INTERCONNECTION AGREEMENT

ARTICLE I

(Cont'd)

(I) In the event that the installation, operation and/or maintenance

of any compressor used in Transporter-Related Compression Operations requires

(in Transporterþs reasonable judgment) modification(s) to any facility owned

or operated by Transporter, the cost of such modification(s) shall be borne

by Operator.

(J) Operator shall, at its own cost and expense, (i) obtain, provide

Transporter with, and maintain any easement(s) or other land interest(s)

which, in Transporterþs judgment as to type and extent, are reasonably

necessary for the installation, operation and maintenance of receipt and

related facilities; and (ii) provide Transporter with a copy of the recorded

instruments evidencing such land interests and Transporterþs beneficial

interest therein.

(K) Measurement and other equipment shall be installed, at Operatorþs

expense, at each Exhibit A Receipt Point facility, which, in Transporterþs

reasonable judgment, may be necessary to accommodate the deliveries of gas

received and projected to be received by it at the Receipt Points (the

þReceipt Facilitiesþ). The normal operation, calibration, maintenance,

adjustment and repair of the Receipt Facilities shall be performed by

Transporter at its initial expense, provided, however that Operator shall

maintain and calibrate any of the Exhibit A Receipt Points which deliver less

than three hundred (300) Dth per month. Modifications to Receipt Facilities

resulting from changes in Operatorþs operations shall be performed at

Operatorþs cost and expense.

(L) Operator shall, at its own cost and expense, provide, operate and

maintain in safe and efficient operating condition such regulators, relief

valves, and other equipment as may be necessary in Transporterþs reasonable

judgment to avoid excessive pressures (and the risk of such pressures) in

facilities owned and operated by Transporter or its customers.
