Item 8.01 - Other Events

On Thursday, January 5, 2006, we signed a Letter of Intent to enter
into a merger agreement with Sunrise Coal, LLC (Sunrise), an Indiana
limited liability limited company.  Sunrise is in the coal business
and currently operates one coal mine and will be opening a second
mine in early 2007.  Both mines are located in southern Indiana.  If
the merger is completed, we will continue our oil and gas operations,
but the majority of our revenue will be from coal operations.

The Letter of Intent as executed by both parties is attached hereto 
as Exhibit 99.1.   As stated in the Letter of Intent, we have agreed
to pay compensation to our affiliate, COALition Energy, LLC (CELLC),
of which we own 29% interest.  See our March 31, 2005 Form 10-QSB
for additional information concerning our investment in CELLC.
