                               SUMMARY INFORMATION

     The following summarizes all material information found elsewhere in this
prospectus and the information incorporated into it by reference. This summary
is qualified by the more detailed information in this prospectus and the
information incorporated by reference.

THE COMPANY

     U.S. Energy Corp. is a Wyoming corporation, formed in 1966, in the business
of acquiring, exploring, developing and/or selling or leasing mineral
properties, and the mining and marketing of minerals. We now are engaged in the
exploration of coalbed methane gas properties, which is our primary business
focus. The only activities of a significant and recurring nature are in coalbed
methane.

     We also hold mining properties, but these properties (uranium and a
property in Sutter Creek, California we bought for gold exploration) are shut
down. The most significant uranium properties are located on Sheep Mountain in
Wyoming and in southeast Utah. We also hold a royalty interest in claims on
Green Mountain, Wyoming, now held by Kennecott Uranium Company (see below).
Interests are held in other mineral properties (principally molybdenum), but are
either non-operating interests or undeveloped claims. We also hold commercial
properties, most of which are located in Utah and leased to third parties. Our
fiscal year ends May 31 but on December 16, 2002, our Board of Directors adopted
a resolution changing the fiscal year end of USE and its affiliates to December
31, effective December 31, 2002.

     The exploration of coalbed methane properties is conducted through Rocky
Mountain Gas, Inc. RMG, a Wyoming corporation, is owned 51.1% by USE and 40.4%
by Crested Corp. Crested is a 70.5% majority-owned subsidiary of the company
(see below). Properties of RMG are held in southeastern Montana, and
northeastern and southwestern Wyoming. In April 2002, a lawsuit was filed
challenging the validity of Bureau of Land Management leases in Montana.
Approximately 32% (88,411 acres) of RMG's total acreage is leased from the BLM
in Montana. See Item 3 (Legal Proceedings) in the Form 10-K/A for fiscal 2002.
The status of this litigation will be updated in subsequent SEC filings.

     Except for the Bobcat Field (for which we have established gas reserves) we
don't know if anything of value will result from our activities in the coalbed
methane area: Only a limited number of exploratory wells have been drilled, and
there is not yet enough information from these wells to determine if they
contain proved reserves; gas prices are low in the Powder River Basin (our area
of activity); permitting issues may delay further work, and more funding may be
needed but not available.

     USE and Crested originally were independent companies, with two common
affiliates (John L. Larsen and Max T. Evans, Mr. Evans is now deceased). In
1980, USE and Crested formed a joint venture, referred to as the USECC Joint
Venture, to do business together (unless one or the other elected not to pursue
an individual project). As a result of USE funding certain of Crested's
obligations from time to time (due to Crested's lack of cash on hand), and later
payment of debts by Crested issuing common stock to USE, Crested became a
majority-owned subsidiary of USE in fiscal 1993. In fiscal 2001, Crested issued
another 6,666,666 shares of common stock to reduce Crested's debt owed to USE by
$3.0 million, which increased USE's ownership of Crested to 70.5%.


                                        4





     All of USE's (and Crested's) operations are in the United States. Principal
executive offices for USE are located in the Glen L. Larsen building at 877
North 8th Street West, Riverton, Wyoming 82501, telephone 307.856.9271; fax
307.857.3050.

     Most of the company's (USE's) operations are conducted through
subsidiaries, the USECC joint venture with Crested, and various jointly-owned
subsidiaries of USE and Crested.

     Until September 11, 2000, USE and Kennecott Uranium Company ("Kennecott"),
owned the Green Mountain Mining Venture ("GMMV"), which held a large uranium
deposit and uranium mill in Wyoming. On September 11, 2000, USE and Crested
settled litigation with Kennecott involving the GMMV by selling their interest
in the GMMV and its properties back to Kennecott for $3.25 million and receiving
a royalty interest in the uranium properties. Kennecott also assumed all
reclamation obligations on the GMMV properties. Other principal uranium
properties and an uranium mill in southeast Utah are held by Plateau Resources
Ltd., a wholly-owned subsidiary of USE. The Utah uranium properties are shut
down.

     The gold property held by Sutter Gold Mining Company ("SGMC"), a
majority-owned subsidiary of USE, is shut down so far as a prospective mining
operation is concerned, because the current price of gold is too low to raise
the capital necessary to put the properties into production. There are no
current plans to start mining activities at Sutter.

GAS RESERVES FOR BOBCAT FIELD

     The following table sets forth estimated proved reserves of gas and the
present value (discounted 10%, referred to as the "PV10") of such reserves as of
December 31, 2002. These reserves are for the Bobcat Field (24 wells, all
producing from the Cook coal, and wells to be drilled to the Cook coal, on
acreage adjacent to the producing wells). The reserve data and the present value
as of that date were prepared by Ryder Scott Company, independent petroleum
engineers. For further information, see Ryder Scott's reserve report included as
an exhibit to registration statement covering this prospectus.

     Refer to these definitions when reading the reserve information:

     PROVED RESERVES: The estimated quantities of gas that geological and
engineering data demonstrate with reasonable certainty to be recoverable in
future years from known reservoirs under existing economic and operating
conditions.

     PROVED DEVELOPED RESERVES: Proved reserves that can be expected to be
recovered from existing wells with existing equipment and operating methods.

     PROVED UNDEVELOPED RESERVES: Proved reserves that are expected to be
recovered from new wells on undrilled acreage.

     PRESENT VALUE (also referred to below as the "PV10 VALUE"): The present
value of estimated future revenues to be generated from the production of proved
reserves, net of estimated production and future development costs, using prices
and costs as of the calculation date without future escalation, all without
giving effect to non-property related expenses (such as general and
administrative expenses, debt service, or future income tax expense), or to
depreciation, depletion and amortization, and discounted using an annual
discount rate of 10%.

     The PV10 value was prepared using constant prices ($3.00 per Mcf) as of the
calculation date, discounted at 10% per annum on a pre-income tax basis, and is
not intended to represent the current market value of the estimated gas reserves
owned by the company. Note that the PV10 discount factor has been calculated net
of ad valorem and production taxes, but before income taxes. The PV10 discount
factor is not the same as the standardized measure of present value calculations
which are determined on an after-income tax basis.

                               Proved Reserves     Proved Reserves
                               ---------------     ---------------
                                  Developed          Undeveloped       Total

Coalbed methane gas (Mmcf)           489.7                  95.9           585.6
PV10 Value                       $ 793,482             $  94,947       $ 888,429

     These estimates of proved reserves have been filed only with the Securities
and Exchange Commission, and have not been included in reports to other federal
agencies.

     Note that there are numerous uncertainties inherent in estimating gas
reserves and their estimated values, including many factors beyond the control
of the company. Reservoir engineering is a subjective process of estimating
underground accumulations of gas that cannot be measured exactly. Estimates of
economically recoverable gas, and the future net cash flows which may be
realized from the reserves,

                                        6





necessarily depend on a number of variable factors and assumptions, such as
historical production from the area compared with production from other areas,
the assumed effects of regulations by government agencies, assumptions about
future gas prices and operating costs, severance and excise taxes, development
costs, and workover and remedial costs. The outcomes in fact may vary
considerable from the assumptions.

     Estimates of the economically recoverable quantities of gas attributable to
any particular property, the classification of reserves as to proved developed
and proved undeveloped based on risk of recovery, and estimates of the future
net cash flows expected from the properties, as prepared by different engineers
or by the same engineers but at different times, may vary substantially, and the
estimates may be revised up or down as assumptions change.

     It is likely that actual production volumes, revenues from production, and
the amount of money spent on a property's reserves, will vary from the
estimates. These variances could be material.

     The PV10 discount factor, which is required by Securities and Exchange
Commission for use in calculating discounted future net cash flows for reporting
purposes, is not necessarily the most appropriate discount factor, based on
interest rates in effect in the financial markets, and risks associated with the
gas business.

     Generally, the volume of gas production declines as reserves are depleted,
with the rate of decline depending on reservoir characteristics. Except to the
extent we conduct successful exploration and development activities on our other
properties, or acquire properties with proved reserves, or both, our proved
reserves will decline with production. Therefore, our future production depends
on finding or acquiring more reserves.

     The business of exploring for, developing, or acquiring reserves is capital
intensive. To the extent operating cash flow is reduced and external capital
becomes unavailable or limited, our ability to make the necessary capital
investment to maintain or expand our gas reserves asset base would be impaired.
There is no assurance future exploration, development, and acquisition
activities will result in additional proved reserves. Even if revenues increase
because of higher gas prices, increased exploration and development costs could
neutralize the increased revenues.

                                  RISK FACTORS

     An investment in our common stock is speculative in nature and involves a
high degree of risk. You should carefully consider the following risks and the
other information in this prospectus (including the information incorporated by
reference) before investing.

RISK FACTORS INVOLVING THE COMPANY

     LACK OF COALBED METHANE PRODUCTION AND ESTABLISHED RESERVES FOR COALBED
METHANE PROPERTIES MAY SLOW DOWN FURTHER EXPLORATION OF THESE PROPERTIES.
Presently we have only one property in production, for which reserves have been
established (see "Gas Reserves for Bobcat Field" above). We have not drilled and
tested enough wells on the other properties to determine if we have economic
reserves of coalbed methane in place. For some properties, we will have to
establish at least some reserve parameters before gas transmission companies
will build gas lines to our properties, and construction of lines will depend
also on then-current and projected market prices for gas. If we have the

                                        7





necessary capital, we may elect to build our own lines over to existing
transmission lines near two of our properties in the Powder River Basin in
Wyoming. We can't sell production until the lines and associated gathering lines
and compression stations are constructed.

     Due to permitting delays in Montana, we may not realize production from the
Castle Rock and Kirby prospects until late 2003, or later. The Bobcat property
in Wyoming is now in production and other Wyoming properties could be in
production in 2003, but production might be delayed due to low market prices for
gas. Low market prices could delay gas purchasers from building the necessary
lines to move gas from our properties to the major gas transmission lines.

     These factors may make it difficult to raise the amount of capital needed
to further explore the coalbed methane production potential in our properties in
a rapid manner. Therefore we may have to seek to raise capital. In the meantime,
we have only limited working capital. See below.

     CONTINUED LOW GAS PRICES FOR POWDER RIVER BASIN PRODUCTION MAY HURT OUR
BUSINESS. For September, 2002, RMG received an average price of $0.94 per
Million BTU (MMBtu) of gas produced from the Bobcat field (its only producing
field), with prices ranging from $0.46 to $1.22 per MMBtu. The energy content of
our CBM gas is close to one MMBtu per Mcf (from .96 to .98 MMBtu in 1.00 Mcf)
The Bobcat field is not economic at these low prices. These prices approximate
what other producers in the area were receiving in September 2002, and represent
a negative price differential of approximately 73% compared to the average price
of approximately $3.485 per MMBtu received by producers nationwide. This
negative differential usually narrows to within 60% to 30% of a national average
during the winter months. RMG owns a 27.6% working interest (22% net revenue
interest) in the Bobcat project.

     There is no guarantee that increased pipeline capacity planned or under
construction will eliminate the negative price differential or even
significantly reduce it.

     Produced and sold gas (net of gas used as fuel for the compressors)
averaged approximately 1,821 MMBtu per day in January 2003 (503 MMBtu net rate
to our 27.6% working interest). All gas was sold at market prices (average price
$3.03 per MMBtu), which for January 2003 represented a negative differential of
57% from national average gas prices in that month.

     During March 2003, RMG will receive a guaranteed price of $3.49 per MMBtu
for its share of the first 500 MMBtu of gas sold each day with the balance at
market prices.

     During February 2003, RMG received a guaranteed price of $3.07 per MMBtu
for its share of the first 1,000 MMBtu of gas sold each day, and an average
price of $4.25 per MMBtu for the balance of gas produced. This guaranteed
pricing arrangement may be available to RMG monthly, at prices negotiated with
the gas buyer at the end of each preceding month, or, RMG may elect to sell on
daily market prices.

     The guaranteed pricing mechanism may, or may not, prove advantageous to RMG
in those months it is utilized, depending on market price performance during
those months, and in any event, would not insulate RMG from the negative price
differential to the extent it is a significant influence on prices.

     The return of sustained low gas prices would impair our ability to raise
capital for RMG and reduce revenues from production coming on line. See the
discussion under the caption "Gathering and Transmission of CBM Gas" in the Form
10-K/A for fiscal 2002.

                                        8





     WE MAY HAVE TO BEGIN TO CURTAIL OPERATIONS IF WE DON'T RAISE MORE CAPITAL
BY JULY 2003 . At November 30, 2002, U.S. Energy Corp. had working capital of
$2,166,600, and an accumulated deficit of $36,954,100. Our current level of
operations, including general and administrative overhead, mineral operations
(primarily holding costs for the uranium and gold properties), and costs to
comply with other property lease and permitting obligations for the coalbed
properties, are estimated to cost $2,900,000 for the six months ending June 30,
2003. However, if we can't realize cash from liquidating assets, or other
sources, or if RMG spends more money on exploration than will be covered by
current arrangements, then under these circumstances additional equity financing
may be necessary to sustain operations starting in July 2003. There are no
current commitments for such future financing as may be necessary.

     Our strategy for RMG contemplates a total capital budget of up to
$50,000,000 through calendar 2003 to continue exploring our coalbed methane
properties, put them into production, and to acquire more properties. The cash
requirements for our coalbed methane business are in addition to working capital
requirements. However, lack of production and established reserves may make it
difficult to raise this amount of money in the near future. Therefore, we may
have to seek to raise capital in smaller amounts over time, which efforts
probably will extend well into calendar 2004. See the preceding risk factor.

     WE ARE SUBJECT TO CERTAIN KINDS OF RISK WHICH ARE UNIQUE TO THE MINERALS
BUSINESS. The exploration for and production of minerals is highly speculative
and involves risks different from and in some instances greater than risks
encountered by companies in other industries. Many exploration programs do not
result in the discovery of mineralization and any mineralization discovered may
not be of sufficient quantity or quality. Also, the mere discovery of promising
mineralization may not warrant production, because the minerals (including
methane gas) may be difficult or impossible to extract (produce) on a profitable
basis.

     Profitability of any mining and production we may conduct will involve a
number of factors, including, but not limited to: the ability to obtain all
required permits; costs of bringing the property into production; the
construction of adequate production facilities; the availability and costs of
financing; keeping ongoing costs of production at economic levels; and market
prices for the metals or hydrocarbons to be produced staying above production
costs. Our properties, or properties we might acquire in the future, may not
contain deposits of minerals or coalbed methane gas that will be profitable to
produce.

     In addition, all forms of mineral (and oil and gas and coalbed methane)
exploration and production require permits to have been issued by various
federal and state agencies. See below.

     DELAYS IN OBTAINING PERMITS FOR METHANE WELLS COULD IMPAIR OUR BUSINESS.
Drilling and producing coalbed methane wells requires obtaining permits from
various governmental agencies. The ease of obtaining the necessary permits
depends on the type of mineral ownership and the state in which the property is
located. Intermittent delays in the permitting process can reasonably be
expected throughout the development of any play. For example, there is currently
a temporary moratorium for drilling coalbed methane wells on fee and state lands
in Montana. We may shift our exploration and development strategy as needed to
accommodate the permitting process. As with all governmental permit processes,
permits may not be issued in a timely fashion or in a form consistent with our
plan of operations.

     THE COMPANY'S POISON PILL COULD DISCOURAGE SOME ADVANTAGEOUS TRANSACTIONS.
We have adopted a shareholder rights plan, also known as a poison pill (see
"Description of Securities"). The plan is designed to discourage a takeover of
the company at an unfair low price. However, it is possible that

                                        9





the board of directors and the takeover acquiror would not agree on a higher
price, in which case the takeover might be abandoned, even though the takeover
price was at a significant premium to market prices. Therefore, as a result of
the mere existence of the plan, shareholders would not receive the premium
price.

     COMPLIANCE WITH ENVIRONMENTAL REGULATIONS MAY BE COSTLY. Our business
(mostly coalbed methane) is intensely regulated by government agencies. Permits
are required to drill and pump methane wells, explore for minerals, operate
mines, build and operate processing plants, and handle and store waste. The
regulations under which permits are issued change from time to time to reflect
changes in public policy or scientific understanding of issues. If the economics
of a project would not justify the changes, we might have to abandon the
project.

     The company must comply with numerous environmental regulations on a
continuous basis, to comply with the United States Clean Air Act, the Clean
Water Act, the Resource Conservation and Recovery Act ("RCRA"), and the
Comprehensive Environmental Response Compensation Liability Act ("CERCLA"). For
example, water and dust discharged from mines and tailings from prior mining or
milling operations must be monitored and contained and reports filed with
federal, state and county regulatory authorities. Additional monitoring and
reporting is required by the United States Nuclear Regulatory Commission for
uranium mills even if not currently operating (like the company's uranium mill
at Ticaboo, Utah). The Abandoned Mine Reclamation Act in Wyoming and similar
laws in other states where we have properties impose reclamation obligations on
abandoned mining properties, in addition to or in conjunction with federal
statutes.

     Failure to comply with these regulations could result in substantial fines
and environmental remediation orders. For information on the company's bonding
requirements to date, see note K to the audited financial statements in the 2002
Form 10-K/A.

     COMMODITY PRICE FLUCTUATIONS MAY BE DIFFICULT TO MANAGE AND COULD CAUSE
LOSSES. Gold, uranium and gas prices can be volatile. Sharp swings in market
prices make budgeting and operations more difficult. Sustained lower prices can
result in impairment of the financial value of the mineral property purchased as
well as the facilities built to process the material (such as mills or gas
compression stations). Hedging activities, if available for the commodity, can
protect against price swings but may result in locking a company into a lower
than market price over time.

     FUTURE EQUITY TRANSACTIONS, INCLUDING EXERCISE OF OPTIONS OR WARRANTS,
COULD RESULT IN DILUTION. From time to time the company sells restricted stock
and warrants, and convertible debt to investors in private placements conducted
by broker-dealers, or in negotiated transactions. Because the stock is
restricted, the stock is sold at a greater discount to market prices compared to
a public stock offering, and the exercise price of the warrants sometimes is at
or even lower than market prices. These transactions cause dilution to existing
shareholders. Also, from time to time, options are issued to employees and third
parties, with exercise prices equal to market. Exercise of in-the-money options
and warrants will result in dilution to existing shareholders; the amount of
dilution will depend on the spread between market and exercise price, and the
number of shares involved. The company will continue to grant options to
employees with exercise prices equal to market price at grant date, and in the
future may sell restricted stock and warrants, all of which may result in
dilution to existing shareholders. See also "Registration for Resale of
Additional Shares May Depress Market Prices."

     TERMS OF SUBSEQUENT FINANCINGS MAY ADVERSELY IMPACT YOUR INVESTMENT. We may
have to raise equity, debt or preferred stock financing in the future. Your
rights and the value of your investment in the common stock could be reduced.
For example, if we have to issue secured debt securities, the holders of the
debt would have a claim to our assets that would be prior to the rights of
stockholders until the debt is paid. Interest on these debt securities would
increase costs and negatively impact operating results. Preferred stock could be
issued in series from time to time with such designations, rights, preferences,
and limitations as needed to raise capital. The terms of preferred stock could
be more advantageous to those investors than to the holders of common stock. In
addition, if we need to raise more equity capital from sale of common stock,
institutional or other investors may negotiate terms at least and possibly more
favorable than the terms of this offering. Shares of common stock which we sell
could be sold into the market, which could adversely affect market price. See
"Risk Factor Involving This Offering" below.

     THERE MAY BE RISKS RELATED TO OUR PRIOR USE OF ARTHUR ANDERSEN LLP AS OUR
INDEPENDENT CERTIFIED PUBLIC ACCOUNTANT. The consolidated balance sheet of U.S.
Energy Corp. for the year ended May 31, 2000 and the related consolidated
statements of operations, shareholders equity and cash flows for each of the two
years in the period ended May 31, 2000 included in the Annual Report on Form
10-K/A for the year ended May 31, 2002, as amended, and incorporated by
reference into this prospectus, to the extent and for the periods indicated in
their report, have been audited by Arthur Andersen LLP, independent certified
public accountants.

     The recent obstruction of justice conviction of Arthur Andersen LLP may
adversely affect Arthur Andersen LLP's ability to satisfy any claims arising
from the provision of auditing services to us, including claims that may arise
out of Arthur Andersen LLP's audit of our financial statements incorporated by
reference in this prospectus for the years ended May 31, 2000. Arthur Andersen
LLP has been convicted of federal obstruction of justice arising from the
government's investigation of Enron Corp. Should we seek to access the public
capital markets to raise money for the Company before October 1, 2003, SEC rules
will require us to include or incorporate by reference in any prospectus audited
financial statements for the fiscal year ended May 31, 2000, which has been
audited by Arthur Andersen LLP. If the SEC ceases accepting financial statements
audited by Arthur Andersen LLP, we could be unable to access the public capital
markets until after October 1, 2003, unless Grant Thornton LLP, our current
independent accounting firm, or another independent accounting firm, is able to
re-audit the financial statements originally audited by Arthur Andersen LLP. Any
delay or inability to access the public capital markets caused by these
circumstances could have a material adverse effect on our business,
profitability, and growth prospectus.

     The SEC's rules would not require the use of the financial statements for
the fiscal year ended May 31, 2000, in any prospectus we file after October 1,
2003.

RISK FACTOR INVOLVING THIS OFFERING

     REGISTRATION FOR RESALE OF ADDITIONAL SHARES MAY DEPRESS MARKET PRICES. In
February and March, 2002 we sold 281,926 shares of restricted stock, at $3.25
per share, and two year warrants to purchase 56,383 shares of stock, with an
exercise price of $4.00 per share, for $916,254 cash. We also issued 20,000
shares to Robert H. Taggart, Jr. in exchange for unexercised warrants and
services. 15,385 of the shares sold in February and March 2002 have been sold by
two of the original investors under rule 144. It is anticipated that resale of
the remaining 266,541 shares of USE common stock, and resale of the 56,383
shares on exercise of the warrants, into the public market will be registered on
a Form S-3 registration statement. An initial registration statement for resale
of these shares was filed with the Securities and Exchange Commission in May
2002.

     A third Form S-3 registration statement will be filed with the Securities
and Exchange Commission also in March 2003 for the shares covered by the
transactions described below.


                                       11





     On May 30, 2002, we borrowed $1,000,000 from Caydal, LLC, a private lender
and shareholder of U.S. Energy Corp. The two year secured loan is convertible
into restricted shares of U.S. Energy Corp. common stock at the rate of 1 share
for $3.00 of principal (a maximum of 333,333 shares), or into restricted shares
of common stock of our subsidiary Rocky Mountain Gas, Inc. at the rate of 1
share for $1.50 of principal. In addition, USE issued to the lender a warrant to
purchase until May 30, 2005, 120,000 shares of USE restricted common stock, at
$3.00 per share, and RMG issued to the lender a warrant to purchase until May
30, 2005, 120,000 shares of RMG restricted common stock, at $1.50 per share.
VentureRound Group ("VRG"), a licensed broker-dealer, acted as the lender's
agent in the transaction, for which services USE paid VRG $25,000 cash and
issued to 31 persons who own equity interests in VRG warrants to purchase until
May 30, 2005, 30,000 restricted shares of common stock of U.S. Energy Corp., at
$3.00 per share.

     VRG also served as financial advisor to the company in connection with a
private financing by the company in February and March 2002. In connection with
that transaction, warrants to purchase 28,192 shares at $4.00 are held by 36
persons who own equity interests in VRG, issued as of March 25, 2002, expiring
on March 25, 2004. In connection with an earlier financing by the company, the
company issued warrants to purchase 3,000 shares at $3.75 to one person who owns
an equity interest in and is associated (licensed) with VRG; these warrants were
issued as of October 18, 2001 and expire on October 18, 2006.

     In each of the financing or advisory transactions in which VRG was
involved, the services provided by VRG were provided by persons associated with
(licensed with) a broker-dealer registered with the Securities and Exchange
Commission. The warrants to purchase stock in USE were issued in partial
consideration for these services provided by licensed persons, but distributed
to the owners of VRG, including the persons licensed as brokers (who also own
equity interests in VRG). Those persons who received warrants as owners of VRG,
but who are not licensed as brokers, did not provide securities- transaction
services and did not otherwise pay for the warrants.

     Effective September 19, 2002, we entered into amendments to warrants that
were to expire on that date. The original warrants were issued for the exercise
of up to 67,025 shares of the company's common stock to persons who had been
associated (licensed) with a broker-dealer which raised funds in 1997 for
Yellowstone Fuels Corp., a subsidiary of the company. As consideration for an
extension of time for exercising the warrants, the holders agreed to waive
certain rights relating to anti-dilutive and cashless exercise provisions of the
original warrants. The warrants, which now cover 74,564 shares, are exercisable
at $3.64 per share, and now expire on July 19, 2003.

     On November 19, 2002, we borrowed $500,000 from Tsunami Partners, L.P., a
private lender. The two year secured loan is convertible into restricted shares
of U.S. Energy Corp. common stock at the rate of 1 share for $3.00 of principal
(a maximum of 166,666 shares), or into restricted shares of common stock of our
subsidiary Rocky Mountain Gas, Inc. at the rate of 1 share for $2.00 of
principal. In addition, U.S. Energy Corp. issued to the lender a warrant to
purchase until November 19, 2005, 60,000 shares of U.S. Energy Corp. restricted
common stock, at $3.00 per share, and RMG issued to the lender a warrant to
purchase until November 19, 2005, 60,000 shares of RMG restricted common stock,
at $2.00 per share. VRG acted as the agent in the transaction, for which
services USE paid VRG $20,000 cash and issued a warrant to purchase until
November 19, 2005, 15,000 restricted shares of common stock of U.S. Energy
Corp., at $3.00 per share. These warrants were issued to the equity owners of
VRG (see above), including Robert H. Taggart, a licensed broker who provided
securities-transaction services.


                                       12





     On December 9, 2002, the company and its subsidiary Sutter Gold Mining
Company entered into a settlement agreement relating to certain litigation
involving SGMC. As a result of the settlement the company issued 20,000 shares
of U.S. Energy Corp. common stock to trusts.

     On February 3, 2003, the company issued 8,231 shares to Philip A. Nicholas
as partial payment for legal services; and 5,474 shares and an option to
purchase 18,000 shares of the company's common stock at $3.00 per share as
partial payment for legal services to Robert A. Nicholas.

     It is anticipated that resale of the foregoing 33,705 shares of USE common
stock, and resale of the 330,756 shares on exercise of the warrants, 18,000
shares on exercise of options and 499,999 shares which may be issued by
conversion of debt, into the public market (a total of 882,460 shares) will be
registered on the third Form S-3 registration statement to be filed with the
Securities and Exchange Commission in March 2003.

     Such resales could adversely affect market prices for the investors who buy
shares in this offering.

     From time to time, we may sell restricted shares to raise capital.
Registration for resale of such additional shares could adversely affect market
prices for investors who buy shares in this offering.

                       REPRESENTATIONS ABOUT THIS OFFERING

     We have not authorized anyone to provide you with information different
from that contained in this prospectus. This prospectus is not an offer to sell
nor does it seek an offer to buy the shares in any jurisdiction where this offer
or sale is not permitted. The information contained in this prospectus is
accurate only as of the date of this prospectus (or any supplement), regardless
of when it is delivered or when any shares are sold.

                           FORWARD LOOKING STATEMENTS

     We make statements in this prospectus which are considered to be "forward
looking" statements. All statements (other than statements of historical fact)
about financial and business strategy and the performance objectives of
management are forward-looking statements. These forward-looking statements are
based on the beliefs of management, as well as assumptions made by and
information currently available to them. These statements involve risks that are
both known and unknown, including unexpected economic and market factors,
failure to accurately forecast operating and capital expenditures and capital
needs (due to rising costs and/or different drilling and production conditions
in the field), changes in timing or conditions for getting regulatory approvals
to drill coalbed methane wells where needed, and other business factors. The use
of the words "anticipate," "believe," "estimate," "expect," "may," "will,"
"should," "continue," "intend" and similar words or phrases, are intended by us
to identify forward-looking statements (also known as "cautionary statements"
because you should be cautious in evaluating such statements in the context of
all the information in this prospectus and the information incorporated by
reference into this prospectus). These statements reflect our current views with
respect to future events. They are subject to the realization in fact of
assumptions, but what we now think will happen may be turn out much different,
and our assumptions may prove to have been inaccurate or incomplete.

     The investment risks discussed under "Risk Factors" specifically address
all of the material risk factors that may influence future operating results and
financial performance. Those investment risks are not "boiler plate" but are
intended to tell you about the uncertainties and risks inherent in our business
at the present time which you need to evaluate before making your investment
decision.

                            DESCRIPTION OF SECURITIES

     COMMON STOCK. We are authorized by our articles of incorporation to issue
an unlimited number of shares of common stock, $0.01 par value, and 100,000
shares of preferred stock, $0.01 par value.

     Shares of common stock may be issued for such consideration and on such
terms as determined by the board of directors, without shareholder approval.
Holders are entitled to receive dividends when and as declared by the board of
directors out of funds legally available therefor. There are no restrictions on
payment of cash dividends. Cash dividends have not been declared on the common
stock, although a 1 for 10 stock dividend was declared in November 1990. It is
anticipated that future earnings would be reinvested into operations and not
declared as dividends on the common stock. All holders of shares of common stock
have equal voting rights, and the shares of common stock sold in this offering
will have the same rights. Holders of shares of common stock are entitled to one
vote per share on all matters upon which such holders are entitled to vote, and
further have the right to cumulate their votes in elections of directors.
Cumulation means multiplying the number of shares held, by the number of
nominees to the board of directors, then voting the product among the nominees
as desired. Directors are elected by a plurality of the votes cast.

     Shares of common stock sold in this offering are fully-paid and
nonassessable shares of U.S. Energy Corp.

         Pursuant to our articles of incorporation and as permitted by Wyoming
law, shares of common stock held by our subsidiaries may be voted by such
subsidiaries as determined by the board of directors of each, in elections of
directors and other matters brought before shareholders.

     In September 2001, the company adopted a shareholder rights plan ("poison
pill") and filed the plan with the Securities and Exchange Commission as an
exhibit to Form 8-A. The following three paragraphs briefly state principal
features of the plan, which are qualified by reference to the complete plan,
which is incorporated by reference into this prospectus.

     Under the plan, the holder of each share of common stock has the right to
purchase (when the rights become exercisable) from the company one-one
thousandth (1/1,000th) of one (1) share of Series P preferred stock at price of
$200.00 for each one-one thousandth (1/1,000th) share of such preferred stock.
The purpose of the plan is to deter an unfairly low priced hostile takeover of
the company, by encouraging a hostile party to negotiate a fair offer with the
board of directors and thus eliminate the poison pill.

     The rights trade with the common stock and aren't separable therefrom; no
separate certificate for the rights is issued unless and until there is a
hostile takeover attempted, after which time separate and tradable rights
certificates would be issued.

     The rights are not exercisable and never can be unless and until a hostile
(not negotiated with the board) takeover of the company is initiated with the
objective of acquiring 15% of the company's voting stock. If before the takeover
is launched the hostile party comes to agreement with the board of directors
about price and terms and makes a "qualified offer" to buy the stock of the
company, then the board of directors may redeem (buy back) the rights for $0.01
each. But, if such a "qualified offer" isn't agreed upon, then the rights are
exercisable for preferred stock, which in turn would enable the holder to
convert the preferred stock into voting common stock of the company at a price
equal to one-half the market price.


                                       14





     PREFERRED STOCK. Shares of preferred stock may be issued by the board of
directors with such dividend, liquidation, voting and conversion features as may
be determined by the board of directors without shareholder approval. In June
2000, we established a Series A Convertible Preferred Stock, for which 1,000
shares of preferred stock are reserved for sale at $10,000 per share; 200 shares
were issued and outstanding at November 30, 2001. In January 2002, we converted
the 200 outstanding shares of Series A stock by issuing 513,140 shares of
restricted common stock to the holder, based on $2,000,000 invested plus $11,507
of interest (annual rate of 7.5%) which accrued in December 2001 (previous
interest had been paid in cash), divided by $3.92 (market price for USE stock on
December 5, 2001).

persons or entities other than employees, officers or directors of the company)

                              SELLING SHAREHOLDERS

     This prospectus covers the offer and sale by the selling shareholders of up

shareholders. All shares issued are restricted securities as that term is
defined in rule 144 of the Securities and Exchange Commission under the

are sold pursuant to this prospectus, or otherwise are sold in compliance with
rule 144 or the restriction removed in accordance with rule 144(k).

     The selling shareholders are not affiliates of the company or any
subsidiary of the company.

     The shares covered by this prospectus consist of 513,140 shares of
restricted common stock issued to Amiee Flanigan Glas, upon conversion of 200

                                       18





     The shares owned by the selling shareholders are registered under rule 415
of the general rules and regulations of the Securities and Exchange Commission,
concerning delayed and continuous offers and sales of securities. In regard to
the offer and sale of such shares, we have made certain undertakings in Part II
of the registration statement of which this prospectus is part, by which, in
general, we have committed to keep this prospectus current during any period in
which the selling shareholders make offers to sell the covered securities
pursuant to rule 415.

                              PLAN OF DISTRIBUTION

     The selling shareholders and any of their pledgees, donees, assignees and
successors-in-interest may, from time to time, sell any or all of their shares
of common stock on any stock exchange, market or trading facility on which the
shares are traded. These sales may be at fixed or negotiated prices. The selling
shareholders may use any one or more of the following methods when selling
shares:

     O    ordinary brokerage transactions and transactions in which the
          broker-dealer solicits purchasers;

     O    block trades in which the broker-dealer will attempt to sell the
          shares as agent but may position and resell a portion of the block as
          principal to facilitate the transaction;

     O    purchases by a broker-dealer as principal and resale by the
          broker-dealer for its account;

     O    an exchange distribution in accordance with the rules of the
          applicable exchange;

     O    privately negotiated transactions;

     O    short sales (sales of shares not owned in hopes of a decline in market
          price so the seller can purchase in the market at a lower price to be
          able to deliver the shares sold);

     O    broker-dealers may agree with the selling shareholder to sell a
          specified number of such shares at a stipulated price per share;

     O    a combination of any such methods of sale; and

     O    any other method permitted pursuant to applicable law.

     The selling shareholders also may resell all or a portion of the shares in
open market transactions in reliance upon rule 144 under the 1933 Act, provided
they meet the criteria and conform to the requirements of the rule.

     The selling shareholders may also engage in short sales against the box (a
short sale where the seller borrows the stock from a third party, hoping the
market price will decline), puts and calls and other transactions in securities
of the company or derivatives of company securities and may sell or deliver
shares in connection with these trades. The selling shareholders may pledge
shares to brokers under the margin provisions of customer agreements. If a
selling shareholder defaults on a margin loan, the broker may, from time to
time, offer and sell the pledged shares. The selling shareholders have advised
the company that they have not entered into any agreements, understandings or
arrangements with any underwriters or broker-dealers regarding the sale of their
shares other than ordinary course brokerage arrangements, nor is there an
underwriter or coordinating broker acting in connection with the proposed sale
of shares by the selling shareholders.


                                       19





     Broker-dealers engaged by the selling shareholders may arrange for other
brokers-dealers to participate in sales. Broker-dealers may receive commissions
or discounts from the selling shareholders (or, if any broker-dealer acts as
agent for the purchaser of shares, from the purchaser) in amounts to be
negotiated. The selling shareholders do not expect these commissions and
discounts to exceed what is customary in the types of transactions involved.

     We are required to pay all fees and expenses incident to the registration
of resale of the shares covered by this prospectus. However, all discounts,
commissions or fees incurred in connection with the sale of the shares offered
hereby will be paid by the selling shareholders. The company has agreed to
indemnify the selling shareholders against certain losses, claims, damages and
liabilities, including liabilities under the 1933 Act. We have been advised that
in the opinion of the Securities and Exchange Commission, indemnification for
liabilities under the 1933 Act is against public policy, and therefore is
unenforceable. See below.

     In order to comply with the securities laws of certain states, if
applicable, the shares will be sold in such jurisdictions, if required, only
through registered or licensed brokers or dealers. In addition, in certain
states the shares may not be sold unless the shares have been registered or
qualified for sale in such state or an exemption from registration or
qualification is available.

                      DISCLOSURE OF COMMISSION POSITION ON
                 INDEMNIFICATION FOR SECURITIES ACT LIABILITIES

     Our articles of incorporation and bylaws provide that we shall indemnify
directors provided that the indemnification shall not eliminate or limit the
liability of a director for breach of the director's duty or loyalty to the
corporation or its stockholders, or for acts of omission not in good faith or
which involve intentional misconduct or a knowing violation of law.

     Wyoming law permits a corporation, under specified circumstances, to
indemnify its directors, officers, employees or agents against expenses
(including attorney's fees), judgments, fines and amounts paid in settlements
actually and reasonably incurred by them in connection with any action, suit or
proceeding brought by third parties by reason of the fact that they were or are
directors, officers, employees or agents of the corporation, if these directors,
officers, employees or agents acted in good faith and in a manner they
reasonably believed to be in or not opposed to the best interests of the
corporation and, with respect to any criminal action or proceedings, had no
reason to believe their conduct was unlawful. In a derivative action, i.e., one
by or in the right of the corporation, indemnification may be made only for
expenses actually and reasonably incurred by directors, officers, employees or
agent in connection with the defense or settlement of an action or suit, and
only with respect to a matter as to which they shall have acted in good faith
and in a manner they reasonably believed to be in or not opposed to the best
interests of the corporation, except that no indemnification shall be made if
such person shall have been adjudged liable to the corporation, unless and only
to the extent that the court in which the action or suit was brought shall
determine upon application that the defendant directors, officers, employees or
agents are fairly and reasonably entitled to indemnify for such expenses despite
such adjudication of liability.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
company pursuant to the foregoing provisions, or otherwise (for example, in
connection with the sale of securities), we have been advised that in the
opinion of the Commission such indemnification is against public policy as
expressed in the 1933 Act, and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the company of expenses incurred or paid by a director, officer or controlling
person in the successful defense of any action, suit or proceeding) is asserted
by such director, officer or controlling person in connection with the
securities being registered, the company will, unless in the opinion of its

                                       20





counsel the matter has been settled by controlling precedent, submit to a court
of appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the 1933 Securities Act, and will be
governed by the final adjudication of such issue.
