January o, 2006


Dear Stockholder:

         You are cordially invited to attend a special meeting of stockholders
of Anteon International Corporation to be held on o, 2006 at 10:00 a.m. local
time. The meeting will take place at o.

         At the special meeting, we will ask you to adopt the agreement and plan
of merger, dated December 13, 2005, by and among General Dynamics Corporation,
Avenger Acquisition Corporation, an indirect, wholly-owned subsidiary of General
Dynamics Corporation, and Anteon International Corporation (the "merger
agreement"), and approve the merger of Avenger Acquisition Corporation with and
into Anteon International Corporation (the "merger") provided for in the merger
agreement. If the merger is completed, each holder of shares of our common stock
will be entitled to receive $55.50 in cash in exchange for each share of our
common stock held, as more fully described in the enclosed proxy statement, and
Anteon International Corporation will become an indirect, wholly-owned
subsidiary of General Dynamics Corporation.

         At the specual meeting, we will also ask you to consider and vote upon
a proposal to grant discretionary authority to the proxies to vote for
adjournment of the special meeting for the purpose of soliciting additional
proxies if there are not sufficient votes at the special meeting to approve the
merger proposal.

         After careful consideration, our board of directors approved the merger
agreement and the merger and has declared the merger agreement and the merger
advisable and in the best interests of Anteon International Corporation and our
stockholders. OUR BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR THE ADOPTION
OF THE MERGER AGREEMENT AND THE APPROVAL OF THE MERGER AND FOR THE GRANTING OF
DISCRETIONARY AUTHORITY TO THE PROXIES TO VOTE FOR ADJOURNMENT OF THE SPECIAL
MEETING IN ORDER TO SOLICIT ADDITIONAL PROXIES IF THERE ARE NOT SUFFICIENT VOTES
AT THE SPECIAL MEETING TO APPROVE THE MERGER PROPOSAL.

         The merger agreement must be adopted and the merger approved by the
affirmative vote of holders of at least a majority of our outstanding shares of
common stock that are entitled to vote at the special meeting. If the merger
agreement is adopted and the merger is approved, the merger agreement provides
that the closing of the merger will occur no later than the second business day
after the other conditions to the closing of the merger are satisfied or waived.

         The accompanying notice of special meeting of stockholders provides
specific information concerning the special meeting. The enclosed proxy
statement provides you with a summary of the merger and the merger agreement and
additional information about the parties involved. We urge you to read carefully
the enclosed proxy statement and the merger agreement, a copy of which is
included in the proxy statement as EXHIBIT A and the opinion of Bear, Stearns &
Co. Inc., a copy of which is included in the proxy statement as EXHIBIT B.

         Your vote is very important. Whether you plan to attend the special
meeting or not, please complete the enclosed proxy card and return it as
promptly as possible. The enclosed proxy card contains instructions regarding
voting. If you attend the special meeting, you may continue to have your shares
voted as instructed in the proxy or you may withdraw your proxy at the special
meeting and vote your shares in person. If you fail to vote by proxy or in
person, or fail to instruct your broker on how to vote, it will have the same
effect as a vote against adoption of the merger agreement and approval of the
merger.

                                         Sincerely,


                                         Joseph M. Kampf

    o    General Dynamics is a Delaware corporation with its principal executive
         offices located at 2941 Fairview Park Drive, Suite 100, Falls Church,
         Virginia 22042-4513, and its telephone number is (703) 876-3000.

MARKET PRICE AND DIVIDEND DATA (PAGE o)

    o    Our common stock, par value $0.01 per share, which we refer to in this
         proxy statement as our "common stock," is listed on The New York Stock
         Exchange under the ticker symbol "ANT." On o, 2006, the last full
         trading day prior to the date of this proxy statement, our common stock
         closed at $o per share. The average daily closing price of our common
         stock over the 30-day trading period ended o, 2006 was $o per share.

THE SPECIAL MEETING (PAGE o)

    o    The purpose of the special meeting is for you to consider and vote upon
         a proposal to adopt the Agreement and Plan of Merger, dated December
         13, 2005, by and among Anteon, General Dynamics and Merger Sub and to
         approve the merger provided for in that agreement and to vote upon a
         proposal to grant discretionary authority to the proxies to vote for
         adjournment of the special meeting in order to solicit additional
         proxies if there are not sufficient votes at the special meeting to
         approve the merger proposal.




    o    The holders of record of our common stock as of the close of business
         on the record date, which was o, 2006, are entitled to receive notice
         of, and to vote at, the special meeting. On the record date, there were
         o shares of Anteon common stock outstanding.

    o    The holders of a majority of the shares of Anteon common stock that
         were outstanding on the record date, represented in person or by proxy,
         will constitute a quorum for purposes of the special meeting.

    o    Completion of the merger requires the adoption of the merger agreement
         and approval of the merger provided for in that agreement by the
         affirmative vote of the holders of a majority of the outstanding shares
         of Anteon common stock entitled to vote at the special meeting. Because
         the required vote is based on the number of shares of Anteon common
         stock outstanding rather than on the number of votes cast, failure to
         vote your shares (including as a result of broker non-votes) and
         abstentions will have the same effect as voting against the adoption of
         the merger agreement and the approval of the merger.

    o    If a quorum is present, the approval of the adjournment proposal
         requires the affirmative vote of the holders of a majority of the votes
         present at the special meeting and entitled to vote on the adjournment
         proposal, in person or by proxy. If a quorum is present, failure to
         vote your shares (including as a result of broker non-votes) will have
         no effect on the outcome of the adjournment proposal. Abstentions will
         have the effect of a vote against the adjournment proposal. If a quorum
         is not present, broker non-votes will also have the effect of a vote
         against the adjournment proposal.

    o    As of the record date, our executive officers and directors owned an
         aggregate of approximately o shares of our common stock, entitling them
         to exercise approximately o% of the voting power of Anteon common stock
         entitled to vote at the special meeting. We currently expect that the
         executive officers and directors of Anteon will vote in favor of the
         adoption of the merger agreement and the approval of the merger.

THE MERGER (PAGE o)

    o    If the merger is completed, Merger Sub will be merged with and into
         Anteon with the result that Anteon will become a wholly-owned indirect
         subsidiary of General Dynamics. We sometimes use the term "surviving
         company" in this proxy statement to describe Anteon as the surviving
         entity following the merger.

    o    The merger will become effective when we file a certificate of merger
         with the Secretary of State of the State of Delaware, or at such later
         time that we and General Dynamics specify in the certificate of merger.

INTERESTS OF DIRECTORS AND EXECUTIVE OFFICERS IN THE MERGER (PAGE o)

    o    Our directors and executive officers have financial interests in the
         merger that may be different from your interests as a stockholder.
         These interests include:

                -     unvested stock options and restricted shares of Anteon
                      common stock held by directors and executive officers will
                      become fully vested immediately prior to the effective
                      time of the merger and will be cancelled at the effective
                      time of the merger in exchange for payments under the
                      merger agreement;

                                       2


                -     certain of our executive officers and key members of
                      management are entitled to receive severance payments and
                      benefits if their employment is terminated or adversely
                      affected under certain circumstances following the merger;
                      and

                -     the merger agreement provides for indemnification and
                      insurance arrangements for our current and former
                      directors and officers that will continue for six years
                      following the effective time of the merger.

BEAR STEARNS OPINION (PAGE o)

    o    Bear Stearns delivered a written opinion to our board of directors
         that, as of December 13, 2005, and based upon and subject to the
         assumptions, qualifications and limitations set forth in the written
         opinion, the merger consideration of $55.50 per share of our common
         stock is fair, from a financial point of view, to Anteon stockholders.

MERGER CONSIDERATION (PAGE o)

    o    If the merger is completed, each share of our common stock that is
         issued and outstanding immediately prior to the effective time of the
         merger, which we refer to in this proxy time as the "effective time,"
         (other than shares of common stock owned by Anteon, General Dynamics or
         Merger Sub or any of their respective subsidiaries and other than
         dissenting shares), together with any associated rights under Anteon's
         rights agreement, will be cancelled and automatically converted into
         the right to receive an amount in cash equal to $55.50, less any
         required withholding taxes and without interest.

STOCK OPTIONS; RESTRICTED STOCK AWARDS (PAGE o)

    o    The merger agreement provides that each outstanding option to acquire
         shares of common stock of Anteon will become fully vested immediately
         prior to, and will be cancelled at, the effective time of the merger.
         Each option holder will have the right to receive, within five business
         days after the effective time of the merger, a cash payment (less any
         required withholding taxes and without interest) equal to the product
         of (1) the excess, if any, of $55.50 over the applicable exercise price
         per share of the option and (2) the number of shares of common stock of
         Anteon issuable upon exercise of the option (whether or not the option
         is vested or exercisable).

    o    The merger agreement provides that all other stock-based awards
         outstanding immediately prior to the effective time (including
         restricted stock) will become fully vested by virtue of the merger and
         each holder of an award will have the right to receive, within five
         business days after the effective time of the merger, a cash payment
         (less any required withholding taxes and without interest) equal to the
         product of (1) $55.50 and (2) the number of shares subject to the
         award.

    o    Under the merger agreement, each participant in the Anteon
         International Corporation Employee Stock Purchase Plan will receive for
         any option under the plan outstanding at the effective time of the
         merger, in lieu of any other consideration, within five business days
         of the effective time of the merger, a cash payment (less any required
         withholding taxes and without interest) equal to the sum of (1) $55.50
         multiplied by the number of whole shares of the common stock of Anteon
         that would have been issued upon exercise of such options had they been
         exercised at the effective time of the merger and the

                                       3


         participant had purchased the maximum number of shares using the full
         amount of his or her "contributions" (as defined under the plan) and
         (2) any such "contributions" that would not have been sufficient to
         purchase a whole share.

                -     the representations and warranties of Anteon set forth in
                      the merger agreement, regardless of any materiality or

                      correct in all respects as of the date the merger closes
                      (except for any representations or warranties made as of a
                      specified date, which must only be true as of such
                      specified date), with only those exceptions as would not
                      individually or in the aggregate reasonably be expected to
                      have a material adverse effect on Anteon;

                      of the merger (which percentage will be reduced by the
                      amount of the dissenting shares of certain specified
                      stockholders).

                     QUESTIONS AND ANSWERS ABOUT THE MERGER

Q:    WHAT AM I BEING ASKED TO VOTE ON?

A:    You are being asked to vote to adopt the merger agreement and approve the
merger and to consider the grant of discretionary authority to the proxies to
vote for adjournment of the special meeting in order to solicit additional
proxies if there are not sufficient votes at the time of the meeting to approve
the merger proposal.

Q:    WHAT WILL I BE ENTITLED TO RECEIVE PURSUANT TO THE MERGER?

withholding taxes and without interest, for each outstanding share of our common
stock that you own as of the effective time of the merger.

Q:    HOW DOES THE BOARD OF DIRECTORS RECOMMEND THAT I VOTE?

A:    After careful consideration, our board of directors has approved the
merger agreement and the merger. Our board of directors recommends that our
stockholders vote FOR the adoption of the merger agreement and the approval of
the merger and FOR the granting of discretionary authority to the proxies to
vote for adjournment of the special meeting in order to solicit additional
proxies if there are not sufficient votes at the time of the meeting to approve
the merger proposal. For a description of factors considered by our board of
directors, please see "Recommendation of The Board of Directors" on page o and
"Reasons for the Merger" on page o.

Q:    WHY HAS THE MERGER BEEN PROPOSED?

A:    Our board of directors believes that the merger agreement and the merger,
on the terms and conditions set forth in the merger agreement, are advisable and
in the best interests of Anteon and its stockholders. You should read "Reasons
for the Merger" on page o for a discussion of some of the factors that our board
of directors considered in deciding to recommend the approval and adoption of
the merger agreement and the merger.

Q:    WHEN DO YOU EXPECT TO COMPLETE THE MERGER?

A:    We are working toward completing the merger as promptly as practicable. If
our stockholders vote to approve and adopt the merger agreement and the merger,
and the other conditions to the merger are satisfied or waived, then we intend
to consummate the merger as soon as practicable following the special meeting.
The merger agreement provides that the closing of the merger will occur no later
than the second business day after the other conditions to the closing of the
merger are satisfied or waived. We currently anticipate closing the merger no
later than the second quarter of this year.

Q:    IF THE MERGER IS COMPLETED, WHEN CAN I EXPECT TO RECEIVE THE MERGER
CONSIDERATION FOR MY SHARES?

A:    Promptly after the completion of the merger, you will receive a letter of
transmittal describing how you may exchange your shares for the merger
consideration. At that time, if you hold physical share certificates, you must
send your share certificates with your completed letter

                                       6


of transmittal to the paying agent. If you do not hold any physical share
certificates, you must execute a properly completed letter of transmittal and
arrange to electronically transfer your shares. You should not send your share
certificates to us or anyone else until you receive these instructions. You will
receive payment of your portion of the merger consideration after the paying
agent receives from you a properly completed letter of transmittal together with
your share certificates, or, if you do not hold any physical share certificates,
promptly after the paying agent receives your properly completed letter of
transmittal and electronic transfer of your shares.

Q:    IF I AM A U.S. PERSON, WHAT ARE THE TAX CONSEQUENCES OF THE MERGER TO ME?

A:    Your receipt of the merger consideration for your shares will be taxable
for federal income tax purposes. In general, you will recognize capital gain or
loss equal to the difference between the amount of merger consideration you
receive for your shares and the adjusted tax basis of your shares. For further
information on the material tax consequences of the merger, see "Material United
States Federal Income Tax Consequences of the Merger" on page o. You should
consult your own tax advisor for a full understanding of the tax consequences of
the merger to you.

Q:    WHAT VOTE IS REQUIRED TO APPROVE THE MERGER PROPOSAL AND THE ADJOURNMENT
PROPOSAL?

A:    Adoption of the merger agreement and approval of the merger requires the
affirmative vote of at least a majority of the shares of our common stock that
are outstanding and entitled to vote at the special meeting. If a quorum is
present, the adoption of the adjournment proposal requires the affirmative vote
of at least a majority of the shares of our common stock that are present at the
special meeting and entitled to vote on the adjournment proposal. We urge you to
complete, execute and return the enclosed proxy card to assure the
representation of your shares at the special meeting.

Q:    WHAT RIGHTS DO I HAVE IF I OPPOSE THE MERGER?

A:    You can vote against the merger by indicating a vote against the proposal
on your proxy card and signing and mailing your proxy card, or by voting against
the merger proposal in person at the special meeting. Shares of Anteon common
stock that are issued and outstanding immediately prior to the effective time of
the merger and which are held by our stockholders who have not voted in favor of
the merger agreement and have demanded and perfected their rights to appraisal
of their shares of Anteon common stock in the time and manner provided in
Section 262 of the Delaware General Corporation Law (referred to in this proxy
statement as the "DGCL") and, as of the effective time, have neither effectively
withdrawn nor lost their rights to such appraisal under the DGCL (referred to in
this proxy statement as the "dissenting shares") will not be converted into the
right to receive the merger consideration, but will, by virtue of the merger, be
entitled to only such rights as are granted by Section 262 of the DGCL; provided
that if such holder has failed to perfect or has effectively withdrawn or lost
his, her or its right to appraisal and payment under the DGCL, that holder's
shares of Anteon common stock will be deemed to have been converted, at the
effective time, into the right to receive the merger consideration. The full
text of Section 262 of the DGCL is attached as EXHIBIT C to this proxy
statement.

Q:    WHO IS ENTITLED TO VOTE AT THE SPECIAL MEETING?

A:    Only stockholders of record at the close of business on the record date,
o, 2006, are entitled to receive notice of the special meeting and to vote
shares of common stock that they held on that date at the special meeting, or
any postponements or adjournments of the special meeting. Each stockholder has
one vote for each share of common stock owned on the record date. As of

                                       7


the record date, there were o shares of common stock outstanding and entitled to
vote at the special meeting.

Q:    WHAT IS THE LOCATION, DATE AND TIME OF THE SPECIAL MEETING?

A:    The special meeting will be held on o, 2006, at 10:00 a.m. local time, at
o.

Q:    WHAT HAPPENS IF I SELL MY SHARES BEFORE THE SPECIAL MEETING?

A:    The record date for the special meeting, o, 2006, is earlier than the date
of the special meeting. If you held your shares on the record date but transfer
them before the special meeting and without granting a proxy, you will retain
your right to vote at the special meeting, but not the right to receive the
merger consideration for the shares. The right to receive the merger
consideration will pass to the person who owns your shares when the merger is
completed.

Q:    HOW DO I VOTE?

A:    Mark, sign, date and return the enclosed proxy card in the postage-paid
envelope provided, or submit a proxy by telephone or via the Internet in
accordance with the instructions on the enclosed proxy card or the voting
instruction form received from any broker, dealer, trustee, bank or other
nominee that may hold your Anteon shares on your behalf, as soon as possible so
that your shares can be voted at the special meeting.

Q:    WHAT HAPPENS IF I DO NOT RETURN A PROXY CARD?

      If you fail to either return your proxy card or vote in person at the
special meeting, or if you mark your proxy card "abstain," the effect will be
the same as a vote against the merger proposal. If you sign and return your
proxy card and fail to indicate your vote on your proxy, your shares will be
counted as a vote in favor of adopting the merger agreement and approving the
merger.

Q:    IF MY SHARES ARE HELD FOR ME BY MY BROKER, WILL MY BROKER VOTE MY SHARES
FOR ME?

A:    If you hold your shares in "street name" through a broker or other
nominee, your broker or nominee will not vote your shares unless you provide
instructions on how to vote. You should instruct your broker or nominee how to
vote your shares by following the directions your broker or nominee will provide
to you. If you do not provide instructions to your broker or nominee, your
shares will not be voted and this will have the same effect as a vote against
the proposal to approve and adopt the merger agreement and the merger. If a
quorum is present, but you did not provide instructions to your broker or
nominee your shares will not be voted and this will have no effect on the
outcome of the adjournment proposal. If a quorum is not present, but you did not
provide instructions to your broker or nominee your shares will not be voted and
this will have the same effect as a vote against the adjournment proposal.

Q:    MAY I VOTE IN PERSON?

A:    Yes. You may vote in person at the special meeting, rather than signing
and returning your proxy card, if you own shares in your own name. Provided that
you bring a legal proxy from your broker, dealer, trustee, bank or other nominee
and present it at the special meeting, you may also vote in person at the
special meeting if your shares are held in "street name" through a

                                       8


broker, dealer, trustee, bank or other nominee. You may be asked to present
photo identification for admittance.

Q:    MAY I CHANGE MY VOTE AFTER I HAVE MAILED MY SIGNED PROXY CARD?

A:    Yes. You may change your vote at any time before the shares reflected on
your proxy card are voted at the special meeting. If you own your shares in your
name, you can do this in one of three ways. First, you can send a written notice
of revocation to our secretary at our principal executive offices. Second, you
can mark, sign, date and return a new proxy card. Third, you can attend the
meeting and vote in person. Your attendance alone will not revoke your proxy. If
you submitted a proxy by telephone or via the Internet, you may revoke your
proxy by submitting a new proxy by telephone or via the Internet. If you have
instructed a broker, dealer, trustee, bank or other nominee to vote your shares,
you must follow the directions received from the broker, dealer, trustee, bank
or other nominee to change your instructions.

Q:    WHAT WILL HAPPEN TO MY SHARES AFTER COMPLETION OF THE MERGER?

A:    Following completion of the merger, your shares will be cancelled and will
represent only the right to receive the merger consideration of $55.50 per share
in cash, without interest, unless you perfect and exercise your appraisal
rights. Trading in our common stock on The New York Stock Exchange will cease.
Price quotations for our common stock will no longer be available and we will
cease filing periodic reports with the Securities and Exchange Commission (which
we refer to in this proxy statement as the "SEC") under the Securities Exchange
Act of 1934, as amended.

Q:    HAVE ANY STOCKHOLDERS ALREADY AGREED TO APPROVE THE MERGER?

A:    No. There are no agreements between the Merger Sub or General Dynamics and
any Anteon stockholder in which that stockholder has agreed to vote in favor of
adopting the merger agreement and approving the merger.

Q:    WHAT HAPPENS TO ANTEON ONCE THE MERGER IS COMPLETED?

A:    Once the merger is completed, Anteon will be an indirect, wholly-owned
subsidiary of General Dynamics, and the current holders of Anteon common stock
will no longer have any ownership interest in Anteon's future earnings or
growth.

Q:    WHAT DO I NEED TO DO NOW?

A:    This proxy statement contains important information regarding the merger
agreement and the merger, as well as information about us, General Dynamics and
Merger Sub. It also contains important information about some of what our board
of directors considered in adopting the merger agreement and approving the
merger. We urge to you read this proxy statement carefully, including the
exhibits. You may also want to review the documents referenced in the section
captioned "Where You Can Find Additional Information" on page o.

Q:    SHOULD I SEND MY SHARE CERTIFICATES NOW?

A:    No. After the merger is completed, a paying agent will send you a letter
of transmittal describing how you may exchange your share certificates for the
merger consideration. At that

                                       9


time, you must send in your share certificates or execute an appropriate
instrument of transfer of your shares of common stock, as applicable, with your
completed letter of transmittal to the paying agent to receive the merger
consideration. If you do not hold any physical share certificates, you must
execute a properly completed letter of transmittal and arrange to electronically
transfer your shares of common stock.

Q:    WHERE CAN I FIND MORE INFORMATION ABOUT ANTEON?

A:    We file certain information with the SEC under the Securities Exchange Act
of 1934, as amended. You may read and copy this information at the SEC's public
reference facilities. You may call the SEC at 1-800-SEC-0330 for information
about these facilities. This information is also available at the Internet site
the SEC maintains at www.sec.gov and on our website at www.anteon.com.
Information contained on our website is not part of, or incorporated in, this
proxy statement. You can also request copies of these documents from us. See
"Where You Can Find Additional Information" on page o.

Q:    HOW WILL PROXY HOLDERS VOTE MY SHARES?

A:    If you complete and properly sign the proxy card attached to this proxy
statement and return it to us prior to the special meeting, your shares will be
voted as you direct. If you sign the proxy card but no direction is otherwise
made, your shares will be voted FOR the adoption of the merger agreement and the
approval of the merger and FOR the proposal to grant discretionary authority to
the proxies to vote for adjournment of the special meeting in order to solicit
additional proxies if there are not sufficient votes at the special meeting to
approve the merger proposal. Our board of directors recommends a vote FOR the
adoption of the merger agreement and the approval of the merger and FOR the
proposal to grant discretionary authority to the proxies to vote for adjournment
of the special meeting in order to solicit additional proxies if there are not
sufficient votes at the special meeting to approve the merger proposal. Our
board of directors' recommendation is set forth, together with the description
of the proposal, in this proxy statement. See "Recommendation of Our Board of
Directors" on page o.

Q:    WHO WILL SOLICIT AND PAY THE COST OF SOLICITING PROXIES?

cost of soliciting proxies. In addition to solicitation by mail and, without
additional compensation for these services, proxies may be solicited by
telephone and facsimile, by mail, on the Internet or in person. [We will pay

solicitation materials to the beneficial owners of shares of common stock held
of record by such person, and we will, upon request of such record holders,
reimburse forwarding charges and out-of-pocket expenses.

                               THE SPECIAL MEETING

THE PROPOSALS

         This proxy statement is being furnished to our stockholders in
connection with the solicitation of proxies by the Anteon board of directors for
use at a special meeting to be held at o on o, 2006, at 10:00 a.m. local time.
The purpose of the special meeting is for you to consider and vote upon a
proposal to adopt the Agreement and Plan of Merger, dated December 13, 2005, by
and among Anteon, General Dynamics and Merger Sub, which provides for the merger
of Merger Sub with and into Anteon with the result that Anteon will become an
indirect, wholly-owned subsidiary of General Dynamics, to consider and vote upon
a proposal to grant discretionary authority to adjourn the special meeting for
the purpose of soliciting additional proxies and to transact any other business
that may properly come before the special meeting or any adjournment or
postponement thereof. A copy of the merger agreement is attached as EXHIBIT A to
this proxy statement.

RECORD DATE AND VOTING

         The holders of record of our common stock as of the close of business
on the record date, which was o, 2006, are entitled to receive notice of, and to
vote at, the special meeting. On the record date, there were o shares of Anteon
common stock outstanding.

         The holders of a majority of the shares of Anteon common stock that
were outstanding on the record date, represented in person or by proxy, will
constitute a quorum for purposes of the special meeting. A quorum is necessary
to hold the special meeting. Any shares of Anteon common stock held in treasury
by Anteon or by any of its subsidiaries are not considered to be outstanding for
purposes of determining a quorum. In accordance with Delaware law, abstentions
and broker non-votes will be counted as shares present for the purposes of
determining the presence of a quorum. "Broker non-votes" result when the
beneficial owners of shares of common stock do not provide specific voting
instructions to their brokers. Under the rules of the New York Stock Exchange,
brokers are precluded from exercising their voting discretion with respect to
the approval of non-routine matters.

REQUIRED VOTE

         Each share of Anteon common stock that was outstanding on the record
date entitles the holder to one vote at the special meeting. Completion of the
merger requires the adoption of the merger agreement and approval of the merger
by the affirmative vote of the holders of a majority of the outstanding shares
of Anteon common stock entitled to vote at the special meeting. BECAUSE THE
REQUIRED VOTE IS BASED ON THE NUMBER OF SHARES OF ANTEON COMMON STOCK
OUTSTANDING RATHER THAN ON THE NUMBER OF VOTES CAST, FAILURE TO VOTE YOUR SHARES
(INCLUDING AS A RESULT OF BROKER NON-VOTES) AND ABSTENTIONS WILL HAVE THE SAME
EFFECT AS VOTING AGAINST THE MERGER PROPOSAL. Approval of the adjournment
proposal requires the affirmative vote of the holders of the majority of votes
present and entitled to vote at the special meeting, in person or by proxy,
whether or not a quorum is present. If a quorum is present, failure to vote your
shares (including as a result of broker non-votes) will have no effect on the
outcome of the adjournment proposal. Abstentions will have the effect of a vote
against the adjournment proposal. If a quorum is not present, broker non-votes
will also have the effect of a vote against the adjournment proposal.

                                       11


         Record holders may cause their shares of Anteon common stock to be
voted using one of the following methods:

    o    mark, sign, date and return the enclosed proxy card by mail; or

    o    submit a proxy by telephone or through the Internet by following the
         instructions included with your proxy card; or

    o    appearing and voting in person by ballot at the special meeting.

         Regardless of whether you plan to attend the special meeting, you
should complete and return a proxy for your shares as described above as
promptly as possible.

         If you hold your shares through a bank, brokerage firm or nominee
(I.E., in "street name"), you must provide voting instructions in accordance
with the instructions on the voting instruction card that your bank, brokerage
firm or nominee provides to you. You should instruct your bank, brokerage firm
or nominee as to how to vote your shares, following the directions contained in
such voting instruction card.

         As of the record date, our executive officers and directors owned an
aggregate of approximately o shares of our common stock, entitling them to
exercise approximately o% of the voting power of Anteon common stock entitled to
vote at the special meeting. In addition, o shares of our common stock are owned
by investment partnerships organized by Caxton-Iseman Capital, Inc. (and other
persons who are contractually obligated to vote in accordance with these
investment partnerships) entitling these investment partnerships to exercise
approximately o% of the voting power of Anteon common stock entitled to vote at
the special meeting. We currently expect that the executive officers and
directors of Anteon and these investment partnerships will vote in favor of the
merger proposal.

PROXIES; REVOCATION

         If you complete and return a proxy, your shares will be voted at the
special meeting as you indicate on your proxy card. If no instructions are
indicated on your signed proxy card, your shares of Anteon common stock will be
voted "FOR" the adoption of the merger agreement and approval of the merger and
"FOR" the proposal to grant discretionary authority to the proxies to vote for
adjournment of the special meeting in order to solicit additional proxies if
there are not sufficient votes at the special meeting to approve the merger
proposal.

         You may revoke your proxy at any time, but only before the proxy is
voted at the special meeting, in any of three ways:

         o    by delivering a written revocation dated after the date of the
              proxy that is being revoked to the Corporate Secretary of Anteon
              at 3211 Jermantown Road, Fairfax, Virginia 22030-2801;

         o    by delivering to the Corporate Secretary of Anteon a later-dated,
              duly executed proxy or by submitting a telephone or Internet proxy
              at a date after the date of the previously submitted proxy
              relating to the same shares; or

         o    by attending the special meeting and voting in person by ballot.

                                       12


         Attendance at the special meeting will not, in itself, constitute
revocation of a previously granted proxy. If you hold your shares of Anteon
common stock in street name, you may revoke or change a previously given proxy
by following the instructions provided by the bank, brokerage firm, nominee or
other party that is the registered owner of the shares.

         Anteon will pay the costs of soliciting proxies for the special
meeting. Our officers, directors and employees may solicit proxies by telephone
and facsimile, by mail, on the Internet or in person. They will not be paid any
additional amounts for soliciting proxies. We will also request that individuals
and entities holding shares in their names, or in the names of their nominees,
that are beneficially owned by others, send proxy materials to and obtain
proxies from those beneficial owners, and will reimburse those holders for their
reasonable expenses in performing those services. We have retained o to assist
us in the solicitation of proxies, and will pay fees of approximately $o, plus
reimbursement of out-of-pocket expenses. In addition, our arrangement with o
includes provisions obligating us to indemnify o for certain liabilities that
could arise in connection with their solicitation of proxies on our behalf.

ADJOURNMENTS AND POSTPONEMENTS

         Whether or not a quorum is established at the special meeting, our
bylaws permit the presiding officer at the meeting or the stockholders present
in person or by proxy to adjourn the meeting from time to time by the vote of
the majority of the shares represented at that meeting without notice. The DGCL
requires that if a meeting is adjourned for more than 30 days after the date for
which the meeting was originally noticed, or if a new record date is fixed for
the adjourned meeting, written notice of the place, date and time of the
adjourned meeting must be given to the stockholders.

         If at the special meeting, the number of shares of Anteon common stock
represented in person or by proxy and voting in favor of adoption of the merger
agreement and approval of the merger is insufficient to adopt that proposal
under the DGCL and Anteon's board of directors determines that it is in the best
interests of Anteon stockholders, the proxy holders will move to adjourn the
special meeting in order to enable our board of directors to solicit additional
proxies in respect of such proposal. In that event, we will ask our stockholders
to vote only upon the adjournment proposal, and not the proposal regarding the
adoption of the merger agreement and approval of the merger. If the number of
shares of Anteon common stock represented in person or by proxy and voting in
favor of the adoption of the merger agreement and approval of the merger is
sufficient to adopt that proposal under the DGCL, the authority to vote upon the
adjournment proposal will not be used.

         Among other things, approval of the adjournment proposal could mean
that, even if we had received proxies representing a sufficient number of votes
against the adoption of the merger agreement and approval of the merger to
defeat that proposal, Anteon's board of directors would have the discretion to
adjourn the special meeting without a vote on the merger agreement and seek to
persuade the holders of those shares to change their votes to votes in favor of
adoption of the merger agreement and approval of the merger.

         Any adjournment or postponement of the special meeting for the purpose
of soliciting additional proxies will allow our stockholders who have already
sent in their proxies to revoke them at any time prior to their use at the
special meeting as adjourned or postponed, provided that, such revocation is in
compliance with the instructions (including as to timing) set forth in the
section entitled "--Proxies; Revocation."

                                   THE MERGER

BACKGROUND OF THE MERGER

         In pursuing alternatives for enhancing stockholder value, Anteon has
regularly considered various strategic opportunities, including deployment of
internal resources, business combinations, joint ventures, strategic alliances
and other strategic relationships. On several occasions, Anteon has received
unsolicited inquiries from other companies about the possibility of exploring
business combination transactions, including an inquiry from General Dynamics
during 2003. Anteon's management held preliminary exploratory discussions with
certain of these companies and on two occasions entered into non-disclosure and
standstill agreements. None of these inquiries led to any proposals for a
business combination transaction.

         As part of this ongoing review, on August 11, 2005, Anteon's board of
directors met to discuss its goal of becoming a "tier 1" technology services
provider to the Federal government and whether an acquisition or business
combination transaction might be part of Anteon's growth strategy. At that
meeting, Anteon's board of directors encouraged management to continue exploring
possible strategic opportunities.

         In early October, 2005, Joseph M. Kampf, Anteon's CEO, was contacted by
General Dynamics and another major aerospace and defense contractor, which we
refer to as the Other Party, each inquiring as to whether Anteon would be
interested in discussing the strategic merits of a potential business
combination transaction. On October 11, Mr. Kampf met with Nicholas Chabraja,
General Dynamics' Chairman and CEO, to explore preliminarily a possible business
combination between Anteon and General Dynamics.

         On October 21, Anteon's management updated Anteon's board of directors
at its regularly scheduled board meeting about the interest expressed by General
Dynamics and the Other Party in a potential business combination with Anteon.
The board encouraged management to pursue these discussions.

         On October 25, Mr. Kampf met with a senior executive of the Other Party
to explore the possible business combination between Anteon and the Other Party.

         On November 2 and November 4, Anteon entered into non-disclosure and
standstill agreements with General Dynamics and the Other Party, respectively,
in order to facilitate discussions of a potential transaction between Anteon and
each of the other parties. On November 7, certain members of Anteon's senior
executive management team met with members of the General Dynamics management
team, at which time Anteon's senior management gave a

                                       16


presentation about Anteon's business. On November 8, Anteon's senior management
team gave a similar presentation to the Other Party's senior management.

         On November 15, at Mr. Chabraja's request, Mr. Kampf and Mr. Chabraja
met again to discuss the potential business combination. During this meeting,
Mr. Chabraja presented to Mr. Kampf two financial models for the possible
acquisition of Anteon by General Dynamics. Based on certain assumptions, the
first of the two models indicated that General Dynamics could pay up to $53.45
per outstanding Anteon share, and the second of the models, which included
certain additional assumptions, indicated that General Dynamics could pay up to
$54.36 per share.

         Mr. Kampf updated Anteon's board of directors on the status of the
discussions with each of the interested parties during a telephonic meeting on
November 16. At the beginning of the meeting, Paul Kaminski, a member of
Anteon's board of directors, recused himself from further discussions of
potential business combinations with the two interested parties in light of his
membership on General Dynamics' board of directors. Anteon's board of directors
received a preliminary presentation with respect to the fiduciary duties of
directors from Anteon's outside legal advisors. At the same meeting, Anteon's
board of directors authorized management to engage Bear, Stearns & Co., Inc. to
represent Anteon in discussions with the two interested parties and, in view of
the possibility that discussions might move quickly, voted to appoint a
committee, comprised of Frederick Iseman, Michael Smith and Mr. Kampf, to
coordinate the efforts of Anteon's legal and financial advisors and to negotiate
on behalf of the entire board of directors a potential transaction with the two
interested parties. Following the November 16 meeting, members of the committee
appointed by Anteon's board of directors and Anteon's counsel negotiated the
terms of Bear Stearns engagement, subject to approval by Anteon's board of
directors.

         Anteon's board of directors met again on November 18 to review the
status of discussions with the interested parties, to consider whether to
proceed further with these discussions at that time and to discuss a process for
moving forward with the two interested parties. Representatives of Paul, Weiss,
Rifkind, Wharton & Garrison LLP, Anteon's outside legal advisors, were present
at this meeting. The Board of Directors approved the engagement of Bear Stearns
and representatives of Bear Stearns joined the meeting. Anteon's board of
directors received a further presentation respecting certain of the fiduciary
duties of directors from Anteon's outside legal advisors and received a
presentation from representatives of Bear Stearns respecting Anteon's strategic
alternatives, industry background, and a preliminary review of various factors
that would affect the valuation of Anteon by General Dynamics, the Other Party
and other companies that might be interested in pursuing an acquisition of
Anteon.

         Anteon's board of directors considered various processes by which an
acquisition might be pursued, including a limited auction, a broad public
auction or a process focusing on the two parties who had recently expressed an
interest in Anteon. While the board acknowledged the potential advantages of an
auction process, it determined that on balance Anteon should pursue an expedited
process with the two parties that had recently expressed an interest in
acquiring Anteon. Among the factors that Anteon considered in reaching this
determination was the view of Bear Stearns that the two interested parties were
the most probable purchasers among the universe of likely potential purchasers.
Anteon's board of directors was also concerned that an auction process
materially increased the possibility of information leaks and disruption of
Anteon's business and relationships with its key employees and customers,
matters that Anteon's management believed could adversely affect Anteon and its
stockholders if an acquisition did not take place. Anteon's board of directors
also considered the views of its outside legal advisors and

                                       17


Bear Stearns that an agreement could likely be structured that would permit
other interested parties to make, and Anteon to accept, higher offers after
entering into a definitive acquisition agreement with either General Dynamics or
the Other Party.

         Between November 21 and November 30, Bear Stearns had periodic
discussions with General Dynamics and the Other Party. During these discussions,
the Other Party indicated that it had some concerns about its ability to
participate in the process within the expedited time frame proposed by Anteon.
Bear Stearns urged the Other Party to participate in the process.

         General Dynamics commenced due diligence related to Anteon's business
on December 2. On December 5, 2005, the Other Party informed Bear Stearns that
it would be unable to proceed with a strategic transaction with Anteon within
the contemplated timeframe for matters unrelated to Anteon. The Other Party
indicated to Bear Stearns that it remained very interested in a potential
transaction with Anteon and that it hoped to accelerate the resolution of
matters unrelated to Anteon so that it could participate in the process.

         On December 7, Mr. Chabraja contacted Bear Stearns and Bear Stearns
advised Mr. Kampf that General Dynamics' board of directors had authorized the
negotiation, execution and performance of an agreement pursuant to which General
Dynamics would acquire Anteon. On December 8, General Dynamics' legal advisor,
Jenner & Block LLP, provided Anteon's legal advisor, Paul Weiss, with a draft
merger agreement. During the weekend from December 8 until December 11, outside
legal advisors to Anteon and General Dynamics held a series of telephonic
conference calls to negotiate the draft merger agreement. Anteon's outside legal
advisors discussed the status of negotiations with the committee on several
occasions during this period. During the course of negotiations, General
Dynamics agreed to eliminate its initial requirement that certain of our
stockholders enter into voting agreements, the amount of the termination fee
payable by Anteon under certain circumstances was reduced from $50 million to
$40 million, General Dynamics agreed to eliminate or modify in a manner
favorable to Anteon certain conditions to the merger and General Dynamics agreed
to pay a termination fee of $40 million if the merger agreement were terminated
due to a failure to obtain antitrust regulatory clearance.

         On December 12, Bear Stearns had discussions with General Dynamics
respecting price. After discussing the range of values previously indicated to
Mr. Kampf, Mr. Chabraja stated that General Dynamics would proceed at $54.36,
the high end of the range. Anteon's board committee met to discuss the price per
share offered by General Dynamics. The committee determined that it would not
endorse $54.36 per share and instructed Bear Stearns to contact General
Dynamics. Representatives of Bear Stearns contacted Mr. Chabraja to discuss the
price per share and Anteon's unwillingness to approve a transaction at that
price. After internal discussions with his management team, Mr. Chabraja
indicated to Bear Stearns that General Dynamics was prepared to pay $55.00 per
share. Bear Stearns relayed this proposal to Anteon's board committee, which met
and decided to instruct Bear Stearns to inform General Dynamics that it would
not present that offer to the entire Anteon board of directors and to seek a
price of $56.00 per share. Later that evening, representatives of General
Dynamics responded that General Dynamics would be willing to offer $55.50 per
share if the termination fee were raised from $40 million to $42.5 million.
After consulting with Anteon's board committee, Bear Stearns indicated to
General Dynamics that the committee would take that proposal to the full Anteon
board of directors but that the board would have to consider that price in
conjunction with the totality of the terms of the merger agreement being
negotiated.

                                       18


         During the morning of December 13, representatives of Anteon and
General Dynamics and their outside legal advisors met by telephonic conference
calls to negotiate and finalize the merger agreement.

         During the afternoon of December 13, Anteon's board of directors met by
telephonic conference call to review the final terms and conditions of the
merger and the merger agreement with Anteon management and Anteon's outside
legal and financial advisors. A representative of Paul Weiss reviewed the
directors' fiduciary obligations in considering a transaction of this type and
the terms of the merger agreement. Representatives of Bear Stearns reviewed in
detail its financial analyses of the possible merger and rendered its oral
opinion, subsequently confirmed in writing that, as of such date, the
consideration proposed to be paid to Anteon's stockholders in the merger was
fair, from a financial point of view, to those stockholders. After Anteon's
board of directors concluded its deliberations, the Anteon board of directors,
among other things, approved the merger agreement, declared the merger agreement
and the merger advisable and in the best interest of Anteon and its stockholders
and resolved to recommend that our stockholders vote to adopt the merger
agreement and approve the merger. The vote was unanimous except that Dr.
Kaminski did not participate in the deliberations respecting the merger or
participate in the vote on the merger and the merger agreement.

         The merger agreement was signed by the parties late in the evening on
December 13, and on December 14 before the commencement of trading on the NYSE,
Anteon and General Dynamics each issued a press release announcing the execution
of the merger agreement.

ANTEON'S REASONS FOR THE MERGER; RECOMMENDATION OF THE BOARD OF DIRECTORS

         In reaching its decision to approve the merger agreement and the merger
and recommend the merger to our stockholders, Anteon's board of directors
consulted with Anteon's management, as well as its outside legal and financial
advisors, and considered a number of factors, including the following material
factors which Anteon's board of directors viewed as supporting its decision to
approve the merger agreement and the merger and recommend the merger to our
stockholders:

    o    KNOWLEDGE OF ANTEON'S BUSINESS. Based on its knowledge of Anteon's
         business, operations, prospects, financial condition and the historical
         market prices of Anteon common stock, Anteon's board of directors
         believed that it might take a significant period for Anteon's stock
         price to increase to the level represented by the merger consideration
         and that, in order to achieve such a potential increase, Anteon would
         likely need to continue to grow internally and possibly undertake other
         strategic initiatives, the success of which would be subject to a
         number of uncertainties, including implementation risk.

    o    KNOWLEDGE OF INDUSTRY. Anteon's board of directors considered its
         knowledge of current conditions and evolving trends in the federal
         technology services industry, including increased competition from
         larger companies that are able to compete aggressively in the sector,
         the risks associated with possible changes in defense spending levels
         and the likely effects of these factors on Anteon's potential growth,
         development and strategic options. Based on this knowledge, Anteon's
         board of directors believed that Anteon's ability to realize
         stockholder value without being part of a larger organization that
         would facilitate its ability to compete for large bundled services and
         system integration opportunities in the federal technology services
         industry was subject to increasing uncertainties.

                                       19


    o    KNOWLEDGE OF GENERAL DYNAMICS. Based on its knowledge of General
         Dynamics' business, operations, management, reputation and financial
         condition, Anteon's board of directors believed that there is a high
         probability that the transaction would be successfully completed on the
         agreed-upon terms once a merger agreement was entered into with General
         Dynamics.

    o    MERGER CONSIDERATION PREMIUM. The financial terms of the merger,
         including the fact that the $55.50 merger consideration represented an
         approximate 34.6% premium over the closing price of shares of Anteon
         common stock on the New York Stock Exchange on December 12, 2005, the
         last full trading day before the board met on December 13 to review and
         consider approval of the merger. Anteon's board of directors believed
         that this premium was substantial and, as noted above, in order for
         Anteon to be reasonably likely to achieve comparable trading levels the
         stockholders would be subject to a number of risks and uncertainties.

    o    CASH CONSIDERATION. The fact that the merger consideration consists
         solely of cash, and the merger agreement is not subject to any
         financing conditions. Anteon's board of directors believed that
         entering into the merger agreement created a reasonably high
         probability that our stockholders would be fairly compensated for the
         potential value in Anteon's business while eliminating the execution
         risks associated with achieving continued internal growth and
         implementing strategic initiatives. Additionally, Anteon's board of
         directors determined that entering into the merger agreement eliminates
         other uncertainties regarding Anteon successfully operating its
         business going forward as well as risks to the value of the merger
         consideration based on fluctuations in the trading value of General
         Dynamics' stock or other alternatives to cash.

    o    FAIRNESS OPINION. The financial presentation of Bear Stearns, including
         its opinion dated as of December 13, 2005, to the Anteon board of
         directors as to the fairness, from a financial point of view and as of
         the date of the opinion, of the merger consideration to be received by
         holders of Anteon common stock. See "--Fairness Opinion of Bear
         Stearns, & Co., Inc."

    o    ABILITY TO ACCEPT A SUPERIOR PROPOSAL. The provisions of the merger
         agreement permit Anteon's board of directors to consider, and under
         certain conditions, to accept an unsolicited superior proposal to
         comply with Anteon's board of directors' fiduciary duties to Anteon's
         stockholders.

    o    REGULATORY. The regulatory and other approvals required in connection
         with the merger and the likelihood such approvals would be received
         without unacceptable conditions. Anteon's board of directors believed
         that the businesses of Anteon and General Dynamics were largely
         complementary and therefore, that the merger did not present a
         substantial risk of not being completed because of objections from
         antitrust authorities. The board of directors also considered that the
         merger agreement contained a provision for a fee to be paid by General
         Dynamics under certain circumstances that reduced the risks to Anteon's
         stockholders associated with the transaction failing on antitrust
         grounds.

    o    IMPACT ON CUSTOMERS AND EMPLOYEES. Senior management's view that the
         acquisition of Anteon by General Dynamics will result in better service
         and enhanced capability offerings to Anteon's customers and that there
         were likely to be significant ongoing employment opportunities for
         Anteon's employees. The board of directors believed that these factors
         would lessen the risks of noncompletion of the transaction.

                                       20


         In addition, Anteon's board of directors considered the following risks
associated with its decision to approve the merger agreement and recommend the
merger to our stockholders:

    o    TERMINATION FEE. The merger agreement's non-solicitation and
         stockholder approval covenants and provision for the payment of a
         termination fee of $42.5 million in certain events, which the Anteon
         board of directors understood, while potentially having the effect of
         discouraging third parties from proposing a competing business
         transaction after the merger agreement was signed, were conditions to
         General Dynamics' willingness to enter into the merger agreement. In
         this regard, the Anteon board of directors, after receiving the advice
         of its outside legal counsel and Bear Stearns, concluded that such
         arrangements were customary for public company merger transactions and
         that these provisions, including the amount of the termination fee,
         were consistent with law and the proper exercise of the board's
         fiduciary duties.

    o    DISRUPTIONS. The potential risk of diverting management's focus and
         resources from other strategic opportunities and from operational
         matters while it is working to implement the merger. Anteon's board of
         directors believed that these risks were reasonable and worthwhile to
         undertake in light of the terms of the merger agreement, including the
         limited conditions to closing and termination rights, and the absence
         of a financing contingency and its understanding of the ability of
         General Dynamics to finance the transaction.

    o    CASH CONSIDERATION. The fact that the all-cash price, while providing
         relative certainty of value, would not allow our stockholders to
         participate in potential further appreciation of General Dynamics'
         stock or benefit from any future appreciation in the value of Anteon
         after the merger and would be taxable to our stockholders upon
         completion of the merger.

    o    OPERATING RESTRICTIONS. The merger agreement restricts Anteon's ability
         to engage in certain activities between the date the merger agreement
         was signed and the effective time of the merger, and these restrictions
         could prevent Anteon from taking advantage of business opportunities
         such as potential acquisitions. Anteon's board of directors believed
         these restrictions would not interfere with Anteon's ability to operate
         in the ordinary course of business, and any risks associated with these
         restrictions were outweighed by the high probability that the merger
         would be completed.

    o    INTERESTS OF DIRECTORS AND OFFICERS. The fact that some Anteon
         executive officers and directors have other interests in the merger
         that are in addition to their interests as Anteon stockholders and
         stock option holders, including executive severance arrangements with
         Anteon, the terms of which would entitle certain executives to
         specified compensation and benefits if prescribed events occur
         following the merger. See "Interests of Directors and Executive
         Officers in the Merger"; in this regard, Anteon's board of directors
         concluded that the merger should be approved despite the existence of
         these interests, given both its favorable view of the merger's
         financial terms as well its belief that the executive arrangements
         giving rise to these interests were reasonable.

         The foregoing discussion of the factors considered by Anteon's board of
directors is not intended to be exhaustive, but, rather, includes the material
factors considered by Anteon's board of directors. In reaching its decision to
approve the merger agreement and the merger, Anteon's board of directors did not
quantify or assign any relative weights to the factors considered, and
individual directors may have given different weights to different factors.
Anteon's board of directors considered all these factors as a whole, including
discussions with, and questioning of,

                                       21


Anteon's management and advisors, and overall, considered these factors to be
favorable to, and to support, its determination.

         ANTEON'S BOARD OF DIRECTORS DETERMINED THAT THE MERGER AND THE MERGER
AGREEMENT ARE ADVISABLE, AND FAIR TO AND IN THE BEST INTERESTS OF ANTEON AND OUR
STOCKHOLDERS, AND APPROVED THE MERGER AGREEMENT AND THE MERGER. DR. PAUL
KAMINSKI, ONE OF ANTEON'S DIRECTORS, DID NOT TAKE PART IN THE DELIBERATIONS
RESPECTING OR THE APPROVAL OF THE MERGER OR THE MERGER AGREEMENT. ANTEON'S BOARD
OF DIRECTORS RECOMMENDS THAT OUR STOCKHOLDERS VOTE "FOR" THE ADOPTION OF THE
MERGER AGREEMENT AND APPROVAL OF THE MERGER.

FAIRNESS OPINION OF BEAR STEARNS, & CO. INC.

         Pursuant to an engagement letter dated November 18, 2005, Anteon
retained Bear Stearns to act as its financial advisor with respect to a possible
sale of the company. In selecting Bear Stearns, Anteon's board of directors
considered the fact that Bear Stearns is an internationally recognized
investment banking firm with substantial experience advising companies in the
aerospace/defense industry and the government information technology ("IT")
services industry as well as substantial experience providing strategic advisory
services. Bear Stearns, as part of its investment banking business, is
continuously engaged in the evaluation of businesses and their debt and equity
securities in connection with mergers and acquisitions; underwritings, private
placements and other securities offerings; senior credit financings; valuations;
and general corporate advisory services.

         At the December 13, 2005 meeting of Anteon's board of directors, Bear
Stearns delivered its oral opinion, which was subsequently confirmed in writing,
that, as of December 13, 2005, and based upon and subject to the assumptions,
qualifications and limitations set forth in the written opinion, the per share
consideration to be received was fair, from a financial point of view, to the
stockholders of Anteon.

         The full text of Bear Stearns' written opinion is attached as Exhibit B
to this proxy statement and you should read the opinion carefully and in its
entirety. The opinion sets forth the assumptions made, some of the matters
considered and qualifications and limitations of the review undertaken by Bear
Stearns. The Bear Stearns opinion is subject to the assumptions and conditions
contained therein and is necessarily based on economic, market and other
conditions and the information made available to Bear Stearns as of the date of
the Bear Stearns opinion, and Bear Stearns assumes no responsibility for
updating or revising its opinion based on circumstances or events occurring
after the date of its opinion. In reading the discussion of the fairness opinion
set forth below, you should be aware that Bear Stearns' opinion:

    o    was provided to Anteon's board of directors solely for its benefit and
         use;

    o    did not constitute a recommendation to the board of directors of Anteon
         or any stockholder of Anteon as to how to vote in connection with the
         merger or otherwise; and

    o    did not address Anteon's underlying business decision to pursue the
         merger, the relative merits of the merger as compared to any
         alternative business strategies that might exist for Anteon or the
         effects of any other transaction in which Anteon might engage.

         Anteon did not provide specific instructions to, or place any
limitations on, Bear Stearns with respect to the procedures to be followed or
factors to be considered by it in performing its analyses or providing its
opinion.

                                       22


         In connection with rendering its opinion, Bear Stearns:

    o    reviewed the merger agreement;

    o    reviewed Anteon's Annual Reports to Stockholders and Annual Reports on
         Form 10-K for the years ended December 31, 2002, 2003 and 2004, its
         Quarterly Reports on Form 10-Q for the periods ended March 31, 2005,
         June 30, 2005 and September 30, 2005 and its Current Reports on Form
         8-K filed since December 31, 2004;

    o    reviewed General Dynamics' Annual Reports to Stockholders and Annual
         Reports on Form 10-K for the years ended December 31, 2002, 2003 and
         2004, its Quarterly Reports on Form 10-Q for the periods ended April 3,
         2005, July 3, 2005 and October 2, 2005 and its Current Reports on Form
         8-K filed since December 31, 2004;

    o    reviewed certain operating and financial information relating to
         Anteon's business and prospects, including forecasts for the five years
         ended December 31, 2009, which are referred to in this proxy statement
         as the Anteon forecasts, all as prepared and provided to Bear Stearns
         by Anteon's management;

    o    met with certain members of Anteon's senior management to discuss
         Anteon's business, operations, historical and projected financial
         results and future prospects;

    o    reviewed the historical prices, trading multiples and trading volume of
         the shares of Anteon common stock;

    o    reviewed publicly available financial data, stock market performance
         data and trading multiples of companies which Bear Stearns deemed
         generally comparable to Anteon;

    o    reviewed the terms of recent mergers and acquisitions involving
         companies which Bear Stearns deemed generally comparable to Anteon;

    o    performed discounted cash flow analyses based on the Anteon forecasts;

    o    reviewed the pro forma financial results, financial condition and
         capitalization of General Dynamics giving effect to the merger; and

    o    conducted such other studies, analyses, inquiries and investigations as
         Bear Stearns deemed appropriate.

         Bear Stearns relied upon and assumed, without independent verification,
the accuracy and completeness of the financial and other information provided to
or discussed with Bear Stearns by Anteon or obtained by Bear Stearns from public
sources, including, without limitation, the Anteon forecasts. With respect to
the Anteon forecasts, Bear Stearns relied on the representations of the senior
management of Anteon that the Anteon forecasts had been reasonably prepared on
bases reflecting the best available estimates and judgments of the senior
management of Anteon as to the expected future performance of Anteon. Bear
Stearns did not assume any responsibility for the independent verification of
any such information, including, without limitation, the Anteon forecasts, and
Bear Stearns further relied upon the assurances of the senior management of
Anteon that they were unaware of any facts that would make the information or
the Anteon forecasts incomplete or misleading.

                                       23


         In arriving at its opinion, Bear Stearns did not perform or obtain any
independent appraisal of the assets or liabilities (contingent or otherwise) of
Anteon, nor was Bear Stearns furnished with any such appraisals. Bear Stearns
assumed that the merger would be consummated in a timely manner and in
accordance with the terms of the merger agreement without any limitations,
restrictions, conditions, amendments or modifications, regulatory or otherwise,
that collectively would have a material effect on Anteon.

         Bear Stearns did not express any opinion as to the price or range of
prices at which the shares of Anteon common stock may trade subsequent to the
announcement of the merger.

         FINANCIAL ANALYSIS

         The following is a brief summary of the material financial analyses
performed by Bear Stearns and presented to Anteon's board of directors in
connection with rendering its fairness opinion. The following summary, however,
does not purport to be a complete description of the financial analyses
performed by Bear Stearns, and the order of analyses described does not
represent the relative importance or weight given to the analyses performed by
Bear Stearns.

         Some of the financial analyses summarized below include summary data
and information presented in tabular format. In order to understand fully the
financial analyses, the summary data and tables must be read together with the
full text of the analyses. Considering the summary data and tables alone could
create a misleading or incomplete view of Bear Stearns' financial analyses.

         COMPARABLE PUBLIC COMPANY TRADING ANALYSIS. Bear Stearns reviewed and
compared specific financial and operating metrics relating to Anteon with that
of selected publicly traded companies that Bear Stearns deemed comparable to
Anteon. Bear Stearns chose the companies used in the Comparable Public Company
Trading Analysis based on their similar business profiles and operating
characteristics. For Anteon, Bear Stearns included in its review the following
comparable public companies:

     o   CACI International, Inc.

     o   ManTech International Corporation

     o   MTC Technologies Inc.

     o   SRA International Inc.

         For each of the comparable public companies listed above, Bear Stearns
analyzed multiples of Enterprise Value (which is referred to as EV and is
calculated as the sum of the value of the common equity on a fully diluted basis
and the value of net debt, any minority interest and preferred stock) divided by
estimated (i) revenues, (ii) earnings before interest, income taxes,
depreciation and amortization (which is referred to as EBITDA), and (iii)
earnings before interest and taxes (which is referred to as EBIT), for the
calendar year ending December 31, 2006. Bear Stearns also analyzed multiples of
each company's stock price divided by estimated earnings per share (which is
referred to as EPS) for the calendar year ending December 31, 2006. This
analysis was compiled using publicly available information, including closing
stock market data as of December 8, 2005 and First Call consensus Wall Street
research estimates of revenue, EBITDA, EBIT and EPS for the calendar year ending
December 31, 2006. Bear Stearns calculated the following range of multiples for
the above comparable public companies:

                                       24


MULTIPLE                      HIGH          LOW           MEAN          MEDIAN
- --------                      ----          ---           ----          ------
EV/ 2006E Revenue             1.23x         0.84x         1.06x         1.08x
EV/ 2006E EBITDA              10.7x         8.9x          9.7x          9.7x
EV/ 2006E EBIT                12.7x         9.9x          11.2x         11.0x
Price/ 2006E EPS              20.6x         16.0x         18.2x         18.1x

         Bear Stearns calculated an implied per share equity value reference
range for Anteon of $36.67 to $44.51 based on the range of EV/ 2006E EBITDA
multiples of the comparable public companies.

         Bear Stearns compared the multiples of the comparable public companies
to the multiples implied for Anteon at the proposed transaction price of $55.50
per share. The following represents Anteon's implied multiples based on its CY
2006E revenue, EBITDA, EBIT, and EPS as provided in the Anteon forecasts:

     o   EV/ 2006E Revenue:  1.30x

     o   EV/ 2006E EBITDA: 13.2x

     o   EV/ 2006E EBIT: 13.8x

     o   Price 2006E EPS:  22.2x

         Bear Stearns observed that Anteon's implied enterprise value and equity
value multiples based on the proposed transaction price of $55.50 per share were
above the high end of the range of trading multiples for comparable public
companies.

         SELECTED COMPARABLE PRECEDENT TRANSACTIONS ANALYSIS: Bear Stearns
reviewed nine selected comparable precedent merger and acquisition transactions
(which are referred to as the comparable transactions) involving government IT
services companies as a means of comparison for the transaction. Bear Stearns
selected these precedent transactions based on the reasonably similar business
profiles and operating characteristics of the target companies in comparison
with Anteon. The precedent transactions selected include the following:

     o   DRS Technologies, Inc./Engineered Support Systems, Inc. (announced
         September 2005)

     o   L-3 Communications Corporation/The Titan Corporation (announced June
         2005)

     o   Nortel Networks Corporation/PEC Solutions Inc. (announced April 2005)

     o   Lockheed Martin Corporation/The Sytex Group, Inc. (announced February
         2005)

     o   BAE Systems plc/DigitalNet Holdings Inc. (announced (September 2004)

     o   CACI International, Inc./American Management Systems' US Defense and
         Intelligence Group (announced March 2004)

                                       25


     o   Lockheed Martin Corporation/Affiliated Computer Services' Federal
         Government IT business (announced August 2003)

     o   General Dynamics Corporation/Digital System Resources, Inc. (announced
         July 2003)

     o   General Dynamics Corporation/Veridian Corporation (announced June 2003)

         Bear Stearns analyzed the implied transaction EV multiples in these
comparable transactions as a multiple of the forward projected EBITDA for the
twelve-month period post-transaction as forecasted by Wall Street equity
research on or just prior to the date of the transaction, which is referred to
as Forward EBITDA. These comparable transaction multiples were compared with the
same multiple implied in the proposed merger based on the projections provided
by Anteon's management and assuming a $55.50 per share purchase price for Anteon
common stock.

         The comparable transactions reflected mean, median and high EV/Forward
EBITDA multiples of 10.4x, 10.4x, and 12.1x, respectively. Bear Stearns
calculated an implied per share equity value reference range for Anteon of
$37.98 to $50.58 based on comparable transaction multiples ranging from 9.2x to
12.1x EV/Forward EBITDA. This implied per share equity value reference range
compares with the proposed transaction price of $55.50 per share for Anteon,
which represents an implied multiple of 13.2x EV 2006E EBITDA.

         DISCOUNTED CASH FLOW ANALYSIS: Bear Stearns performed a discounted cash
flow analysis of Anteon for the purpose of determining the estimated equity
value range of Anteon. In conducting this analysis, Bear Stearns used the
projected after-tax unlevered free cash flows for Anteon based on the Anteon
forecasts plus its terminal value, calculated as a multiple of 9.0x to 11.0x
terminal period forward projected EBITDA, and discounted these items to
determine the present value using a range of discount rates that corresponded to
Anteon's estimated weighted average cost of capital, which is referred to as
WACC, during that period. Bear Stearns used a range of WACCs of 11% to 13%,
which was based on an unlevered beta range of 0.75 to 0.95 (determined by
observing Anteon's and comparable public companies' historical and projected
betas). Based on this analysis, Bear Stearns calculated an implied per share
equity value reference range for Anteon of between $44.06 to $56.56. This
compares to the proposed transaction price of $55.50 per share.

         CONSENSUS WALL STREET RESEARCH PRICE TARGET ANALYSIS: In reviewing
current Wall Street research estimates for Anteon, Bear Stearns observed that 12
of 15 firms providing equity research coverage as of December 8, 2005 reported
52-week stock price targets for Anteon. These 52-week stock price estimates
ranged between $45.00 and $55.00 with a mean and median price target of $51.08
and $52.00, respectively.

         PREMIUMS PAID ANALYSIS: Bear Stearns compared the premium proposed to
be paid in the merger with premiums paid in domestic change of control mergers
and acquisitions transactions announced between January 1, 2002 through November
30, 2005 with transaction values between $1.0 billion and $3.0 billion. Bear
Stearns calculated the premium per share paid by the acquiror with the share
price of the target prevailing 1-day, 1-week, and 1-month prior to the
announcement of the transactions. Bear Stearns observed that mean premiums for
this transaction universe were 21.4%, 24.1%, and 25.9%, respectively.

         Bear Stearns also reviewed the premiums paid in each of the
transactions discussed previously in the Selected Comparable Precedent
Transactions Analysis in which the target

                                       26


company was a standalone public company. The average 1-day, 7-day, and 30-day
premiums for this transaction universe were 24.7%, 24.0% and 29.2%,
respectively.

         These observed premiums were compared with the premiums implied in the
proposed transaction as of December 8, 2005 of 34.1%, 28.1% and 25.0% for the
1-day, 1-week, and 1-month periods, respectively.

         The preparation of a fairness opinion is a complex process and involves
various judgments and determinations as to the most appropriate and relevant
assumptions and financial analyses and the application of those methods to the
particular circumstances involved. Such an opinion is therefore not readily
susceptible to partial analysis or summary description, and taking portions of
the analyses set out above, without considering the analysis as a whole, would
create an incomplete and misleading picture of the processes underlying the
analyses considered in rendering the Bear Stearns opinion. Bear Stearns based
its analysis on assumptions that it deemed reasonable, including assumptions
concerning general business and economic conditions and industry-specific
factors. Bear Stearns did not form an opinion as to whether any individual
analysis or factor, whether positive or negative, considered in isolation,
supported or failed to support the Bear Stearns opinion. In arriving at its
opinion, Bear Stearns considered the results of all its analyses and did not
attribute any particular weight to any one analysis or factor. Bear Stearns
arrived at its ultimate opinion based on the results of all analyses undertaken
by it and assessed as a whole and believes that the totality of the factors
considered and analyses performed by Bear Stearns in connection with its opinion
operated collectively to support its determination as to the fairness of the per
share consideration to be received by the stockholders of Anteon. The analyses
performed by Bear Stearns, particularly those based on estimates and
projections, are not necessarily indicative of actual values or actual future
results, which may be significantly more or less favorable than suggested by
such analyses.

         None of the public companies used in the comparable public company
analysis described above are identical to Anteon, and none of the comparable
precedent transactions used in the precedent transactions analysis described
above are identical to the merger. Accordingly, an analysis of publicly traded
comparable companies and comparable precedent transactions is not strictly
mathematical; rather it involves complex considerations and judgments concerning
the differences in financial and operating characteristics of the companies and
precedent transactions and other factors that could affect the value of Anteon
and the public trading values of the companies and precedent transactions to
which they were compared. The analyses do not purport to be appraisals or to
reflect the prices at which any securities may trade at the present time or at
any time in the future.

           The form and amount of consideration payable in the merger were
determined through negotiations between Anteon and General Dynamics and approved
by the board of directors of Anteon. The Bear Stearns opinion was one of the
many factors taken into consideration by Anteon's board of directors.
Consequently, Bear Stearns' analysis should not be viewed as determinative of
the decision of Anteon's board of directors with respect to the fairness of the
per share consideration to be received by the stockholders of Anteon.

           Pursuant to the terms of Bear Stearns' engagement letter, Anteon has
agreed to pay Bear Stearns a cash fee equal to 0.70% of the aggregate merger
consideration, payable upon completion of the merger. In addition, a fee of $2.0
million was payable to Bear Stearns upon the rendering of its fairness opinion,
which will be credited against the fee payable upon completion of the merger. In
addition, Anteon has agreed to reimburse Bear Stearns for reasonable
out-of-pocket expenses incurred by Bear Stearns in connection with its
engagement and the transactions

                                       27


contemplated by the merger agreement, including reasonable fees and
disbursements of its legal counsel. Anteon has agreed to indemnify Bear Stearns
against certain liabilities arising out of or in connection with Bear Stearns'
engagement.

         Bear Stearns has been previously engaged by Anteon to provide certain
investment banking and other services, including participation as an underwriter
in Anteon's initial public offering of common stock in March of 2002 and a
subsequent follow-on offering of common stock in August of 2003, for which Bear
Stearns received customary fees. In addition, Bear Stearns or its affiliates in
the past have been engaged by General Dynamics or its affiliates to provide
certain investment banking and other services, including strategic advisory
services with respect to certain acquisitions and participation as an
underwriter in various debt financings, in matters unrelated to the merger, for
which it has received, or expects to receive, customary fees. Bear Stearns,
through one of its affiliates, is currently a participating lender in General
Dynamics' credit facilities, through which General Dynamics may obtain all or a
portion of the financing necessary to consummate the merger. Bear Stearns is
currently engaged, and in the past has been engaged, by Caxton-Iseman Capital,
Inc., an affiliate of Anteon, to provide certain investment banking and other
services in matters unrelated to the merger, for which it has received, or
expects to receive, customary compensation. In addition, various individuals and
entities affiliated with us may have passive minority investments in private
equity funds and partnerships managed by parties related to Caxton-Iseman
Capital, Inc.

             In the ordinary course of business, Bear Stearns and its affiliates
may actively trade the equity and debt securities and/or bank debt of Anteon
and/or General Dynamics for their own account and for the account of their
customers and, accordingly, may at any time hold a long or short position in the
securities or bank debt of Anteon and/or General Dynamics.

INTERESTS OF DIRECTORS, EXECUTIVE OFFICERS AND CERTAIN OTHER PERSONS IN THE
MERGER

         ANTEON STOCK OPTIONS

         As of the record date, there were o shares of our common stock subject
to stock options granted to our directors and executive officers under the
Amended and Restated Anteon International Corporation Omnibus Stock Plan, which
we refer to in this proxy statement as the "option plan."

         The merger agreement provides that each outstanding option to acquire
shares of common stock of Anteon granted under the Amended and Restated Anteon
International Corporation Omnibus Stock Plan will become fully vested
immediately prior to the effective time of the merger and will be cancelled at
the effective time of the merger. Each option holder will have the right to
receive, within five business days of the effective time of the merger, a cash
payment (less any required withholding taxes and without interest) equal to the
product of (1) the excess, if any, of $55.50 over the applicable exercise price
per share of the option and (2) the number of shares of common stock of Anteon
issuable upon exercise of the option (whether or not the option is vested or
exercisable).

         The following table summarizes the vested and unvested options held by
each of our directors and executive officers as of o, 2006, and the
consideration (calculated prior to any reduction for any required withholding
taxes) that each of them will receive pursuant to the merger agreement in
connection with the cancellation of his or her options:

         ANTEON RESTRICTED STOCK AWARDS

         Pursuant to the option plan, certain members of our board of directors
who are not also employees of Anteon were each granted 1,000 restricted shares
of Anteon common stock on August 11, 2005. As of the record date, none of these
restricted shares were vested. The merger agreement provides that each
restricted share of Anteon common stock will become fully vested by virtue of
the merger and each holder of a restricted share will have the right to receive,
within five business days of the effective time of the merger, a cash payment
(less any required withholding taxes and without interest) equal to the product
of (1) $55.50 and (2) the number of restricted shares held by that director.

         SEVERANCE AGREEMENTS

         Certain of our executive officers and certain key members of
management, (referred to in this proxy statement as the "executives") entered
into agreements with Anteon or its wholly-owned operating subsidiary, Anteon
Corporation, a Virginia corporation. The agreements provide for certain
compensation payments and other benefits to be paid to the executive by Anteon
for varying periods ranging up to 36 months if, after a change of control event
such as the merger, the executive's employment is involuntarily terminated
without cause, or if the executive resigns his/her employment for "Good Reason,"
as such term is defined in the agreement. The executive may not resign for "Good
Reason" unless he or she has first given notice to Anteon of the reason for that
resignation and Anteon has failed to reasonably cure the situation within thirty
days after receiving the executive's notice. In addition, the agreements provide
that for a one year period following such termination an executive will not
solicit our management employees or our customers. If an executive violates this
agreement not to solicit our management employees or our customers, Anteon has
the right to recover a portion of the compensation payments and other benefits
paid to that executive. If the payments under these severance agreements had
been triggered as of December 31, 2005, Messrs. Kampf, Ream, Johnson, Heilman
and Moskowitz would have been entitled to receive cash severance payments under
their respective severance agreements of $[______], $[________], $[_______],
$[_______], and

                                       29


$[________], respectively. In addition, the agreements provide each executive
with a tax gross-up payment to eliminate, after all taxes have been paid, any
costs that he would otherwise have as a result of any excise taxes to which he
may be subject by reason of his receipt of any payment, under his employment
agreement or otherwise, that constitutes an excess parachute payment under
Section 280G of the Code.

         INDEMNIFICATION OF DIRECTORS AND OFFICERS

         The merger agreement provides for indemnification and insurance
arrangements for our current and former directors and officers that will
continue for six years following the effective time of the merger. The merger
agreement provides that from and after the effective time of the merger, General
Dynamics will, and will cause Anteon as the surviving company in the merger to,
fulfill and honor in all respects, the obligations of Anteon pursuant to any
indemnification, exculpation or advancement of expenses provisions in favor of
the current or former directors, officers, employees or agents of Anteon or any
of its subsidiaries, or certain other parties, under the constitutional
documents of Anteon or its subsidiaries or any agreement between these
indemnified persons and Anteon or its subsidiaries in effect as of the date of
the merger agreement. The merger agreement also provides that for a period of
six years following the effective time of the merger the certificate of
incorporation and by-laws of Anteon as the surviving company will contain
provisions with respect to indemnification, exculpation and advancement of
expenses that are at least as favorable to the beneficiaries of these provisions
as those contained in Anteon's certificate of incorporation and by-laws in
effect on the date of the merger agreement.

         The merger agreement also provides that for a period of six years after
the effective time of the merger General Dynamics will cause to be maintained
directors and officers liability insurance and fiduciary liability insurance
arrangements substantially equivalent in scope and amount of coverage (and on
terms and conditions no less advantageous to the insureds) to the policies
maintained by Anteon as of the date of the merger agreement with respect to
claims arising from or relating to actions or omissions, or alleged actions or
omissions, occurring on or prior to the effective time of the merger. The merger
agreement provides that General Dynamics will not be required to make total
annual premium payments with respect to these insurance arrangements to the
extent the premiums exceed 200% of the last annual premium paid by Anteon prior
to the date of the merger agreement. If the annual premium costs necessary to
maintain this insurance coverage exceed 200% of the last annual premium paid by
Anteon, General Dynamics will maintain as much comparable directors and officers
liability insurance and fiduciary liability insurance as is reasonably
obtainable for an annual premium not exceeding 200% of the last annual premium
paid by Anteon.

         STOCKHOLDERS AGREEMENT INVOLVING AZIMUTH TECHNOLOGIES, L.P. AND
         AZIMUTH TECH II LLC

         Azimuth Technologies, L.P. and Azimuth Tech. II LLC are two of our
principal stockholders. The sole general partner of Azimuth Technologies, L.P.
and the sole managing member of Azimuth Tech. II LLC is Georgica (Azimuth
Technologies), L.P., the sole general partner of which is Georgica (Azimuth
Technologies), Inc., a corporation wholly-owned by Frederick J. Iseman, the
chairman of our Board of Directors. As a result, Mr. Iseman controls both
Azimuth Technologies, L.P. and Azimuth Tech. II LLC. In addition, Mr. Iseman,
Steven M. Lefkowitz, a director of Anteon, and Robert A. Ferris, a director of
Anteon, are each employed by Caxton-Iseman Capital, Inc. Mr. Iseman is the
chairman, managing partner and founder of that firm.

                                       30


         Azimuth Technologies, L.P., Azimuth Tech. II LLC, Mr. Lefkowitz, SML
Family Investors LLC, a limited liability company affiliated with Mr. Lefkowitz,
and the Ferris Family 1987 Trust, of which Mr. Ferris is a trustee, entered into
a stockholders agreement immediately prior to the consummation of Anteon's
initial public offering, or "IPO". Under this stockholders agreement, the Ferris
Family 1987 Trust, Mr. Lefkowitz and SML Family Investors LLC agreed to vote all
of the shares of our common stock they beneficially own on any matter submitted
to the vote of our stockholders whether at a meeting or pursuant to a written
consent at the direction of Azimuth Technologies, L.P. and Azimuth Tech. II LLC,
unless otherwise agreed to by these entities, and will constitute and appoint
these entities or any nominees thereof as their respective proxies for purposes
of any stockholder vote. The agreement provides that none of the Ferris Family
1987 Trust, Mr. Lefkowitz or SML Family Investors LLC may sell or in any way
transfer or dispose of the shares of our common stock they beneficially own
without the prior written consent of either Azimuth Technologies, L.P. or
Azimuth Tech. II LLC, unless Azimuth Technologies, L.P. and Azimuth Tech. II LLC
are participating in that sale, and then the Ferris Family 1987 Trust, Mr.
Lefkowitz and SML Family Investors LLC may participate in such sale in a pro
rata amount. The Ferris Family 1987 Trust, Mr. Lefkowitz and SML Family
Investors LLC will be required to participate pro rata in any sale by Azimuth
Technologies, L.P. and Azimuth Tech. II LLC, unless otherwise agreed to by these
entities.

         REGISTRATION RIGHTS

         On March 11, 2002, Azimuth Technologies, L.P., Azimuth Tech. II LLC,
Messrs. Frederick J. Iseman, Joseph M. Kampf, Carlton B. Crenshaw, Thomas M.
Cogburn, Seymour L. Moskowitz and Steven M. Lefkowitz, SML Family Investors LLC
and the Ferris Family 1987 Trust and certain other parties named therein,
entered into a registration rights agreement (referred to in this proxy
statement as the "Registration Rights Agreement") with us relating to the shares
of common stock they hold. Subject to several exceptions, including our right to
defer a demand registration under certain circumstances, the Caxton-Iseman
Stockholders may require that we register for public resale under the Exchange
Act all shares of common stock they request be registered at any time after 180
days following our IPO. The Caxton-Iseman Stockholders may demand five
registrations so long as the securities being registered in each registration
statement are reasonably expected to produce aggregate proceeds of $5 million or
more. Since we are eligible to register the sale of our securities on Form S-3
under the Exchange Act, the Caxton-Iseman Stockholders have the right to require
us to register the sale of the common stock held by them on Form S-3, subject to
offering size and other restrictions. Messrs. Kampf, Crenshaw, Cogburn,
Moskowitz and Lefkowitz, SML Family Investors LLC and the Ferris Family 1987
Trust are entitled to piggyback registration rights with respect to any
registration request made by the Caxton-Iseman Stockholders. If the registration
requested by the Caxton-Iseman Stockholders is in the form of a firm
underwritten offering, and if the managing underwriter of the offering
determines that the number of securities to be offered would jeopardize the
success of the offering, the number of shares included in the offering shall be
determined as follows: (i) first, shares offered by the Caxton-Iseman
Stockholders and Messrs. Kampf, Crenshaw, Cogburn, Moskowitz and Lefkowitz, SML
Family Investors LLC, the Ferris Family 1987 Trust and the other participating
designated holders as defined in the Registration Rights Agreement (pro rata,
based on their respective ownership of our common equity), (ii) second, shares
offered by other stockholders (pro rata, based on their respective ownership of
our common equity) and (iii) third, shares offered by us for our own account. On
September 3, 2003, we amended the Registration Rights Agreement to (i) allow
certain of our stockholders and designated holders under the Registration Rights
Agreement, including Messrs. Decker, Kaminski, Schehr, Gurner, Dawson, Heilman,
Johnson and Ream and

                                       31


Ms. Centracchio, to participate in future offerings and (ii) permit us to
designate certain other management stockholders and directors to participate in
future offerings.

         In addition, the Caxton-Iseman Stockholders, Messrs. Kampf, Crenshaw,
Cogburn, Moskowitz and Lefkowitz, SML Family Investors LLC and the Ferris Family
1987 Trust and the other designated holders under the Registration Rights
Agreement have been granted piggyback rights on any registration for our account
or the account of another stockholder. If the managing underwriter in an
underwritten offering determines that the number of securities offered in a
piggyback registration would jeopardize the success of the offering, the number
of shares included in the offering shall be determined as follows: (i) first,
shares offered by us for own account, (ii) second, shares offered by the
Caxton-Iseman Stockholders, Messrs. Kampf, Crenshaw, Cogburn, Moskowitz and
Lefkowitz, SML Family Investors LLC, the Ferris Family 1987 Trust and the other
participating designated holders under the Registration Rights Agreement (pro
rata, based on their respective ownership of our common equity), and (iii)
third, shares offered by other stockholders (pro rata, based on their respective
ownership of our common equity). In connection with these registrations under
the Registration Rights Agreement, we are required to indemnify the selling
stockholders and bear all fees, costs and expenses (except underwriting
discounts and selling commissions).

         In August 2003, the Caxton-Iseman Stockholders exercised their right
requiring us to register their shares on a Form S-3 registration statement. In
addition, certain of the other parties to the registration rights agreement
exercised their rights thereunder to piggyback on the registration for the
accounts of the Caxton-Iseman Stockholders. As a result, we filed with the SEC a
registration statement on Form S-3 on August 22, 2003 and an amendment thereto
on September 4, 2003 (Commission File No. 333-108147), and a registration
statement on Form S-3 on September 16, 2003 (Commission File No. 333-108858). In
connection with the offering of these shares, the Caxton-Iseman Stockholders
reimbursed the Company for all fees, costs and expenses (except underwriting
discounts and selling commissions) incurred by the selling stockholders.

         In December 2003, the Caxton-Iseman Stockholders again exercised their
right requiring us to register their shares on a Form S-3 registration
statement. As a result, we filed with the SEC a registration statement on Form
S-3 on December 17, 2003 and an amendment thereto on March 2, 2004 (Commission
File No. 333-111249) (referred to collectively in this proxy statement as the
"Shelf Registration Statement"). The Ferris Family 1987 Trust, SML Family
Investors LLC and Mr. Lefkowitz exercised their rights to piggyback on the Shelf
Registration Statement, while all other parties with piggyback rights declined
to register their shares on the Shelf Registration Statement. We agreed to
indemnify the selling stockholders and bear all fees, costs and expenses (except
underwriting discounts and selling commissions) in connection with that
registration. The total fees, costs and expenses incurred by the Company in
connection with the Shelf Registration Statement were approximately $206,000.

         On October 29, 2004, the Caxton-Iseman Stockholders, sold 3,600,000
shares of our common stock in an underwritten offering pursuant to a shelf
registration statement on Form S-3 filed with the SEC (Commission File No.
333-111249). Neither we nor any of our executive officers participated in the
sale of shares in this offering. In connection with this offering, we incurred
$240,000 of expenses for the year ended December 31, 2004, for which we were not
reimbursed, in accordance with the terms of our registration rights agreement
with certain of our stockholders, as amended.

                                       32


         Pursuant to our registration rights agreement with the selling
stockholders, we will use our commercially reasonable efforts to keep the Shelf
Registration Statement continuously effective until all of the selling
stockholders' shares of our common stock have been sold. As of the date of this
proxy statement, no other offerings have been made pursuant to the Shelf
Registration Statement. Our obligation to keep the Shelf Registration Statement
effective is subject to specified, permitted exceptions, such as a good faith
determination by our Board of Directors that the registration would materially
interfere with certain activities of ours. In these cases, we may suspend offers
and sales of the shares of common stock pursuant to the Shelf Registration
Statement.

         OTHER RELATIONSHIPS

         The son of our President and Chief Executive Officer, Joseph M. Kampf,
has been employed by the Company as a Corporate Development Analyst since
January 2003 and received an annual salary of $64,431 in 2004.

DELISTING AND DEREGISTRATION OF ANTEON COMMON STOCK

         If the merger is completed, our common stock will no longer be traded
on the New York Stock Exchange and will be deregistered under the Securities
Exchange Act of 1934.

ACCOUNTING TREATMENT

         Anteon has been advised by General Dynamics that General Dynamics will
account for the merger under the purchase method of accounting for business
combinations under accounting principles generally accepted in the United
States.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

         GENERAL

         The following is a general discussion of the material U.S. federal
income tax consequences of the merger to U.S. holders (as defined below) of our
common stock. This summary is based on the provisions of the Internal Revenue
Code of 1986, as amended, which we refer to in this proxy statement as the
"Code", current and proposed U.S. Treasury Regulations, judicial authority, and
administrative rulings and practice, all of which are subject to change,
possibly on a retroactive basis and are subject to different interpretations.
There can be no assurance that the Internal Revenue Service will not challenge
one or more of the tax considerations described herein, and no ruling has been
sought from the Internal Revenue Service as to the U.S. federal income tax
consequences of the merger. For purposes of this discussion, the term "U.S.
holder" means any of the following holders of our common stock:

     o   a citizen or resident (as determined for U.S. federal income tax
         purposes) of the United States;

     o   a corporation, or other entity taxable as a corporation for U.S.
         federal income tax purposes, created or organized in or under the laws
         of the United States, any state within the United States, or the
         District of Columbia;

     o   a trust if it (1) is subject to the primary supervision of a court
         within the United States and one or more U.S. persons have the
         authority to control all substantial decisions of the

                                       33


         trust or (2) has a valid election in effect under applicable U.S.
         Treasury Regulations to be treated as a U.S. person; or

     o   an estate the income of which is subject to U.S. federal income tax
         regardless of its source.

         This discussion assumes that you hold your shares of our common stock
as a capital asset within the meaning of Section 1221 of the Code (generally,
property held for investment). This discussion does not address all aspects of
U.S. federal income taxation that may be relevant to you in light of your
particular circumstances, or that may apply to you if you are subject to special
treatment under the U.S. federal income tax laws (including, for example,
insurance companies, dealers or brokers in securities or foreign currencies,
tax-exempt organizations, financial institutions, mutual funds, partnerships or
entities treated as partnerships for U.S. federal income tax purposes, non-U.S.
stockholders, expatriates, persons subject to the alternative minimum tax,
persons who hold shares of our common stock as part of a hedge, straddle,
constructive sale or conversion transaction, or persons who acquired their
shares of our common stock through the exercise of employee stock options or
other compensation arrangements). In addition, the discussion does not address
any tax considerations under state, local or foreign laws or U.S. federal laws
(e.g. estate or gift tax laws) other than those pertaining to federal income
tax.

         If a partnership or other flow-through entity holds our common stock,
the U.S. federal income tax treatment of a partner or other owner generally will
depend on the status of the partner or other owner and the activities of the
partnership or other flow-through entity. A U.S. holder that is a partner of a
partnership or an owner of a different type of flow-through entity holding our
common stock should consult its own tax advisor.

         WE URGE YOU TO CONSULT YOUR TAX ADVISOR TO DETERMINE THE PARTICULAR TAX
CONSEQUENCES OF THE MERGER TO YOU, INCLUDING THE APPLICATION AND EFFECT OF ANY
STATE, LOCAL OR FOREIGN INCOME AND OTHER TAX LAWS.

         A U.S. holder's receipt of cash pursuant to the merger will be a
taxable transaction for U.S. federal income tax purposes (and also may be a
taxable transaction under applicable state, local and foreign income and other
tax laws). In general, for U.S. federal income tax purposes, a U.S. holder of
our common stock will recognize capital gain or loss equal to the difference
between:

     o   the amount of cash received in exchange for that common stock; and

     o   the U.S. holder's adjusted tax basis in that common stock.

         If your holding period for the shares of common stock surrendered in
the merger is greater than one year as of the date of the merger, the gain or
loss you recognize will be long-term capital gain or loss. Under current law,
non-corporate taxpayers generally are subject to a maximum regular U.S. federal
income tax rate of 15% on net long-term capital gains. The deductibility of a
capital loss is subject to certain limitations under the Code. If you acquired
different blocks of common stock at different times and different prices, you
must determine your adjusted tax basis and holding period separately with
respect to each block of common stock.

         INFORMATION REPORTING AND TAX WITHHOLDING

                                       34


         You may be subject to information reporting on IRS Form 1099 on the
cash you receive pursuant to the merger unless you are a corporation or
otherwise exempt from information reporting.

         Backup withholding (currently at a rate of 28%) will also apply to the
amount of cash you receive pursuant to the merger, unless you provide proof of
an applicable exemption or a correct taxpayer identification number on IRS Form
W-9, and otherwise comply with the applicable requirements of the backup
withholding rules. Backup withholding is not an additional tax, and any amounts
withheld under the backup withholding rules may be refunded or credited against
your U.S. federal income tax liability, if any, provided that you furnish the
required information to the Internal Revenue Service in a timely manner.

REGULATORY APPROVALS

         Other than approval pursuant to the HSR Act, no other material federal
or state regulatory approvals are required to be obtained by us, General
Dynamics or Merger Sub in connection with the merger. On January o, 2006, Anteon
and General Dynamics each filed a Notification and Report Form with the
Antitrust Division of the Department of Justice and the Federal Trade
Commission. Under the HSR Act and related rules, the merger may not be completed
until the expiration or termination of the statutory waiting period. The waiting
period is scheduled to expire at 12:00 A.M. on February ?, 2006, unless
extended.

AMENDMENT TO ANTEON'S RIGHTS AGREEMENT

         In connection with the signing of the merger agreement, Anteon also
amended its rights agreement with American Stock Transfer & Trust Company to
provide that the preferred stock purchase rights issued under the rights
agreement will not become exercisable nor will any holder of any preferred stock
purchase right be entitled to exercise any other rights described in the
agreement because of:

     o   the approval, execution or delivery of the merger agreement or any
         amendments of the merger agreement; or

     o   the consummation of the merger.

         Among other things, the amendment also provides that the preferred
stock purchase rights will expire immediately prior to the effective time of the
merger.

APPRAISAL RIGHTS

         Pursuant to Section 262 of the DGCL, any Anteon stockholder who does
not wish to accept the $55.50 merger consideration may demand appraisal of his
or her shares of Anteon common stock and have the fair value of such shares
(exclusive of any element of value arising from the accomplishment or
expectation of the merger) judicially determined by the Delaware Court of
Chancery and paid to the stockholder in cash, together with a fair rate of
interest, if any, provided that the stockholder complies with the provisions of
Section 262 of the DGCL. The following discussion is not a complete statement of
the law pertaining to appraisal rights under the DGCL and is qualified in its
entirety by the full text of Section 262 of the DGCL, which is attached to this
proxy statement as EXHIBIT C. The following summary does not constitute any
legal or other advice, nor does it constitute a recommendation that stockholders
exercise their appraisal rights under Section 262 of the DGCL. All references in
Section 262 of the DGCL and

                                       35


in this summary to a "stockholder" are to the record holder of the shares of
Anteon common stock as to which appraisal rights are asserted. A person having a
beneficial interest in shares of Anteon common stock held of record in the name
of another person, such as a broker or nominee, must act promptly to cause the
record holder to follow properly and in a timely manner the steps summarized
below to perfect appraisal rights. Because of the complexity of the appraisal
procedures, Anteon believes that stockholders who consider exercising these
rights should seek the advice of counsel.

         Under Section 262 of the DGCL, where a merger is to be submitted for
approval at a meeting of stockholders, as in the case of the adoption of the
merger agreement by Anteon's stockholders, the corporation, not less than 20
days prior to the meeting, must notify each of its stockholders entitled to
appraisal rights that appraisal rights are available and include in the notice a
copy of Section 262 of the DGCL. This proxy statement shall constitute the
notice, and the applicable statutory provisions are attached to this proxy
statement as EXHIBIT C. Any Anteon stockholder who wishes to exercise appraisal
rights or who wishes to preserve such stockholder's right to do so, should
review the following discussion and EXHIBIT C carefully because failure to
timely and properly comply with the procedures specified will result in the loss
of appraisal rights.

         Stockholders wishing to seek an appraisal of their shares must do ALL
of the following:

     o   The stockholder must not vote in favor of the adoption of the merger
         agreement and approval of the merger. Moreover, because a signed proxy
         that does not contain voting instructions will, unless revoked, be
         voted in favor of adoption of the merger agreement and approval of the
         merger, a stockholder who votes by proxy and who wishes to exercise
         appraisal rights must vote against adoption of the merger agreement and
         approval of the merger;

     o   The stockholder must deliver to Anteon a written demand for appraisal
         BEFORE the vote on the adoption of the merger agreement and approval of
         the merger at the special meeting;

     o   The stockholder must continuously hold the shares from the date of
         making the demand through the effective time of the merger since
         appraisal rights will be lost if the shares are transferred before the
         effective time of the merger; and

         Within 120 days after the effective time of the merger, but not
thereafter, Anteon, or any Anteon stockholder who has complied with the
procedures under Section 262 of the DGCL and who is entitled to appraisal rights
under Section 262 of the DGCL, may file a petition in the Delaware Court of
Chancery demanding a determination of the value of the stock of all such
stockholders. Anteon is not under any obligation to file a petition seeking the
appraisal of the shares of Anteon common stock. Accordingly, it is the
obligation of the stockholders to initiate all necessary action to perfect their
appraisal rights within the time prescribed in Section 262 of the DGCL.

         Neither voting (in person or by proxy) against, abstaining from voting
on or failing to vote on the proposal to adopt the merger agreement and approve
the merger will constitute a written demand for appraisal within the meaning of
Section 262 of the DGCL. The written demand for appraisal must be in addition to
and separate from any proxy or vote.

         Only a holder of record of shares of Anteon common stock issued and
outstanding immediately prior to the effective time of the merger may assert
appraisal rights for the shares of

                                       36


Anteon common stock registered in that holder's name. A demand for appraisal
should be executed by or on behalf of the stockholder of record, fully and
correctly, as the stockholder's name appears on the stock certificates, should
specify the stockholder's name and mailing address, the number of shares of
Anteon common stock owned and that the stockholder intends to demand appraisal
of his or her Anteon common stock. If the shares are owned of record in a
fiduciary capacity, such as by a trustee, guardian or custodian, execution of
the demand should be made in that capacity, and if the shares are owned of
record by more than one person, as in a joint tenancy and tenancy in common, the
demand should be executed by or on behalf of all joint owners. An authorized
agent, including an agent for two or more joint owners, may execute a demand for
appraisal on behalf of a holder or record; however, the agent must identify the
record owner or owners and expressly disclose that, in executing the demand, the
agent is acting as agent for the record owner or owners. If the shares are held
in "street name" by a broker, bank or nominee, the broker, bank or nominee may
exercise appraisal rights with respect to the shares held for one or more
beneficial owners while not exercising the rights with respect to the shares
held for other beneficial owners; in such case, however, the written demand
should set forth the number of shares as to which appraisal is sought and where
no number of shares is expressly mentioned the demand will be presumed to cover
all shares of common stock of Anteon held in the name of the record owner.
Stockholders who hold their shares in brokerage accounts or other nominee forms
and who wish to exercise appraisal rights are urged to consult with their
brokers to determine the appropriate procedures for the making of a demand for
appraisal by that nominee.

         A stockholder who elects to exercise appraisal rights pursuant to
Section 262 of the DGCL should mail or deliver a written demand to: Curtis L.
Schehr, Secretary, Anteon International Corporation, 3211 Jermantown Road,
Fairfax, Virginia 22030-2801.

         If the merger agreement is adopted and the merger is approved, Anteon
will give written notice of the effective time of the merger within 10 days
after the effective time of the merger to each former stockholder of Anteon who
did not vote in favor of the adoption of the merger agreement and approval of
the merger and who made a written demand for appraisal in accordance with
Section 262 of the DGCL. Within 120 days after the effective time of the merger,
but not later, either the surviving company or any dissenting stockholder who
has complied with the requirements of Section 262 of the DGCL may file a
petition in the Delaware Court of Chancery demanding a determination of the
value of the shares of Anteon common stock held by all dissenting stockholders.
As there is no present intention to have the surviving company file such a
petition, stockholders who desire to have their shares appraised should initiate
any petitions necessary for the perfection of their appraisal rights within the
time periods and in the manner prescribed in Section 262 of the DGCL. If a
petition for appraisal is not timely filed, then the right to an appraisal will
cease.

         Under the merger agreement, Anteon has agreed to give General Dynamics
prompt notice of any demands for appraisal received by it, withdrawals of those
demands and any other communications delivered to Anteon pursuant to Section 262
of the DGCL. General Dynamics will have the opportunity to participate in all
negotiations and proceedings with respect to demands for appraisal under the
DGCL. Anteon will not, except with the prior written consent of General
Dynamics, settle, offer to settle or make any payment with respect to any
demands for appraisal.

         Within 120 days after the effective time of the merger, any stockholder
who has complied with the provisions of Section 262 of the DGCL to that point in
time will be entitled to receive from the surviving company, upon written
request, a statement setting forth the aggregate number

                                       37


of shares not voted in favor of the merger agreement and with respect to which
demands for appraisal have been received and the aggregate number of holders of
those shares. The surviving company must mail this statement to the stockholder
within 10 days of receipt of the request or within 10 days after expiration of
the period for delivery of demands for appraisal under Section 262 of the DGCL,
whichever is later.

         If a petition for appraisal is timely filed, the Delaware Court of
Chancery will determine which stockholders are entitled to appraisal rights and
may require the stockholders demanding appraisal who hold certificated shares to
submit their stock certificates to the court for notation of the pendency of the
appraisal proceedings, and if the stockholder fails to comply with the court's
direction, the court may dismiss the proceeding as to the stockholder. The
Delaware Court of Chancery will thereafter determine the fair value of the
shares of Anteon common stock held by dissenting stockholders, exclusive of any
element of value arising from the accomplishment or expectation of the merger,
but together with a fair rate of interest, if any, to be paid on the amount
determined to be fair value. In determining the fair value, the Delaware Court
of Chancery will take into account all relevant factors. The Delaware Supreme
Court has stated that "proof of value by any techniques or methods which are
generally considered acceptable in the financial community and otherwise
admissible in court" should be considered in the appraisal proceedings. The
Delaware Court of Chancery may determine the fair value to be more than, less
than or equal to the consideration that the dissenting stockholder would
otherwise be entitled to receive under the merger agreement. The costs of the
appraisal proceeding will be determined by the Delaware Court of Chancery and
taxed against the parties as the Delaware Court of Chancery determines to be
equitable under the circumstances. Upon application of a stockholder, the
Delaware Court of Chancery may order all or a portion of the expenses incurred
by any stockholder in connection with the appraisal proceeding, including,
without limitation, reasonable attorneys' fees and the fees and expenses of
experts, to be charged PRO RATA against the value of all shares entitled to
appraisal.

         STOCKHOLDERS SHOULD BE AWARE THAT THE FAIR VALUE OF THEIR SHARES AS
DETERMINED UNDER SECTION 262 OF THE DGCL COULD BE GREATER THAN, THE SAME AS, OR
LESS THAN THE $55.50 MERGER CONSIDERATION. THE BEAR STEARNS OPINION IS NOT AN
OPINION AS TO FAIR VALUE UNDER SECTION 262 OF THE DGCL.

         Any stockholder who has duly demanded an appraisal in compliance with
Section 262 of the DGCL will not, after the effective time of the merger, be
entitled to vote the shares subject to the demand for any purpose or be entitled
to the payment of dividends or other distributions on those shares (except
dividends or other distributions payable to holders of record of shares as of a
record date prior to the effective time of the merger).

         Any stockholder may withdraw a demand for appraisal and accept the
merger consideration by delivering to the surviving company a written withdrawal
of the demand for appraisal, except that (1) any attempt to withdraw made more
than 60 days after the effective time of the merger will require written
approval of the surviving company and (2) no appraisal proceeding in the
Delaware Court of Chancery will be dismissed as to any stockholder without the
approval of the Delaware Court of Chancery, and the approval may be conditioned
upon terms the Delaware Court of Chancery deems just. If the stockholder fails
to perfect, successfully withdraws or loses the appraisal right, the
stockholder's shares will be converted into the right to receive the merger
consideration. A stockholder will fail to perfect, or effectively lose or
withdraw, the holder's right to appraisal if no petition for appraisal is filed
within 120 days after the effective time of the transaction or if the
stockholder delivers to the surviving company a

                                      38


written withdrawal of the holder's demand for appraisal and an acceptance of the
transaction in accordance with Section 262 of the DGCL.

                              THE MERGER AGREEMENT

         The following summary of the terms of the merger agreement is qualified
in its entirety by reference to the full text of the merger agreement, which is
attached as EXHIBIT A to this proxy statement and is incorporated herein by
reference. We encourage you to read the entire merger agreement. The merger
agreement has been included to provide investors and security holders with
information regarding its terms. It is not intended to provide any other factual
information about the Company, the equity investors or their respective
affiliates.

FORM OF THE MERGER

         The merger agreement provides that at the effective time of the merger,
Merger Sub will be merged with and into Anteon. As a result of the merger, the
separate corporate existence of Merger Sub will cease and Anteon will continue
as the surviving company following the merger as a wholly-owned indirect
subsidiary of General Dynamics. Anteon, as the surviving company, will succeed
to all the properties, rights, privileges, powers, franchises and assets, and
all debts, liabilities and duties of Anteon and Merger Sub.

EFFECTIVE TIME OF THE MERGER

         The merger agreement provides that the merger will become effective
when we file a certificate of merger with the Secretary of State of the State of
Delaware, or at such later time that we and General Dynamics specify in the
certificate of merger. We will file the certificate of merger at the closing of
the merger, which will take place no later than the second business day
following the satisfaction or the waiver of the conditions set forth in the
merger agreement or at such other time as we and General Dynamics agree in
writing.

DIRECTORS AND OFFICERS

         The directors and officers of Merger Sub at the effective time of the
merger will be the initial directors and officers of the surviving company. The
directors and officers will serve in accordance with the certificate of
incorporation and bylaws of the surviving company.

MERGER CONSIDERATION

         The merger agreement provides that each share of common stock of Anteon
(other than shares owned by Anteon, General Dynamics or Merger Sub, or any of
their respective subsidiaries, and dissenting shares) issued and outstanding
immediately prior to the effective time of the merger will be cancelled and
automatically converted into the right to receive an amount in cash equal to
$55.50, less any required withholding taxes and without interest. Each share of
common stock of Anteon that is owned by Anteon, General Dynamics or Merger Sub,
or any of their respective subsidiaries, will be cancelled and extinguished at
the effective time of the merger and no consideration will be delivered in
exchange for those shares. If appraisal rights for any of Anteon's shares are
perfected by any Anteon stockholder, those shares will be treated as described
in the section entitled "The Merger--Appraisal Rights."

                                       39


PAYMENT PROCEDURES

         Prior to the effective time of the merger, General Dynamics will
appoint a paying agent approved by us. No later than three business days
following the effective time of the merger, General Dynamics will instruct the
paying agent to mail to each stockholder a letter of transmittal and
instructions explaining how to surrender stock certificates or execute an
appropriate instrument of transfer of your shares of Anteon common stock in
exchange for the merger consideration. Upon surrender of a certificate or
appropriate instrument of transfer representing shares of Anteon common stock to
the paying agent, together with a duly executed and completed letter of
transmittal and all other documents required by the paying agent, each former
stockholder of Anteon will be entitled to receive $55.50 for each share of
Anteon common stock so surrendered.

EFFECT ON STOCK OPTIONS, STOCK-BASED AWARDS AND EMPLOYEE STOCK PURCHASE PLAN

         The merger agreement provides that each outstanding option to acquire
shares of common stock of Anteon granted under the Amended and Restated Anteon
International Corporation Omnibus Stock Plan will become fully vested
immediately prior to the effective time of the merger and will be cancelled at
the effective time of the merger. Each option holder will have the right to
receive, within five business days of the effective time of the merger, a cash
payment (less any required withholding taxes and without interest) equal to the
product of (1) the excess, if any, of $55.50 over the applicable exercise price
per share of the option and (2) the number of shares of common stock of Anteon
issuable upon exercise of the option (whether or not the option is vested or
exercisable).

         The merger agreement provides that all other stock-based awards
outstanding immediately prior to the effective time of the merger (including
restricted stock and performance shares or awards) will become fully vested by
virtue of the merger and each holder of an award will have the right to receive,
within five business days of the effective time of the merger, a cash payment
(less any required withholding taxes and without interest) equal to the product
of (1) $55.50 and (2) the number of shares subject to the award.

         The merger agreement provides that the Anteon International Corporation
Employee Stock Purchase Plan (and any offering period under the plan) is to be
terminated at the effective time of the merger and no offering period (as
defined under the plan) will commence following the date of the merger
agreement. Under the merger agreement, each participant in the plan will receive
for any option under the plan outstanding at the effective time of the merger,
in lieu of any other consideration, within five business days of the effective
time of the merger, a cash payment (less any required withholding taxes and
without interest) equal to the sum of (1) $55.50 multiplied by the number of
whole shares of the common stock of Anteon that would have been issued upon
exercise of such options had they been exercised at the effective time of the
merger and the participant had purchased the maximum number of shares using the
full amount of his or her "contributions" (as defined under the plan) and (2)
any such "contributions" that would not have been sufficient to purchase a whole
share.

REPRESENTATIONS AND WARRANTIES

         The merger agreement contains representations and warranties made by
Anteon, including, but not limited to, representations and warranties relating
to:

     o   corporate organization, authority to conduct business and standing;

                                       40


     o   capitalization;

     o   corporate power and authority to enter into and perform our obligations
         under, and enforceability of, the merger agreement;

     o   voting standard required for stockholder approval of the merger;

     o   conflicts or violations under charter documents, contracts, instruments
         or laws, required consents or approvals and creation or imposition of
         any liens;

     o   reports, proxy statements and financial statements filed with the
         Securities and Exchange Commission, the accuracy of the information in
         those documents, internal control over financial reporting, disclosure
         controls and procedures and required certifications with respect
         thereto;

     o   absence of undisclosed liabilities;

     o   absence of certain events and changes;

     o   litigation matters and compliance with laws;

     o   material contracts, government contracts and performance thereunder;

     o   tax matters;

     o   employee benefit matters;

     o   environmental matters;

     o   owned and leased real property;

     o   intellectual property matters;

     o   labor matters;

     o   amendment of the rights agreement;

     o   applicability of certain takeover laws and our satisfaction of the
         requirements under those laws;

     o   insurance;

     o   broker's and finders' fees; and

     o   receipt of an opinion from our financial advisor.

         Many of the above representations and warranties were qualified by a
material adverse effect standard. A material adverse effect for purposes of our
representations and warranties means any event, circumstance, condition, change,
development or effect that, individually or in the aggregate, would have a
material adverse effect on the business, financial condition, assets,

                                       41


liabilities, operations or results of operations of us and our subsidiaries
taken as a whole, or on our ability to consummate the merger and perform our
obligations under the merger agreement.

         In determining whether a material adverse effect has occurred, none of
the following are taken into account:

     o   conditions affecting any of the industries in which Anteon or its
         subsidiaries operate generally;

     o   conditions generally affecting the economy or capital markets;

     o   changes in Anteon's stock price or trading volume (although the facts
         or occurrences giving rise to or contributing to a change in Anteon's
         stock price or trading volume may be taken into account to determine
         whether there has been a material adverse effect); or

     o   the announcement, pendency or consummation of the merger.

         The merger agreement contains representations and warranties made by
General Dynamics and Merger Sub including, but not limited to, representations
and warranties relating to:

     o   corporate organization, authority to conduct business and standing;

     o   corporate power and authority to enter into and perform their
         respective obligations under, and enforceability of, the merger
         agreement;

     o   conflicts or violations under charter documents or laws, and required
         consents or approvals;

     o   availability of funds to perform its obligations under the merger
         agreement, including payment of the merger consideration and amounts
         payable in respect of stock options and other awards;

     o   information in this proxy statement supplied by General Dynamics or
         Merger Sub expressly for inclusion herein;

     o   litigation matters; and

     o   absence of brokers' and finders' fees.

         The representations and warranties of the parties will expire at the
effective time of the merger.

         The merger agreement contains representations and warranties that the
parties to the agreement made to and solely for the benefit of each other. The
assertions embodied in the representations and warranties made by Anteon are
qualified by information in a confidential disclosure letter that Anteon
delivered to General Dynamics in connection with signing the merger agreement.
While Anteon does not believe that the disclosure letter contains non-public
information that the securities laws require to be publicly disclosed, the
disclosure letter does contain information that modifies, qualifies and creates
exceptions to the representations and warranties set forth in the merger
agreement. Accordingly, you should not rely on the

                                       42


representations and warranties as characterizations of the actual state of
facts, because (i) they were only made as of the date of the merger agreement or
a prior, specified date, (ii) in some cases they are subject to materiality,
material adverse effect or knowledge qualifiers, and (iii) they are modified in
important part by the confidential disclosure letter. The confidential
disclosure letter contains information that has been included in Anteon's prior
public disclosures, as well as non-public information. Moreover, information
concerning the subject matter of the representations and warranties may have
changed since the date of the merger agreement, which subsequent information may
or may not be fully reflected in Anteon's public disclosures.

CONDUCT OF BUSINESS PENDING THE MERGER

         From the date of the merger agreement until the effective time of the
merger or the termination of the merger agreement, unless General Dynamics
otherwise agrees in writing, Anteon and its subsidiaries will:

     o   conduct their operations in accordance with their ordinary course of
         business consistent with past practice; and

     o   use reasonable efforts to preserve intact their business organization,
         keep available the services of their current officers and employees,
         preserve the goodwill of those having business relationships with them,
         preserve their relationships with customers, creditors and suppliers,
         maintain their books, accounts and records and comply in all material
         respects with applicable laws.

           Anteon also agreed that, until the effective time of the merger,
neither it nor its subsidiaries will take any of the following actions without
the prior written consent of General Dynamics:

     o   amend or propose to amend its certificate of incorporation or bylaws or
         file any certificate of designation or similar instrument with respect
         to any authorized but unissued capital stock;

     o   split, combine or reclassify any shares of its capital stock, amend the
         terms of any outstanding securities or repurchase, redeem or acquire
         any shares of capital stock;

         dividends payable by a wholly-owned subsidiary of Anteon to Anteon or
         another wholly-owned subsidiary;

     o   authorize for issuance, issue, sell or grant any capital stock or any
         options or other securities or rights to acquire capital stock or which
         are exchangeable for or convertible into capital stock other than in
         connection with the exercise of options outstanding on the date of the
         merger agreement or in connection with any offering period under the
         employee stock purchase plan that has commenced prior to the date of
         the merger agreement, or repurchase, redeem or otherwise acquire any
         shares of capital stock or any other securities exercisable or
         exchangeable for or convertible into capital stock;

     o   merge or consolidate, liquidate, dissolve, recapitalize or reorganize,
         or create any new subsidiary;

     o   sell, lease, license, pledge, encumber or otherwise dispose of any
         material assets or interests, except in the ordinary course of
         business, consistent with past practice;

     o   acquire any assets other than in the ordinary course of business,
         consistent with past practice;

     o   acquire any equity interest in any entity or any business, or enter
         into any joint venture, strategic alliance or other similar arrangement
         with another entity, other than teaming or other similar agreements
         entered into in the ordinary course of business, consistent with past
         practice;

     o   incur, assume or guarantee any indebtedness (including the issuance of
         debt securities) other than under Anteon's existing credit lines,
         intercompany indebtedness or in the ordinary course of business,
         consistent with past practice;

     o   except as required by changes in law or GAAP, change any of Anteon's
         accounting principles or practices used as of September 30, 2005 that
         would reasonably be expected to materially affect the assets,
         liabilities, or results of operation of Anteon or its subsidiaries;

     o   except in the ordinary course of business, consistent with past
         practice, make or change any material tax election, settle or
         compromise any material tax liability, change in any material respect
         any accounting method in respect of taxes, file any amendment to a
         material tax return, settle any material claim or material assessment
         in respect of taxes, or consent to any extension or waiver of the
         limitation period applicable to any claim or assessment in respect of
         taxes;

     o   except as required under any existing agreement and other than

         past practices or pursuant to certain written agreements identified in
         the confidential disclosure letter delivered by Anteon to General

         the ordinary course of business, consistent with past practice;

     o   waive, release or assign any material rights, claims or benefits under

         any of their respective subsidiaries from engaging in any line of
         business, competing with any entity or selling any product or service;

                                       44


     o   engage in any "reportable transaction," including any "listed

OTHER PROPOSALS

         We have agreed to certain limitations on our ability to take action
with respect to other acquisition proposals prior to the effective time of the
merger. Notwithstanding these limitations, we may respond to certain proposals
prior to the adoption of the merger agreement and approval of the merger by our
stockholders. The merger agreement provides that:

     o   the term "acquisition proposal" means any inquiry, proposal, indication
         of interest or offer relating to an acquisition or sale of 20% or more
         of Anteon's consolidated assets or 20% or more of Anteon's or its
         subsidiaries' equity securities, a tender or exchange offer that would
         result in any one person or entity beneficially owning 20% or more of
         Anteon's or any of its subsidiaries' equity securities, or a merger,
         consolidation, business combination, reorganization, recapitalization,
         liquidation, dissolution or other similar transaction other than the
         merger of Anteon and Merger Sub contemplated by the merger agreement;
         and

     o   the term "superior proposal" means an unsolicited, bona fide, written
         acquisition proposal not received in violation of the following
         paragraph for at least a majority of Anteon's outstanding common stock
         or all or substantially all of its consolidated assets which is fully
         financed or for which financing is reasonably likely to be available
         and on terms that Anteon's board of directors determines in good faith
         would result in a transaction that is more favorable to Anteon's
         stockholders from a financial point of view than the merger with Merger
         Sub and is reasonably capable of being completed according to its
         terms.

         The merger agreement provides that, prior to the effective time, Anteon
and its representatives may not:

     o   solicit, initiate, facilitate or knowingly encourage the making or
         submission of any acquisition proposal;

     o   enter into any letter of intent, agreement, arrangement or
         understanding with respect to any acquisition proposal, or agree to
         approve or endorse any acquisition proposal or enter into any
         agreement, arrangement or understanding that would require Anteon to
         abandon, terminate or fail to consummate the merger;

     o   initiate or participate in any discussions or negotiations or furnish
         or disclose information in furtherance of a proposal that constitutes
         or could lead to an acquisition proposal; or

                                       45


     o   facilitate any inquiries or the making or the submission of a proposal
         that constitutes or could reasonably be expected to lead to an
         acquisition proposal.

         Prior to the adoption of the merger agreement and approval of the
merger by our stockholders, Anteon is permitted to engage in discussions and
negotiations with respect to an unsolicited, bona fide acquisition proposal and
furnish information about itself and its subsidiaries to the party making such a
proposal pursuant to a customary confidentiality agreement that is at least as
restrictive on the other party as the confidentiality agreement between Anteon
and General Dynamics if:

     o   Anteon has not violated its obligations as described in the preceding
         paragraph; and

     o   Anteon's board of directors determines in good faith, after consulting
         with its financial advisor and outside legal counsel, that the
         acquisition proposal is, or is reasonably likely to result in, a
         superior proposal and that failure to provide such information, or
         engage in such discussions or negotiations regarding the acquisition
         proposal would result in a breach of the fiduciary duties of Anteon's
         board of directors to Anteon's stockholders under applicable law.

         In addition, the merger agreement provides that Anteon will:

     o   notify General Dynamics of any acquisition proposal or any request for
         information or inquiry that could reasonably be expected to lead to an
         acquisition proposal within 48 hours of receiving such proposal or
         inquiry, which notification will include a copy or summary of the
         acquisition proposal or inquiry, including the identity of the third
         party making such acquisition proposal or inquiry;

     o   keep General Dynamics advised on a reasonably current basis as to the
         status and content of any discussions or negotiations involving any
         acquisition proposal or inquiry and promptly make available to General
         Dynamics any non-public information furnished in connection with such
         acquisition proposal or inquiry that has not been previously provided
         to General Dynamics; and

     o   notify General Dynamics in writing promptly after any determination by
         Anteon's board of directors that an acquisition proposal is, or would
         reasonably be likely to result in or lead to a superior proposal.

         Neither Anteon's board of directors nor any committee thereof may
withdraw, modify or change, or propose publicly to withdraw, modify or change,
its recommendation regarding the merger in a manner adverse to General Dynamics,
Merger Sub or the transactions contemplated by the merger agreement unless,
prior to obtaining stockholder approval, Anteon's board of directors determines
in good faith, after consultation with its outside legal counsel, that failing
to do so would be a breach of the fiduciary duties of Anteon's board of
directors to Anteon's stockholders. If Anteon's board of directors withdraws,
modifies or changes, or proposes publicly to withdraw, modify or change, its
recommendation in response to a superior proposal, Anteon has agreed to give
General Dynamics four business days written notice of the material terms and
provisions of the superior proposal and to negotiate in good faith with General
Dynamics during that period to amend the merger agreement so that the
acquisition proposal is no longer a superior proposal. If at the end of such
four business day period, Anteon's board of directors continues to believe in
good faith, after receiving the advice of its outside legal counsel and
financial advisors, that the acquisition proposal continues to be a superior
proposal, and

                                       46


Anteon satisfies its obligations to pay any termination fee and make any expense
reimbursement, then it may withdraw, modify or change its recommendation by
written notice to General Dynamics and terminate the merger agreement.

EMPLOYEE BENEFITS

         The merger agreement provides that General Dynamics will, for a period
beginning on the date the merger closes and ending on December 31, 2007, provide
Anteon employees with compensation and other benefits that are no less favorable
than the compensation and benefits provided to them immediately prior to the
closing of the merger. Starting on January 1, 2007, General Dynamics may satisfy
this obligation by providing compensation and benefits on substantially the same
basis as are provided to similarly situated employees of General Dynamics
Network Systems, Inc., an indirect wholly-owned subsidiary of General Dynamics.

         The merger agreement provides that General Dynamics will waive all
limitations as to pre-existing conditions, exclusions and waiting periods under
any welfare or fringe benefit plan in which Anteon employees may be eligible to
participate after the closing date of the merger and will provide each Anteon
employee with credit under any general leave, welfare or fringe benefit plan in
which the employee becomes eligible to participate after the closing date for
any co-payments and deductibles paid by such employee for the then current plan
year under the corresponding plan maintained by Anteon prior to the date of
closing.

         The merger agreement provides that General Dynamics will honor all
severance agreements in effect on the date of the merger agreement. The merger
agreement also provides that General Dynamics will honor and satisfy all
commitments with respect to Anteon's annual incentive bonuses payable for 2005
in accordance with Anteon's compensation plans in effect on the date of the
agreement.

         The merger agreement contains a number of mutual covenants of Anteon
and General Dynamics, including covenants relating to:

     o   actions relating to anti-takeover statutes;

     o   preparing and filing this proxy statement, the inclusion in the proxy

         the information furnished to each other for inclusion in the proxy
         statement;

     o   making public announcements in connection with the merger;

     o   notifying the other party of certain events and supplementing

         period under the HSR Act has not expired or terminated) unless the

         party's material breach of the merger agreement;

     o   by either General Dynamics or Anteon if there are any laws that
         prohibit the merger, or if a final and non-appealable order, decree,

         occurred: (i) the waiting period applicable to the consummation of the

     o   by Anteon if prior to obtaining stockholder approval of the merger, the

         termination of the merger agreement Anteon pays the required
         termination fee and expense reimbursement to General Dynamics;

Anteon's 2006 annual meeting, if such a meeting is held, written notice of any
stockholder proposal must have been received by the Company not later than
December 22, 2005. To be considered for presentation at Anteon's annual meeting,
if such a meeting is held, stockholder proposals must be received at Anteon's
executive office no more than 90 nor less than 60 days prior to the anniversary
of the 2005 annual meeting; as a result, proposals must be received between
January 25, 2006 and February 24, 2006. All stockholder proposals for inclusion
in Anteon's future annual meeting proxy materials, if any, will be subject to
the requirements of the proxy rules adopted under the Securities Exchange Act of
1934, as amended, and, as with any stockholder proposal (regardless of whether
it is included in Anteon's proxy materials), Anteon's certificate of
incorporation and by-laws, and Delaware law.

the special meeting, proxy holders will, in their discretion, vote thereon in
accordance with their best judgment.
