(3) Capacity Created as a Result of Constructing

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, MRT shall post

notice and any updates to such notice on its Electronic Bulletin Board

and its designated internet 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.
