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:

<TABLE>
<CAPTION>
LEGAL AND REGULATORY CONSULTING BUSINESS CONSULTING
------------------------------- -------------------
<S> <C>
- competitive effects of acquisitions - establishment of pricing strategies
- calculations of damages - estimation of market demand
- measurement of market share and market - valuation of intellectual property and
concentration other assets
- liability analysis in securities fraud - assessment of competitors' actions
cases - analysis of new sources of supply
- impact of increased regulation
</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 September 3, 1999, we employed 202 full-time professional
consultants, including 63 consultants with Ph.D.s and 38 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

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

7
<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

8
<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.

9
<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

10
<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.

<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 $4.5 million, after deducting
the estimated underwriting discounts and commissions and estimated offering
expenses payable by CRA and assuming a public offering price of $25.875 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 sale prices for the common stock as reported on the Nasdaq National
Market.

Fourth Quarter (through September 20, 1999)............ 27.000 24.500
</TABLE>

On September 20, 1999, the closing sale price of the common stock as
reported on the Nasdaq National Market was $25.875 per share. On that date, CRA
had approximately 59 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

17
<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.

RECENT FINANCIAL RESULTS

Revenues for the third quarter ended September 3, 1999 were $23.5 million.
This represents an increase of 42.6% as compared to revenues of $16.5 million
for the third quarter of fiscal 1998. The increase in revenues was due primarily
to an increase in the number of employee consultants, an increase in consulting
services for new and existing clients during the period and, to a lesser extent,
increased billing rates of CRA's consultants. Income from operations for the
third quarter of fiscal 1999 was $4.5 million as compared to income from
operations for the third quarter of fiscal 1998 of $2.8 million. Net income for
the third quarter of fiscal 1999 was $2.8 million, or $0.33 per share on a basic
basis and $0.32 per share on a diluted basis. By comparison, net income for the
third quarter of fiscal 1998 was $2.0 million, or $0.24 per share on a basic and
diluted basis. CRA's third quarter consists of 16 weeks; its other three
quarters consist of 12 weeks each.

Information with respect to the third quarter of fiscal 1999 is based upon
CRA's preliminary and unaudited financial statements, which remain subject to
change. The results of operations for the third quarter of fiscal 1999 or any
other quarter are not necessarily indicative of the results to be expected for
any future period.

</TABLE>

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

19
<PAGE> 20

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.

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,

20
<PAGE> 21

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
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

22
<PAGE> 23

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 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.

<PAGE> 24

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 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.

BUSINESS

INTRODUCTION

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>
<CAPTION>
LEGAL AND REGULATORY CONSULTING BUSINESS CONSULTING
------------------------------- -------------------
<S> <C>
- - competitive effects of acquisitions - establishment of pricing strategies
- - calculations of damages - estimation of market demand
- - measurement of market share and market - valuation of intellectual property and
concentration other assets
- - liability analysis in securities fraud - assessment of competitors' actions
cases - analysis of new sources of supply
- - impact of increased regulation
</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 September 3, 1999, CRA employed 202
full-time professional consultants, including 63 consultants with Ph.D.s and 38
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.

25
<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

26
<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 202 consultants as of September 3,
1999, 102 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 selected 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
28
<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

30
<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
31
<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 September 3, 1999, CRA had 202 full-time employee consultants,
consisting of 37 officers, 65 other senior consultants (either principals or
senior associates) and 100 junior consultants (either associates or analysts),
and had over 70 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 102 as of September 3,
1999, 56 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

32
<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
33
<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.

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;

- 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 September 20, 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 September 20, 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
41
<PAGE> 42

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

42
<PAGE> 43

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.

Securities LLC, William Blair & Company, L.L.C. and Salomon Smith Barney Inc.
are the representatives of the underwriters. CRA and the selling stockholders
have entered into a firm commitment underwriting agreement with the
underwriters. Subject to the terms and conditions of the underwriting agreement,
CRA and the selling stockholders have agreed to sell to the underwriters, and
the underwriters have each agreed to purchase, the number of shares of common
stock listed next to its name in the following table.

The underwriters will offer the shares to the public at the price specified
on the cover page of this prospectus. The underwriters may allow to some dealers
a concession of not more than $ per share. The underwriters also may allow,
and any dealers may reallow, a concession of not more than $ per share to
some other dealers. If all the shares are not sold at the public offering price,
the underwriters may change the offering price and the other selling terms. The
common stock is offered subject to a number of conditions, including:

- receipt and acceptance of the common stock by the underwriters

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

The underwriters have an option to buy up to 300,000 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 4,027,379 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.

<PAGE> 45

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 certain 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.

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.

F-7
<PAGE> 54
CHARLES RIVER ASSOCIATES INCORPORATED

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:

</TABLE>

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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

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
<PAGE> 57
CHARLES RIVER ASSOCIATES INCORPORATED

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.

10. NET INCOME PER SHARE AND PRO FORMA NET INCOME PER SHARE

A reconciliation of the shares used in calculating basic, diluted and pro
forma net income is as follows:

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

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>
<CAPTION>
WEIGHTED AVERAGE
OPTIONS EXERCISE PRICE
------- ----------------
<S> <C> <C>
Outstanding at November 29, 1997............................ -- --
Granted..................................................... 352,500 $18.90
Canceled.................................................... (16,500) 18.50
-------
Outstanding at November 28, 1998............................ 336,000 $18.90
Options available for grant................................. 634,000
Options exercisable......................................... 3,500 $23.75
Weighted average remaining contractual life at November 28,
1998...................................................... 9 1/2
years
</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.

F-12
<PAGE> 59
CHARLES RIVER ASSOCIATES INCORPORATED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

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):

<TABLE>
<S> <C>
Net income -- as reported................................... $6,365
Net income -- pro forma..................................... $6,116
Basic and diluted earnings per share -- as reported......... $ 0.84
Basic earnings per share -- pro forma....................... $ 0.81
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.

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.

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> 69

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.

ITEM 17. UNDERTAKINGS.

The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
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
<PAGE> 70

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.

requirements for filing on Form S-3 and has duly caused this registration

BANC OF AMERICA SECURITIES LLC
WILLIAM BLAIR & COMPANY, L.L.C.
SALOMON SMITH BARNEY INC.
As Representatives of the several Underwriters
c/o BANC OF AMERICA SECURITIES LLC
600 Montgomery Street
San Francisco, California 94111

Ladies and Gentlemen:

INTRODUCTORY. Charles River Associates Incorporated, a Massachusetts
corporation (the "Company"), proposes to issue and sell to the several
underwriters named in SCHEDULE A (the "Underwriters") an aggregate of 200,000
shares of its Common Stock, no par value (the "Common Stock"); and the
stockholders of the Company named in SCHEDULE B (collectively, the "Selling
Stockholders") severally propose to sell to the Underwriters an aggregate of
1,800,000 shares of Common Stock. The 200,000 shares of Common Stock to be sold
by the Company and the 1,800,000 shares of Common Stock to be sold by the
Selling Stockholders are collectively called the "Firm Common Shares." In
addition, the Selling Stockholders propose severally to grant to the
Underwriters an option to purchase up to an additional 300,000 shares of Common
Stock, each Selling Stockholder selling up to the amount set forth opposite such
Selling Stockholder's name in Schedule B, all as provided in Section 2. The
additional 300,000 shares to be sold by the Selling Stockholders pursuant to
such option are collectively called the "Optional Common Shares." The Firm
Common Shares and, if and to the extent such option is exercised, the Optional
Common Shares are collectively called the "Common Shares." Banc of America
Securities LLC ("BAS"), William Blair & Company L.L.C. and Salomon Smith Barney
Inc. have agreed to act as representatives of the several Underwriters (in such
capacity, the "Representatives") in connection with the offering and sale of the
Common Shares.

The Company has prepared and filed with the Securities and Exchange
Commission (the "Commission") a registration statement on Form S-3 (File No.
333- 85899), which contains a form of prospectus to be used in connection with
the public offering and sale of the Common Shares. Such registration statement,
as amended, including the financial statements, exhibits and schedules thereto,
in the form in which it was declared effective by the Commission under the
Securities Act of 1933 and the rules and regulations promulgated thereunder
(collectively, the "Securities Act"), including all documents incorporated or
deemed to be incorporated by reference therein and any information deemed to be
a part thereof at the time of effectiveness pursuant to Rule 430A or Rule 434
under the Securities Act is called the "Registration Statement." Any
registration statement filed by the Company pursuant to Rule 462(b) under the
Securities Act, is called the "Rule 462(b) Registration Statement," and from and
after the date and time of filing of the Rule 462(b) Registration Statement the
term "Registration Statement" shall include the Rule 462(b) Registration
Statement. Such prospectus, in the form first used by the Underwriters

- 4 -

<PAGE> 6

to confirm sales of the Common Shares, is called the "Prospectus"; provided,
however, if the Company has, with the consent of BAS, elected to rely upon Rule
434 under the Securities Act, the term "Prospectus" shall mean the Company's
prospectus subject to completion (each, a "preliminary prospectus") dated
_______, 1999 (such preliminary prospectus is called the "Rule 434 preliminary
prospectus"), together with the applicable term sheet (the "Term Sheet")
prepared and filed by the Company with the Commission under Rules 434 and 424(b)
under the Securities Act and all references in this Agreement to the date of the
Prospectus shall mean the date of the Term Sheet. All references in this
Agreement to the Registration Statement, the Rule 462(b) Registration Statement,
a preliminary prospectus, the Prospectus or the Term Sheet, or any amendments or
supplements to any of the foregoing, shall include any copy thereof filed with
the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval
System ("EDGAR"). All references in this Agreement to financial statements and
schedules and other information which is "contained," "included" or "stated" in
the Registration Statement or the Prospectus (and all other references of like
import) shall be deemed to mean and include all such financial statements and
schedules and other information which is or is deemed to be incorporated by
reference in the Registration Statement or the Prospectus, as the case may be;
and all references in this Agreement to amendments or supplements to the
Registration Statement or the Prospectus shall be deemed to mean and include the
filing of any document under the Securities Exchange Act of 1934 and the rules
and regulations promulgated thereunder (collectively, the "Exchange Act"), which
is or is deemed to be incorporated by reference in the Registration Statement or
the Prospectus, as the case may be.

The Company and each of the Selling Stockholders hereby confirm their
respective agreements with the Underwriters as follows:

SECTION 1. REPRESENTATIONS AND WARRANTIES

A. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company
hereby represents, warrants and covenants to each Underwriter as follows:

(a) Compliance with Registration Requirements. The
Registration Statement and any Rule 462(b) Registration Statement have
been declared effective by the Commission under the Securities Act. The
Company has complied to the Commission's satisfaction with all requests
of the Commission for additional or supplemental information. No stop
order suspending the effectiveness of the Registration Statement or any
Rule 462(b) Registration Statement is in effect and no proceedings for
such purpose have been instituted or are pending or, to the best
knowledge of the Company, are contemplated or threatened by the
Commission.

-5-

<PAGE> 7

Each preliminary prospectus and the Prospectus when filed
complied in all material respects with the Securities Act and, if filed
by electronic transmission pursuant to EDGAR (except as may be
permitted by Regulation S-T under the Securities Act), was identical to
the copy thereof delivered to the Underwriters for use in connection
with the offer and sale of the Common Shares. Each of the Registration
Statement, any Rule 462(b) Registration Statement and any
post-effective amendment thereto, at the time it became effective and
at all subsequent times, complied and will comply in all material
respects with the Securities Act and did not and will not contain any
untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements
therein not misleading. The Prospectus, as amended or supplemented, as
of its date and at all subsequent times, did not and will not contain
any untrue statement of a material fact or omit to state a material
fact necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading. The
representations and warranties set forth in the two immediately
preceding sentences do not apply to statements in or omissions from the
Registration Statement, any Rule 462(b) Registration Statement, or any
post-effective amendment thereto, or the Prospectus, or any amendments
or supplements thereto, made in reliance upon and in conformity with
information relating to any Underwriter furnished to the Company in
writing by the Representatives expressly for use therein. There are no
contracts or other documents required to be described in the Prospectus
or to be filed as exhibits to the Registration Statement which have not
been described or filed as required.

(b) Offering Materials Furnished to Underwriters. The Company
has delivered to each Representative one complete manually signed copy
of the Registration Statement and of each consent and certificate of
experts filed as a part thereof, and conformed copies of the
Registration Statement (without exhibits) and preliminary prospectuses
and the Prospectus, as amended or supplemented, in such quantities and
at such places as the Representatives have reasonably requested for
each of the Underwriters.

(c) Distribution of Offering Material By the Company. The
Company has not distributed and will not distribute, prior to the later
of the Second Closing Date (as defined below) and the completion of the
Underwriters' distribution of the Common Shares, any offering material
in connection with the offering and sale of the Common Shares other
than a preliminary prospectus, the Prospectus or the Registration
Statement.

(d) The Underwriting Agreement. This Agreement has been duly
authorized, executed and delivered by, and is a valid and binding
agreement of, the Company, enforceable in accordance with its terms,
except as rights to

-6-

<PAGE> 8

indemnification or contribution hereunder may be limited by applicable
law and except as the enforcement hereof may be limited by bankruptcy,
insolvency, reorganization, moratorium or other similar laws relating
to or affecting the rights and remedies of creditors or by general
equitable principles.

(e) Authorization of the Common Shares. The Common Shares to
be purchased by the Underwriters from the Company have been duly
authorized for issuance and sale pursuant to this Agreement and, when
issued and delivered by the Company pursuant to this Agreement, will be
validly issued, fully paid and nonassessable.

(f) No Applicable Registration or Other Similar Rights. There
are no persons with registration or other similar rights to have any
equity or debt securities registered for sale under the Registration
Statement or included in the offering contemplated by this Agreement,
except for such rights as have been duly waived or complied with.

(g) No Material Adverse Change. Except as otherwise disclosed
in the Prospectus, subsequent to the respective dates as of which
information is given in the Prospectus: (i) there has been no material
adverse change, or any development that could reasonably be expected to
result in a material adverse change, in the condition, financial or
otherwise, or in the earnings, business, operations or prospects,
whether or not arising from transactions in the ordinary course of
business, of the Company and its subsidiaries (the "Subsidiaries"),
considered as one entity (any such change is called a "Material Adverse
Change"); (ii) the Company and the Subsidiaries, considered as one
entity, have not incurred any material liability or obligation,
indirect, direct or contingent, not in the ordinary course of business
nor entered into any material transaction or agreement not in the
ordinary course of business; and (iii) there has been no dividend or
distribution of any kind declared, paid or made by the Company or,
except for dividends paid to the Company, by a Subsidiary on any class
of capital stock or repurchase or redemption by the Company or any
Subsidiary of any class of capital stock.

(h) Independent Accountants. Ernst & Young LLP, who have
expressed their opinion with respect to the financial statements (which
term as used in this Agreement includes the related notes thereto) and
supporting schedules filed with the Commission as a part of the
Registration Statement and included in the Prospectus, are independent
public or certified public accountants as required by the Securities
Act and the Securities Exchange Act of 1934, as amended (the "Exchange
Act").

-7-

<PAGE> 9

(i) Preparation of the Financial Statements. The financial
statements filed with the Commission as a part of the Registration
Statement and included in the Prospectus present fairly the
consolidated financial position of the Company and the Subsidiaries as
of and at the dates indicated and the results of their operations and
cash flows for the periods specified. The supporting schedules, if any,
included in the Registration Statement present fairly the information
required to be stated therein. Such financial statements and supporting
schedules have been prepared in conformity with generally accepted
accounting principles applied on a consistent basis throughout the
periods involved, except as may be expressly stated in the related
notes thereto. No other financial statements or supporting schedules
are required to be included in the Registration Statement. The
financial data set forth in the Prospectus under the captions
"Prospectus Summary--Summary Consolidated Financial Data," "Selected
Consolidated Financial Data" and "Capitalization" fairly present the
information set forth therein on a basis consistent with that of the
audited financial statements contained in the Registration Statement.

(j) Incorporation and Good Standing of the Company and the
Subsidiaries. The Company has been duly incorporated and is validly
existing as a corporation in good standing under the laws of the
Commonwealth of Massachusetts and has corporate power and authority to
own, lease and operate its properties and to conduct its business as
described in the Prospectus and to enter into and perform its
obligations under this Agreement. Each Subsidiary has been duly
organized and is validly existing as a corporation or limited liability
company in good standing under the laws of the jurisdiction of its
organization and has power and authority to own, lease and operate its
properties and to conduct its business as described in the Prospectus.
Each of the Company and the Subsidiaries is duly qualified to transact
business and is in good standing in each jurisdiction in which such
qualification is required, whether by reason of the ownership or
leasing of property or the conduct of business, except for such
jurisdictions where the failure to so qualify or to be in good
standing would not, individually or in the aggregate, result in a
Material Adverse Change. The Company is the legal and beneficial owner
of the capital stock or membership interest in each Subsidiary, as
described in the Registration Statement. The Company owns its capital
stock or membership interest in each Subsidiary free and clear of any
security interest, mortgage, pledge, lien, encumbrance or claim.
Except as described in the Prospectus, the Company has no obligation
to contribute capital to any Subsidiary pursuant to the organizational
documents, operating agreement or certificate of formation of such
Subsidiary or any contractual arrangement with any third party. The
Company does not own or control, directly or indirectly, any
corporation, association or other entity other than the Subsidiaries.

<PAGE> 10

(k) Capitalization and Other Capital Stock Matters. The
authorized, issued and outstanding capital stock of the Company as of
May 14, 1999 was as set forth in the Prospectus under the caption
"Capitalization." The Common Stock (including the Common Shares)
conforms in all material respects to the description thereof contained
in the Prospectus. All of the issued and outstanding shares of Common
Stock (including the shares of Common Stock owned by Selling
Stockholders) have been duly authorized and validly issued, are
(except, in the case of shares purchased by officers of the Company
under agreements which provide for the purchase price to be paid in
installments, to the extent of the installments which are not yet due
and payable) fully paid and nonassessable and have been issued in
compliance with federal and state securities laws. None of the
outstanding shares of Common Stock were issued in violation of any
preemptive rights, rights of first refusal or other similar rights to
subscribe for or purchase securities of the Company. There are no
authorized or outstanding options, warrants, preemptive rights, rights
of first refusal or other rights to purchase, or equity or debt
securities convertible into or exchangeable or exercisable for, any
capital stock of the Company or any Subsidiary other than those
accurately described in the Prospectus. The description of the
Company's stock option, stock bonus and other stock plans or
arrangements, and the options or other rights granted thereunder, set
forth in the Prospectus is an accurate and fair description in all
material respects of such plans, arrangements, options and rights.

(l) Exchange Act and Nasdaq National Market Listing. The
Common Stock (including the Common Shares) is registered pursuant to
Section 12(g) of the Exchange Act and is listed on the Nasdaq National
Market and the Company has taken no action designed to, or likely to
have the effect of, terminating the registration of the Common Stock
under the Exchange Act or delisting the Common Stock from the Nasdaq
National Market, nor has the Company received any notification that
the Commission or the National Association of Securities Dealers, Inc.
(the "NASD") is contemplating terminating such registration or
listing.

(m) Non-Contravention of Existing Instruments; No Further
Authorizations or Approvals Required. Neither the Company nor any
Subsidiary is in violation of its charter or by-laws or is in default
(or, with the giving of notice or lapse of time, would be in default)
("Default") under any indenture, mortgage, loan or credit agreement,
note, contract, franchise, lease or other instrument to which the
Company or such Subsidiary is a party or by which it or any of them may
be bound or to which any of the property or assets of the Company or
such Subsidiary is subject (each, an "Existing Instrument"), except for
such Defaults as would not, individually or in the aggregate, result in
a Material Adverse Change. The Company's execution, delivery and
performance of this Agreement and consummation of the transactions
contemplated hereby and by

-9-

<PAGE> 11

the Prospectus (i) have been duly authorized by all necessary
corporate action and will not result in any violation of the
provisions of the charter or by-laws of the Company or any Subsidiary,
(ii) will not conflict with or constitute a breach of, or Default
under, or result in the creation or imposition of any lien, charge or
encumbrance upon any property or assets of the Company or any
Subsidiary pursuant to, or require the consent of any other party to,
any Existing Instrument, except for such conflicts, breaches,
Defaults, liens, charges or encumbrances (i) as to which the Company
has obtained prior to the date hereof a valid waiver or consent, a
copy of which has been delivered to counsel for the Underwriters, or
(ii) as would not, individually or in the aggregate, result in a
Material Adverse Change and (iii) will not result in any violation of
any law, administrative regulation or administrative or court decree
applicable to the Company or any Subsidiary. No consent, approval,
authorization or other order of, or registration or filing with, any
court or other governmental or regulatory authority or agency, is
required for the Company's execution, delivery and performance of this
Agreement and consummation of the transactions contemplated hereby and
by the Prospectus, except such as have been obtained or made by the
Company and are in full force and effect under the Securities Act or
applicable state securities or blue sky laws and from the NASD.

(n) No Material Actions or Proceedings. There are no legal or
governmental actions, suits or proceedings pending or, to the best of
the Company's knowledge, threatened (i) against the Company or any
Subsidiary, (ii) which has as the subject thereof any officer or
director of, or property owned or leased by, the Company or any
Subsidiary or (iii) relating to environmental or discrimination
matters, where in any such case (A) there is a reasonable possibility
that such action, suit or proceeding might be determined adversely to
the Company or any Subsidiary and (B) any such action, suit or
proceeding, if so determined adversely, would reasonably be expected
to result in a Material Adverse Change or adversely affect the
consummation of the transactions contemplated by this Agreement. No
material labor dispute with the employees of the Company or any
Subsidiary exists or, to the best of the Company's knowledge, is
threatened or imminent.

(o) Intellectual Property Rights. The Company and each Subsidiary
own or possess sufficient trademarks, trade names, patent rights,
copyrights, licenses, approvals, trade secrets and other similar
rights (collectively, "Intellectual Property Rights") reasonably
necessary to conduct their businesses as now conducted; and the
expected expiration of any of such Intellectual Property Rights would
not result in a Material Adverse Change. Neither the Company nor any
Subsidiary has received any notice of infringement or conflict with
asserted Intellectual Property Rights of others, which

-10-

<PAGE> 12

infringement or conflict, if the subject of an unfavorable decision,
would result in a Material Adverse Change.

(p) All Necessary Permits, etc. The Company and each Subsidiary
possess such valid and current certificates, authorizations or permits
issued by the appropriate state, federal or foreign regulatory
agencies or bodies necessary to conduct their respective businesses,
except where any failure to possess the same, individually or in the
aggregate, would not result in a Material Adverse Change, and neither
the Company nor any Subsidiary has received any notice of proceedings
relating to the revocation or modification of, or non-compliance with,
any such certificate, authorization or permit which, singly or in the
aggregate, if the subject of an unfavorable decision, ruling or
finding, could result in a Material Adverse Change.

(q) Title to Properties. The Company and each Subsidiary have
good and marketable title to all the properties and assets reflected
as owned in the financial statements referred to in Section 1(A)(i)
above (or elsewhere in the Prospectus), in each case free and clear of
any security interests, mortgages, liens, encumbrances, equities,
claims and other defects, except such as are disclosed in the
Prospectus or as do not materially and adversely affect the value of
such property and do not materially interfere with the use made or
proposed to be made of such property by the Company or such
Subsidiary. The real property, improvements, equipment and personal
property held under lease by the Company or any Subsidiary are held
under valid and enforceable leases, with such exceptions as are not
material and do not materially interfere with the use made or proposed
to be made of such real property, improvements, equipment or personal
property by the Company or such Subsidiary.

(r) Tax Law Compliance. The Company and each Subsidiary have
filed all necessary federal, state and foreign income and franchise
tax returns and have paid all taxes due and payable by any of them
and, if due and payable, any related or similar assessment, fine or
penalty levied against any of them, except as may be being contested
in good faith and by appropriate proceedings. The Company has made
adequate charges, accruals and reserves in the applicable financial
statements referred to in Section 1(A)(i) above in respect of all
federal, state and foreign income and franchise taxes for all periods
as to which the tax liability of the Company or any Subsidiary has not
been finally determined.

(s) Company Not an "Investment Company". The Company has been
advised of the rules and requirements under the Investment Company Act
of 1940, as amended (the "Investment Company Act"). The Company is
not, and after receipt of payment for the Common Shares will not be,
an

-11-

<PAGE> 13

"investment company" within the meaning of the Investment Company Act
and will conduct its business in a manner so that it will not become
subject to the Investment Company Act.

(t) Insurance. The Company and each Subsidiary are insured by
recognized, financially sound and reputable institutions with policies
in such amounts and with such deductibles and covering such risks as
are generally deemed adequate and customary for their businesses
including, but not limited to, policies covering real and personal
property owned or leased by the Company and any Subsidiary against
theft, damage, destruction, acts of vandalism and earthquakes. The
Company has no reason to believe that it or the Subsidiaries will not
be able (i) to renew its existing insurance coverage as and when such
policies expire or (ii) to obtain comparable coverage from similar
institutions as may be necessary or appropriate to conduct its
business as now conducted and at a cost that would not result in a
Material Adverse Change. Since November 27, 1993, neither the Company
nor any Subsidiary has been denied any insurance coverage which it has
sought or for which it has applied.

(u) No Price Stabilization or Manipulation. The Company has not
taken and will not take, directly or indirectly, any action designed
to or that might be reasonably expected to cause or result in
stabilization or manipulation of the price of the Common Stock to
facilitate the sale or resale of the Common Shares.

(v) Related Party Transactions. There are no business
relationships or related-party transactions involving the Company or
any Subsidiary or any other person required to be described in the
Prospectus which have not been described as required.

(w) No Unlawful Contributions or Other Payments. Neither the
Company nor any Subsidiary nor, to the best of the Company's
knowledge, any employee or agent of the Company or any Subsidiary, has
made any contribution or other payment to any official of, or
candidate for, any federal, state or foreign office in violation of
any law or of the character required to be disclosed in the
Prospectus.

(x) ERISA Compliance. The Company and each Subsidiary and any
"employee benefit plan" (as defined under the Employee Retirement
Income Security Act of 1974, as amended, and the regulations and
published interpretations thereunder (collectively, "ERISA"))
established or maintained by the Company, any Subsidiary or their
"ERISA Affiliates" (as defined below) are in compliance in all
material respects with ERISA. "ERISA Affiliate" means, with respect to
the Company or any Subsidiary, any member of any group of

-12-

<PAGE> 14

organizations described in Sections 414(b),(c),(m) or (o) of the
Internal Revenue Code of 1986, as amended, and the regulations and
published interpretations thereunder (the "Code") of which the Company
or any Subsidiary is a member. No "reportable event" (as defined under
ERISA) has occurred or is reasonably expected to occur with respect to
any "employee benefit plan" established or maintained by the Company,
any Subsidiary or any of their ERISA Affiliates. No "employee benefit
plan" established or maintained by the Company, any Subsidiary or any
of their ERISA Affiliates, if such "employee benefit plan" were
terminated, would have any "amount of unfunded benefit liabilities"
(as defined under ERISA). Neither the Company, any Subsidiary nor any
of their ERISA Affiliates has incurred or reasonably expects to incur
any liability under (i) Title IV of ERISA with respect to termination
of, or withdrawal from, any "employee benefit plan" or (ii) Sections
412, 4971, 4975 or 4980B of the Code. Each "employee benefit plan"
established or maintained by the Company, any Subsidiary or any of
their ERISA Affiliates that is intended to be qualified under Section
401(a) of the Code is so qualified and nothing has occurred, whether
by action or failure to act, which would cause the loss of such
qualification.

(y) Exchange Act Compliance. The Company has filed on a timely
basis all reports and other documents required to be filed by it under
the Exchange Act. All such reports and documents, as well as any such
reports and documents filed by the Company from the date of this
Agreement through the Second Closing Date, at the time they were or
hereafter are filed with the Commission, complied and will comply in
all material respects with the requirements of the Exchange Act, and
when filed, did not or will not contain an untrue statement of the
material fact or omit to state a material fact required to be stated
therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.

Any certificate signed by an officer of the Company and delivered
to the Representatives or to counsel for the Underwriters on the First Closing
Date or the Second Closing Date shall be deemed to be a representation and
warranty by the Company to each Underwriter as to the matters set forth therein.

B. REPRESENTATIONS AND WARRANTIES OF THE SELLING STOCKHOLDERS. Each
Selling Stockholder, severally and not jointly, hereby represents, warrants and
covenants to each Underwriter as follows:

date hereof, a copy of which has been delivered to counsel for the

(h) Disclosure Made by Such Selling Stockholder in the
Prospectus. All information furnished by or on behalf of such Selling
Stockholder in writing expressly for use in the Registration Statement
and Prospectus is, and on the First Closing Date and the Second
Closing Date will be, true, correct, and complete in all material
respects, and does not, and on the First Closing Date and the Second
Closing Date will not, contain any untrue statement of a material fact
or omit to state any material fact necessary to make such information
not misleading. Such Selling Stockholder confirms as accurate the

(i) No Price Stabilization or Manipulation. Such Selling
Stockholder has not taken and will not take, directly or indirectly,
any action designed to or that might be reasonably expected to cause

Stock to facilitate the sale or resale of the Common Shares.

(j) Registration Statement and Prospectus. Such Selling

Stock by any information concerning the Company which is not set forth
in the Registration Statement and the Prospectus.

Any certificate signed by or on behalf of any Selling Stockholder
and delivered to the Representatives or to counsel for the Underwriters on the

representation and warranty by such Selling Stockholder to each Underwriter as
to the matters covered thereby.

SECTION 2. PURCHASE, SALE AND DELIVERY OF THE COMMON SHARES.

The Firm Common Shares. Upon the terms herein set forth, (i) the
Company agrees to issue and sell to the several Underwriters an aggregate of
200,000 Firm Common Shares and (ii) the Selling Stockholders agree, severally
and not jointly, to sell to the several Underwriters an aggregate of 1,800,000
Firm Common Shares, each Selling Stockholder selling the number of Firm Common
Shares set forth opposite such Selling Stockholder's name on SCHEDULE B. On the
basis of the representations, warranties and agreements herein contained, and
upon the terms but subject to the conditions herein set forth, the Underwriters
agree, severally and not jointly, to purchase from the Company and the Selling
Stockholders the respective number of Firm Common Shares set forth opposite
their names on SCHEDULE A. The purchase price per Firm Common Share to be paid
by the several Underwriters to the Company and the Selling Stockholders shall be
$______ per share.

The First Closing Date. Delivery of certificates for the Firm Common
Shares to be purchased by the Underwriters and payment therefor shall be made at
the offices

-16-

<PAGE> 18

of BAS, 600 Montgomery Street, San Francisco, California (or such other place as
may be agreed to by the Company and the Representatives) at 6:00 a.m. San
Francisco time, on ________, 1999 or such other time and date not later than
10:30 a.m. San Francisco time, on _____, 1999 as the Representatives shall
designate by notice to the Company (the time and date of such closing are called
the "First Closing Date"). The Company and the Selling Stockholders hereby
acknowledge that circumstances under which the Representatives may provide
notice to postpone the First Closing Date as originally scheduled include, but
are in no way limited to, any determination by the Company or the
Representatives to recirculate to the public copies of an amended or
supplemented Prospectus or a delay as contemplated by the provisions of Section
10.

The Optional Common Shares; the Second Closing Date. In addition, on
the basis of the representations, warranties and agreements herein contained,
and upon the terms but subject to the conditions herein set forth, the Selling
Stockholders hereby grant, severally and not jointly, an option to the several
Underwriters to purchase, severally and not jointly, up to an aggregate of
300,000 Optional Common Shares from the Selling Stockholders at the purchase
price per share to be paid by the Underwriters for the Firm Common Shares. The
option granted hereunder is for use by the Underwriters solely in covering any
over-allotments in connection with the sale and distribution of the Firm Common
Shares. The option granted hereunder may be exercised at any time (but not more
than once) upon notice by the Representatives to the Company and the Selling
Stockholders, which notice may be given at any time within 30 days from the date
of this Agreement. Such notice shall set forth (i) the aggregate number of
Optional Common Shares as to which the Underwriters are exercising the option,
(ii) the names and denominations in which the certificates for the Optional
Common Shares are to be registered and (iii) the time, date and place at which
such certificates are to be delivered (which time and date may be simultaneous
with, but not earlier than, the First Closing Date; and in such case the term
"First Closing Date" shall refer to the time and date of delivery of
certificates for the Firm Common Shares and the Optional Common Shares). Such
time and date of delivery, if subsequent to the First Closing Date, is called
the "Second Closing Date" and shall be determined by the Representatives and
shall not be earlier than three nor later than five full business days after
delivery of such notice of exercise. If any Optional Common Shares are to be
purchased, (a) each Underwriter agrees, severally and not jointly, to purchase
the number of Optional Common Shares (subject to such adjustments to eliminate
fractional shares as the Representatives may determine) that bears the same
proportion to the total number of Optional Common Shares to be purchased as the
number of Firm Common Shares set forth on SCHEDULE A opposite the name of such
Underwriter bears to the total number of Firm Common Shares and (b) each Selling
Stockholder agrees, severally and not jointly, to sell the number of Optional
Common Shares (subject to such adjustments to eliminate fractional shares as the
Representatives may determine) that bears the same proportion to the total
number of Optional Common Shares to be sold

-17-

<PAGE> 19

as the number of Optional Common Shares set forth in SCHEDULE B opposite the
name of such Selling Stockholder bears to the total number of Optional Common
Shares. The Representatives may cancel the option at any time prior to its
expiration by giving written notice of such cancellation to the Company and the
Selling Stockholders.

Public Offering of the Common Shares. The Representatives hereby advise
the Company and the Selling Stockholders that the Underwriters intend to offer
for sale to the public, as described in the Prospectus, their respective
portions of the Common Shares as soon after this Agreement has been executed and
the Registration Statement has been declared effective as the Representatives,
in their sole judgment, have determined is advisable and practicable.

Payment for the Common Shares. Payment for the Common Shares to be sold
by the Company shall be made at the First Closing Date by wire transfer of
immediately available funds to the order of the Company. Payment for the Common
Shares to be sold by the Selling Stockholders shall be made at the First Closing
Date (and, if applicable, at the Second Closing Date) by wire transfer of
immediately available funds to the order of the Custodian.

It is understood that the Representatives have been
authorized, for their own account and the accounts of the several Underwriters,
to accept delivery of and give receipt for, and make payment of the purchase
price for, the Firm Common Shares and any Optional Common Shares the
Underwriters have agreed to purchase. BAS, individually and not as a
Representative of the Underwriters, may (but shall not be obligated to) make
payment for any Common Shares to be purchased by any Underwriter whose funds
shall not have been received by the Representatives by the First Closing Date or
the Second Closing Date, as the case may be, for the account of such
Underwriter, but any such payment shall not relieve such Underwriter from any of
its obligations under this Agreement.

Each Selling Stockholder hereby agrees that (i) it will pay
all stock transfer taxes, stamp duties and other similar taxes, if any, payable
upon the sale or delivery of the Common Shares to be sold by such Selling
Stockholder to the several Underwriters, or otherwise in connection with the
performance of such Selling Stockholder's obligations hereunder and (ii) the
Custodian is authorized to deduct for such payment any such amounts from the
proceeds to such Selling Stockholder hereunder and to hold such amounts for the
account of such Selling Stockholder with the Custodian under the Custody
Agreement.

Delivery of the Common Shares. The Company and the Selling Stockholders
shall, severally and not jointly, deliver, or cause to be delivered, to the
Representatives for the accounts of the several Underwriters certificates for
the Firm Common Shares to be sold by them at the First Closing Date, against the
irrevocable

-18-

<PAGE> 20

release of a wire transfer of immediately available funds for the amount of the
purchase price therefor. The Company and the Selling Stockholders shall,
severally and not jointly, also deliver, or cause to be delivered, to the
Representatives for the accounts of the several Underwriters, certificates for
the Optional Common Shares the Underwriters have agreed to purchase from them at
the First Closing Date or the Second Closing Date, as the case may be, against
the irrevocable release of a wire transfer of immediately available funds for
the amount of the purchase price therefor. The certificates for the Common
Shares shall be in definitive form and registered in such names and
denominations as the Representatives shall have requested at least two full
business days prior to the First Closing Date (or the Second Closing Date, as
the case may be) and shall be made available for inspection on the business day
preceding the First Closing Date (or the Second Closing Date, as the case may
be) at a location in New York City as the Representatives may designate. Time
shall be of the essence, and delivery at the time and place specified in this
Agreement is a further condition to the obligations of the Underwriters.

Delivery of Prospectus to the Underwriters. Not later than 12:00 p.m.
San Francisco time on the second business day following the date the Common
Shares are released by the Underwriters for sale to the public, the Company
shall deliver or cause to be delivered copies of the Prospectus in such
quantities and at such places as the Representatives shall request.

SECTION 3. ADDITIONAL COVENANTS.

A. COVENANTS OF THE COMPANY. The Company further covenants and
agrees with each Underwriter as follows:

(a) Representatives' Review of Proposed Amendments and
Supplements. During such period beginning on the date hereof and
ending on the later of the First Closing Date or such date, as in the
opinion of counsel for the Underwriters, the Prospectus is no longer
required by law to be delivered in connection with sales by an
Underwriter or dealer (the "Prospectus Delivery Period"), prior to
amending or supplementing the Registration Statement (including any
registration statement filed under Rule 462(b) under the Securities
Act) or the Prospectus (including any amendment or supplement through
incorporation by reference of any report filed under the Exchange
Act), the Company shall furnish to the Representatives for review a
copy of each such proposed amendment or supplement, and the Company
shall not file any such proposed amendment or supplement to which a
Representative reasonably objects in writing within 48 hours after
receipt.

(b) Securities Act Compliance. After the date of this Agreement,
the Company shall promptly advise the Representatives in writing (i)
of the receipt of any comments of, or requests for additional or
supplemental information

-19-

<PAGE> 21

from, the Commission relating to the Registration Statement, (ii) of
the time and date of any filing of any post-effective amendment to the
Registration Statement or any amendment or supplement to any
preliminary prospectus or the Prospectus, (iii) of the time and date
that any post-effective amendment to the Registration Statement
becomes effective and (iv) of the issuance by the Commission of any
stop order suspending the effectiveness of the Registration Statement
or any post-effective amendment thereto or of any order preventing or
suspending the use of any preliminary prospectus or the Prospectus, or
of any proceedings to remove, suspend or terminate from listing or
quotation the Common Stock from any securities exchange upon which it
is listed for trading or included or designated for quotation, or of
the threatening or initiation of any proceedings for any of such
purposes. If the Commission shall enter any such stop order at any
time, the Company will use its best efforts to obtain the lifting of
such order at the earliest possible moment. Additionally, the Company
agrees that it shall comply with the provisions of Rules 424(b), 430A
and 434, as applicable, under the Securities Act and will use its
reasonable efforts to confirm that any filings made by the Company
under such Rule 424(b) were received in a timely manner by the
Commission.

(c) Amendments and Supplements to the Prospectus and Other
Securities Act Matters. If, during the Prospectus Delivery Period, any
event shall occur or condition shall exist as a result of which it is
necessary to amend or supplement the Prospectus in order to make the
statements therein, in the light of the circumstances when the
Prospectus is delivered to a purchaser, not misleading, or if in the
reasonable opinion of the Representatives or counsel for the
Underwriters it is otherwise necessary to amend or supplement the
Prospectus to comply with law, the Company agrees to promptly prepare
(subject to Section 3(A)(a) hereof), file with the Commission and
furnish at its own expense to the Underwriters and to dealers,
amendments or supplements to the Prospectus so that the statements in
the Prospectus as so amended or supplemented will not, in the light of
the circumstances when the Prospectus is delivered to a purchaser, be
misleading or so that the Prospectus, as amended or supplemented, will
comply with law.

(d) Copies of any Amendments and Supplements to the Prospectus.
The Company agrees to furnish the Representatives, without charge,
during the Prospectus Delivery Period, as many copies of the
Prospectus and any amendments and supplements thereto (including any
documents incorporated or deemed incorporated by reference therein) as
the Representatives may reasonably request.

(e) Blue Sky Compliance. The Company shall cooperate with the
Representatives and counsel for the Underwriters to qualify or
register the Common Shares for sale under (or obtain exemptions from
the application of)

-20-

<PAGE> 22

the Blue Sky or state securities laws or Canadian provincial
securities laws of those jurisdictions designated by the
Representatives, shall comply with such laws and shall continue such
qualifications, registrations and exemptions in effect so long as
required for the distribution of the Common Shares. The Company shall
not be required to qualify as a foreign corporation or to take any
action that would subject it to general service of process in any such
jurisdiction where it is not presently qualified or where it would be
subject to taxation as a foreign corporation. The Company will advise
the Representatives promptly of the suspension of the qualification or
registration of (or any such exemption relating to) the Common Shares
for offering, sale or trading in any jurisdiction or any initiation or
threat of any proceeding for any such purpose, and in the event of the
issuance of any order suspending such qualification, registration or
exemption, the Company shall use its best efforts to obtain the
withdrawal thereof at the earliest possible moment.

(f) Use of Proceeds. The Company shall apply the net proceeds
from the sale of the Common Shares sold by it in the manner described
under the caption "Use of Proceeds" in the Prospectus.

(g) Transfer Agent. The Company shall maintain, at its expense, a
registrar and transfer agent for the Common Stock.

(h) Earnings Statement. As soon as practicable, the Company will
make generally available to its security holders and to the
Representatives an earnings statement (which need not be audited)
covering the twelve-month period ending November 25, 2000 that
satisfies the provisions of Section 11(a) of the Securities Act.

(i) Periodic Reporting Obligations. During the Prospectus
Delivery Period the Company shall file, on a timely basis, with the
Commission and, to the extent required under the regulations thereof,
the Nasdaq National Market all reports and documents required to be
filed under the Exchange Act.

(j) Agreement Not To Offer or Sell Additional Securities. During
the period of 90 days following the date of the Prospectus, the
Company will not, without the prior written consent of BAS (which
consent may be withheld at the sole discretion of BAS), directly or
indirectly, sell, offer, contract or grant any option to sell, pledge,
transfer or establish an open "put equivalent position" within the
meaning of Rule 16a-1(h) under the Exchange Act, or otherwise dispose
of or transfer, or announce the offering of, or file any registration
statement under the Securities Act in respect of, any shares of Common
Stock, options or warrants to acquire shares of the Common Stock or
securities exchangeable or exercisable for or convertible into shares
of Common Stock (other than as contemplated by this Agreement with
respect to

-21-

<PAGE> 23

the Common Shares); provided, however, that the Company may: (i) issue
shares of its Common Stock or options to purchase its Common Stock, or
Common Stock upon exercise of options, pursuant to any stock option,
stock bonus or other stock plan or arrangement described in the
Prospectus, but only if the holders of such shares, options, or shares
issued upon exercise of such options, agree in writing with BAS not to
sell, offer, dispose of or otherwise transfer any such shares or
options during such 90 day period without the prior written consent of
BAS (which consent may be withheld at the sole discretion of BAS) or,
in the case of stock options, such options may not be exercised during
such 90 day period; (ii) file one or more registration statements on
Form S-8 covering shares of Common Stock issuable pursuant to any
stock option or stock purchase plan described in the Prospectus; or
(iii) issue shares of Common Stock, or securities exchangeable or
exercisable for or convertible into shares of Common Stock, as payment
for all or part of the purchase price of an acquisition by the Company
of another company or business, provided the total number of shares of
Common Stock issuable in connection with such acquisition (including
shares issuable upon exchange, exercise or conversion of any other
securities of the Company issued in connection with such acquisition)
does not exceed 10% of the number of shares of Common Stock
outstanding immediately prior to such acquisition, and provided
further that each person or entity receiving any such shares or
securities in connection with such acquisition agrees in writing with
BAS not to sell, offer, dispose of or otherwise transfer any such
shares or securities during such 90 day period without the prior
written consent of BAS (which consent may be withheld at the sole
discretion of BAS).

(k) Future Reports to the Representatives. During the period of
five years hereafter the Company will furnish to each Representative
(with the copy to BAS to be sent to 600 Montgomery Street, San
Francisco, CA 94111 Attention: Edward H. Schweitzer): (i) as soon as
practicable after the end of each fiscal year, copies of the Annual
Report of the Company containing the balance sheet of the Company as
of the close of such fiscal year and statements of income,
stockholders' equity and cash flows for the year then ended and the
opinion thereon of the Company's independent public or certified
public accountants; (ii) as soon as practicable after the filing
thereof, copies of each proxy statement, Annual Report on Form 10-K,

report filed by the Company with the Commission, the NASD or any
securities exchange; and (iii) as soon as available, copies of any
report or communication of the Company mailed generally to holders of
its capital stock.

B. COVENANTS OF THE SELLING STOCKHOLDERS. Each Selling Stockholder
further covenants and agrees, severally and not jointly, with each Underwriter:

-22-
<PAGE> 24

(a) Agreement Not to Offer or Sell Additional Securities. Such
Selling Stockholder will not, without the prior written consent of BAS
(which consent may be withheld in its sole discretion), directly or
indirectly, sell, offer, contract or grant any option to sell
(including without limitation any short sale), pledge, transfer,
establish an open "put equivalent position" within the meaning of Rule
16a-1(h) under the Exchange Act, or otherwise dispose of any shares of
Common Stock, options or warrants to acquire shares of Common Stock, or
securities exchangeable or exercisable for or convertible into shares
of Common Stock currently or hereafter owned either of record or

a 90-day period shall be used rather than the 60-day period set forth
therein) by the undersigned, or publicly announce the undersigned's
intention to do any of the foregoing, for a period commencing on the
date hereof and continuing through the close of trading on the date 90
days after the date of the Prospectus; provided, however, that such

securities (i) to the Company and (ii) to an officer of the Company,
provided such officer agrees in writing with BAS not to sell, offer,
dispose of or otherwise transfer any such shares or securities during
such 90-day period without the prior written consent of BAS (which
consent may be withheld at the sole discretion of BAS).

(b) Delivery of Forms W-8 and W-9. Such Selling Stockholder
will deliver to the Representatives prior to the First Closing Date a
properly completed and executed United States Treasury Department Form
W-8 (if the Selling Stockholder is a non-United States person) or Form

BAS, on behalf of the several Underwriters, may, in its sole
discretion, waive in writing the performance by the Company or any Selling
Stockholder of any one or more of the foregoing covenants or extend the time for
their performance.

SECTION 4. PAYMENT OF EXPENSES. The Company agrees to pay all costs,
fees and expenses incurred in connection with the performance of its obligations

and the Canadian provincial securities laws, and, if requested by the
Representatives, preparing and printing a "Blue Sky Survey" or memorandum, and
any supplements thereto, advising the Underwriters of such qualifications,

for such Selling Stockholders, (ii) fees and expenses of the Custodian and (iii)
expenses and taxes incident to the sale and delivery of the Common Shares to be

Agreement). This Section 4 shall not affect or modify any separate, valid
agreement relating to the allocation of payment of expenses between the Company,
on the one hand, and the Selling Stockholders, on the other hand.

If any condition specified in this Section 5 is not satisfied
when and as required to be satisfied, this Agreement may be terminated by the
Representatives by notice to the Company and an Attorney-in-Fact at any time on
or prior to the First Closing Date and, with respect to the Optional Common
Shares (if not purchased on the First Closing Date), at any time prior to the
Second Closing Date, which termination shall be without liability on the part of
any party to any other party, except that this paragraph, Section 4, Section 6,

SECTION 6. REIMBURSEMENT OF UNDERWRITERS' EXPENSES. If this Agreement
is terminated by the Representatives pursuant to Section 5, clauses (i), (v) or
(vi) of Section 11 or Section 17, or if the sale to the Underwriters of the
Common Shares on the First Closing Date is not consummated because of any
refusal, inability or failure on the part of the Company or a Selling
Stockholder to perform any agreement herein or to comply with any provision
hereof, the Company agrees to reimburse the Representatives and the other
Underwriters severally, upon demand for all out-of-pocket expenses that shall
have been reasonably incurred by the Representatives and the other Underwriters
in connection with the proposed purchase and the offering and sale of the Common
Shares, including but not limited to fees and disbursements of counsel, printing
expenses, travel expenses, postage, facsimile and telephone charges.

SECTION 7. EFFECTIVENESS OF THIS AGREEMENT.

This Agreement shall not become effective until the later of

by the Commission to the Company of the effectiveness of the Registration
Statement under the Securities Act, and the notification by the Company to the
Representatives of the receipt of such notification by the Commission.

-28-
<PAGE> 30

Prior to such effectiveness, this Agreement may be terminated
by any party by notice to each of the other parties hereto, and any such
termination shall be without liability on the part of (a) the Company or the
Selling Stockholders to any Underwriter, except that the Company shall be
obligated to reimburse the expenses of the Representatives and the Underwriters
pursuant to Section 4 hereof, (b) of any Underwriter to the Company or any
Selling Stockholder, or (c) of any party hereto to any other party, except that
the provisions of this paragraph, Section 8 and Section 9 shall at all times be
effective and shall survive such termination.

SECTION 8. INDEMNIFICATION.

(a) Indemnification of the Underwriters. The Company and each
of the Selling Stockholders, jointly and severally, agree to indemnify
and hold harmless each Underwriter, its officers and employees, and
each person, if any, who controls any Underwriter within the meaning of
the Securities Act and the Exchange Act against any loss, claim,
damage, liability or expense, as incurred, to which such Underwriter or
such controlling person may become subject, under the Securities Act,
the Exchange Act or other federal or state statutory law or regulation,
or at common law or otherwise (including in settlement of any
litigation, if such settlement is effected with the written consent of
the Company), insofar as such loss, claim, damage, liability or expense
(or actions in respect thereof as contemplated below) arises out of or
is based (i) upon any untrue statement or alleged untrue statement of a
material fact contained in the Registration Statement, or any amendment
thereto, including any information deemed to be a part thereof pursuant
to Rule 430A or Rule 434 under the Securities Act, or the omission or
alleged omission therefrom of a material fact required to be stated
therein or necessary to make the statements therein not misleading; or
(ii) upon any untrue statement or alleged untrue statement of a
material fact contained in any preliminary prospectus or the
Prospectus (or any amendment or supplement thereto), or the omission
or alleged omission therefrom of a material fact necessary in order to
make the statements therein, in the light of the circumstances under
which they were made, not misleading; or (iii) in whole or in part
upon any inaccuracy in the representations and warranties of the
Company or the Selling Stockholders contained herein; or (iv) in whole
or in part upon any failure of the Company or the Selling Stockholders
to perform their respective obligations hereunder or under law; or (v)
any act or failure to act or any alleged act or failure to act by any
Underwriter in connection with, or relating in any manner to, the
offering contemplated hereby, and which is included as part of or
referred to in any loss, claim, damage, liability or action arising
out of or based upon any matter covered by clause (i) or (ii) above;
and to reimburse each Underwriter and each such controlling person for
any and all expenses (including the reasonable fees and disbursements
of counsel chosen by BAS) as such expenses are reasonably incurred by
such Underwriter

-29-

<PAGE> 31

or such controlling person in connection with investigating,
defending, settling, compromising or paying any such loss, claim,
damage, liability, expense or action. Notwithstanding the foregoing:
(A) neither the Company nor any Selling Stockholder shall be liable
under clause (v) of the preceding sentence to the extent that a court
of competent jurisdiction shall have determined by a final judgment
that such loss, claim, damage, liability or action resulted directly
from any such acts or failures to act undertaken or omitted to be
taken by such Underwriter through its bad faith, negligence or willful
misconduct; (B) the indemnity and reimbursement agreements in the
preceding sentence shall not apply to any loss, claim, damage,
liability or expense to the extent, but only to the extent, arising
out of or based upon any untrue statement or alleged untrue statement
or omission or alleged omission made in reliance upon and in
conformity with written information furnished to the Company by the
Representatives expressly for use in the Registration Statement, any
preliminary prospectus or the Prospectus (or any amendment or
supplement thereto); (C) with respect to any preliminary prospectus,
the indemnity and reimbursement agreements in the preceding sentence
shall not inure to the benefit of any Underwriter from whom the person
asserting any loss, claim, damage, liability or expense purchased
Common Shares, or any person controlling such Underwriter, if copies
of the Prospectus were timely delivered to the Underwriter pursuant to
Section 2 and a copy of the Prospectus (as then amended or
supplemented if the Company shall have furnished any amendments or
supplements thereto) was not sent or given by or on behalf of such
Underwriter to such person, if required by law so to have been
delivered, at or prior to the written confirmation of the sale of the
Common Shares to such person, and if the Prospectus (as so amended or
supplemented) would have cured the defect giving rise to such loss,
claim, damage, liability or expense; (D) the indemnity and
reimbursement agreements of a Selling Stockholder set forth in clauses
(iii) and (iv) of the preceding sentence shall not apply to any
inaccuracy in the representations and warranties of the Company or any
other Selling Stockholder or to any failure of the Company or any
other Selling Stockholder to perform their respective obligations
hereunder or under law; (E) the liability of each Selling Stockholder
under the indemnity and reimbursement agreements in the preceding
sentence, or otherwise for a breach of such Selling Stockholder's
representations or warranties set forth in this Agreement, shall be
limited to an amount equal to the public offering price of the Common
Shares sold by such Selling Stockholder, less the underwriting
discount, as set forth on the front cover page of the Prospectus; and
(F) the Company and the Selling Stockholders may agree, as among
themselves and without limiting the rights of the Underwriters under
this Agreement, as to the respective amounts of such liability for
which they each shall be responsible. The indemnity and reimbursement
agreements set forth in this Section 8(a) shall be in addition to any
liabilities that the Company and the Selling Stockholders may
otherwise have.

-30-

<PAGE> 32

(b) Indemnification of the Company, its Directors and Officers
and the Selling Stockholders. Each Underwriter agrees, severally and
not jointly, to indemnify and hold harmless the Company, each of its
directors, each of its officers who signed the Registration Statement,
the Selling Stockholders and each person, if any, who controls the
Company or any Selling Stockholder within the meaning of the Securities
Act or the Exchange Act, against any loss, claim, damage, liability or
expense, as incurred, to which the Company, or any such director,
officer, Selling Stockholder or controlling person may become subject,
under the Securities Act, the Exchange Act, or other federal or state
statutory law or regulation, or at common law or otherwise (including
in settlement of any litigation, if such settlement is effected with
the written consent of such Underwriter), insofar as such loss, claim,
damage, liability or expense (or actions in respect thereof as
contemplated below) arises out of or is based upon: (i) any untrue
statement or alleged untrue statement of a material fact contained in
the Registration Statement, or any amendment thereto, including any
information deemed to be a part thereof pursuant to Rule 430A or Rule
434 under the Securities Act, or the omission or alleged omission
therefrom of a material fact required to be stated therein or necessary
to make the statements therein not misleading; or (ii) any untrue
statement or alleged untrue statement of a material fact contained in
any preliminary prospectus or the Prospectus (or any amendment or
supplement thereto), or the omission or alleged omission therefrom of
a material fact necessary in order to make the statements therein, in
the light of the circumstances under which they were made, not
misleading, in each case under clause (i) above and this clause (ii)
to the extent, but only to the extent, that such untrue statement or
alleged untrue statement or omission or alleged omission was made in
the Registration Statement, any preliminary prospectus, the Prospectus
(or any amendment or supplement thereto), in reliance upon and in
conformity with written information furnished to the Company by a
Representative expressly for use therein; or (iii) any failure of the
Underwriters to perform their respective obligations hereunder or
under law; and to reimburse the Company, and each such director,
officer, Selling Stockholder and controlling person for any and all
legal and other expenses as such expenses are reasonably incurred by
the Company, or any such director, officer, Selling Stockholder or
controlling person in connection with investigating, defending,
settling, compromising or paying any such loss, claim, damage,
liability, expense or action. The Company and each of the Selling
Stockholders hereby acknowledge that the only information that the
Underwriters have furnished to the Company expressly for use in the
Registration Statement, any preliminary prospectus or the Prospectus
(or any amendment or supplement thereto) are the statements set forth
in the table in the first paragraph and as the second and seventh
through tenth paragraphs under the caption "Underwriting" in the
Prospectus; and the Underwriters confirm that such statements are
correct. The

-31-

<PAGE> 33

indemnity and reimbursement agreements set forth in this Section 8(b)
shall be in addition to any liabilities that each Underwriter may
otherwise have.

(c) Notifications and Other Indemnification Procedures.
Promptly after receipt by an indemnified party under this Section 8 of
notice of the commencement of any action, such indemnified party will,
if a claim in respect thereof is to be made against an indemnifying
party under this Section 8, notify the indemnifying party in writing
of the commencement thereof, but the omission so to notify the
indemnifying party will not relieve it from any liability which it may
have to any indemnified party for contribution or otherwise than under
the indemnity agreement contained in this Section 8 or to the extent
it is not prejudiced as a proximate result of such failure. In case
any such action is brought against any indemnified party and such
indemnified party seeks or intends to seek indemnity from an
indemnifying party, the indemnifying party will be entitled to
participate in, and, to the extent that it shall elect, jointly with
all other indemnifying parties similarly notified, by written notice
delivered to the indemnified party promptly after receiving the
aforesaid notice from such indemnified party, to assume the defense
thereof with counsel reasonably satisfactory to such indemnified
party; provided, however, if the defendants in any such action include
both the indemnified party and the indemnifying party and the
indemnified party shall have reasonably concluded that a conflict may
arise between the positions of the indemnifying party and the
indemnified party in conducting the defense of any such action or that
there may be legal defenses available to it and/or other indemnified
parties which are different from or additional to those available to
the indemnifying party, the indemnified party or parties shall have
the right to select separate counsel to assume such legal defenses and
to otherwise participate in the defense of such action on behalf of
such indemnified party or parties. Upon receipt of notice from the
indemnifying party to such indemnified party of such indemnifying
party's election so to assume the defense of such action and approval
by the indemnified party of counsel, the indemnifying party will not
be liable to such indemnified party under this Section 8 for any legal
or other expenses subsequently incurred by such indemnified party in
connection with the defense thereof unless (i) the indemnified party
shall have employed separate counsel in accordance with the proviso to
the next preceding sentence (it being understood, however, that the
indemnifying party shall not be liable for the fees and expenses of
more than one separate counsel (together with local counsel), approved
by the indemnifying party (BAS in the case of Section 8(b) and Section
9), representing the indemnified parties who are parties to such
action) or (ii) the indemnifying party shall not have employed counsel
satisfactory to the indemnified party to represent the indemnified
party within a reasonable time after notice of commencement of the
action, in each of which cases the

-32-

<PAGE> 34

reasonable fees and expenses of counsel shall be at the expense of the
indemnifying party.

(d) Settlements. The indemnifying party under this Section 8
shall not be liable for any settlement of any proceeding effected
without its written consent, but if settled with such consent or if
there be a final judgment for the plaintiff, the indemnifying party
agrees to indemnify the indemnified party against any loss, claim,
damage, liability or expense by reason of such settlement or judgment;
provided that in the case of a final judgment, such indemnity shall be
only to the extent provided in Section 8(a), 8(b) or 8(c), as the case
may be. Notwithstanding the foregoing sentence, if at any time an
indemnified party shall have requested an indemnifying party to
reimburse the indemnified party for fees and expenses of counsel as
contemplated by Section 8(c) hereof, the indemnifying party agrees that
it shall be liable for any settlement of any proceeding effected
without its written consent if (i) such settlement is entered into more
than 30 days after receipt by such indemnifying party of the aforesaid
request, (ii) such indemnifying party shall have received notice of the
specific terms of such settlement at least 15 days prior to such
settlement being effected, and (iii) such indemnifying party shall not
have reimbursed the indemnified party in accordance with such request
prior to the date of such settlement. No indemnifying party shall,
without the prior written consent of the indemnified party, effect any
settlement, compromise or consent to the entry of judgment in any
pending or threatened action, suit or proceeding in respect of which
any indemnified party is or could have been a party and indemnity was
or could have been sought hereunder by such indemnified party, unless
such settlement, compromise or consent includes an unconditional
release of such indemnified party from all liability on claims that are
the subject matter of such action, suit or proceeding.

SECTION 9. CONTRIBUTION. If the indemnification provided for in Section
8 is for any reason held to be unavailable to or otherwise insufficient to hold
harmless an indemnified party in respect of any losses, claims, damages,
liabilities or expenses referred to therein, then each indemnifying party shall
contribute to the aggregate amount paid or payable by such indemnified party, as
incurred, as a result of any losses, claims, damages, liabilities or expenses
referred to therein (i) in such proportion as is appropriate to reflect the
relative benefits received by the Company and the Selling Stockholders, on the
one hand, and the Underwriters, on the other hand, from the offering of the
Common Shares pursuant to this Agreement or (ii) if the allocation provided by
clause (i) above is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of the Company and the Selling Stockholders,
on the one hand, and the Underwriters, on the other hand, in connection with the
statements in or omissions from any preliminary prospectus, the

-33-

<PAGE> 35

Prospectus or the Registration Statement (or any amendment or supplement to any
of the foregoing) or inaccuracies in the representations and warranties herein
which resulted in such losses, claims, damages, liabilities or expenses, as well
as any other relevant equitable considerations. The relative benefits received
by the Company and the Selling Stockholders, on the one hand, and the
Underwriters, on the other hand, in connection with the offering of the Common
Shares pursuant to this Agreement shall be deemed to be in the same respective
proportions as the total net proceeds from the offering of the Common Shares
pursuant to this Agreement (before deducting expenses) received by the Company
and the Selling Stockholders, and the total underwriting discount received by
the Underwriters, in each case as set forth on the front cover page of the
Prospectus (or, if Rule 434 under the Securities Act is used, the corresponding
location on the Term Sheet) bear to the aggregate public offering price of the
Common Shares as set forth on such cover page or such Term Sheet, as the case
may be. The relative fault of the Company and the Selling Stockholders, on the
one hand, and the Underwriters, on the other hand, shall be determined by
reference to, among other things, whether any such untrue or alleged untrue
statement of a material fact or omission or alleged omission to state a material
fact or any such inaccurate or alleged inaccurate representation or warranty
relates to information supplied by the Company or the Selling Stockholders, on
the one hand, or the Underwriters, on the other hand, and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission.

The amount paid or payable by a party as a result of the
losses, claims, damages, liabilities and expenses referred to above shall be
deemed to include, subject to the limitations set forth in Section 8(c), any
legal or other fees or expenses reasonably incurred by such party in connection
with investigating, defending, settling or compromising any action or claim. The
provisions set forth in Section 8(c) with respect to notice of commencement of
any action shall apply if a claim for contribution is to be made under this
Section 9; provided, however, that no additional notice shall be required with
respect to any action for which notice has been given under Section 8(c) for
purposes of indemnification.

The Company, the Selling Stockholders and the Underwriters
agree that it would not be just and equitable if contribution pursuant to this
Section 9 were determined by pro rata allocation (even if the Underwriters were
treated as one entity for such purpose) or by any other method of allocation
which does not take account of the equitable considerations referred to in this
Section 9.

Notwithstanding the provisions of this Section 9, no
Underwriter shall be required to contribute any amount in excess of the
underwriting discount received by such Underwriter in connection with the Common
Shares underwritten by it and distributed to the public nor shall any Selling
Stockholder be required to contribute any amount in excess of the public
offering price of the Common Shares sold by such

-34-

<PAGE> 36

Selling Stockholder, less the underwriting discount, as set forth on the front
cover page of the Prospectus. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. The Underwriters' obligations to contribute pursuant to this
Section 9 are several, and not joint, in proportion to their respective
underwriting commitments as set forth opposite their names in SCHEDULE A. For
purposes of this Section 9, each officer and employee of an Underwriter and each
person, if any, who controls an Underwriter within the meaning of the Securities
Act and the Exchange Act shall have the same rights to contribution as such
Underwriter, and each director of the Company, each officer of the Company who
signed the Registration Statement, and each person, if any, who controls the
Company within the meaning of the Securities Act and the Exchange Act shall have
the same rights to contribution as the Company, and each person, if any, who
controls a Selling Stockholder within the meaning of the Securities Act and the
Exchange Act shall have the same rights to contribution as such Selling
Stockholder.

SECTION 10. DEFAULT OF ONE OR MORE OF THE SEVERAL UNDERWRITERS. If, on
the First Closing Date or the Second Closing Date, as the case may be, any one
or more of the several Underwriters shall fail or refuse to purchase Common
Shares that it or they have agreed to purchase hereunder on such date, and the
aggregate number of Common Shares which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase does not exceed 10% of the
aggregate number of the Common Shares to be purchased on such date, the other
Underwriters shall be obligated, severally, in the proportions that the number
of Firm Common Shares set forth opposite their respective names on SCHEDULE A
bears to the aggregate number of Firm Common Shares set forth opposite the names
of all such non-defaulting Underwriters, or in such other proportions as may be
specified by the Representatives with the consent of the non-defaulting
Underwriters, to purchase the Common Shares which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase on such date. If, on the
First Closing Date or the Second Closing Date, as the case may be, any one or
more of the Underwriters shall fail or refuse to purchase Common Shares and the
aggregate number of Common Shares with respect to which such default occurs
exceeds 10% of the aggregate number of Common Shares to be purchased on such
date, and arrangements satisfactory to the Representatives and the Company for
the purchase of such Common Shares are not made within 48 hours after such
default, this Agreement shall terminate without liability of any non-defaulting
party to any other party except that the provisions of this sentence, Section 4,
Section 8 and Section 9 shall at all times be effective and shall survive such
termination. In any such case either the Representatives or the Company shall
have the right to postpone the First Closing Date or the Second Closing Date, as
the case may be, but in no event for longer than seven days in order that the
required changes, if any, to the Registration Statement and the Prospectus or
any other documents or arrangements may be effected.

<PAGE> 37

As used in this Agreement, the term "Underwriter" shall be
deemed to include any person substituted for a defaulting Underwriter under this
Section 10. Any action taken under this Section 10 shall not relieve any
defaulting Underwriter from liability in respect of any default of such
Underwriter under this Agreement.

SECTION 11. TERMINATION OF THIS AGREEMENT. Prior to the First Closing
Date this Agreement may be terminated by the Representatives by notice given to
the Company and the Custodian if at any time (i) trading or quotation in any of
the Company's securities shall have been suspended or limited by the Commission
or by the Nasdaq Stock Market; (ii) trading in securities generally on either
the Nasdaq Stock Market or the New York Stock Exchange shall have been suspended
or limited, or minimum or maximum prices shall have been generally established
on any of such stock exchanges by the Commission or the NASD; (iii) a general
banking moratorium shall have been declared by any of federal, New York or
California authorities; (iv) there shall have occurred any outbreak or
escalation of national or international hostilities or any crisis or calamity,
or any change in the United States or international financial markets, or any
substantial change or development involving a prospective substantial change in
United States' or international political, financial or economic conditions, as
in the judgment of the Representatives is material and adverse and makes it
impracticable to market the Common Shares in the manner and on the terms
described in the Prospectus or to enforce contracts for the sale of securities;
(v) in the judgment of the Representatives there shall have occurred any
Material Adverse Change; or (vi) the Company shall have sustained a loss by
strike, fire, flood, earthquake, accident or other calamity of such character as
in the judgment of the Representatives may interfere materially with the conduct
of the business and operations of the Company regardless of whether or not such
loss shall have been insured. Any termination pursuant to this Section 11 shall
be without liability on the part of (a) the Company or the Selling Stockholders
to any Underwriter, except that the Company and the Selling Stockholders shall
be obligated to reimburse the expenses of the Representatives and the other
Underwriters pursuant to Sections 4 and 6 hereof, (b) any Underwriter to the
Company or any Selling Stockholder, or (c) of any party hereto to any other
party except that the provisions of this sentence, Section 8 and Section 9 shall
at all times be effective and shall survive such termination.

SECTION 12. REPRESENTATIONS AND INDEMNITIES TO SURVIVE DELIVERY. The
respective indemnities, agreements, representations, warranties and other
statements of the Company, of its officers, of the Selling Stockholders and of
the several Underwriters set forth in or made pursuant to this Agreement will
remain in full force and effect, regardless of any investigation made by or on
behalf of any Underwriter, the Company or the Selling Stockholders or any of
their partners, officers or directors or any controlling person, as the case may
be, and will survive

Stockholders (other than such defaulting Selling Stockholders), or (ii) purchase

Underwriters shall have the right, by written notice from the Representatives to
the Company and the Custodian, to postpone the First Closing Date or the Second
Closing Date, as the case may be, but in no event for longer than seven days in

Ladies and Gentlemen:

We are familiar with the Registration Statement on Form S-3
(Registration No. 333-85899), as amended by Amendment No. 1 thereto (as amended,
the "Registration Statement"), filed by Charles River Associates Incorporated, a
Massachusetts corporation (the "Company"), with the Securities and Exchange
Commission under the Securities Act of 1933, as amended. The Registration
Statement relates to the proposed public offering by the Company of 200,000
shares (the "Company Shares") of its Common Stock, without par value (the
"Common Stock"), to be issued by the Company and to the proposed public offering
by certain stockholders of the Company (the "Selling Stockholders") of an
aggregate of 2,100,000 additional shares (the "Stockholder Shares") of such
Common Stock. (The foregoing number of Stockholder Shares assumes the exercise
in full of the over-allotment option described in the Registration Statement.)

We are familiar with the Company's Articles of Organization and all
amendments thereto and restatements thereof, its By-Laws and all amendments
thereto and restatements thereof, the records of meetings and consents of its
Board of Directors and of its stockholders provided to us by the Company, and
its stock records. In addition, we have examined and relied on the originals or
copies certified or otherwise identified to our satisfaction of all such
corporate records of the Company and such other instruments and other
certificates of public officials, officers and representatives of the Company
and such other persons, and we have made such investigations of law, as we have
deemed appropriate as a basis for the opinions expressed below.

Based on the foregoing, it is our opinion that:

1. The Company has corporate power adequate for the issuance of the
Company Shares in accordance with the Registration Statement. The Company has
taken all necessary corporate action required to authorize the issuance and sale
of the Company Shares. When certificates for the

<PAGE> 2

Charles River Associates Incorporated

Page 2

Company Shares have been duly executed and countersigned, and delivered against
due receipt of consideration therefor as described in the Registration
Statement, the Company Shares will be legally issued, fully paid and
non-assessable.

2. Upon the due execution, countersignature and delivery of
certificates for the Stockholder Shares, the Stockholder Shares will be legally
issued, fully paid and non-assessable.

We consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to us under the heading "Legal
Matters" in the prospectus forming part of the Registration Statement.

Very truly yours,

Foley, Hoag & Eliot LLP

CHARLES RIVER ASSOCIATES INCORPORATED

INDEMNITY AGREEMENT

This Indemnity Agreement is made as of ____________, 1999 by and among
Charles River Associates Incorporated, a Massachusetts corporation (the
"Company"), and the stockholders of the Company named in EXHIBIT A hereto (the
"Selling Stockholders").

WHEREAS, the Company and the Selling Stockholders propose to sell an
aggregate of up to 2,300,000 shares of the common stock, without par value (the
"Common Stock"), of the Company to the several underwriters (the "Underwriters")
named in that certain underwriting agreement (the "Underwriting Agreement") of
even date herewith by and among the Company, the Selling Stockholders, Banc of
America Securities LLC, William Blair & Company, L.L.C. and Salomon Smith Barney
Inc., as representatives of the Underwriters, upon the terms described in the
Underwriting Agreement; and

WHEREAS, pursuant to Section 8 of the Underwriting Agreement, the
Selling Stockholders have agreed to indemnify the Underwriters in certain
respects and contribute to the payment of certain amounts and the Selling
Stockholders desire that the Company agree to indemnify them in certain respects
and contribute to the payment of certain amounts as hereinafter provided;

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

1. INDEMNIFICATION OF THE SELLING STOCKHOLDERS. The Company shall
indemnify and hold harmless each Selling Stockholder, and each person, if any,
who controls any Selling Stockholder within the meaning of Section 15 of the
Securities Act of 1933, as amended (the "Securities Act"), or Section 20 of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), from and
against any loss, claim, damage, liability or expense, as incurred, to which
such Selling Stockholder or such controlling person may become subject, under
the Securities Act, the Exchange Act or other federal or state statutory law or
regulation, at common law, under Section 8 or Section 9 of the Underwriting
Agreement, or otherwise (including in settlement of any litigation, if such
settlement is effected with the written consent of such Selling Stockholder or
such controlling person, as the case may be), insofar as such loss, claim,
damage, liability or expense (or actions in respect thereof as contemplated
below) arises out of or is based (i) upon any failure, omission or alleged
failure or omission on the part of the Company, in connection with the
Registration Statement, any preliminary prospectus or the Prospectus (or any
amendment or supplement thereto) or the offering contemplated thereby, to comply
with any provision of the Securities Act and the then applicable rules and
regulations of the Securities and Exchange Commission or other federal agency at
the time charged with administration of the Securities Act; (ii) upon any untrue
statement or alleged untrue statement of a material fact contained in the
Registration Statement, or any amendment thereto, including any information
deemed to be a part thereof pursuant to Rule 430A or Rule 434 under the
Securities Act, or the omission or alleged omission therefrom of a material fact
required to be stated therein or necessary to make the statements therein not
misleading; (iii) upon any untrue statement or alleged untrue statement of a
material fact contained in any preliminary

<PAGE> 2

prospectus or the Prospectus (or any amendment or supplement thereto), or the
omission or alleged omission therefrom of a material fact necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading; (iv) in whole or in part upon any inaccuracy in the
representations and warranties of the Company contained in the Underwriting
Agreement; (v) in whole or in part upon any failure of the Company to perform
its obligations under the Underwriting Agreement or under law; (vi) upon any act
or failure to act or any alleged act or failure to act by any Underwriter in
connection with, or relating in any manner to, the offering contemplated by the
Underwriting Agreement, and which is included as part of or referred to in any
loss, claim, damage, liability or action arising out of or based upon any matter
covered by clause (ii) or (iii) above; and shall reimburse each Selling
Stockholder and each such controlling person for any and all expenses (including
the reasonable fees and disbursements of not more than one separate counsel
(together with local counsel) for the Selling Stockholders) as such expenses are
reasonably incurred by such Selling Stockholder or such controlling person in
connection with investigating, defending, settling, compromising or paying any
such loss, claim, damage, liability, expense or action. Notwithstanding the
foregoing, the indemnity and reimbursement agreements in the preceding sentence
shall not apply to any loss, claim, damage, liability or expense to the extent,
but only to the extent, that it arises out of or is based upon any untrue
statement or alleged untrue statement or omission or alleged omission made in
reliance upon and in conformity with written information furnished to the
Company by such Selling Stockholder expressly for use in the Registration
Statement, any preliminary prospectus or the Prospectus (or any amendment or
supplement thereto). The indemnity and reimbursement agreements set forth in
this Section 1 shall be in addition to any liabilities that the Company may
otherwise have.

2. NOTIFICATION AND OTHER INDEMNIFICATION PROCEDURES. Promptly after
receipt by an indemnified party under Section 1 of notice of the commencement of
any action, such indemnified party shall, if a claim in respect thereof is to be
made against the Company under Section 1, notify the Company in writing of the
commencement thereof, but the omission so to notify the Company will not relieve
the Company from any liability which the Company may have to any indemnified
party for contribution or otherwise than under the indemnity agreement contained
in Section 1 or to the extent the Company is not prejudiced as a proximate
result of such failure. In case any such action is brought against any
indemnified party and such indemnified party seeks or intends to seek indemnity
from the Company, the Company will be entitled to participate in, and, to the
extent that it shall elect by written notice delivered to the indemnified party
promptly after receiving the aforesaid notice from such indemnified party, to
assume the defense thereof with counsel selected by the Company; provided,
however, that if the defendants in any such action include both the indemnified
party and the Company and the indemnified party shall have reasonably concluded
that a conflict may arise between the positions of the Company and the
indemnified party in conducting the defense of any such action or that there may
be legal defenses available to such indemnified party and/or other indemnified
parties that are different from or additional to those available to the Company,
the indemnified party or parties shall have the right to select separate
counsel, satisfactory to the Company, to assume such legal defenses and
otherwise to participate in the defense of such action on behalf of such
indemnified party or parties. Upon receipt of notice from the Company to such
indemnified party of the Company's election so to assume the defense of such
action, the Company will not be liable to such indemnified party under Section 1
for any legal or other expenses subsequently incurred by such indemnified party
in connection with the defense thereof unless (i) the indemnified party shall
have employed separate counsel in accordance with the proviso to the

2
<PAGE> 3

next preceding sentence (it being understood, however, that the Company shall
not be liable for the fees and expenses of more than one separate counsel
(together with local counsel), satisfactory to the Company, representing the
indemnified parties who are parties to such action) or (ii) the Company shall
not have employed counsel to represent the indemnified party within a reasonable
time after notice of commencement of the action, in each of which cases the
reasonable fees and expenses of counsel shall be at the expense of the Company.
As a condition to indemnification hereunder, each indemnified party shall
cooperate fully with the Company in the defense of any action with respect to
which indemnification is to be sought, and, at the Company's expense, shall
provide all such documents and take all such actions which the Company may
reasonably request in connection with such defense.

3. SETTLEMENTS. The Company shall not be liable for any settlement
of any proceeding effected without its written consent, but if settled with such
consent or if there be a final judgment for the plaintiff, the Company shall
indemnify the indemnified party against any loss, claim, damage, liability or
expense by reason of such settlement or judgment. The Company shall not, without
the prior written consent of the indemnified party, effect any settlement,
compromise or consent to the entry of judgment in any pending or threatened
action, suit or proceeding in respect of which any indemnified party is or could
have been a party and indemnity was or could have been sought hereunder by such
indemnified party, unless such settlement, compromise or consent includes an
unconditional release of such indemnified party from all liability on claims
that are the subject matter of such action, suit or proceeding.

4. CONTRIBUTION.

(a) If the indemnification provided for in Section 1 is for any
reason held to be unavailable to or otherwise insufficient to hold
harmless an indemnified party in respect of any losses, claims,
damages, liabilities or expenses referred to therein, then the Company
shall contribute to the aggregate amount paid or payable by such
indemnified party, as incurred, as a result of any losses, claims,
damages, liabilities or expenses referred to therein (i) in such
proportion as is appropriate to reflect the relative benefits received
by the Company, on the one hand, and the indemnified party, on the
other hand, from the offering of the Common Shares pursuant to the
Underwriting Agreement or (ii) if the allocation provided by clause (i)
above is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in
clause (i) above but also the relative fault of the Company, on the one
hand, and the indemnified party, on the other hand, in connection with
the statements in or omissions from any preliminary prospectus, the
Prospectus or the Registration Statement (or any amendment or
supplement to any of the foregoing) or inaccuracies in the
representations and warranties of the Company in the Underwriting
Agreement that resulted in such losses, claims, damages, liabilities or
expenses, as well as any other relevant equitable considerations. The
relative benefits received by the Company, on the one hand, and the
indemnified party, on the other hand, in connection with the offering
of the Common Shares pursuant to the Underwriting Agreement shall be
deemed to be in the same proportion as the total net proceeds from the
offering (before deducting expenses) received by the Company bears to
the total net proceeds from the offering received by the indemnified
party. The relative fault of the Company, on the one hand, and the
indemnified party, on the other hand, shall be determined by reference
to,

among other things, whether any such untrue or alleged untrue statement
of a material fact or omission or alleged omission to state a material
fact or any such inaccurate or alleged inaccurate representation or
warranty relates to information supplied by the Company, on the one
hand, or the indemnified party, on the other hand, and the parties'
relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.

(b) The amount paid or payable by a party as a result of the
losses, claims, damages, liabilities and expenses referred to above
shall be deemed to include, subject to the limitations set forth in
Section 1 and Section 2, any legal or other fees or expenses reasonably
incurred by such party in connection with investigating, defending,
settling or compromising any action or claim. The provisions set forth
in Section 2 with respect to notice of commencement of any action shall
apply if a claim for contribution is to be made under this Section 4;
provided, however, that no additional notice shall be required with
respect to any action for which notice has been given under Section 2
for purposes of indemnification.

(c) The Company and the Selling Stockholders agree that it would
not be just and equitable if contribution pursuant to this Section 4
were determined by pro rata allocation (even if the Selling
Stockholders were treated as one entity for such purpose) or by any
other method of allocation which does not take account of the equitable
considerations referred to in this Section 4.

(d) No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. For purposes of this Section 4, each person, if any,
who controls a Selling Stockholder within the meaning of Section 15 of
the Securities Act or Section 20 of the Exchange Act shall have the
same rights to contribution as such Selling Stockholder.

5. CAPITALIZED TERMS. Except as otherwise specified, capitalized
terms used herein which are not otherwise specifically defined herein shall have
the meanings given them in the Underwriting Agreement. Notices required or
permitted hereunder shall be given in the manner prescribed in Section 13 of the
Underwriting Agreement.

6. SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon, and
inure to the benefit of, the Company, the Selling Stockholders, and their
respective controlling persons, officers, directors, successors, heirs,
executors, administrators and assigns.

7. GOVERNING LAW. This Agreement shall be governed by, and construed
and enforced in accordance with, the laws of the Commonwealth of Massachusetts,
without regard to its principles of conflicts of laws.
