                       INTRODUCTION AND 1998 HIGHLIGHTS

     Stillwater Mining Company mines, processes and refines palladium, platinum
and associated metals ("PGMs") from a geological formation in southern Montana
known as the J-M Reef.  The J-M Reef is the only significant source of platinum
group metals, or PGMs, outside South Africa and Russia.  Associated by-product
metals of PGMs include rhodium, gold, silver, nickel and copper.  The J-M Reef
is an extensive mineralized zone containing PGMs which have been traced over a
strike length of approximately 28 miles.   All of the company's current mining
operations are conducted at the Stillwater Mine in Nye, Montana.  Expansion is
under way at the Stillwater Mine and at the East Boulder project approximately
13 miles away toward the western end of the J-M Reef.

     PGMs are rare precious metals with unique physical properties that are used
in diverse industrial applications and in the jewelry industry.  The largest and
fastest growing use for PGMs is in the automotive industry for the production of
catalysts that reduce harmful automobile emissions.  Palladium is also used
extensively in the production of electronic components for personal computers,
cellular telephones, facsimile machines and other devices, as well as dental
applications.  Platinum's largest use is for jewelry.  Industrial uses for
platinum include the production of data storage disks, glass, paints, nitric
acid, anti-cancer drugs, fiber optic cables, fertilizers, unleaded and high-
octane gasolines and fuel cells.

     At December 31, 1998, the company had proven and probable reserves of
approximately 37.1 million tons of ore containing approximately 26.3 million
ounces of palladium and platinum in a ratio of approximately 3.3 parts palladium
to one part platinum.

Highlights of the 1998 year included:

 .    Production increased to 444,000 ounces of palladium and platinum in 1998
     from 355,000 ounces in 1997.

 .    Cash production costs per ounce decreased to $151 in 1998 from $174 in
     1997, and total production costs per ounce decreased to $178 in 1998 from
     $207 in 1997.

 .    Mill recovery rates improved to 91% in 1998 from 89% in 1997.

 .    Mechanized mining increased to 85% in 1998 from 80% in 1997, and tons
     mined increased to 720,000 in 1998 from 580,000 in 1997.

 .    Revenues increased to $106.7 million in 1998 compared to $76.9 million in
     1997, and the company reported net income of $13.4 million in 1998 compared
     to a net loss of $5.4 million in 1997. The improvement in profitability was
     achieved despite the adverse effect of hedging positions that resulted in
     realization of below market prices for palladium. The company's average
     realized price was $202 per ounce in 1998 compared to the average market
     price of $286 per ounce.

 .    In the fourth quarter, the company announced a plan (the "1998 Expansion
     Plan") designed to increase annual PGM production from its current level of
     approximately 450,000 ounces to an annualized rate of 1.2 million ounces by
     the end of 2001. The plan consists of an expansion of the existing
     Stillwater Mine from the current level of 2,000 tons of ore per day to
     3,000 tons of ore per day, the construction of a second mine approximately
     13 miles to the west of Nye, capable of processing at the rate of 2,000
     tons of ore per day, and the expansion of the existing smelter and base
     metals refinery. The total capital cost of the expansion program is
     estimated to be $385 million.

                                       3

 .    In order to minimize the downside price risk inherent in the palladium and
     platinum markets while retaining most of the potential to obtain higher
     prices, the company entered into long-term sales contracts with General
     Motors Corporation, Ford Motor Company, Mitsubishi Corporation and KEMET
     Corp. The contracts cover the company's production over the five-year
     period from January 1999 through December 2003. Under the contracts, the
     company has committed between 90% to 100% of its actual palladium
     production. Palladium sales are priced at a slight discount to market, with
     a floor price averaging approximately $225 per ounce. The company has
     agreed to an average maximum palladium price of approximately $400 per
     ounce on approximately 30% of its production. The remaining 70% of the
     company's palladium production is not subject to any price cap. In
     addition, the company has committed approximately 20% of its planned annual
     platinum production over the next five years. Platinum sales are priced at
     a slight discount to market, subject to an average minimum price of $350
     per ounce with an average maximum price of $425 per ounce. The remaining
     80% of the company's planned annual platinum production is not committed
     under these contracts. Such platinum production remains available for sale
     at prevailing market prices or under forward sales contracts.
 .
     The company developed a financing plan to provide the necessary capital for
     the 1998 Expansion Plan. On October 19, 1998, the company completed an
     offering of 2,000,000 common shares at a price of $30.75 per share (prior
     to the three for two stock split effected on December 31, 1998). In
     November 1998, the underwriters exercised an over allotment option for an
     additional 300,000 shares (pre-split). The company realized net proceeds of
     approximately $67 million from the offering. In addition, the company
     obtained a seven-year $175 million senior secured credit facility with a
     syndicate of banks led by The Bank of Nova Scotia (the "Scotiabank Credit
     Facility"). This credit facility provides for a $125 million term loan
     facility and a $50 million revolving credit facility. Proceeds of the term
     loan facility will be used to finance a portion of the 1998 Expansion Plan
     while proceeds of the revolving credit facility will be used for general
     corporate and working capital needs. The balance of the the expansion
     plan's capital cost is expected to be funded by operating cash flow.

 .    On December 8, 1998, the company declared a three-for-two stock split on
     the company's common stock effected in the form of a stock dividend paid on
     December 31, 1998 to shareholders of record on December 21, 1998.

and "--Risk Factors" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations".

                            HISTORY OF THE COMPANY

          Palladium and platinum were discovered in the J-M Reef by Johns
Manville Corporation geologists in the early 1970s. In 1979, a Manville
subsidiary entered into a partnership agreement with Chevron U.S.A. Inc. to
develop PGMs discovered in the J-M Reef. Manville and Chevron explored and
developed the Stillwater property and commenced underground mining in 1986.

          In 1992, the company was incorporated and on October 1, 1993, Chevron
and Manville transferred substantially all assets, liabilities and operations at
Stillwater to the company, with Chevron and Manville each receiving a 50%
ownership interest in the company's stock. In September 1994, the company
redeemed Chevron's entire 50% ownership. The company completed its initial
public offering in December 1994, and Manville sold a portion of its shares
through the offering reducing its ownership percentage to approximately 27%. In
August 1995, Manville sold its remaining ownership interest in the company to
institutional investors. The company's common stock is publicly traded on the
American Stock Exchange under the symbol "SWC."

                            GEOLOGY OF THE J-M REEF

     The J-M Reef is located in the Beartooth Mountains in southern Montana.  It
is situated along the northern edge of the Beartooth Plateau, which rises to
elevations of over 10,000 feet.  This plateau is deeply dissected by several
rivers and their tributaries including the Stillwater River, towards the eastern
end of the reef and the Boulder River, near the western end of the reef.  Both
of these rivers have eroded their valley floors resulting in deep valleys cut
into the gently undulating elevated plateau.

     Geologically, the J-M Reef is composed of an assemblage of basic and
ultrabasic rocks derived from a single, large, buried magma body emplaced an
estimated 2.7 billion years ago.  The molten rock was sufficiently fluid at the
time of emplacement to allow individual minerals to crystallize sequentially,
with the heavier, more basic, darker minerals crystallizing first, and sinking
towards the bottom, leaving the lighter, more siliceous light-colored minerals
to crystallize out later to produce bands of norite, gabbro and anorthosite
which can be traced across most of the strike length of the complex.  Over time
the original horizontal orientation of the reef was changed as the reef was
tilted at an angle of 50 to 90 degrees to the north.  The upper portion of the
reef was eroded away to produce the essentially lenticular-shaped exposure of
the reef evident today. The reef has been identified for 28 miles in an east-
southeasterly direction.

     The PGMs, which consist of palladium, platinum and a minor amount of
rhodium, are concentrated in one principal layer along with small amounts of
nickel, copper, silver and gold.  The J-M Reef appears to form a continuous
layer which is exposed from the highest ridges over 9,500 feet above sea level
to the deepest valleys almost a mile below the surface of the plateau. The
mineralized horizon has been demonstrated to have a vertical continuity
exceeding 6,000 feet.  Additionally, one exploration hole in the Stillwater
Valley, drilled in 1998, has confirmed the continuity of the reef to the 1,400
foot elevation can be reasonably inferred.  Geological and geophysical evidence
suggests that the J-M Reef extends downward beyond the limits of currently
available mining practice.  Geological mapping and gravity surveys also suggest
that the dip of the J-M Reef flattens gently and may extend 30 miles or more to
the north.

     The J-M Reef is similar to South Africa's Bushveld Complex which contains
the well-known platiniferous Merensky Reef which is currently mined in many
localities.  The in situ PGM grade of the J-M Reef is significantly higher than
that of the Merensky Reef and its economically recoverable portion is
significantly thicker, making the J-M Reef generally amenable to a wider variety
of gravity assisted, mechanized mining methods.  The Merensky Reef, however, has
a substantially longer known surface strike length compared to the strike length
of the J-M Reef.

                               PGM ORE RESERVES

     The following table sets forth the company's proven and probable palladium
and platinum ore reserves as of December 31, 1998 and 1997.  The reserves
reflected below are based on a cut-off grade in 1998 of 0.3 ounce and in 1997 of
0.4 ounce of palladium plus platinum per ton, and assume the following prices
for palladium and platinum of:  $225 and $350 per ounce, respectively in 1998
and $155 and $375, respectively in 1997.  Proven and probable reserves give
effect to an average mining dilution of 10% at zero grade based on actual mining
experience.

     The December 31, 1998 and 1997 ore reserves were reviewed by Behre Dolbear
& Company, Inc. ("Behre Dolbear"), independent consultants, who are experts in
mining, geology and ore reserve determination. The company has utilized Behre
Dolbear to carry out independent reviews and inventories of the company's ore
reserves since 1990.  The ore reserves have been affirmed and verified by Behre
Dolbear in alternating years prior to 1997.  See "Risk Factors - Reserve
Estimates."

  (1) Reserves are defined as that part of a mineral deposit that can be
      economically and legally extracted or produced at the time of
      determination and is customarily stated in terms of "ore" when dealing
      with metals. The probable reserves are computed from information similar
      to that used for proven reserves, but the sites for inspection, sampling
      and measurement are between 50 and 1,000 feet apart.  The degree of
      assurance, although lower than that for proven reserves, is sufficient to
      predict the geological regularity of the reef between points of
      observation.  See "-- Risk Factors" and "Management's Discussion and
      Analysis of Financial Condition and Results of Operations - Factors That
      May Affect Future Results and Financial Condition."

  (2) Total probable reserves include 13.3 million tons and 11.5 million tons at
      December 31, 1998 and 1997, respectively in the area of East Boulder.
      Significant capital investments will be required to access the East
      Boulder reserves. See "Current Operations -- East Boulder Project."

  (3) Expressed as palladium plus platinum ounces per ton at a ratio of 3.3
      parts palladium to one part platinum, before processing losses of
      approximately ten percent (10%).

       Reserves are consumed during mining operations and the company generally
  replaces reserves by drilling on a close-spaced pattern mineralized material
  which has been identified geologically but not yet established as proven and
  probable reserves.  Because of the expense of the close-spaced drilling
  necessary to generate proven mining reserve estimates, the company generally
  attempts to establish sufficient reserves to support its mine development
  objective of approximately 18 months of production.

                              CURRENT OPERATIONS

  STILLWATER MINE

       The company's current mining operations take place at the Stillwater
  Mine, an underground mine accessing the J-M Reef in Nye, Montana.  In
  addition, the company owns and maintains 110,000 square feet of buildings
  which contain the concentrator, shop and warehouse, changing facilities,
  headframe, hoist house, paste plant, storage facilities and office.  All
  structures are located within its 1,340 acre operating permit area at the
  Stillwater Mine. The Stillwater Mine is wholly owned and operated by the
  company. The mine is located approximately 85 miles southwest of Billings,
  Montana and is accessed by a paved road. The mine has adequate water and power
  from established sources.

  MINING

       The Stillwater Mine accesses a five-mile segment of the J-M Reef, between
  the elevations of 6,700 and 3,100 feet above sea level.  Deep exploration
  drill holes have confirmed the structure and mineralization of the J-M Reef
  down to an elevation of 1,400 feet.  The deposit appears to be open at depth
  and will be further verified by additional drilling.   Access to the ore at
  the Stillwater Mine is by means of a 1,950-foot vertical shaft and by
  horizontal adits and drifts driven parallel to the strike of the J-M Reef at
  vertical intervals of between 200 feet and 300 feet.  Adits have been driven
  from the surface in the Stillwater Valley at elevations of 5,000 feet above
  sea level or more.  Five drifts have been developed below the valley floor by
  ramping down from the 5,000-foot level to extract ore from the reef down to
  the 4,000-foot elevation.  Four major levels below the 5,000-foot level are
  now being developed from the shaft and shaft ramp system.

                                       6
<PAGE>
 
       The 1,950-foot vertical shaft, which was commenced in 1994 and
  commissioned in 1997 as part of the company's 1994 Expansion Plan to double
  output from 1,000 to 2,000 tons of ore per day, was sunk adjacent to the
  concentrator to increase efficiency of the operation.  All ore and waste are
  crushed before being hoisted up the shaft.  The production shaft and
  underground crushing station have reduced haulage times and costs, improved
  the material handling of ore and waste and improved the grinding capabilities
  of the concentrator. For the foreseeable future, ore from those areas above
  the 5,000-foot west elevation will continue to be hauled to the surface by
  train.  Ore from those areas below the 5,000-foot level and those that are not
  currently connected to the shaft are transported to the surface by 15-ton
  underground trucks.  The portion of waste that cannot be used for backfill in
  underground excavations is hauled to the surface or hoisted up the shaft,
  depending on its location, and used in the rock embankment of the tailings dam
  or is placed in the permitted waste disposal site.

       Prior to 1994, almost all of the company's mining activities utilized
  "cut-and-fill" stoping methods. This method extracts the ore body in ten-foot
  high horizontal cuts.  The open space created by the extraction of each cut is
  filled with waste rock and coarse concentrator tailings and becomes the floor
  for the next level of mining as the process moves upward.  Since 1994, the
  company has introduced two mechanized mining methods: "ramp-and-fill" and
  "sub-level stoping."  Ramp-and-fill is a mining method in which a succession
  of horizontal cuts are extracted from the ore body using mobile equipment.
  Access to the ore body is from ramps driven in or adjacent to the ore body
  allowing the use of hydraulic drills and load haul dump equipment.  Sub-level
  stoping is a mining method in which blocks of the reef approximately 50 feet
  high and up to 75 feet along strike are extracted in 30-foot intervals
  utilizing mobile electric hydraulic long-hole drills and remote control rubber
  tired load haul dump equipment.  The reef is mined in a retreat sequence along
  strike and mined out areas are filled with development waste.  The company
  believes that mechanized mining methods are safer, less expensive and more
  productive than traditional "cut-and-fill" stoping.  Mechanized mining
  increased from approximately 60% of tons mined in 1996 to approximately 80% in
  1997 and to approximately 85% in 1998.  Currently, direct costs per ton mined
  for mechanized stoping are approximately 39% less than cut-and-fill stoping
  and is nearly 100% more productive in terms of tons per man-hour. However, not
  all areas of the reef are amenable to mechanized methods, and the company will
  continue to select the appropriate mining method on a stope-by-stope basis.

  PRODUCTION

       During 1998, the company produced 444,000 ounces of palladium and
  platinum, up from 355,000 ounces in 1997 and 255,000 ounces in 1996.  See
  "Selected Financial and Operating Data."  In the fourth quarter of 1997, the
  company attained the 1994 Expansion Plan production goal by increasing
  production by 46% from approximately 1,370 tons of ore per day in the fourth
  quarter of 1996 to approximately 2,000 tons of ore per day during the fourth
  quarter of 1997.  In conjunction with the 1994 Expansion Plan, the company
  invested in new mobile mining equipment and developed a computerized scheduled
  maintenance system.  In addition, the rate of underground development
  increased on both existing levels as well as new levels accessed from the
  shaft.  Additional surface facilities were also constructed, including a new
  maintenance shop and warehouse and an extension of the site offices and change
  house.  Site services were expanded and upgraded and appropriate investment in
  infrastructure was made to accommodate future plans.  The company reduced its
  cash production costs from $184 per ounce in 1996 to $174 per ounce in 1997,
  and to $151 per ounce in 1998.

       During 1994 through 1997, the company's total capital expenditures for
 the expansion of the Stillwater Mine and facilities were approximately $70
 million, excluding capital costs for sustaining and rehabilitating the existing
 mine.

       During 1998, the company announced the 1998 Expansion Plan designed to,
  among other things, increase the Stillwater Mine production rate to 3,000 tons
  of ore per day and begin mining at East Boulder. The capital expenditure
  budget for the 1998 Expansion Plan relating to the Stillwater Mine is
  approximately $75 million.  See "--Future Expansion".

  CONCENTRATION

       The company maintains a concentrator plant adjacent to the Stillwater
  Mine.  Ore is defined as material with a metals content of 0.3 ounce per ton
  or more.  Ore is fed into the concentrator, mixed with water and ground to a
  slurry in a mill circuit to liberate the PGM-bearing sulfide minerals from the
  rock matrix. Various reagents are added to the slurry to separate the valuable
  sulfides from the waste rock in a flotation circuit.  In this circuit, the
  sulfide minerals are floated, recycled, reground and refloated to produce a
  concentrate suitable for further processing.  The flotation concentrate, which
  represents approximately 1% of the original ore weight, is filtered, dried and
  transported in trailers approximately 46 miles to the company's metallurgical
  complex in Columbus, Montana.  Approximately 60% of the material discarded
  from this process is used for backfill in the mine, with the balance stored in
  an onsite tailings containment area.

       As part of the 1994 Expansion Plan, the capacity of the concentrator was
  expanded with the addition of a large ball mill grinding unit, additional
  flotation capacity and ancillary equipment.  During 1998, the concentrator's
  crushing, grinding and flotation capacity were expanded to enable the
  processing of 3,000 tons of ore per day.

       During 1998, the company continued to improve the recovery performance of
  the flotation circuit installed in 1997.  Mill recovery improved to 91% for
  1998 compared to 89% for 1997 and 86% for 1996.

       In 1998, the company received an amendment to its existing Operating
  Permit which provides for the construction of a lined tailings impoundment
  that will serve the Stillwater Mine for the next thirty years.  In addition,
  the amendment removed the production limitation of 2,000 tons of ore per day
  at the Nye operation. An environmental group has filed a complaint challenging
  the amendment to the permit.  The company believes the compliant is without
  merit.  See "Regulatory and Environmental Matters".

  METALLURGICAL COMPLEX

       Smelting.  The company's metallurgical complex is located in Columbus,
       ---------                                                             
  Montana and consists of the precious metals smelter and base metals refinery.
  Concentrate from the mine site is fed to a 1.5 megawatt electric furnace,
  where it is melted and separated into a silica oxide rich slag and a PGM rich
  matte.

       The matte is tapped from the furnace and granulated.  The granulated
  furnace matte is remelted in one of two top blown rotary converters, which
  separate iron from the converter matte.  The converter matte is poured from
  the top blown rotary converter, granulated and transferred to the base metals
  refinery in two ton bags for further processing.  The granulated converter
  matte, approximately 10% of the original smelter feed weight, is primarily
  copper and nickel sulfides containing about 2% PGMs.

       The gasses released from the smelting operations are routed through a
  gas/liquid scrubbing system, which removes approximately 99.8% of the sulfur
  dioxide.  Spent scrubbing solution is treated in a process that converts the
  sulfur dioxide to gypsum, or calcium sulfate, and regenerates clean scrubbing
  solution.  The gypsum is used by local farmers as a soil amendment.

       The initial expansion of the smelter was completed in 1997, increasing
  the daily smelting capacity from 22 tons of ore per day to 32 tons of ore per
  day.  Feed and power control systems for the existing furnace were modified, a
  second top blown rotary converter was added and the gas handling and solution
  regeneration systems were upgraded.  Additionally during 1997, the furnace was
  rebricked, a 30-day process that occurs every two to three years.  The furnace
  modifications resulted in significant power savings due to increased
  efficiency.  At 2,000 tons of ore per day of mine production, the smelter
  processes approximately 25-30 tons of concentrate per day.


                                       8
<PAGE>
 
     As part of the 1998 Expansion Plan, the smelter is being expanded to treat
the increased concentrate from the Stillwater Mine and the East Boulder project.
The expansion consists of the addition of a second furnace capable of treating
100 tons of concentrate per day and additional top blown rotary converter and
ancillary facilities. The expansion is expected to be complete in the second
half of 1999 and is expected to cost approximately $32 million.

     Base Metals Refinery. In 1996, the company constructed and commissioned the
     --------------------
base metals refinery, which utilizes the patented Sherritt Process, whereby
sulfuric acid is used to dissolve the nickel, copper, cobalt and iron from the
converter matte. This process upgrades the converter matte product over 25 to 30
times (from 2% PGMs to 55-60% PGMs). The base metals refinery has a capacity
equivalent to more than 4,000 tons of ore per day of mine production. The
present plant is operated two shifts per day, five days per week. Even though
mine production ramped up during 1997 and 1998, the base metals refinery was
able to increase efficiencies and maintain a five-day schedule.

     The iron is precipitated out of the solution and returned to the smelter to
be processed and removed in the slag. The dissolved nickel, copper and cobalt is
shipped via truck, as a sulfate solution, to an outside refiner located in
Canada. The company is paid for a portion of the nickel and cobalt content of
the solution. In the second half of 1998, the company began construction of the
first stage of a copper/nickel refinery. This new electrowinning circuit is
scheduled for completion in the first quarter of 1999. During 1999, the second
stage of the copper/nickel circuit will be constructed as part of the expansion
of the base metals refinery. The total cost of the nickel/copper refinery is
expected to be approximately $8.5 million.

     The resulting PGM rich filter cake is shipped via air freight to three
different refineries and is returned to the account of the company as 99.95% PGM
sponge after approximately 22-35 days. The company pays its refiners a refining
charge in United States dollars per ounce for the toll processing of the base
metals refinery filter cake.

     The 1998 Expansion for the base metals refinery contemplates an additional
autoclave and an upgrade to the piping and ventricular systems required to
handle the additional material anticipated as a result of the Nye and East
Boulder expansions. The base metals refiner expansion is expected to be
completed in the second half of 1999.

SECONDARY MATERIALS PROCESSING

     A sampling facility for secondary materials was completed in late 1997. The
facility was designed to accept spent catalysts that can be crushed and added to
the electric furnace. Several test lots were processed during 1997, and it was
determined that the spent auto catalysts are suitable for processing at the
company's facilities. During 1998, the company began processing small shipments
of spent auto catalysts and in 1998 processed approximately 139 tons of spent
catalysts.

EXPLORATION ACTIVITIES

     Major portions of the J-M Reef have yet to be exposed to drilling and
development sufficient to allow for the delineation of additional reserves.
However, given the magnitude of its current proven and probable reserves, the
company's exploration activities are limited. The company's current plans are to
continue to focus on its current PGM reserves and mineralization of the J-M Reef
rather than exploring for or attempting to acquire additional developed or
undeveloped ore reserves. Consequently, exploration does not represent a
significant expenditure for the company.

EAST BOULDER PROJECT

     The East Boulder project will provide western access to the J-M Reef, Sweet
Grass County, Montana. The East Boulder property is wholly-owned by the company.
Development will consist of construction of mine and support facilities,
including an underground crusher, a surface concentrator and 

                                       9
<PAGE>
 
ancillary surface facilities. These facilities have been designed to allow
expansion beyond 2,000 tons of ore per day should this be economically justified
and if existing operating permits are amended. In 1996, the company began work
on the development phase of the East Boulder project, but suspended all work
other than permitting late in 1996.

     In November 1997, with the completion of the 1994 Expansion Plan and higher
prices for palladium and platinum, the company announced plans to restart the
East Boulder project. During the second quarter of 1998, the company accepted
delivery of a tunnel boring machine and commenced to drive the 18,500-foot long,
15-foot diameter tunnel. This is expected to take approximately 12 to 18 months
and cost approximately $14 million. During 1998, the company acquired and
refurbished a second tunnel boring machine which is expected to commence
drilling a second tunnel in the first quarter of 1999. Additional activities
commenced during the year consisted of conceptual engineering, sitework and
construction of support facilities.

     During 1999, the company expects to continue underground development,
detailed engineering and construction of the concentrator and ancillary
facilities at East Boulder. The East Boulder mine is expected to begin
commercial production in the second half of 2001. The estimated total cost of
the project is $270 million.

OTHER PROPERTIES

     In Columbus, Montana, the company owns and maintains a 23,200 square foot
smelter plant and a 17,000 square foot base metals refinery. Neither of these
properties is currently subject to any mortgage or other encumbrance. The
company also leases a 10,100 square foot office building in Columbus. The
company believes that its existing facilities are adequate to service current
production levels. The company also owns additional parcels of land totaling
approximately 2,890 acres in Stillwater County, Montana and additional property
in Big Timber, Montana which will be used to provide employee housing. Certain
of these parcels are leased to ranch operators, and one has been subdivided for
the lease or sale of residential lots. About 60 acres of one property is within
the company's operating permit boundaries. Some of these properties also include
residential rental units. Non-mining properties are subject to a mortgage in
favor of Chevron and Manville to support the company's indemnification
obligations to such parties.

SALES AND HEDGING ACTIVITIES

     Palladium, platinum, rhodium and gold are sold to a number of consumers and
dealers with whom the company has established trading relationships. Refined
PGMs of 99.95% purity in sponge form are transferred upon sale from the
company's account at third party refineries to the account of the purchaser. By-
product metals are purchased at market price by customers, brokers or outside
refiners.

     During 1998, the company implemented a marketing strategy designed to
minimize the downside price risk inherent in the palladium and platinum markets
while retaining most of the potential to obtain higher prices.  The company
entered into long-term sales contracts with General Motors Corporation, Ford
Motor Company, Mitsubishi Corporation and KEMET Corp. The contracts cover the
company's production over the five-year period from January 1999 through
December 2003. Under the contracts, the company has committed between 90% to
100% of its actual palladium production. Palladium sales are priced at a slight
discount to market, with a floor price averaging approximately $225 per ounce.
The company has agreed to an average maximum palladium price of approximately
$400 per ounce on approximately 30% of its production. The remaining 70% of the
company's palladium production is not subject to any price cap. In addition, the
company has committed approximately 20% of its planned annual platinum
production over the next five years. Platinum sales are priced at a slight
discount to market, subject to an average minimum price of $350 per ounce with
an average maximum price of $425 per ounce. The remaining 80% of the company's
planned annual platinum production is not committed under these contracts. Such
platinum production remains available for sale at prevailing market prices or
under future contracts. The marketing contracts contain termination provisions
that allow the purchasers to terminate in the event the company breaches and the
breach is not cured within periods ranging from ten to thirty days of notice by
the purchaser. In addition, the contracts contain force majeure provisions that
allow for the suspension and, in one instance, the termination of the 

                                       10
<PAGE>
 
contract upon the occurrence of an event of force majeure. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

     The company has historically entered into hedging instruments from time to
time to manage the effect of price changes in palladium and platinum on the
company's cash flow. Prior to 1998, hedging activities typically consisted of
"spot deferred contracts" for future deliveries of specific quantities of PGMs
at specific prices, the sale of call options and the purchase of put options.
During the first quarter of 1997, the company entered into significant hedging
positions, particularly in palladium, for both 1997 and 1998 sales. Following a
sharp rise in palladium spot prices, the company's deliveries against these
hedge contracts throughout 1997 and 1998 resulted in substantial hedging losses.
These losses totaled approximately $10.2 million in 1997 and $26.8 million in
1998. At December 31, 1998, the company had fulfilled all of its below market
hedge contracts.

     From time to time, the company may enter into short-term delivery
contracts. At December 31, 1998, the company had 9,550 ounces of December
palladium production committed for delivery in January 1999 at an average price
of $284 per ounce, 13,100 ounces of platinum sold forward for delivery in 1999
at an average price of $375 per ounce. The company has credit agreements with
its major trading partners that provide for margin deposits in the event that
forward prices for palladium and platinum exceed the company's hedge contract
prices and their credit lines.

TITLE AND ROYALTIES

     The company holds 995 patented and unpatented lode or millsite claims
covering approximately 16,000 acres of the J-M Reef. The company believes that
approximately 130 of these claims cover 100% of the known apex of the J-M Reef.
Applications for patents covering 172 of the unpatented claims, for a total area
of 2,876.9 acres, have been submitted. Patents to 34 claims covering an area of
574.8 acres have been granted; 138 claims covering 2,302.1 acres have had first
half final certificates issued. The company is currently working with the USFS
to ensure the proper allocation of personnel and other resources required for
the USFS to complete the mineral examination process (the process by which a
determination is made as to whether a discovery of valuable minerals exists) on
the 138 claims which have first half final certificates issued. The company
expects that this process will take another year or more to complete. The patent
applications and the 138 claims covered thereby will then undergo several levels
of review within the U.S. Department of the Interior before submission to the
Secretary for signature. There can be no guarantee as to whether packets will
ever be issued for the 138 claims currently being processed. Another company
claim leased from the Mouat family and acquired through the agreement with
Anaconda Minerals Inc. was patented many years ago. The remaining claims either
adjoin the apex of the J-M Reef or provide sites for surface operations.

     Unpatented mining claims may be located on U.S. federal public lands open
to appropriation, and are generally considered to be subject to greater title
risk than other real property interests because the validity of unpatented
mining claims is often uncertain and is always subject to challenges of third
parties or contests by the federal government. The validity of an unpatented
mining claim or millsite, in terms of location and maintenance, depends on
strict compliance with a complex body of federal and state statutory and
decisional law and (as to unpatented mining claims) the existence of a discovery
of valuable minerals. In addition, there are few public records that
definitively control the issues of validity and ownership of unpatented mining
claims and millsites.

     Of the company's 995 controlled claims, 869 are subject to royalties,
including 711 subject to a 5% net smelter royalty payable to Franco Nevada
Mining Corporation, Limited, 56 subject to a 0.35% net smelter royalty payable
to the Mouat family, and 102 subject to both royalties. During 1998, the company
paid royalties of approximately $3.3 million.

SAFETY

     Current mine operations extend over five miles horizontally along the
Stillwater Complex and involve the use of heavy machinery and drilling and
blasting in confined spaces. The company's safety performance has shown
continued improvement in terms of its Lost Time Accident Rate ("LTA rate"). The
company's LTA rate in 1992 was 12.9 and has decreased steadily to a low of 2.3
in 1998. In order to continue this favorable trend, management has implemented
additional safety training programs and has vigorously applied the "Neil George
Five-Point Safety System," which is well known to the underground hard rock
mining industry. This program encourages daily interaction between employees and
supervisors with a specific focus on safety and requires subsequent
documentation of that interaction. Management believes that continued reductions
in accident frequency are achievable.

     Safety is a primary concern of the company, and the company believes that
training is a key element in accident prevention. Eighty hours of safety
training are required before inexperienced employees may start working
underground, and yearly retraining in first aid, accident prevention techniques
and equipment handling are mandatory for each mining employee.

     The metallurgical complex in Columbus, Montana maintained an exemplary
safety record in 1998 with zero lost time accidents and once again was the
recipient of the Governor's Safety and Health Achievement Award. The complex is
the first ever two-time recipient of this Award. The smelter (for the sixth
consecutive year) and the base metals refinery (for the second consecutive year)
were granted the Sharp's Award, which exempts these facilities from routine
Occupational Safety and Health Administration inspections.

EMPLOYEES

     As of December 31, 1998, the company had 899 employees in the following
areas:

</TABLE>

     Prior to 1995, the company's employees were non-union. In an election held
in July 1995, 50.6% of those voting favored the appointment of the Oil, Chemical
and Atomic Workers Union ("OCAW") as exclusive bargaining representative for
substantially all hourly workers. The union was certified by the National Labor
Relations Board in January 1996. On June 30, 1996, members of Local 2-1 of the
OCAW ratified their first contract agreement with the company, which became
effective on July 1, 1996. The contract has a term of three years and provides
for a cumulative increase in wages and benefits of 5.86% over the contract term.
This contract was negotiated using an interest-based bargaining approach that
has resulted in cooperative and stable labor relations. Management believes its
employee relations are good and believes its wages, benefits and working
conditions are competitive with other mining operations. The OCAW contract
expires in June 1999 and the company expects to begin negotiation of a new
contract during 1999.

     The company competes for individuals skilled in underground hard rock
mining techniques. Although the company has historically experienced a shortage
of qualified miners, the economic downturn affecting gold and base metal mining
has recently made available a significant number of skilled underground miners.
In addition, the company has instituted a training program to bring new
employees up to the status of 

                                       12
<PAGE>
 
qualified, experienced underground miners bringing the total number of miners at
the end of 1998 to 303. During 1998, the company hired 128 experienced
underground miners. The company will continue to recruit miners to meet the
demands of the company's increased production goals.

REGULATORY AND ENVIRONMENTAL MATTERS

     General.  The company's business is subject to extensive federal, state and
     -------
local government controls and regulations, including regulation of mining and
exploration which could involve the discharge of materials and contaminants into
the environment, disturbance of land, reclamation of disturbed lands, associated
potential impacts to threatened or endangered species and other environmental
concerns. In particular, statutes including, but not limited to, the Clean Air
Act, the Clean Water Act, the Solid Waste Disposal Act, the Emergency Planning
and Community Right-to-Know Act, the Endangered Species Act and the National
Environmental Policy Act, impose permit requirements, effluent standards, air
emission standards, waste handling and disposal restrictions and other design
and operational requirements, as well as recordkeeping and reporting
requirements, upon various aspects of mineral exploration, extraction and
processing. In addition, the company's existing mining operations may become
subject to additional environmental control and mitigation requirements if
applicable federal, state and local laws and regulations governing environmental
protection, land use and species protection are amended or become more stringent
in the future. For example, effective July 1, 1998 for the 1998 calendar year,
the company was required for the first time to annually report the volume of its
release of certain materials into the environment, including such constituents
that are placed within engineered tailings impoundments. Such reporting is
required by the Emergency Planning and Community Right-to-Know Act, noted above.
Additionally, the company is aware that federal regulation under the Solid Waste
Disposal Act governing the manner in which secondary materials and by-products
of mineral extraction and benefication are handled, stored and reclaimed or
reused are pending final revision which could affect the company's facility
design, operations, and permitting requirements.

     The company's past and future activities may also cause it to be subject to
liabilities under provisions of the Comprehensive Environmental Response,
Compensation and Liability Act of 1980, as amended ("CERCLA"), and analogous
state law. Such laws impose strict liability on certain categories of
potentially responsible parties including current property owners for releases
or threatened releases of hazardous substances into the environment which cause
the incurrence of cleanup costs.

     Generally, compliance with the above statutes requires the company to
obtain permits issued by federal, state and local regulatory agencies and to
file various reports and keep records of its operations affecting the
environment. Certain permits require periodic renewal or review of their
conditions. The company cannot predict whether it will be able to renew such
permits or whether material changes in permit conditions will be imposed. Non-
renewal of permits or the imposition of additional conditions could have a
material adverse effect on the company's financial condition and results of
operations.

     The company believes that its operations and facilities comply in all
material respects with current federal, state and local permits and regulations.
However, compliance with existing and future laws and regulations may require
additional control measures and expenditures which cannot be estimated at this
time. Compliance requirements for new mines and mills may require substantial
additional control measures that could materially affect permitting and proposed
construction schedules for such facilities. Under certain circumstances,
facility construction may be delayed pending regulatory approval. The cost of
complying with future laws and regulations may render currently operating or
future properties less profitable and could adversely affect the level of the
company's reserves and, in the worst case, render its mining operations
uneconomic.

     The company has agreed to indemnify each of Chevron and Manville for all

     Permitting and Reclamation.  Operating Permit 00118 issued by the Montana
     --------------------------                                               
Department of State Lands encompasses approximately 2,450 acres at the company's
Stillwater Mine located in Stillwater County, 

                                       13

Montana. The permit delineates lands that may be subject to surface disturbance.
At present, approximately 150 acres have been disturbed, 69 of which are
occupied by the tailings impoundment. The remaining acreage consists of
buildings, roads and portal sites. The company employs concurrent reclamation
wherever feasible.

     Reclamation regulations affecting the company's operations are promulgated
and enforced by the Hard Rock Bureau of the Montana Department of Environmental
Quality. Additional reclamation requirements may be imposed by the USFS during
the permitting process. For regulatory purposes, reclamation does not mean
restoring the land to its pre-mining state. Rather, it is returning the post-
mining land to a state which has stability and utility comparable to pre-mining
conditions. Reclamation concerns include stabilization and vegetation of
disturbed lands, controlling drainage from portals and waste rock dumps, removal
of roads and structures, neutralization or removal of process solutions and
visual aesthetics. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations-Environmental Obligations."

     Permits governing air and water quality are issued to the company by the
Montana DEQ, which has been delegated such authority by the federal government.
Operating permits issued to the company by the Montana DEQ and the USFS do not
have an expiration date but are subject to periodic reviews. The reviews
evaluate bonding levels, monitor reclamation progress, and assess compliance
with all permit requirements and mitigation measures.

     In April 1996, the company submitted a permit amendment application for the
expansion of the Stillwater Mine. This expansion proposal includes selection and
construction of a new tailings impoundment and removal of the arbitrary 2,000
tons of ore per day production cap. During 1997, as a result of this
application, the Montana DEQ began preparation of an Environmental Impact
Statement in order to assess the environmental impacts of the amendment. The
Montana DEQ issued the final Environmental Impact Statement in 1998, subsequent
to review of draft issuances and a public hearing. In November 1998, the Record
of Decision was issued by the Montana DEQ and the USFS. There were no material
changes from the original application.

     In the first quarter of 1999, an environmental group filed a complaint
against the Montana DEQ challenging the adequacy of the Environmental Impact
Statement and reclamation provisions developed in connection with the amendment
to the permit. The company is not named in the complaint. The complaint has not
been served and it is difficult to predict whether or how it may by pursued. The
company believes the suit is without merit.

     Capital outlay for the proposed long term tailings site is estimated to be
approximately $22 million. The current tailings facility, located adjacent to
the Stillwater Mine, has an expected life through the year 2003, assuming 2,000
tons of ore per day of mine production. A pipeline will connect the current and
proposed tailings impoundments.

     The East Boulder project is permitted with all necessary environmental
permits, including an operating permit to produce 2,000 tons of ore per day. The
water quality discharge permit for the East Boulder mine is in the renewal
process, during which time the formerly-issued permit remains in effect.


                              1998 EXPANSION PLAN

     During the third quarter of 1998, the company announced a new expansion
plan with a long-term goal of reaching an annualized rate of PGM production of
approximately 1.2 million ounces before year end 2001 (the "1998 Expansion
Plan"). The key components of the 1998 Expansion Plan include increasing mine
production at the Stillwater Mine from 2,000 to 3,000 tons of ore per day,
construction of a tailings facility, developing a new mine at East Boulder with
a permitted capacity of 2,000 tons of ore per day, and expansion of the smelter
and base metals refinery to accommodate the increased throughput.

                                       14
<PAGE>
 
     The company has completed a preliminary study setting forth the expected
costs and timetable for the 1998 Expansion Plan. Based upon studies by
independent mining engineers and our internal analyses, it is currently
estimated that the 1998 Expansion Plan will require capital investment of
approximately $385 million, as set forth below.

     Expansion at the Stillwater Mine. In the second quarter of 1998, H.A.
     --------------------------------
Simons Ltd., independent mining engineers, completed an engineering study on the
expansion of the Stillwater Mine. Based upon the engineering study and the
company's internal analyses, the expansion is estimated to cost approximately
$75 million and consists of modifications to the existing concentrator,
additional underground development and completion of a new tailings disposal
facility. During 1998, the concentrator expansion was completed and the
remaining expansion is expected to be completed by the end of 2001. When this
expansion is complete, it is expected that the Stillwater Mine will produce
approximately 725,000 to 750,000 ounces of PGMs annually.

     Development of East Boulder. The East Boulder site will provide western
     ---------------------------
access to the J-M Reef. The company has received all major permits necessary to
construct and operate a mining facility at East Boulder at a capacity of 2,000
tons of ore per day. Development at East Boulder will consist of construction of
mine and support facilities, including an underground crusher, a surface
concentrator and ancillary surface facilities. These facilities have been
designed, however, to allow expansion beyond 2,000 tons of ore per day should
this be economically justified and if existing operating permits are amended.

     In 1996, the company began work on the initial development phase of East
Boulder and invested $7.8 million, primarily for construction of a tunnel boring
machine and for electrical power supply to the mine portal site. The project was
suspended in October 1996, primarily due to a downturn in palladium and platinum
prices. However, the company continued to conduct permitting and environmental
activities at East Boulder, spending $1.1 million during 1997. In November 1997,
with the completion of the 1994 Expansion Plan and higher prices for palladium
and platinum, the company restarted the East Boulder project.

     During 1998, the company completed the tunnel boring machine and began
development work. Independent contractors have commenced work with the company
to drive a 18,500-foot long, 15-foot diameter tunnel to reach the J-M Reef. The
tunnel boring is expected to take between 12 and 18 months and as of February
28, 1999, the company has drilled approximately 8,200 feet. Based upon an
independent engineering study by Kilborn International Inc. (which covered
primarily the underground mine and mine-related infrastructure) and internal
analyses, the company estimates the development of East Boulder should cost
approximately $270 million. The company believes that the operating costs at
East Boulder should be substantially similar to the costs at the existing
operations at the Stillwater Mine. When completed, annual PGM production from
East Boulder is expected to be approximately 450,000 to 500,000 ounces. The key
risks associated with the development of the East Boulder mine are discussed
under the headings "Risk Factors--Expansion Plan Risks" and "--Government
Regulations and Permitting."

     Expansion of the Smelter and Base Metals Refinery. The company processes
     -------------------------------------------------              
concentrate produced from the Stillwater Mine at a smelter and a base metals
refinery located in Columbus, Montana. The company must expand these facilities
in order to accommodate the increased production expected from the Stillwater
Mine and the development of East Boulder. Based upon independent engineering
estimates and the company's internal analyses, the estimated capital cost of
expanding the smelter and the base metals refinery is approximately $40 million.

                  COMPETITION: PALLADIUM AND PLATINUM MARKET

     THE FOLLOWING DESCRIPTION OF RECENT EVENTS RELATING TO THE PALLADIUM AND
PLATINUM MARKETS IS NOT INTENDED TO BE COMPLETE, AND READERS ARE ADVISED TO
OBTAIN THEIR OWN INFORMATION AND ADVICE REGARDING THE COMMODITIES MARKETS.

GENERAL

     Palladium and platinum are rare precious metals with unique physical
qualities that are used in diverse industrial applications and in the jewelry
industry. The company knows of no economically viable replacements for PGMs in a
number of key technological and industrial applications. The development of a
less expensive alternative alloy or synthetic material which has the same
characteristics as PGMs could have a material adverse effect on the company's
revenues. Although the company is unaware of any such alloy or material, there
can be no assurance that none will be developed.

     The company competes with other suppliers of PGMs, some of which are
significantly larger than the company and have access to greater mineral
reserves and financial and commercial resources. See "Supply" below. In
addition, new mines may open over the next several years, increasing supply.
Furthermore, in certain industrialized countries, an industry has developed for
the recovery of PGMs from scrap sources, mostly from spent automotive and
industrial catalysts. There can be no assurance that the company will be
successful in competing with these existing and emerging PGM producers. See "--
Risk Factors" and "Management's Discussion and Analysis of Financial Condition
and Results of Operations."

DEMAND

     Demand for both palladium and platinum has increased since 1992, but the
increased demand for palladium has been much more dramatic. Demand for palladium
has grown from 3.9 million ounces in 1992 to 8.2 million ounces in 1998 - more
than double in six years. Platinum demand has increased from 3.8 million ounces
in 1992 to 5.1 million ounces in 1998 - a 34% increase.

     PGM's unique physical qualities include: (i) a high melting point; (ii)
superior conductivity and ductility; (iii) a high level of resistance to
corrosion; (iv) strength and durability; and (v) strong catalytic properties.
Palladium, like platinum, has numerous industrial applications and when combined
with silver, provides an extremely conductive material.

     The largest and fastest growing application for palladium is in the
automotive industry, which represented nearly 51% of the palladium demand for
1998. Demand for palladium in the next several years is projected to increase
significantly, driven primarily by its use in the production of automotive
catalysts which reduce harmful automobile emissions. In the U.S., the automobile
industry has made the decision to comply with standards that will decrease
automotive emissions to National Low Emission Vehicle standards beginning with
the 1999 model year vehicles. Europe and Japan have adopted more stringent
standards for the future as well. With growing concern for cleaner air, it is
expected that concern over automobile emissions will continue to spread. This
could have a marked effect on palladium usage and to an undetermined extent,
platinum.

     Approximately 30% of the palladium supply is consumed in the production of
electronic components for personal computers, cellular telephones, facsimile
machines and other devices. There are also indications that demand from the
electronic and semiconductor industries will continue to be strong, although
substitution of base metals for lower end applications continue to move forward.
Dentistry has also been a major use for palladium due to the substitution of
palladium alloys for gold-based dental alloys, representing approximately 15% of
the palladium demand for 1998.

                                       16
<PAGE>
 
          Approximately 60% of current world platinum production is used for
     industrial and manufacturing processes, most significantly for the
     manufacture of catalytic converters for the global auto industry.  In
     addition to catalytic converters, industrial uses of platinum include the
     production of data storage disks, glass, paints, nitric acid, anti-cancer
     drugs, fiber optic cables, fertilizers, unleaded and high octane gasolines
     and fuel cells.  The balance of current platinum demand is for the
     production of jewelry, such as gem settings for rings, and for
     investment/collector coins.  Supply and demand for platinum are essentially
     in balance.

     SUPPLY

          The primary production sources of palladium and platinum are mines
     located in the Republic of South Africa, which industry sources believe
     provided approximately 25% of the palladium and 74% of the platinum
     worldwide during 1998.  The principal PGM mining companies in the Republic
     of South Africa are Anglo American Platinum Corporation, Ltd., Impala
     Platinum Holdings, Ltd. and Western Platinum, Ltd.

          The second largest source of palladium and platinum is Russia, which
     industry sources believe provided approximately 64% of the palladium and
     approximately 17% of the platinum worldwide in 1998. Approximately half of
     this supply is believed to have come from stockpiles.  Small amounts of
     palladium and platinum are also produced in Canada principally as a by-
     product of nickel and copper mining.

          Supply of palladium is projected to be flat and may, in fact, decline
     in the future. In the past, the primary producer of palladium, Russia, has
     supplied over 64% of what is now a 8.2 million ounce (demand) world market.
     Russia is believed to produce approximately 2.0 million ounces a year as a
     by-product of nickel mining, and the remaining supply has come from
     stockpiles accumulated over the years.  The general consensus in the
     western markets is that the Russian stockpiles of both palladium and
     platinum have declined significantly and will be exhausted within the
     foreseeable future.  However, if it were to be determined that Russia's
     stockpiles of palladium and platinum were extensive, and if they still
     exist and were disposed of in the market, the increased supply could
     adversely affect the market prices of palladium and platinum.

          In addition to these sources it is possible to recover PGMs from
     automotive catalytic converters acquired from scrap yards.  A small but
     growing industry has developed, predominantly in North America, in the
     collection and recovery of PGMs from scrap sources, including automotive
     catalytic converters and electronic and communications equipment.  In 1998,
     the company began processing small shipments of spent automotive catalysts.

     PRICES

          The company's revenue and earnings depend upon world palladium and
     platinum prices. The company has no control over these prices, which tend
     to fluctuate widely.  See "Management's Discussion and Analysis of
     Financial Condition and Results of Operations-Revenue" and "--Factors That
     May Affect Future Results and Financial Condition."  The volatility of
     palladium and platinum prices is illustrated in the following table of the
     annual high, low and average prices per ounce.

                                 RISK FACTORS

     Set forth below are certain risks faced by the company. See also
  "Management's Discussion and Analysis of Financial Condition and Results of
  Operations--Factors That Could Affect Future Results."

  VULNERABILITY TO METALS PRICE VOLATILITY--CHANGES IN SUPPLY AND DEMAND COULD
  REDUCE REVENUES.

     Since the company's sole source of revenue is the sale of platinum group
  metals, changes in the market price of platinum group metals significantly
  impact profitability.  Many factors beyond the company's control influence the
  market prices of these metals.  These factors include global supply and
  demand, speculative activities, international political and economic
  conditions and production levels and costs in other platinum group metal
  producing countries, particularly Russia and South Africa.

     Current economic and political events in Russia could result in declining
  market prices.  If Russia disposes of substantial amounts of platinum group
  metals from stockpiles or otherwise, the increased supply could reduce the
  market prices of palladium and platinum.  Recent political instability in
  Russia and mounting economic problems make Russian stockpiles difficult to
  predict and the risk of sales from stockpiles more significant.  Volatility
  was evident during 1997 and 1998, when apparent tightness in the market for
  platinum group metals led to high prices for current delivery contracts and
  "backwardation," a condition in which delivery prices for metals in the near
  term are higher than delivery prices for metals to be delivered in the future.
  See "--Competition: Platinum and Palladium Market" for further explanation of
  these factors.

     The company enters into hedging contracts from time to time to reduce the
  negative effect of price changes on the company's cash flow.  In the past,
  these hedging activities typically consisted of contracts that required the
  company to deliver specific quantities of metal in the future at specific
  prices, the sale of call options and the purchase of put options.  During the
  first quarter of 1997, the company entered into significant hedging positions,
  particularly in palladium, for sales in 1997 and 1998.  Following that time,
  market prices for palladium to be delivered currently rose sharply.  Because
  the company's contracts were entered into before the price increase,
  deliveries under the hedging contracts during 1997 and 1998 were made at below
  market prices and the company experienced substantial hedging losses.  In
  1998, the company realized $202 per ounce of palladium sold while average
  current delivery prices were $286 per ounce.  Thus, while hedging transactions
  are intended to reduce the negative effects of price decreases, they can also
  prevent the company from benefitting from price increases.  The company's
  below market hedge contracts were closed out during 1998 and the company has
  entered into long-term sales contracts that provide a floor price for sales of
  a portion of the company's production.  For additional discussion of the
  marketing contracts, see "Business and Properties--Current Operations--Sales
  and Hedging Activities."

  EXPANSION PLAN RISKS--ACHIEVEMENT OF THE COMPANY'S LONG-TERM GOALS IS SUBJECT
  TO SIGNIFICANT UNCERTAINTIES.

     The company's achievement of its long-term expansion goals depends upon its
  ability to increase production substantially at the Stillwater Mine and
  related facilities and its ability to develop the East Boulder mine. Each of
  these tasks will require the company to construct mine and processing
  facilities and to commence and maintain production within budgeted levels.
  Although the company believes its goals and preliminary estimates are based
  upon reasonable assumptions, the company may need to revise its plans and
  estimates for the Stillwater Mine and East Boulder project as the projects
  progress. See "--East Boulder Project" and "--Expansion Plans" for further
  discussion of the company's expansion plans. Among the major risks to
  successful completion of the 1998 Expansion Plan are:

                                       18
<PAGE>
 
     .    potential cost overruns during development of new mine operations and
          construction of new facilities;

     .    possible delays and unanticipated costs resulting from difficulty in
          obtaining the required permits; and

     .    the inability to recruit sufficient numbers of skilled underground
          miners.

    In addition, a decrease in the market price for platinum group metals would
limit the company's ability to successfully implement and finance the 1998
Expansion Plan.

    Based on the complexity and uncertainty involved in development projects at
this early stage, it is extremely difficult to provide reliable time and cost
estimates. The company cannot be certain that either the Stillwater expansion or
the development of East Boulder will be completed on time or at all, that the
expanded operations will achieve the anticipated production capacity, that the
construction costs will not be higher than estimated, that the expected
operating cost levels will be achieved or that funding will be available from
internal and external sources in necessary amounts or on acceptable terms.

     The company is not planning to obtain a complete feasibility study or a
final engineering study for the East Boulder project. When an 18,500-foot access
tunnel has been completed, the company will revaluate its geologic and process
analyses, estimates of capital expenditures, cash operating costs and recovery
rates to confirm the feasibility of proceeding with the East Boulder
development. The project's capital costs, operating costs and economic returns
may differ materially from the company's current analyses, which are based
largely on preliminary engineering and cost estimates. The company will proceed
with further development of East Boulder as the engineering studies are
completed and the grade and continuity of the reserves are confirmed.

     East Boulder is a development project and has no operating history. Thus,
estimates of future cash operating costs at East Boulder are based largely on
the company's years of operating experience at the Stillwater Mine portion of
the J-M Reef. Actual cash operating costs and economic returns may differ
significantly from those currently estimated or those established in future
studies and estimates. Although the company anticipates that the operating
characteristics at East Boulder will be similar to the Stillwater Mine, new
mining operations often experience unexpected problems during the development
and start-up phases, which can result in substantial delays in reaching
commercial production.

DEPENDENCE ON AGREEMENTS WITH SIGNIFICANT CUSTOMERS--THE COMPANY'S PROTECTION
FROM LOW PRICES DEPENDS UPON PERFORMANCE OF ITS MARKETING CONTRACTS.

     In the third quarter 1998, the company entered into sales contracts
covering the sale of palladium and platinum over the five-year period from
January 1999 through December 2003. Under these contracts, the company has
committed approximately 90% to 100% of its annual palladium production and 20%
of its platinum production. The marketing contracts contain termination
provisions that allow the purchasers to terminate in the event the company
breaches and the breach is not cured within periods ranging from ten to thirty
days of notice by the purchaser. In addition, the contracts contain force
majeure provisions that allow for the suspension and, in one instance, the
termination of the contract upon the occurrence of certain events, such as "acts
of God," that are beyond the control of a contracting party and that limit the
party's ability to perform the contract.

     The company, therefore, is subject to the customers' compliance with the
terms of the contracts, their ability to terminate or suspend the contracts and
the customers' willingness and ability to pay. In the event the company becomes
involved in a disagreement with one or more of its customers, their compliance
with these contracts may be at risk. For example, the company has negotiated
floor prices that are well above historical low prices for palladium. In the
event of a substantial decline in the market price of palladium, one or more of
these customers could seek to renegotiate the prices or fail to honor the
contracts. In such an event, the company's expansion plans could be threatened.
In addition, under the Scotiabank Credit Facility, a default or modification of
the marketing contracts could prohibit additional loans or require the repayment
of outstanding loans. If the repayment of the credit facility accelerates, the
company may be required to pay the principal and interest due on

                                       19
<PAGE>
 
the 7% Convertible Subordination Notes due 2003. Although the company believes
it has adequate legal remedies if a customer fails to perform, termination or
breach could have a material adverse effect on the company's expansion plans and
results of operations. See "Business and Properties--Current Operations--Sales
and Hedging Activities" for additional information about the marketing
contracts.
 
LIMITED AVAILABILITY OF ADDITIONAL MINING PERSONNEL AND UNCERTAINTY OF LABOR
RELATIONS
 
     The operations of the company depend significantly on the availability of
qualified miners. Historically, the company has experienced high turnover with
respect to its miners. In addition, the company must compete for individuals
skilled in the operation and development of mining properties. The number of
such persons is limited, and significant competition exists to obtain their
skills. The company cannot be certain that it will be able to maintain an
adequate supply of miners and other personnel or that the company's labor
expenses will not increase as a result of a shortage in supply of such workers.
Failure to maintain an adequate supply of miners could adversely effect the
company's expansion plans and results of operations. The company currently has
approximately 916 employees, about 669 of whom are covered by a collective
bargaining agreement with the Oil, Chemical and Atomic Workers Union, expiring
June 30, 1999. The company's inability to negotiate an acceptable contract with
this union or with a new union could result in work stoppages by the affected
employees and increased operating costs as a result of higher wages or benefits
paid. In the event the company's employees were to engage in a strike or other
work stoppage, the company could experience a significant disruption of its
operations and higher ongoing labor costs, which could have a material adverse
effect on the company's business, financial condition and results of operations.

MINING RISKS AND POTENTIAL INADEQUACY OF INSURANCE COVERAGE
 
     Underground mining and the company's milling, smelting and refining
operations involve a number of risks and hazards, including environmental
hazards, industrial accidents, labor disputes, metallurgical and other
processing, smelting or refining problems, unusual and unexpected rock
formations, ground or slope failures, cave-ins, flooding and periodic
interruptions due to inclement or hazardous weather conditions or other acts of
God, mechanical equipment and facility performance problems and the availability
of materials and equipment. Such risks could result in damage to, or destruction
of, mineral properties or production facilities, personal injury or death,
environmental damage, delays in mining, monetary losses and possible legal
liability. Fatalities have occurred at the company's mine since operations began
in 1986. Industrial accidents could have a material adverse effect on the
company's business and operations. Although the company believes that it
maintains insurance within ranges of coverage consistent with industry practice,
it cannot be certain that this insurance will cover the risks associated with
mining or that the company will be able to maintain insurance to cover these
risks at economically feasible premiums. The company might also become subject
to liability for pollution or other hazards which it cannot insure against or
which it may elect not to insure against because of premium costs or other
reasons. Losses from such events could have a material adverse effect on the
company.

ADVERSE EFFECT OF GOVERNMENTAL REGULATIONS--CHANGES TO REGULATIONS AND
COMPLIANCE WITH EXISTING REGULATIONS COULD INCREASE COSTS AND CAUSE DELAYS.
 
     The company's business is subject to extensive Federal, state and local
environmental controls and regulations, including the regulation of discharge of
materials into the environment, disturbance of lands, threatened or endangered
species and other environmental matters. These laws are continually changing
and, as a general matter, are becoming more restrictive. Generally, compliance
with these regulations requires the company to obtain permits issued by Federal,
state and local regulatory agencies. Certain permits require periodic renewal or
review of their conditions. The company cannot predict whether it will be able
to renew such permits or whether material changes in permit conditions will be
imposed. Nonrenewal of permits or the imposition of additional conditions could
have a material adverse effect on the company's financial condition or results
of operations.

     Compliance with existing and future environmental laws and regulations may
require additional control measures and expenditures which the company cannot
predict. Environmental compliance requirements for new

                                       20
<PAGE>
 
mines may require substantial additional control measures that could materially
affect permitting and proposed construction schedules for such facilities. Under
certain circumstances, facility construction may be delayed pending regulatory
approval. Expansion will require new environmental permitting at the Stillwater
Mine and mining and processing facilities at the East Boulder project.

     For example, in April 1996, the company submitted a permit amendment
application for the expansion of the Stillwater Mine. This expansion proposal
includes selection and construction of a new tailings impoundment and removal of
the 2,000 tons of ore per day production cap. During 1997, as a result of this
application, the Montana DEQ began preparation of an Environmental Impact
Statement in order to assess the environmental impacts of the amendment. The
Montana DEQ issued the final Environmental Impact Statement in 1998, subsequent
to review of draft issuances and a public hearing. In November 1998, the Record
of Decision was issued by the Montana DEQ and the USFS. There were no material
changes from the original application. An environmental group filed a comlaint
to challenge the adequacy of the Environmental Impact Statement and reclamation
provisions developed in connection with the amendment to the permit. The
complaint has not been served and it is difficult to predict whether or how it
may by pursued.

     The company's activities are also subject to extensive Federal, state and
local laws and regulations governing matters relating to mine safety,
occupational health, labor standards, prospecting, exploration, production,
exports and taxes. Compliance with these and other laws and regulations could
require significant capital outlays. The company has not experienced any
material difficulty emanating from these extensive laws and regulations in the
past, nor does it have any basis to expect any material difficulty in the
future. The company believes that it has successfully complied in all material
respects with all Federal, state and local requirements for the current
operations and planned expansion of its mining activities at the Stillwater
Mine.
 
POTENTIAL NEGATIVE IMPACT OF NEW MINING LEGISLATION
 
     New laws and regulations, amendments to existing laws and regulations, or
more stringent enforcement of existing laws and regulations could have a
material adverse impact on the company's results of operations and financial
condition. In the worst case, such amendments could render the company's mining
operations uneconomic. During the 1998 legislative session, legislation was
introduced into the United States Congress that proposed a number of
modifications to the General Mining Law, which governs the location and
maintenance of unpatented mining claims and related activities on federal lands.
Among those modifications were proposals which would have:

 .  imposed a royalty on production from unpatented mining claims;

 .  imposed a fee on production from patented mining claims;

 .  increased the cost of holding mining claims; and

 .  imposed more specific federal reclamation requirements on operations on
   mining claims.

     None of those proposed modifications were enacted into law; however,
similar legislative proposals have been introduced in 1999. The potential impact
on the company as a result of congressional action is difficult to predict, but
legislation amending the General Mining Law could adversely affect the company's
ability to economically develop the J-M Reef, virtually all of which is
comprised of unpatented mining claims on federal lands.

DEPENDENCE ON A SINGLE MINE--THE STILLWATER MINE IS THE COMPANY'S SOLE SOURCE OF
REVENUES.

     All of the company's revenues are currently derived from its mining
operations at the Stillwater Mine. Although the company has not experienced any
serious production interruption since production began in 1987, an interruption
in operations at the Stillwater Mine or at any of the company's processing
facilities would have a material adverse effect on the company's ability to
generate revenues and profits in the future.

                                       21

  UNCERTAINTY OF TITLE TO PROPERTIES

       The validity of unpatented mining claims on public lands, which
  constitute most of the property holdings of the company, is often uncertain
  and may be contested and subject to title defects.  Unpatented mining claims
  may be located on U.S. federal public lands open to appropriation, and are
  generally considered to be subject to greater title risk than other real
  property interests because the validity of unpatented mining claims is often
  uncertain and is always subject to challenges of third parties or contests by
  the federal government.  The validity of an unpatented mining claim or
  millsite, in terms of its location and its maintenance, depends on strict
  compliance with a complex body of federal and state statutory and decisional
  law and, for unpatented mining claims, the existence of a discovery of
  valuable minerals.  In addition, few public records exist to definitively
  control the issues of validity and ownership of unpatented mining claims or
  millsites.  While the company has obtained various reports, opinions and
  certificates of title for some of the unpatented mining claims or millsites it
  owns or to which it has the rights in accordance with what the company
  believes is industry practice, the company cannot be certain that the title to
  any of its claims may not be defective.

  DIFFICULTY OF ESTIMATING RESERVES ACCURATELY

       While the company's 1998 ore reserves have been affirmed and verified by
  independent consultants, the ore reserve estimates are necessarily imprecise
  and depend to some extent on statistical inferences drawn from limited
  drilling, which may prove unreliable.  Reserve estimates are expressions of
  judgment based on knowledge, experience and industry practice.  Although the
  company believes its estimated ore reserves are well established, it cannot be
  certain that its estimated ore reserves are accurate, and future production
  experience could differ materially from such estimates.  Should the company
  encounter mineralization or formations at any of its mines or projects
  different from those predicted by drilling, sampling and similar examinations,
  reserve estimates may have to be adjusted and mining plans may have to be
  altered in a way that might adversely affect the company's operations.
  Declines in the market prices of platinum group metals may render the mining
  of some or all of the company's ore reserves uneconomic.  The grade of ore may
  vary significantly from time to time and the company cannot give any
  assurances that any particular level of metal may be recovered from the ore
  reserves.  Moreover, short-term factors relating to the ore reserves, such as
  the need for additional development of the ore body or the processing of new
  or different grades, may impair the profitability of the company in any
  particular accounting period.

  COMPLEXITY OF PROCESSING PLATINUM GROUP METALS

       Producers of platinum group metals are required to conduct additional
  processing procedures and construct and operate additional facilities compared
  to gold and silver producers. In addition to concentration facilities at the
  mine site, the company operates its own smelting and base metals refining
  facilities in Columbus, Montana to produce a filter cake that is shipped for
  final refining by a third party refiner. The operations of a smelter and
  refinery by the company require environmental steps and operational expertise
  not required of most other precious metals producers. Though the company has
  not experienced any material adverse effects to date, this additional
  complexity of operations poses additional operational and environmental risks.

(1)  Revenues consist of the sales revenue for palladium and platinum, including
     any hedging gain or loss. By-product metals revenue and secondary materials
     processing revenue are included as a reduction of cost of metals sold.
(2)  Capitalized interest for the years ended December 31, 1998, 1997 and 1996
     totaled $2.1 million, $1.5 million and $2.2 million, respectively.
(3)  Upon early extinguishment of notes issued in connection with the 1994
     private placement, the unamortized balance of deferred debt issue costs of
     $925,000 ($568,000 net of taxes) was charged against income as an
     extraordinary item.
(4)  Net income for 1996 reflects a change in accounting policy which became
     effective January 1, 1996. Pursuant to this policy, the company changed its
     method of accounting for mine development expenditures by capitalizing
     certain direct and indirect costs related to development activities, which
     were previously expensed. The effect of the accounting change on 1996
     results was to increase net income by approximately $5.2 million ($0.17 per
     share). Assuming the accounting change had been applied retroactively, the
     unaudited pro forma effect would have been an increase in net income of
     $3.0 million ($0.10 per share) in 1995.
(5)  In 1997, the company adopted SFAS No. 128, Earnings per Share, which
     requires the presentation of basic and diluted earnings per share. All

(9)  Ounces produced is defined as the number of ounces produced from the
     concentrator during the period reduced by losses expected to be incurred in
     subsequent smelting and refining processes. Differences in ounces produced
     and ounces sold are caused by the length of time required by the smelting
     and refining processes.
(10) A combined average realized price of palladium and platinum is reported at
     the same ratio as ounces are produced from the base metals refinery. Cash
     costs include cash costs of mining, processing and administrative expenses
     at the mine site (including overhead, taxes other than income taxes,
     royalties and credits for metals produced other than palladium and
     platinum.) Total costs of production include cash costs plus depreciation
     and amortization. Income taxes, corporate general and administrative
     expenses and interest income and expense are not included in either total
     or cash costs.

                                    ITEM 7
                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

          The following discussion should be read in conjunction with the
     company's Consolidated Financial Statements and Notes, included elsewhere
     in this report, and the information contained in "Selected Financial and
     Operating Data."                   

      PRODUCTION

         The company mines, processes and refines palladium, platinum, and
     associated metals from the J-M Reef in Montana. The company conducts its
     mining operations at the Stillwater Mine, and recently announced its 1998
     Expansion Plan intended to reach an annualized rate of PGM production of
     1.2 million ounces before year end 2001. The company plans to expand
     existing operations at the Stillwater Mine and develop the East Boulder
     site. See "Business and Properties--1998 Expansion Plan."

          The company's production of palladium and platinum is determined by
     the tons of ore mined, the mill head grade (ounces of precious metal per
     ton of mined ore) and metallurgical recovery. The company defines its mine
     production as those ounces contained in concentrate when it is shipped to
     the company's smelter, which generally occurs within four days of the ore
     being mined. The company records revenue when partially-refined ounces are
     shipped from its base metals refinery to a third-party refiner for final
     processing. Shipment from the base metals refinery to a third-party refiner
     generally occurs within 15 to 18 days of mining. Approximately 40 days
     elapse between the time ore is extracted from the Stillwater Mine and the
     time ounces of precious metal contained in that ore are made available to
     the company by a third-party refiner. Because of the length of the
     processing cycle and the different cutoff points for identifying production
     and sales, production may not always correspond to sales in a particular
     accounting period. However, any production not shipped from the base metals
     refinery at the end of an accounting period is generally shipped during the
     first two weeks of the subsequent period.

          In 1994, the company commenced a major expansion project designed to
     double ore throughput at its Nye, Montana operation to 2,000 tons of ore
     per day. This expansion effort was completed in mid-1997, and during the
     fourth quarter of that year, the company successfully attained its 2,000
     tons of ore per day goal. Increases in ore tonnage in 1997 and 1998 were
     achieved by the company as a result of the operation of the new 1950-foot
     shaft and the underground crusher and conveyor system. Also, the company
     added manpower, increased the number of active stopes and improved
     productivity, principally through the increase of mechanized mining
     methods.

          The ore grade of the company's reserves is generally consistent, but,
     as is common in an underground mine, the grade mined and the recovery rate
     achieved will vary from period to period. In particular, mill head grade
     can be expected to vary by up to 10% from quarter to quarter. During 1998,
     the average mill head grade of ore processed was 0.69 ounce of PGMs per ton
     of ore. During 1997, the average mill head grade of ore processed was 0.70
     ounce of PGMs per ton of ore, compared to the 1996 average mill head grade
     of 0.67 ounce of PGMs per ton of ore.

     REVENUE

          The company's revenue and earnings are significantly influenced by
     worldwide prices of palladium and platinum, which can be volatile and over
     which the company has no control. Sales to significant customers
     represented approximately 60%, 90% and 98% of total revenues for the years
     ended December 31, 1998, 1997 and 1996, respectively. The company sells its
     metals to a small number of customers and brokers; however, the company
     may, if the need were to arise, readily sell its metal in markets
     throughout the world.

                                       28
<PAGE>
 
          Until the second quarter of 1997, the company used basic hedging
  techniques involving spot deferred forward contract commitments and put and
  call options to attempt to lock in prices for its production, benefit from
  price increases and protect against price decreases.  During the first quarter
  of 1997 the company entered into significant hedge positions, particularly for
  palladium, for 1997 and 1998.  These hedging contracts, which expired in 1998
  precluded the company from obtaining the benefit of increased market palladium
  prices in 1997 and 1998.  As a result, the company's revenues were unfavorably
  impacted, in 1998 with the company's combined average 1998 realized price for
  palladium falling about 29% below the combined average 1998 market price.
  These below market hedge contracts matured and the metal was delivered by the
  close of 1998.  The objective of the company's hedging policy in the future
  will be to benefit from upward price movements while providing floor prices to
  reduce the company's exposure to downside price movements.  Pursuant to this
  policy, the company entered into sales contracts to sell approximately 90% to
  100% of its palladium production and 20% of its platinum production from 1999
  through 2003.  Palladium sales under these contracts will be at a slight
  discount to market prices.  These contracts provide for an average floor price
  of approximately $225 per ounce on substantially all of the company's annual
  production and an average maximum price of $400 per ounce on approximately 30%
  of production. The 20% of the company's platinum production covered by these
  contracts will be sold at a slight discount to market prices, subject to floor
  of $350 per ounce and a cap of $425 per ounce.  See "Risk Factors--Dependence
  on Agreements with Significant Customers."

  COST STRUCTURE

       The company's current operating costs per ounce have improved
  significantly as a result of increased production at the Stillwater Mine.
  Cash costs of production include cash costs of mining, processing, general and
  administrative expenses at the minesite, royalties and taxes other than income
  taxes and are net of byproduct metals revenue.  Mine site general and
  administrative expenses include overhead, taxes other than income, and
  royalties.  Operating efficiencies were achieved through economies of scale as
  production increased.  In addition, material handling and material processing
  efficiencies were realized once the underground shaft was commissioned in June
  1997, as the shaft provided a more automated method for transporting ore and
  waste underground.  Finally, the successful implementation of controls to
  minimize mine dilution also had a favorable impact on the company's cost
  structure.  Management expects these operating efficiencies will continue to
  be realized in the future.

                             RESULTS OF OPERATIONS

     YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31, 1997

          PGM Production.  Total ore tons mined in the year ended December 31,
          --------------                                                      
     1998 increased 24% to 720,000 tons, from 580,000 tons for the year ended
     December 31, 1997.  Tons milled in 1998 averaged about 2,000 tons of ore
     per day compared with an average of 1,600 tons of ore per day milled in
     1997.  Increases in ore tonnage were achieved as a result of the mine
     expansion, primarily through operating efficiencies gained by commencing
     underground ore crushing, adding mine manpower and improving stoping
     productivity. Enhanced stoping productivity was driven by an increase in
     mechanized mining to almost 85% of 1998 tons mined, up from 80% in 1997.

          The average head grade of ore delivered to the mill was 0.69 ounces
     per ton in 1998, compared to 0.70 ounce per ton achieved in 1997.
     Metallurgical recovery was 91% in 1998, compared to 89% in 1997 and is the
     result of the use of additional flotation cells installed to increase
     retention time in flotation.

          Palladium and platinum production increased 25% to 444,000 ounces for
     the year ended December 31, 1998 from 355,000 ounces in 1997.  Once again,
     this substantial improvement in production was primarily the result of the
     mine expansion and, more specifically, was driven by the increase in tons
     milled during 1998, coupled with an improvement in the recovery rate
     resulting from the installation of three additional flotation cells earlier
     in the year.

     the result of higher production levels and higher realized PGM prices.

          Palladium sales increased to 337,000 ounces in 1998 from 288,000
     ounces in 1997. Platinum sales increased to 103,000 ounces in 1998 from
     91,000 ounces in 1997.  Total sales of metal increased 16% to 440,000
     ounces in 1998 from 379,000 ounces in 1997, primarily due to significantly
     higher production levels achieved in 1998.

          The combined average realized price per ounce of palladium and
     platinum sold in 1998 was $243 per ounce, compared to $203 per ounce in
     1997, while the combined average market price rose about 32% to $304 per
     ounce in 1998, compared with $230 per ounce in 1997. The company was unable
     to realize the average market price for palladium in 1998 because of its
     inability to defer delivery upon favorable terms on its market deferred
     palladium forward contracts due to continued severe backwardation in the
     palladium markets during 1997 and 1998. The average realized price per
     ounce of platinum sold was $377 per ounce in 1998, a decline of 3% compared
     with $388 per ounce in 1997.  The platinum market price was $372 per ounce
     in 1998 compared to $395 per ounce in 1997.  The average realized price per
     ounce of palladium was $202 per ounce in 1998 compared to $144 per ounce
     for 1997, while the average market price increased 61% to $286 per ounce in
     1998 from $178 per ounce in 1997.

          Costs and Expenses.  Cash production costs per ounce in the year ended
          ------------------                                                    
     December 31, 1998 decreased $23, or 13%, to $151 per ounce from $174 per
     ounce in the year ended December 31, 1997, primarily the result of a 25%
     increase in metal production.  Total production costs per ounce in the year
     ended December 31, 1998 decreased $29, or 14% to $178 per ounce from $207
     per ounce in the year ended December 31, 1997.  This decrease is also
     primarily due to increased metal production.

          Operating Income (Loss).  The company reported operating income of
          -----------------------                                           
     $23.2 million for the year ended December 31, 1998, compared with an
     operating loss of $6.2 million for 1997.  The higher operating income was
     mainly the result of increased metal production and higher realized prices.
     For 1998, general and administrative costs were $5.1 million compared with
     $3.5 million in 1997.

          Net Income (Loss).  Primarily as a result of increased operating
          -----------------                                               
     income, the company has provided for income taxes of $8.4 million compared
     to a reported benefit of $3.4 million for the year ended December 31, 1997.
     As a result the company reports net income of $13.4 million for the year
     ended December 31, 1998 compared with net loss of $5.4 million in 1997.

     YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996

          PGM Production.  Total ore tons mined in the year ended December 31,
          --------------                                                      
     1997 increased 37% to 580,000 tons from 424,000 tons for the year ended
     December 31, 1996.  Tons milled in 1997 averaged about 1,600 tons of ore
     per day compared with an average of 1,200 tons of ore per day milled in
     1996.  Increases in ore tonnage were achieved as a result of the mine
     expansion, primarily through operating efficiencies gained by commencing
     underground ore crushing, adding mine manpower and improving stoping
     productivity. Enhanced stoping productivity was driven by an increase in
     mechanized mining to almost 80% of 1997 tons mined, up from 60% in 1996.

          The average head grade of ore delivered to the mill was 0.70 ounce per
     ton in 1997, an increase over the 0.67 ounce per ton achieved in 1996.  The
     mill head grade increased primarily due to successful implementation of
     controls to minimize mining dilution.  Additionally, commissioning of the
     production shaft in June 1997 produced greater efficiencies in material
     handling and subsequent material processing through the mill.

          Palladium and platinum production increased 39% to 355,000 ounces for
     the year ended December 31, 1997 from 255,000 ounces in 1996.  Once again,
     this substantial improvement in production was primarily 

                                       30
<PAGE>
 
     the result of the mine expansion and, more specifically, was driven by the
     increase in tons milled during 1997 and a higher average mill head grade,
     coupled with an improvement in the recovery rate resulting from the
     installation of three additional flotation cells earlier in the year .

          Revenues.  Revenues were $76.9 million for the year ended December 31,
          --------                                                              
     1997 compared with $56.2 million in 1996, an increase of 37%.

          Palladium sales increased to 288,000 ounces in 1997 from 214,000
     ounces in 1996.  Platinum sales increased to 91,000 ounces in 1997 from
     62,000 ounces in 1996. Total sales of metal increased 37% to 379,000 ounces
     in 1997 from 276,000 ounces in 1996, primarily due to significantly higher
     production levels achieved in 1997 as a result of the 1994 mine expansion.
     Effective January 1, 1997, the company changed its method of revenue
     recognition whereby revenue is recognized when product is shipped from the
     company's base metals refinery to an external refiner.  This change made
     the company's revenue recognition policy more comparable with other
     precious metals producers.  The cumulative effect of this change as of
     January 1, 1997 was to increase revenue by approximately $2.7 million in
     the first quarter of 1997; the effect on net income was not material.

          The combined average realized price per ounce of palladium and
     platinum sold in 1997 was $203 per ounce, roughly the same as 1996, while
     the combined average spot price rose about 20% to $230 per ounce in 1997,
     compared with $191 per ounce in 1996. The average realized price per ounce
     of palladium remained constant at $144 per ounce for both 1997 and 1996,
     while the average spot price increased 39% to $178 per ounce in 1997 from
     $128 per ounce in 1996.  The average realized price per ounce of platinum
     sold was $388 per ounce in 1997, a decline of 5% compared with $410 per
     ounce in 1996.  The platinum spot price remained about the same in both
     years at $395 per ounce. The company was unable to realize the average spot
     price for palladium in 1997 because of its inability to defer delivery upon
     favorable terms on its spot deferred palladium forward contracts due to
     continued severe backwardation in the palladium markets during 1997.

          Costs and Expenses.  Cash costs per ounce of metal produced in the
          ------------------                                                
     year ended December 31, 1997 decreased $10 to $174 per ounce from $184 per
     ounce in the year ended December 31, 1996, primarily the result of a 39%
     increase in metal production.  Total costs per ounce of metal produced in
     the year ended December 31, 1997 decreased $12 to $207 per ounce from $219
     per ounce in the year ended December 31, 1996.  This decrease is also
     primarily due to increased metal production.

          Operating Income (Loss).  The company incurred an operating loss of
          -----------------------                                            
     $6.2 million for the year ended December 31, 1997, compared with an
     operating loss of $5.2 million for 1996.  The higher operating loss was
     mainly the result of a $1.1 million increase in general and administrative
     costs.  For 1997, general and administrative costs were $2.9 million
     compared with $1.8 million in 1996.  The $2.9 million of expenses for 1997
     included approximately $1.6 million of non-recurring severance costs and
     professional fees related to changes in the company's business processes
     and management structure and the reorganization of the company's Board of
     Directors.  The decrease in costs per ounce for the current year was driven
     by significantly higher production in 1997, about 39% more than in 1996.
     Operating efficiencies also contributed to the lower cost per ounce.

          Net Income (Loss). The company realized a net loss of $5.4 million for
          -----------------               
     the year compared with net income of $11.1 million in 1996, when results
     included the cumulative effect of an accounting change. Absent this
     accounting change, the net loss for 1996 was $2.8 million. The larger net
     loss in 1997 was driven by lower realized platinum prices, reduced interest
     income on lower cash balances and increased net interest expense.

                        LIQUIDITY AND CAPITAL RESOURCES


               The company's working capital at December 31, 1998 was $58.8
     million compared to $23.1 million at December 31, 1997.  The ratio of
     current assets to current liabilities was 3.2 at December 31, 1998,
     compared to 2.9 at December 31, 1997.

          Net cash provided by operations for the year ended December 31, 1998
     was $31.4 million compared with cash used in operations of $1.3 million in
     1997, an increase of $32.7 million.  The increase is a result of increased
     net income of $18.8 million and an increase in the provision for deferred
     income taxes of $11.7 million in 1998 as compared to 1997.

          A total of $54.8 million of cash was used in investing activities in
     1998 compared to $12.1 million in 1997.  The increased usage was primarily
     due to an increase in capital expenditures as a result of the development
     of the East Boulder project and the Stillwater Mine expansion.

          For the year ended December 31, 1998, cash flow from financing
     activities was $69.0 million compared to $1.2 million for the year ended
     December 31, 1997.  The increase is primarily due to the completion in the
     fourth quarter of 1998 of 2.3 million common share offering which provided
     approximately $67 million.

          As a result of the above, cash and cash equivalents increased by $45.6
     million for the year ended December 31, 1998, compared with a decrease of
     $12.2 million in the comparable period of 1997.

          In September 1998, the company completed the sale leaseback of a
     tunnel boring machine and miscellaneous other mining equipment. The leases
     are classified as operating leases for financial reporting purposes and are
     non-cancellable with terms of seven years. The annual rental payments
     during the term of the leases are approximately $1.6 million.

          In 1998, the company announced plans to expand the Stillwater Mine and
     to develop East Boulder. Total capital to fund the expansion is expected to
     approximate $385 million. Of this, the Stillwater Mine expansion is
     expected to cost about $75 million; East Boulder is expected to cost
     approximately $270 million; and approximately $40 million is designated for
     the expansion of the company's smelter and base metals refinery located in
     Columbus, Montana. During 1999, the company expects to invest approximately
     $200 million on capital items, including capitalized interest of $6
     million.

          Cash flow from operating activities is not expected to be sufficient
     to cover 1999 capital expenditures. Based on cash and short-term
     investments on hand and expected cash flows from operations, along with
     existing credit facilities of $175 million, management believes there is
     sufficient liquidity to meet 1999 operating and capital needs. The company
     may, from time to time, also seek to raise additional capital from the
     public or private securities markets or from other sources for general
     corporate purposes and for investments beyond the scope of the current
     phase of its current expansion plans.

          The company has obtained a seven-year $175 million credit facility
     from a syndicate of banks led by the Bank of Nova Scotia. The facility
     provides for a $125 million term loan facility and a $50 million revolving
     credit facility. Borrowings may be made under the term loan facility until
     December 31, 2000 and amortization of the term loan facility will commence
     on March 31, 2001. The final maturity of the term loan facility and
     revolving credit facility will be December 31, 2005.

          The loans will be required to be prepaid from excess cash flow,
     proceeds from asset sales and the issuance of debt or equity securities,
     subject to specified exceptions. Proceeds of the term loan facility will be
     used to finance a portion of the 1998 Expansion Plan. Proceeds of the
     revolving credit facility will be used for general corporate and working
     capital needs. At the company's option, the Scotiabank Credit Facility will
     bear

                                       32
<PAGE>
 
     interest at LIBOR or an alternate base rate, in each case plus a margin.
     The interest rate may be adjusted depending upon the company's ratio of
     debt to operating cash flow. Substantially all the property and assets of
     the company and its subsidiaries and the stock of the company's
     subsidiaries have been pledged as security for the Scotiabank Credit
     Facility.

          Conditions precedent to both initial and subsequent borrowing under
     the term loan facility and revolving credit term loan facility and
     revolving credit facility include: (1) continued performance of the
     marketing contracts; (2) receipt of satisfactory milestone reports
     regarding the 1998 Expansion Plan; and (3) receipt of all government and
     third party approvals necessary or advisable for the 1998 Expansion Plan.

          Covenants in the Scotiabank Credit Facility restrict: (1) additional
     indebtedness; (2) payment of dividends or redemption of capital stock; (3)
     liens; (4) investment, acquisitions, dispositions or mergers; (5)
     transactions with affiliates; (6) capital expenditures (other than those
     associated with the 1998 Expansion Plan); (7) refinancing or prepayment of
     subordinated debt (excluding an underwritten call or conversion of the
     company's 7% Convertible Subordinated Notes Due 2003); (8) changes in the
     nature of business conducted or ceasing operations at the principal
     operating properties; and (9) commodities hedging to no more than 90% of
     annual palladium production and 75% of annual platinum production
     (excluding the sales covered by the company's marketing contracts and
     similar agreements). The company also is subject to financial covenants
     including a debt to operating cash flow ratio, is debt service coverage
     ratio and a debt to equity ratio.

          Events of default include: (1) a cross-default to other indebtedness
     of the company or its subsidiaries; (2) any material modification to the
     life-of-mine plan for the Stillwater Mine; (3) a change of control of the
     company; (4) the failure to maintain annual palladium production of at
     least 315,000 ounces in the year 2000 and at least 490,000 ounces each year
     thereafter or (5) any breach or modification of any of the sales contracts.
     Default under the Scotiabank Credit Facility may constitute a default under
     the indenture associated with the Convertible Notes. The indenture for the
     Convertible Notes also contains standard covenants and provisions for
     events of default.

          In addition, the company had an unsecured working capital line of
     credit with N M Rothschild & Sons Limited, with a maximum borrowing
     capacity of $15 million. As of December 31, 1998, there were no borrowings
     against this credit line, and the company could borrow up to $9.3 million
     based upon quarterly borrowing calculations under the terms of the
     agreement. This facility was cancelled concurrent with completion of the
     Scotiabank Credit Facility.

     MARKET RISK
     -----------

          The company may from time to time utilize derivative instruments to
     financial risk. The company has no material derivative position as of
     December 31, 1998. During the third quarter of 1998, the company entered
     into sales contracts with General Motors Corporation, Ford Motor Company,
     Mitsubishi Corporation and KEMET Corp. These contracts cover the company's
     PGM production over the five-year period from January 1999 through December
     2003. During this period, the company has committed between 90% to 100% of
     its actual palladium production and approximately 20% of its planned annual
     platinum production. Palladium and platinum sales are priced at a slight
     discount to market, with floor prices on substantially all of the company's
     production committed under these contracts averaging $225 per ounce of
     palladium and $350 per ounce of platinum. The company has also agreed to an
     average maximum price of approximately $400 per ounce on approximately 30%
     of its palladium production and $425 per ounce on approximately 20% of its
     planned annual platinum production.



                           ENVIRONMENTAL OBLIGATIONS

          The company focused on one significant environmental project during
     1998. This project involved securing an amendment to the company's existing
     permit from the Montana Department of Environmental Quality which provided
     for a substantial increase in throughput at the Stillwater Mine site and
     construction of

                                       33
<PAGE>
 
a tailings facility on a tract of land owned by the company in Stillwater
County, Montana. The costs associated with this permitting effort were $0.3
million in 1998 and $0.3 million in 1997. The company does not expect to incur
additional costs in connection with the project. The company does not anticipate
incurring any significant capital or unusual operating expenditures for other
environmental compliance within the next 12 months. In the first quarter of
1999, an environmental group filed a complaint against the Montana Department of
Environmental Quality challenging the adequacy of the Environmental Impact
Statement and reclamation provisions developed in connection with the permit
amendment. The company believes the complaint is without merit. In 1998, the
company's environmental expenses were $0.6 million and capital expenditures for
environmental equipment were $0.1 million. The company incurred $1.0 million in
environmental-related costs during 1997, of which half were expensed and half
were for purchases of environmental equipment. The company's ongoing operating
expenditures for environmental compliance are expected to be approximately $0.8
million per year.

     The company is presently required to post surety bonds with the State of
Montana in the amount of $11.1 million, which also represents the company's best
estimate of mine closure and reclamation costs for current operations. The
company does not believe that costs will materially exceed this estimate. The
company is accruing for reclamation costs over the life of the Stillwater Mine
based on current production levels and estimated proven and probable reserves.
On December 31, 1998 and 1997, the accrued liability was $0.7 million. The
company periodically reviews the adequacy of its reclamation and mine closure
obligations in light of current laws and regulations and will adjust its
estimate as necessary.

                               YEAR 2000 ISSUES

     Year 2000 will impact computer programs written using two digits rather
than four to define the applicable year. Any programs with time-sensitive
software may recognize a date using "00" as the year 1900 rather than the year
2000. This could result in a system failure or miscalculation causing
disruptions of operation, including a temporary inability to process
transactions, send invoices or engage in other ordinary activities. This problem
largely affects software programs written years ago, before the issue came to
prominence. The company primarily uses third-party software programs written and
updated by outside firms, and the company is in the process of determining
whether this software is Year 2000 compliant. In May 1996, the company began the
implementation of a new information technology infrastructure that the company
believes will be fully Year 2000 compliant. This infrastructure will be in place
by the fourth quarter of 1999. The company does not believe that the costs
associated with additional Year 2000 compliance will be material.

     The company has set in motion an effort to obtain written assurances from
its material suppliers regarding their Year 2000 compliance. As a result of this
effort, the company expects to generate by the second quarter of 1999 a
validated list of suppliers that are Year 2000 compliant, and will use the
entities on this list to obtain its supplies.

     The company has also begun the process of obtaining written assurances from
the company's material customers regarding their Year 2000 compliance. The
company's goal is to obtain by the second quarter of 1999 written assurances
from customers that they are Year 2000 compliant or that they are expecting to
become Year 2000 compliant before December 31, 1999. In addition, the company is
developing contingency plans to deal with potential Year 2000 risks that could
occur as a result of power failures or the failure of other critical systems.

     Although the company has taken significant steps to address the Year 2000
problem, there can be no assurance that the failure of the company and/or its
material customers or suppliers to timely attain Year 2000 compliance will not
materially reduce the company's revenues or income, or that these failures
and/or the impacts of broader compliance failures by telephone, mail, data
transfer or other utility or general service providers or government or private
entities will not have a material adverse effect on the company.

                  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA


                             REPORT OF MANAGEMENT

     Management is responsible for the preparation of the accompanying financial
statements and for other financial and operating information in this report.
Management believes that its accounting systems and internal accounting
controls, together with other controls, provide assurance that all accounts and
records are maintained by qualified personnel in requisite detail, and
accurately and fairly reflect transactions of Stillwater Mining Company in
accordance with established policies and procedures.

     The Board of Directors has an Audit Committee, none of whose members are
officers or employees of the company or its affiliates. The Audit Committee
recommends independent accountants to act as auditors for the company; reviews
the company's financial statements; confers with the independent accountants
with respect to the scope and results of their audit of the company's financial
statements and their reports thereon; reviews the company's accounting policies,
tax matters and internal controls; and oversees compliance by the company with
the requirements of federal regulatory agencies. Access to the Audit Committee
is given to the company's financial and accounting officers and independent
accountants.

                       REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors and Shareholders of
Stillwater Mining Company


     In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of operations, of cash flows and of changes in
shareholders' equity present fairly in all material respects, the financial
position of Stillwater Mining Company and its subsidiary at December 31, 1998
and 1997, and the results of their operations and their cash flows for each of
the three years in the period ended December 31, 1998, in conformity with
generally accepted accounting principles. These financial statements are the
responsibility of the company's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

     As discussed in Note 2, the company changed its method of accounting for
mine development expenditures in 1996.

                                    NOTE 1
                             NATURE OF OPERATIONS

     Stillwater Mining Company, a Delaware corporation, is engaged in the
exploration, development, extraction, processing and refining of palladium,
platinum and associated minerals from the J-M Reef located in Stillwater and
Sweet Grass Counties, Montana. The J-M Reef is a twenty-eight (28) mile long
geologic formation containing the highest known grade deposit of platinum group
metals in the world.

     The company's operations consist of the Stillwater Mine, a fully permitted
minesite located on the J-M Reef in Nye, Montana, the East Boulder project, a
fully permitted development project located at the western end of the J-M Reef
in Sweet Grass County, Montana and a smelter and base metals refinery located in
Columbus, Montana.

     During 1998, the company announced plans to accelerate the expansion of the
Stillwater Mine, development of the East Boulder project and expansion of the
smelter and base metals facilities.  Key components of the expansion are
development of the Stillwater Mine and concentrator facilities to expand
production from 2,000 tons per day to 3,000 tons per day, development of the
East Boulder mine and ancillary facilities to provide for an initial production
rate of 2,000 tons per day and expansion of the smelter and base metals
refinery.  The company plans to reach an annual production rate of approximately
1.2 million ounces of palladium and platinum during 2001.

     The company's operations can be significantly impacted by risks and
uncertainties associated with the mining industry as well as those specifically
related to its operations.  The risks and uncertainties that can impact the
company include but are not limited to the following:  price volatility of
palladium and platinum, economic and political events affecting supply and
demand for these metals, reserve estimation, exploration and development,
environmental obligations, government regulations and ownership of and access to
mineral reserves.

                                    NOTE 2
                  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

     The accompanying consolidated financial statements include the accounts of
Stillwater Mining Company and its wholly owned subsidiary (collectively referred
to as the "company").  All intercompany transactions and balances have been
eliminated in consolidation.  Certain prior year amounts have been reclassified
to conform with current year presentation.

USE OF ESTIMATES

     The preparation of the company's consolidated financial statements in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect the amounts reported in these
consolidated financial statements and accompanying notes.  The more significant
areas requiring the use of management's estimates relate to mineral reserves,
reclamation and environmental obligations, valuation 

                                       42
<PAGE>
 
allowance for deferred tax assets, useful lives for depreciation and
amortization, and future cash flows from long-lived assets. Actual results could
differ from these estimates.

CASH AND CASH EQUIVALENTS

     The company considers all highly-liquid investments purchased with a
maturity of three months or less to be cash equivalents. As of December 31, 1998
and 1997, cash and cash equivalents included $4.1 and $4.2 million of cash,
respectively. The balance of reported amounts consist principally of investment
grade commercial paper. Amounts reported represent cost which approximates fair
value.

SHORT-TERM INVESTMENTS

     Short-term investments may consist of corporate bonds and commercial paper.
Short-term investments are carried at amortized cost, which approximates fair
value, as the company has the ability and intent to hold to maturity.

INVENTORIES

     Metals inventories are carried at the lower of current market value or
cost. Production costs include the cost of direct labor and materials,
depreciation and amortization, as well as administrative expenses relating to
mining and processing activities. Materials and supplies inventories are valued
at the lower of average cost or fair market value.

PROPERTY, PLANT AND EQUIPMENT

     Property, plant and equipment are recorded at cost and depreciated using
the straight-line method over estimated useful lives ranging from five to twenty
years or, for capital leases, the term of the related leases. Maintenance and
repairs are charged to operations as incurred. Mine development expenditures
incurred to increase existing production, develop new ore bodies or develop
mineral property substantially in advance of production are capitalized and
amortized using a units-of-production method over the proven and probable
reserves. Interest is capitalized on expenditures related to construction or
development projects and amortized using the same basis of depreciation as the
related asset. Capitalization is discontinued when the asset is placed into
operation or development ceases. Exploration costs are expensed as incurred.

     Effective January 1, 1996, the company changed its method of accounting for
mine development expenditures whereby certain direct and indirect costs related
to development activities, which were previously expensed as incurred, are now
capitalized.  This change is believed to better present current income from
mining activities because it results in a better matching of expenses with the
revenue generated as a result of those expenses.  The effect of the accounting
change on 1996 results was to increase net income by approximately $5.2 million
($0.17 per share).

     The company follows SFAS No. 121, Accounting for the Impairment of Long-
Lived Assets and for Long-Lived Assets to be Disposed of. SFAS No. 121
prescribes that an impairment loss is recognized in the event that 

                                       43
<PAGE>
 
facts and circumstances indicate that the estimated carrying amount of an asset
may not be recoverable and an estimate of future undiscounted cash flows is less
than the carrying amount of the asset. Impairment is recorded based on an
estimate of future discounted cash flows. As of December 31, 1998, the company
does not believe that any impairments have occurred.

FAIR VALUE OF FINANCIAL INSTRUMENTS

     The company's non-derivative financial instruments consist primarily of
cash and short-term investments, accounts receivable and debt. The carrying
amounts of cash, short-term investments and accounts receivable approximate fair
value due to their short maturities. At December 31, 1998 and 1997, based on
rates available for similar types of obligations, the fair values of long-term
debt and capital lease obligations were not materially different from their
carrying amounts.

REVENUE RECOGNITION

     Revenues consist of the sales of palladium and platinum, including any
hedging gain or loss. Byproduct metals revenue and secondary materials
processing revenue are included as a reduction to the cost of metals sold.
Effective January 1, 1997, the company changed its method of revenue recognition
whereby revenue is recognized when product is shipped from the company's base
metals refinery to an external refiner. Sales and receivables are provisionally
valued and later adjusted when sales prices are finalized and weight and assay
calculations are completed. The cumulative effect of this change as of January
1, 1997 was to increase revenue by approximately $2.7 million in the first
quarter of 1997; the effect on net income was not material. Prior to 1997, the
company recognized revenue when product was delivered and transferred to the
buyer.

HEDGING PROGRAM

     The company enters into forward sales contracts and option contracts from
time to time to manage the effect of price changes in palladium and platinum on
the company's sales. The results of these transactions are included in sales
revenue at the same time as the hedged production.

RECLAMATION AND ENVIRONMENTAL COSTS

     Post-closure reclamation and site restoration costs are estimated based on
environmental regulatory requirements and are accrued ratably over the life of
the mine using a units-of-production method.  Current expenditures related to
ongoing environmental and reclamation programs are expensed as incurred,
although the ultimate amount of the obligations to be incurred is uncertain at
December 31, 1998 and 1997, the company has posted $8.9 million in reclamation
bonds for state and federal requirements.  The accrued reclamation liability was
approximately $0.7 million at December 31, 1998 and 1997.

INCOME TAXES

     Income taxes are determined using the asset and liability approach in
accordance with the provisions set forth in SFAS No. 109, Accounting for Income
Taxes.  This method gives consideration to the future tax consequences 

                                       44
<PAGE>
 
of temporary differences between the financial reporting basis and the tax basis
of assets and liabilities based on currently enacted tax rates.

STOCK-BASED COMPENSATION

     The company has adopted the disclosure only provisions of SFAS No. 123,
Accounting for Stock-Based Compensation, and therefore continues to account for
stock options in accordance with Accounting Principles Board (APB) Opinion No.
25, Accounting for Stock Issued to Employees.  Accordingly, because options are
granted at fair market value, no compensation expense has been recognized for
options issued under the company's stock option plans.  The company has made pro
forma disclosures of net income and earnings per share as if the fair value
based method of accounting, as defined in SFAS No. 123, had been applied.

EARNINGS PER SHARE

     The company follows SFAS No. 128, Earnings per Share, which requires the
presentation of basic and diluted earnings per share.

     Basic earnings per share excludes dilution and is computed by dividing net
earnings available to common shareholders by the weighted average number of
common shares outstanding for the period.  Diluted earnings per share reflects
the potential dilution that could occur if securities or other contracts to
issue common stock were exercised or converted into common stock.

                                    NOTE 3
                           NEW ACCOUNTING STANDARDS

     Effective January 1, 1998, the company adopted SFAS No. 130, Reporting
Comprehensive Income.  This statement establishes standards for reporting and
presentation of comprehensive income and its components.

     In June 1998, the Financial Accounting Standards Board (FASB) issued SFAS
No. 133, Accounting for Derivative Instruments and Hedging Activities. This
statement is effective for the fiscal year beginning January 1, 2000 and
establishes accounting and reporting standards for derivative instruments and
hedging activities. The company is currently assessing the impact of this
statement.

     Additionally in June 1998, the American Institute of Certified Public
Accountants issued Statement of Position (SOP) 98-5, Reporting on the Costs of
Start-up Activities.  SOP 98-5 is effective for fiscal year 1999 and requires
that the costs of start-up activities be expensed as incurred.  The company
believes that the effect of this statement on the company's financial statements
will not be material.

SPECIAL INDUSTRIAL EDUCATION IMPACT REVENUE BONDS

     These bonds were issued by the company in 1989 in three series to finance
impact payments to local school districts.  The bonds bear interest at varying
rates between 6.5% and 7.8% and mature in increasing annual principal amounts
through 2009.  The balance outstanding at December 31, 1998 and 1997 was $1.3
million and $1.6 million, respectively, of which approximately $0.1 million was
classified as current in each year.  The bonds, which are collateralized by the
company's real estate, are secured by guarantees from Chevron Corporation and
Manville Corporation.  Scheduled principal repayments during the years 1999
through 2003 are approximately $0.1 million in each year.  Scheduled principal
repayments subsequent to 2003 total $0.9 million.

CONVERTIBLE SUBORDINATED NOTES

     In April 1996, the company sold $51.5 million of 7% Convertible
Subordinated Notes (the "Convertible Notes"), maturing on May 1, 2003. The
Convertible Notes are unsecured, subordinated obligations. As of December 31,
1998 and 1997, $51.4 and $51.5 million were classified as long-term debt,
respectively.

     The Convertible Notes are convertible into shares of common stock on or
before May 1, 1999, unless previously redeemed, at a conversion price of $17.87
per share as adjusted to reflect the three-for-two stock split ($26.80 per share
at original issuance). The company is required to make semi-annual interest
payments. The Convertible Notes are redeemable at the option of the company on
or after May 1, 1999, having no other funding requirements until maturity.

     In connection with the offering of the Convertible Notes, the company filed
a shelf registration statement on Form S-3 under the Securities Act of 1933, as
amended, relating to the resale of the Convertible Notes and the common stock
issuable upon conversion. This registration statement was declared effective by
the Securities and Exchange Commission on December 19, 1996.

     The company made cash payments for interest expense of $4.6, $3.3 and $0.8
million for the years ended December 31, 1998, 1997 and 1996, respectively.

EQUIPMENT LEASE AGREEMENTS

     During 1997, pursuant to the terms of the 1995 Senstar Capital Corporation
Master Lease Agreement, the company entered into its fifth five-year equipment
leasing agreement for $0.8 million.  This agreement was preceded by a $7.5
million leasing agreement with Senstar, signed in October 1995, and by three
additional agreements executed in 1996 totaling $3.8 million.  The latest
contract brings the total capitalized lease transactions with Senstar to $12.1
million.  These agreements cover new underground mining equipment and each
contains a two-year renewal option that can be exercised at the end of five
years.  Based upon the provisions of the leasing agreement, all leases are
capital leases, and the renewal options qualify as extensions of the base lease
term.  As a result, all leased equipment has been capitalized and is being
depreciated over seven years.  Future minimum payments under the equipment
leases are as follows (in thousands):

ROTHSCHILD CREDIT AGREEMENT

     As of April 19, 1994, the company established an unsecured working capital
line of credit with N M Rothschild & Sons Limited, having a maximum borrowing
capacity of $15 million, subject to a borrowing base computation.  The line of
credit is scheduled to expire on April 30, 1999.  Interest on amounts drawn is
payable at 

                                       47
<PAGE>
 
1.5% per annum over the prevailing London Interbank Offered Rate or 0.5% over
the prevailing prime rate. Fees of 1.5% per annum are levied on the aggregate
amount of any letters of credit issued under the facility and a commitment fee
of 0.5% per annum is payable on available but unused amounts. These fees were
$0.1 million in 1998, 1997 and 1996. As of December 31, 1998, the company has
approximately $9.3 million available, is in compliance with all financial
covenants and has no debt outstanding under this facility. This facility will be
cancelled concurrent with completion of the credit facility with the Bank of
Nova Scotia.

SCOTIABANK CREDIT FACILITY

     The company has a commitment for a $175 million credit facility with the
Bank of Nova Scotia ("the Scotiabank Credit Facility"). The Scotiabank Credit
Facility provides for a $125 million term loan facility and a $50 million
revolving credit facility. The Scotiabank Credit Facility is expected to mature
on December 31, 2005. Proceeds of the term loan facility will be used to finance
a portion of the company's development of the East Boulder project, Stillwater
Mine expansion and processing facilities expansion (1998 Expansion Plan).
Proceeds of the revolving credit facility will be used for general corporate and
working capital needs. At the company's option, the Scotiabank Credit Facility
will bear interest at LIBOR or an alternate base rate, in each case plus a
margin of 1.00% to 1.75% which may be adjusted depending upon the company's
ratio of debt to operating cash flow. Substantially all the property and assets
of the company and its subsidiaries and the stock of the company's subsidiaries
will be pledged as security for the Scotiabank Credit Facility. The commitment
is also subject to numerous operating, financial and reporting covenants
customary for agreements of this type.

                            EMPLOYEE BENEFIT PLANS

     On June 1, 1993, the company established the Stillwater Mining Company
401(k) Plan and Trust (the "existing plan"). From June 1, 1993 through September
30, 1996, all eligible employees could participate in this plan. On October 1,
1996, the company established the Stillwater Mining Company 401(k) Plan and
Trust for Bargaining Unit Employees ("the new plan"). All bargaining unit
employees' assets were transferred to the new plan, while all non-bargaining
unit employees continue participation under the existing plan. Employees of the
company with at least six months of consecutive service are eligible to
participate in their respective plan. Other than the differentiation between
bargaining unit employees and non-bargaining unit employees, the plans are
identical. The company matches employee contributions at a 2:1 ratio up to 3% of
the employee's gross wages. Both plans have a three-year cliff vesting period.
Monthly contributions are made to separate trust funds administered by an
independent investment manager. Total plan expenses charged to operations were
$1.2 million, $1.0 million and $0.9 million in 1998, 1997 and 1996,
respectively.

                COMMON AND PREFERRED STOCK PLANS AND AGREEMENTS

STOCK PLAN

     The company sponsors the stock option plans that enable the company to
grant stock options or restricted stock to employees, non-employee directors and
consultants. There are 4,050,000 shares of common stock authorized for issuance
under the plans.

     Awards granted under the plans may consist of either incentive stock
options (ISO) or non-qualified stock options (NSO), stock appreciation rights
(SAR), restricted stock, or other stock-based awards, with the exception that
non-employee directors may not be granted SARs and only employees of the company
may be granted ISOs.

     The plans are administered by the Compensation Committee of the company's
Board of Directors, which determines the exercise price, exercise period,
vesting period and all other terms. Unexercised options expire ten years after
the date of grant.

     There are approximately 784,000 shares available for grant as of December
31, 1998. Stock option activity for the years ended December 31, 1998, 1997 and
1996 is summarized as follows:

     The company has elected to follow APB Opinion No. 25, Accounting for Stock
Issued to Employees, and related interpretations in accounting for its stock
options because, as discussed below, the alternative fair value accounting
provided for under SFAS No. 123, Accounting for Stock-Based Compensation
requires use of option valuation models that were not developed for use in
valuing employee stock options. Under APB No. 25, because the exercise price of
the company's stock options equals the market price of the underlying stock on
the date of grant, no compensation expense is recognized.

     Pro forma information regarding net earnings and earnings per share is
required by SFAS 123, and has been determined as if the company had accounted
for its stock options under the fair value method of SFAS 123. The fair value
for these options was estimated at the date of grant using a Black-Scholes
option pricing model with the following weighted-average assumptions:

   Option valuation models require the input of highly subjective assumptions
including the expected stock price volatility. Because the company's stock
options have characteristics significantly different from those of traded
options, and because changes in the subjective input assumptions can materially
affect the fair value estimate, in management's opinion, the existing models do
not necessarily provide a reliable single measure of the fair value of its stock
options.

     For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. The company's
pro forma information follows (in thousands, except for per share amounts):

     Additionally, 9,950 shares and 30,000 shares of restricted stock were
granted in 1997 and 1994, respectively. Deferred compensation related to
restricted stock was recorded as a component of paid-in capital and is amortized
over the two-year vesting period.

     Outstanding options to purchase 1,938,607, -0- and -0- shares of common
stock were included in the computation of diluted earnings per share for the
years ended December 31, 1998, 1997 and 1996, respectively. Outstanding options
to purchase 264,111, 1,220,549 and 1,005,805 shares of common stock were
excluded from the computation of diluted earnings per share for the years ended
December 31, 1998, 1997 and 1996, respectively, because the effect of inclusion
would have been antidilutive using the treasury stock method.

     In addition, 2,878,656 million shares (1,919,104 million prior to stock
split) of common stock issuable under the terms of the company's Convertible
Subordinated Notes were excluded from the computation of diluted earnings per

effect of inclusion would have been antidilutive using the treasury stock
method. 



SHAREHOLDERS' RIGHTS AGREEMENT

     In October 1995, the Board of Directors of the company adopted a Rights
Agreement under which Stillwater shareholders of record as of November 15, 1995
received a dividend in the form of Preferred Stock Purchase Rights (the
"Rights"). The Rights permit the holder to purchase one one-thousandth of a
share (a unit) of Series A Preferred Stock, par value $0.01 per share (the
"Preferred Stock"), at a purchase price of $80 per unit, subject to adjustment.
All outstanding Rights may be redeemed by the company at any time until such
time the Rights become exercisable. Until a Right is exercised, the holder
thereof has no rights as a shareholder of the company, including the right to
vote or receive dividends. Subject to certain conditions, the Rights become
exercisable ten business days after a person or group acquires or commences a
tender or exchange offer to acquire a beneficial ownership of 15% or more of the
company's outstanding common stock. The Rights expire on October 26, 2005 unless
earlier redeemed or exercised.

     At December 31, 1998, the company had approximately $69.9 million of
regular tax net operating loss carryforwards expiring during 2009 through 2018.
The company made cash payments of $316,000, $0 and $0 for the years ended
December 31, 1998, 1997 and 1996, respectively.

                             CAPITAL TRANSACTIONS

COMMON STOCK OFFERING

    On October 20, 1998, 2,000,000 shares of the company's common stock were
sold under the company's existing $200 million universal shelf registration
statement, which was declared effective by the Securities and Exchange
Commission (SEC) on July 17, 1998. On November 4, 1998, 300,000 additional
shares were sold pursuant to the underwriter's over-allotment option. The $66.6
million of net proceeds will be used to finance a portion of the costs of the
company's expansion plan.

COMMON STOCK SPLIT

    On December 8, 1998, the Board of Directors declared a three-for-two stock
split on the company's common stock effected in the form of a stock dividend to
shareholders of record on December 21, 1998. This stock split was recorded as of
the close of business on December 31, 1998 by transferring par value of $115,158
from additional paid in capital to common stock. All per share data, including
stock option information, have been restated to reflect this stock split.

                             COMMODITY INSTRUMENTS

     The company may use forward sales or other commodity instruments to manage
its exposure to market risk from changes in palladium and platinum commodity
prices. The company may also lease metal to counterparties to earn interest on
excess metal balances.

     As of December 31, 1998, the company had 9,550 ounces of its December
palladium production sold forward for delivery in January 1999 at an average
price of $284 per ounce. At December 31, 1998, the company had 13,100 ounces of
platinum sold forward at an average price of $375 per ounce, with maturities in
1999.

     The company has entered into long-term sales contracts with General Motors
Corporation, Ford Motor Company, Mitsubishi Corporation and KEMET Corp. The
contracts cover the company's production over the five-year period from January
1999 through December 2003. Under the contracts, the company has committed
between 90% to 100% of its palladium production. Palladium sales are priced at a
slight discount to market, with a floor price averaging approximately $225 per
ounce. The company has agreed to an average maximum palladium price of
approximately $400 per ounce on approximately 30% of its production. The
remaining 70% of the company's palladium production is not subject to any price
cap. In addition, the company has committed approximately 20% of its planned
annual platinum production over the next five years. Platinum sales are priced

                                       53
<PAGE>
 
at a slight discount to market, subject to an average minimum price of $350 per
ounce with an average maximum price of $425 per ounce. The remaining 80% of the
company's planned annual platinum production is not committed under these
contracts. Such platinum production remains available for sale at prevailing
market prices. The sales contracts contain termination provisions that allow the
purchasers to terminate in the event the company breaches and the breach is not
cured within periods ranging from ten to thirty days of notice by the purchaser.
In addition, the contracts contain force majeure provisions that allow for the
suspension and, in one instance, the termination of the contract upon the
occurrence of an event of force majeure.

                         COMMITMENTS AND CONTINGENCIES

REFINING AGREEMENTS

     The company has contracted with threefour entities to refine its filter
cake production. Even though there are limited number of PGM refiners, the
company is not economically dependent upon any one refiner.

OPERATING LEASES

     In September 1998, the company completed the sale and leaseback of a tunnel
boring machine and miscellaneous other mining equipment. The leases are
classified as operating leases for financial reporting purposes and are
non-cancelable with terms of seven years. Rental/lease expense, including all
leases, amounted to approximately $0.1 million in 1998. Rental expense in prior
years was insignificant.

     Future minimum lease payments for non-cancelable leases with terms in
excess of one year are $1.6 million in each of the years 1999 - 2003, and $2.7
million thereafter.

SIGNIFICANT CUSTOMERS

     Sales to significant customers represented approximately 60%, 90% and 98%
of total revenues for the years ended December 31, 1998, 1997 and 1996,
respectively. The company sells its metals to a small number of customers and
brokers; however, the company is not economically dependent upon these customers
since palladium and platinum can be readily sold in numerous markets throughout
the world.

ELECTRIC SERVICE AGREEMENT

   During 1996, Montana Power Company (MPC) upgraded the company's transmission
line and substation facilities. The cost of this upgrade to MPC totaled
approximately $2.9 million. In a contract between MPC and the company, the
company agrees to reimburse MPC for these costs through additional electric
revenues produced from the company's increased load in excess of 8,000
kilowatts. At the completion of the five-year agreement, if the total additional
revenues, as defined in the contract between MPC and the company, has not met or
exceeded MPC's investment cost, the company will be required to pay MPC the
difference.

    as of December 31, 1998, 1997, December 31, 1995 and July 1, 1992 and

    in reserves can be attributed to additional drilling and development, the
    use of a lower cut-off grade and adjustment for historical mining
    experience.

Rate Loans (in the absence of delivery of a Continuation/Conversion Notice with
respect to any LIBO Rate Loan at least three Business Days (but not more than
five Business Days) before the last day of the then current Interest Period with
respect thereto, such LIBO Rate Loan shall, on such last day, automatically

LIBO Rate Loan shall nevertheless be to such Lender for the account of such
foreign branch, Affiliate or international banking facility.  In addition, the
Borrower hereby consents and agrees that, for purposes of any determination to
be made for purposes of Section 4.1, 4.2, 4.3 or 4.4, it shall be conclusively

Revolving Loans, be responsible for reimbursing promptly (and in any event
within one Business Day), whether or not any Default shall have occurred and be
continuing, the Issuer for Reimbursement Obligations 

                                      -40-

In addition, such Revolving Loan Lender shall, to the extent of its Percentage
to make Revolving Loans, be entitled to receive a ratable portion of the Letter
of Credit fees payable pursuant to Section 3.3.3 with respect to each Letter of
                                   -------------
Credit (other than the issuance fees payable to an Issuer of such Letter of
Credit pursuant to the last sentence of Section 3.3.3) and of interest payable
                                        -------------

any amounts subsequently received (from the Borrower or otherwise) in respect of
such Disbursement.

beneficiary (or its designee) of such Letter of Credit.  Prior to 11:00 a.m.,
New York time, on the first Business Day following the Disbursement Date, the
Borrower will reimburse the Administrative Agent, for the account of the
applicable Issuer, for all amounts which such Issuer has disbursed under such
Letter of Credit, together with interest thereon at a rate per annum equal to
the rate per annum then in effect for Base Rate Loans (with the then Applicable
Margin for Revolving Loans accruing on such amount) pursuant to Section 3.2 for

the period from the Disbursement Date through the date of such reimbursement.
Without limiting in any way the foregoing and notwithstanding anything to the
contrary contained herein or in any separate application for any Letter of
Credit, the Borrower hereby acknowledges and agrees that it shall be obligated
to reimburse the applicable Issuer upon each Disbursement of a Letter of Credit,
and it shall be deemed to be the obligor for purposes of each such Letter of
Credit issued hereunder (whether the account party on such Letter of Credit is
the Borrower or a Subsidiary).

     SECTION  2.6.3  Reimbursement.  The obligation  (a "Reimbursement
                     -------------                       -------------

under Section 2.6.1 to reimburse an Issuer, shall be absolute and unconditional
      -------------                                                            
under any and all circumstances and irrespective of any setoff, counterclaim or
defense to payment which the Borrower or such Revolving Loan Lender, as the case
may be, may have or have had against such Issuer or any Lender, including any
defense based upon the failure of any Disbursement to conform to the terms of
the applicable Letter of Credit (if, in such Issuer's good faith opinion, such
Disbursement is determined to be appropriate) or any non-application or
misapplication by the beneficiary of the proceeds of such Letter of Credit;
provided, however, that after paying in full its Reimbursement Obligation
- --------  -------                                                        
hereunder, nothing herein shall adversely affect the right of the Borrower or

for any wrongful Disbursement made by such Issuer under a Letter of Credit as a
result of acts or omissions constituting gross negligence or wilful misconduct
on the part of such Issuer.

Administrative Agent (acting at the direction of the Required Lenders) to the
Borrower of its obligations under this Section, following the occurrence and

          (a)  the aggregate Stated Amount of all Letters of Credit shall,
     without demand upon or notice to the Borrower or any other Person, be
     deemed to have been paid or disbursed by the Issuers of such Letters of
     Credit (notwithstanding that such amount may not in fact have been paid or
     disbursed); and

          (b)  the Borrower shall be immediately obligated to reimburse the
     Issuers for the amount deemed to have been so paid or disbursed by such
     Issuers.

Amounts payable by the Borrower pursuant to this Section shall be deposited in
immediately available funds with the Administrative Agent and held as collateral
security for the Reimbursement Obligations.  When all Defaults giving rise to
the deemed disbursements under this Section have been cured or waived the
Administrative Agent shall return to the Borrower all amounts then on deposit
with the Administrative Agent pursuant to this Section which have not been
applied to the satisfaction of the Reimbursement Obligations.

     SECTION  2.6.5  Nature of Reimbursement Obligations.  The Borrower, each
                     -----------------------------------

Lender shall assume all risks of the acts, omissions or misuse of any Letter of
Credit by the beneficiary thereof.  No Issuer (except to the extent of its own
gross negligence or wilful misconduct) shall be responsible for:

          (a)  the form, validity, sufficiency, accuracy, genuineness or legal
     effect of any Letter of Credit or any document submitted by any party in
     connection with the application for and issuance of a Letter of Credit,
     even if it should in fact prove to be in any or all respects invalid,
     insufficient, inaccurate, fraudulent or forged;

          (b)  the form, validity, sufficiency, accuracy, genuineness or legal
     effect of any instrument transferring or assigning or purporting to
     transfer or assign a Letter of Credit or the rights or benefits thereunder
     or the proceeds thereof in whole or in part, which may prove to be invalid
     or ineffective for any reason;

          (c)  failure of the beneficiary to comply fully with conditions
     required in order to demand payment under a Letter of Credit;

          (d)  errors, omissions, interruptions or delays in transmission or
     delivery of any messages, by mail, cable, telegraph, telex or otherwise; or

     document or draft required in order to make a Disbursement under a Letter
     of Credit.

None of the foregoing shall affect, impair or prevent the vesting of any of the
rights or powers granted to any Issuer or any Revolving Loan Lender hereunder.
In furtherance and not in limitation or derogation of any of the foregoing, any
action taken or omitted to be taken by an Issuer in good faith (and not
constituting gross negligence or willful misconduct) shall be binding upon each
Obligor and each such Secured Party, and shall not put such Issuer under any
resulting liability to any Obligor or any Secured Party, as the case may be.

accordance with its usual practice an account or accounts evidencing the
Indebtedness of the Borrower to such Lender resulting from each Loan made by
such Lender, including the amounts of principal and interest payable and paid to
such Lender from time to time hereunder.  In the case of a Lender that does not
request, pursuant to clause (b) below, execution and delivery of a Note
                     ----------                                        
evidencing the Loans made by such Lender to the Borrower, such account or
accounts shall, to the extent not inconsistent with the notations made by the
Administrative Agent in the Register, be conclusive and binding on the Borrower
absent manifest error; provided, however, that the failure of any Lender to

Obligations of the Borrower or any other Obligor.

     (b)  The Borrower agrees that, upon the request to the Administrative Agent
by any Lender, the Borrower will promptly execute and deliver to such Lender, as
applicable, a Note evidencing the Loans made by such Lender.  The Borrower
hereby irrevocably authorizes each Lender to make (or cause to be made)
appropriate notations on the grid attached to such Lender's Notes (or on any
continuation of such grid), which notations, if made, shall evidence, inter
                                                                      -----

and Interest Period applicable to the Loans evidenced thereby.  Such notations
shall, to the extent not inconsistent with the notations made by the
Administrative Agent in the Register, be conclusive and binding on the Borrower
absent manifest error; provided, however, that the failure of any Lender to make
                       --------  -------                                        
any such notations shall not limit or otherwise affect any Obligations of the
Borrower or any other Obligor.

continue any Loans as, or to convert any Loans into, LIBO Rate Loans shall
forthwith be suspended until the Administrative Agent shall notify the Borrower
and the Lenders that the circumstances causing such suspension no longer exist.

     SECTION  4.3  Increased LIBO Rate Loan Costs, etc.  The Borrower agrees to
                   -----------------------------------                         
reimburse each Lender and Issuer for any increase in the cost to such Lender or
Issuer of, or any reduction in the amount of any sum receivable by such Secured
Party in respect of, such Secured Party's Commitments and the making of Credit
Extensions hereunder (including the making, continuing or maintaining (or of its
obligation to make, continue or maintain) any Loans as, or of converting (or of
its obligation to convert) any Loans into, LIBO Rate Loans) that arise in
connection with any change in, or the introduction, adoption, effectiveness,
interpretation, reinterpretation or phase-in after the date hereof of, any law
or regulation, directive, guideline, decision or request (whether or not having
the force of law) of any Governmental Authority, except for such changes with
respect to increased capital costs and Taxes which are governed by Sections 4.5
                                                                   ------------
and 4.6, respectively.  Each affected Secured Party shall promptly notify the
    ---                                                                      
Administrative Agent and the Borrower in writing of the occurrence of any such
event, such notice to state the reasons therefor and the additional amount
required fully to compensate such Secured Party for such increased cost or
reduced amount.  Such additional amounts shall be payable by the Borrower
directly to such Secured Party within five days of its receipt of such notice,
and such notice shall, in the absence of manifest error, be conclusive and
binding on the Borrower.

     SECTION  4.4  Funding Losses.  In the event any Lender shall incur any loss
                   --------------                                               
or expense (including any loss or expense incurred by reason of the liquidation
or reemployment of deposits or other funds acquired by such Lender to make or
continue any portion of the principal amount of any Loan as, or to convert any
portion of the principal amount of any Loan into, a LIBO Rate Loan) as a result
of

          (a)  any conversion or repayment or prepayment of the principal amount
     of any LIBO Rate Loan on a date other than the scheduled last day of the
     Interest Period applicable thereto, whether pursuant to Article III or
                                                             -----------   
     otherwise;

          (b)  any Loans not being made as LIBO Rate Loans in accordance with
     the Borrowing Request therefor; or

                                      -49-

<PAGE>
 
          (c)  any Loans not being continued as, or converted into, LIBO Rate
     Loans in accordance with the Continuation/Conversion Notice therefor;

then, upon the written notice of such Lender to the Borrower (with a copy to the
Administrative Agent), the Borrower shall, within five days of its receipt
thereof, pay directly to such Lender such amount as will (in the reasonable
determination of such Lender) reimburse such Lender for such loss or expense.
With such notice, the Lender shall provide the Borrower with a certificate
outlining in reasonable detail the computations of any amounts claimed and the
assumptions underlying such computations.  Such written notice shall, in the
absence of manifest error, be conclusive and binding on the Borrower. The
Borrower shall have no obligation to make a payment under this Section to a
Secured Party unless such Lender shall have notified the Borrower of its demand
therefor within 60 days of the date on which such Lender has obtained final
internal financial statements with respect to the Fiscal Quarter of such Lender
in which such loss or expense occurred.

     SECTION  4.5  Increased Capital Costs.  If any change in, or the
                   -----------------------                           
introduction, adoption, effectiveness, interpretation, reinterpretation or
phase-in of, any law or regulation, directive, guideline, decision or request
(whether or not having the force of law) of any Governmental Authority affects
or would affect the amount of capital required or expected to be maintained by
any Secured Party or any Person controlling such Secured Party, and such Secured
Party determines (in good faith but in its sole and absolute discretion) that
the rate of return on its or such controlling Person's capital as a consequence
of the Commitments or the Credit Extensions made, or the Letters of Credit
participated in, by such Secured Party is reduced to a level below that which
such Secured Party or such controlling Person could have achieved but for the
occurrence of any such circumstance, then, in any such case upon notice from
time to time by such Secured Party to the Borrower, the Borrower shall within
five days following receipt of such notice pay directly to such Secured Party
additional amounts sufficient to compensate such Secured Party or such
controlling Person for such reduction in rate of return.  With such notice, the
Secured Party shall provide the Borrower with a certificate outlining in
reasonable detail the computations of any amounts claimed and the assumptions
underlying such computations. A statement of such Secured Party as to any such
additional amount or amounts shall, in the absence of manifest error, be
conclusive and binding on the Borrower.  In determining such amount, such
Secured Party may use any method of averaging and attribution that it (in its
sole and absolute discretion) shall deem applicable.  The Borrower shall have no
obligation to make a payment under this Section to a Secured Party unless such
Secured Party shall have notified the Borrower of its demand therefor within 60
days of the date on which such Secured Party has obtained final internal
financial statements with respect to the Fiscal Quarter of such Secured Party as
to which such additional amount or amounts are being claimed.

     SECTION  4.6  Taxes.  The Borrower covenants and agrees as follows with
                   -----                                                    
respect to Taxes.

          (a)  Any and all payments by the Borrower under this Agreement and
     each other Loan Document shall be made without setoff, counterclaim or
     other defense, and free and 

                                      -50-

<PAGE>
 
     clear of, and without deduction or withholding for or on account of, any
     Taxes. In the event that any Taxes are required by law to be deducted or
     withheld from any payment required to be made by the Borrower to or on
     behalf of any Secured Party under any Loan Document, then:

               (i)  subject to clause (f), if such Taxes are Non-Excluded Taxes,
                               ----------                                       
          the amount of such payment shall be increased as may be necessary such
          that such payment is made, after withholding or deduction for or on
          account of such Taxes, in an amount that is not less than the amount
          provided for herein or in such other Loan Document; and

               (ii)  the Borrower shall withhold the full amount of such Taxes
          from such payment (as increased pursuant to clause (a)(i)) and shall
                                                      -------------           
          pay such amount to the Governmental Authority imposing such Taxes in
          accordance with applicable law.

          (b)  In addition, the Borrower shall pay any and all Other Taxes
     imposed to the relevant Governmental Authority imposing such Other Taxes in
     accordance with applicable law.

          (c)  As promptly as practicable after the payment of any Taxes or
     Other Taxes, and in any event within 45 days of any such payment being due,
     the Borrower shall furnish to the Administrative Agent a copy of an
     official receipt (or a certified copy thereof) evidencing the payment of
     such Taxes or Other Taxes.  The Administrative Agent shall make copies
     thereof available to any Lender upon request therefor.

          (d)  Subject to clause (f), the Borrower shall indemnify each Secured
                          ----------                                           
     Party for any Non-Excluded Taxes and Other Taxes levied, imposed or
     assessed on (and whether or not paid directly by) such Secured Party
     (whether or not such Non-Excluded Taxes or Other Taxes are correctly or
     legally asserted by the relevant Governmental Authority). Promptly upon
     having knowledge that any such Non-Excluded Taxes or Other Taxes have been
     levied, imposed or assessed, and promptly upon notice thereof by any
     Secured Party, the Borrower shall pay such Non-Excluded Taxes or Other
     Taxes directly to the relevant Governmental Authority (provided, however,
                                                            --------  ------- 
     that no Secured Party shall be under any obligation to provide any such
     notice to the Borrower).   In addition, the Borrower shall indemnify each
     Secured Party for any incremental Taxes that may become payable by such
     Secured Party as a result of any failure of the Borrower to pay any Taxes
     when due to the appropriate Governmental Authority or to deliver to the
     Administrative Agent, pursuant to clause (c), documentation evidencing the
                                       ----------                              
     payment of Taxes or Other Taxes.  With respect to indemnification for Non-
     Excluded Taxes and Other Taxes actually paid by any Secured Party or the
     indemnification provided in the immediately preceding sentence, such
     indemnification shall be made within 30 days after the date such Secured
     Party makes written demand therefor.  The Borrower acknowledges that any
     payment made to any Secured Party or to any Governmental 

                                      -51-

     Authority in respect of the indemnification obligations of the Borrower
     provided in this clause shall constitute a payment in respect of which the
     provisions of clause (a) and this clause shall apply.

          (e)  Each Non-U.S. Lender, on or prior to the date on which such Non-
     U.S. Lender becomes a Lender hereunder (and from time to time thereafter
     upon the request of the Borrower or the Administrative Agent, but only for
     so long as such Non-U.S. Lender is legally entitled to do so), shall
     deliver to the Borrower and the Administrative Agent either

               (i)  (x) two duly completed copies of either (A) Internal Revenue
          Service Form 1001 (if delivered on or prior to December 31, 1999) or

          Form 4224 (if delivered on or prior to December 31, 1999) or Internal
          Revenue Services Form W-8ECI, or in any such case an applicable
          successor form, and (y) a duly completed copy of Internal Revenue
          Service Form W-8 or W-9 (for periods prior to January 1, 2000) or
          applicable successor form; or

               (ii)  in the case of a Non-U.S. Lender that is not legally
          entitled to deliver either form listed in clause (e)(i)(x), (x) a
                                                    ----------------       
          certificate of a duly authorized officer of such Non-U.S. Lender to
          the effect that such Non-U.S. Lender is not (A) a "bank" within the
          meaning of Section 881(c)(3)(A) of the Code, (B) a "10 percent
          shareholder" of the Borrower within the meaning of Section
          881(c)(3)(B) of the Code, or (C) a controlled foreign corporation
          receiving interest from a related person within the meaning of Section
          881(c)(3)(C) of the Code (such certificate, an "Exemption

          Certificate") and (y) two duly completed copies of Internal Revenue
          Service Form W-8 or applicable successor form.

          (f)  The Borrower shall not be obligated to gross up any payments to
     any Lender pursuant to clause (a)(i), or to indemnify any Lender pursuant
                            -------------

     the Borrower the form or forms and/or an Exemption Certificate, as
     applicable to such Lender, pursuant to clause (e), (ii) such form or forms

     and/or Exemption Certificate not establishing a complete exemption from
     U.S. federal withholding tax or the information or certifications made
     therein by the Lender being untrue or inaccurate on the date delivered in
     any material respect, or (iii) the Lender designating a successor lending
     office at which it maintains its Loans which has the effect of causing such
     Lender to become obligated for tax payments in excess of those in effect
     immediately prior to such designation; provided, however, that the Borrower

     untruth contained therein resulted from a change in any applicable statute,
     treaty, regulation or other applicable law or any interpretation of any of
     the foregoing occurring after the date hereof, which change rendered such
     Lender no longer legally entitled to deliver such form or forms or
     Exemption Certificate or otherwise ineligible for a complete exemption from
     U.S. federal withholding tax, or rendered the information or certifications
     made in such form or forms or Exemption Certificate untrue or inaccurate in
     a material respect, (ii) the redesignation of the Lender's lending office
     was made at the request of the Borrower or (iii) the obligation to gross up

     SECTION  4.7  Payments, Computations, etc.  Unless otherwise expressly
                   ---------------------------

receive such payment.  All such payments required to be made to the
Administrative Agent shall be made, without setoff, deduction or counterclaim,
not later than 11:00 a.m., New York time, on the date due, in same day or
immediately available funds, to such account as the Administrative Agent shall
specify from time to time by notice to the Borrower. Funds received after that
time shall be deemed to have been received by the Administrative Agent on the
next succeeding Business Day.  The Administrative Agent shall promptly remit in
same day funds to each Secured Party its share, if any, of such payments
received by the Administrative Agent for the account of such Secured Party.  All
interest (including interest on LIBO Rate Loans) and fees shall be computed on
the basis of the actual number of days (including the first day but excluding
the last day) occurring during the period for which such interest or fee is
payable over a year comprised of 360 days (or, in the case of interest on a Base
Rate Loan (calculated at other than the Federal Funds Rate), 365 days or, if
appropriate, 366 days).  Whenever any payment to be made shall otherwise be due
on a day which is not a Business Day, such payment shall (except as otherwise
required by clause (c) of the definition of the term "Interest Period") be made
            ----------

setoff or otherwise) on account of any Credit Extension or Reimbursement
Obligation (other than pursuant to the terms of Section 4.3, 4.4, 4.5 or 4.6) in

Secured Party shall purchase from the other Secured Parties such participations
in Credit Extensions made by them as shall be necessary to cause such purchasing
Secured Party to share the excess payment or other recovery ratably (to the
extent such other Secured Parties were entitled to receive a portion of such
payment or recovery) with each of them; provided, however, that if all or any
                                        --------  -------                    
portion of the excess payment or other recovery is thereafter recovered from
such purchasing Secured Party, the purchase shall be rescinded and each Secured
Party which 

                                      -53-

<PAGE>
 
has sold a participation to the purchasing Secured Party shall repay to the
purchasing Secured Party the purchase price to the ratable extent of such
recovery together with an amount equal to such selling Secured Party's ratable
share (according to the proportion of

          (a)  the amount of such selling Secured Party's required repayment to
     the purchasing Secured Party

to
- --

          (b)  total amount so recovered from the purchasing Secured Party)

of any interest or other amount paid or payable by the purchasing Secured Party
in respect of the total amount so recovered.  The Borrower agrees that any
Secured Party so purchasing a participation from another Secured Party pursuant
to this Section may, to the fullest extent permitted by law, exercise all its
rights of payment (including pursuant to Section 4.9) with respect to such
                                         -----------                      
participation as fully as if such Secured Party were the direct creditor of the
Borrower in the amount of such participation.  If under any applicable
bankruptcy, insolvency or other similar law, any Secured Party receives a
secured claim in lieu of a setoff to which this Section applies, such Secured
Party shall, to the extent practicable, exercise its rights in respect of such
secured claim in a manner consistent with the rights of the Secured Parties
entitled under this Section to share in the benefits of any recovery on such
secured claim.

     SECTION  4.9  Setoff.  Each Secured Party shall, upon the occurrence and
                   ------                                                    
during the continuance of any Default described in clauses (a) through (d) of
                                                   -----------         ---

and during the continuance of any other Event of Default, have the right to
appropriate and apply to the payment of the Obligations owing to it (whether or
not then due), and (as security for such Obligations) the Borrower hereby grants
to each Secured Party a continuing security interest in, any and all balances,
credits, deposits, accounts or moneys of the Borrower then or thereafter
maintained with such Secured Party; provided, however, that any such
                                    --------  -------               
appropriation and application shall be subject to the provisions of Section 4.8.
                                                                    ----------- 
Each Secured Party agrees promptly to notify the Borrower and the Administrative
Agent after any such setoff and application made by such Secured Party;
                                                                       
provided, however, that the failure to give such notice shall not affect the

validity of such setoff and application.  The rights of each Secured Party under
this Section are in addition to other rights and remedies (including other
rights of setoff under applicable law or otherwise) which such Secured Party may
have.

     SECTION  6.15  Year 2000.  Each Obligor has reviewed the areas within its

business and operations which could be adversely affected by, and has developed
or is developing a program to address on a timely basis, the "Year 2000 Problem"
(that is, the risk that computer applications used by such Obligor may be unable
to recognize and properly perform date-sensitive functions involving certain
dates prior to and any date after December 31, 1999). Based on such review and
program, the Year 2000 Problem could not reasonably be expected to have a
Material Adverse Effect.

     SECTION  6.16  Status of Obligations as Senior Indebtedness, etc.  The
                    -------------------------------------------------      
subordination provisions of the Subordinated Debt contained in the Subordinated
Debt Documents are enforceable against the holders of the Subordinated Debt by
the holder of any "Senior Debt" or similar term referring to the Obligations (as
defined in the relevant Subordinated Debt Documents).  All Obligations,
including those to pay principal of and interest (including post-petition
interest, whether or not allowed as a claim under bankruptcy or similar laws) on
the Loans and Reimbursement Obligations, and fees and expenses in connection
therewith, constitute "Senior Debt" and "Designated Senior Debt" or similar
terms relating to the Obligations (as defined in the relevant Subordinated Debt
Documents) and all such Obligations are entitled to the benefits of the
subordination created by the Subordinated Debt Documents.  In furtherance of,
and without limiting the effect of, the preceding sentence of this Section 6.16,
                                                                   ------------ 
all such Obligations constitute "Senior Debt" and "Designated Senior Debt" under
the Convertible Subordinated Note Indenture (and such Obligations are hereby
designated by the Borrower as "Designated Senior Debt" for all purposes under
the Convertible Subordinated Note Indenture with no limitation on the rights
that may be exercised by the holders of such Designated Senior Debt). The
Borrower acknowledges that the Administrative Agent, each Lender and each Issuer
is entering into this Agreement and is extending its Commitments in reliance
upon the subordination provisions of the Subordinated Debt Documents.

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

rights, water rights, plant sites, tailings disposal, waste dumps, ore dumps,
abandoned heaps or ancillary facilities which are required in connection with
the Project.  All such Mining Rights and other rights are sufficient in scope
and substance for the development of the Project as contemplated by the Mine
Plans and no part of the purchase price payable in connection with the
acquisition of such Mining Rights and other rights (other than royalty payments,
if any, described in Item 6.17 of Disclosure Schedule) remain unpaid.  All
                     ---------

     Borrower or its Subsidiaries. Such insurance shall contain all standard
     extensions customary for such policy and a waiver by the insurer of

     in respect of all vehicles (whether owned, hired or rented by such Person)
     at any time located at, or used in connection with, the property owned or
     operated by the Borrower or its Subsidiaries in such amounts as are then
     customary for vehicles used in connection with similar properties and
     businesses and to the extent required by law, but in no event less than the
     Applicable AL Threshold (as defined below) per accident.  Such insurance
     shall contain a waiver by the insurer of subrogation rights against the
     Borrower.  For purposes of this paragraph, "Applicable AL Threshold" means

     (i) with respect to any Person described in Part B of Schedule V attached
                                                 ------    ----------

     respect to any other Person, $2,000,000.

     (c)  Third Party Engineering/Design Insurance. The Borrower will ensure
          ----------------------------------------                          
that each Person contracted by the Borrower or any of its Subsidiaries to
perform engineering and/or design or related services with respect to the
Project maintains at a minimum professional liability insurance relating to
errors and omissions in an amount not less than the Applicable Professional
Threshold (as defined below) in the aggregate per such Person covering a period
until Project Completion plus, to the extent commercially practicable, an
additional period of four years from Project Completion.  For purposes of this
paragraph, "Applicable Professional Threshold" means (i) with respect to any
            ---------------------------------                               
Person described in Part C of Schedule V attached hereto, the amount set forth
                    ------    ----------                                      
opposite such Person's name and (ii) with respect to any other Person,
$2,000,000.

All such insurance shall be written by financially responsible companies
selected by the Borrower and (except for automobile insurance) having an A.M.
Best rating of "A" or better and being in a financial size category of VII or
larger (or an equivalent rating of any successor publication of a similar
nature), or by other companies acceptable to the Administrative Agent, and
(other than workers' compensation) shall name the Administrative Agent as loss
payee (to the extent covering risk of loss or damage to tangible property) and
as an additional named insured as its interests may appear (to the extent
covering any other risk).  Each policy referred to in this Section 7.1.4 shall
                                                           -------------      
provide that it will not be canceled or reduced, or allowed to lapse without
renewal, except after not less than 30 days' notice to the Administrative Agent
and shall 

                                      -76-

<PAGE>
 
also provide that the interests of the Administrative Agent and the Lenders
shall not be invalidated by any act or negligence of the Borrower, any of its
Subsidiaries or any Person having an interest in any property covered by a
Mortgage nor by occupancy or use of any such property for purposes more
hazardous than permitted by such policy nor by any foreclosure or other
proceedings relating to such property. The Borrower will advise the
Administrative Agent promptly of any significant policy cancellation (other than
any such cancellation in connection with the replacement thereof), reduction or
amendment.

     On or before the Closing Date, the Borrower will deliver to the
Administrative Agent certificates of insurance satisfactory to the
Administrative Agent evidencing the existence of all insurance required to be
maintained by the Borrower hereunder setting forth the respective coverages,
limits of liability, carrier, policy number and period of coverage. The Borrower
will not, and will not permit any of its Subsidiaries to, obtain or carry
separate insurance concurrent in form or contributing in the event of loss with
that required by this Section 7.1.4 unless the Administrative Agent is the named
                      -------------                                             
insured thereunder, for the benefit of the Secured Parties, with loss payable as
provided herein.  The Borrower will immediately notify the Administrative Agent
whenever any such separate insurance is obtained and shall deliver to the
Administrative Agent the certificates evidencing the same.

     Without limiting the obligations of the Borrower under the foregoing
provisions of this Section 7.1.4, in the event the Borrower shall fail to
                   -------------                                         
maintain in full force and effect insurance as required by the foregoing
provisions of this Section 7.1.4, then the Administrative Agent may (upon notice
                   -------------                                                
to the Borrower), but shall have no obligation so to do, procure insurance
covering the interests of the Lenders and the Administrative Agent in such
amounts and against such risks as the Administrative Agent (or the Required
Lenders) shall deem appropriate, and the Borrower shall reimburse the
Administrative Agent in respect of any premiums paid by the Administrative Agent
in respect thereof.

     For purposes hereof, the term "Insured Peril" shall mean, collectively, all
                                    -------------                               
risks of physical loss including flood, earthquake and windstorm in the
jurisdictions where the properties owned or operated by the Borrower or any of
its Subsidiaries are located.

     SECTION  7.1.5  Books and Records; Annual Assessment Meeting.  (a) The
                     --------------------------------------------          
Borrower will, and will cause each of its Subsidiaries to, keep books and
records in accordance with GAAP which accurately reflect all of its business
affairs and transactions and permit the Administrative Agent or any of its
representatives, at reasonable times and intervals upon reasonable notice to the
Borrower, to inspect any and all of the properties and operations of the
Borrower (including the Mines) and to visit each Obligor's offices, to discuss
such Obligor's financial matters with its officers and employees and its
independent public accountants (and the Borrower hereby authorizes such
independent public accountant to discuss the Borrower's and each Obligor's
financial matters with the Administrative Agent or its representatives whether
or not any representative of the Borrower or such Obligor is present) and to
examine (and photocopy extracts from) any of its books and records.  The
Borrower shall be afforded an 

                                      -77-

<PAGE>
 
opportunity to be present at, or party to, each such inspection, visit and
discussion, provided that the right of the Administrative Agent and its
            --------
representatives to conduct any such inspection, visit or discussion shall not be
adversely affected by the Borrower's failure to be so present or to be a party
thereto. Unless a Default has occurred and is continuing, the Borrower shall
only be required to pay the costs and expenses incurred in connection with the
Administrative Agent's exercise of its rights pursuant to this Section with
respect to two inspections per calendar year.

     (b)  The Borrower shall also arrange an annual meeting of the Lenders at or
near the East Boulder Mine pursuant to which meeting the Lenders will be given
an opportunity to discuss the progress of the Project and the operations of the
Borrower and its Subsidiaries with the officers and employees of the Borrower,
including an opportunity to visit and inspect the Project site with such
officers and/or employees.  The Borrower shall provide at least 30 days' prior
written notice of such meeting and such meeting shall occur on a Business Day.
Unless a Default has occurred and is continuing, the costs and expenses of a
Lender attending such annual meeting shall be the responsibility of such Lender.

     SECTION  7.1.6  Environmental Law Covenant.  The Borrower will, and will
                     --------------------------                              
cause each of its Subsidiaries to,

          (a)  use and operate all of its and their facilities and properties in
     material compliance with all Environmental Laws, keep, or timely apply for
     renewal of, all necessary permits, approvals, certificates, licenses and
     other authorizations relating to environmental matters and required for
     current operations (including completion of the Project) in effect and
     remain in material compliance therewith, and handle all Hazardous Materials
     in material compliance with all applicable Environmental Laws; and

          (b)  promptly notify the Administrative Agent and provide copies upon
     receipt of all written claims, complaints, notices or inquiries relating to
     the condition of its facilities and properties in respect of, or as to
     compliance with, Environmental Laws, to the extent conditions described in
     such claims, complaints, notices and inquiries could reasonably be expected
     to result in a liability for the Borrower and its Subsidiaries in an
     aggregate amount exceeding $2,500,000 and shall promptly resolve any
     material non-compliance with Environmental Laws and keep its property free
     of any Lien imposed by any Environmental Law.

     SECTION  7.1.7  Use of Proceeds.  The Borrower will apply the proceeds of 
                     ---------------       
the Credit Extensions as follows:

          (a)  the proceeds of Term Loans shall be used to provide for capital
     expenditures related to (i) the expansion of the Nye Mine, (ii) the
     construction of the East Boulder Mine and (iii) expansion of the Borrower's
     processing facilities located in Columbus, Montana; and

                                      -78-

<PAGE>
 
          (b)  the proceeds of Revolving Loans shall be used to provide for the
     general corporate and working capital needs of the Borrower and to pay fees
     and expenses related to the Transaction, including for the issuing of
     Letters of Credit for the account of the Borrower.

     SECTION  7.1.8  Additional Real Property.  The Borrower shall, and shall
                     ------------------------                                
cause each of its Subsidiaries to, cause the Administrative Agent and the
Lenders to have at all times a first priority perfected security interest
(subject only to Permitted Liens) in all of the real property acquired from time
to time by the Borrower and its Subsidiaries (other than any such real property
that, when added to the net book value of all other real property acquired by
the Borrower and its Subsidiaries in the calendar year in which such
determination is being made, has a net book value of less than $1,000,000);
                                                                           
provided, however, that, in the event such real property is owned by a Foreign
- --------  -------                                                             
Subsidiary (other than a Foreign Subsidiary that (i) is treated as a partnership
under the Code or (ii) is not treated as an entity that is separate from (A) the
Borrower, (B) any Person that is treated as a partnership under the Code or (C)
any "United States person" (as defined in Section 7701(a)(30) of the Code)),
such Subsidiary shall not be required to grant such security interest (1) if the
Required Lenders have otherwise agreed or (2) to the extent such grant could
reasonably be expected to constitute at any time an investment of earnings in
United States property under Section 956 (or any successor provision thereto) of
the Code that would increase the amount of United States federal income tax that
would otherwise be payable by the Borrower and the other members of the
affiliated group of corporations filing a consolidated federal income tax return
with the Borrower in the absence of such grant, as determined by the Borrower
based on existing financial statements and on financial projections prepared in
good faith based upon assumptions which the Borrower believes to be reasonable
and as evidenced by a certificate of the chief financial Authorized Officer of
the Borrower that is accepted in writing by the Administrative Agent (such
acceptance not to be unreasonably withheld and which acceptance shall be deemed
to have occurred in the absence of a written notice from the Administrative
Agent that is given to the Borrower within five Business Days of the
Administrative Agent's receipt of such certificate, indicating the reasons for
not accepting such certificate); provided, further, however, that, in the event
                                 --------  -------  -------                    
of any change in, or the introduction, adoption, effectiveness, interpretation,
reinterpretation or phase-in of, any law or regulation, directive or guideline
of any Governmental Authority that could reasonably be expected to alter the
conclusion set forth in such certificate, the Administrative Agent or the
Required Lenders may request the Borrower to deliver another such certificate in
light of such event and, in the absence of the delivery and acceptance of such
certificate as provided above, require the grant of such security interest.
Without limiting the generality of the foregoing, the Borrower shall, and shall
cause each such Subsidiary to, execute and deliver or cause to be executed and
delivered Mortgages, that may be necessary or, in the opinion of the
Administrative Agent, desirable to create a valid, perfected Lien against such
real property, together with

          (a)  evidence of the completion (or satisfactory arrangements for the
     completion) of all recordings and filings of each such Mortgage as may be
     necessary or, in the 

                                      -79-

<PAGE>
 
     reasonable opinion of the Administrative Agent, desirable to create a
     valid, perfected and (subject to Permitted Liens) first priority Lien
     against the properties purported to be covered thereby;

           (b)  (i) mortgagee's title insurance policies with respect to
     property purported to be covered by such Mortgage (except patented and
     unpatented mining claims) in favor of the Administrative Agent for the
     benefit of the Secured Parties in amounts and in form and substance and
     issued by insurers reasonably satisfactory to the Administrative Agent
     addressed to the Administrative Agent and the Lenders, insuring that title
     to such property is marketable and that the interests created by such
     Mortgage constitute valid, perfected first priority Liens thereon free and
     clear of all defects and encumbrances other than as approved by the
     Administrative Agent, and such policies shall also include a survey
     reading, and, if required by the Administrative Agent and if available,
     revolving credit endorsement, comprehensive endorsement, variable rate
     endorsement, access and utilities endorsements, mechanic's lien endorsement
     and such other endorsements as the Administrative Agent shall reasonably
     request and shall be accompanied by evidence of the payment in full of all
     premiums thereon, and (ii)  mortgagee's title opinions with respect to
     patented and unpatented mining claims purported to be covered by such
     Mortgage in favor of the Administrative Agent for the benefit of the
     Secured Parties addressed to the Administrative Agent and the Lenders and
     in form and substance reasonably satisfactory to the Administrative Agent;

          (c)  U.C.C. financing statements related to the security interests
     created by each such Mortgage, together with evidence of the completion (or
     satisfactory arrangements for the completion) of all recordings and filings
     of such financing statements in the appropriate offices and records as may
     be necessary or, in the reasonable opinion of the Administrative Agent,
     desirable to create valid, perfected and (subject to Permitted Liens) first
     priority Liens against the improvements purported to be covered thereby;
     and

          (d)  such other approvals, opinions or documents as the Administrative
     Agent may reasonably request, including a current survey (or, in the case
     of property in respect of a Mine, the most recently completed mineral
     survey) of each property purported to be covered by each such Mortgage in
     form and substance satisfactory to the Administrative Agent and the title
     insurer.

     SECTION  7.1.9  Future Subsidiaries.  Without limiting the effect of any
                     -------------------                                     
provision contained herein (including Section 7.2.5), upon any Person becoming

either a direct or indirect Subsidiary of the Borrower,

          (a)  such Person, if not theretofore a party to a Subsidiary Security
     Agreement and Subsidiary Guaranty, shall execute and deliver to the
     Administrative Agent a Subsidiary Security Agreement and Subsidiary
     Guaranty for the benefit of the Secured Parties; provided, however, that,
                                                      --------  -------       
     in the event such Subsidiary is a Foreign Subsidiary (other than 

                                      -80-

<PAGE>
 
     a Foreign Subsidiary that (i) is treated as a partnership under the Code or
     (ii) is not treated as an entity that is separate from (A) the Borrower,
     (B) any Person that is treated as a partnership under the Code or (C) any
     "United States person" (as defined in Section 7701(a)(30) of the Code)),
     such Subsidiary shall not be required to become a guarantor under
     Subsidiary Guaranty or execute and deliver a Subsidiary Security Agreement
     (1) if the Required Lenders have otherwise agreed or (2) to the extent such
     guaranty could reasonably be expected to constitute at any time an
     investment of earnings in United States property under Section 956 (or any
     successor provision thereto) of the Code that would increase the amount of
     United States federal income tax that would otherwise be payable by the
     Borrower and the other members of the affiliated group of corporations
     filing a consolidated federal income tax return with the Borrower in the
     absence of such guaranty, as determined by the Borrower based on existing
     financial statements and on financial projections prepared in good faith
     based upon assumptions which the Borrower believes to be reasonable and as
     evidenced by a certificate of the chief financial Authorized Officer of the
     Borrower that is accepted in writing by the Administrative Agent (such
     acceptance not to be unreasonably withheld and which acceptance shall be
     deemed to have occurred in the absence of a written notice from the
     Administrative Agent that is given to the Borrower within five Business
     Days of the Administrative Agent's receipt of such certificate, indicating
     the reasons for not accepting such certificate); provided, further,

     that could reasonably be expected to alter the conclusion set forth in such

     the Borrower to deliver another such certificate in light of such event
     and, in the absence of the delivery and acceptance of such certificate as
     provided above, require the execution and delivery by such Person of such
     Subsidiary Guaranty;

     Security Agreement, shall execute and deliver to the Administrative Agent a
     Subsidiary Security Agreement for the purpose of becoming a pledgor
     thereunder), shall, pursuant to the applicable Security Agreement, pledge
     to the Administrative Agent, for the benefit of the Secured Parties, (i)

     uncertificated, confirmation and evidence satisfactory to the
     Administrative Agent that the security interest in such uncertificated
     securities has been perfected by the Administrative Agent in accordance

     and the Administrative Agent as the secured party, suitable for filing
     under the U.C.C. of all jurisdictions as may be necessary or, in the
     reasonable opinion of the Administrative Agent, desirable to perfect the
     security interest of the Administrative Agent in the interests of the
     Borrower or such Subsidiary in such Person pledged pursuant to such
     Security Agreement; provided, however, that the Borrower or such Subsidiary
                         --------  -------
     shall not be required to pledge the shares of Capital Stock of a Foreign
     Subsidiary required to be pledged hereunder (1) if the Required Lenders
     have otherwise agreed or (2) to the extent such pledge could reasonably be
     expected to constitute at any time an investment of earnings in United
     States property under Section 956 (or any successor provision thereto) of
     the Code that would increase by a material amount the amount of United
     States federal income tax that would otherwise be payable by the Borrower
     and the other members of the affiliated group of corporations filing a
     consolidated federal income tax return with the Borrower in the absence of
     such pledge, as determined by the Borrower based on existing financial
     statements and on financial projections prepared in good faith based upon
     assumptions which the Borrower believes to be reasonable and as evidenced
     by a certificate of the chief financial Authorized Officer of the Borrower
     that is accepted in writing by the Administrative Agent (such acceptance
     not to be unreasonably withheld and which acceptance shall be deemed to
     have occurred in the absence of a written notice from the Administrative
     Agent that is given to the Borrower within five Business Days of the
     Administrative Agent's receipt of such certificate, indicating the reasons

     of the delivery and acceptance of such certificate as provided above,
     require the pledge of such shares of Capital Stock;

          (c)  the Administrative Agent shall have received from each such

                           THE ADMINISTRATIVE AGENT

     SECTION  9.1  Actions.  Each Lender hereby appoints Scotiabank as its
                   -------                                                
Administrative Agent under and for purposes of this Agreement  and each other
Loan Document.  Each Lender authorizes the Administrative Agent to act on behalf
of such Lender under this Agreement, the Notes and each other Loan Document and,
in the absence of other written instructions from the Required Lenders received
from time to time by the Administrative Agent (with respect to which the
Administrative Agent agrees that it will comply, except as otherwise provided in
this Section or as otherwise advised by counsel in order to avoid  contravention
of applicable law), to exercise such powers hereunder and thereunder as are
specifically delegated to or required of the Administrative Agent by the terms
hereof and thereof, together with such powers as may be reasonably incidental
thereto (including the power to release any Lien granted to or held by the
Administrative Agent for the benefit of the Lenders with respect to any
collateral constituting collateral Disposed of in compliance with this Agreement
and the other Loan Documents).  Each Lender hereby indemnifies (which indemnity
shall survive any termination of this Agreement)

the Administrative Agent, pro rata according to such Lender's proportionate
                          --- ----
Total Exposure Amount, from and against any and all liabilities, obligations,
losses, damages, claims, costs or expenses of any kind or nature whatsoever
which may at any time be imposed on, incurred by, or asserted against, the
Administrative Agent in any way relating to or arising out of this Agreement and
any other Loan Document, including reasonable attorneys' fees, and as to which
the Administrative Agent is not reimbursed by the Borrower; provided, however,
                                                            --------  -------
that no Lender shall be liable for the payment of any portion of such
liabilities, obligations, losses, damages, claims, costs or expenses which are
determined by a court of competent jurisdiction in a final proceeding to have
resulted from the Administrative Agent's gross negligence or wilful misconduct.
The Administrative Agent shall not be required to take any action hereunder or
under any other Loan Document, or to prosecute or defend any suit in respect of
this Agreement or any other Loan Document, unless it is indemnified hereunder to
its satisfaction. If any indemnity in favor of the Administrative Agent shall be
or become, in the Administrative Agent's determination, inadequate, the
Administrative Agent may call for additional indemnification from the Lenders
and cease to do the acts indemnified against hereunder until such additional
indemnity is given.

     SECTION  9.2  Funding Reliance, etc.  Unless the Administrative Agent shall
                   ---------------------                                        
have been notified by telephone, confirmed in writing, by any Lender by 3:00
p.m., New York time, on the Business Day prior to a Borrowing that such Lender
will not make available the amount  which would constitute its Percentage of
such Borrowing on the date specified therefor, the Administrative Agent may
assume that such Lender has made such amount available to the Administrative
Agent and, in reliance upon such assumption, make available to the Borrower a
corresponding amount.  If and to the extent that such Lender shall not have made
such amount available to the Administrative Agent, such Lender and the Borrower
severally agree to repay the Administrative Agent forthwith on demand such
corresponding amount together with interest thereon, for each day from the date
the Administrative Agent made such amount available to the Borrower to the date
such amount is repaid to the Administrative Agent, at the interest rate
applicable at the time to Loans comprising such Borrowing (in the case of the
Borrower) and (in the case of a Lender), at the Federal Funds Rate for the first
two Business Days after which such amount has not been repaid and, thereafter,
at the interest rate applicable to Loans comprising such Borrowing.

     SECTION  9.3  Exculpation.  Neither the Administrative Agent nor any of its
                   -----------                                                  
directors, officers, employees or agents shall be liable to any Lender for any
action taken or omitted to be taken by it under this Agreement or any other Loan
Document, or in connection herewith or therewith, except for its own wilful
misconduct or gross negligence, nor responsible for any recitals or warranties
herein or therein, nor for the effectiveness, enforceability, validity or due
execution of this Agreement or any other Loan Document, nor for the creation,
perfection or priority of any Liens purported to be created by any of the Loan
Documents, or the validity, genuineness, enforceability, existence, value or
sufficiency of any collateral security, nor to make any inquiry respecting the
performance by the Borrower or any other Obligor of its obligations hereunder or
under any other Loan Document.  Any such inquiry which may be 

                                     -102-

<PAGE>
 
made by the Administrative Agent shall not obligate it to make any further
inquiry or to take any action. The Administrative Agent shall be entitled to
rely upon advice of counsel concerning legal matters and upon any notice,
consent, certificate, statement or writing which the Administrative Agent
believes to be genuine and to have been presented by a proper Person.

     SECTION  9.4  Successor.  The Administrative Agent may resign as such at
                   ---------                                                 
any time upon at least 30 days' prior notice to the Borrower and all Lenders.
If the Administrative Agent at any time shall resign, the Required Lenders may
appoint another Lender as a successor Administrative Agent which shall thereupon
become the Administrative Agent hereunder.  If no successor Administrative Agent
shall have been so appointed by the Required Lenders, and shall have accepted
such appointment, within 30 days after the retiring Administrative Agent's
giving notice of resignation, then the retiring Administrative Agent may, on
behalf of the Lenders, appoint a successor Administrative Agent, which shall be
one of the Lenders or a commercial banking institution organized under the laws
of the U.S. (or any State thereof) or a U.S. branch or agency of a commercial
banking institution, and having a combined capital and surplus of at least
$250,000,000; provided, however, that if, such retiring Administrative Agent is
              --------  -------                                                
unable to find a commercial banking institution which is willing to accept such
appointment and which meets the qualifications set forth in above, the retiring
Administrative Agent's resignation shall nevertheless thereupon become effective
and the Lenders shall assume and perform all of the duties of the Administrative
Agent hereunder until such time, if any, as the Required Lenders appoint a
successor as provided for above.  Upon the acceptance of any appointment as
Administrative Agent hereunder by a successor Administrative Agent, such
successor Administrative Agent shall be entitled to receive from the retiring
Administrative Agent such documents of transfer and assignment as such successor
Administrative Agent may reasonably request, and shall thereupon succeed to and
become vested with all rights, powers, privileges and duties of the retiring
Administrative Agent, and the retiring Administrative Agent shall be discharged
from its duties and obligations under this Agreement.  After any retiring
Administrative Agent's resignation hereunder as the Administrative Agent, the
provisions of

          (a)  this Article IX shall inure to its benefit as to any actions
                    ----------                                             
     taken or omitted to be taken by it while it was the Administrative Agent
     under this Agreement; and

          (b)  Section 10.3 and Section 10.4 shall continue to inure to its
               ------------     ------------                               
     benefit.

     SECTION  9.5  Loans by Scotiabank.  Scotiabank shall have the same rights
                   -------------------                                        
and powers with respect to (x) the Credit Extensions made by it or any of its
Affiliates, and (y) the Notes held by it or any of its Affiliates as any other
Lender and may exercise the same as if it were not the Administrative Agent.
Scotiabank and its Affiliates may accept deposits from, lend money to, and
generally engage in any kind of business with the Borrower or any Subsidiary or
Affiliate of the Borrower as if Scotiabank were not the Administrative Agent
hereunder.

     SECTION  9.6  Credit Decisions.  Each Lender acknowledges that it has,
                   ----------------                                        
independently of the Administrative Agent and each other Lender, and based on
such Lender's review of the 

                                     -103-

<PAGE>
 
financial information of the Borrower, this Agreement, the other Loan Documents
(the terms and provisions of which being satisfactory to such Lender) and such
other documents, information and investigations as such Lender has deemed
appropriate, made its own credit decision to extend its Commitments. Each Lender
also acknowledges that it will, independently of the Administrative Agent and
each other Lender, and based on such other documents, information and
investigations as it shall deem appropriate at any time, continue to make its
own credit decisions as to exercising or not exercising from time to time any
rights and privileges available to it under this Agreement or any other Loan
Document.

     SECTION  9.7  Copies, etc.  The Administrative Agent shall give prompt
                   -----------                                             
notice to each Lender of each notice or request required or permitted to be
given to the Administrative Agent by the Borrower pursuant to the terms of this
Agreement (unless concurrently delivered to the Lenders by the Borrower).  The
Administrative Agent will distribute to each Lender each document or instrument
received for its account and copies of all other communications received by the
Administrative Agent from the Borrower for distribution to the Lenders by the
Administrative Agent in accordance with the terms of this Agreement or any other
Loan Document.

     SECTION  9.8  Reliance by Administrative Agent.  The Administrative Agent
                   --------------------------------                           
shall be entitled to rely upon any certification, notice or other communication
(including any thereof by telephone, telecopy, telegram or cable) believed by it
to be genuine and correct and to have been signed or sent by or on behalf of the
proper Person, and upon advice and statements of legal counsel, independent
accountants and other experts selected by the Administrative Agent.  As to any
matters not expressly provided for by this Agreement or any other Loan Document,
the Administrative Agent shall in all cases be fully protected in acting, or in
refraining from acting, hereunder or thereunder in accordance with instructions
given by the Required Lenders or all of the Lenders as is required in such
circumstance, and such instructions of such Lenders and any action taken or
failure to act pursuant thereto shall be binding on all of the Lenders.  For
purposes of applying amounts in accordance with this Article, the Administrative
Agent shall be entitled to rely upon any Secured Party that has entered into a
Lender Hedging Agreement with any Obligor for a determination (which such
Secured Party agrees to provide or cause to be provided upon request of the
Administrative Agent) of the outstanding Secured Obligations owed to such
Secured Party under any Lender Hedging Agreement.  Unless it has actual
knowledge evidenced by way of written notice from any such Secured Party and the
Borrower to the contrary, the Administrative Agent, in acting hereunder and each
other Loan Document, shall be entitled to assume that no Lender Hedging
Agreements or Obligations in respect thereof are in existence or outstanding
between any Secured Party and any Obligor.

     SECTION  9.9  Defaults.  The Administrative Agent shall not be deemed to
                   --------                                                  
have knowledge or notice of the occurrence of a Default unless the
Administrative Agent has received notice from a Lender or the Borrower
specifying such Default and stating that such notice is a "Notice of Default".
In the event that the Administrative Agent receives such a notice of the
occurrence of a Default, the Administrative Agent shall give prompt notice
thereof to the 

                                     -104-

<PAGE>
 
Lenders. The Administrative Agent shall (subject to Section 10.1) take such
                                                    ------------
action with respect to such Default as shall be directed by the Required
Lenders; provided that unless and until the Administrative Agent shall have
         --------
received such directions, the Administrative Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such Default as it shall deem advisable in the best interest of the Lenders
except to the extent that this Agreement expressly requires that such action be
taken, or not be taken, only with the consent or upon the authorization of the
Required Lenders or all Lenders.

     SECTION  9.10  Application of Proceeds.   After payment of all amounts then
                    ------------------------                                    
due and payable to the Administrative Agent pursuant to (i) Sections 10.3 and
                                                            -------------    
10.4, (ii) Section 6.3 of the Borrower Security Agreement and the Subsidiary
- ----                                                                        
Security Agreements, (iii) Sections 5.10 and 5.13 of each Mortgage and (iv) each
similar provision under any other Loan Document, all cash proceeds received by
the Administrative Agent in respect of any sale of, collection from, or other
realization upon, all or any part of the Collateral, as defined in the Borrower
Security Agreement, or of the Encumbered Property, as defined in the Mortgage,
shall be applied by the Administrative Agent against, all or any part of the
Obligations as follows:

          (a)  first, to the payment and satisfaction of all costs and expenses
     incurred in connection with the collection of such proceeds;

          (b)  second, to the equal and ratable payment of Obligations, in
     accordance with each Secured Party's Obligations owing to it under or
     pursuant to the Credit Agreement or any other Loan Document (including
     Obligations under or pursuant to any Lender Hedging Agreements of which the
     Administrative Agent has actual knowledge evidenced by written notice
     satisfactory to the Administrative Agent from any such Secured Party or the
     Borrower), applied

               (i)    first to fees and expense reimbursements then due to such
     Secured Party,

               (ii)   then to interest due to such Secured Party,

               (iii)  then to pay or prepay principal of the Loans (and
          Reimbursement Obligations) owing to, or to reduce the "credit
          exposure" of, such Secured Party under such Lender Hedging Agreements,
          as the case may be, and

               (iv)   then to pay the remaining outstanding Obligations and cash
          collateralize all Letter of Credit Outstandings,

          (c)  third, without duplication of any amounts paid pursuant to clause
                                                                          ------
     (b) above, to the Indemnified Parties to the extent of any amounts owing
     ---                                                                     
     pursuant to Section 10.4 of the Credit Agreement; and

                                     -105-

          (d)  fourth, to be held as additional collateral security until the
     payment in full in cash of all of the Obligations, the termination or
     expiration of all Letters of Credit, the termination of all Lender Hedging
     Agreements and the termination of all Commitments, after which such
     remaining cash proceeds shall be paid over to the Borrower or to whomsoever
     may be lawfully entitled to receive such surplus.

     For purposes of this Section, the "credit exposure" at any time of any
Secured Party with respect to a Lender Hedging Agreement to which such Secured
Party is a party shall be determined at such time in accordance with the
customary methods of calculating credit exposure under similar arrangements by
the counterparty to such arrangements, taking into account potential interest
rate movements and the respective termination provisions and notional principal
amount and term of such Lender Hedging Agreement.

     SECTION  9.11  Sub-Agents.  Without limiting any other rights that the
                    ----------                                             
Administrative Agent may have, the Administrative Agent may appoint, upon notice
in writing to the Borrower, any Person to act as a sub-agent with such rights
(including the right to remuneration and indemnity), duties and obligations of
the Administrative Agent as may be conferred or imposed by the Administrative
Agent to or on such sub-agent in the applicable instrument of appointment;
                                                                          
provided that in performing such duties or obligations such sub-agent shall not

be held to any lesser standard of care than that which the Administrative Agent
would have otherwise been held.  The Administrative Agent shall not be
responsible for the acts or omissions of any such sub-agent that it selects with
reasonable care.  The possession of any collateral by any such sub-agent shall
be deemed to be possession by the Administrative Agent.  The Administrative
Agent may agree to pay such sub-agents reasonable fees, together with any
reasonable costs, charges, liabilities and expenses incurred by such sub-agents
in performing their functions as such sub-agents, and such fees, costs, charges,
liabilities and expenses shall for purposes of this Agreement and the other Loan
Documents be treated as costs, charges, liabilities and expenses incurred by the
Administrative Agent.  The Borrower hereby agrees to promptly execute and
deliver all documents related to the appointment of a sub-agent that may be
necessary, or that the Administrative Agent may reasonably request, in order to
effectuate such appointment and allow any such sub-agent to perform its
functions as a sub-agent.

Lender in exercising any power or right under this Agreement or any other Loan
Document shall operate as a waiver thereof, nor shall any single or partial
exercise of any such power or right preclude any other or further exercise
thereof or the exercise of any other power or right.  No notice to or demand on

(y) the assignor Lender, to the extent that rights and obligations hereunder

Agreement, shall be released from its obligations hereunder and under the other
Loan Documents. Within five Business Days after its receipt of notice that the
Administrative Agent has received and accepted an executed Lender Assignment
Agreement (and if requested by the Assignee Lender), but subject to clause (i)
                                                                    ----------

delivery to the relevant Assignee Lender) a new Note evidencing such Assignee
Lender's assigned Loans and Commitments and, if the assignor Lender has retained
Loans and Commitments hereunder (and if requested by such Lender), a replacement
Note in the principal amount of the Loans and Commitments retained by the
assignor Lender hereunder (such Note to be in exchange for, but not in payment
of, the Note then held by such assignor Lender).  Each such Note shall be dated

predecessor Note "exchanged" and deliver each of them to the Borrower.  Accrued
interest on that part of each predecessor Note evidenced by a new Note, and
accrued fees, shall be paid as provided in the applicable Lender Assignment
Agreement.  Accrued interest on that part of each predecessor Note evidenced by
a replacement Note shall be paid to the assignor Lender.  Accrued interest and
accrued fees shall be paid at the same time or times provided in the predecessor
Note and in this Agreement.  Such assignor Lender or such Assignee Lender must
also pay a processing fee in the amount of $3,500 to the Administrative Agent
upon delivery of any Lender Assignment Agreement.  Any attempted assignment and
delegation not made in accordance with this Section shall be null and void.
Notwithstanding anything to the contrary set forth above, any Lender may
(without requesting the consent of the Borrower or the Administrative Agent)
pledge its Loans to a Federal Reserve Bank in support of borrowings made by such
Lender from such Federal Reserve Bank.

In the event that S&P or Moody's, shall, after the date that any Person becomes
a Lender, downgrade the long-term certificate of deposit ratings of such Lender,
and the resulting ratings shall be below BBB- or Baa3, respectively, or the
equivalent, then the Borrower and each Issuer shall each have the right, but not
the obligation, upon notice to such Lender and the Administrative Agent, to
replace such Lender with a financial institution (a "Replacement Lender")
                                                     ------------------

required if the Replacement Lender is an existing Lender), and upon any such
downgrading of any Lender's long-term certificate of deposit rating, each such
Lender hereby agrees to transfer and assign (in accordance with Section 10.11.1)
                                                                ---------------

Agreement and all other Loan Documents (including Reimbursement Obligations) to

without recourse, representation or warranty (other than that such Lender owns
the Commitments, Loans and Notes being assigned, free and clear of any Liens)
and (ii) the purchase price paid by the Replacement Lender shall be in the
amount of such Lender's Loans and its Percentage of outstanding Reimbursement
Obligations, together with all accrued and unpaid interest and fees in respect
thereof, plus all other amounts (other than the amounts (if any) demanded and
unreimbursed under Sections 4.2, 4.3, 4.5 and 4.6, which shall be paid by the

assignment, such Lender shall cease to be a party hereto but shall continue to
be entitled to the benefits of any provisions of this Agreement which by their
terms survive the termination of this Agreement.

     of its Commitments and such other obligations;

          (c)  the Borrower and each other Obligor and the Administrative Agent
     shall continue to deal solely and directly with such Lender in connection
     with such Lender's rights and obligations under this Agreement and each of
     the other Loan Documents;

          (d)  no Participant, unless such Participant is an Affiliate of such
     Lender or is itself a Lender, shall be entitled to require such Lender to
     take or refrain from taking any action hereunder or under any other Loan
     Document, except that such Lender may agree with any Participant that such
     Lender will not, without such Participant's consent, take any actions of
     the type described in clause (a), (b), (f) or, to the extent requiring the

The Borrower acknowledges and agrees that each Participant, for purposes of
                                                                           
Sections 4.3, 4.4, 4.5, 4.6, 4.8, 4.9, 7.1.1, 10.3 and 10.4, shall be considered

sold such participating interest to such Participant concurrently is entitled to
make, and does make, a claim on the Borrower for such increased costs.  Any
Lender that sells a participating interest in any Loan, Commitment or other
interest to a Participant under this Section shall indemnify and hold harmless
the Borrower and the Administrative Agent from and against any taxes, penalties,
interest or other costs or losses (including reasonable attorneys' fees and

result of the failure of the Borrower or the Administrative Agent to comply with
its obligations to deduct or withhold any Taxes from any payments made pursuant
to this Agreement to such Lender or the Administrative Agent, as the case may
be, which Taxes would not have been incurred or payable if such Participant had
been a Non-U.S. Lender that was entitled to deliver to the Borrower, the

     SECTION  10.11.3  Register.  The Borrower hereby designates the 
                       --------                                  
Administrative Agent to serve as the Borrower's agent, solely for the purpose of
this Section, to maintain a register (the "Register") on which the
                                           --------
Administrative Agent will record each Lender's Commitment, the Loans made by
each Lender and the Notes evidencing such Loans, and each repayment in respect
of the principal amount of the Loans of each Lender and annexed to which the
Administrative Agent shall retain a copy of each Lender Assignment Agreement
delivered to the Administrative Agent pursuant to this Section. Failure to make
any recordation, or any error in such recordation, shall not affect the
Borrower's or any other Obligor's Obligations in respect of such Loans or Notes.
The entries in the Register shall be conclusive, in the absence of manifest
error, and the Borrower, the Administrative Agent and the Lenders shall treat
each Person in whose name a Loan and related Note is registered as the owner
thereof for all purposes of this Agreement, notwithstanding notice or any
provision herein to the contrary. A Lender's Commitment and the Loans made
pursuant thereto and the Notes evidencing such Loans may be assigned or
otherwise transferred in whole or in part only by registration of such
assignment or transfer in the Register. Any assignment or transfer of a Lender's
Commitment or the Loans or the Notes evidencing such Loans made pursuant thereto
shall be registered in the Register only upon delivery to the Administrative
Agent of a Lender Assignment Agreement duly executed by the assignor thereof. No
assignment or transfer of a Lender's Commitment or the Loans made pursuant
thereto or the Notes evidencing such Loans shall be effective unless such
