GENERAL TERMS AND CONDITIONS

(Continued)

11. SERVICE AGREEMENT AND SERVICE CONDITIONS (Continued)

11.6 Post-Termination Obligations. Upon termination, a Service

Agreement will cease to have any force or effect, save as to any

unsatisfied obligations or liabilities of either party arising under the

Service Agreement prior to the date of such termination, or arising

thereafter as a result of such termination. Provided, however that this

provision will not supersede any abandonment authorization which may be

required.

11.7 Extension of Firm Service Agreement(s) Prior to Expiration. Prior

to the expiration of the term of a firm Service Agreement(s) and prior

to Transporter posting the availability of such capacity for competitive

bid subject to a Shipper's right of first refusal, if any, Transporter

and Shipper may mutually agree to negotiate the terms of Shipper's

agreement(s) in exchange for Shipper's extension of all or a part of its

existing service(s) under its agreement(s). Extensions of such Service

Agreement(s) will be negotiated on a case-by-case basis in a not unduly

discriminatory manner. To the extent that Transporter and Shipper have

mutually agreed to extend such service, the posting and bidding

requirements of Section 25.2(b) of the General Terms and Conditions of

the Tariff will not apply.

11.8 Shipper Buy-Out of Firm Service Agreement.

(a) General. When Transporter is negotiating with a Shipper that

is willing to subscribe to posted unsubscribed capacity or

capacity offered in an open season, Transporter may agree to

allow such Shipper the right to buy out of the resulting

Service Agreement in its entirety.

(b) Eligibility. Transporter, on a not unduly discriminatory

basis, will only agree to a buy-out if, in Transporter's

reasonable judgment, it is financially beneficial to

Transporter.
