                            profitably separated;

POSSIBLE GEOLOGICAL
RESOURCES                   A mineral resource inferred from geoscientific
                            evidence, drill holes, underground openings or
                            other sampling procedures where the lack of data is
                            such that continuity cannot be predicted with
                            confidence and where geoscientific data may not be

                            with a reasonable level of reliability. A probable
                            geological resource estimate will be based on more
                            data, and therefore will be more reliable, than a

                            drilling, sampling or excavation (including
                            extensions beyond actual openings and drill holes),
                            and where the geological factors that control the
                            ore body are known with sufficient confidence that
                            the geological reserve is categorized as
                            "Indicated";

                            sampling procedures at locations which are spaced
                            closely enough to confirm continuity and where
                            geoscientific data are reliably known. A proven
                            geological resource estimate will be based on a
                            substantial amount of reliable data, interpretation
                            and evaluation of which allows a clear
                            determination to be made of shapes, sizes,
                            densities and grades;

PROVEN MINEABLE RESERVES    Ore reserves stated in terms of mineable tons or
                            volumes and grades in which the corresponding
                            identified geological reserve has been defined in
                            three dimensions by excavation or drilling
                            (including minor extensions beyond actual openings
                            and drill holes), and where the geological factors
                            that limit the ore body are known with sufficient
                            confidence that the geological reserve is
                            categorized as "Measured";

                                     PART I

ITEM 1 - DESCRIPTION OF BUSINESS

International Uranium Corporation (the "Registrant") is the product of an
amalgamation under the Business Corporations Act (Ontario) (the "Act") of two
companies; namely, International Uranium Corporation, incorporated on October
3, 1996 under the laws of the Province of Ontario pursuant to the Act, and
Thornbury Capital Corporation, incorporated under the laws of the Province of
Ontario by Letters Patent ("Thornbury") on September 29, 1950.  The
amalgamation was made effective on May 9, 1997, pursuant to a Certificate of
Amalgamation dated that date.  The amalgamated companies were continued under
the name "International Uranium Corporation" (see "Amalgamation").





                                       4

The head office of the Registrant is located at Independence Plaza, Suite 950,
1050 Seventeenth Street, Denver, CO 80265. The registered office of the
Corporation is located at Suite 2100, Scotia Plaza, 40 King Street West,
Toronto, Ontario, M5H 3C2.

The Registrant is engaged in the business of producing uranium concentrates and
in the selling and trading of these concentrates in the international nuclear
fuel market. As a co-product of its uranium production, the Registrant also
produces and sells vanadium.

The Registrant entered the uranium industry in May 1997 by acquiring
substantially all of the uranium producing assets of Energy Fuels Ltd., Energy
Fuels Exploration Company, and Energy Fuels Nuclear, Inc. (collectively "Energy
Fuels"). The Registrant raised Cdn$47.25 million through a special warrant
private placement and used cash of approximately Cdn$29.3 million to purchase
the Energy Fuels' assets (see "Acquisition" for further details).  Energy Fuels
was a uranium producer with properties in the United States and Mongolia.

The Energy Fuels' assets acquired included several developed mines on standby,
several partially developed mines, numerous targeted mines and exploration
properties within the states of Colorado, Utah, Arizona, Wyoming and South
Dakota, as well as the 2,000 ton per day White Mesa Mill near Blanding, Utah.
The White Mesa Mill is a fully permitted dual circuit uranium/vanadium mill in
the United States that has been operating over the last 10 years.  Since its
start-up in 1980, the White Mesa Mill, which also has a vanadium and other co-
product recovery circuit, has produced over 27 million pounds of uranium and
over 43 million pounds of vanadium in six separate milling campaigns.  As a
result of the acquisition, the Registrant's U.S. properties comprise over
50,000 acres and contain proven and probable geological resources of 42 million
pounds of uranium and 62 million pounds of vanadium in the U.S..  Potential
additional geological resources are estimated to be 58 million pounds of
uranium and 29 million pounds of vanadium.  In addition to the U.S. properties,
the Registrant also acquired a 70% interest in a joint venture with the
government of Mongolia and a Russian geological concern to develop and produce
uranium reserves in Mongolia.   The Mongolian concessions encompass
approximately 4,000,000 acres with an estimated potential uranium geological

International Uranium (Bermuda I) Ltd. and International Uranium Company
(Mongolia) Ltd., were incorporated solely for the purposes of holding shares of
Gurvan Saihan Joint Venture Corp.  In the event the Registrant expands its
operations to include additional assets or assets in other countries, it is
possible that these assets may also be held through one or more additional
offshore entities, some of the shares of which may be held by International
Uranium (Bermuda I) Ltd.

The White Mesa Mill is held by IUC White Mesa LLC (see "White Mesa Mill"), the
exploration properties are held by IUC Exploration LLC, the Sunday Mine Complex
is held by IUC Sunday Mine LLC (see "Sunday Mine Complex"), the remainder of
the Colorado Plateau mines are held by IUC Colorado Plateau LLC (see "Colorado
Plateau"), the Reno Creek Property is held by IUC Reno Creek LLC (See Reno
Creek Property"), the Arizona Strip mines are held by IUC Arizona Strip LLC
(see "Arizona Strip") and the mines that are in reclamation are held by IUC
Properties LLC, each of which is a limited liability company under the laws of
Colorado.  International Uranium (USA) Corporation is the operating company
that is responsible for operations in the United States and Mongolia. It does
not hold assets of any significance other than permits and licenses, and the
head office administrative assets. The operational management team for the
United States and Mongolia and the employees of the United States operations
are employed by International Uranium (USA) Corporation.  Most of the remaining
assets purchased from Energy Fuels are held directly by International Uranium
Holdings Corporation.

International Uranium U.S. Finance LLC ("Finance") is a limited liability
company, which was originally formed to provide financing to International
Uranium Holdings Corporation ("Holdings") and its subsidiaries, as required.
All financing previously provided by Finance to Holdings and its subsidiaries
has been repaid and Finance has been merged into Holdings.   As consideration
in the merger,  Holdings issued preferred stock  to the Registrant in the face
amount of $1.5 million.

The Registrant's principal strategy is to maintain and build upon its position
as a producer of uranium concentrates to the international nuclear fuel market.
The Registrant will also continue to produce and sell vanadium as a co-product
of its uranium production.  The Registrant intends to implement its strategy
through (i) continued capital expenditures for purposes of exploration and
development; (ii) the restart of developed mines currently on stand-by; (iii)
the purchase of uranium ore mined by third parties; (iv) the processing of
uranium bearing by-products; and (v) the continued mining of the Registrant's
uranium-producing properties.  The Registrant continues to actively pursue a
variety of exploration programs and targets, primarily for uranium, in a number
of countries around the world.

                                  AMALGAMATION

The predecessor, International Uranium Corporation ("Old IUC"), and Thornbury
were amalgamated effective May 9, 1997 under the provisions of the Business
Corporations Act (Ontario) to form the Registrant in accordance with the terms
of an agreement entered into between Old IUC and Thornbury dated February 13,
1997 (the "Amalgamation Agreement").  The primary purpose of the Amalgamation
was to effect an acquisition of Thornbury by Old IUC in that upon completion of
the Amalgamation the shareholders of Old IUC immediately prior to the
Amalgamation would hold the controlling interest in the Registrant, a public
company.

BACKGROUND ON THORNBURY

Thornbury was incorporated under the laws of Ontario on September 29, 1950.
Thornbury's common shares were quoted for trading on the Canadian Dealing
Network Inc. Thornbury's principal assets consisted of marketable securities
with a market value as at December 31, 1996 of Cdn$495,480 and eight mining
claims situated in the Mayo Mining District, Yukon Territory, which expire
between 1999 and 2009.

SHARE EXCHANGE RATIOS

The Amalgamation received the approval of the shareholders of both Old IUC and
Thornbury. On amalgamation, each shareholder of Old IUC received one (1) share
of the Registrant, a newly formed amalgamated company, for each one (1) common
share held in Old IUC, and each shareholder of Thornbury received one (1) share
of the Registrant for each five (5) common shares held in Thornbury.
Fractional shares resulting from the foregoing were rounded down to the next
whole number.

After giving effect to the amalgamation, there were a total of 65,743,066
common shares of the Registrant issued and outstanding.  This figure was based
on 26,500,000 previously issued common shares of Old IUC, 37,800,000 common
shares of Old IUC issued upon conversion of the special warrants and 7,215,334
common shares of





                                       7
<PAGE>   8



Thornbury which were outstanding prior to the amalgamation being effective
(1,443,066 post-amalgamation common shares).

AMALGAMATION AGREEMENT

Old IUC and Thornbury entered into an amalgamation agreement (the "Amalgamation
Agreement") which contained such representations and warranties, covenants,
indemnification and other provisions as are customarily found in an
amalgamation agreement entered into by parties dealing at arm's length.

                                  ACQUISITION

The Registrant entered the uranium industry by acquiring substantially all of
the uranium producing assets of Energy Fuels.  On December 19, 1996, Old IUC,
through its subsidiary, International Uranium Holdings Corporation, entered
into an agreement (the "Acquisition Agreement") to acquire the Energy Fuels'
Assets for cash of $20.5 million, subject to adjustment.  The terms of the
acquisition were approved by the United States Bankruptcy Court following a
lengthy bidding procedure as required under United States bankruptcy laws (see
"Bankruptcy of Oren Benton and Nuexco").  The acquisition was completed on May
9, 1997.

ENERGY FUELS

HISTORICAL BACKGROUND

The Energy Fuels group of companies was founded in August 1976 to capitalize on
uranium mining, purchasing and processing opportunities in the Colorado Plateau
area of western Colorado and eastern Utah. In the 1980's, Energy Fuels was one
of the largest producers of uranium in the United States. First efforts were in
the activation of old mines, exploration and development of new mines and the
construction of ore buying stations at Hanksville and Blanding, Utah.

In order to process the ores mined and purchased from the Colorado Plateau,
Energy Fuels commenced construction of a 2,000 ton per day mill near Blanding,
Utah in June 1979 at a total cost of approximately $40 million. Known as the
White Mesa Mill, the facility is a dual-circuit uranium mill.  Since its
start-up in May 1980, the White Mesa Mill, which also has a vanadium and other
co-product recovery circuit, has produced over 27 million pounds of uranium and
over 43 million pounds of vanadium in six separate milling campaigns.

The cost of construction of the White Mesa Mill was funded in large part by
Kernkraftwerk Goesgen-Daeniken AG, and Nordostschweizerische Kraftwerke AG, the
former limited partners in certain of the Energy Fuels Assets (the "Swiss
Utilities"), who, in consideration for this funding, acquired a 40% limited
partnership interest in all of Energy Fuels' United States assets. In 1995,
this 40% limited partnership interest was converted into a 9% royalty on all
uranium produced and a 5% royalty on vanadium and all other minerals produced
from the United States properties. The Swiss utilities have agreed to a
reduction in this royalty on most properties until December 31, 2000.  See
"Swiss Royalty Interest".

In the early 1980's Energy Fuels expanded its operations to include breccia
pipe uranium mining in the Arizona Strip district of northern Arizona. Since
1980, Energy Fuels had mined over 19 million pounds of uranium from seven mines
in the Arizona Strip. The land position of Energy Fuels in the Arizona Strip
district acquired by the Registrant includes three developed or partially
developed mines as well as several targeted mines and numerous other
exploration targets.

In 1984 Energy Fuels formed a limited partnership with Union Carbide
Corporation ("Union Carbide") pursuant to which Union Carbide acquired a 70%
undivided interest in and became the operator of the White Mesa Mill. As a
result of subsequent negotiations in 1987, Union Carbide's mines and properties
in the Colorado Plateau were added to this limited partnership and, as a
result, Energy Fuels acquired a 25% undivided interest in those mines. In 1994
this partnership was dissolved and Energy Fuels re-acquired 100% of the White
Mesa Mill as well as certain of Union Carbide's mines on the Colorado Plateau.
In the Colorado Plateau district, Energy Fuels then owned several uranium and
vanadium mines on standby, several partially developed mines as well as
additional acreage with exploration potential.

In 1994, in an effort to expand into the global uranium marketplace, Energy
Fuels acquired a 70% interest in a joint venture with the government of
Mongolia and a Russian geological concern to develop and produce uranium
reserves in Mongolia over a vast area.

In the early 1990's, Energy Fuels also acquired two significant ore bodies
intended to be mined by in-situ type mining technology: the Reno Creek property
in Wyoming, and the Dewey Burdock property in South Dakota.

From 1990 through the date of the Acquisition, Energy Fuels did not engage in
mining activities on its properties.

In early 1995, Energy Fuels filed for protection under Chapter 11 of the United
States Bankruptcy Code as a result of providing guarantees to an affiliated
company and its majority shareholder. See "Bankruptcy of Oren Benton and
Nuexco".

BANKRUPTCY OF OREN BENTON AND NUEXCO

On February 23, 1995, Oren L. Benton ("Benton") and two entities which Benton
controlled -- Nuexco Trading Corporation ("Nuexco") and CSI Enterprises, Inc.
("CSI") -- filed for protection under Chapter 11 of the United States
Bankruptcy Code.

Energy Fuels, Ltd. ("EFL") and Energy Fuels Exploration Company ("EFEX") filed
for protection under Chapter 11 of the United States Bankruptcy Code on
February 23, 1995. EFL and EFEX were both controlled by Benton through Energy
Fuels Mining Joint Venture ("EFMJV"). EFL and EFEX were forced into bankruptcy
because Benton, as controlling shareholder, caused them to guarantee certain of
Benton's and Nuexco's investment and trading activities. EFMJV filed for
protection under Chapter 11 on August 12, 1996.

The bankruptcy of Benton, Nuexco, CSI, EFL, EFEX and EFMJV involved numerous
other affiliated and subsidiary entities, of which Energy Fuels was a
relatively small part.

Under the provisions of Chapter 11 of the United States Bankruptcy Code, Benton
maintained control of the assets of his estate, including the Energy Fuels
Assets, but was under a fiduciary duty to reorganize his estate either under a
plan of reorganization or through the sale of portions of the assets from time
to time ("Section 363 Sales"). In order to protect the rights of creditors in
this process, a committee of selected creditors was formed (the "Creditors
Committee") as required under the provisions of Chapter 11 of the United States
Bankruptcy Code.

Benton and the Creditors Committee filed a joint Section 363 Sale motion on
October 21, 1996 with the Registrant as the lead bidder for the sale of the
Energy Fuels Assets to the Registrant for cash of $20.5 million, subject to
adjustments.

On December 4, 1996, the bankruptcy court approved the Acquisition Agreement
and the sale of the Energy Fuels Assets to the Registrant. The effect of the
court order was to eliminate substantially all known and existing claims and
liabilities of all creditors against the Energy Fuels Assets, so that the
Registrant would acquire the Energy Fuels Assets free and clear of all such
liabilities.

(2)    As stated by management of Registrant. Note, significant portions of
       these geological resources were stated by management of Registrant to be
       mineable reserves; however, in the time available, S2MS was not able to
       verify these reserves.

INDEPENDENT EXPERT'S REPORT

In September 1996, the Registrant engaged Saskatoon Mining & Mineral Services
Ltd. ("S2MS"), an independent engineering firm specializing in the uranium
industry, to review and report on certain of Energy Fuels' assets. S2MS
prepared a report entitled "Acquisition Study of Energy Fuels Nuclear Inc."
dated November 1996 (the "S2MS Report").

Where indicated, S2MS has reviewed certain of the reserves and other costs set
forth herein.

CALCULATION OF RESERVES AND RESOURCES

The Registrant maintains estimates of reserves and resources on the various
properties. The Registrant estimates that its properties (including Mongolia)
contained approximately 59 million pounds of U(3)O(8) as proven and probable
geological resources. In addition, the Registrant estimates that there are at
least another 40 million pounds of potential resources of U(3)O(8) in the
Arizona Strip area, and at least another 5 million pounds of potential
resources of U(3)O(8) in the Colorado Plateau area. In both cases, these
estimates of potential resources were based upon years of historical experience
in those areas. See "Arizona Strip -- Exploration Potential" and "Colorado
Plateau -- Exploration Potential".

Of these resources, the Registrant calculates 10.5 million pounds as mineable
in its current mine plan: 1 million from the Sunday Mine Complex;  0.4 million
from the Rim Mine; 1 million from the Arizona 1 Mine; 3 million





                                       11
<PAGE>   12
from the Canyon Mine (which includes 1 million pounds that are technically in
the potential reserve category but which management, based on years of
experience with breccia pipe mines, believes will be proven as mineable
reserves once underground drilling is completed in the course of mine
development); and 5.1 million pounds from the Reno Creek Property (to which a
75% recovery factor is applied). See "Sunday Mine Complex", "Rim Mine",
"Arizona 1 Mine", "Canyon Mine" and "Reno Creek Property".

The Registrant's current mine plan covers anticipated production for the next 5
years from the Sunday Mine Complex, the Rim Mine,  the Arizona 1 Mine and the
Canyon Mine and anticipated production from the Reno Creek Property over its
expected mine life of approximately 6 years.  The Registrant's current mine
plan does not address other mines that may also be brought into production
during the next 5 years at various price levels of U(3)O(8) and vanadium, nor
the additional reserves and mines that are expected to be developed in the
future, thereby extending the mining plan beyond 5 years.

The Registrant has accepted these reserve numbers and recovery factors as its
base case, rather than the slightly lower numbers calculated by S2MS, because
it believes that the historic production on the Colorado Plateau will continue
for many years to come; that past experience with breccia pipes leads to the
reasonable expectation that additional reserves will be delineated in the
Canyon Mine once underground drilling is completed; and that a 75% recovery
factor for the Reno Creek Property is reasonable, in light of the fact that
other positive factors for increasing reserves at that project have been
ignored.

Furthermore, the Registrant believes that the production estimates set out in
its current mine plan for the next five years can be continued for many
additional years depending on commodity prices, with the additional potential
on the Colorado Plateau and the Arizona Strip.

S2MS' CALCULATIONS OF RESERVES AND RESOURCES

As part of the Registrant's due diligence prior to the completion of the
bidding procedures for the Energy Fuels Assets, S2MS carried out a review of
the Sunday Mine Complex, the Arizona 1 Mine, the Canyon Mine, the Reno Creek
Property, the Dewey Burdock Property, the Mongolia Property and the White Mesa
Mill during the two months prior to the December  4, 1996 Section 363 Sale
confirmation hearing. S2MS spent approximately 1,500 hours completing their
review of these properties. However, given the limited amount of time
available, S2MS was not asked to review any other mines or properties of Energy
Fuels, and in particular did not review the Deer Creek, Rim, Egnar Plains,
Thunderbolt or Monogram mines on the Colorado Plateau, the Pinenut Mine on the
Arizona Strip, the Bull Frog Property or any of the exploration properties on
the Colorado Plateau or the Arizona Strip. In addition, given the absence of
historical data in some cases, S2MS was not able to fully evaluate all of the
reserves and resources in the Sunday Mine Complex.

Based on their review, S2MS was able to delineate mineable reserves of 9.1
million pounds. However, S2MS was unable to delineate all of the reserves in
the Registrant's mine plan.  The reserve estimates for the Arizona 1 Mine of 1
million pounds of U(3)O(8) were confirmed. However, because S2MS was not able
to recognize formally the additional 1 million pounds that the Registrant
delineated as mineable reserves at the Canyon Mine once underground drilling is
completed, S2MS was only able to delineate 2 million pounds of U(3)O(8) at the
Canyon Mine. Finally S2MS applied a recovery factor of 65% to the reserves at
the Reno Creek Property, compared to the 75% recovery factor applied by  the
Registrant, thereby reducing the number of pounds of uranium that is expected
to be recovered from those reserves by approximately 500,000 pounds.   In
addition, as S2MS was not asked to review the Rim Mine, the 364,000 lbs. of
U(3)O(8)  and  3,460,000 lbs. of V(2)O(5) in the current mine plan for the Rim
Mine were not included in S2MS's report.  See "Rim Mine".

In its report, however, S2MS did recognize that it was unable to fully evaluate
all of the reserves at the Sunday Mine Complex, given the lack of time and data
and that additional potential exists. S2MS also acknowledged that it is
possible that with additional underground drilling at the Canyon Mine, the
Registrant's estimate of 3 million pounds of reserves at that mine could be
achieved. Finally, S2MS acknowledged that potential exists at the Reno Creek
Property to delineate additional reserves.

CLAIMS ARISING OUT OF THE ACQUISITION

Under the Acquisition Agreement, Energy Fuels made certain representations and
warranties concerning title to the various properties and mining claims
acquired by the Registrant and various other matters.  Energy Fuels agreed to
indemnify the Registrant from any losses and damages incurred by the Registrant
(subject to a cap of $1,500,000) and arising out of a breach of Energy Fuels'
representations and warranties.  A total of $1,500,000  of the purchase price
paid by the Registrant was placed in escrow to secure Energy Fuels' indemnity
obligations.  On May 8 and 9, 1998, the Registrant submitted a claim against
all amounts held in escrow alleging various breaches of Energy Fuels'
representations and warranties.  The liquidating trustee for the bankruptcy
estates of Energy Fuels has denied the claims of the Registrant.  At this time,
it is not known whether the Registrant will prevail on its claims against the
amounts held in escrow or the amount, if any, to be recovered on such claims.

                                  RISK FACTORS

VOLATILITY AND SENSITIVITY TO PRICES, COSTS AND EXCHANGE RATES

Because a significant portion of the Registrant's revenues are expected to be
derived from the sale of uranium and vanadium, the Registrant's net earnings
will be closely related to the long- and short-term market price of U(3)O(8)
and V(2)O(5). Historically, uranium prices have been subject to fluctuation,
and the price of uranium has been and will continue to be affected by numerous
factors beyond the Registrant's control, such as demand for nuclear power,
political and economic conditions in uranium producing and consuming countries,
such as the United States, Canada and Russia and other republics of the CIS,
and production levels and costs of production in countries such as Russia,
Canada and other republics of the CIS and Australia.

COMPETITION FROM ALTERNATIVE ENERGY SOURCES AND PUBLIC ACCEPTANCE OF NUCLEAR
ENERGY

Nuclear energy competes with other sources of energy, including oil and gas,
coal and hydro-electricity. These alternative energy sources are to some extent
interchangeable with nuclear energy, particularly over the longer term. Lower
prices of oil, gas, coal and hydro-electricity for an extended period of time
may make nuclear power a less attractive fuel source for the generation of
electricity, thus resulting in lower demand for uranium. Furthermore, the
growth of the uranium and nuclear power industry beyond its current level will
depend upon continued and increased acceptance of nuclear technology as a means
of generating electricity. Because of unique political, technological and
environmental factors that affect the nuclear industry, the industry is subject
to public opinion risks which could have an adverse impact on the demand for
nuclear power and increase the regulation of the nuclear power industry.

URANIUM INDUSTRY COMPETITION AND INTERNATIONAL TRADE RESTRICTIONS

The international uranium industry is highly competitive in many respects,
including the supply of uranium. The Registrant markets uranium to utilities in
direct competition with supplies available from a relatively small number of
Western World uranium mining companies, from certain republics of the CIS and
Mainland China and from excess inventories, including inventories made
available from decommissioning of military weapons. To some extent the effects
of the supply of uranium from the CIS republics are mitigated by a number of
international trade agreements and policies, including suspension agreements
entered into by the United States with certain republics of the CIS, including
Russia, that restrict imports into the United States market. In addition, in
January 1994, the United States and Russia signed a 20-year agreement to
convert HEU from former Russian nuclear weapons to a grade suitable for use in
nuclear power plants. During 1995, the United States also amended its
suspension agreements with the Republics of Kazakhstan and Uzbekistan, which
increased the limit on the supply of uranium from those republics into the
United States for a 10-year period. The European Community also has an informal
policy limiting annual consumption of uranium sourced from the CIS republics.
These agreements and any similar future agreements, governmental policies or
trade restrictions are beyond the control of the Registrant and may affect the
supply of uranium available in the United States, which is the largest market
for uranium in the world.

IMPRECISION OF RESERVE AND RESOURCE ESTIMATES

Reserve and resource estimates included in this document for uranium and
vanadium are estimates, and no assurances can be given that the indicated
levels of recovery will be realized. Such estimates are expressions of judgment
based on knowledge, mining experience, and analysis of drilling results and
industry practices. Valid estimates made at a given time may significantly
change when new information becomes available. While the Registrant believes
that the reserve and resource estimates included in this document are well
established and reflect management's best estimates, by their nature, reserve
and resource estimates are imprecise and depend, to a certain extent, upon
statistical inferences which may ultimately prove unreliable. Furthermore,
market price fluctuations in uranium and vanadium, as well as increased
production costs or reduced recovery rates, may render ore reserves containing
lower grades of mineralization uneconomic and may ultimately result in a
restatement of reserves. The extent to which resources may ultimately be
reclassified as proven or probable reserves is dependent upon future
inspection, sampling, and measurement. The evaluation of resources or reserves
is also influenced by economic and technological factors, which may change over
time. Resource figures included here have not been adjusted in consideration of
these risks and, therefore, no assurances can be given that any resource
estimate will ultimately be reclassified as proven or probable reserves.

REPLACEMENT OF RESERVES

The Sunday Mine Complex, Rim, Arizona 1, Canyon and Reno Creek Mines are the
Registrant's principal sources of uranium at this time. Unless uranium
properties such as Dewey Burdock and Mongolia are developed and placed into
production or other reserves on the Colorado Plateau, the Arizona Strip or
elsewhere are discovered or extensions to existing ore bodies are found, the
Registrant's total uranium reserves will decrease over time as its current
uranium producing properties are depleted. Although in the past the
Registrant's predecessors have successfully replenished their reserves through
ongoing exploration, development and acquisition programs, there can be no
assurance that additional uranium properties will be developed and placed into
production or that the Registrant's future exploration, development and
acquisition efforts will be successful.

MINING RISKS AND INSURANCE

The mining of uranium is a capital intensive commodity business, and is
generally subject to a number of risks and hazards, including environmental
pollution, accidents or spills, industrial accidents, labor disputes, changes
in the regulatory environment, natural phenomena (such as inclement weather
conditions, underground flooding and earthquakes), and encountering unusual or
unexpected geological conditions. Many of the foregoing risks and hazards could
result in damage to, or destruction of, the Registrant's mineral properties,
personal injury or death, environmental damage, delays in or cessation of
production from the Registrant's mines or in its exploration or development
activities, monetary losses and potential legal liability. In addition, due to
the radioactive nature of the materials handled in uranium mining and milling,
additional costs are incurred by the Registrant on a regular and ongoing basis.


The Registrant intends to maintain insurance against certain risks that are
typical in the uranium industry, including business interruption insurance for
the White Mesa Mill. Although the Registrant maintains insurance in amounts it
believes to be reasonable, such insurance may not provide adequate coverage in
the event of certain unforeseen circumstances. Insurance against certain risks
(including certain liabilities for environmental pollution or other hazards as
a result of production, development or exploration), is generally not available
to the Registrant or to other companies within the uranium mining and milling
business.

GOVERNMENTAL REGULATION AND POLICY RISKS

Mining and milling operations and exploration activities, particularly uranium
mining and milling in the United States, are subject to extensive regulation by
state and federal governments. Such regulation relates to production,
development, exploration, exports, taxes and royalties, labor standards,
occupational health, waste disposal, protection and remediation of the
environment, mine reclamation, mine safety, toxic substances and other matters.
Compliance with such laws and regulations has increased the costs of exploring,
drilling, developing, constructing, operating and closing the Registrant's
mines and other facilities. It is possible that, in the future, the costs,
delays and other effects associated with such laws and regulations may have an
impact on the Registrant's decisions as to whether to continue to operate
existing mines or refining and other facilities or, with respect to exploration
and development properties, whether to proceed with exploration or development.
Furthermore, future changes in governments, regulations and policies, could
materially adversely affect the Registrant's results of operations in a





                                       14
<PAGE>   15



particular period or its long-term business prospects. In addition, should
certain recent proposals being considered by the U.S. Congress become law, a
royalty on production of minerals from unpatented mining claims located on
federal lands could be imposed, which could adversely impact the Registrant's
proposed business and uranium prospects.

Worldwide demand for uranium is directly tied to the demand for energy produced
by the nuclear electric industry, which is also subject to extensive government
regulation and policies in the United States and elsewhere. The development of
mines and related facilities is contingent upon governmental approvals which
are complex and time consuming to obtain and which, depending upon the location
of the project, involve various governmental agencies. The duration and success
of such approvals are subject to many variables outside the Registrant's
control. In addition, as described below under "The Uranium Industry", the
international marketing of uranium is subject to certain trade restrictions,
such as those imposed by the suspension agreements entered into by the United
States with certain republics of the CIS and the agreement between the United
States and Russia related to the supply of Russian HEU into the United States.

ENVIRONMENTAL RISKS

The Registrant has expended significant resources, both financial and
managerial, to comply with environmental protection laws and regulations and
permitting requirements, and the Registrant anticipates that it will be
required to continue to do so in the future. Although the Registrant believes
that its operations are in compliance, in all material respects, with all
relevant permits, licenses and regulations involving worker health and safety
as well as the environment, the historical trend toward stricter environmental
regulation may continue. The uranium industry is subject to not only the worker
health and safety and environmental risks associated with all mining
businesses, but also to additional risks uniquely associated with uranium
mining and milling. The possibility of more stringent regulations exists in the
areas of worker health and safety, the disposition of wastes, the
decommissioning and reclamation of mining and milling sites, and other
environmental matters, each of which could have a material adverse effect on
the costs or the viability of a particular project.

DEPENDENCE ON LIMITED NUMBER OF CUSTOMERS

The Registrant expects that it will rely heavily on a relatively small number
of customers to purchase a significant portion of its production of uranium.
The loss of any of the Registrant's largest customers or curtailment of
purchases by such customers could have a material adverse effect on the
Registrant's financial condition and results from operations.

MONGOLIA PROPERTY

An important component of the Registrant's business plan is the development of
the Mongolia Property in Mongolia. As with any foreign operation, the Mongolia
Property may be subject to certain risks, such as adverse political and
economic developments in Mongolia, foreign currency controls and fluctuations,
as well as risks of war and civil disturbances. Other events may limit or
disrupt the project, restrict the movement of funds, result in a deprivation of
contract rights or the taking of property by nationalization or expropriation
without fair compensation, increases in taxation or the placing of limits on
repatriation of earnings. No assurance can be given that current policies of
Mongolia or the political situation within that country will not change so as
to affect adversely the value or continued viability of the Registrant's
interests in the Mongolia Property. The Registrant intends to monitor this
investment with a view to anticipating political, economic or other events that
may affect the Registrant's interests in the Mongolia Property.

TITLE

The Registrant is satisfied that it has good and proper right, title and
interest in and to the mining properties that it intends to explore and
develop, subject to the description of such properties appearing elsewhere in
this document. No assurance, however, can be given that such properties are not
subject to prior unregistered agreements or interests or undetected claims or
interests, which could be material and adverse to the Registrant.





                                       15
<PAGE>   16



RELIANCE ON ALTERNATE FEED REVENUE

A significant portion of the Registrant's expected revenues and income over the
next several years is expected to result from the processing of Alternate Feed
Materials through the White Mesa Mill.  See ""Alternate Feeds".

Although the Registrant believes that Alternate Feed sources will continue to
generate revenues and income for the Registrant over this time period, there
can be no guarantees or assurance that this will be the case.

DEPENDENCE ON KEY PERSONNEL

The Registrant's success will largely depend on the efforts and abilities of
certain senior officers and key employees. Certain of these individuals have
significant experience in the uranium mining industry. The number of
individuals with significant experience in this industry is small. While the
Registrant does not foresee any reason why such officers and key employees will
not remain with the Registrant, if for any reason they do not, the Registrant
could be adversely affected. The Registrant has not purchased key man life
insurance for any of these individuals.

CONFLICTS OF INTEREST

Certain of the directors of the Registrant also serve as directors of other
companies involved in natural resource exploration and development, and
consequently there exists the possibility for such directors to be in a
position of conflict. Any decision made by such directors involving the
Registrant will be made in accordance with the duties and obligations of
directors to deal fairly and in good faith with the Registrant and such other
companies. In addition, such directors must declare, and refrain from voting
on, any matter in which such directors may have a conflict of interest.

ITEM 2 - DESCRIPTION OF PROPERTY

The following is an overview of the properties currently held by the
Registrant:

                                WHITE MESA MILL

OVERVIEW

The White Mesa Mill is located approximately 6 miles south of the city of
Blanding, Utah. Access is by state highway.

Construction of the White Mesa Mill (also referred to herein as the "Mill")
started in 1979, and ore was first processed in May 1980.  The Mill is in
compliance with NRC and EPA standards and is a dual-circuit uranium mill. The
cost of constructing the Mill and tailings ponds was approximately $40 million.


The Mill is a standard design with both uranium and vanadium circuits.
Nameplate capacities are 2,000 tons per day of ore, 6 million pounds uranium
per year from Arizona Strip ore or 3-1/2 million pounds per year of uranium
from Colorado Plateau ore, and up to 18 million pounds per year of vanadium.
Since its commissioning in May 1980, the Mill has produced over 27 million
pounds of uranium and over 43 million pounds of vanadium in 6 separate milling
campaigns in 1980-83, 1985-1988, 1989-1990, 1995, 1996, and 1997.

The ore is received at the White Mesa Mill and stockpiled. Amenability tests
are run on ore lots from individual mines to determine if blending of the ores
will increase overall recovery. The ore is initially fed to an 18-foot diameter
SAG Mill, then stored in slurry form in one of the two pulp storage tanks. The
White Mesa Mill utilizes a two-stage leach process where overflow solution from
the No. 1 CCD Thickener is combined, in an "acid kill" step, with feed from the
pulp storage tanks. The slurry from this first stage leach is then separated in
the pre-leach thickener, with the solids going to the second stage leach and
the solution is clarified and sent to the solvent extraction circuits.
Concentrated sulfuric acid, steam, and an oxidizer are added in the second
stage leach. This slurry is subsequently fed to the 8-stage CCD Circuit where
the underflow is discharged to tailings.

In full operation, the Mill employs approximately 100 people.





                                       16
<PAGE>   17



CURRENT CONDITION

The Mill is generally in good operating condition, but with a need for capital
expenditures to reline tailings Cell #4A, and refurbish the vanadium circuit
before vanadium can be produced. The claricone clarifier has failed
structurally and has been repaired once. Further repairs are currently required
at an estimated cost of  $15,000, should it be deemed that the claricone
clarifier will be necessary for future operations. Since the date of the
acquisition, approximately $400,000 has been spent refurbishing the vanadium
circuit, which is expected to be fully restored by mid 1998.

TAILINGS

Synthetic lined cells are used to contain tailings and, in one case, solutions
for evaporation. Currently there is sufficient volume available for another
500,000 tons of tailings solids. Thereafter, an additional cell will be needed,
at a cost of approximately $2.5 million.

The current license for the Mill permits that a total of three forty-acre
tailings cells may be added. Each additional tailings cell can accommodate
approximately two million tons of tailings, for a total of nine years of
operation at 2,000 tons per day.

Difficulties have been encountered with leaking seams in the liner for Cell
#4A. This cell contains no tailings at present, and leaking is due to working
of the liner by thermal stress, since it is exposed to full sunlight. The cell
must be relined with a better quality material before using it to deposit
tailings.  The Registrant estimates an expenditure of $1.5 million for this
purpose.

REQUIRED CAPITAL EXPENDITURES

Four significant capital projects are anticipated over the next three years
with respect to operation of the White Mesa Mill:

</TABLE>


       *      To date, approximately $400,000 has been spent in connection with
              refurbishing the vanadium circuit.

RECENT OPERATIONS

Since January of 1995 the White Mesa Mill has completed three campaigns: the
processing in 1995 and 1996 of approximately 200,000 tons of stockpiled ore,
mainly from the Arizona Strip; the processing in 1996 of an alternate feed
source, and the processing in 1997 of three alternate feed sources. The
Registrant is currently processing an additional alternate feed source in 1998,
in another campaign. Except for the milling campaigns in 1995 and 1996, the mill
was not in active operation for the seven year period prior to the Acquisition.

OPERATION AT REDUCED CAPACITY

The White Mesa Mill in its current design capacity, 2,000 tons per day, is
oversized for the foreseeable tonnages expected over the next few years. The
Mill is currently only capable of milling ore at its full design capacity. The
larger the capacity, the larger the interval between Mill runs, as ore is
stockpiled to provide adequate Millfeed.

The Registrant proposes to bring the White Mesa Mill into production at a
reduced effective capacity of approximately 750 tons per day. (1050 tons per
day, operating 5 of 7 days per week).  This will allow the Mill to be run more
frequently and will reduce the amount of time that ore is stockpiled waiting
for processing. However, the unit cost of milling ore increases as the capacity
of the Mill is reduced.

Running at a lower tonnage is possible if relatively minor modifications are
made to the Mill. The Registrant estimates that the capital expenditure
required to reduce the capacity of the Mill is approximately $100,000, and that
the capital expenditures required to increase capacity at a later date are
approximately the same.   Approximately one half of this amount has been spent
in preparation for alternate feed processing in 1998.

CLOSURE

The estimate of closure costs for the White Mesa Mill was revised by the
Registrant after discussion with the NRC and reviewing costs for demolition.
The current estimated closure costs are summarized as follows:

</TABLE>


(1)    In the S2MS report, S2MS was asked to review the cost estimates for the
       reclamation of the Mill.  As a check, S2MS determined that this equates
       to 35,000 hours @ $40/hour which S2MS concluded should be sufficient for
       this work. S2MS concluded that some equipment could be salvaged and
       resold, for example the grinding mill and drive, agitators, gearboxes,
       etc. S2MS concluded that as much as $1 million could be realized,
       although this has not been included.

(2)    The tailings cells are filled up to a 5 foot freeboard then the walls
       are "contoured" and the cell contents covered with four layers of
       material- a 4 foot random fill, then a 2 foot clay cover (to stop radon
       emission), then another 2 feet of random fill, and finally a 2 inch top
       cover of crushed and compacted rock. The last layer is meant to prevent
       re-vegetation on the surface that root action might open as a pathway
       for radon emission.

       The closure plan would involve transfer of solution from Cell #4A to
       Cell #3, followed by sediment and the plastic lining. Cell #2 is already
       nearly covered; Cell #3 is partially covered.

(3)    The total estimated reclamation costs are bonded.  The Registrant has
       posted security in the amount of 65% of the bond amount. See "White Mesa
       Mill -- Reclamation Bond".

(4)    The cost estimate for reclaiming tailings Cell #4A assumes that no
       tailings sands are deposited in Cell #4A. Tailings sands are expected to
       be deposited in to Cell #4A in the second year of operations. Once
       tailings sands are deposited in tailings Cell #4A, the reclamation cost
       of that cell will be approximately $2 million.

SEQUENTIAL RECLAMATION

Under the Mill's NRC permit, the Mill is only allowed to have two tailings
cells open at any one time. Prior to depositing tailings in to Cell #4A, the
Registrant intends to close tailings Cell #2 and commence reclamation of Cell
#2 for approximately $1,675,000. This will allow tailings Cell #4A to be
opened. The result is that the total cost of reclamation at any one time, and
hence the amount of the bond required, is not expected to increase as Cell #4A
is brought into use.

As each pond, or cell, is filled with tailings, the water is drawn off and
pumped to the evaporation pond and the sands allowed to dry. As each cell
reaches final capacity, reclamation will begin with placement of 6 to 8 feet of
clay and rock over the tailings. Additional cells are excavated into the
ground, and the overburden is used to reclaim previous cells. In this way there
is an ongoing reclamation process, and the total cost of reclamation at any
point in time is not expected to increase significantly over the amounts set
out in the table above, other than due to inflationary factors.

                           COLORADO PLATEAU DISTRICT

OVERVIEW

The Uravan mineral belt in the Colorado Plateau (the "Colorado Plateau
District") has a lengthy mining history, with the first ore shipment made to
France in 1898. World War II brought increased attention to the uranium ores in
the Uravan area, and by the 1950's this district was one of the world's
foremost producers of both uranium and vanadium. Production continued more or
less uninterrupted until 1984 when low uranium prices forced the closure of all
operations. Production resumed in 1987 but once again ceased in 1990. Total
production from the Union Carbide mines (many of which were later purchased by
Energy Fuels, and hence the Registrant) in the Uravan area is reported at 47
million pounds of U(3)O(8) and 273 million pounds of vanadium, yielding an
overall ratio of V(2)O(5)/U(3)O(8) of 5.79.

EXPLORATION POTENTIAL

The types of uranium reserves found in the Colorado Plateau were deposited as
alluvial fans by braided streams. The shape and size of the ore seams are
extremely variable. As a result, exploration and mining have historically to a
large part involved conducting exploration to find a seam and then merely
following its erratic path, with little additional exploration other than
development drilling in the course of following the seam. This is unlike other
types of mining where ore bodies are almost completely delineated by
explorative drilling prior to mining.

The unusual nature of these ore bodies has therefore traditionally resulted in
a limited amount of resources being dedicated to delineate reserves prior to
mining. Traditionally, there will be some ore reserves that have been
delineated at the beginning of each year, uranium will be mined during the year
and approximately the same amount of reserves will remain delineated at the end
of the year. This pattern has persisted since the 1940's.

Mining stopped on the Colorado Plateau in 1990 as a result of low uranium and
vanadium prices and not as a result of the depletion of reserves.





                                       20
<PAGE>   21



Based on this history of production from the Colorado Plateau, the Registrant
believes that the potential to continue this pattern of production exists for
many years to come and that additional reserves will be delineated each year as
mining continues.

Presently 1.3 million pounds of mineable reserves of uranium and 10.3 million
pounds of additional geological resources of uranium have been identified by
the Registrant. The Registrant has also identified 10.5 million pounds of
mineable resources of vanadium and 55 million pounds of additional geological
resources of vanadium. In addition, the Registrant has identified several
previously unexplored prospective areas in the Colorado Plateau between
existing mines.

GEOLOGY

The Registrant's properties on this geographic area are typical uranium-
vanadium deposits of the Colorado Plateau type located in the southern end of
the Uravan mineral belt.  The rocks of the Colorado Plateau are predominately
sedimentary ranging in age from Precambrian to Tertiary and, although uranium
mineralization occurs in sediments of different ages, the most important
deposits of the Uravan belt occur in the Salt Wash Member of the Jurassic
Morrison Formation.

The Salt Wash Member consists of light gray to light brown sandstones
interbedded with red-green siltstones and mudstones.  The sandstones, which are
generally fine-grained and well to moderately sorted, are considered to have
been deposited as alluvial fans by braided streams.  The mineralization occurs
in the lenticular sandstone deposits as tabular, elongate bodies generally
parallel to the bedding following the palaeo-channels.  All of the large
deposits within the Morrison Formation are in the upper sandstone lens of the
Salt Wash Member, commonly known as the third rim.  Fine-grained uraninite is
the sominant uranium mineral accompanied by lesser amounts of coffinite.  The
chief vanadium mineral is nontrosite.  In the oxidized parts of the deposits
the distinctive yellow coloured uranyl-vanadate mineral, carnotite, is common.

Individual deposits are small, varying in length from a few hundred to several
thousand feet and in width from a hundred to a thousand feet.  Thicknessesses
vary from a few inches to several tens of feet, but generally average between
two to five feet.  Mines often contain several such ore bodies.  The host
sediments are generally flat lying to low dipping with little structural
deformation.

The Registrant's principal mining complexes on the Colorado Plateau District
consist of the Deer Creek, Monogram, Thunderbolt, Sunday, Egnar Plains and East
Canyon (Rim) zones.

The Registrant has also established a central office, maintenance shop, and
equipment storage facility at Dove Creek, Colorado approximately 60 miles south
of the Sunday Mine Complex. This facility is used for major repair work such as
overhauls and is centrally located to serve several widely spaced mines

The bulk of the reserves and resources and the nearest term mining potential in
the Colorado Plateau District are contained in three areas, the Sunday Mine
Complex, the Deer Creek complex, which includes the La Sal and Pandora, mines
and the East Canyon Area, which includes the Rim Mine, all of these areas have
developed, permitted mines, with the Sunday and Rim Mines currently in
production.  Production at certain other mines in these areas could be resumed
on relatively short notice. Given the limited time available, only the Sunday
Mine Complex, which is currently in production, was examined by S2MS. See
"Sunday Mine Complex".   Since the Acquisition, given the current high prices
of V(2)O(5), the Registrant has elected to bring the Rim Mine into production.
The Rim Mine has a high ratio of V(2)O(5) to U(3)O(8).  See "Rim Mine".

                              SUNDAY MINE COMPLEX

OVERVIEW

The Sunday Mine Complex is located in the Colorado Plateau District of Colorado
approximately 100 miles by road from the White Mesa Mill. Access is by state
highway and county roads.

The Sunday Mine Complex is comprised of the Sunday, West Sunday, Carnation,
Topaz, Le May and Leonard Clark zones which are contiguous or near contiguous
partially worked mines and virgin exploration areas.





                                       21
<PAGE>   22



The Sunday Mine Complex is held by the Registrant under a large number of 1,500
feet x 600 feet rectangular standard BLM mining claims, some of which were
owned outright and some of which were purchased or leased from former holders
and are subject to various NSR royalty agreements.

The Sunday Mine Complex is one of several mining areas owned by the Registrant
in the Colorado Plateau District. See "Colorado Plateau District".

PERMITTING

The Sunday Mine Complex is permitted for mining. However, recent changes in
Colorado laws gives the Colorado state authorities the right to require mines
such as the Sunday Mine Complex in certain circumstances to submit a revised
Environmental Protection Plan for approval when mining activities are
re-initiated. See "Permitting".  Mining activities have commenced at the Sunday
Mine Complex and as of the filing date the Registrant has not been notified of
any additional permitting requirements.

GEOLOGICAL RESOURCES

The geological resources of the Sunday Mine Complex, calculated by the
Registrant, are 845,400 tons grading approximately 0.21% U(3)O(8)  and
approximately 1.40% V(2)O(5) resulting in 3,493,700 pounds of U(3)O(8) and
23,612,300 pounds of V(2)O(5).

Prior to the acquisition of the Energy Fuels assets, the Registrant asked S2MS
to evaluate the Sunday Mine Complex ore reserve estimates.  Due to time
constraints, an assessment of the reserve by S2MS focused on the West Sunday
area and new areas immediately available to new development from the West
Sunday workings. These are the Le May zone, Leonard Clark zone and West Sunday
zone itself. In addition, S2MS spent some time attempting to verify the
resource estimates for the Sunday and Carnation zones but found that there was
not sufficient data to verify all these resources, in the time available.

The final probable geologic resources for the Sunday Mine Complex zones
calculated by S2MS, including approximately 50,000 tons from the Carnation
zone, were 318,190 tons grading approximately 0.25% U(3)O(8) and approximately
1.69% V(2)O(5) resulting in 1,594,690 pounds of U(3)O(8) and 10,682,050 pounds
of V(2)O(5).

The overall total for the Le May, Leonard Clark and West Sunday zones compares
with 235,000 tons grading 0.24% U(3)O(8) quoted for the same areas by Energy
Fuels which makes the S2MS estimate 14% higher in tons and 19% higher in
contained pounds of U(3)O(8). As a result, S2MS has concluded that the
estimates made by Energy Fuels for these areas were slightly conservative and
are realistic numbers for planning future mining operations.

SUNDAY MINE COMPLEX -- MINING

MINEABLE RESERVES

The Registrant's ore reserve for the Sunday Mine Complex includes a total of
845,400 tons at 1.40% V(2)O(5) and 0.21% U(3)O(8). As discussed above, only a
portion of the reserve areas addressed in that statement were independently
verified by S2MS and included in the S2MS Report. Based on the geological
resources that S2MS was able to verify with the available data, mineable ore
reserves as calculated by S2MS were 221,579 tons grading approximately 0.24%
U(3)O(8) and approximately 1.67% V(2)O(5), resulting in 1,070,124 pounds of
U(3)O(8) and 7,393,822 pounds of V(2)O(5).

MINE DEVELOPMENT

The Sunday Mine Complex is accessed by a number of declines from surface. The
declines grade at approximately minus 12% and are collared in the valley wall
and generally follow the ore zones down, which dip at about 11 degrees. The
valley rises up steeply over the ore zones such that at the top of the valley
wall the ore is some 800 feet below surface.

Originally each of the mines in the Sunday Mine Complex were developed as
separate stand alone mines, but now they have been joined together by drifts
such that they can be considered as one extensive mine.

The Sunday Mine Complex is an operating mine and as such has all the necessary
facilities required for operations. Adjacent to the West Sunday portal is a
building containing a single bay maintenance shop, change room, office and





                                       22
<PAGE>   23



small warehouse. A second building houses a compressor. Water, electricity, and
other services are all installed. At the Sunday portal one building houses a
four bay maintenance shop and a second building provides a change room and
offices. There are several other utility buildings as well at this site. As the
Sunday Mine was operated as a separate mine it is set up as a stand-alone
facility with all the required services installed.

An additional building housing a compressor is located on the hill above the
West Sunday. A number of ventilation fans remain installed on the collar of
ventilation raises.

Additional access and ventilation development is required for mining of certain
ore zones. A 2,400-foot long drift from the Topaz to the Le May zone is being
driven and a new 700-foot long vertical borehole to surface would be bored to
supply ventilation to the zone. To further develop the West Sunday ore, 600
feet of additional drifting is required to connect the upper and lower West
Sunday ore zones.

MINING METHODS

The mining method is random room and pillar in which no set pillar pattern is
established but rather both the sizes of the rooms and the pillars is left up
to the operators on a day to day basis. Whenever possible, pillars would be
left in waste or low-grade areas. A typical room is about 20 feet wide with
pillars as small as 12 feet square in highly mined areas.

Because of the limited height of the ore, mining must necessarily be quite
selective in order to maintain a satisfactory production grade. This is done by
following the ore zones closely and by the technique of "split shooting"
wherein the ore and waste are blasted separately in a two-stage operation.

Miners are generally organized into small production teams, each operating in a
different area of the mine. Drilling is carried out by hand held jacklegs. Each
drill crew is assigned a vehicle equipped with a full set of gear for drilling
so that location changes can be made quickly and efficiently. Mucking is
accomplished by one or two cubic yard scooptrams loading ore or waste into 8 or
10 ton trucks for haulage to surface. Ore is dumped in a stockpile near the
portal collar.

The surface truck haulage contractor is responsible for loading his own trucks
as well as hauling the ore to the Mill near Blanding, Utah.  PRODUCTION
FORECAST AND SCHEDULE

Based on 200 tons per day for a five-day week and 250 working days per year, an
annual production rate of 50,000 tons or 230,000 pounds of recoverable uranium
and 1.3 million pounds of recoverable vanadium is considered by the Registrant
to be reasonable.

The Registrant began actual ore production from the Sunday Mine Complex in
November of 1997 after several months of mine dewatering and general
refurbishment.  The Registrant also began refurbishment of the old Topaz
decling, and driving new decline toward the LeMay orebody.  As of the end of
April 1998, the Registrant had produced 16,084 tons of ore.

OPERATING COSTS

The Registrant based on experience and expected vanadium prices estimates that
its total mining and milling costs will be in the range of $9.00 to $12.50 per
lb. of uranium produced from the Sunday Mine Complex.

The Registrant is evaluating options to contract out a portion of the east end
of the Sunday Mine Complex (the GMG area) to an independent contractor.  The
approach would be an all-inclusive one in which the contractor would be
responsible for all mining activities and support services. The contractor
would pay for power, fuel, maintenance of all equipment and buildings, roads,
as well as direct mining costs. The Registrant would compensate the contractor
by paying the contractor for tons of ore delivered at the White Mesa Mill. To
encourage good grade control, the mining contract would be set up to pay a
premium for increasing ore grade relative to the reserve grade.  The payment
basis would be recalculated monthly based on the current market prices of
uranium and vanadium.  The contractor would assume all risk for profit and loss
based on his ability to maintain profitable quantities and grades of ore from a
mostly depleted reserve area.

<PAGE>   24



PURCHASED ORE

In order to supplement its own mining operations and production, the Registrant
has entered into agreements with other independent miners in the Colorado
Plateau region to purchase their ore based on a schedule which takes into
account the U(3)O(8) and V(2)O(5)  content of the ore, current market prices,
and appropriate discounts for milling costs and profits.  It is anticipated
that these purchase prices will compare favorably with the company's own mining
costs for similar  ore.

                                    RIM MINE

OVERVIEW

The Rim Mine is located in the Colorado Plateau District of Utah approximately
60 miles by road from the White Mesa Mill.  Access is by state highway and
county roads.

The Rim Mine is comprised of the Rim, Cressler, Columbus, and Humbug claims,
which are contiguous or near contiguous partially worked mines and virgin
exploration areas.

The Rim Mine is held by the Registrant under a large number of 1,500 feet x 600
feet rectangular standard load mining claims, some of which are owned outright
and some of which are leased and are subject to various royalty agreements.

The Rim Mine is one of several mining areas owned by the Registrant in the
Colorado Plateau District. See "Colorado Plateau District ".

PERMITTING

The Rim Mine is permitted for mining by the State of Utah Division of Oil ,Gas
and Mining.  The Mine has a current Utah NPDES (National Pollution Discharge
Elimination System) Permit allowing for treatment and discharge of excess mine
water.

GEOLOGICAL RESOURCES

The geological resources of the Rim Mine, calculated by the Registrant, are
108,000 tons grading approximately 0.18% U(3)O(8) and approximately 1.72%
V(2)O(5) resulting in approximately 394,800 pounds of U(3)O(8) and
approximately 3,712,400 pounds of V(2)O(5). The Registrant projects an
additional 40,000 tons of probable ore reserves based on geologic favorability
and nearness to the known orebody at the Rim Mine.  These probable reserves
contain 152,000 pounds of U(3)O(8) and 1,528,000 pounds of V(2)O(5) at grades
of 0.19%  U(3)O(8) and 1.91% V(2)O(5).

MINEABLE RESERVES

The Registrant's ore reserve for the Rim Mine includes a total of 100,000 tons
at 0.182% U(3)O(8) and 1.73% V(2)O(5) resulting in 364,000 pounds of U(3)O(8)
and 3,460,000 pounds of V(2)O(5).

MINE DEVELOPMENT

The Rim Mine is accessed by a single vertical shaft, 500 feet in depth, and a
decline from the adjacent canyon wall. The decline grades at approximately
minus 6%, and is collared in the valley wall and generally follows the ore
zones down.

The Rim Mine was an operating mine when it was shut down in 1990. The
Registrant re-commenced mining activities in early 1998.  Adjacent to the shaft
is a small building containing a single bay maintenance shop, change room,
office and small warehouse. A second building houses a compressor. Water,
electricity, and other services are all installed. At the Rim portal only basic
surface facilities are in place.  The mine plan calls for ventilation and mine
dewatering to be facilitated through the vertical shaft and for all mine waste
and ore removal to take place through the decline.  The mine was allowed to
flood after it was shut down in 1990, and consequently required a significant
amount of cleanout and repair prior to mining.

MINING METHODS

The mining method is random room and pillar in which no set pillar pattern is

The Rim mine is being operated as a contract mine.  The contractor is
responsible for all mining activities and support services.  The contractor is
operating the mine and pays for power, fuel, maintenance of all equipment and
buildings, roads, as well as direct mining costs. The Registrant compensates
the contractor by paying the contractor for tons of ore delivered at the White
Mesa Mill. To encourage good grade control, the mining contract has been set up
to pay a premium for increasing ore grade relative to the reserve grade. The
payment basis is recalculated monthly based on the current market prices of
uranium and vanadium.  The contractor has assumed all risk for profit and loss
based on his ability to maintain profitable quantities and grades of ore from
the current reserve area.  The contractor is responsible for haulage of the ore
to the Mill near Blanding, Utah, as part of the per ton contract rate.  Based
on the current payment schedule and current market prices, the Registrant is
estimating a production cost similar to that of the Registrant's own mining
operations.

PRODUCTION FORECAST AND SCHEDULE

Based on 75-100 tons per day for a five-day week and 250 working days per year,
an annual production rate of 18,750-25,000 tons or 65,500-87,300 pounds of
recoverable uranium and 506,000-675,000 pounds of recoverable vanadium is
considered by the Registrant to be reasonable.

The Registrant began actual ore production from the Rim Mine in January of 1998
after three months of mine dewatering and general refurbishment.  As of the end
of April 1998, the contractor had produced 990 tons of ore, primarily from
cleanup and development work.

                                 ARIZONA STRIP
OVERVIEW

The Arizona Strip is an area bounded on the north by the Arizona/Utah state
line; on the east by the Colorado River and Marble Canyon; on the West by the
Grand Wash cliffs; and on the south by a mid-point between the city of
Flagstaff and the Grand Canyon. The area encompasses approximately 13,000
square miles. The Arizona Strip is separate and distinct from the Colorado
Plateau District. The two mining districts are located approximately 200 air
miles (310 road miles) apart and have been historically administered as two
separate mining camps.

The Registrant owns a number of permitted mines on standby, partially developed
mines, known deposits and well developed prospects in the Arizona Strip.

Since 1980, when mine development first began at Hack Canyon II, the Arizona
Strip has produced in excess of 19 million pounds of uranium, averaging 0.65%
U(3)O(8) from seven mines, each of which was owned and operated by Energy
Fuels. Of these mines, Hack Canyon I, II, and III and Pigeon are mined out and
have been reclaimed; Hermit is partially reclaimed; Pinenut, Kanab North,
Canyon and Arizona 1 have remaining reserves and have been placed on a standby
basis.

The following table summarizes Energy Fuels' mining history from the Arizona
Strip:

(1)    These deposits have remaining ore reserves

Currently the Registrant has four mines in the Arizona Strip district, all of
which are permitted and have identified mineral reserves remaining. These are
the Kanab North, Pinenut, Arizona 1, and the Canyon. Due to time constraint
only two mines; the Arizona 1 and Canyon, are parts of the S2MS Report.

There are a central office, maintenance shop, and equipment storage facility at
Fredonia, Arizona to service the Arizona Strip mines. Fredonia is located north
of the Grand Canyon and approximately 45 miles from the Arizona 1 Mine. The
Canyon Mine is approximately 80 miles directly south of the Fredonia facility
but due to the Grand Canyon, the mine is over 200 road miles away, accessed via
highway 180.

Ore from both mines can be hauled by truck from the mine site to the White Mesa
Mill. The Arizona 1 Mine is 307 road miles and the Canyon Mine is 316 road
miles from the Mill.

DEVELOPMENT SEQUENCE IN THE ARIZONA STRIP

The ore zones occur in collapsed breccia pipes and range from 1,000 to 1,800
feet below surface with a vertical extent of up to 600 feet thick. Each of the
mines in the Arizona Strip consists of one breccia pipe. The pipes typically
are 200 to 400 feet in diameter. Within this envelope the ore can be at times
massive but often is irregular and discontinuous. Some ore has also been mined
in "ring fractures" just outside the limits of the pipes.

Definition of the ore reserve for these breccia pipe uranium ore bodies is, by
necessity a two stage process. Drilling from the surface provides the initial
data of depth, thickness and grade of ore intercepts determined by downhole
natural gamma logging. Depending on the diameter of the pipe, which ranges from
200 to 400 feet, as many as 40 surface holes, controlled to minimize drift, are
completed, logged and drift surveyed.





                                       26
<PAGE>   27



From this surface drill data, computed proven, probable and possible reserves
are utilized for the decision as to whether or not the sinking of a shaft is
feasible.

A 1,000 to 1,600 foot deep shaft is generally required to access the deposits.
In the case of the Hack Canyon I, II, and III mines, access was obtained
through declines driven from nearby canyons. The average cost for sinking a
shaft is approximately $1,900 per foot.

Once the shaft sinking commences and stations are cut, the second phase of
reserve definition commences. Arrays of long holes and diamond core holes are
completed from the stations cut as the shaft sinking continues to total depth.
From natural gamma logs of the long holes and core holes, integrated and
correlated with the surface drill data, a final proven reserve is computed and
is regarded as the final feasibility study reserve.
In the case of the Arizona 1 Mine where the shaft is completed, the requisite
longhole and core drilling, ore definition is complete. The generated ore
reserve for Arizona 1 is therefore regarded as proven.

The Canyon Mine shaft is not complete, necessitating ore definition from
surface drilling only, yielding reserves characterized as proven, probable and
possible. Based on past experience, Energy Fuels projected that a significant
amount of further reserves would be delineated once underground drilling is
completed.

An Energy Fuels feasibility study dated January 15, 1996 for Canyon Mine
attributed a feasibility reserve of 3,094,000 pounds U(3)O(8) contained in
182,000 ore tons at 0.850% eU(3)O(8). S2MS supports only about 2/3 of this in
its current reserve assessment. However, in the S2MS Report, S2MS notes that a
portion of the Canyon Mine breccia pipe has not been evaluated/drilled from the
surface and underground drilling has not been conducted. S2MS also notes that
Energy Fuels stated that it is realistic to expect that "fracture/ring ore"
will be discovered and that the calculated reserve will be extended to the 3
million pound reserve used in the above cited Energy Fuels feasibility study.


Typically, the life cycle of an Arizona Strip mine is approximately eight
years. The permitting process takes approximately one to two years. The average
mine development and mining phase takes approximately five years, and the
average decommissioning reclamation period is less than one year.

HISTORIC MINING METHODS

The ore zones are quite irregular in shape and can vary from large areas
several hundreds of feet high and wide to small lenses and discontinuous pods.
As a consequence, combinations of mining methods are used to mine the breccia
pipe ore.

Blasthole or slot mining is used to mine the larger zones. The smaller
irregular pods are mined with conventional methods, which include random room
and pillar, shrinkage, and open stoping. Following mining, all the stopes are
left open with no backfilling.

To develop a mine, four or five shaft stations spaced 200 feet apart are
excavated and drifts driven from them to establish the main production levels.
Raises are driven between the levels for ventilation and ore/waste transfer. A
ventilation supply incline is driven around the ore body as a slusher ramp.
Sublevels are driven from the incline at vertical spacings to provide access
for initial stope/slot development and conventional mining.

BACKGROUND GEOLOGY

Breccia pipes are collapse features engendered by cavern dissolution in the
Redwall Limestone, some 3,000 feet below present day surface. Overlying
sediments fracture as the cavern size increases and ultimately collapse forming
a pipe-like structure, which is filled with the rubble of the sediments.
Uranium mineralization occurs in this brecciated rock, forming deposits 200 to
400 feet in diameter, some 600 feet thick at depths up to 1,800 feet.

Uranium ore is hosted by the breccia in a sand, silt, and clay matrix. The
principal uranium mineral, pitchblende, occurs primarily in the matrix, filling
voids between sand grains and replacing rock fragments. Pyrite is the principal
gangue mineral. Calcite and gypsum are common cementing minerals. Copper, lead
and zinc minerals may also be present.





                                       27
<PAGE>   28



Nearly always, the pipe is haloed by alteration or a zone of bleaching
resulting from the partial removal of red iron minerals from formations
surrounding the pipe. "Ring fractures" are often seen at the pipe margins.
These fractures may also be an important host for associated mineralization and
ore reserves.

EXPLORATION POTENTIAL

Since 1980, Energy Fuels developed nine mine projects from which seven mines
produced a total of 19 million pounds of uranium, or approximately 2.7 million
pounds of uranium per mine.

Energy Fuels conducted an extensive exploration program in the Arizona Strip.
Since 1980, Energy Fuels identified in excess of 1,300 breccia pipe targets. Of
these, Energy Fuels drilled at least one hole on 140 breccia pipe targets, of
which 62 were verified to be breccia pipes, and identified mineralization in 42
of these.   Subsequently all of these 42 breccia pipes were acquired by the
Registrant.

Energy Fuels targeted 32 mineralized breccia pipes for further exploration, and
based on past experience believed that these pipes could have a potential
reserve of 40 million pounds of uranium.  S2MS concluded that several up-side
elements exist for the identification of additional reserves in the Arizona
Strip. They were:

1.     Energy Fuels' observation that portions of the Canyon Mine pipe was not
       explored by the surface drilling. These untested areas must be accorded
       potential for hosting additional reserves. That potential could not be
       quantified by S2MS.

2.     The shaft into Arizona 1 was stopped 400 feet short of design depth.
       Thus, planned underground delineation drilling stations designed to test
       that lower portion of the pipe were not available. That portion of
       Arizona 1 must also be accorded potential for hosting additional ore.
       This potential could not be quantified by S2MS.

3.     Energy Fuels' forecast that potentially in excess of 40 million pounds
       U(3)O(8) could exist in several undeveloped deposits in the area. S2MS
       did not review this potential.

S2MS concluded that no specific discernible downside elements were obvious
other than the risks that are a normal part of underground mining ventures.

                                 ARIZONA 1 MINE

LOCATION AND ACCESS

The Arizona 1 Mine is located approximately 45 miles south of Fredonia,
Arizona. Access is by state highway connecting to a well-maintained gravel
road. The project area encompasses 14.7 acres.

MINEABLE RESERVES

The geological resources are 119,500 tons at a grade of 0.545% U(3)O(8). The
mineable reserves accepted by S2MS are lower in tons than the geological
resources, as certain zones below the incremental cutoff grade have been
excluded from the mining plan.

Estimated mineable diluted recoverable ore reserves for Arizona 1 are shown by
S2MS as 80,085 tons grading approximately 0.651% U(3)O(8) resulting in
1,043,149 pounds of U(3)O(8).

PERMITTING

The Arizona 1 Mine is fully permitted for mining.

EXISTING MINE FACILITIES

Site construction for the Arizona 1 Mine began in March 1990. Work was
suspended and the project put on standby status in March 1992. The site is
fully developed to support the resumption of production except for minor
repairs.





                                       28
<PAGE>   29



The shaft has been sunk to a depth of 1,254 feet. The shaft was 400 feet from
the ultimate planned depth when sinking was curtailed.

PRODUCTION FORECAST

Based on 150 tons per day for a five-day week and 250 working days per year, an
annual production rate of 37,500 tons or 449,190 pounds of recoverable uranium
should be achieved.

MINING SCHEDULE

The Registrant has developed a preliminary schedule for development of the
Arizona 1 Mine. Under this schedule, production commences 8.5 months following
the commencement of mobilization. Production continues for 28 months followed
by 6 months of demobilization and reclamation.

CAPITAL COSTS

The total remaining pre-production capital costs for the Arizona 1 Mine have
been estimated by the Registrant to be  approximately $2,100,000.

OPERATING COSTS

The Registrant estimates that its total mining and milling costs will be in the
range of $9.00 - $12.00 per lb. of U(3)O(8) produced.

                                  CANYON MINE

LOCATION AND ACCESS

The Canyon Mine is located 13 miles south of the Grand Canyon, two miles off
highway 180.

MINEABLE RESERVES

The geological resources are 129,000 tons in the proven and probable category
at a grade of 0.801% U(3)O(8). All reserves are estimated from 24 near vertical
holes drilled from the surface.

Mineable, diluted, recoverable ore reserves were estimated by S2MS as 108,168
tons grading approximately 0.902% U(3)O(8) resulting in 1,950,948 pounds of
U(3)O(8).

PERMITTING

The Canyon Mine is permitted to commence mining activities, although an Aquifer
Protection Permit is in the process of being obtained. See "Permitting".

EXISTING MINE FACILITIES

The project site encompasses 17.4 acres with the perimeter impounded by an
earthen berm with riprap stone placed along potential erosion locations. The
site is fully developed with full surface facilities for shaft sinking and
mining.

The shaft was collared to a depth 53 feet. All the facilities required to
resume shaft sinking are in place. Completion of equipping of the headframe is
still required along with modifying or "debugging" the hoist electrics as they
are outdated. The hoist has to be tested and commissioned under load.

PRODUCTION FORECAST

Based on 275 tons per day for a five-day week and 250 working days per year, an
annual production rate of 68,750 tons or 1,190,000 pounds of recoverable
uranium should be achieved.

MINING SCHEDULE

The Registrant has developed a preliminary schedule for development of the
Canyon Mine. Under this schedule, shaft sinking would resume after a three-
month mobilization and equipping period. Shaft sinking would continue for eight
months followed by another 10 months of underground development. Production
would then commence and continue for at least 19 months followed by six months
of demobilization and reclamation.

CAPITAL COSTS

The remaining pre-production costs estimated by the Registrant to bring the
mine into production are approximately $9,450,000

OPERATING COSTS

The Registrant estimates that its total mining and milling costs will be in the
range of $9.00-$12.00 per lb. Of U(3)O(8) produced.

                                  PINENUT MINE
LOCATION AND ACCESS

The Pinenut Mine is located approximately 58 miles from Fredonia, Arizona and
approximately 13 road miles from the Arizona 1 Mine. Access is by state highway
and well-maintained gravel road. The mine is 317 miles from the White Mesa
Mill. The shaft is complete to 1,380 feet and 25,807 tons at 1.02% uranium have
already been mined and 526,350 pounds of uranium produced. Pinenut is
permitted. The current reserve according to the Registrant is:

PERMITTING

The Pinenut Mine is permitted to commence mining activities, although an
Aquifer Protection Permit is in the process of being obtained. See
"Permitting".


                               BULLFROG PROPERTY
LOCATION

The Bullfrog property is located in eastern Garfield County, Utah, 20 miles
north of Bullfrog Basin Marina on Lake Powell, about 40 air miles south of
Hanksville, Utah, and 150 miles from the White Mesa Mill.

HISTORY OF THE PROPERTY

Exxon Minerals conducted reconnaissance in the area in 1974 and 1975 and staked
their first "Bullfrog" claims in 1975 and 1976. A first phase drilling program
in 1977 resulted in the discovery of what is now called the Southwest Deposit.
Additional claims were subsequently staked, and both Exxon's exploration and
pre-development groups continued drilling. Several ore pods were discovered in
the Southwest and Copper bench areas, and ore grade mineralization was also
discovered in the Indian Bench area. Because of declining uranium market
trends, Exxon decided not to proceed with development of the Bullfrog property.
The property was sold to Atlas in July 1982. Between July 1982 and July 1983,
Atlas completed 112 drill holes and delineated the Southwest and Copper Bench
deposits on approximately 100-foot centers. Between July 1983 and March 1984,
Atlas completed an additional 40 hole core drilling program on the Bullfrog
property as well as a 133 rotary drill hole program to delineate the Indian





                                       30
<PAGE>   31



Bench deposit on approximately 200-foot centers. Atlas was unable to sell the
property, and in 1991 returned the claims to Exxon. Thereafter, Energy Fuels
purchased the claims in 1992.

More than 2,200 rotary drill holes have been completed on the Bullfrog
property. Based on this drilling, independent consultants have estimated a
mineral inventory of some 2.6 million tons at an average grade of 0.385%
U(3)O(8) containing 20.1 million pounds U(3)O(8) and 60 million pounds
V(2)O(5). Not the entire prospect has been thoroughly explored, and excellent
potential exists to identify additional reserves.

SUMMARY GEOLOGY AND MINERALIZATION

Geologically, the Bullfrog property is situated on the southeastern flank of
the Henry Basin syncline, which is surrounded by the Monument Uplift to the
southeast, Circle Cliffs Uplift to the southwest and the San Rafael Swell to
the north. Exposed rocks in the Bullfrog area are Jurassic and Cretaceous in
age. Host rocks for the Bullfrog uranium/vanadium deposits are Upper Jurassic
Sandstones of the Salt Wash Member of the Morrison formation. The host
sandstones range from 30 to 40 feet in thickness and are reasonably well
cemented.

The Bullfrog deposits, together with the smaller cluster of deposits discovered
by adjacent claim owners, comprise resources of over 30 million pounds U(3)O(8)
and represent the largest close-spaced cluster of Salt Wash uranium deposits
discovered on the Colorado Plateau.

RESOURCE MODELS

In 1993, Energy Fuels personnel calculated an in-place geological resource of
1,937,065 tons at a grade of 0.334% U(3)O(8) containing 12,923,468 pounds of
U(3)O(8). A higher-grade portion of the deposit contains 1,300,000 tons at a
grade of 0.417% U(3)O(8) or 11 million pounds of U(3)O(8).

                     UNITED STATES IN SITU LEACH PROPERTIES

GENERAL

The Reno Creek Property in Wyoming is amenable to the in-situ leaching ("ISL")
method of mining uranium. The Registrant believes that its Dewey Burdock
Property in South Dakota is also amenable to ISL, however, no pilot plant
testing has been conducted.

THE ISL MINING PROCESS

The ISL mining process, a form of solution mining, differs significantly from
conventional mining techniques.

The ISL process was first tested for the production of uranium in the
mid-1960's and was first applied to a commercial scale project in 1975 in South
Texas. The ISL process had become well established in the South Texas uranium
district by the late 1970's where it was employed in connection with
approximately twenty commercial projects. ISL production has expanded
considerably, and major production centers now exist in Wyoming and Nebraska,
as well as in Texas.

In the ISL process, groundwater fortified with oxygen and other solubilizing
agents is pumped into a permeable ore body causing the uranium contained in the
ore to dissolve. The resulting solution is pumped to the surface where the
uranium is removed from the solution and processed to a dried form of uranium,
which is shipped to conversion facilities for sale to public utilities.

The uranium recovery process consists of a lixiviant circuit, an
elution/precipitation circuit and a drying and packaging process. The lixiviant
circuit flows from the ore body, where the uranium is extracted from the
lixiviant by absorption onto ion exchange resin. The lixiviant is then
refortified and reinjected into the ore body. When the ion exchange column's
resin beads are loaded with uranium, the resin is removed and placed into the
elution circuit where the uranium is flushed with a salt-water solution, which
precipitates the uranium from the beads. This leaves the uranium in slurry,
which is then dried and packaged for shipment as yellowcake.

At the conclusion of mining, the mine site is decommissioned and decontaminated
and the wellfield is restored and reclaimed. Wellfield restoration involves
returning the aquifer to a condition consistent with its pre-mining use and
removing evidences of surface disturbance. The restoration of the wellfield can
be accomplished by flushing the ore zone for a time with native ground water
and/or using reverse osmosis to remove ions, minerals, and salts to provide





                                       31
<PAGE>   32



clean water for reinjection to flush the ore zone. Decommissioning and
decontamination entail decontamination, dismantling, and removal for disposal
or reuse of the structures, equipment, and materials used at the site during
the mining or restoration activities.

COMPARISON OF RESERVES

Most ISL properties have relatively low grades of uranium. The ISL process was
designed to mine low-grade ores out of permeable sands in a cost-effective way.
Given the nature of these ores and of the ISL process, the thickness of the ore
deposits is very important in determining the value of the ore deposit. As a
result, the grade multiplied by the thickness, or "GT", is commonly used to
compare ore deposits that are amenable to the ISL process. Generally ISL
projects in the United States have average GT's of between 1 and 2 (ft %
U(3)O(8)).

                              RENO CREEK PROPERTY

DESCRIPTION, LOCATION AND ACCESS

The Reno Creek Property is a proposed uranium ISL mine project located in the
Powder River Basin of northeastern Wyoming, 47 miles south of Gillette. Access
to the property is by state highway, which cuts through the property.

A 3,613 acre mine permit area currently embraces 5 mining units, 4 of which
would be mined under current plans. The units to be mined are designated mine
units I-IV. Reno South, the fifth mining unit, is a uranium ore body 2 to 4
miles south of the permit area and is included in the ore reserve attributed to
the project but is not yet in the current permit application.

The permit area includes 4 mine units, together with the planned processing
facility and ancillary installations.

EXPLORATION HISTORY

Since the inception of definition drilling at Reno Creek in the 1960's, the
properties have seen a transition of ownership by Union Pacific Railroad
subsidiaries and a joint venture. The majority of drilling was in the 1970's
with little done in the 1980's. Energy Fuels acquired the property in 1992 and
performed development drilling and commercial permitting work.

REGIONAL GEOLOGIC SETTING

Structurally, Reno Creek is on the east flank, near the synclinal axis, of the
Powder River Basin. The Black Hills bound this structural basin on the east and
it is bounded to the south by the Laramie Range and Hartville uplift and the
west by the Big Horn Mountains and Casper Arch.

Stratigraphy of the Powder River Basin is a sedimentary sequence approaching
15,000 feet in thickness along the synclinal axis. Fluvial and lacustrine
Tertiary sandstones, siltstones and shale's with interbedded coal and lignite
seams, compose the upper portions of the column. Downward, Cenozoic, Mesozoic,
and Paleozoic sediments extend to Precambrian basement igneous and metamorphic
rocks.

RESERVES

Uranium at Reno Creek occurs in locally designated ore sand at depths from 300
to 420 feet below surface. The roll fronts in the area are typically low grade
(average less than 0.15% U(3)O(8)) and thick (average up to 17 feet). About
4,000 drill holes are completed and logged on the property. These holes are
generally on lines normal to the roll front, spaced approximately 200 feet
apart with hole spacing thereon 100 feet or greater.

The  Registrant attributes a total reserve to the project of 5,100,000 pounds
U(3)O(8) with average thickness ranging from 14 to 17 feet. Average grades are
from 0.066 to 0.081% U(3)O(8). The Registrant applies a 75% recovery factor,
resulting in 3.8 million pounds recoverable. Average GT values at Reno Creek
range from 1.0 to 1.4.





                                       32
<PAGE>   33



POTENTIAL FOR ADDITIONAL RESERVES

Reno Creek displays significant potential for definition of additional reserves
both within the project area and from properties adjacent or near the project.

Within the project area, potential reserve increases fall into two categories:

1.     A 1988 study prepared by Union Pacific Resources quoted reserves
       attributable to the project of 10.1 million pounds eU(3)O(8). This 1988
       reserve utilized a minimum of 20 feet of hydrologic head above the ore.

       The 10.1 million pound 1988 reserve quotation is 5 million pounds
       eU(3)O(8) greater than the proven and probable reserve now assigned the
       project.

2.     Further reserve additions may come from delineation drilling about and
       between identified reserve blocks. Also, wide spaced drilling has
       identified ore grade intercepts in isolated holes. Additional drilling
       is necessary to explore this potential.

Outside the project area, properties adjacent and nearby host drilled uranium
mineralization and, consequently, the potential for acquisition of additional
reserves also exists. For example, the Registrant attributes about 3.2 million
pounds eU(3)O(8) to a nearby property.

ISL PILOT PLANT

In the 1980's, a field pilot plant was operated on the property. Using
information from the pilot plant, a feasibility study for building and
operating a 4,000 gallon-per-minute ISL capable of producing about 900,000
pounds of yellowcake per year for about eleven years was completed in 1987. In
1995-96, the mine plan and costs were updated. The current plan is a 3,200
gallon-per-minute facility capable of producing 800,000 pounds of yellowcake
per year for about six years.   This plan is for the extraction of only a
portion of the reserve used in the 1989 study.  The recent study shows more
attractive economics by selectively mining the highest quality areas of the
deposit.

The pilot plant demonstrated that an ISL process could mine uranium and that
the ground water can be restored after mining.  RENO CREEK YELLOWCAKE CALCINING
AND PACKING AT WHITE MESA

The Registrant proposes to transport yellowcake slurry by truck to the White
Mesa Mill, where it would be calcined and packaged, so long as it remains cost
effective.

OPERATING AND CAPITAL COSTS

S2MS prepared a prefeasibility cost estimate of $14.68 per pound based on a
recovery of 3,315,000 pounds of uranium with a 65% recovery factor. Capital
development and wellfield costs of $22.5 million are included in the cost
estimates. Management of the Registrant estimates that the costs would be in
the range of $11.00-$14.00 per pound based on a recovery factor of 75%,
resulting in the recovery of 3,825,000 lbs. of uranium.

The capital costs are estimated to be $7 million and include plant, buildings,
restoration equipment, mobile equipment, and permit and license costs. The
purchase of the restoration facilities can be delayed until restoration
activities begin. Total project wellfield and development costs are estimated
to be $15.5 million. However, only the first wellfield needs to be installed
for the project to begin, but replacement wellfields need to be installed
before the first well field is depleted.

Unless altered during the permit review process, a $3 million initial bond will
be required for the project.  The amount of the bond increases annually as
mining progresses, then it begins to decrease later in the mine life as
restoration and reclamation are completed. This cost is not in the operating
cost estimates because the bond is returned at the end of the project when the
project site has been successfully reclaimed.   The project operating cost
estimate includes reclamation and restoration following mining operations

PERMIT LICENSE STATUS

The Reno Creek Property is currently in the permitting process. See

                             DEWEY BURDOCK PROPERTY

LOCATION AND PHYSICAL FEATURES

The project area is located near the Edgemont Mining District in southwest
South Dakota near the Wyoming-South Dakota border. The nearest larger centers
with air connections are Rapid City, South Dakota about 100 miles by road and
Casper, Wyoming, about 175 miles by road. Access to the project area is by an
all-weather gravel road following the course of the railway from Edgemont for
about 30 miles to Burdock and another 10 miles to Dewey.

GEOLOGY

The uranium mineralization at Dewey/Burdock occurs in early Cretaceous
sediments of the Inyan Kara Group which dips to the southwest off the uplifted
Precambrian granitic dome of the Black Hills. The Inyan Kara Group consists of
sandstones, siltstones and mudstones and is divided into the Lakota Formation
and overlying Fall River Formation. The sediments were deposited in a coastal
plain environment with the sandstones following channels so that stratigraphic
levels of the sandstones often change with sands passing into clays.

The deposits are of the typical roll front type with uranium precipitated along
a redox front from solutions percolating through the sandstones. As a result,
the outline of the mineralization follows long, narrow, sinuous courses along
the fronts between the oxidizing and reducing environments.

MINING AND EXPLORATION HISTORY

Uranium mineralization was first discovered in the Edgemont Mining District in
1952, and small quantities of uranium ore were mined in the early 1950's and
shipped to Grand Junction, Colorado for processing. In 1956 a small mill was
established in Edgemont and produced uranium and vanadium from a number of
small operations in the district, mainly open pits, but some production came
from underground workings accessed by adits. When mining finally ceased in the
early 1970's a total of 2.4 million pounds of U(3)O(8) had been produced from
ores averaging 0.14% U(3)O(8).

There was considerable exploration activity for uranium in the district during
the 1970's with the major participants being Wyoming Mineral Corporation and
the Tennessee Valley Authority ("TVA"), though a number of other companies
including Union Carbide, Homestake Mining Company, Federal Resources and Kerr
McGee, were also involved. By 1983 TVA was the sole operator through its
contractor, Silver King Mines, and it continued its exploration efforts in the
Dewey and Burdock areas until 1986 when it relinquished all its land holdings.

In 1981, TVA completed a feasibility study on the Dewey and Burdock areas based
on an underground operation producing 750 tons per day from five shafts (three
at Burdock and two at Dewey). A total mining resource of five million pounds
U(3)O(8) at an average grade of 0.20% U(3)O(8) with a minimum six foot mining
width was estimated.

In 1991 R.B. Smith & Associates, Inc. of Austin, Texas undertook a review and
compilation of all data. This involved an independent resource computation in
addition to a hydrogeological study. This work identified the potential
favorability of these deposits for ISL.  On the basis of this work Energy Fuels
secured property rights covering the Dewey and Burdock projects.

LAND CONTROL

Land control is in the form of a combination of leases with the ranchers in the
area, and unpatented mining claims held by the Registrant.

Any future production of uranium  from most of the project area is subject to a
2% yellowcake royalty to the surface rights owner and a 3% yellowcake royalty
to the mineral rights owners.

RESOURCE ESTIMATE

DATA BASE

The total project resource is 6.66 Million pounds U(3)O(8) with an average GT
grade-thickness of 1.28 (ft.% U(3)O(8)). Additional geologic potential in
excess of 1 million pounds of U(3)O(8) is projected on known trends within the
leased properties, but these trends have not been adequately evaluated by
drilling.

The Dewey/Burdock deposit is being considered as a candidate for ISL mining.
Although the resource computation has been confined to sands below the water
table, little is known concerning the permeability and flow rates of the host
sandstones. Comprehensive tests will have to be conducted before the resource
can be conclusively determined to be amenable to ISL.  Test wells will need to
be drilled to depths of 300 to 550 feet in the Burdock area and 550 to 750 feet
in the Dewey area.

                               MONGOLIA PROPERTY

The Registrant owns a 70% interest and is the managing partner in the Gurvan-
Saihan Joint Venture, which holds significant uranium exploration and resource
properties in Mongolia. The following general information on Mongolia is
derived from publicly available materials, which the Registrant believes to be
accurate.

THE REPUBLIC OF MONGOLIA

The Republic of Mongolia, known from 1924 to 1991 as the Mongolian People's
Republic, is a nation in Central Asia, bounded on the north by Russia and on
the east, south, and west by China. The country has a total area of 1,565,000
square kilometers (604,250 square miles). The capital and largest city of
Mongolia is Ulaanbaatar.

TOPOGRAPHY, CLIMATE AND RESOURCES

The topography of Mongolia consists mainly of a plateau between about 914 and
1,524 meters (about 3,000 and 5,000 feet) in elevation broken by mountain
ranges in the north and west. The Altai Mountains in the southwest rise to
heights above 4,267 meters (14,000 feet). The Gobi Desert covers a wide arid
tract in the central and southeastern areas. The most important rivers are the
Selenge Moron and its tributary, the Orhon Gol, in the north.

Mongolia's climate is harsh, with temperatures ranging between -15degrees and
- -45degrees C (-5degrees and -50degrees F) in winter and 10degrees and 27degrees
C (50degrees and 80degrees F) in summer. Winters are dry, and summer rainfall
seldom exceeds 380 millimeters in the mountains and 125 millimeters in the
desert.

Mongolia contains forests of larch, pine, and cedar in the mountains, but these
are of little economic importance. Fur bearing animals, especially marmot and
squirrel, are abundant, and the country has a well-developed fur industry. Rich
prairie land in the northeast and northwest supports large herds of cattle,
sheep, and goats. Mineral resources such as coal, iron, copper, fluorspar,
gold, uranium, and silver have not been fully exploited.

POPULATION

The population of the Republic of Mongolia (1993 estimate) was 2.2 million,
yielding an overall population density of about 1.4 people per square
kilometer.

The ethnic composition of Mongolia is fairly homogeneous. Khalkha Mongols
constitute more than 75 percent of the population. Other groups are Buryat
Mongols and Kazakhs. The society is about 58 percent urban.

POLITICAL DIVISIONS AND PRINCIPAL CITIES

Mongolia is divided into 18 provinces and 3 independent cities. The independent
cities are Ulaanbaatar, the capital (population, 1992 estimate, 600,900);
Darhan (1991 estimate, 90,000); and Erdenet (1991 estimate, 58,200), a mining
center that developed rapidly in the 1970s.





                                       35
<PAGE>   36



RELIGION AND LANGUAGE

The traditional faith in Mongolia was Buddhist Lamaism, which was suppressed
beginning in 1929. Only one small monastery remains, at Ulaanbaatar. Buddhism
is enjoying a revival since the end of communism in the late 1980's.  The
Mongolian language is one of the Altaic languages.

EDUCATION

Education in Mongolia is compulsory between the ages of 6 and 16. In the late
1980s some 443,000 pupils annually attended about 710 elementary and secondary
schools staffed by approximately 18,400 teachers. Some 22,200 students were
enrolled in vocational and teacher-training schools. About 22,600 students
attended institutions of higher education; some 4,000 of these were enrolled in
the Mongolian State University (1942), in Ulaanbaatar. Other institutions of
higher learning included schools of medicine, agriculture, and military
affairs. While Soviet influence predominated in Mongolia, Russian was taught in
all schools, and several thousand students each year were sent to study in the
Union of Soviet Socialist Republics ("USSR") and eastern European countries.

ECONOMY

The basis of the economy of Mongolia is crop farming and livestock breeding.
Manufacturing is devoted largely to the processing of agricultural and
livestock products.  After the collapse of the socialist system and
disintegration of the former Soviet Union, Mongolia endured a severe decline in
GDP from 1989 to 1993.  The economy has rebounded since 1994 with GDP growth of
6.3% in 1995, 2.6% in 1996, and 3.3% in 1997.  The slower economic growth
reflects a decline of world market prices for copper and cashmere, Mongolia's
two largest exports.

The freeing of fuel and energy prices pushed inflation in 1996 to 59% and
dampened overall consumption.  In 1997, a relatively stable exchange rate was
realized, and inflation was held below 18%.  Economic trends point toward a
sustainable economic growth rate of 5-6% per annum, with inflation falling into
single digits by 1999.

Total foreign trade turnover in 1997 was $861.4 million; exports equaled $418
million, and imports totaled $443.4 million.  Copper and molybdenum
concentrates, fluorspor, goat wool, and cashmere accounted for 66% of exports.

AGRICULTURE

Agricultural production in Mongolia is focused on animal husbandry and crop
farming (wheat, barley, oats, and vegetables). The national livestock herd is
31.3 million animals, comprised of 14.2 million sheep, 10.3 million goats, 3.6
million cattle, 2.9 million horses, and over 355,000 camels.  Mongolia accounts
for more than 25% of world cashmere output and also exports skins, hides, wool,
meat and other animal products.

Crop farming is relatively new in the country and was developed through large
state farms.  The most important crop is wheat, and the maximum arable area is
1,332,000 hectares.  The government has drafted plans to privatize all state
farms and croplands by the end of 1998.

MINERAL RESOURCES

Mongolia has substantial deposits of copper, molybdenum, gold, uranium, lead,
zinc, zeolites, rare earths, ferrous metals, fluorspor, phosphate, and precious
and semi-precious stones.  Several mining operations were developed before 1989
with assistance of the Soviet Union and Eastern European countries, and in
recent years a number of private mining operations have begun.    Due to
isolation from international trading systems and lack of infrastructure, many
mining prospects remain undeveloped.   In recent years, gold production has
emerged as one of the most dynamic sectors of the Mongolian economy.  Gold
production has grown seven-fold since 1990 and reached 8 metric tons (257,000
oz.) in 1997.

The Mongolian and Russian joint venture Erdenet has been operating since 1981
with an annual capacity of 20 million tons of copper ore; this capacity is
being expanded to 24 million tons of ore per year.  Recoverable metal is
estimated to be 7,556,000 tons of copper and 43,600 tons of molybdenum in ore
averaging 0.53% copper and 0.018% molybdenum.

Mongolia has substantial proven reserves of coal.  Coal is the major source of
energy production and is likely to remain so.  Mongolia's coal reserves are
estimated at about 100 billion tons, 20% in hard coal deposits, and 80% in





                                       36
<PAGE>   37



lignite deposits.  In 1997, domestic coal production totaled about 5 million
metric tons, the majority of which was consumed for domestic needs.

Mongolia has one operable oil field in the Gobi region, and initial results of
petroleum exploration in eastern and western Mongolia, carried out by companies
from the U.S., Europe, China, and Russia, appear to be promising.

ENERGY

The Central Energy System of Mongolia has four coal-fired power plants (two in
Ulaanbaatar, one in Darkhan, one in Erdenet) with a total capacity of 690MW.
At peak demand times, additional power is imported from Russia.  Power for
small towns in outlying areas is provided primarily by diesel generators or
small coal-fired plants.

CURRENCY AND FOREIGN TRADE

The currency of Mongolia is the tughrik (togrog), which consists of 100 mongo
(820 tughriks equal US$1.00; 1998).

Most of Mongolia's trade is with the countries that made up the former USSR and
other former Soviet-bloc countries. Since the early 1990s, Mongolia has made
efforts to expand trade with other countries. Principal exports in the late
1980s were minerals, cattle, meat products, wool, and consumer items. Imports
consisted mainly of machinery and transport equipment, consumer goods, and
industrial raw materials.

TRANSPORTATION AND COMMUNICATIONS

Mongolia is served by the Trans-Mongolian Railway, which connects Ulaanbaatar
with Russia and China. Truck services operate throughout the country. Steamer
services operate on the Selenge River and a tug and barge service on Lake
Hovsgol. Air service connects Ulaanbaatar with Moscow, Beijing, Seoul, and
cities in Central Asia. Domestic services are provided by Mongolian Civil Air
Transport.

In the late 1980s, Mongolia was served by about 55,000 telephones, 212,000
radio receivers, and 111,000 television sets. The country has nine national
newspapers. Unen, a daily newspaper published in Ulaanbaatar, is the most
widely read, with a daily circulation of about 170,000.

GOVERNMENT AND JUDICIARY

Under Mongolia's 1960 constitution, the supreme organ of state power was the
People's Great Hural ("Khural"), a 430-member assembly that usually met twice a
year. The Mongolian People's Revolutionary (Communist) party ("MPRP") was the
sole legal party until 1990, when the constitution was amended to allow
opposition parties, to institute a presidential system of government, and to
add a 53-member standing legislature, the Small Hural. In January 1992, a new
constitution was adopted. By this constitution, the legislative power of the
republic resides in the 76-member Great Hural; the delegates of the Great Hural
are chosen for 4-year terms through free elections. The president is head of
state, and is also elected to a four-year term.

Mongolia is divided into 18 provinces, or aimags, which are subdivided into
districts, or somons. Local centers of power are hurals, or assemblies, of
working people's deputies. Ulaanbaatar, Darhan, and Erdenet are separate
administrative units, governed by city hurals.

In Mongolia, the Supreme Court, the city court of Ulaanbaatar, 18 provincial
courts, and local district courts administer justice. The assemblies at each
political level elect members of the courts.

HISTORY

Modern history of Mongolia begins with the rise of the great Mongol Empire at
the beginning of the 13th Century under Genghis (Chinggis) Khan.  By 1280 the
Mongol's ruled from Peking to the Adriatic and from Siberia to Persia and the
northern border of India.  Kublai Khan, grandson of Genghis, founded the Yuan
dynasty in China in 1271.  The Manchu Empire subjugated Mongolia in 1691.  The
period of Manchur colonialism, which lasted for 220 years, was a grim time in
Mongolian history.

After the Chinese revolution of 1911, Mongolia declared its independence from
China, but the Living Buddha continued to rule. In 1920 a military force
supplied and financed by Japan and led by a Russian anti-Bolshevik general,
Baron Roman Nikolaus von Ungern-Sternberg, took the capital, Urga, and set up a
puppet government. In





                                       37
<PAGE>   38



1921 the Mongolian People's Revolutionary party, formed by Soviet-trained
Mongols, established an independent Provisional People's Government and, with
aid from the USSR, defeated Ungern-Sternberg and his supporters. The theocratic
monarchy, its powers limited, was retained by the provisional government until
1924, when the last Living Buddha died. At that time, the Mongolian People's
Republic, modeled on Soviet lines, was founded, but China did not recognize its
independence until 1946. After the Communists won power in China in 1949, trade
and cultural relations were established between the two nations, but the
Sino-Soviet split in the late 1950s curtailed these relations. A Sino-Mongolian
border treaty was signed in 1962, but Mongolia maintained its closest ties with
the USSR, which in 1961 sponsored its membership in the United Nations. The two
countries signed a treaty of friendship, trade, and mutual assistance in 1966,
renewed in 1986. In the 1980s, the USSR was Mongolia's leading trade partner
and aid donor; about 65,000 Soviet troops were stationed in Mongolia.

In March 1990, Punsalmaagiyn Ochirbat, former foreign trade minister, became
president, inaugurating a period of political and economic liberalization.
After the new constitution was adopted in January 1992, the reconstituted
Mongolian People's Revolutionary party swept the parliamentary elections in
June of that year. In January 1993, President Ochirbat and the Russian
President Boris Yeltsin signed another treaty of friendship and cooperation, to
replace the treaty of 1986. In June 1993, President Ochirbat was re-elected.
In 1996, the Social Democratic Party won a majority of seats in the Mongolian
Parliament.  In 1997, N. Bagabondi defeated President Ochirbat.

MONGOLIA PROPERTY

OWNERSHIP

The joint venture company, Gurvan-Saihan BBHK, was formed in Mongolia in
January 1994 by Energy Fuels, Geologorazvedka ("GRZ"), a unit of the Russian
Ministry of Geology, and URAN, a state enterprise under the Ministry of Energy,
Geology and Mining of Mongolia. Energy Fuels was required to spend $4 million
to become fully vested, at which time it held 70% of the joint venture company,
with GRZ and URAN each holding 15%. The $4 million expenditure requirement was
fulfilled in April 1997; The Registrant continues to fund 100% of Venture
activities.  The disproportionate funding is recoupable out of the carried
partners' shares of proceeds from future uranium production. A royalty in the
amount of 4% is payable to the Mongolian government.

LOCATION AND PHYSICAL FEATURES

The Mongolian joint venture is comprised of five separate concession blocks, in
the original grant by the Mongolian government that cover a total area of
12,100 square kilometers in central eastern Mongolia.  Based on encouraging
exploration results in the 1996 and 1997 field seasons, the joint venture added
4365 square kilometers in eight additional parcels in early 1998.

The East Gobi region of Mongolia is a plateau at 3,000 to 3,500 feet above sea
level characterized by low hills and gently rolling topography. The climate is
harsh with typical extremes of an intercontinental climate similar to the
southern prairies of Canada and northern plains of the United States. The
region is semi-arid with numerous dry lake beds and salt marshes and no
permanent rivers.

The Choir concession, where most of the work has been undertaken prior to 1997,
is on the Trans-Mongolian Railway about 250 kilometers southeast of Ulaanbaatar
and about 1,100 kilometers from Beijing. A network of numerous unpaved trails
connects most centers, and truck or 4x4 vehicles following tracks or driving
cross-country can reach the various concession areas.   In 1997, the Joint
venture focused the majority of its effort's on the Hairhan area as the result
of encouraging initial exploration in 1996.

EXPLORATION HISTORY

Uranium prospecting was started by the Russians in 1955 and resulted in the
discovery of several showings in the Choir Depression. Detailed work, which
began in 1970 with an airborne gamma-ray spectrometer survey and ground follow
up, resulted in the identification of the Haraat deposit in the Choir
Depression.

In 1988 and 1989 a major drilling program was undertaken in the Choir
Depression with a series of drill hole fences across the full 10 to 20
kilometers width of the depression. Fence spacings ranged from 8 to 12
kilometers with hole spacings at 100 to 800 meters. A total of 47,000 meters of
drilling was completed in over 1,000 holes ranging in depth from 20 to 400
meters. The vast majority of the drilling was shallow down to 40 metres,
testing the shallow

mineralization in the Upper Cretaceous with efforts concentrated on defining
the mineralization at Haraat. A few deeper holes were drilled to test the
potential of the basin at depth.

Extensive drilling resumed in 1994 with the formation of the Gurvan-Saihan
Joint Venture, and delineation drilling was undertaken at Haraat on a 200
metres x 100 metres grid with some closer spacing at 100 metres x 50 metres.
Preliminary field ISL studies were also conducted at Haraat in 1994.

In 1995 modern probing equipment using digital recording was sent to Mongolia
from the United States and has been used on probing of all holes since then.
This allows for a more efficient use of data, and also allows for
discrimination of individual lithologic units.

In 1996 the Joint Venture focused its efforts on the Choir Depression and in
the Haraat area in particular.  An ISL Pilot test using acid solution was run
on ore horizons both above and below the water table (leaching above the water
table is a promising technology that requires further refinement).  The 1996
pilot testing demonstrated that the deposits at Haraat, both above and below
the water table, are suitable for ISL.  Additional testing and research is
needed to refine the leach chemistry.
The total exploration-drilling program in 1996 was in excess of 33,000 meters,
with the majority of the work in the Choir Depression.  Based on detailed
radiometric surveys, initial reconnaissance drilling was conducted in 1996 in
both the Hairhan and the Gurvan Saihan Depressions.  Ore-grade discoveries were
made in both basins, and the discovery hole at Hairhan was the thickest,
highest-grade hole drilled to date in the Mongolia venture.

The 1996 results led to a major expansion of exploration drilling in 1997,
directed primarily to the discovery area at Hairhan.  Over 34,000 meters were
drilled at Hairhan in 1997, and resources in excess of 10-million lbs. uranium
have been identified.  The remainder of the 1997 drilling was conducted in the
Choir Depression to expand the resources below the water table in the region of
the Haraat deposit.  Initial reconnaissance drilling was also conducted in the
Ulziit Depression in 1997, and this area also appears to be highly prospective
for uranium deposits.

GEOLOGY

Uranium exploration is focused on large depression areas filled with Cretaceous
sediments and flanked by Proterozoic schists, gneisses and limestones as well
as Permian acid volcanics, Palaeozoic granites and Mesozoic leucogranites and
volcanics. The Lower Cretaceous, which is up to 1,500 metres thick, is
comprised of two facies: (1) low-sorted gravels, conglomerates and sandstones,
and (2) lake sediments (clays, argillaceous sandstones) and brown coals. The
Upper Cretaceous is five to 40 metres thick, consists largely of sand and
gravel formations cemented by limonite-goethite, and is confined to small areas
near the centres and margins of the major depressions. The dips are flat, but
may steepen to 5degrees to 10degrees near margins. There is some block
faulting, and dips may increase to 70degrees to 80degrees against faults, but
there is generally little structural disturbance.

The uranium mineralization is found in paleo channels and alluvial/fluvial
systems and is thought to have been deposited from solutions percolating
through the porous sandstones and precipitating uranium at reducing interfaces
with organic detritus. The Russian geologists consider the granites as the most
likely sources, and consequently rate the areas of the depressions flanked by
granitic rocks as the most prospective. The main uranium minerals in the
reducing environment below the water table are uraninite and coffinite. Above
the water table, a number of different secondary minerals have been identified
and include autunite, torbernite, bergenite and phosphuranylite. Geochemical
studies show that small amounts of RE, rhenium and selenium accompany the
uranium mineralization.

THE HARAAT DEPOSIT

Two concentrations of mineralization have been identified at Haraat, referred
to as the N1 and N2 ore bodies.

Geological resource estimates were prepared by the Russian geological team for
the areas of expanded drilling in 1997 in the Haraat area. The estimation
methodology, utilizing a 0.01% U cutoff, is basically a block or polygonal
technique wherein ore-being coefficient and average thickness and grade values
are determined for each mineralized area.  The geological resources in the most
heavily investigated areas, the N-1 and N-2 deposits, were calculated by a
joint American-Russian team in early 1997; the combined current proven,
probable and possible geological resource total for the Haraat area deposits is
presented in the following table:

THE HAIRHAN DEPOSIT

By the end of 1996 exploration season, a 23km anomalous trend, based on
radiometric surveys, was delineated in the Hairhan depression.  A major
exploration and delineation program in 1997 followed the initial reconnaissance
drilling which led to the Hairhan uranium discovery. A 6.5km mineralized trend
was discovered with drilling on sections 800 and 1600 meters apart.  The
richest portion of the deposit is an area about 1600m by 1500m and has not yet
been fully investigated by drilling.

A total of 495 holes and test wells have been drilled at Hairhan through the
end of the 1997 field season.  The majority of the holes are in the main block
(1000m by 1500m); which has been drilled on 100mx50m spacing to support
calculation of probable geological resources.

The Hairhan deposit is hosted in sandy sediments deposited in a fault graben,
which focused the deposition of a sequence of alternating sands, siltstones,
clays, and carbonaceous layers.  The graben aligns with a structural valley in
the nearby granitic highlands.  Erosion, weathering, and leaching of the
granites and the derived sediments formed uranium deposits in multiple layers.
The ore deposition is related to reduction-oxidation interfaces.  The ore
ranges from 10m to at least 100 m deep, with as many as four stacked horizons
in some locations.

In addition to resource delineation drilling in 1997, core holes were drilled
to obtain rock samples for testing, and hydrogeological test wells were
installed to evaluate aquifer properties.  The water table is shallow at
Hairhan, and all mineralization of interest is below the water table.  The
Hairhan deposit exhibits favorable characteristics for ISL.

Proven and probable geological resources have been calculated at 0.024%
U(3)O(8) cutoff for the area of detail drilling at Hairhan.

GURVAN-SAIHAN JOINT VENTURE PROJECT -- IN-SITU MINING CONSIDERATIONS

In Situ Leach is viewed as the most viable technique for exploitation of the
uranium deposits in Mongolia.  Not only does ISL enjoy the benefits of lower
capital and front-end development expenditures than conventional open pit or
underground operations, it also often has more attractive operating costs.
Another major appeal of ISL is the minimal surface and related environmental
impacts incurred in comparison with conventional mining and milling operations.

The deposits at Haraat and at Hairhan are suitable for ISL.  Pilot tests have
been run at Haraat, and testing is planned to begin in 1998 at Hairhan.
Preliminary field data from core samples and hydrogeological tests indicate
that the ore is amenable to acid leach and that the hydrology is acceptable.

The substantially richer deposit at Hairhan, coupled with the fact that the ore
is below the water table, has elevated Hairhan ahead of Haraat as a potential
commercial project.  Although laboratory and field data are encouraging for
ISL, full scale testing must be successfully conducted to confirm the operating
parameters and costs for an ISL mine in Mongolia.

Other Areas

Work in other concession areas at the present stage has only been of a
reconnaissance nature involving prospecting and some car-borne scintillometer
surveys, with initial exploratory drilling at Gurvan-Saihan and Hairhan in 1996
and in the Ulziit Depression in 1997.  A total of seven widely spaced fences
over an 18 km long trend were drilled at Gurvan-Saihan with mineralization
intersected in six of the seven fences.  The best results was 0.102% U over 1.3
meters.  Examples of other intersections are 0.062% U over 1.2 meters, 0.06% U
over 1.6 meters, 0.04% U over 1.9 meters, 0.036% U over 4.8 meters, 0.024% U
over 1.1 meters, and 0.018% U over 4.0 meters.

In the Ulziit Depression, reconnaissance work between 1958 to 1963 located five
uranium occurrences and 10 radiometric anomalies.  The Russian geologists
consider that this depression is similar to the Choir Depression and has
excellent potential.  Initial exploration drilling was conducted in 1997 in the
Ulziit area; based on encouraging geologic results, an expanded exploration
drilling program is planned for 1998.

                         TOLL MILLING AND PURCHASED ORE

The White Mesa Mill is a fully permitted uranium Mill in the United States with
a vanadium and other co-products recovery circuit that is strategically located
in southeast Utah near the Colorado Plateau District and the Arizona Strip.

It is unlikely that new Mills will be constructed at current prices of uranium.
The White Mesa Mill cost $40 million to construct in 1980.  With inflation,
more stringent permitting requirements, and the lack of suitable sites, the
cost of constructing a facility such as the White Mesa Mill, if possible, would
be considerably more than that amount.

Historically, Energy Fuels had toll milled ore from other uranium and
uranium/vanadium mines and had purchased ore from independent mines which it
then processed through the White Mesa Mill.

Commencing in 1978, in anticipation of the construction of the White Mesa Mill,
Energy Fuels instituted a buying program throughout the Colorado Plateau
District which procured approximately 1.8 million tons of ore from 177
different "independent" mine operators and five large scale mines.  Energy
fuels constructed two ore buying/sample facilities and orchestrated a $50
million yearly ore purchase program which enabled them to accumulate a two year
Mill-feed inventory before the White Mesa Mill was completed.  This was at a
time when Energy Fuels did not have any operating mines that could feed the
Mill.

The Registrant has instituted a Purchase Ore Program to supplement the feed to
the White Mesa Mill from its mines in the Colorado Plateau District and Arizona
Strip. The Registrant had been contacted by a number of large corporate holders
of mines and reserves in the Colorado Plateau and Arizona Strip areas to
discuss arrangements for tolling their ore through the White Mesa Mill.  The
Registrant intends to pursue these negotiations and seek out additional toll
milling opportunities in the area. In addition, the Registrant believes that
significant tons of ore could be purchased at a profit from independent mines
in the Colorado Plateau area.  The amount of tolled and purchased ore that will
be available will vary with the prices of uranium and vanadium.

                                ALTERNATE FEEDS

In addition to processing conventional ores as explained above, the Mill also
has the capability to process Alternate Feeds and recover uranium at costs
below the costs of producing uranium by either conventional or in situ methods.
These Alternate Feeds can generally be thought of as ores or residues from
other processing facilities that contain uranium in quantities that are either
uneconomic to recover or cannot be recovered at these other facilities.  As
such, they become a costly disposal issue for the owner, not to mention a
wasted resource.  However, the Registrant has demonstrated the capability to
"recycle" these Alternate Feeds through the Mill, recover whatever uranium is
present, and dispose of the remaining waste in the Registrant's tailings cells.
The mill's co-product recovery circuit also allows the Registrant to recover
other valuable materials such as tantalum, niobium, scandium, and zirconium
that might be present in these alternate feeds.

The Registrant has entered into and processed material under four separate
alternate feed agreements to date and is currently negotiating other alternate
feed arrangements at this time.

                                 ENVIRONMENTAL

An environmental overview of Energy Fuels' mine sites in Colorado, Utah and
Arizona and the White Mesa Mill was initially conducted by Simons Environmental
Group ("Simons") of Vancouver, BC Canada, in March 1996.

Based on this review, Simons concluded that overall Energy Fuels appeared
environmentally well managed.  Energy Fuels was named as a Potentially
Responsible Party ("PRP") on a CERCLA (Superfund) Site for approximately
$187,000.  This was a result of an environmental incident at the Colorado
School of Mines in 1990, involving ore which originated from Energy Fuels in
1979 for a processing trial, and is unrelated to the Registrant or any of the
Registrant's properties or operations.

Simons concluded that the mine sites are unlikely to represent a major
immediate environmental liability.  The Colorado Plateau mines sites may
require some minor erosion control, housekeeping, and storm water management.
The Arizona Strip mine sites appear environmentally well managed. A tailings
cell liner at the White Mesa Mill will require repair or replacement prior to
commencement of its use. See "White Mesa Mill".





                                       42
<PAGE>   43



In January 1997, the Registrant engaged Simons to update its prior
environmental review of the Energy Fuels Assets, and in particular to complete
Phase I Environmental Site Assessments, according to ASTM standards, on the
Sunday Mine Complex, the Deer Creek Mine Complex, the White Mesa Mill, the
Arizona 1 Mine, the Pinenut Mine, the Kanab North Mine, the Canyon Mine and the
Reno Creek Property. These assessments involved a review of Federal and State
records, interviews with site personnel, a review of relevant files, site
reconnaissance, and interviews with local regulators. In its Phase I
Environmental Site Assessments on these properties, Simons concluded that no
recognized environmental conditions existed on any of those properties.

                                   PERMITTING

The permitting status of the various mines is set out below.

ARIZONA 1 MINE

The Arizona 1 Mine is fully permitted for mining.

SUNDAY MINE COMPLEX

The Sunday Mine Complex is fully permitted for its mining activities.  Recent
changes in the laws of Colorado could give rise to additional future permitting
requirements.

In recent years, the State of Colorado passed a law that provides that the
Colorado Division of Minerals and Geology ("DMG") can determine that a mine is
a Designated Mining Operation (a "DMO") if it is a mining operation at which
"toxic or acidic chemicals used in extractive metallurgical processing are
present on site or acid- or toxic- forming materials will be exposed or
disturbed as a result of mining operations". If a mine is determined to be a
DMO, the most significant result is the requirement that it submit an
Environmental Protection Plan (an "EPP"). The EPP must identify the methods the
operator will utilize for the protection of human health, wildlife, property
and the environment from the potential toxic- or acid-forming material or acid
mine drainage associated with the operations. The EPP must be submitted to the
DMG for review, and after a public hearing, a decision must be made within 120
days of the submission of a complete application, unless the application is
considered to be complicated, which would extend the deadline to 180 days.

In 1995, DMG notified Energy Fuels that they believed that the Sunday Mine
Complex was a DMO, because of the potential that storm water could come in
contact with the low grade waste rock on site. Energy Fuels disputed this
assertion. Testing was performed on the waste rock. In November 1996, the DMG
advised Energy Fuels that the test results of the average uranium content of
the waste dumps at the mine sites satisfied the DMG that the Sunday Mine
Complex is not a DMO. However, the DMG also advised that its determination
could change if site conditions or circumstances change. Therefore, if mining
activities are re-initiated at these mines, the DMG reserved the right to
submit a new notice of determination, which may require additional
environmental review. As of this filing date, the Registrant has not been
notified of any additional permitting requirements relating to its current
mining activities at the Sunday Mine Complex.

CANYON MINE

The Canyon Mine is the first mine to be permitted in the portion of the Arizona
Strip that is south of the Grand Canyon. The Canyon Mine is located on federal
lands administered by the United States Forest Service and is near the southern
rim of the Grand Canyon. The plan of operations submitted by Energy Fuels in
1984 for development and operation of the mine generated significant public
comment resulting in the invitation of an environmental impact statement
process by the United States Forest Service. The United States Forest Service
for the State of Arizona approved the plan of Energy Fuels and issued all
necessary federal and state permits and approvals. The Havasupai Indian Tribe
and others filed appeals. The United States Forest Service for the State of
Arizona and Energy Fuels prevailed on all appeals. During the permitting
process, Energy Fuels constructed all the necessary service facilities at the
mine site. Energy Fuels agreed with the United States Forest Service not to
implement underground development during the environmental impact statement
process. Energy Fuels did not resume underground development at the mine site
when the appeals were determined due to the decrease in uranium prices at that
time.

In 1992, the State of Arizona updated its laws relating to groundwater issues,
requiring that an Aquifer Protection Permit be obtained.  It is not expected
that there will be any problems of any significance in obtaining this permit,
and the Registrant is currently permitted to commence mining at the Canyon Mine
during submittal, review and update to the Aquifer Protection Permit.

PINENUT AND KANAB NORTH MINES

As with the Canyon Mine, these mines both require that an Aquifer Protection
Permit be obtained. Energy Fuels did not expect that there will be any problems
of any significance in obtaining this permit and is currently permitted to
commence mining at each of these mines during submittal, review and update to
these Aquifer Protection Permits.

RENO CREEK PROPERTY

Energy Fuels filed applications for commercial operating licenses and permits
to mine the Reno Creek by ISL methods.  In January 1995, the Wyoming Department
of Environmental Quality declared the Reno Creek Mine Permit application
complete, and the applications are now in the technical review phase.

The Registrant re-initiated commercial permitting late in 1997.  Applications
are under review for a Mine Permit, Class I Waste Disposal Well, Wastewater
Disposal System, NPDES Discharge Permit, and related subsidiary permits from
the State of Wyoming.  In additional the U.S. Nuclear Regulatory Commission is
processing the Registrant's application for a Source Material License.


                                  RECLAMATION

The Registrant is responsible for the environmental and reclamation obligations
relating to all of its existing mines and assets, as well as for all
reclamation and environmental obligations associated with all mined out,
inactive, reclaimed or partially reclaimed mines and properties acquired from
Energy Fuels on the Acquisition.

The total amount of the estimated reclamation liability is approximately
$13,265,000 with cash of approximately $8 million securing the liability. All
of the Registrant's mines and the White Mesa Mill were permitted through either
state or federal authorities. As a part of permit requirements, reclamation and
decommissioning bonds are in place to cover the estimated cost of final project
closures. The major cost is for closure of the White Mesa Mill and tailings
cells which is estimated at $11.5 million.  The Registrant has posted a
reclamation's bond  to the NRC for this amount.

                             SWISS ROYALTY INTEREST

As consideration for funding a large part of the cost of construction of the
White Mesa Mill, the Swiss Utilities acquired a 40% limited partnership
interest in all of Energy Fuels' properties in the United States. This limited
partnership interest did not apply to the Mongolia Property.

In 1995, after commencement of the bankruptcy proceedings against Energy Fuels,
the Swiss Utilities agreed to fund the milling of approximately 200,000 tons of
stockpiled ore, the proceeds of which were used to repay this funding provided
by the Swiss Utilities, and to provide working capital to the bankrupt estates.
As part of this financing and Mill run, Energy Fuels and the Swiss Utilities
agreed to convert the Swiss Utilities' 40% limited partnership interest in the
United States properties, into a royalty (the "Swiss Royalty") of 9% of all
uranium and 5% of vanadium and all other minerals produced from the United
States properties owned by Energy Fuels at the time that the royalty was
granted. The Swiss Royalty will apply to all production from the Colorado
Plateau District properties and Arizona Strip properties acquired on the
Acquisition, as well as the Reno Creek Property, a portion of the Dewey Burdock
Property and the Bull Frog Property. The Swiss Royalty Interest does not apply
to the Mongolia Property, nor to any tolled ore, or purchased ore from third
parties, or Alternate Feeds that are processed in the White Mesa Mill, nor to
any properties acquired by Energy Fuels after the date that the Swiss Royalty
Interest was granted.

Subsequent to the Acquisition, the Registrant has amended the Swiss Royalty
amount to 4.5% of all uranium and 2.5% of vanadium for the period from January
1, 1998 to December 31, 2000.  The Registrant will make an advance royalty
payment of $250,000 per year, which is fully recoupable annually against any
royalties for the applicable calendar year.  Subsequent to December 31, 2000,
the royalty reverts to its original terms.

                         INTERCOMPANY ROYALTY INTEREST

The Registrant has purchased  production royalties from International Uranium
Holdings Corporation and its 100% owned subsidiaries for a total purchase price
of approximately $25 million.  This amount will be repaid from future
production.
                              THE URANIUM INDUSTRY

OVERVIEW

The only significant commercial use for uranium is to fuel nuclear power plants
for the generation of electricity. According to the Energy Information
Administration of the United States Department of Energy (the "EIA"), nuclear
plants generated approximately 17% of the world's electricity beginning 1997.
According to the EIA, nuclear electric generating capacity is expected to grow
modestly between now and the year 2000, at a rate somewhat below that for the
total market for electricity, primarily as a result of new reactor construction
outside the United States.

The major stages in the production of nuclear fuel are exploration, mining and
milling, including in situ leach, conversion, enrichment for light water
reactors, and fuel fabrication. Once a uranium deposit is discovered and
reserves delineated, uranium ore is mined and partially refined at a nearby
Mill to produce uranium concentrates. These uranium concentrates are generally
in the form of U(3)O(8), or "Yellowcake" as it is referred to in the industry.
Mining companies usually sell uranium to utilities around the world in the form
of U(3)O(8) contained in uranium concentrates. Market participants, such as
utilities, then contract with converters, enrichers, and fuel fabricators to
produce the required reactor fuel.

URANIUM SUPPLY AND DEMAND

The installed Western World nuclear electric generating capacity is projected
to increase from 351.0 net GWe in 1997 to 390.5 GWe by 2010 representing an 11%
increase. The forecasts for installed Western World electric generating
capacity for 2000 and 2010 are based on many factors, including the utilities'
announced plans for nuclear capacity up to the year 2010 as well as government
announcements from countries operating, building or contemplating building
nuclear generators. In addition, the EIA made many country specific assumptions
about whether the utilities in each country would follow current schedules for
start-ups or shut-downs of generators and whether government pronouncements
were credible and would be carried through to fruition. No assurances can be
given that such assumptions are correct or that the schedules for expected
start-ups and shut-downs of nuclear generators will not be changed at any time
by utilities. As a result, the EIA's forecasts are subject to many risks and
uncertainties and, therefore, no assurances can be given that actual results
will not differ materially from such forecasts.

At the end of 1996, the United States led the world in nuclear capacity (100.7
GWe), followed by France (59.9 GWe), Japan (42.4 GWe), Germany (22.3 GWe),
Russia (19.8 GWe), Canada (14.9 GWe), Ukraine (13.8 GWe), and the United
Kingdom (12.9 GWe).  Combined, these eight countries accounted for 82 percent
of the world's capacity for generating electricity. The Far East, with 33
scheduled units totaling more than 30.9 Gwe, lead world nuclear construction
programs. A total of 18 countries have been identified as having nuclear units
in the construction pipeline.

The demand for U(3)O(8) is directly linked to the level of electricity
generated by nuclear power plants. According to the Uranium Institute ("UI"),
annual Western World uranium fuel consumption has increased from approximately
56 million pounds U(3)O(8) in 1980 to about 144 million pounds U(3)O(8) in
1997. The UI estimates that annual uranium fuel consumption in the Western
World will reach 153 million pounds U(3)O(8) in 2001. Demand could be increased
by trends toward increased plant operating capacities or reduced by premature
closing of nuclear power plants.

Because of historically high prices for uranium concentrates and overly
optimistic expectations for new nuclear reactor construction, Western World
uranium production exceeded consumption in the late 1970s and early 1980s. This
led to a large build-up in inventories, which was exacerbated by new reactor
construction delays or cancellations. The resulting large inventory surplus
acted to depress the market and prices; and resulted in a dramatic
restructuring of the uranium production industry. There have been significant
reductions in mine production levels as higher cost producers have closed
operations on completion of high-priced sales contracts. For example, mine
production in the United States was reported by the UI to have declined from
43.7 million pounds U(3)O(8) in 1980 to about 5.6 million pounds in 1997.





                                       45
<PAGE>   46



Consequently, Western World uranium consumption has exceeded Western World
uranium production since 1985. For example, at the start of 1997, the Uranium
Institute estimated that consumption exceeded production by approximately 63
million pounds U(3)O(8) or 81% of Western World production of 77 million pounds
U(3)O(8). The Registrant believes that for the last several years this
production shortfall has been filled by, in order of magnitude, (i) the
drawdown of excess inventories held by utilities and governments (ii) supplies
from certain CIS republics primarily Russia, Uzbekistan and Kazakhstan , and
(iii) to a lesser extent, supplies from Eastern Europe and mainland China.

NUEXCO TRADING CORPORATION BANKRUPTCY

On February 23, 1995 Nuexco, an affiliate of Energy Fuels, and Energy Fuels
filed for bankruptcy protection under Chapter 11 of the United States
Bankruptcy Code. See "Energy Fuels -- Bankruptcy of Oren Benton and Nuexco".
The total liabilities owed creditors of Nuexco are reported to be in excess of
$500 million. Although Nuexco continued to operate after its bankruptcy filing,
short-term defaults on some deliveries occurred, and several utilities entered
the spot market in 1995 to cover these defaults. The Registrant believes that
the resulting shortfall contributed to the increases in spot prices during 1995
and 1996.

CIS URANIUM SUPPLY

During the period 1991 to 1994, the CIS republics aggressively sold substantial
quantities of uranium into the Western World market. United States and European
government responses to these sales have limited the access of CIS producers to
these markets. In the United States, an ad hoc group of the Uranium Producers
of America ("UPA") and others filed an anti-dumping suit ("CIS Anti-dumping
Suit") against some republics of the former Soviet Union. The resulting
settlement was effected by suspension agreements (each, a "Suspension
Agreement") signed with six CIS republics (Russia, Kazakhstan, Uzbekistan,
Kyrgyzstan Ukraine and Tajikistan) in October 1992, which applied price related
quotas to CIS uranium permitted to be imported into the United States. If the
United States market price for U(3)O(8), as determined by the United States
Department of Commerce (the "DOC") was below $13.00 per pound, CIS uranium
deliveries into the United States were to be limited to those existing under
certain long term contracts entered into before March 5, 1992. At a price
between $13.00 and $21.00 per pound, the amount that could be imported into the
United States was based upon a sliding scale and at $21.00 per pound and above,
there were no limits on the amount that could be sold into the United States.

The fact that the DOC price failed to reach $13.00 in 1993 caused the DOC and
the Russian Ministry of Atomic Energy to sign an amendment to the Russian
Suspension Agreement in March 1994. The amendment allows for up to 43 million
pounds of Russian U(3)O(8) to be imported into the United States over the 10
years beginning March 1994, but only if it is matched with an equal volume of
new United States production. In total, the matched volumes could, based on
current consumption rates, account for up to 20% of the supply to the United
States market.

In March and October of 1995, the DOC and the Republics of Kazakhstan and
Uzbekistan concluded negotiations resulting in amendments to their respective
Suspension Agreements. Both amendments are effective for 10 years and provide
that uranium mined in those republics and enriched in another country (known as
"by-pass" arrangements) will no longer be considered to have undergone
substantial transformation, and will therefore count against their import
quotas. However, the initial price range under the Kazakhstan Suspension
Agreement has been reduced to $12.00 -- $12.99 from $13.00 -- $13.99. The
publishing of the DOC semi-annual price of $12.06 allowed up to 500,000 pounds
U(3)O(8) to be imported into the United States from Kazakhstan during the
period between April and September 1995. More recently, the publication of the
DOC semi-annual price of $15.78 on October 1, 1996, allowed Kazakhstan to
export up to 700,000 pounds of U(3)O(8) into the United States between October
1996 and March 31, 1997.  The latest determination resulted in a price of
$11.76 which is below the floor precluding deliveries from Kazakhstan between
April and October 31, 1998.  Uzbekistan would have been entitled to a sales
quota of 940,000 pounds U(3)O(8) in each of the next two years provided the DOC
calculated price would have remained at or above $12.00 per pound. For the
remaining eight years the sales quota is tied to United States production
levels: 600,000 pounds U(3)O(8) when United States production is between 3 and
3.5 million pounds U(3)O(8), rising to 1 million pounds when United States
production is between 8.5 and 9 million pounds and unlimited when United States
production exceeds 9 million pounds.

These amendments to the Suspension Agreements may increase the supply of
uranium to the United States market and provide increased predictability
concerning CIS imports into the United States. Due to declining production





                                       46
<PAGE>   47



levels in the CIS republics, uranium from these sources has recently been
difficult to obtain. Consequently, the Registrant believes that the market
impact of CIS supplies is diminishing.

In Europe, the Euratom Supply Agency, which has approval authority over all
uranium-related contracts entered into in the European Community ("EC"), has an
informal policy limiting CIS sales into the EC to about 20% of annual
individual utility requirements. The United States and EC restrictions have no
effect on the sales of CIS uranium to other countries although, due to
political disputes between Russia and Japan, there has been a general
reluctance by Japanese utilities to purchase Russian sourced uranium.

HIGHLY ENRICHED URANIUM SUPPLY

In January 1994, the United States and Russia entered into an agreement (the
"Russian HEU Agreement") to convert highly enriched uranium ("HEU"), derived
from dismantling nuclear weapons, into low enriched uranium ("LEU") suitable
for use in nuclear power plants.  The first shipment of Russian HEU to the
United States took place in the June 1995 with total deliveries in 1995 of
about 5 million pounds eU(3)O(8).  None of this was sold in the United States
market due to a prohibition contained in the Russian Suspension Agreement.  To
overcome this impediment and concerns of United States producers, the United
States Enrichment Corporation ("USEC") and others in the industry, the United
States government provided a vehicle, via the USEC Privatization Act, for the
sale of Russian uranium acquired pursuant to the Russian HEU Agreement in the
United States commercial uranium market.

In November 1996, USEC and Techsnabexport, the Russian Executive Agent, amended
the original Russian HEU Agreement to provide for prices and quantities over a
5-year period.  As a result, the Russians would blend down (i) 18 metric tons
in 1997, (ii) 24 metric tons in 1998, and (iii) 30 metric tons in 1999 through
2001.

Through December 31, 1996, the quantity of LEU purchased from the Russian
Executive Agent was less than 18 metric tons of blended HEU (14 million pounds
U(3)O(8)), rather than the 30 metric tons that had been specified in the
original HEU Agreement.  The 14 million pounds of uranium purchased by USEC was
subsequently transferred to DOE to be sold by the following means:  (1) at any
time for end use outside the United States, (2) to the Russian Executive Agent
for use in matched sales pursuant to the Russian Suspension Agreement, or (3)
in calendar year 2001 for consumption by end users in the United States not
prior to January 1, 2002 in volumes not to exceed 3 million pounds eU(3)O(8)
per year.

The USEC Privatization Act authorizes the DOE to transfer to USEC up to 7,000
metric tons of surplus natural uranium and LEU, equivalent to about 18 million
pounds U(3)O(8) and 50 metric tons of HEU from United States stockpiles.  In
addition to these transfers, the DOE was also authorized by the USEC
Privatization Act to sell its remaining surplus natural uranium and LEU.  The
Secretary of Energy, however, must determine that the sales of surplus uranium,
which is about 21 million pounds eU(3)O(8), will not have an adverse material
impact on the domestic mining, conversion, and enrichment industries, and that
the price paid for the uranium is not less than fair market value.

URANIUM PRICES

Most of the countries that use nuclear-generated electricity do not have a
sufficient domestic uranium supply to fuel their nuclear power reactors, and
their electric utilities secure a substantial part of their required uranium
supply by entering into medium-term and long-term contracts with foreign
uranium producers. These contracts usually provide for deliveries to begin one
to three years after they are signed and to continue for several years
thereafter. In awarding medium-term and long-term contracts, electric utilities
consider, in addition to the commercial terms offered, the producer's uranium
reserves, record of performance and cost competitiveness, all of which are
important to the producer's ability to fulfill long-term supply commitments.
Under medium-term and long-term contracts, prices are established by a number
of methods, including base prices adjusted by inflation indices, reference
prices (generally spot price indicators but also long-term reference prices)
and annual price negotiations. Many contracts also contain floor prices,
ceiling prices, and other negotiated provisions which affect the amount paid by
the buyer to the seller. Prices under these contracts are usually confidential.


Electric utilities procure their remaining requirements through spot and
near-term purchases from uranium producers and traders. Traders source their
uranium from organizations holding excess inventory, including utilities,
producers and governments. With the bankruptcy of Nuexco, and the closure of
by-pass arrangements resulting from the amendments to the Suspension Agreements
with the respective CIS republics, spot market activity increased to





                                       47
<PAGE>   48



42 million pounds U(3)O(8) in 1997, a volume estimated by the UI to be
equivalent to about 30% of Western World reactor requirements.

Spot prices reflect the price at which uranium may be purchased for delivery
within one year. Historically, spot prices have been more volatile than
long-term contract prices, increasing from $6.00 per pound U(3)O(8) in 1973 to
$43.00 in 1978, then declining from $40.00 in 1980 to a low of $7.25 in October
of 1991. More recently, prices have receded from a 1997 year-end spike of
$12.75 to a relative market low just below $11.00.

Trade restrictions limiting the free flow of uranium from the CIS republics
into the Western World markets, including the negotiation by the DOC of
amendments to the Suspension Agreements with Kazakhstan and Uzbekistan
resulting in the elimination of European enrichment for uranium from these
republics as a vehicle to by-pass United States import restrictions, the Nuexco
bankruptcy under Chapter 11 of the United States Bankruptcy Code and related
defaults on deliveries (see "Bankruptcy of Oren Benton and Nuexco") and the
reluctance of uranium producers and inventory holders to sell at low spot price
levels, contributed to the increase in spot prices between 1995 and 1997.
Since that time, these factors have had a diminishing impact on the uranium
market causing prices to over correct in a downward trend.  Particularly, in
the case of NUEXCO bankruptcy.

Future uranium prices will depend largely on the amount of incremental supply
made available to the spot market from the remaining excess inventories,
primary production in Russia and other CIS republics, as well as supplies from
Russian HEU and its other stockpiles, from excess United States HEU and
increased production from unutilized capacity of other uranium producers.
Analysts believe, however, that prices will continue to stabilize throughout
1998 and begin to push higher over the next couple of years.

COMPETITION

The Registrant markets uranium to utilities in direct competition with supplies
available from various sources worldwide. The Registrant competes primarily on
the basis of price. Although the Registrant expects to be a significant United
States producer of uranium, its total production will be a small percentage of
total Western World production.

The uranium production according to the industry international in scope and is
characterized by a relatively small number of companies operating in only a few
nations. In 1996, six companies, Cameco, Compagnie Generales des Matieres
Nucleaires ("Cogema"), Energy Resources of Australia Ltd. ("ERA"), The RTZ
Corporation PLC ("RTZ"), Uranerzbergbau-GmbH ("Uranerz") and WMC Limited,
produced over 60% of total world output. Most of Western World production was
from only eight nations: Canada, Niger, Australia, Namibia, South Africa,
United States, France, and Gabon. In 1988, the former Soviet Union, now known
as the CIS, and Mainland China began to supply significant quantities of
uranium annually into Western World markets.

The Canadian uranium industry has in recent years been the leading world
supplier, producing 29.5 million pounds U(3)O(8) in 1996, or about 48% of total
Western World production.

                              THE VANADIUM MARKET

As a co-product of the production of uranium from the Colorado Plateau District
ores, the Registrant will produce and sell vanadium. These deposits have been
mined for over 100 years, and significant reserves remain.

Vanadium is an essential alloying element for steels and titanium, and its
chemical compounds are indispensable for many industrial and domestic products
and processes. The principal uses for vanadium are: (i) carbon steels used for
reinforcing bars; (ii) high strength, low alloy steels used in construction and
pipelines; (iii) full alloy steels used in castings; (iv) tool steels used for
high speed tools and wear resistant parts; (v) titanium alloys used for jet
engine parts and air frames; and (vi) various chemicals used as catalysts.

Principal sources of vanadium are (i) titaniferous magnetites found in Russia,
China and South Africa; (ii) sludges and fly ash from the refining and burning
of the U.S., Caribbean and Middle Eastern oils; and (iii) uranium co-product
production from the Colorado Plateau. While produced and sold in a variety of
ways, vanadium production figures and prices are typically reported in pounds
of an intermediate product, vanadium pentoxide, or V(2)O(5). The White Mesa
Mill is capable of producing two products, ammonium metavanadate ("AMV"), an
intermediate product, and vanadium pentoxide ("flake", "black flake", "tech
flake" or "V(2)O(5)"). The majority of sales are as V(2)O(5), with AMV being
produced and sold on a request basis only.





                                       48
<PAGE>   49



Vanadium is generally produced as a by- or co-product of other metal
production. In the United States, the most significant source of production has
been as a by-product of uranium production from ores in the Colorado Plateau
District, accounting for over half of historic U.S. production. Vanadium in
these deposits occurs at an average ratio of seven pounds of vanadium for every
pound of uranium, and the financial benefit derived from the by-product sales
have helped to make the mines in this area profitable. However, low prices for
both uranium and vanadium in recent years have forced all producers in the
Colorado Plateau District to place their facilities on standby.

The market for vanadium has fluctuated greatly over the last 15 years. Over
capacity in the mid 1970's was caused by reduced demand for vanadium during the
recession that plagued the steel industry. By the end of the decade, steel
production had climbed to record levels and prices for V(2)O(5) firmed at
around $2.75 per pound. During the early 1980's, quoted prices were in the
range of $3.00 per pound, but increased exports from China and Australia,
coupled with the continued economic recession of the 1980's drove prices to as
low as $1.30 per pound. Prices stabilized in the $2.00 - $2.45 per pound range
until perceived supply problems in 1988 caused by cancellation of contracts by
China and rumors of South African production problems resulted in a price
run-up of unprecedented magnitude, culminating in an all time high of nearly
$12.00 per pound in February of 1989. This enticed new producers to construct
additional capacity and over-supply problems again depressed the price in the
early 1990's to $2.00 per pound and below. Late in 1994, a reduction in
supplies from Russia and China, coupled with concerns about the political
climate in South Africa and a stronger steel market caused the price to climb
to $4.50 per pound early in 1995.  In the beginning of 1998, prices had climbed
to a nine-year high of $7.00 caused by a supply deficit unable to keep pace
with record demand from steel and aerospace industries.  Increased market
demand and consumption, is expected to remain strong sustaining prices at these
near record highs for the next two years.

Vanadium supply and demand estimates for the near future show yearly
consumption to increase at a rate of 5% from its current level of 130 million
pounds V(2)O(5).  World wide production capacity is expected to increase from
its current level of 120 million pounds beginning in the year 2000,
notwithstanding the Registrant's anticipated start up in 1998.   Recent
comments in trade journals have indicated that the major South African
producers have augmented their production by the integration of their
ferro-vanadium production. The net effect of reduction in the flow of V(2)O(5)
from South Africa to converters in Europe and Japan, and lagging increases in
production have caused consumers to scramble for feedstocks. This, coupled with
projected worldwide yearly steel consumption of over 100 million tons in 1997
and 1998, and the apparent inability of Russia and China to produce enough
vanadium for even their internal needs, point to sustained prices in the range
of $5.00 - $6.00 per pound.

Historically, vanadium has been largely producer priced, but during the 1980's,
this came under pressure due to the emergence of new sources. As a result,
merchant or trader activity gained more and more importance. While a very large
portion of the supply continues to come from a few major producers in South
Africa, the prices for the products that will be produced by the Registrant
will be based on weekly quotations of the LME. Historically, vanadium
production from the White Mesa Mill has been sold into the world-wide market
both through traders, who take a 2% to 3% commission for their efforts and, to
a lesser extent, through direct contacts with domestic converters and
consumers. While priced in U.S. dollars per pound of V(2)O(5), the product is
typically sold by the container, which contains nominally 40,000 pounds of
product packed in 55 gallon drums, each containing 550 pounds of product.
Typical contracts will call for the delivery of one to two containers per month
over a year or two to a customer with several contracts in place at the same
time. Pricing is usually based on the LME price and may include floor and
ceiling price protection for both the producer and seller. Spot sales are also
made based on the current LME quote.

       year following the date of listing of the Registrant's common shares on
       The Toronto Stock Exchange, i.e. on May 16, 1998.  The balance of the
       shares will be released as to one-fifth on each of the following
       anniversary dates so that all of the shares will be released by May 16,
       2002.

ITEM 5 - NATURE OF THE TRADING MARKET

The Ontario Business Corporations Act, the Securities Act of the Province of
Ontario and the rules and policies of the Toronto Stock Exchange govern
issuance and trading of the Registrant's common stock.

As at March 31, 1998, approximately 6,031,200 of the Registrant's outstanding
common stock were registered in the names of residents of the United States.
The Registrant's common stock is issued in registered form and the percentage
of shares reported to be held by U.S. shareholders of record is taken from the
records of The Montreal Trust Company of Canada, the registrar and transfer
agent for the Common Stock.

The common shares of the Registrant are currently listed on The Toronto Stock
Exchange in Canada.  The Registrant's common shares commenced trading on The
Toronto Stock Exchange on May 16, 1997.  The following table sets forth the
high and low market prices and the volume of the common shares traded on The
Toronto Stock Exchange during the periods indicated:

ITEM 6 - EXCHANGE CONTROLS AND OTHER LIMITATIONS AFFECTING SECURITY HOLDERS

Canada has no system of exchange controls.  There are no foreign exchange
restrictions on the export or import of capital or on the remittance of
dividends, interest, or other payments to non-resident holders of the Company's
securities.

Under the Investment Canada Act, the acquisition of "control" of certain
"businesses" by "non-Canadians" is subject to either notification or review
requirements by Investment Canada , a governmental agency, and will not be
allowed unless they are found likely to be of net benefit to Canada.  The term
"control" is defined as any one or more non-Canadian persons acquiring all or
substantially all of the assets used in the Canadian business, or acquisition
of the voting shares of a Canadian corporation carrying on the Canadian
business or the acquisition of the voting interests of an entity controlling
the Canadian corporation.  The acquisition of the majority of the outstanding
shares or the acquisition of less than a majority but 1/3 or more of the voting
shares unless it can be shown in fact that the purchaser will not control the
Canadian company shall be deemed to be "control".

An acquisition will be reviewable by Investment Canada only if the value of the
assets of the Canadian business being acquired is Cdn$5 million or more in the
case of a "direct" acquisition (or where the Canadian asset acquired constitute
more that 50% of the value of all entities acquired), or Cdn$50 million or more
in the case of an "indirect" acquisition.

These thresholds have been increased for the purpose of acquisition of Canadian
businesses by investors from members of the World Trade Organization ("WTO"),
including Americans, or WTO member-controlled companies.  A direct acquisition
by a WTO investor is reviewable only if it involves the direct acquisition of a
Canadian business with assets of Cdn$179 million or more (this figure is
adjusted annually to reflect inflation).  Indirect acquisitions by WTO
investors are not reviewable, regardless of the size of the Canadian business
acquired, unless the Canadian, assets acquired constitute more than 50% of the
value of all entities acquired, in which case the Cdn$179 million threshold
applies.

These increased thresholds do not apply to acquisitions of Canadian businesses
engaged in certain sensitive areas such as uranium production, financial
services, transportation or cultural heritage or national identity.  If the
forgoing thresholds are not met, the acquisition of a Canadian business will
not be subject to review unless it relates to Canada's cultural heritage or
national identity.

If an investment is reviewable, an application for review in the form
prescribed by regulation is normally required to be filed with the Agency
(established by the Act) prior to the investment taking place and the
investment may not be consummated until the review has been completed.  There
are, however, certain exceptions.  Applications concerning indirect
acquisitions may be filed up to 30 days after the investment is consummated;
applications concerning reviewable investments in culture-sensitive sectors are
required upon receipt of a notice for review.

There is, moreover, provision for the Minister (a person designated as such
under the Act) to permit an investment to be consummated prior to completion of
review if he is satisfied that delay would cause undue hardship to the acquirer
or jeopardize the operation of the Canadian business that is being acquired.
The Agency will submit the application to the Minister, together with any other
information or written undertakings given by the acquirer and any
representation submitted to the Agency by a province that is likely to be
significantly affected by the investment.

The Minister will then determine whether the investment is likely to be of net
benefit to Canada, taking into account the information provided and having
regard to factors of assessment where they are relevant.  Some of the factors
to be considered are the effect of the investment on the level and nature of
economic activity in Canada, including the effect on employment, on resource
processing on the utilization of parts, components and services produced in
Canada, and on exports from Canada.  Additional factors of assessment include
(i) the degree and significance of participation by Canadians in the Canadian
business and in any industry in Canada of which it forms a part; (ii) the
effect of the investment on productivity, industrial efficiency, technological
development, product innovation and product variety in Canada; (iii) the effect
of the investment on competition within any industry or industries in Canada;
(iv) the compatibility of the investment with national industrial, economic and
cultural policies taking into consideration industrial, economic and cultural
policy objectives enunciated by the government or legislature of any province
likely to be significantly affected by the investment; and (v) the contribution
of the investment to Canada's ability to compete in world markets.





                                       51
<PAGE>   52



If an acquisition of control of a Canadian business by a non-Canadian is not
reviewable, the non-Canadian must still give notice to Investment Canada of the
acquisition of a Canadian business within 30 days after its completion.

There are no limitations under Canadian law on the right of nonresident or
foreign owners to hold or vote the common stock of the Registrant.

ITEM 7 - TAXATION

The following paragraphs set forth certain United States and Canadian income
tax considerations about the ownership of common shares of the Registrant.
These tax considerations are stated in general terms. There may be relevant
state, provincial or local income tax considerations, which are not discussed.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

The following is a general discussion of certain possible United states federal
income tax consequences, under current law, generally applicable to a U.S.
Holder (as defined below) of common shares of the Registrant.  This discussion
does not address all potentially relevant federal income tax matters and it
does not address consequences peculiar to persons subject to special provisions
of federal income tax law, such as those described below as excluded from the
definition of a U.S. Holder.  In addition, this discussion does not cover any
state, local or foreign tax consequences. (See "Taxation - Certain Canadian
Federal Tax Considerations" below.)

The following discussion is based upon the sections of the Internal Revenue
Code of 1986, as amended (the "Code"), Internal Revenue Service ("IRS")
rulings, published administrative positions of the IRS and court decisions that
are currently applicable, any or all of which could be materially and adversely
changed, possibly on a retroactive basis, at any time.  This discussion does
not consider the potential effects, both adverse and beneficial, of any
recently proposed legislation which, if enacted, could be applied, possibly on
a retroactive basis, at any time. This discussion is for general information
only and it is not intended to be, nor should it be construed to be legal or
tax advice to any holder or prospective holder of common shares of the
Registrant and no opinion or representation with respect to the United States
federal income tax consequences to any such holder or prospective holder is
made.  Accordingly, holders and prospective holders of common shares of the
Registrant should consult their own tax advisors about the federal, state,
local, and foreign tax consequences of purchasing, owning and disposing of
common shares of the Registrant.

U.S. HOLDERS

As used herein, a "U.S. Holder means a holder of common shares of the
Registrant who is a citizen or individual resident of the United States, a
corporation or partnership created or organized in or under the laws of the
United States or of any political subdivision thereof or a trust whose income
is taxable in the United States irrespective of source.  This summary does not
address the tax consequences to, and U.S. Holder does not include persons
subject to specific provisions of federal income tax law, such as tax-exempt
organizations, qualified retirement plans, individual retirement accounts and
other tax-deferred accounts, financial institutions, insurance companies, real
estate investment trusts, regulated investment companies, broker-dealers, non-
resident alien individuals, persons or entities that have a "functional
currency" other than the U.S. dollar, shareholders who hold common shares as
part of a straddle, hedging or a conversion transaction, and shareholders who
acquired their stock through the exercise of employee stock options or
otherwise as compensation for services. This summary is limited to U.S. Holders
who own common shares as capital assets. This summary does not address the
consequences to a person or entity holding an interest in a shareholder or the
consequences to a person of the ownership exercise or disposition of any
options, warrants or other rights to acquire common shares.

DISTRIBUTIONS ON COMMON SHARES OF THE REGISTRANT

U.S. Holders receiving dividend distributions (including constructive
dividends) with respect to common shares of the Registrant are required to
include in gross income for United States federal income tax purposes the gross
amount of such distributions equal to the U.S. dollar value of such dividends
on the date of receipt (based on the exchange rate on such date) to the extent
that the Registrant has current or accumulated earnings and profits, without
reduction for any Canadian income tax withheld from such distributions. Such
Canadian tax withheld may be credited, subject to certain limitations, against
the U.S. Holder's United States federal income tax liability or, alternatively,
may be deducted in computing the U.S. Holder's United States federal taxable
income by those who itemize deductions. (See discussion that is more detailed
at "Foreign Tax Credit" below.) To the extent that





                                       52
<PAGE>   53



distributions exceed current or accumulated earnings and profits of the
Registrant, they will be treated first as a return of capital up to the US.
Holders' adjusted basis in the common shares and thereafter as gain from the
sale or exchange of the common shares.  Preferential tax rates for long-term
capital gains are applicable to a U.S. Holder which is an individual, estate or
trust. There are currently no preferential tax rates for long- term capital
gains for a U S. Holder, which is a corporation.

In the case of foreign currency received as a dividend that is not converted by
the recipient into U.S. dollars on the date of receipt, a U.S. Holder will have
a tax basis in the foreign currency equal to its U.S. dollar value on the date
of receipt.  Any gain or loss recognized upon a subsequent sale or other
disposition of the foreign currency, including an exchange for U.S. dollars,
will be ordinary income or loss.

Dividends paid on the common shares of the Registrant will not generally be
eligible for the dividends received deduction provided to corporations
receiving dividends from certain United States corporations. A U.S. Holder
which is a corporation may, under certain circumstances, be entitled to a 70%
deduction of the United States source portion of dividends received from the
Registrant (unless the Registrant qualifies as a "foreign personal holding
Registrant" or a "passive foreign investment company," as defined below) if
such U.S. Holder owns shares representing at least 10% of the voting power and
value of the Registrant.  The availability of this deduction is subject to
several complex limitations, which are beyond the scope of this discussion.

FOREIGN TAX CREDIT

A U.S. Holder who pays (or has withheld from distributions) Canadian income tax
with respect to the ownership of common shares of the Registrant may be
entitled, at the option of the U.S. Holder, to either a deduction or a tax
credit for such foreign tax paid or withheld. Generally, it will be more
advantageous to claim a credit because a credit reduces United States federal
income taxes on a dollar-for-dollar basis, while a deduction merely reduces the
taxpayer's income subject to tax. This election is made on a year-by-year basis
and applies to all foreign taxes paid by (or withheld from) the U.S. Holder
during that year. There are significant and complex limitations which apply to
the credit, among which is the general limitation that the credit cannot exceed
the proportionate share of the U.S. Holder's United States income tax liability
that the U.S. Holder's foreign source income bears to his or its worldwide
taxable income. In the determination of the application of this limitation, the
various items of income and deduction must be classified into foreign and
domestic sources. Complex rules govern this classification process. In
addition, this limitation is calculated separately with respect to specific
classes of income such as "passive income", "high withholding tax interest",
"financial services income", "shipping income", and certain other
classifications of income.  Dividends distributed by the Registrant will
generally constitute "passive income" or, in the case of certain U.S. Holders,
"financial services income" for these purposes. The availability of the foreign
tax credit and the application of the limitations on the credit are fact
specific, and holders and prospective holders of common shares of the
Registrant should consult their own tax advisors regarding their individual
circumstances.

DISPOSITION OF COMMON SHARES OF THE REGISTRANT

A U.S. Holder will recognize gain or loss upon the sale of common shares of the
Registrant equal to the difference, if any, between (i) the amount of cash plus
the fair market value of any property received, and (ii) the shareholder's tax
basis in the common shares of the Registrant. This gain or loss will be capital
gain or loss if the common shares are a capital asset in the hands of the U.S.
Holder, which will be a short-term or long-term capital gain or loss depending
upon the holding period of the U.S. Holder.  Gains and losses are netted and
combined according to special rules in arriving at the overall capital gain or
loss for a particular tax year.  Deductions for net capital losses are subject
to significant limitations.  For U.S. Holders who are individuals, any unused
portion of such net capital loss may be carried over to be used in later tax
years until such net capital loss is thereby exhausted.  For U.S. Holders that
are corporations (other than corporations subject to Subchapter S of the Code),
an unused net capital loss may be carried back three years from the loss year
and carried forward five years from the loss year to be offset against capital
gains until such net capital loss is thereby exhausted.

OTHER CONSIDERATIONS

In the following circumstances, the above sections of this discussion may not
describe the United States federal income tax consequences resulting from the
holding and disposition of common shares:





                                       53
<PAGE>   54



FOREIGN PERSONAL HOLDING REGISTRANT

If at any time during a taxable year more than 50% of the total combined voting
power or the total value of the Registrant's outstanding shares is owned,
directly or indirectly, by five or fewer individuals who are citizens or
residents of the United States and 60% or more of the Registrant's gross income
for such year was derived from certain passive sources (e.g., from dividends
received from its subsidiaries), the Registrant may be treated as a "foreign
personal holding Registrant".  In that event, U.S. Holders that hold common
shares would be required to include in gross income for such year their
allocable portions of such passive income to the extent the Registrant does not
actually distribute such income.

FOREIGN INVESTMENT REGISTRANT

If 50% or more of the combined voting power or total value of the Registrant's
outstanding shares are held, directly or indirectly, by citizens or residents
of the United States, United States domestic partnerships or corporations, or
estates or trusts other than foreign estates or trusts (as defined by the Code
Section 7701 (a)(31)), and the Registrant is found to be engaged primarily in
the business of investing, reinvesting, or trading in securities, commodities,
or any interest therein, it is possible that the Registrant may be treated as a
"foreign investment company" as defined in Section 1246 of the Code, causing
all or part of any gain realized by a U.S. Holder selling or exchanging common
shares to be treated as ordinary income rather than capital gain.  

PASSIVE FOREIGN INVESTMENT REGISTRANT

As a foreign corporation with U.S. Holders, the Registrant could potentially be
treated as a passive foreign investment company ("PFIC"), as defined in section
1296 of the Code, depending upon the percentage of the Registrant's income
which is passive, or the percentage of the Registrant's assets which is
producing passive income.  U.S. Holders owning common shares of a PFIC are
subject to an additional tax and to an interest charge based on the value of
deferral of tax for the period during which the common shares of the PFIC are
owned, in addition to treatment of gain realized on the disposition of common
shares of the PFIC as ordinary income rather than capital gain.  However, if
the U.S. Holder makes a timely election to treat a PFIC as a qualified electing
fund ("QEF") with respect to such shareholders interest therein, the above-
described rules generally will not apply.  Instead, the electing U.S. Holder
would include annually in his gross income his pro rata share of the PFIC's
ordinary earnings and net capital gain regardless of whether such income or
gain was actually distributed.  A U.S. Holder of a QEF can, however, elect to
defer the payment of United States federal income tax on such income
inclusions.  Special rules apply to U.S. Holders who own their interests in a
PFIC through intermediate entities or persons.

The Registrant believes that it was not a PFIC for its fiscal year ended
September 30, 1997, and quarters ended December 31, 1997 and March 31, 1998.
If in a subsequent year the Registrant concludes that it is a PFIC, it intends
to make information available to enable an U.S. Holder to make a QEF election
in that year. There can be no assurance that the Registrant's determination
concerning its PFIC status will not be challenged by the IRS, or that it will
be able to satisfy record keeping requirements which will be imposed on QEF's.

CONTROLLED FOREIGN CORPORATION

If more than 50% of the voting power of all classes of stock or the total value
of the stock of the Registrant is owned, directly or indirectly, by citizens or
residents of the United States, United States domestic partnerships and
corporations or estates or trusts other than foreign estates or trusts, each of
whom own 10% or more of the total combined voting power of all classes of stock
of the Registrant ("United States shareholder"), the Registrant could be
treated as a "controlled foreign corporation" under Subpart F of the Code.
This classification would effect many complex results including the required
inclusion by such United States shareholders in income of their pro rata shares
of "Subpart F income" (as specially defined by the Code) of the Registrant. In
addition, under Section 1248 of the Code, gain from the sale or exchange of
stock by a holder of common shares of the Registrant who is or was a United
States shareholder at any time during the five year period ending with the sale
or exchange is treated as ordinary dividend income to the extent of earnings
and profits of the Registrant attributable to the stock sold or exchanged.
Because of the complexity of subpart F and because it is not clear that Subpart
F would apply to the holders of common shares of the Registrant, a more
detailed review of these rules is outside of the scope of this discussion.

<PAGE>   55



CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

The summary below is restricted to the case of a holder (a "Holder") of one or
more common shares who for the purposes of the Income Tax Act (Canada) (the
"Act") is a non-resident of Canada, holds his common shares as capital property
and deals at arm's length with the Registrant.

DIVIDENDS

A Holder will be subject to Canadian withholding tax ("Part XIII Tax") equal to
25%, or such lower rate as may be available under an applicable tax treaty, of
the gross amount of any dividend paid or deemed to be paid on his common
shares.  Under the 1995 Protocol amending the Canada-U.S. Income Tax Convention
(1980) (the "Treaty") the rate of Part XIII Tax applicable to a dividend on
common shares paid to a Holder who is a resident of the United States is, if
the Holder is a company that beneficially owns at least 10% of the voting stock
of the Registrant, 6% (1996) and 5% (after 1996) in any other case, 15% of the
gross amount of the dividend.  The Registrant will be required to withhold the
applicable amount of Part XIII Tax from each dividend so paid and remit the
withheld amount directly to the Receiver General for Canada for the account of
the Holder.

DISPOSITION OF COMMON SHARES

A Holder who disposes of a common share, including by deemed disposition on
death, will not be subject to Canadian tax on any capital gain (or capital
loss) thereby realized unless the common share constituted "taxable Canadian
property" as defined by the Act.  Generally, a common share will not constitute
taxable Canadian property of a Holder unless he held the common share as
capital property used by him carrying on a business (other than an insurance
business) in Canada, or he or persons with whom he did not deal at arm's length
alone or together held or held options to acquire, at any time within the five
years preceding the disposition, 25% or more of the shares of any class of the
capital stock of the Registrant.

A Holder who is a resident of the United States and realizes a capital gain on
disposition of a common share that was taxable Canadian property will
nevertheless, by virtue of the Treaty, generally be exempt from Canadian tax
thereon unless (a) more than 50% of the value of the common share is derived
from, or for an interest in, Canadian real estate, including Canadian mineral
resource properties, (b) the common share formed part of the business property
of a permanent establishment that the Holder has or had in Canada within the 12
months preceding disposition, or (c) the Holder (i) was a resident of Canada at
any time within the ten years immediately, and for a total of 120 months during
the 20 years, preceding the disposition, and (ii) owned the common share when
he ceased to be resident in Canada.

A Holder who is subject to Canadian tax in respect of a capital gain realized
on disposition of a common share must include three quarters of the capital
gain (taxable capital gain) in computing his taxable income earned in Canada.
The Holder may, subject to certain limitations, deduct three quarters of any
capital loss (allowable capital loss) arising on disposition of taxable
Canadian property from taxable capital gains realized in the year of
disposition in respect to taxable Canadian property and, to the extent not so
deductible, from such taxable capital gains of any of the three preceding years
or any subsequent year.

ITEM 9 -  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITIONS
          AND RESULTS OF OPERATIONS

The following discussion of the financial condition and results of operations of
the Registrant for the fiscal year September 30, 1997, and the six month period
ending, March 31, 1998, should be read in conjunction with the consolidated
financial statements of the Registrant and related notes therein. The
Registrant's consolidated financial statements are prepared in accordance with
Canadian generally accepted accounting principles. Historical Financial
Statements for Energy Fuels have not been included in this Registration
Statement. See Item 17 for a further discussion of this matter.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS FOR THE PERIOD ENDED SEPTEMBER 30, 1997.

RESULTS OF OPERATIONS

For the period from inception through May 9, 1997, the Registrant's activities
were focused on the acquisition and financing of the Energy Fuels assets;
therefore, costs and expenses relating to these activities were either
capitalized and included in the costs of the assets acquired or applied against
the financing proceeds received, as appropriate, in accordance with generally
accepted accounting principles in Canada.

For the period from May 10, 1997 through September 30, 1997 (year-end), the
Registrant received $523,000 of processing fees from alternate feed contracts
and received interest income of $782,000 on available cash balances and
interest related to collections of notes receivable.  Total expenses were
$1,287,000, of which $238,000 was attributed to direct costs of operations and
$1,008,000 to selling, general and administrative costs.  Depreciation and
amortization for the period totalled $41,000 resulting in net income from
operations for the period of $18,000.

Direct operating costs relating to uranium produced from the Registrant's
alternate feed contracts were included in inventory costs.  Uranium production
totalled 185,840 pounds as of September 30, 1997, which were produced for a
cost of $1,275,000 ($6.86 per pound).

Costs relating to the restoration and start-up development of the Sunday Mine
totaling $463,000 were also capitalized and included in mining properties at
year-end.  These costs will be depleted as ore is produced from the property.

FINANCIAL POSITION

The two most significant events which affected the Registrant's financial
position were the completion of a special warrant financing and the acquisition
of the Energy Fuels assets.

The Registrant has placed $7,945,000 on deposit in short-term marketable
investments in favor of its bonding company to secure certain reclamation
bonds.  Investment income will be released from these investments, and
additional deposits will be reserved, in accordance with the Registrant's
bonding requirements, as its estimated reclamation obligations are revised over
time.

The Registrant increased its capital investment in machinery and equipment by
approximately $1,949,000 in order to improve its milling, mining and
exploration activities.  Additionally, approximately $729,000 was expended on
mine development and property costs during the period.  This was in addition to
the approximate $1,192,000 increase in exploration cost for the period from May
through September relating to the Mongolian Joint Venture.  In total,
approximately $3,870,000 of funds were expended for mining properties, plant,
equipment and exploration.  Plant and equipment costs will be depreciated over
their estimated useful lives, while mine development and exploration costs will
be amortized using the units-of-production method.  If an exploration project
is unsuccessful, all remaining capitalized expenditures will be written off.

CAPITAL RESOURCES AND LIQUIDITY

The Registrant's working capital at September 30, 1997 was $24,283,000 of which
$13,953,000 consisted of cash.  The Registrant expects its revenues from
uranium and vanadium sales, and from alternate feed processing to provide net
income and additional working capital in the coming fiscal year.

The Registrant is also budgeting capital improvements for the Mill and other
operations of approximately $1,625,000 in fiscal year 1998.  Exploration, mine
development and property holding expenditures are anticipated to be
approximately $6,700,000, of which approximately $3,950,000 will be expended
for exploration in Mongolia.

The Registrant is anticipating funding these outlays from current operations
and working capital (which is sufficient to cover these planned expenditures).
Nonetheless, the Company is considering the possibility of negotiating and
having available a short-term revolving credit facility during the coming
fiscal year to assist and supplement inventory and project financing, in
addition to providing short-term cash flexibility if necessary.

1998 FISCAL YEAR OUTLOOK

The following are forward looking statements - see "Special Note Regarding
Forward Looking Statements."

The Registrant anticipates achieving full production at its Sunday Mine Complex
during the year along with the commencement of production at its Rim Mine.
This ore will be stockpiled at the Mill and is expected to be supplemented with
ore purchased from other independent mines in the Colorado Plateau District.

It is anticipated that the Mill will commence processing these conventional
ores in the fourth quarter of the calendar year 1998.  In addition to uranium,
these ores contain significant grades of vanadium, which will also be processed
at the Mill and sold to customers.  Prior to the conventional ore run, the
Registrant will continue and, if possible, expand upon its current alternate
feed processing program.  Based on the Registrant achieving its forecasted
mining and milling activities, production from conventional and alternate feeds
should exceed 250,000 pounds of uranium concentrates and 1,200,000 pounds of
vanadium concentrates for the calendar year ending 1998.  To supplement its own
production, the Registrant is under contract to purchase uranium concentrates
during the next year at prices approximating the market value at the time of
delivery.

The Registrant anticipates that it will continue to be active in the spot and
long-term uranium sales market, based on production and inventory levels as
discussed above and additionally due to the Registrant's forecasted production
costs being below current market prices.  The Registrant will also be an active
participant in the vanadium market as such material is produced from the
Colorado Plateau District ores.

The Registrant, while producing from its Sunday and Rim Mines, will be
expanding its exploration and development work in the United States and
Mongolia, and evaluating the feasibility of bringing additional mining
properties into production.





                                       57
<PAGE>   58



RISKS AND UNCERTAINTIES

Risk factors that affect the Registrant's results include volatility and
sensitivity to market prices for uranium and vanadium, competition,
environmental regulations, the impact of changes in foreign currencies'
exchange rates, political risk arising from operating in Mongolia, changes in
government regulation and policies including trade laws and policies, demand
for nuclear power, dependence on a limited number of customers, replacement of
reserves and production, receipt of permits and approvals from governmental
authorities and other operating and development risks.

As a result of the foregoing and other factors, no assurance can be given as to
the future results, levels of activity and achievement.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS FOR THE SIX MONTHS ENDED MARCH 31, 1998

The Registrant's net income for the first six months of fiscal 1998 was
$1,555,003, or approximately $0.02 per share.  Details on the Registrant's
financial performance are discussed below.

During the period, the Registrant continued mining uranium and vanadium bearing
ores from its mines in the Colorado Plateau District of western Colorado and
eastern Utah.  Stable uranium prices coupled with a strong vanadium market have
encouraged increased mining operations in this district.  In that respect, the
Registrant continues to be pleased with mining operations at its Sunday Mine
Complex.  Additionally, the Registrant commenced mining operations at its Rim
Mine this past February and continued through the quarter.  Production from the
Registrant's mines increased from 1659 tons in the first quarter to over 11,000
tons in the second quarter, with unit production costs below budget.  The
Registrant anticipates that these two mines will ultimately reach a combined
production rate of approximately 8000 tons per month sometime this summer.
This equates to approximately 35,000 pounds of uranium and 265,000 pounds of
vanadium mined per month.  To supplement its own production, the Registrant
continued its ore purchase program, buying ore from other independent miners in
the district.  Ore from the Registrant's mines and purchased ore is being
delivered and stockpiled at the Registrant's White Mesa Mill where it will be
processed upon completion of the current Alternate Feed run.  In light of the
prospects for an improving uranium market combined with a strong vanadium
market, the Registrant continues to evaluate initiating mining operations at
other Registrant mines currently on standby.

The White Mesa Mill remained fully staffed as the Registrant continued
processing alternate feed containing uranium, tantalum, and niobium.  This run
of alternate feed required modifying the process circuit at the Mill. While the
modifications were not overly complex, due to unforeseen variability in the
characteristics of the ore, the process for recovering the tantalum and niobium
is requiring more design and engineering work than was originally contemplated.
As such, operations at the Mill were suspended in late April while the
Registrant and its partners in this deal continue with development work.  These
changes will also require modifications in the commercial terms between the
parties in this transaction.  At the present time, the Registrant believes that
the development work and commercial negotiations will be successful and
anticipates resuming operations during the latter half of June.  This extended
alternate feed run will result in delaying the processing of the Registrant's
conventional ore until late this year.

The Registrant also continued negotiating with several other companies and
government agencies for the processing of additional uranium bearing alternate
feeds.  Despite the delay in the tantalum processing run, the Registrant
remains convinced that production of uranium from materials that are
essentially a waste product will continue to be a growing and profitable
business for the future.

The Gurvan Saihan Joint Venture, the Registrant's Mongolian exploration
enterprise, completed the planning and preparation for the 1998 drilling and
leach test program.  Actual drilling operations began in April and will
continue through the fall of this year.  The Joint Venture will also complete a
field test to establish leach amenability parameters in anticipation of a full-
scale pilot production operation, which is scheduled for the 1999 season.

During the quarter, the Registrant also submitted its license application to
the U.S. Nuclear Regulatory Commission for a Source Materials License for its
Reno Creek in-situ project, located in the Powder River Basin of Wyoming.  The
Registrant is anticipating completion of the license review process by the end
of this year or early 1999.  Based on this schedule, the Registrant could be in
production at Reno Creek by 2000 at a rate of 750,000 pounds per year,
depending upon market conditions at that time.





                                       58
<PAGE>   59



The uranium market was extremely quiet during the past six months.  As
anticipated, spot uranium prices remained soft, dipping during the second
quarter from $12.00 to $10.75 per pound on very little demand.  Analysts are
expecting this situation to continue until at least the fall of this year.
Taking advantage of this market lull, the Registrant did purchase some uranium
during the second quarter at prices under $11.00 per pound in anticipation of
deliveries scheduled for later this year under contracts at significantly
higher prices.  The Registrant had no scheduled sales deliveries of uranium
during the quarter.   Sales deliveries are expected to resume next quarter
based on contracts currently in place.

FINANCIAL REVIEW

As noted, there were no deliveries of uranium during the quarter and
consequently there were no sales revenues.  Due to the delay in the tantalum
alternate feed run, gross revenues from alternate feed processing were less
than anticipated, totaling $4,976,240, while corresponding processing costs
were higher at $3,917,192, resulting in gross operating profits for the quarter
of $1,059,048.  Net interest and other income were $354,311, while office and
administrative expenses were $989,301.  This resulted in net income before
taxes of $424,058, which was less than anticipated.  The provision for income
taxes was $101,714, resulting in net income after taxes for the second fiscal
quarter of $322,344.  For the first six months period ending March 31, 1998,
the Registrant had net income of $1,555,003.  This was derived from total
U(3)O(8) sales revenue of $14,542,800 and process milling fees of $8,613,961
resulting in year to date total revenue of $23,156,761.  U(3)O(8) costs of
sales were $13,663,566 while process milling expenditures were $6,421,768
including depreciation of $111,814.  This resulted in year to date gross
profits from U(3)O(8) sales of $879,234 and from process milling of $2,192,193
for a total gross profit of $3,071,427.

Selling, general and administrative expenses were $1,712,358 for the six-month
period (including depreciation and amortization of $71,204).  Net interest and
other income total $686,990.  Therefore, net income for the period before the
provision for income taxes was $2,046,059.  The year to date income tax
provision totaled $491,056, therefore resulting in net income for the six
months ending March 31, 1998 of $1,555,003.

Year-to-date, the Registrant has invested $2,040,100 in its properties, plant
and equipment, and $1,157,311 in its exploration properties in Mongolia.  As of
March 31, 1998, the Registrant had net working capital of $23,407,669, of which
$13,212,684 was made up of cash and cash equivalents.

NORMAL COURSE ISSUER BID

On June 11, 1998, the Registrant announced that the Toronto Stock Exchange
accepted the Registrant's notice of intention to make a normal course issuer bid
for its common shares through the facilities of the Toronto Stock Exchange. On
and after June 15, 1998, the Registrant may commence making purchases of up to
10% of the public float of its issued and outstanding common shares
(representing approximately 4,118,214 million shares out of 65,743,066 shares
outstanding as at June 9, 1998) on the open market through the facilities of the
Toronto Stock Exchange. Any shares acquired will be purchased at the market
price for the shares at the time of acquisition and will be canceled. The bid
will terminate on the earlier of the Registrant providing notice of termination
or June 14, 1999. Proceeding with the normal course issuer bid will give the
Registrant the flexibility to purchase its shares if it determines that, as a
result of the difference between the Registrant's view of the fundamental value
of the shares and the market price, it is in the best interest of the Registrant
to do so.

ITEM 12 - OPTIONS TO PURCHASE SECURITIES FROM THE REGISTRANT

STOCK OPTION PLAN

The shareholders of the Registrant adopted an employee stock option plan (the
"Stock Option Plan"), under which the board of directors, or a committee
appointed for such purposes, may from time to time grant to directors,
officers, eligible employees of, or consultants to, the Registrant or its
subsidiaries, or to employees of management companies providing services to the
Registrant (collectively, the "Eligible Personnel") options to acquire Common
Shares in such numbers, for such terms and at such exercise prices as may be
determined by the board or such committee. The purpose of the Stock Option Plan
is to advance the interests of the Registrant by providing Eligible Personnel
with a financial incentive for the continued improvement of the Registrant's
performance and encouragement to stay with the Registrant.

The maximum number of Common Shares that may be reserved for issuance for all
purposes under the Stock Option Plan is 6,700,000 Common Shares and the maximum
number of Common Shares which may be reserved for issuance to any one insider
pursuant to share options and under any other share compensation arrangement
may not exceed 5% of the Common Shares outstanding at the time of grant (on a
non-diluted basis). Any Common Shares subject to a share option which for any
reason is cancelled or terminated without having been exercised will again be
available for grant under the Stock Option Plan.

The maximum number of Common Shares that may be reserved for issuance to
insiders of the Registrant under the Stock Option Plan and under any other
share compensation arrangement is limited to 10% of the Common Shares
outstanding at the time of grant (on a non-diluted basis).

The board of directors of the Registrant has the authority under the Stock
Option Plan to establish the option price at the time each share option is
granted. The option price may not be lower than the market price of the Common
Shares at the time of grant.

Options granted under the Stock Option Plan must be exercised no later than 10
years after the date of grant and options are not transferable other than by
will or the laws of dissent and distribution. If an optionee ceases to be an
Eligible Person for any reason whatsoever other than death, each option held by
such optionee will cease to be exercisable 30 days following the termination
date (being the date on which such optionee ceases to be an Eligible Person).
If an optionee dies, the legal representative of the optionee may exercise the
optionee's options within one year after the date of the optionee's death but
only up to and including the original option expiry date.





                                       62
<PAGE>   63



All options granted under the Plan to-date, are exercisable at a price of
Cdn$1.25 and will expire three years from the date of grant. Options granted to
executive officers of the Registrant and its subsidiaries and to certain high
level employees vest as to one-third on the date of grant, as to another
one-third one year after the date of grant and as to the remainder two years
after the date of grant. All other options vest as to one-half on the date of
grant and as to the remainder one year after the date of grant.

The following table sets out information with respect to the options to
purchase common shares of the Registrant outstanding as at September 30, 1997:

Toronto Stock Exchange on September 30, 1997 of Cdn$1.31.

There were no Options/SAR's exercised during the most recently completed
financial year nor were there any Options or SAR's re-priced during the year.

SPECIAL WARRANT FINANCING

Pursuant to an agency agreement dated as of March 14, 1997 (the "Agency
Agreement") entered into between the Registrant and Salman Partners Inc., CIBC
Wood Gundy Securities Inc., Griffiths McBurney & Partners, Newcrest Capital
Inc. and First Marathon Securities Limited (collectively, the "Agents"), the
Agents sold an aggregate of 37,800,00 Special Warrants on behalf of the
Registrant at a price of Cdn.$1.25 per Special Warrant for net proceeds of
$31,784,288.  The transaction closed on March 26, 1997. Each Special Warrant
entitled the holder thereof to acquire one common share of the Registrant
without further payment.  All of the Special Warrants were exercised
immediately prior to the completion of the Amalgamation.

The Registrant used approximately $21,300,000 of the net proceeds from the
Special Warrant placement to complete the acquisition of the Energy Fuels
Assets.  The remainder of the proceeds, approximately $10,490,000 were added to
working capital and will be used by the Registrant to carry out mine
development, Mill refurbishment, mining and additional exploration activities
on its properties and for general corporate purposes.

ITEM 13 - INTEREST OF MANAGEMENT IN CERTAIN TRANSACTIONS

Certain of the directors and officers of the Registrant are also directors and
officers of other natural resource companies and, consequently, there exists
the possibility for such directors and officers to be in a position of
conflict.  Any decision made by any of such directors and officers involving
the Registrant are made in accordance with their duties and obligations to deal
fairly and in good faith with the Registrant and such other companies.  In
addition, each of the directors of the Registrant, discloses and refrains from
voting on, any matter in which such director may have a conflict of interest.

None of the present directors, senior officers or principal shareholders of the
Registrant and no associate or affiliate of any of them has any material
interest in any transaction of the Registrant or in any proposed transaction
which has materially affected or will materially affect the Registrant except
as described herein.

During the period ended September 30, 1997 the Registrant incurred legal fees
of $188,692 with a law firm of which a partner is a director of the Registrant.





                                       64
<PAGE>   65




For all periods through September 30, 1997, the Registrant paid management and
administrative service fees of $343,641 to a company owned by the Chairman of
the Registrant which provides office premises, secretarial and other services
in Vancouver. These fees include costs incurred throughout 1996 in pursuing the
acquisition of the Energy Fuels Assets. The Registrant continues to pay monthly
fees of Cdn.$12,840 to this service company.

During the period ended September 30, 1997 the Registrant incurred interest of
$147,315 on a letter of credit and other loan facilities provided by a director
of the Registrant as part of the acquisition of the Energy Fuels assets.  This
amount has subsequently been paid and the underlying facilities have been paid
off and terminated.

The aggregate indebtedness to the Registrant or any of its subsidiaries of all
officers, directors, employees and former officers, directors and employees of
the Registrant and its subsidiaries as of May 15, 1998 is $200,000.

RIGHTS ON DISSOLUTION

<PAGE>   66



PRE-EMPTIVE AND CONVERSION RIGHTS

                                    PART IV
ITEM 17 -     FINANCIAL STATEMENTS

See Financial Statements attached.

The Registrant has not included historical financial statements of Energy Fuels
in this Registration Statement because the Acquisition involved the purchase of
idle assets rather than a ongoing business. Energy Fuels effectively had no
significant operations for the two years while it was in bankruptcy. In
addition, Energy Fuels' operations during a significant period prior to the
bankruptcy filing were limited to maintaining its properties and Mill on a stand
by basis and certain uranium sales on behalf of its affiliate, Nuexco Trading
Corporation. Shortly after the Acquisition, the Registrant began its own trading
activities and started actively mining its properties and operating the Mill to
process uranium bearing ores from third parties. Any financial information, if
available, for the period of the bankruptcy would only reflect costs relating to
maintaining and converting assets to cash and two small milling operations at
the Mill during late 1995 and early 1996 to process uranium ores on behalf of
secured creditors of the bankruptcy. For the year prior to the bankruptcy,
Energy Fuels' operations were limited to maintaining its properties and the Mill
on a stand by basis and limited sales activity on behalf of Nuexco. This
information would not reflect the active operation of the Mill and certain mines
and the trading business that the Registrant currently conducts.

ATTACHMENT - ITEM 19(a)1 - AUDITED FINANCIAL STATEMENTS
- -------------------------------------------------------------------------------


AUDITORS' REPORT

To the Directors of International Uranium Corporation

We have audited the consolidated balance sheet of International Uranium
Corporation as at September 30, 1997 and the consolidated statements of earnings
and retained earnings and cash flows for the period from incorporation through
September 30, 1997. 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 audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform an audit to obtain reasonable
assurance 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.

In our opinion, these consolidated financial statements present fairly, in all
material respects, the financial position of the Company as at September 30,
1997, and the results of its operations and the changes in its financial
position for the period then ended in accordance with generally accepted
accounting principles in Canada.

     "Mill") near Blanding, Utah. The Mill is used to process the Company's
     mined ore along with ore purchased or toll milled from other independent
     mines. The Mill is also used to process alternate feeds, which generally
     are ores or residues from other processing facilities that contain uranium
     in quantities or forms that are either uneconomic to recover or cannot be
     recovered at these other facilities, but can be economically recovered in
     conjunction with other co-products at the Mill.

2.   SIGNIFICANT ACCOUNTING POLICIES

     These consolidated financial statements have been prepared in accordance
     with accounting principles generally accepted in Canada. Differences with
     respect to accounting principles generally accepted in the United States
     are disclosed in Note 16.

     a)   Use of estimates

          The preparation of consolidated financial statements in conformity
          with generally accepted accounting principles requires the Company's
          management to make estimates and assumptions that affect the amounts
          reported in these financial statements and notes thereto. Actual
          results could differ from those estimated.

     b)   Basis of consolidation

          The consolidated financial statements include the accounts of the
          Company and its wholly-owned subsidiaries, International Uranium
          Holdings Corporation, International Uranium U.S. Finance LLC,
          International Uranium (Bermuda) Ltd., Energy Fuels Exploration Company
          Ltd., and International Uranium (USA) Corporation.

     c)   Cash and cash equivalents

          Cash and cash equivalents consist of cash on deposit and highly liquid
          short-term interest bearing securities with maturities at the date of
          purchase of three months or less.



                                       5
<PAGE>   74


     d)   Marketable securities and restricted short-term investments

          Marketable securities and restricted short term investments are valued
          at the lower of cost or market value.

     e)   Inventories

          Inventories of ore stockpiles, uranium concentrates and refined and
          converted products are valued at the lower of cost or net realizable
          value. Consumable supplies and spares are valued at the lower of
          weighted average cost or replacement value.

     f)   Properties, plant and equipment

          Mine property, plant and equipment are recorded at cost. Mine property
          is depleted by the units-of- production method based on ore reserves.
          Plant and equipment are depreciated on a straight line basis over
          their estimated useful lives from three to fifteen years.

     g)   Exploration properties

          The Company defers the property acquisition costs and ongoing
          exploration expenditures on properties still in the exploration stage
          and carries these as assets until the results of the exploration
          projects are known. If a project is successful, the cost of the
          property and the related exploration and development expenditures will
          be amortized over the life of the property utilizing the units-of-
          production method. If a project is unsuccessful, the mining property
          and the related exploration expenditure are written off.

     h)   Environmental protection and reclamation costs

          Expenditures relating to ongoing environmental and reclamation
          programs are charged against earnings as incurred or capitalized and
          depreciated depending on their relationship to future earnings. The
          estimated costs for decommissioning and reclaiming producing resource
          properties are fully accrued on an undiscounted basis. Changes in
          these cost estimates from time to time are capitalized and amortized
          to earnings on the units-of-production basis in the case of mine costs
          and on a straight line basis over 15 years in the case of mill costs.
          Actual costs of decommissioning and reclamation are deducted against
          this accrual.

     i)   Foreign currency translation

          These consolidated financial statements are denominated in United
          States dollars, the Company's functional currency. Substantially all
          of the Company's assets and operations are located in the United
          States, with the exception of the Mongolian Gurvan-Saihan Joint
          Venture (Note 8). The majority of its costs are denominated in United
          States dollars and all of its products for sale are priced in United
          States dollars.

          Amounts denominated in foreign currencies are translated into United
          States dollars as follows:

          a)   Monetary assets and liabilities at the rates of exchange in
               effect at balance sheet dates;

          b)   Non-monetary assets at historical rates;

          c)   Revenue and expense items at the average rates for the period.

          The net effect of the foreign currency translation is included in the
          statement of earnings subsequent to the acquisition.



                                       6
<PAGE>   75

     j)   Net earnings per share

          Net earnings per common share is determined using the weighted average
          number of shares outstanding during the year, which for the period
          ending September 30, 1997 was 42,067,497 shares.

     k)   Goodwill

          Goodwill is amortized on a straight-line basis over twenty years.

3.   ACQUISITION OF ENERGY FUELS ASSETS AND THE AMALGAMATION

     In May 1997, the Company completed the acquisition of substantially all of
     the uranium producing assets and assumed certain obligations of Energy
     Fuels Ltd., Energy Fuels Exploration Company and Energy Fuels Nuclear, Inc.

                                                  $34,588,223
                                                  ===========
</TABLE>

     The Energy Fuels assets included several developed mines on standby,
     several partially developed mines, as well as numerous targeted mines and
     exploration properties, within the states of Colorado, Utah, Arizona,
     Wyoming and South Dakota, as well as a 70% interest in a joint venture with
     the government of Mongolia and a Russian geological concern to develop and
     produce uranium reserves in Mongolia.

     Assets purchased also included the 2,000 ton per day White Mesa Mill near
     Blanding, Utah. The Mill also has a vanadium recovery circuit.

     Concurrent with the acquisition of Energy Fuels, in May 1997, the Company
     completed an amalgamation with Thornbury Capital Corporation ("Thornbury").
     Each of the shareholders of Thornbury received one common share in the
     amalgamated company for every five common shares held prior to the
     amalgamation and the shareholders of the Company received one common share
     for every one common share held prior to the amalgamation. As a result of
     this transaction, the shareholders of the Company acquired control of
     Thornbury, and accordingly, the transaction has been accounted for as an
     acquisition by the Company of Thornbury.

     "Venture") which holds five uranium exploration blocks covering 12,100
     square kilometers in central eastern Mongolia. The other parties are the
     Mongolian government as to 15% and Geologorazvedka a Russian geological
     concern as to 15%. A royalty in the amount of 4% is payable to the
     Mongolian government. The Company has proportionately consolidated its 70%
     interest in the Venture, which is substantially represented by exploration
     properties. To date the Company has funded all expenditures and expects to
     do so for the foreseeable future.

9.   RESTRICTED SHORT-TERM INVESTMENTS

11.  PROVISION FOR RECLAMATION

     As part of the acquisition of Energy Fuels, the Company is responsible for
     the environmental and reclamation obligations of Energy Fuels relating to
     all existing mines, the Mill, and other assets, as well as for all
     reclamation and environmental obligations associated with all mined out,
     inactive, reclaimed or partially reclaimed mines and properties, that were
     so acquired.

     The total amount of the reclamation liability has been estimated by the
     Company at $13,265,700. The Company has posted bonds in favor of the United
     States Nuclear Regulatory Commission and the applicable state regulatory
     agencies securing these liabilities and has placed $7,945,356 on account of
     the obligation (Note 9).

     Elements of uncertainty in estimating reclamation and decommissioning costs
     include potential changes in regulatory requirements, decommissioning and
     reclamation alternatives. Actual costs will differ from those estimated and
     this may be material.

     In May 1997, the Company completed a private placement financing of
     37,800,000 common shares pursuant to the exercise of special warrants that
     had been issued in March 1997 at a price of Cdn$1.25 ($0.90) per special
     warrant for net proceeds of Cdn$44,217,190 ($31,784,288), after deducting
     share issue costs and agents fees of Cdn$3,032,802 ($2,186,137).

c)   Stock options

     The Company has adopted an Employee Stock Option Plan under which the Board
     of Directors may from time to time grant to directors, officers, eligible
     employees of, or consultants to, the Company or its subsidiaries, or to
     employees of management companies providing services to the Company,
     options to acquire common shares in such numbers for such terms and at such
     exercise prices as may be determined by the Board. The purpose of the Stock
     Option Plan is to advance the interests of the Company by providing
     eligible personnel with a financial incentive for the continued improvement
     of the Company's performance and encouragement to stay with the Company.

     Options granted to executive officers and certain employees of the Company
     vest as to one-third on the date of grant, as to another one-third one year
     after the date of grant and the remainder two years after the date of
     grant. All other options vest as to one-half on the date of grant and as to
     the remainder one year after the date of grant.

     As at September 30, 1997, options were outstanding to directors, officers
     and employees to purchase 2,639,000 common shares at a price of CDN $1.25
     per share with 2,389,000 expiring May 8, 2000 and 250,000 expiring on June

          facilities provided by a director of the Company as part of the
          acquisition of Energy Fuels. This amount was paid subsequent to year
          end. The underlying facilities were paid off and terminated prior to
          year end.

14.  COMMITMENTS

     Certain Swiss utilities hold a royalty (the "Swiss Royalty") of 9% of all
     uranium and 5% of vanadium and all other minerals produced from certain of
     the United States properties. The Swiss Royalty does not apply to the
     Mongolia properties, nor to any tolled or purchased ore of or from third
     parties that is processed in the Mill, nor to any properties acquired after
     the date that the Swiss royalty was granted.

     The Company has entered into negotiations with the Swiss utilities toward
     amending certain terms of the royalty agreement.

15.  FINANCIAL INSTRUMENTS

     As at September 30, 1997, the fair value of the Company's financial
     instruments approximates their carrying values because of the short-term
     nature of these instruments and, where applicable, because interest rates
     approximate market rates.

16.  DIFFERENCES BETWEEN CANADIAN AND UNITED STATES ACCOUNTING PRINCIPLES AND
     PRACTICES

     The consolidated financial statements have been prepared in accordance with
     accounting principles and practices generally accepted in Canada (Canadian
     basis) which differ in certain respects from those principles and practices
     that the Company would have followed had its consolidated financial
     statements been prepared in accordance with accounting principles and
     practices generally accepted in the United States.

     o    Under Canadian GAAP, the amalgamation of the Company with Thornbury
          has been accounted for as an acquisition of Thornbury resulting in the
          recording of goodwill. Under U.S. GAAP, the transaction has been
          accounted for as a recapitalization whereby the net monetary assets of
          Thornbury would be recorded at fair value, except that no goodwill or
          other intangibles would be recorded. The goodwill recorded under
          Canadian GAAP has been applied to reduce the share capital of the
          Company under U.S. GAAP.

     o    Under Canadian GAAP, certain non-cash transactions are included in
          the consolidated statement of cash flows. Under U.S. GAAP, non-cash
          transactions are excluded from the consolidated statement of cash
          flows.

     These would have been reported in the consolidated balance sheet,
     consolidated statement of earnings an retained earnings, and the
     consolidated statement of cash flows as follows:

of directors determined by resolution of the board. Subject to paragraph 3.08,
the quorum for the transaction of business at any meeting of the board shall be
a majority of the number of directors then in office and or such greater number
of directors as the board may from time to time by resolution determine,
provided that if the Corporation has fewer than three directors, all directors
must be present at any meeting of the board to constitute a quorum.

3.02              Qualification

                  No person shall be qualified for election as a director if he
is less than 18 years of age; if he is of unsound mind and has been so found by
a court in Canada or elsewhere; if he is not an individual; or if he has the
status of a bankrupt. A director need not be a shareholder. A majority of the
directors shall be resident Canadians, provided that if the Corporation has only
one or two directors, that director or one of the two directors, as the case may
be, shall be a resident Canadian. If the Corporation is or becomes an offering
corporation within the meaning of the Act, at least one-third of the directors
of the Corporation shall not be officers or employees of the Corporation or any
of its affiliates.

3.03              Election and Term

                  The election of directors shall take place at the first
meeting of shareholders and at each succeeding annual meeting of shareholders
and all the directors then in office shall retire but, if qualified, shall be
eligible for re-election. The number of directors to be elected at any such
meeting shall be the number of directors as specified in the articles or, if a
minimum and maximum number of directors is provided for in the articles, the
number of directors determined by special resolution or, if the special
resolution empowers the directors to determine the number, the number of
directors determined by resolution of the board. The voting on the election
shall be by show of hands unless a ballot is demanded by any shareholder. If an
election of directors is not held at the proper time, the incumbent directors
shall continue in office until their successors are elected.

3.04              Removal of Directors

                  Subject to the provisions of the Act, the shareholders may by
ordinary resolution passed at a meeting specially called for such purpose 






<PAGE>   7
                                      -7-

filled at the same meeting failing which it may be filled by a quorum of the
directors.

the Act, resigns; he is removed from office by the shareholders in accordance
with the Act; he becomes of unsound mind and is so found by a court in Canada or
elsewhere or if he acquires the status of a bankrupt.

3.06              Vacancies

                  Subject to the Act, a quorum of the board may fill a vacancy
in the board, except a vacancy resulting from an increase in the number or
maximum number of directors or from a failure of the shareholders to elect the
number of directors required to be elected at any meeting of shareholders. In
the absence of a quorum of the board, or if the vacancy has arisen from a
failure of the shareholders to elect the number of directors required to be
elected at any meeting of shareholders, the directors then in office shall
forthwith call a special meeting of shareholders to fill the vacancy. If the
directors then in office fail to call such meeting or if there are no directors
then in office, any shareholder may call the meeting.

3.07              Action by the Board

                  The board shall manage or supervise the management of the
business and affairs of the Corporation. Subject to paragraphs 3.08 and 3.09,
the powers of the board may be exercised at a meeting at which a quorum is
present or by resolution in writing signed by all the directors entitled to vote
on that resolution at a meeting of the board. Where there is a vacancy in the
board, the remaining directors may exercise all the powers of the board so long
as a quorum of the board remains in office.

3.08              Canadian Majority

                  The board shall not transact business at a meeting other than
to fill a vacancy in the board, unless a majority of the directors present are
resident Canadians, except where

         (a)      a resident Canadian director who is unable to be present
                  approves in writing or by telephone or other communications
                  facilities the business transacted at the meeting; and

         (b)      a majority of resident Canadians would have been present had
                  that director been present at the meeting.

3.09              Meeting by Telephone

                  If all the directors of the Corporation present or
participating in the meeting consent, a director may participate in a meeting of
the board or of a committee of the board by means of such telephone, electronic
or other communications facilities as permit all persons participating in the
meeting to communicate with each other simultaneously and instantaneously, and a
director participating in such a meeting by such means is deemed to be present
at the meeting. Any such consent shall be effective whether given before or
after the meeting to which it relates and may be given with respect to all
meetings of the board and of committees of the board held while a director holds
office.

3.10              Place of Meetings

                  Meetings of the board may be held at any place within or
outside Ontario. In any financial year of the Corporation a majority of the

consent to a meeting of the board.

3.13              First Meeting of New Board

3.14              Adjourned Meeting

                  Notice of an adjourned meeting of the board is not required if

                  The Chairman of the Board, if appointed, shall be a director

board, shall have general supervision of the business and affairs of the
Corporation and such other powers and duties as the board may specify. The
President shall be vested with and may exercise all the powers and shall perform
all the duties of the Chairman of the Board if none be appointed or if the
Chairman of the Board is absent or unable or refuses to act.

5.04              Vice-President

                  Each Vice-President shall have such powers and duties as the

mechanical device generally used for affixing the corporate seal of the
Corporation and all books, papers, records, documents and instruments belonging
to the Corporation, except when some other officer or agent has been appointed
for that purpose; and he shall have such other powers and duties as the board
may specify.

5.06              Treasurer

                  The Treasurer shall keep proper accounting records in
compliance with the Act and shall be responsible for the deposit of money, the
safekeeping of securities and the disbursement of the funds of the Corporation;
he shall render to the board whenever required an account of all his
transactions as Treasurer and of the financial position of the Corporation; and
he shall have such other powers and duties as the board may specify. Unless and
until the board designates any other officer of the Corporation to be the Chief
Financial Officer of the Corporation, the Treasurer shall be the Chief Financial
Officer of the Corporation.

5.07              Powers and Duties of Other Officers

                  The powers and duties of all other officers shall be such as

exercised and performed by such assistant, unless the board otherwise directs.

                  The terms of employment and the remuneration of an officer

any officer or employee is a director or shareholder of the Corporation shall
not disqualify him from receiving such remuneration as may be so determined.

fit.

                  The board may require such officers, employees and agents of
the Corporation as the board deems advisable to furnish bonds for the faithful
discharge of their powers and duties, in such form and with such surety as the
board may from time to time determine but no director shall be liable for
failure to require any such bond or for the insufficiency of any such bond or
for any loss by reason of the failure of the Corporation to receive any
indemnity thereby provided.


                                   SECTION SIX

                                  PROTECTION OF

                  The board in its discretion may submit any contract, act or
transaction for approval, ratification or confirmation at any meeting of the
shareholders called for the purpose of considering the same and any contract,
act or transaction that shall be approved, ratified or confirmed by a resolution
passed by a majority of the votes cast at any such meeting (unless any different
or additional requirement is imposed by the Act or by the Corporation's articles
or any other by-law) shall be as valid and as binding upon the Corporation and
upon all the shareholders as though it had been approved, ratified or confirmed
by every shareholder of the Corporation.

6.02              For the Protection of Directors and Officers

                  In supplement of and not by way of limitation upon any rights
conferred upon directors by the provisions of the Act, it is declared that no
director shall be disqualified by his office from, or vacate his office by
reason of, holding any office or place of profit under the Corporation or under
any body corporate in which the Corporation shall be a shareholder or by reason
of being otherwise in any way directly or indirectly interested or contracting
with the Corporation either as vendor, purchaser or otherwise or being concerned
in any contract or arrangement made or proposed to be entered into with the
Corporation in which he is in any way directly or indirectly interested either
as vendor, purchaser or otherwise nor shall any director be liable to account to
the Corporation or any of its shareholders or creditors for any profit arising
from any such office or place of profit; and, subject to the provisions of the
Act, no contract or arrangement entered into by or on behalf of the Corporation
in which any director shall be in any way directly or indirectly interested
shall be avoided or voidable and no director shall be liable to account to the
Corporation or any of its shareholders or creditors for any profit realized by
or from any such contract or arrangement by reason of the fiduciary relationship
existing or established thereby. Subject to the provisions of the Act and to
paragraph 3.18, no director shall be obliged to make any declaration of interest
or refrain from voting in respect of a contract or proposed contract with the
Corporation in which such director is in any way directly or indirectly
interested.

6.03              Limitation of Liability

                  Except as otherwise provided in the Act, no director or
officer for the time being of the Corporation shall be liable for the acts,
receipts, neglects or defaults of any other director or officer or employee or
for joining in any receipt or act for conformity or for any loss, damage or
expense happening to the Corporation through the insufficiency or deficiency of
title to any property acquired by the Corporation or for or on behalf of the
Corporation or for the insufficiency or deficiency of any security in or upon
which any of the moneys of or belonging to the Corporation shall be placed out
or invested or for any loss or damage arising from the bankruptcy, insolvency or
tortious act of any persons, firm or corporation including any person, firm or
corporation with whom or which any moneys, securities or effects shall be lodged
or deposited for any loss, conversion, misapplication or misappropriation of or
any damage resulting from any dealings with any moneys, securities or other
assets belonging to the Corporation or for any other loss, damage or 
<PAGE>   16

                                      -16-


misfortune whatever which may happen in the execution of the duties of his
respective office or trust or in relation thereto unless the same shall happen
by or through his failure to exercise the powers and to discharge the duties of
his office honestly, in good faith and in the best interests of the Corporation
and in connection therewith to exercise the degree of care, diligence and skill
that a reasonably prudent person would exercise in comparable circumstances. The
directors for the time being of the Corporation shall not be under any duty or
responsibility in respect of any contract, act or transaction whether or not
made, done or entered into in the name or on behalf of the Corporation, except
such as shall have been submitted to and authorized or approved by the board. If
any director or officer of the Corporation shall be employed by or shall perform
services for the Corporation otherwise than as a director or officer or shall be
a member of a firm or a shareholder, director or officer of a company which is
employed by or performs services for the Corporation, the fact of his being a
director or officer of the Corporation shall not disentitle such director or
officer or such firm or company, as the case may be, from receiving proper
remuneration for such services.

6.04              Indemnity

                  Subject to the limitations contained in the Act, the
Corporation shall indemnify a director or officer, a former director or officer,
or a person who acts or acted at the Corporation's request as a director or
officer of a body corporate of which the Corporation is or was a shareholder or
creditor, and his heirs and legal representatives, against all costs, charges
and expenses, including an amount paid to settle an action or satisfy a
judgment, reasonably incurred by him in respect of any civil, criminal or
administrative action or proceeding to which he is made a party by reason of
being or having been a director or officer of the Corporation or such body
corporate, if

         (a)      he acted honestly and in good faith with a view to the best
                  interest of the Corporation; and

         (b)      in the case of a criminal or administrative action or
                  proceeding that is enforced by a monetary penalty, he had
                  reasonable grounds for believing that his conduct was lawful.

The Corporation shall also indemnify such person in such other circumstances as
the Act permits or requires.

6.05              Insurance

                  The Corporation may purchase and maintain insurance for the
benefit of any person referred to in paragraph 6.04 against such liabilities and

by the Act.

Corporation at such times and to such persons and for such consideration as the
board shall determine, provided that no share shall be issued until it is fully
paid as provided by the Act.

7.02              Commissions

                  The board may from time to time authorize the Corporation to

from any other person, or procuring or agreeing to procure purchasers for any
such shares.

7.03              Registration of Transfers

                  Subject to the provisions of the Act, no transfer of shares
shall be registered in a securities register except upon presentation of the
certificate representing such shares with an endorsement which complies with the
Act made thereon or delivered therewith duly executed by an appropriate person
as provided by the Act, together with such reasonable assurance that the
endorsement is genuine and effective as the board may from time to time
prescribe, upon payment of all applicable taxes and any fees prescribed by the
board, upon compliance with such restrictions on transfer as are authorized by
the articles and upon satisfaction of any lien referred to in paragraph 7.05.

7.04              Transfer Agents and Registrars

                  The board may from time to time appoint one or more agents to

7.05              Lien for Indebtedness

                  The Corporation shall have a lien on any share registered in
the name of a shareholder or his legal representatives for a debt of that
shareholder to the Corporation, provided that if the shares of the Corporation
are listed on a stock exchange recognized by the Ontario Securities Commission,
the Corporation shall not have such lien. The Corporation may enforce any lien
that it has on shares registered in the name of a shareholder indebted to the
Corporation by the sale of the shares thereby affected or by any other action,
suit, remedy or proceeding authorized or permitted by law and, pending such
enforcement, the Corporation may refuse to register a transfer of the whole or
any part of such shares.

7.06              Non-recognition of Trusts

                  Subject to the provisions of the Act, the Corporation may
treat as absolute owner of any share the person in whose name the share is
registered in the securities register as if that person had full legal capacity
and authority to exercise all rights of ownership, irrespective of any
indication to the contrary through knowledge or notice or description in the
Corporation's records or on the share certificate.

7.07              Share Certificates

                  Every holder of one or more shares of the Corporation shall be
entitled, at his option, to a share certificate, or to a non-transferable
written acknowledgement of his right to obtain a share certificate, stating the
number and class or series of shares held by him as shown on the securities
register. Share certificates and acknowledgements of a shareholder's right to a
share certificate, respectively, shall be in such form as the board shall from
time to time approve. Any share certificate shall be signed in accordance with
paragraph 2.03 and need not be under the corporate seal; provided that, unless
the board otherwise determines, certificates representing shares in respect of
which a transfer agent and/or registrar has been appointed shall not be valid
unless countersigned by or on behalf of such transfer agent and/or registrar.
The signature of one of the signing officers or, in the case of share
certificates which are not valid unless countersigned by or on behalf of a
transfer agent and/or registrar, the signatures of both signing officers, may be
printed or mechanically reproduced in facsimile upon share certificates and
every such facsimile signature shall for all purposes be deemed to be the
signature of the officer whose signature it reproduces and shall be binding upon
the Corporation. A share certificate executed as aforesaid shall be valid
<PAGE>   19

                                      -19-



notwithstanding that one or both of the officers whose facsimile signature
appears thereon no longer holds office at the date of issue of the certificate.


7.08              Replacement of Share Certificates

                  The board or any officer or agent designated by the board may
in its or his discretion direct the issue of a new share certificate in lieu of
and upon cancellation of a share certificate that has been mutilated or in
substitution for a share certificate claimed to have been lost, destroyed or
wrongfully taken on payment of such fee, not exceeding $3.00, and on such terms
as to indemnity, reimbursement of expenses and evidence of loss and of title as
the board may from time to time prescribe, whether generally or in any
particular case.

7.09              Joint Shareholders

                  If two or more persons are registered as joint holders of any
share, the Corporation shall not be bound to issue more than one certificate in
respect thereof, and delivery of such certificate to one of such persons shall
be sufficient delivery to all of them. Any one of such persons may give
effectual receipts for the certificate issued in respect thereof or for any
dividend, bonus, return of capital or other money payable or warrant issuable in
respect of such shares.

7.10              Deceased Shareholders

                  In the event of the death of a holder, or of one of the joint
holders, of any share, the Corporation shall not be required to make any entry
in the securities register in respect thereof or to make payment of any
dividends thereon except upon production of all such documents as may be
required by law and upon compliance with the reasonable requirements of the
Corporation and its transfer agents.

the Corporation's bankers or one of them to the order of each registered holder
of shares of the class or series in respect of which it has been declared and
mailed by prepaid ordinary mail to such registered holder at his recorded
address, unless such holder otherwise directs. In the case of joint holders the
cheque shall, unless such joint holders otherwise direct, be made payable to the
order of all of such joint holders and mailed to them at their recorded address.
The mailing of such cheque as aforesaid, unless the same is not paid on due
presentation, shall satisfy and discharge the liability for the dividend to the
extent of the sum represented thereby plus the amount of any tax which the
Corporation is required to and does withhold.

8.03              Non-receipt of Cheques

                  In the event of non-receipt of any dividend cheque by the
person to whom it is sent as aforesaid, the Corporation shall issue to such
person a replacement cheque for a like amount on such terms as to indemnity,
reimbursement of expenses and evidence of non-receipt and of title as the board
may from time to time prescribe, whether generally or in any particular case.

8.04              Record Date for Dividends and Rights

                  The board may fix in advance a date, preceding by not more
than 50 days the date for the payment of any dividend or the date for the issue
of any warrant or other evidence of the right to subscribe for securities of the
Corporation, as a record date for the determination of the persons entitled to
receive payment of such dividend or to exercise the right to subscribe for such
securities, and notice of any such record date shall be given not less than
seven days before such record date in the manner provided by the Act. If no
record date is so fixed, the record date for the determination of the persons
entitled to receive payment of any dividend or to exercise the right to
subscribe for securities of the Corporation shall be at the close of business on
the day on which the resolution relating to such dividend or right to subscribe
is passed by the board.

                  Any dividend unclaimed after a period of six years from the
date on which the same has been declared to be payable shall be forfeited and
shall revert to the Corporation.


                                  SECTION NINE

election of directors and reappointment of the incumbent auditor shall state or
be accompanied by a statement of the nature of such business in sufficient
detail to permit the shareholder to form a reasoned judgment thereon and the

may in any manner waive notice of or otherwise consent to a meeting of
shareholders.

9.05              List of Shareholders Entitled to Notice

                  For every meeting of shareholders, the Corporation shall 
prepare a list of shareholders entitled to receive notice of the meeting,
arranged in alphabetical order and showing the number of shares held by each
shareholder entitled to vote at the meeting. If a record date for the meeting is
fixed pursuant to paragraph 9.06, the shareholders listed shall be those
registered at the close of business on such record date. If no record date is
fixed, the shareholders listed shall be those registered at the close of
business on the day immediately preceding the day on which notice of the meeting
is given, or where no such notice is given, the day on which the meeting is
held. The list shall be available for examination by any shareholder during
usual business hours at the registered office of the Corporation or at the place
where the central securities register is maintained and at the meeting for which
the list was prepared.

meeting of shareholders by not more than 50 days and not less than 21 days, as a
record date for the determination of the shareholders entitled to notice of the
meeting, provided that notice of any such record date shall be given not less
than seven days before such record date by newspaper advertisement in the manner

         (a)      if all the shareholders entitled to vote thereat are present
                  in person or represented by proxy waive notice of or otherwise
                  consent to such meeting being held, and

         (b)      if the auditor and the directors are present or waive notice
                  of or otherwise consent to such meeting being held, so long as
                  such shareholders, auditor and directors present are not
                  attending for the express purpose of objecting to the
                  transaction of any business on the grounds that the meeting is
                  not lawfully called. At such a meeting any business may be
                  transacted which the Corporation at a meeting of shareholders
                  may transact. If the meeting is held at a place outside
                  Canada, shareholders not present or represented by proxy, but
                  who have waived notice of or otherwise consented to such
                  meeting, shall also be deemed to have consented to the meeting
                  being held at such place.

                  The chairman of any meeting of shareholders shall be the first
mentioned of such of the following officers as have been appointed and who is
present at the meeting: the President or a Vice-President who is a director and
a shareholder. If no such officer is present within 15 minutes from the time
fixed for holding the meeting, the persons present and entitled to vote shall
choose one of their number to be chairman. If the Secretary of the Corporation
is absent, the chairman shall appoint some person, who need not be a
shareholder, to act as secretary of the meeting. If desired, one or more
scrutineers, who need not be shareholders, may be appointed by a resolution or
by the chairman with the consent of the meeting.

9.09              Persons Entitled to be Present

                  The only persons entitled to be present at a meeting of
shareholders shall be those entitled to vote thereat, the directors and the
auditor of the Corporation and others who, although not entitled to vote are
entitled or required under any provision of the Act or the articles or the
by-laws to be present at the meeting. Any other person may be admitted only on
the invitation of the chairman of the meeting or with the consent of the
meeting.

9.10              Quorum

                  Subject to section 9.20 of this by-law, a quorum for the

present in person, each being a shareholder entitled to vote thereat or a duly
appointed proxy or proxyholder for an absent shareholder so entitled, holding or
representing in the aggregate not less than 10% of the issued shares of the
Corporation enjoying voting rights at such meeting.

9.11              Right to Vote

                  Subject to the provisions of the Act as to authorized
representatives of any other body corporate or association, at any meeting of
shareholders for which the Corporation has prepared the list referred to in
paragraph 9.05, every person who is named in such list shall be entitled to vote
the shares shown opposite his name except to the extent that such person has
transferred any of his shares after the record date determined in accordance
with paragraph 9.06 and the transferee, having produced properly endorsed
certificates evidencing such shares or having otherwise established that he owns
such shares, has demanded not later than 10 days before the meeting that his
name be included in such list. In any such case the transferee shall be entitled
to vote the transferred shares at the meeting. At any meeting of shareholders
for which the Corporation has not prepared the list referred to in paragraph
9.05, every person shall be entitled to vote at the meeting who at the time is
entered in the securities register as the holder of one or more shares carrying
the right to vote at such meeting.

                                      -25-



9.12              Proxies

                  Every shareholder entitled to vote at a meeting of
shareholders may appoint a proxyholder, or one or more alternate proxyholders,
who need not be shareholders, to attend and act at the meeting in the manner and
to the extent authorized and with the authority conferred by the proxy. A proxy
shall be in writing executed by the shareholder or his attorney authorized in
writing and shall conform with the requirements of the Act.

9.13              Time for Deposit of Proxies

                  The board may by resolution specify in a notice calling a
meeting of shareholders a time, preceding the time of such meeting or an
adjournment thereof by not more than 48 hours exclusive of any part of a
non-business day, before which time proxies to be used at such meeting must be
deposited. A proxy shall be acted upon only if, prior to the time so specified,
it shall have been deposited with the Corporation or an agent thereof specified
in such notice or, if no such time is specified in such notice, only if it has
been received by the Secretary of the Corporation or by the chairman of the
meeting or any adjournment thereof prior to the time of voting.

9.14              Joint Shareholders

                  If two or more persons hold shares jointly, any one of them
present in person or represented by proxy at a meeting of shareholders may, in
the absence of the other or others, vote the shares; but if two or more of those
persons are present in person or represented by proxy and vote, they shall vote
as one the shares jointly held by them.

9.15              Votes to Govern

                  At any meeting of shareholders every question shall, unless
otherwise required by the articles or by-laws or by law, be determined by a
majority of the votes cast on the question. In case of an equality of votes
either upon a show of hands or upon a poll, the chairman of the meeting shall
not be entitled to a second or casting vote.

9.16              Show of Hands

                  Subject to the provisions of the Act, any question at a
meeting of shareholders shall be decided by a show of hands unless a ballot
thereon is required or demanded as hereinafter provided. Upon a 

<PAGE>   26

                                      -26-


show of hands every person who is present and entitled to vote shall have one
vote. Whenever a vote by show of hands shall have been taken upon a question,
unless a ballot thereon is so required or demanded, a declaration by the
chairman of the meeting that the vote upon the question has been carried or
carried by a particular majority or not carried and an entry to that effect in
the minutes of the meeting shall be prima facie evidence of the fact without
proof of the number or proportion of the votes recorded in favour of or against
any resolution or other proceeding in respect of the said question, and the
result of the vote so taken shall be the decision of the shareholders upon the
said question.

9.17              Ballots

                  On any question proposed for consideration at a meeting of
shareholders, and whether or not a vote by show of hands has been taken thereon,
any shareholder or proxyholder entitled to vote at the meeting may require or
demand a ballot. A ballot so required or demanded shall be taken in such manner
as the chairman shall direct. A requirement or demand for a ballot may be
withdrawn at any time prior to the taking of the ballot. If a ballot is taken
each person present shall be entitled, in respect of the shares which he is
entitled to vote at the meeting upon the question, to that number of votes
provided by the Act or the articles, and the result of the ballot so taken shall
be the decision of the shareholders upon the said question.

9.18              Adjournment

                  The chairman at the meeting of shareholders may with the
consent of the meeting and subject to such conditions as the meeting may decide,
or where otherwise permitted under the provisions of the Act, adjourn the
meeting from time to time and from place to place. If a meeting of shareholders
is adjourned for less than 30 days, it shall not be necessary to give notice of
the adjourned meeting, other than by announcement at the earliest meeting that
is adjourned. If a meeting of shareholders is adjourned by one or more
adjournments for an aggregate of 30 days or more, notice of the adjourned
meeting shall be given as for an original meeting.

9.19              Resolution in Writing

                  A resolution in writing signed by all the shareholders
entitled to vote on that resolution at a meeting of shareholders is as valid as
if it had been passed at a meeting of the shareholders unless a written

                                      -27-



statement with respect to the subject matter of the resolution is submitted by a
director or the auditor in accordance with the Act.

                  Except as provided by the Act, no shareholder shall be

inexpedient in the interests of the Corporation to communicate to the public.

10.02             Directors' Determination

                  The directors may from time to time, subject to the rights

to the inspection of shareholders and no shareholder shall have any right to
inspect any document or book or register or accounting record of the Corporation
except as conferred by statute or authorized by the board or by a resolution of
the shareholders in general meeting.

under any provision of the Act, the regulations thereunder, the articles, the

after the meeting or other event of which notice is required to be given shall
cure any default in the giving or in the time of such notice, as the case may
be. Any such waiver or abridgement shall be in writing except a waiver of notice
of a meeting of shareholders or of the board or of a committee of the board
which may be given in any manner.

                           transactions contemplated by this Agreement or which
                           would render inaccurate any of the representations or

warrant indenture (the "Special Warrant Indenture") to be dated as of the
Closing Date and made between the Company and the Warrant Agent as warrant
agent thereunder.

2.2      The Special Warrant Indenture shall contain provisions substantially
to the effect that:

(a)      each Special Warrant will entitle the holder thereof, upon the
         exercise thereof and without payment of any additional consideration,
         to be issued one Common Share, subject to adjustment as provided in
         the Special Warrant Indenture;

(b)      each holder of Special Warrants will be entitled to exercise its
         Special Warrants during the period commencing on the Closing Date and
         ending at the Expiry Time;

(c)      if the Deemed Exercise Time does not occur prior to the Automatic
         Retraction Time, the Special Warrants then outstanding will
         automatically and immediately thereafter be retracted by the Warrant
         Agent on behalf of the holders thereof for repayment to such holders
         out of the Escrow Funds of the aggregate Purchase Price for such
         retracted Special Warrants together with payment of an amount equal to

         from the Closing Date to and including the day immediately preceding
         the date of payment to such holder.

(d)      any Special Warrant not exercised prior to the Deemed Exercise Time
         will be exercised at the Deemed Exercise Time by the Warrant Agent on
         behalf of the holder thereof (without any further action on the part
         of the holder thereof or the Company) subject to applicable securities
         laws; and





                                     - 5 -

<PAGE>   6
(e)      upon the satisfaction of the Escrow Release Conditions, the Company
         and the Agents will forthwith, and in any event not later than the
         first business day thereafter, give written notice thereof to the
         Warrant Agent and the Warrant Agent will forthwith give written notice
         thereof to the holders of Special Warrants.

2.3      The provisions of the Special Warrant Indenture and the attributes and
characteristics of the Special Warrants provided for therein shall be
substantially as described herein, with such changes thereto as the Agents and
the Company may agree to, and otherwise the Special Warrant Indenture shall be
in such form and contain such terms and provisions (including customary
anti-dilution provisions) as are satisfactory to the Company and the Agents,
acting reasonably.

3.       NATURE OF TRANSACTION

3.1      The offering and sale of the Special Warrants to Purchasers is to be
effected in a manner exempt from any prospectus filing or delivery requirements
of all securities laws and policies applicable in the various jurisdictions in
which the Special Warrants are offered for sale and sold, without the necessity
of obtaining any order or ruling of any securities regulatory authority.
Accordingly, each Purchaser shall purchase Special Warrants from the Company,
insofar as the laws of the Province of Ontario are concerned, under prospectus
filing exemptions contained in paragraphs 72(1)(a), (c) or (d) of the
Securities Act (Ontario) and, insofar as the laws of other Selling
Jurisdictions are concerned, under similar exemptions, if available, provided
for in the applicable securities legislation of such Selling Jurisdictions (the
"Exemptions").  The Agents will notify the Company with respect to the identity
and jurisdiction of residence of each Purchaser as soon as practicable (and in
any event not later than the business day prior to the Closing Date) and with a
view to affording sufficient time to allow the Company to secure compliance
with all applicable regulatory requirements in connection with the sale of the
Special Warrants to Purchasers under the Exemptions.

3.2      The Company shall at its expense comply with all applicable regulatory
requirements of the Selling Jurisdictions in connection with the sale of the
Special Warrants to the Purchasers under the Exemptions, including the filing
of any required reports (without, if and to the extent permitted, the
disclosure therein of the names and addresses of the Purchasers) and the
payment of applicable fees relating thereto.

3.3      The Agents shall conduct their activities (and shall require any agent
appointed as contemplated on page 1 hereof to agree with the Agents, for the
benefit of the Company, to conduct its activities) in connection with the
distribution of the Special Warrants in compliance with all applicable laws and
regulatory requirements and, without limiting the foregoing, the Agents
represent and agree (and shall require any such agent to agree with the Agents
for the benefit of the Company) that:

(a)      all solicitation, offering and other selling efforts carried out by
         the Agents in connection with the distribution of the Special Warrants
         have been and will be


                                    - 6 -
<PAGE>   7
         made, and all purchases of Special Warrants will be made, in
         accordance with the provisions of the Exemptions in a manner such that
         no prospectus need be prepared and filed or delivered by the Company
         in connection therewith;

(b)      no advertising of the Special Warrants has been or will be made by the
         Agents in any media whatsoever (other than by way of "tombstone"
         announcement appearing as a matter of record only after the Closing);

(c)      a copy of the Offering Memorandum will be delivered to each
         prospective purchaser or Purchaser and no delivery has been or will be
         made by the Agents to any prospective purchaser or Purchaser of any
         other document which, individually or together with any other
         document, would constitute an offering memorandum (as such term is
         defined in subsection 32(1) of the Regulation to the Securities Act
         (Ontario)); and

(d)      no solicitation, offering or other selling efforts with respect to the
         distribution of the Special Warrants have been or will be made by the
         Agents in the United States or to any U.S. Person (as such term is
         defined in Regulation S under the United States Securities Act of
         1933, as amended) except in accordance with the terms and conditions
         of Schedule A attached hereto, which terms and conditions are
         incorporated herein by reference;

provided that, for greater certainty, the Company acknowledges that any term
sheet relating to the Special Warrants, annual and quarterly reports, material
change reports and press releases issued by the Company and generally available
research reports, memoranda and other materials concerning the Company,
Thornbury or Energy Fuels prepared by others do not, individually or
collectively, constitute an offering memorandum for purposes of subparagraph
(c) above.

3.4      The Agents shall obtain from each Purchaser a properly completed and
duly executed Subscription Agreement in accordance with the provisions of this
Agreement.  In order to facilitate organization for the Closing, the Agents
will use their reasonable best efforts to provide copies of such documents to
the Company's Counsel not less than 24 hours prior to the Closing Time,
provided that no provision of such documents shall constitute a delivery
thereof for purposes of paragraph 6.2 hereof.

4.       REPRESENTATIONS AND WARRANTIES OF COMPANY

4.1      Subject to paragraph 4.2, the Company represents and warrants to the
Agents and the Purchasers, and acknowledges that the Agents will be relying
upon such representations and warranties in rendering their services hereunder
and the Purchasers will be relying upon such representations and warranties in

8.       ADDITIONAL COVENANTS

8.1      The Company covenants with the Agents as follows:

(a)      prior to the completion of the Amalgamation and the Acquisition, the
         Company will allow the Agents to conduct all due diligence
         investigations and examinations which the Agents may require in order
         to satisfy themselves with respect thereto; and

(b)      from and after the date hereof until the later of completion of the
         distribution of the Underlying Shares and the completion of the
         Amalgamation and the Acquisition, the Company will promptly notify the
         Agents (which notification will be confirmed in writing if reasonably
         requested) of any material change or any change in a material fact, in
         either case whether actual, anticipated, contemplated or threatened,
         or any event or development involving a prospective material change,
         in any or all of the business, affairs, ownership, management,
         operations, assets (including information or data relating to the
         estimated or book value of assets), liabilities (contingent or
         otherwise), financial condition, capital, prospects or viability of
         the Company and its Material Subsidiaries, taken as a whole (taking
         into account the fact that the Company intends to complete the
         Amalgamation and the Acquisition) or of any change which is of such a
         nature as to result in, or which could result in, a misrepresentation
         in the Offering Memorandum.  The Company will promptly, and in any
         event within any applicable time limitation, comply with all filing
         and other requirements under the Securities Laws applicable to the
         Company as a result of any such change, event or development, provided
         that the Company shall not file or distribute any amendment to the
         Offering Memorandum without first obtaining from the Agents their
         approval as to the form and content thereof, such approval not to be
         unreasonably withheld.  In addition to the foregoing, the Company will
         in good faith discuss with the Agents any event or change in
         circumstances which is of such a nature that there is or ought to be
         consideration given by the Company as to whether notice of such event
         or change need be given to the Agents pursuant to this subparagraph.

8.2      The Company covenants with the Agents and the Purchasers as follows:

(a)      the Company will apply for, and will use its reasonable best efforts
         to obtain, conditional approval of the listing of the common shares of
         Amalgamated IUC on The Toronto Stock Exchange;

(b)      from and after the date hereof until the completion of the
         distribution of the Underlying Shares, the Company will not, and will
         not permit any of the Material Subsidiaries to, agree to any material
         supplement or amendment to the Amalgamation Agreement or the
         Acquisition Agreement that results in or could


                                   - 18 -
<PAGE>   19
         result in a misrepresentation in the Offering Memorandum without in
         good faith consulting with the Agents in respect of any such
         supplement or amendment;

(c)      to the extent that the funds deposited with and held in escrow by the
         Warrant Agent pursuant to paragraph 6.2 hereof are not sufficient to
         enable the Warrant Agent to make any required payment to the holders
         of Special Warrants upon the automatic retraction of such Special
         Warrants, the Company will, within one business day of receipt of
         notice from the Warrant Agent specifying such deficiency, provide the
         Warrant Agent with sufficient funds to enable the Warrant Agent to
         make such payment in full;

(d)      the Company will apply the proceeds from the sale of the Special
         Warrants substantially in the manner set forth in the Offering
         Memorandum in connection with the closing of the Acquisition, and as
         to the balance of such proceeds, the Offering Memorandum provides an
         accurate statement of management's current intention (it being
         acknowledged that such intention may change depending on a number of
         factors that may affect the Company's business including, without
         limitation, the price of uranium); and

(e)      from the date hereof until six months after the Closing Date, the
         Company shall not, without the prior written consent of the Agents
         (such consent not to be unreasonably withheld), directly or
         indirectly, allot, issue, offer, sell or grant any option or other
         right to purchase, or agree, become bound or announce any intention to
         allot, issue, offer, sell or grant any option or other right to
         purchase, any Common Shares (or any financial instruments or other
         securities convertible into or exchangeable or exercisable for Common
         Shares) other than as contemplated hereby or in connection with the
         Company's director, officer, employee and consultant stock option
         plans or in connection with existing agreements regarding interests in
         mineral properties.

For greater certainty, each of the foregoing covenants shall apply to
Amalgamated IUC and with respect to the common shares of Amalgamated IUC after
the Amalgamation Date.

9.       PAYMENT OF EXPENSES

9.1      Subject to paragraph 9.2, the Company shall pay or cause to be paid
all expenses of or incidental to the issuance and sale of the Special Warrants
and the distribution of the Underlying Shares and all other matters in
connection with the transactions contemplated hereby and the Amalgamation and
the Acquisition Transactions, including, without limitation, the reasonable
out-of-pocket expenses from time to time incurred by or on behalf of the Agents
(including the reasonable fees and disbursements (and taxes thereon) of the
Agents' Counsel and any local counsel

Fuels up to a maximum of $100,000 plus applicable Goods and Services taxes).

9.2      In the event the Closing occurs but the Escrow Release Conditions are
not satisfied prior to the Automatic Retraction Time, the Agents shall be
responsible for payment of their out-of-pocket expenses (including fees and
disbursements of Agents' Counsel and any local counsel retained by it to assist
in due diligence concerning Energy Fuels).

10.      INDEMNITY

10.1     The Company, which for the purposes of this section 10, shall be
deemed to include Amalgamated IUC, shall indemnify and save the Agents and each
of the Agents' shareholders, directors, officers, employees and agents
(collectively, in this section 10, the "Indemnified Persons"), harmless against
and from all liabilities, claims, demands, losses (other than losses of profit
in connection with the distribution of the Special Warrants), costs, damages
and expenses to which any of the Indemnified Persons may be subject or which
any of the Indemnified Persons may suffer or incur, whether under the
provisions of any statute or otherwise, in any way caused by, or arising
directly or indirectly from or in consequence of:

(a)      any misrepresentation or alleged misrepresentation (except a
         misrepresentation relating solely to the Agents) contained in the
         Offering Memorandum or any document filed on or before the
         Amalgamation Date with the Ontario Securities Commission or any other

(b)      any prohibition or restriction of trading in the securities of the
         Company or Amalgamated IUC or any prohibition or restriction affecting
         the distribution of the Special Warrants or the Underlying Shares or
         the common shares of Amalgamated IUC imposed by the Ontario Securities
         Commission or any other competent authority if such prohibition or

(c)      any order made or any inquiry, investigation (whether formal or

(d)      any breach of, default under or non-compliance by the Company or any
         of the Material Subsidiaries or by Amalgamated IUC with any
         representation, warranty, covenant, term or condition of the
         Amalgamation Agreement or the Acquisition Agreement or the Principal
         Documents or of any agreement or instrument relating to the
         transactions contemplated thereby or with any requirement of
         applicable securities legislation.

10.2     If any claim contemplated by paragraph 10.1 hereof shall be asserted
against any of the Indemnified Persons in respect of which indemnification is
or might reasonably be considered to be provided for in such paragraph, such
Indemnified Person shall notify the Company as soon as possible of the nature
of such claim (provided that any failure to so notify shall not affect the
Company's liability hereunder) and the Company shall be entitled (but not
required) to assume the defence of any suit brought to enforce such claim,
provided however, that the defence shall be through legal counsel selected by
the Company and reasonably acceptable to the Indemnified Person and that no
settlement may be made by the Company or the Indemnified Person without the
prior written consent of the other, such consent not to be unreasonably
withheld.  The Indemnified Person shall have the right to retain its own
counsel in any proceeding relating to a claim contemplated by paragraph 10.1
hereof if:

(a)      the Indemnified Person has been advised by counsel that there may be
         legal defences available to the Indemnified Person which are different
         from or additional to defences available to the Company (in which case
         the Company shall not have the right to assume the defence of such
         proceedings on the Indemnified Person's behalf);

(b)      the Company shall not have taken the defence of such proceedings and
         employed counsel within ten days after notice of commencement of such
         proceedings; or

(c)      the employment of such counsel has been authorized by the Company in
         connection with the defence of such proceedings;

and, in any such event, the reasonable fees and expenses of such Indemnified
Person's counsel shall be paid by the Company.

10.3     In order to provide for just and equitable contribution in
circumstances in which the indemnification provided for in this Agreement is
due in accordance with its terms but is, for any reason, held by a court to be
unavailable from the Company, each of the Company and the Indemnified Person
seeking indemnification shall contribute to the aggregate liabilities, claims,
demands, losses (other than losses of profit in connection with the
distribution of the Special Warrants), costs, damages and expenses (including





                                     - 21 -

<PAGE>   22
legal or other expenses reasonably incurred in connection with investigation or
defence of the same) to which they may be subject or which they may suffer or
incur:

(a)      in such proportion as is appropriate to reflect the relative benefits
         received by the Company on the one hand, and by the Indemnified Person
         seeking indemnity on the other hand, from the sale of the Special
         Warrants; or

(b)      if the allocation provided by subparagraph (a) above is not permitted
         by applicable law, in such proportion as is appropriate to reflect not
         only the relative benefits referred to in subparagraph (a) above but
         also to reflect the relative fault of the Indemnified Person seeking
         indemnity, on the one hand, and the Company and other applicable
         parties, on the other hand, in connection with the statements or
         omissions or other matters which resulted in such liabilities, claims,
         demands, losses, costs, damages or expenses as well as any other
         relevant equitable considerations.

The relevant benefits received by the Company, on the one hand, and the Agents,
on the other hand, shall be deemed to be in the same proportion that the total
proceeds of the sale of the Special Warrants received by the Company (net of
the Commission but before deducting expenses) bear to the Commission received
by the Agents.  In the case of liability arising out of any of the Documents,
the relative fault of the Company, on the one hand, and of the Agents, on the
other hand, shall be determined by reference, among other things, to whether
the untrue or alleged untrue statement or omission or other matter relates to
information supplied or which ought to have been supplied by the Company and
other applicable parties or the Agents and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement, omission or other matter.  The Company agrees that it would not be
just and equitable if contributions pursuant to this Agreement were determined
by pro rata allocation or by any other method of allocation which does not take
into account the equitable considerations referred to herein.  The rights to
contribution provided in this paragraph 10.3 shall be in addition to, and
without prejudice to, any other right to contribution which the Indemnified
Persons may have.

10.4     The Company will not make any claim for, and hereby irrevocably waives
any right by statute or common law to, contribution against the Agents or any
of the other Indemnified Persons with respect to any matter in respect of which
the Company has agreed to indemnify the Indemnified Persons hereunder.

10.5     The rights to indemnity and contribution herein provided shall be in
addition to and not in derogation of any other right to indemnity or
contribution which any Indemnified Person may have by statute or otherwise at
law.  It is the intention of the Company to constitute the Agents trustee for
its shareholders, directors, officers, employees and agents of the covenants of
the Company under paragraphs 10.1 to 10.4 hereof with respect to such persons
and the Agents agree to accept such trust and to hold and enforce such
covenants on behalf of such persons.

REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE AGENTS

         The Agents severally but not jointly acknowledge that the Special
Warrants and Underlying Shares have not been and will not be registered under
the U.S. Securities Act and may not be offered or sold to any person within the
United States except in accordance with Regulation S or pursuant to an exemption
from the registration requirements of the U.S. Securities Act. Accordingly, the
Agents severally but not jointly represent, warrant and covenant to the Company
that:

1.       The Agent has offered and sold, and will offer and sell Special
         Warrants only in accordance with Rule 903 of Regulation S or as
         provided in paragraphs 2 through 6 below. Accordingly, neither the
         Agent, its affiliates nor any persons acting on their behalf, has made
         or will make (except as permitted in paragraphs 2 through 9 below) (i)
         any offer to sell or any solicitation of an offer to buy, any Special
         Warrants to any person in the United States, (ii) any sale of Special
         Warrants to any purchaser unless, at the time the buy order was or will
         have been originated, the purchaser was outside the United States, or
         such Agent, affiliate or person acting on behalf of either reasonably
         believed that such purchaser was outside the United States, or (iii)
         any Directed Selling Efforts in the United States with respect to the
         Special Warrants or Underlying Shares.

2.       Each Agent, acting through its U.S. broker-dealer affiliate, may offer
         the Special Warrants in the United States to Accredited Investors with
         which such Agent has a preexisting relationship.

3.       Sales to each purchaser of the Special Warrants in the United States
         will have an aggregate purchase price of not less than US$250,000.

4.       No form of general solicitation or general advertising (as those terms
         are used in Regulation D) has been or will be used, including
         advertisements, articles, notices or other communications published in
         any newspaper, magazine, or similar media or broadcast over radio or
         television, or any seminar or meeting whose attendees had been invited
         by general solicitation or general advertising, in connection with the
         offer or sale of the Special Warrants in the United States.

5.       Prior to completion of any sale of Special Warrants in the United
         States, each U.S. purchaser thereof (a "U.S. Purchaser") will be
         required to represent, warrant and covenant to the Company to the
         effect that:

         (a)      Authorization and Effectiveness. The Purchaser is a valid and
                  subsisting corporation, has the necessary corporate capacity
                  and authority to execute and deliver this offer and to observe
                  and perform its covenants and obligations hereunder and has
                  taken all necessary corporate action in respect thereof, and,
                  upon acceptance by the Company, this offer will 




                                     - 28 -
<PAGE>   29

                  constitute a legal, valid and binding contract of the
                  Purchaser enforceable against the Purchaser in accordance with
                  its terms and neither the entering into of this Subscription
                  Agreement nor the completion of the transactions contemplated
                  hereby will result in a violation or breach of any law
                  applicable to the Purchaser or of any of the terms or
                  provisions of any constating documents of the Purchaser or of
                  any agreement to which the Purchaser is a party or by which it
                  is bound.

         (b)      Residence. The Purchaser is a resident of the jurisdiction
                  referred to under its address set forth on page 1 hereof,
                  which address is the residence or place of business of the
                  Purchaser and was not created nor is used solely for the
                  purpose of acquiring the Special Warrants.

         (c)      Purchasing as Principal. Except to the extent contemplated in
                  subparagraph (e), the Purchaser is purchasing the Purchaser's
                  Special Warrants (and the Underlying Shares in respect
                  thereof) as principal (as defined in applicable securities
                  legislation) for its own account, and not for the benefit of
                  any other person.

         (d)      Purchasing as Agents or Warrant Agent. In the case of the
                  purchase by the Purchaser of the Purchaser's Special Warrants
                  as agent or trustee for any principal whose identity is
                  disclosed or undisclosed or identified by account number only,
                  each beneficial purchaser of the Purchaser's Special Warrants
                  for whom the Purchaser is acting, is purchasing its
                  Purchaser's Special Warrants (and the Underlying Shares in
                  respect thereof) as principal for its own account, and not for
                  the benefit of any other person, for investment only and not
                  with a view to resale or distribution, and the Purchaser has
                  due and proper authority to act as agent or trustee for and on
                  behalf of such beneficial purchaser in connection with the
                  transactions contemplated hereby.

         (e)      Purchaser Has Benefit of Private Placement Exemption. The
                  Purchaser and, in the case of the purchase by the Purchaser of

         (f)      No Advertising. The offering and sale of the Purchaser's
                  Special Warrants to the Purchaser were not, so far as the
                  Purchaser is aware, made through an advertisement of the
                  Special Warrants in printed media of general and regular paid
                  circulation, radio or television or any other form of
                  advertisement or as part of a general solicitation and, except
                  for this Subscription Agreement, the only documents, if any,
                  delivered or otherwise furnished to the Purchaser in
                  connection with such offering and sale were the Offering
                  Memorandum, a term sheet relating to the Special Warrants,
                  annual or interim reports and other documents the contents of
                  which are prescribed by statute or regulation and generally
                  available research reports, memoranda and other materials
                  concerning the Company, Thornbury and Energy Fuels prepared by
                  others, which documents the Purchaser acknowledges do not,
                  individually or collectively, constitute an offering
                  memorandum or similar document (including an offering
                  memorandum as such term is defined in section 32(1) of the
                  Regulation to the Securities Act (Ontario)) and have not been
                  independently verified by the Agents. The Purchaser
                  acknowledges and agrees that the Company and the Agents take
                  no responsibility for the accuracy, adequacy or completeness
                  of the information contained in any such research reports,
                  memoranda or other materials concerning the Company, Thornbury
                  or Energy Fuels prepared by others.

         (g)      Offering Memorandum. The Purchaser has received and carefully
                  reviewed the Offering Memorandum and acknowledges that no
                  securities commission, agency, governmental authority,
                  regulatory body, stock exchange or other entity has reviewed
                  the Offering Memorandum or has made any finding or
                  determination as to the merits of an investment in, or made
                  any recommendation or endorsement with respect to, the Special
                  Warrants or the Underlying Shares.

         (h)      No Undisclosed Information. The Purchaser's Special Warrants
                  are not being purchased by the Purchaser as a result of any
                  material information concerning the Company that has not been
                  publicly disclosed and the Purchaser's decision to tender this
                  offer and acquire the Purchaser's Special Warrants has not
                  been made as a result of any oral or written representation as
                  to fact or otherwise made by or on behalf of the Company, the
                  Agents or any other person and is based entirely upon
                  currently available public information concerning the Company.

         (i)      Investment Intent. The Purchaser, or each beneficial purchaser
                  for whom it is purchasing, is acquiring Special Warrants to be
                  held for investment only and not with a view to resale,
                  distribution or other disposition of the Special Warrants or
                  the Underlying Shares in violation of the securities laws of
                  the United States.

         (j)      Investment Suitability. The Purchaser, and any beneficial
                  purchaser referred to in subparagraph (e) above, acknowledges
                  that the Special Warrants and the Underlying Shares are
                  speculative investments which involve a substantial degree of
                  risk and the Purchaser and each such beneficial purchaser has
                  such knowledge and experience in financial and business
                  affairs as to be capable of evaluating the merits and risks of
                  the investment hereunder in the Purchaser's Special Warrants
                  (and the Underlying Shares in respect thereof) and is able to
                  bear the economic risk of loss of such investment. No oral or
                  written representation has been made to the Purchaser by or on
                  behalf of the Company, the Agents or any other person (i) that
                  any person will resell or repurchase, or (except as provided
                  herein) refund all or any of the purchase price of, any of the
                  Purchaser's Special Warrants (or any of the Underlying Shares
                  in respect thereof), (ii) as to the future value or price of
                  the Special Warrants or the Underlying Shares or (iii) that
                  the Special Warrants or the Underlying Shares will be listed
                  and posted for trading, or that application has been or will
                  be made to list and post the Special Warrants or the
                  Underlying Shares for trading, on any stock exchange.

         (k)      No Registration in U.S. The Purchaser is aware that the
                  Special Warrants and the Underlying Shares have not been and
                  will not be registered under the U.S. Securities Act and the
                  sale contemplated hereby is being made in reliance on an
                  exemption from registration thereunder only to Accredited
                  Investors.

         (l)      Accredited Investor. The Purchaser is an Accredited Investor
                  and is acquiring the Special Warrants for its own account or
                  for the account of an Accredited Investor with respect to
                  which it exercises sole investment discretion, and not with a
                  view to any resale, distribution or other disposition of the
                  Special Warrants or Underlying Shares in violation of United
                  States federal and state securities laws.

         (m)      Adequate Information. The Purchaser has had access to all
                  information concerning the Company as it has considered
                  necessary in connection with its investment decision to
                  acquire the Special Warrants.

         (n)      Initial Trade Report. The Purchaser will, with respect to a
                  sale by the Purchaser of either Special Warrants or Underlying
                  Shares in British Columbia, file with the British Columbia
                  Securities Commission a report in the form required under the
                  British Columbia Securities Commission's Blanket Order #95/17
                  (the "Initial Trade Report") or the report required under the
                  laws of the jurisdiction in which the Company carries on
                  business or in which the Company is organized provided that

                  Initial Trade Report (the "Purchaser's Report") within ten
                  days of the initial trade of such Special Warrants or
                  Underlying Shares by the Purchaser, provided that where the
                  Purchaser has filed such report, the Purchaser is not required
                  to file a further report of additional trades of the Special
                  Warrants or Underlying Shares acquired on the same date and
                  under the same exemptions.

         (o)      Resales. The Purchaser understands that if it decides to
                  offer, sell or otherwise transfer such Special Warrants or the
                  Underlying Shares, or any of them, such securities may be

                       U.S. PRIVATE PLACEMENT CERTIFICATE


In connection with the private placement in the United States of the special
warrants (the "Special Warrants") of International Uranium Corporation (the
"Company") pursuant to the Agency Agreement dated as of March 14, 1997 among the
Company and the Agents named therein (the "Agency Agreement"), the undersigned,
on behalf of the several Agents and their respective U.S. affiliates, does
hereby certify as follows:

(i)      each U.S. affiliate of each U.S. Agent who offered or sold Special
         Warrants in the United States is a duly registered broker or dealer
         with the United States Securities and Exchange Commission (the "SEC")
         and the National Association of Securities Dealers, Inc. ("NASD") and
         is in good standing with the SEC and the NASD on the date hereof;

(ii)     each purchaser was provided with a copy of the Offering Memorandum
         dated March 19, 1997, for the offering of the Special Warrants in the
         United States;

(iii)    no form of general solicitation or general advertising (as those terms
         are used in Regulation D under the 1933 Act) was used by us, including
         advertisements, articles, notices or other communications published in
         any newspaper, magazine or similar media or broadcast over radio or
         television, or any seminar or meeting whose attendees had been invited
         by general solicitation or general advertising, in connection with the

         purchasing Special Warrants pursuant to Section 4(2) of the U.S.
         Securities Act is an Accredited Investor; and

(vi)     prior to any sale of Securities in the United States pursuant to

Warrants, entitling the holders 


<PAGE>   11

                                      -11-



thereof to subscribe for and be issued an aggregate of 40,000,000 Common Shares
(plus such additional indeterminate number of Common Shares as may be issued

provided in Article Eleven. Fractional Special Warrants will not be issued.

2.02              ISSUE PRICE. - The Special Warrants shall be issued for $1.25
per Special Warrant or such other price as may be established by action by the

Warrant Agent).

2.03              ENTITLEMENT OF WARRANTHOLDER. - Subject to Sections 4.01,
4.02 and 4.04, each Special Warrant authorized to be issued hereunder shall
entitle the holder thereof to subscribe for and be issued one Common Share
without further consideration to the Company. Special Warrants may be
exercisable by the holder, in whole only, at any time prior to the Expiry Time.

2.04              ADJUSTMENTS. - The number of Common Shares which may be issued
pursuant to the exercise or deemed exercise of the Special Warrants shall be
adjusted in the events and in the manner specified in Article Four.

conferred upon Warrantholders to exercise their Special Warrants for Common
Shares and provided that the provisions of Sections 4.01, 4.02 and 4.04 are
complied with, the Company shall issue that number of Common Shares from its
unissued share capital as are issuable pursuant to such exercise of Special
Warrants. At all times prior to such exercise, the Company shall have reserved
and allotted for issuance that number of Common Shares issuable upon exercise of
the Special Warrants.

2.06              WARRANTHOLDER NOT A SHAREHOLDER. - Except as otherwise
provided herein, nothing in this Indenture nor in the holding of a Special
Warrant, Warrant Certificate, or otherwise, shall be construed as conferring
upon a Warrantholder any right or interest whatsoever as a Shareholder or as a
holder of any other shares of the Company.

2.07              SPECIAL WARRANTS TO RANK PARI PASSU. - All Special Warrants
shall rank pari passu, regardless of the actual date of issue of the same.

2.08              SIGNING OF WARRANT CERTIFICATES. - The Warrant Certificates
shall be signed by any one Director or officer of the Company and may but need
not be under the Company's seal or a facsimile thereof (which shall be deemed to
be the Company's seal). The signature of such Director or officer may be
mechanically reproduced in facsimile and Warrant Certificates bearing such
facsimile signature shall be binding upon the Company as if they had been
manually signed by such officer or Director. Notwithstanding that any such
person whose manual or facsimile signature appears on 


<PAGE>   12

                                      -12-

any Warrant Certificate as such officer may no longer hold office at the date of
such Warrant Certificate or at the date of certification or delivery thereof,
any Warrant Certificate signed as aforesaid shall, subject to Section 2.09
hereof, be valid and binding upon the Company and the holder thereof shall be
entitled to the benefit of this Indenture. Warrant Certificates shall be dated
as of the date of the original issue of the Special Warrants evidenced thereby.

2.09              CERTIFICATION BY THE WARRANT AGENT. -

(1)      No Warrant Certificate shall be issued or, if issued, shall be valid
         for any purpose or entitle the holder to the benefit hereof until it
         has been countersigned and certified by manual signature by or on
         behalf of the Warrant Agent and such countersignature and certification
         by the Warrant Agent upon any Warrant Certificate shall be conclusive
         evidence as against the Company that the Warrant Certificate so
         countersigned and certified has been duly issued hereunder and that the
         holder is entitled to the benefit hereof.

(2)      The countersignature and certification of the Warrant Agent on Warrant
         Certificates issued hereunder shall not be construed as a
         representation or warranty by the Warrant Agent as to the validity of
         this Indenture or of a Warrant Certificate (except the due
         certification thereof) and the Warrant Agent shall in no respect be
         liable or answerable for the use made of the Warrant Certificates or
         any of them or of the consideration therefor, except as otherwise
         specified herein.

2.10              ISSUE IN SUBSTITUTION FOR LOST WARRANT CERTIFICATES. -

(1)      In case any Warrant Certificates issued and certified hereunder shall
         become mutilated, lost, destroyed or stolen, the Company, subject to
         applicable law, shall issue and thereupon the Warrant Agent shall
         certify and deliver a new certificate of like date and tenor as the one
         mutilated, lost, destroyed or stolen (i) in exchange for and in place
         of and upon cancellation of such mutilated certificate or (ii) in lieu
         of and in substitution for such lost, destroyed or stolen certificate
         and the substituted certificate shall be in a form approved by the
         Warrant Agent and shall be entitled to the benefit hereof and shall
         rank equally in accordance with its terms with all other Warrant
         Certificates issued or to be issued hereunder.

(2)      The applicant for the issue of a new certificate pursuant to Subsection
         2.10(1) shall bear the cost of the issue thereof and in case of loss,
         destruction or theft shall, as a condition precedent to the issue
         thereof, furnish to the Company and to the Warrant Agent such evidence
         of ownership and of the loss, destruction or theft, as the case may be,
         of the certificate so lost, destroyed or stolen as shall be
         satisfactory to the Company and to the Warrant Agent, acting
         reasonably, in their discretion and such applicant may also be required
         to furnish indemnity or 


<PAGE>   13

                                      -13-

         security in amount and form satisfactory to the Company and the Warrant
         Agent in their discretion to save each of them harmless, and shall pay
         the expenses, charges and any taxes applicable thereto of the Company
         and the Warrant Agent in connection therewith.

2.11              REPLACEMENT OF WARRANT CERTIFICATES. -

(1)      Warrant Certificates issued and certified hereunder, representing
         Special Warrants to subscribe for and purchase any specified number of
         Common Shares may, upon compliance with the reasonable requirements of
         the Warrant Agent, be replaced by Warrant Certificate(s) representing
         in the aggregate a like number of Special Warrants.

(2)      Warrant Certificates may be replaced at the stock transfer office of
         the Warrant Agent in the City of Toronto or any other place that is
         designated by the Company with the approval of the Warrant Agent. Any
         Warrant Certificate tendered for replacement shall be surrendered to
         the Warrant Agent and cancelled by the Warrant Agent, who will forward
         to the Company, a certificate evidencing such cancellation. The Company
         shall sign and the Warrant Agent shall countersign and certify all
         Warrant Certificates necessary to carry out replacements as aforesaid.

2.12              REPLACEMENT ADJUSTMENT. - Irrespective of any adjustments
pursuant to Article Four hereof, all replacement Warrant Certificates shall
continue to express the number of Special Warrant(s) evidenced thereby as if
such Warrant Certificates were initially issued as of the date of original issue
of the Special Warrants.

2.13              CHARGES FOR REPLACEMENT. - For each Warrant Certificate
replaced, the Warrant Agent, except as otherwise herein provided, shall, if
required by the Company, charge to the Warrantholder a reasonable sum for each
new Warrant Certificate issued. Payment for any and all taxes or governmental or
other charges required to be paid shall be made by the Warrantholder requesting
such replacement, as a condition precedent to the issuance thereof.

2.14              OWNERSHIP OF SPECIAL WARRANTS. - The Company and the Warrant
Agent shall deem and treat the registered holder of any Special Warrant as shown
on the Warrant Register or his legal representative or his attorney duly
appointed by an instrument in writing as the absolute holder and owner of such
Special Warrant for all purposes, and the Company and the Warrant Agent shall
not be affected by any notice or knowledge to the contrary. Except as otherwise
provided herein, the registered holder of a Warrant Certificate shall be
entitled to the rights evidenced by such Warrant Certificate free from all
rights of set-off or counterclaim between the Company and the original or any
intermediate holder thereof. All actions relating to any Warrantholder 


<PAGE>   14

                                      -14-



shall be valid and effectual to satisfy and discharge any liability hereunder
and under any Warrant Certificates.

2.15              TRANSFER OF SPECIAL WARRANTS. - The Special Warrants may only
be transferred upon compliance with the conditions herein on the Warrant
Register by a holder, his legal representative or his attorney duly appointed by
an instrument in writing in form and execution satisfactory to the Warrant Agent
and upon compliance with such reasonable requirements as the Warrant Agent may
prescribe and such transfer shall be duly noted on such Warrant Register by the
Warrant Agent. Notwithstanding anything to the contrary herein contained,
Special Warrants may only be transferred in accordance with applicable law. A
transferee shall not be entitled to the rights and privileges attached to the
Special Warrants unless the transfer is reflected in the Warrant Register.
Neither the Company nor the Warrant Agent shall be bound to inquire into the
title of any such registered holder.

2.16              U.S. LEGENDS. - The Warrant Agent understands and acknowledges
that the Special Warrants and the Common Shares issuable upon exercise of the
Special Warrants have not been and will not be registered under the U.S.
Securities Act. Each Warrant Certificate originally issued to a U.S. Person, and
each Warrant Certificate issued in exchange therefor or in substitution thereof,
shall bear the following legend unless such legend is to be removed pursuant to
the terms of this Indenture:

"THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED
STATES SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT") AND MAY BE
OFFERED, SOLD OR OTHERWISE TRANSFERRED ONLY (A) TO THE CORPORATION, (B) OUTSIDE
THE UNITED STATES IN ACCORDANCE WITH RULE 904 OF REGULATION S UNDER THE
SECURITIES ACT, OR (C) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE
SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER, IF APPLICABLE, AND IN COMPLIANCE
WITH ANY STATE SECURITIES LAWS OR (D) WITH THE PRIOR WRITTEN CONSENT OF THE
CORPORATION, PURSUANT TO ANOTHER EXEMPTION FROM REGISTRATION UNDER THE
SECURITIES ACT AND ANY APPLICABLE STATE SECURITIES LAWS."

Furthermore, all certificates representing Common Shares issued upon exercise of
the Special Warrants and all certificates issued in exchange therefor or in
substitution thereof or issued upon their exercise in accordance with Article
Four hereof, which are legended as above shall also bear the following
additional legend:

"DELIVERY OF THIS CERTIFICATE MAY NOT CONSTITUTE "GOOD DELIVERY" IN SETTLEMENT
OF TRANSACTIONS ON STOCK EXCHANGES IN CANADA. A NEW CERTIFICATE, BEARING NO
LEGEND, DELIVERY OF WHICH WILL CONSTITUTE "GOOD DELIVERY" MAY BE OBTAINED FROM
MONTREAL TRUST COMPANY OF CANADA UPON DELIVERY OF THIS CERTIFICATE AND A DULY
EXECUTED 


<PAGE>   15

                                      -15-


DECLARATION, IN A FORM SATISFACTORY TO MONTREAL TRUST COMPANY OF CANADA
AND THE CORPORATION, TO THE EFFECT THAT THE SALE OF THE SECURITIES REPRESENTED
HEREBY IS BEING MADE IN COMPLIANCE WITH RULE 904 OF REGULATION S UNDER THE
SECURITIES ACT."

provided that, if the Special Warrants or the Common Shares issued upon exercise
of the Special Warrants are being sold pursuant to Rule 904 of Regulation S
under the U.S. Securities Act, the legend may be removed if the holder provides
a declaration to the Warrant Agent or the Transfer Agent, as the case may be, to
the following effect (or as the Company may prescribe from time to time):

"The undersigned (a) acknowledges that the sale of the securities of
International Uranium Corporation (the "Company") to which this declaration
relates is being made in reliance on Rule 904 of Regulation S under the United
States Securities Act of 1933, as amended (the "1933 Act") and (b) certifies
that (1) the seller is not an affiliate of the Company (as defined in Rule 405
under the 1933 Act), (2) the offer of such securities was not made to a person
in the United States and either (A) at the time the buy order was originated,
the buyer was outside the United States, or the seller and any person acting on
its behalf reasonably believe that the buyer was outside the United States, or
(B) the transaction was executed on or through the facilities of The Toronto
Stock Exchange or any other designated offshore securities market, as defined in
Regulation S, and neither the seller nor any person acting on its behalf knows
that the transaction has been prearranged with a buyer in the United States, (3)
neither the seller nor any affiliate of the seller nor any person acting on its
or their behalf has engaged or will engage in any directed selling efforts in
the United States in connection with the offer and sale of such securities, (4)
the sale is bona fide and not for the purpose of "washing off" the resale
restrictions imposed because the securities are "restricted securities" (as such
term in defined in Rule 144(a)(3) under the 1933 Act), (5) the seller does not
intend to replace the securities sold in reliance on Rule 904 of the 1933 Act
with fungible unrestricted securities and (6) the contemplated sale is not a
transaction, or part of a series of transactions which, although in technical
compliance with Regulation S, is part of a plan or scheme to evade the
registration provisions of the 1933 Act. Terms used herein have the meanings
given to them by Regulation S."

and provided further, that, if any such securities are being sold pursuant to
Rule 144 under the U.S. Securities Act, the legend may be removed by delivery to
the Warrant Agent or the Transfer Agent, as the case may be, of an opinion of
counsel, of recognized standing reasonably satisfactory to the Company, that
such legend is no longer required under applicable requirements of the U.S.
Securities Act or state securities laws.

2.17              CERTAIN TRANSFERS. -

(i)      If the Warrant Certificate tendered for transfer bears the legend set
         forth in Section 2.16 hereof, and such legend is not to be removed in
         accordance with Section 2.16 hereof: (a) the Warrant Agent shall not
         issue or register a Warrant Certificate pursuant to such transfer in
         the name of or for the benefit of any resident of Canada; or (b) in the
         event that the transferee is a U.S. Person or is in the United States,
         the Warrant Certificate issued to such transferee shall bear the legend
         set forth in Section 2.16, and the requirement of such Section relating
         to legending the Common Shares issuable upon exercise of the Special
         Warrants shall also apply.

(ii)     If the Warrant Certificate tendered for transfer does not bear the
         legend set forth in Section 2.16, the Warrant Agent shall not register
         such transfer unless the transferor has certified on the Warrant
         Certificate that the transfer is being made, and the offer of the
         securities being transferred was made, to a person not in the United
         States. Notwithstanding the foregoing, the Warrant Agent shall not
         register the transfer if the Warrant Agent has reason to believe that
         the transferee is a person within the United States or is acquiring the
         Special Warrants evidenced thereby for the account or benefit of a
         person in the United States. Any Warrant Certificate issued to a
         transferee in a transfer contemplated by this Subsection 2.17(ii) shall
         not bear the legend set forth in Section 2.16.

2.18              RESIDENCY DETERMINATION - In determining who is a U.S. Person,
a person in the United States, or a resident of Canada, the Warrant Agent may
rely and shall be protected in relying upon the registered address of the holder
or the address of the transferee as indicated on the form of transfer for the
Special Warrants in question, as applicable, for all purposes.

2.19              ENTRY OF AGENT IN REGISTER - Notwithstanding the provisions of
this Article Two and Article Thirteen, any of the Agents shall be entitled to be
entered on the register as the holder of Special Warrants evidenced by a
particular Warrant Certificate upon delivery by such Agent to the Warrant Agent
of:

         (i)      the particular Warrant Certificate; and

         (ii)     a certificate of that Agent to the effect that the purchaser
                  of the Special Warrants evidenced by the particular Warrant
                  Certificate has declined or refused to accept delivery of, and
                  make payment for, the Special Warrants evidenced by the
                  particular Warrant Certificate in accordance with the
                  subscription or purchase agreement between such purchaser and
                  the Company.

                            NOTICE TO WARRANTHOLDERS

3.01              NOTICE. - Unless herein otherwise expressly provided, any
notice to be given hereunder to the Warrantholders shall be deemed to be validly
given if delivered personally or sent by registered letter postage prepaid
addressed to such Warrantholders at their post office addresses appearing in the
Warrant Register and shall be deemed to have been effectively given, received
and made on the date of personal delivery or on the fourth business day after
the time of mailing or upon actual receipt, whichever is sooner. Accidental
error or omission in giving notice or accidental failure to mail notice to any
Warrantholder or the inability of the Company to give or mail any notice due to
any matter beyond the reasonable control of the Company shall not invalidate any
action or proceeding taken in respect of matters pertaining to such notice
provided that in the case of disruption in postal services any notices, if
mailed, shall not be deemed to have been effectively given until it is
personally delivered. Any notice with respect to any Special Warrants, if
registered in the names of more than one holder, may be given to the holder
first named in the Warrant Register and any notice so given shall be sufficient
notice to all such registered holders having an interest in such Special
Warrants.


                                  ARTICLE FOUR
                          EXERCISE OF SPECIAL WARRANTS

4.01              METHOD OF EXERCISE OF SPECIAL WARRANTS. - Holders of Special
Warrants who wish to exercise their Special Warrants for Common Shares may do so
prior to the Expiry Time by delivering to the Warrant Agent at its principal
stock transfer office in Toronto, Ontario and at any other place or places that
may be designated by the Company with the approval of the Warrant Agent, the
Warrant Certificate with a duly completed and executed notice of exercise.

4.02              COMPLETION OF NOTICE OF EXERCISE FORM. -

(1)      Certificates representing the Common Shares for which Special Warrants
         are exercised, shall be delivered or mailed as described in Section
         4.03(2) to the Warrantholder, or as the Warrantholder may direct on the
         notice of exercise form, upon surrender of the corresponding Warrant
         Certificate(s) to the Warrant Agent. Certificates representing Common
         Shares issued pursuant to such exercise of Special Warrants shall be
         prepared in the name of the Warrantholder reflected in the Warrant
         Register. A Warrant Certificate with the duly completed and executed
         notice of exercise form shall be deemed to be surrendered only upon
         delivery thereof or, if sent by mail or other means of transmission,
         upon actual receipt thereof, in each case at the office of the Warrant
         Agent where 



<PAGE>   18

                                      -18-



         surrendered or such other place(s) provided for by the Company and 
         agreed to by the Warrant Agent.

(2)      A notice of exercise form shall be signed by the Warrantholder and

         entitled to acquire are subscribed for, (ii) the name of the holder,
         and (iii) the address of such person.

(3)      In connection with the replacement of Warrant Certificates and the
         exercise of Special Warrants and in compliance with such other terms
         and conditions hereof as may be required, the Company shall provide for
         one or more agencies in the City of Toronto, Ontario and any other
         place or places which may be designated by the Company (with the
         approval of the Warrant Agent, acting reasonably) at which Warrant
         Certificates may be surrendered for exercise for Common Shares.

(4)      The Warrant Agent shall record the particulars of the Special Warrants
         exercised for Common Shares which shall include the names and addresses
         of the persons who become holders of Common Shares upon such exercise
         and the Exercise Date. Within five business days of each Exercise Date,
         the Warrant Agent shall provide such particulars in writing to the
         Company and the Transfer Agent.

4.03              EFFECT OF EXERCISE OF SPECIAL WARRANTS. -

(1)      Upon compliance by the holder of any Warrant Certificate with the
         provisions of Section 4.01 and Section 4.02, and subject to the
         provisions of Subsection 4.04(2), the number of Common Shares
         subscribed for and thereby issuable shall be deemed to have been issued
         and the person or persons to whom such Common Shares are to be issued
         shall be deemed to have become the holder or holders of record of such
         Common Shares on the Exercise Date unless the transfer books of the
         Company shall be closed on such date, in which case the Common Shares
         subscribed for and thereby issuable shall be deemed to have been
         issued, and such person or persons shall be deemed to have become the
         holder or holders of record of such Common Shares, on the date on which
         such transfer books were reopened. Upon the exercise of Special
         Warrants, that portion of the Escrowed Funds relating to such Special
         Warrants shall be released to the Company in accordance with Article
         Twelve hereof.

(2)      The Company shall forthwith and in no event later than the third
         business day after the surrender of the Warrant Certificate (i) cause
         the Warrant Agent to mail to the person or persons in whose name or
         names the Common Shares so subscribed for and thereby issuable are to
         be issued, as specified in the notice of exercise completed on the
         Warrant Certificate, at the address specified in such notice of
         exercise or (ii) if so specified in such notice of exercise form, cause
         the Warrant Agent to deliver to such person or persons at the office of
         the Warrant 



<PAGE>   19

                                      -19-

         Agent where such Warrant Certificate was surrendered, a share
         certificate or certificates for the appropriate number of Common Shares
         to which the Warrantholder is entitled to be issued pursuant to the
         Warrant Certificate surrendered, provided that the Warrant Agent shall
         not be required to deliver certificates representing Common Shares
         issuable upon the exercise hereof when the Common Share transfer books
         of the Company are properly closed prior to any meeting of shareholders
         or for the payment of dividends or for any other purpose. In the event
         of the exercise of any Special Warrants in accordance with the
         provisions hereof during any such period delivery of certificates may
         be postponed for not exceeding five (5) business days after the date of
         the re-opening of said Common Shares transfer books.

4.04              SUBSCRIPTION FOR LESS THAN ENTITLEMENT. -

(1)      No holder may subscribe for and be issued less than the full number of
         Common Shares which are issuable pursuant to the Warrant Certificate.

(2)      Notwithstanding any adjustment provided for in Section 4.08 hereof or
         otherwise, the Company shall not be required, upon the exercise of a
         Special Warrant, to issue fractions of Common Shares or to distribute
         certificates which evidence fractional Common Shares. If the number of
         Common Shares to which a Warrantholder would otherwise be entitled upon
         the exercise of a Special Warrant is not a whole number then the number
         of Common Shares to be issued will be rounded down to the next whole
         number and the holder shall receive no consideration for any fraction
         of a Common Share.

4.05              WARRANT CERTIFICATES FOR FRACTIONS OF COMMON SHARES. - To the
extent that the holder of a Warrant Certificate is entitled to receive on the
exercise a fraction of a Common Share, such right may only be exercised in
respect of such fraction in combination with another Warrant Certificate which
in the aggregate entitles the Warrantholder to receive a whole number of Common
Shares.

4.06              EXPIRATION OF SPECIAL WARRANTS. -

(1)      In the event a holder does not exercise the Special Warrants by the
         Expiry Time and all of the Escrow Release Conditions are satisfied as
         evidenced by the delivery of the Escrow Certificate from the Company
         and the Agents to the Warrant Agent (which delivery shall be on a
         forthwith basis and in any event not later than the first business day
         thereafter), the Special Warrants held by such holder shall be
         exercised by the Warrant Agent on behalf of such holder at the Deemed
         Exercise Time without any further action on the part of the holder or
         the Company.

(2)      In the event that the Escrow Release Conditions are not satisfied by
         the Automatic Retraction Time, the Special Warrants held by a holder
         shall be retracted by the Warrant Agent on behalf of such holder
         without any further action on the part of the holder. At the time of
         such retraction, the Company shall purchase all of the Special Warrants
         registered in the holders' names at a price of $1.25 per Special
         Warrant plus such holder's pro rata share of the interest accrued on
         the Escrowed Funds, and the Warrant Agent shall pay to such holders
         from the Escrowed Funds an amount equal to $1.25 per Special Warrant so
         purchased together with the pro rata share of the interest accrued on
         the Escrowed Funds, calculated from the date hereof to and including
         the day immediately preceding the date of payment to such holders. Such
         payment shall be made by way of cheque payable in the City of Toronto,
         and upon delivery of such cheque the Special Warrants shall be void and
         of no value. The foregoing is subject to the obligations of the Company
         to pay to the Warrant Agent any additional amounts as may be necessary
         in accordance with Section 12.03 hereof.

(3)      The Warrant Agent shall have no obligation to review and approve the
         documents attached to the Escrow Certificate, and shall be entitled to
         release the Escrowed Funds upon the receipt of the Escrow Certificate
         as provided for in this Indenture. Following the delivery of the Escrow
         Certificate to the Warrant Agent, the Warrant Agent shall send a notice
         to holders of Special Warrants in accordance with Section 3.01 advising
         of the exercise of Special Warrants and providing instructions on how
         such holders may obtain certificates representing Common Shares.

4.07              CANCELLATION OF SURRENDERED WARRANT CERTIFICATES. - All
Warrant Certificates surrendered to the Warrant Agent shall be cancelled by the
Warrant Agent who shall furnish the Company with a certificate identifying the
Warrant Certificates so cancelled and the number of Common Shares subscribed for
pursuant to each Warrant Certificate.

4.08              ADJUSTMENTS IN CERTAIN CIRCUMSTANCES. - Subject to Section
                  4.09:

         (a)      if at any time prior to the Expiry Time, the Company shall (i)
                  consolidate the outstanding Common Shares into a lesser number
                  of Common Shares or (ii) subdivide the outstanding Common
                  Shares into a greater number of Common Shares, as the case may
                  be, the holder, if the Special Warrants have not been
                  exercised prior to the effective date of such consolidation or
                  subdivision, as the case may be, upon the exercise of such
                  Special Warrant thereafter, shall be entitled to receive and
                  shall accept, the number of Common Shares of the Company that
                  the holder would have been entitled to receive on such
                  consolidation or subdivision if, on the record date or the
                  effective date thereof, as the case may be, it had been

<PAGE>   21

                                      -21-


                  the registered holder of the number of Common Shares to which
                  it is by its Warrant Certificate, prima facie, entitled. Such
                  adjustment shall be made successively whenever any event
                  referred to in this subsection (a) shall occur;

         (b)      if at any time prior to the Expiry Time, there is a
                  reclassification or redesignation of the Common Shares into
                  other shares or a reorganization of the Company (other than as
                  described in (a) hereof), or an amalgamation, merger or
                  arrangement of the Company with or into any other body
                  corporate or other entity (other than an amalgamation, merger
                  or arrangement, which does not result in a reclassification of
                  the outstanding Common Shares or a change of the Common Shares
                  into other shares) or a sale or conveyance of the property and
                  assets of the Company as an entirety or substantially as an
                  entirety to any other body corporate or other entity, the
                  holder, if the Special Warrants have not been exercised prior
                  to the effective date of such reclassification, redesignation,
                  change, reorganization, amalgamation, merger, arrangement,
                  sale or conveyance, upon the exercise of such Special Warrant
                  thereafter, shall be entitled to receive and shall accept the
                  number of Common Shares or other securities or property of the
                  Company or of the body corporate, or other entity, resulting
                  from such amalgamation, merger or arrangement or to which such
                  sale or conveyance may be made, as the case may be, that the
                  holder would have been entitled to receive on such
                  reclassification, redesignation, change, reorganization,
                  amalgamation, merger, arrangement, sale or conveyance if, on
                  the record date or the effective date thereof, as the case may
                  be, it had been the registered holder of the number of Common
                  Shares to which it is by its Warrant Certificate, prima facie,
                  entitled;

                  In the case of the amalgamation, merger or arrangement with or
                  sale or conveyance of the property and assets of the Company
                  as an entirety or substantially as an entirety to another body
                  corporate or other entity (the "Successor"), the Successor
                  shall expressly assume, by written agreement executed and
                  delivered to the holder, the due and punctual performance and
                  observance of each and every covenant and condition of this
                  Indenture and the Warrant Certificate to be performed and
                  observed by the Company;

         (c)      if at any time prior to the Expiry Time, the Company shall pay
                  any stock dividend or stock dividends upon the Common Shares,
                  the holder, if the Special Warrants have not been exercised
                  prior to the record date for payment of such stock dividend or
                  dividends, upon the exercise of such Special Warrants
                  thereafter, shall be entitled to receive in addition to the
                  number of Common Shares such additional number of securities
                  of the 



<PAGE>   22

                                      -22-


                  appropriate class that the holder would have been entitled to
                  receive if on the record date for payment of such stock
                  dividend or dividends it had been the registered holder of the
                  number of Common Shares to which it is by its Warrant
                  Certificate, prima facie, entitled;

         (d)      the adjustments provided for herein are cumulative. After any
                  adjustment pursuant hereto, the term "Common Shares" where
                  used in this Indenture shall be interpreted to mean Common
                  Shares of any class or classes which, as a result of all prior
                  adjustments pursuant hereto, the holder is entitled to receive
                  upon the exercise of its Special Warrants;

         (e)      in the event of any question arising with respect to
                  adjustments provided for herein, such question shall be
                  conclusively determined by the Company's auditors or, if they
                  are unable or unwilling to act, by such other firm of
                  independent chartered accountants as may be selected by the
                  board of directors of the Company, who shall have access to
                  all necessary records of the Company, the holder and all other
                  persons in interest, and such determination shall be binding
                  upon the Company, the Warrant Agent and the holder;

         (f)      notwithstanding anything in this Indenture to the contrary, no
                  adjustment shall be made in the number of Common Shares to be
                  acquired upon the exercise of the Special Warrants unless it
                  would result in a change of at least one one-hundredth of a
                  Common Share (but in each such case any adjustment that would
                  otherwise have been required then to be made shall be carried
                  forward and taken into account in any subsequent adjustment).
                  In case the Common Shares shall be subdivided into a greater
                  number or consolidated into a lesser number, the minimum
                  adjustment aforesaid shall thereupon be itself adjusted to
                  such amount which bears the same relation to the minimum
                  adjustment established immediately prior to such event as the
                  total number of Common Shares outstanding immediately prior
                  thereto bears to the total number of Common Shares outstanding
                  immediately thereafter. Any such minimum adjustment so
                  established shall continue in effect until the same shall
                  again be changed as herein provided;

         (g)      as a condition precedent to the taking of any action which
                  would require any adjustment pursuant hereto, the Company
                  shall take any corporate action which may, in the opinion of
                  counsel of the Company, be necessary in order that the Company
                  has unissued and allotted in its authorized capital and may
                  validly and legally issue as fully paid and non-assessable all
                  the securities which the holder is entitled to receive on the
                  full exercise of its Special Warrants in accordance with the
                  provisions hereof; and

                                      -23-

         (h)      the Company shall from time to time immediately after the
                  occurrence of any event which requires an adjustment or
                  readjustment as provided herein, deliver a certificate of the
                  Company to the Company's auditors or, if they are unable or
                  unwilling to act, to such other firm of independent chartered
                  accountants as may be selected by the board of directors of
                  the Company, specifying the nature of the event requiring the
                  same and the amount of the adjustment necessitated thereby and
                  setting forth in reasonable detail the method of calculation
                  and the facts upon which such calculation is based, which
                  certificate and the amount of the adjustment specified therein
                  shall be verified by an opinion of the Company's auditors, or
                  the chartered accountants selected by the board, as the case
                  may be, and, when so verified, shall be conclusive and binding
                  on all parties in interest. When so verified, the Company
                  shall forthwith give notice to the holders in the manner
                  provided herein specifying the events requiring such
                  adjustment or readjustment and the result thereof.

4.09              POSTPONEMENT. - Any additional shares, rights, options or
warrants issuable or cash amounts payable to a Warrantholder pursuant to Section
4.08 shall be held in trust by the Warrant Agent pending the exercise of the
Special Warrants for Common Shares and shall not be released to the
Warrantholder until such exercise occurs.

4.10              NOTICE OF ADJUSTMENT. -

(1)      At least ten (10) days prior to the effective date or record date, as
         the case may be, of any event which requires or might require an
         adjustment in any of the subscription rights to any of the Warrant
         Certificates and the number of Common Shares which are issuable upon
         the exchange thereof, the Company shall:

         (a)      file with the Warrant Agent a certificate of the Company
                  specifying the particulars of such event and, if determinable,

                  adjustment; and

         (b)      give notice to the Warrantholders in the manner provided for

(2)      In case any adjustment for which a notice pursuant to Subsection
         4.10(1) has been given is not then determinable, the Company shall
         promptly after such adjustment is determinable;

         (a)      file with the Warrant Agent a computation of such adjustment;
                  and

                  in Article Three of the adjustment.

         shall be entitled to rely absolutely on any adjustment calculations of
         the Company or the Company's auditors.

         exercise of the Special Warrants held by such person during the period
         of ten days after the giving of a notice required by this Section 6.01

         Indenture.

(10)     It shall not, prior to the earlier of the date on which all Special
         Warrants have been exercised and the Expiry Time, amend or approve an
         amendment of the articles of the Company in any manner which would
         adversely affect the rights of the Warrantholders or any other
         instrument relating to the issue of the Special Warrants without the
         consent of the holders of a simple majority of the Special Warrants
         outstanding.

execution of its duties hereunder (including the reasonable compensation and the
disbursements of its counsel and all other advisors and assistants not regularly

signing such Warrantholders' Request against the costs, charges, expenses and
liabilities which may be incurred by the Warrant Agent in connection with the
calling and holding of such meeting, convene a meeting of the Warrantholders. In
the event of the Warrant Agent failing within ten (10) days after receipt of
such written request by the Company or Warrantholders' Request and indemnity
given as aforesaid to give notice to convene a meeting, the Company or such
Warrantholders, as the case may be, may convene such meeting. Every such meeting
shall be held at such place as may reasonably be approved or determined by the
Warrant Agent.

8.02              NOTICE. - At least fifteen (15) days' notice of any meeting of
Warrantholders shall be given to the Warrantholders in the manner provided in
Article Three and a copy thereof shall be sent by post to the Warrant Agent
unless the meeting has been called by it and to the Company unless the meeting
has been called by it. Such notice shall state the time when and the place where
the meeting is to be held and shall state briefly the general nature of the
business to be transacted thereat. It shall not be necessary for any such notice
to set out the terms of any resolution to be proposed or any of the provisions
of this Article Eight. The notice convening any such meeting may be signed by an
appropriate officer of the Warrant Agent or of the Company or the person or
persons designated by such Warrantholders, as the case may be.

8.03              CHAIRMAN. - An individual (who need not be a Warrantholder)
nominated in writing by the Warrant Agent shall be chairman of the meeting and
if no individual is so nominated, or if the individual so nominated is not
present within fifteen (15) minutes from the time fixed for the holding of the
meeting, or if such person is unable or unwilling to act as chairman, the
Warrantholders present in person or by proxy shall choose some individual to be
chairman.

8.04              QUORUM. - Subject to the provisions of Section 8.12, at any
meeting of the Warrantholders a quorum shall consist of Warrantholders present

Warrants outstanding as of the date of the meeting, provided that at least two
persons entitled to vote thereat are 


<PAGE>   28

                                      -28-


personally present. If a quorum of the Warrantholders shall not be present
within thirty (30) minutes from the time fixed for holding any meeting, the
meeting, if summoned by the Warrantholders or on a Warrantholders' Request,
shall be dissolved; but in any other case the meeting shall be adjourned to the
same day in the next following week (unless such day is a non-business day in
which case it shall be adjourned to the next following business day thereafter)
at the same time and place. At the reconvened meeting the Warrantholders present
in person or by proxy shall form a quorum and may transact the business for
which the meeting was originally called notwithstanding that they may not hold
at least ten per cent (10%) of all the then outstanding Special Warrants.

8.05              POWER TO ADJOURN. - Subject to the provisions of Section 8.04,
the chairman of any meeting at which a quorum of the Warrantholders is present
may, with the consent of the meeting, adjourn any such meeting and no notice of
such adjournment need be given except such notice, if any, as the meeting may
prescribe.

8.06              SHOW OF HANDS. - Every question submitted to a meeting shall
be decided in the first place by a majority of the votes given on a show of
hands except that votes on extraordinary resolutions shall be given in the
manner hereinafter provided. At any such meeting, unless a poll is duly demanded
as herein provided, a declaration by the chairman that a resolution has been
carried or carried unanimously or by a particular majority or lost or not
carried by a particular majority shall be conclusive evidence of the fact. Any
Warrantholder present in person or by proxy can demand a poll at any meeting in
accordance with the provisions of Section 8.07.

8.07              POLL. - On every extraordinary resolution, or on any other
question submitted to a meeting and after a vote by show of hands in respect of
such question, if requested by the chairman or by one of or more of the
Warrantholders acting in person or by proxy and holding at least five per cent
(5%) of all the Special Warrants then outstanding, a poll shall be taken in such
manner as the chairman shall direct. Questions other than extraordinary
resolutions shall be decided by a majority of the votes cast on the poll.

8.08              VOTING. - On a show of hands every person who is present and
entitled to vote, whether as a Warrantholder or as a proxy for one or more
absent Warrantholders or both, shall have one vote. On a poll, each
Warrantholder present in person or represented by a proxy duly appointed by
instrument in writing shall be entitled to one vote in respect of each Special
Warrant then held by him. A proxy need not be a Warrantholder. The chairman of
any meeting shall be entitled both on a show of hands and on a poll, to vote in
respect of the Special Warrants, if any, held or represented by him.

approval of the Warrant Agent may from time to time make regulations and from
time to time vary such regulations as it shall from time to time think fit:

         (a)      for the deposit of instruments appointing proxies at such
                  place and time as the Warrant Agent, the Company or the
                  Warrantholder calling the meeting, as the case may be, may
                  direct in the notice calling the meeting;

         (b)      for the deposit of instruments appointing proxies at some
                  approved place or places other than the place at which the
                  meeting is to be held and enabling particulars of such
                  instruments appointing proxies to be mailed, cabled,
                  telecopied or telegraphed before the meeting to the Company or
                  to the Warrant Agent at the place where the same is to be held
                  and for the voting of proxies so deposited as though the
                  instruments themselves were produced at the meeting;

         (c)      for the form of the instrument of proxy; and

         (d)      generally, for the calling of meetings of Warrantholders and
                  for the conduct of business thereat.

Any regulations so made shall be binding and effective and the votes given in
accordance therewith shall be valid and shall be counted. Save as such
regulations may provide, the only persons who shall be recognized at any meeting
as the holders of any Warrant Certificates, or as entitled to vote or, subject
to Section 8.10, be present at the meeting in respect thereof, shall be the
registered holders of the Special Warrants, and their legal advisers may attend
such meeting, but shall have no vote as such.

8.10              COMPANY AND WARRANT AGENT MAY BE REPRESENTED. - The Company
and the Warrant Agent, by their respective officers or directors, and the legal
advisers of the Company and the Warrant Agent may attend any meeting of the
Warrantholders, but shall have no vote as such.

8.11              POWERS EXERCISABLE BY EXTRAORDINARY RESOLUTION. - In addition
to all other powers conferred upon them by any other provisions of this
Indenture or by law, the Warrantholders at a meeting shall have the following

                  Warrantholders or the Warrant Agent (in its capacity as
                  trustee hereunder or on behalf of the Warrantholders) with the
                  Company, whether such rights arise under this Indenture or the

         (b)      power to direct or authorize the Warrant Agent (i) to enforce
                  any of the covenants of the Company contained in this
                  Indenture or the Warrant Certificates, (ii) to enforce any of
                  the rights of the Warrantholders in any manner specified in
                  such extraordinary resolution or (iii) to refrain from
                  enforcing any such covenant or right;

         (c)      power to waive and direct the Warrant Agent to waive any

                  such extraordinary resolution;

         (d)      power to restrain any Warrantholder from taking or instituting
                  any suit, action or proceeding against the Company (i) for the
                  enforcement of any of the covenants of the Company contained
                  in this Indenture or the Warrant Certificates or (ii) to
                  enforce any of the rights of the Warrantholders;

         (e)      power to direct any Warrantholder who, as such, has brought

                  charges and expenses reasonably and properly incurred by such
                  Warrantholder in connection therewith;

         (f)      power to appoint any persons (whether Warrantholders or not)

         (g)      power to remove the Warrant Agent and to appoint a new trustee

8.12              EXTRAORDINARY RESOLUTION. -

(1)      The expression "extraordinary resolution" when used in this Indenture
         means, subject as hereinafter in this Section 8.12 and in Sections 8.15
         and 8.16 provided, a resolution proposed at a meeting of Warrantholders
         duly called for that purpose and held in accordance with the provisions
         of this Article Eight at which there are present in person or by proxy
         Warrantholders holding at least fifty-one per cent (51%) of all the
         Special Warrants outstanding as of the date of the meeting and passed
         by the affirmative votes of Warrantholders holding not less than
         sixty-six and two-thirds per cent (66-2/3%) of all the Special Warrants

<PAGE>   31

                                      -31-

(2)      If, at any such meeting called for the purpose of passing an
         extraordinary resolution, Warrantholders holding fifty-one per cent
         (51%) of all the then outstanding Special Warrants are not present in
         person or by proxy within thirty (30) minutes from the time fixed for
         holding the meeting, then the meeting, if called by Warrantholders or
         on a Warrantholders' Request, shall be dissolved; but in any other case
         it shall stand adjourned to such day, being not less than fifteen (15)
         or more than sixty (60) days later, and to such place and time as may
         be determined by the chairman. Not less than ten days' notice shall be
         given of the time and place of such adjourned meeting in the manner
         provided in Article Three. Such notice shall state that at the
         adjourned meeting the Warrantholders present in person or by proxy
         shall form a quorum but it shall not be necessary to set forth the
         purposes for which the meeting was originally called or any other
         particulars. At the adjourned meeting the Warrantholders present in
         person or by proxy shall form a quorum notwithstanding the provisions
         of Subsection 8.12(1) and may transact the business for which the
         meeting was originally called and a resolution proposed at such
         adjourned meeting and passed by the requisite vote as provided in
         Subsection 8.12(1) shall be an extraordinary resolution within the
         meaning of this Indenture, notwithstanding that Warrantholders holding
         fifty-one per cent (51%) of all the then outstanding Special Warrants
         are not present in person or by proxy at such adjourned meeting.

(3)      Votes on an extraordinary resolution shall always be given on a poll
         and no demand for a poll on an extraordinary resolution shall be
         necessary.

8.13              POWERS CUMULATIVE. - It is hereby declared and agreed that any
one or more of the powers in this Indenture, stated to be exercisable by the
Warrantholders by extraordinary resolution or otherwise, may be exercised from
time to time and the exercise of any one or more of such powers from time to
time shall not be deemed to exhaust the right of the Warrantholders to exercise
such power or powers then or thereafter from time to time.

8.14              MINUTES. - Minutes of all resolutions and proceedings at every
meeting of Warrantholders shall be made and duly entered in books to be from
time to time provided for that purpose by the Warrant Agent at the expense of
the Company, and any such minutes, if signed by the chairman of the meeting at
which such resolutions were passed or proceedings had, or by the chairman of the
next succeeding meeting of the Warrantholders, shall be prima facie evidence of
the matters therein stated and, until the contrary is proved, every such
meeting, in respect of the proceedings of which minutes shall have been made,
shall be deemed to have been duly called and held, and all resolutions passed
thereat or proceedings taken, to have been passed and taken.

8.15              INSTRUMENTS IN WRITING. - All actions which may be taken and
all powers that may be exercised by the Warrantholders at a meeting held as
provided in this Article Eight may also be taken and exercised by Warrantholders
holding sixty-six and two thirds per cent (66-2/3%) of all the then outstanding
Special Warrants, by an instrument in writing signed in one or more counterparts
by such Warrantholders in person or by attorney duly appointed in writing and
the expression "extraordinary resolution" when used in this Indenture shall
include an instrument so signed.

8.16              BINDING EFFECT OF RESOLUTIONS. - Every resolution and every
extraordinary resolution passed in accordance with the provisions of this
Article Eight at a meeting of Warrantholders shall be binding upon all the
Warrantholders, whether present or absent at such meeting, and every instrument
in writing signed by Warrantholders in accordance with the provisions of Section
8.15 shall be binding upon all the Warrantholders, whether signatories thereto
or not, and each and every Warrantholder and the Warrant Agent (subject to the
provisions for indemnity herein contained) shall be bound to give effect
accordingly to every such resolution, extraordinary resolution and instrument in
writing.

8.17              HOLDINGS BY COMPANY AND WARRANT AGENT DISREGARDED. - In
determining whether Warrantholders are present at a meeting of Warrantholders
for the purpose of determining a quorum or have concurred in any consent,
resolution, extraordinary resolution, Warrantholders' Request, waiver, or other
action under this Indenture, Warrant Certificates owned by the Company and any
subsidiary of the Company shall be deemed not to be outstanding and shall be
disregarded. The Company shall from time to time and forthwith upon the Warrant
Agent's written request file with the Warrant Agent a certificate of the Company
setting forth as at the date of such certificate the number of Special Warrants
owned by the Company and any subsidiary of the Company.

                             SUPPLEMENTAL INDENTURES

9.01              PROVISION FOR SUPPLEMENTAL INDENTURES FOR CERTAIN PURPOSES. -
From time to time the Company (when authorized by action by the Directors) and
the Warrant Agent may, subject to the provisions of this Indenture and they
shall, when so directed by the provisions of this Indenture, execute and deliver
by their proper officers, indentures or instruments supplemental hereto, which
thereafter shall form part hereof, for any one or more or all of the following
purposes:

         (a)      setting forth adjustments pursuant to the provisions of
                  Section 4.08 and in the pro rata apportionments subject
                  however to the rights of Warrantholders not being impaired or
                  prejudiced thereby otherwise than as provided herein;


<PAGE>   33

                                      -33-



         (b)      adding to the provisions hereof such additional covenants and
                  enforcement provisions as, in the opinion of counsel, are
                  necessary or advisable in the premises, provided that the same
                  are not, in the opinion of the Warrant Agent, prejudicial to
                  the interests of the Warrantholders;

         (c)      giving effect to any extraordinary resolution passed as
                  provided in Article Eight;

         (d)      making such provisions not inconsistent with this Indenture as
                  may be necessary or desirable with respect to matters or
                  questions arising hereunder or for the purpose of obtaining a
                  listing or quotation of the Special Warrants on any stock
                  exchange, provided that such provisions are not, in the
                  opinion of the Warrant Agent, prejudicial to the interests of
                  the Warrantholders;

         (e)      adding to or altering the provisions hereof in respect of the
                  registration and transfer of Special Warrants, making
                  provision for the exchange of Warrant Certificates, or making
                  any modification in the form of the Warrant Certificates which
                  does not affect the substance thereof;

         (f)      modifying any of the provisions of this Indenture or relieving
                  the Company from any of the obligations, conditions or
                  restrictions herein contained, provided that no such
                  modification or relief shall be or become operative or
                  effective in such manner as to impair any of the rights of the
                  Warrantholders or of the Warrant Agent and provided further
                  that the Warrant Agent may in its sole discretion decline to
                  enter into any such supplemental indenture which in its
                  opinion may not afford adequate protection to the Warrant
                  Agent when the same shall become operative; and

         (g)      for any other purpose not inconsistent with the terms of this
                  Indenture, including the correction or rectification of any
                  ambiguities, defective provisions, errors or omissions herein,
                  provided that, in the opinion of the Warrant Agent, the rights
                  of the Warrant Agent and of the Warrantholders are in no way
                  prejudiced thereby.

9.02              SUCCESSOR COMPANY. - In the case of a consolidation, 
amalgamation, merger or transfer of the undertaking or assets of the Company as
an entirety or substantially as an entirety to another corporation (the
"Successor Company"), the Successor Company resulting from such consolidation,
amalgamation, merger or transfer (if not the Company) shall expressly assume, by
supplemental indenture satisfactory in form to the Warrant Agent and executed
and delivered to the Warrant Agent, the due and punctual performance and
observance of each and every covenant 



<PAGE>   34

                                      -34-



and obligation contained in this Indenture to be performed by the Company, as
the case may be.


                                   ARTICLE TEN
                          CONCERNING THE WARRANT AGENT

10.01    TRUST INDENTURE LEGISLATION. -

(1)      If and to the extent that any provision of this Indenture limits,
         qualifies or conflicts with a mandatory requirement of Applicable
         Legislation, such mandatory requirement shall prevail.

(2)      The Company and the Warrant Agent agree that each will at all times in
         relation to this Indenture and any action to be taken hereunder observe
         and comply with and be entitled to the benefits of Applicable
         Legislation.

10.02    RIGHTS AND DUTIES OF WARRANT AGENT. -

(1)      In the exercise of the rights and duties prescribed or conferred by the
         terms of this Indenture, the Warrant Agent shall exercise that degree
         of care, diligence and skill that a reasonably prudent trustee would
         exercise in comparable circumstances. No provision of this Indenture
         shall be construed to relieve the Warrant Agent from liability for its
         own negligent action, its own negligent failure to act, or its own
         willful misconduct or bad faith.

(2)      Subject to Subsection 10.02(1), the Warrant Agent shall not be bound to
         do or take any act or action for the enforcement of any of the
         obligations of the Company under this Indenture unless and until it
         will have received a Warrantholder's Request defining the action which
         the Warrant Agent is required to take and then the obligation of the
         Warrant Agent to commence or continue any act, action or proceeding for
         the purpose of enforcing any rights of the Warrant Agent or the
         Warrantholders hereunder shall be conditional upon the Warrantholders
         furnishing, when required by notice by the Warrant Agent, sufficient
         funds to commence or continue such act, action or proceeding and
         indemnity reasonably satisfactory to the Warrant Agent to protect and
         hold harmless the Warrant Agent against the costs, charges, expenses
         and liabilities to be incurred thereby and any loss or damage it may
         suffer by reason thereof. None of the provisions contained in this
         Indenture shall require the Warrant Agent to expend or risk its own
         funds or otherwise incur financial liability in the performance of any
         of its duties or in the exercise of any of its rights or powers unless
         indemnified as aforesaid.



<PAGE>   35

                                      -35-


(3)      The Warrant Agent may, before commencing or at any time during the
         continuance of any such act, action or proceeding, require the
         Warrantholders, at whose instance it is acting, to deposit with the
         Warrant Agent the Warrant Certificates held by them, for which Warrant
         Certificates the Warrant Agent shall issue receipts.

(4)      Every provision of this Indenture that by its terms relieves the
         Warrant Agent of liability or entitles it to rely upon any evidence
         submitted to it is subject to the provisions of Applicable Legislation
         and of this Section 10.02.

10.03    EVIDENCE. -

(1)      Whenever it is provided in this Indenture that the Company shall
         deposit with the Warrant Agent resolutions, certificates, reports,
         opinions, requests, orders or other documents, it is intended that the
         truth, accuracy and good faith on the effective date thereof of the
         facts and opinions stated in all documents so deposited shall, in each
         and every such case, be conditions precedent to the right of the
         Company to have the Warrant Agent take the action to be based thereon.
         The Warrant Agent may rely and shall be protected in acting upon any
         such documents deposited with it in purported compliance with any such
         provision or for any other purpose hereof, but may, in its discretion,
         require further evidence before acting or relying thereon.

(2)      The Warrant Agent may rely and shall be protected in acting upon any
         resolution, certificate, statement, instrument, opinion, report,

(2)      The Warrant Agent may act and shall be protected in acting in good
         faith on the opinion or advice of or information obtained from any

                  Section 10.08 and in the certificate of the Warrant Agent on
                  the Warrant Certificates) or required to verify the same, but
                  all such statements or recitals are and shall be deemed to be
                  made by the Company;

         (b)      the Warrant Agent shall not be bound to give notice to any
                  person or persons of the execution hereof;

                  responsibility whatever or be in any way responsible for the
                  consequence of any breach on the part of the Company of any of
                  the representations, warranties or covenants herein contained

                  renewal thereof) of this Indenture or any instrument ancillary
                  or supplemental hereto;

         (e)      the Warrant Agent will at all times be indemnified and saved
                  harmless by the Company from and against all claims, demands,
                  losses, actions, causes of action, costs, charges, expenses,
                  damages and liabilities whatsoever arising in connection with
                  this Warrant Indenture, including, without limitation, those
                  arising out of or related to actions taken or omitted to be
                  taken by the Warrant Agent contemplated hereby, legal fees and
                  disbursements on a solicitor and client basis and costs and
                  expenses incurred in connection with the enforcement of this
                  indemnity, which the Warrant Agent may suffer or incur,
                  whether at law or in equity, in any way caused by or arising,
                  directly or indirectly, in respect of any act, deed, matter or
                  thing whatsoever made, done, acquiesced in or omitted in or
                  about or in relation to the execution of its duties as Warrant
                  Agent. The foregoing provisions of this Section 10.06 do not
                  apply to the extent that in any circumstances there has been a
                  failure by the Warrant Agent or its employees or agents to act
                  honestly and in good faith or to discharge the Warrant Agent's
                  obligations under Section 10.01. This indemnity and any
                  limitations thereto as set forth herein, will survive the
                  termination or discharge of this Warrant Indenture and the
                  resignation of the Warrant Agent;

         (f)      the Warrant Agent shall not be bound to give any notice or do
                  or take any act, action or proceeding by virtue of the powers
                  conferred on it hereby unless and until it shall have been
                  required so to do under the terms hereof; nor shall the
                  Warrant Agent be required to take notice of any default
                  hereunder, unless and until notified in writing of such
                  default, which notice shall distinctly specify the default
                  desired to be brought to the attention of the Warrant Agent,
                  and in the absence of any such notice the Warrant Agent may
                  for all purposes of this Indenture conclusively assume that no
                  default has been made in the observance or performance of any
                  of the representations, warranties, covenants, agreements or
                  conditions contained herein. Any such notice shall in no way
                  limit any discretion herein given to the Warrant Agent to
                  determine whether or not the Warrant Agent shall take action
                  with respect to any default;

         (g)      the Warrant Agent shall incur no liability with respect to the
                  delivery or non-delivery of any certificates whether delivered
                  by hand, mail or any other means; and

         (h)      the Warrant Agent shall have no obligation to ensure
                  compliance with any laws applicable to the issue, transfer or
                  exercise of any Special Warrants or Common Shares.

         10.07(1), by giving to the Company not less than sixty (60) days' prior
         notice in writing or such shorter prior notice as the Company may
         accept as sufficient. The Warrantholders, by extraordinary resolution,
         shall have power at any time to remove the Warrant Agent and to appoint
         a new trustee. In the event of the Warrant Agent resigning or being
         removed as aforesaid or being dissolved, becoming bankrupt, going into
         liquidation or otherwise becoming incapable of acting hereunder, the
         Company shall forthwith appoint a new trustee unless such extraordinary
         resolution has appointed a new trustee; failing such appointment by the
         Company, the retiring Warrant Agent or any Warrantholder may apply to a
         justice of the Ontario Court of Justice (General Division), on such
         notice as such justice may direct for the appointment of a new trustee;
         but any new trustee so appointed by the Company or by the Court shall
         be subject to removal as aforesaid by the Warrantholders. Any new
         trustee appointed under any provision of this Subsection 10.07(1) shall
         be a corporation authorized to carry on the business of a trust company
         in the Province of Ontario and British Columbia and, if required by the
         Applicable Legislation of any other province in Canada, in such other
         provinces. On any such appointment the new trustee shall be vested with
         the same powers, rights, duties and responsibilities as if it had been
         originally named herein as trustee without any further assurance,
         conveyance, act or deed; but there shall be immediately executed, at
         the expense of the Company, all such conveyances or other instruments
         as may, in the opinion of counsel, be necessary or advisable for the
         purpose of assuring the same to the new trustee, provided that,
         following any resignation or removal of the Warrant Agent and
         appointment of a successor trustee, the successor trustee shall have
         executed an appropriate instrument accepting such appointment and, at
         the request of the Company, the predecessor Warrant Agent shall execute
         and deliver to the successor trustee an appropriate instrument
         transferring to such successor trustee all rights and powers of the
         Warrant Agent hereunder so ceasing to act.

(2)      Upon the appointment of a successor trustee, the Company shall promptly
         notify the Warrantholders thereof in the manner provided for in Article
         Three hereof.

(3)      Any corporation into or with which the Warrant Agent may be merged or
         consolidated or amalgamated, or any corporation resulting therefrom to
         which the Warrant Agent shall be a party, or any corporation succeeding
         to the trust business of the Warrant Agent shall be the successor to
         the Warrant Agent hereunder without any further act on its part or any
         of the parties hereto, provided that, such corporation would be
         eligible for appointment as a successor trustee under Subsection
         10.07(1) above.

(1)      The Warrant Agent represents to the Company that at the time of
         execution and delivery hereof no material conflict of interest exists
         in the Warrant Agent's role as a fiduciary hereunder and agrees that in
         the event of a material conflict of interest arising hereafter it will,
         within ninety (90) days after ascertaining that it has such material
         conflict of interest, either eliminate the same or assign its trust
         hereunder to a successor trustee approved by the Company and meeting
         the requirements set forth in Subsection 10.07(1).

(2)      Subject to Subsection 10.08(1), the Warrant Agent or a successor
         trustee, in its personal or any other capacity, may buy, lend upon and
         deal in securities of the Company and generally may contract and enter

         Company without being liable to account for any profit made thereby.

(S.C. 1991, c. 46, as amended) or deposited for safekeeping with any such bank.
Unless herein otherwise expressly provided, any moneys so held pending the
application or withdrawal thereof under any provisions of this Indenture, may be

interest (if any) then current on similar deposits or, with the consent of the
Company, may be deposited in the deposit department of the Warrant Agent or any
other loan or trust company or chartered bank authorized to accept deposits
under the laws of Canada or a province thereof. All interest or other income
received by the Warrant Agent in respect of such deposits and investments shall,
subject to the provisions of Article Twelve hereof, belong to the Company.

                    Special Warrants to Acquire Common Shares

         THIS CERTIFIES THAT, for value received,______________________________
(the "Holder") is the registered holder of_______________________ Special
Warrants and is entitled, upon the terms and conditions set out herein, to
acquire for no additional consideration, one (1) common share (a "Common Share")
in the capital of International Uranium Corporation (the "Company") for each
such Special Warrant held, subject to adjustment.

Special Warrants shall be exercisable for Common Shares by the Holder at any
time prior to the Expiry Time by surrendering this certificate to Montreal Trust
Company of Canada (the "Warrant Agent") at 151 Front Street West, Stock and Bond
Transfer Department, 8th Floor, Toronto, Ontario, M5J 2N1, Attention:
Reorganization Department, together with a duly completed and executed notice of
exercise in the form attached hereto (the "Notice of Exercise"). At any time
prior to the Expiry Time the Special Warrants represented by this certificate
shall be exercisable by the Holder, in whole only, and the Company shall cause
the Warrant Agent, upon receipt by the Warrant Agent of an executed Notice of
Exercise to issue certificates representing the Common Shares issuable upon the
exercise of the Special Warrants represented hereby to be mailed to the Holder
as recorded on the register maintained by the 



<PAGE>   42

                                      -42-


Warrant Agent and the Special Warrants represented by this certificate shall,
upon such delivery, be void and of no value or effect. The Holder shall be
deemed to have become the holder of record of such Common Shares immediately
prior to the close of business on the date of receipt by the Warrant Agent of
the Notice of Exercise.

All Special Warrants and Common Shares acquired upon the exercise of the Special
Warrants are subject to restrictions on resale until:

         (a)      the appropriate "hold period" has expired;

         (b)      a further statutory exemption may be relied upon by the
                  Holder;

         (c)      the securities sought to be resold are qualified for
                  distribution under a prospectus; or

         (d)      an appropriate discretionary order is obtained pursuant to
                  applicable securities legislation.

If the Escrow Release Conditions have not been satisfied by the Automatic
Retraction Time, the Warrant Agent shall automatically repurchase the
unexercised Special Warrants at such time on behalf of the Company, and the
holder of such unexercised Special Warrants shall be entitled to receive for
each Special Warrant an amount equal to $1.25 per Special Warrant so purchased
together with the Holder's pro rata share of the interest on the Escrowed Funds
(as defined in the Special Warrant Indenture dated the date hereof (the "Warrant
Indenture")). Such payment shall be made by way of cheque payable in the City of
Toronto, and upon delivery of such cheque the Special Warrants shall be void and
of no value.

Notwithstanding any adjustments provided for herein or otherwise, the Company
shall not be required upon the exercise of any Special Warrants, to issue
fractional Common Shares in satisfaction of its obligations hereunder. To the
extent that the Holder would otherwise be entitled to acquire a fraction of a
Common Share, such right may be exercised in respect of such fraction only in
combination with other rights which in the aggregate entitle the Holder to
acquire a whole number of Common Shares.

Nothing in this certificate or in the holding of a Special Warrant evidenced
hereby shall be construed as conferring upon the Holder any right or interest
whatsoever as a shareholder of the Company or entitle the Holder to any right or
interest in respect of any Common Shares, except as herein expressly provided.

All Special Warrants shall rank pari passu, notwithstanding the actual date of
the issue thereof.

                                      -43-



The Warrant Agent on behalf of the Company shall cause a register to be kept in
which shall be entered the names and addresses of all holders of the Special
Warrants and the number of Special Warrants held by them. No transfer of Special
Warrants shall be valid unless made by the Holder or its executors,
administrators or other legal representatives or its attorney duly appointed by
an instrument in writing in form and execution satisfactory to the Company and
the Warrant Agent on the register to be kept at the offices of the Warrant Agent
in the City of Toronto upon compliance with such reasonable requirements as the
Company and Warrant Agent may prescribe, including compliance with all
applicable securities legislation and the conditions prescribed in the Warrant
Indenture between the Warrant Agent and the Company, and recorded on the
register of holders of Special Warrants maintained by the Warrant Agent, nor
until stamp or governmental or other charges arising by reason of such transfer
have been paid. The transferee of a Special Warrant shall, after a form of
transfer acceptable to the Company and Warrant Agent is duly completed and the
Special Warrant is lodged with the Warrant Agent and upon compliance with all
other reasonable requirements of the Company and the Warrant Agent or law, be
entitled to have its name entered on the register as the owner of such Special
Warrant, free from all equities or rights of set-off or counterclaim between the
Company and the transferor or any previous holder of such Special Warrant, save
in respect of equities of which the Company is required to take notice by
statute or by order of a court of competent jurisdiction. The Company and the
Warrant Agent may treat the registered holder of any Special Warrant certificate
as the absolute owner of the Special Warrants represented thereby for all
purposes, and the Company and the Warrant Agent shall not be affected by any
notice or knowledge to the contrary except where the Company and Warrant Agent
is required to take notice by statute or by order of a court of competent
jurisdiction.

The number of Common Shares to be issued upon exercise of the right of exercise
evidenced hereby shall be subject to adjustment from time to time in the events
and in the manner specified in the Warrant Indenture. The Holder is advised to
carefully review such indenture for the particulars thereof.

The Warrant Agent shall not be required to deliver certificates representing
Common Shares issuable upon the exercise hereof when the Common Share transfer
books of the Company are properly closed, prior to any meeting of shareholders
or for the payment of dividends or for any other purpose and in the event of the
exercise of any Special Warrant in accordance with the provisions hereof during
any such period delivery of certificates may be postponed for not exceeding five
(5) business days after the date of the re-opening of said Common Shares
transfer books, provided however that any such postponement of delivery of
certificates shall be without prejudice to the right of the Holder to receive
such certificates after the Common Share transfer books shall have been
reopened.

Subject as herein provided, all or any of the rights conferred upon the Holder
may be enforced by the Holder by appropriate legal proceedings. No recourse
under or upon 


<PAGE>   44

                                      -44-


any obligation, covenant or agreement herein contained shall be had against any
shareholder, officer or director of the Company, either directly or through the
Company, it being expressly agreed and declared that the obligations under the
Special Warrants represented by this certificate are solely corporate
obligations of the Company and that no personal liability whatever shall attach
to or be incurred by the shareholders, officers, or directors of the Company or
any of them in respect thereof, any and all rights and claims against every such
shareholder, officer or director being hereby expressly waived as a condition of
and as a consideration for the issue of the Special Warrants represented by this
certificate.

If this Special Warrant certificate is stolen, lost, mutilated or destroyed the
Company may, on such terms as it may in its discretion impose, respectively
issue and countersign a new Special Warrant certificate of like denomination,
tenor and date as the certificate so stolen, lost, mutilated or destroyed.

This certificate and the Special Warrants represented hereby shall be governed
by, performed, construed and enforced in accordance with the Warrant Indenture
and the laws of the Province of Ontario and the laws of Canada applicable
therein.

Time shall be of the essence hereof.

         IN WITNESS WHEREOF the Company has caused this Special Warrant
certificate to be signed by the signature of its duly authorized officer as of

                               ESCROW ARRANGEMENTS

12.01    NET PROCEEDS AND INVESTMENT THEREOF. - The Warrant Agent acknowledges
receipt of the net proceeds of the offering of Special Warrants (after deducting
the Agents' Commission) and agrees to hold the same in trust on behalf of the
persons who have an interest therein pursuant hereto, and to disburse and deal
with the same as part of the Escrowed Funds all on the terms hereof. Pending
disbursement of the Escrowed Funds, the Warrant Agent agrees to hold, invest and
reinvest the same in Government of Canada Treasury Bills or as otherwise
directed by the Company from time to time. All such investments shall be
retained by the Warrant Agent in safekeeping at its principal office in Toronto
and shall be held in trust by the Warrant Agent on behalf of the persons who
have an interest therein pursuant hereto.

12.02    DISBURSEMENT OF ESCROWED FUNDS. - Subject to Section 12.04, the Warrant
Agent shall realize on the investments referred to in Section 12.01 and disburse
all or part of the Escrowed Funds in the following circumstances:

         (a)      if a holder exercises Special Warrants prior to the Expiry
                  Time, the Warrant Agent shall disburse to the Company from the
                  Escrowed Funds an amount equal to the subscription price of
                  the Special Warrants so exercised, net of any applicable
                  Agents' Commission, together with the interest accrued
                  thereon;

         (b)      if the Deemed Exercise Time has occurred and the Warrant Agent
                  has received the Escrow Certificate issued by the Company and
                  the Agents, the Warrant Agent shall as soon as practicable
                  thereafter disburse the Escrowed Funds (including, for greater
                  certainty, the interest accrued thereon) to the Company or as
                  the Company may direct; and

         (c)      if the Automatic Retraction Time has occurred and the Warrant
                  Agent has not received the Escrow Certificate, the Warrant
                  Agent shall disburse the Subscription Funds, together with the
                  pro rata share of the interest accrued on the Escrowed Funds,
                  all in accordance with Subsection 4.06(2).

12.03    ADDITIONAL PAYMENTS BY COMPANY. - In the event that the Warrant Agent
determines that the Escrowed Funds will not be sufficient to allow the Warrant
Agent to pay any amount or amounts pursuant to Section 4.06 or this Article
Twelve, the Warrant Agent shall give written notice of such determination to the
Company and the Company shall within one business day of the date upon which
such notice is given, pay to the Warrant Agent such amount as will be sufficient
to allow the Warrant Agent to pay any amount or amounts payable in accordance
with Section 4.06 or this Article Twelve. For greater certainty and without
limiting the generality of the foregoing, the Company shall

contribute to the Escrowed Funds any amounts required to cover any currency
exchange risks and all transaction costs, in the event that the Escrow Release
Conditions (including without limitation the closing of the Acquisition on the
terms contemplated herein) is not completed as contemplated and the Escrowed
Funds are returned to the Warrant Agent for disbursement to the holders in
accordance with their respective retraction rights provided for in Subsection
4.06(2). 

12.04 DELIVERY TO THIRD PARTY ESCROW AGENT. - Notwithstanding any other
provision hereof, the Warrant Agent shall, upon receipt of a joint direction
from the Company and the Agents, realize on all or part of the investments
referred to in Section 12.01 and deliver all or part of the Escrowed Funds to a
third party escrow agent pursuant to and in accordance with the instructions set
forth in such direction for the purpose of facilitating the completion of the
closing of the Acquisition.

reason of the bankruptcy of any Security Holder, in which cases the Escrow Agent
shall hold the said certificates subject to this agreement, for whatever person,
firm or corporation shall be legally entitled to be or become the registered
owner thereof. It is understood that the Exchange consents to the release from
escrow of one-fifth of the Regulatory Shares on an automatic basis on each of
the first, second, third, fourth and fifth anniversary dates (or if not a
business day, the next business day following that date) of the listing date.
The Regulatory Shares shall be released from escrow to each of the Security
Holders pro rata to the number of Regulatory Shares placed in escrow by such
Security Holder, and the Escrow Agent shall notify the Exchange upon the
completion of each such release.

3.                The Escrow Agent shall deliver, by courier delivery, the
certificates evidencing the Regulatory Shares to the Security Holder at the
address for such Security Holder appearing on the register for the common shares
of the Issuer unless such Security Holder otherwise directs the Escrow Agent in
writing not less than ten (10) days prior to any release from escrow.

4.                The Security Holders hereby direct the Escrow Agent to retain
their respective securities and the certificates (including any replacement
securities or certificates) representing the same and not to do or cause
anything to be done to release the same from escrow or to allow any transfer,
hypothecation or alienation thereof except with and as directed by the written
consent, order or direction of the Exchange or in accordance with paragraph 2
hereof. The Escrow Agent hereby accepts the responsibilities placed on it hereby
and agrees to perform the same in accordance with the terms hereof and the
written consents, orders or directions of the Exchange.

5.                If during the period in which any of the said securities are
retained in escrow pursuant hereto, any dividend is received by the Escrow Agent
in respect of the escrowed securities, any such dividend shall be forthwith paid
or transferred to the respective Security Holders entitled thereto.

6.                All voting rights attached to the Regulatory Shares shall at
all times be exercised by the respective registered owners thereof.

7.                The parties hereby agree that the Exchange may, in certain
circumstances, including but not limited to the suspension from trading or
delisting of the Issuer by the Exchange, require that all or any of the
Regulatory Shares then in escrow be tendered to the Issuer by way of gift or for
cancellation. Any such Regulatory Shares shall remain in escrow subject to the
terms and conditions of this agreement until the securities are fully and
effectually cancelled or otherwise transferred for the benefit of the Issuer.
Where the Regulatory Shares cannot be cancelled, they shall be held for the
benefit of the Issuer by the Escrow Agent and remain in escrow subject to the
terms and conditions of this agreement but they shall not be voted and any
dividends shall be donated back for the benefit of the Issuer.

8.       (i)      The Escrow Agent shall not have any duties or responsibilities
                  except those set forth in this agreement and shall not incur
                  any liability in acting on any signature, notice, request,
                  waiver, consent, receipt or other paper or documents believed
                  by the Escrow Agent to be genuine.

         (ii)     The Escrow Agent may act or refrain from acting in respect of
                  any matter referred to in this agreement in full reliance on
                  and by and with the advice of counsel or other professional
                  advisors which may be selected by it, and shall be fully
                  protected in so acting or refraining from acting on the advice
                  of counsel or advisors. The reasonable costs of such counsel
                  and of the Escrow Agent shall be paid by the Issuer.

         (iii)    The Escrow Agent shall be required to release the Regulatory
                  Shares only as specified in paragraph 2 hereunder, and no
                  further authorization or independent verification shall be
                  necessary.

         (iv)     The Security Holders and the Issuer hereby jointly and
                  severally agree to and do hereby release and indemnify and
                  save harmless the Escrow Agent from and against all claims,
                  suits, demands, costs, damages and expenses which may be
                  occasioned by reason of the Escrow Agent's compliance in good
                  faith with the terms hereof.

         (v)      In the event of any disagreement arising regarding the terms
                  of the agreement, the Escrow Agent shall be entitled, at its
                  option, to refuse to comply with any and all demands
                  whatsoever until the dispute is settled

                                      -4-


                  either by agreement amongst the parties or by a court of
                  competent jurisdiction.

         (vi)     The Escrow Agent shall not be required to defend any legal
                  proceedings which may be instituted against it in respect of
                  or arising out of anything herein contained unless requested
                  to do so in writing by a party hereto and indemnified and
                  funded to its reasonable satisfaction against the cost and
                  expense of such defence, provided that such legal proceeding
                  does not arise as a result of an allegation of fraud or
                  negligence on the part of the Escrow Agent or its employees.

9.                The Issuer hereby acknowledges the terms and conditions of
this agreement and agrees to take all reasonable steps to facilitate its
performance, including the payment of all reasonable fees and expenses of the
Escrow Agent in relation hereto.

10.               If the Escrow Agent should wish to resign, it shall give at
least sixty (60) days' notice to the Issuer, which may, with the written consent
of the Exchange, by writing appoint another Escrow Agent in its place and such
appointment shall be binding on the Security Holders and the new Escrow Agent
shall assume and be bound by the obligations of the Escrow Agent hereunder.

11.               The written consent, order or direction of the Exchange as to
a release from escrow of all or part of the said securities shall terminate this
agreement only in respect to those securities so released. For greater
certainty, this clause does not apply to securities transferred within escrow.

12.               If the Issuer is delisted by the Exchange, thereafter any
consent, order or direction of the Exchange herein required in relation to the
Regulatory Shares will, instead, require the consent, order or direction of the
Ontario Securities Commission and the Ontario Securities Commission may require
that escrowed Regulatory Shares be tendered to the Issuer by way of gift or for
cancellation pursuant to paragraph 7 hereof.

13.               The Escrow Agent may employ or retain such counsel as it may
reasonably require for the purpose of discharging its duties hereunder, and the
reasonable fees and disbursements of such counsel shall be for the account of
the Issuer.

14.               Any notice or other document to be given to any of the parties
hereto or herein referred to pursuant to or arising out of this agreement may be
given by mailing the same by prepaid registered mail or by personal or facsimile
delivery, at the following address:

    provided, however, that if the number of Shares taken up under the Option
    during any such 12 month period is less than 33 1/3% of the Shares covered
    by the Option, the Optionee shall have the right, at any time or from time
    to time during the remainder of the term of the Option, to purchase such
    number of Shares subject to the Option which were purchasable, but not
    purchased by him, during such 12 month period; and

(c) to the extent that the Option Price of Shares (determined on the date of
    grant) with respect to which Incentive Stock Options are exercisable for the
    first time during any calendar year (under the Plan and all other stock
    option plans of the Corporation) exceeds US$100,000, such portion in excess
    of US$100,000 shall be treated as a Nonqualified Stock Option.

5.5 The Option Price of Shares which are the subject of any Option shall in no
circumstances be lower than the Market Price of the Shares at the date of the
grant of the Option.

5.6 The maximum number of Shares which may be reserved for issuance to any one
Optionee under this Plan or under any other Share Compensation Arrangement shall
not exceed 5% of the Shares outstanding at the date of the grant (on a
non-diluted basis).

5.7 The maximum number of Shares which may be reserved for issuance to Insiders
under the Plan or under any other Share Compensation Arrangement shall be 10% of
the Shares outstanding at the date of the grant (on a non-diluted basis).

5.8 The maximum number of Shares which may be issued to any one Insider and such
Insider's associates under the Plan and any other Share Compensation Arrangement
in any 12 month period shall be 5% of the Shares outstanding at the date of the
issuance (on a non-diluted basis). The maximum number of Shares which may be
issued to all Insiders under the Plan and any other Share Compensation
Arrangement in any 12 month period shall be 10% of the Shares outstanding at the
date of the issuance (on a non-diluted basis).

5.9 Any entitlement to acquire Shares granted pursuant to the Plan or any other
Share Compensation Arrangement prior to the Optionee becoming an Insider shall
be excluded for the purposes of the limits set out in 5.7 and 5.8 above.

5.10 An Option is personal to the Optionee and is non-assignable.

5.11 All references in the Plan to "the Shares outstanding at the date of the
issuance" shall mean that number of Shares determined on the basis of the number
of Shares that are outstanding immediately prior to the share issuance in
question, excluding Shares issued pursuant to any Share Compensation Arrangement
over the preceding one year period.

                               EXERCISE OF OPTIONS

6.1 Subject to the provisions of the Plan, an Option may be exercised from time
to time by delivery to the Corporation at its registered office of a written
notice of exercise addressed to the Secretary of the 







<PAGE>   5

                                      -5-



Corporation specifying the number of Shares with respect to which the Option is
being exercised and accompanied by payment in full of the Option Price of the
Shares to be purchased. Certificates for such Shares shall be issued and
delivered to the Optionee within a reasonable period of time following the
receipt of such notice and payment.

6.2 The exercise price for Shares purchased under an Option shall be paid in
full to the Corporation by delivery of consideration in an amount equal to the
Option Price. Such consideration must be paid in cash or by cheque or, unless
the Board in its sole discretion determines otherwise, either at the time the
Option is granted or at any time before it is exercised, a combination of cash
and/or cheque (if any). The Corporation may permit an Optionee to elect to pay
the Option Price by authorizing a third party to sell Shares (or a sufficient
portion of such Shares) acquired upon exercise of the Option and remit to the
Corporation a sufficient portion of the sale proceeds to pay the entire Option
Price and any tax withholding resulting from such exercise. In addition, the
Option Price for Shares purchased under an Option may be paid, either singly or
in combination with one or more of the alternative forms of payment authorized
by this Section 6.2, by such other consideration as the Board may permit.
Notwithstanding the foregoing, if the Board decides to grant stock appreciation
rights, such rights shall be subject to the applicable approvals provided for in
Section 9.1.

6.3 Notwithstanding any of the provisions contained in the Plan or in any
Option, the Corporation's obligation to issue Shares to an Optionee pursuant to
the exercise of an Option shall be subject to:

(a) completion of such registration or other qualification of such Shares or
    obtaining approval of such governmental or regulatory authority as counsel
    to the Corporation shall reasonably determine to be necessary or advisable
    in connection with the authorization, issuance or sale thereof;

(b) the listing of such Shares on the Exchange, if applicable; and

(c) the receipt from the Optionee of such representations, agreements and
    undertakings, including as to future dealings in such Shares, as the
    Corporation or its counsel reasonably determines to be necessary or
    advisable in order to safeguard against the violation of the securities laws
    of any jurisdiction.

In this connection the Corporation shall, to the extent necessary, take all
reasonable steps to obtain such approvals, registrations and qualifications as
may be necessary for the issuance of such Shares in compliance with applicable
securities laws and for the listing of such Shares on the Exchange.


                                    ARTICLE 7
                        TERMINATION OF EMPLOYMENT; DEATH

7.1 Subject to Section 7.2 and any express resolution passed by the Board with
respect to an Option, an Option, and all rights to purchase pursuant thereto,
shall expire and terminate 30 days following the date upon which the Optionee
ceases to be a director, officer or a part-time or full-time employee of the
Corporation or of any Subsidiary. The entitlement of a Consultant to Options
including the termination thereof shall be in accordance with the terms of the
consulting agreement entered into between the Corporation or the Subsidiary and
the Consultant, provided that in no event shall the Options of any Consultant
continue to be outstanding 12 months following the date upon which the
consulting agreement between the Consultant and the Corporation or the
Subsidiary is terminated.

7.2 If, before the expiry of an Option in accordance with the terms thereof, the
employment of the Optionee with the Corporation or with any Subsidiary shall
terminate, in either case by reason of the death of the Optionee, such Option
may, subject to the terms thereof and any other terms of the Plan, be exercised
by the legal representative(s) of the estate of the Optionee at any time during
the first year 







<PAGE>   6


                                      -6-


following the death of the Optionee (but prior to the expiry of the Option in
accordance with the terms thereof) but only to the extent that the Optionee was
entitled to exercise such Option at the date of the termination of the
Optionee's employment.

7.3 Options shall not be affected by any change of employment of the Optionee or
by the Optionee ceasing to be a director where the Optionee continues to be
employed by the Corporation or any Subsidiary or continues to be a director or
officer of, the Corporation or any Subsidiary.


                                    ARTICLE 8
                    CHANGE IN CONTROL AND CERTAIN ADJUSTMENTS

8.1 Notwithstanding any other provision of this Plan in the event that the
Corporation receives an offer (the "Offer") for:

(a) the acquisition by any Person of Shares or rights or options to acquire
    Shares of the Corporation or securities which are convertible into Shares of
    the Corporation or any combination thereof such that after the completion of
    such acquisition such Person would be entitled to exercise 30% or more of
    the votes entitled to be cast at a meeting of the shareholders; or

(b) the sale by the Corporation of all or substantially all of the property or
    assets of the Corporation;

then notwithstanding that at the effective time of the Offer the Optionee may
not be entitled to all the Shares granted by the Option, the Optionee shall be
entitled to exercise the Options to the full amount of the Shares remaining at
that time from the date of the Offer to the date of the close of any such
transaction. If such transaction is not completed within 90 days of the date of
the Offer and the Optionee has not so exercised that portion of the Option
relating to Shares to which the Optionee would not otherwise be entitled, this
provision shall cease to apply to the Offer.

8.2 Appropriate adjustments with respect to Options granted or to be granted, in
the number of Shares optioned and in the Option Price, shall be made by the
Board to give effect to adjustments in the number of Shares of the Corporation
resulting from subdivisions, consolidations or reclassifications of the Shares
of the Corporation, the payment of stock dividends or cash dividends by the
Corporation (other than dividends in the ordinary course), the distribution of
securities, property or assets by way of dividend or otherwise (other than
dividends in the ordinary course), or other relevant changes in the capital
stock of the Corporation or the amalgamation or merger of the Corporation with
or into any other entity, subsequent to the approval of the Plan by the Board.
The appropriate adjustment in any particular circumstance shall be conclusively
determined by the Board in its sole discretion, subject to approval by the
Shareholders of the Corporation and to acceptance by the Exchange respectively,
if applicable.


                                    ARTICLE 9
                       AMENDMENT OR DISCONTINUANCE OF PLAN

9.1 The Board may amend or discontinue the Plan at any time upon receipt of
requisite shareholder approval, to the extent required by any applicable laws or
regulations (including without limitation, Section 422 of the Code), or
requisite regulatory approval (including without limitation, the approval of the
Exchange), if applicable, provided, however, that no such amendment may (i)
increase the maximum number of Shares that may be optioned under the Plan or
change the manner of determining the minimum Option Price without the requisite
approval (if applicable) or (ii) alter or impair any of the terms of any Option
previously granted to an Optionee under the Plan without the consent of the
Optionee. Any amendments to the terms of an Option shall also require applicable
regulatory approval, including without limitation, the approval of the Exchange.












<PAGE>   7


                                      -7-


9.2 Any change or adjustment to an outstanding Incentive Stock Option shall not,
without the consent of the Optionee, be made in a manner so as to constitute a
"modification" that would cause such Incentive Stock Option to fail to continue
to qualify as an Incentive Stock Option.

9.3 The Plan will have no fixed expiration date; provided, however, that no
Incentive Stock Options may be granted more than 10 years after the earlier of
the Plan's adoption by the Board and approval by the shareholders of the
Corporation.


                                   ARTICLE 10
                            MISCELLANEOUS PROVISIONS

10.1 The holder of an Option shall not have any rights as a shareholder of the
Corporation with respect to any of the Shares covered by such Option until such
holder shall have exercised such Option in accordance with the terms of the Plan
(including tendering payment in full of the Option Price of the Shares in
respect of which the Option is being exercised) and the issuance of Shares by
the Corporation.

10.2 Nothing in the Plan or any Option shall confer upon an Optionee any right
to continue in the employ of the Corporation or any Subsidiary or affect in any
way the right of the Corporation or any Subsidiary to terminate the Optionee's
employment at any time; nor shall anything in the Plan or any Option be deemed
or construed to constitute an agreement, or an expression of intent, on the part
of the Corporation or any Subsidiary to extend the employment of any Optionee
beyond the time which the Optionee would normally be retired pursuant to the
provisions of any present or future retirement plan of the Corporation or any
Subsidiary, or beyond the time at which the Optionee would otherwise be retired
pursuant to the provisions of any contract of employment with the Corporation or
any Subsidiary.

10.3 To the extent required by law or regulatory policy or necessary to allow
Shares issued on exercise of an Option to be free of resale restrictions, the
Corporation shall report the grant, exercise or termination of the Option to the
Exchange and the appropriate securities regulatory authorities.

10.4 The Corporation may require the Optionee to pay to the Corporation the
amount of any withholding taxes that the Corporation is required to withhold
with respect to the grant or exercise of any Option. Subject to the Plan and
applicable law, the Board may, in its sole discretion, permit the Optionee to
satisfy withholding obligations in whole or in part, by paying cash or by
electing to have the Corporation withhold Shares in such amounts as are
equivalent to the Market Price in order to satisfy the withholding obligation.
The Corporation shall have the right to withhold from any Shares issuable
pursuant to an Option or from any cash amounts otherwise due or to become due
from the Corporation to the Optionee an amount equal to such taxes, and such
withheld Shares shall be cancelled if required by any applicable law or
regulatory authority. The Corporation may also deduct from any Option any other
amounts due from the Optionee to the Corporation. For the purposes of this
Section 10.4, all references to the Corporation shall be deemed to include
references to a Subsidiary where the context permits.

                                   ARTICLE 11
                       SHAREHOLDER AND REGULATORY APPROVAL

11.1 The Plan shall be subject to the approval of the shareholders of the
Corporation to be given by a resolution passed at a meeting of the shareholders
of the Corporation in accordance with the Business Corporations Act, Ontario,
and to acceptance by the Exchange, if applicable. Any Options granted prior to
such approval and acceptance shall be conditional upon such approval and
acceptance being given, and no such Options may be exercised unless such
approval and acceptance is given.

Optionee pursuant to the exercise of the Option shall be subject to:

           (a)    completion of such registration or other qualification of such
                  Optioned Shares or obtaining approval of such governmental or
                  regulatory authority as counsel to the Company shall
                  reasonably determine to be necessary or advisable in
                  connection with the authorization, issuance or sale thereof;

           (b)    the listing of the Optioned Shares on the Exchange, if 
                  applicable; and

           (c)    the receipt from the Optionee of such representations,
                  agreements and undertakings, including as to future dealings
                  in the Optioned Shares, as the Company or its counsel
                  determines to be necessary or advisable in order to safeguard
                  against the violation of the securities laws of any
                  jurisdiction.

           In this connection, the Company shall, to the extent necessary, take
all reasonable steps to obtain such approvals, registrations and qualifications
as may be necessary for the issuance of the Optioned Shares in compliance with
applicable securities laws and for the listing of the Optioned Shares on the
Exchange.

           Unless the Board at any time determines otherwise, the Option may be
exercised by the delivery of cash or cheque or other consideration acceptable to
the Company, in an amount equal to the Option Price. The Company may also permit
an Optionee to elect to pay the Option Price by authorizing a third party to
sell Shares (or 



<PAGE>   4
                                      -4-


a sufficient portion of such Shares) acquired upon exercise of the Option and
remit to the Company a sufficient portion of the sale proceeds to pay the entire
Option Price and any tax withholding resulting from such exercise.

7.3       Upon the exercise of all or any part of the Option, the Company shall
forthwith cause the registrar and transfer agent of the Company to deliver to
the Optionee or the Optionee's personal representative within a reasonable time
following the receipt by the Company of the Election to Purchase a
certificate(s) representing, in the aggregate, the number of Optioned Shares
specified in the Election to Purchase and in respect of which the Company has
received payment.

8.        Nothing herein contained shall obligate the Optionee to purchase any 
Optioned Shares except those Optioned Shares in respect of which the Optionee
shall have exercised the Option in the manner hereinbefore provided.

9.        The Optionee shall not have any rights as a shareholder of the Company
with respect to the Optioned Shares until the Optionee shall have exercised the
Option in accordance with the provisions of Paragraph 7 hereof and the Plan
(including tendering of payment in full of the Option Price of the Optioned
Shares in respect of which the Option is being exercised) and the issuance of
Optioned Shares by the Company.

10.1      If the Optionee is a resident in the United States of America, the 
Optionee recognizes and understands that Optioned Shares issued upon the
exercise of the Option will be acquired in reliance upon an exemption from the
registration requirements of the Securities Act of 1933, as amended (the "1933
ACT") pursuant to Section 3(b) and Rule 701 thereof, and hereby acknowledges and
represents that:

           (a)    The Optionee believes that the Optionee, either alone or with
                  the assistance of the Optionee's professional advisors, has
                  such knowledge and experience in financial and business
                  matters that the Optionee is capable of evaluating the merits
                  and risks of the Optionee's purchase of the Optioned Shares;

           (b)    The Optionee has sufficient financial resources to be able to
                  bear the risk of the Optionee's investment in the Optioned
                  Shares;

           (c)    The Optionee will be acquiring the Optioned Shares for
                  investment purposes only and without a current intention of
                  reselling or redistributing the same upon the occurrence or
                  non-occurrence of a predetermined event and understands that
                  the Optioned Shares being issued to him have not been, and may
                  not ever be, registered under the 1933 Act and, therefore,
                  cannot be sold unless subsequently registered under the 1933
                  Act or an exemption from registration is available;




<PAGE>   5
                                      -5-


           (d)    The Optionee has either spoken or met with, or been given
                  reasonable opportunity to speak with or meet with,
                  representatives of the Company for the purpose of asking
                  questions of, and receiving answers and information from, such
                  representatives concerning the undersigned's investment in the
                  Optioned Shares.

           (e)    The Optionee understands that the Company will rely upon the
                  representations set forth herein to claim exempt status under
                  the 1933 Act.

10.2       Certificates representing Optioned Shares issued upon exercise of the
Option by an Optionee who is a resident of the United States shall have endorsed
thereon the following legend:

                  "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
                  UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED,

                  HEREOF, BY PURCHASING SUCH SECURITIES, AGREES FOR THE BENEFIT
                  OF THE COMPANY THAT SUCH SECURITIES MAY BE OFFERED, SOLD OR
                  OTHERWISE TRANSFERRED ONLY (A) TO THE COMPANY, (B) OUTSIDE THE
                  UNITED STATES IN ACCORDANCE WITH RULE 904 OF REGULATION S
                  UNDER THE SECURITIES ACT, (C) PURSUANT TO THE EXEMPTION FROM
                  REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY RULE 144
                  THEREUNDER, IF APPLICABLE, AND IN ACCORDANCE WITH APPLICABLE
                  STATE SECURITIES LAWS OR (D) PURSUANT TO ANOTHER EXEMPTION
                  UNDER THE SECURITIES ACT AND ANY APPLICABLE STATE SECURITIES
                  LAWS, AS EVIDENCED BY AN OPINION OF COUNSEL OF RECOGNIZED
                  STANDING IN FORM ACCEPTABLE TO THE COMPANY."

10.3       For employees of a U.S. Subsidiary, this Option is intended to 
qualify as an Incentive Stock Option to the extent permitted by Section 422 of
the Code. If any portion of this Option fails to qualify as an Incentive Stock
Option under Section 422 of the Code, such portion will constitute a
Nonqualified Stock Option. To the extent that this Option constitutes an
Incentive Stock Option, the following additional terms shall apply:

           (a)    OPTION PRICE: The Option Price will be at least 100% of such
                  Option's Market Price, determined as of February 4, 1998,
                  being the date of amendment of the Plan and the effective
                  grant date (the "ISO Grant Date") of the Incentive Option. If
                  the Optionee owns more than 10% of the total voting power of
                  all classes of the Company's Shares, then the Option Price per
                  Share of an Incentive Stock Option shall not be less than 110%
                  of the Market Price of the Shares on the ISO Grant Date and
                  the Option term shall not exceed five years. The determination
                  of 10% ownership hereunder shall be made in accordance with
                  Section 422 of the Code.

                                      -6-


           (b)    ISO QUALIFICATION: To the extent that the aggregate fair
                  market value of the Shares with respect to which this Option
                  is exercisable for the first time by the Optionee during any
                  calendar year (under this Option and all other Incentive Stock
                  Options held by the Optionee) exceeds US$100,000, the excess
                  portion will be treated as a Nonqualified Stock Option, unless
                  the United States Internal Revenue Service changes the rules
                  and regulations governing the US$100,000 limit for Incentive
                  Stock Options.

           (c)    TERMINATION: Employment shall not be deemed to continue beyond
                  the first 30 days of a leave of absence unless the Optionee's
                  reemployment rights are guaranteed by statute or contract. A
                  transfer of employment or services between or among the
                  Company and its subsidiaries shall not be considered a
                  termination of employment or services.

           (d)    U.S. TAXATION OF OPTIONS. In order to obtain certain tax
                  benefits afforded to Incentive Stock Options under Section 422
                  of the Code, the Optionee must hold the Shares issued upon the
                  exercise of an Incentive Stock Option for two years after the
                  ISO Grant Date and one year from the date of exercise. The
                  Optionee may be subject to the alternative minimum tax at the
                  time of exercise. The Board may require the Optionee to give
                  the Company prompt notice of any disposition of Shares
                  acquired by the exercise of an Incentive Stock Option prior to
                  the expiration of such holding periods.

10.4       To the extent that the Optionee is, at the time of exercise of the 
Option, subject to Section 16 of the Securities Exchange Act of 1934, as amended
(the "1934 ACT") with respect to the Company, then Shares obtained upon the
exercise of the Option by such Optionee may not be sold by such person until six
months after the ISO Grant Date.

10.5       Notwithstanding the foregoing Paragraphs 10.1 and 10.2, if at the 
time of exercise of the Option the Company is subject to Section 12(b) or 12(g)
of the 1934 Act and has filed with the Securities and Exchange Commission a
registration statement on Form S-8 covering the issuance of the Optioned Shares,
then the representations set forth in Paragraph 10.1 and the legend set forth in
Paragraph 10.2 shall not apply.

11.        Nothing in the Plan or the Option shall confer upon any Optionee any 
right to continue in the employ of the Company or any Subsidiary of the Company
or affect in any way the right of the Company or any Subsidiary to terminate the
Optionee's employment at any time; nor shall anything in the Plan or the Option
be deemed or construed to constitute an agreement, or an expression of intent,
on the part of the Company or any Subsidiary to extend the employment of any
Optionee beyond the time which the Optionee would normally be retired pursuant
to the provisions of any 

<PAGE>   7
                                      -7-

present or future retirement plan of the Company or any Subsidiary, or beyond
the time at which the Optionee would otherwise be retired pursuant to the
provisions of any contract of employment with the Company or any Subsidiary.

12.        No director or officer of the Company shall be liable or be held to
account for any action taken or made in good faith under the Plan or the Option
granted pursuant hereto.

13.        Time shall be of the essence of this Agreement.

14.        This Agreement shall enure to the benefit of and be binding upon the
Company, its successors and assigns, and the Optionee and the Optionee's heirs,
executors, administrators and personal representatives to the extent provided in
Paragraph 5 hereof.

15.        Subject to Paragraph 5, this Agreement shall not be assignable or
transferable by the Optionee or the Optionee's heirs, executors, administrators
and personal representatives, and the Option may be exercised only by the
Optionee or the Optionee's heirs, executors, administrators and personal
representatives.

16.        If at any time during the continuance of this Agreement the parties 
hereto shall deem it necessary or expedient to make any alteration or addition
to this Agreement they may do so by means of a written agreement between them
which shall be supplemental hereto and form part hereof and which shall be
subject to any applicable approval by the requisite regulatory authorities
having jurisdiction.

17.        The Optionee, by the execution of this Agreement, shall be deemed to 
have (i) accepted the Option described in this Agreement and the Plan, (ii)
acknowledged receipt of a copy of this Agreement and a copy of the Plan and 
(iii) read and understood the Agreement and the Plan.

18.        Wherever the plural or masculine are used throughout this Agreement,
the same shall be construed as meaning singular or feminine or neuter or the
body politic or corporate where the context of the parties thereto require.

19.        Unless otherwise indicated, all dollar amounts referred to in this 
Agreement are in Canadian funds.

20.        This Agreement shall be governed by and construed in accordance with 
the laws of the Province of Ontario and the laws of Canada applicable therein.

21.        This Agreement may be executed in several parts in the same form and 
such parts as so executed shall together constitute one original agreement and
such parts, if more than one, shall be read together and construed as if all the
signing parties hereto had executed one copy of this Agreement.

           (HEREINAFTER CALLED THE "OPTIONEE")

                                                              OF THE SECOND PART

hereinafter provided;

           NOW THEREFORE THIS AGREEMENT WITNESSES that in consideration of the
premises and other good and valuable consideration (the receipt whereof is
hereby acknowledged) the parties hereto agree as follows:

1.        The terms of the Option granted hereunder are as set forth in this
Agreement and in the Plan. This Agreement and the Option granted hereunder shall

acknowledges that the Optionee has read and accepts the terms and conditions of
the Plan.

2.        In this Agreement, the following terms shall be defined as follows:

          (a)   "ELECTION TO PURCHASE" means a notice in writing addressed to
                the Company at its address first recited, which notice shall
                specify therein the number of Optioned Shares in respect of
                which the Option is being exercised;

          (e)   "OPTIONED SHARE" or "OPTIONED SHARES" means the common shares of
                the Company, subject to the Option.

3.        The Company hereby grants to the Optionee as an incentive and in
consideration of the Optionee's services but not in lieu of salary, the Option
to purchase a total of () Optioned Shares at an Option Price of Canadian One
Dollar and Twenty-five Cents (C$1.25) per Optioned Share at any time before 4:30
o'clock p.m., Vancouver time, on the Expiry Date. The Option granted hereunder
shall vest as to one-third of the Optioned Shares on the date of grant, i.e. on
May 9, 1997, as to a further one-third of the Optioned Shares during the
12-month period one (1) year following the date of grant, i.e. at any time
between May 9, 1998 and May 8, 1999, and as to the remaining one-third of the
Optioned Shares two (2) years following the date of grant and up to the Expiry
Date, i.e. at any time between May 9, 1999 and May 8, 2000; provided however,
that if the number of Shares taken up under the Option during any such 12-month
period is less than one-third of the Optioned Shares covered by the Option, the
Optionee shall have the right, at any time or from time to time during the
remainder of the term of the Option, to purchase such number of Shares subject
to the Option that were purchasable, but not taken up by the Optionee during
such 12-month period.

4.        The Option, to the extent that it has not been exercised shall, at 
4:30 o'clock p.m., Vancouver time, on the Expiry Date, forthwith expire and
terminate and be of no further force and effect whatsoever.

5.        In the event of the death of the Optionee on or prior to the Expiry

<PAGE>   3

Vancouver time, on the last day of the twelfth (12th) month following the day on
which the Optionee dies and, in the event the Option is in whole or in part
unexercised on the day the Optionee dies, then it is understood by the parties
that the Option may be exercised on the Optionee's behalf by the Optionee's
legal personal representative(s) of the estate of the Optionee but only to the
extent that the Optionee was entitled to exercise such Option at the date of the
Optionee's death and only prior to the Expiry Date.

6.        In the event the Optionee ceases to be a part-time or full-time 
employee, director or officer of the Company, or of any Subsidiary of the
Company as the case may be, prior to the Expiry Date the Option, to the extent
that it has not been exercised shall, at 4:30 o'clock p.m., Vancouver time, on
the thirtieth (30th) day following the day on which the Optionee ceases to be a
part-time or full-time employee, officer or director, terminate and be of no
further force or effect whatsoever. If the Optionee is a Consultant, the
Optionee's entitlement to the Option, including the termination thereof, shall
be in accordance with the terms of the consulting agreement entered into between
the Company or any Subsidiary and the Optionee, provided that in no event shall
the Option continue to be outstanding 12 months following the date upon which
such consulting agreement is terminated.

7.1       Subject to the provisions hereof and the Plan, the Option shall be
exercisable from time to time, in whole or in part, by delivery of a written
notice of exercise to the Company at the address set forth herein, accompanied
by such payment as permitted in subparagraph 7.2 hereof for the number of
Optioned Shares to be purchased as specified in such notice. Such notice shall
be in the form of an Election to Purchase, substantially in the form attached to
this Agreement as Appendix "2".

7.2       Notwithstanding any of the provisions contained in the Plan or in this
Agreement, the Company's obligations to issue Optioned Shares to the Optionee
pursuant to the exercise of the Option shall be subject to:

          (a)   completion of such registration or other qualification of such
                Optioned Shares or obtaining approval of such governmental or
                regulatory authority as counsel to the Company shall reasonably
                determine to be necessary or advisable in connection with the
                authorization, issuance or sale thereof;

          (b)   the listing of the Optioned Shares on the Exchange, if
                applicable; and

          (c)   the receipt from the Optionee of such representations,
                agreements and undertakings, including as to future dealings in
                the Optioned Shares, as the Company or its counsel determines to
                be necessary or advisable in order to safeguard against the
                violation of the securities laws of any jurisdiction.



<PAGE>   4

                                      -4-




           In this connection, the Company shall, to the extent necessary, take
all reasonable steps to obtain such approvals, registrations and qualifications
as may be necessary for the issuance of the Optioned Shares in compliance with
applicable securities laws and for the listing of the Optioned Shares on the
Exchange.

           Unless the Board at any time determines otherwise, the Option may be
exercised by the delivery of cash or cheque or other consideration acceptable to
the Company, in an amount equal to the Option Price. The Company may also permit
an Optionee to elect to pay the Option Price by authorizing a third party to
sell Shares (or a sufficient portion of such Shares) acquired upon exercise of
the Option and remit to the Company a sufficient portion of the sale proceeds to
pay the entire Option Price and any tax withholding resulting from such
exercise.

7.3       Upon the exercise of all or any part of the Option, the Company shall
forthwith cause the registrar and transfer agent of the Company to deliver to
the Optionee or the Optionee's personal representative within a reasonable time
following the receipt by the Company of the Election to Purchase a
certificate(s) representing, in the aggregate, the number of Optioned Shares
specified in the Election to Purchase and in respect of which the Company has
received payment.

8.        Nothing herein contained shall obligate the Optionee to purchase any 
Optioned Shares except those Optioned Shares in respect of which the Optionee
shall have exercised the Option in the manner hereinbefore provided.

9.        The Optionee shall not have any rights as a shareholder of the Company
with respect to the Optioned Shares until the Optionee shall have exercised the
Option in accordance with the provisions of Paragraph 7 hereof and the Plan
(including tendering of payment in full of the Option Price of the Optioned
Shares in respect of which the Option is being exercised) and the issuance of
Optioned Shares by the Company.

10.1      If the Optionee is a resident in the United States of America, the 
Optionee recognizes and understands that Optioned Shares issued upon the
exercise of the Option will be acquired in reliance upon an exemption from the
registration requirements of the Securities Act of 1933, as amended (the "1933
ACT") pursuant to Section 3(b) and Rule 701 thereof, and hereby acknowledges and
represents that:

          (a)   The Optionee believes that the Optionee, either alone or with
                the assistance of the Optionee's professional advisors, has such
                knowledge and experience in financial and business matters that
                the Optionee is capable of evaluating the merits and risks of
                the Optionee's purchase of the Optioned Shares;

          (b)   The Optionee has sufficient financial resources to be able to
                bear the risk of the Optionee's investment in the Optioned
                Shares;



<PAGE>   5

                                      -5-



          (c)   The Optionee will be acquiring the Optioned Shares for
                investment purposes only and without a current intention of
                reselling or redistributing the same upon the occurrence or
                non-occurrence of a predetermined event and understands that the
                Optioned Shares being issued to him have not been, and may not
                ever be, registered under the 1933 Act and, therefore, cannot be
                sold unless subsequently registered under the 1933 Act or an
                exemption from registration is available;

          (d)   The Optionee has either spoken or met with, or been given
                reasonable opportunity to speak with or meet with,
                representatives of the Company for the purpose of asking
                questions of, and receiving answers and information from, such
                representatives concerning the undersigned's investment in the
                Optioned Shares.

          (e)   The Optionee understands that the Company will rely upon the
                representations set forth herein to claim exempt status under
                the 1933 Act.

10.2      Certificates representing Optioned Shares issued upon exercise of the
Option by an Optionee who is a resident of the United States shall have endorsed
thereon the following legend:

                "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
                UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED, (THE
                "SECURITIES ACT") OR STATE SECURITIES LAWS. THE HOLDER HEREOF,
                BY PURCHASING SUCH SECURITIES, AGREES FOR THE BENEFIT OF THE
                COMPANY THAT SUCH SECURITIES MAY BE OFFERED, SOLD OR OTHERWISE
                TRANSFERRED ONLY (A) TO THE COMPANY, (B) OUTSIDE THE UNITED
                STATES IN ACCORDANCE WITH RULE 904 OF REGULATION S UNDER THE
                SECURITIES ACT, (C) PURSUANT TO THE EXEMPTION FROM REGISTRATION
                UNDER THE SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER, IF
                APPLICABLE, AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES
                LAWS OR (D) PURSUANT TO ANOTHER EXEMPTION UNDER THE SECURITIES
                ACT AND ANY APPLICABLE STATE SECURITIES LAWS, AS EVIDENCED BY AN
                OPINION OF COUNSEL OF RECOGNIZED STANDING IN FORM ACCEPTABLE TO
                THE COMPANY."

10.3      For employees of a U.S. Subsidiary, this Option is intended to qualify
as an Incentive Stock Option to the extent permitted by Section 422 of the Code.
If any portion of this Option fails to qualify as an Incentive Stock Option
under Section 422 of the Code, such portion will constitute a Nonqualified Stock
Option. To the extent that this Option constitutes an Incentive Stock Option,
the following additional terms shall apply:

                amendment of the Plan and the effective grant date (the "ISO
                Grant Date") of the Incentive Option. If the Optionee owns more
                than 10% of the total voting power of all classes of the
                Company's Shares, then the Option Price per Share of an
                Incentive Stock Option shall not be less than 110% of the Market
                Price of the Shares on the ISO Grant Date and the Option term
                shall not exceed five years. The determination of 10% ownership
                hereunder shall be made in accordance with Section 422 of the
                Code.

           (b)  ISO QUALIFICATION: To the extent that the aggregate fair market
                value of the Shares with respect to which this Option is
                exercisable for the first time by the Optionee during any
                calendar year (under this Option and all other Incentive Stock
                Options held by the Optionee) exceeds US$100,000, the excess
                portion will be treated as a Nonqualified Stock Option, unless
                the United States Internal Revenue Service changes the rules and
                regulations governing the US$100,000 limit for Incentive Stock
                Options.

           (c)  TERMINATION: Employment shall not be deemed to continue beyond
                the first 30 days of a leave of absence unless the Optionee's
                reemployment rights are guaranteed by statute or contract. A
                transfer of employment or services between or among the Company
                and its subsidiaries shall not be considered a termination of
                employment or services.

           (d)  U.S. TAXATION OF OPTIONS. In order to obtain certain tax
                benefits afforded to Incentive Stock Options under Section 422
                of the Code, the Optionee must hold the Shares issued upon the
                exercise of an Incentive Stock Option for two years after the
                ISO Grant Date and one year from the date of exercise. The
                Optionee may be subject to the alternative minimum tax at the
                time of exercise. The Board may require the Optionee to give the
                Company prompt notice of any disposition of Shares acquired by
                the exercise of an Incentive Stock Option prior to the
                expiration of such holding periods.

10.4      To the extent that the Optionee is, at the time of exercise of the 
Option, subject to Section 16 of the Securities Exchange Act of 1934, as amended
(the "1934 ACT") with respect to the Company, then Shares obtained upon the
exercise of the Option by such Optionee may not be sold by such person until six
months after the ISO Grant Date.

10.5      Notwithstanding the foregoing Paragraphs 10.1 and 10.2, if at the time
of exercise of the Option the Company is subject to Section 12(b) or 12(g) of
the 1934 Act and has filed with the Securities and Exchange Commission a
registration statement on Form S-8 covering the issuance of the Optioned Shares,
then the representations set forth in Paragraph 10.1 and the legend set forth in
Paragraph 10.2 shall not apply.

to this Agreement they may do so by means of a written agreement between them
which shall be supplemental hereto and form part hereof and which shall be

                           Adjustments;

                  the direction or order of the Vendors or third parties;

       (b)        an amount equal to $1,500,000 shall be deposited with the

3.4               ALLOCATION OF PURCHASE PRICE.  The Purchase Price for the

be agreed upon between the Vendors, the Committee and





                                     - 27 -
<PAGE>   28
the Purchaser prior to Closing, after taking into account Section 1060 of the
Internal Revenue Code, the applicable Treasury Regulations and the respective
fair market values of the Purchased Assets, based on the relative fair market
value of such assets, but in any event shall provide for the allocation of such
portion of the Purchase Price to EFN to reflect the reasonably equivalent
value, if any, of such Purchased Assets owned by EFN.  The Vendors and the
Purchaser agree to report the sale and purchase of the Purchased Assets for all
federal, state, provincial and local tax purposes in a manner consistent with
such allocation.  If the Vendors, the Committee and the Purchaser are unable to
agree on an allocation of the Purchase Price prior to Closing, the matter shall
be referred to the Bankruptcy Court for resolution.  The Vendors shall provide
information that may be reasonably required by the Purchaser for the purpose of
preparing any returns that may be required with respect to the transaction
provided for herein pursuant to Section 1060 of the Internal Revenue Code, any
Treasury Regulations promulgated thereunder, any other similar provision of the
Internal Revenue Code and any other similar, applicable foreign, state or local
tax law or regulation.

3.5               DEDUCTIONS FROM HOLDBACK.  If the Purchaser has identified a
Holdback Claim against any of the Vendors for any breach of representation,
warranty, covenant or other obligation under this Agreement, on or before the
first anniversary of the Closing Date, and gives notice in writing to the
Vendors and the Escrow Agent to that effect, specifying in reasonable detail
the nature of the Holdback Claim and specifying the amount that the Purchaser
reasonably considers to be necessary to satisfy the amount of the Holdback
Claim, the Escrow Agent shall retain such amount together with interest
accruing thereon in escrow pursuant to the Escrow Agreement until the validity
and amount of the Holdback Claim is determined by agreement between the parties
or by a court, at which time the amount of the Holdback Claim, to the extent
funds are then held in escrow, shall be provided to the Purchaser to the extent
so agreed or determined by the Court.  Upon the first anniversary of the date
hereof, the Escrow Agent shall disburse all amounts then held in escrow to the
Vendors except for those amounts set aside to satisfy unresolved Holdback
Claims, which shall be disbursed upon the agreement of the parties or the
Court's determination of the validity and amount of each such Holdback Claim;
all pursuant to the Escrow Agreement.  The amount of any unresolved Holdback
Claim, when so determined, shall be payable to the Purchaser plus accrued
interest thereon and the remainder of the escrow funds, if any, to the Vendors.
If any such Holdback Claims are so determined to be payable to the Purchaser,
the Purchase Price shall be adjusted accordingly.  The amount payable to the
Purchaser for all such claims plus all accrued interest thereon shall not
exceed $1,500,000 in aggregate plus all accrued interest thereon (except for
any Claim relating to the Vendors' obligation to pay all remaining Liabilities
of the Subsidiaries not assumed by the Purchaser, which Claims shall not be
limited).  No Holdback Claim (other than a Claim relating to the Vendors'
obligation to pay all remaining Liabilities of the Subsidiaries not assumed by
the Purchaser) shall be allowed unless





                                     - 28 -

it is submitted within 12 months of the Closing Date and the alleged breach of
the representation or warranty or covenant accrued prior to the end of such 12-
month period.

3.6               ADJUSTMENTS TO PURCHASE PRICE.  The Purchase Price shall be
adjusted in the following circumstances:

       (a)        to reflect any payments to the Purchaser under the Escrow
                  Agreement; and

       (b)        by adjusting for any amounts referred to in paragraph 3.7.

3.7               ADJUSTMENTS.  The Vendors and the Purchaser will make
Purchase Price adjustments as follows:

       (a)        The Purchase Price will be reduced by the following amounts:

                           the amount of the gross proceeds of the sale of any
                           Equipment, Lands, Supplies, or Mineral Rights that

                           as liquidated damages, it being agreed that this is
                           a fair and reasonable estimate of the replacement
                           cost of such assets;

                   (ii)    100% of the gross proceeds of the sale of any U308
                           derived from the Processing Contract, other than any

                           Contract;

                   (iii)   any net profits realized by the Purchaser between

       (e)        CONFLICTING RIGHT OR INTEREST.  To the best of the knowledge
                  of the Vendors there is no right or interest in any of the

                  the United States: (i) in the case only of Mineral Rights
                  located by the Vendors or the Subsidiaries, the Mineral
                  Rights were properly laid out and monumented; (ii) in the
                  case only of Mineral Rights located by the Vendors or the
                  Subsidiaries, all required location and validation work was
                  properly performed; (iii) in the case only of Mineral Rights
                  located by the Vendors or the Subsidiaries, location notices
                  and certificates were properly recorded and filed with
                  appropriate governmental agencies; (iv) all assessment work
                  or payment in lieu thereof required to hold the Mineral
                  Rights has been performed through the most recent assessment
                  year and up to the date hereof; (v) all assessment work
                  required to hold the mining claims through the most recent
                  assessment year and up to the date hereof has been or will be
                  timely performed by the Vendors or the Subsidiaries prior to
                  Closing; and (vi) all affidavits of assessment work and other
                  filings required to maintain the Mineral Rights in good
                  standing have been properly and timely recorded and filed
                  with appropriate governmental agencies except for certain
                  assessment work notices filed with the State of Utah in 1995
                  and associated with the Bradford Litigation.  Provided,
                  however, that the Vendors shall not be in breach of this
                  representation and warranty as to unpatented mining claims on
                  account of any determination of any court or governmental
                  agency that the work performed as assessment work did not
                  constitute the required annual assessment work or occupancy
                  for the purposes of preserving or maintaining ownership of
                  the unpatented mining claims, provided that the work done was
                  of the kind generally accepted in the mining industry as
                  assessment work under existing law.

       (g)        NO DEFECTS, LIENS OR ENCUMBRANCES.  There are no defects,
                  liens or Encumbrances (other than Permitted Encumbrances)
                  that will have a material adverse effect on the Mineral
                  Rights, that will not be otherwise discharged or released
                  prior to or at Closing, provided however, nothing contained
                  herein shall be deemed to be a representation or warranty
                  that any of the unpatented mining claims has a discovery of
                  mineral resources within its respective boundaries.

       (h)        LANDS:  To the best of the knowledge of the Vendors, the list
                  of Lands set out in Schedule "F" accurately reflects all fee
                  simple interests of the Vendors and the Subsidiaries in real
                  property (other than patented mining claims) used in the
                  conduct of the Business.

       (i)        EQUIPMENT:  To the best of the knowledge of the Vendors, the
                  list of Equipment set out in Schedule "B" accurately
                  describes the Equipment and other personal property owned by
                  the Vendors or the

                  forth on Schedule B free of all Encumbrances except for
                  Permitted Encumbrances.

       (j)        ENCROACHMENTS:  To the best of the knowledge of the Vendors,
                  all Lands and Buildings owned by the Vendors or Subsidiaries
                  are located wholly within the boundaries of the Lands and do
                  not infringe upon or contravene the provisions of any
                  easement, right of way or encumbrance registered against or
                  otherwise affecting the Lands, and there are no buildings,
                  fixtures, improvements or facilities on any adjoining lands,

                  Creek has not yet been permitted by the State of Wyoming or
                  the Nuclear Regulatory Commission and that the Purchaser will
                  have to comply with any additional laws or regulations
                  applicable to any Permit or License that have been
                  promulgated by governmental agencies after the issuance of
                  such Permit or License, and with any laws or regulations
                  applicable to the transfer of the Permits and Licenses, prior

                  and are conducting the Business, in compliance with all
                  applicable laws and regulations of each jurisdiction in which

                  Business.  Except as set out in Section 4.2.6, the Vendors

                  Liabilities (whether accrued, contingent, absolute or

                  including Liabilities relating to Taxes, except:

                   (i)     Liabilities listed in Schedules and Statements  of
                           Financial Affairs filed in the Jointly Administered

                   (iii)   Liabilities in the amounts and to the persons
                           described in Schedule "L" hereto; or

                   (iv)    Liabilities disclosed in this Agreement, including
                           but not limited to Liabilities under or in

                           the Term Loan and the Dissolution Agreement

                  The inclusion of an obligation or purported obligation on any
                  schedule attached hereto does not constitute an admission by
                  any of the Vendors that such obligation or purported
                  obligation is in fact valid or that  any of the Vendors are
                  liable on such obligation.

       (b)        NO BROKERS:  Neither the Vendors nor the Subsidiaries have
                  incurred any Liability and will incur no Liability,
                  contingent or otherwise, for broker's or finder's fees in
                  connection with this transaction for which the Purchaser
                  shall have any responsibility whatsoever.

       (c)        LIABILITIES OF THE SUBSIDIARIES:  As of the Closing Date, all
                  Liabilities (except for Assumed Obligations) of the
                  Subsidiaries shall have been paid in full or reserved for as
                  set forth herein.  The Vendors shall place in trust from the
                  proceeds of sale of the Purchased Assets an amount sufficient
                  to satisfy all such Liabilities which may exist after the
                  Closing Date.  The amount the Vendors place in trust shall be
                  no less than the sum of:

                   (i)     all known and asserted, but disputed or otherwise
                           unpaid, Liabilities of the Subsidiaries; and

                   (ii)    such other sums as the Vendors using reasonable
                           business judgment determine is necessary to satisfy
                           any other unpaid Liabilities (which

                           are not assumed by Purchaser) or other amounts owing
                           or reasonably expected to be owing by the
                           Subsidiaries, including, without limitation,
                           unliquidated or contingent Liabilities.

                  These sums shall remain in trust to satisfy the Claims of all
                  holders of a Liability or such other amounts against the
                  Subsidiaries until all such Liabilities are satisfied in full
                  or the Bankruptcy Court enters an order authorizing the
                  disbursal or reduction of such trust funds.  The Swiss
                  Utilities, but no other parties, shall be considered as third

           SECTION 5 - REPRESENTATIONS AND WARRANTIES OF THE PURCHASER

5.1               REPRESENTATIONS AND WARRANTIES OF THE PURCHASER.  The
Purchaser represents, warrants and covenants to the Vendors as follows and
acknowledges that the Vendors are relying upon the following representations,
warranties and covenants in connection with the sale of the Purchased Assets
and Business:

       (a)        STATUS OF PURCHASER:  The Purchaser is a duly incorporated
                  and validly existing corporation in good standing under the
                  laws of the State of Delaware and has the corporate power and
                  capacity to carry out the transactions contemplated by this
                  Agreement.

       (b)        DUE AUTHORIZATION:  The execution and delivery of this
                  Agreement and the completion of the transactions contemplated
                  hereby have been duly authorized by all necessary corporate
                  action on the part of the Purchaser, and this Agreement has
                  been duly executed and delivered by the Purchaser and
                  constitutes a legal, valid and binding obligation of the
                  Purchaser enforceable in accordance with its terms.

       (c)        NON-CONTRAVENTION:  Neither the execution, delivery and
                  performance of this Agreement nor the completion of the
                  transactions contemplated hereby will conflict with or result
                  in a breach of or default under any agreement or other
                  instrument or obligation to which the Purchaser is a party or
                  by which the Purchaser is bound.

       (d)        LITIGATION:  There are no actions, suits, judgments,
                  litigations, investigations, proceedings, consent decrees or
                  settlement agreements outstanding, pending or threatened
                  against or affecting the Purchaser which would prevent the
                  Purchaser from entering into this Agreement and completing
                  the transactions contemplated hereby.

       (e)        FINANCIAL CAPABILITY:  The Purchaser has or has access to
                  sufficient funds in order to close the transaction
                  contemplated by this Agreement and provide adequate assurance
                  of future performance for all Assumed Obligations.  The
                  Purchaser will, on the Closing Date, have at least:

                     (i)   $30,000,000 in working capital (which working
                           capital may consist of subordinated debt); and

                   (ii)    a Book Value of $30,000,000;

                  for the purpose of paying the Purchase Price and operating
                  the Business; provided, however, if at Closing or subsequent
                  thereto, the Purchaser transfers or assigns the Mongolian
                  Joint Venture Interests (or grants or conveys the right to be
                  transferred the Mongolian Joint

                  Venture Interest) to a nominee which is not a wholly owned
                  subsidiary of the Purchaser, then the Purchaser will either:
                  (x) increase the minimum amount of such working capital and
                  Book Value on the Closing Date to $35,000,000 or, if the
                  transfer occurs after the Closing Date, increase the working
                  capital on the date of such transfer, by $5,000,000; or (y)
                  arrange for the nominee (or the nominee's parent company)
                  which obtains the Mongolian Joint Venture Interest to
                  guarantee payment and performance of the Purchaser's
                  obligations hereunder.  For greater   certainty, subject to
                  paragraph 6.5(c) below, the Purchaser shall not be required
                  to maintain any level of working capital or Book Value
                  subsequent to the Closing, or if $5,000,000 is added to the
                  working capital pursuant to clause (x) of paragraph
                  5.1(e)(ii), subsequent to the date such working capital is
                  added.

       (f)        NO BROKERS:  The Purchaser has incurred no Liability and will
                  incur no Liability, contingent or otherwise, for broker's or
                  finder's fees in connection with this transaction for which
                  the Vendors shall have any responsibility whatsoever.

       (g)        INVESTMENT EXPERIENCE OF PURCHASER:  The Purchaser's
                  principals and their advisors have experience in these types
                  of transactions and as a result the Purchaser is fully
                  capable of evaluating the transactions contemplated by this
                  Agreement.


                             SECTION 6 - COVENANTS

6.1               OPERATIONS UNTIL CLOSING.  Except as otherwise provided in

                  the ordinary course, consistent with past practice and, in
                  particular:

                     (i)   will use all reasonable efforts to maintain the
                           Purchased Assets in accordance with standard
                           industry practice;

                  (ii)     except with respect to Permitted Encumbrances, will
                           not mortgage, pledge, subject to lien or otherwise
                           encumber the Purchased Assets in whole or in part or
                           sell, transfer or dispose of, or agree to dispose
                           of, any of the Purchased Assets;

                   (iii)   use all reasonable efforts to keep available the
                           services of the present employees of the





                                   - 45 -

                           Vendors and the Subsidiaries and to maintain the
                           relations and goodwill with suppliers, customers and
                           others having relations with the Vendors or the
                           Subsidiaries;

                  (iv)     the Vendors will not sell any U308 derived from the
                           performance of the Processing Contract at any time
                           prior to December 23, 1996, except for U3O8 used to
                           pay the transportation costs directly associated
                           with the Processing Contract;

                   (v)     if the Bridge Loan is not funded by December 23,
                           1996, the Vendors shall have the right to sell U308
                           derived from the Processing Contract provided that
                           the Vendors grant the Purchaser with a right of
                           first refusal to purchase such U3O8, except for U3O8
                           used to pay the transportation costs directly
                           associated with the Processing Contract.  Prior to
                           selling any such U3O8, the Vendors shall furnish to
                           the  Purchaser, in writing, the proposed terms and
                           conditions of such sale of U3O8.  Within five
                           business days after receipt of the terms and
                           conditions of the proposed sale, the Purchaser shall
                           notify the Vendors, in writing, if it wishes to
                           exercise its right of first refusal and thereby
                           purchase the U3O8.  If the Purchaser fails to
                           exercise its right of first refusal within five
                           business days after its receipt of the terms and
                           conditions of a proposed sale of the U3O8, the
                           Purchaser shall be deemed to have rejected its right
                           of first refusal with respect to the proposed sale;

                   (vi)    will not negotiate or enter into or terminate, prior
                           to its expiration, any Material Contract;

                   (vii)   will not pay any dividends or make any other
                           distributions in respect of capital stock or repay
                           any debts to affiliated entities;

                   (viii)  will not fail to make any property or joint venture
                           payment that is due and payable prior to the
                           Effective Date except for those expressly disclosed
                           in this Agreement;

                   (ix)    will not close the transaction set out in the URI
                           Agreement; and

                   (x)     if Closing occurs before January 31, 1997, will not
                           enter into any sales agreements with purchasers of
                           U308 from time to time which





                                   - 46 -

                           match EFEX's purchase obligations under the Cameco
                           Agreement after January 1, 1997

                  unless otherwise agreed to in writing by the Purchaser.
                  Notwithstanding that Section 3.7 of this Agreement provides
                  an adjustment mechanism for certain sales of Purchased
                  Assets, any activities that violate this paragraph (a) shall
                  be considered a breach of this Agreement.  However, if the
                  Purchaser agrees in writing to an activity in violation of
                  this paragraph (a), then the adjustment mechanism set out in
                  Section 3.7 of this Agreement shall apply.  However,
                  Purchaser will not unreasonably withhold consent with respect
                  to any matters above except those matters set forth in
                  subsections iv,v and ix, provided that the value of the
                  Purchased Assets is not materially affected.

       (b)        NEW CAPITAL PROJECTS:  not, without the Purchaser's prior
                  written consent or unless required by law or required to
                  repair or replace any loss or damage to the Purchased Assets
                  arising subsequent to the execution of this Agreement,
                  commence or commit to any new capital projects or make any
                  capital or exploration expenditures except Permitted Capital
                  Expenditures;

       (c)        AGREEMENTS:  not, without the prior written consent of the
                  Purchaser, amend or vary any of the Material Contracts, the
                  Permits and Licenses or the Mineral Rights or enter into any
                  agreement or lease or obtain any additional permit, right of
                  way, license or other similar right in connection with the
                  Business or Purchased Assets except:

                   (i)     renewals or replacements of any of the Permits and
                           Licenses or Surety Bonds on substantially the same
                           terms and conditions; and

                   (ii)    any additional permits, leases, rights-of-way,
                           licenses or similar rights obtained or entered into
                           in the ordinary course of the Business, consistent
                           with past practice, or as required by law;

       (d)        INSURANCE:  maintain and cause the Subsidiaries to maintain
                  in full force and effect the insurance coverage described in
                  Schedule "M", and the Vendors or the Subsidiaries shall pay
                  all premiums in connection with such insurance coverage and
                  shall not act or fail to act so as to invalidate such
                  insurance coverage; the proceeds of any such insurance which
                  shall become payable as a result of any physical loss or
                  damage to the Purchased Assets or any part of the Purchased
                  Assets after the date of this Agreement until the Closing
                  Date, to the extent not applied to the repair or replacement
                  of such





                                   - 47 -
<PAGE>   48
                  Purchased Assets prior to the Closing Date, shall be deemed
                  to be included as part of the Purchased Assets, and the
                  parties to this Agreement agree that any such insurance
                  proceeds and all rights in respect of such insurance proceeds
                  shall from the date of execution of this Agreement be held in
                  trust for the Purchaser by the Vendors and the Subsidiaries
                  and shall be assigned by the Vendors to the Purchaser in
                  respect of and in replacement for any of the Purchased Assets
                  or any part of the Purchased Assets lost, destroyed or
                  damaged by any of the causes in respect of which the policies
                  of insurance are maintained; the Vendors shall take all
                  necessary steps to the satisfaction of the Purchaser, acting
                  reasonably, to ensure that any assignments of the benefits of
                  insurance in respect of the Purchased Assets in favor of any
                  party other than the Purchaser or its nominee or nominees by
                  either of them are subject to and subordinate to the interest
                  and entitlement of the Purchaser or its nominee or nominees
                  to proceeds of such insurance as provided in this Agreement;

       (e)        ACCESS:  subject to the provisions of the confidentiality
                  agreement that has been executed by the Purchaser relating to
                  the Business and the Purchased Assets, provide to the
                  Purchaser, its employees, representatives and agents access
                  during normal business hours to the facilities, properties
                  and all books, accounts, data and records relating to the
                  Business or the Purchased Assets, including electronically
                  stored data and records, and to the Vendors' and
                  Subsidiaries' personnel including, without limitation, all
                  financial and operating data relating to the Business or the
                  Purchased Assets and all, or true copies of all, title
                  documents, contracts, agreements, mortgages, instruments,
                  leases and other documents relating to the Purchased Assets
                  or the Business as the Purchaser from time to time reasonably
                  requests.

       (f)        COOPERATION/PRE-CLOSING ACTIVITIES:  to facilitate Closing on
                  or before December 31, 1996 or as soon as possible, the
                  Vendors shall have commenced pre-closing activities

                  interests in contracts, licenses, and joint venture interests
                  (including consents and approvals, if any needed for the
                  Nuclear Regulatory Commission, the parties to the Mongolian

6.2               REBUILDING FACILITIES.  In the event of any loss or
destruction of the Purchased Assets in whole or in part after the date of this
Agreement and up to the Closing, the Vendors and the Purchaser shall negotiate
in good faith to agree upon the application of any proceeds of insurance to
rebuilding, repairing or replacement of the lost or destroyed Purchased Assets
in the best interests of the maintenance and continuation of the Business, and
in accordance with the plans of the Purchaser for the Purchased Assets and
Business.  If the Purchaser and the Vendors are unable to agree upon the
application of such proceeds, the proceeds shall be held by the Vendors and
conveyed to the Purchaser at Closing.

6.3               REQUESTS FOR CONSENTS.  The Vendors and the Purchaser will
use all reasonable efforts to obtain, prior to Closing:

       (a)        all consents and approvals necessary for the assignment of
                  the Vendor's interest in the Contracts, the Permits and
                  Licenses and the Surety Bonds to the Purchaser; or

       (b)        if applicable, the re-issuance of any one or more of the
                  Contracts, Permits and Licenses and Surety Bonds in the name
                  of the Purchaser or its nominee or nominees,

and the Vendors will not, except as presently contemplated by the terms thereof
or with the prior written consent of the Purchaser, agree to any amendment or
variation to the terms of such Contracts, Permits and Licenses or Surety Bonds
in connection with, or as a condition of, such assignment or re-issuance.

6.4               AGREEMENTS REQUIRING CONSENT.  Where a consent of a third
party is required to permit the transfer or assignment to the Purchaser of any
of the Vendors' interest in any of the Contracts, Permits and Licenses or
Surety Bonds, the assignment of those agreements and rights in respect of which
the required consent has not been received on or before the Closing Date will
not be effective in each case until the applicable consent has been received or
the Bankruptcy Court enters an order authorizing the Vendors to assume such
agreement and assign it to the Purchaser and, in the absence of such consent or
Bankruptcy Court Order, such agreement or right will be held by the Vendors
following the Closing in trust for the benefit and exclusive use of the
Purchaser.  The Vendors shall continue to use all reasonable efforts to obtain
the required consents.  The Vendors shall only make use of such agreements and
rights in accordance with the directions of the Purchaser that do not conflict
with the terms of such Contracts, Permits and Licenses or Surety Bonds provided
that the Purchaser shall reimburse the Vendors for all reasonable costs and
expenses incurred as a result of the direction of the Purchaser.

6.5               PURCHASER'S COVENANTS.

       (a)        GENERAL: The Purchaser will, prior to and on the Closing
                  Date, use all reasonable efforts to obtain all consents in
                  form and substance reasonably satisfactory to the Purchaser.

       (b)        CAPITAL STRUCTURE: The Purchaser will, on the Closing Date,
                  have at least:

                   (i)     $30,000,000 in working capital (which working
                           capital may consist of subordinated debt); and

                   (ii)    a Book Value of $30,000,000

                  for the purpose of paying the Purchase Price and operating
                  the Business; provided, however, if at Closing or subsequent
                  thereto, Purchaser transfers or assigns the Mongolian Joint
                  Venture Interests (or grants or conveys the right to be
                  transferred the Mongolian Joint Venture Interest) to a
                  nominee which is not a wholly owned subsidiary of Purchaser,
                  then Purchaser will either: (x) increase the minimum amount
                  of such working capital and Book Value on the Closing Date to
                  $35,000,000 or, if the transfer occurs after the Closing
                  Date, increase the working capital on the date of such
                  transfer, by $5,000,000; or (y) arrange for the nominee (or

                  Joint Venture Interest to guarantee payment and performance
                  of Purchaser's obligations hereunder.  For greater certainty,
                  subject to paragraph 6.5(c) below, Purchaser shall not be
                  required to maintain any level of working capital or Book
                  Value subsequent to the Closing, or if $5,000,000 is added to
                  the working capital pursuant to clause (x) of paragraph
                  6.5(b)(ii), subsequent to the date such working capital is
                  added.

       (c)        TRANSFER RESTRICTIONS:  At any time during the one-year
                  period after the Closing, without the consent of the Vendors,
                  acting reasonably, the Purchaser will not:

                   (i)     on account of any debt to any parent company or
                           other affiliated entities, repay any principal sums
                           due thereunder; or

                   (ii)    in the case of equity, make any capital
                           distributions,

                  other than from net income or profits, unless at the time of
                  and after giving effect to such repayment or distribution,
                  the Purchaser has a Book Value in excess of $30,000,000.

       (d)        NOMINEE ENTITIES:    The Purchaser shall be responsible for

The foregoing conditions are inserted for the mutual benefit of the Vendors and
the Purchaser and may be waived in whole or in part only if jointly waived by

                           referred to in paragraph 3.3(b), to protect the
                           Purchaser if the Permit or License is not
                           transferred within a reasonable amount of time after

change to the Purchase Price and/or an additional holdback (over and above the
holdback referred to in paragraph 3.3(b) to compensate for the failure of such
condition or conditions being satisfied.

contracts and unexpired leases.

under this Agreement with respect to any claims, the Vendors will indemnify and
save the Purchaser harmless from and against all losses, costs, damages,
expenses, penalties and Liabilities suffered or incurred by the Purchaser or
its nominee or nominees:

       (a)        by reason of a breach of any representation, warranty,
                  covenant or agreement of the Vendors set forth in this
                  Agreement;

       (b)        arising out of or in connection with any Liabilities or
                  obligations of the Vendors that are not Assumed Obligations
                  by the Purchaser pursuant to this Agreement relating to the
                  Business or any of the Purchased Assets; and

       (c)        arising out of or in connection with any Liabilities of the
                  Subsidiaries which are not Assumed Obligations.

For greater certainty, the indemnity obligations of the Vendors to the
Purchaser shall be limited to the Holdback Amount except for claims arising
under paragraph 11.2(c) which shall be unlimited.

11.3              INDEMNITY BY THE PURCHASER:  Subject to the limitations set
forth in paragraphs 11.1 and 11.5, in addition to any rights the Vendors have
under this Agreement with respect to any claims, the Purchaser will indemnify
and save the Vendors harmless from and against all losses, costs, damages,
expenses, penalties and Liabilities suffered or incurred by the Vendors:

       (a)        by reason of a breach of any representation, warranty,
                  covenant or agreement of the Purchaser set forth in this
                  Agreement; and

       (b)        arising out of or in connection with any obligations
                  comprising the Assumed Obligations.

11.4              DEFENSE OF INDEMNITY CLAIMS.  In the event of a claim (an
"Indemnity Claim") being made by a third party against a party hereto (the
"Indemnified Party") in respect of which another party (the "Indemnifier") has
covenanted to indemnify the Indemnified Party, the following provisions shall
apply.





                                   - 68 -
<PAGE>   69
                  The Indemnified Party shall promptly give notice to the
Indemnifier of any Indemnity Claim in respect of which the Indemnified Party
intends to claim for indemnification against the Indemnifier under this
Agreement.  Such notice shall specify with reasonable particularity (to the
extent that the information is available) the nature of the Indemnity Claim.
The Indemnifier shall, at its own expense, assume control of the negotiation,
settlement and defense of such Indemnity Claim.  The Indemnified Party shall
cooperate with the Indemnifier in respect of such Indemnity Claim, and the
Indemnifier shall reimburse the Indemnified Party for all the Indemnified
Party's reasonable expenses as a result of the Indemnifier's assumption of such
Indemnity Claim and arising from the Indemnified Party's cooperation.  The
Indemnified Party shall have the right to participate in the negotiation,
settlement and defense of such Indemnity Claim at its own expense and shall
have the right to disagree on reasonable grounds with the selection and
retention of counsel, in which case counsel satisfactory to the Indemnifier and
the Indemnified Party shall be retained by the Indemnifier.  If the Indemnifier
fails to defend any Indemnity Claim within a reasonable time, the Indemnified
Party shall be entitled to assume control of the Indemnity Claim at the expense
of the Indemnifier, and the Indemnifier shall be bound by the results obtained
by the Indemnified Party with respect to such Indemnity Claim.

11.5              EXTENT OF HOLDBACK CLAIMS.  Any Holdback Claims made by the
Purchaser for any breaches of representation, warranty, covenant or agreement
of the Vendors contained herein or for indemnification shall be limited in
aggregate to the $1,500,000 deposited with the Escrow Agent under the Escrow
Agreement plus accrued interest except for any Holdback Claims in connection
with any Liabilities of the Subsidiaries which are not Assumed Obligations,
which such claims shall be unlimited.  However, the parties agree that the
party substantially prevailing in any disputed Holdback Claim shall be entitled
to reimbursement for reasonable attorney's and other professional's actual fees
and disbursements incurred in prosecuting or defending any disputed Holdback
Claim. If the Claim is determined, as to liability, partially, but not
substantially in favor of the Purchaser and partially, but not substantially in
favor of the Vendors, or the amount of the Holdback Claim is decided somewhere
between the amount claimed by the Purchaser and Vendors but not substantially
in favor of either the Purchaser or the Vendors, then the court or other
appropriate authorities that made the determination shall apportion such fees
and expenses fairly between the parties.

11.6              ADDITIONAL RULES AND PROCEDURES.  The following provisions
shall also apply with respect to Indemnity Claims:

       (a)        In the event that any Indemnity Claim is of a nature such
                  that the Indemnified Party is legally bound or required by
                  applicable law to make a payment to any person (a "Third
                  Party") with respect to such Indemnity Claim before the
                  completion of settlement negotiations or related legal
                  proceedings, including without limitation,

                  the posting of any security to stay any process of execution
                  or judgment, the Indemnifier shall, subject to the
                  limitations set forth in paragraph 11.5 be obligated to make
                  such payment or post security therefor, on behalf of the
                  Indemnified Party.  If the Indemnifier fails to do so, the
                  Indemnified Party may make such payment or post security
                  therefor and the Indemnifier shall, forthwith after demand by
                  the Indemnified Party, reimburse the Indemnified Party for
                  any such payment or cause the security to be replaced and
                  released.  If the amount of any liability of the Indemnified
                  Party under the Indemnity Claim in respect of which such a
                  payment was made, as finally determined, is less than the
                  amount which was paid by the Indemnifier to the Indemnified
                  Party, the Indemnified Party shall, forthwith after receipt
                  of the difference from the third party, pay the amount of
                  such difference to the Indemnifier.

       (b)        Except in the circumstance contemplated by paragraph 11.6(a),
                  or unless the Indemnifier fails to assume control of the
                  negotiation, settlement and defense of any Indemnity Claim,
                  the Indemnified Party shall not negotiate, settle, compromise
                  or pay any Indemnity Claim except with the prior written
                  consent of the Indemnifier (which consent shall not be
                  unreasonably withheld).

       (c)        The Indemnified Party shall not permit any right of appeal in
                  respect of any Indemnity Claim to terminate without giving
                  the Indemnifier notice thereof and an opportunity to contest
                  such Indemnity Claim.

       (d)        The Indemnified Party and the Indemnifier shall cooperate
                  fully with each other with respect to Indemnity Claims, shall
                  keep each other fully advised with respect thereto (including
                  supplying copies of all relevant documentation promptly as it
                  becomes available) and shall each designate a senior officer
                  who will keep himself informed about and be prepared to
                  discuss the Indemnity Claim with his counterpart and with
                  counsel at all reasonable times.

       (e)        Notwithstanding anything else in this paragraph 11.6, the
                  Indemnifier shall not settle any Indemnity Claim or conduct
                  any related legal or administrative proceeding in a manner
                  which would, in the opinion of the Indemnified Party, acting
                  reasonably, have a material adverse impact on the Indemnified
                  Party.

       (f)        The provisions of paragraph 11.4 and this paragraph 11.6 are
                  intended to set out the procedures to be followed with
                  respect to an Indemnity Claim and, provided the Indemnified
                  Party follows such procedures in all material respects,
                  nothing contained in paragraph 11.4 and this paragraph 11.6
                  shall derogate from the Indemnifier's obligations to
                  indemnify the Indemnified Party as otherwise provided in this
                  Agreement.

11.7              COOPERATION AND EXCHANGE OF INFORMATION.  The Vendors, the
Subsidiaries and the Purchaser shall provide each other with such cooperation
and information as any of them reasonably may request of the others in
connection with their respective business operations including, without
limitation, litigation matters, accounting matters, filing any Tax Return,
determining a liability for Taxes or a right to a refund of Taxes or in
conducting any audit or proceeding in respect of Taxes.  Such cooperation and
information shall include, without limitation, providing copies of relevant Tax
Returns or portions thereof, together with accompanying schedules and related
work papers and documents relating to rulings or other determinations by Taxing
authorities.  Each party shall make its employees available on a mutually
convenient basis to provide explanation of any documents or information
provided hereunder. Each party shall, upon written request from the other
party, provide such factual information reasonably necessary for litigation
matters, accounting matters, filing Tax Returns, Tax planning, contesting any
Tax audit or for such other reasonable purposes.  In addition, if the Purchaser
intends to offer employment to a former employee of the Vendors, the Vendors
shall, at the request of the Purchaser, provide the Purchaser with any records
or files relative to any such former employee.  Vendors shall maintain and
safeguard all information relating to accounting matters, Tax returns, Tax
planning, contesting Tax amounts or litigation and all files relating to former
employees and shall not destroy it without at least 30 days prior written
notice to Purchaser.

       Any information or copies thereof retained or acquired by the Vendors
that relates to any of the Purchased Assets or Business shall be maintained as
confidential by the Vendors and shall not be used by the Vendors for any
purpose that would be contrary to the interests of or competitive with the
Purchaser or that would impair the value to the Purchaser of any of the
Purchased Assets or the Business.  Any such information shall cease to be
confidential if such information has been publicly disseminated other than as a
result of disclosure by any of the Vendors or by their directors, officers,
shareholders, owners, agents or representatives.

11.8              DISPUTE RESOLUTION.  Unless otherwise specifically set forth
herein, for any dispute concerning the terms of this Agreement or either
party's performance hereunder which the parties have failed to resolve by good
faith negotiation, the following procedure shall apply:

       (a)        the dispute shall be submitted to the jurisdiction of the
                  Bankruptcy Court for resolution; and

       (b)        if the Bankruptcy Court declines jurisdiction, then the
                  dispute shall be resolved by the following arbitration
                  procedures:





                                   - 71 -
<PAGE>   72
                   (i)     Either party may serve a demand for arbitration upon
                           the other party, naming an arbitrator, via certified
                           mail.  The party upon which the demand is served
                           shall serve a response upon the party serving the
                           demand naming a second arbitrator, within 30 days
                           after receipt of said demand.  The two arbitrators
                           shall name a third arbitrator and, upon their
                           failure to do so within 15 days after the naming of
                           the second arbitrator, the third arbitrator shall be
                           named by the American Arbitration Association
                           ("AAA"), Denver, Colorado.

                   (ii)    The parties shall submit an agreed-upon statement of
                           issues to the arbitrators within 30 days after the
                           third arbitrator is selected, or, if they cannot
                           agree upon the issues, each party shall submit its
                           proposed statement of issues.  Within 30 days after
                           the statement(s) of issues is filed, each party
                           shall submit a list of witnesses whom it intends to
                           call at the hearing, including a summary of
                           testimony which each witness will give at the
                           hearing.  The parties may amend said list at any
                           time prior to 30 days before trial.  In no event
                           shall either party be allowed to call a witness who
                           is not included in that party's witness list.

                   (iii)   Before the hearing, the parties shall have the
                           opportunity to conduct reasonable discovery, which
                           shall include written interrogatories and requests
                           for admissions, document exchanges and limited
                           depositions; provided, however, that each party
                           shall only be allowed four depositions, 25
                           interrogatories (including all discrete subparts) 25
                           requests for production of documents and ten
                           requests for admissions or such other discovery
                           reasonably approved by the arbitrator.

                   (iv)    The arbitration shall be conducted pursuant to the
                           Commercial Arbitration Rules of the AAA.  The
                           arbitrators shall render a decision in writing based
                           upon the statement(s) of issues submitted by the
                           parties, the evidence presented at the hearing, the
                           Agreement, and the laws of the State of Colorado.

                   (v)     Pending a decision by the arbitrators, the Agreement
                           shall remain in full force and effect and each party
                           shall fully perform its obligations under the
                           Agreement without prejudice to the dispute which is
                           being

                           arbitrated, to the extent such performance is
                           practicable.

the Committee under the Plan (which items may be delegated by the Board or the
Committee to the Plan Administrator). To the extent that Eligible Employees are

Administrator shall be applicable equally to all Eligible Employees.

terms, conditions, restrictions and limitations of Purchase Rights; provided,

administration. The Plan Administrator's interpretation of the Plan and its

SECTION 4.  STOCK SUBJECT TO PLAN

         Stock acquired by Participants under the Plan shall be drawn from
authorized and unissued Stock or shall be Stock acquired or caused to be
acquired by the Employer or the Company on behalf of the Participants, or a
combination of any of the foregoing, as determined from time to time at the sole
discretion of the Board. Subject to adjustment from time to time as provided in
Section 19, a maximum of 6,700,000 shares of Stock may be acquired under the
Plan; of such 6,700,000 shares of Stock, the maximum number of authorized but
unissued shares of Stock which shall be made available for sale under the Plan
shall be 3,350,000 shares of Stock. Any shares of Stock that have been made
subject to a Purchase Right that cease to be subject to the Purchase Right
(other than by reason of exercise of the Purchase Right), including, without
limitation, in connection with the cancellation or termination of the Purchase
Right, shall again be available for acquisition in connection with future grants
of Purchase Rights under the Plan.

SECTION 5. OFFERING DATES

         5.1      OFFERING PERIODS

         The Plan shall be implemented by one or more or a series of offerings
(each, an "Offering"), which need not be consecutive or at regular intervals.
Except as otherwise set forth herein, Offerings shall commence on July 1 and
January 1 of each year and end on the next December 31 and June 30,
respectively, occurring thereafter. Notwithstanding the foregoing, whether or
not Offerings are made, the date of commencement of the first Offering, the term
and frequency of Offerings and any time or interval between Offerings shall be
determined by the Board or the Committee. Without limiting the generality of the
foregoing, the Board or the Committee may establish (a) a different term for one
or more Offerings and (b) different commencing and ending dates for such
Offerings; provided, however, that an Offering Period (the "Offering Period")
may not exceed one year. Unless the Plan Administrator in the Plan
Administrator's sole discretion determines otherwise for future Offerings, an
employee who becomes eligible to participate in the Plan after an Offering
Period has commenced shall not be eligible to participate in such Offering but
may participate in any subsequent Offering, provided that such employee is still
an Eligible Employee as of the commencement of any such subsequent Offering.
Unless the Plan Administrator in the Plan Administrator's sole discretion
determines otherwise for future Offerings, Eligible Employees may not
participate in more than one Offering at a time. In the event the first or the
last day of an Offering Period is not a regular business day, then the first day
of the Offering Period shall be deemed to be the next regular business day and
the last day of the Offering Period shall be deemed to be the last preceding
regular business day.

         5.2      PURCHASE PERIODS

         Each Offering Period shall consist of one or more consecutive purchase
periods (each, a "Purchase Period"). Except as otherwise set forth below,
Purchase Periods shall commence on the first day of each month within the
Offering Period and end on the last day of each such month. Notwithstanding the
foregoing, the Board or the Committee may establish (a) different terms for one
or more Purchase Periods within an Offering Period and (b) different commencing
dates and Purchase Dates for any such Purchase Period. The last day of each
Purchase Period shall be the Purchase Date for such Purchase Period. In the
event the first or last day of a Purchase Period is not a regular business day,
then the first day of the Purchase Period shall be deemed to be the next regular
business day and the last day of the Purchase Period shall be deemed to be the
last preceding regular business day.

first Offering Date after satisfying the eligibility requirements and delivering
to the designated department or office of the Employer (the "Designated
Department") during the enrollment period established by the Plan Administrator
(the 





                                      -4-

<PAGE>   5


"Enrollment Period") a subscription (the "Subscription") in the form and
manner prescribed by the Plan Administrator and by the date established by the
Plan Administrator (the "Subscription Date"):

           (a)  indicating the Eligible Employee's election to participate in
                the Plan;

           (b)  authorizing payroll deductions and stating the amount to be
                deducted regularly from the Participant's pay; and

           (c)  authorizing the purchase of Stock for the Participant in each
                Purchase Period.

         An Eligible Employee who does not deliver a Subscription to the
Designated Department during the Enrollment Period and on or before the
Subscription Date shall not participate in the Plan for that Offering Period or
for any subsequent Offering Period, unless such Eligible Employee subsequently
enrolls in the Plan by delivering a Subscription to the Designated Department
during the Enrollment Period and on or before the Subscription Date for such
subsequent Offering Period. The Plan Administrator may, from time to time,
change the Subscription Date as deemed advisable by the Plan Administrator in
its sole discretion for the proper administration of the Plan.

         6.2      CONTINUED PARTICIPATION

         A Participant shall automatically participate in the next Offering
Period unless the Participant:

           (a)  delivers a Nonparticipation Notice to the Company pursuant to
                Section 6.3;

           (b)  stops payroll deductions pursuant to Section 9.2;

           (c)  withdraws from the Plan pursuant to Section 11.1; or

           (d)  terminates employment as provided in Section 12.

         6.3      PERCENTAGE DETERMINATIONS

         At least 10 business days prior to the commencement of each Offering
Period, the Company shall provide each Eligible Employee with written notice as
to the percentages determined by the Board (as contemplated by Section 8 and
Section 9.3) that are applicable to the next Offering Period (the "Percentage
Notice"). Each Participant is entitled to advise the Company in writing, within
the 10 business day period commencing on the date of the Percentage Notice, of
the Participant's decision to opt out of the Plan for such Offering Period by
delivering to the Company written notice indicating the Participant's decision
to opt out of the Plan for such Offering Period (the "Nonparticipation Notice").
Subject to Section 6.2, the Participant shall automatically participate in each
subsequent Offering Period unless the Participant so delivers the
Nonparticipation Notice with respect to the Percentage Notice applicable to any
such subsequent Offering Period.

SECTION 7.  LIMITATIONS ON RIGHT TO PURCHASE STOCK

         7.1      $25,000 LIMITATION

         No Participant shall be entitled to purchase Stock under the Plan (or
any other employee stock purchase plan that is intended to meet the requirements
of Code Section 423 sponsored by the Company, a Parent Corporation or a
Subsidiary Corporation) at a rate that exceeds U.S. $25,000 in fair market
value, determined as of the Offering Date for each Offering Period (or such
other limit as may be imposed by the Code), for each calendar year in which a
Participant participates in the Plan (or any other employee stock purchase plan
described in this Section 7.1).



                                      -5-


<PAGE>   6


         7.2      PRO RATA ALLOCATION

         In the event the number of shares of Stock that might be purchased by
all Participants in the Plan exceeds the number of shares of Stock available in
the Plan, the Plan Administrator shall make a pro rata allocation of the
remaining shares of Stock in as uniform a manner as shall be practicable and as
the Plan Administrator shall determine to be equitable. Fractional shares may be
issued under the Plan only to the extent permitted by the Board or the
Committee.

SECTION 8.  PURCHASE PRICE

         The purchase price (the "Purchase Price") at which Stock may be
acquired by Participants in an Offering pursuant to the exercise of all or any
portion of a Purchase Right granted under the Plan shall be a percentage
determined by the Board for the applicable Offering Period, such percentage to
be not less than 85% and not more than 100%, of the fair market value of the
Stock on the Purchase Date. The fair market value of the Stock on the Purchase
Date shall be (a) in the case of authorized but unissued shares of Stock, the
weighted average trading price for the Stock on The Toronto Stock Exchange for
the five trading days completed immediately prior to the Purchase Date, and (b)
in the case of shares of Stock purchased on the open market, the purchase price
of such Stock on The Toronto Stock Exchange on the Purchase Date. In the event
that such Stock is not listed and posted for trading on The Toronto Stock
Exchange on the date in question, then the fair market value shall be determined
based on the price(s) of the Stock on such stock exchange in Canada on which the
Stock is listed and posted for trading as may be selected for such purpose by
the Board. In the event that such Stock is not listed and posted for trading on
any stock exchange the fair market value shall be the fair market value of such
Stock as determined by the Board in good faith. For clarification, in the event
that Stock is acquired by Participants in any given Purchase Period from a
combination of both authorized but unissued Stock and Stock purchased on the
open market, then the "effective" Purchase Price shall be equal to the dollar
amount obtained by dividing (A) the sum obtained by adding (i) the product of
the number of shares of Stock issued from treasury and the applicable Purchase
Price and (ii) the product of the number of shares of Stock purchased on the
open market and the applicable Purchase Price, by (B) the total number of shares
of Stock acquired on the Purchase Date.

SECTION 9.  PAYMENT OF PURCHASE PRICE

         9.1      GENERAL RULES

         Stock that is acquired pursuant to the exercise of all or any portion
of a Purchase Right may be paid for only by means of payroll deductions from the
Participant's Eligible Compensation unless the Plan Administrator in the Plan
Administrator's sole discretion establishes other methods for payment of the
Purchase Price. Except as set forth in Section 6.3 or this Section 9, the amount
of compensation to be withheld from a Participant's Eligible Compensation during
each pay period shall be determined by the Participant's Subscription.

         9.2      CHANGE NOTICES

         During an Offering Period, a Participant may elect to stop, but not
otherwise decrease or increase, withholding from the Participant's compensation
by providing an amended Subscription to the Designated Department by a date at
least ten days prior to the end of the pay period for which such election is to
be effective (the "Change Notice Date"); provided, however, that the Plan
Administrator may change the Change Notice Date from time to time. In the event
a Participant elects to stop withholding during any Offering Period, the
Participant may not resume participation in the Plan during the same Offering
Period, but may participate in any subsequent Offering under the Plan by again
delivering a Subscription to the Designated Department in accordance with
Section 6.1.





                                      -6-

<PAGE>   7


         9.3      PERCENT WITHHELD

         The amount of payroll withholding with respect to the Plan for any
Participant during any pay period shall be at least 1% of the Participant's
Eligible Compensation for such pay period, but shall not exceed 10%, or such
lesser percentage as may be determined by the Board for the applicable Offering
Period, of the Participant's Eligible Compensation for such pay period. Amounts
shall be withheld only in whole percentages.

         9.4      PAYROLL DEDUCTIONS

         Payroll deductions shall commence on the first payday following the
Offering Date and shall continue through the last payday of the Offering Period
unless sooner altered or terminated as provided in the Plan.

         9.5      MEMORANDUM ACCOUNTS

         Individual accounts shall be maintained for each Participant for
memorandum purposes only. All payroll deductions from a Participant's
compensation shall be credited to such account, but shall be deposited with the
general funds of the Employer. All payroll deductions received or held by the
Employer may be used by the Employer for any corporate purpose.

         9.6      NO INTEREST

         No interest shall be paid on cash payments or payroll deductions
received or held by the Employer.

         9.7      ACQUISITION OF STOCK

         On each Purchase Date of an Offering Period, each Participant shall
automatically acquire, pursuant to the exercise of the Participant's Purchase
Right, the number of shares of Stock arrived at by dividing the total amount of
the Participant's accumulated payroll deductions for the Purchase Period by the
Purchase Price; provided, however, that in no event shall the number of shares
of Stock purchased by the Participant exceed the number of whole shares of Stock
so determined, except to the extent that the Board or the Committee has
determined that fractional shares may be issued under the Plan.

         9.8      REFUND OF EXCESS AMOUNTS

         Any cash balance remaining in the Participant's account after a
purchase of Stock at the end of a Purchase Period shall be refunded to the
Participant as soon as practical after the Purchase Date. In the event the cash
to be returned to a Participant pursuant to the preceding sentence is in an
amount less than the amount necessary to purchase a whole share of Stock, and
the Board or Committee has not determined that fractional shares may be issued,
the Plan Administrator may establish procedures whereby such cash is maintained
in the Participant's account and applied to the purchase of Stock in the
subsequent Purchase Period or Offering Period.

         9.9      WITHHOLDING OBLIGATIONS

         At the time the Purchase Right is exercised, in whole or in part, or at
the time some or all of the Stock is disposed of, the Participant shall make
adequate provision for federal, provincial and state withholding obligations of
the Employer, if any, that arise upon exercise of the Purchase Right or upon
disposition of the Stock. The Employer may, but shall not be obligated to,
withhold from the Participant's compensation the amount necessary to meet such
withholding obligations.

         9.10     TERMINATION OF PARTICIPATION

         No Stock shall be purchased on behalf of a Participant on a Purchase
Date if the Participant's participation in the Offering or the Plan has
terminated prior to such Purchase Date.

         9.11     PROCEDURAL MATTERS

         The Plan Administrator may, from time to time, establish (a)
limitations on the frequency and/or number of changes in the amount withheld
during the Offering, (b) an exchange ratio applicable to amounts withheld in a
currency other than U.S. dollars, (c) payroll withholding in excess of the
amount designated by a Participant in order to adjust for delays or mistakes in
the Employer's processing of properly completed withholding elections, and (d)
such other limitations or procedures as deemed advisable by the Plan
Administrator in the Plan Administrator's sole discretion that are consistent
with the Plan and in accordance with the requirements of Code Section 423.

         9.12     LEAVES OF ABSENCE

         During leaves of absence approved by the Employer and meeting the
requirements of the applicable Treasury Regulations promulgated under the Code,
a Participant may continue participation in the Plan by delivering cash payments
to the Plan Administrator or such individual designated by the Plan
Administrator on the Participant's normal paydays equal to the amount of the
Participant's payroll deduction under the Plan had the Participant not taken a
leave of absence.

SECTION 10.  STOCK PURCHASED UNDER THE PLAN

         10.1     ESPP BROKER

         If the Plan Administrator designates or approves a stock brokerage or
other financial services firm to hold shares purchased under the Plan for the
accounts of Participants (the "ESPP Broker"), the following procedures shall
apply. Promptly following each Purchase Date, the number of shares of Stock
purchased by each Participant shall be deposited into an account established in
the Participant's name with the ESPP Broker. A Participant shall be free to
undertake a disposition of the shares of Stock in the Participant's account at
any time, but, in the absence of such a disposition, the shares of Stock must
remain in the Participant's account at the ESPP Broker until the holding period
set forth in Code Section 423(a) has been satisfied. With respect to shares of
Stock for which the Code Section 423(a) holding periods have been satisfied, the
Participant may move those shares of Stock to another brokerage account of the
Participant's choosing or request that a stock certificate be issued and
delivered to the Participant. A Participant who is not subject to payment of
U.S. income taxes may move the Participant's shares of Stock to another
brokerage account of the Participant's choosing or request that a stock
certificate be delivered to the Participant at any time, without regard to the
Code Section 423(a) holding period.

         10.2     NOTICE OF DISPOSITION

         By entering the Plan, each Participant agrees to give the Employer
prompt notice of any Stock acquired in an Offering that is disposed of within
the later of (a) two years after the Offering Date for such Offering and (b) one
year after the Purchase Date for such Stock, showing the number of such shares
disposed of and the Purchase Date for such Stock. This notice shall be required
from the Participant regardless of whether or not the Participant is then
employed by the Employer. This notice shall not be required if and so long as
the Company or Employer has a designated ESPP Broker.

SECTION 11.  VOLUNTARY WITHDRAWAL

         11.1     WITHDRAWAL FROM THE PLAN

         A Participant may withdraw from the Plan by providing to the Designated
Department a notice of withdrawal in the form and manner required by the Plan
Administrator for such purpose. Any withdrawal from an Offering shall constitute
a withdrawal from the Plan unless the Board or the Committee determines for any
future Offerings that withdrawal from an Offering shall not result in a
withdrawal from the Plan and any succeeding Offering. Such notice of withdrawal
must be provided to the Designated Department at least ten days prior to the end
of the Purchase Period for which such withdrawal is to be effective or by any
other date specified by the Plan Administrator for any future Offering. If a
Participant withdraws after the Purchase Date for a Purchase Period of an
Offering, the withdrawal shall not affect Stock acquired by the Participant in
that Purchase Period and any earlier Purchase Periods. In the event a
Participant voluntarily elects to withdraw from the Plan, the withdrawing
Participant may not resume participation in the Plan during the same Offering
Period, but may participate in any subsequent Offering under the Plan by again
delivering a Subscription to the Designated Department in accordance with
Section 6.1.

         11.2     RETURN OF PAYROLL DEDUCTIONS

         Upon withdrawal from the Plan pursuant to Section 11.1, the withdrawing
Participant's accumulated payroll deductions that have not been applied to the
purchase of Stock shall be returned as soon as practical after the withdrawal,
without the payment of any interest, to the Participant, and the Participant's
interest in the Offering shall terminate. Such accumulated payroll deductions
may not be applied to any other Offering under the Plan.

SECTION 12.  TERMINATION OF EMPLOYMENT

         Termination of a Participant's employment with the Employer for any
reason, including retirement, disability or death, or the failure of a
Participant to remain an Eligible Employee, shall immediately terminate the
Participant's participation in the Plan. The payroll deductions credited to the
Participant's account since the last Purchase Date shall, as soon as practical,
be returned to the Participant or, in the case of a Participant's death, to the
Participant's legal representative, and all the Participant's rights under the
Plan shall terminate. Interest shall not be paid on sums returned to a
Participant pursuant to this Section 12. A transfer of employment or services
between or among the Company and a Designated Subsidiary shall not be considered
a termination of employment or services.

SECTION 13.  RESTRICTIONS UPON ASSIGNMENT

         A Purchase Right granted under the Plan shall not be transferable and
shall be exercisable during the Participant's lifetime only by the Participant.
The Plan Administrator will not recognize, and shall be under no duty to
recognize, any assignment or purported assignment by a Participant of the
Participant's interest in the Plan, of the Participant's Purchase Right or of
any rights under the Participant's Purchase Right.

SECTION 14.  NO RIGHTS OF SHAREHOLDER UNTIL SHARES ISSUED

With respect to shares of Stock subject to a Purchase Right, a Participant shall
not be deemed to be a shareholder of the Company, and the Participant shall not
have any of the rights or privileges of a shareholder. A Participant shall have
the rights and privileges of a shareholder of the Company when, but not until,
the shares have been issued following exercise of the Participant's Purchase
Right.

SECTION 15.  AMENDMENT OF THE PLAN

         The Board or the Committee may amend the Plan in such respects as it
shall deem advisable; provided, however, that to the extent required for
compliance with Code Section 423 or any applicable law or regulation,
shareholder approval will be required for any amendment that will (a) increase
the total number of shares as to which Purchase Rights may be granted under the
Plan, (b) modify the class of employees eligible to receive Purchase Rights, or
(c) otherwise require shareholder approval under any applicable law or
regulation.

SECTION 16.  TERMINATION OF THE PLAN

         The Board may suspend or terminate the Plan at any time. Unless the
Plan shall theretofore have been terminated by the Board, the Plan shall
terminate on, and no Purchase Rights shall be granted after June 30, 2008,
except that such termination shall have no effect on Purchase Rights granted
prior thereto. No Purchase Rights shall be granted during any period of
suspension of the Plan.

SECTION 17.  NO RIGHTS AS AN EMPLOYEE

         Nothing in the Plan shall be construed to give any person (including
any Eligible Employee or Participant) the right to remain in the employ of the
Company or a Parent Corporation or Subsidiary Corporation, or to affect the
right of the Company or a Parent Corporation or Subsidiary Corporation to
terminate the employment of any person (including any Eligible Employee or
Participant) at any time with or without cause.

SECTION 18.  EFFECT UPON OTHER PLANS

         The adoption of the Plan shall not affect any other compensation or
incentive plans in effect for the Company or any Parent Corporation or
Subsidiary Corporation. Nothing in the Plan shall be construed to limit the
right of the Company, any Parent Corporation or any Subsidiary Corporation to
(a) establish any other forms of incentives or compensation for employees of the
Company, any Parent Corporation or any Subsidiary Corporation or (b) grant or
assume options otherwise than under the Plan in connection with any proper
corporate purpose, including, but not by way of limitation, the grant or
assumption of options in connection with the acquisition, by purchase, lease,
merger, consolidation or otherwise, of the business, stock or assets of any
corporation, firm or association.

SECTION 19.  ADJUSTMENTS

         19.1     ADJUSTMENT OF SHARES

         In the event that, at any time or from time to time, a stock dividend,
stock split, spin-off, combination or exchange of shares, recapitalization,
merger, consolidation, distribution to shareholders other than a normal cash
dividend, or other change in the Company's corporate or capital structure
results in (a) the outstanding shares, or any securities exchanged therefor or
received in their place, being exchanged for a different number or class of
securities of the Company or of any other corporation or (b) new, different or
