Additional Facilities: Capacity available for subscription as a result of

construction of additional facilities will be posted in accordance with FERC

requirements and/or made available as part of an Open Season.

(b) Posting: Within five days of the date when MRT has determined

that firm capacity is becoming available (for capacity becoming available

under expiring or terminating agreements, MRT will post the availability

within five days of receiving or sending out a termination notice, except in

those cases where the Right of First Refusal process applies and has not been

completed), MRT shall post notice and any updates to such notice on its

Internet web site of available firm capacity in accordance with FERC

regulations, and such notice shall be posted between 8:00 a.m. and 10:00 a.m.

Central Clock Time on regular business days. If firm capacity becomes

available for subscription, such postings shall specify the type of service

that is available, the dates and duration that the service will be available,

the location of the available capacity and/or deliverability, any minimum

terms and conditions that would be acceptable for consideration, any minimum

volumes and/or rates that will be considered, whether capacity turnback will

be accepted for consideration and as an alternative to construction of

incremental facilities, and any other information that MRT determines to be

relevant.

In the event MRT posts notice in an Open Season of minimum bid criteria

which would be acceptable to MRT's allocation of capacity, unless such Open

Season posting is for an expansion of MRT's facilities, MRT shall not be

permitted to change or withdraw the criteria applicable to such minimum bid

during the Open Season, unless no bids meeting such minimum criteria have been

submitted.

Such minimum terms and conditions that MRT may prescribe will include:

Volume; term; rate; segment path, if applicable to a particular posting of

capacity; whether seasonal or only annual capacity subscriptions will be

accepted; whether seasonal or other operational limitations exist relative to

the capacity posted; whether the capacity is only available as a backhaul;

and any applicable operational conditions or limitations affecting the posted

capacity.
