clients, which include senior management, business strategists, and information
technology ("IT") professionals within large enterprises, use Forrester's
prescriptive research to understand and benefit from current developments in
technology and as support for their development and implementation decisions.
    
 
   
     Forrester offers its clients annual memberships to any of its 10 research
services. Each research service focuses on a particular area of technology and

results, investment priorities, organizational effectiveness, and staffing
requirements. Forrester also provides advisory services to a limited number of
clients to help them explore in greater detail the topics covered by the core
research.

(1) The Company has elected to be taxed, since January 1, 1987, under subchapter
    S of the Internal Revenue Code of 1986, as amended (the "Code"), whereby the
    sole stockholder is liable for individual federal and state income taxes on
    the Company's taxable income. Upon the completion of this offering, the
    Company will terminate its S corporation election and will be subject to
    corporate-level federal and state income taxes. Accordingly, the pro forma
    income tax adjustments represent the income taxes that would have been
    recorded if the Company had been a C corporation for the periods presented.
    See Note 3 of Notes to Financial Statements.
 
   
(2) Pro forma net income per common share is computed by dividing pro forma net
    income by the weighted average number of shares of common stock and common
    stock equivalents outstanding during the period. See Note 1 of Notes to
    Financial Statements.
    
 
   
(3) Pro forma to give effect to the (i) distribution of previously undistributed
    S corporation earnings taxed or taxable to the Company's sole stockholder of
    approximately $3,600,000 based on earnings through September 30, 1996, and
    (ii) termination of the Company's S corporation election and the recognition
    of a net deferred income tax liability of approximately $500,000 as of
    September 30, 1996. See Notes 1 and 3 of Notes to Financial Statements.
    
 
   
(4) Does not include an adjustment for the distribution to be made to the sole
    stockholder of the Company after completion of this offering in an amount
    equal to the Company's undistributed S corporation earnings from October 1,
    1996 through the termination of the Company's S corporation election.
    
 
(5) Adjusted to reflect the sale of 2,000,000 shares of Common Stock at an
    assumed initial public offering price of $14.00 per share (less estimated
    underwriting discount and offering expenses).

                                  RISK FACTORS
 
     In addition to the other information contained in this Prospectus, the
following risk factors should be considered in evaluating the Company and its
business before purchasing the Common Stock offered by this Prospectus.
 
NEED TO ATTRACT AND RETAIN PROFESSIONAL STAFF
 
     The Company's future success will depend in large measure upon the
continued contributions of its senior management team, research analysts, and
experienced sales personnel. Accordingly, future operating results will be
largely dependent upon the Company's ability to retain the services of these
individuals and to attract additional qualified personnel from a limited pool of
qualified candidates. The Company experiences intense competition in hiring and
retaining professional personnel from, among others, producers of information
technology products, other research firms, management consulting firms, print
and electronic publishing companies, and financial services companies. Many of
these firms have substantially greater financial resources than the Company to
attract and compensate qualified personnel. The loss of the services of key
management and professional personnel or the inability to attract such personnel
could have a material adverse effect on the Company's business, financial
condition, and results of operations.
 
MANAGEMENT OF GROWTH
 
   
     The Company's growth has placed significant demands on its management and
other resources. The Company's revenues increased approximately 50% to $14.6
million in 1995 from $9.7 million in 1994 and increased 80% to $16.4 million in
the nine months ended September 30, 1996 from $9.1 million in the nine months
ended September 30, 1995. The Company's staff increased from 61 full-time
employees on January 1, 1995 to 119 full-time employees on September 30, 1996
and further increases are expected during the remainder of 1996. The Company's
ability to manage growth, if any, effectively will require it to continue to
develop and improve its operational, financial, and other internal systems, as
well as its business development capabilities, and to train, motivate, and
manage its employees. In addition, the Company may acquire complementary
businesses, products, or technologies, although it currently has no commitments
or agreements to do so. The Company's management has limited experience
integrating acquisitions. If the Company is unable to manage its growth
effectively, such inability could have a material adverse effect on the quality
of the Company's products and services, its ability to retain key personnel and
its business, financial condition, and results of operations.
    
 
VARIABILITY OF QUARTERLY OPERATING RESULTS; POSSIBLE VOLATILITY OF STOCK PRICE
 
     The Company's revenues and earnings may fluctuate from quarter to quarter
based on a variety of factors including the timing and size of new and renewal
memberships from clients, the timing of revenue-generating events sponsored by
the Company, the utilization of its advisory services, the introduction and
marketing of new products and services by the Company and its competitors, the
hiring and training of new analysts and sales personnel, changes in demand for
the Company's research, and general economic conditions. As a result, the
Company's operating results in future quarters may be below the expectations of
securities analysts and investors which could have a material adverse effect on
the market price for the Company's Common Stock. In addition, the stock market
recently has experienced volatility which has affected the market price of
securities of many companies and which has sometimes been unrelated to the
operating performance of such companies. Factors such as announcements of new
services or offices or strategic alliances by the Company or its competitors, as
well as market conditions in the information technology services industry, may
have a significant impact on the market price of the Common Stock. The market
price for the Company's Common Stock may also be affected by movements in prices
of stocks in general.
 
                                        5
<PAGE>   7
 
DEPENDENCE ON RENEWALS OF MEMBERSHIP-BASED RESEARCH SERVICES
 
   
     The Company's success depends in part upon renewals of memberships for its
core research products. Approximately 70% and 77% of the Company's revenues in
1995 and the first nine months of 1996, respectively, were derived from the
Company's membership-based core research products. A decline in renewal rates
for the Company's core research products could have a material adverse effect on
the Company's business, financial condition, and results of operations.
    
 
DEPENDENCE ON KEY PERSONNEL
 
     The Company's future success will depend in large part upon the continued
services of a number of key employees. The loss of key personnel, in particular
George F. Colony, the Company's founder and Chairman of the Board of Directors,
President, and Chief Executive Officer, would have a material adverse effect on
the Company's business, financial condition, and results of operations. The
Company has entered into a registration rights and non-competition agreement
with Mr. Colony which provides that if Mr. Colony's employment with the Company
is terminated he will not compete with the Company for the one-year period
following his termination. See "Business -- Employees" and "Management --
Registration Rights and Non-Competition Agreement".
 
RISKS ASSOCIATED WITH ANTICIPATING MARKET TRENDS
 
   
     The Company's success depends in part upon its ability to anticipate
rapidly changing technologies and market trends and to adapt its core research
to meet the changing information needs of the Company's clients. The technology
sectors that the Company analyzes undergo frequent and often dramatic changes,
including the introduction of new products and obsolescence of others, shifting
strategies and market positions of major industry participants, paradigm shifts
with respect to system architectures, and changing objectives and expectations
of users of technology. The environment of rapid and continuous change presents
significant challenges to the Company's ability to provide its clients with
current and timely analysis, strategies, and advice on issues of importance to
them. Meeting these challenges requires the commitment of substantial resources,
and any failure to continue to provide insightful and timely analysis of
developments, technologies, and trends in a manner that meets market needs could
have a material adverse effect on the Company's business, financial condition,
and results of operations.
    
 
NEW PRODUCTS AND SERVICES
 
     The Company's future success will depend in part on its ability to offer
new products and services that successfully gain market acceptance by addressing
specific industry and business organization sectors, 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 inherently risky and costly. There can be no assurance that the
Company's efforts to introduce new, or assimilate acquired, products or services
will be successful.
 
COMPETITION
 
     The Company competes in the market for research products and services with
other independent providers of similar services. Several of the Company's
competitors have substantially greater financial, information-gathering, and
marketing resources than the Company. In addition, the Company's indirect
competitors include the internal planning and marketing staffs of the Company's
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. The Company's indirect competitors
may choose to compete directly against the Company in the future. In addition,
there are relatively few barriers to entry into the Company's market and new
competitors could readily seek to compete against the Company in one or more
market segments addressed by the Company's products and services. Increased
competition could
 
                                        6
<PAGE>   8
 
adversely affect the Company's operating results through pricing pressure and
loss of market share. There can be no assurance that the Company will be able to
continue to compete successfully against existing or new competitors. See
"Business -- Competition".
 
CONCENTRATION OF CONTROL
 
     Upon completion of this offering, Mr. Colony will beneficially own
approximately 74% of the Company's outstanding Common Stock. As a result, he
will have the ability to elect the Company's directors and to determine the
outcome of corporate actions requiring stockholder approval. This concentration
of ownership may have the effect of delaying or preventing a change in control
of the Company. See "Management" and "Description of Capital Stock".
 
INTERNATIONAL OPERATIONS
 
   
     Revenues attributable to customers outside the United States represented
approximately 18% and 21% of the Company's total revenues for the year ended
December 31, 1995 and for the nine months ended September 30, 1996,
respectively. The Company expects that international revenues will continue to
account for a substantial portion of total revenues and intends to continue to
expand its international operations. Expansion into new geographic territories
requires considerable management and financial resources and may negatively
impact the Company's near-term results of operations. The Company's
international operations are subject to numerous inherent challenges and risks,
including developing and managing relationships with international sales
representative organizations, reliance by the Company on sales entities which it
does not control, greater difficulty in maintaining direct client contact,
political and economic conditions in various jurisdictions, tariffs and other
trade barriers, longer accounts receivable collection cycles, difficulties in
protecting intellectual property rights in international jurisdictions, and
potentially adverse tax consequences. There can be no assurance that such
factors will not have a material adverse effect on the Company's business,
financial condition, and results of operations.
    
 
POTENTIAL EFFECT OF ANTI-TAKEOVER PROVISIONS
 
   
     The Company's Board of Directors has the authority, without action by the
Company's stockholders, to fix the rights and preferences of and to issue shares
of the Company's Preferred Stock, which may have the effect of delaying,
deterring, or preventing a change in control of the Company. The Company has
also imposed various procedural and other requirements that could make it more
difficult for stockholders to effect certain corporate actions. In addition, the
classification of the Board of Directors of the Company could have the effect of
delaying, deterring, or preventing a change in control of the Company. See
"Description of Capital Stock".
    
 
NO PRIOR PUBLIC MARKET
 
     Before this offering, there was no public market for the Common Stock, and
there can be no assurance that an active trading market will develop or be
sustained. The initial public offering price will be determined by negotiation
between the Company and the representatives of the Underwriters based on several
factors, including prevailing market conditions and recent operating results of
the Company, and may not be indicative of the market price of the Common Stock
after this offering. See "Underwriting".
 
SHARES ELIGIBLE FOR FUTURE SALE
 
     Sales of Common Stock in the public market after this offering could
adversely affect the market price of the Common Stock. The 2,000,000 shares
offered hereby will be freely tradeable in the open market. The remaining
6,000,000 shares, all of which Mr. Colony owns, are subject to a 180-day lock-up
agreement with the representatives of the Underwriters. Following the expiration
or earlier termination of the lock-up agreement, these shares will be eligible
for sale in the open market
 
                                        7
<PAGE>   9
 
   
pursuant to Rule 144 under the Securities Act of 1933, as amended (the
"Securities Act"). Upon completion of this offering, options to purchase 157,376
shares of Common Stock will be immediately exercisable, 106,595 of which shares
are subject to 180-day lock-up agreements with the representatives of the
Underwriters. The Company intends to register an aggregate of 200,000 shares of
Common Stock reserved for issuance under its employee stock purchase plan upon
consummation of this offering, which shares will not be issuable until June
1997. In addition, the Company intends to register an additional 2,900,000
shares of Common Stock reserved for issuance under its stock option plans 90
days after completion of this offering. See "Management -- Stock Plans" and
"Description of Capital Stock -- Shares Eligible for Future Sale".
    
 
ABSENCE OF DIVIDENDS
 
   
     The Company does not anticipate paying any cash dividends on the Common
Stock in the foreseeable future other than distributions to the Company's sole
stockholder in connection with the termination of the Company's S corporation
election. See "Termination of S Corporation Election and S Corporation
Distribution" and "Dividend Policy".
    
 
DILUTION
 
   
     Purchasers of the Common Stock offered hereby will suffer an immediate
dilution of $10.85 per share in the net tangible book value per share of the
Common Stock from the assumed initial public offering price. To the extent that
outstanding options to purchase Common Stock are exercised, there will be
further dilution. See "Dilution".
    
 
                                        8
<PAGE>   10
 
                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of the 2,000,000 shares of
Common Stock offered by the Company hereby (at an assumed initial public
offering price of $14.00 per share and net of estimated underwriting discount
and offering expenses) are estimated to be approximately $25,090,000
($28,996,000 if the Underwriters' over-allotment option is exercised in full).
The Company expects to use the net proceeds of this offering for working capital
and general corporate purposes, including possible acquisitions. The Company
currently has no commitments or agreements with respect to any specific
acquisition. Pending such uses, the Company intends to invest the net proceeds
primarily in short- and intermediate-term interest-bearing obligations of
investment grade.
 
                     TERMINATION OF S CORPORATION ELECTION
                         AND S CORPORATION DISTRIBUTION
 
   
     The Company has operated as an S corporation since January 1, 1987. As a
result of its S corporation election, the income of the Company has been taxed,
for federal and state income tax purposes, directly to the sole stockholder of
the Company, except for certain state income taxes imposed at the corporate
level. Upon the completion of this offering, the Company will terminate its S
corporation election and will be subject to federal and state income taxes at
prevailing corporate rates. Termination of this election will result in a net
deferred tax liability being recorded as a charge to operations during the
quarter in which this offering is completed. This deferred tax liability is
approximately $500,000 as of September 30, 1996.
    
 
     In addition, the Company will declare a distribution to its current
stockholder in an amount equal to the Company's undistributed S corporation
earnings. This distribution will be paid out of the Company's cash balances and
proceeds from the sale of marketable securities. See "Dividend Policy" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources". The Company and Mr. Colony also
intend to enter into a Tax Indemnification Agreement. See "Certain
Transactions".
 
                                DIVIDEND POLICY
 
   
     The Company paid cash dividends of $1,750,000, $1,121,342, and $169,893 to
Mr. Colony, the sole stockholder of the Company, in the years ended December 31,
1994 and 1995 and the nine months ended September 30, 1996, respectively. In
addition, the Company will make a distribution to Mr. Colony equal to the
Company's undistributed S corporation earnings through the termination of the
Company's S corporation election. This distribution is estimated to be
$3,600,000 based on earnings through September 30, 1996. This estimate does not
include the amount to be distributed for S corporation earnings from October 1,
1996 through the termination of the Company's S corporation election. The
Company anticipates that following completion of this offering and the
distribution of S corporation earnings to the Company's sole stockholder, future
earnings, if any, will be retained for the development of its business, and the
Company does not anticipate paying any cash dividends on the Common Stock in the
foreseeable future. See "Termination of S Corporation Election and S Corporation
Distribution" and "Management's Discussion and Analysis of Financial Condition
and Results of Operations -- Liquidity and Capital Resources".

                                    DILUTION
 
<TABLE>
   
     The pro forma net tangible book value of the Company as of September 30,
1996 was approximately $(81,000), or $(0.01) per share of common stock. Pro
forma net tangible book value per share of common stock is determined by
dividing the Company's tangible net worth (tangible assets less liabilities) by
the number of shares of Common Stock outstanding after giving effect to the (i)
distribution of previously undistributed S corporation earnings taxed or taxable
to the Company's sole stockholder of approximately $3,600,000 through September
30, 1996, and (ii) termination of the Company's S corporation election and the
recognition of a deferred income tax liability of approximately $500,000 as of
September 30, 1996, both to occur upon completion of this offering, but not
giving effect to the distribution to be made to the sole stockholder upon
completion of this offering in an amount equal to the Company's undistributed S
corporation earnings from October 1, 1996 through the date of termination of the
Company's S corporation election. After giving effect to the sale of 2,000,000
shares of Common Stock at an assumed initial public offering price of $14.00 per
share (less estimated underwriting discount and offering expenses) resulting in
estimated net proceeds of $25,090,000, the pro forma net tangible book value of
the Company as of September 30, 1996 would have been approximately $25,232,000,
or $3.15 per share. This represents an immediate increase of $3.16 per share to
the existing stockholder and an immediate dilution of $10.85 per share to new
investors. The following table illustrates this per share dilution:

(1) The Company has elected to be taxed, since January 1, 1987, under subchapter
    S of the Code, whereby the sole stockholder is liable for federal and state
    income taxes on the Company's taxable income. Upon the completion of this
    offering, the Company will terminate its S corporation election and will be
    subject to corporate-level federal and state income taxes. Accordingly, the
    pro forma income tax adjustments represent the income taxes that would have
    been recorded if the Company had been a C corporation for the periods
    presented. See Note 3 of Notes to Financial Statements.
 
   
(2) Pro forma net income per common share is computed by dividing pro forma net
    income by the weighted average number of shares of common stock and common
    stock equivalents outstanding during the period. See Note 1 of Notes to
    Financial Statements.
    
 
   
(3) Pro forma to give effect to the (i) distribution of previously undistributed
    S corporation earnings taxed or taxable to the Company's sole stockholder of
    approximately $3,600,000 through September 30, 1996, and (ii) termination of
    the Company's S corporation election and the recognition of a deferred
    income tax liability of approximately $500,000 as of September 30, 1996. See
    Notes 1 and 3 of Notes to Financial Statements.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS
 
OVERVIEW
 
   
     Forrester has experienced year-to-year revenue growth every year since its
inception in 1983. Over the last five years, the Company's revenues have
increased to $14.6 million in 1995 from $3.0 million in 1991. The Company's
revenues were $16.4 million in the first nine months of 1996. Forrester
attributes this growth to the Company's continuing reputation for quality
research and timely, accurate analysis of technology industry developments; the
introduction of new products and services; and the expansion of the Company's
sales and marketing organization. In addition, the Company believes the speed of
technology change and the increasingly participatory nature of technology
decisions have led to a growing market need for independent research and
analysis on the impact of technology on large enterprises, consumers, and
society.
    
 
   
     Revenues from core research also increased over the last five years, to
$10.1 million in 1995 from $1.6 million in 1991, and increased as a percentage
of total revenues to 70% in 1995 from 55% in 1991. Revenues from core research
were $12.6 million for the first nine months of 1996, or 77% of total revenues.
Forrester attributes this growth to, in addition to the factors cited above, an
increase in total Strategy Research Services offered -- from three in 1991 to
four in 1994, to six in 1995, and to a total of 10 Strategy Research Services as
of September 30, 1996.
    
 
     Memberships to Forrester's Strategy Research Services are renewable
contracts, typically annual and payable in advance. Accordingly, a substantial
portion of the Company's billings are initially recorded as deferred revenue and
recognized pro rata on a monthly basis over the contract period. The Company's
other revenues are derived from advisory services rendered pursuant to
Forrester's Partners Program and Strategy Review Program, and from the Forrester
Technology Management Forum (the "Forum"). The Company's advisory service
clients purchase such services in conjunction with the purchase of core research
memberships to Strategy Research Services, and the contracts for such purchases
are also generally payable in advance. Billings attributable to advisory
services are initially recorded as deferred revenues and recognized as revenue
when performed. Similarly, Forum billings are initially recorded as deferred
revenues and are recognized upon completion of the event.
 
     The Company's 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 production and delivery of the Company's
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, and sales commissions, which are
deferred when paid and expensed as the related revenue is recognized. General
and administrative expenses include the costs of the finance, operations, and
corporate IT groups, and other administrative functions of the Company.
 
   
     The Company has had income from operations in each of the last five years
from 1991 through 1995 and in the first nine months of 1996. Income from
operations rose 321% to $1.8 million in 1995 from $423,665 in 1991. Income from
operations was $2.2 million for the nine-month period ended September 30, 1996.
    
 
   
     The Company has elected to be taxed, since January 1, 1987, under
subchapter S of the Code whereby the sole stockholder is liable for individual
federal and certain state income taxes on the Company's taxable income. As such,
the Company has not paid federal income taxes and paid reduced state income
taxes. Upon completion of this offering, the Company will terminate its S
corporation election and will be subject to corporate-level federal and state
income taxes. Termination of this election will result in a deferred income tax
liability being recorded as a charge to operations during the quarter in which
this offering is completed. This deferred tax liability is approximately
$500,000 as of September 30, 1996. The combination of the state income tax
provision and the pro forma income tax adjustment in the Company's historical
financial statements
    
 
                                       14
<PAGE>   16
 
reflects the federal and state income taxes which would have been recorded if
the Company had been treated as a C corporation during the periods presented.
The Company has calculated these amounts based upon an estimated effective tax
rate for the respective periods.
 
   
     The Company believes that the "agreement value" of contracts to purchase
core research and advisory services provides a significant measure of the
Company's business volume. Forrester calculates agreement value as the
annualized fees payable under all core research and advisory services contracts
in effect at a given point in time, without regard to the remaining duration of
such contracts. Agreement value increased 74% to $17.8 million at December 31,
1995 from $10.2 million at December 31, 1994. At September 30, 1996 agreement
value was $25.9 million. The Company's experience is that a substantial portion
of client companies renew expiring contracts for an equal or higher level of
total core research and advisory service fees each year. Approximately 71% and
72% of Forrester's client companies with memberships expiring during 1995 and
the first nine months of 1996, respectively, renewed one or more memberships for
the Company's products and services, although these renewal rates are not
necessarily indicative of the rate of future retention of the Company's revenue
base. The number of client companies increased to more than 860 at September 30,
1996 from 799 at December 31, 1995, and no single client company accounted for
over 4% of the Company's revenue in 1995 or over 3% of the Company's revenue in
the nine months ended September 30, 1996.

     REVENUES.  Total revenues increased 80% to $16.4 million in the nine months
ended September 30, 1996 from $9.1 million in the corresponding period of 1995.
Revenues from core research increased 79% to $12.6 million in the nine months
ended September 30, 1996 from $7.0 million in the corresponding period in 1995.
The increases in total revenues and revenues from core research were primarily
attributable to an increase in the number of clients, the introduction of new
Strategy Research Services, and continued expansion and increased productivity
of the Company's sales force.

     Advisory services and other revenues increased 82% to $3.8 million in the
nine months ended September 30, 1996 from $2.1 million in the nine months ended
September 30, 1995. This increase was primarily attributable to demand for the
Partners and Strategy Review Programs.
    
 
   
     Revenues attributable to customers outside the United States increased 102%
to $3.4 million in the nine months ended September 30, 1996 from $1.7 million in
the nine months ended September 30, 1995, and also increased as a percentage of
total revenues to 21% for the nine months ended September 30, 1996 from 18% for
the nine months ended September 30, 1995. The increase was due primarily to the
addition of direct international sales personnel. The Company invoices its
international clients in U.S. dollars.
    
 
   
     Agreement value grew to $25.9 million at September 30, 1996 from $13.7
million at September 30, 1995. No single client company accounted for more than
2% of agreement value or 3% of revenues for the nine months ended September 30,
1996.
    
 
   
     COST OF SERVICES AND FULFILLMENT.  Cost of services and fulfillment
decreased as a percentage of total revenues to 36% in the nine months ended
September 30, 1996 from 39% in the nine months ended September 30, 1995. These
costs increased 67% to $5.9 million in the nine months ended September 30, 1996
from $3.5 million in the nine months ended September 30, 1995. The expense
increase in this period was principally due to increased analyst staffing for
new Strategy Research Services and related compensation expense.
    
 
   
     SELLING AND MARKETING.  Selling and marketing expenses decreased as a
percentage of total revenues to 38% in the nine months ended September 30, 1996
from 41% in the nine months ended September 30, 1995. These expenses increased
67% to $6.2 million in the nine months ended September 30, 1996 from $3.7
million in the nine months ended September 30, 1995. The increase in expense was
principally due to the addition of direct salespersons and increased sales
commission expense associated with increased revenues. The decrease as a
percentage of total revenues was principally due to increased productivity of
the Company's direct sales force.
    
 
   
     GENERAL AND ADMINISTRATIVE.  General and administrative expenses increased
as a percentage of total revenues to 11% in the nine months ended September 30,
1996 from 10% in the nine months ended September 30, 1995. These expenses
increased 93% to $1.7 million in the nine months ended September 30, 1996 from
$887,037 in the nine months ended September 30, 1995. The increase in expenses
was principally due to staffing increases in operations and IT and higher costs
associated with the Company's new Cambridge headquarters.
    
 
   
     DEPRECIATION AND AMORTIZATION.  Depreciation and amortization expense
increased 73% to $359,531 in the nine months ended September 30, 1996 from
$207,347 in the nine months ended September 30, 1995. The increase in this
expense was principally due to purchases of computer equipment, software, and
office furnishings to support business growth, and the Company's move to its new
Cambridge headquarters and expansion thereof.
    
 
   
     INTEREST INCOME.  Interest income increased to $353,915 in the nine months
ended September 30, 1996 from $266,252 in the nine months ended September 30,
1995 due to an increase in the Company's cash balances resulting from positive
cash flows from operations.
    
 
  YEARS ENDED DECEMBER 31, 1995, 1994, AND 1993
 
   
     REVENUES.  Total revenues increased 50% to $14.6 million in 1995 from $9.7
million in 1994, and 33% from $7.3 million in 1993. Revenues from core research
increased 59% to $10.1 million in 1995 from $6.4 million in 1994, and 36% from
$4.7 million in 1993. The increases in total revenues and revenues from core
research were primarily attributable to an increase in the number of clients,
the introduction of new Strategy Research Services, continued expansion and
increased productivity of the Company's sales force, and growing market
acceptance of the Company's products. The Company introduced two new Strategy
Research Services in 1995, one new Strategy Research Service in 1994, and did
not start any new Strategy Research Services in 1993.
    
 
     Advisory services and other revenues increased 33% to $4.4 million in 1995
from $3.3 million in 1994, and 28% from $2.6 million in 1993. The increase in
advisory services and other revenues was
 
                                       16
<PAGE>   18
 
   
primarily attributable to demand for the Company's advisory services. The
decrease of these revenues as a percentage of total revenues to 30% in 1995 from
34% in 1994 and 36% in 1993 reflects the results of the Company's strategy to
expand sales of its core research. See "Business -- Strategy".
    
 
     Revenues attributable to sales to customers outside the United States
increased 61% to $2.6 million in 1995 from $1.6 million in 1994, and 43% from
$1.1 million in 1993. International sales represented 18%, 16%, and 15% of total
revenue for 1995, 1994, and 1993, respectively. The increase was due primarily
to the Company's creation and growth of a direct international sales force from
one employee in 1993 to eight employees at December 31, 1995.
 
     Agreement value grew 74% to $17.8 million at December 31, 1995 from $10.2
million at December 31, 1994, and 75% from $5.8 million at December 31, 1993.
 
   
     COST OF SERVICES AND FULFILLMENT.  Cost of services and fulfillment
increased as a percentage of total revenues to 37% in 1995 from 35% in 1994 and
33% in 1993. These costs increased 60% to $5.5 million in 1995 from $3.4 million
in 1994, and 42% from $2.4 million in 1993. These increases were principally due
to investment in new Strategy Research Services and resultant increased analyst
staffing and related compensation expense.
    
 
     SELLING AND MARKETING.  Selling and marketing expenses increased as a
percentage of total revenues to 39% in 1995 from 37% in 1994 and 1993. These
expenses increased 57% to $5.6 million in 1995 from $3.6 million in 1994, and
33% from $2.7 million in 1993. The increase in expenses was principally due to
the addition of direct salespersons and marketing personnel and increased sales
commissions resulting from increased revenues.
 
   
     GENERAL AND ADMINISTRATIVE.  General and administrative expenses decreased
as a percentage of total revenues to 9% in 1995 from 10% in 1994 and 16% in
1993. These expenses increased 33% to $1.4 million in 1995 from $1.0 million in
1994, and decreased 9% from $1.1 million in 1993. The increase in expenses from
1994 to 1995 was principally due to staffing increases in operations and IT,
higher costs associated with the Company's new Cambridge headquarters, and
investment in the Company's internal IT systems.
    
 
   
     DEPRECIATION AND AMORTIZATION.  Depreciation and amortization expense
increased 91% to $287,705 in 1995 from $150,067 in 1994, and 43% from $105,120
in 1993. The increase in this expense was principally due to purchases of
computer equipment, software, and office furnishings to support business growth
and the Company's move to its new Cambridge headquarters and expansion thereof.
    
 
   
     INTEREST INCOME.  Interest income increased 171% to $339,569 in 1995 from
$125,115 in 1994, and 58% from $79,343 in 1993. This increase resulted primarily
from an increase in the Company's cash balances resulting from positive cash
flows from operations.

     Revenues generally increased each quarter during the seven quarters ended
September 30, 1996, reflecting the overall growth in the Company's business.
Historically, total revenues in the fourth quarter have reflected the
significant positive contribution of revenues attributable to the Forrester
Forum. As a result, the Company has typically experienced a decline in total
revenues from the quarter ended December 31 to the quarter ended March 31. In
addition, cost of services and fulfillment and sales and marketing expense has
typically decreased as a percentage of revenues during the fourth quarter. Sales
and marketing expenses increased as a percentage of revenues during the quarter
ended June 30, 1995 due to additional costs related to new collateral material
printed in connection with the Company's move into its new Cambridge offices.
General and administrative expenses increased as a percentage of revenues during
the quarter ended March 31, 1996 compared to the quarter ended December 31, 1996
due to increased hiring of operations personnel and the increased revenues
during the quarter ended December 31, 1995 attributable to the Forum. The
Company's quarterly operating results have fluctuated in the past and may
continue to fluctuate in the future.
    
 
LIQUIDITY AND CAPITAL RESOURCES
 
   
     The Company has financed its operations to date through funds generated
from operations. Memberships for core research, which constituted approximately
77% of the Company's revenues for the nine months ended September 30, 1996, are
annually renewable and are generally payable in advance. These up-front payment
terms together with historical year-to-year revenue growth have allowed the
Company to generate positive cash flows each year since 1984, one year after its
inception in 1983. The Company generated $4.6 million in cash from operating
activities during 1995, $3.7 million during 1994, and $1.3 million during 1993.
In the nine months ended September 30, 1996, the Company generated $4.8 million
in cash from operating activities.
    
 
   
     In 1995, the Company used $5.2 million of cash in investing activities,
consisting of $751,850 for the purchase of property and equipment and $4.5
million for net purchases of marketable securities. The Company regularly
invests excess funds in short- and intermediate-term interest-bearing
obligations of investment grade. In 1995, the Company used $1.1 million in
financing activities, consisting solely of a distribution to the stockholder
primarily to pay income taxes on the Company's net income. See "Termination of S
Corporation Election and S Corporation Distribution" and "Dividend Policy"
above.
    
 
   
     In the nine months ended September 30, 1996, the Company used $4.4 million
of cash in investing activities. The primary uses were the purchase of $1.5
million of property and equipment and the net purchase of $2.9 million of
marketable securities.
    
 
   
     As of September 30, 1996, the Company had cash and cash equivalents of $1.3
million and $9.6 million in marketable securities. This amount will be reduced
by a distribution to the sole stockholder of the Company after completion of
this offering as described in "Termination of S Corporation Election and S
Corporation Distribution". The Company does not have a line of credit and does
not anticipate the need for one in the foreseeable future. The Company currently
has no material capital commitments and does not foresee that capital
expenditures will increase substantially during the next two years. The Company
believes that its current cash balance, marketable securities, and cash flows
from operations, together with the net proceeds from the offering, will satisfy
working capital, financing activities, and capital expenditure requirements for
at least the next two years.
    
 
   
     The Company will declare a distribution to its current stockholder in an
amount equal to the Company's undistributed S corporation earnings of
approximately $3,600,000 through September 30, 1996. The estimated distribution
through September 30, 1996 does not include the amount to be distributed for S
corporation earnings from October 1, 1996 through termination of the Company's S
corporation election. These distributions will be paid out of the Company's cash
balances and proceeds from the sale of marketable securities.

                                    BUSINESS
 
   
     Forrester is a leading independent research firm offering products and
services that help its clients assess the effect of technology on their
businesses. The Company provides analysis and insight into a broad range of
technology areas such as computing, software, networking, the Internet, and
telecommunications, and projects how technology trends will impact businesses,
consumers, and society. Forrester's clients, which include senior management,
business strategists, and IT professionals within large enterprises, use
Forrester's prescriptive research to understand and benefit from current
developments in technology and as support for their development and
implementation decisions.
    
 
     Forrester offers its clients annual memberships to any of its 10 research
services ("Strategy Research Services"). Each Strategy Research Service focuses
on a particular area of technology and explores business issues relevant to
clients' decision-making. These issues include the impact that the application
of technology may have on financial results, investment priorities,
organizational effectiveness, and staffing requirements. Forrester also provides
advisory services to a limited number of clients to help them explore in greater
detail the topics covered by the core research.
 
   
     Forrester targets its products and services to both large enterprises and
technology vendors. As of September 30, 1996, Forrester's research was delivered
to more than 860 client companies. No single client company accounted for more
than 3% of the Company's revenues during the nine-month period ended September
30, 1996. Approximately 72% of Forrester's client companies with memberships
expiring during the nine-month period ended September 30, 1996 renewed one or
more memberships for the Company's products and services.
    
 
INDUSTRY BACKGROUND
 
     Businesses increasingly depend on technology for competitive advantage and
success. Technology is being used as a strategic tool to develop innovative
products, services, and distribution channels, as well as to create more
efficient internal business processes. Decisions about how to deploy networks,
software, and other systems are increasingly participatory, with
line-of-business managers, marketing executives, and corporate leaders joining
IT professionals in the technology review and decision-making process. Together,
these individuals must develop a coherent strategy that leverages innovative
systems to reach new markets, gain competitive advantage, and develop high
customer service and loyalty levels. Developing such a strategy is difficult,
however, as the rate of technology change accelerates. Increased complexity and
the proliferation of vendors and solutions have increased the challenges in
anticipating and understanding emerging technologies.
 
     The strategic use of technology, the widening scope of decision-making, the
speed of change, and the complexity of decisions make it difficult for
organizations to efficiently generate research and analysis on their own. Costly
incremental resources -- time and expertise -- are required for successful
analysis and implementation of technology. Poor decisions can be costly and
detrimental to an organization's competitive position. Consequently, demand is
growing for external sources of expertise that provide independent,
vendor-neutral business advice on how to benefit from technology change.
Research firms that provide tactical product assessment or customized consulting
are often too narrow in their perspective to satisfy this demand. Business
leaders as well as technology users require comprehensive research that can
anticipate, assess, and interpret major trends. Forrester believes there is a
growing need for thematic, prescriptive analysis of technology that appeals to
senior management, business strategists, and IT professionals, and helps
organizations improve their strategic planning processes, leverage technology
change, and gain competitive advantage.

THE FORRESTER SOLUTION
 
     Forrester addresses the growing demand for thematic, prescriptive analysis
of technology by providing business-focused research to senior management,
business strategists, and IT professionals. The Company's research methodology
analyzes complex technology issues and delivers prescriptive analysis and advice
through each of its 10 Strategy Research Services. This research helps large
enterprises make informed decisions that positively affect competitive strategy
and business performance, reduce risk, and manage cost. Although Forrester's
research is user-focused, IT vendors also use Forrester's research for
marketing, product positioning, and market planning.
 
     Forrester differentiates its products and services from those offered by
other research firms by:
 
          ADDRESSING NEEDS OF BUSINESS EXECUTIVES.  Forrester's core research
     and advisory services blend analysis of technology with related business
     issues to enable senior management to better use technology for competitive
     advantage. Unlike narrowly focused, tactically based research that assesses
     products and components, Forrester's research provides a strategic view of
     the impact of technology on long-term business plans.
 
          DELIVERING VALUABLE, STAND-ALONE WRITTEN RESEARCH.  Forrester's
     research distills the abundance of information, activities, and
     developments in the IT industry into a concise, easy-to-read guide for
     decision-making. In contrast to research that requires interactive
     consulting support, Forrester's research is designed to provide valuable,
     prescriptive analysis that stands on its own without requiring ongoing
     analyst interaction.
 
          TAKING A STAND ON DIFFICULT TECHNOLOGY ISSUES.  Forrester's research
     and analysts challenge conventional viewpoints; the Company does not expect
     clients to agree with every prediction or conclusion presented. However,
     the Company does believe that strong opinions and recommendations will
     enable clients to more thoroughly consider the use of technology to gain
     competitive advantage. Forrester, unlike many other research firms,
     provides concrete, actionable business advice.
 
          PROVIDING A BROAD VIEW OF TECHNOLOGY CHANGE.  Forrester's research
     approach provides an integrated, cross-disciplinary view of technologies
     and their impact throughout organizations and industries. The Company's
     cross-service collaboration ensures that a coherent, thematic analysis is
     consistently delivered to clients. Forrester's broad perspective can be
     contrasted with narrowly defined, specifically tailored technology
     assessments.
 
          FOCUSING ON EMERGING TECHNOLOGIES IN CONSUMER AND BUSINESS
     MARKETS.  Forrester's research methodology is designed to identify
     fundamental shifts in technology before these changes appear on the
     horizons of most users, vendors, and other research firms. Forrester's
     interview-based research approach combines input from early adopters of new
     technologies, vendors, and consumers to gauge the likelihood of a
     technology's success and its potential impact on various markets.
 
STRATEGY
 
     Forrester seeks to capitalize on the growing demand for technology
research, analysis, and advice. To achieve this goal, Forrester has adopted the
following strategies:
 
          LEVERAGE CORE RESEARCH.  By focusing on sales of its stand-alone core
     research, the Company can deliver value to its clients and can increase its
     revenues without having to provide ongoing and direct analyst support. In
     addition, Forrester's current and developing electronic delivery options
     make it easier to disseminate research within an organization while
     providing greater ease of use, including the ability to search, customize,
     and sort information according to individual preferences. Finally, the
     Company intends to continue to introduce new Strategy Research Services and
     to provide advisory services that build upon the analysis and
     recommendations set forth in the core research to enhance sales of that
     core research.
 
                                       21
<PAGE>   23
 
   
          EXPAND CLIENT BASE AND PENETRATE EXISTING ACCOUNTS.  The Company
     believes that its current offerings of products and services, and
     anticipated new products and services, can continue to be successfully
     marketed and sold to new client companies, as well as to new organizations
     within existing client companies. Forrester currently targets senior
     management, business strategists, and IT professionals within Fortune 1,000
     companies. The Company seeks to expand its international audience by
     targeting select geographic markets. The Company also aims to increase the
     number of Strategy Research Services that each client purchases through
     increased marketing of new and current products and services.
    
 
          IDENTIFY AND DEFINE NEW TECHNOLOGY MARKETS.  Forrester seeks to
     position itself ahead of other research firms by delivering strategic
     research and analysis on new and emerging technologies. Forrester believes
     its methodology and culture allow it to focus on areas of technology change
     and enable it to expand its product and service offerings to address new
     technology issues.
 
          ATTRACT AND RETAIN HIGH-QUALITY RESEARCH PROFESSIONALS.  The knowledge
     and experience of Forrester's analysts are critical elements of the
     Company's ability to provide high-quality products and services. The
     Company seeks to attract, develop, and retain outstanding research
     professionals by providing a creative corporate environment and culture, a
     competitive compensation structure, training and mentoring programs for
     individual development, and recognition and rewards for excellent
     individual and team performance.
 
          EXPAND AND LEVERAGE SALES FORCE.  The Company is expanding its current
     direct sales force and is seeking to increase the average sales volume per
     sales representative. The Company believes that this increase can be
     achieved as the average tenure of the Company's sales representatives
     lengthens and marketing initiatives shorten the sales cycle. Initiatives
     include the improvement of existing and the development of new methods for
     obtaining highly qualified sales leads, targeted use of third-party
     telemarketing firms, and hosting of regional marketing events around the
     world.
 
PRODUCTS AND SERVICES
 
     Forrester's principal products are annually renewable memberships to 10
Strategy Research Services in three main research areas: Corporate IT, New
Media, and Strategic Management. Corporate IT Research services analyze how
technology change impacts IT's infrastructure, tactics, and mission; New Media
Research services provide insight into how companies can leverage emerging
technology to deliver content and services to consumers; and Strategic
Management Research assists senior executives in understanding the long-term
implications of technology change on organizational and business strategies.
Each Strategy Research Service delivers monthly Reports and biweekly Briefs,
except the Leadership Strategies service which delivers Reports on a bimonthly
basis and Executive Takes on a biweekly basis. Additionally, Forrester provides
advisory services to select clients through the Partners Program and Strategy
Review Program. The Company holds one major event each year, the Forrester
Technology Management Forum, a two-day conference devoted to leading technology
issues.
 
  STRATEGY RESEARCH SERVICES
 
     The Company's Strategy Research Services provide ongoing research and
analysis on the developments, information, and activities in the technology
industry. Each service is staffed by a team of research analysts and associates
with substantial experience in the technology area covered by that service. The
services employ a consistent research methodology to analyze technology issues,
address related business issues, and offer recommendations and action plans.
While each service addresses a specific technology area, collectively they
present complementary, consistent research themes and provide comprehensive
coverage of relevant technology issues faced by the Company's clients.
Businesses are able to supplement and extend internal resources with current,
thorough, and focused analysis and recommendations. In addition, technology
vendors are able to augment and test competitive, new product, marketing, and
sales plans against Forrester's independent analysis and advice.

     Each client that purchases a membership to a Strategy Research Service
receives the following written materials:
 
          FORRESTER REPORTS are created monthly by the services in Corporate IT
     and New Media Research, and bimonthly by the Leadership Strategies service.
     These Reports deliver analysis on current technology issues in a concise
     format.
 
   
          FORRESTER BRIEFS AND TAKES offer timely analysis on industry events,
     issues, technology, or other specific research topics. Corporate IT and New
     Media clients receive 24 Briefs per year, and Leadership Strategies clients
     receive 26 Executive Takes per year.
    
 
          JOURNAL ENTRIES are presented at the end of every Forrester Report and
     offer Forrester's inside perspective on current events in the industry.
 
          In addition to printed reports, Strategy Research Service core
     research deliverables are available in the following electronic delivery
     formats:
 
          FORRESTER INTERNET gives clients access to a full archive of
     Forrester's research from 1993 to the present via the World Wide Web.
     Extensive search capabilities and end user customization allow clients to
     tailor document viewing to their particular needs.
 
          FORRESTER INTRANET delivers the same research archive as Forrester
     Internet, can be purchased with or without a search engine, and is
     compatible with any client's Intranet environment.
 
          FORRESTER RESEARCH FOR LOTUS NOTES USERS provides access to
     Forrester's full research archive from 1993 to the present via replication
     to Forrester's Lotus Notes server. Documents can be viewed and sorted by
     Strategy Research Service, analyst, technology, product, company, people,
     or date.
 
  ADVISORY SERVICES AND EVENTS
 
   
     Forrester provides advisory services to a limited number of clients through
its Partners Program and Strategy Review Program. These programs leverage
Forrester's research expertise to address clients' long-term planning issues and
align Forrester's core research and insight with specific business goals. As of
September 30, 1996, 68 client companies were members of the Partners Program and
196 client companies were members of the Strategy Review Program. In addition to
core research, each client purchasing a membership to the Partners Program and
Strategy Review Program receives the following deliverables, respectively:
    
 
          THE PARTNERS PROGRAM provides clients with a proactive relationship
     with Forrester analysts to address long-range planning, technology
     decision-making, and strategic management best practices. The base program
     includes a series of one-day meetings and conference calls with Forrester
     analysts.
 
          THE STRATEGY REVIEW PROGRAM gives clients access to Forrester analysts
     in a series of quarterly two-hour conference calls or meetings in order to
     apply the research to business strategies.
 
     The Company also hosts the Forrester Forum each year. The Forum brings
together more than 500 senior executives for a two-day conference to network
with their peers and hear major figures from the technology industry and leaders
from other business sectors discuss the impact of technology change on business.
 
  PRICING
 
   
     The prices for Forrester's core research are a function of the number of
services purchased, the number of research recipients within the client
organization, and the delivery format (i.e., printed or electronic). The average
contract for annual memberships sold to Forrester clients for core
    
 
                                       24
<PAGE>   26
 
   
research, excluding annual memberships for core research in connection with
Forrester's Partners and Strategy Review Programs, for the year ended December
31, 1995 was approximately $10,200 and for the nine months ended September 30,
1996 was approximately $13,600. The prices for Forrester's Partners and Strategy
Review Programs are also a function of the number of services purchased, the
number of research recipients within the client organization, delivery format,
and amount and type of advisory services. All Partners Program and Strategy
Review Program memberships sold include core research. The average contract for
annual memberships sold to Forrester clients for the Partners Program for the
year ended December 31, 1995 was approximately $65,700 and for the nine months
ended September 30, 1996 was approximately $86,600. The average contract price
of annual memberships sold to Forrester clients for the Strategy Review Program,
for the year ended December 31, 1995 was approximately $33,300 and for the nine
months ended September 30, 1996 was approximately $35,700.
    
 
   
     Forrester believes that the agreement value of contracts to purchase core
research and advisory services provides a significant measure of the Company's
business volume. Forrester calculates agreement value as the annualized fees
payable under all core research and advisory services contracts in effect at a
given point in time, without regard to the remaining duration of the contracts.
Agreement value at December 31, 1994 was $10.2 million and grew to $17.8 million
at December 31, 1995. At September 30, 1996, agreement value was $25.9 million.
    
 
RESEARCH AND ANALYSIS
 
     Forrester employs a structured and consistent research methodology across
the Company's 10 Strategy Research Services. Each service is managed by a
service director who is responsible for implementing the Company's research
methodology and maintaining research quality in the service's particular
technology coverage area. Forrester's methodology enables the Company to
identify and analyze emerging technology trends, markets, and audiences, and
ensures consistent research quality and recommendations across all services. The
Company's research is thematic in approach: Forrester Reports are composed
around major technology trends, not isolated technology review and assessment.
Research themes apply throughout different research Reports, within services,
and across research services.
 
     Forrester's research process subjects initial ideas to research, analysis,
and rigorous validation, and produces conclusions, predictions, and
recommendations. Forrester employs several different primary research methods:
confidential interviews with early adopters of new technology, technology
vendors, consumers, and users and vendors in related technology areas; regular
briefings with vendors to review current positions and future directions; and
input from clients and third parties gathered during advisory sessions.
 
     Reports begin with cross-service discussion sessions with analysts.
Cross-service testing of an idea continues throughout the Report process at
informal and weekly research meetings. At the final stage of the research
process, senior analysts meet to test the conclusions of each Report. Also, each
Report is reviewed by an analyst outside the research service as an additional
quality check and to ensure clarity and readability by all clients -- especially
those lacking strong technology backgrounds. All research is reviewed and graded
by Forrester's senior research directors.
 
     The knowledge and experience of Forrester's analysts are critical elements
of the Company's ability to provide high-quality research and analysis.
Forrester analysts average approximately 10 years of industry experience, with
varied backgrounds mirroring all facets of the industry -- vendor and user
marketing and development, entrepreneurs, financial services, and journalism.
The Forrester culture and compensation system foster a dedication to
high-quality research across all research services.
 
     All members of Forrester's research staff participate in the Company's
incentive compensation bonus plan. Each employee's performance against
individual and team goals determines an eligible bonus that is funded by the
Company's overall performance against key business objectives. Individual and
team goals include on-time delivery of high-quality research, core research
bookings,
 
                                       25
<PAGE>   27
 
and advisory services support to Partners and Strategy Review Program clients.
Senior analysts and research directors are eligible to receive equity awards
under the Company's stock plans.
 
SALES AND MARKETING
 
   
     Forrester has made a substantial investment in its direct sales force to
better serve clients and address additional markets. The Company's direct sales
force, comprised of 38 sales representatives as of September 30, 1996, consists
of business development managers who are responsible for maintaining and
leveraging the current client base by renewing and selling additional Strategy
Research Services to existing clients, corporate account managers who develop
new business in assigned territories, and regional sales directors who focus on
high-level client contact and service.
    
 
   
     Forrester sells its products and services through its headquarters in
Cambridge, Massachusetts, and a regional sales office in San Francisco.
Forrester also uses six local independent sales representatives to market and
sell its products and services internationally. These independent third-party
representatives cover the following territories: Australia, Brazil, France,
Japan, Spain, and South Africa.
    
 
     The Company has developed and will continue to implement products and
programs to support the sales representatives in their effort to differentiate
Forrester and define the value derived from the Company's research and analysis.
These products and programs include extensive worldwide press relations, direct
mail campaigns, telemarketing, and a worldwide events program. In addition, the
Company uses its Web site as a strategic tool to increase the quality and speed
of lead development for the sales force. All Forrester sales representatives
participate in the Company's annual commission and bonus plan. Commissions are
paid monthly based upon attainment of net bookings against established quotas;
quarterly bonuses are paid for exceeding quota levels.
 
   
     As of September 30, 1996, Forrester's research was delivered to over 860
client companies, including 57 of the 1996 Fortune 100 companies and 157 of the
1996 Fortune 500 companies. No single client company accounted for over 3% of
the Company's revenues for the nine months ended September 30, 1996.
    
 
COMPETITION
 
     Forrester believes that the principal competitive factors in its industry
include quality of research and analysis, timely delivery of information, the
ability to offer products that meet the changing needs of organizations for
research and analysis, independence from vendors, and customer service and
price. The Company believes it competes favorably with respect to each of these
factors. Additionally, the Company believes that its business-focused review of
emerging technologies and high-level, easy-to-read research format distinguish
it from its competitors.
 
     The Company competes in the market for technology research products and
services with other independent providers of similar services. Forrester's
principal direct competitor in IT research is Gartner Group, Inc., which has a
substantially longer operating history, is significantly larger, and has
considerably greater financial resources and market share than the Company.
Numerous other companies, including META Group, Inc., provide IT research and
analysis. In addition, the Company's indirect competitors include the internal
planning and marketing staffs of the Company's 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. The Company's indirect competitors could choose to compete
directly against the Company in the future. In addition, there are relatively
few barriers to entry into the Company's market and new competitors could
readily seek to compete against the Company in one or more market segments
addressed by the Company's Strategy Research Services. Increased competition
could adversely affect the Company's operating results through pricing pressure
and loss of market share. There can be no assurance that the Company will be
able to continue to compete successfully against existing or new competitors.

EMPLOYEES
 
     Forrester's culture emphasizes certain key values -- quality, cooperation,
and creativity -- that it believes are critical to its continued growth. To
encourage achievement of the Company's key values, the Company places great
emphasis on individual excellence, and employees at all levels of the
organization are encouraged to take initiative and lead individual projects that
enhance Forrester's effectiveness. Forrester regularly recognizes and rewards
excellent performance in all areas of the Company. The Company's balanced
emphasis on individual achievement and teamwork is reflected in its compensation
structure. Each employee's performance is measured against individual and team
goals that determine an eligible bonus funded by the Company's overall
performance against key business objectives. This structure gives employees a
vested interest in the Company's overall success and performance while still
promoting individual excellence.
 
   
     As of September 30, 1996, Forrester employed a total of 119 persons,
including 55 research staff, 44 sales and marketing personnel, and 20 operations
personnel. Of these employees, 118 are located at the Company's headquarters in
Cambridge, Massachusetts and one is located at another domestic facility. None
of the Company's employees is represented by a collective bargaining
arrangement, and the Company has experienced no work stoppages. The Company
believes that its relations with its employees are good.
    
 
   
     As of September 30, 1996, there were options to purchase 748,691 shares of
the Common Stock of the Company granted to employees under the Company's 1996
Amended and Restated Equity Incentive Plan. Upon completion of this offering,
options to purchase 149,376 shares of the Company's Common Stock held by
employees of the Company will become immediately exercisable.
    
 
     Forrester's continued growth depends in large part on its ability to
attract, retain, and motivate highly skilled research analysts, sales and
marketing personnel, and operations staff. Competition for highly skilled
personnel in the Company's market is intense, and many of the companies with
which Forrester directly competes for such personnel have substantially greater
financial and other resources than the Company. In addition, competition for
highly skilled personnel can be expected to become more intense as competition
in the Company's industry increases. Although the Company expects to continue to
attract sufficient numbers of highly skilled employees and to retain and
motivate its existing research analysts, sales and marketing personnel, and
operations staff for the foreseeable future, there can be no assurance that the
Company will be able to do so. The loss of any of the Company's senior
management personnel or any failure to attract, retain, and motivate a
sufficient number of qualified personnel would have a material adverse effect on
the Company's business, financial condition, and results of operations. The
Company has entered into non-competition agreements with each of its group
directors, service directors, senior analysts, and certain other employees which
provide that such persons will not compete with the Company for the one-year
period after the date of termination of employment with the Company.
 
FACILITIES
 
     The Company's headquarters are located in approximately 30,000 square feet
of office space in Cambridge, Massachusetts. This facility accommodates
research, marketing, sales, IT, and operations personnel. The initial lease term
of this facility expires in January 2001. The Company has the option to extend
this lease for up to two additional terms of five years each. The Company also
leases office space in San Francisco to support its sales functions. The Company
believes that its existing facilities are adequate for its current needs and
that additional facilities are available for lease to meet future needs.
 
   
LEGAL PROCEEDINGS
    
 
   
     The Company is not currently a party to any material legal proceedings.

operations of the Company with officers of the Company who are responsible for

filed a registration statement under the Securities Act covering the Common
Stock, an option to purchase 6,000 shares of the Company's Common Stock at an
exercise price of $13.00. Such options will vest in three equal installments
commencing on the date of completion of the initial public offering of the
Common Stock and on the first and second anniversaries of such date. See "Stock
Plans -- 1996 Stock Option Plan for Non-Employee Directors".

STOCK PLANS
 
  1996 EQUITY INCENTIVE PLAN
 
   
     The Company's Amended and Restated 1996 Equity Incentive Plan (the "Equity
Incentive Plan"), which was originally approved by the Board of Directors and
the sole stockholder of the Company in February 1996 and amended and restated in
September 1996, provides for grants of incentive stock options within the
meaning of Section 422 of the Code, non-qualified stock options, and restricted
and nonrestricted shares to employees and other persons who are important to the
success of the Company. As of September 30, 1996, a total of 2,750,000 shares of
Common Stock have been reserved for issuance under the Equity Incentive Plan,
subject to adjustment for stock splits and similar events, of which 2,001,309
remained available for future grants. The exercise price of all incentive stock
options granted under the Equity Incentive Plan must be at least equal to the
fair market value of the shares of Common Stock on the date of grant. The
exercise price of all non-
    
 
                                       30
<PAGE>   32
 
   
qualified options granted under the Equity Incentive Plan is determined by the
Compensation Committee of the Board of Directors. The Compensation Committee may
reduce the exercise price of any outstanding options. With respect to any
participant who owns stock possessing more than 10% of the voting power of all
classes of stock of the Company, the exercise price of any incentive stock
option granted must equal at least 110% of the fair market value on the grant
date and the maximum term of the option must not exceed five years. The term of
all other options granted under the Equity Incentive Plan may not exceed 10
years. Unless terminated sooner, the Equity Incentive Plan will terminate in
February 2006. The Board of Directors has authority to amend or terminate the
Equity Incentive Plan, provided no such action may impair the rights of the
holder of any outstanding options without the written consent of such holder.
    
 
  1996 EMPLOYEE STOCK PURCHASE PLAN
 
     The Company's 1996 Employee Stock Purchase Plan (the "Stock Purchase
Plan"), which was approved by the Board of Directors and by the sole stockholder
of the Company in September 1996, is intended to qualify under Section 423 of
the Code. A total of 200,000 shares of Common Stock has been reserved for
issuance under the Stock Purchase Plan. Purchases under the Stock Purchase Plan
will occur at the end of each option period. The first option period will
commence on the date of this Prospectus and will end on June 30, 1997.
Thereafter, each option period will be successive six-month purchase periods.
Employees are eligible to participate if they are regularly employed by the
Company for at least 30 hours per week.
 
     The Stock Purchase Plan permits eligible employees to purchase Common Stock
through payroll deductions that may not exceed 10% of an employee's base
compensation, including commissions, bonuses, and overtime, at a price equal to
85% of the fair market value of the Common Stock at the beginning or the end of
a purchase period, whichever is lower. Unless terminated sooner, the Stock
Purchase Plan will terminate 10 years from its effective date. The Board of
Directors has authority to amend or terminate the Stock Purchase Plan, provided
no such action may adversely affect the rights of any participant.
 
  1996 STOCK OPTION PLAN FOR NON-EMPLOYEE DIRECTORS
 
   
     The Director Option Plan was approved by the Board of Directors and by the
sole stockholder of the Company in September 1996. Pursuant to the Director
Option Plan, non-employee directors who have agreed to serve as a director of
the Company have each received, on the date that the Company first filed a
registration statement under the Securities Act covering the Common Stock, an
option to purchase 6,000 shares of the Company's Common Stock at an exercise
price of $13.00. Such options will vest in three equal installments commencing
on the date of completion of the initial public offering of the Common Stock and
on the first and second anniversaries of such date. Each non-employee director
elected thereafter shall be awarded an option to purchase 6,000 shares of Common
Stock at an exercise price equal to the fair market value of the Common Stock
upon his or her election as director, which will vest in three equal
installments commencing on the date of grant and on the first and second
anniversary of the date of grant. Each non-employee director will also receive
an option to purchase 4,000 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, which will vest in three equal
installments on the first, second, and third anniversaries of the date of grant.
The Compensation Committee also has the authority under the Director Option Plan
to grant options to non-employee directors in such amounts and in such terms not
inconsistent with the Director Option Plan as it shall determine at the time of
grant. All such options will be granted at fair market value. Each option will
be non-transferable except upon death and will expire 10 years after the date of
grant. A total of 150,000 shares of Common Stock has been reserved for issuance
under the Director Option Plan, 126,000 of which remain available for future
grants.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     During 1995, Mr. Colony was responsible for compensation decisions,
although he consulted as to such decisions with an outside compensation
consultant. Following this offering the Company will have a Compensation
Committee consisting of Messrs. Galford and Welles, neither of whom is an
employee of the Company.
 
REGISTRATION RIGHTS AND NON-COMPETITION AGREEMENT
 
     The Company and Mr. Colony have entered into a registration rights and
non-competition agreement (the "Registration Rights and Non-Competition
Agreement") which provides that if Mr. Colony's employment with the Company is
terminated he will not compete with the Company for the one-year period after
the date of such termination. The Registration Rights and Non-Competition
Agreement also provides Mr. Colony with certain registration rights with respect
to his Common Stock, described under "Description of Capital Stock".
 
                              CERTAIN TRANSACTIONS
 
     The Company and Mr. Colony intend to enter 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 ceases to be an S corporation, while the
Company will be liable for all income taxes subsequent to the time it ceases 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 from adjustments
initiated by taxing authorities.

                          DESCRIPTION OF CAPITAL STOCK
 
     The following summary describes the Certificate of Incorporation of the
Company, as restated in its entirety immediately prior to the consummation of
this offering.
 
GENERAL
 
   
     The authorized capital stock of the Company consists of 25,000,000 shares
of Common Stock, par value $.01 per share, and 500,000 shares of Preferred
Stock, par value $.01 per share (the "Preferred Stock"). As of September 30,
1996, there were 6,000,000 shares of Common Stock outstanding, held of record by
one stockholder, and no shares of Preferred Stock outstanding.
    
 
COMMON STOCK
 
   
     As of September 30, 1996, there were 6,000,000 shares of Common Stock
outstanding, all of which were held by Mr. Colony. Each holder of Common Stock
is entitled to one vote per share for the election of directors and for all
other matters to be voted on by the Company's stockholders. Subject to
preferences that may be applicable to any outstanding series of Preferred Stock,
the holders of Common Stock are entitled to share ratably in such dividends, if
any, as may be declared from time to time by the Board of Directors, from funds
legally available therefore. See "Dividend Policy". Upon liquidation or
dissolution of the Company, subject to preferences that may be applicable to any
then outstanding Preferred Stock, the holders of Common Stock are entitled to
receive in all assets available for distribution to stockholders. There are no
preemptive or other subscription rights, conversion rights, or redemption or
sinking fund provisions with respect to shares of Common Stock. All of the
outstanding shares of Common Stock are fully paid and nonassessable.
    
 
PREFERRED STOCK
 
     The Company's Restated Certificate of Incorporation (the "Certificate")
provides that the Company may, by vote of its Board of Directors, designate the
numbers, relative rights, preferences, and limitations of one or more series of
Preferred Stock and issue the securities so designated. Such provisions may
discourage or preclude certain transactions, whether or not beneficial to
stockholders, and could discourage certain types of tactics that involve an
actual or threatened acquisition or change of control of the Company. This
provision does not prevent stockholders from obtaining injunctive or other
relief against the directors, nor does it shield directors from liability under
federal or state securities laws.
 
     The Company has no current intention to issue any of its unissued,
authorized shares of Preferred Stock. However, the issuance of any shares of
Preferred Stock in the future could adversely affect the rights of the holders
of Common Stock.
 
REGISTRATION RIGHTS
 
     The Company and Mr. Colony have entered into a Registration Rights and
Non-Competition Agreement, which provides that in the event the Company proposes
to file a registration statement under the Securities Act with respect to an
offering by the Company for its own account or the account of another person, or
both, Mr. Colony shall be entitled to include shares held by him (the
"Registrable Shares") in such a registration, subject to the right of the
managing underwriter of any such offering to exclude some or all of such
Registrable Shares from such registration if and to the extent the inclusion of
the shares would adversely affect the marketing of the shares to be sold by the
Company. The agreement also provides that, at any time following the closing of
an initial public offering of Common Stock, Mr. Colony may require the Company
to register under the Securities Act shares having a fair market value of at
least $5.0 million, except that the Company is not required to effect such
registration more than twice or at certain times described in the agreement. The
 
                                       34
<PAGE>   36
 
agreement also provides that the Company will pay all expenses incurred in
connection with such registration.
 
DELAWARE LAW AND CERTAIN CHARTER AND BYLAW PROVISIONS
 
   
     Section 203 of the General Corporation Law of Delaware prohibits a publicly
held Delaware corporation from engaging in a "business combination" with an
"interested stockholder", other than an "interested stockholder" who is an
"interested stockholder" at the time the corporation becomes subject to Section
203, for a period of three years after the date of the transaction in which the
person became an interested stockholder, unless the business combination is
approved in a prescribed manner. A "business combination" includes mergers,
asset sales, and other transactions resulting in a financial benefit to the
interested stockholder. Subject to certain exceptions, an "interested
stockholder" is a person who, together with affiliates and associates, owns, or
within three years did own, 15% or more of the corporation's voting stock. The
Certificate provides that the Company will not be subject to the provisions of
Section 203.
    
 
   
     The Certificate and Bylaws provide for the division of the Board of
Directors into three classes as nearly equal in size as possible with staggered
three-year terms. See "Management". In addition, the Certificate of
Incorporation and Bylaws provide that directors may be removed only for cause by
the affirmative vote of the holders of two-thirds of the shares of capital stock
of the Company entitled to vote generally in the election of directors. Under
the Certificate and Bylaws, any vacancy on the Board of Directors, however
occurring, including a vacancy resulting from an enlargement of the Board, may
only be filled by vote of a majority of the directors then in office. The
classification of the Board of Directors and the limitations on the removal of
directors and filling of vacancies could have the effect of making it more
difficult for a third party to acquire, or of discouraging a third party from
acquiring, control of the Company.
    
 
     The Certificate and Bylaws also provide that any action required or
permitted to be taken by the stockholders of the Company at an annual meeting or
special meeting of stockholders may only be taken if it is properly brought
before such meeting and may not be taken by written action in lieu of a meeting.
The Certificate and Bylaws further provide that special meetings of the
stockholders may only be called by the Chairman of the Board of Directors, the
Chief Executive Officer, or, if none, the President of the Company or by the
Board of Directors. Under the Company's Bylaws, in order for any matter to be
considered "properly brought" before a meeting, a stockholder must comply with
certain requirements regarding advance notice to the Company. The foregoing
provisions could have the effect of delaying until the next stockholders'
meeting stockholder actions which are favored by the holders of a majority of
the outstanding voting securities of the Company. These provisions may also
discourage another person or entity from making a tender offer for the Common
Stock, because such person or entity, even if it acquired a majority of the
outstanding voting securities of the Company, would be able to take action as a
stockholder (such as electing new directors or approving a merger) only at a
duly called stockholders' meeting, and not by written consent.
 
   
     The General Corporation Law of Delaware provides generally that the
affirmative vote of a majority of the shares entitled to vote on any matter is
required to amend a corporation's Certificate of Incorporation or Bylaws, unless
a corporation's Certificate of Incorporation or Bylaws, as the case may be,
require a greater percentage. The Company's Certificate and the Bylaws require
the affirmative vote of the holders of at least 75% of the shares of capital
stock of the Company issued and outstanding and entitled to vote generally for
directors to amend, alter or repeal the By-Laws or to adopt new by-laws.
    
 
   
     The Certificate contains certain provisions permitted under the General
Corporation Law of Delaware relating to the liability of directors. The
provisions eliminate a director's liability to the Company or its stockholders
for monetary damages for a breach of fiduciary duty, except to the extent that
exculpation from liability is not permitted under the General Corporation Law of
Delaware as in effect at the time the liability is determined. The Certificate
also contains provisions obligating
    
 
                                       35
<PAGE>   37
 
the Company to indemnify its officers and directors to the fullest extent
permitted by the General Corporation Law of Delaware. The Company believes that
these provisions will assist the Company in attracting and retaining qualified
individuals to serve as directors.
 
TRANSFER AGENT AND REGISTRAR
 
     The Transfer Agent and Registrar for the Common Stock is The First National
Bank of Boston, Boston, Massachusetts.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion of this offering, the Company will have approximately
8,000,000 shares of Common Stock outstanding. Of these shares, the 2,000,000
shares sold in the offering will be freely tradeable without restriction or
further registration under the Securities Act, except for any shares purchased
by an "affiliate" of the Company, as that term is defined in Rule 144 under the
Securities Act (an "Affiliate"). Any shares purchased in the offering by an
Affiliate of the Company may not be resold except pursuant to an effective
registration statement filed by the Company or an applicable exemption from
registration, including the exemption under Rule 144. The remaining 6,000,000
shares will be subject to a 180-day lock-up agreement. After the 180-day period,
these shares will be eligible for sale subject to compliance with Rule 144 under
the Securities Act.
 
   
     In general, a person (or persons whose shares are aggregated for purposes
of such rule) effecting sales under Rule 144 is entitled to sell, within any
three-month period, a number of such securities that does not exceed the greater
of 1% of the then outstanding shares of the Company's Common Stock
(approximately 80,000 shares immediately after the offering) or the average
weekly trading volume in the Company's Common Stock on the Nasdaq National
Market or reported through the automated quotation system of a registered
securities association during the four calendar weeks preceding such sale. Sales
under Rule 144 are also subject to certain restrictions on the manner of sale,
notice requirements, and the availability of current public information about
the Company. The Company, Mr. Colony, who prior to the completion of this
offering is the sole stockholder of the Company, and directors, certain
executive officers and employees of the Company who hold options to purchase
582,945 shares of Common Stock, have agreed not to offer or sell or otherwise
dispose of any Common Stock with certain limited exceptions until the expiration
of 180 days following the date of this Prospectus without the prior written
consent of the Representatives of the Underwriters. See "Underwriting".
    
 
     No precise prediction can be made as to the effect, if any, that market
sales of shares or the availability of shares for sale will have on the market
price of the Common Stock prevailing from time to time. The Company is unable to
estimate the number of shares that may be sold in the public market pursuant to
Rule 144, since this will depend on the market price of Common Stock, the
personal circumstances of the sellers, and other factors. Nevertheless, sales or
anticipated sales of significant amounts of the Common Stock of the Company in
the public market could adversely affect the market price of the Company's
Common Stock.
 
   
     In addition, from time to time after the expiration of the 180-day lock-up
period, Mr. Colony may sell shares of the Company's Common Stock pursuant to a
registration statement filed in the future by the Company pursuant to the
Registration Rights and Non-Competition Agreement between the Company and Mr.
Colony. See "Description of Capital Stock -- Registration Rights".
    
 
   
     As of September 30, 1996, options to purchase a total of 772,691 shares of
Common Stock were outstanding, of which options to purchase 157,376 shares will
become exercisable upon completion of this offering. Of the total shares
issuable pursuant to such options 106,595 shares are subject to 180-day lock-up
agreements with the representatives of the Underwriters.
    
 
   
     The Company intends to file a registration statement on Form S-8 under the
Securities Act covering 200,000 shares of Common Stock reserved for issuance
under the Stock Purchase Plan upon consummation of this offering, although
shares will not be issuable under the plan until June
    
 
                                       36
<PAGE>   38
 
   
30, 1997. In addition, the Company intends to file registration statements on
Form S-8 covering 2,900,000 shares of Common Stock reserved for issuance under
the Equity Incentive Plan and the Director Option Plan. See "Management -- Stock
Plans". Such registration statements are expected to be filed 90 days after the
date of this Prospectus and will automatically become effective upon filing.
Accordingly, shares issued pursuant to such registration statements will,
subject to Rule 144 volume limitations applicable to Affiliates, be available
for sale in the open market. As of September 30, 1996, options to purchase
772,691 shares were granted and outstanding. Of the total shares issuable
pursuant to such options, 582,945 shares are subject to the lock-up agreements
discussed above.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Stockholder of
Forrester Research, Inc.:
 
   
     We have audited the accompanying balance sheets of Forrester Research, Inc.
(a Delaware corporation) as of December 31, 1994 and 1995 and September 30, 1996
and the related statements of income, stockholder's equity, and cash flows for
each of the three years in the period ended December 31, 1995 and for the
nine-month period ended September 30, 1996. 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. as
of December 31, 1994 and 1995 and September 30, 1996 and the results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1995 and for the nine-month period ended September 30, 1996, in
conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                (INCLUDING DATA APPLICABLE TO UNAUDITED PERIODS)
 
(1) OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES
 
     Forrester Research, Inc. (the Company) creates, publishes, and sells
technology research reports and provides advisory services and technology
conferences. The Company is incorporated under the laws of the State of Delaware
and grants credit to its customers with locations throughout the world.
 
     The preparation of the accompanying financial statements required the use
of certain estimates by management in determining the Company's assets,
liabilities, revenues, and expenses. Actual results could differ from these
estimates.
 
     The accompanying financial statements reflect the application of certain
significant accounting policies as described below and elsewhere in the
accompanying financial statements and notes.
 
  Interim Financial Statements
 
   
     The accompanying statements of income and cash flows for the nine months
ended September 30, 1995 are unaudited, but in the opinion of management,
include all adjustments (consisting of normal recurring adjustments) necessary
for a fair presentation of results for these interim periods. Certain
information and footnote disclosures normally included in financial statements
prepared in accordance with generally accepted accounting principles have been
omitted, although the Company believes that the disclosures included are
adequate to make the information presented not misleading. The results of
operations for the nine months ended September 30, 1996 are not necessarily
indicative of the results to be expected for the entire fiscal year.
    
 
  Pro Forma Presentation (Unaudited)
 
   
     The unaudited pro forma balance sheet, as of September 30, 1996, reflects
(i) the distribution of previously undistributed S corporation earnings taxed or
taxable to the Company's sole stockholder of approximately $3.6 million based on
earnings through September 30, 1996, but does not include the amount to be
distributed for S corporation earnings from October 1, 1996 through the
termination of the Company's S corporation election upon completion of this
offering, and (ii) termination of the Company's S corporation election and the
recognition of a deferred income tax liability of approximately $500,000 as of
September 30, 1996 (see Note 3).
    
 
     Upon completion of an initial public offering, the Company will no longer
be treated as an S corporation and will be subject to federal and state income
taxes at prevailing corporate rates. Accordingly, the accompanying statements of
income include a pro forma income tax adjustment reflecting the Company's income
tax expense assuming the Company had been a C corporation (see Note 3).
 
  Revenue Recognition
 
   
     The Company 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 legally obligated to pay the invoice. Core
research, which represents monthly distribution of research reports, is recorded
as revenue ratably over the term of the agreement as the research is delivered.
Advisory and other services are recognized during the period in which the
services are performed.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
                (INCLUDING DATA APPLICABLE TO UNAUDITED PERIODS)
 
  Deferred Commissions
 
   
     Commissions incurred in acquiring new or renewal contracts are deferred and
amortized as the related revenue is recognized. The Company evaluates the
recoverability of deferred commissions at each balance sheet date based on the
status of the related contract.
    
 
  Pro Forma Net Income Per Common Share
 
   
     Pro forma net income per common share is computed by dividing pro forma net
income (reflecting the pro forma income tax adjustment discussed in Note 3) by
the weighted average number of shares of common stock and common stock
equivalents outstanding during the period, adjusted for the reincorporation
discussed in Note 6. Common stock equivalents consist of common stock issuable
on the exercise of outstanding options. In accordance with Securities and
Exchange Commission requirements, all common stock and common stock equivalents
issued during the 12 months preceding the proposed date of the Registration
Statement relating to an initial public offering have been included in the net
income per share computation as if they were outstanding for all periods using
the Treasury Stock method.
    
 
   
  Depreciation
    
<TABLE>
 
     The Company provides for depreciation, computed using the straight-line
method, by charges to income in amounts that allocate the costs of these assets
over their estimated useful lives as follows:

  Product Development
 
     All costs incurred in 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. Financial
instruments, which potentially subject the Company to concentrations of credit
risk, are principally cash and 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 in
any of the periods presented.
    
 
  Financial Instruments
 
     SFAS No. 107, Disclosures About Fair Value of Financial Instruments,
requires disclosure about fair value of financial instruments. Financial
instruments consist of cash equivalents, marketable securities, and accounts
receivable. The estimated fair value of these financial instruments approximates
their carrying value and, except for accounts receivable, is based primarily on
market quotes. The Company's cash equivalents and marketable securities are
generally obligations of the federal

government or municipal issuers. The Company, by policy, limits the amount of
credit exposure to any one financial institution.
 
(2) CASH, CASH EQUIVALENTS AND MARKETABLE SECURITIES
 
     The Company considers all short-term, highly liquid investments with
original maturities of 90 days or less 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 that the Company has the positive intent and ability to hold to
maturity are reported at amortized cost and are classified as held-to-maturity.
At December 31, 1994 and 1995 and September 30, 1996, held-to-maturity
securities consisted of investments in U.S. treasury bills. These investments
are classified as current as they mature within one year. Securities purchased
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, 1995 and September 30, 1996, these securities
consisted of investments in federal and state government obligations, which were
recorded at fair market value, with any unrealized gains and losses reported as
a separate component of stockholder's equity. These investments were classified
as marketable securities at December 31, 1995 and September 30, 1996 as it is
the Company's intent to hold these securities less than one year. There were no
available-for-sale securities as of December 31, 1994. Securities that are
bought and held principally for the purpose of selling in the near term are
classified as trading securities. There were no trading securities as of
December 31, 1994 and 1995 and September 30, 1996.

(3) INCOME TAXES
 
     The Company has elected to be taxed, since January 1, 1987, under
Subchapter S of the Internal Revenue Code of 1986, as amended, whereby the sole
stockholder is liable for individual federal and state income taxes on the
Company's taxable income. Payments to the stockholder to cover the tax
liabilities as a result of the Company's taxable income are recorded as
distributions in the accompanying statements of stockholder's equity.
 
   
     The Company's state income tax provision for each of the periods presented
consists of corporate-level state income taxes that are levied against the
Company as an S corporation.
    
 
   
     The Company accounts for income taxes, including pro forma computations, in
accordance with SFAS No. 109, Accounting for Income Taxes. SFAS No. 109
prescribes an asset and liability approach that requires the recognition of
deferred tax assets and liabilities for the expected future tax consequences of
temporary differences between the financial statement carrying amounts and the
tax bases of assets and liabilities. Deferred state taxes as of December 31,
1994 and 1995 and September 30, 1996 were immaterial.
    
 
   
     Upon completion of an initial public offering, the Company will terminate
its S corporation election and will be subject to federal and state income taxes
at prevailing corporate rates. Accordingly, the accompanying statements of
income for each of the three years in the period ended December 31, 1995 and the
nine months ended September 30, 1995 and 1996 include a pro forma income tax
adjustment for the income taxes that would have been recorded if the Company had
been a C corporation for the periods presented.
    
<TABLE>
 
     The pro forma income tax adjustment is computed as follows:

     Upon termination of the S corporation election, deferred income taxes will
be recorded for the tax effect of cumulative temporary differences between the
financial reporting and tax bases of certain assets and liabilities, primarily
deferred commissions, accrued expenses, and cumulative tax depreciation in
excess of financial reporting allowances. If the S corporation election had been

terminated at September 30, 1996, these temporary differences would have
resulted in a net deferred income tax liability of approximately $500,000. The
Company will record this tax liability as a one-time increase in the tax
provision in the period in which the S corporation election is terminated. As
this is a nonrecurring charge it has been excluded from the pro forma income tax
adjustment.

     The Company leases its office space under an operating lease. The Company
will also make lease payments on its previous facility through January 1997. The

(5) 401(k) PLAN
 
   
     The Company has a 401(k) savings plan covering substantially all eligible

(6) STOCKHOLDER'S EQUITY
    
 
  (a) Reincorporation
 
   
     In February 1996, in connection with the Company's reincorporation in
Delaware, the Company increased the number of authorized shares of common stock
to 7,000,000, and each outstanding share of common stock was exchanged for 6,000
shares of common stock in the reincorporated entity. The accompanying financial
statements and notes have been retroactively adjusted to reflect this
transaction. The Board of Directors has voted to amend the Company's Certificate
of Incorporation to increase the number of authorized shares of common stock to
25,000,000 immediately prior to completion of an initial public offering.
    
 
  (b) Stock Option Plans
 
     In February 1996, the Company adopted the Forrester Research, Inc. 1996
Equity Incentive Plan, which was amended in September 1996 (the Plan). The Plan
provides for the issuance of

incentive stock options (ISOs) and nonqualified stock options (NSOs) to purchase
up to 2,750,000 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 of
not less than 110% of the fair market value at the date of grant. The fair
market value of $5.50 per share for the options granted in February 1996 was
based on an independent appraisal. Options vest ratably over three years and
expire after 10 years. Options granted under the Plan immediately vest upon
certain events, as defined.

the Plan are 2,001,309.
    
 
   
     In September 1996, the Company adopted the 1996 Stock Option Plan for
Non-Employee Directors (the Director's Plan) which provides for the issuance of
options to purchase up to 150,000 shares of common stock. The Director's Plan
provides that the four non-employee directors who have agreed to serve as
directors of the Company will receive, on the date that the Company first files
a registration statement under the Securities Act of 1933 covering the common
stock, an option to purchase 6,000 shares of the Company's common stock at an
exercise price of $13.00 per share. Such options will vest in three equal
installments commencing on the date of completion of the initial public offering
of the common stock and on the first and second anniversaries of such date. Each
non-employee director elected thereafter shall be awarded options to purchase
6,000 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, which will
vest in three equal installments commencing on the date of grant and on the
first and second anniversaries of the date of grant. Each non-employee director
will also receive an option to purchase 4,000 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, which will vest
in three equal installments on the first, second and third anniversaries of the
date of grant. The Compensation Committee of the Board of Directors also has the
authority under the Director's Plan to grant options to non-employee directors
in such amounts and on such terms as set forth in the Director's Plan as it
shall determine at the time of grant.

<TABLE>
     In October 1995, the Financial Accounting Standards Board (FASB) issued
SFAS No. 123, Accounting for Stock-Based Compensation. SFAS No. 123 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 pro forma disclosures required under SFAS No. 123 for options
granted in 1996 using the Black-Scholes option pricing model prescribed by SFAS
No. 123. The weighted average assumptions used for 1996 are:

</TABLE>
    
 
   
<TABLE>
     The total value of options granted during the nine months ended September
30, 1996 was computed as approximately $2,614,000. Of this amount approximately
$252,000 would be charged to operations for the nine months ended September 30,
1996 for currently vested options and the remaining amount, approximately
$2,362,000, would be amortized over the related vesting periods. There were no
options or warrants issued prior to 1996. The pro forma effect of SFAS No. 123
for the period ended September 30, 1996 is as follows:

  (c) Employee Stock Purchase Plan
 
     In September 1996, the Company adopted the 1996 Employee Stock Purchase
Plan (the Stock Purchase Plan) that provides for the issuance of up to 200,000
shares of common stock. The Stock Purchase Plan is administered by the Board of
Directors. With certain limited exceptions, all employees of the Company
employed more than 30 hours per week, including officers and directors who are
employees, are eligible to participate in the Stock Purchase Plan. The Stock
Purchase Plan consists of semiannual offerings on January 1 and July 1 of each
year. The first offering under the Stock Purchase Plan will commence on the
first day the Company's common stock is publicly traded on the Nasdaq National
Market and will end on June 30, 1997. Each subsequent offering under the Stock
Purchase Plan will be six months in length and will commence on each successive
July 1 and January 1. During each offering under the Plan, the maximum number of
shares of common stock that may be purchased by an employee is determined on the
first day of the offering period under a formula whereby an amount equal to that
percentage of the employee's regular salary that he or she has elected to have
withheld is divided by 85% of the market value of a share of common stock on the
first day of the offering 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 offering commences, or (b) 85% of the closing price of the
common stock on the day that the offering terminates. No shares have been
purchased under the Stock Purchase Plan.

  (d) Preferred Stock
 
     In September 1996, the Board of Directors voted to amend the Company's
Certificate of Incorporation to permit the issuance of up to 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.

</TABLE>
 
     Under the terms and conditions of the Underwriting Agreement, the
Underwriters are committed to take and pay for all of the shares offered hereby,
if any are taken.
 
     The Underwriters propose to offer the shares of Common Stock in part
directly to the public at the initial public offering price set forth on the
cover page of this Prospectus and in part to certain securities dealers at such
price less a concession of $       per share. The Underwriters may allow, and
such dealers may reallow, a concession not in excess of $       per share to
certain brokers and dealers. After the shares of Common Stock are released for
sale to the public, the offering price and other selling terms may from time to
time be varied by the representatives.
 
     The Company has granted the Underwriters an option exercisable for 30 days
after the date of this Prospectus to purchase up to an aggregate of 300,000
additional shares of Common Stock to cover over-allotments, if any. If the
Underwriters exercise their over-allotment option, the Underwriters have
severally agreed, subject to certain conditions, to purchase approximately the
same percentage thereof that the number of shares to be purchased by each of
them, as shown in the foregoing table, bears to the 2,000,000 shares of Common
Stock offered.
 
   
     The Company, Mr. Colony, who prior to the completion of the offering is the
sole stockholder of the Company, and directors, certain executive officers, and
other employees of the Company who hold options to purchase 582,945 shares of
Common Stock have agreed that with certain limited exceptions, during the period
beginning from the date of this Prospectus and continuing to and including the
date 180 days after the date of this Prospectus, they will not offer, sell,
contract to sell, or otherwise dispose of any securities of the Company (other
than pursuant to employee stock option plans existing, or on the conversion or
exchange of convertible or exchangeable securities outstanding, on the date of
this Prospectus) which are substantially similar to the shares of Common Stock
or which are convertible into or exchangeable for securities which are
substantially similar to the shares of Common Stock without the prior written
consent of the representatives, except for the shares of Common Stock offered in
connection with this offering.
    
 
   
     The representatives of the Underwriters have informed the Company that they
do not expect sales to accounts over which the Underwriters exercise
discretionary authority to exceed 5% of the total number of shares of Common
Stock offered by them.
    
 
     Prior to this offering, there has been no public market for the shares. The
initial public offering price will be negotiated among the Company and the
representatives. Among the factors to be considered in determining the initial
public offering price of the Common Stock, in addition to prevailing market
conditions, will be the Company's historical performance, estimates of the
business potential and earnings prospects of the Company, an assessment of the
Company's management, and the consideration of the above factors in relation to
market valuation of companies in related businesses.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
   
     The Registrant's Certificate of Incorporation provides that the
Registrant's Directors shall not be liable to the Registrant or its stockholders
for monetary damages for breach of fiduciary duty as a director, except to the
extent that the exculpation from liabilities is not permitted under the Delaware
General Corporation Law as in effect at the time such liability is determined.
    
 
ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES
 
     In the three years preceding the filing of this Registration Statement, the
Registrant has not sold any securities which were not registered under the
Securities Act of 1933, as amended (the "Securities Act").
 
   
     The Registrant has awarded to employees and directors options to purchase
782,691 shares of Common Stock, none of which have become exercisable prior to
the date hereof. The Registrant also issued 6,000,000 shares of Common Stock to
its sole stockholder in February 1996 in connection with its reincorporation
merger in Delaware. Such transaction was not a "sale" because it fit within the
exemption under Rule 145(a)(2) under the Securities Act.

        Schedule II -- Valuation and Qualifying Accounts
 
     All other schedules for which provision is made in Regulations S-X of the
Securities and Exchange Commission are not required under the related
instructions or are inapplicable and, therefore, have been omitted.
 
ITEM 17.  UNDERTAKINGS
 
     (a) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers, and controlling persons of the
Registrant pursuant to the provisions described under "Item 14 --
Indemnification of Directors and Officers" above, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer, or controlling person of the Registrant
in the successful defense of any action, suit, or proceeding) is asserted by
such director, officer, or controlling person in connection with the securities
being registered, the Registrant will, unless in
 
                                      II-2
<PAGE>   59
 
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.
 
     (b) The undersigned Registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities
     Act, the information omitted from the form of prospectus filed as part of
     this Registration Statement in reliance upon Rule 430A and contained in a
     form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     Registration Statement as of the time it was declared effective.
 
          (2) For the purposes of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of prospectus shall
     be deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.
 
     The undersigned Company hereby undertakes to provide at the closing of this
offering to the Underwriters specified in the Underwriting Agreement
certificates in such denominations and registered in such names as required by
the Underwriters to permit prompt delivery to each purchaser.

              REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS ON SCHEDULE
 
To the Stockholder of
Forrester Research, Inc.:
 
   
     We have audited in accordance with generally accepted auditing standards,

responsibility of the Company's management and is presented for purposes of
complying with the Securities and Exchange Commission's rules and is not part of

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

     shares of Stock have been duly authorized and validly issued and are fully
     paid and nonassessable; the Shares have been duly authorized and, when
     issued and delivered in accordance with this Agreement, will be validly
     issued, fully paid and nonassessable and will conform in all material
     respects to the description of the Stock contained in the Prospectus.

          (iii) To the knowledge of such counsel, and other than as set forth in
     the Prospectus, there are no legal or governmental proceedings pending to
     which the Company is a party or of which any property of the Company is the
     subject.

          (iv) This Agreement has been duly authorized, executed and delivered
     by the Company.

          (v) The issuance and sale by the Company of the Shares and the

     its properties is subject, or (iii) violate any existing Delaware
     corporate, Massachusetts or federal law, rule, administrative regulation or
     any decree known to such counsel of any court or any governmental agency or

     qualification of or with any court or governmental agency or body of the

          (vii) The Company is not subject to regulation as an "investment
     company" under the Investment Company Act of 1940, as amended.

          (viii) The statements set forth in the Prospectus under the caption
     "Description of Capital Stock," insofar as they purport to constitute a
     summary of the terms of the Stock and under the caption "Underwriting",
     insofar as they purport to describe the provisions of the laws and
     documents referred to therein, accurately summarize in all material
     respects the provisions of the laws and documents referred to therein; and

     therein, as to which such counsel need express no opinion) comply as to
     form in all material respects with the requirements of the Act and the
     rules and regulations thereunder; although they do not assume any
     responsibility for the accuracy, completeness or fairness of the statements
     contained in the Registration Statement or the Prospectus, except for those
     referred to in the opinion in subsection (xi) of this Section 7(c), nothing
     came to such counsel's attention that caused them to believe that, as of
     its effective date, the Registration Statement or any further amendment
     thereto made by the Company prior to such Time of Delivery (other than the
     financial statements and related schedules therein, as to which such
     counsel need express no opinion) contained an untrue statement of a
     material fact or omitted to state a material fact required to be stated

     as of its date, the Prospectus or any further amendment or supplement
     thereto made by the Company prior to such Time of Delivery (other than the
     financial statements and related schedules therein, as to which such
     counsel need express no opinion) contained an untrue statement of a
     material fact or omitted to state a material fact necessary to make the
     statements therein, in the light of the circumstances under which they were
     made, not misleading or that, as of such Time of Delivery, either the
     Registration Statement or the Prospectus or any further amendment or
     supplement thereto made by the Company prior to such Time of Delivery
     (other than the financial statements and related schedules therein, as to
     which such counsel need express no opinion) contains an untrue statement of
     a material fact or omits to state a material fact necessary to make the
     statements therein, in the light of the circumstances under which they were
     made, not misleading; and they do not know of any amendment to the
     Registration Statement required to be filed or of any contracts or other
     documents of a character required to be filed as an exhibit to the
     Registration Statement or required to be described in the Registration
     Statement or the Prospectus which are not filed or described as required.

     (d)  On the date of the Prospectus at a time prior to the execution of this
Agreement, at 9:30 a.m., New York City time, on the effective date of any
post-effective


                                      -12-

amendment to the Registration Statement filed subsequent to the date of this
Agreement and also at each Time of Delivery, Arthur Andersen LLP shall have
furnished to you a letter or letters, dated the respective dates of delivery
thereof, in form and substance reasonably satisfactory to you, to the effect set
forth in Annex I hereto (the executed copy of the letter delivered prior to the

covered by insurance, or from any labor dispute or court or governmental action,
order or decree, otherwise than as set forth or contemplated in the Prospectus,
and (ii) since the respective dates as of which information is given in the
Prospectus there shall not have been any change in the capital stock or
long-term debt of the Company or any change, or any development that is
reasonably likely to result in a material adverse change, in or affecting the
business, assets, financial position, stockholders' equity or results of
operations of the Company, otherwise than as set forth or contemplated in the
Prospectus, the effect of which, in any such case described in clause (i) or
(ii), is in the judgment of the Representatives so material and adverse as to
make it impracticable or inadvisable to proceed with the public offering or the
delivery of the Shares being delivered at such Time of Delivery on the terms and
in the manner contemplated in the Prospectus;

     (f)  On or after the date hereof there shall not have occurred any of the

United States or the declaration by the United States of a national emergency or
war, if the effect of any such event specified in this Clause (iv) in the
judgment of the Representatives makes it impracticable or inadvisable to proceed
with the public offering or the delivery of the Shares being delivered at such
Time of Delivery on the terms and in the manner contemplated in the Prospectus;

     (g)  The Shares at the such Time of Delivery shall have been duly listed 
for quotation on the NASDAQ National Market;

     (h)  The Company shall have obtained and delivered to the Underwriters
copies of an agreement from each person listed on Schedule III hereto to the
effect that during the period beginning from the date hereof and continuing to
and including the date 180 days after the date of the Prospectus, such person
shall not offer, sell, contract to sell or otherwise dispose of, except as
provided hereunder, any Stock, or any securities of the

Company that are substantially similar to the Shares, including but not limited
to any securities that are convertible into or exchangeable for, or that
represent the right to receive, Stock or any such substantially similar
securities (other than pursuant to employee stock option plans existing on the
date of this Agreement), without your prior written consent;

     (i)  The Company shall have furnished or caused to be furnished to you at
such Time of Delivery certificates of officers of the Company reasonably
satisfactory to you as to the accuracy of the representations and warranties of
the Company herein at and as of such Time of Delivery, as to the performance by
the Company of all of its obligations hereunder to be performed at or prior to
such Time of Delivery, and as to such other matters as you may reasonably
request, and the Company shall have furnished or caused to be furnished
certificates as to the matters set forth in subsections (a) and (e) of this
Section;

     (j)  The Company shall have complied with the provisions of Section 5(c)
hereof with respect to the furnishing of prospectuses on the New York Business
Day next succeeding the date of this Agreement; and

     (k)  The Company and George F. Colony shall have entered into a Tax
Indemnification Agreement in a form acceptable to the Underwriters and their
counsel (the "Tax Indemnification Agreement").

     8.   (a) The Company will indemnify and hold harmless each Underwriter
against any losses, claims, damages or liabilities, joint or several, to which
such Underwriter may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon an untrue statement or alleged untrue statement of a
material fact contained in any Preliminary Prospectus, the Registration
Statement or the Prospectus, or any amendment or supplement thereto, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and will reimburse each Underwriter for any legal or
other expenses reasonably incurred by such Underwriter in connection with
investigating or defending any such action or claim as such expenses are
incurred; provided, however, that the Company shall not be liable in any such
case to the extent that any such loss, claim, damage or liability arises out of
or is 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 such amendment or supplement in reliance upon and in
conformity with written information furnished to the Company by any Underwriter
through Goldman, Sachs & Co. expressly for use therein.

     (b)  Each Underwriter will indemnify and hold harmless the Company against
any losses, claims, damages or liabilities to which the Company may become
subject, under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in


                                      -14-

<PAGE>   15



respect thereof) arise out of or are based upon an untrue statement or alleged
untrue statement of a material fact contained in any Preliminary Prospectus, the
Registration Statement or the Prospectus, or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, in each case to the extent, but only to
the extent, that such untrue statement or alleged untrue statement or omission
or alleged omission was made in any Preliminary Prospectus, the Registration
Statement or the Prospectus or any such amendment or supplement in reliance upon
and in conformity with written information furnished to the Company by such
Underwriter through Goldman, Sachs & Co. expressly for use therein; and will
reimburse the Company for any legal or other expenses reasonably incurred by the
Company in connection with investigating or defending any such action or claim
as such expenses are incurred.

     (c)  Promptly after receipt by an indemnified party under subsection (a) or
(b) above of notice of the commencement of any action, such indemnified party
shall, if a claim in respect thereof is to be made against the indemnifying
party under such subsection, notify the indemnifying party in writing of the
commencement thereof; but the omission so to notify the indemnifying party shall
not relieve it from any liability which it may have to any indemnified party
otherwise than under such subsection. In case any such action shall be brought
against any indemnified party and it shall notify the indemnifying party of the
commencement thereof, the indemnifying party shall be entitled to participate
therein and, to the extent that it shall wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with
counsel satisfactory to such indemnified party (who shall not, except with the
consent of the indemnified party, be counsel to the indemnifying party), and,
after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof, the indemnifying party shall not be
liable to such indemnified party under such subsection for any legal expenses of
other counsel or any other expenses, in each case subsequently incurred by such
indemnified party, in connection with the defense thereof other than reasonable
costs of investigation. No indemnifying party shall, without the written consent
of the indemnified party, effect the settlement or compromise of, or consent to
the entry of any judgment with respect to, any pending or threatened action or
claim in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified party is an actual or potential party
to such action or claim) unless such settlement, compromise or judgment (i)
includes an unconditional release of the indemnified party from all liability
arising out of such action or claim and (ii) does not include a statement as to
or an admission of fault, culpability or a failure to act, by or on behalf of
any indemnified party.

     (d)  If the indemnification provided for in this Section 8 is unavailable 
to or insufficient to hold harmless an indemnified party under subsection (a) or
(b) above in respect of any losses, claims, damages or liabilities (or actions
in respect thereof) referred to therein, then each indemnifying party shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages or liabilities (or actions


                                      -15-

<PAGE>   16



in respect thereof) in such proportion as is appropriate to reflect the relative
benefits received by the Company on the one hand and the Underwriters on the
other from the offering of the Shares. If, however, the allocation provided by
the immediately preceding sentence is not permitted by applicable law or if the
indemnified party failed to give the notice required under subsection (c) above,
then each indemnifying party shall contribute to such amount paid or payable by
such indemnified party in such proportion as is appropriate to reflect not only
such relative benefits but also the relative fault of the Company on the one
hand and the Underwriters on the other in connection with the statements or
omissions which resulted in such losses, claims, damages or liabilities (or
actions in respect thereof), as well as any other relevant equitable
considerations. The relative benefits received by the Company on the one hand
and the Underwriters on the other shall be deemed to be in the same proportion
as the total net proceeds from the offering (before deducting expenses) received
by the Company bear to the total underwriting discounts and commissions received
by the Underwriters, in each case as set forth in the table on the cover page of
the Prospectus. The relative fault shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by the Company on the one hand or the Underwriters on the
other and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Company and
the Underwriters agree that it would not be just and equitable if contributions
pursuant to this subsection (d) were determined by pro rata allocation (even if
the Underwriters were treated as one entity for such purpose) or by any other
method of allocation which does not take account of the equitable considerations
referred to above in this subsection (d). The amount paid or payable by an
indemnified party as a result of the losses, claims, damages or liabilities (or
actions in respect thereof) referred to above in this subsection (d) shall be
deemed to include any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such action
or claim. Notwithstanding the provisions of this subsection (d), no Underwriter
shall be required to contribute any amount in excess of the amount by which the
total price at which the Shares underwritten by it and distributed to the public
were offered to the public exceeds the amount of any damages which such
Underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The Underwriters' obligations in this subsection
(d) to contribute are several in proportion to their respective underwriting
obligations and not joint.

     (e)  The obligations of the Company under this Section 8 shall be in
addition to any liability which the Company may otherwise have and shall extend,
upon the same terms and conditions, to each person, if any, who controls any
Underwriter within the meaning of the Act; and the obligations of the
Underwriters under this Section 8 shall be in addition to any liability which
the respective Underwriters may otherwise have and shall extend, upon the same
terms and conditions, to each officer and director of the Company


                                      -16-

<PAGE>   17



(including any person who, with his or her consent, is named in the Registration
Statement as about to become a director of the Company) and to each person, if
any, who controls the Company within the meaning of the Act.

     9.   (a) If any Underwriter shall default in its obligation to purchase the
Shares which it has agreed to purchase hereunder at a Time of Delivery, you may
in your discretion arrange for you or another party or other parties to purchase
such Shares on the terms contained herein. If within thirty-six hours after such
default by any Underwriter you do not arrange for the purchase of such Shares,
then the Company shall be entitled to a further period of thirty-six hours
within which to procure another party or other parties satisfactory to you to
purchase such Shares on such terms. In the event that, within the respective
prescribed periods, you notify the Company that you have so arranged for the
purchase of such Shares, or the Company notifies you that they have so arranged
for the purchase of such Shares, you or the Company shall have the right to
postpone such Time of Delivery for a period of not more than seven days, in
order to effect whatever changes may thereby be made necessary in the
Registration Statement or the Prospectus, or in any other documents or
arrangements, and the Company agrees to file promptly any amendments to the
Registration Statement or the Prospectus which in your opinion may thereby be
made necessary. The term "Underwriter" as used in this Agreement shall include
any person substituted under this Section with like effect as if such person had
originally been a party to this Agreement with respect to such Shares.

     (b)  If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Company as
provided in subsection (a) above, the aggregate number of such Shares which
remains unpurchased does not exceed one-eleventh of the aggregate number of all
the Shares to be purchased at such Time of Delivery, then the Company shall have
the right to require each non-defaulting Underwriter to purchase the number of
Shares which such Underwriter agreed to purchase hereunder at such Time of
Delivery and, in addition, to require each non-defaulting Underwriter to
purchase its pro rata share (based on the number of Shares which such
Underwriter agreed to purchase hereunder) of the Shares of such defaulting
Underwriter or Underwriters for which such arrangements have not been made; but
nothing herein shall relieve a defaulting Underwriter from liability for its
default.

     (c)  If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Company as
provided in subsection (a) above, the aggregate number of such Shares which
remains unpurchased exceeds one-eleventh of the aggregate number of all of the
Shares to be purchased at such Time of Delivery, or if the Company shall not
exercise the right described in subsection (b) above to require non-defaulting
Underwriters to purchase Shares of a defaulting Underwriter or Underwriters,
then this Agreement (or, with respect to the Second Time of Delivery, the
obligations of the Underwriters to purchase and of the Company to sell the
Optional Shares) shall thereupon terminate, without liability on the part of any
non-defaulting Underwriter or the Company, except for the expenses to be borne
by the


                                      -17-

<PAGE>   18



Company and the Underwriters as provided in Section 6 hereof and the indemnity
and contribution agreements in Section 8 hereof; but nothing herein shall
relieve a defaulting Underwriter from liability for its default.

     10.  The respective indemnities, agreements, representations, warranties 
and other statements of the Company and the several Underwriters, as set forth
in this Agreement or made by or on behalf of them, respectively, pursuant to
this Agreement, shall remain in full force and effect, regardless of any
investigation (or any statement as to the results thereof) made by or on behalf
of any Underwriter or any controlling person of any Underwriter, or the Company,
or any officer or director or controlling person of the Company, and shall
survive delivery of and payment for the Shares.

     11.  If this Agreement shall be terminated pursuant to Section 9 hereof, 
the Company shall not then be under any liability to any Underwriter except as
provided in Sections 6 and 8 hereof; but, if for any other reason any Shares are
not delivered by or on behalf of the Company as provided herein, the Company
will reimburse the Underwriters through you for all out-of-pocket expenses
approved in writing by you, including fees and disbursements of counsel,
reasonably incurred by the Underwriters in making preparations for the purchase,
sale and delivery of the Shares not so delivered, but the Company shall then be
under no further liability to any Underwriter in respect of the Shares not so
delivered except as provided in Sections 6 and 8 hereof.

     12.  In all dealings hereunder, you shall act on behalf of each of the
Underwriters, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement on behalf of any Underwriter made or
given by you jointly or by Goldman, Sachs & Co. on behalf of you as the
representatives.

     All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters shall be delivered or sent by mail, telex or
facsimile transmission to you as the representatives in care of Goldman, Sachs &
Co., 85 Broad Street, New York, New York 10004, Attention: Registration
Department; and if to the Company shall be delivered or sent by mail, telex or
facsimile transmission to the address of the Company set forth in the
Registration Statement, Attention: Secretary; provided, however, that any notice
to an Underwriter pursuant to Section 8(c) hereof shall be delivered or sent by
mail, telex or facsimile transmission to such Underwriter at its address set
forth in its Underwriters' Questionnaire or telex constituting such
Questionnaire, which address will be supplied to the Company by you on request.
Any such statements, requests, notices or agreements shall take effect upon
receipt thereof.

     13.  This Agreement shall be binding upon, and inure solely to the benefit
of, the Underwriters, the Company and, to the extent provided in Sections 8 and
10 hereof, the officers and directors of the Company and each person who
controls the Company or any Underwriter, and their respective heirs, executors,
administrators, successors and assigns, and no other person shall acquire or
have any right under or by virtue of this Agreement.

No purchaser of any of the Shares from any Underwriter shall be deemed a
successor or assign by reason merely of such purchase.

     14.  Time shall be of the essence of this Agreement. As used herein, the
term "business day" shall mean any day when the Commission's office in
Washington, D.C. is open for business.

     15.  This Agreement shall be governed by and construed in accordance with
the laws of the State of New York.

     16.  This Agreement may be executed and delivered by any one or more of the
parties hereto in any number of counterparts, each of which shall be deemed to
be an original, but all such counterparts when so executed and delivered shall
together constitute one and the same instrument.

     If the foregoing is in accordance with your understanding, please sign and
return to us seven counterparts hereof, and upon the acceptance hereof by you,
on behalf of each of the Underwriters, this letter and such acceptance hereof
shall constitute a binding agreement among each of the Underwriters and the
Company. It is understood that your acceptance of this letter on behalf of each
of the Underwriters is pursuant to the authority set forth in a form of
Agreement among Underwriters, the form of which shall be submitted to the
Company for examination, upon request, but without warranty on your part as to
the authority of the signers thereof.

                                Very truly yours,

     Pursuant to Section 7(d) of the Underwriting Agreement, the accountants
shall furnish letters to the Underwriters to the effect that:

          (i) They are independent certified public accountants with respect to
     the Company and its subsidiaries within the meaning of the Act and the
     applicable published rules and regulations thereunder;

          (ii) In their opinion, the financial statements and any supplementary
     financial information and schedules (and, if applicable, financial
     forecasts and/or pro forma financial information) examined by them and
     included in the Prospectus or the Registration Statement comply as to form
     in all material respects with the applicable accounting requirements of the
     Act and the related published rules and regulations thereunder; and they
     have made a review in accordance with standards established by the American
     Institute of Certified Public Accountants of the unaudited consolidated
     interim financial statements, selected financial data, pro forma financial
     information, financial forecasts and/or condensed financial statements
     derived from audited financial statements of the Company for the periods
     specified in such letter, as indicated in their reports thereon, copies of
     which have been separately furnished to the representatives of the
     Underwriters (the "Representatives");

          (iii) They have made a review in accordance with standards established
     by the American Institute of Certified Public Accountants of the unaudited
     condensed consolidated statements of income, consolidated balance sheets
     and consolidated statements of cash flows included in the Prospectus as
     indicated in their reports thereon copies of which have been separately
     furnished to the Representatives and on the basis of specified procedures
     including inquiries of officials of the Company who have responsibility for
     financial and accounting matters regarding whether the unaudited condensed
     consolidated financial statements referred to in paragraph (vi)(A)(i) below
     comply as to form in all material respects with the applicable accounting
     requirements of the Act and the related published rules and regulations,
     nothing came to their attention that caused them to believe that the
     unaudited condensed consolidated financial statements do not comply as to
     form in all material respects with the applicable accounting requirements
     of the Act and the related published rules and regulations;

          (iv) They have compared the information in the Prospectus under
     selected captions with the disclosure requirements of Regulation S-K and on
     the basis of limited procedures specified in such letter nothing came to
     their attention as a result of the foregoing procedures that caused them to
     believe that this information does not conform in all material respects
     with the disclosure requirements of Items 301, 302, 402 and 503(d),
     respectively, of Regulation S-K;


                                       -1-

<PAGE>   25



          (v) On the basis of limited procedures, not constituting an
     examination in accordance with generally accepted auditing standards,
     consisting of a reading of the unaudited financial statements and other
     information referred to below, a reading of the latest available interim
     financial statements of the Company and its subsidiaries, inspection of the
     minute books of the Company and its subsidiaries since the date of the
     latest audited financial statements included in the Prospectus, inquiries
     of officials of the Company and its subsidiaries responsible for financial
     and accounting matters and such other inquiries and procedures as may be
     specified in such letter, nothing came to their attention that caused them
     to believe that:

               (A) (i) the unaudited consolidated statements of income,
          consolidated balance sheets and consolidated statements of cash flows
          included in the Prospectus do not comply as to form in all material
          respects with the applicable accounting requirements of the Act and
          the related published rules and regulations, or (ii) any material
          modifications should be made to the unaudited condensed consolidated
          statements of income, consolidated balance sheets and consolidated
          statements of cash flows included in the Prospectus for them to be in
          conformity with generally accepted accounting principles;

               (B) any other unaudited income statement data and balance sheet
          items included in the Prospectus do not agree with the corresponding
          items in the unaudited consolidated financial statements from which
          such data and items were derived, and any such unaudited data and
          items were not determined on a basis substantially consistent with the
          basis for the corresponding amounts in the audited consolidated

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

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 a 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.

                                   ARTICLE VI

     The election of directors need not be by written ballot unless the by-laws

                                   ARTICLE VII

     In furtherance of and not in limitation of the powers conferred upon the
board of directors by law, the board of directors shall have power to make,
adopt, alter, amend and repeal from time to time by-laws of this corporation,
subject to the right of the stockholders entitled to vote with respect thereto
to alter and repeal by-laws made by the board of directors PROVIDED, HOWEVER,
that the By-Laws shall not be altered, amended or repealed by the stockholders
of this corporation except by the holders of not less than seventy-five percent
(75%) of the shares of capital stock of this corporation issued and outstanding
and entitled to vote generally in the election of directors.

                                  ARTICLE VIII

     A director of this corporation shall not be liable to this corporation or
its stockholders for monetary damages for breach of fiduciary duty as a
director, except to the extent that exculpation from liability is not permitted
under the General Corporation Law of the State of Delaware as in effect at the
time the liability is determined. No amendment to or repeal of this provision
shall apply to or have any effect on the liability or alleged liability of any
director of this corporation for or with respect to any acts or omissions of
such director occurring prior to such amendment or repeal.

                                   ARTICLE IX

     This corporation shall, to the maximum extent permitted from time to time
under the law of the State of Delaware, indemnify and upon request advance
expenses to any person who is or was a party or is threatened to be made a party
to any threatened, pending or completed action, suit, proceeding or claim,
whether civil, criminal, administrative or investigative, by reason of the fact
that such person is or was or has agreed to be a director or officer of this
corporation or while a director or officer is or was serving at the request of
this corporation as a director, officer, partner, trustee, employee or agent of
any corporation, partnership, joint venture, trust or other enterprise,

against expenses (including attorney's fees and expenses), judgments, fines,
penalties and amounts paid in settlement incurred (and not otherwise recovered)
in connection with the investigation, preparation to defend or defense of such
action, suit, proceeding or claim; PROVIDED, HOWEVER, that the foregoing shall
not require this corporation to indemnify or advance expenses to any person in
connection with any action, suit, proceeding, claim or counterclaim initiated by
or on behalf of such person. Such indemnification shall not be exclusive of
other indemnification rights arising under any by-law, agreement, vote of
directors or stockholders or otherwise and shall inure to the benefit of the
heirs and legal representatives of such person. Any person seeking
indemnification under this Article IX shall be deemed to have met the standard
of conduct required for such indemnification unless the contrary shall be
established. Any repeal or modification of the foregoing provisions of this
Article IX shall not adversely affect any right or protection of a director or
officer of this corporation with respect to any acts or omissions of such
director or officer occurring prior to such repeal or modification.

                                    ARTICLE X

     Until the consummation of an initial public offering of the Common Stock
under the Securities Act of 1933, as amended (the "IPO"), the corporation shall

to time by vote of a majority of the directors then in office. Immediately
following the consummation of the IPO, the following provisions shall apply:

1.   NUMBER OF DIRECTORS. The number of directors of this corporation shall
not be less than three. The exact number of directors within the limitations
specified in the preceding sentence shall be fixed from time to time by, or in
the manner provided in, this corporation's by-laws.

2.   CLASSES OF DIRECTORS. The board of directors shall be and is divided
into three classes: Class I, Class II and Class III. No one class shall have
more than one director more than any other class. If a fraction is contained in
the quotient arrived at by dividing the designated number of directors by three,
then, if such fraction is one-third, the extra director shall be a member of
Class II, and if such fraction is two-thirds, one of the extra directors shall
be a member of Class II and one of the extra directors shall be a member of
Class III, unless otherwise provided from time to time by resolution adopted by
the board of directors.

3.   ELECTION OF DIRECTORS. Elections of directors need not be by written
ballot except as and to the extent provided in the by-laws of this corporation.

4.   TERMS OF OFFICE. Except as provided in Section 7 of this Article XI,
each director shall serve for a term ending on the date of the third annual
meeting of the stockholders following the annual meeting at which such director
was elected; PROVIDED, that each initial director in Class I shall serve for a
term ending on the date of the annual meeting of the stockholders in 1999; each
initial director in Class II shall serve for a term ending on the date of the
annual meeting of the stockholders in 1998; and each initial director in Class
III shall serve for a term ending on the date of the annual meeting of the
stockholders in 1997; and PROVIDED FURTHER, that the term of each director shall
be subject to the election and qualification of his successor and to his earlier
death, resignation or removal.

5.   ALLOCATION OF DIRECTORS AMONG CLASSES IN THE EVENT OF INCREASES OR
DECREASES IN THE NUMBER OF DIRECTORS. In the event of any increase or decrease
in the authorized number of directors, (i) each director then serving as such
shall nevertheless continue as a director of the class of which he is a member
and (ii) the newly created or eliminated directorships resulting from such
increase or decrease shall be apportioned by the board of directors among the
three classes of directors so as to ensure that no one class has more than one
director more than any other class. To the extent possible, consistent with the
foregoing rule, any newly created directorships shall be added to those classes
whose terms of office are to expire at the latest dates following such
allocation, and any newly eliminated directorships shall be subtracted from
those classes whose terms of offices are to expire at the earliest dates
following such allocation, unless otherwise provided from time to time by
resolution adopted by the board of directors.

6.   REMOVAL. Directors of this corporation may be removed only for cause by
the affirmative vote of the holders of at least two-thirds of the shares of the
capital stock of this corporation issued and outstanding and entitled to vote
generally in the election of directors cast at a meeting of the stockholders
called for that purpose.

7.   VACANCIES. Any vacancy in the board of directors, however occurring,
including a vacancy resulting from an enlargement of the board, shall be filled
only by a vote of a majority of the directors then in office, although less than
a quorum, or by a sole remaining director. A director elected to fill a vacancy
shall be elected to hold office until the next election of the class for which
such director shall have been chosen, subject to the election and qualification
of his successor and to his earlier death, resignation or removal.

corporation.

meeting is to be held in which case the meeting shall be held at the same hour
on the next succeeding day not a legal holiday) or at such other date and time
as shall be fixed by the Board of Directors or the President and stated in the
notice of the meeting. If no annual meeting is held in accordance with the
foregoing provisions, the Board of Directors shall cause the meeting to be held
as soon thereafter as convenient. If no annual meeting is held in accordance
with the foregoing provisions, a special meeting may be held in lieu of the
annual meeting, and any action taken at that special meeting shall have the same
effect as if it had been taken at the annual meeting, and in such case all
references in these By-Laws to the annual meeting of stockholders shall be
deemed to refer to such special meeting.

     1.3  SPECIAL MEETING. Special meetings of stockholders may be called at any
time by the Chairman of the Board of Directors, the Chief Executive Officer (or,
if there is no Chief Executive Officer, the President) or the Board of
Directors. Business transacted at any special meeting of stockholders shall be
limited to matters relating to the purpose or purposes stated in the notice of
meeting.

     1.4  NOTICE OF MEETINGS. Except as otherwise provided by law, written 
notice of each meeting of stockholders, whether annual or special, shall be
given not less than 10 nor more than 60 days before the date of the meeting to
each stockholder entitled to vote at such meeting. The notices of all meetings
shall state the place, date and hour of the meeting. The notice of a special
meeting shall state, in addition, the purpose or purposes for which the meeting
is called. If mailed, notice is given when deposited in the United States mail,
postage prepaid, directed to the stockholder at his address as it appears on the
records of the corporation.

stockholders, a complete list of the stockholders entitled to vote at the
meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder.
Such list shall be open to the examination of any stockholder, for any purpose
germane to the meeting, during ordinary business hours, for a period of at least
10 days prior to the meeting, at a place within the city where the meeting is to
be held. The list shall also be produced and kept at the time and place of the
meeting during the whole time of the meeting, and may be inspected by any
stockholder who is present.



<PAGE>   5



     1.6  QUORUM. Except as otherwise provided by law, the Certificate of
Incorporation or these By-Laws, the holders of a majority of the shares of the
capital stock of the corporation issued and outstanding and entitled to vote at
the meeting, present in person or represented by proxy, shall constitute a
quorum for the transaction of business.

     1.7  ADJOURNMENTS. Any meeting of stockholders may be adjourned to any 
other time and to any other place at which a meeting of stockholders may be held
under these By-Laws by the stockholders present or represented at the meeting
and entitled to vote, although less than a quorum, or, if no stockholder is
present, by any officer entitled to preside at or to act as Secretary of such
meeting. It shall not be necessary to notify any stockholder of any adjournment
of less than 30 days if the time and place of the adjourned meeting are
announced at the meeting at which adjournment is taken, unless after the
adjournment a new record date is fixed for the adjourned meeting. At the
adjourned meeting, the corporation may transact any business which might have
been transacted at the original meeting.

     1.8  VOTING AND PROXIES. Each stockholder shall have one vote for each 
share of stock entitled to vote held of record by such stockholder and a
proportionate vote for each fractional share so held, unless otherwise provided
by the General Corporation Law of the State of Delaware, the Certificate of
Incorporation or these By-Laws. Each stockholder of record entitled to vote at a
meeting of stockholders may vote or express such consent or dissent in person or
may authorize another person or persons to vote or act for him by written proxy
executed by the stockholder or his authorized agent and delivered to the
Secretary of the corporation. No such proxy shall be voted or acted upon after
three years from the date of its execution, unless the proxy expressly provides
for a longer period.

     1.9  ACTION AT MEETING. When a quorum is present at any meeting, the 
holders of a majority of the stock present or represented and voting on a matter
(or if there are two or more classes of stock entitled to vote as separate
classes, then in the case of each such class, the holders of a majority of the
stock of that class present or represented and voting on a matter) shall decide
any matter to be voted upon by the stockholders at such meeting, except when a
different vote is required by express provision of law, the Certificate of
Incorporation or these By-Laws. Any election by stockholders shall be determined
by a plurality of the votes cast by the stockholders entitled to vote at the
election.

     1.10 NOMINATION OF DIRECTORS. Only persons who are nominated in accordance
with the following procedures shall be eligible for election as directors.
Nomination for election to the Board of Directors of the corporation at a
meeting of stockholders may be made by the Board of Directors or by any
stockholder of the corporation entitled to vote for the election of directors at
such meeting who complies with the notice procedures set forth in this Section
1.10. Such nominations, other than those made by or on behalf of the Board of
Directors, shall be made by notice in writing delivered or mailed by first class
United States mail, postage prepaid, to the Secretary, and received not less
than 60 days, nor more than 90 days prior to such meeting; provided, however,
that if less than 70 days' notice or prior public disclosure of the date of the


                                        2

<PAGE>   6



meeting is given to stockholders, such nomination shall have been mailed or
delivered to the Secretary not later than the close of business on the 10th day
following the date on which the notice of the meeting was mailed or such public
disclosure was made, whichever occurs first. Such notice shall set forth (a) as
to each proposed nominee (i) the name, age, business address and, if known,
residence address of each such nominee, (ii) the principal occupation or
employment of each such nominee, (iii) the number of shares of stock of the
corporation which are beneficially owned by each such nominee, and (iv) any
other information concerning the nominee that must be disclosed as to nominees
in proxy solicitations pursuant to Regulation 14A under the Securities Exchange
Act of 1934, as amended (the "Exchange Act") (including such person's written
consent to be named as a nominee and to serve as a director if elected); and (b)
as to the stockholder giving the notice (i) the name and address, as they appear
on the corporation's books, of such stockholder and (ii) the class and number of
shares of the corporation which are beneficially owned by such stockholder. The
corporation may require any proposed nominee to furnish such other information
as may reasonably be required by the corporation to determine the eligibility of
such proposed nominee to serve as a director of the corporation.

     The chairman of the meeting may, if the facts warrant, determine and
declare to the meeting that a nomination was not made in accordance with the
foregoing procedure, and if he should so determine, he shall so declare to the
meeting and the defective nomination shall be disregarded.

     1.11 NOTICE OF BUSINESS AT ANNUAL MEETINGS. At an annual meeting of the
stockholders, only such business shall be conducted as shall have been properly
brought before the meeting. To be properly brought before an annual meeting,
business must be (i) specified in the notice of meeting (or any supplement
thereto) given by or at the direction of the Board of Directors, (ii) otherwise
properly brought before the meeting by or at the direction of the Board of
Directors, (iii) otherwise properly brought before an annual meeting by a
stockholder. For business to be properly brought before an annual meeting by a
stockholder, if such business relates to the election of directors of the
corporation, the procedures in Section 1.10 must be complied with. If such
business relates to any other matter, the stockholder must have given timely
notice thereof in writing to the Secretary. To be timely, a stockholder's notice
must be delivered to or mailed and received at the principal executive offices
of the corporation not less than 60 days nor more than 90 days prior to the
meeting; PROVIDED, HOWEVER, that in the event that less than 70 days' notice or
prior public disclosure of the date of the meeting is given or made to
stockholders, notice by the stockholder to be timely must be so received not
later than the close of business on the 10th day following the date on which
such notice of the date of the meeting was mailed or such public disclosure was
made, whichever occurs first. A stockholder's notice to the Secretary shall set
forth as to each matter the stockholder proposes to bring before the annual
meeting (i) a brief description of the business desired to be brought before the
annual meeting and the reasons for conducting such business at the annual
meeting, (ii) the name and address, as they appear on the corporation's books,
of the stockholder proposing such business, (iii) the class and number of shares
of the corporation which are beneficially owned by the stockholder, and (iv) any
material interest of the stockholder in such business. Notwithstanding anything
in these By-Laws to the


                                        3

<PAGE>   7



contrary, no business shall be conducted at any annual meeting except in
accordance with the procedures set forth in this Section 1.11 and except that
any stockholder proposal which complies with Rule 14a-8 of the proxy rules (or
any successor provision) promulgated under the Exchange Act, and is to be
included in the corporation's proxy statement for an annual meeting of
stockholders shall be deemed to comply with the requirements of this Section
1.11.

     The chairman of the meeting shall, if the facts warrant, determine and
declare to the meeting that business was not properly brought before the meeting
in accordance with the provisions of this Section 1.11, and if he should so
determine, the chairman shall so declare to the meeting and any such business
not properly brought before the meeting shall not be transacted.

     1.12 ACTION WITHOUT MEETING. At any time during which a class of capital
stock of the corporation is registered under Section 12 of the Exchange Act,
stockholders may not take any action by written consent in lieu of a meeting.

     1.13 ORGANIZATION. The Chairman of the Board, or in his absence the Vice
Chairman of the Board designated by the Chairman of the Board, or the President,
in the order named, shall call meetings of the stockholders to order, and act as
chairman of such meeting; PROVIDED, HOWEVER, that the Board of Directors may
appoint any stockholder to act as chairman of any meeting in the absence of the
Chairman of the Board. The Secretary of the corporation shall act as secretary
at all meetings of the stockholders; but in the absence of the Secretary at any
meeting of the stockholders, the presiding officer may appoint any person to act
as secretary of the meeting.

                              ARTICLE 2 - DIRECTORS
                              ---------------------

     2.1  GENERAL POWERS. The business and affairs of the corporation shall be
managed by or under the direction of a Board of Directors, who may exercise all
of the powers of the corporation except as otherwise provided by law, the
Certificate of Incorporation or these ByLaws. In the event of a vacancy in the
Board of Directors, the remaining directors, except as otherwise provided by
law, may exercise the powers of the full Board until the vacancy is filled.

     2.2  NUMBER; ELECTION AND QUALIFICATION. The number of directors which 
shall constitute the whole Board of Directors shall be determined by resolution
of the Board of Directors, but following the consummation of the Company's
initial public offering of common stock under the Securities Act of 1933 in no
event shall such number of directors be less than three. The number of directors
may be decreased at any time and from time to time by a majority of the
directors then in office, but only to eliminate vacancies existing by reason of
the death, resignation, removal or expiration of the term of one or more
directors. The directors shall be elected at the annual meeting of stockholders
by such stockholders as have the right to vote on such election. Directors need
not be stockholders of the corporation.


                                        4

<PAGE>   8



     2.3  CLASSES OF DIRECTORS. The Board of Directors shall be and is divided
into three classes: Class I, Class II and Class III. No one class shall have
more than one director more than any other class. If a fraction is contained in
the quotient arrived at by dividing the designated number of directors by three,
then, if such fraction is one-third, the extra director shall be a member of
Class II, and if such fraction is two-thirds, one of the extra directors shall
be a member of Class II and one of the extra directors shall be a member of
Class III, unless otherwise provided from time to time by resolution adopted by
the Board of Directors.

     2.4  TERMS OF OFFICE. Except as otherwise provided in the Certificate of
Incorporation or these By-Laws, each director shall serve for a term ending on
the date of the third annual meeting of the stockholders following the annual
meeting of the stockholders at which such director was elected; PROVIDED, that
each initial director in Class I shall serve for a term ending on the date of
the annual meeting of stockholders in 1999; each initial director in Class II
shall serve for a term ending on the date of the annual meeting of stockholders
in 1998; and each initial director in Class III shall serve for a term ending on
the date of the annual meeting of stockholders in 1997; and PROVIDED FURTHER,
that the term of each director shall be subject to the election and
qualification of his successor and to his earlier death, resignation or removal.

     2.5  ALLOCATION OF DIRECTORS AMONG CLASSES IN THE EVENT OF INCREASES OR
DECREASES IN THE NUMBER OF DIRECTORS. In the event of any increase or decrease
in the authorized number of directors, (i) each director then serving as such
shall nevertheless continue as a director of the class of which he is a member
and (ii) the newly created or eliminated directorships resulting from such
increase or decrease shall be apportioned by the Board of Directors among the
three classes of directors so as to ensure that no one class has more than one
director more than any other class. To the extent possible, consistent with the
foregoing rule, any newly created directorships shall be added to those classes
whose terms of office are to expire at the latest dates following such
allocation, and any newly eliminated directorships shall be subtracted from
those classes whose terms of offices are to expire at the earliest dates
following such allocation, unless otherwise provided from time to time by
resolution adopted by the Board of Directors.

     2.6  VACANCIES. Any vacancy in the Board of Directors, however occurring,
including a vacancy resulting from an enlargement of the Board, shall be filled
only by vote of a majority of the directors then in office, although less than a
quorum, or by a sole remaining director. A director elected to fill a vacancy
shall be elected for the unexpired term of his predecessor in office, and a
director chosen to fill a position resulting from an increase in the number of
directors shall hold office until the next election of the class for which such
director shall have been chosen, subject to the election and qualification of
his successor and to his earlier death, resignation or removal.

     2.7  RESIGNATION. Any director may resign by delivering his written
resignation to the corporation at its principal office or to the President or
Secretary. Such resignation shall be effective upon receipt unless it is
specified to be effective at some other time or upon the happening of some other
event.

     2.8  REGULAR MEETINGS. Regular meetings of the Board of Directors may be
held without notice at such time and place, either within or without the State
of Delaware, as shall be determined from time to time by the Board of Directors;
PROVIDED, that any director who is absent when such a determination is made
shall be given notice of the determination. A regular meeting of the Board of
Directors may be held without notice immediately after and at the same place as
the annual meeting of stockholders.

     2.9  SPECIAL MEETINGS. Special meetings of the Board of Directors may be
held at any time and place, within or without the State of Delaware, designated
in a call by the Chairman of the Board, President, one-third or more in number
of the Directors, or by one director in the event that there is only a single
director in office.

     2.10 NOTICE OF SPECIAL MEETINGS. Notice of any special meeting of directors
shall be given to each director by the Secretary or by the officer or one of the
directors calling the meeting. Notice shall be duly given to each director (i)
by giving notice to such director in person or by telephone at least 24 hours in
advance of the meeting, (ii) by sending a telegram, telecopy, or telex, or
delivering written notice by hand, to his last known business or home address at
least 24 hours in advance of the meeting, or (iii) by mailing written notice to
his last known business or home address at least 72 hours in advance of the
meeting. A notice or waiver of notice of a special meeting of the Board of
Directors need not specify the purposes of the meeting.

     2.11 MEETINGS BY TELEPHONE CONFERENCE CALLS. Directors or any members of
any committee designated by the directors may participate in a meeting of the
Board of Directors or such committee by means of conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other, and participation by such means shall constitute
presence in person at such meeting.

     2.12 QUORUM. A majority of the total number of the whole Board of Directors
shall constitute a quorum at all meetings of the Board of Directors. In the
event one or more of the directors shall be disqualified to vote at any meeting,
then the required quorum shall be reduced by one for each such director so
disqualified; PROVIDED, HOWEVER, that in no case shall less than one-third (1/3)
of the number of directors so fixed pursuant to Section 2.2 constitute a quorum.
In the absence of a quorum at any such meeting, a majority of the directors
present may adjourn the meeting from time to time without further notice, other
than announcement at the meeting, until a quorum shall be present.

     2.13 ACTION AT MEETING. At any meeting of the Board of Directors at which a
quorum is present, the vote of a majority of those present shall be sufficient
to take any action, unless a greater number is required by law, the Certificate
of Incorporation or these By-Laws.

     2.14 ACTION BY CONSENT. Any action required or permitted to be taken at any
meeting of the Board of Directors or of any committee of the Board of Directors
may be taken without a meeting, if all members of the Board or committee, as the
case may be, consent to the action in


                                        6

<PAGE>   10



writing, and the written consents are filed with the minutes of proceedings of
the Board or committee.

     2.15 REMOVAL. Directors of the corporation may be removed only for cause by
the affirmative vote of the holders of two-thirds of the shares of the capital
stock of the corporation issued and outstanding and entitled to vote generally
in the election of directors at a meeting of the stockholders called for that
purpose.

     2.16 COMMITTEES. The Board of Directors may, by resolution passed by a
majority of the whole Board, designate one or more committees, each committee to
consist of one or more of the directors of the corporation. The Board may
designate one or more directors as alternate members of any committee, who may
replace any absent or disqualified member at any meeting of the committee. In
the absence or disqualification of a member of a committee, the member or
members of the committee present at any meeting and not disqualified from
voting, whether or not he or they constitute a quorum, may unanimously appoint
another member of the Board of Directors to act at the meeting in the place of
any such absent or disqualified member. Any such committee, to the extent
provided in the resolution of the Board of Directors and subject to the
provisions of the General Corporation Law of the State of Delaware, shall have
and may exercise all the powers and authority of the Board of Directors in the
management of the business and affairs of the corporation and may authorize the
seal of the corporation to be affixed to all papers which may require it. Each
such committee shall keep minutes and make such reports as the Board of
Directors may from time to time request. Except as the Board of Directors may
otherwise determine, any committee may make rules for the conduct of its
business, but unless otherwise provided by the directors or in such rules, its
business shall be conducted as nearly as possible in the same manner as is
provided in these By-Laws for the Board of Directors.

     2.17 COMPENSATION OF DIRECTORS. Directors may be paid such compensation for
their services and such reimbursement for expenses of attendance at meetings as
the Board of Directors may from time to time determine. No such payment shall
preclude any director from serving the corporation or any of its parent or
subsidiary corporations in any other capacity and receiving compensation for
such service.

                              ARTICLE 3 - OFFICERS

vote choosing or appointing him, or until his earlier death, resignation or
removal.

     3.5  RESIGNATION AND REMOVAL. Any officer may resign by delivering his
written resignation to the corporation at its principal office or to the
President or Secretary. Such resignation shall be effective upon receipt unless
it is specified to be effective at some other time or upon the happening of some
other event. The Board of Directors may remove any officer at any time, with or
without cause.

     3.6  VACANCIES. The Board of Directors may fill any vacancy occurring in 
any office for any reason and may, in its discretion, leave unfilled for such
period as it may determine any offices other than those of President, Treasurer
and Secretary. Each such successor shall hold office for the unexpired term of
his predecessor and until his successor is elected and qualified, or until his
earlier death, resignation or removal.

     3.7  CHAIRMAN OF THE BOARD AND VICE CHAIRMAN OF THE BOARD. The Board of
Directors may appoint a Chairman of the Board. If the Board of Directors
appoints a Chairman of the Board, he shall perform such duties and possess such
powers as are assigned to him by the Board of Directors. If the Board of
Directors appoints a Vice Chairman of the Board, he shall, in the absence or
disability of the Chairman of the Board, perform the duties and exercise the
powers of the Chairman of the Board and shall perform such other duties and
possess such other powers as may from time to time be vested in him by the Board
of Directors.

of Directors, have general charge and supervision of the business of the
corporation. Unless otherwise provided by the Board of Directors, he shall
preside at all meetings of the stockholders and, if he is a director, at all
meetings of the Board of Directors. Unless the Board of Directors has designated

Directors may from time to time prescribe.

Forrester Research, Inc.

Cambridge, Massachusetts 02138

Ladies and Gentlemen:

     This opinion is furnished to you in connection with a registration
statement on Form S-1 (the "Registration Statement"), filed with the Securities
and Exchange Commission (the "Commission") under the Securities Act of 1933, as
amended, for the registration of 2,300,000 shares of Common Stock, $.01 par
value (the "Shares"), of Forrester Research, Inc., a Delaware corporation (the
"Company"). The Shares are to be sold pursuant to an underwriting agreement (the
"Underwriting Agreement") to be entered into among the Company and Goldman,
Sachs & Co. and Robertson, Stephens & Company LLP, as representatives of the
several underwriters named in Schedule I to the Underwriting Agreement.

     We have acted as counsel for the Company in connection with the issue and
sale by the Company of the Shares. For purposes of our opinion, we have examined
and relied upon such documents, records, certificates and other instruments as
we have deemed necessary.

     We express no opinion as to the applicability of compliance with or effect
of Federal law of the law of any jurisdiction other than The Commonwealth of
Massachusetts and the General Corporation Law of the State of Delaware (the
"Delaware General Corporation Law").

     Based upon the foregoing, we are of the opinion that upon the filing with
the Secretary of State of the State of Delaware of the Company's Restated
Certificate of Incorporation in the form approved by the Company's Board of
Directors (the "Restated Certificate") and the sole stockholder of the Company,
the Shares will have been duly authorized and, when issued and

sold by the Company in accordance with the terms of the Underwriting Agreement,
will be validly issued, fully paid and nonassessable.

     We hereby consent to the filing of this opinion as part of the Registration
Statement and to the use of our name therein and in the related prospectus under
the caption "Validity of Shares."

     This opinion is to be used only in connection with the offer and sale of
the Shares while the Registration Statement is in effect.


                                            Very truly yours,

                                            /s/ Ropes & Gray

                          TAX INDEMNIFICATION AGREEMENT


     This TAX INDEMNIFICATION AGREEMENT, dated as of this __ day of ____, 1996,
is entered into by Forrester Research, Inc., a Delaware corporation (the
"Company") and George F. Colony (the "Stockholder").

                                    RECITALS

     WHEREAS, the Stockholder holds all of the outstanding shares of the
     Company's Common Stock, par value $.01, per share (the "Common Stock").

     WHEREAS, the Company has elected to be taxed as S corporation under the
     Code.

     WHEREAS, the Company is now contemplating offering and selling shares of
     its Common Stock to the public (the "Public Offering").

     WHEREAS the Company plans, just prior to the completion of the Public
     Offering, to terminate its S corporation election.

     WHEREAS, after the termination of the Company's S corporation election, the
     Stockholder will continue to be liable for his own federal, state, and
     local income taxes on the Company's Tax Items that pass through to the
     Stockholder under the provisions of Subchapter S of the Code and any
     similar provisions of state and local law for all periods prior to the time
     the Company ceases to be an S Corporation. The Company will be subject to a
     corporate level tax under Subchapter C of the Code and certain state and
     local taxing statutes for periods thereafter. The purpose of this Agreement
     is to set forth the agreement of the Company and the Stockholder with
     respect to certain adjustments to the federal, state, and local personal
     income tax liability of the Stockholder attributable to Tax Items of the
     Company that pass through to the Stockholder under the provisions of
     Subchapter S of the Code and any similar provisions of state and local law
     for periods during which the Company is an S Corporation.

     claim for refund;

          (ii) a decision, judgment, decree, or other order by a court of

Tax Liability arising from an Adjustment with respect to a Tax Item of the
Company.
