28. CAPACITY RELEASE (Continued)

28.4 Marketing of Capacity Fee

GTN may act as a facilitator between a Releasing

Shipper and a Replacement Shipper(s) that wishes to contract

for that Releasing Shipper's capacity. All such Parcels must

be posted on the EBB initially. A posting of a Parcel

facilitated by GTN will include both the Parcel by the

Releasing Shipper and the bid by the Prearranged Shipper. A

marketing of capacity fee shall be negotiated between

GTN and Releasing Shipper in a nondiscriminatory

manner. Such a fee will apply when: a Releasing Shipper

requests GTN to market released capacity, GTN

actively markets such capacity beyond posting on the EBB,

and such marketing results in capacity being released to a

Replacement Shipper.

28.5 Posting of a Parcel

The posting of a Parcel constitutes an offer to release the

capacity provided a willing Replacement Shipper submits a

valid bid consistent with GTN's Transportation General

Terms and Conditions. The posting must contain the

information contained in Paragraph 28.3. Any specific

conditions posted by the Releasing Shipper must be

operationally feasible, nondiscriminatory to other shippers,

and in conformance with GTN's tariffs. If the Parcel

is being released as a secondary release, then any recall

provisions included in the primary release which may affect

the re-release of this capacity must be included in the terms

and conditions of the secondary release. Each Parcel will be

reviewed by GTN prior to posting on the Internet website for

bidding. The receipt of a valid release will be acknowledged

by the issuance of a release confirmation to the Releasing

Shipper's e-mail address by GTN.

It is the Releasing Shipper's sole responsibility to provide

release and Prearranged Shipper bid information in advance of

the close of the Posting Period.
