         NOTES TO INTERIM CONSOLIDATED FINANCIAL INFORMATION (UNAUDITED)

NOTE 1:  GENERAL

Fiscal Year and Presentation

These consolidated  financial statements include the accounts of the Company and
its wholly-owned subsidiaries,  Computer Science Innovations, Inc. ("CSI") which
was  acquired on April 30, 2004 and The  Windermere  Group,  LLC  ("Windermere")
which was acquired on February 28, 2005. In addition,  these statements  reflect
the accounts and activities of Sensys  Development  Laboratories,  Inc.  ("SDL")
which was acquired March 1, 2003 and merged into the Company and the acquisition
of substantially  all of the assets of Performance  Group,  Inc. ("PGI") on June
25,  2004.  All  material  intercompany  transactions  have been  eliminated  in
consolidation. Certain amounts for 2004 have been reclassified to conform to the
2005 presentation.

Historically,  Essex  closed its fiscal year and its quarters on the last Sunday
of each period.  On December 22, 2004, the Board of Directors  approved changing
Essex's financial  reporting to calendar year end and end-of-the month quarterly
reporting.  This  change is not  significant  for  comparative  purposes  and is
effective for fiscal year end December 31, 2004 and all subsequent periods.

The  information  furnished in the  accompanying  Consolidated  Balance  Sheets,
Unaudited  Consolidated  Statements  of Operations  and  Unaudited  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  consisting of normal recurring accruals that, in the opinion of
management,   are  considered   necessary  for  a  fair   presentation  of  such
information. The operating results for the three months ended March 31, 2005 may
not be indicative of the results of operations for the year ending  December 31,
2005,  or any  future  period.  This  financial  information  should  be read in
conjunction with the Company's 2004 audited  consolidated  financial  statements
and footnotes  thereto,  included in the Annual Report on Form 10-K for the year
ended  December 31, 2004.  Significant  accounting  policies are detailed in our
Annual  Report on Form 10-K for the fiscal year ended  December 31, 2004.  For a
discussion of our Critical Accounting Policies,  refer to "Management Discussion
and Analysis of Financial Condition and Results of Operations" and the Company's
Annual Report on Form 10-K for the fiscal year ended December 31, 2004.

NOTE 2:  BASIC AND DILUTED EARNINGS PER SHARE

Basic earnings 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, warrants
and convertible debt. As of March 31, 2005 and March 28, 2004, the effect of the
incremental shares from options,  warrants and contingent shares (if applicable)
of 35,000 and 110,600  respectively,  have been excluded  from diluted  weighted
average shares as the effect would have been anti-dilutive.

         NOTES TO INTERIM CONSOLIDATED FINANCIAL INFORMATION (UNAUDITED)

NOTE 3:  COMMON STOCK

In December  2004,  the Company  completed  a follow-on  public  offering of 5.6
million shares of its common stock,  including  568,000 shares from the exercise
of the underwriter's  over-allotment  option,  and received a total net proceeds
from all shares issued of approximately $87.0 million.

The Company  completed a follow-on  public  offering in December 2003 and issued
4.0 million 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 March 1, 2003  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 three months 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 currently applies the intrinsic value method in accounting for stock
options  granted to employees and directors.  Under the intrinsic  value method,
compensation  costs is the  excess,  if any, of the quoted  market  price of the
stock at grant date or other  measurement  date over the amount an employee must
pay to acquire the stock.  If the Company had used the fair value based  method,
net  earnings  and  earnings  per share would have been reduced to the pro forma
amounts listed in the below table.

Intangible  assets  relate  primarily  to customer  relationships.  In addition,
intangibles   include   non-compete   agreements  and   intellectual   property.
Intangibles  are amortized over their  estimated life, not exceeding five years.
Total amortization through March 31, 2005 amounts to approximately $1.5 million.
During the first three months of 2005,  amortization of other intangible  assets
was $552,000 as compared to $35,000 in the comparable period in 2004.

NOTE 6:  INCOME TAXES

The Company is in a net operating  loss ("NOL")  carryforward  position for book
and tax purposes.

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.  Management  periodically  evaluates the valuation  allowance  recorded
against net operating loss carryforwards and other deferred tax assets to assess
whether  information  exists to warrant reversal based upon a variety of factors
for generating future taxable income, such as historical and projected operating
performance.  The Company had a deferred income tax asset valuation allowance of
$5.4 million at December 31, 2004.

NOTE 7:  ACQUISITIONS

On February 28, 2005, the Company  acquired 100% of the ownership and membership
interests of Windermere,  which was headquartered in Annapolis,  Maryland, for a
total initial purchase price of $72.0 million,  including the initial payment of
$69.4  million  and legal and other fees of

$2.6 million.  Also,  the purchase  agreement  includes  terms for an additional
purchase  payment in May 2006 of up to $30.0 million for an "earn-out"  based on
profitability  as specified in the  purchase  agreement.  The sellers used $25.3
million of the proceeds from the initial purchase payment to repay the principal
and accrued  interest due Essex under a promissory note and loan agreement dated
January 7, 2005.

Windermere provides engineering  services,  software development and information
technology  solutions to government  agencies,  the  intelligence  community and
commercial customers.  Windermere had revenues of $64.7 million,  including $2.5
million of revenue from  discontinued  operations,  for the calendar  year ended
December 31, 2004.

         NOTES TO INTERIM CONSOLIDATED FINANCIAL INFORMATION (UNAUDITED)


NOTE 8:  MAJOR CUSTOMERS

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 award.  For the first three  months of 2005 and 2004,  revenues
derived  from U.S.  Government  programs  were $24.0  million,  or 93% and $14.2
million, or 100%, of the Company's total revenues,  respectively.  For the first
three  months  of  2005,  revenue  from the top  three  customer  programs,  all
performed for the same U.S.  Government  customer,  were $13.8 million or 54% of
the Company's revenues.  For the first three months of 2004, $9.2 million or 64%
of revenues were derived from one U.S. Government customer on one program.

NOTE 9:           LINE OF CREDIT

Windermere has a $10.0 million revolving line of credit loan agreement with Bank
of America.  In connection with the acquisition,  Essex became a guarantor.  The
line of credit is secured  primarily by the accounts  receivable of  Windermere.
The line of  credit  expires  on May 31,  2005 and  will  not be  extended.  The
agreement  contains  certain  financial and other standard  covenants  regarding
restrictions  on payments of dividends and capital  expenditures.  In connection
with the acquisition, these covenants have essentially been waived on a one-time
basis through May 31, 2005.  Borrowings  under the line of credit incur interest
at a floating  rate above LIBOR and an unused fee of 25 basis  points.  In early
March  2005,  Essex paid down the line  which had a balance  of $7.9  million at
February 28, 2005, the acquisition date. There were no borrowings outstanding as
of March 31, 2005. Essex is currently  negotiating a line of credit that will be
available for operating or other corporate needs.

OVERVIEW

Essex provides  advanced  signal,  image, and information  processing  solutions
primarily for U.S. Government  intelligence and defense customers. We create our
solutions by combining our services and expertise with hardware,  software,  and
proprietary and patented technology to meet our customers' requirements.  During
the first quarter of 2005 we completed our acquisition of The Windermere  Group,
LLC and its  active  subsidiaries  ("Windermere")  which  was  headquartered  in
Annapolis Maryland.  The Windermere  acquisition adds breadth and depth to Essex
capabilities  and  intelligence  customer  set.  In  addition,  Windermere  adds
information  assurance and cybersecurity  solutions to the range of intelligence
technologies  offered by Essex.  Within the intelligence and defense communities
both Essex and Windermere  have  established  and maintained  long-standing  and
successful  customer  relationships.  We are  also  developing  next  generation
signal, image,  information processing and information assurance solutions under
classified U.S. Government research and development awards. We have been able to
develop our current  proprietary  technology  using a combination  of government
funding and our own internal  funding and we believe this combination will allow
us to continue  to enhance and expand our  technology  and  services  for future
market needs.

Most of our revenues are derived from awards with the U.S. Government,  where we
are either the prime  contractor or a subcontractor  depending on the award. For
the  first  three  months  of 2005  and  2004,  revenues  derived  from the U.S.
Government  programs were $24.0 million,  or 93%, and $14.2 million, or 100%, of
our total revenues, respectively.

On certain  projects,  our  customers  require us to  purchase  and  provide the
materials  (which may include  hardware,  software and firmware)  portion of the
total system solution,  which entails our purchasing  materials from third party
vendors and  reselling it to our  customers.  We show the revenue and costs from
purchased   materials   separately   since  this   revenue   generally   carries
significantly  lower  margins  than  our  products  and  services  revenue.  The
purchased materials revenue is highly variable from quarter to quarter.

Our most  significant  expenses  are cost of goods sold and  services  provided,
which  consist  primarily  of direct  labor  and  associated  costs for  program
personnel and direct expenses incurred

                                       12



                                ESSEX CORPORATION

to complete projects,  including the cost of materials and subcontract  efforts.
Our ability to accurately  predict  personnel  requirements,  salaries and other
costs, as well as to manage  personnel  levels and utilize our personnel  versus
subcontracting the work, can have a significant impact on our cost of goods sold
and services provided.  Utilizing our own employees to complete projects results
in higher gross margins as compared to our enlisting subcontracted employees for
the same work.  As a result,  we seek to maximize our internal  labor content on
our awards.  Selling,  general and administrative  expenses consist primarily of
costs  associated with our management,  facilities,  finance and  administrative
groups and business development expenses which include bid and proposal efforts.
We have revenue from some awards on which our U.S.  Government  customers pay us
to perform  research and  development  on their  behalf.  We also spend funds on
internal  research and development,  which are separately  classified as such in
the financial  statements.  We are in a net operating loss carryforward position
for federal income tax purposes and in most states in which we operate.

On April 30,  2004,  we acquired  100% of the common  stock of Computer  Science
Innovations,  Inc., or 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.  Cognitive
engines are software that includes  predictive  models and classifiers,  and our
applications include the areas of fraud and anomaly detection,  image and signal
recognition,  information integration, knowledge management, network information
assurance,  semantic  processing  and  waveform  analysis.  CSI had  revenue  of
approximately  $7.6  million in its fiscal year ended March 31,  2004,  the last
full year prior to acquisition.

On June 25, 2004,  we acquired  substantially  all of the assets of  Performance
Group,  Inc.,  or PGI,  with  main  offices  in  Fredericksburg,  Virginia,  for
approximately  $5.8  million in cash and  $362,000 in assumed  liabilities.  PGI
provides services and systems in the areas of geographic information systems, or
GIS, image  processing  and analysis,  spatial data  development,  environmental
consulting,  visualization,  and IT solutions to government  and private  sector
clients.  PGI had revenue of approximately  $4.5 million for calendar year ended
2003, the last full year prior to acquisition.

On February 28, 2005, we acquired 100% of the ownership and membership interests
of The Windermere Group, LLC and its active subsidiaries,  or Windermere,  which
was headquartered in Annapolis  Maryland,  for a total initial purchase price of
$72.0  million,  including  the initial  payment of $69.4  million and legal and
other fees of $2.6 million.  Also, the purchase  agreement includes terms for an
additional purchase payment in May 2006 of up to $30.0 million for an "earn-out"
based on  profitability  as  specified  in the  purchase  agreement.  Windermere
provides engineering services,  software development and information  technology
solutions to government  agencies,  the  intelligence  community and  commercial
customers.  Windermere had revenues of $64.7 million,  including $2.5 million of
revenue from discontinued  operations,  for the calendar year ended December 31,
2004, or, on a pro forma basis, approximately 47% of the combined Windermere and
Essex revenue for the calendar  year ended 2004.  Essex has  identified  certain
material  weaknesses  in the internal  control over  financial  reporting of its
newly  acquired  Windermere  subsidiary.  In light of  these  weaknesses,  Essex
performed  additional review procedures to assure that the financial  statements
in this first quarter 10-Q for 2005 are in accordance  with U.S.  GAAP.  Essex's
management is continuing to evaluate the internal controls of its newly acquired
subsidiary  and is  developing  corrective  action plans to address the material
internal control weaknesses identified to date.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The  preparation  of  financial  statements  requires us 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
ongoing basis, we re-evaluate our estimates,  including those related to revenue
recognition,  research and development,  intangible assets and contingencies. We
base our estimates on  historical  experience  and on various other  assumptions
that we believe are  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. Estimates are used
when  accounting  for  uncollectible   accounts  receivable,   depreciation  and
amortization,  intangible  assets,  goodwill,  and  employee  benefit  plans and
contingencies,  among  others.  Actual  results may differ from these  estimates
under  different  assumptions or conditions.  We believe the following  critical
accounting policies affect our more significant  judgments and estimates used in
the preparation of our financial statements.

REVENUE RECOGNITION

We enter into the following types of U.S. Government agreements:

o      TIME AND MATERIAL. On time and material agreements, revenue is recognized
       to the extent of billable rates multiplied by hours delivered, plus other
       direct costs.

o      COST PLUS FEE. We recognize  revenue on cost plus fee arrangements to the
       extent costs are incurred plus a proportionate  amount of fee earned.  We
       must  determine  that the costs incurred are proper and that the ultimate
       costs  incurred will not overrun the expected  funding on the project and
       still  deliver  the scope of work  proposed.  Even  though  cost plus fee
       arrangements  generally  do not require that we expend costs in excess of
       the award 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,  we must
       determine that the indirect costs are properly accounted and allocated in
       accordance with reasonable cost allocation methods.

o      FIXED PRICE. On fixed price agreements,  we 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 award for
       the required services or product to be delivered.

Award or  incentive  fees may be received in lieu of, or in addition  to,  other
fees on time and material or cost plus contracts.  Where award or incentive fees
are  applicable,  we record as  revenue an  estimate  of the  expected  award or
incentive fee proportionate to the work performed. Estimated fee is based on our
experience under the contract or similar contracts and on on-going communication
with the client regarding performance.

We use historical technical performance  experience where applicable to evaluate
progress on fixed  price and cost plus fee jobs.  We use  historical  government
audit  experience  in the  indirect  cost area to  evaluate  the  propriety  and
expected  recovery  of our  indirect  costs  on cost  plus fee  agreements.  The
following  table  sets  forth the  percentage  of  revenues  under  each type of
contract for the three months ended March 31, 2005 and March 28, 2004:

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


The  change  for the  respective  periods  is  principally  attributable  to the
contract mix of the revenue associated with the Windermere acquisition.

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 overhead costs.
However, no general and administrative  costs are included.  Equipment which has
alternative future uses is capitalized and charged to expense over its estimated
useful life.

GOODWILL AND OTHER INTANGIBLE ASSETS

Business  acquisitions  typically  result in the recording of goodwill and other
intangible assets, which affect the amount of future period amortization expense
and possible impairment expense that we will incur. We have adopted Statement of
Financial Accounting  Standards,  or SFAS, No. 142 which requires that we, 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.
Because of the integral technologies and operations of the acquisitions to date,
we have determined that Essex has only one  corporate-wide  reporting  entity to
which this test applies.

STOCK OPTIONS

In December  2004, the Financial  Accounting  Standards  Board  ("FASB")  issued
Statement  of Financial  Accounting  Standards  ("SFAS") No. 123R,  "Share-Based
Payment",  which is a revision of SFAS No. 123,  "Accounting for Stock Issued to
Employees".  SFAS No. 123R requires that all share-based  payments to employees,
including grants of employee stock options, be valued at fair value on the grant
date and be  expensed  over the  applicable  vesting  period.  SFAS No.  123R is
effective  for the Company on January 1, 2006.  The Company will  transition  to
SFAS No. 123R using the "modified prospective application".  Under the "modified

                                       15


                               ESSEX CORPORATION

prospective application", compensation costs will be recognized in the financial
statements  for all new  share-based  payments  granted  after  January 1, 2006.
Additionally,  the Company will recognize  compensation costs for the portion of
previously  granted awards for which the requisite service has not been rendered
("nonvested  awards")  that are  outstanding  as of  January  1,  2006  over the
remaining requisite service period of the awards. The compensation expense to be
recognized  for the  nonvested  awards  will be based  on the fair  value of the
awards.  We are  currently  evaluating  the effect that the adoption of SFAS No.
123R will have on our Financial  Position and Results of  Operations,  and it is
possible that our adoption of this  Standard may adversely  affect our operating
results in future  periods.  At March 31, 2005,  the total  valuation of options
issued  and  vesting  after  January  1, 2006 is  expected  to be  approximately
$75,000.

INCOME TAXES

Deferred income taxes are recorded under the asset and liability  method whereby
deferred  tax  assets  and   liabilities  are  recognized  for  the  future  tax
consequences, measured by enacted tax rates, attributable to differences between
the financial  statement carrying amounts of existing assets and liabilities and
their  respective  tax bases and  operating  loss  carryforwards.  The effect on
deferred tax assets and  liabilities  of a change in tax rates is  recognized in
income in the period the rate change becomes effective.  Management periodically
evaluates  the  valuation   allowance   recorded   against  net  operating  loss
carryforwards and other deferred tax assets to assess whether information exists
to warrant reversal.  At March 31, 2005, management has determined that reversal
of the existing  valuation  allowance is not  warranted at this time because the
Company  continues to  experience  significant  book tax  differences  which the
Company's  management believes should reduce taxable income  substantially below
income  reported  on  the  financial   statements.   Those  differences  include
amortization  of goodwill over fifteen years and the deduction  associated  with
the exercise of employee stock options.  Also,  while the Company  achieved both
book and taxable profit in 2004, it did not have  sufficient  future firm funded
sales backlog at March 31, 2005 to ensure  sufficient  future  taxable income to
realize the deferred tax asset.

revenue from the Windermere  acquisition and a full three months of revenue from
the  acquisitions  of CSI and PGI.  Windermere  had  revenues of $64.7  million,
including $2.5 million of revenue from discontinued operations, for the calendar
year preceding  acquisition while PGI had revenue of approximately  $4.5 million
for calendar year ended 2003, the last full year prior to  acquisition.  CSI had
revenue of  approximately  $7.6 million in its fiscal year ended March 31, 2004,
the last full  year  prior to  acquisition.  Other key  factors  for the  higher
revenue  were the  increased  activity on our $227.4  million  multi-year  award
(increased in December 2004 from the $57.1 million originally awarded in October
2003) for software and systems engineering and the delivery of custom systems to
national priority  programs.  Revenues from this award in the first three months
of 2005 and 2004 were $10.4  million  and $9.2  million,  respectively  of which
$739,000 and $5.0 million, respectively, was for purchased materials.

GROSS MARGIN The  improvement  in total gross margin results from improved gross
margin on both our services and products revenue and on our purchased  materials
revenue.  Services  and products  gross margin  increased to 29.3% for the first
three  months of 2005 from 25.8% for the first three  months of 2004 as a result
of a change in the mix of the work  performed,  particularly  under our  October
2003 award, moving from lower margin subcontract labor to higher margin internal
labor.  In  addition,  this margin  increased  as a result of higher  margins on
contracts

                                       17


                               ESSEX CORPORATION

obtained through  acquisitions  that occurred over the last year.  However,  the
gross margin on our Windermere acquisition is slightly below the pre-acquisition
Essex gross margin for the first three months of 2005,  principally because of a
significant  component of subcontractor  revenue on its largest  contract.  As a
result,  we expect a slight temporary decline in gross margin as the full impact
of  Windermere  occurs,  beginning  in the  second  quarter  of 2005,  and as it
continues its initial ramp up of that contract with  subcontractors.  Over time,
we expect to see a gradual  shift of work to our staff on our October 2003 award
and on  Windermere's  largest  contract,  with a resulting  improvement in gross
margin. The improvement in gross margin on purchased materials to 8.3% from 1.9%
resulted from a new short term contract  with a materials  component  that had a
higher margin along with higher margins for materials on acquired  contracts and
rate increases on other contracts.

SELLING,   GENERAL   AND   ADMINISTRATIVE   EXPENSES.   Selling,   general   and
administrative  expenses ("SG&A") increased $3.4 million to $5.2 million for the
first three months of 2005 from $1.8 million for the comparable  period in 2004.
SG&A has increased to support the higher volume of business as well as including
the SG&A of the  acquired  businesses.  SG&A as a  percentage  of  services  and
products  revenue was 22.2% of services and products revenue for the first three
months of 2005 and 2004. SG&A as a percentage of total revenue was 20.2% for the
first three months of 2005 compared to 12.9% for the first three months of 2004.
Approximately  42% of the  revenues  generated in the first three months of 2004
were low margin materials revenue which required little administrative support.

RESEARCH AND DEVELOPMENT  EXPENSES.  Research and development expenses increased
$346,000 to $487,000 in the first three  months of 2005  compared to $141,000 in
the  comparable  period in 2004.  We incurred  the  majority of our research and
development on efforts related to optical communications technology. In 2005, we
also  incurred  research and  development  costs  associated  with our cognitive
systems.

AMORTIZATION  OF OTHER  INTANGIBLE  ASSETS.  During the first three months ended
March 31, 2005, amortization of other intangible assets increased by $517,000 to
$552,000  compared to $35,000 in the  comparable  period in 2004.  This increase
primarily  related to the  Windermere,  PGI and CSI  acquisitions,  all of which
occurred subsequent to the first three months of 2004.

NET INTEREST INCOME (EXPENSE).  Net interest/dividend income was $732,000 in the
first three months of 2005 compared to $76,000 in the comparable period in 2004.
The net interest income  reflects the temporary  investment of the proceeds from
our 2004 stock offering, and also $285,000 from a $25 million loan to Windermere
prior to its purchase by Essex.

NET INCOME. We recorded net income of $1,536,000 and $312,000 in the first three
months  of  2005  and  2004,  respectively.  We  are  in a  net  operating  loss
carryforward  position for book and tax purposes.  We recognized a provision for
state income taxes of $20,000 in the first three months of 2005 for states where
our net operating loss is not available.

BACKLOG 

Our awards with the U.S. Government generally extend over multiple years. Funded
backlog generally consists of the sum of all award amounts for which funding has
been approved and awards  granted,  less the value of work performed  under such
awards.  Since the U.S.  Government  operates under annual  appropriations,  our
customers  typically fund awards on an

                                       18


                               ESSEX CORPORATION

incremental basis, generally for periods of one year or less. In many cases, our
awards include  unexercised  options.  Accordingly,  a significant amount of our
backlog is "unfunded." We include in unfunded  backlog the total value of signed
contracts,  less funding to date. Unfunded backlog includes awards options based
upon expected  performance  levels for those options.  Unfunded backlog does not
include any estimate of future  potential  delivery orders that might be awarded
under indefinite delivery indefinite quantity contracts.

As of March 31,  2005,  we had total  backlog,  funded and  unfunded,  of $408.1
million as compared  with  $102.0  million at March 28 2004.  Of these  amounts,
funded  backlog was $103.6  million and unfunded  backlog was $304.5  million at
March 31, 2005 compared to $31.3 million and $70.7 million,  at the three months
ended March 31, 2004.  Unfunded backlog at March 31, 2005 includes the remaining
balance of $153.2  million on our $227.4 million  multi-year  award in which the
ceiling was  significantly  increased  (from its original $57.1 million  October
2003 award) in December 2004 for software and systems engineering.  At March 31,
2004 unfunded  backlog on this contract was $24.8 million.  Unfunded  backlog at
March  31,  2005  also  includes  the  remaining  balance  of $80.7  million  on
Windermere's $105.1 million multi-year award for engineering  services which was
awarded in September  2004. Both  Windermere and Essex are  subcontractors  on a
single contract to provide  communication  systems  support to the  intelligence
community  through 2011. The total contract value of both subcontracts was $46.1
million.  The total unfunded backlog for both subcontracts at March 31, 2005 was
$18.6 million.  Unfunded backlog for the Essex  subcontract was $22.9 million at
March 31, 2004.

Our total backlog has increased  significantly  during the first three months of
2005 from the period ending December 31, 2004 due to the Windermere acquisition.

We expect 72.8% of our total backlog to be utilized after December 31, 2005.

FINANCIAL CONDITION - LIQUIDITY AND CAPITAL RESOURCES


Our primary liquidity and capital resource needs are to finance the costs of our
operations and to make capital  expenditures  and  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 at
least the next twelve months.

During the first three months of 2005, net cash used in operating activities was
$2.0  million.  Cash used in the first three months of 2005 was from an increase
of $4.5 million in accounts  receivable,  net of the change in accounts  payable
and  other  liabilities   offset  by  net  income  and  non-cash   depreciation,
amortization  and other charges of  approximately  $2.5 million.  An increase in
accounts  receivable  during the first three months of 2005 was primarily due to
the December 2004 expansion of the Company's $57.1 million October 2003 award to
a $227.4 million award which delayed  billings  during the first three months of
2005 due to operating and accounting  changes required under the modified award.
On April 1, 2005 we  received  a payment  under  this  award of $1.7  million of
which,  without the  expansion  award,  we would have  expected to have received
within the first three months of 2005.

During the first three months of 2005, net cash used in investing activities was
$73.2 million, of which $71.8 million,  net of cash acquired in the acquisition,
was for the  acquisition  of  Windermere.  We also  expended  $1.4  million  for
property,  equipment  and  leasehold  improvements  to support our growing  work
force.  Our working  capital at March 31, 2005  decreased to $38.5  million from
$108.4  million at fiscal year end 2004.  The decrease was primarily a result of
the acquisition of Windermere for cash.

During the first three months of 2005, net cash used in financing activities was
$8.0  million  which  primarily  represented  the cash pay down of the  acquired
Windermere line of credit to reduce interest expense.

The Company expects to satisfy its operating cash requirements for the remainder
of 2005 from its  projected  positive  operating  cash flows and  existing  cash
balance. To the extent that future  acquisitions,  capital  requirements,  or an
additional payment under the Windermere  purchase agreement requires cash beyond
our  expected  positive  cash flows and  existing  cash  balance,  we are in the
process of negotiating a bank line of credit.

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,  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 PREDICT.

ITEM 3.           QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company had no variable rate debt outstanding as of March 31, 2005.

Our exposure to market risk relates to changes in interest  rates on  short-term
investment of the remaining  proceeds of our stock  offerings.  Presently,  such
investments earn approximately 2.5%. Based upon our investments during the first
three months of 2005, a  hypothetical  1% increase or decrease in interest rates
would have  increased  or  decreased  income by $10,000  for every $1.0  million
invested and would have increased or decreased our annual cash flow and interest
income by a comparable amount.

ITEM 4.  CONTROLS AND PROCEDURES

On February 28, 2005, we acquired 100% of the ownership and membership interests
of Windermere for a total initial purchase price of $72.0 million, including the
initial  payment  of $69.4  million  and legal and other  fees of $2.6  million.
Windermere provides engineering  services,  software development and information
technology  solutions to government  agencies,  the  intelligence  community and
commercial customers.  Windermere had revenues of $64.7 million,  including $2.5
million of revenue from  discontinued  operations,  for the calendar  year ended
December 31, 2004, or, on a pro forma basis,  approximately  47% of the combined
Windermere and Essex revenue for the calendar year ended 2004.

Essex has identified  certain  material  weaknesses in the internal control over
financial  reporting of its newly acquired  Windermere  subsidiary.  In light of
these  weaknesses,  Essex performed  additional review procedures to assure that
the  financial  statements in this first quarter 10-Q for 2005 are in accordance
with U.S.  GAAP.  Essex's  management  is  continuing  to evaluate  the internal
controls of its newly acquired  subsidiary and is developing  corrective  action
plans to address the material internal control weaknesses identified to date.

In  connection  with the  preparation  of this  form  10-Q,  an  evaluation  was
performed under the supervision and with the participation of Essex's management
(including  the Chief  Executive  Officer  and Chief  Financial  Officer) of the
effectiveness of the design and operation of the Company's  disclosure  controls
and  procedures  (as defined in Exchange  Act Rules  13a-15e  under the Exchange
Act).  In  light  of  the  proximity  of  the  consummation  of  the  Windermere
acquisition  to the end of the first quarter for 2005 and  management's  ongoing
evaluation  and corrective  action with respect to the internal  controls of the
Windermere  subsidiary,  Essex's management has excluded the disclosure controls
and procedures of the Windermere subsidiary from its evaluation.  Subject to the
foregoing,  based on their  most  recent  evaluation,  Essex's  Chief  Executive
Officer and Chief  Financial  Officer believe  Essex's  disclosure  controls and
procedures  (as defined in Exchange Act Rules 13a-15e and 15d-15e) are effective
as of the end of the period covered by this Form 10-Q.
