                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.  NATURE OF BUSINESS AND BASIS OF PRESENTATION

 The Company

   Prime Response, Inc. ("PRI") together with its consolidated subsidiaries
("Prime Response") is a leading provider of integrated eMarketing software
solutions that enable businesses with large customer bases to create, manage and
execute highly targeted internet and traditional marketing campaigns to build
more loyal and profitable customer relationships.  Prime Response's customers
consist primarily of Fortune 1000 businesses as well as leading e-commerce
businesses primarily based in the United States and Europe.  Prime Response
sells its products through multiple distribution channels including direct sales
and resellers.

   The consolidated financial statements include the accounts of PRI and its
wholly-owned domestic and foreign subsidiaries.  All intercompany accounts and
transactions have been eliminated.  The balance sheet at March 31, 2000, and the
statement of operations for the three months ended March 31, 2000 and 1999, and
cash flows for the three months ended March 31, 2000, and 1999 have been
prepared without audit.  In the opinion of management, these financial
statements reflect all adjustments that are necessary for a fair presentation of
the result for and as of the periods shown.  The results of operations for such
periods are not necessarily indicative of the results expected for a full fiscal
year or for any future period.  These financial statements should be read in
conjunction with the financial statements and related notes included in the
Company's Registration Statement on Form S-1 (file number 0-28873) filed with
the Securities and Exchange Commission.

2.  INITIAL PUBLIC OFFERING

   On March 3, 2000, Prime Response completed an initial public offering of its
common stock.  All 3,500,000 shares covered by Prime Response's Registration
Statement on Form S-1, were sold by Prime Response at a price of $18.00 per
share, less an underwriting commission of $1.26 per share. Net proceeds to the
Company, after deducting underwriting commissions and offering expenses, were
approximately $57.0 million. Upon the consummation of Prime Response's initial
public offering on March 3, 2000, all of the then outstanding Series A, B and C
Preferred Stock automatically converted into common stock. (See Note 6).

                                       6

3.  SIGNIFICANT ACCOUNTING POLICIES

     Net Loss per Share

   Basic net loss per share is computed by dividing the net loss for the period
by the weighted average number of common shares outstanding during the period.
Diluted net loss per share does not differ from basic net loss per share since
potential common shares from conversion of preferred stock and exercise of stock
options and warrants are antidilutive for all periods presented.

   Net loss per share for the three months ended March 31, 2000 and 1999 is
computed using the weighted average number of common shares outstanding. Net
loss available to common stockholders includes preferred stock dividends of $0.5
million and $0.6 million for the three months ended March 31, 2000 and 1999,
respectively, as well as participation payments in cash and stock totalling
$39.4 million for the three months ended March 31, 2000, in connection with the
Series A, B and C preferred stock.  The number of shares to be issued for the
participation payment is calculated based on $12.00 per share.

Basic and diluted weighted average shares outstanding for the three months ended
March 31, 2000 exclude the potential common shares from stock options because to
include such shares would have been antidilutive. As of March 31, 2000, 1.6
million potential shares were outstanding.

 Accounting Pronouncements

   In June 1998, the FASB issued Statement of Financial Accounting Standards No.
133 "Accounting for Derivative Instruments and Hedging Activities" ("SFAS
133"). SFAS 133 establishes a new model for accounting for derivatives and
hedging activities and supersedes and amends a number of existing standards.
SFAS 133 is effective for fiscal years beginning after June 15, 1999, but
earlier application is permitted as of the beginning of any fiscal quarter
subsequent to June 19, 1998.  Upon initial application, all derivatives are
required to be recognized in the statement of financial position as either
assets or liabilities and measured at fair value.  In addition, all hedging
relationships must be reassessed and documented pursuant to the provisions of
SFAS 133.  Prime Response does not anticipate that this pronouncement will have
a material effect on its reported results or financial position.

   In December 1999, the Securities and Exchange Commission ("SEC") issued Staff
Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition in Financial
Statements." SAB 101 summarizes the SEC's view in applying generally accepted
accounting principles to selected revenue recognition issues. The application of
the guidance in SAB 101 (as amended by SAB 101A) will be required in the
Company's second quarter of the fiscal year 2000. The effects of applying this
guidance, if any, will be reported as a cumulative effect adjustment resulting
from a change in accounting principle. Prime Response's evaluation of SAB 101 is
not yet complete.

4.  OTHER ASSETS

  During  March 2000, Prime Response entered into an OEM agreement with a
provider of customer optimization technology.  Prime Response will pay royalties
for all licenses sold that integrate the customer optimization technology.
Prime Response will pay $1.0 million as an initial non-refundable prepayment of
these royalties. In addition, Prime Response received 40,000 warrants with an
exercise price of $9.73 and a five-year term. Prime Response has calculated the
fair value of the warrants using the Black Scholes model with the following
assumptions: 5 year life (life of warrant), 6.35% risk-free rate of return, zero
dividends and 85.19% volatility. Based on this calculation, the fair value of
the warrants is approximately $276,000. The $1.0 million to be paid has been
recorded as a long term asset on the balance sheet at March 31, 2000 with
$276,000 being allocated to the warrants and the remainder will be recorded as
royalty expense in cost of sales as license sales are recognized.


5.  LONG-TERM DEBT

     On October 28, 1999, Prime Response entered into an agreement with Greyrock
Capital which provided for a term loan of $2.0 million which was received by
Prime Response upon execution of the agreement.  The agreement also allowed
Prime Response to borrow against outstanding receivable balances up to $3.0
million. During March 2000, Prime Response repaid the $2.0 million term loan.
As of March 31, 2000, no amounts had been borrowed against the receivable
portion of this agreement.

                                       7

     During January 2000, Prime Response entered into an agreement with Kite
Limited evidenced by a promissory note in the amount of $4.3 million for the
repurchase of 1,249,500 shares of redeemable common stock from a former
shareholder at $3.42 per share.  Prime Response repaid the note in full during
March 2000, and recorded the shares as treasury stock.


6.  REDEEMABLE CONVERTIBLE PREFERRED STOCK

 Conversion

   Upon the consummation of the IPO, the Series A, B and C preferred shares were
converted into a total of 6,324,000 shares of common stock.  Each share of
Series A, B and C preferred stock converted into 3.1282, 0.7858 and 0.75 shares,
respectively, of common stock.

 Dividends

   Upon the consummation of the IPO, the holders of Series A and B preferred
stock received cumulative dividends in the amount of $3.59 and $0.51 per share,
respectively.  Cumulative dividends on the Series A and B preferred stock were
$4.5 million and $1.0 million, respectively.  All of the Series A dividends were
paid in 374,821 shares of common stock.  Series B dividends were paid $0.9
million in cash and 6,661 in shares of common stock.  The holders of Series C
preferred stock were not entitled to dividends.

 Participation Payment

   Upon the consummation of the IPO, the holders of Series A and C preferred
stock received, in addition to accrued dividends and the common stock conversion
feature, $20.52 and $3.00 per share, respectively, paid in 2,433,382 shares of
common stock.  The holders of Series B preferred stock received, in addition to
accrued dividends and the conversion feature, $6.00 per share which was paid
with $9.5 million in cash and 56,875 in shares of common stock.


7.  STOCKHOLDERS' EQUITY

 Stock Split

   In November 1999, Prime Response's board of directors approved a 0.75-for-1
reverse split of common stock.  The stock split took place on February 2, 2000.
All share and per share amounts in the accompanying consolidated financial
statements have been adjusted retroactively.


 Stock Options

   In connection with the grant of certain stock options to employees during the
three months ended March 31, 2000, Prime Response recorded deferred stock
compensation of approximately $0.3 million, representing the difference between
the estimated fair market value of the common stock on measurement date and the
exercise price. Compensation related to options, which vest over time, was
recorded as a component of stockholders' equity and is being amortized over the
vesting periods of the related options. Prime Response recorded compensation
expense of $14,000 in relation to these options. In addition, Prime Response
recorded compensation expense of approximately $0.3 million during the three
months ended March 31, 2000 relating to the amortization of deferred
compensation recorded during 1999 and the acceleration of a former employees'
options. Compensation expense is disclosed as a non-cash expense in the
consolidated Statement of Operations line items.

 Underwriters Over-Allotment

     On April 3, 2000, the underwriters of the initial public offering exercised
the over-allotment option to purchase 525,000 shares.  After deducting
underwriting commissions and expenses, net proceeds to the Company were
approximately $8.8 million.


 Redeemable Common Stock

  Andersen Consulting or its affiliate had the right to require Prime Response
to repurchase the 428,000 shares it purchased in December 1999 for $4.0 million.
The put right terminated upon the IPO and accordingly these shares were moved
from redeemable common stock to common stock at March 31, 2000.  In addition,
during the quarter ended March 31, 2000, Prime Response repurchased 1,249,500
shares of common stock from a former shareholder that had the right to put these
shares to Prime Response prior to September 30, 2000.  These shares were
recorded as redeemable common stock at December 31, 1999.


8.   SEGMENT ANALYSIS

   Prime Response earned all of its revenue from external customers.  Prime
Response is organized into three segments, software licenses, services and
support and applications hosting, to reflect the key sales lines.  The
distribution of revenues and total assets by geographic location is as follows
(in thousands):

ITEM 2:  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

   This Form 10-Q contains forward-looking statements within the meaning of
Section 21E of the Securities Exchange Act of 1934, as amended. For this
purpose, statements contained herein that are not statements of historical fact
may be deemed to be forward-looking statements. Without limiting the foregoing,
the words "believes," "anticipates," "plans," "expects" and similar expressions
are intended to identify forward-looking statements. These forward-looking
statements involve risks and uncertainties and are not guarantees of future
performance. Actual results may differ materially from those indicated in such
forward-looking statements as a result of certain factors including, but not

Results."

OVERVIEW

   Prime Response is a leading provider of integrated eMarketing software
solutions that enable businesses with large customer bases to create, manage and
execute highly targeted Internet and traditional marketing campaigns that build
more loyal and profitable customer relationships.  We have over 12 years of
experience in the use of technology to plan and manage marketing programs.  We
were founded in 1987 in the United Kingdom.  Prior to 1999, our corporate
headquarters were in London, England, and our primary focus was on the European
market.  In 1998, we began to increasingly target the North American market, and
in July 1999, moved our corporate headquarters to Cambridge, Massachusetts.

   Since 1995, we have incurred significant development costs to develop our
technology and new software products, particularly to introduce our latest
generation of Internet-based marketing management solutions.  With the
introduction of these products, we anticipate that research and development
expenses will stabilize and will decrease as a percentage of total revenues.  We
intend to continue to expand our direct sales force and increase marketing
expenditures relating to the introduction of our new product offerings, and as a
result, we expect sales and marketing expenses to continue to grow, in absolute
dollars.

   We generate revenues principally from:

   .   licensing our software products directly to clients;

   .   providing related professional services, including implementation,
       consulting, support and training; and

   .   providing applications hosting services, including providing marketing
       database outsourcing services.

   Our license agreements typically require our clients to pay an upfront
license fee for one or more software solutions for a specified number of
customer records in their database.  The amount of the license fee varies
principally depending upon the size of the client's database and number of
databases.  Clients can subsequently pay additional license fees to allow
additional entities within their corporate structure to access our applications
or to purchase additional solutions.

 Andersen Consulting Relationship

   On December 6, 1999, Prime Response and Andersen Consulting entered into a
joint marketing agreement and, along with an affiliate of Andersen Consulting, a
stock and warrant purchase agreement.  Pursuant to the stock and warrant
purchase agreement, an affiliate of Andersen Consulting purchased 428,000 shares
of common stock and Andersen Consulting received a warrant to purchase 682,000
shares of common stock.  This warrant has an exercise price of $9.35 per share
and vests upon the earlier to occur  of September 9, 2000, or the date of an
acquisition of Prime Response by another person or entity.  The aggregate
purchase price paid by Andersen Consulting for the shares of common stock and
this warrant was $4.0 million.  Andersen Consulting has no performance
obligations under the stock and warrant purchase agreement or this warrant.

   Prime Response has recorded the stock at fair value and based on a value
equal to 90% of the estimated mid-point of the initial public offering range.
The fair value of the stock is $4,622,400. Prime Response calculated the fair
value of the warrants on date of grant using Black Scholes model with the
following assumptions: 7 year useful life (life of warrants), 6.07% risk-free
interest rate, zero dividends and 85.19% volatility. Based on this calculation,
the extended fair value of the warrants is $6,536,080. Prime Response has
recorded an intangible asset of $7,010,000 which is equal to the excess of the
aggregate fair values of the common stock and warrants over the purchase price.
This asset is being amortized as a non-cash sales and marketing expense over its
estimated useful life of four years, which reflects the term of the marketing
agreement.

   Prime Response issued a performance warrant to purchase 375,000 shares of
common stock to Andersen Consulting.  Of this amount, 300,000 shares will vest
in share increments determined by the extent to which $2.0 billion exceeds Prime
Response's market capitalization at the time of its initial public offering.  An
additional 75,000 shares will vest in increments of 7,500 shares for each $100.0
million that Prime Response's market capitalization exceeds $2.0 billion, up to
a maximum market capitalization of $3.0 billion.  This warrant has an exercise
price of $9.35 per share.  Prime Response also issued a performance warrant to
purchase 375,000 shares of common stock to Andersen Consulting which will vest
in increments of 10,500 shares for each $1.0 million of sales resulting from
joint marketing efforts up to $25.0 million and then in increments of 4,500
shares for each $1.0 million of sales from $25.0 million to $50.0 million.  This
warrant has an exercise price of $9.35 per share.  As of March 31, 2000 there
had not been any vesting of the above warrants.

   All warrants have a seven-year term.  In the event that the marketing
agreement is terminated as a result of a breach by Andersen Consulting, no
further vesting under the warrants will occur, but those warrants already
exercisable will remain exercisable during their term to the extent they are
vested at the time of the termination.

   Andersen Consulting or its affiliate had the right to require Prime Response
to repurchase the 428,000 shares for $4.0 million.  The put right terminated
upon the IPO.

   Prime Response is obligated to engage Andersen Consulting for consulting
services of at least $1.0 million before December 31, 2001.  If designated sales
targets are met, Andersen Consulting is obligated to provide up to $1.0 million
in funding for joint marketing efforts, business development personnel,
structure feedback and sales support.  None of these funds had been expended as
of March 31, 2000.  The expenditure of these funds will be controlled by a
committee comprised of both Andersen Consulting and Prime Response personnel.

</TABLE>


THREE MONTHS ENDED MARCH 31, 2000 AND 1999

 Revenues

   Total revenues increased by $3.7 million, or 99.2%, to $7.5 million for the
three months ended March 31, 2000,  from $3.8 million for the three months ended
March 31, 1999.

   Software Licenses.   Software license revenues increased by $3.5 million, or
325.5%, to $4.6 million for the three months ended March 31, 2000, from $1.1
million for the three months ended March 31, 1999.  Software license revenues
increased to 61.0% of total revenues for the three months ended March 31, 2000,
from 28.6% of total revenues for the prior year.  The increase in software
license revenues was due primarily to growing market acceptance of our
Prime@Vantage products which were released for general availability during
December 1999.

   Services and Support.   Revenues from services and support increased by $0.4
million, or 24.6 %, to $2.1 million for the three months ended March 31, 2000,
from $1.7 million for the three months ended March 31, 1999. These revenues
decreased to 28.3% of total revenues for the three months ended March 31, 2000,
from 45.2% of total revenues for the previous year. The dollar increase in
service and support revenues was due primarily to an increase in the number of
sales of software licenses, which resulted in increased demand for services and
sales of software maintenance and technical support.

                                       12
<PAGE>

    Applications Hosting.   Revenues from applications hosting decreased by $0.2
million or 18.5%, to $0.8 million for the three months ended March 31, 2000,
from $1.0 million for the three months ended March 31, 1999.  These revenues
represented 10.7% of total revenues for the three months ended March 31, 2000,
compared to 26.2% of total revenues for the prior year.  The decrease as a
percentage of revenues is due primarily to the increase in revenues from
software licenses as the Company continues to shift its focus to increasing
software license revenue.

 Cost of Revenues

   Total cost of revenues increased by $1.2 million, or 76.0%, to $2.8 million
for the three months ended March 31, 2000, from $1.6 million for the three
months ended March 31, 1999.

    Software Licenses.   Software license costs consist primarily of expenses
incurred to translate software products and prepare related documents as well as
negligible expenses to manufacture, package and distribute our software
products.  The costs associated with the translation of software products and
preparation of related documents occurred during 1998.

   Services and Support.   Services and support costs include salary expense and
other related costs for our professional services, maintenance and telephone
support staffs, as well as third-party contractor expenses.  Services and
support costs increased by $1.1 million, or  131.3%, to $2.0 million in the
three months ended March 31, 2000, from $0.9 million in the three months ended
March 31, 1999. Services and support costs were 92.2% of services and support
revenues for the three months ended March 31, 2000, compared to 49.7% of such
revenues for the prior year.  The increase in services and support costs was
primarily due to (i) implementation services provided to our "early adopter"
customers and (ii) a lag in hiring professional service consultants which
resulted in the use of more expensive outside contractors to complete several
implementations.

   Applications Hosting.   Costs attributable to applications hosting consist
primarily of personnel-related costs and equipment maintained for the provision
of services to clients. These costs increased by $0.1 million, or 11.7%, to $0.9
million for the three months ended March 31, 2000, from $0.8 million for the
three months ended March 31, 1999. These costs were 107.2% of applications
hosting revenues for the three months ended March 31, 2000, compared to 78.2% of
such revenues for the prior year. Typically these costs have been relatively
fixed. However the increase in these costs for the three months ended March 31,
2000 results from the start up costs incurred for a new customer during the
quarter.

   The non-cash cost of revenues increased to $28,000 for the three months ended
March 31, 2000, from none for the three months ended March 31, 1999.  This
expense represents the amortization of stock compensation expense in connection
with the granting of stock options.  The expense results from the difference
between the estimated fair market value of the common stock on measurement date
and the exercise price of the option, which is being recognized over the vesting
period.


 Operating Expenses

   Sales and Marketing.   Sales and marketing expenses consist primarily of
salaries and other related costs for sales and marketing personnel, sales
commissions, travel, public relations and marketing materials and trade shows.
Sales and marketing expenses increased by $2.3 million, or 82.5%, to $5.1
million for the three months ended March 31, 2000, from $2.8 million for the
three months ended March 31, 1999.  Sales and marketing expenses decreased to
68.1% of total revenues for the three months ended March 31, 2000, compared to
74.3% for the prior year.  The increase in such expenses was due primarily to
increases in staffing and personnel related costs, as we continued to expand our
direct sales force and expand our presence in North America.  We anticipate that
sales and marketing expenses will continue to increase as we further expand our
direct sales force and invest heavily in the marketing and promotion of our new
generation of eMarketing management software products.

                                       13
<PAGE>

   The non-cash sales and marketing expense increased to $0.6 million for the
three months ended March 31, 2000, from $16,000 for the three months ended March
31,1999.  This expense represents (i) the amortization of stock compensation in
connection with the granting of stock options, which results from the difference
between the estimated fair market value of the common stock on measurement date
and the exercise price of the option which is being recognized over the vesting
period; and (ii) the amortization of the intangible asset recorded in connection
with the Andersen Consulting agreement.

   Research and Development.   Research and development expenses consist
primarily of personnel and equipment-related costs directly associated with the
development of both our existing and future products.  Research and development
expenses increased by $0.6 million, or 29.4%, to $2.5 million for the three
months ended March 31, 2000, from $1.9 million for the three months ended March
31, 1999. Research and development expenses decreased to 33.5% of total revenues
in the three months ended March 31, 2000, from 51.6% for the prior year. The
dollar increase in expenses reflects the investment to hire additional
development personnel and acquire equipment to support research and development
activities. The percentage decrease in costs was primarily due to (i) the
completion of the development activity associated with our new Prime@Vantage and
Prime@Vantage.com products, which occurred during fiscal 1999; and (ii) the
increase in our revenue base.

   The non-cash research and development expense increased to $31,000 for the
three months ended March 31, 2000, from none for the three months ended March
31, 1999.  This expense represents the amortization of stock compensation
expense in connection with the granting of stock options.  The expense results
from the difference between the estimated fair market value of the common stock
on measurement date and the exercise price of the option, which is being
recognized over the vesting period.

   General and Administrative.   General and administrative expenses consist
primarily of employee salaries and related expenses for executive, finance and
administrative personnel as well as external professional fees and certain
centrally-borne costs.  General and administrative expenses increased by $0.6
million, or  65.2%, to $1.4 million for the three months ended March 31, 2000,
from $0.8 million for the three months ended March 31, 1999.  These expenses
decreased to 18.6% of total revenues for the three months ended March 31, 2000,
from 22.4% for the prior year.  The decrease as a percentage of revenues was
primarily attributable to the increase in our revenue base.  During the quarter
ended March 31, 2000, we completed the recruitment and development of a
professional management team in North America. In addition, we also increased
our provision for bad debts by $0.2 million during the quarter ended March 31,
2000.

   The non-cash general and administrative expense increased to $29,000 for the
three months ended March 31, 2000, from none for the three months ended March
31, 1999.  This expense represents the amortization of stock compensation
expense in connection with the granting of stock options and restricted shares.
The expense results from the difference between the estimated fair market value
of the common stock on measurement date and the exercise price of the option,
which is being recognized over the vesting period.

   Amortization of Goodwill and Other Intangible Assets.   Amortization expense
decreased by $0.3 million, or 100.0%, to none for the three months ended March
31, 2000, from $0.3 million for the three months ended March 31, 1999.  This
expense is solely attributable to the acquisition of certain intellectual
property rights and other intangible assets related to the MIND software
product, which are fully amortized.

   Interest Income.   Interest income increased by $198,000, or 100%, to
$199,000 for the three months ended March 31, 2000, from $1,000 for the three
months ended March 31, 1999.  The increase is primarily due to interest income
earned on proceeds from the Company's initial public offering in March 2000.

   Interest Expense.   Interest expense increased by $151,000, or 457.6%, to
$184,000 for the three months ended March 31, 2000, from $33,000 for the three
months ended March 31, 1999. The increase is primarily due to interest expense
on the Company's credit facility, which was obtained in November 1999.

   Net Loss.    As a result of the increases in revenue, operating expenses,
depreciation and amortization, and net interest expense noted above, our net
loss increased by $1.3 million, or 32.4%, to $5.1 million for the three months
ended March 31, 2000, compared with a net loss of $3.8 million the three months
ended March 31, 1999.

LIQUIDITY AND CAPITAL RESOURCES

   On March 3, 2000 we completed our Initial Public offering ("IPO") in which we
sold 3,500,000 shares of common stock at $18.00 per share.  Net proceeds to the
Company after deducting underwriting commissions and estimated offering expenses
were approximately $57.0 million.  Prior to the IPO, our primary source of
funding had been through the private sale of convertible preferred stock and
attached warrants, which totaled $39.1 million in aggregate net proceeds as of
December 31, 1999.

   During April 2000, the underwriters of the IPO exercised their over-allotment
option to purchase an additional 525,000 shares.  At the offering price of
$18.00 we received an additional $8.8 million, net of underwriting commissions.

   In October 1999, we entered into a $5.0 million financing arrangement with
Greyrock Capital, a Bank of America company, providing an upfront term loan of
$2.0 million with the balance being funded against our receivables position
within the United States and in the United Kingdom.  The arrangement has a 12-
month renewable term.  The $2.0 million that was borrowed during 1999 was repaid
during the quarter ended March 31, 2000 with the proceeds from the IPO.

   Cash and cash equivalents were $38.2 million at March 31, 1999, compared to
$4.0 million at December 31, 1999. In addition, working capital at March 31,
2000, was $35.8 million compared to $(1.3) million at December 31, 1999.  The
increase from December 31, 1999 is primarily attributable to the proceeds from
the IPO.

   Net cash used in operating activities was $6.5 million during the quarter
ended March 31, 2000, and $3.8 million during the quarter ended March 31, 1999.
The majority of the cash used in operating activities during the quarter ended
March 31, 2000 results from costs incurred building an infrastructure to
penetrate the North American market.

   Capital expenditures were $0.5 million during the quarter ended March 31,
2000 and $0.2 million during the quarter ended March 31, 1999.  Due to the
expansion of staff and the scope of activities we may be required to expand our
office facilities which would require additional investment in furniture and
equipment.  In addition, we intend to continue to invest in our systems
infrastructure to better support our clients, improve the ongoing efficiency of
our product development process and facilitate internal communications and
virtual team working.

   Net cash provided by financing activities was $41.1 million during the
quarter ended March 31, 2000, and $5.9 million during the quarter ended March
31, 1999. In March 2000 we completed our IPO and received net proceeds of $57.0
million after deducting underwriting commissions and offering expenses. From
these net proceeds, the Company repaid certain indebtedness totalling $6.3
million and paid dividends and participation payments on the preferred stock
totalling $10.5 million.

   Our strategic initiatives include the rollout of our new web-enabled software
products Prime@Vantage and Prime@Vantage.com and the expansion of our United
States operations.  These initiatives will require a substantial amount of
capital as will personnel additions and the funding of operating losses and
working capital.


                                       15

   Prime Response is obligated to engage Andersen Consulting for consulting
services of at least $1.0 million during the period from contract execution to
December 31, 2001.  If designated sales targets are met, Andersen Consulting is
obligated to provide up to $1.0 million in funding for joint marketing efforts,
business development personnel, structure feedback and sales support.  None of
these funds had been expended as of March 31, 2000.  The expenditure of these
funds will be controlled by a committee comprised of both Andersen Consulting
and Prime Response personnel.

   As a result of our losses, we do not expect to pay United States income taxes
in the foreseeable future.

   It is the Company's belief that its existing balance of cash and cash
equivalents as well as the net proceeds of $8.8 million, received during April
2000, from the exercise of the underwriter's over-allotment, will be sufficient
to meet the Company's working capital and anticipated capital expenditure needs
for at least the next 12 months. Thereafter, the Company may require additional
sources of funds to continue to support our business. There can be no assurance
that such capital, if needed, will be available or will be available on terms
the Company finds acceptable.

IMPACT OF YEAR 2000

   Many currently installed computer systems and software products are coded to
accept or recognize only two digit entries in the date code field.  These
systems and software products will need to accept four digit entries to
distinguish 21st century dates from 20th century dates.  As a result, computer
systems and software used by many companies and governmental agencies may need
to be upgraded to comply with these Year 2000 requirements or risk system
failure or miscalculations causing disruptions of normal business activities.
To date, we have not experienced any material Year 2000 problems in our computer
systems or operations.  However, other companies, including us, could experience
latent Year 2000 problems.

FACTORS THAT MAY AFFECT RESULTS

    The following important factors, among other things, could cause Prime
Response's actual operating results to differ materially from those indicated or
suggested by forward-looking statements made in this Form 10-Q or presented
elsewhere by management from time to time.

WE HAVE INCURRED SUBSTANTIAL OPERATING LOSSES, AND WE MAY NOT BE PROFITABLE IN
THE FUTURE.

    In 1995, we began to transition from a marketing database service bureau
to a software company. Since that time, we have incurred substantial operating
losses. We cannot be certain if or when we will become profitable. Failure to
achieve profitability within the timeframe expected by investors or to maintain
profitability may adversely affect the market price of our common stock. In
recent periods, we have increased expenditures in certain areas, particularly in
sales and marketing in the United States and in product development. We expect
our sales and marketing expenses to continue to increase. As a result, we expect
to incur net losses and negative operating cash flow for the foreseeable future.
Although we have experienced revenue growth in recent periods, we cannot be
certain that these growth rates are sustainable, or that we will ever generate
revenues at a level sufficient to cover our anticipated expenses, if at all.

OUR QUARTERLY OPERATING RESULTS MAY FLUCTUATE BECAUSE WE DEPEND ON A SMALL
NUMBER OF LARGE ORDERS.

    We derive a significant portion of our software license revenues in each
quarter from a small number of relatively large orders. The criteria for a
client's acceptance of a product may delay our ability to recognize revenue
from the products we ship. Our operating results for a particular fiscal
period could be materially adversely affected if we are unable to complete
those transactions, or satisfy our clients' acceptance criteria, on schedule
at anticipated levels.

DISAPPOINTING QUARTERLY REVENUES OR OPERATING RESULTS COULD CAUSE THE PRICE OF
OUR COMMON STOCK TO FALL.

    Our quarterly revenues and operating results are difficult to predict and
may fluctuate significantly from quarter to quarter. Therefore, you should not
rely on period-to-period comparisons of revenues or results of operations as
an indication of future performance. If our quarterly revenues or operating
results fall below the expectations of investors or securities analysts, the
price of our common stock could fall substantially.

    Our quarterly license revenues may fluctuate as a result of a variety of
factors, including the following:

  .   software license revenues in any quarter depend on contracts closed,
      orders shipped and the satisfaction of clients' acceptance criteria in
      that quarter;

  .   the market in which we compete is relatively new and rapidly evolving;

  .   we expect that, for the foreseeable future, revenues will come from
      licenses to a small number of clients, so delays, cancellations of
      orders, or acceptance of our software by a few clients can
      significantly impact revenues within a quarter;


                                       16
<PAGE>

  .   our sales cycle is relatively long; and

  .   revenues will be affected by the timing of introduction of new
      products or product enhancements by us or our competitors.

    Any decline in license revenues could also cause a decline in our services
and support revenues in the same quarter or in subsequent quarters.

SEASONAL TRENDS MAY CAUSE OUR QUARTERLY OPERATING RESULTS TO FLUCTUATE, WHICH
MAY ADVERSELY AFFECT THE MARKET PRICE OF OUR COMMON STOCK.

    In the future, we may experience seasonality in our business, particularly
because we do a significant percentage of our business in Europe, which
typically experiences a slowdown in business during August, and because our
products typically involve a significant initial investment, the availability
of which is often dependent on a client's fiscal period. Accordingly, we may
generate lower revenues during the summer months and higher revenues during the
calender year-end months. If we do experience these revenue fluctuations,
market analysts and investors may not be able to predict our quarterly or
annual operating results, and if we fail to meet expectations of market
analysts or investors, the price of our common stock could decline.

OUR RESULTS OF OPERATIONS WOULD BE ADVERSELY AFFECTED IF OUR INVESTMENTS IN
PERSONNEL AND INFRASTRUCTURE DO NOT CORRESPOND WITH THE TIMING OF REVENUE
GENERATED AS A RESULT OF SUCH INVESTMENTS.

    Most of our expenses, such as employee compensation, sales and marketing
expenses, computer equipment costs and rent for properties, are either
relatively fixed in the short term or incurred in advance of sales. Moreover,
our expense levels are based in part on our expectations regarding future
revenues. As a result, if revenues for a particular quarter are below
expectations, we will most likely not be able to proportionately reduce
operating expenses for that quarter. Therefore, a shortfall in revenues would
have a disproportionate effect on our expected operating results for that
quarter and could cause the trading price of our common stock to decline.

WE MAY INCUR CHARGES AGAINST OUR EARNINGS WHICH COULD HAVE AN ADVERSE IMPACT ON
OUR RESULTS OF OPERATIONS.

    We have issued warrants which become exercisable upon the attainment of
certain revenue targets and market capitalization levels. Because we cannot
predict if and when these targets will be attained, we cannot predict when
charges to expenses related to these warrants will be incurred. Furthermore,
the amount of these charges will depend on the price of our common stock when
the warrants are earned.

WE ARE RELEASING A NEW PRODUCT FAMILY AND ARE DEPENDENT ON ITS MARKET
ACCEPTANCE.

    We have released the latest generation of our marketing management
solutions--Prime@Vantage, which introduces a new software architecture, and
Prime@Vantage.com, which introduces new functionality, including the ability to
generate immediate and personalized marketing initiatives over the internet.
Achievement of our overall business goals is dependent upon the sustained
market acceptance at desired pricing levels of these new products. If these
products do not achieve and sustain market acceptance due to bugs, a lack of
functionality considered important in the marketplace, or any other reason, we
will experience a material adverse effect on our business, prospects, operating
results and financial condition.


                                       17
<PAGE>

OUR FAILURE TO INCREASE OUR UNITED STATES REVENUES AND OPERATIONS WOULD
ADVERSELY AFFECT OUR OPERATING RESULTS AND FINANCIAL CONDITION.

    Although to date a significant portion of our revenues have been derived
from our international operations, and the growth of such revenues will remain
an important factor to the successful growth of our business, we believe that
we must continue to expand our marketing and sales activities, product and
service offerings and operations in the United States in order to achieve and
maintain profitability. Our failure to effectively manage expansion in the
United States could have a material adverse effect on the delivery of our
products and services, our ability to attract and retain key personnel and our
business operations and prospects.

WE MAY NOT BE ABLE TO CONTINUE TO DEVELOP NEW PRODUCTS OR ENHANCE EXISTING
PRODUCTS ON A TIMELY BASIS.

    To be competitive, we must continue to develop and introduce on a timely
basis new products and product enhancements. Our failure to develop and
introduce new products and enhancements successfully and on a timely basis, or
the failure of new products to achieve and sustain market acceptance, could
have a material adverse effect on our business, prospects, operating results
and financial condition. We are obligated under a limited number of client
contracts to deliver new products or product enhancements by specified dates,
and failure to do so could result in the loss of one or more of those clients
or expose us to contractual liability. We have in the past encountered
circumstances that made it impractical to provide required enhancements to a
customer, and we may be unable to do so on future occasions.

OUR SALES CYCLE IS RELATIVELY LONG AND DIFFICULT TO PREDICT.

    The decision by a prospective client to purchase our products frequently
involves several functional departments within its business. In addition, the
purchase and implementation of our products typically involve a significant
cost to our clients, including training and integration costs. These
implementations can also include a substantial commitment of resources by our
clients or their consultants over an extended period of time. As a result, our
sales cycle generally ranges from three to nine months, with our average sales
cycle lasting approximately six months. Consequently, the relatively long and
unpredictable nature of our sales cycle makes it difficult to predict our
revenues.

INTENSE COMPETITION MAY ADVERSELY AFFECT OUR FINANCIAL CONDITION AND OPERATING
RESULTS.

    The market for internet-based integrated eMarketing solutions is becoming
intensely competitive. If we are unable to compete effectively, our business,
prospects, financial condition and operating results would be materially
adversely affected. Some of our current and potential competitors have greater
name recognition and substantially greater financial, technical, marketing,
management, service, support and other resources than we do. Therefore, they
may be able to respond more quickly than we can to new or changing
opportunities, technologies, standards, or client requirements.

    In addition, we expect that new competitors will enter the market with
competing products as the size and visibility of the market opportunity
increases. We also expect that competition will increase as a result of
consolidations and formations of alliances among industry participants.
Increased competition could result in pricing pressures, reduced margins, and
failure of our products to achieve or maintain market acceptance.

WE DEPEND ON A FEW INDUSTRIES FOR MOST OF OUR SALES, AND WE MAY NOT CONTINUE TO
BE SUCCESSFUL IN THOSE MARKETS AND IN EXPANDING BEYOND THOSE LIMITED MARKETS.

    A substantial portion of our revenues have been derived from sales to
communications and media businesses, financial institutions, and retail and e-
commerce businesses. In order to reach and maintain profitability, we must
continue to succeed in these markets. We may not be successful in doing so. In
addition, we must expand the number of markets we address in order for our
business to grow as planned, and we may not be successful in doing so.


                                       18
<PAGE>

IF WE ARE UNABLE TO MANAGE OUR GROWTH AND THE RELATED EXPANSION IN OUR
OPERATIONS EFFECTIVELY, OUR BUSINESS MAY BE HARMED.

    Our ability to successfully offer products and services and implement our
business plan in a rapidly evolving market requires effective planning and
management. Our growth has placed, and our anticipated future operations will
continue to place, a significant strain on our management, information systems,
network and other resources. To manage future growth effectively, we must
continue to improve our financial and accounting systems and controls, enhance
our reporting systems and procedures, integrate new personnel and manage
expanded operations. We will also need to hire additional personnel and we may
be unable to recruit qualified employees as needed.

WE ARE LARGELY DEPENDENT ON OUR INTERNATIONAL OPERATIONS.

    In addition to our presence in the United States, we have offices in five
other countries and customers in more than 19 other countries. In the quarter
ended March 31, 2000, 62.5% of our total revenues resulted from sales outside
North America, reflecting our historical presence in the United Kingdom and
elsewhere in Europe. Although we believe that we must increase our operations in
the United States to reach and maintain profitability, we must also continue to
expand our sales in international markets for our business to grow as planned.
This may require us to establish additional international operations and hire
additional personnel. Our failure to do so in a timely and effective manner
would have a material adverse effect on our business, prospects, financial
condition and operating results. Our operations and our plans to expand
internationally may be affected by a number of risks, including:

  .   challenges inherent in managing geographically dispersed operations;

  .   the need to develop local distribution channels through third parties;

  .   multiple, conflicting and changing governmental laws and regulations;
      and

  .   foreign currency exchange rate fluctuations.

OUR FAILURE TO EXPAND OUR DIRECT SALES FORCE WOULD IMPEDE OUR REVENUE GROWTH
AND FINANCIAL CONDITION.

    To increase our revenues, we must increase the size of our direct sales
force. It can take a considerable amount of time to hire, train and integrate
new sales personnel. In addition, there is intense competition for qualified
sales personnel. We may not be successful in attracting, integrating,
motivating or retaining qualified personnel for these positions on a timely
basis or at all. A failure to do so would have a material adverse effect on our
business and operating results.

FAILURE TO EXPAND OUR RELATIONSHIPS WITH CONSULTING FIRMS AND SYSTEMS
INTEGRATORS WOULD IMPEDE ACCEPTANCE OF OUR PRODUCTS AND GROWTH OF OUR REVENUES.

    Consultants, systems integrators, and service providers who recommend,
install and support our products with their customers are a major source of our
sales. To increase our revenues and implementation capabilities, we must
continue to develop and expand relationships with consultants, systems
integrators, service providers and other potential industry partners. A failure
to do so would have a material adverse effect on our ability to generate
increased revenues. Consultants, systems integrators and service providers may
market or recommend products that compete with ours. Moreover, if these firms
fail to implement our products successfully for their clients, we may not have
the resources to implement our products on the schedule required by the client,
which could have a material adverse effect on our ability to generate increased
revenues.

OUR BUSINESS WILL BE ADVERSELY AFFECTED IF INTERNET SOLUTIONS ARE NOT WIDELY
ADOPTED.

    Because one of our new products addresses, among other markets, the
emerging market for internet marketing solutions, our future success depends in
part upon the widespread adoption of the internet as a primary medium for
commerce and business applications. The failure of this market to develop, or a
delay in


                                       19
<PAGE>

the development of this market, would have a material adverse effect on our
business, financial condition and operating results. The internet has
experienced, and is expected to continue to experience, significant user and
traffic growth, which has, at times, caused user frustration with slow access
and download times. The internet infrastructure may not be able to support the
demands placed on it by the continued growth upon which our success in part
depends. Moreover, critical issues concerning the commercial use of the
internet, such as security, reliability, cost, accessibility, taxation of e-
commerce and quality of service, remain unresolved and may negatively affect
the growth of internet use or the attractiveness of commerce and business
communication over the internet. In addition, the internet could suffer
declines in its viability due to delays in the development or adoption of new
standards and protocols to handle increased activity or due to increased
government regulation and taxation of internet commerce.

OUR REVENUES MIGHT BE HARMED BY A RESISTANCE TO ADOPT OUR SOFTWARE BY INTERNAL
INFORMATION TECHNOLOGY DEPARTMENTS.

    Some businesses may have already made a substantial investment in other
third-party or internally developed software designed to integrate data from
disparate sources and analyze this data or manage marketing campaigns. These
businesses may be reluctant to abandon these investments in favor of our
software. In addition, information technology departments of potential clients
may resist purchasing our software for a variety of other reasons, particularly
the potential displacement of their historical role in creating and running
software and concerns that packaged software products are not sufficiently
customizable for their enterprises. If the demand for our products does not
grow for any of these reasons, our revenues may be harmed.

IF OUR SECURITY SYSTEM IS BREACHED, OUR BUSINESS AND REPUTATION COULD SUFFER.

    We must securely receive and transmit confidential information over public
networks and maintain that information on internal systems. Our failure to
prevent security breaches could damage our reputation, expose us to risk of
loss or liability, result in a loss of our clients and adversely affect our
ability to obtain new clients. Although we have implemented network security
measures, our servers are vulnerable to computer viruses, which could lead to
interruptions, delays or loss of data. We may be required to expend significant
capital and other resources to license encryption technology and additional
technologies to protect against security breaches or to alleviate problems
caused by any breach.

OUR FAILURE TO OPERATE OUR PROFESSIONAL SERVICES ORGANIZATION AT A PROFIT WOULD
ADVERSELY AFFECT OUR FINANCIAL CONDITION.

    Our failure to operate our professional services organization at a profit
would have a material adverse effect on our operating results and financial
condition. To gain initial acceptance of our products by clients in our
targeted industries, we may elect on occasion to assist customers with the
implementation of our products at a loss. In the past, our cost of services
revenues have been significantly higher than our services revenues. We cannot
be certain that our professional services organization will achieve or sustain
profitability.


                                       20
<PAGE>

LOSS OF KEY PERSONNEL COULD ADVERSELY AFFECT OUR BUSINESS.

    Our future success depends to a significant degree on the skills,
experience and efforts of James Carling, our founder and Chief Technology
Officer, Peter J. Boni, our President and Chief Executive Officer, Allen Swann,
our President, International, Paul Lavallee, our President, Americas, and
Frederick Phillips, our Chief Financial Officer. The loss of the services of
any of these individuals could have a material adverse effect on us. We also
depend on the ability of our executive officers and other members of senior
management to work effectively as a team. The loss of one or more of our
executive officers and other members of senior management could have a material
adverse effect on us. Many of our executive officers, members of senior
management or other employees are not subject to an agreement that prohibits
them from competing with us after the termination of their employment with us.
We do not maintain "key man" insurance on any of our executive officers or
senior management personnel.

WE MAY BE UNABLE TO HIRE AND RETAIN THE SKILLED PERSONNEL WE NEED TO SUCCEED.

    Qualified personnel are in great demand throughout the software industry.
Our success depends in large part upon our ability to attract, train, motivate
and retain highly skilled employees, particularly sales and marketing personnel
and other senior personnel. Our failure to attract and retain the highly-
trained technical personnel that are integral to our product development,
professional services and support teams may limit the rate at which we can
develop new products or product enhancements. This could have a material
adverse effect on our business, prospects, operating results and financial
condition.

WE MAY BE UNABLE TO PROTECT OUR PROPRIETARY TECHNOLOGY RIGHTS.

    Our success depends to a significant degree upon the protection of our
software and other proprietary technology rights. We rely on trade secret,
copyright and trademark laws and confidentiality agreements with employees and
third parties, all of which offer only limited protection. Moreover, the laws
of the countries in which we develop and market our products may afford little
or no effective protection of our proprietary technology. The reverse
engineering, unauthorized copying or other misappropriation of our proprietary
technology could enable third parties to benefit from our technology without
paying us for it. This could have a material adverse effect on us. Legal
proceedings to enforce our intellectual property rights could divert the time
and attention of management, be expensive and involve uncertainty of success.

CLAIMS BY OTHER COMPANIES THAT OUR PRODUCTS INFRINGE THEIR PROPRIETARY RIGHTS,
COPYRIGHTS OR PATENTS COULD ADVERSELY AFFECT OUR FINANCIAL CONDITION.

    If any of our products are alleged to violate third-party proprietary
rights, we may be required to reengineer our products or seek to obtain
licenses from third parties to continue offering our products without
substantial reengineering. Any efforts to reengineer our products or obtain
licenses from third parties may be unsuccessful and, in any case, could
substantially increase our costs and have a material adverse effect on us. We
do not conduct comprehensive patent searches to determine whether the
technology used in our products infringes patents held by third parties. In
addition, product development is inherently uncertain in a rapidly evolving
technological environment in which there may be numerous patent applications
pending, many of which are confidential when filed, with regard to similar
technologies.

CLAIMS BY OTHER COMPANIES THAT OUR NAMES INFRINGE THEIR PROPRIETARY RIGHTS
COULD ADVERSELY AFFECT OUR FINANCIAL CONDITION.

    Third parties have claimed, and may in the future claim, that our company
name or our product names violate their trademark or trade name rights. We have
applied for registration of some of our trademarks in the United States, Canada
and the European Community but have not yet received any approvals. Our use of
the names Prime Response, Prime@Vantage and Prime@Vantage.com, as well as the
use of other names, may result in costly litigation, divert management's
attention and resources, cause product shipment delays, or require us to pay
damages or to enter into royalty or license agreements. We may be required to
stop using


                                       21
<PAGE>

certain names currently used for our products. Any of these events could have a
material adverse effect on our business, prospects, operating results and
financial condition.

OUR BUSINESS COULD BE ADVERSELY AFFECTED IF OUR PRODUCTS FAIL TO PERFORM
PROPERLY.

    Software products as complex as ours may contain undetected errors, or
bugs, which result in product failures, or otherwise fail to perform in
accordance with client expectations. Our products may be particularly
susceptible to bugs or performance degradation because of the emerging nature
of internet technologies and the stress that may be placed on our products by
the full deployment of our products over the internet. Product performance
problems could result in loss of or delay in revenues, loss of market share,
failure to achieve market acceptance, diversion of development resources, or
injury to our reputation, any of which could have a material adverse effect on
our business, prospects, operating results and financial condition.

WE COULD INCUR SUBSTANTIAL COSTS AS A RESULT OF PRODUCT LIABILITY CLAIMS
RELATING TO OUR CLIENTS' MARKETING EFFORTS.

    Our products may be critical to our clients' marketing efforts. If one of
our products fails, a client may assert a claim for substantial damages against
us, regardless of our responsibilities for such failure. Although our form of
license agreement contains provisions limiting liability, product liability
claims could require us to spend significant time and money in litigation or to
pay significant damages. There can be no assurance that our product liability,
errors and commissions or general liability insurance will prove sufficient to
cover one or more large claims, or that the insurer will not disclaim coverage
as to any future claim.

ACQUISITIONS COULD CAUSE FINANCIAL OR OPERATIONAL PROBLEMS.

    Our success depends on our ability to continually enhance and broaden our
product offerings in response to changing technologies, customer demands and
competitive pressures. To this end, we may choose to acquire new and
complementary businesses, products, or technologies instead of developing them
ourselves. We may face competition for acquisition targets from larger and more
established companies with greater financial resources, making it more
difficult for us to complete acquisitions. We do not know if we will be able to
complete any acquisitions, or whether we will be able to successfully integrate
any acquired business, operate it profitably or retain its key employees.
Integrating any business, product or technology we acquire could be expensive
and time-consuming, could disrupt our ongoing business and could distract our
management. In addition, in order to finance any acquisitions, we might need to
raise additional funds through public or private equity or debt financings. In
that event, we could be forced to obtain financing on terms that are not
favorable


                                       22
<PAGE>

to us and, ultimately, our stockholders. Specifically, in the case of an equity
financing, the issuance of additional stock would result in dilution to our
stockholders, and in the case of a debt financing, we may be forced to accept
restrictions on our ability to incur additional debt, make prepayments on
certain indebtedness, make acquisitions and other investments, issue additional
capital stock and engage in mergers and consolidations, all of which could
impede our long term plans for expansion and on our ability to pay dividends to
our stockholders. If we are unable to integrate any acquired entities, products
or technologies effectively, our business, financial condition and operating
results will suffer. In addition, any amortization of goodwill or other assets
or charges resulting from the costs of acquisitions could harm our business and
operating results.

OUR BUSINESS IS SUBJECT TO GOVERNMENT REGULATION OF THE INTERNET AND OTHER
LEGAL UNCERTAINTIES, WHICH COULD NEGATIVELY IMPACT OUR OPERATIONS.

    Laws and regulations directly applicable to communications or commerce over
the internet are becoming more prevalent. The United States Congress recently
enacted internet laws regarding privacy, copyrights, taxation and other
matters. In addition, the European Union recently enacted privacy regulations.
The laws governing the use of the internet, however, remain largely unsettled,
even in areas where there has been some legislative action. It may take years
to determine whether and how existing laws such as those governing intellectual
property, privacy, libel and taxation apply to the internet. In addition, the
growth and development of the market for online commerce may prompt calls for
more stringent consumer protection laws, both in the United States and abroad,
that may impose additional burdens on companies conducting business online. The
adoption or modification of laws or regulations relating to the internet could
adversely affect our business. In particular, new regulations affecting the use
of unsolicited e-mail advertising would impair our clients' marketing efforts
and could reduce the demand for our products.

PRIVACY CONCERNS AND LEGISLATION MAY LIMIT THE INFORMATION OUR CLIENTS CAN
GATHER, WHICH COULD REDUCE THE DEMAND FOR OUR PRODUCTS.

    Privacy concerns may cause website visitors to resist providing personal
data or avoid websites that track the internet behavioral information necessary
to support online profiling capabilities. Even the perception of security or
privacy concerns, whether or not valid, may have a similar effect. The European
Union recently adopted a directive addressing data privacy that may limit the
collection and use of certain information regarding internet users. This
directive may limit our clients' ability to target advertising or collect and
use information in certain European countries. In addition, legislative or
regulatory requirements may heighten these concerns if businesses must notify
website users that the data captured after visiting their websites may be used
to direct product promotion and advertising to that user. Other countries and
political entities, such as the European Union, have adopted these types of
restrictions. The United States may adopt similar legislation or regulatory
requirements. If privacy legislation is enacted or consumer privacy concerns
are not adequately addressed, our business, prospects, financial condition and
operating results could be harmed.

    Websites typically use bits of information keyed to a specific server, file
pathway or directory location, commonly referred to as "cookies," which are
placed on a customer's hard drive, possibly without the customer's knowledge or
consent, to track demographic information and target advertising. Our clients
may use cookies for a variety of reasons, including the collection of data
derived from the customer's internet activity. Most currently available
internet browsers allow our clients' customers to remove cookies at any time or
to prevent cookies from being stored on their hard drives. In addition, some
commentators, privacy advocates and governmental bodies have suggested limiting
or eliminating the use of cookies. Any reduction or limitation in the use of
cookies could limit the effectiveness of our clients' sales and marketing
efforts. The Federal Trade Commission and several states are investigating the
use by internet companies of personal information. New regulations regarding
the use of personal information could adversely impact the demand for our
products.
