GENERAL TERMS AND CONDITIONS

3. MEASURING EQUIPMENT (Continued)

3.3 Right of Access (Continued)

repairing, inspecting, testing, calibrating, or adjusting

done in connection with the other's measuring equipment.

The records from such measuring equipment shall remain the

property of the Person installing such equipment, but, upon

request, each will submit to the other its measurement

records, together with calculations therefrom, for

inspection, subject to return within 30 days after receipt

thereof.

3.4 Reasonable Care

Company shall exercise reasonable care in the installation,

maintenance and operation of its measuring equipment so as

to avoid any inaccuracy in the determination of the volume

and other attributes of gas received and delivered.

3.5 Testing Measuring Equipment

Company shall conduct tests to verify the accuracy of its

measuring equipment using means and methods acceptable to

Company and the Shipper or Shippers affected, at least once

each quarter, or at such other interval as may be mutually

agreed upon and at other times upon request of Shipper or

Shippers. Notice of the time and nature of each test shall

be given by Company to such Shipper or Shippers in advance

to permit convenient arrangement for the presence of the

other's representatives. If, after notice, a Shipper fails

to have a representative present, the results of the test

shall nevertheless be considered accurate until the next

test. All tests of such measuring equipment shall be made

at the expense of the Company, except that Shipper or

Shippers requesting a test shall bear the expense of such

test if the inaccuracy is found not to exceed two percent,

at a reading corresponding to the average hourly rate of

flow.
