                                ESSEX CORPORATION

          NOTES TO INTERIM UNAUDITED CONSOLIDATED FINANCIAL INFORMATION

NOTE 1:  General

FISCAL YEAR AND PRESENTATION

These  statements  cover Essex  Corporation  (the  "Company")  and its  formerly
wholly-owned subsidiary,  Sensys Development  Laboratories,  Inc. ("SDL"), which
was  acquired  effective  March 1, 2003 and merged  into the  Company  effective
December  30, 2003.  The Company is on a 52/53-week  fiscal year ending the last
Sunday in December.  Years 2004 and 2003 are 52-week fiscal years.  All material
intercompany  transactions  have been eliminated.  Certain amounts for 2003 have
been reclassified to conform to the 2004 presentation.

The information  furnished in the accompanying  Unaudited  Consolidated  Balance
Sheets,  Consolidated  Statements of Operations and  Consolidated  Statements of
Cash Flows have been prepared in accordance with accounting principles generally
accepted in the United States of America for interim financial  information.  In
the opinion of management,  such information contains all adjustments considered
necessary for a fair presentation of such information. The operating results for
the  thirteen  week period  ended March 28,  2004 may not be  indicative  of the
results of  operations  for the year ending  December  26,  2004,  or any future
period.  This  financial  information  should  be read in  conjunction  with the
Company's 2003 audited consolidated  financial statements and footnotes thereto,
included  in the  Annual  Report  on Form 10-K  filed  with the  Securities  and
Exchange Commission.

USE OF ESTIMATES

The  preparation of the  consolidated  financial  statements in conformity  with
accounting  principles  generally  accepted  in the  United  States  of  America
requires  management to make estimates and assumptions  that affect the reported
amounts  of assets and  liabilities  and  disclosure  of  contingent  assets and
liabilities at the date of the financial  statements and the reported amounts of
revenues and  expenses  during the  reporting  period.  Estimates  are used when
accounting for uncollectible  accounts  receivable,  inventory  obsolescence and
valuation,  depreciation and amortization,  intangible assets,  employee benefit
plans and  contingencies,  among others.  Actual results could differ from these
estimates.

RESEARCH AND DEVELOPMENT

Research and  development  costs are expensed as  incurred.  Such costs  include
direct labor and materials as well as a reasonable allocation of indirect costs.
However,  no general and  administrative  costs are  included  in  research  and
development.  Equipment  which has  alternative  future uses is capitalized  and
charged to expense over its estimated useful life.

NOTE 2:  Basic and Diluted Earnings (Loss) Per Share

Basic earnings  (loss) per common share are computed using the weighted  average
number of common shares  outstanding  during the period reduced by  contingently
returnable   shares.   Diluted  earnings  per  common  share   incorporates  the
incremental  shares  issuable  upon the assumed  exercise  of stock  options and
warrants. As of March 28, 2004 and March 30, 2003, the effect of the incremental
shares from options,  warrants and contingent  shares (if applicable) of 110,600
and

                                       7

                               ESSEX CORPORATION

4,170,105, respectively, have been excluded from diluted weighted average shares
as the effect would have been antidilutive.

NOTE 3:  Common Stock

The Company  completed a follow-on  public  offering in December 2003 and issued
4,000,000  shares of common  stock.  The Company  received net proceeds of $31.4
million. In January 2004, the underwriters exercised their over allotment option
and the Company  sold an  additional  150,000  common  shares and  received  net
proceeds of $1.2 million.

In connection with the acquisition of SDL, the Company had issued  approximately
422,000  common shares into escrow.  These shares were to be released to certain
SDL  shareholders or returned to Essex based upon certain  factors,  principally
the future  market price of the  Company's  stock.  During the first  quarter of
2004,  the 422,000  shares in escrow were  returned to the Company in accordance
with the terms of the purchase agreement.

NOTE 4:  Stock-Based Compensation

The Company  accounts for stock options granted to employees and directors using
the intrinsic value based method of accounting.  Under this method,  the Company
does not  recognize  compensation  expenses  for the stock  options  because the
exercise price is equal to the market price of the underlying  stock on the date
of the grant. If the Company had used the fair value based method of accounting,
net  earnings  and  earnings  per share would have been reduced to the pro forma
amounts listed in the table below.  The  Black-Scholes  option pricing model was
used to calculate the pro forma stock-based  compensation costs. For purposes of
the pro forma disclosures,  the assumed  compensation  expense is amortized over
the option's  vesting  periods.  The pro forma  information  is consistent  with
assumptions used in the year end  calculations.  Accordingly,  net income (loss)
and earnings (loss) per share would be as follows:



                                              Thirteen Week Periods Ended

NOTE 5:  Amortization of Other Intangible Assets

In connection  with the March 1, 2003  acquisition of SDL, there was $431,000 of
value  assigned  primarily to  contracts  backlog.  Amortization  of $46,000 was
recognized in March 2003;  $128,000 in the quarter ended June 2003;  $121,000 in
the quarter ended  September 28, 2003 and $86,000 in the quarter ended  December
28, 2003. Amortization of $35,000 was recognized in the first quarter of 2004.

NOTE 6:  Income Taxes

The Company is in a net operating loss (NOL) carryforward  position for book and
tax purposes. The Company had a deferred income tax asset valuation allowance of
$3.5  million and $4.3  million at  December  28, 2003 and  December  29,  2002,
respectively.  Income tax expense  reconciled  to the tax  computed at statutory
rates is as follows:



                                                     2004             2003

                                              ===============   ==============



The  evaluation  of the  realizability  of such  deferred  tax  assets in future
periods  is made  annually  at year end based  upon a  variety  of  factors  for
generating future taxable income,  such as intent and ability to sell assets and
historical and projected  operating  performance.  The Company has established a
valuation  reserve  for all of its  deferred  tax  assets.  Such tax  assets are
available to be recognized and benefit future periods.

NOTE 7:  Acquisition

In April  2004,  the  Company  agreed to  acquire  100% of the  common  stock of
Computer Science Innovations, Inc. ("CSI"), which is headquartered in Melbourne,
Florida, for approximately $8.1 million in cash. CSI has proprietary techniques,
algorithms  and tools that are used to build  custom  "cognitive  engines" for a
broad range of intelligence,  defense and commercial customers and applications.
CSI had revenue of approximately $7.5 million in its fiscal year ended March 31,
2004. The Company expects to close this transaction during the second quarter of
2004, subject to customary closing conditions.

OVERVIEW

Essex Corporation (the "Company")  provides advanced  optoelectronic  and signal
processing  services and products for U.S.  Government  intelligence and defense
customers  and  communications  customers  with  whom  we have  established  and
maintained  long-standing  and successful  relationships.  The Company  provides
optoelectronic  and signal  processing  services to classified  U.S.  Government
customers under next generation research and development contracts.  The Company
supports the intelligence  community's  mission critical voice and video systems
infrastructure.  The Company provides systems fabrication, software integration,
testing,  field deployment and other  engineering  services to highly classified
U.S.  Government  customers.  The  Company  builds  optical  communications  and
networking  system  elements  and  components,  as  well  as  signal  and  image
processing  software  products.  While the  Company  has  historically  sold our
products to the  intelligence  and  defense  markets,  we believe  our  existing
products and our patent  portfolio  position us well to benefit from spending on
next  generation  technology  that  decreases the costs and increases the speed,
performance and security of existing communications networks.

Most of the  Company's  revenues  are  derived  from  contracts  with  the  U.S.
Government, where the Company is either the prime contractor or a subcontractor,
depending on the  contract.  For the three months ended March 28, 2004 and March
30, 2003,  revenues derived from U.S. Government programs were $14.2 million, or
100%, and $2.9 million,  or 96%, of the Company's  revenues,  respectively.  The
Company received a substantial  amount of its intelligence and defense community
revenues for 2004 and 2003 from sole source contracts.

The Company's  most  significant  expense is its cost of goods sold and services
provided,  which  consists  primarily of direct labor and  associated  costs for
program personnel and direct expenses incurred to complete contracts,  including
the cost of materials  and  equipment  and  subcontract  efforts.  The Company's
ability to accurately predict personnel requirements,  salaries and other costs,
as well as to manage personnel levels and successfully  redeploy personnel,  can
have a  significant  impact  on its cost of goods  sold and  services  provided.
Selling,   general  and  administrative  expenses  consist  primarily  of  costs
associated with the Company's management,

                                       10


                               ESSEX CORPORATION

finance  and  administrative  groups and  business  development  expenses  which
include bid and proposal  efforts,  and  occupancy,  travel and other  corporate
costs.

STATUS

The Company has experienced  significant growth in its U.S.  Government business
and has been actively  pursuing  growth  strategies  from  internal  efforts and
external  merger sources.  These efforts have resulted in profitable  operations
for the first  three  months of 2004 and fiscal  2003.  The  Company  completed,
effective  March 1, 2003, the  acquisition of Sensys  Development  Laboratories,
Inc.  ("SDL"),  a  Maryland-based  provider of system and  software  engineering
support services.  This merger added over 25 highly skilled professionals to the
Company's staff and  approximately $6 million of annual revenue for 10 months in
2003.  In  April  2004,  the  Company  agreed,   subject  to  customary  closing
conditions, to acquire 100% of the common stock of Computer Science Innovations,
Inc. ("CSI"),  which is headquartered in Melbourne,  Florida,  for approximately
$8.1 million in cash. CSI has proprietary techniques,  algorithms and tools that
are used to build custom "cognitive  engines" for a broad range of intelligence,
defense  and  commercial   customers  and  applications.   CSI  had  revenue  of
approximately  $7.5 million in its fiscal year ended March 31, 2004. The Company
expects to close this transaction during the second quarter of 2004.

In October  2003,  the Company was awarded a new  defense-related  contract  for
approximately  $57  million  over 4 years (a 3 month base  period  plus 4 option
years).  This is a delivery order contract for software and systems  engineering
and the delivery of custom systems to national priority programs. The Company is
the prime contractor and there are numerous team members/subcontractors who will
work on this program.

The Company continues to patent,  develop and commercialize its key leading-edge
optical  technologies,  principally  the  fiberoptic  HYPERFINE  WDM devices and
wireless  optical   processor   enhanced   receiver   architecture   (OPERA(TM))
technology. The purpose of the HYPERFINE WDM device is to increase the number of
usable  communications  channels  within a single optical fiber.  The purpose of
OPERA(TM) is to increase capacity and improve voice and data quality of wireless
systems.

Prototypes of the HYPERFINE WDM technology are being demonstrated to prospective
strategic  partners  and  investors.  During the first nine months of 2003,  the
Company sold ten of its initial HYPERFINE WDM family devices  consisting of five
prototype  demultiplexers and five of the new flat-top HYPERFINE WDM devices for
use in building  advanced optical code division  multiple access (OCDMA) systems
for $457,000 to several  government and intermediate  customers.  The Company is
also  developing  applications  for using HYPERFINE WDM to achieve privacy in an
all optical  network.  The Company is  developing  simulations  of its OPERA(TM)
wireless  receiver device technology and is undertaking to determine the various
market  entry  points for such device  technology.  The Company is also  holding
discussions  with  various  established   entities  that  are  in  the  wireless
communications market in order to determine the best communications applications
of such technology.

The Company  was awarded a patent for its  HYPERFINE  WDM  technology  in August
2003. In light of the  continued  unfavorable  conditions in the  communications
markets,  the market for our optical  technologies and products has been slow in
developing;  however,  we sold in fiscal 2003 the first 10 HYPERFINE  WDM family
devices to our customers in the intelligence and defense

                                       11



                               ESSEX CORPORATION

communities.  As noted above, we are significantly expanding our U.S. Government
business  base.  The expansion is designed to take  advantage of our  government
contracting  experience  and technical  expertise  and the increased  government
contracting  activity in the defense,  intelligence and homeland security areas.
We are also pursuing sales of HYPERFINE WDM in communications  markets and other
optical technologies in the government marketplace.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The preparation of financial  statements  requires the Company to make estimates
and judgments that affect the reported amounts of assets, liabilities,  revenues
and expenses, and related disclosure of contingent assets and liabilities. On an
on-going basis, the Company re-evaluates its estimates,  including those related
to revenue recognition,  R&D,  inventories,  intangible assets, income taxes and
contingencies.  The Company bases its estimates on historical  experience and on
various  other  assumptions  that  are  believed  to  be  reasonable  under  the
circumstances,  the results of which form the basis for making  judgments  about
the carrying values of assets and liabilities that are not readily apparent from
other sources.  Actual results may differ from these  estimates  under different
assumptions  or  conditions.   The  Company  believes  the  following   critical
accounting policies affect its more significant  judgments and estimates used in
the preparation of its financial statements.

REVENUE RECOGNITION

The  Company  enters into three types of U.S.  Government  contracts:  cost plus
fixed fee, fixed price and time and material.  The Company recognizes revenue on
cost  plus  fixed  fee  contracts  to  the  extent  costs  are  incurred  plus a
proportionate  amount of fee earned.  The Company must  determine that the costs
incurred are proper and that the ultimate  costs  incurred  will not overrun the
expected  funding on the contract and still deliver the scope of work  proposed.
Even  though cost plus fixed fee  contracts  generally  do not require  that the
Company expend costs in excess of the contract value,  such  expenditures may be
required in order to achieve customer  satisfaction and receive additional work.
In  addition,  since the  reimbursable  costs  include  both direct and indirect
costs, the Company must determine that the indirect costs are properly accounted
for and allocated in accordance with government cost accounting requirements. On
fixed  price  service  contracts,  the  Company  must  determine  that the costs
incurred  provide a  proportionate  amount of  progress on the work and that the
ultimate  costs  incurred  will not overrun the funding on the  contract and the
required hours will be delivered.  On fixed price product orders, revenue is not
recorded  until the Company  determines  that the goods have been  delivered and
accepted by the customer. On time and material contracts,  revenue is recognized
to the extent of billable rates multiplied by hours delivered, plus other direct
costs.  This is generally  the most  straightforward  revenue  computation.  The
Company uses historical  technical  performance  experience  where applicable to
evaluate  progress on fixed price and cost plus fixed fee jobs. The Company uses
historical government audit experience in the indirect cost area to evaluate the
propriety  and expected  recovery of its  indirect  costs on cost plus fixed fee
contracts.

RESEARCH AND DEVELOPMENT

The Company has expended  significant  amounts for research and  development for
new products. In accordance with generally accepted accounting  principles,  the
Company expenses and does not capitalize and add to inventory such expenditures.
When product design and prototypes are finalized and product  marketability  and
viability  have  been  established,   expenditures  for

inventory are treated accordingly. There is a judgmental aspect to this decision
which  could  result  in  the   over-expensing   in  some  cases  or  the  early
capitalization in other cases of such expenditures.

GOODWILL AND OTHER INTANGIBLE ASSETS

The  Company's  business  acquisitions  typically  result in goodwill  and other
intangible assets, which affect the amount of future period amortization expense
and possible  impairment  expense  that the Company will incur.  The Company has
adopted Statement of Financial  Accounting  Standards ("SFAS") No. 142 "Goodwill
and Other  Intangible  Assets",  which  requires that the Company,  on an annual
basis, calculate the fair value of the reporting units that contain the goodwill
and compare that to the  carrying  value of the  reporting  unit to determine if
impairment   exists.   Impairment   testing   must  take  place  more  often  if
circumstances or events indicate a change in the impairment  status.  Management
judgment is required in calculating the fair value of the reporting units.

REVENUES.  Total  revenues  were  $14.2  million  and $3.0  million in the first
quarters of fiscal 2004 and 2003,  respectively.  The key factors for the higher
revenue were the increased  activity on the October 2003 $57 million  multi-year
award and the January 2004 $4.5 million  two-year award for

                                       13

                               ESSEX CORPORATION

software and systems  engineering and the delivery of custom systems to national
priority  programs.  Revenues from these two awards in the first quarter of 2004
were $9.2 million and $1.6 million,  respectively,  total $10.8 million of which
$6.0  million was for  purchased  hardware.  There was no  comparable  purchased
hardware  revenue in the first  quarter of 2003.  The  Company's  communications
services contracts  contributed $1.1 million of revenues in the first quarter of
2004 and $0.6 million of revenues for the same period in fiscal 2003.

COST OF GOODS SOLD AND SERVICES PROVIDED ("CGS").  Total CGS provided  increased
$10.0  million to $12.0  million for the first quarter of 2004 from $2.0 million
for the comparable period in 2003. As a percentage of total revenues,  total CGS
was approximately 84.2% for the first quarter of 2004, compared to approximately
68.8% for the  comparable  period in fiscal  2003.  For  services  and  products
revenue,  CGS was 74.2% for the first  quarter of 2004 as  compared to 68.0% for
the  comparable  period  in 2003.  In the  first  quarter  of 2004,  there was a
significant  increase in subcontractor  costs for the two large customer systems
programs. On these two contracts combined there were subcontractor costs of $3.6
million. For purchased hardware revenues,  CGS was 98.1% in the first quarter of
2004 and there were no comparable  purchases in the first  quarter of 2003.  The
Company receives a lower markup on subcontractors  work and purchased  hardware.
Overall, the higher volume during the first quarter of 2004 contributed a larger
amount of gross profit, though at lower gross profit percentages.

SELLING,   GENERAL   AND   ADMINISTRATIVE   EXPENSES.   Selling,   general   and
administrative  expenses  increased  $1.0  million to $1.8 million for the first
quarter  of 2004 from  $0.8  million  for the  comparable  period  in 2003.  The
increase  was  partially  due to  higher  management  and  related  costs in the
government  contracts  area  and  increased  business  development  as  well  as
continuing costs in the  optoelectronics  and communications new device business
areas.

RESEARCH AND DEVELOPMENT  EXPENSES.  Research and development expenses increased
$9,000 to  $141,000  in the first  quarter of 2004  compared  to $132,000 in the
comparable period in 2003. The Company incurred the majority of its research and
development on efforts related to optical communications technology.

AMORTIZATION  OF OTHER  INTANGIBLE  ASSETS.  During  the first  quarter of 2004,
amortization of other intangible assets was $35,000, all of which was related to
the SDL  acquisition.  There was $46,000  amortization  costs in the  comparable
period in 2003 relating to SDL. The amortization of other intangibles related to
this acquisition is substantially complete.

NET INTEREST  INCOME  (EXPENSE).  Net  interest  income was $76,000 in the first
quarter of 2004  compared to net interest  expense of $16,000 in the  comparable
period in 2003. The net interest income reflects the temporary investment of the
$32 million of proceeds from the stock offering.

NET INCOME  (LOSS).  The Company  recorded net income of $312,000 and a net loss
$20,000 in the first quarters of 2004 and 2003, respectively.  The Company is in
a net  operating  loss  carryforward  position  for  book and tax  purposes.  No
provision for or benefit from income taxes was  recognized in the first quarters
of 2004 or 2003 due to the net  operating  loss  carryforwards.  We adjusted our
income tax valuation reserves accordingly during these periods.

BACKLOG

As of March 28,  2004,  the  Company  had total  contract  backlog,  funded  and
unfunded,  of  approximately  $102.0  million as compared with $112.8 million at
December  28,  2003.  Of these  amounts,  funded  backlog was $31.3  million and
unfunded  backlog was $70.7  million at March 28, 2004 compared to $15.0 million
and $97.8  million,  respectively,  at fiscal  year end  2003.  Of the  unfunded
backlog at March 28, 2004,  approximately $18.5 million represents the remaining
balance  of a $25.0  million  U.S.  Government  Indefinite  Delivery  Indefinite
Quantity,  or IDIQ,  contract through May 2007 to provide  technology to enhance
Department of Defense radar programs. Unfunded backlog as of March 28, 2004 also
includes  the  remaining  balance  of  approximately  $22.9  million  on our $30
million,  ten-year  contract to provide  communications  systems  support to the
intelligence  community.  Unfunded  backlog at March 28, 2004 also  includes the
remaining balance of approximately $24.8 million on our $57.1 million multi-year
contract for software and systems  engineering that we received in October 2003.
Funded backlog generally consists of the sum of all contract amounts of work for
which  funding has been approved and  contracts  signed,  less the value of work
performed under such contracts.

FINANCIAL CONDITION - LIQUIDITY AND CAPITAL RESOURCES


Our primary liquidity and capital resource needs are to finance the costs of our
operations including research and development, to make capital expenditures, and
to finance acquisitions.  Based upon our current level of operations,  we expect
that our cash flow from  operations and amounts of cash on hand will be adequate
to meet our anticipated needs for the foreseeable future.

The  Company  evaluates  its  liquidity  position  using  various  factors.  The
following represents some of the more important factors:

During the first  quarter of 2004,  net cash used in  operating  activities  was
$3,394,000.   Cash  provided   from  net  income  and  non  cash   depreciation,
amortization  and other  charges  of  approximately  $474,000  was  offset by an
increase  in  accounts  receivable  net of the change in  accounts  payable  and
accrued  items of  $3,868,000.  The increase in accounts  receivable  during the
first  quarter of 2004 was due to the increase in sales and does not reflect any
change in  payment  cycle.  The  Company's  working  capital  at March 28,  2004
increased  to $34.6  million  from $33.0  million at fiscal  year end 2003.  The
increase was  primarily a result of the sale of common stock for $1.2 million in
January 2004.

During the first  quarter of 2004,  net cash used in  investing  activities  was
$110,000 for property and equipment to support our growing work force.

During the first  thirteen  week  period of fiscal  2004,  net cash  provided by
financing  activities of $1.2 million resulted primarily from the sale of common
stock and proceeds from exercises of stock options. (See Note 3 - Common Stock.)

The Company expects to satisfy its operating cash requirements for the remainder
of 2004 from existing cash flows or from its cash balance.

INFLATION

Because of the Company's  substantial  activities in  professional  services and
product  development,  the Company is more labor  intensive  than firms involved
primarily  in  industrial  activities.  To attract and maintain  higher  caliber
professional  staff,  the  Company  must  structure  its  compensation  programs
competitively. The wage demand effect of inflation is felt almost immediately in
the Company's  costs,  however,  the net effect during the periods  presented is
minimal.

The  inflation  rate in the United  States  generally  has little  impact on the
Company's  cost-reimbursable type contracts and other short-term contracts.  For
longer-term,  fixed-price  and time and  material  type  contracts,  the Company
endeavors  to protect its margins by including  cost  escalation  provisions  or
other specific inflation protective terms in these contracts.

THE PRECEDING  PARAGRAPHS  DISCUSSING THE COMPANY'S  FINANCIAL CONDITION CONTAIN
FORWARD-LOOKING  STATEMENTS. THE FACTORS AFFECTING THE ABILITY OF THE COMPANY TO
MEET ITS FUNDING REQUIREMENTS AND MANAGE ITS CASH RESOURCES INCLUDE, AMONG OTHER
THINGS,  THE  AMOUNT  AND  TIMING OF  PRODUCT  SALES,  INVENTORY  TURNOVER,  THE
MAGNITUDE  OF FIXED  COSTS,  SALES  GROWTH  AND THE  ABILITY  TO OBTAIN  WORKING
CAPITAL,  ALL OF WHICH  INVOLVE  RISKS AND  UNCERTAINTIES  THAT ARE DIFFICULT TO

ITEM 3.           QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company has no debt outstanding as of March 28, 2004.

ITEM 4.  CONTROLS AND PROCEDURES

Based on their most recent evaluation, Leonard E. Moodispaw, the Company's Chief
Executive  Officer and Joseph R.  Kurry,  Jr.,  the  Company's  Chief  Financial
Officer,  have concluded that the Company's  disclosure  controls and procedures
(as defined in Exchange Act Rules 13a-14 and 15d-14) as of the end of the period
covered by this report are effective to ensure that  information  required to be
disclosed by the Company in this report is accumulated  and  communicated to the
Company's  management,  including its principal  executive officer and principal
financial officer,  as appropriate,  to be recorded,  processed,  summarized and
reported  within the time  periods  specified  by the  Securities  and  Exchange
Commission's rules and forms.

There were no significant  changes in the Company's  internal  controls or other
factors that could significantly affect these controls subsequent to the date of
their evaluation and there were no corrective actions with regard to significant
deficiencies and material weaknesses.
