GENERAL TERMS AND CONDITIONS

(Continued)

13. MEASUREMENT

13.1 The unit of volume for measurement of all quantities of Gas wheeled, parked, loaned or stored

by ASC or delivered to and received from storage hereunder shall be one (1) cubic foot of Gas

at the base temperature of sixty degrees Fahrenheit (60 degrees F) and at an absolute pressure

of fourteen and seventy-three hundredths (14.73) pounds per square inch and dry. All

fundamental constants, observations, records, and procedures involved in determining and/or

verifying the quantity and other characteristics of Gas delivered hereunder shall, unless

otherwise specified herein, be in accordance with the standards prescribed in Report No. 3

of the American Gas Association, as now in effect and from time to time amended or supplemented.

All measurements of Gas shall be determined by calculation into terms of such unit. All

quantities given herein, unless expressly stated otherwise, are in terms of such unit.

Notwithstanding the foregoing, it is agreed that, for all purposes, the Btu content of the

Gas received and delivered by ASC hereunder shall be measured on a "dry" basis rather than

a fully saturated or "wet" basis. For Gas volumes reported in cubic meters, the standard

conditions are 101.325 kPa, 15 degrees C, and dry.

13.2 ASC shall install, maintain and operate, or cause to be installed, maintained and operated,

the measurement facilities required hereunder. Said measurement facilities shall be so equipped

with meters, recording gauges, chromatographs or other types of related and/or similar equipment

of standard make and design commonly acceptable in the industry, as to accomplish the accurate

measurement of Gas delivered hereunder. The retrieval of data and calibrating and adjustment

of meters shall be done by ASC or its agent.

14. BILLINGS AND PAYMENTS

14.1 Invoice. Not later than the ninth (9th) Business Day of each month, ASC shall provide Customer

(including a Replacement Customer) an invoice and any required backup data (which may be

transmitted by fax) setting forth (i) the charges due for the current Month; (ii) the total

quantity of Gas, stated in Dekatherms, received from and delivered to Customer hereunder during

the preceding Month(s), with applicable Point(s) of Receipt and Point(s) of Delivery properly

identified, and the amount due therefor; and if applicable, (iii) the amount of Customer's Gas

in storage as of the close of the preceding Month and information sufficient to explain and support

any adjustments made by ASC in determining the amount billed. If actual quantities are not

available by the ninth (9th) Business Day of the month, ASC may invoice based on best available

data subject to adjustment to actual at a later date. Quantities at points where Operational

Balancing Agreements exist shall be invoiced based on scheduled quantities.
