to or affecting receipts or deliveries by Transporter, shall be

made in such manner as to permit an accurate determination of the

quantity of gas delivered and ready verification of the accuracy of

measurement. Reasonable care shall be exercised in the installa-

tion, maintenance and operation of any pressure regulating

equipment so as to avoid, as far as practicable, any inaccuracy in

the determination of the volume of gas delivered hereunder.

4.5 Access to Meters and Records. Transporter and Shipper or Operator

shall have the right to be present at the time of any installing,

reading, cleaning, changing, repairing, inspecting, testing,

calibrating, or adjusting done in connection with the other's

equipment used in measuring or checking receipts and deliveries of

gas. The records from such equipment shall remain the property of

their owner, but upon request, each will submit to the other its

records and/or charts, together with calculations therefrom, for

inspection and verification, subject to return within ten (10)

days after receipt thereof.

4.6 Measurement Equipment Failures. In the event measurement equipment

is out of service, or registering inaccurately, the quantity and/or

volume of gas received or delivered by Transporter shall be esti-

mated:
