GENERAL TERMS AND CONDITIONS

(Continued)

2. Measurement (Continued)

(i) Correction of Metering Errors. If, upon test, the measuring

equipment is found to be in error by not more than one percent (1%),

previous recordings of such equipment shall be considered accurate in

computing deliveries, but such equipment shall be adjusted at once to

record accurately. If, upon test, the measuring equipment shall be

found to be inaccurate by an amount exceeding one percent (1%), at a

recording corresponding to the average Hourly rate of flow for the

period since the last preceding test, then any previous recordings of

such equipment shall be corrected to zero error for any period that

is known definitely or agreed upon between Transporter and

Shipper/Operator. In case the period is not known or agreed upon by

Transporter and Shipper/Operator, such correction shall be for a

period equal to one-half of the time elapsed since the date of the

last test.

(j) Failure of Measuring Equipment. In the event any measuring equipment

is out of service or is found registering inaccurately and the error

is not determinable by test or by previous recordings, receipts or

deliveries through such equipment shall be estimated and agreed to by

the parties upon the first of the following methods which is

feasible:

(i) By correcting the error if the percentage of error is

ascertainable by calibration, special test, or mathematical

calculation.

(ii) By using the registration of any check meter or meters, if

installed and accurately registering.

(iii)By estimating the quantity of receipt or delivery based on

receipts or deliveries during preceding periods under similar

conditions when the measuring equipment was registering

accurately.

(k) Inspection of Equipment and Data: The reading, calibrating, and

adjusting of electronic computer components and/or mechanical

recording instruments thereof shall be done only by the equipment

owner or such owner's representative, unless otherwise agreed upon.

Both Transporter and Shipper 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 measuring equipment; provided, however, failure of

either Transporter or Shipper to witness such an operation shall not

affect the validity of such operation in any way. Unless the parties

otherwise agree, each party shall preserve all original test data,

charges and other similar records in such party's possession, for a

period of time prescribed by NAESB Standard 4.3.4.
