PART I

ITEM 1.    BUSINESS
-------    --------

         Engineered Support Systems, Inc. (ESSI) is a holding company for 14
wholly-owned operating subsidiaries. These subsidiaries are organized within
ESSI's two business segments: Support Systems and Support Services. The
Support Systems segment includes the operations of Systems & Electronics
Inc. (SEI), Keco Industries, Inc. (Keco), Engineered Air Systems, Inc.
(Engineered Air), Engineered Coil Company, d/b/a Marlo Coil (Marlo Coil),
Engineered Electric Company, d/b/a Fermont (Fermont), Universal Power
Systems, Inc. (UPSI), Engineered Environments, Inc. (EEi), Pivotal Power
Inc. (Pivotal Power), Prospective Computer Analysts Incorporated (PCA) and
Mobilized Systems, Inc. (Mobilized Systems). The Support Services segment
includes the operations of Technical and Management Services Corporation
(TAMSCO), Radian, Inc. (Radian), Spacelink International, LLC (Spacelink)
and ESSIbuy.com, Inc. (ESSIbuy). Substantially all revenues within these two
segments are directly or indirectly derived from contracts with the U.S.
Department of Defense (DoD) and certain foreign militaries.

         Engineered Air was incorporated under the laws of the State of
Missouri in December 1981 and acquired the assets of the Defense Systems
Division of Allis-Chalmers Corporation in March 1982. ESSI was incorporated
under the laws of the State of Missouri in December 1983, and exchanged all
of its outstanding common stock for two-thirds of the common stock of
Engineered Air held by ESSI's founders. ESSI purchased the remaining
one-third of the common stock of Engineered Air in January 1984. ESSI
effected its initial public offering in August 1985. In March 1993, ESSI
purchased all of the outstanding stock of Associated Products, Inc.
(subsequently changed to Engineered Specialty Plastics, Inc. (ESP)).
Effective February 1998, Engineered Coil Company acquired substantially all
of the net assets of Nuclear Cooling, Inc., d/b/a Marlo Coil. In June 1998,
ESSI acquired all of the outstanding common stock of Keco. In February 1999,
Engineered Electric Company acquired substantially all of the net assets of
the Fermont Division of Dynamics Corporation of America, d/b/a Fermont. In
September 1999, ESSI acquired all of the outstanding common stock of SEI. In
May 2002, ESSI acquired all the outstanding common stock of Radian. In June
2002, ESSI acquired all the outstanding stock of UPSI. In May 2003, ESSI
acquired all of the outstanding stock of TAMSCO. In September 2003, ESSI
acquired all of the outstanding stock of EEi. In December 2003, ESSI
acquired all of the outstanding stock of Pivotal Power. In January 2005,
ESSI acquired all of the outstanding stock of PCA. In February 2005, ESSI
acquired all the outstanding membership interests of Spacelink. In May 2005,
ESSI acquired all the outstanding equity of Mobilized Systems.

         On September 21, 2005, ESSI and DRS Technologies, Inc. (DRS)
entered into a definitive agreement which provides for the acquisition by
DRS of all the outstanding common stock of ESSI for approximately $1.9
billion, or $43.00 per share (subject to possible adjustment), through a
combination of cash and DRS common stock. Pending customary regulatory
approvals and other closing conditions, including approval by ESSI and DRS
shareholders, the transaction is expected to close on or about January 31,
2006.

PRODUCTS AND SERVICES

         As described above, ESSI's operations currently are organized into
two business segments: Support Systems and Support Services. The Support
Systems segment designs, engineers and manufactures integrated military
electronics and other military support equipment primarily for the DoD, as
well as related heat transfer and air handling equipment for domestic
commercial and industrial users. The Support Services segment provides
engineering services, logistics and training services, advanced technology
services, asset protection systems and services, telecommunication systems
integration and information technology services primarily for the DoD. The
Support Services segment also provides certain power generation and
distribution equipment and vehicle armor installation to the DoD.

         For financial information regarding ESSI's business segments, see
"Management Discussion and Analysis of Financial Condition and Results of
Operations," and Note L to the Consolidated Financial Statements for the
year ended October 31, 2005 included elsewhere within this Annual Report on
Form 10-K.

                                     3


ENGINEERING AND DESIGN

         As ESSI has grown both internally and through acquisition, it
significantly has increased its engineering capabilities. As of October 31,
2005, ESSI has 1,165 people engaged in engineering activities that encompass
advanced development, engineering research and development, product
improvement and evolution, new product development, productionization,
logistic and life-cycle support, product re-engineering and support
services. ESSI believes its depth of engineering capabilities allows it to
cover all phases of a project from conception to full-life cycle support.

         The majority of ESSI's development activities are conducted under,
and funded directly or indirectly through, DoD contracts in response to
designated performance specifications. ESSI's expenditures on internal
research and development (IRAD) were approximately $4.6 million, $4.3
million and $2.9 million for the years ended October 31, 2005, 2004 and
2003, respectively.

         ESSI's engineering expertise is complementary to the military
markets it serves, primarily the environmental control, power, electronics,
heavy mechanical and material handling, security, communications, service
and logistical support markets. ESSI has engineering capabilities in the
areas of system design and analysis, electronic signal processing, power
electronics, software, firmware, mechanical design, control,
electro-mechanical, electro-optical, electro-chemical, acoustics,
thermodynamics, fluid and air flow, fluid pumping, HVAC, liquid fuel
combustion, chemical and biological hardened environmental control,
filtration and decontamination, power system analysis, environmental control
system analysis, stress analysis, water treatment analysis, water
purification technology, radar, target acquisition systems, automatic test
equipment, communication system analysis and all the logistic support
disciplines to include reliability, maintainability, embedded diagnostics
and prognostics, training and the development of web-based interactive
electronic technical manuals. ESSI's subsidiaries within the Support
Services segment have engineering expertise in fields such as re-engineering
obsolete mechanical and electronic products, nano-hardened products,
security system design, fuel cells and super critical reformation. ESSI's
engineering expertise has significant overlap throughout its operating
subsidiaries, allowing it to leverage engineering personnel and
technologies, and to function as an integrated team.

         ESSI's design and development of new products is enhanced by a
number of computer-aided design and manufacturing (CAD/CAM) systems as well
as a number of automated system design and analysis tools. CAD/CAM tools are
used by both engineers and draftsmen to design and validate complex products
and component parts. ESSI utilizes both two- and three-dimensional CAD/CAM
tools, providing both design and production engineers an interactive
environment with which to view the final product and all the relevant
interfaces. These tools are compatible across all of ESSI's operating
subsidiaries, allowing for virtual design and development without regard to
geographical location. ESSI's engineering technologies and expertise provide
it with the ability to adapt its production processes to new product needs
on a timely basis. ESSI also has the capability to provide complete
technical data support for the products it manufactures to include
integrated logistics support, spare parts provisioning and preparation of
technical manuals.

         ESSI intends to leverage its engineering and design capabilities to
continue to develop and evolve differentiated products and services that
address both the current and future needs of the DoD for rapid deployment,
smaller, lighter and more efficient equipment, and for innovative,
value-added service offerings.

MARKETING AND BUSINESS DEVELOPMENT

         ESSI's business development efforts are undertaken at two
functional levels. ESSI's corporate operation focuses on long-term strategic
planning, policy development, best practice identification and
dissemination, and on major programs which require the bundling of products
and services across traditional subsidiary lines. In addition, ESSI's
corporate Washington D.C. operations interface with service staffs within
the Pentagon and liaisons with key


                                     4


Congressional delegations. At the subsidiary level, a sales force is engaged
to identify and pursue programs with specific customers in a variety of
markets. With increased emphasis on ESSI's vision for the future, efforts
have begun to strengthen the long-term strategic planning process.
Market-based peer groups enable experts throughout ESSI to share knowledge
and collectively recommend direction and strategy. These peer groups also
evaluate market intelligence, customer knowledge and core competencies to
refine ESSI's growth strategies.

         ESSI's Business Development Organization meets on a regular basis
to identify and disseminate best practices in the areas of proposal
development and market presence. The sales force shares customer and market
intelligence, identifies key opportunities and assesses campaign strategies.
ESSI gathers information from primary sources such as the DoD budget and its
supporting documents, and military requirements documents such as Initial
Capabilities Documents, along with direct interface with its customers. ESSI
analyzes this data and then determines whether or not to bid on specific
projects based upon determinations of potential profitability and the
likelihood of award.

PURCHASED COMPONENTS AND RAW MATERIALS

         ESSI's products require a wide variety of components and materials.
Although ESSI has multiple sources of supply for most of its material
requirements, sole-source vendors supply certain components, and ESSI's
ability to perform certain contracts depends on their performance. In the
past, these required raw materials and various purchased components
generally have been available in sufficient quantities.

GOVERNMENT CONTRACTING

         ESSI's government contracts are obtained through the DoD
procurement process as governed by the Federal Acquisition Regulations and
related regulations and agency supplements, and are typically fixed-price
contracts. This means that the price is agreed upon before the contract is
awarded and ESSI assumes complete responsibility for any difference between
estimated and actual costs. For the fiscal year ended October 31, 2005,
approximately 64% of ESSI's revenues were derived from fixed-price contracts.

         Under the Truth in Negotiations Act of 1962 (Negotiations Act), the
U.S. government has the right for three years after final payment on certain
negotiated contracts, subcontracts and modifications, to determine whether
ESSI furnished the U.S. government with complete, accurate and current cost
or pricing data as defined by the Negotiations Act. If ESSI fails to satisfy
this requirement, the U.S. government has the right to adjust a contract or
subcontract price by the amount of any overstatement as defined by the
Negotiations Act.

         U.S. government contracts permit the U.S. government to
unilaterally terminate these contracts at its convenience. In the event of
such termination, ESSI is entitled to reimbursement for certain expenditures
and overhead as provided for in applicable U.S. government procurement
regulations. Generally, this results in the contractor being reasonably
compensated for work actually done, but not for anticipated profits. The
U.S. government also may terminate contracts for cause if ESSI fails to
perform in strict accordance with contract terms. Termination of, or
elimination of appropriation for, a significant government contract could
have a material adverse effect on ESSI's business, financial condition and
results of operations in subsequent periods. Similarly, U.S. government
contracts typically permit the U.S. government to change, alter or modify
the contract at its discretion. If the U.S. government were to exercise this
right, ESSI could be entitled to reimbursement of all allowable and
allocable costs incurred in making the change plus a reasonable profit.

         For manufactured items, the U.S. government typically finances a
substantial portion of ESSI's contract costs through progress payments. In
each such case, ESSI receives progress payments in accordance with DoD
contract terms which provide progress payments at 75% to 90% of costs
incurred.


                                     5


INTELLECTUAL PROPERTY

         ESSI owns various patents and other forms of intellectual property.
From time to time, ESSI develops proprietary information and trade secrets
regarding the design and manufacture of various products. ESSI considers its
proprietary information and intellectual property to be valuable assets.
However, ESSI's business is not materially dependent on their protection.

COMPETITION

         The markets for all of ESSI's products and services are highly
competitive. In order to obtain U.S. government contracts, ESSI must comply
with detailed and complex procurement procedures adopted by the DoD pursuant
to regulations promulgated by the U.S. government. ESSI believes the
regulations and procurement procedures are adopted to promote competitive
bidding. In addition, ESSI competes with a large number of suppliers to
commercial and industrial air handling customers. In all phases of its
operations, ESSI competes in both performance and price with companies, some
of which are considerably larger, more diversified and have greater
financial resources than ESSI.

BACKLOG

         ESSI records its backlog as either funded or unfunded backlog.
ESSI's funded backlog was $689.8 million and $588.1 million as of October
31, 2005 and 2004, respectively. ESSI's funded backlog is subject to
fluctuations and is not necessarily indicative of future revenues. Funded
backlog represents products or services that the customer has committed by
contract to purchase from ESSI. Unfunded backlog includes products or
services that the customer has the option to purchase under contract with
ESSI, including, with respect to contracts which include a maximum amount
purchasable by the customer thereunder, such maximum amount, and with
respect to contracts without a specified maximum amount, ESSI's estimate of
the amount it expects the customer to purchase using the Best Estimated
Quantity (BEQ) as a guide where a BEQ is specified. There are no commitments
by the customer to purchase products or services included in unfunded
backlog and there can be no assurance that any or all amounts included
therein will generate revenue for ESSI. Moreover, cancellations of purchase
orders or reductions of product quantities or levels of service to be
provided in existing contracts could substantially reduce ESSI's funded
backlog and, consequently, future net revenues. Failure of ESSI to replace
canceled or reduced backlog, whether funded or unfunded, could have a
material adverse effect on ESSI's business, financial condition and results
of operations in subsequent periods.

         The following table summarizes funded and unfunded defense backlog
(in millions) as of the indicated dates:

EMPLOYEES

         As of October 31, 2005, ESSI employed 3,673 persons, of which 1,196
were engaged in manufacturing activities, 1,165 in engineering activities
and 1,312 in services activities, office administration and management
functions. District No. 9 of the International Association of Machinists and
Aerospace Workers (AFL-CIO) represents 287 employees under a collective
bargaining agreement, which expires March 21, 2008.

FILING OF PERIODIC REPORTS

         ESSI regularly files periodic reports with the Securities and
Exchange Commission (SEC), including annual reports on Form 10-K and
quarterly reports on Form 10-Q, as well as, from time to time, current
reports on Form 8-K and amendments to those reports. These filings are
available free of charge on ESSI's website at www.engineeredsupport.com, as
soon as reasonably practicable after their electronic filing with the SEC.


ITEM 1A    RISK FACTORS
-------    ------------

         In addition to historical information, this Annual Report on Form
10-K contains or may contain certain forward-looking statements, within the
safe harbor provisions of the Private Securities Litigation Reform Act of
1995. Generally, the words "will," "may," "should," "continue," "believes,"
"expects," "intends," "anticipates," "estimates" or similar expressions
identify forward-looking statements, These forward-looking statements
involve certain risks and uncertainties. Factors that could cause actual
results to differ materially from those contemplated by the forward-looking
statements include, among others, the risks and uncertainties identified
below.

         THE OBLIGATIONS OF ESSI AND DRS TO COMPLETE THE PROPOSED MERGER ARE
SUBJECT TO THE SATISFACTION OR WAIVER OF CERTAIN CONDITIONS. THE FAILURE TO
SATISFY THESE CONDITIONS COULD RESULT IN TERMINATION OF THE MERGER
AGREEMENT, WHICH WOULD HAVE A MATERIAL ADVERSE EFFECT ON ESSI.

         A number of conditions must be satisfied before the proposed merger
between ESSI and DRS will be completed. These include among others:

     o   the receipt of the approval of the issuance of shares of DRS
         common stock in the merger by DRS stockholders and the approval of
         the merger agreement and the transactions contemplated by the
         merger agreement by ESSI shareholders;

     o   the absence of any legal restraints or prohibitions preventing the
         completion of the merger, or making such completion illegal;

     o   the receipt of all governmental and regulatory authorizations,
         consents, waivers, orders, approvals, or declarations required to
         consummate the merger, except as would not be reasonably expected
         to result in a material adverse effect on ESSI;

                                     7


     o   the representations and warranties of each party contained in the
         merger agreement being true and correct in all material respects;

     o   each party must have performed, in all material respects, all of
         its obligations under the merger agreement at or prior to the
         effective time of the merger agreement; and

     o   the absence of events or developments since the date of the merger
         agreement that would reasonably be expected to have a material
         adverse effect with respect to either party.

         ESSI can give no assurance that all of the conditions to the merger
will be either satisfied or waived or that the merger will occur. The failure
to satisfy these conditions could result in termination of the merger
agreement, which would have a material adverse effect on ESSI. The proposed
merger between DRS and ESSI is discussed in Note P to the Consolidated
Financial Statements included elsewhere in this Annual Report on Form 10-K.

         THE MERGER AGREEMENT MAY BE TERMINATED PRIOR TO COMPLETION OF THE
MERGER, WHICH WOULD HAVE A MATERIAL ADVERSE EFFECT ON ESSI.

         DRS and ESSI mutually may agree in writing, at any time before the
effective time of the merger, to terminate the merger agreement. Also,
either DRS or ESSI may terminate the merger agreement in a number of
circumstances, including if:

     o   the merger is not consummated by June 30, 2006 through no fault
         of the party seeking to terminate the merger agreement;

     o   there is a final, non-appealable injunction, judgment or other
         order, or law which prohibits the merger;

     o   the ESSI board of directors authorizes ESSI to enter into an
         agreement with respect to a superior proposal;

     o   ESSI shareholders fail to approve the merger agreement and the
         transactions contemplated by the merger agreement at the ESSI
         special meeting or at an adjournment of that meeting;

     o   DRS stockholders fail to approve the issuance of shares of DRS
         common stock in the merger at the DRS special meeting or at an
         adjournment of that meeting; or

     o   the party seeking termination is not in material breach of the
         merger agreement and the other party has materially breached a
         representation, warranty, covenant or agreement of that party
         contained in the merger agreement and such breach has not been
         cured within 15 days of notice of the breach.

         ESSI may terminate the merger agreement to accept an acquisition
proposal that is more favorable to ESSI and ESSI's shareholders from a
financial point of view than the proposed merger with DRS. ESSI must pay DRS
a termination fee of $60.0 million, plus up to $10.0 million in costs and
expenses of DRS in connection with the transactions contemplated by the
merger agreement, if the merger agreement is terminated due to ESSI's board
of directors authorizing ESSI to enter into an acquisition agreement with a
third party or if DRS terminates the merger agreement due to ESSI's board of
directors withdrawing its approval or recommendation of the proposed merger,
modifying its recommendation of the merger agreement in a manner adverse to
DRS or failing to recommend against any tender or exchange offer that
constitutes an alternative proposal. ESSI also must pay these fees and
expenses if ESSI or DRS terminates the merger agreement because the merger
has not been completed by the outside date or ESSI shareholders fail to
approve the merger agreement, an alternative proposal with respect to ESSI
shall have been publicly announced prior to such termination and ESSI enters
into or completes any merger or extraordinary transaction within twelve
months of the termination.

        DRS may terminate the merger agreement if the financing contemplated
by the merger agreement is not available on substantially the terms and
conditions identified in DRS's financing commitment letter, or on other

                                     8


terms or pursuant to other financing arrangements reasonably acceptable to
DRS, but DRS will not have the right to terminate for this reason if its
failure to fulfill its obligations to obtain financing is the cause of the
failure of financing to become available. ESSI may terminate the merger
agreement if DRS's financing contemplated in the merger agreement is not
available and DRS fails to enter into a substitute commitment letter or
alternate arrangements with other financing sources within 20 business days
of advising ESSI of the unavailability of such financing or substitute
financing. Under the merger agreement, DRS must pay ESSI $20.0 million in
liquidated damages upon such termination by DRS or ESSI.

         ESSI can give no assurance that the merger agreement will not be
terminated prior to completion of the merger or that the merger will occur.
Termination of the merger agreement, other than in respect of a superior
transaction that actually closes, would have a material adverse effect on
ESSI operations.

         DRS MAY NOT BE ABLE TO OBTAIN FINANCING TO PAY THE CASH PORTION OF
THE MERGER CONSIDERATION.

         In addition to the issuance of common stock, DRS intends to finance
the merger using a portion of available cash on hand, borrowings provided
for under the commitment letter issued by Bear, Stearns & Co. Inc. and
its affiliates (Bear Stearns) and Wachovia Capital Markets, LLC and its
affiliates (Wachovia) for a $706.9 million senior secured credit facility
consisting of a $356.9 million seven-year term loan and a $350.0 million
six-year revolving credit facility and through the issuance of a combination
of senior fixed-rate notes, senior floating-rate notes, senior subordinated
notes and/or convertible notes in an aggregate principal amount of $950.0
million. DRS has entered into a commitment with Bear Stearns and Wachovia
for the term loan and revolving credit facility. DRS also has entered into a
separate commitment letter with each of Bear Stearns and Wachovia for up to
a $950.0 million interim credit facility, if the placement of the permanent
debt financing cannot be consummated by the effective time of the merger.
Each of the commitment letters and the availability of the term loan,
revolving credit facility and interim facility, if necessary, is subject to
certain conditions precedent, including, among other things, that there be
no material adverse effect on ESSI. Therefore, ESSI can give no assurance
that the financing pursuant to the commitment letters will be available.
DRS's proposed offerings of notes pursuant to the permanent debt financing
is subject to market and other customary conditions, including, but not
limited to, general global and U.S. economic conditions, the market for
similar securities, and delivery of customary documents, officer
certifications and representations prior to, or at the time of, the closing
of the notes offering. There can be no assurance that DRS will be able to
complete the notes offering or enter into the term loan, the revolving
credit facility or the interim facility, if necessary, on commercially
reasonable terms, or at all.

         As of September 30, 2005, DRS's cash and cash equivalents were
approximately $257.3 million. DRS will not be able to complete the merger if
it is unable to obtain financing. DRS may terminate the merger agreement if
funding to consummate the merger pursuant to financing arrangements on
substantially the terms expected or other terms reasonably acceptable to DRS
shall not have become available. However, DRS will not have this termination
right if the failure to fulfill its obligations under the merger agreement
to obtain such financing is the cause of such financing not becoming
available. ESSI may terminate the merger agreement if DRS's financing
contemplated in the merger agreement is not available and DRS fails to
obtain substitute financing within 20 business days of advising ESSI of the
unavailability of such financing or substitute financing. Under certain
circumstances pursuant to the merger agreement, DRS must pay ESSI $20.0
million in liquidated damages upon such termination by DRS or ESSI.

         ESSI CURRENTLY IS SUBJECT TO AN SEC INVESTIGATION THAT COULD
REQUIRE SIGNIFICANT MANAGEMENT ATTENTION AND LEGAL RESOURCES AND COULD HAVE
A MATERIAL ADVERSE EFFECT ON ESSI OR THE COMBINED COMPANY.

         In December 2004, ESSI was notified by the Enforcement Division of
the SEC of the issuance of a formal order directing a private investigation
captioned In the Matter of Engineered Support Systems, Inc. and in September
2005, ESSI received notice that the SEC staff had expanded the scope of its
investigation. The investigation is discussed in greater detail under "Item
3--Legal Proceedings" of this Annual Report on Form 10-K. In connection with
the investigation, ESSI and certain of its directors and officers have
received subpoenas and provided information and testimony to the SEC and one
former director and officer who currently is a consultant has received a
so-called Wells notice. ESSI continues to furnish information required by
the SEC and otherwise to cooperate in connection with the

                                     9



investigation. ESSI is unable to determine at this time the impact, if any,
which the investigation could have on ESSI or the combined company following
ESSI's proposed merger with DRS as discussed in Note P to the Consolidated
Financial Statements included elsewhere in this Annual Report on Form 10-K.
If ESSI is unable to resolve the SEC investigation before completion of the
merger, it could require significant management attention and legal
resources and could have a material adverse effect on the combined company.

         THE VALUE OF THE STOCK COMPONENT OF THE MERGER CONSIDERATION COULD
VARY BASED UPON THE PRICE OF DRS COMMON STOCK.


         The merger consideration to be received by ESSI's shareholders in
exchange for each share of ESSI common stock includes $30.10 in cash and a
fraction of a share of DRS common stock to be determined based upon the
average closing sale price of DRS common stock for the ten consecutive
trading day period ending with the second complete trading day before the
closing of the merger. The merger agreement provides that such fraction will
be fixed at 0.2255 if the average price is $57.20 or greater and 0.2756 if
the average price is $46.80 or less. If such average price is less than
$57.20 and greater than $46.80, such fraction will be equal to $12.90
divided by the average price. If the average price is between $57.20 and
$46.80 per share, the total consideration per share of ESSI common stock as
of the date will be valued at $43.00; if the average price is less than
$46.80, the value of the per-share consideration will be less than $43.00,
and if the average price is greater than $57.20, the value of the
consideration per share of ESSI common stock will be greater than $43.00.
Accordingly, ESSI shareholders will not know the value of the stock
component of the merger consideration until after the closing date.

         THE REVENUES OF THE COMBINED COMPANY DEPEND ON DRS'S AND ESSI'S
ABILITY TO MAINTAIN LEVELS OF GOVERNMENT BUSINESS. THE LOSS OF CONTRACTS
WITH DOMESTIC AND NON-U.S. GOVERNMENT AGENCIES COULD ADVERSELY AFFECT THE
COMBINED COMPANY'S REVENUES.

         Both DRS and ESSI derive the substantial majority of their revenues
from contracts or subcontracts with domestic and non-U.S. government
agencies. A significant reduction in the purchase of products by these
agencies would have a material adverse effect on the businesses of DRS and
ESSI. For fiscal years ended October 31, 2005, 2004 and 2003, approximately
96%, 94% and 95%, respectively, of ESSI's revenues were derived directly or
indirectly from defense industry contracts with the U.S. government and its
agencies. In addition, in each of the fiscal years ended October 31, 2005,
2004 and 2003, approximately 3% of ESSI's revenues were derived directly or
indirectly from sales to foreign governments. Additionally, for fiscal years
ended March 31, 2005, 2004 and 2003, approximately 84%, 85% and 81%,
respectively, of DRS's revenues were derived directly or indirectly from
defense-industry contracts with the U.S. government and its agencies. In
addition, in each of the fiscal years ended March 31, 2005, 2004 and 2003,
less than 14% of DRS's revenues were derived directly or indirectly from
sales to foreign governments. Therefore, the development of the combined
company's business in the future will depend upon the continued willingness
of the U.S. government and its prime contractors to commit substantial
resources to defense programs and, in particular, upon the continued
purchase of ESSI's and DRS's products and other products which incorporate
their respective products, by the U.S. government. In particular, the
current funding demands on the U.S. government combined with a potential
reduction of forces in Iraq, may lead to lower levels of government defense
spending.

         The risk that governmental purchases of products may decline stems
from the nature of ESSI's and DRS's business with the U.S. government, in
which the U.S. government may:

     o   terminate contracts at its convenience;

     o   terminate, reduce or modify contracts or subcontracts if its
         requirements or budgetary constraints change;

     o   cancel multi-year contracts and related orders if funds become
         unavailable;

     o   shift its spending priorities;


                                     10


     o   adjust contract costs and fees on the basis of audits done by its
         agencies; and

     o   inquire about and investigate business practices and audit
         compliance with applicable rules and regulations.

         In addition, as defense businesses, DRS and ESSI are subject to the
following risks in connection with government contracts:

     o   the frequent need to bid on programs prior to completing the
         necessary design, which may result in unforeseen technological
         difficulties and/or cost overruns;

     o   the difficulty in forecasting long-term costs and schedules and
         the potential obsolescence of products related to long-term
         fixed-price contracts;

     o   the risk of fluctuations or a decline in government expenditures
         due to any changes in the DoD budget or appropriation of funds;

     o   when DRS or ESSI acts as a subcontractor, the failure or inability
         of the primary contractor to perform its prime contract may result
         in an inability to obtain payment of fees and contract costs;

     o   restriction or potential prohibition on the export of products
         based on licensing requirements; and

     o   government contract wins can be contested by other contractors.

         THE PRICE OF DRS COMMON STOCK MAY BE AFFECTED BY FACTORS DIFFERENT
FROM THOSE AFFECTING THE PRICE OF ESSI COMMON STOCK.

         Holders of ESSI common stock will be entitled to receive cash and
DRS common stock in the merger and thus will become holders of DRS common
stock. DRS's business is different in certain ways from that of ESSI, and
DRS's results of operations, as well as the price of DRS common stock, may
be affected by factors different from those affecting ESSI's results of
operations and the price of ESSI common stock. The price of DRS common stock
may fluctuate significantly following the merger, including as a result of
factors over which DRS has no control. For a discussion of ESSI's businesses
and certain factors to consider in connection with such businesses, see
"Business" and "Management's Discussion and Analysis of Financial Condition
and Results of Operations."

         Factors affecting DRS's business include:

     o   DRS's revenues are dependent on its ability to maintain its government
         business;

     o   DRS's revenues will be adversely affected if it fails to receive
         renewal of follow-on contracts;

     o   DRS's failure to anticipate technical problems, estimate costs
         accurately or control costs with respect to the performance of
         fixed-price contracts may reduce its profit or cause a loss;

     o   DRS may experience production delays if its suppliers fail to deliver
         materials to it;

     o   DRS's backlog is subject to reduction and cancellation;

     o   competition;

     o   military conflict, war or terrorism;

     o   government regulation;


                                     11


     o   technological change; and

     o   DRS's ability to use and safeguard intellectual property.

         THE MARKET PRICE OF DRS COMMON STOCK MAY DECREASE AS A RESULT OF THE
MERGER.

         In the merger, ESSI shareholders will receive consideration that
includes DRS common stock. A number of factors may cause the market price of
such DRS common stock to fluctuate significantly after the merger,
including:

     o   the success of the integration of DRS's and ESSI's operations;

     o   DRS's realization of expected business opportunities and growth
         prospects from the merger;

     o   short-term selling pressure on the market price of DRS common
         stock resulting from sales of DRS shares received by ESSI's
         shareholders in the merger;

     o   DRS's operating results and those of defense companies in general;

     o   the public's reaction to DRS's press releases, announcements and
         filings with the SEC;

     o   changes in earnings estimates or recommendations by research
         analysts;

     o   DRS's ability to reduce the indebtedness undertaken in connection
         with the acquisition of ESSI;

     o   changes in general conditions in the U.S. economy, financial
         markets, global climate or defense industry;

     o   natural disasters, terrorist attacks or acts of war;

     o   other developments affecting DRS or its competitors; and

     o   additional issuances of DRS common stock.

         INTEGRATION OF DRS'S AND ESSI'S OPERATIONS WILL BE COMPLEX,
TIME-CONSUMING AND EXPENSIVE AND MAY ADVERSELY AFFECT THE RESULTS OF
OPERATIONS OF DRS AFTER THE MERGER.

         The anticipated benefits of the merger will depend in part on
whether DRS and ESSI can integrate their operations in an efficient, timely
and effective manner. Integrating DRS and ESSI will be a complex,
time-consuming and expensive process. ESSI will represent DRS's largest and
most significant acquisition to date. Successful integration will require,
among other things, combining the companies':

     o   business development efforts;

     o   key personnel;

     o   geographically separate facilities; and

     o   business and executive cultures.

         DRS and ESSI may not accomplish this integration successfully and
may not realize the benefits contemplated by combining the operations of
both companies. The diversion of management's attention to the integration
effort and any difficulty encountered in combining operations could cause
the interruption of, or a loss of momentum in, the activities of either or
both of the companies' businesses.

                                     12


         IF DRS IS UNABLE TO SUCCESSFULLY INTEGRATE ESSI INTO DRS'S
OPERATIONS ON A TIMELY BASIS, DRS'S PROFITABILITY COULD BE NEGATIVELY
AFFECTED.

         DRS expects that the acquisition of ESSI will result in certain
business opportunities and growth prospects. DRS, however, may never realize
these expected business opportunities and growth prospects. DRS may
experience increased competition that limits its ability to expand its
business, DRS's assumptions underlying estimates of expected cost savings
may be inaccurate or general industry and business conditions may
deteriorate. The acquisition involves numerous risks, including, but not
limited to:

     o   difficulties in assimilating and integrating the operations,
         technologies and products of ESSI;

     o   the diversion of DRS's management's attention from other business
         concerns;

     o   DRS's current operating and financial systems and controls may be
         inadequate to deal with the combined company's operations;

     o   the risk that the combined company will be unable to maintain or
         renew any of ESSI's government contracts;

     o   the risks of DRS entering markets in which it has limited or no
         experience; and

     o   the loss of key employees.

         If these factors limit DRS's ability to integrate the operations of
ESSI successfully or on a timely basis, DRS's expectations of future results
of operations may not be met. In addition, DRS's growth and operating
strategies for ESSI's business may be different from the strategies that
ESSI currently is pursuing. If DRS's strategies are not the proper
strategies for ESSI, it could have a material adverse effect on the
business, financial condition and results of operations of the combined
company. Further, there can be no assurance that DRS will be able to
maintain or enhance the profitability of ESSI or consolidate the combined
company's operations to achieve cost savings.

         DRS'S LEVEL OF INDEBTEDNESS FOLLOWING THE MERGER COULD LIMIT CASH
FLOW AVAILABLE AND COULD ADVERSELY AFFECT ITS OPERATIONS OR ITS ABILITY TO
OBTAIN ADDITIONAL FINANCING, IF NECESSARY. DRS MAY INCUR SUBSTANTIAL
ADDITIONAL INDEBTEDNESS IN THE FUTURE.

         DRS's total debt outstanding as of September 30, 2005 was
approximately $708.4 million. DRS's pro forma indebtedness as of September
30, 2005, after giving effect to the merger and related financing would have
been approximately $1.9 billion. As a result of the increase in debt,
demands on the cash resources of DRS will increase after the merger, which
could have important effects on an investment in DRS common stock. For
example, increased levels of indebtedness could, among other things:

     o   limit the ability of the combined company to obtain additional
         financing for working capital, capital expenditures, acquisitions
         and general corporate purposes or make such financing more costly;

     o   require the combined company to dedicate all or a substantial
         portion of its cash flow to service debt, which will reduce funds
         available for other business purposes, such as capital
         expenditures, research and development, dividends or acquisitions;

     o   limit flexibility in planning for or reacting to changes in the
         markets in which the combined company will compete;

     o   place the combined company at a competitive disadvantage relative
         to its competitors with less indebtedness;

     o   render the combined company more vulnerable to general adverse
         economic and industry conditions; and

     o   make it more difficult to satisfy financial obligations, including
         those relating to the financing of the merger.

                                     13


         The terms of DRS's new financing agreements will include covenants
restricting the activities of DRS and will require repayment of the debt in
certain circumstances. In addition, following the merger, DRS may not be
able to incur substantial additional indebtedness in the future. If DRS adds
new debt, the related risks that it currently faces could intensify.

         If DRS is unable to consummate permanent debt financing of at least
$950.0 million, DRS may enter into a new interim credit facility of up to
$950.0 million that is likely to be on terms substantially more restrictive
and is likely to be more costly than the terms of the contemplated permanent
financing. If any interim loan under the interim facility is not repaid
within one year of the closing of the interim facility, the principal amount
of such loan and any interest on the loan automatically will be exchanged
for senior exchange notes which will bear a higher rate of interest and may
contain other more restrictive terms than the interim credit facility.
Additionally, if the interim facility has not been repaid within 90 days of
the closing of the interim facility, Bear Stearns, in consultation with
Wachovia, may demand that DRS issue and sell senior notes or senior
subordinated notes in an amount sufficient to refinance the interim loans.

         THE MERGER MAY ADVERSELY AFFECT THE COMBINED COMPANY'S ABILITY TO
ATTRACT AND RETAIN KEY ESSI EMPLOYEES.

         ESSI employees may experience uncertainty about their future roles
after the merger. In addition, ESSI employees, including key executives and
members of ESSI's senior management, may determine that they do not desire
to work for DRS for a variety of reasons and may seek early retirement or
other employment opportunities. These factors may adversely affect the
combined company's ability to attract and retain key management,
engineering, sales, marketing and other personnel. There is a continuing
demand for qualified technical personnel and DRS's future growth and success
will depend in part upon its ability to attract, train and retain such
personnel. Competition for personnel in the defense industry is intense. An
inability to attract and maintain a sufficient number of technical
personnel, including ESSI personnel, could have a material adverse effect on
DRS's contract performance and ability to capitalize on market
opportunities.

         A number of senior executive officers of ESSI have agreements
requiring payments in the event of a change in control of ESSI. (See "Item
11 --Executive Compensation--Employment Agreements" and "Item 11--Executive
Compensation--Consulting Agreements"). Moreover, several of these executives
have indicated their desire to retire from ESSI upon completion of the
merger. Departing key employees may be difficult to replace, and their loss
may have a material adverse effect on the combined company's operations.

(2) - Leased


         ESSI also leases certain other small product support and service
facilities located throughout the United States and abroad. ESSI believes
that its current facilities are sufficient for the conduct of its current
level of operations.

         At October 31, 2005, ESSI also owned a 171,000 square foot facility
in St. Louis County, Missouri which it vacated during the year ended October
31, 2003. On November 22, 2005, ESSI completed the sale of this facility for
a sale price of approximately $3.0 million.

ITEM 3.    LEGAL PROCEEDINGS
-------    -----------------

         In December 2004, ESSI was notified by the Enforcement Division of
the SEC of the issuance of a formal order directing a private investigation
captioned In the Matter of Engineered Support Systems, Inc. and that the SEC
had issued subpoenas to various individuals associated with ESSI to produce
certain documents. The SEC staff also requested that ESSI voluntarily
produce certain documents in connection with the investigation. The
subpoenas related to trading in ESSI stock around its earnings releases in
2003 and the adequacy of certain disclosures made by ESSI regarding
related-party transactions in 2002 and 2003 involving insurance policies
placed by ESSI through an insurance brokerage firm in which a director of
ESSI was a principal at the time of the transactions. On or about September
23, 2005, the SEC staff contacted ESSI's counsel and advised that it had
issued a subpoena directed to ESSI and expanded its investigation to include
ESSI's disclosure of a November 2004 stop-work order relating to ESSI's
Deployable Power Generation and Distribution Systems program for the U.S.
Air Force, and trading in ESSI's stock by certain individuals associated
with ESSI.

         In connection with the foregoing SEC investigation, ESSI and
certain of its directors and officers have provided information and
testimony to the SEC. ESSI continues to furnish information requested by the
SEC. On November 14, 2005, ESSI was informed by the Enforcement Division
that one of ESSI's former directors and officers who is currently a
consultant to ESSI has been issued a so-called Wells notice informing him
that the staff of the SEC was considering recommending that the SEC bring a
civil injunctive action against the former officer and director in
connection with the SEC's investigation into trading in ESSI common stock in
2003. A Wells notice provides prospective defendants with an opportunity to
respond to the SEC staff members before the staff makes a formal
recommendation on whether the SEC should pursue disciplinary action against
them. ESSI has not received a Wells notice and continues to cooperate with
the investigation. ESSI is unable to determine at this time either the
timing of the investigation or the impact, if any, which the investigation
could have on ESSI or the combined company following ESSI's proposed merger
with DRS as discussed in Note P to the Consolidated Financial Statements
included elsewhere in this Annual Report on Form 10-K.

         In addition, ESSI is from time to time party to various legal
proceedings, including environmental claims, arising out of its business.
ESSI's management believes that there are no such proceedings pending or
threatened against them which, if determined adversely, would have a
material adverse effect on the consolidated financial position, results of
operations or cash flows of ESSI.

ITEM 4.    SUBMISSION OF MATTERS TO A VOTE OF SHAREHOLDERS
-------    -----------------------------------------------

         There were no matters submitted to a vote of shareholders during
the fourth quarter of the year ended October 31, 2005.

         ESSI's common stock trades on the Nasdaq Stock Market under the
symbol EASI. The number of holders of common stock as of December 20, 2005
was approximately 24,350, including 340 shareholders of record and an
estimated 24,010 persons or entities holding common stock in nominee name.
The following table sets forth the high and low stock prices for each
quarter as provided by the Nasdaq Stock Market, as adjusted to reflect a
three-for-two stock split effected by ESSI on April 15, 2005.

         ESSI has paid a dividend of $.018 per share on a semi-annual basis
during the last two fiscal years. ESSI's pending merger agreement with DRS
provides that ESSI may not declare, set aside or pay any dividend or make
any similar payment with respect its capital stock prior to the effective
date of the merger.

         Effective February 1, 2005, ESSI acquired all of the membership
interests of Spacelink. A portion of the purchase price paid by ESSI at
closing consisted of the issuance by the ESSI of 342,438 shares of its
restricted common stock valued at approximately $13.2 million. ESSI issued
these shares of common stock to the sellers of Spacelink's membership
interests, Spacelink International LTD., a Delaware corporation, and
SatComSolutions LLC, a Delaware limited liability company. The common stock
was issued as a private placement of securities under Section 4(2) of the
Securities Act of 1933.

         The following table provides information as of October 31, 2005
with respect to shares of the common stock that may be issued under ESSI's
existing equity compensation plans:

ITEM 7.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
-------    -----------------------------------------------------------
           AND RESULTS OF OPERATIONS
           -------------------------

CRITICAL ACCOUNTING POLICIES

Revenue Recognition

         ESSI's revenues on long-term contracts, substantially all of which
are directly or indirectly with the U.S. Government, are recognized under
the percentage of completion method and include a proportion of the earnings
that are expected to be realized on the contract in the ratio that
production measures, primarily labor, incurred bear to the total estimated
production measures for the contract. Earnings expectations are based upon
estimates of contract values and costs at completion. Contracts in process
are reviewed on a periodic basis. Adjustments to revenues and earnings are
made in the current accounting period based upon revisions in contract
values and estimated costs at completion. Amounts representing contract
change orders, claims and other items are included in revenues, as
recognized under the percentage of completion method, only when these
amounts can be reliably estimated and


                                     18


realization is probable. Provisions for estimated losses on contracts are
recorded when identified. Substantially all other revenues are recognized
when title passes to the customer. Actual results could differ from ESSI's
estimates and assumptions.

Retirement Obligations

         The determination of ESSI's obligation and expense for pension
and other postretirement benefits is dependent on certain assumptions
developed by ESSI and used by actuaries in calculating such amounts.
Assumptions include, among others, the discount rate and the expected
long-term rate of return on plan assets. Actual results that differ from
assumptions made are accumulated and amortized over future periods and,
therefore, generally affect ESSI's recognized expense and recorded
obligation in such future periods. Significant differences in actual
experience or significant changes in assumptions may materially affect
pension and other postretirement obligations.

Goodwill and Other Long-Lived Assets

         ESSI's management annually reviews goodwill and other long-lived
assets with indefinite useful lives for impairment or whenever events or
changes in circumstances indicate the carrying amount may not be
recoverable. If ESSI determines that the carrying value of the long-lived
asset may not be recoverable, a permanent impairment charge is recorded for
the amount by which the carrying value of the long-lived asset exceeds its
fair value. Fair value is measured based on a discounted cash flow method
using a discount rate determined by management to be commensurate with the
risk inherent in ESSI's current business model. The estimates of cash flows
and discount rate are subject to change due to the economic environment,
including such factors as interest rates, expected market returns and
volatility of markets served. ESSI's management believes that the estimates
of future cash flows and fair value are reasonable; however, changes in
estimates could result in an impairment charge. Intangible assets with
estimated useful lives are amortized over these lives and reviewed for
impairment on a periodic basis.

The following analysis should be read in this context.

RECENT ACQUISITIONS

         Over the past three years, ESSI's net revenues and net income have
increased substantially as a result of both internal growth and several
significant acquisitions.

         During 2005, ESSI acquired three companies operating in the
defense industry. Effective May 1, 2005, ESSI acquired all of the
outstanding stock of Mobilized Systems, which designs, manufacturers and
tests highly specialized trailers, shelters and environmental control
systems, primarily for the defense industry. The purchase price was $17.5
million, net of cash acquired. Of the purchase price, $16.7 million has been
paid as of October 31, 2005. The remaining $0.8 million of consideration is
in the form of long-term promissory notes payable to the sellers. The
purchase price was financed with short-term borrowings under ESSI's
revolving credit facility. The fair value of assets acquired, including
goodwill of $12.7 million and customer-related intangibles of $3.2 million,
was $19.1 million and liabilities assumed totaled $1.6 million. Mobilized
Systems in included within ESSI's Support Systems business segment.

         Effective February 1, 2005, ESSI acquired all of the outstanding
stock of Spacelink, which designs, integrates, operates and maintains
deployed satellite and wireless networks for the DoD, the U.S. intelligence
community and other forward deployed federal agencies and multinational
organizations worldwide. The purchase price, including transaction costs,
was $154.6 million, which included common stock of ESSI with a value of
$13.2 million. The cash consideration was financed with short-term
borrowings under ESSI's revolving credit facility. The purchase price was
net of $2.2 million of cash acquired. The purchase price is also subject to
a working capital adjustment of approximately $2.9 million, tax adjustments
pursuant to Section 338(h)(10) of the Internal Revenue Code of approximately
$2.3 million and certain contingent cash consideration based upon
Spacelink's earnings before


                                     19


interest, taxes, depreciation and amortization, as defined, for each of the
twelve month periods ending January 31, 2006 and 2007. The fair value of
assets acquired, including goodwill of $128.0 million and acquired
customer-related intangibles of $13.8 million, was $165.7 million and
liabilities assumed totaled $11.1 million. Spacelink is included within
ESSI's Support Services business segment.

         On January 7, 2005, ESSI acquired all of the outstanding stock of
PCA, which develops and manufactures electronic test and measurement
equipment provided for electronic warfare and avionics systems primarily to
military customers. The purchase price was $37.6 million and is subject to a
working capital adjustment. The purchase price was financed with ESSI's
existing cash balances. The fair value of assets acquired, including
goodwill of $24.1 million and acquired customer-related intangibles of $6.4
million, was $38.1 million and liabilities assumed totaled $0.5 million. PCA
is included within ESSI's Support Systems business segment.

         During 2004, ESSI acquired one company operating in the defense
industry. Effective December 5, 2003, ESSI acquired all of the outstanding
stock of Pivotal Power, a supplier of high performance static power
conversion equipment primarily to military customers, for approximately
$10.1 million, net of cash acquired. The fair value of assets acquired,
including goodwill of $4.8 million and acquired customer-related intangibles
of $1.2 million, was $11.6 million and liabilities assumed totaled $1.5
million. The purchase price was financed with short-term borrowings under
ESSI's revolving credit facility. Pivotal Power is included within ESSI's
Support Systems business segment.

         During 2003, ESSI acquired two companies operating in the defense
industry. Effective May 1, 2003, ESSI acquired all the capital stock of
TAMSCO, a provider of information technology logistics and digitization
services, and a designer and integrator of telecommunications systems
primarily for the DoD, for approximately $71.1 million in cash plus the
payoff of $14.9 million of TAMSCO indebtedness. The fair value of assets
acquired, including goodwill of $35.9 million and acquired customer-related
intangibles of $29.9 million, was $103.9 million and liabilities assumed
totaled $32.8 million. The purchase price was financed with short-term
borrowings under ESSI's revolving credit facility. TAMSCO is included in
ESSI's Support Services business segment.

         Effective September 24, 2003, ESSI acquired all of the capital
stock of Engineered Environments, Inc. (EEi), a designer and manufacturer of
specialized environmental control units and heat transfer systems for
defense and industrial markets. The purchase of EEi, net of cash acquired,
totaled $16.7 million, which represents the $15.6 million purchase price
plus assumed indebtedness of $1.1 million. The fair value of assets
acquired, including goodwill of $11.6 million and acquired customer-related
intangibles of $2.9 million, was $19.9 million and liabilities assumed
totaled $4.3 million. The purchase price was financed with short-term
borrowings under ESSI's revolving credit facility. EEi is included in ESSI's
Support Systems business segment.

BUSINESS SEGMENTS

         ESSI operates in two business segments: Support Systems and Support
Services. The Support Systems segment engineers and manufactures integrated
military electronics and other military support equipment primarily for the
DoD, as well as related air handling and heat transfer equipment for
commercial and industrial users. Segment products include environmental
control systems, power generation, distribution and conditioning systems,
chemical and biological protection systems, petroleum and water distribution
systems, load management and transport systems, airborne radar systems,
reconnaissance, surveillance and target acquisition systems, avionics test
equipment and other multipurpose military support equipment. The Support
Services segment provides engineering, logistics and training services,
advanced technology services, asset protection systems and services,
telecommunication systems integration and information technology services
primarily for the DoD. The Support Services segment also provides certain
power generation and distribution equipment and vehicle armor installation
to the DoD.

         The following table sets forth net revenues and income from
operations, in millions, for the years ended October 31, 2005, 2004 and 2003
for each of ESSI's business segments:

2005 COMPARED TO 2004

         Consolidated net revenues increased $134.8 million, or 15.2%, in
2005 to $1,018.4 million from $883.6 million in 2004. $85.1 million of this
increase was generated by ESSI's most recently acquired subsidiaries (PCA,
Spacelink and Mobilized Systems) since their respective acquisition dates in
2005. The remaining $49.7 million increase from existing operations included
additional revenues from refurbishment of M1000 Heavy Equipment Transporters
($29.7 million increase), the manufacture and installation of vehicle add-on
armor kits ($47.6 million increase), and additional telecommunications
support programs ($75.4 million increase). These revenue increases were
partially offset by reduced work on the 60-K Tunner Aircraft Cargo Loader
(Tunner), as the production phase of this long-term program ended in the
second quarter of 2005 ($36.5 million decrease), reduced deliveries of
Manportable Surveillance and Target Acquisition Radars (MSTAR) for which a
large military base perimeter security subcontract with Northrop Grumman was
completed in the fourth quarter of 2004 ($57.3 million decrease) and the
impact of temporary production delays on the Deployable Power Generation and
Distribution System (DPGDS), which had been encountering performance issues
on the primary power unit component of the program during 2005 ($41.0
million decrease). After the successful completion of intensive reliability
testing on the primary power unit component of the DPGDS program, the DPGDS
program was returned to full rate production status in the fourth quarter of
2005. Gross profit for 2005 increased $22.3 million, or 10.0%, to $245.0
million (24.1% of consolidated net revenues) from $222.7 million (25.2% of
consolidated net revenues) in 2004. Revenue growth was primarily responsible
for the increase in consolidated gross profit in 2005. However, slightly
reduced gross margins


                                     21


for 2005 reflect a shift in overall business mix towards a greater amount of
Support Services segment revenues, as well as the impact of temporary
production delays and increased estimated costs resulting from performance
issues with the primary power unit component of the DPGDS program. Selling,
general and administrative expense increased $5.6 million, or 5.7%, in 2005
to $103.6 million (10.2% of consolidated net revenues) from $98.0 million
(11.1% of consolidated net revenues) in 2004. Incremental selling, general
and administrative expense for PCA, Spacelink and Mobilized Systems
accounted for $9.0 million of the increase. It should be noted that selling,
general and administrative expense in 2004 included a $5.0 million severance
charge ($4.2 million of which represented a non-cash charge) in connection
with the resignation of a former executive officer. Selling, general and
administrative expense also included amortization expense related to
acquired customer-related intangibles of $9.8 million and $6.7 million in
2005 and 2004, respectively. During 2004, ESSI completed the sales of its
Sanford, Florida and Blue Ash, Ohio facilities, which had been vacated in
conjunction with facility rationalization initiatives. Primarily as a result
of these disposals, ESSI incurred a $1.3 million loss on sale of assets in
2004. As a result of the above, operating income from continuing operations
increased by $18.1 million, or 14.7%, in 2005 to $141.4 million from $123.3
million in 2004.

         Net revenues in 2005 for the Support Systems segment totaled $501.0
million compared to $514.7 million (prior to the elimination of intersegment
revenues in each year) in 2004, a 2.7% decrease. The results for 2005
reflect the inclusion of a combined $23.8 million in net revenues of PCA and
Mobilized Systems since their respective acquisition dates in 2005. During
2005, the segment experienced a $36.5 million revenue reduction on the
Tunner program and a $57.3 million revenue reduction on the MSTAR program.
These decreases were offset by a $29.7 million increase from refurbishment
of M1000 Heavy Equipment Transporters and by a $20.3 million increase in
intersegment work performed for the Support Services segment, primarily
related to the production of vehicle add-on armor kits. Gross profit for the
segment decreased by $9.1 million, or 5.9%, in 2005 to $145.9 million (29.1%
of segment revenues) from $155.0 million (30.1% of segment revenues) in
2004, including a combined $6.9 million gross profit contribution from the
acquisitions of PCA and Mobilized Systems. Segment operating income for 2005
decreased to $87.5 million (17.5% of segment revenues) compared to $93.0
million (18.1% of segment revenues) in 2004 primarily as a result of
reduction in gross profit.

         Net revenues in 2005 for the Support Services segment increased to
$592.7 million, an increase of $149.9 million, or 33.8%, compared to $442.8
million (prior to the elimination of intersegment revenues in each year) in
2004. The most significant year-over-year increases occurred in the
telecommunications support area ($75.4 million increase) and vehicle add-on
armor kit programs ($47.6 million increase). In addition, Spacelink added
$61.3 million of incremental revenues since its acquisition date in 2005.
Partially offsetting these increases were decreased revenues from the DPGDS
program of $41.0 million as previously discussed. Gross profit for the
segment increased by $31.4 million, or 46.4%, in 2005 to $99.1 million
(16.7% of segment revenues) from $67.7 million (15.3% of segment revenues)
in 2004 primarily as a result of increased revenues in 2005 including a
$10.8 million gross profit contribution from the acquisition of Spacelink.
Segment operating income for 2005 totaled $53.9 million (9.1% of segment
revenues) compared to $30.3 million (6.8% of segment revenues) in 2004. The
increase in segment revenues in 2005 provided significant gross profit
contributions which allowed for improved absorption of fixed overhead costs,
leading to the overall improved operating results for the Support Services
segment. However, segment profitability in 2005 was constrained by a
decrease in DPGDS-related revenues in comparison to 2004 as noted above.

         Net interest expense totaled $1.8 million and $0.9 million in 2005
and 2004, respectively. This increase was a result of higher borrowing
levels in 2005 resulting, in large part, from a combined $190.5 million of
cash consideration paid in conjunction with the 2005 acquisitions. The
effective income tax rate was 37.5% for 2005 compared to 38.0% in 2004. This
reduction was primarily due to ESSI's state income tax reduction
initiatives. As a result of the foregoing, net income from continuing
operations increased by 14.9% to $87.2 million (8.6% of consolidated net
revenues) in 2005 compared to $75.9 million (8.6% of consolidated net
revenues) in 2004.

         In the second quarter of 2003, ESSI completed the sale of ESP, a
wholly-owned subsidiary, to a private equity group (Buyer). The Buyer
subsequently alleged that ESSI breached certain representations made under
the related Stock Purchase Agreement (the ESP Agreement) and sought a claim
for associated damages under the binding arbitration provisions of the ESP
Agreement. During the second quarter of 2005, ESSI and the Buyer reached a

                                     22


settlement on this claim, which included modification of ESSI's $3.2 million
note receivable from the Buyer to provide for suspension of interest charges
and payments through July 31, 2006, extension of the note's repayment term
to a balloon payment due in April 2009, and the release of the underlying
real estate collateral securing the note. Because of this settlement, ESSI
recorded a charge for the impairment of the note during the second quarter
of 2005 equal to $1.7 million, or $1.1 million net of income tax. In the
fourth quarter of 2005, ESSI was informed that the Buyer was insolvent. As a
result, ESSI recorded an additional non-cash charge totaling $1.6 million,
or $1.0 million net of income tax, for the impairment of the remainder of
the note in the fourth quarter of 2005. These charges are included within
the discontinued operations section of ESSI's Consolidated Statements of
Income for 2005.

2004 COMPARED TO 2003

         Consolidated net revenues increased $310.9 million, or 54.3%, in
2004 to $883.6 million from $572.7 million in 2003. $181.3 million of this
increase represents an increase in net revenues contributed by TAMSCO, EEi
and Pivotal Power, since their respective acquisition dates in 2003 and
2004. Of the $129.6 million of net revenue growth from all other operating
subsidiaries, ESSI's programs for MSTAR, Field Deployable Environmental
Control Units (FDECU), DPGDS and vehicle add-on armor kits provided the most
significant revenue gains. Gross profit for 2004 increased $84.6 million, or
61.3%, to $222.7 million (25.2% of consolidated net revenues) from $138.1
million (24.1% of consolidated net revenues) in 2003. $23.1 million of this
increase represents an increase in gross profit contributed by TAMSCO, EEi
and Pivotal Power, which had gross profit for either a portion or none of
2003. Of the $61.5 million of gross profit growth from all other operating
subsidiaries, ESSI's programs for MSTAR, FDECU, DPGDS and vehicle add-on
armor kits provided the most significant increases. In addition, MSTAR,
FDECU and DPGDS have significantly higher margins than most of ESSI's
programs, which contributed to a more favorable product mix and a higher
overall gross margin in 2004. Selling, general and administrative expense
increased $34.2 million, or 53.6%, in 2004 to $98.0 million (or 11.1% of
consolidated net revenues) from $63.8 million (11.1% of consolidated net
revenues) in 2003. $21.2 million of this increase was due to an increase in
selling, general and administrative expenses from TAMSCO, EEi and Pivotal
Power. In addition, ESSI incurred a $5.0 million severance charge ($4.2
million of which represented a non-cash charge) in connection with the
resignation of a former executive officer of ESSI. Selling, general and
administrative expense also included amortization expense related to
acquired customer-related intangibles of $6.7 million and $2.8 million in
2004 and 2003, respectively. Under its facility rationalization plan, ESSI
incurred restructuring expense of $0.1 million and $1.8 million,
respectively, in 2004 and 2003 related to the write-down of fixed assets at
the affected facilities and to accrue for expected employee benefits costs.
During 2004, ESSI completed the sales of its Sanford, Florida and Blue Ash,
Ohio facilities, which had been vacated in conjunction with facility
rationalization initiatives. Primarily as a result of these disposals, ESSI
incurred a $1.3 million loss on sale of assets in 2004 compared to a $0.1
million gain on sale of assets in 2003. As a result of the above, operating
income from continuing operations increased by $50.7 million, or 69.8%, in
2004 to $123.3 million from $72.6 million in 2003.

         Net revenues for the Support Systems segment increased by $125.4
million, or 32.2%, to $514.7 million in 2004 from $389.3 million (prior to
the elimination of intersegment revenues in each year) in 2003. The current
year increase was partially attributable to the incremental net revenues of
EEi and Pivotal Power of $11.5 million and $7.9 million, respectively,
during 2004. Programs with the largest revenue gains during 2004 included
the MSTAR, FDECU as well as intersegment work on the DPGDS and vehicle
add-on armor kits being performed for the Support Services segment. Segment
net revenues were partially offset by reduced work on the Tunner program as
production work on that contract ended in mid-2005. Gross profit for the
segment increased by $53.5 million, or 52.7%, to $155.0 million in 2004
(30.1% of segment revenues) from $101.5 million (26.1% of segment revenues)
in 2003. The increase in gross profit was attributable to incremental gross
profit from EEi and Pivotal Power of a combined $7.2 million coupled with
higher profits on MSTAR, FDECU as well as intersegment work on the DPGDS and
vehicle add-on armor kits due to increased revenues and production levels as
noted above. In addition, MSTAR and FDECU have significantly higher margins
than most of the segment's programs, which contributed to a more favorable
product mix and higher gross margins in 2004. Income from operations for the
segment increased by $38.8 million,

or 72.0%, in 2004 to $93.0 million from $54.2 million in 2003. The increase
was the result of higher gross profit partially offset by additional
selling, general and administrative expense in 2004.

         Net revenues for the Support Services segment increased by $232.1
million, or 110.1%, in 2004 to $442.8 million from $210.7 million (prior to
the elimination of intersegment revenues) in 2003. The significant growth in
net revenues was primarily attributable to the inclusion of TAMSCO for a
full year in 2004 versus just six months of post-acquisition results in
2003. TAMSCO reported revenues of $232.0 million in 2004 and $70.1 million
in 2003. Significant revenue increases also were generated by the DPGDS
program and from vehicle add-on armor kits. Gross profit for the segment
increased by $31.1 million, or 85.1%, in 2004 to $67.7 million (15.3% of
segment revenues) from $36.6 million (17.4% of segment revenues) in 2003.
The increase in gross profit was attributable to the higher level of net
revenues in 2004 as discussed above. The decrease in gross margin for the
segment was primarily the result of a significant increase in revenues from
pass-through contract vehicles, such as the Rapid Response and FAST
programs, which generally provide lower than average profit margins. This
decrease was partially offset by revenues from the DPGDS and vehicle add-on
armor programs which provide comparatively higher margins. Income from
operations for the segment increased by $11.9 million in 2004 to $30.3
million from $18.4 million in 2003 as a result of the significant increases
in net revenues and gross profit as compared to the prior year.

         Net interest expense decreased by $0.8 million to $0.9 million in
2004 compared to $1.7 million in 2003 primarily as a result of lower
outstanding borrowings throughout 2004. As of October 31, 2004, ESSI had
completely paid off borrowings against its revolving credit facility and had
cash and cash equivalents of $33.2 million.

         ESSI's effective income tax rate was 38.0% and 39.0% for 2004 and
2003, respectively. The reduction in the effective income tax rate was
primarily the result of ESSI's state income tax reduction initiatives. As a
result of the foregoing, net income from continuing operations increased
75.4% to $75.9 million (8.6% of consolidated net revenues) in 2004 compared
to $43.3 million (7.6% of consolidated net revenues) in 2003.

         During 2002, ESSI formally adopted a plan to dispose of ESP. ESP
was sold to a private equity group in 2003. As a result, ESP's financial
results were reclassified as a discontinued operation in the Consolidated
Financial Statements. Income from discontinued operations totaled $0.3
million, net of income tax, in 2003 and ESSI recorded after-tax losses of
$0.2 million in 2003 to reduce the carrying value of ESP's assets to their
estimated net realizable values less estimated selling costs. See Note E to
the Consolidated Financial Statements.

OUTLOOK FOR 2006 AND FUTURE

         On September 21, 2005, ESSI and DRS entered into a definitive
agreement which provides for the acquisition by DRS of all the outstanding
common stock of ESSI for approximately $1.9 billion, or $43.00 per share
(subject to possible adjustment), through a combination of cash and DRS
common stock. Pending customary regulatory approvals and other closing
conditions, including approval by ESSI and DRS shareholders, the transaction
is expected to close before March 31, 2006.

         ESSI continues to believe that significant growth opportunities
exist within the military support equipment, electronics and logistics
support segments of the defense industry in response to (1) the current
fragmentation within the industry; (2) the DoD's emphasis on awarding
contracts on the basis of "best value;" (3) the DoD's increasing outsourcing
of engineering, design and logistics services to contractors; (4) heightened
military operations around the globe; and, (5) overall increases in defense
spending by the DoD. In addition to supporting future merger integration
activities with DRS, ESSI's focus for 2006 includes the continued
rationalization of its existing defense operations in order to leverage its
infrastructure and achieve additional operational synergies.

LIQUIDITY AND CAPITAL RESOURCES

         On January 27, 2005, ESSI and its banks entered into an Amended and
Restated Credit Agreement (Amended Credit Agreement). The Amended Credit
Agreement replaced ESSI's previous credit agreement dated April 23, 2003.

                                     24


The Amended Credit Agreement, which expires January 27, 2010, provides for a
$200 million unsecured revolving credit facility. ESSI may request, subject
to certain conditions, an increase of up to $100 million in the amount of
the aggregate commitment under the Amended Credit Agreement.

         Borrowings under the Amended Credit Agreement bear interest, at
ESSI's option, at either the Eurodollar rate plus an applicable margin, or
at the higher of the prime rate or the federal funds rate plus one-half of
one percent. The margin applicable to the Eurodollar rate varies from 0.625%
to 1.375% depending upon ESSI's ratio of total indebtedness to earnings
before interest, taxes, depreciation and amortization (leverage ratio). The
Amended Credit Agreement contains certain covenants, including maintaining
net worth of at least $265 million, plus 50% of the sum, to extent positive,
of ESSI's consolidated net income and other comprehensive income (loss)
reported after October 31, 2004, plus the net proceeds of all subsequent
equity offerings. ESSI also must comply with certain financial covenants,
including maintenance of a leverage ratio of no greater than 2.75 to 1. ESSI
is also subject to various other financial and operating covenants and
maintenance criteria, including restrictions on ESSI's ability to incur
additional indebtedness, make investments, pay dividends over a specified
amount, create liens, dispose of material assets and enter into merger
transactions and acquisitions. As of October 31, 2005, ESSI had $45 million
in borrowings against the Amended Credit Facility, and was in compliance
with all applicable covenants.

         ESSI's working capital needs are generally funded through cash flow
from operations and the revolving credit facility. At October 31, 2005,
ESSI's working capital and ratio of current assets to current liabilities
were $71.9 million and 1.40 to 1, respectively, compared with $112.0 million
and 1.85 to 1 at October 31, 2004. During 2005, ESSI expended cash totaling
$190.5 million in conjunction with the acquisitions of PCA, Spacelink and
Mobilized Systems. ESSI financed these transactions with available cash
resources and short-term borrowings under its revolving credit facility. The
significant changes in working capital and the ratio of current assets to
current liabilities from October 31, 2004 were due to these acquisitions and
the related increase in short-term borrowings against ESSI's revolving
credit facility.

         Net cash provided by operations totaled $101.9 million in 2005
compared to net cash provided by operations of $66.6 million in 2004. This
$35.3 million increase was a result of the significantly improved operating
results, as discussed above, as well as a $20.6 million reduction in working
capital growth in 2005 from the prior year. ESSI's investment in property,
plant and equipment totaled $12.1 million and $8.0 million in 2005 and 2004,
respectively. This $4.1 million increase was primarily due to the
construction of the Company's 80,000 square foot hanger to be used for
aircraft repair and maintenance. In 2004, ESSI realized $5.7 million in
proceeds primarily related to the sales of its Sanford, Florida and Blue
Ash, Ohio facilities. ESSI anticipates that capital expenditures in 2006
should not exceed $15.0 million. During 2005 and 2004, ESSI received
proceeds, including related income tax benefits, of $31.8 million and $56.5
million, respectively, related to the exercise of stock options, which are
classified as financing cash flows within the Consolidated Statements of
Cash Flow. ESSI management believes that cash flow generated from
operations, together with its revolving credit facility, will provide the
necessary resources to meet ESSI's needs for the foreseeable future.

         Total contractual and contingent obligations, in thousands, as of
October 31, 2005 are as follows:

                                     25


         While contingent obligations are included in the table above, ESSI
does not expect to fund the full amounts indicated for letters of credit.
Lease expense totaled $5.9 million, $5.0 million and $4.2 million for the
years ended October 31, 2005, 2004 and 2003, respectively.

INFLATION

         Since a significant portion of ESSI's contracts with the DoD are at
fixed prices, inflation can affect the ultimate profit to be realized on
them. Some contracts have price adjustment provisions that limit the impact
of inflation on profits. In addition, ESSI's volume purchasing and forward
purchasing policies serve to limit the effects of inflation. ESSI considers
potential inflation in preparation of contract proposals and bids. In
addition, ESSI's commercial and industrial products are predominantly
custom-made. Therefore, the impact of inflation on operating results
typically is not significant. ESSI attempts to alleviate inflationary
pressures on commercial and industrial products by increasing selling prices
to help offset rising costs (subject to competitive conditions), increasing
productivity and improving manufacturing techniques. Because of these
factors, management does not believe that inflation has had, or that
anticipated inflation will have, a significant effect on ESSI's operations.

BUSINESS AND MARKET CONSIDERATIONS

         Approximately 96% of ESSI's consolidated net revenues for 2005 were
directly or indirectly derived from defense orders by the U.S. government or
its agencies. As of October 31, 2005, ESSI's funded backlog of orders
totaled $689.8 million, with related customer options of an additional
$1,487.1 million. These amounts compare to funded backlog of $588.1 million
and related customer options of an additional $849.2 million as of October
31, 2004.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

         In October 2004, the U.S. Congress passed the American Jobs
Creation Act of 2004 (the Jobs Creation Act). The Jobs Creation Act includes
numerous provisions that may materially affect business practices and
accounting for income taxes. For companies that pay U.S. income taxes on
manufacturing activities in the U.S., the Jobs Creation Act provides a
phased-in deduction from taxable income equal to a stipulated percentage of
qualified income from domestic production activities. In December 2004, the
Financial Accounting Standards Board (FASB) issued two FASB Staff Positions
(FSP) regarding the accounting implications of the Jobs Creation Act related
to (1) the deduction for qualified domestic production activities (FSP
109-1) and (2) the one-time tax benefit for the repatriation of foreign
earnings (FSP 109-2). This guidance applies to financial statements for
periods ending after the date the Jobs Creation Act was enacted. The Jobs
Creation Act also provides for a change in the period of application of for
foreign tax credits, elimination of the 90-percent limitation of foreign tax
credits against Alternative Minimum Tax, expanded disallowance of interest
on convertible debt, and tax shelter disclosure penalties. ESSI adopted FSP
109-1 and FSP 109-2 in the first quarter of 2005. The one-time tax benefit
for the repatriation of foreign earnings does not apply to the Company. ESSI
anticipates that the Jobs Creation Act and related FASB pronouncements will
have a material impact its consolidated financial statements in future
periods. However, this impact was not material for the year ended October
31, 2005.

         In November 2004, the FASB issued Statement of Financial Accounting
Standards (SFAS) No. 151, "Inventory Costs - an amendment of ARB No. 43,
Chapter 4." SFAS 151 seeks to clarify the accounting for abnormal amounts of
idle facility expense, freight, handling costs and wasted material
(spoilage) in the determination of inventory carrying costs. The statement
requires such costs to be treated as current period expense. This statement
is effective November 1, 2005 for ESSI. ESSI does not believe that the
adoption of SFAS 151 will have a significant impact on the consolidated
financial statements.

                                     26


         In December 2004, the FASB issued SFAS 123 (revised 2004),
"Share-Based Payment", (SFAS 123R). SFAS 123R requires companies to expense
the value of employee stock options and similar awards. SFAS 123R is
effective November 1, 2005 for ESSI. ESSI is currently evaluating its
compensation policies and practices, along with the impact of SFAS 123R on
its consolidated results of operations.

         In May 2005, the FASB issued SFAS 154, "Accounting Changes and
Error Corrections - a Replacement of APB Opinion No. 20 and FASB Statement
No. 3" (SFAS 154). SFAS 154 requires retrospective application to prior
period financial statements of changes in accounting principle, unless it is
impracticable to determine either the period-specific effects or the
cumulative effect of the change. SFAS 154 also redefines "restatement" as
the revising of previously issued financial statements to reflect the
correction of an error. This statement is effective for accounting changes
and corrections of errors made in fiscal years beginning after December 15,
2005 (or fiscal 2007 for ESSI). ESSI does not believe that the adoption of
SFAS 154 will have a significant impact on the consolidated financial
statements.

ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
--------    ----------------------------------------------------------

         Market risks relating to ESSI's operations result primarily from
changes in interest rates. Given ESSI's existing debt levels, significant
cash flows and anticipated expenditures, ESSI's management has not utilized
interest rate swaps or other derivative contracts to hedge this risk since
November 2002. ESSI's management does not believe its exposure to interest
rate fluctuations has had, or will have, a significant impact on ESSI's
operations. A 10% increase in ESSI's effective interest rate would have
resulted in additional interest expense of $0.2 million for the year ended
October 31, 2005.

                      ENGINEERED SUPPORT SYSTEMS, INC.
                 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                  (in thousands, except per share amounts)

NOTE A -- SIGNIFICANT ACCOUNTING POLICIES

         Basis of Presentation and Principles of Consolidation: The
Consolidated Financial Statements include the accounts of Engineered Support
Systems, Inc. (Company) and its wholly-owned subsidiaries. These
subsidiaries are organized within the Company's two business segments:
Support Systems and Support Services. The Support Systems segment includes
the operations of Systems & Electronics Inc. (SEI), Keco Industries, Inc.
(Keco), Engineered Air Systems, Inc. (Engineered Air), Engineered Coil
Company, d/b/a Marlo Coil (Marlo Coil), Engineered Electric Company, d/b/a
Fermont (Fermont), Universal Power Systems, Inc. (UPSI), Engineered
Environments, Inc. (EEI), Pivotal Power Inc. (Pivotal Power), Prospective
Computer Analysts, Inc. (PCA) and Mobilized Systems, Inc. (Mobilized
Systems). The Support Services segment includes the operations of Technical
and Management Services Corporation (TAMSCO), Radian, Inc. (Radian),
Spacelink International, LLC (Spacelink) and ESSIbuy.com, Inc. (ESSIbuy).
All material intercompany accounts and transactions have been eliminated in
consolidation.

         Industry Information: The Company's Support Systems segment
designs, engineers and manufactures integrated military electronics and
other military support equipment primarily for the U.S. Department of
Defense (DoD), as well as related heat transfer and air handling equipment
for domestic commercial and industrial users. Segment products include
environmental control systems, load management and transport systems, power
generation, distribution and conditioning systems, airborne radar systems,
reconnaissance, surveillance and target acquisition systems, chemical and
biological protection systems, petroleum and water distribution systems and
other multipurpose military support equipment. The Company's Support
Services segment provides engineering services, logistics and training
services, advanced technology services, asset protection systems and
services, telecommunication systems integration and information technology
services primarily for the DoD. The Support Services segment also provides
certain power generation and distribution equipment and vehicle armor
installation to the DoD. Substantially all revenues are directly or
indirectly derived from contracts with the U.S. Government.

         Use of Estimates: In preparing these financial statements,
management makes estimates and uses assumptions that affect some of the
reported amounts and disclosures. Actual results could differ from these
estimates and assumptions.

         Cash and Cash Equivalents: Cash equivalents include temporary
investments with original maturities of three months or less.

         Revenue Recognition: Revenues on long-term contracts,
substantially all of which are with the U.S. government, are recognized
under the percentage of completion method and include a proportion of the
earnings that are expected to be realized on the contract in the ratio that
production measures, primarily labor, incurred bear to the total estimated
production measures for the contract. Earnings expectations are based upon
estimates of contract values and costs at completion. Contracts in process
are reviewed on a periodic basis. Adjustments to revenues and earnings are
made in the current accounting period based upon revisions in contract
values and estimated costs at completion. Amounts representing contract
change orders, claims and other items are included in revenues, as
recognized under the percentage of completion method, only when these
amounts can be reliably estimated and realization is probable. Provisions
for estimated losses on contracts are recorded when identified.
Substantially all other revenues are recognized when title passes to the
customer.

         Stock-Based Compensation: The Company applies Accounting Principles
Board Opinion No. 25, "Accounting for Stock Issued to Employees," and
related interpretations in accounting for all stock option plans. (See Note
J for a further description of these plans.) Accordingly, no compensation
expense has been recognized for stock option awards. The following table
illustrates the effect on net income and earnings per share had the Company
applied the fair value recognition provisions of Statement of Financial
Accounting Standards (SFAS) 123, "Accounting for Stock-Based Compensation,"
to stock option awards.

         The fair value of options at the grant date was estimated using
the Black-Scholes model with the following weighted average assumptions for
2005, 2004 and 2003, respectively: an expected life of 2.5, 1.5 and 1.5
years; volatility of 35%, 26%, and 36%; a dividend yield of 0.08%, 0.11% and
0.18%; and a risk-free interest rate of 3.59%, 3.52%, and 3.25%.

         The weighted average fair value of options granted in 2005, 2004
and 2003 was $9.03, $5.37 and $5.03, respectively.

         Fair Value of Financial Instruments: For purposes of financial
reporting, the Company has determined that the fair value of the Company's
financial instruments, including cash and cash equivalents, accounts
receivable, accounts payable, accrued liabilities and long-term debt,
approximates book value at October 31, 2005 and 2004, based on either their
short-term nature or on terms currently available to the Company in
financial markets.

         Credit Risk: Financial instruments which potentially subject the
Company to concentrations of credit risk consist principally of cash and
cash equivalents, and accounts receivable. At October 31, 2005 and 2004, the
Company's cash and cash equivalents were primarily invested in money market
accounts at a financial institution. Management believes the credit risk is
limited due to the short-term nature of these funds. Management believes the
credit risk related to accounts receivable is limited due to the fact that
76% and 79% of accounts receivable at October 31, 2005 and 2004,
respectively, are due from the U.S. government and its agencies. Allowances
for anticipated doubtful accounts are provided based on historical
experience and evaluation of specific accounts. The allowance for doubtful
accounts was $1,060 and $90 at October 31, 2005 and 2004, respectively.

         Interest Rate Risk: Interest rate risk is managed through a
portfolio of variable- and fixed-rate debt that management deems
appropriate. Furthermore, the Company will periodically convert its
variable-rate debt to fixed rates via interest rate swaps. Given the
Company's outstanding debt position and anticipated cash flows, management
does not believe its exposure to interest rate fluctuations has had, or will
have, a significant impact on the Company's operations. The Company,
therefore, had no interest rate swaps as of October 31, 2005.

         Contracts in Process and Inventories: Contracts in process and
inventories represent accumulated contract costs, estimated earnings thereon
based upon the percentage of completion method and contract inventories
reduced by the contract value of delivered items. Accumulated contract costs
and inventories are stated at actual costs incurred and consist of direct
engineering, production, tooling, applicable overhead and other costs
(excluding selling, general and administrative costs which are charged
against income as incurred). Title to or a security interest in certain
items included in contracts in process and inventories is vested in the U.S.
government by reason of the progress payment provisions of related
contracts. In accordance with industry standards, contracts in process and
inventories related to long-term contracts are classified as current assets
although a portion may not be realized within one year. Substantially all
inventories related to contracts not accounted for under the percentage of
completion method are valued at the lower of cost or market using the
first-in, first-out method.

         Property, Plant and Equipment: Property, plant and equipment are
stated at cost and are depreciated using the straight-line method over their
estimated useful lives of 15 to 40 years for buildings and improvements, 5
to 15 years for machinery and equipment, and 3 to 10 years for furniture and
fixtures. Depreciation expense totaled $7,752 in 2005, $5,627 in 2004 and
$5,387 in 2003.

                                     33


         Income Taxes: The income tax provision is based on earnings
reported in the financial statements. Deferred income taxes are provided for
the tax effects of temporary differences between financial and income tax
reporting using current statutory tax rates.

         Impairment of Long-lived Assets: Long-lived assets, including
goodwill, are reviewed for impairment annually or whenever events or changes
in circumstances indicate that the carrying amount may not be recoverable.
If the sum of the expected future undiscounted cash flows is less than the
carrying amount of the asset, a loss is recognized for the difference
between the fair value and the carrying value of the asset.

         Earnings Per Share: Basic earnings per share is based on average
basic common shares outstanding, after the effect to the stock split
described in Note O, of 41,329 in 2005, 38,987 in 2004 and 36,305 in 2003.
Diluted earnings per share is based on average diluted common shares
outstanding, after giving effect to the stock split described in Note O, of
43,232 in 2005, 41,799 in 2004 and 38,757 in 2003. Average diluted common
shares outstanding include common stock equivalents, which represent common
stock options as computed using the treasury stock method.

         Treasury Stock: Shares of treasury stock are valued at cost using
the first-in, first-out method.

         Recently Issued Accounting Pronouncements: In October 2004, the
U.S. Congress passed the American Jobs Creation Act of 2004 (the Jobs
Creation Act). The Jobs Creation Act includes numerous provisions that may
materially affect business practices and accounting for income taxes. For
companies that pay U.S. income taxes on manufacturing activities in the
U.S., the Jobs Creation Act provides a phased-in deduction from taxable
income equal to a stipulated percentage of qualified income from domestic
production activities. In December 2004, the Financial Accounting Standards
Board (FASB) issued two FASB Staff Positions (FSP) regarding the accounting
implications of the Act related to (1) the deduction for qualified domestic
production activities (FSP 109-1) and (2) the one-time tax benefit for the
repatriation of foreign earnings (FSP 109-2). This guidance applies to
financial statements for periods ending after the date the Act was enacted.
The Jobs Creation Act also provides for a change in the period of
application for foreign tax credits, elimination of the 90-percent
limitation of foreign tax credits against Alternative Minimum Tax, expanded
disallowance of interest on convertible debt, and tax shelter disclosure
penalties. The Company adopted FSP 109-1 and FSP 109-2 in the first quarter
of 2005. The one-time tax benefit for the repatriation of foreign earnings
does not apply to the Company. The Company anticipates that the Jobs
Creation Act and related FASB pronouncements will have a material impact on
the Company's consolidated financial statements in future periods. However,
this impact was not material for the year ended October 31, 2005.

         In November 2004, the FASB issued Statement of Financial Accounting
Standards (SFAS) 151, "Inventory Costs - an amendment of ARB No. 43, Chapter
4." SFAS 151 seeks to clarify the accounting for abnormal amounts of idle
facility expense, freight, handling costs and wasted material (spoilage) in
the determination of inventory carrying costs. The statement requires such
costs to be treated as a current period expense. This statement is effective
November 1, 2005 for the Company. The Company does not believe that the
adoption of SFAS 151 will have a significant impact on its consolidated
financial statements.

         In December 2004, the FASB issued SFAS No. 123 (revised 2004),
"Share-Based Payment," (SFAS 123R). SFAS 123R requires companies to expense
the value of employee stock options and similar awards. SFAS 123R is
effective November 1, 2005 for the Company. The Company is currently
evaluating its compensation policies and practices, along with the impact of
SFAS 123R on its consolidated results of operations.

         In May 2005, the FASB issued SFAS 154, "Accounting Changes and
Error Corrections - a Replacement of APB Opinion No. 20 and FASB Statement
No. 3." SFAS 154 requires retrospective application to prior period
financial statements of changes in accounting principle, unless it is
impracticable to determine either the period-specific effects or the
cumulative effect of the change. SFAS 154 also redefines "restatement" as
the revising of previously issued financial statements to reflect the
correction of an error. This statement is effective for accounting changes
and corrections of errors made in fiscal years beginning after December 15,
2005 (or fiscal 2007 for the Company). The Company does not believe that the
adoption of SFAS 154 will have a significant impact on its consolidated
financial statements.

NOTE B -- ACQUISITIONS

         On January 7, 2005, the Company acquired all of the outstanding
stock of PCA, which develops and manufactures electronic test and
measurement equipment provided for electronic warfare and avionics systems
primarily to military customers. The purchase price was $37.6 million and is
subject to a working capital adjustment. The purchase price was financed
with the Company's existing cash balances. The fair value of assets
acquired, including goodwill of $24.1 million and acquired customer-related
intangibles of $6.4 million, was $38.1 million and liabilities assumed
totaled $0.5 million.

         Effective February 1, 2005, the Company acquired all of the
outstanding stock of Spacelink, which designs, integrates, operates and
maintains deployed satellite and wireless networks for the DoD, the U.S.
intelligence community and other forward deployed federal agencies and
multinational organizations worldwide. The purchase price, including
transaction costs, was $154.6 million, which included common stock of the
Company with a value of $13.2 million. The cash consideration was financed
with short-term borrowings under the Company's revolving credit facility.
The purchase price was net of $2.2 million of cash acquired. The purchase
price is also subject to a working capital adjustment of approximately $2.9
million, tax adjustments pursuant to Section 338(h)(10) of the Internal
Revenue Code of approximately $2.3 million and to certain contingent cash
consideration based upon Spacelink's earnings before interest, taxes,
depreciation and amortization, as defined, for each of the twelve month
periods ending January 31, 2006 and 2007. The fair value of assets acquired,
including goodwill of $128.0 million and acquired customer-related
intangibles of $13.8 million, was $165.7 million and liabilities assumed
totaled $11.1 million.

         The following unaudited pro forma summary presents the combined

         Effective May 1, 2005, the Company acquired all of the outstanding
stock of Mobilized Systems, which designs, manufacturers and tests highly
specialized trailers, shelters and environmental control systems, primarily
for the defense industry. The purchase price was $17.5 million, net of cash
acquired, of which $16.7 million has been paid as of October 31, 2005 as
reflected in the Consolidated Statement of Cash Flows. The remaining $0.8
million of consideration is in the form of long-term promissory notes
payable to the sellers. The cash portion of the purchase price was financed
with short-term borrowings under the Company's revolving credit facility.
The fair value of assets acquired, including goodwill of $12.7 million and
customer-related intangibles of $3.2 million, was $19.1 million and
liabilities assumed totaled $1.6 million.

         On December 5, 2003, the Company acquired all of the outstanding
stock of Pivotal Power, a supplier of high-performance static power
conversion equipment primarily to military customers. The purchase price was
approximately $10.1 million, net of cash acquired. The fair value of assets
acquired, including goodwill of $4.8 million and acquired customer-related
intangibles of $1.2 million, was $11.6 million and liabilities assumed
totaled $1.5 million. The purchase price was financed with short-term
borrowings under the Company's revolving credit facility.

         On September 24, 2003, the Company acquired all of the outstanding
common stock of EEI, a designer and manufacturer of specialized
environmental control units and heat transfer systems for defense and
industrial markets. The purchase price was approximately $15.6 million. The
purchase of EEI, net of cash acquired, totaled $16.7 million in the
Consolidated Statements of Cash Flows, which represents the $15.6 million
purchase price plus assumed indebtedness of $1.1 million. The initial
purchase price allocation for EEI was based on preliminary information,
which was subject to adjustment upon obtaining complete valuation
information. During the fourth quarter of 2004, the Company completed its
valuation and reclassified $2.9 million from goodwill, as recorded in the
preliminary allocation, to acquired customer-related intangibles and
recorded a $0.5 million non-cash charge in the quarter ended October 31,
2004 to reflect the related amortization expense from acquisition date. The
fair value of assets acquired, including goodwill of $11.6 million and
acquired customer-


                                     36


related intangibles of $2.9 million, was $19.9 million and liabilities
assumed totaled $4.3 million. The purchase price was financed with
short-term borrowings under the Company's revolving credit facility.

         On May 1, 2003, the Company acquired all of the outstanding common
stock of TAMSCO, a provider of information technology logistics and
digitization services and a designer and integrator of telecommunication
systems primarily for the DoD. The purchase price was approximately $71.1
million, which is net of $0.1 million of cash acquired. Approximately $1.1
million of the purchase price has not been paid subject to final collection
of accounts receivable. In connection with this transaction, the Company
also assumed and paid $14.9 million of TAMSCO indebtedness. The purchase of
TAMSCO, net of cash acquired, totals $84.9 million in the Consolidated
Statements of Cash Flows, which represents the $71.1 million purchase price
plus assumed indebtedness of $14.9 million less $1.1 million of purchase
price not yet paid. The initial purchase price allocation for TAMSCO was
based on preliminary information, which was subject to adjustment upon
obtaining complete valuation information. During the second quarter of 2004,
the Company completed its valuation of the assets acquired and liabilities
assumed. As a result, the Company reclassified $29.9 million from goodwill,
as recorded in the preliminary allocation, to acquired customer-related
intangibles and recorded a $2.2 million non-cash charge in the quarter ended
April 30, 2004 to reflect the related amortization expense from acquisition
date. The fair value of assets acquired, including goodwill of $35.9 million
and acquired customer-related intangibles of $29.9 million, was $103.9
million and liabilities assumed totaled $32.8 million. The purchase price
was financed with short-term borrowings under the Company's revolving credit
facility.

         The following unaudited pro forma summary presents the combined
historical results of operations, after giving effect to the stock split
described in Note O, for the year ended October 31, 2003 as adjusted to
reflect the TAMSCO purchase transaction assuming the acquisition had
occurred at November 1, 2002. These pro forma results are not necessarily
indicative of the combined results that would have occurred had the
acquisition actually taken place on November 1, 2002, nor are they

NOTE D -- OPERATIONAL RESTRUCTURING

         During the quarter ended April 30, 2003, the Company announced a
restructuring plan under which electronics assembly work performed at the
Sanford, Florida facility of the Company's SEI subsidiary would be relocated
to alternate SEI facilities. Statement of Financial Accounting Standards No.
146 (SFAS 146), "Accounting for Costs Associated with Exit or Disposal
Activities," applies to all disposal activities initiated after December 31,
2002. SFAS 146 requires that a liability for employee termination costs
associated with an exit or disposal activity be recognized when the
liability is incurred. In accordance with SFAS 146, the Company recorded
restructuring expense of $2.1 million in the year ended October 31, 2003 and
$0.1 million in the year ended October 31, 2004, consisting of $1.3 million
for severance and related benefits and $0.9 million for non-cash costs
associated with the write-down of the Sanford, Florida facility to its fair
market value. The Company anticipates that it will record no additional
restructuring expense related to this plan. The plan involved the
termination of 107 employees, all of which had been terminated as of
October 31, 2004. All related severance costs had been paid as of October 31,
2004.

NOTE E -- DISCONTINUED OPERATIONS

         The Company completed the sale of Engineered Specialty Plastics,
Inc. (ESP), a wholly-owned subsidiary, in the quarter ended April 30, 2003
to a private equity group (the Buyers). The Buyers subsequently alleged that
the Company breached certain representations made under the related Stock
Purchase Agreement (the Agreement) and sought a claim for associated damages
under the binding arbitration provisions of the Agreement. During the
quarter ended April 30, 2005, the Company and the Buyers reached a
settlement on this claim, which included modification of the Company's $3.2
million note receivable from the Buyers to provide for suspension of
interest charges and payments through July 31, 2006, extension of the note's
repayment term to a balloon payment due in April 2009, and the release of
the underlying real estate collateral securing the note. Because of this
settlement, the Company recorded a charge for the impairment of the note
during the quarter ended April 30, 2005 equal to $1.7 million, or $1.1
million net of income tax. During the quarter ended October 31, 2005, the
Company was informed that the Buyers had liquidated all ESP assets, and the
Company reserved an additional $1.6 million, or $1.0 million net of income
tax, for the impairment of the remainder of the note. These amounts are
reflected in discontinued operations on the Consolidated Statements of
Income for the year ended October 31, 2005. Certain information with respect
to the discontinued operations of ESP is as follows:

NOTE H -- NOTES PAYABLE

         On January 27, 2005, the Company entered into an Amended and
Restated Credit Agreement (Amended Credit Agreement) with its banks. The
Amended Credit Agreement replaced the Company's previous credit agreement
dated April 23, 2003. The Amended Credit Agreement, which expires January
27, 2010, provides for a $200 million unsecured revolving credit facility.
The Company may request, subject to certain conditions, an increase of up to
$100 million in the amount of the aggregate commitment under the Amended
Credit Agreement.

         Borrowings under the Amended Credit Agreement bear interest, at the
Company's option, at either the Eurodollar rate plus an applicable margin,
or at the higher of the prime rate or the federal funds rate plus one-half
of one percent. The margin applicable to the Eurodollar rate varies from
0.625% to 1.375% depending upon the Company's ratio of total indebtedness to
earnings before interest, taxes, depreciation and amortization (leverage
ratio). The Amended Credit Agreement contains certain covenants, including
maintaining net worth of at least $265 million, plus 50% of the sum, to the
extent positive, of the Company's consolidated net income and other
comprehensive income (loss) reported after October 31, 2004, plus the net
proceeds of all subsequent equity offerings. The Company must also comply
with certain financial covenants, including maintenance of a leverage ratio
of no greater than 2.75 to 1. The Company is also subject to various other
financial and operating covenants and maintenance criteria, including
restrictions on the Company's ability to incur additional indebtedness, make
investments, create liens, dispose of material assets and enter into merger
transactions and acquisitions. As of October 31, 2005, the Company was in
compliance with all applicable covenants of the Amended Credit Agreement. No
compensating balance is required or maintained related to the Amended Credit
Agreement.

         As of October 31, 2005, the Company had $45.0 million in borrowings
under the Amended Credit Agreement. Borrowings under the Amended Credit
Facility and the Company's previous revolving credit facility averaged $26.5
million for the year ended October 31, 2005. Borrowings under the Amended
Credit Agreement are unsecured and are guaranteed by the Company.

         Interest paid was $2,460 in 2005, $1,370 in 2004 and $2,215 in 2003.

NOTE K -- PENSION AND OTHER POSTRETIREMENT BENEFITS

         Effective September 30, 1999, the Company acquired SEI and assumed
the pension and other postretirement benefit plans related to SEI's
employees and non-employee participants. Substantially all employees of SEI
are covered by defined benefit or defined contribution pension plans. In
addition, certain retirees of SEI are eligible for postretirement health and
life insurance benefits. To qualify for postretirement health and life
insurance benefits, an SEI employee must retire at age 55 or later and the
employee's age plus service must equal or exceed 75. Retiree contributions
are defined as a percentage of medical premiums. Consequently, retiree
contributions increase with increases in the medical premiums. The life
insurance plans are noncontributory and provide coverage of a flat dollar
amount for qualifying retired SEI employees.

         All former full-time employees of Engineered Air who were covered
by a collective bargaining agreement are also covered by a defined benefit
pension plan. These SEI and Engineered Air benefits are provided under
defined benefit pay-related and flat-dollar plans, which are primarily
non-contributory. Annual Company


                                     43


contributions to retirement plans equal or exceed the minimum funding
requirements of the Employee Retirement Income Security Act or other
applicable regulations.

are presented below for 2005, 2004 and 2003:

         The postretirement plan amendment is that prescription drug
coverage will no longer be offered to participants after the age of 65. This
change is being made concurrently with the new Medicare Part D coverage for
prescription drugs effective in 2006. Under the new arrangement, retiree
contributions provide for 100% of the cost for post-65 coverage.

         Assumptions used in accounting for the defined benefit plans in
2005, 2004 and 2003 were a discount rate of 5.50%, 5.75% and 6.00%,
respectively, a rate of compensation increase of 3.75% in each year, and an
expected long-term rate of return on assets of 8.75% in each year. A 1%
increase in the discount rate would decrease net pension costs for 2005 and
the accrued benefit cost at October 31, 2005 by $1.8 million and a 1%
decrease in the discount rate would increase net pension benefit costs for
2005 and the accrued benefit cost at October 31, 2005 by $1.9 million. A 1%
increase in the expected long-term rate of return on assets would decrease
net pension costs for 2005 and the accrued benefit cost at October 31, 2005
by $0.8 million and a 1% decrease in the expected long-term rate of return
on assets would increase net pension benefit costs for 2005 and the accrued
benefit cost at October 31, 2005 by $0.8 million.

         Assumptions used in accounting for other postretirement benefits in
2005, 2004 and 2003 were a discount rate 5.50% 5.75% and 6.00%,
respectively, and a health care cost trend of 9.5%, 9.5% and 10.0%,
respectively, decreasing 0.5% annually to an ultimate rate of 5.5%. A 1%
increase in the discount rate would decrease net other benefit costs for
2005 by $0.1 million and a 1% decrease in the discount rate would increase
net other benefit costs for 2005 by $0.1 million. A 1% increase in the
health care cost trend rate for each year would increase the October 31,
2005 net benefit obligation by approximately $12, while a 1% decrease in the
health care cost trend rate for each year would decrease the October 31,
2005 net benefit obligation by approximately $14.

         The accumulated benefit obligation for defined benefit pension
plans was $123.8 million and $111.7 million at October 31, 2005 and 2004,
respectively.

         The weighted average asset allocation and the target allocation for
the Company's pension benefit plans, by asset category, is as follows:

         The Company's pension plan assets are managed by outside investment
managers and assets are rebalanced when the target ranges are exceeded.
Pension plan assets consist of marketable securities including common
stocks, bonds, real estate and interest-bearing deposits. The Company's
investment strategy with respect to pension assets is to achieve a total
rate of return (income and capital appreciation) that is sufficient to
provide retirement benefits to all eligible and future retirees of the
pension plans. The Company regularly monitors performance and compliance
with investment guidelines.

         The Company sponsors the Engineered Support Systems, Inc. 401(k)
and Employee Stock Ownership Plan (ESOP), which covers all employees of
Engineered Air, Marlo Coil, Keco, Fermont, ESSIbuy, UPSI, Radian, TAMSCO,
EEI, PCA, Spacelink and Mobilized Systems and all employees of SEI with an
employment starting date after December 31, 2004. The ESOP provides for a
matching contribution by the Company of no less than 25% of each employee's
contributions up to a maximum of 6% of the employee's earnings. The Company
also makes discretionary annual contributions. All employee and employer
contributions to the ESOP are 100% vested. In addition, the Company
previously sponsored the TAMSCO Tax Deferred Retirement Plan, the Engineered
Environments, Inc. 401(k) Plan, the Prospective Computer Analysts, Inc.
Employee Savings and Retirement Plan, the Spacelink International, LLC
401(k) Plan, and Mobilized Systems, Inc. 401(k) Incentive Savings Plan. The
Company has recorded expense based on contributions to the ESOP, the TAMSCO
plan, the EEI plan, the PCA plan, the Spacelink plan, and the MSI plan for
the years ended October 31, 2005, 2004 and 2003 of $7,173, $4,600 and
$1,989, respectively.

         The Company also has a qualified Employee Stock Purchase Plan
(ESPP), the terms of which allow for qualified employees, as defined, to
purchase the Company's common stock at a price equal to 95% of the closing
price at the beginning of each semi-annual stock purchase period. Prior to
July 1, 2005, the plan allowed plan participants to purchase shares of the
Company's common stock at a price equal to 85% of the lower of the closing
price at the beginning or end of each semi-annual stock purchase period, but
was amended to comply with recently enacted income tax law changes
concerning employer-sponsored stock purchase plans. The Company issued 128,
129 and 81 shares of common stock during the years ended October 31, 2005,
2004 and 2003 pursuant to the ESPP at an average price per share of $31.69,
$22.79 and $20.27, respectively.

NOTE L -- BUSINESS SEGMENT INFORMATION

         Based on its organizational structure, the Company operates in two
business segments: Support Systems and Support Services. The Support Systems
segment designs, engineers and manufactures integrated military electronics
and other military support equipment primarily for the DoD, as well as
related heat transfer and air handling equipment for domestic commercial and
industrial users. Segment products include environmental control systems,
load management and transport systems, power generation, distribution and
conditioning systems, airborne radar systems, reconnaissance, surveillance
and target acquisition systems, chemical and biological protection systems,
petroleum and water distribution systems and other multipurpose military
support equipment. The Support Services segment provides engineering
services, logistics and training services, advanced technology services,
asset protection systems and services, telecommunication systems integration
and information technology services primarily for the DoD. The Support
Services segment also provides certain power generation and distribution
equipment and vehicle armor installation to the DoD.

         Management utilizes more than one measurement and multiple views of
data to measure business segment performance and to allocate resources to
the segments. However, the dominant measurements are consistent with the
Company's Consolidated Financial Statements and, accordingly, are reported
on the same basis herein. Management evaluates the performance of its
business segments and allocates resources to them primarily based on income
from operations, along with cash flows and overall economic returns. The
Company's export net revenues are not significant. All corporate expenses
and assets have been allocated to the segments. In 2005, 2004 and 2003,
approximately, 96%, 94% and 95% of consolidated net revenues were derived
directly or indirectly from the U.S. government.


                                     47


         The following table summarizes the Company's net revenues
attributed to the United States and to foreign countries:

of the purchaser of the product or service.

2005, $13.9 million were located in countries other than the U.S.

NOTE M -- COMMITMENTS AND CONTINGENCIES

         As a government contractor, the Company is continually subject to
audit by various agencies of the U.S. government to determine compliance
with various procurement laws and regulations. As a result of such audits
and as part of normal business operations of the Company, various claims and
charges are asserted against the Company. It is not possible at this time to
predict the outcome of all such actions. However, management is of the
opinion that it has good defenses against such actions and believes that
none of these matters will have a material effect on the consolidated
financial position or the results of operations of the Company.

         Total contractual and contingent obligations as of October 31, 2005
are as follows:



                                                              Payments / Expiration

         While contingent obligations are included in the table above, the
Company does not expect to fund the full amounts indicated for letters of
credit. Lease expense totaled $5.9 million, $5.0 million and $4.2 million
for the years ended October 31, 2005, 2004 and 2003, respectively.

NOTE N -- SEC INVESTIGATION

         In December 2004, the Company was notified by the Enforcement
Division of the SEC of the issuance of a formal order directing a private
investigation captioned In the Matter of Engineered


                                     49


Support Systems, Inc. and that the SEC had issued subpoenas to various
individuals associated with the Company to produce certain documents. The
SEC staff also requested that the Company voluntarily produce certain
documents in connection with the investigation. The subpoenas related to
trading in the Company's stock around the Company's earnings releases in
2003 and the adequacy of certain disclosures made by the Company regarding
related-party transactions in 2002 and 2003 involving insurance policies
placed by the Company through an insurance brokerage firm in which a
director of the Company was a principal at the time of the transactions. On
or about September 23, 2005, the SEC staff contacted the Company's counsel
and advised that it had issued a subpoena directed to the Company and
expanded its investigation to include the Company's disclosure of a November
2004 stop-work order relating to the Company's Deployable Power Generation
and Distribution System program for the U.S. Air Force, and trading in the
Company's stock by certain individuals associated with the Company.

         In connection with the foregoing SEC investigation, the Company and
certain of its directors and officers have provided information and
testimony to the SEC. The Company continues to furnish information requested
by the SEC. The Company is unable to determine at this time either the
timing of the investigation or the impact, if any, which the investigation
could have on the Company or the combined company following the Company's
proposed merger with DRS as explained in Note P.

NOTE O -- STOCK SPLIT

         On April 15, 2005, the Company effected a three-for-two stock split
in the form of a 50% stock dividend. All per share amounts, as well as all
share amounts related to the Company's stock option and stock purchase
plans, have been restated to reflect this stock split.

NOTE P -- MERGER AGREEMENT WITH DRS TECHNOLOGIES, INC.

         On September 21, 2005, the Company and DRS Technologies, Inc. (DRS)
entered into a definitive agreement which provides for the acquisition by
DRS of all of the outstanding common stock of the Company for approximately
$1.9 billion, or $43.00 per share (subject to possible adjustment), through
a combination of cash and DRS common stock. Pending customary regulatory
approvals and other closing conditions, including approval by DRS and
Company shareholders, the transaction is anticipated to close before
March 31, 2006.

net income resulting from revisions, adjustments and changes in estimates
for certain long-term contracts, primarily at the Company's Keco subsidiary.

           REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of
Engineered Support Systems, Inc.:

We have completed an integrated audit of Engineered Support Systems, Inc.'s
2005 consolidated financial statements and of its internal control over
financial reporting as of October 31, 2005 and audits of its 2004 and 2003
consolidated financial statements in accordance with the standards of the
Public Company Accounting Oversight Board (United States). Our opinions,
based on our audits, are presented below.

Consolidated financial statements and financial statement schedule
------------------------------------------------------------------

In our opinion, the consolidated financial statements listed in the
accompanying index present fairly, in all material respects, the financial
position of Engineered Support Systems, Inc. and its subsidiaries at October
31, 2005 and 2004, and the results of their operations and their cash flows
for each of the three years in the period ended October 31, 2005 in
conformity with accounting principles generally accepted in the United
States of America. In addition, in our opinion, the financial statement
schedule listed in the accompanying index presents fairly, in all material
respects, the information set forth therein when read in conjunction with
the related consolidated financial statements. These financial statements
and financial statement schedule are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements and financial statement schedule based on our audits. We
conducted our audits of these statements in accordance with the standards of
the Public Company Accounting Oversight Board (United States). Those
standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit of financial statements includes examining, on a test
basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant
estimates made by management, and evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

Internal control over financial reporting
-----------------------------------------

Also, in our opinion, management's assessment, included in the Report of
Management on Internal Control over Financial Reporting appearing under Item
9A, that the Company maintained effective internal control over financial
reporting as of October 31, 2005 based on criteria established in Internal
Control - Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission (COSO), is fairly stated, in all
material respects, based on those criteria. Furthermore, in our opinion, the
Company maintained, in all material respects, effective internal control
over financial reporting as of October 31, 2005, based on criteria
established in Internal Control - Integrated Framework issued by the COSO.
The Company's management is responsible for maintaining effective internal
control over financial reporting and for its assessment of the effectiveness
of internal control over financial reporting. Our responsibility is to
express opinions on management's assessment and on the effectiveness of the
Company's internal control over financial reporting based on our audit. We
conducted our audit of internal control over financial reporting in
accordance with the standards of the Public Company Accounting Oversight
Board (United States). Those standards require that we plan and perform the
audit to obtain reasonable assurance about whether effective internal
control over financial reporting was maintained in all material respects. An
audit of internal control over financial reporting includes obtaining an
understanding


                                     52


of internal control over financial reporting, evaluating management's
assessment, testing and evaluating the design and operating effectiveness of
internal control, and performing such other procedures as we consider
necessary in the circumstances. We believe that our audit provides a
reasonable basis for our opinions.

A company's internal control over financial reporting is a process designed
to provide reasonable assurance regarding the reliability of financial
reporting and the preparation of financial statements for external purposes
in accordance with generally accepted accounting principles. A company's
internal control over financial reporting includes those policies and
procedures that (i) pertain to the maintenance of records that, in
reasonable detail, accurately and fairly reflect the transactions and
dispositions of the assets of the company; (ii) provide reasonable assurance
that transactions are recorded as necessary to permit preparation of
financial statements in accordance with generally accepted accounting
principles, and that receipts and expenditures of the company are being made
only in accordance with authorizations of management and directors of the
company; and (iii) provide reasonable assurance regarding prevention or
timely detection of unauthorized acquisition, use, or disposition of the
company's assets that could have a material effect on the financial
statements.

Because of its inherent limitations, internal control over financial
reporting may not prevent or detect misstatements. Also, projections of any
evaluation of effectiveness to future periods are subject to the risk that
controls may become inadequate because of changes in conditions, or that the
degree of compliance with the policies or procedures may deteriorate.

As described in the Report of Management on Internal Control over Financial
Reporting appearing under Item 9A, management has excluded certain elements
of the internal control over financial reporting of Spacelink, LLC,
Prospective Computer Analysts Incorporated, and Mobilized Systems, Inc. from
its assessment of the Company's internal control over financial reporting as
of October 31, 2005 because each was acquired by the Company in a purchase
business combination during 2005. Subsequent to the acquisition, certain
elements of the acquired businesses' internal control over financial
reporting and related processes were integrated into the Company's existing
systems and internal control over financial reporting. Those controls that
were not integrated have been excluded from management's assessment of the
effectiveness of internal control of financial reporting as of October 31,
2005. We have also excluded those elements from our audit of internal
control over financial reporting. The combined excluded elements of
Spacelink, LLC, Prospective Computer Analysts Incorporated, and Mobilized
Systems, Inc. represent controls over accounts of approximately 4% of total
assets and 8% of total revenues of the related consolidated financial
statement amounts as of and for the year ended October 31, 2005.

ITEM 9A.   CONTROLS AND PROCEDURES
--------   -----------------------

         ESSI carried out an evaluation, under the supervision and with the
participation of its management, including ESSI's Chief Executive Officer
and Chief Financial Officer, of the effectiveness of the design and
operation of ESSI's disclosure controls and procedures, as defined in Rules
13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as
amended (the "Exchange Act") as of October 31, 2005. Based upon that
evaluation, ESSI's Chief Executive Officer and Chief Financial Officer
concluded that ESSI's disclosure controls and procedures are effective.
Disclosure controls and procedures are controls and procedures that are
designed to ensure that information required to be disclosed in ESSI's
reports filed or submitted under the Exchange Act is recorded, processed,
summarized and reported within the time periods specified in the Securities
and Exchange Commission's rules and forms.

         There have been no changes in ESSI's internal control over
financial reporting (as defined in Rule 13a-15(f) under the Exchange Act)
during the fiscal quarter ended October 31, 2005 that have materially
affected, or are reasonably likely to materially affect, ESSI's internal
control over financial reporting.

REPORT OF MANAGEMENT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

         The management of ESSI is responsible for establishing and
maintaining adequate internal control over financial reporting. Internal
control over financial reporting is a process designed to provide reasonable
assurance regarding the reliability of ESSI's financial reporting for
external purposes in accordance with accounting principles generally
accepted in the United States of America. Internal control over financial
reporting includes maintaining records that in reasonable detail accurately
and fairly reflect ESSI's transactions and dispositions of assets of the
Company; providing reasonable assurance that transactions are recorded as
necessary for preparation of our financial statements in accordance with
generally accepted accounting principles; providing reasonable assurance
that receipts and expenditures of company assets are made in accordance with
management authorization; and providing reasonable assurance that
unauthorized acquisition, use or disposition of company assets that could
have a material effect on our financial statements would be prevented or
detected on a timely basis.

         Management conducted an evaluation of the effectiveness of ESSI's
internal control over financial reporting based on the framework and
criteria established in Internal Control -- Integrated Framework, issued by
the Committee of Sponsoring Organizations of the Treadway Commission. This
evaluation included review of the documentation of controls, evaluation of
the design effectiveness of controls, testing of the operating effectiveness
of controls and a conclusion on this evaluation.

         Based on this evaluation, management concluded that ESSI's internal
control over financial reporting was effective as of October 31, 2005.
Management's assessment of the effectiveness of ESSI's internal control over
financial reporting as of October 31, 2005 has been audited by
PricewaterhouseCoopers LLP, an independent registered public accounting
firm, as stated in their report which is included in Item 8 of this Annual
Report on Form 10-K.

         Management has excluded certain elements of the internal control
over financial reporting of Spacelink, LLC, Prospective Computer Analysts
Incorporated, and Mobilized Systems, Inc. from its assessment of the
Company's internal control over financial reporting as of October 31, 2005
because each was acquired by the Company in a purchase business combination
during 2005. Subsequent to the acquisition, certain elements of the acquired
businesses' internal control over financial reporting and related processes
were integrated into the Company's existing systems and internal control
over financial reporting. Those controls that were not integrated have been
excluded from management's assessment of the effectiveness of internal
control of financial reporting as of October 31, 2005. The combined excluded
elements of Spacelink, LLC, Prospective Computer Analysts Incorporated, and
Mobilized Systems, Inc. represent controls over accounts of approximately 4%
of total assets and 8% of total revenues of the related consolidated
financial statement amounts as of and for the year ended October 31, 2005.

RETIREMENT PLANS

         ESSI maintains a defined benefit pension plan providing retirement
benefits for certain employees, including officers. Contributions are made
on an actuarial group basis, and no specific amount of contributions is set
aside for any individual participant. The following table sets forth the
approximate annual pension benefit based on years of service and
compensation and reflects dollar limitations under the Internal Revenue
Code, as amended, which limits the annual benefits which may be paid from a
tax-qualified retirement plan.
