FORWARD LOOKING INFORMATION

    This Annual Report contains "forward looking statements" within the meaning
of the Private Securities Litigation Reform Act of 1995. Such forward looking
statements are based on management's expectations, estimates, projections and
assumptions. Words such as "expects," "anticipates," "intends," "plans,"
"believes," "estimates," and variations of such words and similar expressions
are intended to identify such forward looking statements which include, but are
not limited to, projections of revenues, earnings, segment performance, cash
flows and contract awards. These forward looking statements are subject to risks
and uncertainties which could cause the Company's actual results or performance
to differ materially from those expressed or implied in such statements. These
risks and uncertainties include, but are not limited to, the following: the
Company's successful execution of internal performance plans; performance issues
with key suppliers, subcontractors and business partners; legal proceedings;
product demand and market acceptance risks; the effect of economic conditions;
the impact of competitive products and pricing; product development,
commercialization and technological difficulties; capacity and supply
constraints or difficulties; legislative or regulatory actions impacting the
Company's energy segment and transportation business; changing priorities or
reductions in the U.S. government defense budget; contract continuation and
future contract awards; and U.S. and international military budget constraints
and determinations.

ITEM 1. BUSINESS

    At December 31, 1999, the operations of United consist of three principal
business segments: defense, transportation and energy systems, principally
conducted through three wholly-owned subsidiaries.

DEFENSE

AAI CORPORATION

    AAI Corporation ("AAI") is engaged in engineering, development and
manufacture in the following major areas: (1) training and simulation systems;
(2) automatic test equipment for electronic systems and components;
(3) unmanned aerial vehicle systems; (4) ordnance systems; and (5) mechanical
support systems for industrial, military, and marine applications. Since its
inception, AAI's business has been primarily in support of the U.S. Department
of Defense ("DOD"). Since 1990, the Company has emphasized diversification into
other markets to reduce its dependence on the DOD. The United States defense
budget has been significantly reduced in recent years and this trend is expected
to continue. In 1999 approximately 79% of the sales volume of AAI consisted of
research, development and production of military items under domestic defense
contracts compared to 70% in 1998. Certain of the contracts currently being
worked on by AAI involve testing systems for U.S. Navy aircraft, training
equipment for the U.S. Air Force and U.S. Navy, and weapons handling systems for
the U.S. Army. International defense contracts accounted for 5.6% of sales in
1999 as compared to 14% in 1998. These contracts generally related to unmanned
aerial vehicle systems and weapon training systems for foreign governments. The
balance of AAI's non-transportation business consists of work performed in the
non-defense markets, principally hydraulic test equipment.

    Because of the variety of its activities, it is not possible to state
precisely the competitive position of AAI with respect to each of its product
lines. In the area of training and simulation systems, AAI is one of
approximately ten leading organizations developing equipment for the U.S.
Government. AAI's ability to obtain orders for training and simulation systems
is dependent principally on the ability, expertise and training of its employees
and the level of funding by the DOD and foreign military users. A number of
large and small companies produce automatic test equipment that compete with AAI
for

                                       2

market share. In the area of weapons and munitions, AAI ranks among
approximately ten leading companies engaged in development work. However, AAI's
production activity in this field is less significant. AAI began development in
the Unmanned Aerial Vehicle ("UAV") business in 1986. The Company produces the
highly successful Pioneer Unmanned Aerial Vehicle employed by the United States
during Operation Desert Storm and in the conflicts in Somalia and Bosnia. In
addition, AAI has other UAV systems and products which it markets
internationally. AAI is one of several large and small competitors in this
field.

    AAI's administrative offices and its principal manufacturing and engineering
facilities are located in Hunt Valley, Maryland.

SYMTRON SYSTEMS, INC.

    Symtron Systems, Inc. ("Symtron") is a world leader in the development and
sale of advanced, computer controlled, gas-fueled, live-fire firefighter
training systems for public and private industry. Symtron started development of
these systems under an initial contract with the U.S. Army in 1978. Contingent
purchase price amounts were payable if certain pretax profits, as defined in the
purchase agreement, were earned for each of the years in the five year period
ended December 31, 1998. Included in general and administrative expenses in 1998
and 1997 are such contingent payments totaling $265,000 and $723,000,
respectively. The 1999 general and administrative expense includes $107,000 as
an adjustment of 1998 contingent payments. Symtron's 1999 sales consisted of
production for military and commercial customers. The main office and plant of
Symtron are located in Fair Lawn, New Jersey. In the international markets,
Symtron is faced with significant competition from several small firms.

ENERGY SYSTEMS

DETROIT STOKER COMPANY

    Detroit Stoker Company ("Detroit Stoker") is a leading supplier of stokers
and related combustion equipment for the production of steam used in heating,
industrial processing and electric power generation around the world. Detroit
Stoker offers a full line of stokers for burning bituminous and lignite coals as
well as biomass, municipal solid waste and industrial by-products. Detroit
Stoker also provides auxiliary equipment and services including fuel feed and
ash removal systems, gas/oil burners and complete aftermarket services for its
products. Principal markets include Pulp and Paper, Public Utilities,
Independent Power Producers, Industrial manufacturing, Institutional and
Cogeneration facilities. The products of Detroit Stoker compete with those of
several other manufacturers. Competition is based on several factors including
price, features and performance.

    Detroit Stoker's waste to energy technology is used extensively in both
public and private plants that generate steam and power from municipal waste.
Its solid fuel combustion technologies are particularly well suited for biomass
fuels that generate power from waste products such as bark, sugar cane, sawdust,
sunflower hulls, and poultry litter. The combustion of biomass fuels is gaining
worldwide popularity, as it does not contribute to global warming.

    Detroit Stoker exports its products to Europe, Asia, South America and
Australia, and is a market leader in North America. Detroit Stoker's
globalization strategy is to further expand both its customer and supplier base
in each of these regions.

    Detroit Stoker's administrative offices and its principal manufacturing
operations are located in Monroe, Michigan. Detroit Stoker also operates a
foundry through a subsidiary (Midwest Metallurgical Laboratory, Inc.) in
Marshall, Michigan. The foundry is engaged in the manufacture of grey and
ductile iron, stainless steel and special alloy iron castings that are
principally used in Detroit Stoker's products.

                                       3

TRANSPORTATION

    AAI Transportation Systems, a division of AAI, is engaged in the
manufacturing and integration of transit systems primarily for municipal
customers within the United States. Its products and services are focused in
overhaul, fabrication, assembly and systems integration.

    Electric Transit, Inc. (ETI), a corporation owned 35% by AAI and 65% by
Skoda, a Czech Republic firm, has become one of the domestic market leaders in
manufacturing electric trolley buses. It has won contracts in both Dayton, Ohio
for the Miami Valley Regional Transit Authority and the city and county of San
Francisco, the only such contracts awarded in the United States since 1994. ETI
is an unconsolidated affiliate of AAI and accordingly, AAI records its equity
share of income or loss in ETI. Under these contracts which are valued at
$32 million and $174 million, respectively, AAI has received subcontracts of
$9.4 million and $54.4 million, respectively.

    In addition to its electric trolley bus business, AAI performs overhaul and
remanufacturing work for a variety of transit customers and produces an
assortment of transit equipment including fabricated trucks for both heavy and
light railcars.

    The products and services of Transportation Systems compete with those of
several other larger as well as smaller manufacturers. The main office and
operating facilities are located in Hunt Valley, Maryland.

    For additional information concerning United's subsidiaries reference is
made to information set forth in the Letter to Shareholders contained in
United's 1999 Annual Report to Shareholders (the "Annual Report"), which letter
is incorporated herein by reference. Reference is also made to the information
set forth in the section entitled "Management's Discussion and Analysis of
Financial Condition and Results of Operations" in the Annual Report, which
section is incorporated herein by reference.

GENERAL

EMPLOYEES

    As of March 1, 2000 United and its subsidiaries had approximately 1,600
employees. Approximately 113 of these employees are represented by several
unions under contracts expiring between July 2000 and January 2001. United
considers its employee relationships to be satisfactory.

PATENTS

    United and its subsidiaries own more than 100 United States patents relating
to various products, including stokers, marine equipment, ordnance and
electronic equipment and firefighter trainers. In addition, United has numerous
pending applications for patents. There is no assurance as to how many patents
will be issued pursuant to these pending applications. The applications relate
to a wide variety of fields, including automation control systems, ordnance
devices, and electronic developments. No patent is considered to be of material
importance to United.

RESEARCH AND DEVELOPMENT

    During 1999, 1998 and 1997, the subsidiaries of United (exclusive of AAI)
expended approximately $117,000, $201,000 and $144,000, respectively, on the
development of new products and the improvement of existing products. All of the
programs and the funds to support such programs are sponsored by the subsidiary
involved. In addition to the above amount, AAI is engaged in research and
development primarily for the U.S. Government.

BACKLOG

    The backlog of orders by industry segment at December 31, 1999 and 1998 was
as follows:



                                                       1999           1998
                                                   ------------   ------------
                                                            
Defense..........................................  $153,048,000   $146,634,000
Energy Systems...................................     4,750,000      9,334,000
Transportation...................................   135,018,000     53,860,000


    Except for approximately $93,000,000, substantially all of the backlog
orders at December 31, 1999 are expected to be filled in 2000.

GOVERNMENT CONTRACTS

    No single customer other than the U.S. Government, principally the
Department of Defense, accounted for 10% or more of net sales during the year.
Sales to the U.S. Government normally carry a lesser margin of profit than
commercial sales and may be subject to price redetermination under certain
circumstances. Contracts for such sales can be terminated for the convenience of
the U.S. Government.

ITEM 3. LEGAL PROCEEDINGS

    The Company, along with numerous other parties, has been named in five tort
actions in Maricopa County Superior Court relating to environmental matters
based on allegations partially related to a predecessor's operation of a small
facility at a site in the State of Arizona that manufactured semi-conductors
between 1959 and 1960. All such operations of the Company were sold by 1961.
These tort actions seek recovery for personal injury and property damage among
other damages based on exposure to solvents allegedly released at the site.

    These suits allege that the plaintiffs have been exposed to contaminated
groundwater in the Phoenix/Scottsdale, Arizona area and suffer increased risk of
disease and other physical effects. They also assert property damages under
various theories; seek to have certain scientific studies performed concerning
health risks, preventative measures and long-term effects; and seek incidental
and consequential damages, punitive damages, and an injunction against actions
causing further exposures.

    The Company reached an agreement to settle all of these matters with the
plaintiffs for, among other items, a cash payment of $4,250,000. The Superior
Court of Maricopa County has scheduled a hearing for final approval of the
settlement for March 14, 2000.

    Detroit Stoker was notified in March 1992 by the Michigan Department of
Natural Resources ("MDNR") that it is a potentially responsible party in
connection with the clean-up of a former industrial landfill located in Port of
Monroe, Michigan. MDNR is treating the Port of Monroe landfill site as a
contaminated facility within the meaning of the Michigan Environmental Response
Act ("MERA"). Under MERA, if a release or a potential release of a discarded
hazardous substance is or may be injurious to the environment or to the public
health, safety, or welfare, MDNR is empowered to undertake or compel
investigation and response activities in order to alleviate any contamination
threat. Detroit Stoker intends to aggressively defend these claims. At this
time, no estimate can be made as to the amount or range of potential loss, if
any, to Detroit Stoker with respect to this action.

    The Company is involved in various other lawsuits and claims, including
