GENERAL TERMS AND CONDITIONS

succeed by purchase, merger or consolidation to the properties of Shipper

shall be entitled to any part of the interest of Shipper under its service

agreement without the written consent of Overthrust.

24. SHIPPER'S FAILURE TO COMPLY WITH TERMS

Should Shipper fail to comply with the terms of its transportation

service agreement and the General Terms and Conditions of this FERC Gas

Tariff, Overthrust will, after obtaining appropriate abandonment

authorization from the Commission, terminate service to Shipper.

25. FACILITIES CONSTRUCTION AND REIMBURSEMENT

25.1 When new and/or expanded facilities are required to accommodate

receipt and/or delivery of gas under this FERC Gas Tariff, and Overthrust

determines that installation of such facilities will be economically

beneficial to Overthrust or provide increased business opportunities for

Overthrust and will not impair service to any firm Shipper or threaten the

integrity of Overthrust's system, Overthrust shall construct such facilities.

Overthrust may require Shipper to pay all construction costs, including any

filing fees and a reimbursement amount to compensate for federal income tax

effects associated with such facilities. Overthrust shall pay the cost of

such facilities when the criteria in this section are satisfied.

25.2 Overthrust shall pay for the cost of the modification or

construction of facilities required at receipt or delivery point(s) to

effectuate the receipt or delivery of natural gas hereunder, when the

construction or modification of such facilities is economically beneficial to

Overthrust.

For the purposes of determining whether a project to transport gas

is economically beneficial to Overthrust, Overthrust shall evaluate each

prospective project based upon the incremental cost of service of the

facilities to be constructed by Overthrust, and the incremental revenues that

Overthrust estimates will be generated as a result of constructing and/or

modifying such facilities.

25.3 In estimating the revenues to be generated, Overthrust will

calculate the revenues based upon the applicable transportation rates,

exclusive of any surcharges
