6.3 Qualifications for Bidding. Any party wishing to become a bidding

Shipper must prequalify by satisfying the creditworthiness provisions and

Questline access and signatory requirements of this tariff prior to submitting

a bid for capacity.


6.4 Bid Period. Southern Trails' bid period for firm capacity will

begin on the day available capacity is posted on Questline and will be

administered as described below in CCTs:


(a) The initial bid period will be held from 9:00 a.m. on the

day available capacity is posted on Questline until 1:00 p.m. on the eighth

business day prior to the end of the month. Shippers desiring to submit a bid

for service must do so prior to 1:00 p.m. on the eighth business day prior to

the end of the month. The rate, term and present value of each bid received

during the initial bid period will be shown on Questline as received.

However, the identity of the bidding Shipper shall be kept confidential.


(b) If no competing bids are received for the same available

capacity on Southern Trails' system, the board will close at 1:00 p.m. If

competing bids are received, Southern Trails will post notification of the

competing bids on Questline on or before 2:00 p.m. Shippers who submitted

competing bids will have an opportunity, beginning at 2:00 p.m., to post an

updated bid that equals or exceeds the highest competing bid, as calculated

according to § 6.7. If no bids are received within the first hour, bidding

will close at 3:00 p.m. Otherwise, bidding will continue until there has been

no bidding activity for 30 minutes or until 4:00 p.m., whichever occurs first.


(c) Throughout the bidding period, Southern Trails will continue

posting a list of all bids, including competing bids, on Questline as they are

received or updated.


(d) Except for capacity that is subject to a right of first

refusal according to § 8 of the General Terms and Conditions of this tariff,

capacity will be awarded no later than 11:00 a.m. on the second business day

following the bid period to the Shipper or Shippers whose bid offers a rate

and term that yields the highest present value per unit of capacity and whose

terms and conditions are acceptable to Southern Trails.
