PART I

Item 1. Business

    Dynamics Research Corporation (referred to as DRC or the 
Company) was organized in 1955 under the laws of the 
Commonwealth of Massachusetts. The Company develops and 
operates computer and communication-intensive information 
systems, provides engineering, management support and 
information technology services, and produces precision 
manufactured components for industrial measurement and control.   
The Company's Systems and Services segment represents 85% of 
revenue from continuing operations for the year ended December 
31, 1998.  Precision manufactured products represent 15% of 
1998 revenue from continuing operations and include encoders 
and electroformed parts.  The Company was also engaged in the 
development and sale of telecommunications fraud control 
systems and object-oriented software development technology.

Systems and Services Segment

    DRC 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 DRC 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 DRC-developed product
management information systems manage data related to inventory
requirements and control, maintenance and repair, warranty
analysis, supply, and distribution of numerous products and parts. 

    For nearly 30 years, the Company has assisted the U.S. Navy 
Fleet Ballistic Missile program office in the design, 
development, and operation of inertial systems.  The Company 
has extensive experience with the Polaris, Poseidon, and 
Trident missile guidance systems and submarine inertial 
navigation systems. The Company develops and maintains 
performance, reliability, and logistics databases for the 
inertial guidance instruments housed in those 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.  This information is used by the customer for a 
wide range of operating management tasks and decision making. 

    The Company provides independent analysis and monitoring of 
submarine-based, inertial guidance systems and electronic 
modules for the U.S. Navy Fleet Ballistic Missile Program 
Office. DRC's Inertial Instrument Test Laboratory is equipped 
for full-scale performance testing of navigational quality 
inertial instruments.  The Company designs, constructs, 
installs, trains, and supports test equipment used in the U.S. 
Navy Trident program. 

    DRC is also involved in the design of a closed-loop system used 
in the field of parameter control in semiconductor manufacture. 
This process is being developed along with other companies 
under the auspices of the U.S. Navy in the San Diego, 
California, Space and Naval Warfare Systems Center.  DRC 
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.  DRC has 
served as the overall functional integrator of WSMIS and the 
developer of most 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, 
software, 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, DRC 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, 
and Peterson Air Force Base. 

    In 1995, the U.S. Air Force awarded DRC 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.  DRC 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.    

    Since 1993, DRC 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.  DRC 
supports a broad range of helicopter and missile systems in 
varying life cycle stages.  Additionally, DRC supports other 
U.S. Army activities with acquisition logistics, systems 
engineering and other related program management services 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, DRC performs human-systems 
integration and force analysis. Since 1987, DRC 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, DRC 
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 (NAWCTSD) 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, DRC 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.  DRC 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.

    DRC 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.

    DRC is a subcontractor to Raytheon on the U.S. Air Force 
National Air and Space Model (NASM).  The Company is developing 
conceptual models and collecting data on mission space objects 
and processes.

    The Company is in its third year of a U.S. Army, four-year 
contract, valued at approximately $13.0 million, to implement, 
apply, and manage DRC-developed teamwork training principles to 
improve performance in high-pressure environments.  The project 
focus is on improving teamwork in emergency-room settings at 
more than 15 civilian and military hospitals.

    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 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.

    In February 1997, DRC was awarded a contract to design, 
deliver, install and maintain a statewide information 
technology (IT) infrastructure that supports the Ohio Child 
Support Enforcement Tracking System (SETS).   The IT 
infrastructure the Company is developing automates the work of 
more than 4,250 Child Support Enforcement workers throughout 
Ohio's 88 counties.   In November 1997, the State of Ohio 
awarded the Company a contract for additional computer network 
infrastructure and related services.  DRC continues to provide 
computer hardware and software, site preparation and 
installation, and technical support services for the SACWIS and 
Ohio Works First System that support Ohio's welfare reform 
initiatives.

    In December 1997, DRC 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 is 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.  The 
contract includes options for four additional years of system 
maintenance and support.

    The Company continues to provide the U.S. Department of 
Treasury with information technology services for the Internal 
Revenue Service and other Treasury departments.  Year 2000 
software and system certification projects represent the 
majority of activity under this contract.
    
    Critical to the development of information systems is the 
Company's software development process and related tools.  The 
Company's approach to mission-critical software stresses 
principles of continuous software quality evaluation and 
increased visibility throughout the software development life 
cycle.  To this end, DRC has achieved Level-2 certification 
under the standards of the Software Engineering Institute and 
is actively pursuing Level-3 certification.

Precision Manufactured Products 

    The commercial operations of DRC's Precision Products Group 
consists of two divisions:  Encoder Division and Metrigraphics Division.
   
    DRC's Encoder Division designs, manufactures, and markets a 
line of digital 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 pick-and-place machines.  DRC's digital encoding 
devices are essential elements of today's electronically-
controlled systems and equipment.

    The Encoder Division manufactures an encoder used in engine 
fuel pumps for diesel powered sport utility vehicles, pickup 
trucks and commercial vans.  The encoder is a critical 
component of a computer control system that gauges the amount 
of fuel injected into the cylinders, optimizing usage and 
minimizing the amount of unburned fuel and resultant exhaust 
fumes.

    The Metrigraphics Division uses photolithographic processes to 
manufacture optical discs, scales and reticles that are used 
for precision measurement.  Metrigraphics also uses various 
metal deposition processes, including electroplating and 
electroforming, to produce a variety of precision components.  
Products include printheads and oriface plates used in 
electronic printers and circuitry used in certain medical 
instruments.  Metrigraphics' superior ability to design and 
manufacture components and maintain critical tolerances is an 
important driver for a wide range of high-technology 
applications.

    Metrigraphics' largest market 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

    Since 1996, the Company has been licensed to enhance, market 
and maintain a telecommunications fraud control system 
developed by Pacific Bell Telephone Company.  DRC has 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 
include the regional Bell operating telephone companies.  A 
number of recent changes in the telecommunications marketplace 
have delayed near-term sales goals and increased the estimated 
capital required to take advantage of this expanding market.  
In December 1998, the Company adopted a plan to exit 
this business during 1999.

Software Development Technology

    Over a number of years, DRC has invested in the research and 
development of VisualMagic, an object-oriented development 
environment.  This development environment was useful in the design of
Internet applications.  During 1998, the Company acquired an interest
in Empresa, Inc. (formerly Electronic Press Services Group, Inc.)
in exchange for an exclusive license to VisualMagic in certain fields,
cash and the assets of the business.  Empresa also hired DRC's staff.
DRC does not expect to continue its development of Visual Magic.

    Empresa provides e-commerce solutions for small to medium size 
merchants, banks, and other customers seeking a competitive 
advantage by being on-line.  Empresa's solutions include 
turnkey on-line storefronts and transaction processing 
capabilities highly customized to integrate with a customer's 
existing internal systems and with financial institutions.  

Sales & 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 1998, the Company's revenues from contracts with the
DoD, either as prime contractor or subcontractor, accounted for 
approximately 59% of the Company's total revenues.


    During 1998, the Company's U.S. Government business 
consisted of approximately 101 separate contracts on 16 
different programs.  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 sales and earnings.

    The Company's revenues from contracts with four different states
accounted for approximately 22% of 1998 revenues.  Revenues under
various contracts with the State of Ohio accounted for approximately
13.6% of 1998 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.  In 1998, approximately 58% of the Company's state
and federal government contract revenue was under fixed-price or time and 
material contracts, while approximately 42% of revenue was 
under costs plus fixed-fee contracts.

Backlog

    At December 31, 1998, the Company's backlog of unfilled 
orders was approximately $105.4 million compared with $110.0 
million at December 31, 1997.  The Company expects that 
substantially all of its backlog at December 31, 1998 will be 
filled during the year ending December 31, 1999.  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.

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 $2.7 million (inclusive 
of overhead and other indirect costs) on new product and 
service development during the year ended December 31, 1998, as 
compared to expenditures of $1.2 million during 1997 and $2.2 
million during 1996.

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, 1998, the Company had 1,557 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 333,000 square feet, which are utilized for its 
federal and state government services, manufacturing and 
warehousing 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 29 
locations across the United States.  The Company owns a 135,000 
square foot facility in Andover, Massachusetts that is utilized 
for its defense service operations and corporate administrative 
offices.

    The Company's total rental cost for 1998 was $3.6 million.

    The Company believes its properties are adequate for its

            REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS ON SCHEDULES
                     TO CONSOLIDATED FINANCIAL STATEMENTS


To Dynamics Research Corporation:

    We have audited in accordance with generally accepted 
auditing standards, the consolidated financial statements 
included in Dynamics Research Corporation's annual report to 
shareholders incorporated by reference in this Form 10-K, and 
have issued our report thereon dated February 18, 1999.  Our 
audit was made for the purpose of forming an opinion on those 
statements taken as a whole.  The schedule listed in the 
accompanying index is the responsibility of the company's

the basic financial statements and, in our opinion, fairly 
states in all material respects the financial data required to 
be set forth therein in relation to the basic financial 
statements taken as a whole.


                                            ARTHUR ANDERSEN LLP


Boston, Massachusetts,
February 18, 1999



                                                            Exhibit 99

          IMPORTANT FACTORS REGARDING FORWARD-LOOKING STATEMENTS


The following factors, among others, could cause the Company's 
actual results and performance to differ materially from those 
contained in forward-looking statements made in this report and 
presented elsewhere by or on behalf of the Company from time to 
time.

Uncertainties as to Department of Defense and Other Federal Agency Budgets

     In 1998, approximately 59% of the Company's revenue
was with the DoD and its Services. In the past, the Company's
defense business has been adversely affected by significant changes
in defense spending during periods of declining U.S. defense budgets.
Among the effects of this general decline has been increased
competition within a consolidating defense industry.  It is not possible
for the Company to predict whether defense budgets will increase or 
decline in the future.  Further, changing missions and 
priorities in the defense budget may have adverse effects on 
the Company's business.  Funding limitations could result in a 
reduction, delay, or cancellation of existing or emerging 
programs.  The Company anticipates there will continue to be 
significant competition when the Company's defense contracts 
are rebid as well as significant competitive pressure to lower 
prices, which may reduce profitability in this area of the 
Company's business.  Any reduction in the level or 
profitability of the Company's defense business, if not offset 
by new commercial business or other business, will adversely affect
the Company's business, financial condition and results of operations. 
   
Government Contracting Risks

     The Company has historically derived a substantial portion
of its revenue from contract and subcontracts with the U.S.
Government.  In recent years, the Company has entered into significant
information technology services contracts with various state
governments.  A significant portion of the Company's federal and state
government contracts are of a time and materials nature, with fixed
hourly rates that are intended to cover salaries, benefits, other 
indirect costs of operating the business and profit.  The 
pricing of such contracts is based upon estimates of future 
costs and assumptions as to the aggregate volume of business 
that the Company will perform in a certain business division or 
other relevant unit.  For long term contracts, the Company must 
estimate the costs necessary to complete the defined statement 
of work and recognize revenues or losses in accordance with 
such estimates.  Actual costs may vary materially from the 
estimates made from time to time, necessitating adjustments to 
reported revenue and net income.  Underestimates of the costs 
associated with a project could adversely affect the Company's 
overall profitability and could have a material adverse effect 
on the Company's business, financial condition and results of 
operations.

     A significant portion of the Company's federal and state
government contracts are renewable on an annual basis, or are subject
to the exercise of contractual options.  Multi-year contracts often
require funding actions or other appovals by U.S. Government, state
legislature or others on an annual or more frequent basis.  As a result,
the Company's business could experience material adverse consequences
should such funding actions or other approvals not be taken. 

     Governmental awards of contracts are subject to
regulations and procedures that permit formal protests by 
losing bidders.  Such protests may result in significant delays 
in the commencement of expected contractual effort, or the 
reversal of a previous award decision, which could have a 
material adverse effect on the Company's business, financial 
condition and results of operations.

     Because of the complexity and scheduling of contracting 
with government agencies, from time to time costs are incurred in 
advance of contractual funding.  In some circumstances, such costs may
not be recovered in whole or in part under subsequent contractual
actions.  Failure to collect such amounts may have material
adverse consequences on the Company's business, financial condition
and results of operations.

     Costs incurred in connection with government contracts are 
generally subject to audits.  Such audits may result in 
material disallowances, which could have an adverse effect on 
the Company's  business, financial condition and results of 
operations.

     A substantial portion of the Company's U.S. Government 
business is as a subcontractor.  In such circumstances,
the Company generally bears the risk that the prime
contractor will meet its performance obligations to the U.S.
Government under the prime contract and that the prime 
contractor will have the financial capability to pay the 
Company amounts due under the subcontract.  The inability of a 
prime contractor to perform or make required payments could 
have a material adverse effect on the Company's business, 
financial condition and results of operations.

     The U.S. Government has the right to terminate contracts for 
convenience.  In such a termination, the Company would 
generally recover costs incurred up to termination, costs 
required to be incurred in connection with the termination, and 
a portion of the fee earned commensurate with the work 
performed to termination.  However, significant adverse effects 
on the Company's indirect cost pools may not be recoverable in 
connection with a termination for convenience.  Contracts with 
state and other governmental entities are subject to the same 
or similar risks.
 
Dependence on Key Personnel

     The Company is dependent on its key technical personnel.  
In addition, certain technical contributors may have specific 
knowledge and experience related to various government customer 
operations that would be difficult to replace in a timely 
fashion.  The loss of the services of key personnel could have 
a material adverse effect on the Company's ability to perform 
required services under certain contracts, or to retain such 
business after the expiration of the current contract, or to 
win new business where certain personnel have been identified 
as key personnel in the proposal, any of which could have a 
material adverse effect on the Company's business, financial 
condition and results of operations.  

Competition

     The government contracting business is subject to intense 
competition, both technical and pricing, from numerous 
companies, many of which have significantly greater financial, 
technical and marketing resources than the Company.

     Competition in the market for the Company's commercial 
products is also intense.  There is a significant lead time for 
developing such business, and it involves significant capital 
investment including development of prototypes and investment 
in manufacturing equipment.  The Company's precision products 
business has a number of competitors, many of which have 
significantly greater financial, technical and marketing 
resources than the Company.

Risks Associates with New Markets and New Products

     In its efforts to enter new markets, including Government 
agencies other than the DoD and commercial markets, the Company
faces significant competition from other companies that have
prior experience with such potential customers as well as significantly
greater financial, technical and marketing resources than the Company.
As a result, the Company's efforts to enter such new markets
may not achieve the level of success sought by the Company.

     The Company has licensed its object-oriented software 
technology to a third party and made an investment in that 
company.  There is no assurance that the investee company's 
products and services will meet with market acceptance or that 
they will be able to compete in the development and 
distribution of such products with competitors that have 
significantly greater resources and experience.  Failure to 
operate profitably or to raise new capital, if required, may 
adversely affect the Company's investment.

Concentration of Customers

     Within the DoD, individual services and program offices account
for a significant portion of the Company's Government business.
One state customer accounts for a significant portion of the
Company's revenue.  Two customers account for a significant
portion of the revenue of the Company's commercial manufacturing
divisions.  No assurance can be provided that any of these customers
will continue as such or will continue at current levels.  A decrease
in orders from any of these customers would have an adverse effect
on the Company's profitability, and the loss of any large customer 
could have a material adverse effect on the Company's business, 
financial condition and results of operations.

Risk of Product Claims

     The Company's precision manufactured products are 
generally designed to operate as important components of 
complex systems or products and defects in DRC products could 
cause the customer's product or systems to fail or perform 
below expectations.  Like other manufacturing companies, the 
Company may be subject to claims for alleged performance issues 
related to its products.  There can be no assurance any such 
claims, if made, will not have a material adverse effect on the 
Company's business, financial conditions or results of 
operations.

Risk of Economic Events Effecting the Company's Business Segments

     Certain of the Company's precision products are components 
of commercial products. Factors that affect the production and 
demand for such products, including economic events both 
domestically and in other regions of the world, competition, 
technological change and production disruption, could adversely 
affect demand for the Company's products.  Certain of the 
Company's products are incorporated into capital equipment, 
such as machine tools and other automated production equipment, 
used in the manufacture of other products.  As a result, this 
portion of the Company's business may be subject to 
fluctuations in the manufacturing sector of the overall 
economy.  An economic recession, either in the U.S. or 
elsewhere in the world, could have a material adverse effect on 
the rate of orders received by the commercial divisions.  
Significantly lower production volumes resulting in under-
utilization of the Company's manufacturing would adversely 
affect the Company's business financial condition and results 
of operations.

Technological Change

     The Company's knowledge base and skills in the government 
contracting area are sophisticated and involve areas in which 
there have been and are expected to continue to be significant 
technological change.  There is no assurance that the Company 
will continue to be able to offer services that satisfy its 
customers' requirements at a competitive price.  Many of the 
Company's products are incorporated into sophisticated 
machinery, equipment or electronic systems.  Technological 
changes may be incorporated into competitors' products that may 
adversely affect the market for the Company's products.  
Further, there can be no assurance that the Company's research 
and product development efforts will be successful or result in 
new or improved products that may be required to sustain the 
Company's market position.

Uncertainty of Future Financing

     Although the Company has no immediate plans to raise 
additional capital, in the future it may need to raise 
additional funds through public or private debt or equity 
financing.  There can be no assurance that any such funding 
will be available or of the terms or timing of any such 
funding.

**   As discussed further in Management's Discussion and 
     Analysis, in the fourth quarter of 1998, the Company decided 
     to discontinue operations of its Telecommunications business. 
     Accordingly, the results of operations of this segment have 
     been excluded from revenue, operating income and income from 
     continuing operations in this schedule.


To Our Shareholders

While we recorded a 16 percent increase in revenues and achieved 
healthy growth in most business areas during 1998, it was a 
challenging year for Dynamics Research Corporation (DRC). 
Investments in certain new businesses created a drain on 
operations, leading to an interruption in the growth in net income 
achieved over the past four years. We have moved expeditiously to 
eliminate unprofitable business initiatives and are fully focused 
on resuming our track record of earnings growth in 1999.

Financial Results

Revenues from continuing operations for the year ended December 31, 
1998 increased to $182,344,000 from $156,733,000 in 1997. Income 
from continuing operations was $491,000, or $.06 per diluted share, 
versus $5,177,000, or $.66 per diluted share, last year. 

At the end of 1998, we decided to exit the telecommunications
business. As a result, we incurred an after-tax charge of 
$2,572,000 to provide for the estimated loss on the disposal of 
this business area during 1999. Results for 1997 and 1996 have been 
restated to reflect continuing operations. Included in 1997 results 
is a one-time net income benefit of $1,000,000, or $.16 per share, 
related to a research and development tax credit. Including results 
from discontinued operations, DRC recorded a net loss for 1998 of 
$5,971,000, or $.77 per diluted share.

Sales for the Systems and Test Equipment divisions totaled
$154,336,000, representing 85 percent of revenues, while sales for 
the Precision Manufactured Products divisions equaled $28,008,000. 
One of DRC's long-stated objectives is to diversify its revenue 
base toward a 50/50 balance between defense and non-defense 
business. In 1998, non-defense projects accounted for approximately 
41 percent of sales-up from 34 percent last year. 

New Business Initiatives

One of DRC's strengths is its ability to successfully incubate new 
business initiatives. Outstanding examples include the extension of 
our logistics expertise into new Air Force programs, the rapid 
growth of information technology services for state government 
agencies, and high volume production contracts for our precision 
manufactured devices. 

One of the more exciting technologies we have developed is a
highly advanced object-oriented software development environment 
for Internet applications, known internally as VisualMagic. 
Recognizing that we needed Internet commerce and marketing 
expertise to realize the full commercial potential of this powerful 
tool, at year-end we acquired an interest in Empresa, Inc. 
(formerly Electronic Press Services Group, Inc.) and transferred 
our VisualMagic development staff to the company. 

Based in Cambridge, Massachusetts, Empresa is a privately
held developer of electronic storefronts and the infrastructure 
behind Internet transactions for the financial services and 
publishing industries. We believe this is an excellent opportunity 
to participate in the growth of Internet commerce and look forward 
to reaping the benefits of this transaction in years to come.

DRC's ethic of enabling new ideas to come to the fore has
produced outstanding results. It is inevitable, however, that some 
initiatives won't succeed, or will require a level of investment 
beyond our means. Recently, we announced plans to exit our 
telecommunications fraud control systems business. We arrived at 
this decision after encountering changes in the telecommunications 
marketplace that delayed near-term sales and increased the amount 
of capital required for taking full advantage of this market 
opportunity. 

We will continue to support new concepts and technologies
that have a significant potential for profitable growth, and move 
swiftly to attach ourselves to new markets and technologies where 
there are clear needs for our products and services. We are, 
however, instituting a more rigorous internal screening system for 
scrutinizing and qualifying the payback potential of future growth 
initiatives. 

1998 Growth Drivers 

State Health & Human Services

Providing information technology services for state government
agencies was one of our primary sources of growth in 1998. We 
doubled sales in this area during the year, winning and fulfilling 
major contracts for Colorado's child protection and juvenile 
justice agencies and for a variety of agencies in Ohio. We expect 
to record significant revenues from Colorado and Ohio in 1999 as 
well. In addition to expanding programs within the states we 
currently serve, we are focused on establishing relationships with 
other states. Recently, we won a $1,400,000 contract to support 
Arkansas' child welfare information system, and are bidding on 
projects in additional states. 

Defense Capabilities

Our defense business increased 4 percent in 1998, due to the
expansion of our field offices. One of our most important wins this 
year was an omnibus contract with the U.S. Air Force Aeronautical 
Systems Center at the Wright-Patterson base in Dayton. During the 
year we booked $8,000,000 in new orders under this contract. This 
program is similar to the work we have performed for the Air Force 
Electronics System Center, and is a significant example of our 
ability to expand relationships with existing customers.

Similar to our growing business with the U.S. Air Force Air
Logistics Centers, we are increasing engineering and logistics 
support for the U.S. Army Aviation and Missile Command. Conducted 
primarily out of our Huntsville office, much of our work for the 
Army involves providing engineering and logistics support for the 
Black Hawk and Comanche helicopters, as well as sophisticated 
electronics and communications systems. 

Our Test Equipment Division was awarded a $1,000,000 contract
from Lockheed Martin for tactical communications processing 
software for a system they are developing for the Australian 
Defense Forces. This contract is a validation of the international 
market for our workstation for testing devices that receive and 
synthesize tactical data and positioning information from diverse 
military sources. The systems and test work we perform for the Navy 
on navigation systems for Trident missiles remains a major program 
at DRC.

Commercial Sector Systems & Support Opportunities

Building business in the systems and services area for commercial
customers has been a long-stated goal, and DRC continues to make 
inroads into this sector. Work for commercial clients includes year 
2000 computer system date change test and validation programs for a 
division of the General Electric Company and a New England bank, as 
well as re-engineering work for the manufacturing operations of a 
commercial aircraft equipment company. We have proposals out on 
several similar projects and hope to make good progress on 
expanding our systems business in the commercial arena in 1999. 

Precision Manufactured Products 

Results for the Precision Manufactured Products divisions were
impacted by the Asian financial crisis and a related downturn in 
customer spending on encoder sensor devices for semiconductor and 
other capital equipment. However, we are teaming with product 
development engineers at prospective customer organizations in the 
automotive, medical, high technology and telecommunications sectors 
to create new applications for our encoder and precision 
electroformed devices. We expect to go into mass production with 
several of these devices over the next two years. 

Acquisition Opportunities

Much of our growth over the past five years has been generated
internally. We are also seeking to expand through acquisitions of 
profitable organizations. Criteria for potential acquisition 
targets are that they should offer DRC entree into a new market, 
specific expertise or key people that complement or extend our 
existing business. 

1999 Objectives and Outlook

Our primary objective for 1999 is to resume the earnings growth
trend of the previous four years. We will accomplish this by 
continuing the expansion of our systems and support services into 
U.S. defense agencies, state health and human services divisions 
and the commercial sector. We are looking to increase Metrigraphics 
and Encoder divisions' sales with new high volume products. 

The defense budget has a $12 billion proposed  increase in military
spending for the next fiscal year and $110 billion over six years, 
initiatives that may well contribute to the growth of our defense 
business. Regardless of the outcome of these proposals, there will 
always be a mandate for our armed forces to control costs and 
operate more efficiently. DRC has key capabilities for enabling the 
military to maintain and manage its resources at lower costs, and 
we provide an invaluable repository of knowledge of the evolution 
and operations of large, sophisticated systems.

As always, we have been buoyed along this year by the initiative,
dedication and creativity of our employees. We thank them, and our 
shareholders, for their support.

Sincerely,

Albert Rand
President and
Chief Executive Officer

Transferring Core Competencies into New Markets

Doing superlative work and winning new contracts from existing 
customers is a fundamental aspect of top-line growth at Dynamics 
Research Corporation (DRC). But aggressive growth targets call for 
identifying and branching out into new markets and establishing 
relationships with new customers. 

A hallmark of DRC's success has been its ability to transfer
core ompetencies-disciplines in which it has proven expertise and a 
strong record of success-into entirely new markets or types of 
customers. Core competencies at DRC include providing information 
technology, logistics, engineering, simulation and training 
services for government and commercial customers, and high-
precision device manufacturing for a broad variety of applications.

This strategy of extending core competencies has enabled the
Company to achieve an annual revenue growth rate of more than 20 
percent over the past four years, and has resulted in greater 
diversification.  In 1998, revenues derived from non-defense 
sources represented 41 percent of total revenues, versus 34 percent 
in 1997. In the pages that follow, we focus on only a few of the 
many ways DRC is extending its core competencies into new markets 
and new customers.

        
Extending Expertise into Army Aviation
Core Competency Case Study #1
Logistics and Support

DRC has longstanding expertise in providing logistics and 
engineering services to support the maintenance and combat 
readiness of U.S. Air Force aircraft and Navy weapons systems. In 
1996, DRC broke into a new market as a prime contractor on a five-
year, $33 million contract under a U.S. Army program known as 
Programmatic and Technical Support (PATS). Conducted primarily out 
of Huntsville and Daleville, Alabama, and St. Louis, Missouri 
offices, DRC's work focuses on sustaining the readiness of 
helicopters and fixed-wing aircraft for the U.S. Army Aviation & 
Missile Command headquartered at nearby Redstone Arsenal.

One of the main systems the Company supports is the UH-60
Black Hawk Helicopter, as well as Comanche and Apache Attack 
helicopters. DRC engineers and managers, half of whom are former 
Army helicopter pilots, assess readiness issues, conduct operating 
cost analyses and risk assessments, and provide acquisition 
support. In addition, they analyze design flaws, forecast parts 
availability and determine ways to integrate variant aircraft into 
the fleet to minimize repair and maintenance costs. Because of 
their experience as pilots, DRC engineers are well versed in how 
equipment additions or modifications may affect performance and 
flight characteristics.

DRC also supports the Army Airborne Command and Control
System, a suite of highly sophisticated electronics and 
communications gear installed on some Black Hawks, as well as the 
Tactical Airspace Integration System that helps field commanders 
manage a highly complex battlefield environment. Revenue under the 
PATS contract was approximately $8.5 million in 1998, up from $6.5 
million in 1997. Recently, DRC won an additional subcontract to 
provide logistics and engineering support for the Army Tank, 
Automotive and Armaments Command (TACOM) in Warren, Michigan.


Broadening Health and Human Service Markets
Core Competency Case Study #2
Information Technology

DRC first targeted the burgeoning market for non-defense government 
information technology (IT) services in 1995. Since then, propelled 
by federal legislation that mandates computerized tracking and 
management capabilities at state health and human service agencies, 
DRC's IT business for state governments has grown from $4.5 million 
in revenues in 1996 to more than $40 million in 1998. One of DRC's 
primary growth strategies is expanding its market penetration both 
vertically and horizontally within current customer agencies, into 
other agencies and departments, as well as into new states.

DRC's work for the State of Ohio is an excellent case in
point. Starting initially with a contract to provide computer 
hardware and networks for Ohio's Support Enhancement Tracking 
System, a program that keeps tabs on "deadbeat parents," DRC has 
expanded its work into a variety of departments. These include Ohio 
Works First, a training program for Welfare recipients, the Human 
Resources Management System, which tracks payroll for all state 
employees, and the Division of Acquisition Services. DRC has also 
introduced its logistics and supply chain management capabilities 
into the State government, by providing warehouse and inventory 
management for the Division of Health and Human Services' computer 
equipment and peripherals.

Colorado's Department of Human Services represented a major
portion of DRC's state IT work in 1998. Last June, the Company won 
a contract to assist the State of Arkansas with enhancement of its 
child welfare information system. Proposals are on the table for 
other major contracts with Colorado and Ohio, as well as additional 
states.


Providing Improved Decision Analysis Tools
Core Competency Case Study #3
Simulation and Modeling

Warfare in the Information Age demands that leaders make crucial, 
high-risk decisions consistently and rapidly. An important new 
training tool being developed for the U.S. Army is the Warfighters' 
Simulation 2000, also known as WARSIM 2000. This simulation system 
will support the training of commanders and staff from battalion 
through theater-level.

WARSIM 2000 will provide land warfare information for a joint
services initiative intended to create a common, seamless training 
environment. The system will create a wide variety of battlefield 
scenarios across the spectrum of operations.

Working as a subcontractor to Lockheed Martin, DRC subject
matter experts, engineers and managers comprise more than 17 
percent of WARSIM 2000 development staff, providing leadership and 
expertise in crucial areas.These include software and human factors 
engineering, database development for equipment and knowledge 
acquisition, as well as manpower staffing reduction analysis.

In addition to its work on WARSIM, DRC is carving out a niche
for itself in developing computer simulation models for re-
engineering plant layout for large aircraft equipment repair shops 
for both military and commercial operations. DRC's work in this 
area began by designing computer models that analyze and improve 
the workflow for landing gear repair shops. The Company is 
currently re-engineering a plant layout for an equipment 
manufacturer of commercial and military aircraft, and has proposals 
for similar projects before several other commercial aircraft 
repair facilities.


Developing New Applications
Core Competency Case Study #4
Precision Products

When Motorola-backed Iridium LLC launched the world's first 
satellite-based global wireless telephone and messaging system, it 
tapped DRC's Encoder Division to develop devices that help control 
antenna position for satellite-to-satellite and satellite-to-ground 
station communications. Collaborating closely with Iridium 
engineers, DRC custom designed and assembled devices that precisely 
calibrate and control antenna motion. Today, each of Iridium's 66 
low-orbiting satellites carries 15 DRC encoders. The satellite 
development community looks to suppliers with proven expertise, and 
there are many potential applications for encoder devices. DRC is 
now working on several new satellite antenna-positioning 
applications for its encoder products.

DRC's Encoder Division produces customized electro-mechanical
devices that measure position in a wide range of high technology 
capital equipment requiring high-precision motion control. Today, 
DRC encoders are used in a variety of applications from 
semiconductor manufacturing equipment to automotive diesel fuel 
injection pumps.

This tradition of developing devices in collaboration with
customer teams carries over to DRC's Metrigraphics Division, which 
designs and manufactures high-precision miniature components. 
Metrigraphics' products are created through a process known as 
electroforming, whereby a thin, flexible metal film is deposited on 
glass, metal or other substrates. These devices are incorporated in 
electronic circuitry for heart catheters and ink deposition nozzles 
for consumer and commercial grade ink-jet printers. Currently, a 
variety of new applications are under development, including 
flexible miniature circuits for medical uses, advanced 
semiconductor devices and high-density disk drive components for 
personal computers.


Supporting the Air Force Materiel Command
Core Competency Case Study #5
Technical and Engineering Services

Last spring, DRC won its third major contract with the U.S. Air 
Force Materiel Command, whose mission is to develop, deliver and 
maintain all Air Force systems and equipment. Under this latest 
contract, DRC is providing technical, engineering and 
administrative support for the Aeronautical Systems Center at 
Wright-Patterson Air Force Base in Dayton, Ohio. 

One of the factors contributing to DRC winning the contract
was the work it performs for the Electronic Systems Center at 
Hanscom Air Force Base in Massachusetts and for the Air Logistics 
Centers' five U.S. maintenance depots. Under these earlier 
contracts, DRC supervises the acquisition of advanced radar, 
communications and computer equipment, and the logistics for 
locating and moving repair parts to and among the five depots.

The Aeronautical Systems Center is responsible for research,
development, test, evaluation and initial acquisition of 
aeronautical systems and related equipment for the Air Force. Its 
major active programs are the B-2 and B-1B bombers, C-17 airlifter, 
F-15, F-16 and F-22 fighters, training systems, aircraft engines, 
special operations forces and litigation support.

Two of the programs DRC supports at Wright-Patterson are the
Joint Airborne Signal Intelligence (SIGINT) and Reconnaissance 
Mission Area Group. DRC's team provides systems engineering, 
security management, test and evaluation, acquisition management, 
configuration and data management, and administrative support for 
these programs. Projects include providing hardware and software 
support for SIGINT computer platforms, communications acquisition 
support for encrypted data transfer, and the development of 
electro-optical multi-spectral imagery road maps.

The following comments should be read in conjunction with the
 foregoing table:

Year Ended December 31, 1998 Compared to Year Ended December 31, 1997

Total revenues from continuing operations increased 16.3% to
$182,344,000 for the year ended December 31, 1998 compared with 
$156,733,000 for the year ended December 31, 1997. Contract revenue 
for the systems and service segment increased by 19.5% or 
$25,201,000 in 1998 over 1997. Growth in the systems and services 
segment was principally attributable to performance on two major 
state contracts as well as broad based growth in the Company's 
defense business. The Company is providing the State of Ohio's 
Department of Health and Human Services with statewide computer 
network infrastructure. DRC is providing similar infrastructure, as 
well as software implementation services to the State of Colorado's 
child protection and juvenile justice agencies. Much of the 
Company's revenue relates to the development and operation of 
computer-based management information and logistics support 
systems, as well as other information technology services.

Product sales increased 1.5% or $410,000 in 1998 as compared
with 1997. In 1998, the Company achieved higher sales of 
electroformed components to several customers, including the 
Company's primary customer in the inkjet printer market, and 
increased sales to a customer in the automotive industry. This 
growth was substantially offset by reduced sales of encoders which 
were adversely affected by the Asian financial and economic crisis 
during 1998. 

Cost of contract revenue as a percentage of contract revenue
increased to 91.1% in 1998 from 88.7% in 1997. In the fourth 
quarter of 1998, after a thorough evaluation of program performance 
and negotiations with the customer, the Company recorded a charge 
of $2,600,000 that relates to an estimated overrun on a state 
contract. Also included in the fourth quarter is a charge of 
$1,700,000 to cover certain defense contract overruns and other 
expenses. These charges are all reflected in the systems and 
services segment.

Cost of goods as a percentage of product sales increased from
75.0% in 1997 to 78.7% in 1998. This increase is the result of an 
increase in per unit depreciation expense of certain equipment, 
costs related to the installation of new manufacturing software and 
reductions in encoder sales, offset somewhat by higher sales of 
electroformed components. During 1997, a large customer reduced its 
estimated purchases from DRC. As a result of the reduction in this 
estimate, beginning in the fourth quarter of 1997, management 
increased the per unit depreciation of equipment used to 
manufacture this product. The effect of this change was to increase 
depreciation expense $1,163,000 in 1998 and $219,000 in 1997. 
Included in cost of goods is $887,000 and $979,000 in 1998 and 
1997, respectively, related to effort on the Company's VisualMagic 
software development environment product.

At the end of 1998, the Company adopted a plan to sell the
telecommunications fraud control business unit as the result of 
changes in the telecommunications marketplace that delayed near-
term sales goals and increased the Company's estimate of the 
capital required to take advantage of this market. Accordingly, 
results from the telecommunications business are shown as 
discontinued operations and prior years have been restated to 
conform to this presentation. The total loss from discontinued 
operations includes operating losses incurred through the date on 
which the discontinuance plan was adopted, estimated future 
operating losses through September 1999, as well as other estimated 
costs associated with the disposal of the business. Estimated 
operating losses of $3,487,000 for the period subsequent to the 
adoption of the exit plan through the anticipated date of sale are 
included in the loss on disposal. The results of discontinued 
operations do not reflect any interest expense or any allocation of 
corporate management expense. Revenues of the telecommunications 
business were $2,775,000, $2,644,000 and $166,000 for the years 
ended December 31, 1998, 1997 and December 28, 1996, respectively. 
Net operating losses of the telecommunications business were 
$5,879,000, $1,562,000 and $938,000 for the years ended December 
31, 1998, 1997 and December 28, 1996, respectively. These amounts 
are not included in sales or operating income as reported in the 
Consolidated Statements of Income.

Selling, engineering and administrative expenses increased by
26.3% or $3,580,000 in 1998 from 1997. This increase is the result 
of a number of factors. The increase in revenues generated overall 
growth in corporate, accounting and financial salaries, wages and 
expenses to support the resultant increase in transaction 
processing. During 1998, and to a lesser extent in 1997, the 
Company realized an increase in consulting expenses and temporary 
labor related to accounting system changes. During 1998, the 
systems and services segment expended a significant amount of 
effort on developing a new software product for sale to the U.S. 
Air Force and other defense contractors. Included in selling, 
engineering and administrative expenses is $972,000 and $1,029,000 
in 1998 and 1997, respectively, related to the VisualMagic selling 
effort.

In the fourth quarter of 1998, the Company entered into an
agreement with Empresa, Inc. (Empresa), formerly Electronic Press 
Services Group, Inc., to acquire an interest in Empresa in exchange 
for a perpetual license to VisualMagic, cash and the assets of the 
business. The terms of the agreement provide for the Company to 
make three cash investments: one at the closing December 23, 1998, 
the second in February 1999 and the last in May 1999.

Interest expense, net, increased to $1,612,000 in 1998 from
$108,000 in 1997 as a result of the Company's higher average 
borrowing in 1998. Interest expense in 1997 benefited from an 
interest credit of $740,000 related to a refund of federal taxes. 
Substantial revenue growth and delays in billing certain state 
customers in 1998 were the principal factors requiring higher 
working capital that was funded with additional borrowing. Capital 
expenditures in 1998 of $3,171,000 consist mainly of spending on 
information technology equipment, office facilities and 
manufacturing equipment.

The provision for income taxes was 42.0% of income from
continuing operations before taxes in 1998, compared to 32.8% in 
1997. The Company's 1997 tax provision reflects a one-time benefit 
of $747,000 resulting from a refund of income taxes relating to 
prior years' research and development expenses.

The Company's backlog of unfilled orders at the end of 1998
decreased 4.2% to $105,427,000 compared to $110,001,000 at the end 
of 1997. The 1997 balance included a $28,300,000 state contract 
award with a 2 1/2 year period of performance. A portion of the 
Company's backlog is based on annual purchase contracts and the 
amount of the backlog as of any date can be affected by the timing 
of such order receipts and deliveries thereunder.

Year Ended December 31, 1997 Compared to Year Ended December 28,1996

Total revenues from continuing operations increased 20.6% to
$156,733,000 for the year ended December 31, 1997 compared to 
$129,997,000 for the year ended December 28, 1996. Approximately 
60% of the increase in the systems and services segment contract 
revenue is attributable to the major contracts with the states of 
Ohio and Colorado, discussed above. The remainder of the increase 
was broad-based with growth contributions from additional work 
received under the Company's long running core Navy program, 
technical and management services programs for the U.S. Army, Air 
Force and Navy and services for the U.S. Department of the 
Treasury. 

Product sales decreased 5.8% to $27,598,000 for the year
ended December 31, 1997 compared to $29,285,000 for the year ended 
December 28, 1996. The decrease is principally the result of 
decreased sales of electroformed components, partially offset by 
increased sales of custom encoders.

Cost of contract revenue as a percentage of contract revenue
decreased to 88.7% in 1997 from 90.8% in 1996. In the fourth 
quarter of 1996, the Company incurred a pre-tax charge of 
$1,800,000 for unrecoverable costs associated with an Air Force 
contract.

Cost of goods as a percentage of product sales increased from
69.9% in 1996 to 75.0% in 1997. The decreased gross margin 
percentage is primarily the result of lower sales of electroformed 
components. Included in cost of goods is $979,000 and $2,095,000 in 
1997 and 1996, respectively, related to effort on the Company's 
VisualMagic software development environment product.

Selling, engineering and administrative expenses as a
percentage of revenues decreased from 10.6% in 1996 to 8.7% in 
1997, reflecting a minimal decrease in overall expenditures while 
revenues grew 20.6%. Included in selling, engineering and 
administrative expenses is $1,029,000 and $0 in 1997 and 1996, 
respectively, related to the VisualMagic selling effort.

Interest expense, net, decreased 80.3% to $108,000 in 1997
from $547,000 in 1996. Included in 1997 net interest expense is 
interest income of $740,000 related to an income tax credit 
received during the year, partially offset by increased interest 
expense resulting from an increase in the Company's average 
borrowing level. Capital expenditures decreased to $5,104,000 in 
1997 compared to $9,266,000 in 1996. Included in 1996 capital 
expenditures are approximately $4,900,000 to increase 
electroforming manufacturing capacity. In January 1996, the Company 
acquired the local operations of a defense services business for 
$2,000,000.

The Company's effective tax rate for 1997 was 32.8% compared
to 38.2% for 1996. As discussed previously, the Company's 1997 tax 
provision reflects a one-time benefit of $747,000 resulting from a 
refund of income taxes related to prior years' research and 
development credits.

The Company's backlog at the end of 1997 was $110,001,000
compared with $73,200,000 at the end of 1996 reflecting the 
December 1997 award of a $28,300,000 contract with the State of 
Colorado. 

Liquidity and Capital Resources

During 1998, the Company's primary source of liquidity has been its
revolving credit facility. Working capital requirements, primarily 
related to the substantial increase in sales and delays in billing 
certain government customers, have been funded with additional 
borrowings under the Company's credit facility. Working capital 
increased to $39,223,000 at December 31, 1998 from $27,394,000 at 
December 31, 1997. This increase was primarily attributable to 
increases in receivables. Debt increased $16,800,000 to $26,800,000 
to support the increase in working capital. The Company spent 
$2,272,000 during 1998 for the purchase of treasury shares compared 
with $768,000 during 1997.

At December 31, 1998, $13,200,000 was available for working
capital purposes under the Company's revolving credit facility.

The Company believes that its current assets, cash flow from
operations and available bank lines of credit will be sufficient to 
support its normal operating and capital requirements for 1999. The 
Company did not have any significant capital commitments at 
December 31, 1998 outside the ordinary course of business.

Impact of Inflation and Changing Prices

Overall, inflation has not had a material impact on the Company's
operations. In addition, the terms of Defense contracts, which 
accounted for approximately 59% of the Company's revenues in 1998, 
are generally for one year and include salary increase factors for 
future years, thus reducing the potential impact of inflation on 
the Company.

Year 2000 Disclosure

Many existing computer programs use only two digits, rather than
four, to represent a year. Date-sensitive software or hardware 
written or developed in this fashion may not be able to distinguish 
between 1900 and 2000, and programs written in this manner that 
perform arithmetic operations, comparisons or sorting of date 
fields may yield incorrect results when processing a Year 2000 
date. This Year 2000 problem could potentially cause system 
failures or miscalculations that could disrupt operations.


The Company's State of Readiness
The Company is in the process of identifying and remediating Year 
2000 issues in four areas: (i) information technology ("IT") and 
financial systems, (ii) non-IT systems, (iii) third-party vendors 
and suppliers and (iv) systems it has implemented and maintains for 
various customers. The Company believes its IT and non-IT systems 
will be Year 2000 compliant by the end of 1999.

The Company has completed a review of its financial and other
significant IT systems and is in the process of remediating 
identified material Year 2000 problems. The primary required 
hardware and operating system platform upgrade was completed in 
February 1999. Necessary application upgrades or remediation and 
testing are expected to be completed by mid-1999. The Company also 
conducted a review of all its other computers earlier in 1998 
(including desktops, servers and mainframes) and has addressed all 
material Year 2000 problems. The Company's computer and equipment 
vendors have been contacted to verify Year 2000 compliance. Based 
on their responses, products requiring replacement or upgrade are 
expected to be Year 2000 compliant by mid-1999. In the case of 
third party licensed commercial off-the-shelf products, the Company 
has determined that they are either Year 2000 compliant or the 
licensor has released a compliant version that the Company will 
migrate to by mid-1999. While the Company expects that all 
financial and significant IT-related systems will be Year 2000 
compliant by mid-1999, there can be no assurance that corrective 
actions will be completed in a timely manner.

The Company has completed a full review of all process
control components, including safety equipment, in manufacturing 
and production facilities. Currently, the Company is in the process 
of upgrading or replacing certain components of the phone, 
security, building access, HVAC and lighting systems, which is 
expected to be completed by mid-1999. The Company anticipates that 
all other process control components will be Year 2000 compliant by 
mid-1999. However, there can be no assurance that such upgrades and 
replacements will occur in a timely manner.

The Company requested Year 2000 compliance information from
its employee benefit service suppliers and received responses from 
all suppliers in early 1999. The Company is currently aware of one 
supplier that has a Year 2000 compliance issue and is working 
toward a resolution of such issue by mid-1999. The Company is also 
in the process of developing Year 2000 questionnaires to be sent to 
its major power, energy and communications service suppliers 
beginning in early 1999. The Company expects to have addressed all 
Year 2000 issues with third party suppliers by mid-year 1999. The 
Company has contacted its suppliers of financial services regarding 
computer interface changes and has requested the status of their 
Year 2000 programs, if this information is not readily available on 
their web-sites. Any necessary interface upgrades are expected to 
be completed by mid-1999, although the completion of such upgrades 
in a timely manner depends upon the readiness and willingness of 
suppliers to cooperate and provide this information in a timely 
manner, and cannot be assured. However, the Company intends to 
identify and prioritize critical suppliers and communicate with 
them regarding their plans and progress in addressing Year 2000 
issues.

The Company is in the process of completing its Year 2000
remediation, validation testing and implementation activities for 
systems it had previously implemented and has continued to maintain 
for various customers. This process was completed and tested in 
early 1999. The Company previously developed and marketed 
commercial off-the-shelf products which are currently Year 2000 
compliant.

The Company's Year 2000 Risk

Based on the efforts described above, the Company currently
believes that its systems will be Year 2000 compliant in a timely 
manner. The Company has completed the process of identifying Year 
2000 issues in its IT and non-IT systems and expects to complete 
any remediation efforts by mid-1999. However, there can be no 
assurance that all Year 2000 problems will be successfully 
identified, or that the necessary corrective actions will be 
completed in a timely manner. Failure to successfully identify and 
remediate Year 2000 problems in critical systems in a timely manner 
could have a material adverse effect on the Company's results of 
operations, financial position or cash flow.

In addition, the Company believes that there is risk relating
to significant service suppliers' failure to remediate their Year 
2000 issues in a timely manner. Although the Company is 
communicating with its suppliers regarding the Year 2000 problem, 
the Company does not know whether these suppliers' systems will be 
Year 2000 compliant in a timely manner. If one or more significant 
suppliers are not Year 2000 compliant, this could have a material 
adverse effect on the Company's results of operations, financial 
position or cash flow.

The Company's Contingency Plans

The Company intends by mid-year 1999 to develop contingency plans
to be implemented in the event planned solutions prove ineffective 
in solving Year 2000 compliance. If it were to become necessary for 
the Company to implement a contingency plan, it is uncertain 
whether such plan would succeed in avoiding a Year 2000 issue which 
may otherwise have a material adverse effect on the Company's 
results of operations, financial position or cash flow.

The Company's Costs of Year 2000 Remediation

The Company anticipates the total identified cost of its Year 2000
effort will be between $380,000 and $475,000, of which it has 
expensed approximately $148,000 as of December 31, 1998. The 
estimate excludes labor costs which predated the formal corporate 
Year 2000 effort and certain current labor costs at the divisional 
level which would be difficult to track. The total cost estimate 
includes estimated and actual amounts to remediate or replace 
certain software, routers, security chips, the phone system and any 
other items or systems identified in the Year 2000 effort, 
consulting fees for a Year 2000 review, and approximately $200,000 
of redeployed labor expense. The total estimated cost of redeployed 
labor within the corporate information systems department is equal 
to approximately 9% of that department's total maintenance labor 
budget through the end of the Year 2000 effort. There can be no 
assurance that the costs associated with the Year 2000 problem will 
not be greater than anticipated. The Company has deferred a 
financial and project accounting system upgrade due to its Year 
2000 efforts, but does not believe such deferral will have a 
material adverse effect on the Company's business.

Forward-Looking Information

This report includes certain forward-looking statements about the
Company's business including the effect of the federal budget on 
the Company's sales, response to the Company's product and services 
offerings, growth in revenues, expected performance under certain 
contracts, capital spending, research and development spending and 
customer mix. Such forward-looking statements are subject to risk 
and uncertainties that could cause the actual results to vary 
materially. These risks and uncertainties, discussed in more detail 
in the Company's Form 10-K for the year ended December 31, 1998, 
include possible reductions in federal and state funding for the 
Company's customers and potential customers, concentration of 
customers, risks of sustaining existing contracts and orders 
thereunder at the same or increasing levels and obtaining of new 
contracts, high levels of competition and difficulties of entering 
new markets, government contracting issues including audit 
adjustments and costs of completing fixed price contracts, supply 
difficulties, warranty claims, and factors affecting the business 
segments in which the Company operates and the economy generally.

Notes to Consolidated Financial Statements

1. Nature of the Business and Summary of Significant Accounting Policies

Nature of the Business

Founded in 1955, Dynamics Research Corporation ("the Company" or
"DRC") develops and operates computer and communications-
intensive information systems, provides engineering, management 
support and information technology services, and produces precision 
manufactured components for industrial measurement and control.

Principles of Consolidation

The accompanying consolidated financial statements include the
accounts of Dynamics Research Corporation and its wholly-owned 
subsidiaries. All material intercompany transactions and balances 
have been eliminated in consolidation.

Revenue Recognition and Unbilled Expenditures and Fees on Contracts in Process

The Company provides services under fixed-price, cost-
reimbursement, time and material, and level of effort contracts. 
Revenues under cost-reimbursement and fixed-price contracts are 
recognized as costs are incurred and include applicable fees in the 
proportion that costs incurred bear to total estimated costs. When 
a loss is indicated on any contract in process, provision for the 
total estimated loss is made at that time. For time and material 
and level of effort types of contracts, revenues are recorded as 
the costs are incurred. Unbilled expenditures and fees on contracts 
in process represent the recoverable amounts of contract revenue 
under contracts in process which were not billable at the balance 
sheet date. Such amounts generally become billable upon completion 
of a specific phase of the contract, negotiation of contract 
modifications, completion of government audit or upon acceptance by 
the government. Unbilled expenditures and fees on contracts in 
process with the U.S. Government at December 31, 1998 were 
$18,230,000 compared to $26,083,000 at December 31, 1997, and 
$16,904,000 at December 28, 1996. Unbilled expenditures and fees on 
contracts in process with state governments were $12,833,000, 
$2,839,000 and $469,000 at December 31, 1998 and 1997 and December 
28, 1996, respectively. Costs related to certain contracts, 
including applicable indirect costs, are subject to audit by the 
U.S. Government. Revenues from such contracts have been recorded at 
amounts expected to be realized upon final settlement. Overhead and 
general and administrative costs charged to U.S. Government 
contracts are subject to audit for years after 1996.

Revenue from sales of precision products is recorded at the
time the goods are shipped or when title passes.


Income Taxes

The Company accounts for income taxes using the liability method as
set forth in Statement of Financial Accounting Standards No. 109 
(SFAS No. 109), "Accounting for Income Taxes." Under the 
liability method, deferred taxes are determined based upon the 
difference between the financial statement and tax bases of assets 
and liabilities using enacted tax rates in effect in the years in 
which the differences are expected to reverse. The deferred tax 
provision represents the change in the deferred tax asset/liability 
balance.

Cash and Cash Equivalents

The Company considers all cash investments with original maturities
of three months or less to be cash equivalents.

U.S. Government Contracts

The approximate number of U.S. Government contracts has varied
between 100 and 150 during the past five years, with 101 contracts 
open at December 31, 1998. Receivables under U.S. Government 
contracts at December 31, 1998 were $18,508,000 compared to 
$8,808,000 at December 31, 1997, and $14,363,000 at December 28, 
1996.

Inventories

Inventories are stated at the lower of cost (first-in, first-out)
or market, and consist of materials, labor and overhead. There are 
no amounts in inventories relating to contracts having production 
cycles longer than one year.
                                1998        1997         1996
(in thousands of dollars)
Work in process              $   475    $  1,364     $  1,411
Raw materials and
 subassemblies                 2,172       2,013        1,800
        Total                $ 2,647    $  3,377     $  3,211

Property, Plant & Equipment

Property, plant and equipment are recorded at cost. Depreciation
and amortization are provided in amounts sufficient to amortize the 
cost of such assets over their estimated useful lives using 
principally the straight-line method for plant and equipment. 
Certain manufacturing equipment is depreciated under a units of 
production method. Late in 1997, based on a reduced estimate of 
future purchases by certain customers, management increased the per 
unit depreciation charge accordingly. The result of this change in 
estimate was to increase depreciation expense by approximately 
$1,163,000 during 1998. The effect upon 1997 depreciation expense 
was to increase depreciation expense $219,000. Leasehold 
improvements are amortized over the remaining term of the lease or 
the life of the related asset, whichever is shorter.

Fair Value of Financial Instruments

SFAS No. 107, "Disclosure About Fair Value of Financial
Instruments," requires certain disclosures regarding the fair 
value of financial instruments. Cash and cash equivalents, accounts 
receivable, unbilled expenditures and fees on contracts in process, 
accounts payable and accrued liabilities are reflected in the 
consolidated financial statements at fair value because of the 
short-term maturity of these instruments. The fair value of long-
term debt approximates carrying value as the debt bears interest at 
a variable market rate.

New Accounting Pronouncements

The Company adopted SFAS No. 130, "Reporting Comprehensive
Income," in the first quarter of 1998. SFAS No. 130 requires the 
reporting and presentation of comprehensive income. The adoption of 
SFAS No. 130 did not have a material effect on the Company's 
financial statements.
DRC adopted SFAS No. 132, "Employers' Disclosures about Pensions 
and Other Postretirement Benefits" during 1998. Note 4, Employee 
Benefit Plans, includes the disclosures required under 
SFAS No. 132.

Reclassifications

Certain prior period amounts have been reclassified to conform to
the current year presentation.

Use of Estimates

The preparation of financial statements in conformity with
generally accepted accounting principles requires management to 
make estimates and assumptions that affect the reported amounts of 
assets and liabilities and disclosure of contingent assets and 
liabilities at the date of the financial statements and the 
reported amounts of revenues and expenses during the reporting 
period. Actual results could differ from those estimates.

Stock-Based Compensation

The Company accounts for its stock-based compensation plans under
Accounting Principles Board Opinion No. 25, "Accounting for Stock 
Issued to Employees." SFAS No. 123, "Accounting for Stock-Based 
Compensation" establishes a fair value based method of accounting 
for stock-based compensation plans. The Company adopted the 
disclosure alternative under SFAS No. 123, which requires the 
presentation of the pro forma effects on earnings and earnings per 
share as if SFAS No. 123 had been adopted, as well as the 
disclosure of certain other information. See Note 6, Stock Option 
Plans, for required disclosures.

Net Income Per Common Share

SFAS No. 128, "Earnings per Share," requires the computation of
basic and diluted earnings per share. Basic earnings per share is 
computed by dividing net income by the weighted average number of 
shares of common stock outstanding during the year. Diluted 
earnings per share is determined by giving effect to the exercise 
of stock options using the treasury stock method.

2. Discontinued Operations

Since 1996, the Company has been licensed to enhance, market and 
maintain a telecommunications fraud control system developed by 
Pacific Bell Telephone Company. DRC has 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 include the regional Bell operating 
telephone companies. A number of recent changes in the 
telecommunications marketplace have delayed near-term sales goals 
and increased the estimated capital required to take advantage of 
this expanding market. After careful analysis, management proposed 
to the Board of Directors that the Company exit the 
Telecommunications business. In December 1998, with the Board's 
approval, the Company adopted an overall plan of disposal. The plan 
of disposal includes estimated operating losses through September 
1999, and proceeds from the sale of the business. Accordingly, 
results from the Telecommunications business are shown as 
discontinued operations and prior years are restated to conform to 
this presentation. Estimated operating losses of $3,487,000 for the 
period subsequent to the adoption of the exit plan through the 
anticipated date of sale are included in the loss on disposal. The 
results of discontinued operations do not reflect any interest 
expense or any allocation of corporate management expense. Revenues 
of the Telecommunications business were $2,775,000, $2,644,000 and 
$166,000 for the years ended December 31, 1998, 1997 and December 
28, 1996, respectively. Net operating losses of the 
Telecommunications business were $5,879,000, $1,562,000 and 
$938,000 for the years ended December 31, 1998, 1997 and December 
28, 1996, respectively. The consolidated financial statements of 
DRC have been restated to reflect the discontinuation of the 
Telecommunications business. Accordingly, the revenues, costs and 
expenses, assets and liabilities and cash flows of the 
Telecommunications business have been excluded from the respective 
captions in the Consolidated Statements of Operations, Consolidated 
Balance Sheets and Consolidated Statements of Cash Flows, and have 
been reported as "Loss from discontinued operations," net of 
applicable income taxes; as "Net liabilities (assets) of 
discontinued operations," and as "Net cash used for discontinued 
operations" for all periods presented.

4. Employee Benefit Programs

The Company has a noncontributory defined benefit pension plan 
covering substantially all of its employees. Pension plan benefits 
are generally based on years of service and compensation during 
final years of employment. The Company's funding policy is to 
contribute at least the minimum amount required by the Employee 
Retirement Income Security Act of 1974 or additional amounts to 
assure that plan assets will be adequate to provide retirement 
benefits. Contributions are intended to provide not only for 
benefits attributed to service to date, but also for those expected 
to be earned in the future.

Net periodic pension cost included the following components:

                                              1998        1997        1996

Plan assets consist primarily of equity and fixed income 
securities. Fluctuations in the fair market value of plan assets 
will affect pension expense in future years.

The Company has established a Supplemental Executive
Retirement Plan ("SERP") for a certain key employee providing for 
annual benefits commencing on the sixth anniversary of the 
Executive's retirement. The cost of these benefits is being charged 
to expense and accrued using a projected unit credit method. 
Expense related to this plan was $0 and $203,000 for the years 
ended December 31, 1998 and 1997, respectively.

The Company maintains a cash or deferred savings plan (401(k)
plan), under which employees may reduce their compensation and have 
such "elective deferrals" contributed to the plan on their 
behalf. The Company contributes to the plan an amount equal to 25% 
of the first 6% of an employee's elective deferrals. The Company 
contributed $882,481 to the plan for 1998, $719,099 for 1997 and 
$634,462 for 1996. The elective deferrals are invested in one or 
more collective investment funds at the participant's direction. 
The Company's contributions are invested in guaranteed investment 
contracts and are paid to the employee upon termination, subject to 
forfeiture of any non-vested portion if termination occurs within 
the first five years of employment.

5. Lines of Credit and Long-Term Debt

Long-term debt at December 31, 1998 and 1997 and December 28, 1996 
consists of the following:

                                             1998        1997        1996

The Company amended its existing long-term credit agreement 
with a syndicate of banks and financial institutions during 1998. 
The amended agreement provides an unsecured working capital loan of 
up to $40 million. The agreement expires in October 2000 and is 
renewable annually. Interest on outstanding balances is at the 
prime rate plus an applicable margin or, at the Company's option, 
LIBOR rate plus an applicable margin based upon the Company's debt 
coverage ratio. A fee of 0.375% is assessed upon any unused portion 
of the credit line. The agreement subjects the Company to various 
financial covenants, including maintaining a minimum tangible net 
worth as well as cash flow and debt coverage ratios.

The mortgage note payable to a bank was secured by certain
land and buildings and was paid in full in May 1997. The mortgage 
bore interest at LIBOR plus 1%, adjusted quarterly, and was due in 
quarterly payments of $300,000.

The Company had unsecured lines of credit at December 28,
1996, with various banks that provided for maximum borrowings of 
$19,000,000, of which $10,600,000 was utilized. Borrowings under 
these lines of credit were payable upon demand with interest at the 
prevailing prime interest rate or at a lower rate quoted by the 
respective banks.

The Company's average interest rate on outstanding borrowings
at December 31, 1998 and 1997 and December 28, 1996 was 8.0%, 6.4% 
and 6.3%, respectively.

6. Stock Option Plans

The Compensation Committee of the Board of Directors administers 
the Company's stock option plans and determines the employees who 
will receive options as well as the number and exercise price of 
each such option.

The 1993 Equity Incentive Plan permits the Company to grant
stock options, stock appreciation rights, awards of nontransferable 
shares of restricted common stock and deferred grants of common 
stock. Options also remain outstanding under the Company's 1983 
Stock Option Plan, which terminated in 1993. Options granted under 
both plans may be either incentive stock options or non-qualified 
stock options. The option price may not be less than the fair 
market value at the date of grant in the case of incentive stock 
options, and the option period may not exceed 10 years from the 
date of grant. Options granted under the plans are generally 
exercisable in three equal installments commencing one year from 
the date of the grant.

The Company's 1995 Stock Option Plan for Non-Employee
Directors provides for each outside director to receive options to 
purchase 5,000 shares of Common Stock at the first annual meeting 
at which such director is elected, and options to purchase 1,000 
shares of Common Stock at each annual meeting thereafter so long as 
he or she remains an eligible director. Such directors cannot be an 
employee of the Company or one of its subsidiaries or a holder of 
five percent or more of the Company's Common Stock. The exercise 
price of such options is equal to the fair market value of the 
Common Stock on the date of grant. Each option is non-transferable 
except upon death, expires 10 years after the date of grant and 
becomes exercisable in three equal installments on the first, 
second and third anniversary of the date of grant. A total of 
132,000 shares has been reserved for issuance of which 89,040 
shares remained available at December 31, 1998.

Transactions involving the plans are summarized as follows:*

                             1998              1997            1996

l998.

The Company has computed the pro forma disclosures required
under SFAS No. 123 for options granted subsequent to December 31, 
1994 using the Black-Scholes option pricing model prescribed by 
SFAS No. 123.

Options to purchase 99,800 shares were granted in 1998 with a 
weighted average fair value of $6.75 and options to purchase 71,220 
shares were granted in 1997 with a weighted average fair value of 
$5.92. Options to purchase 183,480 shares were granted in 1996 with 
a weighted average fair value of $4.71.

The Company accounts for the Stock Option Plan under APB
Opinion No. 25 under which no compensation cost has been 
recognized. Had compensation costs for these plans been determined 
consistent with SFAS No. 123, the Company's net (loss) income and 
net (loss) income per share would have been reduced to the 
following pro forma amounts:
                                            1998        1997        1996

Because the SFAS No. 123 method of accounting has not been 
applied to options granted prior to January 1, 1995, the resulting 
pro forma compensation cost may not be representative of that to be 
expected in future years.

7. Commitments and Contingencies

The Company conducts certain of its operations in facilities which 
are under long-term operating leases expiring at various dates 
through 2004, with various options to renew through 2005. It is 
expected that in the normal course of business, leases that expire 
will be renewed or replaced. Rent expense under these leases 
(exclusive of real estate taxes, and insurance) was approximately 
$3,589,000 in 1998, $2,524,000 in 1997, and $2,130,000 in 1996. The 
aggregate minimum lease commitment for the Company's facilities on 
December 31, 1998 was $9,964,000, payable as follows: $3,445,000 in 
1999, $2,719,000 in 2000, $1,508,000 in 2001, $1,207,000 in 2002, 
$848,000 in 2003 and $237,000 in 2004.

8. Preferred Stock Purchase Rights

During 1998, the Company renewed its Shareholder Rights Plan, which 
expired July 27, 1998. Pursuant to this renewal, on February 17, 
1998, the Company declared a dividend distribution of one preferred 
stock purchase right (Right) for every outstanding share of common 
stock, effective July 27, 1998. The Rights attach to all 
outstanding shares of common stock, and no separate Rights 
certificates will be issued. The Rights will become exercisable 
upon the tenth business day following the earlier of (i) the date 
of a public announcement that a person or group of affiliated or 
associated persons has acquired, or obtained the right to acquire, 
beneficial ownership of 15% or more of the outstanding shares of 
common stock of the Company, or (ii) the commencement or 
announcement of an intention to make a tender offer or exchange 
offer that would result in a person or group owning 15% or more of 
the outstanding common stock of the Company.

When exercisable, each Right entitles the registered holder
to purchase from the Company one twelfth of a share of its Series B 
Participating Preferred Stock, $.10 par value, at a price of $54.17 
per each one twelfth share of preferred stock. Until a Right is 
exercised, the holder thereof, as such, will have no rights as a 
shareholder of the Company including, without limitation, the right 
to vote or to receive dividends. Under certain circumstances, each 
share of the Series B Participating Preferred Stock would be 
convertible into a number of shares of the Company's common stock 
having a value equal to twice the exercise price of the preferred 
stock purchase right. The Rights may be redeemed by the Company at 
the discretion of the Board of Directors, at a price of $.0083 per 
Right. The Rights expire on July 27, 2008. The terms of the current 
Shareholder Rights Plan are substantially the same as those of the 
former plan, with the exception that under the former plan, a right 
entitled the registered holder to acquire one-tenth of a share of 
Series A Participating Preferred Stock, $.10 par value, at a price 
of $40.00 per each one-tenth share.

9. Acquisition

On January 23, 1996 the Company acquired the Massachusetts-based 
operations of Support Systems Associates, Inc. (SSAI), a private 
company headquartered in Hauppauge, New York. The Company paid 
$2,000,000 in cash for the acquired business, which had revenue of 
approximately $5,900,000 in 1995. The acquired assets included a 
prime contract to provide services to the U.S. Air Force. In 
January 1997, the Company made additional payments of $250,000 to 
SSAI based upon the achievement of certain thresholds as provided 
in the acquisition agreement. The acquisition was accounted for as 
a purchase. The excess of the purchase price over the fair market 
value of the net assets acquired was amortized over 30 months, and 
was fully amortized at December 31, 1998.

10. Business Segments

The Company adopted SFAS No. 131, "Disclosures about Segments of 
an Enterprise and Related Information," during the fourth quarter 
of 1998. SFAS No. 131 establishes standards for reporting 
information about operating segments in annual financial statements 
and requires selected information about operating segments in 
interim financial reports issued to stockholders. It also 
establishes standards for related disclosure about products and 
services, and geographic areas. The Company has five reportable 
segments: Systems and Services, Metrigraphics, Encoder, Visual 
Magic and Telecommunications. Each of the segments represents a 
separate product line, has different customer requirements and 
production processes and they operate in different industries. The 
Systems and Services segment is the aggregation of two divisions 
that provide similar services to the Department of Defense and 
operate in the same regulatory environment.

The segments follow the same accounting policies described in
Note 1, Summary of Significant Accounting Policies. Certain general 
and administrative expenses, including provisions for doubtful 
accounts and legal expenses, are recorded as corporate expenses 
when recognized and are only included in segment profit or loss 
when amounts are written off or paid. The Company evaluates 
performance based upon profit or loss before interest and taxes. 
Intersegment sales represent less than 1% of total revenues and are 
accounted for at cost. Revenues are attributed to geographic areas 
based upon the customer's location. The Company does not have 
locations outside the United States, but does contract with sales 
representatives located in foreign countries and DRC employees and 
subcontractors provide services at customer locations outside the 
U.S. Domestic revenues represent 91.1%, 91.1% and 98.8% of revenue 
from continuing operations in 1998, 1997 and 1996, respectively.

Systems and Services

The Systems and Services segment provides specialized technical
services to the Department of Defense, federal agencies, state 
governments and other customers and produced approximately 83% of 
total Company revenues in 1998. These services include engineering 
services, development and operation of computer-based management 
systems and other management services. The Systems and Services 
segment provides network infrastructure for state human services 
systems as well as software system implementation services. 

Metrigraphics

The Metrigraphics Division uses photolithographic and material
deposition processes to manufacture optical discs, scales and 
reticles that are used for precision measurement. Metrigraphics 
produces a variety of precision components including printheads and 
orifice plates used in electronic printers and fine line circuits 
used in certain medical instruments. 

Encoder

The Encoder Division designs, manufactures and markets a line of
digital 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 systems, engine fuel-control systems, packaging equipment 
and other capital equipment. Encoder's digital encoding devices are 
essential elements of today's electronically controlled systems and 
equipment. 

Telecommunications

Since 1996, the Company has operated under an exclusive license to
enhance, develop and market a telephone fraud-detection control 
system. Telecommunications customers include five regional Bell 
operating companies. As discussed further in Note 2, Discontinued 
Operations, during 1998 the Company adopted a plan to exit the 
Telecommunications business.

VisualMagic

Over a number of years, DRC has invested in the research and
development of VisualMagic, an object-oriented development 
environment. This development environment has proven to be 
especially useful in the design of Internet applications. As 
discussed further in Note 11, during 1998, the Company acquired an 
interest in Empresa, Inc., formerly Electronic Press Services 
Group, Inc., in exchange for a license to VisualMagic, cash and the 
assets of the segment. Empresa also hired most of the segment's 
employees.

Identifiable assets by business segment include both assets
directly identified with those operations and an allocable share of 
jointly used assets.

Summarized financial information by business segment for 1998, 1997
and 1996 are as follows:

1  As discussed in Note 2, Discontinued Operations, in 1998 
   the Company adopted a plan to sell the Telecommunications 
   business during 1999. Accordingly, the results of the 
   Telecommunications unit are presented as discontinued 
   operations in the consolidated statement of operations. Total 
   1998 Telecommunications results exclude the estimated loss on 
   the disposal of the business. 
2  Net sales and operating profit are presented after the 
   elimination of intersegment transactions.

General corporate assets consist primarily of cash and the 
Company's Andover, MA corporate headquarters.

One customer accounted for 13.6%, 11.3% and 0% of total
revenue from continuing operations in 1998, 1997 and 1996, 
respectively. During 1998, 1997 and 1996, revenues from Department 
of Defense (DoD) customers represent approximately 59%, 66% and 74% 
of total revenues from continuing operations, respectively. 
Revenues earned from one significant DoD contract represent 13.6%, 
17.7% and 21.4% of revenues from continuing operations in 1998, 
1997 and 1996, respectively.

11. Investment in Empresa, Inc.

On December 23, 1998, the Company agreed to make an investment in 
Empresa, Inc., a privately held company based in Cambridge, 
Massachusetts, engaged in electronic commerce services. DRC 
contributed a perpetual license to the VisualMagic development 
environment, the assets of the VisualMagic segment and cash. The 
cash contributions were made in December 1998 and February 1999 and 
a third payment will be required in May 1999, subject to 
achievement of certain performance requirements. DRC's VisualMagic 
development staff transferred to Empresa. At December 31, 1998, the 
Company held non-voting preferred shares of Empresa.

An executive officer agreed to acquire an investment in
Empresa. Empresa's Amended and Restated Articles of Incorporation 
limit the voting rights of DRC and its executive officers to less 
than 20% of the outstanding voting stock. Accordingly, the Company 
is accounting for this transaction as a cost-based investment.

12. Risks and Uncertainties
In 1998, 62% of the Company's sales were to U.S. Government 
agencies, primarily the DoD. All of DRC's government contracts are 
subject to termination for convenience in accordance with 
government regulations. Costs incurred under cost-reimbursable 
contracts are subject to audit by the government. The results of 
prior audits, completed through 1996 have not had a material effect 
on the Company.

In 1998, 22% of the Company's sales were to agencies of state
governments. The cost-reimbursable and fixed-price contracts the 
Company has won are generally multi-year efforts. In accordance 
with state laws, funding must be approved annually by the states' 
legislatures.

During the second half of 1998 the economic and financial crisis in
Asia adversely impacted Encoder Division sales and profits. 
Management has addressed these issues by reducing certain costs and 
does not anticipate that there will be a material impact on future 
operations.

Management's Responsibility for Financial Statements

The management of Dynamics Research Corporation is responsible for 
the accuracy and internal consistency of all information contained 
in this annual report, including the consolidated financial 
statements. Management has followed those generally accepted 
accounting principles which it believes to be most appropriate to 
the circumstances of the Company, and has made what it believes to 
be reasonable and prudent judgments and estimates where necessary.

Dynamics Research Corporation operates under a system of
internal accounting controls designed to provide reasonable 
assurance that its financial records are accurate, that the assets 
of the Company are protected, and that the financial statements 
present fairly the financial position and results of operations of 
the Company. The internal accounting control system is tested, 
monitored and revised as necessary.

Three directors of the Company, not members of management,
serve as the Audit Committee of the Board of Directors and are the 
principal means through which the Board supervises the performance 
of the financial reporting duties of management. The Audit 
Committee meets with management and the Company's independent 
auditors several times a year to review the results of external 
audits of the Company and to discuss plans for future audits. At 
these meetings the Audit Committee also meets privately with the 
independent auditors to assure its free access to them.

The Company's independent auditors, Arthur Andersen LLP,
audited the financial statements prepared by the management of 
Dynamics Research Corporation. Their report on these statements is 
presented below.

Report of Independent Public Accountants

To Dynamics Research Corporation:

We have audited the accompanying consolidated balance sheets of
Dynamics Research Corporation (a Massachusetts corporation) and 
subsidiaries as of December 31, 1998, 1997 and December 28, 1996, 
and the related consolidated statements of operations, 
shareholders' investment and cash flows for the years then ended. 
These financial statements are the responsibility of the Company's 
management. Our responsibility is to express an opinion on these 
financial statements based on our audits.

We conducted our audits in accordance with generally accepted
auditing standards. Those standards require that we plan and 
perform the audit to obtain reasonable assurance about whether the 
financial statements are free of material misstatement. An audit 
includes examining, on a test basis, evidence supporting the 
amounts and disclosures in the financial statements. An audit also 
includes assessing the accounting principles used and significant 
estimates made by management, as well as evaluating the overall 
financial statement presentation. We believe that our audits 
provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above
present fairly, in all material respects, the financial position of 
Dynamics Research Corporation and subsidiaries as of December 31, 
1998,  1997 and December 28, 1996, and the results of their 
operations and their cash flows for the years then ended in 
conformity with generally accepted accounting principles.

                         DYNAMICS RESEARCH CORPORATION

                           1993 EQUITY INCENTIVE PLAN


1.  PURPOSE

     The purpose of this 1993 Equity Incentive Plan 
(the "Plan") is to advance the interests of Dynamics Research 
Corporation (the "Company") by enhancing its ability to attract and 
retain employees and other persons or entities who are in a position 
to make significant contributions to the success of the Company and 
its subsidiaries through ownership of shares of the Company's common 
stock ("Stock").

     The Plan is intended to accomplish these goals 
by enabling the Company to grant Awards in the form of Options, 
Stock Appreciation Rights, Restricted Stock or Unrestricted Stock 
Awards, Deferred Stock Awards, Performance Awards, Loans or 
Supplemental Grants, or combinations thereof, all as more fully 
described below.

2.  ADMINISTRATION

The Plan will be administered by the Compensation Committee (the "Committee")
of the Board of Directors of the Company (the "Board").  The Committee
will have authority, not inconsistent with the express provisions of the
Plan and in addition to other authority granted under the Plan, to (a) grant
Awards at such time or times as it may choose; (b) determine the 
size of each Award, including the number of shares of Stock subject 
to the Award; (c) determine the type or types of each Award; (d) 
determine the terms and conditions of each Award; (e) waive 
compliance by a Participant (as defined below) with any obligations 
to be performed by the Participant under an Award and waive any term 
or condition of an Award; (f) amend or cancel an existing Award in 
whole or in part (and if an award if canceled, grant another Award 
in its place on such terms as the Committee shall specify), except 
that the Committee may not, without the consent of the holder of an 
Award, take any action under this clause with respect to such Award 
if such action would adversely affect the rights of such holder; (g) 
prescribe the form or forms of instruments that are required or 
deemed appropriate under the Plan, including any written notices and 
elections required of Participants, and change such forms from time 
to time; (h) adopt, amend and rescind rules and regulations for the 
administration of the Plan; and (i) interpret the Plan and decide 
any questions and settle all controversies and disputes that may 
arise in connection with the Plan.  Such determinations and actions 
of the Committee, and all other determinations and actions of the 
Committee made or taken under authority granted by any provision of 
the Plan, will be conclusive and will bind all parties.  Nothing in 
this paragraph shall be construed as limiting the power of the 
Committee or the Board to make adjustments under Section 7.3 or 
Section 8.6.

3.  EFFECTIVE DATE AND TERM OF PLAN

     The Plan will become effective on the date on which it is approved
by the stockholders of the Company.  Grants of Awards under the plan may
be made prior to that date (but after Board adoption of the Plan),
subject to such approval of the Plan.

     No Award may be granted under the Plan after April 27, 2003, but Awards
previously granted may extend beyond that date.

4.   SHARES SUBJECT TO THE PLAN

     Subject to adjustment as provided in Section 8.6 below, the aggregate
number of shares of Stock that may be delivered under the Plan will be
1,000,000.  If any Award requiring exercise by the Participant for delivery
of Stock terminates without having been exercised in full, or if any Award
payable in Stock or cash is satisfied in cash rather than Stock, the
number of shares of Stock as to which such Award was not exercised or for
which cash was substituted will be available for future grants.

     Stock delivered under the Plan may be either authorized but unissued
Stock or previously issued Stock acquired by the Company and held in
treasury.  No fractional shares of Stock will be delivered under the Plan.

5.  ELIGIBILITY AND PARTICIPATION

     Those eligible to receive Awards under the Plan ("Participants")
will be persons in the employ of the Company or any of its subsidiaries
("Employees") and other persons or entities (including without limitation
non-Employee directors of the Company or a subsidiary of the Company)
who, in the opinion of the Committee, are in a position to make a
significant contribution to the success of the Company or its subsidiaries.
A "subsidiary" for purposes of the Plan will be a corporation in which the
Company owns, directly or indirectly, stock possessing 50% or more of the
total combined voting power of all classes of stock.  

6.  TYPES OF AWARDS

     6.1.  OPTIONS

     (a)  Nature of Options.  An Option is an Award entitling the recipient
on exercise thereof to purchase Stock at a specified exercise price.

     Both "incentive stock options," as defined in Section 422 of the
Internal Revenue Code of 1986, as amended (the "Code") (any Option intended
to qualify as an incentive stock option being hereinafter referred to
as an "ISO"), and Options that are not incentive stock options, may be
granted under the Plan.  ISOs shall be awarded only to Employees.

     (b)  Exercise Price.  The exercise price of an 
Option will be determined by the Committee subject to the following:

          (1)  The exercise price of an ISO shall not be less than 100%
(110% in the case of an ISO granted to a ten-percent shareholder)
of the fair market value of the Stock subject to the Option,
determined as of the time the Option is granted.  A "ten-percent
shareholder" is any person who at the time of grant owns, directly or
indirectly, or is deemed to own by reason of the attribution rules of
section 424(d) of the Code, stock possessing more than 10% of the total
combined voting power of all classes of stock of the Company or of any 
of its subsidiaries.

          (2)  In no case may the exercise price paid for Stock which is
part of an original issue of authorized Stock be less than the par
value per share of the Stock.

          (3)  The Committee may reduce the exercise price of an Option at
any time after the time of grant, but in the case of an Option
originally awarded as an ISO, only with the consent of the Participant.

     (c)  Duration of Options.  The latest date on 
which an Option may be exercised will be the tenth anniversary 
(fifth anniversary, in the case of an ISO granted to a ten-percent 
shareholder) of the day immediately preceding the date the Option 
was granted, or such earlier date as may have been specified by the 
Committee at the time the Option was granted.

     (d)  Exercise of Options.  Options granted under any single Award
will become exercisable at such time or times, and on such conditions,
as the Committee may specify.  The Committee may at any time and from
time to time accelerate the time at which all or any part of the Option
may be exercised.

     Any exercise of an Option must be in writing, signed by the proper
person and delivered or mailed to the Company, accompanied by (1)
any documents required by the Committee and (2) payment in full in
accordance with paragraph (e) below for the number of shares for which
the Option is exercised.

     (e)  Payment for Stock.  Stock purchased on exercise of an Option
must be paid for as follows: (1) in cash or by check (acceptable to the
Company in accordance with guidelines established for this purpose),
bank draft or money order payable to the order of the Company or (2) if so
permitted by the instrument evidencing the Option (or in the case of an
Option which is not an ISO, by the Committee at or after grant of the
Option), (i) through the delivery of shares of Stock which have been
outstanding for at least six months (unless the Committee expressly
approves a shorter period) and which have a fair market value on the
last business day preceding the date of exercise equal to the exercise
price, or (ii) by delivery of a promissory note of the Option holder to
the Company, payable on such terms as are specified by the Committee, or 
(iii) by delivery of an unconditional and irrevocable undertaking by 
a broker to deliver promptly to the Company sufficient funds to pay 
the exercise price, or (iv) by any combination of the permissible 
forms of payment; provided, that if the Stock delivered upon 
exercise of the Option is an original issue of authorized Stock, at 
least so much of the exercise price as represents the par value of 
such Stock must be paid other than by the Option holder's promissory 
note or personal check.

     (f)  Discretionary Payments.  If the market price of shares of Stock
subject to an Option (other than an Option which is in tandem with a Stock
Appreciation Right as described in Section 6.2 below) exceeds the exercise
price of the Option at the time of its exercise, the Committee may cancel
the Option and cause the Company to pay in cash or in shares of Common Stock
(at a price per share equal to the fair market value per share) to the person
exercising the Option an amount equal to the difference between the 
fair market value of the Stock which would have been purchased 
pursuant to the exercise (determined on the date the Option is 
cancelled) and the aggregate exercise price which would have been 
paid.  The Committee may exercise its discretion to take such action 
only if it has received a written request from the person exercising 
the Option, but such a request will not be binding on the Committee.

6.2.  Stock Appreciation Rights.

     (a)  Nature of Stock Appreciation Rights.  A Stock Appreciation Right
is an Award entitling the recipient on exercise of the Right to receive an
amount, in cash or Stock or a combination thereof (such form to be determined
by the Committee), determined in whole or in part by reference to
appreciation in Stock value.

     In general, a Stock Appreciation Right entitles the Participant to
receive, with respect to each share of Stock as to which the Right is
exercised, the excess of the share's fair market value on the date of
exercise over its fair market value on the date the Right was granted.
However, the Committee may provide at the time of grant that the amount
the recipient is entitled to receive will be adjusted upward or downward
under rules established by the Committee to take into account the
performance of the Stock in comparison with the performance of other stocks
or an index or indices of other stocks.  The Committee may also grant Stock
Appreciation Rights that provide, in such limited circumstances 
following a change in control as the Committee may specify (as 
determined by the Committee) the holder of such Right will be 
entitled to receive, with respect to each share of Stock subject to 
the Right, an amount equal to the excess of a specified value (which 
may include an average of values) for a share of Stock during a 
period preceding such change in control over the fair market value 
of a share of Stock on the date the Right was granted.

     (b)  Grant of Stock Appreciation Rights.  Stock Appreciation Rights may
be granted in tandem with, or independently of, Options granted under the
Plan.  A Stock Appreciation Right granted in tandem with an Option which is
not an ISO may be granted either at or after the time the Option is granted.
A Stock Appreciation Right granted in tandem with an ISO may be granted only
at the time the Option is granted.

     (c)  Rules Applicable to Tandem Awards.  When Stock Appreciation Rights
are granted in tandem with Options, the following will apply:

          (1)  The Stock Appreciation Right will be exercisable only at such
time or times, and to the extent, that the related Option is exercisable
and will be exercisable in accordance with the procedure required for
exercise of the related Option.

          (2)  The Stock Appreciation Right will terminate and no longer be
exercisable upon the termination or exercise of the related Option, except
that a Stock Appreciation Right granted with respect to less than the full 
number of shares covered by an Option will not be reduced 
until the number of shares as to which the related Option has 
been exercised or has terminated exceeds the number of shares 
not covered by the Stock Appreciation Right.

          (3)  The Option will terminate and no longer be exercisable
upon the exercise of the related Stock Appreciation Right.

          (4)  The Stock Appreciation Right will be transferable only
with the related Option.

          (5)  A Stock Appreciation Right granted 
in tandem with an ISO may be exercised only when the market 
price of the Stock subject to the Option exceeds the exercise 
price of such option.

     (d)  Exercise of Independent Stock Appreciation 
Rights.  A Stock Appreciation Right not granted in tandem with an 
Option will become exercisable at such time or times, and on such 
conditions, as the Committee may specify.  The Committee may at any 
time accelerate the time at which all or any part of the Right may 
be exercised.

     Any exercise of an independent Stock Appreciation Right must be in
writing, signed by the proper person and delivered or mailed to the
Company, accompanied by any other documents required by the Committee.

     6.3.  Restricted and Unrestricted Stock.

     (a)  Nature of Restricted Stock Award.  A Restricted Stock Award
entitles the recipient to acquire, for a purchase price equal to par value,
shares of Stock subject to the restrictions described in paragraph
(d) below ("Restricted Stock").

     (b)  Acceptance of Award.  A Participant who is 
granted a Restricted Stock Award will have no rights with respect to 
such Award unless the Participant accepts the Award by written 
instrument delivered or mailed to the Company accompanied by payment 
in full of the specified purchase price, if any, of the shares 
covered by the Award.  Payment may be by certified or bank check or 
other instrument acceptable to the Committee.

     (c)  Rights as a Stockholder.  A Participant who receives
Restricted Stock will have all the rights of a stockholder with respect
to the Stock, including voting and dividend rights, subject to the
restrictions described in paragraph (d) below and any other conditions
imposed by the Committee at the time of grant.  Unless the Committee
otherwise determines, certificates evidencing shares of Restricted Stock
will remain in the possession of the Company until such shares are free
of all restrictions under the Plan.

     (d)  Restrictions.  Except as otherwise specifically provided by the
Plan, Restricted Stock may not be sold, assigned, transferred, pledged or
otherwise encumbered or disposed of, and if the Participant ceases to be an
Employee or otherwise suffers a Status Change (as defined at Section 7.2(a)
below) for any reason, must be offered to the Company for purchase for the
amount of cash paid for the Stock, or forfeited to the Company if no cash 
was paid.  These restrictions will lapse at such time or times, and 
on such conditions, as the Committee may specify.  The Committee may 
at any time accelerate the time at which the restrictions on all or 
any part of the shares will lapse.

     (e)  Notice of Election.  Any Participant making an election under
Section 83(b) of the Code with respect to Restricted Stock must provide a
copy thereof to the Company within 10 days of the filing of such election
with the Internal Revenue Service.

     (f)  Other Awards Settled with Restricted Stock.  The Committee may,
at the time any Award described in this Section 6 is granted, provide
that any or all the Stock delivered pursuant to the Award will be Restricted
Stock.

     (g)  Unrestricted Stock.  The Committee may, in 
its sole discretion, approve the sale to any Participant of shares 
of Stock free of restrictions under the Plan for a price which is 
not less than the par value of the Stock.

     6.4.  Deferred Stock.

     A Deferred Stock Award entitles the recipient to receive shares of
Stock to be delivered in the future.  Delivery of the Stock will take
place at such time or times, and on such conditions, as the Committee may
specify.  The Committee may at any time accelerate the time at which
delivery of all or any part of the Stock will take place.  At the time any
Award described in this Section 6 is granted, the Committee may provide that,
at the time Stock would otherwise be delivered pursuant to the Award, the
Participant will instead receive an instrument evidencing the 
Participant's right to future delivery of Deferred Stock.

     6.5.  Performance Awards; Performance Goals.

     (a)  Nature of Performance Awards.  A Performance Award entitles the
recipient to receive, without payment, an amount in cash or Stock or a
combination thereof (such form to be determined by the Committee) following
the attainment of Performance Goals.  Performance Goals may be related to
personal performance, corporate performance, departmental performance or any
other category of performance deemed by the Committee to be 
important to the success of the Company.  The Committee will 
determine the Performance Goals, the period or period during which 
performance is to be measured and all other terms and conditions 
applicable to the Award.

     (b)  Other Awards Subject to Performance Condition.  The Committee
may, at the time any Award described in this Section 6 is granted, impose
the condition (in addition to any conditions specified or authorized in
this Section 6 or any other provision of the Plan) that Performance Goals
be met prior to the Participant's realization of any payment or benefit
under the Award.

     6.6.  Loans and Supplemental Grants.

     (a)  Loans.  The Company may make a loan to a 
Participant ("Loan"), either on the date of or after the grant of 
any Award to the Participant.  A Loan may be made either in 
connection with the purchase of Stock under the Award or with the 
payment of any Federal, state and local income tax with respect to 
income recognized as a result of the Award.  The Committee will have 
full authority to decide whether to make a Loan and to determine the 
amount, terms and conditions of the Loan, including the interest 
rate (which may be zero), whether the Loan is to be secured or 
unsecured or with or without recourse against the borrower, the 
terms on which the Loan is to be repaid and the conditions, if any, 
under which it may be forgiven.  However, no Loan may have a term 
(including extensions) exceeding ten years in duration.

     (b)  Supplemental Grants.  In connection with any Award, the
Committee may at the time such Award is made or at a
later date, provide for and grant a cash award to the Participant 
("Supplemental Grant") not to exceed an amount equal to (1) the 
amount of any federal, state and local income tax on ordinary income 
for which the Participant may be liable with respect to the Award, 
determined by assuming taxation at the highest marginal rate, plus 
(2) an additional amount on a grossed-up basis intended to make the 
Participant whole on an after-tax basis after discharging all the 
Participant's income tax liabilities arising from all payments under 
this Section 6.  Any payments under this subsection (b) will be made 
at the time the Participant incurs Federal income tax liability with 
respect to the Award.

7.  EVENTS AFFECTING OUTSTANDING AWARDS

     7.1.  Death. 

     If a Participant dies, the following will apply:

     (a)  All Options and Stock Appreciation Rights 
held by the Participant immediately prior to death, to the extent 
then exercisable, may be exercised by the Participant's executor or 
administrator or the person or persons to whom the Option or Right 
is transferred by will or the applicable laws of descent and 
distribution, at any time within the one year period ending with the 
first anniversary of the Participant's death (or such shorter or 
longer period as the Committee may determine), and shall thereupon 
terminate.  In no event, however, shall an Option or Stock 
Appreciation Right remain exercisable beyond the latest date on 
which it could have been exercised without regard to this Section 7.  
Except as otherwise determined by the Committee, all Options and 
Stock Appreciation Rights held by a Participant immediately prior to 
death that are not then exercisable shall terminate at death.

     (b)  Except as otherwise determined by the  Committee,
all Restricted Stock held by the Participant must be
transferred to the Company (and, in the event the certificates 
representing such Restricted Stock are held by the Company, such 
Restricted Stock will be so transferred without any further action 
by the Participant) in accordance with Section 6.3 above.

     (c)  Any payment or benefit under a Deferred Stock Award,
Performance Award, or Supplemental Grant to which the Participant
was not irrevocably entitled prior to death will be
forfeited and the Award canceled as of the time of death, unless 
otherwise determined the Committee.  

     7.2.  Termination of Service (Other Than By Death).

     If a Participant who is an Employee ceases to 
be an Employee for any reason other than death, or if there is a 
termination (other than by reason of death) of the consulting, 
service or similar relationship in respect of which a non-Employee 
Participant was granted an Award hereunder (such termination of the 
employment or other relationship being hereinafter referred to as a 
"Status Change"), the following will apply:

     (a)  Except as otherwise determined by the Committee,
all Options and Stock Appreciation Rights held by the
Participant that were not exercisable immediately prior to the 
Status Change shall terminate at the time of the Status Change.  Any 
Options or Rights that were exercisable immediately prior to the 
Status Change will continue to be exercisable for a period of three 
months (or such longer period as the Committee may determine), and 
shall thereupon terminate, unless the Award provides by its terms 
for immediate termination in the event of a Status Change or unless 
the Status Change results from a discharge for cause which in the 
opinion of the Committee casts such discredit on the Participant as 
to justify immediate termination of the Award.  In no event, 
however, shall an Option or Stock Appreciation Right remain 
exercisable beyond the latest date on which it could have been 
exercised without regard to this Section 7.  For purposes of this 
paragraph, in the case of a Participant who is an Employee, a Status 
Change shall not be deemed to have resulted by reason of (i) a sick 
leave or other bona fide leave of absence approved for purposes of 
the Plan by the Committee, so long as the Employee's right to 
reemployment is guaranteed either by statute or by contract, or (ii) 
a transfer of employment between the Company and a subsidiary or 
between subsidiary, or to the employment of a corporation (or a 
parent or subsidiary corporation of such corporation) issuing or 
assuming an option in a transaction to which section 424(a) of the 
Code applies.

     (b)  Except as otherwise determined by the Committee,
all Restricted Stock held by the Participant at the time
of the Status Change must be transferred to the Company (and, in the 
event the certificates representing such Restricted Stock are held 
by the Company, such Restricted Stock will be so transferred without 
any further action by the Participant) in accordance with Section 
6.3 above.

     (c)  Any payment or benefit under a Deferred Stock
Award, Performance Award, or Supplemental Grant to which the
Participant was not irrevocably entitled prior to the Status Change 
will be forfeited and the Award cancelled as of the date of such 
Status Change unless otherwise determined by the Committee.

     7.3.  Certain Corporate Transactions.

     In the event of a consolidation or merger in which
the Company is not the surviving corporation or which results
in the acquisition of substantially all the Company's outstanding 
Stock by a single person or entity or by a group of persons and/or 
entities acting in concert, or in the event of the sale or transfer 
of substantially all the Company's assets or a dissolution or 
liquidation of the Company (a "covered transaction"), all 
outstanding Awards (except as provided below) will terminate as of 
the effective date of the covered transaction; provided, however, 
that:

     (a)  all outstanding Options shall become exercisable
immediately prior to such covered transaction;

     (b)  the Committee may in its sole discretion, prior to
the effective date of such covered transaction, (i) make each
outstanding Stock Appreciation Right exercisable in full, (ii) remove
the restrictions from each outstanding share of Restricted
Stock, (iii) cause the Company to make any payment and provide any benefit
under each outstanding Deferred Stock Award, Performance Award and 
Supplemental Grant which would have been made or provided with 
the passage of time had such covered transaction not occurred 
and the Participant not suffered a Status Change (or died), 
and (iv) forgive all or any portion of the principal of or 
interest on a Loan; and

     (c)  the Committee may arrange, subject to consummation of such covered
transaction, for the assumption of any or all Awards by the surviving
or acquiring corporation or an affiliate thereof or for the grant of 
replacement awards for any or all Awards which, in the 
judgment of the Committee, are substantially equivalent and 
which in the case of incentive options shall satisfy the 
requirements of section 424(a) of the Code.

8.  GENERAL PROVISIONS

     8.1.  Documentation of Awards.

     Awards will be evidenced by such written instruments,
if any, as may be prescribed by the Committee from time to
time.  Such instruments may be in the form of agreements to be
executed by both the Participant and the Company, or certificates, 
letters or similar instruments, which need not be executed by the 
Participant but acceptance of which will evidence agreement to the 
terms thereof.

     8.2.  Rights as a Stockholder, Dividend Equivalents.

     Except as specifically provided by the Plan, the receipt
of an Award will not give a Participant rights as a stockholder;
the participant will obtain such rights, subject to any
limitations imposed by the Plan or the instrument evidencing the 
Award, upon actual receipt of Stock.  However, the Committee may, on 
such conditions as it deems appropriate, provide that a Participant 
will receive a benefit in lieu of cash dividends that would have 
been payable on any or all Stock subject to the Participant's Award 
had such Stock been outstanding.  Without limitation, the Committee 
may provide for payment to the Participant of amounts representing 
such dividends, either currently or in the future, or for the 
investment of such amounts on behalf of the Participant.

     8.3.  Conditions on Delivery of Stock.

     The Company will not be obligated to deliver any shares
of Stock pursuant to the Plan or to remove restriction
from shares previously delivered under the Plan (a) until all 
conditions of the Award have been satisfied or removed, (b) until, 
in the opinion of the Company's counsel, all applicable federal and 
state laws and regulation have been complied with, (c) if the 
outstanding Stock is at the time listed on any stock exchange, until 
the shares to be delivered have been listed or authorized to be 
listed on such exchange upon official notice of notice of issuance, 
and (d) until all other legal matters in connection with the 
issuance and delivery of such shares have been approved by the 
Company's counsel.  If the sale of Stock has not been registered 
under the Securities Act of 1933, as amended, the Company may 
require, as a condition to exercise of the Award, such 
representations or agreements as counsel for the Company may 
consider appropriate to avoid violation of such Act and may require 
that the certificates evidencing such Stock bear an appropriate 
legend restricting transfer.

     If an Award is exercised by the Participant's legal
representative, the Company will be under no obligation to
deliver Stock pursuant to such exercise until the Company is 
satisfied as to the authority of such representative.

     8.4.  Tax Withholding.

     The Company will withhold from any cash payment made
pursuant to an Award an amount sufficient to satisfy all
federal, state and local withholding tax requirements (the 
"withholding requirements").

     In the case of an Award pursuant to which Stock may be
delivered, the Committee will have the right to require that
the Participant or other appropriate person remit to the Company an 
amount sufficient to satisfy the withholding requirements, or make 
other arrangements satisfactory to the Committee with regard to such 
requirements, prior to the delivery of any Stock.  If and to the 
extent that such withholding is required, the Committee may permit 
the Participant or such other person to elect at such time and in 
such manner as the Committee provides to have the Company hold back 
from the shares to be delivered, or to deliver to the Company, Stock 
having a value calculated to satisfy the withholding requirement.

     If at the time an ISO is exercised the Committee
determines that the Company could be liable for withholding
requirements with respect to a disposition of the Stock received
upon exercise, the Committee may require as a condition of
exercise that the person exercising the ISO agree (a) to inform the 
Company promptly of any disposition (within the meaning of section 
424(c) of the Code) of Stock received upon exercise, and (b) to give 
such security as the Committee deems adequate to meet the potential 
liability of the Company for the withholding requirements and to 
augment such security from time to time in any amount reasonably 
deemed necessary by the Committee to preserve the adequacy of such 
security.


     8.5.  Nontransferability of Awards.

     No Award (other than an Award in the form of an outright
transfer of cash or Unrestricted Stock) may be transferred
other than by will or by the laws of descent and distribution, and 
during an employee's lifetime an Award requiring exercise may be 
exercised only by the Participant (or in the event of the 
Participant's incapacity, the person or persons legally appointed to 
act on the Participant's behalf).

     8.6.  Adjustments in the Event of Certain Transactions.

     (a)  In the event of a stock dividend, stock split
or combination of shares, recapitalization or other change in
the Company's capitalization, or other distribution to common 
stockholders other than normal cash dividends, after the effective 
date of the Plan, the Committee will make any appropriate 
adjustments to the maximum number of shares that may be delivered 
under the Plan under Section 4 above.

     (b)  In any event referred to in paragraph (a), the
Committee will also make any appropriate adjustments to the
number and kind of shares of stock or securities subject to Awards 
then outstanding or subsequently granted, any exercise prices 
relating to Awards and any other provision of Awards affected by 
such change.  The Committee may also make such adjustments to take 
into account material changes in law or in accounting practices or 
principles, mergers, consolidations, acquisitions, dispositions or 
similar corporate transactions, or any other event, if it is 
determined by the Committee that adjustments are appropriate to 
avoid distortion in the operation of the Plan.

     8.7.  Employment Rights, Etc.

     Neither the adoption of the Plan nor the grant of Awards
will confer upon any person any right to continued retention
by the Company or any subsidiary as an Employee or
otherwise, or affect in any way the right of the Company or 
subsidiary to terminate an employment, service or similar 
relationship at any time.  Except as specifically provided by the 
Committee in any particular case, the loss of existing or potential 
profit in Awards granted under the Plan will not constitute an 
element of damages in the event of termination of an employment, 
service or similar relationship even if the termination is in 
violation of an obligation of the Company to the Participant.
 
     8.8.  Deferral of Payments.

     The Committee may agree at any time, upon request of the Participant,
to defer the date on which any payment under an Award will be made.

     8.9. Past Services as Consideration.

     Where a Participant purchases Stock under an Award
for a price equal to the par value of the Stock the Committee
may determine that such price has been satisfied by past services 
rendered by the Participant.


9.  EFFECT, DISCONTINUANCE, CANCELLATION, AMENDMENT AND TERMINATION
 
     Neither adoption of the Plan nor the grant of Awards
to a Participant will affect the Company's right to grant to
such Participant awards that are not subject to the Plan, to issue 
to such Participant Stock as a bonus or otherwise, or to adopt other 
plans or arrangements under which Stock be issued to Employees.

     The Board may at any time or times amend the Plan
or any outstanding Award for any purpose which may at the time
be permitted by law, or may at any time terminate the Plan as to any 
further grants of Awards, provided that (except to the extent 
expressly required or permitted by the Plan) no such amendment will, 
without the approval of the stockholders of the Company, effectuate 
a change for which stockholder approval is required in order for the 
Plan to continue to qualify for the award of ISOs under section 422 
of the Code and to continue to qualify under Rule 16b-3 promulgated 
under Section 16 of the 1934 Act.




Amended as of
February 17, 1998


                        DYNAMICS RESEARCH CORPORATION

              1995 STOCK OPTION PLAN FOR NON-EMPLOYEE DIRECTORS


     1.   PURPOSE

     The purpose of this 1995 Stock Option Plan for
Non-Employee Directors (the "Plan") is to advance the interests
of Dynamics Research Corporation (the "Company") by enhancing the 
ability of the Company to attract and retain non-employee directors 
who are in a position to make significant contributions to the 
success of the Company and to align the interest of those directors 
more closely with the stockholders.


     2.  ADMINISTRATION

     The Plan shall be administered by a committee (the
"Committee") of the Board of Directors (the "Board") of the
Company designated by the Board for that purpose.  Unless and
until a Committee is appointed the Plan shall be administered by the 
entire Board, and references in the Plan to the "Committee" shall be 
deemed references to the Board.  The Committee shall have authority, 
not inconsistent with the express provisions of the Plan, (a) to 
grant options in accordance with the Plan to such directors as are 
eligible to receive options; (b) to prescribe the form or forms of 
instruments evidencing options and any other instruments required 
under the Plan and to change such forms from time to time; (c) to 
adopt, amend and rescind rules and regulations for the 
administration of the Plan; (d) to accelerate the vesting of or 
otherwise change the terms of any option granted hereunder; and 
(e) to interpret the Plan and to decide any questions and settle all 
controversies and disputes that may arise in connection with the 
Plan.  Such determinations of the Committee shall be conclusive and 
shall bind all parties.


     3.  EFFECTIVE DATE AND TERM OF PLAN

     The Plan shall become effective on the date on which
the Plan is approved by the Board of Directors of the Company,
subject to approval by the shareholders of the Company.  No
option shall be granted under the Plan after the completion of ten 
years from the date on which the Plan was adopted by the Board, but 
options previously granted may extend beyond that date.


     4.  SHARES SUBJECT TO THE PLAN

     (a)  Number of Shares.  Subject to adjustment as provided
in Section 4(c), the aggregate number of shares of
the Company's common stock (the "Stock") that may be
delivered upon the exercise of options granted under the Plan shall 
be 100,000.  If any option granted under the Plan terminates without 
having been exercised in full, the number of shares of Stock as to 
which such option was not exercised shall be available for future 
grants within the limits set forth in this Section 4(a).

     (b)  Shares to be Delivered.  Shares delivered under
the Plan shall be authorized but unissued Stock or, if the
Board so decides in its sole discretion, previously issued
Stock acquired by the Company and held in treasury.  No fractional 
shares of Stock shall be delivered under the Plan.
  
     (c)  Changes in Stock.  In the event of a stock dividend, stock
split or combination of shares, recapitalization or other change in
the Company's capital stock, after the effective date of the Plan, the
number and kind of shares of stock or securities of the Company subject to
options then outstanding or subsequently granted under the Plan, the
maximum number of shares or securities that may be delivered under the Plan,
the exercise price, and other relevant provisions shall be 
appropriately adjusted by the Committee, whose determination shall 
be binding on all persons.


     5.  ELIGIBILITY FOR OPTIONS

     Directors eligible to receive options under the Plan
("Eligible Directors") shall be those directors who are not
employees of the Company or of any subsidiary of the Company.


     6.  TERMS AND CONDITIONS OF OPTIONS

     (a)  Number of Options.  

     On the date of the first annual meeting of stockholders
following the adoption of this Plan each Eligible Director
who is elected, reelected or continuing as a director on
such date shall be awarded on such date an option covering 5,000 
shares of Stock; thereafter, at each annual meeting or meeting of 
the board of directors at which a new Eligible Director is elected 
to the Board or following the election by the Board of a new 
Eligible Director to the Board, he or she shall be awarded an option 
covering 5,000 shares of Stock; and at each annual meeting 
subsequent to the annual meeting at which the initial grant was made 
to an Eligible Director and at which he or she is reelected or is 
continuing as a director, he or she shall be awarded an additional 
option covering 1,000 shares of Stock.

     (b)  Exercise Price.  The exercise price of each
option shall be 100% of the fair market value per share of the
Stock on the date the option is granted.  In no event, however, 
shall the option price be less, in the case of an original issue of 
authorized stock, than par value per share.  For purposes of this 
paragraph, (A) the fair market value of a share of Stock on any date 
shall be the Closing Price on such day or, if there was no Closing 
Price on such day, the latest day prior thereto on which there was a 
Closing Price; and (B) the "Closing Price" of the Stock on any 
business day will be the last sale price as reported on the 
principal market on which the Stock is traded or, if no last sale is 
reported, then the mean between the highest bid and lowest asked 
prices on that day. 

     (c)  Duration of Options.  The latest date on which
an option may be exercised (the "Final Exercise Date")
shall be the date which is ten years from the date the option was 
granted.

     (d)  Exercise of Options.

     (1)  Each option shall become exercisable to the extent of
one-third of the shares covered thereby on the date of the Annual 
Meeting held in each of the first, second and third 
years following the date of grant, except that options 
granted on dates other than the date of the Annual 
Meeting shall become exercisable to the extent of one-
third of the shares covered thereby on each of the 
first, second and third anniversaries of the date of the 
grant.

     (2)  Any exercise of an option shall be in writing, signed by
the proper person and delivered or mailed to the Company, 
accompanied by (i) any documentation required by the 
Committee and (ii) payment in full for the number of 
shares for which the option is exercised.

     (3)  The Committee shall have the right to require
that the individual exercising the option remit
to the Company an amount sufficient to satisfy any
federal, state, or local withholding tax requirements 
(or make other arrangements satisfactory to the employer 
with regard to such taxes) prior to the delivery of any 
Stock pursuant to the exercise of the option.  If 
permitted by the Committee the individual exercising the 
option may elect, at such time and in such manner as the 
Committee may prescribe, to have the Company hold back 
from the transfer Stock having a value calculated to 
satisfy such withholding obligation.  In the case of an 
individual subject to Section 16(b) of the Exchange Act, 
no such election shall be effective unless made in 
compliance with the applicable requirements of Rule 16b-
3 or any successor Rule under the Securities Exchange 
Act of 1934, as amended (the "Exchange Act").

     (4)  If an option is exercised by the executor
or administrator of a deceased director, or by
the person or persons to whom the option has been 
transferred by the director's will or the applicable 
laws of descent and distribution, the Company shall be 
under no obligation to deliver Stock pursuant to such 
exercise until the Company is satisfied as to the 
authority of the person or persons exercising the 
option.

     (e)  Payment for and Delivery of Stock.  Stock
purchased under the Plan shall be paid for as follows:  (i) in
cash or by check (acceptable to the Company in accordance with 
guidelines established for this purpose), bank draft or money order 
payable to the order of the Company; (ii) through the delivery of 
shares of Stock (which, in the case of shares of Stock acquired from 
the Company, have been outstanding for at least six months) having a 
fair market value on the last business day preceding the date of 
exercise equal to the purchase price; (iii) by having the Company 
hold back from the shares transferred upon exercise Stock having a 
fair market value on the last business day preceding the date of 
exercise equal to the exercise price; (iv) by delivery of an 
unconditional and irrevocable undertaking by a broker to deliver 
promptly to the Company sufficient funds to pay the purchase price; 
or (v) by any combination of the permissible forms of payment; 
provided, that if the Stock delivered upon exercise of the option is 
an original issue of authorized Stock, at least so much of the 
exercise price as represents the par value of such Stock shall be 
paid other than with a personal check or promissory note of the 
option holder.

     An option holder shall not have the rights of a
shareholder with regard to awards under the Plan except as to
Stock actually received by him or her under the Plan.

     The Company shall not be obligated to deliver
any shares of Stock (a) until, in the opinion of the
Company's counsel, all applicable federal and state laws and 
regulations have been complied with, and (b) if the outstanding 
Stock is at the time listed on any stock exchange, until the shares 
to be delivered have been listed or authorized to be listed on such 
exchange upon official notice of issuance, and (c) until all other 
legal matters in connection with the issuance and delivery of such 
shares have been approved by the Company's counsel.  If the sale of 
Stock has not been registered under the Securities Act of 1933, as 
amended, the Company may require, as a condition to exercise of the 
option, such representations or agreements as counsel for the 
Company may consider appropriate to avoid violation of such Act and 
may require that the certificates evidencing such Stock bear an 
appropriate legend restricting transfer.

     (f)  Nontransferability of Options.  No option
may be transferred other than by will or by the laws of
descent and distribution, and during a director's lifetime an option 
may be exercised only by him or her.

     (g)  Death.  Upon the death of any Eligible Director
granted options under this Plan, all options not then
exercisable shall terminate.  All options held by the director that 
are exercisable immediately prior to death may be exercised by his 
or her executor or administrator, or by the person or persons to 
whom the option is transferred by will or the applicable laws of 
descent and distribution, at any time within one year after the 
director's death (subject, however, to the limitations of Sec-
tion 6(c) regarding the maximum exercise period for such option).  
After completion of that one-year period, such options shall 
terminate to the extent not previously exercised.

     (h)  Other Termination of Status of Director.
If a director's service with the Company terminates for
any reason other than death, all options held by the director that 
are not then exercisable shall terminate.  Options that are 
exercisable on the date of termination shall continue to be 
exercisable for a period of three months (subject to Section 6(c)).  
After completion of that three-month period, such options shall 
terminate to the extent not previously exercised, expired or 
terminated.

     (i)  Mergers, etc.  In the event of a consolidation
or merger in which the Company is not the surviving
corporation or which results in the acquisition of substantially all 
the Company's outstanding Stock by a single person or entity or by a 
group of persons and/or entities acting in concert, or in the event 
of a sale or transfer of substantially all of the Company's assets 
or a dissolution or liquidation of the Company, all options 
hereunder will terminate; provided, that immediately prior to any 
such merger, consolidation sale, dissolution, or liquidation, all 
options outstanding hereunder that are not otherwise exercisable 
shall become exercisable; and provided, further that in the event 
such a transaction is to be accounted for as a pooling of interests, 
the Company shall provide for the surviving or acquiring corporation 
or an affiliate thereof to assume such options or to grant each 
holder of an option hereunder outstanding at the time of the 
transaction replacement options on substantially equivalent terms, 
in each case without a requirement that such director continue to 
serve as a director of the surviving or acquiring corporation or an 
affiliate thereof.


     7.  EFFECT, DISCONTINUANCE, CANCELLATION, AMENDMENT,
         TERMINATION AND EFFECTIVENESS

     Neither adoption of the Plan nor the grant of options
to a director shall affect the Company's right to grant
to such director options that are not subject to the Plan, to issue 
to such directors Stock as a bonus or otherwise, or to adopt other 
plans or arrangements under which Stock may be issued to directors.

     The Committee may at any time terminate the Plan
as to any further grants of options.  The Committee may at any
time or times amend the Plan for any purpose which may at the time 
be permitted by law.

       (a)    Commitments.  The Borrowers wish to establish a revolving
credit facility with the Lenders in an aggregate principal amount at any
one time outstanding not in excess of $40,000,000 (as such amount may be
reduced from time to time pursuant to 2.3) (the "Total Commitment").
Each Lender is severally willing to establish such revolving credit
facility on behalf of the Borrowers, subject to the terms and conditions
hereafter set forth, in the aggregate maximum amounts at any one time
outstanding set forth opposite each Lender's name and in the respective
percentages set forth opposite each Lender's name which shall be applicable
to such revolving credit facility hereunder (hereinafter referred to as such
Lender's "Percentage"):

       Lender                     Commitment              Percentage
                                                     of Total Commitment

BBH&Co                            $10,668,000               26.67%

Chase                              $8,000,000               20.00%

State Street                       $8,000,000               20.00%

Citizens                           $5,332,000               13.33%


TOTAL                             $40,000,000              100.00%


        (b)     Revolving Loans.  Subject to the terms and conditions set
forth in this Credit Agreement, each Lender hereby severally establishes a
revolving credit facility in favor of the Borrowers in the individual
principal amount of such Lender's Percentage of the Total Commitment.  Each
Lender agrees to lend to any Borrower, and any Borrower may borrow, repay,
and reborrow from time to time between the Closing Date and the Maturity
Date, upon notice by any Borrower to the Agent given in accordance with
2.7, such sums as are requested by such Borrower up to a maximum aggregate
principal amount outstanding (after giving effect to all amounts requested)
at any one time equal to such Lender's Percentage of the Available Total
Commitment; provided, however, that the proceeds of any and all borrowings
and reborrowings hereunder shall be used solely for the purposes described
in 5.16.  All Revolving Credit Loans shall be made as LIBOR Loans or Base
Rate Loans, at a Borrower's option.  Base Rate Loans may be converted to
LIBOR Loans; and LIBOR Loans may be continued or converted to Base Rate
Loans under the circumstances, and subject to the conditions, specified in
2.8.  Each request for a Revolving Credit Loan hereunder shall constitute
a representation and warranty by each of the Borrowers that the conditions
set forth in 10 and 11, in the case of the initial Revolving Credit Loans
to be made on the Closing Date, and 11, in the case of all other Revolving
Credit Loans, have been satisfied on the date of such request.

       (c)     Swing Line Loans.

       (i)     On any date prior to the Maturity Date on which the Agent
receives any Loan Request in respect of the Available Total Commitment
pursuant to 2.7, designated as a Swing Line Loan, the Agent promptly shall
notify the Swing Line Lender and, subject to the terms and conditions
hereof, the Swing Line Lender shall, on the date the Agent receives such
Loan Request, make an advance (each a "Swing Line Loan") in accordance
with any such notice.  The aggregate amount of Swing Line Loans at any time
outstanding shall not exceed the lesser of (A) $3,000,000 and (B) the
Available Total Commitment  ("Swing Line Availability").  Until the
Maturity Date, any Borrower may from time to time borrow, repay and reborrow
under this 2.1(c). Each Swing Line Loan shall be made pursuant to a Loan
Request in respect of the Available Total Commitment pursuant to 2.7.  Each
such Loan Request must be given no later than 12:00 p.m. (Boston time) on
the Business Day of the proposed Swing Line Loan.  Notwithstanding any other
provision of this Agreement or the other Loan Documents, the Swing Line
Loans shall constitute Base Rate Loans.  The Borrowers shall repay the
aggregate outstanding principal amount of each Swing Line Loan upon demand
therefor by the Agent, provided that (i) absent an Event of Default or any
other event which, with the giving of notice or passage of time or both,
would constitute an Event of Default, the Agent shall not make such demand
prior to the Business Day next succeeding the date on which such Swing Line
Loan is made and (ii) all amounts of principal and accrued interest
outstanding on the Maturity Date or the earlier maturity by acceleration or
otherwise shall be paid in full on such date.


       (ii)     The Swing Line Lender, at any time and from time to time in
its sole and absolute discretion, may on behalf of each Borrower (and each
Borrower hereby irrevocably authorizes the Swing Line Lender to so act on
its behalf) request each Lender (including the Swing Line Lender in its
capacity as a Lender) to make a Revolving Credit Loan to such Borrower
(which shall be a Base Rate Loan) in an amount equal to such Lender's
Percentage of the aggregate principal amount of the Swing Line Loans made to
such Borrower (the "Refunded Swing Line Loan") outstanding on the date such
notice is given.  Unless any of the events described in 9.1(f) or 9.1(g)
shall have occurred (in which event the procedures of 2.1(c)(iii) shall
apply) and regardless of whether the conditions precedent set forth in
this Credit Agreement to the making of a Revolving Credit Loan are then
satisfied, each Lender shall disburse directly to the Agent such Lender's
Percentage of the Refunded Swing Line Loan on behalf of the Swing Line
Lender, prior to 1:00 p.m. (Boston time), in immediately available funds on
the Business Day next succeeding the date such notice is given.  The
proceeds of such Revolving Credit Loans shall be immediately paid to the
Swing Line Lender and applied to repay the Refunded Swing Line Loan.

       (iii)     If, prior to refunding any Swing Line Loan pursuant to
2.1(c)(ii), one of the events described in 9.1(f) or 9.1(g) shall have
occurred, then, subject to the provisions of 2.1(c)(iv) below, each
Lender will, on the date such Revolving Credit Loan was to have been made
for the benefit of a Borrower, purchase from the Swing Line Lender an
undivided participation interest in the Swing Line Loan in an amount equal
to its Percentage of such Swing Line Loan.  Upon request, each Lender will
promptly transfer to the Swing Line Lender, in immediately available funds,
the amount of its participation and upon receipt thereof the Swing Line
Lender will deliver to such Lender a Swing Line Loan Participation
Certificate, substantially in the form of Exhibit A attached hereto, dated
the date of receipt of such funds and in such amount.

       (iv)     Each Lender's obligation to make Revolving Credit Loans and
topurchase participating interests in accordance with this 2.1(c) shall be
absolute and unconditional and shall not be affected by any circumstance,
including (A) any setoff, counterclaim, recoupment, defense or other right
which such Lender may have against the Swing Line Lender, the Agent, any
Borrower or any other Person for any reason whatsoever, (B) the occurrence
or continuance of any Event of Default or any event which, with the giving
of notice or passage of time or both would constitute an Event of Default,
(C) any inability of a Borrower to satisfy the conditions precedent to
borrowing set forth in this Credit Agreement on the date upon which such
participating interest is to be purchased or (D) any other circumstance,
happening or event whatsoever, whether or not similar to any of the
foregoing.  If any Lender does not make available to the Agent or the
Swing Line Lender, as applicable, the amount required pursuant to 2.1(c)
(ii) or 2.1(c)(iii), as the case may be, the Swing Line Lender shall be
entitled to recover such amount on demand from such Lender, together with
interest thereon for each day from the date of non-payment until such amount
is paid in full at a rate equal to the Base Rate plus the Base Rate Margin.

       2.2.  Fees.

       (a)     Commitment Fee.  The Borrowers agree to pay to the Agent for
the ratable account of each Lender, on each date that DRC delivers to the
Agent a Debt Coverage Certificate pursuant to 2.6(a) and on the Maturity
Date, a commitment fee (the "Commitment Fee") calculated at a rate per annum
of 0.375% on the daily average unused portion of such Lender's portion of
the Available Total Commitment during the immediately preceding fiscal
quarter of DRC (adjusted as appropriate for any reduction or termination of
any portion of the Total Commitment pursuant to 2.3 during the immediately
preceding fiscal quarter or portion thereof).  The Commitment Fee shall be
computed on the basis of the actual number of days elapsed in a year of
360 days and shall be payable in arrears.


       (b)     Agent's Fees.  The Borrowers agree to pay to the Agent, for
the Agent's own account, such other fees as DRC and the Agent have
heretofore agreed upon in writing.

       (c)     Amendment Fee.  The Borrowers agree to pay to the Agent, for
the pro rata benefit of the Lenders, an amendment fee in the amount of
$100,000.

       2.3.  Reduction of Commitments.  Subject to the terms and conditions
of 3, each Borrower shall have the right at any time and from time to time
upon three (3) Business Days' prior written notice to the  Agent (which
shall in turn give prompt written notice to each Lender) to reduce by
$1,000,000 or a multiple of $1,000,000 in excess thereof or terminate
entirely any portion of the Total Commitment, pro rata in accordance with
each Lender's Percentage, whereupon the Total Commitment shall be reduced
accordingly or, as the case may be, terminated.  Upon the effective date of
any such reduction or termination, the Borrowers shall pay to the Agent for
the ratable account of each Lender the full amount of any Commitment Fee
payable pursuant to 2.2(a) then accrued on the amount of the reduction.
No reduction of the Total Commitment may be reinstated.

       2.4.  Revolving Credit Note.  The Revolving Credit Loans made by the
Lenders hereunder shall be evidenced by a single promissory note of the
Borrowers in substantially the form of Exhibit B-1 attached hereto (the
"Revolving Credit Note"), dated as of the Closing Date and completed with
appropriate insertions.  The Revolving Credit Note shall be payable to the
order of the Agent for the ratable account of each Lender in principal
amounts equal to the Total Commitment, or, if less, the aggregate
outstanding amount of all Revolving Credit Loans made by the Lenders
hereunder, plus interest accrued thereon, as set forth below.  The Borrowers
irrevocably authorize the Agent to make or cause to be made, at or about the
time of the Drawdown Date of any Revolving Credit Loan or at the time of
receipt of any payment of principal or interest on the Revolving Credit
Note, an appropriate notation on its Record reflecting the making of such
Revolving Credit Loan or (as the case may be) the receipt of such payment
and the respective pro-rata allocations to each Lender in accordance with
its respective Percentage of the Total Commitment.  The Agent shall record
the outstanding amount of the Revolving Credit Loans on the Record as prima
facie evidence of the principal amount thereof owing and unpaid to the Agent
for the ratable account of the  Lenders, but the failure to record, or any
error in so recording, any such amount on the Record shall not limit or
otherwise affect the obligations of the Borrowers hereunder or under the
Revolving Credit Note to make payments of principal of or interest on the
Revolving Credit Note when due.  The Revolving Credit Note shall be due and
payable on the Maturity Date, provided that the Maturity Date may, with the
approval of all of the Lenders, be extended annually thereafter for each of
the next two twelve-month periods following the Maturity Date.

       2.5.  Swing Line Note.  The Swing Line Loans shall be evidenced by
a single promissory note in the form attached hereto as Exhibit B-2
(the "Swing Line Note"), payable to the order of the Agent for the account
of the Swing Line Lender, dated as of the Closing Date and in the aggregate
principal amount of $3,000,000 or, if less, the aggregate outstanding amount
of all Swing Line Loans.

       2.6.  Interest on Loans.  

       (a)     DRC shall deliver to the Agent on the Closing Date and on or
before the 45th day immediately following the end of each fiscal quarter of
DRC a certificate duly signed by the chief financial officer or treasurer of
DRC and reasonably satisfactory in form and substance to the Lenders
(a "Debt Coverage Certificate") setting forth the ratio of (i) the
Consolidated Senior Debt of DRC and its Subsidiaries for the immediately
preceding fiscal quarter-end to (ii) Consolidated EBITDA and its
Subsidiaries for the four (4) consecutive quarters ending on such fiscal
quarter-end (the "Debt Coverage Ratio").  Loans shall bear interest at a
rate per annum equal to the Adjusted LIBOR or Base Rate, as the case may
be, plus the applicable margin set forth below based on the Debt Coverage
Ratio (which margin is referred to, in the case of Base Rate Loans, as the
"Base Rate Margin" and, in the case of LIBOR Loans, as the "LIBOR Margin").
Subject to subparagraph (b) below, each change in the applicable margin
based on a change in the Debt Coverage Ratio shall be effective, with
respect to all Loans outstanding on or after the date of delivery of a Debt
Coverage Certificate, from and including the date of delivery of such
certificate until the date immediately preceding the next date of delivery
of a Debt Coverage Certificate indicating another such change.


       Debt Coverage Ratio        Base Rate Margin         LIBOR Margin

              < 1.5                     0.0%                   2.00%

          > 1.5 to < 2.0                0.0%                   2.25%

          > 2.0 to < 2.5               0.25%                   2.50%

              > 2.5                    0.50%                   3.00%

; provided, however; that if the Net Income set forth on the Consolidated
income statement delivered pursuant to clause (ii) of Section 6.2(a) for
the fiscal year ending December 31, 1999 is equal to or more than eighty
percent (80%) of the Net Income set forth on the Projections for such
fiscal year delivered by the Borrowers to the Lenders on November 2, 1998,
pursuant to Section 6.2(e), then from and after April 1, 2000, the foregoing
LIBOR Margin based on the Debt Coverage Ratio shall be replaced in its
entirety by the following:

       Debt Coverage Ratio                 LIBOR Margin

              < 1.5                           1.50%

          > 1.5 to < 2.0                      1.75%

          > 2.0 to < 2.5                      2.00%

              > 2.5                           2.50%



       (b)     During any period when an Event of Default shall have
occurred and be continuing or in the event that DRC fails to provide the
Agent with the Debt Coverage Certificate for any fiscal quarter of DRC, then
until such Event of Default is cured or waived or such certificate is
provided, as the case may be, the applicable margin over the Base Rate shall
be one-half percent (0.50%) and the applicable margin over the Adjusted
LIBOR shall be three  percent (3.00%).

       (c)     Interest on each Base Rate Loan and LIBOR Loan shall be
computed on the basis of the actual number of days elapsed in a year of 360
days, in each case without duplication of any day in successive Interest
Periods.

       (d)     The Borrowers agree to pay to the Agent, for the pro rata
benefit of the Lenders, interest on each Loan in arrears on each Interest
Payment Date with respect thereto.

       2.7.  Requests for Loans.  A Borrower shall give to the Agent written
notice in the form of Exhibit C hereto (or telephonic notice confirmed in a
writing in the form of Exhibit C hereto) of the Loans requested from the
Lenders hereunder (a "Loan Request"), no later than 12:00 noon, Boston
time, (i) no less than one (1) Business Day prior to the proposed Drawdown
Date of any Base Rate Loan and (ii) no less than three (3) LIBOR Business
Days prior to the proposed Drawdown Date of any LIBOR Loans; provided,
however, that a Borrower may give to the Agent a Loan Request for a Swing
Line Loan at any time prior to 12:00 noon, Boston time on the proposed
Drawdown Date of such Swing Line Loan.  Each such notice shall specify (i)
the aggregate principal amount of the Loans requested from the Lenders
specifying whether such Loans are Revolving Credit Loans or Swing Line
Loans (and in any event not in excess of the unused portion of the
Available Total Commitment), (ii) whether such Loans are to be LIBOR Loans
or Base Rate Loans, (iii) the proposed Drawdown Date of such Loans, (iv) in
the case of LIBOR Loans, the Interest Period for such Loans, (v) the purpose
or purposes to which the proceeds of such Loans shall be applied, and (vi)
such other matters as are set forth on Exhibit C.  Each Loan Request shall
be in a minimum aggregate amount of $1,000,000 or a higher integral multiple
of $500,000; provided, however, that each Loan Request for a Swing Line Loan
shall be in a minimum aggregate amount of $100,000 or a higher integral
multiple of $50,000.  The Agent shall then promptly notify each Lender by
written notice of its respective Percentage of the Loans requested.

       2.8.  Conversion and Continuation.

       Each Borrower shall have the right at any time upon prior irrevocable
notice to the Agent (a) not later than 12:00 noon, Boston time, one (1)
Business Day prior to the date of conversion, to convert any LIBOR Loan into
a Base Rate Loan, (b) not later than 12:00 noon, Boston time, three (3)
LIBOR Business Days prior to conversion or continuation, to convert any Base
Rate Loan into a LIBOR Loan or to continue any LIBOR Loan as a LIBOR Loan
for an additional Interest Period, and (c) not later than 12:00 noon, Boston
time, three (3) Business Days prior to conversion, to convert the Interest
Period with respect to any LIBOR Loan to another permissible Interest
Period, subject in each case to the following:

       (i)      each conversion or continuation shall be made pro rata among
the Lenders in accordance with the respective principal amounts of the Loans
comprising the converted or continued Loans;

       (ii)      if less than all the outstanding principal amount of any
Loans shall be converted or continued, then the resulting Loans shall
satisfy the limitations specified in the penultimate sentence of 2.7
regarding the principal amount of Loans;

       (iii)      each conversion shall be effected by the Agent by
recording for the account of each Lender the new Loan of such Lender
resulting from such conversion and reducing the Loan (or portion thereof)
of such Lender being converted by an equivalent principal amount;

       (iv)      accrued interest on a LIBOR Loan (or portion thereof) being
converted or continued shall be paid by the Borrowers at the time of
conversion or continuation;

       (v)      LIBOR Loans may only be converted at a time that is the end
of the Interest Period applicable thereto;

       (vi)      any portion of a Loan maturing or required to be repaid in
less than one month may not be converted into or continued as a LIBOR Loan;

       (vii)      any portion of a LIBOR Loan that cannot be converted into
or continued as a LIBOR Loan by reason of the immediately preceding clause
shall be automatically converted at the end of the Interest Period in effect
for such Loan into a Base Rate Loan; and

       (viii)     no Event of Default and no event which, with the giving of
notice or passage of time or both, would constitute an Event of Default has
occurred and is continuing; provided, however, that the condition set forth
in this clause (viii) shall not be applicable to the conversion of any LIBOR
Loan into a Base Rate Loan pursuant to 2.8(a).


       Each notice pursuant to this 2.8 shall be irrevocable and shall
refer to this Agreement and specify (i) the identity and amount of the Loan
that a Borrower requests be converted or continued, (ii) whether such Loan
is to be converted to or continued as a LIBOR Loan or a Base Rate Loan,
(iii) if such notice requests a conversion, the date of such conversion
(which shall be a LIBOR Business Day) and (iv) if such Loan is to be
converted to or continued as a LIBOR Loan, the Interest Period with respect
thereto.  If no Interest Period is specified in any such notice with respect
to any conversion to or continuation as a LIBOR Loan, the Borrower shall be
deemed to have selected an Interest Period of one month's duration.  The
Agent shall promptly advise the other Lenders of any notice given pursuant
to this 2.8 and of each Lender's portion of any converted or continued
Loans.  If the Borrower shall not have given notice in accordance with this
2.8 to continue any LIBOR Loans into a subsequent Interest Period (and shall
not otherwise have given notice in accordance with this 2.8 to convert such
LIBOR Loans), such LIBOR Loans shall, at the end of the Interest Period
applicable thereto (unless repaid pursuant to the terms hereof),
automatically be converted into Base Rate Loans.

       2.9.  Funds for Loans.  Subject to the satisfaction of the other
conditions set forth herein, to the extent applicable (including 2.7), each
Lender will make available to the Agent on the proposed date of any Loan
(other than a Swing Line Loan) by wire transfer of immediately available
funds not later than 1:00 P.M., Boston time, the aggregate amount of its
Percentage of such Loans requested by the Borrowers, and the Agent shall
credit the aggregate amount so received to the respective  accounts
designated by the Borrowers or, if a Borrower does not designate any
account, to DRC's regular deposit account with the Agent.

       3.  PREPAYMENT OF THE LOANS; RESERVES.

       3.1.  Voluntary Prepayments.  Each Borrower shall have the right, at
its election, to prepay the outstanding amount of any Loans, as a whole or
in part, at any time without penalty or premium, except as provided in
4.8.  A Borrower shall give irrevocable written notice to the Agent, no
later than 12:00 noon, Boston time, one Business Day prior to any proposed
prepayment of Base Rate Loans pursuant to this 3 and no later than 11:00
a.m., Boston time, three LIBOR Business Days prior to any proposed
prepayment of LIBOR Rate Loans pursuant to this 3, in each case specifying
the proposed date of prepayment of the Loans and the principal amount and
accrued interest to be prepaid, and the Agent shall promptly give notice
thereof to each Lender.  Each such prepayment of the Base Rate Loans shall
be in a minimum amount of the lesser of (i) $1,000,000 and (ii) the
aggregate amount outstanding under the Notes being prepaid, and shall be
accompanied by the payment of accrued interest on the principal prepaid to
the date of such prepayment.

       3.2.  Mandatory Prepayments.  If at any time the outstanding
principal amount of all Loans exceeds (or, in the case of any notice of
reduction of the Total Commitment pursuant to 2.3, would exceed) the Total
Commitment, the Borrowers will immediately prepay the applicable Note or
Notes, subject to 4.8, in an amount necessary to cause the outstanding
principal amount of all Loans not to exceed the Total Commitment.

       4.  CERTAIN GENERAL PROVISIONS.

       4.1.  Funds for Payments.

       (a)     All payments of principal, interest, fees and any other
amounts due hereunder or under any of the other Loan Documents shall be made
to the Agent for the ratable account of the Lenders at 40 Water Street,
Boston, Massachusetts 02109, or at such other location as the Agent may from
time to time designate, in each case in Dollars constituting immediately
available funds.


       (b)     All payments by the Borrowers hereunder and under any of the
other Loan Documents shall be made without setoff or counterclaim and free
and clear of and without deduction for any taxes, levies, imposts, duties,
charges, fees, deductions, withholdings, compulsory loans, restrictions or
conditions of any nature now imposed or levied by any jurisdiction or any
political subdivision thereof or taxing or other authority therein unless a
Borrower is compelled by law to make such deduction or withholding or if the
taxes are based upon or measured by the income or profits of the Lenders,
including profits or receipts with respect to the Loans.  If any such
obligation is imposed upon a Borrower with respect to any amount payable by
it hereunder or under any of the other Loan Documents, the Borrowers will
pay to the Agent for the ratable account of the Lenders on the date on which
such amount is due and payable hereunder or under such other Loan Document,
such additional amount in Dollars as shall be necessary
to enable the Lenders to receive the same net amount which the Lenders would
have received on such due date had no such obligation been imposed upon such
Borrower.  The Borrowers will deliver promptly to the Agent certificates or
other valid vouchers for all taxes or other charges deducted from or paid
with respect to payments made by the Borrowers hereunder or under such other
Loan Document.  In the event any Lender receives a refund of any taxes or
other amounts for which it has received payment from a Borrower pursuant to
this 4.1(b), such Lender shall, within 30 days from the date of such
receipt, pay the amount of such refund to such Borrower but only to the
extent of payments made by such Borrower pursuant to this 4.1(b) and net of
all costs and expenses of the Agent and such Lender relating thereto and
without interest (other than interest, if any, paid by the relevant
government authority with respect to such refund); provided, however, that
the Borrowers upon request of the Agent or any Lender, agree to repay the
amount paid to a Borrower to the Agent or such Lender if the Agent or such
Lender is required to repay such refund to such governmental authority.

       4.2.  Computations.  All computations of interest on the LIBOR Loans
and the Base Rate Loans and of commitment or other fees shall be based on a
360-day year and paid for the actual number of days elapsed.  Except as
otherwise provided in the definition of the term "Interest Period" with
respect to LIBOR Loans, whenever a payment hereunder or under any of the
other Loan Documents becomes due on a day that is not a Business Day, the
due date for such payment shall be extended to the next succeeding Business
Day, and interest shall accrue during such extension.

       4.3.  Inability to Determine Adjusted LIBOR.  In the event, prior to
the commencement of any Interest Period relating to any LIBOR Loan, the
Agent shall determine that adequate and reasonable methods do not exist
in the marketplace for ascertaining the Adjusted LIBOR that would otherwise
determine the rate of interest to be applicable to any LIBOR Loan during any
Interest Period, the Agent shall give notice of such determination (which
shall be conclusive and binding on the Borrowers) to the Borrowers.  In such
event (a) any Loan Request with respect to LIBOR Loans shall be
automatically withdrawn and shall be deemed a request for Base Rate Loans,
(b) each LIBOR Loan will automatically, on the last day of the then current
Interest Period thereof, become a Base Rate Loan, and (c) the obligations of
the Lenders to make LIBOR Loans shall be suspended until the Agent
determines that the circumstances giving rise to such suspension no
longer exist, whereupon the Agent shall so notify the Borrowers.

       4.4.  Illegality.  Notwithstanding any other provisions herein, if
any present or future law, regulation, treaty or directive or change in the
interpretation or application thereof shall make it unlawful for any Lender
to make or maintain LIBOR Loans, such Lender shall forthwith give notice of
such circumstances to the Agent who shall in turn notify the Borrowers and
thereupon (a) the commitment of such Lender to make LIBOR Loans shall
forthwith be suspended and (b) the Loans then outstanding as LIBOR Loans
from such Lender, if any, shall be converted automatically to Base Rate
Loans on the last day of each Interest Period applicable to such LIBOR
Loans or within such earlier period as may be required by law.  The
Borrowers hereby agree promptly to pay the Agent on behalf of such Lender,
upon demand by such Lender accompanied by a certificate setting forth in
reasonable detail such costs, any additional amounts necessary to compensate
such Lender for any costs incurred by such Lender in making any conversion
in accordance with this 4.4, including any interest or fees payable by such
Lender to lenders of funds obtained by it in order to make or maintain its
LIBOR Loans hereunder; provided, that to the extent permitted by applicable
law, each Lender shall maintain each LIBOR Loan until the last day of an
Interest Period.

       4.5.  Additional Costs, Etc.  If any change in any present
applicable law or if any future applicable law, which expression, as used
herein, includes statutes, rules and regulations thereunder and
interpretations thereof by any competent court or by any governmental or
other regulatory body with the administration or the interpretation thereof
and directives, instructions and notices at any time or from time to time
hereafter made upon or otherwise issued to any Lender by any central bank or
other fiscal, monetary or other authority (whether or not having the force
of law, but only if it is mandatory that such Lender comply), shall:

       (a)     subject such Lender to any tax, levy, impost, duty, charge,
fee, deduction or withholding of any nature with respect to this Credit
Agreement, the other Loan Documents, or the Loans (other than taxes based
upon or measured by the income or profits of such Lender, including without
limitation profits or receipts with respect to the Loans and other than any
withholding tax imposed on any payments by the Borrowers to such Lender);
or

       (b)     materially change the basis of taxation (except for changes
in taxes on income or profits and except for any withholding tax imposed on
any payments by the Borrowers to the Lenders) of payments to such Lender of
the principal of or the interest on any Loans or any other amounts payable
to such Lender under this Credit Agreement or the other Loan Documents; or

       (c)     impose or increase or render applicable (other than to the
extent specifically provided for elsewhere in this Credit Agreement) any
special deposit, reserve, assessment, liquidity, capital adequacy or other
similar requirements (whether or not having the force of law, but only if it
is mandatory that such Lender comply) against assets held by, or deposits in
or for the account of, or loans by, or commitments of an office of such
Lender; or


       (d)     impose on such Lender any other conditions or requirements
with respect to this Credit Agreement, the other Loan Documents, the Loans,
or any class of loans or commitments of which any of the Loans forms a part;

and the result of any of the foregoing is to:

       (i)  increase the cost to such Lender of making, funding, issuing or
maintaining any of the Loans or its Percentage of the Total Commitment; or

       (ii)  reduce the amount of principal, interest or other amount
payable to such Lender hereunder on account of any of the Loans or its
Percentage of the Total Commitment; or

       (iii)  require such Lender to make any payment or to forego any
interest or other sum payable hereunder, the amount of which payment or
foregone interest or other sum is calculated by reference to the gross
amount of any sum receivable or deemed received by such Lender from the
Borrower hereunder;

then, and in each such case, the Borrower will, within ten (10) Business
Days following receipt of written notice from the Agent on behalf of such
Lender, which written notice shall include a description of the relevant
change in law, calculations of the amounts payable, pay to the Agent on
behalf of such Lender such additional amounts as will be sufficient to
compensate such Lender for such additional cost, reduction, payment or
foregone interest or other sum.


       4.6.  Capital Adequacy.  If any change in any present law,
governmental rule, regulation, policy, guideline or directive or if any
future law, governmental rule, regulation, policy, guideline or directive
(in each case whether or not having the force of law, but only if it is
mandatory that the Lender comply) or the interpretation thereof by a court
or governmental authority with appropriate jurisdiction or any change in any
such law or interpretation (including, without limitation, any change
according to a prescribed schedule of increasing requirements, whether or
not known on the date of this Credit Agreement) affects the amount of
capital required or expected to be maintained by any Lender or any
corporation controlling such Lender and such Lender determines that the
amount of capital required to be maintained by it is increased by or based
upon the existence of the Commitments or Loans made pursuant hereto, then
the Agent on behalf of such Lender may notify the Borrower of such fact.
To the extent the costs of such increased capital requirements are not
reflected in the applicable rate(s) of interest on the Loans, the Borrower
and the Agent on behalf of such Lender shall thereafter attempt to negotiate
in good faith, within thirty (30) days of the day on which the Borrower
receives such notice, an adjustment payable hereunder that will adequately
compensate such Lender in light of these circumstances.  If the Borrower and
the Agent on behalf of such Lender are unable to agree to such adjustment
within thirty (30) days of the date on which the Borrower receives such
notice, then commencing on the date Borrower received such notice (but not
earlier than the effective date of any such increased capital requirement),
from time to time the Borrower will pay to the Agent, on behalf of such
Lender after consultation with the affected Lender, such additional amount
that will, in the Agent's reasonable determination, provide adequate
compensation to such Lender.  Such Lender shall allocate such cost increases
among its customers in good faith and on an equitable basis.

       4.7.  Certificate.  A certificate setting forth any additional
amounts payable pursuant to 4.5, 4.6 or 4.8 and a reasonably detailed
explanation of such amounts which are due, including calculation of such
amounts, submitted by the Agent on behalf of any Lender to the Borrowers,
shall be conclusive, absent manifest error, that such amounts are due and
owing.

       4.8.  Indemnity.  The Borrowers agree to indemnify each Lender and
to hold each Lender harmless from and against any loss, cost or expense that
such Lender may sustain or incur resulting from (a) a default by a Borrower
in payment of the principal amount of or any interest on any Loans as and
when due and payable, including any such loss or expense arising from
interest or fees payable by such Lender to lenders of funds obtained by it
in order to maintain its Loans, (b) a default by a Borrower in making a
borrowing after such Borrower has given (or is deemed to have given) a Loan
Request relating thereto in accordance with 2.7 or (c) the making of any
payment or prepayment of a Loan or the conversion of any LIBOR Loan to a
Base Rate Loan on a day that is not the last day of the applicable Interest
Period with respect thereto, including interest or fees payable by such
Lender to lenders of funds obtained by it in order to maintain any such
Loans.

       4.9.  Interest on Overdue Amounts.  Overdue principal and (to the
extent permitted by applicable law) interest on the Loans and all other
overdue amounts payable hereunder or under any of the other Loan Documents
shall bear interest payable on demand at a rate per annum equal to (i) in
the case of overdue principal and interest (to the extent permitted by law)
of any Loan, 2% plus the rate otherwise applicable to such Loan as provided
in 2.6 or (ii) in the case of any other amount, 2% plus the then prevailing
Base Rate plus the then prevailing applicable margin, in each case until
such amount shall be paid in full (after as well as before judgment).

       4.10.     Mitigation.  Each Lender shall take commercially
reasonable efforts (which shall not require such Lender to incur an
unreimbursed loss or unreimbursed cost or expense or otherwise take any
action inconsistent with its internal policies or suffer any disadvantage or
burden deemed by it to be significant) to assign its rights and delegate and
transfer its obligations hereunder to another of its offices to the extent
that such assignment, delegation and transfer would reduce amounts otherwise
payable by the Borrowers to such Lender pursuant to 4.1(b), 4.4, 4.5, 4.6
and 4.8 or to make or maintain LIBOR Loans hereunder.  The Borrowers agree
to pay all costs and expenses incurred by any Lender in connection with any
such assignment, delegation and transfer.


       4.11.     Joint and Several Obligations.  Notwithstanding any other
provision of this Credit Agreement, (i) each of the covenants, agreements
and obligations of any Borrower set forth in this Credit Agreement or in
any other Loan Document shall be the joint and several covenants, agreements
and obligations of all of the Borrowers, regardless of whether a Borrower
was the actual recipient of the proceeds of a Loan, (ii) all representations
and warranties of any Borrower contained in this Credit Agreement or in any
other Loan Document shall be deemed to be separately made by each of the
Borrowers and (iii) any notice, request, consent, report or other
information or agreement delivered by any Borrower shall be deemed for all
purposes to be consented to, ratified and delivered by each of the
Borrowers.  In furtherance of the foregoing, each Borrower acknowledges and
agrees that each covenant, agreement and obligation of any or all of the
Borrowers in this Credit Agreement or any other Loan Document is
enforceable against all Borrowers, jointly, or against any Borrower,
severally.

       5.  REPRESENTATIONS AND WARRANTIES.  In order to induce the Lenders
to enter into this Credit Agreement and to make the Loans provided for
hereunder, each Borrower makes the following representations and warranties,
which shall survive the execution and delivery hereof and of the Notes:

       5.1       Organization, Standing, etc. of the Borrowers.  Each
Borrower is a corporation duly organized, validly existing and in good
standing under the laws of The Commonwealth of Massachusetts and has all
requisite corporate power and authority to own and operate its properties,
to carry on its business as now conducted and proposed to be conducted, to
enter into this Agreement, the other Loan Documents and all other documents
to be executed by it in connection with the transactions contemplated
hereby, to issue the Notes and to carry out the terms hereof and thereof.
Each of this Agreement and the other Loan Documents is the legal, valid and
binding obligation of each Borrower enforceable against such Borrower in
accordance with its terms.

       5.2       Subsidiaries.  Schedule 5.2 attached hereto correctly sets
forth as to each Subsidiary, its name, the jurisdiction of its
incorporation, the number of shares of its capital stock of each class
outstanding and the number of such outstanding shares owned by DRC and its
other Subsidiaries.  Each such Subsidiary is a corporation duly organized,
validly existing and in good standing under the laws of the jurisdiction of
its incorporation and has all requisite corporate power and authority to own
and operate its properties and to carry on its business as now conducted and
proposed to be conducted.  All of the outstanding capital stock of each
Subsidiary is validly issued, fully-paid and nonassessable, and is owned by
DRC or its Subsidiaries as specified in Schedule 5.2, in each case free of
any mortgage, pledge, lien, security interest, charge, option or other
encumbrance, other than restrictions imposed by applicable federal and state
securities laws.

       5.3       Qualification.  Each Borrower and its Subsidiaries are
duly qualified or licensed and in good standing as foreign corporations
duly authorized to do business in each jurisdiction in which the character
of the properties owned or the nature of the activities conducted makes such
qualification or licensing necessary.


       5.4       Financial Information; Disclosure, etc.  The Borrowers have
furnished the Lenders with the financial statements and other reports listed
in Schedule 5.4 attached hereto.  Such financial statements have been
prepared in accordance with GAAP applied on a consistent basis and fairly
present the financial position and results of operations of the Persons to
which they purport to relate as of the dates and for the periods indicated.
Since the end of the most recent fiscal period shown in such financial
statements or in the most recent financial statements delivered by DRC under
6.2(a), there has not been any material adverse change in the business,
operations, condition (financial or otherwise) or properties of Borrowers
and their Subsidiaries, taken as a whole.  Neither this Agreement nor any
financial statements, reports, projections or other documents or certificates
furnished to the Lenders by the Borrowers in connection with the transactions
contemplated hereby contain as of their respective dates any untrue
statement of a material fact or omit to state any material
fact necessary to make the statements herein or therein contained not
misleading.  None of the Loans will render any Borrower unable to pay its
debts as they become due; no Borrower is contemplating either the filing of
a petition by it under any state or federal bankruptcy or insolvency laws
or, except as set forth on Schedule 5.4, the liquidation of all or a major
portion of its property; and no Borrower has knowledge of any Person
contemplating the filing of any such petition against it.

       5.5       Licenses, etc.  Schedule 5.5 attached hereto accurately and
completely lists all authorizations, licenses, permits and franchises of any
public or governmental regulatory body which are necessary for the conduct
of the business of each Borrower and its Subsidiaries as now conducted and
the absence of which would result, either in any case or in the aggregate,
in a material adverse change in the business, operations, affairs, condition
(financial or otherwise) or properties of (i) DRC and its Subsidiaries,
taken as a whole, (ii) Encoder and its Subsidiaries, taken as a whole, or
(iii) Metrigraphics and its Subsidiaries, taken as a whole (such
authorizations, licenses, permits and franchises, together with any
extensions or renewals thereof, being herein sometimes referred to
collectively as the "Licenses").  All of such Licenses are in full force and
effect and each Borrower and its Subsidiaries have fulfilled and performed
all of their obligations with respect thereto and have full power and
authority to operate thereunder. 

       5.6       Material Agreements.  Schedule 5.6 attached hereto
accurately and completely lists all material agreements and contracts which
are presently in effect in connection with the conduct of the business of
any Borrower and which were or are required to be filed with the Securities
and Exchange Commission as a "material contract" pursuant to Item 601(b)(10)
of Registration S-K promulgated by the Securities and Exchange Commission.

       5.7       Tax Returns and Payments.  Each Borrower and its
Subsidiaries have filed all tax returns required by law to be filed and have
paid all material taxes, assessments and other governmental charges levied
upon any of their respective properties, assets, income or franchises, other
than those not yet delinquent and those, not material in aggregate amount,
being or about to be contested as provided in 6.7.  The charges, accruals
and reserves on the books of each Borrower and its Subsidiaries in respect
of their respective taxes are adequate in the opinion of the Borrowers, and
the Borrowers know of no unpaid assessment for additional taxes or of any
basis therefor.


       5.8       Indebtedness, Liens and Investments, etc.  Schedule 5.8
attached hereto sets forth, as of the date hereof, (a) the amounts of all
outstanding Indebtedness of each Borrower and its Subsidiaries in respect
of borrowed money, Capitalized Leases and the deferred purchase price of
property, (b) all existing mortgages, liens and security interests in
respect of such Indebtedness, (c) all agreements which directly or
indirectly require any Borrower or its Subsidiaries to make any material
investments, loans or advances and (d) all existing material guarantees by
each Borrower and its Subsidiaries.

       5.9       Title to Properties; Liens.  Each Borrower and its
Subsidiaries have good and marketable title to all of their respective
properties and assets, and none of such properties or assets is subject
to any mortgage, pledge, lien, security interest, charge or encumbrance
except for (i) Permitted Liens and (ii) minor liens and encumbrances which
in the aggregate are not substantial in amount, do not in any case
materially detract from the value of the property subject thereto or
materially impair the operations of any Borrower and its Subsidiaries and
have not arisen otherwise than in the ordinary course of business.  Each
Borrower and its Subsidiaries enjoy quiet possession under all leases to
which they are parties as lessees, and, to the knowledge of each Borrower,
all of such leases are valid, subsisting and in full force and effect.  None
of such leases contains any provision restricting the incurrence of
indebtedness by the lessee.

       5.10      Litigation, etc.  Except as set forth in Schedule 5.10
attached hereto, there is no action, proceeding or investigation pending or
threatened (or any basis therefor known to any Borrower) which questions the
validity of this Credit Agreement, the Notes or the other documents executed
in connection herewith, or any action taken or to be taken pursuant hereto,
or which could reasonably be expected to result, either in any case or in
the aggregate, in any material adverse change in the business, operations,
affairs, condition (financial or otherwise) or properties of DRC and the
Subsidiaries, taken as a whole, or any of their respective properties or
in any material liability on the part of DRC and the Subsidiaries, taken
as a whole.

       5.11      Authorization; Compliance with Other Instruments.  The
execution, delivery and performance of this Agreement and the Notes have
been duly authorized by all necessary corporate action on the part of each
Borrower, will not result in any violation of or be in conflict with or
constitute a default under any term of the charter or by-laws of any
Borrower, or of any agreement, instrument, judgment, decree, order, statute,
rule or governmental regulation applicable to any Borrower, or result in the
creation of any mortgage, lien, charge or encumbrance upon any of the
properties or assets of any Borrower pursuant to any such term.  Neither
any Borrower nor any Subsidiary is in violation of any term of its charter
or by-laws, or of any term of any material agreement or instrument to which
it is a party, or, to each Borrower's knowledge, of any judgment, decree,
order, statute, rule or governmental regulation applicable to it.

       5.12      Governmental Consent.  Except as specified in Schedule
5.12 attached hereto, no order, consent, approval or authorization of, or
declaration to or filing with, any governmental authority (collectively,
"Consents") is required to be obtained or made by any Borrower or by any
Subsidiary in connection with the execution and delivery of this Agreement
and the issuance and delivery of the Notes pursuant hereto.  Except as set
forth in Schedule 5.12, all of the Consents have been obtained and are in
full force and effect.

       5.13      Regulation U, etc.  Neither any Borrower nor any
Subsidiary owns or has any present intention of acquiring any "margin stock"
within the meaning of Regulation U (12 CFR Part 221) of the Board of
Governors of the Federal Reserve System (herein called "margin stock").
None of the proceeds of the Loans will be used, directly or indirectly, by
any Borrower or any Subsidiary for the purpose of purchasing or carrying, or
for the purpose of reducing or retiring any indebtedness which was originally
incurred to purchase or carry, any margin stock or for any other purpose
which might constitute the transactions contemplated hereby a "purpose
credit" within the meaning of said Regulation U, or cause this Agreement
to violate Regulation U, Regulation T, Regulation X, or any other regulation
of the Board of Governors of the Federal Reserve System or the Securities
Exchange Act of 1934.

       5.14       Employee Retirement Income Security Act of 1974.
Each Employee Benefit Plan and, to each Borrower's knowledge, each
Multiemployer Plan, is in material compliance with applicable provisions of
ERISA and the Code.  No ERISA Reportable Event has occurred or, to each
Borrower's knowledge, is imminent or likely to occur.  No Borrower or
ERISA Affiliate has incurred any material liability to the PBGC or any
Employee Benefit Plan or Multiemployer Plan on account of any failure to
meet the contribution requirements of any such plan, minimum funding
requirements or prohibited transactions under ERISA or the Code,
termination of a single employer plan, partial or complete withdrawal from a
Multiemployer Plan, or the insolvency, reorganization or termination of any
Multiemployer Plan, and no event has occurred or conditions exist which
present a material risk that any Borrower or ERISA Affiliate will incur any
material liability on account of any of the foregoing circumstances.  The
consummation of the transactions contemplated by this Agreement will not
result in any prohibited transaction under ERISA or the Code for which an
exemption is not available.


       5.15       Environmental Matters.  Except as set forth in Schedule
5.15 attached hereto, neither any Borrower nor any Subsidiary nor, to each
Borrower's knowledge, any other Person has ever caused or permitted any
Hazardous Material to be disposed of on or under any real property owned,
leased or operated by any Borrower or any Subsidiary or in which any
Borrower or any Subsidiary has ever held, directly or indirectly, any
legal or beneficial interest or estate, and no such real property has ever
been used (either by any Borrower or any Subsidiary or, to each Borrower's
knowledge, by any other Person) as (i) a disposal site or permanent storage
site for any Hazardous Material or (ii) a temporary storage site for any
Hazardous Material.  Each Borrower and each of its Subsidiaries have been
issued and are in compliance with all material permits, certificates,
licenses, approvals and other authorizations relating to environmental
matters and necessary or desirable for their respective businesses, and
have filed all notifications and reports relating to chemical substances,
air emissions, underground storage tanks, effluent discharges and Hazardous
Material waste storage, treatment and disposal required in connection with
the operation of their respective businesses, the failure to have or comply
with which would, individually or in the aggregate, have a material adverse
effect on any Borrower or any Subsidiary.  All Hazardous Materials used or
generated by any Borrower or any Subsidiary or any business merged into or
otherwise acquired by any Borrower or any Subsidiary have been generated,
accumulated, stored, transported, treated, recycled and disposed of in
compliance with all applicable laws and regulations, the violation of which
has any reasonable likelihood of having a material adverse effect on any
Borrower or any Subsidiary.  Neither any Borrower nor any Subsidiary has
any liabilities with respect to Hazardous Materials and no facts or
circumstances exist which could give rise to liabilities with respect to
Hazardous Materials, which in either case, individually or in the aggregate,
could have any reasonable likelihood of having a material adverse effect on
any Borrower or any Subsidiary.

       5.16  Use of Proceeds.  Each Borrower will use the proceeds of the
Loans solely for working capital and other general corporate purposes of the
Borrowers.

       5.17  Investment Company Act; Public Utility Holding Company Act.
Neither any Borrower nor any Subsidiary is (a) an "investment company" as
defined in, or subject to regulation under, the Investment Company Act of
1940 or (b) a "holding company" as defined in, or subject to regulation
under, the Public Utility Holding Company Act of  1935.

       6.    AFFIRMATIVE COVENANTS OF THE BORROWERS.  Each Borrower
covenants and agrees that, so long as any Loan or Note is outstanding or the
Lenders have any Available Total Commitment:

       6.1   Records and Accounts.  Each Borrower will (a) keep true and
accurate records and books of account in which full, true and correct
entries will be made in accordance with GAAP and (b) maintain adequate
accounts and reserves for all taxes (including income taxes), depreciation,
depletion, obsolescence and amortization of its properties, contingencies,
and other reserves, all in accordance with GAAP.

       6.2   Financial Statements, Certificates and Information.  Each
Borrower will furnish or cause to be furnished to each Lender:

       (a)    Within 90 days after the end of each fiscal year of DRC, (i)      
the consolidated and consolidating balance sheets of DRC and its
Subsidiaries as at the end of such year and (ii) the related consolidated

year, setting forth in comparative form with respect to such consolidated
financial statements figures for the previous fiscal year, all in reasonable
detail, together with the opinion thereon of independent public accountants
selected by DRC and satisfactory to the Lenders, which opinion shall be in a
form generally recognized as unqualified and shall state that the financial
statements have been prepared in accordance with generally accepted
accounting principles applied on a basis consistent with that of the
preceding fiscal year (except for changes, if any, which shall be specified
and approved in such opinion) and that the audit by such accountants in
connection with such financial statements has been made in accordance with
generally accepted auditing standards related to reporting; provided,
however, that the Borrowers shall be required to furnish the consolidating
financial statements referred to above only to the extent that the same are
required to be prepared by GAAP or by the Securities and Exchange Commission
or by any other applicable regulatory authority;


       (b)     Within 45 days after the end of each of the first three
quarterly accounting periods in each fiscal year of DRC, (i) the unaudited
consolidated and consolidating balance sheets of DRC and its Subsidiaries
as at the end of such period, and (ii) the related unaudited consolidated
and consolidating statements of income and surplus and cash flows for such
period and for the period from the beginning of the current fiscal year to
the end of such period, all in reasonable detail and signed by the chief
financial officer or treasurer of DRC; provided, however, that the Borrowers
shall be required to furnish the consolidating financial statements only to
the extent that the same are required to be prepared by GAAP or by the
Securities and Exchange Commission or by any other applicable regulatory
authority;

       (c)     Together with the financial statements delivered pursuant to
subparagraph (a) above, a statement signed by the accountants who have
reported on the same to the effect that in connection with their examination
of such financial statements they have reviewed the provisions of this
Agreement and have no knowledge of any event or condition which constitutes
an Event of Default or which, after notice or expiration of any applicable
grace period or both, would constitute such an Event of Default or, if they
have such knowledge, specifying the nature and period of existence thereof;
provided, however, that in issuing such statement, such independent
accountants shall not be required to go beyond normal auditing procedures
conducted in connection with their opinion referred to above;

       (d)     Together with the financial statements delivered pursuant to
subparagraph (a) above, a detailed list of each Borrower's backlog of

       (f)     Together with the financial statements delivered pursuant to
subparagraphs (a) and (b) above, a compliance certificate substantially in
the form of Exhibit D attached hereto signed by the chief financial officer

       (g)     Promptly after the same become publicly available, copies of
all periodic and other reports, proxy statements and other materials filed
by DRC with the Securities and Exchange Commission, or any governmental
authority succeeding to any of or all of the functions of said Commission,
or with any national securities exchange, or distributed to its shareholders
generally, as the case may be (with the exhibits relating thereto to be
provided, at DRC's expense, upon the request of the Agent or any Lender);


       (h)     Promptly upon their becoming available, copies of any
periodic or special reports filed by any Borrower or any Subsidiary with any
federal, state or local governmental agency or authority, if such reports
indicate any material change in the business, operations, affairs or
condition (financial or otherwise) of the Borrowers and the Subsidiaries,
taken as a whole, or if copies thereof are requested by any Lender, and
copies of any materially adverse notices and communications from any
federal, state or local governmental agency or authority which specifically
relate to a Borrower or any Subsidiary;

       (i)     Forthwith upon any officer of any Borrower obtaining
knowledge of any condition or event which constitutes an Event of Default or
which, after notice or lapse of time or both, would constitute an Event of
Default, a certificate signed by such officer specifying in reasonable
detail the nature and period of existence thereof and what action any
Borrower has taken or proposes to take with respect thereto; and

       (j)     Such other information regarding the business, affairs and
condition of the Borrowers and their respective Subsidiaries as such Lender
may from time to time reasonably request.  Each Borrower will permit each
Lender to inspect the books and any of the properties or assets of such
Borrower and its Subsidiaries at such reasonable times as such Lender may
from time to time request.  All costs and expenses of any Lender in
connection with or relating to any request made under this 6.2(j) shall,
if no Event of Default has occurred and is continuing, be paid by the Lender
making such request and, upon the occurrence and during the continuance of
an Event of Default, be paid by the Borrowers.

       6.3    Legal Existence; Compliance with Laws, etc.  Except (a) for
the dissolution of Dynamics Research Investment Corporation, a Massachusetts
corporation and wholly-owned Subsidiary, and (b) as otherwise permitted
under this Credit Agreement, each Borrower will, and will cause each
Subsidiary to: maintain its corporate existence and business; maintain all
properties which are reasonably necessary for the conduct of such business,
now or hereafter owned, in good repair, working order and condition; take
all actions necessary to maintain and keep in full force and effect its
Licenses; in the case of DRC, take all steps necessary to maintain its
status as a public company and to maintain its status as a company listed
on the NASDAQ National Market or a national stock exchange; and, except as
otherwise provided herein, comply with all applicable statutes, rules,
regulations and orders of, and all applicable restrictions imposed by, all
governmental authorities in respect of the conduct of its business 
and the ownership of its properties; in each case except to the extent that
the failure to comply would not, individually or in the aggregate, have a
material adverse effect on the business, operations, affairs or condition
(financial or otherwise) of the Borrowers and their Subsidiaries, taken as
a whole; or any Subsidiary; provided that neither any Borrower nor any
Subsidiary shall be required by reason of this 6.3 to comply therewith at
any time while such Borrower or such Subsidiary shall be contesting its
obligations to do so in good faith by appropriate proceedings promptly
initiated and diligently conducted, and if it shall have set aside on its
books such reserves, if any, with respect thereto as are required by GAAP
and deemed adequate by such Borrower and its independent public accountants.
Neither any Borrower nor any Subsidiary will, without the prior written
consent of the Lenders, engage in any business other than the Current Lines
of Business.


       6.4      Insurance.  Each Borrower will maintain or cause to be
maintained on all insurable properties now or hereafter owned by such
Borrower or any Subsidiary insurance against loss or damage by fire or other
casualty to the extent customary with respect to like properties of
companies conducting similar businesses and will maintain or cause to be
maintained public liability and workmen's compensation insurance insuring
such Borrower and its Subsidiaries to the extent customary with respect to
companies conducting similar businesses and, upon request, will furnish to
the Lenders satisfactory evidence of the same.

       6.5      Payment of Taxes.  Each Borrower will, and will cause each
Subsidiary to, pay and discharge promptly as they become due and payable
all taxes, assessments and other governmental charges or levies imposed
upon it or its income or upon any of its properties or assets, or upon
any part thereof, as well as all lawful claims of any kind (including
claims for labor, materials and supplies) which, if unpaid, might by law
become a lien or a charge upon its property; provided that neither any
Borrower nor any Subsidiary shall be required to pay any such tax,
assessment, charge, levy or claim if the amount, applicability or validity
thereof shall currently be contested in good faith by appropriate
proceedings promptly initiated and diligently conducted and if such Borrower
or such Subsidiary, as the case may be, shall have set aside on its books
such reserves, if any, with respect thereto as are required by GAAP and
deemed appropriate by such Borrower and its independent public accountants.

       6.6      Payment of Other Indebtedness, etc.  Except as to matters
being contested in good faith and by appropriate proceedings, each Borrower
will, and will cause each Subsidiary to, pay promptly when due, or in
conformance with customary trade terms, all other Indebtedness and
obligations incident to the conduct of its business.

       6.7      Further Assurances.  From time to time hereafter, each
Borrower will execute and deliver, or will cause to be executed and
delivered, such additional instruments, certificates or documents, and will
take all such actions, as the Lenders may reasonably request, for the
purposes of implementing or effectuating the provisions of this Agreement or
the other Loan Documents.  Upon the exercise by the Lenders (or the Agent on
their behalf) of any power, right, privilege or remedy pursuant to this
Agreement or the other Loan Documents which requires any consent, approval,
registration, qualification or authorization of any governmental authority
or instrumentality, each Borrower will execute and deliver, or will cause
the execution and delivery of, all applications, certifications, instruments
and other documents and papers that the Lenders may be required to obtain
for such governmental consent, approval, registration, qualification or
authorization.

       6.8      Depository Account.  Each Borrower will maintain its
principal operating accounts with one or more of the Lenders (including
BBH&Co).

       6.9      Use of Proceeds.   Each Borrower will use the proceeds of
the Loans only for the purposes not prohibited by, and subject to the terms
and conditions of, 5.13 and 5.16.


       6.10     No Further Negative Pledges.  Each Borrower hereby
covenants and agrees, at all times while any Loans remain outstanding or
while there is any Available Total Commitment, not to enter into any
agreement prohibiting the creation or assumption of any mortgage, deed of
trust, lien, pledge, hypothecation, encumbrance, charge or security interest
in favor of the Lenders in assets or properties owned by any Borrower,
except for purchase money agreements which contain such provisions, provided
that (i) such provisions relate only to the assets being purchased
thereunder and (ii) such agreements are entered into by any Borrower in the
ordinary course of its business.

       6.11     Regulation U.  If requested by any Lender, each Borrower
will promptly furnish such Lender with a statement in conformity with the
requirements of Federal Reserve Form U-1 referred to in said Regulation U.

Borrower permit any Subsidiary to, directly or indirectly, enter into any
lease or other transaction with any Affiliate of such Borrower or such

Event of Default (other than an event described in 9(f) or 9(g) shall then
be continuing, the Required Lenders may direct the Agent to, by written
notice to any Borrower, (i) declare the principal of and accrued interest
in respect of the Notes to be forthwith due and payable, whereupon the
principal of and accrued interest in respect of the Notes, and all other
amounts then due hereunder, shall become forthwith due and payable without
presentment, demand, protest or other notice of any kind, all of which are
hereby expressly waived by each Borrower, and/or (ii) terminate the Total

then due hereunder, shall automatically become due and payable, without
presentment, demand, protest or any other notice of any kind, all of which
are hereby expressly waived by each of the Borrowers, anything contained
herein or in any other Loan Document to the contrary notwithstanding.

       9.2     Remedies on Default, etc.  In case any one or more Events of
Default shall occur and be continuing, the Lenders may proceed to protect
and enforce their rights by an action at law, suit in equity or other
appropriate proceeding, whether for the specific performance of any
agreement contained herein or in any other Loan Document, or for an
injunction against a violation of any of the terms hereof or thereof, or in
aid of the exercise of any power granted hereby or thereby or by law.  In
case of a default in the payment of any principal of or interest on any
Note, or in the payment of any fee due hereunder, each Borrower will pay
to the Lenders such further amount as shall be sufficient to cover the cost
and expense of collection, including the Lenders' attorneys' fees, expenses
and disbursements.  No course of dealing and no delay on the part of the
Lenders in exercising any right shall operate as a waiver thereof or
otherwise prejudice the Lenders' rights.  No right conferred hereby or by
any other Loan Document upon the Lenders shall be exclusive of any other
right referred to herein or therein or now or hereafter available at law,
in equity, by statute or otherwise.

       10.    CLOSING CONDITIONS.  The obligations of the Lenders to make
the initial Loans shall be subject to the satisfaction of the following
conditions precedent:

to the satisfaction of the following conditions precedent:


       11.1.  Accuracy of Representations; No Event of Default.  After
giving effect to the Loans proposed to be made on such Drawdown Date, (i)
all representations and warranties of each Borrower contained in this Credit
Agreement, the other Loan Documents or in any document or instrument
delivered pursuant to or in connection with this Credit Agreement shall be
true and correct as of the date as of which they were made and shall also be
true and correct at and as of the time of the making of such Loan, with the
same effect as if made at and as of that time (except to the extent of
changes resulting from transactions contemplated or permitted by this Credit
Agreement and the other Loan Documents, or to the extent that such
representations and warranties relate expressly to an earlier date) and (ii)
no Event of Default or other event which, with the giving of notice or
passage of time, would constitute an Event of Default shall have occurred
and be continuing.  On or before the date of the Loans, the Agent, on behalf
of the Lenders, shall have received a certificate of DRC signed by the
chief financial officer or treasurer of DRC to such effect.

       11.2.  No Legal Impediment.  No change shall have occurred in any
law or regulations thereunder or interpretations thereof that in the
reasonable opinion of any Lender would make it illegal for such Lender to
make such Loan.

       12.    THE AGENT.

       12.1.  Appointment, Powers and Immunities.  Each Lender hereby
irrevocably appoints and authorizes the Agent to act as its agent hereunder
and under each of the Loan Documents with such powers as are specifically
delegated to the Agent by the terms of this Credit Agreement and the Loan
Documents, together with such other powers as are reasonably incidental
thereto.  The Agent (which term as used in this sentence and in 12.5 and
the first sentence of 12.6 shall include reference to its Affiliates and
the respective officers, directors, employees and agents of the Agent and
its Affiliates):  (a) shall have no duties or responsibilities except those
expressly set forth in this Credit Agreement to be a trustee for any Lender;
(b) shall not be responsible to the Lenders for any recitals, statements,
representations or warranties contained in this Credit Agreement, or in any
certificate or other document referred to or provided for in, or received by
any of them under, this Credit Agreement, or for the value, validity,
effectiveness, genuineness, enforceability, perfection or sufficiency of
this Credit Agreement, any Note or any other document referred to or
provided for herein or for any failure by any Borrower or any other Person
to perform any of its obligations hereunder or thereunder; (c) shall not be
required to initiate or conduct any litigation or collection proceedings
hereunder except to the extent requested by or consented to by the Required
Lenders; and (d) shall not be responsible for any action taken or omitted to
be taken by it hereunder or under any other document or instrument referred
to or provided for herein or in connection herewith, except for its own
gross negligence or willful misconduct.  The Agent may employ agents and
attorneys-in-fact and shall not be responsible for the negligence or
misconduct of any such agents or attorneys-in-fact selected by it with
reasonable care.  Subject to the foregoing, the Agent shall, on behalf
of the Lenders, exercise any and all rights, powers and remedies of the
Lenders under this Credit Agreement and any other Loan Documents, including
the giving of any consent or waiver or the entering into of any amendment,
subject to the provisions of 25.

       12.2.  Reliance by Agent.  The Agent shall be entitled to rely upon
any certifications, notices or communications (including any communications
by telephone, telex, telegram or cable) believed by it to be genuine and
correct and to have been signed or sent by or on behalf of the proper
Person or Persons, and upon advice and statements of legal counsel,
independent accountants and other experts selected by the Agent.  As to
any matters not expressly provided for by this Credit Agreement, the Agent
shall in all cases be fully protected in acting, or in refraining from
acting, hereunder in accordance with the instructions of the Lenders, and
any action taken or failure to act pursuant thereto shall be binding on all
of the Lenders.


       12.3.  Defaults.  The Agent shall not be deemed to have knowledge of
the occurrence of an Event of Default (other than the nonpayment of
principal of or interest on the Notes) unless the Agent has received written
notice from a Borrower specifying such Event of Default.  In the event that
the Agent receives such a notice of the occurrence of an Event of Default,
the Agent shall give notice thereof to the Lenders (and shall give each
Lender prompt notice of each such nonpayment).  The Agent shall (subject
to the provisions of 24 and 12.7) take such action with respect to such
Event of Default as shall be directed by the Lenders, provided that, unless
and until the Agent shall have received such directions, the Agent may (but
shall not be obligated to) take such action, or refrain from taking such
action, with respect to such Event of Default as it shall deem advisable and
in the best interests of the Required Lenders.

       12.4.  Rights as a Lender.  With respect to its Percentage of the
Total Commitment and the Loans made by it, BBH&Co, in its capacity as a
Lender hereunder shall have the same rights and powers hereunder as any
other Lender and may exercise the same as though it were not acting as the
Agent, and the term "Lender" or "Lenders" shall, unless the context
otherwise indicates, include the Agent in its individual capacity.  The
Agent and its Affiliates may (without having to account therefor to any
Lender) accept deposits from, lend money to and generally engage in any
kind of banking, trust or other business with any Borrower or any of its
Affiliates, as if the Agent were not acting as the agent hereunder, and the
Agent may accept fees and other consideration from any of such Persons for
services as the Agent or otherwise without having to account for the same to
the Lenders.

       12.5.  Indemnification.  The Lenders agree to indemnify the Agent
ratably in accordance with the aggregate principal amount of the Notes held
by the Lenders (or, if no such principal is at the time outstanding,
ratably in accordance with their respective Percentages), for any and all
liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements of any kind and nature whatsoever
which may be imposed on, incurred by or asserted against the Agent in any
way relating to or arising out of this Credit Agreement or referred to
herein or the transactions contemplated by or referred to herein or therein
(including the costs and expenses which any Borrower is obligated to pay
but excluding, unless an Event of Default has occurred and is continuing,
normal administrative costs and expenses incident to the performance of its
agency duties hereunder) or the enforcement of any of the terms of this
Credit Agreement or of any such other documents, provided that no Lender
shall be liable for any of the foregoing to the extent they arise from the
gross negligence or willful misconduct of the Agent.


       12.6.  Non-Reliance on Agent and Other Lenders.  Each Lender agrees
that it has, independently and without reliance on the Agent or any other
Lender, and based on such documents and information as it has deemed
appropriate, made its own credit analysis of the Borrowers and its own
decision to enter into this Credit Agreement and that it will, independently
and without reliance upon the Agent or any other Lender, and based on such
documents and information as it shall deem appropriate at the time, continue
to make its own analysis and decisions in taking or not taking action under
this Credit Agreement.  The Agent shall not be required to keep itself
informed as to the performance or observance by the Borrowers of this Credit
Agreement or any other document referred to or provided for herein or to
inspect the properties or books of the Borrowers.  Except for notices,
reports and other documents and information expressly required to be
furnished to the Lenders by the Agent hereunder, the Agent shall not have
any duty or responsibility to provide any Lender with any credit or other
information concerning the affairs, financial condition or business of the
Borrowers which may come into the possession of the Agent or any of its
Affiliates.  Notwithstanding the foregoing, the Agent will use its best
efforts to provide to the Lenders any and all information reasonably
requested by them and reasonably available to the Agent promptly upon such
request.

       12.7.  Failure to Act.  Except for action expressly required of the
Agent hereunder, the Agent shall in all cases be fully justified in failing
or refusing to act hereunder unless it shall be indemnified to its
satisfaction by the Lenders against any and all liability and expense
which may be incurred by it by reason of taking or continuing to take
any such action.

       12.8.  Resignation of Agent.  Subject to the appointment and
acceptance of a successor  Agent as provided below, the Agent may resign at
any time by giving notice thereof to the Lenders and DRC.  Upon any such
resignation, the Lenders shall appoint a successor Agent which shall be
reasonably satisfactory to DRC.  If no successor Agent shall have been so
appointed by the Lenders and shall have accepted such appointment within 30
days after the retiring Agent's giving of notice of resignation, then the
retiring Agent may, on behalf of the Lenders, appoint a successor Agent
which shall be a Lender which has a combined capital and surplus of at
least $500,000,000 and which shall be reasonably satisfactory to DRC.
Upon the acceptance of any appointment as Agent hereunder by a successor
Agent, such successor Agent shall thereupon succeed to and become vested
with all the rights, powers, privileges and duties of the retiring Agent,
and the retiring Agent shall be discharged from its duties and obligations
hereunder.  After the retiring Agent's resignation hereunder as Agent, the
provisions of this 12 shall continue in effect for its benefit in respect
of any actions taken or omitted to be taken by it while it was acting as the
Agent.

       12.9.  Cooperation of Lenders.  Each Lender shall (a) endeavor to
and shall not be liable for any failure to promptly notify the other Lenders
and the Agent of any Events of Default known to such Lender under this
Credit Agreement and not reasonably believed to have been previously
disclosed to the other Lenders; and (b) provide the other Lenders and
the Agent with such information and documentation as such other Lender or
the Agent shall reasonably request in the performance of their respective
duties hereunder, including all information relative to the outstanding
balance of principal, interest and other sums owed to such Lender.

       12.10.  Amendment of 12.  Each Borrower hereby agrees that the
provisions of this 12 (other than 12.8 and 12.11) generally constitute
an agreement among the Agent and the Lenders and that any and all of the
provisions of this 12 (other than 12.8 and 12.11) may be amended at any
time by the Lenders without the consent or approval of, or notice to, any
Borrower (other than the requirement of notice to DRC of the resignation of
the Agent and other than any provision in addition to 12.8 and 12.11 which
directly affects the Borrowers).


       12.11.  Reliance.  As to any consent that is granted or any other
action that is taken by the Agent hereunder, or under the Loan Documents,
the Borrowers shall be entitled to rely upon any of the foregoing granted,
delivered or taken by the Agent and the Lenders shall be bound thereby,
without the necessity of inquiring or confirming the Agent's authority.

       13.  SETOFF, ETC.  Regardless of the adequacy of any collateral,
during the continuance of any Event of Default, any deposits or other sums
credited by or due from any Lender to any Borrower and any securities or
other property of any Borrower in the possession of any Lender may be
applied to or set off against the pro rata payment of Obligations and
any and all other liabilities, direct, or indirect, absolute or contingent,
due or to become due, now existing or hereafter arising, of the Borrowers
to the Lenders.  The Lenders agree among themselves that, with respect to
all sums received by the Lenders applicable to the payment of principal of
or interest on the Notes, equitable adjustment will be made among the
Lenders so that, in effect, all such sums shall be shared ratably by each
of the Lenders whether received by voluntary payment, by the exercise of the
right of setoff or banker's lien, by counterclaim or crossclaim or by the
enforcement of any or all of the Notes.  If any Lender receives any
payment on its Notes of a sum or sums in excess of its pro rata portion,
then such Lender receiving such excess payment shall purchase for cash from
the other Lenders an interest in their Notes in such amounts as shall
result in a ratable participation by each of the Lenders in the aggregate
unpaid amount of the Notes then outstanding; provided, however, that if all
or any portion of such excess payment is thereafter recovered from such
Lender, the purchase shall be rescinded and the purchase price restored
to the extent of such recovery, but without interest.

       14.  EXPENSES.  Whether or not the transactions contemplated hereby
shall be consummated, each Borrower agrees to pay (a) the reasonable direct,
out-of-pocket costs of reproducing this Credit Agreement, the other Loan
Documents and the other agreements at and instruments mentioned herein,
(b) any taxes (including any interest and penalties in respect thereto)
payable by the Lenders (other than taxes based upon the Lender's net income)
on or with respect to the transactions contemplated by this Credit Agreement
(the Borrowers hereby agreeing to indemnify the Lenders with respect
thereto), (c) the fees, expenses and disbursements of the Agent's counsel
incurred in connection with the preparation of the Loan Documents and other
instruments mentioned herein and the reasonable fees, expenses and
disbursements of the Agent's counsel and any local counsel to the Lenders in
connection with any amendments, modifications, approvals, consents, waivers
or Replacement Lenders hereto or hereunder and (d) all reasonable
out-of-pocket expenses (including attorney fees and costs for external
counsel to the Lenders and the allocated costs and disbursements of
internal counsel of the Lenders) incurred by the Lenders in connection
with (i) the enforcement of or preservation of rights under any of the Loan
Documents against the Borrowers or the administration thereof after the
occurrence of an Event of Default or any event which, with the giving of
notice or passage of time or both, would constitute an Event of Default,
(ii) any replacement of a Lender pursuant to 17.4 and (iii) any litigation,
proceeding or dispute arising hereunder; provided, however, that the
Borrowers shall have no obligation to pay for the expenses of the Agent or
the Lenders to the extent such expenses result from the Agent's or any
Lender's gross negligence, fraud or willful misconduct.

       15.  INDEMNIFICATION.  Each Borrower agrees to indemnify and hold
harmless each Lender from and against any and all claims, actions and suits
whether groundless or otherwise, and from and against any and all
liabilities, losses, damages and expenses of every nature and character
arising out of this Credit Agreement or any of the other Loan Documents
or the transactions contemplated hereby or thereby, including (a) any
actual or proposed use by any Borrower of the proceeds of any of the Loans,
(b) any Borrower entering into or performing this Credit Agreement or any of
the other Loan Documents or (c) with respect to any Borrower and its
properties and assets, the violation of any Environmental Law, the presence,
disposal, escape, seepage, leakage, spillage, discharge, emission, release
or threatened release of any Hazardous Substances or any action, suit,
proceeding or investigation brought or threatened with respect to any
Hazardous Substances (including, but not limited to claims with respect
to wrongful death, personal injury or damage to property), in each case
including the reasonable fees and disbursements of counsel for the Agent,
incurred in connection with any such investigation, litigation or other
proceeding; provided, however, that no Borrower shall have any obligation
to indemnify the Agent or the Lenders for any liabilities, losses, damages
or other expenses (I) incurred in connection with any litigation commenced
by any Borrower against the Agent or any Lender, or by the Agent or any
Lender against any Borrower, which seeks enforcement of any rights hereunder
or under any other Loan Document and is determined adversely to the Agent
or the Lenders in a final nonappealable judgment or (II) to the extent such
liabilities, losses, damages or other expenses result from the Agent's or
any Lender's gross negligence, fraud or willful misconduct.  If, and to the
extent that the obligations of any Borrower under this 15 are unenforceable
for any reason, each Borrower hereby agrees to make the maximum contribution to
the payment in satisfaction of such obligations
which is permissible under applicable law.

       16.  SURVIVAL OF COVENANTS, ETC.  All covenants, agreements,
representations and warranties made herein in any of the other Loan
Documents or in any documents or other papers delivered by or on behalf of
each Borrower pursuant hereto shall be deemed to have been relied upon by
each Lender, notwithstanding any investigation heretofore or hereafter made
by it, and shall survive the making by the Lenders of the Loans, as herein
contemplated, and shall continue in full force and effect so long as any
amount due under this Credit Agreement or any of the other Loan Documents
remains outstanding or the Lenders have any obligation to make any Loans.
All statements contained in any certificate or other paper delivered to the
Lenders at any time by or on behalf of any Borrower pursuant hereto shall
constitute representations and warranties as of the date thereof by the
Borrowers hereunder.

       17.  ASSIGNMENT AND PARTICIPATION.
      
       17.1.  Assignment by the Lenders.  No Lender shall assign or
transfer any of its rights or obligations under any of the Loan Documents
(i) without the prior written consent of DRC, which shall not be
unreasonably withheld or delayed, and (ii) in amounts of less than
$5,000,000 unless such Lender assigns its entire remaining interest
under the Loan Documents; provided, however, that any Lender may, at
any time and from time to time, sell, transfer, assign or otherwise grant an
interest in any Loan to a Subsidiary or any Affiliate of such Lender or to
a Federal Reserve Bank of the United States; and provided, further, that
upon the occurrence and during the continuance of an Event of Default, no
consent of DRC shall be required to any assignment.

       17.2.  Assignment by Borrowers.  No Borrower shall assign or
transfer any of its rights or obligations under any of the Loan Documents
without the prior written consent of the Lenders.

       17.3     Participations by the Lenders.  Any Lender may, without
the consent of any Borrower, the Agent or any other Lender, sell
participations to one or more banks or other entities (each a "Participant")
in all or a portion of such Lender's rights and obligations under this
Credit Agreement (including all or a portion of its Commitment and the
Loans owing to it); provided, however, that (i) such Lender's obligations
under this Credit Agreement shall remain unchanged, (ii) such Lender shall
remain solely responsible to the other parties hereto for the performance
of such obligations, (iii) each Borrower, the Agent, and the other Lenders
shall continue to deal solely and directly with such Lender in connection
with such Lender's rights and obligations under this Credit Agreement and
(iv) such participation shall be in an amount of not less than $5,000,000.
Any agreement or instrument pursuant to which a Lender sells such a
participation shall provide that such Lender shall retain the sole right to
enforce this Credit Agreement and to approve any amendment, modification or
waiver of any provision of this Credit Agreement.  Each Borrower agrees
that each Participant shall be entitled to the benefits of 4.5 to the
same extent as if it were a Lender and had acquired its interest by
assignment pursuant to 17.1.

       17.4  Replacement of Lender.  In the event that any Lender (other
than the Agent in its capacity as a Lender) or, to the extent applicable,
any Participant (the "Affected Lender"):

       (a)     fails to perform its obligations to fund any portion of any
Loan on or after the Closing Date when required to do so by the terms of
this Credit Agreement, or fails to provide its portion of any LIBOR Loan
pursuant to 2 or on account of any legal requirement as contemplated by
4.4;

       (b)     refuses to consent to a proposed extension of the Maturity
Date that is consented to by all of the other Lenders; or

       (c)     refuses to consent to a proposed amendment, modification,
waiver or other action requiring consent of all of the Lenders under 25
that is consented to by Lenders owning at least 75% of the Percentages
of the Total Commitment;


then, so long as no Event of Default exists, DRC shall have the right to
seek, at its own cost and expense, a replacement lender which is reasonably
satisfactory to the Agent and the Required Lenders (the "Replacement
Lender").  The Replacement Lender shall purchase the interests of the
Affected Lender in the Loans and its Commitment and shall assume the
obligations of the Affected Lender hereunder and under the other Loan
Documents upon execution by the Replacement Lender of an assignment
agreement in form and substance reasonably satisfactory to the Replacement
Lender and Affected Lender, and the tender by the Replacement Lender to the
Affected Lender of a purchase price agreed between the Replacement Lender
and the Affected Lender.  Such assignment by any Affected Lender who has
performed its obligations hereunder shall be deemed an early termination
of any Loans to the extent of such Affected Lender's portion thereof, and
the Borrowers will pay to such Affected Lender any resulting amounts due
under 4.8.  Upon consummation of such assignment, (i) the Replacement
Lender shall become party to this Credit Agreement as a signatory hereto and
shall have all the rights and obligations of the Affected Lender under this
Credit Agreement and the other Loan Documents with a Percentage equal to the
Percentage of the Affected Lender, (ii) the Affected Lender shall be
released from its obligations hereunder and under the other Loan Documents
and (iii) no further consent or action by any party shall be required.  The
Borrowers shall sign such documents and take such other actions reasonably
requested by the Replacement Lender to enable it to share in the benefits
of the rights created by the Loan Documents.  Until the consummation of an
assignment in accordance with the foregoing provisions of this 17.4, the
Borrowers shall continue to pay to the Affected Lender any Obligations as
they become due and payable.

       18.  FOREIGN LENDER.  If any Lender is not incorporated or organized
under the laws of the United States of America or a state thereof, such
Lender shall deliver to DRC and the Agent the following:

       (a)     Two duly completed copies of United States Internal Revenue
Service Form 1001 or 4224 or successor form, as the case may be, certifying
in each case that such Lender is entitled to receive payments under this
Credit Agreement and the Notes without deduction or withholding of any
United States federal income taxes; provided, however, that if such Lender
is not a "bank" within the meaning of Section 881(c)(3)(A) of the Code and
cannot deliver Form 1001 or 4224, such Lender shall deliver to DRC and the
Agent a certificate to such effect; and

       (b)     A duly completed Internal Revenue Service Form W-8 or W-9 or
successor form, as the case may be, to establish an exemption from United
States backup withholding tax.

      Each such Lender that delivers to DRC and the Agent a Form 1001 or
4224 and Form W-8 or W-9 pursuant to this 18 further undertakes to deliver
to DRC and the Agent two further copies of Form 1001 or 4224 and Form W-8
or W-9, or successor applicable form, or other manner of certification,
as the case may be, on or before the date that any such form expires or
becomes obsolete or after the occurrence of any event requiring a change
in the most recent form previously delivered by it to DRC and the Agent.
Such Forms 1001 or 4224 shall certify that such Lender is entitled to
receive payments under this Credit Agreement without deduction or
withholding of any United States federal income taxes.  The foregoing
documents need not be delivered in the event any change in treaty, law
or regulation or official interpretation thereof has occurred which
renders all such forms inapplicable or which would prevent such Lender from
delivering any such form with respect to it, or such Lender advises DRC that
it is not capable of receiving payments without any deduction or withholding
of United States federal income tax and, in the case of a Form W-8 or W-9,
establishing an exemption from United States backup withholding tax.  Until
such time as DRC and the Agent have received such forms indicating that
payments hereunder are not subject to United States withholding tax or
are subject to such tax at a rate reduced by an applicable tax treaty,
the Borrowers shall withhold taxes from such payments at the applicable
statutory rate without regard to 4.1(b).

       19.  NOTICES, ETC.  Except as otherwise expressly provided in this
Credit Agreement, all notices and other communications made or required to

In proving this Credit Agreement it shall not be necessary to produce or
account for more than one such counterpart signed by the party against whom
enforcement is sought.

       24.  WAIVER OF JURY TRIAL.  EACH OF THE BORROWERS, THE AGENT AND

right shall operate as a waiver thereof or otherwise be prejudicial thereto.
No notice to or demand upon a Borrower shall entitle a Borrower to other or
further notice or demand in similar or other circumstances.

       27.  SEVERABILITY.  The provisions of this Credit Agreement are
severable and if any one clause or provision hereof shall be held invalid
or unenforceable in whole or in part in any jurisdiction, then such
invalidity or unenforceability shall affect only such clause or provision,

such clause or provision in any other jurisdiction, or any other clause or
provision of this Credit Agreement in any jurisdiction.


       28.  NATURE OF LENDER'S OBLIGATIONS.  The Lenders obligations to
make their respective Loans are several and not joint or joint and several.
Any Lender which is not in default in the performance of its obligations
may, in its discretion, assume the obligations of any other Lender which

Agreement as a sealed instrument as of the date first set forth above.

                        CERTIFICATE OF VOTE OF DIRECTORS
                    ESTABLISHING A CLASS OR SERIES OF STOCK
                    (General Laws, Chapter 156B, Section 26)

     We, Albert Rand, President, and John Wilkinson,
Clerk, of Dynamics Research Corporation located at 60
Frontage Road, Andover, MA 01810-5498 do hereby certify that at a 
meeting of the directors of the corporation held on September 10, 
1998, the following vote establishing and designating a class or 
series of stock and determining the relative rights and preferences 
thereof was duly adopted.  The directors wish to amend the Series B 
Preferred Stock pursuant to Section 26, as no shares of the Series B 
Preferred Stock have been issued at this time.

     VOTED:  That pursuant to the authority vested in the Board of
Directors of this Corporation in accordance with the provisions
of its Restated Articles of Organization, as amended, the voting
powers of the Series B Preferred Stock of the Corporation be and
they hereby are amended as follows:

     Section 3(a) shall be amended to read in its entirety as follows:

     "Each share of Series B Stock shall entitle the holder thereof
     to ten votes on all matters submitted to a vote of the stockholders
     of the Corporation."

     Section 8 shall be amended to read in its entirety as follows:

     "Certain Adjustments.  In the event the Corporation shall
     at any time declare or pay any dividend on Common Stock
     payable in shares of Common Stock, or effect a subdivision
     or combination or consolidation of the outstanding 
     shares of Common Stock (by reclassification or 
     otherwise than by payment of a dividend in shares 
     of Common Stock) into a greater or lesser number 
     of shares of Common Stock, then, in each such 
     case, the amounts set forth in Sections 2(a) and 
     (b), 6(a) and 7 hereof with respect to the 
     multiple of cash and non-cash dividends, the 
     Series B Liquidation Preference and an aggregate 
     amount of stock, securities, cash and/or other 
     property referred to in Section 7 hereof, shall be 
     adjusted by multiplying such amount by a fraction 
     the numerator of which is the number of shares of 
     Common Stock outstanding immediately after such 
     event and the denominator of which is the number 
     of shares of Common Stock that were outstanding 
     immediately prior to such event."

     Signed under the penalties of perjury, this 10th day of
     September, 1998.

                                         Albert Rand, President
