                              PART I
ITEM 1.   BUSINESS
- -------   --------

     Engineered Support Systems, Inc. is a holding company for four
wholly-owned subsidiaries: Engineered Air Systems, Inc. (Engineered
Air), Keco Industries, Inc. (Keco), Engineered Coil Company, d/b/a Marlo
Coil (Marlo Coil) and Engineered Specialty Plastics, Inc. (ESP). 
Engineered Support Systems, Inc. and its subsidiaries (Company) is a
leading designer and manufacturer of military support equipment and
related products for the United States armed forces.  The Company also
manufactures specialized commercial and industrial air handling
equipment, as well as injection molded specialty and custom plastic
products.

     Engineered Air and Keco are military ground support equipment
contractors which specialize in designing, marketing and manufacturing
chemical and biological defense systems, environmental control systems,
petroleum and water systems, containerized systems and general ground
support equipment.  This equipment is designed to be used in any
location where U.S. forces may be deployed.  It is designed for rapid
deployment and multi-purpose use in remote locations.  Substantially all
of the revenues generated by Engineered Air and Keco are derived from
the sale of equipment to the Department of Defense (DoD) and defense
contractors.  Marlo Coil is a manufacturer of heat transfer and air
movement equipment, which is generally produced to customer
specifications.  Marlo Coil's products, principally coils and air
handling units, are sold to the U.S. Navy through prime contractors as
well as to commercial and industrial customers.  ESP is a manufacturer
of injection molded plastic products used primarily in consumer goods
such as housewares, storage containers, components for computer
terminals, and communication equipment.  In addition to these products,
ESP also produces Lifetime Faucets, a proprietary line of plastic
faucets.

     Engineered Air was incorporated under the laws of the State of
Missouri on December 24, 1981, and acquired the assets of the Defense
Systems Division of Allis-Chalmers Corporation on March 30, 1982.  The
Company 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 the Company's
founders.  The Company purchased the remaining one-third of the common
stock of Engineered Air in January 1984, effective as of November 1,
1983.  The Company became a publicly owned corporation on August 21,
1985.  On March 9, 1993, the Company purchased all of the outstanding
stock of Associated Products, Inc. (subsequently changed to Engineered
Specialty Plastics, Inc.).  Effective February 1, 1998, Engineered Coil
Company acquired substantially all of the net assets of Nuclear Cooling,
Inc., d/b/a Marlo Coil.  On June 24, 1998, the Company purchased all of
the outstanding common stock of Keco.

PRODUCTS

     MILITARY PRODUCTS.  The Company provides products to U.S. armed
forces in five general categories:

Chemical and biological defense systems.  The Company engineers and
manufactures products and systems which are designed to protect forward
deployed military units from the effects of chemical or biological
weapons.  These include:

      * Chemical and Biological Protected Shelter System (CBPSS), 
        which is a contamination-free, environmentally-controlled
        work area that is used as a mobile field medical facility. 
        It is a specially designed system centered around a soft-
        walled tent supported by inflated columns of air.  The tent
        is connected to and carried by a High Mobility Multi-Purpose
        Wheeled Vehicle, more commonly known as a "Humvee."  The
        CBPSS permits medical specialists to treat soldiers while
        deployed in an area exposed to chemical or biological
        contamination.

      * Micro-Climatic Conditioning System (MCS), which is an on-board
        air-filtration unit for the Paladin tank and is designed to
        enhance survivability for the Paladin crews by providing air
        filtration of chemical and biological materials, ventilation
        and cooling.

                                   2<PAGE>
<PAGE>

      * Sanator/M-17, which is a lightweight chemical and biological 
        decontamination system used to decontaminate equipment in
        the field utilizing a hot water and detergent spray mixture.

Environmental Control Systems.  The Company engineers and manufactures
systems which regulate and modify environmental conditions in military
enclosures, aircraft, ships and vehicles.  These include:

      * Field Deployable Environmental Control Unit (FDECU), which 
        is a field deployable heat pump for use in cooling, heating,
        dehumidifying, filtering and circulating air for portable
        shelters, tents and vans.  The unit is adaptable to
        chemically and biologically contaminated areas.

      * Chemically/Biologically Hardened Air Management Plant 
        (CHAMP), which is an air management system providing
        cooling, heating, standby electrical power and pressurized
        filtered air protection against chemical and biological
        agents and was initially designed for use by the U.S. Air
        Force in chemically hardened, air transportable hospitals. 
        These units consolidate a generator, blowers, filters and
        environmental control elements into a single system,
        reducing transportation weight and size by 80%.  This unit
        can be operated by either commercial power or a self-
        contained diesel engine and enable medical staff and
        patients to reduce infection and continue emergency
        operations in a contaminated environment.

      * Flight Line Air Conditioners, which are used to cool 
        aircraft avionics and electronics systems during pre-flight
        and post-flight checkouts and repairs.  Among these units
        are the largest air conditioning units ever built for the
        U.S. Air Force employing state-of-the-art technology and
        utilizing R-134 refrigerant, which is ozone friendly and
        environmentally safe.  This unit supports operations of
        various military aircraft including: the B-1B and B-2
        bombers; the C-5, C-130 and C-141 transports; all fighter
        aircraft; and the Talon I and Talon II gunships.

      * Army Space Heaters (ASH), which provide automatic, remote or 
        normal temperature-controlled heating to meet the needs of
        personnel and equipment in shelters, vans, hospitals and
        other enclosed areas.  Most recently, the ASH has been
        shipped overseas to provide warmth for U.S. military personnel
        in the extreme winter conditions of Bosnia.  The unit is 
        designed to be adapted to chemically and biologically 
        contaminated environments.

      * Fan Coil Units and Assemblies, which are used to meet air 
        conditioning and heating needs aboard U.S. Navy ships and
        Military Sealift and Coast Guard vessels, including ships of
        the Arleigh Burke Class Aegis destroyers, Ticonderoga Class
        Aegis cruisers, Seawolf and NSSN attack submarines, San
        Antonio Class and LHD amphibious assault ships and Nimitz
        Class and CVN-77 aircraft carriers.

Petroleum and water systems.  The Company manufactures systems for
pumping, storing and testing water and petroleum.  These include:

      * Petroleum storage, distribution and refueling equipment, 
        which is used in support of remotely located field equipment
        and weapon systems.  These systems include the Inland
        Petroleum Distribution System, which is a portable pipeline,
        storage and distribution system set up to transport fuel up
        to 270 miles over various terrains.

      * Water distribution and storage systems with trailer mounted 
        pumps and collapsible tanks.

      * Airmobile and Semi-trailer Mounted Petroleum Test 
        Laboratories, which are used for testing the purity of fuels
        in the field.

      * Reverse Osmosis Water Purification Units (ROWPU), which are 
        durable and mobile water purification systems and which
        provide safe drinking water, primarily to forces in the
        field with the capacity to filter highly contaminated water.

                                   3<PAGE>
<PAGE>
Containerized systems.  The Company manufactures specially designed
container systems.  These include:

      * Quadcon containers, which are transportable and connectable 
        containers for multi-use storage or transportation of bulk
        products.

      * Refrigerated containers, which are used to transport 
        perishable and frozen foods.

General ground support equipment.  The Company also manufactures a range
of general ground support equipment.  These include:

      * Deployable Fire Protection Systems, which are trailer 
        mounted units designed to apply 500 gallons of fire-fighting
        foam in one minute for use in areas where fuel is being
        distributed, such as airfields.  The system automatically
        detects fires across a 120 degree vision area after being
        deployed.

      * Portable Field Latrines, Laundry, Shower and Shave 
        Facilities, which are used by forward deployable combat
        units.

      COMMERCIAL AND INDUSTRIAL PRODUCTS.  The Company has been 
able to capitalize on its naval contracting experience to design
and manufacture a broad range of air handling and heat transfer
equipment for commercial and industrial applications.  Such
applications include commercial and institutional buildings,
civilian marine applications, and pharmaceutical, semiconductor
and telecommunications clean rooms.

      The Company engineers and manufactures injection molded 
custom and specialty plastic products for consumer and industrial
markets.  These products include housewares, food handling totes,
storage containers, medical devices, automotive equipment, plastic
components for computer terminals and telecommunications equipment
and a proprietary line of nonmetallic faucets.

ENGINEERING AND DESIGN

      The Company employs approximately 70 people engaged in the 
design and development of new products and the improvement of
existing products.  Essentially all of these development activities 
are conducted pursuant to, and funded by, DoD contracts in response 
to designated performance specifications.  The Company believes 
that its engineering expertise gives it a significant advantage 
over smaller competitors who do not have such capabilities.  The 
Company's expenditures on research and development were insignificant 
during the three-year period ended October 31, 1998.

      The Company's engineering capabilities include expertise in 
thermodynamics, air flow, liquid pumping, stress analysis, liquid
fuel combustion, dynamic and climatic environmental engineering,
biological and chemical decontamination, non-pyrotechnic smoke
generation, and filtration of chemically and biologically
contaminated air.

      The Company's design and development of ground support 
equipment are enhanced by a computer-aided design and manufacturing 
(CAD/CAM) system.  This system is used by engineers and draftsmen 
to design complex products and component parts in three-dimensional 
view, and minimizes the need for time-consuming manual methods of 
prototype development.  The Company's engineering staff and CAD/CAM 
system provide it with the ability to adapt its production process 
to new product needs on a timely basis.

      The Company maintains extensive laboratory facilities used 
for supporting engineering development and production operations. 
These include test facilities for measurement of product performance 
from -65 degrees to +140 degrees Fahrenheit and completely equipped 
prototype facilities.  The Company also has the capability to provide 
complete technical data support for the products it manufactures.  
This includes integrated logistics support, spare parts provisioning 
and preparation of technical manuals.

                                   4<PAGE>

MARKETING

      The Company's marketing of military equipment focuses, in part,
on determining the current and future needs of the DoD for support
equipment.  To identify those needs, the Company gathers information
from primary sources such as the DoD budget and its supporting
documents, and military requirement documents such as the Air Force's
Statement of Need, the Navy's Operational Requirements and the Army's
Required Operational Capability, along with direct interface with its
customers.  The Company analyzes this data through an established new
business opportunity procedure and then determines whether or not to bid
on specific projects based upon determinations of potential
profitability and the likelihood of being awarded the contract.

      Sales of custom commercial, industrial and marine air handling
units and coils are effected both directly and through sales
representatives located primarily in the United States, parts of Canada,
and Puerto Rico.  Generally, the customers' engineers and contractors
provide the required specifications and performance data.  The Company,
in turn, designs and manufactures the equipment to meet the specified
criteria with a focus on quality, value and service.  Customers are
typically large and well established companies which require equipment
for industrial and other specialized applications with specifications
far more exacting than those that would normally be supplied for comfort
cooling and heating.  The pharmaceutical, telecommunications and
healthcare industries represent a significant portion of current 
sales volume.

      Principal customers for injection molded custom and specialty
plastic products include large, well-established producers of consumer
and industrial products.  Sales of injection molded plastic products are
effected both directly and through sales representatives.  Customers
typically submit sample parts and drawings to the Company for quotations.
Contracts can typically be canceled on 30 days notice.  A significant 
portion of the Company's sales of injection molded plastics products 
are of storage containers.  The Company anticipates that container sales 
will remain strong as it is in geographic proximity to several large
purchasers of these products, including companies within the housewares 
and poultry industries which the Company believes is an important 
consideration in this market.  The Company also anticipates that sales 
for its injection molded plastic products will continue to be strong
within the office equipment market.  Injection molded parts for computer 
terminals and telecommunications equipment represent a significant 
portion of sales volume.  However, the Company is capable of producing
a wide variety of injection molded plastic products, including
automotive parts, medical equipment, switching equipment, electrical
appliances and most small electronic devices.  The Company's sales of
its proprietary line of kitchen and lavatory faucets are effected
primarily through sales representatives, and marketing efforts focus
on service and price.

MANUFACTURING AND PROCUREMENT

      The Company manufactures certain components for its products and
systems including fabricated metal cabinets, control panels and frames. 
The Company is equipped to bend, cut, drill and weld sheet metal. 
However, a significant portion of component parts and materials for the
products manufactured by the Company are purchased from third party
suppliers.  Management believes that the materials and services the
Company requires are readily available through competitive sources and
that the Company is not dependent upon any one subcontractor or vendor. 
Two of the Company's facilities have received ISO 9000 certification and
the Company is qualified by the U.S. government to the military control
specifications MIL-I-45208 and MIL-Q-9858, which apply to most of the
Company's government contracts currently in progress.  The Company
intends to seek ISO 9000 certification for at least one of its other
facilities.

      The Company engineers and manufactures injection molded custom and
specialty plastic products for consumer and industrial markets.  These
products include housewares, food handling totes, storage containers,
medical devices, automotive equipment, plastic components for computer
terminals and telecommunications equipment and a proprietary line of
nonmetallic faucets.  Approximately one third of the Company's sales of
injection molded plastic products are generated by products which are
proprietary.  The Company's injection

                                   5
<PAGE>
<PAGE>

molded plastic manufacturing operations are vertically integrated, 
with the facilities to both mold and finish plastic to exacting
specifications.  The Company operates 33 injection molding machines
ranging in size from 45 to 2,200 tons of clamp pressure.  The Company
believes that its vertical integration, range of machine size and higher
pressure molding capacity provide it with a competitive advantage within
the geographic market it serves.

      Material handling capacity for injection molded plastic products
is achieved through five silos with a combined capacity exceeding
200,000 pounds, a central vacuum loading system, blend mixers and
computer integrated manufacturing control software.  Finishing equipment
includes a 650 foot paint conveyor, 20 paint spray booths, drying ovens,
hot stamp machines, silk screen machines, a 150 foot motorized assembly
line and sonic welders.  The Company subcontracts the assembly and
packaging of Lifetime Faucets to an outside vendor.

GOVERNMENT CONTRACTING

      The Company's government contracts are obtained through the DoD
procurement process as governed by the Federal Acquisition Regulations
and related agency supplements, and are typically fixed-price contracts. 
This means that the price is agreed upon before the contract is awarded
and the Company assumes complete responsibility for any difference
between estimated and actual costs.

      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 thereto, to
determine whether the Company furnished the U.S. government with
complete, accurate and current cost or pricing data as defined by the
Negotiations Act.  In the event the Company 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 typically contain terms permitting the
contract to be terminated at the convenience of the U.S. government.  In
the event of such termination, the Company 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 may also terminate
contracts for cause if the Company fails to perform in strict accordance
with contract terms.  The Company has never had a contract terminated by
the U.S. government for failure to perform in accordance with contract
terms.  Termination of, or elimination of appropriation for, a
significant government contract could have a material adverse effect on
the Company'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, the
Company would be entitled to reimbursement of all allowable and
allocable costs incurred in making the change plus a reasonable profit.

      The U.S. government typically finances a substantial portion of
the Company's contract costs through progress payments.  The Company
historically received progress payments in accordance with DoD contract
terms for "small business" concerns.  These terms provide progress
payments at a specified rate applied on the basis of costs incurred
while progress payments for concerns other than small business provide
for payment based on costs actually paid at a rate that is 15% lower
than that paid to small businesses.  The Marlo Coil and Keco
acquisitions have caused the Company to exceed certain thresholds
relating to small business qualification, and the Company will therefore
qualify as a small business only for specific government contracting
purposes.  The Company is, however, reducing its emphasis on small
business qualification for purposes of future government work.

                                   6<PAGE>
<PAGE>

PATENTS

      The Company owns various patents in connection with its equipment
supplied to the DoD with expiration dates extending through February
2002.  From time to time, the Company develops proprietary information
and trade secrets regarding the design and manufacture of various
products.

      The Company also holds a patent for a reversible faucet cartridge. 
The benefit of the reversing feature is that by turning the cartridge
one-half revolution the user achieves that same result as though the
washer had been replaced to stop a leaking faucet.  This patent expires
in October 2002.

      The Company considers its proprietary information and patents to
be valuable assets.  However, the Company's business is not materially
dependent on patent protection.

COMPETITION

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

DEFENSE BACKLOG

      The Company records its defense backlog as either funded backlog
or government options.  The Company's funded backlog as of October 31,
1998 was approximately $80.8 million.  The Company's funded backlog is
subject to fluctuations and is not necessarily indicative of future
sales.  Funded backlog represents products the government has committed
by contract to purchase from the Company.  Government options include
products the government has the option to purchase under contract with
the Company, including, with respect to contracts which include a
maximum amount purchasable by the government thereunder, such maximum
amount, and with respect to contracts without a specified maximum
amount, the Company's estimate of the amount it expects the government
to purchase using the government's Best Estimated Quantity (BEQ) as a
guide where a BEQ is specified.  There are no commitments by the
government to purchase products included in government options and there
can be no assurance that any or all amounts included therein will
generate revenue for the Company.  Moreover, cancellations of purchase
orders or reductions of product quantities in existing contracts could
substantially reduce the Company's funded backlog and, consequently,
future net revenues.  Failure of the Company to replace canceled or
reduced backlog, whether funded backlog or government options, could
have a material adverse effect on the Company's business, financial
condition and results of operations in subsequent periods.

EMPLOYEES

     As of October 31, 1998, the Company employed 841 persons, of 
which 617 were engaged in manufacturing activities, 70 in engineering
activities, and 154 in office administration and management functions.
Approximately 95 employees are represented by Lodge 1012 of the
International Brotherhood of Boilermakers, Iron Ship Builders, Blacksmiths,
Forgers and Helpers (AFL-CIO) under a collective bargaining agreement which
expired October 31, 1998. Although negotiations continue, the date of any
new agreement with these employees is uncertain at this time. The Company is
confident that it can retain a capable workforce regardless of the outcome of
these negotiations.

     The Company considers its overall employee relations to be satisfactory.

/ /LETTER TO THE SHAREHOLDERS
 
Dear Shareholder:
 
  1998 was an exciting year for Engineered Support Systems, Inc. The Company's
long-standing defense subsidiary substantially completed development on two
major contracts. A strategic acquisition secured the talents and facilities of
this subsidiary's heretofore most significant competitor. A second acquisition
allowed the Company to broaden its product offerings to the U.S. Navy, a
military branch not previously served by either the existing or acquired
defense operations. And finally, the Company's commercial plastics subsidiary
turned in another outstanding performance. As in each of the prior two years,
the Company's net revenues, net income and earnings per share increased to
record levels. However, the most exciting part of our 1998 results lies in the
fact that the Company enters 1999 in a stronger financial, operating and
strategic position than at any point in our history.
 
SUMMARY OF 1998
 
  The Company reported net income of $5,789,000, or $1.16 per diluted common
share, on revenues of $97.0 million. This compares with net income of
$4,639,000, or $.94 per diluted common share, on revenues of $88.6 million in
1997. (All per share amounts give effect to a 3-for-2 stock split completed by
the Company on June 26, 1998).
 
  Net revenues and operating income from military support and related
industrial/commercial equipment increased 9% and 26%, respectively, from the
prior year. These results represent the operations of three of the Company's
four subsidiaries: Engineered Air Systems, Inc. (Engineered Air), Keco
Industries, Inc. (Keco) and Engineered Coil Company, d/b/a Marlo Coil (Marlo
Coil). Much of Engineered Air's efforts in 1998 were focused on the development
of two key contracts: the Chemical and Biological Protected Shelter System 
(CBPSS) and the Chemically/Biologically Hardened Air Management Plant (CHAMP).
These two programs represent $116 million, or 29%, of the Company's total
funded and unfunded backlog of defense orders at October 31, 1998. Both 
contracts enter full-scale production in 1999. In addition, we believe that
significant market potential exists for chemical and biological defense
systems and related products, such as the CBPSS and CHAMP, because of the
growing awareness of the threat of chemical and biological warfare and
terrorism.
 
  In February 1998, Engineered Coil Company, a wholly-owned subsidiary of the
Company, acquired substantially all of the net assets of Nuclear Cooling, Inc.,
d/b/a Marlo Coil, a manufacturer of heat transfer and air movement equipment
used by the U.S. Navy, as well as industrial and commercial customers. Acquired
for $25.4 million, Marlo Coil generated net revenues of $21.7 million for the
nine months of 1998 during which it was owned by the Company. Marlo Coil
provides not only solid and consistent operating results, but also the
opportunity for the Company to broaden its product offerings to the U.S. Navy,
Military Sealift Command and Coast Guard, customers not currently served by the
Company's other subsidiaries.

  Keco was acquired for $26.7 million in June 1998, thereby enhancing the
Company's position as a significant supplier of ground support equipment to the
Department of Defense (DoD). Keco's net revenues totaled $14.8 million for the
four-month period of 1998 during which it was owned by the Company. In addition
to significant operational synergies, the Keco acquisition also brings with it
the largest contract in the Company's history. The contract for Field
Deployable Environmental Control Units (FDECU) entered production in the fourth
quarter of 1998 and represents $147 million, or 37%, of the Company's total
funded and unfunded backlog of defense orders at October 31, 1998.

  While the acquisitions of Marlo Coil and of Keco have been immediately
accretive to earnings per share, we believe that both transactions add
significant long-term value to our shareholders. Because of the DoD's
continuing emphasis on "best value buying", whereby production quality and
engineering/design capabilities are emphasized, we believe the Company will
continue to be recognized as a preferred supplier during contract procurement
particularly in light of the added capabilities and streamlined cost structures
resulting from the two acquisitions.

  Net revenues and operating income from the custom molded plastic products
operations of Engineered Specialty Plastics, Inc. (ESP) increased 12% and 53%,
respectively, to record levels in 1998. The significant earnings gain is
primarily a result of increased capacity utilization. During the year, ESP
invested $1.0 million in new equipment, primarily for two molding machines with
1200 and 610 tons of clamp pressure, respectively. The additional machines were
added to handle strong customer demand, which the Company anticipates will
continue through 1999 and beyond.
 
BALANCE SHEET RESHAPED
 
  In order to finance the Marlo Coil and Keco acquisitions, the Company amended
its existing bank credit agreement in March 1998 to provide a $45.0 million
term loan and a $10.0 million revolving credit facility. The amended agreement
provides for a more favorable interest rate and for a five-year repayment
schedule on the term loan. As of October 31, 1998, the Company had a term loan
balance of $44.0 million after initiating principal payments in September, no
borrowings under the revolving credit facility and a cash balance of $5.8
million. Although total debt, including the ESOP guaranteed bank loan,
represented 48.5% of total assets at October 31, 1998 versus 5.8% in the prior
year, the Company believes that operational cash flows will be more than
sufficient to service the existing debt. In this regard, the Company generated
free cash flow (net income plus non-cash items less capital expenditures) of
$7.4 million in 1998 compared to $4.2 million in 1997. Free cash flow is
expected to increase significantly in future years as operational results for
Marlo Coil and Keco are included for the entire period, and as defense
production levels increase primarily as a result of the FDECU, CBPSS and CHAMP
contracts.
<PAGE>
 Working capital increased to $18.2 million at October 31, 1998 from $11.6
million in the prior year and the current ratio remained strong at 1.83 to 1 at
October 31, 1998. A portion of the working capital increase was due to $2.6
million of proceeds generated from the sale of property, plant and equipment,
primarily a facility previously leased to an unrelated third party. (An
after-tax gain on the sale of these assets totaling $0.5 million, or $.11 per
share, is included in 1998 net income). Total shareholders' equity increased to
$30.2 million, or $6.22 per share, at October 31, 1998 compared to $23.7
million, or $4.98 per share, at October 31, 1997.
 
ACQUISITION STRATEGY
 
  We continue to believe that significant opportunities exist for consolidation
within the defense industry. The acquisitions of Marlo Coil and Keco have
allowed the Company to broaden our product lines and diversify our existing
customer base, while realizing cost savings from process improvements, greater
purchasing power and the elimination of duplicative costs. We will continue to
pursue strategic acquisitions within the defense industry. However, any
acquisition consummated by the Company must provide both accretion to earnings
per share and long-term shareholder value.

  I would like to congratulate all of our employees and directors for another
outstanding performance in 1998. Your efforts have rewarded our shareholders
with an average annual return of 50.9% for the seven-year period ended December
31, 1998. I look forward to the challenge of continuing to provide significant
shareholder value in the years to come.
 
Sincerely,
 
/s/ Michael F. Shanahan Sr.

/ /MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS
 
RECENT DEVELOPMENTS
 
  The Company has grown substantially in recent years as a result of both
internal growth and of two significant acquisitions in 1998. Effective February
1, 1998, the Company acquired substantially all of the net assets of Nuclear
Cooling, Inc., d/b/a Marlo Coil (Marlo Coil), a manufacturer of heat transfer
and air movement equipment, from an investor group for approximately $25.4
million. On June 24, 1998, the Company purchased all of the outstanding common
stock of Keco Industries, Inc. (Keco), a manufacturer of military ground
support equipment, from an investor group for approximately $26.7 million.
These two acquisitions were accounted for as purchase transactions. After
allocating the respective purchase price to the fair value of all identifiable
tangible and intangible assets, goodwill of $24.5 million was recognized and is
being amortized over an estimated life of 25 years. On a pro forma basis, the
Company's net revenues and net income for 1998 were $130.4 million and $6.1
million, respectively, compared to actual net revenues and net income for 1998
of $97.0 million and $5.8 million, respectively. Pro forma 1998 net revenues
and net income represent compound annual increases of 26.5% and 35.2%,
respectively, from actual 1996 net revenues of $81.5 million and net income of
$3.3 million.

  The discussion set forth below analyzes certain factors and trends related to
the financial results for each of the three years ended October 31, 1998, 1997
and 1996. This discussion should be read in conjunction with the Consolidated
Financial Statements and Notes to the Consolidated Financial Statements.
 
1998 COMPARED TO 1997
 
  Net revenues increased 9.5% in 1998 to $97.0 million from $88.6 million in
1997. Net revenues from military support and related industrial/commercial
equipment increased by $5.5 million in 1998 to $69.9 million from $64.4 million
in 1997. This increase was due to an additional $21.7 million of net revenues
generated by Marlo Coil during nine months of operations subsequent to its
acquisition and an additional $14.8 million of net revenues generated by Keco
during four months of operations subsequent to its acquisition. Engineered Air
Systems, Inc. (Engineered Air) experienced a decrease of $31.0 million in net
revenues due primarily to the fact that several significant Department of
Defense (DoD) contracts completed, or were nearing completion of, their
production cycles, including those for C-5/MA-3D Flight Line Air Conditioners,
Aviation Ground Power Units (AGPU), Revetment Kits and Harvest Falcon Water
Distribution Systems. Although several major contracts, primarily the
Chemical/Biological Protected Shelter System (CBPSS), the
Chemically/Biologically Hardened Air Management Plant (CHAMP) and the Field
Deployable Environmental Control Units (FDECU), underwent significant
development efforts during 1998, substantial revenues derived from the
production phase of the contracts will not begin until 1999. Net revenues from
sales of custom molded plastic products increased $2.9 million to $27.1 million
in 1998 from $24.2 million in 1997.
 
  Gross profit for 1998 increased 53.4% to $22.6 million (23.3% of net
revenues) from $14.8 million (16.7% of net revenues) in 1997. The increase in
gross profit was a result of higher net revenues and gross margins at
Engineered Specialty Plastics, Inc. (ESP) and of the additions of Keco and
Marlo Coil, net of a decrease in gross profit at Engineered Air resulting from
a significant decrease in net revenues. The increase in gross margins was a
result of higher margins within the Company's historical operations (Engineered
Air and ESP) due to a more profitable mix of contracts and products, and of the
addition of Marlo Coil which generated gross margins above those provided by
the Company's historical operations.
 
  Selling, general and administrative expense increased by $5.3 million to
$12.4 million (12.8% of net revenues) in 1998 from $7.1 million (8.0% of net
revenues) in 1997. This increase was due to the addition of selling, general
and administrative expense generated by Marlo Coil and Keco, including
additional goodwill amortization of $0.6 million.
 
  Interest expense increased by $1.5 million to $1.8 million in 1998 as a
result of term debt incurred in conjunction with the Marlo Coil and Keco
acquisitions. Interest income was $0.3 million in both 1998 and 1997.
<PAGE>
 
  In 1998, the Company realized a $0.9 million gain primarily related to the
sale of a facility previously leased to an unrelated third party. Proceeds from
the sale of all property, plant and equipment totaled $2.6 million.
 
  The effective income tax rate for 1998 and 1997 was 40.0% resulting in total
tax expense of $3.9 million in 1998 and $3.1 million in 1997. As a result of
the foregoing, the net income of the Company increased 24.8% to $5.8 million
(6.0% of net revenues) in 1998
 
                                                                          3 / /

from $4.6 million (5.2% of net revenues) in 1997.
 
1997 COMPARED TO 1996
 
  Net revenues in 1997 increased by 8.7% to $88.6 million from $81.5 million in
1996. Net revenues from military support equipment increased by $5.2 million to
$64.4 million in 1997 from $59.2 million in 1996, primarily as a result of
higher revenues generated from the AGPU contract. Net revenues from sales of
custom molded plastic products increased by $1.9 million to $24.2 million in
1997 from $22.3 million for 1996. The increase from sales of custom molded
plastic products was achieved in spite of reduced shipments of houseware
products in the fourth quarter of 1997 resulting from reduced orders from the
Company's largest custom molded plastics customer.
 
  Gross profit in 1997 increased by 18.9% to $14.8 million (16.7% of net
revenues) from $12.4 million (15.2% of net revenues) in 1996. These increases
are primarily due to significantly higher margins from sales of custom molded
plastic products resulting primarily from increased capacity utilization.
 
  Selling, general and administrative expense increased by $0.6 million to $7.1
million (8.0% of net revenues) in 1997 from $6.5 million (7.9% of net revenues)
in 1996. This increase was consistent with the growth in the Company's net
revenues.
 
  Because of strong operational cash flow in 1997, the Company was able to
reduce total debt (excluding the ESOP guaranteed bank loan) from $2.7 million
at October 31, 1996 to $1.3 million at October 31, 1997 and to increase cash
and cash equivalents from $1.4 million at October 31, 1996 to $8.3 million at
October 31, 1998. As a result, interest expense decreased $0.3 million and
interest income increased $0.2 million in 1997.
 
  The effective income tax rate for 1997 and 1996 was 40.0% resulting in total
tax expense of $3.1 million in 1997 and $2.2 million in 1996. As a result of
the foregoing, the net income of the Company increased by 40.0% to $4.6 million
(5.2% of net revenues) for 1997 from $3.3 million (4.1% of net revenues) in
1996.
 
OUTLOOK FOR 1999 AND FUTURE YEARS
 
  Primarily due to the acquisitions of Keco and Marlo Coil, the Company's
funded backlog of defense orders increased to $80.8 million at October 31, 1998
from $44.1 million at October 31, 1997. In addition, government options on
existing defense contracts (unfunded backlog) increased to $319.6 million at
October 31, 1998 from $155.0 million at October 31, 1997. The Company expects
the majority of these options to be converted into funded backlog.
 
  The Company anticipates that revenues and net income will increase in 1999.
These increases will be a result of the inclusion of Keco and Marlo Coil
operating results for the entire period, as well as the transition of several
major contracts from development to the production phase. The Company will
derive the most significant portion of its 1999 defense revenues from contracts
for the FDECU, B-1B Air Conditioners, the CHAMP, Army Space Heaters and the
CBPSS. The FDECU, CBPSS and CHAMP contracts represent $262.2 million, or 65%,
of the Company's total funded and unfunded backlog of defense orders at October
31, 1998 and, therefore, provide a significant base of revenues through their
respective contract lives.
 
  ESP once again generated record levels of net revenues and earnings in 1998.
The Company anticipates that ESP's 1999 results will equal or exceed those
posted in 1998, and believes that significant growth potential remains within
both current and untapped markets.
 
  The Company believes that significant opportunities continue to exist for
acquisitions within the defense industry. Although the Company believes an
acquisition may occur in 1999, any such transaction must be accretive to
earnings and must provide long-term value to our shareholders.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  In March 1998, the Company restated and amended its credit agreement to
provide a $45.0 million term loan to finance the acquisitions of Marlo Coil
and Keco and to provide a $10.0 million revolving credit facility. The Company
purchased Marlo Coil, net of cash acquired, for $25.3 million and purchased
Keco, net of cash acquired, for $24.1 million. The Company's primary sources
of short-term financing are from cost reimbursements under contracts with the
U.S. government via receipt of progress payments, billings for delivered
products and borrowings under the revolving line of credit. As of October 31,
1998, the Company had no borrowings against the revolving line of credit and
had a cash balance of $5.8 million.
 
  The Company's working capital needs are generally funded through cash flow
from operations and the revolving line of credit. On October 31, 1998, the
Company's working capital and ratio of current assets to current liabilities
were $18.2 million and 1.83 to 1 as compared with $11.6 million and 2.34 to 1 a
year ago. The Company generated $5.4 million and $10.7 million in cash flow
from operations in 1998 and 1997, respectively, which was used, in part, to
finance investment in property, plant and equipment of $1.3 million and $2.0
million, respectively, and treasury stock purchases of $0.8 million and $1.0
million, respectively. In addition, $2.6 million of proceeds were generated in
1998 from the sales of a facility previously leased to an unrelated third party
and of machinery and equipment. (Related income taxes on these sales
approximated $0.3 million). $1.3 million of cash was also provided in 1998 from
the exercise of stock options.
 
  The Company anticipates that capital expenditures in 1999 should not exceed
$2.0 million. Management believes that cash flow generated from operations,
together with the available line of credit, will provide the necessary
resources to meet the needs of the Company in the foreseeable future.
 
INFLATION
 
  Since substantially all of the Company'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, the Company's volume purchasing and forward purchasing
policies serve to limit the effects of inflation. The Company considers
potential inflation in preparation of contract proposals and bids. The
Company's commercial and industrial products as manufactured and sold by Marlo
Coil and ESP are predominantly custom-made. Therefore the impact of inflation
on operating results is typically not significant. The Company 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 the Company's
operations.
 
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS
 
  The Financial Accounting Standards Board (FASB) issued Statement of Financial
Accounting Standards No. 130, "Reporting Comprehensive Income" (SFAS 130), and
Statement of Financial Accounting Standards No. 131, "Disclosures about
Segments of an Enterprise and Related Information" (SFAS 131), in June 1997,
and Statement of Financial Accounting Standards No. 132, "Employers'
Disclosures about Pension and Other Postretirement Benefits" (SFAS 132), in
February 1998. SFAS 130 establishes standards for the reporting and display of
the Company's components of comprehensive income in the financial statements.
SFAS 131 defines segments in terms of the Company's internal organization
structure. SFAS 132 revises employers' disclosures about pension and other
postretirement benefit

<PAGE>
plans. The Company will adopt these statements for fiscal year 1999. The 
adoption of these statements will have no impact on the Company's operating
results, statement of financial position or cash flows, as SFAS 130, 131 
and 132 provide standards on financial statement disclosure only.
 
  Statement of Financial Accounting Standards No. 133, "Accounting for
Derivative Instruments and Hedging Activities" (SFAS 133), was issued in June
1998. SFAS 133 provides standards on accounting and disclosure for derivative
instruments and requires that all derivatives be measured at fair value and
reported as either assets or liabilities in the statement of financial
position. The Company is required to adopt this statement no later than the
beginning of fiscal year 2000. The adoption of this statement will have no
impact on the Company's operating results, statement of financial position or
cash flows, as the Company does not invest in derivative instruments.
 
YEAR 2000 READINESS DISCLOSURE
 
  The Company is dependent upon its software programs and operating systems for
internal operations and for processing product orders with its customers and
suppliers. The Company has completed its assessment of the potential impact of
the Year 2000 on the Company's programs and systems. The Company manages its
information systems on a decentralized basis with stand-alone systems located
at each of its operating subsidiaries. The Company expects to complete the
remediation and testing of its information systems by September 30, 1999. Such
remediation efforts primarily relate to the repair of, as opposed to the
replacement of, affected systems. The Company expects to incur costs no greater
than $0.3 million, of which approximately $0.1 million has been incurred
through October 31, 1998, in order to make the Company's software programs and
operating systems Year 2000 compliant.
 
  The Company currently is unable to ascertain the magnitude of any Year 2000
problems that may exist in the software programs and operating systems of its
customers and suppliers, or the impact that any such problems could have on the
sales made and services provided by the Company to such customers or suppliers.
However, the Company's customer base is limited to a relatively small number of
customers with a relatively small number of purchase and sales transactions.
Also, the Company is not highly dependent upon electronic data interchange with
its vendors or suppliers. In the case of Year 2000 related failures, the
Company believes it can sustain manufacturing operations through manual
processes. The occurrence of Year 2000 related failures in the software
programs and operating systems of any of the Company's significant customers,
primarily the DoD and other U.S. government agencies, or suppliers could have a
material adverse effect on the Company's business, results of operations or
financial condition in subsequent periods, especially if it results in delays
in payments due the Company. The Company is diligently quantifying issues and
developing contingency sources to mitigate the risks associated with
interruptions in its business due to Year 2000 problems. Such contingencies
include obtaining necessary financing in the event the U.S. government is
unable to meet its scheduled payments.
 
FORWARD-LOOKING STATEMENTS
 
  In addition to historical information, this Annual Report includes certain
forward-looking statements within the meaning of Section 27A of the Securities
Act of 1933, as amended, and Section 21E of the Securities Exchange Act of
1934, as amended, which are intended to be covered by the safe harbors created
thereby. The forward-looking statements involve certain risks and
uncertainties, including, but not limited to acquisitions, additional financing
requirements, the decision of any of the Company's key customers (including the
U.S. government) to reduce or terminate orders with the Company, cutbacks in
defense spending by the U.S. government, increased competition in the Company's
markets and the impact of any Year 2000 problems, which could cause the
Company's actual results to differ materially from those projected in, or
inferred by, the forward-looking statements.

Fluctuations in 1998 revenues by product classification are due, in part,
to the acquisitions of Keco and Marlo Coil. Other fluctuations between
periods result primarily from changes in DoD requirements. As a result,
year-to-year comparisons of revenue by product may not be meaningful.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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, Engineered Air Systems, Inc.
(Engineered Air), Keco Industries, Inc. (Keco), Engineered Coil Company, d/b/a
Marlo Coil (Marlo Coil), and Engineered Specialty Plastics, Inc. (ESP). All
material intercompany accounts and transactions have been eliminated in
consolidation.

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

Revenue Recognition: Revenues on long-term contracts performed by Engineered
Air and Keco, 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 costs incurred bear to total estimated production costs.
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. Provisions for
estimated losses on contracts are recorded when identified. Marlo Coil and ESP
recognize revenue when products are shipped. Allowances for anticipated
doubtful accounts are provided based on historical experience and evaluation of
specific accounts. The allowance for doubtful accounts was $273,000 and
$283,000 at October 31, 1998 and 1997, 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 and
long-term debt, approximates book value at October 31, 1998 and 1997, based 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, 1998 and 1997, 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 52% and 42%,
respectively, of accounts receivable at October 31, 1998 and 1997 are due from
the U.S. government and its agencies, and due to the adequacy of the Company's
allowance for doubtful accounts.

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 of Engineered Air and Keco. Inventories of
Marlo Coil and ESP are valued at the lower of cost or market using the
first-in, first-out method.

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.

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.

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.

Cost in Excess of Net Assets Acquired: The excess of cost over net assets
acquired in purchase transactions is being amortized on a straight-line basis
over approximately 25 years.

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

Earnings Per Share: Basic earnings per share for 1998, 1997 and 1996 is based
on average basic common shares outstanding, after the effect of the stock split
described in Note K, of 4,785,335, 4,753,265 and 4,592,858, respectively.
Diluted earnings per share for 1998, 1997 and 1996 is based on average diluted
common shares outstanding, after the effect of the stock split described in
Note K, of 4,991,453, 4,954,787 and 4,879,944, respectively. Average diluted
common shares outstanding include common stock equivalents, which represent
common stock options as computed based on the treasury stock method.

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

<PAGE>
Impairment of Long-Lived Assets: Long-lived assets, including goodwill, are
reviewed for impairment 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.

Industry Information: Engineered Air and Keco operate predominately in one
segment--military ground support equipment--and substantially all revenues for
these subsidiaries are related to contracts with the U.S. government. Marlo
Coil manufactures and sells heat transfer and air movement equipment primarily
to defense contractors, mechanical contractors and industrial users. ESP
manufactures and sells made-to-order injection molded plastic products, and
manufactures and distributes a proprietary line of kitchen and bathroom
faucets.

Recently Issued Accounting Pronouncements: The Financial Accounting Standards
Board issued Statement of Financial Accounting Standards No. 130, "Reporting
Comprehensive Income" (SFAS 130), and Statement of Financial Accounting
Standards No. 131, "Disclosures about Segments of an Enterprise and Related
Information" (SFAS 131), in June 1997, and Statement of Financial Accounting
Standards No. 132, "Employers' Disclosures about Pension and Other
Postretirement Benefits" (SFAS 132), in February 1998. SFAS 130 establishes
standards for the reporting and display of the

                                                                          9 / /
<PAGE>
<PAGE>
Company's components of comprehensive income in the financial statements. SFAS
131 defines segments in terms of the Company's internal organization structure.
SFAS 132 revises employers' disclosures about pension and other postretirement
benefit plans. The Company will adopt these statements for fiscal year 1999.
The adoption of these statements will have no impact on the Company's operating
results, statement of financial position or cash flows, as SFAS 130, 131 and
132 provide standards on financial statement disclosure only. Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities" (SFAS 133) was issued in June 1998. SFAS 133 provides
standards on accounting and disclosure for derivative instruments, and requires
that all derivatives be measured at fair value and reported as either assets or
liabilities in the statement of financial position. The Company is required to
adopt this statement no later than the beginning of fiscal year 2000. The
adoption of this statement will have no impact on the Company's operating
results, statement of financial position or cash flows, as the Company does not
invest in derivative instruments.

NOTE B -- ACQUISITIONS

Effective February 1, 1998, Engineered Coil Company, a wholly-owned subsidiary
of the Company, acquired substantially all of the net assets of Nuclear
Cooling, Inc., d/b/a Marlo Coil, a manufacturer of heat transfer and air
movement equipment, from an investor group for approximately $25.4 million. The
fair value of the assets acquired, including goodwill of $17.1 million, was
$31.0 million and liabilities assumed totaled $5.6 million. The purchase price
was financed with approximately $2.9 million of available cash resources and
bank term debt of $22.5 million. The operating results of Engineered Coil
Company (Marlo Coil) are included in the Company's consolidated results of
operations from the date of acquisition.

On May 29, 1998, Marlo Coil purchased the exclusive rights to manufacture and
distribute the U.S. Navy/Marine products of Edge Electronics Corporation, d/b/a
McIntyre Engineering, for approximately $1.5 million. The fair value of the
assets acquired was $1.5 million, including goodwill of $1.4 million and a
seven-year covenant not to compete of $0.1 million. The purchase price was
financed with available cash resources.

On June 24, 1998, the Company purchased all of the outstanding common stock of
Keco Industries, Inc. (Keco), a manufacturer of military ground support
equipment, from an investor group for approximately $26.7 million. ($1.2
million of this amount relates to consideration to be paid to Keco's previous
shareholders in order for the Company to elect treatment of the transaction as
an asset purchase pursuant to Section 338(h)(10) of the Internal Revenue Code.
This election allows the Company to generate deductions for goodwill
amortization and additional depreciation for federal income tax purposes.
Section 338(h)(10) consideration to be paid is reflected on the October 31,
1998 Consolidated Balance Sheet as Due to Related Party.) The fair value of the
assets acquired, including goodwill of $7.4 million, was $29.6 million and
liabilities assumed totaled $2.9 million. The purchase price was financed with
approximately $4.2 million of available cash resources and bank term debt of
$22.5 million. The operating results of Keco are included in the Company's
consolidated results of operations from the date of acquisition.

The following unaudited pro forma summary presents the combined historical
results of operations for the years ended October 31, 1998 and 1997 as adjusted
to reflect the purchase transactions assuming the acquisitions had occurred at
November 1, 1996. These pro forma results are not necessarily indicative of the
combined results that would have occurred had the acquisitions actually taken
place on November 1, 1996, nor are they necessarily indicative of the combined
results that may occur in the future.

NOTE E -- NOTES PAYABLE AND LONG-TERM DEBT

In March 1998, the Company amended its bank credit agreement to provide a $45.0
million term loan and a $10.0 million revolving credit facility. Monthly
principal payments on the term loan began in September 1998 with final payment
due in May 2003. Borrowings under the term loan and the

/ / 10
<PAGE>
<PAGE>
revolving credit facility are subject to interest, at the Company's option, at
either the London Interbank Offered Rate (LIBOR) plus an applicable margin or
at the prime rate less 0.5%. The margin applicable to LIBOR varies from 0.5% to
1.5% depending upon the Company's ratio of total indebtedness to earnings
before interest, taxes, depreciation and amortization (leverage ratio). At
October 31, 1998, the effective interest rate under the credit agreement was
6.47%, and the Company had $10.0 million of availability under the revolving
credit facility, which carries an unused commitment fee of 0.125%. The credit
agreement contains certain covenants, including maintaining tangible net worth
of at least $23.7 million plus 50% of quarterly net income after April 30,
1998, and maintaining a leverage ratio no greater than 3.5 to 1 through October
31, 1999, no greater than 3.0 to 1 from October 31, 1999 to October 31, 2000
and no greater than 2.5 to 1 subsequent to October 31, 2000. Pursuant to the
terms of the credit agreement, the Company is subject to various other
financial and operating covenants and maintenance criteria, including
restrictions on the Company's ability to incur additional indebtedness, make
capital expenditures, create liens, dispose of material assets and enter into
merger transactions and lease agreements, and requirements to maintain certain
levels of consolidated cash flows, fixed charge coverage and consolidated
current ratios. At October 31, 1998, the Company was in compliance with all
restrictive covenants of its amended credit agreement. No compensating balance
is required or maintained related to the agreement.

Industrial revenue bonds in the amount of $750,000 were issued in September
1982 for construction of Keco's office building and primary manufacturing
facility. The bonds require the Company to make quarterly payments of principal
and interest through 2002 at a variable interest rate (5.695% at October 31,
1998). The bonds provide the Company with the option to purchase the facility
for a nominal amount when fully paid.

Long-term debt consists of:

The Company has guaranteed a bank term loan for the Engineered Support Systems,
Inc. Employee Stock Ownership Plan (ESOP). As loan payments are made, shares,
which had been purchased with proceeds from the loan, are released and
allocated to participant accounts. The bank holds the unallocated shares as
collateral for the loan. The loan, which matures in August 2003, bears interest
at the bank's prime rate and is payable in monthly installments of $12,300 plus
interest. Under the terms of the loan agreement, the Company is required to
make contributions to the ESOP in an amount no less than the amount sufficient
to fund the monthly installments.

Borrowings under the revolving credit facility, the bank term loan and the ESOP
loan are secured by substantially all assets of the Company and its
subsidiaries and are guaranteed by the Company. Annual principal payments of
long-term debt are $7,204,172 in 1999, $8,204,160 in 2000, $9,037,500 in 2001,
$10,204,168 in 2002 and $9,333,332 in 2003. Interest paid was $1,828,000,
$158,000 and $531,000 in 1998, 1997 and 1996, respectively.

Income taxes paid were $3,081,000, $3,228,000 and $2,239,000 in 1998, 1997 and
1996, respectively.

As of October 31, 1998, the Company had net operating loss carryforwards of
approximately $13,000 available to offset future taxable income, and investment
and targeted jobs tax credit carryforwards of approximately $190,000 available
to offset future federal income taxes which would otherwise be payable. These
carryforwards, which relate to ESP, expire in 2003. The Company expects the
carryforwards to be fully utilized and, accordingly, has recorded a deferred
tax asset relating to the carryforwards.

NOTE G -- SHAREHOLDERS' EQUITY

The Company has established plans whereby options may be granted to employees
and directors of the Company to purchase shares of the Company's common stock.
Options granted are at an option price equal to the market value on the date
the option is granted. Subject to continuation of employment, all options must
be exercised within five years from the date of grant and are exercisable at
any time during this period. As of October 31, 1998, 869,038 shares of unissued
common stock were authorized and reserved for outstanding options, which had a
weighted average remaining contractual life of 3.7 years at that date.

The Company applies Accounting Principles Board Opinion No. 25, "Accounting for
Stock Issued to Employees", and related interpretations in accounting for the
stock option plans. Accordingly, no compensation expense has been recognized
for stock option awards. Had compensation expense for the Company's stock
option awards been determined based upon their grant date fair value consistent
with the methodology prescribed under Statement of Financial Accounting
Standards No. 123, "Accounting for Stock-Based Compensation" (SFAS 123), the
Company's net income would have been reduced by $825,000, or $.17 per average
diluted common share outstanding, in 1998 and $219,000, or $.04 per average
diluted common share outstanding, in 1997. The fair value of options at the
grant date was estimated using the Black-Scholes model with the following
weighted average assumptions for 1998 and 1997, respectively: an expected life
of 3.2 years and 3.6 years, volatility of 50% and 42%, a dividend yield of
0.30% and 0.17%, and a risk-free interest rate of 4.67% and 6.06%. The weighted
average fair value of options granted in 1998 and 1997 was $5.13 and $2.53,
respectively. Transactions involving the stock option plans are as follows:

NOTE H -- RETIREMENT PLANS

Engineered Air has a non-contributory defined benefit plan covering
substantially all full-time employees covered by a collective bargaining
agreement. The Company's funding policy is to make annual contributions to the
plan sufficient to fund the normal cost, including amortization of prior
service cost, over a period of 15 years. A summary of the components of net
periodic pension cost for the defined benefit plan is as follows:

Assumptions used in accounting for the defined benefit plan in 1998, 1997 and
1996 were a weighted average discount rate of 6.75 percent, 7.5 percent and
7.75 percent, respectively, and an expected long-term rate of return on assets
of 9.0 percent. The decrease in the discount rate assumption resulted in an
increase of $421,000 in the accumulated and projected benefit obligation as of
October 31, 1998. The following table sets forth funded status and amounts
recognized in the consolidated balance sheets for the defined benefit pension
plan:

The Company has an Employee Stock Ownership Plan (ESOP) covering all salaried
employees of Engineered Air, and all employees of ESP, Marlo Coil (effective
July 1, 1998) and Keco (effective January 1, 1999). 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 in an amount no less than the
amount sufficient to pay the monthly installments of the ESOP bank loan. All
employee and employer contributions to the ESOP are 100 percent vested. The
Company has recorded expenses based on contributions to the ESOP for the years-
ended October 31, 1998, 1997 and 1996 of $481,000, $377,000 and $293,000,
respectively. Interest payments on the ESOP bank loan were $62,000, $81,000 and
$93,000 in 1998, 1997 and 1996, respectively. The Company accounts for ESOP
shares under the cash payment method. All ESOP shares are considered
outstanding for purposes of computing net income per share.

<PAGE>
Prior to July 1, 1998, the Marlo Coil Employee Retirement Plan (Marlo Plan)
covered all full-time employees of Marlo Coil. The Marlo Plan provided for a
matching contribution by the Company of 50% of each employee's contributions up
to a maximum of 4% of the employee's earnings. The Company also made
discretionary contributions to the Marlo Plan. The Company has recorded
expenses based on contributions to the Marlo Plan for the year ended October
31, 1998 of $86,000. The Marlo Plan was terminated effective June 30, 1998 and
all assets were transferred to the ESOP.

Prior to January 1, 1999, all full-time employees of Keco were covered by the
Keco Industries 401(k) Profit Sharing Plan (Keco Plan). The Keco Plan provided
for a matching contribution by the Company of 100% of each employee's

NOTE I -- SEGMENT INFORMATION

The Company operates in two industry segments: the military support and related
industrial/commercial equipment segment and the custom molded plastic products
segment. The military support and related industrial/commercial equipment
operations involve the engineering, fabrication and assembly of a broad range
of military support equipment designed for rapid deployment around the world,
as well as related heat transfer and air handling equipment sold to commercial
and industrial users. The custom molded plastic products operations involve the
manufacture and sale of a broad range of injection molded resin products, as
well as the manufacture and sale of a proprietary line of plastic faucets. All
corporate expenses and assets have been allocated to the business segments.
Approximately 55%, 82% and 79%, respectively, of 1998, 1997 and 1996
consolidated revenues were from two customers--45%, 71% and 73%, respectively,
from the U.S. government and 10%, 11% and 6%, respectively, from another
customer. The Company's export net sales and intersegment net sales are not
significant. Information by industry segment is summarized as follows:

NOTE J -- 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.

NOTE K -- STOCK SPLIT

On June 26, 1998, the Company effected a 3-for-2 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 plans, in this report have been restated to
reflect this stock split.

/ /REPORT OF INDEPENDENT ACCOUNTANTS

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

  In our opinion, the accompanying consolidated balance sheets and related
consolidated statements of income, of shareholders' equity and of cash flows
present fairly, in all material respects, the financial position of Engineered
Support Systems, Inc. and its subsidiaries at October 31, 1998 and 1997, and
the results of their operations and their cash flows for each of the three
years in the period ended October 31, 1998, in conformity with generally
accepted accounting principles. These financial statements are the
responsibility of the Company's management; our responsibility is to express an
opinion on these statements based on our audits. We conducted our audits of
these statements in accordance with generally accepted auditing standards,
which require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An
audit 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 the opinion expressed above.
