Unless otherwise agreed upon, Horizon will install,

maintain and operate or cause to be installed, maintained and

operated, measuring stations equipped with flow meters and other

necessary metering and measuring equipment by which the volumes of

gas received and Equivalent Volumes delivered hereunder shall be

determined. Shipper may install check measuring equipment at its

own cost and expense; provided such equipment shall be so installed

as not to interfere with the operations of Horizon. Horizon and

Shipper, in the presence of each other, shall have access to the

other's measuring equipment at all reasonable times but the

reading, calibrating and adjusting of electronic computer

components and/or mechanical recording instruments thereof and the

changing of charts shall be done only by the equipment owner or

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

Horizon 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 Horizon or Shipper to witness such an operation shall not

affect the validity of such operation in any way. The records from

such measuring equipment shall remain the property of its owner,

but upon request, each will submit within ten (10) days to the

other its records and charts, together with calculations therefrom,

for inspection, subject to return within thirty (30) days after

receipt thereof. The measurement equipment of Shipper shall be for

check purposes only and, except as expressly provided herein, shall

not be used in the measurement of gas for purposes hereof.




Orifice meters shall be installed and gas volumes

computed, in accordance with the standards prescribed in ANSI/API

2530 entitled, "Orifice Metering of Natural Gas," which

incorporates Gas Measurement Committee Report #3 of the American

Gas Association, revised and reprinted, September 1969, and any

subsequent amendments Horizon may adopt in the exercise of its

reasonable judgment.
