Prospectus                                             Subject to Completion,
                                                       Dated February ____, 1999
                                U.S. ENERGY CORP.

                  OFFER TO EXCHANGE SHARES OF U.S. ENERGY CORP.
                     FOR SHARES OF YELLOW STONE FUELS CORP.
   --------------------------------------------------------------------------

         U.S. Energy Corp. ("USE") offers to issue shares of USE Common Stock in
exchange  for the shares of Common  Stock of Yellow  Stone Fuels Corp.  ("YSFC")
owned by persons who bought  YSFC shares  through  American  Fronteer  Financial
Corporation  ("AFFC",  formerly RAF Financial  Corporation).  The persons who so
invested in YSFC are referred to in this Prospectus as the "shareholders."  AFFC
acted as the placement agent for YSFC in a private  placement  financing in late
1997 and early 1998. USE also offers to issue Warrants to Purchase  Common Stock
of USE ("USE  Warrants") in exchange for the Warrants to Purchase  Common Shares
of YSFC ("YSFC Warrants") which were issued to AFFC as partial  compensation for
its placement  agent  services.  YSFC  shareholders  (including  holders of YSFC
Warrants who have exercised  their Warrants for YSFC shares) may exchange all or
part of their YSFC shares for USE shares.  Holders of unexercised  YSFC Warrants
may exchange all or some of their  Warrants for USE  Warrants.  Shareholders  of
YSFC who did not invest in YSFC through AFFC cannot participate in this Exchange
Offer.

         This Exchange Offer is made pursuant to the September 17, 1997 Exchange
Rights  Agreement  between  YSFC,  USE  and  AFFC.  There  are  no  underwriting
arrangements  known to USE in connection with this Exchange  Offer.  Any selling
discounts or commissions due on sale of the USE shares or USE Warrants  acquired
pursuant to this Exchange Offer will be paid by the sellers.

         The number of USE shares  offered to each YSFC  shareholder is equal to
(x) the original  investment amount plus 10 percent annual interest,  divided by
(y) the average of the  closing  Nasdaq NMS bid prices for a share of USE Common
Stock for the five  trading  days before USE  receives the Notice of Election to
Exchange  from each YSFC  shareholder  and each  holder  of YSFC  Warrants.  The
average  price for USE Common  Stock,  as so  determined  from time to time,  is
referred  to in this  Prospectus  as the "USE  share  value."  The number of USE
Warrants  offered to each holder of YSFC  Warrants is equal to (x) the number of
YSFC shares underlying the holder's YSFC Warrants  multiplied by $2.00,  divided
by (y) the USE share value. The USE Warrants will be exercisable until September
19, 2002 (the original term of the YSFC  Warrants) at an exercise  price per USE
share which is equal to the USE share value.  For information on how to exchange
YSFC shares or YSFC  Warrants,  please see "Terms of the Exchange." The Exchange
Offer will expire on  September  22, 1999.  No meeting of the YSFC  shareholders
will be held in connection  with this Exchange  Offer.  On February 16, 1999 the
USE share value was $3.00.

                             SUMMARY OF THE OFFERING

         U.S.  Energy  Corp.  U.S.  Energy  Corp.  ("USE") is in the business of
acquiring,  exploring,  developing and/or selling or leasing mineral properties,
and the mining and  marketing of minerals.  USE is now engaged in two  principal
mineral  sectors,  uranium and gold; both sectors are in the development  stage.
The most significant  uranium properties are located on Green Mountain and Sheep
Mountain in Wyoming,  and in  southeast  Utah.  The gold  property is located in
Sutter  Creek,  California,  east of  Sacramento.  Interests  are  held in other
mineral  properties  (principally  molybdenum),  but  are  either  non-operating
interests  or  undeveloped  claims.  USE  also  carries  on  small  oil  and gas
operations in Montana and Wyoming.  Other USE business  segments are  commercial
operations (real estate and general aviation) and construction  operations.  USE
has a May 31 fiscal year.

         USE  was  incorporated  in  Wyoming  in  1966.  USE and  Crested  Corp.
("Crested")  originally were independent  companies,  with two common affiliates
(John L.  Larsen and Max T.  Evans).  In 1980,  USE and  Crested  formed a 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 the debts by Crested  issuing  common stock to USE,  Crested became a
majority-owned  subsidiary of USE in fiscal 1993.  All of USE's (and  Crested's)
operations are in the United States.  Principal executive offices are located in
the Glen L. Larsen  building  at 877 North 8th Street  West,  Riverton,  Wyoming
82501, telephone 307.856.9271.

         Most of USE  operations  are  conducted  through a joint  venture  with
Crested and various  jointly-owned  subsidiaries  of USE and Crested.  The joint
venture  with  Crested  is  referred  to in this  Prospectus  as  "USECC".  Gold
operations are conducted  through Sutter Gold Mining  Company,  a  jointly-owned
subsidiary.  Construction  operations  are carried on  primarily  through  USE's
subsidiary Four Nines Gold, Inc. ("FNG").

         In fiscal  1998,  USE and  USECC  signed an  agreement  with  Kennecott
Uranium Company  ("Kennecott"),  for the purchase of Kennecott's interest in the
Wyoming uranium project held by the Green Mountain Mining Venture ("GMMV"). This
agreement  expired on October  30,  1998.  Please see  "Information  About USE -
Business and Properties -  Minerals-Uranium-The  Green  Mountain  Mining Project
Amendment to GMMV."

         In fiscal 1998, USE and Crested continued the development of the GMMV's
Jackpot uranium mine and the upgrade of the GMMV's  Sweetwater  uranium mill and
the Shootaring Canyon uranium mill in southeast Utah (owned by Plateau Resources
Ltd., a wholly-owned USE subsidiary).

         For fiscal 1999 and 2000, USE seeks the financing necessary to continue
development  work at the  Jackpot  Mine.  In late July 1998,  USE,  Crested  and
Kennecott made a business  decision to temporarily cease development work at the
Jackpot  Mine;  this  decision  was based upon the expected  negative  impact on
uranium prices from the uranium inventory which USEC Inc.  announced was held in
its inventory and could be sold into the uranium  market.  USEC Inc.  originally
was the United States Enrichment Corporation,  which was created in 1992 to hold
the uranium  enrichment  facilities of the United  States  Department of Energy.
USEC Inc.  is not  affiliated  with USE or USECC.  However,  other  factors  are
affecting  the  global  uranium  market   (reductions  in  current  and  planned
production).  These other factors may justify the resumption of development work
and putting the Utah uranium  properties into production in the near-term may be
warranted. See "Information About USE - Business and Properties - Uranium Market
Information."  USE is in discussions with various sources of capital to fund its
uranium  projects  in Utah and  Wyoming,  but no  funding  agreements  have been
reached  as of the  date of  this  Prospectus.  Kennecott  has  recently  "fully
impaired" its investment in the GMMV. See the GMMV Financial  Statements in this
Prospectus.  For a  discussion  of this  matter,  see  "Information  About USE -
Business  and  Properties  -  Minerals  - Uranium - The  Green  Mountain  Mining
Venture."

                                        3

         USE also is refining plans to build a mine and mill for the Sutter Gold
Mine  Project in  California  (held by Sutter  Gold  Mining  Company),  with the
objective of  continuing  mine  development,  building a gold mill and producing
gold, possibly in fiscal 2000.  Permitting and some capital costs will be funded
internally by Sutter Gold Mining Company.  Additional  funding will be needed to
build the mine and mill, however, there are no funding agreements as of the date
of this Prospectus. See "Information About USE - Gold."

         Yellow  Stone  Fuels  Corp.  Yellow  Stone  Fuels  Corp.  ("YSFC") is a
corporation  organized  under the laws of Ontario,  Canada.  All  operations are
conducted  through  Yellow Stone Fuels,  Inc.,  a Wyoming  corporation  which is
wholly-owned  by YSFC.  Through its  subsidiary,  YSFC holds  (through  lease or
ownership)  approximately  9,480 acres of  properties in Wyoming and New Mexico.
The properties are believed to be suitable for uranium  production  using the in
situ leach ("ISL") process. ISL mining pumps fortified water through underground
uranium deposits to dissolve  uranium,  then pumps the pregnant solution back to
the surface for processing to remove and concentrate the uranium. None of YSFC's
properties are in production.  YSFC will require  significant amounts of capital
to start any  mining  operations,  but YSFC does not have such  capital.  YSFC's
business of acquiring  uranium  properties  will not be affected by the Exchange
Offer.

         USE and  Crested  own a total of  3,000,000  (25.6%)  of the issued and

         Comparative  Market  Value  of the  Securities  of USE  and  YSFC.  The
Exchange  Rights  Agreement  was signed on September  17, 1997. On September 16,
1997 the closing bid price of USE Common Stock was $10.125.  On that date, there
was no market for YSFC Common Stock and YSFC remains a private company as of the
date of this  Prospectus.  However,  as of September 16, 1997, AFFC and YSFC had
signed an Agency  Agreement  for AFFC to sell shares of YSFC  Common  Stock in a
private  placement  at a price of $2.00 per share.  Therefore,  $2.00  should be
regarded as the  historical  per share price for YSFC as of September  16, 1997.
Because the Exchange Rights Agreement was intended to make the dollar investment
in YSFC  shares  equal to the  dollar  value of USE shares  (except  for the 10%
interest factor), the shares of YSFC will be worth the same dollar amount of USE
shares when an exchange is made,  compared to the dollar investment on September
16, 1997.

         Comparison of the Percentage of Outstanding Shares of USE and YSFC Held
by Affiliates. No Voting Is Required.

         As of  the  date  of  this  Prospectus,  the  officers,  directors  and
affiliates  of USE  own  (or  control  the  voting  of)  21% of the  issued  and
outstanding shares of USE Common Stock (not including unexercised options to buy
USE Common Stock). The officers, directors and affiliates of YSFC, including USE
and  Crested,  own (or control the voting of) 70% of the issued and  outstanding
shares of YSFC Common Stock.
See "Voting and Management Information."

         No  approval by the  shareholders  of either USE or YSFC is required in
connection with this Exchange Offer.

         No Regulatory  Approvals  Required.  No Dissenters' Rights of Appraisal
Apply. No approval from any federal or state regulatory  agency will be required
to be obtained in connection with this Exchange Offer. No dissenters'  rights of
appraisal  are  available  to the YSFC  shareholders  in  connection  with  this
Exchange Offer,  which means that YSFC  shareholders may exchange all or part of
their YSFC shares, but they do not have the right to sell back their YSFC shares
to YSFC for cash equal to the "fair value" of the YSFC  shares.  See "Voting and
Management Information."

         Tax  Consequences.  YSFC  shareholders who elect to participate in this
Exchange  Offer may  realize  income in the form of capital  gain when they sell
their USE shares in the future.  However,  the  participating  YSFC shareholders
will  realize  ordinary  income  equal to 10 percent  annual  interest  on their
original investment in YSFC. See "Terms of the Exchange Offer."

         RISK FACTORS

         The YSFC  shareholders and the holders of the YSFC Warrants should note
that the business of USE is subject to certain risks, including the following:


                                        9

<PAGE>



         1. Limited  Development  Capital.  USE's expected cash requirements for
the balance of fiscal  1999 and fiscal 2000 are the funding of on-going  general
and administrative  expenses; mine and mill development and holding costs of the
Sutter gold property;  holding  (standby) costs for the uranium mills in Wyoming
and southeastern  Utah; SMP and GMMV mine care and maintenance  costs; and costs
to acquire uranium oxide under the supply contract which USE and Crested hold.

         As of the date of this Prospectus,  USE does not have enough capital or
credit resources to put its uranium and/or gold properties into production,  and
has  limited  capital to start  construction  work on the gold  property.  It is
possible,  furthermore, that Kennecott will not fund any more development of the
GMMV's Jackpot Mine. Therefore, USE will need substantial capital to prepare its
properties  for  production  and mine and mill  uranium  and/or  gold from these
properties. USE may not obtain the necessary capital.

         See "Information About USE - USE's Management's Discussion and Analysis
of Financial Condition and Results of Operations" for additional  information on
working capital requirements and capital resources.
See also Risk Factors 2 and 3 below.

         2. Sutter Gold - No Current Mining  Operations or Gold Production.  USE
and Crested have invested  substantial funds in capitalized costs and additional
funds for operating  expenses to acquire,  permit and develop a gold property in
California  which is held  through  Sutter Gold Mining  Company  ("SGMC").  This
investment  represents  a  significant  portion  of USE's  consolidated  assets.
Although  SGMC  completed  private  financings  in  fiscal  1997  for a total of
$7,115,100,  additional financing will be required to put the property into full
production and build a mill on the property.  If third-party financing cannot be
obtained and USE is unable to fund SGMC's  development and production costs from
internally  generated funds, USE may be adversely affected.  In fiscal 1998, USE
recorded  an  impairment  of $1.5  million on its  investment  in SGMC;  further
impairments  may have to be recorded  during the  remainder of fiscal 1999.  See
"Information  About USE -  Business  and  Properties  - Gold -  Lincoln  Project
(California)".

         3.  Additional  Shares  to  Market;  Possible  Dilution.  USE may issue
additional  common stock in a private  placement or a public  offering if needed
for development capital (see Risk Factor 1 above).

         In addition, USE and Crested may finance the development of the uranium
assets  through a new entity.  The new entity would hold the  principal  uranium
assets  of USE  and  Crested,  and  USE  and  Crested  would  be  the  principal
shareholders  of the new  entity.  The  impact  of such a  restructuring  on the
shareholders of USE and Crested will not be known until terms of the transaction
have been finalized.

         4.  Variable  Revenues  and Recent  Losses.  Due to the nature of USE's
business,  there are from time to time major  changes in  revenues  from sale of
mineral properties or otherwise.  During fiscal 1991,  $7,193,600 was recognized
from sale of a partial  interest  in a uranium  property  to  Kennecott  Uranium
Company (a GMMV partner).  No similar  revenues were recognized from fiscal 1992
through fiscal 1995. USE realized net income in fiscal 1992 of $613,000, but net
losses were  realized  from fiscal 1993 through  fiscal 1995 (in the  respective
amounts of $221,900,  $3,370,800 and  $2,070,600).  Revenues in fiscal 1997 were
$5,790,200, compared to $9,632,200 in 1996. The decrease was primarily due to no
revenues  being  recognized  from mineral sales in 1997. In 1996,  USE had a net
profit of  $270,700,  but  realized a net loss in 1997 of  $3,724,500.  In 1998,
revenues were $11,558,500 but USE lost $983,200.

         5. Limited  Number of Customers for Uranium.  The worldwide  market for
uranium is marked by few buyers,  aside from governments which buy uranium oxide
for navy vessels and weapons  manufacture,  and an immaterial amount consumed by
the medical sector.  There are approximately 18 electric utilities in the United
States (and 97 more in the rest of the world),  which operate  nuclear  reactors
(108 reactors in the United  States,  331 in the rest of the world).  Therefore,
the number of potential customers for USE's uranium at any one time is likely to
be very limited.

                                       10

<PAGE>



         6. Public  Resistance to Nuclear  Energy.  In the late 1970s,  a safety
system  failure  at  a  nuclear  reactor  located  at  the  Three  Mile  Island,
Pennsylvania  generating  station resulted in an incident which decreased public
acceptance of nuclear-powered electricity. Because of this incident, the Nuclear
Regulatory  Commission  ("NRC")  adopted and imposed new safety  regulations  on
electric  utilities  which used nuclear  power.  A number of reactors which then
were in the  planning  or  construction  phases were  canceled  by the  domestic
utility industry.  Another nuclear reactor safety incident could again adversely
affect public  acceptance of nuclear power in the United  States,  and result in
more regulations, which might cause some utilities to cut back on their plans to
continue  operating nuclear reactors or cancel plans to build new reactors.  Any
decrease in the number of  operating  and/or  planned  reactors  might  decrease
future  demand  and prices  for  uranium  oxide.  See  "Information  About USE -
Business and Properties - Uranium Market Information."

         7. Project  Delay.  USE's  minerals  business is subject to the risk of
unanticipated delays in developing and permitting its uranium and gold projects.
Such delays may be caused by fluctuations  in commodity  prices (see Risk Factor
9), mining risks (see Risk Factor 12), difficulty in arranging needed financing,
unanticipated  permitting  requirements,  or legal obstruction in the permitting
process by project  opponents.  In addition to increasing  project capital costs
(and possibly  operating costs),  extended delays could result in a write off of
all or a portion  of USE's  investment  in the  delayed  project,  and/or  could
trigger certain reclamation obligations sooner than planned.

         8. Debt. At May 31, 1998 USE had $278,200 of long-term  debt  ($503,900
including  the current  portion of $225,700),  and a $1,000,000  secured line of
credit from a commercial bank (with interest at the bank's prime rate plus .5%).
The $1,000,000  line of credit has expired,  but USE presently is negotiating to
obtain a new bank line of credit for  $2,500,000.  At November 30, 1998, USE had
$203,700 of long-term debt ($544,200 including the current portion of $340,500).
The amount of debt is small  relative  to USE's  financial  condition.  However,
because of estimated  reclamation  obligations  and standby costs of $13,055,600
(at May 31, 1998), USE may have a limited  borrowing base and therefore could be
unable  to  borrow  significant  amounts  of  money  if  the  need  arises.  For
information on the reclamation obligations and standby costs, see Risk Factor 14
and "Note K to the USE Consolidated Financial Statements."

         9.  Commodity  Price  Fluctuations.  The  ability of USE to develop and
operate its uranium and gold projects profitably will be significantly  affected
by changes in the market  price of uranium and gold.  From 1988 until  mid-1996,
the spot market price for uranium concentrates (U3O8) was depressed and had been
below $8.00 per pound as recently as 1992. See "Information About USE - Business
and Properties Uranium - Uranium Market Information." Uranium prices are subject
to a number of factors  beyond the control of USE  including  imports of uranium
from  Russia and other  countries  in the  Commonwealth  of  Independent  States
("CIS"),  the amount of uranium  produced  and sold from the  blending of highly
enriched  uranium  recovered from U. S. and Russian  nuclear  weapons to produce
lower  enriched  uranium for nuclear fuel,  the build up by utilities of uranium
fuel inventories and the sale of excess inventories into the market, the rate of
uranium  production  in the United  States,  Canada,  Australia and elsewhere by
other  producers  and  the  rate  of  new  construction  of  nuclear  generating
facilities,  versus the rate of shutdown and  decommissioning  of older  nuclear
generating facilities, particularly in the United States.

         Market  prices  for  uranium  concentrates  U3O8 in the  United  States
recovered to between  $16.25 and $16.50 per pound as of May 31,  1996,  however,
prices were between $10.30 and $14.80 per pound in fiscal 1997. The market price
at  January  19,  1999 was  $10.00 per  pound.  USE  believes  that if the price
increases  substantially,  more utilities will seek long term price  stabilizing
uranium  supply  contracts.  If USE is able to obtain long term  uranium  supply
contracts with assured prices  exceeding its cost of production,  then Plateau's
and GMMV's  properties  will be  profitable.  USE estimates  that its production
costs will be comparable to the production  costs of the more efficient  uranium
mines and mills now in  operation,  primarily  because the mine and mill capital
costs  have been paid for by  others.  USE would be  adversely  affected  if the
United  States  utilities  with nuclear  power plants do not seek more long term
uranium supply contracts by the end of calendar

                                       11

<PAGE>



2000. Although the extent of such adverse impact cannot be predicted, if uranium
prices  remained so depressed  through  calendar 2000 that USE's  properties and
facilities were not put into operation,  the economic value of such assets might
decrease.

         The  market  price of gold has  fluctuated  widely and is  affected  by
numerous factors beyond USE's control,  including international economic trends,
currency  exchange  fluctuations,  the  extent  of  forward  sales  of  gold  by
producers,  consumption  patterns  (gold jewelry and gold coins),  purchases and
sales of gold  bullion  holdings by central  banks or other  large gold  bullion
holders or dealers and global or regional  political events.  Gold market prices
are also  affected by worldwide  production  levels,  which  increased in recent
years,  but currently are decreasing.  The aggregate  effect of these factors is
impossible to predict at any one time.  As of February 12, 1999,  the Comex spot
price of gold was $290.50 per ounce,  compared to $373 per ounce on November 24,
1996.

         10. Proposed Federal  Legislation.  In recent years, the U.S.  Congress
has considered  several  proposals for major revisions of the General Mining Law
of 1872,  which governs  mining claims and related  activities on federal public
lands. If any of the proposals  become law, it could result in the imposition of
a royalty upon  production of minerals  from federal lands and new  requirements
for mined land reclamation and other environmental  control measures. It remains
unclear whether Congress will pass such legislation.  The effect of any revision
of the  General  Mining  Law of 1872 on USE's  operations  cannot be  determined
conclusively  until such revision is enacted;  however,  such legislation  could
materially  increase  the  carrying  costs of the uranium  properties  which are
located on federal unpatented mining claims, and could increase both the capital
and operating costs for such projects.

         11.  Exploration  Risks.  Mineral  exploration,  particularly for gold,
involves many risks and frequently is nonproductive.  Efforts at the Sutter Gold
Mine to identify  additional gold ore reserves may not be successful.  Moreover,
substantial  expenditures  are  required to  establish  additional  ore reserves
through  drilling and build mining and  processing  facilities.  During the time
required to establish additional reserves and construct facilities, the economic
feasibility of production  may change  because of  fluctuating  gold prices (see
Risk Factor 9).

         12. Mining Risks and Insurance. The business of uranium and gold mining
generally is subject to a number of risks and hazards,  including  environmental
hazards, industrial accidents, explosions and rock falls, earthquakes, flooding,
interruptions due to weather  conditions and other acts of God. Such risks could
result in damage to or  destruction  of USE's mineral  properties and production
facilities,  as well as to  properties of others in the area,  personal  injury,
environmental damage and process and production delays,  causing monetary losses
and possible legal  liability.  While USE maintains,  and intends to continue to
maintain,  liability,  property  damage  and  other  insurance  consistent  with
industry  practice,  no  assurance  can be given that  adequate  insurance  will
continue to be available.

         USE carries property damage insurance with claim limits of $10,000,000.

         13. Title to Properties.  Nearly all the uranium mining properties held
by USE, GMMV and Plateau are on federal unpatented claims. Unpatented claims are
located upon  federal  public land  pursuant to  procedures  established  by the
General Mining Law of 1872. Title to such properties can be challenged. Although
there now are no challenges to USE's title rights, such challenges in the future
could  jeopardize  title and possibly cause delays in operations on the affected
properties.  See "Information About USE - Business and Properties - Mining Claim
Holdings."

         14.  Reclamation  and  Environmental  Liabilities.  USE's  projects and
operations are subject to various federal,  state and local laws and regulations
regarding the discharge of materials into the environment or otherwise  relating
to the  protection  of the  environment,  including the Clean Air Act, the Clean
Water Act,

                                       12

<PAGE>



the Resource  Conservation and Recovery Act and the Comprehensive  Environmental
Response Compensation Liability Act. With respect to mining operations conducted
in Wyoming, the mine permitting statutes, the Abandoned Mine Reclamation Act and
industrial  development and siting laws and regulations will impact USE. Similar
laws in  California  affect SGMC  operations  and in Utah will affect  Plateau's
operations. In addition, USE's uranium mill in Utah and the GMMV mill in Wyoming
are subject to jurisdiction of the Nuclear Regulatory Commission ("NRC").

         To the knowledge of USE, it is in  compliance in all material  respects
with current environmental regulations. To the extent that production by GMMV or
SGMC is delayed,  interrupted or discontinued  due to need to satisfy present or
any future laws or regulations which relate to environmental protection,  future
USE earnings could be adversely affected.  For additional information concerning
the  effect  such  environmental  laws and  regulations  have on  USE's  capital
expenditures,   see   "Information   About  USE   Business   and   Properties  -
Environmental" and "Notes F and K to USE's Consolidated Financial Statements."

         15.  Possible  Losses on Uranium  Contracts.  USE holds a contract  for
delivery of U3O8 to a domestic utility through 2000,  exclusive of the utility's
rights to increase or decrease  delivery amounts by 10 to 30 percent.  Profit or
loss on the deliveries will depend on the cost of inventory.

         As of the date of this Prospectus, the prices under the contract exceed
the current market price, however, there can be no assurance this situation will
not change in the  future.  Increases  in the spot market  price would  increase
USE's and Crested's  cost of  delivering on the contract  prior to the time that
their uranium  properties are in production,  thus reducing potential profits or
possibly producing losses.

         16.  Competition.  There is keen  competition in the domestic  minerals
industry for properties and capital. USE's competitors include a number of major
mining  companies,  most of which are larger  than USE in all  respects.  In the
production  and marketing of uranium  concentrates  there are more than 10 major
international  entities  (some  of which  are  government  controlled)  that are
significantly larger and better capitalized than USE.

         The  location  and  composition  of  mineral  ore  bodies  are of great
importance  to the  competitive  position  of a  mining  company.  Producers  of
high-grade  ore  with  readily  extractable  minerals  are  in  an  advantageous
position.  Producers  of one mineral may be able to  efficiently  recover  other
minerals  as  by-products,   with  significant  competitive  impact  on  primary
producers.  Substantial  capital costs for equipment  and  mine-works  are often
needed. As a result,  owners of producing  properties,  particularly if purchase
contracts  for  the  production  are  in  place,   generally  enjoy  substantial
competitive  advantages over organizations that propose to develop non-producing
properties.  Competition  is also keen in the search for mineral  properties and
prospects and in the employment and retention of qualified personnel.

         USE expects competition from larger producers in Canada,  Australia and
Africa,  as well as from U.S. in situ  producers of uranium and other  producers
that recover uranium as a byproduct of other mineral recovery  processes.  There
also is  competition  from uranium  recovered from the  de-enrichment  of highly
enriched  uranium  obtained from the  dismantlement  of U.S. and Russian nuclear
weapons and sold in the market by USEC Inc. and/or the United States  Department
of Energy,  as well as from  imports to the  United  States of uranium  from the
Commonwealth of Independent States (formerly the Soviet Union). See "Information
About USE- Business and Properties - Uranium - Uranium Market  Information"  and
"NUEXCO Exchange Value".

         17.  Estimates of Mineralized  Materials.  The estimates of mineralized
resources  at the GMMV's  Round Park  uranium  ore deposit in Wyoming and SGMC's
gold  property in  California  have been  reviewed by  independent  consultants.
However,  such estimates are necessarily  imprecise and depend to some extent on
statistical  inferences  from limited  sampling  results which may, on occasion,
prove unreliable.

                                       13

<PAGE>



Should  USE  encounter  mineralization  or  formations  at any of its  mines  or
projects  different from those  predicted by drilling and similar  examinations,
those  estimates may have to be adjusted and mining plans may have to be altered
in a way that could adversely affect USE's operations.

         18. Bullfrog Litigation. USE and Crested are defendants and counter- or
cross-claimants  in certain  litigation  in the  District  Court of Nye  County,
Nevada,  brought by Bond Gold  Bullfrog  Inc.  ("BGBI") in July 1991.  BGBI (now
known as Barrick  Bullfrog,  Inc.) is an  affiliate  of Barrick  Corp.,  a large
international  gold producer  headquartered in Toronto,  Canada.  The litigation
primarily  concerns  extralateral  rights  associated  with two patented  mining
claims.

         If USE's  and  Crested's  position  concerning  extralateral  rights is
ultimately sustained, substantial additional revenues and income may be received
from  royalties on the gold produced from the Bullfrog Mine.  If,  however,  the
final decision in this litigation is adverse to USE and Crested, USE and Crested
could be adversely affected. See "Information About USE - Legal Proceedings."

         19.  Potential  Issuance of  Preferred  Stock.  Under the USE  Restated
Articles of Incorporation,  as amended ("Restated Articles") and as permitted by
the Wyoming Business Corporation Act ("WBCA"), the Board of Directors of USE has
authority  to create one or more series of  preferred  stock and to issue shares
thereof, without the approval of any USE shareholders. The creation and issue of
USE  preferred  stock with  dividend  rights  senior to USE's Common Stock could
adversely  affect common  stockholder  participation  in future earnings through
dividends that otherwise  would be available for  distribution to holders of the
Common Stock.

         Such  preferred  stock also could inhibit a takeover of USE.  Under the
WBCA,  separate  voting  approval  by classes of stock is  required  for certain
substantive corporate  transactions.  If the interests of preferred stockholders
is  perceived  to be  different  from  those  of the  common  stockholders,  the
preferred  stockholders  could withhold  approval of the transactions  needed to
effect the takeover.

         20. Potential  Anti-Takeover Effects of Staggered Board. USE's Board of
Directors is presently  divided into classes.  Pursuant to the Restated Articles
and as  permitted  by the WBCA,  the  directors in each class serve a three year
term, and only those  directors in one class are reelected each year. This board
classification  could stall a takeover of USE,  even if a majority of the Common
Stock were to be held by persons  desiring a change in control of the Board. See
"Description of Securities."

                           TERMS OF THE EXCHANGE OFFER

         General. This Exchange Offer is made pursuant to the September 17, 1997
Exchange  Rights  Agreement  between USE, YSFC and AFFC.  This Exchange Offer is
made by USE to each of the YSFC  shareholders  who invested in YSFC through AFFC
in late 1997 and early 1998. Each such YSFC shareholder may exchange some or all
the YSFC shares  owned for shares of USE Common  Stock until the  expiration  of
this Exchange  Offer at 5:00 pm MST on September 22, 1999.  This Exchange  Offer
also is made by USE to each holder of the YSFC  Warrants,  who may exchange some
or all of the YSFC Warrants for USE Warrants.  Shareholders  of YSFC who did not
invest in YSFC through AFFC cannot participate in this Exchange Offer.

         The Exchange Rights Agreement was intended to provide  liquidity to the
YSFC shareholders  (and the holders of the YSFC Warrants),  by allowing them the
opportunity  to  exchange  their  securities  in a private  company  (YSFC)  for
securities in a Nasdaq NMS public company (USE).  The Exchange Rights  Agreement
was  negotiated  at arms'  length  between  YSFC,  USE  (which had  founded  and
organized  YSFC and owns a  substantial  number  of YSFC  shares),  and AFFC (as
YSFC's placement agent in the private offering of YSFC restricted shares). Under
the  Exchange  Rights  Agreement,  if YSFC were not  listed on Nasdaq NMS by the
eighteenth  month  anniversary of the Exchange  Rights  Agreement,  USE would be
required at that time to make

                                       14

<PAGE>



an offer to the YSFC  shareholders to exchange free trading shares of USE Common
Stock for their  restricted  shares of YSFC.  An  initial  listing on Nasdaq NMS
would  require YSFC to meet several  conditions,  including  having  minimum net
tangible assets of $6,000,000 and at least 400 shareholders.  YSFC does not meet
these conditions to listing (and does not anticipate meeting these conditions in
1999 or  2000).  Therefore,  this  Exchange  Offer  is  being  made to the  YSFC
shareholders  and holders of the YSFC Warrants  pursuant to the Exchange  Rights
Agreement.

         The basic terms of the Exchange  Rights  Agreement were approved by the
USE board of directors at a special  meeting of the directors of USE and Crested
on August 19, 1997. At that meeting,  the directors of USE and Crested discussed
the various  basic terms of the Exchange  Rights  Agreement as proposed by AFFC,
the  funding of YSFC  through  that date by USE and  Crested  and other  factors
including  USE share  value in August  1997.  The  directors  of USE and Crested
discussed  the  difficulties  which  had been  encountered  in  trying to obtain
funding for YSFC before,  and they  discussed the amount of funding to be raised
for YSFC by AFFC. At that meeting USE and Crested  authorized John L. Larsen and
Max T. Evans, directors of USE and Crested,  respectively,  and Daniel P. Svilar
(general  counsel to both  companies)  and R.  Scott  Lorimer  (chief  financial
officer for both  companies)  to  negotiate  with AFFC to include a cost sharing
provision in the Exchange  Rights  Agreement,  and to execute such  Agreement on
behalf of USE and Crested.  AFFC did not agree to the cost sharing proposal (ie.
to pay any of the costs of this  Prospectus).  The Exchange Rights Agreement was
executed by all parties on September 17, 1997.

         Exchange  Ratio - Shares.  The Exchange  Ratio for shares is based upon
(x) the original  investment amount paid by the YSFC shareholder plus 10 percent
simple annual interest, divided by (y) the average of the closing Nasdaq NMS bid
prices  for a share of USE Common  Stock for the five  trading  days  before USE
receives  the Notice of  Election to Exchange  from each YSFC  shareholder.  The
average price for USE Common Stock is referred to in this Prospectus as the "USE
share value." No fractional  USE shares will be issued;  any  fractional  shares
will be rounded up to the next full USE share.

         As an example of how the Exchange Offer to YSFC  shareholders  might be
applied,  USE would issue 5,813  shares to a YSFC  shareholder  who bought 5,000
shares of YSFC on October 16, 1997, and through this Exchange Offer,  elected to
exchange  all of his or her YSFC  shares  for USE  shares and sent the Notice of
Election  to Exchange to USE on June 1, 1999 when the USE share value is assumed
to be $2.00.

           Example of How the Exchange Ratio for Shares Is Calculated

                            Total               USE              Number of USE
  Invested Amount        Interest(1)        Share Value        Shares Exchanged
  ---------------        -----------        -----------        ----------------

    $10,000.00            $1,624.94            $2.00             5,813 Shares

         (1) Interest is calculated at $83.33 per month for this example  (based
on 10 percent  per year on the  $10,000.00  investment,  divided by 12  months);
interest accrues for the 19.5 months from October 16, 1997 to June 1, 1999.

         Exchange Ratio - Warrants.  The Exchange Ratio for warrants is based on
(x) the number of YSFC shares  underlying the holder's YSFC Warrants  multiplied
by  $2.00,  divided  by (y) the  USE  share  value.  The  USE  Warrants  will be
exercisable until September 19, 2002 (the original term of the YSFC Warrants) at
an  exercise  price per USE share  which is equal to the USE  share  value.  See
"Description of USE Securities."

         As an example  of how the  Exchange  Offer to holders of YSFC  Warrants
might be applied,  USE would issue USE Warrants to purchase 16,254 USE shares to
a holder of YSFC  Warrants who elected to exchange  YSFC  Warrants  when the USE
share value is assumed to be $2.00.

         USE  will  pay  all of the  costs  of the  Exchange  Offer  (legal  and
accounting  fees,  and  printing and mailing  costs),  which are related to this
Prospectus and the registration  statement which includes this  Prospectus.  USE
will  not pay any  commissions  on  resale  of the USE  shares  or USE  Warrants
acquired by YSFC  shareholders  or holders of YSFC  Warrants  under the Exchange
Offer.

Plan of Distribution.

         The USE  shares  will be  offered  for sale by the  holders  of the USE
shares and Warrants  acquired in this Exchange  Offer at market prices from time
to time. Selling commissions will be paid by such persons.
No sales proceeds will be paid to USE or any subsidiary of USE.

         The USE shares  and  Warrants  may be offered  from time to time (i) in
transactions  in  the  Nasdaq  NMS   over-the-counter   market,   in  negotiated
transactions or a combination of such methods of sale, and (ii) at market prices
prevailing  at the time of sale,  at prices  related to such  prevailing  market
prices,  or at  negotiated  prices.  Such  persons may effect such  transactions
directly with the broker-dealers.  Such broker-dealers may receive  compensation
in the form of discounts,  concessions or  commissions  from the sellers for who
they may act as agents or the  persons  to who they may sell as  principals,  or
both (which compensation as to a particular  broker-dealer might be in excess of
customary  commissions).  Sales of the  securities  may be made pursuant to this
Prospectus or pursuant to Rule 144 adopted under the 1933 Act.

         No underwriting  arrangements  exist as of the date of this Prospectus.
Upon being advised of any underwriting  arrangements that may be entered into by
the holders of the USE shares or Warrants after the date of this Prospectus, USE
will prepare and file a post-effective  amendment to this Registration Statement
including  a  supplement  to  this  Prospectus  to  disclose  the  name  of such
underwriters and such arrangements.

         USE is paying the expenses  estimated at $10,000 of registering the USE
securities under the 933 Act.

         How to Participate in the Exchange Offer. If you want to participate in
the  Exchange  Offer,  you must  complete  and sign the  Notice of  Election  to
Exchange (included with this Prospectus),  and send it to USE together with your
certificates  for YSFC shares (and a signed stock power) or your YSFC  Warrants.
Your stock power must be stamped  guaranteed  by a bank or brokerage  firm which
participates in the Medallion stamp program.

         Your Notice of Election to Exchange will be  irrevocable  once received
and  accepted by USE. You are entitled to only one  election;  however,  you may
exchange some or all of your YSFC securities at that time. USE will issue shares
of Common Stock and YSFC Warrants to the  participating  YSFC  shareholders  and
holders of the YSFC  Warrants,  based on the USE share value in effect when your
Notice of Election to Exchange is received, and, in the case of YSFC shares, the
amount  of  interest  which  has  accrued.  Please  allow  at  least 10 days for
processing  and  mailing  certificates  for USE  shares to you.  Along with your
certificates,  you will receive a  computation  of the Exchange  Ratio which was
applied to your YSFC securities.

         The Notice of Election to Exchange and other documents must be received
at USE on or before  September  22, 1999. No Notice of Election to Exchange will
be accepted after September 22, 1999.

         The Exchange Rights Agreement is included in this Prospectus.

Federal Income Tax Consequences of the Exchange Offer.

         The  Exchange  Offer is not a "tax  free"  transaction.  The  following
summary  is  intended  to  highlight  the  most  important  federal  income  tax
consequences  of the Exchange  Offer for  participating  YSFC  shareholders.  It
should be noted  that USE has not  obtained  any legal  opinion  concerning  the
federal income tax consequences of the Exchange Offer for YSFC  shareholders who
participate in the Exchange Offer. In addition, the summary does not discuss the
tax  consequences  for holders of YSFC Warrants who  participate in the Exchange
Offer.  YSFC  shareholders and the holders of YSFC Warrants should consult their
own tax advisors to determine the federal (and state) income tax consequences of
participating in the Exchange Offer.

         In general,  a participating  YSFC shareholder will acquire most of his
or her USE shares with a basis (for income tax  purposes)  equal to the original
investment in YSFC shares ($2.00 per share). If a participating YSFC shareholder
holds the USE shares received in the Exchange Offer for more than 12 months, any
gain or loss  realized on sale  thereafter  will be treated as capital  gains or
losses under the Internal Revenue Code of 1986, as amended (the "IRC"),  using a
basis of $2.00 per USE share.

         In  addition,  the USE shares  received  in  payment of the  accrued 10
percent  annual  interest  on  the  original  investment  in  YSFC  shares  will
constitute  ordinary  income under the IRC; the income will be deemed  earned in
the calendar year of receipt, and the tax will be due in the following year. The
amount  of  income  will  be  equal  to  the  market  value  of the  USE  shares
representing payment of that interest amount.

                          DESCRIPTION OF USE SECURITIES

         The USE  Restated  Articles  of  Incorporation  authorize  issuance  of
20,000,000  shares  of Common  Stock,  $.01 par  value,  and  100,000  shares of
preferred stock, $.01 par value.

         Common Stock. Holders of Common Stock are entitled to receive dividends
when and as declared by the Board of Directors  out of funds  legally  available
therefor.

         Holders  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 to the USE Board of Directors.
Cumulation  is  effected  by  multiplication  of  shares  held by the  number of
director  nominees,  and voting is by casting the  product as desired  among the
nominees; directors are elected by a plurality of votes cast.

         Pursuant  to the  Restated  Articles of  Incorporation  and the Wyoming
Management  Stability  Act,  shares  of USE  Common  Stock  held  by  affiliated
companies (Crested,  Plateau and SGMC) may be voted by such affiliated companies
in elections of USE directors,  so long as USE conducts  substantial business in
Wyoming  and is  "qualified"  under  such Act as  having  assets  in  excess  of
$10,000,000, with a class of stock listed on Nasdaq or on a principal exchange.

         In the event of dissolution,  liquidation or winding up of USE, holders
of  Common  Stock are  entitled  to share  ratably  in  assets  remaining  after
creditors   (including  holders  of  any  preferred  stock,  as  to  liquidation
preferences) have been paid.

         All  outstanding  shares of Common  Stock and the  shares of USE Common
Stock to be issued in the Exchange  Offer will be, when  issued,  fully paid and
nonassessable.


                                       17

<PAGE>



         Preferred  Stock.  The USE Board of  Directors is  authorized  to issue
shares of preferred stock in one or more series, with such rights to redemption,
liquidation preference, dividends, voting and other matters as determined by the
Board  of  Directors,   without   authorization   from  the  USE   stockholders.
Accordingly,  the USE Board of  Directors  could  issue  preferred  shares  with
dividend  rights  senior  to  the  Common  Stock.  Under  the  Wyoming  Business
Corporation  Act,  separate  classes of stock are entitled to vote separately on
certain  substantive  transactions  (e.g.,  a merger  or sale of most of the USE
assets), with approval of the transaction subject to approval by each class.

         No shares  of USE  preferred  stock  have  been  issued,  and no series
thereof has been established to date.

         Warrant to Shamrock Partners, Ltd. On January 20, 1998 USE entered into
a nonexclusive one year Investment  Banking  Consulting  Agreement with Shamrock
Partners,  Ltd. ("SPL"), 111 Veterans Square, Media,  Pennsylvania,  under which
SPL is to provide financial consulting services and advice concerning financing,
merger  and  acquisition  proposals,  and to assist  USE in  arranging  meetings
between  representatives  of USE and financial  institutions  in the  investment
community  (including  broker-dealer  firms,  security  analysts,  and portfolio
managers).  For  SPL's  services,  as of  December  5, 1997 USE  authorized  the
issuance to SPL a Warrant to Purchase 200,000 shares of Common Stock of USE at a
price of $6.00 cash per share;  the Warrant is exercisable  through  January 20,
2000. The Holder (or substitute Holders) of the Warrants are not entitled to any
rights of a shareholder in USE by virtue of holding the Warrants.

         The Warrant carries certain rights of registration  with the Commission
under the 1933 Act as more specifically described in the Warrant. If the Company
so registers the Warrants solely to accommodate the registration for public sale
of the underlying  200,000 Warrant Shares, the Holder or Holders of the Warrants
may not sell or otherwise  transfer the Warrants for a period of 24 months after
the effective date of such registration statement, which period prevents sale or
transfer of the Warrants prior to their Expiration Date.

         As of the date of this  Prospectus,  SPL has not exercised the Warrant,
and USE has not filed a  registration  statement for SPL in connection  with the
Warrant.  This  Prospectus does not include such Warrant or any shares of Common
Stock issuable on its exercise.

         Warrant to Sunrise  Financial  Group,  Inc. As of December 1, 1997, USE
retained  Sunrise  Financial  Group,  Inc.  ("Sunrise")  to serve as a financial
consultant and advisor on a nonexclusive  basis until December 1, 1998.  Sunrise
provided a limited amount of services and advice  pertaining to USE's  business.
As compensation for Sunrise's services,  in December 1997, USE issued to Sunrise
a Warrant to Purchase 225,000 shares of Common Stock; the Warrant is exercisable
until December 1, 2000 at $10.50 per share. Sunrise has the right to demand that
USE  register  the  purchased  shares  for sale to the public  through  filing a
registration  statement with the Commission.  As of the date of this Prospectus,
Sunrise has not exercised  the Warrant.  This  Prospectus  does not include such
Warrant or any shares of Common Stock issuable on exercise of such Warrant.

         Share Option to R.J. Falkner & Company.  In February 1999, USE retained
R.J.  Falkner & Company  ("RJF") for  shareholder  relations and stock brokerage
communication  services  for one year.  USE will pay RJF $2,000 per month,  plus
expenses,  and will grant a three year option to R. Jerry Falkner,  an affiliate
of RJF, to purchase  20,000 shares of  restricted  USE shares of Common Stock at
$2.62 per share until  February 1, 2002.  USE will  register the exercise of the
options and resale of the USE shares  purchased on exercise with the Commission,
by including the securities in another  registration  statement filed by USE, or
at Mr. Falkner's request, made at any time before February 1, 2001.

         USE Warrants.  On September 19, 1997, YSFC issued YSFC Warrants to AFFC
and three  individuals  associated with AFFC,  pursuant to the Agency  Agreement
between  AFFC and YSFC by which AFFC,  acting as YSFC's  placement  agent,  sold
shares of restricted Common Stock of YSFC to customers of

                                       18

<PAGE>



AFFC. The YSFC Warrants are exercisable at any time during the four years ending
September  19, 2002,  to purchase an aggregate of 121,900  shares of  restricted
Common Stock of YSFC at a price of $2.00 per share. Pursuant to the terms of the
YSFC  Warrants,  YSFC  shares  may  be  purchased  for  cash,  or in a  cashless
transaction  by YSFC  issuing  YSFC shares in number equal to result of dividing
(x) the market  value of the  underlying  shares less  $2.00,  by (y) the market
value of the underlying  share,  then (z) multiplying the resulting  fraction by
the number of YSFC shares issuable on exercise of the holder's YSFC Warrant. The
cashless  exercise method would reduce the number of shares issuable on exercise
of the YSFC  Warrants,  but would not result in any cash proceeds being received
by YSFC.

         The YSFC Warrants contain  anti-dilution  provisions which would adjust
the  exercise  price of the  Warrants in the event YSFC were to issue shares for
consideration which is less than the $2.00 exercise price of the Warrants. These
provisions  will  continue  to be  available  to  holders of YSFC  Warrants  who
participate in this Exchange  Offer.  The USE Warrants  issued to  participating
holders of the YSFC  Warrants  will contain  similar  anti-dilution  provisions,
which would adjust the exercise price of the USE Warrants as necessary after the
holder's Notice of Election to Exchange is received by USE.

         USE  Warrants  issued  to the  holders  of YSFC  Warrants  who elect to
participate in this Exchange Offer will have terms identical to the terms of the
YSFC Warrants, except that the exercise price for the USE Warrants will be equal
to the USE share value determined on the date the holder's Notice of Election to
Exchange is received by USE.

         Comparison  of the  Rights of Holders  of  Securities  of YSFC and USE.
There are no material  differences between the rights of holders of Common Stock
of YSFC,  and the rights of holders of Common Stock of USE or between the rights
of holders of YSFC Warrants and the rights under the USE Warrants.

         Accounting  Treatment of the Exchange  Offer.  Assuming all of the YSFC
shares and YSFC Warrants are exchanged for USE shares and USE Warrants  pursuant
to this Exchange  Offer,  the accounting  treatment of the Exchange Offer by USE
will be as follows:

         If  all of  the  YSFC  shares  are  exchanged  for  USE  shares,  USE's
percentage ownership of YSFC will increase from its current 25.6 percent to 36.0
percent  (38 percent if YSFC  converts  the debt owed to USE and Crested to YSFC
shares, see "Information About YSFC"). As a result of USE's increased  ownership
in YSFC, a greater  percentage of the equity in YSFC's operating results will be
included  in  USE's  operating  results,  and  reflected  in the  USE  financial
statements  on a quarterly  and annual  basis.  In addition,  as a result of the
shares  exchanged under this Exchange Offer, a greater number of USE shares will
be stated as outstanding on the USE balance sheets.  However, USE will not own a
majority of the YSFC shares, and therefore YSFC's financial  statements will not
be consolidated into the USE financial statements.

         Except for summary  information,  this  Prospectus does not include pro
forma financial information (which would show financial information about USE as
if the Exchange  Offer were  completed  as of May 31,  1998,  the 12 months then
ended,  and the six months ended November 30, 1998),  because after the Exchange
Offer (i) YSFC will remain a minority  subsidiary  of USE, and (ii) the increase
in equity  ownership by USE in YSFC as a result of the Exchange  Offer would not
have  materially  affected  USE's  operating  results on a pro forma basis.  See
"Summary of the Offering - Selected  Financial  Data - Selected  Historical  and
Unaudited Pro Forma Per Share Financial Data" above.

         The Exchange  Offer will effect a percentage  dilution to the ownership
of USE by its current shareholders. If the USE share value in effect at the date
of this  Prospectus  remains at $2.00  throughout the Exchange  Offer,  the YSFC
shareholders  could  acquire up to 15.85 percent of USE.  This  percentage  will
decrease  or  increase  depending  on (i) the  number  of YSFC  shares  actually
exchanged,  and (ii) USE share  values in effect  from time to time  during  the
Exchange Offer. In addition, there will be dilution in the per

                                       19

<PAGE>



share net tangible book value of the USE shares presently  outstanding ($1.87 at
November 30, 1998 before the Exchange Offer, $1.89 at November 30, 1998 on a pro
forma basis assuming the Exchange Offer were  consummated for all YSFC shares as
of that date and a USE share value of $2.00).

                    Information About the Holders of Warrants

         The number of YSFC Warrants,  and the number of USE shares owned by the
holders of the YSFC  Warrants  after the  Exchange  Offering  shown in the table
below.  None of the  holders  has had any  position  or served as an  officer or
director  of YSFC or USE or any other  company  affiliated  with  USE.  American
Fronteer Financial  Corporation acted as placement agent for a private financing
of YSFC in 1997.  The  individual  holders  Robert L. Long,  John P. Kanouff and
Robert H. Taggart, Jr. still are associated with AFFC.

BUSINESS AND PROPERTIES

Minerals - Uranium

         General.  USE has  interests in several  uranium-bearing  properties in
Wyoming and Utah and in uranium processing mills in Sweetwater  County,  Wyoming
(the  "Sweetwater  Mill")  and  in  southeastern   Garfield  County,  Utah  (the
"Shootaring  Mill").  All the  uranium-bearing  properties  are in  areas  which
produced  significant  amounts of  uranium in the 1970s and 1980s.  USE plans to
develop and operate these properties  (directly or through a subsidiary  company
or a joint venture) to produce uranium concentrates  ("U3O8") for sale to public
utilities  that  operate  nuclear  powered  electricity  generating  plants.  In
addition, other uranium-bearing properties in New Mexico and Wyoming are held by
Yellow Stone Fuels Corp. (a minority joint subsidiary of USE and Crested).

         The property interests of USE in Wyoming are:

         Green Mountain

         521  unpatented  lode mining  claims (the "Green  Mountain  Claims") on
Green  Mountain in Fremont  County,  Wyoming,  including 105 claims on which the
Round Park  (Jackpot)  uranium  deposit is  located,  and the  Sweetwater  Mill,
(approximately  23 miles south of the proposed  Jackpot Mine).  These assets are
held by the Green Mountain Mining Venture ("GMMV"),  owned 50 percent by USE and
USECC (the "USE Parties"), and 50 percent by Kennecott Uranium Company ("KUC" or
"Kennecott"), a subsidiary of Kennecott Energy and Coal Company of Gillette, WY.
Kennecott Energy and Coal Company is a subsidiary of Rio Tinto plc, formerly RTZ
plc of London.  Rio Tinto plc is one of the  world's  leading  natural  resource
companies and

                                       20

<PAGE>



owns 69% of Rossing Uranium Corp.'s  operations in Namibia in southwest  Africa.
Rossing  currently  produces about  6,000,000 lbs. of U3O8 of its 10,000,000 lb.
annual  capacity.  Rio Tinto has delayed  indefinitely  the  construction of its
4,000,000 lb. U3O8 per year Kintyre uranium project in Western Australia.

         All of the GMMV mining claims are accessible by county,  private and/or
United States Bureau of Land  Management  ("BLM") access roads.  Exploration and
delineation of the principal uranium resources in the proposed Jackpot Mine have
been substantially  completed. The BLM has signed a Record of Decision approving
the  Jackpot  Mine  Plan  of  Operations   following   preparation  of  a  final
Environmental  Impact  Statement  ("EIS") for the proposed mine, and on June 25,
1996,  the Wyoming  Department of  Environmental  Quality  ("WDEQ")  issued Mine
Permit No. 660 that is required for GMMV to develop the underground Jackpot Mine
and mine the uranium deposits.  The proposed mine has had no previous operators,
and will be a new mine when opened.  The Big Eagle Mine and related claim groups
(which are near the  proposed  Jackpot  Mine and are part of the Green  Mountain
Claims held by the GMMV),  are accessible by county and private  roads.  The Big
Eagle Mine was first operated by Pathfinder Mines  Corporation  ("PMC") starting
in the late 1970s.

         Sheep Mountain

         Unpatented  lode mining claims,  underground and open pit uranium mines
and mining  equipment  in the Crooks Gap area are  located on Sheep  Mountain in
Fremont County,  Wyoming and are adjacent to and west of the GMMV mining claims.
From 1988 to June 1, 1998,  these  assets were held by Sheep  Mountain  Partners
("SMP"). On June 1, 1998, USECC received back from SMP all of the Sheep Mountain
mineral properties and equipment,  in partial settlement of disputes with Nukem,
Inc. ("Nukem") and its subsidiary Cycle Resource Investment Corp. ("CRIC").  The
disposition of SMP cash and the CIS uranium supply contracts, remain in dispute.
See "Legal  Proceedings."  The Sheep  Mountain  Mines 1 and 2 are  accessible by
county and private  roads and were first  operated by Western  Nuclear,  Inc., a
subsidiary of Phelps Dodge Corporation, in the late 1970s.

         Yellow Stone Fuels Corp.

         Approximately 9,480 acres of properties are held by 282 unpatented lode
mining  claims  which have been staked by YSFC,  plus four state  leases held by
YSFC. The properties are located in Wyoming and New Mexico,  and are believed to
be prospective of uranium and suitable for in-situ leaching.

         The property interests of USE in Utah through Plateau Resources Limited
are:

         The  Tony M Mine  and  the  Frank  M  properties,  underground  uranium
deposits in San Juan County, Utah located partially on Utah State mining leases.
These properties are accessible by county roads.

         Plateau  is the lessee of the Tony M Mine and  portions  of the Frank M
properties and has posted a bond securing Plateau's obligations to reclaim these
properties.  The Tony M mine was  originally  developed  by  Plateau at the time
Plateau was owned by Consumers Power Company ("CPC"), a Michigan public utility.
Significant areas of uranium mineralization have been accessed and delineated by
the prior owner's underground  workings.  When the Tony M Mine was in production
(while Plateau was owned by CPC), it produced ore containing from three to eight
pounds of uranium  concentrates  per ton.  Some of this ore was processed at the
Shootaring Mill. In addition, low grade uranium ore was stockpiled at the Tony M
Mine and at the Shootaring Mill.

         Plateau also  acquired the Velvet Mine and the nearby Woods  Complex in
the Lisbon Valley area in southeastern Utah. The Velvet Mine was fully developed
and permitted by its prior owner and is located  approximately 178 miles by road
from the Shootaring Mill. The Woods Complex was formerly an operating

                                       21

uranium  mine with a remaining  undeveloped  resource.  Access to this  resource
would be by  extending  a drift  approximately  2,500 feet from the former  Wood
Mine.  The  Woods  Mine  property  is not  permitted,  but USE does  not  expect
difficulty in obtaining a new permit because the surface facilities would occupy
the site that has been disturbed from previous operations.

         Plateau Resources Limited is a wholly-owned subsidiary of USE, however,
Crested will have an interest in Plateau.  See "Plateau  Shootaring Canyon Mill"
below.

The Green Mountain Mining Venture ("GMMV") Project

         GMMV. In fiscal 1998, USE and USECC signed the Acquisition Agreement to
acquire  Kennecott  Uranium  Company's  interest in the GMMV. The following is a
description  of the formation of GMMV and certain of its terms,  which have been
modified as a result of the Acquisition Agreement and related  transactions,  as
set forth under the "Amendment to GMMV" below.

         In fiscal  1991,  USE and USECC  entered  into an  agreement to sell 50
percent of their  interests in the Green Mountain  uranium  claims,  and certain
other  rights,  to Kennecott  for  $15,000,000  (USE's share of the proceeds was
$12,600,000,  and the balance was  Crested's)  and a commitment  by Kennecott to
fund the first $50,000,000 of GMMV expenditures pursuant to Management Committee
budgets.  At the same time, USE and USECC ("USE  Parties") and Kennecott  formed
the GMMV and entered into a joint venture  agreement (the "GMMV Agreement") with
the USE Parties to develop,  mine and mill  uranium ore from the Green  Mountain
Claims, and market U3O8.

         After the first $50,000,000 of GMMV expenditures  advanced by Kennecott
is spent (which has been completed,  see "Properties and Mine Plan" below),  the
GMMV expenses are to be shared by the parties generally in accordance with their
participating  interests (50 percent  Kennecott,  50 percent USE  Parties).  The
agreement also provides that Kennecott will pay a disproportionate  share (up to
an additional  $45,000,000)  of GMMV  operating  expenses,  but only out of cash
operating  margins from sales of processed  uranium at more than  $24.00/lb (for
$30,000,000 of such operating expenses),  and from sales of processed uranium at
more than $27.00/lb (for the next $15,000,000 of such operating expenses).

         Pursuant to the GMMV Agreement,  each party's participation interest in
the GMMV is subject to reduction for voluntary or involuntary failure to pay its
share of  expenses  as  required  in  approved  budgets  (including  Kennecott's
commitment to fund the initial $50,000,000 of the GMMV expenditures), so that in
effect, the interest held by each party collateralizes its performance. However,
a defaulting  party would  remain  liable for third party  liabilities  incurred
during the GMMV operations, proportionate to its interest before reduction.

         The GMMV  cash  flows  will be  shared  between  Kennecott  and the USE
Parties according to their participation  interests.  However,  105 of the Green
Mountain Claims, which cover the Round Park (Jackpot) uranium deposit, currently
believed to be the most significant mineralized resource on Green Mountain, were
formerly owned solely by USE.  Pursuant to an agreement between USE and Crested,
cash flow from production of uranium out of these 105 Green Mountain Claims will
be  distributed  only  to USE  and  Kennecott,  and  GMMV  expenditures  on such
properties will be shared 50 percent by USE and 50 percent by Kennecott. Milling
costs will be paid by USE and Kennecott as operating costs.

         The USE Parties'  share of GMMV cash flow resulting from the balance of
the properties (outside the 105 claims),  which were previously owned by USE and
Crested together,  will be shared equally by USE and Crested.  GMMV expenditures
from such properties  will be shared 25 percent each by USE and Crested,  and 50
percent by Kennecott.  Such latter properties are expected to be developed after
the Round Park  (Jackpot)  deposit is placed  into  production  and the  uranium
deposits on these properties may be accessed through the

                                       22

<PAGE>



proposed  tunnels at the Jackpot Mine.  Development work at the Jackpot Mine was
temporarily halted in late July 1998, see "USEC Inc." below.

         The GMMV Management  Committee has three Kennecott  representatives and
two USECC  representatives,  acts by majority  vote, and appoints and supervises
the project manager.  In fiscal 1993,  Kennecott became the GMMV project manager
and has continued as project manager through the date of this Prospectus.  USECC
has continued work on a contract basis at Kennecott's request.

         Activities  on the GMMV  properties  have  included  environmental  and
mining  equipment   studies,   mine  permitting  and  planning  work,   property
maintenance,  setting up a uranium marketing program, acquisition and monitoring
of the  Sweetwater  Mill and  preparation of an application to the U. S. Nuclear
Regulatory  Commission  ("NRC") to convert  the  Sweetwater  Mill  license  from
standby  to  an  operating  license.  USE  has  completed  the  construction  of
additional  mining  support  facilities  at  the  Jackpot  Mine  including;  the
installation of natural gas lines and phone services; construction of a new shop
building  containing  offices,  a dry-change  room,  emergency  generators,  air
compressors  and  mechanical  repair  base;  upgrading  the ore haul  road;  and
installation  of a conveyor and stacker and other  incidental  mine  activities,
while  maintaining  all permits and licenses at the Jackpot Mine and  Sweetwater
Mill. For underground mine development  work, as of the date of this Prospectus,
the GMMV has driven twin decline  tunnels 18 feet wide and 12 feet high on a -17
percent grade  approximately 2,000 feet each into Green Mountain with 1,000 feet
of cross cuts between the  declines.  All of these  development  costs in fiscal
1998  and to  date  in  fiscal  1999  have  been  funded  through  approximately
$14,000,000 advanced to the GMMV in connection with Kennecott's $50,000,000 work
commitment (for its 50 percent interest).

Amendment to GMMV

         On June 23, 1997,  USE and USECC signed an  Acquisition  Agreement with
Kennecott,  for the  right  to  acquire  Kennecott's  interest  in the  GMMV for
$15,000,000  and  other  consideration.  This  Agreement  was not  closed by the
October  30,  1998  deadline  because  of  difficulties  in  trying to raise the
financing in light of current prices in the uranium oxide market. Kennecott paid
USE and USECC $4,000,000 as a purchase option, and committed to provide the GMMV
up to  $16,000,000  for  payment  of  reimbursable  costs  incurred  by USECC in
developing the proposed  underground  Jackpot Uranium Mine for production and in
changing the status of the Sweetwater Mill from standby to operational. See "USE
Management's Discussion and Analysis - Liquidity and Capital Resources - May 31,
1998."  The  work was  performed  by USECC  as  lessee  of all the GMMV  mineral
properties  under a Mineral  Lease  Agreement  between  the GMMV and USECC  (the
"Mineral  Lease"),  and as an independent  contractor under a Contract  Services
Agreement (the "Mill Contract")  between  Kennecott (as manager of the GMMV) and
USECC.  Both  the  Mineral  Lease  and the  Mill  Contract,  as well as a Fourth
Amendment to the GMMV Mining Venture  Agreement among  Kennecott,  USE and USECC
(the "Fourth  Amendment to the GMMV  Agreement"),  were executed  simultaneously
with  the  Acquisition  Agreement.  Under  the  Fourth  Amendment  to  the  GMMV
Agreement,   Kennecott  received  a  credit  against  its  original  $50,000,000
commitment to fund the GMMV. See "Properties and Mine Plan" below.

         The funding was advanced to Kennecott by an affiliate, Kennecott Energy
Company  ("KEC") under a secured  recourse  Promissory Note (the "Note") bearing
interest at 10.5% per annum starting in April 1999 until paid in full. As of the
date of this Prospectus,  approximately  $12,900,000 of the $16,000,000 has been
provided to the GMMV. The  Acquisition  Agreement was not closed,  and therefore
the Note  remains an  obligation  of Kennecott  alone.  The Note is secured by a
first mortgage lien against  Kennecott's  50% interest in the GMMV pursuant to a
Mortgage granted by Kennecott to KEC.

         Because the Acquisition Agreement was not closed, the Mineral Lease and
Mill Contract were  terminated,  and all  operations on the GMMV project are now
conducted pursuant to the amended GMMV

                                       23

<PAGE>



Agreement. USE and USECC, and Kennecott retain their respective 50% interests in
the GMMV,  and  Kennecott's  obligation to repay the money loaned by KEC remains
Kennecott's  obligation,  without any adverse  effect on the 50% interest in the
GMMV held by USE and USECC.  However,  the  Jackpot  Mine  development  work and
Sweetwater  Mill  upgrade  work  funded  by  $12,900,000  advanced  (out  of the
$16,000,000  loan) has benefitted  all parties.  The GMMV parties will remain in
the GMMV, and the development, mining and milling costs will be paid for by such
parties.  If one of the parties does not pay its share,  its  percentage  in the
GMMV is  reduced  if the other  party pays  instead.  Kennecott  may not wish to
participate  further in the project. If USE has the funding to pay for all costs
to continue  the  development  of the Jackpot  Mine and the upgrade  work at the
Sweetwater  Mill,  and USE makes the  decision to  continue  the  project,  then
Kennecott's  interest  would be reduced.  Thus,  it is  possible  that USE could
indirectly purchase Kennecott's interest through funding the project through the
GMMV.  USE does not presently  have the financial  resources to fund the GMMV by
itself.

         The USE Parties and Kennecott  have not agreed upon the GMMV budget for
the three month period ending February 28, 1999, and the USE Parties will not be
paying  for their  share of that  budget  of  expenditures.  Therefore,  the USE
Parties' 50% interest in the GMMV will be reduced by a small amount.
However, the GMMV will not be affected otherwise.

         Kennecott, which is one-half owner of the GMMV, has determined that its
investment in the GMMV is "fully impaired."  Kennecott has more than $52 million
invested in the GMMV  (including  the $15 million  paid to USE when the GMMV was
formed in 1991), compared to USE/Crested's investment of approximately $950,000.
Therefore,  even though Kennecott,  and USE/Crested,  are one-half owners in the
GMMV,  Kennecott  would have to realize  significantly  greater  cash flows than
USE/Crested out of GMMV  operations to recover its investment.  See GMMV Audited
Financial Statements included in this Prospectus.

         USE believes the decisions to finish the Jackpot Mine development work,
get the  Sweetwater  mill  licensed for  operation  and start mining  operations
should be based on careful  analysis  of all of the  project  mining and milling
costs,  and that pricing  models for long term contracts to supply uranium oxide
to utilities  should be taken into  account.  See "Uranium  Market  Information"
below.

         USE will continue to evaluate project mining and milling costs, and the
uranium oxide market in terms of both spot market  prices and  potential  demand
from utilities for long term supply contracts. It is possible that no impairment
of USE's  investments in its uranium  properties  (including the Utah properties
and the properties held by YSFC) will be necessary. However, it is also possible
that an impairment,  or reduction in the carrying value of the uranium  property
investments,  will be necessary in the future.  Any impairment would be recorded
as an expense on USE's consolidated statement of operations,  and a reduction in
total assets on its balance sheet.

         USEC Inc. In 1992,  Congress  enacted  the "Energy  Policy Act of 1992"
creating the U.S. Enrichment Corporation ("USEC") to operate the U.S. Department
of Energy's ("DOE") uranium enrichment program. Congress later enacted the "USEC
Privatization  Act of 1996" to  privatize  USEC and  allowed the DOE to transfer
various  forms of  uranium to USEC.  The DOE has  transferred  approximately  75
million  pounds of uranium and uranium  equivalents  to USEC.  On July 22, 1998,
USEC changed its name to USEC Inc. and became a publicly traded company. Because
of the anticipated negative impact of USEC Inc.'s sales of new uranium inventory
in the market (see "Marketing - U.S.  Enrichment  Corporation" below) on uranium
oxide  prices,  on July 31, 1998,  Kennecott and USE and Crested made a business
decision to temporarily place the Jackpot Mine on standby, which resulted in the
lay off of  approximately  47 employees.  Resumption of development  work by the
GMMV will depend on resolution of the USEC Inc.  uranium  inventory  sales issue
(see "U.S.  Enrichment  Corporation" below and "Legal Proceedings") and improved
uranium  prices,  and USE's  ability to raise the funds to pay its share of GMMV
costs.  USE believes the GMMV's decision to place the development of the Jackpot
Mine on standby, should be viewed as an interim event, because anticipated

                                       24

<PAGE>



improved  uranium  prices  based  on  supply  and  demand  projections,  or even
continued level prices,  could lead to a decision to resume  development work on
the Jackpot Mine. See "Uranium Market Information" below.

Properties and Mine Plan

         The GMMV owns a total of 521 claims on Green  Mountain,  including  the
105 claims on which the Round Park (Jackpot) uranium deposit is located. Surface
rights are owned by the United States Government under management by the BLM. In
addition,  other uranium  mineralization  has been delineated in the Phase 2 and
Whiskey  Peak  deposits  on these  claims,  which  formerly  belonged to USE and
Crested.  These  deposits are  undeveloped.  "Mineral  Deposit" or  "mineralized
material"  is a  mineralized  body which has been  delineated  by  appropriately
spaced drilling and/or underground  sampling to support a sufficient tonnage and
average grade of metal(s).  Such a deposit does not qualify as a reserve until a
comprehensive  evaluation  based upon unit cost,  grade,  recoveries,  and other
material  factors conclude legal and economic  feasibility.  Roads and utilities
have been put in place, which are satisfactory to support mine development.

         The GMMV also owns the Big Eagle  Properties on Green  Mountain,  which
contain substantial uranium  mineralization,  and are adjacent to the other GMMV
mining claims.  The Big Eagle Properties  contain two open-pit mines, as well as
related roads, utilities,  buildings,  structures,  equipment and a stockpile of
500,000 tons of uranium material with a grade of approximately one pound of U3O8
per ton of mineralized material. The assets include two buildings (38,000 square
feet and 8,000  square  feet)  formerly  used by  Pathfinder  Mines  Corporation
("PMC") in mining operations. Also included are three ore-hauling vehicles, each
having a 100-ton  capacity.  Permits  transferred to the GMMV for the properties
include:  a permit to mine, an air quality permit, and water discharge and water
quality permits.  The GMMV owns the mineral rights to the underlying  unpatented
lode mining claims.

         The Round Park  (Jackpot)  mining  claims  contain  deposits of uranium
which  have been  estimated  to  contain  52,000,000  pounds of U3O8;  the grade
averages 4.6 pounds of U3O8 per ton of mineralized  material.  The GMMV plans to
mine this  mineralized  material from two decline tunnels (-17 percent slope) in
the Jackpot  Mine,  which will be continued  underground  from the south side of
Green Mountain when operations resume. The first of several mineralized horizons
is about 2,300 feet vertically down from the top of Green Mountain.

         The  declines  will  ultimately  extend up to 12,300  feet in length to
access  the  different  zones  of the  deposit;  one  decline  will be used  for
ventilation and transportation of personnel, and the other will convey ore, rock
and waste out of the mine.  The mine plan  estimates  that the Jackpot Mine will
produce  about 3,000 tons of uranium ore per day and will have an expected  mine
life of 13 to 22 years. The Big Eagle Mine facilities  located about three miles
west of the Jackpot  Mine site will be  utilized.  As many as 250 workers may be
required during full mining operations. To the date of this Prospectus,  USE has
run approximately 2,000 feet of tunnel in each decline.

         The USE Parties  expect the  Jackpot  Mine  development  costs will not
exceed  an  additional  $10,000,000  to  reach  the  "B"  zone to  continue  the
development  in the ore at the Round Park deposit.  However,  cost estimates may
change as the development progresses.  Pursuant to the GMMV Agreement, Kennecott
agreed  to  fund  the  initial   $50,000,000  in  development   costs  including
reclamation  costs. To April 30, 1997, such expenditures  totaled  approximately
$20,355,142.  In fiscal 1998, approximately $10,160,896 of additional GMMV costs
had  been  funded  by  advances  to the  GMMV  out of the  $16,000,000  loan  to
Kennecott.  With the 2 for 1 credit provision in the Acquisition Agreement which
also applied to the $4,000,000 purchase option payment,  Kennecott had completed
its   $50,000,000   commitment.   Since  June  1997,   Kennecott   has  advanced
approximately  $14,000,000 of the $16,000,000 to the GMMV,  leaving a balance of
$2,000,000.  Whether this $2,000,000 will be made available by Kennecott for the
GMMV to keep the Jackpot Mine on standby  status has not been  determined  as of
the date of this Prospectus.

                                       25

         Sweetwater  Mill.  In fiscal 1993,  the GMMV  acquired  the  Sweetwater
uranium processing mill and associated  properties located in Sweetwater County,
Wyoming,  approximately  23 miles south of the  proposed  Jackpot  Mine,  from a
subsidiary  of  Union  Oil  Company  of  California  ("UNOCAL"),   primarily  in
consideration of Kennecott and the GMMV assuming environmental liabilities,  and
decommissioning and reclamation obligations.

         Kennecott is manager and operator of the Sweetwater  Mill and, as such,
will be compensated by the GMMV out of  production.  Payments for  pre-operating
management  will be based on a sliding scale  percentage of mill cash  operating
costs prior to mill operation;  payments for operating  management will be based
on 13 percent of mill cash  operating  costs when  processing  ore. Mill holding
costs  have been paid by the GMMV and  funded by  Kennecott  as part of its (now
completed) $50,000,000 funding commitment.

         The Sweetwater Mill includes buildings,  milling and related equipment,
real estate  improvements,  mining and mill site claims and other real  property
interests,  personal  property and  intangible  property  (including  government
permits  relating to  operation of those  properties).  The major assets are the
mill buildings and equipment located on approximately 92 acres.

         The mill was designed as a 3,000 ton per day ("tpd") facility. UNOCAL's
subsidiary,  Minerals  Exploration  Company,  reportedly  processed in excess of
4,200 tpd for sustained  periods.  The mill is one of the newest uranium milling
facilities in the United  States,  and has been  maintained  in good  condition.
UNOCAL has reported that the mill buildings and equipment have historical  costs
of $10,500,000 and $26,900,000, respectively.

         As  consideration  for the  Sweetwater  Mill,  GMMV agreed to indemnify
UNOCAL  against  certain  reclamation  and  environmental   liabilities,   which
indemnification  obligations are guaranteed by Kennecott Energy and Coal Company
(parent of Kennecott  Uranium  Company).  GMMV has agreed to be responsible  for
compliance with mill  decommissioning  and land reclamation  laws, for which the
environmental   and   reclamation   bonding   requirements   are   approximately
$24,330,000,  which includes a $4,560,000  bond required by the NRC. None of the
GMMV future  reclamation  and closure  costs are  reflected in the  Consolidated
Financial  Statements  (see  "Notes  F  and  K  to  USE  Consolidated  Financial
Statements").

         The  reclamation  and  environmental  liabilities  assumed  by the GMMV
consist of two  categories:  (1) cleanup of the inactive open pit mine site near
the mill (the source of ore feedstock for the mill when operating under UNOCAL),
including water (heavy metals and other contaminants) and tailings (heavy metals
dust and other contaminants  requiring abatement and erosion control) associated
with the pit;  and (2)  decontamination  and  cleanup  and  disposal of the mill
building,  equipment and tailings cells after mill decommissioning.  On June 18,
1996,  Kennecott  established  an  irrevocable  Letter of Credit  through Morgan
Guaranty Trust Company of New York City in the amount of $19,767,079 in favor of
the  Wyoming  Department  of  Environmental  Quality  ("WDEQ")  for  reclamation
requirements  of the GMMV.  The  Letter of Credit  was  increased  by $10,000 on
August 26, 1996 to cover  off-permit  wetland  enhancement.  The WDEQ  exercises
delegated  jurisdiction from the United States  Environmental  Protection Agency
("EPA") to  administer  the Clean Water Act and the Clean Air Act,  and directly
administers  Wyoming statutes on mined land reclamation.  The Sweetwater Mill is
also  regulated  by the NRC for  tailings  cells  and mill  decontamination  and
cleanup. The EPA has continuing jurisdiction under the Resource Conservation and
Recovery Act,  pertaining to any hazardous  materials  which may be on site when
cleanup work is started.

         Although  the GMMV is  liable  for all  reclamation  and  environmental
compliance  costs  associated  with mill and site  maintenance,  as well as mill
decontamination  and cleanup and site  reclamation and cleanup after the mill is
decommissioned,  USECC  believes it is unlikely USECC would have to pay for such
costs  directly.  First,  based on current  estimates of cleanup and reclamation
costs (reviewed annually by the oversight  agencies),  such costs covered by the
letters of credit or other surety appear to be within the $24,330,000 of

                                       26

<PAGE>



reclamation  bonds posted by Kennecott for GMMV. These costs are not expected to
increase  materially if the mill is not put into operation.  Second,  UNOCAL has
agreed that if the GMMV incurs expenditures for environmental  liabilities prior
to the earlier of  commercial  production  by GMMV or  February 1, 2001,  (which
liabilities are not due solely to the operations of GMMV), then UNOCAL will loan
the GMMV the first $8,000,000  (escalated  according to the Consumer Price Index
to current dollars,  from 1993) of such expenditures.  Any reimbursement for the
loan may only be  recovered by UNOCAL from 20% of future cash flows from sale of
uranium  concentrates  processed through the Sweetwater Mill. Third,  payment of
reclamation and environmental  liabilities  related to the Mill is guaranteed by
Kennecott. Last, the GMMV will set aside a portion of operating revenues to fund
reclamation and environmental liabilities when mining and milling operations are
finally shut down.

         Kennecott  will be  entitled  to  contribution  from the USE Parties in
proportion  to their  participating  interests  in the  GMMV,  if  Kennecott  is
required to pay mill cleanup  costs  directly  pursuant to its  guarantee.  Such
contributions  would be required only if the liabilities  cannot be satisfied by
Kennecott  within the balance of any  development  commitment as provided by the
Acquisition Agreement, after the credits provided by the Fourth Amendment to the
GMMV  Agreement  (see  "Amendment  to GMMV" above).  In addition,  if and to the
extent such liabilities  resulted from UNOCAL's mill operations,  and payment of
the  liabilities was required before February 1, 2001 and before mill production
resumes,  then up to  $8,000,000  (escalated)  of that  amount  would be paid by
UNOCAL,  before  Kennecott  would be required to pay on its guarantee.  However,
notwithstanding  the preceding,  the extent of any ultimate USECC  liability for
contribution to mill cleanup costs cannot be predicted.

         Permitting  and  Activities.  The  WDEQ  issued a mine  permit  for the
Jackpot  Mine on June 26,  1996.  This  Permit  allows the GMMV to proceed  with
construction of mine surface  facilities,  further  underground mine development
and eventual mining of the Round Park (Jackpot) Deposit.

         The  Jackpot  Mine  Plan  of  Operations   and  a  combination  of  the
alternatives  analyzed in the EIS will allow for the disposal of mine waste rock
in the Big Eagle  Mine pits some  three  miles from the  Jackpot  declines,  the
upgrading of existing roads,  and the  construction of new haul road segments to
transport  ore  to  the  Sweetwater   Mill.  These  roads  will  be  subject  to
modification  in  alignment  necessary to minimize or avoid  adverse  impacts to
riparian and cultural resources.

         Kennecott  has  initiated  discussions  and made  filings  with the NRC
regarding  amendments to the Source Material License to resume ore processing at
the Sweetwater  Mill. The NRC advised that the Operating  Permit would be issued
in October or November  1998,  however,  as of the date of this  Prospectus  the
Operating Permit has not been issued.

         USE believes all of the uranium operations in which it owns an interest
are in compliance  with these rules.  There  ultimately will be an effect on the
earnings of USE and Crested from  environmental  compliance  expenditures by the
GMMV,  since the GMMV operations are accounted for by the equity method.  GMMV's
expenses for compliance with  environmental  laws (as well as other matters) are
not expected to  materially  affect the cash flow of USE and Crested  during the
next two years.

Plateau's Shootaring Canyon Mill

         Acquisition of Plateau Resources Limited  ("Plateau").  In August 1993,
USE purchased from Consumers Power Company ("CPC"), all of the outstanding stock
of Plateau which owns the Shootaring Canyon uranium  processing mill and support
facilities  in  southeastern  Utah (the  "Shootaring  Mill") for a nominal  cash
consideration.  The Shootaring  Mill holds a source  materials  license from the
NRC. USE agreed:


                                       27

<PAGE>



         (a) to perform all studies, remedial or other response actions or other
activities  necessary from time to time for Plateau to comply with environmental
monitoring  and other  provisions  of (i) federal and state  environmental  laws
relating to hazardous or toxic  substances,  and (ii) the Uranium Mill  Tailings
Radiation Control Act, the Atomic Energy Act of 1954, and administrative  orders
and licenses  relating to nuclear or radioactive  substances or materials on the
property of, or produced or released by, Plateau; and

         (b) to  indemnify  CPC from all  liabilities  and costs  related to the
presence of hazardous  substances or radioactive  materials on Plateau property,
and to any future  violation  of laws and  administrative  orders  and  licenses
relating to the environment or to nuclear or radioactive substances.

         Plateau  transferred  $2,500,000  cash to fund  the "NRC  Surety  Trust
Agreement"  with a  commercial  bank as  trustee.  The  trustee is to pay future
decommissioning  costs of  Shootaring  Mill as directed  by the NRC.  The amount
transferred  to the  trust is the  minimum  amount  now  required  by the NRC as
financial assurance reclamation of the Shootaring Mill.

         Plateau transferred $4,800,000 cash to fund the "Agency Agreement" with
a  commercial  bank.  These funds will be  available  to  indemnify  CPC against
possible claims related to  environmental or nuclear matters as described above,
and against  third-party  claims related to an agreement between Plateau and the
third-party (see "Note K to the USE Consolidated Financial Statements for fiscal
year ended May 31, 1998").

         There are no present  claims  against funds held under either the Trust
Agreement or Agency Agreement.  Funds (including accrued interest) not disbursed
under  the  Trust  and  Agency  Agreements  will be paid  over to  Plateau  upon
termination of such Agreements with NRC concurrence.

         Subsequent  to  closing,  USE and Crested  agreed that after  Plateau's
unencumbered  cash has been depleted,  USE and Crested each will assume one-half
of Plateau's  obligations,  and share equally in Plateau's operating cash flows,
pursuant to the USECC Joint Venture.

         Shootaring  Mill and  Facilities.  The  Shootaring  Mill is  located in
southeastern  Utah and occupies 19 acres of a 265 acre plant site.  The mill was
designed to process 750 tpd,  but only  operated on a trial basis for two months
in  mid-summer  1982.  In 1984,  Plateau put the mill on standby  because of the
depressed U3O8 market.

         Plateau  also owns  approximately  90,000  tons of uranium  mineralized
material  stockpiled  at  the  mill  site  and  approximately  172,000  tons  of
mineralized  material  stockpiled at the Tony M Mine.  Included with mill assets
are tailings cells, laboratory facilities, equipment shop and inventory. The NRC
issued a license  to Plateau  authorizing  production  of uranium  concentrates,
however,  since the mill was shut down, only maintenance and required safety and
environmental  inspection  activities  were  performed and the source  materials
license with the NRC was for standby operations only. Plateau applied to the NRC
to convert the source  materials  license from standby to  operational  and upon
increasing the reclamation bond to $6,700,000, the NRC issued the new license on
May 2, 1997.  Plateau has an  additional  $1,600,000  of  government  securities
available for further bonding needs.

         In fiscal 1998, in anticipation of resuming milling operations, Plateau
has  significantly  performed a reactivation and  rehabilitation  program at the
Mill.  Plateau is awaiting approval of the ground water discharge permit for the
tailings facility from the State of Utah Water Control Division.

Ticaboo Townsite

         Plateau owns all of the outstanding  stock of Canyon  Homesteads,  Inc.
("Canyon"),  a Utah corporation,  which developed the Ticaboo, Utah townsite 3.5
miles  south  of the  Shootaring  Mill.  The  Ticaboo  site  includes  a  motel,
restaurant,  lounge,  convenience  store  and  single  family,  mobile  home and
recreational vehicle sites (all with utility access). The townsite is located on
a State of Utah lease near Lake  Powell and is being  operated  as a  commercial
enterprise.  An  amendment  was entered  into on April 1, 1997 on the Utah State
lease  covering the Ticaboo  townsite  whereby the State deeded  portions of the
Townsite to Canyon on a sliding scale basis.  USE and Crested are developing the
townsite and are selling home and mobile home sites.

Sheep Mountain Partners ("SMP")

         Partnership.  In February 1988, USE and Crested acquired uranium mines,
mining equipment and mineralized properties (Sheep Mountain Mines) at Crooks Gap
in  south-central  Fremont County,  Wyoming,  from Western  Nuclear,  Inc. These
Crooks  Gap  mining  properties  are  adjacent  to the  Green  Mountain  uranium
properties.  SMP mined and sold  uranium ore from one of the  underground  Sheep
Mines during  fiscal 1988 and 1989.  Production  ceased in fiscal 1989,  because
uranium  could be purchased  from the spot market at prices below the mining and
milling costs of SMP. In December 1988, USE and Crested sold 50 percent of their
interests in the Crooks Gap properties to Nukem's  subsidiary CRIC for cash. The
parties  thereafter  contributed  the  properties  to and formed Sheep  Mountain
Partners ("SMP"), in which USECC received an undivided 50 percent interest.  SMP
is a Colorado general partnership formed on December 21, 1988, between USECC and
Nukem, Inc. of Stamford, CT ("Nukem") through its wholly-owned  subsidiary Cycle
Resource  Investment  Corporation  ("CRIC").  Nukem is a uranium  brokerage  and
trading concern.  Each group provided one-half of $315,000 to purchase equipment
from Western Nuclear,  Inc.; USE and Crested also contributed their interests in
three uranium supply  contracts to SMP and agreed to be responsible for property
reclamation  obligations.  The SMP  Partnership  agreement  provided  that  each
partner  generally  had a 50  percent  interest  in  SMP  net  profits,  and  an
obligation to contribute 50 percent of funds needed for partnership  programs or
discharge of liabilities.  Capital needs were to have been met by loans,  credit
lines and contributions.

         SMP  was  directed  by  a  management  committee,  with  three  members
appointed by USECC, and three members appointed by Nukem/CRIC. The committee has
not met since 1991 as a result of the SMP arbitration/litigation.  During fiscal
1991,  certain  disputes  arose  between  the  partners of SMP.  These  disputes
resulted in  arbitration/litigation  and subsequent consensual  arbitration from
which an Order and Award was issued on April 18,  1996.  USE and  Crested  filed
petitions for  confirmation of the Order and Award with the U.S.  District Court
of Colorado and the Court has entered a Second Amended  Judgment  confirming the
monetary and  equitable  provisions  of the Order and Award.  Some of the claims
have been  resolved  by  settlement  between  the parties and the rest have been
determined by the 10th Circuit Court of Appeals ("CCA") (see "Legal  Proceedings
- - Sheep Mountain Partners Arbitration/Litigation").

         Properties.  Until June 1, 1998,  SMP owned 80  unpatented  lode mining
claims on the Crooks Gap properties, including two open-pit and five underground
uranium  mines and an  inventory of uranium  ore. In  connection  with a partial
settlement of  litigation/arbitration  between  USE/Crested and Nukem/CRIC,  SMP
conveyed these mineral  properties and equipment to USECC.  Production  from the
properties is subject to  sliding-scale  royalties  payable to Western  Nuclear,
Inc.,  with  rates  ranging  from  one to  four  percent  on  recovered  uranium
concentrates.  As of  October  30,  1998,  SMP  and/or  USE and  USECC  owned 98
unpatented  lode mining claims and a 644 acre Wyoming State Mineral Lease in the
Crooks Gap area.

         Various   structures  and  equipment  are  located  on  the  properties
including three operating and three  non-operating  mine headframes with hoists,
maintenance  shops,  offices,  and other buildings,  equipment and supplies.  An
ion-exchange plant is located on the properties.

                                       29

<PAGE>



         Of the claims,  which contain a previously-mined  open-pit uranium mine
and three underground mines,  Pathfinder Mines Corporation ("PMC") had the right
to mine a portion (the Congo area), by open-pit or in-situ techniques to certain
depths,  without royalty or other obligations to USECC. On October 30, 1998, PMC
transferred all its interest in the Congo area back to USECC.

         The ion exchange  plant on the  properties  was used to remove  natural
soluble uranium from mine water.  USE, on behalf of USECC,  has submitted a plan
to the NRC to decommission this facility and obtained a three year extension for
timeliness  of  decommissioning.   Management  is  reviewing  the  economics  of
relicensing  this facility as part of a potential  in-situ leach uranium  mining
operation.

         Property   Maintenance.   As  operating  manager  for  SMP,  USECC  was
responsible for exploration, mining, and care and maintenance of the SMP mineral
properties. USECC was to have been reimbursed by SMP for certain expenditures on
the properties.  During the SMP  arbitration/litigation,  Nukem/CRIC  refused to
allow SMP to pay USECC for care and  maintenance and other work performed on the
properties  since  the  spring of 1991.  As part of the Order and Award  made on
April 18, 1996, the Arbitration  Panel awarded USECC $2,065,989 for Nukem/CRIC's
50% share of care and maintenance  expenses for the SMP properties plus interest
of $446,834 to March 31, 1996 and per diem cost of $616  thereafter.  See "Legal
Proceedings   Sheep  Mountain  Partners   Arbitration/Litigation   -  Stipulated
Arbitration."  Currently,  USECC has a maintenance staff on site to care for and
maintain the mines and pump mine water to prevent  flooding of the mines,  which
could destroy  equipment and the concrete  lined vertical  shafts  accessing the
various levels of uranium mineralization.

         SMP  Marketing.  Nukem,  Inc.  was  engaged by SMP to provide  SMP with
financial  expertise  and  marketing  services.  SMP  entered  into a  marketing
agreement with CRIC,  which was  concurrently  assigned to and assumed by Nukem.
Nukem was to provide  marketing  and trading  services for SMP,  which  included
acquiring uranium for SMP by purchasing or borrowing. Nukem was to be reimbursed
at its direct costs for acquiring such uranium for SMP. USECC, SMP and Nukem had
seven long-term contracts plus an additional  long-term contract with a domestic
utility  that  was  awarded  to SMP by the  Arbitration  Panel  (three  of these
contracts  remained in SMP until the partial  settlement  on June 1, 1998).  The
contracts all were for sales of uranium originally to eight domestic  utilities.
SMP's   uranium   supply   contracts   were  either   base-price   escalated  or
market-related (referring to how price is determined for uranium to be delivered
at a future date).  Base- price  escalated  contracts set a floor price which is
escalated  over the term of the  contract  to  reflect  changes in the GNP price
deflator.  Two of the base priced  contracts  have been  fulfilled and the third
base-price  escalated  contract of SMP required a delivery of 130,000  pounds of
uranium  concentrates on May 15, 1997 which was made,  completing that contract.
The  fourth  contract  of  SMP  (which  has  been  transferred  to  USECC)  is a
market-related  contract,  and calls for delivery of  unspecified  quantities of
U3O8 totaling  approximately  1,000,000  lbs.  U3O8  (depending on the number of
reactors this utility is operating and their consumption levels).  This contract
may be completed in calendar 2000.

         Under the  market-related  contracts,  the purchaser's  cost depends on
quoted market prices based on estimated  prices at which a willing  seller would
sell its U3O8 during specified periods before delivery.

         Through fiscal 1997 and for prior years,  USECC and its affiliates have
satisfied most of these contracts with uranium concentrates  previously produced
by SMP,  borrowed from others,  or purchased on the open market. In fiscal 1998,
$858,000 in revenues was received  representing  USE's portion of revenues for a
delivery made (apparently in late fiscal 1997) by Nukem. See "Legal  Proceedings
- - Sheep Mountain Partners Arbitration/Litigation."

         Permits. Permits to operate existing mines on the Crooks Gap properties
have been  issued by the State of  Wyoming.  Amendments  are  needed to open new
mines within the permit area. As a condition to issuance of the permits, a NPDES
water discharge permit under the Clean Water Act has been obtained.

                                       30

<PAGE>



Monitoring  and  treatment  of water  removed from the mines and  discharged  in
nearby Crooks Creek is generally  required.  During the past two years,  SMP did
not  discharge  wastewater  into Crooks  Creek,  and the mine water is presently
being discharged into the McIntosh Pit.

Uranium Market Information.

         There are  currently  nine  producers of uranium in the United  States,
which  collectively  produced  5,800,000 pounds of U3O8 during calendar 1997 and
produced approximately 6,300,000 pounds in calendar 1996. Production in the U.S.
for 1998 is estimated at 5,000,000 pounds. In addition,  there are several major
producers  in Canada  (Cameco,  Cogema  Canada,  Ltd.,  Rio Algom and  Uranerz);
Australia  (Energy  Resources of Australia  and  Pancontinental  Mining,  Ltd.);
Africa (Cogema and Rio Tinto's  Rossing unit),  and Europe,  which  collectively
produced about 78,000,000  pounds of U3O8 during calendar year 1997 and produced
approximately  the  same  amount  in  calendar  1998.  Several  members  of  the
Commonwealth of Independent  States ("CIS") also export uranium into the western
markets  although the amount of such  exports to the United  States and European
markets are currently limited.

         Uranium is primarily used in nuclear reactors to heat water which drive
turbines to generate  electricity.  According to the Uranium  Institute based in
London,  England,  nuclear  plants  generated  approximately  17% of the world's
electricity  in 1996,  up from less than 2% in 1970.  According  to the  Uranium
Institute,  through the year 2000,  nuclear  generating  capacity is expected to
grow at 1 % per annum primarily as a result of new reactor  construction outside
the United States and increased efficiencies of existing reactors.

         In 1997,  440 nuclear  power  plants were  operating  and 28 were under
construction worldwide,  according to the Uranium Institute. Uranium consumption
by world commercial  reactors has increased from about 60,000,000 pounds in 1981
to approximately 165,000,000 pounds in 1997.

Supply and Demand

         From the early 1970s through 1980,  the Western World uranium  industry
was characterized by increasing  uranium  production fueled by overly optimistic
projections  of nuclear power  growth.  From 1970 to 1985,  production  exceeded
consumption by approximately 500,000,000 pounds U3O8. By the end of 1985, enough
inventory  had been amassed to fuel Western  World  reactor  needs for over five
years. In response, sales of excess inventory followed and prices plummeted from
highs above $40 per pound in 1979 to below $8 per pound U3O8 in 1992.  As prices
fell, Western World production declined  dramatically from a high of 115,000,000
pounds in 1980 to a low of 57,000,000 pounds by 1994. Since 1985, uranium demand
in the Western World has exceeded  Western World  production by over 400,000,000
pounds.  In 1995,  uranium demand in the Western World was  129,000,000  pounds,
nearly double the production of 66,000,000 pounds by Western World producers. In
1997, total world demand rose to an estimated  165,000,000  pounds,  while world
mine supply  increased  only to an estimated  93,000,000  pounds  (including the
78,000,000 pounds produced in North America,  Australia,  Africa and Europe, see
above).  Accordingly, by the end of 1997, excess inventory levels in the Western
World  (inventory  in excess of preferred  levels) had been reduced to less than
1.5 years of forward  reactor  requirements,  and the excess  inventories in the
U.S. had been reduced to less than one year of projected  forward  requirements.
This trend is expected to continue in calendar 1999.

         Countering the drawdown of Western World  inventories and  contributing
directly to the downturn of market  prices was the  importation  of uranium from
the CIS  republics,  and to a lesser  extent,  from Eastern  Europe and mainland
China starting in 1989. As the result of an anti-dumping  suit filed in the U.S.
("CIS  Anti-dumping  Suit") in 1991  against  republics  of the CIS,  suspension
agreements  were  signed  by six CIS  republics  (Russia,  Ukraine,  Kazakhstan,
Uzbekistan,  Kyrgyzstan  and  Tajikistan)  in  October  1992.  These  Suspension
Agreements  applied price related  volume quotas to CIS uranium  permitted to be
imported  into the U.S.,  so that to rectify  prior  damage to  domestic  United
States uranium producers from dumping sales of

                                       31

<PAGE>



U3O8,  all  spot  sales  of U3O8  delivered  into the  U.S.  now  reflect  quota
restrictions on U3O8 imports from the CIS.  Exceptions are allowed by provisions
which allow CIS  uranium to be imported  for  certain  long-term  uranium  sales
contracts  entered  into  with  domestic   utilities  prior  to  March  5,  1992
("grandfathered contracts").

         The Suspension Agreement with Russia was amended in March 1994 allowing
for up to 43,000,000 pounds of Russian uranium to be imported into the U.S. over
the 10 years  beginning  March  1994,  but only if it is  matched  with an equal
volume  of new U.S.  production.  Based on U.S.  consumption  for the  1994-2003
period (as  reported or  projected  by the  Department  of Energy),  the matched
volumes could account for up to 18% of the supply to the U.S. market during this
period.

         In  1995,  the  Republics  of  Kazakhstan   and  Uzbekistan   concluded
negotiations with the U.S. DOC to amend their respective Suspension  Agreements.
Both  amendments  lowered  initial prices  relating to their  respective  import
quotas  allowing  imports to occur.  Additionally,  the amendments  require that
uranium mined in those Republics and enriched in another country for importation
in the U.S. will count against their respective quotas. The Uzbekistan amendment
replaces the price-tied  quota system with one based upon U.S.  production rates
after October 1997. As U.S.  production rates increase,  additional imports from
Uzbekistan  are allowed.  Recently,  Kazakhstan  has  terminated  its Suspension
Agreement.

         Although  these  amendments to three of the  Suspension  Agreements may
increase the supply of uranium to the U.S. market,  they also provide  increased
predictability  concerning CIS imports into the U.S. Due to declining production
levels in the CIS  republics,  uranium  from these  sources  has  recently  been
difficult to obtain.  Consequently,  the market impact of CIS primary production
may be diminishing.

         In January  1994,  the U.S. and Russia  entered into an agreement  (the
"Russian HEU Agreement") to convert highly  enriched  uranium  ("HEU"),  derived
from dismantling  nuclear weapons,  to low enriched uranium ("LEU") suitable for
use in nuclear power plants. At a projected  maximum  conversion rate for HEU to
LEU,  approximately  24,000,000  pounds  of U3O8 per year will be  available  to
Western World markets.

         In 1996, the U.S.  Congress  passed  legislation in compliance with the
Suspension  Agreements,  which allows the  converted  Russian HEU material to be
sold in the U.S.  market at an annual  rate not to  exceed  2,000,000  pounds in
1998,  increasing  gradually to 20,000,000 pounds in 2009. At this maximum rate,
HEU material could supply  approximately 40% of annual U.S. reactor requirements
projected for 2009.  However,  the Russians may require much of the material for
its own internal use and the amounts which may be imported into the U.S.  cannot
be predicted.  In addition, an uncertain amount of HEU material is allowed to be
used in the U.S. for  overfeeding  of enrichment  facilities  and as a source of
Russian uranium for matching sales.

         Industry  analysts  expect annual  Western World  consumption  to be at
levels  between  135,000,000  and  165,000,000  pounds U3O8  through  2001.  USE
management  estimates that between 30,000,000 and 40,000,000 pounds U3O8 of this
demand could be filled by a  combination  of  government  stockpiles  (including
converted  Russian  and U.S.  HEU) and  imports  from CIS  republics  and former
Eastern  Bloc  countries.   To  achieve  market  equilibrium  by  2001,  primary
production  in the  Western  World will need to supply  between  95,000,000  and
120,000,000  pounds U3O8 on an annual basis subject to some  adjustment  for any
remaining inventory drawdown and limited uranium  reprocessing.  Production from
existing facilities in the Western World,  however, is projected to decline from
current levels  (78,000,000  pounds in 1998) to approximately  57,000,000 pounds
U3O8 by 2001 as reserves are depleted.  New production therefore will have to be
brought  on  line to fill a  potential  annual  gap of  between  38,000,000  and
63,000,000  pounds U3O8.  While current price levels may sustain 1998 production
levels,  USE believes  that higher prices will be needed to support the required
investment by other uranium  producers in new higher cost production  facilities
as lower cost production reserves are depleted.


                                       32

<PAGE>



         Overall,  USE believes  that  adequate  supply of U3O8 material to meet
firm demand (i.e. to supply future long term contracts with utilities) cannot be
sustained at spot price levels below  $15.00 per pound.  And,  while  production
remains at levels just above 50% of consumption  in the Western World,  existing
and planned new production  combined will not equal  consumption even if the new
production comes on stream as planned.

         Published  reports  indicate  that  approximately  31  percent  of  the
worldwide  nuclear-powered  electrical  generating  capacity is in the U.S.,  49
percent is in Western  Europe,  and 14 percent is in the Far East.  Although the
reactors in Western Europe have a greater aggregate generating capacity and fuel
usage,  the supply of uranium for those reactors has been secured for relatively
long periods.  The market  requiring the greatest supply of uranium for the next
few years is believed to be the United  States.  The Asia Pacific region is also
developing into a significant uranium consumer, due to announced plans for rapid
expansion  of nuclear  power  programs in Japan,  Korea,  Taiwan and the Russian
Federation.  This  region  accounts  for most of the 98 power  plants  which are
ordered or under construction.

         USEC INC. The United States Enrichment Corporation ("USEC") was created
by the United  States  Congress as part of the Energy  Policy Act of 1992.  USEC
began  operations  in July  1993 when the  United  States  Department  of Energy
("DOE")  transferred  the DOE's  uranium  enrichment  facilities  to USEC.  USEC
enriches uranium at two gaseous diffusion  process plants (at Paducah,  Kentucky
and near Portsmouth,  Ohio) as part of the process to transform  natural uranium
into fuel for commercial power plants. USEC has a substantial share of the world
market for  enrichment  services,  and dominates the North  American  market for
enrichment  services.  In 1996,  Congress enacted the "USEC Privatization Act of
1996" to  privatize  USEC and  allowed the DOE to  transfer  certain  amounts of
various forms of uranium to USEC.

         In July 1998,  USEC became a wholly-owned  subsidiary of USEC Inc. when
it completed its  privatization  through a $1.4 billion public  offering by USEC
Inc.  USEC  Inc.  represented  in  filings  with  the  Securities  and  Exchange
Commission  that it now holds or  intends to  acquire  95 metric  tons  enriched
uranium  (50 tons  highly  enriched,  45 tons low  enriched)  and 10,800 tons of
natural  uranium  (uranium  oxide as produced  from  uranium  milling,  prior to
concentration).  USEC Inc. has represented  its intention to supplement  uranium
enrichment services revenues through sales of natural uranium.

         Based upon the amounts of uranium USEC Inc. purportedly has, or will be
acquiring  in  shipments  from DOE,  USEC Inc.  may be  seeking to sell up to 75
million  pounds of uranium or uranium  equivalents  through the year 2005. On an
annual basis,  such sales would adversely impact the domestic uranium market for
producers  such as USE and  Crested,  because  USEC Inc.'s sales would amount to
more on an annual basis than all domestic producers  (including USE and Crested)
will produce and plan to sell combined.

         USE and Crested  believe that a substantial  portion of the uranium (45
metric tons of low  enriched  uranium and 7,000 tons of natural  uranium)  which
USEC Inc. has  acquired  and will acquire from the DOE, in fact was  transferred
and will be  transferred  by DOE in violation of the USEC  Privatization  Act of
1996.  USE and Crested have joined with other uranium  producers and the Uranium
Producers of America ("UPA") in the filing of a lawsuit for declaratory judgment
and  injunctive  relief  against the  Department of Energy,  with respect to the
excess  transfers,  in an attempt to prevent  USEC Inc.  from  enjoying a market
advantage over the domestic  uranium  producers  which is prohibited by law. See
"Legal Proceedings" below.

         Market  Summary -  Implications  for Future  Uranium  Prices.  With the
privatization  of USEC and the prospect of natural  uranium coming to the market
from USEC Inc.  inventories,  uranium prices may not rise significantly over the
next 12 months,  as  previously  had been  anticipated  in  reports by  industry
analysts and by USE management.  Nevertheless,  USE believes that uranium prices
eventually will be determined and moved up  significantly by the fundamentals of
the market, because all excess inventories built up in the 1980s will eventually
be  consumed.  In addition,  USEC Inc. has stated that USEC Inc.  would sell its
uranium in a

                                       33

<PAGE>



rational and  responsible  manner  indicating (in the opinion of USE management)
that USEC Inc.  may keep its market  sales at levels  which would not drive down
uranium prices.

         As detailed  below,  many projects have been delayed or postponed since
mid-1997 for various  reasons,  which will have a  significant  impact on future
supply/demand  fundamentals.  If, as it  appears  to be the case,  the  possible
introduction of the new USEC Inc. inventories  currently has a depressing effect
on the price of uranium  concentrates,  then new planned uranium production will
be curtailed more than indicated below.

</TABLE>



         With  these  delays,  postponements,  and  possible  further  delays or
cancellations of planned uranium  production  projects,  USE believes that it is
possible that the market price for uranium may increase  substantially  in mid -
to late  1999,  in  spite  of  possible  sales  from  the  USEC  inventory.  The
fundamentals for higher uranium prices are ascertainable. Currently, all nuclear
reactors worldwide consume approximately 160 million lbs. of natural uranium per
year and by most estimates, will continue at that rate for at least the

                                       34

<PAGE>



next 20 years. Total world production for 1997 was approximately 90 million lbs.
Over the next four years,  three mines  located in Canada (Key Lake,  Cluff Lake
and Rabbit Lake) will have exhausted their reserves and will be shut down. Three
new Canadian mines (McArthur  River,  McClean  Lake/Midwest  and Cigar Lake) are
scheduled to produce  approximately  40 million lbs. of U3O8  annually when they
are in full production.

         USE management believes that other delays and cancellations of projects
may be imminent and that eventually all inventories (government and public) will
be consumed.  New  significant  production  will be needed to fuel  existing and
planned reactors into the 21st century. USE management believes that prices must
rise  significantly  from current levels of  $10.00/lb.,  and possibly up to the
$18.00/lb.  range over the next 2-3 years, to motivate existing and new mines to
move forward as planned.  In addition,  no new mine/mill  construction  would be
justifiable  for  selling  into only the spot  market.  At least 80 percent of a
uranium  producer's  production has to be sold to long term  contracts,  because
only with long term  contracts  can the mine/ mill  process over the life of the
mine be planned and financed.

         In  contrast  to  finding,  developing  and mining new  properties  and
building  new mills,  USE's  uranium  properties  are  believed to contain  well
defined  uranium  deposits  delineated  by others  which do not require  further
exploration   work  prior  to   beginning   production.   Development   work  is
significantly advanced at both the principal Wyoming site (the Jackpot Mine) and
the Utah mines.  The uranium mills in Wyoming and Utah were acquired fully built
at no cost to USE and Crested,  and the remaining work required to put the mills
into operating status will not consume significant amounts of capital. For these
reasons,  USE  believes  that its uranium  properties  will be low cost  uranium
producers compared to some of the other uranium mines now in operation, and also
compared to the costs to develop new properties and build new uranium mills.

         Nonetheless  the decision by USE to put any mine into  production,  and
the  commitment of funds  necessary to implement that  commitment,  must be made
well in advance of the time when revenues from the mined  resource are received.
Price fluctuations  between the time the production  commitment is made, and the
time when production and sales occur, can significantly  impact the economics of
the mine. If the sales  revenues fall below  production  costs for a substantial
period of time,  it is  possible  that USE could  determine  that it is not then
economically feasible to continue production operations. Taking into account all
of the relevant factors  discussed above, USE intends  throughout fiscal 1999 to
seek the financing to put the uranium  properties  into  production,  and in the
meantime to seek long term  utility  contracts  to take the uranium  production,
with the  ultimate  goal of being in  production  in Wyoming in April 2000,  and
milling  the  stockpiled  uranium  in Utah in  early  fiscal  2000.  There is no
assurance such financing will be obtained,  nor is there  assurance  prices will
not  decrease,  which would make  obtaining  such  financing  more  expensive or
impossible.

         NUEXCO  Exchange  Value.  The market related  contracts to sell uranium
oxide to utilities  usually are based on an average of the Nuexco Exchange Value
("NEV") or some other market  quotes for 2, 3 or more months  before the uranium
delivery.  The high and low NEV  reported on U3O8 sales  during USE's past seven
fiscal years are shown below.  NUEXCO Exchange Values are now reported weekly by
TradeTech and  represents  its judgment of the price at which spot and near term
transactions for significant quantities could be concluded. NEVs for fiscal 1993
are higher for U.S.  transactions,  due to the impact of CIS import restrictions
since late 1992.  These prices ("US NEV") were reported by NUEXCO for spot sales
in the restricted U.S. market.

         NUEXCO's  restricted  market values ("U.S.  NEV") apply to all products
and  services  delivered  in the U.S.  as well as non-CIS  origin  products  and
services delivered outside the U.S.

         The foregoing  prices  represent  the "spot" market only,  and indicate
transactions  primarily  by  utilities  purchasing  to  cover  short  positions.
Long-term  supply  contracts,  which cover up to 90 percent of the uranium  sold
from year to year,  carry prices  which are in excess of the spot  market.  This
price premium is paid by the utilities to assure long term price stability;  the
producer  demands the premium to  compensate  for future price  increases  which
could (but may not) exceed the premium.  Utilities keep their long term contract
provisions confidential,  so it is difficult to assess any one utility company's
long term  contract  plans or needs.  The amount of the price  premium will vary
from time to time.

Gold

Sutter Gold Mine (California)

         Sutter Gold Mining Company. In fiscal 1991, USE acquired an interest in
the Lincoln Project  (including the underground  Lincoln Mine and the 2,800 foot
Stringbean  Alley decline) in the Mother Lode Mining  District of Amador County,
California.  The  entire  Lincoln  Project  is now owned by Sutter  Gold  Mining
Company, a Wyoming corporation ("SGMC"),  which is a 59% subsidiary of USE as of
November  30,  1998.  The Lincoln  Project has been renamed the Sutter Gold Mine
("SGM").

         In fiscal 1997,  SGMC completed  private  financings  totaling a net of
US$7,115,400  ($1,272,000  through a private  placement  conducted in the United
States by RAF Financial Corp., now American Fronteer  Financial Corp. or "AFFC",
and $5,843,400 through a private placement conducted in Toronto, Ontario, Canada
by C.M.  Oliver & Company  Limited).  The net proceeds of $6,511,200  from these
financings (after deduction of commissions and offering costs) are being applied
to pre-production mine development, mill design, permitting and property holding
and acquisition cost.  Additional  financing of up to $15,000,000 will be sought
to fund the development and  construction  of the mine/mill.  SGMC's  properties
contain  an  estimated  amount of  proven  reserves  (see  below).  Because  the
properties are not yet in production and the needed funding is not yet available
to do so  (gold  is at $290 per  ounce,  which  has  hampered  efforts  to raise
capital), the recorded value of SGMC's mineral properties has been reduced as of
May 31,  1998.  See "USE  Management's  Discussion  and  Analysis  of  Financial
Condition and Results of  Operations." If such financing is not available by the
end of fiscal 1999, or if gold prices do not improve, USE will determine whether
a  further  impairment  of the  carrying  value  of its  investment  in  SGMC is
necessary.  SGMC intends to fund the development and construction of the project
through private or public debt and/or equity  financing.  As of the date of this
Prospectus,  SGMC is in discussions with certain investment banks,  however,  no
agreements  for  financing  have been  reached,  and there is no  assurance  any
agreements will be reached.

                                       36

<PAGE>



         Due to the depressed gold price and gold equity  market,  SGMC deferred
the  start of  construction  of the 1,000  ton-per-day  gold  mill  complex  and
development of the underground mine.

         During  fiscal  1998,  amended  its 1993  Conditional  USE Permit  (see
"Permits and Future  Plans"),  finalized  the process flow of the mill,  entered
into the final design engineering contract with the engineering firm of Lockwood
Greene of Dallas,  Texas and started to build the entrance  road to the mine. In
fiscal  1999,  preparation  of the mill and  office  site  has  started  and the
engineering  firm has  finished  construction  drawings  for the  mill.  If SGMC
obtains the necessary  funding within the balance of fiscal 1999,  SGMC could be
in production in fiscal 2001. However, delays in obtaining financing would delay
the start of production.  Once a decision to commence  production is made,  from
that date, it is estimated it will take  approximately 18 months to complete the
mill complex construction and pour the first bar of gold.

         SGMC  does not have any  class of its  securities  registered  with the
Commission,  and none of its  securities  are  traded  in the  United  States or
Canada.

         After completion of the two private financings, and taking into account
a  restructuring  of the  ownership of USE and Crested in SGMC,  USE and Crested
each own the following securities of SGMC:

         (a) Together,  a majority (after the April 1998 transaction,  discussed
below) of the outstanding shares of SGMC Common Stock, which would be reduced in
the event  outstanding  warrants  held by the  remaining  Canadian  investors to
purchase 564,900 more shares of Common Stock are exercised at Cdn$6.00 per share
18  months  from  the date of  closing  of the  private  offerings  (which  were
completed  in May  1997) and the  outstanding  warrants  held by C.M.  Oliver to
purchase  145,480  more shares of Common  Stock are  exercised  at Cdn$5.50  per
share, before May 13, 1999.

         (b) Together,  a $10,000,000  Contingent  Stock  Purchase  Warrant (the
"USECC  Warrant")  which was issued to USE and  Crested in  connection  with the
restructuring of SGMC for the Canadian private  placement.  The USECC Warrant is
owned 88.9% by USE and 11.1% by Crested.  The USECC  Warrant  provides  that for
each ounce of gold over 300,000 ounces added to the proven and probable category
of SGMC's  reserves  (up to a maximum of  400,000  additional  ounces),  using a
cut-off  grade of 0.10 ounces of gold per ton (at a minimum vein  thickness of 4
feet),  USE and Crested will be entitled to cash or additional  shares of Common
Stock from SGMC (without paying  additional  consideration)  at SGMC's election.
The number of  additional  shares  issuable for each new ounce of gold  reserves
will be  determined  by dividing  US$25 by the greater of $5.00 or the  weighted
average  closing  price of the  Common  Stock  for the 20  trading  days  before
exercise of the USECC Warrant.  The USECC Warrant is exercisable  semi-annually.
SGMC may  prevent the  exercise  of the USECC  Warrant by paying USE and Crested
US$25 in cash for each new ounce of gold (payable out of a maximum of 60% of net
cash-flow from SGMC's mining operations).

         April 1998 Transaction for Cash and SGMC Special Warrants.  As of April
7, 1998,  USE entered into four separate  Stock  Purchase  Agreements  with four
Canadian investment funds, for the issuance of 658,895 shares of Common Stock of
USE, in consideration of the funds' payment to USE of $1,190,000 in cash and the
delivery to USE of 888,900  Special  Warrants of SGMC. The funds had paid SGMC a
total of Cdn$4,888,950 in May 1997, pursuant to a private offering in Canada, to
purchase  the Special  Warrants  from SGMC.  Each Special  Warrant  entitles the
holder to acquire from SGMC,  at no further  cost,  one share of Common Stock of
SGMC, and one Purchase  Warrant;  each Purchase  Warrant  entitles the holder to
purchase  one share of Common  Stock of SGMC,  at a price of Cdn$6.00  per whole
share (the "Purchase Warrants"), through November 13, 1998.

         Pursuant to the terms and conditions of the Special  Warrants,  if SGMC
were to fail to obtain  prospectus  qualification  before the  October  10, 1997
qualification deadline (as such terms were defined in the Special Warrants) from
the securities commissions of the Canadian Provinces wherein purchasers of the

                                       37
 
<PAGE>



Special Warrants  reside,  the holders of the Special Warrants would be entitled
to receive a dilution  penalty in the amount of 1.1 shares of SGMC Common  Stock
and 1.1  Purchase  Warrants,  for  each  Special  Warrant  exercised  after  the
qualification  deadline if  prospectus  qualification  were not  obtained by the
qualification  deadline.  Such qualification required listing of the SGMC shares
and Purchase Warrants on a principal Canadian stock exchange.

         The prospectus qualification was not obtained by SGMC, due primarily to
the drop in gold  prices in the latter  part of 1997 and the  resulting  lack of
interest in new listings of gold companies in the Canadian markets.  However, as
discussed below, none of the four Canadian Funds, has received additional shares
of SGMC Common Stock or additional  Purchase Warrants in payment of the dilution
penalty with respect to the Special Warrants and their  constituent  securities.
The  dilution  penalty  may have to be paid with  respect to the other  Canadian
investors in the Special Warrants.

         Each of the four  Canadian  Funds,  in order to diversify  and increase
their original investment, made offers to USE to purchase shares of USE $.01 par
value Common Stock.  Each of the four funds,  and USE,  negotiated  the terms of
acceptance  of the funds' offer by USE. As a result of the offer and  subsequent
negotiations  with each of the funds,  USE entered into separate  Stock Purchase
Agreements with the funds.

         USE received  consideration for its issued shares consisting of (i) net
cash proceeds,  from all four funds, of US$1,102,464 (after deduction of $87,536
in legal  fees and a fee  paid to a  Canadian  investment  banking  firm);  (ii)
888,900  Special   Warrants  of  SGMC  from  the  four  funds;   and  (iii)  the
relinquishment  by each of the  four  funds  of  their  rights  to the  dilution
penalty. USE issued 658,895 shares of Common Stock in consideration of the cash,
the Special Warrants,  and the  relinquishments.  The USE shares were restricted
securities,  but pursuant to the terms of the Stock Purchase Agreements, USE has
filed an effective  registration  statement  with the  Commission  to permit the
resale to the public of the funds' shares.

         The Stock Purchase  Agreements for three Canadian Funds,  and the Stock
Purchase Agreement for the fourth fund with respect to the cash portion thereof,
closed as of April 7, 1998,  at which date the  closing  bid price of USE shares
was $6.876. A price of $7.00 per USE share was utilized by the funds and USE for
purposes of  determining  the number of USE shares to be issued  under the Stock
Purchase Agreements.

         The dilution  penalty,  if paid, would have resulted in the issuance to
the Canadian  Funds of an  additional  88,890 shares of Common Stock of SGMC and
Purchase Warrants to buy another 88,890 shares of Common Stock of SGMC. USE will
retain the SGMC Special Warrants acquired from the Canadian Funds.

         In February  1999,  USE issued 89,158  restricted  shares of USE Common
Stock to acquire 207,500 shares of SGMC Common Stock. The SGMC shares which were
acquired  were part of the private  offering  through AFFC in fiscal  1997.  The
transaction  was based on a USE share value of $7.00 (2.33 SGMC shares for 1 USE
share),  and was initiated by USE to provide liquidity to the private investors.
As a  result  of the  transaction  (which  is now  completed),  USE's  ownership
interest in SGMC was slightly increased.

         USECC  Management  Agreement with SGMC.  Effective  June 1, 1996,  SGMC
entered into a Management  Agreement  under which USECC provides  administrative
staff and services to SGMC. USECC is reimbursed for actual costs incurred,  plus
an extra 10%  during  the  exploration  and  development  phases;  2% during the
construction  phase;  and 2.5%  during the mining  phase (such 2.5% charge to be
replaced  with a fixed sum which the parties  will  negotiate  at the end of two
years starting when the mining phase begins).  The Management Agreement replaces
a prior agreement by which USECC provided administrative services to SGMC.

         Properties.  SGMC  (through its  subsidiary  USECC Gold  L.L.C.)  holds
approximately  14 acres of  surface  and  mineral  rights  (owned),  55 acres of
surface  rights  (owned),  436 acres of surface  rights  (leased),  158 acres of
mineral  rights  (leased),  and 380  acres of  mineral  rights  (owned),  all on
patented mining claims near Sutter Creek, Amador County, California. The acreage
of mineral  rights owned will be decreased to about 280-300  acres in 1999.  The
properties are located in the western  Sierra Nevada  Mountains at from 1,000 to
1,500  feet  in  elevation;  year  round  climate  is  temperate.  Access  is by
California State Highway 16 from Sacramento to California State Highway 49, then
by paved county road approximately .4 miles outside of Sutter Creek.

         On October 1, 1996,  SGMC  entered into three  letter  agreements  (the
"Lincoln  Letter  Agreements")  with the property owners of 185 acres ("185 Acre
Property") on the west side of California  State Highway 49 ("Hwy 49") and 32.58
acres ("32 Acre  Property")  of minerals  which include 20.5 acres of surface on
the  east  side of Hwy 49  adjacent  to the  Stringbean  Decline.  The 185  Acre
Property is the  proposed new location for the Surface Fill Unit and the 32 Acre
Property provides the land necessary for access and utility easements to Hwy 49.

         Surface and mineral rights  holding costs will aggregate  approximately
$225,000 from June 1, 1998 through May 31, 1999.  Property taxes for fiscal 1999
are estimated to be $30,000.

         The leases are for varying  terms,  and require  rental  fees,  advance
production royalties,  real property taxes and insurance.  The lease that was to
expire in February 1998 has been extended  through its force majeure  clause due
to the low price of gold. Leases expiring before 2010 will generally be extended
automatically,  so long as minerals are continuously  produced from the property
that is subject to the lease or minimum  payments are made . Other leases may be
extended for various periods on terms similar to those contained in the original
leases.  Production  royalties  are from 2.5% to 6% (most are 4%).  The  various
leases have  different  methods of  calculating  royalty  payments  (net smelter
return and gross proceeds).

         A separate  holder of four of the  properties  that were assembled into
the  SGM  holds a 5  percent  net  profits  interest  on  production  from  such
properties, which was granted by a prior owner of the project. An additional 0.5
percent net smelter  return royalty is held by a consultant to a lessee prior to
that owner's  acquisition of the properties,  which 0.5 percent  interest covers
the same four properties.

         Through May 31, 1998, an estimated  $21,000,000 was spent on the SGM by
Meridian,  USECC Gold and other of their predecessors to acquire the SGM and for
mine  development,   mining  and  processing  bulk  samples  of  mineralization,
exploration,  feasibility studies,  permitting costs, holding costs, and related
general and  administrative  costs. The amount of such  expenditures  during the
1998 fiscal year was approximately $1,410,800 ($572,700 in 1997).

         Geology and Reserves.  The minerals  consulting  firm Pincock,  Allen &
Holt of  Lakewood,  CO ("PAH")  prepared a  prefeasibility  study of the Lincoln
Project  in fiscal  1994 (and  updated  the study in 1997).  PAH  reviewed  core
drilling  data on the Lincoln Zone on 100-foot  centers  from the  surface,  and
drilling on the Comet Zone from both surface and underground.  PAH also reviewed
data from drilling on the Keystone Zone from surface on 200-foot centers.  Total
data is from 162 exploration  core holes (surface and  underground),  with total
footage of 64,700 feet. PAH based its estimate of proven reserves on mineralized
material within 25 feet of sample  information;  probable reserves were based on
material located between 25 and 50 feet of sample information.

         Using a cutoff  grade of 0.15  ounces  of gold  per ton in  place,  PAH
estimates  the SGM  contains  approximately  350,000 tons of proven and probable
reserves  grading  approximately  0.4  ounces  of gold  per  ton.  If  operating
economics indicate a lower cutoff grade is feasible, the tonnages for the stated
reserves would be increased.  Historical data  (underground  maps and production
records) from historic (now closed)

                                       39

<PAGE>



mines within the SGM boundaries  indicate  certain areas of those mines were not
"mined  out,"  such  that  additional  mineralized  resources  may  exist on the
property.

         The  geology  within  the SGM is typical of the  historic  Mother  Lode
region  of  California,   with  a  steeply  dipping  to  vertical   sequence  of
metavolcanic and metasedimentary rocks hosting the gold-bearing veins. Depending
on location along the strike length on the vein systems,  the gold-bearing veins
are  slate,  metavolcanic  greenstone,  or an  interbedded  unit of  slates  and
volcanics.  The Lincoln  Project  covers over 11,000 feet of strike length along
the Mother Lode vein systems.

         Permits and Future  Plans.  In August 1993,  the Amador County Board of
Supervisors  issued a Conditional USE Permit ("CUP")  allowing mining of the SGM
and  milling  of  production,  subject  to  conditions  relating  to  land  USE,
environmental and public safety issues,  road construction and improvement,  and
site  reclamation.  The  permit  will  allow  construction  of the mine and mill
facilities  in stages as the project gets  underway,  thereby  reducing  initial
capital   outlays.   Additional   permits  (for  road  work,  dust  control  and
construction of mill and other surface  improvements)  need to be applied for in
due course. In August and September 1998, the Amador County Board of Supervisors
certified  the  Final  Subsequent  Environmental  Impact  Report  ("FSEIR")  and
approved all of the  amendments  requested by SGMC.  Amendments  to the CUP will
remove  two  tailings  dams,  eliminate  the need to USE  cyanide  on-site,  and
eliminate  mine  related  traffic on two county  roads.  The  certification  and
decision has been challenged in a lawsuit filed by a local citizens'  group, see
"Legal  Proceedings."Since SGMC already has a valid CUP, SGMC believes it may be
able to move forward on certain parts of the  development of the  mine/mill.  In
any event,  SGMC does not expect the  appeal  process to  materially  impact the
development plan or schedule.

         Proposed Mine Plan. In should be noted that the mine workings  actually
developed  may  vary  substantially  from  the plan  adopted,  depending  on the
different  conditions and grades of  mineralization  that are encountered.  SGMC
proposes to mine the Lincoln and Comet  Zones  initially  by access  through the
existing Stringbean Alley decline.  Production will be by overhand  cut-and-fill
and open sub-level stoping techniques.  Screened tailings from the mill (support
fill) will be used to back fill the stopes, which will stabilize the hanging and
foot wall vein rocks,  and greatly reduce the volume of processed ore going into
the Surface Fill Unit.

         Mining  at  startup  is  expected  to  increase  up to 500 tons per day
("tpd") during the first six months of mining  operations.  Ore will be conveyed
to the surface through an off shoot portal from the Stringbean Alley decline.  A
new  underground  level is  planned  to be driven at 1,000 feet above sea level,
(approximately  120 feet below surface) during the next six months.  Mining will
coincide with development of additional stopes and may allow an increase in mine
production  up to 1,000  tpd in  approximately  the  fourth  year of  operation.
Concurrently  with  production  mining,  SGMC intends to maintain an  aggressive
underground development program to delineate (on an on-going basis) two to three
years of developed ore in sight.

         Mill Plan.  There are three stages of milling and  processing  the ore.
The first stage  involves  wet grinding of the ore to the size of fine sand in a
semi-autogenous  grinding  ("SAG")  mill.  The resulting  finely-  milled ore is
treated in a gravity  separator which employs  centrifugal force to separate the
heavier free gold  particles  from the lighter rock  particles.  Next,  the gold
concentrate  is  run  across  a set of  cleaning  tables  to  upgrade  the  gold
concentrate.  The second stage takes the  middlings and tails from the first and
again involves wet grinding in a ball mill to a finer size particle. This ground
ore is again  treated  in a similar  gravity  separator  which is tuned for this
finer size  particle and the gold  concentrate  is run across a different set of
cleaning  tables.  The third stage  separates  the  remaining  gold by flotation
wherein  minute  quantities  of non-toxic  chemicals are added to the ground ore
which makes the gold bearing  particles attach to air bubbles.  The gold bearing
particles are then separated  from the ground ore into a flotation  concentrate.
At this stage, the flotation concentrate is either reground and processed with a
dilute  solution  of sodium  cyanide or shipped  offsite.  SGMC is  planning  on
shipping  the  flotation   concentrate  offsite,  even  though  its  CUP  allows
processing with

                                       40

<PAGE>



sodium cyanide. The mill is designed to produce several gold-bearing products: a
high-grade gravity concentrate; a flotation concentrate or a gold precipitate if
the cyanide process is used. These gold-bearing products will be smelted to dore
bullion for shipment to a precious metal refinery.  During processing, 95 to 97%
of the processed ore will be removed.  Of this material,  approximately 65% will
be placed underground as structural fill and 35% will be placed into the Surface
Fill Unit.

Molybdenum

         As holders of royalty,  reversionary  and certain  other  interests  in
properties located at Mt. Emmons near Crested Butte,  Colorado,  USE and Crested
are entitled to receive annual advance royalties of 50,000 pounds of molybdenum,
or cash equivalent  (one-half to each).  AMAX Inc. (which was acquired by Cyprus
Minerals  Company and was renamed Cyprus Amax Minerals Company in November 1993)
delineated a deposit of molybdenum containing approximately  146,000,000 tons of
mineralization averaging 0.43% molybdenum disulfide on the properties of USE and
Crested.

         Advance royalties are paid in equal quarterly installments,  until: (i)
commencement of production;  (ii) failure to obtain certain  licenses,  permits,
etc., that are required for production; or (iii) AMAX's return of the properties
to USE and Crested.  USECC did not receive any advance  royalties  during fiscal
1996 because of an arrangement with Cyprus Amax described below. These royalties
are shown in the  Consolidated  Statements of Operations as a component of gains
from  restructuring  mineral  properties  agreements.  See  "Note  F to the  USE
Consolidated  Financial  Statements."  The advance  royalty  payments reduce the
operating  royalties  (six  percent of gross  production  proceeds)  which would
otherwise be due from Cyprus Amax from  production.  There is no  obligation  to
repay the advance royalties if the property is not placed in production.

         The  Agreement  with AMAX also  provides  that USE and  Crested  are to
receive $2,000,000 (one-half to each), at such time as the Mt. Emmons properties
are put into  production  and,  in the  event  AMAX  sells its  interest  in the
properties,  USE and Crested would  receive 15 percent of the first  $25,000,000
received by AMAX. USE and Crested have asserted that the  acquisition of AMAX by
Cyprus Minerals  Company was a sale of AMAX's  interest in the properties  which
would  entitle USE and Crested to such  payment.  Cyprus Amax has rejected  such
assertion and USE and Crested are considering their remedies.

         In fiscal 1995, USE and Crested  reached  agreement with Cyprus Amax to
forego six quarters of advance royalties (starting fourth quarter calendar 1994)
as payment for the option  exercise  price for certain  real estate in Gunnison,
Colorado  owned by Cyprus Amax and the subject of a purchase  option held by USE
and Crested.  The option  exercise price is valued at $266,250.  USE and Crested
exercised  their option in August 1994 and  subsequently  sold that property for
$970,300  in cash and notes  receivable.  The advance  royalties  resumed in the
second  quarter of calendar  1996,  however,  the payment was not received until
June 1996,  being the first quarter of fiscal 1997. USE recognized  $211,000 and
$207,300  of revenues  in fiscal  1998 and 1997,  respectively,  related to this
royalty interest.

Molybdenum Market Information

         Molybdenum is a metallic  element with  applications in both metallurgy
and  chemistry.  Principal  consumers  include  the steel  industry,  which uses
molybdenum alloying agents to enhance strength and other  characteristics of its
products,  and the  chemical,  super-alloy  and  electronics  industries,  which
purchase molybdenum in upgraded product forms.

         The molybdenum  market is cyclical with prices influenced by production
costs and the rate of production of foreign and domestic  primary and by-product
producers,  world-wide economic  conditions  particularly in the steel industry,
the U.S. dollar exchange rate, and other factors such as the rate of consumption
of molybdenum in end-USE  products.  When molybdenum prices rose dramatically in
the late

                                       41

<PAGE>



1970s, for example, steel alloys were modified to reduce reliance on molybdenum.
AMAX and  Cyprus  Minerals  Company  were the two  major  primary  producers  of
molybdenum in the United States until November  1993,  when AMAX was acquired by
Cyprus.

         Worldwide  demand for molybdic  oxide in calendar  1996 was reported at
approximately  230,000,000  pounds, its highest level ever.  Production for that
period was about 225,000,000 pounds. There is, however, excess capacity from the
primary  molybdenum  mines which are currently not producing.  In addition,  by-
product molybdenum  (primarily from Chilean copper mining companies) has a major
impact on available supplies. It is unlikely that any major new primary deposits
will be developed during fiscal 1999.

         Molybdenum prices on the open spot market increased substantially, from
$3.35 per pound of technical  grade molybdic  oxide (the  principal  product) in
September 1994, to $15.50 - $17.50 per pound in February 1995.  However,  by May
31,  1996,  prices  declined to $3.00 - $3.35 per pound but were in the $4.00 to
$4.40 per pound range in September 1997 and $3.75 in July 1998.

Parador Mining (Nevada)

         USE and Crested are  sublessees  and assignees from Parador Mining Co.,
Inc. ("Parador"),  of certain rights under two patented mining claims located in
the Bullfrog Mining District of Nye County,  Nevada.  The claims are immediately
adjacent  to and  part of a gold  mine  operated  by Bond  Gold  Bullfrog,  Inc.
("BGBI"),  a non-affiliated  third party (now known as Barrick Bullfrog,  Inc.).
USE and Crested have also been assigned certain  extralateral  rights associated
with the claims and certain  royalty  rights  relating to a prior lease on those
properties.  The lease to USE and  Crested is for a ten year  primary  term,  is
subject to a prior lease to BGBI on the  properties,  and allows USE and Crested
to explore for,  develop and mine minerals  from the claims.  If USE and Crested
conduct  activities  on the claims,  they are  entitled to recover  costs out of
revenues from  extracted  minerals.  After  recovering  any such costs,  USE and
Crested will pay Parador a production  royalty of 50 percent of the net value of
production sold from the claims.

         USE,  Crested and Parador  presently are in litigation  concerning this
property. See "Legal Proceedings - BGBI Litigation" below.

Oil and Gas.

         Fort Peck Lustre Field (Montana). USECC conducts a small oil production
operations  at the  Lustre  Oil  Field on the Ft.  Peck  Indian  Reservation  in
north-eastern  Montana; four wells are producing,  and USE and Crested receive a
fee based on oil produced. USE is the operator of record. No further drilling is
expected in this field.  This fee and certain real  property of USE and Crested,
have been pledged or mortgaged as security for a $1,000,000  line of credit from
a bank.

Commercial Operations

         Brunton.  In  fiscal  1996,  USE  sold  The  Brunton  Company  to Silva
Production  AB, a closely held Swedish  corporation  ("Silva")  for  $4,300,000.
Brunton  is  engaged  in the  manufacture  and  marketing  of  professional  and
recreational outdoor products and at the time of its sale Brunton was 100% owned
by USE.

         USE received  $300,000 upon  execution  and delivery of the  Agreement,
approximately $3,000,000 by wire transfer from Silva at closing and an agreement
(promissory note) by Silva to pay USE $1,000,000 in three annual installments of
$333,333  each,  together  with  interest  at the  rate  of 7% per  annum,  such
installments to be paid on February 15, 1997, February 15, 1998 and February 15,
1999 The installments for 1997 and 1998 have been received.


                                       42

<PAGE>



         In  addition,  Silva  agreed to pay USE 45% of the net  profits  before
taxes derived from Brunton products and operations  (including new products then
being  developed  by  Brunton)  for a period  of four  years  and  three  months
commencing February 1, 1996. The profits payment for the period February 1, 1996
through April 30, 1997 of $292,600 was received  after May 31, 1997; the profits
payment for fiscal 1998 has not yet been received.

         Certain items of equipment  and personal  property were withheld by USE
from the Agreement and transferred from Brunton to USE, by mutual agreement with
Silva,  for USE's  assumption of the  indebtedness  thereon,  including  225,556
shares of USE's common stock,  and options to purchase  150,000  shares of USE's
common stock for $3.50 per share;  and 160,000  shares of Crested  common stock,
and options to purchase  (from  Crested)  300,000 shares of Crested common stock
for $0.40 per share. USE  subsequently  transferred to Plateau 125,556 shares of
USE (and  options to  purchase  75,000  shares of USE),  plus  60,000  shares of
Crested (and options to purchase  150,000 shares of Crested) in partial  payment
of debt owed to Plateau by USECC. The remaining  100,000 USE shares (and options
to purchase  75,000 USE  shares),  plus 100,000  Crested  shares (and options to
purchase  150,000  shares of Crested) were  transferred to SGMC. In fiscal 1998,
SGMC  exercised its USE options.  Plateau did not exercise its USE options,  and
neither SGMC or Plateau exercised their Crested options, which have expired.

         The  sale  eliminated  Brunton's   manufacturing  and/or  marketing  of
professional  and recreational  outdoor products from the commercial  segment of
USE's  business for fiscal 1997 and  thereafter,  except to the extent of future
net profit payments from Silva.

         Real  Estate  and  Other  Commercial   Operations.   USE  owns  varying
interests,  alone and with  Crested,  in  affiliated  companies  engaged in real
estate, transportation,  and commercial businesses. The affiliated organizations
include Western Executive Air, Inc. ("WEA") and Canyon Homesteads, Inc. (through
Plateau).  Activities of these and other  subsidiaries  in the business  sectors
include ownership and management of a commercial  office building,  the townsite
of Jeffrey City,  Wyoming and the townsite,  motel,  convenience store and other
commercial facilities in Ticaboo, Utah.

         Wyoming  Properties.  USECC owns a 14-acre tract in Riverton,  Wyoming,
with a  two-story  30,400  square foot office  building  (including  underground
parking). The first floor is rented to affiliates,  nonaffiliates and government
agencies;  the second  floor is occupied by USE and Crested and is adequate  for
their executive  offices.  The property is mortgaged to the WDEQ as security for
future reclamation work on the SMP Crooks Gap uranium properties.

         USECC  (through WEA) also owns a fixed base  aircraft  operation at the
Riverton Municipal  Airport,  including a 10,000 square foot aircraft hangar and
7,000  square feet of  associated  offices and  facilities.  This  operation  is
located on land leased from the City of Riverton for a term ending  December 16,
2005, with an option to renew on mutually  agreeable  terms for five years.  The
annual rent is presently  $1,180  (adjusted  annually to reflect  changes in the
Consumer  Price Index),  plus a $0.02 fee per gallon of fuel sold.  WEA owns and
operates an aircraft fixed base operation  with fuel sales,  flight  instruction
services and aircraft maintenance in Riverton, Wyoming.

         USE and Crested also own 18 undeveloped  lots on 26.8 acres of the Wind
River Airpark near the Riverton  Municipal  Airport,  and three  mountain  sites
covering 16 acres in Fremont County, Wyoming.

         USECC owns  various  buildings,  290 city lots and/or  tracts and other
properties at the Jeffrey City townsite in south-central  Wyoming.  Nearly 4,000
people  resided in Jeffrey City in the early 1980s,  when the nearby  Crooks Gap
and Big Eagle uranium mining projects were active.  The townsite may be utilized
for  worker  housing  as the  Jackpot  Mine  and  Sweetwater  Mill  are put into
operation. In the interim, USE and

                                       43

<PAGE>



Crested are selling lots at Jeffrey City and made sales aggregating  $38,400 and
$21,150 during fiscal 1998 and 1997, respectively.

         In Riverton,  Wyoming, USE owns five city lots and a 20-acre tract with
improvements  including two smaller office  buildings and three other  buildings
with 19,000  square feet of office  facilities,  5,000 square feet of laboratory
space and repair and maintenance shops containing 8,000 square feet.

         Colorado  Properties.  In connection with the AMAX  transaction for the
Mt. Emmons molybdenum properties near Crested Butte, Colorado, USECC acquired an
option  from AMAX  (now  Cyprus  Amax) to  purchase  approximately  57 acres for
$200,000 in Mountain Meadows Business Park, Gunnison,  Colorado. See "Minerals -
Molybdenum"  above.  The property is zoned  commercial  and  industrial,  and is
adjacent to Western State College.  In fiscal 1995, USECC and Cyprus Amax agreed
to  exercise  the option by USE and Crested  agreeing to forego six  quarters of
advance  royalties  from Cyprus Amax (the option  purchase  price was $200,000),
plus payment of certain  expenses i.e.  real property  taxes from 1987 and other
expenses  amounting to $19,358.  Thereafter,  USE (together with Crested) signed
option agreements with Pangolin  Corporation,  a Park City, Utah developer,  for
sale of the 57 acres, and a separate parcel owned in Gunnison County, Colorado.

         Although initial payments on the option  agreements were received,  the
developer  is in  default  on the  balance.  In July  1998,  USE filed a lawsuit
seeking  recovery of the balance owing on promissory  notes and  contracts.  See
"Legal Proceedings."

         Utah Properties.  Canyon Homesteads, Inc. (a Plateau subsidiary) owns a
majority  interest  in a joint  venture  which  holds the  Ticaboo  Townsite  in
Ticaboo,  Utah  (see  "Minerals  -  Uranium-Shootaring  Canyon  Mill  -  Ticaboo
Townsite"  above).  In fiscal 1995,  USE  acquired the minority  interest in the
joint venture from a nonaffiliate. Revenues from sale of homesites and operation
of the motel were nominal in 1998.

Construction

         Four  Nines  Gold,  Inc.  On  September  13,  1995,  FNG was  awarded a
construction  contract  for  $618,270  by the United  States  Department  of the
Interior,  Bureau of Reclamation,  for the Minor Laterals, North Canal, Stage 5,
Belle Fourche Unit,  South Dakota.  As of May 31, 1997 FNG had completed 100% of
the contract,  billing and receiving $618,270.  The contract as of May 31, 1997,
had  resulted in a loss of $48,426 to FNG,  however,  a claim for  $172,977  was
submitted. On July 2, 1998 the claim was denied by the Bureau of Reclamation and
FNG has 12 months to appeal.

         For fiscal 1998,  FNG has had no contracts for  construction  work, but
has  rented  its  equipment  to USECC for USE by the GMMV at the  Jackpot  Mine.
Rental revenues  totaled  $478,338 for fiscal 1998 at a profit of $263,409,  and
the rentals are continuing into fiscal 1999.

         Neither  commercial  nor  construction  operations are dependent upon a
single customer,  or a few customers,  the loss of which would have a materially
adverse effect on the Company.

Research and Development

         USE has incurred no research and  development  expenditures,  either on
its own account or sponsored by customers, during the past three fiscal years.

                                       44

Environmental

         General.  USE's  operations are subject to various  federal,  state and
local  laws and  regulations  regarding  the  discharge  of  materials  into the
environment  or  otherwise  relating  to  the  protection  of  the  environment,
including the Clean Air Act, the Clean Water Act, the Resource  Conservation and
Recovery Act ("RCRA"), and the Comprehensive Environmental Response Compensation
Liability  Act  ("CERCLA").  With  respect  to mining  operations  conducted  in
Wyoming, Wyoming's mine permitting statutes,  Abandoned Mine Reclamation Act and
industrial  development and siting laws and regulations also impact USE. Similar
laws and regulations in California affect SGMC,  operations and in Utah laws and
regulations effect Plateau's operations.

         USE's  management  believes  USE  is  currently  in  compliance  in all
material respects with existing  environmental  regulations.  To the extent that
production by SMP, GMMV or SGMC is delayed,  interrupted or discontinued  due to
need to  satisfy  existing  or new  provisions  which  relate  to  environmental
protection, future USE earnings could be adversely affected.

         Crooks  Gap.  An  inoperative  ion  exchange  facility  at  Crooks  Gap
currently holds a NRC license for possession of uranium  operations  byproducts.
USE has applied to the NRC for permission to decommission and  decontaminate the
plant,  dispose low level waste into the Sweetwater Mill tailings cell, and keep
intact  such of the  facility  as does  not  require  dismantling  and  which is
approved for unrestricted operation.

         Other   Environmental   Costs.   Actual  costs  for   compliance   with
environmental  laws may vary  considerably  from estimates,  depending upon such
factors as changes in environmental laws and regulation (e.g., the new Clean Air
Act), and conditions  encountered in minerals  exploration and mining.  USE does
not anticipate that expenditures to comply with laws regulating the discharge of
materials into the environment,  or which are otherwise  designed to protect the
environment,  will  have any  substantial  adverse  impact  on the  Registrant's
competitive position.

Employees

         As of the date of this Prospectus,  USE had  approximately 82 full-time
employees  (including  mine and mill  employees in Wyoming and Utah) compared to
175 before the Jackpot Mine on Green  Mountain was put on standby.  Crested uses
approximately  50 percent of the time of USE employees,  and reimburses USE on a
cost reimbursement basis.

Mining Claim Holdings

         Title to Properties.  Nearly all the uranium mining  properties held by
GMMV, USE and Plateau are on federal  unpatented  claims.  Unpatented claims are
located  upon  federal  public land  pursuant to  procedure  established  by the
General  Mining Law.  Requirements  for the  location of a valid mining claim on
public land  depend on the type of claim being  staked,  but  generally  include
discovery  of  valuable  minerals,  erecting a  discovery  monument  and posting
thereon a location  notice,  marking the boundaries of the claim with monuments,
and  filing a  certificate  of  location  with the  county in which the claim is
located and with the BLM. If the statutes and  regulations for the location of a
mining claim are complied with, the locator obtains a valid  possessory right to
the contained  minerals.  To preserve an otherwise  valid claim, a claimant must
also pay certain rental fees annually to the federal government  (currently $100
per  claim) and make  certain  additional  filings  with the county and the BLM.
Failure  to pay such fees or make the  required  filings  may  render the mining
claim  void  or  voidable.   Because  mining  claims  are   self-initiated   and
self-maintained,  they possess some unique  vulnerabilities  not associated with
other types of property interests. It is impossible to ascertain the validity of
unpatented  mining claims  solely from public real estate  records and it can be
difficult

                                       45

<PAGE>



or impossible to confirm that all of the requisite  steps have been followed for
location and  maintenance  of a claim.  If the validity of an unpatented  mining
claim is  challenged by the  government,  the claimant has the burden of proving
the present economic feasibility of mining minerals located thereon. Thus, it is
conceivable  that during times of falling metal prices,  claims which were valid
when located could become  invalid if  challenged.  Disputes can also arise with
adjoining property owners for encroachment or under the doctrine of extralateral
rights (see "Legal Proceedings - BGBI Litigation").

         Proposed  Federal  Legislation.  The U.S.  Congress has, in legislative
sessions  in recent  years,  actively  considered  several  proposals  for major
revision of the General  Mining Law,  which  governs  mining  claims and related
activities on federal public lands. If any of the recent  proposals  become law,
it could result in the imposition of a royalty upon  production of minerals from
federal  lands  and new  requirements  for  mined  land  reclamation  and  other
environmental  control measures. It remains unclear whether the current Congress
will pass such legislation and, if passed,  the extent such new legislation will
affect existing mining claims and operations.  The effect of any revision of the
General Mining Law on USE' operations  cannot be determined  conclusively  until
such revision is enacted;  however,  such legislation could materially  increase
the carrying costs of the Green Mountain mineral properties,  the SMP properties
and some of Plateau's mineral properties which are located on federal unpatented
mining claims,  and could increase both the capital and operating costs for such
projects and impair USE's ability to hold or develop such properties, as well as
other mineral prospects on federal unpatented mining claims.

                                LEGAL PROCEEDINGS

Sheep Mountain Partners Arbitration/Litigation

         In 1991,  disputes arose between  USE/Crested,  and Nukem, Inc. and its
subsidiary Cycle Resource  Investment Corp.  ("CRIC"),  concerning the formation
and operation of the Sheep Mountain Partners  partnership for uranium mining and
marketing,  and activities of the parties outside SMP.  Arbitration  proceedings
were  initiated  by CRIC in June 1991 and in July  1991,  USECC  filed a lawsuit
against  Nukem,  CRIC  and  others  in the  U.S.  District  Court  (District  of
Colorado).  Later,  USECC filed  another  suit for the standby  costs at the SMP
mines against SMP in the Colorado State Court. The Federal Court stayed both the
arbitration  proceedings  and the State Court case. In February 1994, all of the
parties agreed to exclusive and binding  arbitration of the disputes  before the
American  Arbitration  Association  ("AAA"),  for which the legal claims made by
both sides included fraud and misrepresentation,  breach of contract,  breach of
duties owed to the SMP partnership, and other claims.

         Following 73 hearing days and various  submissions by the parties,  the
AAA panel (the  "Panel")  entered an Order and Award (the "Order") in April 1996
finding  generally  in favor  of USE and  Crested  on  certain  of their  claims
(including the claims for  reimbursement  for standby  maintenance  expenses and
profits  denied SMP in Nukem's  trading of uranium),  and in favor of Nukem/CRIC
and against USE and Crested on certain other claims.

         Approximately  $18  million of SMP cash had been placed in escrow and a
bank account by agreement of the parties pending resolution of the disputes.

         The April  1996  Order  awarded  USE and  Crested  monetary  damages of
approximately  $7,800,000  with interest  (after  deduction of monetary  damages
which the  Arbitration  Panel awarded in favor of Nukem/CRIC and against USE and
Crested).  An additional  amount of approximately  $4,300,000 was awarded by the
Panel to USE and  Crested,  to be paid out of the  escrowed  $18 million and SMP
cash.  This  $4,300,000 was USE and Crested's  share of SMP profits from selling
uranium to utilities  and  advances to purchase  uranium for SMP. The Panel also
ordered that one utility supply  contract which had been in dispute  belonged to
SMP,  not Nukem,  and that Nukem was to assign that  contract to SMP.  The Panel
further ordered

                                       46

<PAGE>



that certain contracts which Nukem had obtained for the purchase of uranium from
countries in the CIS (former Soviet republics) belonged to SMP.

         After motions and further  proceedings in the Federal  District  Court,
and a  reaffirmation  Order by the Panel in July 1996,  the U.S.  District Court
confirmed  the  Panel's  Order and  Award.  In  November  1996,  USECC  received
$4,367,000 of the damage award out of the SMP escrowed  funds and a separate SMP
bank account. In confirming the Panel's Order, the Court ordered Nukem to assign
a utility contract to SMP; to pay USECC a net amount of approximately $8,465,000
in  monetary  damages;  and  impressed a  constructive  trust in favor of SMP on
Nukem's rights to purchase CIS uranium,  the uranium acquired  pursuant to those
rights,  and  profits  therefrom.  Nukem/CRIC  posted  a  supersedeas  bond  for
$8,613,600  and the Court  stayed  execution on the  judgment.  The bond did not
cover the value of the CIS  contracts at issue because the Panel's Order did not
value such contracts.

         Nukem/CRIC appealed the District Court's Second Amended Judgment to the
10th Circuit Court of Appeals. The appeal was argued before the Court of Appeals
on September 24, 1998.

         During the fourth quarter of fiscal 1998, USE and Crested  entered into
a partial settlement with Nukem and CRIC on certain of the claims not on appeal.
Under the partial  settlement,  USECC received (i) from SMP an assignment of all
of the mining  claims and  equipment  which had been held by SMP (USECC  remains
responsible  for the reclamation  liabilities  associated with the claims as had
always been the case when the properties were in SMP); (ii) from Nukem and CRIC,
$484,361  which settled USE and  Crested's  claim to their share of the past and
future profits on a utility  contract which Nukem had wrongfully kept outside of
SMP (and Nukem was  allowed to keep this  contract  as part of the  settlement);
(iii) from Nukem and CRIC, $4,540,000 to settle all claims by USE against Nukem,
CRIC and SMP (including  Nukem/CRIC's one-half share of the SMP mine maintenance
costs); (iv) from SMP, a contract to sell 1,076,842 pounds of uranium oxide to a
utility;  and (v) from SMP, a contract  to  purchase  600,000  pounds of uranium
oxide from another  producer in North America  (200,000 pounds annually  through
2000).  In connection  with the partial  settlement,  the parties  agreed to the
dismissal  with  prejudice of the Colorado and Wyoming  State Court  proceedings
(for reimbursement of SMP mine maintenance costs), and all claims in the Federal
District  Court and the  arbitration,  except for the issues  pending before the
10th Circuit Court of Appeals.  The cash settlement portion under (iii) above is
in addition to the $4,367,000  received by USECC in November 1996 out of the SMP
escrowed funds.

         In  September  1998,  USECC sold the purchase  contract  ((v) above) to
Nukem for $35,000  for each three  years  wherein  Nukem buys  uranium  from the
producer;  if Nukem doesn't purchase any uranium in any year, no payment is owed
to USECC for that year.

         A three  judge  panel of the 10th  Circuit  Court of Appeals  issued an
Order and Judgment in the  Nukem/CRIC  arbitration/litigation  matter on October
22, 1998, which  unanimously  affirmed the Federal District Court Second Amended
Judgment.  The  ruling of the 10th  Circuit  Court of Appeals  affirmed  (i) the
imposition of a constructive trust in favor of SMP on Nukem's rights to purchase
CIS uranium,  the uranium  acquired  pursuant to those  rights,  and the profits
therefrom;  and (ii) the damage  award  against  Nukem/CRIC.  As a result of the
Court of Appeals  ruling,  USE and  Crested  received an  additional  $6,077,264
(including interest and court costs) from Nukem in February 1998 for a total net
monetary  award of  $15,468,625  in the  arbitration/litigation,  and  equitable
relief in the form of USE's  and  Crested's  interest  in SMP,  which  holds the
constructive trust over the CIS contracts. However, the value of the interest in
SMP cannot be determined  until a full  accounting  of those  contracts has been
completed by SMP. The length of time such an accounting  will require  presently
cannot be estimated.

Ticaboo Townsite Litigation.

         In fiscal 1998, a prior contract operator of the Ticaboo restaurant and
lounge,  and two employees  supervising the motel and convenience  store in Utah
(owned by Canyon  Homesteads,  Inc.) sued USE,  Crested and others in Utah State
Court.  After a five  day  trial,  a jury  denied  the  claims  of two of  three
plaintiffs but awarded the third plaintiff  $156,000 in damages against USE. USE
has filed motions  including a motion for judgment  notwithstanding  the verdict
("JNOV"). The motions were denied by the Court and USE posted a supersedeas bond
for $275,000 to appeal the judgment. The appeal is pending.

BGBI Litigation

         USE and Crested are  defendants  and  counter-  or  cross-claimants  in
certain  litigation in the District Court of the Fifth Judicial  District of Nye
County,  Nevada,  brought by Bond Gold Bullfrog Inc.  ("BGBI") on July 30, 1991.
BGBI (now known as Barrick  Bullfrog,  Inc.) is an affiliate of Barrick Corp., a
large  international  gold  producer  headquartered  in  Toronto,   Canada.  The
litigation  primarily concerns  extralateral rights associated with two patented
mining claims owned by Parador  Mining  Company Inc.  ("Parador")  and initially
leased to a  predecessor  of BGBI,  which  claims are in and  adjacent to BGBI's
Bullfrog open pit and underground mine. USE and Crested assert certain interests
in the claims under an April 1991  assignment  and lease with Parador,  which is
subject to the lease to BGBI's predecessor.

         BGBI seeks to quiet  title to its  leasehold  interest  in the  subject
claims, a determination  that USE and Crested have no rights in the claims,  and
an order  enjoining USE and Crested from  asserting  any interest in them.  BGBI
further asserts other claims and that, in attempting to lease an interest in the
subject claims to USE and Crested,  Parador breached the provisions of its lease
to BGBI, and that Parador is  responsible  for the legal fees and costs incurred
by BGBI in the quiet title action, which may be offset against royalties.

         A partial or bifurcated trial to the Court of the  extralateral  rights
issues was held on December 11 and 12, 1995,  to determine  whether the Bullfrog
orebody is a "vein,  lode or ledge" as described in the General  Mining Law and,
if so,  whether the facts warrant  application  of the doctrine of  extralateral
rights as set forth in such statute.  The Court found that Parador had failed to
meet its burden of proof and therefore  Parador,  USE and Crested have no right,
title and interest in the minerals lying beneath the claims of Layne pursuant to
extralateral  rights.  The partial trial did not address the issues of breach of
contract by the defendants and BGBI for specific performance and they were tried
before the Court  commencing  on January 26,  1998.  After the trial,  the Court
found  against the parties on their  respective  claims.  BGBI and Parador,  and
USE/Crested are appealing the decision to the Nevada Supreme Court.

Department of Energy Litigation

         On July 20, 1998, eight uranium mining companies with operations in the
United  States  (including  USE,  Crested,  YSFC) and the Uranium  Producers  of
America (a trade  organization)  filed a  complaint  against  the United  States
Department  of Energy  (the  "DOE")  in a  lawsuit  (file no. 98 CV 1775) in the
United States District Court, Cheyenne, Wyoming. The complaint seeks declaratory
judgment and injunctive  relief. The plaintiffs allege that the DOE violated the
USEC  Privatization  Act of 1996, when the DOE transferred 45 metric tons of low
enriched  uranium  and 3,800  metric  tons of natural  uranium to United  States
Enrichment Corp.  ("USEC").  See "Business and Properties - Uranium  Marketing -
USEC Inc." above.

         Specifically,  the plaintiffs  allege that the USEC  Privatization  Act
authorizes  the DOE to  transfer to USEC  "without  charge" an initial 50 metric
tons of highly enriched  uranium and 7,000 metric tons of natural  uranium.  The
Act authorizes the DOE to sell (not merely  transfer)  additional  quantities of
uranium out of the DOE stockpile, but only upon payment of fair market value for
the  uranium  and then only upon  specific  finding  by the DOE that such a sale
would not have an adverse material impact on the domestic uranium,

                                       48

<PAGE>



mining,  conversion or enrichment industry,  taking into account sales under the
Russian HEU Agreement and the Suspension Agreement.

         The  plaintiffs  have  asked  the  Court  to  declare  that (i) the DOE
violated its statutory  authority by  transferring  uranium to USEC in excess of
statutory  limits on volume;  (ii) the excess amounts were not "sold" by the DOE
to USEC for fair value, as required by the Act, and mandated findings by the DOE
concerning  possible  adverse  impacts were not supported in fact; and (iii) the
DOE be enjoined  from future  transfers in violation of the Act. The DOE filed a
motion to dismiss the  complaint  claiming that the U.S.  Congress  withdrew its
consent to be sued in connection with the USEC Inc.  privatization and that USEC
Inc.  must be joined as an  indispensable  party.  The State of Wyoming moved to
join in the  litigation on behalf of the  plaintiffs.  A hearing was held on the
motions on January 8, 1999 before the U.S.  District Court in Cheyenne,  Wyoming
and the Court took the motions under advisement.

Contour Development Litigation

         On July 28,  1998,  USE filed a lawsuit in the United  States  District
Court, Denver, Colorado against Contour Development Company, L.L.C. and entities
and persons  associated  with Contour  Development  Company,  L.L.C.  (together,
"Contour") and the original developer Pangolin Corporation, seeking compensatory
and  consequential  damages of more than $1.3  million from the  defendants  for
dealings in real estate owned by USE and Crested in Gunnison, Colorado.

         Specifically,  USE  (which is the  assignee  of  Crested's  rights  and
interests in certain of the promissory notes,  contracts and agreements) alleges
that Contour has breached contracts for the sale of USE's and Crested's Gunnison
properties,  and is in default on the promissory  notes delivered to pay for the
Gunnison  properties.  USE has further alleged that Contour fraudulently induced
USE and  Crested  to  enter  into  restructuring  agreements  for  the  original
transactions between the parties in such properties;  and further,  that Contour
has breached the duties of good faith, honesty, full disclosure and fair dealing
which were owed to USE and Crested by Contour in the course of the transactions.
USE has made  additional  claims  against  Contour  for  unjust  enrichment  and
conversion of the real estate assets and added additional parties as defendants.
See  "Business  -  Commercial  Operations  - Real  Estate  and Other  Commercial
Operations - Colorado Properties" above.

         As of the date of this  Prospectus,  the parties are  negotiating for a
settlement, however, no final settlement has been reached.

SGMC Litigation

         In 1993, Amador County issued a conditional use permit ("CUP") to allow
SGMC  to  develop  the SGM  near  the  town  of  Sutter  Creek,  Amador  County,
California.  A number of  conditions  were  attached to the  original  CUP which
accommodated  local citizen and government  agency  concerns about noise,  waste
disposal, traffic and other aspects of the proposed mining operation.

         In 1997 and 1998, SGMC proposed  amendments to the CUP for a new design
of the SGM which  would  lower its  environmental  impact by  reducing  traffic,
potentially  eliminating  the use of cyanide  on-site,  and  removing  two large
tailings  dams which would have been built to hold mine and mill waste.  The new
design  also would  significantly  reduce  capital and  operating  costs for the
mine/mill  complex,  but cover more land for waste disposal and other  purposes.
The certification  and approval by the Amador County Planning  Commission of the
Final  Subsequent  Environmental  Impact Report  ("FSEIR") and CUP amendments on
July 14, 1998 was appealed (by another local citizens project  opposition group)
to the Amador County Board of  Supervisors.  In August and September  1998,  the
Board of Supervisors certified the FSEIR and approved the amendments to the CUP.

                                       49

<PAGE>



         On  September  28, 1998 a lawsuit was filed in Amador  County  Superior
Court,  California (Case No. 98 CV 3298) by Concerned  Citizens of Amador County
as  plaintiffs,  against  the County of Amador and the  Amador  County  Board of
Supervisors,  and  against  SGMC  as a  real  party  in  interest.  The  lawsuit
challenges  the  actions  of  Amador  County  and its  Board of  Supervisors  in
certifying  the  FSEIR  and  approving  the  amended  CUP.   Specifically,   the
petitioners   allege  that  the  FSEIR  is  inadequate   under  the   California
Environmental  Quality Act  ("CEQA"),  and further,  that Amador  County and its
Board of  Supervisors  did not follow the fact  finding,  publication  and other
procedures mandated by CEQA and local land use ordinances.  The petitioners have
requested  the court to void the FSEIR,  rescind the amended CUP, and not permit
Amador  County to take further  actions to allow  implementation  of the Lincoln
Project  until a revised  EIR is  completed  and local land use  ordinances  are
revised or complied with.

         SGMC has filed an answer to the petition, denying the allegations that:
there are substantive  deficiencies in the FSEIR; or that important steps in the
analysis,  approval and public comment processes as required under CEQA were not
followed in approving the FSEIR and amended CUP.

         SGMC  anticipates  the  lawsuit  could  possibly  delay  the  start  of
operations at the Lincoln  Project.  SGMC does not  anticipate  that the lawsuit
will result in the  ultimate  cancellation  of the Lincoln  Project,  or prevent
implementation  of the more efficient and less  expensive  (and  environmentally
improved) Lincoln Project as contemplated by the amended CUP.

         USE has not paid any cash  dividends  with respect to the Common Stock.
There are no contractual  restrictions on USE's present or future ability to pay

                    USE MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

         The  following  is  Management's   Discussion  and  Analysis  of  those
significant  factors which have affected USE's liquidity,  capital resources and
results of operations during the periods covered in USE's Consolidated Financial
Statements filed with this Prospectus.

         Some of the  statements in this  Management's  Discussion  and Analysis
constitute  "forward-looking  statements"  within  the  meaning  of the  Private
Securities  Litigation  Reform Act of 1995.  Such  forward-  looking  statements
involve known and unknown risks,  uncertainties and other factors that may cause
the  actual  results,  performance  or  achievements  of  USE  to be  materially
different  from any future  results,  performance or  achievements  expressed or
implied by the forward-looking statements.

Liquidity and Capital Resources at November 30, 1998

         During the six months ended  November 30, 1998,  USE and its subsidiary
Crested received $5,026,000 in cash as a result of a partial settlement of Sheep
Mountain Partners ("SMP") arbitration.  Primarily as a result of receiving these
funds the cash position of USE increased to $5,900,800 at November 30, 1998 from
$5,650,500 at May 31, 1998.  Other  increases in  components of working  capital
were  increases  in assets  held for resale  and other  assets of  $155,800  and
accounts receivable affiliates of $356,400.
 The  components  of the increase in assets held for resale and other assets was
an increase of $134,400 in prepaid insurance and $21,400  improvements in assets
held for sale by USE's subsidiary Plateau Resources Ltd.  ("Plateau").  Accounts
receivable  affiliates  increased due to USE and Crested advancing funds for the
Green Mountain Mining Venture  ("GMMV")  operations.  These advances had not yet
been reimbursed by the GMMV at November 30, 1998, due to certain  differences of
opinion between the GMMV  participants  relating to allowable  charges under the
temporary  standby status of the GMMV  properties.  As of December 31, 1998, the
majority  of these  advances  had been  repaid by the  GMMV.  USE,  Crested  and
Kennecott  continue  to work on  resolving  the balance of the funds due USE and
Crested.  Inventories also increased by $38,700 as a result of operational needs
of USE's subsidiaries Plateau and Western Executive Air, Inc.

         The current  portion of long term debt increased by $114,800 during the
six  months  ended  November  30,  1998,  as a result of  financing  the  annual
insurance  premium.  Total long term debt as a result of the  financing of these
insurance premiums along with other minor financings  resulted in an increase of
$201,000 in long term debt. During the six months ended November 30, 1998, there
was also a reduction of long term debt  through cash  payments of $160,700 for a
net increase in long term debt of $40,300.

         During the six months ended November 30, 1998, USE and its consolidated
subsidiaries  purchased  a various  pieces of  mining  equipment  for a total of
$188,600.  In the  normal  course of  evaluating  equipment  needs,  USE and its
subsidiary also received $203,900 in proceeds from the sale of various pieces of
equipment that were no longer needed.

         During the six months ended November 30, 1998, USE purchased a total of
45,700 shares of its Common Stock from the open market at a total purchase price
of $123,800. These shares are held as treasury shares.

         As part of the 1997 agreement to purchase  Kennecott's  interest in the
GMMV, USE and Crested received a $4,000,000 payment. This amount is carried as a
deferred purchase option until such time as an

                                       51

<PAGE>



acquisition  of the  Kennecott  interest is  concluded  (which would be on terms
different from the original 1997  Acquisition  Agreement),  or standby costs are
offset against the $4,000,000  deferred  purchase  option until it is reduced to
zero.

Capital Resources

         General:  The  primary  source  of  USE's  capital  resources  for  the
remaining  six months of fiscal 1999 are the cash on hand at November  30, 1998;
the potential  receipt of cash from the SMP Arbitration  Award;  possible equity
financing from affiliated companies; and proceeds under the line of credit after
it is renewed.  Additionally,  USE and Crested  will  continue to offer for sale
various non-core assets such as lots and homes in Ticaboo,  real estate holdings
in Wyoming, Colorado and Utah, and mineral interests.  Interest, rentals of real
estate holdings and equipment, aircraft chartering and aviation fuel sales, also
will provide cash.

         Line of Credit:  USE and Crested have had a  $1,000,000  line of credit
with a  commercial  bank.  The line of credit was secured by various real estate
holdings  and  equipment.  USE and Crested are  currently  negotiating  with the
commercial  bank to increase the line of credit.  No assurance can be given that
the line of credit will be  increased.  The  commercial  bank  however has given
initial  indications that at a minimum the line of credit will be renewed in its
initial amount of $1,000,000  during the third quarter of 1999, and possibly for
up to  $2,500,000.  It is  anticipated  that the line of  credit  may be used to
finance short term working capital needs.

         Financing: Equity financing for Sutter Gold Mining Company ("SGMC") and
Plateau Resources Ltd. ("Plateau") are dependent on the market price of gold and
uranium among other  conditions.  As of November 30, 1998,  the prices for these
metals  remained  depressed and it is not known when they will recover.  USE and
Crested continue to be optimistic concerning the future markets for these metals
but can not  accurately  forecast  what the prices  will be in the short or long
term  markets.  If the price for these metals do not increase in the short term,
working  capital  will  be  impacted  negatively  due to  holding  costs  of the
properties and the ability to raise equity funding could be impaired.

         Summary:  USE  believes  that cash on hand at November 30, 1998 and the
anticipated  proceeds from the Nukem litigation will be adequate to fund working
capital requirements through fiscal 1999. However,  these capital resources will
not be  sufficient  to provide  the  funding for major  capital  expansions  and
development of mineral properties. For these expansions USE and Crested continue
to seek joint venture partners.

Capital Requirements

         General:  The primary  requirements  for USE's working  capital  during
fiscal  1999 are  expected  to be the  costs  associated  with  the  development
activities  of  Plateau,  care and  maintenance  costs of the former SMP mineral
properties,  payments of holding fees for mining  claims,  USE's  portion of the
costs associated with the GMMV properties should USE elect to participate in the
holding costs, and corporate general and administrative expenses.

         SGMC: USE owns a majority interest in SGMC and is therefore potentially
responsible  for  the  ongoing  administrative  and  development  costs  of  the
properties  owned by SGMC.  USE is  therefore  assisting  SGMC in its efforts to
secure  financing to place the properties into  production.  SGMC has sufficient
cash reserves to fund its ongoing permitting and administrative  expenses. It is
anticipated that an additional $15 million is needed to complete the development
of the mine and  construction of the  cyanide-flotation  mill. Prior to the time
that such  construction  and development  costs are undertaken SGMC will require
either additional debt or equity financing.


                                       52

<PAGE>



         Due  primarily to the  sustained  decline in gold prices  during fiscal
1998,  USE  recorded a  $1,500,000  impairment  on its  investment  in SGMC.  If
financing is not obtained in fiscal 1999 and/or gold prices further decline from
present levels, USE will reevaluate the need for an additional impairment on its
investment in SGMC, which includes the Stock Purchase Warrant that is contingent
on SGMC identifying ounces of gold in excess of 300,000 ounces. USE acknowledges
that it may be  required  to record a  significant  impairment  under  Generally
Accepted  Accounting  Principles  should  financing  not be  obtained by SGMC to
develop  the  project or if gold prices  decline  further.  As of the six months
ended November 30, 1998, USE was continuing its search for  development  capital
and has several interested  parties,  however no financing  commitments has been
obtained.

         SMP:  As part of a  settlement  agreement  reached  during  the  fourth
quarter of 1998, the SMP mines and associated properties were transferred to USE
and Crested.  The holding and  reclamation  costs  associated  with these mining
properties  are  the  responsibility  of USE  and  Crested.  The  holding  costs
historically have been approximately $85,000 per month. USE and Crested continue
to search for improved  techniques  that will reduce these  monthly  costs.  The
future reclamation costs on the SMP properties are covered by a reclamation bond
which is secured by the pledge of certain real estate assets.  The dollar amount
for the reclamation bond is reviewed annually by State regulatory agencies.  USE
and Crested  currently  have a  reclamation  liability on the SMP  properties of
$1,451,800  which is shown as such in the long  term  liability  section  of its
balance sheet.

         It is not  anticipated  that the SMP  properties  will be  placed  into
production  during  fiscal 1999.  USE and Crested have  determined  that the SMP
mining properties should be maintained and prepared for production in the future
when the price of uranium increases into the $15 per pound range or at such time
as USE and  Crested  are  able to  obtain  long  term  delivery  contracts  with
favorable  price terms and the Sweetwater  Mill,  which is owned and operated by
the GMMV, is placed into operation.  There are no major reclamation  obligations
during  the  balance  of Fiscal  1999 that USE and  Crested  are aware of on the
properties.

         In  addition  to  receiving  the  SMP  mining  properties  back  in the
settlement  of a portion of the SMP  arbitration  issues,  USE and Crested  also
received  one of the market  related  delivery  contracts  which had  previously
belonged to SMP. There will be one delivery under this contract during the third
quarter of fiscal 1999,  which  requirement  was sold to a third party;  USE and
Crested will make a nominal profit on the sale during the third quarter of 1999.
As of November 30, 1998, USE has no additional delivery or financing commitments
for the sale or purchase of uranium during Fiscal 1999.

         GMMV:  During  July 1998,  the GMMV  Management  Committee  unanimously
agreed to place the Jackpot Mine and Sweetwater  Mill on active standby  status.
This  decision was made as a result of  uncertainties  in the short term uranium
market.  These same  uncertainties  made the  financing  of the  acquisition  of
Kennecott's  interest  in the GMMV more  difficult.  USE and  Crested  had until
October 30,  1998 to  complete  the  financing  efforts to purchase  Kennecott's
interest.  The financing  was not  successfully  completed  and the  Acquisition
Agreement, which was signed on June 23, 1997, expired on October 30, 1998.

         The mines  and the mill will  continue  to be  maintained.  Kennecott's
obligation  to fund the first $50 million in  expenditures  is now satisfied and
USE and Crested will be obligated  to fund their 50% of the ongoing  costs.  The
Management  Committee  of  the  GMMV  is  currently  discussing  what  level  of
expenditures  should be made to maintain  the  properties.  A final  decision on
these  expenditures  has not been  reached,  but USE,  Crested and Kennecott are
desirous  that the  expenses be held to a minimum.  All parties to the GMMV will
need to elect to either  participate  in the standby costs or become  diluted by
not participating.

         Certain  disagreements  as to how the  holding  costs  from  July  1998
forward are to be funded have  existed  between  Kennecott  and USE and Crested.
Until such time as the  disagreements  are resolved and a firm  understanding is
arrived at, no estimate as to any potential financial commitment for the holding
costs

                                       53

<PAGE>



of the properties to USE and Crested can be made. If the GMMV  participants  are
not able to resolve the  disagreements  on holding  cost  obligations,  the GMMV
contracts direct such disagreements to arbitration for resolution.

         Plateau:  Plateau  owns  and  operates  the  Ticaboo  townsite,  motel,
convenience store and restaurant.  Additionally,  Plateau owns and maintains the
Tony M uranium mine and  Shootaring  uranium mill. USE and Crested are currently
working  to obtain  the  necessary  permits  from the State of Utah to place the
Shootaring  mill into  production.  USE and Crested  are seeking  debt or equity
financing  of between $6 million  and $9 million to put the mill and Tony M mine
into  production.  Until such time as the  financing is received and  profitable
contracts are  obtained,  USE and Crested will not put the  properties  owned by
Plateau  into  production.  Historically,  the net holding  costs of the Plateau
properties have been $70,000 per month.

         During the six months ended November 30, 1998 the reclamation liability
on the Plateau properties was increased by $82,100 to provide for estimates made
by regulatory  agencies.  USE does not anticipate placing the Plateau properties
into production  during Fiscal 1999. It is also anticipated that the reclamation
liabilities,  (fully  bonded  by a cash  bond),  which are  associated  with the
Plateau properties will not be performed until well into the future.

         Yellow  Stone  Fuels  Corp.  ("YSFC"):   In  USE's  opinion,  YSFC  has
sufficient  cash to  complete  its  projected  1999  exploration  program on its
in-situ uranium  properties.  As of November 30, 1998, YSFC owed USE and Crested
$400,000 in a convertible  promissory  note plus interest at 10% per annum.  The
note was not paid on the due date of December  31, 1998.  The  directors of YSFC
and  management of USE and Crested are  discussing how the note will be retired.
Presently, it is anticipated that the note will be retired partially in cash and
partially  in  stock  of YSFC  pursuant  to the  terms  of the  note and will be
completely retired by these two methods during March of 1999. Additional amounts
of money totaling  $157,800 have been advanced by USE and Crested for YSFC for a
total indebtedness at November 30, 1998 of $577,800 plus accrued interest.  YSFC
has sufficient cash on hand to retire this indebtedness.

         Term Debt:  Debt to third  parties at November 30, 1998 was $544,200 as
compared to  $503,900 at May 31,  1998.  The  increase in debt to third  parties
consists primary of debt due on the financing of annual  insurance  premiums and
various purchases of equipment.

         Reclamation  Obligations:  It is not  anticipated  that  any  of  USE's
working  capital will be used in fiscal 1999 for the  reclamation  of any of its
mineral property  interests.  The reclamation costs are long term and are either
bonded through the USE of cash bonds or the pledge of assets. Further, it is not
anticipated  that any of the mining  properties in which USE owns an interest in
will enter the reclamation phase prior to May 31, 1999.

         Other:  USE and Crested  currently are not in production on any mineral
properties,   and   development   work  continues  on  several  of  their  major
investments.  USE and  Crested  are not  using  hazardous  substances  or  known
pollutants  to any great  degree in these  activities.  Consequently,  recurring
costs for managing hazardous substances, and capital expenditures for monitoring
hazardous substances or pollutants,  have not been significant.  USE and Crested
are also not aware of any claims for  personal  injury or  property  damage that
need to be accrued or funded.

         The tax years  through May 31, 1992 are closed  after audit by the IRS.
On October 5, 1998 USE and  Crested  met with the  Appeals  Office of the IRS in
Denver,  Colorado to discuss  resolving  issues raised for fiscal 1993 and 1994.
USE and Crested have  resolved all  outstanding  issues for those years  without
incurring any cash  commitments  for additional  taxes due. The IRS is currently
concluding  its review of fiscal  1995 and 1996 for the  companies  but no final
reports have been issued so no representations  can be made as to their ultimate
outcome.

Results of Operations

Six Months Ended November 30, 1998
Compared to Six Months Ended November 30, 1997

         During the six months ended November 30, 1998,  revenues decreased from
those  revenues  reported  during  the  same  period  of the  previous  year  by
$1,151,200 to total revenues of $3,012,600.  The major reduction was as a result
of USE not receiving any revenues from the delivery of uranium on one of the SMP
contracts.  During  the six months  ended  November  30,  1997,  USE  recognized
$969,100 in revenue from the profits  derived from a SMP contract  delivery.  No
such revenues  were  recognized  during the six months ended  November 30, 1998.
Revenues from  management  fees increased by $44,700 during the six months ended
November  30,  1998  over  the  same  period  of the  previous  year as a result
increased expenditures at the GMMV on which USE recognized a management fee.

         Costs and expenses for the six months ended November 30, 1998 increased
by $2,649,800  over the same period of the previous  year. The increase in costs
primarily  came  as a  result  of  increased  activity  on  mineral  properties,
associated with development of the Jackpot Mine declines in June and July on the
GMMV properties and subsequent shut down expenses of the GMMV properties, Sutter
Gold  permitting  and Plateau  permitting of mine and mill  properties  and real
estate   development.   Commercial   operations   and   increased   general  and
administrative  overhead to supervise the increased activity also contributed to
increased  general and  administrative  costs.  USE and  Crested  also paid cash
bonuses of $561,000  (including  taxes due) to four  employees in recognition of
the  extraordinary   dedication  they  had  given  to  their  work  in  the  SMP
arbitration/litigation.  The projects which are being  developed,  are currently
not in the production phase and therefore are not generating cash flow. With the
decline  in the  market  price  of  uranium,  it is  not  anticipated  that  the
properties will be placed into production in fiscal 1999. A decision was however
made in July 1998 to place the GMMV mines on active  standby.  USE is  therefore
anticipating reductions in costs.

         As a result of the  reduced  revenues  and  increased  costs  discussed
above,  operations for the six months ended November 30, 1998 resulted in a loss
of  $3,244,700 or $0.42 per share as compared to a loss of $174,000 or $0.03 per
share for the quarter ended November 30, 1997.

Year 2000 Issue

         Computer  programs  written in the past  utilize a two digit  format to
identify the applicable  year. Any date sensitive  software  beyond December 31,
1999 could fail, if not modified. The result could be among other possibilities,
disruptions  to  the   operations   and  the  inability  to  process   financial
transactions.  USE has evaluated the operating  systems on all  headquarter  and
field office  computers  and  consulted  with all of the vendors of the computer
software which is being used by USE and  affiliates.  The vendors have confirmed
to USE  that  all of USE's  software  and  information  systems  are  Year  2000
compliant.  There are no pieces of  equipment  in the  field  which  operate  on
imbeded computer chips.

Liquidity and Capital Resources at May 31, 1998

         Working  capital   increased  by  $5,231,900   during  fiscal  1998  to
$8,238,900  at May 31,  1998 from  $3,007,000  as of May 31,  1997.  The primary
components  of  the  increase  are  increases  in  cash  and  cash  equivalents,
litigation  settlement  receivable,  and accounts  receivable from affiliates of
$4,233,600,  $5,026,000, and $687,400,  respectively. These increases in working
capital were offset by increases in accounts payable, the deferred GMMV purchase
option and the current  portion of long term debt of  $523,800,  $4,000,000  and
$144,400, respectively.

         Cash increased due to the reconsolidation of Sutter Gold Mining Company
which resulted in increased cash of $3,124,000,  and $1,800,500 from the sale of
USE's common stock. These receipts of cash were used

                                       55

<PAGE>



primarily  in  mine  development  of  $1,125,000,   purchases  of  equipment  of
$1,947,200,  increased  investment in  affiliates of $102,300,  and cash used in
operations.  During the  fourth  quarter  of 1998 USE and  Crested  were able to
negotiate a settlement of certain of the issues in the Sheep  Mountain  Partners
("SMP") arbitration with Nukem and CRIC which resulted in settlement proceeds to
USE and Crested of $5,026,000. The increase in accounts receivable affiliates is
primarily the result of USE advancing funds for Crested in the various  ventures
in which the  companies  participate  and advances  that USE and Crested made on
behalf of Yellow Stone Fuels Corp.

         Accounts payable  increased due to the increased  activity of the Green
Mountain Mining Venture ("GMMV") where USE and Crested acted as the operator for
the  development  of the two decline  tunnels to access the uranium  mineralized
material on Green Mountain. The current portion of long term debt increased as a
result of a balloon payment coming due on one of USE's long term notes payable.

          During the first quarter of fiscal 1998, USE and Crested  entered into
an Acquisition  Agreement with Kennecott to acquire Kennecott's  interest in the
GMMV. As part of that Agreement  Kennecott paid USE and Crested  $4,000,000 upon
execution  which  is  recorded  as  a  deferred  purchase  option.  Because  the
Acquisition Agreement was not closed, the $4,000,000 will be applied against any
future reimbursable  costs/contributions due the GMMV. After these costs and any
remaining obligations are satisfied,  the remainder,  if any, will be recognized
as income.

         Investments in affiliates decreased by $4,127,800 primarily as a result
of  reconsolidating  SGMC and equity losses from  affiliates  of $3,179,600  and
$575,700,  respectively.  Restricted  investments  increased  as a result  of an
investment by SGMC in a non  affiliated  company for $53,400 and the increase of
the  certificates  of deposit  held by Plateau  Resources  Ltd.  ("Plateau")  of
$326,500 for future reclamation expenses as a result of earned interest.

         During  the year  ended May 31,  1998,  property  plant  and  equipment
increased  by   $13,409,400.   This  increase  was  primarily  as  a  result  of
reconsolidating  SGMC  of  $12,499,000,  development  of  mining  properties  of
$1,125,000 and the acquisition of equipment of $1,947,200. The majority of these
development  and  equipment  purchase  expenses  benefitted  the  GMMV  and SGMC
properties.  There were also capital expenditures made to keep the mill facility
owned by Plateau in standby status.

         Notes receivable from employees decreased by $393,300 as USE's chairman
retired  $431,900 of obligations to USE and Crested.  See "Voting and Management
Information - Directors and Executive  Officers of USE - Executive  Compensation
Plans and Employment  Agreements."  Notes receivable other decreased by $336,800
primarily as a result of Silva Production A.B. paying its second  installment of
$333,333  plus  interest  on the note due USE for the  purchase  of The  Brunton
Company in fiscal 1996.  Deposits and other increased by $387,600 primarily as a
result of 67,000  shares of  Company  common  stock  being  issued to  executive
officers of USE under the 1996 Stock Award Program.  Such shares are retained by
USE until the executive retires and are forfeitable under certain conditions.

Capital Resources

         General:  The primary source of USE's capital resources for fiscal 1999
will be cash on hand at May 31, 1998, equity financing for affiliated companies,
and the expected final resolution of the SMP arbitration.  Additionally, USE and
Crested will continue to offer for sale various non-core assets such as lots and
homes in Ticaboo, real estate holdings in Wyoming, Colorado and Utah and mineral
interests.  Interest,  rentals of real estate  holdings and equipment,  aircraft
chartering and aviation fuel sales also will provide cash.

         Line of Credit: USE and Crested have a $1,000,000 line of credit with a
commercial  bank. The line of credit is secured by various real estate  holdings
and equipment belonging to USE and Crested. This facility

                                       56

<PAGE>



is currently available to USE. It is anticipated that this line of credit may be
used to finance  working  capital  needs as well as the  purchase  of uranium to
deliver against a SMP delivery  contract that USE and Crested recently  received
as a partial settlement of certain SMP arbitration matters.

         Financing:  Equity  financing for SGMC and Plateau are dependant on the
market  price of gold and uranium,  among other  things.  At May 31,  1998,  the
prices  for these  metals  were  depressed  and it is not  known  when they will
recover, if at all. Management of USE and Crested believe,  based on independent
projections,  that the market  prices for these metals will improve in the short
term. No assurance can be given that the prices will improve during fiscal 1999.
If the prices do not  improve,  the ability of USE and  Crested to raise  equity
financing for these subsidiaries will be impaired.

         USE believes  that cash on hand,  in addition to its line of credit and
cash projected to be received from  operations  will be adequate to fund working
capital requirements  through fiscal 1999. However,  these capital resources may
not be sufficient  to provide the funding for major capital  expansions of USE's
mineral  properties  and,  accordingly,  USE's  development  plans may be either
temporarily or permanently  impacted.  Net cash provided by financing activities
for the year  ended May 31,  1998 of  $4,922,300  was  primarily  the  result of
issuances of USE's common stock.

Capital Requirements

         General:  The primary  requirements  for USE's working  capital  during
fiscal 1999 are expected to be the costs associated with development  activities
of Plateau, care and maintenance costs of the former SMP properties, payments of
holding fees for mining claims,  purchase of uranium for delivery to the utility
contract that was  distributed  to USE and Crested as a result of the settlement
agreement  reached  regarding  the SMP  arbitration,  USE's portion of the costs
associated  with the GMMV  properties and corporate  general and  administrative
expenses.

         SGMC:  Effective  April 7, 1998, USE purchased  889,900 Special Warrant
Units from certain Canadian investors (the "Canadian Funds") in an arm's length,
bargained  transaction between unrelated entities.  As consideration,  the Units
were  purchased  with 488,895  shares of USE's  common  stock.  The  transaction
resulted in USE increasing its ownership to 59% of the outstanding  common stock
of SGMC as of May 31, 1998 from 39% at May 31, 1997.

         Due primarily to the sustained  decline in gold prices,  USE recorded a
$1,500,000 impairment on its investment in SGMC. If financing is not obtained in
fiscal 1999 and/or gold prices  further  decline from present  levels,  USE will
reevaluate  the need for an  additional  impairment  on its  investment in SGMC,
which includes the Stock Purchase Warrant that is contingent on SGMC identifying
ounces of gold in excess of  300,000  ounces.  USE  acknowledges  that it may be
required to record a significant  impairment under Generally Accepted Accounting
Principles should financing not be obtained by SGMC to develop the project or if
gold prices decline further.

         SGMC's properties contain reserves of gold.  Preliminary  estimates are
that a 500 ton per day ("tpd")  mine/mill  operation  using a  cyanide-flotation
process, will require up to $15,000,000 to place the proposed mine and mill into
full  operation.  It is USE's  intent to complete  the  necessary  financing  to
develop the reserves of SGMC.  Management  believes that if adequate  funding is
obtained,  production will begin in fiscal 2000. SGMC is currently attempting to
negotiate  financing  with an  investment  firm  with a  proposed  plan  for the
necessary financing intended to be completed in fiscal 1999.  Sufficient capital
resources are available to SGMC to continue its permitting  and capital  raising
activities.

         SMP:  As part of a  settlement  agreement  reached  during  the  fourth
quarter  of  fiscal  1998  regarding  the SMP  Arbitration,  the SMP  mines  and
associated properties were transferred to USE and Crested. All past

                                       57

<PAGE>



holding  costs of the SMP mines were resolved and the future costs of standby as
well as  reclamation  are the  obligation  of USE and  Crested.  These costs are
estimated at approximately $85,000 per month. There are no current plans to mine
the SMP Crooks Gap properties during fiscal 1999. However,  USE and Crested will
continue to preserve the mineral  properties and develop concepts to reduce care
and maintenance costs.

         All matters in the SMP arbitration have been settled with the exception
of two issues that are currently before the 10th Circuit Court of Appeals;  oral
arguments  were had on these issues on September  24,  1998.  Management  of USE
cannot predict the timing or ultimate  outcome of this hearing but believes that
the issues will be resolved  during  fiscal 1999 unless  Nukem and CRIC elect to
appeal the decision further to the U.S.
Supreme Court and that court decides to hear the appeal.

         GMMV: On June 23, 1997, USE and USECC signed an  Acquisition  Agreement
with  Kennecott  for the right to acquire  Kennecott's  interest in the GMMV for
$15,000,000  and other  consideration.  As discussed in Note F to the  financial
statements, Kennecott paid USE $4 million upon execution of the Agreement, which
became  nonrefundable  upon the satisfaction of certain terms. The $4 million is
classified  as a  deferred  purchase  option  since  it  will be  recorded  as a
reduction of USE's purchase price if the Acquisition Agreement closes.

         During July 1998, the GMMV Management  Committee  unanimously agreed to
place the  Jackpot  Mine and  Sweetwater  Mill on active  standby  status.  This
decision was made as a result of uncertainties in the short term uranium market.
These same  uncertainties  made the financing of the  acquisition of Kennecott's
interest in GMMV more difficult.

         The standby costs of the GMMV mine,  associated  property and mill will
eventually become the responsibility of the individual  partners on a percentage
ownership  basis.  The  partners  in the GMMV are  currently  discussing  how to
operate  and  fund  the  operations  of the  properties.  Budgets  have not been
finalized,  but it is projected  the annual  holding  costs of the mine and mill
will be approximately $2,000,000. USE and Crested will be obligated to pay their
share (50%) of these costs once the  obligations  of  Kennecott  are  completely
satisfied.  Due to the  unpredictability of the uranium market, USE is unable to
predict when the GMMV properties will again be put on an active basis or when or
if it will be able to purchase Kennecott's interest in the GMMV.

         Plateau:  Plateau  owns  and  operates  the  Ticaboo  townsite,  motel,
convenience store and restaurant.  The operations resulted in fiscal 1998 losses
of $800,000,  which were  absorbed by USE.  USE  continues to work on methods of
increasing revenues and reducing costs. There has been an annual growth in sales
since USE has owned  Plateau.  USE has  constructed a total of seven homes which
are held for sale.  During fiscal 1998,  the homes were written down by $100,000
to the appraised value.

         USE is currently  working to obtain the necessary  permits from the NRC
and State of Utah to place the  Shootaring  mill which is owned by  Plateau  and
located  in  southern  Utah  into  production.  USE is  seeking  debt or  equity
financing of between  $6,000,000  to $9,000,000 to put the mill and Tony M. Mine
into  production.  Until such time as the  financing is obtained and  profitable
contracts are obtained, USE will not put the properties into production.

         Yellow Stone Fuels Corp. ("YSFC"): YSFC has sufficient cash to complete
its fiscal 1999 exploration  program on its in-situ uranium  properties.  At May
31, 1998,  YSFC owed USE and Crested  $400,000 on a convertible  promissory note
plus $40,000 in interest for a total of $440,000. The note bears interest at 10%
per annum and is due in December  1998. At May 31, 1998,  YSFC also owed USE and
Crested  $161,700 for  miscellaneous  payroll and operating  expenses.  YSFC has
indicated its desire to pay the  indebtedness in cash but it is not certain that
a cash payment will occur as YSFC may elect at its option to pay the  promissory
note with shares of its common stock.

         Term  Debt and  Other  Obligations:  Debt at May 31,  1998 of  $503,900
constitutes a relatively  low  percentage of  capitalization  given the value of
assets owned by USE and the various  activities it participates  in. The debt is
primarily  for property and  equipment  purchased by USECC,  Sutter and FNG. The
debt bears  different  interest rates and is due under various payment terms. It
is  anticipated  that all debt  payments  will be able to be made in the  normal
course of USE's business.

         Reclamation  Obligations:  It is not  anticipated  that  any  of  USE's
working  capital will be used in fiscal 1999 for the  reclamation  of any of its
mineral  properties.  The reclamation  costs are long term and are either bonded
through  the use of cash bonds or the pledge of  assets.  It is not  anticipated
that any of USE's mining  properties will enter the  reclamation  phase prior to
May 31, 1999.

         Prior  to  fiscal  1996,  USE  and  Crested   assumed  the  reclamation
obligations,  environmental  liabilities and contingent liabilities for employee
injuries, from mining the Crooks Gap and other properties in the Sheep and Green
Mountain  Mining  Districts  as well as the  SGMC  properties.  The  reclamation
obligations,  which are established by government  agencies,  were most recently
set at $1,451,800 for the SMP properties and $27,000 on the SGMC properties. The
amount of accruals for environmental liabilities for each site are determined by
estimating costs associated with current or expected reclamation and remediation
plans.  These plans include  detailed  descriptions of the work to be performed,
and in many cases  involve  the work of third party  consultants.  The plans are
submitted  annually  to  government  agencies  who review  them and set the bond
amounts.

         To assure the reclamation work will be performed,  regulatory  agencies
require  posting of a bond or other  security.  USE and Crested  satisfied  this
requirement  with respect to SMP properties by mortgaging their executive office
building in Riverton, Wyoming.

         Reclamation  obligations  on the  GMMV  Big  Eagle  properties  and the
Sweetwater Mill,  estimated at approximately  $23,620,000,  have been assumed by
the  GMMV  venturers,  and  secured  by a bank  letter  of  credit  provided  by
Kennecott.   The  reclamation  and  environmental   costs  associated  with  the
Sweetwater  Mill will not commence  prior to conclusion of mining  activities on
Green  Mountain  except  for the open pit mine  near the  Mill.  As  uranium  is
processed through the Mill, a reclamation  reserve will be funded on the unit of
production basis. Up to $8,000,000 (in 1990 dollars) in any reclamation costs on
the  Sweetwater  mill and associated  properties  which may be incurred prior to
commencement  of  production  or 2001 will be loaned by UNOCAL to the GMMV to be
repaid only out of production.

         Reclamation  obligations  of Plateau are covered by a  $7,270,400  cash
bond at May 31, 1998 to the U.S. Nuclear Regulatory  Commission and a $1,561,600
cash  deposit as of May 31,  1998 for the  resolution  of any  environmental  or
nuclear claims.

         Other:  Although USE and Crested currently are not in production on any
mineral  properties,  development  work  continues  on  several  of their  major
investments.  USE and  Crested  are not  using  hazardous  substances  or  known
pollutants  to any great  degree in these  activities.  Consequently,  recurring
costs for managing hazardous substances, and capital expenditures for monitoring
hazardous substances or pollutants have not been significant.  Likewise, USE and
Crested  do not have  properties  which  require  current  remediation.  USE and
Crested are also not aware of any claims for personal injury or property damages
that need to be accrued or funded.

         The tax years  through May 31, 1992 are closed  after audit by the IRS.
USE  currently  has filed a  request  for an appeal  hearing  on an IRS  agent's
findings for the years ended May 31, 1993 and 1994.  Although all indicators are
that  the  findings  of the IRS  audit  for 1993 and  1994  will not  result  in
additional  tax, the  findings of the audit could  affect the tax net  operating
loss of USE.  Management  of USE  feels  confident  that  it will  prevail  on a
majority of the issues. No assurance of the outcome of the appeal can be

                                       59

given.  The tax  years  ended  May 31,  1995 and 1996 are also  currently  being
audited by the IRS. No determination on these audits can be made as they are not
yet completed.

Results of Operations

Fiscal 1998 Compared to Fiscal 1997

         Operations  resulted  in a net after tax loss of  $983,200 or $0.15 per
share as compared to a net after tax loss of $3,724,500 or $0.58 per share.  The
primary cause of this  reduction in USE's loss during fiscal 1998 were increased
revenues of $5,768,300  while costs and expenses only  increased by  $1,697,300.
Net cash used in  operating  activities  decreased  to  $2,245,000  in 1998 from
$2,647,600 in 1997 primarily due to the decrease in loss from operations  offset
by other working capital changes.

         Revenues:  Mineral revenues  increased by $862,400 as the result of USE
receiving  its  proportionate  share of the net  proceeds  from the  delivery of
pounds of uranium under an SMP contract.  This was the last delivery  under this
contract and no similar delivery proceeds were received during fiscal 1997.

         Commercial operations revenue increased by $1,304,100 as a result of an
increase of $1,019,100 pertaining to increased equipment rentals to the GMMV and
the development of mining properties.  Additionally, revenues generated at USE's
Ticaboo   townsite   increased  by  $285,000  in  fiscal  1998.  SMP  litigation
settlements  are recorded net of any  accounts  receivable  from SMP for holding
costs of the mining properties. During fiscal 1998, such revenues increased by a
net of $3,586,200 to $4,590,000.

         Construction  contract revenues  decreased by $1,038,600 as a result of
USE's  subsidiary  Four Nines Gold,  Inc.("FNG")  not obtaining  any  commercial
construction  contracts.  FNG's  equipment and employees  were used  exclusively
during  fiscal  1998 on the  construction  of  various  roads,  ponds  and other
excavation  projects  for the GMMV.  Revenues  from  Management  fees  increased
significantly due to the work that was done under the GMMV agreements that allow
USE to receive a 10% management fee on all billable  charges under the 1990 GMMV
agreement.

         Costs  and  Expenses:   Mineral  operation  expenses  and  General  and
administrative  expenses increased by $821,700 and $2,029,900,  respectively due
to  increased  operations  at USE's  GMMV and  Plateau  mineral  and  commercial
operations,  and increased  salary  expense.  USE recognized a mineral  interest
impairment of $1,500,000  pertaining  to SGMC as discussed  above.  There was no
impairment of mineral  properties taken during fiscal 1997. There was however an
abandonment of mining claims in 1997  pertaining to certain mining claims in the
amount of $1,225,800. No abandonments of mining claims occurred in fiscal 1998.

         Construction  costs decreased by $716,200 due to FNG not performing any
commercial  construction  work, and provision for doubtful accounts decreased by
$614,200 as no additional provision was required.

Fiscal 1997 Compared to Fiscal 1996

         Revenues for the twelve months ended May 31, 1997 totaled $5,790,200 as
compared to revenues at May 31, 1996 of $9,632,200. This decrease in revenues of
$3,842,000 is primarily the result of no revenues being  recognized from mineral
sales in fiscal 1997  (decrease of  $3,116,700).  During the prior year, USE and
Crested made certain  deliveries  of U3O8 for SMP.  Other  decreases in revenues
were oil sales, $45,500;  sales of assets,  $312,800;  and construction revenues
from USE's subsidiary FNG,  $2,755,900.  These decreases in revenues were offset
by increased  commercial  sales,  $780,300;  advance royalties from Cyprus Amax,
$207,300;   partial  distribution  of  SMP  funds,  $1,003,800;   and  increased
management fees and other revenues, $323,600.

<PAGE>



         With the  exception of cost of minerals  sold,  construction  costs and
commercial operations,  costs and expenses remained the same as they had been in
1996.  Cost of minerals  sold  declined by $2,766,700 as a result of Crested and
USE not  delivering  any  U3O8  under  the SMP  contracts  during  fiscal  1997.
Construction  costs  declined by $2,325,200 as a result of USE's  subsidiary FNG
not being able to secure  construction  contracts.  Currently,  FNG is using its
equipment and employees on the  construction  of earth  structures and roads for
the GMMV. It is not known if FNG will be able to obtain contracts in the future.
During fiscal 1997,  USE also  recognized a provision  for doubtful  accounts of
$614,200. This is as a result of a third party defaulting on a sale of land that
USE and Crested sold during a prior period.  USE also  recognized an increase in
the  abandonment of mineral leases of $897,100.  The total expense of $1,225,800
for mineral property  abandonment was the result of Crested abandoning a mineral
property  having a book value of $71,500 and SGMC  abandoning  properties with a
book value of $1,154,300.

         General and administrative expenses increased only slightly by $238,600
due to expansion of operations. Increases in general and administrative expenses
were reduced by overhead and direct charges to GMMV, SMP and SGMC.

         Equity  losses  recognized  by USE  increased by  $272,300.  Operations
resulted in a net loss of $3,724,500 or $0.58 per share in 1997 as compared to a
net profit of $270,700 or $0.04 per share in 1996.

Future Operations:

          USE has generated  losses in two of the last three years,  as a result
of holding costs and  permitting  activities  in the mineral  segment along with
impairments of mining claims and investments in  subsidiaries  that are involved
in the minerals business and from certain commercial  operations.  USE is in the
process of developing and/or holding  investments in gold and uranium properties
that are  currently not  generating  any operating  revenues.  These  properties
require  expenditures  for  items  such as  permitting,  development,  care  and
maintenance,  holding  fees,  corporate  overhead and  administrative  expenses.
Success in the  minerals  industry is  dependant on the price that a company can
receive for the minerals  produced.  USE cannot predict what the long term price
for gold and uranium will be and therefore  cannot predict when, or if, USE will
generate net income from operations.

         In  addition,   legal  expenses  associated  with  the  litigation  and
arbitration  surrounding the SMP Partnership and the inability of USE to utilize
all the funds that have been awarded to USE and Crested by the Arbitration Panel
and confirmed by the Federal Court have compounded USE's operating and cash flow
position in the past.  USE believes  that the SMP  arbitration  will be resolved
during  fiscal 1999.  USE believes that it will meet its  obligations  in fiscal
1999 as well as be able to secure  financing to further the  development  of its
mineral properties and place them into production.

Effects of Changes in Prices

         Mining operations and the acquisition,  development and sale of mineral
properties are significantly  affected by changes in commodity prices. As prices
for a particular  mineral  increase,  prices for prospects for that mineral also
increase, making acquisitions of such properties costly, and sales advantageous.
Conversely,  a price decline facilitates  acquisitions of properties  containing
that mineral,  but makes sales of such properties  more  difficult.  Operational
impacts  of  changes  in  mineral  commodity  prices  are  common in the  mining
industry.

         Uranium and Gold.  Changes in the prices of uranium and gold affect USE
to the greatest extent. When uranium prices were relatively high in fiscal 1988,
USE and Crested  acquired  the Crooks Gap  properties,  and  thereafter  put the
properties  into  production.  When uranium  prices fell sharply  during  fiscal
1989-1991,  USECC suspended the mining  operations of SMP, because uranium could
be purchased at prices

                                       61

<PAGE>



less than the costs of  producing  uranium.  Uranium  production  in the  United
States reportedly fell by 25 to 33 percent in 1990, due to the lowest prices for
uranium  since the  market  developed  in the 1960s.  However,  these low prices
created  opportunities  for  the  acquisition  of the  Sweetwater  Mill  and the
Shootaring Mill.

         Changes in uranium prices directly affect the  profitability of uranium
supply agreements with utilities.  Fixed-price  agreements  become  advantageous
when the spot market price for uranium falls significantly below the price which
a utility has agreed to pay.

         Several of the original SMP utility contracts have been completed,  and
the rest assigned out to the partners in connection with the partial  settlement
of litigation with Nukem/CRIC. For fiscal 1999, USE and Crested have one utility
supply contract, which is market related. One purchase contract, which is market
related has been sold to Nukem  subsequent  to May 31, 1998 for $35,000 for each
year if Nukem  purchases  uranium  from the third  party;  if Nukem  doesn't  so
purchase,  no payment  would be made to USE and Crested . However,  the purchase
contract  requires six months  notice to the  supplier  before  delivery,  which
notice  fixes the price.  a price  decline  between  notice and  delivery  could
adversely  impact USE and Crested.  Additional  contracts with utilities will be
sought as the uranium properties of USE and Crested go into production.

         USE believes  SGMC's  Lincoln Mine will be profitable  with gold prices
over $290 per ounce.  The price of gold was  adversely  impacted  in October and
November 1997 and prices in January 1999 were approximately $290 per ounce.

         Molybdenum  and Oil.  Changes in prices of molybdenum and petroleum are
not  expected to  materially  affect USE with  respect to either its  molybdenum
advance royalties or its fees associated with oil production.  a significant and
sustained   increase  in  demand  for  molybdenum  would  be  required  for  the
development  Mt.  Emmons  properties  by Cyprus Amax since Cyprus Amax has other
producing mines.

                             INFORMATION ABOUT YSFC

         Yellow  Stone  Fuels  Corp.,  was  organized  on  February  17, 1997 in
Ontario,  Canada.  As of February 17, 1997,  YSFC  acquired all the  outstanding
shares of Common Stock of Yellow Stone Fuels, Inc. (a Wyoming  corporation which
was organized on June  3,1996),  in exchange for YSFC issuing the same number of
shares of YSFC Stock to the former  shareholders  of Yellow  Stone  Fuels,  Inc.
("YFI").  YSFC and its  wholly-owned  subsidiary  Yellow Stone  Fuels,  Inc. are
herein collectively referred to as YSFC.

         In order to concentrate  the efforts of USECC on  conventional  uranium
mining  using the  Shootaring  and  Sweetwater  Mills,  USECC  decided to take a
minority  position in Yellow Stone Fuels,  Inc. and not be directly  involved in
properties  believed  suitable for the production of uranium through the in-situ
leach ("ISL")  mining  process.  USECC will have the right of first refusal with
respect  to any  uranium  ore  bodies  YSFC  discovers  which  are  amenable  to
conventional  mining and milling  and YSFC will have the right of first  refusal
with respect to ore bodies  discovered by USECC amenable to the ISL process.  In
the ISL process,  groundwater  fortified with oxidizing  agents is pumped in the
ore body, causing the uranium contained into the ore to dissolve.  The resulting
solution is pumped to the surface where it is further  processed to a dried form
of  uranium  which is  shipped  to  conversion  facilities  for  eventual  sale.
Generally,  the ISL process is more cost  effective and  environmentally  benign
compared to conventional  underground mining techniques.  In addition, less time
may be required to bring an ISL mine into  operation  than to permit and build a
conventional mine.

         In Wyoming,  YSFC has staked and/or holds 243 unpatented  mining claims
and has entered into four State leases  covering a total of 8,700 acres  located
in the Powder River Basin and Red Desert uranium  districts.  Three State leases
have a 10 year term expiring October 1, 2006; one State lease has a 10 year term
expiring  June 1, 2008;  each require  annual  rental of $1.00 per acre for five
years, then $2.00 for the second

                                       62

<PAGE>



five years,  or sooner upon the discovery of commercial  quantities of minerals;
plus a 5% gross  royalty  of the value of  uranium  bearing  ore mined  from the
leased properties is payable to the State of Wyoming.

         In  New  Mexico,  YSFC  has  staked  and  holds  39  unpatented  mining
claims(approximately 780 acres) in the Grants uranium region of New Mexico.

         Material Contracts Between YSFC, USE and Crested.  In fiscal 1997, USE,
USECC and the GMMV entered into several  agreements with YSFC. One contract is a
Milling Agreement through Plateau Resources;  the Shootaring Canyon mill will be
available to YSFC to transport  uranium  concentrate  slurry and loaded resin to
the mill and  process  it into  uranium  concentrate  ("yellowcake"),  for which
Plateau will be paid its direct costs plus 10%. Other contracts  include a Drill
Rig Lease  Agreement  for YSFC to access  USE  drilling  rigs at the  prevailing
market rates;  an  Outsourcing  and Lease  Agreement for  assistance  from USECC
accounting  and technical  personnel on a cost plus 10% basis and a sublease for
1,000 square feet of office space and USE of various office equipment for $2,000
per month; and a Ratification of Understanding by which USECC will offer to YSFC
(with a  reserved  royalty  in  amounts  to be  agreed  on  later)  any  uranium
properties  amenable to in-situ production which USECC acquires or has the right
to  acquire.  In return,  YSFC will  offer to USECC ( with a reserve  royalty in
amounts  to be agreed on later)  uranium  properties  amenable  to  conventional
mining methods which YSFC acquires or has the right to acquire.  USECC also will
make its library of geological  information and related  materials  available to
YSFC.  YSFC also has a Storage  Agreement  with GMMV by which YSFC  stores  used
low-level contaminated mining equipment at the Sweetwater Mill.

         In fiscal  1998,  YSFC  sold  1,219,000  shares  of Common  Stock to 94
investors in a private placement,  at $2.00 per share; net proceeds to YSFC were
$2,041,060  after  payment of $316,940 in  commissions  to the  placement  agent
(AFFC, Denver,  Colorado) and $80,000 in legal and accounting expenses.  Most of
these investors were "accredited"  investors.  The securities were sold pursuant
to Rule 506 of Regulation D under the Securities Act of 1933, and are restricted
from  resale  under Rule 144.  In  connection  with the  private  placement,  in
September  1997,  USE entered into an Exchange  Rights  Agreement  with YSFC and
AFFC, pursuant to which this Exchange Offer is made.

         YSFC has  11,714,000  shares of Common  Stock  issued and  outstanding,
including  3,000,000  shares  (25.6%)  issued to USE and  Crested.  YSFC has 128
shareholders. Most of the funds used by YSFC have been provided by USECC under a
$400,000  loan  facility.  For more  information  on this item,  see "Voting and
Management  Information - Certain  Relationships  and Related  Transactions." As
part  consideration  for the loan,  USE and Crested  entered into a Voting Trust
Agreement having an initial term of 24 months with two principal shareholders of
YSFC,  whereby USE and Crested would have voting control of more than 50% of the
outstanding  shares of YSFC if YSFC  does not  repay  the  loan.  If the loan is
repaid, the Voting Trust Agreement is terminated.

         In  addition  to  advances  under  the loan  facility,  USECC  has paid
$117,800 (through November 30, 1998) of expenses incurred by YSFC; these amounts
are owed t USECC by YSFC.

                    YSFC MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Liquidity and Capital Resources at November 30, 1998

         During  the  six  months  ended  November  30,  1998,   cash  and  cash
equivalents  decreased by $308,100 to $1,410,300  from  $1,718,499 as of May 31,
1998.  This decrease in cash came as a result of $100,500 cash being consumed in
the  development  of mining  properties,  a $10,900  net  reduction  of  various
accounts payable

                                       63

<PAGE>



and  $163,600  being used in  operations.  Although  the cash  position  of YSFC
decreased, the working capital of YSFC remained at $832,500.

         YSFC has current long term debt of $400,000  with  accrued  interest of
approximately  $60,000.  This debt is payable at YSFC's  option to its affiliate
USE and its subsidiary  Crested by paying either cash or common stock of YSFC on
or before  December  31,  1998.  It was not known at November  30, 1998 how YSFC
would elect to repay the debt. In addition to this indebtedness YSFC is indebted
to the USECC Joint  Venture,  ("USECC")  in the amount of $117,800  for expenses
that have been paid by USECC.

         The source of capital that YSFC will draw upon to retire debt to USECC,
USE and Crested  will be the USE of cash on hand.  YSFC  continues to search for
joint venture  partners to assist in the development of its mineral  properties.
No  assurance  can be given that such  ventures can be  established  and funded.
YSFC's mineral  properties consist of uranium mineral claims. As of November 30,
1998 the price of uranium  was  depressed.  It is not known when the spot market
price will increase to the point where funding for operations can be obtained to
put the properties into production.

Results of Operations

Three Months Ended November 30, 1998
Compared to Three Months Ended November 30, 1997

         During the six months ended November 30, 1998, YSFC recognized  $40,700
of interest revenues from cash held in interest bearing accounts. During the six
months ended November 30, 1997, YSFC recognized $6,400 of interest revenues. The
increased  revenues  during the six months ended November 30, 1998 resulted from
larger cash balances for longer periods of time during the current period.

         Costs and expenses  remained  relative  constant as YSFC  continued its
exploration and development programs.

         Due to the increased  revenues  recognized  during the six months ended
November 30, 1998,  YSFC's net loss decreased from $222,200 at November 30, 1997
to $163,600 at November 30,1998.

Liquidity and Capital Resources at May 31, 1998

         During the year ended May 31, 1998 YSFC issued  1,219,000 shares of its
common stock and received  $2,121,100 net from the issuance of this stock.  Cash
was  used  in  operations  and  investing   activities   $315,000  and  $118,000
respectively. The cash consumed in investing operations was used in the purchase
of mineral properties, $52,500 and property and equipment, $65,500.

         The  increase  in  working  capital as a result of  increased  cash was
offset by an increase  in  accounts  payable to  affiliates,  $201,600,  and the
current portion of notes receivable,  $397,500. The increase in accounts payable
to  affiliates  was as a result of various  expenses  being paid by USECC  Joint
Venture  and  billed to YSFC.  These  expenses  relate to payroll  expenses  and
miscellaneous  accounts  payable.  At May 31, 1998 the note payable to USECC was
classified  as current as it is due on or before  December 31, 1998.  At May 31,
1997 the note payable to USECC was classified as long term.

         Sources of capital  during the year ended May 31, 1999 will be provided
by cash on hand,  interest earned on the cash investments and the potential sale
of mineral properties to joint venture properties.

         Requirements  for YSFC's  capital  resources  are on going  General and
Administrative expenses,  continued exploration of YSFC's mineral properties and
the location of new properties and  businesses.  The long term debt due USECC in
the amount of $400,000 bears interest at 10% per annum and comes due on

                                       64

December  31,  1998.  YSFC may elect at its  option to pay the  indebtedness  in
either cash or its common stock.  The  retirement of this debt therefore may not
require the USE of any of YSFC's capital resources should the debt be retired by
the issuance of common  stock.  YSFC also plans a limited  exploration  drilling
program on its mineral properties.

         It is anticipated  that YSFC will be able to satisfy all of its capital
commitments  with the cash it had on hand at May 31,  1998.  Management  of YSFC
continues to pursue new business opportunities as well as joint venture partners
on the exploration and development of its mineral properties.

Results of Operations

Fiscal 1998 Compared to Fiscal 1997

         Revenues for the year ended May 31, 1998 were $49,300 as compared to no
revenues  being  recognized  during the year ended May 31, 1997. The increase in
revenues was as a result of the  investment of funds  received from the issuance
of YSFC's common stock.

         During the year  ended May 31,  1998 costs and  expenses  increased  by
$200,000.  This increase was in general and administrative expenses and interest
expense  of  $165,100  and  $40,300  respectively.  General  and  administrative
expenses  increased as a result of additional  employees  being hired to explore
and develop  existing mineral  properties and locate new ones.  Interest expense
increased as a result of the  borrowing  from USECC in the amount of $400,000 at
10% interest per annum.

         Due to the  lack of  revenues  during  the  year  ended  May 31,  1998,
operations resulted in a loss of $546,000.  The increase in the loss of $150,700
over the loss experienced  during the year ended May 31, 1997 of $395,300 was as
a result of increased operations.

Executive Compensation

         USE. Under a Management Agreement dated August 1, 1981, USE and Crested
share certain general and administrative expenses, including compensation of the
officers and directors of the companies  (but excluding  directors'  fees) which
have been paid through the USECC Joint Venture ("USECC").  Substantially all the
work  efforts of the  officers of USE and Crested are devoted to the business of
both companies.

         All USECC  personnel are USE employees,  in order to utilize USE's ESOP
as an employee benefit mechanism.  USE charges USECC for the direct and indirect
costs of its  employees  for time  spent on USECC  matters,  and  USECC  charges
one-half of that amount to each of Crested and USE.

         The following table sets forth the  compensation  paid to the USE Chief
Executive  Officer,  and those of the four most highly compensated USE executive
officers who were paid more than  $100,000 cash in any of the three fiscal years
ended May 31, 1998. The table includes compensation paid such persons by Crested

Executive Compensation Plans and Employment Agreements

         To  provide  an  incentive  to Mr.  Larsen to  develop  the GMMV into a
producing  operation  as soon as  possible,  in  fiscal  1993  the USE  Board of
Directors adopted a long-term  incentive  arrangement under which Mr. Larsen was
to be paid a  non-recurring  $1,000,000  cash  bonus,  provided  that the Nuexco
Exchange Value of uranium oxide concentrates were maintained at $25.00 per pound
for  six  consecutive  months,  and  provided  further  that  USE  had  received
cumulative cash  distributions of at least  $10,000,000 from GMMV as a producing
property.  In December,  1997, Mr. Larsen agreed to relinquish all of his rights
under this bonus arrangement related to GMMV.

         In December  1997,  USE paid Mr.  Larsen a bonus of $732,000  ($615,000
after  taxes)  in  recognition  of his  service  to USE and  work  in  acquiring
Kennecott  as a joint  venture  partner in 1990 for  $15,000,000  in cash plus a
$50,000,000  commitment to USECC to develop the Green Mountain  properties;  the
negotiations  of Mr.  Larsen  in  acquiring  Plateau  Resources  Ltd.  with  the
Shootaring Mill (in fiscal 1994) and the most recent  negotiations  for USECC to
enter  into the  Acquisition  Agreement  (fiscal  1998) to  acquire  Kennecott's
interest in the GMMV  resulting in the purchase  option payment of $4,000,000 to
USE and Crested.  The bonus was  recommended  by USE's  Compensation  Committee,
taking  into  account  pay  levels  at  comparable  corporations  in the  mining
industry, and was approved by the Board of Directors.  USE and Mr. Larsen agreed
that the bonus is further in full  settlement  of the bonus to Mr.  Larsen which
was  authorized  (but never paid) by the Board of Directors  in 1993,  which had
been   conditioned  on  the  spot  price  of  uranium   concentrates   and  cash
distributions from the GMMV to USE.

         USE has adopted a plan to pay the estates of Messrs.  Larsen, Evans and
Svilar  amounts  equivalent  to the salaries  they are  receiving at the time of
their death, for a period of one year after death, and reduced amounts for up to
five years thereafter.  The amounts to be paid in such subsequent years have not
yet been established, but would be established by the Boards of USE and Crested.

         Mr.  Svilar has an  employment  agreement  with USE and Crested,  which
provides for an annual salary in excess of $100,000, with the condition that Mr.
Svilar pay an  unspecified  amount of expenses  incurred by him on behalf of USE
and its  affiliates.  In the  event Mr.  Svilar's  employment  is  involuntarily
terminated,  he is to receive an amount equal to the salary he was being paid at
termination,  for a two year  period.  If he should  voluntarily  terminate  his
employment, USE and Crested will pay him that salary for nine months thereafter.
The foregoing is in addition to Mr. Svilar's Executive Severance and Non-Compete
Agreement with USE (see below).

         In  fiscal  1992,  USE  signed  Executive   Severance  and  Non-Compete
Agreements with Messrs. Larsen, Evans, Svilar and Lorimer, providing for payment
to such person upon  termination of his employment  with USE,  occurring  within
three  years  after a  change  in  control  of USE,  of an  amount  equal to (i)
severance pay in an amount equal to three times the average annual  compensation
over the prior five taxable years ending  before  change in control,  (ii) legal
fees and expenses incurred by such persons as a result of termination, and (iii)
the difference between market value of securities issuable on exercise of vested
options to purchase  securities in USE, and the options'  exercise price.  These
Agreements  also provide  that for the three years  following  termination,  the
terminated  individual  will not compete with USE in most of the western  United
States in  regards  to  exploration  and  development  activities  for  uranium,
molybdenum,  silver or gold. For such non-compete covenant,  such person will be
paid  monthly  over a three year  period an agreed  amount for the value of such
covenants.  These  Agreements  are intended to benefit  USE's  shareholders,  by
enabling such persons to negotiate  with a hostile  takeover  offeror and assist
the Board  concerning  the fairness of a takeover,  without the  distraction  of
possible  tenure  insecurity  following  a change in  control.  As of this Proxy
Statement date, USE is unaware of any proposed hostile takeover.

         In June 1998, USE and Crested paid cash bonuses totaling  $325,000 (net
after taxes) to four officers for their extraordinary  efforts since 1992 in the
litigation  and  arbitration  proceedings  with  Nukem,  Inc. As of the date the
bonuses  were paid,  these  efforts had  resulted  in USE and Crested  receiving
approximately $8,000,000 from Nukem and CRIC, net of the legal and related costs
incurred by USE. These bonuses were recommended by the Compensation Committee of
the Board of Directors  in the  following  amounts:  $50,000 for John L. Larsen,
$25,000 for Keith G. Larsen, and $125,000 each for Daniel P. Svilar and R. Scott
Lorimer.  In February  1999,  USE issued  50,000  restricted  shares each to Mr.
Svilar and Mr.  Lorimer for their success in getting the final $6 million of the
Nukem judgment paid.

         Employee Stock  Ownership  Plan  ("ESOP").  An ESOP has been adopted to
encourage ownership of the Common Stock by employees, and to provide a source of
retirement  income to them. The ESOP is a combination stock bonus plan and money
purchase  pension  plan.  It is expected  that the ESOP will  continue to invest
primarily in the Common Stock. Messrs. Larsen, Herron and Evans are the trustees
of the ESOP.

         Contributions  to  the  stock  bonus  plan  portion  of  the  ESOP  are
discretionary  and are  limited  to a maximum of 15% of the  covered  employees'
compensation  for each year ended May 31.  Contributions  to the money  purchase
portion of the ESOP are mandatory  (fixed at ten percent of the  compensation of
covered employees for each year), are not dependent upon profits or the presence
of accumulated  earnings,  and may be made in cash or shares of Company's Common
Stock.

         USE made a  contribution  of 49,470 shares to the ESOP for fiscal 1998,
all of which were contributed under the money purchase pension plan. At the time
the shares were  contributed,  the market price was $6.57 per share, for a total
contribution  with a market  value of  $324,655  (which has been funded by USE).
Crested  and USE are  each  responsible  for  one-half  of  that  amount  (i.e.,
$162,327.50)  and Crested  currently  owes its  one-half  to USE.  10,659 of the
shares were allocated to the ESOP accounts of the executive officers.

         Employee  interests  in the ESOP are  earned  pursuant  to a seven year
vesting schedule; after three years of service, the employee is vested to 20% of
the ESOP  account,  and  thereafter  at 20% per year.  Any portion  which is not
vested is forfeited upon  termination  of employment,  other than by retirement,
disability, or death.

         The  maximum  loan   outstanding   during  fiscal  1998  under  a  loan
arrangement  between USE and the ESOP was  $1,014,300  at May 31, 1998 for loans
made in fiscal 1992 and 1991.  Interest  owed by the ESOP was not booked by USE.
Crested pays one-half of the amounts contributed to the ESOP by USE. Because the
loans are  expected to be repaid by  contributions  to the ESOP,  Crested may be
considered to  indirectly  owe one-half of the loan amounts to USE. The loan was
reduced by $183,785 plus interest of  $168,574.84  through the  contribution  of
shares by the ESOP to the ESOP in 1996. There was no similar reduction, however,
for fiscal 1997 or fiscal 1998.

         Stock Option Plan.  USE has an  incentive  stock option plan  ("ISOP"),
reserving an aggregate  of  2,750,000  shares of Common Stock for issuance  upon
exercise  of options  granted  thereunder.  Awards  under the plan are made by a
committee  of two or more  persons  selected  by the  Board  (presently  Messrs.
Herron, Bebout, Brenman and Fraser) and ratified by the Board of Directors.

         Options expire no later than ten years from the date of grant, and upon
termination  of employment  for cause.  Subject to the ten year maximum  period,
upon termination, unless terminated for cause, options are exercisable for three
months or in the case of retirement, disability or death, for one year.

         For information  about options issued prior to fiscal 1998,  please see
"Note J to the USE Consolidated  Financial Statements" for fiscal year ended May
31, 1998. In fiscal 1997,  options to purchase 106,100 shares (previously issued
to employees in 1992 and 1996) were exercised. None of the exercised options had
been held by officers or directors.

                                       70

<PAGE>



         The Board of Directors  approved (on  September  25, 1998) the issuance
(to  officers,  employees,  and  non-employee  directors  and an advisory  board
member) of options to purchase  837,500  shares of USE Common Stock.  737,500 of
the options have an exercise  price of $2.00 per share (the closing stock market
price of USE  stock on  September  25,  1998 was  $1.50);  100,000  options  are
qualified  and have an  exercise  price of $2.875 per share (the  closing  stock
market price of USE stock on December 4, 1998).  The options  issued to officers
included 112,500 to John L. Larsen,  87,500 to Keith G. Larsen, 75,000 to Harold
F. Herron, 75,000 to Daniel P. Svilar, 75,000 to R. Scott Lorimer, and 50,000 to
Max T. Evans.  Outside directors Nick Bebout, H. Russell Fraser, Don C. Anderson
and David W. Brenman,  and Advisory Board Member Alan K. Simpson,  each received
an option for 12,500 shares, with the same exercise price.

         On December 4, 1998, the USE  shareholders  approved  amendments to the
Incentive  Stock Option Plan,  which increased the shares  authorized  under the
Plan up to 2,750,000 shares, and reset the Plan's term to expire 2008.

         The following table shows  unexercised  options,  how much thereof were
exercisable, and the dollar values for in-the-money options, at May 31, 1998.

         1996 Stock  Award  Program.  USE has an annual  incentive  compensation
arrangement  for the  issuance of up to 67,000  shares of Common Stock each year
(from 1997  through  2002) to executive  officers of USE, in amounts  determined
each year based on earnings of USE for the prior fiscal.

                                       72

<PAGE>



         Shares are issued  annually,  but each officer to whom shares are to be
issued must be  employed by USE as of the issue date of the grant year,  and USE
must have been  profitable  in the  preceding  fiscal year.  The  officers  will
receive up to an  aggregate  total of 67,000  shares per year for the years 1997
through 2002,  although if in prior years,  starting in 1997,  fewer than 67,000
USE shares are awarded in any year,  the  unissued  balance of the 67,000  share
maximum will be available for issue in subsequent years (through 2007). One-half
of the compensation  expense under the Program is the responsibility of Crested.
The Board of  Directors  determines  the date each  year when  shares  are to be
issued.

         Each  allocation  of shares is issued in the name of the  officer,  and
will be earned  out  (vested)  over 5 years,  at the rate of 20% as of May 31 of
each year following the date of issue.  However, none of the vested shares shall
become  available to or come under the control of the officer until  termination
of employment by retirement,  death or disability.  Upon termination,  the share
certificates  will  be  released  to  the  officer;   until   termination,   the
certificates  are held by the Treasurer of USE. Voting rights are exercised over
the  shares  by  the   non-employee   directors  of  USE;   dividends  or  other
distributions  with respect to the shares will be held by the  Treasurer for the
benefit of the officers.

         The number of shares to be awarded each year out of such 67,000  shares
aggregate limit is determined by the Compensation  Committee,  based on criteria
including USE's earnings per share for the prior fiscal year.  Other factors may
be taken into  consideration  by the  Compensation  Committee.  The total shares
issued are divided among the officers based on the following  percentages:  John
L. Larsen 29.85%, Daniel P. Svilar 22.39%, Max T. Evans 17.91%, Harold F. Herron
14.93% and R. Scott Lorimer 14.93%. USE was not profitable in fiscal 1997, so no
shares were issued for that year.  For fiscal 1998, the  Compensation  Committee
awarded  67,000 shares to the  officers.  The award was based on the revenues of
USE ($11,558,500) in fiscal 1998, and the finding by the Compensation  Committee
that but for the  $1,500,000  expense  which  resulted  from a writedown  of the
investment  in the gold  property  in  California,  USE would  have  reported  a
$515,800 profit for fiscal 1998.

         Under a previous equity incentive program,  USE and Crested have issued
stock  bonuses to various  executive  officers and  directors of USE and others.
These  shares  are  subject  to  forfeiture  to the  issuer  by the  grantee  if
employment terminates otherwise than for death, retirement or disability. If the
required  service is  completed,  the risk of  forfeiture  lapses and the shares
become the unrestricted  property of the holder.  The executive  officers,  as a
group received 97,650 shares of Common Stock through fiscal 1997.

         Subsidiary Plans. During the year ended May 31, 1991, Brunton adopted a
salary deduction plan intended to qualify as a deferred  compensation plan under
Internal Revenue Code Section 401(k).  Harold F. Herron, John L. Larsen,  Daniel
P. Svilar and R. Scott  Lorimer are the only  Company  officers  who are able to
participate in this retirement  plan. The fiscal 1994  acquisition of Brunton by
USE, and the sale of Brunton in 1996, have not affected the Brunton 401(k) plan.

         Other than as set forth above,  neither USE nor any of its subsidiaries
have any pension, stock option, bonus, share appreciation, rights or other plans
pursuant to which they  compensate the executive  officers and directors of USE.
Other than as set forth above, no executive officer received other  compensation
in any form which, with respect to any individual named in the Cash Compensation
Table,  exceeded ten percent of the compensation  reported for that person,  nor
did all executive  officers as a group receive  other  compensation  in any form
which exceeded ten percent of the compensation reported for the group.

Directors' Fees and Other Compensation

         USE pays non-employee directors a fee of $150 per meeting attended. All
directors are reimbursed for expenses incurred with attending meetings.


                                       73

<PAGE>



         Non-employee  directors  are  compensated  for  services  with $400 per
month, payable each year by the issue of shares of USE Common Stock based on the
closing  stock market price as of January 15. In 1998,  2,560 shares were issued
to  non-employee  directors  for  service in 1997.  Separately,  Mr.  Fraser,  a
director,  and the Honorable  Alan K. Simpson,  Chairman of the Advisory  Board,
each received  2,500 shares of USE Common Stock for services in fiscal 1998. The
2,500 shares  issued to Mr.  Fraser were in addition to shares  issued under the
monthly service plan.

         In fiscal 1990, the Board  authorized  the Executive  Committee to make
loans to members of the Board, or to guarantee  their  obligations in amounts of
up to $50,000,  if such  arrangements  would benefit USE. USE loaned  $25,000 to
David W. Brenman under this plan in fiscal 1991.  The loan to Mr.  Brenman bears
interest at the prime rate of the Chase  Manhattan Bank and was due September 1,
1994,  but has been  extended to September  30, 1999 by Board vote (Mr.  Brenman
abstaining).  The loan was provided as partial  consideration  for Mr. Brenman's
representation of USE to the financial community in New York City.

Executive Compensation - YSFC

         For the year  ended  May 31,  1998,  the  officers  of YSFC  were  paid
salaries as follows:  Mark J. Larsen,  president ($90,000 including $22,500 from
USE), Peter  Schoonmaker  ($90,000  including $22,500 from USE), and Fred Craft,
vice president ($65,000 including $32,500 from USE).

Certain Relationships and Related Transactions

         Transactions  with Yellow  Stone Fuels Corp.  Yellow Stone Fuels Corp.,
hereafter ("YSFC") was organized on February 17, 1997 in Ontario,  Canada. As of
February 17, 1997, YSFC acquired all the  outstanding  shares of Common Stock of
Yellow Stone Fuels,  Inc. (a Wyoming  corporation which was organized on June 3,
1996) in  exchange  for YSFC  issuing the same number of shares of YSFC Stock to
the former  shareholders  of Yellow  Stone  Fuels,  Inc.  ("YFI").  YSFC and its
wholly-owned  subsidiary  Yellow Stone Fuels, Inc. will hereafter be referred to
collectively as YSFC.

         On May 15, 1997,  YSFC entered into a line of credit  arrangement  with
USECC. As of November 30, 1998, YSFC owed USECC $460,000 which included  $60,000
of accrued interest.  This loan bears interest at 10% and is due on December 31,
1998.  The loan was made to  provide  working  capital  to YSFC in its  start up
phase.  In early 1999,  USE,  Crested and YSFC  amended the note for the loan to
allow USE and Crested  the right to be paid,  at their  election,  not more than
$200,000 of the principal and accrued interest in cash; the balance will be paid
in YSFC  shares  of  Common  Stock,  at the rate of 1 share  for  each  $1.50 of
remaining  principal  and  interest (if USE and Crested have been paid less than
$100,000 in cash), or 1 share for each $2.00 of remaining principal and interest
(if USE and Crested  have been paid more than  $100,000  in cash,  not to exceed
$200,000 in cash).  The original $1.00  conversion price was negotiated based on
the high risk of the loan during  YSFC's start up phase.  As part  consideration
for the loan, USE and Crested  entered into a Voting Trust  Agreement  having an
initial term of 24 months or until the loan is paid, with USE and Crested having
voting control of more than 50% of the outstanding  shares of YSFC. The majority
of the remaining  outstanding YSFC shares are owned by family members of John L.
Larsen,  Chairman  of USE.  The  changes  to the  note  effected  in  1999  were
negotiated  by those  directors of USE and Crested who are not  shareholders  or
officers or directors of YSFC.

         YSFC also owed USECC  $117,800 in accrued  expenses  that USECC paid on
behalf of YSFC.

         Transactions with Directors. Two of USE's directors, Messrs. Larsen and
Herron, and one of Crested's directors,  Max T. Evans, are trustees of the ESOP.
Mr.  Larsen  is also a  director  of  Crested.  In that  capacity  they  have an
obligation to act in the best interests of the ESOP participants.  This duty may
conflict

                                       74

<PAGE>



with their obligations as directors of USE in times of adverse market conditions
for the Common  Stock,  or in the event of a tender  offer or other  significant
transaction.

         In general,  the ESOP trustees exercise  dispositive powers over shares
held by the ESOP,  and exercise  voting  powers with respect to ESOP shares that
have not been allocated to a participant's  account. In addition, the Department
of Labor has taken the position that in certain  circumstances ESOP trustees may
not  rely  solely  upon  voting  or  dispositive  decisions  expressed  by  plan
participants,  and must  investigate  whether  those  expressions  represent the
desires of the participants, and are in their best interests.

         Harold F. Herron,  son-in-law of John L. Larsen, had been living in and
caring for a house  owned by USE until such time as the  property  was sold.  In
fiscal 1995, Mr. Herron purchased the house for $260,000, the appraised value of
the property,  and was  reimbursed by USE for  leasehold  improvements  totaling
$22,830.  USE accepted a promissory note in the amount of $112,170 with interest
compounded  annually  at 7% due  on  September  6,  1999  as a  result  of  this
transaction.  This note is secured by 30,000 shares of USE common stock owned by
Mr. Herron and its interest is favorable to USE.

         Other Information.  USE has adopted a stock repurchase plan under which
it may purchase up to 500,000  shares of its Common Stock at market  prices from
time to time. The shares  purchased would be retired and canceled.  The Board of
Directors  believes  that the  repurchase  plan is in the best  interest  of all
shareholders while the stock is trading at low prices relative to the book value
per share.  Through November 30, 1998 45,700 shares had be repurchased at a cost
of $123,800.

         In May 1998,  USE issued a warrant to  purchase  200,000  shares of USE
Common Stock to Robin J. Kindle,  an employee of USE and a son-in-law of John L.
Larsen.  The exercise price is $7.50 per share,  and the warrant  expires in May
2001.

         Three of John L.  Larsen's sons and three  sons-in-law  are employed by
USE or subsidiaries  (as President,  President of YSFC,  Vice  President,  chief
pilot, landman, and manager of the Ticaboo operations).  Mr. Larsen's son-in-law
Harold F. Herron is an officer and  director  of USE,  and  Chairman of Brunton.
Collectively,  the six  individuals  and John L. Larsen  received  $1,418,605 in
total  (gross) cash  compensation  ($1,301,605  net after taxes) for services in
fiscal 1998, including the $732,000 bonus paid to John L. Larsen in fiscal 1998.
See "Executive Compensation Plans and Employment Agreements."

         USE and Crested  provide  management  and  administrative  services for
affiliates  under the terms of  various  management  agreements.  Revenues  from
services by USE and Crested  from  unconsolidated  affiliates  were  $857,600 in
fiscal 1998 and  $397,700 in fiscal 1997.  USE  provides  all employee  services
required by Crested,  which is  obligated  to USE for its share of the costs for
providing such employees.

         Transactions  Involving  USECC.  USE and Crested  conduct most of their
activities through their equally-owned  joint venture,  USECC. From time to time
USE and  Crested  advance  funds  to or make  payments  on  behalf  of  USECC in
furtherance  of their joint  activities.  These  advances  and  payments  create
intercompany  debt  between  USE and  Crested.  The  party  extending  funds  is
subsequently  reimbursed  by the other  venturer.  USE had a note  receivable of
$6,547,100  from Crested at May 31, 1998  ($6,023,400 at May 31, 1997).  Crested
presently  does not have the cash funds to pay the note.  USE and  Crested  have
agreed that USE  extending  its funds and taking a note therefor from Crested is
preferable to Crested's share of the different activities being reduced.

         Loans to Directors.  As of May 31, 1998 two of USE's directors owed USE
as follows (each loan is secured with shares of Common Stock of USE owned by the
individual):  Harold F. Herron  $11,000  (1,000  shares);  and David W.  Brenman
$25,000 (4,000 shares). Max T. Evans, a director of Crested,  owes USECC $22,700
(secured  by 7,500  shares  of  USE's  Common  Stock).  For  information  on Mr.
Brenman's loan see

                                       75

<PAGE>



"Directors' Fees and Other  Compensation"  above. The outstanding amounts on the
remaining loans represent various loans made to the individuals over a period of
several years.  Mr.  Herron's and Evans' loans mature December 31, 1998 and bear
interest at 10% per year. For  information on an additional  loan to Mr. Herron,
see below.  These loans all bear  interest at rates which are  favorable to USE,
were made on a secured basis, and were approved by the  disinterested  directors
in each instance.  In addition,  at May 31, 1997,  John L. Larsen and members of
his immediate family were indebted to USE for $745,300 secured by 160,000 shares
of USE's Common Stock.  In fiscal 1998,  John L. Larsen  repaid  $410,837 of the
family debt,  so the family debt at May 31, 1998 was  $338,297.  See  "Executive
Compensation  Plans and  Employment  Agreements."  The preceding  amounts do not
include the loan to Mr. Herron, see below.

         In fiscal 1995, USE made a five year non-recourse loan in the amount of
$112,170  to Harold F.  Herron.  The loan is secured  by 30,000  shares of USE's
Common  Stock,  bears  interest at a rate of 7% and is payable at maturity.  The
Board approved the loan to obtain a higher  interest rate of return on the funds
compared to commercial rates, and to avoid having the USE stock prices depressed
from Mr. Herron selling his shares to meet personal obligations. In fiscal 1999,
USE loaned Mr. Herron $125,000 with interest at 9%; the debt is due on or before
December 31, 1999 and is secured with personal property of Mr. Herron.

be noted that voting and dispositive powers for certain shares are shared by two

having  a  shared  interest   therein,   but  are  only  included  once  in  the

                    Report of Independent Public Accountants


To U.S. Energy Corp.:

We have audited the  accompanying  consolidated  balance  sheets of U.S.  ENERGY
CORP. (a Wyoming  corporation) AND SUBSIDIARIES as of May 31, 1998 and 1997, and
the related consolidated statements of operations, shareholders' equity and cash
flows for each of the  three  years in the  period  ended  May 31,  1998.  These
financial   statements  are  the   responsibility  of  USE's   management.   Our
responsibility  is to express an opinion on these financial  statements based on
our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all  material  respects,  the  financial  position  of  U.S.  Energy  Corp.  and
subsidiaries  as of May 31, 1998 and 1997,  and the results of their  operations
and their  cash flows for each of the three  years in the  period  ended May 31,
1998, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  MAY 31, 1998


A.       BUSINESS ORGANIZATION AND OPERATIONS:

         U.S.  Energy Corp.  (the  "Company" or "USE") was  incorporated  in the
State of Wyoming on January 26, 1966. USE's primary business is the acquisition,
exploration,  holding,  sale and/or development of mineral properties and mining
and marketing of minerals. Principal mineral interests are in uranium, gold, and
molybdenum.  USE  also  holds  various  real  and  personal  properties  used in
commercial  activities  and operates an airport fixed base facility in Riverton,
Wyoming.  Most of these  activities  are  conducted  through  the joint  venture
discussed  below  and in  Note  D.  USE,  through  its  previously  wholly-owned
subsidiary,  The Brunton Company  ("Brunton"),  which was sold in February 1996,
engaged in the  manufacturing and marketing of compasses and the distribution of
outdoor  recreational   products.  In  addition,   through  its  majority  owned
subsidiary,  Four Nines Gold, Inc. ("FNG"), USE historically engaged in projects
such as the construction of municipal sewage systems, irrigation and other civil
engineering  projects.  At May 31, 1998, FNG was primarily engaged in activities
for USE at its Green Mountain uranium property.

         USE and its 52%-owned subsidiary, Crested Corp. ("Crested") are engaged
in a venture  to develop  certain  uranium  properties  with  Kennecott  Uranium
Company  ("Kennecott")  known as the Green  Mountain  Mining  Venture  ("GMMV"),
formed in 1990, and is also involved in a partnership with Nukem, Inc. ("Nukem")
through its  wholly-owned  subsidiary,  Cycle  Resource  Investment  Corporation
("CRIC"),  known as Sheep Mountain Partners ("SMP"). As discussed in Note K, SMP
is currently  involved in significant  legal  proceedings  between its partners.
During fiscal 1995,  USE and Crested  formed a new Wyoming  corporation,  Sutter
Gold Mining  Company  ("SGMC"),  which was the  successor  of USECC Gold Limited
Liability  Company  ("USECC  Gold")  and  Sutter  Gold  Venture  ("SGV").  These
companies were formed to develop and mine gold reserves in California.  USE also
owns 100% of the outstanding  stock of Plateau  Resources  Limited  ("Plateau"),
which owns a nonoperating  uranium mill and support  facilities in  southeastern
Utah.  Currently,  the mill is  nonoperating  but has been  granted a license to
operate, pending certain conditions. See further discussion of these entities in
Note  F. As  used,  hereafter,  "Company"  refers  to USE  and its  consolidated
entities unless otherwise specified.

Liquidity and Operating Losses

         As a  result  of the SMP  litigation/arbitration  (see  Note K) and the
significant  amount of  standby/maintenance,  permitting and  development  costs
being incurred on USE's mineral  properties  (none of which are in  production),
USE has incurred  significant  losses from continuing  operations during each of
the last three years. During the past few years, USE has relied primarily on the
sale of its common stock through  private  placements and the exercise of common
stock  warrants/options,  borrowing  on its lines of credit,  term loans and the
sale of its  subsidiary,  Brunton,  to fund its  losses and cash  needs.  During
fiscal 1998,  USE  received  $858,700  for a delivery  made on an SMP  contract.
Subsequent to year end, USE and Crested  received  $5,026,000 as partial payment
of the monetary resolution of the American  Arbitration  Association's Order and
Award for the portion of the SMP arbitration/litigation  ("SMP litigation") that
was finalized in fiscal 1998.  For  accounting  purposes,  USE and Crested first
applied  the  proceeds  against  their  recorded  investment  balance  in SMP of
$436,000, with the remaining balance of $4,590,000,  after cost recovery,  being
recognized as income. These transactions have resulted in USE having net working
capital of $8,238,900 as of May 31, 1998.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  MAY 31, 1998
                                   (Continued)

         USE anticipates  obtaining additional funds from those issues presently
on appeal before the 10th Circuit  Court of Appeals in  connection  with the SMP
litigation, as further discussed in Note K. If the anticipated award is delayed,
reduced or overturned,  additional  sources of funding will be required to place
Plateau into  production as well as to purchase the  Kennecott  interest in GMMV
(see Note F). Equity and/or debt  financing  will be the primary source of these
funds. There is no assurance such financing sources will be available to USE. If
the additional financings do not occur as planned, USE believes it can delay its
development  activities so that  available  cash,  operating  cash flow and bank
borrowings  will be  adequate  to fund  its  working  capital  requirements  and
commitments for fiscal 1999.

B.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Principles of Consolidation

         The consolidated financial statements of USE and affiliates include the
accounts of USE, the accounts of its majority-owned subsidiaries Plateau (100%),
Energx,  Ltd ("Energx")  (90%), FNG (50.9%),  SGMC (59%),  Crested (52%) and the
USECC Joint Venture  ("USECC"),  a  proportionately  consolidated  joint venture
which  is  equally  owned by USE and  Crested  through  which  the bulk of their
operations are conducted.  USECC owns the buildings and other  equipment used by
USE and holds an  interest  in SMP (see Notes E and F). The  accounts of Brunton
have been reflected as discontinued  operations in the 1996 financial statements
as Brunton was sold in February 1996.

         With the exception of SMP,  investments in other joint ventures and 20%
to 50% owned companies are accounted for by the equity method (see Note E). SGMC
was an equity  investee  through March 1998 when USE purchased  special  warrant
units from certain  investors  and  increased  its  ownership to 59%,  requiring
consolidation of April and May 1998 operations (see Note F). Investments of less
than 20% in  companies  are  accounted  for by the  cost  method.  All  material
intercompany profits, transactions and balances have been eliminated.

Cash Equivalents

         USE considers all highly liquid investments with original maturities of
three  months  or less to be  cash  equivalents.  The  carrying  amount  of cash
equivalents  approximates  fair  value  because of the short  maturity  of these
instruments.

Investments

         Based on the provisions of Statement of Financial  Accounting Standards
("SFAS")  No. 115,  USE accounts for its  investment  in certain  securities  as
held-to-maturity. Held-to-maturity securities are measured at amortized cost and
are carried at the lower of aggregate cost or fair market value.

                                  MAY 31, 1998
                                   (Continued)

Inventories

         Inventories  consist  primarily of aviation fuel,  associated  aircraft
parts, mining supplies,  stockpiled uranium and gold ore. Retail inventories are
stated using the average cost method.  Other inventory is stated at the lower of
cost or market.

Properties and Equipment

         Land, buildings, improvements, aircraft and other equipment are carried
at cost.

         Depreciation of buildings,  improvements,  aircraft and other equipment
is provided  principally by the straight-line method over estimated useful lives
ranging from three to 45 years.

         USE capitalizes all costs incidental to the acquisition and development
of mineral  properties as incurred.  Mineral  exploration  costs are expensed as
incurred.  The costs of mine development are deferred until production begins as
these costs will be recovered through future mining operations.  Once commercial
production begins,  mine development costs incurred to maintain  production will
be amortized using a units-of-  production method over the estimated useful life
of the ore-body.  Costs are charged to operations if USE determines  that an ore
body is no longer  economical.  Costs and expenses related to general  corporate
overhead are expensed as incurred.

         USE and Crested have acquired  substantial  mining  property assets and
associated  facilities at minimal cash cost, primarily through the assumption of
reclamation and environmental liabilities.  Certain of these assets are owned by
various ventures in which USE is either a partner or venturer.  The market value
of these  assets are not  reflected  in the  accompanying  consolidated  balance
sheets (see Note K).

Long-Lived Assets

         USE  evaluates  its  long-lived  assets for  impairment  when events or
changes in  circumstances  indicate that the related  carrying amount may not be
recoverable  based upon an  assessment  of  estimated  future cash flows or fair
market  value,  whichever  is  more  objectively  ascertainable.  If the  sum of
estimated  future cash flows on an undiscounted  basis or the fair value is less
than the carrying amount of the related asset, an asset impairment is considered
to exist. The related impairment loss is measured by comparing  estimated future
cash flows on a discounted basis or the fair value of the asset less any selling
costs to the carrying  amount of the asset.  Changes in significant  assumptions
underlying  future  cash flow  estimates  or fair  values  of assets  may have a
material  effect on USE's  financial  position and results of operations.  A low
commodity  price  market,  if  sustained  for an  extended  period of time or an
inability to obtain financing  necessary to develop mineral interests may result
in asset  impairment.  During 1998,  USE recorded an impairment of $1,500,000 on
its investment in SGMC (see Note F).

Fair Value of Financial Instruments

         The recorded  amounts for short-term and long-term  debt,  receivables,
other current assets, and accounts payable and accrued expenses approximate fair
value.

                                   (Continued)

Revenue Recognition

         Advance  royalties  which are payable  only from future  production  or
which are non-refundable are recognized as revenue when received (see Note F).

         Revenues  from gold and uranium  sales are  recognized  upon  delivery.
Revenues  are  recognized  from the rental of certain  assets  ratably  over the
related  lease terms.  Revenues  from  commercial  operations,  which  represent
primarily  real  estate  activity,  and an  airport  fixed base  operation,  are
recognized  as  goods  and  services  are  delivered.  Revenues  from  long-term
construction  contracts are recognized on the percentage-of-  completion method.
If estimated total costs on any contract indicate a loss, USE provides currently
for the total anticipated loss on the contract.

Income Taxes

         USE  accounts  for  income  taxes in  accordance  with  SFAS  No.  109,
"Accounting for Income Taxes." This statement  requires  recognition of deferred
income  tax  assets  and   liabilities   for  the  expected  future  income  tax
consequences,  based on enacted tax laws, of temporary  differences  between the
financial reporting and tax bases of assets, liabilities and carryforwards.

         SFAS 109 requires  recognition  of deferred tax assets for the expected
future effects of all deductible temporary  differences,  loss carryforwards and
tax credit carryforwards.  Deferred tax assets are reduced, if deemed necessary,
by  a  valuation  allowance  for  any  tax  benefits  which,  based  on  current
circumstances, are not expected to be realized.

Net Income (Loss) Per Share

In February 1997, SFAS No. 128 "Earnings per Share" was issued and specifies the
computation,  presentation  and disclosure  requirements for earnings per share.
SFAS 128 is  effective  for periods  ended after  December 15, 1997 and requires
retroactive  restatement  of prior  period  earnings  per share.  The  statement
replaces  "primary  earnings  per share"  with  "basic  earnings  per share" and
replaces "fully diluted  earnings per share" with "diluted  earnings per share."
Adoption  of SFAS  128  required  restatement  of 1997  earnings  per  share  as
forfeitable  shares were included in the  calculations  of primary  earnings per
share for the year  ended May 31,  1997,  the loss per share was (.55)  prior to
restatement.  The following table presents a reconciliation of basic and diluted
earnings per share calculations:

Recent Accounting Pronouncements

         In June 1997,  SFAS No. 130  "Reporting  Comprehensive  Income"  ("SFAS
130")  was  issued  and  establishes  standards  for  reporting  and  displaying
comprehensive income and its components in the financial statements. In addition
to net income,  comprehensive  income  includes  all changes in equity  during a
period,  except those resulting from investments by and distributions to owners.
USE will adopt SFAS 130,  which is effective  for fiscal years  beginning  after
December 15, 1997,  in the first  quarter of fiscal  1999.  Management  does not
expect the  adoption  of this  pronouncement  to have a  material  impact on its
consolidated financial statements.

         In  June  1997,  SFAS  No.  131,  "Disclosures  about  Segments  of  an
Enterprise  and Related  Information"  ("SFAS  131") was issued and  establishes
standards  for  reporting  information  about  operating  segments in annual and
interim financial  statements.  SFAS 131 also establishes  standards for related
disclosures  about products and services,  geographic areas and major customers.
SFAS 131 is effective for fiscal years  beginning  after  December 15, 1997, and
will be adopted in fiscal 1999. Reporting and disclosures under SFAS 131 are not
expected to be materially different than those disclosures in Note I.

         In February 1998, SFAS No. 132 "Employers'  Disclosures  about Pensions
and Other Post  Retirement  Benefits"  ("SFAS 132") was issued and  standardizes
disclosure  requirements  for pension and other post  retirement  benefit plans.
Adoption of this standard is required for fiscal years  beginning after December
15, 1997, and restatement of prior period  comparative  disclosures is required.
USE will adopt SFAS 132 in fiscal 1999. The adoption of SFAS 132 is not expected
to materially affect USE's disclosures.

         In June 1998, the Financial  Accounting Standards Board issued SFAS No.
133,  "Accounting  for  Derivative  Instruments  and Hedging  Activities"  which
establishes  accounting and reporting  standards for derivative  instruments and
for hedging  activity.  SFAS 133 is  effective  for all periods in fiscal  years
beginning  after June 15,  1999.  SFAS No. 133 requires  all  derivatives  to be
recorded on the balance  sheet as either an asset or  liability  and measured at
fair value.  Changes in the derivative's fair value will be recognized currently
in earnings  unless  specific  hedge  accounting  criteria are met. USE does not
expect  the  adoption  of SFAS 133 to have a  material  effect on its  financial
position or results of operations.

                                   (Continued)

Use of Estimates

         The  preparation of financial  statements in conformity  with generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions.  These  estimates and  assumptions  affect the reported  amounts of
assets and  liabilities  and disclosure of contingent  assets and liabilities at
the date of the financial  statements,  and the reported amounts of revenues and
expenses  during the reporting  period.  Actual  results could differ from those
estimates.

Reclassifications

         Certain reclassifications have been made to the 1997 and 1996 financial
statements to conform with the 1998 presentation.

C.       RELATED-PARTY TRANSACTIONS:

         USE and Crested  provide  management  and  administrative  services for
affiliates under the terms of various management  agreements.  USE also provides
all employee services required by Crested. In exchange,  Crested is obligated to
USE  for  its  share  of  these  costs.   Revenues   from  services  by  USE  to
unconsolidated  affiliates  were $849,000,  $397,000 and $92,900 in fiscal 1998,
1997  and  1996,   respectively.   USE  has  $1,604,400  of   receivables   from
unconsolidated  subsidiaries  and  short-term  advances  to  employees  totaling
$101,300 as of May 31, 1998.

         At May 31, 1998,  USE's principal  shareholder and his immediate family
were  indebted to USE in the amount of $338,000  which is  represented  by notes
secured by 104,000 shares of USE's common stock.

         On May 15,  1997,  Yellow  Stone  Fuels Corp.  ("YSFC"),  a 12.7% owned
affiliate of USE and a 12.7% owned affiliate of Crested,  entered into a line of
credit  arrangement  with USECC.  As of May 31, 1998,  YSFC owed USECC  $440,000
which included $40,000 of accrued interest.  This note bears interest at 10% and
is due on December 31, 1998. In lieu of paying the note in cash on or before its
maturity  date,  YSFC may convert this debt, at its option,  into YSFC shares of
common stock at $1.00 per share of debt and interest.  However, if YSFC defaults
in paying the note by December 31, 1998, the note is  convertible  into a number
of shares which will give USE and Crested a combined 51%  ownership  interest in
YSFC.  USE has  classified the $440,000 note as an investment in YSFC based upon
YSFC's current financial condition.

D.       USECC JOINT VENTURE:

         USECC operates the Glen L. Larsen office  complex;  an aircraft  hangar
with a fixed base operation,  office space and certain aircraft; holds interests
in various mineral properties and ventures including SMP and GMMV;  conducts oil
and gas operations; and transacts all operating and payroll expenses, except for
specific  expenses  allocated  directly  to each  venturer.  The  joint  venture
agreement  also  provides for the  allocation of certain  operating  expenses to
other  affiliates.  In addition,  through April 1996,  USECC operated Wind River
Estates ("Wind  River"),  a 100 unit mobile home park.  During 1996,  USECC sold
Wind River (which had a net book value of approximately $512,700) and recognized
a gain of  $252,600,  which  is  reflected  as a Gain on Sale of  Assets  in the
accompanying Consolidated Statements of Operations.

E.       INVESTMENTS AND ADVANCES:

         USE's  restricted  investments  secure various  decommissioning  costs,
reclamation  and holding  costs.  Investments  are comprised of debt  securities
issued by the U.S.  Treasury  that mature at varying  times from three months to
one year from the original  purchase  date. As of May 31, 1998, the cost of debt
securities  was  a  reasonable   approximation  of  fair  market  value.   These
investments are classified as  held-to-maturity  under SFAS 115 and are measured
at amortized cost.

         USE's investment in and advances to affiliates are as follows:

         GMMV  expenses  certain  general and  administrative,  maintenance  and
holding costs.  However,  USE has not  recognized  equity losses in GMMV because
Kennecott was committed to fund 100% of the first $50,000,000 of development and
operating  costs of the Joint  Venture.  In 1998,  USE and USECC entered into an
Acquisition  Agreement  with  Kennecott  whereby  USE may be  able  to  purchase
Kennecott's  interest  in the GMMV (see  Note F).  USE's  carrying  value of its
investment  in  GMMV  of  $724,800  in  the   accompanying   balance  sheets  is
substantially lower than its underlying equity in GMMV.

         Condensed  combined  statements of operations of USE's equity investees
include GMMV, YSFC and Ruby Mining Company.

         SMP  entered  into  various  market  related  and base price  escalated
uranium sales  contracts  with certain  utilities  which  require  approximately
1,500,000 pounds of uranium  concentrates to be delivered from 1997 through 2000
depending on utility requirements. These contracts also allow for the quantities
to be substantially  increased by the utilities. As discussed in Note K, SMP has
been the subject of significant  litigation and arbitration  proceedings between
the SMP partners since 1991,  portions of which are currently still in progress.
Pending the resolution of the remaining proceedings,  the partners in SMP agreed
to  fulfill  certain  of  the  SMP's  uranium  sales  contracts  outside  of the
partnership  with each  partner  delivering  a mutually-  agreed  portion of the
delivery  commitments on an individual  basis.  In 1998 and 1996, USE recognized
revenues of $858,700 and  $1,383,400,  respectively  (no related  revenues  were
recognized in 1997) from these deliveries. Revenues from these transactions have
been  included in the  accompanying  Consolidated  Statements  of  Operations as
Mineral Sales, which would normally have been sales of SMP.

         Due to the litigation and arbitration  proceedings,  audited  financial
statements for SMP are not  obtainable.  Accordingly,  USE has recorded only its
direct investment in, and results of operations from the partnership. USE had no
carrying value of its investment in SMP for either 1998 or 1997 as proceeds from
litigation  and  arbitration  proceedings  were  accounted  for  under  the cost
recovery  method  of  accounting  as  discussed  in Note K.  USE's  direct  loss
generated  from its  investment  in SMP,  which  represent  mine  standby  costs
incurred by USE, was $436,000, $442,700 and $416,200 for the years ended May 31,
1998, 1997 and 1996,  respectively.  No amounts attributable to SMP are included
in the Condensed  Combined  Balance Sheets or Condensed  Combined  Statements of
Operations of USE's equity investees presented above.

F.       MINERAL CLAIMS TRANSACTIONS AND MINING PROPERTIES:

GMMV

         During  fiscal 1990,  USE and Crested  entered  into an agreement  with
Kennecott,  a wholly-owned,  indirect subsidiary of The RTZ Corporation PLC, for
Kennecott to acquire a 50% interest in certain  uranium  mineral  properties  in
Wyoming  known  as  the  Green  Mountain  Properties.  The  purchase  price  was
$15,000,000  and a commitment to fund the first $50 million of  development  and
operating  costs.  Kennecott  committed to fund 100% of the first $50 million of
capital  contributions  to the GMMV.  Kennecott also committed to pay additional
amounts  if  certain  future  operating  margins  are  achieved.  USE and  USECC
participate in cash flows of the GMMV in accordance  with their ownership of the
mining claims prior to the formation of the GMMV.

         On June 23, 1997,  USE and USECC signed an  Acquisition  Agreement with
Kennecott  for the  right  to  acquire  Kennecott's  interest  in the  GMMV  for
$15,000,000 and other consideration.  Kennecott paid USE and USECC $4,000,000 on
signing,  and  committed  to loan  the GMMV up to  $16,000,000  for  payment  of
reimbursable  costs  incurred by USECC in  developing  the proposed  underground
Jackpot Uranium Mine for production and in changing the status of the Sweetwater
Mill from standby to operational.

         Pursuant to the Acquisition Agreement,  the Mineral Lease, and the Mill
Contract,  USECC is to develop the  proposed  Jackpot  Mine and nearby Big Eagle
Mine,  and work with  Kennecott in  preparing  the  Sweetwater  Mill for renewed
operations.  Such work will be funded from the  $16,000,000  being loaned to the
GMMV by Kennecott.  Kennecott will be entitled to a credit  against  Kennecott's
original  $50,000,000  commitment to fund the GMMV, in the amount of two dollars
of credit  for each one dollar of such  funds out of the  $16,000,000  loaned by
Kennecott to the GMMV,  plus the $4,000,000  paid to USE and USECC on signing of
the  Acquisition  Agreement.  It is  anticipated  that such  credits  will fully
satisfy the balance of Kennecott's initial funding commitment to the GMMV.

         Closing  of the  Acquisition  Agreement  is  subject  to USE and  USECC
satisfying several conditions, including: (i) the acquiring entity (which may be
USE, USECC, or an entity formed by USE and USECC to acquire Kennecott's interest
in the GMMV) must have a market  capitalization of at least  $200,000,000;  (ii)
the parties to the Acquisition  Agreement must have received all authorizations,
consents,  permits and  approvals of  government  agencies  required to transfer
Kennecott's  interest in the GMMV to the acquiring  entity;  (iii) USE and USECC
shall have replaced, or caused the replacement of, approximately  $25,000,000 of
reclamation  bonds,  in  addition  to  other  guarantees,   indemnification  and
suretyship  agreements  posted by Kennecott on behalf of the GMMV;  and (iv) USE
and USECC, or the acquiring  entity,  must pay $15,000,000  cash to Kennecott at
closing and assume all  obligations and liabilities of Kennecott with respect to
the GMMV (including repayment of the $16,000,000 Note and the Mortgage) from and
after the closing. Under very limited circumstances,  the scheduled closing date
may be postponed to not later than October 30, 1998.

         USECC  satisfied  the terms of the  Acquisition  Agreement to the point
that the $4,000,000  deferred GMMV purchase  option benefit paid by Kennecott is
nonrefundable and will serve to reduce USE's and Crested's ultimate  $15,000,000
purchase price. If the acquisition is unsuccessful,  the signing payment will be
applied against any future  reimbursable  costs and  contributions due the GMMV.
After such costs and remaining obligations are satisfied, the remainder, if any,
will be recognized as income.

                                   (Continued)

         In 1996, the U.S.  Government  adopted the "USEC  Privatization  Act of
1996" to privatize the U.S. Enrichment Corp. ("USEC").  In July 1998, in filings
with the U.S.  Securities  and Exchange  Commission,  USEC disclosed its planned
sale of significant quantities of uranium in the U.S. marketplace.  Accordingly,
forecasted demand for uranium and forecasted uranium sales prices have decreased
in the  short-term.  As a result,  on July 31,  1998,  GMMV  halted  development
activities  at the Jackpot Mine and has placed the  facility on active  standby.
This action  required the layoff of mine workers.  Due to the uncertainty of the
uranium  market,  it is not known when the mine will  operate  again or if USECC
will be able to conclude the financing necessary to buy Kennecott's interest.

         If the  Acquisition  Agreement is not closed,  USE, USECC and Kennecott
shall  continue  to  own  their  respective  50%  interests  in  the  GMMV,  and
Kennecott's  obligation  to repay the  $16,000,000  loaned  by KEC shall  remain
Kennecott's  obligation,  without any adverse effect on the 50% interest in GMMV
held by USE and USECC. However, the Jackpot Mine development work and Sweetwater
Mill upgrade work funded by the  $16,000,000  advance will have  benefitted  all
parties  to the GMMV and will fully  satisfy  Kennecott's  original  $50,000,000
funding obligation to GMMV.

SMP

         During fiscal 1989,  USE and Crested,  through  USECC,  entered into an
agreement to sell a 50% interest in their Sheep  Mountain  properties to Nukem's
subsidiary CRIC. USECC and CRIC immediately  contributed  their 50% interests in
the  properties  to a  newly-formed  partnership,  SMP. SMP was  established  to
further develop and mine the uranium claims on Sheep  Mountain,  acquire uranium
supply contracts and market uranium.  Certain  disputes arose among USECC,  CRIC
and its parent Nukem,  Inc. over the operation of SMP.  These disputes have been
in  litigation/arbitration  for the past  seven  years.  See Notes E and K for a
description    of   the   investment   and   a   discussion   of   the   related
litigation/arbitration.

CYPRUS AMAX

         During prior years, USE and Crested conveyed interests in mining claims
to AMAX Inc. ("AMAX") in exchange for cash, royalties,  and other consideration.
AMAX and its  successor  Cyprus Amax  Minerals,  Inc.  ("Cyprus  Amax") have not
placed the properties into production as of May 31, 1998.

         Cyprus  Amax now pays USE and  Crested  an annual  advance  royalty  of
50,000 pounds of molybdenum (or its cash equivalent). Cyprus Amax is entitled to
a partial credit against future royalties for any advance royalty payments made,
but such  royalties  are not  refundable if the  properties  are not placed into
production.  USE  recognized  $211,000,  $207,300  and $-0- of revenue  from the
advance royalty payments in fiscal 1998, 1997, and 1996, respectively.

         Cyprus  Amax may elect to return  the  properties  to USE and  Crested,
which  would  cancel the advance  royalty  obligation.  If Cyprus Amax  formally
decides to place the properties into  production,  it will pay $2,000,000 to USE
and Crested.  If Cyprus Amax sells the properties,  USE and Crested will receive
15% of the first $25 million received by Cyprus Amax.

         USE and  Crested  also held an option to purchase  certain  real estate
located in Gunnison,  Colorado owned by Cyprus Amax. During fiscal 1995, USE and
Crested reached an agreement with Cyprus Amax

whereby USE and  Crested  would  forego six  quarters  of advance  royalties  as
payment of this option exercise price. Accordingly,  USE and Crested received no
advance  royalties  during 1996 as a result of this agreement.  Thereafter,  USE
(together with Crested) signed two option  agreements with Pangolin  Corporation
("Pangolin"),  a Park  City,  Utah  developer,  for  sale of the  land  owned in
Gunnison.  Pangolin  made a cash  payment  and signed  promissory  notes for the
purchase of the  properties.  As of May 31, 1998, the  promissory  notes were in
default and are  adequately  reserved for.  USECC is  endeavoring to resolve the
default and filed a legal action to protect its interest (see Note K).

SGMC

         Sutter Gold Mining Company  ("SGMC") was established in 1990 to conduct
operations on mining leases and to produce gold from the Lincoln Project.

         SGMC is in the development stage and additional development is required
prior to the commencement of commercial  production.  SGMC has not generated any
significant revenue and has no assurance of future revenue.  All acquisition and
mine  development  costs  since  inception  have been  capitalized.  Since  test
production in 1992,  SGMC has focused its efforts on obtaining a reserve  study,
developing a mine plan and pursuing a partner to assist in the  financing of its
mineral  development  and ultimate  production.  As of May 31, 1998,  due to the
decline in the spot price for gold,  SGMC has put the development of the mine on
hold.  Until the time when development  begins,  SGMC does not expect to require
capital  contributions  from USE,  Crested  or other  sources  of  financing  to
maintain its current  activities.  SGMC will  continue to be  considered  in the
development  stage  until the time it  generates  significant  revenue  from its
principal operations.

         During the first and second  quarters of fiscal 1997,  SGMC sold shares
of its common stock in a private placement. These shares were sold for $3.00 per
share. SGMC received  approximately  $1,100,000 in net proceeds from this equity
placement.  During the fourth quarter of fiscal 1997, an additional  offering of
shares of SGMC's  special  warrant units was completed and raised  approximately
$5,400,000 in net cash proceeds.  Each special warrant unit is convertible  into
one share of SGMC common  stock for no  additional  consideration  and one stock
purchase warrant.  The warrant allows the holder to purchase an additional share
of SGMC common stock for a CAN$6.00.  The warrant  expires in November  1998. At
the underwriter's  request,  the initial  investors  (including USE and Crested)
agreed to have the amount of their common  shares  owned  reduced by 50 percent.
The investors in the $3.00 per share private placement  discussed above were not
affected  as those  shares  were  sold in  contemplation  of the 1 for 2 reverse
split.

         In  connection  with the second  offering,  USE and Crested  accepted a
Contingent  Stock  Purchase  Warrant dated March 21, 1997 which provides USE and
Crested the right to acquire, for no additional consideration,  common shares of
SGMC's $.001 par value common  stock  having an aggregate  value of  $10,000,000
(US). The Stock Purchase  Warrant has a term of ten years extending to March 21,
2007, and is exercisable partially or in total,  semi-annually beginning on June
30, 1997. However,  the Stock Purchase Warrant is only exercisable to the extent
proven and probable ore reserves,  as defined in the Stock Purchase Warrant,  in
excess of 300,000 ounces are added to SGMC's reserves. In addition, SGMC has the
right to  satisfy  the  exercise  of all or any  portion  of the Stock  Purchase
Warrant with the net cash flows,  as defined,  at $25.00 (US) for each new ounce
of  proven  and  probable  ore in excess of  300,000  ounces up to a maximum  of
700,000 ounces. Accordingly, USE has allocated the carrying value of SGMC shares
exchanged for the

                                   (Continued)

Contingent Stock Purchase Warrant to its investment in such contingent warrants.
The Stock  Purchase  Warrant  benefits  USE and  Crested on a basis of 88.9% and
11.1%, respectively.

         On March 31, 1998,  USE purchased  889,900  Special  Warrant Units from
certain  Canadian  investors.  The units were  purchased  with 488,895 shares of
USE's common stock. In addition,  USE sold 170,000 shares of common stock to the
Canadian  investors at the then market  price ($7.00 per share).  As a result of
this purchase,  USE and Crested's  combined  ownership interest in SGMC was 59%.
Therefore,  as of April 1,  1998  USE  began  consolidating  SGMC's  results  of
operations.  Had USE consolidated SGMC for the entire 12- month period ended May
31, 1998, the 1998 consolidated net loss would have been approximately  $190,000
greater.

         Primarily as a result of the  sustained  decline in gold prices and the
April 1998  issuance  of shares for  additional  equity  interest  in SGMC,  USE
evaluated  the May  31,  1998  carrying  value  of its  investment  in SGMC  for
impairment.  USE determined its aggregate investment in SGMC, which includes the
Stock  Purchase  Warrant  discussed  previously,  exceeded the fair value of the
investment  by  approximately  $1,500,000.  Accordingly,  in  fiscal  1998,  USE
recorded  an  impairment  in the amount of  $1,500,000  which is  classified  as
Impairment of Mineral Interests in the accompanying  Consolidated  Statements of
Operations.

         Additional  financing will be required in order to develop the reserves
of SGMC.  Management  of SGMC is  currently  attempting  to negotiate a proposed
financing  plan to be executed in fiscal  1999.  However,  if  financing  is not
obtained in fiscal  1999,  or should  other  events occur such as a sustained or
further  decline in gold prices,  USE will reevaluate the need for an additional
impairment  of its carrying  value in SGMC. If a  determination  is made that an
impairment  has  occurred,  it is likely the amount of such  impairment  will be
material to USE's financial position and results of operations.

Plateau Resources Limited

         During fiscal 1994, USE entered into an agreement with Consumers  Power
Company  to  acquire  all the issued  and  outstanding  common  stock of Plateau
Resources  Limited  ("Plateau"),  a Utah  corporation.  Plateau  owns a  uranium
processing  mill and support  facilities  and certain  other real estate  assets
through its  wholly-owned  subsidiary  Canyon  Homesteads,  Inc. in southeastern
Utah.  USE paid nominal cash  consideration  for the Plateau stock and agreed to
assume all environmental liabilities and reclamation bonding obligations. At May
31,  1998,  Plateau  had a cash  security in the amount of  $7,270,408  to cover
reclamation of the properties (see Note K).

         USECC is currently evaluating the best utilization of Plateau's assets.
Evaluations  are ongoing to determine  when, or if, the mine and mill properties
should  be placed  into  production.  The  primary  factor in these  evaluations
relates  to the  current  depressed  uranium  market.  Alternative  uses  of the
properties are also being evaluated.

         In fiscal  1998,  USE had an  independent  appraisal  performed  on its
modular homes held for resale. Based upon the analysis performed, USE recorded a
$100,000 write-down to more accurately reflect the fair value of these assets as
of May 31, 1998. The write-down is included in Commercial  Costs and Expenses in
the accompanying Consolidated Statements of Operations.  USE continues to review
its investment in these assets for impairment.

Energx, Ltd.

         Energx is engaged in the  exploration,  development  and  operation  of
natural gas properties. Energx currently has leased properties in Wyoming and on
the Fort Peck Indian Reservation, Montana. Energx is owned by USE (45%), Crested
(45%) and the Assiniboine and Sioux Tribes (10%).

         During fiscal 1997 and 1996, Energx abandoned certain of its leases and
as  a  result  wrote  off  $164,500  and  $328,700,   respectively,  of  related
capitalized  costs.  The  write  off is  reflected  as  Abandonment  of  Mineral
Interests in the accompanying Consolidated Statements of Operations.

G.       DEBT:

Lines of Credit

         USE and Crested  have a  $1,000,000  line of credit  from a  commercial
bank.  The line of credit  bears  interest  at the  bank's  prime  rate plus .5%
(10.25% as of May 31, 1998).  The weighted  average  interest rate for both 1998
and 1997 was 10.25%.  The line of credit is secured by certain real property and
a share of the net proceeds of fees from  production  from certain oil wells. No
amounts were outstanding as of May 31, 1998 and 1997.

Notes Payable

         The  components  of notes  payable  as of May 31,  1998 and 1997 are as

</TABLE>

         USE  has  established  a  valuation  allowance  of  $6,800,300  against
deferred  tax assets due to the losses  incurred  by USE in past  fiscal  years.
USE's ability to generate  future  taxable income to utilize the NOL and capital
loss carryforwards is uncertain.

         The  income tax  provision  (benefit)  is  different  from the  amounts
computed by applying  the  statutory  federal  income tax rate to income  before
taxes. The reasons for these differences are as follows:

         There were no taxes currently  payable as of May 31, 1998, 1997 or 1996
related to continuing operations.

         At May 31, 1998, USE and its  subsidiaries  had available,  for federal
income  tax  purposes,   net  operating  loss   carryforwards  of  approximately
$19,700,000  which  will  expire  from 2004 to 2013 and  investment  tax  credit
carryforwards of $213,800 which, if not used, will expire from 1999 to 2001. The
Internal  Revenue Code  contains  provisions  which limit the NOL  carryforwards
available which can be used in a given year when significant  changes in company
ownership  interests occur. In addition,  the NOL and credit amounts are subject
to examination by the tax authorities.

                                   (Continued)

         The Internal  Revenue  Service has audited  USE's and  affiliates'  tax
returns  through fiscal 1994,  and is currently  auditing the fiscal years ended
May 31, 1996 and May 31, 1995.  USE's income tax liabilities are settled through
fiscal  1992.  USE has  received 30 day letters for the years ended May 31, 1994
and 1993.  USE has  submitted a written  appeal to protest  the  findings of the
examining agent to preserve its NOL. Management believes USE will prevail on the
significant issues in dispute, and therefore, no significant changes will result
from the findings.

I.       SEGMENTS AND MAJOR CUSTOMERS:

         USE's  primary  business  activity  is the  sale  of  minerals  and the
acquisition,  exploration,  holding,  development  and sale of  mineral  bearing
properties  although  USE has no  producing  mines.  Other  reportable  industry
segments include commercial  operations,  primarily real estate  activities,  an
airport fixed base  operation,  and  construction  activities.  The following is
information related to these industry segments:

         During  fiscal  1998 and  1996  approximately  100% and 89% of  mineral
revenues  were from the sale of  uranium.  There  were no uranium  sales  during
fiscal 1997.

         USE  subleases  excess  office  space,  contracts  aircraft for charter
flights  and  sells  aviation  fuel.  Commercial  Revenues  in the  accompanying
Consolidated  Statements  of  Operations  consist of mining  equipment  rentals,
office and other real property rentals, charter flights and fuel sales.

J.       SHAREHOLDERS' EQUITY:

         In May 1996, the Board of Directors of USE approved an annual incentive
compensation arrangement ("1996 Stock Award Program") for its CEO and four other
officers of USE payable in shares of USE's  common  stock.  The 1996 Stock Award
Program was subsequently  modified to reflect the intent of the directors of USE
which was to provide incentive to the officers of USE and Crested to remain with
the companies.  The shares are to be issued  annually on or before January 15 of
each year,  starting  January 15,  1997,  as long as each officer is employed by
USE, provided USE has been profitable in the preceding fiscal year. The officers
will  receive up to an aggregate  total of 67,000  shares per year for the years
1997  through  2002.  One-half  of the  compensation  under the 1996 Stock Award
Program  is the  responsibility  of  Crested.  The  shares  under  the  plan are
forfeitable until retirement, death or disability of the officer. The shares are
held in trust by USE's treasurer and are voted by USE's non-employee  directors.
As of May 31, 1998,  245,378  total shares have been issued to the five officers
of USE and Crested.

                                   (Continued)

         In December 1997, USE entered into a warrant purchase agreement with an
investment  advisory  firm to purchase  225,000  shares at an exercise  price of
$10.50  expiring  December 2, 2000.  The  warrants  were issued in exchange  for
services to be provided  during the period  December 1997 to December  1998. USE
determined the fair value  associated with these warrants to be $186,000,  which
will be  recognized  ratably  over the term of the related  advisory  agreement.
Accordingly,  $108,000  was  recognized  as  expense  in fiscal  1998,  with the
remaining amount to be recognized in fiscal 1999.

         In January 1998,  USE entered into a warrant  purchase  agreement  with
another investment advisory firm to purchase 200,000 shares at an exercise price
of $7.50  expiring  January 20, 2000.  The warrants  were issued in exchange for
services to be provided during the period from January 1998 to January 1999. USE
determined the fair value  associated with these warrants to be $264,000,  which
will be  recognized  ratably  over the term of the related  advisory  agreement.
Accordingly,  $88,000  was  recognized  as  expense  in  fiscal  1998,  with the
remaining amount to be recognized in fiscal 1999.

         In January 1996, USE entered into a warrant purchase  agreement with an
investment  advisory  firm.  Pursuant  to the  Agreement,  this firm  received a
warrant to purchase  200,000  common  shares of USE's  common stock at $5.00 per
share in exchange for  consultation  services to be provided  through January 9,
1997. In connection  with this warrant  agreement,  USE  recognized  $148,300 of
consulting  expense in fiscal  1997 which USE  determined  to be the fair value.
During fiscal 1997, 180,000 of these warrants were exercised  resulting in total
proceeds to USE of $900,000.  The remaining 20,000 shares were exercised in 1998
resulting in $100,000 of proceeds to USE.

         The Board of Directors  adopted the U.S. Energy Corp. 1989 Stock Option
Plan (the  "Option  Plan") for the  benefit of USE's key  employees.  The Option
Plan, amended in December 1995,  reserves 925,000 shares of USE's $.01 par value
common stock for issuance under the Option Plan.  During fiscal 1992, USE issued
options to certain of its executive  officers,  Board members and others.  Under
this Plan,  371,200  non-qualified  options  were issued at prices  ranging from
$2.75 to $2.90 per share.  These options will expire on April 14, 2002 and April
30,  2002.  During  fiscal 1996,  USE issued  360,000  non-qualified  options to
employees  who are not officers or  directors  at a purchase  price of $4.00 per
share, expiring on December 31, 2000. During fiscal 1998, options were exercised
for the purchase of 62,000  shares.  In fiscal  1997,  the  shareholders  of USE
ratified an amendment  to the Option Plan and on that same date all  outstanding
non-qualified  options  were  converted  to  qualified  options  by the Board of
Directors of USE.

         The Board of  Directors  of USE  adopted  the U.S.  Energy  Corp.  1989
Employee  Stock  Ownership  Plan  ("ESOP")  in  1989,  for  the  benefit  of USE
employees.  During  fiscal  1998,  1997 and 1996,  the Board of Directors of USE
contributed  49,470,  24,069 and  10,089  shares to the ESOP at prices of $6.57,
$8.87 and $8.65 per share,  respectively.  USE is  responsible  for  one-half of
these contributions amounting to $162,300,  $106,700 and $43,600 in fiscal 1998,
1997 and 1996,  respectively.  Crested is responsible for the remainder. USE has
loaned the ESOP $1,014,300 to purchase 125,000 shares from USE and 38,550 shares
on the open  market.  These  loans,  which are  secured  by pledges of the stock
purchased  with the loan  proceeds,  bear interest at the rate of 10% per annum.
The loans are reflected as unallocated  ESOP  contribution in the equity section
of the  accompanying  Consolidated  Balance  Sheets.  During  fiscal  1996,  USE
released  10,089 of the shares to fund the 1996 ESOP  contribution by $87,300 as
reflected in the Consolidated Statement of Stockholders' Equity.

                                   (Continued)

         The Board of Directors of both USE and Crested issue shares of stock as
bonuses to certain  directors,  employees  and third  parties.  The stock  bonus
shares have been reflected  outside of the  Shareholders'  Equity section in the
accompanying  Consolidated Balance Sheets because such shares are forfeitable to
USE and Crested  until  earned.  During  fiscal  1993,  USE's Board of Directors
amended  the  stock  bonus  plan.  As a result,  the earn out  dates of  certain
individuals  were extended until  retirement,  which is the earn out date of the
amended  stock bonus plan.  In exchange  for this  amendment,  the amended  plan
grants a  stock-bonus  of 20% of the  previous  plan  per  year for five  years.
Crested is responsible for one half of the compensation expense related to these
issuances. For the years ended May 31, 1998, 1997 and 1996, USE had compensation
expense of $54,600,  $152,600 and $116,500  respectively,  resulting  from these
issuances.  A schedule  of  forfeitable  shares for both USE and  Crested is set
forth in the following table:

Statement of Financial Accounting Standards No. 123 ("SFAS 123")

         SFAS 123,  "Accounting  for Stock-Based  Compensation,"  defines a fair
value based method of accounting  for employee  stock options or similar  equity
instruments.  However, SFAS 123 allows the continued measurement of compensation
cost for such plans using the  intrinsic  value based method  prescribed  by APB
Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB 25"),  provided
that pro forma disclosures are made of net income or loss and net income or loss
per share,  assuming the fair value based  method of SFAS 123 had been  applied.
USE has elected to account for its stock-based  compensation plans under APB 25;
accordingly,  for purposes of the pro forma disclosures presented below, USE has
computed

the fair  values of all  options  granted  during  fiscal  year  1996  using the
Black-Scholes  pricing model and the following weighted average  assumptions (no
options were granted during 1998 and 1997):

                                                               1996

                  Risk-free interest rate                     5.45%
                  Expected lives                              5 years
                  Expected volatility                         135.2%
                  Expected dividend yield                     0%

         To  estimate  expected  lives of  options  for this  valuation,  it was
assumed  options will be exercised  upon becoming fully vested at the end of the
five years. All options are initially assumed to vest.  Cumulative  compensation
cost recognized in pro forma net income or loss with respect to options that are
forfeited prior to vesting is adjusted as a reduction of pro forma  compensation
expense in the period of forfeiture.

         The  total  fair  value  of  options   granted   was   computed  to  be
approximately  $1,274,900  during the year ended May 31,  1996.  This  amount is
amortized ratably over the vesting periods of the options. Pro forma stock-based
compensation,  net of the  effect of  forfeitures,  was  $98,100,  $255,000  and
$106,200 for 1998, 1997 and 1996, respectively.

         If  USE  had  accounted  for  its  stock-based  compensation  plans  in
accordance with SFAS 123, USE's net loss and pro forma net loss per common share
would have been reported as follows:

Sheep Mountain Partners (SMP)

         Arbitration/Litigation   Proceedings  Concerning  SMP.  In  June  1991,
Nukem's wholly-owned  subsidiary Cycle Resource Investment  Corporation ("CRIC")
instituted  arbitration  proceedings against USE and Crested.  CRIC claimed that
USE and  Crested  violated  the  Sheep  Mountain  Partners  ("SMP")  partnership
agreement. On July 3, 1991, USE and Crested, through USECC, filed a civil action
in  the U.  S.  District  Court  of  Colorado  against  Nukem,  CRIC  and  their
affiliates,  alleging Nukem/CRIC fraudulently misrepresented facts and concealed
information  from USE and  Crested to induce  their  entry  into the  agreements
forming the SMP  partnership  and sought  rescission,  damages and other relief.
Certain of Nukem's  affiliates  (excluding CRIC) were thereafter  dismissed from
the lawsuit.  The U. S. District  Court granted the motion of USE and Crested to
stay the above arbitration initiated by CRIC.

                                   (Continued)

         On September  16, 1991,  USECC filed another civil action in the Denver
District Court against SMP seeking  reimbursement of $85,000 per month since the
spring of 1991 for the care and maintenance of the SMP underground uranium mines
and  properties.  On  May  11,  1993,  the  Denver  District  Court  stayed  all
proceedings  in  state  court  until  the case in the U.S.  District  Court  for
Colorado case was resolved.  Thereafter in February 1994, USECC, Nukem and CRIC,
agreed that the majority of the litigation subsequent to the formation of SMP on
December 21, 1988,  would be handled  through  consensual  arbitration  before a
three member panel of the American  Arbitration  Association (the "Panel").  The
arbitration  hearing  consumed 73 hearing days  commencing  on June 27, 1994 and
concluded  on May 31, 1995.  The Panel  entered its Order and Award on April 18,
1996.  Nukem filed two motions with the district  court  indicating  there was a
material  miscalculation and a double recovery.  The District Court remanded the
matter to the Arbitration  Panel to consider Nukem's  motions.  On July 3, 1996,
the Panel found there was no double  recovery  and approved the Order and Award,
which awarded  Crested and USE  $12,500,000  and Nukem/CRIC  $7,100,000  through
March 31, 1996.  On November 4, 1996 the United States  District  Court issued a
Judgment and Order confirming the Arbitration Panel's Order and Award.

         In November  1996,  USE and Crested  received  $4,300,000  from the SMP
escrow bank accounts as partial payment of the monetary award of the Arbitration
Panel.  This  $4,300,000  was accounted  for under the cost  recovery  method of
accounting,  wherein it was applied to outstanding amounts due USECC and USE and
the balance of $1,003,800  was recognized as income.  Nukem/CRIC  filed a motion
asking for limited  remand and on June 27, 1997 the Federal  Court  reviewed the
motion and issued a Second Amended  Judgment which  confirmed the monetary award
of the  Arbitration  Panel and clarified  the  equitable  damages due USECC from
Nukem/CRIC.  Nukem  filed a notice of appeal  with the  Tenth  Circuit  Court of
Appeals and posted a $8,613,600  supersedeas bond on the monetary portion of the
Award.  Nukem's  appeal is based on two  issues,  the  District  Court  erred in
confirming  the double  recovery  finding in the AAA Panel's Order and Award and
that the Order placing Nukem's uranium purchase contracts with the CIS republics
in  constructive  trust with SMP.  During the fourth  quarter of fiscal  1998, a
settlement  agreement  was reached  whereby  U.S.  Energy and  Crested  received
$5,026,000 as a partial  settlement  and, in addition,  USECC received the Sheep
Mountain  Uranium  Mines and certain other  properties  from SMP and one uranium
delivery  contract along with a 50% interest in a uranium supply contract.  This
settlement  does not in any way affect  issues  presently  on appeal and pending
before  the 10th  Circuit  Court of  Appeal  ("CCA").  A  hearing  is  currently
scheduled before a three judge panel court of the 10th CCA on September 24, 1998
in Oklahoma City, Oklahoma.

         Illinois Power.  Illinois Power Company  ("IPC"),  one of the utilities
with whom SMP has a long-term  uranium supply contract,  unilaterally  sought to
terminate  the  contract on October 28, 1993 and filed suit in the U.S.  Federal
District  Court,  Danville,  Illinois,  against USE,  Crested,  et al. seeking a
declaratory  judgment  that  IPC's  contract  with SMP was void.  After  various
negotiating  sessions the parties  reached  agreement in June 1995 to settle the
case by entering  into an amendment to the original  supply  contract to provide
for 3 deliveries  totaling 486,443 lbs. U3O8. The final delivery was made in May
1997. On June 13, 1997, USE and Crested  received  $838,500 as a distribution of
profits from the final delivery under this SMP contract.

Nevada  naming  USE,  Crested,  Parador  and  H.B.  Layne  Contractor,  Inc.  as
defendants.  The complaint  primarily  concerns extra lateral rights  associated
with two patented lode mining claims (the "Claims")  owned by Parador which were
initially  leased to a predecessor  of BGBI and  subsequently,  the residuals of
that lease were assigned and leased by Parador to USE and Crested.  A bifurcated
trial was held on December  11-12,  1995 before the District Court for the Fifth
Judicial  District  for the State of  Nevada,  County of Nye,  at which time the
parties presented evidence relative to the issue of extra lateral rights.  Other
claims between the parties were bifurcated by the Court and were not at issue at
the trial. On December 26, 1995, the district court issued a ruling denying apex
rights and extra  lateral  royalties to Parador,  USE and  Crested.  The partial
trial did not address the other issues pending in the litigation but limited the
trial to those issues  required to decide the question of extra lateral  rights.
All other  remaining  claims and  counterclaims  were considered by the Court on
January 26-28,  1998 in a bench trial and the Court entered judgment against the
plaintiff and the defendants on their claims.  BGBI,  USECC and Parador appealed
this  judgment  to the Nevada  Supreme  Court.  On June 23,  1998,  a  mandatory
Settlement  Conference was held in Reno, NV but no settlement was achieved.  The
Settlement  Mediator  referred  the  case to the  Nevada  Supreme  Court  for an
expedited hearing and the appeal is currently pending.

         Ticaboo  Townsite  Litigation.  In  fiscal  1998,  the  prior  contract
operator of the  restaurant and lounge and two of its employees who operated the
motel and convenience store at Ticaboo (owned by Canyon  Homesteads,  Inc.) sued
USE, Crested and Plateau Resources Ltd., et al in Utah State Court. After a five
day trial, the jury found against the two plaintiff  employees but found for the
third  plaintiff and a judgment was entered for $153,371 in damages against USE,
which was recorded in fiscal 1998. USE intends to vigorously appeal the award.

         Department of Energy Litigation. On July 20, 1998, eight uranium mining
companies with operations in the United States  (including USE,  Crested,  YSFC)
and the Uranium Producers of America,  a trade  organization,  filed a complaint
against  the  United  States  Department  of Energy  (the  "DOE") and the acting
secretary  in a  lawsuit  (file  no.  98 CV 1775) in the  U.S.  District  Court,
Cheyenne,  Wyoming.  The complaint  seeks  declaratory  judgment and  injunctive
relief.  The plaintiffs allege that the DOE violated the USEC  Privatization Act
of 1996,  when the DOE  transferred  45 metric tons of low enriched  uranium and
3,800  metric  tons of natural  uranium to the United  States  Enrichment  Corp.
("USEC") in May 1998.

         The plaintiffs  have asked the Court among other claims to declare that
(i) the DOE violated its statutory authority by transferring  uranium to USEC in
excess of statutory  limits on volume;  (ii) the excess amounts were not sold by
the DOE to USEC for fair value, as required by the Act, and mandated findings by
the DOE  concerning  possible  adverse  impacts were not supported in fact;  and
(iii) the DOE be enjoined  from future  transfers  in  violation of the Act. The
defendants have not yet responded to the complaint.

Contour Development Litigation

         On July 28,  1998,  USE filed a  lawsuit  in the U.S.  District  Court,
Denver,  Colorado against Contour Development  Company,  L.L.C. and entities and
persons associated with Contour Development Company,

                                   (Continued)

L.L.C. (collectively,  "Contour") seeking compensatory and consequential damages
from the defendants for dealings in certain real estate.

         Specifically,  USE alleges that Contour has breached  contracts for the
sale of the Gunnison  properties  of USE and  Crested,  and is in default on the
contracts and promissory notes delivered to pay for the Gunnison properties.

         As of the filing date of this Report,  Contour and the other defendants
have not filed an answer to the  complaint  but  negotiations  are  underway  to
settle the issues.

Reclamation and Environmental Liabilities

         Most of USE's mine  development,  exploration and operating  activities
are subject to federal  and state  regulations  that  require USE to protect the
environment.  USE attempts to conduct its mining  operations in accordance  with
these regulations, but the rules are continually changing and generally becoming
more  restrictive.  Consequently,  USE's  current  estimates of its  reclamation
obligations and its current level of expenditures to perform ongoing reclamation
may change in the future. At the present time,  however,  USE cannot predict the
outcome  of future  regulation  or its  impact on  costs.  Nonetheless,  USE has
recorded  its best  estimate of future  reclamation  and closure  costs based on
currently available facts, technology and enacted laws and regulations.  Certain
regulatory  agencies,  such as the Nuclear Regulatory  Commission  ("NRC"),  the
Bureau of Land Management  ("BLM") and the Wyoming  Department of  Environmental
Quality ("WDEQ") review USE's  reclamation,  environmental  and  decommissioning
liabilities,  and USE believes its recorded  amounts are  consistent  with those
reviews and related bonding requirements.  To the extent that planned production
on its properties is delayed,  interrupted or discontinued because of regulation
or the  economics  of the  properties,  the  future  earnings  of USE  would  be
adversely affected.  USE believes it has accrued all necessary reclamation costs
and  there  are no  additional  contingent  losses  or  unasserted  claims to be
disclosed or recorded. USE has not disposed of any properties for which it has a
commitment or is liable for any known environmental liabilities.

         The majority of USE's environmental obligations relate to former mining
properties  acquired by USE.  Since USE  currently  does not have  properties in
production,  USE's policy of providing for future  reclamation  and mine closure
costs on a  unit-of-production  basis has not resulted in any significant annual
expenditures  or costs.  For the  obligations  recorded on acquired  properties,
including  site-restoration,  closure and monitoring costs,  actual expenditures
for reclamation  will occur over several years,  and since these  properties are
all considered future production  properties,  those expenditures,  particularly
the closure costs, may not be incurred for many years. USE also does not believe
that any  significant  capital  expenditures  to  monitor  or  reduce  hazardous
substances or other environmental  impacts are currently required.  As a result,
the near term  reclamation  obligations  are not expected to have a  significant
impact on USE's liquidity.

         As of May 31, 1998, USE has recorded estimated reclamation obligations,
including  standby costs,  of $13,055,600  which is included in Reclamation  and
Other Long-term Liabilities in the accompanying  Consolidated Balance Sheets. In
addition,  the GMMV,  in which USE is a 50% owner,  has  recorded a  $23,620,000
liability for future  reclamation and closure costs.  None of these  liabilities
have  been  discounted,  and USE  has  not  recorded  any  potential  offsetting
recoveries from other responsible parties or from any insurance companies.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                   (Continued)

         USE currently has four mineral  properties or investments  that account
for most of its  environmental  obligations,  SMP,  GMMV,  Plateau and SGMC. The
environmental obligations and the nature and extent of cost sharing arrangements
with other potentially  responsible  parties,  as well as any uncertainties with
respect to joint and several  liability of each are  discussed in the  following
paragraphs:

SMP

         USE  and  Crested  are  responsible  for the  reclamation  obligations,
environmental  liabilities  and  liabilities for injuries to employees in mining
operations  with  respect  to  the  Crooks  Gap   properties.   The  reclamation
obligations,  which are established by regulatory authorities,  were reviewed by
USE and the  regulatory  authorities  during  fiscal 1998 and the balance in the
reclamation  liability  account at May 31,  1998 of  $1,451,800  is  believed by
management to be adequate. The obligation will be satisfied over the life of the
mining project which is estimated to be at least 20 years.  USE and Crested self
bonded this  obligation by  mortgaging  certain of its real estate assets and by
holding  certificates of deposits. A portion of the funds for the reclamation of
SMP's  properties  will be provided by a sinking fund of up to $.50 per pound of
uranium for reclamation work as the uranium is produced from the properties.

GMMV

         During  fiscal  1991,  USE  and  Crested  acquired   developed  mineral
properties on Green Mountain known as the Big Eagle Property. In connection with
that  acquisition,  USE and  Crested  agreed  to  assume  reclamation  and other
environmental liabilities associated with the property.  Reclamation obligations
imposed by regulatory  authorities were established at $7,300,000 at the time of
acquisition.  Immediately after the acquisition,  USE and Crested  transferred a
one-half interest to Kennecott, with Kennecott, USE and Crested contributing the
Big  Eagle   properties  to  GMMV,  which  assumed  the  reclamation  and  other
environmental liabilities. Kennecott holds a commercial bank letter of credit as
security for the performance of the  reclamation  obligations for the benefit of
GMMV.

         During  fiscal  1993,  GMMV  entered  into an  agreement to acquire the
Sweetwater uranium mill and related properties from UNOCAL. GMMV's consideration
for the  acquisition of the  Sweetwater  Mill Property was the assumption of all
environmental liabilities and reclamation bonding obligations. The environmental
obligations  of GMMV are  guaranteed by Kennecott.  However,  UNOCAL also agreed
that if GMMV incurs  expenditures  for  environmental  liabilities  prior to the
earlier of commercial  production by GMMV or February 1, 2001 (which liabilities
are not due solely to the  operations of GMMV),  UNOCAL will  reimburse GMMV for
the first $8,000,000 of such expenditures. Any reimbursement may be recovered by
UNOCAL  from 20% of future  cash  flows  from the sale of  uranium  concentrates
processed through the Mill.

         On June 18,  1996,  Kennecott  had a letter of credit in the  amount of
approximately  $19,767,000  issued to the WDEQ for minesite  matters  (executing
EPA-delegated  jurisdiction  to administer the Clean Water Act and the Clean Air
Act, and directly administering Wyoming statutes on mined land reclamation), and
$5,400,000  issued to the NRC for  decontamination  and  cleanup of the Mill and
related tailings cells. An irrevocable letter of credit has been provided by the
Morgan  Guaranty Trust Company of New York in lieu of a surety bond to cover the
reclamation  costs for the minesite and a performance bond by St. Paul Insurance
Company  was  obtained  for the  Mill.  The  letter of credit  was  obtained  by
Kennecott  Uranium Company to cover all reclamation  costs related to mining and
drilling operations in the State of Wyoming. The EPA has

                       U.S. ENERGY CORP. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  MAY 31, 1998
                                   (Continued)

continuing  jurisdiction  under  the  Resource  Conservation  and  Recovery  Act
pertaining  to any  hazardous  materials  which may be on site when cleanup work
commences.

         Although USE and the other GMMV parties are liable for all  reclamation
and environmental compliance costs associated with Mill and site maintenance, as
well as Mill  decontamination and cleanup and site reclamation and cleanup after
the Mill is decommissioned,  USE believes it is unlikely it will have to pay for
such  costs  directly.   First,  based  on  current  estimates  of  cleanup  and
reclamation costs (reviewed annually by the oversight agencies), these costs may
be within the $50,000,000 development commitment and related $16,000,000 loan of
Kennecott Uranium Company for the GMMV. These costs are not expected to increase
materially  if the mill is not put into full  operation.  Second,  to the extent
GMMV is required to spend money on  reclamation  and  environmental  liabilities
related to previous mill and site operations during UNOCAL's  ownership,  UNOCAL
has agreed to fund up to $8,000,000 of costs  (provided these costs are incurred
before  February 1, 2001 and before  Mill  production  resumes),  which would be
recoverable  only out of future mill production (see above).  Third,  payment of
the  GMMV  reclamation  and  environmental  liabilities  related  to the mill is
guaranteed by Kennecott Corporation,  parent of Kennecott Uranium Company. Last,
GMMV will set aside a portion of  operating  revenues  to fund  reclamation  and
environmental liabilities should mining and milling commence.

         Kennecott  will be  entitled  to  contribution  from the USE Parties in
proportion to their participation  interests in GMMV if Kennecott is required to
pay mill cleanup  costs  directly  pursuant to its  guarantee.  Such payments by
Kennecott only would be reimbursed if the liabilities cannot be satisfied within
the  initial  $50,000,000  expenditure  commitment,  and then only to the extent
there are  insufficient  funds from the  reclamation  reserve (to be established
from  GMMV  operating  revenues).  In  addition,  if  and to  the  extent  these
liabilities  resulted  from  UNOCAL's  mill  operations,   and  payment  of  the
liabilities  was  required  before  February 1, 2001 and before mill  production
resumes,  then up to  $8,000,000  of that amount would be paid by UNOCAL  before
Kennecott  Corporation  would be required to pay on its guarantee.  Accordingly,
although the extent of any  ultimate  USE  liability  for  contribution  to mill
cleanup costs cannot be predicted,  USE and Crested will only be required to pay
its proportional share of mill cleanup if a) the liabilities cannot be satisfied
with the initial $50,000,000 expenditure commitment from Kennecott, b) there are
insufficient  funds from the  reclamation  reserve to be established out of GMMV
operating revenues and c) payments are not available from UNOCAL.

Sutter Gold Mining Company

         SGMC is  currently  owned 55% by USE,  4% by Crested and 41% by private
investors.  SGMC owns gold mineral  properties in California.  Currently,  these
properties are in development and costs consist of drilling, permitting, holding
and administrative  costs. No substantial mining has been completed,  although a
2,800 foot decline through the identified ore zones for an underground  mine was
acquired  in  the  purchase.  USE's  policy  is  to  provide  reclamation  on  a
unit-of-production  basis.  Currently,  reclamation obligations are covered by a
$27,000  reclamation bond which SGMC has recorded as a reclamation  liability as
of May 31, 1998.

Plateau Resources, Limited

         The  environmental  and  reclamation   obligations  acquired  with  the
acquisition of Plateau  include  obligations  relating to the  Shootaring  mill.
Based on the bonding  requirements,  Plateau  transferred  $2,500,000 to a trust
account as financial  surety to pay future costs of mill  decommissioning,  site
reclamation and long-term site  surveillance.  In fiscal 1997, Plateau increased
the NRC surety to a cash bond of $6,784,000 in order to have its standby license
changed by the NRC to operational.

YSFC Exchange Rights Agreement

         USE and YSFC  have  entered  into an  Exchange  Rights  Agreement  (the
"Agreement").  Under the Agreement the YSFC private  placement  shareholders and
related broker agent have the right,  but not the obligation,  to exchange their
shares in YSFC for USE common stock if YSFC's  common  shares are not listed and
available  for  quotation  on the NASDAQ  marketing  system by March  1999.  The
exchange rate for USE shares will be the price paid for the YSFC's common shares
plus 10% per annum of total  cost from the date of  purchase.  The number of USE
shares  exchanged  will be based on the exchange  rate for a share of USE common
stock for the five  business  days prior to the date of notice given by the YSFC
shareholder to exchange their shares.

Executive Compensation

         USE and  Crested are  committed  to pay the estates of certain of their
officers an amount equal to one year's salary for one year after their death and
reduced  amounts,  to be set by the Board of Directors,  for a period up to five
years thereafter.

L.       DISCONTINUED OPERATIONS.

         In  February  1996,  USE  completed  the sale of 100% of the  8,267,450
outstanding shares of common stock of Brunton to a third party for $4,300,000 in
accordance with a Stock Purchase Agreement dated January 30, 1996 (the "Purchase
Agreement").  USE received  $300,000 at execution of the Purchase  Agreement and
approximately  $3,000,000  at  closing.  USE  received  two of the three  annual
installments of $333,333 on a $1,000,000 note, plus interest at a rate of 7% per
year during  February 1997 and 1998.  One  additional  payment is due USE in the
amount of $333,333 plus interest in February 1999. In addition,  USE is entitled
to receive 45% of the profits before taxes as defined in the Purchase  Agreement
related to Brunton  products  existing at the time the  Purchase  Agreement  was
executed for a period of 4 years and three months,  beginning  February 1, 1996.
USE received payments of $292,600 for profits in 1997.

         As a result of selling  100% of the common  stock of  Brunton,  USE has
reflected  the  operations  of  Brunton  as  discontinued  in  the  accompanying
financial  statements.  Revenues for the  discontinued  operations  for the year
ended May 31, 1996 was  $2,870,800.  USE  recognized  a gain on the  disposal of
Brunton of $2,295,700 net of income taxes of approximately $50,000.

              Notes to Condensed Consolidated Financial Statements

         1) The Condensed Consolidated Balance Sheet as of November 30, 1998 and
the Condensed Consolidated Statements of Operations for the three and six months
and Cash Flows for the six months  ended  November  30,  1998 and 1997 have been
prepared by USE without audit.  The Condensed  Consolidated  Balance Sheet as of
May 31, 1998, has been taken from the audited financial  statements  included in
USE's Annual Report on Form 10-K for the year then ended. In the opinion of USE,
the accompanying  financial  statements  contain all adjustments  (consisting of
only normal  recurring  accruals)  necessary  to fairly  present  the  financial
position of USE and its  subsidiaries  as of November 30, 1998 and May 31, 1998,
the results of operations  for the three and six months ended  November 30, 1998
and 1997, and the cash flows for the six months then ended.

         2) Certain  information and footnote  disclosures  normally included in
financial  statements  prepared in accordance with generally accepted accounting
principles have been condensed or omitted.  It is suggested that these financial
statements be read in conjunction with USE's May 31, 1998 Form 10-K. The results
of  operations  for the  periods  ended  November  30,  1998  and  1997  are not
necessarily indicative of the operating results for the full year.

         3) The  consolidated  financial  statements  of USE include 100% of the
accounts of USECB Joint Venture  ("USECB" or "USECC")  which is owned 50% by USE
and 50% by USE's subsidiary, Crested Corp. (Crested). The consolidated financial
statements also reflect 100% of the accounts of its majority-owned subsidiaries:
Energx Ltd. (90%),  Crested (52%),  Plateau Resources Limited (100%) Sutter Gold
Mining Co. (59%) and Four Nines Gold,  Inc.  (50.9%) All  material  intercompany
profits and balances have been eliminated.

         4)  Deferred  income at  November  30,  1998 and 1997  consists  of the
$4,000,000 purchase option payment received when USE and its subsidiary, Crested
entered into an Acquisition  Agreement with Kennecott Uranium Company to acquire
properties.  The amount was  forfeitable  until certain actions are taken by USE
and Crested (See GMMV discussion in Item 2).

         5) Accrued reclamation obligations and standby costs of $12,844,200 are
USE's share of a reclamation liability at the SMP mining properties and the full
obligation at the Shootaring Uranium Mill. The reclamation work may be performed
over several years and will not be commenced  until such time as all the uranium
mineralization  contained  in the  properties  is  produced  or  the  properties
abandoned.  It is not  anticipated  that  either of these  events will occur for
sometime into the future.

         6) In February  1997,  SFAS No. 128 "Earnings per Share" was issued and
specifies the computation, presentation and disclosure requirements for earnings
per share.  SFAS 128 is effective for periods ended after  December 15, 1997 and
requires  retroactive  restatement  of prior  period  earnings  per  share.  The
statement  replaces "primary earnings per share" with "basic earnings per share"
and  replaces  "fully  diluted  earnings per share" with  "diluted  earnings per
share." Adoption of SFAS 128 did not have an effect on USE's previously reported
net income (loss) per common share.

         7)  Certain  reclassifications  have  been  made in the  May  31,  1998
financial  statements  to conform to the  classifications  used in November  30,
1998.

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


To Yellow Stone Fuels Corp.:

We have audited the  accompanying  consolidated  balance  sheets of YELLOW STONE
FUELS CORP. (an Ontario  corporation in the development stage) AND SUBSIDIARY as
May 31, 1998 and 1997,  and the related  consolidated  statements of operations,
shareholders'  equity and cash flows for the year ended May 31, 1998 and for the
periods  from  inception  (June 3, 1996)  through May 31,  1997 and 1998.  These
financial  statements are the  responsibility of the Company's  management.  Our
responsibility  is to express an opinion on these financial  statements based on
our audits.

We conducted our audits in  accordance  with United  States  generally  accepted
auditing  standards.  Those standards require that we plan and perform the audit
to obtain reasonable  assurance about whether the financial  statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting  the amounts and  disclosures in the financial  statements.  An audit
also includes assessing the accounting principles used and significant estimates
made by  management,  as well as  evaluating  the  overall  financial  statement
presentation.  We believe  that our audits  provide a  reasonable  basis for our
opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material respects,  the financial position of Yellow Stone Fuels Corp. as of
May 31, 1997 and 1998,  and the results of its operations and its cash flows for
the year ended May 31, 1998 and for the periods  from  inception  (June 3, 1996)
through May 31,  1997 and 1998,  in  conformity  with  United  States  generally
accepted accounting principles.

A.       BUSINESS ORGANIZATION AND DEVELOPMENT STAGE RISKS

Yellow Stone Fuels,  Inc.  ("YSFI") was  incorporated in the State of Wyoming on
June 3, 1996, to engage in the acquisition,  exploration and development  and/or
sale or lease of uranium  properties.  On February 17, 1997,  Yellow Stone Fuels
Corp., (the "Company") was incorporated under the Ontario Business  Corporations
Act. Effective  February 17, 1997, YSFI became a wholly-owned  subsidiary of the
Company  through the  exchange of one share of Yellow  Stone Fuels Corp.  common
shares for each  outstanding  share of YSFI common share  existing at that date.
YSFI continues as a wholly-owned  subsidiary of the Company in order to transact
business in the United States. The accompanying  financial  statements have been
prepared on a basis of  reorganization  accounting (on a continuity of interests
basis) as though  the  Company  had been in  existence  since  inception  of its
wholly-owned  subsidiary on June 3, 1996.  All  references to the Company within
the accompanying  consolidated financial statements and notes collectively refer
to Yellow Stone Fuels Corp.  and YSFI and include  transactions  entered into by
YSFI prior to the February 1997 corporate reorganization.

The  Company  currently  has no  operating  activities,  but is  involved in the
location and acquisition of uranium  properties.  The current target  properties
are those  through  which  uranium  concentrates  (U3O8) can be  produced  using
in-situ leaching methods rather than conventional  mining. The Company currently
holds mineral interests  through patented claims in New Mexico and Wyoming.  The
Company does not currently  anticipate the  construction of a conventional  mill
facility.  If the necessary  permitting can be obtained to operate the mills and
if  contracts  can be arranged  and milling  capacity  is  available,  the final
processing is expected to occur at milling facilities owned by U.S. Energy Corp.
("USE") and Crested  Corp.  ("Crested")  (each 13% and 14%  shareholders  of the
Company as of May 31, 1998 and 1997,  respectively)  and their  affiliates  (see
Note C) .

The Company and USE/Crested  have agreed that should the Company acquire or have
the right to  acquire  any  conventional  uranium  prospect,  it would  first be
offered  to  USE/Crested  with a  reserved  royalty  in  favor  of the  Company.
Conversely,  if  USE/Crested  were to acquire  or have the right to acquire  any
in-situ uranium mining prospect, it would first be offered to the Company with a
reserved  royalty  in favor of  USE/Crested.  USE/Crested  have  also  agreed to
cooperate with the Company in any refining  processes  needed should the Company
engage  in  production  and need  the  benefit  of such  refining  processes  or
regulatory licenses obtained by USE/Crested.

The Company is in the development stage and significant additional  development,
including  development  of well fields on the Company's  uranium  properties and
gathering  systems to remove the U3O8 from mineralized  formations,  is required
prior  to the  commencement  of  commercial  production.  The  Company  has  not
generated  any  revenues  to date and has  incurred a  cumulative  net loss from
inception  (June 3, 1996)  through  May 31,  1998 of  $915,800.  The  Company is
subject  to  various  risks  and  uncertainties  typical  of  development  stage
companies. These risks include, but are not limited to, the following:


                                       137

<PAGE>



As a development  stage  enterprise,  activities to date have primarily been the
acquisition   of   uranium   properties,   obtaining   equity   financing,   and
administrative matters.  Successful future operations are subject to development
stage  risks,  including  the  ability  of the  Company to  successfully  locate
additional uranium properties, mine and market its products and generate revenue
related to the sale of such products  sufficient to support ongoing  operations.
Before revenues and cash flows from operations can be realized, the Company will
require  additional  equity and/or debt financing  which may not be available to
it.

Although the Company believes some of its acquired and leased properties contain
uranium mineralization,  more geological,  geophysical,  engineering,  drilling,
hydrological  and  metallurgical  work remains to be done before an  independent
engineer  could  confirm  the  existence  of ore or  quantify  the extent of ore
reserves and for the  recoverability  of such  reserves on any of the  Company's
prospects. No assurance can be given that any of the Company's prospects contain
ore bodies or are suitable for the  economic  production  of uranium by in- situ
leaching methods.

The  Company's  revenues are expected to be derived  primarily  from the sale of
uranium. Historically, uranium prices have been volatile and will continue to be
affected by numerous  factors beyond the Company's  control,  such as demand for
nuclear  power,  political  and economic  conditions  in uranium  producing  and
consuming countries, production levels and cost of production.  Therefore, there
is no assurance the Company will be able to generate sufficient revenue in order
to achieve successful operations.

Management is currently evaluating different methods to raise the funds required
for further  exploration and  acquisition  activities and the development of its
mineral properties.  There can be no assurance the Company will be successful in
raising sufficient funding for the Company to develop its mineral properties and
begin production.

B.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The  accompanying  consolidated  financial  statements  have  been  prepared  in
accordance with United States  generally  accepted  accounting  principles using
U.S. dollars as the reporting currency.  These financial  statements are also in
accordance  with  Canadian  generally  accepted  accounting  principles  in  all
material aspects.

Use of Estimates

The preparation of financial  statements in conformity  with generally  accepted
accounting principles requires management to make estimates and assumptions that
affect  the  reported  amounts  of  assets  and  liabilities  at the date of the
financial  statements and the reported  amounts of revenues and expenses  during
the reporting period. Actual results could differ from those estimates.

Property and Equipment

The Company  capitalizes all costs related to the acquisition and development of
mineral properties and the acquisition of equipment.  Costs capitalized  through
May 31, 1998 are primarily  acquisition and lease costs.  Capitalized costs will
be amortized using the units of production method once mining commences,  or the
costs will be charged to operations  should the properties be determined to have
declined in value or are abandoned.  Exploration costs are expensed as incurred.
Depreciation of mining equipment  acquired will be provided by the straight-line
method over the  estimated  useful lives of the related  assets when placed into
service.

The Company currently has no operations on its mineral claims in Wyoming and New
Mexico. In addition,  the Company is aware of various title issues, but believes
such issues are of the type often found in connection  with mining  claims,  and
are not material relative to the overall economics of the Company's  properties.
If material  title  problems  arise that affect any of the key  properties,  the
Company could lose one or more of its most important  properties,  or such title
problems could render one or more of the properties uneconomical.

Long-Lived Assets

The  Company  evaluates  its  long-lived  assets for  impairment  when events or
changes in  circumstances  indicate that the related  carrying amount may not be
recoverable.  If the sum of estimated future cash flows on an undiscounted basis
is less than the carrying  amount of the related asset,  an asset  impairment is
considered  to exist.  The related  impairment  loss is  measured  by  comparing
estimated  future cash flows on a discounted basis to the carrying amount of the
asset. Changes in significant  assumptions underlying future cash flow estimates
may have a material  effect on the Company's  financial  position and results of
operations. A low commodity price market, if sustained for an extended period of
time, may result in asset impairment.  As of May 31, 1998,  management  believes
there has not been any impairment of the Company's long-lived assets.

Cash and Cash Equivalents

For  purposes  of  the  statement  of  cash  flows,  cash  equivalents   include
highly-liquid investments with original maturities of three months or less.

Income Taxes

The Company  accounts for income taxes in accordance with Statement of Financial
Accounting Standards No. 109 "Accounting For Income Taxes" ("SFAS No. 109"). See
Note E.

C.       RELATED PARTY TRANSACTIONS

The Company is an  affiliate of USE and its majority  owned  subsidiary  Crested
because of family  relationships  and the substantial  equity ownership of these
entities in the  Company.  USE/Crested  acquired a combined  28% initial  equity
interest in the Company  (3,000,000  common  shares) in exchange  for $60,000 of
technical support,  general and  administrative  services and the utilization of
USE/Crested  personnel  and  equipment.  USE/Crested  have several  conventional
underground   uranium  mining   projects  in  various  stages  of   exploration,
development or pre-production.

USE  and  Crested  provide  certain  management  and   administrative   services
(including  accounting and legal  services,  office space,  rental of equipment,
etc.) to the Company under an Outsourcing  and Lease  Agreement,  which provides
for reimbursement of USE's and Crested's actual costs incurred plus up to 10% of
such actual

                                       139

<PAGE>



costs.  During the year ended May 31,  1998 and for the  period  from  inception
(June 3, 1996) to May 31, 1997,  the Company was charged a total of $684,800 and
$467,400,  respectively,  by USE and  Crested for such  services.  As of May 31,
1998, the Company owed USE and Crested $161,700 under this agreement.

D.       COMMITMENTS AND CONTINGENCIES

As the Company is currently in the development  stage and costs incurred to date
consist primarily of acquisition,  permitting, holding and administrative costs,
no mining has been initiated.  Nevertheless, future reclamation and mine closure
costs  will be the  responsibility  of the  Company  and are  based on legal and
regulatory requirements. These laws and regulations are continually changing and
are generally  becoming more restrictive.  Because the Company has had no mining
operations to date,  it has no  reclamation  obligations  as of May 31, 1998 and
1997.  The Company  will make future  expenditures  as  necessary to comply with
environmental  reclamation laws and regulations and will accrue for the ultimate
reclamation obligations on the units of production method once mining commences.

Lease Agreements

The Company leases its office space under a month-to-month  lease agreement with
USE and Crested.  The current monthly rate is $1,800.  Rent expense for the year
ended May 31, 1998 and for the period from inception  (June 3, 1996) through May
31, 1997 was $18,200 and $10,000, respectively.

Effective October 2, 1996, the Company leases certain of its mineral  properties
from the  State of  Wyoming.  The  leases  expire  on  October  1,  2006 and are
cancelable at the  Company's  option.  The annual rental of these  properties is
$1.00 per acre for the first five years or prior to the  discovery of commercial
quantities of uranium and $2.00  thereafter.  The Company currently leases 3,200
acres.  A royalty  of 5% to 10% of the  gross  value of any  minerals  mined and
removed from the leased lands must be paid to the State of Wyoming.

The Company also leases certain  mineral  properties  located in New Mexico from
Parador  Mining  Co.,  Inc.  ("Parador").  This lease  agreement  requires  rent
payments  of $500 per  month and is  cancelable  at the  option of the  Company.
Royalty  payments of 5% of total gross  proceeds the Company  receives  from the
sale of uranium  obtained  from the leased  mineral  properties  are  payable to
Parador.

E.       INCOME TAXES

Under SFAS 109,  the current  provision  for income taxes  represents  actual or
estimated  amounts payable or refundable on tax returns filed or to be filed for
each year.  Deferred tax assets and  liabilities  are recorded for the estimated
future tax effects of temporary  differences between the tax bases of assets and
liabilities and the financial  reporting bases of assets and liabilities and tax
credit carryforwards.  The overall change in deferred tax assets and liabilities
for the period  measures the deferred tax provision  for the period.  Effects of
changes in enacted tax laws on deferred tax assets and liabilities are reflected
as  adjustments  to tax expense in the period of enactment.  The  measurement of
deferred  tax assets are to be reduced by a valuation  allowance  if, based on a
judgmental  assessment of available evidence,  it is deemed more likely than not
that some or all of the deferred tax assets will not be realized.

To date,  the  Company has  generated  approximately  $884,000 in net  operating
losses for U.S.  Federal  income tax  purposes  and the  Company has no material
temporary  differences  due to the  initial  stage  of its  operations.  The net
operating losses begin expiring in 2012. The Company has established a valuation
allowance  for the entire  amount of deferred tax assets.  The Internal  Revenue
Code contains provisions which may limit the net

                                       140

<PAGE>



operating  loss  carryforwards  available  to be used in any given year upon the
occurrence of certain events, including significant changes in ownership.

F.       NOTE PAYABLE TO AFFILIATE

During May 1997,  the Company  secured a line of credit from USE and Crested for
$400,000,  which represents a restructuring  of the Company's  advances from USE
and Crested.  The facility accrues interest at 10% per annum,  with interest and
principal due on December 31, 1998 and is convertible  into equity under certain
circumstances.  Until  December 31, 1998, the Company may prepay the note at any
time, or convert any outstanding amounts into one share of common stock for each
$1 outstanding, if the Company has either raised an equivalent additional amount
from the sale of equity,  or has realized income from  operations  equal to such
amount.  If the  Company  is unable to repay the note at  maturity,  the note is
convertible  into a number  of  shares  which  will  give USE and  Crested a 51%
interest  in the  Company  when  added to the  shares  already  owned by USE and
Crested.  At May 31,  1998 and 1997,  the  Company  had  $400,000  and  $392,200
outstanding  under this  facility,  respectively.  The Company  owed  $40,000 of
accrued interest on this line of credit as of May 31, 1998.

The Company also had a note payable to a commercial  bank,  bearing  interest at
9.5%,  with a balance of $10,600 as of May 31, 1997.  This note was paid in full
during 1998.

G.       SHAREHOLDERS' EQUITY

Under the Company's  Articles of  Incorporation  and as permitted by the Ontario
Business  Corporation  Act  ("OBCA"),  the Board of Directors of the Company has
authority to create  series of preferred  shares,  and to issue shares  thereof,
without  the  approval  of any  shareholders.  The  creation  and  issue of such
preferred  shares  with  dividend  rights  senior  to the  common  shares  could
adversely  affect common  shareholder  participation  in future earnings through
dividends that otherwise  would be available for  distribution  to the owners of
common  shares.  Such  preferred  shares  also could  inhibit a takeover  of the
Company.  Under the OBCA,  separate  voting  approval  by  classes  of shares is
required for certain  substantive  corporate  transactions.  If the interests of
preferred  shareholders  are perceived to be different  from those of the common
shareholders,   the  preferred  shareholders  could  withhold  approval  of  the
transactions needed to effect the takeover.

During 1997, the Company  completed a private  placement of $1,219,000 shares of
common shares at $2.00 per share.  The Company  received  $2,121,100 of net cash
proceeds  from the private  placement.  In addition to a 13%  commission  on the
shares sold, the broker agent received common share purchase  warrants for up to
121,900  shares  of the  Company's  common  stock at  $2.00  per  share  through
September  2002.  The common  share  purchase  warrants  valued at  $25,500  are
included in common stock in the accompanying balance sheet.
As of May 31, 1998, none of the stock purchase warrants were exercised.

The shares sold are subject to an Exchange Rights  Agreement (the  "Agreement").
Under the Agreement,  the private  placement  shareholders  and the broker agent
have the right, but not the obligation,  to exchange their shares in the Company
for USE common stock if the Company's common shares are not listed and available
for quotation on the NASDAQ  marketing  system by March 1999.  The exchange rate
for USE shares will be the price paid for the Company's common shares,  plus 10%
per annum on such total cost from the date of purchase. The number of USE shares
exchanged will be based on the exchange rate for a share of USE common stock for
the five business days prior to the date of notice given by the  shareholder  to
exchange his or her shares.

Voting Trust Agreement

Pursuant to a Voting Trust  Agreement  dated  September 1, 1997, USE and Crested
agreed,  for a period of 24 months  from the date of the  private  offering,  to
transfer  all  common  shares  beneficially  owned  by the such  parties  to the
Treasurer of USE as Trustee.  The  agreement  instructs  the Trustee to vote all
such common shares at all meetings (or by written action) of the shareholders of
the  Company as  directed  by the Boards of  Directors  of USE and  Crested.  If
direction is not received by the Trustee from the Boards of Directors of USE and
Crested, the agreement provides the Trustee is to vote such common shares in the
Trustee's sole  discretion  for the best interests of USE and Crested.  Assuming
conversion  of the  promissory  note  referenced in Note F, the number of common
shares  subject to the  Voting  Agreements  is  approximately  7,900,000  common
shares.  By amendment  dated September 17, 1997, the Voting Trust Agreement will
become null and void upon either the repayment of the Promissory  Note to USE or
the conversion of such note into common shares of the Company.

H.       STOCK OPTION PLAN

The Company has adopted a Stock Option Plan (the "Plan") under which the Company
has  reserved an  aggregate  of  2,000,000  shares of common  stock for issuance
pursuant to the exercise of options.  Options may be granted to key employees of
the Company, including directors who are also employees of the Company. The Plan
is  administered  by the Board of  Directors  in  accordance  with the rules and
policies of the Toronto Stock  Exchange.  Subject to the terms of the Plan,  the
Board of Directors  determines the persons to whom awards are granted,  the type
of award granted, the number of shares granted,  the vesting schedule,  the type
of  consideration  to be paid to the Company upon  exercise of options,  and the
term of each option (not to exceed five years).  During  February 1997,  600,000
shares  were  granted at an option  price of $1.75 per share with a term of five
years from the date of the grant, of which 20% exercisable at the grant date and
an additional 20% exercisable for each of the four years after the grant date.

During July 1997, the company  granted 50,000 shares at an option price of $1.75
per share with terms  identical to those granted in February  1997.  The company
recognized  $12,500 of  compensation  expense during fiscal 1998 related to this
grant.

Statement of Financial Accounting Standards No. 123 ("SFAS 123")

SFAS 123, "Accounting for Stock-Based  Compensation," defines a fair value based
method of accounting for employee  stock options or similar equity  instruments.
However, SFAS 123 allows the continued measurement of compensation cost for such
plans using the intrinsic  value based method  prescribed by APB Opinion No. 25,
"Accounting for Stock Issued to Employees"  ("APB 25"),  provided that pro forma
disclosures  are made of net  income or loss and net  income or loss per  share,
assuming the fair value based method of SFAS 123 had been  applied.  The Company
has  elected to account  for its  stock-based  compensation  plans under APB 25.
Accordingly, for purposes of the pro forma disclosures required by SFAS 123, the
Company has computed the fair values of all options  granted  during fiscal year
1998 and 1997 using the Black-Scholes  pricing model and the following  weighted
average assumptions:

J.       RECENTLY ISSUED OR ADOPTED ACCOUNTING STANDARDS

In  February  1998,  Statement  of  Position  98-5,  "Reporting  on the Costs of
Start-Up  Activities"  ("SOP  98-5") was issued which  provides  guidance on the
financial  reporting of start-up and organizational  costs. It requires costs of
start-up  activities  and  organization  costs to be expensed as  incurred.  The
Company will adopt SOP 98-5 during fiscal 1999.  As of May 31, 1998,  management
does not believe SOP 98-5 will have a material  impact on the Company's  results
of operations or financial position.

In February 1997,  Statement of Financial Accounting Standards No. 128 "Earnings
per Share", ("SFAS 128") was issued and specifies the computation,  presentation
and disclosure  requirements  for earnings per share.  SFAS 128 is effective for
periods ended after  December 15, 1997 and requires  retroactive  restatement of
prior period earnings per share. The statement  replaces  "primary  earnings per
share" with "basic earnings per share" and replaces "fully diluted  earnings per
share" with "diluted  earnings per share."  Adoption of SFAS 128 did not have an
effect on the  Company's  previously  reported  net loss per common  share.  The
following  table  presents a  reconciliation  of basic and diluted  earnings per
share calculations:

</TABLE>

Because a substantial majority of shares outstanding at May 31, 1997 are held by
affiliates  and  related  parties,  all  shares  are  considered  to  have  been
outstanding since inception.  Because of the net loss reported in 1998 and 1997,
all common share  purchase  warrants and stock  options were  excluded  from the
calculation of diluted net loss per share as their effect is antidilutive.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                NOVEMBER 30, 1998

         1) The Balance  Sheet as of November  30,  1998,  and the  Statement of
Operations  and Cash Flows for the six months ended  November 30, 1998 and 1997,
have been prepared by YSFC without audit. The Balance Sheet at may 31, 1998, has
been taken from the audited  financial  statements.  In the opinion of YSFC, the
accompanying  financial  statements contain all adjustments  (consisting of only
normal recurring accruals) necessary to fairly present the financial position of
YSFC and its affiliate as of November 30, 1998 and May 31, 1997,  the results of
operations  for the three and six months ended  November 30, 1998 and 1997,  and
the cash flows for the six months ended.

         2) Certain  information and footnote  disclosures  normally included in
financial  statements  prepared in accordance with generally accepted accounting
principles have been condensed or omitted.  It is suggested that these financial
statements be read in conjunction with YSFC's May 31, 1998 financial statements.
The results of operations  for the periods ended  November 30, 1998 and 1997 are
not necessarily indicative of the operating results for the full year.

         3) Debt at May 31, 1998 and November 30, 1998 consists primarily of the
balance on a note payable to YSFC's affiliate USE of $400,000 plus interest.

         4) In February  1997,  SFAS No. 128 "Earnings per Share" was issued and
specifies the computation, presentation and disclosure requirements for earnings
per share.  SFAS 128 is effective for periods ended after  December 15, 1997 and
requires  retroactive  restatement  of prior  period  earnings  per  share.  The
statement  replaces "primary earnings per share" with "basic earnings per share"
and  replaces  "fully  diluted  earnings  per share" with  diluted  earnings per
share."  Adoption  of SFAS  128 did not  have an  effect  on  YSFC's  previously
reported net income (loss) per common share.

         5)  Certain  reclassifications  have  been  made in the  May  31,  1998
financial  statements  to conform to the  classifications  used in November  30,
1998.

                        Report of Independent Accountants


To the Members of the Management Committee of
Green Mountain Mining Venture
Riverton, Wyoming

We have audited the accompanying  balance sheet of Green Mountain Mining Venture
(A Joint Venture in the Development Stage) as of December 31, 1997 and 1996, and
the related statements of operations,  changes in Venture partners' capital, and
cash flows for the years ended December 31, 1997,  1996 and 1995, and the period
from inception (June 1, 1990) to December 31, 1997.  These financial  statements
are the  responsibility of the Venture's  management.  Our  responsibility is to
express an opinion on these financial statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material  respects,  the financial position of Green Mountain Mining Venture
as of December 31, 1997 and 1996, and the results of its operations and its cash
flows for the years ended December 31, 1997,  1996 and 1995, and the period from
inception  (June 1, 1990) to December 31, 1997,  in  conformity  with  generally
accepted accounting principles.

                          NOTES TO FINANCIAL STATEMENTS
                                     ------

1.       Organization of the Joint Venture:

         Green  Mountain  Mining  Venture  ("GMMV" or the  "Venture") is a joint
         venture  with a 30 year  life,  formed by U.S.  Energy  Corp.  ("USE"),
         Crested Corp.  ("Crested") and Kennecott Uranium Company ("Kennecott"),
         the Venture  partners,  to explore  for,  evaluate,  develop,  mine and
         market the mineral resources from the Green Mountain properties located
         in south-central Wyoming. Kennecott has a 50% interest in GMMV, and USE
         and Crested ("USECC") collectively have a 50% interest. GMMV was formed
         June 1, 1990, with each partner  contributing  its portion of the Green
         Mountain  properties.  Kennecott  acquired  its  portion  of the  Green
         Mountain  properties  from  USECC  in 1990  for a cash  payment  of $15
         million.  Thereafter,  the partners are  required to  contribute  funds
         based upon their respective participating interests, subject to certain
         provisions as provided for in the joint venture agreement.

         Kennecott has agreed to  contribute  the first $50 million of operating
         and  development  expenses  pursuant to Management  Committee  budgets.
         Kennecott  also  agreed  to  pay a  disproportionate  share  (up  to an
         additional  $45 million) of GMMV  operating  expenses,  but only out of
         cash  operating  margins from sales of  processed  uranium at more than
         $24.00/lb (for $30 million of such operating expenses),  and from sales
         of processed  uranium at more than  $27.00/lb (for the next $15 million
         of such operating expenses).

         Effective October 29, 1992,  Kennecott replaced USECC as manager of the
         Venture.  Kennecott  contracts  with USECC to perform work on behalf of
         the Venture.

         On June 23, 1997,  Kennecott and USECC signed an Acquisition  Agreement
         wherein USECC agreed to purchase  Kennecott's  interest in GMMV for $15
         million plus the assumption of Kennecott's share of various reclamation
         and other  liabilities.  Kennecott  paid $4 million to USECC on signing
         the  Acquisition  Agreement  and  under  the  terms of the  Acquisition
         Agreement  is  required  to  contribute  up to $16  million to GMMV for
         payment of costs related to the Jackpot mine development and Sweetwater
         mill preparation work.  Amounts advanced under this line of credit bear
         interest at 10.5% with repayment  based upon the cash flow and earnings
         of GMMV.  Any unpaid  balance is payable in full no later than June 23,
         2010 as long as USECC or its affiliate purchases  Kennecott's  interest
         in the GMMV. The line of credit is  collateralized  by a first mortgage
         lien  against   Kennecott's  50%  interest  in  GMMV.  Closing  of  the
         Acquisition Agreement is subject to several conditions and governmental
         approvals  and must occur by October  1998.  Kennecott is entitled to a
         credit against their original $50 million commitment of two dollars for
         each dollar  provided  under the line of credit and the $4 million paid
         on signing. As of December 31, 1997,  Kennecott has approximately $10.8
         million  remaining  to  contribute  to the  Venture for  operating  and
         development expenses.

                    NOTES TO FINANCIAL STATEMENTS, Continued

1.       Organization of the Joint Venture, Continued:

         Through December 31, 1997, the activities of the Venture have consisted
         primarily of the  development  and  maintenance  of the Green  Mountain
         properties.  While  these  activities  are  expected to continue in the
         future, additional development at substantially higher annual levels is
         required  prior to the  commencement  of  commercial  production.  Such
         commencement is not expected to occur until the venture  partners agree
         that all  economic  and other  conditions  justify  such  commencement.
         Therefore,  the Venture is considered to be in the development stage as
         defined in Statement of Financial Accounting Standards No. 7.

2.       Summary of Significant Accounting Policies:

         All highly  liquid  securities  with a maturity of three months or less
         are considered to be cash equivalents.

         Mineral  properties  contributed  to the Venture  were  recorded at the
         partners'  historical cost at the date of contribution.  Costs incurred
         in the  acquisition of mineral  properties are  capitalized and will be
         either charged to operations on the units-of-production method over the
         estimated reserves to be recovered or charged to operations at the time
         the property is sold or  abandoned.  Mine  development  costs  incurred
         either to expand the  capacity  of  operating  mines,  develop  new ore
         bodies or develop mine areas substantially in advance of production are
         capitalized    and   will   be   charged   to    operations    on   the
         units-of-production method over the estimated reserves to be recovered.
         Amortization of mineral  properties and development costs will commence
         when  mining  operations  start.  Mine  development  costs  incurred to
         maintain production are included in operating costs and expenses.
         Maintenance and holding costs are expensed as incurred.

         The cost of mining  equipment,  less estimated  salvage value,  will be
         depreciated  on the  units-of-  production  method  over the  estimated
         reserves  to be  recovered  or on the  straight-line  method  over  the
         estimated  life of the  equipment,  whichever  is shorter.  The cost of
         buildings will be depreciated on the straight-line method. Depreciation
         of mining equipment and buildings will commence when mining  operations
         start.  Costs of repairs and  maintenance  are  expensed  as  incurred.
         Expenditures that  substantially  extend the useful lives of assets are
         capitalized.  When assets are  retired or  otherwise  disposed  of, all
         applicable  costs and  accumulated  depreciation  are removed  from the
         accounts and any resulting gain or loss is recognized currently.

2.       Summary of Significant Accounting Policies, Continued:

         The Venture evaluates the recoverability of capitalized acquisition and
         development  costs  based  on  the  expected  undiscounted  future  net
         revenues from the related mining properties. An impairment loss will be
         recorded if the  unamortized  costs  exceed the  expected  undiscounted
         future net revenues.  The recorded loss will be based on the difference
         between the unamortized  costs and the expected  discounted  future net
         revenues from the related mining properties.  The Venture believes that
         uranium prices will reach levels sufficient to justify  commencement of
         commercial  production  in the future.  The Venture  also  believes the
         expected  undiscounted  future  net  revenues  from the Green  Mountain
         properties  will  be  sufficient  to  allow   recoverability  of  these
         capitalized costs, assuming commencement of commercial production.

         The estimated net future costs of dismantling, restoring and reclaiming
         operating  mines which  result from future  mining  operations  will be
         accrued  during such  operations.  The provision will be made using the
         units-of-production  method over the estimated reserves to be recovered
         and estimated costs at the balance sheet date. The effect of changes in
         estimated  costs and  production  will be  recognized  on a prospective
         basis.

         No provision  has been made for federal,  state and local income taxes,
         credits,  or benefits since tax liabilities are the  responsibility  of
         the individual partners.

         The  preparation of financial  statements in conformity  with generally
         accepted  accounting  principles  requires management to make estimates
         and  assumptions  that  affect  the  reported  amounts  of  assets  and
         liabilities and disclosure of contingent  assets and liabilities at the
         date of the financial  statements and the reported  amounts of revenues
         and expenses during the reporting  period.  Actual results could differ
         from those estimates.

         Certain amounts in 1996 have been  reclassified  for  comparability  to
         1997 amounts.

3.       Property and Equipment:

         USECC  conducts  operations  at the mine site on behalf of the Venture.
         All  accounts  payable are due to USECC for costs  incurred by USECC in
         the normal course of business on behalf of GMMV.  Through  December 31,
         1997 Kennecott had reimbursed USECC for  substantially  all development
         costs incurred.

         The cost of  building,  mineral  properties  and mine  development  and
         mining  equipment  incurred  by each  of the  Venture  partners  are as
         follows:

         In December  1990,  GMMV  acquired  additional  mineral  properties  in
         exchange for the assumption of reclamation  liabilities associated with
         those properties of $7.3 million. In 1992, GMMV acquired an established
         uranium  processing  mill (the  Sweetwater  Mill) in  exchange  for the
         assumption of reclamation  liabilities associated with this property of
         $16.3  million.  Such  amounts  represent  the  estimated  costs at the
         acquisition  date to  reclaim  these  properties.  Kennecott  holds  an
         irrevocable  letter of credit through Morgan Guaranty Trust of New York
         in the amount of  $19,767,079  in favor of the  Wyoming  Department  of
         Environmental   Quality  ("WDEQ")  and  the  U.S.  Nuclear   Regulatory
         Commission  in the  event  GMMV  does not  properly  reclaim  the above
         properties or violates the Wyoming  Environmental  Quality Act.  Before
         the earlier of January 1, 2001,  or resumption  of  production,  if the
         GMMV is required  to incur  reclamation  or  environmental  costs,  the
         seller  of the mill will be liable  for the first $8  million  of these
         costs at the Sweetwater Mill.

         The Venture  properties  include  state leases which will expire in May
         2001 and  October  2006.  All fees  required  to hold these  unpatented
         mining claims have been paid to the state of Wyoming as of December 31,
         1997.

3.       Property and Equipment, Continued:

         At  December  31, 1997 and 1996,  costs  capitalized  as  property  and
         equipment are composed of the following:

                                           1997                  1996

             Development costs          13,596,261              8,683,086
                                      ------------           ------------

                                      $ 52,943,261           $ 48,030,086
                                      ============           ============

         Acquisition costs include the partners' initial contribution of mineral
         properties  and  buildings  recorded  at  the  contributing   partners'
         historical  cost of  $15,727,000  and mineral  properties and buildings
         acquired in exchange  for the  assumption  of  reclamation  liabilities
         totaling $23,620,000.

4.       Contingencies:

         In June 1994, Kennecott was served with a complaint filed by Nukem Inc.
         (Nukem)  and  Cycle  Resource  Investment   Corporation   (Cycle).  The
         complaint  alleged that when Kennecott  entered into the Green Mountain
         Mining Venture with USE on June 1, 1990,  Kennecott  interfered  with a
         Uranium  Marketing  Agreement (UMA) between Nukem and USE and the Sheep
         Mountain Partners  Partnership  Agreement (SMPA) between USE and Cycle.
         Nukem and Cycle were each seeking  damages in excess of $14 million and
         punitive damages.

         The case was stayed pending the conclusion of an arbitration proceeding
         between Cycle,  Nukem and USE. The arbitration  panel entered its order
         in April 1996,  and the stay in this case was lifted.  The  arbitration
         panel held against Nukem in material respects stating that, even if the
         UMA had been  breached,  Nukem suffered no damages  thereby.  The panel
         denied the relief  that Cycle  sought for  alleged  breach of the SMPA.
         Accordingly,  on January 6, 1997,  Kennecott filed a motion for summary
         judgment contending,  among other things, that the arbitration findings
         collaterally  estop all claims  asserted by Nukem and Cycle.  On August
         22,  1997 the  trial  court  granted  Kennecott's  motion  for  summary
         judgement and  dismissed  the claims of Nukem and Cycle.  Following the
         motion,  the parties  agreed to settle the case, and in February 1998 a
         settlement agreement was signed which resulted in both parties agreeing
         to suspend all litigation and claims against each other.

5.       Subsequent Events:

         In 1996, the U.S.  government  adopted the "USEC  Privatization  Act of
         1996" to privatize  the U.S.  Enrichment  Corp.  In July 1998, in a S-1
         Registration   Statement  filed  with  U.S.   Securities  and  Exchange
         Commission,  USEC  Inc.  disclosed  its  planned  sale  of  significant
         quantities of uranium in the U.S. marketplace.  Accordingly, forecasted
         demand for uranium and  forecasted  uranium sales prices have decreased
         in the short-term.  As a result, GMMV has halted development activities
         at the Jackpot Mine, and has placed the facility on active standby.

         On October  30,  1998,  the  Acquisition  Agreement  between  USECC and
         Kennecott was  terminated due to  difficulties  experienced by USECC in
         raising the financing  needed to complete the Agreement.  Subsequent to
         December 31, 1997,  Kennecott fully impaired its investment in the GMMV
         due to the continued  softness in the uranium  oxide  market.  However,
         because  of its  commitments  under  the  GMMV  permits  and  licenses,
         Kennecott will continue to fund its share of GMMV expenses.

Item 20.  Indemnification of Directors and Officers.

The Wyoming Business Corporation Act ("WBCA"),  W.S. 17-16-850 et seq., provides
for indemnification of USE's officers, directors,  employees, and agents against
liabilities  which  they  may  incur  in such  capacities.  A  summarization  of
circumstances in which such  indemnification  may be available  follows,  but is
qualified by reference to registrant's Articles of Incorporation and the text of
the statute.

In general, any officer, director, employee, or agent may be indemnified against
expenses,  fines,  settlements,  or judgments arising in connection with a legal
proceeding to which such person is a party, as a result of such relationship, if
that person's  actions were in good faith,  were believed by him or her to be in
(or at least not opposed to) registrant's best interests, and in the case of any
criminal  proceeding,  he or she had no  reasonable  cause to believe his or her
conduct was unlawful.  Unless such person is successful  upon the merits in such
an action, indemnification may be awarded only after a determination by decision
of  the  board  of  directors  (by  directors  not at the  time  parties  to the
proceeding) or by majority shareholder vote (excluding shares held or controlled
by directors  who are at the time parties to the  proceeding),  or by opinion of
special legal counsel.

The circumstances under which  indemnification  would be made in connection with
an action  brought on behalf of the  registrant are generally the same as stated
above, except that indemnification is permitted only for reasonable expenses.

In addition, registrant has statutory authority to purchase insurance to protect
its officers, directors,  employees, and agents against any liabilities asserted
against them, or incurred in connection  with their service in such  capacities.
Further,  registrant may advance or reimburse funds to a director who is a party
to  a  proceeding,  for  reasonable  expenses  incurred  in  connection  with  a
proceeding.

Item 22.  Undertakings.

(a)    Pursuant to Item 512 of Regulation S-K, the registrant hereby undertakes:

(a)(1) To file,  during any period in which  offers or  sales are being  made, a
post-effective amendment to this registration statement:

         (i)  To include any  prospectus  required  by  section 10(a)(3) of the
Securities Act of 1933;

         (ii) To reflect in the prospectus any facts or events arising after the
effective date of the registration  statement (or the most recent post-effective
amendment  thereof)  which,  individually  or  in  the  aggregate,  represent  a
fundamental change in the information set forth in the registration statement;

         (iii) To include any material  information  with respect to the plan of
distribution  not  previously  disclosed  in the  registration  statement or any
material change to such information in the registration statement.

(a)(2) That, for the purpose of determining  any liability  under the Securities
Act of 1933,  each  such  post-effective  amendment  shall be deemed to be a new
registration  statement  relating to the  securities  offered  therein,  and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

(a)(3) To remove from registration by means of a post-effective amendment any of
the securities  being  registered which remain unsold at the termination of this
offering.

(b) Pursuant to Item 22(b) of Form S-4, the registrant  undertakes to respond to
requests for  information  that is incorporated by reference into the prospectus
pursuant to Items 4, 10(b),  11, or 13 of this Form S-4 within one  business day
of receipt of such  request,  and to send the  incorporated  documents  by first
class mail or other equally prompt means. This includes information contained in
documents filed subsequent to the effective date of the  registration  Statement
through the date of responding to the request.

(c) Pursuant to Item 22(c) of Form S-4, the  registrant  undertakes to supply by
means of a post-effective amendment all information concerning a transaction and
the company being  acquired  involved  therein,  that was not the subject of and
included in the registration statement when it became effective.

(g)(1)  That  prior  to  any  public  reoffering  of the  securities  registered
hereunder  through  use of a  prospectus  which  is a part of this  registration
statement,  by any person or party who is deemed to be an underwriter within the
meaning  of  Rule  145(c),  the  registrant   undertakes  that  such  reoffering
prospectus   will  contain  the   information   called  for  by  the  applicable
registration  form with  respect to  reofferings  by  persons  who may be deemed
underwriters,  in addition to the  information  called for by the other items of
the applicable form.

(g)(2)  That  every  prospectus  (i) that is filed  pursuant  to  paragraph  (1)
immediately preceding, or (ii) that purports to meet the requirements of section
10(a)(3) of the Act and is used in  connection  with an  offering of  securities
subject to Rule 415, will be filed as a part of an amendment to the registration
statement and will not be used until such amendment is effective,  and that, for
purposes of determining  any liability  under the Act, each such  post-effective
amendment  shall be deemed to be a new  registration  statement  relating to the
securities  offered  therein,  and the offering of such  securities at that time
shall be deemed to be the initial bona fide offering thereof.


                                       167

(h) Insofar as indemnification  for liabilities arising under the Securities Act
of 1933, may be permitted to directors, officers, and controlling persons of the
registrant,  the  registrant  has  been  advised  that  in  the  opinion  of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Act, and is, therefore,  unenforceable.  In the event that a
claim for  indemnification  against such liabilities  (other than the payment by
the  registrant  of  expenses  incurred  or  paid  by a  director,  officer,  or
controlling  person of the  registrant in the  successful  defense of any action
suit or proceeding) is asserted by such officer, director, or controlling person
in connection with the securities being registered,  the registrant will, unless
in the  opinion  of its  counsel  the matter  has been  settled  by  controlling
precedent, submit to a court of appropriate jurisdiction the question of whether
such  indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

                            EXCHANGE RIGHTS AGREEMENT


         This Exchange Rights Agreement (the  "Agreement") is entered into as of
September 17, 1997 by and between Yellow Stone Fuels  Corporation  ("YSFC"),  an
Ontario,  Canada  corporation  with  offices  at 877 North  8th West,  Riverton,
Wyoming 82501, U.S. Energy Corp.  ("USE"), a Wyoming corporation with offices at
877 North 8th West,  Riverton,  Wyoming 82501,  and R A F Financial  Corporation
("RAF"), a corporation with offices at 1700 Lincoln Street, 32nd Floor,  Denver,
Colorado 80203.

                                    RECITALS

         Whereas, USE and its affiliated corporation, Crested Corp. ("Crested"),
own shares of Common Stock of YSFC and have the right to convert indebtedness to
additional shares of Common Stock of YSFC; and

         Whereas,  USE has taken the initiative in founding and organizing  YSFC
and may be deemed to be a founder and promoter of YSFC; and

         Whereas, YSFC has or will enter into an Selling Agent Agreement ("Agent
Agreement") with RAF under which RAF has agreed to or will agree to use its best
efforts,  as agent for YSFC,  to place (sell) shares of Common Stock of YSFC for
YSFC in a private  offering (the "Private  Offering")  for up to US$3 million in
gross  proceeds;  provided  that,  YSFC and RAF prior to the end of the  Private
Offering may mutually agree to increase the size of the Private Offering up to a
maximum of US$5 million in gross proceeds. Hereafter, the shares of Common Stock
which will be sold in the  Private  Offering  are  referred  to as the  "Private
Offering  Shares" and the information  about YSFC and the Private Offering to be
delivered to the purchasers ("Investors") in the Private Offering is referred to
as the "Private Placement Memorandum"; and

         Whereas,  RAF will receive,  as a part of its  compensation for sale of
the  Private  Offering  Shares,  Warrants  to  Purchase  Common  Shares  of YSFC
("Agent's  Warrants",  and the  future  holders  of such  Agent's  Warrants  are
referred to as the "Warrantholders"); and

         Whereas,  the offer and sale of the Private Offering Shares will not be
registered  with the  Securities  and Exchange  Commission  ("SEC")  pursuant to
Section 5 of the  Securities  Act of 1933 ("1933  Act") or any state  securities
laws and,  therefore,  the Private  Offering Shares will constitute  "restricted
securities" under SEC Rule 144 and state securities laws; and

         Whereas,  USE, YSFC and RAF have  negotiated  the terms and  conditions
under which the  Investors  and their  assignees  will have the  opportunity  to
exchange all or a part of their Private  Offering  Shares for USE Shares if YSFC
is not listed on, and the Common Stock of YSFC is not  available  for  quotation
on, the Nasdaq National Market System ("NNM") by the eighteen month  anniversary
of the date of the Private Placement Memorandum (the "Listing Period"); and

         Whereas,  USE, YSFC and RAF have  negotiated  the terms and  conditions
under which the  Warrantholders and the holders of Common Stock of YSFC acquired
upon the  exercise of the Agent's  Warrants  ("Exercise  Shares")  will have the
opportunity  to  exchange  all or a part of their  Agent's  Warrants or Exercise
Shares for USE Warrants or for USE Shares,  respectively,  if YSFC is not listed
on, and the Common Stock of YSFC is not  available  for quotation on, NNM during
the Listing Period; and

         Whereas, the Common Stock of USE is listed on NNM.

         Shares owned by an Investor or an Investor's  assignee at the beginning
         of the Exchange Period; provided, that USE will only recognize and this
         Agreement  only shall be  enforceable  with  respect  to an  Investor's
         assignee  of an  Investor's  Exchange  Shares  if  (i)  the  Investor's

         compliance  with the 1933 Act and such compliance is established to the

         the Investor's  purchase of the Private  Offering Shares in the Private
         Offering and ending on the Exchange Date.

                  "USE Shares"  shall mean shares of Common Stock of USE,  $0.01

                           transaction  which  changes  the  kind  or  number of
                           shares of Common Stock of YSFC or USE, then  full and
                           equitable adjustment in the number of USE  Shares and
                           USE  Warrants  shall  be  made with  the objective of
                           maintaining after the transaction the relative values
                           of the  Investor's  Exchange  Value and the USE Share
                           Value  before  such  stock  dividend or other capital
                           reorganization  or  other  transaction  as  if  such
                           transaction  had  not  occurred,  taking into account
                           changes  in  USE  Share  Value  which  have  resulted
                           otherwise  than  from  such  stock  dividend or stock
                           split, etc.

         USE and YSFC agree that from the date of this  Agreement  until the day
after the last day of the Exchange, neither USE nor YSFC will take or permit any
action,  including,  but not  limited  to, a merger,  reorganization  or sale of
assets,  which  would  terminate  or  diminish  the  rights  of  the  Investors,
Investors'  assignees,  Warrantholders  or holders of Exercise Shares under this
Agreement.

                  vi.      Injunctive Relief. USE irrevocably grants RAF and its
                           assignees,   in  addition  to  other  legal  remedies
                           available,  the  right  to apply  for an  injunction,
                           without  bond   exceeding   $500,  to  enforce  USE's
                           covenants  herein and USE's sole  remedy in the event
                           of the entry of such  injunctive  relief shall be the
                           dissolution of such injunctive  relief, if warranted,

                           being expressly waived hereby).
