FORCE MAJEURE NOTICE


March 24, 2009

Beginning early on Monday, March 23, 2009, Eastern Wyoming began suffering from the 
effects a major winter storm.  The severe nature of this storm has caused road closures 
throughout the area, making it impossible for our field personnel to access facilities.  
Field personnel responsible for the operation of downstream redelivery points have also 
been unable to get to work.  Consequently MIGC LLC (MIGC) is unable to deliver all of 
the contracted firm quantities scheduled from MIGC along its system.   Market cuts are 
being  made by the downstream pipelines and will continue as needed until physical flows 
return to normal.  We appreciate your patience and understanding during this unusual and 
difficult operating.


Pursuant to Section 9 of the Transportation General Terms and Conditions to the FERC Gas 
Tariff, Second Revised Volume No. 1 of MIGC LLC, the severe weather conditions are not 
within the control of MIGC and is a force majeure event affecting MIGC’s ability to 
deliver full contracted firm quantities along the MIGC system under executed Transportation 
Service Agreements.  Shippers whose nominations are affected by this event will be contacted 
regarding the impact to individual shippers.


Sincerely,


Christopher L. Wilson
Commercial Development Regional Manager
