                               PROSPECTUS SUMMARY
 
  The following summary is qualified in its entirety by the more detailed
information and Consolidated Financial Statements and Notes thereto appearing
elsewhere in this Prospectus or incorporated by reference herein. Unless
otherwise indicated, all share and per share data and related information in
this Prospectus have been adjusted to reflect a three-for-two split of the
Common Stock effected on February 10, 1995 as a 50% stock dividend distributed
to all shareholders of record as of January 20, 1995. Unless otherwise
indicated, the information in this Prospectus assumes that the Underwriters'
over-allotment option will not be exercised.
 
                                  THE COMPANY
 
  Altron Incorporated ("Altron" or the "Company") is a leading contract
manufacturer of interconnect products used in advanced electronic equipment.
The Company manufactures complex products in the mid-volume sector of the
electronic interconnect industry. Altron's products generally require greater
engineering and manufacturing expertise than mass-produced, less complex
products. The Company manufactures custom-designed backplanes, surface mount
assemblies and total systems, as well as multilayer, high density printed
circuit boards. Altron works closely with its customers from the early stages
of product design and development. The Company provides original design,
engineering prototype, preproduction and volume production capabilities.
 
  Altron is benefitting from the trend by original equipment manufacturers
("OEMs") to outsource their manufacturing and concentrate their resources on
research, development, sales and marketing. The Company believes that the trend
towards increased reliance by OEMs on independent manufacturers reflects the
OEMs' recognition that, for complex electronic interconnect products,
independent manufacturers can provide greater specialization, expertise,
responsiveness and flexibility and can offer shorter delivery cycles than can
be achieved by internal production.
   
  Altron's strategy is to continue to use its well established multilayer, high
density printed circuit board manufacturing and engineering capabilities to
further expand into the rapidly growing contract manufacturing business,
providing products and services including backplanes, surface mount assemblies,
power supplies and total systems. Key elements of this strategy include
providing its customers with the highest levels of quality, superior service
and leading-edge technology. In fiscal 1994, approximately 61% of Altron's net
sales were attributable to value added contract manufacturing, with the
remaining 39% of net sales attributable to printed circuit board manufacturing.
Value added contract manufacturing sales for the first quarter of 1995 were 73%
of net sales, and printed circuit board manufacturing sales were 27% of net
sales.     
 
  Altron believes its capabilities both in manufacturing multilayer, high
density printed circuit boards and in providing value added contract
manufacturing services position the Company to serve high growth OEMs in the
rapidly changing electronics markets. Altron's OEM customers include a
diversified base of manufacturers in the telecommunications, data
communications, computer, industrial and medical systems segments of the
electronics industry, such as AT&T Corp., Cabletron Systems, Inc., Cascade
Communications Corp., Cisco Systems, Inc., Data General Corporation, EMC
Corporation, General Datacomm Industries, Inc., General Electric Company,
Hewlett-Packard Company, Motorola, Inc., Pyramid Technology Corporation,
Siemens Rolm Communications, Inc., Silicon Graphics, Inc., and Stratacom, Inc.
 
  The Company markets its products and services through its marketing and
customer service organization of 39 employees, and through 17 independent sales
representative organizations located in the major electronics market areas in
the United States. Altron operates three manufacturing plants totaling 285,000
square feet located in Massachusetts and Northern California, two of the major
electronics centers in the United States. The Company's two principal plants
are ISO 9002 registered.
 
  In June 1994, Altron Systems Corporation, a wholly-owned subsidiary of
Altron, acquired substantially all of the assets of Astrio Corporation
("Astrio"), a contract manufacturer. In December 1994, Altron combined its West
Coast systems manufacturing operations with those of Astrio in a new, expanded
manufacturing facility in Fremont, California.
 
  The Company is a Massachusetts corporation and was organized in 1970. Its
principal executive offices are located at One Jewel Drive, Wilmington,
Massachusetts 01887; its telephone number is (508) 658-5800.

                                  RISK FACTORS
 
  An investment in the shares of Common Stock offered hereby involves a high
degree of risk. Investors should carefully consider the following risk factors
as well as other information set forth in this Prospectus.
 
  DEPENDENCE ON ELECTRONICS INDUSTRY. Altron's customers are manufacturers in
the telecommunications, data communications, computer, industrial and medical
systems segments of the electronics industry. These industry segments, as well
as the electronics industry as a whole, are subject to rapid technological
change and product obsolescence. Discontinuance or modification of products
containing components manufactured by Altron could adversely affect the
Company's results of operations. The electronics industry is also subject to
economic cycles and has experienced and is likely in the future to experience
downturns. A downturn in the electronics industry could have a material adverse
effect on Altron's business, financial condition and results of operations. See
"Business--Customers and Markets."
 
  VARIABILITY OF CUSTOMER REQUIREMENTS; NATURE OF CUSTOMER COMMITMENTS ON
ORDERS. The level and timing of orders placed by the Company's OEM customers
vary due to customer attempts to manage inventory, changes in the OEMs'
manufacturing strategy and variation in demand for customer products. The
Company typically does not obtain long-term purchase orders or commitments but
instead works with its customers to anticipate the future volume of orders.
Based on such anticipated future volumes, the Company makes commitments
regarding the levels of business that it will seek and accept, the timing of
production schedules and the levels and utilization of personnel and other
resources. A variety of conditions, both specific to the individual customer
and generally affecting the customer's industry, may cause customers to cancel,
reduce or delay orders that were either previously made or anticipated.
Generally, customers may cancel, reduce or delay purchase orders and
commitments without penalty, except for payment for work and materials expended
through the cancellation date. Significant or numerous cancellations,
reductions, or delays in orders by a customer or group of customers could
adversely affect the Company's results of operations. See "Business--Customers
and Markets."
 
  FLUCTUATIONS IN OPERATING RESULTS. The Company's results of operations have
varied and may continue to fluctuate significantly from period to period,
including on a quarterly basis. Operating results are affected by a number of
factors, including timing of orders from and shipment to major customers, the
volume of orders as related to the Company's capacity, timing of expenditures
in anticipation of future sales, economic conditions in the electronics
industry and the mix of products. Operating results can also be significantly
influenced by the development and introduction of new products by the Company's
customers.
 
  The Company's customers generally require short delivery cycles, and a
substantial portion of the Company's backlog is typically scheduled for
delivery within 120 days. Quarterly sales and operating results therefore
depend in part on the volume and timing of bookings received during the
quarter. Backlog fluctuations affect the Company's ability to plan production
and inventory levels, which could lead to fluctuations in operating results. A
significant portion of the Company's operating expenses are relatively fixed in
nature and planned expenditures are based in part on anticipated orders. Any
inability to adjust spending quickly enough to compensate for any revenue
shortfall may magnify the adverse impact of any such revenue shortfall on the
Company's results of operations. Results of operations in any period should not
be considered indicative of the results for any future period, and fluctuations
in operating results may also result in fluctuations in the price of the
Company's Common Stock. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
  TECHNOLOGICAL CHANGE AND PROCESS DEVELOPMENT. The market for the Company's
manufacturing services is characterized by rapidly changing technology and
continuing process development. The future success of the Company's business
will depend in large part upon its ability to maintain and enhance its
technological capabilities, develop and market manufacturing services which
meet changing customer needs and successfully anticipate or respond to
technological changes in manufacturing processes on a cost-effective and timely
basis. Although management believes that the Company's operations utilize the
assembly and
 
                                       5
<PAGE>
 
testing technologies and equipment currently required by the Company's
customers, there can be no assurance that the Company's process development
efforts will be successful or that the emergence of new technologies, industry
standards or customer requirements will not render the Company's technology,
equipment or processes obsolete or uncompetitive. In addition, to the extent
that the Company determines that new assembly and testing technologies and
equipment are required to remain competitive, the acquisition and
implementation of such technologies and equipment are likely to continue to
require significant capital investment by the Company. There can be no
assurance that this capital will be available in the future. See "Business--
Electronic Interconnect Industry Overview," "--Business Strategy" and "--
Manufacturing Capabilities and Services."
 
  COMPETITION. The electronic interconnect industry, which includes contract
manufacturing, is highly fragmented and is characterized by intense
competition. Altron competes in the technologically advanced segment of the
electronic interconnect industry, which is also highly competitive but is less
fragmented than the industry as a whole. The Company competes against numerous
domestic electronic interconnect product manufacturers. In addition, current
and prospective customers continually evaluate the merits of manufacturing
products internally and will from time to time offer manufacturing services to
third parties in order to utilize excess capacity. Certain of the Company's
competitors have substantially greater manufacturing, financial and marketing
resources than the Company. The Company may be operating at a cost disadvantage
compared to manufacturers who have greater direct buying power with component
suppliers or who have lower cost structures. During downturns in the
electronics industry, OEMs may become more price sensitive.
 
  The Company believes that the principal competitive factors in the electronic
interconnect industry are quality, service, technology, manufacturing
capability, regional access, price, reliability, timeliness and flexibility.
There can be no assurance that competition from existing or potential
competitors will not have a material adverse effect on the Company's results of
operations.
 
  The introduction of lower priced competitive products or significant price
reductions by the Company's competitors could result in price reductions that
would adversely affect the Company's results of operations, as would the
introduction of new technologies which would render the Company's existing
electronic interconnect technology less competitive or obsolete.
   
  CUSTOMER CONCENTRATION. For the year ended December 31, 1994 and the quarter
ended April 1, 1995, one of the Company's customers, Motorola, Inc., accounted
for approximately 13% and 17%, respectively of the Company's revenues. In
addition, in the aggregate the Company's twelve largest customers accounted for
approximately 57% and 67%, respectively, of the Company's revenues for such
periods. The loss of, or a significant curtailment of purchases by, any one or
more of these customers would have a material adverse effect on the Company's
results of operations. The Company anticipates that a significant portion of
its sales will continue to be concentrated in a small number of customers. See
"Business--Customers and Markets."     
 
  MANAGEMENT OF GROWTH. Altron has grown rapidly in recent years, including its
rapid expansion into the value added contract manufacturing business. A
continuing period of rapid growth, including geographic expansion, could place
a significant strain on the Company's management, operations and other
resources. The Company's ability to manage its growth will require it to
continue to invest in its operations, including its financial and management
information systems, and to retain, motivate and effectively manage its
employees. If the Company's management is unable to manage growth effectively,
the quality of the Company's services and products, its ability to retain key
personnel and its results of operations could be materially and adversely
affected. See "Business--Employees" and "Management."
 
  DEPENDENCE ON KEY PERSONNEL. The Company is highly dependent on its executive
officers and certain other key personnel, many of whom could be difficult to
replace. If the Company were to lose the services of certain of these people,
the Company's operating results could be adversely affected. In addition,
continued
 
                                       6
<PAGE>
 
growth and expansion of the Company's value added contract manufacturing
business and development of the Company will require that, despite significant
competition, it attract, motivate, and retain additional skilled and
experienced personnel. There can be no assurance that the Company will be able
to attract, motivate and retain personnel with the skills and experience needed
to successfully manage the Company's business and operations. See "Business--
Employees" and "Management."
 
  AVAILABILITY OF COMPONENTS. Electronic components used by Altron in producing
backplanes, surface mount assemblies and total systems are purchased by Altron
and, in certain circumstances, Altron may be required to bear the risk of
component price fluctuations. In addition, shortages of certain types of
electronic components have occurred in the past and may occur in the future.
Component shortages or price fluctuations could have an adverse effect on the
Company's backplane, surface mount assembly and total systems business, thereby
adversely affecting the Company's results of operations. To date, component
price fluctuations or shortages have not materially affected the Company. To
the extent that the Company's backplane, surface mount assembly and total
systems business expands as a percentage of the Company's net sales, component
shortages and price fluctuations would adversely affect the Company's results
of operations to a greater extent. A component for a major OEM contract is
obtained from a single source. An interruption or loss of this component supply
could have a material adverse effect on the Company's business and results of
operations. See "Business--Manufacturing Capabilities and Services--Materials
Procurement and Handling."
 
  ENVIRONMENTAL COMPLIANCE. Proper disposal of the metals and chemicals used in
the manufacturing process is a major consideration for interconnect product
manufacturers. Although the Company believes that its facilities are currently
in substantial compliance with applicable environmental laws, and although the
Company monitors its operations to avoid violations arising from human error or
equipment failures, there can be no assurance that violations will not occur.
In the event of a future violation of environmental laws, the Company could be
held liable for damages and for the costs of remedial actions and could also be
subject to revocation of its effluent discharge permits. Any such revocation
could require the Company to cease or limit production at its principal
facility, thereby having an adverse impact on the Company's operations. Altron
is also subject to environmental laws relating to the storage, use and disposal
of chemicals, solid waste and other hazardous materials, as well as air quality
regulations. Environmental laws could become more stringent over time, imposing
greater compliance costs and increasing risks and penalties associated with a
violation. See "Business--Environmental Quality."
 
  POSSIBLE VOLATILITY OF STOCK PRICE. The price of the Company's Common Stock
historically has experienced significant volatility due to fluctuations in
revenue and earnings and other factors relating to the Company's operations, as
well as the market's changing expectations for the Company's growth, overall
equity market conditions and other factors unrelated to the Company's
operations. Such fluctuations are expected to continue. In addition, stock
markets have experienced extreme price volatility in recent years, which has
had a substantial effect on the market price for securities issued by many
technology companies, often for reasons unrelated to the operating performance
of the specific companies. These broad market fluctuations may adversely affect
the price of the Company's Common Stock. See "Price Range of Common Stock."
 
  CONTROL BY FOUNDER'S FAMILY. After giving effect to the sale of the shares of
Common Stock offered hereby, Samuel Altschuler, members of his immediate family
in various capacities and certain trusts for the benefit of Mr. Altschuler and
members of his immediate family will own approximately 13.1% of the issued and
outstanding Common Stock of the Company (12.8% assuming the Underwriters' over-
allotment option is exercised in full), and will have the ability to exert
significant influence over the Company's corporate governance and over the
composition of the Company's Board of Directors. See "Principal and Selling
Stockholders."
 
  EFFECT OF CERTAIN CHARTER PROVISIONS, ANTI-TAKEOVER EFFECTS OF CHARTER,
BYLAWS AND MASSACHUSETTS LAW. The Board of Directors has the authority to issue
up to 1,000,000 shares of Preferred Stock and to determine the price, rights,
preferences, privileges and restrictions, including voting rights, of those
shares
 
                                       7
<PAGE>
 
without any further vote or action by the shareholders. The rights of the
holders of the Common Stock will be subject to, and may be adversely affected
by, the rights of the holders of any Preferred Stock that may be issued in the
future. The issuance of Preferred Stock, while providing desirable flexibility
in connection with possible acquisitions and other corporate purposes, could
have the effect of making it more difficult for a third party to acquire a
majority of the outstanding voting stock of the Company. The Company has no
present plans to issue shares of Preferred Stock. Further, certain provisions
of Massachusetts law could make more difficult a merger, tender offer or proxy
contest involving the Company. See "Description of Capital Stock."

                                USE OF PROCEEDS
   
  The net proceeds to the Company from the sale of the 1,100,000 shares of
Common Stock offered by the Company hereby are estimated to be $16,856,000 (or
approximately $19,656,000 assuming the Underwriters' over-allotment option is
exercised in full), at an assumed initial public offering price of $16.50 per
share (the last reported sales price of the Common Stock on May 10, 1995) and
after deducting the underwriting discounts and commissions and estimated
offering expenses payable by the Company. The Company expects to use the net
proceeds of this offering for working capital requirements and other general
corporate purposes. The Company may use a portion of the net proceeds of this
offering to acquire businesses, products or technologies complimentary to the
Company's business. Although Altron has from time to time engaged in
discussions with respect to possible acquisitions, it has no present
understandings, commitments or agreements, nor is it engaged in any discussions
or negotiations, with respect to any such transaction. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Liquidity and Capital Resources."     
 
  The Company will not receive any proceeds from the sale of the shares of
Common Stock by the Selling Stockholder. See "Principal and Selling
Stockholders."

Company believes that the number of beneficial holders was approximately 4,500,
based on information supplied by the Company's Transfer Agent.     
 
                                DIVIDEND POLICY
 
  The Company has never declared or paid cash dividends on shares of its Common
Stock and does not expect to declare or pay cash dividends on its Common Stock
in the foreseeable future. The Company intends to retain all of its available
funds for the operation and expansion of its business. Any future declaration
and payment of dividends will be subject to the discretion of the Board of
Directors, will be subject to applicable law and will depend upon the Company's
results of operations, earnings, financial condition, contractual limitations,
cash requirements, future prospects and other factors deemed relevant by the
Company's Board of Directors.

RESULTS OF OPERATIONS
   
THREE MONTHS ENDED APRIL 1, 1995 COMPARED TO THREE MONTHS ENDED APRIL 2, 1994
       
  Net sales for the first quarter of 1995 increased 42% to $32.7 million from
net sales of $23.0 million for the same quarter of 1994. The increase was
primarily the result of increased shipments to the Company's major customers in
the communications and computer segments of the electronics industry. The
Company's largest customer in each of the first quarters of 1995 and 1994 was
Motorola, Inc., which accounted for 17% and 14% of net sales, respectively.
       
  Value added contract manufacturing sales for the first quarter of 1995
increased 77% to $23.9 million or approximately 73% of net sales, compared to
$13.5 million or 59% of net sales in the first quarter of 1994. Of the $10.4
million increase in value added contract manufacturing sales, $5.2 million is
attributable to Altron Systems Corporation. Printed circuit board sales for the
first quarter of 1995 were $8.8 million or approximately 27% of net sales,
compared to $9.5 million or 41% of net sales in the first quarter of 1994.     
   
  Gross profit for the first quarter of 1995 increased 45% to $7.4 million from
$5.1 million in 1994. Gross margin as a percentage of net sales for 1995
increased to 22.7% as compared to 22.2% in 1994. The improvement in the
Company's gross margin resulted primarily from better absorption of fixed costs
due to the higher volume of shipments and was also due to increased
manufacturing efficiencies resulting from productivity and product yield
improvements.     
 
 
                                       12
<PAGE>
 
   
  Selling, general and administrative expenses increased to $2.6 million in the
first quarter of 1995 from $2.0 million for the same period a year ago. The
increase was due primarily to the added selling, general and administrative
expenses attributable to Altron Systems Corporation. Selling, general and
administrative expenses as a percentage of net sales decreased to 7.9% in the
first quarter of 1995 from 8.5% for the same quarter of 1994. The decline in
selling, general and administrative expenses as a percentage of net sales was
principally the result of higher net sales.     
   
  Other income increased $112,000 in the first quarter of 1995 as compared to
the first quarter of 1994. This increase was principally due to increased
interest income which resulted from higher rates of return earned on
investments and higher cash balances available for investment. Interest expense
was $45,000 lower in the first quarter of 1995 than 1994 as a result of reduced
outstanding borrowings and higher capitalized interest.     
 
FISCAL 1994 COMPARED TO FISCAL 1993
 
  Net sales for 1994 increased 25% to $104.2 million from net sales of $83.4
million for 1993. The increase was primarily the result of increased shipments
to the Company's largest customers in the data communications,
telecommunications and computer segments of the electronics industry, as well
as shipments to new customers in these industries. Improvement in general
economic conditions in the electronics industry has resulted in overall growth
for the Company's major customers in these industries. Data communications and
telecommunications customers accounted for approximately 54% of net sales in
each of 1994 and 1993. The Company's largest customer in each of 1994 and 1993
was Motorola, Inc., which accounted for approximately 13% of net sales in each
year.
 
  Value added contract manufacturing sales for 1994 increased 37% to $63.1
million or approximately 61% of net sales, compared to 1993 value added
contract manufacturing sales of $46.1 million or 55% of net sales. Of the $17.0
million increase, $5.9 million is attributable to the Astrio Acquisition.
Printed circuit board sales for 1994 increased 10% to $41.1 million or
approximately 39% of net sales, compared to 1993 printed circuit board sales of
$37.3 million or 45% of net sales. Although the printed circuit board business
will continue to be an important part of the Company's operations, management
believes that printed circuit board sales growth will not keep pace with the
sales growth anticipated in the value added contract manufacturing business for
the foreseeable future.
 
  Gross profit for 1994 increased 41% to $23.0 million from $16.4 million in
1993. Gross margin as a percentage of net sales for 1994 increased to 22.1% as
compared to 19.6% in 1993. The improvement in the Company's gross margin was
primarily a result of better absorption of fixed costs due to higher shipment
levels, and was also due to manufacturing efficiencies gained through
productivity and product yield improvements resulting from additional automated
manufacturing systems and processes. Although there can be no assurance that
the Company can maintain its current gross margin, management expects to focus
on market niches and product mix where there is less competitive pricing
pressure and to continue to improve productivity, yields and utilization.
 
  Selling, general and administrative expenses increased 18% to $8.6 million in
1994 from $7.3 million in 1993. Selling, general and administrative expenses as
a percentage of net sales decreased to 8.3% in 1994 from 8.8% in 1993. The
increase of $1.3 million in 1994 over 1993 was primarily due to added selling,
general and administrative expenses attributable to the Astrio operations since
the acquisition. The decline in selling, general and administrative expenses as
a percentage of net sales was principally the result of higher net sales
combined with management's ability to control expenses.
 
  Other income for 1994 increased $152,000 to $261,000 from other income of
$109,000 in 1993. This increase was principally due to increased interest
income which resulted from higher rates of return earned on investments and
higher cash balances available for investment. Interest expense for 1994
decreased to $574,000 from $582,000 in 1993. This decrease resulted from a
reduced mortgage interest rate which was partially offset by higher term loan
borrowings.
 
  The Company's effective tax rate in 1994 and 1993 reflects a provision of 40%
of pretax income.

FISCAL 1993 COMPARED TO FISCAL 1992
 
  Net sales for 1993 increased 22% to $83.4 million from net sales of $68.2
million in 1992. This increase was primarily the result of a higher volume of
shipments to existing customers and shipments to major new customers in the
data communications and telecommunications segments of the electronics
industry. Value added contract manufacturing sales for 1993 increased 21% to
$46.1 million or 55% of net sales, compared to 1992 value added contract
manufacturing sales of $38.1 million or 56% of net sales. Printed circuit board
sales for 1993 increased 24% to $37.3 million or 45% of net sales, compared to
1992 printed circuit board sales of $30.1 million or 44% of net sales. During
1993, the Company continued to experience pricing pressures from excess
capacity in the industry.
 
  Gross profit for 1993 increased 71% to $16.4 million from $9.6 million in
1992. Gross margin as a percentage of net sales for 1993 increased to 19.6% as
compared to 14.1% in 1992. The improvement in the Company's gross margin was
due to a higher volume of shipments, product mix, recovery of fixed costs over
higher volume and improvements in operating efficiencies resulting primarily
from productivity and yield improvements. These increases more than offset the
lower pricing which resulted from excess capacity in the industry.
 
  Selling, general and administrative expenses increased 4% to $7.3 million in
1993 from $7.0 million in 1992. Selling, general and administrative expenses as
a percentage of net sales decreased to 8.8% in 1993 from 10.3% in 1992. The
increase of $282,000 in 1993 over 1992 was due primarily to higher sales
commission costs on increased commissionable sales made by independent sales
representatives. The improvement in selling, general and administrative
expenses as a percentage of net sales was principally the result of higher net
sales.
   
  Other income for 1993 was $109,000 as compared to $108,000 for 1992. Interest
expense for 1993 decreased to $582,000 from $613,000 in 1992. This decrease
resulted from a reduced mortgage interest rate, lower borrowings under the line
of credit and higher interest capitalized, which were partially offset by
higher term loan borrowings.     
 
  The Company's effective tax rate in 1993 and 1992 reflects a provision of 40%
of pretax income.

LIQUIDITY AND CAPITAL RESOURCES
   
  During the first quarter of 1995 and the year 1994 the Company funded its
growth primarily from cash generated from operations. These funds were
sufficient to meet increased working capital needs and capital expenditures of
approximately $2.3 million in the first quarter of 1995 and $7.0 million in
1994. In addition, in 1994 the Company funded the Astrio Acquisition which
utilized $3.0 million in cash.     
   
  At April 1, 1995, the Company had working capital of $27.7 million compared
to working capital of $24.5 million at December 31, 1994. Cash and cash
equivalents and short term investments at April 1, 1995 were $11.2 million
compared to $10.3 million at December 31, 1994.     
   
  At April 1, 1995 and December 31, 1994, the Company had a $5.0 million
unsecured line of credit with its bank, all of which was available.     
   
  On February 10, 1995, the Board of Directors adopted a resolution to increase
the authorized shares of Common Stock outstanding from 10,000,000 shares to
30,000,000 shares with a par value of $.05 per share. The stockholders approved
the increase at a special meeting held on March 31, 1995.     
   
  The Company believes that its existing bank credit and working capital,
together with cash generated from operations and the net proceeds of this
offering, will be sufficient to satisfy anticipated sales growth and investment
in manufacturing facilities and equipment through 1996. The Company had
commitments for approximately $0.7 million of capital expenditures as of April
1, 1995 and $1.5 million at December 31, 1994. Management anticipates that
capital expenditures in 1995 will approximate 1994 capital expenditures.

                                    BUSINESS
 
  Altron is a leading contract manufacturer of interconnect products used in
advanced electronic equipment. The Company manufactures complex products in the
mid-volume sector of the electronic interconnect industry. Altron's products
generally require greater engineering and manufacturing expertise than mass-
produced, less complex products. The Company manufactures custom-designed
backplanes, surface mount assemblies and total systems, as well as multilayer,
high density printed circuit boards. Altron works closely with its customers
from the early stages of product design and development. The Company provides
original design, engineering prototype, preproduction and volume production
capabilities.
 
  Altron believes its capabilities both in manufacturing multilayer, high
density printed circuit boards and in providing value added contract
manufacturing services advantageously position the Company to serve high growth
OEMs in the rapidly changing electronics markets. Altron's OEM customers
include a diversified base of manufacturers in the telecommunications, data
communications, computer, industrial and medical systems segments of the
electronics industry, such as AT&T Corp., Cabletron Systems, Inc., Cascade
Communications Corp., Cisco Systems, Inc., Data General Corporation, EMC
Corporation, General Datacomm Industries, Inc., General Electric Company,
Hewlett-Packard Company, Motorola, Inc., Pyramid Technology Corporation,
Siemens Rolm Communications, Inc., Silicon Graphics, Inc., and Stratacom, Inc.
   
  Altron's strategy is to continue to use its well established high technology
printed circuit board manufacturing and engineering capabilities to further
expand into the rapidly growing contract manufacturing business, providing
products and services including backplanes, surface mount assemblies, power
supplies and total systems. Key elements of this strategy include providing its
customers with the highest levels of quality, superior service and leading edge
technology. In fiscal 1994, approximately 61% of Altron's net sales were
attributable to value added contract manufacturing, with the remaining 39% of
net sales attributable to printed circuit board manufacturing. Value added
contract manufacturing sales for the first quarter of 1995 were 73% of net
sales, and printed circuit board manufacturing sales were 27% of net sales.
    
ELECTRONIC INTERCONNECT INDUSTRY OVERVIEW
 
  Multilayer, High Density Printed Circuit Boards. According to The Institute
for Interconnecting and Packaging Electronic Circuits ("IPC"), the United
States printed circuit board market was approximately $6 billion in 1994, of
which approximately $4.9 billion was attributable to independent manufacturers
like Altron. IPC's data also shows that this market grew approximately 10% in
1994, with multilayer, high density printed circuit boards, the fastest growing
segment, accounting for approximately 62% of the 1994 market. IPC estimates
that the percentage of the printed circuit board market available to
independent printed circuit board manufacturers, such as Altron, has increased
from 66% to 82% since 1991.
 
  Value Added Contract Manufacturing. According to IPC, the United States value
added contract manufacturing market was approximately $9.4 billion in 1994 and
is growing about 20% per year. Based on industry data, the Company believes
that OEMs are increasingly relying upon independent manufacturers of complex
electronic interconnect products, such as Altron, rather than on in-house
("captive") production. OEMs which have discontinued or curtailed domestic
captive printed circuit board or backplane production since 1990 include AT&T
Corp., Data General Corporation, Digital Equipment Corporation, General
Electric Company, GTE Corporation, Hewlett-Packard Company, Northern Telecomm
Limited, Raytheon Company, Unisys Corporation, and Xerox Corporation. Altron
believes that the current trend towards increased reliance by OEMs on
independent manufacturers reflects the OEMs' recognition that, for complex
electronic interconnect products, independent manufacturers can provide greater
specialization, expertise, responsiveness and flexibility and can offer shorter
delivery cycles than can be achieved by internal production.

  Other factors which lead OEMs to utilize contract manufacturers include:
 
   Reduced Time-to-Market. Due to intense competitive pressures in the
   electronics industry, OEMs are faced with increasingly shorter product
   life-cycles and therefore have a growing need to reduce the time required
   to bring a product to market. OEMs can reduce their time to market by
   using a contract manufacturer's established manufacturing expertise and
   infrastructure.
 
   Reduced Capital Investment Requirements. As electronic products have
   become more technologically advanced, the manufacturing process has
   become increasingly sophisticated and automated, requiring a greater
   level of investment in capital equipment. By using contract
   manufacturers, OEMs can reduce their overall capital equipment
   requirements while maintaining access to advanced manufacturing
   facilities.
 
   Focused Resources. Because the electronics industry is experiencing
   greater levels of competition and rapid technological change, many OEMs
   increasingly are seeking to focus their resources on activities and
   technologies in which they add the greatest value. By offering
   comprehensive electronic assembly and turnkey manufacturing services,
   contract manufacturers allow OEMs to focus on core technologies and
   activities such as product development, marketing and distribution.
 
   Access to Leading Manufacturing Technology. Electronic interconnect
   products and electronic interconnect product manufacturing technology
   have become increasingly sophisticated and complex, making it difficult
   for OEMs to maintain the necessary technological expertise in process
   development and control. OEMs are motivated to work with a contract
   manufacturer in order to gain access to the contract manufacturer's
   process expertise and manufacturing know-how.
 
   Improved Inventory Management and Purchasing Power. Electronics industry
   OEMs are faced with increasing difficulties in planning, procuring and
   managing their inventories efficiently due to frequent design changes,
   short product life-cycles, large investments in electronic components,
   component price fluctuations and the need to achieve economies of scale
   in materials procurement. OEMs can reduce production costs by using a
   contract manufacturer's volume procurement capabilities. By utilizing a
   contract manufacturer's expertise in inventory management, OEMs can
   better manage inventory costs and increase their return on assets.
 
BUSINESS STRATEGY
 
  In response to the foregoing industry trends, Altron has transitioned its
business from primarily supplying printed circuit boards to producing
sophisticated value added electronic interconnect products.
 
  Altron's business strategy encompasses several elements:
 
  . Focus on quality. The Altron team strives to insure the highest levels of
    quality control in all phases of its operations, as quality is a critical
    competitive factor in the electronic interconnect market. The Company
    strives for continuous improvement of its processes and has adopted a
    number of quality improvement and measurement techniques to improve its
    performance. Altron's two principal plants are ISO 9002 registered.
 
  . Provide service oriented manufacturing. The Company manufactures almost
    all of the printed circuit boards used in its total systems, surface
    mount assemblies and custom designed backplanes in order to maintain
    control over costs, quality and timely delivery of its products. This
    vertical integration also allows the Company to provide a broader range
    of assembly services, including prototype and high technology products.
 
  . Maintain technology leadership. Altron seeks to deliver advanced
    manufacturing and test engineering, responsive materials management, and
    technologically advanced, flexible and service-oriented manufacturing for
    the complex, leading-edge products of its OEM customers throughout the
    full product life cycle.
 
                                       17
<PAGE>
 
  . Target high value added electronic interconnect products. Altron focuses
    on leading manufacturers of advanced electronic equipment who generally
    require custom-designed, more complex interconnect products and short
    lead-time manufacturing services such as quick turn multilayer printed
    circuit boards, backplanes and surface mount assemblies and in-house
    power supply and total systems design. By focusing on such customer
    needs, Altron has been able to achieve higher margins than many other
    participants in the electronic interconnect industry.
 
  . Maintain a diversified customer base. Altron services a diversified
   customer base spread over a variety of growing industry segments,
   including more than 100 customers in the telecommunications, data
   communications, computer, industrial and medical systems segments of the
   electronics industry. During fiscal 1994, in aggregate Altron's twelve
   largest customers accounted for approximately 57% of the Company's net
   sales.
 
  . Pursue a "partnership" approach with customers. Altron seeks to establish
   "partnerships" with its customers by involving Altron engineers and staff
   in the early design stages of its customers' product development, and by
   providing quick-turnaround manufacturing services and just-in-time, kanban
   and dock-to-stock delivery. Through this approach, Altron seeks to forge
   lasting customer relationships across a number of products and through
   multiple product generations.
 
PRODUCTS AND SERVICES
 
  Altron produces total systems, surface mount assemblies, custom designed
backplanes and multilayer printed circuit boards that are used in the
manufacture of sophisticated electronic equipment. For fiscal 1994, Altron's
sales of value added contract manufacturing products such as total systems,
surface mount assemblies and custom designed backplanes grew 37% and accounted
for approximately 61% of total sales. For fiscal 1994, Altron's sales of
printed circuit boards grew approximately 10% and accounted for approximately
39% of total sales. Approximately 85% of Altron's printed circuit board sales
in fiscal 1994 were sales of multilayer, high density printed circuit boards.
 
  Total systems include printed circuit board assemblies, backplanes, card
racks, and power supplies that are enclosed in housings, which are usually
fabricated from steel or aluminum. Altron has developed a highly sophisticated
mechanical design capability to provide its customers with design services.
This capability allows Altron to establish a close partnership with its
customers and gives Altron visibility for potential future customer
requirements.
 
  Custom designed backplanes are assemblies of stamped and plated pins, plastic
housings and other components on multilayer or two-sided printed circuit
boards. Backplanes are used in electronic systems to distribute power and
ground, and to connect printed circuit boards which plug into the backplane
with other printed circuit boards, power supplies, and other circuit elements.
They also are used to transfer information into and out of the system. As
semiconductor speeds have increased and design requirements have become more
stringent, backplane complexity has increased significantly, often requiring
the use of large multilayer printed circuit boards of six or more layers. The
Company manufactures backplanes with up to 32 layers, .300 inches thick, and 2
feet by 3 feet in size. Altron has recently added a complete fine-pitch surface
mount assembly operation to its backplane assembly capabilities, and also uses
press-fit technologies in backplane assembly.
 
  Surface mount assembly is a largely automated advanced interconnect
technology that involves placing semiconductor components directly on the
surface of both sides of a printed circuit board. This surface mount technology
("SMT") allows the leads on integrated circuits and other electronic components
to be soldered to the surface of the backplane assembly or printed circuit
board rather than being inserted into holes, thereby accommodating a
substantially higher number of leads than can be accommodated with less
sophisticated pin-through-hole technology. More leads permit the printed
circuit board to interconnect a greater density of components, which permits a
reduction in the size of the backplane assembly or printed circuit board.
 
                                       18
<PAGE>
 
Additionally, SMT allows components to be placed on both sides of the printed
circuit board, thereby permitting even greater density.
 
  Multilayer printed circuit boards consist of three or more layers of a
printed circuit board laminated together and interconnected by plated-through
holes. Printed circuit boards consist of metallic interconnecting paths on a
non-conductive material, typically laminated epoxy glass. Holes drilled in the
laminate and plated through with conductive material from one surface to
another, called plated-through holes, are used to receive component leads and
to interconnect the circuit layers. Multilayer boards increase packaging
density, improve power and ground distribution, and permit the use of higher
speed circuitry. The development of electronic components with increased speed,
higher performance and smaller size has stimulated a demand for multilayer
printed circuit boards, as they provide increased reliability, density and
complexity. Since even the most sophisticated two-sided printed circuit boards
cannot meet the requirements of today's circuit designers for packaging
density, an increasing number of designs use multilayer technology.
 
MANUFACTURING CAPABILITIES AND SERVICES
 
  Altron seeks to establish "partnerships" with its customers by providing high
quality, responsive, flexible manufacturing capabilities and services which
include:
 
  Advanced Manufacturing Equipment. Altron's concentration on more complex
electronic interconnect products has necessitated a substantial capital
investment in advanced equipment and the continued introduction of new
manufacturing processes. Altron has established an engineering capability to
select and implement the latest manufacturing technology. For example, the fine
lead spacing or "pitch" in SMT requires an exacting printed circuit board
manufacturing and assembly process, and Altron has state-of-the-art surface
mount assembly operations in all three of its plants. The Company also uses
numerically controlled pin installation and high voltage electrical test
equipment in its backplane assembly manufacturing, and has developed a design
and manufacturing capability for controlled impedance multilayer printed
circuit boards and backplane assemblies. Altron's printed circuit board
manufacturing operations also require state-of-the-art equipment and processes,
and Altron has a computerized artwork generation system, numerically controlled
drillers and routers, automatic electroless deposition, dry film photo-imaging,
automatic gold plating, computerized electrical testing and automatic optical
inspection. In addition, Altron has seven SMT machines, as well as Hewlett-
Packard and GenRad Test Equipment, new Nitrogen blanket flow soldering
equipment, and two automatic axial lead assembly lines. All three of Altron's
plants are staffed with highly experienced SMT engineering and manufacturing
teams which provide cost effective, high quality, assembled printed circuit
boards, backplanes and total systems.
 
  Value Added Contract Manufacturing. Computer integrated manufacturing ("CIM")
services provided by Altron consist of developing manufacturing processes and
tooling and test sequences for new products from product designs received from
customers. In addition, Altron's interconnect products division provides design
and engineering services in the early stages of product development, thus
assuring that both mechanical and electrical considerations are integrated into
a total system approach to achieve a producible, high quality and cost
effective product. Altron also evaluates customer designs for manufacturability
and, when appropriate, recommends design changes to reduce manufacturing costs
or lead times or to increase manufacturing yields and the quality of finished
backplane assemblies and printed circuit boards.
 
  Quick-turnaround. Altron's quick-turnaround manufacturing capabilities allow
it to better serve the needs of its customers for quick response to their
product designs. Shorter customer product life cycles and the need to bring new
products to market quickly have created a demand for small quantities of
complex multilayer printed circuit boards delivered in relatively short periods
of time, typically from three to ten days. Sales of printed circuit boards
produced in this manner accounted for approximately 21% of the Company's
printed circuit board sales in fiscal 1994. After engineering of an
interconnect product is completed, Altron has the capability to manufacture
prototype or preproduction versions of such product on a quick-turnaround
basis. Altron expects that the demand for engineering and quick-turnaround
prototype and preproduction
 
                                       19
<PAGE>
 
manufacturing services will increase as OEMs' products become more complex and
as product life cycles shorten. The Company's continued success depends upon
its ability to respond to the evolving needs of customers in a timely manner.
 
  Multilayer Printed Circuit Board Manufacturing. Altron's ability to
manufacture printed circuit boards, including large, complex multilayer printed
circuit boards with close tolerance plated-through hole diameters and other
characteristics important to backplane applications, is one of the major
factors that has enabled it to become an important supplier of complex,
technologically advanced backplane assemblies and multilayer printed circuit
boards to the electronics industry. The Company began manufacturing multilayer
boards in 1979 and in fiscal 1994 multilayer sales constituted 85% of the
Company's printed circuit board revenues. Today Altron is capable of
efficiently producing commercial quantities of printed circuit boards with up
to thirty two layers and circuit track widths as narrow as four mils.
 
  The manufacture of complex multilayer interconnect products often requires
the use of sophisticated circuit interconnections between certain layers
(called "blind or buried vias") and adherence to strict electrical
characteristics to maintain consistent circuit transmission speeds (referred to
as "controlled impedance boards"). These technologies require very tight
lamination and etching tolerances and are especially critical for printed
circuit boards with ten or more layers. The Company specializes in multilayer
boards requiring controlled impedance, and has developed the ability to
manufacture large, thick multilayer backplane boards using Cyanate Ester and
GETEK base materials for ultra high speed applications. By concentrating on the
multilayer segment of the printed circuit board market, where quality,
technology and customer service are more important than in the market for less
complex boards, the Company faces less direct competition.
 
  The manufacture of printed circuit boards involves several steps including
dry film imaging, photoimageable soldermask processing, computer controlled
drilling and routing, automated plating and process controls and achievement of
controlled impedance. Manufacture of printed circuit boards used in backplane
assemblies requires specialized expertise and equipment because of the size of
the backplane relative to other printed circuit boards and the closer hole
diameter tolerances required for press-fit pin assembly. Multilayer
manufacturing, which involves placing multiple layers of electrical circuitry
within a single printed circuit board or backplane, expands the number of
circuits and components that can be contained on the interconnect product and
increases the operating speed of the system by reducing the distance that
electrical signals must travel. Increasing the density of the circuitry in each
layer is accomplished by reducing the width of the circuit tracks and placing
them closer together on the printed circuit board or backplane. Interconnect
products having narrow, closely spaced circuit tracks are known as "fine line"
products.
 
  Materials Procurement and Handling. Materials procurement and handling
services provided by Altron include planning, purchasing and warehousing of
electronic components and metal housings used in interconnect products. Altron
uses a variety of materials in the manufacture of its products, including
copper clad laminates, dry film photo resists, connectors, terminals and pins.
 
  The Company maintains more than one supply source wherever possible, however,
a component for a major OEM contract is obtained from a single source. An
interruption or loss of this component supply could have a material adverse
effect on the Company's business and results of operations.
 
  ISO 9002 Registration. Altron's Wilmington, Massachusetts plant and its
surface mount assembly operations in its Fremont, California plant are ISO 9002
registered. The Company is currently pursuing such registration for its other
operations. ISO 9002 registration, which is based on successful implementation
of quality assurance requirements and includes continuous examination of every
aspect of the Company's business and compliance audits conducted by an
independent quality assessor, provides for worldwide acceptance of Altron's
quality systems. Altron was one of the first companies in the electronic
interconnect industry to achieve ISO 9002 registration. This achievement has
been well received by Altron customers, as certain customers will only do
business with ISO 9002 registered companies.

  Altron seeks to serve a sufficiently large and varied group of customers to
avoid dependence on any one major customer or industry segment. For the year
ended December 31, 1994 and for the three months ended April 1, 1995, one of
the Company's customers, Motorola, Inc., accounted for approximately 13% and
17%, respectively, of the Company's revenues. In addition, in aggregate the
Company's twelve largest customers (including Motorola, Inc.) accounted for
approximately 57% and 67%, respectively, of the Company's revenues during such
periods. See "Risk Factors--Customer Concentration."     
 
 
                                       21
<PAGE>
 
  The Company markets its products and services through its marketing and
customer service organization of 39 employees, and utilizes 17 independent
sales representative organizations located in the major electronics market
areas in the United States.
   
  For the year ended December 31, 1994, the Company's U.S. sales by its sales
regions were approximately 46% eastern, 32% western and 19% central.
International sales totaled approximately 3% of the Company's 1994 sales.     
 
COMPETITION
 
  The electronic interconnect industry, which includes contract manufacturing,
is highly fragmented and is characterized by intense competition. Altron
competes in the technologically advanced segment of the electronic interconnect
industry, which is also highly competitive but is less fragmented than the
industry as a whole. The Company competes against numerous domestic electronic
interconnect product manufacturers. In addition, current and prospective
customers continually evaluate the merits of manufacturing products internally
and will from time to time offer manufacturing services to third parties in
order to utilize excess capacity. Certain of the Company's competitors have
substantially greater manufacturing, financial and marketing resources than the
Company. The Company may be operating at a cost disadvantage compared to
manufacturers who have greater direct buying power with component suppliers or
who have lower cost structures. During downturns in the electronics industry,
OEMs may become more price sensitive.
 
  The Company believes that the principal competitive factors in the electronic
interconnect industry are quality, service, technology, manufacturing
capability, regional access, price, reliability, timeliness and flexibility.
There can be no assurance that competition from existing or potential
competitors will not have a material adverse effect on the Company's results of
operations.
 
  The introduction of lower priced competitive products or significant price
reductions by the Company's competitors could result in price reductions that
would adversely affect the Company's results of operations, as would the
introduction of new technologies which would render existing electronic
interconnect technology less competitive or obsolete.
 
BACKLOG
   
  Altron's sales are made principally through purchase orders for current
needs. The Company's backlog at April 1, 1995 was approximately $36.3 million
compared to approximately $27.1 million at April 2, 1994, the majority of which
was scheduled to be shipped within 120 days. Variations in the size and
delivery schedules of purchase orders received by the Company, as well as
changes in customers' delivery requirements, may result in substantial
fluctuations in backlog from period to period; accordingly, the Company
believes that backlog cannot be considered a meaningful indicator of long-term
future financial results.     
 
EMPLOYEES
   
  The Company had 953 full-time employees as of April 1, 1995. The employees
are not represented by a union, and the Company believes its employee relations
to be satisfactory. A majority of Company management, officers and executives
have over five years of service with the Company.     
 
FACILITIES
 
  Altron operates a 185,000 square foot manufacturing plant in Wilmington,
Massachusetts which is approximately 15 miles north of Boston. The plant
produces multilayer printed circuit boards and interconnect products. Altron
believes that this plant is one of the largest independent facilities of its
kind in the United States. In 1994, Altron began leasing a 70,000 square foot
facility in Fremont, California to manufacture interconnect systems, surface
mount assemblies and backplanes for its West Coast customers. Also in 1994,
Altron leased a 30,000 square foot plant in Woburn, Massachusetts for the
design and manufacture of interconnect systems, surface mount assemblies and
power supplies. The Company believes that its existing facilities are adequate
for its current needs. See "--Environmental Quality."
 
 
                                       22
<PAGE>
 
ENVIRONMENTAL QUALITY
 
   Proper waste disposal is a major consideration for printed circuit board
manufacturers because metals and chemicals are used in the manufacturing
process. Water used in the printed circuit board manufacturing process must be
treated to remove metal particles and other contaminants before it can be
discharged into the municipal sanitary sewer system. Altron has an existing
waste treatment system at its Wilmington plant which enables it to comply with
governmental regulations relating to the protection of the environment and
accommodate anticipated future growth. The Company believes that continued
compliance with governmental requirements relating to protection of the
environment will not have a material adverse effect on the Company. See "Risk
Factors--Environmental Compliance."
 
  Altron has been advised that contamination resulting from activities of prior
owners of an adjacent property has migrated under the Company's manufacturing
plant in Wilmington, Massachusetts. The present owner of the adjacent property
has assumed responsibility for any remediation activities that may be required
and has agreed to indemnify and hold the Company harmless from liabilities and
expenses arising from any requirement that the contamination be remediated.
Although the Company believes that the present owner's assumption of
responsibility will result in no remediation costs to the Company from the
contamination, there can be no assurance that the Company will not be subject
to some costs regarding this matter.
 
LEGAL PROCEEDINGS
 
  To the Company's knowledge there are no pending legal proceedings which are
material to the Company to which it is a party or to which any of its property
is subject.

                          DESCRIPTION OF CAPITAL STOCK
 
COMMON AND PREFERRED STOCK
   
  The Company's authorized capital stock consists of 1,000,000 shares of
Preferred Stock, par value $1.00 per share, and 30,000,000 shares of Common
Stock, par value $.05 per share. The Preferred Stock is divisible into and
issuable in one or more series. The rights and preferences of the different
series may be established by the Board of Directors without further action by
the stockholders. The Board of Directors is authorized with respect to each
series to fix and determine, among other things, (i) its dividend rate, (ii)
its liquidation preference, (iii) whether or not such shares will be
convertible into, or exchangeable for, any other securities or property, and
(iv) whether or not such shares will have voting rights, and, if so, the
conditions under which such shares will vote as a separate class.     
 
  The Company believes that the Board of Directors' ability to issue Preferred
Stock on such a wide variety of terms will enable the Preferred Stock to be
used for important corporate purposes, such as financing acquisitions or
raising additional capital. However, were it inclined to do so, the Board could
issue all or part of the Preferred Stock with (among other things) substantial
voting power or advantageous conversion rights. The issuance of Preferred Stock
could have adverse effects upon the holders of Common Stock, including
restrictions on Common Stock dividends, dilution of the voting power of the
Common Stock and other adverse effects. Such stock could be issued to persons
deemed by the Board likely to support current management in a contest for
control of the Company, either as a precautionary measure or in response to a
specific takeover threat, without requiring further action on the part of the
holders of Common Stock. The Company has no current plans to issue Preferred
Stock for any purpose.
 
  The holders of Common Stock and Preferred Stock have the following relative
rights and preferences:
 
  Dividends. Holders of Common Stock are entitled to dividends only when and if
declared by the Board of Directors of the Company out of funds legally
available for the payment thereof. No cash payment or distribution may be made
to the holders of Common Stock until all accumulated dividends on any series of
Preferred Stock which may be issued have been declared and set apart for
payment, and no shares of capital stock may be repurchased at any time when
accrued dividends on any series of Preferred Stock which may be issued are in
arrears.
 
  Voting Rights. Holders of Common Stock are entitled to one vote per share at
any annual or special meeting of stockholders. Holders of any series of
Preferred Stock which may be issued will be entitled to the voting rights fixed
by the Board of Directors for such series. Voting rights are not cumulative, so
that the holders of a majority of the voting power of the Company could elect
all the Directors standing for election at any annual or special meeting of
stockholders, and the holders of the remaining shares may not be able to elect
any Director.
 
  Liquidation. Upon the dissolution of the Company or any distribution of its
assets, the holders of Common Stock are entitled to all assets of the Company
available for distribution to stockholders after the holders of any series of
Preferred Stock which may be issued have received the preferential amount fixed
by the Board of Directors for such shares.
 
  Other Rights. The holders of Common Stock have no preemptive rights to
purchase shares of stock of the Company. Shares of Common Stock are not subject
to any redemption provisions and are not convertible into any other securities
or property. All outstanding shares of Common Stock are fully-paid and non-
assessable and the shares of Common Stock offered by the Company in the
offering, when issued, will be fully-paid and non-assessable.
 
  Transfer Agent. The transfer agent for the Common Stock is State Street Bank
and Trust Company, Boston, Massachusetts.

CERTAIN PROVISIONS OF MASSACHUSETTS LAW
 
  The Company is subject to the provisions of Chapter 110F of the Massachusetts
General Laws, an anti-takeover law. In general, this statute prohibits a
publicly held Massachusetts corporation with sufficient ties to Massachusetts
from engaging in a "business combination" with an "interested stockholder" for
a period of three years after the date of the transaction in which the person
becomes an interested stockholder, unless either (i) the interested stockholder
obtains the approval of the Board of Directors prior to becoming an interested
stockholder, (ii) the interested stockholder acquires 90% of the outstanding
voting stock of the corporation (excluding shares held by certain affiliates of
the corporation) at the time he becomes an interested stockholder or (iii) the
business combination is approved by both the Board of Directors and two-thirds
of the outstanding voting stock of the corporation (excluding shares held by
the interested stockholder). An "interested stockholder" is a person who,
together with affiliates and associates, owns (or at any time within the prior
three years did own) 5% or more of the corporation's voting stock. A "business
combination" includes mergers, stock and asset sales and other transactions
resulting in a financial benefit to the stockholder. The Company may at any
time amend its Articles of Organization or By-Laws to elect not to be governed
by Chapter 110F, by vote of the holders of a majority of its voting stock, but
such an amendment would not be effective for twelve months and would not apply
to a business combination with any person who became an interested stockholder
prior to the date of the amendment.
 
  The Company is also subject to the provisions of Chapter 110D of the
Massachusetts General Laws, entitled "Regulation of Control Share
Acquisitions." In general, this statute provides that any stockholder who
acquires 20% or more of the outstanding voting stock of a corporation subject
to this statute may not vote that stock unless the stockholders of the
corporation so authorize. In addition, Chapter 110D permits a corporation to
provide in its articles of organization or by-laws that the corporation may
redeem (for fair value) all the shares thereafter acquired in a control share
acquisition if voting rights for those shares were not authorized by the
stockholders or if no control share acquisition statement was delivered. The
Company's By-Laws include a provision which permits the Company to effect such
redemptions.
 
  Section 50A of Chapter 156B of the Massachusetts General Laws requires, among
other things, that publicly held Massachusetts corporations have classified
(staggered) boards of directors, unless those corporations elect to opt out of
the statute's coverage. By vote of the Board of Directors, the Company has
elected to opt out of this statute's coverage.

                        SHARES ELIGIBLE FOR FUTURE SALE
   
  Upon completion of this offering, the Company will have 9,575,063 issued and
outstanding shares of Common Stock (9,755,063 if the Underwriters' over-
allotment option is exercised in full). Of these shares, the 1,200,000 shares
of Common Stock offered hereby (1,380,000 if the Underwriters' over-allotment
option is exercised in full), will be freely tradeable without restriction or
further registration under the Securities Act of 1933, as amended (the
"Securities Act"). Of the 8,475,063 shares of Common Stock outstanding as of
May 9, 1995, 6,916,307 shares are freely tradeable and 1,558,756 shares (of
which 100,000 shares are being offered hereby) are held by directors, executive
officers and other persons, who may be deemed affiliates of the Company, and
may be sold after this offering pursuant to Rule 144, subject to the
contractual restrictions described below.     
   
  In general, under Rule 144 as currently in effect, any affiliate of the
Company or any person (or persons whose shares are aggregated in accordance
with the Rule) who has beneficially owned Restricted Securities for at least
two years would be entitled to sell within any three-month period a number of
shares that does not exceed the greater of 1% of the outstanding shares of
Common Stock (approximately 95,750 shares based upon the number of shares
outstanding after this offering) or the reported average weekly trading volume
in the over-the-counter market for the four weeks preceding the sale. Sales
under Rule 144 are also subject to certain manner of sale restrictions and
notice requirements and to the availability of current public information
concerning the Company. Persons who have not been affiliates of the Company for
at least three months and who have held their shares for more than three years
are entitled to sell Restricted Securities without regard to the volume, manner
of sale, notice and public information requirements of Rule 144.     
   
  The Company has registered, or is in the process of registering, the shares
of Common Stock subject to its stock option plans under the Securities Act.
Shares of Common Stock issued upon exercise of outstanding options under these
plans will generally be eligible for immediate resale in the public market. As
of May 9, 1995, options to purchase an aggregate of 1,100,025 shares were
outstanding under the Company's stock option plans, of which 285,125 were
exercisable as of May 9, 1995. Of the 285,125 shares subject to options
exercisable as of such date, 198,750 shares are subject to the Lock-Up
Agreements as defined below.     
   
  The Company has agreed that it will not, directly or indirectly, offer, sell,
offer to sell, contract to sell, grant any option to purchase or otherwise sell
or dispose (or announce any offer, sale, offer of sale, contract of sale, grant
of any option to purchase or other sale or disposition) of any shares of Common
Stock or other capital stock of the Company or any securities convertible into,
or exercisable or exchangeable for, any shares of Common Stock or other capital
stock of the Company (other than pursuant to the exercise of currently
outstanding stock options) for a period of 180 days after the date of this
Prospectus, without the prior written consent of Prudential Securities
Incorporated, on behalf of the Underwriters. In addition, the Selling
Stockholder, who will beneficially own approximately 1,256,650 shares
immediately upon completion of this offering, has agreed to such restrictions
for a period of 120 days after the date of this Prospectus, and the Company's
other directors and officers, who in the aggregate will beneficially own
approximately 867,731 shares immediately upon completion of this offering, have
agreed to such restrictions for a period of 90 days after the date of this
Prospectus (collectively the "Lock-Up Agreements"). Upon the expiration of the
Lock-Up Agreements, the shares subject thereto will be eligible for sale in the
public market, subject to the conditions and restrictions of Rule 144.     
 
  No prediction can be made as to the effect, if any, that market sales of
shares or the availability of shares for sale will have on the market price for
the Common Stock prevailing from time to time. Nevertheless, sales of
substantial amounts of the Common Stock of the Company in the public market
after the restrictions described above lapse could adversely affect the
prevailing market price and the ability of the Company to raise equity capital
in the future.

  The Company and the Selling Stockholder are obligated to sell, and the
Underwriters are obligated to purchase, all of the shares of Common Stock
offered hereby if any are purchased.
 
  The Underwriters, through their Representatives, have advised the Company and

  The Company has granted to the Underwriters an option, exercisable for 30
days from the date of this Prospectus, to purchase up to an aggregate of
180,000 additional shares of Common Stock at the initial public offering price,
less underwriting discounts and commissions, as set forth on the cover page of
this Prospectus. The Underwriters may exercise such option solely for the
purpose of covering any over-allotments incurred in the sale of the shares of
Common Stock offered hereby. To the extent such option is exercised, each
Underwriter will become obligated, subject to certain conditions, to purchase
approximately the same percentage of such additional shares as the number set
forth next to such Underwriters' name in the preceding table bears to
1,200,000.
 
  The Company and the Selling Stockholder have agreed to indemnify the several
Underwriters against or contribute to losses arising out of certain
liabilities, including liabilities under the Securities Act of 1933, as
amended.
 
  The Company has agreed that it will not, directly or indirectly, without the
prior written consent of Prudential Securities Incorporated, on behalf of the

Company substantially similar thereto or any other securities convertible into,
or exchangeable or exercisable for, any shares of Common Stock or other capital
stock of the Company for a period of 180 days after the date of this
Prospectus, other than pursuant to the exercise of currently outstanding stock
options . In addition, the Selling Stockholder has agreed to such restrictions
for a period of 120 days after the date of this Prospectus and the Company's
other directors and officers have agreed to such restrictions for a period of
90 days after the date of this Prospectus.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Altron Incorporated:
 
  We have audited the accompanying consolidated balance sheets of Altron
Incorporated (a Massachusetts corporation) and subsidiary as of January 1, 1994
and December 31, 1994 and the related consolidated income statements,
statements of stockholders' investment and cash flows for the years ended
January 2, 1993, January 1, 1994 and December 31, 1994. 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 Altron Incorporated and
subsidiary as of January 1, 1994 and December 31, 1994, and the results of
their operations and their cash flows for the years ended January 2, 1993,
January 1, 1994 and December 31, 1994 in conformity with generally accepted
accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               DECEMBER 31, 1994
                
             (INCLUDING DATA APPLICABLE TO UNAUDITED PERIODS)     
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 BUSINESS
 
  Altron Incorporated ("the Company") is a leading contract manufacturer of
interconnect products used in advanced electronic equipment. The Company
manufactures complex products in the mid-volume sector of the electronic
interconnect industry including custom-designed backplanes, surface mount
assemblies and total systems, as well as multilayer, high density printed
circuit boards. Altron's customers include a diversified base of manufacturers
in the telecommunications, data communications, computer, industrial and
medical systems segments of the electronics industry.
 
  On June 9, 1994, Altron Systems Corporation, a wholly-owned subsidiary,
completed the acquisition of Astrio Corporation, a manufacturer of complex
surface mount assemblies. The acquisition has been accounted for as a purchase,
and the results of operations have been included in the accompanying
consolidated income statements from the date of acquisition.
 
 FISCAL YEAR
 
  The Company's fiscal year ends on the Saturday closest to December 31. In the
financial statements, "1992" refers to the year ended January 2, 1993; "1993"
refers to the year ended January 1, 1994; and "1994" refers to the year ended
December 31, 1994. Operations for fiscal year 1992 include 53 weeks while all
other years presented include 52 weeks.
   
 INTERIM FINANCIAL STATEMENTS     
   
  In the opinion of management, these financial statements contain all
adjustments (consisting of normal recurring adjustments) which management
considers necessary for a fair presentation of the results for such periods.
The results of operations for the quarter ended April 1, 1995 are not
necessarily indicative of the results of operations for the full year.     
 
 PRINCIPLES OF CONSOLIDATION
 
  The accompanying consolidated financial statements include the accounts of
the Company and Altron Systems Corporation, its wholly owned subsidiary. All
significant intercompany balances and transactions have been eliminated in
consolidation.
 
 REVENUE RECOGNITION
 
  The Company recognizes product sales upon shipment.
 
 CASH AND CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS
 
  The Company considers all highly liquid investment instruments purchased with
a maturity of three months or less to be cash equivalents. Short-term
investments are carried at cost, which approximates market value, and have
maturities of less than one year.
 
 
  The Company adopted Statement of Financial Accounting Standards (SFAS) No.
115, "Accounting for Certain Investments in Debt and Equity Securities." This
statement addresses the accounting and reporting for investments in marketable
equity securities that have readily determinable fair values and for all
investments in debt securities.
 
  The Company classifies its investment in commercial paper and short-term
treasury bills as held-to-maturity given the Company's intent and ability to
hold the securities to maturity. In accordance with the statement, held-to-
maturity securities are carried at amortized cost.
 
  In October 1994, the Financial Accounting Standards Board issued SFAS No.
119, "Disclosure about Derivative Financial Instruments and Fair Value of
Financial Instruments", which is effective for fiscal years ending after
December 15, 1994. As of December 31, 1994, the Company had no financial
instruments requiring disclosure under SFAS No. 119.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
                               DECEMBER 31, 1994
 
                (INCLUDING DATA APPLICABLE TO UNAUDITED PERIODS)
 
 NET INCOME PER COMMON AND COMMON EQUIVALENT SHARE
 
  Net income per common and common equivalent share was computed based on the
weighted average number of common and common equivalent shares outstanding
during each year. Common equivalent shares include outstanding stock options.
Fully diluted net income per share has not been separately presented as it
would not be materially different from net income per share as presented.
 
(2) ACQUISITION
 
  On June 9, 1994, Altron Systems Corporation, a wholly owned subsidiary,
completed the acquisition of Astrio Corporation, a manufacturer of complex
surface-mount assemblies, for $4,685,000 consisting of $3,000,000 cash and
$1,685,000 in Altron's common stock (167,108 shares). In addition, $1,565,000
in liabilities were assumed and related acquisition costs of $64,000 were
incurred.
 
  The acquisition has been accounted for as a purchase, and the results of
operations of Altron Systems Corporation since June 9, 1994 have been included
in the accompanying consolidated income statements. The aggregate cost of the
acquisition exceeded the estimated fair value of the acquired net assets by
$4,154,000 which is being amortized on a straight-line basis over an estimated
useful life of 15 years. The allocation of the purchase price was based on the
fair value of the net assets acquired and is subject to adjustment. The Company
continually assesses whether a change in circumstances has occurred subsequent
to the acquisition that would indicate that the future useful life of the asset
(Costs in Excess of Net Assets of Acquired Company) should be revised. The
Company considers the future earnings potential of the original business in
assessing the recoverability of this asset.
 
  The following table presents selected financial information for the Company
and its subsidiary on a proforma basis, assuming the companies had been
combined as of January 3, 1993. The proforma results are not necessarily
indicative of the actual results or future results of operations that would
have occurred had the acquisition been made on January 3, 1993.

             (INCLUDING DATA APPLICABLE TO UNAUDITED PERIODS)     
  The tax effects of temporary differences included in other current assets as
of January 1, 1994 are $420,000 for inventory and receivables, $533,000 for
accruals, $72,000 for non-qualified stock options and $120,000 for other net
differences. The temporary differences as of December 31, 1994 are $555,000 for
inventory and receivables, $615,000 for accruals, $72,000 for non-qualified
stock options and $37,000 for other net differences.
 
  Deferred income taxes as of January 1, 1994 and December 31, 1994 are
$3,561,000 and $4,044,000, respectively, and resulted principally from the
difference between book and tax depreciation methods.
 
  For 1993 and 1994, the Company realized tax benefits of $1,265,000 and
$408,000, respectively, for disqualifying dispositions of stock options
exercised which are deemed compensation for tax purposes. For financial
reporting purposes, the benefit is accounted for as a credit to paid-in capital
rather than as a reduction of income tax expense.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Section 67 of Chapter 156B of the Massachusetts Business Corporation Law,
which is applicable to the Company, provides as follows:
 
  Indemnification of directors, officers, employees and other agents of a
corporation, and persons who serve at its request as directors, officers,
employees or other agents of another organization, or who serve at its request
in any capacity with respect to any employee benefit plan, may be provided by
it to whatever extent shall be specified in or authorized by (i) the articles
of organization or (ii) a by-law adopted by the stockholders or (iii) a vote
adopted by the holders of a majority of the shares of stock entitled to vote on
the election of directors. Except as the articles of organization or by-laws
otherwise require, indemnification of any persons referred to in the preceding
sentence who are not directors of the corporation may be provided by it to the
extent authorized by the directors. Such indemnification may include payment by
the corporation of expenses incurred in defending a civil or criminal action or
proceeding in advance of the final disposition of such action or proceeding,
upon receipt of an undertaking by the person indemnified to repay such payment
if he shall be adjudicated to be not entitled to indemnification under this
section which undertaking may be accepted without reference to the financial
ability of such person to make repayment. Any such indemnification may be
provided although the person to be indemnified is no longer an officer,
director, employee or agent of the corporation or of such other organization or
no longer serves with respect to any such employee benefit plan.
 
  No indemnification shall be provided for any person with respect to any
matter as to which he shall have been adjudicated in any proceeding not to have
acted in good faith in the reasonable belief that his action was in the best
interest of the corporation or to the extent that such matter relates to
service with respect to an employee benefit plan, in the best interests of the
participants or beneficiaries of such employee benefit plan.
 
  The absence of any express provision for indemnification shall not limit any
right of indemnification existing independently of this section.
 
  A corporation shall have power to purchase and maintain insurance on behalf
of any person who is or was a director, officer, employee or other agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or other agent of another organization or with
respect to any
 
                                      II-1
<PAGE>
 
employee benefit plan, against any liability incurred by him in any such
capacity, or arising out of his status as such, whether or not the corporation
would have the power to indemnify him against such liability.
 
  In addition, pursuant to its Articles of Organization and By-Laws, the
Company shall indemnify its directors and officers against expenses (including
judgments or amounts paid in settlement) incurred in any action, civil or
criminal, to which any such person is a party by reason of any alleged act or
failure to act in his capacity as such, except as to a matter as to which such
director or officer shall have been finally adjudged not to have acted in good
faith in the reasonable belief that his action was in the best interest of the
Company.

ITEM 17. UNDERTAKINGS.
 
  Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the issuer in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question of whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.
 
  The undersigned registrant hereby undertakes that:
 
    1. For the purpose of determining any liability under the Securities Act
  of 1933, the information omitted from the form of prospectus filed as part
  of this registration statement in reliance upon Rule 430A and contained in
  a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
  (4) or 497(h) under the Securities Act shall be deemed to be part of this
  registration statement as of the time it was declared effective.
 
    2. For purposes of determining any liability under the Securities Act of
  1933, each post-effective amendment that contains a form of prospectus
  shall be deemed to be a new registration statement relating to the
  securities offered therein, and the offering of such securities at that
  time shall be deemed to be the initial bona fide public offering thereof.

     2.  Representations and Warranties.
         ------------------------------

         (a)  The Company and the Selling Stockholder, jointly and severally,
represent and warrant to, and agree with, each of the several Underwriters that:

              (i)    The Company meets the requirements for use of Form S-3
   under the Securities Act of 1933, as amended (the "Act"). A registration
   statement on such Form (File No. 33-58287) with respect to the Securities,
   including a prospectus subject to completion, has been filed by the Company
   with the Securities and Exchange Commission (the "Commission") under the Act,
   and one or more amendments to such registration statement may have been so
   filed. After the execution of this Agreement, the Company will file with the
   Commission either (A) if such registration statement, as it may have been
   amended, has been declared by the Commission to be effective under the Act, a
   prospectus in the form most recently included in an amendment to such
   registration statement (or, if no such amendment shall have been filed, in
   such registration statement), with such changes or insertions as are required
   by Rule 430A under the Act or permitted by Rule 424(b) under the Act and as
   have been provided to and approved by the Representatives prior to the
   execution of this Agreement, or (B) if such registration statement, as it may
   have been amended, has not been declared by the Commission to be effective
   under the Act, an amendment to such registration statement, including a form
   of prospectus, a copy of which amendment has been furnished to and approved
   by the Representatives prior to the execution of this Agreement. As used in
   this Agreement, the term "Registration Statement" means such registration
   statement, as amended at the time when it was or is declared effective,
   including (1) all financial schedules and exhibits thereto, (2) all documents
   incorporated by reference therein filed under the Securities Exchange Act of
   1934, as amended (the "Exchange Act"), and (3) any information omitted
   therefrom pursuant to Rule 430A under the Act and included in the Prospectus
   (as hereinafter defined); the term "Preliminary Prospectus" means each
   prospectus subject to completion filed with such registration statement or
   any amendment thereto (including the prospectus subject to completion, if
   any, included in the Registration Statement or any amendment thereto at the
   time it was or is declared effective), including all documents incorporated
   by reference therein filed under the Exchange Act; and the term "Prospectus"
   means the prospectus first filed with the Commission pursuant to Rule 424(b)
   under the Act or, if no prospectus is required to be filed pursuant to said
   Rule 424(b), such term means the prospectus included in the Registration
   Statement, in either case including all documents incorporated by reference
   therein filed under the Exchange Act. Any reference in this Agreement to an
   "amendment or supplement" to any Preliminary Prospectus or the Prospectus or
   any "amendment" to any registration statement (including the Registration
   Statement) shall be deemed to include any document incorporated by reference
   therein that is filed with the Commission under the Exchange Act after the
   date of such Preliminary Prospectus, Prospectus or registration statement, as
   the case may be. For purposes of the preceding sentence, any reference to the
   "effective date" of an amendment to a registration statement shall, if such
   amendment is effected by means of the filing with the Commission under the
   Exchange Act of a document incorporated by reference in such registration
   statement, be deemed to refer to the date on which such document was so filed
   with the Commission .

              (ii)   The Commission has not issued any order preventing or
   suspending the use of any Preliminary Prospectus. When any Preliminary
   Prospectus and any amendment or supplement thereto was filed with the
   Commission, it (A) contained all statements required to be stated therein in
   accordance with, and complied in all material respects with the requirements
   of, the Act, the Exchange Act and the respective rules and regulations of
   Commission thereunder, and (B) did not include any untrue statement of a
   material fact or omit to state any material fact necessary in order to make
   the statements therein, in the light of the circumstances under which they
   were made, not misleading. When the Registration Statement or any amendment
   thereto was or is declared effective, it (A) contained or will contain all
   statements required to be stated therein in accordance with, and complied or
   will comply in all material respects with the requirements of, the Act, the
   Exchange Act and the respective rules and regulations of the Commission
   thereunder and (B) did not or will not include any untrue statement of a
   material fact or omit to state any material fact necessary to make the
   statements therein not misleading. When the Prospectus or any amendment or
   supplement thereto is filed with the Commission pursuant to Rule 424(b) (or,
   if the Prospectus or such amendment or supplement is not required to be so
   filed, when the Registration Statement or the amendment thereto containing
   such amendment or supplement to the Prospectus was or is declared effective),
   on the date when the Prospectus is otherwise amended or supplemented and on
   the Firm Closing Date and any Option Closing Date (both as hereinafter
   defined), the Prospectus, as amended or supplemented at any such time, (A)
   contained or will contain all statements required to be stated therein in
   accordance with, and complied or will comply in all material respects with
   the requirements of, the Act, the Exchange Act and the respective rules and
   regulations of the Commission thereunder and (B) did not or will not include
   any untrue statement of a material fact or omit to state any material fact
   necessary in order to make the statements therein, in the light of the
   circumstances under which they were made, not misleading. The foregoing
   provisions of this paragraph (ii) do not apply to statements or omissions
   made in any Preliminary Prospectus or any amendment thereto or supplement
   thereto, the Registration Statement or any amendment thereto or the
   Prospectus or any amendment or supplement thereto in reliance upon and in
   conformity with written information furnished to the Company by any
   Underwriter through the Representatives specifically for use therein.

              (iii)  The Company and each of its subsidiaries have been duly
   organized and are validly existing as corporations in good standing under the
   laws of their respective jurisdictions of incorporation and are duly
   qualified to transact business as foreign corporations and are in good
   standing under the laws of all other jurisdictions where the ownership or
   leasing of their respective properties or the conduct of their respective
   businesses requires such qualification, except where the failure to be so
   qualified does not amount to a material liability or disability to the
   Company and its subsidiaries, taken as a whole.

              (iv)   The Company and each of its subsidiaries have full power
   (corporate and other) to own or lease their respective properties and conduct
   their respective businesses as described in the Registration Statement and
   the Prospectus or, if the Prospectus is not in existence, the most recent
   Preliminary Prospectus; and the Company has full power (corporate and other)
   to enter into this Agreement and to carry out all the terms and provisions
   hereof to be carried out by it.

              (v)    The issued shares of capital stock of each of the Company's
   subsidiaries have been duly authorized and validly issued, are fully paid and
   nonassessable and are owned beneficially by the Company free and clear of any
   security interests, liens, encumbrances, equities or claims.

              (vi)   The Company has an authorized, issued and outstanding
   capitalization as set forth in the Prospectus or, if the Prospectus is not in
   existence, the most recent Preliminary Prospectus. All of the issued shares
   of capital stock of the Company have been duly authorized and validly issued
   and are fully paid and nonassessable. The Firm Securities and the Option
   Securities have been duly authorized and at the Firm Closing Date or the
   related Option Closing Date (as the case may be), after payment therefor in
   accordance herewith, will be validly issued, fully paid and nonassessable. No
   holders of outstanding shares of capital stock of the Company are entitled as
   such to any preemptive or other rights to subscribe for any of the
   Securities, and no holder of securities of the Company has any right which
   has not been fully exercised or waived to require the Company to register the
   offer or sale of any securities owned by such holder under the Act or to
   include such securities in the Registration Statement covering the public
   offering contemplated by this Agreement.

              (vii)  The capital stock of the Company conforms to the
   description thereof contained in the Prospectus or, if the Prospectus is not
   in existence, the most recent Preliminary Prospectus. Except as disclosed in
   the Prospectus (or, if the Prospectus is not in existence, the most recent
   Preliminary Prospectus), as of the date hereof there are no outstanding (A)
   securities or obligations of the Company or any of its subsidiaries
   convertible into or exchangeable for any capital stock of the Company or any
   such subsidiary, (B) warrants, rights or options to subscribe for or purchase
   from the Company or any such subsidiary any such capital stock or any such
   convertible or exchangeable securities or obligations, or (C) obligations of
   the Company or any such subsidiary to issue any shares of capital stock, any
   such convertible or exchangeable securities or obligations, or any such
   warrants, rights or options.
       
              (viii) The consolidated financial statements and schedules of the
   Company and its consolidated subsidiaries included in the Registration
   Statement and the Prospectus (or, if the Prospectus is not in existence, the
   most recent Preliminary Prospectus) fairly present the financial position of
   the Company and its consolidated subsidiaries and the results of operations
   and changes in financial condition as of the dates and periods therein
   specified. Such financial statements and schedules have been prepared in
   accordance with generally accepted accounting principles (except, in the case
   of unaudited interim financial statements, for normal recurring adjustments)
   consistently applied throughout the periods involved (except as otherwise
   noted therein). The selected financial data set forth under the caption
   "Selected Consolidated Financial Data" in the Prospectus (or, if the
   Prospectus is not in existence, the most recent Preliminary Prospectus),
   in the Company's Annual Report on Form 10-K for the fiscal year ended
   December 31, 1994, and in the Company's Quarterly Report on Form 10-Q for the
   fiscal quarter ended April 1, 1995 fairly present, on the basis stated in the
   Prospectus (or such Preliminary Prospectus), such Annual Report and such
   Quarterly Report, the information included therein.

   the Company or any of its subsidiaries is a party or to which the property of
   the Company or any of its subsidiaries is subject that are required to be
   described in the Registration Statement or the Prospectus and are not

   required to be described in, or to be filed as an exhibit to, any documents
   filed under the Exchange Act (or portions thereof), which are incorporated by
   reference in the Registration Statement, that are not described therein or

              (xii)  The issuance, offering and sale of the Securities to the
   Underwriters by the Company pursuant to this Agreement, the compliance by the
   Company with the other provisions of this Agreement and the consummation of
   the other transactions herein contemplated do not (A) require the consent,
   approval, authorization, registration or qualification of or with any
   governmental authority, except such as have been obtained, such as may be
   required by the National Association of Securities Dealers, Inc. or under
   state securities or blue sky laws and, if the registration statement filed
   with respect to the Securities (as amended) is not effective under the Act as
   of the time of execution hereof, such as may be required (and shall be
   obtained as provided in this Agreement) under the Act, or (B) conflict with
   or result in a breach or violation of any of the terms and provisions of, or
   constitute a default under, any indenture, mortgage, deed of trust, lease or
   other agreement or instrument to which the Company or any of its subsidiaries
   is a party or by which the Company or any of its subsidiaries or any of their
   respective properties are bound, or the charter documents or by-laws of the
   Company or any of its subsidiaries, or any statute or any judgment, decree,
   order, rule or regulation of any court or other governmental authority or any
   arbitrator applicable to the Company or any of its subsidiaries.

              (xiii) The Company has not, directly or indirectly, (A) taken any
   action designed to cause or to result in, or that has constituted or which
   might reasonably be expected to constitute, the stabilization or manipulation

   anyone any compensation for soliciting purchases of, the Securities or (2)
   paid or agreed to pay to any person any compensation for soliciting another
   to purchase any other securities of the Company (except for the sale of
   Securities by the Selling Stockholder under this Agreement).

              (xiv)  Subsequent to the respective dates as of which information
   is given in the Registration Statement and the Prospectus (or, if the
   Prospectus is not in existence, the most recent Preliminary Prospectus), (A)
   the Company and its subsidiaries have not incurred any material liability or
   obligation, direct or contingent, nor entered into any material transaction
   not in the ordinary course of business; (B) the Company has not purchased any
   of its outstanding capital stock, nor declared, paid or otherwise made any
   dividend or distribution of any kind of its capital stock; and (C) there has

              (xv)   The Company and each of its subsidiaries have good and
   marketable title in fee simple to all items of real property and marketable
   title to all personal property owned by each of them, in each case free and
   clear of any security interests, liens, encumbrances, equities, claims and

   value of such property and do not interfere with the use made or proposed to
   be made of such property by the Company or such subsidiary, and any real
   property and buildings held under lease by the Company or any such subsidiary
   are held under valid, subsisting and enforceable leases, with such exceptions
   as are not material and do not interfere with the use made or proposed to be

   each case except as described in or contemplated by the Prospectus (or, if
   the Prospectus is not in existence, the most recent Preliminary Prospectus).

              (xvi)  No labor dispute with the employees of the Company or any
   of its subsidiaries exists or is threatened or imminent that could result in
   a material adverse change in the condition (financial or otherwise), business
   prospects, net worth or results of operations of the Company and its
   subsidiaries, except as described in or contemplated by the Prospectus (or,
   if the Prospectus is not in existence, the most recent Preliminary

   subsidiary has received any notice of infringement of or conflict with
   asserted rights of any third party with respect to any of the foregoing
   which, singly or in the aggregate, if the subject of an unfavorable decision,

   insurers of recognized financial responsibility against such losses and risks
   and in such amounts as are prudent and customary in the businesses in which
   they are engaged; neither the Company nor any such subsidiary has any reason
   to believe that it will not be able to renew its existing insurance coverage
   as and when such coverage expires or to obtain similar coverage from similar
   insurers as may be necessary to continue its business at a cost that would
   not materially and adversely affect the condition (financial or otherwise),
   business prospects, net worth or results of operations of the Company and its
   subsidiaries, except as described in or contemplated by the Prospectus (or,
   if the Prospectus is not in existence, the most recent Preliminary

   authorizations and permits issued by the appropriate federal, state or
   foreign regulatory authorities necessary to conduct their respective
   businesses, except where the failure to possess any such certificate,
   authorization or permit, singly or in the aggregate, would not result in a
   material adverse change in the condition (financial or otherwise), business
   prospects, net worth or results of operations of the Company and its
   subsidiaries, and neither the Company nor any such subsidiary has received
   any notice of proceedings relating to the revocation or modification of any
   such certificate, authorization or permit which, singly or in the aggregate,

   a material adverse change in the condition (financial or otherwise), business
   prospects, net worth or results of operations of the Company and its
   subsidiaries, except as described in or contemplated by the Prospectus (or,
   if the Prospectus is not in existence, the most recent Preliminary
   Prospectus).

              (xxi)   The Company will conduct its operations in a manner that
   will not subject it to registration as an investment company under the
   Investment Company Act of 1940, as amended, and this transaction will not
   cause the Company to become an investment company subject to registration
   under such Act.

              (xxii)  The Company has filed all foreign, federal, state and
   local tax returns that are required to be filed or has requested extensions

   material adverse effect on the Company and its subsidiaries) and has paid all
   taxes required to be paid by it and any other assessment, fine or penalty
   levied against it, to the extent that any of the foregoing is due and
   payable, except for any such assessment, fine or penalty that is currently
   being 

                                       7
<PAGE>
 
   contested in good faith or as described in or contemplated by the Prospectus
   (or, if the Prospectus is not in existence, the most recent Preliminary
   Prospectus).

              (xxiii)  Neither the Company nor any of its subsidiaries is in
   violation of any federal or state law or regulation relating to occupational
   safety and health or to the storage, handling, or transportation of hazardous
   or toxic materials and the Company and its subsidiaries have received all
   permits, licenses or other approvals required of them under applicable
   federal and state occupational safety and health and environmental laws and
   regulations to conduct their respective businesses, and the Company and each
   such subsidiary is in compliance with all terms and conditions of any such
   permit, license or approval, except any such violation of law or regulation,
   failure to receive required permits, licenses or other approvals or failure
   to comply with the terms and conditions of such permits, licenses or
   approvals which would not, singly or in the aggregate, result in a material
   adverse change in the condition (financial or otherwise), business prospects,
   net worth or results of operations of the Company and its subsidiaries,
   except as described in or contemplated by the Prospectus (or, if the
   Prospectus is not in existence, the most recent Preliminary Prospectus).

              (xxiv)   Each certificate signed by any officer of the Company and
   delivered to the Representatives or counsel for the Underwriters shall be
   deemed to be a representation and warranty by the Company to each Underwriter
   as to the matters covered thereby.

              (xxv)    Except for the shares of capital stock of each of the
   subsidiaries owned by the Company and such subsidiaries, neither the Company
   nor any such subsidiary owns any shares of stock or any other equity
   securities of any corporation or has any equity interest in any firm,
   partnership, association or other entity, except as described in or
   contemplated by the Prospectus (or, if the Prospectus is not in existence,
   the most recent Preliminary Prospectus).

              (xxvi)   Neither the Company nor any of its subsidiaries is in

   any of its subsidiaries is in violation in any respect of any statute, law,
   governmental rule, regulation, order or decree of any court or governmental
   agency or body to which it or its property is subject or by which it or its
   property may be affected in any material adverse respect with regard to
   property, business or operations of the Company and its subsidiaries. No
   default exists, and no event has occurred which, with notice or lapse of time
   or both, would constitute a default in the due performance and observance of
   any term, covenant or condition of any indenture, mortgage, deed of trust,
   lease or other agreement or instrument to which the Company or any of its
   subsidiaries is a party or by which the Company or any of its subsidiaries or
   any of their respective properties is bound or may be affected in any
   material adverse respect with regard to property, business or operations of
   the Company and its subsidiaries.

              (xxvii)  The Company has filed with the Commission all annual
   reports, quarterly reports, current reports, proxy or information statements,

                                       8
<PAGE>
 
   and no such filings contained an untrue statement of any material fact or
   omitted to state any material fact required to be stated in it or necessary
   in order to make the statements made in it, in light of the circumstances
   under which they were made, not misleading.

              (xxviii) The Company has not distributed and, prior to the later
   of (A) the Closing Date and (B) the completion of the distribution of the
   Securities, will not distribute any offering material in connection with the
   offering and sale of the Securities other than the Registration Statement or
   any amendment thereto, any Preliminary Prospectus or the Prospectus or any
   amendment or supplement thereto, or other materials, if any, permitted by the
   Act.

              (xxix)    The Company confirms as of the date hereof that it is in
   compliance with all provisions of Section 1 of Laws of Florida, Chapter

   person or affiliate located in Cuba changes in any material way, the Company
   will provide the Department notice of such business or change, as
   appropriate, in a form acceptable to the Department.

              (iii)  The Selling Stockholder has not, directly or indirectly,

guaranteed, representing the Selling Stockholder's Firm Securities, all in such

York Clearing House bank and payable in next-day funds to the order of the
Company and the Selling Stockholder. Such delivery of and payment for the Firm
Securities shall be made at the offices of Testa, Hurwitz & Thibeault, Exchange
Place, 53 State Street, Boston, Massachusetts at 9:30 A.M., Boston time, on
__________ __, 1995, or at such other place, time or date as the
Representatives, the Company and the Selling Stockholder may agree upon or as
the Representatives may determine pursuant to Section 9 hereof, such time and
date of delivery against payment being herein referred to as the "Firm Closing
Date". The Company and the Selling Stockholder will make such certificate or
certificates for the Firm Securities available for checking and packaging by the
Representatives at the offices in New York, New York of the Company's transfer
agent or registrar or of Prudential Securities Incorporated at least 24 hours
prior to the Firm Closing Date.

         (b)  For the purpose of covering any over-allotments in connection with
the distribution and sale of the Firm Securities as contemplated by the
Prospectus, the Company hereby grants to the several Underwriters an option to
purchase the Option Securities. The purchase price to be paid for any Option
Securities shall be the same price per share as the price per share for the Firm
Securities set forth above in paragraph (a) of this Section 3. The option
granted hereby may be exercised as to all or any part of the Option Securities
within thirty days after the date of the Prospectus (or, if such 30th day shall
be a Saturday or Sunday or a holiday, on the next business day thereafter when
the New York Stock Exchange is open for trading). The Underwriters shall not be
under any obligation to purchase any of the Option Securities prior to the
exercise of such option. The Representatives may from time to time exercise the
option granted hereby by giving notice in writing or by telephone (confirmed in
writing) to the Company setting forth the aggregate number of Option Securities
as to which the several Underwriters are then exercising the option and the date
and time for delivery of and payment for such Option Securities. Any such date
of delivery shall be determined by the Representatives but shall not be earlier
than two business days or later than seven business days after such exercise of
the option and, in any event, shall not be earlier than the Firm Closing Date.
The time and date set forth in such notice, or such other time on such other
date as the Representatives and the Company may agree upon or as the
Representatives may determine pursuant to Section 9 hereof, is herein called the
"Option Closing Date" with respect to such Option Securities. Upon exercise of
the option as provided herein, the Company shall become obligated to sell to
each of the several Underwriters, and, subject to the terms and conditions
herein set forth, each of the Underwriters (severally and not jointly) shall
become obligated to purchase from the Company, the same percentage of the total
number of the Option Securities as to which the several Underwriters are then
exercising the option as such Underwriter is obligated to purchase of the
aggregate number of Firm Securities, as adjusted by the Representatives in such
manner as they deem advisable to avoid fractional shares. If the option is
exercised as to all or any portion of the Option Securities, one or more
certificates in definitive form for such Option Securities, and payment
therefor, shall be delivered on the related Option Closing Date in the manner,
and upon the terms and conditions, set forth in paragraph (a) of this Section 3,
except that reference therein to the Firm Securities and the Firm Closing Date
shall be deemed, for purposes of this paragraph (b), to refer to such Option
Securities and Option Closing Date, respectively.

         (c)  It is understood that any of you, individually and not as one of
the Representatives, may (but shall not be obligated to) make payment on behalf
of any Underwriter or Underwriters for any of the Securities to be purchased by
such Underwriter or 

                                       11
<PAGE>
 
Underwriters. No such payment shall relieve such Underwriter or Underwriters
from any of its or their obligations hereunder.

     4.  Offering by the Underwriters.  Upon your authorization of the release
         ----------------------------
of the Firm Securities, the several Underwriters propose to offer the Firm
Securities for sale to the public upon the terms set forth in the Prospectus.

         (a)  The Company covenants and agrees with each of the Underwriters
that:

              (i)    The Company will use its best efforts to cause the
   Registration Statement, if not effective at the time of execution of this
   Agreement, and any amendments thereto to become effective as promptly as
   possible. If required, the Company will file the Prospectus and any amendment
   or supplement thereto with the Commission in the manner and within the time
   period required by Rule 424(b) under the Act. During any time when a
   prospectus relating to the Securities is required to be delivered under the
   Act, the Company (A) will comply with all requirements imposed upon it by the
   Act and the Exchange Act and the respective rules and regulations of the
   Commission thereunder to the extent necessary to permit the continuance of
   sales of or dealings in the Securities in accordance with the provisions
   hereof and of the Prospectus, as then amended or supplemented, and (B) will
   not file with the Commission the prospectus or the amendment referred to in
   the second sentence of Section 2(a)(i) hereof, any amendment or supplement to
   such prospectus or any amendment to the Registration Statement of which the
   Representatives shall not previously have been advised and furnished with a
   copy for a reasonable period of time prior to the proposed filing and as to
   which filing the Representatives shall not have given their consent. The
   Company will prepare and file with the Commission, in accordance with the
   rules and regulations of the Commission, promptly upon request by the
   Representatives or counsel for the Underwriters, any amendments to the
   Registration Statement or amendments or supplements to the Prospectus that
   may be necessary or advisable in connection with the distribution of the
   Securities by the several Underwriters, and will use its best efforts to
   cause any such amendment to the Registration Statement to be declared
   effective by the Commission as promptly as possible. The Company will advise
   the Representatives, promptly after receiving notice thereof, of the time
   when the Registration Statement or any amendment thereto has been filed or
   declared effective or the Prospectus or any amendment or supplement thereto
   has been filed and will provide evidence satisfactory to the Representatives
   of each such filing or effectiveness.

              (ii)   The Company will advise the Representatives, promptly after
   receiving notice or obtaining knowledge thereof, of (A) the issuance by the
   Commission of any stop order suspending the effectiveness of the Registration
   Statement or any post-effective amendment thereto or any order directed at
   any document incorporated by reference in the Registration Statement or the
   Prospectus or any amendment or supplement thereto or any order preventing or
   suspending the use of any Preliminary Prospectus or the Prospectus or any
   amendment or supplement thereto, (B) the suspension of the qualification of
   the Securities for offering or sale in any jurisdiction, (C) the institution,
   threat or contemplation of any proceeding for any such purpose or 

                                       12
<PAGE>
 
   (D) any request made by the Commission for amending the Registration
   Statement, for amending or supplementing any Preliminary Prospectus or the
   Prospectus or for additional information. The Company will use its best
   efforts to prevent the issuance of any such stop order and, if any such stop
   order is issued, to obtain the withdrawal thereof as promptly as possible.

              (iii)  The Company will arrange for the qualification of the
   Securities for offering and sale under the securities or blue sky laws of
   such jurisdictions as the Representatives may designate and will continue
   such qualifications in effect for as long as may be necessary to complete the
   distribution of the Securities, provided, however, that in connection
                                   --------  -------
   therewith the Company shall not be required to qualify as a foreign
   corporation or to execute a general consent to service of process in any
   jurisdiction.

              (iv)   If, at any time prior to the later of (A) the final date
   when a prospectus relating to the Securities is required to be delivered
   under the Act or (B) the Option Closing Date, any event occurs as a result of
   which the Prospectus, as then amended or supplemented, would include any
   untrue statement of a material fact or omit to state a material fact
   necessary in order to make the statements therein, in the light of the
   circumstances under which they were made, not misleading, or if for any other
   reason it is necessary at any time to amend or supplement the Prospectus to
   comply with the Act, the Exchange Act or the respective rules or regulations
   of the Commission thereunder, the Company will promptly notify the
   Representatives thereof and, subject to Section 5(a)(i) hereof, will prepare
   and file with the Commission, at the Company's expense, an amendment to the
   Registration Statement or an amendment or supplement to the Prospectus that
   corrects such statement or omission or effects such compliance.

              (v)    The Company will, without charge, provide (A) to the
   Representatives and to counsel for the Underwriters a signed copy of the
   registration statement originally filed with respect to the Securities and
   each amendment thereto (in each case including exhibits thereto), (B) to each
   other Underwriter, a conformed copy of such registration statement and each
   amendment thereto (in each case without exhibits thereto) and (C) so long as
   a prospectus relating to the Securities is required to be delivered under the
   Act, as many copies of each Preliminary Prospectus or the Prospectus or any
   amendment or supplement thereto as the Representatives may reasonably

   available to its stockholders and to the Representatives a consolidated
   earnings statement of the Company and its subsidiaries that satisfies the
   provisions of Section 11(a) of the Act and Rule 158 thereunder.

   set forth in Section 7(h)) as described in Note (8) of Notes to Consolidated
   Financial Statements included in the Registration Statement and the issuance
   of shares of Common Stock upon the exercise of stock options outstanding
   under such stock option plans.

   Closing Date, any rumor, publication or event relating to or affecting the
   Company shall occur as a result of which in your opinion the market price of
   the Common Stock has been or is likely to be materially affected (regardless
   of whether such rumor, publication or event necessitates a supplement to or
   amendment of the Prospectus), the Company will, after written notice from you
   advising the Company to the effect set forth above, forthwith prepare,
   consult with you concerning the substance of, and disseminate a press release
   or other public statement, reasonably satisfactory to you, responding to or
   commenting on such rumor, publication or event.

              (xii)  The Company will cause the Securities to be duly included
   for quotation in the Nasdaq National Market prior to the Firm Closing Date.

   stock of the Company substantially similar thereto legally or beneficially
   owned by such Selling Stockholder or any securities convertible into, or
   exchangeable or exercisable for, shares of Common Stock or other capital
   stock of the Company for a period of 120 days after the date hereof.

of a material fact or omitted to state any material fact required to be stated
therein or necessary to make the statements therein not misleading or that the
Prospectus, as of its date or the date of such opinion, included or includes any
untrue statement of a material fact or omitted or omits to state a material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

     In rendering any such opinion, such counsel may rely, as to matters of
fact, to the extent such counsel deems proper, on certificates of responsible
officers of the Company and public officials.

     References to the Registration Statement and the Prospectus in this
paragraph (b) shall include any amendment or supplement thereto at the date of
such opinion.

         (c)  The Selling Stockholder shall have furnished to the
Representatives the opinion of Hutchins, Wheeler & Dittmar, counsel for the

              (i)    the Selling Stockholder is the record owner of the
   Securities to be sold by him, has full power to enter into this Agreement and
   to sell, transfer and deliver the Securities being sold by the Selling
   Stockholder hereunder in the manner provided in this Agreement; this
   Agreement has been duly executed and delivered by the Selling Stockholder;

              (ii)   the delivery by the Selling Stockholder to the several
   Underwriters of certificates for the Securities being sold hereunder by the
   Selling Stockholder against payment therefor as provided herein, will convey
   good and marketable title to such Securities to the several Underwriters,
   free and clear of all security interests, liens, encumbrances, equities,
   claims or other defects; and

              (iii)  the sale of the Securities to the Underwriters by the
   Selling Stockholder pursuant to this Agreement, the compliance by the Selling
   Stockholder with the other provisions of this Agreement and the consummation
   of the other transactions herein contemplated do not (A) require the consent,
   approval, authorization, registration 

                                       19

   or qualification of or with any governmental authority, except as such as
   have been obtained and such as may be required by the National Association of
   Securities Dealers, Inc. or under state securities or blue sky laws, or (B)
   conflict with or result in a breach or violation of any of the terms and
   provisions of, or constitute a default under any indenture, mortgage, deed of
   trust, lease or other agreement or instrument to which the Selling
   Stockholder is a party or by which the Selling Stockholder or any of the
   Selling Stockholder's properties are bound, or any statute, rule or
   regulation or any judgment, decree or order of any court or other
   governmental authority or any arbitrator known to such counsel applicable to
   the Selling Stockholder.

     In rendering such opinion, such counsel may rely, as to matters of fact, to
the extent such counsel deems proper, on certificates of the Selling Stockholder
and public officials.

     References to the Registration Statement and the Prospectus in this
paragraph (c) shall include any amendment or supplement thereto at the date of
such opinion.

         (d)  The Representatives shall have received an opinion, dated the Firm
Closing Date, of Testa, Hurwitz & Thibeault, counsel for the Underwriters, with
respect to the issuance and sale of the Firm Securities, the Registration
Statement and the Prospectus, and such other related matters as the
Representatives may reasonably require, and the Company shall have furnished to
such counsel such documents as they may reasonably request for the purpose of
enabling them to pass upon such matters.

         (e)  The Representatives shall have received from Arthur Andersen LLP a
letter or letters dated, respectively, the date hereof, the Firm Closing Date
and the Option Closing Date, if applicable, in form and substance satisfactory
to the Representatives, to the effect that:

              (i)    they are independent accountants with respect to the
   Company and its consolidated subsidiaries within the meaning of the Act, the
   Exchange Act and the applicable rules and regulations thereunder; 

              (ii)   in their opinion, the audited consolidated financial
   statements and schedules examined by them and included in the Registration
   Statement and the Prospectus comply in form in all material respects with the
   applicable accounting requirements of the Act, the Exchange Act and the
   related published rules and regulations thereunder;

              (iii)  on the basis of a reading of the latest available interim
   unaudited consolidated financial statements of the Company and its
   consolidated subsidiaries for the three months ended April 1, 1995 and of the
   unaudited consolidated financial statements of the Company and its
   consolidated subsidiaries for the period from which such amounts are derived,
   carrying out certain specified procedures (which do not constitute an
   examination made in accordance with generally accepted auditing standards)
   that would not necessarily reveal matters of significance with respect to the
   comments set forth in this paragraph (iii), a reading of the minute books of
   the stockholders, the board of directors and any committees thereof of the
   Company and each of its consolidated subsidiaries, and inquires of certain
   officials of the Company and its consolidated subsidiaries who have

                                       20
<PAGE>
 
   responsibility for financial and accounting matters, nothing came to their
   attention that caused them to believe that:
                            
                     (A) the unaudited consolidated financial statements of the 
   Company and its consolidated subsidiaries included in the Registration
   Statement and the Prospectus do not comply in form in all material respects
   with the applicable accounting requirements of the Act, the Exchange Act and
   the related published rules and regulations thereunder, or are not in
   conformity with generally accepted accounting principles applied on a basis
   substantially consistent with that of the audited consolidated financial
   statements included in the Registration Statement and the Prospectus; and 
       
                     (B) at a specific date not more than five business days
   prior to the date of the letter delivered on the date hereof and not more
   than two business days prior to the date of the letters delivered on the Firm
   Closing Date and on the Option Closing Date, respectively, there were any
   changes in the capital stock or long-term debt of the Company and its
   consolidated subsidiaries or any decreases in net current assets or
   stockholders' investment of the Company and its consolidated subsidiaries, in
   each case compared with amounts shown on the April 1, 1995 unaudited
   consolidated balance sheet of the Company and its consolidated subsidiaries
   included in the Registration Statement and the Prospectus, or for the period
   from April 1, 1995 to such specified date, there were any decreases, as
   compared with the corresponding period in the prior year, in consolidated net
   sales, income from operations, net income before provision for income taxes
   or total or per share amounts of net income of the Company and its
   consolidated subsidiaries, except in all instances for changes, decreases or
   increases set forth in such letter; and     
       
              (iv)   they have carried out certain specified procedures, not
   constituting an audit, with respect to certain amounts, percentages and
   financial information that are derived from the general accounting records of
   the Company and its consolidated subsidiaries and are included in the
   Registration Statement and the Prospectus under the captions Prospectus
   Summary, Risk Factors, Use of Proceeds, Capitalization, Selected Consolidated
   Financial Data, Management's Discussion and Analysis of Financial Condition
   and Results of Operations, Business, Description of Capital Stock and Shares
   Eligible for Future Sale or under the caption Executive Compensation
   contained in the Company's Proxy Statement dated April 28, 1995 for the
   Company's Special Meeting in Lieu of Annual Meeting of Stockholders to be
   held on May 25, 1995 incorporated by reference in the Registration Statement
   and the Prospectus, and have compared such amounts, percentages and financial
   information with such records of the Company and its consolidated
   subsidiaries and with information derived from such records and have found
   them to be in agreement, excluding any questions of legal interpretation.

     In the event that the letters referred to above set forth any such changes,
decreases or increases, it shall be a further condition to the obligations of
the Underwriters that (A) such letters shall be accompanied by a written
explanation of the Company as to the significance thereof, unless the
Representatives deem such explanation unnecessary, and (B) such changes,
decreases or increases do not, in the sole judgment of the Representatives, make
it impractical or inadvisable to proceed with the purchase and delivery of the
Securities as contemplated by the Registration Statement, as amended as of the
date hereof.

     References to the Registration Statement and the Prospectus in this
paragraph (e) with respect to the letters referred to above shall include any

   described in or contemplated by the Prospectus.

         (g)  The Representatives shall have received a certificate from the

     8.  Indemnification and Contribution.
         --------------------------------

         (a)  The Company and the Selling Stockholder, jointly and severally,
agree to indemnify and hold harmless each Underwriter and each person, if any,
who controls any Underwriter within the meaning of Section 15 of the Act or
Section 20 of the Exchange Act against any losses, claims, damages or
liabilities, joint or several, to which such Underwriter or such controlling
person may become subject under the Act, the Exchange Act or otherwise, insofar
as such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of or are based upon:

              (i)    any untrue statement or alleged untrue statement made by
   the Company or the Selling Stockholder in Section 2 of this Agreement,

              (ii)   any untrue statement or alleged untrue statement of any
   material fact contained in (A) the Registration Statement or any amendment
   thereto, any Preliminary Prospectus or the Prospectus or any amendment or
   supplement thereto or (B) any application or other document, or any amendment
   or supplement thereto, executed by the Company or the Selling Stockholder
   filed in any jurisdiction in order to qualify the Securities under the
   securities or blue sky laws thereof or filed with the Commission or any
   securities association or securities exchange (each an "Application"),

              (iii)  the omission or alleged omission to state in the
   Registration Statement or any amendment thereto, any Preliminary Prospectus
   or the Prospectus or any amendment or supplement thereto, or any Application
   a material fact required to be stated therein or necessary to make the
   statements therein not misleading, or

              (iv)   any untrue statement or alleged untrue statement of any
   material fact contained in any audio or visual materials prepared and
   supplied by the Company to the Underwriters to be used in connection with the
   marketing of the Securities, including without limitation, slides, videos,
   films, tape recordings,

and will reimburse, as incurred, each Underwriter and each such controlling
person for any legal or other expenses reasonably incurred by such Underwriter
or such controlling person in connection with investigating, defending against
or appearing as a third-party witness in connection with any such loss, claim,
damage, liability or action; provided, however, that the Company and the Selling
                             --------  -------
Stockholder will not be liable in any such case to the extent that any such
loss, claim, damage or liability arises out of or is based upon any untrue
statement or alleged untrue statement or omission or alleged omission made in
such registration statement or any amendment thereto, any Preliminary
Prospectus, the Prospectus or any amendment or supplement thereto, or any
Application in reliance upon and in conformity with written information
furnished to the Company or the Selling Stockholder by such Underwriter through
the Representatives specifically for use therein; and provided, further, that
                                                      --------  -------
the Company and the Selling Stockholder will not be liable to any Underwriter or
any person controlling such Underwriter with respect to any such untrue
statement or omission made in any Preliminary Prospectus that is corrected in
the Prospectus (or any amendment or supplement thereto) if the person asserting
any such loss, claim, damage or liability purchased Securities from such
Underwriter but was not sent or given a copy of the Prospectus (as amended or
supplemented) at or prior to the written confirmation of the sale of such
Securities to such person in any case 

                                       24
<PAGE>
 
where such delivery of the Prospectus (as amended or supplemented) is required
by the Act, unless such failure to deliver the Prospectus (as amended or
supplemented) was a result of noncompliance by the Company with Section 5(a)(iv)
and (v) of this Agreement. Notwithstanding anything to the contrary in this
paragraph 8(a), including the joint and several nature of the obligations of the
Company and the Selling Stockholder, each Underwriter and each person who
controls such Underwriter agrees not to assert its rights to indemnity against
the Selling Stockholder for losses, claims, damages or liabilities (or actions
in respect thereof) arising out of or based upon any untrue statement or alleged
untrue statement made by such Selling Stockholder in Section 2(a) of this
Agreement, unless and until (i) such Underwriter or controlling person has
requested indemnification and reimbursement from the Company for such losses,
claims, damages or liabilities (including any legal or other expenses reasonably
incurred) and (ii) the Company does not within 30 days of such request (A) agree
to so indemnify such Underwriter or controlling person and (B) reimburse in full
such Underwriter or controlling person for any such losses, damages or
liabilities (including legal and other expenses) incurred. This indemnity
agreement will be in addition to any liability which the Company and the Selling
Stockholder may otherwise have. Neither the Company nor the Selling Stockholder
will, without the prior written consent of the Underwriter or Underwriters
purchasing, in the aggregate, more than fifty percent (50%) of the Securities,
settle or compromise or consent to the entry of any judgment in any pending or
threatened claim, action, suit or proceeding in respect of which indemnification
may be sought hereunder (whether or not any such Underwriter or any person who
controls any such Underwriter within the meaning of Section 15 of the Act or
Section 20 of the Exchange Act is a party to such claim, action, suit or
proceeding), unless such settlement, compromise or consent includes an
unconditional release of all of the Underwriters and such controlling persons
from all liability arising out of such claim, action, suit or proceeding.

         (b)  Each Underwriter, severally and not jointly, will indemnify and
hold harmless the Company, each of its directors, each of its officers who
signed the Registration Statement, each person, if any, who controls the Company
within the meaning of Section 15 of the Act or Section 20 of the Exchange Act
and the Selling Stockholder against any losses, claims, damages or liabilities
to which the Company, any such director, officer or controlling person of the
Company or the Selling Stockholder may become subject under the Act, the
Exchange Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon (i)
any untrue statement or alleged untrue statement of any material fact contained
in the Registration Statement or any amendment thereto, any Preliminary
Prospectus or the Prospectus or any amendment or supplement thereto, or any
Application or (ii) the omission or the alleged omission to state therein a
material fact required to be stated in the Registration Statement or any
amendment thereto, any Preliminary Prospectus or the Prospectus or any amendment
or supplement thereto, or any Application necessary to make the statements
therein not misleading, in each case to the extent, but only to the extent, that
such untrue statement or alleged untrue statement or omission or alleged
omission was made in reliance upon and in conformity with written information
furnished to the Company by any Underwriter through the Representatives
specifically for use therein; and, subject to the limitation set forth
immediately preceding this clause, will reimburse, as incurred, any legal or
other expenses reasonably incurred by the Company, any such director, officer or
controlling person or the Selling Stockholder in connection with investigating
or defending any such loss, claim, damage, liability or any action in respect

                                       25
<PAGE>
 
thereof. This indemnity agreement will be in addition to any liability which
such Underwriter may otherwise have.

         (c)  Promptly after receipt by an indemnified party under this Section
8 of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 8, notify the indemnifying party of the commencement thereof; but the
omission so to notify the indemnifying party will not relieve it from any
liability which it may have to any indemnified party otherwise than under this
Section 8. In case any such action is brought against any indemnified party, and
it notifies the indemnifying party of the commencement thereof, the indemnifying
party will be entitled to participate therein and, to the extent that it may
wish, jointly with any other indemnifying party similarly notified, to assume
the defense thereof, with counsel satisfactory to such indemnified party;
provided, however, that if the defendants in any such action include both
- --------  -------
the indemnified party and the indemnifying party and the indemnified party shall
have reasonably concluded that there may be one or more legal defenses available
to it and/or other indemnified parties which are different from or additional to
those available to the indemnifying party, the indemnifying party shall not have
the right to direct the defense of such action on behalf of such indemnified
party or parties and such indemnified party or parties shall have the right to
select separate counsel to defend such action on behalf of such indemnified
party or parties.  After notice from the indemnifying party to such indemnified
party of its election so to assume the defense thereof and approval by such
indemnified party of counsel appointed to defend such action, the indemnifying
party will not be liable to such indemnified party under this Section 8 for any
legal or other expenses, other than reasonable costs of investigation,
subsequently incurred by such indemnified party in connection with the defense
thereof, unless (i) the indemnified party shall have employed separate counsel
in accordance with the proviso to the next preceding sentence (it being
understood, however, that in connection with such action the indemnifying party
shall not be liable for the expenses of more than one separate counsel (in
addition to local counsel) in any one action or separate but substantially
similar actions in the same jurisdiction arising out of the same general
allegations or circumstances, designated by the Representatives in the case of
paragraph (a) of this Section 8, representing the indemnified parties under such
paragraph (a) who are parties to such action or actions) or (ii) the
indemnifying party does not promptly retain counsel satisfactory to the
indemnified party or (iii) the indemnifying party has authorized the employment
of counsel for the indemnified party at the expense of the indemnifying party.
After such notice from the indemnifying party to such indemnified party, the
indemnifying party will not be liable for the costs and expenses of any
settlement of such action effected by such indemnified party without the consent
of the indemnifying party.

         (d)  The liability of the Selling Stockholder under this Section 8
shall not exceed the lesser of (i) that percentage of the total amount of such
losses, claims, damages or liabilities for which the Underwriters or any persons
controlling such Underwriters are entitled to indemnity hereunder equal to the
percentage obtained by dividing the total number of Securities sold by the
Selling Stockholder hereunder by the total number of Securities sold hereunder
or (ii) an amount equal to the initial public offering price of the Securities
sold by the Selling Stockholder to the Underwriters (less underwriting discounts
and commissions), except in the case of any liability arising as a result of any
untrue statements or alleged untrue statements of the Selling Stockholder in
Sections 2(b)(i), (ii), (iii) or (v) where the liability of the Selling
Stockholder shall not exceed the amount set forth in (ii) of this paragraph (d).

                                       26
<PAGE>
 
         (e)  In circumstances in which the indemnity agreement provided for in
the preceding paragraphs of this Section 8 is unavailable or insufficient, for
any reason, to hold harmless an indemnified party in respect of any losses,
claims, damages or liabilities (or actions in respect thereof), each
indemnifying party, in order to provide for just and equitable contribution,
shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages or liabilities (or actions in respect
thereof) in such proportion as is appropriate to reflect (i) the relative
benefits received by the indemnifying party or parties on the one hand and the
indemnified party on the other from the offering of the Securities or (ii) if
the allocation provided by the foregoing clause (i) is not permitted by
applicable law, not only such relative benefits but also the relative fault of
the indemnifying party or parties on the one hand and the indemnified party on
the other in connection with the statements or omissions or alleged statements
or omissions that resulted in such losses, claims, damages or liabilities (or
actions in respect thereof), as well as any other relevant equitable
considerations. The relative benefits received by the Company and the Selling
Stockholder on the one hand and the Underwriters on the other shall be deemed to
be in the same proportion as the total proceeds from the offering (before
deducting expenses) received by the Company and the Selling Stockholder bear to
the total underwriting discounts and commissions received by the Underwriters.
The relative fault of the parties shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by the Company, the Selling Stockholder or the
Underwriters, the parties' relative intents, knowledge, access to information
and opportunity to correct and prevent such statement or omission, and any other
equitable considerations appropriate in the circumstances. The Company, the
Selling Stockholder and the Underwriters agree that it would not be equitable if
the amount of such contribution were determined by pro rata or per capita
allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation that does not take into account
the equitable considerations referred to above in this paragraph (e).
Notwithstanding any other provision of this paragraph (e), no Underwriter shall
be obligated to make contributions hereunder that in the aggregate exceed the
total public offering price of the Securities purchased by such Underwriter
under this Agreement, less the aggregate amount of any damages that such
Underwriter has otherwise been required to pay in respect of the same or any
substantially similar claim, and no person guilty of fraudulent
misrepresentation (within the meaning of Section 11(e) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. The Underwriters' obligations to contribute hereunder are
several in proportion to their respective underwriting obligations and not
joint, and contributions among Underwriters shall be governed by the provisions
of the Prudential Securities Incorporated Master Agreement Among Underwriters.
For purposes of this paragraph (e), each person, if any, who controls an
Underwriter within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act shall have the same rights to contribution as such Underwriter, and
each director of the Company, each officer of the Company who signed the
Registration Statement and each person, if any, who controls the Company or the
Selling Stockholder within the meaning of Section 15 of the Act or Section 20 of
the Exchange Act, shall have the same rights to contribution as the Company or
the Selling Stockholder, as the case may be.

     9.  Default of Underwriters.  If one or more Underwriters default in their
         -----------------------
obligations to purchase Firm Securities or Option Securities hereunder and the
aggregate 

                                       27
<PAGE>
 
number of such Securities that such defaulting Underwriter or Underwriters
agreed but failed to purchase is ten percent or less of the aggregate number of
Firm Securities or Option Securities to be purchased by all of the Underwriters
at such time hereunder, the other Underwriters may make arrangements
satisfactory to the Representatives for the purchase of such Securities by other
persons (who may include one or more of the non-defaulting Underwriters,
including the Representatives), but if no such arrangements are made by the Firm
Closing Date or the related Option Closing Date, as the case may be, the other
Underwriters shall be obligated severally in proportion to their respective
commitments hereunder to purchase the Firm Securities or Option Securities that
such defaulting Underwriter or Underwriters agreed but failed to purchase. If
one or more Underwriters so default with respect to an aggregate number of
Securities that is more than ten percent of the aggregate number of Firm
Securities or Option Securities, as the case may be, to be purchased by all of
the Underwriters at such time hereunder, and if arrangements satisfactory to the
Representatives are not made within 36 hours after such default for the purchase
by other persons (who may include one or more of the non-defaulting
Underwriters, including the Representatives) of the Securities with respect to
which such default occurs, this Agreement will terminate without liability on
the part of any non-defaulting Underwriter or the Company other than as provided
in Section 10 hereof. In the event of any default by one or more Underwriters as
described in this Section 9, the Representatives shall have the right to
postpone the Firm Closing Date or the Option Closing Date, as the case may be,
established as provided in Section 3 hereof for not more than seven business
days in order that any necessary changes may be made in the arrangements or
documents for the purchase and delivery of the Firm Securities or Option
Securities, as the case may be. As used in this Agreement, the term
"Underwriter" includes any person substituted for an Underwriter under this
Section 9. Nothing herein shall relieve any defaulting Underwriter from
liability for its default.

     10. Survival.  The respective representations, warranties, agreements,
         --------- 
covenants, indemnities and other statements of the Company, its officers, the
Selling Stockholder and the several Underwriters set forth in this Agreement or

on behalf of the Company, any of its officers or directors, the Selling
Stockholder, any Underwriter or any controlling person referred to in Section 8
hereof and (ii) delivery of and payment for the Securities.  The respective
agreements, covenants, indemnities and other statements set forth in Sections 6

Securities or any Option Securities in the sole discretion of the
Representatives by notice to the Company and the Selling Stockholder given prior

the event that the Company or the Selling Stockholder shall have failed, refused
or been unable to perform all obligations and satisfy all conditions on its part
to be performed or satisfied hereunder at or prior thereto or, if at or prior to
the Firm Closing Date or such Option Closing Date, respectively,

              (i)    the Company or any of its subsidiaries shall have, in the
   sole judgment of the Representatives, sustained any material loss or
   interference with their

   prospects, net worth or results of operations of the Company and its
   subsidiaries, except in each case as described in or contemplated by the
   Prospectus (exclusive of any amendment or supplement thereto);

   United States or (C) any other calamity or crisis or material adverse change
   in general economic, political or financial conditions having an effect on

   the delivery of the Securities as contemplated by the Registration Statement,
   as amended as of the date hereof.

    6.   Other lawful provisions for the conduct and regulation of the 
business and affairs of the corporation, for its voluntary dissolution, or for 
limiting, defining, or regulating the powers of the corporation, or of its 
directors or stockholders, or of any class of stockholders:

         No Director or Officer shall be disqualified by his office from 
dealing or contracting as vendor, purchaser or otherwise, whether in his

firm in which he is interested as stockholder, director, trustee, partner or 
otherwise, with the corporation or any corporation, trust, association or firm

or relaxed by the stockholders at a meeting called for the purpose.

stockholder, director, trustee, partner or otherwise, with the corporation or 
any corporation, trust, association or firm in which the corporation shall be 
a stockholder or otherwise interested or which shall hold stock or be 
otherwise interested in the corporation, nor shall any such dealing or 
contract be avoided, nor shall any stockholder so dealing or contracting be 
liable to account for any profit or benefit realized through any such contract 
or dealing to the corporation or to any stockholder or creditor thereof by 
reason of such stockholder holding stock in the corporation to any amount, nor 
shall any fiduciary relationship be deemed to be established by such 
stockholding.

         Meetings of the stockholders of the corporation may be held at any 
place within the United States.

    RESOLVED: To amend the Articles of Organization of this 
              Corporation by adding at Article 6 thereof the 
              following:

              Any amendment of the Articles of Organization of 
              this Corporation, other than amendments which 
              would have been governed by Section 70 of Chapter 
              156B of the General Laws, as the same exists on 
              the date of adoption of this amendment of the 
              Articles, shall require the affirmative vote of 
              two-thirds of the shares of each class of stock 
              of this Corporation outstanding and entitled to 
              vote thereon.

              Any sale, lease or exchange of all or 
              substantially all of the property and assets, 
              including good will, of this Corporation shall 
              require the affirmative vote of two-thirds of the 
              shares of each class of stock of this Corporation 
              outstanding and entitled to vote thereon; 
              provided, however, that the mortgage or pledge 
              of, or granting a security interest in, all or 
              substantially all of the property and assets, of 
              the Corporation, including good will, shall not 
              require the authorization or consent of 
              stockholders.

              Any agreement of merger or consolidation to which 
              this Corporation is a party which would have been 
              governed by Section 78 or 79 of said 
              Chapter 156B, as they exist on the date of the 
              adoption of this amendment, shall require the 
              affirmative vote of two-thirds of the shares of 
              each class of stock of this Corporation 
              outstanding and entitled to vote thereon; 
              provided, however, that no stockholder approval 
              by this Corporation shall be required of any 
              agreement of merger under which this Corporation 
              is the surviving corporation if the conditions 
              set forth in Section 78(c)(2) of said Chapter 
              156B, as it exists on the date of adoption of 
              this amendment, are satisfied.

              And that the President and Clerk of this 
              Corporation be and they hereby are authorized and 
              directed to execute and file Articles of 
              Amendment to the Articles of Organization of this 
              Corporation and that the proper fee be paid to 
              the Secretary of the Commonwealth.  The foregoing 
              Sections 70, 78 and 79 of said Chapter 156B, as

         A corporation may authorize, at a meeting duly called 
for the purpose, an amendment of its articles of organization, 
by vote of a majority of each class of stock outstanding and 
entitled to vote thereon effecting any one or more of the 
following:

         (a)  an increase or a reduction of its capital stock 
of any class then authorized;

         (b)  a change of the par value of its authorized 
shares with par value or any class thereof;

         (c)  a change of its authorized shares with par value 
or any class thereof into any number of shares without par 
value, or the exchange thereof pro rata for any number of 
shares without par value;

         (d)  a change of its authorized shares without par 
value or any class thereof into a greater or lesser number of 
shares without par value, or the exchange thereof pro rata for 
a greater or lesser number of shares without par value;

         (e)  a change of its authorized shares, with par value 
or any class thereof into a greater or lesser number of shares 
with par value, or the exchange thereof pro rata for a greater

value or any class thereof into any number of shares with par 
value, or the exchange thereof pro rata for any number of 
shares with par value;

         (g)  a change of its corporate name.

         Any reference in this section to any change with 
respect to authorized shares shall be deemed to refer to and 
include both the unissued and the outstanding shares; provided, 
however, that any change which impairs or diminishes the 
preferences, voting powers, restrictions (including 
restrictions on transfer) qualifications, special or relative 
rights or privileges of any outstanding shares may be 
authorized only in accordance with the provisions of section 
seventy-one.  The aggregate par value of shares becoming 
outstanding by virtue of any change or exchange effected 
pursuant to the provisions of this section or of section 
seventy-one shall not exceed the amount of capital shown on the 
balance sheet of the corporation with respect to the 
outstanding shares so changed or exchanged, plus the amount of 
any surplus which shall be appropriated to capital in 
connection with such change or exchange (1964, 723, (S)1.)

         (a)   Any two or more corporations may consolidate to 
form a new corporation, or may merge into a single corporation, 
which may be any one of the constituent corporations, in the 
manner specified in this section.

         (b)   Such corporations as desire to consolidate or 
merge shall enter into an agreement of consolidation or merger 
signed by the president or a vice president and the treasurer 
or an assistant treasurer and under the corporate seals of the 
respective corporations, which shall set forth:

         (1)   The names of the corporations proposing to 
consolidate or merge and the name of the resulting or surviving 
corporation;

         (2)   The purposes of the resulting or surviving 
corporation;

         (3)   The total number of shares and the par value, if 
any, of each class of stock which the resulting or surviving 
corporation is authorized to issue;

         (4)   If more that one class of stock is to be 
authorized at the effective date of the agreement, a 
description of each class, with the preferences, voting powers, 
qualifications, special or relative rights or privileges as to 
each class and any series thereof then established;

         (5)   The terms and conditions of the consolidation or 
merger;

         (6)   The manner of converting the shares of each of 
the constituent corporations into shares or securities of the 
resulting or surviving corporation, or the cash or other 
consideration to be paid or delivered in exchange for shares of 
each constituent corporation; provided, however, that the 
aggregate par value of the shares with a par value of the 
resulting or surviving corporation plus the aggregate principal 
amount of any securities representing indebtedness of the 
surviving or resulting corporation substituted upon conversion 
for previously issued and outstanding shares of the constituent 
corporations shall not exceed the aggregate value of the assets 
less the aggregate amount of the liabilities of the constituent 
corporations; and

         (7)   The manner of fixing the effective date of the 
consolidation or merger, which may be the date of filing the 
articles of consolidation or articles of merger with the state 
secretary pursuant to subsection (d), or any specified date not 
more than thirty days after such filing.

                             - B1 -
<PAGE>
 
         The agreement of consolidation or merger may contain 
such other provisions as are permitted by section thirteen of  
this chapter to be included in the articles of organization of 
a corporation, together with any provisions deemed necessary or 
desirable in connection with the consolidation or merger, 
including without limitation a provision permitting the 
abandonment thereof, which are not inconsistent with the 
provisions of this chapter.

         (c)(1)  Except as provided in paragraph (2) of this 
subsection:

         (i)   The agreement of consolidation or merger shall 
be submitted to the stockholders of each constituent 
corporation at a meeting thereof called for the purpose of 
considering and acting upon the same.

         (ii)  Notice of the time, place and purposes of such 
meeting shall be given to each stockholder of record, whether 
or not entitled to vote thereat, of each such corporation in 
the manner provided in section thirty-six but at least thirty 
days prior to the date of such meeting.

         (iii) Subject to the provisions of section eight, the 
vote of two-thirds of the shares of each class of stock of each 
constituent corporation outstanding and entitled to vote on the 
question, or, if the articles of organization so provide, the 
vote of a lesser proportion but not less than a majority of 
each class of stock of each constituent corporation outstanding 
and entitled to vote on the question, shall be necessary for 
the approval of such agreement.  For this purpose, if any such 
agreement would adversely affect the rights of any class of 
stock of either constituent corporation, the vote in the 
proportion provided for in this section of the shares of such 
class then outstanding, voting separately, shall also be 
necessary to authorize such agreement.  Any series of a class 
which is adversely affected in a manner different from other 
series of the same class shall, together with any other series 
of the same class adversely affected in the same manner, be 
treated as a separate class.

         (2)   Unless required by its articles of organization, 
the agreement of merger need not be submitted to the 
stockholders of a constituent corporation surviving the merger 
but may be approved by vote of its directors if:

         (i)   The agreement of merger does not change the 
name, the amount of shares authorized of any class of stock or 
other provisions of the articles of organization of such 
corporation;

                             - B2 -
<PAGE>
 
         (ii)  The authorized unissued shares or shares held in 
the treasury of such corporation of any class of stock of such 
corporation to be issued or delivered pursuant to the agreement 
of merger do not exceed fifteen per centum of the shares of 
such corporation of the same class outstanding immediately 
prior to the effective date of the merger; and

         (iii) The issue by vote of the directors of any 
unissued stock to be issued pursuant to the agreement of merger 
has been authorized in accordance with section twenty-one.

         (d)   Unless such agreement to consolidate or merge is 
abandoned pursuant to provisions contained therein:  (1) an 
original or attested copy thereof shall be kept in the 
commonwealth by the resulting or surviving corporation in one 
of the offices specified in section thirty-two for inspection 
by any of its stockholders or by any person who was a 
stockholder of any constituent corporation; (2) the resulting 
or surviving corporation shall furnish a copy of the agreement 
of consolidation or merger to any such stockholder or person 
upon written request and without charge; (3) articles of 
consolidation or merger shall be submitted to the state 
secretary which shall set forth the due adoption of an 
agreement of consolidation or merger in accordance with 
subsections (b) and (c) and shall state:  (i) the names of the 
constituent corporations and the name of the resulting or 
surviving corporation; (ii) the effective date of the 
consolidation or merger determined pursuant to the agreement of 
consolidation or merger; (iii) any amendment to the articles of

         (a)   the purposes of the resulting corporation;

         (b)   the total number of shares and the par value, if

authorized, a description of each class, with the preferences, 
voting powers, qualifications, special or relative rights or 
privileges as to each class and any series thereof then 
established; and

         (d)   such other provisions as are permitted by 
section thirteen to be included in the articles of organization 
of a corporation and are contained in the agreement of 
consolidation; and (iv) that the resulting or surviving 

                             - B3 -
<PAGE>
 
corporation will furnish a copy of the agreement of 
consolidation or merger to any of its stockholders or to any 
person who was a stockholder of any constituent corporation 
upon written request and without charge.  Such articles of 
consolidation or merger shall be signed by the president or a 
vice president and the clerk or an assistant clerk of each 
constituent corporation, who shall state under the penalties of 
perjury that the agreement of consolidation or merger has been 
duly executed on behalf of such corporation and has been 
approved in the manner required by this section by the 
stockholders of such corporation or, if permitted under 
subsection (c), by the directors of such corporation.  (Amended 
by 1980, 365, (S)1, approved July 3, 1980, effective 90 days 
thereafter.)

         The form on which articles of consolidation or merger 
are filed shall also contain the following information which 
shall not for any purpose be treated as a permanent part of the

commonwealth;

         (2)  the name, residence and post-office address of

corporation initially adopted;

         (4)  the date initially fixed in the by-laws for the 
annual meeting of stockholders of the resulting or surviving 
corporation.

         The consolidation or merger shall become effective 
when the articles of consolidation or merger are filed in 
accordance with section six, unless said articles specify a 
later effective date not more than thirty days after such 
filing, in which event the consolidation or merger shall become 
effective on such later date.

         (e)  The resulting or surviving corporation shall file 
a copy of the articles of consolidation or merger certified by 
the state secretary in the registry of deeds in each district 
within the commonwealth in which real property of any 
constituent corporation is situated, or in lieu of such 
certified copy a certificate issued pursuant to section 
eighty-four, except that no filing need be made with respect to 
real property of a constituent corporation which is the 
surviving corporation of a merger.  (Amended by 1980, 245, (S)1, 
approved June 6, 1980, effective 90 days thereafter.)

         (a)  Any one or more corporations may consolidate or 
merge with one or more other corporations organized under the 
laws of any other state or states of the United States, if the 
laws of such other state or states permit.  The constituent 
corporations may consolidate to form a new corporation, which 
may be a corporation of the state under the laws of which any 
one of the constituent corporations is organized, or they may 
merge into a single corporation, which may be any one of the 
constituent corporations.

         (b)  Such corporations as desire to consolidate or 
merge shall enter in an agreement of consolidation or merger 
which shall specify the state under the laws of which the 
resulting or surviving corporation is organized.  If the 
resulting or surviving corporation is to be a Massachusetts 
corporation such agreement of consolidation or merger shall 
comply with the provisions of section seventy-eight, and if the 
resulting or surviving corporation is to be governed by the 
laws of another state the agreement of consolidation or merger 
shall comply with the applicable provisions of the laws of such 
other state.  If the resulting or surviving corporation is to 
be governed by the laws of another state, the resulting or 
surviving corporation shall agree that it may be sued in this 
commonwealth for any prior obligation of any constituent 
domestic corporation, any prior obligation of any constituent 
foreign corporation qualified under chapter one hundred and 
eighty-one, and any obligation thereafter incurred by the 
resulting or surviving corporation, including the obligation 
created by section eighty-five, so long as any liability 
remains outstanding against the corporation in this 
commonwealth, and it shall irrevocably appoint the state 
secretary as its agent to accept service of process in any 
action for the enforcement of any such obligation, including 
taxes, in the same manner as provided in chapter one hundred 
and eighty-one.

         (c)  The agreement of consolidation or merger shall be 
adopted by each of the constituent corporations in accordance 
with the laws of the state under which it is organized, and in 
the case of a Massachusetts corporation in the manner provided 
in section seventy-eight.  Unless such agreement is abandoned 
pursuant to provisions contained therein:  (1) an original or 
attested copy thereof shall be kept in the commonwealth by the 
resulting or surviving corporation in one of the offices 
specified in section thirty-two if the resulting or surviving 
corporation is to be a Massachusetts corporation, or if said 

                             - C1 -
<PAGE>
 
corporation is to be governed by the laws of another state, 
wherever the records of meetings of its stockholders are 
required or permitted by such laws to be kept, and shall be 
made available at said location for inspection by any 
stockholder of the resulting or surviving corporation or any 
person who was a stockholder of any constituent corporation; 
(2) the resulting or surviving corporation shall furnish a copy 
of the agreement of consolidation or merger to any such 
stockholder or person upon written request and without charge; 
(3) articles of consolidation or merger shall be submitted to 
the state secretary, which shall set forth the information 
required by clauses (i) to (iv), inclusive, of paragraph 3 of 
subsection (d) of section seventy-eight, and shall be signed by 
the president or a vice president and the clerk or an assistant 
clerk of each constituent corporation, or, in the case of a 
corporation organized under the laws of another state, by 
officers having corresponding powers and duties, who shall make 
affidavit or state under the penalties of perjury (i) in the 
case of each constituent corporation not organized under the 
laws of Massachusetts, that the agreement has been duly adopted 
under the laws of the state under which such constituent 
corporation is organized, and (ii) in the case of each 
constituent corporation organized under the laws of 
Massachusetts, that the agreement has been duly executed by the 
officers and has been approved in the manner required by 
section seventy-eight by the stockholders of such corporation 
or, if permitted under subsection (c) of section seventy-eight, 
by the directors of such corporation.  If the resulting or 
surviving corporation is to be governed by the laws of 
Massachusetts, the form on which articles of consolidation or 
merger are filed shall contain the further information required 
by subsection (d) of section seventy-eight in the case of 
articles of consolidation or merger filed thereunder, which as 
set forth in said subsection (d) shall not for any purpose be 
treated as a permanent part of the articles of organization of 
the resulting or surviving corporation.  The consolidation or 
merger shall become effective when the articles of 
consolidation or merger are filed in accordance with section 
six, unless said articles specify a later effective date not 
more than thirty days after such filing, in which event the 
consolidation or merger shall become effective on such later 
date.  (Amended by 1980, 365 (S)2, approved July 3, 1980, 
effective 90 days thereafter.)

         (d)  The resulting or surviving corporation shall file 
a copy of the articles of consolidation or merger certified by 
the state secretary in the registry of deeds in each district 
within the commonwealth in which real property of any 
constituent corporation is situated, or in lieu of such 
certified copy a certificate issued pursuant to section 
eighty-four, except that no filing need be made with respect to 
real property of a constituent corporation which is the 
surviving corporation of a merger.  (Amended by 1980, 245, (S)2, 
approved June 6, 1980, effective 90 days thereafter.)

                  DESCRIPTION OF CAPITAL STOCK
                  ----------------------------

         A.   Authorized Shares.  The aggregate number of 
              -----------------
shares which this Corporation shall have authority to issue is 
11,000,000 shares consisting of 10,000,000 shares of common 
stock having a par value of $0.05 per share (the "Common 
Stock") and 1,000,000 shares of preferred stock having a par 
value of $1.00 per share (the "Preferred Stock").

         B.   Preferred Stock.  Shares of Preferred Stock may 
              ---------------
be issued from time to time in one or more series as may from 
time to time be determined by the Board of Directors, each of 
said series to be distinctly designated.  All shares of any one 
series of Preferred Stock shall be alike in every particular, 
except that there may be different dates from which dividends, 
if any, thereon shall be cumulative, if made cumulative.  The 
voting powers, if any, and the designations, preferences and 
relative, participating, optional or other special rights or 
privileges of each such series, and the qualifications, 
limitations or restrictions thereof, if any, may differ from 
those of any and all other series at any time outstanding; and, 
subject to the provisions of subparagraph 1 of Paragraph D 
hereof, there is hereby expressly vested in the Board of 
Directors of the Corporation the authority to issue one of more 
series of Preferred Stock and to fix in the resolution or 
resolutions providing for the issue of such stock adopted by 
the Board of Directors of the Corporation the voting powers, if 
any, and the designations, preferences and relative, 
participating, optional or other special rights or privileges,

series, including, but without limiting the generality of the 
foregoing, the following:

         shares of Preferred Stock which shall constitute such 
         series.  The designation of a series of preferred 
         stock need not include the words "preferred" or 
         "preference" and may be designated "special" or other 
         distinctive term.  Unless otherwise provided in the 
         resolution issuing such series, the number of shares 
         of any series of Preferred Stock may be increased or 
         decreased (but not below the number of shares thereof 
         then outstanding) by the Board of Directors in the 
         manner prescribed by law;
<PAGE>

         conditions upon which, dividends, if any, on Preferred 
         Stock of such series shall be paid, the extent of the 
         preference or relation, if any, of such dividends to 
         the dividends payable on any other class or classes, 
         or series of the same or other classes of stock and 
         whether such dividends shall be cumulative or 
         non-cumulative and, if cumulative, the date from which 
         such dividends shall be cumulative;

         (3)  Whether the series shall be convertible into, or 
         exchangeable for, at the option of the holders of 
         Preferred Stock of such series or the Corporation or 
         upon the happening of a specified event, shares of any 
         other class or classes or any other series of the same 
         or any other class or classes of stock of the 
         Corporation, and the terms and conditions of such 
         conversion or exchange, including provisions for the 
         adjustment of any such conversion rate in such events 
         as the Board of Directors shall determine;

         (4)  Whether or not Preferred Stock of such series 
         shall be subject to redemption at the option of the 
         Corporation or the holders of such series or upon the 
         happening of a specified event, and the redemption 
         price or prices and the time or times at which, and 
         the terms and conditions upon which, Preferred Stock 
         of such series may be redeemed;

         (5)  The rights, if any, of the holders of Preferred 
         Stock of such series upon the voluntary or involuntary 
         liquidation, merger, consolidation, distribution or 
         sale of assets; dissolution or winding-up, of the 
         Corporation;

         (6)  The terms of the sinking fund or redemption or 
         purchase account, if any, to be provided for the 
         Preferred Stock of such series; and

         (7)  Subject to subparagraph 5 of Paragraph D hereof, 
         whether such series of Preferred Stock shall have 
         full, limited or no voting powers including, without 
         limiting the generality of the foregoing, whether such 
         series shall have the right, voting as a series by 
         itself or together with other series of Preferred 
         Stock or all series of Preferred Stock as a class, to 
         elect one or more directors of the Corporation if 
         there shall have been a default in the payment of 
         dividends on any one or more series of Preferred Stock 
         or under such other circumstances and on such 
         conditions as the Board of Directors may determine.

         preferences among such series), and subject further to 
         any other conditions which may be fixed in accordance 
         with the provisions of Paragraph B hereof, then, and 
         not otherwise, the holders of Common Stock shall be 
         entitled to receive such dividends (either in cash, 
         stock or otherwise) as may be declared from time to 
         time by the Board of Directors out of assets of the 
         Corporation legally available therefor and the holders 
         of the Preferred Stock shall not be entitled to 
         participate in any such dividends.

         (2)  After distribution in full of the preferential 
         amount, if any, to be distributed to the holders of 
         series of Preferred Stock (in accordance with the 
         relative preferences among such series) in the event 
         of voluntary or involuntary liquidation, distribution, 
         dissolution or winding-up, of the Corporation, the 
         holders of the Common Stock shall be entitled to 
         receive all of the remaining assets of the 
         Corporation, tangible and intangible of whatever kind 
         available for distribution to shareholders, ratably in 
         proportion to the number of shares of Common Stock 
         held by them respectively.

         (3)  Except as may otherwise be required by law, each 
         holder of Common Stock shall have one vote in respect 
         of each share of Common Stock held by him on all 
         matters voted upon by the shareholders.

         D.   Other Provisions.
              ----------------

         (1)  No holder of any of the shares of any class or 
         series of stock or of options, warrants or other 
         rights to purchase shares of any class or series of 
         stock or of other securities of the Corporation shall 
         have any preemptive right to purchase or subscribe for 
         any unissued stock of any class or series or any 
         additional shares of any class or series to be issued 
         by reason of any increase of the authorized capital 
         stock of the Corporation of any class or series, or 
<PAGE>
 
         bonds, certificates of indebtedness, debentures or 
         other securities convertible into or exchangeable for 
         stock of the Corporation of any class or series, or 
         carrying any right to purchase stock of any class or 
         series, but any such unissued stock, additional 
         authorized issue of shares of any class or series of 
         stock or securities convertible into or exchangeable 
         for stock, or carrying any right to purchase stock,

         of the Board of Directors to such persons, firms, 
         corporations or associations (including such holders 
         or others) and upon such terms as may be deemed 
         advisable by the Board of Directors in the exercise of 
         its sole discretion.

         (2)  The relative powers, preferences and rights of 
         each series of Preferred Stock in relation to the 
         powers, preferences and rights of each other series of 
         Preferred Stock shall, in each case, be as fixed from 
         time to time by the Board of Directors in the 
         resolution or resolutions adopted pursuant to 
         authority granted in Paragraph B hereof.  The consent, 
         by class or series vote or otherwise, of the holders 
         of such of the series of Preferred Stock as are from 
         time to time outstanding shall not be required for the 
         issuance by the Board of Directors of any other series 
         of Preferred Stock whether or not the powers, 
         preferences and rights of such other series shall be 
         fixed by the Board of Directors as senior to, or on a 
         parity with, the powers, preferences and rights of 
         such outstanding series, or any of them; provided, 
         however, that the Board of Directors may provide in 
         the resolution or resolutions as to any series of 
         Preferred Stock adopted pursuant to Paragraph B 
         hereof, the conditions, if any, under which the 
         consent of the holders of a majority (or such greater 
         proportion as shall be fixed therein) of the 
         outstanding shares of such series shall be required 
         for the issuance of any or all other series of 
         Preferred Stock. 

            (3)    Subject to the provisions of subparagraph 2 
         of this Paragraph D, shares of any series of Preferred 
         Stock may be issued from time to time as the Board of 
         Directors of the Corporation shall determine and on 
         such terms and for such consideration as shall be 
         fixed by the Board of Directors. 

         (4)  Shares of authorized Common Stock may be issued 
         from time to time as the Board of Directors of the 
<PAGE>
 
         Corporation shall determine and on such terms and for 
         such consideration as shall be fixed by the Board of 
         Directors.

         (5)  The number of authorized shares of Common Stock 
         and of Preferred Stock, may without a class or series 
         vote, be increased or decreased from time to time (but 
         not below the number of shares thereof then 
         outstanding) by the affirmative vote of the holders of 
         a majority of the stock of the Corporation entitled to 
         vote thereon.

Altron Incorporated
One Jewel Drive
Wilmington, MA 01887-3390
 
Ladies and Gentlemen:
 
  We have acted as counsel to Altron Incorporated, a Massachusetts corporation
(the "Company"), in connection with the proceedings being taken to register
under the Securities Act of 1933, as amended, up to 1,380,000 shares of the
Company's common stock, par value $.05 per share (the "Common Stock"), pursuant
to a Registration Statement on Form S-3 (File No. 33-58287) (the "Registration
Statement"). The Registration Statement relates to the proposed public offering
by the Company of 1,280,000 shares of Common Stock (assuming the exercise in
full of the over-allotment option described in the Registration Statement) and
to the proposed public offering by a shareholder of the Company (the "Selling
Shareholder") of 100,000 shares of Common Stock.
 
  Based upon such investigation as we have deemed necessary and having regard
for such legal considerations as we deem relevant, we are of the opinion that:
 
    1. The Company is a corporation duly organized, validly existing and in
  corporate good standing under the laws of the Commonwealth of
  Massachusetts.
 
    2. The Company is authorized to issue 30,000,000 shares of Common Stock,
  par value $.05 per share, and 1,000,000 shares of Preferred Stock, par
  value $1.00 per share.
 
    3. When issued and sold under the circumstances contemplated in the
  Registration Statement, the maximum of 1,280,000 shares of Common Stock
  being offered by the Company will be validly issued, fully paid and
  nonassessable, and the maximum of 100,000 shares of Common Stock being
  offered by the Selling Shareholder will be validly issued, fully paid and
  nonassessable.
 
    We hereby consent to the filing of this opinion as an Exhibit to the
  Registration Statement and to the references to us under the heading "Legal
  Matters" in the prospectus forming a part of the Registration Statement.
 
                                          Very truly yours,

                                          /s/ Hutchins, Wheeler & Dittmar
