Part  III  -  Narrative

--------------------------------------------------------------------------------

State  below  in  reasonable detail the reasons why Form 10-K, 20-F, 11-K, 10-Q,
N-SAR or the transition report or portion thereof, could not be filed within the
prescribed  time  period.

     From  January 2004 into early May 2004, the Chief Financial Officer of U.S.
Energy Corp. ("USE or the "Company") and his support staff have been required to
devote  extensive  time  to  the  Company's  subsidiary Rocky Mountain Gas, Inc.
taking  over  operations  and  accounting  for  the  coalbed  methane  gas field
purchased  from  Hi-Pro  Production,  LLC  "Hi-Pro")  in  late  January 2004. In
addition,  the  CFO has been required to devote extensive time (including travel
time)  to  working with outside counsel to prepare the Company's reply brief for
filing  with the 10th Circuit Court of Appeals in response to Nukem's appeal, in
the  ongoing  litigation  between  the  Company  and  Nukem.

     These  extraordinary  work  requirements have resulted in the Company being
unable  to  complete the consolidated financial statements for the first quarter
ended March 31, 2004 by the Form 10-Q due date (May 17, 2004, because the formal
due  date  of  May  15,  2004  was  a  Saturday).

     The Company will file the Form 10-Q for first quarter 2004 on or before May
20,  2004  (the  fifth  calendar  day  following  the  May  15,  2004  due date.

notification.

                STEPHEN E. ROUNDS, Special Counsel (303) 377-6997

     (2)  Have  all  other periodic reports required under section 13 or 15(d)of
the  Securities Exchange Act of 1934 or section 30 of the Investment Company Act
of  1940  during  the  preceding  12  months or for such shorter period that the
registrant  was required to file such report(s) been filed? If the answer is no,
identify  reports(s).
                                                               [ X ]Yes   [  ]No

     (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?
                                                               [ X ]Yes   [  ]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.

     As  a result of the acquisition of the Hi-Pro coalbed methane properties in
January  2004, there have been gas sales of $593,400 for the quarter ended March
31,  2004  as compared to gas sales of only $140,000 for the quarter ended March
31,  2003.  Operating expenses associated with the production of coalbed methane
also  increased as a result of the purchase of the Hi-Pro properties. During the
quarter  ended  March 31, 2004, costs and expenses relating to the production of
coalbed  methane  were  $741,400  as  compared to $150,800 for the quarter ended
March  31,  2003.

     During the quarter ended March 31, 2004, the Company recognized $279,200 in
revenues  from  the  sale of Ruby Mining Company stock while no similar revenues
were  recognized  during  the  quarter  ended March 31, 2003. During the quarter
ended  March 31, 2003, the Company recorded non-cash income of $1,615,600 as the
cumulative  effect  of  an accounting change as a result of the adoption of SFAS
143.  No  revenue  recognition as a result of accounting changes was recorded by
the  Company  during  the  quarter  ended  March  31,  2004.
