THIS  FILING  CONSISTS  OF AN FAQ REGARDING THE PROPOSED MERGER TRANSACTION.




                             ESSEX COMPANY PRIVATE


            EMPLOYEE FREQUENTLY ASKED QUESTIONS ABOUT THE ACQUISITION

Q:       WHY ARE WE DOING THIS NOW?
A: Northrop Grumman  presented an offer to our board of directors that our board
determined was in the best interests of our shareholders in maximizing long-term
shareholder value and would be advantageous to our customers.  A special vote of
our  shareholders  will be  conducted  in the near  future  in  accordance  with
procedures and requirements set by the Securities and Exchange Commission.

                    QUESTIONS ABOUT THE PROPOSED ACQUISITION:

Q:       HOW WILL THIS TRANSACTION WORK?
A: All of  Essex's  stock will be  acquired  at $24.00 per share in cash after a
shareholders vote to accept that price and after the other closing conditions to
the transaction are satisfied.

Q:       WHEN WILL THIS BE COMPLETED?
A: We expect that the  transaction  will be completed  during the first calendar
quarter of 2007.  Before it can be completed,  proxy materials must be submitted
to the  Securities  and Exchange  Commission  and the  transaction  must receive
anti-trust (Hart-ScottRodino) and certain other regulatory clearance and it must
be approved by the shareholders of Essex Corporation.

Q:       WHY DOES IT TAKE SO LONG?
A:       The shareholder vote must be conducted in accordance with established
procedures and timelines, and the governmental reviews
must be completed before the transaction may be completed.

Q:       HOW DOES ESSEX FIT INTO NORTHROP GRUMMAN? DOES ESSEX CORPORATION GO
AWAY WHEN THIS IS DONE?
A: Under the proposed acquisition, Essex will be a business unit operated within
Northrop Grumman Mission Systems sector. Once the acquisition is completed,  the
Essex stock will no longer be publicly traded but will be converted into cash at
$24.00 per share. However, we expect to continue to operate as a subsidiary with
the Mission Systems sector, and we will continue to use the Essex name following
the acquisition.

Q:       WHAT IS LEN MOODISPAW'S NEW ROLE?
A:       Len will run Essex as head of a business unit within Northrop Grumman's
Mission Systems sector.

Q:       DID OTHER COMPANIES BID ON ESSEX?
A:       Information about the background of the merger will be in the proxy
materials we file with the SEC.

Q:       HOW WAS THE PRICE DETERMINED?  HOW DO WE KNOW IT IS A FAIR PRICE?
A: The price was  determined  through  discussions  between  Essex and  Northrop
Grumman.  The  Board of  Directors  decided  that the  offer  and the  terms and
conditions of the proposed  acquisition  were fair and in the best  interests of
shareholders  and



unanimously  voted to present it to the  shareholders  with a recommendation to
approve the acquisition.

Q:       WHAT VOTE IS REQUIRED BY SHAREHOLDERS TO  APPROVE THE ACQUISITION?
A:       Essex is incorporated in the State of Virginia, which requires a 2/3
vote in favor of the transaction.

Q:       WHAT HAPPENS NEXT?
A:       A few regulatory clearances need to be obtained and the transaction
will be submitted to a shareholder vote.

                        STOCK & OPTION RELATED QUESTIONS:

Q:       WHAT HAPPENS TO MY STOCK AND STOCK OPTIONS?
A: If the  acquisition  is approved by the  shareholders,  then a "closing date"
will be established  shortly  following  shareholder  approval.  On that closing
date,  all issued  stock will be converted  into the right to receive  $24.00 in
cash, and all outstanding options, both vested and unvested,  will be terminated
by cashing them out. Option holders will then be paid the difference between the
offered price ($24 per common stock share) and the exercise price of the option,
less any required  withholding taxes, for each outstanding option for a share of
common stock that you own as of the "closing date".

Q:       WHAT DO I NEED TO DO REGARDING MY STOCK OPTIONS AND/OR STOCK?
A: Once the  acquisition  is approved,  the conversion of your stock and options
will  occur  automatically  if your  shares  are  held by a  broker.  Additional
information will be provided to all shareholders and stock option holders in the
form of a Proxy Statement that will be mailed to them.

Q:       ARE THERE TAX IMPLICATIONS FOR 2006 IF I HAVE ESSEX STOCK OR STOCK
OPTIONS BECAUSE OF THIS TRANSACTION?
A:       Because the proposed acquisition is not expected to be completed until
2007, it should not have a tax impact in 2006.  If
you have specific tax related questions about this transaction, you should
consult with a financial advisor or tax professional.

Q:       IF I HAVE ESSEX STOCK, MAY I TRADE IT BETWEEN NOW AND THE TIME THE
PROPOSED ACQUISITION COMPLETES?
A: So long as we are not in a trading black-out period, and provided that you do
not have  non-public  information  that could  impact the value of Essex  stock,
employees of Essex may trade their Essex stock as they normally would.

Q:       WHEN AND HOW WILL I BE PAID FOR MY ESSEX STOCK AND STOCK OPTIONS?
A: Payment will be made promptly following the closing of the acquisition, which
is expected to occur in the first quarter of 2007. Additional  information about
how and when payment will be made will be provided to all shareholders and stock
option holders in the form of a Proxy Statement that will be mailed to them.




                           BENEFITS RELATED QUESTIONS:

Q:       WHAT HAPPENS TO MY BENEFITS?
A: There is no plan for changes to your Essex benefits during 2007. For one year
after closing your  benefits  will continue to be no less  favorable to you than
either those provided to you now, except that  discretionary  incentive programs
will remain  discretionary  or those  provided to  similarly  situated  Northrop
Grumman employees.  After 2007, some aspects of your benefits may be merged with
the Northrop Grumman benefits program.

Q:       WHAT HAPPENS TO MY TIME OF SERVICE WITH THE ESSEX?  DOES THE "COUNTER"
 GO TO ZERO OR IS MY TIME WITH ESSEX TRANSFERRED OVER?
A:       Your time of service with Essex will be transferred and recognized by
Northrop.

Q:       WHAT HAPPENS TO LEAVE POLICIES AND MY VACATION AND SICK LEAVE BALANCES?
A:       All leave balances will move over intact and accrual and use policies
will continue to be the same throughout 2007.  Some changes may occur following
2007, but you will be informed of any changes in advance.

Q:       WE JUST STARTED OPEN ENROLLMENT, DOES THAT CHANGE NOW?
A:       There is no change to the open enrollment process that we have just
started.

Q:       WHAT HAPPENS TO THE PERFORMANCE AND SALARY REVIEW PROCESS THAT JUST
STARTED?
A:       The performance and salary review process and schedule currently under
way are not changing.

Q:       WHAT HAPPENS TO MY EMPLOYEE STOCK PURCHASE PLAN?
A: Between now and closing, the Essex Employee Stock Purchase Plan will continue
to  operate.  If you  currently  are  enrolled  in the ESPP  and have a  payroll
deduction, it will continue.  Effective immediately,  however, new enrollment in
the ESPP is closed and existing payroll  deductions may not be increased.  Also,
effective  immediately,  no ESPP  purchases  may be made with  checks.  Once the
acquisition is completed, the ESPP will be terminated and the payroll deductions
for it will cease.

Q:       WHAT HAPPENS TO MY 401K?
A: For 2007,  your 401K program will continue and no transfers or rollovers will
be necessary. In the future there may be changes to this program and you will be
provided information at that time. As previously disclosed,  the Windermere 401K
program was scheduled to be terminated as of 12/31/2006.

                             JOB RELATED QUESTIONS:

Q:       WILL EMPLOYEES BE ABLE TO MOVE TO OTHER JOBS WITHIN NORTHROP GRUMMAN
IF THEY WANT TO WHEN THIS IS DONE?
A:       Northrop Grumman maintains an active internal recruitment program and
if the acquisition is approved and Essex becomes part
of Northrop Grumman, these programs and resources will be available to everyone
in Essex.




Q: WHAT HAPPENS TO MY JOB IF I WORK ON OVERHEAD?  WILL EVERYONE HAVE A JOB AFTER
THE  ACQUISITION  IS COMPLETED?  A: We expect  everyone will continue to do what
they are doing now, both direct and overhead  positions.  Ultimately  some roles
and responsibilities may change as we operate as part of Northrop Grumman.  This
will be part of a transition  process that will occur over time. Because this is
a strategic  acquisition  for  Northrop  Grumman,  the  objective  is focused on
leveraging the capabilities and strengths that Essex has established rather than
on cost cutting.

Q:      WHAT IS GOING TO HAPPEN TO THE "EMPLOYEE-ORIENTED CULTURE" OF ESSEX?
A:      Northrop has told us they want the company culture of Essex to continue.

Q:       WHAT HAPPENS TO MY JOB?
A:       Keep doing the great work for which Essex is known.  No one's job is
going away, and it is important that we don't getdistracted from our obligations
 to our customers and our shareholders.

Q:       WHAT HAPPENS TO MY SECURITY CLEARANCE?  DO I HAVE TO DO ANYTHING?
A:       All security clearances and security interests held by Essex will be
transferred as part of the acquisition.  You will not be required to do anything
with your security clearance because of the proposed acquisition.

Q:       WHAT HAPPENS TO ESSEX (OR WINDERMERE OR AOA) CONTRACTS?
A:  All  of  our  contracts,  outstanding  proposals,  teaming  agreements,  and
non-disclosure  agreements  will remain in place and continue in force under the
Essex subsidiary that will be created within Northrop Grumman.

Q: IS ESSEX  GOING TO BE SPLIT UP OR WILL IT  CONTINUED  TO  OPERATE AS A WHOLE,
INCLUDING  THE RECENT  ACQUISITION  OF AOA?  A: There is no plan for Essex to be
split up or  broken  apart  as a  result  of the  acquisition.  Our most  recent
acquisition,  AOA, is an important  part of Essex and there is currently no plan
to move it to a different group within Northrop or sell it.

Q:       IS THERE A PLAN TO CONSOLIDATE FACILITIES WITH OTHER NORTHROP GRUMMAN
FACILITIES?
A:  There is no plan to  consolidate  or  change  facilities  as a result of the
acquisition,  but we will be looking  for ways to reduce  costs and  enhance the
integration of Essex with Northrop Grumman.  As new requirements for space occur
after  the  acquisition  and as  leases  expire,  we expect to look for the best
options for our employees and our customers in making facility decisions.

Q:       I AM A MANAGER, WHAT SHOULD I TELL MY EMPLOYEES IF THEY HAVE QUESTIONS?
A:       If you or your staff have additional questions, you should ask the
General Manager of your sector within Essex.






                           CUSTOMER RELATED QUESTIONS:

Q:       DOES MY CUSTOMER KNOW ABOUT THIS?  WHAT DO I TELL MY CUSTOMER
IF THEY ASK ME QUESTIONS?
A: A small number of our largest  customers have been  informed,  and we will be
reaching out to all of them as quickly as possible.  Our customers should expect
to  continue  to receive  the same great  level of support  from Essex after the
acquisition  as they receive  today.  If your  customer has specific  questions,
please  have them  contact  the Essex  General  Manager of your  sector for more
information.

Q:       WHAT IF MY CUSTOMER DOESN'T LIKE THE ACQUISITION - WHAT DO I SAY?
A: First if you believe there is a customer concern like this, tell your manager
and/or  your  General  Manager.  Second,  if you learn  that your  customer  has
concerns about the acquisition, then get your manager involved.

                                MORE QUESTIONS?:

Q:       WHAT IF I HAVE MORE QUESTIONS?  WHOM DO I ASK?
A:       If you have additional questions, you should ask your manager and/or
the General Manager of your sector within Essex.
