Substitute Original Sheet No. 49 Substitute Original Sheet No. 49 : Effective

GENERAL TERMS AND CONDITIONS

based first on the request for service or contract

effective date, and then, if two or more shippers have

the same request for service date, the service shall be

prorated based on the requested daily volumes. Firm

shippers shall be interrupted pro rata based on their

contracted-for demand. Nothing in this provision shall

limit Transporter's right to interrupt service on any

other reasonable basis (including pro rata interruption

within a class of service) in order to insure system

integrity.

9.3 Transporter shall provide Shipper five days' notice

of any interruption, or as much notice as is possible, in

order to permit Shipper to make the election available

under 9.2. Such notice shall state the discounted

rates being paid by other shippers, the quantities being

transported at such rates and the estimated reduced

quantities of gas that can be transported.

9.4 In the event gas supply shortages at Delivery points

occur due to capacity constraints, such shortages shall

be handled under the following procedure:

(a) If any Shipper of Transporter experiences or

anticipates a supply emergency which could cause

injury to essential human needs and minimum plant

protection, such Shipper shall utilize to fullest

extent possible all of Shipper's existing gas supply

arrangements, including storage inventories and

available self-help measures to alleviate such

emergency prior to requesting assistance from

Transporter and other Shippers pursuant to this

section.

(b) Any assistance required to resolve a supply

emergency will be based, to the maximum extent

possible, on voluntary, market-based arrangements

involving a sale of gas by a willing seller to the

Shipper experiencing the emergency shortage, at a

rate to be negotiated by the parties to this sale.

Such transaction could involve the pre-arrangement

of portfolios of divertable supply, or short-term

arrangements through the use of Transporter's

electronic bulletin board or any other arrangement

acceptable to the parties to this sale.
