                               Stock Purchase Agreement

               This  Stock Purchase Agreement ("Agreement") is entered into
          on March __,  1998 at Riverton, Wyoming by (i) U.S. Energy Corp.,
          877  North  8th  West,   Riverton,   Wyoming   82501,  a  Wyoming
          corporation (the "Company"); and (ii) BPI Canadian  Opportunities
          II  Fund,  161  Bay Street, Suite 3900, Toronto, Ontario,  Canada
          M5J, 2S1 (the "Purchaser").

                                       Recitals

               A.   The Company owns, directly and through subsidiaries and
          joint ventures, uranium,  gold  and  other mineral properties and
          uranium processing facilities in the United  States.   Certain of
          these  properties  are  being  developed  for  future  mining and
          processing of gold and uranium.

               B.   In  May  1997,  the Purchaser purchased 171,075 Special
          Purchase Warrants (the "Special  Warrants") issued by Sutter Gold
          Mining  Company,  a  Wyoming  corporation  ("SGMC")  which  is  a
          subsidiary   of   the  Company,  for   a   cash   investment   of
          Cdn$940,912.50.  Each  Special  Warrant  entitled  the  holder to
          acquire from SGMC, at no further cost, one share of Common  Stock
          of  SGMC,  and  one Purchase Warrant; each Purchase Warrant would
          have entitled the holder to purchase one share of Common Stock of
          SGMC, at a price  of  Cdn$6.00  per  whole  share  (the "Purchase
          Warrants"),  during  the  18  months  following  closing  of  the
          offering of the SGMC Special Purchase Warrants.  The offering was
          conducted  pursuant  to  SGMC's  Confidential Offering Memorandum
          ("Memorandum") dated May 5, 1997.

               C.   Pursuant  to  SGMC's  Memorandum   and  the  terms  and
          conditions  of  the  Special Warrants, if SGMC were  to  fail  to
          obtain Prospectus Qualification before the Qualification Deadline
          (as  such  terms  were  defined   in  the  Memorandum)  from  the
          securities   commissions  of  the  Canadian   Provinces   wherein
          purchasers of  the  Special  Warrants  reside, the holders of the
          Special Warrants would be entitled to receive  a Dilution Penalty
          in  the  amount  of  1.1 shares of Common Stock of SGMC  and  1.1
          Purchase Warrants, for  each  Special Warrant exercised after the
          Qualification  Deadline  if  Prospectus  Qualification  were  not
          obtained by the Qualification Deadline.

               D.   The Qualification Deadline has passed as of the date of
          this Agreement, and the Prospectus  Qualification  has  not  been
          obtained  by  SGMC.   The  Purchaser  has not received a Dilution
          Penalty   with  respect  to  the  Special  Warrants   and   their
          constituent securities.

               E.   The  Purchaser  desires  to  diversify and increase its
          original investment by the acquisition of  shares  of  the Common
          Stock of the Company, and the Purchaser has made an offer  to the
          Company  to purchase shares of Common Stock of the Company.   The
          Purchaser and the Company have negotiated the terms of acceptance
          of the offer  by  the  Company.   As  a  result  of the offer and
          subsequent  negotiations  with  the  Purchaser,  the Company  has
          determined to sell shares of Common Stock of the Company  to  the
          Purchaser,  for  the  consideration and on the terms set forth in
          this Agreement.


                                      Agreement

               Now Therefore, in  consideration  of the mutual promises and
          covenants  contained  herein,   and  subject  to  the  terms  and
          conditions of this Agreement, the parties agree as follows:

               1.   Purchase and Sale of Company Shares; Closing Time.

                    (a)  At the closing of this Agreement, the Company will

          US$218,750  in  cash and delivery to the Company of  all  of  the
          171,075 Special Warrants  held  by  the  Purchaser.   As  further
          consideration for the purchase of the shares from the Company, at
          and as of the closing, the Purchaser shall relinquish and forever
          give  up  the  Dilution  Penalty,  and  no  further  document  or
          certificate  concerning  this relinquishment and give up shall be
          necessary.

                    (b)  The Company  is represented in this transaction by
          Dominick  & Dominick Securities,  Inc.  (the  "Placement  Agent")
          pursuant to the terms of the Agency Agreement between the Company
          and the Placement Agent.  The closing of the purchase and sale of
          the shares of the Company will be completed at the offices of the
          Placement Agent  on  or  before  March 31, 1998, or on such other
          date  to which the Company and the  Placement  Agent  agree  (the
          "Closing  Time"),  with  the delivery of (i) the cash and Special
          Warrants  to  the  Company,  duly  endorsed  to  the  Company  or
          accompanied by a stock power with  signature guaranteed, (ii) the
          certificates for the shares of the Company to the Placement Agent
          for transmittal to the Purchaser, and  (iii) a certificate to the

          certificate shall be signed by two officers of the Company, dated
          as of the Closing Time,  certifying on behalf of the Company that
          as of the Closing Time, (x)  all of the Company's representations
          and warranties set forth in paragraph  2.1  of this Agreement are
          true and correct in all material respects; and  (y)  with respect
          to  2.1(i),  except  as  disclosed  in  the public record of  the
          Company as filed with the United States Securities  and  Exchange
          Commission,  there  has  been  no  material adverse change in the
          consolidated financial condition of  the  Company.   Certificates
          for the shares of the Company purchased by the Purchaser shall be
          delivered in the name of the Purchaser, or in such other  name as
          instructed by the Purchaser prior to the Closing Time.

               2    Representations  and Warranties.  Each party represents
          and warrants to the other party as follows:

               2.1  By the Company.  The Company represents and warrants to
          the Purchaser as follows:

                    (a)  (i)  Except   as    disclosed    in   subparagraph
          2.1(a)(i)(x) below, the documents comprising the Company's public
          record  as filed with the United States Securities  and  Exchange
          Commission  pursuant to the United States Securities Exchange Act
          of 1934 contain  an  accurate and complete record of the business
          of the Company.  There has been no material adverse change in the
          business, financial affairs  or  other  condition  of the Company
          that has not been

          publicly disclosed.  The public record does not omit  to disclose
          any  facts relating to the Company which would be material  to  a
          prospective purchaser of its Common Shares.

                              (x)  The  Company's  Form 10-Q Report for the
          fiscal  quarter  ended  November 30, 1997 disclosed  (in  Item  2
          "Management's Discussion  and Analysis of Financial Condition and
          Results of Operations") that  the  $4,000,000  line  item  on the
          balance  sheet  was classified as deferred income, as such amount
          was forfeitable back  to  Kennecott Uranium Company until certain
          conditions were fulfilled.   The  Company  further disclosed that
          the forfeitable terms were satisfied in the  third quarter, which
          would allow such $4,000,000 to be recognized as income during the
          Company's  third  fiscal  quarter  (ended  February   28,  1998).
          Pending further evaluation of the proper accounting treatment  of
          the  Company's  receipt  of  such  $4,000,000,  the  Company  has
          determined  that it may amend the Form 10-Q Report for the fiscal
          quarter ended  November  30,  1997  to  delete  reference  to the
          Company recognizing such $4,000,000 as income.  If the Form  10-Q
          Report is to be amended, such amendment may not be filed with the
          United  States Securities and Exchange Commission until after the
          Closing Time.  However,  for  purposes  of  this  Agreement,  the
          disclosures  in this subparagraph 2.1(a)(i)(x) shall be deemed to
          be part of the  public  record  of  the  Company  as  of the date
          hereof.

                         (ii) The    public   record   (with   respect   to
          information therein which concerns  SGMC)  filed  with the United
          States Securities and Exchange Commission pursuant  to the United
          States Securities Exchange Act of 1934 does not omit  to disclose
          any  non-adverse  facts  which  could be material to a seller  of
          securities of SGMC.

                    (b)  Each of the Company  and its material subsidiaries
          is,  and  will  be  at the Closing Time,  duly  incorporated  and
          organized and validly subsists under the laws of its jurisdiction
          of incorporation (or  other  form  of  organization),  with  full
          corporate  (or  other  entity power) and capacity to carry on its
          business as presently conducted.

                    (c)  Except  as  disclosed  in  the  audited  financial
          statements for the year  ended  May  31,  1997  or  disclosed  in
          writing to the Purchaser, there are no actions, suits, proceeding
          or enquiries threatened or, to the best of its knowledge, pending
          against  or  affecting  the Company or any of its subsidiaries at

          municipal or other  governmental  department,  commission, board,
          bureau or agency which may in any way materially adversely affect
          the business, operations or condition (financial or otherwise) of
          the  Company  or any of its subsidiaries, taken as  a  whole,  or
          which affects or  may  affect  the  sale of Common Stock, and the
          Company  is  not  aware of any existing  grounds  on  which  such
          action, suit, proceeding  or  enquiry might be commenced with any
          reasonable likelihood of success.

                    (d)  The authorized capital  of the Company consists of
          (i) 20,000,000 shares of Common Stock, $.01  par value, of which,

          6,696,474 shares of Common Stock as fully paid and nonassessable,

          telephone  1-800-962-4284,  is  the duly appointed registrar  and
          transfer agent for the shares of Common Stock of the Company.

                    (f)  No regulatory authority  of any other jurisdiction
          has  issued  any order preventing or suspending  trading  in  any
          securities of  the  Company  which  at  the  Closing Time will be
          outstanding, and the Company is not in default of any requirement
          of the securities laws of any province of Canada  or  any laws of
          the  United  States which would reasonably be expected to  affect
          trading in the Company's securities.

                    (g)  The  issued and outstanding shares of Common Stock
          of the Company are quoted on NASDAQ.

                    (i)  The   Company   and  its  subsidiaries   are   the

          statements of the Company for the year ended May 31, 1997 and the
