                                ESSEX CORPORATION

          NOTES TO INTERIM UNAUDITED CONSOLIDATED FINANCIAL INFORMATION

NOTE 1:  General


FISCAL YEAR AND PRESENTATION

These  statements  cover  Essex   Corporation  (the  "Company"),   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 and its wholly-owned subsidiary, Computer Science Innovations,
Inc. ("CSI"), which was acquired effective April 30, 2004. On June 25, 2004, the
Company  completed  the  acquisition  of  substantially  all  of the  assets  of
Performance  Group,  Inc.  ("PGI").  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. References to the quarter(ly) and six month periods represent the 13-week
and 26-week periods,  respectively,  ending on the date indicated.  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,   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  considered  necessary for a fair  presentation of such
information. The operating results for the twenty-six week period ended June 27,
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 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

                                       7


                                ESSEX CORPORATION

          NOTES TO INTERIM UNAUDITED CONSOLIDATED FINANCIAL INFORMATION

per common share  incorporates the incremental  shares issuable upon the assumed
exercise of stock options and  warrants.  As of June 27, 2004 and June 29, 2003,
the effect of the  incremental  shares from  options,  warrants  and  contingent
shares  (if  applicable)  of  111,100  and  2,368,700,  respectively,  have been
excluded  from  diluted  weighted  average  shares as the effect would have been
antidilutive or contingencies were not resolved.

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:

          NOTES TO INTERIM UNAUDITED CONSOLIDATED FINANCIAL INFORMATION

NOTE 5:  Amortization of Other Intangible Assets

In connection  with the March 1, 2003  acquisition of SDL, there was $431,000 of
intangible value assigned  primarily to contracts.  In connection with the April
30, 2004  acquisition of CSI, there was $724,000 of value assigned  primarily to
contracts. In connection with the June 25, 2004 acquisition of substantially all
of the assets from Performance Group, Inc., there was $70,000 of value assigned,
primarily to covenants not to compete.  (See Note 7.)  Amortization  of $127,000
and $162,000 was  recognized  in the quarter and six months ended June 27, 2004,
respectively.  Amortization  of $128,000  and  $174,000  was  recognized  in the
quarter and six month periods ended June 29, 2003, respectively.

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.  The evaluation of the  realizability  of 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 historical and projected  operating
performance.  The Company had a deferred income tax asset valuation allowance of
$3.5 million at December 28, 2003.

NOTE 7:  Acquisitions

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. The Company incurred another
$125,000 in related legal and accounting  fees. 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 closed this transaction effective April 30, 2004.

The following table  summarizes the estimated fair values of the assets acquired
and liabilities assumed at the date of acquisition.

          NOTES TO INTERIM UNAUDITED CONSOLIDATED FINANCIAL INFORMATION

The intangible assets of $724,000 are primarily assigned to contracts which have
an estimated overall  amortization life of less than one year. The allocation of
the purchase price is preliminary and subject to adjustment following completion
of the valuation process.

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.

With its acquisition of Computer  Science  Innovations,  Inc. in April 2004, the
Company now 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. With the acquisition of substantially all
of the assets of  Performance  Group,  Inc.  in June 2004,  the  Company now has
services  and  systems in the areas of  Geographic  Information  Systems  (GIS),
Imagery  Processing  and  Analysis,  Spatial  Data  Development,   Environmental
Consulting,  Visualization,  and IT Solutions for  government and private sector
clients.

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 six months ended June 27, 2004 and June 29,
2003,  revenues  derived from U.S.  Government  programs were $34.3 million,  or
98.5%,   and  $7.1  million,   or  98.6%,   of  the  Company's  total  revenues,
respectively.  The Company received a substantial amount of its intelligence and
defense community revenues for 2004 and 2003 from sole source contracts.

                                ESSEX CORPORATION

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,  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 half 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.  The
Company completed, effective April 30, 2004, the acquisition of Computer Science
Innovations,  Inc. ("CSI"),  which is headquartered in Melbourne,  Florida,  for
approximately $8.1 million in cash and incurred an additional  $125,000 in legal
and accounting fees. 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
completed,  effective June 25, 2004, the acquisition of substantially all of the
assets of Performance  Group, Inc. ("PGI") with main offices in  Fredericksburg,
Virginia  for  approximately  $5.85  million  in cash and  assumed  $231,000  in
liabilities.  The  Company  also  incurred  $125,000  in outside  expenses.  PGI
provides  services and systems in the areas of  Geographic  Information  Systems
(GIS), Imagery 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 in calendar year 2003.

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.  In the second  quarter of 2004,  in connection  with this
contract, the Company leased over 50,000 square feet of space. The lease extends
until May 2011 with an option  for early  termination.  The space  will  contain
significant  floor  space to  provide  highly  classified  work areas as well as
assembly, warehouse and regular office space. The Company expects to recover the
majority of the costs of this  facility  via direct or indirect  charges to this
and other contracts.

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.

                                       13

                                ESSEX CORPORATION

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,  as indicated  above,  we sold in fiscal 2003 the first 10
HYPERFINE WDM family  devices to our customers in the  intelligence  and defense
communities.  As  noted  previously,  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 selling our HYPERFINE WDM and other optical  technologies
in the  government  marketplace  and will  continue  to pursue such sales in the
commercial markets.

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

                                ESSEX CORPORATION

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. The Company had no inventory balance as of June 27, 2004.

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 $34.8 million and $7.1 million in the first six
months of fiscal 2004 and 2003, respectively.  Total revenues were $20.6 million
and $4.1 million in the second  quarters of fiscal 2004 and 2003,  respectively.
The key  factors  for the higher  revenue  were the  increased  activity  on the
October 2003 $57.0  million  multi-year  award and the January 2004 $4.5 million
two-year award for software and systems  engineering  and the delivery of custom
systems to national  priority  programs.  Revenues  from these two awards in the
first half of 2004 were $24.9  million and $2.1 million,  respectively.  Of this
total $27.0  million,  $12.0 million was for purchased  hardware.  Revenues from
these two awards in the second  quarter of 2004 were $15.6 million and $500,000,
respectively.  Of this total  $16.1  million,  $6.1  million  was for  purchased
hardware.  There was no comparable  purchased hardware revenue in the first half
of 2003.  The Company had $1.1  million in service and  products  revenue in the
second  quarter of 2004 for the 2 months of operations  from its  acquisition of
CSI.

COST OF GOODS SOLD AND SERVICES  PROVIDED  ("CGS").  Total CGS  increased  $24.3
million to $29.0  million for the first six months of 2004 from $4.7 million for
the comparable period in 2003. As a percentage of total revenues,  total CGS was
approximately  83.3% for the first half of 2004, compared to approximately 65.2%
for the comparable period in fiscal 2003. For services and products revenue, CGS
was 75.4% for the first  half of 2004 as  compared  to 65.2% for the  comparable
period in 2003.  The increase in CGS reflects  increased  volume and revenue for
the period.  The increase in CGS as a percentage of revenue  reflects the change
in the mix of work,  primarily  related to the two contracts  awarded in October
2003 and January 2004.  Specifically,  upon award and ramp up, a majority of the
revenues under those  contracts  relate to subcontracts  and purchased  hardware
which are lower margin. Over time, we anticipate a gradual shift of a portion of
this work to our staff.  For the second  quarter  of 2004,  total CGS  increased
$14.4  million to $17.0 million from $2.6 million for the  comparable  period of
2003. As a percentage of total revenues,  total CGS was approximately  82.7% for
the second  quarter of 2004 as  compared to 63.1% for the  comparable  period in
2003. For services and products revenue, CGS was 76.1% for the second quarter of
2004 as  compared  to 63.1% for the  comparable  period in 2003.  For  purchased
hardware  revenues,  CGS was 98.4% and 98.6% in the first six  months and second
quarter of 2004,  respectively,  and there were no  comparable  purchases in the
first six months and second quarter of 2003.  These second quarter  results also
reflect the higher volume and  increased  subcontractor  and purchased  hardware
components discussed above.

Overall  margins  increased  from the end of first quarter of 2004 to the end of
second  quarter  of 2004  from  15.8%  to 16.7%  due to a  change  in the mix of
products and services  provided with an increase in our higher  margin  services
revenue relative to our purchased hardware revenue.

SELLING,   GENERAL   AND   ADMINISTRATIVE   EXPENSES.   Selling,   general   and
administrative  expenses  (SG&A)  increased $2.5 million to $4.5 million for the
first six months of 2004 from $2.0  million for the  comparable  period in 2003.
For the second quarter of 2004, SG&A increased $1.5 million to $2.7 million from
$1.2 million for the  comparable  period in 2003.  SG&A has increased to support
the higher  volume of business  as well as  including  the SG&A of the  acquired
businesses. SG&A has decreased as a percentage of revenues.

RESEARCH AND  DEVELOPMENT  EXPENSES.  Research and  development  (R&D)  expenses
increased  $221,000  to  $447,000  in the first six months of 2004  compared  to
$226,000 in the  comparable  period in 2003. For the second quarter of 2004, R&D
increased  $213,000 to $307,000  compared to $94,000 in the comparable period in
2003.  The Company  incurred the majority of its  research  and  development  on
efforts related to optical communications  technology and had incurred R&D since
May 2004 in the newly-acquired CSI operation.

AMORTIZATION OF OTHER  INTANGIBLE  ASSETS.  During the first six months of 2004,
amortization  of other  intangible  assets  was  $162,000,  which was  primarily
related to the CSI acquisition.  There was $174,000 of amortization costs in the
comparable  period  in 2003  relating  to the SDL  acquisition.  For the  second
quarters of 2004 and 2003, amortization was $127,000 and $128,000, respectively.
The  amortization  of  other  intangibles  related  to the SDL  acquisition  was
substantially complete in the first quarter of 2004.

                                ESSEX CORPORATION

NET INTEREST INCOME (EXPENSE). Net interest income was $125,000 in the first six
months of 2004  compared to net  interest  expense of $43,000 in the  comparable
period in 2003. For the second quarter of 2004, net interest  income was $49,000
compared to net interest  expense of $28,000 in the  comparable  period in 2003.
The net interest income  reflects the temporary  investment of the proceeds from
the stock offering.

NET INCOME.  The  Company  recorded  net income of  $480,000  and $75,000 in the
second  quarters of 2004 and 2003,  respectively.  Net income was  $792,000  and
$54,000  in the first  six month  periods  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 six months 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 June 27,  2004,  the  Company  had  total  contract  backlog,  funded  and
unfunded,  of  approximately  $92.0 million as compared  with $112.8  million at
December  28,  2003.  Of these  amounts,  funded  backlog was $31.2  million and
unfunded  backlog was $60.8  million at June 27, 2004  compared to $15.0 million
and $97.8  million,  respectively,  at fiscal  year end  2003.  Of the  unfunded
backlog at June 27, 2004,  approximately  $18.4 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 June 27, 2004 also
includes  the  remaining  balance  of  approximately  $23.5  million  on our $30
million,  ten-year  contract  through  2011 to  provide  communications  systems
support to the  intelligence  community.  Unfunded backlog at June 27, 2004 also
includes  the  remaining  balance of  approximately  $14.8  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.

During the first six months of 2004,  net cash used in operating  activities was
$2.5  million.  Cash  provided  from  net  income  and  non  cash  depreciation,
amortization  and other charges of  approximately  $1.2 million was offset by an
increase  in  accounts  receivable  and  prepaids  net of the change in accounts
payable and accrued items of $3.7 million.  The increase in accounts  receivable
during  the first six months of 2004 was due to the  increase  in sales and does
not reflect any  significant  change in payment cycle.  Payments of $3.9 million
were received  within 9 days after the end of the second  quarter of 2004 on our
largest  program.  Also,  accounts  receivable at the end of the second  quarter
includes $1.5 million of receivables purchased from an acquisition.

During the first six months of 2004,  net cash used in investing  activities was
$14.7  million,  of which  $14.2  million  was for the  acquisitions  of CSI and
substantially  all of the assets of PGI. The Company also expended  $479,000 for
property,  equipment  and  leaseholds  improvements  to support our growing work
force. The Company's working capital at June 27, 2004 decreased to $22.8 million
from $33.0 million at fiscal year end 2003.  The decrease was primarily a result
of the acquisitions of CSI and assets of PGI for cash.

During the first six month period of fiscal 2004, net cash provided by financing
activities of $1.3 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 its existing 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
PREDICT.

ITEM 3.     QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company had no debt outstanding as of June 27, 2004.

ITEM 4.     CONTROLS AND PROCEDURES

Based on their most recent evaluation, Leonard E. Moodispaw, the Company's Chief
Executive Officer and Lisa G. Jacobson,  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 materially affected, or are reasonably likely to materially affect,
these  controls  subsequent  to the date of their  evaluation  and there were no
corrective  actions  with  regard  to  significant   deficiencies  and  material
weaknesses.
