GENERAL TERMS AND CONDITIONS

(continued)

6. MEASURING EQUIPMENT (continued)

(c) If no tests have been performed to determine the degree of inaccuracy, or if the

measuring equipment is out of service, the quantity of gas shall be estimated:

(l) By using the registration of any existing and agreed upon check equipment

considered by parties concerned to be registering accurately, or, in the

absence of such facilities,

(2) By correcting the error if the quantity or percentage of error is

ascertainable by calibration, test, or mathematical calculation; or if

neither of the two foregoing procedures is applicable,

(3) By relating the quantity of deliveries to deliveries during periods under

similar conditions when the measuring equipment was deemed to have been

registering accurately.

6.6 Preservation of Records. Each party shall preserve for a period of at least two years

all test data, charts and other similar records.

7. RECEIPT AND DELIVERY PRESSURES

Gas shall be received by Algonquin for the account of Customer at each Point of Receipt

at a pressure sufficient to enter Algonquin's system at the required rate of flow without

requiring a reduction in the pressure on Algonquin's system unless Algonquin, in its reasonable

discretion, expressly agrees to do so in the effective service agreement between Algonquin and

Customer. In no event shall gas be received at a pressure in excess of Algonquin's Maximum

Allowable Operating Pressure.

Algonquin shall deliver gas to Customer at each Point of Delivery at a pressure equal to

or greater than the pressure set forth in the effective service agreement between Algonquin and

Customer, unless otherwise agreed.
