ITEM 1.  BUSINESS

GENERAL

     Forrester Research, Inc. is a leading independent Internet research firm
that conducts research and analysis on the impact of the Internet and emerging
technologies on business strategy, consumer behavior and society. We provide our
clients with a comprehensive and integrated perspective on technology and
business, which we call the Whole View(TM) of Internet commerce. Our Whole View
approach helps companies evolve their business models and infrastructure to
embrace broader on-line markets and to scale their Internet operations. We help
our clients develop e-business strategies that use the Internet and other
emerging technologies to win customers, identify new markets and gain
competitive operational advantages. We target our products and services to large
enterprises, Internet companies and technology vendors. Senior management,
business strategists and marketing and technology professionals use our
prescriptive, actionable research to understand and capitalize on the Internet
and emerging business models and technologies.

     In addition to analyzing the Internet, we also use Internet technologies as
an integral part of our business. We have developed a technology platform that
we call "Forrester eResearch" which allows us to conduct, design, sell and
deliver our research over the Internet in a format specifically developed to
maximize its impact and effectiveness. Our eResearch platform enhances our
research data and content quality and provides our clients with instant access
to our research, on-line tools and presentations and interactive services.

     We offer our clients annual memberships which provide access to our
research on specific business issues and technology topics. These issues and
topics include the impact that the application of the Internet and emerging
technologies may have on business models, operational strategy, financial
results, investment priorities, organizational effectiveness and staffing
requirements. We also provide advisory services to clients that explore in
greater detail the issues and topics covered by our research. We host Forum
events, conferences devoted to critical business and technology issues, which
bring our clients and major technology and business leaders together to discuss
the impact of technology change on business. Additionally, we offer our clients
bit products that consist of research that is collected, analyzed and sold
directly on the Internet.

     The Company was incorporated in Massachusetts on July 7, 1983 and
reincorporated in Delaware on February 21, 1996.

INDUSTRY BACKGROUND

     Internet commerce and emerging technologies continue to rapidly transform
businesses. The rise of both new business models and consumers who are empowered
by the Internet requires companies to adapt their pricing, distribution, sales
channels and supply chains to remain competitive. Decisions about how to develop
e-commerce strategies, how to leverage new media for advertising and marketing
and how to capitalize on
e-business technologies have become increasingly complex, requiring
participation from corporate leaders, line-of-business managers, marketing
executives and technology professionals. Together, these individuals must work
to reduce and even eliminate the traditional separations between marketing,
business strategy and technology to reach new markets, gain competitive
advantage and develop high customer service and loyalty levels. Developing a
comprehensive and coordinated e-business strategy is difficult because as
technology change accelerates, consumers and businesses adopt new methods of
buying and selling and markets grow increasingly dynamic.

     Consequently, demand is growing for external sources of expertise that
provide independent business advice spanning a variety of areas including
Internet commerce, e-business technologies and consumer behavior. We believe
there is a need for objective research which is thematic, prescriptive and
actionable and which provides a comprehensive perspective on the integrated use
of technology in business.

FORRESTER'S SOLUTION

     We believe that our Internet business and technology expertise enables us
to offer our clients the best available research on Internet commerce and
emerging business models and technologies. Our solution provides our clients
with:

          THE WHOLE VIEW OF INTERNET COMMERCE.  We provide our clients with a
     comprehensive and integrated perspective on emerging technologies and
     business, which we call the Whole View of Internet commerce. Our approach
     helps guide our clients in the evolution of their business models and
     infrastructure. We deliver the Whole View by organizing our research into
     lenses -- focused selections of our research addressing various business
     issues and technology topics -- within our three coverage areas: Internet
     Commerce, eBusiness Technology and Technographics Data & Analysis.

          TOOLS TO DEVELOP EBUSINESS STRATEGIES.  Our research and advisory
     services analyze technology and its relation to, and impact on, evolving
     markets and business issues. This enables our clients to:

           - assess potential new markets, competitors, products and services;

           - anticipate technology-driven business model shifts;

           - understand how the Internet and other emerging technologies can
             improve business processes;

           - educate and inform strategic decision makers in their
             organizations; and

           - capitalize on emerging technologies.

          EXPERTISE ON THE INTERNET AND EMERGING TECHNOLOGIES.  We started our
     business in 1983 and have a long history of and extensive experience in
     identifying emerging technology trends and providing research and
     actionable advice on the impact of technology on business. This history and
     experience allowed us early on to identify and analyze the impact that the
     Internet would have on businesses, consumers and society, and to launch our
     first Internet-focused research efforts in 1993. Our research analysts have
     many years of industry experience, are frequent speakers at business and
     technology conferences and symposiums, and are frequently quoted in the
     press and other publications. They enjoy direct access to the leaders and
     decision-makers within large enterprises, Internet companies and technology
     vendors. We provide our research analysts with rigorous training to ensure
     that they have the skills to challenge conventional viewpoints and provide
     prescriptive, actionable insight and research to achieve our key values.

          INTERNET-BASED, ACTIONABLE ERESEARCH THAT ACCELERATES
     DECISION-MAKING.  Our eResearch platform, specifically developed for
     electronic distribution and use over the Internet, increases the relevancy,
     timeliness and usefulness of our research. We distill the abundance of
     information, developments and data into concise and easy-to-read formats to
     facilitate rapid decision-making. Our web site offers advanced
     personalization features, downloadable data and graphics and intuitive
     navigation and search features which provide clients with the access and
     flexibility to accelerate deployment of our ideas and analysis.

          TIMELY INSIGHTS INTO CHANGING CONSUMER BEHAVIOR.  Our Technographics
     Data & Analysis coverage area and several of our bit products provide
     primary data, quantitative research and prescriptive advice to help our
     clients understand consumers' attitudes, abilities and motivations
     regarding the Internet and technology. We annually interview more than
     150,000 households in North America and Europe. Our clients use our
     Technographics research to assess specific consumer segment behavior,
     identify emerging consumer trends and adapt their business strategies
     accordingly.

FORRESTER'S STRATEGY

     We seek to maintain and enhance our position as a leading Internet research
firm and to capitalize on the growing demand for our research by:

          IDENTIFYING AND DEFINING NEW INTERNET BUSINESS MODELS, TECHNOLOGIES
     AND MARKETS.  We seek to position ourselves ahead of other research firms
     by delivering strategic research and analysis on the impact of the Internet
     and other new and emerging technologies on business models and technology
     infrastructure. We believe that our research methodology and our creative
     culture allow us to identify and analyze rapid shifts in the use of the
     Internet and other emerging technologies before these changes appear on the
     horizons of most users, vendors and other research firms. Our early
     identification of these shifts enables us to offer research and introduce
     new products and services that help our clients capitalize on the Internet
     and emerging business models.

          LEVERAGING ERESEARCH.  Our focus on sales of research that is produced
     for and delivered on the Internet allows us to provide value to our clients
     and increase our revenues. Our business model, eResearch technology
     platform and research methodology allow us to increase sales of existing
     products and to rapidly introduce new products and services without
     incurring significant incremental costs. We intend to continue to use the
     Internet to both increase sales of our research and introduce innovative
     products.

          EXPANDING MULTIPLE SALES CHANNELS.  We plan to continue to expand our
     direct sales force and to develop new methods to sell directly from our web
     site and through new on-line affiliates and intermediaries. We sell our
     products and services through our headquarters in Cambridge, Massachusetts,
     our European headquarters in Amsterdam, the Netherlands and our office in
     London. We are also in the process of opening remote sales offices in New
     York, Chicago and San Francisco. Our direct sales force increased 66% from
     92 on December 31, 1998 to 153 on December 31, 1999. As we continue to
     expand our direct sales force we seek to increase the average sales volume
     per sales representative, lengthen the average tenure of our sales
     representatives and sales management and shorten our sales cycle through
     marketing initiatives. In 1999, we introduced Baseline Research for
     Internet Entrepreneurs and the Baseline Affiliates Program to sell our
     research to the emerging market for Internet entrepreneurs through our web
     site and other affiliate web sites.

          GROWING OUR CLIENT BASE WORLDWIDE AND INCREASING SALES TO EXISTING
     CLIENTS.  We believe that our products and services can continue to be
     successfully marketed and sold to new client companies worldwide and to new
     organizations within existing client companies. We believe that within our
     client base of 1,793 clients as of December 31, 1999, there is ample
     opportunity to sell additional products and services. In addition, we
     intend to continue expanding our international presence as the growing use
     of the Internet and the need for e-business strategies increase the demand
     for external sources of objective research.

          ATTRACTING AND RETAINING OUTSTANDING RESEARCH PROFESSIONALS.  The
     knowledge and experience of our analysts are critical elements of our
     ability to provide high-quality products and services. Through our on-going
     recruiting efforts, we seek to hire outstanding research professionals from
     varied backgrounds and a wide range of industries. We believe that our
     culture, which emphasizes excellence, cooperation and creativity and
     fosters a dedication to quality research, helps us to attract and retain
     high-caliber research professionals. We provide a competitive compensation
     structure and recognition and rewards for excellent individual and team
     performance.

          OPTIMIZING THE USE OF NEW TECHNOLOGY.  Our eResearch platform allows
     us to conduct, design, sell and deliver our research over the Internet.
     Through this platform we can:

        - create Internet-based products that we sell on-line;

        - create research tools that allow us to perform research on the
          Internet;

        - conduct direct marketing campaigns;

                                        3
<PAGE>   5

        - improve sales leads fulfillment;

        - create links to on-line affiliates; and

        - accelerate the production of our research.

     We intend to continue to use emerging technologies to improve the reach and
quality of our research.

     Each of our coverage areas -- Internet Commerce, eBusiness Technology and
Technographics Data & Analysis -- includes research lenses that focus on
research relevant to specific business issues and topics. Within each coverage
area we offer three different levels of lenses:

        - a Comprehensive lens which contains all of the research within a
          particular coverage area;

        - Industry/Infrastructure lenses which provide research that is focused
          on a specific vertical market or a discrete element of technology
          infrastructure; and

BIT PRODUCTS

     Our bit products consist of research that is collected, analyzed and sold
directly on the Internet. Our bit products allow us to use the Internet as both
an active, real-time, research tool and a direct sales and distribution channel.
We use these products to provide clients with timely information, to collect
data at a low cost and to quickly access new markets that we previously did not
reach with our direct sales channel.

                                        5
<PAGE>   7

     We currently offer the following bit products:

     - THE eBUSINESS VOYAGE -- an on-line tool that allows businesses to assess
       their responses to the Internet and Internet technologies using a variety
       of metrics and permits them to benchmark their e-business development
       strategies against their peers and competitors.

     - POWERRANKINGS -- an on-line ranking of business web sites. We create our
       PowerRankings using on-line consumer surveys and unbiased expert
       analysis. PowerRankings provide objective research to help consumers
       choose leading Internet sites in different industries such as brokerage,
       toys and apparel and provide e-commerce vendors with an independent
       assessment of their efforts in the market.

     - BASELINE RESEARCH -- concise packages of research sold directly on our
       web site and through a network of affiliated web sites. This research
       offers small business executives, independent consultants and developers
       access to a limited group of research reports focused on a particular
       topic within a research lens.

     - INTERNET ADWATCH -- an interactive tracking tool that enables advertisers
       and publishers in the United Kingdom to monitor on-line advertising
       campaigns and spending. The service records advertising on hundreds of
       web sites. We combine this data with advertising rates, traffic
       information and submissions from the sites to estimate advertising
       spending levels.

     - INTERNET USER MONITOR -- an on-line survey of Internet users collected by
       placing "pop-up" questionnaires on major commercial web sites in the
       United Kingdom. This data is then cross-referenced with face-to-face
       consumer interviews to provide data on web users' attitudes and
       behaviors. In 1999, the Internet User Monitor surveyed approximately
       100,000 users on-line.

ADVISORY SERVICES

     Our advisory services provide a number of ways for our clients to interact
directly with our analysts. These services leverage our research expertise to
address clients' long-term planning issues and align our research and insight
with clients' specific goals. Our advisory service programs include:

     - Partners Program

     - eBusiness Review Program

     - Web Site Review Program

     - Strategy Workshops

     - Speeches

In addition to research lenses, clients purchasing a membership to a Partners
Program or an eBusiness Review Program engage in regular, structured
interactions with our analysts. These interactions may include advisory days
which consist of full day interactions with one or more of our analysts,
advisory calls which consist of two-hour phone conversations with our analysts,
and strategy workshops which allow clients to meet with both peer executives and
Forrester analysts. These clients also are assigned a navigator -- a proactive
research liaison who maintains an understanding of the client's business
objectives.

     Clients who join the Web Site Review Program receive targeted,
action-oriented assessments of their corporate web site and its role in their
company's on-line strategies. Our strategy workshops are full day presentations
and interactive exercises that focus on particular business and technology
issues. Recent workshops have included: Building Internet Customer Service,
Making Deals with Portals, The Future of Interactive Media, and Business Trade
and the Impact of New Channel Relationships. In addition, our clients may join
our research inquiry network, a call center with a staff dedicated to providing
additional information about our research, methodologies, coverage areas and
sources.

PRICING AND CONTRACT SIZE

     The prices for contracts that include only research are a function of the
number of lenses purchased and the number of research recipients within the
client organization. The average contract for annual memberships for research
only at December 31, 1999 was approximately $41,700, an increase of 41% from
$29,500 at December 31, 1998. The prices for contracts that include research and
advisory services are also a function of the number of lenses purchased, the
number of research recipients within the client organization and the amount and
type of advisory services. All memberships to our advisory services include
research. The average contract for an annual membership for our level one
Partners Program at December 31, 1999 was approximately $148,800, an increase of
20% from $124,200 at December 31, 1998. The average contract for an annual
membership for our level two Partners Program at December 31, 1999 was
approximately $61,700, an increase of 14% from $53,900 at December 31, 1998.

     We believe that the agreement value of contracts to purchase research and
advisory services provides a significant measure of our business volume. We
calculate agreement value as the total revenues recognizable from all research
and advisory service contracts in force at a given time without regard to how
much revenue has already been recognized. Agreement value grew 68% to $115.8
million at December 31, 1999 from $69.1 million at December 31, 1998.

RESEARCH ANALYSTS AND METHODOLOGY

     We employ a structured methodology in our research which enables us to
identify and analyze emerging technology trends, markets and audiences and
ensures consistent research quality and recommendations across all research
lenses. Our research provides consistent research themes and comprehensive
coverage of Internet and emerging technology issues across our coverage areas.

     Our research process subjects initial ideas to research, analysis and
rigorous validation, and produces conclusions, predictions and recommendations.
In the Internet Commerce and eBusiness Technology coverage areas, we use the
following primary research methods:

     - confidential interviews with early adopters of new technology, technology
       vendors and users and consumers;

     - regular briefings with vendors to review current positions and future
       directions; and

     - input from clients and third parties gathered during advisory sessions.

In the Technographics Data & Analysis coverage area, we combine our qualitative
research methodology with traditional survey research methodologies such as
correlations, frequencies, cross-tabulations and multi-variant statistics to
produce research reports, quantitative survey data and data insights. We use a
third-party data vendor for data collection and tabulation.

     Our research begins with discussion sessions with analysts where they
generate ideas for research. Analysts test ideas throughout the research report
process at informal and weekly research meetings. Our reports are consistent in
format and we require our analysts to write research reports in a structure that

                                        7
<PAGE>   9

combines graphics and easy-to-read text to deliver concise, decisive and
objective research to our clients. At the final stage of the research process,
senior analysts meet to test the conclusions of each research report. An analyst
who has not been involved in the creation of a particular report reviews the
report to ensure quality, clarity and readability. All research is reviewed and
graded by senior research management.

SALES AND MARKETING

     Our sales force is located primarily at our headquarters in Cambridge,
Massachusetts, our European headquarters in Amsterdam, the Netherlands and our
London office. We have made a substantial investment in our direct sales force
to better serve clients and address additional markets. We employed 153 sales
representatives as of December 31, 1999, an increase of 66% from 92 as of
December 31, 1998. Our direct sales force consists of:

     - account managers who are responsible for maintaining and leveraging the
       current client base by renewing and selling additional products and
       services to existing clients;

     - account executives who develop new business in assigned territories;

     - regional sales directors who focus on high-level client contact and
       service; and

     - telesales representatives who operate out of our headquarters in
       Cambridge.

     We also sell our research products directly on-line through our web site
and through a network of affiliate web sites that are authorized to sell limited
portions of our research on-line. We also use eight local independent sales
representatives to market and sell our products and services internationally in
Argentina, Australia, Brazil, Italy, Korea, Portugal, South Africa and Spain.

     Our marketing efforts are designed to increase awareness of the Forrester
brand and further our reputation as a leader in Internet and emerging
technologies research. We actively promote brand awareness through our web site,
Forum events, extensive worldwide press relations, and, direct mail campaigns.
We also employ an integrated direct marketing strategy that uses Internet, mail
and telephone channels for identifying and attracting high-quality sales leads.
We encourage our analysts to increase our visibility by having their research
ideas selectively distributed through various Internet, print and television
outlets.

     As of December 31, 1999, our research was delivered to 1,793 client
companies. As of December 31, 1999, our client companies included 18% of the
companies in the annual Global 2500, which we define as the 1,000 largest United
States public companies as listed in Fortune Magazine, the 500 largest private
companies as listed in Forbes Magazine and the 1,000 largest international
companies as listed in The Financial Times. No single client company accounted
for over 2% of our revenues for the year ended December 31, 1999.

COMPETITION

     We believe that the principal competitive factors in our industry include
the following:

     - independence from vendors and clients;

     - quality of research and analysis;

     - timely delivery of information;

     - the ability to leverage new technologies;

     - the ability to offer products that meet the changing needs of
       organizations for research and analysis;

     - customer service; and

     - price.

     We believe that we compete favorably with respect to each of these factors.
We believe that our early focus on eBusiness strategies and the Internet is a
significant competitive advantage. Additionally, we believe

                                        8
<PAGE>   10

that our advanced eResearch technology platform, our Whole View research
approach, and easy-to-read research format distinguish us from our competitors.

     We compete in the market for research on and about the Internet. Our
principal direct competitors include other independent providers of similar
services as well as Internet and digital media measurement services. In
addition, our indirect competitors include the internal planning and marketing
staffs of our current and prospective clients, as well as other information
providers such as electronic and print publishing companies, survey-based
general market research firms and general business consulting firms. Our
indirect competitors could choose to compete directly against us in the future.
In addition, there are relatively few barriers to entry into our market and new
competitors could readily seek to compete against us in one or more market
segments addressed by our research. Increased competition could adversely affect
our operating results through pricing pressure and loss of market share. There
can be no assurance that we will be able to continue to compete successfully
against existing or new competitors.

EMPLOYEES

     As of December 31, 1999, we employed a total of 446 persons, including 133
research staff, 212 sales and marketing personnel and 101 operations personnel.

     Our culture emphasizes certain key values -- client service, quality and
creativity -- that we believe are critical to our future growth. We promote
these values through rigorous training and frequent recognition for achievement.
We encourage teamwork and promote individuals who foster these values. Each new
employee that we hire undergoes a week-long training process. This training
includes presentations by our executives which focus on our corporate goals and
workshops and provides individuals with the skills necessary to achieve our key
values.

     All members of our research staff participate in our incentive compensation
bonus plan. Their performance is measured against individual and team goals to
determine an eligible bonus that is funded by our overall performance against
key business objectives. Individual and team goals include on-time delivery of
high-quality research and advisory services support to clients. In addition,
analysts, research directors and research management are eligible to receive
equity awards under our incentive stock option plan.

     All of our direct sales representatives participate in our annual
commission plan. Under this plan, we pay commissions monthly to sales personnel
based upon attainment of net bookings against established quotas. In addition,
all account managers, account executives, regional managers, and regional
directors are eligible to participate in our incentive stock option plan based
on performance.

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

OVERVIEW

     This Annual Report on Form 10-K contains forward-looking statements within
the meaning of the Private Securities Litigation Reform Act of 1995. Words such
as "expects," "anticipates," "intends," "plans," "estimates," or similar
expressions are intended to identify these forward-looking statements. These
statements are based on the Company's current plans and expectations and involve
risks and uncertainties that could cause actual future activities and results of
operations to be materially different from those set forth in the
forward-looking statements. The Company undertakes no obligation to update
publicly any forward-looking statements, whether as a result of new information,
future events, or otherwise.

     We are a leading independent Internet research firm that conducts research
and analysis on the impact of the Internet and emerging technologies on business
strategy, consumer behavior and society. Our clients, which include senior
management, business strategists and marketing and technology professionals
within large enterprises use our prescriptive, actionable research to understand
and capitalize on the Internet and emerging business models and technologies.

     We derive revenues from memberships to our core research and from our
advisory services and Forum events. We offer contracts for our products and
services that are typically renewable annually and payable in advance.
Accordingly, a substantial portion of our billings are initially recorded as
deferred revenue. Research revenues are recognized pro rata on a monthly basis
over the term of the contract. Our advisory services clients purchase such
services together with memberships to our research. Billings attributable to
advisory services are initially recorded as deferred revenue and recognized as
revenue when performed. Similarly, Forum billings are initially recorded as
deferred revenue and are recognized upon completion of each event.

     Our operating expenses consist of cost of services and fulfillment, selling
and marketing expenses, general and administrative expenses and depreciation and
amortization. Cost of services and fulfillment represent the costs associated
with the production and delivery of our products and services, and include the
costs of salaries, bonuses and related benefits for research personnel and all
associated editorial, travel and support services. Selling and marketing
expenses include salaries, employee benefits, travel expenses, promotional
costs, sales commissions and other costs incurred in marketing and selling our
products and services. General and administrative expenses include the costs of
the operations, technology, finance and strategy groups and our other
administrative functions.

     We believe that the "agreement value" of contracts to purchase research and
advisory services provides a significant measure of our business volume. We
calculate agreement value as the total revenues recognizable from all research
and advisory service contracts in force at a given time, without regard to how
much revenue has already been recognized. Agreement value increased 68% to
$115.8 million at December 31, 1999 from $69.1 million at December 31, 1998. No
single client accounted for more than 2% of agreement value at December 31,
1999. Our experience is that a substantial portion of client companies renew
expiring contracts for an equal or higher level of total research and advisory
service fees each year. Approximately 74% and 75% of our client companies with
memberships expiring during the years ended December 31, 1999 and 1998,
respectively, renewed one or more memberships for our products and services.
This renewal rate is not necessarily indicative of the rate of future retention
of our revenue base.

</TABLE>

YEARS ENDED DECEMBER 31, 1999 AND 1998

     REVENUES.  Total revenues increased 42% to $87.3 million in the year ended
December 31, 1999 from $61.6 million in the year ended December 31, 1998.
Revenues from core research increased 38% to $64.7 million in the year ended
December 31, 1999 from $46.8 million in the year ended December 31, 1998.
Increases in total revenues and revenues from core research were primarily
attributable to an increase in the number of client companies to 1,793 at
December 31, 1999 from 1,271 at December 31, 1998, an increase in the sales
organization to 153 employees at December 31, 1999 from 92 employees at December
31, 1998 and sales of additional core research to existing clients. No single
client company accounted for more than 2% of revenues for the year ended
December 31, 1999.

     Advisory services and other revenues increased 53% to $22.6 million in the
year ended December 31, 1999 from $14.7 million in the year ended December 31,
1998. This increase was primarily attributable to increased demand for
Forrester's advisory services programs and Forum events, an increase in the
number of events held to eight in the year ended December 31, 1999 from six in
the year ended December 31, 1998 and an increase in research staff providing
advisory services to 125 employees at December 31, 1999 from 97 at December 31,
1998.

     Revenues attributable to customers outside the United States increased 57%
to $19.8 million in the year ended December 31, 1999 from $12.6 million in the
year ended December 31, 1998. Revenues attributable to customers outside the
United States increased as a percentage of total revenues to 22% for the year
ended December 31, 1999 from 21% for the year ended December 31, 1998. The
increase in international revenues was primarily attributable to the continued
expansion of our European headquarters in Amsterdam, the Netherlands, including
an increase in sales personnel, and our acquisition of London-based Fletcher
Research Limited on November 15, 1999. We invoice our international clients,
other than clients billed by our subsidiary Fletcher Research Limited, in U.S.
dollars.

     COST OF SERVICES AND FULFILLMENT.  Cost of services and fulfillment
decreased as a percentage of total revenues to 32% in the year ended December
31, 1999 from 36% in the year ended December 31, 1998. These expenses increased
26% to $27.7 million in the year ended December 31, 1999 from $22.0 million in
the year ended December 31, 1998. The decrease in expenses as a percentage of
revenues reflects a larger revenue base in 1999 and lower production costs
resulting from the introduction of our eResearch platform in February 1999. The
expense increase in 1999 was principally due to an increase in research analyst
staffing and related compensation expenses.

                                       15
<PAGE>   17

     SELLING AND MARKETING.  Selling and marketing expenses increased as a
percentage of total revenues to 36% in the year ended December 31, 1999 from 34%
in the year ended December 31, 1998. These expenses increased 49% to $31.1
million in the year ended December 31, 1999 from $20.9 million in the year ended
December 31, 1998. The increase in expenses and the increase in expenses as a
percentage of revenues were principally due to the increase in the number of
direct sales personnel and related commission and travel expenses.

     GENERAL AND ADMINISTRATIVE.  General and administrative expenses remained
constant as a percentage of total revenues at 11% in the years ended December
31, 1999 and 1998. These expenses increased 48% to $9.9 million in the year
ended December 31, 1999 from $6.7 million in the year ended December 31, 1998.
The increase in expenses was principally due to staffing increases in our
operations, technology, finance and strategy groups.

     DEPRECIATION AND AMORTIZATION.  Depreciation and amortization expenses
increased 45% to $4.0 million in the year ended December 31, 1999 from $2.8
million in the year ended December 31, 1998. The increase in these expenses was
principally due to purchases of computer equipment, software, office furnishings
and leasehold improvements to support business growth, including our move to our
new headquarters in October 1999.

     COSTS RELATED TO ACQUISITION.  Costs related to acquisition totaled
$694,000 and resulted from our acquisition of Fletcher Research Limited on
November 15, 1999, which was accounted for as an immaterial pooling of
interests. These one-time, non-recurring costs consisted of legal, accounting,
investment banking, printing, filing and other related fees and expenses
incurred in completing this acquisition.

     OTHER INCOME, NET.  Other income, consisting primarily of interest income,
increased to $3.7 million in the year ended December 31, 1999 from $3.0 million
in the year ended December 31, 1998. The increase was due to interest income
from higher cash and marketable securities balances resulting from positive cash
flows from operations.

     INCOME TAX PROVISION.  During the year ended December 31, 1999, we recorded
a tax provision of $6.6 million, reflecting an effective tax rate of 37.5%.
During the year ended December 31, 1998, we recorded a tax provision of $4.6
million reflecting an effective tax rate of 37.8%. The decrease in effective tax
rate resulted from a reduction in our effective state tax rate and an increase
in our investments in tax-exempt marketable securities, offset by non-deductible
acquisition costs.

YEARS ENDED DECEMBER 31, 1998 AND DECEMBER 31, 1997

     REVENUES.  Total revenues increased 52% to $61.6 million in the year ended
December 31, 1998 from $40.4 million in the year ended December 31, 1997.
Revenues from core research increased 54% to $46.8 million in the year ended
December 31, 1998 from $30.4 million in the year ended December 31, 1997.
Increases in total revenues and revenues from core research were primarily
attributable to an increase in the number of client companies to 1,271 at
December 31, 1998 from 1,029 at December 31, 1997, sales of additional research
services to existing clients and the introduction of five new strategy research
services and one new quantitative research service since January 1, 1997.

     Advisory services and other revenues increased 47% to $14.7 million in the
year ended December 31, 1998 from $10.0 million in the year ended December 31,
1997. This increase was primarily attributable to demand for our advisory
services and the addition of three new Forum events in 1998.

     Revenues attributable to customers outside the United States increased 44%
to $12.6 million in the year ended December 31, 1998 from $8.8 million in the
year ended December 31, 1997 and decreased as a percentage of total revenues to
21% for the year ended December 31, 1998 from 22% for the year ended December
31, 1997. The increase in international revenues was primarily due to our
opening of our European headquarters in Amsterdam, the Netherlands in April
1998, and the addition of direct international sales personnel. During 1998, we
invoiced our international clients in U.S. dollars.

     Agreement value grew 48% to $69.1 million at December 31, 1998 from $46.6
million at December 31, 1997. No single client company accounted for more than
3% of agreement value at December 31, 1998 or 3% of revenues for the year ended
December 31, 1998.

                                       16
<PAGE>   18

     COST OF SERVICES AND FULFILLMENT.  Cost of services and fulfillment
increased as a percentage of total revenues to 36% in the year ended December
31, 1998 from 34% in the year ended December 31, 1997. These expenses increased
61% to $22.0 million in the year ended December 31, 1998 from $13.7 million in
the year ended December 31, 1997. The increase in expenses and expenses as a
percentage of total revenues was principally due to increased analyst staffing
for research services and related compensation expenses and the addition of
three new Forum events in 1998.

     SELLING AND MARKETING.  Selling and marketing expenses decreased as a
percentage of total revenues to 34% in the year ended December 31, 1998 from 35%
in the year ended December 31, 1997. These expenses increased 47% to $20.9
million in the year ended December 31, 1998 from $14.2 million in the year ended
December 31, 1997. The decrease as a percentage of total revenues resulted
principally from the larger revenue base in 1998. The increase in expenses was
principally due to the addition of direct salespersons and increased sales
commission expenses associated with increased revenues.

     GENERAL AND ADMINISTRATIVE.  General and administrative expenses remained
constant as a percentage of total revenues at 11% in the years ended December
31, 1998 and December 31, 1997. These expenses increased 49% to $6.7 million in
the year ended December 31, 1998 from $4.5 million in the year ended December
31, 1997. The increase in expenses was principally due to staffing increases and
costs associated with the opening of our European headquarters.

     DEPRECIATION AND AMORTIZATION.  Depreciation and amortization expense
increased 129% to $2.8 million in the year ended December 31, 1998 from $1.2
million in the year ended December 31, 1997. The increase in this expenses was
principally due to investments in our technology infrastructure and costs
associated with the opening of our European headquarters.

     OTHER INCOME, NET.  Other income, consisting primarily of interest income,
increased to $3.0 million in the year ended December 31, 1998 from $2.5 million
in the year ended December 31, 1997. This increase was due to interest income
from higher cash and marketable securities balances resulting from positive cash
flows from operations.

     INCOME TAX PROVISION.  During the year ended December 31, 1998, we recorded
a tax provision of $4.6 million, reflecting an effective tax rate of 37.8%.
During the year ended December 31, 1997, we recorded a tax provision of $3.7
million reflecting an effective tax rate of 39.7%. The decrease in effective tax
rate resulted from a reduction in our effective state tax rate and an increase
in sales through our foreign sales corporation, which we organized in 1998.

YEARS ENDED DECEMBER 31, 1997 AND DECEMBER 31, 1996

     REVENUES.  Total revenues increased 62% to $40.4 million in the year ended
December 31, 1997 from $25.0 million in the year ended December 31, 1996.
Revenues from core research increased 67% to $30.4 million in the year ended
December 31, 1997 from $18.2 million in the year ended December 31, 1996.
Increases in total revenues and revenues from core research were primarily
attributable to an increase in the number of client companies to 1,029 at
December 31, 1997 from 885 at December 31, 1996 and the introduction of six new
strategy research services since January 1, 1996. Revenues from our quantitative
research service were not material in 1997.

     Advisory services and other revenues increased 48% to $10.0 million in the
year ended December 31, 1997 from $6.8 million in the year ended December 31,
1996. This increase was primarily attributable to demand for the partners and
strategy review programs and the addition of two new Forum events in 1997.

     Revenues attributable to customers outside the United States increased 66%
to $8.8 million in the year ended December 31, 1997 from $5.3 million in the
year ended December 31, 1996 and also increased as a percentage of total
revenues to 22% for the year ended December 31, 1997 from 21% for the year ended
December 31, 1996. These increases were due primarily to the addition of direct
international sales personnel. During 1997, we invoiced our international
clients in U.S. dollars.

     Agreement value grew 55% to $46.6 million at December 31, 1997 from $30.0
million at December 31, 1996. No single client company accounted for more than
2% of agreement value at December 31, 1997 or 3% of revenues for the year ended
December 31, 1997.

     COST OF SERVICES AND FULFILLMENT.  Cost of services and fulfillment
decreased as a percentage of total revenues to 34% in the year ended December
31, 1997 from 35% in the year ended December 31, 1996. These expenses increased
56% to $13.7 million in the year ended December 31, 1997 from $8.8 million in
the year ended December 31, 1996. The expense increase in this period was
principally due to increased analyst staffing for strategy research services and
related compensation expenses. The decrease as a percentage of total revenues
was principally due to the larger revenue base.

     SELLING AND MARKETING.  Selling and marketing expenses decreased as a
percentage of total revenues to 35% in the year ended December 31, 1997 from 36%
in the year ended December 31, 1996. These expenses increased 58% to $14.2
million in the year ended December 31, 1997 from $9.0 million in the year ended
December 31, 1996. The increase in expenses was principally due to the addition
of direct salespersons and increased sales commission expenses associated with
increased revenues. The decrease as a percentage of total revenues was
principally due to increased productivity of our direct sales force.

     GENERAL AND ADMINISTRATIVE.  General and administrative expenses increased
as a percentage of total revenues to 11% in the year ended December 31, 1997
from 10% in the year ended December 31, 1996. These expenses increased 79% to
$4.5 million in the year ended December 31, 1997 from $2.5 million in the year
ended December 31, 1996. The increases in expenses and expenses as a percentage
of total revenues were principally due to staffing increases in operations and
technology, the addition of a human resources department and our investment in
new internal technology, including new financial systems.

     DEPRECIATION AND AMORTIZATION.  Depreciation and amortization expenses
increased 95% to $1.2 million in the year ended December 31, 1997 from $618,000
in the year ended December 31, 1996. The increase in these expenses was
principally due to purchases of computer equipment, software, office furnishings
and leasehold improvements to support business growth.

     OTHER INCOME, NET.  Other income, consisting primarily of interest income,
increased to $2.5 million in the year ended December 31, 1997 from $634,000 in
the year ended December 31, 1996. This increase resulted from our higher cash
and marketable securities balances resulting from positive cash flows from
operations and net proceeds from our initial public offering.

     INCOME TAX PROVISION.  During the year ended December 31, 1997, we recorded
a tax provision of $3.7 million, reflecting an effective tax rate of 39.7%.
During the year ended December 31, 1996, we recorded a pro forma tax provision
of $1.9 million reflecting an effective tax rate of 40.5%. The decrease in
effective tax rate resulted from a reduction in our effective state tax rate and
an increase in our investments in tax-exempt marketable securities.

RESULTS OF QUARTERLY OPERATIONS

     The following tables set forth a summary of our unaudited quarterly
operating results for each of our eight most recently ended fiscal quarters. We
have derived this information from our unaudited interim consolidated financial
statements, which, in the opinion of our management, have been prepared on a
basis consistent with our financial statements contained elsewhere in this
prospectus and include all adjustments, consisting only of normal recurring
adjustments, necessary for a fair presentation in accordance with generally
accepted accounting principles when read in conjunction with our consolidated
financial statements and related notes included elsewhere in this prospectus.
Historically, our total revenues, operating profit and net income in the fourth
quarter have reflected the significant positive contribution of revenues
attributable to advisory services performed and Forum events held in the fourth
quarter. As a result, we have historically experienced a decline in total
revenues, operating profit and net income from the quarter ended December 31 to
the quarter ended March 31. Our quarterly operating results are not necessarily
indicative of future results of operations.

LIQUIDITY AND CAPITAL RESOURCES

     We have financed our operations through funds generated from operations.
Memberships for research, which constituted approximately 74% of our revenues
for the year ended December 31, 1999, are generally annually renewable and are
payable in advance. We generated $31.9 million and $14.3 million in cash from
operating activities during the years ended December 31, 1999 and 1998,
respectively.

     In 1999, we used $39.1 million of cash in investing activities, consisting
primarily of $8.9 million for net purchases of property and equipment, $1.0
million for a minority investment in an Internet-based marketing research firm
and $29.8 million for net purchases of marketable securities. We regularly
invest excess funds in short- and intermediate-term interest-bearing obligations
of investment grade.

                                       19
<PAGE>   21

     We had $13.4 million of cash and cash equivalents and $85.3 million of
marketable securities at December 31, 1999. We do not have a line of credit and
do not anticipate the need for one in the foreseeable future. We plan to
continue to introduce new products and services and to invest in our
infrastructure over the next 12 months. We believe that our current cash and
marketable securities balances and cash flows from operations will satisfy
working capital, financing activities and capital expenditure requirements for
at least the next two years.

YEAR 2000 READINESS DISCLOSURE

     As of the date of this filing, we have not incurred any significant
business disruptions as a result of year 2000 issues. However, while no such
occurrence has developed, year 2000 issues that may arise related to key
suppliers and service providers may not become apparent immediately. We have
received assurances of year 2000 compliance from key suppliers. We have also
received assurances from key service providers such as financial institutions,
our payroll service provider and our retirement plan administrator as to their
year 2000 readiness. We can provide no assurance that we will not be adversely
affected by these suppliers and service providers due to noncompliance in the
future.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     The following discussion about our market risk disclosures involves
forward-looking statements. Actual results could differ materially from those
projected in the forward-looking statements. We are exposed to market risk
related to changes in interest rates and foreign currency exchange rates. We do
not use derivative financial instruments for speculative or trading purposes.

     INTEREST RATE SENSITIVITY.  We maintain an investment portfolio consisting
mainly of corporate obligations, federal agency obligations, state and municipal
bonds and Treasury notes with a weighted-average maturity of less than one year.
These held-to-maturity securities are subject to interest rate risk and will
fall in value if market interest rates increase. If market interest rates were
to increase immediately and uniformly by 10% from levels at December 31, 1999,
the fair market value of these investments would decline by an immaterial
amount. We have the ability to hold our fixed income investments until maturity.
Therefore, we would not expect our operating results or cash flows to be
affected to any significant degree by a sudden change in market interest rates
on our securities portfolio. The following table provides information about our
investment portfolio. For investment securities, the table presents principal
cash flows and related weighted average interest rates by expected maturity
dates.

interest rates):

     FOREIGN CURRENCY EXCHANGE.  On a global level, we face exposure to adverse
movements in foreign currency exchange rates. This exposure may change over time
as business practices evolve and could have a material adverse impact on our
financial results. Historically, our primary exposure had been related to non-
dollar-denominated operating expenses in Europe, Canada and Asia, where we sell
primarily in U.S. dollars. The introduction of the Euro as a common currency for
members of the European Monetary Union took place in our fiscal year 1999. We
have not determined what impact, if any, the Euro will have on foreign exchange
exposure. We are prepared to hedge against fluctuations the Euro will have on
foreign exchange exposure if this exposure becomes material. As of December 31,
1999, the total assets related to non-dollar-denominated currencies was
approximately $2.6 million.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Stockholders of
  Forrester Research, Inc.:

     We have audited the accompanying consolidated balance sheets of Forrester
Research, Inc. (a Delaware corporation) and subsidiaries as of December 31, 1998
and 1999 and the related consolidated statements of income, stockholders' equity
and comprehensive income and cash flows for each of the three years in the
period ended December 31, 1999. 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 Forrester Research, Inc. and
subsidiaries as of December 31, 1998 and 1999, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1999, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES

     Forrester Research, Inc. (the Company) is a leading independent Internet
research firm that conducts research and analysis on the impact of the Internet
and emerging technologies on business strategy, consumer behavior and society.
The Company is incorporated under the laws of the State of Delaware and grants
credit to its customers with locations throughout the world.

     The accompanying consolidated financial statements reflect the application
of certain significant accounting policies as described below and elsewhere in
the accompanying financial statements and notes.

  PRINCIPLES OF CONSOLIDATION

     The accompanying financial statements include the accounts of the Company
and its wholly owned subsidiaries. All significant intercompany balances have
been eliminated in consolidation.

  MANAGEMENT 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 these estimates.

  REVENUE RECOGNITION

     The Company generally invoices its core research, advisory and other
services when an order is received. The gross amount is recorded as accounts
receivable and deferred revenue when the client is obligated to pay the invoice.
Core research, which represents the distribution of research reports as well as
data research, is recorded as revenue ratably over the term of the agreement.
Advisory and other services are recognized during the period in which the
services are performed.

  DEFERRED COMMISSIONS

     Commissions incurred in acquiring new or renewal contracts are deferred and
charged to operations as the related revenue is recognized. The Company
evaluates the recoverability of deferred commissions at each balance sheet date.

  NET INCOME PER COMMON SHARE

     Basic net income per common share is computed by dividing net income by the
basic weighted average number of common shares outstanding during the period.
Diluted net income per common share is computed by dividing net income by the
diluted weighted average number of common and common equivalent shares
outstanding during the period. The weighted average number of common equivalent
shares outstanding has been determined in accordance with the treasury-stock

  PRODUCT DEVELOPMENT

     All costs associated with the development of new products and services are
expensed as incurred.

  CONCENTRATION OF CREDIT RISK

     Statement of Financial Accounting Standards (SFAS) No. 105, Disclosure of
Information About Financial Instruments with Off-Balance-Sheet Risk and
Financial Instruments with Concentrations of Credit Risk, requires disclosure of
any significant off-balance-sheet and credit risk concentrations. The Company
has no significant off-balance sheet concentration of credit risk such as
foreign exchange contracts, option contracts or other foreign hedging
arrangements. Financial instruments that potentially subject the Company to
concentrations of credit risk are principally cash equivalents, marketable
securities and accounts receivable. The Company places its investments in highly
rated institutions. No single customer accounted for greater than 10% of
revenues or accounts receivable in any of the periods presented.

  FINANCIAL INSTRUMENTS

     SFAS No. 107, Disclosures About Fair Value of Financial Instruments,
requires disclosure about the fair value of financial instruments. Financial
instruments consist of cash equivalents, marketable securities, accounts
receivable and accounts payable. The estimated fair value of these financial
instruments approximates their carrying value. The fair market value of
marketable securities is based on market quotes. The Company's cash equivalents
and marketable securities are generally investment grade corporate bonds and
obligations of the federal government or municipal issuers.

  FOREIGN CURRENCY

     The functional currency of the Company's wholly owned subsidiaries in the
United Kingdom and the Netherlands are the local currency. The financial
statements of the subsidiaries are translated to United States dollars using
period-end exchange rates for assets and liabilities and average exchange rates
during the corresponding period for revenues and expenses. Translation gains and
losses as a result of this translation are accumulated as a component of
accumulated other comprehensive income (loss). Net gains and losses resulting
from foreign exchange transactions are included in the consolidated statements
of operations and were not significant during the periods presented.

  COMPREHENSIVE INCOME

     SFAS No. 130, Reporting Comprehensive Income, requires disclosure of the
components of comprehensive income, which is defined as the change in equity of
a business enterprise during a period from transactions and other events and
circumstances from non-owner sources. Comprehensive income is disclosed in the
accompanying statements of stockholders' equity and comprehensive income. The
components of accumulated other comprehensive income as of December 31, 1998 and

  CAPITALIZED SOFTWARE COSTS

     In March 1998, the American Institute of Certified Public Accountants
(AICPA) issued Statement of Position (SOP) No. 98-1, Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use. SOP No. 98-1 requires
certain computer software costs associated with internal-use software to be
expensed as incurred until certain capitalization criteria are met. The Company
adopted SOP No. 98-1 beginning January 1, 1999. SOP No. 98-1 had no effect upon
adoption. The net book value of capitalized internal use software costs at
December 31, 1998 and 1999 was approximately $1,920,000 and $3,420,000,
respectively.

  ORGANIZATIONAL COSTS

     In April 1998, the AICPA issued SOP No. 98-5, Reporting on the Costs of
Start-Up Activities which requires that all nongovernmental entities expense the
costs of start-up activities, including organizational costs, as those costs are
incurred. The Company has historically recorded all such costs as expenses in
the period incurred.

  NEW ACCOUNTING STANDARDS

     In December 1999, the Securities and Exchange Commission (SEC) issued Staff
Accounting Bulletin (SAB) No. 101, Revenue Recognition in Financial Statements.
SAB No. 101 is effective for all periods beginning after December 15, 1999.
Adoption of SAB No. 101 is not expected to have a material impact on the
Company's consolidated financial position or results of operations.

     In June 1998, the Financial Accounting Standards Board (FASB) issued SFAS
No. 133, Accounting for Derivative Instruments and Hedging Activities. SFAS No.
133 is effective for all periods beginning after June 15, 2000 and establishes
methods of accounting for derivative financial instruments and hedging
activities related to those instruments as well as other hedging activities.
Adoption of SFAS No. 133 is not expected to have a material impact on the
Company's consolidated financial position or results of operations.

(2) ACQUISITION

     On November 15, 1999, the Company acquired 100% of the outstanding shares
of Fletcher Research Limited (Fletcher). The transaction has been accounted for
as a pooling of interests. However, Fletcher's historical financial position and
results of operations were not material to the Company's financial position and
results of operations. Accordingly, the historical financial statements of the
Company have not been restated. The Company incurred approximately $694,000 of
various costs including legal, accounting, investment

transaction, which has been separately stated in the accompanying consolidated
statement of income for the year ended December 31, 1999.

(3) CASH, CASH EQUIVALENTS AND MARKETABLE SECURITIES

     The Company considers all short-term, highly liquid investments with
maturities of 90 days or less from the original date of purchase to be cash
equivalents.

     The Company accounts for investments in accordance with SFAS No. 115,
Accounting for Certain Investments in Debt and Equity Securities. Under SFAS No.
115, securities purchased in order to be held for indefinite periods of time and
not intended at the time of purchase to be held until maturity are classified as
available-for-sale securities. At December 31, 1998 and 1999, these securities
consisted of investments in federal and state government obligations and
corporate obligations, which were recorded at fair market value, with any
unrealized gains and losses reported as a separate component of other
accumulated comprehensive income (loss). There were no held-to-maturity or
trading securities at December 31, 1998 and 1999.

     At December 31, 1998 and 1999, marketable securities consisted of the

(4) INVESTMENT IN GREENFIELD ONLINE

     In May 1999, the Company invested $1.0 million in a holding company that is
the majority shareholder of Greenfield Online, Inc., an Internet-based marketing
research firm. As a result of this investment, the Company effectively owns
approximately a 3.4% interest in Greenfield Online, Inc. This investment is
being accounted for using the cost method and, accordingly, is being valued at
cost unless a permanent impairment in its value occurs or the investment is
liquidated. As of December 31, 1999, the Company has determined that a permanent
impairment has not occurred.

     During the year ended December 31, 1999, the Company charged approximately
$220,000 to cost of services and fulfillment related to services provided by
Greenfield Online.

     The Company and George F. Colony, who was the sole stockholder of the
Company prior to its initial public offering, have entered into an
indemnification agreement relating to their respective income tax liabilities.
Mr. Colony will continue to be liable for personal income taxes on the Company's
income for all periods prior to the time the Company ceased to be an S
corporation, while the Company will be liable for all income taxes subsequent to
the time it ceased to be an S corporation. The agreement generally provides that
the Company will indemnify Mr. Colony for any increase in his taxes (including
interest and penalties) resulting from adjustments initiated by taxing
authorities and from payments to him under the agreement and Mr. Colony will pay
to the Company an amount equal to any decrease in his tax liability resulting

  INCREASE IN AUTHORIZED SHARES AND STOCK SPLIT

     On February 7, 2000, the Company increased the number of authorized shares
of common stock from 25,000,000 to 125,000,000 and effected a two-for-one stock
split as a 100% stock dividend. The Company has retroactively restated all share
and per share amounts for the periods presented to give effect to this stock
split.

  PUBLIC OFFERING

     Also in February 2000, the Company issued 626,450 shares of common stock in
a public offering that generated net proceeds to the Company of approximately
$22,600,000.

  PREFERRED STOCK

     The Company has authorized 500,000 shares of $.01 par value preferred
stock. The Board of Directors has full authority to issue this stock and to fix
the voting powers, preferences, rights, qualifications, limitations or
restrictions thereof, including dividend rights, conversion rights, redemption
privileges and liquidation preferences and the number of shares constituting any
series or designation of such series.

(9) STOCK OPTION PLANS

     In February 1996, the Company adopted the Forrester Research, Inc. 1996
Equity Incentive Plan, which has been subsequently amended (the Plan). The Plan
provides for the issuance of incentive stock options (ISOs) and nonqualified
stock options (NSOs) to purchase up to 10,500,000 shares of common stock. Under
the terms of the Plan, ISOs may not be granted at less than fair market value on
the date of grant (and in no event less than par value). ISO grants to holders
of 10% of the combined voting power of all classes of Company stock must be
granted at an exercise price not less than 110% of the fair market value at the
date of grant. Options generally vest ratably over three years and expire after
10 years. Options granted under the Plan immediately vest upon certain events,
as defined.

     In September 1996, the Company adopted the 1996 Stock Option Plan for
Non-Employee Directors (the Directors' Plan), which provides for the issuance of
options to purchase up to 300,000 shares of common stock. Under the Directors'
Plan, each non-employee director shall be awarded options to purchase 12,000
shares of common stock, at an exercise price equal to the fair market value of
the common stock upon his or her election as a director. These options vest in
three equal annual installments commencing on the date of grant. In addition,
each non-employee director will also receive an option to purchase 8,000 shares
of common stock, at an exercise price equal to the fair market value of the
common stock, each year immediately following the Company's annual stockholders'
meeting. These options will vest in three equal installments on the first,
second and third anniversaries of the date of grant. The Compensation Committee
(the Committee) of the Board of Directors also has the authority under the
Directors' Plan to grant options to non-employee directors in such amounts and
on such terms as set forth in the Directors' Plan as it shall determine at the
time of grant.

     SFAS No. 123, Accounting for Stock-Based Compensation, requires the
measurement of the fair value of stock options or warrants to be included in the
statement of income or disclosed in the notes to financial statements. The
Company has determined that it will continue to account for stock-based
compensation for employees under Accounting Principles Board Opinion No. 25 and
elect the disclosure-only alternative under SFAS No. 123. The Company has
computed the value of options granted during the years ended December 31, 1997,

each purchase period under the Stock Purchase Plan, the maximum number of shares
of common stock that may be purchased by an employee is limited to the number of
shares equal to $12,500 divided by the fair market value of a share of common
stock on the first day of the purchase period. An employee may elect to have up
to a maximum of 10% deducted from his or her regular salary for the purpose of
purchasing shares under the Stock Purchase Plan. The price at which the
employee's shares are purchased is the lower of (a) 85% of the closing price of
the common stock on the day that the purchase period commences or (b) 85% of the
closing price of the common stock on the day that the purchase period
terminates. Shares purchased by employees under the Stock Purchase Plan are as

(11) SEGMENT AND ENTERPRISE WIDE REPORTING

     The Company adopted SFAS No. 131, Disclosures About Segments of an
Enterprise and Related Information, in the fiscal year ended December 31, 1998.
SFAS No. 131 establishes selected standards for reporting information regarding
operating segments in annual financial statements and requires selected
information for those segments to be presented in interim financial reports
issued to stockholders. SFAS No. 131 also establishes standards for related
disclosures about products and services and geographic areas. Operating segments
are defined as components of an enterprise about which separate discrete
financial information is evaluated regularly by the chief operating decision
maker, or decision making group, in deciding how to allocate resources and
assess performance. The Company's chief decision-making group, as defined under
SFAS No. 131, is the Executive Team, consisting of Mr. Colony and the executive
officers. To date, the Company has viewed its operations and managed its
business as principally one segment, research services. As a result, the
financial information disclosed herein materially represents all of the
financial information related to the Company's principal operating segment.
Foreign assets represent less than 2% of total consolidated assets for all
periods presented.

     Net revenues by geographic destination and as a percentage of total
revenues for the years ended December 31, 1997, 1998 and 1999 are as follows (in
thousands):

                            FORRESTER RESEARCH, INC.


     Forrester Research, Inc., a corporation organized and existing under and by
virtue of the General Corporation Law of the State of Delaware, does here
certify:

     FIRST:    That Article 4. of the Certificate of Incorporation be amended as
follows:

          "The total number of shares of stock that this corporation shall have
authority to issue is 125,500,000 shares consisting of (i) 125,000,000 Common
Stock, par value $.01 per share ("Common Stock") and (ii) 500,000 shares of
Preferred Stock, $0.1 par value per share ("Preferred Stock").

     The following is a statement of the designations and the powers, privileges
and rights, and the qualifications, limitations or restrictions thereof in
respect of each class of capital stock of this corporation.


1.   COMMON STOCK.

     A.   GENERAL. The voting, dividend and liquidation rights of the holders
of the Common Stock are subject to and qualified by the rights of the holders
of the Preferred Stock of any series as may be designated by the board of
directors upon any issuance of the Preferred Stock of any series. The holders
of the Common Stock shall have no preemptive rights to subscribe for any shares
of any class of stock of this corporation whether now or hereafter authorized.

     B.   VOTING. The holders of the Common Stock are entitled to one vote for
each share held at all meetings of stockholders. There shall be no cumulative
voting.

     The number of authorized shares of Common Stock may be increased or
decreased (but not below the number of shares thereof then outstanding) by the
affirmative vote of the holders of a majority of the stock of this corporation
entitled to vote, irrespective of the provisions of Section 242(b)(2) of the
General Corporation Law of the State of Delaware.

     C.   DIVIDENDS. Dividends may be declared and paid on the Common Stock
from funds lawfully available therefor as and when determined by the board of
directors and subject to any preferential dividend rights of any then
outstanding Preferred Stock.

     D.   LIQUIDATION. Upon the dissolution or liquidation of this corporation,
whether voluntary or involuntary, holders of Common Stock will be entitled to
receive all assets of this corporation available for distribution to its
stockholders, subject to any preferential rights of any then outstanding
Preferred Stock.

     E.   PREFERRED STOCK.
<PAGE>   2
     Preferred Stock may be issued from time to time in one or more series, each
of such series to have such terms as stated or expressed herein and in the
resolution or resolutions providing for the issue of such series adopted by the
board of directors as hereinafter provided. Any shares of Preferred Stock which
may be redeemed, purchased or acquired by this corporation may be reissued
except as otherwise provided by law or this Certificate of Incorporation.
Different series of Preferred Stock shall not be construed to constitute
different classes of shares for the purposes of voting by classes unless
expressly provided in the resolution or resolutions providing for the issue of
such series adopted by the board of directors as hereinafter provided.

     Authority is hereby expressly granted to the board of directors from time
to time to issue the Preferred Stock in one or more series, and in connection
with the creation of any such series, by resolution or resolutions providing for
the issue of the shares thereof, to determine and fix such voting powers, full
or limited, or no voting powers, and such designations, preferences and relative
participating, optional or other special rights, and qualifications, limitations
or restrictions thereof, including without limitation thereof, dividend rights,
conversion rights, redemption privileges and liquidation preferences, as shall
be stated and expressed in such resolutions, all to the full extent now or
hereafter permitted by the General Corporation Law of the State of Delaware.
Without limiting the generality of the foregoing, the resolutions providing for
issuance of any series of Preferred Stock may provide that such series shall be
superior or rank equally or be junior to the Preferred Stock of any other series
to the extent permitted by law and this Certificate of Incorporation. Except as
otherwise provided in this Certificate of Incorporation, no vote of the holders
of the Preferred Stock or Common Stock shall be prerequisite to the designation
or issuance of any shares of any series of the Preferred Stock authorized by and
complying with the conditions of this Certificate of Incorporation, the right to
have such vote being expressly waived by all present and future holders of the
capital stock of this corporation.

     SECOND: That the said amendment was duly adopted, consented to and
authorized by the majority of the shareholders entitled to vote thereon in a
special meeting of stockholders consent in accordance with the provisions of
Section 242 of the General Corporation Law of the State of Delaware.

     2.2  LIMITATION ON SHELF REGISTRATION OBLIGATION

     Notwithstanding the provisions of Section 2.1, and subject to the
limitations described below in this Section 2 and Section 3, Buyer shall not be
obligated to effect the filing of a Registration Statement pursuant to this

Directors of Buyer, it would not be in the best interests of Buyer and its
stockholders for such Registration Statement to be filed under the circumstances

Registration Statement, for a period of not more than 90 days; PROVIDED,

Statement filed pursuant to this Section 2 effective until November 30, 2000. If
Buyer utilizes the right set forth in this Section 2, the Registration Period
shall be extended for the number of days for which any filing was deferred as
specified in the notice; PROVIDED, HOWEVER, that the Registration Period need
not be extended pursuant to this subsection by a period of longer than six
months.

     2.3    SELLING PROCEDURES; SUSPENSION

     Each Holder of Registrable Securities agrees to give written notice to the
Buyer at least two (2) Business Days prior to any intended sale or distribution
of Registrable Securities under the Shelf Registration Statement referred to in
Section 2.1, which notice shall specify the date on which such Holder intends to
begin such sale or distribution. As soon as practicable after the date such
notice is received by Buyer, and in any event within two (2) Business Days after
such date, Buyer shall comply with either paragraph (a) or (b) below.

          (a) Unless paragraph (b) below applies, Buyer shall (i) if deemed
necessary by Buyer, prepare and file with the Commission a post-effective
amendment to the Shelf Registration Statement or a supplement to the related
Prospectus or a supplement or amendment to any document incorporated therein by
reference or file any other required document so that such Registration
Statement will not contain an untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading, and so that, as thereafter delivered to
purchasers of the Registrable Securities being sold thereunder, such Prospectus
will not contain an untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading; (ii) provide the Holders of the Registrable Securities who gave such
notice copies of any documents filed pursuant to Section 2.3(a)(i); and (iii)
inform each such Holder that Buyer has complied with its obligations in Section
2.3(a)(i) (or that, if Buyer has filed a post-effective amendment to the Shelf
Registration Statement which has not yet been declared effective, Buyer will
notify each such Holder to that effect, will use its reasonable efforts to
secure the effectiveness of such post-effective amendment and will immediately
notify each such Holder pursuant to Section 2.3(a)(i) hereof when the amendment
has become effective). Each Holder who has given notice of intention to
distribute such Holder's Registrable Securities in accordance with Section 2.3
hereof (a "NOTICE HOLDER") shall sell all or any of such Registrable Securities
pursuant to the Shelf Registration Statement and related Prospectus only during
the 90-day period commencing with the date on which Buyer gives notice, pursuant
to Section 2.3(a)(iii), that the Registration Statement and Prospectus may be
used for such purpose (such 90-day period is referred to as a "SELLING PERIOD").
The Notice Holders will not sell any Registrable Securities pursuant to such
Registration Statement or Prospectus after such Selling Period without giving a
new notice of intention to sell pursuant to

                                      -21-
<PAGE>   5

Section 2.3 hereof and receiving a further notice from Buyer pursuant to Section
2.3(a)(iii) hereof or paragraph (b) below.

          (b) In the event of (i) any request by the Commission or any other
federal or state governmental authority during the period of effectiveness of
the Shelf Registration Statement for amendments or supplements to a Shelf
Registration Statement or related Prospectus or for additional information; (ii)
the issuance by the Commission or any other federal or state governmental
authority of any stop order suspending the effectiveness of a Shelf Registration
Statement or the written threat or initiation of any proceedings for that
purpose; (iii) the receipt by Buyer of any notification with respect to the
suspension of the qualification or exemption from qualification of any of the
Registrable Securities for sale in any jurisdiction or the initiation or
threatening of any proceeding for such purpose; (iv) any event or circumstance
which necessitates the making of any changes in the Shelf Registration Statement
or Prospectus, or any document incorporated or deemed to be incorporated therein
by reference, so that, in the case of the Shelf Registration Statement, it will
not contain any untrue statement of a material fact or any omission to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and that in the case of the Prospectus, it will not
contain any untrue statement of a material fact or any omission to state a
material fact required to be stated therein or necessary to make the statements
therein, in the light of the circumstances under which they were made, not
misleading; (v) that Buyer is in possession of material information that it
deems advisable not to disclose in a Registration Statement or (vi) that, in the
good faith judgment of Buyer's Board of Directors, it is advisable to suspend
use of the Prospectus (a "SUSPENSION") for a discrete period of time due to
pending corporate developments, public filings with the Commission or similar
events; then, subject to paragraph (d) below, Buyer shall deliver a certificate
in writing to the Notice Holders (the "SUSPENSION NOTICE") to the effect of the
foregoing and, upon receipt of such Suspension Notice, each such Notice Holder's
Selling Period will not commence until such Notice Holder's receipt of copies of
the supplemented or amended Prospectus provided for in Section 2.3(a)(i) hereof,
or until it is advised in writing by Buyer that the Prospectus may be used, and
has received copies of any additional or supplemental filings that are
incorporated or deemed incorporated by reference in such Prospectus.

          (c) In the event any of the events or circumstances listed in the
foregoing paragraph (b) occur or exist after a Selling Period has commenced,
subject to paragraph (d) below, Buyer shall have the same right to suspend such
Selling Period by delivery of a Suspension Notice as Buyer would have had if the
Selling Period had not yet commenced, and any such suspension of a Selling
Period shall be deemed included within the meaning of the term "Suspension" for
all purposes under this Agreement.

          (d) In the event of any Suspension, or any delay in effecting the
Shelf Registration under Section 2.2 above, Buyer will use its reasonable
efforts to ensure that the use of the Prospectus so suspended or delayed may be
commenced or resumed, as the case may be, and that any Selling Period so
suspended will commence or resume, as the case may be, as

                                      -22-

<PAGE>   6

soon as practicable and, in the case of a pending development, filing or event
referred to in Section 2.3(b)(iv) or (v) hereof, as soon, in the judgment of
Buyer's Board of Directors, as disclosure of the material relating to such
pending development, filing or event would not have an adverse effect on Buyer's
ability to consummate the transaction, if any, to which such development, filing
or event relates. Notwithstanding any other provision of this Agreement, Buyer
shall have the right to cause a maximum of two (2) Suspensions, neither of which
may be within 30 days of the other, as provided above (including for this
purpose a delay in effecting the Shelf Registration pursuant to Section 2.2
above) during any 12-month period after the initial effective date of the Shelf
Registration Statement, and the total number of days in any 12-month period
during which a Suspension or Suspensions (including for this purpose a delay in
effecting the Shelf Registration Statement pursuant to Section 2.2 above) may be
in effect shall not exceed 90 days.

          (e) Subject to the provisions of Section 2.2, Buyer will use its
reasonable efforts to maintain the effectiveness until November 30, 2000 of any
Registration Statement pursuant to which any of the Registrable Securities are
being offered. Buyer from time to time will amend or supplement such
Registration Statement and the Prospectus contained therein to the extent
necessary to comply with the 1933 Act and any applicable state securities
statute or regulation. Buyer will also provide each holder of Registrable
Securities with as many copies of the Prospectus contained in any such
Registration Statement as it may reasonably request.

     3.   RESTRICTIONS ON TRANSFER OF SHARES; RULE 144 AVAILABILITY

          (a) The Holders agree, understand and acknowledge that the issuance of
the Registrable Securities to the Holders has not been, and, except as
contemplated in this Agreement, the sale or other disposition thereof by the
Holders will not be, registered under the 1933 Act or the securities laws of any
state and that the transfer, sale, disposal or assignment of such shares is
subject to restriction as set forth in Section 6.10 and 6.11 of the Purchase
Agreement and will bear the legends set forth in those Sections. The Holders
acknowledge that, except as expressly set forth in this Agreement, the Holders
have no right to require Buyer to cause the registration of any Registrable
Securities.

          (b) With a view to making available to the Holders the benefits of
Rule 144 promulgated under the 1933 Act and Form S-3 and any other rule or
regulation of the Commission that may at any time after the Release Date permit
such Holder to sell securities of the Company to the public without
registration, the Company agrees to use its best efforts to:


          (i)  make and keep public information available, as those terms are
               understood and defined in Rule 144 under the 1933 Act;

                                      -23-

<PAGE>   7
           (ii) file with the Commission in a timely manner all reports and
                other documents required of the Company under the 1933 Act and
                the 1934 Act; and

          (iii) furnish to any holder of Registrable Shares upon request a

                written statement by the Company as to its compliance with the
                reporting requirements of said Rule 144 and of the 1933 Act and
                the 1934 Act, a copy of the most recent annual or quarterly
                report of the Company, and such other reports and documents of
                the Company as such holder may reasonably request to avail
                itself of any similar rule or regulation of the Commission
                allowing it to sell any such securities without registration.

     4.    EXPENSES

     Buyer will pay all Registration Expenses in connection with the
registration of Registrable Securities effected by Buyer pursuant to Section 2.
Holders of Registrable Securities registered pursuant to this Agreement shall
pay all Selling Expenses associated with such registration, with each Holder
bearing a pro rata portion of the Selling Expenses based upon the number of
Registrable Securities registered by each Holder.

     5.    EXPIRATION OF REGISTRATION RIGHTS

     The obligations of Buyer under Section 2 of this Agreement to register the
Registrable Securities shall expire and terminate at such time as the
Shareholders shall be entitled or eligible to sell all such securities in the
United States or to a U.S. person (as defined in Regulation S under the 1933
Act) without restriction and without a need for the filing of a registration
statement under the 1933 Act. The obligations of Buyer under Section 2 of this
Agreement shall expire on November 30, 2000 (provided no stop transfer orders
are in place with the transfer agent).

     6.    REGISTRATION PROCEDURES

     In connection with the registration of Registrable Securities under this
Agreement, and subject to the other provisions of this Agreement, Buyer shall:

          (a) use its reasonable efforts to cause the Registration Statement
filed in accordance with Section 2 to become effective as soon as practicable
after the Release Date;

          (b) prepare and file with the Commission such amendments and
supplements to such Registration Statement and the Prospectus used in connection
therewith as may be necessary to keep such Registration Statement continuously
effective for the shorter of (i) the duration of its registration obligations
pursuant to Section 2, or (ii) until there are no

                                      -24-

<PAGE>   8

Registrable Securities outstanding, and to comply with the provisions of the
1933 Act with respect to the disposition of the Registrable Securities;

          (c) furnish to each Seller of such Registrable Securities such number
of copies of the Prospectus included in such Registration Statement as such
Seller may reasonably request in order to facilitate the sale or disposition of
such Registrable Securities;

          (d) use its reasonable efforts to register or qualify all securities
covered by such Registration Statement under such other securities or "blue sky"
laws of such jurisdictions as each Seller shall reasonably request, and do any
and all other acts and things as may be reasonably necessary to enable such
Seller to consummate the disposition in such jurisdictions of its Registrable
Securities covered by such Registration Statement, except that Buyer shall not
for any such purpose be required to qualify generally to do business as a
foreign corporation in any jurisdiction wherein it is not so qualified, or to
subject itself to taxation in respect of doing business in any such
jurisdiction, or to consent to general service of process in any such
jurisdiction;

          (e) notify each Seller of Registrable Securities covered by such
Registration Statement, at any time when a Prospectus relating thereto is
required to be delivered under the 1933 Act, of the happening of any event as a
result of which the Prospectus included in such Registration Statement, as then
in effect, includes an untrue statement of a material fact or omits to state any
material fact required to be stated therein or necessary to make the statements
therein not misleading in light of the circumstances then existing or if it is
necessary to amend or supplement such Prospectus to comply with the law, and at
the request of any such Seller, prepare and furnish to such Seller a reasonable
number of copies of a supplement to or an amendment of such Prospectus as may be
necessary so that, as thereafter delivered to the purchasers of such Registrable
Securities or securities, such Prospectus, as amended or supplemented, will
comply with the law;

          (f) use its best efforts to comply with all applicable rules and
regulations of the Commission;

          (g) use its best efforts to qualify such securities for listing on the
Nasdaq National Market, and provide a transfer agent and registrar for such
Registrable Securities not later than the effective date of such Registration
Statement; and

          (h) issue to any person to which any Holder of Registrable Securities
may sell such Registrable Securities in connection with such registration
certificates evidencing such Registrable Securities without any legend
restricting the transferability of the Registrable Securities.

     Buyer will promptly amend or supplement such Registration Statement and the
Prospectus contained therein whenever and to the extent necessary to comply with
the 1933


                                      -25-

<PAGE>   9

Act and any applicable state securities statute or regulation. Buyer will also
provide the Holder of Registrable Securities with as many copies of the
Prospectus contained in any such Registration Statement as it may reasonably
request.

     7.    1934 ACT REGISTRATION

     Buyer shall timely file with the Commission such information as the
Commission may require under Section 13 or 15(d) of the 1934 Act; and in such
event, Buyer shall use its best efforts to take all action pursuant to Rule
144(c) as may be required as a condition to the availability of Rule 144 under
the 1933 Act (or any successor exemptive rule hereinafter in effect) with
respect to such Common Stock. Buyer shall furnish to any holder of Registrable
Securities forthwith upon request (i) a written statement by Buyer as to its
compliance with the reporting requirements of Rule 144(c), (ii) a copy of the
most recent annual or quarterly report of Buyer as filed with the Commission,
and (iii) such other publicly-filed reports and documents as a holder may
reasonably request in availing itself of any rule or regulation of the
Commission allowing a holder to sell any such Registrable Securities without
registration.

     8.    SHAREHOLDER INFORMATION

     It shall be a condition precedent to the obligations of Buyer to take any
action pursuant to this Agreement that all Holders shall furnish to Buyer such
information regarding themselves, the Registrable Securities held by them and
the intended method of disposition of such Registrable Securities as shall be
reasonably required to effect the registration of their Registrable Securities
and to execute such documents in connection with such registration as Buyer may
reasonably request. In addition, each Holder agrees to dispose of any
Registrable Securities included in any registration only in accordance with the
plan of distribution described in the Registration Statement.

     9.    INDEMNIFICATION AND CONTRIBUTION

     In the event any Registrable Securities are included in a Registration
Statement under this Agreement:

          (a) In the event of any registration of any Registrable Securities
under the 1933 Act pursuant to this Agreement, then to the extent permitted by
law, Buyer will indemnify and hold harmless each Seller and any of his agents,
and any underwriter (as defined in the 1933 Act) for such Seller and each
person, if any, who controls such Seller or underwriter within the meaning of
the 1933 Act or the 1934 Act, against any losses, claims, damages, liabilities
and expenses (including reasonable attorneys fees) (joint or several) to which
they may become subject under the 1933 Act, the 1934 Act or other federal or
state law, insofar as such losses, claims, damages, liabilities and expenses
(including reasonable attorneys fees (or actions in respect thereof) arise out
of or are based upon any of the following statements, omissions or violations
(the following are collectively referred to as a


                                      -26-

<PAGE>   10

"VIOLATION"): (i) any untrue statement or alleged untrue statement of a material
fact contained in such Registration Statement, including any preliminary
prospectus or final prospectus contained therein or any amendments or
supplements thereto; (ii) the omission or alleged omission to state therein a
material fact required to be stated therein, or necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading; or (iii) any violation or alleged violation by Buyer of the 1933
Act, the 1934 Act, any state securities law or any rule or regulation
promulgated under the 1933 Act, the 1934 Act or any state securities law; and
Buyer will reimburse each such Seller, his agent, underwriter or controlling
person for any reasonable legal or other expenses reasonably incurred by them in
connection with investigating or defending any such loss, claim, damage,
liability or action. Notwithstanding anything contained in this Agreement to the
contrary, the indemnity agreement contained in this Section 9 shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability or action
if such settlement is effected without the consent of Buyer (which consent shall
not be unreasonably withheld, conditioned or delayed), nor shall Buyer be liable
in any such case for any such loss, claim, damage, liability or action to the
extent that it arises out of or is based upon a Violation which occurs in
reliance upon and in conformity with written information furnished to Buyer
expressly for use in connection with such registration by any such Seller,
underwriter or controlling person.

          (b) In the event of any registration of any Registrable Securities
under the 1933 Act pursuant to this Agreement, then to the extent permitted by
law, each Seller will indemnify and hold harmless Buyer, each of its officers,
directors, agents or employees, any underwriter (as defined in the 1933 Act) and
each person, if any, who controls Buyer or any underwriter for Buyer within the
meaning of the 1933 Act or the 1934 Act, and any other Seller or any of his
agents, underwriter or any person who controls such Seller within the meaning of
the 1933 Act or the 1934 Act, against any losses, claims, damages or liabilities
and expenses (including reasonable attorneys fees) (joint or several) to which
Buyer or any such director, officer, partner, agent, employee, controlling
person or underwriter, or other such Seller or agent, underwriter or controlling
person may become subject, under the 1933 Act, the 1934 Act or other federal or
state law, insofar as such losses, claims, damages, liabilities and expenses
(including reasonable attorneys fees) (or actions in respect thereto) arise out
of or are based upon any Violation, in each case to the extent (and only to the
extent) that such Violation occurs in reliance upon and in conformity with
written information furnished by such Seller expressly for use in connection
with such registration; and each such Seller will reimburse any reasonable legal
or other expenses reasonably incurred by Buyer or any such director, officer,
partner, agent, employee, controlling person or underwriter, other Seller,
agent, underwriter or controlling person in connection with investigating or
defending any such loss, claim, damage, liability or action. Notwithstanding
anything contained in this Agreement to the contrary, the indemnity agreement
contained in this Section 9(b) shall not apply to amounts paid in settlement of
any such loss, claim, damage, liability or action if such settlement is effected
without the consent of the Seller (which consent shall not be unreasonably
withheld, conditioned or delayed) provided further, that the aggregate liability
of each Seller in connection with any sale of Registrable Securities pursuant to
a Registration


                                      -27-

<PAGE>   11

Statement in which a Violation occurred shall be limited to the net proceeds
from such sale received by such Seller.

          (c) Promptly after receipt by an indemnified party under this Section
9 of notice of the commencement of any action (including any governmental
action), such indemnified party will, if a claim in respect thereof is to be
made against any indemnifying party under this Section 9, deliver to the
indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the fees and expenses to be paid
by the indemnifying party, if representation of such indemnified party by the
counsel retained by the indemnifying party would be inappropriate due to actual
or potential differing or conflicting interests between such indemnified party
and any other party represented by such counsel in such proceeding. The failure
to deliver written notice to the indemnifying party within a reasonable time of
the commencement of any such action, to the extent prejudicial to its ability to
defend such action, shall relieve such indemnifying party of liability to the
indemnified party under this Section 9 to the extent of such prejudice, but the
omission so to deliver written notice to the indemnifying party will not relieve
it of any liability that it may have to any indemnified party otherwise than
under this Section 9.

          (d) If recovery is not available under the foregoing indemnification
provisions of this Section 9, for any reason other than as specified therein,
the parties entitled to indemnification by the terms thereof shall be entitled
to contribution to liabilities and expenses in such proportion as is appropriate
to reflect the relative fault of the indemnifying parties and the indemnified
parties, except to the extent that contribution is not permitted under Section
11(f) of the 1933 Act. The relative fault of such indemnifying party and
indemnified party shall be determined by reference to, among other things, the
parties' relative knowledge and access to information concerning the matter with
respect to which the claim was asserted, the opportunity to correct and prevent
any statement or omission and any other equitable considerations appropriate
under the circumstances, including, without limitation, whether any untrue
statement or alleged untrue statement of a material fact or omission or alleged
omission to state a material fact relates to information supplied by Buyer, on
the one hand, or by the Seller, on the other hand. Buyer and the Seller of the
Registrable Securities covered by such Registration Statement agree that it
would not be equitable if the amount of such contribution were determined by pro
rata or per capita allocation. No Seller of Registrable Securities covered by
such Registration Statement or person controlling such Seller shall be obligated
to make any contribution hereunder which in the aggregate exceeds the net
proceeds from the Registrable Securities sold by such Seller, less the aggregate
amount of any damages which such Seller and its controlling persons have
otherwise been required to pay in respect of the same claim or any substantially
similar claim. The obligations of such Sellers to contribute are


                                      -28-

<PAGE>   12

several in proportion to their respective ownership of the Registrable
Securities covered by such Registration Statement and not joint.

     10.   NON-ASSIGNABILITY OF REGISTRATION RIGHTS

     The rights to cause Buyer, or its successors or assigns, to register
Registrable Securities pursuant to this Agreement are reserved solely for the
use and benefit of the Holders and may not be assigned or transferred by the
Holders to any other person; PROVIDED, HOWEVER, that any Holder who is a natural
person may transfer Registrable Securities to any member of the immediate family
of a Holder who is a natural person, or any trust or other fiduciary arrangement
for the benefit of such family member.

     11.   MISCELLANEOUS

     11.1  AMENDMENTS AND WAIVERS

     Any provision of this Agreement may be amended and the observance thereof
may only be waived (either generally or in a particular instance and either
retroactively or prospectively), with the written consent of Buyer and the
Holders of at least two thirds of the Registrable Securities then outstanding.
Any amendment or waiver effected in accordance with this Section shall be
binding upon each Holder of Registrable Securities at the time outstanding, each
future Holder of Registrable Securities, and Buyer.

     11.2  NOTICES

     Any notice required or permitted to be given hereunder shall be in writing
and shall be deemed given at the opening of business on the first Business Day
following the time (a) delivery is made, if by hand delivery, (b) the facsimile

                            INDEMNIFICATION AGREEMENT
                            -------------------------

     This Indemnification Agreement is made and entered into this 28th day of
February, 2000 ("AGREEMENT"), by and between Forrester Research, Inc., a
Delaware corporation (the "COMPANY") and the persons listed as Selling
Stockholders on the signature pages hereto (the "Selling Stockholders". Unless
otherwise defined herein, terms defined in the Underwriting Agreement, dated as
of February 22, 2000 (the "UNDERWRITING AGREEMENT") among the Company, the
Selling Stockholders and the other stockholders of the Company party thereto,
Goldman, Sachs & Co., Adams, Harkness & Hill, Inc., Thomas Weisel Partners LLC,
FAC/Equities, a division of First Albany Corporation and William Blair &
Company, L.L.C., as representatives of the several underwriters (collectively,
the "UNDERWRITERS") and used herein shall have the meanings given to them in the
Underwriting Agreement.

                                    RECITALS

     WHEREAS, the Company has filed a Registration Statement on Form S-3 (File
No. 333-95663) (the "REGISTRATION STATEMENT") with the Securities and Exchange
Commission to register 3,269,450 shares of common stock, $0.01 per value per
share ("Common Stock"), of the Company;

     WHEREAS, pursuant to the Underwriting Agreement, the Selling Stockholders,
other stockholders of the Company and the Company will sell Shares of Common
Stock to the Underwriters; and

     WHEREAS, under the Underwriting Agreement, the Selling Stockholders are
obligated to indemnify the Underwriters under the circumstances set forth
therein and the Company wishes to indemnify the Selling Stockholder for certain
of such indemnification obligations.

     NOW, THEREFORE, in consideration of the premises and the covenants
contained herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Company and the Selling
Stockholders do hereby covenant and agree as follows:

                                    AGREEMENT

     1.   DEFINITIONS. Terms defined in the Underwriting Agreement and not
otherwise defined herein are used herein with the meanings so defined.

     2.   INDEMNIFICATION. The Company shall indemnify and hold harmless each of
the Selling Stockholders against any losses, claims, damages or liabilities
(collectively, the


<PAGE>   2
 "DAMAGES") for which such Selling Stockholder indemnifies any Underwriter
pursuant to Section 8 of the Underwriting Agreement and will reimburse each
Selling Stockholder for any legal or other expenses reasonably incurred by such
Selling Stockholder in connection with defending any action or claim for which
such Selling Stockholder is entitled to indemnification hereunder; PROVIDED,
HOWEVER, that the Company shall not be required to indemnify and hold harmless
any Selling Stockholder for such Damages to the extent that such Damages arise
out of or are based upon an untrue statement or alleged untrue statement or
omission or alleged omission made in any Preliminary Prospectus, the
Registration Statement or the Prospectus or any amendment or supplement thereto
in reliance upon and in conformity with written information furnished by such
Selling Stockholders to the Underwriters through Goldman, Sachs & Co. expressly
for use therein.

     3.   PROCEDURE. Promptly after a Selling Stockholder has received notice of
or has knowledge of any claim by an Underwriter for which the Company is
obligated to indemnify such Selling Stockholder pursuant to Section 2 above (a
"CLAIM"), such Selling Stockholder shall, as a condition precedent to a Claim
with respect thereto being made against the Company, give the Company written
notice of such Claim. Such notice shall state the nature and the basis of such
Claim and a reasonable estimate of the amount thereof. The Company shall have
right to defend and settle, at its own expense and by its own counsel, any such
Claim. Such Selling Stockholder shall cooperate with the Company and its counsel
in the defense thereof and in any settlement. If the Company desires to accept a
final and complete settlement of any such Claim and such Selling Stockholder
unreasonably refuses to consent to such settlement, then the Company's liability
under Section 2 with respect to such Claim shall be limited to the amount so
offered in settlement by such Underwriter and such Selling Stockholder shall
reimburse the Company for any additional costs of defense which it subsequently
incurs with respect to such Claim.

     4.   GENERAL PROVISIONS.

          (a)  AMENDMENT. This Agreement may not be amended except by an
instrument in writing signed by the parties hereto.

          (b)  SEVERABILITY. If any term or other provision of this Agreement is
invalid, illegal or incapable of being enforced by any rule of law, or public
policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect so long as the economic or legal substance of
the transactions contemplated hereby is not affected in any manner adverse to
any party. Upon such determination that any term or other provision is invalid,
illegal or incapable of being enforced, the parties hereto shall negotiate in
good faith to modify this Agreement so as to effect the original intent of the
parties as closely as possible in an acceptable manner to the end that the
transactions contemplated hereby are fulfilled to the fullest extent possible.

                                      -2-

          (c)  ASSIGNMENT. No party may assign this Agreement or delegate its
obligations hereunder without, in the case of the Company, each of the Selling
Stockholders, and, in the case of a Selling Stockholder, without the consent of
the Company.

          (d)  PARTIES IN INTEREST. This Agreement shall be binding upon and
inure solely to the benefit of each party hereto and its successors and
permitted assigns and nothing in this Agreement, express or implied, is intended
to or shall confer upon any other person any right, benefit or remedy of any
nature whatsoever under or by reason of this Agreement.

          (e)  GOVERNING LAW. This Agreement has been executed as an agreement
under seal and shall be governed by, and construed in accordance with, the laws
of The Commonwealth of Massachusetts without giving effect to the conflict of
laws principles thereof.

          (f)  COUNTERPARTS. This Agreement may be executed in one or more
counterparts, and by the different parties hereto in separate counterparts, each
of which when executed shall be deemed to be an original but all of which taken
together shall constitute one and the same agreement.

                                  RISK FACTORS

     Investing in our common stock involves a high degree of risk. You should
carefully consider the risks and uncertainties described below before purchasing
our common stock. If any of the following risks actually occur, our business,
financial condition or results of operations could be harmed. In that case, the
trading price of our common stock could decline, and you could lose all or part
of your investment.

IF WE DO NOT ATTRACT AND RETAIN QUALIFIED PROFESSIONAL STAFF, WE WILL NOT BE
ABLE TO MAINTAIN OUR POSITION IN THE MARKET OR GROW OUR BUSINESS

     Our future success will depend in large measure upon the continued
contributions of our senior management team, research analysts and experienced
sales and marketing personnel. Thus, our future operating results will be
largely dependent upon our ability to retain the services of these individuals
and to attract additional qualified people from a limited pool of qualified
candidates. We experience intense competition in hiring and retaining
professionals from developers of Internet and emerging technology products,
other research firms, management consulting firms, print and electronic
publishing companies and financial services companies. Many of these firms have
substantially greater ability, either through cash or equity, to attract and
compensate qualified people. In addition, the Internet has created many
opportunities for people with the skills we seek to form their own companies or
join start-up companies, and these opportunities frequently offer the potential
for significant future financial profit through equity incentives that we cannot
match. If we lose professionals or are unable to attract new talent to
Forrester, we will not be able to maintain our position in the market or grow
our business.

IF WE DO NOT MANAGE OUR GROWTH EFFECTIVELY, IT COULD ADVERSELY AFFECT OUR
ABILITY TO GROW REVENUE AND COULD INCREASE OUR OPERATING EXPENSES

     Our growth has placed significant demands on our management and other
resources. Our revenues increased approximately 42% to $87.3 million in the year
ended December 31, 1999 from $61.6 million in the year ended December 31, 1998.
Our ability to effectively manage growth will require us to continue to develop
and improve our operational, financial, electronic research collection and
distribution, technology and other internal systems. We must also continue to
expand our business development capabilities and continue to train, motivate and
manage our employees. If we are unable to effectively manage our growth, it
would have an adverse effect on the quality of our products and services, our
ability to retain key personnel and to grow revenue and could increase our
operating expenses.

OUR OPERATING RESULTS FLUCTUATE AND OUR STOCK PRICE MAY BE VOLATILE AS A RESULT

     Our revenues and earnings may fluctuate from quarter to quarter based on a
variety of factors, many of which are beyond our control. The factors include,
but are not limited to:

     - the timing and size of new and renewal memberships for our research from
       clients;

     - the timing of revenue-generating Forum events sponsored by us;

     - the utilization of our advisory services by our clients;

     - the introduction and marketing of new products and services by us and our
       competitors;

     - the hiring and training of new analysts and sales personnel;

     - changes in demand for our research; and

     - general economic conditions.

     As a result, our operating results in future quarters may be below the
expectations of securities analysts and investors which could have an adverse
effect on the market price for our

                                        4
<PAGE>   2

common stock. Factors such as announcements of new products, services, offices
or strategic alliances by us or our competitors, as well as market conditions in
the Internet and emerging technologies services industry, may have a significant
impact on the market price of our common stock. The market price for our common
stock may also be affected by movements in prices of stocks in general.

A DECLINE IN RENEWALS FOR OUR MEMBERSHIP-BASED RESEARCH SERVICES COULD ADVERSELY
AFFECT OUR REVENUES

     Our success depends in large part upon renewals of memberships for our
research products. Approximately 74% of our revenues in the year ended December
31, 1999 were derived from our membership-based research products. In addition,
approximately 74% of our client companies with memberships expiring during this
period renewed one or more memberships for our products and services. A
significant decline in renewal rates for our research products could have an
adverse effect on our revenues.

LOSS OF KEY MANAGEMENT COULD AFFECT OUR ABILITY TO RUN OUR BUSINESS

     Our future success will depend in large part upon the continued services of
a number of our key management employees. The loss of any one of them, in
particular George F. Colony, our founder and Chairman, President and Chief
Executive Officer, could adversely affect our business.

IF WE DO NOT ANTICIPATE AND RESPOND TO MARKET TRENDS, WE MAY NOT REMAIN
COMPETITIVE

     Our success depends in part upon our ability to anticipate rapidly changing
technologies and market trends and to adapt our research to meet the changing
information needs of our clients. The technology and commerce sectors that we
analyze undergo frequent and often dramatic changes. The changes include:

     - the introduction of new products and obsolescence of others;

     - the use of technology to transform existing and create new business
       models;

     - shifting strategies and market positions of major industry participants;

     - paradigm shifts in system architectures; and

     - changing objectives and expectations of users of technology.

     The environment of rapid and continuous change presents significant
challenges to our ability to provide our clients with current and timely
analysis, strategies and advice on issues of importance to them. Meeting these
challenges requires the commitment of substantial resources. Any failure to
continue to provide insightful and timely analysis of developments, technologies
and trends in a manner that meets market needs could have an adverse effect on
our market position and results of operations.

IF WE DO NOT DEVELOP AND OFFER NEW PRODUCTS AND SERVICES, WE COULD LOSE OUR
COMPETITIVE POSITION AND FAIL TO GROW OUR BUSINESS

     Our future success will depend in part on our ability to offer new products
and services. These new products and services must successfully gain market
acceptance by addressing specific industry and business organization sectors,
anticipating and identifying changes in client requirements and changes in the
technology industry. The process of internally researching, developing,
launching and gaining client acceptance of a new product or service, or
assimilating and marketing an acquired product or service, is risky and costly.
We may not be able to introduce new, or assimilate acquired, products or
services successfully. Our failure to do so would adversely affect our ability
to maintain a competitive position in our market and continue to grow our
business.

<PAGE>   3

THE MARKET FOR RESEARCH PRODUCTS AND SERVICES IS COMPETITIVE AND IF WE FAIL TO
COMPETE EFFECTIVELY, WE COULD LOSE OUR MARKET POSITION

     We compete in the market for research products and services with other
independent providers of similar services. We may also face increased
competition from Internet-based research firms. Some of our competitors have
substantially greater financial, information-gathering and marketing resources
than we do. In addition, our indirect competitors include the internal planning
and marketing staffs of our current and prospective clients, as well as other
information providers such as electronic and print publishing companies,
survey-based general market research firms and general business consulting
firms. Our indirect competitors may choose to compete directly against us in the
future. In addition, there are relatively few barriers to entry into our market
and new competitors could readily seek to compete against us in one or more
market segments addressed by our products and services. Increased competition
could adversely affect our operating results through pricing pressure and loss
of market share.

IF WE FAIL TO INTEGRATE OUR RECENTLY COMPLETED ACQUISITION EFFECTIVELY, IT COULD
ADVERSELY AFFECT OUR OPERATING EXPENSES AND COULD CAUSE US TO FAIL TO ACHIEVE
THE BENEFITS WE EXPECTED

     We recently acquired Fletcher Research Limited, an Internet research
company located in the United Kingdom. It was our first acquisition and our
management has had no experience to date integrating acquisitions into our
business. The integration of any acquisition can be disruptive, divert
management time and attention and result in a failure to realize the expected
benefits of the acquisition. The problems may be accentuated where the acquired
company is foreign and located far from our headquarters. If we do not integrate
the Fletcher acquisition effectively, we could fail to achieve the benefits we
expected.

OUR CHAIRMAN AND CEO HAS SIGNIFICANT VOTING POWER AND MAY EFFECTIVELY CONTROL
THE OUTCOME OF ANY STOCKHOLDER VOTE

     George F. Colony, our Chairman, President and Chief Executive Officer,
beneficially owns approximately 46% of our common stock. As a result, he has the
ability to substantially influence, and may effectively control, the outcome of
corporate actions requiring stockholder approval, including the election of
directors. This concentration of ownership may also have the effect of delaying
or preventing a change in control of Forrester even if such a change of control
would benefit other investors.

OUR CORPORATE GOVERNANCE PROVISIONS MAY DETER A FINANCIALLY ATTRACTIVE TAKEOVER
ATTEMPT

     Provisions of our charter and by-laws may discourage, delay or prevent a
merger or acquisition that stockholders may consider favorable, including
transactions in which stockholders would receive a premium for their shares.
These provisions include the following:

     - any action to be taken by stockholders must be taken at a meeting and may
       not be taken by written consent;

     - stockholders must comply with advance notice requirements before raising
       a matter at a meeting of stockholders or nominating a director for
       election;

     - only our chairman, chief executive officer or, if there is none, the
       president or the board of directors may call a special meeting of
       stockholders;

     - our board of directors is divided into three classes and the members may
       be removed by the stockholders only for cause; and

     - our board of directors has the authority, without further action by the
       stockholders, to fix the rights and preferences of and issue shares of
       preferred stock.
