GENERAL TERMS AND CONDITIONS (Continued)

34. PRE-EXISTING CONTRACTS

Any contract between Pipeline and Customer which was executed prior to

and was in effect on September 3, 1993 shall be continued in effect

until such contract is replaced by an executed Service Agreement in the

form contained in this Tariff.

35. DETERMINATION OF DELIVERIES AND IMBALANCES

the actual imbalance ascribable to each service agreement to the

greatest extent possible. As minimum, allocations shall be

provided by both contract and location. Delivery point

allocations shall be performed at the lowest level of detail

facilities of any Customer is applicable to more than one

service agreement and Pipeline cannot ascribe the actual

imbalance to each individual service agreement, Pipeline will

attribute the total quantities of gas delivered to any

Customer to each service in the following sequence as applicable:

(i) The quantity of gas scheduled for delivery by the

Customer under the Customer's no-notice service

agreement;

(ii) The quantity of gas scheduled for delivery by the

Customer under the Customer's other firm service

agreements;

(iii) The quantity of gas scheduled for delivery under

the Customer's interruptible service agreements.

35.2 Customer's Responsibility. It is the responsibility of the

Customer to provide accurate and timely nominations of

quantities proposed to be received and delivered by Pipeline

under each of the Customer's service agreements; to maintain

equality between quantities actually taken by the Customer and

the Customer's scheduled quantities under each service

agreement, and to maintain a concurrent balance between receipts

and deliveries under each service agreement.
