Item 9.  Undertakings.

(a)      The undersigned Registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this Registration Statement:

                  (i)      To include any prospectus required by Section
10(a)(3) of the Securities Act;

                  (ii) To reflect in the  prospectus any facts or events arising
after the  effective  date of this  Registration  Statement  (or the most recent
post-effective  amendment  thereof)  which,  individually  or in the  aggregate,
represent a fundamental change in the information set forth in this Registration
Statement;

                  (iii) To include any material  information with respect to the
plan of distribution not previously disclosed in this Registration  Statement or
any material change to such information in this Registration Statement;

         Provided,  however,  that paragraphs (a)(1)(i) and (a)(1)(ii) shall not
apply if the information  required to be included in a post-effective  amendment
by those  paragraphs is contained in periodic  reports  filed by the  Registrant
pursuant to Section 13 or 15(d) of the  Exchange  Act that are  incorporated  by
reference in this Registration Statement.

         (2) That,  for the  purpose  of  determining  any  liability  under the
Securities Act, each such  post-effective  amendment shall be deemed to be a new
registration  statement  relating to the  securities  offered  therein,  and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

                                      II-2

<PAGE>

         (3) To remove from registration by means of a post-effective  amendment
any of the securities being registered which remain unsold at the termination of
the offering.

(b)  The  undersigned   Registrant  hereby  undertakes  that,  for  purposes  of
determining  any  liability  under  the  Securities  Act,  each  filing  of  the
Registrant's  annual  report  pursuant to Section 13(a) or 15(d) of the Exchange
Act that is  incorporated by reference in this  Registration  Statement shall be
deemed to be a new  registration  statement  relating to the securities  offered
therein,  and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

(c) Insofar as indemnification  for liabilities arising under the Securities Act
may  be  permitted  to  directors,  officers  and  controlling  persons  of  the
Registrant pursuant to the foregoing  provisions,  or otherwise,  the Registrant
has been advised that in the opinion of the Securities  and Exchange  Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore,  unenforceable. In the event that a claim for indemnification
against such  liabilities  (other than the payment by the Registrant of expenses
incurred or paid by a director,  officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director,  officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as  expressed  in the  Securities  Act and will be  governed by the final
adjudication of such issue.

                                ESSEX CORPORATION
                 1999 STOCK OPTION AND APPRECIATION RIGHTS PLAN

                                    ARTICLE I
                            ESTABLISHMENT AND PURPOSE

         Section 1.1. Essex Corporation (the "Company"), a Virginia corporation,
hereby  establishes a stock option and appreciation  rights plan to be named the
Essex  Corporation  1999 Stock  Option and  Appreciation  Rights Plan (the "1999
Plan").

         Section 1.2. The purpose of this 1999 Plan is to induce persons who are
officers,  directors,  employees  and  consultants  of the Company or any of its
subsidiaries  who are in a position to  contribute  materially  to the Company's
prosperity  to remain with the  Company,  to offer said persons  incentives  and
rewards in recognition of their contributions to the Company's progress,  and to
encourage said persons to continue to promote the best interests of the Company.
This 1999 Plan  provides  for the grant of options to purchase  shares of common
stock of the  Company,  par value  $.10 per share  (the  "Common  Stock")  which
qualify as incentive  stock options  ("Incentive  Options") under Section 422 of
the Internal  Revenue Code of 1986, as amended (the "Code"),  to persons who are
employees, as well as options which do not so qualify ("Non-Qualified  Options")
to be issued to persons or  consultants,  including those who are not employees.
This 1999 Plan also provides for grants of stock appreciation rights ("SARs") in
connection with the grant of options under this 1999 Plan. Incentive Options and
Non-Qualified  Options  may  be  collectively  referred  to  hereinafter  as the
"Options" as the context may require.

         Section  1.3. All options and other  rights  previously  granted by the
Company under any other plan previously adopted by the Company shall continue to
be governed by such plan.  All Options  granted  hereunder  on or after the date
that this 1999 Plan has been  approved  and  adopted by the  Company's  board of
directors  (the  "Board  of  Directors")  shall be  governed  by the  terms  and
conditions  of this  1999 Plan  unless  the  terms of such  Option  specifically
indicate that it is not to be so governed.

                                   ARTICLE II
                                 ADMINISTRATION

         Section 2.1. All  determinations  under this 1999 Plan  concerning  the
selection  of persons  eligible to receive  awards under this 1999 Plan and with
respect to the timing, pricing and amount of an award under this 1999 Plan shall
be made by the  administrator  (the  "Administrator")  of this  1999  Plan.  The
Administrator  shall  be  either:  (a)  the  Board  of  Directors  or (b) in the
discretion  of the Board of Directors by a committee  (the  "Committee")  of the
Board of  Directors of two or more  members of the Board of  Directors,  each of
whom is a "Non-Employee director" as such term is defined by Rule 16b-3 (as such
rule may be  amended  from time to time,  "Rule  16b-3")  under  the  Securities
Exchange Act of 1934, as amended (the "Exchange  Act"). In such case, a majority
of the total number of members of the Committee shall be necessary to constitute
a quorum;  and (i) the  affirmative  act of a majority of the members present at
any meeting at which a quorum is present,  or (ii) the  approval in writing by a
majority of the members of the Committee shall be necessary to constitute action
by the Committee.

         With  respect to persons  subject  to Section 16 of the  Exchange  Act,
transactions  under this 1999 Plan are  intended to comply  with all  applicable
conditions of Rule 16b-3 or its successors under the Exchange Act. To the extent
that any provision of this 1999 Plan or action by the Administrator  fails to so
comply,  it shall be deemed to be null and void, to the extent  permitted by law
and deemed advisable by the Administrator.

         Section 2.2.  The  provisions  of this 1999 Plan  relating to Incentive
Options are  intended to comply in every  respect  with  Section 422 of the Code
("Section 422") and the regulations  promulgated  thereunder.  In the event that
any future statute or regulation  shall modify Section 422, this 1999 Plan shall
be deemed to  incorporate  by  reference  such  modification.  Any stock  option
agreement  relating to the grant of any Incentive  Option  pursuant to this 1999
Plan, which option is outstanding and unexercised at the time that any modifying
statute or regulation becomes effective,  shall also be deemed to incorporate by
reference such modification, and no notice of such modification need be given to
the Optionee (as hereinafter defined). Any stock option agreement relating to an
Incentive  Option shall provide that the Optionee (as hereinafter  defined) hold
the stock received upon exercise of such  Incentive  Option for a minimum of two

<PAGE>

years from the date of grant of the Incentive  Option and one year from the date
of exercise of such Incentive Option,  absent the written  approval,  consent or
waiver of the Administrator.

         Section  2.3.  If any  provision  of this  1999 Plan is  determined  to
disqualify the shares of Common Stock  purchasable upon exercise of an Incentive
Option  granted under this 1999 Plan from the special tax treatment  provided by
Section 422,  such  provision  shall be deemed to  incorporate  by reference the
modification  required  to  qualify  such  shares of  Common  Stock for said tax
treatment.

         Section 2.4. The Company  shall grant  Options  under this 1999 Plan in
accordance  with  determinations  made  by  the  Administrator  pursuant  to the
provisions  of this 1999 Plan.  All Options  granted  pursuant to this 1999 Plan
shall be clearly identified as Incentive Options or Non-Qualified  Options.  The
Administrator may from time to time adopt (and thereafter amend or rescind) such
rules and  regulations  for  carrying out this 1999 Plan and take such action in
the  administration  of this 1999 Plan,  not  inconsistent  with the  provisions
hereof,  as it shall deem  proper.  The Board of  Directors  or,  subject to the
supervision  of the Board of Directors,  the  Committee,  as the  Administrator,
shall have plenary  discretion,  subject to the express  provisions of this 1999
Plan, to determine which officers, directors, employees and consultants shall be
granted Options,  the number of shares subject to each Option, the time or times
when an Option may be exercised  (whether in whole or in installments),  whether
Rights under  Section 7.6 hereof shall be granted,  the terms and  provisions of
the respective option  agreements (which need not be identical),  including such
terms  and  provisions  which  may be  amended  from  time to time as  shall  be
required, in the judgment of the Administrator,  to conform to any change in any
law or regulation applicable hereto, and to make all other determinations deemed
necessary  or  advisable  for  the   administration   of  this  1999  Plan.  The
interpretation  and  construction  of any  provision  of this  1999  Plan by the
Administrator  (unless otherwise  determined by the Board of Directors) shall be
final, conclusive and binding upon all persons.

         Section  2.5.  No member of the  Administrator  shall be liable for any
action or  determination  made in good faith with respect to  administration  of
this 1999 Plan or the Options granted  hereunder.  A member of the Administrator
shall be indemnified by the Company,  pursuant to the Company's bylaws,  for any
expenses,  judgments  or other  costs  incurred  as a result of a lawsuit  filed
against such member claiming any rights or remedies arising out of such member's
participation in the administration of this 1999 Plan.

                                   ARTICLE III
                      TOTAL NUMBER OF SHARES TO BE OPTIONED

         Section  3.1.  There shall be reserved  for  issuance or transfer  upon
exercise  of  Options  to be  granted  from time to time under this 1999 Plan an
aggregate  of  300,000  shares  of  Common  Stock  of the  Company  (subject  to
adjustment as provided in Article VIII hereof).  The shares issued upon exercise
of any  Options  granted  under  this 1999  Plan may be  shares of Common  Stock
previously  issued and  reacquired by the Company at any time or authorized  but
unissued shares of Common Stock, as the Board of Directors from time to time may
determine.

         Section 3.2. In the event that any Options  outstanding under this 1999
Plan for any reason expire or are  terminated  without  having been exercised in
full or shares of Common Stock subject to Options are surrendered in whole or in
part pursuant to Rights  granted under Section 7.6 hereof  (except to the extent
that  shares of Common  Stock are  issued as payment to the holder of the Option
upon such  surrender)  the  unpurchased  shares of Common Stock  subject to such
Option and any such  surrendered  shares of Common  Stock may again be available
for transfer under this 1999 Plan.

         Section 3.3. No Options shall be granted  pursuant to this 1999 Plan to
any  Optionee  after  the tenth  anniversary  of the date that this 1999 Plan is
adopted by the Board of Directors.

                                   ARTICLE IV
                                   ELIGIBILITY

         Section 4.1. Non-Qualified Options may be granted pursuant to this 1999
Plan to officers, directors, employees and consultants of the Company (or any of
its subsidiaries)  selected by the  Administrator,  and Incentive Options may be
granted  pursuant to this 1999 Plan only to  employees  (including  officers and
directors who are also  employees)  of the Company (or any of its  subsidiaries)
selected by the  Administrator.  Persons granted  Options  pursuant

                                       ii

<PAGE>

to this  1999  Plan are  referred  to herein as  "Optionees."  For  purposes  of
determining  who is an  employee  with  respect  to  eligibility  for  Incentive
Options,  Section 422 shall govern. The Administrator may determine (in its sole
discretion)  that any  person  who would  otherwise  be  eligible  to be granted
Options shall,  nonetheless,  be ineligible to receive any award under this 1999
Plan.
         Section 4.2. The Administrator  will (in its discretion)  determine the
persons  to be  granted  Options,  the time or times at which  Options  shall be
granted,  the number of shares of Common Stock subject to each Option, the terms
of a vesting or  forfeiture  schedule,  if any, the type of Option  issued,  the
period during which such Options may be  exercised,  the manner in which Options
may be exercised and all other terms and  conditions  of the Options;  provided,
however,  no Option will be granted which has terms or  conditions  inconsistent
with those stated in Articles V and VI hereof.  Relevant  factors in making such
determinations  may include the value of the services rendered by the respective
Optionee,  his or her present and potential  contributions  to the Company,  and
such other factors  which are deemed  relevant in  accomplishing  the purpose of
this 1999 Plan.

                                    ARTICLE V
                         TERMS AND CONDITIONS OF OPTIONS

         Section  5.1.  Each  Option  granted  under  this  1999  Plan  shall be
evidenced  by a stock  option  certificate  and  agreement  (the  "Stock  Option
Certificate and  Agreement") in a form consistent with this 1999 Plan,  provided
that the following terms and conditions shall apply:

         (a) The price at which each share of Common Stock  covered by an Option
may be  purchased  shall  be set  forth  in the  Stock  Option  Certificate  and
Agreement and shall be determined by the Administrator, provided that the option
price for any Incentive Option shall not be less than the "fair market value" of
the shares of Common Stock at the time of grant  determined in  accordance  with
Section 5.1(b) below.  Notwithstanding the foregoing,  if an Incentive Option to
purchase  shares of Common  Stock is  granted  pursuant  to this 1999 Plan to an
Optionee who, on the date of the grant,  directly or  indirectly  owns more than
ten percent  (10%) of the voting  power of all  classes of capital  stock of the
Company (or its parent or subsidiary),  not including the shares of Common Stock
obtainable  upon  exercise of the Option,  the  minimum  exercise  price of such
Option shall be not less than one hundred ten percent (110%) of the "fair market
value"  of the  shares  of  Common  Stock  on the date of  grant  determined  in
accordance with Section 5.1(b) below.

         (b) The "fair market value" shall be  determined by the  Administrator,
which  determination  shall  be  binding  upon  the  Company  and its  officers,
directors, employees and consultants. The determination of the fair market value
shall be based upon the  following:  (i) if the  shares of Common  Stock are not
listed and traded upon a recognized  securities  exchange and there is no report
of stock  prices  with  respect to the  shares of Common  Stock  published  by a
recognized  stock quotation  service,  on the basis of the recent  purchases and
sales of the shares of Common Stock in arms-length transactions;  or (ii) if the
shares  of  Common  Stock  are not then  listed  and  traded  upon a  recognized
securities  exchange or quoted on the NASDAQ Stock Market, and there are reports
of stock prices by a recognized  quotation  service,  upon the basis of the last
reported  sale or  transaction  price  of such  stock  on the  date of  grant as
reported by a recognized  quotation  service,  or, if there is no last  reported
sale or  transaction  price on that day,  then upon the basis of the mean of the
last reported closing bid and closing asked prices for such stock on that day or
on the date nearest  preceding  that day; or (iii) if the shares of Common Stock
shall then be listed and traded upon a recognized  securities exchange or quoted
on the  NASDAQ  Stock  Market,  upon  the  basis of the  last  reported  sale or
transaction price at which shares of Common Stock were traded on such recognized
securities  exchange on the date of grant or, if the shares of Common Stock were
not traded on such date, upon the basis of the last reported sale or transaction
price on the date nearest  preceding  that date.  The  Administrator  shall also
consider such other  factors  relating to the fair market value of the shares of
Common Stock as it shall deem appropriate.

         (c) For the purpose of  determining  whether an Optionee owns more than
ten percent (10%) of the voting power of all classes of stock of the Company, an
Optionee  is  considered  to own  those  shares  which  are  owned  directly  or
indirectly  through  brothers  and sisters  (including  half-blooded  siblings),
spouse,  ancestors and lineal descendants;  and proportionately as a shareholder
of a corporation, a partner of a partnership, and/or a beneficiary of a trust or
an estate that owns shares of the Company.

         (d)   Notwithstanding  any  other  provision  of  this  1999  Plan,  in
accordance with the provisions of Section 422(d) of the Code, to the extent that
the aggregate  fair market value  (determined at the time the Option is

                                      iii

<PAGE>

granted)  of the shares of Common  Stock of the  Company  with  respect to which
Incentive Options (without  reference to this provision) are exercisable for the
first time by any individual in any calendar year under any and all stock option
plans of the  Company,  its  subsidiary  corporations  and its  parent  (if any)
exceeds $100,000, such Options shall be treated as Non-Qualified Options.

         (e) An Optionee may, in the Administrator's discretion, be granted more
than one Incentive  Option or  Non-Qualified  Option during the duration of this
1999  Plan,  and may be  issued  a  combination  of  Non-Qualified  Options  and
Incentive  Options;  provided,  however,  that non-employees are not eligible to
receive Incentive Options.

         (f) The duration of any Option and any Right  related  thereto shall be
within the sole discretion of the  Administrator;  provided,  however,  that any
Incentive  Option  granted to a ten  percent  (10%) or less  stockholder  or any
Non-Qualified  Option shall, by its terms,  be exercised  within ten years after
the date the Option is granted  and any  Incentive  Option  granted to a greater
than ten percent (10%) stockholder shall, by its terms, be exercised within five
years after the date the Option is granted.

         (g) An Option and any Right related  thereto shall not be  transferable
by the Optionee other than by will, or by the laws of descent and  distribution.
An Option may be exercised during the Optionee's lifetime only by the Optionee.

         (h) The  Administrator  may impose such other or further  conditions on
any transaction under the 1999 Plan, including without limitation,  the grant or
award of any Option or the exercise or other disposition  thereof, as it, in its
discretion,  may deem necessary or advisable in order to exempt the  transaction
from Section 16(b) of the Exchange Act,  including without  limitation  thereto,
the approval or  ratification  of the transaction by shareholders or a six-month
restriction  on  disposition  of the Option or the Common  Stock  issuable  upon
exercise thereof.

                                   ARTICLE VI
                        EMPLOYMENT OR SERVICE OF OPTIONEE

         Section 6.1. If the  employment or service of an Optionee is terminated
for cause,  the option rights of such Optionee,  both accrued and future,  under
any  then   outstanding   Non-Qualified  or  Incentive  Option  shall  terminate
immediately.  "Cause"  shall mean  incompetence  in the  performance  of duties,
disloyalty, dishonesty, theft, embezzlement, unauthorized disclosure of patents,
processes  or trade  secrets of the  Company,  individually  or as an  employee,
partner, associate,  officer or director of any organization.  The determination
of the  existence  and the proof of "cause"  shall be made by the  Administrator
and, subject to the review of any determination made by the Administrator,  such
determination shall be binding on the Optionee and the Company.

         Section 6.2. If the employment or service of the Optionee is terminated
by either the  Optionee  or the  Company  for any  reason  other than for cause,
death, retirement or for disability, as defined in Section 22(e)(3) of the Code,
the option rights of such Optionee under any then  outstanding  Incentive Option
shall,  subject to the provisions of Section  5.1(h)  hereof,  be exercisable by
such Optionee at any time prior to the  expiration of the Option or within three
months after the date of such termination,  whichever period of time is shorter,
but only to the extent of the accrued  right to exercise  the Option at the date
of such termination.

         Section  6.3.  In the case of an  Optionee  who  becomes  disabled,  as
defined by Section  22(e)(3)  of the Code,  the option  rights of such  Optionee
under any then outstanding  Incentive Option shall, subject to the provisions of
Section 5.1(h) hereof,  be exercisable by such Optionee at any time prior to the
expiration  of the Option or within one year  after the date of  termination  of
employment or service due to  disability,  whichever  period of time is shorter,
but only to the extent of the accrued  right to exercise  the Option at the date
of such termination.

         Section  6.4.  In the event of the  death of an  Optionee,  the  option
rights of such Optionee  under any then  outstanding  Incentive  Option shall be
exercisable by the person or persons to whom these rights pass by will or by the
laws of descent and  distribution,  at any time prior to the  expiration  of the
Option or within three years after the date of death,  whichever  period of time
is shorter,  but only to the extent of the accrued  right to exercise the Option
at the date of death.  If a person or estate  acquires  the right to exercise an
Incentive  Option by bequest  or  inheritance,  the  Administrator  may  require
reasonable  evidence as to the  ownership of such  Option,  and may require such
consents  and  releases  of taxing  authorities  as the  Administrator  may deem
advisable.

                                       iv

<PAGE>

         Section  6.5. If an Optionee to whom an Option has been  granted  under
this 1999 Plan retires from his employment or service with the Company or any of
the  Subsidiaries  under a  retirement  plan or  policy of the  Company  and its
Subsidiaries  or at his or her  normal  retirement  date  or  earlier  with  the
approval  or consent of the  Company or such  Subsidiary,  or as a result of the
Disability  as  defined in  Section  22(e)(3)  of the Code,  such  Option  shall
continue  to be  exercisable  in whole or in part,  to the extent not  therefore
exercised,  by the Optionee to whom granted in the manner set forth in this 1999
Plan, at any time within the remaining term of such Option.

         Section 6.6. The  Administrator  may also provide that an employee must
be  continuously  employed  by the  Company  for  such  period  of  time  as the
Administrator,  in its discretion,  deems advisable before the right to exercise
any portion of an Option granted to such employee will accrue,  and may also set
such other  targets,  restrictions  or other terms relating to the employment of
the Optionee which targets, restrictions, or terms must be fulfilled or complied
with,  as the case may be,  prior to the  exercise  of any  portion of an Option
granted to any employee.

         Section   6.7.   Except  in  the  event  of   termination   for  cause,
Non-Qualified Options shall be exercisable during such term as determined at the
time of grant by the Administrator.

         Section 6.8. Options granted under this 1999 Plan shall not be affected
by any change of duties or position,  so long as the  Optionee  continues in the
service of the Company.

         Section  6.9.  Nothing  contained  in this 1999 Plan,  or in any Option
granted  pursuant to this 1999 Plan,  shall  confer upon any  Optionee any right
with  respect  to  continuance  of  employment  or service  by the  Company  nor
interfere in any way with the right of the Company to terminate  the  Optionee's
employment or service or change the Optionee's compensation at any time.

                                   ARTICLE VII
                               PURCHASE OF SHARES

         Section 7.1. Except as provided in this Article VII, an Option shall be
exercised by tender to the Company of the full  exercise  price of the shares of
Common Stock with respect to which the Option is exercised and written notice of
the exercise.  The right to purchase  shares of Common Stock shall be cumulative
so that, once the right to purchase any shares of Common Stock has accrued, such
shares or any part  thereof may be purchased  at any time  thereafter  until the
expiration or termination of the Option.  A partial  exercise of an Option shall
not affect the right of the  Optionee to exercise  the Option from time to time,
in  accordance  with this 1999  Plan,  as to the  remaining  number of shares of
Common Stock subject to the Option. The purchase price of the shares shall be in
United   States   dollars,   payable  in  cash  or  by  certified   bank  check.
Notwithstanding  the  foregoing,  in lieu of cash,  an  Optionee  may,  with the
approval of the  Administrator,  exercise  his or her Option by tendering to the
Company  shares of Common Stock of the Company owned by him or her and having an
aggregate fair market value at least equal to the full exercise price.  The fair
market value of any shares of Common Stock so surrendered shall be determined by
the Administrator in accordance with Section 5.1(b) hereof.

         Section 7.2.  Except as provided in Article VI above, an Option may not
be exercised  unless the holder thereof is an officer,  director,  employee,  or
consultant of the Company at the time of exercise.

         Section  7.3.  No  Optionee,  or  Optionee's  executor,  administrator,
legatee, or distributee or other permitted  transferee,  shall be deemed to be a
holder of any  shares of  Common  Stock  subject  to an Option  for any  purpose
whatsoever  unless and until a stock certificate or certificates for such shares
are issued to such person under the terms of this 1999 Plan. No adjustment shall
be made for dividends (ordinary or extraordinary, whether in cash, securities or
other  property) or  distributions  or other rights for which the record date is
prior to the date such  stock  certificate  is  issued,  except as  provided  in
Article VIII hereof.

         Section 7.4. If: (i) the listing,  registration or qualification of the
Options issued  hereunder,  or of any securities  issuable upon exercise of such
Options (the "Subject  Securities")  upon any  securities  exchange or quotation
system  or under  federal  or state law is  necessary  as a  condition  of or in
connection with the issuance or exercise of the Options,  or (ii) the consent or
approval of any  governmental  regulatory body is necessary as a condition of or
in  connection  with the issuance or exercise of the Options,  the Company shall
not be obligated to deliver the certificates representing the Subject Securities
or to accept or to recognize an Option  exercise  unless and until such listing,

                                       v

<PAGE>

registration,  qualification,  consent or approval  shall have been  effected or
obtained.  The Company  will take  reasonable  action to so list,  register,  or
qualify the Options and the Subject Securities, or effect or obtain such consent
or approval, so as to allow for their issuance.

         Section 7.5. An Optionee may be required to represent to the Company as
a condition of his or her exercise of Options  issued under this 1999 Plan that:
(i) the Subject Securities acquired upon exercise of his or her Option are being
acquired  by him or her for  investment  purposes  only  and not  with a view to
distribution or resale,  unless counsel for the Company is then of the view that
such a representation  is not necessary and is not required under the Securities
Act of 1933, as amended (the "Securities Act"), or any other applicable statute,
law,  regulation or rule;  and (ii) that the Optionee  shall make no exercise or
disposition of an Option or of the Subject  Securities in  contravention  of the
Securities  Act,  the  Exchange  Act or the  rules and  regulations  thereunder.
Optionees may also be required to provide (as a condition  precedent to exercise
of an Option) such  documentation as may be reasonably  requested by the Company
to assure  compliance  with  applicable law and the terms and conditions of this
1999 Plan and the subject Option.

         Section  7.6.  The  Administrator  may,  in its  discretion,  grant  in
connection with any Option, at any time prior to the exercise thereof, the right
(previously defined as an "SAR" or collectively, the "SARs") to surrender all or
part of the Option to the extent that such Option is exercisable  and receive in
exchange an amount  (payable in cash,  shares of Common Stock valued at the then
fair market value, or a combination  thereof as determined by the Administrator)
equal to the difference (the "Spread") between the then fair market value of the
shares of Common  Stock  issuable  upon the  exercise of the Option (or portions
thereof  surrendered)  and the option  price  payable  upon the  exercise of the
Option (or portions thereof surrendered). Such SARs may be included in an Option
only under the following conditions:  (a) the SARs will expire no later than the
expiration of the  underlying  Option;  (b) the SARs may be for no more than one
hundred percent (100%) of the Spread;  (c) the SARs are  transferable  only when
the underlying  Option is transferable  and under the same  conditions;  (d) the
SARs may be  exercised  only  when  the  underlying  Option  is  eligible  to be
exercised;  and (e) the SARs may be exercised  only when the Spread is positive,
i.e.,  when the market  price of the stock  subject to the  Option  exceeds  the
exercise price of the Option.

         Section  7.7. An Option may also be  exercised by tender to the Company
of a written notice of exercise together with advice of the delivery of an order
to a broker to sell part or all of the  shares of Common  Stock  subject to such
exercise  notice  and an  irrevocable  order to such  broker to  deliver  to the
Company (or its transfer agent) sufficient proceeds from the sale of such shares
to pay the exercise  price and any  withholding  taxes.  All  documentation  and
procedures to be followed in connection with such a "cashless exercise" shall be
approved in advance by the Administrator.

                                  ARTICLE VIII
                    CHANGE IN NUMBER OF OUTSTANDING SHARES OF
                    STOCK, ADJUSTMENTS, REORGANIZATIONS, ETC.

         Section 8.1. In the event that the  outstanding  shares of Common Stock
of the Company are hereafter increased or decreased or changed into or exchanged
for a different  number of shares or kind of shares or other  securities  of the
Company  or  of  another  corporation  by  reason  of  reorganization,   merger,
consolidation,  recapitalization,  reclassification, stock split, combination of
shares, or a dividend payable in capital stock,  appropriate adjustment shall be
made by the  Administrator  in the number and kind of shares for the purchase of
which Options may be granted under this 1999 Plan,  including the maximum number
that may be granted to any one person. In addition, the Administrator shall make
appropriate adjustments in the number and kind of shares as to which outstanding
Options, or portions thereof then unexercised,  shall be exercisable, to the end
that the  Optionee's  proportionate  interest  shall be maintained as before the
occurrence  to the  unexercised  portion of the Option and with a  corresponding
adjustment  in the  option  price per  share.  Any such  adjustment  made by the
Administrator shall be conclusive.

         Section  8.2.  The grant of an Option  pursuant to this 1999 Plan shall
not  affect in any way the right or power of the  Company  to make  adjustments,
reclassifications,  reorganizations  or  changes  of  its  capital  or  business
structure or to merge or to  consolidate  or to dissolve,  liquidate or sell, or
transfer all or any part of its business or assets.

         Section 8.3. Upon the  dissolution or  liquidation  of the Company,  or
upon a  reorganization,  merger or  consolidation  of the Company as a result of
which the outstanding  securities of the class then subject to Options hereunder
are changed  into or  exchanged  for cash or property or  securities  not of the
Company's issue, or upon a sale of

                                       vi

<PAGE>

substantially all the property of the Company to an association,  person, party,
corporation,  partnership,  or  control  group  as that  term is  construed  for
purposes  of  the  Exchange  Act,  this  1999  Plan  shall  terminate,  and  all
outstanding  Options  theretofore  granted  hereunder  shall  terminate,  unless
provision  be made in  writing  in  connection  with  such  transaction  for the
continuance of this 1999 Plan and/or for the  assumption of Options  theretofore
granted, or the substitution for such Options of options covering the stock of a
successor  employer  corporation,  or a parent  or a  subsidiary  thereof,  with
appropriate adjustments as to the number and kind of shares and prices, in which
event this 1999 Plan and  options  theretofore  granted  shall  continue  in the
manner  and  under  the terms so  provided.  If this  1999 Plan and  unexercised
Options shall terminate pursuant to the foregoing  sentence,  all persons owning
any unexercised  portions of Options then  outstanding  shall have the right, at
such time prior to the consummation of the transaction  causing such termination
as the Company shall  designate,  to exercise the unexercised  portions of their
Options,  including the portions  thereof which would,  but for this Section 8.3
not yet be exercisable.

                                   ARTICLE IX
                       DURATION, AMENDMENT AND TERMINATION

         Section 9.1. The Board of Directors may at any time terminate this 1999
Plan or make such  amendments  hereto as it shall deem advisable and in the best
interests of the Company,  without action on the part of the stockholders of the
Company unless such approval is required  pursuant to Section 422 of the Code or
the  regulations  thereunder or other federal or state law;  provided,  however,
that  no such  termination  or  amendment  shall,  without  the  consent  of the
individual to whom any Option shall  theretofore  have been granted,  materially
adversely  affect or impair the  rights of such  individual  under such  Option.
Pursuant  to  Section  422(b) of the Code,  no  Incentive  Option may be granted
pursuant  to this  1999 Plan  after  ten  years  from the date this 1999 Plan is
adopted  or the date this  1999  Plan is  approved  by the  stockholders  of the
Company, whichever is earlier.

                                    ARTICLE X
                                  RESTRICTIONS

         Section 10.1. Any Options and shares of Common Stock issued pursuant to
this 1999 Plan shall be subject to such restrictions on transfer and limitations
as shall,  in the opinion of the  Administrator,  be  necessary  or advisable to
assure  compliance  with the laws,  rules and  regulations  of the United States
government or any state or jurisdiction thereof. In addition,  the Administrator
may in any Stock Option Certificate and Agreement impose such other restrictions
upon  the  disposition  or  exercise  of an  Option  or upon  the  sale or other
disposition of the shares of Common Stock  deliverable  upon exercise thereof as
the Administrator may, in its sole discretion,  determine. By accepting an award
pursuant  to this 1999  Plan,  each  Optionee  shall  thereby  agree to any such
restrictions.

         Section 10.2. Any certificate issued to evidence shares of Common Stock
issued  pursuant  to an Option  shall bear such  legends and  statements  as the
Committee, the Board of Directors or counsel to the Company shall deem advisable
to assure  compliance with the laws,  rules and regulations of the United States
government or any state or jurisdiction  thereof. No shares of Common Stock will
be delivered  pursuant to exercise of the Options  granted  under this 1999 Plan
until the Company has obtained such consents or approvals  from such  regulatory
bodies of the United States  government or any state or jurisdiction  thereof as
the Committee,  the Board of Directors or counsel to the Company deems necessary
or advisable.

                                   ARTICLE XI
                              FINANCIAL ASSISTANCE

         Section 11.1. The Company is vested with authority under this 1999 Plan
to assist any  employee to whom an Option is granted  hereunder  (including  any
officer or  director of the  Company or any of its  subsidiaries  who is also an
employee)  in the  payment of the  purchase  price  payable on  exercise of such
Option,  by lending the amount of such  purchase  price to such employee on such
terms and at such rates of interest  and upon such  security (or  unsecured)  as
shall have been authorized by or under authority of the Board of Directors.  Any
such assistance  shall comply with the  requirements of Regulation G promulgated
by the Board of the Federal  Reserve  System,  as amended from time to time, and
any other applicable law, rule or regulation.

                              APPLICATION OF FUNDS

         Section  12.1.  The proceeds  received by the Company from the issuance
and sale of Common Stock upon exercise of Options granted  pursuant to this 1999
Plan are to be  added  to the  general  funds  of the  Company  and used for its

                                  ARTICLE XIII
                              EFFECTIVENESS OF PLAN

         Section 13.1.  This 1999 Plan shall become  effective  upon adoption by
the Board of Directors,  and Options may be issued hereunder from and after that
date  subject to the  provisions  of Section  3.3 above.  This 1999 Plan must be
approved  by the  Company's  stockholders  in  accordance  with  the  applicable
provisions  (relating  to the  issuance of stock or  options)  of the  Company's
governing documents and state law or, if no such approval is prescribed therein,
by the affirmative vote of the holders of a majority of the votes cast at a duly
held stockholders  meeting at which a quorum  representing a majority of all the
Company's outstanding voting stock is present and voting (in person or by proxy)
or, without regard to any required time period for approval, by any other method
permitted  by Section 422 of the Code and the  regulations  thereunder.  If such
stockholder  approval is not  obtained  within one year of the  adoption of this
1999 Plan by the Board of  Directors  or within such other time period  required
under  Section 422 of the Code and the  regulations  thereunder,  this 1999 Plan
shall remain in force,  provided  however,  that all Options issued and issuable
hereunder shall automatically be deemed to be Non-Qualified Options.

         IN WITNESS  WHEREOF,  pursuant to the approval of this 1999 Plan by the
Board of Directors, this 1999 Plan is executed and adopted as of the 13th day of
September, 1999.

                                ESSEX CORPORATION
                 1998 STOCK OPTION AND APPRECIATION RIGHTS PLAN

                                    ARTICLE I
                            ESTABLISHMENT AND PURPOSE

         Section I.1. Essex Corporation (the "Company"), a Virginia corporation,
hereby  establishes a stock option and appreciation  rights plan to be named the
Essex  Corporation  1998 Stock  Option and  Appreciation  Rights Plan (the "1998
Plan").

         Section I.2. The purpose of this 1998 Plan is to induce persons who are
officers,  directors,  employees  and  consultants  of the Company or any of its
subsidiaries  who are in a position to  contribute  materially  to the Company's
prosperity  to remain with the  Company,  to offer said persons  incentives  and
rewards in recognition of their contributions to the Company's progress,  and to
encourage said persons to continue to promote the best interests of the Company.
This 1998 Plan  provides  for the grant of options to purchase  shares of common
stock of the  Company,  par value  $.10 per share  (the  "Common  Stock")  which
qualify as incentive  stock options  ("Incentive  Options") under Section 422 of
the Internal  Revenue Code of 1986, as amended (the "Code"),  to persons who are
employees, as well as options which do not so qualify ("Non-Qualified  Options")
to be issued to persons or  consultants,  including those who are not employees.
This 1998 Plan also provides for grants of stock appreciation rights ("SARs") in
connection with the grant of options under this 1998 Plan. Incentive Options and
Non-Qualified  Options  may  be  collectively  referred  to  hereinafter  as the
"Options" as the context may require.

         Section  I.3. All options and other  rights  previously  granted by the
Company under any other plan previously adopted by the Company shall continue to
be governed by such plan.  All Options  granted  hereunder  on or after the date
that this 1998 Plan has been  approved  and  adopted by the  Company's  board of
directors  (the  "Board  of  Directors")  shall be  governed  by the  terms  and
conditions  of this  1998 Plan  unless  the  terms of such  Option  specifically
indicate that it is not to be so governed.

                                   ARTICLE II
                                 ADMINISTRATION

         Section II.1. All  determinations  under this 1998 Plan  concerning the
selection  of persons  eligible to receive  awards under this 1998 Plan and with
respect to the timing, pricing and amount of an award under this 1998 Plan shall
be made by the  administrator  (the  "Administrator")  of this  1998  Plan.  The
Administrator  shall  be  either:  (a)  the  Board  of  Directors  or (b) in the
discretion  of the Board of Directors by a committee  (the  "Committee")  of the
Board of  Directors of two or more  members of the Board of  Directors,  each of
whom is a "Non-Employee director" as such term is defined by Rule 16b-3 (as such
rule may be  amended  from time to time,  "Rule  16b-3")  under  the  Securities
Exchange Act of 1934, as amended (the "Exchange  Act"). In such case, a majority
of the total number of members of the Committee shall be necessary to constitute
a quorum;  and (i) the  affirmative  act of a majority of the members present at
any meeting at which a quorum is present,  or (ii) the  approval in writing by a
majority of the members of the Committee shall be necessary to constitute action
by the Committee.

         With  respect to persons  subject  to Section 16 of the  Exchange  Act,
transactions  under this 1998 Plan are  intended to comply  with all  applicable
conditions of Rule 16b-3 or its successors under the Exchange Act. To the extent
that any provision of this 1998 Plan or action by the Administrator  fails to so
comply,  it shall be deemed to be null and void, to the extent  permitted by law
and deemed advisable by the Administrator.

         Section  II.2.  The  provisions of this 1998 Plan relating to Incentive
Options are  intended to comply in every  respect  with  Section 422 of the Code
("Section 422") and the regulations  promulgated  thereunder.  In the event that
any future statute or regulation  shall modify Section 422, this 1998 Plan shall
be deemed to  incorporate  by  reference  such  modification.  Any stock  option
agreement  relating to the grant of any Incentive  Option  pursuant to this 1998
Plan, which option is outstanding and unexercised at the time that any modifying
statute or regulation becomes effective,  shall also be deemed to incorporate by
reference such modification, and no notice of such modification need be given to
the Optionee (as hereinafter defined). Any stock option agreement relating to an
Incentive  Option shall provide that the Optionee (as hereinafter  defined) hold
the stock received upon exercise of such  Incentive  Option for a minimum of two
years from the date of grant of the Incentive  Option and one year from the date
of exercise of such Incentive Option,  absent the written  approval,  consent or
waiver of the Administrator.


<PAGE>

         Section  II.3.  If any  provision  of this 1998 Plan is  determined  to
disqualify the shares of Common Stock  purchasable upon exercise of an Incentive
Option  granted under this 1998 Plan from the special tax treatment  provided by
Section 422,  such  provision  shall be deemed to  incorporate  by reference the
modification  required  to  qualify  such  shares of  Common  Stock for said tax
treatment.

         Section  II.4.  The Company shall grant Options under this 1998 Plan in
accordance  with  determinations  made  by  the  Administrator  pursuant  to the
provisions  of this 1998 Plan.  All Options  granted  pursuant to this 1998 Plan
shall be clearly identified as Incentive Options or Non-Qualified  Options.  The
Administrator may from time to time adopt (and thereafter amend or rescind) such
rules and  regulations  for  carrying out this 1998 Plan and take such action in
the  administration  of this 1998 Plan,  not  inconsistent  with the  provisions
hereof,  as it shall deem  proper.  The Board of  Directors  or,  subject to the
supervision  of the Board of Directors,  the  Committee,  as the  Administrator,
shall have plenary  discretion,  subject to the express  provisions of this 1998
Plan, to determine which officers, directors, employees and consultants shall be
granted Options,  the number of shares subject to each Option, the time or times
when an Option may be exercised  (whether in whole or in installments),  whether
Rights under  Section 7.6 hereof shall be granted,  the terms and  provisions of
the respective option  agreements (which need not be identical),  including such
terms  and  provisions  which  may be  amended  from  time to time as  shall  be
required, in the judgment of the Administrator,  to conform to any change in any
law or regulation applicable hereto, and to make all other determinations deemed
necessary  or  advisable  for  the   administration   of  this  1998  Plan.  The
interpretation  and  construction  of any  provision  of this  1998  Plan by the
Administrator  (unless otherwise  determined by the Board of Directors) shall be
final, conclusive and binding upon all persons.

         Section  II.5. No member of the  Administrator  shall be liable for any
action or  determination  made in good faith with respect to  administration  of
this 1998 Plan or the Options granted  hereunder.  A member of the Administrator
shall be indemnified by the Company,  pursuant to the Company's bylaws,  for any
expenses,  judgments  or other  costs  incurred  as a result of a lawsuit  filed
against such member claiming any rights or remedies arising out of such member's
participation in the administration of this 1998 Plan.

                                   ARTICLE III
                      TOTAL NUMBER OF SHARES TO BE OPTIONED

         Section  III.1.  There shall be reserved for issuance or transfer  upon
exercise  of  Options  to be  granted  from time to time under this 1998 Plan an
aggregate  of  300,000  shares  of  Common  Stock  of the  Company  (subject  to
adjustment as provided in Article VIII hereof).  The shares issued upon exercise
of any  Options  granted  under  this 1998  Plan may be  shares of Common  Stock
previously  issued and  reacquired by the Company at any time or authorized  but
unissued shares of Common Stock, as the Board of Directors from time to time may
determine.

         Section  III.2.  In the event that any Options  outstanding  under this
1998 Plan for any reason expire or are terminated  without having been exercised
in full or shares of Common Stock subject to Options are surrendered in whole or
in part  pursuant to Rights  granted  under  Section  7.6 hereof  (except to the
extent  that  shares of Common  Stock are issued as payment to the holder of the
Option upon such  surrender) the  unpurchased  shares of Common Stock subject to
such  Option  and any such  surrendered  shares  of  Common  Stock  may again be
available for transfer under this 1998 Plan.

         Section III.3.  No Options shall be granted  pursuant to this 1998 Plan
to any Optionee  after the tenth  anniversary of the date that this 1998 Plan is
adopted by the Board of Directors.

                                   ARTICLE IV
                                   ELIGIBILITY

         Section  IV.1.  Non-Qualified  Options may be granted  pursuant to this
1998 Plan to officers,  directors,  employees and consultants of the Company (or
any of its subsidiaries)  selected by the  Administrator,  and Incentive Options
may be granted pursuant to this 1998 Plan only to employees  (including officers
and  directors  who  are  also   employees)  of  the  Company  (or  any  of  its
subsidiaries) selected by the Administrator. Persons granted Options pursuant to
this  1998  Plan  are  referred  to  herein  as  "Optionees."  For  purposes  of
determining  who is an  employee  with  respect  to  eligibility  for  Incentive
Options,  Section 422 shall govern. The Administrator may determine (in its sole
discretion)  that any  person  who would  otherwise  be  eligible  to be granted
Options shall,  nonetheless,  be ineligible to receive any award under this 1998
Plan.

         Section IV.2. The Administrator will (in its discretion)  determine the
persons  to be  granted  Options,  the time or times at which  Options  shall be
granted,  the number of shares of Common Stock subject to each Option, the terms
of a vesting or  forfeiture  schedule,  if any, the type of Option  issued,  the
period during which such Options may be  exercised,  the manner in which Options
may be exercised and all other terms and  conditions  of the Options;  provided,
however,  no Option will be granted which has terms or  conditions  inconsistent
with those stated in Articles V and VI hereof.  Relevant  factors in making such
determinations  may include the value of the services rendered by the respective
Optionee,  his or her present and potential  contributions  to the Company,  and
such other factors  which are deemed  relevant in  accomplishing  the purpose of
this 1998 Plan.

                                    ARTICLE V
                         TERMS AND CONDITIONS OF OPTIONS

         Section  V.1.  Each  Option  granted  under  this  1998  Plan  shall be
evidenced  by a stock  option  certificate  and  agreement  (the  "Stock  Option
Certificate and  Agreement") in a form consistent with this 1998 Plan,  provided
that the following terms and conditions shall apply:

         (a) The price at which each share of Common Stock  covered by an Option
may be  purchased  shall  be set  forth  in the  Stock  Option  Certificate  and
Agreement and shall be determined by the Administrator, provided that the option
price for any Incentive Option shall not be less than the "fair market value" of
the shares of Common Stock at the time of grant  determined in  accordance  with
Section 5.1(b) below.  Notwithstanding the foregoing,  if an Incentive Option to
purchase  shares of Common  Stock is  granted  pursuant  to this 1998 Plan to an
Optionee who, on the date of the grant,  directly or  indirectly  owns more than
ten percent  (10%) of the voting  power of all  classes of capital  stock of the
Company (or its parent or subsidiary),  not including the shares of Common Stock
obtainable  upon  exercise of the Option,  the  minimum  exercise  price of such
Option shall be not less than one hundred ten percent (110%) of the "fair market
value"  of the  shares  of  Common  Stock  on the date of  grant  determined  in
accordance with Section 5.1(b) below.

         (b) The "fair market value" shall be  determined by the  Administrator,
which  determination  shall  be  binding  upon  the  Company  and its  officers,
directors, employees and consultants. The determination of the fair market value
shall be based upon the  following:  (i) if the  shares of Common  Stock are not
listed and traded upon a recognized  securities  exchange and there is no report
of stock  prices  with  respect to the  shares of Common  Stock  published  by a
recognized  stock quotation  service,  on the basis of the recent  purchases and
sales of the shares of Common Stock in arms-length transactions;  or (ii) if the
shares  of  Common  Stock  are not then  listed  and  traded  upon a  recognized
securities  exchange or quoted on the NASDAQ Stock Market, and there are reports
of stock prices by a recognized  quotation  service,  upon the basis of the last
reported  sale or  transaction  price  of such  stock  on the  date of  grant as
reported by a recognized  quotation  service,  or, if there is no last  reported
sale or  transaction  price on that day,  then upon the basis of the mean of the
last reported closing bid and closing asked prices for such stock on that day or
on the date nearest  preceding  that day; or (iii) if the shares of Common Stock
shall then be listed and traded upon a recognized  securities exchange or quoted
on the  NASDAQ  Stock  Market,  upon  the  basis of the  last  reported  sale or
transaction price at which shares of Common Stock were traded on such recognized
securities  exchange on the date of grant or, if the shares of Common Stock were
not traded on such date, upon the basis of the last reported sale or transaction
price on the date nearest  preceding  that date.  The  Administrator  shall also
consider such other  factors  relating to the fair market value of the shares of
Common Stock as it shall deem appropriate.

                                      iii

<PAGE>

         (c) For the purpose of  determining  whether an Optionee owns more than
ten percent (10%) of the voting power of all classes of stock of the Company, an
Optionee  is  considered  to own  those  shares  which  are  owned  directly  or
indirectly  through  brothers  and sisters  (including  half-blooded  siblings),
spouse,  ancestors and lineal descendants;  and proportionately as a shareholder
of a corporation, a partner of a partnership, and/or a beneficiary of a trust or
an estate that owns shares of the Company.

         (d)   Notwithstanding  any  other  provision  of  this  1998  Plan,  in
accordance with the provisions of Section 422(d) of the Code, to the extent that
the aggregate  fair market value  (determined at the time the Option is granted)
of the shares of Common  Stock of the Company  with  respect to which  Incentive
Options (without reference to this provision) are exercisable for the first time
by any  individual  in any calendar year under any and all stock option plans of
the  Company,  its  subsidiary  corporations  and its  parent  (if any)  exceeds
$100,000, such Options shall be treated as Non-Qualified Options.

         (e) An Optionee may, in the Administrator's discretion, be granted more
than one Incentive  Option or  Non-Qualified  Option during the duration of this
1998  Plan,  and may be  issued  a  combination  of  Non-Qualified  Options  and
Incentive  Options;  provided,  however,  that non-employees are not eligible to
receive Incentive Options.

         (f) The duration of any Option and any Right  related  thereto shall be
within the sole discretion of the  Administrator;  provided,  however,  that any
Incentive  Option  granted to a ten  percent  (10%) or less  stockholder  or any
Non-Qualified  Option shall, by its terms,  be exercised  within ten years after
the date the Option is granted  and any  Incentive  Option  granted to a greater
than ten percent (10%) stockholder shall, by its terms, be exercised within five
years after the date the Option is granted.

         (g) An Option and any Right related  thereto shall not be  transferable
by the Optionee other than by will, or by the laws of descent and  distribution.
An Option may be exercised during the Optionee's lifetime only by the Optionee.

         (h) The  Administrator  may impose such other or further  conditions on
any transaction under the 1998 Plan, including without limitation,  the grant or
award of any Option or the exercise or other disposition  thereof, as it, in its
discretion,  may deem necessary or advisable in order to exempt the  transaction
from Section 16(b) of the Exchange Act,  including without  limitation  thereto,
the approval or  ratification  of the transaction by shareholders or a six-month
restriction  on  disposition  of the Option or the Common  Stock  issuable  upon
exercise thereof.

                                   ARTICLE VI
                        EMPLOYMENT OR SERVICE OF OPTIONEE

         Section VI.1. If the employment or service of an Optionee is terminated
for cause,  the option rights of such Optionee,  both accrued and future,  under
any  then   outstanding   Non-Qualified  or  Incentive  Option  shall  terminate
immediately.  "Cause"  shall mean  incompetence  in the  performance  of duties,
disloyalty, dishonesty, theft, embezzlement, unauthorized disclosure of patents,
processes  or trade  secrets of the  Company,  individually  or as an  employee,
partner, associate,  officer or director of any organization.  The determination
of the  existence  and the proof of "cause"  shall be made by the  Administrator
and, subject to the review of any determination made by the Administrator,  such
determination shall be binding on the Optionee and the Company.

         Section  VI.2.  If  the  employment  or  service  of  the  Optionee  is
terminated  by either the  Optionee or the Company for any reason other than for
cause,  death,  retirement or for disability,  as defined in Section 22(e)(3) of
the  Code,  the  option  rights  of such  Optionee  under  any then  outstanding
Incentive Option shall,  subject to the provisions of Section 5.1(h) hereof,  be
exercisable  by such Optionee at any time prior to the  expiration of the Option
or within three months after the date of such  termination,  whichever period of
time is  shorter,  but only to the extent of the accrued  right to exercise  the
Option at the date of such termination.

         Section  VI.3.  In the case of an  Optionee  who becomes  disabled,  as
defined by Section  22(e)(3)  of the Code,  the option  rights of such  Optionee
under any then outstanding  Incentive Option shall, subject to the provisions of
Section 5.1(h) hereof,  be exercisable by such Optionee at any time prior to the
expiration  of the Option or within one year  after the date of  termination  of
employment or service due to  disability,  whichever  period of time is shorter,
but only to the extent of the accrued  right to exercise  the Option at the date
of such termination.

                                       iv

<PAGE>

         Section  VI.4.  In the event of the death of an  Optionee,  the  option
rights of such Optionee  under any then  outstanding  Incentive  Option shall be
exercisable by the person or persons to whom these rights pass by will or by the
laws of descent and  distribution,  at any time prior to the  expiration  of the
Option or within three years after the date of death,  whichever  period of time
is shorter,  but only to the extent of the accrued  right to exercise the Option
at the date of death.  If a person or estate  acquires  the right to exercise an
Incentive  Option by bequest  or  inheritance,  the  Administrator  may  require
reasonable  evidence as to the  ownership of such  Option,  and may require such
consents  and  releases  of taxing  authorities  as the  Administrator  may deem
advisable.

         Section  VI.5.  If an Optionee to whom an Option has been granted under
this 1998 Plan retires from his employment or service with the Company or any of
the  Subsidiaries  under a  retirement  plan or  policy of the  Company  and its
Subsidiaries  or at his or her  normal  retirement  date  or  earlier  with  the
approval  or consent of the  Company or such  Subsidiary,  or as a result of the
Disability  as  defined in  Section  22(e)(3)  of the Code,  such  Option  shall
continue  to be  exercisable  in whole or in part,  to the extent not  therefore
exercised,  by the Optionee to whom granted in the manner set forth in this 1998
Plan, at any time within the remaining term of such Option.

         Section VI.6. The  Administrator may also provide that an employee must
be  continuously  employed  by the  Company  for  such  period  of  time  as the
Administrator,  in its discretion,  deems advisable before the right to exercise
any portion of an Option granted to such employee will accrue,  and may also set
such other  targets,  restrictions  or other terms relating to the employment of
the Optionee which targets, restrictions, or terms must be fulfilled or complied
with,  as the case may be,  prior to the  exercise  of any  portion of an Option
granted to any employee.

         Section  VI.7.   Except  in  the  event  of   termination   for  cause,
Non-Qualified Options shall be exercisable during such term as determined at the
time of grant by the Administrator.

         Section  VI.8.  Options  granted  under  this  1998  Plan  shall not be
affected by any change of duties or position,  so long as the Optionee continues
in the service of the Company.

         Section  VI.9.  Nothing  contained in this 1998 Plan,  or in any Option
granted  pursuant to this 1998 Plan,  shall  confer upon any  Optionee any right
with  respect  to  continuance  of  employment  or service  by the  Company  nor
interfere in any way with the right of the Company to terminate  the  Optionee's
employment or service or change the Optionee's compensation at any time.

                                   ARTICLE VII
                               PURCHASE OF SHARES

         Section VII.1.  Except as provided in this Article VII, an Option shall
be exercised by tender to the Company of the full  exercise  price of the shares
of Common Stock with respect to which the Option is exercised and written notice
of the  exercise.  The  right  to  purchase  shares  of  Common  Stock  shall be
cumulative  so that,  once the right to purchase  any shares of Common Stock has
accrued, such shares or any part thereof may be purchased at any time thereafter
until the  expiration or  termination  of the Option.  A partial  exercise of an
Option  shall not affect the right of the  Optionee to exercise  the Option from
time to time, in accordance  with this 1998 Plan, as to the remaining  number of
shares of Common Stock subject to the Option.  The purchase  price of the shares
shall be in United States  dollars,  payable in cash or by certified bank check.
Notwithstanding  the  foregoing,  in lieu of cash,  an  Optionee  may,  with the
approval of the  Administrator,  exercise  his or her Option by tendering to the
Company  shares of Common Stock of the Company owned by him or her and having an
aggregate fair market value at least equal to the full exercise price.  The fair
market value of any shares of Common Stock so surrendered shall be determined by
the Administrator in accordance with Section 5.1(b) hereof.

         Section  VII.2.  Except as provided in Article VI above,  an Option may
not be exercised unless the holder thereof is an officer, director, employee, or
consultant of the Company at the time of exercise.

         Section  VII.3.  No Optionee,  or Optionee's  executor,  administrator,
legatee, or distributee or other permitted  transferee,  shall be deemed to be a
holder of any  shares of  Common  Stock  subject  to an Option  for any  purpose
whatsoever  unless and until a stock certificate or certificates for such shares
are issued to such person under the terms of this 1998 Plan. No adjustment shall
be made for dividends (ordinary or extraordinary, whether in cash, securities or

                                       v

<PAGE>

other  property) or  distributions  or other rights for which the record date is
prior to the date such  stock  certificate  is  issued,  except as  provided  in
Article VIII hereof.

         Section VII.4.  If: (i) the listing,  registration or  qualification of
the Options issued  hereunder,  or of any  securities  issuable upon exercise of
such  Options  (the  "Subject  Securities")  upon  any  securities  exchange  or
quotation system or under federal or state law is necessary as a condition of or
in connection with the issuance or exercise of the Options,  or (ii) the consent
or approval of any  governmental  regulatory body is necessary as a condition of
or in connection with the issuance or exercise of the Options, the Company shall
not be obligated to deliver the certificates representing the Subject Securities
or to accept or to recognize an Option  exercise  unless and until such listing,
registration,  qualification,  consent or approval  shall have been  effected or
obtained.  The Company  will take  reasonable  action to so list,  register,  or
qualify the Options and the Subject Securities, or effect or obtain such consent
or approval, so as to allow for their issuance.

         Section VII.5.  An Optionee may be required to represent to the Company
as a condition  of his or her  exercise of Options  issued  under this 1998 Plan
that: (i) the Subject Securities acquired upon exercise of his or her Option are
being acquired by him or her for investment purposes only and not with a view to
distribution or resale,  unless counsel for the Company is then of the view that
such a representation  is not necessary and is not required under the Securities
Act of 1933, as amended (the "Securities Act"), or any other applicable statute,
law,  regulation or rule;  and (ii) that the Optionee  shall make no exercise or
disposition of an Option or of the Subject  Securities in  contravention  of the
Securities  Act,  the  Exchange  Act or the  rules and  regulations  thereunder.
Optionees may also be required to provide (as a condition  precedent to exercise
of an Option) such  documentation as may be reasonably  requested by the Company
to assure  compliance  with  applicable law and the terms and conditions of this
1996 Plan and the subject Option.

         Section  VII.6.  The  Administrator  may, in its  discretion,  grant in
connection with any Option, at any time prior to the exercise thereof, the right
(previously defined as an "SAR" or collectively, the "SARs") to surrender all or
part of the Option to the extent that such Option is exercisable  and receive in
exchange an amount  (payable in cash,  shares of Common Stock valued at the then
fair market value, or a combination  thereof as determined by the Administrator)
equal to the difference (the "Spread") between the then fair market value of the
shares of Common  Stock  issuable  upon the  exercise of the Option (or portions
thereof  surrendered)  and the option  price  payable  upon the  exercise of the
Option (or portions thereof surrendered). Such SARs may be included in an Option
only under the following conditions:  (a) the SARs will expire no later than the
expiration of the  underlying  Option;  (b) the SARs may be for no more than one
hundred percent (100%) of the Spread;  (c) the SARs are  transferable  only when
the underlying  Option is transferable  and under the same  conditions;  (d) the
SARs may be  exercised  only  when  the  underlying  Option  is  eligible  to be
exercised;  and (e) the SARs may be exercised  only when the Spread is positive,
i.e.,  when the market  price of the stock  subject to the  Option  exceeds  the
exercise price of the Option.

         Section VII.7. An Option may also be exercised by tender to the Company
of a written notice of exercise together with advice of the delivery of an order
to a broker to sell part or all of the  shares of Common  Stock  subject to such
exercise  notice  and an  irrevocable  order to such  broker to  deliver  to the
Company (or its transfer agent) sufficient proceeds from the sale of such shares
to pay the exercise  price and any  withholding  taxes.  All  documentation  and
procedures to be followed in connection with such a "cashless exercise" shall be
approved in advance by the Administrator.

                                  ARTICLE VIII
                    CHANGE IN NUMBER OF OUTSTANDING SHARES OF
                    STOCK, ADJUSTMENTS, REORGANIZATIONS, ETC.

         Section  VIII.1.  In the event  that the  outstanding  shares of Common
Stock of the Company are  hereafter  increased  or  decreased or changed into or
exchanged for a different number of shares or kind of shares or other securities
of the Company or of another  corporation by reason of  reorganization,  merger,
consolidation,  recapitalization,  reclassification, stock split, combination of
shares, or a dividend payable in capital stock,  appropriate adjustment shall be
made by the  Administrator  in the number and kind of shares for the purchase of
which Options may be granted under this 1998 Plan,  including the maximum number
that may be granted to any one person. In addition, the Administrator shall make
appropriate adjustments in the number and kind of shares as to which outstanding
Options, or portions thereof then unexercised,  shall be exercisable, to the end
that the  Optionee's  proportionate  interest  shall be maintained as

                                       vi

<PAGE>

before  the  occurrence  to the  unexercised  portion  of the  Option and with a
corresponding adjustment in the option price per share. Any such adjustment made
by the Administrator shall be conclusive.

         Section VIII.2. The grant of an Option pursuant to this 1998 Plan shall
not  affect in any way the right or power of the  Company  to make  adjustments,
reclassifications,  reorganizations  or  changes  of  its  capital  or  business
structure or to merge or to  consolidate  or to dissolve,  liquidate or sell, or
transfer all or any part of its business or assets.

         Section VIII.3.  Upon the dissolution or liquidation of the Company, or
upon a  reorganization,  merger or  consolidation  of the Company as a result of
which the outstanding  securities of the class then subject to Options hereunder
are changed  into or  exchanged  for cash or property or  securities  not of the
Company's issue, or upon a sale of substantially all the property of the Company
to an association, person, party, corporation,  partnership, or control group as
that term is construed  for purposes of the Exchange  Act,  this 1998 Plan shall
terminate,  and all  outstanding  Options  theretofore  granted  hereunder shall
terminate,  unless  provision  be  made  in  writing  in  connection  with  such
transaction  for the  continuance of this 1998 Plan and/or for the assumption of
Options  theretofore  granted,  or the  substitution for such Options of options
covering  the  stock of a  successor  employer  corporation,  or a  parent  or a
subsidiary  thereof,  with appropriate  adjustments as to the number and kind of
shares and prices, in which event this 1998 Plan and options theretofore granted
shall continue in the manner and under the terms so provided.  If this 1998 Plan
and unexercised Options shall terminate pursuant to the foregoing sentence,  all
persons owning any unexercised  portions of Options then outstanding  shall have
the right, at such time prior to the  consummation  of the  transaction  causing
such  termination as the Company shall  designate,  to exercise the  unexercised
portions of their Options,  including the portions  thereof which would, but for
this Section 8.3 not yet be exercisable.

                                   ARTICLE IX
                       DURATION, AMENDMENT AND TERMINATION

         Section  IX.1.  The Board of Directors may at any time  terminate  this
1998 Plan or make such  amendments  hereto as it shall deem advisable and in the
best interests of the Company, without action on the part of the stockholders of
the Company unless such approval is required pursuant to Section 422 of the Code
or the regulations thereunder or other federal or state law; provided,  however,
that  no such  termination  or  amendment  shall,  without  the  consent  of the
individual to whom any Option shall  theretofore  have been granted,  materially
adversely  affect or impair the  rights of such  individual  under such  Option.
Pursuant  to  Section  422(b) of the Code,  no  Incentive  Option may be granted
pursuant  to this  1998 Plan  after  ten  years  from the date this 1998 Plan is
adopted  or the date this  1998  Plan is  approved  by the  stockholders  of the
Company, whichever is earlier.

                                    ARTICLE X
                                  RESTRICTIONS

         Section X.1. Any Options and shares of Common Stock issued  pursuant to
this 1998 Plan shall be subject to such restrictions on transfer and limitations
as shall,  in the opinion of the  Administrator,  be  necessary  or advisable to
assure  compliance  with the laws,  rules and  regulations  of the United States
government or any state or jurisdiction thereof. In addition,  the Administrator
may in any Stock Option Certificate and Agreement impose such other restrictions
upon  the  disposition  or  exercise  of an  Option  or upon  the  sale or other
disposition of the shares of Common Stock  deliverable  upon exercise thereof as
the Administrator may, in its sole discretion,  determine. By accepting an award
pursuant  to this 1998  Plan,  each  Optionee  shall  thereby  agree to any such
restrictions.

         Section X.2. Any certificate  issued to evidence shares of Common Stock
issued  pursuant  to an Option  shall bear such  legends and  statements  as the
Committee, the Board of Directors or counsel to the Company shall deem advisable
to assure  compliance with the laws,  rules and regulations of the United States
government or any state or jurisdiction  thereof. No shares of Common Stock will
be delivered  pursuant to exercise of the Options  granted  under this 1998 Plan
until the Company has obtained such consents or approvals  from such  regulatory
bodies of the United States  government or any state or jurisdiction  thereof as
the Committee,  the Board of Directors or counsel to the Company deems necessary
or advisable.

                              FINANCIAL ASSISTANCE

         Section XI.1. The Company is vested with authority under this 1998 Plan
to assist any  employee to whom an Option is granted  hereunder  (including  any
officer or  director of the  Company or any of its  subsidiaries  who is also an
employee)  in the  payment of the  purchase  price  payable on  exercise of such
Option,  by lending the amount of such  purchase  price to such employee on such
terms and at such rates of interest  and upon such  security (or  unsecured)  as
shall have been authorized by or under authority of the Board of Directors.  Any
such assistance  shall comply with the  requirements of Regulation G promulgated
by the Board of the Federal  Reserve  System,  as amended from time to time, and
any other applicable law, rule or regulation.

         Section XII.1.  The proceeds  received by the Company from the issuance
and sale of Common Stock upon exercise of Options granted  pursuant to this 1998
Plan are to be  added  to the  general  funds  of the  Company  and used for its
corporate purposes as determined by the Board of Directors.

                                  ARTICLE XIII
                              EFFECTIVENESS OF PLAN

         Section XIII.1.  This 1998 Plan shall become effective upon adoption by
the Board of Directors,  and Options may be issued hereunder from and after that
date  subject to the  provisions  of Section  3.3 above.  This 1998 Plan must be
approved  by the  Company's  stockholders  in  accordance  with  the  applicable
provisions  (relating  to the  issuance of stock or  options)  of the  Company's
governing documents and state law or, if no such approval is prescribed therein,
by the affirmative vote of the holders of a majority of the votes cast at a duly
held stockholders  meeting at which a quorum  representing a majority of all the
Company's outstanding voting stock is present and voting (in person or by proxy)
or, without regard to any required time period for approval, by any other method
permitted  by Section 422 of the Code and the  regulations  thereunder.  If such
stockholder  approval is not  obtained  within one year of the  adoption of this
1998 Plan by the Board of  Directors  or within such other time period  required
under  Section 422 of the Code and the  regulations  thereunder,  this 1998 Plan
shall remain in force,  provided  however,  that all Options issued and issuable
hereunder shall automatically be deemed to be Non-Qualified Options.

         IN WITNESS  WHEREOF,  pursuant to the approval of this 1998 Plan by the
Board of Directors,  this 1998 Plan is executed and adopted as of the 7th day of
August, 1998.

                                ESSEX CORPORATION
                 1996 STOCK OPTION AND APPRECIATION RIGHTS PLAN

                                    ARTICLE I
                            ESTABLISHMENT AND PURPOSE

         Section I.1. Essex Corporation (the "Company"), a Virginia corporation,
hereby  establishes a stock option and appreciation  rights plan to be named the
Essex  Corporation  1996 Stock  Option and  Appreciation  Rights Plan (the "1996
Plan").

         Section I.2. The purpose of this 1996 Plan is to induce persons who are
officers,  directors,  employees  and  consultants  of the Company or any of its
subsidiaries  who are in a position to  contribute  materially  to the Company's
prosperity  to remain with the  Company,  to offer said persons  incentives  and
rewards in recognition of their contributions to the Company's progress,  and to
encourage said persons to continue to promote the best interests of the Company.
This 1996 Plan  provides  for the grant of options to purchase  shares of common
stock of the  Company,  par value  $.10 per share  (the  "Common  Stock")  which
qualify as incentive  stock options  ("Incentive  Options") under Section 422 of
the Internal  Revenue Code of 1986, as amended (the "Code"),  to persons who are
employees, as well as options which do not so qualify ("Non-Qualified  Options")
to be issued to persons or  consultants,  including those who are not employees.
This 1996 Plan also provides for grants of stock appreciation rights ("SARs") in
connection with the grant of options under this 1996 Plan. Incentive Options and
Non-Qualified  Options  may  be  collectively  referred  to  hereinafter  as the
"Options" as the context may require.

         Section  I.3. All options and other  rights  previously  granted by the
Company under any other plan previously adopted by the Company shall continue to
be governed by such plan.  All Options  granted  hereunder  on or after the date
that this 1996 Plan has been  approved  and  adopted by the  Company's  board of
directors  (the  "Board  of  Directors")  shall be  governed  by the  terms  and
conditions  of this  1996 Plan  unless  the  terms of such  Option  specifically
indicate that it is not to be so governed.

                                   ARTICLE II
                                 ADMINISTRATION

         Section II.1. All  determinations  under this 1996 Plan  concerning the
selection  of persons  eligible to receive  awards under this 1996 Plan and with
respect to the timing, pricing and amount of an award under this 1996 Plan shall
be made by the  administrator  (the  "Administrator")  of this  1996  Plan.  The
Administrator  shall  be  either:  (a)  the  Board  of  Directors  or (b) in the
discretion  of the Board of Directors by a committee  (the  "Committee")  of the
Board of  Directors of two or more  members of the Board of  Directors,  each of
whom is a "Non-Employee Director" as such term is defined by Rule 16b-3 (as such
rule may be  amended  from time to time,  "Rule  16b-3")  under  the  Securities
Exchange Act of 1934, as amended (the "Exchange  Act"). In such case, a majority
of the total number of members of the Committee shall be necessary to constitute
a quorum;  and (i) the  affirmative  act of a majority of the members present at
any meeting at which a quorum is present,  or (ii) the  approval in writing by a
majority of the members of the Committee shall be necessary to constitute action
by the Committee.

         With  respect to persons  subject  to Section 16 of the  Exchange  Act,
transactions  under this 1996 Plan are  intended to comply  with all  applicable
conditions of Rule 16b-3 or its successors under the Exchange Act. To the extent
that any provision of this 1996 Plan or action by the Administrator  fails to so
comply,  it shall be deemed to be null and void, to the extent  permitted by law
and deemed advisable by the Administrator.

         Section  II.2.  The  provisions of this 1996 Plan relating to Incentive
Options are  intended to comply in every  respect  with  Section 422 of the Code
("Section 422") and the regulations  promulgated  thereunder.  In the event that
any future statute or regulation  shall modify Section 422, this 1996 Plan shall
be deemed to  incorporate  by  reference  such  modification.  Any stock  option
agreement  relating to the grant of any Incentive  Option  pursuant to this 1996
Plan, which option is outstanding and unexercised at the time that any modifying
statute or regulation becomes effective,  shall also be deemed to incorporate by
reference such modification, and no notice of such modification need be given to
the Optionee (as hereinafter defined). Any stock option agreement relating to an
Incentive  Option shall provide that the

<PAGE>

Optionee (as hereinafter  defined) hold the stock received upon exercise of such
Incentive  Option  for a  minimum  of two  years  from  the date of grant of the
Incentive  Option  and one  year  from the date of  exercise  of such  Incentive
Option, absent the written approval, consent or waiver of the Administrator.

         Section  II.3.  If any  provision  of this 1996 Plan is  determined  to
disqualify the shares of Common Stock  purchasable upon exercise of an Incentive
Option  granted under this 1996 Plan from the special tax treatment  provided by
Section 422,  such  provision  shall be deemed to  incorporate  by reference the
modification  required  to  qualify  such  shares of  Common  Stock for said tax
treatment.

         Section  II.4.  The Company shall grant Options under this 1996 Plan in
accordance  with  determinations  made  by  the  Administrator  pursuant  to the
provisions  of this 1996 Plan.  All Options  granted  pursuant to this 1996 Plan
shall be clearly identified as Incentive Options or Non-Qualified  Options.  The
Administrator may from time to time adopt (and thereafter amend or rescind) such
rules and  regulations  for  carrying out this 1996 Plan and take such action in
the  administration  of this 1996 Plan,  not  inconsistent  with the  provisions
hereof,  as it shall deem  proper.  The Board of  Directors  or,  subject to the
supervision  of the Board of Directors,  the  Committee,  as the  Administrator,
shall have plenary  discretion,  subject to the express  provisions of this 1996
Plan, to determine which officers, directors, employees and consultants shall be
granted Options,  the number of shares subject to each Option, the time or times
when an Option may be exercised  (whether in whole or in installments),  whether
Rights under  Section 7.6 hereof shall be granted,  the terms and  provisions of
the respective option  agreements (which need not be identical),  including such
terms  and  provisions  which  may be  amended  from  time to time as  shall  be
required, in the judgment of the Administrator,  to conform to any change in any
law or regulation applicable hereto, and to make all other determinations deemed
necessary  or  advisable  for  the   administration   of  this  1996  Plan.  The
interpretation  and  construction  of any  provision  of this  1996  Plan by the
Administrator  (unless otherwise  determined by the Board of Directors) shall be
final, conclusive and binding upon all persons.

         Section  II.5. No member of the  Administrator  shall be liable for any
action or  determination  made in good faith with respect to  administration  of
this 1996 Plan or the Options granted  hereunder.  A member of the Administrator
shall be indemnified by the Company,  pursuant to the Company's bylaws,  for any
expenses,  judgments  or other  costs  incurred  as a result of a lawsuit  filed
against such member claiming any rights or remedies arising out of such member's
participation in the administration of this 1996 Plan.

                                   ARTICLE III
                      TOTAL NUMBER OF SHARES TO BE OPTIONED

         Section  III.1.  There shall be reserved for issuance or transfer  upon
exercise  of  Options  to be  granted  from time to time under this 1996 Plan an
aggregate  of  300,000  shares  of  Common  Stock  of the  Company  (subject  to
adjustment as provided in Article VIII hereof).  The shares issued upon exercise
of any  Options  granted  under  this 1996  Plan may be  shares of Common  Stock
previously  issued and  reacquired by the Company at any time or authorized  but
unissued shares of Common Stock, as the Board of Directors from time to time may
determine.

         Section  III.2.  In the event that any Options  outstanding  under this
1996 Plan for any reason expire or are terminated  without having been exercised
in full or shares of Common Stock subject to Options are surrendered in whole or
in part  pursuant to Rights  granted  under  Section  7.6 hereof  (except to the
extent  that  shares of Common  Stock are issued as payment to the holder of the
Option upon such  surrender) the  unpurchased  shares of Common Stock subject to
such  Option  and any such  surrendered  shares  of  Common  Stock  may again be
available for transfer under this 1996 Plan.

         Section III.3.  No Options shall be granted  pursuant to this 1996 Plan
to any Optionee  after the tenth  anniversary of the date that this 1996 Plan is
adopted by the Board of Directors.

                                   ARTICLE IV
                                   ELIGIBILITY

         Section  IV.1.  Non-Qualified  Options may be granted  pursuant to this
1996 Plan to officers,  directors,  employees and consultants of the Company (or
any of its subsidiaries)  selected by the  Administrator,  and Incentive Options
may be granted pursuant to this 1996 Plan only to employees  (including officers
and  directors  who  are  also   employees)  of  the  Company  (or  any  of  its
subsidiaries) selected by the Administrator. Persons granted Options pursuant to
this  1996  Plan  are  referred  to  herein  as  "Optionees."  For  purposes  of
determining  who is an  employee  with  respect  to  eligibility  for  Incentive
Options,  Section 422 shall govern. The Administrator may determine (in its sole
discretion)  that any  person  who would  otherwise  be  eligible  to be granted
Options shall,  nonetheless,  be ineligible to receive any award under this 1996
Plan.

         Section IV.2. The Administrator will (in its discretion)  determine the
persons  to be  granted  Options,  the time or times at which  Options  shall be
granted,  the number of shares of Common Stock subject to each Option, the terms
of a vesting or  forfeiture  schedule,  if any, the type of Option  issued,  the
period during which such Options may be  exercised,  the manner in which Options
may be exercised and all other terms and  conditions  of the Options;  provided,
however,  no Option will be granted which has terms or  conditions  inconsistent
with those stated in Articles V and VI hereof.  Relevant  factors in making such
determinations  may include the value of the services rendered by the respective
Optionee,  his or her present and potential  contributions  to the Company,  and
such other factors  which are deemed  relevant in  accomplishing  the purpose of
this 1996 Plan.

                                    ARTICLE V
                         TERMS AND CONDITIONS OF OPTIONS

         Section  V.1.  Each  Option  granted  under  this  1996  Plan  shall be
evidenced  by a stock  option  certificate  and  agreement  (the  "Stock  Option
Certificate and  Agreement") in a form consistent with this 1996 Plan,  provided
that the following terms and conditions shall apply:

         (a) The price at which each share of Common Stock  covered by an Option
may be  purchased  shall  be set  forth  in the  Stock  Option  Certificate  and
Agreement and shall be determined by the Administrator, provided that the option
price for any Incentive Option shall not be less than the "fair market value" of
the shares of Common Stock at the time of grant  determined in  accordance  with
Section 5.1(b) below.  Notwithstanding the foregoing,  if an Incentive Option to
purchase  shares of Common  Stock is  granted  pursuant  to this 1996 Plan to an
Optionee who, on the date of the grant,  directly or  indirectly  owns more than
ten percent  (10%) of the voting  power of all  classes of capital  stock of the
Company (or its parent or subsidiary),  not including the shares of Common Stock
obtainable  upon  exercise of the Option,  the  minimum  exercise  price of such
Option shall be not less than one hundred ten percent (110%) of the "fair market
value"  of the  shares  of  Common  Stock  on the date of  grant  determined  in
accordance with Section 5.1(b) below.

         (b) The "fair market value" shall be  determined by the  Administrator,
which  determination  shall  be  binding  upon  the  Company  and its  officers,
directors, employees and consultants. The determination of the fair market value
shall be based upon the  following:  (i) if the  shares of Common  Stock are not
listed and traded upon a recognized  securities  exchange and there is no report
of stock  prices  with  respect to the  shares of Common  Stock  published  by a
recognized  stock quotation  service,  on the basis of the recent  purchases and
sales of the shares of Common Stock in arms-length transactions;  or (ii) if the
shares  of  Common  Stock  are not then  listed  and  traded  upon a  recognized
securities  exchange or quoted on the NASDAQ Stock Market, and there are reports
of stock prices by a recognized  quotation  service,  upon the basis of the last
reported  sale or  transaction  price  of such  stock  on the  date of  grant as
reported by a recognized  quotation  service,  or, if there is no last  reported
sale or  transaction  price on that day,  then upon the basis of the mean of the
last reported closing bid and closing asked prices for such stock on that day or
on the date nearest  preceding  that day; or (iii) if the shares of Common Stock
shall then be listed and traded upon a recognized  securities exchange or quoted
on the  NASDAQ  Stock  Market,  upon  the  basis of the  last  reported  sale or
transaction price at which shares of Common Stock were traded on such recognized
securities  exchange on the date of grant or, if the shares of Common Stock were
not traded on such date, upon the basis of the last reported sale or transaction
price on

                                      iii

the date nearest preceding that date. The Administrator shall also consider such
other factors relating to the fair market value of the shares of Common Stock as
it shall deem appropriate.

         (c) For the purpose of  determining  whether an Optionee owns more than
ten percent (10%) of the voting power of all classes of stock of the Company, an
Optionee  is  considered  to own  those  shares  which  are  owned  directly  or
indirectly  through  brothers  and sisters  (including  half-blooded  siblings),
spouse,  ancestors and lineal descendants;  and proportionately as a shareholder
of a corporation, a partner of a partnership, and/or a beneficiary of a trust or
an estate that owns shares of the Company.

         (d)   Notwithstanding  any  other  provision  of  this  1996  Plan,  in
accordance with the provisions of Section 422(d) of the Code, to the extent that
the aggregate  fair market value  (determined at the time the Option is granted)
of the shares of Common  Stock of the Company  with  respect to which  Incentive
Options (without reference to this provision) are exercisable for the first time
by any  individual  in any calendar year under any and all stock option plans of
the  Company,  its  subsidiary  corporations  and its  parent  (if any)  exceeds
$100,000, such Options shall be treated as Non-Qualified Options.

         (e) An Optionee may, in the Administrator's discretion, be granted more
than one Incentive  Option or  Non-Qualified  Option during the duration of this
1996  Plan,  and may be  issued  a  combination  of  Non-Qualified  Options  and
Incentive  Options;  provided,  however,  that non-employees are not eligible to
receive Incentive Options.

         (f) The duration of any Option and any Right  related  thereto shall be
within the sole discretion of the  Administrator;  provided,  however,  that any
Incentive  Option  granted to a ten  percent  (10%) or less  stockholder  or any
Non-Qualified  Option shall, by its terms,  be exercised  within ten years after
the date the Option is granted  and any  Incentive  Option  granted to a greater
than ten percent (10%) stockholder shall, by its terms, be exercised within five
years after the date the Option is granted.

         (g) An Option and any Right related  thereto shall not be  transferable
by the Optionee other than by will, or by the laws of descent and  distribution.
An Option may be exercised during the Optionee's lifetime only by the Optionee.

         (h) The  Administrator  may impose such other or further  conditions on
any transaction under the 1996 Plan, including without limitation,  the grant or
award of any Option or the exercise or other disposition  thereof, as it, in its
discretion,  may deem necessary or advisable in order to exempt the  transaction
from Section 16(b) of the Exchange Act,  including without  limitation  thereto,
the approval or  ratification  of the transaction by shareholders or a six-month
restriction  on  disposition  of the Option or the Common  Stock  issuable  upon
exercise thereof.


                                   ARTICLE VI
                        EMPLOYMENT OR SERVICE OF OPTIONEE

         Section VI.1. If the employment or service of an Optionee is terminated
for cause,  the option rights of such Optionee,  both accrued and future,  under
any  then   outstanding   Non-Qualified  or  Incentive  Option  shall  terminate
immediately.  "Cause"  shall mean  incompetence  in the  performance  of duties,
disloyalty, dishonesty, theft, embezzlement, unauthorized disclosure of patents,
processes  or trade  secrets of the  Company,  individually  or as an  employee,
partner, associate,  officer or director of any organization.  The determination
of the  existence  and the proof of "cause"  shall be made by the  Administrator
and, subject to the review of any determination made by the Administrator,  such
determination shall be binding on the Optionee and the Company.

         Section  VI.2.  If  the  employment  or  service  of  the  Optionee  is
terminated  by either the  Optionee or the Company for any reason other than for
cause, death, or for disability, as defined in Section 22(e)(3) of the Code, the
option  rights of such  Optionee  under any then  outstanding  Non-Qualified  or
Incentive Option shall,  subject to the provisions of Section 5.1(h) hereof,  be
exercisable  by such Optionee at any time prior to the  expiration of the Option
or within three months after the date of such  termination,  whichever period of
time is  shorter,  but only to the extent of the accrued  right to exercise  the
Option at the date of such termination.

                                       iv

<PAGE>

         Section  VI.3.  In the case of an  Optionee  who becomes  disabled,  as
defined by Section  22(e)(3)  of the Code,  the option  rights of such  Optionee
under any then outstanding  Non-Qualified or Incentive Option shall,  subject to
the provisions of Section 5.1(h) hereof,  be exercisable by such Optionee at any
time prior to the  expiration of the Option or within one year after the date of
termination of employment or service due to disability, whichever period of time
is shorter,  but only to the extent of the accrued  right to exercise the Option
at the date of such termination.

         Section  VI.4.  In the event of the death of an  Optionee,  the  option
rights of such Optionee under any then  outstanding  Non-Qualified  or Incentive
Option shall be  exercisable  by the person or persons to whom these rights pass
by will or by the laws of  descent  and  distribution,  at any time prior to the
expiration  of the  Option  or  within  three  years  after  the date of  death,
whichever period of time is shorter, but only to the extent of the accrued right
to exercise the Option at the date of death.  If a person or estate acquires the
right to exercise a Non-Qualified or Incentive Option by bequest or inheritance,
the  Administrator may require  reasonable  evidence as to the ownership of such
Option,  and may require such consents and releases of taxing authorities as the
Administrator may deem advisable.

         Section VI.5. The  Administrator may also provide that an employee must
be  continuously  employed  by the  Company  for  such  period  of  time  as the
Administrator,  in its discretion,  deems advisable before the right to exercise
any portion of an Option granted to such employee will accrue,  and may also set
such other  targets,  restrictions  or other terms relating to the employment of
the Optionee which targets, restrictions, or terms must be fulfilled or complied
with,  as the case may be,  prior to the  exercise  of any  portion of an Option
granted to any employee.

         Section  VI.6.  Options  granted  under  this  1996  Plan  shall not be
affected by any change of duties or position,  so long as the Optionee continues
in the service of the Company.

         Section  VI.7.  Nothing  contained in this 1996 Plan,  or in any Option
granted  pursuant to this 1996 Plan,  shall  confer upon any  Optionee any right
with  respect  to  continuance  of  employment  or service  by the  Company  nor
interfere in any way with the right of the Company to terminate  the  Optionee's
employment or service or change the Optionee's compensation at any time.

                                   ARTICLE VII
                               PURCHASE OF SHARES

         Section VII.1.  Except as provided in this Article VII, an Option shall
be exercised by tender to the Company of the full  exercise  price of the shares
of Common Stock with respect to which the Option is exercised and written notice
of the  exercise.  The  right  to  purchase  shares  of  Common  Stock  shall be
cumulative  so that,  once the right to purchase  any shares of Common Stock has
accrued, such shares or any part thereof may be purchased at any time thereafter
until the  expiration or  termination  of the Option.  A partial  exercise of an
Option  shall not affect the right of the  Optionee to exercise  the Option from
time to time, in accordance  with this 1996 Plan, as to the remaining  number of
shares of Common Stock subject to the Option.  The purchase  price of the shares
shall be in United States  dollars,  payable in cash or by certified bank check.
Notwithstanding  the  foregoing,  in lieu of cash,  an  Optionee  may,  with the
approval of the  Administrator,  exercise  his or her Option by tendering to the
Company  shares of Common Stock of the Company owned by him or her and having an
aggregate fair market value at least equal to the full exercise price.  The fair
market value of any shares of Common Stock so surrendered shall be determined by
the Administrator in accordance with Section 5.1(b) hereof.

         Section  VII.2.  Except as provided in Article VI above,  an Option may
not be exercised unless the holder thereof is an officer, director, employee, or
consultant of the Company at the time of exercise.

         Section  VII.3.  No Optionee,  or Optionee's  executor,  administrator,
legatee, or distributee or other permitted  transferee,  shall be deemed to be a
holder of any  shares of  Common  Stock  subject  to an Option  for any  purpose
whatsoever  unless and until a stock certificate or certificates for such shares
are issued to such person under the terms of this 1996 Plan. No adjustment shall
be made for dividends (ordinary or extraordinary, whether in cash, securities or

                                       v

<PAGE>

other  property) or  distributions  or other rights for which the record date is
prior to the date such  stock  certificate  is  issued,  except as  provided  in
Article VIII hereof.

         Section VII.4.  If: (i) the listing,  registration or  qualification of
the Options issued  hereunder,  or of any  securities  issuable upon exercise of
such  Options  (the  "Subject  Securities")  upon  any  securities  exchange  or
quotation system or under federal or state law is necessary as a condition of or
in connection with the issuance or exercise of the Options,  or (ii) the consent
or approval of any  governmental  regulatory body is necessary as a condition of
or in connection with the issuance or exercise of the Options, the Company shall
not be obligated to deliver the certificates representing the Subject Securities
or to accept or to recognize an Option  exercise  unless and until such listing,
registration,  qualification,  consent or approval  shall have been  effected or
obtained.  The Company  will take  reasonable  action to so list,  register,  or
qualify the Options and the Subject Securities, or effect or obtain such consent
or approval, so as to allow for their issuance.

         Section VII.5.  An Optionee may be required to represent to the Company
as a condition  of his or her  exercise of Options  issued  under this 1996 Plan
that: (i) the Subject Securities acquired upon exercise of his or her Option are
being acquired by him or her for investment purposes only and not with a view to
distribution or resale,  unless counsel for the Company is then of the view that
such a representation  is not necessary and is not required under the Securities
Act of 1933, as amended (the "Securities Act"), or any other applicable statute,
law,  regulation or rule;  and (ii) that the Optionee  shall make no exercise or
disposition of an Option or of the Subject  Securities in  contravention  of the
Securities  Act,  the  Exchange  Act or the  rules and  regulations  thereunder.
Optionees may also be required to provide (as a condition  precedent to exercise
of an Option) such  documentation as may be reasonably  requested by the Company
to assure  compliance  with  applicable law and the terms and conditions of this
1996 Plan and the subject Option.

         Section  VII.6.  The  Administrator  may, in its  discretion,  grant in
connection with any Option, at any time prior to the exercise thereof, the right
(previously defined as an "SAR" or collectively, the "SARs") to surrender all or
part of the Option to the extent that such Option is exercisable  and receive in
exchange an amount  (payable in cash,  shares of Common Stock valued at the then
fair market value, or a combination  thereof as determined by the Administrator)
equal to the difference (the "Spread") between the then fair market value of the
shares of Common  Stock  issuable  upon the  exercise of the Option (or portions
thereof  surrendered)  and the option  price  payable  upon the  exercise of the
Option (or portions thereof surrendered). Such SARS may be included in an Option
only under the following conditions:  (a) the SARS will expire no later than the
expiration of the  underlying  Option;  (b) the SARS may be for no more than one
hundred percent (100%) of the Spread;  (c) the SARS are  transferable  only when
the underlying  Option is transferable  and under the same  conditions;  (d) the
SARS may be  exercised  only  when  the  underlying  Option  is  eligible  to be
exercised;  and (e) the SARS may be exercised  only when the Spread is positive,
i.e.,  when the market  price of the stock  subject to the  Option  exceeds  the
exercise price of the Option.

         Section VII.7. An Option may also be exercised by tender to the Company
of a written notice of exercise together with advice of the delivery of an order
to a broker to sell part or all of the  shares of Common  Stock  subject to such
exercise  notice  and an  irrevocable  order to such  broker to  deliver  to the
Company (or its transfer agent) sufficient proceeds from the sale of such shares
to pay the exercise  price and any  withholding  taxes.  All  documentation  and
procedures to be followed in connection with such a "cashless exercise" shall be
approved in advance by the Administrator.

                                  ARTICLE VIII
                    CHANGE IN NUMBER OF OUTSTANDING SHARES OF
                    STOCK, ADJUSTMENTS, REORGANIZATIONS, ETC.

         Section  VIII.1.  In the event  that the  outstanding  shares of Common
Stock of the Company are  hereafter  increased  or  decreased or changed into or
exchanged for a different number of shares or kind of shares or other securities
of the Company or of another  corporation by reason of  reorganization,  merger,
consolidation,  recapitalization,  reclassification, stock split, combination of
shares, or a dividend payable in capital stock,  appropriate adjustment shall be
made by the  Administrator  in the number and kind of shares for the purchase of
which Options may be granted under this 1996 Plan,  including the maximum number
that may be granted to any one person. In addition, the Administrator

                                       vi

<PAGE>

shall make appropriate  adjustments in the number and kind of shares as to which
outstanding Options, or portions thereof then unexercised, shall be exercisable,
to the end that the  Optionee's  proportionate  interest  shall be maintained as
before  the  occurrence  to the  unexercised  portion  of the  Option and with a
corresponding adjustment in the option price per share. Any such adjustment made
by the Administrator shall be conclusive.

         Section VIII.2. The grant of an Option pursuant to this 1996 Plan shall
not  affect in any way the right or power of the  Company  to make  adjustments,
reclassifications,  reorganizations  or  changes  of  its  capital  or  business
structure or to merge or to  consolidate  or to dissolve,  liquidate or sell, or
transfer all or any part of its business or assets.

         Section VIII.3.  Upon the dissolution or liquidation of the Company, or
upon a  reorganization,  merger or  consolidation  of the Company as a result of
which the outstanding  securities of the class then subject to Options hereunder
are changed  into or  exchanged  for cash or property or  securities  not of the
Company's issue, or upon a sale of substantially all the property of the Company
to an association, person, party, corporation,  partnership, or control group as
that term is construed  for purposes of the Exchange  Act,  this 1996 Plan shall
terminate,  and all  outstanding  Options  theretofore  granted  hereunder shall
terminate,  unless  provision  be  made  in  writing  in  connection  with  such
transaction  for the  continuance of this 1996 Plan and/or for the assumption of
Options  theretofore  granted,  or the  substitution for such Options of options
covering  the  stock of a  successor  employer  corporation,  or a  parent  or a
subsidiary  thereof,  with appropriate  adjustments as to the number and kind of
shares and prices, in which event this 1996 Plan and options theretofore granted
shall continue in the manner and under the terms so provided.  If this 1996 Plan
and unexercised Options shall terminate pursuant to the foregoing sentence,  all
persons owning any unexercised  portions of Options then outstanding  shall have
the right, at such time prior to the  consummation  of the  transaction  causing
such  termination as the Company shall  designate,  to exercise the  unexercised
portions of their Options,  including the portions  thereof which would, but for
this Section 8.3 not yet be exercisable.

                                   ARTICLE IX
                       DURATION, AMENDMENT AND TERMINATION

         Section  IX.1.  The Board of Directors may at any time  terminate  this
1996 Plan or make such  amendments  hereto as it shall deem advisable and in the
best interests of the Company, without action on the part of the stockholders of
the Company unless such approval is required pursuant to Section 422 of the Code
or the regulations thereunder or other federal or state law; provided,  however,
that  no such  termination  or  amendment  shall,  without  the  consent  of the
individual to whom any Option shall  theretofore  have been granted,  materially
adversely  affect or impair the  rights of such  individual  under such  Option.
Pursuant  to  Section  422(b) of the Code,  no  Incentive  Option may be granted
pursuant  to this  1996 Plan  after  ten  years  from the date this 1996 Plan is
adopted  or the date this  1996  Plan is  approved  by the  stockholders  of the
Company, whichever is earlier.

                                    ARTICLE X
                                  RESTRICTIONS

         Section X.1. Any Options and shares of Common Stock issued  pursuant to
this 1996 Plan shall be subject to such restrictions on transfer and limitations
as shall,  in the opinion of the  Administrator,  be  necessary  or advisable to
assure  compliance  with the laws,  rules and  regulations  of the United States
government or any state or jurisdiction thereof. In addition,  the Administrator
may in any Stock Option Certificate and Agreement impose such other restrictions
upon  the  disposition  or  exercise  of an  Option  or upon  the  sale or other
disposition of the shares of Common Stock  deliverable  upon exercise thereof as
the Administrator may, in its sole discretion,  determine. By accepting an award
pursuant  to this 1996  Plan,  each  Optionee  shall  thereby  agree to any such
restrictions.

         Section X.2. Any certificate  issued to evidence shares of Common Stock
issued  pursuant  to an Option  shall bear such  legends and  statements  as the
Committee, the Board of Directors or counsel to the Company shall deem advisable
to assure  compliance with the laws,  rules and regulations of the United States
government or any state or jurisdiction  thereof. No shares of Common Stock will
be delivered  pursuant to exercise of the Options  granted  under this 1996 Plan
until the Company has obtained such consents or approvals  from such  regulatory
bodies of the United

                                      vii

<PAGE>


States  government or any state or  jurisdiction  thereof as the Committee,  the
Board of Directors or counsel to the Company deems necessary or advisable.

                                   ARTICLE XI
                              FINANCIAL ASSISTANCE

         Section XI.1. The Company is vested with authority under this 1996 Plan
to assist any  employee to whom an Option is granted  hereunder  (including  any
officer or  director of the  Company or any of its  subsidiaries  who is also an
employee)  in the  payment of the  purchase  price  payable on  exercise of such
Option,  by lending the amount of such  purchase  price to such employee on such
terms and at such rates of interest  and upon such  security (or  unsecured)  as
shall have been authorized by or under authority of the Board of Directors.  Any
such assistance  shall comply with the  requirements of Regulation G promulgated
by the Board of the Federal  Reserve  System,  as amended from time to time, and
any other applicable law, rule or regulation.

                                   ARTICLE XII
                              APPLICATION OF FUNDS

         Section XII.1.  The proceeds  received by the Company from the issuance
and sale of Common Stock upon exercise of Options granted  pursuant to this 1996
Plan are to be  added  to the  general  funds  of the  Company  and used for its
corporate purposes as determined by the Board of Directors.

                                  ARTICLE XIII
                              EFFECTIVENESS OF PLAN

         Section XIII.1.  This 1996 Plan shall become effective upon adoption by
the Board of Directors,  and Options may be issued hereunder from and after that
date  subject to the  provisions  of Section  3.3 above.  This 1996 Plan must be
approved  by the  Company's  stockholders  in  accordance  with  the  applicable
provisions  (relating  to the  issuance of stock or  options)  of the  Company's
governing documents and state law or, if no such approval is prescribed therein,
by the affirmative vote of the holders of a majority of the votes cast at a duly
held stockholders  meeting at which a quorum  representing a majority of all the
Company's outstanding voting stock is present and voting (in person or by proxy)
or, without regard to any required time period for approval, by any other method
permitted  by Section 422 of the Code and the  regulations  thereunder.  If such
stockholder  approval is not  obtained  within one year of the  adoption of this
1996 Plan by the Board of  Directors  or within such other time period  required
under  Section 422 of the Code and the  regulations  thereunder,  this 1996 Plan
shall remain in force,  provided  however,  that all Options issued and issuable
hereunder shall automatically be deemed to be Non-Qualified Options.

         IN WITNESS  WHEREOF,  pursuant to the approval of this 1996 Plan by the
Board of Directors, this 1996 Plan is executed and adopted as of the 26th day of
August, 1996.

Columbia, Maryland 21046-1891

                  Re:      Registration Statement on Form S-8

Gentlemen:

                  We have  acted as  counsel  to Essex  Corporation,  a Virginia
corporation  (the   "Corporation"),   in  connection  with  the  filing  of  the
Registration  Statement on Form S-8 by the Corporation  under the Securities Act
of 1933, as amended (the "Registration Statement"), which Registration Statement
registers  the  distribution  of up to  900,000  shares of  common  stock of the
Corporation,  par value $0.10 per share ("Common Stock"),  reserved for issuance
to eligible  employees of the Corporation  pursuant to each of the Corporation's
1999,  1998 and 1996  Stock  Option  and Stock  Appreciation  Rights  Plans (the
"Plans").  In that capacity,  we have reviewed the Articles of Incorporation and
Bylaws of the Corporation,  both as amended to date, the Registration Statement,
the Plans, the originals or copies of corporate records reflecting the corporate
action taken by the Corporation in connection with the approval of the Plans and
amendments thereto and the issuance of the Common Stock under the Plans and such
other instruments as we have deemed necessary for the issuance of this opinion.

                  Based  upon  the  foregoing,  we are of the  opinion  that the
Common  Stock to be  offered  under the Plans  has been duly  authorized  by all
requisite  action on the part of the Corporation  and, when issued in accordance
with the terms and conditions of the Plans,  will be legally issued,  fully paid
and non-assessable.

                  We consent to the filing of this  opinion as an exhibit to the
Registration  Statement.  In giving  this  consent,  we do not admit that we are
within the  category  of persons  whose  consent is required by Section 7 of the
Securities Act of 1933, as amended.


                                  Very truly yours,

We consent to the incorporation by reference in this  Registration  Statement of
Essex  Corporation  on Form S-8 of our report dated March 16, 2000 on our audits
of the financial statements of Essex Corporation as of December 26, 1999 and for
