5.7 Measurement Equipment Inaccuracy and Failure

The quantity of Natural Gas received and delivered by

Transporter and delivered to Shipper or for Shipper's

account hereunder during periods when the measurement

equipment is out of service or registering

inaccurately shall be estimated as follows:

(a) If, upon test, any measurement equipment, the

readings of which are used in the registration,

integration, or computation of quantities of

Natural Gas hereunder, is found to be in error

to the extent that it introduces not more than

one percent (1%) measurement error, in the

individual measurement equipment affected,

previous records of such equipment shall be

considered accurate.

(b) If, upon test, any such above measurement

equipment is found to be in error, to the extent

that it causes the registered or computed

quantities of the instrument(s) so affected to

be in error, by an amount exceeding one percent

(1%) such instrument(s) affected shall be

corrected to zero (0) error for any part of the

period since the last test in which such error

is known to have existed or which may be agreed

upon by representatives of Transporter and

Connecting Party. In case the period of such

error is not known definitely or agreed upon,

such correction shall be for a period of

one-half («) of the elapsed time since the date

of the last test, but not exceeding a correction

period of thirty (30) days.
