(g) whether the bidder is willing to accept

less than the full amount of capacity released in the event

that there are two or more Successful Bidders and Transporter

must pro-rate the capacity in accordance with Section 28.9(c)

below; and

(h) any other terms that may be relevant.

Once a potential Replacement Shipper has submitted a bid,

that bid shall be binding until Transporter receives a written

notice or electronic notice of withdrawal. Once the bidding

period closes, any bid posted on Transporter's Electronic

Bulletin Board shall constitute a binding offer to enter into a

Gas Transportation Contract for Firm Reserved Service, subject

only to the Releasing Shipper's decision to accept a contingent

bid. The bid shall be binding until (i) Transporter selects the

specified award date shall invalidate that bid. A bidder that

withdraws its bid during the bidding period may submit a higher

bid during the bidding period, but may not submit a lower bid.
