                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by the more detailed
information, including the financial statements and notes thereto, appearing
elsewhere in this Prospectus. Unless otherwise indicated, the information in
this Prospectus assumes that (i) the Underwriters' over-allotment options will
not be exercised, (ii) all outstanding shares of Series A Convertible Preferred
Stock, par value $.01 per share, will be converted into Common Stock upon the
closing of this Offering and (iii) the Company's Restated Articles of
Organization will be amended upon the closing of this Offering to reduce the
number of authorized shares of Preferred Stock, par value $.01 per share, from
2,000,000 to 1,000,000 shares and to eliminate all shares of Series A
Convertible Preferred Stock. The Company's fiscal year begins on July 1 and ends
on June 30 of each year. See "Description of Capital Stock" and "Underwriting."
 
     Mercury designs, manufactures and markets high performance, real-time
digital signal processing computer systems that transform sensor generated data
into information which can be displayed as images for human interpretation or
subjected to additional computer analysis. These multicomputer systems are
heterogeneous and scalable, allowing them to accommodate several microprocessor
types and to scale from a few to hundreds of microprocessors within a single
system. Mercury's system architecture is specifically designed for digital
signal processing applications which are typically computation intensive and
require I/O capacity and interprocessor bandwidth not available on a general
purpose PC or workstation. The two primary markets for Mercury's products are
defense electronics and medical diagnostic imaging. Both of these markets have
computing needs which benefit from the unique system architecture developed by
the Company. Mercury's computer systems are generally used on real world signal
data to enable a military commander to "see" the battle space through natural
barriers such as clouds, darkness, water or foliage, so that the position and
strength of the enemy can be determined, or to enable a physician to "see"
within the body instead of performing invasive surgery.
 
     During the past three fiscal years, the majority of the Company's revenues
has been generated from sales of its products to the defense electronics market,
generally for use in intelligence gathering electronic warfare systems. The
Company's activities in this area have focused on the proof of concept,
development and deployment of advanced military applications in radar, sonar and
airborne surveillance. The Company has established relationships with many of
the major prime contractors to the worldwide defense industry, including
Lockheed Martin Corporation, Hughes Aircraft Company, Raytheon/E-Systems, Inc.,
Raytheon/TI Systems, Inc., Northrop Grumman Corporation, MIT/Lincoln Laboratory,
GEC Marconi Limited, Ericsson Microwave Systems AB, MATRA Systemes &
Information, Mitsubishi Heavy Industries, Ltd. and a prime contractor owned by
the Israeli Ministry of Defense.
 
     Medical diagnostic imaging is the other primary market currently served by
the Company. Mercury's computer systems are embedded in magnetic resonance
imaging ("MRI"), computed tomography ("CT") and positron emission tomography
("PET") machines. Mercury has supplied computer systems for use in several of
General Electric Medical Systems, Inc.'s medical diagnostic imaging systems
since 1987, and has established relationships with Siemens Medical Systems,
Inc., Toshiba Corp. and Elscint, Inc. The major medical imaging manufacturers
are currently developing the next generation of MRI, CT and digital x-ray
machines, which are expected to provide better performance at lower cost.
Mercury has recently secured design wins on programs with certain of the major
medical imaging manufacturers for their next generation MRI, CT and digital
x-ray machines. The Company believes that the available market in 1998 for
digital signal processing systems and upgrades for the MRI, CT and digital x-ray
markets is expected to be an aggregate of approximately $123 million.
 
     Mercury's computer systems are designed to process continuous streams of
data from sensors attached to radar, sonar, medical imaging equipment and other
devices. The resulting image is transmitted to the battlefield commander, pilot,
technician or physician in order to assist in the decision making or diagnostic
process. Due to the nature of the applications in which many of Mercury's
computer systems are embedded, they are frequently confined in limited spaces
and therefore are designed to generate a minimum amount of heat. The Company
employs the RACEway Interconnect, an industry standard system area network


================================================================================
 
                                        3

developed by Mercury which allows for high interprocessor bandwidth and I/O
capacity. The Company uses its proprietary application specific integrated
circuits ("ASICs") to integrate microprocessors, memory and related components
into the RACEway Interconnect to provide optimum system performance. The Company
uses industry standard microprocessors, such as Intel Corporation's i860,
Motorola, Inc.'s PowerPC, Texas Instruments Incorporated's C80 and Analog
Devices, Inc.'s SHARC, in the same system. The Company believes that the RACEway
Interconnect and its proprietary ASICs, working together with a group of mixed
microprocessors in the same system, allow the most efficient use of space and
power with an optimal price/performance ratio.
 
     Since July 1996, Mercury has targeted the shared storage market for
introduction of a new product which draws on the Company's core competencies in
systems engineering and the development of real-time software. In fiscal 1997,
Mercury introduced SuiteFusion, its first shared storage product designed to
meet the needs of the broadcast and post-production industry. SuiteFusion is an
open, scalable software application that allows work groups to share commodity,
fibre channel attached disk arrays, eliminating the need for an expensive,
intermediate file server. Early end users include Turner Broadcasting Systems
Inc.'s CNN Interactive, Nickelodeon's Blue's Clues television show and Hughes
Aircraft (through a subsidiary) for use at the U.S. Army National Training
Center. The Company believes that the shared storage market includes a number of
distinct applications, such as digital video editing, electronic computer aided
design, webcasting, cable advertising insertion and pre-press.
 
     The Company's executive offices are located at 199 Riverneck Road,
Chelmsford, Massachusetts 01824, and its telephone number is (978) 256-1300. The
Company was incorporated in Massachusetts in 1981.

                                  RISK FACTORS
 
     An investment in the Common Stock offered hereby involves a high degree of
risk. Prospective investors should carefully consider the following risk
factors, in addition to the other information set forth in this Prospectus, in
connection with an investment in the shares of Common Stock offered hereby.
 
     When used in this Prospectus, the words "may," "will," "expect,"
"anticipate," "continue," "estimate," "project," "intend" and similar
expressions are intended to identify forward-looking statements regarding
events, conditions and financial trends that may affect the Company's future
plans of operations, business strategy, results of operations and financial
position. Prospective investors are cautioned that any forward-looking
statements are not guarantees of future performance and are subject to risks and
uncertainties and that actual results may differ materially from those included
within the forward-looking statements as a result of various factors. Factors
that could cause or contribute to such differences include, but are not limited
to, those described below, under the heading "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and elsewhere in this
Prospectus.
 
     DEPENDENCE ON DEFENSE ELECTRONICS BUSINESS; UNCERTAINTY ASSOCIATED WITH
GOVERNMENT CONTRACTS. Sales of the Company's computer systems to the defense
electronics market accounted for approximately 81% of the Company's revenues in
fiscal 1997, compared to approximately 72% of the Company's revenues in fiscal
1996. Reductions in government spending on programs that incorporate the
Company's products could have a material adverse effect on the Company's
business, financial condition and results of operations. Moreover, the Company's
government contracts and subcontracts are subject to special risks, such as:
delays in funding; ability of the government agency to unilaterally terminate
the prime contract; reduction or modification in the event of changes in
government policies or as the result of budgetary constraints or political
changes; increased or unexpected costs under fixed price contracts; and other
factors that are not under the control of the Company. In addition,
consolidation among defense industry contractors has resulted in fewer
contractors with increased bargaining power relative to the Company. No
assurance can be given that such increased bargaining power will not adversely
affect the Company's business, financial condition or results of operations in
the future.
 
     The Company's contracts with the U.S. and foreign governments and their
prime and subcontractors are subject to termination either upon default by the
Company or at the convenience of the government. Termination for convenience
provisions generally entitle the Company to recover costs incurred, settlement
expenses and profit on work completed prior to termination. In addition to the
right of the government to terminate, government contracts are generally
conditioned upon the continuing availability of legislative appropriations.
Funds are usually appropriated for a given program each fiscal year even though
contract performance may take more than one fiscal year. Consequently, at the
outset of a major program, the contract is usually partially funded, and
additional monies normally are incrementally committed to the contract by the
procuring agency from appropriations made for future fiscal years. No assurance
can be given that the Company will realize the revenue expected from performing
under such contracts. Because the Company contracts to supply goods and services
to U.S. and foreign governments it is also subject to other risks, including
contract suspensions, protests by disappointed bidders of contract awards which
can result in the reopening of the bidding process, changes in governmental
policies or regulations or other political factors.
 
     DEPENDENCE ON KEY CUSTOMERS.  The Company is dependent on a small number of
customers for a large portion of its revenues. In fiscal 1997, Lockheed Martin
and Hughes Aircraft accounted for 22% and 10%, respectively, of the Company's
revenues, and sales to 20 customers accounted for more than 80% of the Company's
fiscal 1997 revenues. In fiscal 1996, Lockheed Martin, GE Medical and Hughes
Aircraft accounted for 19%, 16% and 12%, respectively, of the Company's
revenues, and sales to 20 customers accounted for more than 80% of the Company's
fiscal 1996 revenues. The Company's largest customer in the medical imaging
market is GE Medical, which accounted for 72% of the Company's aggregate sales
to the medical imaging market in fiscal 1997, compared to 69% of sales to the
medical imaging market in fiscal 1996. Customers in the defense electronics
market generally purchase the Company's products in connection with government
programs that have a limited duration, leading to fluctuating sales to any
particular customer in the defense electronics market from year to year. By
contrast, many customers in the medical imaging market
 
                                        6
<PAGE>   10
 
historically have purchased the Company's products over a number of years for
use in successive generations of medical imaging devices, although there can be
no assurance that such past behavior will continue in the future. A significant
diminution in the sales to or loss of any of the Company's major customers would
have a material adverse effect on the Company's business, financial condition
and results of operations. In addition, the Company's revenues are largely
dependent upon the ability of its customers to develop and sell products that
incorporate the Company's products. No assurance can be given that the Company's
customers will not experience financial or other difficulties that could
adversely affect their operations and, in turn, the results of operations of the
Company. See "Business -- Markets and Customers."
 
     FLUCTUATIONS IN OPERATING RESULTS.  The Company has experienced
fluctuations in its results of operations in large part due to the sale by the
Company of its computer systems in relatively large dollar amounts to a
relatively small number of customers. Operating results also have fluctuated due
to competitive pricing programs and volume discounts, the loss of customers,
market acceptance of the Company's products, product obsolescence and general
economic conditions. In addition, the Company, from time to time, has entered
into contracts to engineer a specific solution based on modifications to the
Company's standard products (a "development contract"). The Company's gross
margins from development contract revenues are typically lower than the
Company's gross margins from standard product revenues. The Company intends to
continue to enter into development contracts and anticipates that the gross
margins associated with development contract revenues will continue to be lower
than its gross margins on standard product revenues. The Company expects
research and development expenses to continue to increase as the Company
continues to develop products to serve its markets, all of which are subject to
rapidly changing technology, frequent product performance improvements and
evolving industry standards. The ability to deliver superior technological
performance on a timely and cost effective basis is a critical factor in
securing design wins for future generations of defense electronics and medical
imaging systems. Significant research and development spending by the Company
does not ensure that the Company's computer systems will be designed into a
customer's system. Because future production orders are usually contingent upon
securing a design win, the Company's operating results may fluctuate due to
either obtaining or failing to obtain design wins for significant customer
systems.
 
     The Company's quarterly results may be subject to fluctuations resulting
from the foregoing factors, as well as a number of other factors, including the
timing of significant orders, delays in completion of internal product
development projects, delays in shipping the Company's computer systems and
software programs, delays in acceptance testing by customers, a change in the
mix of products sold to the defense electronics and medical imaging markets,
production delays due to quality problems with outsourced components, shortages
of components, the timing of product line transitions and declines in quarterly
revenues from old generations of products following announcement of replacement
products containing more advanced technology. Another factor contributing to
fluctuations in quarterly results is the fixed nature of the Company's
expenditures on personnel, facilities and marketing programs. The Company's
expense levels for personnel, facilities and marketing programs are based, in
significant part, on the Company's expectations of future revenues on a
quarterly basis. If actual quarterly revenues are below management's
expectations, results of operations likely will be adversely affected. As a
result of the foregoing factors, the Company's operating results, from time to
time, may be below the expectations of public market analysts and investors,
which could have a material adverse effect on the price of the Company's Common
Stock. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations."
 
     DEPENDENCE ON SUPPLIERS.  Several components used in the Company's products
are currently obtained from sole source suppliers. Mercury is dependent on LSI
Logic Corporation for four custom designed ASICs, on Analog Devices for its
SHARC processors, on International Business Machines Corporation for ball grid
array packaging, on Motorola for its PowerPC processors and on Intel for its
i860 processors. IBM may terminate its contract with the Company without cause
upon thirty days notice and may cease offering products to the Company upon
sixty days notice. Analog Devices may discontinue or modify any product upon 180
days notice and LSI Logic may discontinue any product upon 180 days notice. If
LSI Logic, Analog Devices, IBM, Motorola or Intel were to limit or reduce the
sale of such components to the Company, or if these or other suppliers to the
Company were to experience financial difficulties or other problems which
 
                                        7
<PAGE>   11
 
prevented them from supplying the Company with the necessary components, such
events could have a material adverse effect on the Company's business, financial
condition and results of operations. These sole source suppliers are subject to
quality and performance issues, materials shortages, excess demand, reduction in
capacity and other factors that may disrupt the flow of goods to the Company or
its customers and thereby adversely affect the Company's business and customer
relationships. The Company has no guaranteed supply arrangements with its
suppliers and there can be no assurance that its suppliers will continue to meet
the Company's requirements. If the Company's supply arrangements are
interrupted, there can be no assurance that the Company would be able to find
another supplier on a timely or satisfactory basis. Any shortage or interruption
in the supply of any of the components used in the Company's products, or the
inability of the Company to procure these components from alternate sources on
acceptable terms could have a material adverse effect on the Company's business,
financial condition and results of operations. There can be no assurance that
severe shortages of components will not occur in the future. Such shortages
could increase the cost or delay the shipment of the Company's products, which
could have a material adverse effect on the Company's business, financial
condition and results of operations. Significant increases in the prices of
these components would also materially adversely affect the Company's financial
performance since the Company may not be able to adjust product pricing to
reflect the increase in component costs. The Company could incur set-up costs
and delays in manufacturing should it become necessary to replace any key
vendors due to work stoppages, shipping delays, financial difficulties or other
factors and, under certain circumstances, these costs and delays could have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Business -- Manufacturing and Testing."
 
     DEPENDENCE UPON KEY PERSONNEL AND SKILLED EMPLOYEES.  The Company is
largely dependent upon the skills and efforts of its senior management,
particularly James R. Bertelli, its President and Chief Executive Officer, as
well as its managerial, sales and technical employees. None of the senior
management or other key employees of the Company is subject to any employment
contract or noncompetition agreement. The Company maintains key-man life
insurance on Mr. Bertelli and certain other senior managers. The loss of
services of any of its executives or other key personnel could have a material
adverse effect on the Company's business, financial condition and results of
operations. The Company's future success will depend to a significant extent on
its ability to attract, train, motivate and retain highly skilled technical
professionals, particularly project managers, engineers and other senior
technical personnel. The Company believes that there is a shortage of, and
significant competition for, technical development professionals with the skills
and experience necessary to perform the services offered by the Company. The
Company's ability to maintain and renew existing engagements and obtain new
business depends, in large part, on its ability to hire and retain technical
personnel with the skills that keep pace with continuing changes in industry
standards, technologies and client preferences. The inability to hire additional
qualified personnel could impair the Company's ability to satisfy its growing
client base, requiring an increase in the level of responsibility for both
existing and new personnel. There can be no assurance that the Company will be
successful in retaining current or future employees.
 
     DEPENDENCE ON MEDICAL IMAGING MARKET; POTENTIAL ADVERSE EFFECT OF HEALTH
CARE REFORM.  Sales of the Company's computer systems to the medical imaging
market accounted for approximately 11% of the Company's revenues in fiscal 1997,
compared to approximately 23% of revenues in fiscal 1996. These customers are
original equipment manufacturers ("OEMs") of medical imaging devices and, as a
result, any change in the demand for such devices which renders any of the
Company's products unnecessary or obsolete, or any change in the technology in
such devices, could have a material adverse effect on the Company's business,
financial condition and results of operations. Such OEM customers, the end-users
of their products and the health care industry generally are subject to
extensive federal, state and local regulation in the U.S. as well as in other
countries. Changes in applicable health care laws and regulations or new
interpretations of existing laws and regulations could have a material adverse
effect on such customers or end-users. There can be no assurance that future
health care or budgetary legislation or other changes in the administration or
interpretation of governmental health care programs both in the U.S. and abroad
will not have a material adverse effect on the Company's business, financial
condition or results of operations.

<PAGE>   12
 
     RISK OF ENTRY INTO NEW MARKETS.  The Company's expansion strategy includes
developing new products and entering new markets. The Company's ability to
compete in new markets will depend upon a number of factors including, without
limitation, the Company's ability to create demand for its products in such
markets, its ability to manage its growth effectively, the quality of its
products, its ability to respond to changes in its customers' businesses by
updating existing products and introducing, in a timely fashion, products which
meet the needs of its customers and the ability of the Company to respond
rapidly to technological change. The failure of the Company to do any of the
foregoing could result in a material adverse effect on its business, financial
condition and results of operations. In addition, the Company may face
competition in these new markets from various companies which may have
substantially greater research and development resources, marketing and
financial resources, manufacturing capability and customer support organizations
than those of the Company.
 
     The Company has recently expanded into the shared storage market and has
invested, and continues to invest, significant resources in the development of
products geared towards that market. The Company has initially focused on
providing software products tailored for the post-production and broadcast
segments of the entertainment industry, introducing in fiscal 1997 SuiteFusion,
a middleware application that enables workgroups to share files. The market for
providing digital and other products to the entertainment industry includes
competitors with greater financial and other resources than the Company. No
assurance can be given that the Company will be able to successfully compete in
this market, or that it will be able to meet the technical specifications
imposed by its customers or potential customers. In addition, the success of the
Company's shared storage software product depends, in large part, on the
post-production and broadcast industry shifting from traditional linear,
tape-based technologies toward newer non-linear, disk-based digital
technologies. Linear, tape-based technologies remain pervasive in this industry
and there can be no assurance that its participants will adopt non-linear,
disk-based digital technologies, or that, if adopted, the Company's products
will not be obsolete, uncompetitive or incompatible. The occurrence of any of
the foregoing could adversely affect the Company's business, financial condition
and results of operations. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
     RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS.  The Company markets and
sells its products in certain international markets, and the Company has
established offices in the United Kingdom, the Netherlands, Japan and France.
The Company's international revenues, which are comprised of export sales to
foreign markets from the United States and sales by foreign subsidiaries, were
approximately 12% of the Company's revenues in fiscal 1997, as compared to
approximately 20% in fiscal 1996. If revenues generated by foreign activities
are not adequate to offset the expense of establishing and maintaining these
foreign subsidiaries and activities, the Company's business, financial condition
and results of operations could be materially adversely affected. In addition,
there are certain risks inherent in transacting business internationally, such
as changes in applicable laws and regulatory requirements, export and import
restrictions, export controls relating to technology, tariffs and other trade
barriers, less favorable intellectual property laws, difficulties in staffing
and managing foreign operations, longer payment cycles, problems in collecting
accounts receivable, political instability, fluctuations in currency exchange
rates, expatriation controls and potential adverse tax consequences, any of
which could adversely impact the success of the Company's international
activities. In the recent past, the financial markets in Asia have experienced
significant turmoil. There can be no assurance that such turmoil in the Asian
financial markets will not negatively affect the sales by the Company to that
region. A portion of the Company's revenues from sales to foreign entities,
including foreign governments, is in the form of foreign currencies. The Company
has no hedging or similar foreign currency contracts, and fluctuations in the
value of foreign currencies could adversely impact the profitability of the
Company's foreign operations. There can be no assurance that one or more of such
factors will not have a material adverse effect on the Company's future
international activities and, consequently, on the Company's business, financial
condition or results of operations.
 
     TECHNOLOGICAL CHANGES; RISK OF DESIGN-IN PROCESS.  The Company's future
success will depend in part on its ability to enhance its current products and
to develop new products on a timely and cost-effective basis in order to respond
to technological developments and changing customer needs. The defense
electronics market, in particular, demands constant technological improvements
as a means of gaining military advantage.

Military planners historically have funded significantly more design projects
than actual deployments of new equipment, and those systems which are deployed
tend to contain the components of the subcontractors selected to participate in
the design process. In order to participate in the design of new defense
electronics systems, the Company must be able to demonstrate its ability to
deliver superior technological performance on a timely and cost-effective basis.
There can be no assurance that the Company will be able to secure an adequate
number of defense electronics design wins in the future, that the equipment in
which the Company's products are intended to function eventually will be
deployed in the field, or that the Company's products will be included in such
equipment if it eventually is deployed.
 
     Customers in the medical imaging market also seek technological
improvements through product enhancements and new generations of products. The
Company believes that medical imaging machines in which the Company's computers
are installed have a long product life cycle. Medical equipment OEMs
historically have selected certain suppliers whose products have been included
in the OEMs' machines for a significant portion of the products' life cycle.
There can be no assurance that the Company will be selected to participate in
the future design of any medical imaging equipment, or that, if selected, the
Company will generate any revenues for such design work. Failure to participate
in future designs of medical imaging equipment could have a material adverse
effect on the Company's business, financial condition and results of operations.
 
     The design-in process is typically lengthy and expensive, and there can be
no assurance that the Company will be able to continue to meet the product
specifications of its customers in a timely and adequate manner. In addition,
any failure by the Company to anticipate or respond adequately to changes in
technology and customer preferences, or any significant delay in product
developments or introductions, could have a material adverse effect on the
Company's business, financial condition and results of operations. Because of
the complexity of its products, the Company has experienced delays from time to
time in completing products on a timely basis. If the Company is unable to
design, develop or introduce competitive new products on a timely basis, its
future operating results would be adversely affected. There can be no assurance
that the Company will be successful in developing new products or enhancing its
existing products on a timely or cost-effective basis, or that such new products
or product enhancements will achieve market acceptance.
 
     COMPETITION.  The markets for the Company's products are highly competitive
and are characterized by rapidly changing technology, frequent product
performance improvements and evolving industry standards. Competition typically
occurs at the design stage, where the customer evaluates alternative design
approaches, including those from internal development organizations. A design
win usually ensures a customer will purchase the product until their next
generation system is developed. Occasionally, the Company's computer systems
compete with computer systems from workstation vendors, all of whom have
substantially greater research and development resources, long term guaranteed
supply capacity, marketing and financial resources, manufacturing capability and
customer support organizations than those of the Company. The Company believes
that its future ability to compete effectively will depend, in part, upon its
ability to continue to improve product and process technologies and develop new
technologies in order to maintain the performance advantages of products and
processes relative to competitors, to adapt products and processes to
technological changes, to identify and adopt emerging industry standards and to
adapt to customer needs.
 
     The principal bases for selection in sales of digital signal processing
systems to the defense electronics industry are performance (measured primarily
in terms of processing speed, I/O capacity and interprocessor bandwidth,
processing density per cubic foot, power consumption and heat dissipation),
systems engineering support, overall quality of products and associated
services, use of industry standards, ease of use and price. Competitors in the
defense electronics industry include a relatively small number of companies that
design, manufacture and market digital signal processor ("DSP") board level
products and in-house design teams employed by prime defense contractors.
In-house design efforts historically have provided a significant amount of
competition to the Company. However, competition from in-house design teams has
diminished in significance in recent years due to the increasing use of
commercial off-the-shelf ("COTS") products and the trend toward greater use of
outsourcing. Despite this recent change, there can be no assurance that in-house
developments will not re-emerge as a major competitive force in the future.
Prime contractors are much larger than Mercury and have substantially more
resources to invest in research and development. Increased use of
 
                                       10
<PAGE>   14
 
in-house design teams by defense contractors in the future may have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
     In the medical imaging industry the principal bases for selection are
performance (measured primarily in terms of processing speed, I/O capacity and
interprocessor bandwidth and power consumption), price, systems engineering
support, overall quality of products and associated services, use of industry
standards and ease of use. Competitors in the medical imaging market include
in-house design teams, a small number of companies that design, manufacture and
market DSP board level products and workstation manufacturers. Workstations have
become a competitive factor primarily in the market for low-end MRI and CT
machines and, to date, have not been a significant factor in the
high-performance market, Mercury's primary focus. There can be no assurance that
workstation manufacturers will not attempt to penetrate the high-performance
market for medical imaging machines. Workstation manufacturers typically have
greater resources than Mercury and their entry into markets historically
targeted by Mercury may have a material adverse effect on the Company's
business, financial condition and results of operations.
 
     Due to the emerging nature of the markets for the Company's shared storage
technology, its competitive factors are not yet clearly defined. The Company
currently is focusing its efforts in this area on the broadcast and
post-production industry, where the Company believes there is currently only one
directly competitive product. As this market develops, the Company anticipates
that other companies will begin offering additional competitive products. New
competitors may have significantly greater marketing and financial resources,
better access to individuals making purchasing decisions, superior products and
superior services than those offered by the Company. The Company believes that
the primary impediment to future sales of shared storage products to the
post-production and broadcast industry is the need to transform entrenched
operating modes, such as those associated with linear tape based technologies,
to accommodate new modes of operation such as those associated with non-linear,
disk-based digital technology. However, there can be no assurance that industry
participants will adopt such new technologies or that, if adopted, the Company's
products will not be obsolete, uncompetitive or incompatible.
 
     Some of the Company's competitors have greater financial and other
resources than the Company, and the Company may be operating at a cost
disadvantage compared to manufacturers who have greater direct buying power from
component suppliers or who have lower cost structures. There can be no assurance
that the Company will be able to compete successfully in the future with any of
these sources of competition. In addition, there can be no assurance that
competitive pressures will not result in price erosion, reduced margins, loss of
market share or other factors, any of which could have a material adverse effect
on the Company's business, financial condition and results of operations. See
"Business -- Competition."
 
     LIMITED PROTECTION OF PROPRIETARY RIGHTS; POTENTIAL INFRINGEMENT OF THIRD
PARTY RIGHTS.  The Company relies on a combination of patent, copyright,
trademark and trade secret laws to establish and protect its rights in its
products and proprietary technology. In addition, the Company currently requires
its employees and consultants to enter into nondisclosure and assignment of
invention agreements to limit use of, access to and distribution of its
proprietary information. There can be no assurance that the Company's means of
protecting its proprietary rights in the U.S. or abroad will be adequate. The
laws of some foreign countries may not protect the Company's proprietary rights
as fully or in the same manner as do the laws of the U.S. Also, despite the
steps taken by the Company to protect its proprietary rights, it may be possible
for unauthorized third parties to copy aspects of the Company's products,
reverse engineer, develop similar technology independently or otherwise obtain
and use information that the Company regards as proprietary. There can be no
assurance that others will not develop technologies similar or superior to the
Company's technology or design around the proprietary rights owned by the
Company. In addition, there can be no assurance that others will not assert
claims of infringement in the future or that, if made, such claims will not be
successful. Litigation to determine the validity of any claims, whether or not
such litigation is determined in favor of the Company, could result in
significant expense to the Company and divert the efforts of the Company's
technical and management personnel from daily operations. In the event of any
adverse ruling in any litigation regarding intellectual property, the Company
may be required to pay substantial damages, discontinue the sale of infringing
products, expend significant resources to develop non-infringing technology or
obtain licenses to infringing or substituted technology. The failure to develop,
or license on acceptable
 
                                       11
<PAGE>   15
 
terms, a substitute technology could have a material adverse effect on the
Company's business, financial condition and results of operations. See
"Business -- Intellectual Property."
 
     POTENTIAL ACQUISITIONS.  In the normal course of its business, the Company
evaluates potential acquisitions of businesses, products and technologies that
could complement or expand the Company's business. In the event the Company were
to identify an appropriate acquisition candidate, there is no assurance that the
Company would be able to successfully negotiate the terms of any such
acquisition, finance such acquisition and integrate such acquired business,
products or technologies into the Company's existing business and operations.
Furthermore, the integration of an acquired business could cause a diversion of
management time and resources. In addition, there can be no assurance that any
acquisition of new technology will lead to the successful development of new
products, or that any such new products, if developed, will achieve market
acceptance or prove to be profitable. There can be no assurance that a given
acquisition, when consummated, would not materially adversely affect the
Company's business, financial condition or results of operations. If the Company
proceeds with one or more significant acquisitions in which the consideration
consists of cash, a substantial portion of the Company's available cash
(including the net proceeds of the Offering) could be used to consummate the
acquisitions. If the Company consummates one or more significant acquisitions in
which the consideration consists of stock, or is financed with the net proceeds
of the issuance of stock, stockholders of the Company could suffer a significant
dilution of their interests in the Company. See "Use of Proceeds."
 
     TAX AUDIT.  On December 12, 1997, the Internal Revenue Service ("IRS")
concluded an audit of the Company's tax returns for the years ended June 30,
1992 through June 30, 1995, and issued a formal report reflecting proposed
adjustments with respect to the years under audit. The proposed IRS adjustments
primarily relate to the disallowance of research and experimental tax credits
claimed by the Company, as well as the treatment of certain other items. The
total deficiency attributable to the proposed adjustments is $4.2 million,
including penalties and interest of $1.6 million through the date of the report.
The Company is in the process of responding to this report by appealing the
proposed adjustments to the Appeals Division of the IRS. While the Company does
not believe that the final outcome of the IRS audit will have a material adverse
effect on the Company's financial condition or results of operations, no
assurance can be given as to the final outcome of the audit, the amount of any
final adjustments or the potential impact of such adjustments on the Company's
financial condition or results of operations.
 
     YEAR 2000 COMPLIANCE.  The Company uses a significant number of computer
software programs and operating systems in its internal operations, including
applications used in manufacturing, product development, financial business
systems and various administrative functions. To the extent that these software
applications contain source code that is unable to appropriately interpret the
upcoming calendar year "2000," some level of modification or even possibly
replacement of such source code or applications will be necessary. The Company
is still in the preliminary stages of analyzing its software applications and,
to the extent they are not fully "Year 2000" compliant, there can be no
assurance that the costs necessary to update software, or potential systems
interruptions, would not have a material adverse effect on the Company's
business, financial condition or results of operations.
 
     SIGNIFICANT INFLUENCE BY EXISTING STOCKHOLDERS.  Upon completion of the
Offering, the current officers, directors and their affiliates and five percent
beneficial owners will beneficially own approximately 32.3% of the outstanding
shares of the Common Stock of the Company (30.9% if the Underwriters'
over-allotment options are exercised in full). Accordingly, such persons, if
they act together, likely will have significant influence over the Company
through their ability to control the election of directors and all other matters
that require action by the Company's stockholders, irrespective of how other
stockholders may vote. Such persons will have the ability to exert significant
influence over the business, policies and affairs of the Company and could
prevent or delay a change in control of the Company, which may be favored by a
majority of the remaining stockholders. The ability to prevent or delay a change
in control of the Company also may have an adverse effect on the market price of
the Common Stock. Under the Massachusetts General Laws, the current officers,
directors and their affiliates and five percent beneficial owners will not have
the ability to block a business combination. More specifically, such persons
will not have the requisite percentage of shares of the Company, acting alone as
a group, to (i) give a bidder the power to vote its shares at any stockholders'
meeting, including a meeting
 
                                       12
<PAGE>   16
 
to consider a bid, in accordance with Chapter 110D of the Massachusetts General
Laws, or (ii) to approve or ratify a business combination with an interested
stockholder in accordance with Chapter 110F of the Massachusetts General Laws
(as such terms are defined therein). See "Management -- Executive Officers and
Directors," "Principal and Selling Stockholders" and "Description of Capital
Stock."
 
     NO PRIOR PUBLIC MARKET; POSSIBLE VOLATILITY OF STOCK PRICE.  Prior to the
Offering, there has been no public market for the Common Stock, and there can be
no assurance that an active trading market for the Common Stock will develop or,
if developed, be sustained upon completion of the Offering. The initial public
offering price will be determined by negotiations between the Company and the
representatives of the Underwriters based on a number of factors, including
prevailing market conditions, market valuations of other companies engaged in
activities similar to those of the Company, estimates of the business potential
and prospects of the Company, the present state of the Company's business
operations, the Company's management and other factors deemed relevant. The
trading price of the Common Stock could also be subject to significant
fluctuations in response to variations in quarterly results of operations,
announcements of new products by the Company or its competitors, developments or
disputes with respect to proprietary rights, general trends in the industry,
overall market conditions, changes in earnings estimates by analysts and other
factors. In addition, the stock market historically has experienced extreme
price and volume fluctuations, which have particularly affected the market price
of securities of many high technology companies and which at times have been
unrelated or disproportionate to the operating performance of such companies.
These market fluctuations may adversely affect the market price of the Common
Stock. See "Underwriting."
 
     SHARES ELIGIBLE FOR FUTURE SALE.  Upon completion of the Offering, the
Company will have a total of 9,864,023 shares of Common Stock outstanding. Of
these shares, the 3,500,000 shares of Common Stock offered hereby (4,025,000
shares if the Underwriters' over-allotment options are exercised in full) will
be freely tradeable without restriction or registration under the Securities Act
by persons other than "affiliates" of the Company, as defined under the
Securities Act of 1933, as amended (the "Securities Act"). The remaining shares
of Common stock outstanding will be "restricted securities" as defined by Rule
144 promulgated under the Securities Act. Upon completion of the Offering, the
Company will have options outstanding to purchase 1,102,124 shares of Common
Stock. In addition, options for the purchase of 244,166 shares will remain
available for issuance under the Company's Stock Option Plans, assuming no
exercise of options after October 31, 1997. See "Management -- Stock Option
Plans" and "Shares Eligible for Future Sale."
 
   
     Under Rule 144 (and subject to the conditions thereof, including volume
limitations) all 6,364,023 restricted shares (6,069,673 restricted shares if the
Underwriters' over-allotment options are exercised in full) will become eligible
for sale after the Offering. The Company, its executive officers and directors,
the Selling Stockholders and certain other stockholders have agreed that,
subject to certain exceptions, they will not, without the prior written consent
of Prudential Securities Incorporated, on behalf of the Underwriters, directly
or indirectly, offer, sell, offer to sell, contract to sell, pledge, grant any
option to purchase or otherwise sell or dispose (or announce any offer, sale,
offer of sale, contract of sale, pledge, grant of any option to purchase or
other sale or disposition) of any shares of Common Stock or any other securities
convertible into, or exercisable or exchangeable for, shares of Common Stock or
other similar securities of the Company for a period of 180 days from the date
of this Prospectus. After such 180-day period, this restriction will expire and
shares permitted to be sold under Rule 144 would be eligible for sale, provided
that the Company shall have been subject to the reporting requirements of the
Exchange Act for at least 90 days and the relevant holding period under Rule 144
shall have expired. Prudential Securities Incorporated may, in its sole
discretion, at any time and without prior notice, release all or any portion of
the shares of Common Stock subject to such agreements. No predictions can be
made of the effect, if any, that the sale or availability for sale of additional
shares of Common Stock will have on the market price of the Common Stock.
Nevertheless, sales of substantial amounts of such shares in the public market,
or the perception that such sales could occur, could materially and adversely
affect the market price of the Common Stock and could impair the Company's
future ability to raise capital through an offering of its equity securities.
See "Shares Eligible for Future Sale."
    
 
     ANTI-TAKEOVER PROVISIONS; POSSIBLE ISSUANCE OF PREFERRED STOCK.  Certain
provisions of the Company's Restated Articles of Organization (the "Charter")
and Amended and Restated Bylaws (the "Bylaws") and certain provisions of
Massachusetts law could have the effect of making it more difficult for a third
party to
 
                                       13
<PAGE>   17
 
acquire, or of discouraging a third party from attempting to acquire, control of
the Company. Such provisions could limit the price that investors might be
willing to pay in the future for the Company's Common Stock. These provisions
permit the issuance of "blank check" preferred stock by the Board of Directors
without stockholder approval, require super-majority approval to amend certain
provisions in the Charter and Bylaws and impose various procedural and other
requirements that could make it more difficult for Stockholders to effect
certain corporate actions. In addition, the Company is subject to Chapters 110D
and 110F of the Massachusetts General Laws, which prohibit the Company 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
became 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 Company at the time he becomes an interested stockholder or
(iii) the business combination is approved by both the Company's board of
directors and two-thirds of the outstanding voting stock of the Company
(excluding shares held by the interested stockholder) at an annual or special
meeting of stockholders, and not by written consent. The application of such
provisions also could have the effect of delaying or preventing a change of
control in the Company. The Board of Directors is divided into three "staggered"
classes, with each class serving for a term of three years. Dividing the Board
of Directors in this manner increases the difficulty of removing incumbent
members and could discourage a proxy contest or the acquisition of a substantial
block of the Company's Common Stock. See "Description of Capital Stock --
Certain Articles of Organization, Bylaws and Statutory Provisions Affecting
Stockholders" and "Management."
 
     IMMEDIATE AND SUBSTANTIAL DILUTION.  Purchasers of Common Stock in the
Offering will experience an immediate and substantial dilution in the net
tangible book value of the Common Stock of $7.20 per share based upon an assumed
initial public offering price of $13.00, the mid-point of the filing range. To
the extent outstanding options to purchase shares of the Company's Common Stock
are exercised, there will be further dilution. See "Dilution."
 
     NO PRESENT INTENTION TO PAY DIVIDENDS; RESTRICTION ON PAYMENT OF
DIVIDENDS.  The Company has never declared or paid cash dividends on its Common
Stock and intends to retain any earnings for future growth. The Company
therefore does not anticipate that any cash dividends will be declared or paid
in the foreseeable future. In addition, the Company's credit facility limits the
payment of cash dividends without the consent of the lender to fifty percent of
the Company's year-to-date net income during any fiscal year. See "Dividend
Policy."

                                USE OF PROCEEDS
 
   
     The net proceeds to the Company from the sale of the 2,000,000 shares of
Common Stock offered by the Company hereby are estimated to be $23,430,000,
assuming an initial public offering price of $13.00 per share, the mid-point of
the filing range, and after deducting the underwriting discounts and commissions
and estimated offering expenses. The Company intends to use a portion of the net
proceeds of the Offering to fund construction of an additional 91,000 square
feet of office space on vacant land adjacent to its headquarters. The Company
used internally generated funds to acquire this parcel in November 1997. The
Company anticipates that construction and development of the additional office
space will cost approximately $9.0 million, that it will break ground in April
1998 and that it will complete construction in approximately 12 months after
construction begins. Once the new office space is completed, the Company plans
to transfer the building and the underlying real estate to an unaffiliated third
party pursuant to a sale and leaseback transaction. No assurance can be made
that the cost of construction and development will not exceed such estimate, or
that the Company will be able to consummate a sale and leaseback transaction
with respect to such property. Mercury intends to use the balance of the net
proceeds for working capital and general corporate purposes. A portion of the
proceeds of the Offering may be used to pay amounts arising out of an audit by
the IRS of the Company's tax returns for the years ended June 30, 1992 through
June 30, 1995. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations -- Overview." In addition, the Company may use a
portion of the net proceeds of this Offering for acquisitions of complementary
businesses, technologies or products, although there are currently no
commitments or agreements with respect to any material acquisition. Pending such
uses, the Company intends to invest the net proceeds in short term, investment
grade, interest-bearing securities. The Company will not receive any proceeds
from the sale of shares of Common Stock by the Selling Stockholders. See
"Business -- Facilities" and "Principal and Selling Stockholders."
    
 
                                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 currently intends to retain any
earnings for future growth. In addition, the Company's credit facility limits
the payment of cash dividends without the consent of its lender to fifty percent
of the Company's year-to-date net income in any fiscal year. See "Risk
Factors -- No Present Intention to Pay Dividends; Restriction on Payment of
Dividends," "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Liquidity and Capital Resources," and Note E of Notes

     Purchasers of the Common Stock offered hereby will experience an immediate
and substantial dilution in the pro forma net tangible book value of the Common
Stock from the assumed initial public offering price. The pro forma net tangible
book value of the Company as of September 30, 1997 was $36.3 million or $4.37
per share. Pro forma net tangible book value per share is determined by dividing
the net tangible book value of the Company (tangible assets less liabilities) by
the pro forma number of shares of the Company's Common Stock outstanding and
adjusting for stock options exercisable as of September 30, 1997. Without taking
into account any changes in net tangible book value subsequent to September 30,
1997, other than to give effect to the receipt of the estimated net proceeds of
the sale of the 2,000,000 shares of Common Stock offered hereby at an assumed
initial public offering price of $13.00 per share, the mid-point of the filing
range, after deducting the underwriting discounts and commissions and estimated
offering expenses, and the application of the estimated net proceeds therefrom,
the pro forma net tangible book value of the Common Stock as of September 30,
1997 would have been $59.7 million, or $5.80 per share. This represents an
immediate and substantial dilution in pro forma net tangible book value of $7.20
per share to new investors purchasing shares in the Offering. The following
table illustrates the per share dilution as of September 30, 1997:

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion and analysis should be read in conjunction with
"Selected Consolidated Financial Data" and the Company's Consolidated Financial
Statements and Notes thereto included elsewhere in this Prospectus. Except for
the historical information contained herein, the discussions in this Prospectus
contain forward-looking statements that involve risks and uncertainties. The
Company's actual results could differ materially from those discussed herein.
Factors that could cause or contribute to such differences include, but are not
limited to, those discussed below and in the section entitled "Risk Factors" as
well as those discussed elsewhere in this Prospectus.
 
OVERVIEW
 
     Mercury designs, manufactures and markets high performance, real-time
digital signal processing computer systems that transform sensor generated data
into information which can be displayed as images for human interpretation or
subjected to additional computer analysis. These multicomputer systems are
heterogeneous and scalable, allowing them to accommodate several microprocessor
types and to scale from a few to hundreds of microprocessors within a single
system.
 
     During the past three fiscal years, the majority of the Company's revenues
has been generated from sales of its products to the defense electronics market,
generally for use in intelligence gathering electronic warfare systems. The
Company's activities in this area have focused on the proof of concept,
development and deployment of advanced military applications in radar, sonar and
airborne surveillance. Medical diagnostic imaging is the other primary market
currently served by the Company. Mercury's computer systems are embedded in MRI,
CT and PET machines. The remaining component of revenues is derived from
computer systems used in such commercial applications as baggage scanning,
seismic analysis and automatic testing equipment, and from sales of Mercury's
recently introduced SuiteFusion shared storage product and related products and
services.
 
     Mercury uses a direct sales force to sell its computer systems to the
defense electronics markets in the U.S., Japan, the United Kingdom and France.
Defense electronics sales to other countries are achieved through distributors.
The Company also uses a direct sales force to sell its computer systems to the
U.S. and international medical imaging markets. The Company uses various
distribution channels for sales of shared storage products to the broadcast and
post-production industry. The Company sells these products to OEMs, value added
re-sellers and end-users. Over the past three fiscal years, the Company has
expanded its sales force to support growing revenues and has made significant
expenditures to recruit additional technical and professional staff, to invest
in information technology and to improve the Company's financial, administrative
and management infrastructure.
 
     Revenues include amounts attributable to both products, which include
development contracts, and services such as maintenance, training and
engineering consulting. Revenues from maintenance, training and engineering
consulting services generally have not constituted a material portion of total
revenues. The Company generally records product revenues upon shipment to the
customer, provided that no significant vendor obligation exists, and accrues for
associated warranty costs at the same time. For certain development contracts,
revenues are recognized using the percentage-of-completion accounting method.
Revenues from maintenance, training and engineering consulting services are
recognized ratably over the applicable contract period or as the services are
performed.
 
     Cost of revenues includes the cost of materials, component assembly,
internal labor and related overhead. Cost of revenues also can include
engineering and other technical labor and related overhead incurred in
development and engineering consulting contracts.
 
     Gross profit as a percentage of revenues ("gross margin") varies from
period to period depending upon numerous variables including the mix of revenues
from hardware, software, development and engineering consulting contracts; the
mix of revenues among the markets served by the Company; the cost of raw
materials; the cost of outsourced services and labor costs; operational
efficiencies; actual production volume
 
                                       19
<PAGE>   23
 
compared to planned volume; and the mix of applications for which the Company's
computer systems are sold. Historically, the Company's gross margins on service
revenues have been lower than on product revenues. In addition, the Company's
gross margins from development contract revenues are typically lower than the
Company's gross margins from standard product revenues. The Company intends to
continue to enter into development contracts and anticipates that the gross
margins associated with development contract revenues will continue to be lower
than its gross margins on standard product revenues.
 
     Mercury has made significant investments in research and development in an
effort to maintain its technology leadership in digital signal processing and to
create new software products for the shared storage market. Mercury invested
$8.6 million, $9.8 million and $12.8 million in fiscal years 1995, 1996 and
1997, respectively, in development activities associated with the Company's key
technology competencies as well as in activities that are targeted at developing
new technologies and products. The Company expects research and development
expenses to continue to increase as the Company continues to develop products to
serve its markets, all of which are subject to rapidly changing technology,
frequent product performance improvements and evolving industry standards. The
ability to deliver superior technological performance on a timely and cost
effective basis is a critical factor in securing design wins for future
generations of defense electronics and medical imaging systems. Significant
research and development spending by the Company does not ensure that the
Company's computer systems will be designed into a customer's system. Because
future production orders are usually contingent upon securing a design win, the
Company's operating results may fluctuate due to either obtaining or failing to
obtain design wins for significant customer systems.
 
     On December 12, 1997, the IRS concluded an audit of the Company's tax
returns for the years ended June 30, 1992 through June 30, 1995, and issued a
formal report reflecting proposed adjustments with respect to the years under
audit. The proposed IRS adjustments primarily relate to the disallowance of
research and experimental tax credits claimed by the Company, as well as the
treatment of certain other items. The total deficiency attributable to the
proposed adjustments is $4.2 million, including penalties and interest of $1.6
million through the date of the report. The Company is in the process of
responding to this report by appealing the proposed adjustments to the Appeals
Division of the IRS. While the Company does not believe that the final outcome
of the IRS audit will have a material adverse effect on the Company's financial
condition or results of operations, no assurance can be given as to the final
outcome of the audit, the amount of any final adjustments or the potential
impact of such adjustments on the Company's financial condition or results of
operations.

Three Months Ended September 30, 1997 Compared to Three Months Ended September
30, 1996
 
     Revenues
 
     Total revenues increased 46% from $13.0 million during the three months
ended September 30, 1996 to $19.0 million during the three months ended
September 30, 1997. Revenues from defense electronics, medical imaging and other
commercial markets increased, as described below.
 
     Defense electronics revenues increased 37% from $11.0 million or 84.9% of
total revenues during the three months ended September 30, 1996 to $15.1 million
or 79.6% of total revenues during the three months ended September 30, 1997. The
increase in revenues was due primarily to increased unit demand for defense
electronics products.
 
     Medical imaging revenues increased 58% from $1.4 million or 10.8% of total
revenues during the three months ended September 30, 1996 to $2.2 million or
11.7% of total revenues during the three months ended September 30, 1997. The
increase in revenues was due primarily to the doubling of sales to the largest
medical imaging customer.
 
     Other revenues increased 190% from $569,000 or 4.4% of total revenues
during the three months ended September 30, 1996 to $1.7 million or 8.7% of
total revenues during the three months ended September 30, 1997. This increase
in other revenues was due primarily to an increase in unit demand from new and
existing customers.
 
     Cost of Revenues
 
     Cost of revenues increased 47% from $4.5 million during the three months
ended September 30, 1996 to $6.7 million during the three months ended September
30, 1997 but was consistent as a percentage of total revenues at approximately
35.0%. A decline in material costs was offset by increases in manufacturing
quality costs and costs related to development contracts.
 
     Selling, General and Administrative
 
     Selling, general and administrative expenses increased 41% from $4.7
million during the three months ended September 30, 1996 to $6.6 million during
the three months ended September 30, 1997. Selling, general and administrative
expenses as a percentage of total revenues were 36.3% during the three months
ended September 30, 1996 and 34.8% during the three months ended September 30,
1997. The increase reflects the hiring of additional sales and administrative
personnel, increased commissions and the development of the Company's financial,
administrative and management systems to support the Company's growth.
 
     Research and Development
 
     Research and development expenses, excluding capitalized software
expenditures, increased 41% from $2.4 million during the three months ended
September 30, 1996 to $3.4 million during the three months ended September 30,
1997. Research and development expenses as a percentage of total revenues were
18.4% during the three months ended September 30, 1996 and 17.8% during the
three months ended September 30, 1997. The increase in research and development
expenses reflects increased investments in the Company's core technological
competencies, as well as in new medical and shared storage technologies and
products.
 
     Income from Operations
 
     Income from operations increased 72% from $1.4 million during the three
months ended September 30, 1996 to $2.4 million during the three months ended
September 30, 1997. Included in income from operations during the three months
ended September 30, 1997 were $38,000 in revenues and approximately $700,000 in
direct expenses related to the shared storage business. These include direct
expenses from marketing and engineering activities primarily related to
compensation, trade shows and prototype development. There were no revenues or
expenses related to the shared storage business during the three months ended
September 30, 1996.

     Interest Income
 
     The Company earned $136,000 in interest income during the three months
ended September 30, 1996 and $233,000 during the three months ended September
30, 1997. The increase was due primarily to the significant increase in average
balances of cash and investments.
 
     Provision for Income Taxes
 
     The Company's provision for income taxes was $576,000 during the three
months ended September 30, 1996 and $1.1 million during the three months ended
September 30, 1997. The Company's effective tax rate increased slightly from 39%
during the three months ended September 30, 1996 to 40% during the three months
ended September 30, 1997.
 
Year Ended June 30, 1997 Compared to Year Ended June 30, 1996
 
     Revenues
 
     Total revenues increased 11% from $58.3 million during the year ended June
30, 1996 to $64.6 million during the year ended June 30, 1997. The increase was
due primarily to increased unit demand in the defense electronics business and
the introduction of shared storage hardware and software during the year ended

primarily to increased unit demand for defense electronics products.
 
     Medical imaging revenues decreased 48% from $13.3 million or 22.7% of total
revenues during the year ended June 30, 1996 to $6.9 million or 10.7% of total
revenues during the year ended June 30, 1997. The decrease in revenues was due
primarily to a reduction in product prices, discontinuation of certain products
by one customer and the acceleration of purchasing at the end of the year ended
June 30, 1996 by two of the Company's medical imaging customers.
 
     Other revenues increased 67% from $3.2 million or 5.6% of total revenues

as a percentage of total revenues decreased from 42.3% during the year ended
June 30, 1996 to 34.1% during the year ended June 30, 1997. This decrease was
due primarily to the inclusion in the year ended June 30, 1996, of a domestic
defense electronics development contract which yielded significantly lower gross
margins than the gross margins historically achieved by the Company.
 
     Selling, General and Administrative
 
     Selling, general and administrative expenses increased 34% from $16.9
million during the year ended June 30, 1996 to $22.6 million during the year
ended June 30, 1997. Selling, general and administrative expenses as a
percentage of total revenues were 29.0% during the year ended June 30, 1996 and
35.0% during the year ended June 30, 1997. The increase reflects the hiring of
additional sales and administrative personnel, increased commissions and the
development of the Company's financial and administrative systems to support the
Company's growth.
 
     Research and Development
 
     Research and development expenses, excluding capitalized software
expenditures, increased 31% from $9.8 million during the year ended June 30,

<PAGE>   26
 
June 30, 1996 and 19.9% during the year ended June 30, 1997. The increase
reflects greater investment in the Company's core competencies, as well as in
new medical and shared storage technologies and products.
 
     Income from Operations
 
     Income from operations increased 2% from $6.9 million during the year ended
June 30, 1996 to $7.1 million during the year ended June 30, 1997. Included in

hardware and software revenues and $3.6 million in direct expenses related to
the shared storage business. These include direct expenses from marketing and
engineering activities, primarily related to compensation, trade shows and
prototype development and direct costs related to the sale of the product,
including certain hardware costs. There were no revenues or expenses related to
the shared storage business during the year ended June 30, 1996.
 
     Interest Income
 
     The Company earned $561,000 in interest income during the year ended June
30, 1996 and $582,000 during the year ended June 30, 1997. This increase in
interest income was due to the increase in average balances of cash and
investments, partially offset by a decrease in average interest rates.
 
     Provision for Income Taxes
 
     The Company's provision for income taxes was $3.0 million during the year
ended June 30, 1996 and $2.9 million during the year ended June 30, 1997. The

</TABLE>
 
     The Company has experienced fluctuations in its results of operations in
large part due to the sale by the Company of its computer systems in relatively
large dollar amounts to a relatively small number of customers. Operating
results also have fluctuated due to competitive pricing programs and volume
discounts, the loss of customers, market acceptance of the Company's products,
product obsolescence and general economic conditions. In addition, the Company,
from time to time, has entered into development contracts. The Company's gross
margins from development contract revenues are typically lower than the
Company's gross margins from standard product revenues. The Company intends to
continue to enter into development
 
                                       25
<PAGE>   29
 
contracts and anticipates that its gross margins associated with development
contract revenues will continue to be lower than its gross margins on standard
product revenues.
 
     The Company's quarterly results may be subject to fluctuations resulting
from the foregoing factors, as well as a number of other factors, including the
timing of significant orders, delays in completion of internal product
development projects, delays in shipping the Company's computer systems and
software programs, delays in acceptance testing by customers, a change in the
mix of products sold to the defense electronics and medical imaging markets,
production delays due to quality problems with outsourced components, shortages
of components, the timing of product line transitions and declines in quarterly
revenues from old generations of products following announcement of replacement
products containing more advanced technology. Another factor contributing to
fluctuations in quarterly results is the fixed nature of the Company's
expenditures on personnel, facilities and marketing programs. The Company's
expense levels for personnel, facilities and marketing programs are based, in
significant part, on the Company's expectations of future revenues on a
quarterly basis. If actual quarterly revenues are below management's
expectations, results of operations likely will be adversely affected. As a
result of the foregoing factors, the Company's operating results, from time to
time, may be below the expectations of public market analysts and investors,
which could have a material adverse effect on the price of the Company's Common
Stock.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     During the past five fiscal years, the Company has funded its operations to
date primarily from cash generated from operations. As of September 30, 1997,
the Company had cash and cash equivalents of approximately $16.0 million and
working capital of $28.7 million. During the three months ended September 30,
1996, the Company generated approximately $843,000 in cash from operations
compared to $2.0 million generated during the three months ended September 30,
1997. During the year ended June 30, 1996, the Company generated approximately
$4.3 million in cash from operations compared to $9.2 million generated during
the year ended June 30, 1997. The increases in cash generated from operations
were due to improved operating results, higher percentage of non-cash expenses
within total expenses and better management of the Company's inventory and
receivables. The Company's days sales outstanding was 71 days and 58 days at
June 30, 1997 and September 30, 1997, respectively.
 
     The Company has a line of credit agreement with a commercial bank on which
the Company can borrow up to $6.0 million at an interest rate equal to the prime
rate or, at the election of the Company, two and one quarter percentage points
above the London InterBank Offered Rate. As of September 30, 1997, there was no
outstanding borrowing on this line of credit.
 
     The Company used approximately $1.4 million in investing activities for
computers, furniture and equipment during the three months ended September 30,
1997, compared to $567,000 during the three months ended September 30, 1996.
During the year ended June 30, 1997, the Company invested approximately $4.0
million, which consisted primarily of $3.5 million for the investment in
computers, furniture and equipment and $550,000 for capitalized software,
compared to $3.3 million during the year ended June 30, 1996, which consisted of
$2.9 million for computers, furniture and equipment and $371,000 for capitalized
software. No software development costs were capitalized during the three months
ended September 30, 1997.
 
   
     The Company intends to use a portion of the net proceeds of the Offering to
fund construction of additional 91,000 square feet of office space on vacant
land adjacent to its headquarters. The Company used internally generated funds
to acquire this parcel in November, 1997. The Company anticipates that
construction and development of the additional office space will cost
approximately $9.0 million, that it will break ground in April 1998 and that it
will complete construction and development in approximately 12 months after
construction begins. Once the new office space is completed, the Company plans
to transfer this parcel to an unaffiliated third party pursuant to a sale
leaseback transaction. No assurances can be made that the cost of construction
will not exceed such estimate, or that the Company will be able to consummate a
sale and leaseback transaction with respect to such property. The Company does
not expect to realize a profit or loss from the sale of the finished building.
See "Use of Proceeds" and "Business -- Facilities."
    
 
   
     A portion of the proceeds of the Offering may be used to pay amounts
arising out of an audit by the IRS of the Company's tax returns for the years
ended June 30, 1992 through June 30, 1995. Mercury believes that the net
proceeds of the Offering, together with available cash, cash generated from
operations and the
    
 
                                       26
<PAGE>   30
 
Company's line of credit, will be sufficient to provide for the Company's
working capital and capital expenditure requirements for the foreseeable future
and any final adjustments resulting from the IRS audit described above. If the
Company acquires one or more businesses or products, the Company's capital
requirements could increase substantially. In the event of such an acquisition
or in the event that any unanticipated circumstances arise which significantly
increase the Company's capital requirements, there can be no assurance that
necessary additional capital will be available on terms acceptable to the
Company, if at all.

OVERVIEW
 
     Mercury designs, manufactures and markets high performance, real-time
digital signal processing computer systems that transform sensor generated data
into information which can be displayed as images for human interpretation or
subjected to additional computer analysis. These multicomputer systems are
heterogeneous and scalable, allowing them to accommodate several different
microprocessor types and to scale from a few to hundreds of microprocessors
within a single system. Mercury's system architecture is specifically designed
for digital signal processing applications which are typically computation
intensive and require I/O capacity and interprocessor bandwidth not available on
a general purpose PC or workstation. The two primary markets for Mercury's
products are defense electronics and medical diagnostic imaging. Both of these
markets have computing needs which benefit from the unique system architecture
developed by the Company. Mercury's computer systems are generally used on real
world signal data to enable a military commander to "see" the battle space
through natural barriers such as clouds, darkness, water or foliage, so that the
position and strength of the enemy can be determined, or to enable a physician
to "see" within the body instead of performing invasive surgery.
 
     During the past three fiscal years, the majority of the Company's revenues
have been generated from sales of its products to the defense electronics
market, generally for use in intelligence gathering electronic warfare systems.
The Company's activities in this area have focused on the proof of concept,
development and deployment of advanced military applications in radar, sonar and
airborne surveillance. The Company has established relationships with many of
the major prime contractors to the worldwide defense industry, including
Lockheed Martin, Hughes Aircraft, Raytheon/E-Systems, Raytheon/TI Systems,
Northrop Grumman, MIT/Lincoln Laboratory, GEC Marconi, Ericcson, MATRA,
Mitsubishi and a prime contractor owned by the Israeli Ministry of Defense.
 
     Medical diagnostic imaging is the other primary market currently served by
the Company. Mercury's computer systems are embedded in MRI, CT and PET
machines. Mercury has supplied computer systems for use in several of GE
Medical's medical diagnostic imaging systems since 1987, and has established
relationships with Siemens Medical, Toshiba and Elscint. The major medical
imaging manufacturers are currently developing the next generation of MRI, CT
and digital x-ray machines, which are expected to provide better performance at
lower cost. Mercury has recently secured design wins on programs with certain of
the major medical imaging manufacturers for their next generation MRI, CT and
digital x-ray machines.
 
     Mercury's computer systems are designed to process continuous streams of
data from sensors attached to radar, sonar, medical imaging equipment and other
devices. The resulting image is transmitted to the battlefield commander, pilot,
technician or physician in order to assist in the decision making or diagnostic
process. Due to the nature of the applications in which many of Mercury's
computer systems are embedded, they are frequently confined in limited spaces
and therefore are designed to generate a minimum amount of heat. The Company
employs the RACEway Interconnect, an industry standard system area network
developed by Mercury, which allows for high interprocessor bandwidth and I/O
capacity. The Company uses its proprietary ASICs to integrate microprocessors,
memory and related components into the RACEway Interconnect to provide optimum
system performance. The Company uses industry standard processors, such as
Intel's i860, Motorola's PowerPC, Texas Instruments' C80 and Analog Devices'
SHARC, in the same system. The Company believes that the RACEway Interconnect
and its proprietary ASICs, working together with a group of mixed
microprocessors in the same system, allow the most efficient use of space and
power with an optimal price/performance ratio.
 
     Since July 1996, Mercury has targeted the emerging shared storage market
for introduction of a new product which draws on the Company's core competencies
in systems engineering and the development of real-time software. In fiscal
1997, Mercury introduced SuiteFusion, its first shared storage product designed
to meet the needs of the broadcast and post-production industry. SuiteFusion is
an open, scalable software application that allows work groups to share
commodity, fibre channel attached disk arrays, eliminating the need for an
expensive, intermediate file server. Early end-users include Turner
Broadcasting's CNN
 
                                       28
<PAGE>   32
 
Interactive, Nickelodeon's Blue's Clues television show and Hughes Aircraft
(through a subsidiary) for use at the U.S. Army National Training Center. The
Company believes that the shared storage market includes a number of distinct
applications, such as digital video editing, electronic computer aided design,
webcasting, cable advertising insertion and pre-press.
 
INDUSTRY BACKGROUND
 
  Defense Electronics
 
     Digital signal processing computer systems are embedded into air, sea and
land-based platforms for processing radar, sonar and signal intelligence
applications. These applications allow a military commander to "see" the battle
space through natural barriers such as clouds, darkness, water or foliage, so
that the position and strength of the enemy can be determined. The Electronic
Industry Association (the "EIA") in its October 1997 annual forecast of the
defense electronics market predicted an increase in military electronics
purchases over the next ten years, while predicting a decline in total defense
spending over the same period. The EIA also predicted that, beginning in 1998,
United States military spending on electronics and information systems will
increase by $7.4 billion from $51.5 billion to $58.9 billion over the next ten
years. The Company believes that an important factor underlying this anticipated
growth is a continuing desire by military commanders for increased battle space
information, which can be obtained through radar, sonar, signal intelligence and
image intelligence systems. Military commanders also need more powerful
computers with similar attributes in order to conduct battle simulations and
mission planning tasks utilizing today's complex weapons systems.
 
     Another important trend in the defense electronics marketplace is the
movement away from so-called "stove pipe" systems designed by prime contractors
with special purpose hardware specifically for a single application, largely
without regard to cost. The market is moving toward the use of systems which
incorporate selected COTS hardware and software components in order to save
money and development time. Recent Department of Defense ("DoD") leaders and
federal regulations have mandated widespread use of COTS components in defense
electronics applications. All of Mercury's computer systems are eligible for use
in defense electronics applications as COTS components.
 
  Medical Imaging
 
     The principal modalities of medical diagnostic imaging systems include MRI,
CT, digital x-ray, PET, SPECT (single photon emission computed tomography) and
ultrasound devices. The Company believes that the available market in 1998 for
digital signal processing computer systems in the aggregate for the MRI, CT and
digital x-ray markets is expected to be an aggregate of approximately $123.0
million. Although demand for medical imaging equipment has been sluggish in
recent years due primarily to cost containment pressures and consolidation in
the health care industry, the Company believes that demand for medical
diagnostic imaging equipment will increase modestly over the next three years.
The Company believes that this increase will be primarily due to the
introduction of next generation devices, together with the anticipated future
development by the major medical imaging manufacturers of new markets for their
diagnostic equipment in countries located in Asia, South America and Eastern
Europe. The Company believes medical imaging equipment manufacturers will
continue to replace in-house designed digital signal processing systems with
commercially available systems designed by the Company and others.
 
     This industry's demand is driven in part by the need to provide physicians
with rapid, sharp and clear images of areas of a patient's body suspected to be
diseased or injured, while using the least intrusive means. These images provide
a significant diagnostic tool for the physician, who can more readily understand
the patient's malady and prescribe appropriate corrective action. In order to
provide such images, medical imaging machines must be capable of processing a
continuous stream of data on a real-time basis. A parallel concern in the health
care industry is the need to reduce costs. Hospitals, in particular, continue to
be under significant pressure to contain costs and, at the same time, maintain
quality of care. Such pressures are forcing hospitals to be as technologically
efficient as possible. Toward this end, hospitals seek to reduce the required
period of time a patient must spend in its medical imaging machines, which has
the added benefit of increasing the total number of patients who can be
diagnosed with this expensive equipment during a given period of time. One
 
                                       29
<PAGE>   33
 
way to reduce patient time in medical imaging machines and improve image quality
is to utilize more powerful signal processing computers, such as those supplied
by Mercury.
 
STRATEGY
 
     Mercury's objective is to be the leader in each of its markets by
developing and delivering architecturally superior systems, developing and
maintaining close working relationships with its customers, adopting and
deploying total quality management and extending key technology competencies to
new markets where Mercury can provide solutions based on its core competencies.
 
     Develop and Deliver Architecturally Superior Systems.  Mercury intends to
continue to develop architecturally superior systems comprised of both hardware
and software commercially available off-the-shelf components, which minimize
recurring and non-recurring costs, as well as proprietary components, which
enable production of standards-based, highly scalable systems. The Company's
growth and leadership in its primary markets has been due in part to investments
in a sustainable architecture that can rapidly evolve to take advantage of the
latest developments in semiconductor technology. Rapid evolution is accomplished
by defining a set of building blocks that can evolve separately. In this way the
architecture can be refreshed by upgrading one hardware and/or software building
block (such as a new microprocessor) with only minimal effect, if any, to the
other building blocks.
 
     Develop and Maintain Close Working Relationships with Customers.  By
developing close working relationships with its customers, the Company intends
to continue to identify and pursue new product opportunities. To fulfill these
opportunities, the Company frequently develops variations of its standard
products pursuant to contracts with particular customers in order to satisfy the
customers' needs on a cost effective basis.
 
     Adopt and Deploy Total Quality Management.  The Company is deploying Total
Quality Management ("TQM") as an overarching managerial approach to improve and
enhance business processes within the Company. An integral part of TQM is
increasing the Company's ability to discover and understand customers' unique
needs in the context of their environments and to set benchmarked performance
targets for each customer. By implementing TQM, the Company expects to be able
to enhance its development process and deliver better value by responding to
customer specific needs. When fully deployed, the Company believes that TQM will
significantly enhance its business processes and competitiveness.
 
     Extend Key Technology Competencies to New Markets.  The Company is
constantly seeking new markets where solutions can be provided based on its core
competencies. The Company's entry into the shared storage market evolved from
Mercury's work in real time operating systems, and its systems engineering skill
set in solving bandwidth limitations for applications requiring extremely high
data throughput. The Company initially targeted its new software product,
SuiteFusion, to meet the shared storage needs of the broadcast and
post-production industry. Mercury is currently evaluating other opportunities in
the shared storage market, such as electronic computer aided design, webcasting,
cable advertising insertion and pre-press.

     Mercury's computer systems have been or are being integrated into various
programs in the defense electronics market. For example, Mercury is under
contract to supply, or has supplied, computer systems to the following
contractors:
 
     -  Northrop Grumman for use in the tactical endurance synthetic aperture
        radar ("SAR") systems aboard the Predator, a medium-altitude unmanned
        aerial vehicle ("UAV") which has been deployed in Bosnia.
 
     -  Northrop Grumman for the SAR systems on board the Dark Star high
        altitude UAV, which is currently under development.
 
     -  Hughes Aircraft for the SAR systems on the Global Hawk high altitude
        endurance UAV, which is currently under development.
 
     -  Raytheon/E-Systems for the delivery of computer systems (including
        development systems) for use in an electronic signal intelligence
        application on board the RC-135 aircraft as part of an upgrade program.
 
     -  Raytheon/TI Systems for the delivery of computer systems (including
        development systems) for use in the SAR on board the P3 Orion
        anti-submarine surveillance aircraft as part of an upgrade program.
 
     -  Lockheed Martin, the U.S. Army Research Laboratory and FOA, the Swedish
        defense research institute, for proof of concept in foliage and/or
        ground penetrating radars.
 
     -  Lockheed Martin for use in the development, integration and testing of
        the sonar subsystem for the New Attack Submarine and Atlantic Aerospace
        Electronics Corporation for the combat sonar system used in the Los
        Angeles Class submarine, which are currently under development.
 
     -  Northrop Grumman/ESSD and MIT/Lincoln Laboratory for use in developing
        algorithms for space time adaptive processing, a type of advanced radar
        system. The prototype computer system for this application uses
        approximately 1,000 microprocessors, and Mercury believes it is the most
        powerful commercial real-time embedded computer ever built, with peak
        performance in excess of 100 gigaflops.
 
     -  Ericsson for the use of Mercury's standard commercial processors in
        radar systems on board surveillance aircraft and to build MILSPEC
        versions for the radar system on the SAAB Gripen fighter aircraft.
 
     Mercury employs industry specialist managers to monitor the defense
programs of each major branch of the United States armed services and additional
managers based in Europe and Japan to keep abreast of developments in their
respective regions. This approach provides relevant information to Mercury
regarding major military procurements worldwide. Mercury maintains sales and
technical support groups to service defense industry participants in six branch
offices in the United States, and through Mercury's subsidiary offices or
distributors in 12 other countries. At Mercury's headquarters in Chelmsford,
Massachusetts, a group of systems engineers specializing in radar, sonar and
surveillance problems provides support on an as-needed basis to the remote
offices to assist in securing inclusion in targeted military programs.
 
  Medical Imaging
 
     Mercury strives to provide a superior combination of high performance and
competitively priced embedded computer systems to the medical imaging market.
The Company focuses on establishing strong relationships with its customers, the
medical equipment manufacturers. By maintaining frequent, in-depth
communications with its customers and working closely with their engineering
groups, the Company is able to understand their needs and provide appropriate
solutions. In addition, the Company intends to continue its efforts to install
its computer systems in place of alternative designs created by the in-house
design teams employed by the medical imaging equipment manufacturers.
 
     The Company currently is working closely with major medical equipment
companies to design the next generation of MRI, CT and digital x-ray systems,
which the Company believes will lead to faster time-to-market and competitive
advantages for the medical equipment companies that use Mercury's computer
 
                                       32
<PAGE>   36
 
systems for inclusion in their imaging machines. Mercury's industrial PC class
hardware system provides the medical imaging industry with increased performance
densities at lower costs and an architecture that accommodates performance
upgrades as new technology becomes available. Integrating the high-bandwidth
RACEway Interconnect system area network within the PCI environment results in
highly scalable systems. This allows medical equipment suppliers to design
systems that can satisfy a broad range of price/performance requirements and
meet the needs of global markets, all with the same Mercury architecture.
 
     Mercury's medical OEM customers consist of the leading manufacturers of
diagnostic imaging equipment. They include GE Medical, headquartered in
Wisconsin, GE Medical Systems Europe in France, GE Yokugawa Medical Systems in
Japan, Toshiba in Japan, Siemens Medical in Germany and Elscint in Israel. These
companies have adopted Mercury's PCI or VME computer systems as part of their
developments in either MRI, CT, PET or digital x-ray systems and, in the case of
some companies, multiple types of systems. The Company has supplied GE Medical
with computer systems for use in three successive generations of MRI machines
from 1987 through the present, as well as for use in other GE Medical equipment,
such as PET. In addition, GE Medical and Siemens Medical, the two leading global
suppliers of medical imaging equipment, have recently awarded contracts to
Mercury to design the signal processing system for the next generations of
certain of their medical diagnostic equipment.
 
     The Company is building a system based on Analog Devices' SHARC DSP
processor to fulfill a design win in CT. The Company also is building a system
based on the Texas Instruments' C80 signal processing chip to fulfill a design
win in digital x-ray. The Company believes that the principal reason for its
medical imaging design wins is Mercury's experienced team of systems and
applications engineers who work closely with the medical equipment designers and
with the Company's product development engineers. This joint design effort
frequently precedes the first production orders by approximately two to three
years. However, once selected, the production contracts typically continue for
the life of the medical imaging system. In addition, the equipment manufacturers
typically offer computer system upgrades to their customers, potentially
resulting in additional sales of Mercury products.
 
  Shared Storage
 
     The Company believes that the shared storage market includes a number of
distinct applications, such as digital video editing, electronic computer aided
design, webcasting, cable advertising insertion and pre-press. In fiscal 1997,
Mercury introduced SuiteFusion, its first shared storage software product
designed to meet the digital video editing needs of the broadcast and
post-production industry. Companies in the broadcast and post-production
industry have begun to use non-linear, disk-based technology, and are becoming
aware of the significant productivity gains that can be achieved by networking
multiple editing stations together in a real-time, high-bandwidth, shared
storage workgroup. However, these applications produce extremely large volumes
of digital data that must be transmitted, stored, and manipulated in order to
produce a high-quality finished product. Mercury's SuiteFusion is designed to
choreograph the interactions between workstations and disks to keep files intact
in such a high-performance, shared-storage environment.
 
     Early end-users of SuiteFusion include Turner Broadcasting's CNN
Interactive in Atlanta, Georgia, Hughes Aircraft (through a subsidiary), for use
at the U.S. Army National Training Center in Fort Irwin, California, and
Nickelodeon's Blue's Clues television show in New York, New York. CNN is using
Mercury's software to improve efficiency in editing and producing features for
Internet broadcasts; the U.S. Army uses SuiteFusion to help capture, edit and
play back live simultaneous training exercises; and Nickelodeon's creative
design artists are able to share animation and graphics files.
 
     In addition, Mercury has signed OEM distribution agreements with several
industry leaders, including Avid Technology, Inc., the worldwide leader in
digital non-linear editing systems, PathLight in the serial storage architecture
networking environment, and MountainGate Data Systems, Inc. in the fiber channel
storage market. The Company also has approximately 10 non-exclusive distributor
agreements with video-editing resellers in the United States and Canada.

KEY TECHNOLOGY COMPETENCIES
 
     Many of Mercury's customers share a common requirement: the need to process
high-volume, real-time data streams. Whether from an antenna in a defense
application, a medical scanner or a video camera, the computer must have the
ability to process incoming data as quickly as it is received. Data rates can
range from a few to several hundreds of megabytes per second (or several billion
bits per second). The ability to process this continuous flow of high-bandwidth
data is a fundamental difference between the majority of computing systems in
the world (such as personal computers, workstations and servers) and the
computers built by Mercury.
 
     Mercury has developed a set of core technical strengths specifically
targeted to, and defined by, the application areas of signal, image and media
processing. These technical strengths are pivotal to Mercury's success in the
real-time market segments of the defense electronics and medical imaging
industries and have resulted in the following developments and capabilities:
 
     Heterogeneous Switched-Fabric Interconnects.  Mercury connects different
microprocessor types (RISC, DSP and specialized computing devices) and I/O
devices in a bus-less, high-bandwidth manner based on multi-stage switches in
its system area network. Among the engineering developments which distinguish
Mercury's systems are the RACEway Interconnect built using the six-port RACEway
crossbar chip which supports high bandwidth point-to-point data transfers and
fibre channel chassis-to-chassis extensions for RACEway in large system
configurations.
 
     Heterogeneous Processor Integration.  Mercury has developed several ASICs
which integrate standard microprocessors and special purpose mathematics and
graphics processors into a single heterogenous environment. Mercury develops
systems consisting of different microprocessor types with a single-system
software model. Mercury's processor independent software offers a consistent set
of software tools and interfaces, which can drive a heterogeneous mix of
microprocessor types, such as Motorola's PowerPC processor, Analog Devices'
SHARC DSP processor and Texas Instruments' C80 processor.
 
     Performance Density.  The Company has been using high performance packaging
technology such as multi-chip modules and ball grid arrays in its systems since
the early 1990's. The Company's thermal analysis expertise allows it to design
products that optimize the dissipation of heat from the system in order to meet
the environmental constraints imposed by many of its customers' applications.
The Company's modular hardware and software building blocks allow it to design
systems that best meet the application's specific data profiles. All together,
these attributes combine to deliver the maximum performance in processing,
reliability and bandwidth in the smallest possible space.
 
     Scalable Software.  Mercury's software has been designed to scale to more
than one thousand processors in real-time environments while maintaining a
high-bandwidth capability. Regardless of the number of processors, the Company's
software provides the same programming environment for a software developer
working with Mercury's computer systems, allowing faster time-to-market and
lower life cycle maintenance costs for its customers.
 
     Optimized Algorithm Development.  Mercury specializes in algorithm
development for single and multi-processor implementations. The Company believes
that using the mathematical algorithms in Mercury's scientific algorithm library
significantly increases the performance of customers' applications, reduces
development time and minimizes life cycle support costs.
 
     System Engineering Expertise.  Mercury has established a core competency in
providing total system solutions to its customers. The Company has the knowledge
and technical staff to act as an extension of the customer's engineering
organization in order to fashion solutions to some of the world's most demanding
real-time, signal processing applications. Mercury has partnered with its
customers to understand and resolve the challenging problems encountered in
applications as diverse as radar, sonar and signal intelligence for the
military, and diagnostic imaging for MRI, CT, PET and digital x-ray in the
medical imaging market. The Company also provides an integration and development
service to meet the demands of its customers with advanced applications which
cannot be satisfied with standard products. This service combines the variety of
 
                                       34
<PAGE>   38
 
standard products with custom hardware and software to meet the specific
configuration demands of an application.
 
     Leverage and Create Standards.  Mercury uses existing standards where
applicable and has been successful in developing new standards. For example,
Mercury adheres to VME and PCI standard bus interfaces and form factors. The
RACEway Interconnect system area network that Mercury developed was adopted as
an ANSI/VITA standard in 1995, and since then has been adopted by several
companies offering products and services for embedded real-time applications.
 
PRODUCTS
 
HARDWARE PRODUCTS
 
     Mercury offers three classes of systems for the Company's target markets.
Each class of products is scalable to meet the full range of requirements in
signal processing applications.
 
     High Performance Class.  For the highest-performance applications, Mercury
offers a family of high performance systems for the most compute intensive and
I/O capacity and interprocessor bandwidth demanding applications in the defense
electronics market. These applications include space time adaptive processing,
ground-penetrating and foliage-penetrating radar and synthetic aperture radar.
These high-performance systems, known as MultiPort, can scale to over a thousand
processors and today include compute modules based on the SHARC and PowerPC
processors.
 
     VME Class.  The VME bus has been the traditional standard for many embedded
applications. Mercury's VME systems each have a RACEway Interconnect port.
Systems contain modules based on the SHARC, PowerPC and i860 processors and can
scale to several hundred processors. The VME-based systems and components are
primarily used in the defense market where backward and forward compatibility is
required for the long system life cycles of military equipment. This class of
RACE Series systems meets the computing speed, bandwidth and scaleability
requirements of many of today's medium performance radar, sonar and signal
intelligence applications. Advanced and future radar systems are more likely to
use the high performance class systems.
 
     Industrial PC Class.  Based on the PCI bus standard, these systems use the
RACEway Interconnect to provide the extended bandwidth required for real-time
applications. Currently Mercury provides compute modules based on the SHARC and
TI C80 processors. These systems scale to hundreds of processors and are
primarily directed to the medical imaging market, which is moving from VME to
PCI based designs.
 
SOFTWARE PRODUCTS
 
     Mercury has developed a comprehensive line of signal processing software
products for the defense and medical imaging markets. Certain of Mercury's
software products are included in a heterogeneous development software package
that enables customers to develop application software that will run on Mercury
hardware. The development software package includes the MC/OS operating system,
scientific algorithm libraries, debugging tools and compilers. License fees
range from $10,000 to $50,000 based on the number of seats chosen by the user
for its application, ranging from a single user license to a project license.
 
     Set forth below are certain signal processing software products offered by
the Company.
 
     MC/OS Version 4.  The MC/OS runtime operating environment allows maximum
use of the RACE heterogeneous multi-computer architecture in a single-system
model incorporating a consistent set of system and application programming
interfaces, and a common development environment. MC/OS is supported on the high
performance, VME and industrial PC classes of Mercury hardware systems. MC/OS is
included in Mercury's development software package.
 
     Scientific Algorithm Library (SAL).  Mercury's scientific algorithm library
consists of more than 400 assembly language routines developed by Mercury's
programmers and optimized for execution on Mercury's RACE architecture,
permitting extensive code reusability. The library encompasses a comprehensive
selection
 
                                       35
<PAGE>   39
 
of functions including vector processing and data conversion commonly performed
by digital signal processing applications. SAL is included in Mercury's
development software package.
 
     Parallel Application System (PAS).  PAS is a set of high performance
libraries which form a complete programming environment for developing parallel
applications in a distributed memory multicomputer system. The libraries speed
the development of advanced applications using many processors in parallel. PAS
is included in Mercury's development software package.
 
     SuperVision.  SuperVision is a state-of-the-art debugging tool for
observation and control of embedded, real-time multicomputing systems.
SuperVision speeds application development by selectively monitoring individual
and large groups of processors, while simultaneously performing detailed
process-level debugging. SuperVision is sold separately.
 
     PeakWare for RACE.  PeakWare for RACE is a visual component programming
tool, jointly developed with MATRA, that allows the developer to use diagrams to
express the interconnection of software components. Jointly mapping the
application and the RACE system configuration accelerates the overall
development process. From the graphical input, PeakWare for RACE generates the C
code for interprocessor communication and builds executable and ready-to-deploy
application code. PeakWare for RACE is sold separately.
 
     Mercury also has developed software products for specific shared storage
applications in the broadcast and post-production industry. Set forth below is
the first such software product commercially introduced by the Company.
 
     SuiteFusion.  SuiteFusion is an open, scalable software application that
allows various desktop computer systems to simultaneously access large shared
files. Written in JAVA, this highly portable code is supported on both Macintosh
and Windows-based PC desktops. While SuiteFusion is directed initially to the
creative and design departments within the broadcast and post-production
industry, the Company believes it has potential applicability in several shared
storage markets.
 
ENGINEERING, RESEARCH AND DEVELOPMENT
 
     The Company's engineering, research and development efforts are focused on
developing new products as well as enhancing existing products. Mercury's
research and development goal is to fully exploit and maintain the Company's
technological lead in the high performance, real-time, signal processing
industry. In addition to the central engineering organization which focuses on
Mercury's two principal markets, the Company has an engineering team developing
SuiteFusion and its derivatives for the shared storage market and another
engineering team developing systems for the digital television requirements of
the future.
 
     Mercury is involved with researchers from other companies and government
organizations to develop new signaling technologies using fiber optics. This has
the potential for providing more bandwidth per line than conventional techniques
and is directed at the 21(st) century challenges of the next generation of
advanced signal processing systems. Similar cooperative developments are
underway to develop open software solutions for code portability. This research
is focused on developing generic applications which can be targeted to Mercury's
products through the use of industry standard tools with Mercury-specific
libraries. Some of these research areas benefit from cost sharing through DARPA
grants in those areas where the DoD will obtain benefit from the development.
 
     As of September 30, 1997, the Company had 32% of all its employees, or 104
people, primarily engaged in engineering, research and development, including
hardware and software architects, design engineers and engineers with expertise
in developing medical, defense and shared storage software systems. During
fiscal years 1995, 1996 and 1997, the Company's total research and development
costs were approximately $8.6 million, $9.8 million, and $12.8 million,
respectively.
 
CUSTOMER SUPPORT AND INTEGRATION
 
     As of September 30, 1997, Mercury's Customer Services Group included 37
people engaged in a full range of support functions, including training,
technical program management, integration and design services,
 
                                       36
<PAGE>   40
 
host porting services and the traditional maintenance and support services. The
Company has invested in the range of tools, analyzers, simulators, instruments
and workstations to provide a rapid response to both development and customer
support requirements. Within the Customer Services Group, the solutions systems
department has developed many custom interfaces, reviewed customers' designs,
developed special hardware and software components and provided program
management on behalf of defense and medical customers. The capabilities of this
group enable the Company to respond to the demanding individuality of many
programs and have resulted in Mercury being selected for both development, high
volume production and deployed programs.
 
MANUFACTURING AND TESTING
 
     Mercury's strengths include the design, development and testing of products
which meet the exacting technology and quality expectations of the Company's
defense electronics and medical imaging customers. Board assembly is outsourced
to a number of electronic contract manufacturers. The supplier typically inserts
most of the components into a printed circuit board, solders the connections,
conducts preliminary testing and returns the boards to Mercury. The Company
conducts final assembly, burn-in and system level testing.
 
     Mercury utilizes Optimal Supply Chain Management to provide highly flexible
manufacturing solutions which can be tailored to the specific needs of the
Company's customers, while maintaining the highest level of quality and control
of product assembly. This standard is maintained through demanding Quality
Assurance and Reliability Programs, such as Statistical Process Control, which
are integrated throughout the manufacturing process.
 
     The Company's outsourcing strategy provides maximum flexibility to respond
to customer requirements and schedule adjustments, with minimal asset investment
by Mercury. This outsourcing strategy also provides multiple sources of supply,
both to support the breadth and complexity of Mercury's product lines, as well
as to ensure continuity of supply. By outsourcing assembly to electronic
contract manufacturers, Mercury is able to focus its manufacturing efforts on
designing more reliable products, designing more efficient methods of building
its products, systems integration, testing and supply chain management.
 
     Mercury's manufacturing approach is based on a highly integrated process
that takes a product from concept through production. All products are required
to meet specified standards of performance, quality, reliability and safety. The
Company manufactures both commercial and ruggedized versions of its computer
systems. Extensive testing is a fundamental part of the Company's process.
Computer Integrated Manufacturing, Concurrent Engineering, Material Requirements
Planning and Just-In-Time techniques are also integrated into manufacturing
operations as part of an on-time delivery philosophy. Mercury has been ISO 9001
certified since 1995.
 
     Several components used in the Company's products are currently obtained
from sole source suppliers. Mercury is dependent on LSI Logic for four custom
designed ASICs, on Analog Devices for its SHARC processors, on IBM for ball grid
array packaging, on Motorola for its PowerPC processors and on Intel for its
i860 processors. IBM may terminate its contract with the Company without cause
upon thirty days notice and may cease offering products to the Company upon
sixty days notice. In addition, Analog Devices may discontinue or modify any
product upon 180 days notice and LSI Logic may discontinue any product upon 180
days notice. If LSI Logic, Analog Devices, IBM, Motorola or Intel were to limit
or reduce the sale of such components to the Company, or if these or other
suppliers to the Company were to experience financial difficulties or other
problems which prevented them from supplying the Company with the necessary
components, such events could have a material adverse effect on the Company's
business, financial condition and results of operations. These sole source
suppliers are subject to quality and performance issues, materials shortages,
excess demand, reduction in capacity and other factors that may disrupt the flow
of goods to the Company or its customers and thereby adversely affect the
Company's business and customer relationships. The Company has no guaranteed
supply arrangements with its suppliers and there can be no assurance that its
suppliers will continue to meet the Company's requirements. If the Company's
supply arrangements are interrupted, there can be no assurance that the Company
would be able to find another supplier on a timely or satisfactory basis. Any
shortage or interruption in the supply of any of the components used in the
Company's
 
                                       37
<PAGE>   41
 
products, or the inability of the Company to procure these components from
alternate sources on acceptable terms could have a material adverse effect on
the Company's business, financial condition and results of operations. There can
be no assurance that severe shortages of components will not occur in the
future. Such shortages could increase the cost or delay the shipment of the
Company's products, which could have a material adverse effect on the Company's
business, financial condition and results of operations. Significant increases
in the prices of these components would also materially adversely affect the
Company's financial performance since the Company may not be able to adjust
product pricing to reflect the increase in component costs. The Company could
incur set-up costs and delays in manufacturing should it become necessary to
replace any key vendors due to work stoppages, shipping delays, financial
difficulties or other factors and, under certain circumstances, these costs and
delays could have a material adverse effect on the Company's business, financial
condition and results of operations.
 
COMPETITION
 
     The markets for the Company's products are highly competitive and are
characterized by rapidly changing technology, frequent product performance
improvements and evolving industry standards. Competition typically occurs at
the design stage, where the customer evaluates alternative design approaches,
including those from internal development organizations. A design win usually
ensures a customer will purchase the product until their next generation system
is developed. Occasionally, the Company's computer systems compete with computer
systems from workstation vendors, all of whom have substantially greater
research and development resources, long term guaranteed supply capacity,
marketing and financial resources, manufacturing capability and customer support
organizations than those of the Company. The Company believes that its future
ability to compete effectively will depend, in part, upon its ability to
continue to improve product and process technologies and develop new
technologies in order to maintain the performance advantages of products and
processes relative to competitors, to adapt products and processes to
technological changes, to identify and adopt emerging industry standards and to
adapt to customer needs.
 
     The principal bases for selection in sales of digital signal processing
systems to the defense electronics industry are performance (measured primarily
in terms of processing speed, I/O capacity and interprocessor bandwidth,
processing density per cubic foot, power consumption and heat dissipation),
systems engineering support, overall quality of products and associated
services, use of industry standards, ease of use and price. Competitors in the
defense electronics industry include a relatively small number of companies that
design, manufacture and market DSP board level products and in-house design
teams employed by prime defense contractors. In-house design efforts
historically have provided a significant amount of competition to the Company.
However, competition from in-house design teams has diminished in significance
in recent years due to the increasing use of COTS products and the trend toward
greater use of outsourcing. Despite this recent change, there can be no
assurance that in-house developments will not re-emerge as a major competitive
force in the future. Prime contractors are much larger than Mercury and have
substantially more resources to invest in research and development. Increased
use of in-house design teams by defense contractors in the future may have a
material adverse effect on the Company's business, financial condition and
results of operations.
 
     In the medical imaging industry the principal bases for selection are
performance (measured primarily in terms of processing speed, I/O capacity and
interprocessor bandwidth and power consumption), price, systems engineering
support, overall quality of products and associated services, use of industry
standards and ease of use. Competitors in the medical imaging market include
in-house design teams, a small number of companies that design, manufacture and
market DSP board level products and workstation manufacturers. Workstations have
become a competitive factor primarily in the market for low-end MRI and CT
machines and, to date, have not been a significant factor in the
high-performance market, Mercury's primary focus. There can be no assurance that
workstation manufacturers will not attempt to penetrate the high-performance
market for medical imaging machines. Workstation manufacturers typically have
greater resources than Mercury and their entry into markets historically
targeted by Mercury may have a material adverse effect on the Company's
business, financial condition and results of operations.
 
     Due to the emerging nature of the markets for the Company's shared storage
technology, its competitive factors are not yet clearly defined. The Company
currently is focusing its efforts in this area on the broadcast
 
                                       38
<PAGE>   42
 
and post-production industry, where the Company believes there is currently only
one directly competitive product. As this market develops, the Company
anticipates that other companies will begin offering additional competitive
products. New competitors may have significantly greater marketing and financial
resources, better access to individuals making purchasing decisions, superior
products and services than those offered by the Company. The Company believes
that the primary impediment to future sales of shared storage products to the
post-production and broadcast industry is the need to transform entrenched
operating modes, such as those associated with linear tape based technologies,
to accommodate new modes of operation such as those associated with non-linear,
disk-based digital technology. However, there can be no assurance that industry
participants will adopt such new technologies or that, if adopted, the Company's
products will not be obsolete, uncompetitive or incompatible.
 
     Some of the Company's competitors have greater financial and other
resources than the Company, and the Company may be operating at a cost
disadvantage compared to manufacturers who have greater direct buying power from
component suppliers or who have lower cost structures. There can be no assurance
that the Company will be able to compete successfully in the future with any of
these sources of competition. In addition, there can be no assurance that
competitive pressures will not result in price erosion, reduced margins, loss of
market share or other factors, that could have a material adverse effect on the
Company's business, financial condition and results of operations.
 
INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS
 
     The Company relies on a combination of patent, copyright, trademark and
trade secret laws to establish and protect its rights in its products and
proprietary technology. In addition, the Company currently requires its
employees and consultants to enter into nondisclosure and assignment of
invention agreements to limit use of, access to and distribution of, proprietary
information. There can be no assurance that the Company's means of protecting
its proprietary rights in the U.S. or abroad will be adequate. The laws of some
foreign countries may not protect the Company's proprietary rights as fully or
in the same manner as do the laws of the U.S. Also, despite the steps taken by
the Company to protect its proprietary rights, it may be possible for
unauthorized third parties to copy or reverse engineer aspects of the Company's
products, develop similar technology independently or otherwise obtain and use
information that the Company regards as proprietary. There can be no assurance
that others will not develop technologies similar or superior to the Company's
technology or design around the proprietary rights owned by the Company.
Although the Company is not aware that its products infringe on the proprietary
rights of third parties, there can be no assurance that others will not assert
claims of infringement in the future or that, if made, such claims will not be
successful. Litigation to determine the validity of any claims, whether or not
such litigation is determined in favor of the Company, could result in
significant expense to the Company and divert the efforts of the Company's
technical and management personnel from daily operations. In the event of any
adverse ruling in any litigation regarding intellectual property, the Company
may be required to pay substantial damages, discontinue the sale of infringing
products, expend significant resources to develop non-infringing technology or
obtain licenses to use infringing or substituted technology. The failure to
develop, or license on acceptable terms, a substitute technology could have a
material adverse effect on the Company's business, financial condition and
results of operations.
 
     The Company holds two issued United States patents covering aspects of the
RACE architecture and the SuperVision debugging tool. In addition, the Company
has two pending United States patent applications covering additional aspects of
the RACE architecture and the Company's Parallel Application System. The Company
may file additional patent applications seeking protection for other proprietary
aspects of its technology in the future. Patent positions frequently are
uncertain and involve complex and evolving legal and factual questions. The
coverage sought in a patent application either can be denied or significantly
reduced before or after the patent is issued. Consequently, there can be no
assurance that any patents from pending patent applications or from any future
patent application will be issued, that the scope of any patent protection will
exclude competitors or provide competitive advantages to the Company, that any
of the Company's patents will be held valid if subsequently challenged or that
others will not claim rights in or ownership of the patents and other
proprietary rights held by the Company. Since patent applications are secret
until patents are issued in the United States or corresponding applications are
published in international countries, and
 
                                       39

since publication of discoveries in the scientific or patent literature often
lags behind actual discoveries, the Company cannot be certain that it was the
first to make the inventions covered by each of its pending patent applications
or that it was the first to file patent applications for such inventions. In
addition, there can be no assurance that competitors, many of which have
substantial resources and have made substantial investments in competing
technologies, will not seek to apply for and obtain patents that will prevent,
limit or interfere with the Company's ability to make, use or sell its products
either in the United States or in international markets.
 
BACKLOG
 
     As of September 30, 1997, the Company had a backlog of orders aggregating
approximately $25.7 million. The Company includes in its backlog customer orders
for products and services for which it has accepted signed purchase orders with
assigned delivery dates within twelve months. Orders included in backlog may be
canceled or rescheduled by customers without penalty. 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
previously made or anticipated. The Company cannot assure the timely replacement
of canceled, delayed or reduced orders. Significant or numerous cancellations,
reductions or delays in orders by a customer or group of customers could
materially adversely affect the Company's business, financial condition and
results of operations. Backlog should not be relied upon as indicative of the
Company's revenues for any future period.
 
EMPLOYEES
 
     At September 30, 1997, the Company employed a total of 323 persons,
including 104 in research and development, 120 in sales, marketing and customer
support, 51 in manufacturing and 48 in finance and administration. Eight of the
Company's employees are located in Europe, four in Japan and the remainder in
the U.S. None of the Company's employees are represented by a labor organization
and the Company believes that its relations with employees are good. Competition
for qualified personnel in the engineering fields is intense and the Company is
aware that much of its future success will depend on its continued ability to
attract and retain qualified personnel. The Company seeks to attract new
employees by offering competitive compensation packages, including salary,
bonus, stock options and employee benefits. There can be no assurance, however,
that the Company will be successful in retaining its key employees or that it
will be able to attract skilled personnel for the development of its business.
 
FACILITIES
 
     The Company's headquarters consist of approximately 96,000 square feet of
office space under lease in Chelmsford, Massachusetts. The Company intends to
use a portion of the net proceeds of the Offering to fund construction of
additional 91,000 square feet of office space on vacant land adjacent to its
headquarters. The Company used internally generated funds to acquire this parcel
in November 1997. The Company anticipates that construction and development of
the additional office space will cost approximately $9.0 million, that it will
break ground in April 1998 and that it will complete construction in
approximately 12 months after construction begins. Once the new office space is
completed, the Company plans to transfer the building and the underlying real
estate to an unaffiliated third party pursuant to a sale and leaseback
transaction. The Company has not yet identified a counterparty for this sale and
leaseback transaction. While the Company believes it should be able to identify
such a party within a reasonably limited period of time, there can be no
assurance that the Company will be able to successfully consummate such
transaction on commercially acceptable terms, if at all. If the Company is not
able to successfully consummate a sale and leaseback transaction, the Company
would retain this property and would not have use of the money invested therein.
See "Use of Proceeds."
 
     The Company also maintains offices near Los Angeles and San Jose,
California, and in Dallas, Texas, Chanhassen, Minnesota, Madison, Wisconsin and
Vienna, Virginia and has international offices in the United Kingdom, France and
Japan.
 
LEGAL PROCEEDINGS
 
     To the Company's knowledge, there are no pending legal proceedings which
are material to the Company or its business to which it is a party or to which
any of its properties is subject.

(1) In accordance with the rules of the Securities and Exchange Commission (the

(1) Value is based on the difference between the option exercise price and the
    assumed initial public offering price of $13.00 per share, the mid-point of
    the filing range, multiplied by the number of shares of Common Stock
    underlying the option. No market existed for the Common Stock prior to this

STOCK OPTION AND STOCK PURCHASE PLANS
 
  Stock Option Plans
 
     The Company has in effect its 1997 Stock Option Plan (the "1997 Plan"),
1993 Stock Option Plan for Non-Employee Directors (the "1993 Plan"), 1991 Stock
Option Plan (the "1991 Plan") and 1982 Stock Option Plan (the "1982 Plan," and
with the 1997 Plan, the 1993 Plan and the 1991 Plan, the "Stock Option Plans").
The Company's stock option plans are designed to attract, retain and motivate
key employees and directors. The Compensation Committee of the Board of
Directors (the "Compensation Committee") is responsible for the administration
and interpretation of the Stock Option Plans and is authorized to grant options
thereunder to all eligible employees and directors of the Company, except that
no director who is not also an employee of the Company is eligible to receive
incentive stock options (as defined in Section 422 of the Internal Revenue Code)
("Incentive Options") and only directors who are not employees of the Company
are eligible to receive options under the 1993 Plan. The Compensation Committee
has full power to select, from among the persons eligible for awards under the
1982 Plan, the 1991 Plan and the 1997 Plan, the individuals to whom awards will
be granted, to make any combination of awards to participants, and to determine
the specific terms of each award, subject to the provisions of the Stock Option
Plans. Under the 1993 Plan, each non-employee director of the Company received
on or about September 30 in each of 1994, 1995, 1996 and 1997, and will receive
on or about September 30, 1998, that number of shares of Common Stock equal to
one percent of the net income of the Company for the most recent fiscal year
ending prior to the grant divided by the per share fair market value of the
Company Stock on the first day of such fiscal year divided by the number of
non-employee directors in office at the time of the grant. Options granted under
the Stock Option Plans vest and become exercisable in accordance with option
agreements evidencing such grants. Incentive Options may be granted only to
officers or other employees of the Company, including members of the Board of
Directors who are also employees of the Company or its subsidiaries. Options
which do not qualify as Incentive Options, "Non-Qualified Options" may be
granted or issued to officers or other employees of the Company, directors and
to consultants and other key persons who provide services to the Company
(regardless of whether they are also employees).
 
     The exercise price of each option granted under the Stock Option Plans is
determined by the Compensation Committee but, in the case of Incentive Options,
may not be less than 100% of the fair market value of the underlying shares on
the date of grant. No Incentive Option may be granted under the Stock Option
Plans to any employee of the Company or any subsidiary who owns at the date of
grant shares of stock representing in excess of 10% of the combined voting power
of all classes of stock of the Company or a parent or a subsidiary unless the
exercise price for stock subject to such option is at least 110% of the fair
market value of such stock at the time of grant and the option term does not
exceed five years.
 
                                       46
<PAGE>   50
 
     Options may be made exercisable in installments, and the exercisability of
options may be accelerated by the Compensation Committee. Upon exercise of
options, the option exercise price must be paid in full (i) in cash or by
certified or bank check or other instrument acceptable to the Compensation
Committee, (ii) if the applicable option agreement permits, by delivery of
shares of Common Stock of the Company owned by the optionee having a fair market
value equal in amount to the exercise price of the options being exercised or
(iii) any combination of (i) and (ii), provided, however that payment of the
exercise price by delivery of shares of Common Stock of the Company owned by
such optionee may be made only to the extent such payment, in whole or in part,
would not result in a charge to earnings for financial accounting purposes.
 
     As of October 31, 1997, options to purchase 342,601 shares of Common Stock
were outstanding under the 1997 Plan, of which 19,175 were then exercisable. As
of October 31, 1997, options to purchase 32,482 shares of Common Stock were
outstanding under the 1993 Plan, all of which were then exercisable. As of
October 31, 1997 options to purchase 579,090 shares of Common Stock were
outstanding under the 1991 Plan, of which options to purchase 267,910 shares
were then exercisable. As of October 31, 1997, options to purchase 142,200
shares of Common Stock were outstanding under the 1982 Plan, all of which were
then exercisable.
 
     Options granted under the Company's stock option plans are not transferable
by the optionee except by will, by the laws of descent and distribution or
pursuant to a qualified domestic relations order. Options are exercisable only
while the optionee remains in the employ of the Company or for a short period of
time thereafter. Options which are exercisable following termination of
employment are exercisable only to the extent that the optionee was entitled to
exercise such options on the date of termination of his or her employment.
 
   
     Under the 1997 Plan, 575,000 shares were reserved for issuance upon
exercise of stock options as of October 31, 1997. Under the Company's 1993 Plan,
50,000 shares of Common Stock were reserved for exercise upon exercise of stock
options as of October 31, 1997. Under the 1991 Plan, 700,000 shares of Common
Stock were reserved for exercise upon exercise of stock options as of October
31, 1997. Under the Company's 1982 Stock Option Plan, 144,700 shares were
reserved for issuance upon exercise of stock options as of October 31, 1997.
    
 
  Employee Stock Purchase Plan
 
     The Company's 1997 Employee Stock Purchase Plan (the "1997 Purchase Plan")
for employees of the Company was adopted by the Board of Directors on November
6, 1997 and will be submitted by the Stockholders of the Company for approval at
a Special Meeting of Stockholders to be held on December 18, 1997. The 1997
Purchase Plan authorizes the issuance of a maximum of 250,000 shares of Common
Stock pursuant to the exercise of nontransferable options granted to
participating employees.
 
     The 1997 Purchase Plan is administered by the Compensation Committee. All
employees of the Company whose customary employment is 20 hours or more per week
and have been employed by the Company for at least six months are eligible to
participate in the 1997 Purchase Plan. Employees who own 5% or more of the
Company's stock and directors who are not employees of the Company may not
participate in the 1997 Purchase Plan. To participate in the 1997 Purchase Plan
an employee must authorize the Company in writing to deduct an amount (not less
than 1% nor more than 10% of a participant's base compensation not to exceed
$25,000 per year) from his or her pay commencing on January 1 and July 1, of
each year (each a "Purchase Period"). On the first day of each Purchase Period,
the Company grants to each participating employee an option to purchase up to
that number of shares of Common Stock, the fair market value of which on the
date of grant is equal to $25,000. The exercise price for the option for each
Purchase Period is the lesser of 85% of the fair market value of the Common
Stock on the first or last business day of the Purchase Period. The fair market
value will be the closing selling price of the Common Stock as quoted on the
Nasdaq National Market. If an employee is not a participant on the last day of
the Purchase Period, such employee is not entitled to exercise his or her
option, and the amount of his or her accumulated payroll deduction will be
refunded to the employee. Shares acquired by employees pursuant to the Purchase
Plan may not be transferred for three months following the date of acquisition.

Plan terminate upon his or her voluntary withdrawal from the Plan at any time or
upon termination of employment.
 
     Common Stock for the 1997 Purchase Plan will be made available either from
authorized but unissued shares of Common Stock or from shares of Common Stock
reacquired by the Company, including shares repurchased in the open market.
 
LIMITATION OF LIABILITY; INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     As permitted by the Massachusetts General Laws, the Company has included in
its Charter a provision to eliminate the personal liability of its directors for
monetary damages for breach or alleged breach of their fiduciary duties as
directors, subject to certain exceptions. In addition, the Bylaws of the Company
provide that the Company is required to indemnify its officers and directors
under certain circumstances, including those circumstances in which
indemnification would otherwise be discretionary, and the Company is required to
advance expenses to its officers and directors as incurred in connection with
proceedings against them for which they may be indemnified. At present, the
Company is not aware of any pending or threatened litigation or proceeding
involving a director, officer, employee or agent of the Company in which
indemnification would be required or permitted. The Company believes that its
Charter provisions and indemnification agreements are necessary to attract and
retain qualified persons as directors and officers. Insofar as indemnification
for liabilities arising under the Securities Act may be permitted to directors,
officers and controlling persons of the Company pursuant to the foregoing, the
Company has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable.
 
                              CERTAIN TRANSACTIONS
 
     The Company has loaned James R. Bertelli, President of the Company, an
aggregate of $200,000, of which $150,000 accrues interest at an annual rate of
9.75% and $50,000 accrues interest at an annual rate of 10.5%. In addition, the
Company has loaned Albert Belle Isle, a Director of the Company, an aggregate of
$125,000, of which $100,000 accrues interest at an annual interest rate of 8%
and $25,000 accrues interest at 9.25%. The notes evidencing such obligations of
Mr. Bertelli and Dr. Belle Isle are payable in full on the earlier of December
31, 1999, or 181 days following the consummation of an initial public offering
of the Company's Common Stock.
 
     The Company has granted Memorial Drive Trust, Mr. Bertelli, President and
Chief Executive Officer of the Company, and certain other stockholders certain
rights with respect to the registration of the Company's securities. See
"Description of Capital Stock -- Registration Rights of Certain Holders."

                          DESCRIPTION OF CAPITAL STOCK
 
     Effective upon the closing of the Offering, the Company's authorized
capital stock will consist of 25,000,000 shares of Common Stock and 1,000,000
shares of Preferred Stock, par value $.01 per share and will have 9,864,023
shares of Common Stock outstanding, assuming no exercise of options after
October 31, 1997. As of October 31, 1997, an aggregate of 5,307,231 shares of
Common Stock were held of record by 148 stockholders, and 852,264 shares of
Preferred Stock were outstanding and held of record by three stockholders. All
shares of Preferred Stock will be converted into Common Stock upon the
completion of this offering at the rate of three shares of Common Stock for each
share of Preferred Stock. Copies of the Charter and Bylaws have been filed as
exhibits to the Registration Statement and are incorporated by reference herein.
 
COMMON STOCK
 
     All outstanding shares of Common Stock are, and the Common Stock offered
hereby will be, fully paid and nonassessable. The holders of Common Stock are
entitled to one vote for each share held of record on all matters voted upon by
Stockholders and may not cumulate votes. Subject to the rights of holders of any
future series of undesignated preferred stock which may be designated, each
share of the outstanding Common Stock is entitled to participate equally in any
distribution of net assets made to the Stockholders in the liquidation,
dissolution or winding up of the Company and is entitled to participate equally
in dividends as and when declared by the Board of Directors. There are no
redemption, sinking fund, conversion or preemptive rights with respect to the
shares of Common Stock. All shares of Common Stock have equal rights and
preferences.
 
PREFERRED STOCK
 
     Upon the completion of this Offering, all of the outstanding Preferred
Stock will be converted into Common Stock. After the completion of this
Offering, the Board of Directors will have the authority, without further
stockholder approval, to issue 1,000,000 shares of preferred stock where defined
in one or more series and to fix the relative rights, preferences, privileges,
qualifications, limitations and restrictions thereof, including dividend rights,
dividend rates, conversion rights, voting rights, terms of redemption,
redemption prices, liquidation preferences and the number of shares constituting
any series or the designation of such series. The issuance of preferred stock,
while potentially providing desirable flexibility in connection with possible
acquisitions and other corporate purposes, could have the effect of delaying,
deferring or preventing a change in control of the Company, may discourage bids
for the Common Stock at a premium over the market price of the Common Stock and
may adversely affect the market price of, and the voting and other rights of the
holders of the Common Stock. No shares of preferred stock will be outstanding
immediately following the completion of this Offering. The Company has no
present plans to issue any shares of Preferred Stock. See "Risk
Factors -- Anti-takeover Provisions; Possible Issuance of Preferred Stock."
 
REGISTRATION RIGHTS OF CERTAIN HOLDERS
 
     The holders of 6,505,264 shares of Common Stock (the "Registrable
Securities") or their transferees are entitled to certain rights with respect to
the registration of such shares under the Securities Act. These rights are
provided under the terms of certain agreements, by and among the Company and the
holders of the Registrable Securities. No shares being registered for the
account of Selling Stockholders are being registered pursuant to these
registration rights. Upon consummation of the Offering and subject to certain
limitations in the applicable agreements, holders of 5,078,794 shares of
Registrable Securities may request registration under the Securities Act of all
or part of their Registrable Securities, six months after the effective date of
the Offering. If the Company registers any of its Common Stock either for its
own account or for the account of other security holders, the holders of
5,078,794 shares of Registerable Securities are entitled to include their shares
of Common Stock in the registration, subject to pro rata cutback. All
registration expenses must be borne by the Company and all selling expenses
relating to Registrable Securities must be borne by the holders of the
securities being registered. In addition, certain holders of Registrable
Securities may request registration under the Securities Act of all or part of
their Registrable Securities on Form S-3 if use of such form becomes available
to the Company.

     Pursuant to a Stock Purchase Agreement, dated as of January 20, 1984, among
the Company and certain of its stockholders, (i) Memorial Drive Trust and other
investors (together, the "Investors") purchased an aggregate of 852,264 shares
of the Company's Series A Convertible Preferred Stock for an aggregate
consideration of $1,200,000; and (ii) the Investors received so-called "demand"
registration rights, and the Investors, James R. Bertelli, a director and
President of the Company, Gordon Baty, a director of the Company, and certain
other stockholders of the Company received so-called "piggyback" registration
rights.
 
     Pursuant to a Debenture Agreements, dated December 21, 1987, between the
Company and each of Massachusetts Mutual Life Insurance Company and MassMutual
Corporate Investors (together "Massachusetts Mutual"), Massachusetts Mutual
received so-called "demand" and "piggyback" registration rights. Under these
Debenture Agreements, the Company sold to Massachusetts Mutual $3,000,000 in
principal amount of convertible debentures. On March 1, 1993, these debentures
were converted into 1,000,000 shares of Common Stock which are covered by the
registration rights described above.
 
     No predictions can be made as to the effect, if any, that future sales of
shares, or the availability of shares for future sales, will have on the
prevailing market price for the Common Stock. Sales of substantial amounts of
Common Stock, or the perception that such sales could occur, could adversely
affect prevailing market prices for the Common Stock and could impair the
Company's future ability to obtain capital through an offering of equity
securities. See "Risk Factors -- Shares Eligible for Future Sale."
 
CERTAIN ARTICLES OF ORGANIZATION, BYLAWS AND STATUTORY PROVISIONS AFFECTING
STOCKHOLDERS
 
     Classified Board and Other Matters.  The Board of Directors will be divided
into three classes, each of which, after a transitional period, will serve until
the third annual meeting of stockholders after their election, with one class
being elected each year. Since the classification of directors has already been
established, investors purchasing Common Stock in the Offering will not have an
opportunity to vote on the classification. Under the Massachusetts General Laws,
in the case of a corporation having a classified Board, Stockholders may remove
a director only for cause. The Bylaws require that stockholders provide the
Clerk of the Company 60 days advance notice prior to the date set forth in the
Bylaws for an annual meeting of Stockholders or special meeting in lieu thereof
for the purpose of any director nominations or within ten (10) days notice after
notice of a special meeting not in lieu of annual meeting. The Bylaws provide
that special meetings of stockholders of the Company may be called only by the
Board of Directors, the President or 30% in interest of the stockholders. The
Bylaws as well as applicable provisions of the Massachusetts General Laws,
provide that no action required or permitted to be taken at any annual or
special meeting of the stockholders of the Company may be taken without a
meeting, unless the unanimous consent of stockholders entitled to vote thereon
is obtained. The affirmative vote of the holders of at least 80% of the combined
voting power of then outstanding voting stock of the Company will be required to
alter, amend or repeal the foregoing provisions; provided, however, that if any
proposal to alter any of the foregoing provisions receives the affirmative vote
of a majority of the directors, then such proposal shall require only the
affirmative vote of the holders of a majority of the outstanding voting stock of
the Company. Such supermajority voting provisions diminish the likelihood that a
potential acquiror would make an offer for the Common Stock, impede a
transaction favorable to the interest of the stockholders or increase the
difficulty of removing a number of Board of Directors or management. See "Risk
Factors -- Anti-Takeover Provisions; Possible Issuance of Preferred Stock."
 
     Chapters 110D and 110F of Massachusetts General Laws.  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) at an annual or special meeting of stockholders, not by
written consent. An interested stockholder is a person who, together with
affiliates and associates, owns 5% or
 
                                       52
<PAGE>   56
 
more of the Corporation's outstanding voting stock or who is an affiliate at any
time within the prior three years did own 5% or more of the corporation's voting
stock. Voting control obtained by means of a revocable proxy will not trigger
the implications of Chapter 110F of the Massachusetts General Laws. 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 Bylaws 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."
This statute provides, in general, 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. Voting
control obtained by means of a revocable proxy will not trigger the implications
of Chapter 110D of the Massachusetts General Laws. In addition, Chapter 110D
permits a corporation to provide in its articles of organization or bylaws 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 Charter includes a provision which permits the Company to effect
such redemptions. See "Risk Factors."
 
     Directors Liability.  The Charter provides that no director shall be
personally liable to the Company or its stockholders for monetary damages for
breach of fiduciary duty as a director, except for (i) any breach of the
directors's duty of loyalty to the Company or its Stockholders; (ii) acts or
omissions which has been adjudicated not to be in good faith or to have involved
intentional misconduct; (iii) acts covered by Massachusetts General Laws,
Chapter 156B, Section 61, which imposes personal liability upon directors voting
for distributions to stockholders which are prohibited by a company's Articles
of Organization or for which a company has insufficient funds to make legally;
(iv) acts covered by Massachusetts General Laws, Chapter 156B, Section 62, which
imposes personal liability for directors in the event Company loans to its
officers and directors are not repaid; or (v) any transaction from which such
director derives improper personal benefit. The effect of this provision is to
eliminate the rights of the Company and its stockholders (through stockholders'
derivative suits on behalf of the Company) to recover monetary damages against a
director for breach of the fiduciary duty of care as a director (including
breaches resulting from negligent or grossly negligent behavior) except in the
situations described in clauses (i) through (iv) above. The limitations
summarized above, however, do not affect the ability of the Company or its
stockholders to seek non-monetary based remedies, such as an injunction or
rescission, against a director for breach of his fiduciary duty nor would such
limitations limit liability under the federal securities laws. The Bylaws
provide that the Company shall, to the full extent permitted by the
Massachusetts General Laws as currently in effect, indemnify and advance
expenses to each of its currently acting and former directors, officers,
employees and agents arising in connection with their acting in such capacities.
 
TRANSFER AGENT AND REGISTRAR
 
   
     Boston EquiServe Limited Partnership will serve as the transfer agent and
registrar for the Common Stock.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion of the Offering, the Company will have outstanding
9,864,023 shares of Common Stock, assuming no exercise of options after October
31, 1997. Of these shares, the 3,500,000 shares offered hereby (4,025,000 shares
if the Underwriters' over-allotment options are exercised in full) will be
freely tradeable without restriction or further registration under the
Securities Act, unless purchased by "affiliates" of the Company as that term is
defined in Rule 144 described below. The remaining 6,364,023 shares of Common
Stock (6,069,673 shares if the Underwriters' over-allotment options are
exercised in full) outstanding upon closing of the Offering are "restricted
securities" as that term is defined in Rule 144. Of the remaining 6,364,023
shares (6,069,673 shares if the Underwriters' over-allotment options are
exercised in full), 6,024,578 shares are subject to lock-up agreements
(described below).
 
     Upon completion of the Offering, 2,231,063 shares, including shares subject
to the lock-up restrictions described below, will become eligible for immediate
sale pursuant to Rule 144(k) and, beginning 90 days after commencement of the
Offering, an additional 4,107,809 shares, including shares subject to the
lock-up restrictions described below, will become eligible for sale pursuant to
Rule 144 or Rule 701 under the Securities Act ("Rule 701"). The 25,250 remaining
shares held by existing stockholders will become eligible for sale at various
times over a period of less than one year. In addition, 463,517 shares of Common
Stock subject to outstanding vested stock options could also be sold, subject in
some cases to compliance with certain volume limitations as described below.
Upon expiration of the lock-up agreements, an aggregate of 2,127,266 shares will
become immediately eligible for sale without restriction pursuant to Rule 144(k)
or Rule 701 (described below), and approximately 3,924,311 additional shares
will be eligible for sale subject to the timing, volume, and manner of sale
restrictions of Rule 144.
 
     In general, under Rule 144, as recently amended, a person (or persons whose
shares are aggregated) who has beneficially owned shares for at least one year
(including the holding period of any prior owner except an affiliate from whom
such shares were purchased) is entitled to sell in "brokers' transactions" or to
market makers, within any three-month period commencing 90 days after the date
of this Prospectus, a number of shares that does not exceed the greater of (i)
one percent of the number of shares of Common Stock then outstanding
(approximately 98,640 shares immediately after the completion of the Offering)
or (ii) generally, the average weekly trading volume in the Common Stock during
the four calendar weeks preceding the required filing of a Form 144 with respect
to such sale. Sales under Rule 144 are subject to the availability of current
public information about the Company. Under Rule 144(k), a person who is not
deemed to have been an affiliate of the Company at any time during the 90 days
preceding a sale, and who has beneficially owned the shares proposed to be sold
for at least two years (including the holding period of any prior owner other
than an affiliate from whom such shares were purchased), is entitled to sell
such shares without having to comply with the manner of sale, public
information, volume limitation or notice provisions of Rule 144. Under Rule 701,
persons who purchase shares upon exercise of options granted prior to the
effective date of the Offering are entitled to sell such shares 90 days after
the effective date of the Offering in reliance on the resale provisions of Rule
701, which are similar to the resale provisions of Rule 144, except such persons
do not have to comply with the holding period requirements of Rule 144 and, in
the case of non-affiliates, such persons do not have to comply with the public
information, volume limitation or notice provisions of Rule 144.
 
   
     Pursuant to the lock-up agreements, the Company, its executive officers and
directors, the Selling Stockholders and certain other stockholders have agreed
that, subject to certain limited exceptions, they will not, without the prior
written consent of Prudential Securities Incorporated, on behalf of the
Underwriters, directly or indirectly, offer, sell, offer to sell, contract to
sell, pledge, grant any option to purchase or otherwise sell or dispose (or
announce any offer, sale, offer of sale, contract of sale, pledge, grant of any
option to purchase or other sale or disposition) of any shares of Common Stock
or any securities convertible into, or exercisable or exchangeable for, any
shares of Common Stock, or other similar securities of the Company for a period
of 180 days from the date of this Prospectus, except that such agreements do not
prevent the Company from granting additional options under the Stock Option
Plans or from issuing shares pursuant to the 1997 Purchase Plan. After such 180
day period, this restriction will expire and shares permitted to be sold under
Rule 144 will be eligible for sale. Prudential Securities Incorporated may, in
its sole discretion, at any time and
    
 
                                       54
<PAGE>   58
 
without prior notice, release all or any portion of the shares of Common Stock
subject to such lock-up agreements.
 
     The holders of an aggregate of 6,505,264 shares of Common Stock or their
transferees are entitled to certain rights with respect to the registration of
such shares under the Securities Act. See "Description of Capital
Stock -- Registration Rights of Certain Holders."
 
     The Company currently intends to file one or more registration statements
on Form S-8 with the Commission in order to register the 1,719,700 shares of
Common Stock subject to the Stock Option Plans and the 1997 Purchase Plan.
 
     Prior to the Offering, there has not been any public market for the Common
Stock. Future sales of substantial amounts of Common Stock in the public market
could adversely affect the prevailing market prices and impair the Company's
ability to raise capital through the sale of equity securities.

</TABLE>
 
     The Company and the Selling Stockholders 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 Selling Stockholders that they propose to offer the shares of Common
Stock initially at the public offering price set forth on the cover page of this
Prospectus; that the Underwriters may reallow to selected dealers a concession
of $          per share; and that such dealers may reallow a concession of
$          per share to certain other dealers. After the initial public
offering, the offering price and the concessions may be changed by the
Representatives.
 
     The Company and certain Selling Stockholders have granted to the
Underwriters over-allotment options, exercisable for 30 days from the date of
this Prospectus, to purchase, in the aggregate, up to 525,000 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 options solely for the purpose of covering
over-allotments incurred in the sale of the shares of Common Stock offered
hereby. To the extent such options to purchase are 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 Underwriter's name in the preceding table bears to 3,500,000.
 
     The Company and the Selling Stockholders have agreed to indemnify the
several Underwriters and contribute to any losses arising out of certain
liabilities, including liabilities under the Securities Act.
 
     The Representatives have informed the Company and the Selling Stockholders
that the Underwriters do not intend to confirm sales to any accounts over which
they exercise discretionary authority.
 
   
     The Company, its executive officers and directors and certain Stockholders,
including the Selling Stockholders, have agreed that, subject to certain limited
exceptions, they will not, for a period of 180 days subsequent to the date of
this Prospectus, directly or indirectly, offer, sell, offer to sell, contract to
sell, pledge, grant any option to purchase or otherwise sell or dispose (or
announce any offer, sale, offer of sale, contract of sale, pledge, grant of any
option to purchase or other sale or disposition) of any shares of Common Stock
or securities substantially similar thereto, or any securities convertible into
or exercisable or exchangeable for,
    
 
                                       56
<PAGE>   60
 
any shares of Common Stock or securities substantially similar thereto of the
Company without the prior written consent of Prudential Securities Incorporated,
on behalf of the Underwriters, except that such agreements do not prevent the
Company from granting additional options under the Stock Option Plan. Further,
certain holders of outstanding vested stock options are subject to 180 day
lock-up agreements with the Company and/or Prudential Securities Incorporated.
Prudential Securities Incorporated may in its sole discretion at any time and
without notice, release all or any portion of the securities subject to such
lock-up agreements.
 
     Prior to the Offering, there has been no public market for the Common Stock
of the Company. Consequently, the initial public offering price will be
determined through negotiations between the Company and the Representatives.
Among the factors to be considered in making such determination will be the
prevailing market conditions, the Company's financial and operating history and
condition, its prospects and the prospects for its industry in general, the
management of the Company and the market prices of securities for companies in
businesses similar to that of the Company.
 
     In connection with the Offering, certain Underwriters and selling group
members (if any) and their respective affiliates may engage in transactions that
stabilize, maintain or otherwise affect the market price of the Common Stock.
Such transactions may include stabilization transactions effected in accordance
with Rule 104 of Regulation M, pursuant to which such persons may bid for or
purchase Common Stock for the purpose of stabilizing its market price. The
Underwriters also may create a short position for the account of the
Underwriters by selling more Common Stock in connection with the Offering than
they are committed to purchase from the Company and the Selling Stockholders,
and in such case may purchase Common Stock in the open market following the
closing of the Offering to cover all or a portion of such short position. The
Underwriters may also cover all or a portion of such short position, up to
525,000 shares of Common Stock, by exercising the Underwriters' over-allotment
options referred to above. In addition, Prudential Securities Incorporated, on
behalf of the Underwriters, may impose "penalty bids" under contractual
arrangements with the Underwriters whereby it may reclaim from an Underwriter
(or dealer participating in the Offering) for the account of the other
Underwriters, the selling concession with respect to Common Stock that is
distributed in the Offering but subsequently purchased for the account of the
Underwriters in the open market. Any of the transactions described in this
paragraph may result in the maintenance of the price of the Common Stock at a
level above that which might otherwise prevail in the open market. None of the
transactions described in this paragraph is required, and, if they are
undertaken, they may be discontinued at any time.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders of
Mercury Computer Systems, Inc.:
 
     We have audited the accompanying consolidated balance sheets of Mercury
Computer Systems, Inc. as of June 30, 1996 and 1997, and the related
consolidated statements of operations, changes in stockholders' equity, and cash
flows for each of the three years in the period ended June 30, 1997. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
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 consolidated financial position of Mercury
Computer Systems, Inc. as of June 30, 1996 and 1997, and the consolidated
results of its operations and its cash flows for each of the three years in the
period ended June 30, 1997, in conformity with generally accepted accounting
principles.

      INFORMATION AS OF SEPTEMBER 30, 1997, AND FOR THE THREE MONTHS ENDED
                   SEPTEMBER 30, 1996 AND 1997, IS UNAUDITED
 
A.  DESCRIPTION OF BUSINESS:
 
     Mercury Computer Systems, Inc. (the "Company") designs, manufactures and
markets high performance real-time digital signal processing computer systems
which transform sensor generated data into information which can be displayed as
images for human interpretation or subjected to additional computer analysis.
These multicomputer systems are heterogeneous and scalable, allowing them to
accommodate several different microprocessor types and to scale from a few to
hundreds of microprocessors within a single system. The two primary markets for
the Company's products are defense electronics and medical diagnostic imaging.
Both of these markets have computing needs which benefit from the unique system
architecture developed by the Company.
 
B.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  Basis of Presentation
 
     The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries. All material intercompany transactions and
balances have been eliminated.
 
  Interim Financial Information
 
     The consolidated financial statements of the Company as of September 30,
1997 and for the three months ended September 30, 1996 and 1997 are unaudited.
All adjustments (consisting only of normal recurring adjustments) have been made
which, in the opinion of management, are necessary for a fair presentation.
Results of operations for the three months ended September 30, 1997 are not
necessarily indicative of the results that may be expected for any future
period.
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the dates of the financial
statements and the reported amounts of revenues and expenses during the
reporting periods. Actual results could differ from those estimates.
 
  Revenue Recognition
 
     Revenue from product sales is generally recorded upon shipment to the
customer provided that no significant vendor obligations remain outstanding and
collection of the related receivable is deemed probable by management. If
insignificant vendor obligations remain after shipment of the product, the
Company accrues for the estimated costs of such obligations. Additionally, the
Company accrues for warranty costs upon shipment. Service revenue is recognized
ratably over applicable contract periods or as the services are performed.
Revenue from contracts involving significant product modification or
customization is recognized using the percentage-of-completion accounting method
on an efforts-expended basis. Changes to total estimated costs and anticipated
losses, if any, are recognized in the period in which determined. No revenue was
recognized under the percentage of completion method for the fiscal years ended
June 30, 1995 and 1996, and the three months ended September 30, 1996.
Approximately $2,102,000 and $901,000 of revenue was recognized under the
percentage-of-completion method for the fiscal year ended June 30, 1997, and the
three months ended September 30, 1997, respectively. There were no retainages at
June 30, 1996 and 1997 and September 30, 1997.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
           (TABLES IN THOUSANDS EXCEPT FOR SHARE AND PER SHARE DATA)
      INFORMATION AS OF SEPTEMBER 30, 1997, AND FOR THE THREE MONTHS ENDED
                   SEPTEMBER 30, 1996 AND 1997, IS UNAUDITED
 
  Contracts in Progress
 
     Contracts in progress include costs and estimated profits under uncompleted
contracts accounted for using the percentage-of-completion method, net of
amounts billed. Amounts billed at June 30, 1996 and 1997 and September 30, 1997,
which were netted against costs and estimated profits, were $0, $1,016,000 and
$1,091,000, respectively. Amounts billed at September 30, 1997 are expected to
be collected within the next twelve months.
 
  Billings in Excess of Revenues and Customer Advances
 
     Billings in excess of revenues and customer advances include amounts billed
on uncompleted contracts accounted for using the percentage-of-completion method
net of costs and estimated profits recognized.
 
  Cash and Cash Equivalents
 
     Cash equivalents, consisting of money market funds and U.S. government and
U.S. government agency issues with original maturities of 90 days or less, are
carried at cost which approximates fair value.
 
  Concentration of Credit Risk
 
     Financial instruments which potentially expose the Company to
concentrations of credit risk consist principally of cash and trade accounts
receivable. The Company places its cash and cash equivalents with financial
institutions which management believes are of high credit quality. At September
30, 1997, the Company had approximately $15,489,000 on deposit or invested with
its primary financial and lending institution.
 
     One customer accounted for approximately 19% and 57% of the accounts
receivable balances at June 30, 1996 and 1997, respectively. Two other customers
accounted for approximately 15% and 12% of the accounts receivable balance at
June 30, 1996, respectively. Three customers accounted for approximately 17%,
16% and 10%, respectively, of the accounts receivable balance at September 30,
1997. The Company performs ongoing credit evaluations of its customers and
maintains reserves for potential credit losses. Such losses have historically
been within management's expectations.
 
  Inventory
 
     Inventory is stated at the lower of cost, determined on the first-in,
first-out (FIFO) basis, or market.
 
  Property and Equipment
 
     Property and equipment are recorded at cost. Depreciation is based on the
following estimated useful lives of the assets using the straight-line method:

related cost and accumulated depreciation are removed from the accounts and any
resulting gain or loss is included in the results of operations.
 
  Capitalized Software Development Costs
 
     The Company capitalizes software development costs incurred after a
product's technological feasibility has been established and before it is
available for general release to customers. Amortization of capitalized software
costs is computed on an individual product basis and is the greater of a) the
ratio that current gross revenues for a product bear to the total of current and
anticipated future gross revenues for that product or b) the straight-line
method over the estimated economic life of the product. Currently, the Company
uses an estimated economic life of 36 months for all capitalized software costs.
 
  Income Taxes
 
     The Company recognizes deferred tax assets and liabilities for the expected
future tax consequences of events that have been included in the Company's
consolidated financial statements. Under this method, deferred tax liabilities
and assets are determined based on the difference between the financial
statement and tax bases of assets and liabilities using currently enacted tax
rates for the year in which the differences are expected to reverse. The Company
records a valuation allowance against net deferred tax assets if, based upon the
available evidence, it is more likely than not that some or all of the deferred
tax assets will not be realized.
 
  Net Income Per Common Share
 
     Net income per common share is based upon the weighted average number of
common and common equivalent shares (using the treasury stock method)
outstanding after certain adjustments described below. Common equivalent shares
are included in the per share calculations where the effect of their inclusion
would be dilutive. Common equivalent shares consist of outstanding stock
options, stock warrants, and the Series A convertible preferred stock. Pursuant
to Securities and Exchange Commission Staff Accounting Bulletin No. 83, all
common and common equivalent shares issued at prices less than the mid-point of
the estimated initial public offering price range during the twelve-month period
prior to the initial filing of the Registration Statement for the initial public
offering have been included in the calculation as if they were outstanding for
all periods using the treasury stock method and an assumed mid-point of the
estimated initial public offering price range of $13.00 per common share. Fully
diluted earnings per share is not presented, as the difference between primary
and fully diluted earnings per share is immaterial.
 
  Foreign Currency
 
     The accounts of foreign subsidiaries are translated using exchange rates in
effect at period-end for assets and liabilities and at average exchange rates
during the period for results of operations. The local currency for all foreign
subsidiaries is the functional currency. The related translation adjustments are
reported as a separate component of stockholders' equity. Gains (losses)
resulting from foreign currency transactions are included in other income
(expense) and are immaterial for all period presented.
 
  Reclassification
 
     Certain reclassifications have been made to the prior years' financial
statements to conform to the current year's presentation.

  New Accounting Pronouncements
 
     In February 1997, the Financial Accounting Standards Board (the "FASB")
issued Statement of Financial Accounting Standards ("SFAS") No. 128, "Earnings
Per Share," which is effective for both interim and annual periods ending after
December 31, 1997. Earlier adoption is not permitted. The statement requires
restatement of all prior period earnings per share data presented after the
effective date. SFAS No. 128 specifies the computation, presentation and
disclosure requirements for earnings per share and is substantially similar to
the standards recently issued by the International Accounting Standards
Committee entitled "International Accounting Standards, Earnings Per Share." The
Company will adopt SFAS No. 128 in the interim period ending December 31, 1997.
The impact of SFAS No. 128 will be immaterial to reported net income per common
share.
 
     In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income." This statement requires that changes in comprehensive income be shown
in a financial statement that is displayed with the same prominence as other
financial statements. The statement will be effective for annual periods
beginning after December 15, 1997 and the Company will adopt its provisions in
fiscal 1999. Reclassification for earlier periods is required for comparative
purposes. The Company is currently evaluating the impact this statement will
have on its financial statements; however, because the statement requires only
additional disclosure, the Company does not expect the statement to have a
material impact on its financial position or results of operations.
 
     In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of
an Enterprise and Related Information." This statement supersedes SFAS No. 14,
"Financial Reporting for Segments of a Business Enterprise." This statement
includes requirements to report selected segment information quarterly and
entity-wide disclosures about products and services, major customers, and the
material countries in which the entity holds assets and reports revenues. The
statement will be effective for annual periods beginning after December 15, 1997
and the Company will adopt its provisions in fiscal 1999. Reclassification for
earlier periods is required, unless impracticable, for comparative purposes. The
Company is currently evaluating the impact this statement will have on its
financial statements; however, because the statement requires only additional
disclosure, the Company does not expect the statement to have a material impact
on its financial position or results of operations.
 
     In October 1997, the American Institute of Certified Public Accountants
("AICPA") issued the statement of position ("SOP") 97-2 "Software Revenue
Recognition," which will supersede SOP 91-1. SOP 97-2 has not changed the basic
rules of revenue recognition but does provide more guidance particularly with
respect to multiple deliverables and "when and if available" products. SOP 97-2
is effective for transactions entered into for annual periods beginning after
December 15, 1997. The Company will adopt SOP 97-2 in fiscal 1999 and has not
yet determined its impact.

Offered Rate, payable monthly. The credit agreement contains certain covenants,
including restrictions on incurrence of additional indebtedness and liens on its
assets, capital expenditures, disposition of assets, investments and
acquisitions, limitations on distributions, and requires the Company to meet
certain financial tests pertaining to current and debt ratios and income before
tax provision. There were no borrowings outstanding at June 30, 1996 and 1997

     Rental expense during the fiscal years ended June 30, 1995, 1996 and 1997
and the three months ended September 30, 1996 and 1997 was approximately
$674,000, $670,000, $642,000, $140,000 and $203,000, respectively.
 
  Internal Revenue Service Audit
 
     On December 12, 1997, the Internal Revenue Service ("IRS") concluded an
audit of the Company's tax returns for the years ended June 30, 1992 through
June 30, 1995, and issued a formal report reflecting proposed adjustments with
respect to the years under audit. The proposed IRS adjustments primarily relate
to the disallowance of research and experimental tax credits claimed by the
Company, as well as the treatment of certain other items. The total deficiency
attributable to the proposed adjustments is $4,181,000, including penalties and
interest of $1,591,000 through the date of the report. The Company is in the
process of responding to this report by appealing the proposed adjustments to
the Appeals Division of the IRS. While the Company does not believe that the
final outcome of the IRS audit will have a material adverse effect on the
Company's financial condition or results of operations, no assurance can be
given as to the final outcome of the audit, the amount of any final adjustments
or the potential impact of such adjustments on the Company's financial condition
or results of operations.
 
G.  STOCKHOLDERS' EQUITY:
 
  Preferred Stock
 
     General
 
     The Company is authorized to issue 2,000,000 shares of preferred stock with
a par value of $.01 per share. Under the terms of the various agreements related
to the sale and/or issuance of the preferred stock, restrictions are placed on
the Company pertaining to dividends, mergers, incurrence of indebtedness and
reorganizations. These agreements also grant certain preferred stockholders'
representation on the Company's Board of Directors ("the Board"), demand
registration rights, piggyback registration rights and certain antidilutive
rights.
 
     Series A Convertible Preferred Stock
 
     The Series A Convertible Preferred Stock has a liquidation preference of
$1.41 per share and has voting rights similar to the common stock. Each of the
preferred stockholders has one vote for each share of Common Stock into which
the Series A Convertible Preferred Stock is convertible. The Series A
Convertible Preferred Stock is convertible, at the option of the holder, into
shares of the Company's Common Stock in accordance with a conversion formula
which would currently result in a three-for-one exchange with

mandatory conversion required in the event of a sale of the Company's Common
Stock in a public offering meeting a specified aggregate valuation.
 
     Series B Convertible Redeemable Preferred Stock
 
     On April 26, 1993, the Company redeemed all of the outstanding shares of
Series B Convertible Redeemable Preferred Stock for $3.00 per share resulting in
a $1,500,000 redemption and a $1,000,000 payment contingent on a qualified
public offering on or before April 26, 1995. During the fiscal year ended June
30, 1995, the contingent obligation expired and the remaining obligation was
reclassified to additional paid-in capital.
 
  Stock Options
 
     The Company has four stock option plans. The 1982, 1991 and 1993 Stock
Option Plans (the "Plans") provide for the granting of options to purchase an
aggregate of not more than 1,950,000 shares of the Company's Common Stock to
employees and directors. Under these plans, options are granted at not less than
the fair value of the stock on the date of grant as determined by the Board. The
terms of the options are established by the Board on an individual basis. The
options generally vest over five years and have a maximum term of ten years.
 
     The 1997 Stock Option Plan (the "1997 Plan"), which the Board approved in
June 1997, provides for the granting of options to purchase an aggregate of not
more than 575,000 shares of the Company's Common Stock. Under the 1997 Plan,
options are granted at not less than 50% of the fair value of the stock on the
date of grant as determined by the Board. The options vest over five years and
have a maximum term of ten years. With the implementation of the 1997 Plan, no
further stock options were granted under the 1982, 1991 and 1993 Stock Option
Plans. No options were granted under the 1997 Plan during the fiscal year ended
June 30, 1997. Options granted under the 1997 Plan during the three months ended
September 30, 1997 were granted at the fair value of the common stock on the
date of grant.
 
     In determining the fair value of the Stock at the date of grant under each
plan, the Board considered a broad range of factors including the illiquid
nature of an investment in the Company's Common Stock, transactions in the
Company's Common Stock with third parties, consultations with financial advisors
(as appropriate), the Company's historical financial performance relative to
that of comparable companies and its future prospects.

     In fiscal year 1997, the Company adopted SFAS No. 123, "Accounting for
Stock-Based Compensation." SFAS No. 123 requires that companies either recognize
compensation expense for grants of stock, stock options and other equity
instruments based on fair value or provide pro forma disclosure of net income
and earnings per share in the notes to the financial statements. The Company
adopted the disclosure provisions of SFAS No. 123 in fiscal 1997 and has applied
APB Opinion No. 25 and related Interpretations in accounting for all of its
stock option plans. Accordingly, no compensation cost has been recognized for
its stock option plans as compensation cost is measured as the excess, if any,
of the fair market value of the Company's stock at the date of grant over the
amount an individual must pay to acquire the stock.

fair value of each option granted during the fiscal years ended June 30, 1996
and 1997 is estimated on the date of grant using the Black-Scholes option
pricing model with the following assumptions: an expected life of eight years, a
dividend yield of 0%, a risk free interest rate of 6.8% and zero expected
volatility.
 
     Had compensation cost for the Company's stock option grants been determined
based on the fair value at the grant dates, as calculated in accordance with
SFAS No. 123, the Company's net income and net income per common share for the
fiscal years ended June 30, 1996 and 1997 and the three months ended September
30, 1997, would approximate the following pro forma amounts as compared to the

     Repricing Stock Options
 
     On July 30, 1996, the Board approved a plan (the "repricing plan") to
reprice employee stock options under the Plans to restore the long-term employee
retention and performance incentives of the stock options outstanding. In
accordance with the repricing plan, all stock options with exercise prices above
$4.00 per share and approved by the individual optionholder were canceled and
replaced by the same number of options exercisable at $4.00 per share, the fair
value of the Company's common stock as determined by the Board on the date of
the repricing. In reaching this determination, the Board considered a broad
range of factors including the illiquid nature of an investment in the Company's
Common Stock, transactions of the Company's Common Stock with third parties, the
Company's historical financial performance relative to that of comparable
companies and its future prospects. Fifty percent of those options which were
vested prior to the repricing vested immediately under the repricing plan. All
remaining previously vested and unvested options will vest in accordance with
the current option plan.
 
     Warrants
 
     At June 30, 1996 and 1997, a warrant to purchase 10,000 shares of the
Company's Common Stock was outstanding with an exercise price of $2.00 per share
and exercisable through June 30, 2000. In September 1997, the warrants were
exercised.

     No valuation allowance was deemed necessary for the deferred tax asset.
Although realization is not assured, management believes it is more likely than
not that all of the deferred tax asset will be realized. The amount of the
deferred tax asset considered realizable, however, could be reduced in the near
term if estimates of future taxable income during the carryforward period are
reduced.

ITEM 14.  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>   85
 
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 Bylaws, 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
corporation.
 
     The Underwriting Agreement provides that the Underwriters are obligated,
under certain circumstances, to indemnify directors, officers and controlling
persons of the Company against certain liabilities, including liabilities under
the Securities Act. Reference is made to the form of Underwriting Agreement
filed as Exhibit 1.1 hereto.
 
     The Company maintains directors and officers liability insurance for the
benefit of its directors and certain of its officers and has entered into
indemnification agreements with its directors and certain of its officers.

ITEM 17.  UNDERTAKINGS
 
     The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the registration statement 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 offering thereof.
 
     The undersigned registrant hereby undertakes that: (1) For purposes of
determining any liability under the Securities Act, the information omitted from
the form of prospectus filed as part of his 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; and (2) For the purpose of determining any liability under the
Securities Act, 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 offering thereof.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to provisions described in Item 14 above, or otherwise, the
registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities 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 registrant
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 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.

Rule 424(b) under the Act, and in the case of either clause (i)(A) or (i)(B) of

Company may also file a related registration statement with the Commission

and the term "Term Sheet" means any term sheet that satisfies the requirements
of Rule 434 under the Act. Any reference herein to the "date" of a Prospectus
that includes a Term Sheet shall mean the date of such Term Sheet.

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) 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, (i) 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

provisions of this paragraph (b) do not apply to statements or omissions made in
any Preliminary Prospectus, 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.

     (c) If the Company has elected to rely on Rule 462(b) and the Rule 462(b)

a Rule 462(b) Registration Statement in compliance with, and that is effective
upon filing pursuant to, Rule 462(b) and has received confirmation of its
receipt and (ii) the Company has given irrevocable instructions for transmission

Registration Statement, in compliance with Rule 111 promulgated under the Act or
the Commission has received payment of such filing fee.

     (d) The Company has no subsidiaries other than those listed in SCHEDULE IV
hereto. 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 would not have a
material adverse effect on the Company and its subsidiaries, taken as a whole.

     (e) The Company and each of its subsidiaries have full power (corporate or
limited liability company) 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 corporate or limited liability
company power to enter into this Agreement and to carry out all the terms and
provisions hereof to be carried out by it.

     (f) 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, except as otherwise set forth in the Prospectus or, if the
Prospectus is not in existence, the most recent Preliminary Prospectus, are
owned beneficially by the Company free and clear of any security interests,
liens, encumbrances, equities or claims.

     (g) The Company's authorized, issued and outstanding capitalization is set
forth in the Prospectus or, if the Prospectus is not in existence, the most
recent Preliminary Prospectus. All of the issued and outstanding 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 


                                       4

<PAGE>   5

the Company to register the offer or sale of any securities owned by such holder
under the Act in the public offering contemplated by this Agreement.

     (h) After giving effect to the amendment to the Company's Articles of
Organization described in the Prospectus, 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.

     (i) Except as disclosed in the Prospectus (or, if the Prospectus is not in
existence, the most recent Preliminary Prospectus), 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.

     (j) 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 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) fairly present, on the basis stated in the Prospectus
(or such Preliminary Prospectus), the information included therein.

     (k) Coopers & Lybrand L.L.P., who have certified certain financial
statements of the Company and its consolidated subsidiaries and delivered their
report with respect to the audited consolidated financial statements and
schedules included in the Registration Statement and the Prospectus (or, if the
Prospectus is not in existence, the most recent Preliminary Prospectus), are
independent public accountants as required by the Act and the applicable rules
and regulations thereunder.

     (l) The execution and delivery of this Agreement have been duly authorized
by the Company, and this Agreement has been duly executed and delivered by the
Company, and is the valid and binding agreement of the Company, enforceable
against the Company in accordance with its terms.

     (m) No legal or governmental proceedings are pending to which 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 described therein (or, if
the Prospectus is not in existence, the most recent Preliminary


                                       5

Prospectus), and no such proceedings have been threatened against the Company or
any of its subsidiaries or with respect to any of their respective properties;
and no contract or other document is required to be described in the
Registration Statement or the Prospectus or to be filed as an exhibit to the
Registration Statement that is not described therein (or, if the Prospectus is
not in existence, the most recent Preliminary Prospectus) or filed as required.

     (n) 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 (i) 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 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 (ii) 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.

of its subsidiaries has sustained any material loss or interference with their
respective businesses or properties from fire, flood, hurricane, accident or
other calamity, whether or not covered by insurance, or from any labor dispute
or any legal or governmental proceeding and there has not been any material
adverse change, or any development involving a prospective material adverse
change, in the condition (financial or otherwise), management, business
prospects, net worth, or results of the operations of the Company or any of its
subsidiaries, except in each case as described in or contemplated by the
Prospectus or, if the Prospectus is not in existence, the most recent
Preliminary Prospectus.

     (p) The Company has not, directly or indirectly, (i) 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 of the
price of any security of the Company to facilitate the sale or resale of the
Securities or (ii) since the filing of the Registration Statement (A) sold, bid
for, purchased, or paid anyone any compensation for soliciting purchases of, the

Closing Date and (ii) the completion of the distribution of the Securities, will

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

     (s) 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

interfere with the use 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

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

     (a) Such Selling Stockholder has full power to enter into this Agreement
and to sell, assign, transfer and deliver to the Underwriters the Securities to
be sold by such Selling Stockholder hereunder in accordance with the terms of
this Agreement; and this Agreement has been duly executed and delivered by such

Stockholder, enforceable against each such Selling Stockholder in accordance
with its terms.


                                       9


<PAGE>   10



     (b) Such Selling Stockholder has duly executed and delivered a power of
attorney and custody agreement (with respect to such Selling Stockholder, the
"Power-of-Attorney" and the "Custody Agreement", respectively), each in the form
heretofore delivered to the Representatives, appointing James R. Bertelli and R.
Schorr Berman as such Selling Stockholder's attorney-in-fact (the
"Attorney-in-Fact") with authority to execute, deliver and perform this
Agreement on behalf of such Selling Stockholder and appointing Hutchins, Wheeler
& Dittmar, A Professional Corporation, as custodian thereunder (the
"Custodian"). Certificates in negotiable form, endorsed in blank or accompanied
by blank stock powers duly executed, with signatures appropriately guaranteed,
representing the Securities to be sold by such Selling Stockholder hereunder
have been deposited with the Custodian pursuant to the Custody Agreement for the
purpose of delivery pursuant to this Agreement. Such Selling Stockholder has
full power to enter into the Custody Agreement and the Power-of-Attorney and to
perform its obligations under the Custody Agreement. If such Selling Stockholder
is a corporation, the execution and delivery of the Custody Agreement and the
Power-of-Attorney have been duly authorized by all necessary corporate action of
such Selling Stockholder; the Custody Agreement and the Power-of-Attorney have
been duly executed and delivered by such Selling Stockholder and, assuming due
authorization, execution and delivery by the Custodian, are the legal, valid,
binding and enforceable instruments of such Selling Stockholder. Such Selling
Stockholder agrees that each of the Securities represented by the certificates
on deposit with the Custodian is subject to the interests of the Underwriters
hereunder, that the arrangements made for such custody, the appointment of the
Attorney-in-Fact and the right, power and authority of the Attorney-in-Fact to
execute and deliver this Agreement, to agree on the price at which the
Securities (including such Selling Stockholder's Securities) are to be sold to
the Underwriters, and to carry out the terms of this Agreement, are to that
extent irrevocable and that the obligations of such Selling Stockholder
hereunder shall not be terminated, except as provided in this Agreement or the
Custody Agreement, by any act of such Selling Stockholder, by operation of law
or otherwise, whether in the case of any individual Selling Stockholder by the
death or incapacity of such Selling Stockholder, in the case of a trust or
estate by the death of the trustee or trustees or the executor or executors or
the termination of such trust or estate, or in the case of a corporate or
partnership Selling Stockholder by its liquidation or dissolution or by the
occurrence of any other event. If any individual Selling Stockholder, trustee or
executor should die or become incapacitated or any such trust should be
terminated, or if any corporate or partnership Selling Stockholder shall
liquidate or dissolve, or if any other event should occur, before the delivery
of such Securities hereunder, the certificates for such Securities deposited
with the Custodian shall be delivered by the Custodian in accordance with the
respective terms and conditions of this Agreement as if such death, incapacity,
termination, liquidation or dissolution or other event had not occurred,
regardless of whether or not the Custodian or the Attorney-in-Fact shall have
received notice thereof.

     (c) Such Selling Stockholder is the lawful owner of the Securities to be
sold by such Selling Stockholder hereunder and upon sale and delivery of, and
payment for, such Securities, as provided herein, such Selling Stockholder will
convey good and marketable title to such Securities, free and clear of any
security interests, liens, encumbrances, equities, claims or other defects. Such
Selling Stockholder has obtained all authorizations and approvals required by
law and under its charter or bylaws, partnership agreement, trust agreement or
other organizational 


                                       10

documents, as the case may be, to enter this Agreement, such Selling
Stockholder's Power of Attorney and Custody Agreement, to sell, transfer and
deliver all of the shares of Common Stock which may be sold by such Selling
stockholder pursuant to this Agreement; and to comply with other obligations
hereunder and thereunder.

     (d) Such Selling Stockholder has not, directly or indirectly, (i) taken any
action designed to cause or result in, or that has constituted or which might
reasonably be expected to constitute, the stabilization or manipulation of the
price of any security of the Company to facilitate the sale or resale of the
Securities or (ii) since the filing of the Registration Statement (A) sold, bid
for, purchased, or paid anyone any compensation for soliciting purchases of, the
Securities or (B) 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 Stockholders under this Agreement).

     (e) To the extent that any statements or omissions are made in the
Registration Statement, any Preliminary Prospectus, the Prospectus or any
amendment or supplement thereto in reliance upon and in conformity with written
information furnished to the Company by such Selling Stockholder specifically
for use therein, such Preliminary Prospectus did, and the Registration Statement
and the Prospectus and any amendments or supplements thereto, when they become
effective or are filed with the Commission, as the case may be, will conform in
all material respects to the requirements of the Act and the respective rules
and regulations of the Commission thereunder and will not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein, in the light of the
circumstances under which they are made, not misleading. Such Selling
Stockholder has reviewed the Prospectus (or, if the Prospectus is not in
existence, the most recent Preliminary Prospectus) and the Registration
Statement, and the information regarding such Selling Stockholder set forth
therein under the caption "Principal and Selling Stockholders" is complete and
accurate.

     (f) The sale by such Selling Stockholder of Securities pursuant hereto is
not prompted by any adverse information known to such Selling Stockholder
concerning the Company that is not set forth in the Registration Statement or
the Prospectus (or, if the Prospectus is not in existence, the most recent
Preliminary Prospectus).

     (g) The sale of the Securities to the Underwriters by such Selling
Stockholder pursuant to this Agreement, the compliance by such Selling
Stockholder with the other provisions of this Agreement, the Power of Attorney,
the Custody Agreement and the consummation of the other transactions herein
contemplated do not (i) 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 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 (ii) 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 such
Selling Stockholder or, if applicable, to which 


                                       11


<PAGE>   12

such Selling Stockholder or any of its subsidiaries is a party or by which such
Selling Stockholder or, if applicable, by which such Selling Stockholder or any
of its subsidiaries or any of such Selling Stockholder's properties are bound,
or the charter documents or by-laws of such Selling Stockholder or any statute
or any judgment, decree, order, rule or regulation of any court or other
governmental authority or any arbitrator applicable to such Selling Stockholder
or, if applicable, to such Selling Stockholder or any of its subsidiaries.

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

     2(C). ADDITIONAL REPRESENTATIONS AND WARRANTIES OF THE PRINCIPAL SELLING
STOCKHOLDERS. Each Principal Selling Stockholder represents and warrants to, and
agrees with, each of the several Underwriters, severally and not jointly, that
nothing has come to the attention of such Principal Selling Stockholder that
would cause such Principal Selling Stockholder to believe that:

     (a) any of the Company's representations and warranties set forth in
Section 2(A) hereof was untrue as of the date any such representation or
warranty was made; or

     (b) (1) when any Preliminary Prospectus was filed with the Commission it
(i) did not contain all statements required to be stated therein in accordance
with, or did not comply in all material respects with the requirements of, the
Act and the rules and regulations of the Commission thereunder or (ii) included
any untrue statement of a material fact or omitted 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;

         (2) when the Registration Statement or any amendment thereto was or is
declared effective, it (i) did not contain or will not contain all statements
required to be stated therein in accordance with, or did not comply or will not
comply in all material respects with the requirements of, the Act and the rules
and regulations of the Commission thereunder or (ii) included or will include
any untrue statement of a material fact or omitted or will omit to state any
material fact necessary to make the statements therein not misleading;

         (3) when the Prospectus or any Term Sheet that is a part thereof or
any amendment or supplement to the Prospectus is filed with the Commission
pursuant to Rule 424(b) (or, if the Prospectus or part thereof 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) and on the Firm Closing Date and any Option
Closing Date, the Prospectus, as amended or supplemented at any such time, (i)
did not or will not contain all statements required to be stated therein in
accordance with, or did not or will not comply in all material respects with the
requirements of, the Act and the rules and regulations of the Commission
thereunder or (ii) included or will include any untrue statement of a material
fact or omitted or will omit to state any material fact necessary in order to
make the statements therein, in the light of the circumstances under which they

                                       12

<PAGE>   13

unless, in the case of (b) above, any such statements or omissions made in any
Preliminary Prospectus, the Registration Statement or any amendment thereto or
the Prospectus or any amendment or supplement thereto were made in reliance upon
and in conformity with written information furnished to the Company or any
Principal Selling Stockholder by any Underwriter through the Representatives
specifically for use therein.

     3. PURCHASE, SALE AND DELIVERY OF THE SECURITIES. (a) On the basis of the
representations, warranties, agreements and covenants herein contained and
subject to the terms and conditions herein set forth, (A) the Company agrees to
issue and sell to each of the Underwriters, severally and not jointly, and each
of the Underwriters, severally and not jointly, agrees to purchase from the
Company, at a purchase price of $________ per share, the number of Firm
Securities set forth opposite the name of such Underwriter in Column (a) of
SCHEDULE III hereto and (B) each of the Selling Stockholders, severally and not
jointly, agrees to sell to the Underwriters, severally and not jointly, the
number of Firm Securities set forth opposite the name of such Selling
Stockholder in Column (a) of SCHEDULE I or SCHEDULE II hereto, as the case may
be, and each of the Underwriters, severally and not jointly, agrees to purchase
from the Selling Stockholders, severally and not jointly, the number of Firm
Securities set forth opposite the name of such Underwriter in Column (b) of
SCHEDULE III hereto. One or more certificates in definitive form for the Firm
Securities that the several Underwriters have agreed to purchase hereunder, and
in such denomination or denominations and registered in such name or names as
the Representatives request upon notice to the Company at least 48 hours prior
to the Firm Closing Date, shall be delivered by or on behalf of the Company and
the Selling Stockholders to the Representatives for the respective accounts of
the Underwriters, against payment by or on behalf of the Underwriters of the
purchase price therefor by wire transfer in same-day funds (the "Wired Funds")
to the respective accounts of the Company and the Selling Stockholders. Such
delivery of and payment for the Firm Securities shall be made at the offices of
Testa, Hurwitz & Thibeault, LLP, High Street Tower, 125 High Street, Boston,
Massachusetts 02110 at 9:30 A.M., New York time, on February ___, 1998, or at
such other place, time or date as the Representatives, the Company and the
Selling Stockholders 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
Stockholders 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 and each Selling Stockholder, severally and not jointly, hereby
grant to the several Underwriters options to purchase, severally and not
jointly, the number of Option Securities set forth opposite the name of such
Underwriter in Column (c) of SCHEDULE III hereto with respect to the Selling
Stockholders and in Column (d) of SCHEDULE III hereto with respect to the
Company. The options granted hereby (i) shall be exercised FIRST as to the
shares subject to such options which are offered by the Selling Stockholders as
set forth opposite the name of such Selling Stockholder in Column (b) of
SCHEDULE I or SCHEDULE II hereto, as the case may be, PRO RATA among the Selling


                                       13

<PAGE>   14

Stockholders based upon the percentage obtained for each Selling Stockholder by
computing a fraction the numerator of which is the number of shares so offered
by a Selling Stockholder as set forth opposite the name of such Selling
Stockholder in Column (b) of SCHEDULE I or SCHEDULE II hereto, as the case may
be, and the denominator of which is the total number of shares so offered by all
Selling Stockholders (calculated by figuring the sum of the "total" rows of
Column (b) in each of SCHEDULE I and SCHEDULE II hereto) and SECOND as to the
shares subject to such options which are offered by the Company and (ii) subject
to the preceding clause (i), may be exercised as to all or any part of the
Option Securities from time to time 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 options. The Representatives
may from time to time exercise the options granted hereby by giving notice in
writing or by telephone (confirmed in writing) to the Selling Stockholder from
whom such option is being exercised (and the Attorneys-in-Fact) and/or the
Company, as the case may be, setting forth the aggregate number of Option
Securities as to which the several Underwriters are then exercising such 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 five business days after
such exercise of such 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 Selling Stockholders (and
the Attorneys-in-Fact) and/or the Company, as the case may be, 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 such option as provided herein, such Selling Stockholder and/or the
Company, as the case may be, 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 such Selling Stockholder and/or the Company, as the case may be,
the number of Option Securities set forth opposite the name of Underwriter in
Column (c) of SCHEDULE III hereto with respect to the Selling Stockholders and
Column (d) of SCHEDULE III hereto with respect to the Company, in the same
percentage of the total number of the Option Securities as to which the several
Underwriters are then exercising such 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 such 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) The Company and each Selling Stockholder hereby acknowledge that the
wire transfer by or on behalf of the Underwriters of the purchase price for any
Securities does not constitute closing of a purchase and sale of the Securities.
Only execution and delivery of a receipt for Securities by the Underwriters
indicates completion of the closing of a purchase of the Securities from the
Company or any Selling Stockholder. Furthermore, in the event that the


                                       14


<PAGE>   15

Underwriters wire funds to the Company or any Selling Stockholder prior to the
completion of the closing of a purchase of Securities, the Company and each
Selling Stockholder hereby acknowledge that until the Underwriters execute and
deliver a receipt for the Securities, by facsimile or otherwise, the Company and
each Selling Stockholder will not be entitled to the wired funds and shall
return the wired funds to the Underwriters as soon as practicable (by wire
transfer of same-day funds) upon demand. In the event that the closing of a
purchase of Securities is not completed and the wire funds are not returned by
the Company or any Selling Stockholder to the Underwriters on the same day the
wired funds were received by the Company or any Selling Stockholder, the Company
and each Selling Stockholder agrees to pay to the Underwriters in respect of
each day the wire funds are not returned by it, in same-day funds, interest on
the amount of such wire funds in an amount representing the Underwriters' cost
of financing as reasonably determined by Prudential Securities Incorporated.

     (d) 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 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.

     5. COVENANTS OF THE COMPANY AND THE SELLING STOCKHOLDERS.

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

     (a) 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 or any Term Sheet that constitutes a part
thereof and any amendment or supplement thereto with the Commission in the
manner and within the time period required by Rules 434 and 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 (i) will comply with all requirements
imposed upon it by the Act and the 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 (ii) will not file with the
Commission the prospectus, Term Sheet or the amendment referred to in the second
sentence of Section 2(A)(a) hereof, any amendment or supplement to such
Prospectus, Term Sheet or any amendment to the Registration Statement or any
Rule 462(b) Registration Statement of which the Representatives 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 

                                       15

<PAGE>   16


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.

     (b) The Company will advise the Representatives, promptly after receiving
notice or obtaining knowledge thereof, of (i) the issuance by the Commission of
any stop order suspending the effectiveness of the Original Registration
Statement or any Rule 462(b) Registration Statement or any amendment thereto or
any order preventing or suspending the use of any Preliminary Prospectus or the
Prospectus or any amendment or supplement thereto, (ii) the suspension of the
qualification of the Securities for offering or sale in any jurisdiction, (iii)
the institution, threatening or contemplation of any proceeding for any such
purpose or (iv) any request made by the Commission for amending the Original
Registration Statement or any Rule 462(b) Registration Statement, for amending
or supplementing 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.

     (c) 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.

     (d) If, at any time prior to the later of (i) the final date when a
prospectus relating to the Securities is required to be delivered under the Act
or (ii) 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 or the rules or
regulations of the Commission thereunder, the Company will promptly notify the
Representatives thereof and, subject to Section 5(a) 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.

     (e) The Company will, without charge, provide (i) to the Representatives
and to counsel for the Underwriters a conformed copy of the registration
statement originally filed with respect to the Securities and each amendment
thereto (in each case including exhibits thereto) or any Rule 462(b)
Registration Statement, certified by the Secretary or an Assistant Secretary of
the Company to be true and complete copies thereof as filed with the Commission
by electronic transmission, (ii) to each other Underwriter, a conformed copy of
such registration statement or 


                                       16


<PAGE>   17

any Rule 462(b) Registration Statement and each amendment thereto (in each case
without exhibits thereto) and (iii) 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 request; without limiting the application
of clause (iii) of this sentence, the Company, not later than (A) 6:00 PM, New
York City time, on the date of determination of the public offering price, if
such determination occurred at or prior to 10:00 A.M., New York City time, on
such date or (B) 2:00 PM, New York City time, on the business day following the
date of determination of the public offering price, if such determination
occurred after 10:00 A.M., New York City time, on such date, will deliver to the
Underwriters, without charge, as many copies of the Prospectus and any amendment
or supplement thereto as the Representatives may reasonably request for purposes
of confirming orders that are expected to settle on the Firm Closing Date.

     (f) The Company, as soon as practicable, will make generally 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.

     (g) The Company will apply the net proceeds from the sale of the Securities
as set forth under "Use of Proceeds" in the Prospectus.

     (h) The Company will not, directly or indirectly, without the prior written
consent of Prudential Securities Incorporated, on behalf of the Underwriters,
offer, sell, offer to sell, contract to sell, pledge, grant any option to
purchase or otherwise sell or dispose (or announce any offer, sale, offer of
sale, contract of sale, pledge, grant of any option to purchase or other sale or
disposition) of any shares of Common Stock or any securities convertible into,
or exchangeable or exercisable for, shares of Common Stock for a period of 180
days after the date hereof, and except for issuances pursuant to the exercise of
employee stock options pursuant to the Company's stock option plans and its
employee stock purchase plan in effect as of the date hereof. Prudential
Securities Incorporated may, in its sole discretion, at any time and without
prior notice, release all or any portion of the shares of Common Stock subject
to such agreement.

     (i) The Company will not, directly or indirectly, (i) take 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 of the
price of any security of the Company to facilitate the sale or resale of the
Securities or (ii) (A) sell, bid for, purchase, or pay anyone any compensation
for soliciting purchases of, the Securities or (B) pay or agree 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 Stockholders
under this Agreement).

     (j) The Company will use all commercially reasonable efforts to obtain the
agreements described in Section 7(g) hereof prior to the Firm Closing Date.

     (k) If at any time during the 25-day period after the Registration
Statement becomes effective or the period prior to the Option 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 

                                       17

<PAGE>   18

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 notice from you advising
the Company to the effect set forth above and with our consent (which consent
shall not be unreasonably withheld or delayed), 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.

     (l) If the Company elects to rely on Rule 462(b), the Company shall both
file a Rule 462(b) Registration Statement with the Commission in compliance with
Rule 462(b) and pay the applicable fees in accordance with Rule 111 promulgated
under the Act by the earlier of (i) 10:00 P.M. Eastern time on the date of this
Agreement and (ii) the time confirmations are sent or given, as specified by
Rule 462(b)(2).

     (m) The Company will cause the Securities to be duly included for quotation
on The Nasdaq Stock Market's National Market (the "Nasdaq National Market")
prior to the Firm Closing Date. The Company will use its best efforts to ensure
that the Securities remain included for quotation on the Nasdaq National Market
or are included for quotation on another national quotation system or listed on
a national securities exchange following the Firm Closing Date.

     (n) 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.

       (B) Each of the Selling Stockholders covenants and agrees with each of 
the Underwriters that:

     (a) such Selling Stockholder will not, directly or indirectly, without the
prior written consent of Prudential Securities Incorporated, offer, sell, offer
to sell, contract to sell, pledge, grant any option to purchase or otherwise
sell or dispose (or announce any offer, sale, offer of sale, contract of sale,
pledge, grant of any option to purchase or other sale or disposition) of any
Securities legally or beneficially owned by such Selling Stockholder or any
securities convertible into, or exchangeable or exercisable for, Securities for
a period of 180 days after the date hereof. Prudential Securities Incorporated
may, in its sole discretion, at any time and without prior notice, release all
or any portion of the shares of Common Stock subject to such agreements;
PROVIDED, HOWEVER, that notwithstanding the foregoing restrictions on transfer
(collectively, the "Restrictions"), such Selling Stockholder shall be permitted
to make the following transfers: (i) transfers of shares of Common Stock made by
gift, provided the donee thereof agrees in writing to be bound by the
Restrictions; (ii) transfers of shares of Common Stock to members of such
Selling Stockholder's immediate family or to a trust or similar estate planning
entity established for the benefit of such Selling Stockholder or a member of
such Selling Stockholder's immediate family, provided that each transferee
agrees in writing to be bound by the Restrictions; (iii) transfers of shares of
Common Stock to the transferor's affiliates, as such term is defined in Rule 405
under the Act, provided that each transferee agrees in writing to be bound by
the 

                                       18

<PAGE>   19

Restrictions; (iv) transfers of shares of Common Stock made with the prior
written consent of Prudential Securities Incorporated on behalf of the
Underwriters; and (v) transfers of shares of Common Stock pursuant to the
Registration Statement.

     (b) such Selling Stockholder will not, directly or indirectly, (i) take any
action designed to cause or result in, or that has constituted or which might
reasonably be expected to constitute, the stabilization or manipulation of the
price of any security of the Company to facilitate the sale or resale of the
Securities or (ii) (A) sell, bid for, purchase, or pay anyone any compensation
for soliciting purchases of, the Securities or (B) pay or agree 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 Stockholders
under this Agreement).

     (c) in order to document the Underwriters' compliance with the reporting
and withholding provisions of the Internal Revenue Code of 1986, as amended,
with respect to the transactions herein contemplated, such Selling Stockholder
agrees to deliver to you prior to or on the Firm Closing Date, as hereinafter
defined, a properly completed and executed United States Treasury Department
Form W-8 or W-9 (or other applicable form of statement specified by Treasury
Department regulations in lieu thereof).

     6. EXPENSES. The Company will pay all costs and expenses incident to the
performance of the obligations of the Company and the Selling Stockholders under
this Agreement, whether or not the transactions contemplated herein are

     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

     conflict with or result in a breach or violation of any of the terms and

     of which may be listed in an exhibit to such counsel's opinion, to which
     the Company or any of the U.S. Subsidiaries is a party or by which the
     Company or any of the U.S. Subsidiaries or any of their respective

     order, rule or regulation of any court or other governmental authority or
     any arbitrator known to such counsel and applicable to the Company or U.S.
     Subsidiaries;

          (ix) such counsel has been informed by the Commission that the
     Registration Statement is effective under the Act; any required filing of
     the Prospectus, or any Term Sheet that constitutes a part thereof, pursuant

     period required by Rules 434 and 424(b); such counsel has been informed by

          (x) the Registration Statement originally filed with respect to the
     Securities and each amendment thereto, any Rule 462(b) Registration
     Statement and the Prospectus (in each case, other than the financial
     statements and other financial information contained therein, as to which
     such counsel need express no opinion) comply as to form in all material
     respects with the applicable requirements of the Act and the rules and

                                       22


<PAGE>   23


          (xi) if the Company elects to rely on Rule 434, the Prospectus is not
     "materially different", as such term is used in Rule 434, from the
     prospectus included in the Registration Statement at the time of its
     effectiveness or an effective post-effective amendment thereto (including
     such information that is permitted to be omitted pursuant to Rule 430A).

     Such counsel shall also state that they have no reason to believe that the
Registration Statement, as of its effective date, contained any untrue statement
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.

     (b)(2) The Representatives shall have received an opinion, dated the Firm
Closing Date, of Hutchins, Wheeler & Dittmar, counsel for the Selling
Stockholders, to the effect that:

          (i) each Selling Stockholder has full corporate, partnership or trust
     power, as applicable, to enter into this Agreement, the Custody Agreement
     and the Power-of-Attorney and to sell, transfer and deliver the Securities
     being sold by such Selling Stockholder hereunder in the manner provided in
     this Agreement and to perform its obligations under the Custody Agreement;
     if such Selling Stockholder is a corporation, the execution and delivery of
     this Agreement, the Custody Agreement and the Power-of-Attorney have been
     duly authorized by all necessary corporate action of each Selling
     Stockholder; this Agreement, the Custody Agreement and the
     Power-of-Attorney have been duly executed and delivered by each Selling
     Stockholder; the Custody Agreement and the Power-of-Attorney are the legal,
     valid, binding and enforceable instruments of each Selling Stockholder,
     subject to applicable bankruptcy, insolvency and similar laws affecting
     creditors' rights generally and subject, as to enforceability, to general
     principles of equity (regardless of whether enforcement is sought in a
     proceeding in equity or at law);

          (ii) when the Underwriters obtain control of the Securities to be sold
     by the Selling Stockholders, assuming that the Underwriters purchased such
     Securities for value and without notice of any adverse claim to such
     Securities within the meaning of Section 8-102 of the Uniform Commercial
     Code as in effect in the Commonwealth of Massachusetts, the Underwriters
     will have acquired all rights of the Selling Stockholders in such
     Securities free of any adverse claim;

          (iii) the sale of the Securities to the Underwriters by each Selling
     Stockholder pursuant to this Agreement, the compliance by such Selling
     Stockholder with the other provisions of this Agreement, the Custody
     Agreement and the consummation of the other transactions herein
     contemplated do not (i) require the consent, approval, authorization,
     registration or qualification of or with any governmental authority, except
     such as have been obtained and such as may be required under state
     securities or blue sky laws, or (ii) 


                                       23

<PAGE>   24

     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 such Selling
     Stockholder is a party or by which such Selling Stockholder or any of such
     Selling Stockholder's properties are bound, or the charter documents or
     by-laws of such Selling Stockholder 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 such Selling
     Stockholder.

     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, the Selling Stockholders and
representations and warranties of the Company and the Selling Stockholders
contained herein, in the Custody Agreements and in the Powers of Attorney.

     (b)(3) The Representatives shall have received opinions of counsel, dated
the Firm Closing Date, from local counsel to each of the Company's subsidiaries
organized outside of the United States in form and substance satisfactory to the
Representatives and counsel to the Representatives.

     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 Representatives shall have received an opinion, dated the Firm
Closing Date, of Testa, Hurwitz & Thibeault, LLP, 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.

     (d) The Representatives shall have received from Coopers & Lybrand L.L.P. a
letter or letters dated, respectively, the date hereof and the Firm Closing
Date, 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 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 and the related published
     rules and regulations;

          (iii) on the basis of a reading of the latest available interim
     unaudited consolidated financial statements of the Company, a reading of
     the unaudited amounts for revenues, cost of revenues, net income before
     income taxes and total and per share amounts of 


                                       24

<PAGE>   25

     net income as of and for the three months ended September 30, 1997 and of
     the unaudited consolidated financial statements of the Company and its
     consolidated subsidiaries for the periods 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
     inquiries of certain officials of the Company and its consolidated
     subsidiaries who have 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
          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 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;

          (B) the unaudited amounts for revenues, cost of revenues, net income
          before income taxes and total and per share amounts of net income
          included in the Registration Statement and the Prospectus do not agree
          with the amounts set forth in any unaudited consolidated financial
          statements for those same periods or are not in conformity with
          generally accepted accounting principles applied on a basis
          substantially consistent with that of the corresponding amounts in the
          audited consolidated financial statements included in the Registration
          Statement and the Prospectus; and

          (C) at a specific date not more than five business days prior to the
          date of such letter, 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' equity of the Company
          and its consolidated subsidiaries, in each case compared with amounts
          shown on the September 30, 1997 unaudited consolidated balance sheet
          included in the Registration Statement and the Prospectus, or for the
          period from November 1, 1997 to such specified date there were any
          decreases, as compared with the corresponding period in the preceding
          year, in revenues, cost of revenues, net income before 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 Financial Data,
Management's Discussion and Analysis of Financial Condition and Results of
Operations, Business and Description of Capital Stock, and in Exhibit 11 to the
Registration Statement, 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 


                                       25

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 (d) with respect to either letter referred to above shall include any
amendment or supplement thereto at the date of such letter.

     (e) The Representatives shall have received a certificate, dated the Firm
Closing Date, of the principal executive officer and the principal financial or
accounting officer of the Company to the effect that:

          (i) the representations and warranties of the Company in this
     Agreement are true and correct as if made on and as of the Firm Closing
     Date; the Registration Statement, as amended as of the Firm Closing Date,

     any material fact necessary to make the statements therein not misleading,
     and the Prospectus, as amended or supplemented as of the Firm Closing Date,
     does 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; and
     the Company has performed all covenants and agreements and satisfied all
     conditions on its part to be performed or satisfied at or prior to the Firm
     Closing Date;

          (ii) no stop order suspending the effectiveness of the Registration
     Statement or any amendment thereto has been issued, and no proceedings for
     that purpose have been instituted or threatened or, to the best of the
     Company's knowledge, are contemplated by the Commission; and

          (iii) subsequent to the respective dates as of which information is
     given in the Registration Statement and the Prospectus, neither the Company
     nor any of its subsidiaries has sustained any material loss or interference
     with their respective businesses or properties from fire, flood, hurricane,
     accident or other calamity, whether or not covered by insurance, or from
     any labor dispute or any legal or governmental proceeding, and there has
     not been any material adverse change, or any development involving a
     prospective material adverse change, in the condition (financial or
     otherwise), management, business prospects, net worth or results of
     operations of the Company or any of its subsidiaries, except in each case
     as described in or contemplated by the Prospectus (exclusive of any
     amendment or supplement thereto).

          Stockholder in this Agreement are true and correct as if made on and
          as of the Firm Closing Date;

               (ii) to the extent that any statements or omissions are made in
          the Registration Statement, any Preliminary Prospectus, the Prospectus
          or any amendment or supplement thereto in reliance upon and in
          conformity with written information furnished to the Company by such
          Selling Stockholder specifically for use therein, the Registration
          Statement, as amended as of the Firm Closing Date, does not include
          any untrue statement of a material fact or omit to state any material
          fact necessary to make the statements therein not misleading, and the
          Prospectus, as amended or supplemented as of the Firm Closing Date,
          does not include any untrue statement of a material fact or omit to

          document, or any amendment or supplement thereto, executed by the
          Company or based upon written information furnished by or on behalf of
          the Company 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 used in
          connection with the marketing of the Securities, including without
          limitation, slides, videos, films, and 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 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 by such Underwriter
through the Representatives specifically for use therein; and PROVIDED, FURTHER,
that the Company 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 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 5A(d) and (e) of this
Agreement. This indemnity agreement will be in addition to any liability which
the Company may otherwise have. The Company will not, without the prior written
consent of the 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 Principal Selling Stockholder, severally and not jointly, agrees
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 or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon any untrue statement or alleged untrue statement made by such Principal
Selling Stockholder in Section 2(B) or (C) of this Agreement, 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 such Principal 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 


                                       29

<PAGE>   30

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 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 5A(d) and (e) of this Agreement. This indemnity agreement
will be in addition to any liability which such Principal Selling Stockholder
may otherwise have. No Principal Selling Stockholder will, without the prior
written consent of the 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.

     (c) Each Additional Selling Stockholder, severally, and not jointly, agrees
to indemnify and hold harmless the Company, each of its directors, each of its
officers who signs the Registration Statement, each Underwriter and each person
who controls the Company or any Underwriter within the meaning of the Act or the
Exchange Act and each other Additional Selling Stockholder against any losses,
claims, damages or liabilities to which the Company, any such director, officer,
such Underwriter or any 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 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 or 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 such Additional Selling Stockholder for use therein;
PROVIDED, HOWEVER, that such Additional 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 


                                       30

<PAGE>   31

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 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 5A(d) and (e) of this Agreement; 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, such Underwriter or any such controlling person in
connection with investigating or defending any such loss, claim, damage,
liability or any action in respect thereof. This indemnity agreement will be in
addition to any liability which any other Additional Selling Stockholder may
otherwise have. Each Additional Selling Stockholder will not, without the prior
written consent of the Underwriter or Underwriters purchasing, in the aggregate,
more than fifty percent (50%) of the Securities, settle or comprise 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.

     (d) Each Underwriter will, severally and not jointly, indemnify and hold
harmless the Company, each of its directors, each of its officers who signed the
Registration Statement, each Selling Stockholder and each person, if any, who
controls the Company or such Selling Stockholder within the meaning of Section
15 of the Act or Section 20 of the Exchange Act against any losses, claims,
damages or liabilities to which the Company, any such director or officer of the
Company, such Selling Stockholder or any such controlling person of the Company
or such 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 or 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 such Selling
Stockholder in connection with investigating or defending any such loss, claim,
damage, liability or any action in respect thereof. This indemnity agreement
will be in addition to any liability which such Underwriter may otherwise have.
No Underwriter will, without the prior written consent of the Company, 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 


                                       31

<PAGE>   32


hereunder (whether or not the Company is a party to such claim, action,
suit or proceeding), unless such settlement, compromise or consent includes an
unconditional release of the Company from all liability arising out of such
claim, action, suit or proceeding.

     (e) 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 reasonably 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 reasonably 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.

     (f) 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 


                                       32


<PAGE>   33



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
Stockholders on the one hand and the Underwriters on the other shall be deemed
to be in the same proportion as the total net proceeds from the offering (after
discounts but before deducting expenses) received by the Company and the Selling
Stockholders 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 Stockholders or the
Underwriters, the parties' relative intents, knowledge, access to information
and opportunity to correct or prevent such statement or omission, and any other
equitable considerations appropriate in the circumstances. The Company, the
Selling Stockholders 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(f) 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 any
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
such Selling Stockholder, as the case may be.

     (g) Notwithstanding anything in this Agreement to the contrary, the
liability of each Principal Selling Stockholder under this Agreement 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
Principal 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 (less underwriting discounts and commissions but not expenses) sold
by the Principal Selling Stockholder to the Underwriters.

     9. DEFAULT OF UNDERWRITERS. If one or more Underwriters default in their
obligations to purchase Firm Securities or Option Securities hereunder and the
aggregate 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 Stockholders and the several Underwriters set forth in this Agreement or
made by or on behalf of them, respectively, pursuant to this Agreement shall
remain in full force and effect, regardless of (i) any investigation made by or
on behalf of the Company, any of its officers or directors, the Selling
Stockholders, 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
and 8 hereof shall remain in full force and effect, regardless of any
termination or cancellation of this Agreement.

     11. TERMINATION. (a) This Agreement may be terminated with respect to the
Firm Securities or any Option Securities in the sole discretion of the
Representatives by notice to the Company and the Selling Stockholders given
prior to the Firm Closing Date or the related Option Closing Date, respectively,
in the event that the Company or any of the Selling Stockholders shall have
failed, refused or been unable to perform all obligations and satisfy all
conditions on their respective parts 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,


                                       34

<PAGE>   35

               (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 respective businesses or properties from fire,
          flood, hurricane, accident or other calamity, whether or not covered
          by insurance, or from any labor dispute or any legal or governmental
          proceeding or there shall have been any material adverse change, or
          any development involving a prospective material adverse change
          (including without limitation a change in management or control of the
          Company), in the condition (financial or otherwise), business
          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);

               (ii) trading in the Common Stock shall have been suspended by the
          Commission or the New York Stock Exchange or the Nasdaq National
          Market;

               (iii) trading in securities generally on the New York Stock
          Exchange or Nasdaq National Market shall have been suspended or
          minimum or maximum prices shall have been established on either such
          exchange or market system; or a banking moratorium shall have been
          declared by New York or United States authorities; or

               (iv) there shall have been (A) an outbreak or escalation of
          hostilities between the United States and any foreign power, (B) an
          outbreak or escalation of any other insurrection or armed conflict
          involving the 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 U.S. financial markets that, in the
          sole judgment of the Representatives, makes it impractical or
          inadvisable to proceed with the public offering or the delivery of the
          Securities as contemplated by the Registration Statement, as amended
          as of the date hereof.

          (b) Termination of this Agreement pursuant to this Section 11 shall be
without liability of any party to any other party except as provided in Section
10 hereof.

          12. INFORMATION SUPPLIED BY UNDERWRITERS. The statements set forth in
the last paragraph on the front cover page and under the heading "Underwriting"
in any Preliminary Prospectus or the Prospectus (to the extent such statements
relate to the Underwriters) constitute the only information furnished by any
Underwriter through the Representatives to the Company or any Selling
Stockholder for the purposes of Sections 2(A)(b) and 8 hereof. The Underwriters
confirm that such statements (to such extent) are correct.

          13. DEFAULT BY SELLING STOCKHOLDERS. If on the Firm Closing Date or
the Option Closing Date any Selling Stockholder fails to sell the Firm
Securities or Option Securities which such Selling Stockholder has agreed to
sell on such date as set forth in SCHEDULE III hereto or Section 3(b) hereof,
the Company agrees that it will sell or arrange for the sale of at least 10% of
that number of shares of Common Stock to the Underwriters which represents Firm
Securities or Option Securities which such Selling Stockholder has failed to so
sell, as set forth in SCHEDULE III 


                                       35
