may be acquired through the bidding process described in § 7 of these General

Terms and Conditions.

shall be binding once received by Overthrust and may not be withdrawn by the

bidding Shipper.

(b) The bidding Shipper's bid must include all information

included in § 7 of these General Terms and Conditions.

9.4 Overthrust shall not be obligated to accept any bid for the

capacity at less than the maximum applicable tariff rate or for a term

greater than the term posted in the notice of available unsubscribed

capacity. Upon acceptance of a bid, Overthrust shall inform the existing

Shipper of the terms of the bid to permit Shipper to exercise its right of

first refusal. A Shipper exercising its right of first refusal must match

the highest bid. The existing Shipper shall have five days to inform

Overthrust that it agrees to match the bid.

If the existing Shipper notifies Overthrust that it elects to match the

terms of price and duration of the accepted bid, Overthrust shall contract

with the existing Shipper. If the existing Shipper does not elect to match

the terms of the replacement Shipper's bid, Overthrust will contract with the

replacement Shipper according to the terms and conditions of the tariff.
