    The Company has no foreign operations. The Company has export sales, 
which accounted for 25% of net sales for the fiscal year ended September 30, 
1997. In the prior two fiscal years, 1996 and 1995, export sales were 28% and 
33%, respectively.

INDUSTRY SEGMENTS

    The following is a general description of the Company's three business 
segments. For additional information concerning developments in these 
business segments during fiscal 1997, reference is made to the Company's 1997 
Annual Report, which is incorporated herein by reference and is included as 
Exhibit 13.
  
                           URANIUM SERVICES & RECYCLE
 
    The Company's Uranium Services and Recycle business segment has the 
technical capabilities and facilities to manufacture depleted uranium metal, 
convert a chemical, uranium hexaflouride (UF6) to uranium tetrafluoride 
(UF4), recycle various low-level radioactive metals, produce DUCRETE-TM- 
shielding, repair depleted uranium and tungsten counterweights for military 
and commercial aircraft, and supply depleted and natural uranium alloy 
material for use in United States Enrichment Company's (USEC) Atomic Vapor 
Laser Isotope Separation (AVLIS) program. The sales and marketing team 
supporting the Uranium Services and Recycle business segment has been 
significantly expanded during 1997 from one local office at Starmet CMI 
located in Barnwell, SC to additional sales offices in Oak Ridge, TN, Idaho 
Fall, ID, Aiken, SC, Washington, DC, and Concord, MA.
 
Recycle of Low-Level Radioactive Metals
 
    The Company demonstrated the technical feasibility and economic soundness of
recycling radioactively contaminated steel into storage drums and boxes for
containment of various radioactive wastes at Department of Energy (DoE) sites.
The DoE facilities have millions of tons of radioactively contaminated carbon
steel and stainless steel in the form of structural components and various types
of processing equipment. Through beneficial reuse of contaminated steel scrap,
the DoE will be able to reduce the volume of low-level radioactive waste in a
cost effective manner. In addition to the DoE facilities, it is estimated that
several million tons of low-level contaminated steel will be generated as a
result of decommissioning the more than 100 currently operating commercial
nuclear power plants over the next 30 years. The Company continues to pursue
additional contracts in this product area using a unique spray casting technique
in partnership with a foreign company.
 
    During fiscal 1997, the Company continued its teaming arrangement with
ALARON Corporation in Cayce, SC offering services to remelt slightly
contaminated steel at the Company's Starmet CMI location. The resultant metal is
used in shielding applications


                                  5

<PAGE>

through an interlocking shield called the RAM-LOC-TM- shielding block.
Radioactively contaminated steel remelt services are offered at only two other
facilities in the United States.

    The Company competes in this market with Scientific Ecology Group and 
British Nuclear Fuels Limited.

Production of DUCRETE-TM-
 
    The Company has licensed the exclusive commercial production rights for a 
DOE patented process known as DUCRETE-TM- shielding. DUCRETE-TM- shielding 
was developed by the Idaho National Engineering Laboratory as a potential 
shielding for spent fuel and high level radioactive waste casks. Starmet 
Corporation has exclusive rights to market this technology in the commercial 
sector. DUCRETE-TM- consists of uranium oxide aggregate combined with 
concrete to form a stable and economical shielding for spent fuel and other 
high level radioactive waste products. The Company is actively pursuing a 
contract with the DoE for conversion of its 55,000 metric tons of Uranium 
Hexaflouride into DU aggregate for DUCRETE shielding production. Spent fuel 
containers produced from DUCRETE-TM- will offer the advantages of portability 
and being 3-5 times more effective than standard concrete. DUCRETE shielding 
has the added advantage of being rail transportable, and, therefore, 
re-useable, unlike conventional concrete, which must be disposed of when 
spent fuel is moved to alternative repositories. Pilot facilities were 
installed during 1997 to convert DU oxides into high density DUCRETE-TM- 
shielding aggregate.

Supply of Depleted Uranium Alloy
 
    The Company supplies DU and Natural Uranium (NU) alloy material to USEC 
for use as AVLIS feed material. AVLIS is expected to replace the current 
gaseous diffusion process for separating the fissionable isotope, U(235), 
from natural uranium within the next ten years. The Company currently is 
performing conversion services for USEC, in converting Depleted Uranium 
Hexaflouride (UF(6)) to Uranium feed materials for the AVLIS prove-out 
program. The Company believes that USEC has a need for conversion of 
approximately 15-20 million pounds annually. The Company continues to be the 
primary supplier of AVLIS feed material. However, other companies are 
expected to compete for future business.

Refurbishment of Counterweights
 
DU is used in production of commercial shielding and counterweight products
requiring the unique properties of DU which include density and ease of
fabrication. Starmet NMI and Starmet CMI are the only FAA approved facilities in
the United States to repair DU aircraft counterweights. The Company refurbishes
DU counterweights for essentially all of commercial and domestic carriers flying
wide body, i.e. DC-10, L-1011, and Boeing 747 aircraft, and has begun work on
military aircraft as well. The Company also has the capability to produce
counterweights. The Company competes primarily for business in North America 
with Cameco of Canada.

Significant Customers
 
    United States Enrichment Corporation (USEC) is a significant customer of the
Uranium Services & Recycle segment. In fiscal 1997, sales to USEC accounted for
14% of net sales. If USEC were lost as a customer, this would have a material
adverse effect on the Company.

                              6

<PAGE>

                            SPECIALTY METAL PRODUCTS
 
    The Company has several specialty metal products, including: beryllium
products; specialty, medical, and aerospace powders; and a variety of advanced
metal products and services for aerospace, energy, and commercial applications.

Beryllium Products--General
 
    Beralcast -Registered Trademark- is the Company's patented investment 
cast beryllium aluminum alloy, an engineering material designed for use in 
electronic and secondary structural applications for a variety of aerospace, 
avionics and commercial applications. Cost and weight pressures on today's 
design engineers demand a transition to lightweight, strong, and high 
stiffness materials such as Beralcast -Registered Trademark-. This alloy 
offers 3 1/2 times the stiffness of aluminum with 22 percent less weight and 
is investment castable to net and near net shapes.
 
    The Company's patents on the alloy compositions for Beralcast -registered 
trademark- materials have approximately 15 years remaining and certain 
process details are trade secrets. Prototypes of a variety of aerospace 
components have been produced and the Company also has produced volume 
quantities of battery cases and navigational components for satellites. Sales 
of Beralcast -Registered Trademark- products at present are made directly to 
manufacturers of assemblies and systems. However, the Company is seeking 
partnering arrangements to enable manufacturing and distribution through 
sites other than its Concord, MA facility. The Company's Beralcast 
-Registered Trademark- sales and marketing organization has been expanded 
greatly during 1997 through establishment of sales offices in Concord, MA, 
Wilmington, MA, Los Angeles, CA, San Jose, CA, Ft. Walton Beach, FL, 
Washington, DC, and Canton, CT, and sales representatives in Europe and Japan.

    The Company competes with Brush Wellman Inc. in the production of beryllium 
products. Beryllium alloys also compete with less expensive materials such as 
stainless steel and other alloys.

                                   7

<PAGE>

Beryllium Products--Defense Applications
 
    High performance defense applications for Beralcast -Registered 
Trademark- include: the Comanche (Advanced Attack Helicopter), the F-22 
(Advanced Tactical Fighter), the PAC-3 (updated Patriot missile), the French 
Rafael (Advanced Fighter Aircraft), and a number of other advanced design 
programs. Lockheed Martin's Apache helicopter work is expected to include 
upgrades to the night vision system. This system, referred to as "B-Kit", is 
part of the advanced system being used on the Comanche program. All 
components are distributed directly to customers who generally are prime 
Government contractors. Beralcast -Registered Trademark- investment castings 
compete directly with aluminum A356 aerospace materials, magnesium, and 
aluminum silicon composites. Other competing materials are titanium and 
stainless steel. Use of Beralcast -Registered Trademark- depends largely on 
the customer's weight, stiffness, and vibration damping needs, in combination 
with a willingness to pay a premium for the materials performance benefits.
 
    Lockheed Martin Corporation will use some 58 Beralcast -Registered 
Trademark- components for its Electro Optic Sensor System (EOSS), the night 
vision system and target acquisition system on the Comanche helicopter, the 
Army's most advanced reconnaissance helicopter. This material has the highest 
priority for provision of Comanche program funding and is in the high growth 
stage of its development as a product.

Beryllium Products--Commercial
 
    Advanced commercial products are brought to the market much faster than 
aerospace and Government products, i.e. 1-2 years instead of 5-10 years. All 
of the Company's current products are sold to OEM's and are distributed 
through its Concord, Massachusetts facility. The Company believes that there 
are additional commercial applications for this unique and patented material 
within the commercial marketplace where a modest cost premium over aluminum 
can yield significant improvements in end product performance. The Company has 
produced prototype quantities of golf club heads and disc drive armatures.
 
    The Company also produces seamless beryllium tubes for satellite
applications. The Company can produce extruded Beralcast -Registered Trademark-
tubing for satellites, intended to supplant expensive graphite composites. The
Company's extrusion technology has been demonstrated successfully in the recent
manufacture of tubing struts for the Comanche EOSS.

Sources of Beryllium
 
    Because the Company is able to use relatively low grade beryllium as 
input metal, the Company has more than one source of beryllium (Be) input 
material. Foreign sources of supply have adequate inventories to support the 
Company's production needs for at least three years. Longer term, the 
Company's strategic objective to become self-sufficient, producing its own 
low cost Be using new conversion technologies.

Advanced Metal Products and Services
 
    Since the early 1960's, the Company has produced bi-metallic transition
joints for joining titanium fuel tanks to stainless steel plumbing in
satellites. These joints are made by a proprietary co-extrusion process
resulting in a bond stronger than the parent metals of the joint. Other
bi-metallic bonding processes compete with our co-extruded products in markets

                                   8

<PAGE>

where bond integrity is not as critical, i.e. cryogenic systems for 
refrigerants. This business segment also produces powder metallurgy bearing 
steel which is used by customers to fabricate fuel linkage bearings in jet 
engines. The Company is a sole source supplier of this product which is in a 
declining market, however, sales of this product are not material to the 
success of the business unit. The Company also provides extrusion services to 
various superconductor and research firms using the Company's 1400 ton, 300 
ton, and 100 ton extrusion presses. Generally, local companies take advantage 
of the Company's extrusion services. All of the foregoing products and 
services are provided directly to a large base of Original Equipment 
Manufacturers (OEM's) and there is no dependency on a single customer. Raw 
materials for these products and services are readily available in the metals 
industry requiring no special processing or long lead times.

Metal Powders
 
    The Company manufactures metal powders by proprietary processes called the
Rotating Electrode Process-TM- (REP) and the Plasma Rotating Electrode
Process-TM- (PREP), which produce spherical metal particles within a relatively
controllable size range. The Company supports its Powders business unit with a
sales office in Concord, Massachusetts, and a representative in Japan.
 
    The metal powders produced by the Company include steel, titanium alloy 
and several nickel and cobalt-base alloys generally known in the industry as 
specialty powders. The Company is in the process of seeking strategic 
alliances to assist the Company in moving ahead with its plans to produce not 
only metal powders, but also components made from the consolidation of these 
powders.
 
    The principal markets for the Company's metal powders are medical
applications (titanium and cobalt-based alloy powders), which use the powder as
a porous coating on medical prostheses, and original equipment manufacturers
(steel, titanium alloy and specialty powders), which fabricate metal parts from
the powder through various processes. In addition, the Company continues to
produce steel powders for the photocopy industry, as a carrier for toner in copy
machines and in high-performance laser printers.
 
    Management believes that the metal powders produced by its manufacturing 
processes offer significant advantages for certain product applications 
compared with metal powders produced by other processes. In particular, the 
processes result in inherently "cleaner" powders, more uniformly spherical 
particles and a higher percentage of particles within the desired size range 
from a given amount of raw material.
 
    Key competitive factors in the metal powders market are price and the 
ability to meet exact dimensional, metallurgical and other specifications. 
The steel powder marketed by the Company for photocopy applications competes 
with less expensive powders produced by larger manufacturers. The Company 
believes that the quality of its powder used in the photocopy processes helps 
to offset any price advantage that may exist for competing powders in this 
price sensitive market.

Sources of Raw Materials
 
    The principal raw material for the Company's steel powder is cold-rolled
steel bars, which are readily available. Other metal powders are manufactured to
customer specifications,

                                         9

<PAGE>

and the metals for these powders are generally available for purchase in job
lots from specialty metal suppliers.

Patents
 
    The Company holds three U.S. patents relating to developments in Rotating
Electrode Process production equipment, which provide patent rights through the
year 2001. These patents also are filed and effective in the principal
industrialized European countries, Canada, Israel and Japan. Management believes
that, although the original patent on the Rotating Electrode Process machine
expired in July 1980, the development patents continue to benefit the Company's
competitive position in the Metal Powders market. It is also the opinion of
management that the technical expertise which has evolved from the development
and manufacture of metal powders is of equal importance in maintaining the
Company's competitive position.

Significant Customers
 
    Lockheed Martin Corporation (LMC) is a significant customer of the Company's
Specialty Metal Products segment. In fiscal 1997, sales to LMC accounted for 7%
of sales (See Note 1 of Notes to Consolidated Financial Statements). The Company
currently is under several contracts with LMC to provide
Beralcast-Registered Trademark- hardware for the Comanche Helicopter Program.
The loss of LMC as a customer would have a material adverse effect on the
Company.
 
    Lockheed Idaho Technology Company (LITCO) is another significant customer of
the Company's Specialty Metal Products segment. In fiscal 1997, sales to LITCO
accounted for 5% of net sales. The Company currently is under contract with
Lockheed Idaho Technology Company to produce, from furnished DU recycle metal,
DU castings for the U.S. Army's heavy armor tank program. This contract
continues to have options for several additional years. The loss of LITCO as a
customer would have a material adverse effect on the Company.
 
                          DEPLETED URANIUM PENETRATORS
 
    The Company believes it is a technological leader in the manufacture of
depleted uranium penetrators. Depleted uranium (DU) is a dense, heavy metal that
is 68% heavier than lead. Because of its density and workability, DU is an
effective low-cost material for anti-armor ammunition and is used in numerous
United States Government and foreign government weapons systems. DU is a
low-level radioactive material which is a by-product of the production of
enriched uranium for nuclear fuel and weapons.
 
    The Company competes with Aerojet Ordnance, a division of GenCorp Inc., 
as one of two domestic DU penetrator manufacturers. The principal DU products 
manufactured by the Company, referred to as penetrators, have application in 
various military gun systems. The Company generally sells penetrators 
directly to prime ammunition contractors. The U.S. Government has funded and 
owns a portion of the manufacturing machinery and equipment used by the 
Company for producing penetrators.

                                 10
<PAGE>

    Company continues to produce M829A2 penetrators under a production 
contract with options extending production to the year 1999. This contract is 
subject to appropriations by the Government. The Company currently is in 
production on the third option of this contract. Management strongly believes 
the Government will exercise the remaining option on the contract. The 
Company will continue to pursue both domestic and foreign military depleted 
uranium penetrator production requirements, however, the market for DU 
ordnance is declining, and near term orders are not expected.
 
    During December 1998, the Company will complete an order for DU products 
from a UK customer to support its UK based manufacture of tank ammunition 
containing DU penetrators. This material will complete the customer's near 
term requirements for this type of ammunition and follow-on orders are not 
anticipated within the next 5 years. None of the business practices used in 
this business segment are considered proprietary.
 
    The Company plans to move its DU operations to its Barnwell, South 
Carolina facility as DU products reach the point where the volume of such 
operations are no longer practical at the Concord, MA facility.
 
Significant Customers
 
    Royal Ordnance, a U.K. defense contractor, is a significant customer of 
the Company's Depleted Uranium Penetrator segment. In fiscal 1997, sales to 
Royal Ordnance accounted for 19% of net sales. The Company currently is under 
contract to manufacture penetrator blanks for Royal Ordnance with a 
completion date of December, 1998.
 
    Primex Technologies is also a significant customer of the Company's 
Depleted Uranium Penetrator segment. In fiscal 1997, sales to Primex 
Technologies accounted for 12% of net sales. The Company currently is under 
contract to provide Primex Technologies with 120mm penetrators for the U.S. 
Army's ABRAMS Tank program with options extending another three years.
 
    If Royal Ordnance and Primex Technologies were lost as customers in the 
short term, this would have a material adverse effect on the Company. Both 
customers have finite contracts with the conracts with the Company and 
additional contract requirements from these customers are considered 
unlikely. Management believes that expansion of its Beralcast-Registered 
Trademark-product lines as well as growth in its uranium services and recycle 
industry segment over the next few years will minimize the effect on the 
Company of these probable reductions in contract requirements from these 
customers.

Marketing
 
    The Company relies on a variety of marketing strategies, including 
advertising and direct sales. Technical papers given at industry symposia, 
presented both by Starmet and in conjunction with customers, also are used as 
marketing vehicles for the Company's advanced metal products and services. 
Strategic alliances are being developed with several key customers

                                     12

<PAGE>

to strengthen the Company's customer and product base into the future and to 
reduce costs through joint research and development costs and marketing 
efforts.
 
    Understanding the importance of Design-To-Cost principles, especially 
those of Lockheed Martin Corporation, is essential to strategic teaming with 
our Beralcast-Registered Trademark- customers. Concentrated efforts on cost 
reduction in the form of Concurrent Engineering, low cost Beryllium metal 
production, facility expansion, and other efforts, add value for future sales 
volumes. Starmet has introduced Nucast, our Beralcast-Registered 
Trademark-teammate, to these cost reduction ideas which is expected to form 
the basis for improved cost competitiveness in the future. Direct marketing 
efforts are increasing.
 
    The Company is committed to expanding its product and customer base for 
metal powders. Market demands for fine metal powders, for re-consolidation or 
incorporation into metal matrix composites, are on the rise and the Company is
positioning itself to exploit these opportunities. Novel product requirements 
for our advanced metal products and services will continue to receive the 
utmost attention for expansion of the Company's product base. A significant 
portion of the Company's business is dependent on the award of contracts or 
subcontracts for the supply of products and materials to governmental 
departments and agencies. Payment to the Company of all or a portion of the 
amounts called for under such contracts or subcontracts, is often subject to 
legislative funding appropriations, government agency purchasing requirements 
and other conditions and factors beyond the Company's control. Accordingly, 
the Company's performance under such contracts may be delayed or may not 
commence at all, in which case the payments thereunder may be recognized 
later than anticipated at the time of the contract award or not at all in 
cases in which the Company is not called upon to perform. As a result, the 
timing and amount of revenues under such government contracts is uncertain 
and subject to change, which may result in fluctuations in the Company's 
operating results and cash flows.

RESEARCH AND DEVELOPMENT ACTIVITIES
 
    The Company engages in research activities to develop new products or 
enhance existing products for new applications. Research and development is 
funded both by the Company and through customer sponsored programs. During 
the past fiscal year, funded research and development has been sponsored by 
the Department of Defense, Department of Energy, and various commercial 
customers.
 
    The Company's is involved in research covering a variety of product areas 
for applications of Beralcast-Registered Trademark- (beryllium aluminum) 
castings, Dmetal powders, and uranium processing technology. The highlights of 
R&D activities in the Uranium Services & Recycle Product segment include 
recycling processes for radioactively contaminated steel scrap, uranium 
production technology for AVLIS feedstock, removal of uranium from MgF(2) slag, 
conversion of UF to uranium oxide, and the manufacture of DUCRETE-TM- as a 
means of incorporating depleted uranium oxide aggregate in a cement matrix to 
make shielded concrete structures. The Company built a pilot plant to 
manufacture uranium oxide aggregate for DUCRETE-TM- and is developing the 
process knowledge required to support large scale production. R&D activities 
in the Specialty Metal Products segment included development of new casting 
processes and alternative methods and forming and manufacturing of 
Beralcast-Registered Trademark- alloys. The Company expects that this 
research will lead to products suitable for commercial mass 
production markets and extend the application of Beralcast-Registered 
Trademark- products in the aerospace and military markets. The Company has 
developed a method for producing fine titanium metal powders

                                    13

<PAGE>

as an extension of our PREP-Registered Trademark- method for making for 
making spherical powders form reactive metals such as titanium, and the 
Company is exploring new methods for utilizing titanium powder in the 
manufacture of metal parts.
 
    The Company also participates in certain cooperative research and 
development activities through arrangements with selected customers and 
Government agencies where there is potential for utilizing proprietary 
technology or specialized resources not directly available to the Company. 
The Company employs a staff of six Ph.D. technologists with backgrounds in 
chemistry, mechanical and metallurgical engineering to conduct research and 
new product development. In addition, the Company has on the R&D staff a 
former Government scientist who invented the DUCRETETM technology. The cost 
for Company-sponsored research and development activities was $1,309,000 in 
fiscal 1997, $876,000 in fiscal 1996, and $439,000 in fiscal 1995. Total 
revenues from customer-funded research and development were $793,000 in 
fiscal 1997, $1,812,000 in fiscal 1996 and $557,000 in fiscal 1995. These 
revenues are included in the revenues of the industry segment to which the 
research and development relates.
 
ENVIRONMENTAL, SAFETY AND REGULATORY MATTERS
 
In General
 
    Two of the materials regularly processed by the Company, depleted uranium 
and beryllium, have characteristics considered to be health or safety hazards 
by various federal, state or local regulatory agencies. Processing of these 
materials requires a high level of safety consciousness, personnel monitoring 
devices and special equipment. Depleted uranium is a low-level radioactive 
material, and the Company is subject to regulation by the United States 
Nuclear Regulatory Commission (NRC). Depleted uranium in the finely divided 
state, such as grinding dust or machine turnings, is combustible at room 
temperature and requires special handling for safe operations and disposal of 
process wastes. Beryllium is known to cause lung disease following 
significant exposure by inhalation of airborne particles. Processing this 
material requires use of extensive ventilation and dust collecting systems. 
Management believes that the experience gained in its many years of working 
with these metals has resulted in capabilities for dealing effectively with 
their special characteristics.
 
    The presence and use in the Company's operations of materials with 
hazardous characteristics subjects the Company to regulation and scrutiny by 
various governmental agencies. Management believes that the Company is 
presently in compliance in all material respects with existing federal, state 
and local regulations and has no knowledge of any threatened actions against 
the Company for violations of any such laws, statutes or regulations, except 
as described below under "Concord Site Remediation and Decommissioning 
Planning Requirements" and in Item 3 below. However, the potential effects of 
evolving legislation and regulations affecting the Company's business cannot 
be predicted.
 
    In the process of manufacturing depleted uranium products, the Company 
generates low-level radioactive waste materials that must be disposed of at 
sites licensed by federal, state, and local governments. With the closing of 
the Barnwell, South Carolina, low-level radioactive waste repository to 
out-of-region generators in July 1994, the Company began storing waste on 
site in Concord and Barnwell. Interim storage is permitted under the 
Company's licenses. At present, the Barnwell repository remains available for 
use by the Company's Starmet CMI facility. The Company has made provisions to 
accommodate an extended period of interim

                                    14

<PAGE>

storage of waste within existing buildings in Concord as the state government 
works toward a regional solution. At the same time, the Company has made 
significant progress in developing and instituting alternatives to disposal 
of its waste. The Company intends to continue the development of technologies 
and processes aimed at eliminating the generation of waste materials 
associated with its manufacturing process.

    For a number of years, ending in 1985, the Company deposited spent acid 
and associated depleted uranium waste and other residual materials by 
neutralizing with lime and discharging the neutralized mixture to a holding 
basin on its premises in Concord, Massachusetts. In 1986, the holding basin 
was covered with Hypalon, an impervious material used to prevent rain and 
surface run-off water from leaching through the holding basin. The Company 
now uses a proprietary "closed loop" process that it developed to discontinue 
such discharges. The Company believes that both practices were and are in 
compliance with all applicable regulations. The Company now is in the process 
of removing and disposing of the material in the holding basin. For a 
discussion of the status of remediation of the holding basin at the Company's 
Concord facility, see "Concord Site Remediation and Decommissioning Planning 
Requirements" elsewhere herein.
 
Concord Site Remediation and Decommissioning Planning Requirements
 
    The Company is required to maintain certain licenses issued by the 
Massachusetts Department of Public Health ("DPH") and the South Carolina 
Department of Health and Environmental Control ("DHEC") in order to possess 
and process depleted uranium materials at its facilities in Massachusetts and 
South Carolina, respectively. Under applicable licensing regulations 
pertaining to decommissioning and disposal of certain hazardous materials 
("D&D") at licensed sites, the Company submitted to the Nuclear Regulatory 
Commission ("NRC") and the applicable state agencies a Decommissioning 
Funding Plan ("DFP") to provide for possible future decommissioning of its 
facilities. The Concord Facility DFP estimated cost is $11.7 million and the 
Barnwell Facility DFP estimate is $2.9 million. The Company is required to 
provide financial assurance for such decommissioning pursuant to applicable 
regulations. The Company has satisfied these requirements and as a result, 
the site licenses for both locations have been renewed.
 
    Substantially all of the depleted uranium materials to which the DFP 
requirements apply were processed by the Company for the United States 
Government. Based on the terms of certain contracts that the Company entered 
into with the United States Government to process such depleted uranium 
materials, the Company believes that such materials continue to be owned by 
the United States Government and that the United States Government is 
obligated, under applicable law, to pay for its percentage of eventual D&D. 
The Company's DFP's reflect its position that it is obligated to provide 
financial assurance only with respect to the portion of the materials which 
are attributable to the Company's commercial production for parties other 
than the United States Government, and that this obligation, has been 
satisfied by a letter of credit to each geographic locations regulatory 
agency.

    The United States Army, in a memorandum of Decision dated September 13, 
1996, determined pursuant to Public Law 85-804, that it should fund 
remediation of the Concord holding basin site as well as D&D related to the 
Concord facility, based in part on the Army's determination that the 
Company's activities are essential to the national defense. The United States 
Army has issued to the Company a fixed price subcontract for remediation of 
the holding basin and the Company entered into a fixed price subcontract with 
a contractor to perform this remediation. This work is expected to continue 
into the first half of fiscal 1998. The Company's contract with the 
contractor is fixed price based on a specified volume of waste to be removed 
from the basin and delivered to a burial site. If the volume of the material 
removed exceeds the specified level then the Company is obligated to pay an 
additional fee per cubic yard of excess material removed. Based on the 
current estimates, management believes that the amount of material to be 
removed will not exceed the specified amount and that the fixed price 
contract issued by the United States Army will be adequate to fully fund the 
remediation of the basin. The Army has provided written assurances (subject 
to funding appropriations) of its intention to provide funding for D&D costs 
at the Concord facility under future contracts or, in the event that no 
future contracts were awarded (which the Army has indicated is unlikely in 
view of its current

                                     15

<PAGE>

plans), under an existing contract. D&D costs for the Company's CMI facility 
are covered by the existing letter of credit. The Company has no written 
assurance that the Army will accept responsibility for the share of the 
estimated cost of D&D at its South Carolina facility which directly resulted 
from production work under U.S. government contracts on government supplied 
materials. However, based on the advice of legal counsel, management believes 
that the Army is responsible for its estimated share of D&D.

ITEM 3. LEGAL PROCEEDINGS
 
    The Company is named as a Potentially Responsible Party (PRP) in regard 
to the Maxey Flats, Kentucky, Superfund Site. This site was used until 1977 
as a licensed and approved low level radioactive waste disposal site. A 
committee of PRP's, including the Company, has submitted a remedial 
investigation and feasibility study report to the Environmental Protection 
Agency. The agreement signed by the settling parties in July 1995, outlines 
the responsibilities of all parties and states that the PRP's will undertake 
the initial remedial phase (IRP) of the site remediation at an estimated cost 
of $60 million. The Company's liability is not expected to exceed 
approximately $80,000 over 10 years. For a discussion of proceedings related 
to the recent renewal of the Company's nuclear regulatory licenses, see Part 
I, Item 1 "Business - Environmental, Safety and Regulatory Matters--Concord 
Site Remediation and Decommissioning Planning Requirements"' elsewhere herein.
 
    On December 9, 1997, Brush Wellman, Inc. ("Brush Wellman") filed a patent 
infringement suit against Starmet Corporation in United States District Court 
for the District of Massachusetts (Case No. 97-12705-RCO) alleging that the 
Company is infringing a patent awarded to Brush Wellman for the investment 
casting of aluminum beryllium alloys. Brush Wellman currently holds U.S. 
Patent No. 5,642,773 entitled "Aluminum Alloys Containing Beryllium and 
Investment Casting of Such Alloys." Brush Wellman is seeking an injunction of 
the Company's alleged patent infringement, monetary damages (including treble 
damages) and attorney fees. The Company has been advised by patent counsel 
that Brush Wellman's claims are without merit and that Brush Wellman's patent 
is invalid. The Company's answer to Brush Wellman's complaint is due December 
30, 1997, unless the date for filing an answer is extended, and the Company 
intends to challenge the validity of Brush Wellman's patent, deny any patent 
infringement by the Company and assert counterclaims against Brush Wellman.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
    To the Board of Directors and Stockholders of Starmet Corporation:
 
    We have audited the accompanying consolidated balance sheets of Starmet 
Corporation (formerly Nuclear Metals, Inc.) (a Massachusetts Corporation) and 
subsidiaries as of September 30, 1997 and 1996, and the related consolidated 
statements of operations, stockholders' equity and cash flows for each of the 
three years in the period ended September 30, 1997. These financial 
statements are the responsibility of the Company's management. Our 
responsibility is to express an opinion on these financial statements based 
on our audits.
 
    We conducted our audits in accordance with generally accepted auditing 
standards. Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements are free 
of material misstatement. An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements. 
An audit also includes assessing the accounting principles used and 
significant estimates made by management, as well as evaluating the overall 
financial statement presentation. We believe that our audits provide a 
reasonable basis for our opinion.
 
    In our opinion, the consolidated financial statements referred to above 
present fairly, in all material respects, the financial position of 
Starmet Corporation and subsidiaries as of September 30, 1997 and 1996, and the 
results of their operations and their cash flows for each of the three years 
in the period ended September 30, 1997, in conformity with generally accepted 
accounting principles.
 
    Our audit was made for the purpose of forming an opinion on the basic 
financial statements taken as a whole. The schedule listed in the index of 
the financial statements is presented for purposes of complying with the 
Securities and Exchange Commission rules and is not part of the basic 
financial statements. This schedule has been subjected to the auditing 
procedures applied in the audit of the basic financial statements and, in our 
opinion, fairly states in all material respects the financial data required 
to be set forth therein in relation to the basic financial statements taken as 
a whole.
