GENERAL TERMS AND CONDITIONS (continued)

properly record the temperature of the gas flowing through

the meters. The arithmetic average of the temperature(s)

recorded shall be used in computing gas volumes.

(e) The specific gravity of the gas delivered shall be

determined by the use of a recording gravitometer, which

shall be checked at least once each month, or any other

method mutually agreed upon.

(f) The deviation of the natural gas from Boyle's Law shall be

determined by the use of the tables of formulae published by

the American Gas Association Par Research Project NX-19

corrected for carbon dioxide and nitrogen, or any

superseding applicable tables published by the American Gas

Association, or any method or methods mutually agreed upon.

Determinations of the molecular percentage of N2 and CO2 in

the gas shall be made within thirty (30) days after

commencement of deliveries and at leastquarterly thereafter.

The molecular percentage of N2 and CO2 thus determined will

be used to determine the supercompressibility factors during

the ensuing period, with corrections for specific gravity,

temperature and pressure. For the purpose of this

subparagraph, the results of the deviation tests of the

upstream pipeline delivering natural gas to Transporter

shall be accepted.

3.3 Determination of Receipts and Deliveries - For purposes of

determining the quantities of gas received at any Receipt

Point(s), Transporter will enter into an Operational Balancing

Agreement(s) ("OBA"), with any pipeline that operates inter or

intrastate pipeline facilities which interconnect with

Transporter's system.

(a) Allocation of Receipts - Unless prohibited by

applicable law or regulation, the quantities of natural

gas received by Transporter at any Receipt Point(s) shall

be allocated among Shippers and services in accordance

with allocation procedures contained in the OBA agreed to

by Transporter and the upstream pipeline serving that

Receipt Point.
