GENERAL TERMS AND CONDITIONS

through its rates, the security required shall be reduced accordingly. Where

facilities are constructed to serve multiple Shippers, an individual

Shipper's obligation hereunder shall be for no more than its proportionate

share of the cost of the facilities. This provision is in addition to and

shall not supersede or replace any other rights that Overthrust may have

regarding the construction and reimbursement of facilities.

(f) Overthrust shall not take any action under this §10.1 which

conflicts with any order of the U.S. Bankruptcy Court.

10.2 Deterioration of Credit.

(a) (i) If at any time Overthrust reasonably determines, based

on adequate information available to it, that a Shipper is no longer

creditworthy under this § 10 of these General Terms and Conditions, or if

Shipper fails to maintain assurance of future performance under this § 10 of

these General Terms and Conditions, Overthrust may notify such Shipper in

writing (which writing shall set forth the basis for Overthrust's decision)

that it has five (5) Business Days to provide Overthrust with security

consistent with this § 10 of these General Terms and Conditions. Such

security shall be adequate to cover all charges for one Month's advance

service.

(ii) In addition, within thirty (30) Days after such

notification, the Shipper must fully comply with the means for adequate

assurance of future performance, covering three (3) full Months of advance

service from the end of such 30-Day notice period, as provided under this §

10 of these General Terms and Conditions. If the Shipper has not satisfied

the requirements in either of the prior two (2) sentences by the end of the

specified notice period, Overthrust may immediately suspend service to

Shipper. Overthrust may terminate service once it has complied with the

procedures set forth further in this Section below, including the requisite

prior notice.

(iii) If Overthrust does not have sufficient information to

determine whether a Shipper is creditworthy, it may request additional

information in writing from the Shipper consistent with this § 10 of these

General Terms and Conditions, and Shipper must provide such information

within five (5) Business Days. If Shipper fails to provide the requested

information or if Overthrust determines that the Shipper is not creditworthy

based on such information, §10.2(a)(i) of these General Terms and Conditions

shall apply for suspension of service and §10.2(d) shall apply for

termination of service.

(b) Any suspension of service hereunder may continue until

Overthrust is reasonably satisfied that Shipper is creditworthy under this §

10 of these General Terms and Conditions, until Shipper has provided adequate

assurance of future performance under this §10, or until Overthrust

terminates service under §10.2(d) below.
