                                     PART I

Item 1. Business

    Dynamics Research Corporation (referred to as DRC or the company) was
incorporated in 1955 under the laws of the Commonwealth of Massachusetts. The
company is an innovative solutions provider, partnering with customers to apply
proven processes and technologies. The company delivers engineering, logistics
and information technology services and precision manufactured products that
enhance the performance and cost effectiveness of its customers' mission
critical systems. The company's Systems and Services segment represented 86% of
revenue from continuing operations for the year ended December 31, 1999.
Precision manufactured products, which includes the Encoder and Metrigraphics
business segments, represented 14% of 1999 revenue from continuing operations.

Systems and Services Segment

    The company provides systems analysis, integration and software design and
development services. The Segment's information technology offerings also
include installation, systems operation, and maintenance. Systems built by the
company are used for aircraft maintenance and parts tracking, supply chain
management, training requirements, and for managing state government health and
human services commitments.

    The company's major Department of Defense (referred to as DoD) information
systems programs are often referred to as logistics information systems. These
systems manage data related to inventory requirements and control, maintenance
and repair, warranty analysis, supply, and distribution of numerous products and
parts.

    For more than thirty years, the company has provided services to the U.S.
Navy Strategic Systems Program office in three areas. First, the company
develops and maintains performance, reliability, and logistics databases for the
inertial guidance instruments housed in missile guidance systems and submarine
inertial guidance systems. These databases track detailed information on
thousands of component parts comprising the systems. In connection with these
databases, the company has successfully integrated customer workflow and
database activity information with Internet technology. Second, the company
provides independent analysis and monitoring of submarine-based, inertial
guidance systems and electronic modules. The company designs, constructs,
installs and supports test equipment used in the U.S. Navy Trident program.
Third, the company is involved in the design of a closed-loop system used in the
field of parameter control in semiconductor manufacture. This process is being
developed together with other companies under the auspices of the U.S. Navy in
the San Diego, California, Space and Naval Warfare Systems Center. The company
performs computer-aided, semiconductor circuit analysis for its Navy customer as
well as commercial companies.

    The DRC-developed Weapon Systems Management Information System (WSMIS)
assesses the "health" and capability of the U.S. Air Force weapon systems to
meet wartime objectives. The company has served as the overall functional
integrator of WSMIS and the developer of most




<PAGE>

WSMIS modules. The company currently provides WSMIS operational and software
development support. As a decision-support tool for assessing the impacts of
logistics status on potential wartime capabilities, WSMIS computes inventory
requirements, purchasing needs, and logistics capability assessments for
complex, high-priced aircraft spare parts necessary to meet aircraft
availability requirements.

    A major component of the company's DoD business consists of a wide variety
of engineering, technical assistance and management support services performed
under various indefinite order, indefinite quantity contracts. Work performed
under these contracts is generally done on a time and materials basis utilizing
a wide range of the company's technical and management skills to plan, analyze,
design, test, support, train, maintain, and dispose of a variety of complex
systems. Systems include radar, missile, aircraft, information, logistics and
munitions.

    The company provides support at all stages of a system's life cycle. In
response to emerging requirements, the company helps its Federal Government
customers define, develop, and initiate new programs. The company also helps
customers obtain program approval, conduct strategic planning, and evaluate
proposals from private contractors. After prime contract awards, the company
helps monitor contractor activities, evaluate progress, and measure performance
against program requirements. Products and services include computer-based
training, systems integration, and business process improvement/reengineering.
Under a variety of contracts, the company supports the U.S. Air Force at bases
such as Hanscom Air Force Base, Scott Air Force Base, Langley Air Force Base,
Maxwell Air Force Base, Gunter Annex, Peterson Air Force Base, and Eglin Air
Force Base.

    The company provides engineering services in excess of $35 million per year
to the Electronics Systems Center (ESC). Under the Information Technology
Support Program (ITSP), the company provides acquisition management, systems
engineering, systems integration, test and evaluation, and computer based
training to ESC's System Program Offices and Product Acquisition Directorates.

    In 1995, the U.S. Air Force awarded the company a five-year contract for
Technology Task-Order Engineering Services (TTOES). Originally valued at up to
$23.7 million, in 1997 the contract ceiling was increased to $31.2 million. The
company has provided engineering, logistics, and software support on programs
such as the B-1B, the B-2, the B-52, the KC-135, and the E-3A aircraft repair,
maintenance, and upgrade programs. From its origin at the Oklahoma City Air
Logistics Center (ALC), DRC has expanded its TTOES task orders to include work
at other ALC's located at Warner Robins, GA; Ogden, UT; and San Antonio, TX.
Additional tasking has centered on providing support to Air Force reengineering
and business process improvement initiatives at these ALC's. Recently, the
company was awarded a prime contract for the Design Engineering Support Program
at Ogden ALC.

    The company has designed, developed, installed and, since August 1999, has
operated a logistics and supply chain information management system to support
the U.S. Air Force's landing gear maintenance, repair and overhaul (MRO)
operations at Hill Air Force Base in Ogden,




<PAGE>

Utah. Recently, the company was awarded additional MRO workload for Gas Turbine
Engines, Hydraulics and Armament Systems at Ogden.

    Since 1993, the company has provided the US Army Aviation and Missile
Command with specialized studies and analyses in aviation/missile system
development, acquisition and sustainment. Since 1996, the company has been a
prime contractor on a five-year, $33 million contract under a U.S. Army program
known as Programmatic and Technical Support. The company supports a broad range
of helicopter and missile systems in varying life cycle stages. Additionally,
the company supports other U.S. Army activities with acquisition logistics,
systems engineering and other related program management services at the
Tank-Automotive Command and Communications-Electronics Command from its office
in Huntsville, Alabama.

    Combining its expertise in weapon system acquisition processes with its
expertise in systems analysis, design, training and simulation and human
factors, the company performs human-systems integration and force analysis.
Since 1987, the company has provided force analysis support to the Army Research
Laboratory. These activities are focused on developing tools that support
analyzing soldier and system effectiveness, identifying and assessing force
improvement options (doctrine, training, leader development, organization and
material), and ensuring soldier considerations are addressed in force
improvements. Also, under contract from the U.S. Army Research Laboratory, the
company provides analysis, system development and support in several functional
areas which include assessment of manpower, personnel and training issues;
analysis of soldier systems performance; and integration of methods and
databases for use by system designers.

    DRC is the developer of the Training System Requirements Analysis (TSRA)
Tools, which are a set of computer programs designed to help instructional
designers perform the initial phases of the Instructional Systems Development
(ISD) process. The TSRA Tools have been developed with the Naval Air Warfare
Center Training Systems Division and are widely used throughout the DoD by
government and contractor organizations. The market for DRC's TSRA Tools has
expanded beyond the military to include the Federal Aviation Administration and
National Mine Health and Safety Academy.

    As a subcontractor to Lockheed Martin, the company is supporting the U.S.
Army's Warfighter Simulation 2000, a simulation system supporting the training
of commanders and staff under a wide variety of battlefield scenarios. The
company's services include providing military subject matter experts, software
and human factors engineering, database development for equipment and knowledge
acquisition, as well as manpower staffing reduction analysis.

    The company is also a subcontractor to Lockheed Martin for the Close Combat
Tactical Trainer (CCTT) program. CCTT simulates Army tank and mechanized
infantry units from vehicle crews to the battalion level. CCTT uses distributed,
interactive simulation technology to provide a "virtual" training environment.
DRC conducts all manpower and personnel integration activities associated with
the CCTT. DRC is playing a similar role as a subcontractor to Lockheed Martin on
the United Kingdom Combined Arms Tactical Trainer, the UK's version of the CCTT.



<PAGE>

    The company is a subcontractor to Raytheon on the U.S. Air Force National
Air and Space Model. The company develops conceptual models and collects data on
mission space objects and processes.

    In 1996, the company began working on a U.S. Army, four-year contract to
implement, apply, and manage DRC-developed teamwork training designed to improve
teamwork and reduce errors in emergency medicine. The program, called MedTeams,
has been instituted in a dozen military and civilian hospitals in the United
States.

    In March 1998, DRC was awarded a contract under the Air Force Aeronautical
Systems Center Advisory and Assistance Services (A&AS) Omnibus program. The
purpose of this contract is to provide support for engineering, manufacturing,
configuration/data management, acquisition management and test and evaluation
required in the acquisition, development, production and sustainment of various
equipment and weapons systems. The contract provides DRC the opportunity to
compete against other companies for tasks under the A&AS Omnibus program over
three years.

    In recent years, the company has expanded beyond the DoD marketplace and won
various state and Federal agency contracts. The company provides systems design,
development, implementation and support services to Health and Human Services
Departments in four states-Ohio, New Hampshire, Arkansas and Colorado. The
company implemented a distributed computer-based Statewide Automated Child
Welfare Information System (SACWIS) for the State of New Hampshire. This system
manages child welfare cases handled by the State's Department of Health and
Human Services. Under ongoing contracts DRC provides additional functional and
technical enhancements to the SACWIS system as well as other information
technology services. The company is also developing a SACWIS for the State of
Arkansas.

     In December 1997, the company received a three-year contract from the State
of Colorado Department of Human Services to serve as a prime contractor for its
Children, Youth and Families project. The contract was a result of a competitive
procurement for the design, development and implementation of a child welfare
and youth corrections system consisting of software, training and a state-wide
computer network infrastructure.

    In addition, the company installed, under a prime contract, the Ohio
state-wide computer network infrastructure for the Support Enforcement, Tracking
Systems and Ohio Works First Programs.

    The company continues to provide the U.S. Department of Treasury with
information technology services for the Internal Revenue Service and other
Treasury departments. During 1998 and 1999 the company's work for the IRS
focused on year 2000 procedures. In 2000, the company will be focusing on full
life cycle development of the Compliance Research Information Service.

Precision Manufactured Products

    The company's precision manufacturing business consists of two business
segments, Encoder and Metrigraphics.

    The Encoder Division designs, manufactures, and markets a line of optical
encoders that convert analog motion and position information into digital
signals used in a wide variety of industrial products and systems which include:
machine tools, robotics, engine fuel-control systems, packaging equipment and
factory automation equipment. Optical encoders are essential elements of today's
electronically-controlled systems and equipment.

    The Metrigraphics Division's expertise centers on photolithography, thin
film deposition of metals and dielectrics and electro forming. Metrigraphics'
superior ability to design and manufacture components and maintain critical
tolerances is an important driver for a wide range of high-technology
applications. The company currently applies these technologies in four distinct
applications: 1) computer printer nozzle plates and hard drive test devices; 2)
medical applications for micro flex circuits used in angioplasty and for
bloodtesting; 3) electrical test devices for application in flexible interposers
and 3-D microstructures; and 4) devices used in the manufacture of fiber optic
system components requiring precision alignment and 3-D micro structures.

    Metrigraphics' highest volume application is currently for nozzles used in
inkjet printer cartridges. In addition to its electroform parts for printers and
medical instruments, Metrigraphics manufactures precision glass parts for
computer peripherals, factory automation equipment, electronic instrumentation
and semiconductor equipment.

Telecommunications Fraud Control Systems

    In 1996, the company was licensed to enhance, market and maintain a
telecommunications fraud control system developed by Pacific Bell Telephone
Company. The company made significant investments in this and related systems
and software technologies to broaden the types of telephone fraud detected and
to position the product for sale to competitive local exchange carriers and
others. The company's customers included the regional Bell operating telephone
companies. In December 1998, the company adopted a plan to exit this business
during 1999. The business was sold in June 1999.

Software Development Technology

    In 1998, the company exited its Visual Magic business which developed
object-oriented software for Internet applications. The company sold an
exclusive license to the software and other assets in exchange for an equity
interest in the acquiring company, Empresa, Inc. In 1999, Empresa ceased
operations, and the company wrote off its investment of $1.4 million.


<PAGE>

Sales and Marketing

    Contracts with defense, state and other government agency customers are
obtained by marketing and technical personnel employed by the company. The
company's other products are sold by sales personnel employed by the company and
outside sales representatives.

Government Contracts

    During 1999, the company's revenues from contracts with the DoD, either as
prime contractor or subcontractor, accounted for approximately 66% of the
company's total revenues. The company's contracts with the Government are
generally subject to termination at the convenience of the Government. However,
the company would be reimbursed for its allowable costs to the time of
termination and would be paid a proportionate amount of the stipulated profit
attributable to the work actually performed. Although Government contracts may
extend for several years, they are generally funded on an annual basis and are
subject to reduction or cancellation in the event of changes in Government
requirements or budgetary concerns. If the U.S. Government curtails expenditures
for research, development and consulting activities, such curtailment might have
an adverse impact on the company's revenues and earnings.

    The company's revenues from contracts with four different states accounted
for 16% of 1999 revenues. Revenues under various contracts with the State of
Ohio accounted for approximately 7% of 1999 revenues. The company's state
contracts are generally either fixed-price or time and material. In certain
instances, funding for these contracts is subject to annual state legislative
approval.

    The company's government contracts fall into one of three categories: (1)
fixed-price, (2) time and materials, and (3) cost plus fixed-fee. Under a
fixed-price contract, the government pays an agreed upon price for the company's
services or products, and the company bears the risk that increased or
unexpected costs may reduce its profits or cause it to incur a loss. Conversely,
to the extent the company incurs actual costs below anticipated costs on these
contracts, the company could realize greater profits. Under a time and materials
contract, the government pays the company a fixed hourly rate intended to cover
salary costs and related indirect expenses plus a profit margin. Under a cost
plus fixed-fee contract, the government reimburses the company for its allowable
direct expenses and allowable and allocable indirect costs and pays a negotiated
fee.

Backlog

    At December 31, 1999, the company's backlog of unfilled orders was
approximately $106.7 million compared with $105.4 million at December 31, 1998.
The company expects that substantially all of its backlog at December 31, 1999
will be filled during the year ending December 31, 2000. The company has a
number of multi-year contracts with agencies of the U.S. and state governments
on which actual funding generally occurs on an annual basis. The company's
business does not have seasonal characteristics but a portion of its funded
backlog is based on annual purchase contracts, and the amount of funded backlog
as of any date can be affected by the timing of order receipts and deliveries
thereunder.



<PAGE>

Competition

    The company competes with both domestic and foreign firms, including larger
diversified companies and smaller specialized firms. The U.S. Government's own
in-house capabilities are also, in effect, competitors because various agencies
perform certain types of services which might otherwise be performed by the
company. The principal competitive factors for systems and services are price,
performance, technical competence and reliability. In the commercial businesses,
the company competes with other manufacturers of encoders, electroform vendors
and suppliers of precision measurement scales. The principal competitive factors
affecting the precision components manufacturing businesses are price, product
quality and custom engineering to meet customers' system requirements.

Research and Development

    The company expended approximately $1.5 million (inclusive of overhead and
other indirect costs) on new product and service development during the year
ended December 31, 1999, as compared to expenditures of $2.7 million during 1998
and $1.2 million during 1997.

Raw Materials

    Raw materials and components are purchased from a large number of
independent sources and are generally available in sufficient quantities to meet
current requirements.


Environmental Matters

    Compliance with federal, state and local provisions relating to the
protection of the environment has not had and is not expected to have a material
effect upon the capital expenditures, earnings or competitive position of the
company.

Employees

    At December 31, 1999, the company had 1,613 employees.

Proprietary Information

    Patents, trademarks and copyrights are not materially important to the
business of the company. The U.S. Government has certain proprietary rights in
processes and data developed by the company in its performance of government
contracts.

Item 2.  Properties

    The company leases offices and other facilities, totaling approximately
479,000 square feet, which are utilized for its federal and state government
services, manufacturing and warehousing



<PAGE>

operations as well as its marketing and engineering offices. The company has
manufacturing and office space in Wilmington, Massachusetts under three leases
totaling 113,000 square feet, expiring in 2000, with options to the year 2005.
The remaining leased facilities consist of offices in 26 locations across the
United States. The company owns a 135,000 square foot facility in Andover,
Massachusetts that is utilized for its DoD service operations and corporate
administrative offices.

    The company's total rental cost for 1999 was $3.7 million.

    The company believes its properties are adequate for its present needs.


Item 3.  Legal Proceedings

    The company is not a party to any material litigation.
