                            SECURED CONVERTIBLE NOTE


     FOR  VALUE RECEIVED, U.S. Energy Corp. (the "Maker") a Wyoming corporation,

          payable  at  the  address  of  Payee  or such other place as Payee may

          company  (the  "Maturity  Date").  No advances shall be made by Lender

     4.   Optional  Prepayment.
          --------------------

          A.   Subject  to  paragraph  B  below, from and after the date hereof,
               Maker  shall have the privilege at any time and from time to time
               of  prepaying  this  Note  in  whole  or  in  part  (each,  a
               "Prepayment"),  provided  that Maker shall send a notice (each, a
               "Prepayment Notice") to Payee at least five (5) days prior to the
               date  of  each such prepayment (each, a "Prepayment Date"). There
               shall be no premium or penalty in connection with any Prepayment.
               Each  Prepayment shall be applied first against accrued interest,
               if  any,  and then against principal outstanding. Each Prepayment
               Notice  shall set forth the Prepayment Date and the amount of the
               Prepayment,  specifying  the amount thereof being applied against
               accrued  interest  and  the  amount thereof being applied against
               principal.  The  amount of principal repaid by any Prepayment may
               not  be  re-borrowed.

          B.   In the event that Maker sends a Prepayment Notice to Payee, Payee
               may  elect  prior  to  the Prepayment Date to convert into common
               stock  of  Rocky Mountain Gas, Inc. ("RMG Common Stock") pursuant
               to Section 5 hereof, all or part of the amount of principal to be
               repaid  by  the  proposed  Prepayment  instead  of receiving such
               prepayment.

     5.   Optional Conversion. At any time prior to repayment of all amounts due
          -------------------
          under the Note, all or any portion of the principal amount of the Note
          shall  be  convertible  at the option of the Payee into fully paid and
          non-assessable shares of RMG Common Stock. The number of shares of RMG
          Common  Stock  that Payee shall be entitled to receive upon conversion
          shall be equal to the number attained by dividing the principal amount
          of  the  Note being converted by the Conversion Price. The "Conversion
          Price" shall be equal to the Exercise Price (as defined in the Warrant
          Agreement)  as  of  the  date  of  conversion.

          A.   In order to exercise the conversion privilege, shall give written
               notice of conversion to Maker stating Payee's election to convert
               this  Note  or  the  portion  thereof  in  a  minimum of $100,000
               increments  specified  in said notice. As promptly as practicable
               after  receipt of the notice, Maker shall issue and shall deliver
               to  Payee  a  certificate  or certificates for the number of full
               shares  of  RMG Common Stock issuable upon the conversion of this
               Note  or  portion  thereof  registered  in  the  name of Payee in
               accordance  with  the  provisions  of  this  Section  5.

          B.   Each conversion shall be deemed to have been effected on the date
               the  conversion  notice  shall  have  been  received by Maker, as
               aforesaid,  and Payee shall be deemed to have become on said date
               the  holder of record of the shares of Common Stock issuable upon
               such  conversion.  No  fractional shares of Common Stock shall be
               issued  upon


                                        2
<PAGE>


               conversion  of  this  Note. Any amounts so converted shall not be
               reborrowed.

     6.   Security.  As  security  for  the repayment of all liabilities arising
          --------
          under  this Note, the Maker hereby grants to Payee a security interest
          in and a lien on all of the Collateral (as that term is defined in the
          Pledge  and  Security Agreement). Payee shall have all rights provided
          to  a  secured party under the Pledge and Security Agreement and under
          the  Uniform  Commercial Code of the State of Arizona. The Maker shall
          execute and deliver such documentation as Payee may reasonably request
          to  evidence  and  perfect  Payee's  security interest granted in this
          Section  6.

     7.   Use  of Proceeds. Funds advanced under this Note shall be used for the
          ----------------
          Maker's  and  RMG's  acquisition  and  development  of  natural  gas
          properties  and general corporate purposes consistent with the Maker's
          business  and  that  of  RMG.

     8.   Covenants.  Maker  covenants  and  agrees  that,  so  long  as  any
          ---------
          indebtedness is outstanding hereunder, it will comply with each of the
          following  covenants  (except in any case where Payee has specifically
          consented  otherwise  in  writing):

          C.   Financial  Statements.  Maker  shall  furnish  to Payee quarterly
               ---------------------

               after  notice  thereof to Maker given by Payee, or if an Event of
               Default  shall  occur  under  any  other  Loan  Document;

          C.   Maker:  becomes insolvent, bankrupt or generally fails to pay its
               debts  as  such  debts  become  due;  is adjudicated insolvent or
               bankrupt;  admits  in  writing its inability to pay its debts; or
               shall  suffer  a  custodian,  receiver  or  trustee  for  it  or
               substantially  all  of  its  property  to  be  appointed  and  if

               of  debtors is instituted or commenced by Maker; if any order for
               relief  is  entered relating to any of the foregoing proceedings;

               shall  by  any  act  or  failure  to act indicate its consent to,
