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 PPEC 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 PPEC 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 PPEC 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 PPEC or its agent.

14. BILLINGS AND PAYMENTS

14.1 Invoice. Not later than the ninth (9th) Business

Day of each month, PPEC 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 PPEC in

determining the amount billed. If actual quantities are not

available by the ninth (9th) Business Day of the month, PPEC 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.
