    4. Withdrawal of Offers to Release and Withdrawal of Bids.  Offers to
Release Capacity and Bids for Released Capacity will be binding until written
or electronic notice of withdrawal is received by MIGC.  Bids can be withdrawn
any time prior to the end of the open season; provided, however that a
Replacement Shipper shall not be able to withdraw a bid in order to submit a
lower bid.  The Releasing Shipper has the right to withdraw its offer during
the open season where unanticipated circumstances justify and no minimum bid
has been made.
   
    5. Best Bid - The "best bid" shall be determined in accordance with the
bid evaluation method specified by the Releasing Shipper pursuant to Section
17.2(a)(8).  The "best bid" must be chosen from the following methodologies and
once chosen will be used in determining the awards from the bid(s) submitted:
(1) the highest rate, (2) the net revenue, or (3) the present value.  In the
event the Releasing Shipper elects not to submit a bid evaluation method, the
"best bid" shall be the bid which generates the maximum net revenue.  If
pursuant to Section 17.2(a) (7) Releasing Shipper states the minimum
Reservation Charge on a percentage basis of the maximum rate, bids shall be
received on a percentage basis of the maximum rate.  In the event both a
contingent bid and a non-contingent bid meet the minimum conditions stated
in 17.2(a) (7) and generate the "best bid," the contingent bid shall be
rejected.
   
    6. Allocation of Released Capacity - MIGC will select the "best bid" as
defined in Section 17.5 from among the bids received.  If more than one bidder
submits the "best bid," the first bidder in time, including the Prearranged
Shipper, will be selected as the best bid, unless the Releasing Shipper
specifies another tie-breaking methodology in its Shipper's Notice.  If
multiple bids meeting minimum conditions have been submitted, bids shall be
awarded, best bid first, until all offered capacity is awarded.  Any bid
submitted may state that its acceptance is contingent provided the Shipper's
Notice allows the submission of contingent bids.  MIGC will allow any
Prearranged Shipper to match, in accordance with Section 17.1, the "best bid"
after the close of the open season.
   
    7. Recalling Released Capacity - Releasing shippers may, to the extent
permitted as a condition of the capacity release, recall released capacity
(scheduled or unscheduled) at any of the daily Nomination cycles, subject to
the specifications in this Section 17.7.  The service flexibility available
to either the Releasing Shipper or the Replacement Shipper(s) for the subject
capacity shall not be less as a result of the recall.  MIGC supports the
ability for the Releasing Shipper to specify, as a condition of a release
capacity offer, which recall notification period(s), as provided in this
Section 17.7, will be available for use by the parties, and whether the
Releasing Shipper's recall notification must be provided exclusively on a
Business Day.  Notice of the allocation of capacity between the Releasing
Shipper and the Replacement Shipper hereunder is intended to be provided in a
