                               PROSPECTUS SUMMARY
 
    The following summary is qualified in its entirety by the more detailed
information and financial statements, including the notes thereto, appearing
elsewhere in this Prospectus. Unless the context otherwise requires, references
herein to the "Company" or "BDM" include BDM International, Inc. and its
subsidiaries. Unless otherwise indicated, all information in this Prospectus
assumes that the Underwriters' over-allotment options are not exercised.
 
                                  THE COMPANY
 
    BDM is a multinational information technology company that operates in three
interrelated markets:
 
    . SYSTEMS AND SOFTWARE INTEGRATION. The Company creates information and
      other computer-based systems that are tailored to specific public and
      private sector client needs. It does so by applying commercial
      off-the-shelf hardware and software, purchased from multiple vendors, to
      user-oriented system solutions with integrated software developed by the
      Company. BDM's expertise includes consolidating computer operations and/or
      migrating from older mainframe-based computer systems to newer, more
      flexible, standardized open systems based on client/server architectures
      linked by local and wide-area networks. Current multi-year contracts in
      this market include development and delivery of client/server as well as
      mainframe-based management information and transaction processing systems,
      real time control systems (such as air traffic control), automated
      distribution systems and computer networks. Systems and Software
      Integration revenue in 1994 was approximately $197 million (26% of total
      revenue) and has grown at a compound annual growth rate of 33% since 1991
      (31% excluding acquisitions).
 
    . COMPUTER AND TECHNICAL SERVICES. The Company provides a broad range of
      scientific, engineering, technical assistance and consulting services
      spanning the complete life-cycle of complex programs. Typical assignments
      involve system concept development, requirements analysis, training and
      systems testing. Specific examples include advanced modeling and
      simulation services to help clients improve planning, testing and
      training; the use of image technology to enhance security and
      intelligence; numerous programs in command, control, communications,
      computers and intelligence to assist the U.S. military services and other
      clients; and environmental remediation and waste management services.
      Through this work, BDM also gains insights into its clients' operations,
      identifies potential cost-effective systems solutions and thereby
      positions itself to capture complex systems and software integration
      opportunities. Computer and Technical Services revenue in 1994 was
      approximately $491 million (63% of total revenue) and has grown at a
      compound annual growth rate of 36% since 1991 (4% excluding acquisitions).
 
    . ENTERPRISE MANAGEMENT AND OPERATIONS. The Company manages and operates
      research and development centers, test facilities and logistics and
      training centers on behalf of its clients. Examples include managing and
      operating the U.S. government's primary petroleum energy research
      facility; various European test facilities for vehicles, aircraft and
      spacecraft; and five Job Corps Centers. These activities, together with
      the Company's capabilities in Systems and Software Integration and
      Computer and Technical Services, enable BDM to provide the full range of
      services that its clients often require. Enterprise Management and
      Operations revenue in 1994 was approximately $86 million (11% of total
      revenue) and has grown at a compound annual growth rate of 71% since 1991
      (24% excluding acquisitions).

BUSINESS STRATEGIES AND STRENGTHS
 
    BDM is pursuing a strategy of growth and diversification through its
decentralized subsidiaries--BDM Federal, BDM Technologies, BDM Europe and
Vinnell--to become a global information technology ("IT") company. Total revenue
has grown from $297 million in 1991 to $774 million in 1994, a compound annual
growth rate of 38% (14% excluding acquisitions). Building on its core
competencies developed over 35 years of serving the U.S. Department of Defense
(the "DOD") and its reputation for high quality professional work, BDM is
transferring its expertise to selected public and private sector clients in
targeted vertical markets. The following chart illustrates how BDM has
implemented its diversification program from 1991 through 1994:

Depicted here is a bar chart displaying substantially the following
information (revenue in thousands):

    The aggregate stated award value of new contracts won by the Company in 1994
exceeded $1 billion for the second consecutive year. No single contract
represented more than 10% of total revenue in 1994. See "Business--Company
Operations" for a description of some of the Company's contracts.
 
    BDM attributes much of its recent performance to the following strategies
and strengths:
 
    EMPHASIS ON INFORMATION TECHNOLOGY SYSTEMS MARKETS. BDM has placed an
emphasis on strengthening its ability to compete in the fast-growing systems and
software integration marketplace, focusing on large multi-year contracts ranging
upward from $50 million. The Company has pursued its information systems
strategy through such actions as the establishment of BDM Technologies, an IT
company focused on commercial and state and local government clients, and the
acquisition of two European companies that possess significant IT systems
capabilities. To enhance the Company's ability to compete in targeted vertical
information systems markets, the Company is developing a common IT strategy,
standardized software methodologies, and a pool of systems professionals who can
be deployed across each of its subsidiaries. The Company believes that its
position and reputation in IT markets are reflected by its dollar-based
competitive win rate of 51% of the Company's bids on contracts awarded in 1994.
 
    EXPANSION INTO TARGETED MARKETS. The Company has successfully transitioned
its expertise gained from work with the DOD into such vertical markets as
environmental/waste management, energy research and development, air traffic
control, work force development and training, education technologies, health and
human services information management, and manufacturing and distribution
automation for civil government and commercial clients. BDM has penetrated the
civil
 
                                       4
<PAGE>
government business through systems development and integration contracts, such
as its Electronic Data Gathering, Analysis and Retrieval ("EDGAR") system for
the SEC, and has built a market position in health and welfare systems for state
governments and education systems for state and local school districts. BDM's
commercial and civil government business (both international and domestic)
increased from $92 million in 1991 to $336 million in 1994, representing
approximately 43% of the Company's 1994 revenue.
 
    GLOBAL DIVERSIFICATION. In 1994, BDM generated more revenue from
international clients ($336 million) than from all sources in 1991 ($297
million). The Company believes that its ability to serve clients on a global
basis is a competitive differentiator in the marketplace. The Company's overseas
presence allows it to project its core competencies into less competitive IT
markets which the Company believes will afford significant growth and margin
expansion opportunities. BDM has expanded vigorously into European and Middle
Eastern markets, aided by two key acquisitions, and has begun marketing in the
Pacific Rim.
 
    FOCUSED ACQUISITION PROGRAM. The Company is experienced in identifying and
consummating acquisitions and subsequently integrating acquired businesses into
existing operations. The Company intends to continue to pursue an acquisition
program, primarily focused on expanding its position in global information
technology markets. The Company will concentrate on identifying acquisition
targets, particularly those focusing on commercial clients, which have strong
existing management teams in place that can be integrated into BDM's
decentralized operating structure within a common overall strategy.

(1) On November 16, 1993, the Company acquired a 45% interest in
    Industrieanlagen-Betriebsgesellschaft mbH ("IABG"), a company formerly owned
    indirectly by the German Government, and entered into an agreement which
    gives the Company voting control of IABG and permits the Company to manage
    IABG's operations. The Company's financial statements consolidate IABG's
    financial position and results of operations and report the remaining
    owners' 55% interest as a minority interest. This acquisition was accounted
    for as a purchase, and the Company's consolidated results of operations
    include IABG from the date of its acquisition through its subsidiary, BDM
    Europe.
 
(2) On March 13, 1992, the Company acquired the outstanding common stock of
    Vinnell Corporation ("Vinnell") for approximately $29.6 million, including
    transaction expenses. This acquisition was accounted for as a purchase, and
    the Company's consolidated results of operations include Vinnell from the
    date of its acquisition.
 
(3) The Company was acquired in an investor and management led buyout on October
    23, 1990. The acquisition was accounted for as a purchase, and $93.5 million
    of indebtedness of the Company related to the buyout was incurred. The
    results of 1991 and 1990 reflect certain one-time acquisition-related
    expenses.
 
(4) The decline in stockholders' equity and the increase in long-term debt
    reflect the impact of the repurchase of 2.6 million shares of Common Stock
    and Class B Common Stock for $36.4 million on May 27, 1994.

                                  RISK FACTORS
 
    In addition to the other information contained in this Prospectus, the
following risk factors should be carefully considered when evaluating an
investment in the shares of Common Stock offered hereby.
 
CONCENTRATION OF REVENUE
 
    Approximately 49%, 69%, 76% and 90% of the Company's total revenue in 1994,
1993, 1992 and 1991, respectively, was derived from contracts or subcontracts
funded by the U.S. Government, which includes contracts funded by the DOD that
accounted for approximately 32%, 47%, 50% and 67% of the Company's total revenue
in such years, respectively. Although the percentage of the Company's revenue
that is derived from U.S. Government contracts has decreased, the Company
believes that the success and development of its business will continue to be
dependent upon its ability to participate in U.S. Government contract programs.
Accordingly, the Company's financial performance may be directly affected by
changes in U.S. 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 proposals to abolish certain
government agencies or departments, curtailment of the U.S. Government's use of
technology services firms, the adoption of new laws or regulations,
technological developments and general economic conditions. These factors could
cause U.S. Government agencies to exercise their right to terminate existing
contracts for convenience or not to exercise options to renew.
 
    Certain of the Company's contracts individually contribute a significant
percentage of the Company's revenue. In 1994, the Company's largest contract (by
revenue) generated approximately 9% of the Company's total revenue, and the ten
largest and 30 largest contracts (by revenue) generated approximately 37% and
53% of the Company's total revenue, respectively. Termination of such contracts,
or the Company's inability to renew or replace such key contracts when they
expire, could have a material adverse effect on the Company.
 
    Approximately 16% and 14% of the Company's revenue in 1994 was derived from
contracts funded by the Saudi and the German governments, respectively. See
"--International Operations".
 
CONTRACTS WITH U.S. FEDERAL, STATE AND LOCAL GOVERNMENTS
 
    U.S. Government contracts, by their terms, generally can be terminated at
any time by the U.S. Government, without cause, for the convenience of the U.S.
Government. If a U.S. Government contract is so terminated, the Company would be
entitled to receive compensation for the services provided or costs incurred
through the time of termination and a negotiated amount of profit on the
contract. Government contractors who fail to comply with applicable government
procurement-related statutes and regulations may also be subject to potential
contract termination, suspension or debarment from contracting with the
Government, or other remedies. Most U.S. Government contracts are also subject
to modification 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 U.S. Government auditors.
Further, U.S. Government contract awards may be protested by competitors.
 
    The Company in the ordinary course of its business occasionally performs
services for U.S. Government clients in advance of receiving a funded
contractual document. The Company does so with the expectation that such
contractual authorization will be obtained. As of December 31, 1994, the Company
had recognized no material amounts of revenue for U.S. Government clients for
which
 
                                       8
<PAGE>
funding had not been obtained; however, no assurance can be given that the
Company will not experience material losses relating to this practice in the
future.
 
    Approximately $45 million in revenue (6% of total revenue) in 1994 was
derived from subcontracts with prime contractors on U.S. Government contracts.
Accordingly, the Company may be adversely affected if a prime contractor fails
to perform satisfactorily or is unable or unwilling, for financial or other
reasons, to meet its obligations to the Company.
 
    Many of the types of provisions governing U.S. Government contracts
described above also apply to the Company's contracts with state and local
governments and their agencies. In addition, with respect to state and local
government clients, budgeting pressures and other financial constraints may
result in reductions in funding of various state and local government programs,
which may affect the ability of the Company to obtain new contracts with state
and local governments, cause state and local governments to exercise their right
to terminate existing contracts for convenience or not to exercise their options
thereunder and may result in the extension of the procurement and contract
funding process over a longer period of time.
 
INTERNATIONAL OPERATIONS
 
    The Company has recently increased its efforts to build its presence in
international markets. The Company recognized approximately $336 million in
revenue (43% of total revenue) in 1994 from contracts funded by international
clients. While management believes that BDM's experience serving the domestic
market translates into an ability to serve international markets, no assurance
can be given that the Company's efforts will succeed.
 
    The Company recognized approximately $194 million in revenue (25% of total
revenue) in 1994 from contracts with foreign defense agencies and approximately
$54 million in revenue (7% of total revenue) in 1994 from contracts with other
foreign government agencies. A significant amount of this revenue was derived
from contracts funded by foreign governments under the U.S. Government's Foreign
Military Sales ("FMS") program. FMS contracts involve the provision of services
to certain foreign governments, procured through U.S. Government contracting
mechanisms, but funded by the foreign governments themselves. The Company could
be materially adversely affected as a result of any political instability or
financial constraints experienced, or decisions to decrease funding, by such
foreign governments.
 
    In 1993, the Company acquired a 45% interest in IABG pursuant to a plan of
privatization by the German Government. In connection with the acquisition, the
Company entered into an agreement by which the Company votes 53% of the shares
of IABG except in those instances in which the German Federal Ministry of
Defense determines that an issue before the shareholders affects German national
security interests. In addition, BDM has received an informal commitment from
the German Government to use its best efforts to continue to direct business to
IABG through 1996, although there can be no assurance that IABG will receive
such business. This commitment will terminate at the end of 1996.
 
ENTRY INTO NEW MARKETS
 
    The Company has continued to diversify into new markets. These markets for
services offered by the Company are highly competitive, with numerous
competitors having substantially greater experience, market presence and
resources than the Company. There can be no assurance that the Company will be
successful in future efforts to enter into these markets.

CONTRACT PROFIT EXPOSURES
 
    The Company's services are provided primarily through three types of
contracts: fixed-price, time-and-material and cost-reimbursable contracts.
Approximately 30% of the Company's total revenue in 1994 was attributable to
fixed-price contracts which require the Company to perform services under a
contract at a stipulated price. The Company derived approximately 27% of its
total revenue during the same period from time-and-material contracts which
reimburse the Company for the number of labor hours expended at established
hourly rates negotiated in the contract, plus the cost of materials incurred.
The balance of the Company's contracts (approximately 43%) are cost-reimbursable
contracts under which the Company is reimbursed for all actual costs incurred in
performing the contract to the extent that such costs are within the contract
ceiling and allowable under the terms of the contract, plus a fee or profit.
 
    The Company assumes greater financial risk on fixed-price type contracts
than on either time-and-material or cost-reimbursable contracts. As the Company
increases its commercial business, it believes that an increasing percentage of
its contracts will be fixed-price. Failure to anticipate technical problems,
estimate costs accurately or control costs during performance of a fixed-price
contract may reduce the Company's profit or cause a loss. Greater risks are
involved under time-and-material contracts than under cost-reimbursable
contracts because the Company assumes the responsibility for the delivery of
specified skills at a fixed hourly rate. Although management believes that
adequate provision for its fixed-price and time-and-material contracts is
reflected in the Company's financial statements, no assurance can be given that
this provision is adequate or that losses on fixed-price and time-and-material
contracts will not occur in the future.
 
COMPETITION
 
    The markets for the Company's services are highly competitive. The Company's
competitors include large, diversified firms with substantially greater
financial resources and larger technical staffs than the Company as well as
firms which receive preferences under government set-aside programs. The U.S.
Government's in-house capabilities, federal (nonprofit) contract research
centers and universities are also competitors of the Company because they
perform certain types of services that might otherwise be performed by the
Company. For commercial and state and local clients, the Company also faces
competition from in-house capabilities resident in client organizations.
 
ACQUISITIONS AND STRATEGIC ALLIANCES
 
    The Company has made several acquisitions since its formation and may make
additional acquisitions in areas related to its current lines of business.
Although the Company is not currently engaged in any material acquisitions, the
Company's strategy is to grow through acquisition as well as internally.
However, no assurance can be given that the Company will make additional
acquisitions, that past or future acquisitions will prove to be successful or
that the Company will successfully manage the growth attributable to such
acquisitions. Moreover, the Company has incurred, and may incur, substantial
debt and non-cash amortization expenses in making acquisitions.
 
    The Company has formed strategic alliances in the form of joint ventures to
gain access to markets in Oman, Saudi Arabia, Turkey and Egypt. As the Company
seeks to expand internationally, it may be necessary to form new strategic
alliances to gain access to particular foreign markets. No assurance can be
given, however, that the Company will be able to maintain its existing alliances
or form new desirable alliances in the future. See "Business--Joint Ventures in
the Middle East."

ENVIRONMENTAL MATTERS
 
    One of the Company's subsidiaries, Vinnell, along with another potentially
responsible party ("PRP"), entered into a consent decree with the Environmental
Protection Agency ("EPA") in 1992, by which Vinnell and the other PRP are
obligated to reimburse the EPA for costs incurred in its assessment and
monitoring and to undertake work to address the environmental exposure as
defined in the consent decree relating to an asbestos mine owned by Vinnell
prior to the time Vinnell was acquired by the Company. Operations at such mine
ceased in May 1974. Although management believes that its accrual for this
contingency is sufficient to cover costs to be incurred related to the
subsidiary's performance pursuant to the consent decree, there can be no
assurance that additional costs will not be incurred. Another of the Company's
subsidiaries was previously notified by the Massachusetts Department of
Environmental Protection that it is also one of several PRP's in an
environmental matter arising as a result of work performed on a contract with
the United States Air Force ("USAF") in 1986. The Company has been, and
management believes the Company will continue to be, reimbursed by the USAF for
all costs incurred in connection with addressing the claimed environmental
hazard associated with the former contract. See Note 17 of the Notes to
Consolidated Financial Statements. In addition, the Company anticipates
increasing its environmental consulting activity which includes work related to
environmental remediation. Such business may expose the Company to additional
environmental risks in the future.
 
STAFFING REQUIREMENTS
 
    The Company's business is dependent on its ability to attract, retain and
mobilize a highly trained technical staff. An inability to maintain a sufficient
number of trained personnel or to relocate or position such personnel on certain
contracts performed at remote locations could have a material adverse effect on
the Company's contract performance or its ability to capitalize on market
opportunities.
 
    As a corporation organized under the laws of and operating in Germany, IABG
is subject to the German Co-Determination Law. Under this law, certain German
workers have a right to representation on supervisory boards of a company and,
through Workers' Councils, have a say in issues relating to corporate
operations, particularly those having a direct impact on workers. No assurance
can be given that this law will not adversely affect the Company's ability to
operate IABG.
 
PROPRIETARY INFORMATION
 
    The Company believes that its business is dependent on its technical and
organizational knowledge, practices and procedures. The Company claims a
proprietary interest in certain of its work products, software programs,
methodologies and know-how. Some of the proprietary information is protected by
confidentiality agreements and other means. There can be no assurance, however,
that these measures will prevent the unauthorized disclosure or use of the
Company's technical knowledge, practices and procedures or that others may not
independently develop similar knowledge, practices or procedures.
 
    The U.S. Government has certain proprietary rights to software programs and
other products that result from the Company's services under U.S. Government
contracts or subcontracts. The U.S. Government may disclose such information to
third parties, including competitors of the Company. In the case of
subcontracts, the prime contractors may also have certain rights to such
programs and products.

CONTROL BY CURRENT STOCKHOLDERS
 
    Upon completion of the Offerings, The Carlyle Partners Leveraged Capital
Fund I, L.P. ("The Carlyle Fund"), BDM Acquisition Partners II, L.P. ("BDM
Acquisition II") and BDM Acquisition Partners, L.P. ("BDM Partners"), three
limited partnerships controlled by The Carlyle Group, L.P. ("Carlyle"), will
have, in the aggregate, approximately 50% of the Company's voting power (or 48%
if the Underwriters' over-allotment options are exercised in full).
Consequently, since it will have approximately 50% of the Company's voting power
upon completion of the Offerings, Carlyle will be able to elect all of the
directors of the Company. Further, Carlyle will be able to control the outcome
of all matters submitted to a vote of the Company's stockholders, as well as the
Company's management, operations and policies. See "Certain
Transactions--Stockholders Agreement."
 
    Certain agreements to which the Company is a party contain provisions that
may have the effect of deterring a change in control of the Company. Options
granted under the 1990 and 1994 Stock Option Plans will immediately vest upon a
merger in which the Company is not the surviving entity or upon a sale of
substantially all the assets or more than 80% of the then outstanding capital
stock of the Company. In addition, an Investor Stock Purchase Agreement, dated
October 23, 1990, between the Company and certain stockholders, as amended (the
"Investor Agreement") restricts the transferability of the Company's securities
held by Carlyle and such stockholders. See "Certain Transactions--Stockholders
Agreement" and "--Investor Agreement."
 
ABSENCE OF A PUBLIC MARKET AND POSSIBLE VOLATILITY OF STOCK PRICE
 
    Prior to the Offerings, there has been no regular public market for the
Common Stock, and there can be no assurance that a regular trading market will
develop or be sustained after the Offerings. The initial public offering price
for the Common Stock will be determined through negotiations between the Company
and the Underwriters based on factors described under the caption "Underwriting"
and may not be indicative of the market price after the Offerings.
 
    The market price for the Common Stock may be highly volatile. The Company
believes that factors such as announcements by it, or its competitors or
suppliers, or quarterly variances in financial results could cause the market
price of the Common Stock to fluctuate substantially. In addition, the stock
market may experience extreme price and volume fluctuations which often are
unrelated to the operating performance of specific companies. Market
fluctuations or perceptions regarding the Company's industry, as well as general
economic or political conditions, may adversely affect the market price of the
Common Stock.
 
SHARES ELIGIBLE FOR FUTURE SALE
 
    Upon the completion of the Offerings, the Company will have 11,975,656
shares of Common Stock and Class B Common Stock outstanding. Of these shares,
the 2,500,000 shares of Common Stock sold in the Offerings, the 1,339,217 shares
of Common Stock sold in the 1991 Offering and the 1,562,500 shares of Common
Stock issued, or to be issued, upon exercise of stock options granted under the
1990 Stock Option Plan that have been registered under the Securities Act
pursuant to registration statements on Form S-8 will be freely tradable without
restriction under the Securities Act by persons other than "affiliates" of the
Company. In addition, the Company currently intends to register the shares of
Common Stock under the 1994 Stock Option Plan pursuant to which options to
purchase 186,432 shares have been granted. If registered, such shares will be
freely tradable as described above. An additional 360,000 shares of Common Stock
are reserved for issuance under the Company's Employee Stock Purchase Plan (the
"Employee Stock Purchase Plan") of which 231,748 shares have been issued as of
March 31, 1995, and are freely tradable without restriction under the Securities
Act. The remaining 7,653,515 shares of issued and outstanding Common Stock and
Class B Common Stock were acquired in transactions
 
                                       12
<PAGE>
that were exempt from registration under the Securities Act and consequently may
not be resold unless they are registered under the Securities Act or are sold
pursuant to an applicable exemption from registration, including Rule 144 under
the Securities Act. See "Shares Eligible For Future Sale."
 
    Pursuant to the Investor Agreement, the stockholders who are subject thereto
have certain demand and piggy-back registration rights. See "Shares Eligible for
Future Sale--Registration Rights."
 
DILUTION
 
    Purchasers of the shares of Common Stock offered hereby will incur immediate
and substantial dilution in the net tangible book value of their investment. See
"Dilution."

                                  THE COMPANY
 
    BDM is a multinational information technology company that operates in three
interrelated markets:
 
    . SYSTEMS AND SOFTWARE INTEGRATION. The Company creates information and
      other computer-based systems that are tailored to specific public and
      private sector client needs. It does so by applying commercial
      off-the-shelf hardware and software, purchased from multiple vendors, to
      user-oriented system solutions with integrated software developed by the
      Company. BDM's expertise includes consolidating computer operations and/or
      migrating from older mainframe-based computer systems to newer, more
      flexible, standardized open systems based on client/server architectures
      linked by local and wide-area networks. Current multi-year contracts in
      this market include development and delivery of client/server as well as
      mainframe-based management information and transaction processing systems,
      real time control systems (such as air traffic control), automated
      distribution systems and computer networks. Systems and Software
      Integration revenue in 1994 was approximately $197 million (26% of total
      revenue) and has grown at a compound annual growth rate of 33% since 1991
      (31% excluding acquisitions).
 
    . COMPUTER AND TECHNICAL SERVICES. The Company provides a broad range of
      scientific, engineering, technical assistance and consulting services
      spanning the complete life-cycle of complex programs. Typical assignments
      involve system concept development, requirements analysis, training and
      systems testing. Specific examples include advanced modeling and
      simulation services to help clients improve planning, testing and
      training; the use of image technology to enhance security and
      intelligence; numerous programs in command, control, communications,
      computers and intelligence to assist the U.S. military services and other
      clients; and environmental remediation and waste management services.
      Through this work, BDM also gains insights into its clients' operations,
      identifies potential cost-effective systems solutions and thereby
      positions itself to capture complex systems and software integration
      opportunities. Computer and Technical Services revenue in 1994 was
      approximately $491 million (63% of total revenue) and has grown at a
      compound annual growth rate of 36% since 1991 (4% excluding acquisitions).
 
    . ENTERPRISE MANAGEMENT AND OPERATIONS. The Company manages and operates
      research and development centers, test facilities and logistics and
      training centers on behalf of its clients. Examples include managing and
      operating the U.S. government's primary petroleum energy research
      facility; various European test facilities for vehicles, aircraft and
      spacecraft; and five Job Corps Centers. These activities, together with
      the Company's capabilities in Systems and Software Integration and
      Computer and Technical Services, enable BDM to provide the full range of
      services that its clients often require. Enterprise Management and
      Operations revenue in 1994 was approximately $86 million (11% of total
      revenue) and has grown at a compound annual growth rate of 71% since 1991
      (24% excluding acquisitions).
 
BUSINESS STRATEGIES AND STRENGTHS
 
    BDM is pursuing a strategy of growth and diversification through its
decentralized subsidiaries--BDM Federal, BDM Technologies, BDM Europe and
Vinnell--to become a global IT company. Total revenue has grown from $297
million in 1991 to $774 million in 1994, a compound annual growth rate of 38%
(14% excluding acquisitions). Building on its core competencies developed over
35 years of serving the DOD and its reputation for high quality professional
work, BDM is transferring its expertise to selected public and private sector
clients in targeted vertical markets.
 
                                       14
<PAGE>
    The aggregate stated award value of new contracts won by the Company in 1994
exceeded $1 billion for the second consecutive year. No single contract
represented more than 10% of total revenue in 1994. See "Business--Company
Operations" for a description of some of the Company's contracts.
 
    BDM attributes much of its recent performance to the following strategies
and strengths:
 
    EMPHASIS ON INFORMATION TECHNOLOGY SYSTEMS MARKETS. BDM has placed an
emphasis on strengthening its ability to compete in the fast-growing systems and
software integration marketplace, focusing on large multi-year contracts ranging
upward from $50 million. The Company has pursued its information systems
strategy through such actions as the establishment of BDM Technologies, an IT
company focused on commercial and state and local government clients, and the
acquisition of two European companies that possess significant IT systems
capabilities. To enhance the Company's ability to compete in targeted vertical
information systems markets, the Company is developing a common IT strategy,
standardized software methodologies, and a pool of systems professionals who can
be deployed across each of its subsidiaries. The Company believes that its
position and reputation in IT markets are reflected by its dollar-based
competitive win rate of 51% of the Company's bids on contracts awarded in 1994.
 
    EXPANSION INTO TARGETED MARKETS. The Company has successfully transitioned
its expertise gained from work with the DOD into such vertical markets as
environmental/waste management, energy research and development, air traffic
control, work force development and training, education technologies, health and
human services information management, and manufacturing and distribution
automation for civil government and commercial clients. BDM has penetrated the
civil government business through systems development and integration contracts,
such as its EDGAR system for the SEC, and has built a market position in health
and welfare systems for state governments and education systems for state and
local school districts. BDM's commercial and civil government business (both
international and domestic) increased from $92 million in 1991 to $336 million
in 1994, representing approximately 43% of the Company's 1994 revenue.
 
    GLOBAL DIVERSIFICATION. In 1994, BDM generated more revenue from
international clients ($336 million) than from all sources in 1991 ($297
million). The Company believes that its ability to serve clients on a global
basis is a competitive differentiator in the marketplace. The Company's overseas
presence allows it to project its core competencies into less competitive IT
markets which the Company believes will afford significant growth and margin
expansion opportunities. BDM has expanded vigorously into European and Middle
Eastern markets, aided by two key acquisitions, and has begun marketing in the
Pacific Rim.
 
    FOCUSED ACQUISITION PROGRAM. The Company is experienced in identifying and
consummating acquisitions and subsequently integrating acquired businesses into
existing operations. The Company intends to continue to pursue an acquisition
program, primarily focused on expanding its position in global information
technology markets. The Company will concentrate on identifying acquisition
targets, particularly those focusing on commercial clients, which have strong
existing management teams in place that can be integrated into BDM's
decentralized operating structure within a common overall strategy.
 
CORPORATE HISTORY
 
    The Company was formed in 1959 by Drs. Joseph V. Braddock, Bernard J. Dunn
and Daniel F. McDonald as "Braddock, Dunn & McDonald, Incorporated," which was
later reorganized as BDM International, Inc. (the "Predecessor Company"). The
Predecessor Company was a public company from 1980 until 1988, when Ford
Aerospace, then a wholly owned subsidiary of Ford Motor Company ("Ford"),
acquired all of the outstanding stock of the Predecessor Company.
 
                                       15
<PAGE>
    In October 1990, on behalf of certain investors, Carlyle, a private merchant
banking firm, formed BDM Holdings, Inc. ("Holdings"), a Delaware corporation,
and a wholly owned subsidiary corporation named New BDM, Inc. ("New BDM"), which
acquired substantially all of the assets of the Predecessor Company (the "1990
Acquisition"). See "Certain Transactions--1990 Acquisition." Shortly after the
1990 Acquisition, New BDM changed its name to BDM International, Inc. In
December 1992, Holdings and BDM International, Inc. changed their names to BDM
International, Inc. and BDM Federal, Inc. ("BDM Federal"), respectively.
 
    In February 1991, the Company sold 1,339,217 shares of Common Stock at a
purchase price of $4.00 per share to certain employees, directors and
consultants of the Company in an offering (the "1991 Offering") registered under
the Securities Act, and sold an additional 1,500,000 shares of Common Stock to
Carlyle at a purchase price of $4.00 per share. Since the 1991 Offering, the
Company has filed reports under the Exchange Act; however, there has been no
public market for the Common Stock. See "Available Information."
 
    In March 1992, the Company acquired the outstanding common stock of Vinnell,
a company that provides training and logistics services largely in the Middle
East. In January 1993, the Company began operating a new subsidiary, BDM
Technologies, Inc. ("BDM Technologies"), to focus on commercial and state and
local government clients. Effective January 1, 1993, a new subsidiary, BDM
Europe BV ("BDM Europe"), acquired two European businesses, FACE Industrial
Automation BV and Logisticon BV, and merged them into a single entity called
FACE Holding BV ("FACE"), located in Eindhoven, The Netherlands. FACE provides
systems integration and technical services to industrial clients, primarily in
the areas of automated distribution and advanced manufacturing systems. In
November 1993, BDM Europe acquired management control, through a 45% ownership
interest, in IABG, a German company that provides test and evaluation and
information services, principally to the German Government. The interest was
acquired primarily from Industrieverwaltungsgesellschaft AG ("IVG") under a
privatization plan approved by the relevant ministries of the German Government,
the principal owner of IVG. In February 1994, the Company acquired Geoscience
Consultants, Ltd. ("GCL"), a company that provides environmental assessment and
engineering services to industrial and governmental clients, which is reported
under BDM Federal.
 
    The Company's headquarters and executive offices are located at 1501 BDM
Way, McLean, Virginia 22102-3204, and its telephone number is (703) 848-5000.

<PAGE>
                                USE OF PROCEEDS
 
    The Company intends to use the net proceeds from the sale of the 2,500,000
shares of Common Stock offered by the Company, estimated to be approximately
$41,200,000 (based on an assumed initial public offering price of $18.00 per
share, the midpoint of the range stated on the cover page hereof, and after
deduction of the underwriting discounts and commissions and estimated expenses
payable by the Company), to repay outstanding debt under a credit agreement
dated July 20, 1993, among the Company, certain subsidiaries of the Company and
the banking institutions named therein, with CoreStates Bank, N.A. as Agent, as
amended (the "Credit Facility") and under a subordinated promissory note given
in connection with the acquisition of Vinnell (the "Vinnell Note"). Pending
application of the net proceeds, the Company will invest such net proceeds in
short-term marketable securities.
 
    As of March 31, 1995 and May 31, 1995, borrowings under the Credit Facility,
totalled $60.0 million and $59.5 million, respectively. The Credit Facility
bears interest at a variable rate, which, as of March 31, 1995, was
approximately 8.4% per annum, and matures on July 20, 1998. Borrowings under the
Credit Facility during 1994 were used to repurchase 2,600,000 shares of Common
Stock and Class B Common Stock from certain shareholders and for general working
capital purposes. The aggregate principal amount outstanding under the Vinnell
Note, as of March 31, 1995, was $3.7 million. The Vinnell Note bears interest at
the rate of 10% per annum and matures on March 13, 1996. See "Certain
Transactions--1990 Acquisition," "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Liquidity and Capital Resources,"
"Dividend Policy" and Note 9 of the Notes to Consolidated Financial Statements.
 
                                DIVIDEND POLICY
 
    The Company does not have a policy of paying regular dividends and has no
present intention of paying any dividends. The payment of dividends is subject
to the discretion of the Board of Directors of the Company and will depend on
the Company's results of operations, financial position and capital
requirements; general business conditions; restrictions imposed by financing
arrangements, if any; legal and regulatory restrictions on the payment of
dividends; and other factors, such as continued growth opportunities in which to
invest, which the Board of Directors deem relevant. The Company paid a dividend
on December 15, 1993, of $.50 per share of Common Stock and Class B Common
Stock. The payment of future dividends by the Company should not be assumed.
 
                                       17
<PAGE>
                                    DILUTION
 
    The net tangible book value of the Company at March 31, 1995, was $31.8
million, or $3.35 per share. Net tangible book value per share represents the
amount of total tangible assets less total liabilities, divided by the number of
shares of Common Stock and Class B Common Stock outstanding. As the following
table demonstrates, after giving effect to the sale of 2,500,000 shares of
Common Stock by the Company in the Offerings, at an assumed initial public
offering price of $18.00 per share, the midpoint of the range stated on the
cover page hereof, and after deducting anticipated offering expenses and
underwriting discounts and commissions, the pro forma net tangible book value of
the Company at March 31, 1995, would have been $73.0 million, or $6.09 per
share, representing an immediate $11.91 per share dilution to new investors
purchasing shares of Common Stock at the assumed initial public offering price.

(1) As of March 31, 1995, there were outstanding options to purchase 81,979
    shares of Common Stock at an average exercise price of $.01 per share under
    the Management Incentive Stock Purchase Program and 1,497,756 shares of
    Common Stock at exercise prices of $4.00-- $17.25 per share under the 1990
    and 1994 Stock Option Plans. See "Management--Management Incentive Stock
    Purchase Program" and "--1990 and 1994 Stock Option Plans." If all the
    options outstanding as of March 31, 1995 under the Management Incentive
    Stock Purchase Program and the 1990 and 1994 Stock Option Plans were to be
    immediately converted to Common Stock, dilution per share to new investors
    would be $12.62.
 
(2) On May 5, 1995, the Company granted additional options to purchase 57,500
    shares of Common Stock. See "Management Incentive Stock Purchase Program"
    and "--1990 and 1994 Stock Option Plans."

    The following table sets forth the capitalization of the Company as of March
31, 1995 and as adjusted to reflect the sale of the 2,500,000 shares of Common
Stock by the Company (at an assumed initial public offering price of $18.00 per
share, the midpoint of the range stated on the cover page hereof) and the
application of the net proceeds therefrom. See "Use of Proceeds." This table

(1) On November 16, 1993, the Company acquired a 45% interest in IABG and
    entered into an agreement which gives the Company voting control of IABG and
    permits the Company to manage IABG's operations. The Company's financial
    statements consolidate IABG's financial position and results of operations
    and report the remaining owners' 55% interest as a minority interest. This
    acquisition was accounted for as a purchase, and the Company's consolidated
    results of operations include IABG from the date of its acquisition through
    its subsidiary, BDM Europe.
 
(2) On March 13, 1992, the Company acquired the outstanding common stock of
    Vinnell for approximately $29.6 million, including transaction expenses.
    This acquisition was accounted for as a purchase, and the Company's
    consolidated results of operations include Vinnell from the date of its
    acquisition.
 
(3) The Company was acquired in an investor and management led buyout on October
    23, 1990. The acquisition was accounted for as a purchase, and $93.5 million
    of indebtedness of the Company related to the buyout was incurred. The
    results of 1991 and 1990 reflect certain one-time acquisition-related
    expenses.
 
(4) Per share data for the nine months ended September 30, 1990 are not
    applicable because the Company was a wholly owned subsidiary of Ford
    Aerospace Corporation ("Ford Aerospace") for that period.
 
(5) The decline in stockholders' equity and the increase in long-term debt
    reflect the impact of the repurchase of 2.6 million shares of Common Stock
    and Class B Common Stock for $36.4 million on May 27, 1994.
 
(6) Balance sheet data for 1990 reflect purchase accounting adjustments made
    relating to the sale of the Company in 1990. See "The Company--Corporate
    History."
 
(7) Pro forma earnings per share, giving effect to the use of proceeds from the
    public offering to repay outstanding debt and the issuance of shares 
    pursuant to the offering, would have been $0.31 per share for the three 
    months ended March 31, 1995 and $1.10 for the year ended December 31, 1994.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
    In 1994, the Company achieved significant growth in revenue and net income,
as well as success in its diversification strategy, strengthening its position
as a multinational information technology company. With revenue of $774.2
million and net income of $13.1 million, 1994 was the third consecutive year of
significant growth, from a revenue base of $296.8 million and a net income base
of $0.5 million in 1991. The Company is pursuing its strategic markets--Systems
and Software Integration, Computer and Technical Services, and Enterprise
Management and Operations--through both internal growth and acquisitions.
 
    Internal growth has been focused on Systems and Software Integration
activities where the Company has transferred its core competencies developed in
connection with DOD programs to commercial, international and U.S. civil
government clients. In addition, the Company formed BDM Technologies in 1993 to
provide greater focus on commercial and state government clients by, in part,
using expertise developed historically within BDM Federal. In its two years of
existence, BDM Technologies has grown rapidly and built a solid, full-service IT
business.
 
    Acquisitions have been integral to BDM's growth and diversification
strategy. The acquisition of Vinnell in 1992 increased the Company's presence in
the Middle East and its access to federal civil government opportunities. BDM
Europe was formed with the purchase of FACE in 1993 to provide access to
commercial clients in The Netherlands and other European countries that can
utilize the Company's capabilities in such areas as warehouse automation and
advanced manufacturing services. BDM Europe was significantly expanded with the
Company's acquisition of a 45% interest in IABG in 1993 providing access to
growing German and Central European markets. The Company believes that the
European IT markets are less mature and therefore offer significant
opportunities for growth.
 
    BDM targets growing markets in which it can draw upon its broad range of IT
and related expertise to win business with both public and private sector
clients, while continuing to focus on its U.S. defense business. Through a
combination of internal growth and acquisitions, the Company's client base has
evolved from one in which contracts with the DOD accounted for approximately 67%
of total revenue in 1991 to a diversified client base in which DOD contracts
accounted for approximately 32% of total revenue in 1994.
 
    The combination of internal growth and acquisitions has fundamentally
changed BDM into a much larger, international company offering a wide variety of
services targeted at growing vertical markets in the United States and abroad.
The Company's diversification has also enhanced its financial results and
condition and has helped generate contract awards in 1994 exceeding $1 billion
for the second year in a row. The Company finished 1994 with an awarded but
unperformed contract backlog exceeding $1.5 billion.
 
    For information regarding the Company's results by geographical region, see
Note 16 of the Notes to Consolidated Financial Statements. Specific discussion
of geographic trends and fluctuations for each line item in the Statements of
Operations is discussed in each respective area below.

    REVENUE. Revenue increased 39% in 1994 over 1993, or $216.0 million. This
increase was due primarily to the inclusion of the results of IABG in BDM Europe
for 12 months in 1994 versus six weeks in 1993 and strong results at BDM Federal
and BDM Technologies. Vinnell's revenue was up slightly in 1994 versus 1993. In
1993, revenue for the Company increased $133.9 million, or 32%, over 1992. This
increase was due primarily to strong results at BDM Federal, the inclusion of
Vinnell for 12 months in 1993 versus nine and one half months in 1992, the
acquisition of IABG and the formation of BDM Technologies.
 
    Revenue generated by subsidiary is identified in the following table

(1) BDM Federal revenue in 1994 includes revenue from GCL from its date of
    acquisition.
 
(2) BDM Europe revenue in 1993 includes IABG and FACE from their respective
    dates of acquisition.
 
(3) Vinnell revenue in 1992 is reflected from its date of acquisition.
 
    BDM Federal revenue increased by 6% and 14% in 1994 and 1993, respectively,
over the preceding year. The increase in each year reflected increased revenue
from the Company's professional services which grew 12% and 5% in 1994 and 1993,
respectively, over the preceding year. Revenue includes sales of material
consisting primarily of computer hardware and software to clients. Such sales of
material under large contracts may fall disproportionately into one period
 
                                       23
<PAGE>
rather than being spread evenly over the term of a contract. Sales of material
as a percentage of total revenue were higher in 1993 than in 1994, accounting
for the higher revenue growth in 1993.
 
    BDM Technologies revenue increased 120% in 1994 over 1993. This increase was
attributable to contract awards exceeding $100 million in 1994 for systems
integration and consulting services from state government and commercial
clients.
 
    BDM Europe revenue in 1993 reflected less than six weeks of IABG operations.
Revenue increased 4% in 1994 compared to 1993 when including IABG's revenue for
the full calendar year (including the period prior to its acquisition). IABG was
a government controlled not-for-profit entity, and the Company's objective is to
transition IABG's business base from one heavily dependent on German Government
defense spending to one with a more diversified governmental and commercial
client base.
 
    Vinnell revenue increased by 3% in 1994 compared to 1993 and by 15% in 1993
compared to its revenue for the full calendar year of 1992 (including the period
prior to acquisition by the Company). Growth in 1994 resulted from net expansion
in Vinnell's international training efforts of $7.1 million, offset by a $3.0
million reduction in revenue from domestic training. The increase in Vinnell's
revenue in 1993 resulted from substantial additions to both its international
and domestic training programs.
 
    For the three months ended March 31, 1995, revenue for the Company increased
$26.7 million or 16% over the same period in 1994. All subsidiaries contributed
to this growth. The increase in BDM Federal revenue reflected a 7% increase in
professional services and a 17% increase in sales of material. BDM Technologies
added significant revenue from the performance of two state government IT
contracts awarded subsequent to the first quarter of 1994. BDM Europe 's
increase in revenue was due to exchange rate fluctuations.
 
    COST OF SALES. Cost of sales, which includes salaries, benefits,
subcontractor expenses, material and overhead costs, increased slightly as a
percentage of revenue in each of 1994, 1993 and 1992. The increase for 1994 over
1993 is due largely to the development of business in BDM Technologies where a
large percentage of the cost of sales was attributable to purchases of computer
hardware sold to clients for lower margins than professional services. In
addition, the acquisition and consolidation of IABG, which has lower margins
than other sectors of BDM's business, contributed to the increase in 1994.
 
    For the three months ended March 31, 1995, the cost of sales was 81.8% of
total revenue consistent with the cost of sales for the three months ended March
31, 1994, which was 81.9% of total revenue.
 
    SELLING, GENERAL AND ADMINISTRATIVE. Selling, general and administrative
("SG&A") expense, including the Company's research and development ("R&D")
costs, decreased as a percentage of revenue in 1994 from 1993 but increased in
1993 from 1992. The increase in 1993 from 1992 was partially attributable to
$5.3 million in discontinued R&D activities and also to start-up costs related
to BDM Technologies. SG&A in 1994 included $3.9 million in such R&D activities.
As part of its R&D efforts, the Company incurred $3.9 million and $5.3 million
during 1994 and 1993, respectively, as part of a project to create an advanced
manufacturing capability. The Company's funding participation ceased in June
1994. In January 1995, the Company entered into an agreement in which it
exchanged a three year license to its developed technology for 36 monthly
installment payments of common stock of the licensee. Excluding these
discontinued activities, SG&A as a percentage of revenue were 10.2%, 10.5% and
9.9% for 1994, 1993 and 1992, respectively.
 
    For the three months ended March 31, 1995, SG&A as a percentage of revenue
was 10.1%, down from 11.7% for the three months ended March 31, 1994, due to the
discontinuance of R&D activity (approximately $2.0 million in the three months
ended March 31, 1994) and improved cost controls.
 
                                       24
<PAGE>
    DEPRECIATION, AMORTIZATION AND OTHER. Depreciation expense increased $5.1
million in 1994 over 1993 due primarily to the inclusion of a full year of
operations of BDM Europe. Amortization and other expenses consist largely of
certain indirect non-cash charges incurred by the Company which are typically
not allocable to government contracts, including amortization of intangibles and
the pension charges required by Statement of Financial Accounting Standards No.
87--Employers' Accounting for Pensions (SFAS 87). Amortization and other
expenses increased by $3.4 million in 1994 as a result of an increase in the
Company's unallocable pension charge of $2 million, a $0.8 million increase in
amortization expense associated with intangibles of recent acquisitions, and
approximately $0.6 million expensed as a result of the Company's decision to
delay its initial public offering.
 
    For the three months ended March 31, 1995, depreciation, amortization and
other expenses increased to $5.6 million from $4.9 million for the three months
ended March 31, 1994. Included in the 1995 amount is a $1.6 million write-off of
the unamortized value of goodwill incurred as a result of the FACE acquisition
in 1993.
 
    The unamortized goodwill for FACE totaling $1.6 million was expensed during
the three months ended March 31, 1995, as it was determined to be no longer
recoverable. Several factors contributed to this change in recoverability.
Transfer of technology from one industry to another within the acquired
company was not realized and synergies between BDM technologies and acquired
technologies did not result in an expansion of the customer base as expected. In
addition, an economic downturn in the Netherlands contributed to a deterioration
in the revenue base. These factors resulted in negative cash flows projected for
this particular business.
 
    In addition, unamortized goodwill from a separate acquisition totaling $0.4
million was expensed during 1994, as it was determined to be no longer
recoverable. The change in recoverability was driven primarily by the loss of a
significant contract performed by the acquired company, which resulted in
negative cash flows projected for this particular business.
 
    INTEREST EXPENSE. Net interest expense has declined steadily over the three
year period. While debt balances increased to $82.8 million as of year end 1994
from $48.5 million as of year end 1993, lower interest rates and the inclusion
of a full year of interest income from BDM Europe more than offset higher
interest expense. The debt balance in 1993 exceeded the 1992 balance by
approximately $10 million; however, interest expense was lower in 1993 compared
to 1992 due to the refinancing of 12% subordinated debt with floating rate debt.
 
    For the three months ended March 31, 1995, interest expense increased due to
a weighted average debt balance of $80.7 million versus $58.0 million during the
same period in 1994. The increase in debt in 1995 was the result of the
Company's repurchase of 2.6 million outstanding shares of Common Stock and Class
B Common Stock from institutional investors in May 1994. In addition, the
weighted average interest rate incurred during the quarters ended March 31, 1995
and 1994 was 8.5% and 5.5%, respectively.
 
    MINORITY INTEREST. The Company began deducting minority interest from
earnings with the acquisition of 45% of IABG in 1993. Minority interest
increased $1.0 million in 1994. This increase comes from a full year of IABG
minority interest and approximately $0.6 million from a new 60% owned Vinnell
joint venture, Saudi Strategic Services, Ltd., which began performance of a
contract in May 1994.
 
    For the three months ended March 31, 1995, minority interest increased by
$1.6 million to $2.2 million compared to the same period in 1994. As noted,
Vinnell began performing on a large contract as a 60% joint venture partner with
a Saudi Arabian company in May 1994. Minority interest recognized on this
contract during the first quarter of 1995 was $0.9 million. Of this amount, $0.4
million represented the finalization in March 1995 of profit negotiations
applicable to services provided since contract inception.
 
                                       25
<PAGE>
    Vinnell currently has a contract to provide training services to the Saudi
Arabian National Guard which represented 55% of its total revenue in 1994. The
contract was recompeted by the client in 1994, and, in the spring of 1995, a
joint venture in which the Company owns 51% was selected for an award of a three
year follow-on contract for $163 million beginning in July 1995. The contract's
future results of operations will be consolidated, and the other partner's
minority ownership interest of 49% will be reflected as a minority interest.
Accordingly, the Company expects reduced profits from this program.
 
    PROVISION FOR INCOME TAXES. The provision for income taxes increased as a
percentage of income before income taxes in 1994 to 42.6% from 40.9% in both
1993 and 1992 as a result of the effects of certain acquisitions which created
non-deductible goodwill. Additionally, certain tax benefits derived from the
acquisition of IABG were fully realized in the 1993 income tax provision.
Historically, the Company has been able to offset the effects of income
generated in high tax rate foreign jurisdictions with income earned in foreign
jurisdictions where favorable tax positions were negotiated. As a result the
overall effect of foreign earnings on the Company's tax provision has been
minimal. However, to the extent that any growth in the Company's international
operations occurs in high tax rate jurisdictions, the portion of the income tax
provision which is attributable to foreign earnings is likely to increase.
 
    For the three months ended March 31, 1995, the provision for income taxes
increased as a percentage of income before taxes to 51.6% compared to 43.1% for
the comparable 1994 period. The effective rate increase is the result of the
Company's expensing of $1.6 million in goodwill in the first quarter of 1995
which is not deductible for income tax purposes.
 
    EXTRAORDINARY ITEMS. In 1993, the Company recognized two extraordinary items
having the net effect of increasing net income by approximately $0.4 million, or
$.03 per share. In connection with the negotiation of the Credit Facility, the
Company expensed the carrying value of debt issue costs incurred with the prior
credit agreement of $2.3 million less a related income tax benefit of $1
million. In addition, the Company recognized an extraordinary gain related to
the elimination of a liability recognized at the time of the 1990 Acquisition,
resulting in a benefit of $3.0 million less a related income tax expense of $1.3
million.
 
EFFECTS OF INFLATION
 
    The Company's contract mix includes cost-reimbursable contracts which
represented 43%, 68% and 74% of total contract revenue in 1994, 1993 and 1992,
respectively, under which inflationary increases are passed on to the client.
The decline in the percentage of cost-reimbursable contracts reflects the full
year of operation at BDM Europe whose contract portfolio is primarily
time-and-material contracts. Total 1994 revenue from time-and-material contracts
increased to 27% in 1994 compared to 3% and 5% in 1993 and 1992, respectively.
The Company performs many significant, long-term fixed-price and
time-and-material contracts which expose it to the risks of inflationary
pressures on its costs. The Company expects to increase the percentage of
fixed-price contracts as it shifts to serving more commercial clients. The
contract revenue mix for the three months ended March 31, 1995, did not change
significantly from 1994.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    The Company's principal sources of liquidity and working capital continue to
be cash flow from operations and borrowings under the Credit Facility. In recent
years, the Company's cash flow from operations has been adequate to fund
internal growth. In addition, cash flow from operations has also contributed to
the reduction of outstanding debt, such as the retirement of $93.5 million of
debt assumed as part of the 1990 Acquisition in two years rather than the
originally planned five years and the retirement of the Vinnell acquisition debt
of $25 million in less than three years. Cash flow
 
                                       26
<PAGE>
from the Credit Facility has been utilized to fund other non-operating
activities, including capital expenditures, acquisitions, a stock buyback and a
dividend.
 
    Supplementing the cash flow from operations have been significant amounts of
advance payments for IABG contracts. As part of customary arrangements, IABG
continues to receive such advance payments from a large percentage of its client
base. Pursuant to the privatization plan for IABG, the German Government has
also indicated that it will continue the practice of advance payments.
 
    As an additional incentive to new investors acquiring IABG, the German 
Government pursuant to the privatization plan, also agreed to fund a portion of
a severance liability, established prior to the Company's acquisition of IABG,
in an amount equal to the principal balance of two notes held by IABG payable to
the German Government's Ministry of Defense ("MOD") for a total of $10 million. 
As payments  for the severance liability are made to terminated employees, the
MOD obligation is reduced by a similar amount. The Company made severance 
payments of $7.9  million during 1994. Also reducing cash flow from operations,
a rental deposit of approximately $5 million was made during 1994 in connection
with the IABG privatization.
 
    Other factors impacting cash flows from operations included increased income
tax payments in 1994 due to the use of the remaining net operating loss
carryforwards in 1993, and the timing of cash flows from customers and to
suppliers.
 
    Investing activities providing cash flow include certain provisions of the
IABG acquisition agreement in which the owners have guaranteed additional equity
infusions of $16 million during the two years following the November 1993
acquisition date. In November 1994, the first anniversary of the acquisition,
installment payments of $6.2 million were made which represents 77% of the total
required equity infusion. The remaining 23% portion of the required infusion, or
$1.9 million, is due from the portion of IABG still held in trust for sale to
employees and other investors and will be paid upon the closing of such sale
anticipated in the first half of 1995. The Company has funded and will continue
to fund its 45% portion of these infusions using proceeds from its working
capital facility.
 
    The Company's cash flow from investing activities consists of funding to and
earnings distributed to unconsolidated joint ventures, capital expenditures and
corporate acquisitions. Cash out flows to joint ventures are temporarily
financed from working capital borrowings until earning distributions are
received. Capital expenditures increased in 1994 over 1993 primarily due to the
full year effect of consolidating BDM Europe activities. In addition, the
Company expended funds to improve computer and business systems technology.
 
    Financing activities have recently centered around the Company's Credit
Facility, which was amended in May 1994, increasing the borrowing capacity to
$125 million and extending the term of the facility for one of the option years.
In April 1995, the Company exercised its second one year option to extend the
Credit Facility through July 20, 1998. Through December 31, 1995, the Company
can borrow (including letters of credit) up to the total amount of the Credit
Facility. Effective January 1, 1996, the aggregate amount of borrowing,
including outstanding letters of credit, is limited to a percentage of the
Company's eligible receivables as defined in the agreement. The Company has the
option to borrow principal at interest rates based either on the agent bank's
prime rate or LIBOR plus a margin, with unused credit also accruing a standard
interest charge. The outstanding borrowings are collateralized by a security
interest in the Company's accounts receivable. As of March 31, 1995, the Company
was eligible to borrow an additional $58.6 million and was in full compliance
with all covenants.
 
    The Company's existing sources of liquidity and working capital are expected
to continue to provide sufficient funds for the Company's operations, debt
service requirements, planned investments and capital expenditures for the
foreseeable future.

and private sector clients, including the DOD (approximately 32% of total
revenue in 1994), federal civil government clients (approximately 17% of total
revenue in 1994), foreign defense agencies (approximately 25% of total revenue
in 1994), foreign civil agencies (approximately 7% of total revenue in 1994),
state and local governments (approximately 5% of total revenue in 1994) and
commercial clients (approximately 14% of total revenue in 1994). The Company
provides its services through four decentralized subsidiaries. These
subsidiaries offer their services in specific markets using their specialized
expertise and market knowledge, while drawing upon the market access, technical
breadth and management capability of the entire BDM organization. BDM's
subsidiaries are:
 
        BDM FEDERAL: represents the evolution of a core business that dates back
    35 years, serving primarily U.S. Government clients. Included in BDM Federal
    totals, for reporting purposes, are the results recognized by GCL, an
    environmental services company acquired in 1994.
 
        BDM TECHNOLOGIES: began operations in January 1993 as part of BDM's
    evolution to a diversified company by applying its core competencies to
    serve commercial and state and local government clients.
 
        BDM EUROPE: largely consisting of a 45% interest in IABG, acquired in
    November 1993 from a company principally owned by the German Government,
    serves German and European governmental and industrial clients.
 
        VINNELL: a 63-year old company that BDM acquired in March 1992,
    specializes in international on-site operations and maintenance and training
    services in the Middle East. Additionally, Vinnell operates certain Job
    Corps Centers located in the United States for the Department of Labor.
 
  BDM FEDERAL
 
    The largest of BDM's subsidiaries, BDM Federal performs Systems and Software
Integration, Computer and Technical Services, and Enterprise Management and

  BDM EUROPE
 
    Two 1993 acquisitions make up the principal elements of BDM Europe. The
acquisition of IABG, a key component of BDM's globalization strategy, brings
important strengths to the Company in IT, technical and environmental services
and test facilities management and operation. The Company believes IABG's
prospects and opportunities in Europe are similar in scope and potential to
those BDM enjoyed in the 1980s in the United States. Environmental services, an
area of IABG specialization, offers particular growth potential, with estimates
of future expenditures in Germany and nearby states for environmental clean-up
and restoration exceeding $225 billion. BDM Europe also includes FACE, a
Netherlands-based firm experienced in information systems integration and
advanced manufacturing services. BDM Europe:
 
    . Performs environmental assessments in the former East Germany, both to
      meet requirements at contaminated sites (site inventory, investigation,
      assessment and remediation engineering) and to support environmental
      planning and the development of improved remediation systems and

      earnings from these joint ventures was approximately $1.8 million in 1994.
 
CONTRACTS
 
  TYPES OF CONTRACTS
 
    The Company's services are provided primarily through three types of
contracts: fixed-price, time-and-material and cost-reimbursable contracts.
Fixed-price contracts require the Company to perform services under the contract
at a stipulated price. Time-and-material contracts reimburse the Company for the
number of labor hours expended at established hourly rates negotiated in the
contract and the cost of materials incurred. Cost-reimbursable contracts
reimburse the Company for all actual costs incurred in performing the contract
to the extent that such costs are within the contract ceiling and allowable
under the terms of the contract, plus a fee or profit.
 
    The Company assumes greater financial risk on fixed-price type contracts
than on either time-and-material or cost-reimbursable contracts. Commercial
contracts are generally fixed-price contracts. Failure to anticipate technical
problems, estimate costs accurately or control costs during contract performance
may reduce the Company's profit or cause a loss. Greater risks are involved
under time-and-material contracts than under cost-reimbursable contracts because
the Company assumes the responsibility for the delivery of specified skills at a
fixed hourly rate. Higher profit margins are generally negotiated with the
government for fixed-price and time-and-material contracts because the Company
bears the risk that increased or unexpected costs may reduce the Company's
profit or cause a loss, while lower than anticipated costs may result in
increased profit.

  AWARD OF CONTRACTS
 
    The Company may obtain a government contract after the solicitation by the
relevant government agencies, in open and free competition, of sealed bids from
various suppliers or through the process of negotiation with the Government.
Under certain circumstances, most government agencies are authorized to enter
into contracts based on negotiation rather than sealed bids.
 
    Negotiated contracts may or may not involve the solicitation of competitive
proposals. Generally, negotiated contracts are entered into without competitive
solicitation when the services or supplies desired by the government can be
obtained from only one available source. In most non-competitive procurements,
the government solicits a proposal from the contractor and then negotiates the
price and other terms in accordance with the applicable federal regulations.
 
  GOVERNMENT CONTRACT OPERATIONS
 
    Many of the government programs in which the Company participates as a
contractor or subcontractor may extend for several years, but they are normally
funded on an annual basis. The Company's government contracts and subcontracts
are subject to modification, curtailment and termination in the event of changes
in government funding. Accordingly, all of the Company's contracts and
subcontracts involving the U.S. Government may be terminated at any time by the
U.S. Government, without cause, for the convenience of the U.S. Government. If a
U.S. Government contract is terminated for convenience, the Company would be
entitled to receive compensation for the services provided or costs incurred at
the time of termination and a negotiated amount of the profit on the contract.
 
    The Company's costs and revenue under government contracts are subject to
adjustment as a result of audits by the DCAA. Audits have been completed of
costs incurred on all years through 1987. Audits for 1988 through 1994 have not
been completed; however, management does not believe the results of these audits
will have a material effect on the Company's financial position or results of
future operations.
 
BACKLOG
 
    The Company's backlog at December 31, 1994 was approximately $1.5 billion
compared to approximately $1.3 billion at December 31, 1993. Approximately 45%
of the Company's backlog at December 31, 1994 is expected to be converted to
revenue within the current fiscal year.
 
    The Company's backlog amounts are composed of funded and unfunded
components. Funded backlog consists of the dollar portion of contracts that is
currently appropriated by the government client or other clients and allocated
to the contract by the purchasing government agency or otherwise authorized for
payment by the client upon completion of a specified portion of work. The
Company's funded backlog was approximately $535 million and $326 million as of
December 31, 1994 and December 31, 1993, respectively. Although unfunded backlog
can include up to the
 
                                       33
<PAGE>
stated award value of the contract including renewals or extensions that have
been priced but still remain at the discretion of the client whether to fund,
BDM, to be conservative, often recognizes only a portion of stated award values
on multi-year contracts into its backlog records. Because many of BDM's
contracts are multi-year contracts, total backlog may include revenue expected
to be realized several years into the future. The unfunded backlog may not be an
indicator of future contract revenue or earnings because there is no assurance
that the unfunded portion of the Company's backlog will be funded. In addition,
most of the contracts included in backlog are subject to termination for the
convenience of the government client.

MARKETING
 
    The Company's marketing activities are conducted by its professional
managers who have technical expertise and whose efforts are supplemented by the
Company's staff of engineers, scientists and analysts. The Company supports the
marketing efforts of its personnel through the direct participation of senior
management and supervisory employees. These marketing efforts are further
supported by a corporate proposal center, organized team reviews of proposals
and a formal corporate training program. The Company believes that this
marketing approach enables it to anticipate and serve the needs of its clients
and ensures that those who are seeking to obtain business for the Company have
the necessary technical expertise and resources both to develop proposals that
satisfy clients' requirements and to participate in or supervise the performance
of services that ultimately may be provided.
 
COMPETITION
 
    The information services industry in which the Company operates is highly
fragmented with no single company or small group of companies in a dominant
position. The Company's competitors include large, diversified firms with
substantially greater financial resources and larger technical staffs than the
Company as well as firms which receive preferences under set-aside programs.
Some of the Company's competitors also operate in international markets, along
with other concerns which operate exclusively or primarily outside the United
States. Some of the larger competitors offer services in a number of markets
which overlap many of the same areas in which the Company offers services, while
certain companies are focused on only one or a few of these markets. The firms
which compete with the Company are consulting firms, computer services firms,
applications software companies and accounting firms, as well as the computer
service arms of computer manufacturing companies and defense and aerospace
firms. In addition, the internal staffs of client organizations, non-profit
federal contract research centers and universities are, in effect, competitors
of the Company. The primary factors of competition in the business in which the
Company is engaged include technical, management and marketing competence, as
well as price.

EMPLOYEES AND EMPLOYEE REPRESENTATION
 
    As of March 31, 1995, the Company had approximately 7,000 full-time and
part-time employees. Joint ventures, in which the Company is a partner, employed
approximately 2,200 additional individuals as of this date. In addition, the
Company enters into agreements with a large number of consultants on a
project-specific basis who are engaged by the Company to perform specialized
work on contracts or to provide expertise in support of marketing and contract
activities. With the exception of approximately 95 Vinnell employees, no other
employees of the Company are represented by a union and, to the knowledge of the
Company, no union organizing activities are in progress.
 
    As a corporation organized under the laws of and operating in Germany, IABG
is subject to the German Co-Determination Law. Under this law, certain German
workers have a right to representation on supervisory boards of a company and,
through Workers' Councils, have a say in issues relating to corporate
operations, particularly those having a direct impact on workers. Approximately
40% of IABG's employees are covered by the tariff agreements of the German metal
workers union, IG Metall. The tariff negotiations determine the annual raises
and weekly working hours for the people covered by this tariff agreement.
Negotiations have been completed to cover the period through December 31, 1996.
 
FACILITIES
 
    The Company leases all of its offices and other facilities. The Company's
corporate headquarters are located in McLean, Virginia. The Company also leases
office buildings as principal offices in Fairfax, Virginia; Albuquerque, New
Mexico; Columbia, Maryland; Denver, Colorado; Germantown, Maryland; Kettering,
Ohio; Huntsville, Alabama; Eindhoven, The Netherlands; and Ottobrunn, Germany.
 
    In addition to these principal offices, as of March 31, 1995, the Company
maintained offices or facilities in connection with the performance of its
contracts in over 60 other locations. A portion of these premises is subleased
to others. In addition to the Company's offices and facilities, Company
personnel are frequently assigned to client locations throughout the country and
overseas.
 
    For additional information on the Company's leases and rental expenses
thereunder, see Note 17 of the Notes to Consolidated Financial Statements.
 
LEGAL PROCEEDINGS
 
    The Company is a party to various legal actions, claims, government
inquiries and audits resulting from the normal course of business. Although the
total amount of liability with respect to these matters cannot be ascertained,
the Company believes that any resulting liability should not have a material
adverse effect on the Company.

(1) Mr. Odeen joined the Company in May 1992. The bonus award shown for Mr.
    Odeen in 1992 includes a $75,000 bonus paid in connection with his
    employment with the Company, effective May 1, 1992. Mr. Woodle became an
    executive officer of the Company upon his promotion to President of Vinnell
    in June 1993. Mr. Corsiglia joined BDM Technologies in February 1993. Mr.
    Mruz resigned from the Company in August 1994.
 
(2) Bonus awards are reflected in the year to which they are attributable and
    not the year in which they are actually paid. The Company awarded cash
    bonuses and incentive compensation in the form of cash or shares of Common
    Stock to certain employees under a Cash and Stock Incentive Compensation
    Plan which was discontinued in 1992. In 1993, the Company adopted the 1993
    Executive Incentive Program (the "Executive Incentive Program"). Individual
    bonuses under the Executive Incentive Program are determined based on an
    assessment of the performance of the individual and the Company, with
    ultimate approval residing with the President, except for Mr. Odeen's bonus
    which is determined by the Compensation Committee.
 
(3) Fringe benefit amounts are omitted to the extent the aggregate value of such
    benefits is less than 10% of salary and bonus, or $50,000. The amount shown
    for Mr. Corsiglia reflects primarily reimbursement of relocation expenses.
    The amount shown for Dr. Sweeney reflects reimbursement of relocation
    expenses, and for 1994, also reflects a cost of living allowance, quarters
    allowance, and exchange rate fluctuation allowance associated with his
    overseas assignment.
 
(4) Restricted stock awards were issued pursuant to the MIS Program under which
    certain members of management were granted options to purchase Common Stock
    at an exercise price of $.01 per share. These options vest over a period
    greater than three years. The options are subject to forfeiture in the event
    certain tenure and, in part, certain Company performance criteria are not
    met. The amounts shown represent the full dollar value of the shares of
    Common Stock based on an appraised value on the date of grant, less the $.01
    per share exercise price, regardless of whether the shares were actually
    purchased. At December 31, 1994, Messrs.
 
                                       40
<PAGE>

    $1,399,000, $349,750, $1,224,125, and $69,950, respectively. The value of
    the Common Stock ownership at year-end is based on a value per share
    determined by the Board of Directors, less the $.01 per share exercise price
    paid by the named executive officer upon purchase thereof. The shares of
    restricted stock are entitled to the same dividends as all other outstanding
    shares of Common Stock. See "Dividend Policy."

(3) Because there is no established public trading market for the Common Stock,
    the Common Stock has been valued annually by an independent consulting firm
    based on a number of factors including, among others, (i) the nature of the
    business and history of the Company, the character and form of the Company's
    business and the nature of growth opportunities, (ii) the economic outlook
    in general and the condition and outlook for the specific industry in which
    the
 
                                       42
<PAGE>
    Company competes, (iii) the trend of earnings and cash flow, as recognized
    and adjusted by the Company, and future prospects for earnings and cash flow
    growth, (iv) the financial history of the Company as reflected in the
    balance sheets and operating statements over recent years, (v) the market
    history of securities and other companies in the same or similar industry,
    with attention given to various financial ratios of such companies and (vi)
    sales of the Company's stock. The values disclosed in this table are
    reflective of this valuation and a determination as to the value of the
    Common Stock by the Board of Directors.
 
MANAGEMENT INCENTIVE STOCK PURCHASE PROGRAM
 
    The Company maintains a Management Incentive Stock Purchase Program (the
"MIS Plan") providing for the issuance of options to purchase up to 1,111,111
shares of Common Stock. Since 1990 and as of March 31, 1995, the Company has
granted options ("MISOs") to certain members of management to purchase, subject
to certain vesting dates and performance goals, 1,094,169 shares of Common Stock
(net of forfeitures) at a purchase price of $.01 per share. As of March 31,
1995, options to purchase a total of 1,012,190 shares of common stock had been
exercised and options to purchase a total of 81,979 shares were outstanding.
Options to purchase a total of 16,942 shares of Common Stock remain available
for grant under the Management Incentive Stock Purchase Program.
 
    The remaining outstanding MISOs will vest on various dates between March 31,
1995 and March 31, 1997 based on tenure, and in part on the Company achieving a
specified earnings target ("Operating Profit"). Any shares that do not vest
because of the failure of the Company to achieve such Operating Profit will
subsequently vest on the first March 31 thereafter that follows a year in which
the Company achieves the target cumulative Operating Profit, provided that the
last such vesting date shall be March 31, 1997.
 
    For each of the Named Executive Officers, information regarding grants of
MISOs is listed in the Restricted Stock Awards column of the Summary
Compensation Table and information regarding the exercise of MISOs and earnings
in respect of MISOs is listed in the Aggregate Option Exercises Table.
 
1990 AND 1994 STOCK OPTION PLANS
 
    The 1990 and 1994 Stock Option Plans provide for the issuance to officers
and key employees of options to purchase up to 2,562,500 shares of Common Stock.
The options granted under the 1990 and 1994 Stock Option Plans may either
qualify as incentive stock options as defined in Section 422 of the Internal
Revenue Code of 1986, as amended (the "Code"), or, subject to the approval of
the Compensation Committee, be non-qualified options. The 1990 and 1994 Stock
Option Plans are designed to promote the interests of the Company and its
stockholders by providing selected officers and key employees with additional
incentive and opportunity to increase their proprietary interest in the Company,
thereby increasing their personal interest in its continued progress and
success. The Board of Directors may suspend or terminate the 1990 and 1994 Stock
Option Plans at any time and, subject to certain limitations, amend the 1990 and
1994 Stock Plans or any option granted thereunder, except that no amendment
requiring stockholder approval under the provisions of Section 422 of the Code
and related regulations relating to incentive stock options will be effective
without approval of the stockholders.
 
    Since 1990 and as of March 31, 1995, the Company has granted options to
purchase 1,748,932 shares of Common Stock (net of forfeitures) at an average
exercise price of $9.72 per share. As of March 31, 1995, options to purchase a
total of 251,176 shares of Common Stock had been exercised and options to
purchase a total of 1,497,756 shares of Common Stock were outstanding.
 
                                       43
<PAGE>
    On May 5, 1995, the Company granted the remaining 16,942 options pursuant to
the MIS Plan and an additional 8,058 of options identical to those under the MIS
Plan at an exercise price of $.01 per share and 32,500 options pursuant to the
1994 Stock Option Plan at an exercise price of $17.25 per share.
 
    In addition, prior to consummation of the Offerings, the Company intends to
adopt, subject to obtaining all necessary approvals, the 1995 Employee Stock
Purchase Plan (the "1995 Plan"). The 1995 Plan permits the granting of rights to
purchase a maximum of 750,000 shares of Common Stock, subject to adjustments.
The 1995 Plan authorizes the Company and such of its subsidiaries as the Board
of Directors may designate to offer employees the right to purchase, through
payroll deductions, shares of Common Stock in monthly intervals at a purchase
price equal to the lower of 85% of the fair market value of the Common Stock on
the offering date or 85% of the fair market value of the Common Stock at the end
of each month during the purchase period.
 
    Information regarding grants of stock options, the exercise of options and
earnings in respect of options is provided in the tables for Named Executive
Officers of the Company named in the Summary Compensation Table.
 
BDM RETIREMENT PLAN
 
    The BDM Retirement Plan (the "Retirement Plan") is a defined benefit plan
funded entirely by the Company. The retirement benefit formula, coupled with
expected benefits from Social Security, is designed to provide a defined level
of income during retirement. All employees of BDM Federal and BDM Technologies
who complete a specified number of hours of employment in a plan year are
eligible to participate in the Retirement Plan. Under the Retirement Plan, the
normal retirement age is 60. Employees are eligible for early retirement at age
55 if they have completed 24 months of active, regular, full-time employment.
Participants in the Retirement Plan are generally entitled upon retirement to a
benefit equal to the sum of (a) for each year of benefit accrual service for
plan years after December 25, 1989, 1.4% of annual compensation up to the
35-year average of the social security-covered compensation (rounded to the
nearest $600) plus 1.82% of annual compensation in excess of the 35-year average
of the social security-covered compensation (rounded to the nearest $600), and
(b) 1.33% of average annual compensation up to the 35-year average of the social
security-covered compensation for 1989, plus 2% of the average annual
compensation in excess of the 35-year average of the social security-covered
compensation for 1989 multiplied by the number of years of benefit accrual
service for plan years prior to December 26, 1989. The maximum number of years
of benefit accrual service allowed in making the calculation is 20.
 
    The Company intends to supplement the benefit payment under the Retirement
Plan on behalf of Messrs. Odeen and Woodle through a defined contribution SERP.
An annual contribution will be credited to accounts established in the Company
for Messrs. Odeen and Woodle in the amounts of $57,223 and $44,000,
respectively, which are expected to provide an actuarially determined benefit
when Messrs. Odeen and Woodle reach the age of 65, that, when combined with the
benefits from the Company's retirement plans, will equal $90,000.
 
    The Company intends to supplement the benefit payment to Dr. Sweeney and Mr.
Corsiglia under the Retirement Plan through a defined benefit SERP to the extent
necessary to ensure that such individuals who retire on or after their normal
retirement age with 20 or more years of benefit service receive a stated target
retirement benefit of 45% of average compensation for the five highest
consecutive years of such individuals' employment.
 
    The years of benefit accrual service under the Retirement Plan and the
estimated maximum anticipated annual benefits at normal retirement date for the
Named Executive Officers participating in the Retirement Plan, as of December
31, 1994, are presented in the table below. The estimated maximum anticipated
annual benefits at normal retirement date for each of such officers who are
 
                                       44
<PAGE>
participants in the SERP as of December 31, 1994 are also presented. In
calculating benefits at retirement, annual earnings have been estimated based on
no escalation of current plan year earnings. Benefit payments may be subject to
a legislated ceiling at the time of retirement.

EMPLOYMENT AGREEMENTS
 
    Philip A. Odeen became President and Chief Executive Officer of the Company
on May 1, 1992. Pursuant to a letter agreement, dated March 4, 1992, Mr. Odeen
is paid a base annual salary of $400,000. Should Mr. Odeen's employment with the
Company be terminated prior to December 31, 1995, he will receive a separation
allowance in the amount of 24 months' salary.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    For fiscal years 1991 through 1994, the Compensation Committee of the Board
of Directors made all determinations with respect to executive officer
compensation. Messrs. Carlucci, Conway and Slosar, each a Director of the
Company, served as members of the Compensation Committee in 1994. The Company is
not aware of any Compensation Committee interlocks.
 
    Messrs. Carlucci and Conway are Chairman and Vice Chairman of the Company,
respectively, stockholders of the Company and Managing Directors of Carlyle. Mr.
Conway owns more than 10% of the capital stock of the general partner of
Carlyle. Carlyle is the general partner of The Carlyle Fund, BDM Partners and
BDM Acquisition II, stockholders of the Company.
 
    The Company has retained Carlyle to provide certain financial and
investor-relations services, to assist management in evaluating corporate
acquisition opportunities and financial strategies and to provide other similar
services. In consideration of such services, the Company will pay Carlyle an
annual fee of $500,000 plus expenses, a portion of which is offset by the amount
which ordinarily would be payable to Mr. Conway for services rendered in his
capacity as a Director of the Company. In addition, although no definitive
agreement has been executed, it is currently anticipated that Carlyle will serve
as a financial advisor to the Company in connection with any acquisition,
corporate reorganization, financing, stock offering or similar transaction by
the Company, and will receive fees commensurate with its services in connection
with any such transaction. However, Carlyle has waived its rights to receive a
financial advisory fee in connection with the Offerings. The Company paid
Carlyle approximately $505,000, $535,000 and $512,000 for the provision of these
services for the years ended December 31, 1994, 1993 and 1992, respectively. In
addition, in connection with the acquisition of Vinnell in 1992, Carlyle
received from the Company an advisory fee of $250,000, plus expenses.

                              CERTAIN TRANSACTIONS
 
1990 ACQUISITION
 
    An investor group led by Carlyle and certain members of management acquired
the business and assets of the Predecessor Company for a total cash
consideration of approximately $118 million, subject to the assumption of a
substantial portion of the liabilities of the Predecessor Company and to
adjustment based on an arbitration process instituted to determine the net worth
of the Predecessor Company on the acquisition date. In August 1991, the results
of the arbitration process determined an increase in net worth of the
Predecessor Company of approximately $8.5 million, for a final purchase price of
approximately $126.5 million, excluding approximately $7 million in transaction
expenses. The purchase price and related transaction expenses were financed by
the Company through various sources commonly relied on in leveraged transactions
led by management and outside investors, namely $30 million in cash provided in
exchange for Common Stock purchased by certain investors pursuant to the
Investor Agreement; senior secured borrowings of $80.5 million under a prior
credit facility; $10 million in cash received from Carlyle as the purchase price
of 100,000 shares of Series A Preferred Stock (the "Series A Preferred Stock");
and $13 million provided by Loral Aerospace Corporation ("LAC"), a subsidiary of
Loral, as the purchase price for a subordinated promissory note (the
"Subordinated Note") and a subordinated conditional note (the "Conditional
Note"), each due October 23, 1997, issued by the Company. The increase in the
final purchase price for the Predecessor Company was added to the amount due on
the subordinated promissory note, retroactive to October 23, 1990, with interest
at an annual rate of 12%. In July 1993, the Company repaid the Subordinated
Note. In October 1994, the Conditional Note expired.
 
    In connection with the 1990 Acquisition, the Company paid a financial
advisory fee to Carlyle in the amount of approximately $1.6 million, which
amount is included in the transaction expenses of approximately $7 million
incurred by the Company.
 
    Messrs. Carlucci and Conway are Chairman and Vice Chairman of the Company,
respectively, stockholders of the Company and Managing Directors of Carlyle. Mr.
Conway owns more than 10% of the capital stock of the general partner of
Carlyle. Carlyle is the general partner of The Carlyle Fund, BDM Partners and
BDM Acquisition II, stockholders of the Company.
 
    The Company has retained Carlyle to provide certain financial and

addition, in connection with the acquisition of Vinnell in 1992, Carlyle
received from the Company an advisory fee of $250,000, plus expenses.
 
    All future transactions (other than ordinary course transactions such as
fixing salaries or awarding employee benefits) and loans between the Company and
its directors, officers and principal stockholders will be ratified by a

ACQUISITION OF VINNELL
 
    In March 1992, the Company acquired the outstanding stock of Vinnell for
approximately $29.6 million. The seller of such stock is presently a member of
the Board of Directors of Vinnell. In connection with the acquisition of
Vinnell, the Company guaranteed a subordinated promissory note due March 13,
1996 issued by Vinnell to the seller in the principal amount of $3.7 million at
an annual rate of interest of 10%. Interest on the note is payable
semi-annually, and the principal amount is due on the earlier of March 13, 1996,
or six months after the death of the seller. The note was issued in
consideration for the seller's agreement not to engage in or associate with any
business in competition with Vinnell or employ any employee or consultant of
Vinnell until March 13, 1996 with respect to the United States and countries in
which Vinnell has entered into contracts to provide services or sell supplies
within three years prior to March 13, 1992 or in which Vinnell conducts or seeks
to conduct business. The Company intends to prepay this note with the proceeds
of the Offerings. The Company also entered into a consulting agreement with the
seller for a term of five years providing for the payment of $250,000 in 1992
and $200,000 in each of 1993 through 1996 for the performance of consulting
services by the seller in each of such years.
 
RECENT STOCKHOLDER TRANSACTIONS
 
    In April 1991, The Carlyle Fund purchased 1,500,000 shares of Common Stock
from the Company at a purchase price of $4.00 per share. The Company used a
portion of the net proceeds of the 1991 Offering and the sale to the Carlyle
Fund to redeem the Series A Preferred Stock issued to Carlyle for $10 million
(representing the purchase price at the time of their issuance), plus accrued
dividends. The dividends payable upon redemption included an amount equal to the
expenses incurred by Carlyle in acquiring the Series A Preferred Stock plus
interest on such expenses at an annual rate of 12%.
 
    In May 1991, the Company sold 500,000 additional shares of Common Stock at a
purchase price of $4.00 per share to The Carlyle Fund. The proceeds were used to
pay down the Company's outstanding revolving line of credit under a prior credit
facility.
 
    The Company acquired from the Richard King Mellon Foundation ("Mellon")
100,000 shares of Common Stock at $8.00 per share in July 1993 and 100,000
shares of Common Stock at $12.00 per share in March 1994. The Company has
reserved such shares for issuance to employees under the Employee Stock Purchase
Plan.
 
    On May 27, 1994, the Company acquired 2,250,000 shares and 350,000 shares of
its outstanding Common Stock and Class B Common Stock, respectively, from the
Investor Group (as defined herein) for its then fair value of $14.00 per share.
 
INVESTOR AGREEMENT
 
    On October 23, 1990, The Carlyle Fund, Mellon, Equitable Capital Private
Income and Equity Partnership, II, L.P. ("Equitable Partnership") and Equitable
Deal Flow Fund, L.P. ("Equitable Fund") (collectively, the "Investor Group")
entered into the Investor Agreement with the Company which contains certain
provisions with respect to the transfer of shares of Common Stock by the
Investor Group. As a result of the sale of Common Stock by The Carlyle Fund to
BDM Acquisition II, BDM Partners, the Board of Regents of The University of
Texas System, as trustee of The University of Texas System Common Trust Fund
(the "Board of Regents") and the Permanent University Fund of The State of Texas
(the "Permanent University Fund"), such parties (together with the Investor
Group, the "Principal Stockholders") became subject to the Investors Agreement.
 
    Pursuant to the terms of the Investor Agreement, if an Investor Group
member, or a transferee of a member pursuant to a transaction not involving a
public offering or an offering not made pursuant to Rule 144 under the
Securities Act (a "Transferee"), desires to sell any shares of Common Stock
purchased under the Investor Agreement other than (i) to another Investor Group
member, the Company or an affiliate, (ii) to a prospective purchaser in a
transaction made pursuant
 
                                       47
<PAGE>
to an effective registration statement or (iii) pursuant to Rule 144 under the
Securities Act or pursuant to certain pledges, grants of security interests or
other encumbrances effected by an Investor Group member or Transferee with
respect to its shares of Common Stock (an "Exempt Transaction"), then the
Company and the other Investor Group members have the right (a "first refusal"
right) to purchase all, but not less than all, of those shares on the same terms
and conditions as those offered by the prospective purchaser. Additionally, if
an Investor Group member desires to transfer shares purchased under the Investor
Agreement and such transfer, together with all previous transfers made by such
member (excluding Exempt Transactions), would exceed an aggregate of 20% of the
shares of Common Stock originally held by such member, then the other Investor
Group members have the right (a "tag-along right") to include in the proposed
transfer, at the same price and on the same terms and conditions, a certain
percentage of the shares then held by the other Investor Group members (on a
fully diluted basis). Further, if one or more Investor Group members and/or
other holders of Common Stock desire to transfer (other than in an Exempt
Transaction) 50% or more of the then outstanding Common Stock (on a fully
diluted basis), then such members and/or other holders have the right (a
"bring-along right") to require all Investor Group members to offer a certain
percentage of their Common Stock to the prospective purchaser on the same terms
as those that the proposed selling members and/or other holders are willing to
accept. Upon consummation of the Offerings, the tag-along and bring-along rights
will terminate.
 
    Any transferee of shares of Common Stock held by the Investor Group pursuant
to the exercise of first refusal or tag-along rights (other than a transferee
pursuant to an Exempt Transaction) is required to agree to be subject to all of
the obligations under the Investor Agreement (including the first refusal
provisions contained therein) and the Stockholders Agreement. See
"--Stockholders Agreement." Such transferee is also entitled to all the various
rights of the Investor Group under the Investor Agreement, including the first
refusal, piggy-back and demand registration rights. For a discussion of the
piggy-back and demand registration rights of the parties subject to the Investor
Agreement, see "Shares Eligible for Future Sale--Registration Rights."
 
STOCKHOLDERS AGREEMENT
 
    On October 23, 1990, the Company, Carlyle, the Investor Group and certain
Management Representatives entered into a Stockholders Agreement, dated October
23, 1990 (the "Stockholders Agreement"), which contains various provisions with
respect to the governance and operations of the Company. As a result of the sale
of Common Stock by The Carlyle Fund to BDM Acquisition II, BDM Partners, the
Board of Regents and the Permanent University Fund, such parties became subject
to the Stockholders Agreement.
 
    The Stockholders Agreement, as amended, provides that the stockholders
subject thereto will vote their shares as follows: seven directors designated by
Carlyle, five directors designated by the Management Representatives and three
independent directors designated jointly by Carlyle and the Management
Representatives; however, by action of the Board of Directors, the number of
directors is currently fixed at 13. Such stockholders are therefore able to
control the outcome of all matters submitted to a vote of the Company's
stockholders, as well as the Company's management, operations and policies.
Actions taken to remove or replace a particular director may be taken only by
the particular stockholders entitled to nominate such director (and, in the case
of the independent directors, by both Carlyle and the Management
Representatives).
 
    The Stockholders Agreement also imposes requirements for approval by at
least eight directors of the Company for certain fundamental corporate
transactions, amendments to the Certificate of Incorporation or By-laws
materially altering the rights of holders of Common Stock and the filing of a
registration statement under the Securities Act with respect to an underwritten
primary public offering of Common Stock of the Company.
 
    Upon consummation of the Offerings, the Stockholders Agreement will
terminate.

                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
    The authorized Common Stock of the Company consists of 50,000,000 shares of
Common Stock, 2,000,000 shares of Class B Common Stock and 500,000 shares of
preferred stock, par value $.01 per share (the "Preferred Stock"). As of March
31, 1995, there were 765 holders of record of Common Stock and two holders of
Class B Common Stock. Upon completion of the Offerings, there will be 11,575,656
shares of Common Stock outstanding and 400,000 shares of Class B Common Stock
outstanding. As of March 31, 1995, options were exercisable for 838,607 shares
of Common Stock.
 
    Preferred Stock may be issuable in one or more series from time to time at
the discretion of the Board of Directors. The Board of Directors is authorized
to establish the number of shares to be included in each series and fix the
respective designations, powers, preferences, rights, qualifications,
restrictions and limitations of each series. The issuance of Preferred Stock
could be used as an "anti-takeover" device without requiring further action on
the part of the holders of the Common Stock or the Class B Common Stock. The
Company has no current plans to issue another series of the Preferred Stock.
 
    The following is a summary of certain of the detailed provisions of the
Certificate of Incorporation regarding the capital stock of the Company. Such
summary is not complete and is qualified in its entirety by reference to the
Certificate of Incorporation and to the By-laws, copies of which are filed as
exhibits to the Registration Statement of which this Prospectus is a part.
 
COMMON STOCK AND CLASS B COMMON STOCK
 
    The holders of Common Stock are entitled to one vote per share for each
share held of record in elections for directors and on all other matters
required or permitted to be approved by a vote of stockholders of the Company.
Each share of the Common Stock and each share of the Class B Common Stock are
equal in respect of rights in liquidation and rights to dividends or
distributions, except that in the case of dividends or other distributions
payable in securities of the Company, only non-voting securities will be
distributed with respect to the Class B Common Stock.
 
    The Class B Common Stock is non-voting except with respect to matters for
which class voting is required by the DGCL. The Company is required to convert
any shares of Class B Common Stock into shares of Common Stock upon the
disposition of such shares by the holder thereof as part of: (1) a sale of all
or substantially all of the Common Stock of the Company; (2) a merger or
consolidation of the Company in which the stockholders of the Company receive
cash and/or marketable securities in exchange for their stock; (3) an
underwritten public offering of Common Stock of the Company pursuant to a
registration statement filed with, and declared effective by, the SEC (other
than a registration statement filed in connection with an employee benefit
offering or a merger or acquisition, or an offering of securities in connection
with an exchange offer or solely to existing security holders of the Company or
present and former employees of the Company or consultants or independent
contractors performing substantial services for the Company); (4) a sale
pursuant to Rule 144 under the Securities Act, following a public offering as
described above; or (5) any other transaction if the conversion of the Class B
Common Stock has been approved by a majority of the Board of Directors of the
Company.
 
    Stockholders of the Company do not and will not have any preferential or
preemptive rights to subscribe for, purchase or receive additional shares of any
class of capital stock of the Company, or any options or warrants for such
shares, or any rights to subscribe for or purchase such shares, or any
securities convertible into or exchangeable for such shares, which may be
issued, sold or offered for sale by the Company.
 
                                       51
<PAGE>
PREFERRED STOCK
 
    The Company's Board of Directors has the authority, without further
stockholder approval, to provide for the issuance of up to 500,000 shares of
Preferred Stock in one or more series, to establish the number and designation
of shares to be included in each series, and to determine the dividend rights,
conversion rights, voting rights, rights and terms of redemption and liquidation
or dissolution rights of such shares. Because the Board of Directors has the
power to establish the preferences and rights of each series, it may afford the
holder of any Preferred Stock preferences, powers and rights (including voting
rights) senior to the rights of the holders of common stock. No shares of
Preferred Stock are currently outstanding. Although the Company currently has no
intention to issue Preferred Stock, the issuance of shares of Preferred Stock or
the issuance of rights to purchase such shares, may have the effect of delaying,
deferring or preventing a change in control of the Company.
 
CERTAIN EFFECTS OF AUTHORIZED BUT UNISSUED STOCK
 
    Upon completion of the Offerings, the Company's authorized but unissued
capital stock will consist of 38,424,344 shares of Common Stock, 1,600,000
shares of Class B Common Stock and 500,000 shares of Preferred Stock. All of the
foregoing authorized but unissued shares of capital stock will be available for
future issuance without stockholder approval. These additional shares may be
utilized for a variety of corporate purposes, including issuance pursuant to
stock options granted to certain members of management and key employees and
other employee plans, and future public offerings to raise additional capital or
to facilitate corporate acquisitions.
 
    The Company does not presently have any plans to issue additional shares of
Common Stock other than shares of Common Stock which may be issued upon exercise
of existing options or options which may be granted in the future under the
Management Incentive Stock Purchase Program, the 1990 Stock Option Plan or the
1994 Stock Option Plan.
 
TRANSFER AGENT AND REGISTRAR
 
    Wachovia Bank of North Carolina, N.A. serves as the Transfer Agent and
Registrar for the Common Stock.

<PAGE>
                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Upon the completion of the Offerings, the Company will have 11,975,656
shares of Common Stock and Class B Common Stock outstanding. Of these shares,
the 2,500,000 shares of Common Stock sold in the Offerings, the 1,339,217 shares
of Common Stock sold in the 1991 Offering and the 1,562,500 shares of Common
Stock issued, or to be issued, upon exercise of stock options granted under the
1990 Option Plan that have been registered under the Securities Act pursuant to
registration statements on Form S-8 will be freely tradable without restriction
under the Securities Act by persons other than "affiliates" of the Company
without restriction under the Securities Act. In addition, the Company currently
intends to register the shares of Common Stock under the 1994 Stock Option Plan
pursuant to which options to purchase 186,432 shares have been granted. If
registered, such shares will be freely tradable as described above. An
additional 360,000 shares of Common Stock are reserved for issuance under the
Company's Employee Stock Purchase Plan (the "Employee Stock Purchase Plan") of
which 231,748 shares had been issued as of March 31, 1995, and will be freely
tradable without restriction under the Securities Act when issued. The remaining
7,653,515 shares of issued and outstanding Common Stock were acquired in
transactions that were exempt from registration under the Securities Act and
consequently may not be resold unless they are registered under the Securities
Act or are sold pursuant to an applicable exemption from registration, including
Rule 144 under the Securities Act.
 
    In general, under Rule 144 as presently in effect, if a period of at least
two years has elapsed since the later of the date the "restricted shares" (as
that phrase is defined in Rule 144) were acquired from the Company and the date
they were acquired from an "affiliate" (as that term is defined in Rule 144) of
the Company, as applicable, then the holder of such restricted shares (including
an affiliate) is entitled to sell a number of shares within any three-month
period that does not exceed the greater of 1% of the then outstanding shares of
the Common Stock (approximately 120,000 shares immediately after the
consummation of the Offerings, assuming the over-allotment options are not
exercised) or the average weekly trading volume reported by the Nasdaq National
Market in the Common Stock during the four calendar weeks preceding such sale.
The holder may only sell such shares through unsolicited brokers' transactions.
Sales under Rule 144 are also subject to certain requirements pertaining to the
manner of such sales, notices of such sales and the availability of current
public information concerning the Company. Affiliates may sell shares not
constituting restricted securities in accordance with the foregoing volume
limitations and other requirements but without regard to the two-year period.
 
    Under Rule 144(k), if a period of at least three years has elapsed since the
later of the date restricted shares were acquired from the Company and the date
they were acquired from an affiliate of the Company, as applicable, then a
holder of such restricted shares who is not an affiliate of the Company at the
time of the sale and who has not been an affiliate of the Company for at least
three months prior to the sale would be entitled to sell the shares immediately
without regard to the volume limitations and other conditions described above.
 
    The Company has filed two registration statements on Form S-8 under the
Securities Act to register the shares of Common Stock reserved for issuance
under the 1990 Stock Option Plan and the Employee Stock Purchase Plan. The
Company intends to file an additional registration statement on Form S-8 under
the Securities Act to register the shares of Common Stock reserved for issuance
under the 1994 Stock Option Plan. Shares registered pursuant to such
registration statements are freely tradable except to the extent that the
holders thereof are deemed to be "affiliates" of the Company, in which case the
transferability of such shares will be subject to the volume limitations set
forth in Rule 144 under the Securities Act.
 
    The Company, the Principal Stockholders and certain directors and executive
officers have agreed that during the period beginning on the date of this
Prospectus and continuing to and
 
                                       53
<PAGE>
including the date 180 days after the date of this Prospectus, not to offer,
sell, contract to sell or otherwise dispose of any shares of Common Stock or any
securities of the Company which are substantially similar to the Common Stock,
including securities which are convertible into or exchangeable for, or
represent the right to receive, Common Stock or any such substantially similar
securities (other than pursuant to employee stock option plans, employee stock
purchase plans or 401(k) plans existing on the date of this Prospectus or in an
acquisition in which the person or persons receiving the Common Stock or
substantially similar securities agree in writing to be bound by this clause)
without the prior written consent of the representatives of the Underwriters
except for the shares of Common Stock offered in connection with the concurrent
U.S. and international offerings.
 
    As of March 31, 1995, the Company had reserved 1,579,735 shares of Common
Stock for issuance upon exercise of outstanding stock options and 830,510 shares
of Common Stock for issuance upon exercise of future option grants.
 
    Prior to the Offerings, there has been no public market for the Common
Stock. The Company can make no predictions as to the effect, if any, that sales
of shares of Common Stock or the availability of shares of Common Stock for sale
will have on the market price prevailing from time to time. Nevertheless, sales
of substantial amounts of the Common Stock in the public market, or the
perception that such sales may occur, could adversely affect prevailing market
prices.
 
REGISTRATION RIGHTS
 
    Pursuant to the Investor Agreement, upon completion of the Offerings, the
stockholders who are subject thereto have registration rights with respect to
6,700,000 shares of Common Stock. Such stockholders have the right, subject to
certain exceptions in the case of an underwritten public offering, to include
their shares in any registration statement relating to Common Stock (or other
securities) filed by the Company under the Securities Act. Once the Common Stock
is traded on the Nasdaq National Market, Investor Group members and transferees
of their shares of Common Stock (pursuant to transactions that are not Exempt

    Under the terms and conditions of the Underwriting Agreement, the U.S.
Underwriters are committed to take and pay for all of the shares offered hereby,
if any are taken.
 
    The U.S Underwriters propose to offer the shares of Common Stock in part
directly to the public at the public offering price set forth on the cover page
of this Prospectus and in part to certain securities dealers at such price less
a concession of $       per share. The U.S. Underwriters may allow, and such
dealers may reallow, a concession not in excess of $       per share to certain
brokers and dealers. After the shares of Common Stock are released for sale to
the public, the offering price and other selling terms may from time to time be
varied by the representatives.
 
    The Company has entered into an underwriting agreement (the "International
Underwriting Agreement") with the underwriters of the International Offering
(the "International Underwriters") providing for the concurrent offer and sale
of 500,000 shares of Common Stock in an international offering outside of the
United States. The offering price and aggregate underwriting discounts and
commissions per share for the two offerings are identical. The closing of the
offering made hereby is a condition to the closing of the International
Offering, and vice versa. The representatives of the International Underwriters
are Goldman Sachs International and Lehman Brothers International (Europe).
 
    Pursuant to an Agreement between the U.S. and International Underwriting
Syndicates (the "Agreement Between") relating to the two offerings, each of the
U.S. Underwriters has agreed that, as a part of the distribution of the shares
offered hereby and subject to certain exceptions, it will offer, sell or deliver
the shares of Common Stock, directly or indirectly, only in the United States of
America (including the States and the District of Columbia), its territories,
its possessions and other areas subject to its jurisdiction (the "United
States") and to U.S. persons, which term shall mean, for purposes of this
paragraph: (a) any individual who is a resident of the United States or (b) any
corporation, partnership or other entity organized in or under the laws of the
United States or any political subdivision thereof and whose office most
directly involved with the purchase is located in the United States. Each of the
International Underwriters named herein has agreed pursuant to the Agreement
Between that, as a part of the distribution of the shares offered as a part of
the International Offering, and subject to certain exceptions, it will (I) not,
directly or indirectly, offer, sell or deliver shares of Common Stock (a) in the
United States or to any U.S. persons or (b) to any person who it believes
intends to reoffer, resell or deliver the shares in the United States or
 
                                       55
<PAGE>
to any U.S. persons, and (ii) cause any dealer to whom it may sell such shares
at any concession to agree to observe a similar restriction.
 
    Pursuant to the Agreement Between, sales may be made between the U.S.
Underwriters and the International Underwriters of such number of shares of
Common Stock as may be mutually agreed. The price of any shares so sold shall be
the initial public offering price, less an amount not greater than the selling
concession.
 
    The Company has granted the U.S. Underwriters an option exercisable for 30
days after the date of the Prospectus to purchase up to an aggregate of 300,000
additional shares of Common Stock solely to cover over-allotments, if any. If
the U.S. Underwriters exercise their over-allotment option, the U.S.
Underwriters have severally agreed, subject to certain conditions, to purchase
approximately the same percentage thereof that the number of shares to be
purchased by each of them, as shown in the foregoing table, bears to the
2,000,000 shares of Common Stock offered hereby. The Company has granted the
International Underwriters a similar option exercisable up to an aggregate of
75,000 additional shares of Common Stock.
 
    The Company, the Principal Stockholders and certain directors and executive
officers have agreed that during the period beginning from the date of this
Prospectus and continuing to and including the date 180 days after the date of
the Prospectus, not to offer, sell, contract to sell or otherwise dispose of any
shares of Common Stock or any securities of the Company which are substantially
similar to the shares of Common Stock, including but not limited to securities
which are convertible into or exchangeable for, or represent the right to
receive, Common Stock or any such substantially similar securities (other than,
with respect to the Company, pursuant to employee stock option plans, employee
stock purchase plans, 401(k) plans or any other employee plans of similar
nature, including, without limitation, any such plans for the benefit of
directors or officers of the Company, which are described in this Prospectus or
in an acquisition in which the person or persons receiving the Common Stock or
substantially similar securities agree in writing to be bound by such clause)
without the prior written consent of the representatives, except for the shares
of Common Stock offered in connection with the concurrent U.S. and international
offerings.
 
    The representatives of the Underwriters have informed the Company that they
do not expect sales to accounts over which the Underwriters exercise
discretionary authority to exceed five percent of the total number of shares of
Common Stock offered by them.
 
    Prior to the offerings, there has been no public market for the shares. The
initial public offering price will be negotiated among the Company and the
representatives of the U.S. Underwriters and the International Underwriters.
Among the factors to be considered in determining the initial public offering
price of the Common Stock, in addition to prevailing market conditions, are the
Company's historical performance, estimates of the business potential and
earnings prospects of the Company, an assessment of the Company's management and
the consideration of the above factors in relation to market valuation of
companies in related businesses.
 
    Application has been made for the Common Stock to be approved for quotation
and trading on the Nasdaq National Market under the symbol "BDMI."
 
    The Company has agreed to indemnify the several Underwriters against certain
liabilities, including liabilities under the Securities Act.
 
                            VALIDITY OF COMMON STOCK
 
    The validity of the Common Stock offered hereby will be passed upon for the
Company by Willkie Farr & Gallagher, New York, New York, and for the U.S.
Underwriters by Sullivan & Cromwell, Washington, D.C.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
The Board of Directors and Stockholders
  BDM International, Inc.
 
    We have audited the accompanying consolidated balance sheets of BDM
International, Inc. and Subsidiaries (the Company) as of December 31, 1994 and
1993, and the related consolidated statements of operations, stockholders'
equity and cash flows for each of the three years in the period ended December
31, 1994. 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 consolidated financial position of
BDM International, Inc. and Subsidiaries as of December 31, 1994 and 1993, and
the consolidated results of their operations and their cash flows for each of
the three years in the period ended December 31, 1994, in conformity with
generally accepted accounting principles.
 
    As discussed in Note 10 to the consolidated financial statements, effective
as of the beginning of 1992, the Company changed its method of accounting for
income taxes to conform with Statement of Financial Accounting Standards No.

1. ORGANIZATION
 
    BDM International, Inc. (BDM or Company) was privately owned from its
inception in 1959 until 1980, when it became a publicly owned company. BDM was
purchased by and became a wholly-owned subsidiary of Ford Aerospace Corporation
(Ford Aerospace) in June 1988. BDM remained a wholly-owned subsidiary of Ford
Aerospace until members of senior management and an investor group led by The
Carlyle Group, L.P. (Carlyle), a private merchant banking firm, acquired
substantially all of the assets, liabilities and business of BDM on October 23,
1990.
 
    BDM is a multinational information technology company that operates
primarily in three interrelated markets: Systems and Software Integration,
Computer and Technical Services and Enterprise Management and Operations. The
Company serves governmental and commercial clients both domestically and abroad.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Principles of Consolidation
 
    The consolidated financial statements include all majority-owned or
controlled subsidiaries and joint ventures of the Company. All significant
intercompany accounts and transactions have been eliminated. The Company's
earnings in unconsolidated joint ventures are accounted for using the equity
method.
 
  Unaudited Information
 
    Financial information for the three months ended March 31, 1995 and 1994 are
unaudited but have been prepared on the same basis as the audited consolidated
financial statements and, in the opinion of management, contain all adjustments
necessary for a fair presentation of the financial position, result of 
operations, and cash flows for such periods. The consolidated results of 
operations for the three months ended March 31, 1995 are not necessarily
indicative of the results to be expected for any future period.
 
  Revenue Recognition
 
    The Company's revenue is derived primarily from long-term contracts of
various types. Revenue on cost-reimbursable contracts is recognized to the
extent of costs incurred plus a proportionate amount of the fee. Revenue on
fixed-price contracts is recognized using the percentage-of-completion method
based on the relationship of actual costs incurred to total costs estimated to
be incurred over the duration of the contract. Revenue on time-and-material
contracts is recognized based on actual hours delivered at the contracted hourly
rate plus the cost of any materials incurred. The fees under certain U.S.
Government contracts may be increased or decreased in accordance with cost or
performance incentive provisions which measure actual performance against
established targets or other criteria. Such incentive fee awards or penalties
are included in sales at the time the amounts can be reasonably determined.
Provisions for anticipated contract losses are recognized at the time they
become known.
 
    Progress payments received in advance from customers are applied first to
any amount of unbilled accounts receivable of related contracts. Any excess of
the payments received in advance over the related unbilled accounts receivable
is recorded as an advance payment liability.

  (INFORMATION AS OF AND FOR THE THREE MONTHS ENDED MARCH 31, 1995 AND 1994 IS
                                   UNAUDITED)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)
  Foreign Currency Translation
 
    The results of operations from foreign subsidiaries are translated to U.S.
dollars using the average exchange rates during the period. Assets and
liabilities are translated to U.S. dollars at the exchange rate in effect at the
balance sheet date. The resulting cumulative translation adjustments are
reflected in stockholders' equity.
 
  Statements of Cash Flows
 
    Effective in 1993, and as permitted and preferred by the Statement of
Financial Accounting Standard No. 95--Statement of Cash Flows, the Company
changed its method of reporting cash flows to the direct method. The Statements
of Cash Flows for all periods included herein have been restated to conform to
the direct method presentation.
 
    Cash flows from the operations of the Company's foreign subsidiaries are
calculated based on their reporting currencies. The effect of exchange rate
changes on the cash balances held in foreign currencies is reported separately
in the Statements of Cash Flows.
 
    The Company considers all highly liquid financial instruments with purchased
maturities of three months or less to be cash equivalents.
 
  Property and Equipment
 
    Property, equipment and furniture are recorded at cost, or assigned fair
value if acquired through an acquisition. Furniture and equipment are
depreciated over their estimated useful lives, ranging from three to ten years,
primarily using the declining balance method. Leasehold improvements are
amortized over their estimated useful lives or lease terms, whichever is
shorter, using the straight-line method. Maintenance and repairs are charged to
expense as incurred.
 
  Goodwill and Intangible Assets
 
    Goodwill represents the excess of the cost of acquiring businesses over the
fair value of identifiable net tangible and intangible assets acquired. Goodwill
is amortized on a straight-line basis over the period for which the Company
estimates it will benefit directly from the acquisition. Although the period of
benefit from a goodwill asset can be difficult to estimate, the Company
considers a goodwill asset to be recoverable as long as the acquisition
generates positive cash flow from operations after implementation of the
Company's strategic plan or completion of reorganization efforts, if any.
Recoverability of individual goodwill assets is evaluated periodically based on
current undiscounted cash flow projections of each specific acquired business.
To date, the Company has limited the period of amortization of any individual
goodwill asset to fifteen years, even though most of the Company's acquisitions
would project positive cash flows from operations for a much longer period.
Goodwill is currently being amortized over periods ranging from five to fifteen
years.
 
    Intangible assets are recorded at cost, or assigned fair value if acquired
through a business acquisition. Intangible assets are amortized on a
straight-line basis over the term of the underlying asset or the estimated
period of benefit, currently ranging from three to five years, or in the case of
contract backlog, over the remaining terms of the acquired contracts in relation
to the recognition of related contract revenue.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)
  Research and Development Costs
 
    Research and development costs are expensed as incurred and are included in
selling, general and administrative costs. Research and development costs
amounted to $0.5 million and $2.4 million for the three months ended March 31,
1995 and 1994 and $7.1 million, $7.8 million and $1.2 million for the years
ended December 31, 1994, 1993 and 1992.
 
  Income Taxes
 
    Effective January 1, 1992, the Company adopted the provisions of Statement
of Financial Accounting Standard No. 109--Accounting for Income Taxes (SFAS
109). SFAS 109 requires a company to recognize deferred tax assets and
liabilities for the expected future tax consequences of events that have been
recorded in a company's financial statements or tax returns. Deferred tax assets
and liabilities represent the tax effects of differences between the financial
statement carrying amounts and the tax basis carrying amounts of the Company's
assets and liabilities. These differences are calculated based upon the
statutory tax rates in effect in the years in which the differences are expected
to reverse. The effect of subsequent changes in tax rates on deferred tax
balances is recognized in the period in which a tax rate change is enacted.
 
    Foreign income taxes that are reimbursable pursuant to the contracts
generating the foreign income are classified as contract costs rather than as a
component of the Company's provision for income tax.
 
  Earnings Per Share
 
    Earnings per share is computed by dividing net income by the sum of the
weighted average number of common and common equivalent shares outstanding. The
Company's common equivalent shares, consisting entirely of options to purchase
common stock, are calculated using the treasury stock method which assumes the
exercise of all outstanding stock options with the hypothetical proceeds being
used to repurchase shares for treasury.
 
    Pro forma earnings per share, giving effect to the use of proceeds from the
public offering to repay outstanding debt and the issuance of shares pursuant to
the offering, would have been $0.31 per share for the three months ended March
31, 1995 and $1.10 for the year ended December 31, 1994. 
 
  Concentrations of Credit Risk
 
    The Company's financial instruments that are exposed to concentrations of
credit risk consist primarily of cash equivalents and accounts receivable.
 
    The Company's cash management policy is to use available cash balances,
primarily of its domestic subsidiaries, to reduce the outstanding balance of the
credit facility. To mitigate exposures to foreign currency risks associated with
using the available cash of foreign subsidiaries or joint ventures, only the
portion of available cash balances deemed not to be needed for short-term
operations of the foreign subsidiary are considered eligible for inclusion in
the centralized cash management activities of the Company. The majority of the
cash balance at March 31, 1995 and December 31, 1994, belonged to IABG (as
defined below) (the Company's German subsidiary) (see Note 3). At March 31, 1995
and December 31, 1994, $40,500,000 and $37,040,000, respectively,

  (INFORMATION AS OF AND FOR THE THREE MONTHS ENDED MARCH 31, 1995 AND 1994 IS
                                   UNAUDITED)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES--(CONTINUED)
was invested primarily in deposits with various German banks, with purchased
maturities of one month or less. These investments are insured up to amounts
prescribed by German law. Although there were no other investments as of March
31, 1995, and December 31, 1994, significant excess cash balances of domestic
subsidiaries not used to extinguish debt are routinely invested in high quality
commercial paper for periods ranging from overnight to one week. It is the
Company's policy to hold such investments to maturity.
 
    In connection with its international operations, the Company is exposed to
risks associated with fluctuations in currency exchange rates, including the 
German Mark, the Saudi Riyal, the Kuwaiti Dinar, the Dutch Guilder, and the
Turkish Lira. The Company limits its exposure to these risks by incurring and 
paying for its expenses in the same currencies as those of its revenue. In 
addition, certain contracts performed overseas have provisions which provide for
reimbursement of losses arising from currency fluctuations. It is the Company's
policy not to enter into derivative financial instruments for speculative 
purposes. There were no derivative financial instruments outstanding as of March
31, 1995 and 1994 or as of December 31, 1994, 1993 and 1992.
 
    The Company generally provides uncollateralized credit to its customers.
Advance payments are secured from a large portion of foreign government
customers pursuant to the appropriations practices of the related governments.
The Company also continually assesses the financial strength of commercial
contractors for whom significant subcontracts are performed.
 
  Fair Value of Financial Instruments
 
    The carrying value of financial 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.
 
  Reclassifications
 
    Certain reclassifications have been made to the prior year financial
statements and disclosures to conform them to the current year presentation.
 
3. ACQUISITIONS
 
  Geoscience Consultants, Ltd.
 
    On February 16, 1994, the Company acquired Geoscience Consultants, Ltd., an
environmental services business, for an acquisition price of approximately
$4,300,000. The acquisition was financed with borrowings from the Company's
credit facility. Goodwill resulting from the transaction, accounted for as a
purchase, approximated $3,200,000 and is being amortized on a straight-line
basis over ten years. A three year covenant not-to-compete for $150,000 was also
issued in connection with the acquisition.
 
  Industrieanlagen-Betriebsgesellschaft mbH
 
    On November 16, 1993, the Company acquired management control, through a 45%
ownership interest, in Industrieanlagen-Betriebsgesellschaft mbH (IABG), located
in Ottobrunn, Germany. The interest was acquired primarily from IVG, a company
formerly owned by the German Government

3. ACQUISITIONS--(CONTINUED)
(IVG was privatized during 1993), pursuant to a privatization plan initiated by
the German Government. IABG performs diversified technical services in the areas
of defense technology, information systems, organizational analysis, structural
analysis and testing and environmental programs on behalf of ministries of the
German Government as well as other governmental and private sector clients.
 
    On the original acquisition date, IVG retained a 15% ownership interest in
IABG and held the remaining 40% ownership interest in trust, for sale to
employees and other investors, subject to the Company's approval. In October
1994, 12% of the trust was sold to Buck Werke GmbH & Co. KG, a German services
company, and an additional 5% was acquired by IVG. The Company plans to complete
the privatization of the remaining 23% trust balance through a sale to IABG's
employees and other investors in 1995.
 
    The Company and IVG had originally entered into a voting rights agreement,
which gave the Company control of IVG's 15% voting authority enabling the
Company to exercise 60% in total voting authority. In connection with the sale
of an additional 5% of IABG to IVG in October 1994, the original voting rights
agreement was revised to provide IVG with direct control of 12% of IABG's total
voting authority while ensuring that the Company would retain the right to vote
IVG's remaining 8% ownership for a total voting authority of 53%. IVG cannot
unilaterally terminate the voting rights agreement. In the event that BDM and
IVG cannot agree on a vote, BDM will be required to acquire the 8% portion of
IABG at a price based on a previously accepted valuation method contained in the
original acquisition agreement. The Company's majority voting authority enables
it to manage the operations of IABG; therefore, the accompanying financial
statements consolidate the financial statements of IABG and present the 55%
ownership as minority interest. As long as BDM maintains its ownership position
in IABG, no owner other than BDM will have voting authority exceeding their
ownership percentage.
 
   
    The total consideration paid for the acquisition included the purchase price
of $1,705,500, a finders fee of $2,060,800 and transaction costs of
approximately $2,119,700. The transaction, accounted for as a purchase,
generated an excess of the purchase price over the book value of net assets
acquired of approximately $10,600,000. Due to the unique technical nature of
certain acquired equipment, additional time subsequent to the acquisition
date was needed for extensive analysis by technical experts to appropriately
ascertain a fair value of this equipment.  This subsequent valuation, completed
in September 1994, resulted in the allocation of the entire excess purchase 
price to certain acquired technical equipment and buildings with fair values 
exceeding their respective acquisition date carrying values. Effective 
January 1, 1994, the allocated excess purchase price is being depreciated 
over the estimated useful lives of the specific underlying assets averaging 
nine years, and ranging from three to thirteen years.
    
 
    In addition to the purchase price consideration, the privatization plan
requires the new owners to guarantee equity infusions in IABG of $22,650,000
during the first two years of ownership. As of December 31, 1994, installment
payments against this requirement had been made by the owners at the acquisition
date and on the first anniversary thereof totaling $6,453,000 and $6,236,000,
respectively, representing 100% and 77% of the equity infusions actually
required as of those dates. The remaining 23% portion of the second infusion,
$1,862,000, was paid in March 1995 by a bank trustee which will administer the
remaining ownership transfer to employees and other investors in 1995. The third
installment commitment of $8,098,000, is due from all of the owners on November
16, 1995. The Company's share of all of the above acquisition costs and equity
guarantees is 45%.

3. ACQUISITIONS--(CONTINUED)
  Vinnell Corporation
 
    On March 13, 1992, the Company acquired the outstanding common stock of
Vinnell Corporation (Vinnell) for approximately $29,600,000, including
transaction expenses. The purchase price was $41,700,000, less $16,700,000 of
Vinnell's cash on hand at the acquisition date, a promissory note for $3,700,000
issued to the seller in consideration for a four year not-to-compete agreement
and approximately $900,000 in transaction expenses. The Company also entered
into a consulting agreement with the former owner which provides for annual
compensation of $200,000 per year through 1996. This acquisition, accounted for
as a purchase, generated goodwill of $8,168,000, which is being amortized over
fifteen years.
 
  Pro Forma Information (unaudited)
 
    The following pro forma combined condensed statements of operations set
forth the consolidated results of operations of the Company and these above
mentioned acquisitions as if the transactions had occurred as of January 1, 1994
and 1993 unless actually acquired prior to those dates. This unaudited pro forma
information does not purport to be indicative of the actual financial position
or the results that would actually have occurred if the combinations had been in
effect for the full years ended December 31 (dollars in thousands, except per
share data).

</TABLE>
 
    As of March 31, 1995, December 31, 1994 and 1993, approximately $8,138,000,
$12,146,000 and $18,136,000, respectively, in advance payments from customers
had been applied against the unbilled portion of applicable contract
receivables.
 
    Unbilled retention balances are billable at contract completion or upon
attainment of other specified contract milestones. Other unbilled amounts
consisted primarily of: contractually earned services not yet billable because
of stipulated installment billing provisions, approximately $8,800,000,
$8,400,000 and $1,200,000 at March 31, 1995, December 31, 1994 and 1993,
respectively; revenue recognized pursuant to customer authorizations prior to
the execution of contractual documentation, approximately $1,400,000 ,
$2,430,000 and $11,413,000 at March 31, 1995, December 31, 1994 and 1993,
respectively; and a specific receivable related to a contract whereby the
Company will owe severance to terminated employees at contract completion,
approximately $7,800,000 , $7,770,000 and $7,609,000 at March 31, 1995, December
31, 1994 and 1993, respectively. This liability is included in accrued
severance. Management anticipates that substantially all unbilled receivables as
of March 31, 1995 and December 31, 1994, exclusive of retention balances, will
be billed and collected within one year. Based on the Company's experience with
similar contracts in recent years, retention balances of approximately
$5,000,000, and $6,655,000 at March 31, 1995 and December 31, 1994,
respectively, were are not expected to be collected within the coming year. It
is common industry practice however, to include such amounts in working capital.

    Goodwill recorded in connection with the IABG acquisition in 1993 of
$10,900,000 was reallocated to the excess of the fair values over the
acquisition date carrying values of certain acquired technical equipment and
test facilities as a result of a valuation of all acquired assets and
liabilities, completed in September 1994.
 
    Unamortized goodwill totaling $1,640,000 was expensed during the three
months ended March 31, 1995, as it was determined to be no longer recoverable.
Several factors contributed to this change in recoverability. Transfer of
technology from one industry to another within the acquired company was not 
realized and synergies between BDM technologies and acquired technologies did
not result in an expansion of the customer base as expected. In addition, an 
economic downturn in the Netherlands contributed to a deterioration in the
revenue base. These factors resulted in negative cash flows projected for this
particular business.

    In addition, unamortized goodwill from a separate acquisition totaling
$440,000 was expensed during 1994, as it was determined to be no longer
recoverable. The change in recoverability was driven primarily by the loss of a
significant contract performed by the acquired company, which resulted in
negative cash flows projected for this particular business.

  Restructuring/Severance Liability/Debt Forgiveness
 
    Prior to the Company's acquisition of IABG (See Note 3), IABG found it
necessary to reduce its reliance on the German Government for the majority of
its revenue. In addition to redirecting marketing efforts in non-defense areas,
IABG sought means to reduce operating costs. IABG therefore determined that it
would be necessary to reduce its workforce through involuntary terminations. As
prescribed by German law and pursuant to the German Government plan for
privatization of IABG, a severance plan was developed by IABG providing for the
estimated number of involuntary employee reductions, the conditions for
termination and the method for determining the amount of severance due to the
terminating employees. IABG's workforce reductions began in 1994 and will
continue through 1997. In connection with the approval of the plan by the German
Government and prior to acquisition of IABG by the Company, an estimate for the
severance totalling $35,000,000 was accrued. Benefits paid through December 31,
1994, and during the three months ended March 31, 1995, totalling $7,900,000 and
$2,600,000, respectively, have been applied against the original accrual.
Management believes the remaining liability will be adequate to cover future
benefits claimed pursuant to the plan. The remaining liability as of March 31,
1995, has been classified among current and long-term liabilities according to
IABG's plan for effecting the actual employee reductions.
 
    As an incentive to new investors acquiring IABG, the German Government
privatization plan agreed to fund a portion of the above severance liability in
an amount equal to the principal balance of two notes held by IABG payable to
the German Ministry of Defense (MOD), for a total amount of $10,000,000. As
payments for the severance liability are made to terminated employees, the MOD
is forgiving an equivalent amount of the debt. Severance payments made through
December 31,

    Working Capital Facility. In July 1993, the Company entered into a new
credit agreement which provided for a working capital facility of up to
$100,000,000 for an original term of three years with two options to extend the
term for one additional year. The facility was amended in May 1994, increasing
the borrowing capacity to $125,000,000 and extending the term of the facility
for one of the option years. In April 1995, the Company exercised the second one
year option to extend the term of the facility through July 20, 1998. Through
December 31, 1995, the Company can borrow up to the total amount of the
facility. Effective January 1, 1996, the aggregate amount of borrowing, defined
to include outstanding letters of credit, pursuant to the amendment is limited
to a percentage of the Company's eligible receivables as defined in the
agreement. The Company has the option to borrow principal at interest rates
based either on the bank's prime rate or the LIBOR rate plus margins, with
unused credit also accruing a standard interest charge. The outstanding
borrowings are collateralized by a security interest in the Company's accounts
receivable. Costs incurred to obtain the facility have been capitalized and are
being amortized over the term of the agreement. The Company was eligible to
borrow an additional $58,605,650 and $39,606,163 as of March 31, 1995 and
December 31, 1994, respectively.
 
    The credit agreement contains financial covenants, the most restrictive
being a minimum tangible net worth. Other covenants include minimum fixed charge
coverage and interest coverage ratios and minimum ratios of receivables to
outstanding debt. The agreement contains certain other restrictive covenants
including limitations on new investments and dividends. As of March 31, 1995 and
December 31, 1994, the Company was in compliance with all covenants.
 
    Predecessor Credit Facility. In connection with the early termination of the
predecessor credit facility, the Company recorded an extraordinary loss, net of
the related tax benefit, of $1,300,000 during the year ended December 31, 1993
in connection with the expensing of unamortized debt issuance costs incurred in
obtaining the predecessor facility.

9. DEBT--(CONTINUED)
    The Company had also entered into an interest rate swap agreement to reduce
exposure to changes in interest rates. This agreement, which matured on October
23, 1993, required the payment of interest on a $30,000,000 notional amount at
the spread between the prevailing LIBOR interest rate and 8.01%.
 
    Subordinated Seller Note. In connection with the acquisition of Vinnell in
1992, the Company issued a subordinated promissory note to the former owner in
the amount of $3,700,000. The note bears interest at 10% per annum, and is
payable semi-annually. The principal balance and unpaid accrued interest is due
the earlier of: (1) the fourth anniversary of the acquisition date on March 13,
1996, or (2) six months after the death of the former owner.
 
    FACE Acquisition Note. Effective January 1, 1993, the Company acquired FACE
Holding BV (a Netherlands company). To finance the acquisition, the Company
executed a line of credit arrangement in April 1993 with a Netherlands bank for
up to $2,700,000. The outstanding balance incurred interest at 2% above the
prime rate of the Dutch Central Bank. In August 1994, this amount was repaid
with borrowings from the Company's working capital credit facility.
 
    Subordinated Conditional Note. In connection with the acquisition of the
Company in 1990, in exchange for $3,000,000 in consideration, the Company issued
the right to additional future consideration based upon the Company's actual
earnings before interest and taxes (EBIT) for the years 1991 through 1993. The
Company reflected the $3,000,000 consideration as an estimate for this
liability, thereafter termed the Subordinated Conditional Note. At the
conclusion of 1993, it became evident that the EBIT level necessary to trigger
the additional purchase price consideration would not be attained for any of the
years 1991 through 1993. The Subordinated Conditional Note included a provision
that if the EBIT levels were not met, the Company would not be liable for any
conditional amount, or interest thereon, including the amount paid as
consideration. Accordingly, during the year ended December 31, 1993, the Company
recognized an extraordinary gain of $1,700,000, net of related income tax
expense, on the reversal of the amount initially assigned to the conditional
principal liability. Interest expense had not been accrued on the assigned value
of the right to the conditional principal amount.
 
    Maturities. Maturities of long-term debt outstanding at December 31, 1994,
prior to any exercise of currently available extension options, are as follows:
1996--$3,728,805; 1997-- $79,021,604.
 
    Interest Expense. Total interest expense incurred during the three months
ended March 31, 1995 and 1994 was $1,710,000 and $801,000, reflecting weighted
average interest rates of 8.5% and 5.5%, respectively. Total interest expense
incurred during calendar years 1994, 1993 and 1992 was $5,053,000, $4,631,000
and $5,678,000, respectively. The weighted average interest rate incurred for
the years ended December 31, 1994, 1993 and 1992, respectively was 7.0%, 10.3%
and 10.7%.

10. INCOME TAXES
 
    The provisions for income taxes for the quarters ended March 31, 1995 and
1994 were calculated by applying the projected annual effective rate to income
before tax adjusted for known differences between income before tax for
financial reporting and income tax reporting purposes. The effective rate for
the first quarter of 1995 increased to approximately 52% of pretax income due to
the expensing of $1.6 million in goodwill which is not deductible for income tax
purposes.
 
    The components of income before taxes were as follows for the years ended
December 31, (dollars in thousands):

    As of December 31, 1994, the Company had foreign tax credit carryforwards
(FTC's) of $4,215,000 expiring in various years through 1999. Utilization of the
FTC's is subject to certain limitations, including the future amount of taxable
foreign source income, the effective tax rate on such income and the amount of
future U.S. taxable income. The Company also has a net operating loss
carryforward of $10,700,000 generated by IABG prior to its acquisition in 1993
by the Company to offset future taxable income in Germany. The related deferred
tax asset was entirely reserved as of December 31, 1993 pending the Company's
finalization of purchase accounting for the IABG acquisition. The reserve was
subsequently eliminated in 1994, as a result of this finalization (See Note 3),
since the differences in the basis of depreciable assets for financial reporting
purposes and income tax reporting purposes resulting from IABG's fixed asset
write-up provide assurance of future taxable income for financial reporting
purposes sufficient to utilize the remaining net operating loss carryforward.
The term of this net operating loss carryforward is not limited.
 
    Effective January 1, 1992, the Company adopted SFAS No. 109, which requires
the use of the liability method of accounting for income taxes. The Company
recorded a cumulative charge to income of $115,000 or $.01 per share as a result
of accounting for the difference between the financial reporting and the tax
bases of assets and liabilities. In addition, SFAS 109 required that the Company
restate certain assets and liabilities acquired in prior business combinations
as well as related deferred taxes resulting in a decrease of the remaining
assets of these combinations of $824,000. The effect on 1992 pretax income from
continuing operations as a result of these asset adjustments was a decrease in
income of approximately $360,000.

11. STOCKHOLDERS' EQUITY
 
  Description of Capital Stock
 
    Pursuant to a Certificate of Incorporation revised on March 7, 1994, the
Company is authorized to issue a total of 52,500,000 shares of capital stock,
consisting of 500,000 shares of Preferred Stock, 50,000,000 shares of Common
Stock and 2,000,000 shares of Class B Common Stock, all shares with $.01 par
value. The Preferred Stock may be issuable in one or more series from time to
time at the discretion of the Board of Directors. The Board of Directors is
authorized to fix the respective designation, relative rights, preferences,
qualifications, restrictions, and limitations of each series.
 
    Each share of Common Stock is entitled to one vote in elections of directors
and all other matters required or permitted to be submitted to a vote of the
stockholders. The holders of Class B Common Stock have no voting rights. Holders
of both Common Stock and Class B Common Stock are entitled to receive dividends,
when and if declared by the Board of Directors of the Company. The shares of
Class B Common Stock are convertible into the same number of shares of Common
Stock upon their dispostion in connection with the occurrence of certain events
including a sale of all or substantially all of the Common Stock of the Company;
a merger or consolidation of the Company in which the stockholders of the
Company receive cash and/or marketable securities in exchange for their stock;
and an underwritten public offering of Common Stock of the Company.
 
  Fair Value of Common Stock
 
    Since the acquisition of the Company in October 1990, and through the date
of this report, there has been no public market for the Company's Common Stock
and Class B Common Stock. The fair value of the Company's Common Stock and Class
B Common Stock is determined by the Board of Directors based primarily on
periodic valuations performed by an independent valuation company.
 
  Stockholders Agreement
 
    At the time of the purchase of the Company in October 1990, certain members
of the Company's then senior management (the Management Group), the Carlyle
Group (Carlyle) and certain outside investors (the Investor Group) entered into
a Stockholders Agreement. As subsequently amended, the Stockholders Agreement
provides that the parties subject thereto will vote their shares as follows:
seven directors, designated by Carlyle, five directors designated by the
Management Group, and three independent directors designated jointly by Carlyle
and the Management Group. All recipients of management incentive stock pursuant
to the Management Incentive Stock Purchase Program (see Note 12) are subject to
the terms of the Stockholders Agreement. Upon consummation of a contemplated
public offering, the Stockholders Agreement will terminate in accordance with
the terms.
 
  Investor Stock Purchase Agreement
 
    An Investor Stock Purchase Agreement, also executed at the time of the
purchase of the Company in October 1990, provides the Company and members of the
Investor Group with the right of first refusal in the event any member of the
Investor Group desires to sell the shares purchased under the agreement, subject
to certain exceptions. The agreement also provides for anti-dilution, piggy-back
and demand registration rights. Most of the expenses incurred in connection with
the exercise of such registration rights by certain stockholders would be borne
by the Company.

11. STOCKHOLDERS' EQUITY--(CONTINUED)
  Common Stock Purchase
 
    On May 27, 1994, the Company acquired 2,250,000 shares and 350,000 shares of
its outstanding Common Stock and Class B Common Stock, respectively, from the
Investor Group for its then fair value of $14.00 per share. Subsequent to all
stock purchases to date (See Note 12), the Investor Group still retains a
majority ownership of the Company's outstanding common stock. Coincident with
this stock purchase, these common shares, as well as all previously acquired
treasury shares, were cancelled.
 
12. EQUITY PARTICIPATION PROGRAMS
 
  Employee Stock Purchase Plan
 
    The Company implemented an Employee Stock Purchase Plan in March 1993. The
Plan allows participants to buy Common Stock at the fair market value through
payroll deductions. Each participating employee may purchase up to 26 shares of
Common Stock per month at the fair market value per share. On various occasions
since inception of the Plan, the Company has acquired 74,072, 14,349, 100,000
and 100,000 shares of its outstanding Common Stock at its then fair market value
averaging $13.95, $13.50, $12.00 and $8.00, respectively. During the three
months ended March 31, 1995 and the years ended December 31, 1994 and 1993, the
Plan participants purchased 26,399, 127,120 and 78,229 shares for an average of
$14.93, $12.75 and $8.00 per share, respectively. As of March 31, 1995, the
Company had 50,324 shares reserved for issuance pursuant to the Plan. The
Company's working capital credit facility (see Note 9) limits the number of
outstanding shares that can be acquired each year for the Employee Stock
Purchase Plan to 150,000 shares. The Company reserves the right to discontinue
this plan.
 
  1990 Stock Option Plan
 
    In 1990, the Company established the 1990 Stock Option Plan (the 1990 Plan)
(Non-MIS Plan) to provide officers and key employees with up to 1,562,500
qualified or non-qualified incentive stock options to purchase shares of Common
Stock. The 1990 Plan provides that qualified incentive stock options (as defined
in the Internal Revenue Code) have an exercise price equal to the fair market
value of the Common Stock on the date of the option grant. Non-qualified
incentive stock options have exercise prices as determined by the Compensation
Committee of the Board of Directors. The 1990 Plan provides for adjustments in
the number of shares related to stock options and their respective exercise
prices in the event of stock dividends or stock splits, and for adjustments in
the event that the Company effects a recapitalization or other change in its
capital structure. Options granted pursuant to the 1990 Plan vest over periods
ranging from one to four years. As of March 31, 1995, all options available
pursuant to this Plan had been granted. The Company had 1,311,324 shares of
Common Stock reserved for issuance upon exercise of this Plan's remaining
outstanding options.
 
  1994 Stock Option Plan
 
    In 1994, the Company's Board of Directors reserved 1,000,000 shares of
Common Stock and established the 1994 Stock Option Plan (the 1994 Plan) (Non-MIS
Plan) to succeed the 1990 Plan. The continuation 1994 Plan has identical
provisions as the predecessor 1990 Plan. No options were issued pursuant to this
plan in 1994. At March 31, 1995, the Company had 1,000,000 shares

of Common Stock reserved for issuance upon exercise of outstanding options and
of future option grants.
 
  Management Incentive Stock Purchase Program
 
    In 1991, the Company established the Management Incentive Stock Purchase
Program (MIS Plan), which provides for the granting of up to 1,111,111
nonqualified options to purchase shares of Common Stock to certain senior
members of management. The option exercise price is $.01 per share. Intended to
serve as incentive compensation for the management member, a portion of each
option grant vested each year based on management's ability to meet defined
minimum performance criteria. The majority of remaining outstanding options
became fully vested on March 31, 1995 as the related minimum performance
criteria established for 1994 was achieved. Upon option grant, the Company
records deferred compensation equal to the difference between the fair market
value of the Company's Common Stock on the date of grant and the option exercise
price. The deferred compensation is expensed over the vesting term of the
underlying options. As of March 31, 1995, the Company had 98,921 shares of
Common stock reserved for issuance upon exercise of the outstanding options and
for issuance upon exercise of future option grants.
 
    Stock option activity pursuant to these plans has been as follows:

  Directors' Stock Purchase Plan
 
    Members of the Company's Board of Directors are eligible to receive their
compensation in the form of Common Stock in lieu of cash. During the first
quarter of 1995 and during 1994 and 1993, the Company issued 3,752, 14,296 and
23,018 shares, respectively, of Common Stock for this purpose. During 1994, the

share for use by this plan. As of March 31, 1995, the Company had 13,935 shares
of Common Stock reserved for issuance upon the exercise of the board members'
option to receive compensation in this form.
 
13. RETIREMENT PLANS
 
    The Company maintains a 401(k) plan covering substantially all full-time
employees of the Company's domestic subsidiaries. Employees may direct the
investment of their contributions among several mutual fund options. Employees
may contribute up to the maximum allowed by federal regulations, currently 15%
of their monthly salary or a maximum of $9,240. The Company contributes an
amount equal to 25% of the first 4% of the employee's salary contributed to the
plan by the employee. For the three months ended March 31, 1995 and 1994, and
for the years ended December 31, 1994, 1993 and 1992, the Company's contribution
was approximately $189,000, $203,000, $842,430, $719,000 and $657,000,
respectively. At the time of the Company's change in ownership in 1990,
employees were allowed a one-time option to purchase the Company's Common Stock
with balances in their plan. A total of 342,979 common shares were held by the
participants of the plan as of December 31, 1994 and March 31, 1994.
 
    The Company also sponsors several other defined contribution plans for
substantially all of the employees of IABG. Participation in the plans is
voluntary; however, participants are required to make contributions to the plans
equal to 50% of the amount of the Company contribution. Company contributions
are based on percentages of the employees' monthly salary up to maximum monthly
benefits. The plans are fully funded and assets of the plans are invested in
insurance company annuities. The Company incurred $955,000, $800,000, $3,453,000
and $423,000, respectively, in plan contribution expense for the three months
ended March 31, 1995 and 1994 and for the year ended December 31, 1994 and in
1993 since the November 16, 1993 acquisition date.
 
    The Company has a defined benefit pension plan (the Retirement Plan) and a
supplemental executive retirement plan (SERP) providing noncontributory
retirement benefits for eligible employees. Benefits are determined based upon
years of service and employee compensation. The Company's funding policy is to
contribute annually, at a minimum, amounts required by applicable laws and
regulations. Retirement Plan assets are invested principally in a group annuity
contract with an insurance company, as well as in a portfolio of diversified
equity securities and mutual funds.

13. RETIREMENT PLANS--(CONTINUED)
$6,444,000, and $5,699,000 for this pension obligation as of March 31, 1995 and
December 31, 1994, respectively. The contribution expense amounted to $33,000
and $70,000 for the three months ended March 31, 1995 and 1994 and to $554,000
in calendar year 1994 and to $128,000 for the period of ownership in 1993. No
additional pension disclosures required by SFAS 87 have been provided since the
majority of the members covered by the plan have retired and the liability
reflected in these financial statements for this plan will not increase
significantly in the future.
 
    The Company maintains a self-insurance plan to cover the costs of certain
employee health benefits. As of March 31, 1995, December 31, 1994 and 1993, the
estimated balance accrued for the cost of incurred but unreported claims was
approximately $2,000,000. The Company's annual liability for claims expense is
contractually limited pursuant to an agreement with an insurance company. The
actual claims expense for 1994 did not exceed the contractual maximum.
 
14. TRANSACTIONS WITH RELATED PARTIES
 
    The Chairman, Vice Chairman and a member of the Company's Board of Directors
are the Chairman and two Managing Directors, respectively, of Carlyle. The
Company retains Carlyle to provide certain advisory and consulting services for
an annual fee of $500,000 plus expenses. Total amounts incurred by the Company
related to these services for the three months ended March 31, 1995 and 1994 and
for the years ended December 31, 1994, 1993 and 1992 were approximately
$125,000, $125,000, $505,000, $535,000 and $512,000, respectively. Upon
completion of a contemplated public offering, Carlyle will waive its right to
receive this fee in the future in exchange primarily for a number of shares of
Common Stock to be determined by dividing $1,620,000 by the initial public
offering price per share of the shares of Common Stock offered thereby. Also in
1992, the Company paid $250,000 to Carlyle as an advisory fee for services
rendered in connection with the acquisition of Vinnell.
 
    Prior to its privatization by the German Government in 1993, IVG was
majority owned by the German Government (See Note 3). Contract revenue derived
by IABG from the German Government and its ministries totalled $28,950,000 and
$21,736,000 for the three months ended March 31, 1995 and 1994, and $118,543,000
for the year ended December 31, 1994, and $16,300,000 for the period from
November 17, 1993 through December 31, 1993. The total amount receivable from
the German Government at March 31, 1995 and December 31, 1994 and 1993 was $0,
$3,325,476 and $11,576,000, respectively.
 
    IABG leases most of its facilities from IVG (a 20% owner of IABG). Total
rent expense incurred with IVG for the three months ended March 31, 1995 and
1994 was $1,926,000 and $1,840,000, respectively, and was $7,305,000 and
$1,054,000 for the year ended December 31, 1994 and for the period in 1993 since
the acquisition by the Company. IABG earns a market rate of interest on a
related $5,000,000 lease deposit with IVG. Interest income earned during 1994
since the installment payments of the lease deposit in 1994 totalled $19,700.

17. COMMITMENTS AND CONTINGENCIES
 
  Government Audits
 
    Payments to the Company on United States or foreign government contracts are
subject to adjustments upon audit by various agencies of the respective
governments. Audits currently in progress are in varying stages of completion;
however, management does not expect the results of these audits, or audits
related to any operations prior to March 31, 1995 and December 31, 1994,
subsequently initiated, to have a material effect on the Company's financial
position or results of future operations.
 
  Litigation and Claims
 
    The Company is a party to various legal actions, claims, government
inquiries and audits resulting from the normal course of business. Although the
total amount of liability with respect to these matters cannot be ascertained,
management of the Company believes that any resulting liability should not have
a material adverse effect on the Company's financial position or results of
operations.

17. COMMITMENTS AND CONTINGENCIES--(CONTINUED)
  Environmental Matters
 
    One of the Company's wholly owned subsidiaries was previously notified by
the United States Environmental Protection Agency (EPA) that it is one of
several potentially responsible parties (PRPs) for remediation in connection
with asbestos present at two sites. The subsidiary, along with another PRP,
entered into a consent decree with the EPA in 1992, by which the subsidiary and
the other PRP are obligated to reimburse the EPA for costs incurred in its
assessment and monitoring of approximately $1,600,000 and to undertake work to
address the environmental exposure as defined in the consent decree. The Company
originally accrued $4,400,000 which management believed to be the best estimate
of the liability for this claim. Amounts paid and charged against this provision
through 1994 total approximately $2,019,000. Management believes that the
remaining accrual for this contingency of $2,381,000 is sufficient to cover
costs to be incurred related to the subsidiary's performance pursuant to the
consent decree.
 
   
    Another of the Company's subsidiaries was previously notified by the
Massachusetts Department of Environmental Protection that it is also one of
several PRPs in an environmental matter arising as a result of work performed on
a contract with the U.S. Air Force.  The U.S. Air Force reimbursed the Company
for all costs incurred to date in connection with this matter.  No costs were
incurred by the Company in 1995 or 1994 relative to this contingency.  No
accrual has been recorded as of March 31, 1995 as the risk of loss to the
Company is considered to be remote, and the remaining potential amounts
involved are considered to be immaterial.
    
 
  Lease Obligations
 
    The Company leases office space and equipment under various operating lease
agreements. Leases for principal office space typically have terms of five to
twenty years and carry optional renewal periods of five to twenty years. Most
leases include provisions for periodic rent escalations based on changes in
various economic indices. Amounts representing aggregate rent expense on all
operating leases, excluding equipment rented for use on specific contracts and
reimbursed pursuant to the terms of those contracts, totalled $7,686,000,
$8,014,000, $35,426,000, $23,933,000 and $22,756,000 for the three months ended
March 31, 1995 and 1994 and for the years ended December 31, 1994, 1993 and
1992, respectively.
 
    Future minimum payments on non-cancellable operating leases were as follows
on December 31, 1994 (dollars in thousands):

17. COMMITMENTS AND CONTINGENCIES--(CONTINUED)
    The Company's share of the future minimum lease commitments of IABG is 45%.
The remaining 55% commitment is the responsibility of the subsidiary's other
owners.
 
    IABG is required to provide cash collateral of $6,400,000 to the lessor for
its facilities which are leased through the year 2004. Approximately $4,800,000
of this commitment was paid in 1994 and the remaining $1,600,000 is due on
November 16, 1995. The amount of the collateral balance will be reduced by the
landlord by $2,400,000 prior to the end of the lease term in $600,000 increments
paid every two years beginning on November 16, 1997. Cash on deposit is
interest-bearing and interest income will accrue at current market rates payable
quarterly.
 
    After the termination of certain of the leases for operating facilities of
IABG, the Company is liable for costs to be incurred, cumulatively up to
$7,000,000 adjusted for inflationary changes in a specified economic index, for
any removal or repair of buildings and facilities deemed necessary by the
lessor. For any year that the related lease is extended beyond the year 2013,
the commitment is reduced by 1/10th per year to a minimum commitment of
$1,000,000. The Company's share of the reclamation costs would be 45%. No
amounts have been accrued for this contingency.
 
  Sublease Commitments
 
    Sublease rental income earned was $990,000, $1,106,000, $4,379,000,
$2,579,000 and $1,312,000 during the three months ended March 31, 1995 and 1994
and during the years ended December 31, 1994, 1993 and 1992, respectively.
Future minimum payments on non-cancellable subleases were as follows as of
December 31, 1994 (dollars in thousands):

                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Upon the completion of the Offerings, the Company will have 11,975,656
shares of Common Stock and Class B Common Stock outstanding. Of these shares,
the 2,500,000 shares of Common Stock sold in the Offerings, the 1,339,217 shares
of Common Stock sold in the 1991 Offering and the 1,562,500 shares of Common
Stock issued, or to be issued, upon exercise of stock options granted under the
1990 Option Plan that have been registered under the Securities Act pursuant to
registration statements on Form S-8 will be freely tradable without restriction
under the Securities Act by persons other than "affiliates" of the Company
without restriction under the Securities Act. In addition, the Company currently
intends to register the shares of Common Stock under the 1994 Stock Option Plan
pursuant to which options to purchase 186,432 shares have been granted. If
registered, such shares will be freely tradable as described above. An
additional 360,000 shares of Common Stock are reserved for issuance under the
Company's Employee Stock Purchase Plan (the "Employee Stock Purchase Plan") of
which 231,748 shares had been issued as of March 31, 1995, and will be freely
tradable without restriction under the Securities Act when issued. The remaining
7,653,515 shares of issued and outstanding Common Stock were acquired in
transactions that were exempt from registration under the Securities Act and
consequently may not be resold unless they are registered under the Securities
Act or are sold pursuant to an applicable exemption from registration, including
Rule 144 under the Securities Act.
 
    In general, under Rule 144 as presently in effect, if a period of at least
two years has elapsed since the later of the date the "restricted shares" (as
that phrase is defined in Rule 144) were acquired from the Company and the date
they were acquired from an "affiliate" (as that term is defined in Rule 144) of
the Company, as applicable, then the holder of such restricted shares (including
an affiliate) is entitled to sell a number of shares within any three-month
period that does not exceed the greater of 1% of the then outstanding shares of
the Common Stock (approximately 120,000 shares immediately after the
consummation of the Offerings, assuming the over-allotment options are not
exercised) or the average weekly trading volume reported by the Nasdaq National
Market in the Common Stock during the four calendar weeks preceding such sale.
The holder may only sell such shares through unsolicited brokers' transactions.
Sales under Rule 144 are also subject to certain requirements pertaining to the
manner of such sales, notices of such sales and the availability of current
public information concerning the Company. Affiliates may sell shares not
constituting restricted securities in accordance with the foregoing volume
limitations and other requirements but without regard to the two-year period.
 
    Under Rule 144(k), if a period of at least three years has elapsed since the
later of the date restricted shares were acquired from the Company and the date
they were acquired from an affiliate of the Company, as applicable, then a
holder of such restricted shares who is not an affiliate of the Company at the
time of the sale and who has not been an affiliate of the Company for at least
three months prior to the sale would be entitled to sell the shares immediately
without regard to the volume limitations and other conditions described above.
 
    The Company has filed two registration statements on Form S-8 under the
Securities Act to register the shares of Common Stock reserved for issuance
under the 1990 Stock Option Plan and the Employee Stock Purchase Plan. The
Company intends to file an additional registration statement on Form S-8 under
the Securities Act to register the shares of Common Stock reserved for issuance
under the 1994 Stock Option Plan. Shares registered pursuant to such
registration statements are freely tradable except to the extent that the
holders thereof are deemed to be "affiliates" of the Company, in which case the
transferability of such shares will be subject to the volume limitations set
forth in Rule 144 under the Securities Act.
 
    The Company, the Principal Stockholders and certain directors and executive
officers have agreed that during the period beginning on the date of this
Prospectus and continuing to and including the date 180 days after the date of
this Prospectus, not to offer, sell, contract to sell or otherwise dispose of
any shares of Common Stock or any securities of the Company which are
 
                                       53
<PAGE>
substantially similar to the Common Stock, including securities which are
convertible into or exchangeable for, or represent the right to receive, Common
Stock or any such substantially similar securities (other than pursuant to
employee stock option plans, employee stock purchase plans or 401(k) plans
existing on the date of this Prospectus or in an acquisition in which the person
or persons receiving the Common Stock or substantially similar securities agree
in writing to be bound by this clause) without the prior written consent of the
representatives of the Underwriters except for the shares of Common Stock
offered in connection with the concurrent U.S. and international offerings..
 
    As of March 31, 1995, the Company had reserved 1,579,735 shares of Common
Stock for issuance upon exercise of outstanding stock options and 830,510 shares
of Common Stock for issuance upon exercise of future option grants.
 
    Prior to the Offerings, there has been no public market for the Common
Stock. The Company can make no predictions as to the effect, if any, that sales
of shares of Common Stock or the availability of shares of Common Stock for sale
will have on the market price prevailing from time to time. Nevertheless, sales
of substantial amounts of the Common Stock in the public market, or the
perception that such sales may occur, could adversely affect prevailing market
prices.
 
REGISTRATION RIGHTS
 
    Pursuant to the Investor Agreement, upon completion of the Offerings, the
stockholders who are subject thereto have registration rights with respect to
6,700,000 shares of Common Stock. Such stockholders have the right, subject to
certain exceptions in the case of an underwritten public offering, to include
their shares in any registration statement relating to Common Stock (or other
securities) filed by the Company under the Securities Act. Once the Common Stock
is traded on the Nasdaq National Market, Investor Group members and transferees
of their shares of Common Stock (pursuant to transactions that are not Exempt
Transactions) holding, at the relevant time, an aggregate of more than 25% of
the total number of shares of Common Stock held by the parties to such agreement
and their transferees, also have the right to require the Company, subject to
certain limitations, to file four registration statements under the Securities
Act in respect of more than 25% of the Common Stock owned in the aggregate by
the parties to such agreement. All of such stockholders have waived all of their
registration rights with respect to this Offerings and to any other registration
statements filed by the Company within 180 days after the date of this
Prospectus. In connection with these piggy-back and demand registration rights,
the Company will pay certain of such stockholders' registration expenses, but
not discount or commission expenses in connection with sales of the shares owned
by such stockholders.

                     CERTAIN UNITED STATES TAX CONSEQUENCES
                      TO NON-U.S. HOLDERS OF COMMON STOCK
 
    The following is a general discussion of certain U.S. federal income and
estate tax consequences of the ownership and disposition of Common Stock by a
person that, for U.S. federal income tax purposes, is a non-resident alien
individual, a foreign corporation, a foreign partnership or a foreign estate or
trust (a "non-U.S. holder"). This discussion does not consider specific facts
and circumstances that may be relevant to a particular holder's tax position
(including the tax position of certain U.S. expatriates) and does not deal with
U.S. state and local or non-U.S. tax consequences. Furthermore, the following
discussion is based on provisions of the U.S. Internal Revenue Code of 1986, as
amended (the "Code"), and administrative and judicial interpretations as of the
date hereof, all of which are subject to change. Each prospective holder is
urged to consult a tax advisor with respect to the U.S. federal tax consequences
of acquiring, holding and disposing of Common Stock as well as any tax
consequences that may arise under the laws of any U.S. state, municipality or
other tax jurisdiction.
 

DIVIDENDS
 
    Dividends paid to a non-U.S. holder of Common Stock will be subject to
withholding of U.S. federal income tax at a 30% rate or such lower rate as may
be specified by an applicable income tax treaty, unless the dividends are
effectively connected with the conduct of a trade or business within the United
States or, if an income tax treaty applies, are attributable to a U.S. permanent
establishment of such holder. Dividends that are effectively connected with such
holder's conduct of a trade or business in the United States or, if an income
tax treaty applies, are attributable to a U.S. permanent establishment of such
holder, are subject to tax at rates applicable to U.S. citizens, resident aliens
and domestic U.S. corporations, and are not generally subject to withholding.
Any such effectively connected dividends received by a non-U.S. corporation may
also, under certain circumstances, be subject to an additional "branch profits
tax" at a 30% rate or such lower rate as may be specified by an applicable
income tax treaty.
 
    Under current United States Treasury regulations, dividends paid to an
address in a foreign country are presumed to be paid to a resident of that
country (unless the payor has knowledge to the contrary) for purposes of the
withholding discussed above and, under the current interpretation of the United
States Treasury regulations, for purposes of determining the applicability of a
tax treaty rate. Under proposed United States Treasury regulations, not
currently in effect, however, a non-U.S. holder of Common Stock who wishes to
claim the benefit of an applicable treaty rate would be required to satisfy
applicable certification and other requirements.
 
    A non-U.S. holder of Common Stock that is eligible for a reduced rate of
U.S. withholding tax pursuant to a tax treaty may obtain a refund of any excess
amounts currently withheld by filing an appropriate claim for refund with the
U.S. Internal Revenue Service.
 
GAIN ON DISPOSITION OF COMMON STOCK
 
    A non-U.S. holder generally will not be subject to U.S. federal income tax
in respect of gain recognized on a disposition of Common Stock unless (i) the
gain is effectively connected with a trade or business of the non-U.S. holder in
the United States , (ii) in the case of a non-U.S. holder who is an individual
and holds the Common Stock as a capital asset, such holder is present in the
United States for 183 or more days in the taxable year of the sale and either
(a) such individual's "tax home" for the U.S. federal income tax purposes is in
the United States, or (b) the gain is attributable to an office or other fixed
place of business maintained in the United States by such individual, or (iii)
the Company is or has been a "U.S. real property holding corporation" for
federal income tax purposes and the non-U.S. holder held, directly or
indirectly, at any time during the five-year period ending on the date of
disposition, more than 5% of the Common Stock. The Company has not been, is not,
and does not anticipate becoming a "U.S. real property holding corporation" for
federal income tax purposes.

                                    55


<PAGE>
 
FEDERAL ESTATE TAXES
 
    Common Stock held by a non-U.S. holder at the time of death will be included
in such holder's gross estate for U.S. federal estate tax purposes, unless an
applicable estate tax treaty provides otherwise.
 
U.S. INFORMATION REPORTING REQUIREMENT AND BACKUP WITHHOLDING TAX
 
    U.S. information reporting requirements, other than reporting of dividend
payments for purposes of the withholding tax noted above, and backup withholding
tax generally will not apply to dividends paid to non-U.S. holders that are
either subject to the 30% withholding discussed above or that are not so subject
because an applicable tax treaty reduces such withholding. Otherwise, backup
withholding of U.S. federal income tax at a rate of 31% may apply to dividends
paid with respect to the Common Stock to holders that are not "exempt
recipients" and that fail to provide certain information (including the holder's
U.S. taxpayer identification number) in the manner required by U.S. law and
applicable regulations. Generally, the payor of the dividends may rely on
the payees' address outside the United States in determining that the
withholding discussed above applies, and consequently, that the backup
withholding provisions do not apply.
 
    As a general proposition, U.S. information reporting and backup withholding
also will not apply to a payment made outside the United States of the proceeds
of a sale of Common Stock through an office outside the United States of a
non-U.S. broker. However, U.S. information reporting requirements (but not
backup withholding) will apply to a payment made outside the United States of
the proceeds of a sale of Common Stock through an office outside the United
States of a broker that is a U.S. person, that derives 50% or more of its gross
income for certain periods from the conduct of a trade or business in the United
States, or that is a "controlled foreign corporation" as to the United States,
unless the broker has documentary evidence in its records that the holder is a
non-U.S. holder and certain conditions are met or the holder otherwise
establishes an exemption. Payment by a U.S. office of a broker of the proceeds
of a sale of Common Stock is currently subject to both U.S. backup withholding
and information reporting unless the holder certifies non-U.S. status under
penalties of perjury or otherwise establishes an exemption.
 
    A non-U.S. holder generally may obtain a refund of any excess amounts
withheld under the backup withholding rules by filing the appropriate claim for
refund with the U.S. Internal Revenue Service.

</TABLE>
 
    Under the terms and conditions of the Underwriting Agreement, the
International Underwriters are committed to take and pay for all of the shares
offered hereby, if any are taken.
 
    The International Underwriters propose to offer the shares of Common Stock
in part directly to the public at the public offering price set forth on the
cover page of this Prospectus and in part to certain securities dealers at such
price less a concession of $       per share. The International Underwriters may
allow, and such dealers may reallow, a concession not in excess of $       per
share to certain brokers and dealers. After the shares of Common Stock are
released for sale to the public, the offering price and other selling terms may
from time to time be varied by the representatives.
 
    The Company has entered into an underwriting agreement (the "U.S.
Underwriting Agreement") with the underwriters of the U.S. Offering (the "U.S.
Underwriters") providing for the concurrent offer and sale of 2,000,000 shares
of Common Stock in a U.S. offering in the United States. The offering price and
aggregate underwriting discounts and commissions per share for the two offerings
are identical. The closing of the International Offering is a condition to the
closing of the U.S. offering, and vice versa. The representatives of the U.S.
Underwriters are Goldman, Sachs & Co. and Lehman Brothers Inc.
 
    Pursuant to an Agreement between the U.S. and International Underwriting
Syndicates (the "Agreement Between") relating to the two offerings, each of the
U.S. Underwriters has agreed that, as a part of the distribution of the shares
offered hereby and subject to certain exceptions, it will offer, sell or deliver
the shares of Common Stock, directly or indirectly, only in the United States of
America (including the States and the District of Columbia), its territories,
its possessions and other areas subject to its jurisdiction (the "United
States") and to U.S. persons, which term shall mean, for purposes of this
paragraph: (a) any individual who is a resident of the United States or (b) any
corporation, partnership or other entity organized in or under the laws of the
United States or any political subdivision thereof and whose office most
directly involved with the purchase is located in the United States. Each of the
International Underwriters named herein has agreed pursuant to the Agreement
Between that, as a part of the distribution of the shares offered as a part of
the international offering, and subject to certain exceptions, it will (i) not,
directly or indirectly, offer, sell or deliver shares of Common Stock (a) in the
United States or to any U.S. persons or (b) to any person who it believes
intends to reoffer, resell or deliver the shares in the United States or to any
U.S. persons, and (ii) cause any dealer to whom it may sell such shares at any
concession to agree to observe a similar restriction.
 
                                   57
<PAGE>

    Pursuant to the Agreement Between, sales may be made between the U.S.
Underwriters and the International Underwriters of such number of shares of
Common Stock as may be mutually agreed. The price of any shares so sold shall be
the initial public offering price, less an amount not greater than the selling
concession.
 
    The Company has granted the International Underwriters an option exercisable
for 30 days after the date of the Prospectus to purchase up to an aggregate of
75,000 additional shares of Common Stock solely to cover over-allotments, if
any. If the International Underwriters exercise their over-allotment option, the
International Underwriters have severally agreed, subject to certain conditions,
to purchase approximately the same percentage thereof that the number of shares
to be purchased by each of them, as shown in the foregoing table, bears to the
500,000 shares of Common Stock offered hereby. The Company has granted the U.S.
Underwriters a similar option exercisable up to an aggregate of 300,000
additional shares of Common Stock.
 
    The Company, the Principal Stockholders and certain directors and executive
officers have agreed that during the period beginning from the date of this
Prospectus and continuing to and including the date 180 days after the date of
the Prospectus, not to offer, sell, contract to sell or otherwise dispose of any
shares of Common Stock or any securities of the Company which are substantially
similar to the shares of Common Stock, including but not limited to securities
which are convertible into or exchangeable for, or represent the right to
receive, Common Stock or any such substantially similar securities (other than,
with respect to the Company pursuant to employee stock option plans, employee
stock purchase plans, 401(k) plans or any other employee plans of similar
nature, including, without limitation, any such plans for the benefit of
directors or officers of the Company, which are described in this Prospectus or
in an acquisition in which the person or persons receiving the Common Stock or
substantially similar securities agree in writing to be bound by this clause)
without the prior written consent of the representatives, except for the shares
of Common Stock offered in connection with the concurrent U.S. and international
offerings.
 
   
    Each International Underwriter has also agreed that (a) it has not offered
or sold and prior to the date six months after the date of issue of the shares
of Common Stock will not offer or sell any shares of Common Stock to persons
in the United Kingdom except to persons whose ordinary activities involve them
in acquiring, holding, managing or disposing of investments (as principal or
agent) for the purposes of their businesses or otherwise in circumstances
which have not resulted and will not result in an offer to the public in the
United Kingdom within the meaning of the Public Offers of Securities
Regulations 1995, (b) it has complied, and will comply with, all applicable 
provisions of the Financial Services Act of 1986 of Great Britain with respect 
to anything done by it in relation to the shares of Common Stock in, from or 
otherwise involving the United Kingdom, and (c) it has only issued or passed 
on and will only issue or pass on in the United Kingdom any document received 
by it in connection with the issuance of the shares of Common Stock to a 
person who is of a kind described in Article 11(3) of the Financial Services 
Act 1986 (Investment Advertisements) (Exemptions) Order 1995 of Great Britain 
or is a person to whom the document may otherwise lawfully be issued or passed 
on.
    
 
    Buyers of shares of Common Stock offered hereby may be required to pay stamp
taxes and other charges in accordance with the laws and practice of the country
of purchase in addition to the initial public offering price.
 
    The representatives of the Underwriters have informed the Company that they
do not expect sales to accounts over which the Underwriters exercise
discretionary authority to exceed five percent of the total number of shares of
Common Stock offered by them.
 
    Prior to the offerings, there has been no public market for the shares. The
initial public offering price will be negotiated among the Company and the
representatives of the International Underwriters and U.S. Underwriters. Among
the factors to be considered in determining the initial public offering price of
the 
                                    58
<PAGE>

Common Stock, in addition to prevailing market conditions, are the Company's
historical performance, estimates of the business potential and earnings
prospects of the Company, an assessment of the Company's management and the
consideration of the above factors in relation to market valuation of companies
in related businesses.
 
    Application has been made for the Common Stock to be approved for quotation
and trading on the Nasdaq National Market under the symbol BDMI.
 
    The Company has agreed to indemnify the several Underwriters against certain
liabilities, including liabilities under the Securities Act.
 
                            VALIDITY OF COMMON STOCK
 
    The validity of the Common Stock offered hereby will be passed upon for the
Company by Willkie Farr & Gallagher, New York, New York, and for the
International Underwriters by Sullivan & Cromwell, Washington, D.C.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    Section 145 of the DGCL empowers a Delaware corporation to indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of such corporation), by reason of the fact that such person is or was a
director, officer, employee or agent of such corporation, or is or was serving
at the request of such corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise. A
corporation may, in advance of the final disposition of any civil, criminal,
administrative or investigative action, suit or proceeding, pay the expenses
(including attorneys' fees) incurred by any officer, director, employee or agent
in defending such action, provided that such person undertakes to repay such
amount if it shall ultimately be determined that he is not entitled to be
indemnified by the corporation. A corporation may indemnify such person against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by such person in connection with
such action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful.
 
    A Delaware corporation may indemnify officers and directors in an action by
or in the right of the corporation to procure a judgment in its favor under the
same conditions, except that no indemnification is permitted without judicial
approval if the officer or director is adjudged to be liable to the corporation.
Where an officer or director is successful on the merits or otherwise in the
defense of any action referred to above, the corporation must indemnify him
against the expenses (including attorneys' fees) which he actually and
reasonably incurred in connection therewith. The indemnification provided is not
deemed to be exclusive of any other rights to which an officer or director may
be entitled under any corporation's by-laws, agreement, vote or otherwise.

    In accordance with Section 145 of the DGCL, Section 13 of the By-laws
provides that the Company shall indemnify any director, officer or employee of
the Company entitled to indemnity under the DGCL to the fullest extent permitted
by the DGCL; provided, however, that the Company may not be permitted to
indemnify any person in connection with any proceeding initiated by such person,
unless such proceeding is authorized by a majority of the directors of the
Company. Article Eighth of the Certificate of Incorporation provides that a
director of the Company shall not be personally liable to the Company or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except for liability (i) for any breach of the director's duty of loyalty to the
Company or its shareholders, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the DGCL or (iv) for any transaction from which the director
derived an improper personal benefit. If the DGCL is amended to authorize
further elimination or limitation of personal liability of directors, then the
liability of a director of the Company shall be eliminated or limited to the
fullest extent permitted by the DGCL, as so amended. Any repeal or modification
of Article Eighth of the Certificate of Incorporation will not adversely affect
any right or protection of a director of the Company existing at the time of
such repeal or modification.
 
    Section 8 of the Underwriting Agreement, a form of which is included in
Exhibit 1.1 to this Registration Statement, provides for indemnification of
directors and officers of the Company by the Underwriters against certain
liabilities, including certain liabilities under the Securities Act.

    2. In connection with the 1990 Acquisition, the Company sold 100,000 shares
of Series A Preferred Stock to The Carlyle Fund at a purchase price of $100.00
per share.
 
    3. In connection with the 1990 Acquisition, the Company issued to LAC a
Conditional Note, dated October 23, 1990, which expired October 23, 1994.
 
    4. In connection with the 1991 Offering, the Company sold 1,500,000 shares
of Common Stock to The Carlyle Fund at a purchase price of $4.00 per share.
 
    5. In May 1991, the Company sold 500,000 shares of Common Stock to The
Carlyle Fund at a purchase price of $4.00 per share.
 
    6. To finance the acquisition of the outstanding common stock of Vinnell in
March 1992, the Company issued to the seller a subordinated promissory note,
dated March 13, 1992, in the principal amount of $3.7 million at an annual
interest rate of 10%.
 
    7. In connection with the acquisition of FACE, effective January 1, 1993,
the Company issued to ING Bank in April 1993 a note in the principal amount of
approximately $2.75 million which bears interest at the rate of 2% above the
prime rate of the Dutch Central Bank. This note was repaid in full in August
1994.
 
    8. In connection with the execution and delivery of the Credit Facility, the
Company and the subsidiaries of the Company named therein issued a Revolving
Credit Note, dated July 20, 1993, in the principal amount of $100 million and
payable jointly and severally by the Company and the
 
                                      II-2
<PAGE>
subsidiaries of the Company named therein. The Credit Facility was amended to
$125 million on May 27, 1994.
 
    9. Under the 1990 Stock Option Plan, the Compensation Committee of the Board
of Directors granted to certain employees incentive stock options to purchase a
total of 1,562,500 shares of Common Stock, net of forfeitures, at an exercise
price ranging from $4.00 to $17.25 per share, since the inception of the plan on
December 1990.
 
    10. Under the Director Stock Purchase Program, the Company sold to certain
directors a total of 56,113 shares of Common Stock at a purchase price ranging
from $5.25 to $17.25 per share, since the inception of the program on July 1992.
 
    11. Since December 1990, the Compensation Committee has granted to selected

inception of the program on March 1993. A registration statement on Form S-8 was
filed by the Company with respect to 100,000 shares of such Common Stock;
however, no registration statement was filed with respect to the balance of such
shares and there may be no exemption from registration available with respect
thereto. The Company is therefore in the process of registering, and conducting
a rescission offer for, shares pursuant to a registration statement.
 
    13. Under the 1994 Stock Option Plan, the Compensation Committee of the
Board of Directors granted to certain employees incentive stock options to

securities. Except for item (12) above, such sales were made in reliance upon
the exemption from the registration provisions of the Securities Act set forth
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
 
    (1) 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
Underwriter to permit prompt delivery to each purchaser.
 
    (2) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to its Certificate of Incorporation, By-Laws, the
Underwriting Agreement 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 Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
 
                                      II-5

    (3) The Registrant hereby undertakes that:
 
        (a) For purposes of determining any liability under the Securities Act,
    the information omitted from the form of prospectus filed as part of this
    Registration Statement in reliance upon Rule 430A and contained in a form of
    prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
    497(h) under the Securities Act shall be deemed to be part of the
    Registration Statement as of the time it was declared effective.
 
        (b) For the purpose of determining any liability under the Securities
    Act, each post-effective amendment that contains a form of prospectus shall
    be deemed to be a new registration statement relating to the securities
    offered therein, and this offering of such securities at that time shall be
    deemed to be the initial bona fide offering thereof.
