                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by the more detailed
information and Consolidated Financial Statements and Notes thereto appearing
elsewhere in this Prospectus, including information under "Risk Factors." Unless
otherwise specified, all information contained in this Prospectus assumes that
the Underwriters' over-allotment option and outstanding options and warrants to
purchase in the aggregate 648,068 shares of Common Stock will not be exercised.
Unless the context indicates otherwise, BTG, Inc. and its subsidiaries are
collectively referred to as "BTG" or the "Company." References herein to the
"Government" are to the Federal Government of the United States and its
departments, agencies and offices, including the U.S. Mission to the North
Atlantic Treaty Organization ("NATO") Consultation, Command and Control Agency.
 
                                  THE COMPANY
 
     BTG is an information technology company providing complete solutions to a
broad range of complex systems and product needs of the Government, state and
local governments and commercial clients. The Company provides systems
development, integration, engineering and network design, implementation and
security expertise services (its "Systems Business"). The Company also resells
computer hardware, software and integrated systems (its "Product Reselling
Business"). According to Federal Sources, Inc., an independent market research
firm specializing in the federal market, the Government is expected to spend
over $26 billion in fiscal 1997 on information technology services and products.
In addition, the Electronic Industries Association, a major industry trade
association, estimates that Government agencies that are not required to report
their information technology expenditures, including the intelligence community,
will spend an additional $20 billion in the Government's fiscal 1997 on such
technology. Through acquisitions, internal growth and successful contract
awards, the Company has increased its participation as a significant provider of
information technology solutions to the Government. The Company intends to
continue to expand and diversify its Government client base and to pursue other
opportunities for commercial application of its expertise. For fiscal 1996 and
the six months ended September 30, 1996, the Company's revenues were $213.6
million and $190.6 million, respectively, and its net income was $3.0 million
and $2.8 million, respectively.
 
     The Company's Systems Business specializes in network planning, design,
implementation, and support; client/server architecture for platform migration;
design and development of Internet/intranet applications; and large volume
document management and imaging applications for search and retrieval for a
variety of Government and commercial clients. Using leading edge technologies,
the Company designs, develops and integrates command, control, communications
and intelligence systems that provide open, modular computer-based solutions for
specific military applications, including information warfare. The Company uses
either commercial, off-the-shelf ("COTS") software and hardware from multiple
providers or custom-built systems to service its clients. BTG provides data
fusion systems that accept, analyze and display electronic data from land-,
sea-, air- and space-based sensors. The Company also designs proprietary
products for environmental management, cost modeling and project planning, and
furnishes a variety of services to accomplish the integration and continuing
support of its systems. In fiscal 1996 and for the six months ended September
30, 1996, revenues from Systems Business activities were 31.4% and 26.0%,
respectively, of the Company's total revenues.
 
     The Company's Product Reselling Business provides clients with advanced
technology products in the areas of enterprise networking, the UNIX operating
system environment, data storage, image processing and high-performance
client/servers. The Company has established relationships with over 200
providers of information technology products, including Compaq Computer
Corporation ("Compaq"), Dell Computer Corp. ("Dell"), Digital Equipment Corp.
("Digital"), Ingram Industries, Inc. ("Ingram") and Toshiba America Information
Systems, Inc. ("Toshiba"). These relationships provide access, at favorable
prices, to a wide variety of advanced technological products. The Company
maintains a number of contract vehicles, including a variety of large,
agency-specific contracts and four General Services Administration ("GSA")
Schedule contracts to facilitate its sales to the Government. In fiscal 1996 and
the six months ended
 
                                        3
<PAGE>   5
 
September 30, 1996, revenues from Product Reselling Business activities were
68.6% and 74.0%, respectively, of the Company's total revenues.
 
     The Company's key strategies are the following:
 
     - LEVERAGE COMPLEMENTARY BUSINESSES.  The Company will continue to leverage
       the core competencies of its Systems Business, including its expertise in
       the areas of information warfare, intelligence systems, cost modeling and
       simulation and local and wide area network design, implementation and
       management, with the procurement capabilities of its Product Reselling
       Business to provide complete information technology solutions.
 
     - PURSUE STRATEGIC ACQUISITIONS.  The Company will seek additional
       opportunities to acquire companies with complementary technical
       capabilities, new geographic locations, or clients in new markets. During
       the last four years, the Company has made four such acquisitions. The
       Company believes that continued consolidation within the information
       technology industry will provide further opportunities to expand through
       acquisitions.
 
     - USE TEAMING RELATIONSHIPS.  The Company is building teaming relationships
       with other major participants in the information technology industry that
       will enhance its ability to participate in increasingly large and complex
       procurement programs. The Company seeks to generate increased revenue and
       profitability from these relationships.
 
     - DIVERSIFY SYSTEMS BUSINESS TOWARDS NON-DEFENSE CLIENTS.  The Company will
       seek to extend its expertise in systems integration and networking beyond
       its traditional defense intelligence client base. The Company will use
       its capabilities in open systems development, networking, client-server
       architecture, and document imaging and management, together with its
       access to COTS hardware/software products, to expand its growing civilian
       government and commercial business bases.
 
     - LEVERAGE EXPERTISE WITH LEADING EDGE TECHNOLOGIES.  The Company will
       leverage its expertise with leading edge technologies to provide creative
       solutions for complex systems integration and networking requirements.
       The Company will use its skills in large scale document imaging,
       information management and data retrieval, Internet/intranet applications
       and network security and encryption technology to expand the solutions it
       offers. In order to maximize its ability to offer complete solutions, the
       Company will also continue to develop strategic alliances with leading
       edge information technology suppliers and to assemble custom,
       high-performance microcomputers and servers under its own trade name.
 
     The Company believes that through these strategies it will meet its
objective of providing responsive and high-quality products, services and
solutions that meet the complete information technology needs of a growing and
increasingly diversified client base.

                                  RISK FACTORS
 
     This Prospectus contains certain forward-looking statements within the
meaning of Section 27A of the Securities Act of 1933 and Section 21E of the
Securities Exchange Act of 1934. These statements include, among others,
statements regarding trends, opportunities and growth projections in the
information technology industry (see "Prospectus Summary -- The Company,"
"Business -- Industry Background" and "Business -- Strategy"), statements
regarding the Company's ability to continue to acquire and maintain government
contracts (see "Business -- Government Contracts"), statements regarding the
availability and exclusivity of suppliers (see "Business -- Suppliers"),
statements regarding contract backlogs (see "Business -- Backlog"), statements
regarding the Company's ability to team with major Government contractors (see
"Business -- Teaming Relationships"), statements regarding the availability of
additional financing (see "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Liquidity and Capital Resources"),
statements regarding future competition (see "Business -- Competition"),
statements concerning the nature of applicable regulatory restrictions and
limitations (see "Business -- Certain Regulatory Matters"), and statements
regarding the ability of the Company to retain key employees (see "Business --
Employees" and "-- Sales and Marketing"). Actual results could differ materially
from those projected in the forward-looking statements as a result of certain
uncertainties set forth below and elsewhere in this Prospectus. An investment in
the securities offered hereby involves a high degree of risk. Prospective
investors should carefully consider the following factors, in addition to the
other information contained in this Prospectus, in connection with investments
in the shares of Common Stock offered hereby.
 
     DEPENDENCE ON THE GOVERNMENT MARKET.  Approximately 86%, 91%, 90% and 90%
of the Company's total revenues in fiscal 1994, 1995, 1996 and in the six months
ended September 30, 1996, respectively, were derived from contracts or
subcontracts with the Government. The Company believes that the success and
development of its business will continue to be dependent upon its ability to
participate in Government contract programs. Accordingly, the Company's
financial performance may be directly affected by changes in Government
contracting policies. Among the factors that could materially adversely affect
the Company's Government contracting business are budgetary constraints, changes
in fiscal policies or available funding, changes in government programs or
requirements, including curtailment of the Government's use of technology
services firms, the adoption of new laws or regulations, technological
developments and general economic conditions. For example, the partial shutdown
of certain Government departments and agencies in the quarter ended December 31,
1995, as a result of budget negotiations between Congress and the
Administration, had an adverse effect on the Company's revenues and earnings for
that quarter and fiscal 1996. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Fiscal 1996 Compared with
Fiscal 1995."
 
     Approximately 65%, 66%, 55% and 31% of the Company's total revenues in
fiscal 1994, 1995 and 1996 and in the six months ended September 30, 1996,
respectively, were derived from contracts with the Department of Defense ("DoD")
and other national security and defense agencies (including NATO). Total
Government defense expenditures have been decreasing and are expected to
continue to decrease primarily as a result of the reordering of budget
priorities due to the perception of a reduced military threat. These reductions
could cause U.S. defense agencies to exercise their right to terminate existing
contracts for convenience or not to exercise options to renew.
 
     The Company derives significant revenues from sales made pursuant to
certain major procurement programs awarded in the ordinary course of business.
These include its GSA Schedule and related contracts, such as the Company's
electronic computer store contract with the National Institutes of Health
("NIH"). The Company's inability to renew or replace its GSA Schedule or other
contracts could have a material adverse effect on the Company. Many Government
contracts specify maximum amounts that Government clients can purchase under the
contract ("total contract capacity"). Such total contract capacity is not
indicative of revenues which will be realized under the contract.
 
     GOVERNMENT CONTRACTING RISKS.  Government contracts, by their terms,
generally can be terminated at any time by the Government, without cause, for
the convenience of the Government. If a Government contract is so terminated,
the Company would be entitled to receive compensation for the services provided
or
 
                                        7
<PAGE>   9
 
costs incurred at the time of termination and a negotiated amount of the profit
on the contract to the date of termination. In addition, all Government
contracts require compliance with various contract provisions and procurement
regulations. The adoption of new or modified procurement regulations could
materially adversely affect the Company or increase its costs of competing for
or performing Government contracts. Any violation of these regulations could
result in the termination of the contracts, imposition of fines, and/or
debarment from award of additional Government contracts. The termination of any
of the Company's significant contracts or the imposition of fines, damages, or
suspension from bidding on additional contracts could have a material adverse
effect on the Company. Most Government contracts are also subject to
modification or termination in the event of changes in funding, and the
Company's contractual costs and revenue are subject to adjustment as a result of
audits by the Defense Contract Audit Agency ("DCAA") and other Government
auditors. The DCAA routinely audits cost-reimbursement contracts to verify that
costs have been properly charged to the Government. Further, all Government
contract awards are subject to protest by competitors. See
"Business -- Government Contracts."
 
     Approximately 77% and 82% of the Company's revenues in fiscal 1996 and in
the six months ended September 30, 1996, respectively, were derived from
Government contracts awarded through formal competitive bids. Upon expiration,
such contracts may be subjected to the competitive rebidding process. There can
be no assurance that the Company will win on any particular bid or prevail in
any ensuing legal protest. Furthermore, with respect to GSA Schedule and
indefinite delivery, indefinite quantity ("IDIQ") contracts, there can be no
assurance that price levels will not be reduced. BTG's failure to win a
significant dollar volume of such contracts could materially adversely affect
the Company.
 
     Total contract capacity is not indicative of revenues which will be
realized under a contract, since Congress usually appropriates funds for a given
program on a fiscal year basis, even though actual contract performance may take
many years. As a result, contracts typically are only partially funded at the
time of award, and additional monies are normally committed to the contract by
the procuring agency as appropriations are made by Congress in subsequent fiscal
years. In addition, certain contracts span a base year and a number of option
years. There can be no assurance that the Government will extend a contract
through its option years.
 
     The Company, in the ordinary course of its business, occasionally performs
services under contracts for which funding authorization from the Government has
either expired or not been obtained, although it does so with the expectation
that such authorization will be obtained. If authorization for additional
funding is not ultimately obtained, there is a risk that the Company would not
be fully compensated for services it had performed in anticipation of contract
authorization. The Company has not experienced material losses relating to this
practice. See "Business  -- Company Operations" and "-- Backlog" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
     The Company's Product Reselling Business activities are generally conducted
under GSA Schedule contracts and negotiated procurement contracts with IDIQ
requirements, such as the New Technologies for Office and Portable Systems
("NTOPS") contract for the United States Navy. These are unfunded procurement
vehicles, and the Government generally has no obligation to purchase other than
a minimum amount of goods or services. There can be no assurances as to the
actual level of sales that will result from such unfunded contracts. In
addition, as a percentage of contract revenue in fiscal 1996 and in the six
months ended September 30, 1996, approximately 38% and 33%, respectively, of the
Company's contracts were fixed-price or time-and-materials contracts (i.e., at
the time of initial award, the price to the end-user and/or hourly rates for
time billed are set for the duration of the contract). In the event costs for
future performance of these contracts rise unexpectedly, this could have an
adverse effect on profits from such contracts. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
     REVENUE FLUCTUATIONS BASED ON GOVERNMENT SPENDING CYCLE.  The Company's
product sales tend to be seasonal, with the Company's second and third fiscal
quarters generally accounting for the greatest proportion of revenues each year.
Revenues can fluctuate significantly based on uneven purchasing patterns under
Government GSA Schedule and IDIQ contracts as well as changes in policy or
budgetary measures that adversely affect Government contracts in general. Such
fluctuations could cause the market price for the
 
                                        8
<PAGE>   10
 
Common Stock to be volatile. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- General" and "-- Quarterly
Results."
 
     POSSIBLE STOCK PRICE VOLATILITY.  The Common Stock has been trading only
since the Company's initial public offering in December 1994. The market price
of the Common Stock could be subject to significant fluctuations in response to
variations of financial results or announcements of material events by the
Company or its competitors. Developments in the Company's industry or changes in
general conditions in the economy or in the financial markets could also
materially affect the market price of the Common Stock.
 
     DEPENDENCE ON BANK CREDIT AND LIMITATIONS ON ADDITIONAL FINANCING.  The
Company is highly dependent for working capital on its revolving credit facility
(the "Credit Facility"), interest under which is at a floating rate. Loss of the
Credit Facility or significant interest rate increases could have a material
adverse effect on the Company's business. In addition, the Company's acquisition
strategy may require substantial additional financing. The Credit Facility
contains certain covenants that restrict the ability of the Company to complete
certain acquisitions or to obtain additional financing without prior approval of
the bank lender. In addition, the purchase agreement for the Company's 12.875%
Senior Subordinated Notes due 2001 (the "Subordinated Notes") contains similar
restrictions which restrict the Company's ability to complete acquisitions or
obtain additional financing without the consent of the holders of the
Subordinated Notes. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Liquidity and Capital Resources -- Credit
Facility" and "-- Subordinated Notes."
 
     MANAGEMENT OF GROWTH AND ACQUISITIONS.  The Company's revenues have
increased in each fiscal year since its inception and in the first six months of
fiscal 1997 compared to the first six months of fiscal 1996. Continued growth
will require the Company to improve its operational, financial and management
information systems and to train and manage its employees effectively. The
Company's failure to manage growth effectively could have a material adverse
effect on the Company's results of operations. In addition, the Company's future
growth may depend upon its success in identifying suitable new businesses to be
acquired. The integration of such acquired businesses into the Company's
operations may require a disproportionate amount of management's attention and
the Company's resources. There can be no assurances that suitable acquisitions
will be available, that any new businesses will generate revenues or net income
comparable to the Company's existing businesses or that such businesses will be
integrated successfully. In addition, the Credit Facility and the Subordinated
Notes contain certain covenants restricting, among other things, acquisitions,
capital expenditures and the incurrence of additional indebtedness. Such
covenants may limit the ability of the Company to complete certain acquisitions.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources -- Credit Facility" and
"-- Subordinated Notes."
 
     COMPETITION.  The markets for the Company's services and products are
highly competitive. The Company competes with many other firms engaged in each
of the Company's functional business areas, ranging from small firms to large
multinational firms, many of which have substantially greater financial,
management and marketing resources than the Company. Other competitive factors
include quality of services, technical qualifications, past contract
performance, geographic presence, price and the availability of key professional
personnel. In addition, with Government expenditures for defense contracts
expected to continue to decline, the overall market is likely to become more
competitive. The inability to procure new contracts and retain existing
contracts would result in a reduction of Company revenue and could have a
material adverse effect on the Company's results of operations. In addition,
because the markets for the Company's products and services are competitive, the
Company has experienced downward pressure on gross and operating profits as a
percentage of revenues. The Company believes that it is likely that these
competitive conditions and the commensurate pressure on margins will continue in
the future.
 
     As a non-manufacturing reseller, the Company must continue to obtain
products at competitive prices from leading suppliers in order to provide a
centralized source of price-competitive products for its clients and to be
awarded Government contracts. Although the Company believes its relationships
with its key suppliers are good, a decision by one or more to sell directly to
the Government (especially if at significantly lower prices than those of the
Company), to sell their products to the Company's competitors on more favorable
 
                                        9
<PAGE>   11
 
terms than to the Company, to allow additional resellers to represent their
products on GSA Schedule or IDIQ contracts, to restrict or terminate the
Company's rights to sell their products or to restrict their products from being
carried on GSA Schedule or IDIQ contracts could materially adversely affect the
Company's results of operations. See "Business -- Suppliers" and
"-- Competition."
 
     DEPENDENCE ON CO-CONTRACTORS.  In recent years, the Government has made use
of fewer, but larger-scale procurements to meet its information technology
requirements. This has led to an increase of teaming agreements among providers
of information technology services and products in order to make use of the
greater resources of such co-contractors to fulfill the requirements of the
larger procurements. The inability of the Company to enter into successful
teaming agreements with other Government contractors could materially adversely
affect the Company's ability to compete successfully for future Government
procurements. In addition, approximately 20% of contract revenue in fiscal 1996
and 8% of contract revenue in the six months ended September 30, 1996 was
derived from subcontracts with prime contractors on Government contracts. Under
these subcontracts, the Company may be adversely affected if the prime
contractor fails to perform satisfactorily or is unable or unwilling to meet its
obligations to the Company.
 
     PROPRIETARY INFORMATION AND TECHNOLOGICAL CHANGE.  The Company believes
that its business is dependent on its technical and organizational knowledge,
practices and procedures, and that the future success of the Company is based,
in part, on its ability to keep up to date with new technological breakthroughs
and incorporate such changes in its products and services. Also, the Company has
a proprietary interest in certain of its work products, software programs,
methodologies and know-how. Although the Company seeks to protect its
proprietary information by confidentiality agreements, there can be no assurance
that these measures will prevent the unauthorized disclosure or use of the
Company's technical knowledge, practices or procedures or that others may not
independently develop similar knowledge, practices or procedures. In addition,
the Government acquires certain proprietary rights to software programs and
other products that result from the Company's services under Government
contracts or subcontracts. The Government may disclose such information to third
parties, including competitors of the Company. In the case of subcontracts, the
prime contractors also may have certain rights to such programs and products.
Any of these factors could reduce the Company's ability to maximize the
competitive value of its proprietary information.
 
     CONTROL BY EXECUTIVE OFFICERS AND DIRECTORS; ANTI-TAKEOVER PROVISIONS.  As
of September 30, 1996 and after giving effect to this offering, the Company's
executive officers and directors will own beneficially approximately 24.4% of
the outstanding Common Stock (approximately 23.7% if the Underwriters' over-
allotment options are exercised in full). In addition, Dr. Edward H. Bersoff and
his wife, Ms. Marilynn D. Bersoff, will own approximately 17.2% of the
outstanding Common Stock (approximately 16.8% if the Underwriters'
over-allotment options are exercised in full). Consequently, Dr. Bersoff alone
and the executive officers and directors as a group will be able to exert
significant influence over corporate matters requiring shareholder approval,
including the election of directors. This influence, together with applicable
statutory provisions under Virginia law and certain measures included in the
Company's Amended and Restated Articles of Incorporation, including the ability
of the Board of Directors to issue one or more series of preferred stock without
shareholder approval, the election of directors in three classes on a staggered
basis and the requirement of super-majority shareholder approval to remove
directors, could deter or delay unsolicited changes in control of the Company.
See "Principal and Selling Shareholders" and "Description of Capital
Stock -- Virginia Anti-Takeover Provisions" and "-- Certain Provisions of the
Amended and Restated Articles of Incorporation." In addition the Credit Facility
and the Subordinated Notes contain covenants restricting changes of control of
the Company without the holders consent. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources -- Credit Facility" and "-- Subordinated Notes."
 
     DEPENDENCE ON KEY MANAGEMENT PERSONNEL.  The Company's success depends to a
significant extent on its key management personnel. The only member of executive
management who is subject to an employment agreement is Dr. Bersoff, the
President and Chief Executive Officer of the Company. The Company has obtained
"key-man" insurance with respect to Dr. Bersoff in the amount of $1.5 million.
The loss of any of the Company's existing key executive personnel, including Dr.
Bersoff, could have a material adverse effect on the Company's financial
position and results of operations. See "Business -- Employees" and
"Management."

     RECRUITMENT AND RETENTION OF KEY TECHNICAL PERSONNEL.  The Company's
success depends to a significant extent on its ability to recruit and retain key
technical personnel. Competition for technical personnel in the information
technology services industry is intense, and the Company must often comply with
provisions in Government contracts which require employment of persons with
specified levels of education, work experience and security clearances. The loss
of the Company's existing key technical personnel or the inability to attract
and retain key employees in the future or to relocate such personnel on certain
contracts performed at remote locations could have a material adverse effect on
the Company's results of operations. See "Business -- Employees" and
"Management."
 
     REQUIREMENT TO MAINTAIN SECURITY CLEARANCES.  As of September 30, 1996, 37%
of the Company's employees have security clearances that permit the Company to
obtain and perform classified work under certain Government contracts. In
addition, many of the Company's Government contracts require the Company to
maintain facility security clearances complying with DoD and other requirements.
If the Company were to lose these clearances, the Company might not be able to
retain such contracts, and, if present clearances were invalidated, it might not
be able to obtain new contracts requiring security clearances.
 
     NO DIVIDENDS.  The Company intends to retain future earnings, if any, for
use in its business and does not anticipate declaring or paying any cash
dividends on shares of its Common Stock in the foreseeable future. In addition,
the Company is restricted under the terms of the Credit Facility and the
Subordinated Notes from declaring or paying cash dividends on its Common Stock.
See "Dividend Policy" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Liquidity and Capital Resources -- Credit
Facility" and "-- Subordinated Notes."
 
     SHARES ELIGIBLE FOR FUTURE SALE.  Sales of substantial amounts of Common
Stock in the public market after this offering may have an adverse effect on the
market price of the Common Stock. The Company, its directors, its executive
officers and the Selling Shareholder have agreed not to sell or otherwise
dispose of any shares of Common Stock held by them, other than the shares being
sold hereunder by the Selling Shareholder, for a period of 120 days after the
date of this Prospectus without the consent of Prudential Securities
Incorporated on behalf of the Underwriters, subject to certain limited
exceptions. Upon expiration of this period, of the 7,843,782 shares outstanding,
4,741,895 shares will be freely tradeable. In addition, 1,335,081 shares will be
held by "affiliates" as that term is defined in Rule 144 under the Securities
Act of 1933, as amended (the "Securities Act"). An additional 1,766,806 shares
of the Common Stock will be deemed to be "restricted securities" pursuant to
Rule 144 under the Securities Act. Upon the expiration of the 120-day lock-up
period, all of these "restricted securities" and shares held by "affiliates"
will be immediately eligible for sale in the public market in reliance upon Rule
144, subject to volume and other restrictions contained therein. See "Shares
Eligible for Future Sale."

                                USE OF PROCEEDS
 
     The net proceeds from the sale by the Company of 1,670,000 shares of Common
Stock offered hereby are estimated to be approximately $26.0 million ($29.8
million if the Underwriters' over-allotment options are exercised in full),
after deducting underwriting discounts and commissions and estimated offering
expenses payable by the Company, at an assumed offering price of $16.88 per
share (the last reported sales price of the Common Stock on the Nasdaq National
Market on October 22, 1996). The Company will not receive any proceeds from the
sale of shares of Common Stock by the Selling Shareholder.
 
     The Company plans to use all of the net proceeds to reduce borrowings
outstanding under the Credit Facility as of the consummation of this offering.
The Credit Facility has been used to fund the acquisition of Concept Automation,
Inc. of America ("CAI") (approximately $14.7 million) and for general working
capital purposes. As of September 30, 1996, borrowings under the Credit Facility
were $50.5 million. Following the application of the net proceeds of the
offering, the Company will have an outstanding balance under the Credit Facility
of approximately $24.5 million. The Credit Facility expires on August 31, 1998
and bears interest, at the option of the Company (with certain limitations), at
either (i) the NationsBank, N.A. prime rate or (ii) LIBOR plus (A) 2.00% if, at
the time of election, the Company has in place at least $15.0 million of fully
funded subordinated debt, or (B) 2.25% if, at the time of election, such
subordinated debt is not in place. The weighted average interest rate under the
Credit Facility was approximately 7.49% during the six months ended September
30, 1996. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Liquidity and Capital Resources -- Credit Facility."

(1) In June 1992, the Company acquired all the outstanding common stock of BDS.
    In July and November 1994, the Company acquired all of the outstanding
    common stock of ACTech and Delta, respectively. The acquisitions were
    accounted for as purchases and, accordingly, the results of their operations
    have been included in the Company's consolidated financial statements from
    the dates of acquisition. See Note 11 of Notes to Consolidated Financial
    Statements.
(2) In October 1995, the Company acquired all of the outstanding common stock of
    CAI. This acquisition was accounted for as a purchase and, accordingly, the
    results of operations for CAI have been included in the Company's
    consolidated financial statements from the date of acquisition. See Note 11
    of Notes to Consolidated Financial Statements.
(3) These results assume that (i) the acquisition of CAI, (ii) the sale by the
    Company of 1,670,000 shares of Common Stock offered hereby at an assumed
    offering price of $16.88 per share, and (iii) the elimination of interest
    expense on Company borrowings to be repaid with the net proceeds of this
    offering had occurred at the beginning of the period. See Unaudited Pro
    Forma Condensed Consolidated Financial Statements.
(4) Assumes the sale by the Company of 1,670,000 shares of Common Stock offered
    hereby at an assumed offering price of $16.88 per share and the elimination
    of interest expense on Company borrowings to be repaid with the net proceeds
    of this offering had occurred at the beginning of the period. See Unaudited
    Pro Forma Condensed Consolidated Financial Statements.
(5) In fiscal 1994, amortization and other operating costs included a write off
    of $397,000 for goodwill relating to a previously acquired subsidiary which
    has ceased operations. See Note 10 of Notes to Consolidated Financial
    Statements of BTG.
(6) Equity in earnings of affiliates in fiscal 1996 and the six months ended
    September 30, 1996 relates to the Company's 49% interest in an
    unincorporated joint venture which is accounted for using the equity method.
    See Note 10 of Notes to Consolidated Financial Statements.
(7) Discontinued operations in fiscal 1992 relates to the discontinued
    operations of an 80%-owned subsidiary engaged in the development of an
    imaging and document management product.
(8) Fully diluted earnings per share are substantially the same as primary
    earnings per share for the years presented. The Company has never declared
    or paid cash dividends on its capital stock and no cash dividends are
    presently contemplated.
(9) The significant increase in working capital from March 31, 1995 to March 31,
    1996 is primarily attributable to the Company's new Credit Facility, which
    was entered into in November 1995 and to the Subordinated Notes, both of
    which represent noncurrent debt. See "Management's Discussion and Analysis
    of Financial Condition and Results of Operations -- Credit Facility" and
    "-- Subordinated Notes." Borrowings under the Company's previous line of
    credit facility were of a short-term nature, and all such borrowings have
    been repaid.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
GENERAL
 
     BTG is an information technology company providing complete solutions to a
broad range of complex systems and product needs of the Government, state and
local governments and commercial clients. The Company has grown significantly
during the last four years in part through the acquisition of four companies:
BDS, Inc. ("BDS") (June 1992), Advanced Computer Technology, Inc. ("ACTech")
(July 1994), Delta Research Corporation ("Delta") (November 1994), and CAI
(October 1995).
 
     The Company's revenues are derived from contract activities of the Systems
Business and from product sales of the Product Reselling Business. Contract
revenue is typically less seasonal than product sales but fluctuates
month-to-month based on contract delivery schedules. Contract revenue is
characterized by lower direct costs than product sales, yet generally requires a
higher relative level of infrastructure support. Year-to-year increases in
contract revenue have generally resulted from increases in volume, driven by
additional work requirements under Government contracts, rather than price
increases, which are generally limited to escalation factors of 3% to 4% on
direct labor costs. Product sales tend to be seasonal, with the Company's second
and third fiscal quarters typically accounting for the greatest proportion of
revenue each year. Product sales are characterized by higher direct costs than
contract revenue; however, indirect expenses associated with product sales are
generally lower in comparison. Year-to-year increases in product sales have
generally been driven by higher volumes as opposed to price increases, because
hardware and software product prices tend to decline over time as the technology
matures and some segments of the Company's products business are subject to
intense price competition.
 
     During fiscal 1996, the Company's operations were adversely affected by the
Government's budget impasse, which resulted in partial shutdowns of the
Government for several weeks during the Company's third and fourth fiscal
quarters. These shutdowns had a negative impact on fiscal third quarter
operations. In addition, the processing of payments under Government contracts
and purchases was delayed by the shutdowns. This required the Company to carry
higher receivable balances, which, in turn, resulted in higher interest costs.
The extent of any impact on the Company's results of operations, financial
position or liquidity resulting from possible future shutdowns cannot be
determined at this time.
 
     In October 1995, the Company acquired all of the outstanding capital stock
of CAI for approximately $14.7 million. CAI was primarily involved in the
integration, sale and maintenance of electronic data processing equipment and
related support services, principally to civilian agencies of the Government.
The acquisition was accounted for using the purchase method of accounting, and
accordingly, the results of operations of CAI have been included in the
Company's consolidated statement of operations since the date of acquisition.
The excess of the purchase price over the fair value of the net tangible and
identifiable intangible assets acquired, or approximately $11.5 million, has
been recorded as goodwill and is being amortized on a straight-line basis over
the expected period of benefit, 20 years. In connection with the acquisition,
the Company also entered into both non-compete and employment agreements with
several members of CAI's senior management. In connection with the acquisition,
the Company agreed to pay the former shareholders of CAI a percentage of the
Company's gross profits realized from the NTOPS contract.

</TABLE>
 
  SIX MONTHS ENDED SEPTEMBER 30, 1996 COMPARED WITH SIX MONTHS ENDED SEPTEMBER
30, 1995
 
     Revenues for the six months ended September 30, 1996 increased by $100.2
million, or 111.0%, from the six months ended September 30, 1995. Of this
increase, $20.9 million was attributable to contract revenue, and $79.3 million
was attributable to product sales. The increase in contract revenue in the six
months ended September 30, 1996 was primarily due to $10.3 million of revenue
recognized under contracts acquired in connection with the acquisition of CAI in
October 1995; $7.9 million of revenue recognized under the Company's Integration
for Command, Control, Communications, Computers and Intelligence ("IC4I")
contract which was awarded to the Company in November 1995; and an aggregate
$2.7 million in net increases under a variety of other contracts. The increase
in product sales was primarily due to approximately $44.4 million of revenue
generated under a variety of sales vehicles acquired in connection with the
acquisition of CAI; $47.1 million of revenue resulting from sales under the
Company's electronic computer store contract with the NIH; $11.8 million in
increased sales under GSA Schedule contracts, either directly from the Company's
GSA Schedule contracts or from sales to other prime contractors with GSA
Schedule contracts; and $200,000 in net increased revenues under a variety of
other sales vehicles. These increases were offset by a decrease of approximately
$23.3 million in sales from purchase contracts under the Company's NATO Basic
Ordering Agreement ("BOA") and a decrease of approximately $900,000 in orders
fulfilled under the Systems Acquisition Support Services ("SASS") contract. In
the six months ended September 30, 1996, approximately 89.6% of the Company's
revenues were derived from contracts or subcontracts with and product sales to
the U.S. Government and its agencies, as compared with 89.4% in the six months
ended September 30, 1995.
 
     Direct costs, expressed as a percentage of total revenue, increased to
80.5% in the six months ended September 30, 1996 from 74.8% in the six months
ended September 30, 1995, reflecting the increased
 
                                       18
<PAGE>   20
 
proportion of total revenues derived from product sales, which typically have
higher direct costs than do revenues generated from service contracts. Contract
costs as a percentage of contract revenue increased to 60.7% in the six months
ended September 30, 1996 from 50.3% in the six months ended September 30, 1995,
primarily as a result of revenues generated from the IC4I contract and from
contracts acquired in connection with the acquisition of CAI. Both the IC4I
contract and the contracts acquired from the acquisition of CAI require higher
levels of material purchases and/or subcontractor involvement than does BTG's
historical contract base, which has a more labor intensive, higher gross margin
profile. Contract costs include labor costs, subcontract costs, material costs
and other costs directly related to contract revenue. Cost of product sales as a
percentage of product sales increased to 87.4% in the six months ended September
30, 1996 from 86.0% in the six months ended September 30, 1995. This reflects
the different mix of products sold during the six months ended September 30,
1996 as compared to the comparable period of the prior year.
 
     Indirect, general and administrative expenses include the costs of indirect
labor, fringe benefits, overhead, sales and administration, bid and proposal,
and research and development. Indirect, general and administrative expenses
increased by $11.7 million, or 66.4%, for the six months ended September 30,
1996 as compared with the same period in the previous year. The increase was due
primarily to indirect expenses incurred by CAI, which were not included in the
six months ended September 30, 1995 since CAI was not acquired until October
1995, as well as from an increase in the overall volume of business as compared
to the comparable period of the prior year. Expressed as a percentage of total
revenues, indirect, general and administrative expenses decreased for the six
months ended September 30, 1996 to 15.5% from 19.6% in the six months ended
September 30, 1995. This decrease reflects both the significant growth in
revenue generated from product sales, which typically requires less
infrastructure support than does contract revenue, and the acquisition of CAI,
which has historically required a relatively lower level of indirect costs to
support its revenues.
 
     Amortization and other operating costs, which include amortization expense
associated with goodwill and other intangible assets and other operating
expenses which are non-reimbursable under Government contracts, increased by
$365,000, or 62.5%, for the six months ended September 30, 1996 as compared with
the same period in the previous year. This increase is primarily attributable to
the amortization expense associated with the goodwill and other intangible
assets created as a result of the acquisition of CAI in October 1995.
 
     Interest expense increased by $1.8 million, or 152.7%, for the six months
ended September 30, 1996 as compared with the same period in the previous year.
This increase was due in large part to the significant growth in revenue during
the six months ended September 30, 1996 as compared with the comparable period
of the prior year, as well as the higher volume of product orders projected for
the quarterly period ending December 31, 1996, both of which have resulted in
higher receivable, inventory and prepaid expense balances, thereby resulting in
higher levels of required financing under the Company's line of credit. In
addition, higher interest costs were incurred during the six months ended
September 30, 1996 due to interest paid on borrowings related to the Company's
acquisition of CAI in October 1995, and the higher interest rate associated with
the Subordinated Notes.
 
     Equity in earnings of affiliate was $1.1 million during the six months
ended September 30, 1996, and resulted from the Company's interest in an
unincorporated joint venture. The joint venture entity, which is with an
unrelated company, was created for the purpose of performing under a specific
contract and was acquired by the Company in connection with its acquisition of
CAI.
 
     The Company's effective tax rate increased from 41.7% for the six months
ended September 30, 1995 to 44.2% for the six months ended September 30, 1996.
This increase is primarily attributable to the additional goodwill and
intangible asset amortization expense associated with the acquisition of CAI,
which is not deductible for income tax purposes.
 
     Net income for the six months ended September 30, 1996 increased by
$785,000, or 39.9%, from the six months ended September 30, 1995, due to the
reasons discussed above.

  FISCAL 1996 COMPARED WITH FISCAL 1995
 
     Revenues for fiscal 1996 increased by $57.6 million, or 36.9%, from fiscal
1995. Of this increase, $20.9 million was attributable to contract revenue,
which increased by 45.3%, and $36.7 million was attributable to product sales,
which increased by 33.4%. The increase in contract revenue was primarily due to
revenue of $7.7 million recognized by CAI, which was acquired in October 1995;
an increase of $7.5 million in revenue recognized from a full year's operations
of Delta, which was acquired in November 1994; and $4.9 million in sales of
Internet-related services. The increase in product sales was primarily due to
sales of $17.6 million recognized by CAI; $20.0 million in sales to prime
contractors of the Government under a variety of contract vehicles; $9.7 million
in increased sales from direct DoD orders; $4.8 million in orders fulfilled
under the SASS contract for the defense intelligence community; and $900,000 in
increased sales to the commercial market. These increases were offset by
decreases of $10.7 million in sales from purchase contracts under the NATO BOA
and $6.3 million in decreased sales under the Company's GSA Schedule contracts,
the latter of which the Company believes was in large part attributable to the
Government's budget impasse during fiscal 1996. In fiscal 1996, approximately
89.8% of the Company's revenue was derived from contracts or subcontracts with
and product sales to the Government, as compared with 91.2% for fiscal 1995.
 
     Direct costs, expressed as a percentage of total revenue, increased to
76.6% in fiscal 1996 from 76.1% in fiscal 1995. Contract costs as a percentage
of contract revenue increased to 53.1% in fiscal 1996 from 50.0% in fiscal 1995,
primarily as a result of revenue generated from CAI's contracts, which typically
required higher levels of material purchases than BTG's historical contract
base, which has a more labor intensive, higher gross margin profile. Contract
costs include labor costs, subcontract costs, material costs, and other costs
directly related to contract revenue. Cost of product sales as a percentage of
product revenue increased slightly to 87.4% in fiscal 1996 from 87.0% in fiscal
1995. This increase was primarily attributable to the inclusion of CAI's product
sales, which generated lower gross margins for the year than the Company has
typically experienced in its other product sales business.
 
     Indirect, general and administrative expenses include the cost of indirect
labor, fringe benefits, overhead, sales and administration, bid and proposal,
and research and development expenses. Indirect, general and administrative
expenses increased by $11.4 million, or 38.9%, in fiscal 1996 as compared with
fiscal 1995. Expressed as a percentage of total revenue, indirect general and
administrative expenses increased slightly in fiscal 1996 to 19.1%, from 18.8%
in fiscal 1995. This increase was due primarily to indirect expenses of $5.3
million at CAI and a net increase in indirect expenses of $3.6 million at Delta,
which was acquired during the latter half of fiscal 1995. These increases were
offset by decreased bid and proposal costs of $1.2 million in fiscal 1996 as
compared with fiscal 1995. The remainder of the increase is primarily
attributable to an increase in the overall volume of business and to higher
indirect costs resulting from compensation paid to a number of employees who
could not be charged as direct labor costs to federal contracts affected by the
Government shutdowns.
 
     Amortization and other operating costs, which include the amortization of
goodwill and other intangible assets as well as other operating expenses which
are non-reimbursable under Government contracts, increased by $525,000, or
49.1%, in fiscal 1996 as compared with fiscal 1995. This increase was largely
attributable to $394,000 of additional amortization expense associated with
goodwill and other intangible assets arising from the business combinations made
by the Company in fiscal 1996 and the latter half of fiscal 1995. The remaining
increase is attributable to additional non-reimbursable operating costs incurred
principally as a result of the overall increase in the Company's business and
from unconsummated merger and acquisition transactions.
 
     Interest expense increased by $1.7 million, or 123.6%, in fiscal 1996 as
compared with fiscal 1995. This increase was due in large part to interest paid
on borrowings related to the Company's acquisition of ACTech, Delta, and CAI in
fiscal 1995 and 1996. In addition, the growth in revenue in fiscal 1996
generated an increase in receivable balances, thereby resulting in a higher
level of interest expense related to receivable financing. Further, the
Government shutdowns during the third and fourth quarters of fiscal 1996 delayed
the processing of payments under Government contracts and purchases. This
required the Company to carry its outstanding receivable accounts for longer
periods of time than would otherwise have been the case, which, in turn,
resulted in higher interest costs to the Company. In November 1995, the Company
entered into the Credit
 
                                       20
<PAGE>   22
 
Facility, a revolving line which is primarily used to fund ongoing operations of
the Company. Interest paid under the Credit Facility is based on current market
rates adjusted monthly. The average interest rate incurred under the Credit
Facility during fiscal 1996 was 8.1%, as compared with 7.9% in fiscal 1995. The
increase in the average interest rate paid reflects the higher rate payable
under the formula set forth in the Credit Facility as compared with the
Company's former credit facility, partially offset by a decline in prevailing
market rates during fiscal 1996.
 
     The Company's effective tax rate for fiscal 1996 was 43.6% compared to
43.4% in fiscal year 1995. The increase is due to the additional goodwill and
intangible asset amortization expense, which typically is not deductible for
income tax purposes, offset in part by a reduction in the deferred tax asset
valuation allowance.
 
     Net income for fiscal 1996 decreased by $178,000, or 5.7%, from fiscal
1995, due to the reasons discussed above.
 
  FISCAL 1995 COMPARED WITH FISCAL 1994
 
     Revenues for fiscal 1995 increased by $52.4 million, or 50.6%, from fiscal
1994. Of this increase, $10.6 million was attributable to contract revenue, and
$41.8 million was attributable to product sales. The increase in contract
revenue was primarily due to revenue of $4.7 million recorded by Delta, which
was acquired in November 1994; $3.9 million in increased revenue recognized on
the Joint Defense Intelligence Support Services ("JDISS") contract (all of which
related to an emergency buy contract which is not expected to recur); and
approximately $1.1 million and $900,000 in increased revenue recognized on the
Constant Source Operator's Terminal ("CSOT") and Tactical Advanced Computer
Program-3 ("TAC-3") contracts, respectively. The increase in product sales in
fiscal 1995 was primarily due to an increase of $17.6 million in sales under
BTG's GSA Schedule contracts, as well as $13.1 million in orders fulfilled on
the SASS contract for the defense intelligence community, which was awarded in
July 1994. In addition, product sales increased in fiscal 1995 due to $7.2
million in revenues related to orders under the NATO BOA; $2.8 million in
product sales of ACTech, which was acquired in July 1994; and an increase of
$3.4 million in product sales to the DoD and other civilian agencies. These
increases in product sales were partially offset by a reduction of $2.3 million
in product sales to non-Government clients. In fiscal 1995, approximately 91% of
BTG's revenues were derived from contracts or subcontracts with and product
sales to the Government, as compared with 86% for fiscal 1994.
 
     Direct costs, expressed as a percentage of total revenues, increased to
76.1% in fiscal 1995 from 74.9% in fiscal 1994, reflecting the increased
proportion of total revenues accounted for by product sales, which generally
involve relatively higher direct costs, as compared to contract revenue.
Contract costs include labor, subcontract, materials and other costs directly
related to contract revenues. Contract costs as a percentage of contract revenue
increased from 48.7% in fiscal 1994 to 50.0% in fiscal 1995, primarily due to
the increased costs of materials in fulfilling the JDISS emergency buy contract,
which included significant equipment deliveries. Cost of product sales as a
percentage of product sales decreased from 88.6% in fiscal 1994 to 87.0% in
fiscal 1995, reflecting relatively higher gross margins earned on ACTech's sales
of its high-performance personal computers and sales of COTS software products
under the SASS contract.
 
     Indirect, general and administrative expenses include the cost of indirect
labor, fringe benefits, overhead, sales and administration, bid and proposal,
and research and development expenses. Indirect, general and administrative
expenses increased by $8.5 million, or 40.9%, in fiscal 1995 as compared with
fiscal 1994. The increase was due primarily to indirect expenses of $1.9 million
at Delta, indirect expenses of $2.1 million at ACTech, $844,000 for indirect
expenses related to the SASS program, and increased bid and proposal costs of
$929,000. The remainder of the increase is due to an increase in the overall
volume of business. Expressed as a percentage of total revenues, indirect,
general and administrative expenses decreased for fiscal 1995 to 18.8% from
20.1% in fiscal 1994, due principally to the increase in revenues derived from
product sales in fiscal 1995 which, compared with contract revenue, generate a
relatively lower level of indirect, general and administrative expenses.
 
     Amortization and other operating costs, which include amortization of
goodwill and other intangible assets and other expenses which are
non-reimbursable under Government contracts, increased by $65,000, or 18.2%, in
fiscal 1995 as compared with fiscal 1994. The amount for fiscal 1994 includes
$397,000 of goodwill
 
                                       21
<PAGE>   23
 
related to a previously acquired subsidiary. Excluding the goodwill written off
in fiscal 1994, amortization and other operating costs in fiscal 1995 increased
by $562,000, or 110.6%, compared to fiscal 1994. The net increase in fiscal 1995
was largely attributable to the additional amortization of goodwill and other
intangible assets arising from the purchases of ACTech and Delta, financial
consulting expenses of $165,000 associated with the Company's then-existing
credit facility, and other internal and miscellaneous acquisition expenses of
approximately $90,000.
 
     Interest expense increased by $545,000, or 66.7%, in fiscal 1995 as
compared with fiscal 1994. This increase was due in part to interest paid on
borrowings related to the acquisitions of ACTech and Delta and advances under
the Company's then-existing credit facility to fund growth in all business
areas. In addition, the growth in revenues in fiscal 1995 generated an increase
in receivable balances, thereby resulting in a higher level of interest expense
related to receivable financing. The former credit facility was used primarily
for accounts receivable and inventory financing with borrowing capacity governed
by a borrowing base formula primarily composed of eligible receivables and
inventory as defined in the former credit facility. See Note 7 of Notes to
Consolidated Financial Statements.
 
     BTG's effective tax rate for fiscal 1995 was 43.4% compared to 46.7% in
fiscal year 1994. The decrease is due to the additional goodwill write-off of
$397,000 in fiscal 1994 (see discussion above), which typically is not
deductible for income tax purposes.
 
     Net income for fiscal 1995 increased by $1.3 million, or 72.3%, from fiscal
1994, due to the reasons discussed above.
 
  QUARTERLY RESULTS
 
     The quarterly operating results for BTG's Product Reselling Business vary
depending upon such factors as the Government's purchasing schedules and the
timing of new product releases by BTG's suppliers, with BTG's second and third
fiscal quarters generally accounting for the greatest proportion of revenues
each year. Quarterly operating results for BTG's Systems Business generally
fluctuate to a lesser extent, but will vary depending upon such factors as the
Government's work requirements and changes in funding.
 
     The following table represents unaudited operating results for BTG for the
10 quarters ended September 30, 1996. This information has been prepared by BTG
on a basis consistent with its audited Consolidated Financial Statements and
includes all adjustments (consisting only of normal recurring adjustments) that
BTG considers necessary for a fair presentation in accordance with generally
accepted accounting principles. Such quarterly results are not necessarily
indicative of future results of operations.

  INFLATION
 
     Approximately 56.8% and 31.6% of the Company's contract revenue for fiscal
1996 and for the six months ended September 30, 1996, respectively, were derived
under certain IDIQ contracts or cost-reimbursement contracts, under which
inflationary increases are borne by the client. Although the Company performs on
several multi-year fixed-price, time-and-materials, and IDIQ contracts, under
which it bears the risk of inflationary pressure on its costs, to date it has
not been materially adversely affected by inflation. In addition, the Company's
product sales generally have not been affected by inflation.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Net cash of approximately $19.0 million was used in operating activities
during the six months ended September 30, 1996. This net use of cash largely
resulted from a significant increase in accounts receivable, which was due to
the revenue growth experienced by the Company during the six months ended
September 30, 1996 as compared with the comparable period of the prior year. In
addition, increases in both inventory and prepaid expenses contributed to the
net use of cash in the six months ended September 30, 1996, offset by increases
in accounts payable and accrued expenses. Operating activities during fiscal
1996 used cash of approximately $5.2 million, primarily reflecting increases in
accounts receivable of $10.9 million and decreases in accounts payable of $5.8
million, offset by decreases in prepaid expenses of $5.0 million. Net cash of
$13.3 million and $6.6 million was used by operating activities during fiscal
1995 and 1994, respectively. The cash used in operations during fiscal 1995 was
largely the result of increases in accounts receivable and inventory resulting
from higher business volumes and an increase in prepaid expenses resulting from
advance purchases under the SASS contract. Operating activities during fiscal
1995 used cash of $13.3 million compared with $6.6 million in 1994, primarily
reflecting increases in accounts receivable of $6.3 million and inventory of
$2.6 million resulting from the increased volume of business and $6.8 million in
prepaid expenses resulting from advance purchases under the SASS contract.
 
     Investing activities used cash of approximately $1.2 million during the six
months ended September 30, 1996. This was largely the result of a $200,000
investment made in WheelGroup Corporation ("WheelGroup"), which is primarily
involved in network security products and services, and a $300,000 convertible
note purchased from WheelGroup. In addition, the Company invested cash of
approximately $442,000 in the purchase of office and computer-related equipment
for use in the performance of contracts and for increased efficiency in the
Company's administration. The Company also invested cash of approximately
$297,000 in the development of software products designed for use by the
Company's newly-formed subsidiary, Community Networks, Inc. ("CNI"). CNI was
formed by the Company for the purpose of providing local communities with
high-speed Internet access, specialized intranets, and electronic commerce
capability. Investing activities used cash of approximately $15.2 million during
fiscal 1996, principally due to the acquisition of CAI. In comparison, $4.2
million and $342,000 was used by investing activities in fiscal 1995 and 1994,
respectively. The cash used in investing activities during fiscal 1995 was
principally due to the acquisitions of ACTech and Delta.
 
     During fiscal 1996, 1995, and 1994, the Company invested $1.6 million,
$734,000, and $367,000, respectively, in capital expenditures, primarily
relating to acquisitions of office and computer-related equipment for use in the
performance of contracts and for increased efficiency in the Company's
administration.
 
     During the six months ended September 30, 1996, the Company's financing
activities provided cash of approximately $20.3 million, resulting primarily
from $20.1 million in increased borrowings under the Company's revolving line of
credit used to fund working capital needs. At September 30, 1996, the Company
had approximately $9.5 million available for borrowing under its Credit
Facility. On October 1, 1996, the Credit Facility was amended to increase the
ceiling for available borrowings to $85.0 million through March 31, 1997 and
$65.0 million thereafter. During fiscal 1996, $19.1 million was provided from
financing activities primarily as the result of $15.0 million in proceeds
received from the issuance of the Subordinated Notes and increased borrowings of
$7.0 million under the Credit Facility. See "-- Subordinated Notes" and
"-- Credit Facility." These funds were used to finance the cash portion of the
Company's acquisition of CAI and to fund the Company's significant business
growth. These financing sources were offset by the repayment of $1.6 million of
long-term debt, including amounts previously outstanding with the Company and
amounts
 
                                       23

acquired in the purchase of CAI, and the payment of $1.6 million of costs
incurred to obtain the Credit Facility and to issue the Subordinated Notes. In
fiscal 1995, $18.6 million was provided from financing activities, reflecting
$8.7 million in net proceeds from the Company's initial public offering and
increased borrowings of $11.4 million under the Company's previous line of
credit, which resulted from financing needed to fund the Company's growth. In
fiscal 1994, approximately $6.6 million was provided for financing activities,
principally from accounts receivable financing under the Company's previous line
of credit.
 
     As of September 30, 1996, working capital was $71.4 million, compared to
$47.9 million at March 31, 1996. This increase is primarily due to the
significant increase in the volume of business during the six months ended
September 30, 1996, which resulted in significantly higher accounts receivable
balances. At March 31, 1996, working capital was $47.9 million, a $34.8 million
increase over the working capital level at March 31, 1995. This increase is
primarily attributable to the Company's Credit Facility and to the Subordinated
Notes, both of which represent non-current debt. Borrowings under the Company's
previous credit facility were of a short-term nature.
 
     BTG believes that funds available under its Credit Facility and the
application of the net proceeds of this offering will be sufficient to meet the
Company's working capital and capital expenditure requirements for the next 12
months.
 
     Credit Facility.  The Credit Facility is a secured revolving credit
facility consisting of four revolving promissory notes provided to the Company
and its subsidiaries by NationsBank, N.A. ("NationsBank"), Fleet Capital
Corporation, Sanwa Business Credit Corporation, and Signet Bank, N.A.
(collectively the "Lenders") in the principal amount of up to $85.0 million.
(See, however, " -- Subordinated Notes" regarding limitations on the Company's
borrowings under the Credit Facility.) The principal amount outstanding under
the Credit Facility may not exceed the lesser of (i) $85.0 million or (ii) a
defined borrowing base, which is a variable amount calculated by aggregating a
specified set of the Company's accounts receivable, unbilled costs, and
inventory ($81.7 million as of October 14, 1996). The Company must pay a
commitment fee if the quarterly average daily outstanding principal balance
under the Credit Facility is less than 50.00% of the commitment amount ($85.0
million unless otherwise reduced). Interest on revolving loan advances made
under the Credit Facility is, at the option of the Company, either (i) the
NationsBank prime rate or (ii) LIBOR plus 2.00%. The Credit Facility is secured
and includes certain financial and other covenants restricting, among other
things, changes in capital structure, mergers, acquisitions, sales of assets,
changes of operations, purchases and redemptions of stock, additional
indebtedness, payment of dividends and other payments to shareholders,
investments, capital expenditures, a net loss by the Company for any fiscal
quarter and certain other matters without the approval of NationsBank. The
Company was in compliance with all financial covenants and ratios required under
the Credit Facility at September 30, 1996. On such date, the balance outstanding
under the Credit Facility was approximately $50.5 million. The Credit Facility
expires on August 31, 1998.
 
     Subordinated Notes.  On February 16, 1996, the Company entered into a Note
and Warrant Purchase Agreement (the "Nomura Agreement") with Nomura Holding
America, Inc. ("Nomura") under which the Company issued $15.0 million of
Subordinated Notes. The Subordinated Notes, which bear interest at 12.875% per
annum, are due in February 2001. In connection with the issuance of the
Subordinated Notes, the Company also issued common stock purchase warrants (the
"Warrants") to the holder of the Subordinated Notes, entitling such holder to
purchase up to 317,478 shares of Common Stock at $9.50 per share and to certain
registration rights with respect to such shares. The Warrants are exercisable at
any time through February 16, 2003. Both the number of shares obtainable from
exercise of the Warrants and the exercise price per share are subject to
adjustment based on certain anti-dilution provisions included in the Nomura
Agreement. The Nomura Agreement also contains certain covenants, which, among
other matters, restrict or limit the ability of the Company to pay dividends,
incur indebtedness, make capital expenditures and acquire other companies. The
Company is also required to maintain certain financial ratios regarding interest
coverage, leverage, and net worth, among others. The Company was in compliance
with all financial covenants and ratios required under the Nomura Agreement at
September 30, 1996. On October 1, 1996, the Company obtained the consent of the
Subordinated Notes holders to increase its borrowings under the Credit Facility
to $85.0 million (the Nomura Agreement originally restricted the Company from
borrowing amounts over $60.0 million from the Credit Facility) until March 31,
1997, and $65.0 million thereafter.

                                    BUSINESS
 
GENERAL
 
     BTG is an information technology company providing complete solutions to a
broad range of complex systems and product needs of the Government, state and
local governments and commercial clients. The Company provides systems
development, integration, engineering and network design, implementation and
security expertise services (its "Systems Business"). The Company also resells
computer hardware, software and integrated systems (its "Product Reselling
Business"). Through acquisitions, internal growth and successful contract
awards, the Company has increased its participation as a significant provider of
information technology solutions to the Government. The Company intends to
continue to expand and diversify its Government client base and to pursue other
opportunities for commercial application of its expertise. For fiscal 1996 and
the six months ended September 30, 1996, the Company's revenues were $213.6
million and $190.6 million, respectively, and its net income was $3.0 million
and $2.8 million, respectively. The Company's headquarters and executive offices
are located at 1945 Old Gallows Road, Vienna, Virginia 22182, and its telephone
number is (703) 556-6518.
 
INDUSTRY BACKGROUND
 
     Since the mid- to late 1980s, the Government, like many corporate
organizations, has increasingly adopted computer networking technology to
interconnect personal computers into resource-sharing work groups referred to as
local area networks. In recent years, there has been an increasing demand in the
information technology industry for open systems approaches designed to create
interoperability among COTS computer software and hardware products manufactured
by different suppliers. In addition, concerns over excessive development costs
and the rapid pace of technological change have led both Government and
commercial clients to demand flexible systems created by adapting
readily-available COTS software and hardware, rather than systems that have been
built to customized specifications.
 
     According to Federal Sources, Inc., an independent market research firm
specializing in the federal market, the United States Government is the world's
largest single buyer of information technology services and products. Federal
Sources estimates that Government spending was $26.3 billion ($9.8 billion by
DoD and $16.4 billion by civilian agencies) in the Government's fiscal 1996
(which ends September 30) and will be $26.5 billion ($9.7 billion by DoD and
$16.8 billion by civilian agencies) in its fiscal 1997. In addition, according
to the Electronic Industries Association, Government agencies that are not
required to report their information technology expenditures, including the
intelligence community, will spend an additional $20 billion in the Government's
fiscal 1997 on such technology. In the Government's fiscal 1997, total
Government spending is forecast to be approximately $46 billion.
 
     Since the late 1980s, the Government has made use of fewer, but
larger-scale, procurements to meet its information technology requirements,
requiring companies to have greater financial and technical resources in order
to participate in competitive bids. This has necessitated increased use of
teaming agreements among several firms in order to fulfill the requirements of
the larger procurements, which have frequently been awarded as IDIQ, multiple
party contracts. Increasingly, such IDIQ awards have been made to more than one
team which has resulted in post-award competition for contract orders. See
"-- Government Contracts -- Negotiated Procurement Contracts."
 
     The 1990s marked the emergence of rapidly developing Internet/intranet
technologies. Although information technologies, such as ARPANET, secure data
transmissions, and data encryption have long been in use in the military
intelligence arena, recent technological advancements in computer hardware and
software technology have now made such applications economically viable for use
by private companies. This has given rise to the need for specialized expertise
in the areas of local and wide area network design and installation, network
management and operation, and network security using complex, leading edge
information technology hardware and software products.

STRATEGY
 
     The Company's objective is to provide responsive and high-quality products,
services and solutions that meet the complete information technology needs of a
growing and increasingly diversified client base. The Company's strategies to
meet this objective are the following:
 
     Leverage Complementary Businesses.  The Company will continue to leverage
the core competencies of its Systems Business, including its expertise in the
areas of information warfare, intelligence systems, cost modelling and
simulation and local and wide area network design, implementation and
management, with the procurement capabilities of its Product Reselling Business
to provide complete information technology solutions. It draws on the resources
of these complementary businesses to bid on larger and more complex
procurements, either as prime contractor or as a sub-contractor, that will
generate increased revenue. In November 1995, for example, the Company was
selected as the prime contractor of a team comprised of BTG, EDS Corp. ("EDS")
and Sterling Software Inc. ("Sterling") to provide the United States Air Force
("USAF") and other members of the defense intelligence community with a full
range of integrated hardware and software products and services. Also, the
Company is applying its expertise in systems integration and networking
technology to develop revenue-generating opportunities in all areas of its
business.
 
     Pursue Strategic Acquisitions.  The Company will seek additional
opportunities to acquire companies with complementary technical capabilities,
new geographic locations, or clients in new markets. During the last four years,
the Company has made four such acquisitions. The recent acquisition of CAI, for
example, extended the Company's systems integration capabilities, particularly
in the civilian agency sector of the Government market. In addition, the Company
will seek to capitalize on cross-referral and cross-selling opportunities, as
well as economies of scale and reductions of overhead, that are provided by
acquisitions. The Company believes that continued consolidation within the
information technology industry will provide further opportunities to expand
through acquisitions.
 
     Use Teaming Relationships.  The Company is building teaming relationships
with other participants in the information technology industry that will enhance
its ability to participate in increasingly large and complex procurement
programs. The Company participates in such projects with major contractors,
including BDM International, Inc. ("BDM"), Coopers & Lybrand L.L.P. ("Coopers &
Lybrand"), EDS, International Business Machines Corp. ("IBM"), Sterling, UNISYS
Corporation ("UNISYS") and Xerox Corp. ("Xerox"). The IC4I contract was awarded
to a team comprised of BTG, EDS and Sterling. Two other teams were also
selected. The ITOP contract was awarded to a team led by BTG with Coopers &
Lybrand and eight other subcontractors, and eight other teams. The Company seeks
to use its teaming relationships to generate increased revenue and
profitability.
 
     Diversify Systems Business Towards Non-Defense Clients.  The Company will
seek to extend its expertise in systems integration and networking beyond its
traditional defense intelligence client base. Since the early 1980's, the
Company has provided systems design, integration, and engineering services and
computer hardware and software products to a variety of defense and intelligence
agencies. BTG has been involved in the development and continuing enhancement of
a number of networked systems designed to gather, analyze and distribute
sensitive intelligence information. This depth of expertise is directly
applicable to the emerging Internet/intranet and electronic commerce needs of
the civilian government and the commercial marketplace. The Company will use its
capabilities in open systems development, networking and network security,
client-server architecture, document imaging and information management,
together with its access to COTS hardware/software products, to expand its
growing civilian government and commercial business bases. In August 1996, for
instance, the Company was selected by the NIH as a prime contractor for
ImageWorld, a $100 million program for imaging systems, services and products.
The Company's team members include IBM and Xerox. Six other large contractor
teams and 13 small and minority businesses were also selected. Moreover, in
October 1996, the Company's contract with the Tennessee Valley Authority ("TVA")
to design and implement an accelerated delivery program to manage TVA's
inventory was extended for up to three years with a potential contract capacity
of more than $30 million.
 
     Leverage Expertise with Leading Edge Technologies.  The Company will
leverage its expertise with leading edge technologies to provide creative
solutions for complex systems integration and networking
 
                                       26

requirements. The Company is skilled in large scale document imaging,
information management and data retrieval and has developed a proprietary
document search system (TeraSEARCH) which is used by the Company in combination
with other COTS document management products (such as Excalibur's
RetrievalWare(TM) integrated with Netscape's Internet server). In addition, the
Company will continue to develop Internet/intranet applications using
sophisticated network security and encryption technology in tandem with leading
edge system vulnerability assessment and intrusion detection products like
WheelGroup's NetRanger(TM). The Company intends to continue to develop strategic
supplier alliances, such as those it has entered into with Netscape
Communications Corp., Excalibur Technologies Corporation, Verity Inc. and
WheelGroup, to ensure that the Company can provide the most complete, current
and innovative information technology products and services to its clients. The
Company will also continue to assemble custom, high-performance microcomputers
and servers with a variety of microprocessors, memory configurations and other
customized features.
 
COMPANY OPERATIONS
 
     The Company has organized its business into two principal areas: the
Systems Business and the Product Reselling Business. The Systems Business
accounted for 29.6%, 31.4% and 26.0% of total revenues in fiscal 1995 and 1996,
and the six months ended September 30, 1996, respectively, while the Product
Reselling Business accounted for 70.4%, 68.6% and 74.0% of total revenues during
such periods.
 
  THE SYSTEMS BUSINESS
 
     At the beginning of fiscal 1997, the Company organized the Systems Business
into two strategic units: the Systems Engineering Business Unit and the
Integration and Network Systems Business Unit. The Systems Engineering Business
Unit is generally engaged in system development, integration and engineering
activities primarily for defense oriented applications. The Integration and
Network Systems Business Unit is generally engaged in network development,
document imaging and electronic data interchange activities primarily for
non-defense oriented applications.
 
     Systems Engineering Business Unit.  The Company designs, develops and
integrates command, control, communications and intelligence systems that
provide open, modular computer-based solutions for specific military
applications, including information warfare. The Company provides competitive
and rapidly accessible solutions to its clients using either COTS software and
hardware from multiple providers or custom-built systems.
 
     The Company has expertise in data assimilation and correlation
applications, that is, the technique of accepting, analyzing and displaying
electronic data from land-, sea-, air-, and space-based sensors, so it can be
rapidly evaluated. The Company's systems give a coherent picture of the
available electronic information, as well as the means to share such
information. The Company has developed both tactical systems, which allow users
to act upon intelligence data immediately, and analytical systems, which permit
use of data for evaluation and planning purposes. These types of systems have
been used in a variety of military settings, including operations in the Middle
East, Somalia, Bosnia and Korea, for tracking troop movements and other
intelligence functions.
 
     The Company uses its expertise to build fully-integrated systems for
military intelligence applications. These systems contain state-of-the-art
software and hardware products and are often "ruggedized" for use in harsh
climates or hazardous environments. The Company uses its integration expertise
to help clients achieve interoperability and integration of multiple information
systems and to permit the sharing of information across dissimilar systems,
thereby increasing the speed and efficiency with which information retrieval and
processing can occur. The Company furnishes a variety of services, such as
requirements analysis, hardware and software selection, hardware and software
on-site installation, systems packaging, troubleshooting, maintenance, repair,
and user training, to accomplish the integration and continuing support of its
systems. The Company is also involved in the DoD information warfare initiative
designed to protect sensitive information resident in a variety of military
intelligence networks and systems. In this regard, the Company is the exclusive
provider to the Government of WheelGroup's NetRanger(TM) products which provide
the client with network vulnerability and intrusion detection capabilities.
 
                                       27
<PAGE>   29
 
     The Company provides engineering and technical support to its clients
across a wide array of technical disciplines, including systems design, planning
operations and maintenance, configuration management, logistics, training and
cost control. The Company's engineering functions generally focus on client
needs for configuration management, re-engineering of existing systems,
maintenance and technical support. The Company performs software engineering to
develop and prototype various data processing and correlation algorithms,
systems engineering to integrate complex network and mainframe systems, and
management engineering to coordinate and control large system operations,
implementation and upgrades.
 
     The following are significant Systems Engineering Business Unit contracts
and programs:
 
     - The IC4I contract, which was awarded in November 1995 to a team comprised
       of BTG, EDS, and Sterling with BTG as the prime contractor and EDS and
       Sterling as sub-contractors, requires the BTG team to provide the USAF
       and other members of the defense intelligence community with a full range
       of integrated hardware and software products and services. Two other
       teams were also selected. The IC4I program will focus primarily on the
       manufacture and development of interoperable systems and subsystems to
       upgrade the defense intelligence system. The IC4I contract is a five-year
       program with total contract capacity of approximately $929 million.
       Although there can be no assurances, the Company believes that the
       potential value to BTG under this contract is in excess of $300 million.
       The IC4I program began generating revenues in fiscal 1997. During the six
       months ended September 30, 1996, $7.9 million of revenue was recognized
       by the Company under this contract.
 
     - The U.S. Department of Transportation's Information Technology Omnibus
       Procurement Program ("ITOP") program, which was awarded in May 1996 to a
       team comprised of BTG as the prime contractor, Coopers & Lybrand and
       eight other subcontractors, will focus on providing systems engineering
       services in the areas of electronic commerce and electronic data
       interchange, Internet access and intranet support, local and wide area
       networks, software engineering, office automation support, and business
       process reengineering. Eight other teams were also selected. The ITOP
       contract is a seven-year program with a total contract capacity of
       approximately $1.1 billion. Although there can be no assurances, the
       Company believes that the potential value to BTG under this contract is
       approximately $50 million.
 
     Integration and Network Systems Business Unit.  The Integration and Network
Systems Business Unit focuses on the adaptation of the Systems Business
expertise to non-defense oriented applications and seeks to leverage the Systems
Business expertise with the procurement capabilities of the Product Reselling
Business.
 
     The Company uses its specialized expertise in the areas of local and wide
area network design and installation, network management and operations, and
network security to develop custom networks and Websites. For example, the
Company (i) helped develop customized Websites for Strong Capital Management
Inc., Spencer Gifts, Inc., the Fairfax County Economic Development Authority and
the U.S. Conference of Mayors, (ii) formed a new subsidiary corporation, CNI, to
work with established cable operators to provide local communities with a range
of Internet/intranet services and (iii) has designed, installed, secured, and/or
managed a variety of networks for its clients.
 
     The Company uses its expertise in document imaging and data retrieval and
organization to provide innovative document storage and retrieval services. BTG
used its proprietary TeraSEARCH imaging system in support of a major defense
client. The system was installed and the first thousand pages indexed in one
day. The system gave researchers and lawyers rapid search and retrieval access
to information that would otherwise be buried in millions of pages of notes,
contracts, and engineering reports. Initially sized for two million document
pages, the system was upgraded to handle over seven million pages. Document
capture and search features were enhanced to work with bate stamps (unique
document identifiers used in the legal profession), and the system has been
integrated with relational database technology to track specific document
information like dates and witnesses.
 
     BTG combines its networking and computer integration skills to create
Electronic Data Interchanges ("EDI"s) to help its clients implement inventory
programs. For example, BTG designed and implemented an accelerated delivery
program for the TVA using an EDI to ensure that the TVA could obtain key
computer
 
                                       28

products within five days of ordering. The Company set up a similar system
specifically tailored to satisfy Freddie Mac's unique purchasing preferences,
including same-day delivery.
 
     The following are significant Integration and Network System Business Unit
contracts and programs:
 
     - In August 1996, NIH awarded its ImageWorld program to a team comprised of
       BTG, IBM, Information Management Consultants, Inc., I-NET Inc., Sensor
       Systems, Inc. and Xerox. Six other large contractor teams and 13 small
       and minority businesses were also selected. The teams will compete for
       task orders for imaging technology, document conversion and electronic
       storage, and electronic document management. The goal is to convert
       traditional paper databases into electronic files that can be retrieved
       and shared among Government workers. The NIH program is a five-year
       program with a total contract capacity of $100 million. Although there
       can be no assurances, the Company believes that the potential value to
       BTG under this contract is approximately $10 million.
 
     - Since September 1994, the Company, and its wholly-owned subsidiary CAI,
       have provided to the Department of Education ("DoE") roughly 100
       automation support professionals from all technical specialties and a
       variety of networking and integration services under a large facilities
       and engineering support contract. Recently, the Company installed and
       customized a complex WorldWide Web server that will enable the DoE to
       publish grant announcements and procurement information on the Internet.
       The DoE contract is a five-year program, including option periods, with a
       total contract capacity of $60 million. Although there can be no
       assurances, the Company believes the potential value to BTG under this
       contract is approximately $50 million. Revenues in fiscal 1996 and the
       six months ended September 30, 1996 were $4.3 million and $6.6 million,
       respectively. The DoE contract has accounted for approximately $17.2
       million in total revenues through September 30, 1996.
 
  THE PRODUCT RESELLING BUSINESS
 
     Technology Systems Business Unit.  As a product reseller of computer
hardware, software and integrated systems, the Company, through its Technology
Systems Business Unit, provides clients with advanced technology products in the
areas of enterprise networking, the UNIX operating system environment, data
storage, image processing and high-performance client/servers. The Company
emphasizes open architecture and widely accepted industry standards in
identifying specific products to be used in clients' systems. The Company sells
directly to the Government and to systems integrators and prime contractors
selling to the Government market.
 
     A significant percentage of the Company's revenues (41.3% in fiscal 1996
and 54.5% during the six months ended September 30, 1996) is derived from
product sales to the Government under a variety of agency-specific IDIQ
contracts. For example, the Company provides microcomputer systems, servers,
networking components, software and services under its TDA-2 contract to the
Department of the Treasury; microcomputer systems, UNIX systems, networking
components, software and services under its contract with the NIH; COTS
software, including Applixware Word, Spreadsheet, and Send Mail, Oracle 7 Office
Relational Database Management System and Interleaf WorldView Press under its
SASS contract with the Defense Intelligence Agency ("DIA"); and portable PCs,
office automation software, computer peripherals, and technical support and
warranty maintenance under its NTOPS contract with the Department of the Navy.
More recently, the Company and one other government contractor was awarded the
U.S. Army's PC-2 contract to supply the Army with high performance COTS hardware
and software. The contract has a total contract capacity of $554 million over
two years. Although there can be no assurances, the Company believes the
potential value to BTG is approximately $200 million.
 
     Another significant percentage of the Company's revenues (19.4% in fiscal
1996 and 11.8% for the six months ended September 30, 1996) is derived from
sales to the Government either directly under the Company's four GSA Schedule
contracts or from sales to other prime contractors with GSA Schedule contracts.
See "-- Government Contracts -- The GSA Schedules." GSA Schedule contracts
permit the Company to offer over 50,000 products from more than 300 suppliers.
Representative products include operating systems, work stations, file servers,
backup and storage systems, printers, secure wide area networks, hardware
peripherals, computer software, and document imaging software.
 
                                       29

     In order to complement its ability to provide complete solutions to its
clients, the Company's Product Reselling Business assembles and sells a line of
high-performance RISC- and Intel-based computers under its own BTG trade name.
BTG has an agreement with Digital under which Digital supplies it with Alpha
microprocessors. The BTG systems offer Microsoft's Windows and Windows NT
operating systems, with access to thousands of COTS software applications. The
Company offers a full range of support services to clients purchasing BTG
systems, including testing, installation, maintenance and user support.
Approximately 4.2% of total revenues in fiscal 1996 and for the six months ended
September 30, 1996, were obtained from sales of products carrying the BTG trade
name.
 
     The Company has invested in infrastructure improvements over the past two
years to support its product reselling activities, including automated order
processing, inventory control and status checking systems that permit 48-hour
turnaround on most orders. The Company provides its clients a range of support
services, including employee training, maintenance, repair and user assistance.
Products sold by the Company are protected by a variety of warranties, and the
Company also offers extended service contracts for many products. Technical
support services are often provided by personnel in the Company's systems
development, integration and engineering business areas, although third-party
service firms are also used in certain instances. In order to provide a
centralized source of products for its clients, the Company maintains strong
relationships with leading providers of hardware and software products. See
"-- Suppliers."
 
CLIENTS
 
     The Company derives a substantial portion of its revenues from contracts
with various agencies of the Government, including all four armed forces, the
DIA, the GSA, the National Security Agency ("NSA"), and many of the civilian
Government agencies such as the Environmental Protection Agency, and the
Departments of Treasury and Education. Under the NATO BOA, the Company has sold
services and products to member countries and agencies of NATO. In addition, the
Company has performed projects for, or supplied computer hardware, software and
integrated systems to, a limited number of commercial clients, as well as
several state and local governments. As of September 30, 1996, the Company was
performing on over 90 active Government contracts, with a total contract
capacity (including option periods) in excess of $1.0 billion. This amount was
increased to over $1.3 billion as a result of the award of the U.S. Army's PC-2
contract to the Company in October 1996. See "-- Backlog."
 
     In fiscal 1995, 1996 and the six months ended September 30, 1996, the
Company derived approximately 91.2%, 89.8% and 89.6%, respectively, of total
revenues from Government contracts. The following table sets forth the Company's
estimates of its total revenues in the last two fiscal years and for the six
months ended September 30, 1996:

TEAMING RELATIONSHIPS
 
     The Company maintains teaming relationships with major Government
contractors, including BDM, Coopers & Lybrand, EDS, Sterling, UNISYS and Xerox,
in order to bid on and participate in a greater number of increasingly large and
complex procurement projects. Teaming relationships have enabled BTG to secure
several large Government contracts such as the IC4I contract, which was awarded
in November 1995 to a team comprised of BTG, as the prime contractor, EDS and
Sterling. The IC4I contract requires the BTG team to provide the USAF and other
members of the defense intelligence community with a full range of integrated
hardware and software products and services.
 
SALES AND MARKETING
 
     Within its Systems Business, the Company's sales and marketing activities
are conducted by senior management and its own professional staff of engineers,
analysts and other personnel. Within its Product Reselling Business, the Company
employs approximately 86 sales and marketing personnel, of whom 79 are primarily
engaged in sales and seven are primarily engaged in marketing activities. The
Company provides training to its sales force on various Government procurement
processes and technical features of the products and services it offers. All
sales personnel have been trained on, and have on-line access to, the Company's
computerized system for maintaining price, product availability, bid, ordering
and order-status information. Marketing personnel design and direct the
Company's market research, telemarketing and direct mail campaigns, and oversee
product management efforts. The Company also plans to implement Company-
sponsored catalogues and seminars, advertise in specialty trade publications and
participate in major trade shows.
 
BACKLOG
 
     Many of the Company's Government contracts, while extending for more than
one year, are funded by the procuring agency on an annual basis. This results in
a variance between "funded backlog" and "contract backlog." In addition, many of
these contracts contain a total contract capacity reflecting the maximum amount
that the Government can purchase under the contract. Contract backlog is a
portion of total contract capacity and represents management's estimate of the
aggregate contract revenues that will be earned by the Company over the life of
the contract, including option periods. Funded backlog represents the extent to
which Government contracts have been funded by procuring agencies. Funded
backlog generally varies over the course of a year depending upon procurement
and funding cycles. As a result, year-to-year comparisons are difficult and not
necessarily indicative of any future trends in revenues.
 
     The Company's estimated contract backlog as of March 31, 1995 and 1996 and
September 30, 1996 was $227.7 million, $788.0 million, and $857.0 million,
respectively. Of these amounts, the Company estimates that $34.1 million, $36.0
million and $104.7 million, respectively, represented funded backlog. Moreover,
the U.S. Army's PC-2 contract awarded in October 1996 increased the Company's
contract backlog by $200 million to over $1.0 billion. The Company believes that
the increase in estimated contract backlog as compared with funded backlog over
these periods is a reflection of the Government's increased reliance upon IDIQ
contracts. See "-- Government Contracts -- Negotiated Procurement Contracts."
Due to the Government's ability to select multiple winners under its IDIQ
contracts, as well as its right to limit orders to any particular awardee, there
can be no assurances that unfunded contract backlog will result in actual
orders.
 
SUPPLIERS
 
     The Company devotes significant resources to establishing and maintaining
relationships with its suppliers. The Company offers its suppliers a number of
opportunities to expand their sales to the Government market, including access
to the Government market through numerous diverse contracts, relief from
compliance costs of procurement regulations for selling directly to the
Government market, lower costs for selling and marketing programs, and
elimination of billing and collection costs related to the Government market,
and participation in product services, including numerous Government-specific
marketing programs and end-user technical support.
 
                                       31
<PAGE>   33
 
     The terms of the Company's agreements with its suppliers vary widely, but
typically permit the Company to purchase products for resale to the Government.
Most of the Company's supplier agreements do not require the Company to purchase
any specified quantities of product. The Company typically requires suppliers
acting under its Government contracts to provide the Company with supply and
price protection for the duration of such contracts. Other than supplier
agreements under Government contracts, the Company's supplier agreements are
typically terminable by the supplier on short notice, at will or immediately
upon default by the Company. These supplier agreements also typically permit the
Company to return previous product purchases at no charge, for a specified
restocking fee and/or in exchange for other products of the supplier. The
Company also purchases some products from independent distributors.
 
     Suppliers provide the Company with incentives in the form of discounts,
rebates, credits, inventory financing programs and cooperative advertising and
market development funds. In accordance with the terms of its Government
contracts, the Company provides periodic reporting of pertinent supplier
contract terms and conditions to Government contracting officials. A reduction
in or discontinuance of these incentives or significant delays in receiving
reimbursements could materially adversely affect the Company.
 
     As a product reseller, the Company must continue to obtain products at
competitive prices from leading suppliers in order to provide a centralized
source of price-competitive products for its clients and to be awarded new
Government contracts and Government orders under its existing IDIQ contracts.
Although most of the Company's suppliers currently do not sell their products
under their own GSA Schedule contracts, certain suppliers have, and others may
apply for, their own GSA Schedule contracts and may sell their products at lower
end-user prices than those the Company currently offers or could profitably
offer. Although the Company believes its relationships with its key suppliers to
be good, certain actions by suppliers could adversely affect the Company's
operations, including sales directly to the Government, sales to the Company's
competitors on more favorable terms than to the Company, use of additional
resellers to represent their products on a GSA Schedule contract, restriction or
termination of the Company's rights to sell their products, or restriction of
their products from being carried on a GSA Schedule contract.
 
GOVERNMENT CONTRACTS
 
     Approximately 91.2%, 89.8% and 89.6% of the Company's total revenues in
fiscal 1995, 1996 and for the six months ended September 30, 1996, respectively,
were derived from business performed under the following two types of Government
contracts (i) contracts obtained through a negotiated procurement process and
(ii) GSA Schedule contracts. The Company's activities within its Systems
Business are generally performed under contracts obtained through negotiated
procurements, while the Company's product reselling activities are generally
performed under both negotiated procurement contracts (IDIQ type) and GSA
Schedule contracts.
 
     Government contracts are generally subject to a number of risks including,
for example, the termination of contracts by the Government for convenience or
default, the availability of Government funding, the right of the Government not
to exercise option years under contracts, to amend contracts and to subject
contracts to a competitive rebidding process, the adjustment of costs and
revenue by Government auditors, and the shutdown or partial shutdown of selected
Government agencies. Prior to fiscal 1996, the Company had not been materially
affected by the foregoing risks. In the latter half of fiscal 1996, however, the
Company's operations were adversely affected by the Government's budget impasse
which resulted in the partial shutdown of the Government for several weeks
during the third and fourth quarters of the Company's fiscal year. This partial
shutdown had a negative impact on the Company's third quarter operations. In
addition, the processing of payments under Government contracts was delayed by
the shutdowns. This resulted in the Company having to carry its outstanding
receivable accounts for longer periods of time which, in turn, meant higher
interest costs. The potential exists for similar Government shutdowns in future
years. The extent of any impact on the Company's results of operations,
financial position, or liquidity resulting from possible future shutdowns cannot
be predicted at this time.
 
     Negotiated Procurement Contracts.  Negotiated procurement contracts include
cost-reimbursement contracts (both cost-plus-fixed-fee and cost-plus-award-fee),
time and materials contracts, fixed-price
 
                                       32

contracts and IDIQ contracts. Revenues derived under negotiated procurement
contracts during fiscal 1995 and 1996 and the six months ended September 30,
1996 were as follows by contract type:

* Approximately $9.2 million, $9.6 million and $14.1 million of total Company
  revenues in fiscal 1995 and 1996 and the six months ended September 30, 1996,
  respectively, were generated under IDIQ contracts which were primarily
  service-oriented. Approximately $69.3 million, $88.1 million and $103.9
  million of total Company revenues in fiscal 1995 and 1996 and the six months
  ended September 30, 1996, respectively, were generated under IDIQ contracts
  which were primarily product-oriented.
 
     Cost-plus-fixed-fee contracts provide for the reimbursement of incurred
costs during contract performance, to the extent that such costs are allowable
and allocable, and the payment of a fixed fee. The size of such fees as a
proportion of the contract value is limited by law. Cost-plus-award-fee
contracts typically provide for the reimbursement of costs with a base fee and
an additional fee that is based upon a periodic evaluation of the contractor's
performance against specified criteria. Under time and materials contracts, the
contractor agrees to provide certain categories of labor that satisfy
established education and experience qualifications at a fixed hourly rate. To
the extent a contractor's costs differ from the fixed hourly rate, the
contractor realizes all of the benefit or detriment resulting from decreases or
increases in the cost of performing the work. Under fixed-price contracts, the
contractor agrees to perform certain work for a fixed price and, accordingly,
realizes all the benefit or detriment resulting from decreases or increases in
the cost of performing the work.
 
     Under typical IDIQ contracts, the contractor agrees to provide specific
products and related services at specified unit prices. These contracts, which
are often awarded for large scale Government purchases of computer hardware,
software and integrated systems, are typically awarded through a formal
competitive bid process. The periods of performance for IDIQ contracts typically
span a base year and a number of option years. Under IDIQ contracts, the
Government is under no obligation to make purchases at levels approved under the
contract. As part of the Government mandate to stream-line procurement
contracting procedures, agencies are awarding IDIQ contracts to multiple
parties. Each winner then has an opportunity to provide the types of products
and services described in the contract. The agency then typically buys from the
most competitive contractor without going through additional formal procurement
procedures. IDIQ contracts are often subject to modification as products
included in original contract specifications are replaced with new technology.
 
     Unsuccessful offerors on bids for negotiated procurement contracts often
bring protests challenging agency action in connection with the procurement,
either before the General Accounting Office (the "GAO"), the United States Court
of Federal Claims, a United States District Court or another appropriate forum.
The Company is currently aware of a bid protest of its U.S. Army's PC-2
contract. Although there can be no assurances, management believes that the
award of the U.S. Army's PC-2 contract to the Company will be upheld.
 
     The GSA Schedules.  Approximately 19.4% and 11.8% of the Company's total
revenue in fiscal 1996 and the six months ended September 30, 1996,
respectively, were derived from sales pursuant to GSA Schedule contracts held by
the Company during those periods and from sales to other prime contractors of
the Government with GSA Schedule contracts. The Company is one of the 10 largest
GSA Schedule holders and holds four GSA Schedule contracts: one Schedule A
contract for turnkey and large systems products; one Schedule B/C contract for
microcomputers, software and peripheral equipment; one Schedule E contract for
 
                                       33
<PAGE>   35
 
electronic commerce, electronic data interchange, automated procurement systems
and BTG services; and one Schedule 58VA for miscellaneous supplies related to
sales pursuant to the Company's other GSA Schedules. The Company's GSA Schedules
have terms ranging from one to five years. The Company has not experienced any
difficulty in obtaining renewal of its GSA Schedule contracts.
 
     At the time of initial award, prices to the end-users under the Company's
GSA Schedules are set for the duration of the contract at a specified level or
at specified levels varying over time. In addition, under certain circumstances,
BTG is required under the terms of its GSA Schedules to pass on any savings,
resulting from supplier discounts, or other price reductions, to the Government
in the form of corresponding price reductions. Furthermore, the GSA Schedules do
not have pre-set delivery schedules or minimum purchase levels. The
uncertainties related to future contract performance costs, quantities to be
shipped and dates of delivery make it difficult to predict the future revenues
and profits, if any, that may result from such contracts.
 
     The Procurement Process.  The Company's Government Contracts Department,
which consisted of 11 employees at September 30, 1996, prepares bids on
procurements and advises Company personnel on a wide variety of technical and
practical issues relating to the procurement process. The Company believes its
experience in the procurement process enables it to identify procurement
opportunities and to manage resources cost-effectively in the pursuit of a
variety of procurement bids. It is involved in evaluating bid opportunities,
identifying key products or services needed to respond to bids, negotiating
favorable agreements with suppliers and co-contractors, preparing written
responses to the solicitation document, meeting all mandatory technical
requirements and, in general, successfully processing the proposal effort from
initial submission to post-award implementation. This department also monitors
compliance with the relevant procurement regulations and keeps abreast of
changes in such regulations.
 
COMPETITION
 
     In seeking to provide a broad range of services and products that address
the complete information technology needs of its clients, the Company
participates, to varying degrees, in multiple segments of the information
technology market, including markets for systems engineering, development and
integration and networking and document imaging services and for the sale of
products and component parts. Each of the market segments in which the Company
operates is competitive. Within each segment, the Company competes against
different firms of varying sizes, with different specializations and skills. The
number and size of competitors vary among operating groups and within the
individual divisions of each group. Frequently, the number and identity of
competitors vary even from program to program within a given business area. Many
of the Company's competitors are significantly larger and have greater financial
resources than the Company. Some of these competitors are divisions or
subsidiaries of large, diversified companies that have access to the financial
resources of their parent companies. In the Product Reselling Business, the
Company competes with certain computer manufacturers, who sell directly to the
Government market, as well as a number of systems integrators, resellers and
distributors. In addition, the Company is always at risk to potential
competition from its suppliers in its Product Reselling Business. See
"-- Suppliers."
 
     The Company believes that the principal competitive factors in the Systems
Business are technical understanding, management capability, past contract
performance, personnel qualifications and price. In the Product Reselling
Business, the Company believes that while price is still the most important
competitive factor, the Government has recently placed greater emphasis on a
company's past performance. During its recent history, the Company has been
successful in winning new and repeat contract awards in its Product Reselling
Business and in the exercise of contract option years in its Systems Business,
both of which the Company believes are attributable to the strength of its past
contract performance and its competitive prices. Further, the Company's senior
management team has an extensive number of years of industry specific technical
and managerial experience. As a result, the Company believes that it competes
favorably on each of the principal competitive factors within both its Systems
and Product Reselling Businesses.

CERTAIN REGULATORY MATTERS
 
     The nature of the Company's business subjects the Company to various
regulatory restrictions and limitations, including those set forth below.
 
     Security Clearances.  Many of the Company's Government contracts require
the Company to maintain facility security clearances complying with DoD
requirements. The Company believes that it is in compliance with these
requirements. As of September 30, 1996, approximately 37% of the Company's
employees possessed secret or top secret security clearances, which are required
for the performance of certain of the Company's contracts. The Company has never
had a contract terminated for security reasons.
 
     Government Contract Audits and Investigations.  Government contractors are
commonly subject to various audits and investigations by Government agencies.
Among the agencies that oversee or enforce contract performance are the DCAA,
the Inspectors General of the various departments, the Defense Criminal
Investigative Service, the GAO and the Department of Justice. These audits and
investigations involve a review of a contractor's performance on its contracts,
as well as its pricing practices, costs and compliance with applicable laws,
regulations and standards. The DCAA generally audits cost-reimbursable contracts
to verify that costs have been properly charged to the Government. Final audits
by the DCAA have been completed for the Company's fiscal years through 1992. The
Company has not experienced any material adverse effects as a result of these
completed audits. The DCAA is currently in the process of completing its audits
for the Company's fiscal years 1993 and 1994. Management does not expect the
completion of these audits, or of future audits on open years 1995 and 1996, to
have a material adverse effect on the Company's consolidated financial position.
 
     One of the Company's contracts was audited during fiscal year 1996 by the
Inspector General of the Government agency. The Company was recently notified
that the Government was seeking to recover approximately $156,000 as a result of
the audit. The Company does not believe this audit will have a material adverse
effect on the Company.
 
EMPLOYEES
 
     As of September 30, 1996, the Company employed 1,021 employees, 725 of whom
were technical/managerial staff, 210 of whom were administrative staff and 86 of
whom were engaged in sales and marketing. As of such date, 378, or 37%, of the
Company's employees possessed secret or top secret security clearances, which
are required for the performance of certain of the Company's contracts. The
Company believes that it is competitive in hiring and retaining qualified
personnel. The Company's ability to remain competitive will be based in large
measure upon its ability to recruit and train qualified personnel. None of the
Company's employees is represented by a labor union. The Company considers its
relations with its employees to be good and has not experienced any significant
labor problems.

     The Company leases all of the offices and facilities used in connection
with its operations, which as of September 30, 1996 comprise approximately

expenses) per committee meeting attended. Attendance via telephone is
compensated at one-half of the normal rate. Directors also receive options under
the Directors Stock Option Plan (the "Directors Plan"). The Directors Plan
provides for the granting of a maximum of 100,000 non-qualified stock options to
non-employee members of the Board of Directors. The option price per share is
equal to the fair market value of a company share on the date of grant. The term
of each option is 10 years, and an option first becomes exercisable six months
after the date of grant. Under the terms of the Directors Plan, each
non-employee member of the Board of Directors will be granted 1,000 options on
each anniversary date of the director's service commencement date. During fiscal
1996, 10,000 options, with a per share exercise price of $11.25, were granted
under the Directors Plan. In addition, on October 15, 1996, the Board adopted
the BTG Non-Employee Director Stock Purchase Plan pursuant to which non-employee
directors may elect to have their fees invested in BTG common stock at 100% of
the fair market value ("FMV"). FMV is based upon the lower of the closing price
for the stock at the beginning or end of an election period. The election period
is the 12-month period beginning October 1 of each year. Up to 100,000 shares
can be issued under the plan. The plan is subject to shareholder approval.

 (1) The information as to beneficial ownership is based on statements furnished
     to the Company by the beneficial owners. Under the rules of the Securities
     and Exchange Commission, "beneficial ownership" means the sole or shared
     power to vote or direct the voting of a security, or the sole or shared
     investment power with respect to a security (i.e., the power to dispose, or
     direct the disposition, of a security). A person is deemed as of any date
     to have "beneficial ownership" of any security that such person has the
     right to acquire within 60 days after such date. More than one person may
     be deemed to be a beneficial owner of the same securities. Each of the
     shareholders listed on the table has agreed not to sell or otherwise
     dispose of the shares to be beneficially owned by them after the offering
     for a period of 120 days after the date of this Prospectus. See "Shares

                          DESCRIPTION OF CAPITAL STOCK
 
     The following description is based, in part, on BTG's Amended and Restated
Articles of Incorporation (the "Amended Articles"). The authorized capital stock
of BTG consists of 10,000,000 shares of BTG Common Stock, of which 6,173,782
were outstanding as of September 30, 1996, and 1,000,000 shares of Preferred
Stock, none of which are outstanding.
 
COMMON STOCK
 
     Each share of Common Stock is entitled to one vote. Shareholders do not
have cumulative voting rights in the election of directors. In the event of a
liquidation, dissolution, or winding up of BTG, the holders of Common Stock are
entitled to share ratably in all assets remaining after payment of liabilities,
subject to prior distribution rights of Preferred Stock, if any, then
outstanding. Subject to preferences that may be applicable to any outstanding
Preferred Stock, the holders of Common Stock are entitled to receive ratably
such dividends, if any, as may be declared from time to time by the Board of
Directors out of legally available funds. BTG does not currently intend to pay
cash dividends on its Common Stock. The Common Stock has no preemptive or
conversion rights or other subscription rights. There are no redemption or
sinking fund provisions available to the Common Stock. All outstanding shares of
Common Stock are fully paid and non-assessable, and the shares of Common Stock
to be issued upon completion of the offering will be fully paid and
non-assessable.
 
PREFERRED STOCK
 
     The Board of Directors may, without action by the shareholders of BTG,
issue Preferred Stock from time to time in one or more series for such
consideration and, within certain limits, with such relative rights, privileges
and preferences as the Board of Directors may determine. Accordingly, the Board
of Directors has the power to fix the dividend rate and to establish the
provisions, if any, relating to voting rights, redemption rate, sinking fund,
liquidation preferences and conversion rights for any series of Preferred Stock
issued in the future. Issuance of the Preferred Stock, while providing BTG
flexibility in connection with possible acquisitions and other corporate
purposes, may be used, in certain circumstances, to create voting impediments on
extraordinary corporate transactions or to frustrate persons seeking to effect a
merger or otherwise to gain control of BTG. BTG has no present plans to issue
any shares of Preferred Stock.
 
STOCK WARRANTS
 
     The Company issued and sold to Nomura warrants to purchase an aggregate of
317,478 shares of Common Stock pursuant to an agreement entered into between the
Company and Nomura on February 16, 1996. Under the Warrants, Nomura has the
right to purchase the covered shares for an exercise price of $9.50 per share at
any time before February 16, 2003.
 
LIMITATION OF LIABILITY
 
     BTG's Amended Articles limit the liability of its directors and officers to
the maximum extent permitted by Virginia law. Thus, the directors and officers
of BTG shall not be personally liable to BTG or its shareholders for any breach
of any duty based upon an act or omission, except for an act or omission (i)
resulting from such person's willful misconduct or (ii) in knowing violation of
criminal law.
 
VIRGINIA ANTI-TAKEOVER PROVISIONS
 
     The Virginia Affiliated Transactions statute imposes restrictions on
certain transactions between a public Virginia Corporation and a 10% beneficial
shareholder of the corporation (the "Interested Shareholder"). Under this
statute, significant transactions (such as a merger, a transfer to the
Interested Shareholder of corporate assets worth more than 5% of net worth, or a
reclassification of securities having the effect of increasing by 5% or more the
corporation's outstanding voting shares held by any Interested Shareholder)
between the corporation and an Interested Shareholder must receive the approval
of both a majority of disinterested directors and the holders of two-thirds of
the corporation's voting shares (not including the
 
                                       44
<PAGE>   46
 
Interested Shareholder's shares). After an Interested Shareholder has held the
stock for three years, the transaction may proceed upon the approval of either
the disinterested directors or the holders of two-thirds of the voting shares.
The corporation may avoid application of the statute if a majority of the
disinterested directors approves the initial 10% stock acquisition by the
Interested Shareholder. In addition, this statute does not apply to an
Interested Shareholder who has been such continuously since the date the
corporation first became a public corporation.
 
CERTAIN PROVISIONS OF BTG'S AMENDED AND RESTATED ARTICLES OF INCORPORATION
 
     BTG's Amended Articles provide for the Board of Directors to be divided
into three classes serving staggered terms. As a result, only one class of
directors will be elected at each annual meeting of the shareholders, and the
time required to elect a new majority to the Board of Directors will be
extended. The Amended Articles grant to the Board the authority to set from time
to time the size of the Board within a range between seven and 15 directors. The
shareholders can change the number of directors, either within or without the
range, only by a super-majority vote at a meeting called for such purpose. The
Amended Articles provide that only the Board of Directors may fill vacancies on
the Board. The Amended Articles further provide that the shareholders may remove
directors only for "cause" as defined in the Amended Articles, and only by
approval of a super-majority vote of the shareholders at a meeting called for
such purpose. Under the Amended Articles, a special meeting of shareholders may
only be called by (i) the Chairman of the Board, (ii) the President, (iii) the
Board of Directors, or (iv) holders of more than 50% of the shares (or of 20% of
the shares if no annual shareholders' meeting has been held within 15 months of
the last annual shareholders' meeting). The Amended Articles grant to the Board
of Directors the authority to consider an array of factors, including
non-economic factors, in deciding whether to approve an acquisition of BTG. In
addition, the Amended Articles permit the shareholders to amend the bylaws only
by a super-majority vote at a meeting called for such purpose. BTG's bylaws
contain certain restrictions on the rights of shareholders to put forth
shareholder proposals and nominate directors. The foregoing provisions of BTG's
Amended Articles and bylaws could have the effect of discouraging a third party
from attempting to obtain control of BTG, even though such attempt might be
beneficial to BTG and its shareholders, and could have a depressive effect on
the market price of the BTG Common Stock. BTG believes that such provisions will
help to assure the continuity and stability of BTG's Board of Directors and
BTG's business strategies and policies.
 
REGISTRATION RIGHTS
 
     The holders of the Warrants are entitled to certain rights with respect to
the registration under the Securities Act for resale to the public, of an
aggregate of 317,478 shares of (the "Registrable Securities"), pursuant to the
terms of the Nomura Agreement. The Nomura Agreement provides that, with certain
limited exceptions, if the Company proposes to register under the Securities Act
for its own account or for the account of the Selling Shareholder, such warrant
holders are entitled to include their Registrable Stock in any such
registration, subject to certain conditions and limitations. Subject to certain
limitations, the Company is required to bear the expenses of all such
registrations.
 
TRANSFER AGENT
 
     BTG's transfer agent is First Union National Bank of North Carolina.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion of the offering, the Company will have 7,843,782 shares of
Common Stock outstanding (8,186,282 shares if the Underwriters' over-allotment
options are exercised in full) 4,728,124 (including up to 24,933 shares issued
pursuant to the Company's Employee Stock Purchase Plan which are subject to a
six-month holding requirement) of which will be freely tradeable without
substantial restriction or the requirement of future registration under the
Securities Act except for shares held or purchased by "affiliates" of the
Company as that term is defined in Rule 144, and 1,766,806 shares will be
"restricted securities" under Rule 144. The outstanding restricted securities
which are not sold in this offering are either currently eligible for sale under
Rule 144, or will be eligible for sale under Rule 144 commencing 120 days from
the date of this Prospectus to the extent such restricted securities are held by
signatories to the lock-up agreements described below, subject in each case to
applicable volume and manner-of-sale limitations. Of the 6,173,782 shares of
Common Stock outstanding as of September 30, 1996, 2,966,902 shares are freely
tradeable, 1,766,806 shares (of which no shares are being offered hereby) are
restricted securities under Rule 144, and 1,415,081 additional shares (of which
80,000 shares are being offered hereby) are held by directors and executive
officers who may be deemed affiliates of the Company pursuant to Rule 144, and
which shares may be sold subject to the provisions of Rule 144 and the
contractual restrictions described below.
 
     The Company, the Selling Shareholder and the executive officers and
directors of the Company have agreed that they will not, 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 other capital stock of the Company
or any securities convertible into, or exercisable or exchangeable for, any
shares of Common Stock or other capital stock of the Company for a period of 120
days from the date of this Prospectus, without the prior written consent of
Prudential Securities Incorporated, on behalf of the Underwriters. There is an
exception under this agreement for the Company to grant additional options under
the Company's Directors Stock Option Plan and 1995 Employee Stock Option Plan
and to issue stock under the Annual Leave Stock Plan, Employee Stock Purchase
Plan and Non-Employee Director Stock Purchase Plan. Upon expiration of these
lock-up agreements, all 1,887,259 shares held by such executive officers,
directors and the Selling Shareholder which are not sold in this offering will
become eligible for sale in the public market, subject to the applicable volume
and manner-of-sale limitations of Rule 144, and 148,834 shares of Common Stock
issuable upon exercise of currently outstanding options will become eligible for
sale as such options become vested. In addition, 24,993 shares become freely
tradeable, pursuant to the terms of the Employee Stock Purchase Plan between
December 31, 1996 and April 1, 1997. Under Rule 144, the volume limitations
permit the sale of a number of shares that does not exceed the greater of 1% of
the then outstanding shares of Common Stock (approximately 78,438 shares
immediately after the offering) or the average weekly trading volume of the
Common Stock on the Nasdaq National Market during the four calendar weeks
preceding the sale, subject to the filing of a Form 144 with respect to such
sale and certain other limitations and restrictions. The Company has filed
registration statements under the Securities Act to register shares of Common
Stock reserved for issuance under its option and stock purchase plans, thus
permitting the resale of shares of Common Stock issued under these plans by
nonaffiliates in the public market without restriction under the Securities Act.
A total of 1,544,384 shares (including shares subject to outstanding options)
are reserved for issuance under the Company's Directors Stock Option Plan, 1995
Employee Stock Option Plan, Annual Leave Stock Plan, Employee Stock Purchase
Plan, Non-Employee Director Stock Purchase Plan, the Company's original
Incentive Stock Option Plan and the 1990 Incentive Stock Option Plan.
 
     The Common Stock has been included in the Nasdaq National Market since
December 16, 1994. Nevertheless, sales of substantial amounts of Common Stock in
the public market could adversely affect the prevailing market price and could
impair the Company's future ability to raise capital through an offering of its
equity securities. See "Risk Factors -- Shares Eligible for Future Sale."

     The Company and the Selling Shareholder 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 Shareholder 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 allow to selected dealers a concession of
$     per share; and that such dealers may reallow a concession of $     share
to certain other dealers. After the initial public offering, the offering price
and the concession may be changed by the Representatives.
 
     The Company and the Selling Shareholder 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 262,500 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 1,750,000.
 
     The Company and the Selling Shareholder have agreed to indemnify the
several Underwriters or contribute to losses arising out of certain liabilities,
including liabilities under the Securities Act.
 
     The Company, its executive officers and directors, and the Selling
Shareholder have agreed that they will not, 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 disposition) of any
shares of Common Stock or other capital stock of the Company, or any securities
convertible into, or exercisable or exchangeable for, any shares of Common Stock
or other capital stock of the Company, for a period of 120 days from the date of
this Prospectus, without the prior written consent of Prudential Securities
Incorporated, on behalf of the Underwriters, except that such agreement does not
prevent the Company from granting additional options under any of its Stock
Plans. See "Management -- Stock Plans."
 
     In connection with this offering, certain Underwriters and selling group
members (if any) or the respective affiliates who are qualified registered
market makers on the Nasdaq National Market, may engage in passive market making
transactions in the Common Stock of the Company on the Nasdaq National Market in
accordance with Rule 10b-6A under the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), during the two business day period before
commencement of offers or sales of the Common Stock. Passive market making
transactions must comply with applicable volume and price limits and be
identified as such. In general, a passive market maker may display its bid at a
price not in excess of the highest independent
 
                                       47

market maker's bid, however, such bid must then be lowered when certain purchase
limits are exceeded.

                          INDEPENDENT AUDITORS' REPORT
 
To The Board of Directors and Shareholders
BTG, Inc.:
 
     We have audited the consolidated financial statements of BTG, Inc. and
subsidiaries as listed in the accompanying index. 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 consolidated financial statements referred to above
present fairly, in all material respects, the financial position of BTG, Inc.,
and subsidiaries as of March 31, 1995 and 1996, and the results of their
operations and their cash flows for each of the years in the three-year period
ended March 31, 1996, in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                 MARCH 31, 1995 AND 1996 AND SEPTEMBER 30, 1996
 
1. NATURE OF OPERATIONS
 
     BTG, Inc. ("BTG" or the "Company") is an information technology company
providing complete solutions to the specific system and product needs of its
clients. The Company's business combines systems development, integration and
engineering with reselling of computer hardware, software and systems.
 
     Approximately 86%, 91%, 90%, and 90% in fiscal 1994, 1995, and 1996, and
during the six months ended September 30, 1996, respectively, of the Company's
revenue resulted from contracts or subcontracts with, and product sales to, the
U.S. Government and its agencies and departments (the "Government"). The Company
operates principally in the United States.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Principles of Consolidation
 
     The accompanying consolidated financial statements include the accounts of
all subsidiaries of the Company, each of which is wholly-owned. All significant
intercompany balances and transactions have been eliminated in consolidation.
Investments in affiliates owned more than 20%, but not in excess of 50%, are
recorded on the equity method.
 
  Interim Reporting
 
     The accompanying financial information as of September 30, 1996, and for
the six months ended September 30, 1995 and 1996, including such information
included in the Notes to Consolidated Financial Statements and disclosures
regarding matters occurring after May 10, 1996, is unaudited. In the opinion of
management, all adjustments, consisting only of normal recurring adjustments
considered necessary for a fair presentation have been included. Operating
results for any interim period are not necessarily indicative of the results for
any other interim period or for an entire year.
 
  Revenue Recognition
 
     The Company provides systems development, integration and engineering
services, primarily to the Government, on a contractual basis. Revenue on
cost-plus-fee contracts is recognized to the extent of costs incurred plus a
proportionate amount of fees earned. Revenue on time-and-materials contracts is
recognized to the extent of billable rates times hours delivered plus other
direct costs. Revenue on fixed-price contracts is recognized on the
percentage-of-completion method based on costs incurred in relation to total
estimated costs. Anticipated contract losses are recognized as soon as they
become known and estimable.
 
     Revenue that is contractually billable prior to performance or delivery is
deferred until the work has been completed.
 
     The Company also provides off-the-shelf hardware and software to the
Government under the General Services Administration ("GSA") Schedules and to
commercial companies as a third-party distributor. Related revenue is recognized
when products are shipped or when clients have accepted the products or
services, depending on contractual terms. Estimated future costs of providing
client support for products sold by the Company are recorded at the point of
revenue recognition.
 
  Cash and Equivalents
 
     All highly liquid debt instruments with original maturities of three months
or less are classified as cash equivalents (cash equivalents consist of amounts
held in money market accounts). The Company had restricted cash of approximately
$31,000, $47,000, and none at March 31, 1995 and 1996 and September 30, 1996,
respectively, relating to client agreements, which is required to be held in
escrow until related payments

to vendors have been settled and which is not included in cash and equivalents
for purposes of the Consolidated Statements of Cash Flows.
 
  Investments
 
     The Company's short-term investments, which consist solely of equity
securities, have been classified as "available for sale" in accordance with the
provisions of Statement of Financial Accounting Standards No. 115, Accounting
for Certain Investments in Debt and Equity Securities ("Statement 115").
Accordingly, such investments are carried at fair value in the accompanying
consolidated financial statements. Fair value has been determined based on
quoted market prices. Net unrealized gains and losses from these investments are
carried as a separate component of shareholders' equity, net of the related tax
effects.
 
  Inventory
 
     Inventory, net of an allowance for obsolescence, consists principally of
purchased products held for resale and is valued at the lower of cost,
determined on the average cost basis, or market value.
 
  Property and Equipment
 
     Property and equipment are recorded at cost and are depreciated over their
estimated useful lives, three to seven years, using accelerated and
straight-line methods. Leasehold improvements are amortized over the terms of
the related leases using the straight-line method.
 
  Goodwill and Intangible Assets
 
     Goodwill, the excess of cost over the fair value of net tangible and
identifiable intangible assets of acquired companies, is amortized over the
expected periods of benefit, 15 to 30 years, on a straight-line basis.
Intangible assets are amortized on a straight-line basis over the expected
periods of benefit, 2 to 13 years.
 
     The Company assesses the recoverability of its goodwill and intangible
assets by determining whether the balances can be recovered through estimated,
undiscounted future operating cash flows of the acquired operations. The amount
of impairment, if any, is measured based on projected discounted future
operating cash flows.
 
  Income Taxes
 
     Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases. Deferred tax assets and liabilities are measured using enacted tax rates
expected to apply to taxable income in the years in which those temporary
differences are expected to be recovered or settled. The effect on deferred tax
assets and liabilities of a change in tax rates is recognized in income in the
period that includes the enactment date.
 
     The Company uses the estimated annual effective rate method for interim
income tax purposes.
 
  Research and Development Expenses
 
     The Company expenses research and development costs as they are incurred.
Research and development expenses for the fiscal years ended March 31, 1994,
1995 and 1996 and the six months ended September 30, 1996 were approximately
$128,700, $100,100, $55,000, and $26,000, respectively.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
  Capitalized Product Development Costs
 
     Costs associated with software development are capitalized once a product's
technological feasibility is established. Capitalized product development costs
are amortized on a product-by-product basis based on the ratio of recorded
revenues to total estimated revenues, with a minimum amortization using a
straight-line method over a product's estimated economic life. During the six
months ended September 30, 1996, approximately $297,000 of product development
costs were capitalized (see Note 4). There were no capitalized product
development costs in fiscal 1994, 1995, and 1996.
 
  Fair Value of Financial Instruments
 
     The carrying value of the Company's cash and equivalents, receivables, and
revolving line of credit instruments approximates fair value since all such
instruments are either short-term in nature or bear interest rates which are
indexed to current market interest rates. Fair value for the Company's notes
payable is determined based on current rates offered for debt of similar
remaining maturities. At March 31, 1996 and September 30, 1996, the carrying
value of the notes payable approximated fair value.
 
  Earnings Per Share
 
     Earnings per share is computed by dividing net income for the year by the
weighted average number of shares of common stock and common stock equivalents
outstanding during the year. Common stock equivalents include all issued and
outstanding options and warrants.
 
  Reclassification
 
     Certain amounts in the prior years' financial statements have been
reclassified to conform to the fiscal year 1996 presentation.
 
  Use of Estimates
 
     The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the amounts of assets and liabilities and disclosure
of contingencies as of the dates of the financial statements, and the reported
amounts of revenue and expenses during the reporting periods. Actual results
inevitably will differ from those estimates.

     The valuation allowance for deferred tax assets as of April 1, 1994 was
$200,000. In assessing the realizability of deferred tax assets, management
considers whether it is more likely than not that some portion or all of the
deferred tax assets will be realized. The ultimate realization of the deferred
tax assets is dependent upon the generation of future taxable income during the
periods in which the temporary differences become deductible. Management
considers taxes paid during the previous three years, scheduled reversal of
deferred tax liabilities, projected future taxable income, and tax planning
strategies which can be implemented by the Company in making this assessment.
Based upon these factors, the Company has established a valuation allowance
against that portion of the deferred tax assets for which management believes
that ultimate realization cannot presently be assessed as "more likely than
not."
 
7. LINES OF CREDIT
 
     In June 1994, the Company entered into a line of credit agreement which
provided for borrowings up to $35 million. In November 1995, the Company entered
into a new revolving line of credit facility ("Credit Facility") which provides
for borrowings up to $60 million based on specified percentages of eligible
accounts receivable and inventory. All outstanding borrowings under the existing
line of credit were refinanced under this Credit Facility. The Credit Facility
is secured by substantially all assets of the Company as well as the pledge of a
security interest in the Company's stock in one of its subsidiaries. Interest on
advances made under the Credit Facility is equal to, at the option of the
Company, either the lender's prime rate or LIBOR plus 2%. Under both line of
credit agreements, the Company has been required to comply with various
financial covenants and is restricted from, among other things, paying
dividends, changing its capital structure, or making acquisitions without the
approval of the lenders. At March 31, 1995 and September 30, 1996, the Company
was in compliance with all financial covenants under the existing agreement. The
Company obtained a waiver from the lending financial institution at March 31,
1996, for non-compliance with a certain covenant under the Credit Facility. The
new revolving line of credit facility expires in August 1998. At March 31, 1996
and September 30, 1996, the entire balance outstanding under the agreement has
been

classified as a noncurrent liability in the accompanying consolidated balance
sheets as the Company anticipates that its borrowing base over the next fiscal
year will provide for a minimum availability equal to or in excess of amounts
currently outstanding. On October 1, 1996, the Credit Facility was amended to
increase the ceiling for available borrowings to $85 million through March 31,
1997 and $65 million thereafter.
 
     In addition to a revolving loan, the Credit Facility includes a facility
under which the Company can, subject to the approval of the lender and the
payment of certain fees, obtain letters of credit of up to a maximum of $1
million. At March 31, 1996 and September 30, 1996, there were no letters of
credit outstanding under this facility. Costs incurred to obtain and amend the
Credit Facility have been capitalized and are being amortized over the term of
the agreement. An analysis of the Company's line of credit activity is as

     On February 16, 1996, the Company entered into a Note and Warrant Purchase
Agreement (the "Agreement") with Nomura Holding America, Inc. under which the
Company issued $15 million of Senior Subordinated Notes (the "Notes"). The
Notes, which bear interest at 12.875% per annum, are due in

8. LONG-TERM DEBT (CONTINUED)

February 2001. In connection with the issuance of the Notes, the Company also
issued common stock purchase warrants (the "Warrants") to the holder of the
Notes entitling such holder to purchase up to 317,478 shares of the Company's
common stock at $9.50 per share, and to certain registration rights with respect
to such shares. The Warrants are exercisable at any time through February 16,
2003. Both the number of shares obtainable from exercise of the Warrants and the
exercise price per share are subject to adjustment based on certain
anti-dilution provisions included in the Agreement. The fair value of the
Warrants on the date of issuance, which was determined using various pricing
models, was estimated as $1 million. Accordingly, this amount has been recorded
as a discount on the Notes and is being amortized into interest expense over the
term of the Notes. The Agreement also contains certain covenants which, among
other matters, restrict or limit the ability of the Company to pay dividends,
incur indebtedness, and make capital expenditures. The Company must also
maintain certain financial ratios regarding interest coverage, leverage and net
worth, among others. At March 31, 1996, the Company obtained a waiver from the
holder of the Notes for non-compliance with the covenant limiting the amount of
capital expenditures made by the Company during the fiscal year. The Company was
in compliance with all covenants under the Agreement as of September 30, 1996.
Costs incurred to issue the Notes have been capitalized and are being amortized
over the term of the Notes.

31, 1996 and September 30, 1996 are as follows (in thousands):

9. SHAREHOLDERS' EQUITY AND STOCK OPTIONS
 
  Preferred Stock
 
     In November 1994, the Board of Directors amended the Company's Articles of
Incorporation to authorize up to 1,000,000 shares of preferred stock, with no
par value. No preferred shares have been issued as of September 30, 1996.
 
  Common Stock
 
     The Company has one class of voting common stock with 10 million shares
authorized for issuance. In December 1994, the Company sold 1.28 million shares
of common stock, pursuant to an initial public offering, at $8.00 per share, for
total proceeds of $8.7 million, net of issuance costs of $1.5 million.
 
  Directors Stock Option Plan
 
     During fiscal 1996, the Company adopted, subject to the approval of the
Company's shareholders, the Directors Stock Option Plan (the "Directors Option
Plan"). The Directors Option Plan provides for the granting of a maximum of
100,000 nonqualified stock options to non-employee members of the Board of
Directors. The option price per share is equal to the fair market value of a
company share on the date of grant. The term of each option is 10 years, and an
option first becomes exercisable six months after the date of grant.

9. SHAREHOLDERS' EQUITY AND STOCK OPTIONS (CONTINUED)

Under the terms of the Directors Option Plan, each non-employee member of the
Board of Directors will be granted 1,000 options on each anniversary date of the
Director's service commencement date. During fiscal 1996, 10,000 options, with a
per share exercise price of $11.25, were granted under the Directors Option
Plan. During the six months ended September 30, 1996, 6,000 options, with per
share exercise prices ranging from $13.38 to $13.75, were granted under the
Directors Option Plan. The Company's shareholders approved the Directors Option
Plan in August 1996.
 
  Employee Stock Option Plans
 
     In 1986 and again in 1990, the Company adopted qualified Employee Stock
Option Plans (the "Plans"). Under the terms of the Plans, 375,000 and 400,000
shares, respectively, of common stock were reserved for issuance under the
Plans. The option price per share is determined by the Board of Directors, but
shall be no less than the fair value on the date of the grant. Each option is
exercisable no sooner than two years and no later than five years after the
grant of the option. No new options are currently issuable under the Plans.
 
     In fiscal 1995, the Company adopted a new option plan (the "New Plan").
Under the terms of the New Plan, 250,000 shares of common stock were reserved
for issuance to employees. The New Plan provides for grants of both qualified
and non-qualified options. At March 31, 1996, 178,500 options were reserved for
future grants to employees. In August 1996, the Company's shareholders approved
an amendment to the New Plan which increased the total number of shares of
common stock reserved for issuance to 750,000. During the six months ended
September 30, 1996, options to acquire 87,500 shares of common stock were
granted under the New Plan. At September 30, 1996, 591,000 options were reserved
for future grants to employees.

  Stock Purchase Plans
 
     In fiscal 1993, the Company adopted an Employee Stock Purchase Plan (the
"Purchase Plan"). Under the terms of the Purchase Plan, 250,000 shares were
reserved for issuance. The offering price per share was to be determined by the
Board of Directors. During fiscal 1994 and 1995, 62,718 and 87,574 shares were
issued under the Purchase Plan, respectively. The Purchase Plan was terminated
during fiscal 1995.
 
     In August 1995, the Company's shareholders adopted (i) the Annual Leave
Stock Plan (the "Annual Leave Plan") and (ii) the Employee Stock Purchase Plan
(the "ESPP"). Under the Annual Leave Plan, eligible employees are permitted to
exchange certain unused amounts of accrued annual leave for shares of common
stock at the fair market value of the stock on the date of exchange. During
fiscal 1996, 10,840 shares of common stock, valued at approximately $105,000,
were issued under the Annual Leave Plan. Under the ESPP, eligible employees of
the Company who elect to participate are permitted to purchase common stock of
the Company, through payroll deductions, at a 15 percent discount from the fair
market value of such stock. The total number of shares of common stock that may
be issued under the ESPP is 150,000, limited to 12,500 per fiscal quarter. A
total of 24,979 shares were issued under the ESPP during fiscal year 1996. In
August 1996, the Company's shareholders approved an amendment to the ESPP which
(i) increased the total number of shares of common stock issuable under the ESPP
to 400,000; (ii) eliminated the quarterly purchase limitation; and (iii) added a
provision to allow for annual lump sum contributions. A total of 24,993 shares
were issued under the ESPP during the six months ended September 30, 1996.
 
     On October 15, 1996, the Company adopted, subject to the approval of the
Company's shareholders, the Non-Employee Director Stock Purchase Plan (the
"Directors Purchase Plan"). Under the terms of the Directors Purchase Plan,
non-employee members of the Board of Directors may elect to have their fees
invested in BTG common stock at a price equal to the lower of 100% of the fair
market value of a company share on the beginning or ending date of the election
period. The election period is the 12-month period beginning on October 1 of
each year. The maximum amount of shares that may be issued under the Directors
Purchase Plan is 100,000.
 
  Profit Sharing Plans
 
     The Company established a qualified 401(k) profit sharing plan in 1987
under which eligible employees may elect to defer a portion of their salary. At
the discretion of the Board of Directors, the Company may contribute to the
plan. The current contribution, as approved by the Board, is one percent of
salaries for all eligible employees and a matching contribution of an additional
amount up to three percent of eligible employees' deferrals. Employees
participating in the plan vest in the employer contribution at 20% per year,
after first completing six months of service.
 
     A subsidiary of the Company maintains a separate 401(k) profit sharing plan
which covers substantially all employees of the subsidiary meeting minimum
service requirements. Contributions to the plan are made through voluntary
employee salary reductions and are matched by the subsidiary up to a maximum of
three and one-half percent. In addition to the subsidiary matching contribution,
in which the employee is immediately vested, the plan provides for an additional
discretionary contribution by the subsidiary. Employees participating in the
plan vest in the employer discretionary contributions over a seven year period.
 
     Company contributions to the profit sharing plans were $539,900, $732,000,
$1.1 million and $986,000 in fiscal 1994, 1995 and 1996, and the six months
ended September 30, 1996, respectively.

  Impact of Statement of Financial Accounting Standards No. 123
 
     In October 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 123, Accounting for Stock-Based
Compensation ("Statement 123"). Statement 123 provides companies with the option
to choose between a fair value based method of accounting for its stock-based
compensation arrangements or retaining an intrinsic value-based method as is
required under current accounting standards. Under Statement 123, companies that
elect to retain the traditional intrinsic value-based methods of accounting for
their stock-based compensation arrangements will be required to provide expanded
disclosures in the footnotes accompanying their basic financial statements. The
provisions of Statement 123 are effective for the Company's fiscal 1997
financial statements. As permitted by Statement 123, the Company will adopt the
new standard in fiscal 1997 and will choose to continue the current intrinsic
value-based method of accounting for stock-based compensation. Accordingly, the
Company will disclose in the notes to the 1997 consolidated financial
statements, the pro forma net income and earnings per share calculated using the
fair value-based method of accounting.
 
10.  INVESTMENTS IN AFFILIATES
 
     In September 1993, the Company entered into an agreement to sell BDS
Systems, Inc., a subsidiary which was involved in medical imaging, to the
subsidiary's former president in exchange for stock owned in the Company. The
estimated fair value of the shares acquired approximated the fair value of the
net assets sold and the associated goodwill carried on the Company's records,
and no gain or loss was recognized.
 
     In fiscal 1994, the Company wrote off $397,000 of its remaining unamortized
goodwill related to a previously acquired subsidiary.
 
     On May 2, 1996, the Company entered into an agreement with WheelGroup
Corporation ("WheelGroup") under which it (i) purchased 214,042 shares of the
outstanding common stock of WheelGroup for $200,000; (ii) purchased a
convertible note receivable from WheelGroup for $300,000; and (iii) committed to
the purchase of certain distribution rights and consulting services from
WheelGroup for approximately $1 million, payable in various installments over
fiscal 1997 and 1998. The convertible note, which bears interest at an annual
rate of 2% above the prime rate established by the Company's principal lender,
is convertible at any time at the Company's option. The convertible note is due
in quarterly installments beginning on April 1, 1999 and ending on January 2,
2001. During the six months ended September 30, 1996, the Company paid
approximately $350,000 for consulting services to this company. The Company's
equity investment under this arrangement was accounted for using the cost method
during the six months ended September 30, 1996.
 
     A subsidiary of the Company has a 49% interest in an unincorporated joint
venture (the "Joint Venture"). The Joint Venture was formed with an unrelated
company in February 1994 for the purpose of performing under a contract to
provide certain computer equipment, software and peripherals to the government.
The equity method is used to account for the Company's interest in the Joint
Venture. At March 31, 1996 and September 30, 1996, the Company's investment in
the Joint Venture was approximately $623,000 and $561,000, respectively, and is
included in other noncurrent assets in the accompanying consolidated balance
sheets.

11. BUSINESS COMBINATIONS
 
     In July 1994, the Company acquired for $1.9 million cash all of the
outstanding stock of Advanced Computer Technology, Inc., ("ACTech"), a
value-added reseller and manufacturer of computer systems. The acquisition has
been accounted for as a purchase and, accordingly, the results of operations of
ACTech have been included in the Company's consolidated financial statements
from the date of acquisition, July 1, 1994. The excess of the purchase price
over the fair value of the net tangible and identifiable intangible assets
acquired of approximately $1.1 million has been recorded as goodwill and is
being amortized on a straight-line basis over 15 years. In connection with the
closing of the transaction, the Company entered into certain non-compete
agreements which require payments to former ACTech officers over a three-year
period. At March 31, 1995 and 1996, and September 30, 1996, $83,000, $17,000,
and $17,000, respectively, were outstanding under these agreements. This
acquisition did not have a material effect on pro forma operations.
 
     In November 1994, the Company acquired for $2.8 million cash all of the
outstanding stock of Delta Research Corporation ("Delta"), which provides
software development and systems integration services focusing on project
planning and cost controls and environmental engineering, primarily for the
government. The acquisition has been accounted for as a purchase and,
accordingly, the results of operations of Delta have been included in the
Company's consolidated financial statements from the date of acquisition,
November 15, 1994. The excess of the purchase price over the fair value of the
net tangible and identifiable intangible assets acquired of approximately
$146,000 has been recorded as goodwill and is being amortized on a straight-line
basis over 15 years. In connection with the closing of the transaction, the
Company entered into certain non-compete agreements which require payments of
$100,000 per year for four years.
 
     In October 1995, the Company acquired, for $13.0 million in cash, 50,057
shares of common stock valued at approximately $463,000, and $1.25 million due
in April 1996, all of the outstanding shares of Concept Automation, Inc. of
America ("CAI"), which is primarily involved in the sale and maintenance of
electronic data processing equipment and related support services. The
acquisition has been accounted for as a purchase and, accordingly, the results
of operations of CAI have been included in the Company's consolidated financial
statements from the date of acquisition, October 20, 1995. The excess of the
purchase price over the fair value of the net tangible and identifiable
intangible assets acquired of approximately $11.5 million has been recorded as
goodwill and is being amortized on a straight-line basis over 20 years. In
connection with the closing of the transaction, the Company entered into various
employment and non-compete agreements with certain of CAI's officers. In
addition, the agreement provides that certain contingent payments are to be made
to the former shareholders of CAI in the event that future income is generated
under a specific contract for which CAI had a proposal outstanding on the date
of acquisition. At March 31, 1996, no amounts have been included in the purchase
price relating to these contingent payments. On April 18, 1996, the Company was
notified that this contract was awarded to CAI. During the six months ended
September 30, 1996, no amounts have been paid to the former shareholders of CAI
as a result of this arrangement.

  Audit Review
 
     Substantially all payments to the Company under cost-reimbursable
government contracts are provisional payments which are subject to adjustment
upon audit by the Defense Contract Audit Agency or other regulatory agency. At
March 31, 1996, audits through fiscal 1989 had been completed and final rates
established. During the six months ended September 30, 1996, audits were
completed for fiscal 1990, 1991, and 1992. Audits for 1993 and subsequent years
are not expected to result in a material adverse effect on the Company's
consolidated financial position.
 
     In addition, product sales under GSA Schedule contracts may also be subject
to audit by the GSA. One of the Company's GSA Schedule contracts was audited
during fiscal 1996 and the Company was recently notified that the customer was
seeking to recover approximately $156,000 as a result of the audit. The Company
disagrees with certain of the claims made under the audit and intends to
vigorously defend its position through the appeals process. Management of the
Company believes that sufficient reserves are available to offset any potential
adjustments.
 
  Leases
 
     The Company leases office space and equipment under certain operating lease
agreements expiring at various dates through March 2003. Most leases include
provisions for periodic rent escalations based on changes in various economic
indices. Rent expense in fiscal 1994, 1995 and 1996 was $2.3 million, $2.8
million, and $4.8 million, respectively. During the six months ended September
30, 1996, rent expense was $2.6 million. The facility lease for the Company's
primary headquarters location is scheduled to terminate in March 1997.

                          INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors and Shareholders
Concept Automation, Inc. of America
Sterling, Virginia
 
     We have audited the accompanying consolidated balance sheets of Concept
Automation, Inc. of America and its wholly-owned subsidiary as of December 31,
1993 and 1994, and the related consolidated statements of operations and
retained earnings and cash flows for the years then ended. These financial
statements are the responsibility of the Corporation's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Concept Automation, Inc. of
America and its wholly-owned subsidiary as of December 31, 1993 and 1994, and
the consolidated results of operations and cash flows for the years then ended,
in conformity with generally accepted accounting principles.

                      CONCEPT AUTOMATION, INC. OF AMERICA
                        AND ITS WHOLLY-OWNED SUBSIDIARY
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                           DECEMBER 31, 1993 AND 1994
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     The accounting and reporting policies of Concept Automation, Inc. of
America and its consolidated subsidiary corporation conform with generally
accepted accounting principles and reflect practices appropriate to the
government contracting industry. These policies are summarized below.
 
     Certain amounts for 1993 have been reclassified to make them comparable
with the current period.
 
  Principles of Consolidation
 
     The consolidated financial statements include the accounts of Concept
Automation of America, Inc. and its wholly-owned subsidiary Concept Automation
Services, Inc. All material intercompany accounts and transactions have been
eliminated.
 
  Cash and Cash Equivalents
 
     Cash equivalents include cash in banks and daily repurchase agreements. The
Corporations typically maintain balances on deposit in banks in excess of
insured amounts.
 
     Interest paid amounted to $393,911 and $381,223 in 1993 and 1994. Income
taxes paid in 1993 and 1994 amounted to $345,880 and $614,938, respectively.
 
  Revenue Recognition
 
     Revenue from the sale of electronic data processing equipment is recorded
at the time of transfer of title. Revenue from services such as installation,
training, maintenance, and other services are recognized as the services are
rendered. Revenue from the lease of systems and equipment is recognized over the
term of the lease. Revenue from time-and-materials contracts is recognized by
the unit-of-completion method as billable units are completed. Revenue from
fixed-price contracts is recognized by the unit-of-completion method as billable
units are completed. Costs and expenses are recorded as incurred.
 
     At the time a loss on a contract becomes known, the entire amount of the
estimated ultimate loss is accrued.
 
  Accounts Receivable
 
     Most revenue and contract revenue receivables are related to contracts and
subcontracts with the Federal government.
 
     All accounts receivable are expected by management to be fully collectible;
therefore, no allowance for doubtful receivables is maintained.
 
  Inventory
 
     The inventory of electronic data processing equipment and related items is
valued at the lower of average cost or market.
 
  Property and Equipment

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

     Depreciation and amortization are computed under the straight-line method
for leasehold improvements and accelerated methods for other items. Depreciation
and amortization expense was $295,744 and $237,047 in 1993 and 1994,
respectively.
 
  Investment
 
     The Corporations purchased 12,500 shares, at $8.00 per share, of DMS
Systems, Inc., a closely held company, on December 11, 1986. The shares
purchased represented 7 percent of the outstanding shares of DMS Systems, Inc.
During 1993, DMS Systems was purchased by Openvision in exchange for options to
purchase Openvision shares as well as an undetermined amount of money based on
collection of DMS accounts receivable and royalties on DMS products. The
Corporations received $10,228 through December 31, 1993. The carrying value of
the investment has been reduced to zero at December 31, 1994.
 
  Software and Related Licenses
 
     Software and related licenses are recorded at cost and are being amortized
over five years using the straight-line method. Amortization expense was $54,528
and $23,305 in 1993 and 1994, respectively.
 
  Compensated Absences
 
     The Corporations have accrued the obligation relating to employees'
compensation for future absences attributable to services already rendered.
 
  401(k) Profit Sharing Plan
 
     The Corporations maintain a 401(k) profit sharing plan covering all
employees meeting minimum service requirements. Contributions to the plan are
through voluntary employee salary reductions. The Corporations are required to
match employee contributions by establishing the matching percentage of
compensation annually up to a maximum of 3.5% of covered compensation.
 
  Income Taxes
 
     Effective January 1, 1993, the Corporations adopted Statement of Financial
Accounting Standards No. 109, Accounting for Income Taxes. FASB Statement No.
109 utilizes an asset and liability approach to accounting for income taxes. The
objective is to recognize the amount of income taxes payable or refundable in
the current year based on the Corporations' income tax returns and the deferred
tax liabilities and assets for the expected future tax consequences of events
that have been recognized in the Corporation's financial statements or tax
returns. The asset and liability method accounts for deferred income taxes by
applying enacted statutory rates to temporary differences, the difference
between financial statement amounts and tax bases of assets and liabilities. The
resulting deferred tax liabilities or assets are classified as current or
noncurrent based on the classification of the related asset or liability.
Deferred income tax liabilities or assets are adjusted to reflect changes in tax
laws or rates in the year of enactment.
 
     Temporary differences result from accrued expenses and different methods of
valuing inventory for the financial statements and tax returns.
 
     A consolidated Federal income tax return is filed for Concept Automation,
Inc. and its subsidiary corporation. Consolidated income tax returns are also
filed in Virginia and Oklahoma. Other state tax returns required for the
Corporations are unconsolidated.

4. FLOOR PLAN AND ACCOUNTS RECEIVABLE LINES OF CREDIT
 
     The Corporations have agreements with a financing organization to borrow up
to $15.0 million to finance floor plan inventory purchases and accounts
receivable. Floor plan borrowings are collateralized by most of the assets of
the Corporations and accounts receivable borrowings are collateralized by
accounts receivable and inventory not encumbered under the floor plan agreement.
The floor plan agreement specifies repayment terms of 60 days after which
interest is charged at a rate of 0.25% plus a per annum rate of Chase
Manhattan's prime rate plus 2.50%. Interest on accounts receivable borrowing is
payable monthly at Chase Manhattan's prime rate plus 1.00% per annum with a
minimum of 6.50%. Starting on January 1, 1995, the interest rate charged for
financing accounts receivable is Chase Manhattan's prime rate plus 0.50%.
 
     The agreements, which include restrictive financial covenants, remain in
force until one of the parties gives notice that they are terminated. The
Corporations have violated certain covenants and the lender has waived
compliance.
 
     The balances under the above agreements are as follows at December 31:

              NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED
                              FINANCIAL STATEMENTS
 
1. COMPANY HISTORICAL
 
     The historical balances of the Company represent the consolidated financial
position and results of operations as of September 30, 1996 and for the six
months then ended as reported in the historical consolidated financial
statements of BTG, included elsewhere in this Prospectus. The acquisition of
CAI, which occurred in October 1995, is fully reflected in such historical
balances.
 
2. BTG HISTORICAL
 
     The historical balances of BTG represent the results of operations for the
fiscal year ended March 31, 1996, as reported in the historical consolidated
financial statements of BTG, included elsewhere in this Prospectus. These
balances include the results of operations of CAI from October 20, 1995, the
date of acquisition, through March 31, 1996.
 
3. CAI ACQUISITION
 
     On October 20, 1995, BTG acquired, for $13.0 million in cash, 50,057 shares
of BTG common stock valued at approximately $463,000, and $1.25 million due in
April 1996, all of the outstanding shares of CAI. The acquisition was accounted
for using the purchase method of accounting. The excess of the purchase price
over the fair value of the net tangible and identifiable intangible assets
acquired of approximately $11.5 million was recorded as goodwill and is being
amortized on a straight-line basis over 20 years. In connection with the closing
of the transaction, BTG entered into various employment and non-compete
agreements with certain of CAI's officers. In addition, the agreement provides
that certain contingent payments are to be made to the former shareholders of
CAI in the event that future income is generated under a specific contract for
which CAI had a proposal outstanding on the date of acquisition. No amounts
relating to these contingent payments have been included in the purchase price.
On April 18, 1996, BTG was notified that this contract was awarded to CAI.
 
     The historical balances of CAI represent the results of operations for the
period from April 1, 1995 through October 20, 1995, the date of acquisition.
Certain amounts in CAI's historical financial statements have been reclassified
to conform to the presentation used in the unaudited pro forma condensed
consolidated financial statements.
 
4. PRO FORMA ADJUSTMENTS
 
     The following pro forma adjustments are reflected as of September 30, 1996,
in the case of the unaudited pro forma condensed consolidated balance sheet; as
of April 1, 1996, in the case of the unaudited pro forma condensed consolidated
statement of operations for the six months ended September 30, 1996; and as of
April 1, 1995, in the case of the unaudited pro forma condensed consolidated
statement of operations for the fiscal year ended March 31, 1996:
 
     (A) Reduction of outstanding borrowings under BTG's Credit Facility and a
corresponding increase in shareholders' equity resulting from the assumed
application of the net proceeds of the Offering.
 
     (B) Reduction of interest expense on all borrowings assumed to be repaid
with the net proceeds of the Offering (using an effective annual interest rate
of 7.49%).
 
     (C) Additional federal and state income tax expense resulting from the
reduction of interest expense in the six months ended September 30, 1996, and
from the reduction of both interest expense and general and administrative costs
in fiscal 1996.
 
     (D) Reduction of general and administrative expenses attributable to new
employment arrangements with members of CAI senior management.

                              FINANCIAL STATEMENTS
 
4. PRO FORMA ADJUSTMENTS (CONTINUED)
     (E) Amortization of identifiable intangible assets on a straight-line basis
over two years and goodwill on a straight-line basis over twenty years.
 
     (F) Interest expense on borrowings needed to fund the cash portion of the
CAI purchase price ($592,000 using an effective annual interest rate of 8.40%
for the period from April 1, 1995 through October 20, 1995), adjusted for the
elimination of interest expense on all borrowings assumed to be repaid with the
net proceeds of the Offering ($2.1 million using an effective annual interest
rate of 8.05%).
 
5. PRO FORMA NET INCOME PER SHARE
 
     Pro forma net income per share is computed by dividing pro forma net income
by BTG's historical number of weighted average shares of common stock and common
stock equivalents outstanding after giving effect to the 50,057 shares of BTG
common stock issued to fund the stock portion of the purchase price and the
1,670,000 shares of BTG common stock issued in connection with the Offering.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Article 10 of the Company's Amended Articles provides that the Company
will, to the fullest extent permitted by the laws of Virginia, indemnify an
individual who is or was a director or officer of the Company and who was, is,
or is threatened to be made a named defendant or respondent in any threatened,
pending or completed action, suit, or proceeding, whether civil, criminal,
administrative or investigative and whether formal or informal (collectively, a
"proceeding"), against any obligation to pay a judgment, settlement, penalty,
fine (including any excise tax assessed with respect to any employee benefit
plan) or other liability and reasonable expenses (including counsel fees)
incurred with respect to such a proceeding, except such liabilities and expenses
as are incurred because of such director's or officer's willful misconduct or
knowing violation of the criminal law.
 
     Article 10 also provides that unless a determination has been made that
indemnification is not permissible, the Company will make advances and
reimbursements for expenses reasonably incurred by a director or officer in a
proceeding as described above upon receipt of an undertaking from such director
or officer to repay the same if it is ultimately determined that such director
or officer is not entitled to indemnification.
 
     Article 10 also provides that the determination that indemnification under
such Article 10 is permissible, the authorization of such indemnification (if
applicable), and the evaluation as to the reasonableness of expenses in a
specific case shall be made as provided by law. Special legal counsel selected
to make determinations under such Article 10 may be counsel for the Company. The
termination of a proceeding by judgment, order, settlement, conviction, or upon
a plea of nolo contendere or its equivalent will not of itself create a
presumption that a director or officer acted in such a manner as to make him or
her ineligible for indemnification.
 
     For the purposes of Article 10, every reference to a director or officer
includes, without limitation, (i) every individual who is a director or officer
of the Company, (ii) an individual who, while a director or officer, is or was
serving at the Company's request as a director, officer, partner, trustee,
employee or agent of another foreign or domestic corporation, partnership, joint
venture, trust, employee benefit plan or other enterprise, (iii) an individual
who formerly was a director or officer of the Company or who, while a director
or officer, occupied at the request of the Company any of the other positions
referred to in clause (ii) of this sentence, and (iv) the estate, personal
representative, heirs, executors and administrators of a director or officer of
the Company or other person referred to herein. Service as a director, officer,
partner, trustee, employee or agent of another foreign or domestic corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise
controlled by the Corporation shall be deemed service at the request of the
 
                                      II-1
<PAGE>   88
 
Company. A director or officer shall be deemed to be serving an employee benefit
plan at the Company's request if such person's duties to the Company also impose
duties on, or otherwise involve services by, such person to the plan or to
participants in or beneficiaries of the plan.
 
     Section 13.1-704(B) of the Virginia Stock Corporation Act provides that a
corporation may provide indemnification and make provision for advances and
reimbursement of expenses so long as the party who is seeking indemnification,
advances or reimbursement did not commit willful misconduct or a knowing
violation of criminal law.
 
     As provided in Section 8 of the Underwriting Agreement, each Underwriter
has agreed, under certain conditions, to indemnify the Company, each of its
directors, each of its officers who has signed the Registration Statement and
each person who controls the Company within the meaning of the Securities Act of
1933, against certain civil liabilities, including certain civil liabilities
under the Act.
 
     As of the date hereof, the Company had purchased directors and officers
liability insurance in the amount of $5.0 million.

     exercised. Options to acquire an additional 38,590 shares remain to be
     exercised.
 
          4. Under the FY 1994 Employee Stock Purchase Plan, 72 employees of the

     were granted to officers and employees of the Company at exercise prices
     ranging from $3.00 to $3.80 per share, and, during the same period, ISOs to
     purchase a total of 67,391 shares under such plan were exercised at prices
     ranging from $3.00 to $3.80 per share.
 
          7. On October 29, 1993 an officer of the Company exercised an option
     to purchase a total of 50,000 shares of Common Stock at an exercise price
     of $3.45 per share.
 
          8. In connection with the Company's former Annual Leave Stock Plan,
     between October 1, 1993 and January 1, 1995, the Company issued and sold a
     total of 9,105 shares of Common Stock to 11 employees at $3.45 per share.
     Under this plan, the consideration for such shares was accrued vacation
     time.
 
          9. On March 31, 1994, four persons purchased 29,000 shares of Common

     America Inc. in a private placement.
 
     No underwriters were engaged in connection with the foregoing sales and/or
issuances of securities. Such sales were made in reliance upon the exemption
from the registration provisions of the Securities Act set forth in Rule 701
thereunder permitting unregistered sales to employees and consultants, and/or in
Section 4(2) thereof as transactions not involving a public offering, the
respective purchasers thereof having acquired such shares for their respective
accounts without a view to the distribution thereof.

ITEM 17. UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes to provide to the Underwriters
at the closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant under the provisions referred to in Item 14 of this Registration
Statement, or otherwise, the Registrant has been advised that in the opinion of
the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by a director, officer or
controlling person of the 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.
 
     The undersigned Registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this Registration Statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be a part of this
     Registration Statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

         2.      Representations and Warranties of the Company and the Selling
                 Securityholder.

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

         (i)     A registration statement on Form S-1 (File No. 33-_________)
with respect to the Securities, including a prospectus subject to completion,
has been filed by the Company with the Securities and Exchange Commission (the
"Commission") under the Securities Act of 1933, as amended (the "Act"), and one
or more amendments to such registration statement may have been so filed.
After the execution of this Agreement, the Company will file with the
Commission either (A) if such registration statement, as it may have been
amended, has been declared by the Commission to be effective under the Act,
either (1) if the Company relies on Rule 434 under the Act, a Term Sheet (as
hereinafter defined) relating to the Securities, that shall identify the
Preliminary Prospectus (as hereinafter defined) that it supplements containing
such information as is required or permitted by Rules 434, 430A and 424(b)
under the Act or (2) if the Company does not rely on Rule 434 under the Act, a
prospectus in the form most recently included in an amendment to such
registration statement (or, if no such amendment shall have been filed, in such
registration statement), with such changes or insertions as are required by
Rule 430A under the Act or permitted by Rule 424(b) under the Act, and in the
case of either clause (A)(1) or (A)(2) of this sentence as have been provided
to and approved by the Representatives prior to the execution of this
Agreement, or (B) if such registration statement, as it may have been amended,
has not been declared by the Commission to be effective under the Act, an
amendment to such registration statement, including a form of prospectus, a
copy of which amendment has been furnished to and approved by the
Representatives prior to the execution of this Agreement.  The Company may also
file a related registration statement with the Commission pursuant to Rule
462(b) under the Act for the purpose of registering certain additional
Securities, which registration shall be effective upon filing with the
Commission.

As used in this Agreement, the term "Original Registration Statement" means the
registration statement initially filed relating to the Securities, as amended
at the time when it was or is declared effective, including all financial
schedules and exhibits thereto and including any information omitted therefrom
pursuant to Rule 430A under the Act and included in the Prospectus (as
hereinafter defined); the term "Rule 462(b) Registration Statement" means any
registration statement filed with the Commission pursuant to Rule 462(b) under
the Act (including the Registration Statement and any Preliminary Prospectus or
Prospectus incorporated therein at the time such Registration Statement becomes
effective); the term "Registration Statement" includes both the Original
Registration Statement and any Rule 462(b) Registration Statement;  the term
"Preliminary Prospectus" means each prospectus subject to completion filed with
such registration statement or any amendment thereto (including the prospectus
subject to completion, if any, included in the Registration Statement or any
amendment thereto at the time it was or is declared effective); the term
"Prospectus" means:

(I)      if the Company relies on Rule 434 under the Act, the Term Sheet
         relating to the Securities that is first filed pursuant to Rule
         424(b)(7) under the Act, together with the Preliminary Prospectus
         identified therein that such Term Sheet supplements;

(II)     if the Company does not rely on Rule 434 under the Act, the prospectus
         first filed with the Commission pursuant to Rule 424(b) under the Act;
         or

(III)    if the Company does not rely on Rule 434 under the Act and if no
         prospectus is required to be filed pursuant to Rule 424(b) under the
         Act, the prospectus included in the Registration Statement;





                                      -2-
<PAGE>   3
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.

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

         (iii)  If the Company has elected to rely on Rule 462(b) and the Rule
462(b) Registration Statement has not been declared effective (A) the Company
has filed 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 (B) the Company has given irrevocable instructions for
transmission of the applicable filing fee in connection with the filing of the
Rule 462(b) Registration Statement, in compliance with Rule 111 promulgated
under the Act or the Commission has received payment of such filing fee.

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

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





                                      -3-

         (vi)    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.

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

         (viii)  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.

         (ix)    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.

         (x)     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 captions "Summary Consolidated Financial Data" and
"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.

         (xi)    KPMG Peat Marwick LLP, 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.

         (xii)   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





                                      -4-

agreement of the Company, enforceable against the Company in accordance with
its terms, except as enforcement thereof may be limited by bankruptcy,
insolvency, reorganization, moratorium, fraudulent conveyance, receivership,
conservatorship or other similar laws, regulations or procedures of general
applicability relating to or affecting enforcement of the rights of creditors
of savings or by general equity principles and the discretion of the court
before which any proceeding is brought (regardless of whether enforceability is
considered in a proceeding in equity or at law) and except as the obligations
of the Company under the indemnification and contribution provisions hereof may
be limited by public policy under certain circumstances, including applicable
federal or state securities laws.

         (xiii)  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
Prospectus), and, to the Company's knowledge, 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.

         (xiv)   The issuance, offering and sale of the Securities to the
Underwriters by the Company pursuant to this Agreement, the compliance by the
Company with the other provisions of this Agreement and the consummation of the
other transactions herein contemplated do not (A) require the consent,
approval, authorization, registration or qualification of or with any
governmental authority, except such as have been obtained, such as may be
required under state securities or blue sky laws and, if the Registration
Statement is not effective under the Act as of the time of execution hereof,
such as may be required (and shall be obtained as provided in this Agreement)
under the Act, or (B) conflict with or result in a breach or violation of any
of the terms and provisions of, or constitute a default under, any material
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.

         (xv)    No default exists, and no event has occurred which, with
notice or lapse of time or both, would constitute a default in the due
performance and observance of any term, covenant or condition of any indenture,
mortgage, deed of trust, lease or other agreement or instrument to which the
Company or any of its subsidiaries is a party or by which the Company or any of
its subsidiaries or any of their respective properties is bound or may be
affected in any material adverse respect with regard to property, business or
operations of the Company and its subsidiaries.

given in the Registration Statement and the Prospectus or, if the Prospectus is
not in existence, the most recent Preliminary Prospectus, (A) 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

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; (B) neither the Company nor any of its
subsidiaries have incurred any material liability or obligation, direct or

paid or otherwise made any dividend or distribution of any kind on its capital
stock; and (D) there has not been any material change in the capital stock,
short-term debt or long-term debt of the Company and its 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.

         (xvii)  The Company has not, directly or indirectly, (A) taken any
action designed to cause or to result in, or that has constituted or which
might reasonably be expected to constitute, the stabilization or manipulation
of the price of any security of the Company to facilitate the sale or resale of
the Securities or (B) since the filing of the Registration Statement (1) sold,
bid for, purchased, or paid anyone any compensation for soliciting purchases
of, the Securities or (2) paid or agreed to pay to any person any compensation
for soliciting another to purchase any other securities of the Company (except
for the sale of Securities by the Selling Securityholder under this Agreement).

         (xviii) None of the Company, its subsidiaries or any employee of the
Company or its subsidiaries has made any payment of funds of the Company or its
subsidiaries prohibited by any applicable law and no funds of the Company or
its subsidiaries have been set aside to be used for any payment prohibited by
any such law.

         (xix)   The Company and each of its subsidiaries have good and
marketable title in fee simple to all items of real property and marketable
title to all personal property owned by each of them, in each case free and
clear of any security interests, liens, encumbrances, equities, claims and
other defects, except such as do not materially and adversely affect the value
of such property and do not interfere with the use made or proposed to be made
of such property by the Company or such subsidiary, and any real property and
buildings held under lease by the Company or any such subsidiary are held under
valid, subsisting and enforceable leases, with such exceptions as are not
material and do not interfere with the use made or proposed to be made of such

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

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

         (xxi)   The Company and each of its subsidiaries are insured by
insurers of recognized financial responsibility against such losses and risks
and in such amounts as are prudent and customary in the businesses in which
they are engaged; neither the Company nor any such subsidiary has been refused
any insurance coverage sought or applied for; and neither the Company nor any
such subsidiary has any reason to believe that it will not be able to renew its
existing insurance coverage as and when such coverage expires or to obtain
similar coverage from similar insurers as may be necessary to continue its
business at a cost that would not materially and adversely affect the condition
(financial or otherwise), business prospects, net worth or results of

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

         (xxiv)  The Company is not an investment company under the Investment

(except in any case in which the failure so to file would not have a material
adverse effect on the Company and its subsidiaries) and has paid all taxes
required to be paid by it and any other assessment, fine or penalty levied
against it, to the extent that any of the foregoing is due and payable, except

licenses or other approvals required of them under applicable federal and state
occupational safety and health and environmental laws and regulations to

contemplated by the Prospectus (or, if the Prospectus is not in existence, the
most recent Preliminary Prospectus).

will not distribute any offering material in connection with the offering and
sale of the Securities other than the Registration Statement or any amendment

acquire on reasonable terms, all material patents, patent applications,
trademarks, service marks, trade names, licenses, copyrights and proprietary or
other confidential information (collectively, the "Intellectual Property")
currently employed by them in connection with their respective businesses, and
neither the Company nor any such subsidiary has received any notice of
infringement of or conflict with asserted rights of any third party with
respect to any of the foregoing which, singly or in the aggregate, if the
subject of an unfavorable decision, ruling or finding, would result in a
material adverse change in the condition (financial or otherwise), business
prospects, net worth or results of operations of the Company and its
subsidiaries, except as described in or contemplated by the Prospectus (or, if
the Prospectus is not in existence, the most recent Preliminary Prospectus).

         (xxxii) All patents, patent applications, trademark registrations,
trademark applications and registered copyrights which are owned by the Company
and its subsidiaries have been duly registered in, filed in or issued by the
United States Patent and Trademark Office, the United States Register of
Copyrights, or the corresponding offices of other jurisdictions, and have been
properly maintained and renewed in accordance with all applicable provisions of
law and administrative regulations of the United States and each such
jurisdiction.

         (xxxiii) All licenses or other agreements under which the Company or
its subsidiaries are granted rights in Intellectual Property are in full force
and effect, except for those licenses or other agreements which are not
material to the Company or its subsidiaries and there is no default by any
party thereto which default could reasonably be expected to result in a
material adverse change in the condition (financial or otherwise), business
prospects, net worth or results of operations of the Company and its
subsidiaries.  To the Company's and the Selling Securityholder's knowledge, the
licensors under said licenses and other agreements have and had all requisite
power and authority to grant the rights purported to be conferred thereby, to
the extent material with respect to the Company and its subsidiaries.  All
licenses or other agreements under which the Company or its subsidiaries have
granted rights to others in Intellectual Property owned or licensed by the
Company or its subsidiaries are in full force and effect, except for those
licenses or other agreements which are not material to the Company or its
subsidiaries and there is no default by any party thereto which default could
reasonably be expected to result in a material adverse change in the condition
(financial or otherwise), business prospectus, net worth or results of
operations of the Company and its subsidiaries.
                  
         (xxxiv) The Company and its subsidiaries have taken reasonable steps
in accordance with sound business practice to establish and preserve its
ownership of all material Intellectual Property rights with respect to its
products, services and technology.  Except for those instances which could not
reasonably be





                                      -8-
<PAGE>   9
expected to have a material adverse effect on the condition (financial or
otherwise), business prospects, net worth or results of operations of the
Company and its subsidiaries, the Company and its subsidiaries have required
all employees having access to non-public information of the Company and its
subsidiaries to execute agreements under which such employees are required to
convey to the Company ownership of all inventions and developments conceived or
created by them in the course of their employment and to maintain the
confidentiality of all such information of the Company.  Except for those
instances which could not reasonably be expected to have a material adverse
effect on the condition (financial or otherwise), business prospects, net worth
or results of operations of the Company and its subsidiaries, the Company and
its subsidiaries have not made any such information available to any person
other than employees of the Company or its subsidiaries except pursuant to
written agreements requiring the recipients to maintain the confidentiality of
such information and appropriately restricting the use thereof.  The Company
has no knowledge of any infringement by others of any Intellectual Property
rights of the Company or its subsidiaries which infringement could reasonably
be expected to result in a material adverse change in the condition (financial
or otherwise), business prospectus, net worth or results of operations of the
Company and its subsidiaries.

agrees with, each of the several Underwriters that:

Custodian pursuant to the Custody Agreement and Power of Attorney for the
purpose of delivery pursuant to this Agreement.  The Selling Securityholder has

Securityholder and, assuming due authorization, execution and delivery by the
Custodian, are the legal, valid, binding and enforceable instruments of the
Selling Securityholder.  The Selling Securityholder 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

otherwise, whether by the death or incapacity of the Selling Securityholder or
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.  If the
Selling Securityholder, or any trustee or executor should die or become
incapacitated or any such trust should be terminated, 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





                                      -9-
<PAGE>   10
delivered by the Custodian in accordance with the respective terms and
conditions of this Agreement as if such death, incapacity, termination or other
event had not occurred, regardless of whether or not the Custodian or the
Attorneys-in-Fact shall have received notice thereof.

         (iii)   The Selling Securityholder is the lawful owner of the
Securities to be sold by the Selling Securityholder hereunder and upon sale and
delivery of, and payment for, such Securities, as provided herein, the Selling
Securityholder will convey good and marketable title to such Securities, free
and clear of any security interests, liens, encumbrances, equities, claims or
other defects.

         (iv)    The Selling Securityholder has not, directly or indirectly,

or resale of the Securities or (B) since the filing of the Registration
Statement (1) sold, bid for, purchased, or paid anyone any compensation for
soliciting purchases of, the Securities or (2) paid or agreed to pay to any
person any compensation for soliciting another to purchase any other securities

under this Agreement).

         (v)     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 the Selling Securityholder 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.
The Selling Securityholder 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 the Selling
Securityholder set forth therein under the caption "Principal and Selling
Stockholders" is complete and accurate.

         (vi)    The Selling Securityholder has not distributed and, prior to
the later of (A) the Closing Date and (B) the completion of the distribution of
the Securities, will not distribute any offering material in connection with
the offering and sale of the Securities other than the Registration Statement
or any amendment thereto, any Preliminary Prospectus and the Prospectus or any

Act.

         (vii)   In order to document the Underwriters' compliance with the

Securityholder agrees to deliver to you prior to or on the Firm Closing Date,
as hereinafter defined, a properly completed and executed United States

Securityholder pursuant to this Agreement, the compliance by the Selling
Securityholder with the other provisions of this Agreement, the Custody
Agreement and the consummation of the other transactions herein contemplated do
not (A) require





                                      -10-
<PAGE>   11
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 is not effective under the Act as of the time of execution hereof,
such as may be required (and shall be obtained as provided in this Agreement)
under the Act, or (B) conflict with or result in a breach or violation of any
of the terms and provisions of, or constitute a default under any indenture,
mortgage, deed of trust, lease or other agreement or instrument to which the
Selling Securityholder is a party or by which the Selling Securityholder or any
of the Selling Securityholder's properties are bound, or any statute or any
judgment, decree, order, rule or regulation of any court or other governmental
authority or any arbitrator applicable to the Selling Securityholder.

         3.      Purchase, Sale and Delivery of the Securities. (a) On the
basis of the representations, warranties, agreements and covenants herein

and the Selling Securityholder agree, severally and not jointly, to issue (in

Underwriters, severally and not jointly, agrees to purchase from the Company
and the Selling Securityholder, at a purchase price of $____ per share, the

Securityholder's name on Schedule 2 hereto.  One or more certificates in
definitive form for the Firm Securities that the several Underwriters have

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 Securityholder 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 account of the

Firm Securities shall be made at the offices of Willkie Farr & Gallagher, One
Citicorp Center, 153 East 53rd Street, New York, New York at 9:30 A.M., New
York time, on November ___, 1996, or at such other place, time or date as the

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

         (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 the Selling Securityholder hereby grant to the
several Underwriters options to purchase, severally and not jointly, the Option
Securities. The purchase price to be paid for any Option Securities shall be
the same price per share as the price per share for the Firm Securities set

be exercised as to all or any part of the Option Securities from time to time
within 30 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 Company and the Selling Securityholder setting
forth the aggregate number of Option Securities as to which the several
Underwriters are then exercising the options 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 the options and,
in any event, shall not be earlier than the Firm Closing Date.  The





                                      -11-

time and date set forth in such notice, or such other time on such other date
as the Representatives, the Company and the Selling Securityholder may agree
upon or as the Representatives may determine pursuant to Section 9 hereof, is
herein called the "Option Closing Date" with respect to such Option Securities.
Upon exercise of the options as provided herein, the Company and the Selling
Securityholder shall become obligated to sell to each of the several
Underwriters, and, subject to the terms and conditions herein set forth, each
of the Underwriters (severally and not jointly) shall become obligated to
purchase from the Company and the Selling Securityholder, the same percentage
of the total number of the Option Securities as to which the several
Underwriters are then exercising the options as such Underwriter is obligated
to purchase of the aggregate number of Firm Securities, as adjusted by the
Representatives in such manner as they deem advisable to avoid fractional
shares.  If the options are 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 the Selling Securityholder 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 the Selling Securityholder, as the case may be.
Furthermore, in the event that the Underwriters wire funds to the Company or
the Selling Securityholder prior to the completion of the closing of a purchase
of Securities, the Company and the Selling Securityholder hereby acknowledge
that until the Underwriters execute and deliver a receipt for the Securities,
by facsimile or otherwise, neither the Company nor the Selling Securityholder
will 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 the Selling
Securityholder, as the case may be, to the Underwriters on the same day the
wired funds were received by the Company or the Selling Securityholder, the
Company and the Selling Securityholder, as the case may be, agree 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 Securityholder.

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

         (i)     The Company will use its best efforts to cause the
Registration Statement, if not effective at the time of execution of this
Agreement, and any amendments thereto to become effective as promptly as
possible.  If required, the Company will file the Prospectus or any Term Sheet
that constitutes a part thereof





                                      -12-
<PAGE>   13
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 (A) 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 (B) will not file with the
Commission the Prospectus, Term Sheet or the amendment referred to in the
second sentence of Section 2(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 distribution of the
Securities by the several Underwriters, and will use its best efforts to cause
any such amendment to the Registration Statement to be declared effective by
the Commission as promptly as possible.  The Company will advise the
Representatives, promptly after receiving notice thereof, of the time when the
Registration Statement or any amendment thereto has been filed or declared
effective or the Prospectus or any amendment or supplement thereto has been
filed and will provide evidence satisfactory to the Representatives of each
such filing or effectiveness.

         (ii)    The Company will advise the Representatives, promptly after
receiving notice or obtaining knowledge thereof, of (A) the issuance by the
Commission of any stop order suspending the effectiveness of the 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, (B) the suspension of the qualification of the Securities for offering
or sale in any jurisdiction, (C) the institution, threatening or contemplation
of any proceeding for any such purpose or (D) 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.

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

         (iv)    If, at any time prior to the later of (A) the final date when
a prospectus relating to the Securities is required to be delivered under the
Act or (B) the Option Closing Date, any event occurs as a result of which the
Prospectus, as then amended or supplemented, would include any untrue statement
of a material fact or omit to state a material fact necessary in order to make
the statements therein, in the light of the circumstances under which they were
made, not misleading, or if for any other reason it is necessary at any time to
amend or supplement the Prospectus to comply with the Act 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.





                                      -13-
<PAGE>   14
         (v)     The Company will, without charge, provide (A) to the
Representatives and to counsel for the Underwriters a conformed copy of the
Original Registration Statement 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, (B) to each other Underwriter, a conformed copy of such
registration statement or any Rule 462(b) Registration Statement and each
amendment thereto (in each case without exhibits thereto) and (C) so long as a
prospectus relating to the Securities is required to be delivered under the
Act, as many copies of each Preliminary Prospectus or the Prospectus or any
amendment or supplement thereto as the Representatives may reasonably request;
without limiting the application of clause (C) of this sentence, the Company,
not later than (1) 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 (2) 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.

         (vi)    The Company, as soon as practicable, will make generally
available to its securityholders 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.

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

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 120 days after the date hereof, except pursuant to this
Agreement and except for (A) grants of employee stock options under the
Company's 1995 Employee Stock Option Plan, grants of director stock options
under the Company's Director Stock Option Plan (and sales to such employees or
directors pursuant to such options), (B) sales to employees under the Company's
Employee Stock Purchase Plan or Annual Leave Stock Plan and (C) sales of shares
to Nomura Holding America, Inc. issuable upon exercise of warrants issued in
connection with a certain Note and Warrant Purchase Agreement dated as of
February 16, 1996.

         (ix)    The Company will not, directly or indirectly, (A) 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 (B) (1) sell, bid for, purchase, or pay anyone any
compensation for soliciting purchases of, the Securities or (2) 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
Securityholder under this Agreement).

         (x)     The Company will obtain the agreements described in Section
7(h) hereof prior to the Firm Closing Date.

         (xi)    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





                                      -14-
<PAGE>   15
Company shall occur as a result of which in your opinion the market price of
the Common Stock has been or is likely to be materially affected (regardless of
whether such rumor, publication or event necessitates a supplement to or
amendment of the Prospectus), the Company will, after notice from you advising
the Company to the effect set forth above, forthwith prepare, consult with you
concerning the substance of, and disseminate a press release or other public
statement, reasonably satisfactory to you, responding to or commenting on such
rumor, publication or event.

         (xii)   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

Securities remain included for quotation on the Nasdaq National Market
following the Firm Closing Date.

(b)      The Selling Securityholder covenants and agrees with each of the
Underwriters that:

         (i)     The Selling Securityholder will not, directly or indirectly,
(A) 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 Firm Securities or (B) (1) sell, bid for, purchase, or pay
anyone any compensation for soliciting purchases of, the Firm Securities or (2)

         (ii)    The Selling Securityholder 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, grant
any option to purchase or otherwise sell or dispose (or announce any offer,
sale, offer of sale, contract of sale, grant of any option to purchase or other
sale or disposition) of any Securities legally or beneficially owned by the
Selling Securityholder or any securities convertible into, or exchangeable or
exercisable for, Securities for a period of 120 days after the date hereof.

         (iii)   The Selling Securityholder will pay all Federal and other
taxes, if any on the transfer or sale of the Securities being sold by the

         6.      Expenses.  The Company will pay all costs and expenses

experts or advisors retained by the Company, (iv) preparation, issuance and

advertising relating to the offering of the Securities (other than advertising
specifically approved by the Representatives in the Wall Street Journal,
National Edition, to be paid for by the Underwriters).  If the sale of the
Securities provided for herein is not consummated because any condition to the
obligations of the Underwriters set forth in Section 7 hereof is not satisfied,
because this Agreement is terminated pursuant to Section 11 hereof or because
of any failure, refusal or inability on the part of the Company to perform all
obligations and satisfy all conditions on its part to be performed or satisfied
hereunder other than by reason of a default by any of the Underwriters, the
Company will reimburse the Underwriters severally upon demand for all
out-of-pocket expenses (including counsel fees and disbursements) that shall

the Securities.  The Company shall not in any event be liable to any of the
Underwriters for the loss of anticipated profits from the transactions covered

         or any of the Subsidiaries is a party or by which the Company or any
         of the Subsidiaries or any of their respective properties are bound,
         or the charter documents or by-laws of the Company or any of the
         Subsidiaries, or any statute or any judgment, decree, order, rule or

         Commission; and

         into this Agreement and the Custody Agreement and Power-of-Attorney
         and to sell, transfer and deliver the Securities being sold by the
         Selling Securityholder hereunder in the manner provided in this
         Agreement and to perform his obligations under the Custody Agreement
         and Power of Attorney; this Agreement and the Custody Agreement and
         Power-of-Attorney have been duly executed and delivered by the Selling
         Securityholder; assuming due authorization, execution and delivery by
         the Custodian, the Custody Agreement and Power-of-Attorney are the
         legal, valid, binding and enforceable instruments of the Selling
         Securityholder, subject to applicable bankruptcy, insolvency and
         similar laws affecting





                                      -18-
<PAGE>   19
         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);

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

                 (xiv)    the sale of the Securities to the Underwriters by the
         Selling Securityholder pursuant to this Agreement, the compliance by
         the Selling Securityholder with the other provisions of this
         Agreement, the Custody Agreement and Power of Attorney, 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 and such as may be required under state securities
         or blue sky laws, or (B) conflict with or result in a breach or
         violation of any of the terms and provisions of, or constitute a
         default under any indenture, mortgage, deed of trust, lease or other
         agreement or instrument to which the Selling Securityholder is a party
         or by which the Selling Securityholder or any of the Selling
         Securityholder's properties are bound, or any statute or any judgment,
         decree, order, rule or regulation of any court or other governmental
         authority or any arbitrator applicable to the Selling Securityholder.

         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.  In rendering
any such opinion, such counsel may rely, as to matters of fact, to the extent
such counsel deems proper, on certificates of responsible officers of the
Company and public officials.  References to the Registration Statement and the
Prospectus in this paragraph (b) shall include any amendment or supplement
thereto at the date of such opinion.

         (c)     The Representatives shall have received an opinion, dated the
Firm Closing Date, of Deborah Fox, Esq., General Counsel of the Company, to the
effect that:

                 (i) no default exists, and no event has occurred which, with
         notice or lapse of time or both, would constitute a default in the due
         performance and observance of any term, covenant or condition of any
         indenture, mortgage, deed of trust, lease or other agreement or
         instrument to which the Company or any of the Subsidiaries is a party
         or by which the Company or any of the Subsidiaries or any of their
         respective properties is bound or may be affected in any material
         adverse respect with regard to property, business or operations of the
         Company and the Subsidiaries;

                 (ii)     The Company and each of the Subsidiaries have good
         and marketable title in fee simple to all items of real property and
         marketable title to all personal property owned by each of them, in
         each case free and clear of any security interests, liens,
         encumbrances, equities, claims and other defects, except such as do
         not materially and adversely affect the value of such property and do
         not interfere with the use made or proposed to be made of such
         property by the Company or such Subsidiary, and any real property and
         buildings held under lease by the Company or any such Subsidiary are
         held under valid, subsisting and enforceable leases, with such
         exceptions as are not material and do not interfere with the use made
         or proposed to be made of such property and buildings by the Company
         or such Subsidiary, in each case except as described in or
         contemplated

recent Preliminary Prospectus);

                 (iii)    The Company and the Subsidiaries own or possess, or

         applications, trademarks, service marks, trade names, licenses,
         copyrights and proprietary or other confidential information currently
         employed by them in connection with their respective businesses, and
         neither the Company nor any such Subsidiary has received any notice of
         infringement of or conflict with asserted rights of any third party
         with respect to any of the foregoing which, singly or in the
         aggregate, if the subject of an unfavorable decision, ruling or
         finding, would result in a material adverse change in the condition
         (financial or otherwise), business prospects, net worth or results of
         operations of the Company and the Subsidiaries, except as described in
         or contemplated by the Prospectus (or, if the Prospectus is not in
         existence, the most recent Preliminary Prospectus);

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

                 (v)      No Subsidiary of the Company is currently prohibited,
         directly or indirectly, from paying any dividends to the Company, from
         making any other distribution on such Subsidiary's capital stock, from
         repaying to the Company any loans or advances to such Subsidiary from
         the Company or from transferring any of such Subsidiary's property or
         assets to the Company or any other Subsidiary of the Company;

                 (vi)     The Company and the Subsidiaries possess all
         certificates, authorizations and permits issued by the appropriate
         federal, state or foreign regulatory authorities necessary to conduct
         their respective businesses, and neither the Company nor any such
         Subsidiary has received any notice of proceedings relating to the
         revocation or modification of any such certificate, authorization or
         permit which, singly or in the aggregate, if the subject of an
         unfavorable decision, ruling or finding, would result in a material
         adverse change in the condition (financial or otherwise), business
         prospects, net worth or results of operations of the Company and the
         Subsidiaries, except as described in or contemplated by the Prospectus
         (or, if the Prospectus is not in existence, the most recent
         Preliminary Prospectus);

                 (vii)    The Company has filed all foreign, federal, state and
         local tax returns that are required to be filed or has requested
         extensions thereof (except in any case in which the failure so to file
         would not have a material adverse effect on the Company and the
         Subsidiaries) and has paid all taxes required to be paid by it and any
         other assessment, fine or penalty levied against it, to the extent
         that any of the foregoing is due and payable, except for any such
         assessment, fine or penalty that is currently being contested in good
         faith or as described in or contemplated by the Prospectus (or, if the
         Prospectus is not in existence, the most recent Preliminary
         Prospectus);

                 (viii)   Neither the Company nor any of the Subsidiaries is in
         violation of any federal or

         state law or regulation relating to occupational safety and health or
         to the storage, handling or transportation of hazardous or toxic
         materials and the Company and the Subsidiaries have received all
         permits, licenses or other approvals required of them under applicable
         federal and state occupational safety and health and environmental
         laws and regulations to conduct their respective businesses, and the
         Company and each such Subsidiary is in compliance with all terms and
         conditions of any such permit, license or approval, except any such
         violation of law or regulation, failure to receive required permits,
         licenses or other approvals or failure to comply with the terms and
         conditions of such permits, licenses or approvals which would not,
         singly or in the aggregate, result in a material adverse change in the
         condition (financial or otherwise), business prospects, net worth or
         results of operations of the Company and the Subsidiaries, except as
         described in or contemplated by the Prospectus (or, if the Prospectus
         is not in existence, the most recent Preliminary Prospectus);

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

         Deborah Fox, Esq. shall also state that she has 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.  In rendering
any such opinion, Deborah Fox, Esq. may rely, as to matters of fact, to the
extent such counsel deems proper, on certificates of responsible officers of
the Company and public officials.  References to the Registration Statement and
the Prospectus in this paragraph (c) shall include any amendment or supplement
thereto at the date of such opinion.

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

         (e)     The Representatives shall have received from KPMG Peat
Marwick, LLP 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 and pro forma financial data read 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





                                      -21-
<PAGE>   22
condensed financial statements of the Company and its consolidated
subsidiaries, a reading of the unaudited amounts for sales, net revenues and
total and per share amounts of net income for the six months ending September
30, 1995 and 1996 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 shareholders, 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 condensed financial statements
         of the Company and its consolidated subsidiaries included in the
         Registration Statement and the Prospectus do not comply in form in all
         material respects with the applicable accounting requirements of the
         Act 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 sales, net revenues 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 not current assets or stockholders'
         equity of the Company and its consolidated subsidiaries, in each case
         compared with amounts shown on the September 30, 1996 unaudited
         consolidated balance sheet included in the Registration Statement and
         the Prospectus, or for the period from October 1, 1996 to such
         specified date there were any decreases, as compared with the
         corresponding period beginning October 1, 1995, in sales, net
         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 and in the exhibits 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 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

         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;

         Registration Statement or any amendment thereto has been issued, and
         no proceedings for that purpose are instituted or, to the best of the
         Company's knowledge, threatened or contemplated by the Commission; and

                 (iii)    subsequent to the respective dates as of which

         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 the Subsidiaries, except in each case as described in or
         contemplated by the Prospectus (exclusive of any amendment or
         supplement thereto).

         (g)     The Representatives shall have received a certificate signed
by or on behalf of the Selling Securityholder, dated the Closing Date, to the
effect that:

                 (i)      the representations and warranties of the Selling
         Securityholder in this Agreement are true and correct as if made on

         Prospectus or any amendment or supplement thereto in reliance upon and
         in conformity with written information furnished to the Company by the

         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, tape recordings,

         and will reimburse, as incurred, each Underwriter and each such
controlling person for any legal or other expenses reasonably incurred by such
Underwriter or such controlling person in connection with investigating,
defending against or appearing as a third-party witness in connection with any
such loss, claim, damage, liability or action; provided, however, that the
Company and the Selling Securityholder 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.  This indemnity agreement will be
in addition to any liability which the Company and the Selling Securityholder
may otherwise have.  Neither the Company nor the Selling Securityholder will,
without the prior written consent of the Underwriter or Underwriters
purchasing, in the aggregate, more than fifty percent (50%) of the Securities,
settle or compromise or consent to the entry of any judgment in any pending or
threatened claim, action, suit or proceeding in respect of which
indemnification may be sought hereunder (whether or not any such Underwriter or
any person who controls any such Underwriter within the meaning of Section 15
of the Act or Section 20 of the Exchange Act is a party to such claim, action,
suit or proceeding), unless such settlement, compromise or consent includes an
unconditional release of all of the Underwriters and such controlling persons
from all liability arising out of such claim, action, suit or proceeding.

         (b)     Each Underwriter, severally and not jointly, will indemnify
and hold harmless the Company, each of its directors, each of its officers who
signed the Registration Statement, the Selling Securityholder, and each person,
if any, who controls the Company 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, officer, the Selling
Securityholder or any 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 (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 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, the Selling Securityholder, or any such
director, officer or 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
such Underwriter may otherwise have.

         (c) Promptly after receipt by an indemnified party under this Section
8 of notice of the commencement of any action, such indemnified party will, if
a claim in respect thereof is to be made against





                                      -25-
<PAGE>   26
the indemnifying party under this Section 8, notify the indemnifying party of
the commencement thereof; but the omission so to notify the indemnifying party
will not relieve it from any liability which it may have to any indemnified
party otherwise than under this Section 8. In case any such action is brought
against any indemnified party, and it notifies the indemnifying party of the
commencement thereof, the indemnifying party will be entitled to participate
therein and, to the extent that it may wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with
counsel satisfactory to such indemnified party; provided, however, that if the
defendants in any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
that there may be one or more legal defenses available to it and/or other
indemnified parties which are different from or additional to those available
to the indemnifying party, the indemnifying party shall not have the right to
direct the defense of such action on behalf of such indemnified party or
parties and such indemnified party or parties shall have the right to select
separate counsel to defend such action on behalf of such indemnified party or
parties.  After notice from the indemnifying party to such indemnified party of
its election so to assume the defense thereof and approval by such indemnified
party of counsel appointed to defend such action, the indemnifying party will
not be liable to such indemnified party under this Section 8 for any legal or
other expenses, other than reasonable costs of investigation, subsequently
incurred by such indemnified party in connection with the defense thereof,
unless (i) the indemnified party shall have employed separate counsel in
accordance with the proviso to the next preceding sentence (it being
understood, however, that in connection with such action the indemnifying party
shall not be liable for the expenses of more than one separate counsel (in
addition to local counsel) in any one action or separate but substantially
similar actions in the same jurisdiction arising out of the same general
allegations or circumstances, designated by the Representatives in the case of
paragraph (a) of this Section 8, representing the indemnified parties under
such paragraph (a) who are parties to such action or actions) or (ii) the
indemnifying party does not promptly retain counsel satisfactory to the
indemnified party or (iii) the indemnifying party has authorized the employment
of counsel for the indemnified party at the expense of the indemnifying party.
After such notice from the indemnifying party to such indemnified party, the
indemnifying party will not be liable for the costs and expenses of any
settlement of such action effected by such indemnified party without the
consent of the indemnifying party.

         (d)     In circumstances in which the indemnity agreement provided for
in the preceding paragraphs of this Section 8 is unavailable or insufficient,
for any reason, to hold harmless an indemnified party in respect of any losses,
claims, damages or liabilities (or actions in respect thereof), each
indemnifying party, in order to provide for just and equitable contribution,
shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages or liabilities (or actions in respect
thereof) in such proportion as is appropriate to reflect (i) the relative
benefits received by the indemnifying party or parties on the one hand and the
indemnified party on the other from the offering of the Securities or (ii) if
the allocation provided by the foregoing clause (i) is not permitted by
applicable law, not only such relative benefits but also the relative fault of
the indemnifying party or parties on the one hand and the indemnified party on
the other in connection with the statements or omissions or alleged statements
or omissions that resulted in such losses, claims, damages or liabilities (or
actions in respect thereof), as well as any other relevant equitable
considerations.  The relative benefits received by the Company and the Selling
Securityholder on the one hand and the Underwriters on the other shall be
deemed to be in the same proportion as the total proceeds from the offering
(before deducting expenses) received by the Company and the Selling
Securityholder 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 Securityholder 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.





                                      -26-
<PAGE>   27
The Company, the Selling Securityholder 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 (d).  Notwithstanding any other provision of this paragraph (d), 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 II (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 (d), 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 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.

         (e)     The aggregate liability of the Selling Securityholder under
all provisions of this Agreement shall not exceed the amount equal to the
aggregate proceeds received by the Selling Securityholder for the Securities
sold by the Selling Securityholder 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 Securityholder and the several Underwriters set





                                      -27-
<PAGE>   28
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 Securityholder, 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 given prior to the Firm Closing
Date or the related Option Closing Date, respectively, in the event that either
the Company or the Selling Securityholder shall have failed, refused or been
unable to perform all obligations and satisfy all conditions on its part to be
performed or satisfied hereunder at or prior thereto or, if at or prior to the
Firm Closing Date or such Option Closing Date, respectively,

                 (i)      the Company or any of its subsidiaries shall have, in
         the sole judgment of the Representatives, sustained any material loss
         or interference with their 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 Nasdaq National Market or 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 such exchange or market system;

                 (iii)    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 for the
purposes of Sections 2(b) and 8 hereof.  The Underwriters confirm that such
statements (to such extent) are correct.

         14.     Successors.  This Agreement shall inure to the benefit of and
shall be binding upon the several Underwriters, the Company, the Selling
Securityholder, and their respective successors and legal representatives, and
nothing expressed or mentioned in this Agreement is intended or shall be
construed to give any other person any legal or equitable right, remedy or
claim under or in respect of this Agreement, or any provisions herein
contained, this Agreement and all conditions and provisions hereof being
intended to be and being for the sole and exclusive benefit of such persons and
for the benefit of no other person except that (i) the indemnities of the
Company and the Selling Securityholder contained in Section 8 of this Agreement
shall also be for the benefit of any person or persons who control any
Underwriter within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act and (ii) the indemnities of the Underwriters contained in Section
8 of this Agreement shall also be for the benefit of the directors of the
Company, the officers of the Company who have signed the Registration
Statement, the Selling Securityholder and any person or persons who control the
Company within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act.  No purchaser of Securities from any Underwriter shall be deemed
a successor because of such purchase.

         15.     Applicable Law.  The validity and interpretation of this
Agreement, and the terms and conditions set forth herein, shall be governed by
and construed in accordance with the laws of the State of New York, without
giving effect to any provisions relating to conflicts of laws.

         16.     Consent to Jurisdiction and Service of Process.  All judicial
proceedings arising out of or relating to this Agreement may be brought in any
state or federal court of competent jurisdiction in the State of New York, and
by execution and delivery of this Agreement, the Selling Securityholder accepts
for itself and in connection with its properties, generally and
unconditionally, the nonexclusive jurisdiction of the aforesaid courts and
waives any defense of forum non conveniens and irrevocably agrees to be bound
by any judgment rendered thereby in connection with this Agreement.  The
Selling Securityholder designates and appoints __________________, and such
other persons as may hereafter be selected by the Selling Securityholder
irrevocably agreeing in writing to so serve, as its agent to receive on its
behalf service of all process in any such proceedings in any such court, such
service being hereby acknowledged by the Selling Securityholder to be effective
and binding service in every respect.  A copy of any such process so served
shall be mailed by registered mail to the Selling Securityholder at its address
provided in Section 13 hereof; provided, however, that, unless otherwise
provided by applicable law, any failure to mail such copy shall not affect the
validity of service of such process.  If any agent appointed by the Selling
Securityholder refuses to accept service, the Selling Securityholder hereby
agrees that service of process sufficient for personal jurisdiction in any
action against the Selling Securityholder in the State of New York may be made
by registered or certified mail, return receipt requested, to the Selling
Securityholder at its address provided in Section 13 hereof, and the Selling
Securityholder hereby acknowledges that such service shall be effective and
binding in every respect.  Nothing herein shall affect the right to serve
process in any other manner permitted by law or shall limit the right of any
Underwriter to bring proceedings against the Selling Securityholder in the
courts of any other jurisdiction.

         17.     Counterparts.  This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

                                                                OCTOBER 15, 1996

                                   BTG, INC.
                   NON-EMPLOYEE DIRECTOR STOCK PURCHASE PLAN

         The Board of Directors of BTG, Inc. (the "Company") has adopted this
Non-Employee Director Stock Purchase Plan (the "Plan") to enable individuals
who serve as directors of the Company and who are not employees of the Company
("Non-Employee Directors"), through the retention by the Company of fees to be
paid to such Non-Employee Directors for services as directors, to purchase
shares of the Company's Common Stock, no par value per share (the "Common
Stock").  The purpose of the Plan is to benefit the Company by increasing the
Non-Employee Directors' proprietary interest in the Company's growth and
success and enabling the Company to continue to attract highly qualified
persons to serve as Non-Employee Directors.  The provisions of the Plan are set
forth below:

1.       SHARES SUBJECT TO THE PLAN.

         Subject to adjustment as provided in Section 21 below, an aggregate of
100,000 shares of Common Stock will be made available for purchase by
participants under the Plan.  The shares issuable under the Plan may, in the
discretion of the Board of Directors of the Company (the "Board"), be either
authorized but unissued shares or treasury shares.

2.       ADMINISTRATION.

         The Plan shall be administered by the Board.  The Board's actions
under the Plan shall be limited to taking all actions authorized by this Plan
or otherwise reasonably necessary to effect the purposes hereof.





<PAGE>   2
3.       INTERPRETATION.

          Subject to the express provisions of the Plan, the Board shall have
authority to interpret the Plan, to prescribe, amend and rescind rules relating
to it, and to make all other determinations necessary or advisable in
administering the Plan, all of which determinations will be final and binding
upon all persons.

4.       ELIGIBILITY TO PARTICIPATE.

         The only persons eligible to participate in the Plan shall be
directors of the Company who are not employees of the Company.

5.       PARTICIPATION IN THE PLAN.

         A Non-Employee Director may become a participant in the Plan by
completing an election to participate in the Plan on an authorization form
provided by the Company and submitting that form to the Secretary of the
Company.  The form will authorize the Company to retain a whole percentage
amount of not less than one percent (the "Stated Percentage") of the
Non-Employee Director's eligible fees (as defined in Section 6 below) and
authorize the purchase of shares of Common Stock for the Non-Employee
Director's account in accordance with the terms of the Plan.  Enrollment will
become effective upon the first day of the first Accumulation Period (as
defined in Section 7 below) that commences after the Company's receipt of the
form.

6.       FEE RETENTION.

         From and after the effective date of a Non-Employee Director's
enrollment in the Plan (as provided in Section 5 above), the Non-Employee
Director shall elect to have an amount equal to the Stated Percentage of
eligible fees payable to such Non-





                                       2
<PAGE>   3




Employee Director on each Fee Payment Date (as defined below) retained by the
Company.  For purposes of this Plan, "eligible fees" include all fees which the
Non-Employee Director is entitled to receive from the Company for his or her
service as a director, including annual director fees, per meeting director
fees and per meeting committee fees.  The fee retentions will be credited to
the Non-Employee Director's account under the Plan.  A Non-Employee Director
may not contribute amounts to purchase Common Stock under the Plan other than
through fee retentions.  As used herein, the term "Fee Payment Date" means, for
each Non-Employee Director, each date on which an eligible fee is payable to
such Non-Employee Director.  A Non-Employee Director may not during any
Accumulation Period change his or her Stated Percentage of eligible fees to be
retained for that Accumulation Period, nor may a Non-Employee Director withdraw
any contributed funds other than by terminating participation in accordance
with Section 15 below.

7.       ACCUMULATION PERIODS.

         The first Accumulation Period under the Plan shall commence on October
16, 1996 and end on September 30, 1997 (the "Initial Accumulation Period").
Subsequent Accumulation Periods will be 12-month periods beginning on October 1
of each year and ending on September 30 of the following year.

8.       PURCHASE PRICE.

The purchase price of each share of Common Stock (the "Purchase Price") will be
the lesser of the fair market value of the Common Stock (i) on the first
trading day of the Accumulation Period or (ii) on the last trading day of such
Accumulation Period.  For purposes of the Plan, "fair market value" means, if
the Common Stock is listed on an established national or regional stock
exchange, is admitted to quotation on the National Association of Securities
Dealers Automated Quotation System, or is publicly traded in an established
securities market, the closing price of the Common Stock on such exchange or
system or in such market (the highest such closing price if there is more than
one such exchange or market) on such date (or, if





                                       3
<PAGE>   4
there is no such closing price, the mean between the highest bid and lowest
asked prices or between the high and low prices on such date), or, if no sale
of the Common Stock has been made on such day, or the next preceding day on
which any such sale shall have been made.

9.       TIMING OF PURCHASE.

         Unless a participating Non-Employee Director's participation in the
Plan has been terminated as provided in Section 15 below, shares of Common
Stock will be purchased for such Non-Employee Director's account automatically
on the last trading day of each Accumulation Period (except as provided in
Section 15 below).  Shares may not be purchased at any other time under the
Plan.  Effective upon the last trading day of each Accumulation Period, each
participating Non-Employee Director's account will be credited with the number
of shares of Common Stock  which the accumulated funds in such Non-Employee
Director's account at that time will purchase at the Purchase Price.

10.      ISSUANCE OF STOCK CERTIFICATES.

         On the last trading day of the Accumulation Period, a participating
Non-Employee Director will be credited with the number of shares of Common
Stock purchased for his or her account under the Plan during such Period.
Shares purchased under the Plan will be held in the custody of First Union
National Bank as agent (the "Agent").  The Agent may hold the shares purchased
under the Plan in stock certificates in nominee names and may commingle shares
held in its custody in a single account or stock certificate without
identification as to individual participating Non-Employee Director.  A
participating Non-Employee Director may, at any time following his or her
purchase of shares under the Plan, by written notice instruct the Agent to have
all or part of such shares reissued in the





                                       4
<PAGE>   5




participating Non-Employee Director's own name and have the stock certificate
delivered to the Non-Employee Director.

11.      WITHHOLDING OF TAXES.

         To the extent that a participating Non-Employee Director realizes
ordinary income in connection with the Plan (including, without limitation, as
a result of the accrual of fees or the purchase, issuance, sale or other
transfer of shares of Common Stock under the Plan) and the Company is required
to withhold taxes with respect thereto, the Company may withhold amounts needed
to cover such taxes from any payments otherwise due and owing to the
Non-Employee Director or from shares that would otherwise be credited or issued
to the Non-Employee Director hereunder.

12.      ACCOUNT STATEMENTS.

         The Company will cause the Agent to deliver to each participating
Non-Employee Director a statement for each Accumulation Period during which the
Non-Employee Director purchases Common Stock under the Plan reflecting the
amount of fee retentions accumulated during the Accumulation Period, the number
of shares, including any fractional share interest, purchased for the
Non-Employee Director's account, the price per share of the shares purchased
for the Non-Employee Director's account, and the number of shares, including
any fractional share interest, held for the Non-Employee Director's account at
the end of the Accumulation Period.

13.      PARTICIPATION ADJUSTMENT.

         If in any Accumulation Period the number of unsold shares that may be
made available for purchase under the Plan pursuant to Section 1 above is
insufficient to





                                       5
<PAGE>   6
permit exercise of all rights deemed exercised by all participating
Non-Employee Directors pursuant to Section 9 above, a participation adjustment
will be made, and the number of shares purchasable by all participating
Non-Employee Directors will be reduced proportionately.  Any funds then
remaining in a participating Non-Employee Director's account after such
exercise will be promptly refunded to the Non-Employee Director.

14.      TERMINATION OF SERVICE AS A DIRECTOR OTHER THAN FOR CAUSE.

         If the Non-Employee Director ceases to be a director other than due to
a termination for cause, the amount then credited to such director's account
will continue to be credited with interest and the director's option to
purchase shall be reduced to the number of shares which may be purchased, as of
the last day of the Accumulation Period, with the amount then credited to the
Non-Employee Director's account.

15.      TERMINATION OF SERVICE AS A DIRECTOR FOR CAUSE; TERMINATION OF PLAN.

         If (i) the Board elects to terminate the Plan as provided in Section
20 below, or (ii) the Non-Employee Director is terminated for cause, the
participating Non-Employee Director will be refunded all monies in his or her
account (including interest).  As soon as practicable following the effective
date of termination of a Non-Employee Director's participation in the Plan
pursuant to this Section 15, the Company will deliver to the Non-Employee
Director a check representing the amount (including interest) in the
Non-Employee Director's account and a stock certificate representing the number
of whole shares held in the Non-Employee Director's account.





                                       6

16.      ASSIGNMENT.

         No participating Non-Employee Director may assign his or her rights to
purchase shares of Common Stock under the Plan, whether voluntarily, by
operation of law or otherwise.  Any payment of cash or issuance of shares of
Common Stock under the Plan may be made only to the participating Non-Employee
Director (or, in the event of the Non-Employee Director's death, to the
Non-Employee Director's estate).  Once a stock certificate has been issued to
the Non-Employee Director or for his or her account, such certificate may be
assigned the same as any other stock certificate.

17.      APPLICATION OF FUNDS.

         All funds retained by the Company under the Plan may be used for any
corporate purpose until applied to the purchase of Common Stock and/or refunded
to participating Non-Employee Directors.  Participating Non-Employee Directors'
accounts will not be segregated.  Interest will not be paid on funds held by
the Company pursuant to the Plan.

18.      NO RIGHT TO CONTINUED MEMBERSHIP ON THE BOARD.

         Neither the Plan nor any right to purchase Common Stock under the Plan
confers upon any Non-Employee Director any right to continued membership on the
Board, nor will a Non-Employee Director's participation in the Plan create any
obligation on the part of the Board to nominate any director for re-election by
the Company's stockholders.

19.      AMENDMENT OF PLAN.

         Unless otherwise required by law, the Board may, at any time, amend
the Plan in any respect; provided, however, that without approval of the
stockholders of the Company no amendment shall be made impairing the vested
rights of participating Non-Employee Directors.

20.      EFFECTIVE DATE; TERM AND TERMINATION OF THE PLAN.

         The Plan shall be effective as of the date of adoption by the Board,
which date is set forth below, subject to approval of the Plan by a majority of
the votes present and entitled to vote at a duly held meeting of the
shareholders of the Company at which a quorum representing a majority of all
outstanding voting stock is present, either in person or by proxy; provided,
however, that upon approval of the Plan by the shareholders of the Company as
set forth above, all rights to purchase shares granted under the Plan on or
after the effective date shall be fully effective as if the shareholders of the
Company had approved the Plan on the effective date.  If the shareholders fail
to approve the Plan on or before one year after the effective date, the Plan
shall terminate, any rights to purchase shares granted hereunder shall be null
and void and of no effect, and all contributed funds shall be refunded to
participating Non-Employee Directors.  The Board may terminate the Plan at any
time and for any reason or for no reason, provided that such termination shall
not impair any rights of participating Non-Employee Directors that have vested
at the time of termination.  In any event, the Plan shall, without further
action of the Board, terminate five (5) years after the date of adoption of the
Plan by the Board or, if earlier, at such time as all shares of Common Stock
that may be made available for purchase under the Plan pursuant to Section 1
above have been issued.

21.      EFFECT OF CHANGES IN CAPITALIZATION.

         (a)     CHANGES IN STOCK.

         If the number of outstanding shares of Common Stock is increased or
decreased or the shares of Common Stock are changed into or exchanged for a
different number or kind of shares or other securities of the Company by reason
of any recapitalization, reclassification, stock split, reverse split,
combination of shares, exchange of shares, stock dividend, or other
distribution payable in capital stock, or other increase or decrease in such
shares effected without receipt of consideration by the Company occurring after
the effective date of the Plan, the number and kinds of shares that may be
purchased under the Plan shall be adjusted proportionately and accordingly by
the Company.  In addition, the number and kind of shares for which rights are
outstanding shall be similarly adjusted so that the proportionate interest of a
participating Non-Employee Director immediately following such event shall, to
the extent practicable, be the same as immediately prior to such event.  Any
such adjustment in outstanding rights shall not change the aggregate Purchase
Price payable by a participating Non-Employee Director with respect to shares
subject to such rights, but shall include a corresponding proportionate
adjustment in the Purchase Price per share.

         (b)     REORGANIZATION IN WHICH THE COMPANY IS THE SURVIVING
                 CORPORATION.

         Subject to Subsection (c) of this Section 21, if the Company shall be
the surviving corporation in any reorganization, merger or consolidation of the
Company with one or more other corporations, all outstanding rights under the
Plan shall pertain to and apply to the securities to which a holder of the
number of shares of Common Stock subject to such rights would have been
entitled





                                       9
<PAGE>   10
immediately following such reorganization, merger or consolidation, with a
corresponding proportionate adjustment of the Purchase Price per share so that
the aggregate Purchase Price thereafter shall be the same as the aggregate
Purchase Price of the shares subject to such rights immediately prior to such
reorganization, merger or consolidation.

         (c)     REORGANIZATION IN WHICH THE COMPANY IS NOT THE
                 SURVIVING CORPORATION OR SALE OF ASSETS OR STOCK.

         Upon any dissolution or liquidation of the Company, or upon a merger,
consolidation or reorganization of the Company with one or more other
corporations in which the Company is not the surviving corporation, or upon a
sale of all or substantially all of the assets of the Company to another
corporation, or upon any transaction (including, without limitation, a merger
or reorganization in which the Company is the surviving corporation) approved
by the Board that results in any person or entity owning more than 50 percent
of the combined voting power of all classes of stock of the Company, the Plan
and all rights outstanding hereunder shall terminate, except to the extent
provision is made in writing in connection with such transaction for the
continuation of the Plan and/or the assumption of the rights theretofore
granted, or for the substitution for such rights of new rights covering the
stock of a successor corporation, or a parent or subsidiary thereof, with
appropriate adjustments as to the number and kinds of shares and exercise
prices, in which event the Plan and rights theretofore granted shall continue
in the manner and under the terms so provided.  In the event of any such
termination of the Plan, the Accumulation Period shall be deemed to have ended
on the last trading day prior to such termination, and in accordance with
Section 9 above the rights of each participating Non-Employee Director then
outstanding shall be deemed to be automatically exercised on such last trading
day.  The Board shall





                                       10
<PAGE>   11




send written notice of an event that will result in such a termination to all
participating Non-Employee Directors not later than the time at which the
Company gives notice thereof to its stockholders.

         (d)     ADJUSTMENTS.

         Adjustments under this Section 21 related to stock or securities of
the Company shall be made by the Committee, whose determination in that respect
shall be final, binding, and conclusive.  No fractional shares of Common Stock
or units of other securities shall be issued pursuant to any such adjustment,
and any fractions resulting from any such adjustment shall be eliminated in
each case by rounding downward to the nearest whole share or unit.

         (e)     NO LIMITATIONS ON COMPANY.

         The grant of a right pursuant to the Plan shall not affect or limit in
any way the right or power of the Company to make adjustments,
reclassifications, reorganizations or changes of its capital or business
structure or to merge, consolidate, dissolve or liquidate, or to sell or
transfer all or any part of its business or assets.

22.      GOVERNMENTAL REGULATION.

         The Company's obligation to issue, sell and deliver shares of Common
Stock pursuant to the Plan is subject to such approval of any governmental
authority and any national securities exchange or other market quotation system
as may be required in connection with the authorization, issuance or sale of
such shares.

23.      STOCKHOLDER RIGHTS.

         Any dividends paid on shares held for a participating Non-Employee
Director's account will be transmitted to the Non-Employee Director.  The
Company will deliver to each participating Non-Employee Director who purchases
shares of Common Stock under the Plan, as promptly as practicable by mail or
otherwise, all notices of meetings, proxy statements, proxies and other
materials distributed by the Company to its stockholders.  Any shares of Common
Stock held for a Non-Employee Director's account will be voted in accordance
with the Non-Employee Director's duly delivered and signed proxy instructions.
There will be no charge to participating Non-Employee Directors in connection
with such notices, proxies and other materials.

24.      PAYMENT OF PLAN EXPENSES.

         The Company will bear all costs of administering and carrying out the
Plan.

25.      RULE 16B-3.

         Transactions under this Plan are intended to comply with all
applicable conditions of Rule 16b-3 or any successor provision under the
Securities Exchange Act of 1934.  If any provision of the Plan or action by the
Board fails to so comply, it shall be deemed null and void to the extent
permitted by law and deemed advisable by the Board.  Moreover, in the event the
Plan does not include a provision required by Rule 16b-3 to be stated herein,
such provision (other than one relating to eligibility requirements, or the
price and amount of awards) shall be deemed automatically to be incorporated by
reference into the Plan.

                 be incurred under the Credit Agreement after March 31, 1997,
                 if the effect of such incurrence is to increase the aggregate

                 pursuant to the Credit Agreement to an amount which is greater
                 than $65,000,000 but not greater than $85,000,000, unless at
                 the time of such incurrence, under the foregoing provisions of
                 this subsection (d), an increase in the maximum aggregate
                 commitment amount of the Indebtedness incurred pursuant to the
