GENERAL TERMS AND CONDITIONS (Continued)

17. FIRM CAPACITY RELEASE MECHANISM (Continued)

17.4 Transporter will determine successful bids for released capacity

and post notification of such successful bids on the Website, along with

the Replacement Shipper's name. Transporter will allow potential

Replacement Shipper(s) to post information concerning requests for firm

capacity that have been received on a Capacity Request Form from

potential Replacement Shipper(s) in accordance with Subsection 17.14

hereof. All requests to acquire firm capacity, excluding the bidder's

name but including the terms and conditions of such request to acquire

firm capacity, will be posted on Transporter's Website in accordance

with Subsection 17.3.

17.4.1 Upon determination by Transporter of the successful bid

in accordance with the procedures set forth in Subsection 17.8,

the process of entering into a contract with the potential

Replacement Shipper will commence.

17.5 There will be two options associated with the Firm Capacity

Release Mechanism: permanent and temporary. Offers should be binding

until written or electronic notice of withdrawal is received by the

capacity release service provider. The releasing party has the right to

withdraw its offer during the bid period, where unanticipated

circumstances justify and no minimum bid has been made. A Releasing

Shipper should not be able to specify an extension of the original bid

period or the pre-arranged deal match period, without posting a new

release. A Releasing Shipper can release capacity at either the monthly

Reservation/Demand rate(s) or the volumetric equivalent of such rate(s).

17.5.1 Releasing Shipper should specify which one of the

following methods is acceptable for bidding on a given capacity

release offer: 1) Non-index-based release - dollars and cents, 2)

Non-index-based release - percentage of maximum rate, or 3) Index-

based formula as detailed in the capacity release offer. The bids

for the given capacity release offer should adhere to the method

specified by the Releasing Shipper. The bidder may bid the

maximum reservation rate, in Transporter's Tariff, as an

alternative to the method specified by the Releasing Shipper,

except when the release is index-based for a term of one year or

less or utilizes market-based rates.
