     Re:  HOW THE GENERAL DYNAMICS
          ACQUISITION WILL AFFECT YOUR ANTEON STOCK OPTIONS
          -------------------------------------------------

Dear Optionholder:

         As you are likely aware,  on December 13, 2005,  Anteon  International
Corporation  ("Anteon" or the "Company")  entered into an agreement and plan of
merger with General  Dynamics  Corporation  ("General  Dynamics"),  pursuant to
which Anteon will, in a merger transaction (the "MERGER"),  become a subsidiary
of  General  Dynamics.  Our  records  indicate  that  you  are  the  holder  of
outstanding stock options ("ANTEON OPTIONS") to purchase shares of common stock
of  Anteon,   which  were  granted  under  the  Amended  and  Restated   Anteon
International  Corporation  Omnibus Stock Plan. This letter  addresses how your
Anteon  Options  will be affected  by the  potential  acquisition  of Anteon by
General  Dynamics.  Please  keep in mind that there are a number of  conditions
which must be  satisfied  before  the  Merger can close,  all of which are more
fully  described  in the  proxy  statement  related  to the  Merger,  which  is
available on Anteon's  website  (WWW.ANTEON.COM)  under Investor  Relations/SEC
Filings.  If the  Merger  does  not  close,  you  will  continue  to hold  your
unexercised Anteon Options.

         PLEASE NOTE THAT AS AN  OPTIONHOLDER,  YOU ARE NOT ENTITLED TO VOTE ON
THE MERGER OR THE MERGER  AGREEMENT.  OF COURSE,  IF YOU OWN ANTEON STOCK,  YOU
WILL BE ENTITLED TO VOTE ALONG WITH THE OTHER STOCKHOLDERS, AS DESCRIBED IN THE
PROXY STATEMENT.


A.       EFFECT OF THE MERGER ON VESTED AND UNVESTED ANTEON OPTIONS

         VESTED  OPTIONS.  In  connection  with the Merger,  all VESTED  ANTEON
OPTIONS  outstanding  immediately  prior  to the  closing  of the  Merger  will
automatically be cancelled and all rights with respect to those options will be
cancelled.  You will  receive for each of your vested  Anteon  Options  that is
cancelled  an amount,  subject to  applicable  tax  withholdings,  equal to the
PRODUCT OF (A) the amount of cash to be received  for a share of Anteon  common
stock in the Merger  ($55.50) MINUS the per share exercise price of your vested
Anteon  Options and (B) the number of shares of Anteon  common stock subject to
your vested  Anteon  Options.  You do not need to do  anything to receive  this
"cash out" payment in  cancellation  of your Anteon  Options.  Anteon will make
this payment to you through its payroll  operations  within five  business days
after the effective  date of the Merger.  This payment will be fully taxable to
you as  compensation  income,  and payroll taxes and income taxes  withholdings
will apply.

         UNVESTED OPTIONS.  In connection with the Merger,  all UNVESTED ANTEON
OPTIONS  outstanding  immediately prior to the closing of the Merger will fully
vest as of the  closing and all rights with  respect to those  options  will be
cancelled.  You will  receive a payment in respect of those  unvested  options,
calculated as described  above for vested Anteon  Options,  subject to the same
tax withholdings  described in the preceding paragraph.  Again, you do not need
to do anything to receive this "cash out" payment.  If this process  begins and
for some reason the Merger does not close,  the  vesting  acceleration  will be
reversed  and your  unvested  option's  vesting  schedule  will  return  to its
original dates.


B.       EXERCISING OPTIONS THAT QUALIFY
         AS INCENTIVE STOCK OPTIONS BEFORETHE MERGER

         If any of your vested  Anteon  Options  are  incentive  stock  options
(commonly  referred to as ISOs), you may be able to achieve some tax savings by
exercising  those vested options prior to the closing of the Merger.  These tax
savings may be possible  because  ISOs are not subject to Social  Security  and
Medicare taxes, known as FICA taxes, when exercised, or when the stock acquired
through the exercise of an ISO is subsequently sold. For your information,  the
employee  portion of FICA taxes is 7.65% of the first  $94,200 of  compensation
received during a year and 1.45% of all amounts of compensation received during
a year.

         TAX MATTERS ARE  COMPLEX  AND THE TAX  CONSEQUENCES  TO YOU HOLDING OR
EXERCISING YOUR ANTEON OPTIONS WILL DEPEND ON YOUR SPECIFIC SITUATION.  YOU ARE
STRONGLY  ENCOURAGED  TO  CONTACT  YOUR  OWN TAX  ADVISOR  TO  OBTAIN  SPECIFIC
INFORMATION REGARDING THE TAX CONSEQUENCES TO YOU OF HOLDING OR EXERCISING YOUR
ANTEON OPTIONS.

         ISO    optionholders    are   also   reminded   of   their   reporting
responsibilities under their Stock Option Grant Agreement. You are obligated to
notify  Anteon in writing  of a  "disqualifying  disposition"  of any shares of
common  stock  acquired  through  the  exercise  of an  ISO.  A  "disqualifying
disposition"  is the sale of shares acquired  through  exercise of an incentive
stock  option  within  two  years of the grant  date or within  one year of the
purchase date.


C.       EXERCISING STOCK OPTIONS BEFORE THE MERGER

         If you would like to exercise any of your vested  outstanding  ISOs or
nonqualified  vested Anteon  Options prior to the effective time of the Merger,
you may do so by following the procedure described in Section D of this letter.
However,  the FICA tax  savings  discussed  in Section B of this  letter do not
apply to nonqualified stock options.


D.       EXERCISING VESTED INCENTIVE STOCK
         OPTIONS AND NONQUALIFIED STOCK OPTIONS

         If you would like to exercise any of your  outstanding  vested  Anteon
Options,  whether they are ISOs or  nonqualified  stock  options,  prior to the
effective  time of the Merger,  you may do so by completing  and  submitting to
Fidelity a Notice of Exercise and paying the  exercise  price for the shares of
Anteon  common  stock you are  purchasing  no later than four days prior to the
effective date of the Merger.  At this time the effective date of the Merger is
not known.  Anteon will endeavor to provide  optionholders  sufficient  advance
notice  of the  effective  date of the  Merger  in  order to give  holders  the
opportunity to exercise their Anteon Options if they choose,  but Anteon cannot
assure that ample notice will be provided.  At this time, we do not believe the
Merger will occur until after the Special Meeting of Stockholders scheduled for
March 3, 2006.

         To    exercise    your    options    you    may    go    on-line    to
www.netbenefits.fidelity.com,  or if you are subject to pre-clearance,  you may
call Fidelity at  800-544-9354.  A Notice of Exercise is not effective until it
and any required cash payments are received by Fidelity.

         Please note that if you are prohibited from effecting  transactions in
Anteon  securities  during the current  trading  blackout period under Anteon's
Securities  Trading Policy  (Policy Number 1507),  you may exercise your Anteon
Options,  but you may not sell your  shares of Anteon  common  stock or utilize
Fidelity  for  "cashless"  exercises.  Anteon  does not  anticipate  ending the
current blackout period prior to the closing of the Merger.

         THIS LETTER IS INFORMATIONAL  ONLY, DOES NOT CONSTITUTE TAX ADVICE AND
IS NOT INTENDED TO  REPRESENT A  DISCUSSION  OF THE FULL SCOPE OF TAX RULES AND
REGULATIONS TO BE CONSIDERED BY EACH OPTIONHOLDER.  TAX MATTERS ARE COMPLEX AND
EACH OPTION HOLDER SHOULD SEEK THE ADVICE OF A QUALIFIED  TAX  PROFESSIONAL  TO
OBTAIN A FULL AND COMPLETE  UNDERSTANDING  OF ALL THE  SPECIFIC  CONSIDERATIONS
APPLICABLE TO YOUR INDIVIDUAL TAX SITUATION.

         If you have any questions regarding your Anteon Options please contact
Fidelity at 800-544-9354  or Heather Sheu at (703) 246-0749.  If you would like
to obtain a report regarding the status of your Anteon Options,  please contact
Fidelity at 800-544-9354.
