         Anteon  International   Corporation,   a  Delaware  corporation  (the
"COMPANY"), is amending the Registration Statement on Form 8-A relating to its
Preferred  Stock  Purchase  Rights  (the  "PURCHASE  RIGHTS")  filed  with the
Securities and Exchange Commission on March 4, 2002 (the "FORM 8-A").

ITEM 1.  DESCRIPTION OF REGISTRANT'S SECURITIES TO BE REGISTERED.
- -----------------------------------------------------------------

         Item 1 of the Form 8-A is hereby amended by adding the following:

         On December 13, 2005, the Company  entered into an Agreement and Plan
of Merger,  dated  December  13, 2005 (as the same may be amended from time to
time, the "MERGER  AGREEMENT"),  with General Dynamics  Corporation  ("GENERAL
DYNAMICS") and Avenger Acquisition  Corporation,  a wholly-owned subsidiary of
General Dynamics ("MERGER SUB"),  pursuant to which Merger Sub will merge with
and into the Company and the Company will become a wholly-owned  subsidiary of
General Dynamics. In connection therewith,  the Company entered into Amendment
No.  1,  dated  as of  December  13,  2005  (the  "AMENDMENT")  to the  Rights
Agreement,  dated as of March 15, 2002 (the "RIGHTS  AGREEMENT"),  between the
Company  and  American  Stock  Transfer  & Trust  Company,  as  rights  agent.
Capitalized  terms used and not  otherwise  defined  herein have the  meanings
ascribed to them in the Rights Agreement.

         The  Amendment  amends the Rights  Agreement so that neither  General
Dynamics,  Merger Sub nor any of their  respective  affiliates  or  associates
shall be deemed to be an Acquiring Person, no Section 11(a)(ii) Event, Section
13(a) Event,  Separation  Date,  Shares  Acquisition  Date or Triggering Event
shall  occur or be  deemed  to occur  and no  holder  of any  Rights  shall be
entitled to exercise such Rights pursuant to any of Sections 3(a), 7(a), 11(a)
or 13 of the Rights Agreement by reason of the approval, execution,  delivery,
public announcement or performance of the Merger Agreement or the consummation
of the transactions  contemplated thereby. The Amendment further provides that
the Rights will expire  immediately prior to the Effective Time (as defined in
the Merger Agreement).

         The  foregoing  description  of the  Amendment  is  qualified  in its
entirety by reference to the Amendment,  which is filed as an exhibit  hereto,
and is expressly incorporated herein by reference.



                                                                             3
