 Article 6.

 MEASUREMENT AND TESTING 
 6.1. Measurement Equipment. Measurement of Shipper’s Gas shall take place at the Receipt Points. Shipper will install, or cause to be installed, at or near the Receipt Points, orifice meters or other measuring equipment
necessary in Gatherer’s judgment to accurately measure the volumes of Shipper’s Gas being delivered into the Gathering System to the extent such meters or other measuring equipment have not been installed as of the date of this Agreement.
Such measuring equipment shall be comparable to the measuring equipment of other parties delivering gas into the Gathering System. Shipper shall be responsible for, and bear the cost of, acquiring, installing, maintaining and operating such
measurement equipment. 
 6.2. Chart Integration. Gatherer shall be responsible for reading the meters at the Receipt Points. Gatherer
shall furnish, install, remove, and integrate all recording charts used in such meters in accordance with Gatherer’s standard practices. 
 6.3. Delivery Points. The measurement of and tests for quality of Shipper’s Gas redelivered at the Delivery Points shall be governed by and determined in accordance with the requirements of the receiving pipeline at each
Delivery Point. 
 6.4. Unit of Volume. The unit of volume for purposes of measurement shall be one (1) cubic foot of gas at a
temperature base of sixty degrees (60è) Fahrenheit and at a pressure base of fourteen and seventy-three one-hundredths (14.73) psia. 
 6.5. Testing Procedures. Shipper shall follow the meter calibrations schedule established by Gatherer for each meter on the Gathering System. Such
calibrations shall occur at least once every twelve (12) months but not more frequently than once every six (6) months. No testing, calibration, or adjustment of a meter or related equipment shall be performed without Gatherer first being
given five (5) days’ notice thereof and having the opportunity to be present. 
  

 6 

 6.6. Meter Inaccuracy. If, at any time, any meter is found to be out of service or registering
inaccurately in any percentage, it shall be adjusted at once by Shipper to read accurately within the limits prescribed by the meter’s manufacturer. If such equipment is out of service or inaccurate by an amount exceeding three percent
(3%) of a reading corresponding to the average flow rate for the period since the last test, the previous readings shall be corrected for the period that the meter is known to be inaccurate, or, if not known, a period of one-half ( 1/2) the elapsed time since the last test. The volume of Shipper’s Gas delivered during such period shall be
estimated by Gatherer either (i) by using the data recorded by any check measuring equipment if installed and accurately registered, (ii) by correcting the error if the percentage of error is ascertainable by calibration, test, or
mechanical calculation or, if neither such method is feasible, (iii) by estimating the quantity delivered based upon deliveries under similar conditions during a period when the equipment registered accurately. No volume correction shall be
made for metering inaccuracies of three percent (3%) or less. 
 6.7. Meter Testing. If Gatherer requests to have any
meter tested, then Shipper shall have the meter tested in the presence of and to the satisfaction of Gatherer. If the meter tested proves to be accurate within plus or minus three percent (3%) at its normal operating range, then the cost of
testing and recalibrating the meter shall be borne by Gatherer. Shipper will schedule all required tests within ten (10) days of a request by Gatherer. Shipper will notify Gatherer at least five (5) working days prior to the test of the
date, time, and location of such test. 
 6.8. Books and Records. Gatherer shall keep and maintain proper books of account during the
term of this Agreement and for a period of three (3) years thereafter showing (a) the total volume of Shipper’s Gas transported through the Gathering System from the Receipt Points to the Delivery Points and (b) the volume of gas
allocated to each Receipt Point. Gatherer shall also preserve, or cause to be preserved, for at least one (1) year all test data, charts, and similar data pertaining to the measurement and testing of Shipper’s Gas, unless a longer period
is prescribed by applicable regulations. Shipper shall have the right during normal business hours, after reasonable notice to Gatherer, to inspect Gatherer’s books and records not older than three (3) years from the date of request for
inspection. Such inspections shall take place at Gatherer’s office. Any costs attributable to such audits or inspections shall be borne by Shipper.

MEASUREMENT AND TESTING 
 6.1.
Measurement Equipment. Measurement of Shipper’s Gas shall take place at the Receipt . Points. Shipper will install, or cause to be installed, at or near the Receipt Points, orifice meters or other measuring equipment necessary in
Gatherer’s judgment to accurately measure the volumes of Shipper’s Gas being delivered into the Gathering System to the extent such meters or other measuring equipment have not been installed as of the date of this Agreement. Such
measuring equipment shall be comparable to the measuring equipment of other parties delivering gas into the Gathering System. Shipper shall be responsible for, and bear the cost of, acquiring, installing, maintaining and operating such measurement
equipment. 
 6.2. Chart Integration. Gatherer shall be responsible for reading the meters at the Receipt Points. Gatherer shall
furnish, install, remove, and integrate all recording charts used in such meters in accordance with Gatherer’s standard practices. 
 6.3. Delivery Points. The measurement of and tests for quality of Shipper’s Gas redelivered at the Delivery Points shall be governed by and determined in accordance with the requirements of the receiving pipeline at each
Delivery Point. 

 6.4. Unit of Volume. The unit of volume for purposes of measurement shall be one (1) cubic
foot of gas at a temperature base of sixty degrees (600) Fahrenheit and at a pressure base of fourteen and seventy-three one-hundredths (14.73) psia. 
 6.5. Testing Procedures. Shipper shall follow the meter calibrations schedule established by Gatherer for each meter on the Gathering System. Such calibrations shall occur at least once every twelve
(12) months but not more frequently than once every six (6) months. No testing, calibration, or adjustment of a meter or related equipment shall be performed without Gatherer first being given five (5) days’ notice thereof and
having the opportunity to be present. 
 6.6. Meter Inaccuracy. If, at any time, any meter is found to be out of service or
registering inaccurately in any percentage, it shall be adjusted at once by Shipper to read accurately within the limits prescribed by the meter’s manufacturer. If such equipment is out of service or inaccurate by an amount exceeding three
percent (3%) of a reading corresponding to the average flow rate for the period since the last test, the previous readings shall be corrected for the period that the meter is known to be inaccurate, or, if not known, a period of one-half(Y2)
the elapsed time since the last test. The volume of Shipper’s Gas delivered during such period shall be estimated by Gatherer either (i) by using the data recorded by any check measuring equipment if installed and accurately registered,
(ii) by correcting the error if the percentage of error is ascertainable by calibration, test, or mechanical calculation or, if neither such method is feasible, (iii) by estimating the quantity delivered based upon deliveries under similar
conditions during a period when the equipment registered accurately. No volume correction shall be made for metering inaccuracies of three percent (3%) or less. 
 6.7. Meter Testing. If Gatherer requests to have any meter tested, then Shipper shall have the meter tested in the presence of and to the satisfaction of Gatherer. If the meter tested proves to be accurate
within plus or minus three percent (3%) at its normal operating range, then the cost of testing and recalibrating the meter shall be borne by Gatherer. Shipper will schedule all required tests within ten (10) days of a request by Gatherer.
Shipper will notify Gatherer at least five (5) working days prior to the test of the date, time, and location of such test. 
 6.8.
Books and Records. Gatherer shall keep and maintain proper books of account during the term of this Agreement and for a period of three (3) years thereafter showing (a) the total volume of Shipper’s Gas transported through the
Gathering System from the Receipt Points to the Delivery Points and (b) the volume of gas allocated to each Receipt Point. Gatherer shall also preserve, or cause to be preserved, for at least one (1) year all test data, charts, and similar
data pertaining to the measurement and testing of Shipper’s Gas, unless a longer period is prescribed by applicable regulations. Shipper shall have the right during normal business hours, after reasonable notice to Gatherer, to inspect
Gatherer’s books and records not older than three (3) years from the date of request for inspection. Such inspections shall take place at Gatherer’s office. Any costs attributable to such audits or inspections shall be borne by
Shipper.
