                                U.S. ENERGY CORP.
                             1998 STOCK OPTION PLAN
            As adopted by the Board of Directors on June 15, 1998 and
            constituting a restatement of the 1989 Stock Option Plan,
                which was Amended September 1, 1992, September 3,
                  1993, January 6, 1994, December 22, 1995, and
                               December 13, 1996.

         1. Purpose.  Restrictions on Amount Available Under the Plan. This 1998
Stock  Option Plan (the  "Plan") is intended to  encourage  stock  ownership  by
employees,  consultants and directors of U.S. Energy Corp. (the  "Corporation"),
its divisions and Subsidiary Corporations,  so that they may acquire or increase
their proprietary  interest in the Corporation,  and to encourage such employees
and  directors  to remain  in the  employ  of the  Corporation  and to put forth
maximum  efforts for the success of the  business.  It is further  intended that
options  granted  by the  Committee  pursuant  to  Section 6 of this Plan  shall
constitute  "incentive  stock options"  ("Incentive  Stock Options")  within the
meaning of Section 422A of the Internal Revenue Code of 1986 and the regulations
issued thereunder (the "Code"), and options granted by the Committee pursuant to
Section  7  of  this  Plan  shall   constitute   "nonqualified   stock  options"
("Nonqualified Stock Options").

         2.  Definitions.  As used in this Plan, the following words and phrases
shall have the meanings indicated:

                  (a) "Disability" shall mean an Optionee's  inability to engage
in any  substantial  gainful  activity by reason of any  medically  determinable
physical  or mental  impairment  that can be expected to result in death or that
has lasted or can be expected to last for a  continuous  period of not less than
12 months.

                  (b) "Fair  Market  Value"  per share as of a  particular  date
shall mean the last sale price of the Corporation's  Common Stock as reported on
a national  securities  exchange or on the NASDAQ  National Market System or, if
last sale  reporting  quotation is not  available for the  Corporation's  Common
Stock, the average of the bid and asked prices of the Corporation's Common Stock
as reported by NASDAQ or in the National Quotation Bureau,  Inc.'s "Pink Sheets"
or, if such quotations are  unavailable,  the value  determined by the Committee
(as hereinafter  defined) in accordance  with their  discretion in making a bona
fide, good faith determination of fair market value.

                  (c) "Parent  Corporation"  shall mean any  corporation  (other
than the employer  corporation) in an unbroken chain of corporations ending with
the  employer  corporation  if, at the time of granting  an Option,  each of the
corporations  other than the employer  corporation  owns stock possessing 50% or
more of the total  combined  voting  power of all classes of stock in one of the
other corporations in such chain.

                  (d) "Subsidiary Corporation" shall mean any corporation (other
than the employer  corporation) in an unbroken chain of  corporations  beginning
with the employer corporation if, at the time of granting an Option, each of the
corporations  other than the last  corporation  in the unbroken chain owns stock
possessing  50% or more of the total  combined  voting  power of all  classes of
stock in one of the other corporations in such chain.


                                       106





         3.  Administration.  The Plan shall be administered by a committee (the
"Committee"),  consisting of not less than two members of the Board of Directors
of the  Corporation  (the "Board").  The members of the Committee,  who shall be
selected at a duly convened meeting of the Board of Directors,  shall be persons
who have not been granted or awarded equity  securities of the Corporation under
the Plan or any other plan of the  Employer or its  affiliates,  during the year
prior to awards of securities under the Plan by the Committee.  It is the intent
of this Plan that the Committee members shall be "disinterested  administrators"
as that term is used in Rule  16b-3(c)(2)(i)  promulgated  by the Securities and
Exchange Commission. The members of the Committee shall have all powers, subject
to compliance with the Plan, to select officers and directors for  participation
in the Plan, and to make all decisions concerning the timing, pricing and amount
of a grant or award under the Plan.

         The Committee  shall have the authority in its  discretion,  subject to
and not inconsistent with the express  provisions of the Plan, to administer the
Plan and to exercise all the powers and authorities either specifically  granted
to it under the Plan or  necessary or  advisable  in the  administration  of the
Plan,  including,  without  limitation,  the  authority  to  grant  Options;  to
determine  which  Options  shall  constitute  Incentive  Stock Options and which
Options shall constitute  Nonqualified Stock Options;  to determine the purchase
price of the shares of Common Stock covered by each Option (the "Option Price");
to determine the persons to whom, and the time or times at which,  Options shall
be granted;  to determine the number of shares to be covered by each Option;  to
interpret  the Plan;  to  prescribe,  amend and  rescind  rules and  regulations
relating  to the Plan;  to  determine  the terms and  provisions  of the  Option
Agreements (which need not be identical) entered into in connection with Options
granted under the Plan; and to make all other determinations deemed necessary or
advisable for the  administration of the Plan. The Committee may delegate to one
or more of its members or to one or more agents such administrative duties as it
may deem  advisable,  and the  Committee or any person to whom it has  delegated
duties as aforesaid may employ one or more persons to render advice with respect
to any responsibility the Committee or such person may have under the Plan.

         The Board shall fill all vacancies,  however caused,  in the Committee.
The Board may from time to time appoint additional members to the Committee, and
may at any time remove one or more Committee members and substitute  others. One
member  of the  Committee  shall  be  selected  by the  Board as  chairman.  The
Committee  shall  hold its  meetings  at such  times and places as it shall deem
advisable.  All  determinations  of the Committee shall be made by a majority of
its members either present in person or participating by conference telephone at
a meeting or by written consent.  The Committee may appoint a secretary and make
such rules and  regulations  for the  conduct of its  business  as it shall deem
advisable, and shall keep minutes of its meetings.

         No member  of the Board or  Committee  shall be liable  for any  action
taken or determination made in good faith with respect to the Plan or any Option
granted hereunder.

         4. Eligibility.  Subject to certain limitations  hereinafter set forth,
Options may be granted to employees of (including  officers) and  consultants to
and  directors of (whether or not they are  employees)  the  Corporation  or its
present or future  divisions and Subsidiary  Corporations.  In  determining  the
persons to whom Options  shall be granted and the number of shares to be covered
by each  Option,  the  Committee  shall  take  into  account  the  duties of the
respective persons, their present and potential  contributions to the success of
the  Corporation  and such other factors as the Committee shall deem relevant in
connection  with  accomplishing  the  purpose  of the Plan.  A person to whom an
Option  has been  granted  hereunder  is  sometimes  referred  to  herein  as an
"Optionee."  An Optionee  shall be eligible to receive more than one grant of an
Option  during  the term of the Plan,  but only on the terms and  subject to the
restrictions hereinafter set forth.

         5. Stock. The stock subject to Options hereunder shall be shares of the
Corporation's  Common Stock,  $.01 par value per share  ("Common  Stock").  Such
shares may, in whole or in part,  be  authorized  but unissued  shares or shares
that shall have been or that may be reacquired by the Corporation. The aggregate

                                       107





number of shares of Common Stock as to which Options may be granted from time to
time under the Plan shall not exceed 2,750,000.  The limitations  established by
the  preceding  sentences  shall be subject to adjustment as provided in Section
8(i) hereof.

         In the event that any outstanding  Option under the Plan for any reason
expires or is  terminated  without  having been  exercised in full the shares of
Common Stock  allocable to the  unexercised  portion of such Option  (unless the
Plan shall have been terminated) shall become available for subsequent grants of
options under the Plan.

         6. Incentive Stock Options.  Options granted pursuant to this Section 6
are intended to constitute  Incentive  Stock Options and shall be subject to the
following  special  terms and  conditions,  in addition to the general terms and
conditions specified in Section 8 hereof.  Consultants and directors who are not
employees of the Corporation  shall not be entitled to receive Options  pursuant
to this Section 6.

         The  aggregate  Fair  Market  Value  (determined  as of  the  date  the
Incentive Stock Option is granted) of the shares of Common Stock with respect to
which  Options  are  exercisable  for the first time by an  Optionee  during any
calendar  year may not exceed  $100,000.00.  If more than  $100,000 of shares is
subject to Options  held by an  Optionee,  the  Corporation  shall cause  (A)the
maximum number of Options to be designated ISOs and the balance to be designated
nonqualified stock options;  or (B) different share certificates to be issued on
first exercise,  such that one certificate  shall be issued for the shares which
are  issued  under the ISOs,  and  another  certificate  shall be issued for the
nonqualified stock options.

         Incentive Stock Options granted under this Plan are intended to satisfy
all requirements for incentive stock options under the Code and, notwithstanding
any other  provision  of this Plan,  the Plan and all  Incentive  Stock  Options
granted under it shall be so construed,  and all contrary provisions shall be so
limited in scope and effect and,  to the extent they cannot be so limited,  they
shall be void.

         7. Nonqualified Stock Options. Options granted pursuant to this Section
7 are intended to  constitute  Nonqualified  Stock  Options and shall be subject
only to the general terms and conditions specified in Section 8 hereof.

         8. Terms and Conditions of Options. Each Option granted pursuant to the
Plan shall be evidenced by a written Option  Agreement  between the  Corporation
and the  Optionee,  which  agreement  shall  comply  with and be  subject to the
following terms and conditions:

                  (a) Number of Shares.  Each Option  Agreement  shall state the
number of shares of Common Stock to which the Option relates.

                  (b) Type of Option.  Each Option Agreement shall  specifically
identify the portion, if any, of the Option which constitutes an Incentive Stock
Option and the portion, if any, which constitutes a Nonqualified Stock Option.

                  (c) Option Price. Each Option Agreement shall state the Option
Price,  which shall be not less than 100% of the Fair Market Value of the shares
of Common  Stock of the  Corporation  on the date of grant of the Option  except
that any option  granted under the Plan to a person owning more than ten percent
of the total  combined  voting  power of the Common Stock shall be at a price of
110% of such  fair  market  value  and  shall be for a term of no more than five
years, in the case of Incentive Stock Options, and not less than 80% of the Fair
Market  Value of the shares of Common  Stock of the  Corporation  on the date of
grant of the  Option in the case of Non-  Qualified  Stock  Options.  The Option
Price shall be subject to  adjustment  as provided in Section 8(i)  hereof.  The
date on which the  Committee  adopts a resolution  expressly  granting an Option
shall be considered the day on which such Option is granted.

                                       108





                  (d) Method of Exercise  and Medium and Time of  Payment.  Each
exercise of an Option granted  hereunder,  whether in whole or in part, shall be
by written notice to the Secretary of the Corporation  designating the number of
shares as to which the Option is exercised,  and shall be accompanied by payment
in full of the  Option  Price (in cash,  shares or  property)  for the number of
shares so  designated,  together  with any  written  statements  required by any
applicable securities laws. The Option Price shall be paid in cash, in shares of
Common  Stock  having  a Fair  Market  Value  equal to such  Option  Price or in
property or in a combination of cash,  shares and property,  and may be effected
in whole or in part (i) with monies received from the Corporation at the time of
exercise as a compensatory  cash payment,  or (ii) with monies borrowed from the
Corporation  pursuant to repayment  terms and  conditions as shall be determined
from time to time by the Committee,  in its discretion,  separately with respect
to each exercise of Options and each Optionee; provided, however, that each such
method and time for payment and each such  borrowing and terms and conditions of
repayment  shall be permitted by and be in compliance  with  applicable law. The
Board of  Directors  shall have the sole and  absolute  discretion  to determine
whether or not property  other than cash or Common Stock may be used to purchase
the shares of Common Stock  hereunder  and, if so, to determine the value of the
property received.

                  (e) Term and Exercise of Options. Options shall be exercisable
over the exercise  period as and at the times the  Committee may  determine,  as
reflected in the Option Agreement;  provided,  however, that the Committee shall
have the authority to accelerate the exercisability of any outstanding Option at
such time and under  such  circumstances  as it, in its sole  discretion,  deems
appropriate. The exercise period shall be determined by the Committee; provided,
however,  that such exercise  period shall not exceed ten years from the date of
grant of the Option. The exercise period shall be subject to earlier termination
as provided in Sections 8(f) and 8(g) hereof. An Option may be exercised,  as to
any or all full  shares  of  Common  Stock as to which  the  Option  has  become
exercisable;  provided,  however, that an Option may not be exercised at any one
time as to fewer  than 100  shares  (or such  number  of  shares as to which the
Option is then exercisable if such number of shares is less than 100).

                  (f)  Termination.  Except as provided in this Section 8(f) and
in Section  8(g) hereof,  an Option may not be exercised  unless the Optionee is
then an employee or director of or consultant to the  Corporation  or a division
or Subsidiary  Corporation  thereof (or a corporation  or a Parent or Subsidiary
Corporation of such corporation  issuing or assuming the option in a transaction
to which  Section  425(a) of the Code  applies),  and  unless the  Optionee  has
remained  continuously  as an  employee  or  director  of or  consultant  to the
Corporation  since  the date of  grant  of the  Option.  In the  event  that the
Optionee  ceases  to  be  an  employee  or  director  of or  consultant  to  the
Corporation  (other  than by reason of death,  Disability  or  retirement),  all
Options of such Optionee that are exercisable at the time of such cessation may,
unless earlier  terminated in accordance with their terms,  be exercised  within
three months after such cessation;  provided, however, that if the employment or
consulting  relationship of an Optionee shall terminate,  or if a director shall
be removed,  for cause, all Options  theretofore granted to such Optionee shall,
to the extent not theretofore  exercised,  terminate  forthwith.  Nothing in the
Plan or in any Option  granted  pursuant  hereto shall confer upon an individual
any right to continue in the employ of the  Corporation  or any of its divisions
or  Subsidiary  Corporations  or  interfere  in any way  with  the  right of the
Corporation or its  shareholders or any such division or Subsidiary  Corporation
to terminate such  employment or other  relationship  between the individual and
the Corporation or any of its divisions and subsidiary corporations.

                  (g) Death Disability or Retirement of Optionee. If an Optionee
shall  die while a  director  of,  or  employed  by,  or a  consultant  to,  the
Corporation or a Subsidiary  Corporation  thereof,  or within three months after
the  termination of such  Optionee's  employment or  directorship  or consulting
relationship,  other than termination for cause, or if the Optionee's employment
or  directorship  or  consulting  relationship,  shall  terminate  by  reason of
disability  or  retirement,  all Options  theretofore  granted to such  Optionee
(whether  or not  otherwise  exercisable)  may,  unless  earlier  terminated  in
accordance  with their terms,  be exercised by the Optionee or by the Optionee's
estate or by a person who acquired the right to exercise such Option by bequest

                                       109





or  inheritance  or  otherwise  by  reason  of the  death or  Disability  of the
Optionee,  at any time  within one year after the date of death,  Disability  or
retirement of the Optionee.

                  (h)  Nontransferability.  Options granted under the Plan shall
not  be  transferable  other  than  by  will  or by  the  laws  of  descent  and
distribution, and Options may be exercised, during the lifetime of the Optionee,
only by the Optionee or by his guardian or legal representative.

                  Any attempted sale, pledge, assignment, hypothecation or other
transfer  of an option  contrary  to the  provisions  hereof and the levy of any
execution,  attachment or similar  process upon an option shall be null and void
and without force or effect.

                  As a condition  to the  transfer of any shares of Common Stock
issued  under this Plan,  the  Corporation  may  require an opinion of  counsel,
satisfactory to the Corporation, to the effect that such transfer will not be in
violation of the Securities Act of 1933 or any other applicable  securities laws
or that such transfer has been registered under federal and all applicable state
securities laws.  Further,  the Corporation  shall be authorized to refrain from
delivering or  transferring  shares of Common Stock issued under this Plan until
the Board of  Directors  determines  that such  delivery  or  transfer  will not
violate  applicable  securities  laws  and  the  Optionee  has  tendered  to the
Corporation any federal,  state or local tax owed by the Optionee as a result of
exercising the Option,  or disposing of any Common Stock,  when the  Corporation
has a legal liability to satisfy such tax. The  Corporation  shall not be liable
for  damages due to delay in the  delivery or issuance of any stock  certificate
for any reason  whatsoever,  including,  but not limited  to, a delay  caused by
listing requirements of any securities exchange or any registration requirements
under the Securities Act of 1933, the Securities  Exchange Act of 1934, or under
any other state or federal law, rule or regulation.  The Corporation is under no
obligation  to take any  action or incur any  expense  in order to  register  or
qualify the  delivery or  transfer  of shares of Common  Stock under  applicable
securities  laws  or  to  perfect  any  exemption  from  such   registration  or
qualification.  Furthermore,  the  Corporation  will  have no  liability  to any
Optionee  for  refusing  to deliver or transfer  shares of Common  Stock if such
refusal is based upon the foregoing provisions of this Paragraph.

                  (i)      Effect of Certain Changes.

                            (1) If there is any  change in the  number of shares
      of Common Stock through the  declaration  of stock  dividends,  or through
      recapitalization  resulting in stock splits,  or combinations or exchanges
      of such  shares,  the  number  of shares of  Common  Stock  available  for
      Options, the number of such shares covered by outstanding Options, and the
      price per share of such Options, shall be proportionately  adjusted by the
      Committee  to reflect  any  increase  or  decrease in the number of issued
      shares of Common Stock;  provided,  however,  that any  fractional  shares
      resulting from such adjustment shall be eliminated.

                            (2) In the  event  of the  proposed  dissolution  or
      liquidation of the Corporation,  in the event of any corporate  separation
      or  division,  including,  but not  limited  to,  split-up,  split-off  or
      spin-off,  or in the event of a merger or consolidation of the Corporation
      with another  corporation,  the  Committee  may provide that the holder of
      each Option then exercisable  shall have the right to exercise such Option
      (at its then  Option  Price)  solely  for the kind and amount of shares of
      stock and other  securities,  property,  cash or any  combination  thereof
      receivable upon such dissolution,  liquidation, or corporate separation or
      division,  or merger or  consolidation by a holder of the number of shares
      of  Common  Stock  for  which  such  Option  might  have  been   exercised
      immediately   prior  to  such  dissolution,   liquidation,   or  corporate
      separation  or division,  merger or  consolidation;  or the  Committee may
      provide, in the alternative, that each Option granted under the Plan shall
      terminate as of a date to be fixed by the  Committee;  provided,  however,
      that not less than 30 days'  written  notice of the date so fixed shall be
      given to each Optionee,  who shall have the right, during the period of 30
      days preceding such termination,  to exercise the Options as to all or any
      part of the shares of Common Stock covered thereby, including shares as to
      which such Options would not otherwise be exercisable.

                                       110





                            (3)  Paragraph  (2) of this  Section  8(i) shall not
      apply  to a  merger  or  consolidation  in which  the  Corporation  is the
      surviving corporation and shares of Common Stock are not converted into or
      exchanged  for stock,  securities  of any other  corporation,  cash or any
      other thing of value.  Notwithstanding the preceding sentence,  in case of
      any consolidation or merger of another corporation into the Corporation in
      which the Corporation is the surviving corporation and in which there is a
      reclassification  or change  (including  a change to the right to  receive
      cash or other property) of the shares of Common Stock (other than a change
      in par  value,  or from par  value to no par  value,  or as a result  of a
      subdivision or  combination,  but including any change in such shares into
      two or more classes or series of shares),  the  Committee may provide that
      the  holder  of each  Option  then  exercisable  shall  have the  right to
      exercise such Option solely for the kind and amount of shares of stock and
      other securities  (including those of any new direct or indirect parent of
      the Corporation),  property,  cash or any combination  thereof  receivable
      upon such reclassification,  change, consolidation or merger by the holder
      of the number of shares of Common  Stock for which such Option  might have
      been exercised.

                            (4) In the event of a change in the Common  Stock of
      the Corporation as presently constituted,  which is limited to a change of
      all of its authorized shares with par value into the same number of shares
      with a different par value or without par value, the shares resulting from
      any such change  shall be deemed to be the Common Stock within the meaning
      of the Plan.

                            (5) To the  extent  that the  foregoing  adjustments
      relate to stock or securities of the Corporation,  such adjustments  shall
      be made by the  Committee,  whose  determination  in that respect shall be
      final,  binding and conclusive,  provided that each Incentive Stock Option
      granted  pursuant  to this Plan  shall not be  adjusted  in a manner  that
      causes such option to fail to  continue to qualify as an  Incentive  Stock
      Option within the meaning of Section 422A of the Code.

                            (6) Except as  hereinbefore  expressly  provided  in
      this Section  8(i),  this  Optionee  shall have no rights by reason of any
      subdivision  or  consolidation  of  shares  of stock  of any  class or the
      payment of any stock  dividend  or any other  increase  or decrease in the
      number of  shares  of stock of any class or by reason of any  dissolution,
      liquidation,  merger,  or consolidation or spin- off of assets or stock of
      another  corporation;  and any issue by the Corporation of shares of stock
      of any class, or securities convertible into shares of stock of any class,
      shall not affect,  and no adjustment by reason  thereof shall be made with
      respect to, the number or price of shares of Common  Stock  subject to the
      Option.  The grant of an Option  pursuant  to the Plan shall not affect in
      any way  the  right  or  power  of the  Corporation  to make  adjustments,
      reclassifications,  reorganizations  or changes of its capital or business
      structures  or to merge or to  consolidate  or to  dissolve,  liquidate or
      sell, or transfer all or part of its business or assets.

                  (j) Rights as Shareholder - Non-Distributive Intent. Neither a
person to whom an Option is granted,  nor such  person's  legal  representative,
heir,  legatee or  distributee,  shall be deemed to be the holder of, or to have
any rights of a holder with respect to, any shares subject to such Option, until
after the Option is exercised and the shares are issued to the person exercising
such Options. Upon exercise of an Option at a time when there is no registration
statement  in effect  under the  Securities  Act of 1933  relating to the shares
issuable upon  exercise and  available for delivery of a prospectus  meeting the
requirements  of  Section  10(a)(3)  of said  Act,  shares  may be issued to the
Optionee  only  if the  Optionee  represents  and  warrants  in  writing  to the
Corporation  that the shares purchased are being acquired for investment and not
with a view to the  distribution  thereof.  No shares  shall be issued  upon the
exercise of an Option unless and until there shall have been compliance with any
then applicable  requirements of the Securities and Exchange Commission,  or any
other  regulatory  agencies  having   jurisdiction  over  the  Corporation.   No
adjustment shall be made for dividends  (ordinary or  extraordinary,  whether in
cash,  securities or other  property) or  distribution or other rights for which
the record date is prior to the date such stock certificate is issued, except as
provided in Section 8(i) hereof.


                                       111





                  (k) Other Provisions.  The Option Agreements  authorized under
the Plan shall contain such other provisions, including, without limitation, (i)
the imposition of restrictions  upon the exercise of an Option,  and (ii) in the
case  of  an  Incentive  Stock  Option,  the  inclusion  of  any  condition  not
inconsistent  with such Option  qualifying as an Incentive Stock Option,  as the
Committee shall deem advisable.

                  (l)  Forfeiture   Provisions:   All  shares  of  Common  Stock
purchased on exercise of all Nonqualified Options granted after the date of this
Plan  Amendment  (and all shares of Common  Stock  purchased  on exercise of all
Nonqualified  Options  granted  prior to such  date  provided  that  the  holder
consents),  shall be subject to forfeiture  back to the Corporation in the event
of termination of employee,  director or consultant  status with the Corporation
on or before January 5 of the second calendar year after exercise.  For example,
Common  Stock  purchased  on  September  1, 1993 by exercise  of a  Nonqualified
Option,  will be subject to forfeiture through January 5, 1995.  Provided,  that
upon exercise of a  Nonqualified  Option at a time when there is a  registration
statement  in effect  under the  Securities  Act of 1933  relating to the shares
issuable upon exercise,  the preceding  forfeiture  provisions of this paragraph
shall immediately terminate.

         9. Agreement by Optionee Regarding  Withholding Taxes. If the Committee
shall so require, as a condition of exercise, each Optionee shall agree that:

                  (a) No later than the date of exercise  of any Option  granted
hereunder,  the  Optionee  will  pay to the  Corporation  or  make  arrangements
satisfactory to the Committee  regarding payment of any federal,  state or local
taxes of any kind  required  by law to be  withheld  upon the  exercise  of such
Option; and

                  (b) The Corporation shall, to the extent permitted or required
by law,  have the right to  deduct  federal,  state and local  taxes of any kind
required by law to be withheld upon the exercise of such Option from any payment
of any kind otherwise due to the Optionee.

                  The Corporation  shall not be obligated to advise any Optionee
of the existence of any such tax or the amount which the Corporation  will be so
required to withhold.

         10. Term of Plan. Options may be granted pursuant to the Plan from time
to time  within a period of ten years  from the date the Plan is  adopted by the
Board, or the date the Plan is approved by the  shareholders of the Corporation,
whichever is earlier.

         11.  Amendment and  Termination  of the Plan. The Board at any time and
from time to time may suspend,  terminate,  modify or amend the Plan;  provided,
however,  that any amendment that would materially increase the aggregate number
of shares of Common Stock as to which  Options may be granted  under the Plan or
materially  increase the  benefits  accruing to  participants  under the Plan or
materially  modify the  requirements as to eligibility for  participation in the
Plan shall be subject to the approval of the holders of a majority of the Common
Stock issued and outstanding, except that any such increase or modification that
may result from adjustments  authorized by Section 8(i) hereof shall not require
such  approval.   Except  as  provided  in  Section  8  hereof,  no  suspension,
termination,  modification  or  amendment of the Plan may  adversely  affect any
Option  previously  granted,  unless  the  written  consent of the  Optionee  is
obtained.

         12.  Approval  of  Shareholders.  The Plan shall take  effect  upon its
adoption  by the Board but shall be subject to the  approval of the holders of a
majority  of  the  issued  and  outstanding   shares  of  Common  Stock  of  the
Corporation,  which approval must occur within 12 months after the date the Plan
is adopted by the Board.

         13.  Assumption.  The terms and conditions of any  outstanding  Options
granted  pursuant to this Plan shall be assumed by, be binding upon and inure to
the benefit of any successor corporation to the

                                       112





Corporation and shall continue to be governed by, to the extent applicable,  the
terms  and  conditions  of this  Plan.  Such  successor  corporation  shall  not
otherwise be obligated to assume this Plan.

         14.  Termination of Right of Action.  Every right of action arising out
of or in connection  with the Plan by or on behalf of the  Corporation or of any
Subsidiary,  or by any  shareholder  of  the  Corporation  or of any  Subsidiary
against  any  past,  present  or future  member of the  Board,  or  against  any
employee, or by an employee (past, present or future) against the Corporation or
any Subsidiary,  will,  irrespective of the place where an action may be brought
and irrespective of the place of residence of any such shareholder,  director or
employee,  cease and be barred by the expiration of three years from the date of
the act or  omission in respect of which such right of action is alleged to have
risen.

         15. Tax Litigation.  The Corporation  shall have the right, but not the
obligation,   to  contest,   at  its  expense,   any  tax  ruling  or  decision,
administrative or judicial,  on any issue which is related to the Plan and which
the Board  believes to be important to holders of Options  issued under the Plan
and to conduct any such contest or any litigation  arising  therefrom to a final
decision.

         IN WITNESS WHEREOF, the foregoing is the 1998 Stock Option Plan of U.S.
Energy  Corp.,  as amended at September 1, 1992,  September 3, 1993,  January 6,
1994,  December 22, 1995, December 13, 1996 and June 15, 1998, and as such, this
1998 Stock Option Plan  constitutes a restatement of the 1989 Stock Option Plan.
This 1998  Stock  Option  Plan is to be  submitted  to the  shareholders  of the
Corporation for approval at the 1998 Annual Meeting of Shareholders.

         NOW, THEREFORE,  in consideration of the premises, the mutual covenants
herein set forth and other good and valuable consideration,  the Corporation and
the Optionee agree as follows:
         1. Confirmation of Grant of Option.  Pursuant to a determination of the
Directors of the Corporation  (the "Board") on __________,  ______,  _______ the
Corporation,  subject to the terms of the Plan and of this  Agreement,  confirms

"Date of  Grant"),  as a matter of separate  inducement  and  agreement,  and in
addition  to and not in lieu of salary or other  compensation  for  services,  a
(Qualified) (Non-Qualified) Stock Option pursuant to Section _______ of the Plan
(the "Option") to purchase an aggregate of ___________ shares of Common Stock on
the terms and  conditions  herein set forth subject to adjustment as provided in

adjustment as provided in Section 8 hereof.
         3. Exercise of Option. Except as otherwise provided in Section 8 of the
Plan,  the Option may be  exercised in whole or part at any time during the term
of the Option,  provided,  however,  no Option  shall be  exercisable  after the
expiration of the term thereof,  and no Option shall be  exercisable  unless the
holder  shall at the time of exercise  have been an employee or director of or a
consultant to the  corporation  or of any  subsidiary of the  Corporation  for a
period of at least three  months.  The Option may be exercised  only as to whole
shares in increments of 100 shares.
         The Option may be  exercised,  as provided in this Section 3, by notice
and payment to the Corporation as provided in Section 10 hereof and Section 8(d)
of the Plan.
         4.  Term  of  Option.   The  term  of  the   Option   will  be  through
______________,  _____,  subject  to  earlier  termination  or  cancellation  as
provided in this  Agreement.  Except as otherwise  provided in Section 7 hereof,

includes each "subsidiary corporation" as defined in the Plan.
         The holder of the Option will not have any rights to  dividends  or any
other rights of a shareholder with respect to any shares of Common Stock subject

purchase of such shares through exercise of the Option.
         5.  Nontransferability  of  Option.  The  Option  may not be  assigned,
transferred  (except as provided in the next  preceding  sentence)  or otherwise
disposed of, or pledged or  hypothecated in any way (whether by operation of law
or otherwise)  otherwise  than by will or the laws of descent and  distribution,
and shall  not be  subject  to  execution,  attachment,  or other  process.  Any
assignment,  transfer, pledge,  hypothecation or other disposition of the Option
or any attempt to make any such levy of  execution,  attachment or other process
will cause the Option to terminate  immediately  upon the  happening of any such
event,  provided,  however,  that any such  termination  of the Option under the
foregoing provisions of this Section 5 will not prejudice any rights or remedies
with  the  Corporation  or any  subsidiary  may have  under  this  Agreement  or
otherwise.
         6. Exercise Upon  Termination.  The Optionee's  rights to exercise this
Option upon  termination  of employment or cessation as a director or consultant

occurrence of certain events as set forth in Section 8(i) of the Plan.

nor the shares of Common Stock  subject  thereto and issuable  upon the exercise
thereof  are  registered  under the  Securities  Act of 1933,  as  amended.  The
Optionee  represents  that the  Option  is being  acquired  by him and that such

         shares  may not be  offered  for sale,  sold or  otherwise  transferred
         except pursuant to an effective  registration  statement under the Act,
         the  availability of which is to be established to the  satisfaction of
         the Company.

         10. Notices.  Each notice relating to this Agreement will be in writing
and delivered in person or by certified mail to the proper address.  All notices

         11.  Approval of Counsel.  The  exercise of the Option and the issuance
and  delivery of shares of Common  Stock  pursuant  thereto  shall be subject to
approval  by the  Corporations'  counsel  of all  legal  matters  in  connection
therewith,  including  compliance with the requirements of the Securities Act of
1933, as amended,  the Securities  Exchange Act of 1934, as amended,  applicable
state   securities  laws,  the  rules  and  regulations   thereunder,   and  the
requirements  of any stock  exchange  upon  which the  Common  Stock may then be
listed.
         12. Benefits of Agreement.  This Agreement will inure to the benefit of
and be binding upon each  successor and assign of the Company.  All  obligations
imposed upon the Optionee and all rights granted to the  Corporation  under this
Agreement will be binding upon the Optionee's heirs, legal  representatives  and

the  Corporation's  obligation  to sell and deliver  shares upon the exercise of
rights to purchase  shares is subject to all applicable  federal and state laws,

incorporated  herein by  reference.  In the  event  that any  provision  in this
Agreement conflicts with a provision in the Plan, the Plan shall govern.

executed in its name by its President or a Vice  President and it corporate seal
to be hereunto affixed and attested by its Secretary or its Assistant  Secretary
