TRANSPORTATION GENERAL TERMS AND CONDITIONS

28. CAPACITY RELEASE (Continued)

28.6 Bidding for a Parcel (Continued)

(a) Preliminary Qualification (Continued)

Any potential Replacement Shipper may submit a bid for

parcels posted for release. GTN will determine the

highest valued bid, based on the bid evaluation method

selected by the Releasing Shipper, and verify that the

Shipper placing the bid meets GTN's credit

requirements before awarding the parcel. Upon notification

by GTN of an award of a Parcel, GTN shall

complete a new FTS-1 or LFS-1 contract with the particulars

of the awarded Parcel and Replacement Shipper shall execute

this new contract electronically through the use of an

authorization code procedure on the EBB.

Once a Replacement Shipper has acquired capacity, authority

is granted to the Replacement Shipper to release that

capacity, unless the Releasing Shipper has specified that

the Parcel cannot be re-released.

The execution of the FTS-1 or LFS-1 service agreement will

constitute an obligation on the part of the Replacement

Shipper to be bound by the terms and conditions of GTN's

capacity release program as set forth in these

Transportation General Terms and Conditions.

(b) Submitting a Bid

All bids must be submitted through the use of GTN's

EBB. Such bids shall be "open" for all participants to

review. The particulars of all bids will be available for

review but not the identity of bidders. GTN will

post the identity of the winning bidder(s) only.

A Replacement Shipper cannot request that its bid be

"closed", nor can a Releasing Shipper specify that "closed"

bids be submitted on its releases. A Replacement Shipper

may submit only one bid per Parcel posted at any one point

in time. Bids received after the close of the Bid Period

shall be invalid. The Replacement Shipper may bid for no

more than the quantity of the Parcel posted by the

Releasing Shipper. Simultaneous bids for more than one

Parcel are permitted.
