GENERAL TERMS AND CONDITIONS

5. PROCEDURES FOR REQUESTING SERVICE (Continued)

Notice of such other objective and nondiscriminatory factors that will

be considered shall be posted on MRT's Internet web site at the time MRT posts

notice of available firm capacity under Section 5.9(b). MRT shall not

consider revenues from unrelated services in the determination of incremental

revenues to MRT.

In its analysis, MRT will abide by Commission policy regarding the use

of negotiated rates for purposes of determining the Bid Value of a request

received during an Open Season. MRT shall only consider revenues generated by

the reservation rate and/or guaranteed throughput volumes, proposed by the

Bidder(s). For purposes of its evaluation, MRT will consider the aggregate

of two or more requests for service and award the available capacity to the

request or combination of requests that results in the highest incremental

revenues to MRT.

If the capacity to be allocated to the highest bidder would not result

in awarding all of the available capacity, then MRT, subject to the provisions

herein, will award the remaining capacity to the next highest bidder(s) until

all of the capacity has been awarded or until all valid bids above MRT's

reserve rate have been accepted.

For any capacity awarded pursuant hereto, the successful bidder(s) and

MRT will execute a new service agreement or amendment prior to the

commencement of service which confirms the terms of the accepted bid(s) for

the available capacity.

(f) Posting of Successful Bidders: Upon a determination of the

Successful Bid(s), if any, and in any event, as soon as practicable, but no

later than ten (10) days after the close of the Open Season process and

prior to gas flow, MRT shall post a notice on its Internet web site

identifying the successful bidder(s) and bid(s), if any, along with the Bid

Value analysis employed in determining the successful bid, and shall provide

the actual calculation of the Bid Value with sufficient clarity to permit

bidders to duplicate the results.

(g) Binding Nature of Bids: Bids received during an Open Season

may be withdrawn prior to the end of the posted Open Season period, provided,

however, that a Bidder may not withdraw a bid and resubmit a bid with a lesser

value. Bids that are not withdrawn before the end of the posted Open Season

period are binding.
