GENERAL TERMS AND CONDITIONS

creditworthy by Overthrust, Shipper may initiate a creditworthiness re-

evaluation by Overthrust. Such re-evaluation shall be performed consistent

with this § 10 of these General Terms and Conditions. As part of Shipper's

re-evaluation request, Shipper must either update or confirm in writing the

prior information provided to Overthrust related to Shipper's

creditworthiness. Such update should include any events that Shipper believes

could lead to a material change in Shipper's creditworthiness. After

Overthrust's receipt of Shipper's request for re-evaluation, including all

required information specified above, within five (5) Business Days,

Overthrust shall provide a written response to Shipper's request. Such

written response should include either a determination of creditworthiness

status, clearly stating the reasons for Overthrust's decision, or an

explanation supporting a future date by which a re-evaluation determination

will be made. In no event should such re-evaluation determination exceed

twenty (20) Business Days from the date of the receipt of Shipper's request

unless specified in this Tariff or if the parties mutually agree to some

later date. If Overthrust determines that Shipper is now creditworthy, any

security required under § 10 of these General Terms and Conditions shall be

terminated and any prepayment amounts (including any applicable interest)

shall be released to Shipper from escrow within five (5) Business Days after

such determination.

(d) In addition to or in lieu of suspension, Overthrust may

terminate service if the Shipper fails to provide adequate assurance of

future performance consistent with this § 10 of these General Terms and

Conditions. Any such termination requires thirty (30) Days' prior notice to

Shipper and to the Commission. Such notice may be given simultaneously with

the notice provided for under § 10.1(b), above. To avoid termination, the

Shipper must satisfy the requirements of § 10.1(b) of these General Terms and

Conditions within this notice period.

(e) Overthrust may not assess reservation charges to a Shipper

for suspended service and a Shipper may not release or recall firm Capacity

under service which has been suspended.

(f) In addition to any prior notice provided for above,

Overthrust shall simultaneously notify the Commission in writing of any

suspension or termination of service under this §10.2.

(g) Overthrust may not take any action under this §10.2 which

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

10.3 In order to obtain an Agreement under Rate Schedule FT, a Shipper

must sign a consent and agreement, in a form acceptable to Overthrust, to pay

all charges under the Agreement to the agent designated by Overthrust's

lenders in the event the Shipper is notified that an event of default has

occurred under Overthrust's loan agreement.
