GENERAL TERMS AND CONDITIONS

5. PROCEDURES FOR REQUESTING SERVICE (Continued)

(h) Tiebreaker: If more than one bid has the same Bid Value,

capacity will be awarded pro rata among the tying bidders. A bid to pay

the maximum rate as it may vary from time to time for a given term will

be deemed superior to a bid to pay a specified dollar rate which is

equal to the maximum currently effective rate.

(i) Change of Primary Points: In determining the Bid Value of a

request for a change of a Primary Receipt or Delivery Point, the actual

gain or loss in revenue to MRT resulting from such change shall be

considered. Requests to extend the term, increase the Maximum Daily

Quantity, or increase the rates provided under an existing Service

Agreement with MRT shall be considered in determining the Bid Value as a

request for additional service.

(j) Pre-Arranged Deals: MRT may enter into a pre-arranged

service agreement with any party provided that MRT will post the terms

of the pre-arranged transaction and other parties will have an

opportunity to acquire the capacity by submitting a bid for the pre-

arranged capacity which, if awarded, would have a higher incremental

revenue to MRT. Such incremental revenue shall be calculated in

accordance with the criteria set forth above in Section 5.9(e). 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 a bid or combination of bids with a

higher incremental revenue to MRT is submitted, the pre-arranged

Customer will have a one-time right to match the higher bid or

combination of bids in order to obtain the capacity. If the pre-

arranged Customer elects not to match, the capacity will be awarded to

the highest bid or combination of bids which, if accepted, would have a

higher incremental revenue to MRT.
