GENERAL TERMS AND CONDITIONS

17. MEASUREMENT AND MEASURING EQUIPMENT (Cont'd)

Southern Star shall have the right to request a test of the meter

facility of Shipper, and Shipper shall have the right to request a test

of the meter facility of Southern Star at reasonable intervals, no more

often than once in thirty days. IfSRE is found to exceed the limit

stated above, the party owning the orifice meter shall, at the request

of the other party, submit to the requesting party plans for

installation of pulsation suppression equipment within a thirty-day

period following such request, and shall install said equipment within a

reasonable period of time. If such plan is not submitted within the

thirty-day period, or equipment not installed within a reasonable time,

the requesting party shall have the option of shutting in the delivery.

Pulsation errors determined by use of the square root error indicator

(SREI) manufactured under a license from the Southern Gas Association

are to be used only for the purpose of indicating needed facility

modification and are not to be used for adjusting accounts.

Shippers, operators or producers shall use their best efforts to avoid

any equipment, including intermitters or timed motor-operated or gas-

operated valves, the use of which prevents Southern Star's metering

equipment from obtaining reliable measurements. If such equipment is

required in order for a well to produce, Southern Star will cooperate

with the producer to reach a mutually acceptable method of accounting

for any interference with measurement caused by the equipment.

begin on the first day of the month and end on the last day of the

month.

and audit the records, books of account, and charts of the other for a

period of one year prior to any audit request to the extent necessary to

verify the accuracy of any computation, statement or charge for such

service, and to verify compliance with the associated service agreement.

data by delivery point (meter setting). For this purpose, each party

shall retain all pertinent records in accordance with applicable

regulations. Each party shall provide the other with access to

personnel and records necessary to effectuate an examination and audit.
