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

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.

                     PROVISIONS AS TO INTERCOMPANY DEALINGS

         The Corporation may enter into contracts or transact business with one
or more of its directors, officers, or stockholders or with any corporation,
organization or other concern in which one or more of its directors, officers or
stockholders are directors, officers, shareholders, or otherwise interested and
other contracts or transactions in which any one or more of its directors,
officers or stockholders is in any way interested; and, in the absence of fraud,
no such contract or transaction shall be invalidated or in any wise affected by
the fact that such directors, officers, or stockholders of the Corporation have
or may have interests which are or might be adverse to the interest of the
Corporation even though the vote or action of directors, officers or
stockholders having such adverse interests may have been necessary to obligate
the Corporation upon such contract or transaction.  At any meeting of the Board
of Directors of the Corporation (or any duly authorized committee thereof) any
such director or directors may vote or act thereat with like force and effect as
if he had no such interest, provided, in such case the nature of such interest
(though not necessarily the extent or details thereof), shall be disclosed or
shall have been known to the directors or a majority thereof.  A general notice
that a director or officer is interested in any corporation or other concern of
any kind referred to shall be sufficient disclosure as to such director or
officer with respect to all contracts and transactions with such corporation or
other concern.  No director shall be disqualified from holding office as
directors or officers of the Corporation by reason of any such adverse interest,
unless the interest is detrimental to the Corporation.  In the absence of fraud,
no director, officer or stockholder having such adverse interest shall be liable
to the Corporation or to any stockholder or creditor thereof or to any other
person for any loss incurred by it under or by reason of such contract or
transaction, nor shall any such director, officer or stockholder be accountable
for any gains or profits realized thereon.


                      INDEMNIFICATION OF DIRECTORS AND OFFICERS

         The corporation may indemnify and hold harmless each director and each
officer or other employee of the Corporation against and from all loss, cost and
reasonable expenses hereafter incurred by him in the payment, settlement and
defense of any civil or criminal claim, action or proceeding (including appeals)
brought or threatened against him because he is or has been such director or
officer or other employee or because of any action alleged to have been taken or
omitted by him as such director or officer 


<PAGE>


or other employee.  The rights of indemnification and exoneration accruing under
this Article shall apply whether or not such person continues to be a director
or officer or other employee at the time any such loss, cost or expense is
suffered or incurred.

         The corporation may advance expenses to, or where appropriate may
itself at its expense undertake the defense of, such director or officer or
other employee; provided, however, that he shall have undertaken to repay or to
reimburse such expenses if it should ultimately be determined that he is not
entitled to indemnification under this provision.

         Such indemnification shall be of right if (1) such director or officer
or other employee shall have been wholly successful, on the merits or otherwise,
with respect to such claim, action or proceeding, or (2) the stockholders of
this Corporation at the time the subject is first presented to them for
determination, by vote of the holders of a majority of the shares entitled to
vote (excluding from shares entitled to vote all those held by each person whose
conduct is under consideration) determined that such director or officer or
other employee acted in good faith for a purpose which be reasonably believed to
be in the best interest of the Corporation and had no reasonable cause to
believe that his conduct was unlawful.  Subject to the next following paragraph,
no disposition of any such claim, action or proceeding shall preclude such
determination by the shareholders.     

         Such rights shall not apply in relation to any matters:  (1) as to
which such director or officer or other employee shall be adjudged in final
judgment in such action or proceeding to be liable for wilful misconduct or for
his own negligence; or (2) as to which, if there is not final judgment, the
stockholders of this Corporation at the time the subject is first presented to
them for determination, by vote of the holders of a majority of the shares
entitled to vote (excluding from shares entitled to vote all those held by each
person whose conduct is under consideration) determine that such director,
officer, or other employee has suffered or incurred such loss, cost, or expense
as the result of his wilful misconduct or negligence; or (3) in the case of
matters involving the allegation of crime, as to which such director or officer
or other employee shall have been adjudged in such claim, suit or proceeding to
have had reasonable cause to believe that his conduct was unlawful; or (4)
brought or asserted by or in behalf of the Corporation.

         The rights provided for herein shall not be deemed exclusive of any
other rights to which any such person may be otherwise entitled, nor shall this
provision restrict the right of the Corporation to indemnify or reimburse any
such person in any proper case even though not specially provided for herein. 
The rights provided for herein shall apply to persons who act or have acted at
the request of the Corporation as directors or officers of other corporation in
which this Corporation is or has been interested as an 


<PAGE>


investor or a creditor.  A person may be entitled to indemnification as to some 
matters even though he is not so entitled as to others.


                             AMENDMENT OF BY-LAWS

         The Board of Directors may amend the By-Laws, except with respect to
any provision thereof which by law, the Articles of Organization or the By-Laws
requires action by the stockholders.  Not later than the time of giving notice
of the meeting of stockholders next following the amending, notice thereof
stating the substance of such change shall be given to all stockholders.

                             STOCKHOLDERS' MEETINGS

         The meetings of stockholders may be held anywhere within the United
States.

                            COMMON STOCK PURCHASE WARRANT


    THIS CERTIFIES that, in consideration of value received, Roger Marino 
(the "Holder"), is entitled, upon the terms and subject to the conditions 
hereinafter set forth, to subscribe for and purchase from Nuclear Metals, 
Inc., a Massachusetts corporation (the "Company"), Sixty Thousand (60,000) 
fully paid and nonassessable shares of the Company's Common Stock, $0.10 par 
value per share (the "Common Stock").  The number and exercise price of the 
securities that may be purchased upon the exercise of this Common Stock 
Purchase Warrant (the "Warrant") are subject to adjustment as provided herein.

    1.   Exercise Period and Price - The purchase rights represented by this 
Warrant are exercisable by the Holder, in whole or in part, at any time from 
time to time during the Exercise Period at the Exercise Price.  The Exercise 
Price shall initially be $17.875 per share of Common Stock subject to 
adjustment as hereinafter provided.  

    The Exercise Period shall commence at 9:00 a.m. Boston, Massachusetts 
time on the date first set forth above and shall end at 5:00 p.m. Boston, 
Massachusetts time on the third anniversary of such date.  

    2.   Exercise of Warrant - During the Exercise Period and provided this 
Warrant has not been terminated, this Warrant shall be exercised, in whole or 
in part and from time to time, by the surrender of this Warrant and the 
Notice of Exercise annexed hereto duly executed at the principal office of 
the Company, in Boston, Massachusetts (or such other office or agency of the 
Company as it may designate) and upon payment of the Exercise Price of the 
shares thereby purchased (payment to be by check or bank draft payable to the 
order of the Company).  If the amount of the payment received by the Company 
is less than

<PAGE>


the Exercise Price, the Holder will be notified of the deficiency and shall 
make payment in that amount within three days.  In the event the payment 
exceeds the Exercise Price, the Company will refund the excess to the holder 
within three days of receipt.  Upon exercise, the Holder shall be entitled to 
receive, within a reasonable time after payment in full, one or more 
certificates, issued in the Holder's name or in such name or names as the 
Holder may direct, subject to the limitations on transfer contained herein, 
for the number of shares of Common Stock so purchased.  The shares so 
purchased shall be deemed to be issued as of the close of business on the 
date on which this Warrant shall have been exercised.

    The Company covenants that all shares of Common Stock that are issued 
upon the exercise of rights represented by this Warrant will be fully paid, 
nonassessable, and free from all taxes, liens and charges in respect of the 
issue thereof (other than taxes in respect of any transfer occurring 
contemporaneously with such issue).

    3.   No Fractional Shares or Scrip - No fractional shares or scrip 
representing fractional shares shall be issued upon the exercise of this 
Warrant.  In lieu thereof, a cash payment shall be made equal to such 
fraction multiplied by the Exercise Price per share as then in effect.

    4.   Charges, Taxes and Expenses - Issuance of certificates for shares of 
Common Stock upon the exercise of this Warrant shall be made without charge 
to the Holder for any issue or transfer tax or other incidental expense in 
respect of the issuance of such certificate, all of which taxes and expenses 
shall be paid by the Company.

    5.   No Rights as Shareholder - This Warrant does not entitle the Holder 
to any voting rights or other rights as a shareholder of the Company prior to 
exercise and payment of the Exercise Price in accordance with Section 2 
hereof.  

    6.   Sale or Transfer of the Warrant; Legend - This Warrant shall not be 
sold or transferred unless either (i) it first shall have registered under 
the 1933 Act and any applicable state securities laws, or (ii) the Company 
first shall have been furnished with an opinion of legal counsel reasonably 
satisfactory to the Company to the effect that such sale or transfer is 
exempt from the registration requirements of the 1933 Act and such state 
laws.  Each certificate representing any Warrant that has not been registered 
and that has not been sold pursuant to an exemption that permits removal of 
the legend shall bear a legend substantially in the form of the legend 
affixed to this Warrant.

Upon the request of a holder of a certificate representing any Warrant, the 
Company shall remove the foregoing legend from the certificate or issue to 
such holder a new certificate therefor free of any transfer legend, if, with 
such request, the Company shall have received either (i) an opinion of 
counsel reasonably satisfactory to the Company to the effect that such legend 
may be removed from such certificate or (ii) if the present Paragraph (k) of 
Rule 144 or a substantially similar successor rule remains in force and 
effect, representations from the 

                                         -2-
<PAGE>


holder that such holder is not then, and has not been during the preceding 
three months, an affiliate of the Company and that such holder has 
beneficially owned the security (within the meaning of Rule 144) for three 
years or more.

    Such Warrant may be subject to additional restrictions on transfer 
imposed under applicable state and federal securities law.

    7.   Adjustments

         7.1  Adjustments for Stock Splits, Reverse Stock Splits and Stock 
Dividends     In the event that the outstanding shares of Common Stock shall 
be subdivided (split), combined (reverse split), by reclassification or 
otherwise, or in the event of any dividend payable on the Common Stock in 
shares of Common Stock, the number of shares of Common Stock available for 
purchase in effect immediately prior to such subdivision, combination, or 
dividend shall be proportionately adjusted. 

         7.2  Adjustment for Capital Reorganizations - If at any time there 
shall be a capital reorganization of the Company or a merger or consolidation 
of the Company with or into another corporation, or the sale of the Company's 
properties and assets as, or substantially as, an entirety to any other 
person, then, as part of such reorganization, merger, consolidation, or sale, 
lawful provision shall be made so that the Holder of this Warrant shall 
thereafter be entitled to receive on exercise of this Warrant during the 
period specified in this Warrant and on payment of the Exercise Price then in 
effect, the number of shares of stock or other securities or property of the 
Company, or of the successor corporation resulting from such merger or 
consolidation, to which a holder of the Common Stock deliverable on exercise 
of this Warrant would have been entitled on such capital reorganization, 
merger, consolidation, or sale if this Warrant had been exercised immediately 
before that capital reorganization, merger, consolidation, or sale.  In any 
such case, appropriate adjustment, as determined in good faith by the Board 
of Directors of the Company, shall be made in the application of the 
provisions of this Warrant with respect to the rights and interests of the 
Holder of this Warrant after the reorganization, merger, consolidation, or 
sale to the end that the provisions of this Warrant (including adjustment of 
the number of shares purchasable on exercise of this Warrant) shall be 
applicable after that event, as near as reasonably may be, in relation to any 
shares or other securities or property deliverable after that event on 
exercise of this Warrant.

         7.3  Certificate as to Adjustments - Upon the occurrence of each 
adjustment or readjustment pursuant to this Section 7, the Company at its 
expense shall promptly compute such adjustment or readjustment in accordance 
with the terms hereof and furnish to each Holder a certificate setting forth 
such adjustment or readjustment and showing in detail the facts upon which 
such adjustment or readjustment is based.  The Company shall, upon the 
written request, at any time, of any Holder, furnish or cause to be furnished 
to such Holder, a like certificate setting forth:  (i) such adjustments and 
readjustments; (ii) the Exercise Price at the time in effect; and (iii) the 
number of shares of Common Stock and the 

                                         -3-
<PAGE>

                                 EMPLOYMENT AGREEMENT

    This Agreement is made effective as of the first day of October, 1997, by

    WHEREAS, the Corporation is engaged in the business of developing and 
marketing metallurgical and other products; and

    WHEREAS, the Employee is employed by the Corporation as its Vice 
President, Finance; and

    WHEREAS, the parties hereto wish to describe the terms under which the

    NOW, THEREFORE, in consideration of the foregoing promises and the mutual 
agreements herein contained, the parties hereto agree as follows:

Corporation during the Term of this Agreement and according to the terms and 
conditions hereof.

limiting the generality of the foregoing, such activities shall include

    3.   COMPENSATION

         3.1  INITIAL COMPENSATION

         The Employee's compensation shall be at the mimimum annual rate of
    $142,000 for the Term of this Agreement.

         3.2  PAYMENTS

         Such compensation shall be paid to the Employee on a weekly, bi-weekly
    or monthly basis, consistent with the Corporation's normal practice in
    paying compensation to its other executive employees.

         3.3  INCREASES

         The Board of Directors or President may, from time to time during the
    Term of this Agreement, review compensation and such compensation may be
    increased (but not decreased below the levels provided in this Agreement)

    and of the Corporation and the salary levels prevailing generally for
    positions of comparable responsibility.

         3.4  BONUSES

         In addition to the foregoing initial compensation, the Corporation may
    pay the Employee a bonus in any year in such amount as may be determined by

<PAGE>

         4.1  BENEFIT PLANS

         The Corporation shall include the Employee in all of its benefit
    plans, including stock option plans, vacation, pension benefits and major
    medical, accident and health insurance, while he remains an active employee

         4.2  NO REDUCTION OF BENEFITS

         The Corporation shall not eliminate or reduce benefits in effect on
    the date hereof.

    5.   TERMINATION

         5.1  TERMINATION PAYMENTS

         The Board of Directors of the Corporation acting on behalf of the
    Corporation and after notice and an opportunity to be heard, may terminate
    the Employee's employment hereunder if a majority of the whole number of
    Directors then in office determines, in good faith, that:

         (a)       the Employee has willfully refused to perform substantially
    all of the services required of him hereunder; or

         (b)   the Employee has been convicted of a crime of moral turpitude.

    In such event, or in the event of voluntary termination by the Employee
    without "good reason," as herein defined, the Employee's right to all
    future payments set forth in Article 3 hereof shall cease; or

         (c)   prior to a "change of control," as herein defined, by either
    party on twelve months' written notice to the other.  "Change of control"
    shall mean (i) a change (other 

                                         -3-
<PAGE>


    than a change resulting from death, retirement or disability) in the
    identity of a majority of the Board of Directors of the Corporation or in
    the identity of both the President and Chairman of the Board of the
    Corporation, or (ii) the occurrance of a transaction or event which a
    majority of directors of the Corporation in office immediately prior to
    such transaction deem to involve a change of control.

         5.2  DEATH

         In the event of the death of the Employee, payments set forth in
    subsection 3.1 shall be made to the executor or administrator or other
    personal representative of the decedent and shall be continued until the
    earlier of one year from the date of death of the Employee or the end of
    the Term of this Agreement.

         5.3  OTHER TERMINATIONS

         In the event of termination by the Corporation other than pursuant to
    subsection 5.1 or of termination by the Employee for good reason, the
    amounts payable pursuant to said subsection 3.1 for the balance of the Term
    of this Agreement shall be due and payable upon termination.

         5.4  DEFINITION

         "Good reason", within the meaning of this Agreement, means after a
    "change of control," circumstances which, (a) in the reasonable judgment of
    Employee, constitute a material reduction in the Employee's job title,
    perquisites, duties, authority, amenities, benefits or responsibilities; or
    (b) require the Employee regularly to perform services at a location more
    than twenty-five (25) miles distant from the present location of
    Corporation in Concord, Massachusetts, without his consent.

                                         -4-
<PAGE>


         5.5  SURVIVAL.  The provisions of Sections 8, 9 and 10 shall survive
the termination of this Agreement.

    6.   PAYMENTS AFTER DISABILITY

    The Corporation shall pay to the Employee, or to his legal representative,
the amounts payable pursuant to subsection 3.1 during any period of partial or
total disability hereunder until the first to occur of (a) one year after the
date of the Employee's death, or (b) the end of the term of this Agreement.  In
the event of partial disability, Employee shall exert reasonable effort to
perform such services thereunder as his disability will permit.  The payments
made for such disability hereunder shall be reduced by the amount of any wage
continuation insurance payments payable to the Employee or his representative
during such period on the basis of any disability insurance coverage paid for by
the Corporation.  

    8.   NON-COMPETE.

         8.1  The Employee agrees to devote his entire business time, attention
and energies to the business and interests of the Corporation during the
Employment Period.      

         8.2  (i)  During the period of employment by the Corporation and for a
    period of eighteen (18) months after any termination of employment, the
    Employee agrees that he will not, directly or indirectly, alone or as a
    partner, officer, director, consultant, employee or direct or indirect
    owner (except a less than 2% stockholder of a public company) of any
    company or business organization, engage in any business activity which is
    directly or indirectly competitive with the products or services being
    developed, manufactured or sold by the Corporation, or any subsidiary or
    affiliate of the Corporation.  The term "directly or indirectly
    competitive" shall include the performance 

                                         -5-
<PAGE>

    of any services as an employee, consultant or otherwise in connection with
    any business activity which is competitive with or adverse to the products
    and services sold by the Corporation. Such limitations shall apply only
    within the continental United States, and in such foreign jurisdictions as
    to which there is a distributor or other representative of the Corporation
    or a subsidiary, division, licensee or affiliate of the Corporation in
    existence on the date of termination. 

              (ii) During the period of employment by the Corporation and for a
    period of eighteen months after any termination thereof, the Employee
    agrees that he will not directly or indirectly, either for himself or for
    any other person, business, partnership,  association, firm, company or
    corporation, call upon, solicit, divert or take away or attempt to solicit,
    divert or take away, any of the customers, business or prospective
    customers of the Corporation.  The Employee also agrees that during his
    employment with the Corporation and for a period of eighteen months
    thereafter, he will not solicit or discuss with any employee of the
    Corporation (a "Corporation Employee") the employment of such Corporation
    Employee by any business, firm, company, partnership, association,
    corporation or any other entity other than the Corporation.

         8.3  If any restriction set forth in this Section 8 is found by any
court of competent jurisdiction to be unenforceable because it extends for too
long a period of time or over too great a range of activities or in too broad a
geographic area, it shall be interpreted to extend only over the maximum period
of time, range of activities or geographic area as to which it may be
enforceable.

         8.4  The restrictions contained in this Section 8 are necessary for
the protection 

                                         -6-
<PAGE>


of the business and goodwill of the Corporation and are considered by the
Employee to be reasonable for such purpose.  The Employee agrees that any breach
of this Section 8 will cause the Corporation substantial and irrevocable damage
and therefore, in the event of any such breach, in addition to such other
remedies which may be available, the Corporation shall have the right to seek
specific performance and injunctive relief.

    9.   NONDISCLOSURE.

         9.1  The Employee agrees that he will not at any time, whether during
or after the termination of his employment, reveal to any person, entity,
association or company any Proprietary or Confidential Information of the
Corporation, except as may be required in the ordinary course of performing his
duties as an employee of the Corporation (and then with due regard for continued
confidentiality) or as may be required by law, and he shall keep secret all
matters of such nature entrusted to him and shall not use or attempt to use any
such information in any manner for his own benefit or the benefit of others, or
as may injure or cause loss or damage to the Corporation.

         9.2  The Employee further agrees that during his employment he shall
not make, use, or permit to be used any notes, memoranda, drawings,
specifications, programs, data or other materials relating to any matter within
the scope of the business of the Corporation or concerning any of its dealings
or affairs otherwise than for the benefit of the Corporation.

         9.3   The Employee further agrees

              (i)      that he shall not, after the termination of his
    employment, use or permit to be used any such notes, memoranda, drawings,
    specifications, programs, data or other materials, it being agreed that any
    of the foregoing shall be and remain the sole 

                                         -7-

    termination of his employment he shall deliver all of the foregoing, and
    all copies thereof, to the Corporation;

              (ii)    that all files, letters, memoranda, reports, records,
    experimental and other data, sketches, drawings, molds, models, patterns,
    samples, laboratory notebooks, computer disks or other storage devices for
    information, any computer, program listings, or other written,
    photographic, or other tangible material containing or incorporating
    Proprietary Information, whether created by Employee or others, which shall
    come into Employee's custody or possession, shall be and are the exclusive
    property of the Corporation to be used only in the performance of
    Employee's duties for the Corporation;

              (iii)   that all such records or copies thereof and all tangible
    property of the Corporation in Employee's custody or possession shall be
    delivered to the Corporation, upon the earlier of a request by the
    Corporation or any termination of  employment; and

              (iv)    that after such delivery, Employee shall not retain any
    such records or copies thereof or any such tangible property, and Employee
    agrees to destroy any Proprietary Information that may be in his possession
    but stored on media (such as computer disks) that themselves are not
    property of the Corporation.

         9.4  Employee agrees that his obligation not to disclose or to use
information and records of the types set forth above (including knowhow), and
his obligation to return records, copies and tangible property set forth in

records, copies and tangible property of customers of the

Corporation or suppliers to the Corporation or other third parties who may have
disclosed or entrusted the same to the Corporation or to Employee in the course
of the Corporation's business.

         10.3 That any such Invention so required to be assigned shall be

                        AMENDED AND RESTATED CREDIT AGREEMENT


    AGREEMENT made as of this 1st day of October, 1997 between STARMET

("StarMet"), STARMET POWDERS, LLC, a Delaware limited liability corporation

NMI, CMI and Holdings, the "Borrowers") and STATE STREET BANK AND TRUST 
COMPANY, an FDIC insured Massachusetts chartered trust company ("Bank").

    WHEREAS, StarMet, CMI and the Bank are parties to a Credit Agreement 
dated as of March 31, 1995, as amended by a First Amendment to Credit 
Agreement dated as of June 30, 1995, a letter agreement dated as of September 
26, 1995, a Forbearance and Amendment Agreement dated as of January 11, 1996, 
a First Amendment to Forbearance and Amendment Agreement dated as of February 
15, 1996, a Second Amendment to Forbearance and Amendment Agreement dated as 
of June 4, 1996, a Second Amendment to Credit Agreement dated as of December 
24, 1996 and a Third Amendment to Credit Agreement dated as of August 7, 1997 
(the "Original Credit Agreement"); 

    WHEREAS, StarMet is engaged in a restructuring where certain of its 
business lines will be transferred to newly organized subsidiaries as 
described in a proxy statement dated August 26, 1997 (the "Proxy Statement")

    WHEREAS, the Borrowers and the Bank have agreed to amend and restate the 
existing credit facility described above so as to, among other things, add 
Powders, Speciality, AeroCast, ComCast, NMI, and Holdings as "Borrowers" 
under the Original Credit Agreement and continue to provide for revolving 
credit facilities to the Borrowers;

    NOW, THEREFORE, the parties agree as follows:

ARTICLE I.  AMOUNT AND TERMS OF THE CREDIT.

    Section 1.01.  The Credit.

    Subject to the terms and conditions hereof, and in reliance on the 
representations and warranties contained herein, Bank hereby establishes a 
credit facility in favor of the Borrowers 

<PAGE>

in the principal amount of $6,550,000  (the "Credit").  The Credit consists of a
revolving line of credit of $6,550,000 ("Revolving Credit").  

    Section 1.02.  The Revolving Credit.

    (a)  Amount.  Provided no Event of Default (as defined in Article V) or 
event which with the passage of time or notice, or both, would become an 
Event of Default has occurred and is continuing, each Borrower may from time 
to time from the date hereof up to February 28, 1998 (the "Maturity Date") 
borrow and reborrow from the Bank and the Bank shall advance funds under the 
Revolving Credit to such Borrower (an "Advance" or the "Advances"); provided 
that the aggregate of all Advances outstanding at any time shall not exceed 
$6,550,000 less the maximum aggregate liability of the Borrowers under any 
outstanding letters of credit issued prior to the date hereof or pursuant to 
this Credit Agreement (the "Maximum Credit"). 

    (b)  Revolving Credit Payment. The aggregate Advances outstanding at any 
time shall not exceed the Maximum Credit.  If the aggregate Advances 
outstanding at any time exceed such limit, then the Borrowers shall 
immediately pay such excess.  The Bank may, without prior notice to the 
Borrowers, charge any of their accounts under the control of the Bank to 
effect such payment.

    (c)  The Revolving Credit Note.  Amounts owed to Bank with respect to 
Advances made by Bank shall be evidenced by Bank's books and records and may, 
at the request of Bank, be further evidenced by a revolving credit note in 
the maximum principal amount of the Revolving Credit (the "Revolving Credit 
Note") in the form of Exhibit 1.02(d) hereto.  The unpaid principal balance 
of the Revolving Credit may be voluntarily prepaid in whole or in part during 
the continuation of the Revolving Credit without premium or penalty; provided 
that if the Revolving Credit is to be terminated by the Borrowers, thirty 
(30) days prior notice shall be given to Bank.  Upon termination, the 
Borrowers shall satisfy the provisions of Section 6.01.  The Revolving Credit 
Note is subject to mandatory repayments, as provided in Section 1.02(b).

    (d)  Interest.  Advances made by Bank shall bear interest prior to 
maturity or the occurrence of an Event of Default (computed on the basis of 
actual number of days elapsed over a 360 day year) on the unpaid principal 
balances outstanding from time to time at a rate per annum equal to the Prime 
Rate plus one-half percent (1/2%).  After the Maturity Date or the occurrence 
of an Event of Default, the unpaid principal balance shall bear interest at 
the Prime Rate plus five (5%) percent.  Interest shall be payable monthly in 
arrears on the first day of each month commencing on October 1, 1997.  The 
effective rate of interest shall change on each day the Prime Rate changes.

    (e)  Requests for Advances.  Each Advance shall be made on the Banking 
Day on which Bank receives notice from the Borrower if such notice is 
received prior to 11:00 a.m. 

                                          2
<PAGE>


Boston time on such Banking Day, and otherwise on the next Banking Day.  Each 
request for an Advance shall be made to Bank in writing or by telephone by a 
duly authorized representative of the Borrowers.  Bank may rely upon any 
telephone request which it believes is made by such a representative.  The 
Borrowers agree to indemnify and hold Bank harmless for any action, including 
the making of Advances hereunder, or loss or expense, taken or incurred by 
Bank in good faith reliance upon such telephone request.  At the time of the 
initial request for an Advance, the Borrowers shall have provided Bank with a 
Compliance Certificate substantially in the form of Exhibit 1.02(e) hereto 
("Compliance Certificate").  Bank shall be entitled to rely upon the most 
recent Compliance Certificate in its possession until it is superseded by 
another certificate.

    (f)  Expiration.  The Revolving Credit shall expire on the Maturity Date 
and all Advances then outstanding under the Revolving Credit shall be due and 
payable without notice on such date.  In the event Bank continues Advances 
after the Maturity Date without a written extension of the Maturity Date, (i) 
all such Advances shall be made within the sole discretion of Bank; (ii) the 
entire Revolving Credit shall be due on demand; and (iii) other than such 
Advances, the entire Revolving Credit shall earn interest at the rate 
specified to be earned after maturity in Section 1.02(d).

    (g)  Overadvances.  Bank may from time to time in its sole discretion 
permit Advances to exceed the limitations set forth in this Agreement, 
including, without limitation, (i) Advances in excess of the Maximum Credit, 
and (ii) Advances after the Maturity Date or the occurrence of an Event of 
Default. All such Advances shall be deemed part of the Credit secured by any 
collateral securing the Credit and supported by any credit enhancements 
supporting the Credit.  The making of an Advance on one or more occasion will 
not operate to limit, waive or otherwise modify any rights of Bank hereunder 
on any future occasion unless otherwise agreed in writing.

    (h)  Special Uses.  The Borrowers may request portions of the Revolving 
Credit in the form of letters of credit pursuant to Section 1.05 hereof.

    (i)  Use of Proceeds.  Proceeds from Advances only shall be used by the 
Borrowers for working capital purposes.

    Section 1.03. Agency.  

    Each of the Borrowers hereby appoints StarMet as its agent to take any 
action and perform any obligation under this Agreement.  The Bank may 
conclusively rely upon any action taken by StarMet as binding on all of the 
Borrowers.

                                          3

banking business in Boston, Massachusetts.

by the Borrowers to Bank pursuant to this Agreement.

reference thereto.

    Section 1.05.  Letters of Credit.

    (a)  Issuance Procedures.  Each Borrower may request and Bank will issue 
standby letters of credit (such letters of credit together with any letters 
of credit outstanding on the date hereof and any renewal of any such 
outstanding letter of credit, collectively "L/Cs") for the account of such 
requesting Borrower.  With each request, the requesting Borrower shall 
deliver to Bank an L/C application and L/C agreement together with the 
proposed form of such L/C (which, together with all schedules and exhibits 
thereto, shall be in form and substance satisfactory to Bank and its counsel) 
and such other certificates, documents and other papers and information as 
Bank may reasonably request.  Any foreign beneficiary must be satisfactory to 
Bank.  All L/C's (other than letters of credit which are outstanding on the 
date hereof and any renewal of any such outstanding letter of credit) must 
expire at least one day prior to the Maturity Date.  Within five Banking Days 
following receipt of the above-described documents in satisfactory form, Bank 
shall, provided that no Event of Default exists and no event exists which, 
with the giving of notice or passage of time, or both, would constitute an 
Event of Default, issue such L/C.

    (b)  Reimbursement.  The Borrowers agree to pay Bank on each date that 
any amount is drawn under an L/C, a sum equal to the amount so drawn. The 
Borrowers agree to pay on demand any and all reasonable expenses incurred by 
Bank in enforcing any rights under this Section 1.05.  In the event any L/C 
is payable in foreign currency, the Borrowers shall reimburse Bank at Bank's 
selling rate of exchange on the date such reimbursement is made.

    (c)  Commission. The Borrowers agree to pay Bank in advance two percent 
(2%) per year (prorated based upon the number of days from the issue date to 
the expiration date) of the face amount of any L/C issued or renewed after 
the date hereof, together with any transactional fees at the Bank's customary 
rates.

    (d)  Method of Payment.  Bank is authorized to obtain reimbursement by 
making Advances under the Revolving Credit.  Bank may make such Advance even 
if it causes the outstanding balance to exceed the limits set forth in 
Section 1.02(a) and the making of such Advance shall be an Event of Default 
under Article V.

    (e)  Amount. The aggregate amount of L/Cs outstanding at any time shall 
not exceed $3,550,000.

                                          5
<PAGE>

    Section 1.06.  Payment by the Company.

    All payments and prepayments of principal and interest due with respect 
to the Credit and all other sums due hereunder shall be made by the Borrowers 
in immediately available funds deposited with Bank.  Payments received by 
Bank after 11:00 a.m. Boston time shall be deemed received on the next 
succeeding Banking Day.  Bank is authorized to make all such payments by 
Advances under the Revolving Credit.

    Section 1.07.  Credit for Uncollected Items.

    Bank will give the Borrowers credit for uncollected items deposited with 
Bank (a) the next Banking Day for purposes of computing availability under 
the Revolving Credit and (b) two Banking Days after deposit for purposes of 
computing interest and fees with respect to the Credit.

    Section 1.08.  Facility Fee.

    On the first day of each month (and upon the day of termination if the 
Credit is terminated), the Borrowers shall pay Bank a facility fee of 
one-half percent (1/2%) per year of the unused portion of the Revolving 
Credit for the preceding month.

    Section 1.09.  Audit Expenses.

    The Borrowers shall pay Bank on demand Bank's customary and reasonable 
fees and expenses for audit reviews by employees of Bank (currently $400 per 
man-day plus out-of-pocket expenses).

    Section 1.10.  Closing Fee.

    On the date hereof, Bank shall earn a one-time closing fee ("Closing 
Fee") of $0.00.

ARTICLE II.  REPRESENTATIONS AND WARRANTIES.

    The Borrowers jointly and severally represent and warrant as follows:

    Section 2.01.  Corporate Existence and Power.

jurisdiction where the conduct of their respective businesses or the 
ownership of their respective properties require such licensing or

a material adverse effect on the business, finances or operations of such 
Borrower or any of its Subsidiaries.

    Section 2.02.  Subsidiaries.

    No failure to exercise, and no delay in exercising, on the part of Bank,

applied to the payment of such obligations regardless of the adequacy of 
other collateral.  Any sums due from any financing institution that may 
participate in the Credit or property of the Borrowers in the possession of 
such institution may be held as collateral security for the payment of the 
obligations of the Borrowers to Bank as if such institution had extended the 
Credit directly to the Borrowers and, after the occurrence of an 

                                          27

instance and either retroactively or prospectively) only by a consent or 
consents in writing signed by Bank.

    Section 6.10.  Counterparts.  

    This Agreement may be executed in any number of counterparts which 
together shall constitute one Agreement.

    Section 6.11.  Joint and Several Obligations.

    The obligations of the Borrowers hereunder and under any agreement or 
instrument executed in connection herewith, including the Notes, shall be 
joint and several; provided, however, that the obligations of any Borrower 
shall be limited to the maximum amount that can be incurred without rendering

agree that all rights and claims under or relating to the Original Credit 
Agreement have been terminated and waived and (i) Bank has no further 
obligations to StarMet and CMI thereunder, and (ii) StarMet and CMI have no 
further obligations to Bank thereunder, provided, however, that Section 6.02

the Bank of its rights and claims under Section 6.02 of the Original Credit 
Agreement.

    Section 6.13.  Guarantees.

performance of the obligations of StarMet to Bank under, arising from or 
relating to the Bonds issued in connection with the 1985 Trust Agreement, 
including without limitation, any guaranty of such Bonds by StarMet in favor 
of Bank.  The above guarantees are of payment and not collection.

    Section 6.14.  Confidentiality, etc.

    The Bank agrees to use reasonable precautions to keep confidential, in 
accordance with safe and sound banking practices, any non-public information 
supplied to it by the Borrowers pursuant to this Agreement which is 
identified by the Borrowers as being confidential at the time the same is 
delivered to the Bank, provided that nothing herein shall limit the 
disclosure of any such information (i) to the extent required by statute, 
rule, regulation or judicial process, (ii) to counsel for the Bank, (iii) to 
bank examiners, auditors or accountants, (iv) in connection with any

participant (or prospective assignee or participant) first executes and 
delivers to the respective Bank a confidentiality agreement, or (vi) to the 
extent it subsequently becomes public. The Bank may assign or sell 
participations in, all or any part of the Credit to another bank or other

                            Environmental Matters

StarMet is named as a Potentially Responsible Party (PRP) in regard to the 
Maxey Flats, Kentucky, Superfund Site.

StarMet has received a notice of responsibility letter from the state of 
Massachusetts in regards to a closed holding basin facility on its property 
in Concord, Massachusetts.  The basin facility and the Concord property have 
been classified as a priority disposal site, requiring remediation.  StarMet 
has entered into a contract with Zhargrus Environmental, Inc. for the 
disposal of any hazardous waste at the basin facility.

As part of the five-year relicensing process under the federal Nuclear 
Regulatory Commission (NRC), StarMet was reissued NRC licenses for both the 
Concord and Barnwell facilities.  The relicensing program is now being 
administered in Massachusetts by the Massachusetts Department of Public 
Health ("DPH"), and in the State of South Carolina by the South Carolina 
Department of Health and Environmental Control ("DHEC").  StarMet has 
approached both DPH and DHEC regarding (i) the transfer of the Concord 
license to StarMet NMI Corporation and (ii) changing the name of the Barnwell 
license to reflect CMI's change of name.

StarMet has had ongoing discussions with the these agencies regarding 
Decontamination and Decommissioning funding and financial assurance plans. At 
present, StarMet has posted letters of credit with each of DPH and DHEC in 
the respective amounts of (i) $750,000 for DPH and (ii) $2,800,000 and 
$73,024 for DHEC as security for Decontamination and Decommissioning expenses.

    NOW, THEREFORE, for good and valuable consideration, the receipt and 
sufficiency of which are hereby acknowledged, it is hereby agreed as follows:

    1.   Security Interest.  The Borrowers grant Bank a security interest 
("Security Interest") in all personal property and fixtures of the Borrowers, 
of every kind and description, tangible or intangible all wherever located 
and whether now existing or hereafter acquired or arising, including without

    2.   Obligations.  The Security Interest shall secure the following,

Borrower execute such statements and instruments and such Borrower does not 
so execute and deliver to Bank the subject statements and instruments within 
two days of such request.

    4.   Borrowers Places of Business.  The Borrowers jointly and severally 
represent and warrant that their respective places of business, chief 
executive office, the location where the records concerning their respective 
accounts and contract rights are located and the record owners of any real 
estate on which any of the Collateral is located are as set forth on Exhibit 
B attached hereto. The Borrowers agree to notify Bank of the addition or 
discontinuance of any place of business, chief executive office or any chance 
in the information contained on Exhibit B.  None of the Collateral shall be 
removed from the locations specified on Exhibit B other than sales in the 
ordinary course of business unless Bank is given thirty (30) days prior 
written notice of such removal, which notice shall state the location or 
locations to which the Collateral will be removed.  The Borrowers jointly 
represent and warrant that all of the Collateral presently is located at the 
locations set forth on Exhibit B and agrees that the Collateral will remain 
at such locations and at such other locations of which Bank receives notice 
in accordance with this Paragraph 4.

    5.   Name.  The Borrowers jointly represent and warrant that their 
precise legal names are set forth in the introduction to this Agreement and 
agree to notify Bank immediately of any change in such legal names.

    6.   Encumbrances.  Each Borrower represents and warrants that it has 
title to the Collateral in which it has rights and that there are no sums 
owed or claims, liens, security interests or other encumbrances against the 
Collateral other than those permitted by the Credit Agreement.  The Borrowers 
agree to notify Bank of any lien (except inchoate liens arising by the 
operation of law), security interest or other encumbrance securing, an 
obligation in excess of $50,000 against the Collateral (even though permitted 
by the Credit Agreement). Borrowers shall defend the Collateral against any 
claim, lien, security interest or other encumbrance adverse to Bank, except 
for liens permitted by the Credit Agreement.

    7.   Maintenance of Collateral.  The Borrowers shall preserve the 
Collateral for the benefit of Bank.  Without limiting the generality of the 
foregoing, the Borrowers shall:

         (a)  sell inventory only in the ordinary course of business;
         (b)  preserve all beneficial contract rights to the extent
commercially reasonable;
         (c)  take commercially reasonable steps to collect all accounts; and
         (d)  pay all taxes, assessments or other charges on the Collateral
when due, except to the extent otherwise permitted by the Credit Agreement.

    8.   Collection.  Bank may communicate with account debtors in order to
verify the existence, amount and terms of any accounts or contract rights.  The
Borrowers will maintain 

                                      3
<PAGE>

such lockbox or blocked accounts as Bank shall specify.  All proceeds of 
Collateral in the possession of the officers, employees or agents of the 
Borrowers shall be held in trust for the benefit of Bank.  All proceeds of 
Collateral including, without limitation, collections from accounts and 
proceeds from cash sales of Collateral shall be deposited into such lockbox 
or blocked accounts or remitted directly to Bank.

    At any time after the occurrence and during the continuance of an Event 
of Default, Bank (a) may notify account debtors of the Security Interest and 
require that payments on .accounts and returns of goods be made directly to 
Bank; (b) may require the Borrowers to notify their respective account 
debtors and indicate on all billings that payments and returns are to be made 
directly to Bank; and (c) may collect, compromise, endorse, sell or otherwise 
deal with the accounts or proceeds thereof in its own name or in the name of 
any Borrower.

    If any of the Borrowers' accounts or contract rights arise out of 
contracts with a governmental body subject to the Federal Assignment of 
Claims Act or a similar statute, upon request of Bank, the Borrowers shall 
execute any instruments and take any action required by law to ensure that 
all monies due and to become due under such contract shall be paid directly 
to Bank.

    9.   Insurance.  The Borrowers shall maintain insurance covering the 
Collateral as provided in the Credit Agreement.  All such insurance policies 
with respect to Collateral shall be written so as to be payable in the event 
of loss directly to Bank, shall provide for thirty (30) days prior written 
notice to Bank of cancellation or modification, and shall contain an 
endorsement providing that the insurer cannot withhold payment to Bank on 
account of any action by the Borrowers.  Bank is hereby irrevocably appointed 
as attorney-in-fact (which power is coupled with an interest) to collect the 
proceeds of such insurance, to settle any claims with the insurers in the 
event of loss or damage, to endorse settlement drafts, to cancel, assign or 
surrender any insurance policies; provided, however, that Bank will not 
exercise the foregoing power of attorney except after the occurrence and 
during the continuance of an Event of Default.

    10.  Additional Provisions Concerning the Collateral.
         (a)  Each Borrower hereby irrevocably appoints Bank its 
attorney-in-fact (which such power of attorney is coupled with an interest) 
with full authority in the place and stead of such Borrower and in the name 
thereof, from time to time after the occurrence and during the continuation 
of an Event of Default, to take any of the following actions or execute any 
of the following instruments which Bank may deem necessary or advisable to 
accomplish the purposes of this Agreement: (i) to ask, demand, collect, sue 
for, recover, compound, receive, and give acquittance and receipts for moneys 
due and to become due under or in respect of any of the Collateral; (ii) to 
receive, endorse, and collect any checks, drafts, letters of credit, or other 
instruments, documents, and chattel paper in connection with clause (i) 
above; (iii) to sign each such Borrower's name on any invoice or bill of 
lading relating, to any account, on drafts against customers, on schedules 
and assignments of accounts, on notices of assignment, financing statements 
and other public records, on verification of accounts and on 

                                      4
<PAGE>

notices to customers (including notices directing customers to make payment 
directly to Bank); (iv) to notify the post office authorities to change the 
address for delivery of its mail to an address designated by Bank; (v) to 
receive, open and process all mail addressed to any Borrower; (vi) to send 
requests for verification of accounts to customers; and (vii) to file any 
claims or take any action or institute any Proceedings which Bank may deem 
necessary or desirable for the collection of any of the Collateral or 
otherwise to enforce the rights of Bank with respect to any of the 
Collateral.  Bank agrees that it will exercise the foregoing power of 
attorney in a commercially reasonable manner.

         (b)  If any Borrower fails to perform any agreement contained 
herein, Bank may itself perform, or cause performance of, such agreement or 
obligation, and the reasonable costs and expenses of Bank incurred in 
connection therewith shall be payable by the Borrowers on demand and shall be 
secured by the Collateral.  All such expenditures shall bear interest at the 
Prime Rate (as defined in the Credit Agreement) plus five percent (5%).

         (c)  The powers conferred on Bank under this Agreement are solely to 
protect its interest in the Collateral and shall not impose any duty upon 
Bank to exercise any such powers.  Except for the safe custody of any 
Collateral in its possession and the accounting for moneys actually received 
by it hereunder, Bank shall have no duty as to any Collateral or as to the 
taking of any necessary steps to preserve rights against prior parties or any 
other rights pertaining to any Collateral.

    11.  Default.  If any one or more of the following events (herein 
referred to as "Events of Default") shall occur:

         (a)  Any Borrower shall fail to perform or observe any provision of
this Agreement and such default shall continue for a period of seven (7) days
after written notice from Bank; or
         (b)  An Event of Default shall have occurred under Article V of the
Agreement;

    then, Bank shall have (a) the right to accelerate any or all of the 
Obligations, and (b) all of the rights and remedies set forth in Section 12 
below.

    12.  Remedies.  Bank shall have all of the rights and remedies of a 
secured party under the Uniform Commercial Code and shall have full power and 
authority to sell or otherwise dispose of the Collateral or any part thereof. 
 Any such sale or other disposition, subject to the provisions of applicable 
law, may be by public or private proceedings and may be made by one or more 
contracts, as a unit or in parcels, at such time and place, by such method, 
in such manner and on such terms as Bank may determine.  Except as required 
by law, such sale or other disposition may be made without advertisement or 
notice of any kind or to any person.  Where reasonable notification of the 
time or place of such sale or other disposition is required by law, such 
requirement shall have been met if such notice is delivered as provided in 
the Agreement, at least ten (10) days before the time of such sale or other 

                                      5
<PAGE>

disposition.  Upon notice from Bank, the Borrowers shall assemble the 
Collateral at a time and place specified by Bank.  To the extent permitted by 
law, Bank or any other holder of the Obligations may buy any or all of the 
Collateral upon any sale thereof.  To the extent permitted by law, upon any 
such sale or sales, the Collateral so purchased shall be held by the 
purchaser absolutely free from any claims or rights of whatsoever kind or 
nature, including any equity of redemption or any similar rights, all such 
equity of redemption and any similar rights being hereby expressly waived and 
released by the Borrowers.  In the event any consent, approval or 
authorization of any governmental agency shall be necessary to effectuate any 
such sale or sales, the Borrowers shall execute, as necessary, all 
applications or other instruments as may be required.

    At any time after the occurrence of an Event of Default, Bank may 
commence proceedings in any court of competent jurisdiction for the 
appointment of a receiver (which term shall include a receiver-manager) of 
the Collateral or of any part thereof.  At any time after the occurrence of 
an Event of Default, Bank may, if permitted without the commencement of a 
proceeding, appoint any person to be a receiver of the Collateral or any part 
thereof and may remove any receiver so appointed and appoint another in his 
stead.  Any such receiver appointed by Bank, or a court at the request of 
Bank, shall have power (i) to take possession of the Collateral or any part 
thereof; (ii) to carry on the business of the Borrowers; (iii) to borrow 
money on the security of the Collateral for the maintenance, preservation or 
protection of the Collateral or any part thereof or for the carrying on of 
the business of the Borrowers; and (iv) to sell, lease or otherwise dispose 
of the whole or any part of the Collateral at public auction, by public 
tender or by private sale, either for cash or upon credit, at such time and 
upon such terms and conditions as the receiver may determine; provided that 
Bank shall not be in any way responsible for any misconduct or negligence of 
any such receiver.

    Upon written notice to the Borrowers, the Borrowers shall execute and 
deliver to Bank a written assignment or assignments of all of their 
respective rights under any lease of Collateral.  If the consent of the 
lessor is required with respect to any assignment or hereunder, such 
assignment shall not be effective until such consent is obtained.  Each 
Borrower hereby irrevocably appoints Bank its attorney-in-fact (which power 
is coupled with an interest) to execute assignments and subleases in favor of 
Bank, provided that Bank shall exercise this power only after Bank has 
requested that such Borrower execute such assignment and it does not so 
execute and deliver to Bank the subject assignment within two days of such 
request.

    13.  Proceeds.  After deducting all reasonable costs and expenses of 
collection, custody, sale or other disposition or delivery (including legal 
costs and reasonable attorneys' fees) and all other charges due against the 
Collateral, the residue of the proceeds of any such sale or other disposition 
shall be applied to the payment of the Obligations and any surplus shall be 
returned to the Borrowers, except as otherwise provided by law.  The 
Borrowers shall be liable for any deficiency in payment of the Obligations, 
including all reasonable costs and expenses of collection, custody, sale or 
other disposition or delivery and all other charges due against the 
Collateral, as hereinbefore enumerated.

                                      6

<PAGE>

    14.  Waivers.  To the extent permitted by law, the Borrowers and any 
third party providing credit enhancement with respect to the Obligations 
("Secondary Party") hereby waive demand for payment, notice of dishonor or 
protest, rights of redemption, prior notice of the appointment of a receiver 
and all other notices of any kind except notices specifically required hereby 
or by the Credit Agreement.  Bank may modify the liability of any Secondary 
Party and release any Collateral provided by such Secondary Party without 
giving, notice to the Borrowers or any other Secondary Party.  Such 
modifications, changes, renewals, releases or other actions shall in no way 
affect the obligations of the Borrowers or any Secondary Party hereunder.

    15.  Expenses.  The Borrowers agree to pay, indemnify and hold harmless 
Bank and the nominees of Bank from and against all costs and expenses 
(including, taxes, if any) arising out of or incurred in connection with the 
administration and sale of Collateral and all reasonable costs and expenses 
(including reasonable legal fees) incurred by Bank in connection with the 
negotiation, preparation, execution, amendment, interpretation, termination 
or enforcement of this Agreement.

    16.  Setoff.  Any sums due from Bank to any Borrower or any property of 
any Borrower in the possession of Bank may be held and treated as Collateral 
and, after the occurrence of an Event of Default, may be applied to the 
payment of the Obligations regardless of the adequacy of the Collateral.

    17.  Modification. This Agreement may be modified or amended only in 
writing signed by each of the parties hereto.

    18.  Notices.  All notices and other communications hereunder shall be 
deemed to have been sufficiently given if delivered as provided in the Credit 
Agreement.

    19.  Waivers.  No course of dealing between the Borrowers and Bank, nor 
any delay in exercising, on the part of Bank, any right, power or privilege 
hereunder, shall operate as a waiver thereof; nor shall any single or partial 
exercise of any right, power or privilege hereunder preclude any other or 
further exercise thereof or the exercise of any other right, power or 
privilege. The rights and remedies hereunder are cumulative and are in 
addition to, and not exclusive of, any rights or remedies provided by law.

    20.  Governing Law; Binding Effect; Counterparts.  This Agreement shall 
be construed in accordance with and governed by the laws of the Commonwealth 
of Massachusetts.  This Agreement shall be binding upon and inure to the 
benefit of the parties hereto and their respective successors and assigns, 
including any other holder or holders of any Obligations and may be executed 
in two or more counterparts, each of which shall together constitute one and 
the same agreement.

    21.  Severability.  The invalidity or unenforceability of any provision 
hereof shall way affect the validity or enforceability of any other provision 
hereof.

                                      7

                                 EMPLOYMENT AGREEMENT

    This Agreement is made effective as of the first day of October, 1997, by
and between Starmet Corporation, a Massachusetts corporation with its principal
office in Concord, Massachusetts (the "Corporation"), and William T. Nachtrab
(the "Employee") of Maynard, Massachusetts.

    WHEREAS, the Corporation is engaged in the business of developing and
marketing metallurgical and other products; and

    WHEREAS, the Employee is employed by the Corporation as its Vice President,

    WHEREAS, the parties hereto wish to describe the terms under which the

    NOW, THEREFORE, in consideration of the foregoing promises and the mutual
agreements herein contained, the parties hereto agree as follows:

    1.   Employment

    The parties agree to continued employment of the Employee by the
Corporation during the Term of this Agreement and according to the terms and
conditions hereof.

    3.   Compensation

         3.1  Initial Compensation

         The Employee's compensation shall be at the minimum annual rate of
    $136,000 for the Term of this Agreement.

         3.2  Payments

         Such compensation shall be paid to the Employee on a weekly, bi-weekly
    or monthly basis, consistent with the Corporation's normal practice in
    paying compensation to its other executive employees.

         3.3  Increases

         The Board of Directors or President may, from time to time during the
    Term of this Agreement, review compensation and such compensation may be
    increased (but not decreased below the levels provided in this Agreement)

    and of the Corporation and the salary levels prevailing generally for
    positions of comparable responsibility.

         3.4  Bonuses

         In addition to the foregoing initial compensation, the Corporation may
    pay the Employee a bonus in any year in such amount as may be determined by

<PAGE>


         4.1  Benefit Plans

         The Corporation shall include the Employee in all of its benefit
    plans, including stock option plans, vacation, pension benefits and major
    medical, accident and health insurance, while he remains an active employee

    the coverage provided to other executive employees of the Corporation.

         4.2  No Reduction of Benefits

         The Corporation shall not eliminate or reduce benefits in effect on
    the date hereof.

    5.   Termination

         5.1  Termination Payments

         The Board of Directors of the Corporation acting on behalf of the
    Corporation and after notice and an opportunity to be heard, may terminate
    the Employee's employment hereunder if a majority of the whole number of
    Directors then in office determines, in good faith, that:

         (a)  the Employee has willfully refused to perform substantially 
    all of the services required of him hereunder; or

         (b)  the Employee has been convicted of a crime of moral turpitude.
    In such event, or in the event of voluntary termination by the Employee
    without "good reason," as herein defined, the Employee's right to all
    future payments set forth in Article 3 hereof shall cease; or

         (c)  prior to a "change of control," as herein defined, by either
    party on twelve months' written notice to the other.  "Change of control"
    shall mean (i) a change (other 


                                         -3-
<PAGE>

    than a change resulting from death, retirement or disability) in the
    identity of a majority of the Board of Directors of the Corporation or in
    the identity of both the President and Chairman of the Board of the
    Corporation, or (ii) the occurrence of a transaction or event which a
    majority of directors of the Corporation in office immediately prior to
    such transaction deem to involve a change of control.

         5.2  Death

         In the event of the death of the Employee, payments set forth in
    subsection 3.1 shall be made to the executor or administrator or other
    personal representative of the decedent and shall be continued until the
    earlier of one year from the date of death of the Employee or the end of
    the Term of this Agreement.

         5.3  Other Terminations

         In the event of termination by the Corporation other than pursuant to
    subsection 5.1 or of termination by the Employee for good reason, the
    amounts payable pursuant to said subsection 3.1 for the balance of the Term
    of this Agreement shall be due and payable upon termination.

         5.4  Definition

         "Good reason", within the meaning of this Agreement, means "after a
    change of control," which, in the reasonable judgment of Employee,
    constitute a material reduction in the Employee's job title, perquisites,
    duties, authority, amenities, benefits or responsibilities; or (b) require
    the Employee regularly to perform services at a location more than
    twenty-five (25) miles distant from the present location of Corporation in
    Concord, Massachusetts, without his consent.

                                         -4-

         5.5  Survival.  The provisions of Sections 8, 9 and 10 shall survive 
the termination of this Agreement.

    6.   Payments After Disability

    The Corporation shall pay to the Employee, or to his legal representative,
the amounts payable pursuant to subsection 3.1 during any period of partial or
total disability hereunder until the first to occur of (a) one year after the
date of the Employee's death, or (b) the end of the term of this Agreement.  In
the event of partial disability, Employee shall exert reasonable effort to
perform such services thereunder as his disability will permit.  The payments
made for such disability hereunder shall be reduced by the amount of any wage
continuation insurance payments payable to the Employee or his representative
during such period on the basis of any disability insurance coverage paid for by
the Corporation.  

    8.   Non-Compete.

         8.1  The Employee agrees to devote his entire business time, attention
and energies to the business and interests of the Corporation during the
Employment Period.

         8.2  (i)   During the period of employment by the Corporation and for
    a period of eighteen (18) months after any termination of employment, the
    Employee agrees that he will not, directly or indirectly, alone or as a
    partner, officer, director, consultant, employee or direct or indirect
    owner (except a less than 2% stockholder of a public company) of any
    company or business organization, engage in any business activity which is
    directly or indirectly competitive with the products or services being
    developed, manufactured or sold by the Corporation, or any subsidiary or
    affiliate of the Corporation.  The term "directly or indirectly
    competitive" shall include the performance 

                                         -5-
<PAGE>

    of any services as an employee, consultant or otherwise in connection with
    any business activity which is competitive with or adverse to the products
    and services sold by the Corporation. Such limitations shall apply only
    within the continental United States, and in such foreign jurisdictions as
    to which there is a distributor or other representative of the Corporation
    or a subsidiary, division, licensee or affiliate of the Corporation in
    existence on the date of termination. 

              (ii)  During the period of employment by the Corporation and for
    a period of eighteen months after any termination thereof, the Employee
    agrees that he will not directly or indirectly, either for himself or for
    any other person, business, partnership,  association, firm, company or
    corporation, call upon, solicit, divert or take away or attempt to solicit,
    divert or take away, any of the customers, business or prospective
    customers of the Corporation.  The Employee also agrees that during his
    employment with the Corporation and for a period of eighteen months
    thereafter, he will not solicit or discuss with any employee of the
    Corporation (a "Corporation Employee") the employment of such Corporation
    Employee by any business, firm, company, partnership, association,
    corporation or any other entity other than the Corporation.

         8.3  If any restriction set forth in this Section 8 is found by any
court of competent jurisdiction to be unenforceable because it extends for too
long a period of time or over too great a range of activities or in too broad a
geographic area, it shall be interpreted to extend only over the maximum period
of time, range of activities or geographic area as to which it may be
enforceable.

         8.4  The restrictions contained in this Section 8 are necessary for
the protection 

                                         -6-
<PAGE>

of the business and goodwill of the Corporation and are considered by the
Employee to be reasonable for such purpose.  The Employee agrees that any breach
of this Section 8 will cause the Corporation substantial and irrevocable damage
and therefore, in the event of any such breach, in addition to such other
remedies which may be available, the Corporation shall have the right to seek
specific performance and injunctive relief.

    9.   Nondisclosure.

         9.1  The Employee agrees that he will not at any time, whether during
or after the termination of his employment, reveal to any person, entity,
association or company any Proprietary or Confidential Information of the
Corporation, except as may be required in the ordinary course of performing his
duties as an employee of the Corporation (and then with due regard for continued
confidentiality) or as may be required by law, and he shall keep secret all
matters of such nature entrusted to him and shall not use or attempt to use any
such information in any manner for his own benefit or the benefit of others, or
as may injure or cause loss or damage to the Corporation.

         9.2  The Employee further agrees that during his employment he shall
not make, use, or permit to be used any notes, memoranda, drawings,
specifications, programs, data or other materials relating to any matter within
the scope of the business of the Corporation or concerning any of its dealings
or affairs otherwise than for the benefit of the Corporation.

         9.3   The Employee further agrees
              (i)   that he shall not, after the termination of his employment,
    use or permit to be used any such notes, memoranda, drawings,
    specifications, programs, data or other materials, it being agreed that any
    of the foregoing shall be and remain the sole 

                                         -7-
<PAGE>

    and exclusive property of the Corporation and that immediately upon
    termination of his employment he shall deliver all of the foregoing, and
    all copies thereof, to the Corporation;

              (ii)  that all files, letters, memoranda, reports, records,
    experimental and other data, sketches, drawings, molds, models, patterns,
    samples, laboratory notebooks, computer disks or other storage devices for
    information, any computer, program listings, or other written,
    photographic, or other tangible material containing or incorporating
    Proprietary Information, whether created by Employee or others, which shall
    come into Employee's custody or possession, shall be and are the exclusive
    property of the Corporation to be used only in the performance of
    Employee's duties for the Corporation;

              (iii) that all such records or copies thereof and all
    tangible property of the Corporation in Employee's custody or possession
    shall be delivered to the Corporation, upon the earlier of a request by the
    Corporation or any termination of  employment; and

              (iv)  that after such delivery, Employee shall not retain any such
    records or copies thereof or any such tangible property, and Employee
    agrees to destroy any Proprietary Information that may be in his possession
    but stored on media (such as computer disks) that themselves are not
    property of the Corporation.

         9.4  Employee agrees that his obligation not to disclose or to use
information and records of the types set forth above (including knowhow), and
his obligation to return records, copies and tangible property set forth in
paragraph (b) above, also extends to such knowhow and other information,
records, copies and tangible property of customers of the 

                                         -8-

Corporation or suppliers to the Corporation or other third parties who may have
disclosed or entrusted the same to the Corporation or to Employee in the course
of the Corporation's business.

         The Board of Directors of the Corporation acting on behalf of the
    Corporation and after notice and an opportunity to be heard, may terminate
    the Employee's employment hereunder if a majority of the whole number of
    Directors then in office determines, in good faith, that:

         (a)   the Employee has willfully refused to perform substantially all 
    of the services required of him hereunder; or

         (b)   the Employee has been convicted of a crime of moral turpitude.
    In such event, or in the event of voluntary termination by the Employee
    without "good reason," as herein defined, the Employee's right to all
    future payments set forth in Article 3 hereof shall cease; or

         (c)    prior to a "change of control," as herein defined, by either
    party on twelve months' written notice to the other.  "Change of control"
    shall mean (i) a change (other 

                                     3
<PAGE>

    than a change resulting from death, retirement or disability) in the
    identity of a majority of the Board of Directors of the Corporation or in
    the identity of both the President and Chairman of the Board of the
    Corporation, or (ii) the occurrence of a transaction or event which a
    majority of directors of the Corporation in office immediately prior to
    such transaction deem to involve a change of control.

         5.2  Death

         In the event of the death of the Employee, payments set forth in
    subsection 3.1 shall be made to the executor or administrator or other

    the Term of this Agreement.

         5.3  Other Terminations

         In the event of termination by the Corporation other than pursuant to
    subsection 5.1 or of termination by the Employee for good reason, the
    amounts payable pursuant to said subsection 3.1 for the balance of the Term
    of this Agreement shall be due and payable upon termination.

         5.4  Definition

         "Good reason", within the meaning of this Agreement, consists of  (a)
    circumstances which, in the reasonable judgment of Employee, constitute a
    material reduction in the Employee's job title, perquisites, duties,
    authority, amenities, benefits or responsibilities; or (b) require the
    Employee regularly to perform services at a location more than twenty-five
    (25) miles distant from the present location of Corporation in Concord,
    Massachusetts, without his consent.

<PAGE>

              5.5  Survival.  The provisions of Sections 8, 9 and 10 shall
survive the termination of this Agreement.

    6.   Payments After Disability

    The Corporation shall pay to the Employee, or to his legal 
representative, the amounts payable pursuant to subsection 3.1 during any 
period of partial or total disability hereunder until the first to occur of 
(a) one year after the date of the Employee's death, or (b) the end of the 
term of this Agreement.  In the event of partial disability, Employee shall 
exert reasonable effort to perform such services thereunder as his disability 
will permit.  The payments made for such disability hereunder shall be 
reduced by the amount of any wage continuation insurance payments payable to 
the Employee or his representative during such period on the basis of any 
disability insurance coverage paid for by the Corporation.  

    8.   Non-Compete.

         8.1  The Employee agrees to devote his entire business time, 
attention and energies to the business and interests of the Corporation 
during the Employment Period.      

         8.2  (i)  During the period of employment by the Corporation and for a
    period of eighteen (18) months after any termination of employment, the
    Employee agrees that he will not, directly or indirectly, alone or as a
    partner, officer, director, consultant, employee or direct or indirect
    owner (except a less than 2% stockholder of a public company) of any
    company or business organization, engage in any business activity which is
    directly or indirectly competitive with the products or services being
    developed, manufactured or sold by the Corporation, or any subsidiary or
    affiliate of the Corporation.  The term "directly or indirectly
    competitive" shall include the performance 

                                     5
<PAGE>

    of any services as an employee, consultant or otherwise in connection with
    any business activity which is competitive with or adverse to the products
    and services sold by the Corporation. Such limitations shall apply only
    within the continental United States, and in such foreign jurisdictions as
    to which there is a distributor or other representative of the Corporation
    or a subsidiary, division, licensee or affiliate of the Corporation in
    existence on the date of termination. 

              (ii) During the period of employment by the Corporation and for a
    period of eighteen months after any termination thereof, the Employee
    agrees that he will not directly or indirectly, either for himself or for
    any other person, business, partnership,  association, firm, company or
    corporation, call upon, solicit, divert or take away or attempt to solicit,
    divert or take away, any of the customers, business or prospective
    customers of the Corporation.  The Employee also agrees that during his
    employment with the Corporation and for a period of eighteen months
    thereafter, he will not solicit or discuss with any employee of the
    Corporation (a "Corporation Employee") the employment of such Corporation
    Employee by any business, firm, company, partnership, association,
    corporation or any other entity other than the Corporation.

         8.3  If any restriction set forth in this Section 8 is found by any
court of competent jurisdiction to be unenforceable because it extends for too
long a period of time or over too great a range of activities or in too broad a
geographic area, it shall be interpreted to extend only over the maximum period
of time, range of activities or geographic area as to which it may be
enforceable.

         8.4  The restrictions contained in this Section 8 are necessary for
the protection 
                                     6
<PAGE>

of the business and goodwill of the Corporation and are considered by the 
Employee to be reasonable for such purpose.  The Employee agrees that any 
breach of this Section 8 will cause the Corporation substantial and 
irrevocable damage and therefore, in the event of any such breach, in 
addition to such other remedies which may be available, the Corporation shall 
have the right to seek specific performance and injunctive relief.

    9.   Nondisclosure.

         9.1  The Employee agrees that he will not at any time, whether 
during or after the termination of his employment, reveal to any person, 
entity, association or company any Proprietary or Confidential Information of 
the Corporation, except as may be required in the ordinary course of 
performing his duties as an employee of the Corporation (and then with due 
regard for continued confidentiality) or as may be required by law, and he 
shall keep secret all matters of such nature entrusted to him and shall not 
use or attempt to use any such information in any manner for his own benefit 
or the benefit of others, or as may injure or cause loss or damage to the 
Corporation.

         9.2  The Employee further agrees that during his employment he shall 
not make, use, or permit to be used any notes, memoranda, drawings, 
specifications, programs, data or other materials relating to any matter 
within the scope of the business of the Corporation or concerning any of its 
dealings or affairs otherwise than for the benefit of the Corporation.

         9.3   The Employee further agrees

              (i)   that he shall not, after the termination of his employment,
    use or permit to be used any such notes, memoranda, drawings,
    specifications, programs, data or other materials, it being agreed that any
    of the foregoing shall be and remain the sole 

                                     7

    and exclusive property of the Corporation and that immediately upon
    termination of his employment he shall deliver all of the foregoing, and
    all copies thereof, to the Corporation;

              (ii) that all files, letters, memoranda, reports, records,
    experimental and other data, sketches, drawings, molds, models, patterns,
    samples, laboratory notebooks, computer disks or other storage devices for
    information, any computer, program listings, or other written,
    photographic, or other tangible material containing or incorporating
    Proprietary Information, whether created by Employee or others, which shall
    come into Employee's custody or possession, shall be and are the exclusive
    property of the Corporation to be used only in the performance of
    Employee's duties for the Corporation;

              (iii)     that all such records or copies thereof and all
    tangible property of the Corporation in Employee's custody or possession
    shall be delivered to the Corporation, upon the earlier of a request by the
    Corporation or any termination of  employment; and

              (iv) that after such delivery, Employee shall not retain any such
    records or copies thereof or any such tangible property, and Employee
    agrees to destroy any Proprietary Information that may be in his possession
    but stored on media (such as computer disks) that themselves are not
    property of the Corporation.

         9.4  Employee agrees that his obligation not to disclose or to use 
information and records of the types set forth above (including knowhow), and 
his obligation to return records, copies and tangible property set forth in

records, copies and tangible property of customers of the

<PAGE>

Corporation or suppliers to the Corporation or other third parties who may 
have disclosed or entrusted the same to the Corporation or to Employee in the 
course of the Corporation's business.

         10.3 That any such Invention so required to be assigned shall be

in Section 101 of the United States Copyright Act of 1976, as amended;

                                     9

    of this Agreement shall be due and payable upon termination.

         5.4  Definition

         "Good reason", within the meaning of this Agreement, means "after a
    change of control," circumstances which, (a) in the reasonable judgment of
    Employee, constitute a material reduction in the Employee's job title,
    perquisites, duties, authority, amenities, benefits or responsibilities; or
    (b) require the Employee regularly to perform services at a location more
    than twenty-five (25) miles distant from the present location of

         5.5  Survival.  The provisions of Sections 8, 9 and 10 shall survive 
the termination of this Agreement.

    6.   Payments After Disability

    The Corporation shall pay to the Employee, or to his legal representative,
the amounts payable pursuant to subsection 3.1 during any period of partial or
total disability hereunder until the first to occur of (a) one year after the
date of the Employee's death, or (b) the end of the term of this Agreement.  In
the event of partial disability, Employee shall exert reasonable effort to
perform such services thereunder as his disability will permit.  The payments
made for such disability hereunder shall be reduced by the amount of any wage
continuation insurance payments payable to the Employee or his representative
during such period on the basis of any disability insurance coverage paid for by
the Corporation.  

    8.   Non-Compete.

         8.1  The Employee agrees to devote his entire business time, attention
and energies to the business and interests of the Corporation during the
Employment Period.      

         8.2  (i)  During the period of employment by the Corporation and for a
    period of eighteen (18) months after any termination of employment, the
    Employee agrees that he will not, directly or indirectly, alone or as a
    partner, officer, director, consultant, employee or direct or indirect
    owner (except a less than 2% stockholder of a public company) of any
    company or business organization, engage in any business activity which is
    directly or indirectly competitive with the products or services being
    developed, manufactured or sold by the Corporation, or any subsidiary or
    affiliate of the Corporation.  The term "directly or indirectly
    competitive" shall include the performance 

                                         -5-
<PAGE>

    of any services as an employee, consultant or otherwise in connection with
    any business activity which is competitive with or adverse to the products
    and services sold by the Corporation. Such limitations shall apply only
    within the continental United States, and in such foreign jurisdictions as
    to which there is a distributor or other representative of the Corporation
    or a subsidiary, division, licensee or affiliate of the Corporation in
    existence on the date of termination. 

              (ii) During the period of employment by the Corporation and for a
    period of eighteen months after any termination thereof, the Employee
    agrees that he will not directly or indirectly, either for himself or for
    any other person, business, partnership,  association, firm, company or
    corporation, call upon, solicit, divert or take away or attempt to solicit,
    divert or take away, any of the customers, business or prospective
    customers of the Corporation.  The Employee also agrees that during his
    employment with the Corporation and for a period of eighteen months
    thereafter, he will not solicit or discuss with any employee of the
    Corporation (a "Corporation Employee") the employment of such Corporation
    Employee by any business, firm, company, partnership, association,
    corporation or any other entity other than the Corporation.

         8.3  If any restriction set forth in this Section 8 is found by any
court of competent jurisdiction to be unenforceable because it extends for too
long a period of time or over too great a range of activities or in too broad a
geographic area, it shall be interpreted to extend only over the maximum period
of time, range of activities or geographic area as to which it may be
enforceable.

         8.4  The restrictions contained in this Section 8 are necessary for
the protection 

                                         -6-
<PAGE>

of the business and goodwill of the Corporation and are considered by the
Employee to be reasonable for such purpose.  The Employee agrees that any breach
of this Section 8 will cause the Corporation substantial and irrevocable damage
and therefore, in the event of any such breach, in addition to such other
remedies which may be available, the Corporation shall have the right to seek
specific performance and injunctive relief.

    9.   Nondisclosure.

         9.1  The Employee agrees that he will not at any time, whether during
or after the termination of his employment, reveal to any person, entity,
association or company any Proprietary or Confidential Information of the
Corporation, except as may be required in the ordinary course of performing his
duties as an employee of the Corporation (and then with due regard for continued
confidentiality) or as may be required by law, and he shall keep secret all
matters of such nature entrusted to him and shall not use or attempt to use any
such information in any manner for his own benefit or the benefit of others, or
as may injure or cause loss or damage to the Corporation.

         9.2  The Employee further agrees that during his employment he shall
not make, use, or permit to be used any notes, memoranda, drawings,
specifications, programs, data or other materials relating to any matter within
the scope of the business of the Corporation or concerning any of its dealings
or affairs otherwise than for the benefit of the Corporation.

         9.3   The Employee further agrees

              (i)   that he shall not, after the termination of his employment,
    use or permit to be used any such notes, memoranda, drawings,
    specifications, programs, data or other materials, it being agreed that any
    of the foregoing shall be and remain the sole 

                                         -7-

    termination of his employment he shall deliver all of the foregoing, and
    all copies thereof, to the Corporation;

              (ii)  that all files, letters, memoranda, reports, records,
    experimental and other data, sketches, drawings, molds, models, patterns,

    Proprietary Information, whether created by Employee or others, which shall
    come into Employee's custody or possession, shall be and are the exclusive
    property of the Corporation to be used only in the performance of
    Employee's duties for the Corporation;

              (iii) that all such records or copies thereof and all
    tangible property of the Corporation in Employee's custody or possession
    shall be delivered to the Corporation, upon the earlier of a request by the
    Corporation or any termination of  employment; and

              (iv)  that after such delivery, Employee shall not retain any such
    records or copies thereof or any such tangible property, and Employee
    agrees to destroy any Proprietary Information that may be in his possession
    but stored on media (such as computer disks) that themselves are not
    property of the Corporation.

         9.4  Employee agrees that his obligation not to disclose or to use
information and records of the types set forth above (including knowhow), and
his obligation to return records, copies and tangible property set forth in
paragraph (b) above, also extends to such knowhow and other information,
records, copies and tangible property of customers of the 


                                         -8-
<PAGE>

Corporation or suppliers to the Corporation or other third parties who may have
disclosed or entrusted the same to the Corporation or to Employee in the course
of the Corporation's business.

         9.5  Proprietary or Confidential Information of the Corporation
includes any process, document, software, technique or other information
possessed or used by the Corporation and not generally known including, without
limiting the foregoing, trade secrets, processes, techniques, data, software,

projections, budgets, sales records, licenses, prices, costs, and information as
to existing and prospective customers, employees and suppliers.

    10.  Assignment of Inventions.  The Employee agrees as follows:

         10.1 To disclose to the Corporation all inventions, patentable or
unpatentable ideas, and all technical or business innovations developed,
conceived, prepared or created by him solely or in combination with others
during the period of his employment ("Inventions");

         10.2 To assign, and Employee hereby does assign, to the Corporation,

Employee may receive information due to his employment, or (ii) that result from
or are suggested by any work which the Employee may do for the Corporation, or
(iii) that otherwise are made through the use of Corporation time, facilities or
materials;

         10.3 That any such Invention so required to be assigned shall be
considered a work made for hire for the Corporation as such term is defined in
Section 101 of the United States Copyright Act of 1976, as amended;

                                         -9-

assistance during and subsequent to his employment to enable the Corporation to
obtain for itself or its nominees, copyrights, patents or other legal protection

agreement with any previous employer or other party to refrain from using or
disclosing any trade secret or Confidential or Proprietary Information in the

    WHEREAS, the Borrowers and the Bank are parties to an Amended and

    NOW THEREFORE, the parties agree as follows:

    Agreement are true and correct as of the date hereof, as if set forth

                 AMENDED AND RESTATED EMPLOYMENT AGREEMENT


    This Agreement, effective October 1, 1997 amends and restates an 
agreement made effective as of the first day of February 8, 1995, by and 
between Starmet Corporation (formerly NUCLEAR METALS, INC.), a Massachusetts 
corporation with its principal office in Concord, Massachusetts (the 
"Corporation"), and Robert E. Quinn (the "Employee") of Marlborough, 
Massachusetts.

    WHEREAS, the Corporation is engaged in the business of developing and 
marketing metallurgical and other products; and

    WHEREAS, the Employee is employed by the Corporation as its President; and

    WHEREAS, the Employee serves as a Director of the Corporation; and

    WHEREAS, the parties hereto wish to describe the terms under which the 
employment relationship presently existing between Corporation and Employee 
will continue in the future;

    NOW, THEREFORE, in consideration of the foregoing promises and the mutual 
agreements herein contained, the parties hereto agree as follows:

    1.   Employment

    The parties agree to continued employment of the Employee by the 
Corporation during the Term of this Agreement and according to the terms and 
conditions hereof.

    2.   Service by the Employee

    Except as specifically provided herein, the Employee shall continue to 
devote his best efforts and his entire working time during the usual business 
hours of the Corporation, and at such other times as is necessary and 
appropriate to advancing the best interests of the Corporation.  Without 
limiting the generality of the foregoing, such activities shall include 

                                           
<PAGE>

serving as President and a Director of the Corporation.

    3.   Compensation

         3.1  Initial Compensation

         The Employee's minimum annual compensation shall be at the annual rate
    of $200,000 for the Term of this Agreement.

         3.2  Payments

         Such compensation shall be paid to the Employee on a weekly, bi-weekly
    or monthly basis, consistent with the Corporation's normal practice in
    paying compensation to its other executive employees.

         3.3  Increase by the Board of Directors

         The Board of Directors may, from time to time during the Term of this
    Agreement, review compensation and such compensation may be increased (but
    not decreased) from time to time on a basis consistent with the performance
    of Employee and of the Corporation and the salary levels prevailing
    generally for positions of comparable responsibility.

         3.4  Bonuses

         In addition to the foregoing initial compensation, the Corporation may
    pay the Employee a bonus in any year in such amount as may be determined by
    the Board of Directors of the Corporation.

    4.   Employee Benefits

    In addition to the other employee benefits which may be made available to
the Employee from time to time, the Corporation shall provide the following to
the Employee:

                                     2

<PAGE>


         4.1  Benefit Plans

         The Corporation shall include the Employee in all of its benefit
     plans, including pension benefits and major medical, life, accident and 
     health insurance, while he remains an active employee of the Corporation
     during the Term of this Agreement, on the same basis as the coverage 
     provided to other executive employees of the Corporation.

         4.2  Vacations

         The Employee shall be entitled to six (6) weeks of paid vacation each
    fiscal year, earned at the rate of one week for each two months of
    employment hereunder, which vacation shall be taken at such time or times
    as may be agreed upon between the Employee and the Corporation from time to
    time.  The Corporation shall carry forward to succeeding fiscal years any
    accrued vacation unused during the preceding fiscal year.

         4.3  Automobile Allowance

         The Corporation shall provide the Employee with an automobile for his
    use, including use on corporate business.  Any such automobile shall be
    owned and fully maintained by the Corporation, which maintenance shall
    include the cost of gas, oil and automobile insurance.  The Employee shall
    report estimated personal use as required by tax regulations in effect from
    time to time.  In lieu of providing the Employee with an automobile, the
    Corporation may, instead, provide the Employee with an automobile allowance
    in an amount approximately equal to the cost to the Corporation of
    providing an automobile to him.

         4.4  No Reduction of Benefits

                                     3

<PAGE>

         The Corporation shall not eliminate or reduce benefits in effect on
    the date hereof.

    5.   Termination

         5.1  Termination Payments

         The Board of Directors of the Corporation acting on behalf of the
    Corporation and after notice and an opportunity to be heard, may terminate
    the Employee's employment hereunder if a majority of the whole number of
    Directors then in office determine, in good faith, that:

         (a)   the Employee has willfully refused to perform substantially
    all of the services required of him hereunder; or

         (b)   the Employee has been convicted of a crime of moral turpitude.
    In such event, or in the event of voluntary termination by the Employee
    without "good reason," as herein defined, the Employee's right to all
    future payments set forth in subsection 3.1 hereof shall cease.

         5.2  Death

         In the event of the death of the Employee, payments set forth in
    subsection 3.1 shall be made to the executor or administrator or other
    personal representative of the decedent and shall be continued until the
    earliest of one year from the date of death of the Employee or the end of
    the Term of this Agreement.

         5.3  Other Terminations

         In the event of termination by the Corporation other than pursuant to
    subsection 5.1 or of termination by the Employee for good reason, the
    amounts payable pursuant to said subsection 3.1 for the balance of the Term
    of this Agreement shall be due and 

                                     4

<PAGE>


payable upon termination.

         In the event of termination by Employee without good reason, in
    recognition of past services and contributions, the amounts payable
    pursuant to said subsection 3.1 shall be continued for a period of one 
    year from the date of such termination.

         5.4  Definition

         "Good reason", within the meaning of this Agreement, consists of  (a)
    circumstances which, in the reasonable judgment of Employee, constitute a
    material reduction in the Employee's job title, perquisites, duties,
    authority, amenities, benefits or responsibilities; or (b) require the
    Employee regularly to perform services at a location more than twenty-five
    (25) miles distant from the present location of Corporation in Concord,
    Massachusetts, without his consent.

    6.   Payments After Disability

    The Corporation shall pay to the Employee, or to his legal 
representative, the amounts payable pursuant to subsection 3.1 during any 
period of partial or total disability hereunder until the first to occur of 
(a) one year after the date of the Employee's death, or (b) the end of the 
term of this Agreement.  In the event of partial disability, Employee shall 
exert reasonable effort to perform such services thereunder as his disability 
will permit.  The payments made for such disability hereunder shall be 
reduced by the amount of any wage continuation insurance payments payable to 
the Employee or his representative during such period on the basis of any 
disability insurance coverage paid for by the Corporation.  During a period 
of disability the Board of Directors, by written notice given not later than 
February 28 of any year, may terminate this Agreement as of February 28 of 
the third successive year.

                                     5

<PAGE>

    7.   Non-competition

    During the Term of this Agreement and for a period of two (2) years after 
its expiration, or after the termination of Employee's employment with the 
Corporation, whichever occurs later, the Employee shall not compete directly 
or indirectly with the Corporation within the continental United States.

    8.   Term of Agreement

    This Agreement shall continue in force for a term ending February 28, 
2002, unless terminated by either party in accordance herewith.  On February 
28th of each year after 1998, the term hereof automatically shall be extended 
for an additional one-year period,  unless either party gives written notice 
to the other prior to such date of its or his intention not to extend the 
term of this Agreement.  Reference herein to the Term of this Agreement shall 
include the initial period and any period thereafter for which this Agreement 
continues in effect pursuant to the provisions of this Article 8.

    9.   Miscellaneous

         9.1  Binding Nature of Agreement

         This Agreement shall be binding upon the parties hereto, and their
    heirs, legal representatives, successors and assigns.  The Corporation
    shall require any successor to a majority of its business activities to
    assume the obligations of the Corporation herein, however, the Corporation
    shall continue to be liable to Employee for all payments due pursuant to
    this Agreement.

                                     6

<PAGE>

         9.2  No Assignment

         9.3  Notices

         All notices required under this Agreement shall be sufficient if made
    by certified or registered mail, return receipt requested, delivered to the

    office.

         9.4  Amendments and Waivers

    except by written agreement of the parties hereto.  Any waiver of any
    provision of this Agreement, to be enforceable by the non-waiving party,
    must be in writing and signed by the party to be charged therewith; and a

    to the provisions of this section, the Company shall pay the Employee's
    entire cost thereof, including legal fees, whether such litigation is

         appropriate legend evidencing the applicable restrictions under the
         Act.

                                      -1-


<PAGE>


    2.   Events of Default.  An "Event of Default" occurs if:

         (a)  the Company defaults in the payment of interest on this Debenture
    when the same becomes due and payable and the default continues for ten
    (10) days after notice thereof is given to the Company;

         (b)  the Company defaults in the payment of the principal of this
    Debenture when the same becomes due and payable and the default continues
    for ten (10) days after notice thereof;

         (c)  the Company, pursuant to or within the meaning of any Bankruptcy
    Law (A) admits in writing its inability to pay its debts generally as they
    become due, (B) commences a voluntary case or proceeding under any
    Bankruptcy Law with respect to itself, (C) consents to the entry of a
    judgment, decree or order for relief against it in an involuntary case or
    proceeding under any Bankruptcy Law, (D) consents to the appointment of a
    bankruptcy trustee (a "Bankruptcy Trustee") of its or for any part of its
    property, (E) consents to or acquiesces in the institution of bankruptcy or
    insolvency proceedings against it, (F) applies for, consents to or
    acquiesces in the appointment of a Bankruptcy Trustee, (G) makes a general
    assignment for the benefit of its creditors, or (H) takes any corporate
    action for any of the foregoing purposes; or

         (d)  a court of competent jurisdiction enters a judgment, decree or
    order for relief in respect of the Company in an involuntary case or
    proceeding under any Bankruptcy Law which shall (A) approve as properly
    filed a petition seeking reorganization, arrangement, adjustment or
    composition in respect of the Company, (B) appoint a Bankruptcy Trustee of
    the Company or for any part of its property, or (C) order the winding-up or
    liquidation of its affairs; and such judgment, decree or order shall remain
    unstayed and in effect for a period of 60 consecutive days; or (D) any
    bankruptcy or insolvency petition or application is filed, or any
    bankruptcy or insolvency proceeding is commenced against the Company and
    such petition, application or proceeding is not dismissed within 60 days.

    The term "Bankruptcy Law" means Title 11, U.S. Code or any similar federal
or state law for the relief of debtors.  

    3.   Remedies.  If an Event of Default (other than an Event of Default
specified in Section 2(c) or 2(d) in respect of the Company) occurs and is
continuing, the Holder may, subject to Section 4 hereof, by notice of the
Company, declare all unpaid principal and accrued interest to the date of
acceleration on the Debenture then outstanding (if not then due and payable) to
be due and payable and, upon any such declaration, the same shall become and be
immediately due and payable.  If an Event of Default specified in Section 2(c)
or 2(d) in respect of the Company occurs, all unpaid principal and accrued
interest on the Debenture then outstanding shall ipso facto become and be
immediately due and payable without any declaration or other act on the part of
any Holder.  The Holder by notice to the Company may rescind an 


                                      -2-


<PAGE>


acceleration and its consequences if (i) all existing Events of Default, other
than the non-payment of the principal of the Debenture which has become due
solely by such declaration of acceleration, have been cured or waived, (ii) to
the extent the payment of such interest is lawful, interest on overdue
installments of interest and overdue principal, which has become due otherwise
than by such declaration of acceleration, has been paid, and (iii) the
rescission would not conflict with any judgment or decree of a court of
competent jurisdiction.

    4.   Subordination.  The Company covenants and agrees, for itself and its
successor and assigns, and each Holder hereof, for itself and for any subsequent
holder of this Debenture, by its acceptance hereof, covenants and agrees that
the indebtedness evidenced hereby is hereby expressly subordinated, to the
extent and in the manner hereinafter set forth, in right of payment to the prior
payment for satisfaction in full in cash of all Senior Indebtedness, as
hereinafter defined.

    Until all Senior Indebtedness shall have been performed or paid in full in
cash, (a) the Company shall not, directly or indirectly, and the holder of this
Debenture shall not be permitted to receive any payment on account of this
Debenture and the holder of this Debenture shall not demand or accept from the
Company or any person any such payment or otherwise discharge any part of the
obligations of the Company hereunder and such holder shall not take any action
prejudicial to, or inconsistent with, the priority position of the Senior
Indebtedness over the holder hereof, including, without limitation, declaring
all unpaid principal and accrued interest under this Debenture due and payable,
commencing any action or proceeding against the Company to enforce to collect
this Debenture, or any portion hereof or commencing or joining any "Proceeding"
(as defined below) against the Company, and (b) the holder of this Debenture
shall have no right of subrogation to receive payments or distributions of
assets of the Company applicable to the Senior Indebtedness.  Notwithstanding
the foregoing, so long as no default exists under any agreement or instrument
evidencing any of the Senior Indebtedness, interest and principal may be paid on
this Debenture in accordance with the terms hereof.

    At any meeting of creditors of the Company or in the event of any
proceeding ("Proceeding"), voluntary or involuntary, for the distribution,
division or application of all or part of the assets of the Company, whether
such proceeding be for the liquidation, dissolution or winding up of the Company
or its business, or proceeding for relief under any bankruptcy, reorganization
or insolvency law or any other law relating to relief of debtors, readjustment
of indebtedness, reorganization, arrangement, composition or extension or
otherwise, the holder of the Senior Indebtedness is hereby irrevocably
authorized by the holder of this Debenture at any such meeting or in any such
proceeding:  (a) to prove any claim (by the filing of proof(s) of claim(s) or
otherwise) on account of this Debenture either in its own name or in the name of
the holder hereof; (b) to collect any assets of the Company distributed, divided
or applied by way of dividend or payment, or any securities issued, on account
of this Debenture and apply the same to the Senior Indebtedness; (c) to vote
claims on account of this Debenture to accept or reject any plan for
liquidation, reorganization, arrangement, composition or extension; and (d) to
take generally any action in connection with any such meeting or proceeding
which the holder of this Debenture might otherwise take.


                                      -3-


<PAGE>


    Upon the occurrence of any default under any agreement or instrument
evidencing any of the Senior Indebtedness, should any payment be received by the
holder of this Debenture, such payment shall be delivered forthwith to the
holder of the Senior Indebtedness for application to the Senior Indebtedness. 
The holder of the Senior Indebtedness is irrevocably authorized to supply any
required endorsement or assignment.  Until so delivered, any such payment shall
be held by the holder of this Debenture in trust for the holder of the Senior
Indebtedness and shall not be commingled with other funds or property of the
holder of this Debenture.

    Without the necessity of any reservation of rights against or any notice to
or further assent by the holder of this Debenture, any demand for payment of any
Senior Indebtedness made by the holder of the Senior Indebtedness may be
rescinded in whole or in part by such holder, the holder of the Senior
Indebtedness may exercise or refrain from exercising any rights and remedies
against the Company and others, the Senior Indebtedness or any collateral
security or guaranty therefor or right of offset with respect thereto, may be
executed, or released by the holder of Senior Indebtedness, and any agreement or
instrument evidencing, securing or otherwise relating to Senior Indebtedness may
be amended or modified, all without impairing, abridging, releasing or affecting
the subordination provided for herein.  The holder of this Debenture waives any
and all notice of the creation or modification of any Senior Indebtedness and
notice of or proof of reliance by the holder of the Senior Indebtedness upon the
subordination provided for herein.

    For purposes of this Debenture, "Senior Indebtedness" shall include any and
all indebtedness, liabilities, duties, undertakings, warranties, covenants and
agreements (including those of payment or performance) of the Company or any of
its wholly-owned subsidiaries to State Street Bank and Trust Company and its
respective successors or assigns (the "Lender"), of every kind, nature and
description and arising pursuant to the terms of the Forbearance and Amendment
Agreement ("Amendment Agreement") dated as of January 11, 1996 between the
Company, its wholly-owned subsidiary, Carolina Metals, Inc. ("CMI"), and the
Lender, as may be amended, modified, supplemented and/or restated from time to
time, the Loan Documents and Bond Documents, as defined in the Amendment
Agreement, as such Documents may be amended, modified, supplemented and/or
restated from time to time, or otherwise, whether or not the same are: now
existing or hereafter arising; imposed by agreement or by operation of law; due
or not due; absolute or contingent (including any reimbursement obligations
relating to any letter of credit issued for the account of the Company or CMI);
liquidated or unliquidated; voluntary or involuntary, evidenced by a writing;
presently contemplated by the parties; direct or indirect; liabilities or
undertakings of the Company or any of its subsidiaries as surety, guarantor or
endorser with respect to obligations of one or more other parties specifically
described as secured or unsecured, hereafter acquired by the Lender or any of
them by assignment, other transfer or operation of law.  Senior Indebtedness
also shall include any refinancings thereof or replacement financing therefor.

    5.   Interest Limitation.  If a law, which applies to this Debenture and
which sets maximum loan charges, is finally interpreted so that the interest or
other loan charges collected or to be collected in connection with this
Debenture exceed the permitted limits, then:  (i) any 


                                      -4-


<PAGE>


such loan charge shall be reduced by the amount necessary to reduce the charge
to the permitted limit; and (ii) any sums already collected from the Company
which exceeded permitted limits will be refunded to the Company.  The Holder may
choose to make this refund by reducing the principal owed under this Debenture
or by making a direct payment to the Company.

    6.   Consent to Jurisdiction.  The Holder hereby irrevocably agrees that
any legal action or proceedings with respect to this Debenture against the
Company may be brought only in the courts of the United States of America or The
Commonwealth of Massachusetts. By acceptance of this Debenture, the Holder
hereby (i) accepts the exclusive jurisdiction of the aforesaid courts; (ii)
irrevocably agrees to be bound by any judgment of any such court with respect to
this Debenture; and (iii) irrevocably waives, to the fullest extent permitted by
law, any objection which it may now or hereafter have to the laying of venue of
any suit, action or proceedings with respect to this Debenture brought in any
court of the United States of America or The Commonwealth of Massachusetts, and
further irrevocably waives any claim that any such suit, action or proceeding
brought in any such court has been brought in an inconvenient forum.

    7.   Miscellaneous. 
    
         (a)  THIS DEBENTURE SHALL BE GOVERNED BY THE LAWS OF THE COMMONWEALTH
    OF MASSACHUSETTS WITHOUT REFERENCE TO CONFLICTS OF LAWS RULES OR
    PRINCIPLES.

         (b)  The Company and all endorsers of this Debenture hereby waive
    presentment, demand, protest or notice of any kind in connection with the
    delivery, acceptance, performance or enforcement of this Debenture.

         (c)  No provision thereof shall alter or impair the obligation of the
    Company which is absolute and unconditional, to pay the principal and
    interest on this Debenture as herein prescribed.

                        10% Convertible Subordinated Debenture
                                Due December 31, 1999


($500,000.00)                                    December 23, 1997



    Starmet Corporation., a Massachusetts corporation (the "Company"), for
value received, hereby promises to pay to WIAF Investors Co. or registered
assigns (the "Holder"), the principal sum of Five Hundred Thousand Dollars
($500,000.00) on December 31, 1999 (the "Maturity Date") with interest from the
date hereof (computed on the basis of a 365-day year) at the rate per annum of
ten percent (10%) until paid in full.  The Company will pay interest in arrears
semi-annually on the last day of each June and of each December (each an
"Interest Payment Date") to the Holder of record.  Interest will accrue from the
most recent date to which interest has been paid or if no interest has been
paid, from the date of issuance of this debenture. 

    1.   General.  This  debenture (the "Debenture") is transferable only by
surrender thereof at the principal office of the Company located at 2229 Main
Street, Concord, Massachusetts  01742, duly endorsed by, or accompanied by a
written instrument of transfer duly executed by, the registered Holder of this
Debenture or his attorney duly authorized in writing and a completed "investor
questionnaire" duly executed by the transferee reasonably satisfactory in form
and substance to the Company.

    2.   Events of Default.  An "Event of Default" occurs if:

         (a)  the Company defaults in the payment of interest on this Debenture
    when the same becomes due and payable and the default continues for ten
    (10) days after notice thereof is given to the Company;

                                         -1-
<PAGE>

         (b)  the Company defaults in the payment of the principal of this
    Debenture when the same becomes due and payable and the default continues
    for ten (10) days after notice thereof;

         (c)  the Company, pursuant to or within the meaning of any Bankruptcy
    Law (A) admits in writing its inability to pay its debts generally as they
    become due, (B) commences a voluntary case or proceeding under any
    Bankruptcy Law with respect to itself, (C) consents to the entry of a
    judgment, decree or order for relief against it in an involuntary case or
    proceeding under any Bankruptcy Law, (D) consents to the appointment of a
    bankruptcy trustee (a "Bankruptcy Trustee") of its or for any part of its
    property, (E) consents to or acquiesces in the institution of bankruptcy or
    insolvency proceedings against it, (F) applies for, consents to or
    acquiesces in the appointment of a Bankruptcy Trustee, (G) makes a general
    assignment for the benefit of its creditors, or (H) takes any corporate
    action for any of the foregoing purposes; or

         (d)  a court of competent jurisdiction enters a judgment, decree or
    order for relief in respect of the Company in an involuntary case or
    proceeding under any Bankruptcy Law which shall (A) approve as properly
    filed a petition seeking reorganization, arrangement, adjustment or
    composition in respect of the Company, (B) appoint a Bankruptcy Trustee of
    the Company or for any part of its property, or (C) order the winding-up or
    liquidation of its affairs; and such judgment, decree or order shall remain
    unstayed and in effect for a period of 60 consecutive days; or (D) any
    bankruptcy or insolvency petition or application is filed, or any
    bankruptcy or insolvency proceeding is commenced against the Company and
    such petition, application or proceeding is not dismissed within 60 days.

    The term "Bankruptcy Law" means Title 11, U.S. Code or any similar federal
or state law for the relief of debtors.  

    3.   Remedies.  If an Event of Default (other than an Event of Default
specified in Section 2(c) or 2(d) in respect of the Company) occurs and is
continuing, the Holder may, subject to Section 4 hereof, by notice of the
Company, declare all unpaid principal and accrued interest to the date of
acceleration on the Debenture then outstanding (if not then due and payable) to
be due and payable and, upon any such declaration, the same shall become and be
immediately due and payable.  If an Event of Default specified in Section 2(c)
or 2(d) in respect of the Company occurs, all unpaid principal and accrued
interest on the Debenture then outstanding shall ipso facto become and be
immediately due and payable without any declaration or other act on the part of
any Holder.  The Holder by notice to the Company may rescind an acceleration and
its consequences if (i) all existing Events of Default, other than the
non-payment of the principal of the Debenture which has become due solely by
such declaration of acceleration, have been cured or waived, (ii) to the extent
the payment of such interest is lawful, interest on overdue installments of
interest and overdue principal, which has become due otherwise than by such
declaration of acceleration, has been paid, and (iii) the rescission would not
conflict with any judgment or decree of a court of competent jurisdiction.

                                         -2-

    4.   Subordination.  The Company covenants and agrees, for itself and its
successor and assigns, and each Holder hereof, for itself and for any subsequent
holder of this Debenture, by its acceptance hereof, covenants and agrees that
the indebtedness evidenced hereby is hereby expressly subordinated, to the
extent and in the manner hereinafter set forth, in right of payment to the prior
payment for satisfaction in full in cash of all Senior Indebtedness, as
hereinafter defined.

    Until all Senior Indebtedness shall have been performed or paid in full in
cash, (a) the Company shall not, directly or indirectly, and the holder of this
Debenture shall not be permitted to receive any payment on account of this
Debenture and the holder of this Debenture shall not demand or accept from the
Company or any person any such payment or otherwise discharge any part of the
obligations of the Company hereunder and such holder shall not take any action
prejudicial to, or inconsistent with, the priority position of the Senior
Indebtedness over the holder hereof, including, without limitation, declaring
all unpaid principal and accrued interest under this Debenture due and payable,
commencing any action or proceeding against the Company to enforce to collect
this Debenture, or any portion hereof or commencing or joining any "Proceeding"
(as defined below) against the Company, and (b) the holder of this Debenture
shall have no right of subrogation to receive payments or distributions of
assets of the Company applicable to the Senior Indebtedness.  Notwithstanding
the foregoing, so long as no default exists under any agreement or instrument
evidencing any of the Senior Indebtedness, interest and principal may be paid on
this Debenture in accordance with the terms hereof.

    At any meeting of creditors of the Company or in the event of any
proceeding ("Proceeding"), voluntary or involuntary, for the distribution,
division or application of all or part of the assets of the Company, whether
such proceeding be for the liquidation, dissolution or winding up of the Company
or its business, or proceeding for relief under any bankruptcy, reorganization
or insolvency law or any other law relating to relief of debtors, readjustment
of indebtedness, reorganization, arrangement, composition or extension or
otherwise, the holder of the Senior Indebtedness is hereby irrevocably
authorized by the holder of this Debenture at any such meeting or in any such
proceeding:  (a) to prove any claim (by the filing of proof(s) of claim(s) or
otherwise) on account of this Debenture either in its own name or in the name of
the holder hereof; (b) to collect any assets of the Company distributed, divided
or applied by way of dividend or payment, or any securities issued, on account
of this Debenture and apply the same to the Senior Indebtedness; (c) to vote
claims on account of this Debenture to accept or reject any plan for
liquidation, reorganization, arrangement, composition or extension; and (d) to
take generally any action in connection with any such meeting or proceeding
which the holder of this Debenture might otherwise take.

    Upon the occurrence of any default under any agreement or instrument
evidencing any of the Senior Indebtedness, should any payment be received by the
holder of this Debenture, such payment shall be delivered forthwith to the
holder of the Senior Indebtedness for application to the Senior Indebtedness. 
The holder of the Senior Indebtedness is irrevocably authorized to supply any
required endorsement or assignment.  Until so delivered, any such payment shall
be 

                                         -3-
<PAGE>

held by the holder of this Debenture in trust for the holder of the Senior
Indebtedness and shall not be commingled with other funds or property of the
holder of this Debenture.

    Without the necessity of any reservation of rights against or any notice to
or further assent by the holder of this Debenture, any demand for payment of any
Senior Indebtedness made by the holder of the Senior Indebtedness may be
rescinded in whole or in part by such holder, the holder of the Senior
Indebtedness may exercise or refrain from exercising any rights and remedies
against the Company and others, the Senior Indebtedness or any collateral
security or guaranty therefor or right of offset with respect thereto, may be
executed, or released by the holder of Senior Indebtedness, and any agreement or
instrument evidencing, securing or otherwise relating to Senior Indebtedness may
be amended or modified, all without impairing, abridging, releasing or affecting
the subordination provided for herein.  The holder of this Debenture waives any
and all notice of the creation or modification of any Senior Indebtedness and
notice of or proof of reliance by the holder of the Senior Indebtedness upon the
subordination provided for herein.

    For purposes of this Debenture, "Senior Indebtedness" shall include any and
all indebtedness, liabilities, duties, undertakings, warranties, covenants and
agreements (including those of payment or performance) of the Company or any of
its wholly-owned subsidiaries to State Street Bank and Trust Company and its
respective successors or assigns (the "Lender"), of every kind, nature and
description including, without limiting the foregoing, that arising pursuant to
the terms of the Forbearance and Amendment Agreement ("Amendment Agreement")
dated as of January 11, 1996 between the Company, its wholly-owned subsidiary,
Carolina Metals, Inc. ("CMI," now Starmet CMI, Inc.), and the Lender, as it has
been and may be amended, modified, supplemented and/or restated from time to
time, the Loan Documents and Bond Documents, as defined in the Amendment
Agreement, as such Documents may be amended, modified, supplemented and/or
restated from time to time, or otherwise, whether or not the same are: now
existing or hereafter arising; imposed by agreement or by operation of law; due
or not due; absolute or contingent (including any reimbursement obligations
relating to any letter of credit issued for the account of the Company or CMI);
liquidated or unliquidated; voluntary or involuntary, evidenced by a writing;
presently contemplated by the parties; direct or indirect; liabilities or
undertakings of the Company or any of its subsidiaries as surety, guarantor or
endorser with respect to obligations of one or more other parties specifically
described as secured or unsecured, hereafter acquired by the Lender or any of
them by assignment, other transfer or operation of law.  Senior Indebtedness
also shall include any refinancings thereof or replacement financing therefor.

    5.   Conversion Right.  Subject to and upon compliance with the provisions
of this Debenture, the Holder of this Debenture has the right at any time, at
his option, to convert the principal of this Debenture into such number (the
"Debenture Shares") of fully paid and non-assessable shares of common stock,
$.01 par value (the "Common Stock") of the Company as shall equal the principal
amount of this Debenture divided by the Conversion Price (as hereinafter
defined).  A conversion shall only occur upon surrender of this Debenture to the
Company  at its principal place of business, duly endorsed by, or accompanied by
instruments of transfer (in 

                                         -4-
<PAGE>

form reasonably satisfactory to the Company) duly executed by the Holder or his
attorney duly authorized in writing, together with a conversion notice and
transfer tax stamps or funds therefor, if required. If this Debenture is
surrendered for conversion  prior to an Interest Payment Date, the Holder shall
be entitled to receive interest accrued prior to conversion on the relevant
Interest Payment Date.

    6.   Manner of Exercising Conversion Rights.  In order to exercise the
conversion privilege, the Holder shall surrender this Debenture to the Company
at any time during usual business hours at its offices in Concord,
Massachusetts, and shall give written notice to the Company at such office that
the Holder elects to convert this Debenture.  Such notice shall also state the
name or names (with address or addresses) in which the certificate or
certificates for shares of Common Stock which shall be deliverable upon such
conversion shall be registered.  As promptly as practicable after the receipt of
such notice and the surrender of this Debenture as aforesaid, the Company shall
then cancel this Debenture and shall issue and deliver at such office to such
Holder, or on his written order, a certificate or certificates for the number of
full shares of Common Stock deliverable on such conversion of this Debenture in
accordance with the provisions of this Debenture and cash as provided in the
following Section, in respect of any fraction of a share of Common Stock
otherwise deliverable upon such conversion.  Such conversion shall be deemed to
have been effected immediately prior to the close of business on the date
(herein called the "Date of Conversion") on which such notice shall have been
received by the Company and this Debenture shall have been surrendered as
aforesaid, and the person or persons in whose name or names any certificate or
certificates for shares of Common Stock shall be issuable upon such conversion
shall be deemed to have become on the Date of Conversion the holder or holders
of record of the shares represented thereby; provided, however, that any such
surrender on any date when the stock transfer books of the Company shall be
closed shall be deemed effected at the opening of business on the next
succeeding day on which such stock transfer books are open, and the person or
persons in whose name or names the certificate or certificates for such shares,
are to be issued shall be deemed to have become the record holder or holders
thereof for all purposes as of such date.

    7.   No Fractional Shares.  No fractions of shares of Common Stock or scrip
representing fractions of shares of Common Stock shall be issued upon conversion
of this Debenture.  If more than one Debenture shall be surrendered for
conversion at one time by the same Holder, the number of full shares of Common
Stock which shall be deliverable upon conversion thereof shall be computed on
the basis of the aggregate principal amount of the Debentures so surrendered. 
If any fraction of a share of Common Stock would, except for the provisions of
this Section, be deliverable on the conversion of this Debenture or Debentures
(or specified portions thereof), the Company shall make payment in lieu thereof
in an amount of cash equal to the value of such fraction multiplied by the
Conversion Price.

    8.   Conversion Price Adjustments.  (a) For purposes of this Debenture:

                                         -5-
<PAGE>

    "Additional Shares of Common Stock" shall mean all shares of Common Stock
issued (or, pursuant to this Debenture, deemed to be issued) by the Company,
other than shares of Common Stock issued or issuable:

         (i)  upon conversion of the Debentures; or

         (ii) in lieu of interest on the Debentures.

    "Conversion Price" shall mean the price at which shares of the Common Stock
shall be deliverable upon conversion of this Debenture as adjusted from time to
time as herein provided.  The initial Conversion Price is $21.50.  The
Conversion Price for this Debenture shall be subject to adjustment as herein
provided.

    "Recapitalization Events" shall mean stock splits, stock dividends,
recapitalizations, reclassifications and similar events.

         A.   Adjustment for Stock Splits and Combinations.  If the Company at
    any time or from time to time after the Issuance Date effects a subdivision
    of the outstanding Common Stock, the Conversion Price then in effect
    immediately before that subdivision shall be proportionately decreased, and
    conversely, if the Company at any time or from time to time after the
    Issuance Date combines the outstanding shares of Common Stock, the
    Conversion Price then in effect immediately before the combination shall be
    proportionately increased.  Any adjustment under this subsection shall
    become effective at the close of business on the date the subdivision or
    combination becomes effective.

         B.   Adjustment for Certain Dividends and Distributions.  In the event
    the Company at any time, or from time to time after the Issuance Date
    makes, or fixes a record date for the determination of holders of Common
    Stock entitled to receive, a dividend or other distribution payable in
    Additional Shares of Common Stock, then and in each such event the
    Conversion Price then in effect shall be decreased as of the time of such
    issuance or, in the event such a record date is fixed, as of the close of
    business on such record date, by multiplying the Conversion Price then in
    effect by a fraction (a) the numerator of which is the total number of
    shares of Common Stock issued and outstanding immediately prior to the time
    of such issuance or the close of business on such record date, and (b) the
    denominator of which shall be the total number of shares of Common Stock
    issued and outstanding immediately prior to the time of such issuance or
    the close of business on such record date plus the number of shares of
    Common Stock issuable in payment of such dividend or distribution;
    provided, however, that if such record date is fixed and such dividend is
    not fully paid or if such distribution is not fully made on the date fixed
    thereof, the Conversion Price shall be recomputed accordingly as of the
    close of business on such record date and thereafter the Conversion Price
    shall be adjusted pursuant to this Section 8B as of the time of actual
    payment of such dividends or distributions.

                                         -6-
<PAGE>

         C.   Adjustments for Other Dividends and Distributions.  In the event
    the Company at any time or from time to time after the Issuance Date makes,
    or fixes a record date for the determination of holders of Common Stock
    entitled to receive a dividend or other distribution payable in securities
    of the Company other than shares of Common Stock, then in each such event
    provision shall be made so that the Holder shall receive upon conversion of
    this Debenture, in addition to the number of shares of Common Stock
    receivable thereupon, the amount of securities of the Company which they
    would have received had this Debenture been converted into Common Stock on
    the date of such event and had the Holder thereafter, during the period
    from the date of such event to and including the date of conversion,
    retained such securities receivable by them as aforesaid during such
    period, subject to all other adjustments called for during such period
    under this Section 8 with respect to the rights of the holders of this
    Debenture.

         D.   Adjustment for Reclassification, Exchange and Substitution.  If
    the Common Stock issuable upon the conversion of this Debenture is changed
    into the same or a different number of shares of any class or classes of
    stock, whether by recapitalization, reclassification or otherwise (other
    than a subdivision or combination of shares of stock dividend or a
    reorganization, provided for elsewhere in this Section 8, then and in any
    such event the Holder of this Debenture shall have the right thereafter to
    convert such stock into the kind and amount of stock and other securities
    and property receivable upon such reorganization, reclassification or other
    change, by holders of the number of shares of Common Stock into which such
    a Debenture  might have been converted immediately prior to such
    reorganization, reclassification or change, all subject to further
    adjustments provided herein.

         E.   Reclassification, Reorganization, Etc.  If any of the following
    shall occur, namely: (a) any reclassification or change of outstanding
    shares of Common Stock issuable upon conversion of this Debenture (other
    than a change in par value, or from par value to no par value, or from par
    value to no par value, or from no par value to par value, or as a result of
    a subdivision or combination), (b) any consolidation or merger to which the
    Company is a party other than a merger in which the Company is the
    continuing corporation and which does not result in any reclassification
    of, or change (other than a change in name, or par value, or from par value
    to no par value, or from no par value to par value, or as a result of a
    subdivision or combination) in, outstanding shares of Common Stock or (c)
    any sale or conveyance of all or substantially all of the property or
    business of the Company as an entirety, then the Company, or such successor
    or purchasing corporation, as the case may be, shall, as a condition
    precedent to such reclassification, change, consolidation, merger, sale or
    conveyance, execute and  deliver a certificate providing that the Holder of
    this Debenture then outstanding shall have the right to convert such
    Debenture into the kind and amount of shares of stock and other securities
    and property (including cash) receivable upon such reclassification,
    change, consolidation, merger, sale or conveyance by a holder of the number
    of shares of Common Stock deliverable upon conversion of this Debenture
    immediately prior to such reclassification, change, consolidation, merger,
    sale or conveyance.  If, in the case of any 

                                         -7-
<PAGE>

    such consolidation, merger, sale or conveyance, the stock or other
    securities and property (including cash) receivable thereupon by a holder
    of Common Stock includes shares of stock or other securities and property
    of a corporation other than the successor or purchasing corporation, as the
    case may be, in such consolidation, merger, sale or conveyance, then such
    certificate shall also be executed by such other corporation and shall
    contain such additional provision to protect the interests of the Holders
    of the Debentures as the Board of Directors of the Company shall reasonably
    consider necessary by reason of the foregoing.  The provisions of this
    Section shall similarly apply to successive consolidation, mergers, sales
    or conveyances.

    9.   Interest Limitation.  If a law, which applies to this Debenture and
which sets maximum loan charges, is finally interpreted so that the interest or
other loan charges collected or to be collected in connection with this
Debenture exceed the permitted limits, then:  (i) any such loan charge shall be
reduced by the amount necessary to reduce the charge to the permitted limit; and
(ii) any sums already collected from the Company which exceeded permitted limits
will be refunded to the Company.  The Holder may choose to make this refund by
reducing the principal owed under this Debenture or by making a direct payment
to the Company.

    10.  Consent to Jurisdiction.  The Holder hereby irrevocably agrees that
any legal action or proceedings with respect to this Debenture against the
Company may be brought only in the courts of the United States of America or The
Commonwealth of Massachusetts. By acceptance of this Debenture, the Holder
hereby (i) accepts the exclusive jurisdiction of the aforesaid courts; (ii)
irrevocably agrees to be bound by any judgment of any such court with respect to
this Debenture; and (iii) irrevocably waives, to the fullest extent permitted by
law, any objection which it may now or hereafter have to the laying of venue of
any suit, action or proceedings with respect to this Debenture brought in any
court of the United States of America or The Commonwealth of Massachusetts, and
further irrevocably waives any claim that any such suit, action or proceeding
brought in any such court has been brought in an inconvenient forum.

    11.  Miscellaneous. 
    
         (a)  THIS DEBENTURE SHALL BE GOVERNED BY THE LAWS OF THE COMMONWEALTH
    OF MASSACHUSETTS WITHOUT REFERENCE TO CONFLICT OF LAWS RULES OR PRINCIPLES.

         (b)  The Company and all endorsers of this Debenture hereby waive
    presentment, demand, protest or notice of any kind in connection with the
    delivery, acceptance, performance or enforcement of this Debenture.

                                         -8-
<PAGE>

    (c)  No provision thereof shall alter or impair the obligation of the
    Company which is absolute and unconditional, to pay the principal and 
    interest on this Debenture as herein prescribed.

    WHEREAS, the Borrowers and the Bank are parties to an Amended and Restated
Credit Agreement dated as of October 1, 1997 (the "Credit Agreement"); and

    WHEREAS, the parties have agreed to certain modifications;

    NOW THEREFORE, the parties agree as follows:

    1.   Section 1.01.  The Credit.  Section 1.01 of the Credit Agreement is
hereby amended by deleting the reference to "$8,050,000" in the third line and
"$8,050,000" in the last line and replacing both references with "$9,550,000".  

    2.   Section 1.02(a).  Amount.  Section 1.02(a) of the Credit Agreement is
hereby amended by deleting the proviso at the end of Section 1.02(a) and
substituting therefor the following:

    "provided that the aggregate of all Advances outstanding at any time less
    the maximum aggregate liability of the Borrowers under any outstanding
    letters of credit issued prior to the date hereof or pursuant to this
    Credit Agreement shall not exceed (i) $9,550,000 through June 30, 1998,
    (ii) $8,050,000 from July 1, 1998 through September 30, 1998, and (iii)
    $6,550,000 on October 1, 1998 and thereafter (such amount as in effect from
    time to time may be referred to as the "Maximum Credit")."

    3.   Section 1.02(b).  Revolving Credit Agreement.  Section 1.02(b) of the
Credit Agreement is hereby amended by adding the following at the end: 

<PAGE>


    "As provided in Section 1.02(a), the Maximum Credit shall reduce from
    $9,550,000 to $8,050,000 on July 1, 1998 and from $8,050,000 to $6,550,000
    on October 1, 1998, and any amount in excess of the Maximum Credit as so
    reduced shall be paid on or before such dates".

    4.   Section 1.02(c).  The Revolving Credit Note.  Section 1.02(c) of the
Credit Agreement is hereby amended by  deleting the first sentence in Section
1.02(c) its entirety and substituting therefor the following:

    "Amounts owed to Bank with respect to Advances made by Bank shall be
    evidenced by Bank's books and records and may, at the request of the Bank,
    be further evidenced by one or more revolving credit notes (collectively,
    the "Revolving Credit Note").  As of the date of this Second Amendment, the
    Advances are evidenced by an Amended and Restated Revolving Credit Note
    dated as of March 31, 1995 (as amended and restated October 1, 1997) in the
    principal amount of $6,550,000 (the "Original Note") and a Second
    Additional Revolving Credit Note dated as of the date of this Second
    Amendment in the principal amount of $3,000,000 (the "Additional Note"). 
    All Advances shall be deemed made pursuant to the Original Note up to the
    maximum principal amount thereof and thereafter pursuant to the Additional
    Note.  Any repayments of principal shall be applied first to the Additional
    Note, then to the Original Note".


    5.   Section 4.20.  Debt-Tangible Capital Base.  The first sentence is
amended in its entirety to read as follows:

    "The ratio of Debt to Tangible Capital Base of the Borrowers on a
    consolidated basis shall not exceed 0.60 to 1.00."

    6.   Section 4.21.  Tangible Capital Base shall be amended in its entirety
to read as follows:

    "The Tangible Capital Base of the Borrowers on a consolidated basis shall
    be not less than $26,750,000 as of January 10, 1998, and $26,750,000 plus
    an increase equal to the aggregate of 75% of the Borrowers' Net Income for
    each fiscal quarter after December 31, 1997 in which the Borrowers have
    positive net income (with no reduction for fiscal quarters in which the
    Borrowers incur a loss) determined as of the end of each fiscal quarter
    commencing March 31, 1998."

    7.   Section 4.22.  Net Income shall be amended in its entirety as follows:

    "The Net Income of the Borrowers for the periods set forth below shall be
    not less than the amounts set forth opposite such periods:

    and thereafter                     $750,000"

    "Net Income" shall mean the consolidated net income of the Borrowers before
interest and taxes, plus (a) to the extent deducted in calculating Net Income
prior to March 31, 1998, any reserves established as a result of the litigation
commenced by Brush Wellman, and (b) costs associated with the execution of the
Second Amendment including the fees set forth in paragraph 11 of the Second
Amendment."
    
    8.   Section 4.23.  Capital Expenditures.  The amount "$1,000,000" is
amended to read "$2,000,000".  The Bank waives compliance with this covenant for

              amounts                  date
              -------                  ----
              $4,750,000               March 15, 1997
              $3,000,000               July 15, 1997


                                         -3-

    12.  Effectiveness.  This Second Amendment to Credit Agreement shall become
effective upon (a) execution of this Second Amendment by the Borrowers and the
Bank, (b) execution by the Borrowers of the Additional Note substantially in the
form of Exhibit A attached hereto, (c) receipt by the Bank of evidence
satisfactory to the Bank that the Borrowers are authorized to execute this First

    and warranties of the Borrowers set forth in Article II of the Credit
    Agreement are true and correct as of the date hereof, as if set forth
    herein in full.

         (b)       There is no Event of Default, and no condition which, with
    the passage of time or giving of notice or both, would constitute an Event
    of Default under the Credit Agreement except as amended or waived in this
    Second Amendment.

         (c)       Except as set forth above and in the First Amendment dated
    as of December 19, 1997, the Credit Agreement remains in full force and
    effect.

PRESIDENT'S LETTER
Dear Stockholder:

    Fiscal 1997 was a good year for Starmet Corporation (formerly Nuclear 
Metals, Inc.). While revenues were essentially level with Fiscal 1996, net 
income of $1.5 million in Fiscal 1997 compared favorably with a $3.1 million 
loss in the prior year.  In November 1997 Starmet CMI, our wholly owned 
subsidiary, announced new orders and options valued at $5.5 million for work 
to be performed in Fiscal 1998 with revenues beginning in the second quarter. 
 This unique facility for uranium conversion had been without a major 
customer since the fourth quarter of Fiscal 1996, resulting in negative cash 
flow during this period.  The new orders to restart our uranium conversion 
process and further expand our Department of Energy licensed DUCRETE-TM- 
stabilization technology should result in Starmet CMI returning to revenue 
growth.

FINANCIAL HIGHLIGHTS

    Revenues in Fiscal 1997 of $28.1 million compared to $28.7 million in 
Fiscal 1996.  Net income of $1.5 million compared favorably to a loss of $3.1 
million the prior year.  Year-end backlog increased to $27.7 million from 
$23.3 million the prior year.  Capital expenditures of $1.8 million compared 
to $1.4 million the prior year.  Research and development spending of $1.3 
million compared to $0.9 million the prior year.

    The Fiscal 1997 year-end balance sheet showed an increase in the current 
ratio (current assets / current liabilities) to 2.5 : 1 from 1.99 : 1 in the 
prior year. Our quick ratio (current assets less inventory / current 
liabilities) increased to 0.9 : 1 from 0.7 : 1 the prior year.  Year-end cash 
and cash equivalents decreased 

                                       1


<PAGE>

to $0.27 million from $1.30 million the prior year.  Long term debt increased 
to $3.4 million from $1.9 million in the prior year.  State Street Bank & 
Trust Company, our commercial bank, increased the Company's line of credit to 
$6.0 million in December 1997.

[CHART]

NAME CHANGE AND NEW SUBSIDIARIES

    In late September 1997 shareholders voted to change the name of the Company
to Starmet Corporation and to create several  wholly owned subsidiaries.  This
name change and new organizational structure should help us grow our business
more rapidly by providing greater flexibility to create strategic alliances and
otherwise finance the growth of our diverse technologies and markets.

STARMET CMI & NMI

    The Company's uranium processing technology, used primarily for shielding 
applications and feed rod for advanced laser enrichment, is the foundation of 
the new Starmet CMI and NMI subsidiaries.  Restart of our uranium 
hexafluoride (UF(6)) conversion process beginning in the second quarter of 
Fiscal 1998 will dramatically improve plant utilization and is expected to 
provide the basis for profitability for Starmet CMI.  Growing customer 
acceptance of DUCRETE-TM- as a commercially viable stabi-

                                       2
<PAGE>

lization technology with beneficial reuse of the depleted uranium as a 
shielding material for high level wastes should result over the longer term 
in significant new business from the Department of Energy and commercial 
power companies.

STARMET POWDERS

    The PREP-TM- powder technology for producing spherical powder of a 
uniform size which is free of ceramic contamination is the cornerstone of 
this subsidiary.  There are several niche markets for high-quality spherical 
powders, particularly in the medical products area, such as porous coatings 
for implants. Additionally, the Company is developing new innovative 
technology to produce finer size spherical powders that can be consolidated 
into fully dense parts. We are targeting commercial parts made from our 
titanium powders due to the growing commercial interest in this aerospace 
metal.

STARMET AEROCAST & COMCAST

    Over the past six years, ongoing development efforts on our patented 
Beralcast-Registered Trademark- technology for producing lightweight, 
precision castings for aerospace applications have resulted in a significant 
cost reduction using present equipment and installation of automated 
production equipment will result in further cost reductions that are expected 
to be significant.  This has significantly improved this exciting material's 
economic viability in numerous applications.  Our Beralcast-Registered 
Trademark- hardware is now in demonstration and prototype manufacture on its 
way to production for several new aerospace programs.  Having our patented 
alloys selected and proven as a reliable "bill of material" on specific 
military programs is of the utmost importance and a good indicator of future 
performance.

    Commercial applications for Beralcast-Registered Trademark- components have
a much faster but 

                                      3
<PAGE>

shorter product life cycle.  Commercial applications require materials that 
are cost effective and are reliably manufactured.  New computer disc drive 
armatures designed in Beralcast-Registered Trademark- now are being evaluated 
by four leading disc drive manufacturers.  In commercial applications, the 
ramp from demonstration quantities to production quantities is generally only 
18 months vs. 10 years for most military applications.  Now that substantial 
manufacturing cost savings have been demonstrated by aerospace applications 
we are rapidly approaching sizable production opportunities for several 
commercial applications.

COMMITMENT TO QUALITY

    During Fiscal 1997 the Company became the first small business in the 
United States to qualify for the US Army's highest Quality Certification.  
This ISO 9002 based quality system which the Army has called its Contractor 
Performance Certification Program required a two and a half year total 
company effort.  Broad-based employee teams have worked together to improve 
and document processes and procedures and then to develop charts and graphs 
to monitor ongoing performance.  Extensive employee participation in the 
measurement and review process has been essential to our success.  This 
never-ending process has a single goal of continuously increasing customer 
satisfaction.  In addition to receiving Army certification, the Company has 
been recommended for ISO 9002 Certification by an international registrar.  
We expect to receive the formal ISO 9002 certification in early Calendar 1998.

THE FUTURE

    The name change, creation of several new subsidiaries, the Army funding 
to remove a holding basin on our Concord, Massachusetts property, the 
increasing Beralcast-Registered Trademark- requirements including 

                                      4
<PAGE>

a growing number of commercial applications and the return to meaningful 
production volumes at Starmet CMI beginning in the second quarter of Fiscal 
1998, all position the Company well to continue growth and diversification. 
We have outstanding employees who very much join in the excitement of meeting 
our customers' needs today and tomorrow.

    We are committed to following a growth strategy and taking demonstrative
actions that will enhance shareholder value.                    

    Thank you for your continued support and confidence.

                        PROVIDING OUR SOLDIERS WITH THE 
                          BEST AMMUNITION IN THE WORLD

                                  Performance


    "Transition" describes our status in support of the Armed Forces for 
Depleted Uranium (DU) ammunition.  Starmet NMI has provided DU ammunition to 
all branches of the United States Armed Forces.  We are proud of our role in 
providing our soldiers with the best ammunition in the world.  When we were 
visited by two Desert Storm tank commanders this past year we were told 
emphatically that lives are saved when our soldiers are able to rely 
completely on the quality, consistency, and performance of DU ammunition.  
However, events in the former Soviet Union, combined with the effectiveness 
of the ammunition deployed in Desert Storm, lead the Army to the conclusion 
that fewer rounds needed to be stockpiled.  As we produce 120MM DU rounds for 
the M1A2 Abrams tank at a tenth of previous rates, the need to transition 
from the ordnance marketplace to the commercial marketplace is evident. A 
versatile material, DU is used in commercial applications ranging from 
shielding devices for the medical industry to counterweight materials in wide 
body aircraft. While facilities in Concord, MA previously used for DU 
penetrator manufacture are being cleaned and readied for production expansion 
of our patented Beryllium Aluminum alloy, Beralcast-Registered Trademark-, 
Starmet will continue to support the Army's DU ammunition needs with 
consolidation of facilities and technical expertise at CMI in Barnwell, SC.

metals into useable shielding products, refurbishing commercial and military 
aircraft counterweights, or producing feed materials for the Atomic Vapor 
Laser Isotope Separation process, CMI brings value to customers through 
technical excellence and proven technologies.  The answer to the question of 
how to manage the growing inventory of uranium hexafluoride may be found in 
DUCRETE-TM- shielding, a patented form of ultra dense concrete using uranium 
oxide briquettes as aggregate in concrete.  We have formed a partnership 
which ensures exclusive rights to DUCRETE-TM- shielding containers and 
barriers for use by nuclear utilities for mandated above-ground storage of 
spent fuel.  Respect for the environment, innovative technologies, a skilled 
workforce and room to grow on 340 acres in South Carolina position the 
CMI for success in the future.

                                 IS THE TITANIUM
                                  OF THE FUTURE

                                     Vision


    Cost-effective, light, durable, and flexible are words that can be used 
to describe Beralcast-Registered Trademark-'s advantageous use for aerospace 
components.  The commercial marketplace is equally demanding of such 
qualities in engineering materials.  Where production of commercial products 
advance at dizzying rates, engineers are increasingly pressured to design 
with smaller and lighter components manufactured by innovative suppliers.  
Today's premium golf club heads are investment cast or forged from Titanium 
and its alloys.  Titanium is twice the density of Beralcast-Registered 
Trademark- and offers less flexibility in its manufacture.  Some golfers tell 
us Beralcast-Registered Trademark- is the Titanium of the future. In the 
computer hardware market Beralcast-Registered Trademark- offers significantly 
better performance characteristics than conventional materials. For example, 
Beralcast-Registered Trademark- will allow a vast increase in the data 
storage capacity and retrieval of tomorrow's computer disc drives. Prototypes 
using Starmet's Beralcast-Registered Trademark- are currently being qualified 
for this use.  Other commercial applications for this material include those 
where a small premium can be paid for significantly enhanced performance and 
design flexibility. Imagine using Beralcast-Registered Trademark- instead of 
aluminum to enhance high speed assembly and inspection devices where 
Beralcast-Registered Trademark-'s vibration damping qualities can result in a 
five to ten fold performance improvement.

                            FOR CREATING PRODUCTS 

                                  Technology


    Metal powders can be used effectively in a variety of applications where 
exacting sizes, shapes, and cleanliness are important.  Clean cobalt chrome 
and titanium powders, made by our patented Plasma Rotating Electrode Process 
(PREP-TM-), are used in medical implants to effectively bond prosthetic 
devices to bone and tissue.  Uniform steel powders are used not only in 
photocopiers and sophisticated rapid prototyping applications, but in 
magnetic paint for children's books, wallpaper, and toys.  Materials that are 
difficult to fabricate from castings or forgings are candidates for powder.  
Oftentimes metallurgy approach castings are converted to powders, which are 
in turn, reconsolidated into semi-finished components with improved 
mechanical properties. Fine titanium powders consolidated into semi-finished 
components represent tomorrow's challenge for advanced metal powder-making 
technologies at Starmet Powders.  Combining a solid reputation for 
ultra-clean powder processing techniques with new and dedicated engineering 
resources, opens a world of possibilities for creating products.  We have 
realized that such possibilities exist even more clearly when we combine our 
resources with other innovative companies whose enthusiasm for producing high 
value powder metallurgy products matches our own.  We have a vision that 
includes consolidation of fine powders into complex shapes.

MANAGEMENT'S DISCUSSION 
AND ANALYSIS OF 
OPERATIONS

FISCAL 1997 COMPARED WITH FISCAL 1996

    Net sales decreased by $632,000 or 2% in fiscal 1997. Sales in the 
Uranium Services and Recycle industry segment decreased by $1,224,000 or 20%; 
sales in the Specialty Metal Products industry segment decreased by $560,000 
or 4% and sales in the Depleted Uranium Penetrator industry segment increased 
by $1,152,000 or 13%.  

    The decrease in the Uranium Services and Recycle industry segment was 
mainly due to lack of volume in depleted uranium products due to completion 
of a production contract for a foreign customer in fiscal 1996.  This 
decrease was partially offset by increases in AVLIS feedstock production for 
the United States Enrichment Corporation (USEC). The decrease in the 
Specialty Metal Products industry segment was a result of decreased volumes 
of beryllium products partially offset by an increase in commercial depleted 
uranium products. The increase in the Depleted Uranium Penetrator industry 
segment was the result of higher production volume of penetrator blanks  for 
a foreign customer and the revenue recognized pursuant to the Company's 
contract with the United States Army to remediate the holding basin facility 
(see Note 11).

    Gross profit (net sales and contract revenues less cost of sales) 
increased by $5,285,000 to $8,926,000 or 32% of sales as compared to 
$3,641,000 or 13% of sales for fiscal 1996. This increase in gross profit is 
primarily due to reduction of certain accruals in fiscal 1997 for site 
remediation and waste burial costs of $1,750,000 and a reduction of inventory 
reserves of $1,000,000. Also, gross profit for fiscal 1996 was reduced by an 
accrual of a $2,100,000 for anticipated fiscal 1997 operating losses associated
with CMI's production contracts. As of September 30, 1997 the accrual has 
been fully utilized.

    Selling, general and administrative expenses increased by $124,000 to 
$5,448,000. This increase was primarily due to additional

employees required to support the forecasted growth in business.  As a 
percentage of sales, these expenses remained at 19% as compared to the prior 
year.

    Company-sponsored research and development expenses increased by 49% or 
$433,000 to $1,309,000 for fiscal 1997. As a percentage of sales, these 
expenses were 5% as compared to 3% in fiscal 1996.

    Interest and other income/(expense), net, decreased to ($2,000) for the 
fiscal year as compared to ($89,000) for the prior year.  This decrease was 
mainly from the absence in fiscal 1997 of a restructuring fee associated with 
amendments to the Company's credit facility during the third quarter of fiscal 
1996.

    Interest expense decreased by $91,000 to $296,000 as compared to fiscal 
1996.  This decrease was primarily the result of higher interest rates and 
fees associated with out standing debt during fiscal 1996. 

IMPACT OF YEAR 2000 ISSUE

    The Year 2000 issue is the result of computer programs being written using 
two digits rather than four to define the applicable year. Any of the 
Company's computer programs that have data-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 miscalculations causing disruptions of operations, 
including, among other things, a temporary inability to process transactions, 
send invoices, or engage in similar normal business activities.

    The Company is in the process of installing a new accounting software 
system. Management believes that subject to successful installation of the new 
accounting system, the Year 2000 issue will not have a material adverse impact 
to the Company's operations or financial position.

INCOME TAXES

    Income taxes provided during 1997 and 1996 were at effective rates of 2% 
and 0%, respectively. The 1997 effective rate of 2% differs from the 
statutory rate of 34% due to a reduction in the valuation allowance 
associated with to the benefit of net operating loss carryforwards.

INFLATION

    Inflation has not had a material impact on the Company's cost of doing 
business. Management attempts to protect the Company by adjusting prices 
where market conditions permit and by reviewing and improving production 
processes where possible.  Price escalation clauses also are negotiated into 
long-term contracts when possible.

LIQUIDITY AND CAPITAL RESOURCES

    During the year ended September 30,

1997, the Company's primary sources of capital have been shareholder notes 
payable and borrowings through its revolving credit facility with its 
commercial bank.  On August 7, 1997, the Company entered into a Third 
Amendment to the Credit Agreement dated March 31, 1995, which increased the 
principal amount of the credit facility from $4.25 million to $6.55 million.  
The increase in the credit facility was to provide the Company with a letter 
of credit to satisfy its financial assurance requirements as defined by DHEC 
in connection with the Company's license to operate in South Carolina. 

     On October 1, 1997, the Company amended and restated its Credit 
Agreement dated March 31, 1995, as amended, with its lender, pursuant to the 
terms of an Amended and Restated Credit Agreement ("Credit Agreement").  The 
total amount of the credit thereunder available to the Company remained at 
$6.55 million, and the Company and all its subsidiaries became borrowers 
under the Credit Agreement.  The Credit Agreement is secured by an Amended 
and Restated Joint Security Agreement, whereby the Company and its 
subsidiaries granted to the lender a first priority security interest in all 
accounts, inventory and general intangibles.  The Company is subject to 
certain operating and financial covenants, including minimum tangible 
capital, as defined and net income requirements in connection with the credit 
facility.   

     The Company has entered into a First Amendment to the Credit Agreement 
with its lender dated December 9, 1997, which provides for an increase in the 
credit facility to $8.05 million. 

    On December 29, 1997, the Company entered into a Second Amendment to the 
Credit Agreement which provides for the following; (a) an increase in the 
total amount of credit available to the Company from $8.05 million to $9.55 
million; (b) the terms of repayment for the line of credit have been revised 
so that $1.5 million is due July 1, 1998, $1.5 million is due October 1, 1998 
and the balance, $3.0 million is due on February 28, 1999; and (c) all previous
events of non-compliance with the Credit Agreement have been waived and 
certain financial covenants have been amended. 

    In consideration of the Second Amendment to the Credit Agreement the 
Company has issued to the lender a warrant to purchase 25,000 shares of 
common stock at the ten day average of fair market value as of December 29, 
1997. These warrants have a seven year exercise period. The Company also paid 
its lender $15,000 upon execution of the Amendment.

    During the quarter ended September 30, 1997, the Company sold $500,000 of 
subor-

dinated debt, with warrants to purchase common stock, to a shareholder, 
bringing the principal amount of such subordinated debt to $1,350,500.  This 
additional capital was provided to the Company in support of growth in new 
product areas.  The Company also issued convertible debt in the original 
principal amount of $900,000 to certain shareholders on December 23, 1997. 
(See note 6 of the notes to consolidated financial statements for details of 
the Credit Agreement and subordinated debt issued to certain of the Company's 
shareholders).

    The Company has outstanding approximately $180,000 in principal amount on 
industrial revenue bond indebtedness related to the Starmet CMI facility.  
The Company also has a term note in the amount of $370,000 with Palmetto 
Federal Savings Bank of South Carolina.  This loan is secured by a mortgage 
on Starmet CMI's South Carolina property.  The Company is a guarantor under 
the Palmetto loan.

    The Company is expanding its facilities by adding new equipment and 
modifying manufacturing floor space to accomodate changing product lines and 
customer demands. The Company anticipates that this will require capital 
expenditures totaling approximately $2,000,000 during fiscal 1998.

    The Company did not declare any cash dividends during its last three 
fiscal years.  The Company does not expect to pay cash dividends in the next 
fiscal year.  Future cash dividends, if any, would be paid on an annual 
basis, the amount of which is subject to the determination and approval of 
the Company's Board of Directors.  The Credit Agreement also prohibits the 
declaration or payment of dividends without the lender's consent.

    The Company believes, based on assumptions concerning backlog fulfillment 
and the expected timing of new orders, that its cash from operations together 
with currently available credit facilities, will be sufficient to sustain 
operations in 1998 and to fund required capital expenditures.

FISCAL 1996 COMPARED WITH FISCAL 1995

    Net sales increased by $9,910,000 or 53% in fiscal 1996. Sales in the 
Uranium Services and Recycle industry segment increased by $1,220,000 or 25%; 
sales in the

Specialty Metal Products industry segment increased by $1,628,000 or 13% and 
sales in the Depleted Uranium Penetrator industry segment increased by 
$7,062,000 or 412%.  The increase in the Uranium Services and Recycle 
industry segment was mainly due to increases in AVLIS feedstock production 
for the United States Enrichment Corporation (USEC). The increase in the 
Specialty Metal Products industry segment was a result of higher sales of 
beryllium products and commercial depleted uranium. The increase in the 
Depleted Uranium Penetrator industry segment was the result of higher large 
caliber penetrator production sales.

    During the third quarter of fiscal 1996, the Company reduced its 
workforce from 55 to 24 employees at the Carolina Metal's (CMI) facility due 
to reduced production requirements resulting from the completion of a 
multi-year contract for the manufacture of depleted uranium for a foreign 
customer and the lack of anticipated new orders.  The Company had expected to 
obtain substantial orders from USEC and the Department of Energy (DoE) in the 
second half of fiscal 1996.  These orders have yet to be materialized and as 
a result CMI is operating at approximately 40% capacity on a one-shift basis 
and is expected to do so through most of fiscal 1997.  In the fourth quarter 
of fiscal 1996 the Company established a $2,100,000 reserve for estimated 
fiscal 1997 losses associated with CMI's current production contracts.  The 
Company is obligated to complete these contracts, which are fixed price. The 
Company continues to pursue alternate production contracts and believes that 
significant orders eventually will be received for work at the CMI facility.  
In the event that the prospects for greater utilization of the CMI facility 
do not improve the Company will reevaluate the carrying value of its CMI 
facility during fiscal 1997, which could result in a further write-

down of plant assets. 

    Gross profit (net sales and contract revenues less cost of sales) 
increased by $309,000 to $3,641,000 or 13% of sales as compared to $3,332,000 
or 18% of sales for fiscal 1995. This increase in gross profit is primarily 
due to increased sales volume during fiscal 1996.  As a percentage of sales, 
the decrease in gross profit is primarily due to the establishment of a 
$2,100,000 reserve for estimated losses associated with CMI's production 
contracts.

    Selling, general and administrative expenses increased by $507,000 to 
$5,324,000. This increase was primarily due to additional employees required 
to support the growth in business.  As a percentage of sales, these expenses 
decreased to 19% as compared to 26% for the prior year, as a result of sales 
increasing at a higher rate than expenses.

    Company-sponsored research and development expenses increased by 100% or 
$437,000 to $876,000 for fiscal 1996. As a percentage of sales, these 
expenses were 3% as compared to 2% in fiscal 1995.

    Interest and other income, net, decreased to $(476,000) for the fiscal 
year as compared to $232,000 for the prior year.  This decrease was mainly 
from a $150,000 restructuring fee associated with amendments to the Company's 
credit facility during the third quarter of fiscal 1996 and a gain of 
$175,000 recognized during the second quarter of fiscal 1995 on the sale of 
an office building.

    Interest expense increased by $37,000 to $387,000 as compared to fiscal 
1995.  This increase was primarily the result of higher interest rates and 
fees associated with outstanding debt during fiscal 1996.

    During fiscal 1995, the Company realized a $585,000 extraordinary gain, 
net of taxes of $10,000, on the early extinguishment of debt.

FISCAL YEARS

    References in these financial statements to 1997, 1996, and 1995 are for 
the fiscal years ended September 30, 1997, September 30, 1996, and

all share and per share information have been restated to reflect a 2 for 1 
stock split effective in April 1997.

REVENUE RECOGNITION

    Revenues are recorded when products are shipped, except for revenues on 
long-term contracts, which are recorded on the percentage-of-completion 
method. The percentage-of-completion method is used for research and 
development contracts and for production contracts, which require significant 
amounts of initial engineering and development costs.  The 
percentage-of-completion is determined by relating the actual number of 
contract units completed to date to the total units to be completed under the 
respective contract or by relating total costs incurred to total estimated 
costs at completion.  When the estimated total cost on a contract indicates a 
loss, the Company's policy is to record the entire loss currently.  
Performance incentives and penalties incorporated in certain government 
contracts are recognized when incentives are earned or awarded or when 
penalties are incurred or assessed.  Contract revenues include fees resulting 
from facilitization contracts with the U. S. Army (contracts to establish 
production capacity through the purchase and installation of equipment to be 
owned by the U.S. Army).  Costs associated with these contracts, exclusive of 
the costs to purchase the equipment ($0 in 1997, 1996 and in 1995) are 
included in cost of sales.  The consolidated balance sheets do not include 
the cost of this U.S. Army-owned equipment.

CASH AND CASH EQUIVALENTS

    Cash and cash equivalents are

recorded at cost, which approximates market value.  Cash equivalents include 
certificates of deposit with a maturity of one year or less.

INVENTORIES

    Inventories are stated at the lower of cost (first-in, first-out) or 
market and include materials, labor, and manufacturing and engineering 
overhead.

PROPERTY, PLANT, AND EQUIPMENT

    Property, plant, and equipment are recorded at the lower of cost or net 
realizable value.  For financial reporting purposes, the Company provides 
depreciation on the straight-line method over the estimated useful lives of 
the assets, which are as follows:


    Buildings.....................................   20 - 30 years
    Machinery, equipment, and fixtures............    3 - 10 years



    Maintenance and repairs are charged to operations as incurred; renewals 
and betterments are capitalized.  When property, plant, and equipment are 
sold, retired or disposed of, the asset cost and accumulated depreciation are 
removed from the accounts, and the resulting gain or loss is included in 
operations.  

    In Fiscal 1997, the Company adopted the Financial Accounting Standards 
Board ("FASB") issued Statement of Financial Accounting Standards (SFAS) No. 
121, "Accounting for the Impairment of Long-Lived Assets and of Long-Lived 
Assets to be Disposed of."  This statement requires a review of impairment 
for long-lived assets and certain identifiable intangibles to be held and 
used by an entity whether events or changes in circum-

                                     32


<PAGE>

stances indicate that the carrying amount of the assets may not be 
recoverable.  An impairment loss is recognized if the sum of the expected 
future cash flows to result from the use and eventual disposition of the 
asset is less than the carrying amount of the asset.  The amount by which the 
carrying amount of the asset exceeds the fair value less costs to sell, is an 
impairment loss.  The effect of adopting this statement was not material to 
the Company's financial position or results of operation.  

    In the fourth quarter of fiscal 1996, the Company established a $2,100,000
reserve for estimated losses associated with Starmet CMI's production contracts.
The Company was obligated to complete these contracts, which were fixed price. 
The contracts have been completed and the reserve is $0 as of September 30, 
1997.
                                                              
INCOME TAXES

    The Company accounts for income taxes in accordance with SFAS No. 109, 
"Accounting for Income Taxes."  Accordingly, the Company recognizes deferred 
income taxes based on the expected future tax consequences of differences 
between the financial statement basis and the tax basis of assets and 
liabilities, calculated using enacted tax rates in effect for the year in 
which the differences are expected to be reflected in the tax return.  The 
Company records a valuation allowance against any net deferred tax assets 
whose realizability is uncertain.

    The deferred federal and state income taxes result primarily from using 
accelerated depreciation on property, plant, and equipment for income tax 
reporting purposes and from establishing reserves which are not currently

deductible for income tax purposes, respectively.

RESEARCH AND DEVELOPMENT COSTS

    Research and development costs are expensed as incurred.  Research and 
development incurred under customer contracts are expensed through cost of 
sales in the period incurred.

INCOME (LOSS) PER COMMON AND COMMON EQUIVALENT SHARES

    The Company currently calculates earnings per common share under 
Accounting Principles Board Opinion (APB) No. 15, "Earnings Per Share." 
Income/(loss) per share was computed by dividing the net income by the 
weighted average number of shares of common stock outstanding during each 
year. Common stock equivalents (stock options and stock warrants) were 
considered in the computation of earnings per common and common equivalent 
share for 1997.  Stock options and stock warrants were not considered in 
computing the loss and income per share in 1996 and 1995, as the effect would 
have been antidilutive.

RECLASSIFICATIONS

    Certain amounts previously reported in the consolidated financial 
statements have been reclassified to conform to the 1997 presentation.

NEW ACCOUNTING STANDARDS

    In March 1997, the Financial Accounting Standards Board issued SFAS No. 
128 "Earnings Per Share," which establishes standards for computing and 
presenting earnings per share for entities with publicly held common stock or 
potential common stock.  SFAS No. 128 is effective for periods ending after 


            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS, CONTINUED
                                     34

<PAGE>

December 15, 1997 and early adoption is not permitted.  SFAS No. 128 replaces 
primary earnings per share with "basic earnings per common share."  Basic 
earnings per common share is computed by dividing net income by the weighted 
average number of shares of common stock outstanding during the year.  No 
dilution for any potentially dilutive securities is included.  In addition, 
SFAS No. 128 replaces fully diluted earnings per common share with "diluted 
earnings per common share."  Dilution for options and warrants under SFAS No. 
128 is computed using the average share price of the Company's common stock 
for the period, rather than the more dilutive greater than average share 
price or end-of-period share price required by APB No. 15.   For fiscal years 
1997, 1996, and 1995 there would be no material change from primary and fully 
diluted earnings per common share to basic and diluted earnings per share 
under SFAS No. 128.

USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS

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

DISCLOSURES ABOUT THE FAIR VALUE OF FINANCIAL INSTRUMENTS

    The Company's financial instruments consist mainly of cash and cash

<PAGE>

equivalents, restricted cash, accounts receivable, notes receivable from 
officers, accounts payable and notes payable.  The carrying amounts of the 
Companys cash and equivalents, restricted cash accounts receivable, notes 
receivable from officers and accounts payable approximate their fair value 
due to the short-term nature of these instruments.  The carrying value of the 
notes payable also approximates the fair value, based on rates available to 
the Company for debt with similar terms and remaining maturities.

    As of September 30, 1997, approximately $6.9 million of the Company's 
inventory consists of Depleted Uranium (DU) in various stages of production. 
This amount consists of both value-added costs to government owned  material, 
($3.6 million), which is used for U.S. Military contracts and for material 
which the Company has acquired from other sources, ($3.3 million). During 
fiscal 1995 the U.S. Army notified the Company that the Army would provide 
the DU for production for the most recent penetrator contract.  Management 
strongly believes that the Army is responsible to compensate the Company for 
the value-added costs of this material and that at a minimum the Army would 
allow the Company to use this material for non U.S. military contracts at no 
additional cost to the Company. Management is pursuing several Department of 
Energy programs that would require more DU over the next several years than 
the Company currently has on hand. Management believes that the carrying cost 
of the inventory on hand

will be fully realizable through these possible programs or from its ongoing 
usage for U.S. and foreign military procurements, however it is uncertain how 
much of the inventory balance will be utilized in fiscal 1998. During 1997, 
the Company reduced inventory reserves by approximately $1,000,000 which were 
deemed no longer necessary.

CREDIT FACILITY

    On August 7, 1997 the Company and its commercial bank, State Street Bank 
& Trust Company signed the Third Amendment to their credit agreement date 
March 31, 1995 (as amended, the "Credit Agreement").  The Third Amendment 
increases the Company's credit facilities from $4.25 million to $6.55 
million, with a maturity date of February 28, 1998.  The $6.55 million 
consists of $3.55 million of letters of credit and $3.0 million credit line 
for working capital. Borrowings under the Credit Agreement bear interest at 
the prime rate plus 1/2 of 1%.  The Company also pays a fee of 1/2

of 1% on the unused portion of the credit facilities.


    As of September 30, 1997 the Company was not in compliance with certain 
financial covenants contained in the Credit Agreement. 

    On October 1, 1997, the Company amended and restated the Company's 
revolving credit facility with its lender, pursuant to the terms of an 
Amended and Restated Credit Agreement ("Credit Agreement"), which amended and 
restated the Credit Agreement dated March 31, 1995.  The total amount of the 
credit available to the Company remained at $6.55 million, and the Company 
and all its subsidiaries became borrowers under the Credit Agreement.  The 
Credit Agreement is secured by an Amended and Restated Joint Security 
Agreement, whereby the Company and its subsidiaries granted to the lender a 
first priority security interest in all accounts, inventory and general 
intangibles.  The Company is subject to certain operating and financial 
covenants, including minimum tangible capital, as defined and net income 
requirements in connection with the credit facility.   

    The Company has entered into a First Amendment to the Credit Agreement 
with its lender dated December 9, 1997, which provides for an increase in the 
credit facility to $8.05 million.   

    On December 29, 1997, the Company entered into a Second Amendment to the 
Credit Agreement which provides for the following; a. the total amount of 
credit available to the Company increased from $8.05 million to $9.55 
million; b. the terms of repayment for the line of credit have been revised 
as such, $1.5 million is due July 1, 1998, $1.5 million is due October 1, 
1998 and the balance, $3.0 million is due in February 1999; c. all previous 
events of non-compliance with the Credit Agreement have been waived and 
certain financial covenants have been amended.

    In consideration of the Second Amendment to the Credit Agreement the 
Company has issued to their lender a warrant to purchase 25,000 shares of 
common stock at the ten day average of fair market value as of December 29,
1997. The Company also paid its lender $15,000 upon execution of the 
Amendment.

    As of September 30, 1997, and December 29, 1997, $1.7 million and $4.5 
million were outstanding under the line of credit, respectfully.   The 
Company had $3.55 million letters of credit outstanding, at December 29, 
1997.  

NOTES PAYABLE TO SHAREHOLDERS

    On January 10, 1996, the Company issued $500,500 in principal amount of its
10% Convertible Subordinated Debentures, the principal amount of which is
convertible at the option of the holder into shares of the Company's Common
Stock at the rate of $5.945 per share.  The original maturity date of these
Debentures, June 10, 1997, has been extended by the holders pursuant to certain
letter agreements until December 10, 1998.  These Debentures were issued to
persons who are significant shareholders of the Company or related to such
persons.  

    On September 16, 1996 the Company issued an additional $350,000 in 
principal amount pursuant to its 10% Subordinated Debentures due December

10, 1998 which were issued to certain significant shareholders of the 
Company. In consideration for the Debentures, the holders were issued 
three-year warrants to purchase an aggregate of 42,000 shares of common stock 
at an exercise price of $7.50 per share, subject to antidilution adjustments.

    On September 22, 1997 the Company issued an additional $500,000 in 
principal amount pursuant to its 10% Subordinated Debentures due December 10, 
2000 which were issued to a shareholder of the Company.  In consideration for 
the Debentures, the holders were issued three-year warrants to purchase an 
aggregate of 60,000 shares of common stock at an exercise price of $17.875 
per share, subject to antidilution adjustments.

    On December 23, 1997 the Company issued an additional $950,000 in 
principal amount pursuant to its 10% Convertible Subordinated Notes due 
December 31, 1999 which were issued to certain significant shareholders of 
the Company. The principal amount of the Notes are convertible at the option 
of the holder into shares of the Company's Common Stock at the rate of $21.50 
per share.

THE INDUSTRIAL REVENUE BONDS

     The Industrial Revenue Bonds (the "IRBs") outstanding consists of one 
note issue.  The interest rates on this note is 66.5% of the lenders bank's 
prime interest rate.  This note is secured by property, plant and equipment.

    The IRBs contain restrictive covenants including, among others, a 
requirement to maintain minimum working capital, consolidated net worth and a 
minimum current ratio.  As of September 30, 1997, the Company was not in 
compliance with certain of these financial covenants.  The Company has 
received a waiver from the trustee for these events of non-compliance. 

    Maturities of long term obligations subsequent to September 30, 1997 are: 
1998 -$1,885,000, 1999 - $1,052,000; 2000 - $655,000; thereafter $73,000.

which was the approximate market value of the Company's common stock at the 
date of the transactions.

    In consideration of the Second Amendment to the Credit Agreement the 
Company issued to their lender a warrant to purchase 25,000 shares of common 
stock of the Company at the average fair market value for the ten days ended 
December 29, 1997.

PRO FORMA STOCK-BASED COMPENSATION EXPENSE

    In October 1995, the FASB issued SFAS No. 123, "Accounting for Stock-Based 
Compensation," which sets forth a fair-value based method of recognizing 
stock-based compensation expense.  As permitted by SFAS No. 123, the Company 
has elected to continue to apply APB No. 25 to account for its stock-based 
compensation plans.  Had compensation cost for awards in 1997 and 1996 under 
the Company's stock-based compensation plans been determined based on fair 
value at the grant dates consistent with the method set

forth under SFAS No. 123, the effect on the Company's net income and earnings 
per share would have been as follows:

In thousands except per share amounts            1997            1996
                                              ---------       ----------
Net Income (Loss)                               $1,482         $(3,037)
    As reported                                  1,373          (3,100)
    Pro forma
Primary/Fully Diluted Earnings Per Share:
    As reported                                  $0.30          $(0.64)
    Pro forma                                     0.28           (0.65)


    Because the method prescribed by SFAS No. 123 has not been applied to 
options granted prior to October 1, 1995, the resulting pro forma 
compensation expense may not be representative of the amount to be expensed 
in future years. Pro forma compensation expense for options granted is 
reflected over the vesting period; therefore future proforma compensation 
expense may be greater as additional options are granted.

    The fair value of each option granted was estimated on the grant date 
using the Black-Scholes option pricing model with the following weighted 
average assumptions: risk-free interest rates of 6.19% to 6.21% and 5.38% to 
6.50% for 1997 and 1996, respectively, expected life of 10 years, expected 
volatility of 51% and 54% for 1997 and 1996, respectively.

9. PENSION PLAN

    The Company has a defined benefit pension plan designed to provide 
retirement benefits to all employees.  This plan provides pension benefits 
that are based on the employee's salary and years of service.  The Company's 
policy is to fund the plan at a level within the range required

by applicable regulations.

    The Company's net pension cost for 1997, 1996, and 1995 was $375,000, 
$281,000, and $165,000, respectively.  During 1997, the Company used the 
weighted average discount rate of 8.0%.  Net pension cost for the Company's 
defined benefit plan included the following components:

10. POSTRETIREMENT BENEFITS

    Effective the beginning of fiscal 1994 the Company adopted Statement of  
Financial Accounting Standards No. 106 ("SFAS 106"), "Employers' Accounting 
for Postretirement Benefits Other Than Pensions".  The statement requires 
companies

to accrue the cost of postretirement health care and life insurance benefits 
within the employees' active service periods. 

    The Company provides employees who retired from the Company prior to 
January 1, 1993, with at least ten years of service and under the age of 65, 
with Group Health Insurance on a cost-sharing basis.  Coverage for an 
employee's spouse or dependents will also continue under this plan until the 
employee has reached age 65 at which time, the coverage ceases.  In addition, 
the Company provides the same employees who are at least 62 years of age with 
life insurance equal to their ending annual salary up to a maximum of $50,000.

    For employees who retire after January 1, 1993, the postretirement 
benefits do not include health insurance.  In addition, the life insurance 
benefit, up to a maximum of $50,000, is provided for one year after 
retirement.

    The accumulated benefit obligation of these benefits as of September 30, 
1997, is approximately $767,000 ($5,000 for medical insurance and $762,000 
for life insurance).  Plan assets of $401,000 in cash reserves are on hand 
with an insurance company to partially cover the cost of the life insurance 
benefits. The Company adopted the new standard prospectively as of October 1, 
1993, and is amortizing the transition obligation of $456,000,  over three 
years for the medical insurance benefits and fifteen years for the life 
insurance benefits.

11. COMMITMENTS AND CONTINGENCIES 

EXPANSION

    The Company is expanding its facilities by adding new equipment and 
modifying manufacturing floor space to accommodate changing product lines and 
customer demands.  The Company anticipates that this will require capital 
expenditures totaling approximately $2,000,000 during fiscal 1998.  These 
capital needs will be funded through cash flow from operations, shareholder 
notes and long-term debt. There is no guarantee that the Company will be able 
to obtain adequate financing at acceptable terms to meet these needs.

WASTE DISPOSAL

    In the process of manufacturing depleted uranium products, the Company 
generates low-level radioactive waste (LLRW) that must be disposed of at 
sites licensed by federal, state, and local governments.  At present, there 
is one licensed commercial repository in the United States available for use 
by the Company.  For LLRW originating in Concord, no site currently exists 
and provisions have been made to accommodate interim storage.  State 
government has the 

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS, CONTINUED


                                     48


<PAGE>


responsibility to implement the provisions of the federal Low-Level Waste 
Policy Amendments Act and provide a state solution for Massachusetts 
companies that generate this type of waste.  Management is of the opinion 
that an extended period of storage can be accommodated within existing 
buildings and in an environmentally safe manner acceptable to all regulatory 
agencies until such time as an acceptable site is identified.

HOLDING BASIN FACILITY

    For a number of years, ending in 1985, the Company disposed of 
manufacturing-related depleted uranium waste and the associated spent acid 
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 
leaking 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 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 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 a fixed price contract, for approximately $6.2 million for 
remediation of the holding basin and the Company entered into a fixed price 
contract 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 in addition to the Basin 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 plans), under an existing 
contract. D&D costs for the Company's CMI facility are adequately covered by 
the existing letter of credit, which is currently in place to assure funding 
for potential D&D obligations to date. 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.

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

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 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.

    The Uranium Services and Recycle segment includes the manufacture of 
depleted uranium products (non-penetrator) and the recycle of low level 
radioactive metal. The Specialty Metal Products segment includes a large 
assortment of metal products fabricated using foundry, extrusion, and 
machining capabilities, including commercial depleted uranium products, and 
involves the production and sale of various metal powders manufactured by the 
Company's patented Rotating Electrode Process. Operations in the Depleted 
Uranium Penetrator industry segment include the production of various 
penetrators (a component of armor-piercing ammunition used in certain U.S. 
military gun systems) which are sold to a department of the U.S. Department 
of Defense (DOD), to prime contractors manufacturing such ammunition for the 
DOD or to foreign military operations. Revenues derived from contract 
research and development activities have been included in the above segments 
based on the nature of the product.

    Net sales and contract revenues by industry segment include sales to 
unaffiliated customers (intersegment sales are not significant).  A 
significant portion of the Company's revenues has been derived from five 
major customers (see Note 1). Sales to United States Enrichment Corporation 
are included in the Uranium Services & Recycle industry segment. Sales to 
Royal Ordnance and Primex Technologies are included in the depleted Uranium 
Penetrators industry segment. Sales to Lockheed Martin and Lockheed Idaho 
Falls are included in the Specialty Metal Products industry segment.

    Due to the utilization among segments of common production facilities and 
equipment and the involvement of a single management organization in all 
phases of the Company's operations, nec-

essary allocations have been made based on estimates which management 
believes to be reasonable.

    Operating income includes net sales and contract revenues less operating
expenses allocated to the individual segments.  General corporate expenses
represent expenses which are not of an operating nature and, therefore, are not
allocable to industry segments.

    Identifiable assets shown include accounts receivable, inventory, and 
plant and equipment that have been allocated to each of the Company's 
industry segments. Corporate assets consist primarily of cash and other 
assets.

TO THE BOARD OF DIRECTORS AND STOCKHOLDERS OF STARMET CORPORATION:
     
     We have audited the accompanying consolidated balance sheets of Starmet 
Corporation (formerly known as 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 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.

COMMON STOCK INFORMATION

    The Company's common stock is traded on the NASDAQ Market under the 
symbol STMT. As reported by a principal market maker for the stock, the high 
and low bid prices for the three years ended September 30 are reflected in 
the following table. This information reflects inter-dealer prices, without 
retail mark-up, mark-down or commissions and may not represent actual 
transactions.

    As of September 30, 1997, there were approximately 300 holders of record 
of the Company's Common Stock.  The Company believes th actual number of 
beneficial owners of the Company's Common Stock is greater because a large 
number of shares are held in custodial or nominee accounts.

    The Company did not declare any cash dividends during its last two fiscal 
years. Given the Company's current cash flow situation, the Company does not 
expect to pay cash dividends in the next year.  Future cash dividends, if 
any, would be paid on an annual basis, the amount of which is subject to the 
determination and approval of the Company's Board of Directors.  The 
Company's loan agreement with a bank prohibits the declaration of dividends 
without the bank's consent.
