                               PROSPECTUS SUMMARY

     This summary highlights only some of the information in this prospectus.
You should read the entire prospectus carefully. Unless otherwise indicated, the
information in this prospectus assumes that the underwriters will not exercise
their over-allotment option.

                     CHARLES RIVER ASSOCIATES INCORPORATED

     Charles River Associates Incorporated is a leading economic and business
consulting firm founded in 1965 that applies advanced analytic techniques and
in-depth industry knowledge to complex engagements for a broad range of clients.
We provide original and authoritative advice for clients involved in many
high-stakes matters, such as multi-billion dollar acquisitions, new product
introductions, major capital investment decisions and complex litigation.

     Businesses are operating in an increasingly complex environment. Companies
must constantly gather, analyze and use available information to enhance their
business strategies and operational efficiencies. The increasing complexity and
changing nature of the business environment is also forcing governments to
modify their regulatory strategies. As a result, businesses and governments are
increasingly relying on sophisticated economic and financial analysis to solve
complex problems and improve decision-making. Furthermore, corporate litigation
has also become more complicated, protracted, expensive and important to the
parties involved. Companies and governments are consequently turning to outside
consultants for access to the specialized expertise, experience and prestige
that are not available to them internally.

     We offer two types of services that help companies respond to this changing
environment: legal and regulatory consulting and business consulting. Through
our legal and regulatory consulting practice, we provide law firms and
businesses involved in litigation and regulatory proceedings with expert advice
on highly technical issues. Through our business consulting practice, we provide
services directly to companies seeking assistance with strategic issues that
require expertise in economics, finance and business analysis. For example, we
provide advice on the following issues:

    - measurement of market share and market    - valuation of intellectual property and

</TABLE>

     We combine expertise in advanced economic and financial methods with
in-depth knowledge of particular industries, such as chemicals, electric power
and other energies, healthcare, materials, media and telecommunications, retail
and wholesale distribution, and transportation.

     We have a highly credentialed and experienced staff of employee
consultants. As of July 31, 1999, we employed 185 full-time professional
consultants, including 60 consultants with Ph.D.s and 39 consultants with other
advanced degrees. Our consultants have backgrounds in a wide range of
disciplines, including economics, business, corporate finance, materials
sciences and engineering. We are extremely selective in our hiring, recruiting
individuals from leading universities, industry and government. Many of our
consultants are nationally recognized as experts in their fields. To enhance our
expertise, we also maintain close working relationships with over 40 renowned
academic and industry experts, whom we call outside experts. We have exclusive
relationships with 13 of these outside experts.

     We have completed more than 3,200 engagements for clients, including major
law firms, corporations, government agencies, foreign governments, utilities,
and national and international trade associations. During our last three fiscal
years, we had over 1,400 engagements for clients that included 63 of the 100
largest U.S. law firms, ranked by The American Lawyer based on 1998 revenues,
and 89 Fortune 500 companies, based on 1998 revenues. During that period, our
clients included Cravath, Swaine & Moore; Ford Motor

Company; Jones, Day, Reavis & Pogue; Procter & Gamble Company Inc.; Skadden,
Arps, Slate, Meagher & Flom LLP; and Time Warner Inc.

     Since our initial public offering in April 1998, we have acquired The
Tilden Group, LLC and Financial Economic Consulting. Both companies add
well-known economists whose specialties strengthen and expand our consulting
capabilities as well as our geographic scope. In addition, we have opened
offices in Toronto, Ontario and Los Angeles, California and have staffed both
offices with leading economists and outside experts.

     Our revenues and income from operations have increased from $37.4 million
and $3.7 million in fiscal 1996 to $53.0 million and $9.3 million in fiscal
1998, representing compound annual growth rates of 19.1% and 58.1%. Our revenues
and income from operations have increased from $22.7 million and $4.0 million in
the first twenty-four weeks of fiscal 1998 to $31.2 million and $5.9 million in
the first twenty-four weeks of fiscal 1999, representing period-to-period
increases of 37.3% and 48.9%.

     Our growth strategy is to:

     - attract and retain high quality consultants as employees;

     - increase our marketing activities to attract new clients and increase the
       overall exposure of our employee consultants;

     - expand our services and expertise into related areas of business;

     - establish relationships with additional outside experts; and

     - pursue strategic acquisitions and alliances in order to gain access to
       additional consultants, new service offerings, additional industry
       expertise, a broader client base and offices in new geographic locations.

     Our principal executive offices are located at 200 Clarendon Street,
Boston, Massachusetts 02116 and our telephone number is (617) 425-3000.

                                  RISK FACTORS

     An investment in our common stock involves a high degree of risk. You
should carefully consider the following risk factors in evaluating our business
before purchasing any of our common stock. If any of these risks, or other risks
not presently known to us or that we currently believe are not significant,
develops into an actual event, then our business, financial condition and
results of operations could be adversely affected. If that happens, the market
price of our common stock could decline, and you may lose all or part of your
investment.

WE DEPEND UPON ONLY A FEW KEY EMPLOYEES TO GENERATE REVENUES

     Our business consists primarily of the delivery of professional services
and, accordingly, our success depends heavily on the efforts, abilities,
business generation capabilities and project execution of our employee
consultants. If we lose the services of any consultant or if our consultants
fail to generate business or otherwise fail to perform effectively, that could
have a material adverse effect on our business, financial condition and results
of operations. Our consultants generated engagements that accounted for
approximately 79% of our revenues in each of fiscal 1997 and fiscal 1998. Our
top five consultants in each of fiscal 1997 and fiscal 1998 generated
approximately 33% of our revenues in those years. We do not have any employment
or non-competition agreements with our consultants. Each consultant can
terminate his or her relationship with us at will and without notice and can
begin to compete with us at any time.

OUR BUSINESS COULD SUFFER IF WE ARE UNABLE TO HIRE ADDITIONAL QUALIFIED
CONSULTANTS AS EMPLOYEES

     We must hire increasing numbers of highly qualified, highly educated
consultants as employees. Our failure to recruit and retain a significant number
of qualified consultants could have a material adverse effect on our business,
financial condition and results of operations. Relatively few potential
employees meet our hiring criteria, and we face significant competition for
these employees from our direct competitors, academic institutions, government
agencies, research firms, investment banking firms and other enterprises. Many
of these competing employers are able to offer potential employees significantly
greater compensation and benefits or more attractive lifestyle choices, career
paths or geographic locations than we can. Increasing competition for these
consultants may also significantly increase our labor costs, which could have a
material adverse effect on our margins and results of operations.

OUR FAILURE TO MANAGE OUR EXPANDING BUSINESS SUCCESSFULLY COULD ADVERSELY AFFECT
OUR REVENUES AND RESULTS OF OPERATIONS

     Any failure on our part to manage growth successfully could have a material
adverse effect on our business, financial condition and results of operations.
We have been experiencing significant growth in our revenues and employee base
as a result of both internal growth and acquisitions. This growth creates new
and increased management, consulting and training responsibilities for our
employee consultants. This growth also increases the demands on our internal
systems, procedures and controls, and on our managerial, administrative,
financial, marketing and other resources. We depend heavily upon the managerial,
operational and administrative skills of our officers, particularly James C.
Burrows, our President and Chief Executive Officer, to manage this growth. New
responsibilities and demands may adversely affect the overall quality of our
work. No member of our management team has experience in managing a public
company other than CRA. We have also recently opened offices in new geographic
locations and may open additional offices in the future. Opening new offices may
entail substantial start-up and maintenance costs.

WE DEPEND ON OUR OUTSIDE EXPERTS

     We depend on our existing relationships with our exclusive outside experts.
Four of our exclusive outside experts generated engagements that accounted for
approximately 18% of our revenues in fiscal 1997, and six outside experts
generated engagements that accounted for approximately 19% of our revenues in
fiscal 1998. We believe that these outside experts are highly regarded in their
fields and that each offers a combination of knowledge, experience and expertise
that would be very difficult to replace. We also believe that we have

                                        6
<PAGE>   8

been able to secure some engagements and attract consultants in part because we
could offer the services of these outside experts. Most of these outside experts
can limit their relationships with us at any time for any reason. These reasons
could include affiliations with universities whose policies prohibit accepting
specified engagements, the pursuit of other interests and retirement. Thirteen
of our approximately 40 outside experts have entered agreements with us that
restrict their right to compete with us. The limitation or termination of any of
their relationships with us or competition from any of them following the
termination of their non-competition agreements with us could have a material
adverse effect on our business, financial condition and results of operations.

     To meet our long-term growth targets, we also need to establish ongoing
relationships with additional outside experts that have reputations as leading
experts in their fields. We may be unable to establish relationships with any
additional outside experts. In addition, any relationship that we do establish
may not help us meet our objectives or generate the revenues or earnings that we
anticipate.

FLUCTUATIONS IN OUR QUARTERLY REVENUES AND RESULTS OF OPERATIONS COULD DEPRESS
THE MARKET PRICE
OF OUR COMMON STOCK

     We may experience significant fluctuations in our revenues and results of
operations from one quarter to the next. If our revenues or net income in a
quarter fall below the expectations of securities analysts or investors, the
market price of our common stock could fall significantly. Our results of
operations in any quarter can fluctuate for many reasons, including the
following:

     - the number of weeks in the quarter

     - the number, scope and timing of ongoing client engagements

     - the extent to which we can reassign employee consultants efficiently from
       one engagement to the next

     - employee hiring

     - the extent of discounting or cost overruns

     - severe weather conditions and other factors affecting employee
       productivity.

Because we generate almost all of our revenues from consulting services that we
provide on an hourly-fee basis, our revenues in any period are directly related
to the number of our employee consultants, their billing rates and the number of
billable hours they work in that period. We have a limited ability to increase
any of these factors in the short term. Accordingly, if we underutilize our
consultants during one part of a fiscal period, we may be unable to compensate
by augmenting revenues during another part of that period. In addition, we may
be unable to fully utilize the additional consultants that we intend to hire,
particularly in the quarter in which we hire them. Moreover, a significant
majority of our operating expenses, primarily office rent and salaries, are
fixed in the short term. As a result, if our revenues fail to meet our
projections in any quarter, that could have a disproportionate adverse effect on
our net income. For these reasons, we believe that you should not rely on our
historical results of operations as an indication of our future performance.

ACQUISITIONS MAY DISRUPT OUR OPERATIONS OR ADVERSELY AFFECT OUR RESULTS

     We may seek to acquire other businesses, and we may be unable to identify,
acquire, successfully integrate or profitably manage any business without
substantial expense, delay or other operational or financial problems. In
addition, we may be unable to achieve the financial, operational and other
benefits we anticipate from any acquisition. In December 1998 we acquired The
Tilden Group and in February 1999 we acquired Financial Economic Consulting.
Before these recent acquisitions, we had never acquired another business. We may
be unable to manage these companies profitably or successfully integrate their
operations with our own. Competition for future acquisition opportunities in our
markets could increase the price we pay for businesses

                                        7
<PAGE>   9

we acquire and could reduce the number of potential acquisition targets.
Further, acquisitions may involve a number of special risks, such as:

     - one-time charges related to the acquisition

     - diversion of our management's time, attention and resources

     - loss of key acquired personnel

     - increased costs to improve or coordinate managerial, operational,
       financial and administrative systems

     - dilutive issuances of equity securities

     - the assumption of legal liabilities

     - amortization of acquired intangible assets

     - difficulties in integrating diverse corporate cultures

     - additional conflicts of interests.

The occurrence of any of these events could have a material adverse effect on
our business, financial condition and results of operations.

MAINTAINING OUR PROFESSIONAL REPUTATION IS CRUCIAL TO OUR FUTURE SUCCESS

     Our ability to secure new engagements and hire qualified consultants as
employees depends heavily on our overall reputation as well as the individual
reputations of our consultants and principal outside experts. Because we obtain
a majority of our new engagements from existing clients or from referrals by
those clients, any client that is dissatisfied with our performance on a single
matter could seriously impair our ability to secure new engagements. Any factor
that diminishes our reputation or the reputations of any of our personnel or
outside experts could make it substantially more difficult for us to compete
successfully for both new engagements and qualified consultants. That could have
a material adverse effect on our business, financial condition and results of
operations.

WE DEPEND ON OUR ANTITRUST AND MERGERS AND ACQUISITIONS CONSULTING BUSINESS

     We derived approximately 36% of our revenues in fiscal 1996, 35% in fiscal
1997 and 48% in fiscal 1998 from engagements in our antitrust and mergers and
acquisitions practice areas. Any substantial reduction in the number of our
engagements in these practice areas could have a material adverse effect on our
business, financial condition and results of operations. We derived almost all
of these revenues from engagements relating to enforcement of United States
antitrust laws. Changes in federal antitrust laws, changes in judicial
interpretations of these laws or less vigorous enforcement of these laws as a
result of changes in political appointments or priorities or for other reasons
could substantially reduce our revenues from engagements in this area. In
addition, adverse changes in general economic conditions, particularly
conditions influencing the merger and acquisition activity of larger companies,
could also adversely impact engagements in which we assist clients in
proceedings before the Department of Justice and the Federal Trade Commission.

OUR REVENUES COME FROM A LIMITED NUMBER OF LARGE ENGAGEMENTS

     We have been deriving a significant portion of our revenues from a limited
number of large engagements. If we do not obtain a significant number of new
large engagements each year, our business, financial condition and results of
operations could suffer. Our ten largest engagements accounted for approximately
28% of our revenues in fiscal 1996, 23% in fiscal 1997 and 29% in fiscal 1998.
Our ten largest clients accounted for approximately 42%, 29% and 38% of our
revenues in those years. In general, the volume of work we perform for any
particular client varies from year to year, and a major client in one year may
not hire us again.

                                        8
<PAGE>   10

CLIENTS CAN TERMINATE ENGAGEMENTS WITH US AT ANY TIME

     Our engagements generally depend upon disputes, proceedings or transactions
that involve our clients. Our clients may decide at any time to seek to resolve
the dispute or proceeding or abandon the transaction. Our engagements can
therefore terminate suddenly and without advance notice to us. If an engagement
is terminated unexpectedly, the employee consultants working on the engagement
could be underutilized until we assign them to other projects. Accordingly, the
termination or significant reduction in the scope of a single large engagement
could have a material adverse effect on our business, financial condition and
results of operations.

POTENTIAL CONFLICTS OF INTERESTS MAY PRECLUDE US FROM ACCEPTING SOME ENGAGEMENTS

     We provide our services primarily in connection with significant or complex
transactions, disputes or other matters that are usually adversarial or that
involve sensitive client information. Our engagement by a client frequently
precludes us from accepting engagements with the client's competitors or
adversaries because of conflicts between their interests or positions on
disputed issues or other reasons. Accordingly, the number of both potential
clients and potential engagements is limited. Moreover, in many industries in
which we provide consulting services, particularly in the telecommunications
industry, there has been a continuing trend toward business consolidations and
strategic alliances. These consolidations and alliances reduce the number of
potential clients for our services and increase the chances that we will be
unable to continue some of our ongoing engagements or accept new engagements as
a result of conflicts of interests. Any such result could have a material
adverse effect on our business, financial condition and results of operations.

INTENSE COMPETITION FROM OTHER ECONOMIC AND BUSINESS CONSULTING FIRMS COULD HURT
OUR BUSINESS

     The market for economic and business consulting services is intensely
competitive, highly fragmented and subject to rapid change. We may be unable to
compete successfully with our existing competitors or with any new competitors.
In general, there are few barriers to entry into our markets, and we expect to
face additional competition from new entrants into the economic and business
consulting industries. In the legal and regulatory consulting market, we compete
primarily with other economic consulting firms and individual academics. In the
business consulting market, we compete primarily with other business and
management consulting firms, specialized or industry-specific consulting firms,
the consulting practices of large accounting firms, and the internal
professional resources of existing and potential clients. Many of our
competitors have national and international reputations as well as significantly
greater personnel, financial, managerial, technical and marketing resources than
we do. Some of our competitors also have a significantly broader geographic
presence than we do.

OUR ENTRY INTO NEW LINES OF BUSINESS COULD ADVERSELY AFFECT OUR RESULTS OF
OPERATIONS

     If we attempt to develop new practice areas or lines of business outside
our core economic and business consulting services, that effort could have a
material adverse effect on our results of operations. For example, in June 1997,
we established and purchased a controlling interest in NeuCo LLC, which provides
applications consulting services and a family of neural network software
solutions and complementary applications for fossil-fired electric utilities.
NeuCo has not been and may never be profitable. Our efforts in new practice
areas or new lines of business involve inherent risks, including risks
associated with inexperience and competition from mature participants in the
markets we enter. Our inexperience may result in costly decisions that could
have a material adverse effect on our business, financial condition and results
of operations.

OUR ENGAGEMENTS MAY RESULT IN PROFESSIONAL LIABILITY

     Our services typically involve difficult analytical assignments and carry
risks of professional and other liability. Many of our engagements involve
matters that could have a severe impact on the client's business, cause the
client to lose significant amounts of money or prevent the client from pursuing
desirable business opportunities. Accordingly, if a client is dissatisfied with
our performance, the client could threaten or bring litigation in order to
recover damages or to contest its obligation to pay our fees. Litigation
alleging that we

                                        9
<PAGE>   11

performed negligently or otherwise breached our obligations to the client could
expose us to significant liabilities and tarnish our reputation. These outcomes
could have a material adverse effect on our business, financial condition and
results of operations.

"YEAR 2000" PROBLEMS MAY DISRUPT OUR OPERATIONS

     Many existing computer systems and software products do not properly
recognize dates after December 31, 1999. This "Year 2000" problem could result
in system failures or miscalculations causing disruptions of operations. The
inability of products, services and systems on which we rely to process dates
after December 31, 1999 could seriously harm our business.

     We have conducted tests and sought confirmation from our software vendors
to determine whether the software we use is Year 2000 compliant. Based on the
results of our investigation, we believe that all of our internal software
systems are Year 2000 compliant, except for our time-keeping and billing
software. We are planning to replace our time-keeping and billing software with
software that is Year 2000 compliant in the second half of calendar 1999.
However, we may experience delays in implementing the replacement software,
which could disrupt our operations, create delays in billing our clients and
require us to spend significant amounts of money to correct the problem.
Moreover, we may discover undetected Year 2000 errors or defects in our other
internal software systems and, if such errors or defects are discovered, the
costs of making such systems Year 2000 compliant could have a material adverse
effect on our business, financial condition and results of operations.

     We rely on third-party vendors that may not be Year 2000 compliant for some
of our equipment and services. To date, we have not conducted a Year 2000 review
of all of our vendors. Failure of systems maintained by our vendors to operate
properly with regard to the Year 2000 and thereafter could require us to incur
significant unanticipated expenses to remedy any problems or replace affected
vendors and could have a material adverse effect on our business, financial
condition and results of operations.

WE WILL HAVE BROAD DISCRETION IN USING THE PROCEEDS OF THIS OFFERING

     We intend to use all of our proceeds from this offering for working capital
and general corporate purposes, including potential acquisitions. Accordingly,
we will have broad discretion in using our proceeds. You will not have the
opportunity to evaluate the economic, financial or other information that we
will use to determine how to use our proceeds.

THE PRICE OF OUR COMMON STOCK MAY BE VOLATILE

     Many factors may cause the market price of our common stock to fluctuate
significantly, including the following:

     - variations in our quarterly results of operations

     - the hiring or departure of key personnel or outside experts

     - changes in our professional reputation

     - the introduction of new services by us or our competitors

     - acquisitions or strategic alliances involving us or our competitors

     - changes in accounting principles

     - changes in the legal and regulatory environment affecting clients

     - changes in estimates of our performance or recommendations by securities
       analysts

     - future sales of shares of common stock in the public market

     - market conditions in the industry and the economy as a whole.

                                       10
<PAGE>   12

In addition, the stock market has recently experienced extreme price and volume
fluctuations. These fluctuations are often unrelated to the operating
performance of particular companies. These broad market fluctuations may
adversely affect the market price of our common stock. When the market price of
a company's stock drops significantly, stockholders often institute securities
class action litigation against the company. Any such litigation against us
could cause us to incur substantial costs and could divert the time and
attention of our management and other resources. Any of these events could have
a material adverse effect on our business, financial condition and results of
operations.

OUR CHARTER AND BY-LAWS AND MASSACHUSETTS LAW MAY DETER TAKE-OVERS

     Our articles of organization and by-laws and Massachusetts law contain
provisions that could have anti-takeover effects and that could discourage,
delay or prevent a change in control of CRA or an acquisition of CRA at a price
that many stockholders may find attractive. These provisions may also discourage
proxy contests and make it more difficult for stockholders of CRA to take some
corporate actions, including the election of directors. The existence of these
provisions could limit the price that investors might be willing to pay in the
future for shares of our common stock.

                           FORWARD-LOOKING STATEMENTS

     Statements in this prospectus or in the documents we incorporate by
reference that are not purely historical, such as statements regarding our
expectations, beliefs, estimates, intentions, plans and strategies regarding the
future, are forward-looking statements. These statements are only predictions,
and they involve risks, uncertainties and assumptions that could cause our
actual results to differ materially from the results we express in the
forward-looking statements. The sections entitled "Risk Factors," "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
"Business" include important factors that could cause or contribute to these
differences. We cannot guarantee the results expressed in any forward-looking
statement, and accordingly you should not place undue reliance on these
statements. We have based all forward-looking statements on information
available to us on the date of this prospectus, and we have no obligation to
update any forward-looking statement.

                                USE OF PROCEEDS

     CRA estimates that its net proceeds from the sale of the 200,000 shares of
common stock it is offering will be approximately $5.0 million, after deducting
the estimated underwriting discounts and commissions and estimated offering
expenses payable by CRA and assuming a public offering price of $28.125 per
share.

     CRA intends to use its net proceeds from the offering for general corporate
purposes, including working capital and possible acquisitions of and investments
in complementary businesses. CRA currently has no agreement or understanding
regarding any acquisition or investment. Pending these uses, CRA intends to
invest its net proceeds from the offering in investment-grade, short-term,
interest-bearing instruments. CRA will not receive any proceeds from the sale of
shares of common stock by the selling stockholders. For risks associated with
our use of proceeds, see "Risk Factors -- We will have broad discretion in using
the proceeds of this offering."

                PRICE RANGE OF COMMON STOCK AND DIVIDEND POLICY

     CRA first offered its common stock to the public on April 23, 1998. Since
that time, the common stock has been quoted on the Nasdaq National Market under
the symbol CRAI. The following table sets forth, for the periods indicated, the
high and low closing sale prices for the common stock as reported on the Nasdaq

     On August 24, 1999, the closing sale price of the common stock as reported
on the Nasdaq National Market was $28.125 per share. On that date, CRA had
approximately 57 holders of record of the common stock. This number does not
include stockholders for whom shares were held in a "nominee" or "street" name.

     Before its initial public offering on April 23, 1998, CRA made periodic
distributions to its stockholders in amounts equal to their aggregate tax
liabilities associated with CRA's taxable earnings as an S corporation
attributable to them, as well as other dividend distributions.

     CRA currently intends to retain any future earnings to finance its
operations and therefore does not anticipate paying any cash dividends in the
foreseeable future. In addition, the terms of CRA's bank line of credit place
restrictions on CRA's ability to pay cash dividends on its common stock.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

     CRA is a leading economic and business consulting firm that applies
advanced analytic techniques and in-depth industry knowledge to complex
engagements for a broad range of clients. Founded in 1965, CRA provides original
and authoritative advice for clients involved in many high-stakes matters, such
as multi-billion dollar acquisitions, new product introductions, major capital
investment decisions and complex litigation. CRA offers two types of services:
legal and regulatory consulting and business consulting. CRA estimates that it
derived approximately 70% of its revenues in fiscal 1998 from legal and
regulatory consulting and approximately 30% from business consulting.

     CRA derives revenues principally from professional services rendered by its
employee consultants. In most instances, CRA charges clients on a
time-and-materials basis and recognizes revenues in the period when CRA provides
its services. CRA charges consultants' time at hourly rates, which vary from
consultant to consultant depending on a consultant's position, experience and
expertise, and other factors. Outside experts may or may not bill clients
directly for their services. As a result, CRA generates substantially all of its
professional services fees from the work of its own full-time consultants.
Factors that affect CRA's professional services fees include the number and
scope of client engagements, the number of consultants employed by CRA, the
consultants' billing rates, and the number of hours worked by the consultants.
In addition to professional services fees, a portion of CRA's revenues
represents expenses billed to clients, such as travel and other out-of-pocket
expenses, charges for support staff and outside contractors, and other
reimbursable expenses.

     CRA's costs of services include the salaries, bonuses and benefits of CRA's
employee consultants. CRA currently has one bonus program. This program awards
discretionary bonuses based on CRA's revenues and profitability and individual
performance. During fiscal 1995, fiscal 1996 and fiscal 1997, CRA also had
another bonus program, which consisted of discretionary payments to officers and
selected outside experts based primarily on CRA's cash flows. These bonus
payments are shown as "supplemental compensation" in CRA's statements of income.
CRA discontinued this bonus program after fiscal 1997. Costs of services also
include out-of-pocket and other expenses that are billed to clients, and the
salaries, bonuses and benefits of support staff whose time is billed directly to
clients, such as librarians, editors and computer programmers. CRA's gross
profit, which equals revenues less costs of services and supplemental
compensation, is affected by changes in the mix of revenues. CRA experiences
significantly higher gross margins on revenues from professional services fees
than on revenues from expenses billed to clients. General and administrative
expenses include salaries, bonuses and benefits of CRA's administrative and
support staff, bonuses to outside experts for generating new business, office
rent, and marketing and other costs.

     In June 1997, CRA invested approximately $650,000 for a majority interest
in NeuCo LLC. NeuCo was established by CRA and an affiliate of Commonwealth
Energy Systems as a start-up entity to develop and market a family of neural
network software tools and complementary applications consulting services for
electric utilities. CRA's financial statements are consolidated with the
financial statements of NeuCo. NeuCo sustained net losses after taxes of
approximately $564,000 in the period from inception (June 19, 1997) to November
29, 1997, $619,000 in fiscal 1998 and $238,000 in the twenty-four weeks ended
May 14, 1999. NeuCo may never become profitable. The portion of this loss
allocable to NeuCo's minority owners is shown as "minority interest" in CRA's
statements of income, and that amount, together with the capital contributions
to NeuCo of its minority owners, is shown as "minority interest" in CRA's
balance sheets. In addition, in December 1998, CRA loaned NeuCo $370,000 and the
affiliate of Commonwealth Energy Systems loaned NeuCo $130,000. The amount owed
to the affiliate of Commonwealth Energy Systems is shown as "note payable to
minority interest holder" in CRA's balance sheets.

     On December 15, 1998, CRA acquired assets and assumed specified liabilities
of The Tilden Group for an aggregate of $9.6 million in cash and common stock.
CRA acquired accounts receivable, work in process, fixed assets and the goodwill
of The Tilden Group, and maintains The Tilden Group's Oakland, California

                                       16
<PAGE>   18

office staffed by ten former consultants of The Tilden Group. CRA has accounted
for this acquisition as a purchase transaction and will amortize the goodwill
acquired in the transaction over a period of 20 years.

     On February 25, 1999, CRA acquired assets and assumed specified liabilities
of Financial Economic Consulting, or FinEcon, for an aggregate of $3.2 million
in cash and common stock. CRA acquired accounts receivable, work in process,
fixed assets and the goodwill of FinEcon, and maintains FinEcon's Los Angeles,
California office staffed by ten former FinEcon consultants. CRA has accounted
for this acquisition as a purchase transaction and will amortize the goodwill
acquired in the transaction over a period of 20 years.

     From fiscal 1988 until April 1998, CRA was taxed as an S corporation and
did not pay federal and some state income taxes.

     CRA's fiscal year ends on the last Saturday in November and, accordingly,
CRA's fiscal year will periodically contain 53 weeks rather than 52 weeks. For
example, fiscal 1996 contained 53 weeks. This additional week of operations in
the fiscal year will affect the comparability of results of operations of these
53-week fiscal years with other fiscal years. Historically, CRA has managed its
business based on a four-week billing cycle to clients and, consequently, has
established quarters that are divisible by four-week periods. As a result, the
first, second and fourth quarters of each fiscal year are 12-week periods and
the third quarter of each fiscal year is a 16-week period. However, the fourth
quarter in 53-week fiscal years is 13 weeks long. Accordingly,
quarter-to-quarter comparisons of CRA's results of operations are not
necessarily meaningful if the quarters being compared have different lengths.

     The terms "fiscal 1994," "fiscal 1995," "fiscal 1997," "fiscal 1998" and
"fiscal 1999" refer to the 52-week periods ended November 26, 1994, November 25,
1995, November 29, 1997, November 28, 1998 and November 27, 1999, respectively,
and the term "fiscal 1996" refers to the 53-week period ended November 30, 1996.

TWENTY-FOUR WEEKS ENDED MAY 14, 1999 COMPARED TO TWENTY-FOUR WEEKS ENDED MAY 15,
1998

     Revenues.  Revenues increased by $8.5 million, or 37.3%, from $22.7 million
for the twenty-four weeks ended May 15, 1998 to $31.2 million for the
twenty-four weeks ended May 14, 1999. The increase in revenues was due primarily
to an increase in the number of employee consultants, an increase in consulting
services performed for new and existing clients during the period and, to a
lesser extent, increased billing rates of CRA's consultants. The acquisition of
personnel from The Tilden Group and, to a lesser extent, FinEcon, also
contributed to CRA's increase in revenue during the second quarter of fiscal
1999. CRA experienced revenue increases during the twenty-four weeks ended May
14, 1999 in its legal and regulatory consulting services, specifically in its
newly formed practice in international trade, as well as in its finance and
environment practice areas.

     Costs of Services.  Costs of services increased by $4.7 million, or 34.9%,
from $13.4 million in the twenty-four weeks ended May 15, 1998 to $18.1 million
in the twenty-four weeks ended May 14, 1999. As a percentage of revenues, costs
of services decreased slightly from 59.1% in the twenty-four weeks ended May 15,
1998 to 58.0% in the twenty-four weeks ended May 14, 1999. The decrease as a
percentage of revenues was due primarily to a relative decrease in bonuses paid
to employee consultants who source business to CRA. Also, CRA's consulting staff
did not increase at as fast a rate as the rate of increase of revenues in the
twenty-four weeks ended May 14, 1999.

     General and Administrative.  General and administrative expenses increased
by $1.9 million, or 34.6%, from $5.3 million in the twenty-four weeks ended May
15, 1998 to $7.2 million in the twenty-four weeks ended May 14, 1999. As a
percentage of revenues, general and administrative expenses decreased from 23.5%
in the twenty-four weeks ended May 15, 1998 to 23.1% in the twenty-four weeks
ended May 14, 1999. The dollar increase in general and administrative expenses
resulted from bonus payments to outside experts, increased rents due to internal
growth and amortization costs related to acquired businesses. The number of
outside experts has increased as a result of acquisitions.

     Interest Income, Net.  Net interest income increased from $226,000 in the
twenty-four weeks ended May 15, 1998 to $463,000 in the twenty-four weeks ended
May 14, 1999. This increase resulted primarily from interest earned on the
proceeds of CRA's initial public offering. This increase was offset slightly by
interest payments made as part of the acquisition of The Tilden Group.

     Provision for Income Taxes.  Provision for income taxes increased from $1.8
million in the twenty-four weeks ended May 15, 1998 to $2.6 million in the
twenty-four weeks ended May 14, 1999. The provision for the twenty-four weeks
ended May 15, 1998 consists of $364,000, reflecting taxation as an S corporation
for 150 days and taxation as a C corporation for 18 days, and $1.4 million for
the change in tax status to a C corporation, while the provision for the first
two quarters of fiscal 1999 reflects taxation as a C corporation for the entire
period.

     Minority Interest.  In June 1997, CRA established and purchased a
controlling interest in NeuCo, which provides applications consulting services
and a family of neural network software solutions and complementary applications
for fossil-fired electric utilities. Minority interest in the loss of NeuCo
decreased from $133,000 in the twenty-four weeks ended May 15, 1998 to $33,000
in the twenty-four weeks ended May 14, 1999 due to CRA's inability to allocate
continued losses of NeuCo to the minority interest holders as their minority
interest accounts have been reduced to zero.

FISCAL 1998 COMPARED TO FISCAL 1997

     Revenues.  Revenues increased by $8.2 million, or 18.2%, from $44.8 million
for fiscal 1997 to $53.0 million for fiscal 1998. The increase in revenues was
due primarily to an increase in consulting services performed for new and
existing clients during the period and an increase in the number of employee
consultants and increased billing rates of CRA's consultants. The number of
consultants increased from 121 in fiscal 1997 to 145 in fiscal 1998. CRA
experienced revenue increases during fiscal 1998 in both its legal and
regulatory consulting services and business consulting services, and in
particular generated significant revenue increases in its antitrust and mergers
and acquisitions practices.

                                       18
<PAGE>   20

     Costs of Services.  Costs of services increased by $3.3 million, or 11.7%,
from $28.4 million in fiscal 1997 to $31.7 million in fiscal 1998. As a
percentage of revenues, costs of services decreased from 63.3% in fiscal 1997 to
59.8% in fiscal 1998. The decrease as a percentage of revenues was due primarily
to the fact that CRA's consulting staff costs did not increase as quickly as the
rate of increase of revenues. In fiscal 1998 as compared to fiscal 1997,
utilization rates for CRA's employee consultants was higher, which positively
impacted revenues but had no impact on cost of services. In addition, CRA hired
more junior consultants, who typically generate higher margins than senior
consultants.

     Supplemental Compensation.  Beginning in fiscal 1998, CRA no longer paid
supplemental compensation, and consequently, did not have supplemental
compensation in fiscal 1998. Supplemental compensation was $1.2 million in
fiscal 1997.

     General and Administrative.  General and administrative expenses increased
by $1.4 million, or 13.6%, from $10.5 million in fiscal 1997 to $11.9 million in
fiscal 1998. As a percentage of revenues, general and administrative expenses
decreased from 23.5% in fiscal 1997 to 22.6% in fiscal 1998. General and
administrative expenses decreased as a percentage of revenues primarily because
CRA increased its administrative and labor costs at a slower rate than the rate
of increase of its employee consultants. In addition, the dollar increase in
general and administrative expenses was offset in part by CRA better utilizing
existing space and systems.

     Interest Income, Net.  Net interest income increased from $302,000 in
fiscal 1997 to $975,000 in fiscal 1998. This increase was due primarily to
interest earned on the proceeds of CRA's initial public offering.

     Minority Interest.  In June 1997, CRA established and purchased a
controlling interest in NeuCo. Minority interest increased from $282,000 in
fiscal 1997 to $310,000 in fiscal 1998, and represents the portion of NeuCo's
net loss after taxes allocable to its minority owners.

     Provision for Income Taxes.  The provision for income taxes increased from
$306,000 in fiscal 1997 to $4.3 million in fiscal 1998. The provision for fiscal
1998 consists of $2.9 million for current year operations, reflecting taxation
as an S corporation for 150 days and taxation as a C corporation for 214 days,
and $1.4 million for deferred tax resulting from the change in tax status to a C
corporation.

FISCAL 1997 COMPARED TO FISCAL 1996

     Revenues.  Revenues increased by $7.4 million, or 19.9%, from $37.4 million
for fiscal 1996 to $44.8 million for fiscal 1997. The increase in revenues was
due primarily to increased consulting services performed for new and existing
clients during that period. In fiscal 1997, CRA experienced revenue increases in
both its legal and regulatory consulting services and its business consulting
services, and in particular generated significant revenue increases in its
mergers and acquisitions, finance and auctions practices. During fiscal 1997,
CRA increased the number of its employee consultants from 112 to 121. The
increase in revenues during fiscal 1997 was also due in part to increased
billing rates of CRA's consultants.

     Costs of Services.  Costs of services increased by $5.0 million, or 21.4%,
from $23.4 million in fiscal 1996 to $28.4 million in fiscal 1997. As a
percentage of revenues, costs of services increased from 62.6% in fiscal 1996 to
63.3% in fiscal 1997. The increase as a percentage of revenues was due primarily
to slightly lower utilization rates for CRA's employee consultants during fiscal
1997, which resulted in part from consultants of CRA spending time developing
new practice areas that are complementary to CRA's core practice areas.

     Supplemental Compensation.  Supplemental compensation was $1.2 million for
each of fiscal 1996 and fiscal 1997. As a percentage of revenues, supplemental
compensation decreased from 3.2% in fiscal 1996 to 2.8% in fiscal 1997. CRA had
paid supplemental compensation of $1.2 million in each of its previous three
fiscal years and discontinued these payments after fiscal 1997.

     General and Administrative.  General and administrative expenses increased
by $1.4 million, or 16.0%, from $9.1 million in fiscal 1996 to $10.5 million in
fiscal 1997. As a percentage of revenues, general and administrative expenses
decreased from 24.2% in fiscal 1996 to 23.5% in fiscal 1997. General and

                                       19
<PAGE>   21

administrative expenses decreased as a percentage of revenues primarily because
CRA increased its administrative and support staff at a slower rate than the
rate of increase of its employee consultants.

     Interest Income, Net.  Net interest income increased from $124,000 for
fiscal 1996 to $302,000 for fiscal 1997. This increase was due primarily to CRA
generating more cash from operations during fiscal 1997, which resulted in CRA
maintaining higher cash balances during the year.

     Minority Interest.  Minority interest was $282,000 for fiscal 1997, and
represents the portion of NeuCo's net loss after taxes allocable to its minority
owners.

UNAUDITED QUARTERLY RESULTS

     The following table presents unaudited quarterly statements of income
information for the ten quarters ended May 14, 1999. The information for the
first two quarters of fiscal 1999 includes the results of operations
attributable to the acquisition of assets and liabilities of The Tilden Group
for the period after December 15, 1998. The information for the second quarter
of fiscal 1999 includes the results of operations attributable to the
acquisition of assets and liabilities of FinEcon for the period after February
25, 1999. The quarterly information for fiscal 1997 and fiscal 1998 is derived
from and is qualified by reference to the audited consolidated financial
statements included in this prospectus beginning on page F-1. In the opinion of
CRA's management, this information includes all adjustments, consisting only of
normal recurring adjustments, necessary for a fair presentation of the
information. The first, second and fourth quarters of each fiscal year are
12-week periods and the third quarter of each fiscal year is a 16-week period.
Accordingly, quarter-to-quarter comparisons of CRA's results of operations are
not necessarily meaningful if the quarters being compared have different
lengths. The results of operations for any quarter are not necessarily
indicative of the results to be expected for any future period. For risks
associated with fluctuations in our quarterly revenues and results of
operations, see "Risk Factors -- Fluctuations in our quarterly revenues and
results of operations could depress the market price of our common stock."

LIQUIDITY AND CAPITAL RESOURCES

     CRA's operating activities provided cash of $2.2 million in fiscal 1996,
$3.6 million in fiscal 1997 and $13.7 million in fiscal 1998. In fiscal 1996 and
fiscal 1997, cash from operating activities was generated primarily from net
income earned for the period, which increased from $3.6 million in fiscal 1996
to $5.0 million in fiscal 1997. Cash generated from operating activities was
partially offset by increases in unbilled services and accounts receivable,
reflecting increased services performed by CRA in fiscal 1996 and fiscal 1997.
In fiscal 1998, cash from operating activities resulted primarily from net
income of $6.4 million and an increase in accounts payable and accrued expenses
of $9.4 million, which reflects normal bonus accruals for fiscal 1998. In the
twenty-four weeks ended May 14, 1999, net cash used in operating activities was
$2.4 million, consisting primarily of a decrease in accounts payable and accrued
expenses, which reflects bonus payments made to employees as well as increases
in unbilled services and accounts receivable.

     Cash used in investing activities was $476,000 in fiscal 1996, $2.3 million
in fiscal 1997, $1.6 million in fiscal 1998 and $15.1 million in the twenty-four
weeks ended May 14, 1999. The increased use of cash for investing activities in
fiscal 1997 as compared to fiscal 1996 resulted primarily from CRA's expansion
of its three offices during fiscal 1997. Cash used in investing activities for
the twenty-four weeks ended May 14, 1999 consisted of $9.3 million for the
acquisitions of The Tilden Group and FinEcon, $4.9 million for purchase of
short-term investments and $860,000 for purchases of property and equipment.

     CRA's financing activities used cash of $1.3 million in fiscal 1996 and
$708,000 in fiscal 1997. A principal use of cash for financing activities in
those years was payment of dividends, which totaled $1.5 million in fiscal 1996
and $1.6 million in fiscal 1997. In fiscal 1997, CRA's use of cash for financing
activities was partially offset by collection of notes receivable from
stockholders, the sale of common stock to management of CRA and the investment
in NeuCo by minority interest owners. In fiscal 1998, CRA's

                                       21
<PAGE>   23

financing activities provided cash of $17.9 million. This consisted primarily of
the net proceeds of $29.5 million from the sale of stock in CRA's initial public
offering and the collection of notes receivable from shareholders of $381,000,
offset by the previously accrued 1997 tax distribution of $1.7 million, a $2.4
million supplemental dividend paid from the proceeds of the initial public
offering, and a final $8.0 million S corporation distribution paid to CRA's
stockholders. In the twenty-four weeks ended May 14, 1999, CRA's financing
activities used cash of $115,000 due primarily to payments made on notes payable
to former stockholders.

     As of May 14, 1999, CRA had cash and cash equivalents of $14.4 million and
working capital of $27.5 million.

     CRA presently has available a $2.0 million revolving line of credit with
BankBoston Corporation, which is secured by CRA's accounts receivable. This line
of credit automatically renews each year on June 30 unless earlier terminated by
either CRA or BankBoston. No borrowings were outstanding under this line of
credit as of May 14, 1999.

     In connection with the acquisition of assets and liabilities of The Tilden
Group on December 15, 1998, CRA paid $7.4 million, the cash portion of the
purchase price, from its working capital. In connection with the acquisition of
assets and liabilities of FinEcon on February 25, 1999, CRA paid $1.7 million,
the cash portion of the purchase price, from its working capital.

     CRA believes that its proceeds from the offering, its existing cash
balances and credit available under its bank line of credit will be sufficient
to meet its working capital and capital expenditure requirements for the next 12
months and for the foreseeable future thereafter.

     To date, inflation has not had a material impact on CRA's financial
results. Inflation may adversely affect CRA's future financial results.

QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

     As of May 14, 1999, CRA was exposed to market risks which primarily include
changes in U.S. interest rates.

     CRA maintains a portion of its cash and cash equivalents in financial
instruments with purchased maturities of one year or less and a portion of its
short-term investments in financial instruments with purchased maturities of two
years or less. These financial instruments are subject to interest rate risk and
will decline in value if interest rates increase. Due to the relatively short
duration of these financial instruments, an immediate increase in interest rates
would not have a material effect upon CRA's financial position.

YEAR 2000 COMPLIANCE

     The following information constitutes a "Year 2000 Readiness Disclosure"
under the Year 2000 Information and Readiness Disclosure Act.

     Many existing computer systems and software products do not properly
recognize dates after December 31, 1999. This "Year 2000" problem could result
in system failures or miscalculations causing disruptions of operations
including, among other things, a temporary inability to process transactions,
send invoices or engage in similar normal business activities. The inability of
products, services and systems on which CRA relies to process dates after
December 31, 1999 could seriously harm CRA's business.

     CRA has conducted tests and sought confirmation from software vendors to
determine whether the software it uses is Year 2000 compliant. Based on the
results of its investigation, CRA believes that all of its internal software
systems are Year 2000 compliant, except for its time-keeping and billing
software. CRA is planning to replace its time-keeping and billing software with
software that is Year 2000 compliant in the second half of calendar 1999. CRA
has purchased replacement time-keeping and billing software that has been
represented to be Year 2000 compliant. CRA is currently modifying this software
to simplify data entry and to customize reports to conform to CRA's current
billing practices. CRA expects to have completed, tested and implemented these
modifications by the end of October 1999. CRA believes that, with respect to
                                       22
<PAGE>   24

its internal systems, its reasonably likely worst case scenario is that it will
not have completed, tested and implemented these modifications on time. In that
event, CRA's contingency plan is to use the time-keeping and billing software
without the modifications, which will cause CRA to rely on manual methods for
some aspects of data entry and bill preparation. CRA believes these manual
methods could cause it to incur significant additional labor expenses, but will
not cause significant delays in the preparation and mailing of bills to clients.

     CRA estimates that the aggregate incremental costs that it has incurred and
will incur in order to comply with Year 2000 requirements will not exceed
$200,000. However, CRA may experience delays in implementing the replacement
software, which could disrupt its operations, create delays in billing clients
and require CRA to spend significant amounts of money to correct the problem.
Moreover, CRA may discover undetected Year 2000 errors or defects in its other
internal software systems and, if such errors or defects are discovered, the
costs of making such systems Year 2000 compliant could have a material adverse
effect on CRA's business, financial condition and results of operations.

     CRA relies on third-party vendors that may not be Year 2000 compliant for
some equipment and services. To date, CRA has not conducted a Year 2000 review
of all of its vendors. In many cases, these vendors have no obligation to
provide CRA with information regarding their Year 2000 compliance. Failure of
systems maintained by CRA's vendors to operate properly with regard to the Year
2000 and thereafter could require CRA to incur significant unanticipated
expenses to remedy any problems or replace affected vendors and could have a
material adverse effect on CRA's business, financial condition and results of
operations. Except as described above, CRA has not developed a contingency plan
to address situations that may arise if we or our vendors are unable to achieve
Year 2000 compliance. The cost of developing a contingency plan, if necessary,
could be significant.

INTRODUCTION

     CRA is a leading economic and business consulting firm that applies
advanced analytic techniques and in-depth industry knowledge to complex
engagements for a broad range of clients. Founded in 1965, CRA provides original
and authoritative advice for clients involved in many high-stakes matters, such
as multi-billion dollar acquisitions, new product introductions, major capital
investment decisions and complex litigation.

     CRA offers two types of services: legal and regulatory consulting and
business consulting. Through its legal and regulatory consulting practice, CRA
provides law firms and businesses involved in litigation and regulatory
proceedings with expert advice on highly technical issues. Through its business
consulting practice, CRA provides services directly to companies seeking
assistance with strategic issues that require expertise in economics, finance
and business analysis. For example, CRA provides advice on the following issues:

</TABLE>

     CRA combines expertise in advanced economic and financial methods with
in-depth knowledge of particular industries, such as chemicals, electric power
and other energies, healthcare, materials, media and telecommunications, retail
and wholesale distribution, and transportation.

     CRA's services are provided by its highly credentialed and experienced
staff of employee consultants. As of July 31, 1999, CRA employed 185 full-time
professional consultants, including 60 consultants with Ph.D.s and 39
consultants with other advanced degrees. CRA's consultants have backgrounds in a
wide range of disciplines, including economics, business, corporate finance,
materials sciences and engineering. CRA is extremely selective in its hiring of
consultants, recruiting individuals from leading universities, industry and
government. Many of CRA's consultants are nationally recognized as experts in
their respective fields, having published scholarly articles, lectured
extensively and been quoted in the press. To enhance the expertise it provides
to its clients, CRA maintains close working relationships with over 40 renowned
academic and industry experts, whom CRA refers to as outside experts. CRA has
exclusive relationships with 13 of these outside experts.

     CRA has completed more than 3,200 engagements for clients, including major
law firms, domestic and foreign corporations, federal, state and local
government agencies, governments of foreign countries, public and private
utilities, and national and international trade associations. While CRA has
particular expertise in a number of industries, CRA provides services to a
diverse group of clients in a broad range of industries. During its last three
fiscal years, CRA had over 1,400 engagements for clients that included 63 of the
100 largest U.S. law firms, ranked by The American Lawyer based on 1998
revenues, and 89 Fortune 500 companies, based on 1998 revenues. During that
period, CRA's clients included Cravath, Swaine & Moore; Ford Motor Company;
Jones, Day, Reavis & Pogue; Procter & Gamble Company Inc.; Skadden, Arps, Slate,
Meagher & Flom LLP; and Time Warner Inc. No single client accounted for over 10%
of CRA's revenues in fiscal 1998.

     Since CRA's initial public offering in April 1998, CRA has acquired The
Tilden Group and FinEcon. Both companies add well-known economists whose
specialties strengthen and expand CRA's consulting capabilities as well as its
geographic scope. In addition, CRA opened offices in Toronto, Ontario and Los
Angeles, California and has staffed both offices with leading economists and
outside experts.

                                       24
<PAGE>   26

     CRA's revenues and income from operations have increased from $37.4 million
and $3.7 million in fiscal 1996 to $53.0 million and $9.3 million in fiscal
1998, respectively, representing compound annual growth rates of 19.1% and
58.1%. CRA's revenues and income from operations have increased from $22.7
million and $4.0 million in the first twenty-four weeks of fiscal 1998 to $31.2
million and $5.9 million in the first twenty-four weeks of fiscal 1999,
representing period-to-period increases of 37.3% and 48.9%.

INDUSTRY OVERVIEW

     Businesses are operating in an increasingly complex environment. Expanding
access to powerful computers and software is providing companies with almost
instantaneous access to a wide range of internal information, such as supply
costs, inventory values, and sales and pricing data, as well as external
information, such as market demand forecasts and customer buying patterns. The
Internet is changing traditional distribution channels, thereby eliminating
barriers to entry in many industries, and spurring new competition. At the same
time, markets are becoming increasingly global, offering companies the
opportunity to expand their presence throughout the world and exposing them to
increased competition and the uncertainties of foreign operations. Many
industries are rapidly consolidating as companies pursue mergers and
acquisitions in response to increased competitive pressures and to expand their
market opportunities. In addition, companies are relying to a greater extent on
technological and business innovations to improve efficiency, thus increasing
the importance of strategically analyzing their businesses and developing and
protecting new technology. As a result of this increasingly competitive and
complex business environment, companies must constantly gather, analyze and use
available information to enhance their business strategies and operational
efficiencies.

     The increasing complexity and changing nature of the business environment
is also forcing governments to modify their regulatory strategies. For example,
industries such as healthcare are subject to frequently changing regulations
while other industries such as telecommunications and electric power are
experiencing trends toward deregulation. These constant changes in the
regulatory environment are leading to frequent litigation and interaction with
government agencies as companies attempt to interpret and react to the
implications of this changing environment. Furthermore, as the general business
and regulatory environment becomes more complex, corporate litigation has also
become more complicated, protracted, expensive and important to the parties
involved.

     As a result, companies are increasingly relying on sophisticated economic
and financial analysis to solve complex problems and improve decision-making.
Economic and financial models provide the tools necessary to analyze a variety
of issues confronting businesses, such as interpretation of sales data, effects
of price changes, valuation of assets, assessment of competitors' activities,
evaluation of new products and analysis of supply limitations. Governments are
also relying to an increasing extent on economic and finance theory to measure
the effects of anti-competitive activity, evaluate mergers and acquisitions,
change regulations, implement auctions to allocate resources and establish
transfer pricing rules. Finally, litigants and law firms are using economic and
finance theory to help determine liability and to calculate damages in complex
and high-stakes litigation. As the need for complex economic and financial
analysis becomes more widespread, CRA believes that companies and governments
are increasingly turning to outside consultants for access to the specialized
expertise, experience and prestige that are not available to them internally.

COMPETITIVE STRENGTHS

     Since 1965, CRA has been committed to providing sophisticated consulting
services to its clients. CRA believes that the following factors have been
critical to its success:

     Strong Reputation for High Quality Consulting.  For over 30 years, CRA has
been a leader in providing sophisticated economic analysis and original,
authoritative studies for clients involved in complex litigation and regulatory
proceedings. As a result, CRA believes that it has established a strong
reputation among leading law firm and business clients as a preferred source of
expertise in economics, finance, business and strategy consulting, as evidenced
by CRA's high level of repeat business and significant referrals from existing
clients. In fiscal 1998, approximately 90% of CRA's revenues resulted from
ongoing engagements

                                       25
<PAGE>   27

and new engagements for existing clients. In addition, CRA believes that its
significant name recognition, developed as a result of its work on many high
profile litigation and regulatory engagements, has enhanced the development of
its business consulting practice.

     Highly Educated, Experienced and Versatile Consulting Staff.  CRA believes
that its most important asset is its base of full-time employee consultants,
particularly its senior consultants. Of CRA's 185 consultants as of July 31,
1999, 99 are either officers, principals or senior associates, substantially all
of whom have a Ph.D. or a master's degree. Many of these senior consultants are
nationally recognized as experts in their respective fields, having published
scholarly articles, lectured extensively and been quoted in the press. In
addition to their expertise in a particular field, most of CRA's consultants are
able to apply their skills across numerous practice areas. This flexibility in
staffing engagements is critical to CRA's ability to apply its resources as
needed to meet the demands of its clients. As a result, CRA seeks to hire
consultants who not only have strong analytical skills, but who are also
creative, intellectually curious and driven to develop expertise in new practice
areas and industries.

     Strong Corporate Culture.  CRA believes its success has resulted in part
from its strong corporate culture. CRA believes that consultants are attracted
to CRA because of its more than 30-year history, its strong reputation, the
credentials, experience and reputation of its employee consultants, the
opportunity to work on a diverse array of matters, the opportunity to work with
a broad group of renowned outside experts, and CRA's collegial atmosphere. CRA
believes that its attractiveness as an employer is reflected in its relatively
low turnover rate among employees. CRA also believes that these factors make CRA
attractive to potential acquisition targets.

     Industry Expertise.  By maintaining expertise in certain industries, CRA is
able to offer clients creative and pragmatic advice tailored to their specific
markets. This industry expertise, developed by CRA over decades of providing
sophisticated consulting services to a diverse group of clients in industries
such as chemicals, electric power and other energies, healthcare, materials,
media and telecommunications, retail and wholesale distribution, and
transportation, differentiates CRA from many of its competitors. CRA believes
that it has developed a strong reputation and substantial name recognition
within these specific industries, which leads to repeat business and new
engagements from clients in those markets.

     Broad Range of Services.  By offering clients both legal and regulatory
consulting services and business consulting services, CRA is able to satisfy a
broad array of client needs, ranging from expert testimony for complex lawsuits
to designing global business strategies. This broad range of expertise enables
CRA to take an interdisciplinary approach to certain engagements, combining
economists and experts in one area with specialists in other disciplines. CRA
emphasizes its diverse capabilities to clients and regularly cross-markets
across its service areas. For example, it is not unusual for a client that CRA
assists in a litigation matter to later retain CRA for a business consulting
matter.

     Access to Leading Academic and Industry Experts.  To enhance the expertise
it provides to its clients, CRA maintains close working relationships with a
select group of outside experts. Depending on client needs, CRA uses outside
experts for their specialized expertise, assistance in conceptual
problem-solving and expert witness testimony. CRA works regularly with renowned
professors at Georgetown University, Harvard University, the Massachusetts
Institute of Technology, Northwestern University, Stanford University, the
University of California at Berkeley, the University of California at Los
Angeles, the University of Toronto, the University of Virginia and other leading
universities. Outside experts also generate business for CRA and provide CRA
access to other leading academic and industry experts. By establishing
affiliations with prestigious outside experts, CRA further enhances its
reputation as a leading source of sophisticated economic and financial analysis.
Since its initial public offering, CRA has increased the number of its exclusive
relationships with outside experts from four to thirteen.

GROWTH STRATEGY

     CRA intends to enhance its position as a leading economic and business
consulting firm by pursuing the following growth strategy:

     Attract and Retain High Quality Consultants as Employees.  Since CRA's
employee consultants are its most important asset, CRA's ability to attract and
retain highly credentialed and experienced consultants both to work on
engagements and to generate new business is crucial to its success. In order to
attract highly qualified consultants, CRA offers competitive compensation and
benefits and has developed a career enhancement program that offers consultants
career enrichment opportunities and access to individualized training. CRA
grants stock options to certain employees as part of its effort to attract and
retain consultants, and offers employees the opportunity to purchase stock in
CRA through an employee stock purchase plan.

     Increase Marketing Activities.  Although CRA has historically relied
primarily on its reputation and client referrals for new business, it has begun
to expand its marketing activities in order to attract new clients and increase
the overall exposure of its employee consultants. For example, CRA has increased
its presence at selected conferences, seminars and public speaking engagements
to generate additional client referrals and leads for new clients. CRA has also
increased circulation of its publications to clients, which highlight emerging
trends and noteworthy CRA engagements, and has encouraged its consultants to
publish articles more frequently in the trade press and academic journals. CRA
intends to continue to pursue these and other opportunities to expand its
marketing activities.

     Expand Services.  While CRA currently offers a broad range of services, CRA
believes there are opportunities to expand the services and expertise it
provides to its clients. For example, CRA recently significantly expanded its
legal and regulatory consulting services in international trade, particularly
with respect to antidumping, countervailing duty investigations and other
international trade disputes. Similarly, CRA believes that it can expand into
other related areas of business with its existing employee consultants, most of
whom have experience in a wide variety of fields. To encourage the development
of new ideas and expertise, CRA fosters an environment that rewards creativity
and innovation.

     Establish Relationships with Additional Outside Experts.  CRA intends to
continue to establish relationships with additional leading academic and
industry experts. Since its initial public offering, CRA has established
exclusive relationships with nine additional outside experts. In addition to
helping CRA serve its clients better, outside experts often provide CRA with new
sources of business and expand CRA's network of academic affiliations. Moreover,
CRA believes that affiliations with additional, prestigious outside experts will
further enhance its reputation and aid in recruiting consultants. CRA may grant
stock options to attract additional outside experts.

     Pursue Strategic Acquisitions and Alliances.  CRA intends to continue to
expand its operations through the acquisition of complementary businesses and by
establishing strategic alliances. Given the highly fragmented nature of the
consulting industry, CRA believes that there are numerous opportunities to
acquire small consulting firms. For example, CRA acquired The Tilden Group in
December 1998 and FinEcon in February 1999. CRA believes the acquisition of
complementary businesses and the establishment of strategic alliances will
provide it with additional employee consultants, new service offerings,
additional industry expertise, a broader client base or offices in new
geographic locations.

     There can be no assurance that CRA will be successful in any of the
elements of its growth strategy.

SERVICES

     CRA offers services in two broad areas: legal and regulatory consulting and
business consulting. In its legal and regulatory consulting practice, CRA
usually works closely with law firms on behalf of one or more companies involved
in litigation or regulatory proceedings. Many of the lawsuits and regulatory
proceedings in which CRA is involved are high-stakes matters, such as obtaining
regulatory approval of a pending merger or analyzing possible damages awards in
a securities fraud case. The ability to formulate and effectively communicate
powerful economic and financial arguments to courts and regulatory agencies is
often critical to a successful outcome in litigation and regulatory proceedings.
Through its highly educated and experienced
                                       27
<PAGE>   29

consulting staff, CRA applies advanced analytic techniques in economics and
finance to complex engagements for a diverse group of clients.

     In its business consulting practice, CRA typically provides services
directly to companies seeking assistance with strategic issues that require
expert economic or financial analysis. Many of these matters involve
"mission-critical" decisions for the client, such as positioning and pricing a
new product or developing a new technological process. CRA applies a highly
analytical, quantitative approach to help companies analyze and respond to
market forces and competitive pressures that affect their businesses. CRA
advises its clients in many of the same areas in which it provides legal and
regulatory consulting, such as finance and mergers and acquisitions. Applying
its in-depth knowledge of specific industries, CRA is able to provide
insightful, value-added advice to its clients. CRA offers clients practical and
creative advice by challenging conventional approaches and generally avoiding
predetermined solutions or methodologies.

     Engagements in CRA's two service areas often involve similar areas of
expertise and address related issues, and it is common for CRA's employee
consultants to work on engagements in both service areas. CRA estimates that it
derived approximately 70% of its revenues in fiscal 1998 from legal and
regulatory consulting and approximately 30% from business consulting.

     CRA offers its clients a wide range of legal, regulatory and business
consulting services, including the following:

INDUSTRY EXPERTISE

     CRA believes its ability to combine expertise in advanced economic and
financial methods with in-depth knowledge of particular industries is one of its
key competitive strengths. By maintaining expertise in certain industries, CRA
provides clients practical advice that is tailored to their specific markets.
This industry

                                       29
<PAGE>   31

expertise, which CRA developed over decades of providing sophisticated
consulting services to a diverse group of clients in many industries,
differentiates CRA from many of its competitors. CRA believes that it has
developed a strong reputation and substantial name recognition within specific
industries, which leads to repeat business and new engagements from clients in
those markets. While CRA provides services to clients in a wide variety of
industries, it has particular expertise in the following industries:

     - Chemicals

     - Electric Power and Other Energies

     - Healthcare

     - Materials

     - Media and Telecommunications

     - Retail and Wholesale Distribution

     - Transportation

CLIENT ENGAGEMENTS

     The following are examples of CRA's engagements:

  Legal and Regulatory Consulting

     CRA assisted Sprint in evaluating the economic impact of the proposed
merger of WorldCom and MCI on the core backbone market, which is the group of
providers that are instrumental in ensuring the connectivity upon which other
Internet service providers, or ISPs, and ultimately all Internet users, depend.
The WorldCom-MCI merger could increase the amount of Internet traffic
attributable to the combined network and thereby increase the risk that the
merged entity would either discontinue or degrade the quality of interconnection
services available to competing core backbone providers, including Sprint. CRA
applied sophisticated analytical techniques to issues of network externalities,
market concentration and competition. For competitive reasons, the US Department
of Justice and the European Commission conditioned approval of the merger on
divestiture of either the WorldCom or MCI backbone. To satisfy this condition,
MCI sold InternetMCI, including MCI's retail business, to Cable & Wireless.

     CRA assisted attorneys representing the three subscription digital audio
services that offer direct satellite broadcasts -- Digital Cable Radio (or Music
Choice), Digital Music Express, and DiSH CD -- in proceedings before the
Copyright Arbitration Royalty Panel, or CARP, to determine licensing royalty
rates for the public performance of digital sound recordings under the Digital
Performance Right in Sound Recordings Act of 1995. CRA presented analysis and
testimony challenging the reasonableness of evidence of economic behavior
presented by the Recording Industry Association of America to support a high
royalty rate. CRA believes its analysis and testimony persuaded the CARP, and
ultimately the Register of Copyrights on review of the CARP proceeding, to
approve rates much lower than those proposed by the RIAA.

  Business Consulting

     CRA assisted an international mining company in developing a strategy to
enhance shareholder value in prevailing market conditions. CRA was retained to
work closely with top management to assess the company's production
capabilities, competitive positioning and marketing capabilities, and then to
recommend specific actions for cost savings and for growth investments. CRA
helped management choose key strategic options and develop a strategy, and then
presented the recommendations to the company's board. As a direct result of
CRA's industry expertise and market knowledge, the company has embarked on an
ambitious implementation schedule and already begun to realize some benefits.

     CRA assisted a global producer of commodity surfactants in positioning
itself along the chain from feedstock through specialty surfactants. The client
faced two decisions: whether it should invest in broadening its position into
potentially higher-value specialty products, and whether it was sufficiently
positioned in
                                       30
<PAGE>   32

feedstocks to be a long-term leader. Drawing on its deep knowledge of chemicals
processes and markets, CRA examined the scale required to be a viable player,
the scope of the product portfolio, the technology requirements and the value of
integration. CRA recommended a major effort to improve positioning in upstream
integration as the first stage of the strategy. As a second stage, the client
developed an investment program in specialty surfactants, focusing on key
functions and markets where it could generate value. Today, the client is well
positioned across a range of highly valued specialty product areas.

HUMAN RESOURCES

     On July 31, 1999, CRA had 185 full-time employee consultants, consisting of
37 officers, 62 other senior consultants (either principals or senior
associates) and 86 junior consultants (either associates or analysts), and had
over 74 full-time administrative staff members. Officers and principals
generally work closely with clients, supervise junior consultants, provide
expert testimony on occasion and seek to generate business for CRA. Senior
associates and associates typically serve as project managers and handle complex
research assignments. Analysts gather and analyze data sets and complete
statistical programming and library research.

     CRA derives most of its revenues directly from the services provided by its
full-time employee consultants. CRA's consultants have backgrounds in many
disciplines, including economics, business, corporate finance, materials
sciences and engineering. Substantially all of CRA's senior consultants,
consisting of officers, principals and senior associates, have either a Ph.D. or
a master's degree in addition to substantial management, technical or industry
expertise. Of CRA's total senior consulting staff of 99 as of July 31, 1999, 53
have Ph.D.s in economics, 7 have Ph.D.s in other disciplines and 28 have other
advanced degrees. CRA believes that its financial results, reputation and growth
are directly related to the number and quality of its consultants.

     CRA is highly selective in its hiring of employee consultants, recruiting
primarily from leading universities, industry and government. CRA believes that
consultants choose to work at CRA because of its strong reputation, the
credentials, experience and reputation of its consultants, the opportunity to
work on a diverse array of matters, the opportunity to work with renowned
outside experts, and CRA's collegial atmosphere. CRA believes that its
attractiveness as an employer is reflected in its relatively low turnover rate
among employees. In 1998, CRA restructured its recruiting operations to
decentralize hiring and implement a team hiring approach. CRA has designated two
or more recruiting teams at each of its principal offices and given each team
responsibility for identifying, interviewing and hiring qualified candidates.
Teams have specific hiring goals for fiscal 2000. CRA has also expanded the
group of leading universities and degree programs from which it selects
candidates.

     CRA's training and career development program for its employee consultants
focuses on three areas: supervision, seminars and scheduled courses. This
program is designed to complement on-the-job experience and an employee's
pursuit of his or her own career development. New consultants participate in a
structured program in which they are partnered with an assigned mentor. Through
CRA's ongoing seminar program, outside speakers make presentations and conduct
discussions with the consultants on various topics. In addition, consultants are
expected to present papers, discuss significant cases, or outline new analytical
techniques or marketing opportunities periodically at in-house seminars. CRA
also provides scheduled courses designed to improve an employee's professional
skills, such as presentation and sales and marketing techniques. CRA also
encourages its consultants to pursue their academic interests by writing
articles for economic and other journals.

     Each of CRA's senior employee consultants has signed a non-solicitation
agreement which generally prohibits the employee from soliciting CRA's clients
for a period of six months following termination of the person's employment with
CRA and from soliciting CRA's employees for a period of two years after
termination of the person's employment. In order to align each officer's
interest with the overall interests and profitability of CRA, CRA has adopted a
policy requiring each of its officers to have an equity interest in CRA. All of
CRA's senior consultants who were stockholders of CRA before its initial public
offering are parties to a stock restriction agreement that prohibits them from
selling or otherwise transferring shares of

                                       31
<PAGE>   33

common stock held immediately before the initial public offering except under
certain circumstances. For more information on this agreement, see "Principal
and Selling Stockholders -- Stock Restriction Agreement."

     In addition, CRA works closely with a select group of approximately 40
outside experts from leading universities and industry, who supplement the work
of CRA's employee consultants and generate business for CRA. In fiscal 1998, six
of CRA's outside experts generated engagements that accounted for approximately
19% of CRA's revenues. CRA believes that outside experts choose to work with CRA
on engagements because of the interesting and challenging nature of the work
involved, the opportunity to work with CRA's highly educated consultants and the
financially rewarding nature of the work. Thirteen outside experts have entered
into agreements with CRA that restrict their right to compete with CRA.

MARKETING

     CRA relies to a significant extent on the efforts of its employee
consultants, particularly its officers and principals, to market CRA's services.
CRA encourages its consultants to generate new business from both existing and
new clients, and rewards its consultants with increased compensation and
promotions for obtaining new business. In pursuing new business, CRA's
consultants emphasize CRA's institutional reputation and experience, while also
promoting the expertise of the particular employees who will work on the matter.
Many of CRA's consultants have published articles in industry, business,
economic, legal and scientific journals and have made speeches and presentations
at industry conferences and seminars, which serve as a means of attracting new
business and enhancing their reputations. On occasion, consultants work with one
or more outside experts to market CRA's services.

     CRA supplements the personal marketing efforts of its employee consultants
with firm-wide initiatives. Historically, CRA relied primarily on its reputation
and client referrals for new business. Since 1995, CRA has increased its
marketing activities. CRA regularly organizes seminars for existing and
potential clients featuring panel members that include CRA's consultants,
outside experts and leading government officials. CRA has an extensive set of
brochures organized around CRA's service areas, which outline CRA's experience
and capabilities. In 1998, CRA increased the frequency with which it distributes
publications to existing and potential clients highlighting emerging trends and
noteworthy CRA engagements. Because existing clients are an important source of
repeat business and referrals, CRA communicates regularly with its existing
clients to keep them informed of developments that affect their markets and
industries.

     In its legal and regulatory consulting practice, CRA derives much of its
new business from referrals by existing clients. CRA has worked with leading law
firms across the country and believes it has developed a reputation among law
firms as a preferred source of sophisticated economic advice for litigation and
regulatory work. For its business consulting practice, CRA also relies on
referrals from existing clients, but supplements referrals with a significant
amount of direct marketing to new clients through conferences, publications,
presentations and direct solicitations.

     It is important to CRA that it conduct business ethically and in accordance
with industry standards and CRA's own rigorous professional standards. CRA
carefully considers the pursuit of each specific market, client and engagement.
Before CRA accepts a new client or engagement, CRA determines whether a conflict
of interests exists by circulating a client development report among its
officers and by checking its internal client database.

COMPETITION

     The market for economic and business consulting services is intensely
competitive, highly fragmented and subject to rapid change. In general, there
are few barriers to entry into CRA's markets, and CRA expects to face additional
competition from new entrants into the economic and business consulting
industries. In the legal and regulatory consulting market, CRA competes
primarily with other economic consulting firms and individual academics. CRA
believes that the principal competitive factors in this market are reputation,
analytical ability, industry expertise and service. In the business consulting
market, CRA competes primarily with other business and management consulting
firms, specialized or industry-specific consulting firms, the
                                       32
<PAGE>   34

consulting practices of large accounting firms, and the internal professional
resources of existing and potential clients. CRA believes that the principal
competitive factors in this market are reputation, industry expertise,
analytical ability, service and price. Many of CRA's competitors have national
and international reputations as well as significantly greater personnel,
financial, managerial, technical and marketing resources than CRA. Some of CRA's
competitors also have a significantly broader geographic presence than CRA. CRA
may be unable to compete successfully with its existing competitors or with any
new competitors.

FACILITIES

     In the aggregate, CRA leases approximately 90,000 square feet of office
space in the following offices: CRA's headquarters in Boston, Massachusetts; two
offices in Los Angeles, California; and one office in each of Oakland,
California; Palo Alto, California; Toronto, Ontario; and Washington, D.C. All of
CRA's offices are electronically linked together and have access to CRA's core
consulting tools. CRA believes that its existing facilities are adequate to meet
its current requirements and that suitable space will be available as needed.

LEGAL PROCEEDINGS

     CRA is not a party to any legal proceedings the outcome of which, in the
opinion of its management, would have a material adverse effect on its business,
financial condition or results of operations.

a governance committee. The compensation committee provides recommendations to
the board of directors concerning salaries and incentive compensation for
employees of and consultants to CRA. The audit committee reviews the scope and
results of the audit and other services provided by CRA's independent auditors.
The governance committee nominates persons to serve as directors of CRA.

     There are no family relationships among the directors and executive
officers of CRA.

the sale by CRA and the selling stockholders of the shares of common stock
offered by this prospectus by:

     - each person known by CRA to be the beneficial owner of more than five
       percent of the common stock;

     - each of CRA's directors;

     - each of CRA's executive officers;

     - all directors and executive officers of CRA as a group; and

     - each selling stockholder.

     The persons named in this table have sole voting and investment power with

STOCK RESTRICTION AGREEMENT

     Each person who was a stockholder of CRA before CRA's initial public
offering is subject to a stock restriction agreement with CRA. The stock
restriction agreement prohibits each pre-IPO stockholder from selling or
otherwise transferring shares of common stock held immediately before the IPO as
follows:

     - before April 24, 2000, no pre-IPO stockholder may sell any of his or her
       pre-IPO stock, except that he or she may sell pre-IPO stock in public
       offerings;

     - from April 24, 2000 to April 23, 2003, each pre-IPO stockholder will be
       able to sell up to an aggregate of 50% of his or her pre-IPO stock, less
       any shares previously sold in public offerings;

                                       37
<PAGE>   39

     - from April 24, 2003 to April 23, 2005, each pre-IPO stockholder will be
       able to sell up to an aggregate of an additional 20% of his or her
       pre-IPO stock; and

     - on and after April 24, 2005, each pre-IPO stockholder will be able to
       sell, in any 12-month period, an amount equal to the greater of:

          - 10% of his or her pre-IPO stock, or

          - one-third of the pre-IPO stock held by him or her on April 24, 2005.

Upon the death or retirement for disability of any pre-IPO stockholder in
accordance with CRA's policies, the foregoing restrictions will terminate with
respect to his or her pre-IPO stock. The board of directors has the discretion
to waive any of the restrictions imposed by the stock restriction agreement and
has waived all restrictions that apply to shares to be sold in this offering.

     Under the terms of the stock restriction agreement, if any pre-IPO
stockholder leaves CRA other than for death or retirement for disability in
accordance with CRA's policies, CRA will have the right to repurchase his or her
pre-IPO stock as follows:

     - before April 24, 2000, CRA may repurchase up to 85% of his or her pre-IPO
       stock;

     - from April 24, 2000 to April 23, 2003, CRA may repurchase up to 50% of
       his or her pre-IPO stock; and

     - on and after April 24, 2003, CRA may repurchase all of the pre-IPO stock
       that the pre-IPO stockholder did not already become entitled to sell.

The purchase price will be equal to 70% of the fair market value of the
repurchased stock (95% in the case of pre-IPO stockholders who retire on or
after April 24, 2003), or, if the pre-IPO stockholder competes with CRA, 40% of
fair market value. The purchase price will be payable in three equal annual
installments. The stock restriction agreement will terminate on April 23, 2008
or earlier with the approval of the board of directors of CRA.

                          DESCRIPTION OF CAPITAL STOCK

     CRA's authorized capital stock consists of 25,000,000 shares of common
stock and 1,000,000 shares of preferred stock. As of July 31, 1999, there were
8,468,544 shares of common stock outstanding and no shares of preferred stock
outstanding.

COMMON STOCK

     Holders of common stock are entitled to one vote per share for each share
held of record on all matters submitted to a vote of stockholders. Subject to
preferences that may be applicable to the holders of outstanding preferred
stock, if any, the holders of common stock are entitled to receive whatever
lawful dividends the board of directors may declare. In the event of a
liquidation, dissolution or winding up of the affairs of CRA, whether voluntary
or involuntary, and subject to the rights of the holders of outstanding
preferred stock, if any, the holders of common stock will be entitled to receive
pro rata all of the remaining assets of CRA available for distribution to its
stockholders. The common stock has no preemptive, redemption, conversion or
subscription rights. All outstanding shares of common stock are fully paid and
non-assessable, except for installments not yet due and payable by a stockholder
of CRA. As of July 31, 1999, the stockholder owed CRA an aggregate of $9,898 in
future installments. The shares of common stock that CRA will issue in the
offering will be fully paid and non-assessable.

PREFERRED STOCK

     CRA's amended and restated articles of organization authorize the board of
directors, subject to any limitations prescribed by Massachusetts law, to issue
preferred stock in one or more series, to establish from time to time the number
of shares in each series and to fix the preferences, voting powers,
qualifications, and special or relative rights or privileges of the preferred
stock. The board of directors may issue preferred stock with voting, conversion,
and other rights and preferences that could adversely affect the voting power or
other rights of the holders of common stock. Although CRA has no current plans
to issue any preferred stock, the issuance of preferred stock or of rights to
purchase preferred stock could have the effect of making it more difficult for a
third party to acquire, or of discouraging a third party from attempting to
acquire, a majority of the outstanding voting stock of CRA.

ANTI-TAKEOVER EFFECTS OF PROVISIONS OF CRA'S ARTICLES OF ORGANIZATION AND
BY-LAWS AND OF MASSACHUSETTS LAW

     CRA's amended and restated articles of organization and amended and
restated by-laws and Massachusetts law contain provisions that could have
anti-takeover effects and that could discourage, delay or prevent a change in
control of CRA or an acquisition of CRA at a price that many stockholders may
find attractive. These provisions may also discourage proxy contests and make it
more difficult for stockholders of CRA to effect some corporate actions,
including the election of directors. The existence of these provisions could
limit the price that investors might be willing to pay in the future for shares
of common stock.

  Articles and By-Laws

     CRA's by-laws provide that, in order to nominate any person for election as
a director of CRA at any annual or special meeting of stockholders, a
stockholder must notify CRA of the nomination a specified number of days before
the meeting and must furnish to CRA information about the stockholder and the
intended nominee. Similarly, the by-laws provide that, in order to bring any
business before any annual or special meeting of stockholders, a stockholder
must provide advance notice of the proposal to CRA and must furnish to CRA
information about the stockholder, other supporters of the proposal, their stock
ownership and their interest in the proposed business.

     CRA's by-laws require CRA to call a special meeting of stockholders only at
the request of stockholders holding at least 40% of the voting power of CRA. The
provisions in the by-laws pertaining to stockholders and directors, including
the provisions described above pertaining to nominations and the presentation of
business before a meeting of the stockholders, may not be amended, nor may any
other provision inconsistent
                                       39
<PAGE>   41

with those provisions be adopted, without the approval of either the board of
directors or the holders of at least 80% of the voting power of CRA.

     CRA's articles provide that certain transactions, such as the sale, lease
or exchange of all or substantially all of CRA's property and assets or the
merger or consolidation of CRA into or with any other corporation, may be
authorized by the approval of the holders of a majority of the shares of each
class of stock entitled to vote on the matter, rather than by two-thirds as
otherwise provided by statute, but only if a majority of the directors has
authorized the transaction and all other applicable requirements of the articles
have been met.

     CRA's articles contain a "fair price" provision that provides that certain
"business combinations" with any "interested stockholder," as those terms are
defined in the fair price provision, may not be consummated without the approval
of the holders of at least 80% of the voting power of CRA, unless approved by at
least a majority of the "disinterested directors," as defined in the fair price
provision, or unless certain minimum price and procedural requirements are met.
A significant purpose of the fair price provision is to deter a purchaser from
using two-tiered pricing and similar unfair or discriminatory tactics in an
attempt to acquire control of CRA. The affirmative vote of the holders of 80% of
the voting power of CRA is required to amend or repeal the fair price provision
or adopt any provision inconsistent with it.

  Massachusetts Law

     CRA is subject to Chapter 110F of the Massachusetts General Laws, an
anti-takeover law. In general, this statute prohibits a publicly held
Massachusetts corporation from engaging in a "business combination" with an
"interested stockholder" for three years after the date of the transaction in
which the person becomes an interested stockholder, unless either:

     - before that date, the board of directors approved either the business
       combination or the transaction in which the person became an interested
       stockholder;

     - the interested stockholder acquires 90% of the outstanding voting stock
       of the corporation (excluding shares held by affiliates of the
       corporation) at the time it becomes an interested stockholder; or

     - the business combination is approved by the board of directors and by the
       holders of two-thirds of the outstanding voting stock of the corporation
       (excluding shares held by the interested stockholder) voting at a
       meeting.

In general, an "interested stockholder" under the statute is a person who owns
5% or more of the outstanding voting stock of the corporation, or 15% or more in
the case of a person eligible to file a Schedule 13G under the Securities
Exchange Act with respect to that voting stock, or a person who is an affiliate
or associate of the corporation and within the previous three years was the
owner of 5% or more of the outstanding voting stock of the corporation, or 15%
or more in the case of a person eligible to file a Schedule 13G with respect to
that voting stock. A "business combination" under the statute includes mergers,
consolidations, stock and asset sales, and other transactions with the
interested stockholder resulting in a financial benefit to the interested
stockholder, except proportionately as a stockholder of the corporation. CRA may
at any time amend its articles or by-laws to elect not to be governed by Chapter
110F by a vote of the holders of a majority of its voting stock. Such an
amendment would not be effective for twelve months and would not apply to a
business combination with any person who became an interested stockholder before
the date of the amendment.

     CRA is subject to Section 50A of Chapter 156B of the Massachusetts General
Laws, which requires that any publicly held Massachusetts corporation have a
classified, or staggered, board of directors unless the corporation opts out of
the statute's coverage. CRA has not elected to opt out of the statute's
coverage. Section 50A requires that the classified board consist of three
classes as nearly equal in size as possible and provides that directors may be
removed only for cause, as defined in the statute.

     CRA's by-laws exempt CRA from Chapter 110D of the Massachusetts General
Laws, entitled "Regulation of Control Share Acquisitions." In general, this
statute provides that any stockholder who acquires 20% or more of the
outstanding voting stock of a corporation subject to this statute may not vote

                                       40
<PAGE>   42

that stock unless the disinterested stockholders of the corporation so
authorize. In addition, Chapter 110D permits a corporation to provide in its
articles of organization or by-laws that the corporation may redeem, for fair
value, all of the shares acquired in a control share acquisition if the
interested stockholder does not deliver a control share acquisition statement or
if the interested stockholder delivers a control share acquisition statement but
the stockholders of the corporation do not authorize voting rights for those
shares. The board of directors may amend the by-laws at any time to subject CRA
to this statute prospectively.

     Under Section 43 of Chapter 156B of the Massachusetts General Laws, any
action taken by written consent of the stockholders requires the unanimous
written consent of the stockholders entitled to vote on the matter.

LIMITATION OF LIABILITY

     CRA's articles provide that no director of CRA will be personally liable to
CRA or to its stockholders for monetary damages for breach of fiduciary duty as
a director, except that the limitation will not eliminate or limit liability:

     - for any breach of the director's duty of loyalty to CRA or its
       stockholders;

     - for acts or omissions not in good faith or which involve intentional
       misconduct or a knowing violation of law;

     - under Section 61 or 62 of Chapter 156B of the Massachusetts General Laws,
       dealing with liability for unauthorized distributions and loans to
       insiders, respectively; or

     - for any transaction from which the director derived an improper personal
       benefit.

     CRA's articles and by-laws further provide for the indemnification of CRA's
directors and officers to the fullest extent permitted by Section 67 of Chapter
156B of the Massachusetts General Laws, including circumstances in which
indemnification is otherwise discretionary.

     A principal effect of these provisions is to limit or eliminate the
potential liability of CRA's directors for monetary damages arising from
breaches of their duty of care, unless the breach involves one of the four
exceptions described above. These provisions may also shield directors from
liability under federal and state securities laws.

     - the right to reject orders in whole or in part.

     The underwriters have an option to buy up to 255,000 additional shares of
common stock from the selling stockholders. These additional shares would cover
sales of shares by the underwriters which exceed the number of shares specified
in the table above, and will be sold by the selling stockholders on a pro rata
basis if the underwriters do not exercise this option in full. The underwriters
have 30 days to exercise this option. If the underwriters exercise this option,
they will each purchase additional shares approximately in proportion to the
amounts specified in the table above. CRA will pay the expenses, other than the
underwriting discounts and commissions paid by the selling stockholders,
associated with the exercise of the over-allotment option.

     The following table shows the per share and total underwriting discounts
and commissions to be paid to the underwriters by CRA and the selling
stockholders. Such amounts are shown assuming no exercise and full exercise of
the underwriters' option to purchase additional shares.

     CRA and its directors, executive officers and certain other stockholders of
CRA, who will hold in the aggregate approximately           shares of common
stock after the offering, have entered into lock-up agreements with the
underwriters. Under those agreements, CRA and those directors, executive
officers and stockholders may not dispose of or hedge any CRA common stock or
securities convertible into or exchangeable for shares of CRA common stock
unless permitted to do so by Banc of America Securities LLC. These restrictions
will be in effect for a period of 90 days after the date of this prospectus. At
any time and without notice, Banc of America Securities LLC may, in its sole
discretion, release all or some of the securities from these lock-up agreements.

     CRA and the selling stockholders will indemnify the underwriters against
liabilities under the Securities Act and other liabilities. If CRA and the
selling stockholders are unable to provide this indemnification, they will
contribute to payments the underwriters may be required to make in respect of
those liabilities.

     In connection with this offering, the underwriters may engage in activities
that stabilize, maintain or otherwise affect the price of the common stock,
including:

     - short sales

     - stabilizing transactions

     - purchases to cover positions created by short sales.

     Short sales involve the sale by the underwriters of a greater number of
shares than they are required to purchase in this offering. Stabilizing
transactions consist of bids or purchases made for the purpose of preventing or
retarding a decline in the market price of the common stock while this offering
is in progress.

     The underwriters also may impose a penalty bid. This means that if the
representatives purchase shares in the open market in stabilizing transactions
or to cover short sales, the representatives can require the underwriters that
sold those shares as part of this offering to repay the underwriting discount
received by them.

     As a result of these activities, the price of the common stock may be
higher than the price that otherwise might exist in the open market. If the
underwriters commence these activities, they may discontinue them at any time.
The underwriters may carry out these transactions on the Nasdaq National Market,
in the over-the-counter-market or otherwise.

                                 LEGAL MATTERS

     The validity of the shares of common stock offered by this prospectus will
be passed upon for CRA and the selling stockholders by Foley, Hoag & Eliot LLP,
Boston, Massachusetts. Certain legal matters will be passed upon for the
underwriters by Hale and Dorr LLP, Boston, Massachusetts.

                         REPORT OF INDEPENDENT AUDITORS

Board of Directors
Charles River Associates Incorporated

     We have audited the accompanying consolidated balance sheets of Charles
River Associates Incorporated (the "Company") as of November 29, 1997 and
November 28, 1998, and the related consolidated statements of income,
stockholders' equity, and cash flows for each of the three years in the period
ended November 28, 1998. 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 consolidated financial position of Charles River
Associates Incorporated as of November 29, 1997 and November 28, 1998, and the
consolidated results of its operations and its cash flows for each of the three
years in the period ended November 28, 1998, in conformity with generally
accepted accounting principles.

                     CHARLES RIVER ASSOCIATES INCORPORATED

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

DESCRIPTION OF BUSINESS

     Charles River Associates Incorporated ("CRA") is an economic and business
consulting firm that applies advanced analytic techniques and in-depth industry
knowledge to complex engagements for a broad range of clients. CRA offers two
types of services: legal and regulatory consulting and business consulting.

ESTIMATES

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

FISCAL YEAR

     CRA's fiscal year ends on the last Saturday in November. The fiscal year
ended November 30, 1996 consisted of 53 weeks; the fiscal years ended November
29, 1997 and November 28, 1998 each consisted of 52 weeks.

RECLASSIFICATION

     Certain amounts in 1997 have been reclassified to permit comparison with
1998.

REVENUE RECOGNITION

     Revenues from most engagements are recognized as services are provided
based upon hours worked and contractually agreed-upon hourly rates. CRA's
revenues also include expenses billed to clients, which include travel and other
out-of-pocket expenses, charges for support staff and outside contractors and
other reimbursable expenses. An allowance is provided for any amounts considered
uncollectible.

     Unbilled services represent balances accrued by CRA for services performed
but not yet billed to the client.

CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS

     Cash equivalents consist principally of money market funds, commercial
paper, bankers' acceptances and certificates of deposit with maturities when
purchased of 90 days or less. Short-term investments consist of commercial paper
and certificates of deposit with maturities when purchased of more than 90 days
but less than one year.

PROPERTY AND EQUIPMENT

     Property and equipment are recorded at cost. CRA provides for depreciation
of equipment using the straight-line method over its estimated useful life,
generally three to five years. Amortization of leasehold improvements is
provided using the straight-line method over the shorter of the lease term or
the estimated useful life of the leasehold improvements.

PRINCIPLES OF CONSOLIDATION

     The consolidated financial statements include the accounts of CRA, its
subsidiaries and NeuCo LLC, a limited liability company founded by CRA and an
affiliate of Commonwealth Energy Systems in June 1997.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

CRA has a 65.5% interest in NeuCo LLC. The portion of the results of operations
of NeuCo LLC allocable to its minority owners is shown as "minority interest" in
CRA's statement of income, and that amount, along with the capital contributions
to NeuCo LLC of its minority interest owners, is shown as "minority interest" on
CRA's balance sheet. All significant intercompany accounts have been eliminated.

CONCENTRATION OF CREDIT RISK

     CRA's accounts receivable base consists of a broad range of clients in a
variety of industries located throughout the United States and in certain other
countries. CRA performs a credit evaluation of each of its clients to minimize
its collectibility risk. Historically, CRA has not experienced significant
write-offs.

     CRA provides an allowance for doubtful accounts to provide for potentially
uncollectible amounts. Activity in the accounts is as follows:

DEFERRED REVENUE

     Deferred revenue represents amounts paid to CRA in advance of services
rendered.

INCOME TAXES

     Until April 28, 1998, CRA had been treated for federal and certain state
income tax purposes as an S Corporation under the Internal Revenue Code of 1986,
as amended (the "Code"). As a result, CRA's stockholders, rather than CRA, were
required to pay federal and certain state income taxes based on CRA's taxable
earnings. CRA filed its returns using the cash method of accounting. Upon
closing of the initial public offering of Common Stock, CRA's status as an S
Corporation terminated. A pro forma provision for income taxes has been
presented as if CRA had been taxed as a C Corporation for the period from
November 30, 1997 to April 28, 1998.

     At the time of the termination of CRA's status as an S Corporation, CRA
recorded a one-time additional provision for income taxes of $1,416,000.

NET INCOME PER SHARE AND PRO FORMA NET INCOME PER SHARE

     Basic earnings per share represents net income divided by the weighted
average shares of Common Stock outstanding during the period. Weighted average
shares used in diluted earnings per share for fiscal 1998 include 49,452 of
Common Stock equivalents arising from stock options using the treasury stock
method.

     Pro forma net income per share is computed using pro forma net income and
the pro forma weighted average number of shares of Common Stock. The weighted
average number of shares of Common Stock for the purpose of computing pro forma
net income per share has been increased by the number of shares that would be
required to pay a dividend in the amount of $2,400,000 that was paid upon the
completion of the initial public offering.

STOCK BASED COMPENSATION

     CRA has elected to follow Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees," in accounting for its stock-based
compensation plans for employees, rather than the alternative fair value
accounting method provided for under SFAS No. 123, "Accounting for Stock-Based
Compensation," as this alternative requires the use of option valuation models
that were not developed for use in valuing stock options. CRA accounts for its
stock-based compensation for non-employees under SFAS No. 123.

FOREIGN CURRENCY TRANSLATION

     In accordance with SFAS No. 52, "Foreign Currency Translation," balance
sheet accounts of CRA's foreign subsidiary are translated into United States
dollars at year end exchange rates. Operating accounts are translated at average
exchange rates for each year. Net translation gains or losses for the fiscal
year ended November 28, 1998 were not significant.

ACCOUNTING PRONOUNCEMENTS

     In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income," and SFAS No. 131, "Disclosures About Segments of an Enterprise and
Related Information." Both SFAS No. 130 and SFAS No. 131 will become effective
for CRA during the fiscal year beginning November 29, 1998. CRA believes that
the adoption of these new accounting standards will not have a material impact
on CRA's consolidated financial statements.

     In December 1997, the Accounting Standards Executive Committee of the
American Institute of Certified Public Accountants issued a Statement of
Position (SOP), "Reporting on the Costs of Start-up Activities," which will
require companies upon adoption to expense start-up costs, including
organization costs, as incurred. In addition, the SOP will require companies
upon adoption to write off as a cumulative change in accounting principle any
previously recorded start-up or organization costs. The SOP is effective for
fiscal years beginning after December 15, 1998. At November 28, 1998, CRA had
deferred start-up costs of $51,000. CRA believes that the adoption of this SOP
will not have a material impact on CRA's consolidated financial statements.

     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities," which requires all derivatives to be
recorded on the balance sheet at fair market value and establishes special
accounting for certain types of hedges. CRA does not engage in any derivative
instruments or hedging activities. The Statement is effective for fiscal years
beginning after June 15, 1999; however, earlier adoption is allowed.

</TABLE>

4. NOTES PAYABLE TO FORMER STOCKHOLDERS

     Notes payable to former stockholders represent amounts owed by CRA to
former stockholders in connection with CRA's repurchase of shares of Common
Stock from such stockholders upon their separation from CRA pursuant to an Exit
Agreement.

     Under the Exit Agreement, CRA repurchased shares of Common Stock from
certain stockholders at a purchase price based upon a formula that uses the book
value of CRA at the date the stockholder separates from CRA (the "Fixed Amount")
and an amount (the "Contingent Pay-Out Amount") equal to the stockholder's pro
rata portion of 25% of CRA's earnings before bonuses, supplemental compensation
and amortization of goodwill, if any, for each of the five fiscal years
commencing with the fiscal year in which the repurchase was made. The Fixed
Amount is payable in three equal installments, and the Contingent Pay-Out Amount
is payable in five equal annual installments. The Fixed Amount bears interest at
an average prime rate (8.13% at November 28, 1998) determined in accordance with
the terms of the Exit Agreement.

     For financial reporting purposes, CRA initially estimates the Contingent
Pay-Out Amount owed to each former stockholder for the full five year payment
period based on the actual amount of the contingent payment for the first year.
In subsequent years, CRA adjusts the estimate annually based on actual amounts
of the contingent payment for all preceding years. The related adjustments are
made to treasury stock and additional paid in capital and, to the extent
additional paid in capital is not available, retained earnings. Annual principal
payments to former stockholders are estimated as of November 28, 1998 to be:
$339,000 in fiscal 1999; $307,000 in fiscal 2000; $149,000 in fiscal 2001 and
$86,000 in fiscal 2002. CRA believes the recorded value of the notes payable to
former stockholders approximates fair market value.

5. FINANCING ARRANGEMENTS

     CRA has a line of credit which permits borrowings of up to $2.0 million
with interest at the bank's base rate (7.75% at November 28, 1998) and is
secured by CRA's accounts receivable. The terms of the line of credit include
certain operating and financial covenants. No borrowings were outstanding as of
November 28, 1998.

6. EMPLOYEE BENEFIT PLANS

     CRA maintains a profit-sharing retirement plan that covers substantially
all full-time employees. Contributions are made at the discretion of CRA and its
subsidiaries and cannot exceed the maximum amount deductible under applicable
provisions of the Code. Contributions were approximately $1.1 million in fiscal
1996, approximately $1.2 million in fiscal 1997 and $1.0 million in fiscal 1998.

7. SUPPLEMENTAL COMPENSATION

     CRA currently has a bonus program which awards discretionary bonuses based
on CRA's revenues, profitability and individual performance. Amounts paid under
this bonus program are included in costs of

                                      F-10

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

services. Prior to the beginning of fiscal 1998, CRA also had another bonus
program, which consisted of discretionary payments to officers and certain
outside experts based primarily on CRA's cash flows. These bonus payments are
shown as supplemental compensation in CRA's statements of income. The Plan was
discontinued at the end of fiscal 1997.

8. LEASES

     At November 28, 1998, the minimum rental commitments under all
noncancellable operating leases with initial or recurring terms of more than one
year were as follows (in thousands):

     Rent expense amounted to approximately $1.5 million in fiscal 1996, $1.8
million in fiscal 1997 and $2.3 million in fiscal 1998.

9. NOTES RECEIVABLE FROM STOCKHOLDERS

     CRA has a policy requiring that each of its officers have an equity
interest in CRA. CRA sold shares of Common Stock to new or existing members of
the management team at the fair market value of the Common Stock on the date of
purchase as determined by CRA's Board of Directors. A portion of the purchase
price is payable at the time of purchase, and the remainder is payable in
installments over a period of five years.

     In 1998, CRA collected $381,000 and declared dividends in the amount of
$830,000 in exchange for the notes receivable.

11. COMMON STOCK

     On March 31, 1998, CRA's Board of Directors authorized (i) the declaration
of a 52-for-1 stock split to be effected in the form of a dividend of 51 shares
of Common Stock per share of Common Stock outstanding

                                      F-11
<PAGE>   57
                     CHARLES RIVER ASSOCIATES INCORPORATED

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

before the closing of the Offering and (ii) an increase in the number of shares
of authorized Common Stock to 25,000,000. The accompanying consolidated
financial statements have been adjusted retroactively to give effect to these
actions for all periods presented.

     In April 1998, CRA completed its initial public offering (the "Offering"),
issuing 1,796,875 shares of Common Stock for proceeds of $29,506,000, net of
offering costs.

     In 1998, CRA and each person who was a stockholder of CRA before the
closing of the Offering elected to amend and restate the Exit Agreement (as so
amended and restated, the "Stock Restriction Agreement"). The Stock Restriction
Agreement prohibits each such pre-Offering stockholder from selling or otherwise
transferring shares of Common Stock held immediately before the Offering without
the consent of the Board of Directors of CRA for two years after the Offering.
In addition, the Stock Restriction Agreement will allow CRA to repurchase a
portion of such stockholder's shares of Common Stock at a percentage of market
value should the stockholder leave CRA (other than for death or retirement for
disability).

12. STOCK-BASED COMPENSATION

     During 1998, CRA adopted the 1998 Incentive and Nonqualified Stock Option
Plan, which provides for the granting of options to purchase up to 970,000
shares of Common Stock. Options are to be granted at an exercise price equal to
the fair market value of the shares of Common Stock at the date of the grant,
and vesting terms are determined at the discretion of the Board of Directors.
All options terminate ten years after the date of grant. A summary of option
activity is as follows:

</TABLE>

     Options granted during fiscal 1998 range from immediate vesting to vesting
at various rates over five years. The weighted average fair market value of the
options granted in 1998 was $9.18.

     Pro forma information regarding net income and earnings per share is
required by SFAS No. 123 and has been determined if CRA had accounted for its
employee stock options under the fair value method of that statement. The fair
market value of the stock options at the date of grant was estimated using the
Black-Scholes option pricing model with the following weighted average
assumptions for fiscal 1998: risk-free interest rate of approximately 5.6%, the
volatility factor of the expected market price of CRA's Common Stock was 62% and
the weighted average expected life was 4.54 years. CRA does not expect to pay
dividends in the foreseeable future.

     The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options, which have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions, including the expected stock price
volatility. Because CRA's employee stock options have characteristics
significantly different from those of traded options, and because changes in the
subjective input assumptions can materially affect the fair value estimate, in
management's opinion, the existing models do not necessarily provide a reliable
single measure of fair value of its employee stock options.

     For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. CRA's pro
forma information is as follows (in thousands, except for earnings per share
information):

<S>                                                           <C>

Diluted earnings per share -- pro forma.....................  $ 0.80
</TABLE>

     The effect on fiscal year 1998 pro forma net income and earnings per share
of expensing the fair value of stock options is not necessarily representative
of the effects on reported results for future years as fiscal 1998 only includes
one year of option grants under CRA's Plan.

     CRA has adopted the 1998 Employee Stock Purchase Plan (the "Stock Purchase
Plan"). The Stock Purchase Plan authorizes the issuance of up to an aggregate of
243,000 shares of Common Stock to participating employees at an amount equal to
85% of fair market value on either the first or the last day of the one year
offering period under the Stock Purchase Plan, whichever is lower. At November
28, 1998, no shares had been issued under the Stock Purchase Plan.

16. SUBSEQUENT EVENT

     On December 15, 1998, CRA completed the acquisition of certain of the
assets and the assumption of certain of the liabilities of The Tilden Group,
LLC, a California limited liability company, for an aggregate $9.6 million in
cash and Common Stock. Tilden is a privately held consulting firm which conducts
economic analyses for litigation, public policy design and business strategy
development. The acquisition of Tilden is being accounted for as a purchase
transaction, and CRA has paid the cash portion of the purchase price from its
working capital.

                     CHARLES RIVER ASSOCIATES INCORPORATED

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)

1. DESCRIPTION OF BUSINESS

     Charles River Associates Incorporated is an economic and business
consulting firm that applies advanced analytic techniques and in-depth industry
knowledge to complex engagements for a broad range of clients. CRA offers two
types of services: legal and regulatory consulting and business consulting.

2. UNAUDITED INTERIM CONSOLIDATED FINANCIAL STATEMENTS AND ESTIMATES

     The consolidated balance sheet as of May 14, 1999, the consolidated
statements of income for the twenty-four weeks ended May 15, 1998 and May 14,
1999 and the consolidated statements of cash flows for the twenty-four weeks
ended May 15, 1998 and May 14, 1999 are unaudited. In the opinion of management,
these statements include all adjustments, consisting only of normal recurring
adjustments, necessary for a fair presentation of CRA's consolidated financial
position, results of operations and cash flows.

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

3. FISCAL YEAR

     CRA's fiscal year ends on the last Saturday in November. Each of CRA's
first, second and fourth quarters includes twelve weeks, and its third quarter
includes sixteen weeks.

4. ACQUISITIONS

     On December 15, 1998, CRA acquired certain assets and assumed certain
liabilities of The Tilden Group, LLC, a consulting firm in the business of
conducting economic analyses for litigation, public policy design, and business
strategy development, for an aggregate of $9.6 million in cash and CRA Common
Stock. CRA accounted for the acquisition as a purchase and has included the
results of the operations of the acquired business in the accompanying
statements of operations from the date of acquisition. CRA has allocated the
excess of the purchase price over the fair value of the net acquired assets to
intangible assets, which consist primarily of goodwill.

     On February 25, 1999, CRA completed the acquisition of certain assets and
the assumption of certain liabilities of the Financial Economic Consulting, or
FinEcon, for an aggregate of $3.2 million in cash and CRA Common Stock. FinEcon
was a privately held consulting firm specializing in financial, economic, and
management consulting in business and commercial litigation. FinEcon is located
in Los Angeles, California, which broadens CRA's West Coast operations and adds
to CRA's established practice in finance. CRA accounted for the acquisition as a
purchase and has included the results of the operations of the acquired business
in the accompanying statements of operations from the date of acquisition. CRA
has allocated the excess of the purchase price over the fair value of the net
acquired assets to intangible assets, which consist primarily of goodwill.

     The results of operations of the acquired companies prior to the dates of
acquisitions would not have a material impact on the consolidated statements of
income for the periods presented and, therefore, pro forma information has not
been presented herein.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

5. INCOME TAXES

     Until April 28, 1998, CRA had been treated for federal and certain state
income tax purposes as an S corporation under the Internal Revenue Code of 1986,
as amended. As a result, CRA's stockholders, rather than CRA, were required to
pay federal and certain state income taxes based on CRA's taxable earnings. CRA
filed its returns using the cash method of accounting. Upon the closing of CRA's
initial public offering of Common Stock in April 1998, CRA's status as an S
corporation terminated.

     At the time of the termination of CRA's status as an S corporation, CRA
recorded a one-time additional provision for income taxes of $1,416,000.

6. NET INCOME PER SHARE

     Basic earnings per share represents net income divided by the weighted
average shares of Common Stock outstanding during the period. Weighted average
shares used in diluted earnings per share include 90,377 Common Stock
equivalents for the twenty-four weeks ended May 14, 1999 arising from stock
options using the treasury stock method.

7. STOCKHOLDERS EQUITY

     In the second quarter of fiscal 1998, CRA completed an initial public
offering of 1,796,875 shares of Common Stock in exchange for $29.5 million of
proceeds, which is net of offering costs.

     Each person who was a stockholder of CRA before the closing of the initial
public offering entered into a Stock Restriction Agreement with CRA, which
prohibits each such person from selling or otherwise transferring shares of
Common Stock held immediately before the initial public offering without the
consent of the Board of Directors of CRA for two years after the initial public
offering. In addition, the Stock Restriction Agreement will allow CRA to
repurchase a portion of such stockholder's shares of Common Stock at a
percentage of market value should the stockholder leave CRA (other than for
death or retirement for disability).

8. ACCOUNTING PRONOUNCEMENTS

     In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income," and SFAS No. 131, "Disclosures About Segments of an Enterprise and
Related Information." Both SFAS No. 130 and SFAS No. 131 are effective for CRA
during the fiscal year beginning November 29, 1998. The adoption of these new
accounting standards has not had a material impact on CRA's consolidated
financial statements.

     In December 1997, the Accounting Standards Executive Committee of the
American Institute of Certified Public Accountants issued a Statement of
Position (SOP), "Reporting on the Costs of Start-up Activities," which will
require companies upon adoption to expense start-up costs, including
organization costs, as incurred. In addition, the SOP will require companies
upon adoption to write off as a cumulative change in accounting principle any
previously recorded start-up or organization costs. The SOP is effective for
fiscal years beginning after December 15, 1998. At May 14, 1999, CRA had
deferred start-up costs of $44,000. CRA believes that the adoption of this SOP
will not have a material impact on CRA's consolidated financial statements.

     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities," which requires all derivatives to be
recorded on the balance sheet at fair market value and establishes special
accounting for certain types of hedges. CRA does not have any derivative
instruments or engage in any hedging activities. The Statement is effective for
fiscal years beginning after June 15, 2000; however, earlier adoption is
allowed.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Article VI.C. of CRA's Amended and Restated Articles of Organization
provides that a director shall not have personal liability to CRA or its
stockholders for monetary damages arising out of the director's breach of
fiduciary duty as a director of CRA, to the maximum extent permitted by
Massachusetts law. Section 13(b)(1 1/2) of Chapter 156B of the Massachusetts
General Laws provides that the articles of organization of a corporation may
state a provision eliminating or limiting the personal liability of a director
to a corporation or its stockholders for monetary damages for breach of
fiduciary duty as a director, provided, however, that such provision shall not
eliminate or limit the liability of a director (a) for any breach of the
director's duty of loyalty to the corporation or its stockholders, (b) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (c) under sections 61 or 62 of Chapter 156B of the
Massachusetts General Laws, which relate to liability for unauthorized
distributions and loans to insiders, respectively, or (d) for any transaction
from which the director derived an improper personal benefit.

     Article VI.D. of CRA's Amended and Restated Articles of Organization
provides that CRA shall, to the fullest extent authorized by Chapter 156B of the
Massachusetts General Laws, indemnify each person who is, or shall have been, a
director or officer of CRA or who is or was a director or employee of CRA and is
serving, or shall have served, at the request of CRA, as a director or officer
of another organization or in any capacity with respect to any employee benefit
plan of CRA, against all liabilities and expenses (including judgments, fines,
penalties, amounts paid or to be paid in settlement, and reasonable attorneys'
fees) imposed upon or incurred by any such person in connection with, or arising
out of, the defense or disposition of any action, suit or other proceeding,
whether civil or criminal, in which they may be involved by reason of being or
having been such a director or officer or as a result of service with respect to
any such employee benefit plan. Section 67 of Chapter 156B of the Massachusetts
General Laws authorizes a corporation to indemnify its directors, officers,
employees and other agents unless such person shall have been adjudicated in any
proceeding not to have acted in good faith in the reasonable belief that such
action was in the best interests of the corporation or, to the extent such
matter related to service with respect to an employee benefit plan, in the best
interests of the participants or beneficiaries of such employee benefit plan.
                                      II-1
<PAGE>   68

     The effect of these provisions would be to permit indemnification by CRA
for, among other liabilities, liabilities arising out of the Securities Act of
1933, as amended (the "Securities Act").

     Section 67 of Chapter 156B of the Massachusetts General Laws also affords a
Massachusetts corporation the power to obtain insurance on behalf of its
directors and officers against liabilities incurred by them in those capacities.
CRA has procured a directors and officers liability and company reimbursement
liability insurance policy that (a) insures directors and officers of CRA
against losses (above a deductible amount) arising from certain claims made
against them by reason of certain acts or omissions of such directors or
officers in their capacity as directors or officers and (b) insures CRA against
losses (above a deductible amount) arising from any such claims, but only if CRA
is required or permitted to indemnify such directors or officers for such losses
under statutory or common law or under provisions of CRA's Amended and Restated
Articles of Organization or Amended and Restated By-Laws.

     Reference is hereby made to Section 8 of the underwriting agreement among
CRA, the selling stockholders and the underwriters, filed as Exhibit 1.1 to this
registration statement, for a description of indemnification arrangements among
CRA, the selling stockholders and the underwriters.

     Reference is hereby made to the indemnity agreement between CRA and the
selling stockholders, filed as Exhibit 99.1 to this registration statement, for
a description of indemnification arrangements by CRA for the benefit of the
selling stockholders.

Exchange Act of 1934 that is incorporated by reference in the registration
statement 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.

     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 foregoing provisions, 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

                                      II-2

connection with the securities being registered, the registrant will, unless in
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.

      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 purpose 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.
