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

TO ALL VP'S AND ABOVE:

The following is a summary of the presentation that took place when General
Dynamics' Chairman and CEO, Nick Chabraja, visited Anteon on December 13th.
Again, apologies for the technical difficulties experienced with the telephone
dial-in service and for not getting this out sooner, as promised.

On Tuesday, December 13th Joe Kampf and Dan Johnson, along with General
Dynamics' Chairman and CEO Nick Chabraja, EVP of Information Systems &
Technology Gerry Demuro, and President of Network Systems Mike Chandler, met
with Anteon's Vice Presidents and above in the Fairfax office to discuss the
acquisition of Anteon. Unfortunately, those who were on the phone via
teleconference were cut off during the conversation due to technical
difficulties. The following is a brief summary of the discussion.

Joe and Nick Chabraja discussed how they met years ago and from time to time,
have discussed a possible combination...but the timing never seemed right for
either company. Things got moving in late October 2005 and it really came
together over the last 5-6 business days, prior to agreeing to a deal on
December 12th. It is an all cash deal, expected to close by the end of the
second quarter of 2006. Both Joe and Nick agreed it provides strong value to all
shareholders and makes a lot of sense from both a strategic and marketplace
perspective.

Assuming the transaction closes as planned, Anteon will operate as a wholly
owned subsidiary, and will be a part of General Dynamic's $9 billion Information
Systems and Technology sector. This sector accounts for more than 40% of General
Dynamics' revenues today.

From a strategic perspective, this is a very good transaction for both
companies. It gives General Dynamics a huge footprint in the $150 billion
Federal IT marketplace. From General Dynamics' perspective, Anteon's mission
systems/war fighter support footprint, IT solutions skills, and strong
engineering capabilities makes Anteon the most admired company in the federal
services marketplace. General Dynamics feels Anteon's business model generates
industry leading growth rates and General Dynamics would like to find ways of
infusing Anteon's business development/GWAC/task order successes into other
parts of GD.


General Dynamics' legacy of growing into a major player in the Federal IT market
began with the acquisition of Lucent Advanced Technology Systems in 1997, and
continued with other transactions involving GTE, Veridian, DSR, FC Business
Systems, and others... but these companies didn't bring the mission systems
footprint and DoD presence that Anteon has.

Timing had a lot to do with the acquisition, as both Anteon and General Dynamics
had to allow their strategies to mature before considering this important step
in the development of a federal services tier one move. Needless to say, the
board of each company agreed that the timing, strategy, and valuation were right
to do a deal now.


The following represents the material Q/A that took place at the end of the
presentation. Of course, there are many questions that we will not be able to
answer until after the transaction closes and we develop a longer term view of
our joint operating plan:

Q: What will happen to the Long-Term Incentive Program that was announced in
November?
A: The program is on hold at this time. We'll be working with GD to
understand their equity incentive programs and how best to apply them to Anteon.

Q: How will organizational conflicts of interest issues be addressed?
A: There may be some, but we do not anticipate the issue to be significant.
Please contact Bill Gunst, Robert Toth, Arleigh Closser and Johann Dretchen if
you have any customer issues related to OCI.

Q: Will the senior management team remain in place?
A: No organizational/integration plans have been developed at this time. Anteon
will continue to operate independently through the transaction closing date.
Subsequently, we will operate as a wholly-owned subsidiary while our management
team works with GD on the appropriate way to go to market and continue to grow
the business. We expect minimal disruption to our organizational structure and
we will certainly keep all of our employees informed as our strategy evolves
over time. Meantime, it's business as usual.

Q: What changes in benefits can employees expect?
A: There are no anticipated changes in benefits for 2006. Beyond 2006, we expect
to receive benefits at least equivalent to our GD counterparts, and generally
comparable to our current plans. GD's current benefits and compensation
philosophy is very similar to ours. Each company recognizes that we are in a
people business and that our employees are our most valuable asset. Therefore,
providing appropriate benefits, motivating the workforce, providing incentives
for key people, and producing high levels of customer satisfaction will always
be basic tenants of our business model.

We will keep you informed as we proceed down this path that we believe is a NEW
BEGINNING for Anteon.

Again, please refrain from discussing the acquisition with the media and others
outside Anteon. Please reference the last NewsFlash and recent emails from the
Office of General Counsel regarding our communications policy.

Thank you.

Dan Johnson
Chief Operating Officer
