| (3)   | Is it anticipated that any significant change in results of operations from the corresponding period for the last fiscal year will be reflected by the earnings statements to be included in the subject report or portion thereof?           Yes x   No  If so, attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made. In June 2013, the Partnership completed the divestiture of all of its Piceance Basin properties for cash consideration of approximately $174,300.  The net proceeds from this divestiture were distributed pro rata to the Partnership’s partners in July 2013.In December 2013, the Partnership completed the divestiture of all of its remaining oil and gas properties for cash consideration of $206,000.  The net proceeds from this divestiture were retained by the Partnership for payment of Bankruptcy costs or future distribution upon approval of Bankruptcy Court.Recent Developments As discussed above, on February 27, 2014, Schneider Downs resigned as the Partnership’s independent public accounting firm. Given the pending Chapter 11 Proceeding, the Partnership does not intend to appoint a new independent registered public accounting firm at this time. We cannot comment on the results of our operations for the years ended December 31, 2013 and 2012 until the ultimate resolution of the matters discussed above.  |
