GENERAL TERMS AND CONDITIONS

when Shipper ceases operations at the facilities prior to the end of the

contracted term.

25.7 Overthrust shall bill Shipper for reimbursement of additional

facilities according to § 17 of these General Terms and Conditions.

25.8 Overthrust and Shipper may mutually agree that Shipper will pay

the cost of said facilities even though the addition of said facilities may

be economically beneficial to Overthrust or provide increased business

opportunities for Overthrust. Further, Overthrust and Shipper may mutually

agree to share the cost of said facilities.

25.9 Shipper may contract with Overthrust or a third party to install

such facilities, provided, however, that Overthrust shall install all taps

and related valves or check valves.

25.10 Shipper shall coordinate the construction of such facilities with

Overthrust so that Overthrust may reasonably have inspectors at the site

during construction. Shipper assumes full responsibility and liability and

agrees to hold Overthrust harmless from any liability of any nature arising

from the installation of such facilities by Shipper or by a third party for

Shipper.

25.11 Overthrust shall own, operate, and maintain such equipment

installed at Shipper's expense unless otherwise agreed to in writing by

Overthrust and Shipper. All such facilities owned and operated by Overthrust

must include any rights of way necessary to access facilities for inspection

and maintenance. Any such facilities constructed by Shipper or third parties

must be according to Overthrust's specifications. Overthrust must approve

design drawings and bills of materials, and construction shall be subject to

approval by Overthrust's inspectors.

25.12 This section pertains to facilities at receipt and delivery

points only. It is not intended to limit any party's ownership, operation,

installation or payment for facilities upstream of a receipt point or

downstream of a delivery point. It is the Shipper's responsibility to assure

that all facilities installed and owned by Shipper or any other party

upstream of a receipt point or downstream of a delivery point comply with all

applicable governmental regulations and design requirements for their

intended use (i.e., pressure, control, etc.).
