                                  THE COMPANY

    Anteon is a leading provider of advanced information technology and
engineering systems and services. We serve hundreds of governmental clients,
principally within the U.S. Federal government, from 39 offices worldwide. We
have performed work for the U.S. Congress and all 14 Cabinet-level government
agencies, designing, maintaining and upgrading critical systems such as defense,
intelligence, emergency response, logistics support and financial management
systems. For the year ended December 31, 1998, we performed work on
approximately 3,000 task orders on more than 500 contracts. In addition, during
the past four years, we have increased revenues at a 32.0% compound annual
growth rate including a 19.9% compound annual growth rate excluding
acquisitions. Pro forma for our acquisition of A&T described below under "--The
Transactions," our 1998 revenues and Adjusted EBITDA (as defined) were $450.8
million and $35.1 million, respectively. Similarly, cash flows used in
operations on a pro forma basis were $2.3 million for 1998.

    The Federal government is among the world's largest purchasers of
information technology, with total expenditures in fiscal 1999 expected to be in
excess of $30 billion and expected to increase by approximately 4.4% per annum
from $29.5 billion in 1998 to $35.1 billion in 2002. Due to projected increased
Federal government outsourcing, the amount of information technology services
procured from contractors is expected to increase at a faster rate, by
approximately 6.9% per annum from 1998 to 2002. We believe that the emphasis of
the Federal government on downsizing and budget constraints for large new
projects will continue to result in the increased use of technology to enhance
productivity with expenditures focused on upgrading existing equipment and
systems, including many that we designed and are currently supporting. In this
environment, contractors like us that are capable of providing complete
end-to-end technology services across a number of applications are
well-positioned to take advantage of the opportunities presented by these
trends.

    We have developed over a 22-year period the expertise and capabilities to
deliver a broad range of technology solutions. For example, we are currently
working with the U.S. Federal Emergency Management Agency to design and
integrate the National Emergency Management Information System, a management
information system that enables the White House and other governmental offices
to effectively monitor and mobilize multiple agencies and financial resources in
response to national emergencies. This program is the largest WindowsNT
implementation in the Federal government and we believe it is the most
comprehensive emergency management system available. In addition, we believe
there is significant potential for generating additional revenues based on the
knowledge we have acquired in designing and integrating this system and its wide
applicability to other government agencies and projects. Another example of our
work is the logistics system we developed for the U.S. Air Force called Cargo
Movement Operation System ("CMOS"). CMOS tracks all equipment and cargo movement

                                       1
<PAGE>
operations for the Air Force world wide. This system is the first standard U.S.
Air Force client/server application to be installed. CMOS is currently installed
at air bases worldwide, and was recently chosen by the Office of the Secretary
of Defense to be the model transportation system for the Department of Defense.
As a result of developing and integrating CMOS, we were awarded another major
logistics automation contract to develop a model logistics system to manage the
transportation requirements of all branches of the U.S. armed forces.

COMPETITIVE STRENGTHS

    We attribute our growth and performance to several factors, including the
following:

    - BROAD ENGINEERING AND INFORMATION TECHNOLOGY CAPABILITIES. We have
      developed comprehensive information technology and engineering expertise
      and capabilities over our 22-year history of providing support for
      critical applications within the Federal government's military and
      intelligence infrastructure. Our employees are highly trained, enabling us
      to provide services for many complex governmental systems, including
      defense, intelligence, emergency response, logistics support and financial
      management.

    - LEADING FEDERAL GOVERNMENT SYSTEMS INTEGRATOR AND STRONG REPUTATION. We
      believe that the Federal government primarily uses three criteria in
      seeking suppliers of technical systems and services: the ability to
      deliver a broad range of sophisticated technical capabilities; a track
      record of excellence in servicing the needs of the Federal government; and
      the ability to deliver at a competitive price. Based on these criteria, we
      have developed a reputation as a premier provider to the Federal
      government and we have received numerous awards for our broad technical
      expertise and consistently high quality performance. In March, 1999 we
      were ranked as the No. 1 systems integrator in a survey of over 1,200
      Federal government customers by FEDERAL COMPUTER WEEK, a leading
      publication in the Federal government information technology sector. We
      believe that our demonstrated capabilities and reputation for service
      excellence have allowed us to maintain our position as an incumbent
      service provider on 100% of our major contracts that have been recompeted
      over the past three years.

    - DIVERSE CUSTOMER AND CONTRACT BASE; STRONG INCUMBENT POSITIONS. We have a
      diverse customer base with hundreds of governmental clients worldwide,
      which has included all 14 Cabinet-level agencies and all branches of the
      military. In 1998 we performed work on approximately 3,000 task orders,
      and since 1996 we have completed approximately 7,000 task orders for our
      clients. In executing these orders, we have acquired extensive knowledge
      of the particular information technology needs of our clients, and we
      believe that our typical position as the incumbent designer and integrator
      enables us to anticipate their changing technical requirements. These
      factors often position us as the preferred provider of ongoing support,
      upgrades and next generation systems development. As a result of these
      relationships we have developed a backlog of approximately $1.3 billion
      (and, after giving pro forma effect to the Acquisition, a backlog of $2.1
      billion as of June 30, 1999), providing significant predictability of
      revenues. For a further discussion of management's calculation of our
      backlog, please refer to the section in this prospectus entitled
      "Business--Backlog."

    - STRONG OPERATIONS MANAGEMENT; LOW COST STRUCTURE. Our focus on control of
      indirect costs and cost center flexibility has permitted us to increase
      profitability and we believe that we have achieved one of the lowest cost
      structures in the industry. Management has developed rigorous control
      procedures to mitigate losses in "at risk" situations where task order
      performance has commenced but funding or appropriation has not been
      formally authorized or where contract performance has begun because
      management considers the award of a contract to be imminent. We also
      employ management information and resource management systems to maximize
      operational efficiency and reduce indirect costs. Our indirect costs have
      been reduced to 15% of revenues in 1998 compared to an industry peer group
      average estimated by management to be between 18% to 20%,

                                       2
<PAGE>
      and we have increased EBITDA margins from 1.9% in 1995 to 6.6% in 1998,
      after giving pro forma effect to the Techmatics acquistion.

    - WELL-POSITIONED TO CAPITALIZE ON INDUSTRY GROWTH. Federal government
      information technology spending will total approximately $30 billion in
      1999 according to the Office of Management and Budget and is expected to
      increase to $35.1 billion in 2002. In addition, the outsourced portion of
      this spending is expected to increase from 78% in 1998 to 86% in 2002. Due
      to this increased outsourcing, the amount of information technology
      services procured from contractors is estimated to increase at 6.9% per
      year from 1998 to 2002. Anteon believes that growth in Federal government
      information technology spending will be driven by government downsizing,
      increased outsourcing and increasing attempts to utilize more efficient
      means of procurement. We expect a significant portion of this growth to be
      derived from major government-wide acquisition contract vehicles, such as
      the $25 billion GSA ANSWER multiple-award contract and the $10 billion
      Department of Transportation ITOP II multiple-award contract. We are one
      of a limited number of qualified suppliers under both of these major
      contract vehicles. We believe that our size, capabilities, reputation and
      long-standing relationships combined with our position as incumbent
      supplier to many Federal government agencies, position us to capitalize on
      the opportunities presented by these industry trends.

    - STRONG MANAGEMENT AND HIGHLY EXPERIENCED BOARD. Each of the five senior
      members of Anteon's management team has over 20 years of experience in
      managing both small and large companies in both the defense and commercial
      markets. In addition, several members of management and the Board of
      Directors are former military officers or senior government officials who
      are familiar with the information technology requirements of government
      agencies. Dr. Paul Kaminski, a director of Anteon, recently served as
      Under Secretary of Defense for Acquisition and Technology. Mr. Gilbert
      Decker, a Director of Anteon, recently served as Assistant Secretary of
      the U.S. Army for Research, Development and Acquisition, and in that
      capacity led the Army's acquisition and procurement reform efforts. Our
      management team is responsible for our growth and improved profitability
      in the current procurement environment and has a significant equity stake
      in Anteon through direct investment and equity-based incentives.

BUSINESS STRATEGY

    We believe that a key element of Anteon's success is its high standard of
performance and customer service. Past performance is one of the three critical
elements the government employs to evaluate information technology suppliers.
Our demonstrated performance record and service excellence have enabled us to
maintain our position as an incumbent service provider on 100% of our major
contracts that have been recompeted over the past three years. We believe that
our high-level technical abilities and low cost structure will allow us to
further expand our customer base, improve our operating results and continue to
grow. Specifically, we will pursue the following business strategies:

    - BROADEN CAPABILITIES. We continually seek to acquire new expertise and
      keep pace with developments in technology by acquiring and training our
      employees and acquiring technologies to complement our skill set. We are
      aggressively pursuing several new disciplines that complement our existing
      technology capabilities. Particular areas of expertise we are pursuing
      include network communications, remote sensor information processing,
      geographic information systems and information security. We also seek to
      broaden our technology skills by providing extensive training to new and
      current employees. For example, we have an extensive in-house,
      computer-based training program consisting of over 150 courses. These
      efforts will enable us to remain at the forefront of information
      technology applications and be more responsive and flexible in servicing
      the needs of our customers.

                                       3
<PAGE>
    - LEVERAGE EXPERIENCE AND REPUTATION TO EXPAND MARKET SHARE. We have
      performed a variety of services for a diverse base of customers, including
      hundreds of governmental clients worldwide, including all Cabinet-level
      agencies and all branches of the military. The new Federal government
      procurement environment has reduced the number of suppliers and favors
      those companies with experience and broad capabilities. We plan to
      leverage our comprehensive capabilities and our position as the incumbent
      provider on critical Federal government applications to provide complete
      end-to-end services including new systems development, integration,
      upgrades, maintenance, support and training. To support our plans, we have
      increased our national and global presence, opening offices in
      Albuquerque, New Mexico; Colorado Springs, Colorado; Australia and Asia.
      We have also acquired a comprehensive new business development and bidding
      software system, known as WinAward, which scans for and targets new
      programs or task orders which require skills and services particularly
      suited to Anteon's capabilities. This system provides early identification
      of prospects, allowing us to mobilize the resources necessary to win the
      award.

    - CONTINUE TO IMPROVE OPERATING AND FINANCIAL PERFORMANCE. We believe that a
      key element of our success in the Federal government market has been our
      continuous pursuit of cost reductions and focus on working capital
      management. We have developed and employ integrated management information
      and resource management systems and policies that have enabled us to
      maintain indirect cost levels that we believe are among the lowest in the
      industry. We will continue to leverage our operating efficiency and risk
      management capabilities to bid aggressively on contracts to further
      improve our operating and financial performance.

    - PURSUE STRATEGIC ACQUISITIONS. We believe the changes in the government
      procurement market will result in continuing consolidation opportunities.
      We will selectively review acquisition candidates with a focus on
      companies having complementary skills and established positions in key
      segments of the marketplace that provide opportunities for revenue
      enhancement or a reduction in indirect costs. A key element of all
      acquisitions is the existence of rigorous risk management procedures and
      strong operational management.

                                THE TRANSACTIONS

    On March 7, 1999, Anteon entered into a definitive merger agreement to
acquire all of the issued and outstanding shares of common stock of A&T at a
price of $26.00 per share. We consummated the acquisition on June 23, 1999 after
the approval of the acquisition by the stockholders of A&T. In connection with
the acquisition, Anteon received an equity contribution of $22.5 million from
affiliates of Caxton-Iseman Capital, Inc. In addition, in connection with the
acquisition we entered into a new credit facility in an aggregate principal
amount of $180.0 million, a portion of which was used to repay all of the
amounts previously outstanding under Anteon's and A&T's credit facilities. For
purposes of this prospectus, the "Transactions" refers to the acquisition, the
issuance of the initial notes, the equity contribution, the borrowings under the
new credit facility in connection with the Acquisition and the repayment of the
outstanding debt under the current credit facilities of A&T and Anteon.

    Caxton-Iseman Capital is a New York based private equity investment company
founded in 1993. Caxton-Iseman Capital currently manages a $600 million private
investment fund on behalf of a select group of limited partners and seeks to
invest with management of companies positioned for growth in a variety of
industries. Caxton-Iseman Capital has made investments in eleven companies
including Magnavox Electronic Systems, Inc., Leisure Link Holdings and Glass's
Group.

                               These covenants are subject to important exceptions and
                               qualifications, which are described in the "Description of

Federal Income Tax Considera-
  tions Relating to the
  Exchange Offer.............  Exchanging your initial notes for exchange notes will not be
                               a taxable event to you for United States federal income tax
                               purposes. Please refer to the section of this prospectus
                               entitled "Certain United States Federal Income Tax
                               Considerations."

Absence of a Public Market
  for the Exchange Notes.....  The exchange notes are new securities with no established
                               market for them. We cannot assure you that a market for
                               these notes will develop or that this market will be liquid.

Form of the Exchange Notes...  The exchange notes will be represented by one or more
                               permanent global securities in bearer form deposited on
                               behalf of The Depository Trust Company with IBJ Whitehall
                               Bank & Trust Company, as custodian. You will not receive
                               exchange notes in registered form unless one of the events
                               described in the section of this prospectus entitled

                               will be shown on, and transfers of these notes will be
                               effected only through, records maintained in book-entry form
                               by The Depository Trust Company with respect to its
                               participants. Initial notes issued in certificated form may
                               be exchanged for beneficial interests in the global
                               securities.

- ------------------------

(a) Cash interest expense excludes the noncash portion of interest expense.

(b) EBITDA represents earnings before interest, taxes and depreciation and
    amortization. EBITDA also excludes infrequent and unusual charges of $0.1
    million for the year ended December 31, 1998 relating to asset write-offs at
    Techmatics, and $0.24 million for the six months ended June 30, 1999
    relating to a settlement with a former executive. Management believes that
    these charges will not recur and will not result in future cash charges.
    EBITDA is presented because we believe that it is a widely accepted
    supplemental indicator of an entity's ability to incur and service debt.
    However, EBITDA should not be considered by an investor as an alternative to
    net income or operating income as an indicator of our operating performance
    or cash flow from operations, or as an alternative to cash flows as a
    measure of liquidity.

(c) Management believes that additional cost savings of $3.7 million will be
    generated through reduced general and administrative expenses and the
    allocation of a portion of Anteon's corporate expenses to A&T. Anteon's
    Adjusted EBITDA equals pro forma EBITDA plus the following adjustments:

        ANTEON INDIRECT COSTS REDUCTIONS.  Anteon has reduced indirect personnel
    (I.E., personnel not directly engaged in contract performance) saving
    approximately $1.2 million in total salary expense. In addition, on January
    1, 1999 Anteon replaced Techmatics' employee benefits programs with its own
    employee benefits programs to ensure consistency in benefits among its
    employees. These new programs have resulted in savings of approximately $1.0
    million per year. In 1999, Anteon closed a Techmatics office facility and
    further reduced indirect overhead which produced combined savings of $1.9
    million. Because the government previously reimbursed Anteon for a portion
    of these expenses under cost-plus contracts, Anteon and the government will
    share in the benefit of the expense reduction with Anteon realizing $1.2
    million for the year ended December 31, 1998 and $0.2 million for the six
    months ended June 30, 1999 of additional EBITDA and the government realizing
    $2.9 million of lower costs annually.

        INCREASE IN BILLABLE INDIRECT COSTS.  After giving pro forma effect to
    the acquisition of A&T, the level of billable indirect costs under our
    contracts will increase because the proportion of our revenues generated by
    cost-plus contracts will increase from 40% to 55%. This adjustment to
    indirect billable costs is determined pursuant to government regulations and
    accounting standards. As a result of this adjustment, Anteon will be
    permitted to bill the government for a greater portion of its indirect
    costs. Based on our ability to pass such indirects costs through to our
    government customers, we estimate this will result in an additional
    reimbursable costs of $2.5 million for the year ended December 31, 1998 and
    $1.2 million for the six months ended June 30, 1999. As management
    implements cost reductions following the acquisition, these savings will be
    passed through to our customers.

    There can be no assurances, however, that the projected cost savings
    outlined above will be achieved.


    KPMG LLP has not examined, reviewed or compiled adjusted EBITDA or its
    composition, and therefore expresses no form of assurance on such amounts.


(d) Represents the ratio of net debt to Adjusted EBITDA using net debt as of
    June 30, 1999 and Adjusted EBITDA for the year ended December 31, 1998.

            SUMMARY CONSOLIDATED FINANCIAL DATA--ANTEON CORPORATION

    The following summary consolidated financial data has been derived from (1)
in the case of Anteon, its unaudited consolidated financial statements as of
June 30, 1999 and for the six months ended June 30, 1999 and 1998 and its
audited consolidated financial statements for the years ended December 31, 1998
and 1997 and for the period from April 1, 1996 to December 31, 1996 and (2) in
the case of Ogden Professional Services Corporation (the "Predecessor Company"),
its audited consolidated financial statements for the period from January 1,
1996 to March 31, 1996. In the opinion of management, the unaudited consolidated
financial statements include all adjustments, consisting of normal recurring
accruals, that are necessary for a fair presentation of the financial position
and results of operations for these periods. Each of the audited consolidated
financial statements of Anteon and our Predecessor Company have been audited by
KPMG LLP, independent certified public accountants. The results of operations
for each period presented below are not comparable to the prior period as a
result of business acquisitions consummated in 1997, 1998 and 1999. Results of
operations of these acquired businesses are included in Anteon's consolidated
financial statements for the periods subsequent to the respective dates of
acquisition. You should read the following information in conjunction with
"Capitalization," "Unaudited Pro Forma Condensed Consolidated Financial Data,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Anteon Corporation," "Business" and the historical consolidated
financial statements of Anteon, together with the notes thereto, included
elsewhere in this prospectus.

(a) Represents the results of operations and financial position of our
    Predecessor Company prior to its acquisition by Anteon.

(b) Represents the write-off of $772 of deferred financing fees, net of income
    taxes of $309, related to the existing credit facility which was repaid
    early in conjunction with the Transactions.

(c) EBITDA represents earnings before interest, taxes and depreciation and
    amortization. EBITDA also excludes a one-time noncash, nonrecurring charge
    of $0.1 million relating to asset write-offs at Techmatics. Management
    believes that these charges will not recur and will not result in future
    cash charges. EBITDA is presented because we believe that it is a widely
    accepted supplemental indicator of an entity's ability to incur and service
    debt. However, EBITDA should not be considered by an investor as an
    alternative to net income or operating income as an indicator of our
    operating performance or cash flow from operations, or as an alternative to
    cash flows as a measure of liquidity.

(d) For purposes of this computation, earnings are defined as losses plus fixed
    charges. Fixed charges are the sum of (i) interest expensed and capitalized,
    (ii) amortization of deferred financing costs, premium and debt discounts,
    (iii) the portion of operating lease rental expense that is representative
    of the interest factor (deemed to be one-third) and (iv) dividends on
    preferred stock.

                                  RISK FACTORS

    BEFORE YOU TENDER THE INITIAL NOTES IN THE EXCHANGE OFFER, YOU SHOULD
CAREFULLY CONSIDER THESE RISK FACTORS, AS WELL AS THE OTHER INFORMATION
CONTAINED IN THIS PROSPECTUS. THE RISKS DESCRIBED BELOW ARE NOT THE ONLY ONES
FACING OUR COMPANY. ADDITIONAL RISKS NOT PRESENTLY KNOWN TO US OR THAT WE
CURRENTLY DEEM IMMATERIAL MAY ALSO IMPAIR OUR BUSINESS OPERATIONS. CERTAIN
STATEMENTS IN THIS PROSPECTUS (INCLUDING CERTAIN OF THE FOLLOWING RISK FACTORS)
CONSTITUTE FORWARD-LOOKING STATEMENT. SEE "FORWARD-LOOKING STATEMENTS."

RISK FACTORS RELATING TO THE NOTES

    SUBSTANTIAL LEVERAGE--OUR SUBSTANTIAL INDEBTEDNESS COULD AVERSELY AFFECT OUR
FINANCIAL HEALTH AND PREVENT US FROM FULFILLING OUR OBLIGATIONS UNDER THE NOTES.

    We have a significant amount of debt outstanding. You should be aware that
this level of debt could have important consequences to you as a holder of the
notes. Below we have identified for you some of the material potential
consequences resulting from this significant amount of debt.

    - We may be unable to obtain additional financing for working capital,
      capital expenditures, acquisitions and general corporate purposes.

    - A significant portion of our cash flow from operations must be dedicated
      to the repayment of indebtedness, thereby reducing the amount of cash we
      have available for other purposes.

    - Our ability to adjust to changing market conditions may be hampered. We
      may be more vulnerable in a volatile market.

    ADDITIONAL BORROWINGS AVAILABLE--DESPITE CURRENT INDEBTEDNESS LEVELS, WE AND
OUR SUBSIDIARIES MAY STILL BE ABLE TO INCUR SUBSTANTIALLY MORE DEBT. THIS COULD
FURTHER EXACERBATE THE RISKS DESCRIBED ABOVE.

    We and our subsidiaries may be able to incur additional indebtedness in the
future. The terms of the Indenture limit but do not prohibit us or our
subsidiaries from doing so. Our new credit facility currently permits additional
borrowings of up to $53.4 million, based on our current borrowing base and ratio
of net debt to EBITDA (as defined in the new credit facility) and amounts
currently outstanding under the revolving credit facility, and any such
borrowings will be senior to the notes and the Subsidiary Guarantees (as defined
in "Description of the Notes--Certain Definitions"). If new debt is added by us
or our subsidiaries, the related risks that we and they now face could
intensify. Please refer to the sections in this prospectus entitled
"Capitalization," "Selected Consolidated Financial Data," "Description of Other
Material Agreements--New Credit Facility" and "Description of the Notes."

    ABILITY TO SERVICE DEBT--TO SERVICE OUR INDEBTEDNESS, WE WILL REQUIRE A
SIGNIFICANT AMOUNT OF CASH. OUR ABILITY TO GENERATE CASH DEPENDS ON MANY FACTORS
BEYOND OUR CONTROL.

    You should be aware that our ability to repay or refinance our debt depends
on our successful financial and operating performance. We cannot assure you that
our business strategy will succeed or that we will achieve our anticipated
financial results. Our financial and operational performance depends upon a
number of factors, many of which are beyond our control. These factors include:

    - the current economic and competitive conditions in the information
      technology industry;

    - Federal government spending levels, both generally and by our particular
      customers;

    - any operating difficulties, operating costs or pricing pressures we may
      experience;

    - the passage of legislation or other regulatory developments that affects
      us adversely; and

    - any delays in implementing any strategic projects we may have.

    We cannot assure you that we will generate sufficient cash flow from
operations or that we will be able to obtain sufficient funding to satisfy all
of our obligations, including the notes. Our ratio of EBITDA to total cash
interest expense for the six months ended June 30, 1999 would have been 2.3 to
1.0. If we are

                                       15
<PAGE>
unable to pay our debts, we will be required to pursue one or more alternative
strategies, such as selling assets, refinancing or restructuring our
indebtedness or selling additional equity capital. However, we cannot assure you
that any alternative strategies will be feasible at the time or prove adequate.
Also, certain alternative strategies would require the consent of our senior
secured lenders before we engage in any such strategy. Please refer to the
sections in this prospectus entitled "Description of Other Material Agreements"
and "Description of the Notes."

    SUBORDINATION--YOUR RIGHT TO RECEIVE PAYMENTS ON THE NOTES IS JUNIOR TO A
SIGNIFICANT PORTION OF OUR GUARANTORS' EXISTING INDEBTEDNESS AND POSSIBLY ALL OF
OUR FUTURE BORROWINGS. FURTHER, THE CLAIMS OF CREDITORS OF OUR NON-GUARANTOR
SUBSIDIARIES WILL HAVE PRIORITY WITH RESPECT TO THE ASSETS AND EARNINGS OF SUCH
SUBSIDIARIES OVER YOUR CLAIMS.

    The notes and the Subsidiary Guaranties will be subordinated to the prior
payment in full of our and the Subsidiary Guarantors' (as defined in
"Description of the Notes--Certain Definitions") current and future Senior
Indebtedness. As of June 30, 1999, we had $73.0 million outstanding under our
new credit facility and the Subsidiary Guarantors had $73.0 million of Senior
Indebtedness (consisting solely of their Senior Guaranty of our obligations
under the new credit facility). Because of the subordination provisions of the
notes, in the event of the bankruptcy, liquidation or dissolution of our company
or any subsidiary guarantor, our assets or the assets of the Subsidiary
Guarantors would be available to pay obligations under the notes only after all
payments had been made on our or the Subsidiary Guarantors' Senior Indebtedness.
We cannot assure you that sufficient assets will remain after all such payments
have been made to make any payments on the notes, including payments of interest
when due.

    We conduct a portion of our business through our subsidiaries. Any future
domestic subsidiary that does not incur indebtedness and all of our foreign
subsidiaries will not be guaranteeing the notes. Claims of creditors or our
non-guarantor subsidiaries, including trade creditors, secured creditors and
creditors holding indebtedness or guaranties issued by such subsidiaries, will
generally have priority with respect to the assets and earnings of such
subsidiaries over the claims of creditors of our company, including holders of
the notes, even if the obligations of such subsidiaries do not constitute Senior
Indebtedness. As of June 30, 1999, after eliminating intercompany activity, our
subsidiaries that are not Subsidiary Guarantors would have 0.4% of our
consolidated liabilities and assets, respectively.

    Please refer to the sections in this prospectus entitled "Description of the
Notes--Ranking" and "Description of the Notes--Certain Covenants--Limitations on
Indebtedness."

    RESTRICTIVE DEBT COVENANTS--THE TERMS OF OUR NEW CREDIT FACILITY AND THE
INDENTURE IMPOSE SIGNIFICANT RESTRICTIONS ON OUR ABILITY AND THAT OF OUR
SUBSIDIARIES TO TAKE CERTAIN ACTIONS, WHICH MAY HAVE AN IMPACT ON OUR BUSINESS,
RESULTS OF OPERATIONS AND FINANCIAL CONDITION.

    The indenture and our new credit facility will impose significant operating
and financial restrictions on us and our subsidiaries and require us to meet
certain financial tests. These restrictions may significantly limit or prohibit
us from engaging in certain transactions, including the following:

    - incurring or guaranteeing additional indebtedness;

    - paying dividends or other distributions to our stockholders or redeeming,
      repurchasing or retiring our capital stock or subordinated obligations;

    - making investments;

    - creating liens on our assets;

    - issuing or selling capital stock of our subsidiaries;

    - transforming or selling assets currently held by us;

    - engaging in transactions with affiliates; and

    - engaging in mergers or consolidations.

                                       16
<PAGE>
    The failure to comply with any of these covenants would cause a default
under the indenture and our other debt agreements. A default, if not waived,
could result in acceleration of our indebtedness, in which case the debt would
become immediately due and payable. If this occurs, we may not be able to repay
our debt or borrow sufficient funds to refinance it. Even if new financing is
available, it may not be on terms that are acceptable to us. Complying with
these covenants may cause us to take actions that are not favorable to holders
of the notes. Please refer to the sections in this prospectus entitled
"Description of Other Material Agreements" and "Description of the
Notes--Certain Covenants".

    LIMITATIONS ON SUBSIDIARY GUARANTIES--THE GUARANTIES PROVIDED BY OUR
SUBSIDIARIES ARE SUBJECT TO CERTAIN DEFENSES WHICH MAY LIMIT YOUR RIGHT TO
RECEIVE PAYMENT ON THE NOTES AND ARE SUBORDINATED TO THE RIGHTS OF OTHER
CREDITORS OF SUCH SUBSIDIARY GUARANTORS.

    Although the Subsidiary Guaranties provide the holders of the notes with a
direct claim against the assets of the Subsidiary Guarantors, enforcement of the
Subsidiary Guaranties against any Subsidiary Guarantor would be subject to
certain "suretyship" defenses available to guarantors generally. Enforcement
could also be subject to other defenses available to the Subsidiary Guarantors
in some circumstances. Please refer to the section in this prospectus entitled
"--Fraudulent Conveyance Matters." To the extent that the Subsidiary Guaranties
are not enforceable, the notes and Subsidiary Guaranties would be effectively
subordinated to all liabilities of the Subsidiary Guarantors, including trade
payables of such Subsidiary Guarantors, whether or not such liabilities
otherwise would constitute Senior Indebtedness under the indenture. In addition,
the payment of dividends to us by our subsidiaries is contingent upon the
earnings of those subsidiaries and approval of those subsidiaries.

    FRAUDULENT CONVEYANCE MATTERS--FEDERAL AND STATE STATUTES ALLOW COURTS,
UNDER SPECIFIC CIRCUMSTANCES, TO VOID THE NOTES AND THE SUBSIDIARY GUARANTIES
AND REQUIRE NOTEHOLDERS TO RETURN PAYMENTS RECEIVED FROM ANTEON OR THE
SUBSIDIARY GUARANTORS.

    An unpaid creditor or representative of creditors, such as a trustee in
bankruptcy or Anteon as a debtor-in-possession in a bankruptcy proceeding, could
file a lawsuit claiming that the issuance of the notes constituted a "fraudulent
conveyance." To make such a determination, a court would have to find that we
did not receive fair consideration or reasonably equivalent value for the notes,
and that, at the time the notes were issued, we:

    - were insolvent;

    - were rendered insolvent by the issuance of the notes;

    - were engaged in a business or transaction for which our remaining assets
      constituted unreasonably small capital; or

    - intended to incur, or believed that we would incur, debts beyond our
      ability to pay such debts as they matured.

    If a court were to make such a finding, it could void our obligations under
the notes, subordinate the notes to our other indebtedness or take other actions
detrimental to you as a holder of the notes.

    The measure of insolvency for these purposes will vary depending upon the
law of the jurisdiction being applied. Generally, however, a company will be
considered insolvent for these purposes if the sum of that company's debts is
greater than the fair value of all of that company's property, or if the present
fair saleable value of that company's assets is less than the amount that will
be required to pay its probable liability on its existing debts as they mature.
Moreover, regardless of solvency, a court could void an incurrence of
indebtedness, including the notes, if it determined that the transaction was
made with intent to hinder, delay or defraud creditors, or a court could
subordinate the indebtedness, including the notes, to the claims of all existing
and future creditors on similar grounds. We cannot determine in advance what
standard a court would apply to determine whether we were "insolvent" in
connection with the sale of the notes.

                                       17
<PAGE>
    The making of the Subsidiary Guaranties might also be subject to similar
review under relevant fraudulent conveyance laws if a bankruptcy, reorganization
or rehabilitation case or a lawsuit (including circumstances in which bankruptcy
is not involved) were commenced by, or on behalf of, unpaid creditors of the
Subsidiary Guarantors at some future date. A court could impose legal and
equitable remedies, including subordinating the obligations under the subsidiary
guaranties, directing the repayment of any amounts paid from the proceeds of the
Subsidiary Guaranties to a fund for the benefit of other creditors or taking
other actions detrimental to you as a holder of the notes.

    FINANCING CHANGE OF CONTROL OFFER--WE MAY NOT HAVE THE ABILITY TO RAISE THE
FUNDS NECESSARY TO FINANCE THE CHANGE OF CONTROL OFFER REQUIRED BY THE
INDENTURE.

    If a Change of Control (as defined in "Description of the Notes--Certain
Definitions") occurs, you have the right to require us to repurchase any or all
of the notes you own at a price equal to 101% of the principal amount thereof,
together with any interest we owe you. Upon a Change of Control, we may be
required immediately to repay the outstanding principal, any accrued interest on
the notes, any amounts owed by us under our new credit facility and other
indebtedness or preferred stock then outstanding. We cannot assure you that we
would be able to repay the amounts outstanding under our new credit facility or
the principal amount outstanding of our other indebtedness or shares of our
preferred stock, if applicable, or to obtain the necessary consents to purchase
the notes. Any requirement to offer to purchase any outstanding notes may result
in our having to refinance our outstanding indebtedness, which we may not be
able to do. In addition, even if we were able to refinance such indebtedness,
such financing may be on terms unfavorable to us. If we fail to repurchase all
of the notes tendered for purchase upon the occurrence of a Change of Control,
such failure will be an event of default under the indenture and under our new
credit facility.

    NO PRIOR MARKET FOR THE EXCHANGE NOTES--AN ACTIVE TRADING MARKET MAY NOT
DEVELOP FOR THE EXCHANGE NOTES.

    The exchange notes will be registered under the Securities Act but will not
be eligible for trading on the Private Offerings, Resales and Trading through
Automated Linkages market. The exchange notes will constitute a new issue of
securities with no established trading market, and there can be no assurance as
to:

    - the development of any market for the exchange notes,

    - the liquidity of any market for the exchange notes that may develop,

    - your ability to sell your exchange notes, or

    - the price at which would be able to sell your exchange notes.

    We have been advised by the initial purchasers for the initial notes that
they presently intend to make a market in the exchange notes. However, they are
not obligated to do so and may discontinue any market-making activity with
respect to the exchange notes at any time without notice. If a market for the
exchange notes were to exist, the exchange notes could trade at prices that may
be higher or lower than their principal amount or purchase price, depending on
many factors, including prevailing interest rates, the market for similar
debentures and the financial performance of Anteon and A&T. Historically, the
market for non-investment grade debt has been subject to disruptions that have
caused substantial volatility in the prices of securities similar to the
exchange notes. We cannot assure you that the market for the exchange notes, if
any, will not be subject to similar disruptions. Any disruption may adversely
affect you as a holder of the exchange notes.

    ISSUANCE OF THE EXCHANGE NOTES -- THE ISSUANCE OF THE EXCHANGE NOTES MAY
ADVERSELY AFFECT THE MARKET FOR THE INITIAL NOTES.

    Following commencement of the exchange offer, you may continue to trade the
initial notes in the Private Offerings, Resales and Trading through Automated
Linkages market. If initial notes are tendered for exchange and accepted in the
exchange offer, the trading market for the untendered and tendered but
unaccepted initial notes could be adversely affected.

                                       18
<PAGE>
    FAILURE TO PARTICIPATE IN THE EXCHANGE OFFER -- YOUR FAILURE TO PARTICIPATE
IN THE EXCHANGE OFFER WILL HAVE ADVERSE CONSEQUENCES.

    The initial notes were not registered under the Securities Act or under the
securities laws of any state and you may not resell them, offer them for resale
or otherwise transfer them unless they are subsequently registered or resold
under an exemption from the registration requirements of the Securities Act and
applicable state securities laws. If you do not exchange your initial notes for
exchange notes pursuant to the exchange offer, or if you do not properly tender
your initial notes in the exchange offer, you will not be able to resell, offer
to resell or otherwise transfer the initial notes unless they are registered
under the Securities Act. In addition, you will no longer be able to obligate us
to register the initial notes under the Securities Act except in the limited
circumstances provided under our registration rights agreement.

    DELIVERY OF A PROSPECTUS -- CERTAIN PERSONS WHO PARTICIPATE IN THE EXCHANGE
OFFER MUST DELIVER A PROSPECTUS IN CONNECTION WITH RESALES OF THE EXCHANGE
NOTES.

    Based on certain no-action letters issued by the staff of the Securities and
Exchange Commission, we believe that you may offer for resale, resell or
otherwise transfer the exchange notes without compliance with the registration
and prospectus delivery requirements of the Securities Act. However, in some
instances described in this prospectus under "The Exchange Offer," you will
remain obligated to comply with the registration and prospectus delivery
requirements of the Securities Act to transfer your exchange notes. In these
cases, if you transfer an exchange note without delivering a prospectus meeting
the requirements of the Securities Act or without an exemption from registration
of your exchange notes under this Act, you may incur liability under the
Securities Act. We do not and will not assume or indemnify you against this
liability.

RISKS ASSOCIATED WITH FEDERAL GOVERNMENT CONTRACTING

    FEDERAL GOVERNMENT CONTRACTING RISKS--OUR BUSINESS COULD BE ADVERSELY
AFFECTED IF THERE WERE ANY SIGNIFICANT CHANGES IN THE CONTRACTING POLICIES OR
FISCAL POLICIES OF THE U.S. FEDERAL GOVERNMENT.

    We derive substantially all of our revenues from contracts with the U.S.
Federal government or subcontracts under Federal government prime contracts, and
we believe that the success and development of our business will continue to
depend on our successful participation in Federal government contract programs.
Accordingly, changes in Federal government contracting policies could directly
affect our financial performance. Among the factors that could materially
adversely affect our Federal government contracting business are:

    - budgetary constraints affecting Federal government spending generally, or
      specific departments or agencies in particular, and changes in fiscal
      policies or available funding;

    - changes in Federal government programs or requirements;

    - curtailment of the Federal government's use of technology services firms;

    - the adoption of new laws or regulations;

    - technological developments;

    - Federal governmental shutdowns (such as that which occurred during the
      Federal government's 1996 fiscal year);

    - competition and consolidation in the information technology industry; and

    - general economic conditions.

These or other factors could cause Federal governmental agencies to reduce their
purchases under contracts, to exercise their right to terminate contracts or not
to exercise options to renew contracts, any of which could have a material
adverse effect on our financial condition, results of operations and debt
service capability.

                                       19
<PAGE>
    Many of our Federal government customers are subject to increasingly
stringent budgetary constraints. We have substantial contracts in place with
many Federal departments and agencies, and our continued performance under these
contracts, or award of additional contracts from these agencies, could be
materially adversely affected by spending reductions or budget cutbacks at these
agencies. Please refer to the section in this prospectus entitled "Overview of
Federal Government Contracting." Such reductions or cutbacks could have a
material adverse effect on our financial condition, results of operations and
debt service capability.

    EARLY TERMINATION OF CONTRACTS--WE ARE NOT ABLE TO GUARANTEE THAT OUR
CONTRACTS WITH THE U.S. FEDERAL GOVERNMENT AND SUBCONTRACTS UNDER FEDERAL
GOVERNMENT PRIME CONTRACTS WILL NOT BE TERMINATED PRIOR TO THEIR COMPLETION AND
THERE IS NO GUARANTEE THAT WE WILL RETAIN THESE CONTRACTS IN ANY COMPETITIVE
REBIDDING PROCESS.

    We derive substantially all of our revenues from U.S. Federal government
contracts and subcontracts under Federal government prime contracts that
typically span one or more base years and one or more option years and are
awarded through formal competitive bidding processes. Many of the option periods
cover more than half of the contract's potential duration. Federal government
agencies generally have the right not to exercise these option periods. In
addition, our contracts typically also contain provisions permitting a
government client to terminate the contract on short notice, with or without
cause. A decision not to exercise option periods or to terminate contracts would
reduce the profitability of these contracts to us. Our contractual costs and
revenues are subject to adjustment as a result of Federal government audits.
Please refer to the section in this prospectus entitled "--Contracts Subject to
Audit."

    Upon expiration, if the customer requires further services of the type
provided in the contract, there is frequently a competitive rebidding process,
and there can be no assurance that we will win any particular bid, or that we
will be able to replace business lost upon expiration or completion of a
contract. Further, all Federal government contracts are subject to protest by
competitors. The unexpected termination of one or more of our significant
contracts could result in significant revenue shortfalls. The termination or
nonrenewal of any of our significant contracts, short-term revenue shortfalls,
the imposition of fines or damages or our suspension or debarment from bidding
on additional contracts could have a material adverse effect on our financial
condition, results of operations and debt service capability. For a description
of some of our material contracts, please refer to the sections in this
prospectus entitled "Business-- Anteon Divisions" and "Business--A&T Divisions."

    CONTRACTS SUBJECT TO AUDIT--OUR BUSINESS COULD BE ADVERSELY AFFECTED BY A
NEGATIVE AUDIT BY THE DEFENSE CONTRACT AUDIT AGENCY. WE COULD BE REQUIRED TO
REIMBURSE THE U.S. FEDERAL GOVERNMENT FOR COSTS THAT WE HAVE EXPENDED ON OUR
CONTRACTS AND OUR ABILITY TO COMPETE SUCCESSFULLY FOR FUTURE CONTRACTS COULD BE
MATERIALLY IMPAIRED.

    The Defense Contract Audit Agency, which we refer to as "DCAA" and certain
other government agencies, routinely audit and investigate government contracts.
These agencies review a contractor's performance on its contract, pricing
practices, cost structure and compliance with applicable laws, regulations and
standards. Any costs found to be improperly allocated to a specific contract
will not be reimbursed, while costs already reimbursed must be refunded.
Therefore, a DCAA audit could result in a substantial adjustment to our
revenues. No material adjustments have resulted from any DCAA audits of us
completed as of December 31, 1996, and we believe that adjustments resulting
from subsequent audits will not adversely affect our business. If a government
audit uncovers improper or illegal activities, we may be subject to civil and
criminal penalties and administrative sanctions, including termination of
contracts, forfeitures of profits, suspension of payments, fines and suspension
or debarment from doing business with the Federal government. In addition, we
could suffer serious reputational harm if allegations of impropriety were made
against us. Any such government determination of impropriety or illegality, or
allegation of impropriety, could have a material adverse effect on our financial
condition, results of operations and debt service capabilities.

                                       20
<PAGE>
    RISKS UNDER IDIQ CONTRACTS AND GSA SCHEDULE CONTRACT VEHICLES--MANY OF OUR
U.S. FEDERAL GOVERNMENT CUSTOMERS SPEND THEIR PROCUREMENT BUDGETS THROUGH GSA
SCHEDULE CONTRACTS AND WE ARE REQUIRED TO COMPETE FOR POST-AWARD ORDERS.

    Budgetary pressures and reforms in the procurement process have caused many
U.S. Federal government customers to increasingly purchase goods and services
through "indefinite delivery, indefinite quantity", which we refer to as "IDIQ",
contracts, General Service Administration, which we refer to as "GSA", Schedule
contracts and other multiple award and/or government-wide acquisition contract
vehicles. These contract vehicles have resulted in increased competition and
pricing pressure requiring that we make sustained post-award efforts to realize
revenues under the relevant contract. There can be no assurance that we will
continue to increase revenues or otherwise sell successfully under these
contract vehicles. Our failure to compete effectively in this procurement
environment could have a material adverse effect on our financial condition,
results of operations and debt service capability. For a description of some of
our material contracts, please refer to the sections in this prospectus entitled
"Business--Anteon Divisions" and "Business--A&T Divisions."

RISK FACTORS RELATING TO THE INDUSTRY

    GOVERNMENT REGULATIONS--WE MAY BE LIABLE FOR PENALTIES UNDER A VARIETY OF
PROCUREMENT RULES AND REGULATIONS. CHANGES IN GOVERNMENT REGULATIONS COULD
ADVERSELY AFFECT OUR BUSINESS.

    Our defense and commercial businesses must comply with and are affected by
various government regulations. Among the most significant regulations are the
Federal Acquisition Regulations, which comprehensively regulate the formation,
administration and performance of government contracts; the Truth in
Negotiations Act, which requires certification and disclosure of all cost and
pricing data in connection with contract negotiations; the Cost Accounting
Standards, which impose accounting requirements that govern our right to
reimbursement under certain cost-based government contracts; and laws,
regulations and Executive Orders restricting the use and dissemination of
information classified for national security purposes and the exportation of
certain products and technical data. These regulations affect how our customers
and we can do business and, in some instances, impose added costs on our
businesses. Any changes in applicable laws could adversely affect the financial
performance of the business affected by the changed regulations. Any failure to
comply with applicable laws could result in contract termination, price or fee
reductions or suspension or debarment from contracting with the Federal
government.

    RISKS RELATING TO FURTHER REDUCTIONS OR CHANGES IN MILITARY EXPENDITURES--A
DECLINE IN THE U.S. DEFENSE BUDGET MAY ADVERSELY AFFECT OUR OPERATIONS.

    Sales under contracts with the U.S. Government's Department of Defense,
including under subcontracts that identified the Department of Defense as the
ultimate purchaser, represented approximately 34% of our sales in 1998. The U.S.
defense budget has generally declined since the mid-1980s, resulting in a
slowing of new program starts, program delays and program cancellations. This
reduction in the U.S. defense budget has caused most defense-related government
contractors to experience declining revenues, increased pressure on operating
margins and, in some cases, net losses.

    The loss or significant curtailment of our material U.S. or international
military contracts or the failure to renew or replace material contracts upon
expiration or completion or a general significant decline in military
expenditures, could materially and adversely affect our financial condition,
results of operations and debt service capability.

RISK FACTORS RELATING TO ANTEON AND A&T

    BACKLOG--WE ARE NOT ABLE TO GUARANTEE THAT CONTRACT ORDERS IN OUR OR A&T'S
BACKLOG WILL RESULT IN ACTUAL REVENUES IN ANY PARTICULAR FISCAL PERIOD.

                                       21
<PAGE>
    There can be no assurance that our or A&T's backlog will result in actual
revenues in any particular period or at all. Further, there can be no assurance
that any contract included in backlog that generates revenue will be profitable.
Our backlog consists of "funded" backlog which is based upon amounts actually
appropriated by a customer for payment of goods and services and "unfunded"
backlog which is based upon management's estimate of the future potential of our
existing contracts to generate revenues for us. These estimates are based on our
experience under such contracts and similar contracts, and management believes
such estimates to be reasonable. However, there can be no assurances that all of
such backlog will be recognized as revenue.

    In addition, the Federal government's ability to select multiple winners
under IDIQ contracts, as well as its right to award subsequent task orders to
any particular awardee, means that there is no assurance that unfunded contract
backlog will result in actual orders. Further, the Federal government enjoys
broad rights to unilaterally modify or terminate such contracts. Accordingly,
most of our and A&T's backlog is subject to modification and termination at the
Federal government's discretion. In addition, funding for orders from the
Federal government is subject to approval on an annual basis by Congress
pursuant to the appropriations process.

    RELIANCE ON SUBCONTRACTORS--WE REGULARLY EMPLOY SUBCONTRACTORS TO ASSIST US
IN SATISFYING OUR CONTRACTUAL OBLIGATIONS. IF THESE SUBCONTRACTORS FAIL TO
PERFORM THEIR CONTRACTUAL OBLIGATIONS, OUR PRIME CONTRACT PERFORMANCE AND OUR
ABILITY TO OBTAIN FUTURE BUSINESS COULD BE MATERIALLY AND ADVERSELY IMPACTED.

    Our performance of government contracts may involve the issuance of
subcontracts to other companies upon which we rely to perform all or a portion
of the work we are obligated to deliver to our customers. A failure by one or
more of our subcontractors to satisfactorily deliver on a timely basis the
agreed-upon supplies and/or perform the agreed-upon services may materially and
adversely impact our ability to perform our obligations as a prime contractor.
In extreme cases, such subcontractor performance deficiencies could result in
the government terminating Anteon's contract for default. A default termination
could expose Anteon to liability for excess costs of reprocurement by the
government and have a material adverse effect on our ability to compete for
future contracts and task orders.

    DEPENDENCE ON KEY TECHNICAL PERSONNEL--IF WE LOSE OUR TECHNICAL PERSONNEL,
OUR BUSINESS MAY BE ADVERSELY AFFECTED.

    Our continued success depends in large part on our ability to recruit and
retain the technical personnel necessary to serve our clients effectively.
Competition for skilled personnel in the information technology and engineering
services industry is intense, and technology service companies often experience
high attrition among their skilled employees. Excessive attrition among our
technical personnel could increase our costs of performing our contractual
obligations, reduce our ability to efficiently satisfy our clients' needs and
constrain our future growth. In addition, we must often comply with provisions
in Federal government contracts that require employment of persons with
specified levels of education, work experience and security clearances. The loss
of any significant number of our existing key technical personnel or the
inability to attract and retain key employees in the future could have a
material adverse effect on our ability to win new business as well as our
financial condition, results of operations and debt service capability. Please
refer to the sections in this prospectus entitled "Business--Employees" and
"Management."

    ACQUISITION STRATEGY--WE INTEND TO PURSUE FUTURE ACQUISITIONS AND ARE
CURRENTLY CONSIDERING SPECIFIC ACQUISITIONS WHICH MAY ADVERSELY AFFECT OUR
BUSINESS IF WE CANNOT EFFECTIVELY INTEGRATE THESE NEW OPERATIONS.

    Our continued success will depend upon our ability to integrate Vector Data
Systems, Inc., Tech-matics, A&T and any businesses we may acquire in the future.
The integration of such businesses into our operations may require a
disproportionate amount of management's attention and our resources. There can
be no assurance that the acquired entities will operate profitably, that we will
realize anticipated synergies or that acquisitions will cause our operating
performance to improve.

                                       22
<PAGE>
    Although management regularly engages in discussions with and submits
acquisition proposals to acquisition targets, there can be no assurance that
suitable acquisition targets will be available in the future on reasonable
terms. In addition, to the extent that we complete any additional acquisitions,
no assurance can be given that acquisition financing will be available on
reasonable terms or at all, that any new businesses will generate revenues or
net income comparable to our existing businesses or that such businesses will be
integrated successfully or operated profitably. In addition, the new credit
facility contains certain covenants restricting, among other things,
acquisitions and capital expenditures, and the new credit facility and the
indenture limit the incurrence of additional indebtedness. Such covenants may
further limit our ability to complete additional acquisitions.

    POTENTIAL UNDISCLOSED LIABILITIES ASSOCIATED WITH ACQUISITIONS--WE MAY BE
SUBJECT TO CERTAIN LIABILITIES ASSUMED IN CONNECTION WITH OUR ACQUISITIONS THAT
COULD ADVERSELY AFFECT OUR BUSINESS.

    We conduct due diligence in connection with each of our acquisitions. In
connection with our acquisition of A&T, or any other acquisition made by us,
there may be liabilities that we fail to discover or that we inadequately assess
in our due diligence efforts. In particular, to the extent that prior owners of
any acquired businesses failed to comply with or otherwise violated procurement
requirements or applicable laws, Anteon, as the successor owner, may be
financially responsible for these violations or otherwise be adversely affected.
The discovery of any material liabilities could have a material adverse effect
on our financial condition, results of operations and debt service capability.

    RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS--OUR INTERNATIONAL BUSINESS
EXPOSES US TO ADDITIONAL RISKS INCLUDING EXCHANGE RATE FLUCTUATIONS, FOREIGN TAX
AND LEGAL REGULATIONS AND POLITICAL OR ECONOMIC INSTABILITY THAT COULD ADVERSELY
AFFECT OUR BUSINESS.

    In connection with our international operations, which generated less than
5% of our 1998 revenues, we are subject to risks associated with operating in
and selling to foreign countries, including:

    - devaluations and fluctuations in currency exchange rates;

    - changes in or interpretations of foreign regulations that may adversely
      affect our ability to sell all of our products or repatriate profits to
      the United States;

    - imposition of limitations on conversions of foreign currencies into
      dollars;

    - imposition of limitations on or increase of withholding and other taxes on
      remittances and other payments by foreign subsidiaries or joint ventures;

    - hyperinflation or political instability in foreign countries;

    - imposition or increase of investment and other restrictions or
      requirements by foreign governments; and

    - U.S. arms export control regulations and policies which govern our ability
      to supply foreign affiliates and customers.

To the extent we expand our international operations, these and other risks
associated with international operations are likely to increase. Although such
risks have not had a material adverse effect on our financial condition, results
of operations or debt service capability in the past, no assurance can be given
that such risks will not have such an adverse effect on us in the future.

    CONCENTRATION OF OWNERSHIP--WE WILL BE CONTROLLED BY ENTITIES UNDER THE
CONTROL OF MR. ISEMAN, WHOSE INTERESTS MAY NOT BE ALIGNED WITH YOURS.

    Affiliates of Caxton-Iseman Capital which are controlled by Mr. Frederick J.
Iseman beneficially own more than 99% of our capital stock. Consequently, Mr.
Iseman can control the election of our directors and the outcome of all matters
submitted to a vote of our shareholders, as well as our management, operations
and policies. Mr. Iseman's interests may not be fully aligned with yours and
this could lead to a strategy that is not in your best interests.

                                       23
<PAGE>
RISKS ASSOCIATED WITH "YEAR 2000" PROBLEM

    We are dependent on business systems, which include our information
technology systems and non-information technology devices with embedded
microprocessors in operating our business. We also depend on the proper
functioning of business systems of third parties, such as our vendors and
customers. The failure of any of these systems to appropriately interpret the
upcoming calendar year 2000 could have a material adverse effect on our
financial condition, results of operations, debt service capability, cash flow
and business prospects.

    During fiscal 1998 we implemented a plan which prepared our systems to be
Year 2000 compliant. We have completed our inventory phase and, based on this
analysis, we believe that our systems and applications will not be adversely
affected by any Year 2000 issues. Our aggregate costs incurred in 1998 to assess
our Year 2000 readiness were not material and management expects that any future
expenditures in 1999 will be similarly immaterial. However, we cannot assure you
that this estimate will be correct.

    In addition, we have addressed the Year 2000 issue with our significant
third-party suppliers and customers through inclusion of appropriate contractual
provisions in our business dealings with such companies to ensure their Year
2000 readiness. Management has no reason to believe that any such companies will
encounter Year 2000 issues. However, we cannot assure you that they will be
successful in avoiding any Year 2000 issues or resolving them in a timely
manner, or that any failure to do so would not materially and adversely affect
our business.

    Our inability to remedy our own Year 2000 problems or the failure of third
parties to do so may cause business interruptions or shutdown and result in
financial loss, regulatory actions, reputational harm and/or legal liability.

                                       24
<PAGE>
                                USE OF PROCEEDS

    We will not receive any cash proceeds from the issuance of the exchange
notes in exchange for the outstanding initial notes. We are making this exchange
solely to satisfy our obligations under our registration rights agreement. In
consideration for issuing the exchange notes, we will receive initial notes in
like aggregate accreted value equal to the accreted value of the exchange notes.

           UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL DATA

    The following unaudited pro forma condensed consolidated financial data is
based on the historical consolidated financial statements of Anteon, A&T and
Techmatics, adjusted to give effect to (1) the acquisition of Techmatics, (2)
the acquisition of A&T, (3) the offering of the initial notes, (4) the receipt
of the equity contribution, (5) the initial borrowings under the new credit
facility, (6) the repayment of all the amounts outstanding under the existing
credit facility and the repayment of all the outstanding indebtedness of A&T.

    The unaudited pro forma condensed consolidated statements of operations for
the year ended December 31, 1998 and the six months ended June 30, 1999 give
effect to the Transactions as if they were completed as of January 1, 1998 and
combine Anteon's and A&T's statements of income for the year ended December 31,
1998 and the six months ended June 30, 1999, and the results of operations of
Techmatics for the period from January 1, 1998 to May 29, 1998. The Techmatics
acquisition was effective as of May 29, 1998 and is reflected in the historical
balance sheet of Anteon as of June 30, 1999 and Anteon's historical statements
of income for the period from May 29, 1998 to December 31, 1998, and for the six
months ended June 30, 1999.

    The acquisition of A&T has been accounted for using the purchase method of
accounting. The purchase method of accounting allocates the aggregate purchase
price to the identifiable tangible and intangible assets acquired and
liabilities assumed based upon their respective estimated fair market values as
of the assumed date of combination. These estimates were based on preliminary
appraisals and other studies that will be completed during the remainder of
1999. The estimates of fair market value in the final allocation of the purchase
price may differ from those presented in the accompanying unaudited pro forma
condensed consolidated financial data.

    The unaudited pro forma condensed consolidated financial data does not
include certain cost savings related to the acquisition of A&T that we expect to
realize in connection with the acquisition or the costs of achieving such cost
savings. Such pro forma cost savings also do not reflect certain other cost
savings related to previous acquisitions or the costs of achieving such cost
savings. Management believes that additional cost savings will be generated
through reduced general and administrative expenses and the allocation of a
portion of Anteon's home office expenses to A&T. A significant portion of such
allocated home office expenses will be recovered through A&T's cost-plus
contracts which provide for reimbursement of a portion of A&T's indirect costs.
Management estimates that such cost savings will be approximately $3.7 million
annually before income taxes; however, there can be no assurance that such cost
savings will be achieved in the amounts expected or at all. These estimated
savings are not reflected in the pro forma data.

    The method of combining historical financial statements for the preparation
of the pro forma condensed consolidated financial data is for presentation only.
Actual statements of operations of Anteon will reflect the operating results of
both Anteon and A&T from the closing date of the acquisition with no retroactive
restatements. The unaudited pro forma condensed consolidated financial data is
provided for illustrative purposes only and does not purport to be indicative of
the financial condition or results of operations that would have been reported
had the Transactions occurred on the dates indicated, nor does it represent a
forecast of the consolidated financial position or results of operations for any
future period. The unaudited pro forma condensed consolidated financial data
should be read in conjunction with the historical financial statements, together
with the respective notes thereto, for Anteon, A&T and Techmatics, included
elsewhere in this prospectus.

    The following adjustments have been reflected in the Unaudited Pro Forma
Condensed Consolidated Statements of Operations:

(a) To reflect the historical results of operations of Techmatics for the period
    January 1, 1998 to May 29, 1998. The Techmatics acquisition was effective as
    of May 29, 1998 and is reflected in Anteon's historical statements of income
    for the periods from May 29, 1998 to December 31, 1998, and January 1, 1999
    to June 30, 1999.

(b) To reflect the historical results of operations of A&T.

(c) To reflect cost savings associated with the elimination of general and
    administrative expenses of A&T operating as a public company, including fees
    payable to the board of directors of A&T.

(d) To reflect incremental amortization of goodwill and non-compete agreements
    resulting from the Techmatics acquisition for the period January 1, 1998 to
    May 29, 1998.

(e) To reflect the amortization of goodwill of $83,490 from the acquisition of
    A&T, determined as follows:

    The acquisition was accounted for using the purchase method whereby the net
    tangible and identifiable intangible assets acquired and liabilities assumed
    were recognized at their estimated fair market values at the date of
    combination. These estimates were based on preliminary appraisals and other
    studies that will be completed during the remainder of 1999. Amortization
    expense on the goodwill from the acquisition is being amortized on a
    straight-line basis over 30 years.

(f) To reflect incremental interest expense associated with (1) the 12% Senior
    Subordinated Notes Due 2009, (2) initial borrowings under the new credit
    facility and (3) the amortization of deferred financing costs. Also reflects
    the elimination of interest expense associated with the existing credit
    facility. The components of pro forma interest expense for the year ended
    December 31, 1998 and the six months ended June 30, 1999 are as follows:

(g) To recognize Federal and state income taxes at a combined rate of 40%, after
    adjusting income (loss) before taxes for non-deductibility of goodwill
    amortization expense.

(h) The accompanying unaudited pro forma condensed consolidated statement of
    operations for the six months ended June 30, 1999 excludes $772 ($463, net
    of tax) of deferred financing costs associated with the existing credit
    facility, which were written off upon early repayment of all the amounts
    outstanding under such facility.

(i) EBITDA represents earnings before interest, taxes and depreciation and
    amortization. EBITDA also excludes infrequent and unusual charges of $0.1
    million for the year ended December 31, 1998 relating to asset write-offs at
    Techmatics, and $0.24 million for the six months ended June 30, 1999
    relating to a settlement with a former executive. Management believes that
    these charges will not recur and will not result in further cash charges.
    EBITDA is presented because we believe that it is a widely accepted
    supplemental indicator of an entity's ability to incur and service debt.
    However, EBITDA should not be considered by an investor as an alternative to
    net income or operating income as an indicator of our operating performance
    or cash flow from operations, or as an alternative to cash flows as a
    measure of liquidity.

SELECTED CONSOLIDATED FINANCIAL DATA OF ANTEON CORPORATION

    The following selected consolidated financial data has been derived from (1)
in the case of Anteon, its unaudited consolidated financial statements as of
June 30, 1999 and for the six months ended June 30, 1999 and 1998 and its
audited consolidated financial statements as of and for the years ended December
31, 1998 and 1997 and for the period from April 1, 1996 to December 31, 1996 and
(2) in the case of our Predecessor Company, its audited consolidated financial
statements for the period from January 1, 1996 to March 31, 1996, in each case
included elsewhere in this prospectus. The following selected consolidated
financial data as of December 31, 1996 of Anteon and as of and for the year
ended December 31, 1995 of our Predecessor Company is derived from audited
consolidated financial statements not included in this prospectus. Each of the
audited consolidated financial statements of Anteon and our Predecessor Company
have been audited by KPMG LLP, independent certified public accountants. The
following selected consolidated financial data as of and for the year ended
December 31, 1994 of our Predecessor Company is unaudited and has been prepared
on the same basis as the audited consolidated financial statements of our
Predecessor Company included elsewhere in this prospectus. In the opinion of
Anteon's management, the unaudited data reflects all adjustments, consisting of
normal recurring adjustments, necessary for a fair presentation of such data.
These results are not necessarily indicative of the results that may be expected
for a complete year or for any future period and are not comparable to the prior
period as a result of business acquisitions consummated in 1997, 1998 and 1999.
Results of operations of these acquired businesses are included in Anteon's
consolidated financial statements for the periods subsequent to the respective
dates of acquisition. You should read this data in conjunction with
"Capitalization," "Unaudited Pro Forma Condensed Consolidated Financial Data,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Anteon Corporation," "Business" and the historical consolidated
financial statements of Anteon, together with the respective notes thereto,

    EBITDA is presented because we believe that it is a widely accepted
    supplemental indicator of an entity's ability to incur and service debt.
    However, EBITDA should not be considered by an investor as an alternative to
    net income or operating income as an indicator of our operating performance
    or cash flow from operations, or as an alternative to cash flows as a
    measure of liquidity.

(i) For purposes of determining the ratio of earnings to fixed charges,
    "earnings" includes pre-tax income adjusted for fixed charges. "Fixed
    charges" consist of interest expense and that portion of operating lease
    rental expense representative of interest (deemed to be one-third of rental
    expense).

(j) Net debt represents total indebtedness less cash and investments in
    marketable securities.

                               ANTEON CORPORATION

    YOU SHOULD READ THE FOLLOWING INFORMATION TOGETHER WITH OUR CONSOLIDATED
FINANCIAL STATEMENTS AND THE RELATED NOTES INCLUDED ELSEWHERE IN THIS
PROSPECTUS. CERTAIN STATEMENTS IN THIS SECTION ARE "FORWARD-LOOKING STATEMENTS"
AND YOU SHOULD READ THE "FORWARD-LOOKING STATEMENTS" SECTION FOR SPECIAL
INFORMATION ABOUT OUR PRESENTATION OF FORWARD-LOOKING INFORMATION.

GENERAL

    Anteon is a leading provider of advanced information technology and
engineering services principally to a wide range of customers within the U.S.
Federal government. We serve hundreds of governmental clients through 39 offices
worldwide. We have performed work for all 14 Cabinet-level agencies, designing,
maintaining and upgrading critical elements of the government's information
technology infrastructure, such as emergency response, defense, intelligence,
logistics and financial management systems. The Federal government is among the
world's largest purchasers of information technology with expected total
expenditures in fiscal 1999 in excess of $30 billion.

    In April 1996 an investor group led by affiliates of Caxton-Iseman Capital
acquired Ogden Professional Services Corporation (the Predecessor Company),
which was renamed Anteon Corporation. Since that acquisition, we have
implemented a strategy designed to increase revenues through internal growth and
acquisitions, improve EBITDA profit margins to a level among the highest in our
industry and improve asset turnover. As a result of this strategy, from 1995 to
1998 we increased revenues at a compound annual growth rate of 32%. Improved
internal performance accounted for approximately 19% of this compound annual
growth rate with the remaining 13% increase attributable to our acquisitions of
Vector Data and Techmatics. In addition, EBITDA increased at a faster rate than
revenues and grew from $2.0 million in 1995 to $16.0 million in 1998 (or $18.8
million after giving effect to the full year of the Techmatics acquisition).
EBITDA margins increased from 1.9% to 6.4% during the same period (or 6.6% after
giving effect to the full year of the Techmatics acquisition). Cash flows used
in operations were $9.4 million for 1998.

    Substantially all of our services and products are provided under long-term
government contracts. Our contract base is well diversified and in 1998, we
performed work on approximately 3,000 task orders under more than 500 contracts
for approximately 400 customers. Management estimates that no task order
accounted for more than 5% of 1998 revenues. The contracts we perform can be
categorized into three primary types: time and materials ("time and materials"),
cost-plus fixed fee reimbursement ("cost-plus") and firm fixed price ("fixed
price"). Time and materials contracts represented approximately 47% of our 1998
revenues. Revenue recognition for time and materials contracts is recorded at
hourly rates, which are negotiated with the customer. Time and materials
contracts are typically more profitable because of our ability to negotiate
rates and manage costs on those contracts. Cost-plus contracts represented
approximately 34% of our 1998 revenues. Revenue is recognized under cost-plus
contracts on the basis of direct and indirect costs incurred plus a negotiated
profit calculated as a percentage of our costs. Cost-plus contracts provide
lower risk to us than other contract types because we are reimbursed for all
direct costs and certain indirect costs, such as overhead and general and
administrative charges, and are paid a fixed fee for work performed. Revenues
are recognized under fixed price contracts based on a percentage-of-completion
method. We may be exposed to cost overruns if we encounter variances from our
estimated costs under fixed price contracts. Accordingly, we attempt to minimize
the number of fixed price contracts, particularly for advanced software
development projects. Over the past three-year period fixed price contracts have
represented only 15% to 20% of our revenues, including 19% of 1998 revenues.

                                       36
<PAGE>
    Prices on Federal government contracts are generally set using estimated
costs plus a negotiated profit percentage. Under time and materials and fixed
price contracts, margins are not limited by law or regulation; however, the
Federal government's profit objectives in negotiating time and materials and
fixed price contracts seldom provide for operating profits in excess of 15%. Due
to competitive pressures, operating profits on time and materials and fixed
price contracts are often less than 10%. Under cost-plus contracts, operating
profits are statutorily limited to 15% of costs.

    In each year a significant portion of our revenues is derived from contract
backlog and a significant portion of that backlog represents work related to
maintenance, upgrade or replacement of systems under contracts or projects for
which we are the incumbent provider. Proper management of contracts is critical
to the overall financial success of Anteon and we believe that we manage costs
effectively. This allows us to be highly competitive on price. Our demonstrated
performance record and service excellence have enabled us to maintain our
position as an incumbent service provider on 100% of our major contracts that
have been recompeted over the past three years, while increasing our backlog
from $428 million in 1996 to $1.1 billion at June 30, 1999. These backlog
amounts consist of "funded" backlog, which is based upon amounts actually
appropriated by a customer for payment of goods and services and "unfunded"
backlog which is based upon management's estimates of the future potential of
our existing contracts to generate revenues for us.

    Anteon's costs may be categorized as direct costs such as labor and related
fringe costs which are directly attributable to contract performance, and
indirect costs such as corporate overhead which are not directly attributable to
contract performance. Under our time and materials and cost-plus contracts we
are allowed to charge our direct costs and an agreed-upon portion of our
indirect costs to the customer. A key element in the successful bidding and
execution of contracts is the control of indirect costs. We have developed
comprehensive management information and resource management systems in order to
increase the productivity of our finance and administrative support areas. As a
result of these efforts, our indirect costs have grown at rates much lower than
overall revenues. We believe our indirect costs, at approximately 15% of sales,
are among the lowest in the industry.

    On March 7, 1999 we entered into a definitive agreement to acquire all the
outstanding shares of common stock of A&T. We consummated the acquisition on
June 23, 1999 after the approval of the acquisition by the shareholders of A&T.
The acquisition significantly increased the size of Anteon. Pro forma for the
acquisition, Anteon's net sales and EBITDA in 1998 would have been $450.8
million and $31.4 million, respectively. Following the consummation of the
acquisition, in addition to the cost savings reflected in the Unaudited Pro
Forma Condensed Consolidated Financial Data appearing elsewhere in this
prospectus, we believe that Anteon will be able to realize costs savings through
synergies in indirect costs and general and administrative expenses. In
addition, after giving pro forma effect to the acquisition, the level of
billable indirect costs under our contracts will increase because the proportion
of our revenues generated by cost-plus contracts will increase from 40% to 55%.
This will allow Anteon to receive payment for a greater portion of its indirect
costs. Based on our ability to pass such indirect costs through to our
government customers, we estimate this will result in an additional $2.5 million
of reimbursable costs.

SIX MONTHS ENDED JUNE 30, 1999 COMPARED WITH SIX MONTHS ENDED JUNE 30, 1998

    REVENUES

    Revenue increased 34.8% to $145.6 million in for the first six months in
1999 from $108.0 million in 1998. The revenue growth reflects the acquisition of
Techmatics as well as continued internal growth from the Company's information
technology and engineering technology businesses. Techmatics generated $43.9
million in revenue during the six months ended June 1999 as compared with one
month's revenue of $8.2 million in June 1998. The company was also able to
significantly increase its contract backlog with several major awards in late
1998 and early 1999 including Answer, ITOP II and Theater Ballistic Missile
Defense and began to earn revenue on the startup of those new contracts. Backlog
increased from $414 million as of June 30, 1998 to $1.3 billion as of June 30,
1999.

    COSTS OF REVENUES

    Costs of revenues, as a percent of revenues, decreased to 88.3% during the
first six months in 1999 from 89.1% increasing the gross profit, which grew by
8%, from 10.9% in 1998 to 11.7% in 1999. This favorable result is attributable
to several factors. Contributing to the growth was the relatively higher
operating profit margin of Techmatics and the improved profitability of the
Company's Products and Services business unit.

    GENERAL AND ADMINISTRATIVE EXPENSES

    General and administrative expenses, which consists of corporate management,
finance and administration, marketing and contracts, was 5.6% of revenues for
the first six months of 1999. This was a 4% increase from the same period in
1998. The growth can be attributed primarily to an investment in infrastructure
to support a substantially larger company. In addition, the Company spent more
on marketing costs to pursue opportunities created from new contract awards
which substantially increased backlog.

                                       38
<PAGE>
    OPERATING INCOME

    Operating income continued to grow increasing by 33.3% to $6.8 million in
fiscal 1999 from $5.1 million in fiscal 1998. The operating profit growth was
attributable to the addition of Techmatics. Operating margins remained steady at
4.7% of revenue.

    Net interest expense increased 224% to $5.5 million in the first six months
of 1999 from $1.7 million in the same period in 1998. This was principally due
to the cost of debt incurred to acquire Techmatics and accrued interest expenses
for the new senior subordinated notes. This included fees associated with a
bridge loan facility.

    Earnings before taxes decreased 67% to $1.1 million in the first six months
of 1999 from $3.4 million in the same period in 1998. This decline was primarily
attributable to interest expense on the notes.

1998 COMPARED WITH 1997

    REVENUES

    Revenues increased by $73.5 million or 41.7% to $249.8 million in 1998 from
$176.3 million in 1997 due to internal growth and acquisitions. Anteon's
internal growth (I.E., excluding acquisitions) of 13.5%, or $23.9 million, was
primarily driven by increased licensing revenues from the Product Applications
and Services Group of the Enterprise Solutions and Services Group and increased
revenues under the TC-AIMS contract. Techmatics generated $49.6 million in
revenues subsequent to its acquisition on May 29, 1998. The full year impact
from the acquisition of Techmatics increased Anteon's pro forma revenues to
$282.5 million. Anteon also significantly increased its contract backlog by
winning several major awards in late 1998, including the $25 billion GSA ANSWER
contract and the $10 billion Department of Transportation ITOP II contract.
Backlog increased during 1998 from $341 million at January 1, 1998 to $1.2
billion at December 31, 1998, $119.2 million of which was attributable to new
contract awards and $230 million of which was attributable to the acquisition of
Techmatics and the remainder of which was attributable to our ability to
maintain our position as an incumbent service provider on 100% of our major
contracts that have been recompeted.

    COSTS OF REVENUES

    Costs of revenues increased by $62.1 million or 38.9% to $221.6 million in
1998 from $159.5 million in 1997. As a percentage of revenues, costs of revenues
decreased to 88.7% in 1998 from 90.5% in 1997. The improvement in gross margins
was attributable to improved reimbursement for indirect overhead expenses,
higher gross profit margins of Techmatics and improved profitability of Anteon's
Product Applications and Services Group.

    GENERAL AND ADMINISTRATIVE EXPENSES

    General and administrative expenses increased by $7.2 million or 88.9% from
$15.3 million in 1998 from $8.1 million in 1997. As a percentage of revenues,
general and administrative expenses increased to 6.1% in 1998 from 4.6% in 1997.
General and administrative expenses consist of corporate management, finance and
administration, marketing and contract functions. The increase in general and
administrative expense was attributable primarily to the addition of $3.1
million of overhead expenses of Techmatics in 1998 and the expansion of Anteon's
personnel and management to meet the increasing demands of its expanding
business. Generally, a significant portion of these costs are reimbursable under
Anteon's contracts. Additionally, general and administrative expenses were
increased by a $0.7 million write-off of unamortized contract start-up costs
incurred by our Predecessor Company relating to contracts that were awarded in
1995.

    OPERATING INCOME

    Operating income increased by $5.3 million or 103.9% to $10.4 million in
1998 from $5.1 million in 1997. As a percentage of revenues, operating income
improved by 45% to 4.2% in 1998 from 2.9% in 1997.

    Net interest expense increased to $5.6 million in 1998 from $2.4 million in
1997 principally due to increased debt incurred to acquire Techmatics.

    Income before taxes increased 78% to $4.8 million in 1998 from $2.7 million
in 1997. Anteon's effective tax rate increased to 48.8% in 1998 from 39.3% in
1997 principally due to the non-deductibility of goodwill generated by Anteon's
acquisition of Vector Data.  After-tax income increased 56.3% to $2.5 million in
1998 from $1.6 million in 1997. The large increase in revenue and operating
earnings, offset in part by the increase in interest expense and tax rate,
contributed to this increase in net income.

1997 COMPARED WITH 1996

    REVENUES

    Revenues increased by $34.5 million or 24.3% to $176.3 million in 1997 from
$141.8 million in 1996. Internal growth (I.E., excluding acquisitions) of 20.4%
or $28.9 million was driven by increased revenues under the CAPZONE and PACZONE
contracts. Vector Data generated $5.6 million in revenues subsequent to its
acquisition in August 1997.

    COSTS OF REVENUES

    Costs of revenues increased by $29.9 million or 23.1% to $159.5 million in
1997 from $129.6 million in 1996. As a percentage of revenues, costs of revenues
decreased to 90.5% in 1997 from 91.4% in 1996. Fiscal 1997 represented the first
full fiscal year in which current management operated Anteon. The increase in
gross margins was attributable to improved performance on several fixed price
contracts.

    GENERAL AND ADMINISTRATIVE EXPENSES

    General and adminstrative expenses increased by $1.4 million or 20.9% to
$8.1 million in 1997 from $6.7 million in 1996. As a percentage of revenues,
general and administrative expenses decreased to 4.6% in 1997 from 4.7% in 1996.
The aggregate dollar increase was attributable to the addition of Vector Data's
general and administrative charges and the expansion of Anteon's marketing staff
in an effort to increase backlog.

    OPERATING INCOME

    Operating income increased by $1.7 million or 50.0% to $5.1 million in 1997
from $3.4 million in 1996. Operating margins grew by 21% to 2.9% in 1997 from
2.4% in 1996. This improved operating income was primarily due to certain
profitable contracts and improved profits generated by Vector Data.

    Interest expense increased to $2.4 million in 1997 from $1.5 million in
1996, principally reflecting a full year of debt outstanding in 1997 compared to
eight months the prior year (reflecting the date of the original acquisition of
the Predecessor Company) as well as increased indebtedness due to the
acquisition of Vector Data.

    Income before taxes increased 35.0% to $2.7 million in 1997 from $2.0
million in 1996 as a result of a higher operating profit margin, offset by
increased interest expense. Anteon's effective tax rate increased to 39.3% in
1997 from 36.3% in 1996, principally due to the non-deductibility of goodwill
generated from Anteon's acquisition of Vector Data. After-tax income increased
23.1% to $1.6 million in 1997 from $1.3 million in 1996.

LIQUIDITY AND CAPITAL RESOURCES

SIX MONTHS ENDED JUNE 30, 1999 CASH FLOW

    For the first six months of 1999, net cash provided from operating
activities totaled $9.6 million. The positive cash flow resulted primarily from
a $1.9 million decrease in accounts receivable and a $5.8 increase in accounts
payable/accrued expenses. The decrease in accounts receivable was driven in
large part by the successful collection efforts of invoices that had been
backed-up in processing by the Federal government in a number of its payment
offices. The overall days sales outstanding ("DSO") for the Company at mid-year
ended June 30, 1999 was 76 days. While the Company's core business maintained a
DSO in the 55-70 day range during 1998, its acquired subsidiaries, Techmatics
and Vector Data, have maintained DSO's of over 100 days during the past year.
Processes are being put in place to reduce the DSO to the 60-day range during
the second half of 1999.

    Net cash used in investing activities for the six months totaled $118.7
million. The principal investment was the purchase of Analysis & Technology for
approximately $115.4 million, including transaction costs, which closed on June
23. Capital expenditures totaled $1.3 million for the six months.

    Net cash provided by financing activities for the six months totaled $111.7
million. This was primarily due to $100 million in funds obtained through
issuance of the new senior subordinated notes, an equity contribution of $22.5
million, net of a $4.9 million in paydown of deferred obligations associated
with the 1998 acquisition of Techmatics, and $8.5 million of fees incurred in
connection with the new senior subordinated notes and the new credit facility.

1998 CASH FLOW

    Net cash used in operating activities for 1998 totaled $8.3 million. The net
cash requirements resulted primarily from a $15.6 million increase in accounts
receivable. This increase was principally due to a delay in processing of
contractor payments by the Federal government in a number of its payment offices
due to a reduction of administrative personnel and difficulties in successfully
implementing office automation to relieve the congestion. The Federal government
is working to correct this problem and we believe these delays should be
resolved by the end of 1999. We focus on capital management in order to maximize
asset turnover and reduce working capital. At the time its Predecessor Company
was acquired, Anteon had days sales oustanding ("DSO") of 119 days. Anteon was
able to reduce overall DSO for the years ended December 31, 1996, 1997 and 1998
to 79 days, 59 days and 89 days, respectively. Anteon's DSO increased in 1998
due to the acquisition of Vector Data in late 1997 and Techmatics in May 1998.
Prior to the acquisitions of Vector Data and Techmatics, Anteon maintained a
63-day average DSO in 1998. Vector Data and Techmatics each had DSOs of over 100
days during 1998. Anteon has implemented initiatives to reduce Anteon's overall
DSO to the 70-day range by the end of June 1999.

    Net cash used in investing activities for 1998 totaled $37.5 million. The
principal investment requirement was $29.7 million for the acquisition of
Techmatics. Capital expenditures totaled $2.1 million, approximately 40% of
which were attributable to Anteon's capital expenditure for CostPoint, an
integrated enterprise-wide information system.

    Net cash provided by financing activities for 1998 totaled $45.3 million.
This included an increase of $46.3 million in senior debt borrowing to $70.4
million at December 31, 1998 from $24.1 million at December 31, 1997.

1997 CASH FLOW

    Net cash flow from operating activities in 1997 totaled $14.1 million,
principally reflecting a $10.1 million reduction in accounts receivable, $5.1
million in depreciation and amortization and $1.6 million in net income.

                                       41
<PAGE>
    Net cash used in investing activities totaled $18.1 million in 1997. The net
cash cost of acquiring Vector Data was $17.2 million. Additionally, Anteon had
$0.8 million capital expenditures.

    Net cash provided from financing activities totaled $4.5 million, reflecting
an increase in Anteon's senior debt from $19.6 million at December 31, 1996 to
$24.1 million at December 31, 1997.

LIQUIDITY


    In June 1999, the Company entered into a new five-year line of credit with
nine major banks totaling $180 million. This line of credit is comprised of a
$120 million revolving credit facility subject to availability based on a
borrowing base and a $60 million term note. The borrowing base is determined by
computing a percentage of Anteon's billed and billable accounts receivable, with
availability totaling $54.9 million as of June 30, 1999. Aggregate loans drawn
under this revolving line of credit totaled $13.0 million as of June 30, 1999.
In addition, Anteon secured advances of $60.0 million against the term note.
June 1999 ending cash balance totaled $2.9 million. However, access to the bank
line is further restricted by the leverage covenant which is 5.75 times the
adjusted, pro forma EBITDA (as defined in the new credit facility) over the past
12 months. Based on the June 30th leverage of just under 5.00, this left
approximately $27 million in immediately available liquidity. The Company plans
a further improvement in its accounts receivable DSO over the next 6-9 months
timeframe, freeing up approximately $12-15 million in cash. This DSO reduction
and liquidity improvement would be used to reduce the Company's overall
leverage.


    We intend to meet future capital commitments, which principally involve the
execution of additional acquisitions, through additional senior bank debt and
the issuance of subordinated debt and equity in the public and private capital
markets.

YEAR 2000

    During fiscal 1998 we implemented a plan which prepared our systems to be
Year 2000 compliant. We have completed our inventory phase and, based on this
analysis, we believe that our systems and applications will not be adversely
affected by any Year 2000 issues. Our aggregate costs incurred in 1998 to assess
our Year 2000 readiness were not material and management expects that any future
expenditures in 1999 will be similarly immaterial. However, we cannot assure you
that this estimate will be correct.

    In addition, we have addressed the Year 2000 issue with our significant
third-party suppliers and customers through inclusion of appropriate contractual
provisions in our business dealings with such companies to ensure their Year
2000 readiness. Management has no reason to believe that any such companies will
encounter Year 2000 issues. However, we cannot assure you that they will be
successful in avoiding any Year 2000 issues or resolving them in a timely
manner, or that any failure to do so would not materially and adversely affect
our business.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                     CONDITION AND RESULTS OF OPERATIONS--
                          ANALYSIS & TECHNOLOGY, INC.

    YOU SHOULD READ THE FOLLOWING INFORMATION TOGETHER WITH A&T'S CONSOLIDATED
FINANCIAL STATEMENTS AND THE RELATED NOTES INCLUDED ELSEWHERE IN THIS
PROSPECTUS. CERTAIN STATEMENTS IN THIS SECTION ARE "FORWARD-LOOKING STATEMENTS"
AND YOU SHOULD READ THE "FORWARD-LOOKING STATEMENTS" SECTION FOR SPECIAL
INFORMATION ABOUT OUR PRESENTATION OF FORWARD-LOOKING INFORMATION.

RESULTS OF OPERATIONS

FISCAL 1999 COMPARED WITH FISCAL 1998

    The major factors in the comparison of fiscal 1999 with fiscal 1998 are as
follows:

    - Revenue increased 6.5% to $170.4 million from $160.0 million.

    - Revenue for the Company's Engineering and Information Technologies
      ("Engineering/IT") business grew 3.2%

    - Interactive Media's revenue increased 29.7%, including a 16.4% increase in
      commercial revenue.

    - Operating margin increased to 6.0% from 5.0%.

     --  Operating margin was 6.1% for Engineering/IT and 5.6% for Interactive
         Media.

     --  Margins improved due to improved cost controls. Also contributing to
         the margin improvement in Interactive Media was a decrease of fixed
         indirect expenses as a percentage of revenue due to revenue growth.

     --  Operating margin was 5.3% for fiscal 1998 without the effect of a
         non-recurring software charge.

    - Net earnings were $4.9 million compared with $4.2 million resulting in an
      increase of 16.2%. During fiscal 1998, the Company sold its share of a
      joint venture, Automation Software Incorporated (ASI), and took the
      software charge previously noted. The joint venture sale increased the
      Company's effective tax rate. The net effect of these non-recurring items
      and their tax effects was an after-tax gain of $87 thousand.

    - Basic earnings per share increased 12.6% to $1.34 from $1.19. On a diluted
      basis, earnings per share increased 12.1% to $1.20 from $1.07.

    Revenue increased 6.5% to $170.4 million in fiscal 1999 from $160.0 million
in fiscal 1998. The revenue increase is attributable to continued growth in both
the Company's Engineering/IT business and its Interactive Media technology-based
training business. For fiscal 1999, the Company's Engineering/IT revenue grew
3.2% to $144.2 million from $140.0 million in fiscal 1998. Interactive Media's
revenue increased 29.7% to $26.1 million from $20.1 million in fiscal 1998. Its
commercial revenue increased 16.4% to $17.1 million from $14.7 million in fiscal
1998.

    Revenue for the Company's Engineering/IT business was adversely affected by
a decrease in work subcontracted to other companies and a decrease in purchased
materials. For fiscal 1999, work subcontracted to other companies and purchased
materials decreased $5.3 million and $1.9 million, respectively, from fiscal
1998. Subcontracting was down because in some cases A&T is gaining market share,
some subcontractors have gotten their own contracts, and some subcontractor's
work has not been renewed by the customer. Purchases of materials are down due,
in part, to a U.S. Navy mine clearing hardware

                                       43
<PAGE>
contract that is nearing completion. Without the effect of subcontracts and
materials, Engineering/IT revenue would have been up 10.2% for fiscal 1999.

    Interactive Media's revenue was favorably affected by the acquisition of UP,
Inc. in November of last year and by an expanded sales force.

    During the year, total backlog varied between $589.4 million and $805.7
million. In fiscal 1999, $56.1 million of backlog expired without being funded,
while in fiscal 1998, $50.7 million of backlog expired without being funded. The
backlog used during fiscal 1999, plus the unfunded backlog that expired, was
more than offset by newly awarded contracts. Backlog as of March 31, 1999 was
$775.8 million, a 31.6% increase from $589.4 million at the end of fiscal 1998.
Government funding continues to be dependent on congressional approval of
program level funding and on contracting agency approval for the Company's work.
The extent to which backlog will be funded in the future cannot be determined.

    Operating earnings increased 29.4% to $10.3 million from $7.9 million in
fiscal 1998. Operating margins from continuing operations were 6.0% in fiscal
1999 compared with 5.0% in fiscal 1998. Fiscal 1998 operating earnings were
negatively affected by software charges totaling $530 thousand, recorded in the
second quarter of fiscal 1998, primarily for capitalized software development
costs to support customers in the natural gas business and software development
and related costs for image processing products which the Company deemed to be
unrecoverable. Without these charges, the operating margin for fiscal 1998 was
5.3%.

    Operating margin for Engineering/IT, increased from 5.3% in fiscal 1998,
without the software charges, to 6.1% in fiscal 1999. The reduction in lower
margin subcontract and material revenue plus improved cost controls and good
performance on contracts contributed to the Engineering/IT increase. Operating
margins for Interactive Media increased from 5.4% in fiscal 1998 to 5.6% in
fiscal 1999. The increase was due to a decrease in indirect expenses as a
percentage of revenue due to the revenue growth.

    Total other expenses as a percentage of revenue were 0.9% for fiscal 1999
compared to 0.7% in fiscal 1998, excluding the effect of the sale of the
Company's Interest in ASI to the Company's joint venture partner. The sale
resulted in a pre-tax gain of $1.6 million in fiscal 1998. For fiscal 1999, both
interest expense and amortization of goodwill increased due to the Company's
recent acquisitions, including a contingent payment to the former owner of UP,
Inc. as discussed more fully in "Liquidity and Capital Resources."

    Earnings before income taxes increased 4.9% to $8.8 million from $8.3
million in fiscal 1998. The Company's effective tax rate on earnings before
income taxes was 44.3% in fiscal 1999 compared with 49.8% in fiscal 1998. The
effective tax rate was higher in fiscal 1998, primarily due to the recognition
of deferred taxes on undistributed earnings of the Company's joint venture, as a
result of the sale. The effective tax rate without the effect of the joint
venture sale was 43.9%. The effective tax rate in fiscal 1999, compared to the
effective tax rate without the effect of the joint venture sale is fiscal 1998,
was higher due to an increase in nondeductible amortization of goodwill
associated with the UP acquisition.

    Net earnings increased 16.2% to $4.9 million from $4.2 million in fiscal
1998. The revenue increase and the operating margin increase both contributed to
the net earnings increase. The net effect of the sale of the Company's interest
in its joint venture and the software charges noted above was an after-tax gain
of $87 thousand for fiscal 1998.

    Basic earnings per common share increased 12.6% to $1.34 from $1.19 in
fiscal 1998. Diluted earnings per common share increased 12.1% to $1.20 from
$1.07 in fiscal 1998.

    The weighed average number of common shares used to compute basic earnings
per share increased to 3.6 million in fiscal 1999 from 3.5 million in fiscal
1998. The weighted average number of common shares used to compute diluted
earnings per share increased to 4.0 million in fiscal 1999 from 3.9 million in
fiscal 1998. The increase was due primarily to an increase in the number of
stock options outstanding and a

                                       44
<PAGE>
higher average stock price, offset in part by the repurchase of the Company's
shares as discussed more fully below in "Liquidity and Capital Resources".

FISCAL 1998 COMPARED WITH FISCAL 1997

    Revenues increased 12.2% to $160.0 million in fiscal 1998 from $142.5
million in fiscal 1997. The revenue increase is attributable to continued growth
in both A&T's Engineering/IT business and in its Interactive Media
technology-based training business. In fiscal 1998, A&T's Engineering/IT
revenues grew 11.5% to $140.0 million from $125.4 million in fiscal 1997. IMC's
revenues increased 17.3% to $20.1 million. Its commercial revenues increased
58.7% to $14.7 million in fiscal 1998 from $9.3 million in fiscal 1997 and its
government related revenues decreased 30% to $5.4 million in fiscal 1998 from
$7.9 million in fiscal 1997.

    A&T made five acquisitions during fiscal year 1998. In total, these
acquisitions added approximately $6.6 million to A&T's fiscal 1998 revenues.

    During the year, total backlog varied between $461.7 million and $589.4
million. In fiscal 1998, $50.7 million of backlog expired without being funded,
while in fiscal 1997, $19.5 million of backlog expired without being funded. The
backlog used during fiscal 1998, plus the unfunded backlog that expired, was
more than offset by newly awarded contracts and backlog added as a result of
A&T's acquisitions. Backlog as of March 31, 1998 was $589.4 million, a 22.6%
increase from $480.7 million as of March 31, 1997, and was well above A&T's
benchmark of two and one-half times current revenues. Government funding
continues to be dependent on congressional approval of program level funding and
on contracting agency approval for A&T's work. The extent to which backlog will
be funded in the future cannot be determined.

    Operating earnings increased 17.4% to $7.9 million in fiscal 1998 from $6.8
million in fiscal 1997. Operating margins were 5.0% in fiscal 1998 compared with
4.7% in fiscal 1997. Fiscal 1998 operating earnings were negatively affected by
software charges totaling $530,000, recorded in the second quarter of fiscal
1998, primarily for capitalized software development costs to support customers
in the natural gas business and software development and related costs for image
processing products which A&T deemed to be unrecoverable. Without these charges,
the operating margin for fiscal 1998 was 5.3%.

    Operating margins for Engineering/IT, without the software charges,
increased from 5.0% in fiscal 1997 to 5.3% in fiscal 1998. Operating margins for
IMC during these same periods increased from 3.2% to 5.4%. Margins improved
overall because of improved cost controls. Also contributing to margin
improvement in IMC was a decrease of fixed indirect expenses as a percentage of
revenues due to revenue growth.

    Total other expenses were affected by the sale of A&T's interest in
Automation Software Incorporated ("ASI") to A&T's joint venture partner. The
sale resulted in a pre-tax gain of $1.6 million in fiscal 1998. In addition, the
proceeds from the sale were used to pay down certain of A&T's long-term debt,
resulting in decreased interest expense in fiscal 1998. Other net expense
increased in fiscal 1998 to 0.6% of revenue compared with 0.5% of revenues in
fiscal 1997. The other net expense increase was due, in part, to the
amortization of goodwill associated with A&T's fiscal 1998 acquisitions.

    Earnings before income taxes increased 43.5% to $8.3 million in fiscal 1998
from $5.8 million in fiscal 1997. A&T's effective tax rate on earnings before
income taxes was 49.8% in fiscal 1998 compared with 41.9% in fiscal 1997. The
effective tax rate was higher in fiscal 1998, primarily due to the recognition
of deferred taxes on undistributed earnings of A&T's joint venture as a result
of the sale, and due to an increase in nondeductible amortization of goodwill
associated with A&T's acquisitions. The effective tax rate without the effect of
the joint venture sale was 43.9%.

    Net earnings increased 24.2% to $4.2 million from $3.4 million in fiscal
1997. The revenue increase and the operating margin increase both contributed to
the increase in net earnings. The net effect of the sale of A&T's interest in
its joint venture and the software charges noted above and the related tax
effects was an after-tax gain of $0.1 million in fiscal 1998.

LIQUIDITY AND CAPITAL RESOURCES

FISCAL 1999 CASH FLOW

    For fiscal 1999, net cash provided by operating activities totaled $5.9
million. The net cash increase resulted primarily from net earnings before
deducting non-cash charges for depreciation of property and amortization of
intangible assets, and a decrease in accounts payable and accrued expenses of
$1.3 million, offset in part and an increase in contract, notes, and other
receivables of $3.3 million. Contract receivables totaled $28.7 million, $25.6
million and $247.7 million as of March 31, 1999, 1998, and 1997, respectively,
and represented approximately 41%, 40%, and 43% of total assets as of those
dates. The average period of payment to the Company was 57 days at March 31,
1999, 54 days at March 31, 1998; and 58 days at March 31, 1997.

    Net cash used in investing activities for fiscal 1999 totaled $5.6 million.
The primary use of this cash was for the addition of office equipment, the
development of a new management information system, and for acquisitions,
including a contingent payment to the former owners of UP, Inc., in accordance
with the purchase agreement for the acquisition executed in November 1997.

    Net cash used in financing activities for fiscal 1999 totaled $1.2 million.
The primary source of cash from financing activities was from the exercise of
stock options. The primary uses of cash from financing activities were for the
payment of dividends and the repurchase of the Company's common shares. On May
30, 1997, the Company announced it had expanded its share repurchase program.
The Company's Board of Directors authorized the repurchase of an additional
450,000 shares or a total of up to 750,000 shares in amounts and at times and
prices to be determined by the Company's management. Since the program was
initiated in March 1996, the Company has repurchased 399,400 shares. Since March
31, 1998 the company has repurchased 42,900 shares under this repurchase program
at current market prices on the dates of purchase. There are approximately 3.7
million shares outstanding at March 31, 1999.

    Any capital needs not satisfied by cash generated from operations, were, and
in the future will be, met with money borrowed by the Company under its
revolving credit agreement. The total funds available to the Company under its
revolving credit agreement at March 31, 1999 were $20.0 million. There was no
borrowing under the Company's agreement as of March 31, 1999 or 1998.

    It is anticipated that the Company's existing cash, together with funds
generated from operations and available borrowings under its revolving credit
agreements, will be sufficient to meet its normal working capital requirements
for the foreseeable future. As of March 31, 1999, the Company does not have any
major capital commitments.

    The Company believes that inflation has not had a material effect on its
business.

FISCAL 1998 CASH FLOW

    For fiscal 1998, net cash provided by operating activities totaled $7.8
million. The net cash increase resulted primarily from earnings before deducting
non-cash charges for depreciation of property and amortization of intangible
assets, and a decrease in contract, notes and other receivables of $1.1 million.
The decrease in contract receivables was due primarily to faster payment by the
government as a result of electronic processing of selected government invoices
and to collection of receivables under firm fixed-price contracts. Contract
receivables totaled $25.6 million, $24.7 million and $24.2 million as of March
31, 1998, 1997, and 1996, respectively, and represented approximately 40%, 43%
and 43% of total assets as of those dates, respectively. The average period of
payment to A&T was 54 days at March 31, 1998, 58 days at March 31, 1997 and 71
days at March 31, 1996.

    Net cash used in investing activities for fiscal 1998 totaled $9.1 million.
Cash provided from the sale of ASI of $3.0 million was more than offset by
facility expenditures and by expenditures for A&T's fiscal 1998

                                       46
<PAGE>
acquisitions. Payments for the acquisitions were made from existing cash and
funds available under A&T's revolving credit agreement.

    Net cash used in financing activities for fiscal 1998 totaled $670,000. The
primary source of cash from financing activities was from the exercise of stock
options. The primary uses of cash from financing activities were for the payment
of dividends and the repurchase of shares of A&T's common stock.

YEAR 2000

    A&T established a task force in January 1998 to assess Year 2000 risks,
identify and implement solutions to known problems and report the results of the
assessment. The task force examined the services and products A&T provides, its
internal information technology software, facilities and infrastructure and
third-party risks. A&T is approaching its Year 2000 readiness program in three
phases: assessment, planning and preparation, and implementation.

    While A&T has plans in place to address known Year 2000 issues under its
control, an infrastructure problem outside of its control could disrupt A&T's
operations depending on the nature and severity of the problems. A&T expects
that most utilities and service providers would be able to restore service
interruptions caused by Year 2000 problems within days. However, more pervasive
system problems involving multiple providers could last longer depending on the
complexity of the systems and the effectiveness of their contingency plans.

    Although A&T is dedicating reasonable resources towards attaining Year 2000
readiness, there is no assurance it will be successful in its efforts to
identify and address all Year 2000 issues. Even if A&T acts in a timely manner
to complete all of its assessments and identifies, develops and implements
remediation plans it believes to be adequate, some problems may not be
identified or corrected in time to prevent material adverse consequences to A&T.
Our statements above regarding estimated completion dates, costs, risks and
other forward-looking statements regarding Year 2000 are based on A&T's best
estimates given information that is currently available and is subject to
change. As A&T continues to progress with its Year 2000 initiatives, it may
discover that actual results will differ materially from these estimates.

    A more detailed explanation of the "Year 2000 Readiness Disclosure" for A&T
is available in A&T's Annual Report on Form 10-K for the fiscal year ended March
31, 1998. Please refer to the section entitled "Where You Can Find More
Information" which appears later in this prospectus for more information.

        THE FEDERAL GOVERNMENT INFORMATION TECHNOLOGY SERVICES INDUSTRY

OVERVIEW

    The U.S. Federal government is among the world's largest purchasers of
information technology. The Office of Management and Budget ("OMB") projects
that total information technology expenditures in fiscal 1999 will exceed $30
billion. These expenditures have grown consistently during the 1990s. According
to the OMB, from 1991 to 1998 the Federal government information technology
market increased at a consolidated annual growth rate of 4.2%. As shown below,
the annual Federal information technology budget for fiscal year 1998 through
fiscal year 2002 is expected to grow at a rate of approximately 4.4% annually.
Civilian agency information technology budgets are expected to be 60% to 65% of
the total Federal information technology budget, or between $18 billion and $20
billion annually, and annual defense information technology budgets are expected
to be 35% to 40% of such total budget, or between $11 and $12 billion annually.
However, due to projected increased Federal government outsourcing, the amount
of information technology services procured from contractors is expected to
increase at a faster rate, by approximately 6.9% per annum from 1998 to 2002.
The following table sets forth the Federal government's historical and projected
expenditures for information technology from 1991 to 2002:

TRENDS

    There are five primary factors that should drive this growth of the Federal
information technology services market: (1) increased outsourcing, (2) emphasis
on systems modernization, (3) legislative efforts to streamline government
procurement procedures, (4) the increasing requirement for integration of
commercial and custom information technology applications and (5) increased
emphasis on training and simulation.

    - INCREASED OUTSOURCING. Major forces contributing to the increase in
      information technology outsourcing are Federal government downsizing,
      increased procurement efficiency, the declining availability of
      programming skills among Federal government personnel (and government
      staffing limits) and the backlog of software maintenance tasks at most
      government data centers. The GSA anticipates a continuation of the trend
      toward the use of outside information technology providers. According to
      the OMB, 78% of the Federal government's information technology spending
      in 1998, or $23.1 billion, flowed through to contractors. According to
      OMB, outsourced information technology services are projected to grow at a
      rate faster than overall Federal government expenditures on information
      technology, increasing to 86% of projected expenditures in 2002 or $30.2
      billion and resulting in a 6.9% growth rate per annum.

    - EMPHASIS ON SYSTEM MODERNIZATION. As part of their efforts to reduce
      procurement costs, the Department of Defense and the U.S. Navy, in
      particular, are emphasizing upgrading existing platforms to next
      generation technologies rather than procuring completely new systems. For
      example, the Department of Defense's funding priorities in 1999 emphasize
      the modernization and upgrading of shipboard systems to maintain the U.S.
      Navy's superior fighting capabilities. Rather

                                       48
<PAGE>
      than replace its aging fleet of ships, the U.S. Navy has decided to invest
      in upgrading its existing fleet with the latest computer and weapons
      systems. To accomplish this in an environment of reduced Armed Forces
      personnel, the U.S. Navy is increasingly dependent on highly skilled
      technical specialists to provide a full spectrum of services to support
      these activities. After giving effect to the acquisition, we will be
      deeply involved in virtually every major U.S. Navy platform as well as
      with many of the strategic Program Executive Offices. Moreover, A&T is
      among the top-tier U.S. Navy Warfare Center contractors and is the leading
      contractor based on 1998 revenues for the Naval Undersea Warfare Center
      ("NUWC"). With a broad-based presence on critical U.S. Navy programs,
      management believes that Anteon and A&T are well-positioned to benefit
      from the billions of dollars in modernization and upgrade expenditures
      anticipated by the U.S. Navy over the next decade.

    - INFORMATION TECHNOLOGY MANAGEMENT REFORM ACT OF 1996 ("ITMRA"). The ITMRA,
      through acquisition vehicles such as GSA Schedules and IDIQ contracts, has
      changed the government's process of procuring information technology by
      (1) placing increased attention on the cost effectiveness of information
      technology, the return on the government's investment and resulting
      contractor performance with respect to such technology and (2) making
      individual agencies accountable for oversight of information technology
      budgets. These two trends are expected to result in increased interagency
      coordination and sharing of expenses, and fewer proprietary or single
      agency solution systems. Companies such as Anteon and A&T, which are
      well-positioned across several major governmental agencies, should benefit
      from these trends.

    - INCREASED USE OF COMMERCIAL OFF-THE-SHELF HARDWARE AND SOFTWARE. The
      Federal government has sought to address an increasing portion of its
      information technology needs through relatively inexpensive, open
      architecture systems based on commercial off-the-shelf ("COTS") hardware
      and software, which are rapidly displacing the single purpose, custom
      systems historically favored by the Federal government. These hardware and
      software products are, unlike proprietary systems, more open, modular and
      scaleable, and in some instances even better suited to meet governmental
      needs. The implementation and usage of COTS products are expected to
      increase as the government seeks to ensure the compatibility of its
      systems across agencies. In addition, the continued shortening of software
      upgrade cycles is expected to increase the demand for new products. These
      trends will favor system integrators such as Anteon and A&T, who have a
      deep knowledge of their customers and systems through years of performing
      contracts, as well as extensive expertise in COTS solutions.

    - INCREASED MODELING, TRAINING AND SIMULATION. Because of the high cost of
      weapon systems development, testing and field training, there is increased
      reliance on modeling and simulations using software applications (from the
      conceptual design of weapons to their operations and maintenance and the
      training of personnel), training simulators and other mission rehearsal
      techniques. Anteon has significant experience in designing and
      implementing such systems and programs for a variety of customers, such as
      the Air Force and U.S. Navy. Management believes that this experience will
      permit Anteon to obtain future new awards.

                                       49
<PAGE>
                                    BUSINESS

    Anteon is a leading provider of advanced information technology and
engineering systems and services. We serve hundreds of governmental clients,
principally within the U.S. Federal government, from 39 offices worldwide. We
have performed work for the U.S. Congress and all 14 Cabinet-level government
agencies, designing, maintaining and upgrading critical systems such as defense,
intelligence, emergency response, logistics support and financial management
systems. For the year ended December 31, 1998, we performed work on
approximately 3,000 task orders on more than 500 contracts. In addition, during
the past four years, we have increased revenues at a 32.0% compound annual
growth rate including a 19.9% compound annual growth rate excluding
acquisitions. Pro forma for the acquisition, our 1998 revenues and Adjusted
EBITDA were $450.8 million and $35.1 million, respectively. Cash flows used in
operating activities on a pro forma basis were $2.3 million for 1998.

    The Federal government is among the world's largest purchasers of
information technology, with total expenditures in fiscal 1999 expected to be in
excess of $30 billion and expected to increase by approximately 4.4% per annum
from $29.5 billion in 1998 to $35.1 billion in 2002. Due to projected increased
Federal government outsourcing, the amount of information technology services
procured from contractors is expected to increase at a faster rate, by
approximately 6.9% per annum from 1998 to 2002. We believe that the emphasis of
the Federal government on downsizing and budget constraints for large new
projects will continue to result in the increased use of technology to enhance
productivity with expenditures focused on upgrading existing equipment and
systems, including many that we designed and are currently supporting. In this
environment, contractors like us that are capable of providing complete
end-to-end technology services across a number of applications and are
well-positioned to take advantage of the opportunities presented by these
trends.

    We have developed over a 22-year period the expertise and capabilities to
deliver a broad range of technology solutions. For example, we are currently
working with the U.S. Federal Emergency Management Agency to design and
integrate the National Emergency Management Information System, a management
information system that enables the White House and other governmental offices,
to effectively monitor and mobilize multiple agencies and financial resources in
response to national emergencies. This program is the largest WindowsNT
implementation in the Federal government and we believe it is the most
comprehensive emergency management system available. In addition, we believe
there is significant potential for generating additional revenues based on the
knowledge we have acquired in designing and integrating this system and its wide
applicability to other government agencies and projects. Another example of our
work is the logistics system we developed for the U.S. Air Force called Cargo
Movement Operation System ("CMOS"). CMOS tracks all equipment and cargo movement
operations for the Air Force world wide. This system is the first standard U.S.
Air Force client/server application to be installed. CMOS is currently installed
at air bases worldwide, and was recently chosen by the Office of the Secretary
of Defense to be the model transportation system for the Department of Defense.
As a result of developing and integrating CMOS, we were recently awarded another
major logistics automation contract to develop a model logistics system to
manage the transportation requirements of all branches of the U.S. armed forces.

    On March 7, 1999, we entered into a definitive agreement to acquire A&T. A&T
is a market leader in undersea warfare, acoustics, command and control and
training support and in many instances is a national repository of acoustical
and hydrodynamic technologies. The acquisition will strengthen and broaden our
customer and contract base and will complement our extensive presence as a
leading supplier to the U.S. Navy, combining Anteon's surface ship systems
capabilities with A&T's strength in submarine and undersea warfare. In addition,
this acquisition provides vertical integration of our skill set, enhancing our
ability to provide services across the complete project life-cycle from concept
to implementation to support. A&T's early stage engineering capabilities in
design, requirements analysis and technology development will complement
Anteon's late stage capabilities and track record of executing and integrating
complex technological systems. Finally, the acquisition also expands our
presence at key client locations

                                       50
<PAGE>
and adds an experienced management team. With the acquisition of A&T, Anteon
will increase its 1999 pro forma revenues and Adjusted EBITDA to $450.8 million
and $35.1 million, respectively. Cash flows used in operating activities on a
pro forma basis were $2.3 million for 1998.

COMPETITIVE STRENGTHS

    We attribute our growth and performance to several factors, including the
following:

    - BROAD ENGINEERING AND INFORMATION TECHNOLOGY CAPABILITIES. We have
      developed comprehensive information technology and engineering expertise
      and capabilities over our 22-year history of providing support for
      critical applications within the Federal government's military and
      intelligence infrastructure. Our employees are highly trained, enabling us
      to provide services for many complex governmental systems, including
      defense, intelligence, emergency response, logistics support and financial
      management.

    - LEADING FEDERAL GOVERNMENT SYSTEMS INTEGRATOR AND STRONG REPUTATION. We
      believe that the Federal government primarily uses three criteria in
      seeking suppliers of technical systems and services: the ability to
      deliver a broad range of sophisticated technical capabilities; a track
      record of excellence in servicing the needs of the Federal government; and
      the ability to deliver at a competitive price. Based on these criteria, we
      have developed a reputation as a premier provider to the Federal
      government and we have received numerous awards for our broad technical
      expertise and consistently high quality performance. We were recently
      ranked as the No. 1 systems integrator in a survey of over 1,200 Federal
      government customers by FEDERAL COMPUTER WEEK, a leading publication in
      the Federal government information technology sector. We believe that our
      demonstrated capabilities and reputation for service excellence have
      allowed us to maintain our position as an incumbent service provider on
      100% of our major contracts that have been recompeted over the past three
      years.

    - DIVERSE CUSTOMER AND CONTRACT BASE; STRONG INCUMBENT POSITIONS. We have a
      diverse customer base with hundreds of governmental clients worldwide,
      which has included all 14 Cabinet-level agencies and all branches of the
      military. In 1998 we performed work on approximately 3,000 task orders,
      and since 1996 we have completed approximately 7,000 task orders for our
      clients. In executing these orders, we have acquired extensive knowledge
      of the particular information technology needs of our clients, and we
      believe that our typical position as the incumbent designer and integrator
      enables us to anticipate their changing technical requirements. These
      factors often position us as the preferred provider of ongoing support,
      upgrades and next generation systems development. As a result of these
      relationships we have developed a backlog of approximately $1.1 billion
      (and, after giving pro forma effect to the Acquisition, a backlog of $2.1
      billion as of June 30, 1999, providing significant predictability of
      revenues. For a further discussion of management's calculation of our
      backlog, see "--Backlog."

    - STRONG OPERATIONS MANAGEMENT; LOW COST STRUCTURE. Our focus on control of
      indirect costs and cost center flexibility has permitted us to increase
      profitability and we believe that we have achieved one of the lowest cost
      structures in the industry. Management has developed rigorous control
      procedures to mitigate losses in "at risk" situations where task order
      performance has commenced but funding or appropriation has not been
      formally authorized or where contract performance has begun because
      management considers the award of a contract to be imminent. We also
      employ management information and resource management systems to maximize
      operational efficiency and reduce indirect costs. Our indirect costs have
      been reduced to 15% of revenues in 1998 compared to an industry peer group
      average estimated by management to be between 18% to 20%, and we have
      increased EBITDA margins from 1.9% in 1995 to 6.6% in 1998 (after giving
      pro forma effect to the Techmatics acquistion).

                                       51
<PAGE>
    - WELL-POSITIONED TO CAPITALIZE ON INDUSTRY GROWTH. Federal government
      information technology spending will total approximately $30 billion in
      1999 according to the OMB and is expected to increase to $35.1 billion in
      2002. In addition, the outsourced portion of this spending is expected to
      increase from 78% in 1998 to 86% in 2002. Due to this increased
      outsourcing, the amount of information technology services procured from
      contractors is estimated to increase at 6.9% per year from 1998 to 2002.
      Anteon believes that growth in Federal government information technology
      spending will be driven by government downsizing, increased outsourcing
      and increasing attempts to utilize more efficient means of procurement. We
      expect a significant portion of this growth to be derived from major
      government-wide acquisition contract vehicles, such as the $25 billion GSA
      ANSWER multiple-award contract and the $10 billion Department of
      Transportation ITOP II multiple-award contract. We are one of a limited
      number of qualified suppliers under both of these major contract vehicles.
      We believe that our size, capabilities, reputation and long-standing
      relationships combined with our position as incumbent supplier to many
      Federal government agencies, position us to capitalize on the
      opportunities presented by these industry trends.

    - STRONG MANAGEMENT AND HIGHLY EXPERIENCED BOARD. Each of the five senior
      members of Anteon's management team has over 20 years of experience in
      managing both small and large companies in both the defense and commercial
      markets. In addition, several members of management and the Board of
      Directors are former military officers or senior government officials who
      are familiar with the information technology requirements of government
      agencies. Dr. Paul Kaminski, a director of Anteon, recently served as
      Under Secretary of Defense for Acquisition and Technology. Mr. Gilbert
      Decker, a Director of Anteon, recently served as Assistant Secretary of
      the U.S. Army for Research, Development and Acquisition, and in that
      capacity led the Army's acquisition and procurement reform efforts. Our
      management team is responsible for our growth and improved profitability
      in the current procurement environment and has a significant equity stake
      in Anteon through direct investment and equity-based incentives.

BUSINESS STRATEGY

    We believe that a key element of Anteon's success is its high standard of
performance and customer service. Past performance is one of the three critical
elements the government employs to evaluate information technology suppliers.
Our demonstrated performance record and service excellence have enabled us to
maintain our position as an incumbent service provider on 100% of our major
contracts that have been recompeted over the past three years. We believe that
our high-level technical abilities and low cost structure will allow us to
further expand our customer base, improve our operating results and continue to
grow. Specifically, we will pursue the following business strategies:

    - BROADEN CAPABILITIES. We continually seek to acquire new expertise and
      keep pace with developments in technology by acquiring and training our
      employees and acquiring technologies to complement our skill set. We are
      aggressively pursuing several new disciplines that complement our existing
      technology capabilities. Particular areas of expertise we are pursuing
      include network communications, remote sensor information processing,
      geographic information systems and information security. We also seek to
      broaden our technology skills by providing extensive training to new and
      current employees. For example, we have an extensive in-house,
      computer-based training program consisting of over 150 courses. These
      efforts will enable us to remain at the forefront of information
      technology applications and be more responsive and flexible in servicing
      the needs of our customers.

    - LEVERAGE EXPERIENCE AND REPUTATION TO EXPAND MARKET SHARE. We have
      performed a variety of services for a diverse base of customers, including
      hundreds of governmental clients worldwide, including all Cabinet-level
      agencies and all branches of the military. The new Federal government
      procurement environment has reduced the number of suppliers and favors
      those companies with experience and broad capabilities. We plan to
      leverage our comprehensive capabilities and our

                                       52
<PAGE>
      position as the incumbent provider on critical Federal government
      applications to provide complete end-to-end services including new systems
      development, integration, upgrades, maintenance, support and training. To
      support our plans, we have increased our national and global presence,
      opening offices in Albuquerque, New Mexico; Colorado Springs, Colorado;
      Australia and Asia. We have also acquired a comprehensive new business
      development and bidding software system, known as WinAward, which scans
      for and targets new programs or task orders which require skills and
      services particularly suited to Anteon's capabilities. This system
      provides early identification of prospects, allowing us to mobilize the
      resources necessary to win the award.

    - CONTINUE TO IMPROVE OPERATING AND FINANCIAL PERFORMANCE. We believe that a
      key element of our success in the Federal government market has been our
      continuous pursuit of cost reductions and focus on working capital
      management. We have developed and employ integrated management information
      and resource management systems and policies that have enabled us to
      maintain indirect cost levels that we believe are among the lowest in the
      industry. We will continue to leverage our operating efficiency and risk
      management capabilities to bid aggressively on contracts to further
      improve our operating and financial performance.

    - PURSUE STRATEGIC ACQUISITIONS. We believe the changes in the government
      procurement market will result in continuing consolidation opportunities.
      We will selectively review acquisition candidates with a focus on
      companies having complementary skills and established positions in key
      segments of the marketplace that provide opportunities for revenue
      enhancement or a reduction in indirect costs. A key element of all
      acquisitions is the existence of rigorous risk management procedures and
      strong operational management.

ANTEON DIVISIONS

    We provide our services through five operating divisions (including our
subsidiaries): Techmatics, the Federal Information Technology Group, Vector
Data, the Enterprise Solutions and Services Group and the GSA Programs Group.
The following is a brief description of each of Anteon's divisions and examples
of some of the projects and programs Anteon has performed for its government
clients.

TECHMATICS

    Techmatics has over 15 years of experience in supporting U.S. Navy
technology acquisition programs. The Techmatics Division provides systems
engineering and systems development, mission and threat analysis and acquisition
management services to most major ship and weapon system acquisition projects
currently in progress in the U.S. Navy. Techmatics has been a team member in the
development and acquisition of the U.S. Navy's AEGIS cruisers and destroyers,
the U.S. Navy's Theater Air Defense strategy and National Missile Defense
planning, as well as the latest submarine, aircraft carrier and amphibious
designs. The division's client base is predominantly the U.S. Navy and includes
approximately 30 customers or agencies within the U.S. Navy. Projects on which
Techmatics is engaged include the Ballistic Missile Defense Program, the Cruise
Missile Defense Program, the Ship Self Defense Program and the Navy Theater Air
Defense program.

    - NAVY THEATRE BALLISTIC MISSILE DEFENSE PROGRAM. An example of
      Techmatics' work is the service it performed in connection with the
      Navy Theater Ballistic Missile Defense Program. In January 1999,
      Techmatics was awarded a $63 million five-year IDIQ contract to
      provide professional, technical and management services to support the
      Navy Theater Ballistic Missile Defense Program. The purpose of the
      Ballistic Missile Defense Program is to place on each ship in the
      program a defense system that will use missiles on board to counter
      and destroy incoming enemy missiles. While the program itself will
      cost several billions of dollars and will be developed by major
      government defense prime contractors such as Lockheed Martin and
      Raytheon, Techmatics supports and advises the U.S. Navy in
      implementing this program. In

                                       53
<PAGE>
      this capacity, Techmatics works in close partnership with U.S. Navy
      departments in evaluating alternatives on systems engineering, systems
      requirements, software and hardware. Management believes Techmatics,
      with its long history of technical support on naval projects and large
      number of experienced former naval officers, is well-positioned to
      fill this role for the U.S. Navy.

      Techmatics' extensive experience on earlier U.S. Navy projects allowed
      us to develop the expertise and establish relationships necessary to
      bid successfully for the Navy Theater Ballistic Missile Defense
      Program. Techmatics was solicited to make a bid and, because of our
      longstanding incumbent position and institutional knowledge,
      Techmatics was the only contractor to bid for the project. Because of
      these relationships, Techmatics was also recently selected to provide
      systems engineering support for the next generation destroyer, the new
      attack submarine and the aircraft carrier programs. We believe that
      due to our established relationships and track record with the U.S.
      Navy, we have a competitive advantage when bidding for similar
      projects in the future.

    - U.S. NAVY AEGIS PROGRAM. AEGIS is largely considered to be the world's
      most advanced air defense system, and is composed of over 50 cruisers
      and destroyers equipped with a sophisticated computer controlled
      missile engagement system. The heart of the AEGIS capability is a
      multifunction, phased array radar system. Due to the solid reputation
      AEGIS has developed, the AEGIS Combat System has also been installed
      on four Japanese Maritime Self Defense ships and the Spanish Navy is
      building AEGIS equipped ships. Techmatics supports all aspects of this
      program, including ship design, construction and maintenance; AEGIS
      Combat System engineering and testing; and the engineering and
      introduction of a Theater Ballistic Missile Defense capability in
      AEGIS. Recently, the AEGIS programs were merged with all surface ship
      air defense efforts in the Program Executive Office for Theater
      Surface Combatants. Techmatics provides engineering and technical
      support to this consolidated organization.

FEDERAL INFORMATION TECHNOLOGY GROUP

    The Federal Information Technology Group focuses on providing information
technology services to the U.S. Army, U.S. Air Force, Defense Finance and
Accounting Service, Federal Emergency Management Agency ("FEMA"), Bureau of
Indian Affairs and selected additional government and commercial organizations.
The division provides system integration and full end-to-end information
technology services. The division provides its services through multiple
contract vehicles including GSA Schedule, GSA CAPZONE, GSA ANSWER and Department
of Transportation ITOP. Within these contract vehicles, we execute our work
through hundreds of contracts or task orders.

    - FEDERAL EMERGENCY MANAGEMENT AGENCY. An example of the services our
      Federal Information Technology Group provides is our support for FEMA.
      FEMA works in coordination with state and local government to provide
      a federal response to emergencies, such as tornadoes, hurricanes,
      earthquakes or fires). In 1995, FEMA hired Anteon to develop a system
      to assist it in managing disaster operations on-site at its regional
      offices and at its headquarters. In response, Anteon developed the
      National Emergency Management Information System ("NEMIS"). NEMIS is
      an enterprise-wide Oracle-based client/server management information
      system that connects several thousand desktop and mobile
      terminals/handsets and provides FEMA with a fully mobile, nationwide
      response and disaster management system. Anteon worked with FEMA over
      a 2 1/2-year period to build NEMIS. Over 100 analysts and software
      technicians were involved in all major aspects of designing and
      implementing this project. To date, the Federal government has spent
      approximately $70 million on the development of NEMIS Version 1. Our
      work on NEMIS Version 1 was critical to our success in being chosen to
      develop NEMIS Version 2, a project which is expected to have a budget
      of approximately $6 million per year. In addition, we continue to
      provide support and maintenance to NEMIS

                                       54
<PAGE>
      Version 1 under a five-year $28 million contract. The NEMIS system is
      the most comprehensive emergency management system available and we
      believe there are significant opportunities to sell this system to
      individual states and foreign governments.

    - CARGO MOVEMENT OPERATIONS SYSTEM FOR THE AIR FORCE. Another example of
      Anteon's achievements is its work on the U.S. Air Force CMOS project,
      which began as a systems development and integration contract and has
      evolved into an end-to-end support relationship. Anteon has been
      supporting CMOS since 1989 when its started to develop this mission
      critical system for the U.S. Air Force to automate cargo movement
      operations. CMOS is one of the largest open systems within the
      Department of Defense, and the first standard Air Force client server
      application to be installed at air bases worldwide. The CMOS project
      involved full systems development, end-to-end support, integration of
      COTS systems and custom developed software, configuration management,
      maintenance implementation, and training. Anteon continues to provide
      support, maintenance and upgrades to CMOS under a multi-year contract.
      During the past ten years, Anteon's involvement in CMOS has generated
      approximately $25.6 million in revenues. Because of Anteon's track
      record as the incumbent services provider for the work performed,
      Anteon acts as sole supplier for task orders under this contract.

    - TC-AIMS PROJECT. As a result of our record of performance on CMOS, we
      have been awarded the Transportation Coordination Automated
      Information Movement Systems ("TC-AIMS") contract through the
      Department of Transportation ITOP II contract. TC-AIMS is using the
      CMOS system as a model to develop a transportation and deployment
      management system that will coordinate critical logistics requirements
      throughout the Department of Defense. CMOS was chosen as the model
      system for TC-AIMS by the Office of the Secretary of Defense. While
      TC-AIMS is similar in function to CMOS, it will have broader
      capabilities and will be used in one single combined system with other
      service systems. TC-AIMS will also be used for the redeployment and
      recovery of troops and equipment. Anteon currently has approximately
      46 people working on the TC-AIMS contract.

VECTOR DATA

    Vector Data provides systems engineering including what is known in the
defense industry as command, control, computers, communications, intelligence,
surveillance and reconnaissance ("C(4)ISR") services to national and
international defense organizations. Vector Data provides services and support
worldwide for NATO and other coalition warfare, strategic and tactical
communications, imagery exploitation and mission rehearsal from the beginning
stages of a program through its entire life. The division's client base
includes, among others, the U.S. Department of Defense, NATO and the U.K.
Ministry of Defense. Vector Data's support of C(4)ISR systems such as Linked
Operations/Intelligence Centers Europe ("LOCE") has been critical in providing a
common structure and set of standards that allow for the rapid distribution and
exchange of tailored intelligence data to support coalition operations in peace,
crisis and war.

    - LINKED OPERATIONS/INTELLIGENCE CENTERS EUROPE PROGRAM FOR NATO. Vector
      Data provides on-site maintenance support to the LOCE program. The
      LOCE program provides a common view of intelligence derived from
      multiple sources for the United States, NATO and U.N. peacekeeping
      forces in Europe. Near-real time intelligence is available through
      such technology as imagery, shared early warning systems, and
      interfaces with other U.S. and NATO systems. We support the LOCE
      program by providing software and hardware maintenance, communications
      engineering, formal classroom and on-site training, and
      hardware/software configuration management. We also provide
      responsive, on-site daily customer service from the U.S., Italy, U.K.,
      and Germany. Vector Data is in its third contract on this project and
      is currently the sole-source provider.

      internet based training system for courses with job specific content.
      By developing a system that documents job specific content
      electronically, the student is able to access information on a
      just-in-time basis, thereby reducing the time spent in training by
      over 30%.

CONTRACT PROFILE

ANTEON

    Anteon is one of a select group of qualified suppliers of information
technology services to the Federal government under multiple long-term contract
vehicles. Anteon performed work on approximately 7,000 task orders under such
contracts in the past three years and we are performing work on approximately
3,000 task orders. No one task order accounted for more than 5% of total 1998
revenues. In 1998, approximately 47%, 34% and 19% of Anteon's revenues were
generated by time and materials contracts, cost-plus contracts and fixed price
contracts, respectively.

    Management believes that Anteon has secured a place as a prime contractor or
a subcontractor for every major government-wide acquisition contract issued
since January 1996. We have been awarded two major contracts as a prime
contractor since the second quarter of 1998. The GSA ANSWER contract is a
10-year multiple-award contract with an overall contract value of $25 billion.
We were previously the incumbent supplier on task orders under the predecessors
to this contract vehicle (GSA PACZONE and CAPZONE). The Department of
Transportation ITOP II contract is a 7-year multiple-award contract with an
overall contract value of $10 billion. The ITOP II contract was awarded to 14
prime contractors, including Anteon.

A&T

    A&T also maintains a diversified contract base with no one contract
accounting for more than 5% of total 1998 revenues. In fiscal year 1999,
approximately 71%, 20% and 9% of A&T's revenues were generated by cost-plus
contracts, fixed price contracts and time and materials contracts, respectively.
However, in October 1998, A&T won a $130 million five-year contract from the
FTSCA, its largest win ever, which represents a significant future growth
opportunity. Over 80% of A&T's work is performed as a government prime
contractor, much of it for the U.S. Navy. Within the E/IT division,
approximately 80% of its work is performed on a cost-plus basis. Within IMC,
most work, both commercial and government, is done on a fixed price basis.

CONTRACTUAL RISK MANAGEMENT

    At each stage of the contracting process, we attempt to reduce financial and
performance risks. At the pre-award stage, we frequently bid through teaming
agreements with other contractors having complementary technical strengths that
enhance the likelihood of winning the contract, including, in many instances,
our main competitors. Sometimes, before a Federal government agency has actually
signed or begun funding for services under a contract or task order, our
employees will begin providing services. We have

                                       60
<PAGE>
internal procedures in place to ensure that such "at risk" provisions of
services only occur when funding is delayed due to bureaucratic or other
technical reasons and it remains highly probable that we will ultimately receive
funding.

    Once we win a contract or task order, we assign a program manager and, at a
lower level, a task leader, to ensure timely and high quality performance of
services. Program managers are given access to our financial management
information systems to assist them in making sure that our incurred costs do not
exceed funded costs under our contracts and task orders. Program managers also
constantly interface with our customers to ensure their needs are being
satisfied.

BACKLOG

    Anteon and A&T, like most of their competitors, possess a substantial
backlog of several hundred contracts that provide multi-year revenues. Most of
our contracts are operational over a one to ten-year period. In the past, we
have generally been successful in substantially expanding the scope and size of
our principal contracts. Pro forma for the acquisition, our estimated total
contract backlog as of June 30, 1999 was $2.1 billion with an additional $155
million of bids outstanding and over $1 billion of identified bid opportunities.

    These backlog amounts consist of "funded" backlog which is based upon
amounts actually appropriated by a customer for payment of goods and services
and "unfunded" backlog which is based upon management's estimate of the future
potential of our existing contracts to generate revenues for Anteon and A&T.
Because the Federal government operates under annual appropriations, agencies of
the Federal government typically fund contracts on an incremental basis.
Accordingly, a significant portion of our total contract backlog is not
"funded." Funded backlog generally varies depending on procurement and funding
cycles and other factors beyond our control. Accordingly, period-to-period
comparisons are difficult and not necessarily indicative of any future trends in
revenues.

    Anteon's and A&T's ability to significantly increase their backlogs during
recent years is the result of their successful track records of maintaining
their respective positions as the incumbent service providers on their contracts
as well as success in winning new business. During 1998, Anteon's and A&T's bid
recompete success rates were 100% and 90%, respectively. Set forth in the table
below is a summary of the aggregate dollar amount of (1) contracts that Anteon
and A&T have retained in competitive rebidding processes and (2) new contracts
attained by each of them from 1996 to 1998.

CUSTOMERS

    We are one of a select group of qualified suppliers of information
technology services to the Federal government. Domestically, Anteon and A&T
service more than 60 agencies, bureaus and divisions of the U.S. Federal
government, Cabinet-level agencies and all branches of the military services,
which customers provide approximately 93% of Anteon's and A&T's aggregate
revenues. State and local governments, international clients and the commercial
sector provide the remaining 7%. Anteon performed work on approximately 3,000
task orders in 1998 under several hundred contracts. A&T also has a diverse
contract base with over 100 contracts. In particular, Anteon and A&T have an
established track record of providing quality services to the U.S. Navy.
Together, Anteon and A&T maintain contracts with approximately 30 different U.S.
Navy organizations. These organizations independently contract for our services
and generate, after giving pro forma effect to the acquisition, approximately
51% of Anteon's and A&T's combined 1998 revenues. The GSA, the Environmental
Protection Agency and FEMA are Anteon and A&T's largest civil government
customers.

    Approximately 66% of IMC's revenues were generated from commercial
customers. These customers include FORTUNE 500 companies primarily in
telecommunications, financial services and information technology. IMC has
developed training systems for companies such as MCI Worldcom, Ameritech, GTE,
Royal Bank of Canada, National City Bank, SmithKline Beecham and Merck.

COMPETITION

    The Federal information technology and engineering services industries are
comprised of a large number of enterprises ranging from small, niche-oriented
companies to multi-billion dollar corporations with a major presence throughout
the Federal government. Because of the diverse requirements of Federal
government clients and the highly competitive nature of large Federal
contracting initiatives, corporations frequently form teams to pursue contract
opportunities. Prime contractors leading large proposal efforts select team
members on the basis of their relevant capabilities and experience particular to
each opportunity. As a result of these circumstances, companies that are
competitors for one opportunity may be team members for another opportunity.

    Anteon frequently competes against well-known firms in the industry as a
prime contractor. Obtaining a position as either a prime contractor or
subcontractor on large government-wide contracting vehicles is only the first
step to ensuring a secure competitive position. Competition then takes place at
the task order level, where knowledge of the client and its procurement
requirements and environment is the key to winning the business. We have been
highly successful in ensuring our presence on contracts and GSA Schedules, and
in competing for work under those contracts. Through the variety of contractual
vehicles at our disposal, as either a prime contractor or subcontractor, we have
the ability to market our services to any Federal agency. Because of our
extensive experience in providing services to a diverse array of Federal
departments and agencies, we have first-hand knowledge of our clients and their
goals, problems and challenges. We believe this knowledge gives us a competitive
advantage in competing for tasks and positions us well for future growth.

    A&T's core Department of Defense market is comprised of a small number of
large players with a diverse portfolio of services from automated data
processing services to outsourcing capabilities, as well as a large number of
smaller firms with specialized capabilities. Management believes that A&T is
well-positioned to remain competitive in this market and to sustain its growth
trends.

EMPLOYEES

    Anteon employs approximately 2,200 personnel, representing a highly trained
and technically proficient work force. These employees support hundreds of
national and international clients from our headquarters in Fairfax, Virginia,
and from 39 offices worldwide. Our workforce is highly educated and experienced
in the defense and intelligence sectors. Functional areas of expertise include
engineering,

                                       62
<PAGE>
computer science, business process reengineering, logistics, transportation,
materials technologies, C(4)I, avionics, finance and acquisition management.
None of Anteon's employees is represented by collective bargaining agreements.
Management believes its relationship with its employees is very good.

    A&T employs approximately 1,700 full-time employees, approximately 1,400 of
whom are professional and technical personnel. A&T's highly talented scientists,
engineers and technicians are experts in signal processing, acoustics, ship
survivability and hydrodynamics. A&T's information technology professionals are
experienced in software engineering and development, system integration,
networking and training. A&T has invested significant resources assembling a
team of respected software engineers specializing in high-level systems
architecture, client/server applications and object-oriented programming. None
of A&T's employees is represented by collective bargaining agreements.
Management of A&T believes its relationship with its employees is very good.

FACILITIES

    Anteon's corporate offices are located in leased facilities in Fairfax,
Virginia. Anteon also leases approximately 411,602 square feet of office, shop
and warehouse space in 39 facilities across the United States, United Kingdom,
South Korea and Australia.

    A&T owns its corporate headquarters located in North Stonington,
Connecticut, which occupies 60,330 square feet of office space. A&T also owns
office and shop space in New London, Connecticut and Butler, Pennsylvania. A&T
presently subleases to tenants approximately 23,000 square feet of its Butler
office space and 20,000 square feet of its New London office space.

    A&T also leases approximately 357,000 square feet of office, shop and
warehouse space in 36 locations across the United States, Australia, and Canada.

LEGAL MATTERS

    Anteon received a demand letter from one of Anteon's subcontractors claiming
approximately $3.2 million in damages arising in connection with Anteon's
decision to terminate the subcontractor. The termination was a result of certain
actions taken by Anteon's customer. Anteon believes there are valid defenses to
such claim and that the matter will not have a material adverse affect on
Anteon's financial condition, results of operations or cash flow. Neither Anteon
nor A&T is involved in any other material legal proceedings except for ordinary
routine litigation incidental to its business which is not otherwise material to
its business or financial condition. From time to time, we or our competitors
file bid protests, as permitted under Federal procurement regulations, in
connection with specific contract awards. Historically, these proceedings have
not had any material effect on Anteon's financial condition, results of
operations or cash flow. Management is not able to assure you that either
company will not become involved in material legal proceedings or contract bid
protest proceedings in the future.

                   OVERVIEW OF FEDERAL GOVERNMENT CONTRACTING

GOVERNMENT BIDDING OVERVIEW

    There are several different processes through which a Federal government
agency will solicit bids. The following is a summary of the typical bidding
process which government contractors such as Anteon and A&T encounter. If a
Federal government agency has a requirement, such as the upgrade of a management
information system, the agency makes a brief announcement of its requirements in
the COMMERCE BUSINESS DAILY or on a government electronic bulletin board to
which contractors like Anteon and A&T have access. Interested contractors then
submit packages expressing their interest and highlighting their qualifications.
The agency responds to those contractors it deems preliminarily qualified by
providing them with a request for a proposal ("RFP") or similar solicitation.
The RFP is an extensive document describing the desired services and terms and
conditions that will form the final agency contract. The RFP includes a
statement of the criteria according to which bids will be evaluated (usually
focusing on price, past performance and quality of technical/management plan).
Bidders then submit proposals in response to the RFP. The agency evaluates all
the proposals and announces the winner. This process can take up to a year.

    The competitive process for a multiple award contract procurement is similar
to that described above, except that the government awards multiple contracts to
a selected group of contractors, rather than a single contract. Federal agencies
desiring to procure goods and services through a particular multi-agency
contract such as GSA ANSWER, will request the servicing agency (for example,
GSA) to initiate a limited competition among the selected awardees, resulting in
the issuance of a task order to a single contractor. A task order calls for a
specific set of services to be delivered by the contractor to a particular
client agency. Competition for task orders among initial awardees can be intense
and often focuses on price, because the initial awardees are already qualified
to supply the service through the initial award of the government contract
vehicle. However, our experience has been that after winning a task order and
effectively providing the requested services, we will typically receive
successive task orders from the same agency for follow-on services. Our
experience has also been that the key factors in bidding successfully for these
Federal government contracts are technical capabilities, past performance,
competitive prices and reputation, all four of which management believes are
factors that strongly favor both Anteon and A&T.

TYPES OF CONTRACT VEHICLES

    The Federal information technology procurement environment has changed
dramatically in recent years. Federal government agencies traditionally procured
information technology solutions through agency-specific contracts awarded to a
single contractor or contractor team. Several statutory and regulatory changes
have significantly altered Federal government procurement practices. The number
of procurement "vehicles" available to Federal government customers to satisfy
their requirements has increased dramatically in recent years. Federal
government agencies are now more likely to use flexible contract vehicles that
permit multiple sources to compete for specific orders. We believe these trends
are likely to continue.

    IDIQ contracts are essentially umbrella contracts that set forth the basic
terms and conditions under which the Federal government may order goods and
services from one, and in some cases, more than one, contractor. Such contracts
will also specify the labor and other costing rates that will apply to services
that may be the subject of task orders under those contracts. IDIQ contracts may
be awarded to a single contractor, or to multiple contractors. Multiple-award
IDIQ contracts are increasingly being used for large-scale Federal government
purchases of services and/or integrated systems that may include a significant
service or maintenance component, along with the provision of computer hardware
and software. The periods of performance for IDIQ contracts usually span a base
year and a number of option years. IDIQ contracts do not obligate the Federal
government to purchase goods or services at the maximum levels set forth in the
contract.

                                       64
<PAGE>
    Federal government agencies also frequently purchase information technology
services and products through other contract vehicles such as GSA Schedules. GSA
awards such indefinite quantity fixed price contracts to companies for stated
periods of time through which individual agencies may place orders, receive
shipments and make payments directly to contractors. In order for a company to
provide services under a GSA contract, the company must be pre-qualified and
selected by the GSA. In the information technology service sector the three
ratings criteria employed by the GSA for pre-qualification are technical skills,
price and a history of excellence in government contract administration. Anteon
and A&T both have GSA Schedule contracts.

    The changed environment for Federal government contractors presents a number
of challenges for companies like Anteon. In the case of contracts like GSA
Schedule contracts or IDIQ contracts, a substantial amount of marketing must be
done after winning the initial contract in order to win subsequent delivery and
task orders.

    Our experience has been that the changed environment for government
contractors has on balance been highly favorable to companies like Anteon that
have a wide range of technological capabilities, are very focused on cost
control and have a high degree of sophistication and experience in government
contracting. First, these more flexible forms of contract vehicles provide for
very sizable revenue generation opportunities. Some of our IDIQ contracts
potentially involve billions of dollars of revenues for awardees. Second, these
vehicles permit us to market our services to a much wider range of customers
than was possible under more traditional contracting vehicles. Third, the
current environment tends to favor entities that have the size and technological
breadth to offer a variety of services because the umbrellas provide for broader
opportunities. Finally, we have found that this environment encourages building
longer term and stable supplier/customer relationships because there are often a
number of contract vehicles under which Federal agencies may be able to direct
work to preferred contractors. This tends to lessen the risks to customer and
supplier of going through recompetes in order to continue to transact business,
and provides a reward for suppliers such as Anteon that establish a reputation
for quality and integrity.

CONTRACT PAYMENT TYPES

    The contract vehicles described above employ various payment methodologies.
Contracts are typically referred to as time and materials contracts, cost-plus
contracts and fixed-price contracts. Each of these contract payment types is
described below.

    TIME AND MATERIALS CONTRACTS

    Some of our largest contracts are negotiated on the basis of time and
materials. Under this type of contract, a contractor is paid a fixed hourly rate
for direct labor hours expended. Labor costs, overhead and profit are included
in the fixed hourly rate. Materials, subcontractors and other direct costs are
reimbursed at actual cost-plus general and administrative expenses and, in some
instances, an agreed-upon percentage of profit. A contractor makes critical
pricing assumptions when proposing fixed labor rates for a time and materials
contract and risks loss of profitability on time and materials contracts if its
actual costs exceed assumed costs made. In 1998, time and materials contracts
accounted for approximately 46.7% of Anteon's revenues, approximately 9.4% of
A&T's revenues, and approximately 32.7% of Anteon's revenues pro forma for the
acquisition.

    COST-PLUS CONTRACTS

    Cost-plus contracts provide for reimbursement of costs, to the extent that
such costs are allowable, and the payment of a fixed "fee," which is essentially
the profit negotiated between the contractor and the contracting agency.
Cost-plus incentive fee and cost-plus award fee contracts provide for increases
or decreases in the contract fee, within specified limits, based upon actual
results as compared to contractual targets for factors such as cost, quality,
schedule and performance. In fiscal 1998, cost-plus contracts

                                       65
<PAGE>
accounted for approximately 34.2% of Anteon's revenues, approximately 70.6% of
A&T's revenues, and approximately 47.8% of Anteon's revenues pro forma for the
Acquisition.

    FIXED PRICE CONTRACTS

    Under fixed price contracts, a contractor agrees to perform specified work
for a fixed-price and, accordingly, risk of performing the contract. In fiscal
1998, fixed price contracts accounted for approximately 19.2% of Anteon's
revenues, approximately 20.0% of A&T's revenues, and approximately 19.5% of
Anteon's revenues giving pro forma effect to the acquisition.

FEDERAL GOVERNMENT RECEIVABLES

    Almost all of our accounts receivable is derived from Federal government
agencies. An account receivable from a Federal government agency enjoys the
overall credit worthiness of the Federal government, even though each such
agency is a separate agency with its own budget. Pursuant to the Prompt Payment
Act, payments from government agencies must be made within 30 days of final
invoice or interest must be paid.

REGULATION

    The passage of the ITMRA in late 1996 resulted in major changes in Federal
government procurement rules governing the acquisition of information technology
goods and services. The ITMRA changed the government's process for procuring
information technology by (1) placing increased attention on the
cost-effectiveness of information technology, return on investment and
performance and (2) allocating to individual agencies authority and
accountability for information technology budgets. These trends are expected to
result in increased interagency coordination and sharing of expense and fewer
proprietary or single agency solution systems. Companies such as Anteon and A&T
which are well-positioned across several major government agencies should
benefit from these trends. As a result of the ITMRA, multiple-award IDIQ
government-wide contracts as the preferred vehicle for procuring information
technology. Accordingly, contractors have a decreased need for large-scale
investment in bid and proposal activities and an increased need to commit
marketing resources to identify and capture tasks under existing contracts.

    Federal government contracts are subject to the Federal Acquisition
Regulations ("FAR") and other agency FAR supplements. Major contracts are also
subject to the Truth in Negotiations Act ("TIN Act") and Cost Accounting
Standards ("CAS"). Among other procurement regulations, the FAR contains the
cost principles for setting contract prices while the TIN Act requires us to
provide current, accurate and complete cost or pricing data in connection with
the negotiation of a contract. CAS requires consistency of accounting practices
over time and compliance with specific cost accounting criteria.

    To the extent that a company fails to comply with procurement requirements,
the Federal government may adjust contract prices. Additionally, changes in cost
accounting practice are subject to a required procedure for negotiation of the
cost of the change. The Federal government is protected from paying increased
costs resulting from accounting changes. Finally, the Federal government has the
right to audit contractors for three years after final payment. Such audits are
generally performed by the DCAA. Accordingly, Anteon's revenues are subject to
adjustment.

                                THE TRANSACTIONS

THE ACQUISITION

    On March 7, 1999, Anteon entered into an agreement and plan of merger to
acquire all of the issued and outstanding shares of A&T common stock at a price
of $26.00 per share. Under the merger agreement, Buffalo Acquisition
Corporation, a Connecticut corporation and wholly-owned subsidiary of Anteon,
merged into A&T and A&T became a wholly-owned subsidiary of Anteon. We completed
the acquisition on June 23, 1999.

    IMC CONTINGENT PAYMENT, STOCK OPTIONS AND RETENTION ARRANGEMENTS

    IMC, a subsidiary of A&T, acquired all the outstanding stock of UP, Inc.
("UP") under a stock purchase agreement among A&T,  IMC and the former
stockholders of UP (the "UP Sellers"), dated as of November 14, 1997 (the "UP
Stock Purchase Agreement").

    The UP Stock Purchase Agreement provided for a contingent payment to be made
to the UP Sellers (the "UP Contingent Payment") which became due and payable
upon consummation of the merger. The UP Contingent Payment to all of the UP
Sellers equals, at their election, either (a) 81,100 shares of common stock of
IMC (which would equal 9.1% of the outstanding shares of IMC after issuance but
before exercise of options to purchase IMC stock as described below), (b)
$2,250,000 in cash or (c) a combination of shares and cash which equals the
appraised value of the 81,100 shares of IMC, however, the Sellers may not elect
to receive more than $2,250,000 in cash. The management of A&T believes that it
is likely that the appraised value of the 81,100 shares of IMC will be less than
the cash payment alternative of $2,250,000, and this prospectus assumes that all
the UP Sellers elect to receive cash and are not entitled to receive any shares
of IMC stock by reason of the UP Contingent Payment. In addition, if the UP
Sellers elect to receive cash for the UP Contingent Payment, they will also be
granted options to purchase an additional 81,100 shares of common stock of IMC
in the aggregate at an exercise price of $27.74 per share.

    In addition, IMC has issued to certain of its key employees options to
purchase an aggregate of 180,000 shares of common stock of IMC which would
constitute 18.2% of the outstanding shares of stock, after exercise, assuming
that no shares of IMC common stock are issued as part of the UP Contingent
Payment. Under the agreements pursuant to which these options were granted, the
options fully vested upon the consummation of the merger. IMC and A&T have the
right to purchase such options for a purchase price equal to the difference
between the exercise price of the options and a formula price, called the Parent
Company Change in Control Price under such agreements. The exercise price of the
options is $11.78 per share.

    IMC has also entered into agreements with certain of its employees pursuant
to which they will be entitled to receive retention bonuses in the aggregate
amount of approximately $800,000 if they are still employed by IMC, A&T or any
successor thereof eighteen months following the consummation of the merger, or
if their employment is involuntarily terminated prior to that date other than
for cause.

NEW CREDIT FACILITY

    Anteon entered into the new credit facility with Credit Suisse First Boston,
as administrative agent and advisor and arranger, Mellon Bank N.A., as
syndication agent, Deutsche Bank AG, as documentation agent, and a syndicate of
financial institutions, including CSFB, Mellon and Deutsche Bank. The new credit
facility consists of a $60.0 million term loan facility and a $120.0 million
revolving credit facility. At the closing of the acquisition, Anteon borrowed
$60.0 million under the term loan facility. The undrawn portion of the revolving
credit facility will be available to us for general corporate purposes,
including additional permitted acquisitions and investments. See "Description of
Other Material Agreements--New Credit Facility" for additional information on
the new credit facility.

EQUITY CONTRIBUTION

    Before the acquisition, Azimuth Technologies, Inc., our parent company, an
affiliate of Caxton-Iseman Capital, contributed $22.5 million to our equity. The
equity contribution was funded by persons who are indirectly existing investors
in Azimuth, or their affiliates, through a limited liability company that is
indirectly controlled by Mr. Frederick Iseman.

OMNIBUS STOCK PLAN

    In January 1997, the Board of Directors adopted, and Anteon's sole
stockholder approved, Anteon's Omnibus Stock Plan and on April 3, 1998 the Board
of Directors adopted, and Anteon's sole stockholder approved, Anteon's Amended
and Restated Omnibus Stock Plan (as amended, the "Plan") which enables Anteon to
make grants of stock-based incentive compensation to officers and other key
employees and consultants of Anteon and its subsidiaries. The purposes of the
Plan are to promote the long-term growth and profitability of Anteon and its
stockholders by (i) providing key people with incentives to improve stockholder
value and to contribute to the growth and financial success of Anteon and (ii)
enabling Anteon to attract, retain and reward the best available persons for
positions of substantial responsibility. The principal provisions of the Plan
are summarized below. This summary, however, does not purport to be complete and
is qualified in its entirety by the terms of the Plan, which may be obtained
from Anteon upon request.

    The Plan is administered by the Board of Directors or, in the alternative, a
committee (the "Committee") appointed by the Board of Directors consisting of
not less than three members of the Board of Directors to administer the Plan on
behalf of the Board, subject to such terms and conditions as the Board may
prescribe. The members of the Committee are required to be both "Non-Employee
Directors" (within the meaning of Rule 16b-3 promulgated under the Securities
Exchange Act of 1934) and "outside directors" (within the meaning of section
162(m) of the Internal Revenue Code of 1986 (the "Code")) to the extent Rule
16b-3 and Code section 162(m), respectively, are applicable to Anteon and the
Plan. The Plan is not subject to the Employee Retirement Income Security Act of
1974, as amended or Section 401(a) of the Code.

    The Plan became effective upon approval of the stockholders in January, 1997
and will remain in effect until January 30, 2007 unless sooner terminated by the
Board. On July 24, 1998, by resolution of the Board of Directors, and with the
written consent of the sole stockholder of Anteon, the Plan was amended to
increase the number of shares of common stock available for award under the Plan
from 250,000 shares to 325,000 shares and on July 23, 1999, by further
resolution of the Board of Directors, and with the consent of the stockholders
of Anteon, the Plan was amended to increase the number of shares of common stock
available for award under the Plan from 325,000 shares to 575,000 shares. The
Board of Directors may amend, alter, suspend, discontinue, or terminate the Plan
or any portion thereof at any time; provided that no such action may be taken
without stockholder approval if such approval is necessary to comply with

                                       73
<PAGE>
any tax or regulatory requirement, or rule of any exchange or Nasdaq system on
which the shares of common stock of Anteon may then be listed or quoted,
including any stockholder approval required for continued compliance with Rule
16b-3 or to enable the Committee to grant incentive stock options pursuant to
the plan. The Committee is authorized to make minor or administrative
modifications to the plan including those dictated, authorized or made desirable
by requirements of applicable federal or state laws. The Committee may also
amend or modify any outstanding award to the extent that it would have had the
authority to make such award as so modified or amended. The Committee has full
power and authority to administer and interpret the plan and to adopt such
rules, regulations, agreements, guidelines and instruments for the
administration of the plan and for the conduct of its business as the Committee
deems necessary or advisable and to interpret same, all within the Committee's
sole and absolute discretion; provided that no such action which would impair
the rights of any participant or any holder or beneficiary of any award may be
taken without the consent of the affected participant, holder or beneficiary.

    The plan authorizes the grant of awards to participants with respect to a
maximum of 325,000 shares of common stock. Any shares covered by awards which
are forfeited, expire or which are terminated or canceled for any reason (other
than as a result of the exercise or vesting of the award) will again be
available for grant under the plan. In addition, in the event of a
reclassification, recapitalization, stock split, stock dividend, combination of
shares or other similar event, the maximum number and kind of shares reserved
for issuance or with respect to which awards may be granted under the plan are
required to be adjusted to reflect such event, and the Committee is required to
make such adjustments as it deems appropriate and equitable in the number, kind
and price of shares covered by outstanding awards made under the plan, and in
any other matters which relate to awards and which are affected by the changes
in the common stock referred to above.

    The Committee is authorized to make adjustments in the terms and conditions
of, and the criteria included in, awards in recognition of unusual or
nonrecurring events affecting Anteon, or the financial statements of Anteon or
any subsidiary, or of changes in applicable laws, regulations, or accounting
principles, whenever the Committee determines that such adjustments are
appropriate in order to prevent dilution or enlargement of the benefits or
potential benefits intended to be made available under the plan.

    In the event of any proposed change in control (as defined in the Plan), the
Committee is required to take such action as it deems appropriate and equitable
to effectuate the purposes of the plan and to protect the grantees of the
awards, including, without limitation, the following: (i) acceleration or change
of the exercise dates of any award so that the unvested portion of any award
shall become fully vested and immediately exercisable; (ii) arrangements with
grantees for the payment of appropriate consideration to them for the
cancellation and surrender of any award, which shall not be less than
consideration paid for other common stock of Anteon which is acquired, sold,
transferred, or exchanged because of the proposed change in control; and (iii)
in any case where equity securities other than common stock of Anteon are
proposed to be delivered in exchange for or with respect to common stock of
Anteon, arrangements providing that any award shall become one or more awards
with respect to such other equity securities.

    There is no restriction under the Federal securities laws on the resale of
any shares acquired pursuant to the Plan, except that (i) persons who at the
time of the resale are considered "affiliates" of Anteon (by reason of being in
a "control" relationship with Anteon) may resell such shares only pursuant to
Rule 144 under the Securities Act of 1933 or pursuant to a "reoffer prospectus"
which may hereinafter be filed by Anteon as part of a registration statement
relating to the plan and (ii) purchases and sales by corporate officers and
directors of any securities of Anteon are subject to section 16(b) of the
Securities Exchange Act of 1934 and the rules promulgated thereunder relating to
insider short-swing profits.

    Anteon may require that a participant, as a condition to exercise of an
award, and as a condition to the delivery of any share certificate, provide to
Anteon, at the time of each such exercise and each such delivery, a written
representation (i) that the shares of common stock being acquired shall be
acquired by

                                       74
<PAGE>
the participant solely for investment and will not be sold or transferred
without registration or the availability of an exemption from registration under
the Securities Act of 1933 and applicable state securities laws; and (ii) as to
the knowledge and experience in financial and business matters of the
participant and the participant's ability to bear the economic risk of such an
investment, in compliance with applicable law. Anteon may also require that the
participant obtain a "purchaser representative" as that term is defined under
applicable law. The stock certificates for any shares of common stock issued
pursuant to the plan are required to bear a legend restricting their
transferability unless such shares are registered or an exemption from
registration is available under the Securities Act of 1933 and applicable state
securities laws. Anteon may notify its transfer agent to stop any transfer of
shares of common stock not made in compliance with these restrictions. Common
stock may not be issued with respect to an award granted under the plan unless
the exercise of such award and the issuance and delivery of share certificates
for such common stock pursuant thereto comply with all relevant provisions of
law, including, without limitation, the Securities Act of 1933, the Securities
Exchange Act of 1934, the rules and regulations promulgated thereunder and the
requirements of any national securities exchange or Nasdaq system on which the
common stock may then be listed or quoted, and such compliance to be subject to
the approval of counsel for Anteon to the extent such approval is sought by the
Committee.

    Under the plan, the Committee may grant awards in the following forms:
non-qualified stock options, incentive stock options, stock appreciation rights
(including free standing, tandem and limited stock appreciation rights),
restricted stock or unrestricted stock awards, phantom stock, or any combination
of the foregoing. The Committee may grant awards alone, in addition to, in
tandem with, or in substitution for any other award. Awards may be granted for
no cash consideration or for such consideration as may be determined by the
Committee. Each award, and each right under any award, may be exercised during
the participant's lifetime only by the participant, unless otherwise determined
by the Committee or, if permissible under applicable law, by the participant's
guardian or legal representative; and may not be assigned, alienated, pledged,
attached, sold or otherwise transferred or encumbered by a participant other
than by will or by the laws of descent and distribution provided that the
designation of a beneficiary will not constitute an assignment, alienation,
pledge, attachment, sale, transfer or encumbrance for purposes of the plan.

    STOCK OPTIONS

    A stock option granted under the plan provides a participant the right to
purchase, within a specified period of time, a stated number of shares of common
stock at the price specified in the option. Non-qualified and incentive stock
options granted under the plan will be subject to such terms, including exercise
price and the conditions and timing of exercise, as may be determined by the
Committee.

    On and after the date a participant terminates employment with Anteon or any
of its affiliates for any reason, Anteon shall have the right to purchase, and
the participant shall have the corresponding obligation to sell, upon delivery
of written notice to the participant by Anteon, any or all of the participant's
vested options and any or all shares then owned by the participant. The purchase
price of the shares shall be the fair market value of such shares as of the date
Anteon mails or otherwise delivers such written notice to the participant. The
purchase price of any vested option shall be the difference between the exercise
price per share and the fair market value of one share of common stock, measured
as of the date Anteon mails or otherwise delivers such written notice to the
participant, multiplied by the number of shares to which the option relates that
are being purchased. The Committee may in its sole and absolute discretion
deduct from the purchase price payable any and all amounts owed by the grantee
to Anteon at the time that payment of the purchase price is due the participant.
In the event of the participant's disability or death, the provisions of the
plan will apply to the participant's legal representative or guardian, executor,
personal representative, or to the person to whom the option and/or shares shall
have been transferred by will or the laws of descent and distribution, as though
such person is the participant.

                                       75
<PAGE>
    STOCK APPRECIATION RIGHTS

    A stock appreciation right provides the participant the right to receive an
amount equal to the excess of the fair market value of a share of common stock
on the date of exercise of the stock appreciation right over the grant price
thereof. Stock appreciation rights granted under the plan will be subject to
such terms, including grant price and the conditions and limitations applicable
to the exercise thereof, as may be determined by the Committee. Stock
appreciation rights may be granted in tandem with another award, in addition to
another award, or freestanding and unrelated to another award. The Committee is
authorized under the plan to determine whether a stock appreciation right shall
be settled in cash, shares of common stock or a combination of cash and shares
of common stock.

    STOCK AWARDS: RESTRICTED STOCK, UNRESTRICTED STOCK AND PHANTOM STOCK

    Subject to the other applicable provisions of the plan, the Committee may at
any time and from time to time grant stock awards to eligible participants in
such amount and for such consideration, including no consideration or such
minimum consideration as may be required by law, as it determines. A stock award
may be denominated in shares of common stock or stock-equivalent units, and may
be paid in common stock, in cash, or in a combination of common stock and cash,
as determined in the sole and absolute discretion of the Committee from time to
time.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

CAXTON-ISEMAN ARRANGEMENT

    Anteon's management and an investor group organized by Caxton-Iseman
Capital, through Azimuth, acquired in April 1996 all of the outstanding capital
stock of our Predecessor Company, a wholly-owned subsidiary of Ogden Technology
Services Corporation and indirectly a wholly-owned subsidiary of Ogden
Corporation.

    Azimuth obtained the funds required for the acquisition of our Predecessor
Company by issuing subordinated debt and common stock to Azimuth Technologies,
L.P. and to certain directors and executive officers of Anteon. The limited
partners of Azimuth LP include, among others, affiliates of Caxton-Iseman
Capital, Mr. Steven Lefkowitz, Mr. Robert Ferris and a number of business
associates of Caxton-Iseman Capital. The sole general partner of Azimuth LP is
Georgica (Azimuth Technologies), L.P., the sole general partner of which is a
corporation solely owned by Mr. Frederick Iseman. As a result, Mr. Frederick
Iseman controls Azimuth LP, Azimuth and Anteon.

    Since April 1997, Anteon has been party to an arrangement (the
"Caxton-Iseman Capital Arrangement") with Caxton-Iseman Capital, an affiliate of
Anteon. The terms of the Caxton-Iseman Capital Arrangement are that
Caxton-Iseman Capital will monitor and assist the activities of Anteon in
accordance with, and subject to the investment objectives and guidelines
established by Anteon. Under the terms of the Caxton-Iseman Arrangement, Anteon
paid Caxton-Iseman Capital (1) a $500,000 annual fee, payable annually
commencing January 1, 1998, and terminating upon the successful completion of
the acquisition, (2) a fee, paid upon the successful completion of the
acquisition, of $1.15 million and (3) an annual fee, paid upon the successful
completion of the acquisition, equal to 3% of the EBITDA of Anteon. The fees
under clauses (1) and (3) were pro-rated for partial years. Anteon expensed and
paid $400,000 under this arrangement during 1998.

                    DESCRIPTION OF OTHER MATERIAL AGREEMENTS

OGDEN NOTE

    The consideration paid by Azimuth when it acquired our predecessor company
included a note of Azimuth in favor of Ogden Technology Services Corporation
("Ogden"), the parent company of Ogden Professional Services Corporation, in the
principal amount of $8.5 million, of which $3.65 million is outstanding. The
Ogden note is an adjustable, nonnegotiable, subordinated 9% promissory note due
April 22, 2004. Ogden has the right, so long as (1) no defaults under a senior
credit agreement have occurred and (2) Ogden, at its sole cost and expense, has
delivered a written report of an independent third-party appraiser that Azimuth
will be solvent (after giving effect to the guarantee described in this
sentence), to cause Azimuth to execute and deliver to Ogden a guarantee of the
Ogden note; provided that the terms and conditions of such guarantee must be
satisfactory to the senior debt holders in all respects. Such guarantee must be
subject to a subordination agreement acceptable to the senior debt holders, and
must be secured by a subordinated second lien on the collateral under the senior
credit agreement on terms acceptable to the senior debt holders.

    Interest on the Ogden note is due and payable quarterly in arrears. Azimuth
may at any time prepay principal or interest, in whole or in part, without
premium or penalty. Azimuth must prepay in full upon a sale, merger or public
offering of the capital stock of Anteon. The Ogden note is wholly subordinate
and junior in right of payment to Anteon's borrowings under the new credit
facility and any amendments, refinancings or replacements thereof.

EXISTING INTEREST RATE SWAP AGREEMENTS

    We have entered into interest rate swap agreements to reduce the impact of
changes in interest rates under our new credit agreement. At June 30, 1999, we
had outstanding interest rate swap agreements with commercial banks having a
total notional principal amount of $35 million. The interest rate swap
agreements mature as of December 31, 2002, December 31, 2003, and September 25,
2003, respectively. The differential to be paid or received is accrued as
interest rates change and is recognized over the life of the agreements. We
expect to repay all our obligations under these interest rate swap agreements
and terminate them at the same time as the existing credit agreement.

VECTOR DATA CONTINGENT PAYMENTS

    On August 29, 1997, Anteon acquired all of the outstanding stock of Vector
Data, as well as Vector Data's 80% interest in Vector Data Systems (UK) Limited.
The consideration to the former stockholders of Vector Data included up to $6
million in cash to be paid by Anteon contingent upon Vector Data meeting certain
revenue and gross profit thresholds for fiscal years 1998 and 1999. Vector Data
did not meet the revenue and gross profit thresholds for fiscal year 1998, and,
accordingly, a maximum of $3 million only can now potentially become payable.

TECHMATICS DEFERRED AND CONTINGENT PAYMENTS

    On May 29, 1998, Anteon acquired all of the outstanding stock of Techmatics.
Additional consideration of between $3.75 million and $6.25 million may become
due to be paid by Anteon contingent upon Techmatics meeting certain operating
profit thresholds for its fiscal year ending June 30, 1999, to be calculated by
September 30, 1999. However, if Anteon chooses to modify Techmatics' financial
reporting to a calendar year basis, such calculation must be made by April 1,
2000, but interest at a rate of 6% per year will accrue beginning September 30,
1999 and will increase to a rate of 7.5% per year beginning April 1, 2000 on any
amount of contingent consideration subsequently determined to have been earned.

                                       79
<PAGE>
TECHMATICS NOTES

    On May 29, 1998, as part of Anteon's acquisition of Techmatics, Anteon
issued subordinated promissory notes due May 31, 2000 in favor of each of the
then existing stockholders and option holders of Techmatics, in the aggregate
principal amount of $10 million. Under the terms of the Techmatics notes,
one-tenth of the aggregate principal amount, $1 million, was paid as of May 31,
1999, and the remaining nine-tenths of the aggregate principal amount, $9
million, together with interest accruing from May 31, 1999 on four-ninths of the
principal amount then outstanding, $4 million, at a rate of 6% per annum, is due
and payable on May 31, 2000. All overdue amounts of principal will bear interest
at a rate of 7.5% per annum. Anteon is entitled to prepay the Techmatics notes,
in whole or in part, without penalty or premium.

    The Techmatics notes are wholly subordinate and junior in right of payment
to Anteon's borrowings under the new credit facility and any amendments,
refinancings or replacements thereof, and to the Ogden note.

    Anteon will be in default under any particular Techmatics note upon the
occurrence of any of the following events of default: (1) Anteon fails to make
any payment of principal or interest under such Techmatics note when due; (2)
Anteon defaults under its new credit agreement or any amendments, refinancings
or replacements thereof, or under the Ogden note; (3) (a) a consolidation,
merger or similar reorganization in which Anteon's stockholders before the
reorganization own less than 50% of the voting power of the surviving entity
after the reorganization, or (b) any transaction or series of transactions in
which more than 50% of Anteon's voting power is transferred except any public
offering of Anteon's common stock; (4) a sale, lease, transfer or other
disposition in a transaction or series of transactions of all or substantially
all of the assets of Anteon; or (5) Anteon is involved in proceedings relating
to bankruptcy, insolvency, reorganization or relief of debts.

NEW CREDIT FACILITY

    Simultaneous with the completion of the acquisition, Anteon entered into a
new credit facility under a new credit agreement among Anteon, as borrower,
CSFB, as administrative agent and lead arranger, Mellon, as co-arranger,
collateral agent and syndication agent, Deutsche Bank, as documentation agent,
and a syndicate of financial institutions, including CSFB, Deutsche Bank and
Mellon. Pursuant to the terms of the new credit agreement, the lenders, subject
to certain conditions, provide a credit facility of up to $180.0 million to
Anteon consisting of: (1) a $120.0 million six-year senior secured revolving
credit facility with a $10.0 million letter of credit sublimit and (2) a $60.0
million six-year senior secured term loan facility. The Techmatics notes are
also wholly subordinate and junior in right of payment to any refinancings or
replacements of our existing credit facility, including our new credit facility
and the Ogden note. The aggregate amount available for borrowing under the
revolving credit facility is determined based on a portion of eligible accounts
receivable. At June 30, 1999 Anteon had up to $66.4 million of borrowing
availability under the revolving credit facility, subject to Anteon's borrowing
base and ratio of net debt to EBITDA (as defined in the new credit facility), of
which $13.0 million had been drawn. See "Use of Proceeds" included elsewhere in
this prospectus.

    SECURITY AND GUARANTEES

    All existing and future domestic subsidiaries of Anteon unconditionally
guarantee the repayment of the new credit facility. The new credit facility is
secured by substantially all of the tangible and intangible assets of Anteon and
the credit agreement guarantors. All of the capital stock of Anteon and
substantially all of the capital stock of Anteon's subsidiaries, including A&T,
is pledged as part of the security for the new credit facility.

    MATURITY AND AMORTIZATION

    Loans made under the term loan facility will mature on the sixth anniversary
of June 23, 1999, and up to $45 million of the aggregate principal amount under
the new credit facility will amortize ratably on a quarterly basis commencing 24
months after June 23, 1999, with up to $15 million due at final maturity. Loans
made under the revolving credit facility will mature on the sixth anniversary of
June 23, 1999.

    INTEREST

    Borrowings under the new credit facility bear interest at a floating rate
based upon, at the option of Anteon, LIBOR or the base rate, in each case plus a
margin determined based upon Anteon's ratio of net debt to EBITDA (as defined in
the new credit facility). Anteon has also agreed to pay administration fees,
commitment fees and certain expenses and to provide certain indemnities, all of
which Anteon believes are customary for financings of this type.

    PREPAYMENTS

    Anteon is required to prepay, subject to exceptions set forth in the new
credit agreement, borrowings under the term loan facility with (i) 75% of excess
cash flow, (ii) 100% of net cash proceeds of non-ordinary course asset sales or
other dispositions of property by Anteon and its subsidiaries, (iii) 100% of net
cash proceeds of issuances of debt obligations of Anteon and its subsidiaries
and (iv) 50% of net cash proceeds of public issuances of equity securities of
Anteon.

    COVENANTS

    The new credit agreement contains affirmative and negative covenants
customary for such financings. The new credit agreement also contains financial
covenants customary for such financings, including, but not limited to: maximum
ratio of net debt to EBITDA; maximum ratio of senior debt to EBITDA (as defined
in the new credit facility); limitation on capital expenditures; and minimum
EBITDA.

    EVENTS OF DEFAULT

    The new credit agreement contains events of default customary for such
financings, including, but not limited to: nonpayment of principal, interest,
fees or other amounts when due; violation of covenants; failure of any
representation or warranty to be true in all material respects when made or
deemed made; cross default and cross acceleration; change in control; bankruptcy
events; material judgments; ERISA; and actual or Anteon-asserted invalidity of
the guarantees or security documents. Such events of default allow for certain
grace periods.

                               THE EXCHANGE OFFER

TERMS OF THE EXCHANGE OFFER

    We are offering to exchange our exchange notes for a like aggregate
principal amount at maturity of our initial notes.

    The exchange notes that we propose to issue in this exchange offer will be
substantially identical to our initial notes except that, unlike our initial
notes, the exchange notes will have no transfer restrictions or registration
rights. You should read the description of the exchange notes in the section in
this prospectus entitled "Description of the Notes."

    We reserve the right in our sole discretion to purchase or make offers for
any initial notes that remain outstanding following the expiration or
termination of this exchange offer and, to the extent permitted by applicable
law, to purchase initial notes in the open market or privately negotiated
transactions, one or more additional tender or exchange offers or otherwise. The
terms and prices of these purchases or offers could differ significantly from
the terms of this exchange offer. In addition, nothing in this exchange offer
will prevent us from exercising our right to discharge our obligations on the
initial notes by depositing certain securities with the trustee and otherwise.

EXPIRATION DATE; EXTENSIONS; AMENDMENTS; TERMINATION


    This exchange offer will expire at 5:00 p.m., New York City time, on
Tuesday, September 28, 1999, unless we extend it in our reasonable discretion.
The expiration date of this exchange offer will be at least 20 business days
after the commencement of the exchange offer in accordance with Rule 14e-1(a)
under the Securities Exchange Act of 1934.


    We expressly reserve the right to delay acceptance of any initial notes,
extend or terminate this exchange offer and not accept any initial notes that we
have not previously accepted if any of the conditions described below under
"--Conditions to the Exchange Offer" have not been satisfied or waived by us. We
will notify the exchange agent of any extension by oral notice promptly
confirmed in writing or by written notice. We will also notify the holders of
the initial notes by mailing an announcement or by a press release or other
public announcement communicated before 9:00 a.m., New York City time, on the
next business day after the previously scheduled expiration date unless
applicable laws require us to do otherwise.

    We also expressly reserve the right to amend the terms of this exchange
offer in any manner. If we make any material change, we will promptly disclose
this change in a manner reasonably calculated to inform the holders of our
initial notes of the change including providing public announcement or giving
oral or written notice to these holders. A material change in the terms of this
exchange offer could include a change in the timing of the exchange offer, a
change in the exchange agent and other similar changes in the terms of this
exchange offer. If we make any material change to this exchange offer, we will
disclose this change by means of a post-effective amendment to the registration
statement which includes this prospectus and will distribute an amended or
supplemented prospectus to each registered holder of initial notes. In addition,
we will extend this exchange offer for an additional five to ten business days
as required by the Exchange Act, depending on the significance of the amendment,
if the exchange offer would otherwise expire during that period. We will
promptly notify the exchange agent by oral notice, promptly confirmed in
writing, or written notice of any delay in acceptance, extension, termination or
amendment of this exchange offer.

PROCEDURES FOR TENDERING INITIAL NOTES

PROPER EXECUTION AND DELIVERY OF LETTERS OF TRANSMITTAL

    To tender your initial notes in this exchange offer, you must use one of the
six alternative procedures described below:

        (1) REGULAR DELIVERY PROCEDURE: Complete, sign and date the letter of
    transmittal, or a facsimile of the letter of transmittal. Have the
    signatures on the letter of transmittal guaranteed if required by the letter
    of transmittal. Mail or otherwise deliver the letter of transmittal or the
    facsimile together with the certificates representing the initial notes
    being tendered and any other required documents to the exchange agent on or
    before 5:00 p.m., New York City time, on the expiration date.

        (2) BOOK-ENTRY DELIVERY PROCEDURE: Send a timely confirmation of a
    book-entry transfer of your initial notes, if this procedure is available,
    into the exchange agent's account at The Depository Trust Company in
    accordance with the procedures for book-entry transfer described under
    "--Book-Entry Delivery Procedure" below, on or before 5:00 p.m., New York
    City time, on the expiration date.

        (3) GUARANTEED DELIVERY PROCEDURE: If time will not permit you to
    complete your tender by using the procedures described in (1) or (2) above
    before the expiration date, comply with the guaranteed delivery procedures
    described under "--Guaranteed Delivery Procedure" below.

    The method of delivery of the initial notes, the letter of transmittal and
all other required documents is at your election and risk. Instead of delivery
by mail, we recommend that you use an overnight or hand-delivery service. If you
choose the mail, we recommend that you use registered mail, properly insured,
with return receipt requested. IN ALL CASES, YOU SHOULD ALLOW SUFFICIENT TIME TO
ASSURE TIMELY DELIVERY. You should not send any letters of transmittal or
initial notes to us. You must deliver all documents to the exchange agent at its
address provided below. You may also request your broker, dealer, commercial
bank, trust company or nominee to tender your initial notes on your behalf.

    Only a holder of initial notes may tender initial notes in this exchange
offer. A holder is any person in whose name initial notes are registered on our
books or any other person who has obtained a properly completed bond power from
the registered holder.

    If you are the beneficial owner of initial notes that are registered in the
name of a broker, dealer, commercial bank, trust company or other nominee and
you wish to tender your notes, you must contact that registered holder promptly
and instruct that registered holder to tender your notes on your behalf. If you
wish to tender your initial notes on your own behalf, you must, before
completing and executing the letter of transmittal and delivering your initial
notes, either make appropriate arrangements to register the ownership of these
notes in your name or obtain a properly completed bond power from the registered
holder. The transfer of registered ownership may take considerable time.

    You must have any signatures on a letter of transmittal or a notice of
withdrawal guaranteed by:

        (1) a member firm of a registered national securities exchange or of the
    National Association of Securities Dealers, Inc.,

        (2) a commercial bank or trust company having an office or correspondent
    in the United States, or

        (3) an eligible guarantor institution within the meaning of Rule 17Ad-15
    under the Exchange Act,

    UNLESS the initial notes are tendered:

        (1) by a registered holder or by a participant in The Depository Trust
    Company whose name appears on a security position listing as the owner, who
    has not completed the box entitled "Special Issuance Instructions" or
    "Special Delivery Instructions" on the letter of transmittal and only if the

                                       83
<PAGE>
    exchange notes are being issued directly to this registered holder or
    deposited into this participant's account at The Depository Trust Company,
    or

        (2) for the account of a member firm of a registered national securities
    exchange or of the National Association of Securities Dealers, Inc., a
    commercial bank or trust company having an office or correspondent in the
    United States or an eligible guarantor institution within the meaning of
    Rule 17Ad-15 under the Securities Exchange Act of 1934.

    If the letter of transmittal or any bond powers are signed by:

        (1) The recordholder(s) of the initial notes tendered: the signature
    must correspond with the name(s) written on the face of the initial notes
    without alteration, enlargement or any change whatsoever.

        (2) A participant in The Depository Trust Company: the signature must
    correspond with the name as it appears on the security position listing as
    the holder of the initial notes.

        (3) A person other than the registered holder of any initial notes:
    these initial notes must be endorsed or accompanied by bond powers and a
    proxy that authorize this person to tender the initial notes on behalf of
    the registered holder, in satisfactory form to us as determined in our sole
    discretion, in each case, as the name of the registered holder or holders
    appears on the initial notes.

        (4) Trustees, executors, administrators, guardians, attorneys-in-fact,
    officers of corporations or others acting in a fiduciary or representative
    capacity: these persons should so indicate when signing. Unless waived by
    us, evidence satisfactory to us of their authority to so act must also be
    submitted with the letter of transmittal.

BOOK-ENTRY DELIVERY PROCEDURE

    Any financial institution that is a participant in The Depository Trust
Company's systems may make book-entry deliveries of initial notes by causing The
Depository Trust Company to transfer these initial notes into the exchange
agent's account at The Depository Trust Company in accordance with The
Depository Trust Company's procedures for transfer. To effectively tender notes
through The Depository Trust Company, the financial institution that is a
participant in The Depository Trust Company will electronically transmit its
acceptance through the Automatic Tender Offer Program. The Depository Trust
Company will then edit and verify the acceptance and send an agent's message to
the exchange agent for its acceptance. An agent's message is a message
transmitted by The Depository Trust Company to the exchange agent stating that
The Depository Trust Company has received an express acknowledgment from the
participant in The Depository Trust Company tendering the notes that this
participation has received and agrees to be bound by the terms of the letter of
transmittal, and that we may enforce this agreement against this participant.
The exchange agent will make a request to establish an account for the initial
notes at The Depository Trust Company for purposes of the exchange offer within
two business days after the date of this prospectus.

    A delivery of initial notes through a book-entry transfer into the exchange
agent's account at The Depository Trust Company will only be effective if an
agent's message or the letter of transmittal or a facsimile of the letter of
transmittal with any required signature guarantees and any other required
documents is transmitted to and received by the exchange agent at the address
indicated below under "--Exchange Agent" on or before the expiration date unless
the guaranteed delivery procedures described below are complied with. DELIVERY
OF DOCUMENTS TO THE DEPOSITORY TRUST COMPANY DOES NOT CONSTITUTE DELIVERY TO THE
EXCHANGE AGENT.

                                       84
<PAGE>
GUARANTEED DELIVERY PROCEDURE

    If you are a registered holder of initial notes and desire to tender your
notes, and (1) these notes are not immediately available, (2) time will not
permit your notes or other required documents to reach the exchange agent before
the expiration date or (3) the procedures for book-entry transfer cannot be
completed on a timely basis and an agent's message delivered, you may still
tender in this exchange offer if:

        (1) you tender through a member firm of a registered national securities
    exchange or of the National Association of Securities Dealers, Inc., a
    commercial bank or trust company having an office or correspondent in the
    United States, or an eligible guarantor institution within the meaning of
    Rule 17Ad-15 under the Exchange Act,

        (2) on or before the expiration date, the exchange agent receives a
    properly completed and duly executed letter of transmittal or facsimile of
    the letter of transmittal, and a notice of guaranteed delivery,
    substantially in the form provided by us, with your name and address as
    holder of the initial notes and the amount of notes tendered, stating that
    the tender is being made by that letter and notice and guaranteeing that
    within five business days after the expiration date the certificates for all
    the initial notes tendered, in proper form for transfer, or a book-entry
    confirmation with an agent's message, as the case may be, and any other
    documents required by the letter of transmittal will be deposited by the
    eligible institution with the exchange agent, and

        (3) the certificates for all your tendered initial notes in proper form
    for transfer or a book-entry confirmation as the case may be, and all other
    documents required by the letter of transmittal are received by the exchange
    agent within five business days after the expiration date.

ACCEPTANCE OF INITIAL NOTES FOR EXCHANGE; DELIVERY OF EXCHANGE NOTES

    Your tender of initial notes will constitute an agreement between you and us
governed by the terms and conditions provided in this prospectus and in the
related letter of transmittal.

    We will be deemed to have received your tender as of the date when your duly
signed letter of transmittal accompanied by your initial notes tendered, or a
timely confirmation of a book-entry transfer of these notes into the exchange
agent's account at The Depository Trust Company with an agent's message, or a
notice of guaranteed delivery from an eligible institution is received by the
exchange agent.

    All questions as to the validity, form, eligibility, including time of
receipt, acceptance and withdrawal of tenders will be determined by us in our
sole discretion. Our determination will be final and binding.

    We reserve the absolute right to reject any and all initial notes not
properly tendered or any initial notes which, if accepted, would, in our opinion
or our counsel's opinion, be unlawful. We also reserve the absolute right to
waive any conditions of this exchange offer or irregularities or defects in
tender as to particular notes. Our interpretation of the terms and conditions of
this exchange offer, including the instructions in the letter of transmittal,
will be final and binding on all parties. Unless waived, any defects or
irregularities in connection with tenders of initial notes must be cured within
such time as we shall determine. We, the exchange agent or any other person will
be under no duty to give notification of defects or irregularities with respect
to tenders of initial notes. We and the exchange agent or any other person will
incur no liability for any failure to give notification of these defects or
irregularities. Tenders of initial notes will not be deemed to have been made
until such irregularities have been cured or waived. The exchange agent will
return without cost to their holders any initial notes that are not properly
tendered and as to which the defects or irregularities have not been cured or
waived as promptly as practicable following the expiration date.

    If all the conditions to the exchange offer are satisfied or waived on the
expiration date, we will accept all initial notes properly tendered and will
issue the exchange notes promptly thereafter. Please refer to the section of
this prospectus entitled "--Conditions to the Exchange Offer" below. For
purposes of this

                                       85
<PAGE>
exchange offer, initial notes will be deemed to have been accepted as validly
tendered for exchange when, as and if we give oral or written notice of
acceptance to the exchange agent.

    We will issue the exchange notes in exchange for the initial notes tendered
pursuant to a notice of guaranteed delivery by an eligible institution only
against delivery to the exchange agent of the letter of transmittal, the
tendered initial notes and any other required documents, or the receipt by the
exchange agent of a timely confirmation of a book-entry transfer of initial
notes into the exchange agent's account at The Depository Trust Company with an
agent's message, in each case, in form satisfactory to us and the exchange
agent.

    If any tendered initial notes are not accepted for any reason provided by
the terms and conditions of this exchange offer or if initial notes are
submitted for a greater principal amount than the holder desires to exchange,
the unaccepted or non-exchanged initial notes will be returned without expense
to the tendering holder, or, in the case of initial notes tendered by book-entry
transfer procedures described above, will be credited to an account maintained
with the book-entry transfer facility, as promptly as practicable after
withdrawal, rejection of tender or the expiration or termination of the exchange
offer.

    By tendering into this exchange offer, you will irrevocably appoint our
designees as your attorney-in-fact and proxy with full power of substitution and
resubstitution to the full extent of your rights on the notes tendered. This
proxy will be considered coupled with an interest in the tendered notes. This
appointment will be effective only when, and to the extent that we accept your
notes in this exchange offer. All prior proxies on these notes will then be
revoked and you will not be entitled to give any subsequent proxy. Any proxy
that you may give subsequently will not be deemed effective. Our designees will
be empowered to exercise all voting and other rights of the holders as they may
deem proper at any meeting of note holders or otherwise. The initial notes will
be validly tendered only if we are able to exercise full voting rights on the
notes, including voting at any meeting of the note holders, and full rights to
consent to any action taken by the note holders.

WITHDRAWAL OF TENDERS

    Except as otherwise provided in this prospectus, you may withdraw tenders of
initial notes at any time before 5:00 p.m., New York City time, on the
expiration date.

    For a withdrawal to be effective, you must send a written or facsimile
transmission notice of withdrawal to the exchange agent before 5:00 p.m., New
York City time, on the expiration date at the address provided below under
"--Exchange Agent" and before acceptance of your tendered notes for exchange by
us.

    Any notice of withdrawal must:

        (1) specify the name of the person having tendered the initial notes to
    be withdrawn,

        (2) identify the notes to be withdrawn, including, if applicable, the
    registration number or numbers and total principal amount of these notes,

        (3) be signed by the person having tendered the initial notes to be
    withdrawn in the same manner as the original signature on the letter of
    transmittal by which these notes were tendered, including any required
    signature guarantees, or be accompanied by documents of transfer sufficient
    to permit the trustee for the initial notes to register the transfer of
    these notes into the name of the person having made the original tender and
    withdrawing the tender,

        (4) specify the name in which any of these initial notes are to be
    registered, if this name is different from that of the person having
    tendered the initial notes to be withdrawn, and

                                       86
<PAGE>
        (5) if applicable because the initial notes have been tendered though
    the book-entry procedure, specify the name and number of the participant's
    account at The Depository Trust Company to be credited, if different than
    that of the person having tendered the initial notes to be withdrawn.

    We will determine all questions as to the validity, form and eligibility,
including time of receipt, of all notices of withdrawal and our determination
will be final and binding on all parties. Initial notes that are withdrawn will
be deemed not to have been validly tendered for exchange in this exchange offer.

    The exchange agent will return without cost to their holders all initial
notes that have been tendered for exchange and are not exchanged for any reason,
as promptly as practicable after withdrawal, rejection of tender or expiration
or termination of this exchange offer.

    You may retender properly withdrawn initial notes in this exchange offer by
following one of the procedures described under "--Procedures for Tendering
Initial Notes" above at any time on or before the expiration date.

YOUR FAILURE TO PARTICIPATE IN THE EXCHANGE OFFER WILL HAVE ADVERSE CONSEQUENCES

    The initial notes were not registered under the Securities Act or under the
securities laws of any state and you may not resell them, offer them for resale
or otherwise transfer them unless they are subsequently registered or resold
under an exemption from the registration requirements of the Securities Act and
applicable state securities laws. If you do not exchange your initial notes for
exchange notes in accordance with this exchange offer, or if you do not properly
tender your initial notes in this exchange offer, you will not be able to
resell, offer to resell or otherwise transfer the initial notes unless they are
registered under the Securities Act or unless you resell them, offer to resell
or otherwise transfer them under an exemption from the registration requirements
of, or in a transaction not subject to, the Securities Act. In addition, you
will not necessarily be able to obligate us to register the initial notes under
the Securities Act.

                            DESCRIPTION OF THE NOTES

    Anteon Corporation issued the notes under an indenture dated as of May 11,
1999 between itself and IBJ Whitehall Bank & Trust Company, as trustee (the
"Trustee"), a copy of which is filed as an exhibit to the registration statement
relating to this exchange offer. The terms of the notes include those stated in
the indenture and those made part of the indenture by reference to the Trust
Indenture Act of 1939.

    Some terms used in this description are defined under the subheading
"--Certain Definitions". In this description, the word "Company" refers only to
Anteon Corporation and not to any of its subsidiaries.

    The following description is only a summary of the material provisions of
the indenture. We urge you to read the indenture because it, not this
description, defines your rights as holders of these notes. You may request
copies of the these agreements at our address set forth under the heading "Where
You Can Find More Information".

BRIEF DESCRIPTION OF THE NOTES

    These notes:

    - are unsecured senior subordinated obligations of the Company;

    - are subordinated in right of payment to all existing and future Senior
      Indebtedness of the Company;

    - are senior in right of payment to any future Subordinated Obligations of
      the Company; and

    - are subject to registration with the SEC pursuant to the Registration
      Rights Agreement.

PRINCIPAL, MATURITY AND INTEREST

    The Company issued the notes initially in the principal amount of $100
million. The Company will issue the notes in denominations of $1,000 and any
integral multiple of $1,000. The notes mature on May 15, 2009. Subject to our
compliance with the covenant described under the subheading "--Certain
Covenants--Limitation on Indebtedness", we are permitted to issue more notes
under the indenture in an unlimited principal amount. Any such additional notes
that are actually issued will be treated as issued and outstanding notes for all
purposes of the indenture and this "Description of the Notes" unless the context
indicates otherwise.

    Interest on these notes will accrue at the rate of 12% per annum and will be
payable semiannually in arrears on May 15 and November 15, commencing on
November 15, 1999. We will make each interest payment to the holders of record
of these notes on the immediately preceding May 1 and November 1. We will pay
interest on overdue principal at 1% per annum in excess of the above rate and
will pay interest on overdue installments of interest at such higher rate to the
extent lawful.

    Interest on these notes will accrue from the date of original issuance or,
if interest has already been paid, from the date it was most recently paid.
Interest will be computed on the basis of a 360-day year comprised of twelve
30-day months.

OPTIONAL REDEMPTION

    Except as set forth below, we will not be entitled to redeem the notes at
our option prior to May 15, 2004.

    On and after May 15, 2004, we will be entitled at our option to redeem all
or a portion of these notes upon not less than 30 nor more than 60 days' notice,
at the redemption prices (expressed in percentages of principal amount on the
redemption date), plus accrued interest to the redemption date (subject to the
right of holders of record on the relevant record date to receive interest due
on the relevant interest

                                       90

the years set forth below:

</TABLE>

    In addition, before May 15, 2002, we may at our option on one or more
occasions redeem notes (which includes additional notes, if any) in an aggregate
principal amount not to exceed 25% of the aggregate principal amount of the
notes (which includes additional notes, if any) originally issued at a
redemption price (expressed as a percentage of principal amount of 112%, plus
accrued and unpaid interest to the redemption date, with the net cash proceeds
from one or more Public Equity Offerings following which there is a Public
Market (PROVIDED that, if the Public Equity Offering is an offering by Parent, a
portion of the Net Cash Proceeds thereof equal to the amount required to redeem
any such notes is contributed to the equity capital of the Company); PROVIDED
that

    (1) at least 75% of such aggregate principal amount of notes (which includes
       additional notes, if any) remains outstanding immediately after the
       occurrence of each such redemption (other than notes held, directly or
       indirectly, by the Company or its Affiliates); and

    (2) each such redemption occurs within 60 days after the date of the related
       Public Equity Offering.

SELECTION AND NOTICE OF REDEMPTION

    If we are redeeming less than all the notes at any time, the Trustee will
select notes on a PRO RATA basis, by lot or by such other method as the Trustee
in its sole discretion shall deem to be fair and appropriate.

    We will redeem notes of $1,000 or less in whole and not in part. We will
cause notices of redemption to be mailed by first-class mail at least 30 but not
more than 60 days before the redemption date to each holder of notes to be
redeemed at its registered address.

    If any note is to be redeemed in part only, the notice of redemption that
relates to that note shall state the portion of the principal amount thereof to
be redeemed. We will issue a new note in principal amount equal to the
unredeemed portion of the original note in the name of the holder thereof upon
cancelation of the original note. Notes called for redemption become due on the
date fixed for redemption. On and after the redemption date, interest ceases to
accrue on notes or portions of them called for redemption.

MANDATORY REDEMPTION; OFFERS TO PURCHASE; OPEN MARKET PURCHASES

    Subject to the terms described above, we are not required to make any
mandatory redemption or sinking fund payments with respect to the notes.
However, under certain circumstances, we may be required to offer to purchase
the notes as described under the captions "--Change of Control" and "Certain
Covenants--Limitation on Sales of Assets and Subsidiary Stock". We may at any
time and from time to time purchase notes in the open market or otherwise.

SUBSIDIARY GUARANTIES

    The Subsidiary Guarantors will jointly and severally guarantee, on a senior
subordinated basis, our obligations under these notes. The obligations of each
Subsidiary Guarantor under its Subsidiary Guaranty will be limited as necessary
to prevent that Subsidiary Guaranty from constituting a fraudulent conveyance
under applicable law. See "Risk Factors--Subordination".

                                       91
<PAGE>
    Each Subsidiary Guarantor that makes a payment under its Subsidiary Guaranty
will be entitled to a contribution from each other Subsidiary Guarantor in an
amount equal to such other Subsidiary Guarantor's PRO RATA portion of such
payment based on the respective net assets of all the Subsidiary Guarantors at
the time of such payment determined in accordance with GAAP.

    If a Subsidiary Guaranty were rendered voidable, it could be subordinated by
a court to all other indebtedness (including guarantees and other contingent
liabilities) of the applicable Subsidiary Guarantor, and, depending on the
amount of such indebtedness, a Subsidiary Guarantor's liability on its
Subsidiary Guaranty could be reduced to zero. See "Risk Factors--Subordination".

    The Subsidiary Guaranty of a Subsidiary Guarantor will be released:

    (1) upon the sale or other disposition (including by way of consolidation or
       merger) of a Subsidiary Guarantor;

    (2) upon the sale or disposition of all or substantially all the assets of a
       Subsidiary Guarantor; or

    (3) the designation of such Subsidiary Guarantor as an Unrestricted
       Subsidiary pursuant to the terms of the indenture;

in the case of (1) and (2) above, other than to the Company or an Affiliate of
the Company and as permitted by the indenture.

RANKING

SENIOR INDEBTEDNESS VERSUS NOTES

    The payment of the principal of, premium, if any, and interest on the notes
and the payment of any Subsidiary Guaranty will be subordinate in right of
payment to the prior payment in full in cash of all Senior Indebtedness of the
Company or the relevant Subsidiary Guarantor, as the case may be, including the
obligations of the Company and such Subsidiary Guarantor under the Credit
Agreement.

    As of December 31, 1998, after giving pro forma effect to the Transactions:

    (1) the Company's Senior Indebtedness would have been approximately $78.9
       million, all of which was secured indebtedness; and

    (2) the Senior Indebtedness of the Subsidiary Guarantors would have been
       approximately $78.9 million. Substantially all of the pro forma Senior
       Indebtedness of the Subsidiary Guarantors comprises their respective
       guaranties of Senior Indebtedness of the Company under the Credit
       Agreement.

    Although the indenture contains limitations on the amount of additional
Indebtedness that the Company and the Subsidiary Guarantors may incur, under
certain circumstances the amount of such Indebtedness could be substantial and,
in any case, such Indebtedness may be Senior Indebtedness. See "--Certain
Covenants--Limitation on Indebtedness".

LIABILITIES OF SUBSIDIARIES VERSUS NOTES

    A substantial portion of our operations are conducted through our
subsidiaries. Some of our subsidiaries are not guaranteeing the notes. Claims of
creditors of such non-guarantor subsidiaries, including trade creditors holding
indebtedness or guarantees issued by such non-guarantor subsidiaries, and claims
of preferred stockholders of such non-guarantor subsidiaries generally will have
priority with respect to the assets and earnings of such non-guarantor
subsidiaries over the claims of our creditors, including holders of the notes,
even if such claims do not constitute Senior Indebtedness. Accordingly, the
notes and each Subsidiary Guaranty will be effectively subordinated to creditors
(including trade creditors) and preferred stockholders, if any, of such
non-guarantor subsidiaries.

                                       92
<PAGE>
    At March 31, 1999, after giving pro forma effect to the Transactions, the
total liabilities of our subsidiaries (other than the Subsidiary Guarantors)
would have been approximately $0.9 million, including trade payables. Although
the indenture limits the incurrence of Indebtedness and preferred stock of
certain of our subsidiaries, such limitation is subject to a number of
significant qualifications. Moreover, the indenture does not impose any
limitation on the incurrence by such subsidiaries of liabilities or obligations
that are not considered Indebtedness under the indenture. See "--Certain
Covenants-- Limitation on Indebtedness".

OTHER SENIOR SUBORDINATED INDEBTEDNESS VERSUS NOTES

    Only Indebtedness of the Company or a Subsidiary Guarantor that is Senior
Indebtedness will rank senior to the notes and the relevant Subsidiary Guaranty
in accordance with the provisions of the indenture. The notes and each
Subsidiary Guaranty will in all respects rank PARI PASSU with all other Senior
Subordinated Indebtedness of the Company and the relevant Subsidiary Guarantor,
respectively.

    We have agreed in the indenture that we will not Incur, directly or
indirectly, any indebtedness that is contractually subordinate or junior in
right of payment to our senior Indebtedness, unless such indebtedness is Senior
Subordinated Indebtedness or is expressly subordinated in right of payment to
senior Subordinated Indebtedness. The indenture does not treat unsecured
Indebtedness as subordinated or junior to Secured Indebtedness merely because it
is unsecured.

PAYMENT OF NOTES

    We are not permitted to pay principal of, premium, if any, or interest on
the notes or make any deposit pursuant to the provisions described under
"--Defeasance" below and may not repurchase, redeem or otherwise retire any
notes (collectively, "pay the notes") if:

    (1) any Designated Senior Indebtedness is not paid when due; or

    (2) any other default on designated Senior Indebtedness occurs and the
       maturity of such designated Senior Indebtedness is accelerated in
       accordance with its terms;

unless, in either case, the default has been cured or waived and any such
acceleration has been rescinded or such Designated Senior Indebtedness has been
paid in full in cash. Regardless of the foregoing, we are permitted to pay the
notes if we and the Trustee receive written notice approving such payment from
the Representative of any Designated Senior Indebtedness with respect to which
either of the events set forth in clause (1) or (2) above has occurred and is
continuing.

    During the continuance of any default (other than a default described in
clause (1) or (2) above) with respect to any Designated Senior Indebtedness
pursuant to which the maturity thereof may be accelerated without further notice
(except such notice as may be required to effect such acceleration) or the
expiration of any applicable grace periods, we are not permitted to pay the
notes for a period (a "Payment Blockage Period") commencing upon the receipt by
the Trustee (with a copy to us) of written notice (a "Blockage Notice") of such
default from the Representative of the holders of such Designated Senior
Indebtedness specifying an election to effect a Payment Blockage Period and
ending 179 days thereafter. The Payment Blockage Period will end earlier if such
Payment Blockage Period is terminated:

    (1) by written notice to the Trustee and us from the Person or Persons who
       gave such Blockage Notice;

    (2) because no defaults continue in existence which would permit the
       acceleration of the maturity of any designated Senior Indebtedness at
       such time; or

    (3) because such Designated Senior Indebtedness has been discharged or
       repaid in full in cash.

                                       93
<PAGE>
    Notwithstanding the provisions described above, unless the holders of such
Designated Senior Indebtedness or the Representative of such holders have
accelerated the maturity of such Designated Senior Indebtedness, or any payment
default described in clause (1) or (2) of the second preceding paragraph exists,
we are permitted to resume paying the notes after the end of such Payment
Blockage Period. The notes shall not be subject to more than one Payment
Blockage Period in any consecutive 360-day period, irrespective of the number of
defaults with respect to Designated Senior Indebtedness during such period,
except that if any Blockage Notice is delivered to the Trustee by or on behalf
of holders of Designated Senior Indebtedness (other than holders of the Bank
Indebtedness), a Representative of holders of Bank Indebtedness may give another
Blockage Notice within such period. However, in no event may the total number of
days during which any Payment Blockage Period or Periods is in effect exceed 179
days in the aggregate during any 360 consecutive day period, and there must be
181 days during any 360-day consecutive period during which no Payment Blockage
Period is in effect.

    Upon any payment or distribution of the assets of the Company upon any
liquidation or dissolution or reorganization of or similar proceeding relating
to the Company or its property:

    (1) the holders of Senior Indebtedness will be entitled to receive payment
       in full in cash of all Obligations with respect to such Senior
       Indebtedness before the holders of the notes are entitled to receive any
       payment;

    (2) until all Obligations with respect to Senior Indebtedness are paid in
       full in cash, any payment or distribution to which holders of the notes
       would be entitled but for the subordination provisions of the indenture
       will be made to holders of such Senior Indebtedness as their interests
       may appear, except that holders of notes may receive certain Capital
       Stock and subordinated debt obligations; and

    (3) if a distribution is made to holders of the notes that, due to the
       subordination provisions, should not have been made to them, such holders
       of the notes are required to hold it in trust for the holders of Senior
       Indebtedness and pay it over to them as their interests may appear.

    If payment of the notes is accelerated because of an Event of Default, the
Company or the Trustee must promptly notify the holders of Designated Senior
Indebtedness or the Representative of such holders of the acceleration. If any
Designated Senior Indebtedness is outstanding, neither the Company nor any
Subsidiary Guarantor may pay the notes until five Business Days after the
Representatives of all the issues of Designated Senior Indebtedness receive
notice of such acceleration and, thereafter, may pay the notes only if the
indenture otherwise permits payment at that time.

    A Subsidiary Guarantor's obligations under its Subsidiary Guaranty are
senior subordinated obligations. As such, the rights of Noteholders to receive
payment by a Subsidiary Guarantor pursuant to its Subsidiary Guaranty will be
subordinated in right of payment to the rights of holders of Senior Indebtedness
of such Subsidiary Guarantor. The terms of the subordination provisions
described above with respect to the Company's obligations under the notes apply
equally to a Subsidiary Guarantor and the obligations of such Subsidiary
Guarantor under its Subsidiary Guaranty.

    By reason of the subordination provisions contained in the indenture, in the
event of a liquidation or insolvency proceeding, creditors of the Company or a
Subsidiary Guarantor who are holders of Senior Indebtedness of the Company or a
Subsidiary Guarantor, as the case may be, may recover more, ratably, than the
holders of the notes, and creditors of ours who are not holders of Senior
Indebtedness may recover less, ratably, than holders of Senior Indebtedness and
may recover more, ratably, than the holders of the notes.

    The terms of the subordination provisions described above will not apply to
payments from money or the proceeds of U.S. Government Obligations held in trust
by the Trustee for the payment of principal of and interest on the Notes
pursuant to the provisions described under "--Defeasance", if the foregoing
subordination provisions were not violated at the time the respective amounts
were deposited pursuant to such defeasance provisions.

CHANGE OF CONTROL

    Upon the occurrence of any of the following events (each a "Change of
Control"), each Holder shall have the right to require that the Company
repurchase such Holder's notes at a purchase price in cash equal to 101% of the
principal amount thereof on the date of purchase plus accrued and unpaid
interest, if any, to the date of purchase (subject to the right of holders of
record on the relevant record date to receive interest due on the relevant
interest payment date):

    (1) prior to the earlier to occur of (A) the first public offering of common
       stock of Parent or (B) the first public offering of common stock of the
       Company, the Permitted Holders cease to be the "beneficial owner" (as
       defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or
       indirectly, of a majority in the aggregate of the total voting power of
       the Voting Stock of the Company, whether as a result of issuance of
       securities of the Parent or the Company, any merger, consolidation,
       liquidation or dissolution of the Parent or the Company, any direct or
       indirect transfer of securities by Parent or otherwise (for purposes of
       this clause (1) and clause (2) below, the Permitted Holders shall be
       deemed to beneficially own any Voting Stock of a corporation (the
       "specified corporation") held by any other corporation (the "parent
       corporation") so long as the Permitted Holders beneficially own (as so
       defined), directly or indirectly, in the aggregate a majority of the
       voting power of the Voting Stock of the parent corporation);

    (2) any "person" (as such term is used in Sections 13(d) and 14(d) of the
       Exchange Act), other than one or more Permitted Holders, is or becomes
       the beneficial owner (as defined in clause (1) above, except that for
       purposes of this clause (2) such person shall be deemed to have
       "beneficial ownership" of all shares that any such person has the right
       to acquire, whether such right is exercisable immediately or only after
       the passage of time), directly or indirectly, of more than 35% of the
       total voting power of the Voting Stock of the Company; PROVIDED, HOWEVER,
       that the Permitted Holders beneficially own (as defined in clause (1)
       above), directly or indirectly, in the aggregate a lesser percentage of
       the total voting power of the Voting Stock of the Company than such other
       person and do not have the right or ability by voting power, contract or
       otherwise to elect or designate for election a majority of the Board of
       Directors (for the purposes of this clause (2), such other person shall
       be deemed to beneficially own any Voting Stock of a specified corporation
       held by a parent corporation, if such other person is the beneficial
       owner (as defined in this clause (2)), directly or indirectly, of more
       than 35% of the voting power of the Voting Stock of such parent
       corporation and the Permitted Holders beneficially own (as defined in
       clause (1) above), directly or indirectly, in the aggregate a lesser
       percentage of the voting power of the Voting Stock of such parent
       corporation and do not have the right or ability by voting power,
       contract or otherwise to elect or designate for election a majority of
       the board of directors of such parent corporation);

    (3) individuals who on the Issue Date constituted the Board of Directors
       (together with any new directors whose election by such Board of
       Directors or whose nomination for election by the shareholders of the
       Company was approved by a vote of 66 2/3% of the directors of the Company
       then still in office who were either directors on the Issue Date or whose
       election or nomination for election was previously so approved) cease for
       any reason to constitute a majority of the Board of Directors then in
       office;

    (4) the merger or consolidation of the Company with or into another Person
       or the merger of another Person with or into the Company, or the sale of
       all or substantially all the assets of the Company to another Person
       (other than a Person that is controlled by the Permitted Holders), and,
       in the case of any such merger or consolidation, the securities of the
       Company that are outstanding immediately prior to such transaction and
       which represent 100% of the aggregate voting power of the Voting Stock of
       the Company are changed into or exchanged for cash, securities or
       property, unless pursuant to such transaction such securities are changed
       into or

                                       95
<PAGE>
       exchanged for, in addition to any other consideration, securities of the
       surviving corporation that represent immediately after such transaction,
       at least a majority of the aggregate voting power of the Voting Stock of
       the surviving corporation.

    Within 30 days following any Change of Control, we will mail a notice to
each Holder with a copy to the Trustee (the "Change of Control Offer") stating:

    (1) that a Change of Control has occurred and that such Holder has the right
       to require us to purchase such Holder's notes at a purchase price in cash
       equal to 101% of the principal amount thereof on the date of purchase,
       plus accrued and unpaid interest, if any, to the date of purchase
       (subject to the right of Holders of record on the relevant record date to
       receive interest on the relevant interest payment date);

    (2) the circumstances and relevant facts regarding such Change of Control
       (including information with respect to pro forma historical income, cash
       flow and capitalization after giving effect to such Change of Control);

    (3) the repurchase date (which shall be no earlier than 30 days nor later
       than 60 days from the date such notice is mailed); and

    (4) the instructions, as determined by us, consistent with the covenant
       described hereunder, that a Holder must follow in order to have its Notes
       purchased.

    If the terms of the Credit Agreement prohibit the Company from making a
Change of Control Offer or from purchasing any notes pursuant thereto, prior to
the mailing of the notice to Holders described in the preceding paragraph, but
in any event within 30 days following any Change of Control, the Company
covenants to:

    (1) repay in full any indebtedness outstanding under the Credit Agreement or
        offer to repay in full all such indebtedness and repay the Indebtedness
        of each lender which has accepted such offer; or

    (2) obtain the requisite consent under the Credit Agreement to permit the
        purchase of the Notes as described above.

    The Company must first comply with the covenant described above before it
will be required to purchase notes in the event of a Change of Control;
PROVIDED, HOWEVER, that the Company's failure to comply with the covenant
described in the preceding sentence or to make a Change of Control offer because
of any such failure shall constitute a Default described in clause (4) under
"--Defaults" below (and not under clause (2) thereof). As a result of the
foregoing, a holder of the Notes may not be able to compel the Company to
purchase the notes unless the Company is able at the time to refinance all of
the Indebtedness outstanding under the Credit Agreement or obtain requisite
consents under the Credit Agreement.

    We will not be required to make a Change of Control Offer following a Change
of Control Offer if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements set forth
in the indenture applicable to a Change of Control Offer made by us and
purchases all notes validly tendered and not withdrawn under such Change of
Control Offer.

    We will comply, to the extent applicable, with the requirements of Section
14(e) of the Exchange Act and any other securities laws or regulations in
connection with the repurchase of notes as a result of a Change of Control. To
the extent that the provisions of any securities laws or regulations conflict
with the provisions of the covenant described hereunder, we will comply with the
applicable securities laws and regulations and shall not be deemed to have
breached our obligations under the covenant described hereunder by virtue
thereof.

                                       96
<PAGE>
    The Change of Control purchase feature of the notes may in certain
circumstances make more difficult or discourage a sale or takeover of the
Company and, thus, the removal of incumbent management. The Change of Control
purchase feature is a result of negotiations between the Company and the Initial
Purchasers. We have no present intention to engage in a transaction involving a
Change of Control, although it is possible that we could decide to do so in the
future. Subject to the limitations discussed below, we could, in the future,
enter into certain transactions, including acquisitions, refinancings or other
recapitalizations, that would not constitute a Change of Control under the
indenture, but that could increase the amount of indebtedness outstanding at
such time or otherwise affect our capital structure or credit ratings.
Restrictions on our ability to Incur additional Indebtedness are contained in
the covenant described under "--Certain Covenants--Limitation on Indebtedness".
Such restrictions can only be waived with the consent of the holders of a
majority in principal amount of the notes then outstanding. Except for the
limitations contained in such covenants, however, the Indenture will not contain
any covenants or provisions that may afford holders of the notes protection in
the event of a highly leveraged transaction.

    The Credit Agreement will prohibit us from purchasing any notes, and will
also provide that the occurrence of certain change of control events with
respect to the Company would constitute a default thereunder. In the event a
Change of Control occurs at a time when we are prohibited from purchasing notes,
we may seek the consent of our lenders to the purchase of Notes or may attempt
to refinance the borrowings that contain such prohibition. If we do not obtain
such a consent or repay such borrowings, we will remain prohibited from
purchasing notes. In such case, our failure to purchase tendered Notes would
constitute an Event of Default under the indenture which would, in turn,
constitute a default under the Credit Agreement. In such circumstances, the
subordination provisions in the indenture would likely restrict payment to the
Holders of notes.

    Future indebtedness that we may incur may contain prohibitions on the
occurrence of certain events that would constitute a Change of Control or
require the repurchase of such indebtedness upon a Change of Control. Moreover,
the exercise by the holders of their right to require us to repurchase the notes
could cause a default under such indebtedness, even if the Change of Control
itself does not, due to the financial effect of such repurchase on us. Finally,
our ability to pay cash to the holders of notes following the occurrence of a
Change of Control may be limited by our then existing financial resources. There
can be no assurance that sufficient funds will be available when necessary to
make any required repurchases.

    The provisions under the indenture relative to our obligation to make an
offer to repurchase the notes as a result of a Change of Control may be waived
or modified with the written consent of the holders of a majority in principal
amount of the Notes.

LIMITATION ON RESTRICTED PAYMENTS

    (a) The Company will not, and will not permit any Restricted Subsidiary,
directly or indirectly, to make a Restricted Payment if at the time the Company
or such Restricted Subsidiary makes such Restricted Payment:

    (1) a Default shall have occurred and be continuing (or would result

           of their employees); plus

       (C) the amount by which Indebtedness of the Company or its Restricted
           Subsidiaries is reduced on the Company's consolidated balance sheet

           any Person resulting from dividends, repayments of loans or advances

           PROVIDED, HOWEVER, that the foregoing sum shall not exceed, in the
           case of any Person, the amount of Investments previously made (and
           treated as a Restricted Payment) by the Company or any Restricted
           Subsidiary in such Person or, in the case of any Investment
           outstanding on the Issue Date (but not to exceed in the aggregate $10
           million) an amount not to exceed the lesser of the amount of such net
           reduction or the amount of such Investment.

    (b) The preceding provisions will not prohibit:

       the substantially concurrent sale of, or capital contribution in respect
       of, Capital Stock of the Company (other than Disqualified Stock and other

       covenant or this clause (3); PROVIDED, HOWEVER, that the encumbrances and
       restrictions with respect to such Restricted Subsidiary contained in any

       Noteholders than encumbrances and restrictions with respect to such
       Restricted Subsidiary contained in such predecessor agreements;

    (4) any such encumbrance or restriction consisting of customary
       non-assignment provisions in leases or licenses to the extent such
       provisions restrict the transfer of the lease or license or the property
       leased or licensed thereunder;

    (5) any encumbrance or restriction consisting of any restriction on the sale
       or other disposition of assets or property securing Indebtedness as a

LIMITATION ON SALES OF ASSETS AND SUBSIDIARY STOCK

    (a) The Company shall not, and shall not permit any Restricted Subsidiary
to, directly or indirectly, consummate any Asset Disposition unless:

    (1) the Company or such Restricted Subsidiary receives consideration at the
       time of such Asset Disposition at least equal to the fair market value
       (including as to the value of all non-cash consideration), as determined
       in good faith by the Board of Directors, of the shares and assets subject
       to such Asset Disposition;

    (2) at least 75% of the consideration thereof received by the Company or
       such Restricted Subsidiary is in the form of cash or cash equivalents
       (provided that such 75% requirement shall not apply to any Asset
       Disposition in which the cash or cash equivalents portion of the
       consideration received therefor is no less than an amount equal to the
       product of (x) six and (y) the amount of EBITDA directly attributable to
       the assets or Capital Stock included in such Asset Disposition); and

                                      102
<PAGE>
    (3) an amount equal to 100% of the Net Available Cash from such Asset
       Disposition is applied by the Company (or such Restricted Subsidiary, as
       the case may be):

       (A) first, to the extent the Company elects (or is required by the terms
           of any Indebtedness), to prepay, repay, redeem or purchase Senior
           Indebtedness or Indebtedness (other than any Disqualified Stock) of a
           Restricted Subsidiary (in each case other than Indebtedness owed to
           the Company or an Affiliate of the Company) within one year from the
           later of the date of such Asset Disposition or the receipt of such
           Net Available Cash;

       (B) second, to the extent of the balance of such Net Available Cash after
           application in accordance with clause (A), to the extent the Company
           elects, to acquire Additional Assets within one year from the later
           of the date of such Asset Disposition or the receipt of such Net
           Available Cash;

       (C) third, to the extent of the balance of such Net Available Cash after
           application in accordance with clauses (A) and (B), to make an offer
           to the holders of the Notes (and to holders of other Senior
           Subordinated Indebtedness designated by the Company) to purchase
           Notes (and such other Senior Subordinated Indebtedness) pursuant to
           and subject to the conditions contained in the indenture; and

       (D) fourth, to the extent of the balance of such Net Available Cash after
           application in accordance with clauses (A), (B) and (C), for any
           purpose not prohibited by the terms of the indenture;

    PROVIDED, HOWEVER, that in connection with any prepayment, repayment or
purchase of Indebtedness pursuant to clause (A) or (C) above, the Company or
such Restricted Subsidiary shall permanently retire such Indebtedness and shall
cause the related loan commitment (if any) to be permanently reduced in an
amount equal to the principal amount so prepaid, repaid or purchased.

    Notwithstanding the foregoing provisions of this covenant, the Company and
the Restricted Subsidiaries will not be required to apply any Net Available Cash
in accordance with this covenant except to the extent that the aggregate Net
Available Cash from all Asset Dispositions which are not applied in accordance
with this covenant exceeds $10 million. Pending application of Net Available
Cash pursuant to this covenant, such Net Available Cash shall be invested in
Permitted Investments or used to temporarily reduce loans outstanding under
Revolving Credit Facilities.

    For the purposes of this covenant, the following are deemed to be cash or
cash equivalents:

    (1) the assumption of Indebtedness of the Company or any Restricted
       Subsidiary and the release of the Company or such Restricted Subsidiary
       from all liability on such Indebtedness in connection with such Asset
       Disposition; and

    (2) securities received by the Company or any Restricted Subsidiary from the
       transferee that are promptly converted by the Company or such Restricted
       Subsidiary into cash.

    (b) In the event of an Asset Disposition that requires the purchase of the
Notes (and other Senior Subordinated Indebtedness) pursuant to clause (a)(3)(C)
above, the Company will be required to purchase notes tendered pursuant to an
offer by the Company for the notes (and other Senior Subordinated Indebtedness)
at a purchase price of 100% of their principal amount, without premium, plus
accrued but unpaid interest (or, in respect of such other Senior Subordinated
Indebtedness, such lesser price, if any, as may be provided for by the terms of
such Senior Subordinated Indebtedness) in accordance with the procedures
(including prorating in the event of oversubscription) set forth in the
indenture. If the aggregate purchase price of notes (and any other Senior
Subordinated Indebtedness) tendered pursuant to such offer is less than the Net
Available Cash allotted to the purchase thereof, the Company will be required to
apply the remaining Net Available Cash in accordance with clause (a)(3)(D)
above. If the aggregate purchase price of the securities tendered exceeds the
Net Available Cash allotted to purchase

                                      103
<PAGE>
thereof, the Company will select the securities to be purchased on a pro rata
basis but in denominations of $1,000 or multiples thereof. The Company shall not
be required to make such an offer to purchase notes (and other Senior
Subordinated Indebtedness) pursuant to this covenant if the Net Available Cash
available therefor is less than $10 million (which lesser amount shall be
carried forward for purposes of determining whether such an offer is required
with respect to the Net Available Cash from any subsequent Asset Disposition).

    (c) The Company will comply, to the extent applicable, with the requirements
of Section 14(e) of the Exchange Act and any other securities laws or
regulations in connection with the repurchase of notes pursuant to this
covenant. To the extent that the provisions of any securities laws or
regulations conflict with provisions of this covenant, the Company shall comply
with the applicable securities laws and regulations and shall not be deemed to
have breached its obligations under this clause by virtue thereof.

LIMITATION ON AFFILIATE TRANSACTIONS

    (a) The Company will not, and will not permit any Restricted Subsidiary to,
enter into or permit to exist any transaction (including the purchase, sale,
lease or exchange of any property, employee compensation arrangements or the
rendering of any service) with, or for the benefit of, any Affiliate of the
Company (an "Affiliate Transaction") unless:

    (1) the terms of the Affiliate Transaction are no less favorable to the
       Company or such Restricted Subsidiary than those that could be obtained
       at the time of the Affiliate Transaction in arm's-length dealings with a
       Person who is not an Affiliate;

    (2) if such Affiliate Transaction involves an amount in excess of $1
       million, the terms of the Affiliate Transaction are set forth in writing
       and a majority of the non-employee directors of the Company disinterested
       with respect to such Affiliate Transactions have determined in good faith
       that the criteria set forth in clause (1) are satisfied and have approved
       the relevant Affiliate Transaction as evidenced by a Board resolution;
       and

    (3) if such Affiliate Transaction involves an amount in excess of $10
       million, the Board of Directors shall also have received a written
       opinion from an investment banking firm of national prominence that is
       not an Affiliate of the Company to the effect that such Affiliate
       Transaction is fair, from a financial standpoint, to the Company and its
       Restricted Subsidiaries.

    (b) The provisions of the preceding paragraph (a) shall not prohibit:

    (1) any Investment (other than a Permitted Investment) or other Restricted
       Payment, in each case permitted to be made pursuant to the covenant
       described under "--Limitation on Restricted Payments";

    (2) any issuance of securities, or other payments, awards or grants in cash,
       securities or otherwise pursuant to, or the funding of, employment
       arrangements, stock options and stock ownership plans approved by the
       Board of Directors;

    (3) the grant of stock options or similar rights to employees and directors
       of the Company pursuant to plans approved by the Board of Directors;

    (4) loans or advances to employees in the ordinary course of business in
       accordance with the past practices of the Company or its Restricted
       Subsidiaries, but in any event not to exceed $3 million in the aggregate
       outstanding at any one time;

    (5) the payment of reasonable compensation or employee benefit arrangements
       to and indemnity provided for the benefit of directors, officers or
       employees of the Company or its Restricted Subsidiaries in the ordinary
       course of business;

                                      104
<PAGE>
    (6) any employment, noncompetition or confidentiality agreements entered
       into by the Company or any Restricted Subsidiary with its employees in
       the ordinary course of business.

    (7) the payment of reasonable fees to directors of the Company and its
       Restricted Subsidiaries who are not employees of the Company or its
       Restricted Subsidiaries;

    (8) the payment by the Company of fees to Caxton-Iseman and its Affiliates
       in connection with any acquisition transaction entered into by the
       Company or any Restricted Subsidiary; PROVIDED, HOWEVER, that the
       aggregate amount of fees paid to Caxton-Iseman and its Affiliates in
       respect of any acquisition transaction shall not exceed 1% of the total
       acquisition cost of such transaction;

    (9) the accrual (and, to the extent provided below, the payment) by the
       Company of management fees payable to Caxton-Iseman and its Affiliates in
       an amount not to exceed $1 million in any fiscal year of the Company;
       PROVIDED, HOWEVER, that the amount of such fees actually paid in any
       fiscal year does not exeed an amount equal to the sum of (A) in the event
       the Consolidated Coverage Ratio on the date of any proposed payment is
       greater than 2.0 to 1.0 but less than or equal to 2.25 to 1.0, $500,000,
       plus (B) in the event the Consolidated Coverage Ratio on the date of any
       proposed payment exceeds 2.25 to 1.0, an additional $500,000, in each
       case together with the amount of unpaid management fees accrued in any
       prior fiscal year that could have been paid in such prior fiscal year had
       the Consolidated Coverage Ratio applicable to clause (A) or (B) on the
       date of such proposed payment been in effect on the date of accrual of
       such prior year's fee; PROVIDED FURTHER, HOWEVER, that at the time of
       such accrual or payment, no other Default shall have occurred and be
       continuing (or result therefrom);

    (10) any Affiliate Transaction between the Company and a Wholly Owned
       Subsidiary or between Wholly Owned Subsidiaries; and

    (11) the issuance or sale of any Capital Stock (other than Disqualified
       Stock) of the Company.

LIMITATION ON THE SALE OR ISSUANCE OF CAPITAL STOCK OF RESTRICTED SUBSIDIARIES

    The Company shall not sell or otherwise dispose of any Capital Stock of a
Restricted Subsidiary, and shall not permit any Restricted Subsidiary, directly
or indirectly, to issue or sell or otherwise dispose of any of its Capital Stock
except:

    (1) to the Company or a Wholly Owned Subsidiary;

    (2) directors' qualifying shares;

    (3) the issuance of shares of common stock of Interactive Media Corporation
       pursuant to the terms of any agreement or option related thereto as in
       effect on the Acquisition Closing Date;

    (4) if, immediately after giving effect to such issuance, sale or other
       disposition, neither the Company nor any of its Subsidiaries own any
       Capital Stock of such Restricted Subsidiary; or

    (5) if, immediately after giving effect to such issuance, sale or other
       disposition, such Restricted Subsidiary would no longer constitute a
       Restricted Subsidiary and any Investment in such Person remaining after
       giving effect thereto would have been permitted to be made under the
       covenant described under "--Limitation on Restricted Payments" if made on
       the date of such issuance, sale or other disposition.

    Notwithstanding the foregoing, the issuance or sale of shares of Capital
Stock of any Restricted Subsidiary of the Company will not violate the
provisions of the immediately preceding sentence if such shares are issued or
sold in connection with (x) the formation or capitalization of a Restricted
Subsidiary or (y) a single transaction or a series of substantially
contemporaneous transactions whereby such Restricted Subsidiary becomes a
Restricted Subsidiary of the Company by reason of the acquisition of securities
or assets from another Person.

                                      105

MERGER AND CONSOLIDATION

    The Company will not consolidate with or merge with or into, or convey,
transfer or lease, in one transaction or a series of transactions, all or
substantially all its assets to, any Person, unless:

    (1) the resulting, surviving or transferee Person (the "Successor Company")
       shall be a Person organized and existing under the laws of the United
       States of America, any State thereof or the District of Columbia and the
       Successor Company (if not the Company) shall expressly assume, by an
       indenture supplemental thereto, executed and delivered to the Trustee, in
       form reasonably satisfactory to the Trustee, all the obligations of the
       Company under the notes and the indenture;

    (2) immediately after giving effect to such transaction (and treating any
       Indebtedness which becomes an obligation of the Successor Company or any
       Subsidiary as a result of such transaction as having been Incurred by
       such Successor Company or such Subsidiary at the time of such
       transaction), no Default shall have occurred and be continuing;

    (3) immediately after giving effect to such transaction, the Successor
       Company would be able to Incur an additional $1.00 of Indebtedness
       pursuant to paragraph (a) of the covenant described under "--Limitation
       on Indebtedness"; and

    (4) the Company shall have delivered to the Trustee an Officers' Certificate
       and an Opinion of Counsel, each stating that such consolidation, merger
       or transfer and such supplemental indenture (if any) comply with the
       indenture.

    The Company will not permit any Subsidiary Guarantor to consolidate with or
merge with or into, or convey, transfer or lease, in one transaction or a series
of transactions, all or substantially all of its assets to any Person unless:

    (1) the resulting, surviving or transferee Person (if not such Subsidiary)
       shall be a Person organized and existing under the laws of the
       jurisdiction under which such Subsidiary was organized or under the laws
       of the United States of America, or any State thereof or the District of
       Columbia, and such Person shall expressly assume, by a Guaranty
       Agreement, in a form satisfactory to the Trustee, all the obligations of
       such Subsidiary, if any, under its Subsidiary Guaranty;

    (2) immediately after giving effect to such transaction or transactions on a
       pro forma basis (and treating any Indebtedness which becomes an
       obligation of the resulting, surviving or transferee Person as a result
       of such transaction as having been issued by such Person at the time of
       such transaction), no Default shall have occurred and be continuing; and

    (3) the Company delivers to the Trustee an Officers' Certificate and an
       Opinion of Counsel, each stating that such consolidation, merger or
       transfer and such Guaranty Agreement, if any, complies with the
       indenture;

PROVIDED, HOWEVER, that the preceding restrictions will not be applicable if, in
connection with such consolidation, merger, conveyance, transfer or lease, the
Subsidiary Guarantor will be released from its obligations under the Subsidiary
Guaranty as described under "--Guaranties".

    The Successor Company will be the successor to the Company and shall succeed
to, and be substituted for, and may exercise every right and power of, the
Company under the indenture, and the predecessor Company, except in the case of
a lease, shall be released from the obligation to pay the principal of and
interest on the notes.

FUTURE GUARANTORS

    The Company will cause each domestic Restricted Subsidiary organized or
acquired after the Issue Date and that Incurs Indebtedness (including any
Guarantees) to execute and deliver to the Trustee a

                                      106
<PAGE>
Guaranty Agreement pursuant to which such Restricted Subsidiary will Guarantee
payment of the Notes on the same terms and conditions as those set forth in the
indenture.

SEC REPORTS

    Notwithstanding that the Company may not be subject to the reporting
requirements of Section 13 or 15(d) of the Exchange Act, the Company will file
(unless the SEC will not accept such filing) with the SEC and provide the
Trustee and Noteholders with such annual reports and such information, documents
and other reports as are specified in Sections 13 and 15(d) of the Exchange Act
and applicable to a U.S. corporation subject to such Sections, such information,
documents and other reports to be so filed and provided at the times specified
for the filings of such information, documents and reports under such Sections.

    In addition, whether or not required by the SEC, we will file a copy of all
of the information and reports referred to above with the SEC for public
availability within the time periods specified in the SEC's rules and
regulations (unless the SEC will not accept such a filing).

DEFAULTS

    Each of the following is an Event of Default:

    (1) a default in the payment of interest or any Additional Amounts on the
       notes when due, continued for 30 days;

    (2) a default in the payment of principal of any note when due at its Stated
       Maturity, upon optional redemption, upon required repurchase, upon
       declaration or otherwise;

    (3) the failure by the Company to comply with its obligations under
       "--Certain Covenants--Merger and Consolidation" above;

    (4) the failure by the Company to comply for 30 days after written notice
       with any of its obligations in the covenants described above under
       "Change of Control" (other than a failure to purchase notes) or under
       "--Certain Covenants" under "--Limitation on Indebtedness", "--Limitation
       on Restricted Payments", "--Limitation on Restrictions on Distributions
       from Restricted Subsidiaries", "--Limitation on Sales of Assets and
       Subsidiary Stock" (other than a failure to purchase notes), "--Limitation
       on Affiliate Transactions", "--Limitation on the Sale or Issuance of
       Capital Stock of Restricted Subsidiaries", "--Future Guarantors" or
       "--SEC Reports";

    (5) the failure by the Company to comply for 60 days after written notice
       with its other agreements contained in the indenture;

    (6) Indebtedness of the Company or any Significant Subsidiary is not paid
       within any applicable grace period after final maturity or is accelerated
       by the holders thereof because of a default and the total amount of such
       Indebtedness unpaid or accelerated exceeds $5 million (the "cross
       acceleration provision");

    (7) certain events of bankruptcy, insolvency or reorganization of the
       Company, a Subsidiary Guarantor or a Significant Subsidiary (the
       "bankruptcy provisions");

    (8) any judgment or decree for the payment of money in excess of $5 million
       is entered against the Company or a Significant Subsidiary, remains
       outstanding for a period of 60 consecutive days following such judgment
       and is not discharged, waived or stayed within 10 days after written
       notice (the "judgment default provision"); or

    (9) a Subsidiary Guaranty ceases to be in full force and effect (other than
       in accordance with the terms of such Subsidiary Guaranty) or a Subsidiary
       Guarantor denies or disaffirms its obligations under its Subsidiary
       Guaranty.

                                      107
<PAGE>
    However, a default under clauses (4), (5), (6) and (8) will not constitute
an Event of Default until the Trustee or the holders of 25% in principal amount
of the outstanding Notes notify the Company of the default and the Company does
not cure such default within the time specified after receipt of such notice.

    If an Event of Default occurs and is continuing, the Trustee or the holders
of at least 25% in principal amount of the outstanding notes may declare the
principal of and accrued but unpaid interest on all the notes to be due and
payable. Upon such a declaration, such principal and interest shall be due and
payable immediately. If an Event of Default relating to certain events of
bankruptcy, insolvency or reorganization of the Company occurs and is
continuing, the principal of and interest on all the notes will IPSO FACTO
become and be immediately due and payable without any declaration or other act
on the part of the Trustee or any holders of the notes. Under certain
circumstances, the holders of a majority in principal amount of the outstanding
notes may rescind any such acceleration with respect to the notes and its
consequences.

    Subject to the provisions of the indenture relating to the duties of the
Trustee, in case an Event of Default occurs and is continuing, the Trustee will
be under no obligation to exercise any of the rights or powers under the
indenture at the request or direction of any of the holders of the notes unless
such holders have offered to the Trustee reasonable indemnity or security
against any loss, liability or expense. Except to enforce the right to receive
payment of principal, premium (if any) or interest when due, no holder of a note
may pursue any remedy with respect to the indenture or the notes unless:

    (1) such holder has previously given the Trustee notice that an Event of
       Default is continuing;

    (2) holders of at least 25% in principal amount of the outstanding Notes
       have requested the Trustee to pursue the remedy;

    (3) such holders have offered the Trustee reasonable security or indemnity
       against any loss, liability or expense;

    (4) the Trustee has not complied with such request within 60 days after the
       receipt thereof and the offer of security or indemnity; and

    (5) holders of a majority in principal amount of the outstanding Notes have
       not given the Trustee a direction inconsistent with such request within
       such 60-day period.

Subject to certain restrictions, the holders of a majority in principal amount
of the outstanding Notes are given the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or of
exercising any trust or power conferred on the Trustee. The Trustee, however,
may refuse to follow any direction that conflicts with law or the indenture or
that the Trustee determines is unduly prejudicial to the rights of any other
holder of a Note or that would involve the Trustee in personal liability.

    If a Default occurs, is continuing and is known to the Trustee, the Trustee
must mail to each holder of the notes notice of the Default within 90 days after
it occurs. Except in the case of a Default in the payment of principal of or
interest on any note, the Trustee may withhold notice if and so long as a
committee of its trust officers determines that withholding notice is not
opposed to the interest of the holders of the notes. In addition, we are
required to deliver to the Trustee, within 120 days after the end of each fiscal
year, a certificate indicating whether the signers thereof know of any Default
that occurred during the previous year. We are required to deliver to the
Trustee, within 30 days after the occurrence thereof, written notice of any
event which would constitute certain Defaults, their status and what action we
are taking or proposes to take in respect thereof.

AMENDMENTS AND WAIVERS

    Subject to certain exceptions, the indenture may be amended with the consent
of the holders of a majority in principal amount of the notes then outstanding
(including consents obtained in connection with

                                      108
<PAGE>
a tender offer or exchange for the notes) and any past default or compliance
with any provisions may also be waived with the consent of the holders of a
majority in principal amount of the notes then outstanding. However, without the
consent of each holder of an outstanding note affected thereby, an amendment may
not, among other things:

    (1) reduce the amount of notes whose holders must consent to an amendment;

    (2) reduce the rate of or extend the time for payment of interest on any
       note;

    (3) reduce the principal of or extend the Stated Maturity of any note;

    (4) reduce the amount payable upon the redemption of any Note or change the
       time at which any note may be redeemed as described under "--Optional
       Redemption" above;

    (5) make any note payable in money other than that stated in the note;

    (6) impair the right of any holder of the notes to receive payment of
       principal of and interest on such holder's notes on or after the due
       dates therefor or to institute suit for the enforcement of any payment on
       or with respect to such holder's notes;

    (7) make any change in the amendment provisions which require each holder's
       consent or in the waiver provisions;

    (8) make any change in the ranking or priority of any Note that would
       adversely affect the Noteholders; or

    (9) make any change in any Subsidiary Guaranty that would adversely affect
       the Noteholders.

    Notwithstanding the preceding, without the consent of any holder of the
Notes, the Company and Trustee may amend the indenture:

    (1) to cure any ambiguity, omission, defect or inconsistency;

    (2) to provide for the assumption by a successor corporation of the
       obligations of the Company under the indenture;

    (3) to provide for uncertificated notes in addition to or in place of
       certificated notes (provided that the uncertificated notes are issued in
       registered form for purposes of Section 163(f) of the Code, or in a
       manner such that the uncertificated notes are described in Section
       163(f)(2)(B) of the Code);

    (4) to add guarantees with respect to the notes and secure the notes;

    (5) to add to the covenants of the Company for the benefit of the holders of
       the notes or to surrender any right or power conferred upon the Company;

    (6) to make any change that does not adversely affect the rights of any
       holder of the notes; or

    (7) to comply with any requirement of the SEC in connection with the
       qualification of the Indenture under the Trust Indenture Act.

    However, no amendment may be made to the subordination provisions of the
indenture that adversely affects the rights of any holder of Senior Indebtedness
then outstanding unless the holders of such Senior Indebtedness (or their
Representative) consents to such change.

    The consent of the holders of the notes is not necessary under the indenture
to approve the particular form of any proposed amendment. It is sufficient if
such consent approves the substance of the proposed amendment.

                                      109
<PAGE>
    After an amendment under the indenture becomes effective, we are required to
mail to holders of the Notes a notice briefly describing such amendment.
However, the failure to give such notice to all holders of the Notes, or any
defect therein, will not impair or affect the validity of the amendment.

TRANSFER

    The notes will be issued in registered form and will be transferable only
upon the surrender of the notes being transferred for registration of transfer.
We may require payment of a sum sufficient to cover any tax, assessment or other
governmental charge payable in connection with certain transfers and exchanges.

DEFEASANCE

    At any time, we may terminate all our obligations under the notes and the
indenture ("legal defeasance"), except for certain obligations, including those
respecting the defeasance trust and obligations to register the transfer or
exchange of the notes, to replace mutilated, destroyed, lost or stolen notes and
to maintain a registrar and paying agent in respect of the notes.

    In addition, at any time we may terminate our obligations under "--Change of
Control" and under the covenants described under "--Certain Covenants" (other
than the covenant described under "--Merger and Consolidation"), the operation
of the cross acceleration provision, the bankruptcy provisions with respect to
Significant Subsidiaries and the judgment default provision described under
"--Defaults" above and the limitations contained in clauses (3) under "--Certain
Covenants--Merger and Consolidation" above ("covenant defeasance").

    We may exercise our legal defeasance option notwithstanding our prior
exercise of our covenant defeasance option. If we exercise our legal defeasance
option, payment of the notes may not be accelerated because of an Event of
Default with respect thereto. If we exercise our covenant defeasance option,
payment of the notes may not be accelerated because of an Event of Default
specified in clause (4), (6), (7) (with respect only to Significant
Subsidiaries) or (8) under "--Defaults" above or because of the failure of the
Company to comply with clause (3) under "--Certain Covenants--Merger and
Consolidation" above. If we exercise our legal defeasance option or our covenant
defeasance option, each Subsidiary Guarantor will be released from all of its
obligations with respect to its Subsidiary Guaranty and the Security Agreements.

    In order to exercise either of our defeasance options, we must irrevocably
deposit in trust (the "defeasance trust") with the Trustee money or U.S.
Government Obligations for the payment of principal of and interest on the notes
to redemption or maturity, as the case may be, and must comply with certain
other conditions, including delivery to the Trustee of an Opinion of Counsel to
the effect that holders of the notes will not recognize income, gain or loss for
Federal income tax purposes as a result of such deposit and defeasance and will
be subject to Federal income tax on the same amounts and in the same manner and
at the same times as would have been the case if such deposit and defeasance had
not occurred (and, in the case of legal defeasance only, such Opinion of Counsel
must be based on a ruling of the Internal Revenue Service or other change in
applicable Federal income tax law).

CONCERNING THE TRUSTEE AND EXCHANGE AGENT

    IBJ Whitehall Bank & Trust Company is to be the Trustee under the indenture,
and we have also appointed it as Registrar, Paying Agent and Exchange Agent with
regard to the notes.

    The indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases, or to realize on certain property received in respect of any such
claim as security or otherwise. The Trustee will be permitted to engage in other

                                      110
<PAGE>
transactions; PROVIDED, HOWEVER, if it acquires any conflicting interest it must
either eliminate such conflict within 90 days, apply to the SEC for permission
to continue or resign.

    The Holders of a majority in principal amount of the outstanding notes will
have the right to direct the time, method and place of conducting any proceeding
for exercising any remedy available to the Trustee, subject to certain
exceptions. If an Event of Default occurs (and is not cured), the Trustee will
be required, in the exercise of its power, to use the degree of care of a
prudent man in the conduct of his own affairs. Subject to such provisions, the
Trustee will be under no obligation to exercise any of its rights or powers
under the indenture at the request of any Holder of notes, unless such Holder
shall have offered to the Trustee security and indemnity satisfactory to it
against any loss, liability or expense and then only to the extent required by
the terms of the indenture.

GOVERNING LAW

    The indenture and the notes will be governed by, and construed in accordance
with, the laws of the State of New York without giving effect to applicable
principles of conflicts of law to the extent that the application of the law of
another jurisdiction would be required thereby.

(1) if the Company or any Restricted Subsidiary has Incurred any Indebtedness
    since the beginning of such period that remains outstanding or if the

    any revolving credit facility unless such Indebtedness has been permanently
    repaid and has not been replaced) on the date of the transaction giving rise
    to the need to calculate the Consolidated Coverage Ratio, EBITDA and

    period and as if the Company or such Restricted Subsidiary has not earned
    the interest income actually earned during such period in respect of cash or
    Temporary Cash Investments used to repay, repurchase, defease or otherwise
    discharge such Indebtedness,

(3) if since the beginning of such period the Company or any Restricted
    Subsidiary shall have made any Asset Disposition, the EBITDA for such period
    shall be reduced by an amount equal to the EBITDA (if positive) directly
    attributable to the assets which are the subject of such Asset Disposition
    for such period, or increased by an amount equal to the EBITDA (if
    negative), directly attributable thereto for such period and Consolidated
    Interest Expense for such period shall be reduced by an amount equal to the
    Consolidated Interest Expense directly attributable to any Indebtedness of
    the Company or any Restricted Subsidiary repaid, repurchased, defeased or

    in connection with a transaction requiring a calculation to be made

<PAGE>
    substantially all of a business or a product line, operating unit or similar
    portion of a business, EBITDA and Consolidated Interest Expense for such
    period shall be calculated after giving pro forma effect thereto (including
    the Incurrence of any Indebtedness) as if such Investment or acquisition
    occurred on the first day of such period and

(5) if since the beginning of such period any Person (that subsequently became a
    Restricted Subsidiary or was merged with or into the Company or any
    Restricted Subsidiary since the beginning of such period) shall have made
    any Asset Disposition, any Investment or acquisition of assets that would
    have required an adjustment pursuant to clause (3) or (4) above if made by
    the Company or a Restricted Subsidiary during such period, EBITDA and
    Consolidated Interest Expense for such period shall be calculated after
    giving pro forma effect thereto as if such Asset Disposition, Investment or
    acquisition occurred on the first day of such period.

eliminations of selling, general and administrative expenses as determined by a
responsible financial or accounting Officer of the Company in good faith in
connection with the Company's consideration of such transaction and consistent
with the Company's experience in similar transactions less (B) the incremental
expenses that would be included in cost of revenues and selling, general and
administrative expenses that would have been incurred by the Company or its
Restricted Subsidiaries, as applicable, in the operation or ownership of such
acquired assets during such period. If any Indebtedness bears a floating rate of
interest and is being given pro forma effect, the interest of such Indebtedness
shall be calculated as if the rate in effect on the date of determination had
been the applicable rate for the entire period (taking into account any Interest
Rate Agreement applicable to such Indebtedness if such Interest Rate Agreement
has a remaining term in excess of 12 months).

    "CONSOLIDATED INTEREST EXPENSE" means, for any period, the total interest

    LESS, to the extent included in such total interest expense, the

THE DEPOSITORY TRUST COMPANY'S PROCEDURES

    For your convenience, we are providing you with a description of the
operations and procedures of The Depository Trust Company. The operations and
procedures of The Depository Trust Company are solely within the control of its
settlement system however and may change from time to time. We are not
responsible for these operations and procedures and urge you to contact The
Depository Trust Company or its participants directly to discuss these matters.

    The Depository Trust Company has advised us that it is a limited-purpose
trust company created to hold securities for its participating organizations and
to facilitate the clearance and settlement of transactions in those securities
between its participants through electronic book entry changes in the accounts
of these participants. These direct participants include securities brokers and
dealers, banks, trust companies, clearing corporations and other organizations.
Access to The Depository Trust Company's system is also indirectly available to
other entities that clear through or maintain a direct or indirect, custodial
relationship with a direct participant. The Depository Trust Company may hold
securities beneficially owned by other persons only through its participants and
the ownership interests and transfers of ownership interests of these other
persons will be recorded only on the records of the participants and not on the
records of The Depository Trust Company.

    The Depository Trust Company has also advised us that, in accordance with
its procedures, (1) upon deposit of the global notes, it will credit the
accounts of the direct participants with an interest in the global notes, and
(2) it will maintain records of the ownership interests of these direct
participants in the global notes and the transfer of ownership interests by and
between direct participants. The Depository Trust Company will not maintain
records of the ownership interests of, or the transfer of ownership interests by
and between, indirect participants or other owners of beneficial interests in
the global notes. Both direct and indirect participants must maintain their own
records of ownership interests of, and the transfer of ownership interests by
and between, indirect participants and other owners of beneficial interests in
the global notes.

    Investors in the global notes may hold their interests in the notes directly
through The Depository Trust Company if they are direct participants in The
Depository Trust Company or indirectly through organizations that are direct
participants in The Depository Trust Company. All interests in a global note may
be subject to the procedures and requirements of The Depository Trust Company.

    The laws of some states require that some persons take physical delivery in
definitive certificated form of the securities that they own. This may limit or
curtail the ability to transfer beneficial interests in a global note to these
persons. Because The Depository Trust Company can act only on behalf of direct
participants, which in turn act on behalf of indirect participants and others,
the ability of a person having a beneficial interest in a global note to pledge
its interest to persons or entities that are not direct participants in The
Depository Trust Company or to otherwise take actions in respect of its
interest, may be affected by the lack of physical certificates evidencing the
interests.

    Except as described below, owners of interests in the global notes will not
have notes registered in their names, will not receive physical delivery of
notes in certificated form and will not be considered the registered owners or
holders of these notes under the indenture for any purpose.

    Payments with respect to the principal of and interest on any notes
represented by a global note registered in the name of The Depository Trust
Company or its nominee on the applicable record date will be payable by the
trustee to or at the direction of The Depository Trust Company or its nominee in
its capacity as the registered holder of the global note representing these
notes under the indenture. Under the terms of the indenture, we and the trustee
will treat the person in whose names the notes are registered, including notes
represented by global notes, as the owners of the notes for the purpose of
receiving payments and for any and all other purposes whatsoever. Payments in
respect of the principal and interest on global notes registered in the name of
The Depository Trust Company or its nominee will be

                                      126
<PAGE>
payable by the trustee to The Depository Trust Company or its nominee as the
registered holder under the indenture. Consequently, none of Anteon, the trustee
or any of our agents, or the trustee's agents has or will have any
responsibility or liability for (1) any aspect of The Depository Trust Company's
records or any direct or indirect participant's records relating to, or payments
made on account of, beneficial ownership interests in the global notes or for
maintaining, supervising or reviewing any of The Depository Trust Company's
records or any direct or indirect participant's records relating to the
beneficial ownership interests in any global note or (2) any other matter
relating to the actions and practices of The Depository Trust Company or any of
its direct or indirect participants.

    The Depository Trust Company has advised us that its current practice, upon
receipt of any payment in respect of securities such as the notes, including
principal and interest, is to credit the accounts of the relevant participants
with the payment on the payment date, in amounts proportionate to their
respective holdings in the principal amount of beneficial interest in the
security as shown on its records, unless it has reasons to believe that it will
not receive payment on the payment date. Payments by the direct and indirect
participants to the beneficial owners of interests in the global note will be
governed by standing instructions and customary practice and will be the
responsibility of the direct or indirect participants and will not be the
responsibility of The Depository Trust Company, the trustee or us.

    Neither Anteon nor the trustee will be liable for any delay by The
Depository Trust Company or any direct or indirect participant in identifying
the beneficial owners of the notes and Anteon and the trustee may conclusively
rely on, and will be protected in relying on, instructions from The Depository
Trust Company for all purposes, including with respect to the registration and
delivery, and the respective principal amounts, of the notes.

    Transfers between participants in The Depository Trust Company will be
effected in accordance with The Depository Trust Company's procedures, and will
be settled in same day funds.

    The Depository Trust Company has advised us that it will take any action
permitted to be taken by a holder of notes only at the direction of one or more
participants to whose account The Depository Trust Company has credited the
interests in the global notes and only in respect of the portion of the
aggregate principal amount of the notes as to which the participant or
participants has or have given that direction. However, if there is an event of
default with respect to the notes, The Depository Trust Company reserves the
right to exchange the global notes for legended notes in certificated form and
to distribute them to its participants.

    Although The Depository Trust Company has agreed to these procedures to
facilitate transfers of interests in the global notes among participants in The
Depository Trust Company, it is under no obligation to perform or to continue to
perform these procedures and may discontinue them at any time. None of Anteon,
the trustee or any of our or the trustee's respective agents will have any
responsibility for the performance by The Depository Trust Company and its
direct or indirect participants of their respective obligations under the rules
and procedures governing their operations.

EXCHANGE OF BOOK-ENTRY NOTES FOR CERTIFICATED NOTES

    A global note will be exchangeable for definitive notes in registered
certificated form if:

    (1) The Depository Trust Company notifies us that it is unwilling or unable
       to continue as depository for the global notes and we fail to appoint a
       successor depository within 90 days,

    (2) The Depository Trust Company ceases to be a clearing agency registered
       under the Exchange Act,

    (3) we elect to cause the issuance of the certificated notes upon a notice
       of the trustee,

    (4) a default or event of default under the indenture for the notes has
       occurred and is continuing, or

                                      127
<PAGE>
    (5) a request to that effect is made but only upon prior written notice
       given to the trustee by or on behalf of The Depository Trust Company in
       accordance with the indenture.

    In all cases, certificated notes delivered in exchange for any global note
or beneficial interests in a global note will be registered in the name, and
issued in any approved denominations, requested by or on behalf of The
Depository Trust Company, in accordance with its customary procedures.

SAME DAY SETTLEMENT

    We expect that the interests in the global notes will be eligible to trade
in The Depository Trust Company's Same-Day Funds Settlement System. As a result,
secondary market trading activity in these interests will settle in immediately
available funds, subject in all cases to the rules and procedures of The
Depository Trust Company and its participants. We expect that secondary trading
in any certificated notes will also be settled in immediately available funds.

PAYMENT

    The indenture requires that payments in respect of the notes represented by
global notes, including principal and interest, be made by wire transfer of
immediately available funds to the accounts specified by the holder of the
global notes. With respect to notes in certificated form, we will make all
payments of principal and interest on the notes at our office or agency
maintained for that purpose within the city and state of New York. This office
will initially be the office of the paying agent maintained for that purpose. At
our option however, we may make these installments of interest by (1) check
mailed to the holders of notes at their respective addresses provided in the
register of holder of notes or (2) transfer to an account located in the United
States maintained by the payee.

YEAR 2000

    The Depository Trust Company has advised us that its management is aware
that some computer applications, systems, and the like for processing data that
are dependent upon calendar dates, including dates before, on and after January
1, 2000, may encounter year 2000 problems. The Depository Trust Company has
informed its participants and other members of the financial community that it
has developed and is implementing a program so that its systems, as the same
relate to the timely payment of distributions, including principal and interest
payments, to security holders, book-entry deliveries and settlement of trades
within The Depository Trust Company, continue to function appropriately. This
program includes a technical assessment and a remediation plan, each of which is
complete. Additionally, The Depository Trust Company's plan includes a testing
phase, which is expected to be completed within the appropriate time frame.
However, The Depository Trust Company's ability to perform its services properly
is also dependent upon other parties, including issuers and their agents, as
well as third party vendors from whom The Depository Trust Company licenses
software and hardware, and third party vendors on whom The Depository Trust
Company relies for information or the provision of services, including
telecommunication and electrical utility service providers, among others. The
Depository Trust Company has informed its participants and other members of the
financial community that it is contacting and will continue to contact third
party vendors from whom The Depository Trust Company acquires services to:

    - impress upon them the importance of these services being year 2000
      compliant, and

    - determine the extent of their efforts for year 2000 remediation and, as
      appropriate, testing of their services.

    In addition, The Depository Trust Company is in the process of developing
contingency plans as it deems appropriate. According to The Depository Trust
Company, the above information with respect to The Depository Trust Company has
been provided to its participants and other members of the financial community
for informational purposes only and is not intended to serve as a
representation, warranty or contract modification of any kind.

            CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

GENERAL

    The following general discussion summarizes certain of the material U.S.
Federal income and estate tax aspects of the exchange of initial notes for
exchange notes in accordance with the exchange offer, and the ownership and
disposition of the exchange notes. This discussion is a summary for general
information only and is limited in the following ways:

    - The discussion only covers holders of exchange notes that exchange initial
      notes for exchange notes in accordance with the exchange offer.

    - The discussion only covers holders of exchange notes that hold the
      exchange notes as capital assets (that is, for investment purposes), and
      that do not have a special tax status.

    - The discussion covers only the general tax consequences to holders of the
      exchange notes. It does not cover tax consequences that depend upon a
      holder's individual tax circumstances.

    - The discussion is based on current law. Changes in the law may change the
      tax treatment of the exchange notes on a prospective or retroactive basis.

    - The discussion does not cover state, local or foreign law.

    - The discussion does not apply to holders owning 10% or more of the voting
      stock of the Company, or corporate holders that are controlled foreign
      corporations with respect to the Company.

    We have not sought and will not seek any rulings or opinions from the
Internal Revenue Service or counsel with respect to the matters discussed below.
There can be no assurance that the Internal Revenue Service will not take
positions about the tax treatment of the exchange notes which are different from
those that we discuss.

    THE FOLLOWING DISCUSSION IS FOR GENERAL INFORMATION ONLY. THE TAX TREATMENT
MAY VARY DEPENDING UPON A HOLDER'S PARTICULAR SITUATION. HOLDERS SHOULD CONSULT
THEIR OWN TAX ADVISORS AS TO THE PARTICULAR TAX CONSEQUENCES TO THEM OF THE
EXCHANGE OFFER AND THE OWNERSHIP OF THE INITIAL NOTES OR THE EXCHANGE NOTES,
INCLUDING THE APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR FOREIGN TAX LAWS.

    The tax consequences depend upon whether you are a U.S. holder or a non-U.S.
holder. A U.S. holder is:

    - a citizen or resident of the United States;

    - a corporation, partnership or other entity created or organized under U.S.
      law (Federal or state);

    - an estate the income of which is subject to U.S. Federal income taxation
      regardless of its sources;

    - a trust if a U.S. court is able to exercise primary jurisdiction over
      administration of the trust and one or more U.S. persons have authority to
      control all substantial decisions of the trust; or

    - any other person whose worldwide income and gain is otherwise subject to
      U.S. Federal income taxation on a net basis.

    A non-U.S. holder is a holder that is not a U.S. holder.

                                      129
<PAGE>
TAXATION OF HOLDERS ON EXCHANGE

    The exchange of initial notes for exchange notes in accordance with the
exchange offer will not be treated as an exchange or otherwise as a taxable
event to holders. Consequently, the tax treatment to the holders on the exchange
will be as follows:

    - no gain or loss will be realized by a holder upon receipt of an exchange
      note;

    - the holding period of the exchange note will include the holding period of
      the initial note exchanged the exchange note; and

    - the adjusted tax basis of the exchange note will be the same as the
      adjusted tax basis of the initial note exchanged for the exchange note
      immediately before the exchange.

    Further, the U.S. tax consequences of ownership and disposition of any
exchange note should be the same as the U.S. tax consequences of ownership and
disposition of an initial note. See "Tax Consequences to U.S. Holders; Sale,
Exchange or Redemption of the Notes" and "Tax Consequences to Non-U.S. Holders;
Sale, Exchange or Redemption of the Notes" below.

TAX CONSEQUENCES TO U.S. HOLDERS

    INTEREST

    - If you are a cash method taxpayer (including most individual holders), you
      must report the interest on your income when it is received by you.

    - If you are an accrual method taxpayer, you must report the interest on
      your income as it accrues.

    REGISTERED EXCHANGE OFFER

    Under certain circumstances described above, we will be required to pay
additional interest on the Notes if we fail to comply with certain of our
obligations under the Registration Rights Agreement. See "Description of the
Notes--Registered Exchange Offer; Registration Rights." Although the matter is
not free from doubt, such additional interest should be treated as a payment of
additional interest on the exchange notes for U.S. Federal income tax purposes,
with the following results:

    - If you are a cash method taxpayer (including most individual holders),
      such additional interest will be taxable to you as ordinary income when it
      is received by you.

    - If you are an accrual method taxpayer, such additional interest will be
      taxable to you as ordinary income as it accrues.

    It is possible, however, that the Internal Revenue Service may take a
different position, in which case you might be required to include such
additional interest in income as it accrues or becomes fixed (regardless of your
regular method of accounting).

    SALE, EXCHANGE OR REDEMPTION OF THE NOTES

    On a sale, exchange, retirement or other disposition of an exchange note:

    - You will have taxable gain or loss equal to the difference between the tax
      basis of the note and amount received on the sale, exchange, retirement or
      other disposition.

    - Any gain or loss will generally be capital gain or loss, and will be
      long-term capital gain or loss if the Note was held for more than one
      year.

    - If you sell the exchange note between interest payment dates, a portion of
      the amount you receive reflects interest that has accrued on the exchange
      note but has not yet been paid by the sale date. That amount is treated as
      ordinary interest income and not as sale proceeds.

                                      130
<PAGE>
    - You will not have any taxable gain or loss if the notes are exchanged for
      exchange notes in the Registered Exchange Offer. You will have the same
      basis and holding period in the exchange notes as you had in the notes.

    INFORMATION REPORTING AND BACKUP WITHHOLDING

    Under the tax rules concerning information reporting to the Internal Revenue
Service:

    - We are required to provide information to the Internal Revenue Service
      concerning interest and redemption proceeds we pay to you on exchange
      notes held by you, unless an exemption applies.

    - Similarly, unless an exemption applies, you are required to provide us
      with a correct taxpayer identification number for our use in reporting
      information to the Internal Revenue Service. If you are an individual,
      this is your social security number. You are also required to comply with
      other Internal Revenue Service requirements concerning information
      reporting.

    - If you are subject to these requirements but do not comply, we are
      required to withhold 31% of all amounts payable to you on the exchange
      notes (including principal payments). If we do withhold part of a payment,
      you may use the withheld amount as a credit against your Federal income
      tax liability.

    - All U.S. holders that are individuals are subject to these requirements.
      Certain U.S. holders, including all corporations, tax-exempt organizations
      and individual retirement accounts, are exempt from these requirements.

TAX CONSEQUENCES TO NON-U.S. HOLDERS

    WITHHOLDING TAXES

    If you are a non-U.S. holder, payments of principal and interest on the
exchange notes generally will not be subject to U.S. withholding taxes. However,
in order for the exemption from withholding taxes to apply, you must meet the
following requirements:

    - As the beneficial owner of an exchange note, you must provide a statement
      to the effect that you are not a U.S. holder. This statement is generally
      made on Internal Revenue Service Form W-8. You should consult your own tax
      advisor about the specific method to satisfy this requirement.

    - You must not be a bank that is making a loan in the ordinary course of its
      business.

    Non-U.S. holders that do not qualify for exemption from withholding
generally will be subject to withholding of U.S. Federal income tax at a rate of
30%, or lower applicable treaty rate.

    New Treasury regulations generally effective for payments made after
December 31, 1999 provide alternative methods for satisfying the certification
requirements described above. The Internal Revenue Service recently issued a
notice announcing the intent of the Treasury Department and the Internal Revenue
Service to amend these regulations so that they normally will not apply to
payments made before January 1, 2001. These regulations also will require, in
the case of notes held by a foreign partnership, that the certification be
provided by the partners rather than by the foreign partnership and that the
partnership provide specified information, including a U.S. taxpayer
identification number.

    SALE, EXCHANGE OR REDEMPTION OF THE NOTES

    If you sell an exchange note or it is redeemed, you will not be subject to
U.S. Federal income tax on any gain unless either of the following applies:

    - The gain is connected with a trade or business that you conduct in the
      U.S.

                                      131
<PAGE>
    - You are an individual and are present in the U.S. for at least 183 days
      during the year in which you dispose of the note, and certain other
      conditions are satisfied.

    U.S. TRADE OR BUSINESS

    If you hold an exchange note in connection with a trade or business that you
are conducting in the U.S.:

    - Any interest on the Note, and any gain from disposing of the exchange
      note, generally will be subject to income tax as if you were a U.S.
      holder.

    - Any interest and gain will be exempt from U.S. withholding tax as
      discussed above as long as you submit to us a proper form, generally
      Internal Revenue Service Form 4224, that includes certain required
      information. You should consult your own tax advisor about how to satisfy
      this requirement. The procedures for satisfying this requirement will
      change on January 1, 2000.

    - If you are a corporation, you may be subject to a branch profits tax on
      your earnings that are connected with your U.S. trade or business,
      including earnings from the exchange note. This tax is 30%, but may be
      reduced or eliminated by an applicable income tax treaty.

    ESTATE TAXES

    If you are an individual non-U.S. holder, the exchange note will not be
subject to U.S. estate tax when you die. However, this rule only applies if, at
the time of your death, payments on the exchange note would not have been
connected to a trade or business that you were conducting in the U.S.

    INFORMATION REPORTING AND BACKUP WITHHOLDING

    U.S. rules concerning information reporting and backup withholding are
described above. You automatically avoid these requirements when you provide the
tax certifications needed to avoid withholding tax on interest, as described
above (unless we know, or an intermediate entity knows, that the certification
is false). See "Withholding Taxes" above.

    Similarly, if you dispose of an exchange note through a broker:

    - You must provide the broker appropriate certification of your non-U.S.
      status to avoid information reporting and backup withholding.

    - If you do not provide such certification, and you use the U.S. office of a
      broker, you may be subject to information reporting and backup
      withholding.

    - If you do not provide such certification, and you use the non-U.S. office
      of a broker, you will not be subject to backup withholding. However, you
      may be subject to information reporting depending on whether the broker
      has certain connections to the U.S.

    You should consult your tax advisor about the tax rules concerning
information reporting requirements and backup withholding.

    THE ABOVE SUMMARY DOES NOT DISCUSS ALL ASPECTS OF U.S. FEDERAL INCOME
TAXATION THAT MAY BE RELEVANT TO A PARTICULAR HOLDER OF EXCHANGE NOTES OR
INITIAL NOTES IN LIGHT OF THAT HOLDER'S PARTICULAR CIRCUMSTANCES AND INCOME TAX
SITUATION. HOLDERS OF NOTES SHOULD CONSULT THEIR OWN TAX ADVISORS AS TO THE
SPECIFIC CONSEQUENCES TO THEM OF THE EXCHANGE OFFER AND THE OWNERSHIP OF THE
INITIAL NOTES OR THE EXCHANGE NOTES, INCLUDING THE APPLICATION AND EFFECT OF
STATE, LOCAL, FOREIGN AND OTHER TAX LAWS, OR SUBSEQUENT REVISIONS OF THESE TAX
LAWS.

                              PLAN OF DISTRIBUTION

    Each broker-dealer that receives exchange notes for its own account pursuant
to the exchange offer in exchange for initial notes acquired by such
broker-dealer as a result of market making or other trading activities may be
deemed to be an "underwriter" within the meaning of the Securities Act and,
therefore, must deliver a prospectus meeting the requirements of the Securities
Act in connection with any resales, offers to resell or other transfers of the
exchange notes received by it in connection with the exchange offer.
Accordingly, each such broker-dealer must acknowledge that it will deliver a
prospectus meeting the requirements of the Securities Act in connection with any
resale of such exchange notes. The letter of transmittal states that by
acknowledging that it will deliver and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act. This prospectus, as it may be amended or
supplemented from time to time, may be used by a broker-dealer in connection
with resales of exchange notes received in exchange for initial notes where such
initial notes were acquired as a result of market-making activities or other
trading activities.

    We will not receive any proceeds from any sale of exchange notes by
broker-dealers. Exchange notes received by broker-dealers for their own account
pursuant to the exchange offer may be sold from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions, through
the writing of options on the exchange notes or a combination of such methods of
resale, at market prices prevailing at the time of resale, at prices related to
such prevailing market prices or negotiated prices. Any such resale may be made
directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any such
broker-dealer and/or the purchasers of any such exchange notes. Any
broker-dealer that resells exchange notes that were received by it for its own
account pursuant to the exchange offer and any broker or dealer that
participates in a distribution of such exchange notes may be deemed to be an
"underwriter" within the meaning of the Securities Act and any profit of any
such resale of exchange notes and any commissions or concessions received by any
such persons may be deemed to be underwriting compensation under the Securities
Act. The letter of transmittal states that by acknowledging that it will deliver
and by delivering a prospectus, a broker-dealer will not be deemed to admit that
it is an "underwriter" within the meaning of the Securities Act.

                               GLOSSARY OF TERMS

    BACKLOG--Backlog represents orders under prime contracts with the Federal
government and subcontracts under Federal government prime contracts. Contract
backlog is based on management's estimate of future revenues to be derived from
existing contracts. There are no assurances that all of such backlog will be
recognized as revenue. Funded backlog consists of the aggregate dollar portion
of our contracts for which funding has been contractually authorized by the
government and earmarked for expenditure under such contracts.

    CAS--Federal law requires certain government contractors and subcontractors
to comply with prescribed Cost Accounting Standards and to disclose in writing
and follow consistently their cost accounting practices. The DCAA uses the CAS
when auditing costs incurred by contractors in the performance of government
contracts.

    C(4)I--Command, control, computers, communications and intelligence systems.

    C(4)ISR--Command, control, computers, communications, intelligence,
surveillance and reconnaissance services.

    CMOS--The Cargo Movement Operations System is a logistics system to automate
the tracking of all equipment and cargo movement operations for the Air Force.

and the first standard Air Force client/server application to be installed.

    COTS--Commercial off-the-shelf hardware and software products which are,
unlike customized systems, more open, modular and scaleable, less costly and in
some instances better suited to meet the needs of the Federal government.

    DCAA--The Defense Contract Audit Agency performs all contract auditing for
the Department of Defense and provides financial and accounting advice to
government contracting officers who execute and administer government contracts.
The DCAA is involved in virtually every phase of the procurement process, from
the pre-award survey of contractor capability to the audit of final costs
claimed on completion of cost-reimbursement contracts. The federal government
has the right to audit a company for three years after the final payment for
compliance with contract terms.

    FAR--The Federal Acquisition Regulations, which regulate almost all aspects
governing the formation, administration and performance of U.S. Federal
government contracts.

    FEMA--The Federal Emergency Management Agency works in coordination with
state and local government to provide a national response to emergencies (I.E.,
a tornado, hurricane, earthquake or fire). FEMA responds to emergencies and, if
required, allocates Federal funds to help repair or replace property damage or
assist victims.

    GSA--The General Services Administration acts as a program administrator
and, in order for a company to provide services under a GSA contract, the
company must be pre-qualified and selected by the GSA.

system used by government purchasing officials to buy goods and services from
GSA Schedules.

    GSA SCHEDULES--The GSA awards indefinite quantity fixed price contracts to
contractors for stated periods of time, through which individual agencies may
place orders, receive shipments from and make payments directly to contractors.
The contracts are awarded under either the sealed-bid method or the negotiated
method of procurement and are placed on "lists," or schedules, according to the
product/ service type. These schedules identify the supplies and services
available to authorized government agencies by contract and include the names,
addresses, and phone numbers of the GSA Schedule

                                      135
<PAGE>
contractors. The Automated Data Processing schedule provides for the procurement
of mainframe and minicomputers, peripherals, software, supplies, and recently
services. Contractors authorized to participate in the GSA Schedule program are
eligible to market products and services to a broad range of Federal government
customers.

    IDIQ--Indefinite Delivery, Indefinite Quantity type contracts are generally
contracts for which the exact times and/or quantities of future deliveries are
not known at the time of contract award. Apart from a small minimum purchase
obligation by the government, an IDIQ contract provides no firm commitment of
work to be ordered by the government.

    ITMRA--The Information Technology Management Reform Act of 1996. This
statute changed the Federal government's process of procuring information
technology by (i) placing increased attention on the cost effectiveness of
information technology and return on investment and performance and (ii) making
individual agencies accountable and responsible of oversight for information
technology budgets.

    LOCE--The Linked Operations/Intelligence Centers Europe Program is a program
which provides a common view of intelligence derived from multiple sources for

and/or services for which one or more competing contractors are or were
incumbent contractor(s) under an expiring or expired contract that required
services substantially similar to those which are the subject of the new
procurement.

    RFP--A Request for Proposal is a detailed document used in the procurement
process by government agencies to solicit offers from interested contractors.
The RFP typically contains a description of the scope of work to be performed by
(or that may be ordered from) the contractor to be awarded the contract and sets
forth the terms and conditions that will form part of the resulting contract.
The RFP includes a description of the evaluation criteria to be used by the
procuring agency, usually focused on price, past performance and
technical/management plan. The government may unilaterally accept offers made by
contractors pursuant to an RFP without further negotiations.

    TASK ORDER--is a contract order issued by a government agency under an
umbrella contract vehicle such as an IDIQ contract. The task order is separately
priced and contains a description of services to be performed and a defined
period of performance.

         NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

                                 JUNE 30, 1999

(1) BASIS OF PRESENTATION

    The unaudited interim financial information as of June 30, 1999, and for the
six months ended June 30, 1999 and 1998, has been prepared in accordance with
generally accepted accounting principles for interim financial information. In
the opinion of management, such information contains all adjustments, consisting
only of normal recurring adjustments, considered necessary for a fair
presentation of such information. The operating results for the six months ended
June 30, 1999 may not be indicative of the results of operations for the year
ending 1999 or any future period. This financial information should be read in
conjunction with the Company's audited consolidated financial statements and
footnotes thereto.

(2) SENIOR SUBORDINATED NOTES OFFERING AND RELATED TRANSACTIONS

    On May 11, 1999, the Company completed an offering of $100 million of its
12% Senior Subordinated Notes due 2009 (the "Notes"). The Notes are unsecured
and are guaranteed by all of the Company's current and future domestic
subsidiaries. The Notes require semi-annual interest payments beginning on
November 15, 1999 through maturity on May 15, 2009. The Notes may be redeemed at
the option of the Company after May 15, 2004 upon the payment of certain
redemption premiums, although up to 25% of the Notes can be redeemed prior to
May 15, 2002 with the proceeds of certain equity offerings and upon the payment
of certain redemption premiums. The Notes contain various restrictive covenants,
including limitations on the incurrence of additional indebtedness, restrictions
and limitations on dividends paid to the Company's parent, Azimuth Technologies,
Inc., and restrictions and limitations on the sales of certain assets, among
others. The Notes also require the maintanence of certain ratios.

    Concurrent with the offering of the Notes, the Company's parent, Azimuth
Technologies, Inc., invested an additional $22.5 million in the Company's common
stock (the "Equity Contribution").

    During June 1999, the Company obtained a new bank credit facility (the "New
Credit Facility") with a syndicate of banks, which includes a revolving line of
credit (the "Revolving Credit Facility") and a term loan facility (the "Term
Loan Facility"). The Revolving Credit Facility has maximum borrowings of up to
$120 million, as determined based on a portion of eligible accounts receivable,
and bears interest at varying rates based on LIBOR plus a margin determined
using Anteon's ratio of net debt to EBITDA (as defined in the New Credit
Facility) and matures on June 23, 2005. As of June 30, 1999, the outstanding
balance on the Revolving Credit Facility was $13.0 million. The Term Loan
Facility consists of a term loan of $60 million bearing interest at varying
rates based on LIBOR plus a margin determined using Anteon's ratio of net debt
to EBITDA (as defined in the New Credit Facility). Principal payments on the
Term Loan Facility commence on a quarterly basis after June 23, 2001, with $15
million due at maturity on June 23, 2005. The New Credit Facility is secured by
substantially all of the tangible and intangible assets of Anteon and the
Guarantor Subsidiaries (see note 5).

    The proceeds from the Notes, the Equity Contribution, and the New Credit
Facility were used, along with other available cash to acquire all of the
outstanding stock of Analysis & Technology, Inc. and repay all outstanding
amounts on the Company's previous bank line of credit. Deferred financing fees
of $772 associated with the previous bank line of credit were written off during
the six months ended June 30, 1999 and have been recognized as an extraordinary
item.

(3) ACQUISITION OF ANALYSIS & TECHNOLOGY, INC.

    On June 23, 1999, the Company acquired all of the outstanding stock of
Analysis & Technology, Inc. ("A&T"), a provider of system and engineering
technologies, technology-based training systems, and information technologies to
the U.S. Government and commercial industry. The acquisition was accounted for
using the purchase method whereby the net tangible and identifiable intangible
assets acquired and liabilities assumed were recognized at their estimated fair
market values at the date of combination. These estimates were based on
preliminary appraisals and other studies that will be completed during the
remainder of 1999. Goodwill resulting from the combination is being amortized on
a straight-line basis over thirty years.

    The total purchase price paid, including transaction costs, of approximately
$115.4 million, was preliminarily allocated to the assets and liabilities
acquired as follows (in thousands):

(6) DOMESTIC SUBSIDIARIES SUMMARIZED FINANCIAL INFORMATION

subsidiaries (the "Subsidiary Guarantors") are guarantors of the Notes. Such

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors
Anteon Corporation and subsidiaries:

    We have audited the accompanying consolidated balance sheets of Anteon
Corporation (a majority-owned subsidiary of Azimuth Technologies, Inc.) and
subsidiaries (Successor) as of December 31, 1998 and 1997, and the related
consolidated statements of income, stockholders' equity and cash flows for the
years ended December 31, 1998 and 1997 and for the period from April 1, 1996 to
December 31, 1996 (Successor periods), and the statements of income,
stockholder's equity and cash flows of Ogden Professional Services Corporation
(an indirect wholly owned subsidiary of Ogden Corporation) (Predecessor) for the
period from January 1, 1996 to March 31, 1996 (Predecessor period). 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 aforementioned Successor consolidated financial
statements present fairly, in all material respects, the financial position of
Anteon Corporation and subsidiaries as of December 31, 1998 and 1997 and the
results of their operations and their cash flows for the Successor periods, in
conformity with generally accepted accounting principles. Further, in our
opinion, the aforementioned Predecessor financial statements present fairly, in
all material respects, the results of operations and cash flows of Ogden
Professional Services Corporation for the Predecessor period, in conformity with
generally accepted accounting principles.

    As discussed in Note 1 to the consolidated financial statements, effective
April 1, 1996, Azimuth Technologies, Inc. acquired all of the outstanding stock
of Ogden Professional Services Corporation in a business combination accounted
for as a purchase. As a result of the acquisition, the financial information for
the period after the acquisition is presented on a different cost basis than
that for the period before the acquisition and, therefore, is not comparable.

Supplemental disclosure of noncash investing and financing activities:

    As of September 30, 1998, the Company reached a settlement on the
    arbitration proceedings related to the purchase of the Company from Ogden
    Professional Services Corporation (note 1). The reduction of $4.85 million
    of the consideration paid for the Company was recognized as a reduction of
    the Ogden debt at the Azimuth level and the goodwill from the Anteon
    acquisition.

    In connection with the Techmatics acquisition (note 3), the Company assumed
    $10 million of subordinated notes payable discounted as of the date of
    acquisition to approximately $8,880,000. In May 1998, the Company assumed $4
    million of future income tax obligations of the former shareholders of
    Techmatics discounted to approximately $3.762 million as of the date of
    acquisition. In addition, the Company entered into two-year noncompete
    agreements valued at $2.85 million with certain executives of Techmatics
    discounted to approximately $2.654 million as of the date of acquisition.

(1) ORGANIZATION AND BUSINESS

    Anteon Corporation ("Anteon" or the "Company") was acquired by Azimuth
Technologies, Inc. ("Azimuth") (formerly CIC Technologies, Inc.) effective April
1, 1996. Azimuth acquired all of the outstanding stock of Ogden Professional
Services Corporation, a wholly owned subsidiary of Ogden Technology Services
Corporation and an indirectly wholly owned subsidiary of Ogden Corporation
(collectively, "Ogden"). Upon completion of the acquisition, Ogden Professional
Services Corporation was renamed Anteon Corporation. The consideration paid by
Azimuth to Ogden was approximately $45.2 million, consisting of approximately
$36.7 million cash and a note payable to Ogden from Azimuth for $8.5 million.
The acquisition of Anteon was accounted for using the purchase method whereby
the net tangible and identifiable intangible assets acquired and liabilities
assumed were recognized at estimated fair market value as of the date of the
combination.

    The total purchase price paid, including transaction costs, of approximately
$47.1 million was allocated to the assets and liabilities acquired as follows
(in thousands):

</TABLE>

    Subsequent to the date of the closing of the Anteon acquisition and in
accordance with the stock purchase agreement, the Company filed a demand for
arbitration against Ogden seeking refund of a portion of the purchase price. As
of September 30, 1998, the arbitration proceedings were settled and resulted in
a reduction of $4.85 million of the purchase price paid to Ogden in the 1996
acquisition of Anteon. The settlement was recognized as a reduction of the note
payable for Azimuth to Ogden and goodwill from the Anteon acquisition.

    The Company provides professional information technology, systems and
software development, high technology research, and engineering services
primarily to the U.S. government and its agencies.

    The Company is subject to all of the risks associated with conducting
business with the U.S. federal government, including the risk of contract
terminations at the convenience of the government, and including government
funding limitations.

Professional Services Corporation. The financial information for the period
after the acquisition is presented on a different cost basis than that for the
period before the acquisition and, therefore, is not comparable. All material
intercompany transactions and accounts have been eliminated in consolidation.

    The consolidated financial statements as of December 31, 1998 and 1997 also
include the assets and liabilities of Vector Data Systems, Inc. and its
majority-owned subsidiary, Vector Data Systems (U.K.) Limited, and Anteon's
wholly-owned subsidiaries, Anteon VDS-Korea (Korea) Limited and Vector Data
Systems Australia Pty. Ltd. (Australia), and their results of operations and
cash flows for the year ended December 31, 1998 and for the period August 29,
1997 to December 31, 1997, subsequent to its acquisition by the Company (see
note 3).

    The consolidated financial statements as of December 31, 1998 also include
the assets and liabilities of Techmatics, Inc. and its results of operations and
cash flows for the period May 29, 1998 to December 31, 1998, subsequent to its
acquisition by the Company (see note 3).

    (B) CASH AND CASH EQUIVALENTS

    Cash and cash equivalents include all cash balances and highly liquid
investments that have original maturities of three months or less.

    (C) INVENTORY

    Inventory consists of computer hardware and software products and is stated
at the lower of cost or market, on a first-in, first-out basis. The Company
established reserves for obsolete inventory of $500,000 and $0 as of December
31, 1998 and 1997, respectively.

    (D) PROPERTY AND EQUIPMENT

    Property and equipment is stated at cost, or fair value if acquired through
a purchase business combination. For financial reporting purposes, depreciation
and amortization is provided using the straight-line method over the estimated
useful lives of the assets as follows:

<TABLE>
<S>                                         <C>
Computer hardware and software............  3 to 5 years
Furniture and equipment...................  5 to 7 years
                                            shorter of estimated useful life or
Leasehold improvements....................  lease term
</TABLE>

    (E) INVESTMENTS

    The Company accounts for investments in debt and marketable equity
securities depending on the purpose of the investment. The Company's only
investment as of December 31, 1998 consists entirely of marketable equity
securities. Since the Company does not hold this investment principally for the
purpose of selling the investment in the near term, the Company classifies the
securities as available-for-sale. Accordingly, this investment is recognized at
fair market value and any unrealized gains (losses) are recognized as a
component of stockholders' equity. As of December 31, 1998, the aggregate fair
market value of the investments was $5,978,000, resulting in an unrealized gain
of $392,000.

                           DECEMBER 31, 1998 AND 1997

    (F) DEFERRED FINANCING COSTS

    Costs associated with obtaining the Company's financing arrangements have
been deferred and are amortized over the term of the financing arrangements
using a method that approximates the effective interest method.

    (G) IMPAIRMENT OF LONG-LIVED ASSETS AND LONG-LIVED ASSETS TO BE DISPOSED OF

    The Company follows the provisions of Statement of Financial Accounting
Standards No. 121, ACCOUNTING FOR THE IMPAIRMENT OF LONG-LIVED ASSETS AND
LONG-LIVED ASSETS TO BE DISPOSED OF ("SFAS No. 121"). This Statement requires
that long-lived assets and certain identifiable intangibles be reviewed for
impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable. Recoverability of assets to
be held and used is measured by a comparison of the carrying amount of an asset
to future net cash flows expected to be generated by the asset. If such assets
are considered to be impaired, the impairment to be recognized is measured by
the amount by which the carrying amount of the assets exceed the fair values of
the assets.

    (H) GOODWILL

    The excess of the cost over the fair value of net tangible and identifiable
intangible assets acquired in purchase business combinations (goodwill) is
amortized on a straight-line basis over periods of 20 to 30 years. The Company
evaluates the recoverability of its goodwill annually in accordance with the
provisions of SFAS No. 121.

    (I) OTHER INTANGIBLE ASSETS

    The Company amortizes, on a straight-line basis, the allocated cost of
noncompete agreements entered into in connection with business combinations.

    (J) REVENUE RECOGNITION

    The Company provides professional services under long-term contracts,
primarily with the U.S. government. Revenues for cost-reimbursement contracts
are recorded on the basis of direct and indirect costs incurred and a ratable
portion of fee. Revenues under time-and-materials contracts are recorded at the
contracted rates as the labor hours and other direct costs are incurred.
Revenues under fixed-price contracts are recognized using the
percentage-of-completion method based on costs incurred in relation to total
estimated costs. Anticipated losses on contracts are recognized as soon as they
become known. Revenues from sales of products are generally recognized upon
acceptance by the customer, which is typically within thirty days of shipment.

    (K) COSTS OF ACQUISITIONS

    Costs incurred on successful acquisitions are capitalized as a cost of the
acquisition, while costs incurred by the Company for unsuccessful or
discontinued acquisition opportunities are expensed as incurred.

                           DECEMBER 31, 1998 AND 1997

    (L) INCOME TAXES

    The Company is currently included in the consolidated income tax returns of
Azimuth. Prior to April 1, 1996, the Company was included in the consolidated
income tax returns of Ogden. However, the Company prepares its provisions for
income taxes as if it filed its income tax returns separately. The Company
calculates its income tax provision using the asset and liability method. Under
the asset and liability method, deferred income taxes are recognized for the
future tax consequences attributable to differences between the financial
statement carrying amounts and the tax bases of existing assets and liabilities.
Deferred tax assets and liabilities are measured using enacted tax rates
expected to apply to taxable income in the years in which those temporary
differences are expected to be recovered or settled. The effect on deferred
taxes of a change in tax rates is recognized in income in the period that
includes the enactment date.

    (M) FOREIGN CURRENCY TRANSLATION AND TRANSACTIONS

    The balance sheets of Vector Data Systems (U.K.) Limited, Anteon VDS (Korea)
Limited and Vector Data Systems Australia Pty. Ltd. (Australia) Limited are
translated to U.S. dollars for consolidated financial statement purposes using
the current exchange rates in effect as of year end. The revenue and expense
accounts of foreign subsidiaries are converted using a weighted average exchange
rate during the period. Gains and losses resulting from such translations are
included in accumulated comprehensive income in stockholders' equity. Gains and
losses from transactions denominated in foreign currencies are included in
current period income.

    (N) ACCOUNTING FOR DEFERRED CONTRACT COSTS

    During 1998, the Company adopted the provisions of Statement of Position No.
98-5, REPORTING ON THE COSTS OF START-UP ACTIVITIES ("SOP 98-5"), which requires
costs of start-up activities, including precontract costs, to be expensed as
incurred. During 1994 and 1995, the Company capitalized certain precontract
costs associated with two of its significant contracts (Capzone/Paczone
contracts). The remaining balances of the precontract costs were written-off
during 1998 in implementing SOP 98-5. The adoption of SOP 98-5 did not have a
material impact on the Company's financial position or results of operations.

    (O) ACCOUNTING FOR STOCK-BASED COMPENSATION

    The Company accounts for stock-based compensation plans using the intrinsic
value based method of accounting prescribed by APB Opinion No. 25, ACCOUNTING
FOR STOCK ISSUED TO EMPLOYEES; however, the Company discloses the pro forma
effect on net income as if the fair value based method of accounting as defined
in SFAS No. 123 had been applied.

    (P) FAIR VALUE OF FINANCIAL INSTRUMENTS

    The carrying amounts of accounts receivable, accounts payable and accrued
liabilities approximate their fair market values as of December 31, 1998 and
1997 due to the relatively short duration of these financial instruments. The
carrying amounts of the Company's indebtedness approximate their fair values as
of December 31, 1998 and 1997 as they bear interest rates that approximate
market.

                           DECEMBER 31, 1998 AND 1997

    (Q) USE OF ESTIMATES

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

    (R) RECLASSIFICATIONS

    Certain reclassifications have been made to the 1997 and 1996 consolidated
financial statements to conform to the 1998 consolidated financial statement
presentation.

(3) ACQUISITIONS

    (A) VECTOR DATA SYSTEMS, INC.

    On August 29, 1997, the Company acquired all of the outstanding stock of
Vector Data Systems, Inc., as well as Vector's eighty percent interest in Vector
Data Systems (UK) Limited (collectively, "Vector"). The consideration paid by
Anteon to the former shareholders of Vector was approximately $19 million in
cash financed through borrowings under an existing revolving line of credit with
a financial institution (see note 7). Additional consideration of up to $6
million may be paid by the Company and is contingent upon Vector meeting certain
revenue and gross profit thresholds for 1998 and 1999. The maximum additional
consideration that could be paid to Vector for meeting or exceeding all of the
specified thresholds would be up to $3 million per year for 1998 and 1999.
Vector did not meet the revenue and gross profit thresholds in 1998. The
acquisition of Vector was accounted for using the purchase method whereby the
net tangible and identifiable intangible assets acquired and liabilities assumed
were recognized at their estimated fair market values as of the date of the
combination. Additional consideration earned by Vector would be accounted for by
the Company as an increase of goodwill from the combination.

    The total purchase price paid, including transaction costs, of approximately
$19.5 million, was allocated to the assets and liabilities acquired as follows
(in thousands):

    (B) TECHMATICS, INC.

    On May 29, 1998, the Company acquired all of the outstanding stock of
Techmatics, Inc. ("Techmatics"), a subchapter S corporation. The consideration
paid by Anteon to the former shareholders and option holders of Techmatics was
approximately $31 million in cash, $27 million due at closing and financed
through an existing revolving line of credit with a financial institution (see
note 7), $4 million in cash payable in two non-interest bearing installments
payable no later than April 1, 1999, and $10 million in subordinated notes
payable. Additional consideration of up to $6.25 million may be paid by the
Company but is contingent upon Techmatics meeting certain operating profit
thresholds for its fiscal year ending June 30, 1999 or the year ending December
31, 1999 depending on the date chosen by Anteon. Interest at rates of 6 percent
per year and 7.5 percent per year accrue beginning September 30, 1999 and April
1, 2000, respectively, on the amount of contingent consideration to be paid
based on either the June 30, 1999 financial results or the December 31, 1999
financial results, respectively, whichever is chosen as the measurement date by
Anteon. The acquisition of Techmatics was accounted for using the purchase
method whereby the net tangible and identifiable intangible assets acquired and
liabilities assumed were recognized at their estimated fair market value as of
the date of combination. Additional consideration earned by Techmatics would be
accounted for by the Company as an increase of goodwill from the combination.

    The total purchase price paid, including transaction costs, of approximately
$40.3 million, was allocated to the assets and liabilities acquired as follows

                           DECEMBER 31, 1998 AND 1997

    In conjunction with the purchase agreement, the Company entered into
noncompete agreements for approximately $2,850,000, payable over a three-year
period and discounted to $2,654,000 as of the date of acquisition, with three
employees of Techmatics. In addition, the Company assumed certain tax
obligations of the former shareholders of Techmatics amounting to $4,000,000
payable over the two-year period ended May 31, 1999, and discounted to
$3,762,000 as of the date of acquisition.

    Techmatics also provides professional information technology, systems and
software development, high technology research, and engineering services
primarily to the U.S. government and its agencies.

    The following unaudited pro forma summary presents consolidated information

</TABLE>

    Unbilled costs and fees and retainages billable upon completion of contracts
are amounts due primarily within one year and will be billed on the basis of
contract terms and delivery schedules.

    The accuracy and appropriateness of the Company's direct and indirect costs
and expenses under its government contracts, and therefore its accounts
receivable recorded pursuant to such contracts, are subject to extensive
regulation and audit, including by the U.S. Defense Contract Audit Agency
("DCAA") or by other appropriate agencies of the U.S. government. Such agencies
have the right to challenge the Company's cost estimates or allocations with
respect to any government contract. Additionally, a substantial portion of the
payments to the Company under government contracts are provisional payments that
are subject to potential adjustment upon audit by such agencies. In the opinion
of management, any adjustments likely to result from inquiries or audits of its
contracts would not have a material adverse impact on the Company's financial
condition or results of operations.

(7) INDEBTEDNESS

    (A) BANK LOAN AGREEMENT

    Concurrent with the Anteon acquisition, the Company entered into a Business
Loan and Security Agreement (the "Bank Loan Agreement") with two commercial
banks. Under the terms of the Bank Loan Agreement, the Company entered into
promissory notes for an aggregate available financing facility of $38 million.
Concurrent with the Vector acquisition, the Bank Loan Agreement was amended (the
"Amended Bank Loan Agreement") whereby the financial institution increased the
promissory notes by $6 million for an aggregate available facility of $44
million. The facility was comprised of revolving promissory notes for aggregate
borrowings of up to $22 million based on a portion of eligible billed accounts
receivable (Facility A); revolving promissory notes for aggregate borrowings of
up to $16 million based on a portion of eligible unbilled accounts receivable
(Facility B); and term promissory notes for an aggregate of $6 million (Facility
C). The available facility limits on the Facility A and Facility B promissory
notes were approximately $17,760,000 and $10,860,000, respectively, as of
December 31, 1997. As of March 18, 1998, this Bank Loan Agreement was terminated
and replaced by a $125 million Credit Agreement as discussed below.

    Prior to the Vector acquisition, interest on Facility A accrued at either
the prime rate plus 0.25 percent or the LIBOR Rate plus 2.5 percent. Under the
Amended Bank Loan Agreement, the interest rate on Facility A varied based on the
Company's ratio of debt to earnings before income taxes, depreciation and

amortization, calculated quarterly. Interest was payable on a quarterly basis.
During the years ended December 31, 1998 and 1997, interest on Facility A ranged
from 8.13 percent to 8.75 percent and 7.19 percent to 8.75 percent,
respectively. For the period April 1, 1996 through December 31, 1996, the
interest rate ranged from 8.03 percent to 8.5 percent.

    Facility B accrued interest at either the prime rate plus 0.75 percent or

rates charged on Facility B ranged from 9.0 percent to 9.25 percent and 9.0
percent to 9.25 percent, respectively, during the years ended December 31, 1998
and 1997 and from 8.53 percent to 9.0 percent for the period from April 1, 1996
to December 31, 1996.

    Facility C accrued interest at either the prime rate plus 1.25 percent or
the LIBOR rate plus 3.5 percent and was payable on a quarterly basis. Principal
amounts were due in equal quarterly installments of $500,000. Beginning in April
1997, additional principal amounts could also be due on the Facility C
promissory notes based on certain excess eligible billed accounts receivable
and/or excess cash flows, as defined in the Amended Bank Loan Agreement. No such
additional principal amounts became due during 1998 or 1997. Interest rates
charged on Facility C ranged from 9.22 percent to 9.75 percent and 9.0 percent
to 9.25 percent, respectively, during the years ended December 31, 1998 and 1997
and from 9.03 percent to 9.5 percent for the period from April 1, 1996 to

    Total interest expense incurred on these financial arrangements was
approximately $1,079,000 and $1,891,000, respectively, for the years ended
December 31, 1998 and 1997 and $1,382,000 for the period from April 1 1996 to
December 31, 1996 to December 31, 1996. Upon termination of this Bank Loan
Agreement, all principal and interest due on the existing Facilities A, B and C
was paid in full.

    The bank notes were secured by certain assets of the Company and certain
assets of Vector. Vector's security interest was limited to its obligations
under these bank notes. The terms of the Amended Bank Loan Agreement restricted
the ability of the Company to pay dividends, although the Company could have
declared dividends payable to Azimuth in order for Azimuth to pay required
interest payments on certain of its long-term debt.

    During 1997, the Company wrote off the remaining balance of deferred
financing costs of approximately $522,000 upon the effective date of the Amended
Bank Loan Agreement. This amount is recorded in interest expense in the
consolidated statement of income for the year ended December 31, 1997.

    (B) CREDIT AGREEMENT

    On March 18, 1998, the Company entered into a Credit Agreement (the "Credit
Agreement") with six commercial banks. Under the terms of the Credit Agreement,
the Company entered into promissory notes for an aggregate available financing
facility of $125 million. The new credit facility is comprised of a

                           DECEMBER 31, 1998 AND 1997

revolving credit facility for aggregate borrowings of up to $75 million, based
on a portion of eligible billed accounts receivable and a portion of eligible
unbilled accounts receivable (Revolving Facility); and an acquisition credit
facility for aggregate borrowings of up to $50 million (Acquisition Facility).
The Revolving Facility and the Acquisition Facility both mature on March 18,
2003.

    Under the Credit Agreement, the interest rate on the Revolving Facility
varies based on Anteon's ratio of debt to earnings before income taxes,
depreciation and amortization, calculated quarterly. Interest is payable on a
quarterly basis. During the year ended December 31, 1998, interest on the
Revolving Facility ranged from 7.8125 percent to 8.75 percent.

    The interest rate on the Acquisition Facility varies using a
performance-based interest rate schedule measured using the Company's ratio of
debt-to-earnings before income taxes, depreciation and amortization and is
calculated quarterly. Interest is payable on a quarterly basis. Interest rates
charged on the Acquisition Facility ranged from 7.5 percent to 9.25 percent
during the year ended December 31, 1998.

    As of December 31, 1998, the outstanding amounts under the Credit Agreement
are as follows (in thousands):

</TABLE>

    The remaining available facility limits on the Revolving Facility and
Acquisition Facility promissory notes were approximately $11.8 million and $15
million, respectively, as of December 31, 1998.

    Total interest expense incurred on the Revolving and Acquisition Facilities
arrangements for the year ending December 31, 1998 was approximately $3,475,000.

    The Revolving Facility is secured by certain assets of the Company and
certain assets of its subsidiaries. The subsidiaries' security interest is
limited to its obligations under these bank notes. The terms of the Credit
Agreement restrict the ability of the Company to pay dividends, although Anteon
may declare dividends payable to Azimuth in order to pay required payments on
certain of its long-term debt.

    Deferred financing costs of approximately $874,000 relating to the Credit
Agreement are included in other assets in the accompanying consolidated balance
sheet as of December 31, 1998.

    (C) SUBORDINATED NOTES PAYABLE

    In connection with the purchase of Techmatics, the Company entered into
subordinated promissory notes with the Techmatics shareholders and option
holders as of the date of acquisition in the principal amount of $10,000,000,
discounted as of the date of acquisition to approximately $8,880,000.

    The notes are to be paid in two installments with one-tenth of the total
amount payable due May 31, 1999 and the remaining nine-tenths due May 31, 2000.
Interest accrues beginning May 31, 1999 at 6 percent per year on four-ninths of
the principal amount outstanding. All overdue amounts accrue interest at 7.5
percent per year.

    This debt is subordinate to the $125 million Credit Agreement.

    (E) INTEREST RATE SWAP AGREEMENTS

    The Company has entered into interest rate swap agreements to reduce the
impact of changes in interest rates on its Credit Agreement. At December 31,
1998, the Company had outstanding interest rate swap agreements with commercial
banks having a total notional principal amount of $15 million. Those swap
agreements effectively changed the Company's interest rate exposure for $5
million based on a May 1998 swap agreement, $5 million based on a June 1998 swap
agreement, and $5 million based on a September 1998 swap agreement on its $125
million Credit Agreement due March 13, 2003 to fixed rates of 5.8 percent, 5.75
percent and 5.02 percent, respectively. The interest rate swap agreements mature
as of December 31, 2002, December 31, 2003 and September 25, 2003, respectively.
The differential to be paid or received is accrued as interest rates change and
is recognized over the life of the agreements. The Company is exposed to credit
loss in the event of nonperformance by the other parties to the interest rate
swap agreements; however, the Company does not anticipate nonperformance by the
counterparties.

    In assessing the realizability of deferred tax assets, management considers
whether it is more likely than not that some portion or all of the deferred tax
asset will be realized. The ultimate realization of the deferred tax asset is
dependent upon the generation of future taxable income during the periods in
which temporary differences become deductible. Management considers scheduled
reversals of deferred tax liabilities, projected future taxable income, and tax
planning strategies that can be implemented by the Company in making this
assessment. Based upon the level of historical taxable income, scheduled
reversal of deferred tax liabilities, and projections of future taxable income
over the periods in which the temporary differences become deductible based on
available tax planning strategies, management presently believes that it is more
likely than not that the Company will realize all of the benefits of these
deductible differences and, accordingly, has established no valuation allowance
against the deferred tax assets as of December 31, 1998 or 1997.

(9) EMPLOYEE BENEFIT PLANS

    Employees of the Company may participate in 401(k) retirement savings plans,
whereby employees may elect to make contributions pursuant to a salary reduction
agreement upon meeting eligibility requirements. Participants may contribute up
to 15 percent of salary in any calendar year to these Plans, provided that
amounts in total do not exceed certain statutory limits. The Company matches up
to 50 percent of the first 6 percent of a participant's contributions subject to
certain limitations. The Company made contributions to these plans of
approximately $1,995,000, $1,207,000, $819,000, and $282,000 for the years ended
December 31, 1998 and 1997, and the periods from April 1, 1996 to December 31,
1996 and January 1, 1996 to March 31, 1996, respectively.

    Effective January 1, 1999, a defined contribution plan previously
established at the subsidiary level was merged into the Anteon plan.

    Techmatics sponsors a defined health and welfare plan that provides health,
dental and short-term disability benefits for all eligible full-time employees
of Techmatics. The plan is self-insured and has specific employee stop-loss
coverage insurance of $50,000 and aggregate stop-loss coverage insurance which
is calculated based on monthly participation in the plan. Contributions to the
plan are made by both Techmatics and the employees and are maintained in a trust
fund intended to qualify as a tax-exempt Voluntary Employees' Beneficiary Trust
within the meaning of Section 501(c)(9) of the U.S. Internal Revenue Code.
Contributions by Techmatics are based upon estimates and on actual amounts of
claims processed. From the date of acquisition of Techmatics by the Company to
December 31, 1998, Techmatics made contributions to the plan of approximately
$879,000.

(10) EMPLOYEE STOCK OPTION PLAN

    In February 1997, the Board of Directors approved the adoption of the Anteon
Corporation Omnibus Stock Plan (the Plan). At the discretion of the Board of
Directors, the Plan permits the granting of stock options, stock appreciation
rights, restricted or unrestricted stock awards, and/or phantom stock to
employees or directors of the Company. As of December 31, 1998, an aggregate of
325,000 shares of Anteon's common stock was reserved for issuance under the
Plan.

    The exercise price of stock options granted is determined by the Board of
Directors but is not to be less than the fair value of the underlying shares of
common stock at the grant date.

    For stock options granted to employees, 20 percent of the shares subject to
the options vest on the first anniversary of the grant date and an additional 20
percent vest on each succeeding anniversary of the grant date. The employees
have a period of three years from the vesting date to exercise the option to
purchase shares of the Company's common stock. In 1997, the Board of Directors
approved that 20 percent of the options issued on the August 1, 1997 grant date
vest immediately.

    For stock options granted to directors of the Company, 33 1/3 percent of the
shares subject to the options vest on the first anniversary of the grant date
and an additional 33 1/3 percent vest on the two succeeding anniversaries of the
grant date. The directors have a period of two years from the vesting date to
exercise the option to purchase shares of the Company's common stock.

    During 1998 and 1997, the Company granted stock options under this Plan for
151,450 and 171,630 shares, respectively, of the Company's common stock at
exercise prices ranging from $26.90 per share to

    The Company applies APB No. 25 and related interpretations in accounting for
the Plan. Adoption of the fair market value provisions prescribed in SFAS No.
123 is optional with respect to stock-based compensation to employees; however,
pro forma disclosures are required as if the Company adopted the fair value
recognition requirements under SFAS No. 123.

    Had compensation cost for the Company's 1998 and 1997 grants under the Plan
been determined consistent with the fair market value provisions prescribed in
SFAS No. 123, the Company's pro forma net income for the years ended December
31, 1998 and 1997 would approximate $2,224,000 and $1,586,000, respectively,
using an expected option life of 7 years, dividend yield rate and volatility
rate of 0 percent, respectively, and a risk-free interest rate of 4.73 and 5.77
percent, respectively. The effects of applying SFAS No. 123 in this pro forma
disclosure are not indicative of future amounts.

(11) COMPREHENSIVE INCOME

    During 1998, the Company adopted the provisions of Statement of Financial
Accounting Standards No. 130, REPORTING COMPREHENSIVE INCOME ("SFAS No. 130").
SFAS No. 130 requires the display of comprehensive income, which includes the
Company's unrealized gains (losses) on investments and the accumulated foreign
currency translation adjustment. The Company has presented comprehensive income
as a component of the accompanying consolidated statements of stockholders'
equity. There were no unrealized gains (losses) on investments as of December
31, 1997 or 1996. During the year ended December 31, 1998, $392,000 of
unrealized gains on investments was recognized. The amount of accumulated
foreign currency translation adjustment was approximately $7,000 and $0 as of
December 31, 1998 or 1997, respectively.

(13) DOMESTIC SUBSIDIARIES SUMMARIZED FINANCIAL INFORMATION

    As of April 1999, the Company is contemplating participating in a private
debt offering for up to $120,000,000 in Senior Subordinated Notes (the "Notes").
Under the current structure of the Notes, the Company's wholly-owned domestic
subsidiaries would be guarantors (the "Subsidiary Guarantors") of the Notes.
Such guarantees are full, unconditional and joint and several. Separate
financial statements of the Subsidiary Guarantors are not presented because the
Company's management has determined that they would not be material to
investors. The following supplemental financial information sets forth, on a
combined basis, balance sheets, statements of operations and statements of cash
flows information for the Subsidiary Guarantors, the Company's non-guarantor
subsidiaries and for the Company.

              NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

                                 MARCH 31, 1998

NOTE 1--UNAUDITED INTERIM FINANCIAL INFORMATION

    The unaudited consolidated balance sheet, statements of earnings and cash
flows as of March 31, 1998 and for the nine months ended March 31, 1998 and 1997
have been prepared in accordance with generally accepted accounting principles
for interim financial information. In the opinion of management, all adjustments
(consisting of normal recurring accruals) considered necessary for a fair
presentation have been included. Operating results for the interim period are
not necessarily indicative of the results that may be expected for any future
period, including the year ending June 30, 1998.

NOTE 2--INCOME TAXES

    Through March 31, 1998, the Company continued its election to be treated as
an S Corporation for federal and certain state income tax purposes. Accordingly,
the accompanying unaudited consolidated statements of earnings show no provision
for federal income taxes. State income taxes in those states that do not
recognize the Company's S Corporation status were not significant.

NOTE 3--SUBSEQUENT EVENT--DISCONTINUED OPERATIONS OF TECHMATICS INFORMATION
ALLIANCE AND COMMUNICATIONS (TIAC)

    On July 1, 1997, the Company adopted a formal plan to discontinue the
operations of Techmatics Information Alliance and Communications (TIAC). TIAC
was a provider of information services to commercial customers, principally
related to the Internet. Certain assets were sold for cash to an unrelated third
party. Other assets were liquidated in the ordinary course of business. Assets
disposed of consisted primarily of accounts receivable, supplies and equipment.

    The results of operations of TIAC for the nine months ended March 31, 1997
have been reported as discontinued operations. Net sales for TIAC for the nine
months ended March 31, 1998 and 1997 were $0 and approximately $690,000,
respectively.

NOTE 4--SUBSEQUENT EVENT

    Effective May 29, 1998, all of the Company's outstanding common stock was
acquired by Anteon Corporation, a privately-held company that provides
professional services primarily to the U.S. Government and its agencies.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

Board of Directors
TECHMATICS, Inc.

    We have audited the accompanying consolidated balance sheet of TECHMATICS,
Inc., and subsidiary as of June 30, 1997, and the related consolidated
statements of income, changes in stockholders' equity and cash flows for the
year then ended. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audit.

    We conducted our audit 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 audit provides a reasonable basis for our opinion.

    In our opinion, the consolidated financial statements referred to above,
present fairly, in all material respects, the financial position of TECHMATICS,
Inc., and subsidiary as of June 30, 1997, and the results of its operations and
its cash flows for the year then ended in conformity with generally accepted
accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                 JUNE 30, 1997

NOTE A--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NATURE OF OPERATIONS

    TECHMATICS, Inc. (the Company), was incorporated March 15, 1982, under the
laws of the Commonwealth of Virginia for the purpose of engaging in a consulting
business. The Company specializes in engineering, management, and information
technology services primarily for agencies of the U.S. government. Services are
also provided to commercial enterprises.

PRINCIPLES OF CONSOLIDATION

    The accompanying consolidated financial statements include the accounts of
TECHMATICS, Inc., and its wholly owned subsidiary. Material intercompany
accounts and transactions have been eliminated.

REVENUE FROM CONTRACTS

    Most of the Company's revenue is generated from cost-plus fixed fee level of
effort contracts, which require the Company to perform agreed-upon amounts of
labor hours within specified categories and skill levels. In return, the Company
receives reimbursement of its direct and indirect costs of contract performance,
within stipulated limits, plus a negotiated fixed fee representing the Company's
gross profit. Revenue derived from this type of contract totaled 86% of revenue
for fiscal year 1997 and is recognized on the basis of reimbursable costs
incurred plus a pro rata portion of fees earned.

    Revenue on time-and-materials contracts totaled 6% of revenue for fiscal
year 1997 and is recognized on the basis of direct-labor hours and reimbursable
materials costs incurred. Revenue on fixed-price contracts totaled 8% of revenue
for fiscal year 1997 and is recorded on the percentage-of-completion method
based upon costs incurred in relation to total estimated costs. Losses are
recorded in full when determinable.

PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost. Expenditures for maintenance,
repairs, and improvements which do not materially extend the useful lives of
assets are expensed as incurred. The Company depreciates its property and
equipment using primarily the straight-line method based on estimated useful
lives of assets. Certain computer equipment is depreciated using accelerated
methods. Leasehold improvements are amortized over the shorter of the terms of
the respective leases or the estimated useful lives. Estimated useful lives of
property and equipment and leasehold improvements are as follows:

<TABLE>
<S>                                           <C>
Computer equipment..........................  3-5 years
Furniture and equipment.....................  4-5 years
                                              Lesser of lease term or useful
Leasehold improvements......................  life
Real property...............................  30 years
</TABLE>

INCOME TAXES

    The accompanying consolidated financial statements are presented on the
accrual basis of accounting, which recognizes income when earned and recognizes
costs and expenses when incurred, as required by generally accepted accounting
principles. However, for tax reporting purposes, the Company computes its

                                TECHMATICS, INC.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

                                 JUNE 30, 1997

NOTE A--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
income or loss on the cash basis, wherein income is recognized when collected in
cash, and costs and expenses are recognized as cash is paid.

    The Company has elected S corporation status for federal and certain state
income tax purposes. Under such election, the taxable income or loss of the
Company is apportioned among the Company's stockholders, based upon their
percentage of ownership during the year, and included in the individual tax
returns of the stockholders. Therefore, the accompanying consolidated statement
of earnings shows no provision by the Company for federal income taxes. For the
year ended June 30, 1997, the Company has recorded a provision of $29,278, for
income taxes, in certain states that do not recognize the Company's S status or
in which the Company chose not to elect S status.

    The Company intends to terminate its S election effective January 1, 1998.
If the Company had elected to terminate the S status at June 30, 1997, the
Company would have recorded a one-time charge against income from continuing
operations of approximately $4,000,000. The charge will reflect a deferred
income tax liability arising as a result of cumulative differences between
financial statement and income tax reporting, principally relating to the
adjustments from the accrual method to the cash method of accounting.

USE OF ESTIMATES IN PREPARING FINANCIAL STATEMENTS

    In preparing financial statements in conformity with generally accepted
accounting principles, management is required to make estimates and assumptions
that affect the reported amounts of assets and liabilities and the disclosure of
contingent assets and liabilities at the date of the financial statements and
revenue and expenses during the reporting period. Loss on discontinued
operations of the subsidiary (see Note C) includes estimated costs to dispose of
the subsidiary during the phase-out period, net of any income tax benefits
resulting from the discontinuance of operations. Actual results could differ

    At June 30, 1997, the Company's carrying value of financial instruments
approximated fair value. Carrying amounts for accounts receivable, notes
receivable, accounts payable, line of credit and deferred income taxes
approximate fair value because of the short maturity of such instruments.

NOTE B--UNBILLED ACCOUNTS RECEIVABLE

    Unbilled accounts receivable represent revenue recognized for work performed
but not billed at year-end. Unbilled amounts at June 30, 1997, are expected to
be billed in 1997 and thereafter. Amounts

NOTE C--INVESTMENT IN AFFILIATE

    In May 1995, the Company formed TECHMATICS Information Alliance and
Communications (TIAC), a Virginia limited liability company. TIAC provides
customers with information services, principally related to the Internet. The
Company invested $100,000 in the purchase of a 78% interest in TIAC, and agreed
to advance working capital funds as required by TIAC. In accordance with
generally accepted accounting principles, a minority interest in TIAC is not
recorded, as losses related to the minority interest exceed its equity in TIAC.

    On July 1, 1997, the Company adopted a formal plan to discontinue the
operations of TIAC. On August 31, 1997, the Company disposed of TIAC. Assets
disposed of consisted primarily of accounts receivable; supplies; and property,
plant and equipment.

    As of August 8, 1997, the operations are in the process of termination.
Certain assets were sold for cash to an unrelated third party. The remaining
assets and liabilities are being liquidated in the normal course of business.

    The Company had guaranteed a lease for space in which TIAC conducted its
operations. The remaining obligations under the original terms of the lease are
approximately $478,000, payable monthly through February 28, 2001. The Company
has entered into a sublease for the space and has recognized a loss of
approximately $118,000, representing the difference between the Company's
obligation on the lease and the estimated future income from the sublease.

    Additionally, in connection with the discontinuation of operations and
resulting employment terminations, the Company has accrued $155,000 of severance
pay.

    The loss arising from the discontinued operations is $786,596 (net of income
tax benefit of $9,385) representing the loss on sale and liquidation of assets
of TIAC, and a provision of $149,459 for operating losses during the phase-out
period from July 1, 1997, through August 31, 1997.

NOTE G--COMMITMENTS AND CONTINGENCIES

CONTRACTS

    Substantially all payments to the Company under cost-reimbursable contracts
and subcontracts are provisional reimbursements of claimed cost and the pro rata
portion of the fixed fee thereon. Eligibility of the costs for reimbursement is
subject to annual audits by the DCAA. Audits of fiscal years 1994 through 1996
have not been finalized, and the audit of fiscal year 1997 has not yet begun.

    Management believes resolution of the audits will have no material effect
upon the financial position of the Company or the results of future operations.

LEASE COMMITMENTS

NOTE G--COMMITMENTS AND CONTINGENCIES (CONTINUED)
    The Company subleases part of its office space to a related party under a
sublease agreement. Rent expense totaled $2,742,228 for 1997.

NOTE H--BENEFIT PLANS

    Eligible employees of the Company may participate in a 401(k) savings plan
whereby employees may elect to make contributions pursuant to a salary reduction
agreement upon meeting age and length-of-service requirements. The directors, at
their discretion, elected to contribute to the 401(k) savings plan approximately
$436,000 for the plan year ended December 31, 1996. The Company accrued a
liability of approximately $281,000 for the period from January 1, 1997, through
June 30, 1997.

    The Company has adopted a deferred compensation plan which provides
retirement and death benefits to certain officers of the Company. The plan is
funded by split-dollar life insurance policies for which the Company makes the
payments. In return, the officer, who is the owner of the policy, assigns
certain rights in the policy to secure the payments made by the Company, and the
Company is to receive a return of its funds before other benefits are paid.
Accordingly, the Company has recorded deposits of $1,115,000 at June 30, 1997.

    The Company expects to pay out the amount of the deposits, when returned by
the insurance company in the future, to the officers covered as deferred
compensation, and intends to fund the plan for the required number of years. In
the event the Company were to discontinue funding the plan, some or all the
deposit may not be realized, depending on the cash surrender value of the
policies. The cash surrender value of the policies at June 30, 1997, was
$664,800.

    The plan premium paid by the Company is recorded as a deposit with a
corresponding deferred compensation liability recorded at the present value of
the future benefits to be paid by the Company. In computing the present value of
the future benefits, the discount rate used is equal to the interest rate as
determined by the Secretary of the Treasury at fiscal year-end. At the end of
the plan period, the aggregate amount accrued will be equal to the present value
of the benefits expected to be provided to the employees.

    The plan premiums of $228,000 were paid for the year ended June 30, 1997.
The deferred compensation liability accrued was $1,115,000 for the year ended
June 30, 1997.

NOTE I--RELATED PARTY TRANSACTIONS

    The Company leases office space to a corporation, the owner of which is a
director of the Company. Total lease payments received under the lease amounted
to approximately $44,000 in 1997. Sublease income received by the Company is
recorded as a reduction to rent expense. The Company also has various contracts
and subcontracts with the same corporation. Costs paid to the related party
totaled approximately $372,200 in 1997.

    The Company has a computer purchase program under which it makes
noninterest-bearing loans between $500 and $3,000 to employees for the purchase
of computer equipment and related items. The loans are repayable through payroll
deduction over a maximum of three years. As of June 30, 1997, aggregate
outstanding balances of such loans totaled approximately $231,600. The amount
currently due is included in "notes receivable from employees" and the long-term
portion is included in "other assets" in the accompanying balance sheet.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                          AS OF JUNE 30, 1996 AND 1995

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

ORGANIZATION

    TECHMATICS, Inc. (the "Company"), was incorporated on March 15, 1982, under
the laws of the Commonwealth of Virginia for the purpose of engaging in a
consulting business. The Company specializes in engineering, management and
information technology services for the United States Navy and other customers.

REVENUES FROM CONTRACTS

    The preponderance of the Company's revenue is generated from cost-plus fixed
fee contracts. This type of contract provides for the Company to perform
agreed-upon numbers of labor hours within specified categories and skill levels.
In return, the Company receives reimbursement of its direct and indirect costs
of contract performance, within stipulated limitations, plus a negotiated fixed
fee that represents the Company's gross profit. Revenue derived from this type
of contract, 89 and 91 percent of total revenue for fiscal years 1996 and 1995,
respectively, is recognized on the basis of reimbursable costs incurred plus a
pro rata portion of fees earned.

    Revenue on time-and-material contracts (9 and 8 percent of total revenue for
fiscal years 1996 and 1995, respectively) is recognized on the basis of
direct-labor hours and reimbursable materials costs incurred. Revenue on
fixed-price contracts (2 and 1 percent of total revenue for fiscal years 1996
and 1995, respectively) is recorded on the percentage-of-completion method based
upon costs incurred in relation to total estimated costs. Losses are recorded in
full when they become determinable.

    In 1995, one of the Company's U.S. government contracts represented 11
percent of total revenues.

PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost. Expenditures for maintenance,
repairs and improvements which do not materially extend the useful lives of the
assets are expensed as incurred. The Company depreciates its property and
equipment primarily using the straight-line method based on the estimated useful
lives of the assets. Certain computer equipment is depreciated using accelerated
methods. Leasehold improvements are amortized over the shorter of the terms of
the respective leases or the estimated useful lives. Estimated useful lives of
property and equipment and leasehold improvements are as follows:

<TABLE>
<S>                                   <C>
Computer equipment..................  3-5 years
Furniture and equipment.............  4-5 years
                                      Lesser of lease term or useful
Leasehold improvements..............  life
Real property.......................  30 years
Automobiles.........................  5 years
</TABLE>

INCOME TAXES

    The accompanying financial statements are presented on the accrual basis of
accounting. This method recognizes income when earned and recognizes costs and
expenses when incurred, as is required by generally accepted accounting
principles. For tax reporting purposes, however, the Company computes its income
or loss on the cash basis, wherein income is recognized when collected in cash
and costs and expenses are recognized as cash is paid therefor.

                                      F-59

                        TECHMATICS, INC. AND SUBSIDIARY

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

                          AS OF JUNE 30, 1996 AND 1995

    The Company has elected to be treated as a "Subchapter S" corporation for
Federal and state income tax purposes. Under this election, the taxable income
or loss of the Company for fiscal year is apportioned among the Company's
stockholders, based upon their percentage ownership during the year, and
included in the individual tax returns of the stockholders. For this reason, the
accompanying Consolidated Statement of Income shows no provision by the Company
for Federal income taxes. For fiscal years 1996 and 1995, the Company has
recorded a $10,554 and $32,484 provision, respectively, for state income taxes,
because certain states do not recognize the Company's "Subchapter S" corporation
status.

    Differences existing between net income for financial reporting purposes and
for income tax purposes are caused primarily by the use of the cash versus
accrual method of accounting and accelerated depreciation methods for tax
purposes.

SHORT-TERM INVESTMENTS

    Short-term investments consist primarily of U.S. Treasury Bills and are
stated at market which was identical to cost at June 30, 1996. In accordance
with Statement of Financial Accounting Standards No. 115, "Accounting for
Certain Investments in Debt and Equity Securities," the investments are
classified as available-for-sale at year-end. There were no significant realized
or unrealized gains or losses on these investments during the year.

USE OF ESTIMATES

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

FAIR VALUE OF FINANCIAL INSTRUMENTS

    At June 30, 1996 and 1995, the Company's carrying value of financial
instruments approximated fair value. Carrying amounts for accounts receivable,
notes receivable, accounts payable, line of credit and deferred income taxes
approximated fair value due to the short maturity of these instruments.

</TABLE>

    Certain unbilled receivables are not billable until a review of costs
incurred is performed by the Defense Contract Audit Agency (the "DCAA," see Note
6). The amounts included in unbilled accounts receivable which are expected to
be collected within a year equal $476,359 and $1,030,320 at June 30, 1996 and
1995, respectively.

3. INVESTMENT IN AFFILIATE:

    In May 1995, the Company formed a Virginia Limited Liability Company named
"Techmatics Information Alliance and Communications, LLC" (the "LLC"). The LLC
was formed to provide its customers with information services, principally
related to the Internet. The Company invested $100,000 in the purchase of a 78%
interest in the LLC and agreed to advance working capital funds as required by
the LLC. In accordance with generally accepted accounting standards, a minority
interest in the LLC is not recorded, as losses related to the minority interest
exceeded its equity in the LLC. See Note 10 for discontinued operations
discussion.

4. ACCRUED EXPENSES:

    Accrued expenses consist of the following at June 30:

                          AS OF JUNE 30, 1996 AND 1995

5. LINE OF CREDIT AND BANKING ARRANGEMENTS:

    The Company has a $8,000,000 bank line-of-credit agreement. The principal is
payable upon demand and interest is calculated using the 30 day LIBOR rate plus
225 basis points and are collateralized by accounts receivable. As of June 30,
1996, the Company had not drawn on the line-of-credit.

    The Company's principal disbursing accounts are maintained on a zero-balance
basis, wherein the bank invests any balances on hand at the close of a business
day in short-term securities. In the event that checks presented for payment
exceed available balances, the bank advances necessary funds pursuant to the
line-of-credit agreement described in the preceding paragraph. As of June 30,
1996, the Company had issued checks in the aggregate amount of approximately
$1,676,000, which had not been presented for payment; the corresponding amount
as of June 30, 1995, was $2,218,000. These amounts are classified as accounts
payable in the accompanying balance sheet for each of the respective dates.

6. COMMITMENTS AND CONTINGENCIES:

CONTRACTS

    Substantially all payments to the Company under cost-reimbursable contracts
and subcontracts are provisional reimbursements of claimed cost and the pro rata
portion of fixed fee thereon. Eligibility of these costs for reimbursement is
subject to annual audits by the DCAA. The audits through June 30, 1989, have
been finalized. Audit procedures for fiscal years 1990 through 1993 have been
completed by the DCAA and the results thereof are in the process of negotiation
and final settlement between the Company and the government. Audits of fiscal
years 1994 through 1996 costs have not as yet begun.

    Management believes that resolution of these audits will not have a material
effect upon the financial position of the Company or the results of future
operations.

LEASE COMMITMENTS

    The Company is obligated as lessee under certain noncancelable operating
leases, primarily for the office space required by its Northern Virginia
headquarters and principal operating locations.

    Future minimum rent payments required under such leases are as follows:

</TABLE>

    The leases for office space allow for annual rent adjustments based on the
change in the U.S. Consumer Price Index and additional rent assessments as
specified in the lease terms.

    The Company subleases part of its office space to a related party under a
sublease agreement. See Note 9 for sublease income received by the Company for
1996 and 1995.

    Rent expense for all operating leases, net of sublease payments, totaled
$2,442,844 and $2,338,829 in 1996 and 1995, respectively.

7. STOCKHOLDERS' EQUITY AND STOCK OPTIONS:

STOCK OPTIONS

    The Company has an employee stock option plan for key employees. It was
adopted in 1993, replacing a similar plan that had previously been in effect
since 1989. The shares optioned under both the 1989 and the 1993 plan are
nonvoting common stock, par value of $0.01 each. The 1993 plan provides for the
issuance of a maximum of 1,300,000 shares.

8. 401(K) SAVINGS PLAN:

    Eligible employees of the Company may participate in a 401(k) savings plan,
whereby the employees may elect to make contributions pursuant to a salary
reduction agreement upon meeting age and length-of-service requirements. The

has various contracts and subcontracts with this same corporation. Costs paid to
this related party were approximately $225,370 and $736,000 in 1996 and 1995,
respectively.

    The Company has a computer purchase program, under which it makes
noninterest bearing loans of between $500 and $3,000 to employees for the
purchase of computer equipment and related items. These loans are repayable
through payroll deduction over a maximum of three years. As of June 30, 1996,
the aggregate outstanding balance of such loans was approximately $207,000 and
at June 30, 1995, it was approximately $230,000. The amount currently due is
included in "notes receivable from employees" and the long-term portion is
included in "other assets" in the accompanying balance sheet.

10. SUBSEQUENT EVENT:

    On July 1, 1997, the Company adopted a formal plan to discontinue the
operations of the LLC. The LLC is a provider of information services to
commercial customers (not governmental contractors) and constitutes a separate
business segment of the Company. Certain assets were sold for cash to an
unrelated party. Other assets were liquidated in the ordinary course of
business. Assets disposed of consisted primarily of accounts receivable,
supplies and equipment.

    Net sales for the LLC for fiscal years 1996 and 1995 were approximately
$300,000 and $0, respectively. The accompanying consolidated statement of income
reflects the discontinued operations for fiscal year 1996 in order to be
comparable to the fiscal year 1997 presentation.

The Board of Directors and Shareholders
Analysis & Technology, Inc. and Subsidiaries:

    We have audited the accompanying consolidated balance sheets of Analysis &
Technology, Inc. and Subsidiaries as of March 31, 1999 and 1998, and the related
consolidated statements of earnings, changes in shareholders' equity, and cash
flows for each of the years in the three-year period ended March 31, 1999. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.

    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Analysis &
Technology, Inc. and Subsidiaries as of March 31, 1999 and 1998 and the results
of their operations and their cash flows for each of the years in the three-year

(1) DESCRIPTION OF BUSINESS, ACQUISITIONS, AND DIVESTITURES

    Analysis & Technology, Inc. (A&T) initially provided tactical analysis to
the Office of Naval Research and sonar analysis to the Naval Underwater Systems
Center, now known as the Naval Undersea Warfare Center. During the past 30
years, A&T and Subsidiaries (the Company) have grown to provide system and
engineering technologies, technology-based training systems, and information
technologies for the military, civil government agencies, and private industry.
The Company has the following wholly-owned subsidiaries:

    - Interactive Media Corp. (Interactive Media) which designs and implements
      training programs for commercial and government customers;

    - Analysis & Technology Australia Pty. Ltd. which provides training systems
      and software development services in Australia. Analysis & Technology
      International Corporation and Numerical Decisions, Inc. are subsidiaries
      formed by the Company to perform international work but are not currently
      operational.

    The Company typically performs its Department of Defense services under cost
reimbursement contracts whereby the U.S. Government reimburses the Company for
contracted costs and pays a fee. In fiscal 1999, 1998, and 1997, the amount of
the Company's non-defense revenue was $34.6 million, $30.1 million, and $23.7
million, respectively.

    The Company has made the following acquisitions accounted for as purchases:

    On September 30, 1998, the Company acquired certain assets of Information

years.

    On November 14, 1997, the Company acquired all of the stock of UP, Inc.
("UP") of Herndon, Virginia, for $5.3 million in cash plus related expenses. UP
provides technology-based interactive multimedia training to clients in
telecommunications, financial services and other industries. UP was merged into
Interactive Media upon acquisition. During fiscal 1999, under the terms of the
UP purchase agreement, the Company made a contingent payment to the former
owners of UP of $1.6 million. Goodwill totaling $6.3 million was recorded in
connection with this acquisition and is being amortized over 20 years. In

</TABLE>

    On July 18, 1997, the company sold its interest in Automation Software,
Incorporated to its joint venture partner, Brown & Sharpe Manufacturing Co.
(NYSE:BNS) of Kingston, Rhode Island for $3.0 million. Net cash proceeds from
the sale were $1.8 million, and as a result of the company's investment of
approximately $1.4 million in the joint venture as of the date of the sale, a
net after-tax gain of $405 thousand was recognized in the quarter ended

    On March 8, 1999, the Company and Anteon Corporation (Anteon) entered into a
definitive merger agreement under which Anteon will acquire all the outstanding
shares of the Company for $26.00 a share and the Company will become a wholly
owned subsidiary of Anteon. Anteon, based in Fairfax, Virginia, is a privately
held corporation that provides information technology, systems engineering and
technology solutions to customers throughout the United States and
internationally. The transaction is conditioned on the approval of the holders
of two-thirds of the Company's common stock as well as on customary regulatory
approvals and other closing conditions. The merger is expected to close by June
30, 1999.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    The following is a summary of significant accounting policies of the
Company:

    - PRINCIPLES OF CONSOLIDATION--The consolidated financial statements include
      the accounts of A&T and its subsidiaries. All significant intercompany
      accounts and transactions have been eliminated in consolidation.

    - CASH EQUIVALENTS--For financial statement purposes, the Company considers
      all investments with original maturities of three months or less at the
      time of purchase to be cash equivalents.

    - FAIR VALUE OF FINANCIAL INSTRUMENTS--The carrying amounts of the Company's
      financial instruments including cash, accounts receivable, accounts
      payable, accrued expenses and dividends payable approximate fair value due
      to the short term nature of these instruments. The carrying value of notes
      and other receivables and long term debt approximate fair value based on
      the instruments' interest rate, terms, maturity date, and collateral, if
      any, in comparison to the Company's incremental borrowing rate for similar
      financial instruments.

    - DEPRECIATION AND AMORTIZATION--Property, buildings, and equipment are
      stated at cost. Depreciation of buildings and equipment is provided over
      the estimated useful lives of the respective assets using the
      straight-line method. Leasehold improvements are amortized over the
      shorter of the lease term or the life of the asset.

    - LONG-LIVED ASSETS--Long-lived assets and certain identifiable intangibles
      are reviewed for impairment, based upon undiscounted future cash flows,
      and appropriate losses are recognized whenever the carrying amount of an
      asset may not be recovered in accordance with Statement of Financial

      ASSETS AND FOR LONG-LIVED ASSETS TO BE DISPOSED OF.

    - GOODWILL--Goodwill relating to the Company's acquisitions represents the
      excess of cost over the fair value of net assets acquired and is amortized
      on a straight-line basis over periods ranging from two to thirty years.
      Determination of the straight-line period is dependent on the nature of
      the operations acquired. The Company evaluates the recoverability of
      goodwill on a periodic basis to assure that changes in facts and
      circumstances do not suggest that recoverability has been impaired. This
      analysis relies on a number of factors, including operating results,
      business plans, budgets, economic projections, and changes in management's
      strategic direction or market emphasis. The test of recoverability for
      goodwill is a comparison of the unamortized balance to expected cumulative
      (undiscounted) operating income of the acquired business or enterprise
      over the remaining portion of the amortization period. If the book value
      of goodwill exceeds undiscounted future operating income, the writedown is
      computed as the excess of the unamortized balance of the asset over the
      present value of operating income discounted at the Company's weighted
      average cost of capital over the remaining amortization period.

    - PRODUCT DEVELOPMENT COSTS--Product development costs represent
      expenditures for the development of software products that have been
      capitalized in accordance with Statement of Financial Accounting Standards
      No. 86, ACCOUNTING FOR THE COSTS OF COMPUTER SOFTWARE TO BE SOLD, LEASED,
      OR OTHERWISE MARKETED. Amortization is computed on an individual product
      basis and is the greater of (a) the ratio of current gross revenues for a
      product to the total of current and anticipated future gross revenues for
      that product or (b) the amount computed using the straight-line method
      over the remaining economic useful life of the product. The Company is
      currently using economic lives ranging from two to five years for all
      capitalized product development costs. Amortization of product development
      costs begins when the software product is available for general release to
      customers.

    - ACCOUNTING FOR STOCK-BASED COMPENSATION--The Company applies APB Opinion
      No. 25 and related Interpretations in accounting for its stock option
      plans. In October 1995, the Financial Accounting Standards Board issued
      Statement of Financial Accounting Standards No. 123, ACCOUNTING FOR
      STOCK-BASED COMPENSATION. Statement 123 addresses the accounting for the
      cost of stock-based compensation, such as stock options, and permits
      either expensing the cost of stock-based compensation over the vesting
      period or disclosing in the financial statement footnotes what this
      expense would have been. This cost would be measured at the grant date
      based upon estimated fair values, using option pricing models. The Company
      adopted the disclosure alternative of Statement 123.

    - REVENUE RECOGNITION--Revenue from contract services is earned under
      cost-reimbursement, time and material, and fixed-price contracts. Revenue
      under cost-reimbursement contracts is recognized as costs are incurred and
      under time and materials contracts as time is spent and as materials costs
      are incurred. Revenue under fixed price contracts is recognized on the
      percentage of completion basis. The majority of the Company's
      cost-reimbursement contracts are either cost-plus-fixed-fee or
      cost-plus-hourly-fee contracts. The contracts may either require the
      Company to work on defined tasks or deliver a specific number of hours of
      service. In either case, costs are reimbursed up to the contract-
      authorized cost ceiling as they are incurred. If a contracted task has not
      been completed or the specific number of hours of service has not been
      delivered at the time the authorized cost is expended, the Company may be
      required to complete the work or provide additional hours. The

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
     Company will be reimbursed for the additional costs but may not receive an
      additional fee or the fee may be prorated proportionately to the number of
      hours actually provided. Revenue under fixed price contracts, including
      applicable fees and estimated profits, is recorded on the percentage of
      completion basis. If estimates indicate a probable ultimate loss on a
      contract, provision is made immediately for the entire amount of the
      estimated future loss. Profit and losses accrued include the cumulative
      effect of changes in prior periods' cost estimates.

    - EARNINGS PER SHARE--The Company calculates earnings per share (EPS) in
      accordance with the provisions of Statement of Financial Accounting
      Standards No. 128, EARNINGS PER SHARE. Statement 128 requires the
      disclosure of basic EPS, which is computed by dividing income available to
      common shareholders by the weighted average number of common shares
      outstanding at the end of the period. Diluted EPS, which gives effect to
      all dilutive potential common shares outstanding, is also required.

    The following table reconciles net earnings to net earnings available to
common shareholders and basic weighted average number of shares to diluted
weighted average shares outstanding for the years ending March 31, 1999, 1998,
and 1997. Net earnings attributable to subsidiary stock options represents the
allocation of Integrated Performance Decisions (IPD), a former subsidiary of the
Company through August 1998, and Interactive Media Corp. (IMC) earnings to
holders of potentially dilutive options on IPD stock and IMC stock held by IPD
and IMC employees (see footnote 7).

</TABLE>

    Options to purchase 15,000, 1,000 and 500 shares of common stock at $21.06,
$21.88 and $22.00, respectively, per share were outstanding during fiscal 1999
but were not included in the computation of diluted EPS because the options'
exercise price was greater than the average market price of common shares.

    - DEFERRED COMPENSATION PLAN--The Company maintains a deferred compensation
      plan for certain officers, directors, and salaried employees. The plan is
      funded primarily through employee pre-tax contributions. The participants
      in the plan bear the risk of market value fluctuations of the underlying
      assets.

    During the year ended March 31, 1999, the Company adopted the provisions of
the Emerging Issues Task Force Issue 97-14, ACCOUNTING FOR DEFERRED COMPENSATION
ARRANGEMENTS WHERE AMOUNTS EARNED ARE HELD IN A RABBI TRUST AND INVESTED. EITF
97-14 requires deferred compensation plan sponsors to consolidate the accounts
of the deferred compensation plan with the accounts of the Company and to
account for the assets and liabilities of the deferred compensation plan in
accordance with other relevant accounting pronouncements. Accordingly, the
company has recorded all non-employer debt and equity

securities of the deferred compensation plan in the accompanying March 31, 1999
consolidated balance sheet at fair value, in accordance with Statement of
Financial Accounting Standards Statement No. 115, ACCOUNTING FOR CERTAIN
INVESTMENTS IN DEBT AND EQUITY SECURITIES. A&T common stock owned by the
deferred compensation plan has been recorded as treasury stock at its historical
cost, with the difference between historical cost and fair value as of the
implementation date of EITF 97-14 recorded as a transition differential within
additional paid-in capital, in accordance with EITF 97-14. The deferred
compensation liability is recorded at an amount equal to the fair value of all
assets held by the deferred compensation plan.

    Investment securities held by the deferred compensation plan at March 31,
1999 consist of A&T's common stock and other investments, and are classified as
trading securities. Trading securities are bought and held principally for the
purpose of selling them in the near term. Trading securities are recorded at
fair value in the consolidated financial statements, with all unrealized holding
gains and losses recorded currently in earnings.

    - USE OF ESTIMATES--The preparation of financial statements in conformity
      with generally accepted accounting principles requires management to make
      estimates and assumptions that affect the amounts reported in the
      financial statements and accompanying notes. Actual results could differ
      from reported results using those estimates.

expiration of the loan agreement. If converted, the term loan would be payable
in 20 substantially equal quarterly installments. The alternate rates of
interest for the term loan from which the Company can choose are the bank's base
rate, the bank's certificate of deposit rate plus 1%, or LIBOR plus 3/4%. There
is a commitment fee of 1/2% per annum on the average daily balance of the unused
portion of the first $5,000,000 of the commitment and 1/4% per annum on the
remaining unused portion of the commitment, payable quarterly. As of March 31,
1999 and 1998 the Company did not have any funds borrowed under its revolving
credit agreement.

    The revolving credit and term loan agreement places certain restrictions on
encumbering the Company's assets, incurring additional debt, and disposing of
any significant assets. It also requires that the Company maintain at least
$10,000,000 in working capital (excluding deferred income taxes), net worth of
at least $42,000,000, a debt-to-net-worth ratio of less than 2.5 to 1.0, an
interest coverage ratio of not less than two times interest paid or accrued, and
a debt service ratio of not less than 1.2 to 1.0. As of March 31, 1999, the
Company was in compliance with these covenants.

    Under current agreements, principal payments due on long-term debt during
each of the five fiscal years subsequent to March 31, 1999 are as follows:
$345,338 in 2000, $364,157 in 2001, $278,580 in 2002, $202,862 in 2003 and
$970,151 in 2004.

    The Company paid $488,987, $296,209, and $397,417 in interest on all debts
in fiscal 1999, 1998, and 1997, respectively.

    At March 31, 1999, the Company had federal and state net operating loss
carryforwards of approximately $206,000 and $1,370,000, respectively. Such
carryforwards have various expiration dates and begin to expire in the year
ended March 31, 2000. For financial purposes, a valuation allowance of $80,355
has been recognized to offset the deferred tax asset related to the portion of
the state net operating losses which the Company believes will more likely than
not expire unutilized.

    Management has evaluated the remaining temporary differences and concluded
that it is more likely than not that the Company will have sufficient taxable
income, of an appropriate character within the carryback and carryforward period
permitted by current tax law, to allow for the utilization of the deductible
amounts generating the deferred tax assets and, therefore, no valuation
allowance is required as of March 31, 1999 and 1998.

    The Company made federal and state income tax payments of $3,538,312,
$3,568,245, and $2,707,724, during fiscal 1999, 1998, and 1997, respectively.

(7) STOCK OPTIONS

    A&T has granted common stock options to certain key employees under its

    The fair value of each stock option grant has been estimated on the date of
grant using the Black-Scholes option pricing model with the following weighted-
average assumptions:

</TABLE>

    The weighted-average fair values of options at the date of grant were $7.87,
$5.29, and $3.19 during fiscal 1999, 1998, and 1997, respectively.

    In addition, the Company can grant stock options to certain key employees of
Interactive Media Corp., a subsidiary of the Company, to purchase up to 20.2% of
IMC's authorized common stock. The price of the options as of the date of award
and subsequent valuation is based on a calculation considering book value per
share and an earnings factor. Approximately 88% of the available options have
been granted to date; none have been exercised.

(8) EMPLOYEE BENEFIT PLANS

    The Company's Savings and Investment Plan is a discretionary contribution
plan as defined in the Internal Revenue Code, Section 401(a)(27). The plan
covers substantially all of the Company's full-time employees. The Company's
contributions are made at the discretion of the Board of Directors for any plan
year. For the plan years ended December 31, 1998, 1997, and 1996, the Company
matched up to 50% of a participant's contribution of up to a maximum of 6% of
the participant's compensation, depending on the business unit to which the
participant was assigned. The Company's matching contributions to this plan were
$2,907,818 $1,847,496, and $1,767,992 for the years ended March 31, 1999, 1998,
and 1997, respectively. One of the investment options available under the
Company's Savings and Investment Plan is the purchase of the Company's common
stock. The Plan owned 179,896, 151,191, and 126,626 shares of common stock of
the Company at March 31, 1999, 1998, and 1997, respectively.

    The A&T Employee Stock Ownership Plan (ESOP) covers substantially all
full-time employees. Contributions to the plan are made at the discretion of the
Board of Directors for any plan year. The Company's contributions to the plan
amounted to $109,900, $101,600, and $112,000 for fiscal 1999, 1998, and 1997,
respectively. The plan owned 521,594, 532,694, and 571,319 shares of common

    Lease expense amounted to approximately $5,534,000, $5,776,000, and
$5,138,000, in fiscal 1999, 1998, and 1997, respectively.

    The U.S. Government has the right to audit and make retroactive adjustments
under certain contracts. Audits through March 31, 1997 have been completed. In
the opinion of management, adjustments, if any, resulting from audits for the
years ended March 31, 1998 and 1999 will not have a material effect on the
Company's consolidated financial statements.

    In addition, government funding continues to be dependent on congressional
approval of program level funding and on contracting agency approval for the
Company's work. The extent to which backlog will be funded in the future cannot
be determined.

    Under the terms of the Design Systems & Services, Inc. purchase agreement
executed in fiscal 1995, the Company is committed to make contingent payments up
to $400,000 to the former owner of the company. Contingent payments are based on
15% of revenues derived from sales of a ship design software product made
between the purchase date and April 30, 1999. The Company made contingent
payments to the former owner totaling $48,155 and $66,682 during fiscal 1999 and
fiscal 1998, respectively.

    Under the terms of the UP purchase agreement, if the aggregate net profit of
Interactive Media for the eight fiscal quarters ending September 30, 1999 ("the
Second Determination Date") is greater than

two times the combined cumulative net profit of Interactive Media and UP for the
four quarters ending September 30, 1997, the Company is obligated to pay to the
former owners of UP 81,100 shares of Interactive Media stock, or cash of
$2,250,000, or a combination of stock and cash which together equal the
appraised value of the contingent stock payment at the Second Determination
Date. However, the former owners of UP may not elect to receive an aggregate
amount of cash in excess of $2,250,000. If at the Second Determination Date, the
net profit of Interactive Media for the eight fiscal quarters ending September
30, 1999 is equal to or greater than 75%, but less than or equal to 100%, of two
times the combined cumulative net profit of Interactive Media and UP for the
four quarters ending September 30, 1997, the Company will be obligated to pay
the former owners of UP 40,550 shares of Interactive Media stock, or cash of
$1,125,000, or a combination of stock and cash which together equal the
appraised value of the contingent stock payment at the determination date.
However, the former owners of UP may not elect to receive an aggregate amount of
cash in excess of $1,125,000. If the merger with Anteon Corporation is
completed, under the terms of the UP purchase agreement the contingent payment
due to the former owners of UP, Inc. on September 30, 1999 would be payable upon
closing.

    In fiscal 1997, the Company received $450,000 under the terms of a
development agreement with the Connecticut Department of Economic Development to
fund technology-based training development. Under the terms of the agreement,
the Company is required to pay royalties equal to 3% of gross sales of
technology-based training products initiated in Connecticut. Royalty payments
will be deemed to be paid in full when royalty payments are equal to a return on
investment of 15% and the Company has maintained a Connecticut presence. Under
the terms of the agreement, the Company made royalty payments totaling $63,000
in fiscal 1999 and $75,085 in fiscal 1998.

    In fiscal 1995 and 1996, the Company received $200,000 under the terms of a
development agreement executed in October 1994 with a state-financed
corporation, Connecticut Innovations, Inc. (CII), to assist in funding the
development of commercial imaging processing products and services. Effective
November 30, 1998, CII and the Company terminated the Development Agreement. As
of the date of termination, CII had advanced to the Company $200,000 in
development funds and the Company had reimbursed CII $42,035 under terms of that
Development Agreement. Under the termination agreement, the Company assigned all
rights related to the commercial imaging products developed under the agreement
to CII, and CII released the Company from any further obligation to reimburse
CII for any Development Funds advanced by CII to the Company.

    The Company may from time to time be involved in various claims and legal
actions arising in the ordinary course of business. In the opinion of
management, the ultimate disposition of these matters will not have a material
adverse effect on the Company's consolidated financial position or results of
operations.

(11) SEGMENT REPORTING

    The Company operates principally in two segments, Engineering and
Information Technologies (Engineering/IT), and technology-based training, which
it develops through its wholly owned subsidiary, Interactive Media Corp.
(Interactive Media). The Engineering/IT segment serves primarily the needs of
the Department of Defense while the Interactive Media segment targets both
government and commercial customers. The Company's management measures
performance based upon each segment's operating earnings. Total revenue by
segment includes both sales to unaffiliated customers, as reported in the
Company's consolidated statements of earnings, and intersegment sales.

No person has been authorized to give any information or to make any
representations other than those contained in this prospectus, and, if given or
made, such information or representations must not be relied upon as having been
authorized. This prospectus does not constitute an offer to sell or the
solicitation of an offer to buy any securities other than the securities to
which it relates or an offer to sell or the solicitation of an offer to buy such
securities in any circumstances in which such offer or solicitation is unlawful.
Neither the delivery of this prospectus nor any sale made hereunder shall, under
any circumstances, create any implication that there has been no change in the
affairs of Anteon Corporation since the date hereof or that the information
contained herein is correct as of any time subsequent to its date.

                                    PART II
                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    The laws of the Commonwealth of Virginia pursuant to which the Company is
incorporated permit it to indemnify its officers and directors against certain
liabilities with the approval of its shareholders. The articles of incorporation
of the Company, which have been approved by its shareholders, provide for the
indemnification of each director and officer (including former directors and
officers and each person who may have served at the request of the Company as a
director or officer of any other legal entity and, in all such cases, his or her
heirs, executors and administrators) against liabilities (including expenses)
reasonably incurred by him or her in connection with any actual or threatened
action, suit or proceeding to which he or she may be made party by reason of his
or her being or having been a director or officer of the Company, except in
relation to any action, suit or proceeding in which he or she has been adjudged
liable because of willful misconduct or a knowing violation of the criminal law.

    The Company has purchased officers' and directors' liability insurance
policies. Within the limits of their coverage, the policies insure (1) the
directors and officers of the Company against certain losses resulting from
claims against them in their capacities as directors and officers to the extent
that such losses are not indemnified by the Company and (2) the Company to the
extent that it indemnifies such directors and officers for losses as permitted
under the laws of Virginia.

ITEM 21. EXHIBITS AND FINANCIAL STATEMENT SCHEDULES.

    The Exhibit Index beginning on page E-1 is hereby incorporated by reference.

ITEM 22. UNDERTAKINGS.

    The undersigned registrant hereby undertakes:

    (a) That, for purposes of determining any liability under the Securities
Act, each filing of the registrant's annual report pursuant to Section 13(a) or
15(d) of the Exchange Act of 1934 that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial BONA FIDE offering thereof.

    (b) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the 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.

    (c) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11 or 13 of this form, within one business day of receipt of such
request, and to send the incorporated documents by first class mail or other
equally prompt means. This includes information contained in documents filed
subsequent to the effective date of the registration statement through the date
of responding to the request.

    (d) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.
