TRANSPORTATION GENERAL TERMS AND CONDITIONS

(Continued)

16. MISCELLANEOUS PROVISION

16.1 Waiver of Default: No waiver by either GTN or Shipper of any

default by the other in the performance of any provisions of an

executed Transportation Service Agreement shall operate as a waiver

of any continuing or future default, whether of a like or different

character.

16.2 Assignability: An executed Transportation Service Agreement shall

bind and inure to the respective successors and assignees of GTN

and Shipper thereto, but no assignment shall release either party

thereto from such party's obligations without the written consent

of the other party, which consent shall not be unreasonably

withheld; provided, however, nothing contained herein shall give

Shipper the right to reassign or broker its right to ship the

quantities of gas specified in the Transportation Service

Agreement on GTN's system to others. Further, nothing contained

herein shall prevent either party from pledging, mortgaging or

assigning its rights as security for its indebtedness and either

party may assign to the pledgee or mortgagee (or to a trustee for

the holder of such indebtedness) any money due or to become due

under any service agreement.

16.3 Effect of Headings: The headings used throughout these

Transportation General Terms and Conditions, the rate schedules to

which they apply, and the executed Transportation Service

Agreements are inserted for reference purposes only and are not to

be considered or taken into account in construing the terms and

provisions of any paragraph nor to be deemed in any way to qualify,

modify or explain the effects of any such terms or provisions.

17. TRANSPORTATION SERVICE AGREEMENT

17.1 Form: Shipper shall enter into a contract with GTN utilizing GTN's

appropriate standard form of Transportation Service Agreement.

17.2 Term: The term of the Transportation Service Agreement shall be

agreed upon between Shipper and GTN at the time of the execution

thereof.

17.3 Evergreen Provision: GTN and Shipper may mutually agree to include

an evergreen provision in Shipper's Firm Transportation Service

Agreement that will allow the agreement to continue in effect

beyond its primary term. GTN will make evergreen provisions

available to shippers on a not unduly discriminatory basis.
